CrossFit, the widely known fitness platform and brand with thousands of affiliated gyms, is moving into primary care with the launch of its newest service, CrossFit Precision Care.

Developed by family medicine physician Julie Foucher, MD, and other CrossFit-trained doctors, the new service aims to help CrossFit members build plans to protect and improve their health, according to a statement by the company.

CrossFit Precision Care plans to meet this goal through utilizing doctors who understand the CrossFit philosophy, individualized care, data-driven recommendations, proactive lifestyle changes, and continual health optimization. Informing these plans and changes are CrossFit Precision Care’s analysis through a few different methods.

CrossFit’s partner in the endeavor, Wild Health, will provide genomic testing to determine a patient’s genetic predispositions to help optimize the health plans. Blood testing reveals many things that may affect a person’s health, such as hormone status, lipid levels, thyroid function, and cardiovascular risks. An overall lifestyle review includes exercise routines, eating habits, social life, and other patterns or behaviors.
 

Connecting with doctors who understand CrossFit

Dr. Foucher is no stranger to CrossFit. She has competed in the CrossFit Games four times and discusses the sport regularly on Twitter and Instagram. Now, she works directly with CrossFit to help it provide users with individualized data-driven plans.

“I met Eric Roza last July,” Dr. Foucher says of CrossFit’s CEO. “We talked and saw a lot of potential for CrossFit and health care providers to work together, so we started brainstorming.”

When Dr. Foucher and Mr. Roza got to know Wild Health, specifically, two of its physician cofounders, it was a natural fit, she said. Dr. Foucher says that many who train in CrossFit or go to CrossFit-affiliated gyms feel a disconnect with their family doctors: “[CrossFit is] a pretty polarizing topic, but there are also a lot of doctors who know that people are having health improvements with these programs,” she said.

Through use of Wild Health’s precision services and algorithms, CrossFit Precision Care plans to connect its users with CrossFit-trained health care practitioners. This personalized approach allows health care practitioners to build closer relationships with users of the program, who may feel more comfortable working with doctors who understand their lifestyle. Wild Health’s precision medicine approach, with trackable data such as biomarker status and risk scores, gives doctors a more complete picture of a patient’s needs and history, according to a statement on the partnership.
 

A better use of data

“To me,” Dr. Foucher says of family medicine, “that was the best option coming out of residency. It was consistent with my morals.” She says much of the current health care system is algorithm based. If a patient is experiencing certain symptoms, treatment is recommended on the basis of whatever yields the best results from the data – but this doesn’t always factor in a patient’s full history and genetics. It can be difficult for doctors to build trusting and personal relationships with patients. “In our current system, there’s not a lot of time or great tools to do that,” she says.

With the approach Wild Health and CrossFit Precision Care both use, however, Dr. Foucher says she sees a huge opportunity for optimizing patient and health care practitioner relationships.

“I see huge potential here, and I really think that this should be the standard for primary care going forwards,” Dr. Foucher explains. “The nice thing about [this approach] is that it has a really quick learning curve and is relatively easy to implement with patients. Before Wild Health optimized it, the tech and data would take about 10 hours per patient to put together. But now, we can incorporate things that work with wearable tech and track results over time and allow the patient and doctor to use this platform to create relationships. And this is something that can scale to many more patients.”

According to its website, CrossFit Precision Care is currently launching an invite-only beta test version of the program in eight states ahead of an expected national release.

The Food and Drug Administration has approved a modification to the isotretinoin risk-mitigation program to make it more inclusive for transgender patients.

Beginning on Dec. 13, 2021, patients prescribed isotretinoin for acne will be assigned to one of two risk categories – those who can get pregnant and those who cannot for the iPLEDGE Risk Evaluation and Mitigation Strategy (REMS). Previously, there were three risk categories: females of reproductive potential, females not of reproductive potential, and males.

In recent years, dermatologists and others have advocated for the change, hoping to make the process more inclusive and less intrusive for their transgender patients.

Isotretinoin (Accutane, Absorica, Amnesteem, Claravis, others) has a high risk of severe birth defects, and has been linked with other health issues, making it crucial for those with the ability to become pregnant to take contraceptive precautions while on the medication. Under the iPLEDGE program, physicians, patients, and pharmacies prescribing, using, or dispensing the drug must all be registered, with requirements that include the use of two forms of an effective contraceptive and regular pregnancy testing for patients who can become pregnant.

The FDA had given notification in June 2018 that the REMS modification and labeling change would be required, replacing the gender-specific language with gender-neutral language, according to an FDA spokesperson. The change was based on feedback that the gender-specific language can be a barrier to access for some patients. The FDA approved the modification on Oct. 8.
 

Expert reactions

“This is an exciting and welcome change from the FDA on iPLEDGE that many dermatologists, myself included, have advocated for quite a few years,” Howa Yeung, MD, MSc, assistant professor of dermatology at Emory University, Atlanta, said in an interview.

In a report on the dermatologic care for lesbian, gay, bisexual, and transgender persons published in the Journal of the American Academy of Dermatology, Dr. Yeung and his colleagues noted that more than 10 million lesbian, gay, bisexual and transgender people live in the United States and that improving their health is a public health priority.

“For cisgender patients, nothing has changed – patients will continue to receive appropriate educational material related to isotretinoin based on their pregnancy potential,” Dr. Yeung said. “For transgender and gender diverse patients, this is a huge step forward.”

Under the previous system, doctors were asked to register patients using gender binary categories, “which were confusing when they did not reflect reality” for these patients, Dr. Yeung said. The new system, Dr. Yeung added, “will make my job easier. I no longer have to struggle between respecting the patient’s gender identity and providing medically necessary care for patients with severe acne.”

“The new terminology is not just respectful, it also is simpler and makes more sense,” agreed Joshua D. Safer, MD, executive director of the Center for Transgender Medicine and Surgery at Mount Sinai Health System and professor of medicine at the Icahn School of Medicine at Mount Sinai, New York. “As it stood, a transgender man with his uterus and ovaries in place might be missed in the pregnancy surveillance system because he could simply be labeled a man and not followed further. At the same time, both transgender women and cisgender women who were at no risk of pregnancy could be subject to more medical scrutiny that might have been consider intrusive.”

The change “validates the important point that pregnancy potential is not exclusively defined by sociocultural constructs of gender and allow dermatologists to focus purely on what matters when prescribing isotretinoin – whether an individual is able to become pregnant or not, regardless of their gender identity,” Klint Peebles, MD, a dermatologist at Kaiser Permanente in Washington, D.C., and suburban Maryland, who has also advocated for the change, said in an interview.

 

FDA elaborates

The modification includes important changes for doctors, pharmacists, and patients alike, according to the FDA.

Health care providers must assign and confirm their currently enrolled patient’s risk category when they first log in to the IPLEDGE REMS website on or after Dec. 13, the effective date. They should be sure any patient whose prescription RMA (iPLEDGE authorization) expires on Dec. 11-12 is told to obtain their prescription before midnight, Eastern time, Dec. 10.

Pharmacists will be affected, too, since the iPLEDGE REMS changed to a new platform vendor and the current “switch” pharmacy management system will be removed as a method to verify authorization to dispense isotretinoin. With these changes, as of Dec. 13, pharmacists can’t use the switch system to obtain a predispense authorization, or RMA (risk management authorization). They will need to obtain an RMA online by accessing the iPLEDGE REMS website or via telephone to the PLEDGE REMS center, 866-495-0654, before dispensing the prescription.

Patients, beginning Dec. 13, will have the option of presenting a unique QR code at the pharmacy on their smartphone rather than providing the iPLEDGE identification number. The code can be accessed by logging into their account on the iPLEDGE REMS website.

Patients with an isotretinoin prescription RMA that expires Dec. 11-12, must obtain the prescription before 11:59 p.m. Eastern time on Dec. 10. If the RMA expires before the prescription is picked up, the patient must begin the authorization process all over again.

Dr. Safer, Dr. Yeung, and Dr. Peebles have no relevant disclosures.

With all the lockdowns and social distancing of the pandemic, millions of people have had a lot of time to themselves. Many may have filled that time with baking, long walks, or video games, but minds wandering during these periods was inevitable. Coincident with these experiences were increases in depression and anxiety, which could be linked to the same brain network that is thought to support a meandering mind, called the default mode network.

Scientists interested in this network wanted to understand how wandering thoughts can lead some people to a state of brooding in which the same negative thoughts resurface repeatedly. To gain some insight into these patterns, they recorded more than 2,000 thoughts spoken aloud by 78 study participants who did nothing but let their minds wander for 10 minutes.

Senior researcher Jessica Andrews-Hanna, PhD, assistant professor of psychology, University of Arizona, Tucson, and colleagues hoped that analyzing these stream-of-consciousness thoughts could yield insights into how people become stuck in negative mental spirals.

They found that most participants thought about the present or future in words that were neither particularly negative nor positive. Almost three-quarters of the thoughts were focused inward on the person or were imaginative.
 

Negativity breeds negativity

But the investigators found an interesting pattern with regard to negative thoughts. The more negative someone’s thoughts became, the more likely that their next idea would be related to their previous one. In other words, negative thoughts created a chain reaction of more negative thoughts.

Positive thoughts, in contrast, tended to be followed by completely unrelated ruminations, indicating true mental meandering. The pattern suggested that negativity tends to narrow the range of thoughts, whereas positivity tends to expand it during periods in which the mind wanders.

The researchers also found, unsurprisingly, that negative thoughts that were focused on the self and on the past were more likely to result in brooding and that positive thoughts were less likely to arise.

Most study participants were young and educated and may have only said things that they were comfortable allowing the researchers to hear. And because the authors didn’t ask participants about their moods, the investigators could not associate specific patterns of thought with any mental health conditions.

Although the findings, published in Scientific Reports, do not on their own point to solutions for depression or anxiety, they may offer a starting point for future research into how negative trains of thoughts begin – and perhaps how to derail them.

For many children in the process of outgrowing egg allergy, the step-wise reintroduction of foods that contain eggs can be achieved at home using a nine-rung laddered approach, according to updated guidelines from the British Society for Allergy and Clinical Immunology (BSACI).

Attempts to reintroduce egg into the child’s diet can start at the age of 12 months or 6 months from the last reaction, as long as past reactions have been mild to moderate and the child does not have asthma, according to guidelines from the BSACI, which represents allergists, pediatricians, and other health care practitioners.

According to the guidelines, the reintroduction needs to be guided by a specialist allergy service for children who have had severe reactions to egg or who have asthma.

Susan C. Leech, MB BChir, DCH, first author of the guidelines and a consultant in pediatric allergy with the Department of Child Health at Kings College Hospital, London, told this news organization that home reintroduction should begin slowly with small amounts of baked egg, starting with a pea-sized piece of cake, and should proceed gradually.

“Parents can be reassured that it’s a relatively safe thing to do as long as it’s done with caution,” said Dr. Leech.

The expanded guidelines include a new nine-step reintroduction ladder. It builds on a three-stage classification of egg-containing foods that was first introduced in BSACI guidelines in 2010.

On the bottom four rungs, children work their way through small but increasing amounts of fairy cakes (cupcakes), biscuits (cookies), and other foods containing baked eggs.

The next three rungs involve hard-boiled eggs, quiche, and other well-cooked egg products.

At the eighth rung, children can have small mouthfuls of runny scrambled eggs, mayonnaise, and other less-cooked or raw egg-containing products. At the top rung, children can have increasing amounts of those products as well as licks of cake batter.

The guidelines were published online September 29 in Clinical and Experimental Allergy along with a supplement that includes a series of examples showing how the guidelines apply to specific patient cases.

“These are examples only,” the guideline authors caution in the appendix. “Clinical judgment of severity is important as risk assessment is not always easy.”

Anna Nowak-Wegrzyn, MD, PhD, a professor of pediatrics at NYU Grossman School of Medicine and chief of pediatric allergy and immunology for Hassenfeld Children’s Hospital at NYU Langone, who was not involved in the BSACI guidelines, described the egg ladder as a “proactive” strategy that deserves further study and consideration.

“I think that this may be a valid approach,” said Dr. Nowak-Wegrzyn in an interview. “Eggs have good nutritional value, and they are present in a lot of foods, so avoidance creates logistical challenges.”

Using the egg ladder for home-based reintroduction may be especially suited in resource-poor areas where access to an allergist may be difficult, she said. It may also be suited for families that can’t visit the office because of pandemic-related restrictions.

“If the child had a severe reaction or if they have asthma, then it’s a no-go,” she added, “but if you have a patient who has a really mild reaction and you think that overall the risk of a significant reaction or bad symptoms is low, then it may be worth doing.”

Dr. Leech and Dr. Nowak-Wegrzyn have disclosed no relevant financial relationships.

In frail elderly adults with COVID-19 infections, treatment with omega-3 fatty acids may improve lipid responses and decrease levels of proinflammatory lipid mediators, results of a small randomized controlled trial suggest.

Results of the study, which included 22 patients with multiple comorbidities, were presented at the European Geriatric Medicine Society annual congress, a hybrid live and online meeting.

The patients, who had a median age of 81 years, were randomized to receive an intravenous infusion of an omega-3 polyunsaturated fatty acid (PUFA) emulsion containing 10 g of fish oil per 100 mL or a saline placebo.

Those who received the intravenous infusion had significant decreases from baseline to end of treatment in the neutrophil-to-lymphocyte ratio (NLR), indicating marked reductions in systemic inflammation.

In contrast, patients randomized to a saline placebo had no significant improvements in NLR, Magnus Bäck, MD, PhD, from the Karolinska Institute in Stockholm reported at the meeting.

“Our lipidomic analysis also showed that omega-3 treatment skewed the lipid response, with reduced levels of proinflammatory lipid mediators, and increased levels of proresolving mediators,” according to a late-breaking abstract, which Dr. Bäck presented during the session.

Omega-3 treatment was not significantly associated with reduction in either C-reactive protein (CRP) or the proinflammatory cytokine interleukin-6, however.
 

‘Eicosanoid storm’

In a review article published in January 2021 in the open-access journal Frontiers in Physiology, Dr. Bäck and colleagues outlined the rationale for their randomized trial.

“Excessive inflammation has been reported in severe cases with respiratory failure and cardiovascular complications,” they wrote. “In addition to the release of cytokines, referred to as cytokine release syndrome or ‘cytokine storm,’ increased proinflammatory lipid mediators derived from the omega-6 polyunsaturated fatty acid (PUFA) arachidonic acid may cause an ‘eicosanoid storm,’ which contributes to the uncontrolled systemic inflammation.”

Omega-3 PUFA contains proresolving mediators that can limit inflammatory reactions, suggesting the possibility of an inflammation-resolving benefit in patients with COVID-19 without concerns about immunosuppression, the authors hypothesized.
 

Trial details

In the trial, COVID-Omega-F, they enrolled patients with a COVID-19 diagnosis requiring hospitalization. Patients with an allergy to fish oil or who had contraindications to intravenous PUFA administration (for example, risk for bleeding, shock, or emboli) were excluded.

Ten patients were randomly assigned to receive infusions of the omega-3 PUFA and 12 were assigned to receive infusions of the placebo, once daily for 5 days. The primary outcome measure was change in inflammatory biomarkers, including white blood cell counts, CRP, cytokines, and lipid mediators.

Baseline demographic and clinical characteristics were similar between the two study arms, with a median of about 7 days since the onset of symptoms, and 3.5 days since a diagnosis of COVID-19.

All patients had low lymphocyte responses reflected by a high NLR, a prognostic measure for worse outcomes in patients with COVID-19 infections, Dr. Bäck said.

Inflammation was moderate, with a CRP of 65 mg/L in the placebo group and 62 mg/L in the omega-3 group.

Seven patients in each study arm received concomitant corticoid treatment. Two patients in each arm died in hospital, but there were no serious treatment-related adverse events.
 

Inflammatory markers improve

As noted before, there was a significant decline in NLR from baseline among patients randomized to omega-3 (P = .02) but no corresponding decrease in patients assigned to placebo infusions.

“The significant decrease was largely driven by an increase in the lymphocyte count in the omega-3 treated group (P = .004), whereas lymphocytes did not significantly change,” Dr. Bäck said.

As expected, patients in the omega-3 group had pronounced increases in omega-3 fatty acids, including eicosapentaenoic acid and docosahexaenoic acid.

The metabolism of fatty acids also differed markedly between the groups, with a significant decrease in the omega-3 group but not the placebo group in proinflammatory mediators, and an increase in precursors to proresolving mediators, Dr. Bäck noted.
 

AFib concerns

In a question-and-answer part of the session, a physician who identified herself as “Senya from Russia” questioned the safety of omega-3 treatment in this population, “because recently there was a meta-analysis which showed that omega-3 fatty acids will increase the risk of atrial fibrillation in older adults especially.”

The systematic review and meta-analysis she referred to, published in Circulation and reported on by this news organization, showed that, among 81,210 patients with a mean age of 65 enrolled in seven randomized controlled trials, omega-3 fatty acid supplementation was associated with a 25% increase in risk for atrial fibrillation. This risk appeared to be higher in trials testing doses greater than 1 g/day, according to the paper.

“This was not monitored in this study,” Dr. Bäck replied. “It is true that the meta-analysis showed an increased incidence of atrial fibrillation, so it would be something to monitor in case this trial would be expanded to a larger population.”

The study was supported by the Karolinska Institute. Dr. Bäck disclosed no relevant financial relationships.

Wide-area transepithelial sampling with 3D (WATS-3D) analysis increased detection of dysplasia when used as an adjunct to the Seattle forceps biopsy protocol in patients with Barrett’s esophagus, according to a recent meta-analysis. While the findings demonstrate potential for increased dysplasia detection, the analysis failed to identify the clinical significance of this detection.

Despite its ability to evaluate Barrett’s esophagus segments and examine targeted biopsies of mucosal abnormalities, the Seattle protocol is primarily limited by lack of adherence and increased risk of sampling error. “Moreover, the rates of ‘missed’ dysplasia and EAC [esophageal adenocarcinoma] remain high, with up to a quarter of all EAC being ‘missed,’ ” wrote study authors Don Codipilly, MD, of the Mayo Clinic, and colleagues. The report is in Gastrointestinal Endoscopy.

There are challenges associated with the Seattle protocol, specifically poor protocol adherence and missed identification of subtle abnormalities potentially harboring dysplasia. In contrast, the novel WATS-3D may overcome issues related to sampling error due to its ability to obtain higher proportions of Barrett’s esophagus mucosa through the use of a brush-only technique. According to the researchers, previous studies suggest WATS-3D may increase dysplasia yield by approximately 40% compared with conventional surveillance methods.

To gauge the incremental yield of WATS-3D for dysplasia detection compared with the Seattle forceps biopsy protocol, Dr. Codipilly and colleagues performed a systematic review and meta-analysis of seven studies using the two techniques from 2000 to 2020. The researchers defined “incremental yield” of detected dysplasia as a composite of indefinite for dysplasia, low-grade dysplasia, high-grade dysplasia (HGD), and esophageal adenocarcinoma (EAC). They also compared the two surveillance techniques in terms of incremental yields of HGD/EAC, as well as the rate of reconfirmation of WATS-3D dysplasia on subsequent forceps biopsies.

The seven studies in the final analysis included a pooled cohort of 3,206 patients. According to the meta-analysis, forceps biopsies diagnosed dysplasia in 15.9% (95% confidence interval, 5.4-30.5) of all cases, while the incremental yield of WATS-3D was 7.2% (95% CI, 3.9-11.5). In the pooled analysis of six studies that reported the secondary outcomes, forceps biopsies diagnosed HGD/EAC in 2.3% (95% CI, 0.6-5.1) of patients, while the incremental yield with WATS-3D was 2.1% (95% CI, 0.4-5.3). The researchers point out that WATS-3D was negative in 62.5% of cases where forceps biopsies detected dysplasia. Reports from two of the studies reconfirmed WATS-3D dysplasia with forceps biopsies histology in 20 patients.

“Based on these findings, it cannot be recommended to replace the Seattle Protocol but instead to use both techniques in conjunction to detect dysplasia most effectively,” Omar Awais, DO, assistant professor of surgery in the Department of Cardiothoracic Surgery at the University of Pittsburgh School of Medicine, said in an email to this news organization.

Dr. Awais, who was not involved in the meta-analysis, suggests further prospective, randomized studies are needed to confirm the results. “Additionally, we will also need studies to show cost-effectiveness for using WATS-3D in addition to Seattle protocol, as these may help verify WATS-3D dysplasia by standard endoscopic protocol and show we are not missing dysplasia using the technique,” he said.

Felice H. Schnoll-Sussman, MD, professor of clinical medicine and director of the Jay Monahan Center for Gastrointestinal Health at New York–Presbyterian Hospital/Weill Medical College, added that the meta-analysis “adds to our understanding” of the place of WATS as an adjunct approach in dysplasia detection. “In spite of the rigid selection of studies, this analysis also leaves us with questions about the overall utility of WATS given the lack of follow-up cases where dysplasia was only identified on the WATS brush as well as the overall cost-effectiveness of this approach,” she said.

Dr. Schnoll-Sussman, who was not involved in the study conducted by Dr. Codipilly and colleagues, told this news organization that one of the issues with the WATS brush is obtaining adequate sampling, which may impede adherence. “Attention has to be paid to sampling all quadrants with the brush, which at times may be challenging, especially in esophagi that are tortuous, angulated, or dilated,” she explained. “Like with any endoscopic technique, care must be taken to obtain high-yield sampling.”

Dr. Schnoll-Sussman noted that the subtle, small areas of denuded mucosa left where the brush has made appropriate contact with the mucosa should be appreciated during sampling. “Taking one’s time to sample the esophageal lining – a major reason for missed lesions in the Seattle protocol – can also become an issue with WATS,” she added.

The study researchers reported conflicts of interest with several pharmaceutical companies. No funding was reported for the study. Dr. Awais and Dr. Schnoll-Sussman had no conflicts to disclose.

Dr. Schnoll-Sussman noted that the subtle, small areas of denuded mucosa left where the brush has made appropriate contact with the mucosa should be appreciated during sampling. “Taking one’s time to sample the esophageal lining – a major reason for missed lesions in the Seattle protocol – can also become an issue with WATS,” she added.

The study researchers reported conflicts of interest with several pharmaceutical companies. No funding was reported for the study. Dr. Awais and Dr. Schnoll-Sussman had no conflicts to disclose.

Wide-area transepithelial sampling with 3D (WATS-3D) analysis increased detection of dysplasia when used as an adjunct to the Seattle forceps biopsy protocol in patients with Barrett’s esophagus, according to a recent meta-analysis. While the findings demonstrate potential for increased dysplasia detection, the analysis failed to identify the clinical significance of this detection.

Despite its ability to evaluate Barrett’s esophagus segments and examine targeted biopsies of mucosal abnormalities, the Seattle protocol is primarily limited by lack of adherence and increased risk of sampling error. “Moreover, the rates of ‘missed’ dysplasia and EAC [esophageal adenocarcinoma] remain high, with up to a quarter of all EAC being ‘missed,’ ” wrote study authors Don Codipilly, MD, of the Mayo Clinic, and colleagues. The report is in Gastrointestinal Endoscopy.

There are challenges associated with the Seattle protocol, specifically poor protocol adherence and missed identification of subtle abnormalities potentially harboring dysplasia. In contrast, the novel WATS-3D may overcome issues related to sampling error due to its ability to obtain higher proportions of Barrett’s esophagus mucosa through the use of a brush-only technique. According to the researchers, previous studies suggest WATS-3D may increase dysplasia yield by approximately 40% compared with conventional surveillance methods.

To gauge the incremental yield of WATS-3D for dysplasia detection compared with the Seattle forceps biopsy protocol, Dr. Codipilly and colleagues performed a systematic review and meta-analysis of seven studies using the two techniques from 2000 to 2020. The researchers defined “incremental yield” of detected dysplasia as a composite of indefinite for dysplasia, low-grade dysplasia, high-grade dysplasia (HGD), and esophageal adenocarcinoma (EAC). They also compared the two surveillance techniques in terms of incremental yields of HGD/EAC, as well as the rate of reconfirmation of WATS-3D dysplasia on subsequent forceps biopsies.

The seven studies in the final analysis included a pooled cohort of 3,206 patients. According to the meta-analysis, forceps biopsies diagnosed dysplasia in 15.9% (95% confidence interval, 5.4-30.5) of all cases, while the incremental yield of WATS-3D was 7.2% (95% CI, 3.9-11.5). In the pooled analysis of six studies that reported the secondary outcomes, forceps biopsies diagnosed HGD/EAC in 2.3% (95% CI, 0.6-5.1) of patients, while the incremental yield with WATS-3D was 2.1% (95% CI, 0.4-5.3). The researchers point out that WATS-3D was negative in 62.5% of cases where forceps biopsies detected dysplasia. Reports from two of the studies reconfirmed WATS-3D dysplasia with forceps biopsies histology in 20 patients.

“Based on these findings, it cannot be recommended to replace the Seattle Protocol but instead to use both techniques in conjunction to detect dysplasia most effectively,” Omar Awais, DO, assistant professor of surgery in the Department of Cardiothoracic Surgery at the University of Pittsburgh School of Medicine, said in an email to this news organization.

Dr. Awais, who was not involved in the meta-analysis, suggests further prospective, randomized studies are needed to confirm the results. “Additionally, we will also need studies to show cost-effectiveness for using WATS-3D in addition to Seattle protocol, as these may help verify WATS-3D dysplasia by standard endoscopic protocol and show we are not missing dysplasia using the technique,” he said.

Felice H. Schnoll-Sussman, MD, professor of clinical medicine and director of the Jay Monahan Center for Gastrointestinal Health at New York–Presbyterian Hospital/Weill Medical College, added that the meta-analysis “adds to our understanding” of the place of WATS as an adjunct approach in dysplasia detection. “In spite of the rigid selection of studies, this analysis also leaves us with questions about the overall utility of WATS given the lack of follow-up cases where dysplasia was only identified on the WATS brush as well as the overall cost-effectiveness of this approach,” she said.

A new study has found that patients with psoriasis who were treated with biologics were more likely to develop psoriatic arthritis (PsA) than those treated with phototherapy, oral therapy, or no therapy at all, although the authors cautioned readers to consider potential biases when reviewing their findings.

“We do not suggest that these results should be interpreted causally; in other words, biologics likely do not cause PsA,” Elana Meer of the University of Pennsylvania, Philadelphia, and coauthors wrote. The study was published in Annals of the Rheumatic Diseases.

Three studies in dermatology clinic-based populations published this past summer – one from Italy, one from Argentina, and one from Israel – suggested that biologics can decrease a psoriasis patient’s risk of developing PsA. To further assess the impact of treatment with biologics, Ms. Meer and associates retrospectively examined the health records of thousands of patients with psoriasis between the ages of 16 and 90 who were initiating therapy. All told, data from 193,709 patients with psoriasis and without PsA who were treated between 2006 and 2017 were gathered from the OptumInsights Electronic Health Record Database.

A total of 14,569 patients from that cohort initiated biologic therapy while 20,321 patients initiated either oral therapy or phototherapy. The mean age in the biologics group was 45.9 years, compared with 49.8 years in the oral and phototherapy group.

The incidence of PsA across all patients was 9.75 cases per 1,000 person-years, compared with 77.26 among the biologic group, 61.99 among the oral therapy group, 26.11 among the phototherapy group, and 5.85 among those who did not receive therapy. After a multivariable adjustment in which biologics were a time-varying exposure, receiving biologics was associated with a higher incidence of PsA (hazard ratio, 4.48; 95% confidence interval, 4.23-4.75). In a model where time starts at the first use of biologics, the incidence was lower – but still notable – after multivariable adjustment (HR, 2.14; 95% CI, 2.00-2.28) and propensity score matching (HR, 2.17; 95% CI, 2.03-2.33).

Bias likely plays a large role in retrospective PsA study

“We’ve been struggling for the last several years to find a database that allows us to really address this question retrospectively,” study coauthor Christopher T. Ritchlin, MD, of the University of Rochester (N.Y.), said in an interview. “It looks like the model you use for a retrospective analysis heavily influences what you come out with.”

He described the potential biases they identified, including the possibility of protopathic bias indicating that patients being treated with biologics who then report joint pain have developed PsA – and are coded accordingly after visiting a rheumatologist.

“This has convinced us that you have to do a prospective study,” he said. “We’ve known that there were flaws with previous studies in this area. We tried to overcome them with our methodology, but there’s no way you can overcome a coding issue when you’re looking at such a large database.”

He noted another likely bias: The patients who are more likely to develop PsA are the ones with severe psoriasis, and they are also the patients most likely to be prescribed biologics.

“In my clinical experience, I have seen many patients develop psoriatic arthritis while on biologics for their psoriasis,” coauthor Joel M. Gelfand, MD, of the University of Pennsylvania, added in an interview. “Currently, we do not have adequate data to recommend treating psoriasis with a particular modality in order to prevent psoriatic arthritis. This question, however, is very important to patients and clinicians and ultimately is best answered with a large-scale pragmatic trial.”

Dr. Ritchlin reported that a prospective study in which “patients with psoriasis who do not have arthritis but do have certain risk factors and abnormal findings on musculoskeletal ultrasounds” will be treated with either biologic agents or placebo is about to begin, with a goal of “either attenuating or preventing the onset of PsA.”

The authors recognized their study’s additional limitations, including electronic health records being used as the primary data source and the possibility that medications were prescribed but never filled. That said, they did attempt to address the latter by using two prescriptions for a given therapy as the primary analysis, “suggesting a refill was initiated.”

The authors said that no commercial entities provided support for the study. Two of the authors acknowledged receiving funding from the National Psoriasis Foundation, and several authors declared potential conflicts of interests that included consulting and receiving honoraria from various pharmaceutical companies.

Background: In 2011, the Accreditation Council for Graduate Medical Education (ACGME) enacted a consecutive work-hour restriction of 16 hours for first-year residents. Reports of these changes have focused on patient safety, resident education, and resident well-being. The impact on resident safety had not been addressed.

While this large, well-powered study suggests extended work-hour restrictions for resident physicians improve their safety, the study is limited by self-reporting of resident physicians. As the ACGME has re-introduced extended duration shifts for first-year resident physicians, hospitalists should advocate for objective physician safety studies in relation to extended-hour shifts.

Bottom line: The 2011 ACGME work-hour reform for first-year physicians improved their safety and health.

Armed with pediatric data from the COVID-19 pandemic, a team of researchers is suggesting that most cases of Guillain-Barré syndrome may not be connected to infectious disease, as is sometimes assumed.

While pediatric cases of various types of infections fell by 45%-95% during the early months of the pandemic, cases of acute inflammatory demyelinating polyneuropathy (AIDP), an inflammatory neuropathy belonging to the clinical spectrum of Guillain-Barré syndrome, only fell by about 32%-37%, a rate that’s similar to the 35.1% decline in overall hospital admissions over that time period, researchers found. There was also no apparent link between the appearance of COVID-19 and the number of reported AIDP cases.

“There was no clear association between respiratory or gastrointestinal infections and rates of AIDP. Further, we found that AIDP did not have the expected dramatic reduction when community-acquired infections decreased during the pandemic,” Children’s Hospital of Philadelphia neurologist Craig A. Press, MD, PhD, said in an interview.

Dr. Press and colleagues presented their findings in a poster at the 50th annual meeting of the Child Neurology Society.

According to Dr. Press, the cause of AIDP in most patients is unclear, although infections and vaccinations are often linked to cases. “However, the data supporting this link is often weak. Infections with Campylobacter jejuni [bacteria that causes food poisoning] are known to be associated with AIDP, while rates of AIDP in the general population and in those with influenza are similar.”

For the new multicenter, cross-sectional study, researchers tracked AIDP data from the 47 pediatric hospitals that provide statistics to the Pediatric Health Information System. They focused on the period from January 2017 to September 2020, which included the first months of the COVID-19 pandemic in the United States.

“Social distancing, masks, and increased hand hygiene decrease community-acquired infectious rates in a dramatic way,” Dr. Press said. “If these infections were causing AIDP, we hypothesized that the cases of AIDP would drop substantially as a result.”

But this didn’t appear to happen. Researchers found that the numbers of various types of infections declined from April to September 2020: Respiratory infections dipped by 73%-78%, gastrointestinal infections fell by 45%-61%, and influenza infections dipped by 88%-95%. But AIDP cases didn’t fall as precipitously. In fact, their levels were about the same as they were in April 2017, a month when rates of gastrointestinal, respiratory disease and influenza infections were at seasonally low – but not abnormal – ebbs.

“While we must be cautious interpreting the results,” Dr. Press said, “this makes the link between infections as the main driver of pediatric AIDP less likely.”

However, he said, “this study does not exclude the possibility that rare infections cause AIDP – the data supporting that some more rare infections like campylobacter have a connection to AIDP are more robust – or that common infections very rarely lead to AIDP. While we look for triggers causing inflammatory disorders, AIDP maybe an autoinflammatory disorder without a clear trigger.”

Going forward, Dr. Press said, “we hope to look at infectious data in a more granular way to identify if specific viral or bacterial infectious may be associated with this or other inflammatory disorders. We believe that the use of data like this and the natural experiment that COVID-19 provided may help us to explore the impact of infections on disorders thought to be postinfectious.”

Children and young adults with epilepsy had fewer seizures after combination treatment with the drug Epidiolex, which contains the cannabidiol (CBD), and various doses of tetrahydrocannabinol (THC), the component of cannabis that makes people high in larger quantities, researchers reported.

“THC can contribute to seizure control and mitigation some of the side effects of CBD,” said study coauthor and Austin, Tex., child neurologist Karen Keough, MD, in an interview. Dr. Keough and colleagues presented their findings at the 50th annual meeting of the Child Neurology Society.

In a landmark move, the Food and Drug Administration approved Epidiolex in 2018 for the treatment of seizures in two rare forms of epilepsy, Lennox-Gastaut syndrome and Dravet syndrome. The agency had never before approved a drug with a purified ingredient derived from marijuana.

CBD, the active ingredient in Epidiolex, is nonpsychoactive. The use in medicine of THC, the main driver of marijuana’s ability to make people stoned, is much more controversial.

Dr. Keough said she had treated 60-70 children with CBD, at the same strength as in Epidiolex (100 mg), and 5 mg of THC before the drug was approved. “I was seeing some very impressive results, and some became seizure free who’d always been refractory,” she said.

When the Epidiolex became available, she said, some patients transitioned to it and stopped taking THC. According to her, some patients fared well. But others immediately experienced worse seizures, she said, and some developed side effects to Epidiolex in the absence of THC, such as agitation and appetite suppression.
 

Combination therapy

For the new study, a retrospective, unblinded cohort analysis, Dr. Keough and colleagues tracked patients who received various doses of CBD, in some cases as Epidiolex, and various doses of THC prescribed by the Texas Original Compassionate Cultivation dispensary, where she serves as chief medical officer.

The initial number of patients was 212; 135 consented to review and 10 were excluded for various reasons leaving a total of 74 subjects in the study. The subjects, whose median age at the start of the study was 12 years (range, 2-25 years), were tracked from 2018 to2021. Just over half (55%) were male, and they remained on the regimen for a median of 805 days (range, 400-1,141).

Of the 74 subjects, 45.9% had a reduction of seizures of more than 75%, and 20.3% had a reduction of 50%-75%. Only 4.1% saw their seizures worsen.

The THC doses varied from none to more than 12 mg/day; CBD doses varied from none to more than 26 mg/kg per day. O the 74 patients, 18 saw their greatest seizure reduction from baseline when they received no THC; 12 saw their greatest seizure reduction from baseline when they received 0-2 mg/kg per day of CBD.
 

Still controversial

Did the patients get high? In some cases they did, Dr. Keough said. However, “a lot of these patients are either too young or too cognitively limited to describe whether they’re feeling intoxicated. That’s one of the many reasons why this is so controversial. You have to go into this with eyes wide open. We’re working in an environment with limited information as to what an intoxicating dose is for a small kid.”

However, she said, it seems clear that “THC can enhance the effect of CBD in children with epilepsy” and reduce CBD side effects. It’s not surprising that the substances work differently since they interact with brain cells in different ways, she said.

For neurologists, she said, “the challenge is to find a reliable source of THC that you can count on and verify so you aren’t overdosing the patients.”

University of Saskatchewan, Saskatoon, child neurologist and cannabinoid researcher Richard Huntsman, MD, who’s familiar with the study findings, said in an interview that they “provide another strong signal that the addition of THC provides benefit, at least in some patients.”

But it’s still unclear “why some children respond best in regards to seizure reduction and side effect profile with combination CBD:THC therapy, and others seemed to do better with CBD alone,” he said. Also unknown: “the ideal THC:CBD ratio that allows optimal seizure control while preventing the potential harmful effects of THC.”

As for the future, he said, “as we are just scratching the surface of our knowledge about the use of cannabis-based therapies in children with neurological disorders, I suspect that the use of these therapies will expand over time.”

Children and young adults with epilepsy had fewer seizures after combination treatment with the drug Epidiolex, which contains the cannabidiol (CBD), and various doses of tetrahydrocannabinol (THC), the component of cannabis that makes people high in larger quantities, researchers reported.
