Do patients with early-stage non–small cell lung cancer (NSCLC) benefit from continuing immunotherapy beyond surgery?

The short answer: Oncologists don’t know for sure.

Since October 2023, the US Food and Drug Administration (FDA) has approved three checkpoint inhibitors — pembrolizumab (Keytruda), durvalumab (Imfinzi), and most recently nivolumab (Opdivo) — alongside platinum-containing chemotherapy before surgery and as monotherapy after surgery to treat resectable NSCLC.

But the trials leading to each approval had a major design flaw. The studies failed to distinguish when patients with resectable NSCLC benefited from immunotherapy — before surgery, after surgery, or at both points.

That missing piece has left oncologists without definitive guidance on how best to treat their patients with resectable disease. 

Jamie E. Chaft, MD, a thoracic medical oncologist and attending physician at Memorial Sloan Kettering Cancer Center in New York City, was “surprised” that the FDA had approved the three immunotherapy combination regimens without this clarity. Clinicians are now left with studies that can’t evaluate the contribution of the neoadjuvant and adjuvant phases, she said.

But that may soon change.

In July, an FDA advisory committee met to discuss the pending approval of durvalumab.

During this July meeting, the FDA’s Oncologic Drugs Advisory Committee (ODAC) called out issues with AstraZeneca’s design of the trial, expressing concern that AstraZeneca had not followed the agency’s advice to compare patient outcomes with durvalumab in the neoadjuvant and adjuvant phases.

The ODAC panel ultimately voted unanimously in favor of requiring drug companies to demonstrate that patients need immunotherapy both before and after surgery in resectable NSCLC. Several panelists said this requirement should extend beyond NSCLC to other tumor types.

“We need to understand who needs what therapy when,” Daniel Spratt, MD, chairman of the FDA’s ODAC, told Medscape Medical News.

But even if the FDA does require drug companies to assess the benefit of immunotherapy pre- and post-surgery, will oncologists get the answers they need for their patients with resectable NSCLC? Or will the new costly trial design requirements dead-end progress in this space?

 

Treating Patients Without Clear Evidence

Despite the ODAC’s strong urging to require — not simply request — that drug companies show patients with resectable NSCLC benefit from immunotherapy in both the neoadjuvant and adjuvant settings, the advisory panel did not think durvalumab’s approval should be delayed until the neoadjuvant vs adjuvant question is answered.

A month later, in August, the FDA approved durvalumab for this indication.

Pembrolizumab (Keytruda, Merck) had already been approved 10 months earlier in the neoadjuvant and adjuvant settings in this setting. And most recently, in October, the FDA added nivolumab (Opdivo, Bristol Myers Squibb) to these approvals.

No trial, however, identified when patients benefited from the drug.

Without this understanding, patients may be taking immunotherapy unnecessarily, at significant expense and toxicity risk.

“Toxicities from immunotherapy can occur at any time after initiation,” said Joshua Eric Reuss, MD, a thoracic medical oncologist at Georgetown University’s Lombardi Comprehensive Cancer Center in Washington, DC. And these “risks definitely continue into the adjuvant period.”

So far, the available evidence does suggest that the neoadjuvant phase of immunotherapy confers the greatest benefit, while adjuvant immunotherapy — which can last a year or longer — may expose patients to more costs and toxicities, with no clear benefit.

A 2024 meta-analysis, which included four trials of neoadjuvant-adjuvant immunotherapy and one trial of neoadjuvant immunotherapy in resectable NSCLC, suggested that the addition of adjuvant immunotherapy did not improve event-free survival (hazard ratio [HR], 0.90; P = .59) or overall survival (HR, 1.18; P = .51) compared with neoadjuvant immunotherapy alone.

According to Spratt, “It’s very clear that the neoadjuvant phase is the more important of the two phases.” Given that, “we’re probably overtreating some patients,” said Spratt, also chairman of Radiation Oncology at University Hospitals Seidman Cancer Center and Case Western Reserve University in Cleveland.

Chaft agreed that “there’s very little data that we need the postoperative phase, and what data we do have is post hoc and limited.”

This evidence gap “has created considerable dilemmas” for oncologists and patients who are faced with “the challenge of deciding which therapeutic options or approach are best suited for each individual,” experts wrote in recent consensus recommendations from the International Association for the Study of Lung Cancer.

Clinicians may ultimately be left to make decisions about prescribing postoperative immunotherapy based on their experience and comfort level.

When Chaft’s patients have a pathologic complete response with immunotherapy and chemotherapy in the neoadjuvant phase, “I’m comfortable stopping because the data would suggest they’re almost certainly cured,” she said.

For patients who have viable disease after neoadjuvant therapy, continuing an immunotherapy postoperatively when it didn’t work preoperatively “is not going to make a difference,” Chaft explained. In these cases, Chaft would look to enroll them in a clinical trial evaluating a different regimen because of the risk for relapse.

With patients who did well preoperatively but still have tumor left at the time of surgery, she would discuss continuing the immunotherapy or participating in a trial, she said.

All the FDA-approved regimens are covered by insurance, said Chaft. Clinicians are most comfortable with pembrolizumab because it is the most widely used immunotherapy in advanced NSCLC, she said. But, she added, “there’s really no strong differentiating data between any of the studies; all the results look very comparable.”

When assessing whether a patient may benefit from immunotherapy after surgery, Reuss looks at a range of factors, including disease stage, histology, gene mutations, and pathologic response. Reuss also weighs patient preferences. A patient coming from another country might only want a neoadjuvant regimen, for instance, he said.

That “isn’t exactly the kind of the level one evidence that one likes to see when making treatment decisions,” said Reuss. “Without prospective data, all we can do is cross-trial comparisons and assessment of subgroups.”

If a new regimen comes along that improves outcomes or decision-making, “I think we would pivot to that in a heartbeat,” he said.

 

But Will FDA Follow ODAC’s Recommendation?

“ODAC has made their point clear,” said Chaft. “Our patients deserve to know that whatever added risk and cost they’re incurring is merited by a clinical outcome.”

Despite the ODAC’s recommendation, it’s not guaranteed that the FDA will follow it.

An FDA spokesperson did not confirm the agency’s decision on the matter but noted that the FDA is “incorporating the panel’s advice.”

Spratt thinks that, going forward, companies will be held to “a higher bar,” but it’s unclear what that bar will look like.

“Whether this is a mandate or a strong recommendation, I think industry is definitely paying attention,” Spratt said. Companies that do not follow the guidance may risk not having their drug approved, “unless it’s just an absolute huge slam dunk of a major benefit to patients.”

In fact, according to Chaft, drug makers seeking approvals of novel entities in this space “won’t have a choice” but to follow any new trial design requirements from the FDA.

Still, getting answers may be a challenge.

Drug companies with immunotherapies already on the market are unlikely to invest the resources to conduct trials comparing the neoadjuvant and adjuvant settings, said Chaft. “It will take too long and cost too much,” she said.

And it remains unclear whether drug companies will decide to stop pursuing novel agents if approvals will ultimately require more expensive and time-consuming trials.

According to Chaft, oncologists have been discussing protocols that could help fill the knowledge gaps. Such trials will be conducted by the National Cancer Institute’s Cooperative Groups, she noted. But it’s early days.

For the time being, with comparative data from phase 3 trials years away, oncologists will have to work with the limited evidence and individual patients in front of them.

Chaft disclosed ties with AstraZeneca, Boehringer Ingelheim, Bristol Myers Squibb, Genentech/Roche, Guardant Health, Janssen Pharmaceuticals, Eli Lilly, and Merck. Reuss disclosed ties with AstraZeneca, Arcus, AbbVie, Bristol Myers Squibb, CatalYm, Daiichi Sankyo, and Eli Lilly, and that Georgetown has received research funding from Genentech/Roche, Verastem, Nuvalent, LUNGevity Foundation, Exelixis, Arcus, and Revolution Medicines. Spratt disclosed ties with Astellas, AstraZeneca, Bayer, Boston Scientific, Janssen Pharmaceuticals, Novartis, and Pfizer.

The cutting edge of treating solid tumors with cell therapies got notably sharper in 2024.

First came the US Food and Drug Administration (FDA) approval in February 2024 of the tumor-infiltrating lymphocyte (TIL) therapy lifileucel in unresectable or metastatic melanoma that had progressed on prior immunotherapy, the first cellular therapy for any solid tumor. Then came the August FDA approval of afamitresgene autoleucel in unresectable or metastatic synovial sarcoma with failed chemotherapy, the first engineered T-cell therapy for cancers in soft tissue. 

“This was a pipe dream just a decade ago,” Alison Betof Warner, MD, PhD, lead author of a lifileucel study (NCT05640193), said in an interview with Medscape Medical News. “At the start of 2024, we had no approvals of these kinds of products in solid cancers. Now we have two.”

As the director of Solid Tumor Cell Therapy and leader of Stanford Medicine’s Melanoma and Cutaneous Oncology Clinical Research Group, Betof Warner has been at the forefront of developing commercial cell therapy using tumor-infiltrating lymphocytes (TILs). 

“The approval of lifileucel increases confidence that we can get these therapies across the regulatory finish line and to patients,” Betof Warner said during the interview. She was not involved in the development of afamitresgene autoleucel.

 

‘Reverse Engineering’

In addition to her contributions to the work that led to lifileucel’s approval, Betof Warner was the lead author on the first consensus guidelines on management and best practices for tumor-infiltrating lymphocyte cell therapy. 

Betof Warner began studying TILs after doing research with her mentors in immuno-oncology, Jedd D. Wolchok and Michael A. Postow. Their investigations — including one that Betof Warner coauthored — into how monoclonal antibodies and checkpoint inhibitors, such as ipilimumab or nivolumab, might extend the lives of people with advanced unresectable or metastatic melanoma inspired her to push further to find ways to minimize treatment while maximizing outcomes for patients. Betof Warner’s interest overall, she said in the interview, is in capitalizing on what can be learned about how the immune system controls cancer.

“What we know is that the immune system has the ability to kill cancer,” Betof Warner said. “Therefore we need to be thinking about how we can increase immune surveillance. How can we enhance that before a patient develops advanced cancer? 

Betof Warner said that although TILs are now standard treatment in melanoma, there is about a 30% response rate compared with about a 50% response rate in immunotherapy, and the latter is easier for the patient to withstand. 

“Antibodies on the frontline are better than going through a surgery and then waiting weeks to get your therapy,” Betof Warner said in the interview. “You can come into my clinic and get an antibody therapy in 30 minutes and go straight to work. TILs require patients to be in the hospital for weeks at a time and out of work for months at a time.”

In an effort to combine therapies to maximize best outcomes, a phase 3 trial (NCT05727904) is currently recruiting. The TILVANCE-301 trial will compare immunotherapy plus adoptive cell therapy vs immunotherapy alone in untreated unresectable or metastatic melanoma. Betof Warner is not a part of this study.

 

Cell Therapies Include CAR T Cells and TCRT

In general, adoptive T-cell therapies such as TILs involve the isolation of autologous immune cells that are removed from the body and either expanded or modified to optimize their efficacy in fighting antigens, before their transfer to the patient as a living drug by infusion.

In addition to TILs, adoptive cell therapies for antitumor therapeutics include chimeric antigen receptor (CAR) T cells and engineered T-cell receptor therapy (TCRT).

In CAR T-cell therapy and TCRT, naive T cells are harvested from the patient’s blood then engineered to target a tumor. In TIL therapy, tumor-specific T cells are taken from the patient’s tumor. Once extracted, the respective cells are expanded billions of times and then delivered back to the patient’s body, said Betof Warner. 

“The main promise of this approach is to generate responses in what we know as ‘cold’ tumors, or tumors that do not have a lot of endogenous T-cell infiltration or where the T cells are not working well, to bring in tumor targeting T cells and then trigger an immune response,” Betof Warner told an audience at the American Society of Clinical Oncology (ASCO) 2024 annual meeting.

TIL patients also receive interleukin (IL)-2 infusions to further stimulate the cells. In patients being treated with TCRT, they either receive low or no IL-2, Betof Warner said in her ASCO presentation, “Adopting Cutting-Edge Cell Therapies in Melanoma,” part of the session Beyond the Tip of the Iceberg: Next-Generation Cell-Based Therapies. 

Betof Warner takes Medscape Medical News through the history and ongoing investigations of cellular therapies for solid tumors, including her own research on these treatments. 

 

Decades in the Making

The National Cancer Institute began investigating TILs in the late 1980s, with the current National Cancer Institute (NCI) surgery chief, Steven Rosenberg, MD, PhD, leading the first-ever trials that showed TILs could shrink tumors in people with advanced melanoma.

Since then, NCI staff and others have also investigated TILs beyond melanoma and additional cell therapies based on CAR T cells and TCRT for antitumor therapeutics. 

“TCRs are different from CAR Ts because they go after intracellular antigens instead of extracellular antigens,” said Betof Warner. “That has appeal because many of the tumor antigens we’re looking for will be intracellular.” 

Because CAR T cells only target extracellular antigens, their utility is somewhat limited. Although several CAR T-cell therapies exist for blood cancers, there currently are no approved CAR T-cell therapies for solid tumors. However, several trials of CAR T cells in gastrointestinal cancers and melanoma are ongoing, said Betof Warner, who is not a part of these studies.

“We are starting to see early-phase efficacy in pediatric gliomas,” Betof Warner said, mentioning a study conducted by colleagues at Stanford who demonstrated potential for anti-GD2 CAR T-cell therapy in deadly pediatric diffuse midline gliomas, tumors on the spine and brain.

In their study, nine out of 11 participants (median age, 15 years) showed benefit from the cell therapy, with one participant’s tumors resolving completely. The results paved the way for the FDA to grant a Regenerative Medicine Advanced Therapy designation for use of anti-GD2 CAR T cells in H3K27M-positive diffuse midline gliomas. 

The investigators are now recruiting for a phase 1 trial (NCT04196413). Results of the initial study were published in Nature last month.

Another lesser-known cell therapy expected to advance at some point in the future for solid tumors is use of the body’s natural killer (NK) cells. “They’ve been known about for a long time, but they are more difficult to regulate, which is one reason why it has taken longer to make NK cell therapies,” said Betof Warner, who is not involved in the study of NK cells. “One of their advantages is that, potentially, there could be an ‘off the shelf’ NK product. They don’t necessarily have to be made with autologous cells.”

 

Risk-Benefit Profiles Depend on Mechanism of Action

If the corresponding TCR sequence of a tumor antigen is known, said Betof Warner, it is possible to use leukapheresis to generate naive circulating lymphocytes. Once infused, the manufactured TCRTs will activate in the body the same as native cells because the signaling is the same.
An advantage to TCRT compared with CAR T-cell therapy is that it targets intracellular proteins, which are significantly present in the tumor, Betof Warner said in her presentation at ASCO 2024. She clarified that tumors will usually be screened for the presence of this antigen before a patient is selected for treatment with that particular therapy, because not all antigens are highly expressed in every tumor. 

“Furthermore, the tumor antigen has to be presented by a major histocompatibility complex, meaning there are human leukocyte antigen restrictions, which impacts patient selection,” she said.

A risk with both TCRT and CAR T-cell therapy, according to Betof Warner, is that because there are often shared antigens between tumor and normal tissues, on-target/off-tumor toxicity is a risk.

“TILs are different because they are nonengineered, at least not for antigen recognition. They are polyclonal and go after multiple targets,” Betof Warner said. “TCRs and CARs are engineered to go after one target. So, TILs have much lower rates of on-tumor/off-target effects, vs when you engineer a very high affinity receptor like a TCR or CAR.”

A good example of how this amplification of TCR affinity can lead to poor outcomes is in metastatic melanoma, said Betof Warner. 

In investigations (NCI-07-C-0174 and NCI-07-C-0175) of TCRT in metastatic melanoma, for example, the researchers were targeting MART-1 or gp100, which are expressed in melanocytes. 

“The problem was that these antigens are also expressed in the eyes and ears, so it caused eye inflammation and hearing loss in a number of patients because it wasn’t specific enough for the tumor,” said Betof Warner. “So, if that target is highly expressed on normal tissue, then you have a high risk.”

 

Promise of PRAME

Betof Warner said the most promising TCRT at present is the investigational autologous cell therapy IMA203 (NCT03688124), which targets the preferentially expressed antigen (PRAME). Although PRAME is found in many tumors, this testis antigen does not tend to express in normal, healthy adult tissues. Betof Warner is not affiliated with this study. 

“It’s maybe the most exciting TCRT cell in melanoma,” Betof Warner told her audience at the ASCO 2024 meeting. Because the expression rate of PRAME in cutaneous and uveal melanoma is at or above 95% and 90%, respectively, she said “it is a really good target in melanoma.”

Phase 1a results reported in late 2023 from a first-in-human trial of IMA203 involving 13 persons with highly advanced melanoma and a median of 5.5 previous treatments showed a 50% objective response rate in the 12 evaluable results. The duration of response ranged between 2.2 and 14.7 months (median follow-up, 14 months).

The safety profile of the treatment was favorable, with no grade 3 adverse events occurring in more than 10% of the cohort, and no grade 5 adverse events at all.

Phase 1b results published in October by maker Immatics showed that in 28 heavily pretreated metastatic melanoma patients, IMA203 had a confirmed objective response rate of 54% with a median duration of response of 12.1 months, while maintaining a favorable tolerability profile. 

 

Accelerated Approvals, Boxed Warnings

The FDA granted accelerated approvals for both lifileucel, the TIL therapy, and afamitresgene autoleucel, the TCRT. 

Both were approved with boxed warnings. Lifileucel’s warning is for treatment-related mortality, prolonged severe cytopenia, severe infection, and cardiopulmonary and renal impairment. Afamitresgene autoleucel’s boxed warning is for serious or fatal cytokine release syndrome, which may be severe or life-threatening.

With these approvals, the bar is now raised on TILs and TCRTs, said Betof Warner.

The lifileucel trial studied 73 patients whose melanoma had continued to metastasize despite treatment with a programmed cell death protein (PD-1)/ programmed death-ligand (PD-L1)–targeted immune checkpoint inhibitor and a BRAF inhibitor (if appropriate based on tumor mutation status), and whose lifileucel dose was at least 7.5 billion cells (the approved dose). The cohort also received a median of six IL-2 (aldesleukin) doses. 

The objective response rate was 31.5% (95% CI, 21.1-43.4), and median duration of response was not reached (lower bound of 95% CI, 4.1).

In the afamitresgene autoleucel study, 44 of 52 patients with synovial sarcoma received leukapheresis and a single infusion of afamitresgene autoleucel. 

The overall response rate was 43.2% (95% CI, 28.4-59.0). The median time to response was 4.9 weeks (95% CI, 4.4-8), and the median duration of response was 6 months (lower bound of 95% CI, 4.6). Among patients who were responsive to the treatment, 45.6% and 39.0% had a duration of response of 6 months or longer and 12 months or longer, respectively.

 

New Hope for Patients

Betof Warner and her colleagues are now recruiting for an open-label, phase 1/2 investigation of the safety and efficacy of the TIL therapy OBX-115 in adult advanced solid tumors in melanoma or non–small cell lung cancer. The first-in-human results of a previous trial were presented at the ASCO 2024 meeting, and OBX-115 received FDA fast track designation in July.

“I think the results are really promising,” said Betof Warner. “This is an engineered TIL that does not require administering IL-2 to the patient. There were four out of the nine patients who responded to the treatment and there were no dose-limiting toxicities, no cytokine and no intracranial — all of which is excellent.”

For Betof Warner, the possibility that by using their own immune system, patients with advanced and refractory cancers could soon have a one-time treatment with a cell therapy rather than innumerable bouts of chemotherapy pushes her onward.

“The idea that we can treat cancer one time and have it not recur for years — that’s pushing the start of saying there’s a cure of cancer. That a person could move on from cancer like they move on from an infection. That is the potential of this work. We’re not there yet, but that’s where we need to think and dream big,” she said.

Betof Warner disclosed consulting/advisory roles with BluePath Solutions, Bristol-Myers Squibb/Medarex, Immatics, Instil Bio, Iovance Biotherapeutics, Lyell Immunopharma, Merck, Novartis, and Pfizer and research funding and travel expenses from Iovance Biotherapeutics.

The cutting edge of treating solid tumors with cell therapies got notably sharper in 2024.

First came the US Food and Drug Administration (FDA) approval in February 2024 of the tumor-infiltrating lymphocyte (TIL) therapy lifileucel in unresectable or metastatic melanoma that had progressed on prior immunotherapy, the first cellular therapy for any solid tumor. Then came the August FDA approval of afamitresgene autoleucel in unresectable or metastatic synovial sarcoma with failed chemotherapy, the first engineered T-cell therapy for cancers in soft tissue. 

“This was a pipe dream just a decade ago,” Alison Betof Warner, MD, PhD, lead author of a lifileucel study (NCT05640193), said in an interview with Medscape Medical News. “At the start of 2024, we had no approvals of these kinds of products in solid cancers. Now we have two.”

As the director of Solid Tumor Cell Therapy and leader of Stanford Medicine’s Melanoma and Cutaneous Oncology Clinical Research Group, Betof Warner has been at the forefront of developing commercial cell therapy using tumor-infiltrating lymphocytes (TILs). 

“The approval of lifileucel increases confidence that we can get these therapies across the regulatory finish line and to patients,” Betof Warner said during the interview. She was not involved in the development of afamitresgene autoleucel.

 

‘Reverse Engineering’

In addition to her contributions to the work that led to lifileucel’s approval, Betof Warner was the lead author on the first consensus guidelines on management and best practices for tumor-infiltrating lymphocyte cell therapy. 

Betof Warner began studying TILs after doing research with her mentors in immuno-oncology, Jedd D. Wolchok and Michael A. Postow. Their investigations — including one that Betof Warner coauthored — into how monoclonal antibodies and checkpoint inhibitors, such as ipilimumab or nivolumab, might extend the lives of people with advanced unresectable or metastatic melanoma inspired her to push further to find ways to minimize treatment while maximizing outcomes for patients. Betof Warner’s interest overall, she said in the interview, is in capitalizing on what can be learned about how the immune system controls cancer.

“What we know is that the immune system has the ability to kill cancer,” Betof Warner said. “Therefore we need to be thinking about how we can increase immune surveillance. How can we enhance that before a patient develops advanced cancer? 

Betof Warner said that although TILs are now standard treatment in melanoma, there is about a 30% response rate compared with about a 50% response rate in immunotherapy, and the latter is easier for the patient to withstand. 

“Antibodies on the frontline are better than going through a surgery and then waiting weeks to get your therapy,” Betof Warner said in the interview. “You can come into my clinic and get an antibody therapy in 30 minutes and go straight to work. TILs require patients to be in the hospital for weeks at a time and out of work for months at a time.”

In an effort to combine therapies to maximize best outcomes, a phase 3 trial (NCT05727904) is currently recruiting. The TILVANCE-301 trial will compare immunotherapy plus adoptive cell therapy vs immunotherapy alone in untreated unresectable or metastatic melanoma. Betof Warner is not a part of this study.

 

Cell Therapies Include CAR T Cells and TCRT

In general, adoptive T-cell therapies such as TILs involve the isolation of autologous immune cells that are removed from the body and either expanded or modified to optimize their efficacy in fighting antigens, before their transfer to the patient as a living drug by infusion.

In addition to TILs, adoptive cell therapies for antitumor therapeutics include chimeric antigen receptor (CAR) T cells and engineered T-cell receptor therapy (TCRT).

In CAR T-cell therapy and TCRT, naive T cells are harvested from the patient’s blood then engineered to target a tumor. In TIL therapy, tumor-specific T cells are taken from the patient’s tumor. Once extracted, the respective cells are expanded billions of times and then delivered back to the patient’s body, said Betof Warner. 

“The main promise of this approach is to generate responses in what we know as ‘cold’ tumors, or tumors that do not have a lot of endogenous T-cell infiltration or where the T cells are not working well, to bring in tumor targeting T cells and then trigger an immune response,” Betof Warner told an audience at the American Society of Clinical Oncology (ASCO) 2024 annual meeting.

TIL patients also receive interleukin (IL)-2 infusions to further stimulate the cells. In patients being treated with TCRT, they either receive low or no IL-2, Betof Warner said in her ASCO presentation, “Adopting Cutting-Edge Cell Therapies in Melanoma,” part of the session Beyond the Tip of the Iceberg: Next-Generation Cell-Based Therapies. 

Betof Warner takes Medscape Medical News through the history and ongoing investigations of cellular therapies for solid tumors, including her own research on these treatments. 

 

Decades in the Making

The National Cancer Institute began investigating TILs in the late 1980s, with the current National Cancer Institute (NCI) surgery chief, Steven Rosenberg, MD, PhD, leading the first-ever trials that showed TILs could shrink tumors in people with advanced melanoma.

Since then, NCI staff and others have also investigated TILs beyond melanoma and additional cell therapies based on CAR T cells and TCRT for antitumor therapeutics. 

“TCRs are different from CAR Ts because they go after intracellular antigens instead of extracellular antigens,” said Betof Warner. “That has appeal because many of the tumor antigens we’re looking for will be intracellular.” 

Because CAR T cells only target extracellular antigens, their utility is somewhat limited. Although several CAR T-cell therapies exist for blood cancers, there currently are no approved CAR T-cell therapies for solid tumors. However, several trials of CAR T cells in gastrointestinal cancers and melanoma are ongoing, said Betof Warner, who is not a part of these studies.

“We are starting to see early-phase efficacy in pediatric gliomas,” Betof Warner said, mentioning a study conducted by colleagues at Stanford who demonstrated potential for anti-GD2 CAR T-cell therapy in deadly pediatric diffuse midline gliomas, tumors on the spine and brain.

In their study, nine out of 11 participants (median age, 15 years) showed benefit from the cell therapy, with one participant’s tumors resolving completely. The results paved the way for the FDA to grant a Regenerative Medicine Advanced Therapy designation for use of anti-GD2 CAR T cells in H3K27M-positive diffuse midline gliomas. 

The investigators are now recruiting for a phase 1 trial (NCT04196413). Results of the initial study were published in Nature last month.

Another lesser-known cell therapy expected to advance at some point in the future for solid tumors is use of the body’s natural killer (NK) cells. “They’ve been known about for a long time, but they are more difficult to regulate, which is one reason why it has taken longer to make NK cell therapies,” said Betof Warner, who is not involved in the study of NK cells. “One of their advantages is that, potentially, there could be an ‘off the shelf’ NK product. They don’t necessarily have to be made with autologous cells.”

 

Risk-Benefit Profiles Depend on Mechanism of Action

If the corresponding TCR sequence of a tumor antigen is known, said Betof Warner, it is possible to use leukapheresis to generate naive circulating lymphocytes. Once infused, the manufactured TCRTs will activate in the body the same as native cells because the signaling is the same.
An advantage to TCRT compared with CAR T-cell therapy is that it targets intracellular proteins, which are significantly present in the tumor, Betof Warner said in her presentation at ASCO 2024. She clarified that tumors will usually be screened for the presence of this antigen before a patient is selected for treatment with that particular therapy, because not all antigens are highly expressed in every tumor. 

“Furthermore, the tumor antigen has to be presented by a major histocompatibility complex, meaning there are human leukocyte antigen restrictions, which impacts patient selection,” she said.

A risk with both TCRT and CAR T-cell therapy, according to Betof Warner, is that because there are often shared antigens between tumor and normal tissues, on-target/off-tumor toxicity is a risk.

“TILs are different because they are nonengineered, at least not for antigen recognition. They are polyclonal and go after multiple targets,” Betof Warner said. “TCRs and CARs are engineered to go after one target. So, TILs have much lower rates of on-tumor/off-target effects, vs when you engineer a very high affinity receptor like a TCR or CAR.”

A good example of how this amplification of TCR affinity can lead to poor outcomes is in metastatic melanoma, said Betof Warner. 

In investigations (NCI-07-C-0174 and NCI-07-C-0175) of TCRT in metastatic melanoma, for example, the researchers were targeting MART-1 or gp100, which are expressed in melanocytes. 

“The problem was that these antigens are also expressed in the eyes and ears, so it caused eye inflammation and hearing loss in a number of patients because it wasn’t specific enough for the tumor,” said Betof Warner. “So, if that target is highly expressed on normal tissue, then you have a high risk.”

Betof Warner said the most promising TCRT at present is the investigational autologous cell therapy IMA203 (NCT03688124), which targets the preferentially expressed antigen (PRAME). Although PRAME is found in many tumors, this testis antigen does not tend to express in normal, healthy adult tissues. Betof Warner is not affiliated with this study.

The FDA granted accelerated approvals for both lifileucel, the TIL therapy, and afamitresgene autoleucel, the TCRT. 

Both were approved with boxed warnings. Lifileucel’s warning is for treatment-related mortality, prolonged severe cytopenia, severe infection, and cardiopulmonary and renal impairment. Afamitresgene autoleucel’s boxed warning is for serious or fatal cytokine release syndrome, which may be severe or life-threatening.

With these approvals, the bar is now raised on TILs and TCRTs, said Betof Warner.

The cohort also received a median of six IL-2 (aldesleukin) doses. 

The objective response rate was 31.5% (95% CI, 21.1-43.4), and median duration of response was not reached (lower bound of 95% CI, 4.1).

In the afamitresgene autoleucel study, 44 of 52 patients with synovial sarcoma received leukapheresis and a single infusion of afamitresgene autoleucel. 

The overall response rate was 43.2% (95% CI, 28.4-59.0). The median time to response was 4.9 weeks (95% CI, 4.4-8), and the median duration of response was 6 months (lower bound of 95% CI, 4.6). Among patients who were responsive to the treatment, 45.6% and 39.0% had a duration of response of 6 months or longer and 12 months or longer, respectively.

Betof Warner and her colleagues are now recruiting for an open-label, phase 1/2 investigation of the safety and efficacy of the TIL therapy OBX-115 in adult advanced solid tumors in melanoma or non–small cell lung cancer.

For over 200 years, researchers have been captivated by axolotl salamanders (Ambystoma mexicanum) and their remarkable regenerative abilities, seeking to uncover secrets that could revolutionize regenerative medicine, including the scarless healing of wounds.

“The axolotl salamander is the most studied animal ever in science for its neotenic ability to regenerate,” Jill S. Waibel, MD, dermatologist and researcher in Miami, Florida, said in an interview. Neotenic tissue retains a juvenile or immature state throughout an organism’s life. In the case of the axolotl, “it can regenerate limbs, part of its heart, even its brain.”

 

A 2019 review of several studies on the regenerative abilities of axolotls highlights the importance of gene activity in controlling its skin regeneration. Specifically, growth factors such as fibroblast growth factors, transforming growth factor beta, and Wnt play a key role in guiding how the creature’s skin cells behave during healing and regrowth. The immune response , particularly the actions of macrophages and neutrophils, is also crucial in the early stages of regeneration, as these cells clear away dead tissue and kickstart the healing process.

After studying the axolotl for the past 8 years, including mapping its genetic makeup, Waibel and researchers at RegenX Science are developing a line of cosmeceutical and over-the-counter products containing urodele collagen extract derived from the creature’s neotenic tissue, without harming the animal. In axolotls, Waibel explained, damaged neotenic tissue “still thinks it’s in fetal mode, so if it injures its muscle, bone, nerves, collagen, or skin, everything will redevelop. After a few months in utero, that process stops in humans, but it never stops in the axolotl. The axolotl has scarless healing and immunity because of antimicrobial properties found in the neotenic tissue.”

RegenX scientists have developed a proprietary decellularization process that renders the urodele collagen extract safe and effective for use in humans. “We then harnessed a reservoir of bioactive peptides, which are small proteins that come from the axolotl, but they don’t contain any RNA or DNA that could confer the risk of any diseases or cancer,” she added.

According to Waibel, who is also subsection chief of dermatology at Baptist Hospital and past medical director of the Miami Cancer Institute’s Multidisciplinary Skin Cancer Clinic, genetic analysis of the axolotl revealed genes that have not been seen in humans. The urodele collagen extract also has anti-inflammatory and analgesic properties. “It decreases TNF [tumor necrosis factor] and IL [interleukin]–23 and stimulates regenerative pathways like FETUB (Fetuin-B), which is a gene involved in tissue regeneration,” she said. “We’re exploring these for some products.”

Institutional Review Board–approved human clinical trials at three US sites are nearly complete for evaluating an antiaging hydrating daily serum, an antiaging serum for damaged skin, and a restorative serum to be applied following cosmetic procedures, all containing the extract. The product furthest along is a “super gel” that contains properties of the urodele collagen extract.

In a proof-of-concept study using a third-degree burn model in two pigs, Waibel and colleagues at the University of Miami, found that 3 days after the injury was induced, application of the gel led to 92% reepithelialization of the pig’s skin, compared with only 54% in untreated skin.

Shortly after this study was conducted, a burn patient was referred to Waibel — 4 years after he was struck by lightning while fishing on a boat in Mississippi, an accident that resulted in the loss of his right arm and both legs. During a telemedicine consultation, Waibel noticed open ulcers on his chest. “What are those from?” she asked. “They’re from my accident 4 years ago,” he replied. 

After the man flew to Miami for an in-person evaluation, Waibel treated his ulcers with a fractional laser to debride the wound, then applied the gel as part of a proof-of-concept approach, testing its potential in a real-world patient setting. Within 3 weeks, the long-standing ulcerated area had healed completely, marking the first time a human was treated with the super gel.

Looking ahead, the million-dollar question, Waibel noted, is how much healing can be achieved in humans with formulations of axolotl-derived technology. “For example, can we help a spinal cord injury patient? That sounds like a science fiction movie, but there are proteins in genes in this animal that we have turned off that potentially can be turned on in a human,” she said. “It’s very exciting.”

 

Arisa E. Ortiz, MD, director of Laser and Cosmetic Dermatology at the University of California, San Diego, and current president of the American Society for Laser Medicine and Surgery, who was asked to comment on this work, said that the use of urodele collagen extract derived from axolotl tissue “is an exciting innovation, especially given its unique properties like scarless healing and antimicrobial activity.” 

While the results from preclinical and proof-of-concept studies are promising, “a key limitation lies in understanding the extent to which these findings will translate to human applications,” Ortiz said. “Overall, this research contributes significantly to the fields of regenerative medicine and dermatology, offering hope for more effective treatments in the future.” 

 

Christine Ko, MD, professor of dermatology and pathology at Yale University, New Haven, Connecticut, who was also asked to provide her insights on the topic, said that, if researchers could replicate the axolotl salamander’s ability to regenerate its own limbs and organs, “medicine would be transformed. Rather than transplant another person’s organ with lifelong immunosuppression, a regenerative treatment could program a patient’s own body to create a needed organ. 

“On a simpler level,” she continued, “regenerating skin and its underlying structures could hasten wound healing and potentially even treat hair loss. This is not a pipe dream, as Waibel has successfully treated severe ulcers using a super gel containing urodele collagen extract. Urodele collagen is type XII collagen, important in the salamander’s capacity to heal and regenerate.”

Waibel disclosed that she is a scientific adviser to RegenX and is a member of the company’s board of directors. Ortiz and Ko reported having no relevant disclosures.

What current events are keeping Americans up at night? The economy, gun violence, and hate crimes top the list, results from a newly released American Psychiatric Association (APA) survey showed.

Anxiety about international conflicts — namely, the Russia-Ukraine and Israel-Hamas wars — also remains high.

“While we like to stay informed, the news can also impact our mental health, and being mindful of that impact is important. If current events seem overwhelming it may be time to limit your news consumption,” APA CEO and Medical Director Marketa M. Wills, MD, MBD, said in a statement.

Survey results also revealed the election and the holidays were common sources of stress.

“Election stress is common, and it’s important to recognize that, as we’re spending more time with family around the holidays, we might need to have a strategy to manage our own mental health during these times,” Howard Liu, MD, MBA, chair of the Department of Psychiatry, University of Nebraska Medical Center, Omaha, told this news organization.

“As with any difficult topic, we all have different levels of avoidance or desire to engage, and it’s okay to set boundaries based on past conversations with family. I think sometimes we get drawn into arguments that we don’t want to have or may not be productive for either side,” said Liu, who chairs the APA Council on Communications.

In line with trends throughout 2024, adults polled by the APA in November were most anxious about the economy (75%), gun violence (64%), and hate crimes (60%). The survey included 2200 US adults as part of the APA’s Healthy Minds monthly series.

Anxiety about international conflicts remained high in November at 57% — but was down from 65% in August.

Election anxiety remained high in mid-November but not as high as before the election. In August, 72% of Americans said they were anxious about the 2024 election. In November, just after the election, 50% reported anxiety over the election outcome.

“I think the anticipation of change can sometimes be worse than the change itself. So I think a lot of people are now taking the attitude of — let’s wait and see what actually happens,” said Liu.

Half the adults (50%) anticipate the same amount of stress as the 2023 holiday season, while almost one third expect more stress (28%), and one fourth anticipate less stress (23%).

When asked how the holidays generally affect their mental health, 38% said it has positive effects, and 21% said the opposite was true.

 

Anxiety About the Future

After a divisive election, most Americans were ready to avoid politics at holiday gatherings, results of a separate poll conducted by the American Psychological Association in late November showed.

That poll, which included 2000 US adults, showed that more than 7 in 10 (72%) said they wanted to avoid talking about politics with family and friends over the holidays.

In addition, nearly two in five adults (39%) reported they were stressed by the thought of politics being raised at holiday gatherings and would try to avoid family members they disagree with. Younger adults were significantly more likely than were their older counterparts to report they planned to avoid family over the holidays.

The future of the nation also weighs on the minds of many Americans.

Another poll conducted by the American Psychological Association in August prior to the 2024 US presidential election showed that 77% of respondents said the future of the nation was a significant source of stress for them.

In the postelection poll, more than one third of adults (35%) said they are more stressed about the future of the nation now than they were leading up to the election, and another third reported they are now less stressed (32%). A quarter of adults (24%) said their stress about the future of the nation was unchanged, and 9% said they were not stressed about the future of the nation then or now.

“There’s still clearly a lot of uncertainty, and there’s a lot of activity right now for the president-elect,” which can contribute to anxiety, C. Vaile Wright, PhD, psychologist, researcher and spokesperson for the American Psychological Association, told this news organization.

These data also show that many Americans have little or no trust in the government, with some wanting to leave the United States.

“It’s a reflection of the lack of strong leadership across the board in this country. We have a governmental system in place that does not seem to serve the people, but to serve corporations and maintenance of power. I think people are disillusioned with it and that creates a lack of trust and hopelessness,” Wright noted.

Liu and Wright reported no relevant disclosures.

More than two thirds of American counties don’t have an endocrinologist, according to a new analysis by GoodRx, a company that provides discount coupons for medications.

A total of 50 million people who live in the 2168 counties without a practicing endocrinologist are at a higher risk for poor health outcomes, according to the analysis. 

The author reported that individuals who live in endocrinology “deserts” are 12% more likely to die from endocrine-related conditions and have higher rates of diabetes, obesity, and stroke than those who live in counties where there are endocrinologists.

GoodRx’s finely detailed maps show that endocrinologists are clustered on the coasts and around major cities. Many counties have just a single endocrinologist and no pediatric endocrinologists.

Endocrinologists are not flocking to areas with a high type 2 diabetes prevalence — such as southern states, many parts of Texas, and counties with high concentrations of Native Americans or Alaskan Natives.

The maps speak volumes about disparities. In Sabine Parish, Louisiana, which shares a border with east Texas, the adult diabetes prevalence is 14%. The age-adjusted diabetes death rate is 52.6 per 100,000, in a population of 16,936 adults. There are no endocrinologists in that parish and one in a bordering parish.

In the entire state of Alaska, there are a total of two adult endocrinologists — one in Anchorage County and one in Fairbanks County — and two pediatric endocrinologists, both in Anchorage.

Buffalo County, South Dakota, which has no endocrinologists and is dominated by the Crow Creek Reservation, has a diabetes prevalence of 16.6% and a diabetes death rate of 143.3 per 100,000.

Connecticut’s Hartford County, however, has 69 adult endocrinologists and 9 pediatric endocrinologists. The adult diabetes prevalence is 0%, and the death rate is 26.3 per 100,000, in a population of 896,854.

To come up with its maps, GoodRx used population estimates from the 2024 Centers for Disease Control and Prevention (CDC) Places dataset and calculated adult diabetes rates and age-adjusted diabetes-related death rates per 100,000 using the 2024 CDC Places and CDC Wonder datasets. Data on the number of practicing endocrinologists came from HealthLink Dimensions, a company that provides databases for marketing purposes.

Robert Lash, MD, chief medical officer for The Endocrine Society, said that the GoodRx data are not especially new. Endocrinology “deserts” have existed for a decade or more, Lash said.

The GoodRx analysis concluded that a lack of endocrinologists in the “desert” counties directly led to higher death rates in those areas. “This is much more an association that it is causation,” countered Lash, noting that the deserts tend to align with healthcare professional shortage areas.

GoodRx also acknowledged the overlap and said that it could mean less access to primary care. In turn, “many patients may not even receive a diagnosis for endocrine-related conditions, let alone the specialized care they need,” wrote the analyst. “Preventable conditions like diabetes spiral into severe complications.”

Lash said seeking out a primary care doctor is one option for those without access to an endocrinologist. Telemedicine has also helped expand access, said Lash, adding that endocrinologists have been among the more frequent users.

Even so, the shortage of endocrinologists is an ongoing problem, he said. Only about 5000-6000 endocrinologists are actively practicing, estimates The Endocrine Society.

Fewer medical school graduates are choosing endocrinology, in part because of the lack of compensation, said Lash.

The society has begun a push to interest more students. Starting in 2024, The Society awarded grants to 10 medical schools to start endocrinology interest groups. The Medical School Engagement Program also sponsors two students for a VIP-type experience at the annual scientific meeting.

The hope is to boost interest in fellowships, which come after 3 years of internal medicine residency. Currently, there are only about 11 applicants for every 10 fellowship spots, said Lash.

It may be a while before the society’s experiment bears fruit. Those entering medical school in 2024 would not be eligible for fellowship until 2031, noted Lash.

“We’re in this for the long haul,” he said. “We know that this problem is not going to get solved overnight.”

More than two thirds of American counties don’t have an endocrinologist, according to a new analysis by GoodRx, a company that provides discount coupons for medications.

A total of 50 million people who live in the 2168 counties without a practicing endocrinologist are at a higher risk for poor health outcomes, according to the analysis. 

The author reported that individuals who live in endocrinology “deserts” are 12% more likely to die from endocrine-related conditions and have higher rates of diabetes, obesity, and stroke than those who live in counties where there are endocrinologists.

GoodRx’s finely detailed maps show that endocrinologists are clustered on the coasts and around major cities. Many counties have just a single endocrinologist and no pediatric endocrinologists.

Endocrinologists are not flocking to areas with a high type 2 diabetes prevalence — such as southern states, many parts of Texas, and counties with high concentrations of Native Americans or Alaskan Natives.

The maps speak volumes about disparities. In Sabine Parish, Louisiana, which shares a border with east Texas, the adult diabetes prevalence is 14%. The age-adjusted diabetes death rate is 52.6 per 100,000, in a population of 16,936 adults. There are no endocrinologists in that parish and one in a bordering parish.

In the entire state of Alaska, there are a total of two adult endocrinologists — one in Anchorage County and one in Fairbanks County — and two pediatric endocrinologists, both in Anchorage.

Buffalo County, South Dakota, which has no endocrinologists and is dominated by the Crow Creek Reservation, has a diabetes prevalence of 16.6% and a diabetes death rate of 143.3 per 100,000.

Connecticut’s Hartford County, however, has 69 adult endocrinologists and 9 pediatric endocrinologists. The adult diabetes prevalence is 0%, and the death rate is 26.3 per 100,000, in a population of 896,854.

To come up with its maps, GoodRx used population estimates from the 2024 Centers for Disease Control and Prevention (CDC) Places dataset and calculated adult diabetes rates and age-adjusted diabetes-related death rates per 100,000 using the 2024 CDC Places and CDC Wonder datasets. Data on the number of practicing endocrinologists came from HealthLink Dimensions, a company that provides databases for marketing purposes.

An individual’s estimated risk of having a heart attack or stroke in the next 10 years is widely used to guide preventative medication prescriptions with statins or antihypertensive drugs in those who have not yet had such an event.

To estimate that risk, doctors use equations that include different risk factors, such as age, cholesterol levels, and blood pressure. The current equations, known as the pooled cohort equations, are considered to be outdated as they were developed in 2013 based on population data from the 1960s and 70s. A new set of risk equations — known as the PREVENT equations — were developed by the American Heart Association (AHA) in 2023, and are based on a more contemporary population. It is anticipated that AHA will recommend these new risk equations be used in clinical practice in the next primary prevention guidelines.

But could these new risk equations do more harm than good?

Two recent studies found that applying the PREVENT risk equations to the US population results in a much lower overall level of risk compared with the pooled cohort equations. And, if the current threshold for starting statin treatment — which is an estimated 7.5% risk of having a heart attack or stroke in the next 10 years — is kept the same, this would result in many fewer patients being eligible for statin treatment.

As cardiovascular risk is also used to guide antihypertensive treatment, the new risk equations would also result in fewer people with borderline high blood pressure being eligible for those medications.

This has raised concerns in the medical community, where there is a widespread view that many more people would benefit from primary prevention treatment, and that anything that may cause fewer people to receive these medications would be harmful. 

“I believe the new equations more accurately predict the risk of the current US population, but we need to be aware of what effect that may have on use of statins,” said Tim Anderson, MD, who studies healthcare delivery at the University of Pittsburgh in Pennsylvania and is lead author of one of the studies evaluating the equations.

Anderson told this news organization that the pooled cohort equations have long been viewed as problematic. 

“Because these equations were based on cohorts from the 1960s and 70s, it is believed they overestimate the current population’s risk of MI and stroke as the burden of disease has shifted in the intervening 50-60 years,” he said.

 

Current Equations Overestimate Risk

The new equations are based on more recent, representative, and diverse cohorts that capture a wider spectrum of the population in terms of race, ethnicity, and socioeconomic status. They also include factors that are now known to be relevant to cardiovascular risk, such as chronic kidney disease.

Anderson compared how the two sets of equations estimated risk of cardiovascular disease in the next 10 years in the US population using the NHANES survey — a large nationally representative survey conducted between 2017 and 2020. 

He found that the pooled cohort equations estimated the population average 10-year risk of cardiovascular disease to be about 8%, but the PREVENT equations estimated it at just over 4%.

“The new equations estimate that the middle-aged US population have almost half the level of risk of MI and stroke over next 10 years compared with the equations used currently. So, we will substantially change risk estimates if the new equations are introduced into practice,” Anderson said. 

The study found that, if the PREVENT equations are adopted in the next set of primary prevention guidelines and the current threshold of a 7.5% risk of having an MI or stroke in the next 10 years is maintained as the starting point for statin treatment, then 17.3 million adults who were previously recommended primary prevention statin therapy would no longer be eligible.

A second, similar study, conducted by a different team of US researchers, estimated that using PREVENT would decrease the number of US adults receiving or recommended for statin therapy by 14.3 million and antihypertensive therapy by 2.62 million.

The researchers, led by James A. Diao, MD, from Harvard Medical School, Boston, Massachusetts, also suggested that over 10 years, reductions in treatment eligibility could result in an estimated 107,000 additional MI or stroke events.

Anderson points out that using the new equations would not affect the highest-risk patients. “They are still going to be high risk whichever equations are used. If you smoke a pack of cigarettes a day, have very high blood pressure or cholesterol and are older, then you are high risk. That part hasn’t changed. These people will qualify for statin treatment many times over with both sets of guidelines,” he said. 

Rather it will be the large population at moderate risk of cardiovascular disease that will be affected, with far fewer of these individuals likely to get statins.

“If you are on the fence about whether to take a statin or not and you’re currently just on the threshold where they might be recommended then these new equations could mean that you’ll be less likely to be offered them,” he said. “Using the new equations may result in a delay of a couple of years to have that conversation.”

 

A Red Flag

Steve Nissen, MD, a cardiologist at the Cleveland Clinic in Ohio, is not a fan of cardiovascular risk equations in general. He points out that less than half of those currently eligible for statins are actually treated. And he believes the studies suggesting fewer people will be eligible with the new risk equations raise a red flag on whether they should be used.

“Anything that may result in fewer people being treated is a huge problem,” he told this news organization. “We have abundant evidence that we should be treating more people, not fewer people. Every study we have done has shown benefit with statins.”

The risk calculators were initially developed to limit use of statins and other medications to high-risk patients, he said, but now that we know more about safety of these drugs, it’s clear that the risks are almost nonexistent. 

“We really need something else to guide the prescription of statins,” said Nissen.

Nissen suggests the risk calculators and guidelines have resulted in undertreatment of the population because they lack nuance and put too much emphasis on age. We should be more interested in reducing the lifetime risk of cardiovascular events, he said. “Calculators don’t do a good job of that. Their time horizons are too short. Young people with a family history of cardiovascular disease may have a low 10-year risk on a risk calculator but their lifetime risk is elevated, and as such, they should be considered for statin treatment. We need to find a more nuanced approach to understanding the lifetime risk of individuals,” he said. 

Nissen said risk calculators can be useful in high-risk patients to help demonstrate their need for treatment. “I can show them the calculator and that they have a 20% chance of an event — that can help convince them to take a statin.” 

But at the lower end of the risk scale, “all it does is keep patients who should be getting treatment from having that treatment.”

Nissen said changing the risk calculator won’t affect how he treats patients. “I use judgment to decide who to treat based on scientific literature and the patient in front of me. We will engage in a discussion and make a shared decision on what is the best course of action. Calculators will never be a substitute for medical judgment,” he said.

 

Equations Don’t Decide

Sadiya Khan, MD, a cardiologist at Northwestern University, Evanston, Illinois, and lead author of the PREVENT equations, told this news organization that it is important to put this discussion into context.

“The two recent papers do a good job of describing differences in predictive risk between the two sets of equations but that’s where they stop,” she said. “The translation from that to the decision on who should or should not be on statins or other medications is a step too far.”

Clinical guidelines will need to be updated to take the PREVENT equations into account, as Khan argued in a JAMA editorial. So it is not clear whether the current 7.5% 10-year risk figure will remain the threshold to start treatment. Khan anticipates the guidelines committee will have to re-evaluate that threshold.

“The 7.5% risk threshold was advised in the 2013 guidelines, based on what we knew then about the balance between benefit and harm and with the knowledge that the risk equations overestimated risk,” she said. “We now have a lot more data on the safety of statin therapy. We see this frequently in preventive care. Treatments often becomes more widespread in time and use expands into lower-risk patients.”

She also pointed out that the current primary prevention guidelines encourage consideration of other factors, not just predictive risk scores, when thinking about starting statins, including very high LDL cholesterol, family history, and apo B and Lp(a) levels.

“The recommendation on who would qualify for statin therapy is not based on one number,” she said. “It is based on many considerations, including both qualitative and quantitative factors, and discussions between the patient and the doctor. It is not a straightforward yes or no based on a 7.5% risk threshold.”

The equations, she said, should only be viewed as the first step in the process, and she said she agrees with Nissen that when applying the equations, doctors need to use additional data from each individual patient to make a judgment. “Equations do not decide who gets treated. Clinical practice guidelines do that.” 

Khan also agreed with Nissen that more effort is needed to identify longer term cardiovascular risk in younger people, and so the PREVENT equations include 30-year risk estimates.

“I totally agree that we need to start earlier in having these prevention conversations. The PREVENT model starts at age 30 which is 10 years earlier than the pooled cohort equations and they add a 30-year time horizon as well as the 10-year period for these discussions on predicted risk estimates,” she said. “We need to make sure we are not missing risk in young adults just because we are waiting for them to get into some arbitrary age category.”

Khan says she believes that, used correctly, the new equations will not limit access to statins or other cardiovascular treatments. “Because they are a more accurate reflection of risk in the contemporary population, the new PREVENT equations should identify the correct patients to be treated, within the confines of knowing that no risk prediction equation is perfect,” she said. “And if everything else is considered as well, not just the numbers in the risk equations, it shouldn’t result in fewer patients being treated.”

Anderson reported receiving grants from the American Heart Association, the American College of Cardiology, and the US Deprescribing Research Network. Nissen is leading a development program for a nonprescription low dose of rosuvastatin. He is also involved in trials of a new cholesterol lowering drug, obicetrapib, and on trials on drugs that lower Lp(a). Khan reported receiving grants from the American Heart Association and National Heart, Lung, and Blood Institute.

The study found that, if the PREVENT equations are adopted in the next set of primary prevention guidelines and the current threshold of a 7.5% risk of having an MI or stroke in the next 10 years is maintained as the starting point for statin treatment, then 17.3 million adults who were previously recommended primary prevention statin therapy would no longer be eligible.

A second, similar study, conducted by a different team of US researchers, estimated that using PREVENT would decrease the number of US adults receiving or recommended for statin therapy by 14.3 million and antihypertensive therapy by 2.62 million.

The researchers, led by James A. Diao, MD, from Harvard Medical School, Boston, Massachusetts, also suggested that over 10 years, reductions in treatment eligibility could result in an estimated 107,000 additional MI or stroke events.

Anderson points out that using the new equations would not affect the highest-risk patients. “They are still going to be high risk whichever equations are used. If you smoke a pack of cigarettes a day, have very high blood pressure or cholesterol and are older, then you are high risk. That part hasn’t changed. These people will qualify for statin treatment many times over with both sets of guidelines,” he said. 

Rather it will be the large population at moderate risk of cardiovascular disease that will be affected, with far fewer of these individuals likely to get statins.

“If you are on the fence about whether to take a statin or not and you’re currently just on the threshold where they might be recommended then these new equations could mean that you’ll be less likely to be offered them,” he said. “Using the new equations may result in a delay of a couple of years to have that conversation.”

 

A Red Flag

Steve Nissen, MD, a cardiologist at the Cleveland Clinic in Ohio, is not a fan of cardiovascular risk equations in general. He points out that less than half of those currently eligible for statins are actually treated. And he believes the studies suggesting fewer people will be eligible with the new risk equations raise a red flag on whether they should be used.

“Anything that may result in fewer people being treated is a huge problem,” he told this news organization. “We have abundant evidence that we should be treating more people, not fewer people. Every study we have done has shown benefit with statins.”

The risk calculators were initially developed to limit use of statins and other medications to high-risk patients, he said, but now that we know more about safety of these drugs, it’s clear that the risks are almost nonexistent. 

“We really need something else to guide the prescription of statins,” said Nissen.

Nissen suggests the risk calculators and guidelines have resulted in undertreatment of the population because they lack nuance and put too much emphasis on age. We should be more interested in reducing the lifetime risk of cardiovascular events, he said. “Calculators don’t do a good job of that. Their time horizons are too short. Young people with a family history of cardiovascular disease may have a low 10-year risk on a risk calculator but their lifetime risk is elevated, and as such, they should be considered for statin treatment. We need to find a more nuanced approach to understanding the lifetime risk of individuals,” he said. 

Nissen said risk calculators can be useful in high-risk patients to help demonstrate their need for treatment. “I can show them the calculator and that they have a 20% chance of an event — that can help convince them to take a statin.” 

But at the lower end of the risk scale, “all it does is keep patients who should be getting treatment from having that treatment.”

Nissen said changing the risk calculator won’t affect how he treats patients. “I use judgment to decide who to treat based on scientific literature and the patient in front of me. We will engage in a discussion and make a shared decision on what is the best course of action. Calculators will never be a substitute for medical judgment,” he said.

 

Equations Don’t Decide

Sadiya Khan, MD, a cardiologist at Northwestern University, Evanston, Illinois, and lead author of the PREVENT equations, told this news organization that it is important to put this discussion into context.

“The two recent papers do a good job of describing differences in predictive risk between the two sets of equations but that’s where they stop,” she said. “The translation from that to the decision on who should or should not be on statins or other medications is a step too far.”

Clinical guidelines will need to be updated to take the PREVENT equations into account, as Khan argued in a JAMA editorial. So it is not clear whether the current 7.5% 10-year risk figure will remain the threshold to start treatment. Khan anticipates the guidelines committee will have to re-evaluate that threshold.

“The 7.5% risk threshold was advised in the 2013 guidelines, based on what we knew then about the balance between benefit and harm and with the knowledge that the risk equations overestimated risk,” she said. “We now have a lot more data on the safety of statin therapy. We see this frequently in preventive care. Treatments often becomes more widespread in time and use expands into lower-risk patients.”

She also pointed out that the current primary prevention guidelines encourage consideration of other factors, not just predictive risk scores, when thinking about starting statins, including very high LDL cholesterol, family history, and apo B and Lp(a) levels.

“The recommendation on who would qualify for statin therapy is not based on one number,” she said. “It is based on many considerations, including both qualitative and quantitative factors, and discussions between the patient and the doctor. It is not a straightforward yes or no based on a 7.5% risk threshold.”

The equations, she said, should only be viewed as the first step in the process, and she said she agrees with Nissen that when applying the equations, doctors need to use additional data from each individual patient to make a judgment. “Equations do not decide who gets treated. Clinical practice guidelines do that.” 

Khan also agreed with Nissen that more effort is needed to identify longer term cardiovascular risk in younger people, and so the PREVENT equations include 30-year risk estimates.

“I totally agree that we need to start earlier in having these prevention conversations. The PREVENT model starts at age 30 which is 10 years earlier than the pooled cohort equations and they add a 30-year time horizon as well as the 10-year period for these discussions on predicted risk estimates,” she said. “We need to make sure we are not missing risk in young adults just because we are waiting for them to get into some arbitrary age category.”

Khan says she believes that, used correctly, the new equations will not limit access to statins or other cardiovascular treatments. “Because they are a more accurate reflection of risk in the contemporary population, the new PREVENT equations should identify the correct patients to be treated, within the confines of knowing that no risk prediction equation is perfect,” she said. “And if everything else is considered as well, not just the numbers in the risk equations, it shouldn’t result in fewer patients being treated.”

Anderson reported receiving grants from the American Heart Association, the American College of Cardiology, and the US Deprescribing Research Network. Nissen is leading a development program for a nonprescription low dose of rosuvastatin. He is also involved in trials of a new cholesterol lowering drug, obicetrapib, and on trials on drugs that lower Lp(a). Khan reported receiving grants from the American Heart Association and National Heart, Lung, and Blood Institute.

Laura Vater remembers sneaking into her home after 12-hour night shifts during medical training while her husband distracted their toddler. The stealthy tag-teaming effort helped her get enough undisturbed sleep before returning to an Indiana University hospital the following night to repeat the pattern.

“He would pretend to take out the trash when I pulled in,” said Vater, MD, now a gastrointestinal oncologist and assistant professor of medicine at IU Health Simon Cancer Center in Indianapolis. “I would sneak in so she [their daughter] wouldn’t see me, and then he would go back in.”

For Vater, prioritizing sleep during the day to combat sleep deprivation common among doctors-in-training on night shifts required enlisting a supportive spouse. It’s just one of the tips she and a few chief residents shared with this news organization for staying sharp and healthy during overnight rotations.

While the pace of patient rounds may slow from the frenetic daytime rush, training as a doctor after the sun goes down can be quite challenging for residents, they told this news organization. From sleep deprivation working while the rest of us slumbers to the after-effects of late-night caffeine, learning to manage night rotations requires a balance of preparation and attention to personal health while caring for others, the residents and adviser said.

Compromised sleep is one of the biggest hurdles residents have to overcome. Sleep loss comes with risks to cardiovascular disease and type 2 diabetes, among other heath conditions, according to Medscape Medical News reports. And night shift workers  who sleep 6 or fewer hours a night have at least one sleep disorder.

Sleep deprivation associated with overnight call schedules also can worsen a resident’s mood and motivation while impairing their judgment, leading to medical errors, according to a new study published in JAMA Open Network. The study proposed shorter consecutive night shifts and naps as ways to offset the results of sleep loss, especially for interns or first-year residents. 

Residency programs recently have been experimenting with shorter call schedules.

 

Catching Zzs

Working the night shift demands a disciplined sleep schedule, said Nat deQuillfeldt, MD, a Denver Health chief resident in the University of Colorado’s internal medicine residency program.

“When I was on night admissions, I was very strict about going to sleep at 8 AM and waking at 3 PM every single day. It can be very tempting to try to stay up and spend time with loved ones, but my husband and I both prioritized my physical well-being for those weeks,” said deQuillfeldt, a PGY-4 resident. “It was especially challenging for me because I had to commute about 50 minutes each way and without such a rigid schedule I would have struggled to be on time.”

deQuillfeldt doesn’t have young children at home, a noisy community, or other distractions to interrupt sleep during the day. But it was still difficult for her to sleep while the sun was out. “I used an eye mask and ear plugs but definitely woke up more often than I would at night.”

Blackout curtains may have helped, she added.

“Without adequate sleep, your clinical thinking is not as sharp. When emergencies happen overnight, you’re often the first person to arrive and need to be able to make rapid, accurate assessments and decisions.”

As a chief resident, she chooses never to sleep during night shifts.

“I personally didn’t want to leave my interns alone or make them feel like they were waking me up or bothering me if they needed help, and I also didn’t want to be groggy in case of a rapid response or code blue.”

But napping on night shift is definitely possible, deQuillfeldt said. Between following up on overnight lab results, answering nurses’ questions, and responding to emergencies, she found downtime on night shift to eat and hydrate. She believes others can catch an hour or 2 of shut eye, even if they work in the intensive care unit, or 3-4 hours on rare quiet nights.

Vater suggests residents transitioning from daytime work to night shift prepare by trying to catch an afternoon nap, staying up later the night before the change, and banking sleep hours in advance.

When he knows he’s starting night shifts, Apurva Popat, MD, said he tries to go to sleep an hour or so later nights before to avoid becoming sleep deprived. The chief resident of internal medicine at Marshfield Clinic Health System in Marshfield, Wisconsin, doesn’t recommend sleeping during the night shift.

“I typically try not to sleep, even if I have time, so I can go home and sleep later in the morning,” said Popat, a PGY-3 resident.

To help him snooze, he uses blackout curtains and a fan to block out noise. His wife, a first-year internal medicine intern, often works a different shift, so she helps set up his sleeping environment and he reciprocates when it’s her turn for night shifts.

Some interns may need to catch a 20- to 30-minute nap on the first night shift, he said.

Popat also seeks out brighter areas of the hospital, such as the emergency department, where there are more people and colleagues to keep him alert.

 

Bypass Vending Machines

Lack of sleep makes it even more difficult to eat healthy on night shift, said Vater, who advises residents about wellness issues at IU and on social media.

“When you are sleep deprived, when you do not get enough sleep, you eat but you don’t feel full,” she said. “It’s hard to eat well on night shift. It’s harder if you go to the break room and there’s candy and junk food.”

Vater said that, as a resident, she brought a lunch bag to the hospital during night shifts. “I never had time to prep food, so I’d bring a whole apple, a whole orange, a whole avocado or nuts. It allowed me to eat more fruits and vegetables than I normally would.”

She advises caution when considering coffee to stay awake, especially after about 9 PM, which could interfere with sleep residents need later when they finish their shifts. Caffeine may help in the moment, but it prevents deep sleep, Vater said. So when residents finally get sleep after their shifts, they may wake up feeling tired, she said.

To avoid sleepiness, Popat brings protein shakes with him to night shifts. They stave off sugar spikes and keep his energy level high, he said. He might have a protein shake and fruit before he leaves home and carry his vegetarian dinner with him to eat in the early morning hours when the hospital is calm.

Eating small and frequent meals also helps ward off sleepiness, deQuillfeldt said.

 

Take the Stairs

Trying to stay healthy on night shifts, Vater also checked on patients by taking the stairs. “I’d set the timer on my phone for 30 minutes and if I got paged at 15, I’d pause the timer and reset it if I had a moment later. I’d get at least 30 minutes in, although not always continuous. I think some activity is better than none.”

Vater said her hospital had a gym, but it wasn’t practical for her because it was further away from where she worked. “Sometimes my coresidents would be more creative, and we would do squats.”

Popat tries to lift weights 2 hours before his night shift, but he also takes short walks between patients’ rooms in the early morning hours when it’s quietest. He also promotes deep breathing to stay alert.

 

Ask for a Ride

Vater urges those coming off night shifts, especially those transitioning for the first time from daytime rotations, not to drive if they’re exhausted. “Get an Uber. ... Make sure you get a ride home.”

The CU residency program covers the cost of a ridesharing service when doctors-in-training are too tired to drive home, deQuillfeldt said. “We really try to encourage people to use this to reduce the risk of car accidents.”

 

Promoting Mental Health

The residency program also links residents with primary care and mental health services. People who really struggle with shift work sleep disorder may qualify for medications to help them stay awake overnight, in addition to sleep hygiene apps and sleep aides.

“Night shifts can put a strain on mental health, especially when you’re only working, eating, and sleeping and not spending any time with family and friends,” deQuillfeldt said. “My husband works late afternoons, so we often would go weeks seeing each other for 15-20 minutes a day.”

“Sleeping when the sun is out often leads to a lack of light exposure which can compound the problem. Seeking mental health support early is really important to avoiding burnout,” she said.

She also recommended planning a fun weekend activity, trip, or celebration with friends or family after night shifts end “so you have something to look forward to…It’s so important to have a light at the end of the tunnel, which will allow you to enjoy the sense of accomplishment even more.”

Cultural competency is one of the most important values in the practice of medicine. Defined as the “ability to collaborate effectively with individuals from different cultures,” this type of competence “improves healthcare experiences and outcomes.” But within the context of cultural familiarity, it’s equally important to “understand that each person is an individual and may or may not adhere to certain cultural beliefs or practices common in his or her culture,” according to the Agency for Healthcare Research and Quality’s (AHRQ’s) Health Literacy Universal Precautions Toolkit.

Sarah Candler, MD, MPH, an internal medicine physician specializing in primary care for older adults in Washington, DC, said that the medical code of ethics consists of several pillars, with patient autonomy as the “first and most primary of those pillars.” She calls the balance of patient autonomy and cultural respect a “complicated tightrope to walk,” but says that these ethical principles can inform medical decisions and the patient-physician relationship.

 

Cultural Familiarity

It’s important to be as familiar as possible with the patient’s culture, Santina Wheat, MD, program director, Northwestern McGaw Family Medicine Residency at Delnor Hospital, Geneva, told this news organization. “For example, we serve many Orthodox Jewish patients. We had a meeting with rabbis from the community to present to us what religious laws might affect our patients. Until recently, I was delivering babies, and there was always a 24-hour emergency rabbi on call if an Orthodox patient wanted the input of a rabbi into her decisions.”

Jay W. Lee, MD, MPH, a member of the board of directors of the American Academy of Family Physicians, also sets out to educate himself about the cultural norms of his patients if they come from populations he’s not familiar with. “For example, this comes up when a new refugee population comes to the United States — most recently, there was a population of Afghan refugees,” Lee told this news organization.

Lee spent “a lot of time trying to learn about their cultural norms,” which prepared him to “ask more targeted questions about the patient’s understanding of the tests we were ordering or treatment options we were bringing forward.”

Lee, also the medical director at Integrated Health Partners of Southern California and associate clinical professor of family medicine at the University of California, Irvine, said it might be best if the physician is “language congruent or culturally similar.” Lee is of Asian descent and also speaks Spanish fluently. “I enjoy cultural exchanges with my patients, and I encourage patients to find a physician who’s the best fit.” But being from the same culture isn’t absolutely necessary for building relationships with the patient. “The key is offering the patient autonomy” while understanding the cultural context.

 

Don’t Assume ... Always Ask

Cultural familiarity doesn’t equate with stereotyping, Wheat emphasized. “Proceeding without assumptions opens the opportunity to ask questions for clarification and understanding and to improve patient care,” said Lee.

Sara Glass, PhD, LCSW, agrees. She’s the clinical director of Soul Wellness NYC, New York City, a psychotherapy practice that specializes in treating trauma. Based on her own experiences, she knows that some physicians and other healthcare professionals confuse cultural sensitivity with cultural stereotyping.

Glass, formerly Hasidic and ultra-Orthodox, shared an example from her own life. During the delivery of her second child, she sustained a vaginal tear. At her 6-week postpartum visit, her ob/gyn said, “Just remind me when you’re in your ninth month next time, and I can sew it up right after you deliver.”

Much of this physician’s practice “consisted of Hasidic women who looked just like me, wearing the same garb — head coverings such as wigs and scarves and long skirts. Most women in that community have multiple pregnancies,” Glass told this news organization. “My sister has 10 children, and that’s not unusual. The doctor simply assumed I’d be going on to have more babies without asking if that’s what I wanted.”

Glass says she was also never given information by her physician about the range of available contraceptive options. The rabbis of the Hasidic sect to which Glass belonged allowed women to practice contraception for 6 months following childbirth, or for longer, in the setting of certain medical conditions, but only certain types of birth control were religiously permissible. Other options were not mentioned to her by her physician, and she didn’t know that they existed.

Making no assumptions applies not only to patients from other cultures but also to all patients — including members of “mainstream American culture.”

Candler recalls a young patient with a new baby, who shared “how exhausted she was and how much time, energy, and work it took to care for children,” Candler recounted. “To me, it sounded as though she didn’t want another child, and I was about to offer contraception when it occurred to me to first ask if she wanted to have more children.” Candler was surprised when the patient said that, although she wasn’t actively looking to become pregnant again, she didn’t want to take preventive measures. “I’m so glad I asked, rather than simply assuming.”

 

Culture Is Mutable

Important questions to ask patients include whether there are aspects of their culture or religion that might affect their care — which can include medications they may feel uncomfortable using — and what family members they want to have involved in clinical discussions and decisions, said Wheat.

Lee described treating a refugee from Afghanistan who was in her sixth month of pregnancy. “I quickly needed to learn about what her expectations were for her care and my presence as a male on her care team,” he recounted. Lee arranged for the patient to receive prenatal care from a different clinician and arranged for follow-up for her husband and children. “Everyone had good results.”

Candler noted that some patients choose their physician specifically because that practitioner is conversant with their culture and respectful of its mores — especially when physicians share the same culture as the patient. But that level of familiarity can make it easy to forget to ask questions about the experience of the individual patient within that culture.

Moreover, Glass suggested, some physicians who treat patients from a particular culture or religious group may be concerned about offending them or antagonizing religious leaders if they discuss medical options that aren’t accepted or practiced in that community or culture, such as vasectomy for male contraception. “But that deprives patients of knowing what choices are available and making truly informed decisions.”

This is especially important because “culture is mutable,” said Candler, and religious or cultural practices can “look one way on paper but be implemented, adopted, or executed in a completely different way by every human being who lives in that culture.” The best cultural competency “comes from continuing to build relationships with our patients. But even in a single visit, a single hospitalization, we should get to know patients as human beings, not just members of a given culture.”

There are cultures in which families want to be the liaison between the patient and the physician and to make decisions on the patient’s behalf. “I always ask patients what role they want their family members to play even if the cultural expectation is that the family will be heavily involved,” Candler said.

Sometimes, this can be awkward, and families might become upset. Candler described an elderly, frail patient who was diagnosed with end-stage cancer. She had always relied heavily on family to care for her. Concerned about overburdening them, she didn’t want them to know her diagnosis. The patient was mentally competent to make that decision.

“Usually, I would have had the family at the bedside so I could be sure everyone was appropriately informed and prepared for what lay ahead, but in this case, I couldn’t do so,” Candler said. “I had to inform her entire care team not to discuss the cancer diagnosis with any family members because this was the patient’s express wish. And when the family asked me if the diagnosis was cancer, I had to respond, ‘I’m so sorry, but your loved one doesn’t want us to discuss details of her diagnosis.’”

Other patients don’t want to know their own diagnosis and specifically ask Candler to inform a family member. “I’ve had patients request that I tell their children. They want their children to make decisions on their behalf.”

The main thing, Candler emphasized, is to “ask the patient, make sure the patient is competent to make that decision, thoroughly document the patient’s decision in the chart, and respect whatever that decision is.”

 

You Can Revisit the Questions

Having a longitudinal relationship means that the physician can revisit the same questions at different junctures because people’s perspectives sometimes change over time. “Discussing what a patient wants isn’t necessarily a one-time occurrence,” Wheat said. For example, “I’ve had situations where a patient has been a member of Jehovah’s Witnesses and won’t accept blood products — like transfusions — in treatment. I tell these patients that if an emergent situation arises, I would like to have the conversation again.”

Of course, sometimes patients are seen in the emergency department or in other situations where the physician has no prior relationship with them. “I always go into a room, especially with new patients, aiming to build rapport, communicate with a high level of respect, introduce myself, explain my approach, and understand the patient’s wishes,” Lee said. “As scenarios play out, I ask in multiple ways for the patient to confirm those wishes.”

He acknowledges that this can be time-consuming, “but it helps ensure the care that patient receives is complete, thorough, comprehensive, and respectful of the patient’s values and wishes.”

Candler disclosed paid part-time clinical work at CuraCapitol Primary Care Services, volunteer advocacy (reimbursed for travel) for the American College of Physicians, volunteer advocacy (reimbursed for travel) for the American Medical Association while serving on their Task Force to Preserve the Patient-Physician Relationship, and serving as a partner representative (reimbursed for time) for the AHRQ’s Person-Centered Care Planning Partnership, representing the American College of Physicians. Lee, Wheat, and Glass disclosed no relevant financial relationships.

Cultural competency is one of the most important values in the practice of medicine. Defined as the “ability to collaborate effectively with individuals from different cultures,” this type of competence “improves healthcare experiences and outcomes.” But within the context of cultural familiarity, it’s equally important to “understand that each person is an individual and may or may not adhere to certain cultural beliefs or practices common in his or her culture,” according to the Agency for Healthcare Research and Quality’s (AHRQ’s) Health Literacy Universal Precautions Toolkit.

Sarah Candler, MD, MPH, an internal medicine physician specializing in primary care for older adults in Washington, DC, said that the medical code of ethics consists of several pillars, with patient autonomy as the “first and most primary of those pillars.” She calls the balance of patient autonomy and cultural respect a “complicated tightrope to walk,” but says that these ethical principles can inform medical decisions and the patient-physician relationship.

Interventions during holidays and school vacations can help prevent children and adults gaining weight, according to a recent systematic review and meta-analysis published in Obesity Reviews.

Evidence suggests that certain times of the year, such as the Christmas holidays and summer vacations, are associated with weight gain. In adults, up to 50% of the total annual weight gain occurs during December.

In 2023, the United Nations Children’s Fund reported that more than four million children younger than 5 years and nearly 50 million children and adolescents aged 5-19 years in Latin America and the Caribbean were affected by overweight. Among adults, more than 50% of individuals in every country in the region live with obesity.

These alarming figures call for urgent action from governments, healthcare professionals, and multidisciplinary teams to implement prevention strategies and promote further research.

 

Study Significance

Michelle Maree Haby de Sosa, PhD, an epidemiologist and researcher at the Department of Chemical-Biological and Nutritional Sciences at the University of Sonora, Hermosillo, Mexico, led the study. She explained that the research team first conducted a narrative review on weight gain during the festive season. “We found that the 6 weeks between December and mid-January represent a critical period when people gain half the weight they put on all year. This highlights the importance of addressing obesity and overweight by promoting lifestyle changes and prevention strategies to tackle this public health issue.”

The researchers then conducted a systematic review of global interventions not only to publish findings but also to educate healthcare professionals and stakeholders. They searched databases such as Medline, EMBASE, PsycINFO, SciELO, LILACS, and Cochrane, focusing on randomized controlled trials. These were supplemented with gray literature and references from relevant articles, as well as additional data requested from study authors.

 

Key Findings

The review included studies from the United States (10), the United Kingdom (one), and Chile (one). Of these, two had a low risk for bias, two moderate, seven high, and one critical.

Most interventions targeted school-aged children or adults. According to Haby de Sosa, achieving consistent results in adolescents was challenging due to the difficulty of changing behaviors in this age group. In contrast, interventions for school-aged children were implemented primarily during day camp visits, where participants were divided into control and intervention groups.

The interventions included nutrition classes, physical activity, and the provision of healthy meals, which resulted in less weight gain compared with control groups.

In children, the meta-analysis of four of seven studies conducted during summer vacations (six interventions) found a small but significant reduction in body mass index z-scores in the intervention group (−0.06; 95% CI, −0.10 to −0.01; P = .01; I² = 0%; very low-certainty evidence).

Among adults, interventions also generally proved effective, despite variations in implementation. A meta-analysis of five studies involving 462 participants (234 intervention, 228 control) showed a slight reduction in body weight (−0.99 kg; 95% CI, −2.15 to 0.18; P = 0.10; I² = 89%).

Three key intervention areas were identified: Nutrition, physical activity, and psychological support including behavioral and cognitive elements. Strict diets were generally not a priority; instead, participants were advised to reduce consumption of high-calorie food and sugary beverages while increasing their intake of vegetables.

 

Promising Interventions

The study highlighted specific interventions for children and adults:

• Children: 6- to 8-week summer camps with daily physical activities such as sports and crafts, complemented by free, nutritious meals.
• Adults: Daily weight monitoring paired with nutrition counseling based on social cognitive theory. Interventions lasted 4 to 8 weeks, spanning mid-November to early January.

Expert Recommendations

Carlos Cristi-Montero, PhD, a researcher at Pontificia Universidad Católica de Valparaíso, Chile, and an author of a Chilean intervention study, shared insights with this news organization.

He emphasized the importance of portion control for children. “During the holidays, families prepare calorie-rich dishes but often fail to consider portion sizes,” he noted. “Children are treated like adults, which contributes to excessive caloric intake. Our interventions focused on teaching people about portion control, the caloric content of their meals, and the risks of overweight and obesity, as well as the benefits of healthy eating.”

He also stressed the importance of evaluating not just weight but body composition, using tools like dual-energy x-ray absorptiometry to measure fat and muscle mass.

Cristi-Montero also highlighted the importance of physical activity: “We emphasize the value of exercise and staying active as key strategies to prevent weight gain.”

 

Steps for Successful Interventions

Educating teachers and parents to reinforce healthy behaviors is also vital, according to Cristi-Montero, as obesity impacts not only metabolic health but also academic performance and mental health.

Both Haby de Sosa and Cristi-Montero agreed that primary care professionals have an important role in driving effective interventions, alongside participation in research to refine prevention strategies. Multidisciplinary teams — including nutritionists, psychologists, exercise specialists, teachers, and parents — can play a part in preventing weight gain during holidays.

 

Future Directions

The University of Sonora research team is currently conducting a controlled trial in Hermosillo, Mexico, involving adult participants divided into intervention and control groups. Preliminary results, already published online, highlight the effectiveness of strategies such as nutrition education, physical activity, regular weight goals, and psychological support in promoting habit changes.

“Interventions to prevent weight gain during the holidays and summer vacations are necessary,” the authors concluded, emphasizing the need for further research to evaluate their effectiveness in the region.

Haby de Sosa or Cristi-Montero declared no relevant financial conflicts of interest.

These were supplemented with gray literature and references from relevant articles, as well as additional data requested from study authors.

 

Key Findings

The review included studies from the United States (10), the United Kingdom (one), and Chile (one). Of these, two had a low risk for bias, two moderate, seven high, and one critical.

Most interventions targeted school-aged children or adults. According to Haby de Sosa, achieving consistent results in adolescents was challenging due to the difficulty of changing behaviors in this age group. In contrast, interventions for school-aged children were implemented primarily during day camp visits, where participants were divided into control and intervention groups.

The interventions included nutrition classes, physical activity, and the provision of healthy meals, which resulted in less weight gain compared with control groups.

In children, the meta-analysis of four of seven studies conducted during summer vacations (six interventions) found a small but significant reduction in body mass index z-scores in the intervention group (−0.06; 95% CI, −0.10 to −0.01; P = .01; I² = 0%; very low-certainty evidence).

Among adults, interventions also generally proved effective, despite variations in implementation. A meta-analysis of five studies involving 462 participants (234 intervention, 228 control) showed a slight reduction in body weight (−0.99 kg; 95% CI, −2.15 to 0.18; P = 0.10; I² = 89%).

Three key intervention areas were identified: Nutrition, physical activity, and psychological support including behavioral and cognitive elements. Strict diets were generally not a priority; instead, participants were advised to reduce consumption of high-calorie food and sugary beverages while increasing their intake of vegetables.

 

Promising Interventions

The study highlighted specific interventions for children and adults:

• Children: 6- to 8-week summer camps with daily physical activities such as sports and crafts, complemented by free, nutritious meals.
• Adults: Daily weight monitoring paired with nutrition counseling based on social cognitive theory. Interventions lasted 4 to 8 weeks, spanning mid-November to early January.

Expert Recommendations

Carlos Cristi-Montero, PhD, a researcher at Pontificia Universidad Católica de Valparaíso, Chile, and an author of a Chilean intervention study, shared insights with this news organization.

He emphasized the importance of portion control for children. “During the holidays, families prepare calorie-rich dishes but often fail to consider portion sizes,” he noted. “Children are treated like adults, which contributes to excessive caloric intake. Our interventions focused on teaching people about portion control, the caloric content of their meals, and the risks of overweight and obesity, as well as the benefits of healthy eating.”

He also stressed the importance of evaluating not just weight but body composition, using tools like dual-energy x-ray absorptiometry to measure fat and muscle mass.

Cristi-Montero also highlighted the importance of physical activity: “We emphasize the value of exercise and staying active as key strategies to prevent weight gain.”

 

Steps for Successful Interventions

Educating teachers and parents to reinforce healthy behaviors is also vital, according to Cristi-Montero, as obesity impacts not only metabolic health but also academic performance and mental health.

Both Haby de Sosa and Cristi-Montero agreed that primary care professionals have an important role in driving effective interventions, alongside participation in research to refine prevention strategies. Multidisciplinary teams — including nutritionists, psychologists, exercise specialists, teachers, and parents — can play a part in preventing weight gain during holidays.

 

Future Directions

The University of Sonora research team is currently conducting a controlled trial in Hermosillo, Mexico, involving adult participants divided into intervention and control groups. Preliminary results, already published online, highlight the effectiveness of strategies such as nutrition education, physical activity, regular weight goals, and psychological support in promoting habit changes.

“Interventions to prevent weight gain during the holidays and summer vacations are necessary,” the authors concluded, emphasizing the need for further research to evaluate their effectiveness in the region.

Haby de Sosa or Cristi-Montero declared no relevant financial conflicts of interest.

Interventions during holidays and school vacations can help prevent children and adults gaining weight, according to a recent systematic review and meta-analysis published in Obesity Reviews.

Evidence suggests that certain times of the year, such as the Christmas holidays and summer vacations, are associated with weight gain. In adults, up to 50% of the total annual weight gain occurs during December.

In 2023, the United Nations Children’s Fund reported that more than four million children younger than 5 years and nearly 50 million children and adolescents aged 5-19 years in Latin America and the Caribbean were affected by overweight. Among adults, more than 50% of individuals in every country in the region live with obesity.

These alarming figures call for urgent action from governments, healthcare professionals, and multidisciplinary teams to implement prevention strategies and promote further research.

 

Study Significance

Michelle Maree Haby de Sosa, PhD, an epidemiologist and researcher at the Department of Chemical-Biological and Nutritional Sciences at the University of Sonora, Hermosillo, Mexico, led the study. She explained that the research team first conducted a narrative review on weight gain during the festive season. “We found that the 6 weeks between December and mid-January represent a critical period when people gain half the weight they put on all year. This highlights the importance of addressing obesity and overweight by promoting lifestyle changes and prevention strategies to tackle this public health issue.”

The researchers then conducted a systematic review of global interventions not only to publish findings but also to educate healthcare professionals and stakeholders. They searched databases such as Medline, EMBASE, PsycINFO, SciELO, LILACS, and Cochrane, focusing on randomized controlled trials. These were supplemented with gray literature and references from relevant articles, as well as additional data requested from study authors.
