Bone-modifying agents — most notably denosumab — are often prescribed to prevent skeletal-related complications in patients with metastatic castration-sensitive prostate cancer, but the drugs are not recommended for this indication and can lead to severe toxicities.

How much does Medicare spend each year on non-recommended bone therapy?

The answer, according to a new analysis in JCO Oncology Practice, is more than $44 million, with about $43 million coming from denosumab alone.

Overall, this study found that “the Medicare program pays tens of millions of dollars each year” for bone-modifying agents in patients with metastatic castration-sensitive prostate cancer, “which is not effective and may cause side effects,” lead author Aaron Mitchell, MD, MPH, a medical oncologist at Memorial Sloan Kettering Cancer Center, New York City, and colleagues concluded.

“These findings suggest reducing bone agent overuse could be a rare healthcare ‘win-win.’ Lower costs AND improved patient outcomes,” tweeted Dr. Mitchell. “If I were a payer, I’d be paying attention!”
 

In Prostate Cancer, Bone-Modifying Drug Indications Vary

Bone-modifying drugs are indicated for some patients with prostate cancer.

The American Society of Clinical Oncology has endorsed guidelines that recommend the use of denosumab in men with nonmetastatic prostate cancer at high risk for fracture while taking androgen deprivation therapy.

Among men with metastatic castration-resistant prostate cancer, guidelines also recommend zoledronic acid or denosumab for preventing or delaying skeletal-related events, such as pathologic fractures and spinal cord compression.

For patients with metastatic castration-sensitive disease, however, the bone-modifying agents show no benefit in preventing skeletal-related events and are not recommended for that indication.

In this population, “treatment with bone agents results only in avoidable toxicity and financial cost,” Dr. Mitchell tweeted. In its higher-dose formulation, denosumab comes with a price tag of approximately $40,000 per year in the United States.

An earlier study from Dr. Mitchell and colleagues revealed that the use of bone-modifying drugs to prevent skeletal events in metastatic castration-sensitive prostate cancer is common.

To better understand the costs associated with this inappropriate use, the researchers reviewed Surveillance, Epidemiology, and End Results Program Medicare data from 2011 to 2015. The team identified the frequency and number of doses of zoledronic acid and denosumab prescribed against recommendations in the metastatic castration-sensitive setting, making sure to distinguish between the use of denosumab to prevent osteoporotic fractures (appropriate use) and to prevent skeletal-related events (non-recommended use).

The team found that, among 2627 patients with metastatic castration-sensitive prostate cancer, 42% received at least one dose of denosumab and 18% received at least one dose of zoledronic acid.

The authors also found that unnecessary use of these drugs increased over time — with a little over 17% of patients receiving zoledronic acid between 2007 and 2009 and just over 28% receiving either denosumab (20.3%) or zoledronic acid (8.4%) from 2012 to 2015.

The annual costs to Medicare from non-recommended prescribing came to $44,105,041 for both agents, with the costs associated with denosumab representing the lion’s share at $43,303,078.

Non-recommended use of these agents also came with adverse events, such as femur fracture and hypocalcemia, which cost an estimated $758,450 to treat annually — $682,865 for denosumab and $75,585 for zoledronic acid.

The study focused on the Medicare-age population, which means the estimates are conservative. “Denosumab overuse for younger patients with castration-sensitive prostate cancer would add substantially to this total,” the authors wrote.

“This study contributes new evidence of overuse in the metastatic castrate-sensitive prostate cancer setting, which I must admit reflects my clinical experience in seeing patients for second opinions who are treated in the community,” said Samuel U. Takvorian, MD, of the Division of Hematology and Oncology, Perelman School of Medicine, Philadelphia, who wasn’t involved in the research. “While there are some circumstances in which one would consider using a bone-modifying agent in the metastatic castrate-sensitive prostate cancer setting, most [of these] men don’t need them upfront.”
 

Why Is the Overuse Happening?

One reason for the inappropriate use of bone-modifying drugs could be confusion surrounding the recommendations because the drugs are recommended for some patients with prostate cancer.

Michael R. Laurent, MD, PhD, of Imelda Hospital, Bonheiden, Belgium, explained that the use of bone-modifying drugs is, paradoxically, often overlooked in settings where they are recommended — when patients have an elevated risk for osteoporosis or fracture.

“Guidelines are quite unequivocal in their recommendations to prevent osteoporosis in mostly older men who receive androgen deprivation therapy,” but “I think there is significant undertreatment” in these patients, Dr. Laurent told this news organization.

However, the recommendation for patients at risk for osteoporosis or bone fracture calls for less intense regimens, which may include lower-dose denosumab, administered once every 6 months, zoledronic acid, given yearly, or another lower potency agent, such as oral alendronate weekly, explained Philip J. Saylor, MD, an attending physician at Massachusetts General Hospital and assistant professor at Harvard Medical School, Boston.

Meanwhile, “monthly high-intensity therapy to prevent skeletal events should be reserved specifically for bone metastatic castration-resistant prostate cancer for more than just cost reasons,” Dr. Saylor said.

When it comes to the higher dose, monthly therapy in castration-sensitive prostate cancer, “we have no evidence that it is beneficial,” he said, adding that “when the prostate cancer itself is well controlled by hormonal therapy, there just aren’t very many pathologic fractures or other bone complications.”

Alongside possible confusion over the recommendations, many physicians also likely don’t know how much denosumab costs.

“In our recent physician interview study, we did find that most physicians were very much unaware of the cost of this drug, or the cost difference between denosumab and zoledronic acid, so I do think that lack of cost awareness is a factor,” Dr. Mitchell said.

Part of the reason may be how Medicare covers these agents. Typically, Medicare would not cover non-recommended indications, but “in this case, Medicare coverage is broader and includes both the guideline-recommended and non-recommended uses,” Dr. Mitchell explained.

However, the authors also identified a more cynical reason for non-recommended prescribing — promotional payments from drug makers to physicians.

In another recent paper, Dr. Mitchell said he found about “30% of doctors treating prostate cancer had received payments from Amgen for Xgeva [denosumab] promotion during the last year.”

These payments appeared to influence non-recommended prescribing: Among patients whose doctor had not received payments, 31.4% received non-recommended denosumab, which increased to nearly 50% of patients among doctors who had received payments.

Dr. Mitchell suggested a few ways to help curb inappropriate prescribing.

Medicare could, for instance, change its coverage policy to include only the recommended uses of these agents, Dr. Mitchell said.

More physician education would be another solution. “I think that physician education would be one ‘bottom-up’ approach that could work,” Dr. Mitchell added.

Dr. Mitchell, Dr. Takvorian, and Dr. Saylor had no disclosures to report. Dr. Laurent has received lecture and consultancy fees from Alexion, AM Pharma, Amgen, Galapagos, Kyowa Kirin, Menarini, Orifarm, Pharmanovia, Takeda, UCB, and Will Pharma.

Thanks to decades of successful vector control strategies, vector-borne transmission of Chagas disease has significantly decreased in many regions. Oral ingestion of Trypanosoma cruzi through contaminated food and beverages, however, is increasing. Unlike vector transmission, oral transmission of Chagas disease entails high lethality in pediatric and adult populations.

“The oral transmission of Chagas disease is becoming a much more recognized route, and it is crucial to understand that people can die from this type of transmission,” Norman L. Beatty, MD, assistant professor of infectious diseases and global medicine at the University of Florida College of Medicine in Gainesville, Florida, told this news organization. Dr. Beatty is the lead author of a recent article on the subject.

In regions where the parasite circulates in the environment, people are consuming foods, fruit juices, and possibly wild animal meat that may be contaminated. “As we experience changes in our environment and in the way we consume food, it is crucial to consider how food preparation is carried out in areas where T cruzi transmission occurs in the environment,” said Dr. Beatty. “And as organic farming methods without insecticides become increasingly common, more research is needed in these areas, both in Latin America and in the United States, to understand if oral transmission of T cruzi is occurring.”

In the Amazon basin, foodborne transmission is already the leading cause of acute Chagas disease. It has been described in Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, and Venezuela.

Dr. Beatty’s colleagues recently treated a Brazilian patient at the hospital in Florida. “He came to our hospital very ill, with acute myocarditis after consuming contaminated açaí.” Clarifying that there is widespread awareness about oral transmission in Brazil, he stated, “We are concerned that it may not be recognized in other areas of Latin America.”

Mexico and regions of Central America have little to no information on oral transmission, but it is likely occurring, and cases may be going undetected in the region, said Dr. Beatty.

He investigated the issue in Colombia as part of an international collaboration involving the University of Antioquia, aiming to find ways to mitigate oral transmission and create a model that can be used throughout Latin America and the United States. For the Colombia study, they reviewed all cases reported to the Ministry of Health and Social Protection, and oral transmission turned out to be more common than the research group expected. “Still, I imagine that in certain areas with limited resources…there are many more cases that are not being reported.

“A myth I would like to dispel is that Chagas disease is not being transmitted in the United States,” Dr. Beatty added. He mentioned that at least 30 American states have vectors, and in Florida, it was documented that triatomines invaded homes and bit residents. In addition, 30% of these insects are infected with T cruzi. Research is underway to determine whether Floridians are becoming infected and if they are also at risk of contracting Chagas disease orally, said Dr. Beatty. “In the United States, we know very little about how many people are infected and what the infection routes are. Much more research is needed.”

Roberto Chuit, MD, PhD, a doctor in public health and an external consultant for the Pan American Health Organization (PAHO), agreed that this route of food contamination, which occurs because of vector-borne parasites, was until recently masked or hidden by the predominance of vector presence. Just as it began to gain importance as other transmission routes were controlled, “it now has extremely high importance in the Americas, as does vertical transmission,” he said.

In 2023, more than 50 years after the first description of oral transmission, the PAHO expert meeting proposed to alert health services and the broader community about the severity and potential lethality of oral Chagas disease outbreaks to elicit immediate responses and mitigation measures. The body also proposed conducting studies to provide detailed information on the contamination source and the wild vectors present in oral transmission foci.
 

Unique Clinical Manifestations

The exacerbated signs and symptoms of oral infection (see sidebar) are attributed to the high parasite loads in contaminated food and beverages. A single crushed triatomine along with a food or beverage harboring T cruzi can contain an estimated 600,000 metacyclic trypomastigotes, compared with 3000-4000 per µL when infection occurs by triatomine fecal matter. The robust systemic immune response observed in patients with acute oral Chagas disease is thought to result from more efficient transmission after penetration through the oral, pharyngeal, and gastric mucosae.
 

Seven Things to Know About Orally Transmitted Chagas Disease

1. It presents with exacerbated symptoms and rapid disease progression in immunocompetent individuals. This presentation is not common in vector-borne, congenital, or transfusion-related transmission. It can cause fulminant myocarditis and heart failure, meningoencephalitis, or potentially fatal shock due to parasitemia.

2. Most patients (71%-100%) with acute oral Chagas present with fever.

3. Electrocardiographic abnormalities, specifically ventricular depolarization alterations and pericardial involvement, are observed in most patients.

4. Facial edema, which typically affects the entire face and parts of the lips, is present in 57%-100% of patients with acute oral Chagas disease. In those with acute symptoms from vector transmission, unilateral periorbital swelling (Romaña’s sign) is more common.

5. Other notable systemic symptoms include edema of the lower extremities, myalgia, generalized lymphadenopathy, abdominal discomfort, dyspnea, vomiting, diarrhea, hepatomegaly, splenomegaly, headache, chest pain, cutaneous erythematous rash, jaundice, arthralgia, epistaxis, hematemesis, melena, and palpitations.

6. The incubation period after oral ingestion of products contaminated with Trypanosoma cruzi is approximately 3-22 days, in contrast to 4-15 days for vector-borne transmission and 8-160 days for transfusion and transplant-related transmission.

7. Patients need antiparasitic drugs immediately.
 

Thinking Epidemiologically

Dr. Chuit recalled that suspicion of food contamination should be based on epidemiology, especially in outbreaks affecting several people and in regions where Chagas vectors have been described. Sometimes, however, a single careless tourist consumes contaminated products.

“The difficulty is that many times it is not considered, and if it is not considered, the search for the parasite is not requested,” said Dr. Chuit. He added that it is common for the professional to consider Chagas disease only if viral and bacterial isolation tests are negative. Clinicians sometimes consider Chagas disease because the patient has not responded to regular treatments for other causes, such as antibiotics and hydration.

Epidemiology is important, especially when Chagas disease is diagnosed in groups or a family, because they are usually not isolated cases but outbreaks of 3-40 cases, according to Dr. Chuit. “Under these conditions, it must be quickly considered…that this parasite may be involved.”

One of the difficulties is that the source of these oral transmissions is not recognized most of the time. In general, the sources are usually foods that are more likely to be contaminated by insects or insect feces, such as orange juice or sugarcane. But in fact, any food or beverage left unattended could be contaminated by vectors or possible secretions from infected marsupial odoriferous glands.

An analysis of 32 outbreaks from 1965 to 2022 showed that the main foods involved in oral transmission were homemade fruit juices. But different vector species were identified, and the reservoirs were mainly dogs, rodents, and large American opossums (Didelphis).

The largest oral Chagas outbreak was linked to the consumption of contaminated guava juice in a primary school in Caracas, Venezuela. Nonindustrially produced açaí is a common source of orally acquired Chagas disease in Brazil. In Colombia, Chagas disease has been associated with the consumption of palm wine, sugar cane, and tangerine juice. Other oral transmission routes include consuming meat from wild animals and ingesting blood from infected armadillos, which is related to a traditional medicine practice.
 

Deadly Yet Easily Treatable

In the outbreak of 119 confirmed and suspected cases in Venezuela, 20.3% required hospitalization, and a 5-year-old child died of acute myocarditis. These percentages differ from those reported in vector transmission, which is asymptomatic in the acute phase for 95%-99% of cases or will only develop a mild febrile illness that resolves on its own.

“Not all cases will present as severe, because depending on the inoculum, there may be individuals with subclinical situations. But any food poisoning that occurs in endemic areas, where food is not properly controlled, and these street foods are associated with processes in jungle areas, raises the possibility that T cruzi is involved and should be considered as a differential diagnosis,» noted Dr. Chuit. “The treatment is highly effective, and people recover quickly.”

“The most important thing about oral transmission of Chagas is that someone infected in this way needs antiparasitic drugs immediately. We can cure them if we treat them immediately,” said Dr. Beatty, adding that treatment is sometimes delayed due to lack of access to appropriate antiparasitic drugs. “Here in the United States and in Latin America, it is quite common for healthcare professionals not to understand the differences between vector, vertical, and oral transmission. By not treating these patients, they become ill quickly.”

Dr. Beatty and Dr. Chuit declared no relevant financial conflicts of interest.

Roberto Chuit, MD, PhD, a doctor in public health and an external consultant for the Pan American Health Organization (PAHO), agreed that this route of food contamination, which occurs because of vector-borne parasites, was until recently masked or hidden by the predominance of vector presence. Just as it began to gain importance as other transmission routes were controlled, “it now has extremely high importance in the Americas, as does vertical transmission,” he said.

In 2023, more than 50 years after the first description of oral transmission, the PAHO expert meeting proposed to alert health services and the broader community about the severity and potential lethality of oral Chagas disease outbreaks to elicit immediate responses and mitigation measures. The body also proposed conducting studies to provide detailed information on the contamination source and the wild vectors present in oral transmission foci.
 

Unique Clinical Manifestations

The exacerbated signs and symptoms of oral infection (see sidebar) are attributed to the high parasite loads in contaminated food and beverages. A single crushed triatomine along with a food or beverage harboring T cruzi can contain an estimated 600,000 metacyclic trypomastigotes, compared with 3000-4000 per µL when infection occurs by triatomine fecal matter. The robust systemic immune response observed in patients with acute oral Chagas disease is thought to result from more efficient transmission after penetration through the oral, pharyngeal, and gastric mucosae.
 

Seven Things to Know About Orally Transmitted Chagas Disease

1. It presents with exacerbated symptoms and rapid disease progression in immunocompetent individuals. This presentation is not common in vector-borne, congenital, or transfusion-related transmission. It can cause fulminant myocarditis and heart failure, meningoencephalitis, or potentially fatal shock due to parasitemia.

2. Most patients (71%-100%) with acute oral Chagas present with fever.

3. Electrocardiographic abnormalities, specifically ventricular depolarization alterations and pericardial involvement, are observed in most patients.

4. Facial edema, which typically affects the entire face and parts of the lips, is present in 57%-100% of patients with acute oral Chagas disease. In those with acute symptoms from vector transmission, unilateral periorbital swelling (Romaña’s sign) is more common.

5. Other notable systemic symptoms include edema of the lower extremities, myalgia, generalized lymphadenopathy, abdominal discomfort, dyspnea, vomiting, diarrhea, hepatomegaly, splenomegaly, headache, chest pain, cutaneous erythematous rash, jaundice, arthralgia, epistaxis, hematemesis, melena, and palpitations.

6. The incubation period after oral ingestion of products contaminated with Trypanosoma cruzi is approximately 3-22 days, in contrast to 4-15 days for vector-borne transmission and 8-160 days for transfusion and transplant-related transmission.

7. Patients need antiparasitic drugs immediately.
 

Thinking Epidemiologically

Dr. Chuit recalled that suspicion of food contamination should be based on epidemiology, especially in outbreaks affecting several people and in regions where Chagas vectors have been described. Sometimes, however, a single careless tourist consumes contaminated products.

“The difficulty is that many times it is not considered, and if it is not considered, the search for the parasite is not requested,” said Dr. Chuit. He added that it is common for the professional to consider Chagas disease only if viral and bacterial isolation tests are negative. Clinicians sometimes consider Chagas disease because the patient has not responded to regular treatments for other causes, such as antibiotics and hydration.

Epidemiology is important, especially when Chagas disease is diagnosed in groups or a family, because they are usually not isolated cases but outbreaks of 3-40 cases, according to Dr. Chuit. “Under these conditions, it must be quickly considered…that this parasite may be involved.”

One of the difficulties is that the source of these oral transmissions is not recognized most of the time. In general, the sources are usually foods that are more likely to be contaminated by insects or insect feces, such as orange juice or sugarcane. But in fact, any food or beverage left unattended could be contaminated by vectors or possible secretions from infected marsupial odoriferous glands.

An analysis of 32 outbreaks from 1965 to 2022 showed that the main foods involved in oral transmission were homemade fruit juices. But different vector species were identified, and the reservoirs were mainly dogs, rodents, and large American opossums (Didelphis).

The largest oral Chagas outbreak was linked to the consumption of contaminated guava juice in a primary school in Caracas, Venezuela. Nonindustrially produced açaí is a common source of orally acquired Chagas disease in Brazil. In Colombia, Chagas disease has been associated with the consumption of palm wine, sugar cane, and tangerine juice. Other oral transmission routes include consuming meat from wild animals and ingesting blood from infected armadillos, which is related to a traditional medicine practice.
 

Deadly Yet Easily Treatable

In the outbreak of 119 confirmed and suspected cases in Venezuela, 20.3% required hospitalization, and a 5-year-old child died of acute myocarditis. These percentages differ from those reported in vector transmission, which is asymptomatic in the acute phase for 95%-99% of cases or will only develop a mild febrile illness that resolves on its own.

“Not all cases will present as severe, because depending on the inoculum, there may be individuals with subclinical situations. But any food poisoning that occurs in endemic areas, where food is not properly controlled, and these street foods are associated with processes in jungle areas, raises the possibility that T cruzi is involved and should be considered as a differential diagnosis,» noted Dr. Chuit. “The treatment is highly effective, and people recover quickly.”

“The most important thing about oral transmission of Chagas is that someone infected in this way needs antiparasitic drugs immediately. We can cure them if we treat them immediately,” said Dr. Beatty, adding that treatment is sometimes delayed due to lack of access to appropriate antiparasitic drugs. “Here in the United States and in Latin America, it is quite common for healthcare professionals not to understand the differences between vector, vertical, and oral transmission. By not treating these patients, they become ill quickly.”

Dr. Beatty and Dr. Chuit declared no relevant financial conflicts of interest.

Thanks to decades of successful vector control strategies, vector-borne transmission of Chagas disease has significantly decreased in many regions. Oral ingestion of Trypanosoma cruzi through contaminated food and beverages, however, is increasing. Unlike vector transmission, oral transmission of Chagas disease entails high lethality in pediatric and adult populations.

“The oral transmission of Chagas disease is becoming a much more recognized route, and it is crucial to understand that people can die from this type of transmission,” Norman L. Beatty, MD, assistant professor of infectious diseases and global medicine at the University of Florida College of Medicine in Gainesville, Florida, told this news organization. Dr. Beatty is the lead author of a recent article on the subject.

In regions where the parasite circulates in the environment, people are consuming foods, fruit juices, and possibly wild animal meat that may be contaminated. “As we experience changes in our environment and in the way we consume food, it is crucial to consider how food preparation is carried out in areas where T cruzi transmission occurs in the environment,” said Dr. Beatty. “And as organic farming methods without insecticides become increasingly common, more research is needed in these areas, both in Latin America and in the United States, to understand if oral transmission of T cruzi is occurring.”

In the Amazon basin, foodborne transmission is already the leading cause of acute Chagas disease. It has been described in Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, and Venezuela.

Dr. Beatty’s colleagues recently treated a Brazilian patient at the hospital in Florida. “He came to our hospital very ill, with acute myocarditis after consuming contaminated açaí.” Clarifying that there is widespread awareness about oral transmission in Brazil, he stated, “We are concerned that it may not be recognized in other areas of Latin America.”

Mexico and regions of Central America have little to no information on oral transmission, but it is likely occurring, and cases may be going undetected in the region, said Dr. Beatty.

He investigated the issue in Colombia as part of an international collaboration involving the University of Antioquia, aiming to find ways to mitigate oral transmission and create a model that can be used throughout Latin America and the United States. For the Colombia study, they reviewed all cases reported to the Ministry of Health and Social Protection, and oral transmission turned out to be more common than the research group expected. “Still, I imagine that in certain areas with limited resources…there are many more cases that are not being reported.

“A myth I would like to dispel is that Chagas disease is not being transmitted in the United States,” Dr. Beatty added. He mentioned that at least 30 American states have vectors, and in Florida, it was documented that triatomines invaded homes and bit residents. In addition, 30% of these insects are infected with T cruzi. Research is underway to determine whether Floridians are becoming infected and if they are also at risk of contracting Chagas disease orally, said Dr. Beatty. “In the United States, we know very little about how many people are infected and what the infection routes are. Much more research is needed.”

TOPLINE:

More than a billion children, adolescents, and adults are living with obesity, globally, with rates of obesity among children and adolescents quadrupling between 1990 and 2022.

Obesity rates nearly tripled among adult men and more than doubled among women during the time period, according to results from a collaboration between the NCD Risk Factor Collaboration and the World Health Organization (WHO).

The rates of being underweight have meanwhile declined, making obesity now the most common form of malnutrition in most regions.

METHODOLOGY:

In this global analysis, the authors evaluated 3663 population-based studies conducted in 200 countries and territories, with data on 222 million participants in the general population, including height and weight.

Trends were established according to categories of body mass index (BMI) in groups of adults aged 20 years or older, representing 150 million individuals, and 63 million school-aged children and adolescents aged 5-19 years, spanning from 1990 to 2022.

Assessments of adults focus on the individual and combined prevalence of underweight (BMI < 18.5 kg/m²) and obesity (BMI ≥ 30 kg/m²).

For school-aged children and adolescents, assessments were for thinness (BMI < 2 standard deviation [SD] below the median of the WHO growth reference) and obesity (BMI > 2 SD above the median).

TAKEAWAY:

The combined prevalence of obesity as well as underweight increased over the study period in most countries for women (162 countries, 81%) and men (140 countries, 70%), with increases driven by increases in obesity in nearly all countries, while underweight or thinness rates decreased.

In 2022, obesity rates were higher than underweight in 177 countries (89%) for women and 145 countries (73%) for men.

Likewise, among school-aged children and adolescents, obesity in 2022 was more prevalent than thinness among girls in 130 countries (67%) and boys in 125 countries (63%), while thinness was more prevalent in only 18% and 21% of the countries, respectively.

In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, as well as in countries in the Middle East and North Africa.

Among school-aged children, the countries with the highest combined prevalence of underweight and obesity were Polynesia and Micronesia and the Caribbean for both sexes and Chile and Qatar for boys.

The prevalence of obesity surpassed 60% among women in eight countries (4%) and men in six countries (3%), all in Polynesia and Micronesia.

In the United States, the obesity rate increased from 21.2% in 1990 to 43.8% in 2022 for women and from 16.9% to 41.6% in 2022 for men.

As of 2022, the prevalence of obesity in the United States ranked 36th highest in the world for women and 10th highest in the world for men.

IN PRACTICE:

“It is very concerning that the epidemic of obesity that was evident among adults in much of the world in 1990 is now mirrored in school-aged children and adolescents,” senior author Majid Ezzati, PhD, of Imperial College of London, said in a press statement.

“At the same time, hundreds of millions are still affected by undernutrition, particularly in some of the poorest parts of the world,” he said. “To successfully tackle both forms of malnutrition, it is vital we significantly improve the availability and affordability of healthy, nutritious foods.”

Tedros Adhanom Ghebreyesus, PhD, WHO Director-General, added in the press statement that “this new study highlights the importance of preventing and managing obesity from early life to adulthood, through diet, physical activity, and adequate care, as needed.

“Getting back on track to meet the global targets for curbing obesity will take the work of governments and communities, supported by evidence-based policies from WHO and national public health agencies,” he said.

“Importantly, it requires the cooperation of the private sector, which must be accountable for the health impacts of their products.”

The study was published on February 29, 2024, in The Lancet. The study was conducted by the NCD Risk Factor Collaboration and the WHO.

LIMITATIONS:

Data differences in countries included that some had limited data and three had none, requiring some estimates to be formed using data from other countries. Data availability was also lower among the youngest and oldest patients, increasing uncertainty of data in those age groups. In addition, data from health surveys can be subject to error, and BMI can be an imperfect measure of the extent or distribution of body fat.

TOPLINE:

People with diabetes who live in small towns in the United States experience higher rates of complications than those living in cities and remote areas.

METHODOLOGY:

Retrospective cohort study using the OptumLabs Data Warehouse used a deidentified data set of US commercial and Medicare Advantage beneficiaries including 2,901,563 adults with diabetes between 2012 and 2021.

Overall, 2.6% lived in remote areas (population < 2500), 14.1% in small towns (2500-50,000), and 83.3% in cities (> 50,000).

Multivariable analysis adjusted for age, sex, health plan type, index year, diabetes type, baseline comorbidities, and medication use.

TAKEAWAY:

Relative to people living in cities, people in remote areas had significantly greater risks for myocardial infarction (hazard ratio, 1.06) and revascularization (1.04) but lower risks for hypoglycemia (0.90) and stroke (0.91).

Compared with cities, people living in small towns had significantly more hyperglycemia (1.06), hypoglycemia (1.15), end-stage kidney disease (1.04), myocardial infarction (1.10), heart failure (1.05), amputation (1.05), other lower-extremity complications (1.02), and revascularization (1.05), but a lower risk for stroke (0.95).

Compared with small towns, people living in remote areas had lower risks for hyperglycemia (0.85), hypoglycemia (0.92), and heart failure (0.94).

No geographic differences were found for retinopathy or atrial fibrillation/flutter.

The results didn’t differ significantly when the 2.5% overall with type 1 diabetes were removed from the dataset.

IN PRACTICE:

“While more research is needed to better understand the underlying causes of disparate diabetes outcomes along the rural-urban continuum, this study establishes the foundational differences to guide improvement efforts and helps to identify complications with the greatest disparities to which policy interventions may be targeted.”

SOURCE:

The study was conducted by Kyle Steiger, MD, Internal Medicine Residency, Mayo Clinic, Rochester, Minnesota, and colleagues, and published February 22 in Diabetes Care.

LIMITATIONS:

Claims data were from a single national health insurance provider that administers multiple private and Medicare Advantage health plans with disproportionate representation of urban populations and without people who have Medicaid or traditional Medicare fee-for-service or who are without insurance (and would be expected to have higher complication rates). There were no data on race/ethnicity. Potential for residual confounding.

DISCLOSURES:

This study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Steiger had no disclosures.

Compared with cities, people living in small towns had significantly more hyperglycemia (1.06), hypoglycemia (1.15), end-stage kidney disease (1.04), myocardial infarction (1.10), heart failure (1.05), amputation (1.05), other lower-extremity complications (1.02), and revascularization (1.05), but a lower risk for stroke (0.95).

Compared with small towns, people living in remote areas had lower risks for hyperglycemia (0.85), hypoglycemia (0.92), and heart failure (0.94).

No geographic differences were found for retinopathy or atrial fibrillation/flutter.

The results didn’t differ significantly when the 2.5% overall with type 1 diabetes were removed from the dataset.

IN PRACTICE:

“While more research is needed to better understand the underlying causes of disparate diabetes outcomes along the rural-urban continuum, this study establishes the foundational differences to guide improvement efforts and helps to identify complications with the greatest disparities to which policy interventions may be targeted.”

SOURCE:

The study was conducted by Kyle Steiger, MD, Internal Medicine Residency, Mayo Clinic, Rochester, Minnesota, and colleagues, and published February 22 in Diabetes Care.

LIMITATIONS:

Claims data were from a single national health insurance provider that administers multiple private and Medicare Advantage health plans with disproportionate representation of urban populations and without people who have Medicaid or traditional Medicare fee-for-service or who are without insurance (and would be expected to have higher complication rates). There were no data on race/ethnicity. Potential for residual confounding.

DISCLOSURES:

This study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Steiger had no disclosures.

TOPLINE:

People with diabetes who live in small towns in the United States experience higher rates of complications than those living in cities and remote areas.

METHODOLOGY:

Retrospective cohort study using the OptumLabs Data Warehouse used a deidentified data set of US commercial and Medicare Advantage beneficiaries including 2,901,563 adults with diabetes between 2012 and 2021.

Overall, 2.6% lived in remote areas (population < 2500), 14.1% in small towns (2500-50,000), and 83.3% in cities (> 50,000).

Multivariable analysis adjusted for age, sex, health plan type, index year, diabetes type, baseline comorbidities, and medication use.

TAKEAWAY:

Relative to people living in cities, people in remote areas had significantly greater risks for myocardial infarction (hazard ratio, 1.06) and revascularization (1.04) but lower risks for hypoglycemia (0.90) and stroke (0.91).

Tools to screen for spondyloarthritis (SpA) among people with the extra-musculoskeletal conditions that commonly co-occur with SpA — psoriasis, uveitis, and inflammatory bowel disease (IBD) — show potential for their use in target populations but have limited generalizability for patients at risk for SpA, according to findings from a scoping review of 18 tools.

Prior to the review comparing available tools, first author Vartika Kesarwani, MBBS, of the University of Connecticut, Farmington, and colleagues wrote that the performance of SpA screening tools in dermatology, ophthalmology, and gastroenterology contexts had not been evaluated.

“Given the evolving landscape of therapeutics for spondyloarthritis, recognizing the full spectrum of disease manifestations in individual patients becomes increasingly important. This knowledge can inform treatment decisions, potentially altering the course of the disease,” corresponding author Joerg Ermann, MD, of Brigham and Women’s Hospital, Boston, said in an interview.

In the study, published on February 1 in Arthritis Care & Research, the investigators identified 13 SpA screening tools for psoriasis (screening specifically for psoriatic arthritis), two for uveitis, and three for IBD. All tools with the exception of one for uveitis were patient-oriented questionnaires with an average completion time of less than 5 minutes.

Overall, the researchers found significant variability in the nature of the questions used to identify clinical features of SpA; 15 tools included at least one question on back pain or stiffness; 16 tools had at least one question on joint pain, swelling, or inflammation; 10 included questions about heel or elbow pain; and 10 included questions about swelling of digits.

All 13 of the psoriasis tools were screened for peripheral arthritis, while 10 screened for axial involvement, eight screened for enthesitis, and eight screened for dactylitis.

All three of the IBD tools were screened for axial involvement and peripheral arthritis, and two were screened for enthesitis and dactylitis.

Both of the uveitis tools were screened for axial involvement, but neither was screened for peripheral arthritis, enthesitis, or dactylitis.

Sensitivities in the primary validation groups were similar for the 16 tools for which sensitivities were reported, ranging mainly from 82% to 92% for 11 psoriasis tools, 91% to 96% for uveitis tools, and 83% to 93% for IBD tools.

Specificities for psoriasis tools ranged from 69% to 83% for all but two of the tools, which was 46% for one and 35%-89% for another across three geographical cohorts. For uveitis tools, specificities were 91%-97% for uveitis tools, and for IBD tools, 77%-90%. Most of the secondary validations involved psoriasis tools, and these were generally lower and also more variable.
 

The Case for a Generic Tool

The relatively few SpA tools for patients with uveitis and IBD, compared with psoriasis, may be attributable to a lack of awareness of the association between these conditions on the part of ophthalmologists and gastroenterologists, the researchers wrote in their discussion. Therefore, a generic SpA screening tool that could apply to any extra-articular manifestation might increase screening across clinical settings and streamline rheumatology referrals, they noted.

The review’s findings were limited by several factors, including the inclusion of only articles in English and the relatively few tools for uveitis and IBD patients, the researchers noted.

The findings suggested that although the performances of the tools are similar, their degree of variability supports the value of a generic tool, they concluded.
 

Streamlining to Increase Screening

“Compared to the large amount of research in psoriasis and psoriatic arthritis, relatively little has been done with regard to screening for spondyloarthritis in patients with uveitis or IBD,” Dr. Ermann told this news organization. “Despite the numerous screening tools developed for psoriatic arthritis, no ideal screening tool has emerged, and the implementation of effective screening strategies in clinical practice is challenging,” he said. In the current study, the compartmentalization of research into individual conditions like psoriasis, uveitis, and IBD was notable despite the interconnected nature of these conditions with SpA, he added.

In practice, Dr. Ermann advised clinicians to maintain a high index of suspicion for SpA in patients presenting with psoriasis, uveitis, or IBD and proactively ask patients about symptoms outside their primary specialty.

“Future research should focus on developing a universal spondyloarthritis screening tool that is comprehensive, easily understandable, and can be used across various clinical settings,” he said.
 

Need for Early Identification and Closer Collaboration

A delay in SpA diagnosis of as little as 6 months can lead to worse outcomes, Rebecca Haberman, MD, a rheumatologist at NYU Langone Health, New York City, said in an interview. “Patients with these conditions may first present to dermatologists, gastroenterologists, and/or ophthalmologists before rheumatologic evaluation. If we can identify these patients early at this stage, we might be able to improve outcomes, but the question remains of how we get these patients to the proper care,” she said.

The review examined the currently available screening tools for use in patients with psoriasis, IBD, and uveitis and highlights the heterogeneity of these tools in terms of use and disease characteristics, as well as the lack of tools for use in gastroenterology and ophthalmology offices, Dr. Haberman said.

The review “proposes several important ideas, such as creating a unified screening tool that can be used across diseases and fields, to reduce confusion by providers and help provide standardization of the referral process to rheumatologists,” she said.

“Even though SpA is prevalent in many patients with psoriasis, IBD, and uveitis, it remains very underdiagnosed, and often referrals to rheumatologists are not made,” Dr. Haberman told this news organization. Diagnostic challenges likely include SpA’s heterogeneous presentation, the specialists’ lack of knowledge regarding the connection between these conditions and joint disease, and time pressures in clinical settings, she said.

“Other practitioners are not always trained to ask about joint pain and often have limited time in their exams to ask additional questions. To overcome this, more collaboration is needed between dermatologists, gastroenterologists, ophthalmologists, and rheumatologists, as many of our diseases live in the same family,” Dr. Haberman said.

Improving clinician education and creating relationships can help facilitate questions and referrals, she said. Short, effective screening tools that can be filled out by the patient may also help overcome specialists’ discomfort about asking musculoskeletal-related questions and would save time in the clinical visit, she said.

More research is needed to identify the best screening tools and questions and which are the most highly sensitive and specific, Dr. Haberman said. “This will allow for rheumatologists to see patients who may have SpA earlier in their course without overwhelming the system with new referrals.” In addition, more work is needed on how and whether screening tools are being used in clinical practice, not just in research studies, she said.

The study was supported by a grant from the National Institutes of Health/National Institute of Arthritis and Musculoskeletal and Skin Diseases. The researchers and Dr. Haberman had no financial conflicts to disclose.

TOPLINE:

Continued denosumab treatment is associated with a lower risk for diabetes in adults with osteoporosis older than 65 years, found a large-scale cohort study in Taiwan.

METHODOLOGY:

• Denosumab, used in osteoporosis treatment, has been suggested to improve glycemic parameters, but clinical evidence of its effects on diabetes risk is limited and inconsistent.
• Using data from Taiwan’s National Health Insurance Research Database (NHIRD), the study asked if continued denosumab treatment (60 mg) for osteoporosis reduced the risk for diabetes compared to those who discontinued denosumab.
• Researchers included all new users of denosumab between 2012 and 2019 who had no prior history of malignant neoplasms, Paget disease, or diabetes requiring antidiabetic medication.
• Patients in the treatment group (n = 34,255), who received a second dose of denosumab within 225 days, were 1:1 propensity matched with a control group (n = 34,255) of patients who had discontinued denosumab after the first dose.
• The 68,510 patients (mean age, 77.7 years; 84.3% women) were followed up for a mean of 1.9 years. The primary outcome was new-onset diabetes that required treatment with any antidiabetic drug.

TAKEAWAY:

• Continued denosumab treatment vs its discontinuation was associated with a lower risk for incident diabetes (hazard ratio [HR], 0.84; 95% CI, 0.78-0.90).
• In patients aged 65 years or older who were on continued treatment of denosumab, the risk for diabetes was lower (HR, 0.80; 95% CI, 0.75-0.85) but not among those younger than 65 years.
• A reduced risk for diabetes with continued denosumab treatment was observed in both men (HR, 0.85; 95% CI, 0.73-0.97) and women (HR, 0.81; 95% CI, 0.76-0.86).
• Lower diabetes risk with continued denosumab treatment was observed regardless of comorbidities, such as dyslipidemia, hypertension, ischemic heart disease, or kidney failure.

IN PRACTICE:

“Given the high osteoporosis prevalence, the extensive use of antiosteoporosis medications, and the negative effect of diabetes on both patient health and healthcare system burdens in the global aging population, our findings possess substantial clinical and public health significance,” the authors wrote.

SOURCE:

This study was led by Huei-Kai Huang, MD, Department of Family Medicine and Department of Medical Research, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Hualien, Taiwan, and published online in JAMA Network Open.

LIMITATIONS:

The research used claims-based data, so some clinical details, such as lifestyle, substance use, prediabetes weight status, and laboratory results, were not included. Owing to the anonymity policy of the NHIRD, patients could not be directly evaluated to validate incident diabetes. The study included the Taiwanese population, so the findings may not be generalizable to other populations. In Taiwan, the threshold for reimbursement of initiating denosumab treatment for osteoporosis includes below-normal bone density scores and a hip or vertebral fracture.

DISCLOSURES:

This study was supported by grants from the National Science and Technology Council of Taiwan and the National Health Research Institutes of Taiwan and a grant from the Buddhist Tzu Chi Medical Foundation. The corresponding author and a coauthor disclosed receiving funds from Amgen, Novartis, Pfizer, Sanofi, Takeda, and AbbVie, all outside the submitted work.

• A reduced risk for diabetes with continued denosumab treatment was observed in both men (HR, 0.85; 95% CI, 0.73-0.97) and women (HR, 0.81; 95% CI, 0.76-0.86).
• Lower diabetes risk with continued denosumab treatment was observed regardless of comorbidities, such as dyslipidemia, hypertension, ischemic heart disease, or kidney failure.

IN PRACTICE:

“Given the high osteoporosis prevalence, the extensive use of antiosteoporosis medications, and the negative effect of diabetes on both patient health and healthcare system burdens in the global aging population, our findings possess substantial clinical and public health significance,” the authors wrote.

SOURCE:

This study was led by Huei-Kai Huang, MD, Department of Family Medicine and Department of Medical Research, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Hualien, Taiwan, and published online in JAMA Network Open.

LIMITATIONS:

The research used claims-based data, so some clinical details, such as lifestyle, substance use, prediabetes weight status, and laboratory results, were not included. Owing to the anonymity policy of the NHIRD, patients could not be directly evaluated to validate incident diabetes. The study included the Taiwanese population, so the findings may not be generalizable to other populations. In Taiwan, the threshold for reimbursement of initiating denosumab treatment for osteoporosis includes below-normal bone density scores and a hip or vertebral fracture.

DISCLOSURES:

This study was supported by grants from the National Science and Technology Council of Taiwan and the National Health Research Institutes of Taiwan and a grant from the Buddhist Tzu Chi Medical Foundation. The corresponding author and a coauthor disclosed receiving funds from Amgen, Novartis, Pfizer, Sanofi, Takeda, and AbbVie, all outside the submitted work.

A new and deceptively simple advance in chronic stroke treatment could be a vibrating glove.

Researchers at Stanford University and Georgia Tech have developed a wearable device that straps around the wrist and hand, delivering subtle vibrations (akin to a vibrating cellphone) that may relieve spasticity as well as or better than the standard Botox injections.

“The vibro-tactile stimulation can be used at home, and we’re hoping it can be relatively low cost,” said senior study author Allison Okamura, PhD, a mechanical engineer at Stanford University, Stanford, California.

For now, the device is available only to clinical trial patients. But the researchers hope to get the glove into — or rather onto — more patients’ hands within a few years. A recent grant from the National Science Foundation’s Convergence Accelerator program could help pave the way to a commercial product. The team also hopes to expand access in the meantime through larger clinical trials with patients in additional locations.

The work builds on accumulating research exploring vibration and other stimulation therapies as treatments for neurological conditions. Other vibrating gloves have helped reduce involuntary movement for patients with Parkinson’s. And the University of Kansas Medical Center, Kansas City, will soon trial the Food and Drug Administration–approved vagal nerve stimulator, an implantable device intended to treat motor function in stroke survivors. Dr. Okamura noted that devices use “different types of vibration patterns and intensities,” depending on the disease state they target.

Spasticity often develops or worsens months after a stroke. By then, patients may have run out of insurance coverage for rehabilitation. And the effectiveness of Botox injections can “wear out over time,” Dr. Okamura said.

In a clinical trial, patients wore the device for 3 hours a day for 8 weeks, while doing their usual activities. The researchers continued testing their spasticity for 2 more weeks. Symptom relief continued or improved for some patients, even after they stopped using the device. More than half of the participants experienced equal or better results than another group that received only regular Botox injections.
 

How Vibro-Tactile Stimulation May Rewire the Brain

The device originated at Georgia Tech, where Dr. Okamura’s postdoctoral research fellow Caitlyn Seim, PhD, was using vibro-tactile stimulation (VTS) to teach people skills, such as playing the piano, using touch-feedback training. The team decided to target spasticity, which VTS had helped in previousstudies of in-clinic (non-wearable) devices.

How does the device work? The researchers point to neuroplasticity, the ability of neurons to create new synapses or strengthen existing ones in the brain.

“The stimulation is sending additional sensory signals to the brain, which helps the brain interpret and reconnect any lost circuits,” Dr. Okamura said.

Spasticity is driven by “an imbalance in the excitatory drive to the muscles,” she continued. This can lead to worsening contractions, until a hand closes into a fist or a foot curls up. (The team has also done preliminary research on a similar device for foot spasticity, which they hope to continue developing.) Previous studies by Okamura and others suggest that vibration stimulation may prevent these contractions, both in the short and long term.

“Immediately, we do see some softening of the muscles,” Dr. Okamura said. “But in our longer-term study, where we compared to Botox, I also think that the vibration may be retraining the brain to send inhibitory signals. And that can restore balance that’s lost due to the damaged neural circuits from a stroke.”

When the team did a separate study comparing the effects of muscle and skin stimulation, they hypothesized that the vibration could be having a biomechanical effect on the muscle. Instead, they found that stimulating the skin had a greater impact — a “somewhat unexpected” result, Dr. Okamura said. That led them to the brain.

“Stimulating the skin is really about creating sensory signals that get sent to the brain,” Dr. Okamura said, “which is why we think it’s actually a brain-retraining effect and not a direct biomechanical effect.”
 

What’s Next?

The researchers are seeking funding for longer-term clinical studies to find out if effects persist beyond 2 weeks. They also want to explore how long and often patients should wear the glove for best results.

The researchers also want to study how movement might enhance the effects of the device.

“One of the treatments for spasticity — medications aside, this vibration machine aside — is more exercise, more passive range of motion,” said Oluwole O. Awosika, MD, associate professor at the University of Cincinnati College of Medicine, who was not involved in the study. “It would have been nice to have a control group that didn’t get any of this stimulation or that was only encouraged to do 3 hours of movement a day. What would the difference be?”

Dr. Awosika also wondered how easy it would be for stroke patients without in-home assistance to use the device. “Sometimes wearing these devices requires someone to put it on,” he said.

Of course, if all goes well, patients wouldn’t have to deal with that forever. “The dream would be that you reach true rehabilitation, which is no longer needing the device,” Dr. Okamura said.

The US Food and Drug Administration (FDA) has granted new approvals for the use of amivantamab-vmjw (Rybrevant, Janssen Biotech Inc.) in certain patients with locally advanced or metastatic non-small cell lung cancer (NSCLC). 

Specifically, the FDA approved the first-line use of the agent in combination with carboplatin and pemetrexed in patients with locally advanced or metastatic NSCLC with epidermal growth factor receptor (EGFR) exon 20 insertion mutations, as detected by an FDA-approved test. 

The FDA also granted traditional approval for use in these patients after their cancer has progressed on or following platinum-based chemotherapy. The original accelerated approval for this indication occurred in 2021. At that time, the FDA also approved Guardant360^® CDx (Guardant Health, Inc.) as a companion diagnostic test for amivantamab-vmjw. 

The first-line approval, which followed priority review, was based on the randomized, open-label PAPILLON trial, which revealed a statistically significant improvement in progression-free survival (PFS) among the 153 patients who received amivantamab-vmjw plus carboplatin and pemetrexed vs the 155 who received the chemotherapy combination alone. Median PFS was 11.4 months in the amivantamab-vmjw arm vs 6.7 months in the control arm (hazard ratio, 0.40).

Data for overall survival, a key secondary endpoint of the study, were immature at the time of the latest analysis, but “no trend toward a detriment was observed,” according to an FDA approval announcement.

Common adverse reactions, occurring in at least 20% of patients in the study, were rash, nail toxicity, stomatitis, infusion-related reaction, fatigue, edema, constipation, decreased appetite, nausea, diarrhea, and vomiting. Weight-based dosing guidance can be found in the full prescribing information.

TOPLINE:

Researchers have identified six blood biomarkers tied to changes in arterial inflammation in patients with rheumatoid arthritis (RA).

METHODOLOGY:

• Researchers selected 24 candidate blood biomarkers previously associated with both RA and systemic inflammation.
• They measured biomarkers in 109 patients in the , which tested whether different treatments for RA reduced arterial inflammation.
• Along with biomarkers, they measured arterial inflammation via [18F] fluorodeoxyglucose (FDG)-PET/CT scans at baseline and 24 weeks.

TAKEAWAY:

• Baseline levels of the biomarkers serum amyloid A, C-reactive protein, soluble tumor necrosis factor receptor 1, adiponectin, YKL-4, and osteoprotegerin were associated with significant changes in arterial inflammation on FDG-PET/CT scans.
• Adding these biomarkers to predictive models improved the adjusted R2 from 0.20 to 0.32 (likelihood ratio test, P = .0005).
• Researchers plan to validate these associations in a larger, external patient cohort.

IN PRACTICE:

This study is too preliminary to have practical applications.

SOURCE:

The study, led by Daniel Solomon, MD, of Brigham and Women’s Hospital, Boston, was published on February 28 in the Journal of the American Heart Association.

DISCLOSURES:

The research was funded by a National Institutes of Health grant as well as the Foundation for the National Institutes of Health Biomarkers Consortium. Several authors reported salary support or consulting fees from pharmaceutical companies.

The value of member community is highly prized at CHEST. In order to provide supportive and engaging spaces where members can convene, share resources, and learn from other members who share similar lived experiences and interests, we were proud to add Interest Groups to our member offerings in 2023.

The introduction of Interest Groups has proven to be an effective way to organically connect CHEST members with shared interests and passions. Membership in one of these groups allows for networking in a smaller setting, with the goals of supporting career development and enriching an individual’s professional path.

CHEST

CHEST

CHEST

1) Tell us about the key issues that your Interest Group is trying to address and who should join this group.

Mauricio Danckers: Our LGBTQ+ community continues to be the target of unrelenting discrimination. Current disparities toward sexual and gender-diverse individuals persistently hinder their personal and professional growth. There are several key issues currently affecting the LGBTQ+ community; among those are ongoing health care disparities, lack of education of our providers on LGBTQ+ health issues, underrepresentation of scientific research in the LGBTQ+ community, and scarce opportunities for mentorship and networking among LGBTQ+ health professionals. Our Interest Group seeks to provide a space to work together to overcome these shortcomings. Through the exchange of ideas, the opportunity for interprofessional collaborations, resource development and dissemination, scholar productivity, organic mentoring, and patient and provider advocacy, we seek to create change and better serve the LGBTQ+ identity in our CHEST community.          

Anyone who is ready to make a change for the LGBTQ+ community, their care, and their well-being is encouraged to join. Self-identification as a member of the LGBTQ+ community is not a prerequisite for joining our group. We welcome individuals committed to advancing gender-affirming health, wellness, and education approaches to reduce health disparities.

Kevin O’Neil: The Respiratory Care Interest Group is invested in a number of focus areas, including improving collaboration between pulmonary/critical care/sleep physicians and respiratory care providers with a goal of improved and more efficient patient care, addressing critical shortages in the respiratory therapist (RT) workforce in collaboration with respiratory care organizations by identifying and supporting strategies to grow the workforce, and promoting wellness in all members of the community by providing tools and resources to mitigate stress and reduce burnout.

This Interest Group is for any CHEST member with an interest in respiratory care education or care delivery.

Margaret Pisani: The Women in Chest Medicine Interest Group has two overarching goals. The first is focused on ensuring that content around sex as a biologic variable and the impact of gender—as they relate to lung disease and critical care—are addressed in the educational activities of CHEST. The second is to provide mentorship and aid with career advancement for women in pulmonary, critical care, and sleep medicine (PCCSM) who are members of CHEST.

Anyone who does research on the impact of sex and gender as biologic variables—and the importance of these variables in lung disease—is welcome in this Interest Group. Persons who would like to be involved in mentoring the next generation of women and junior members who would like to learn more about how to be active at CHEST are also encouraged to join.


2) What motivated you to lead an Interest Group?

Danckers: My path in medicine as an LGBTQ+ individual has been unique and personal. It has opened the opportunity to witness the urgency of the changes needed to serve our LGBTQ+ community better. I wanted to lead this Interest Group to connect to other members interested in advancing health care equity for LGBTQ+ individuals, to inspire one another to achieve major changes in LGBTQ+ health education, and to ignite an educational and social initiative supported by CHEST to witness the LGBTQ+ medical community thriving while grounded on mentoring and advocacy.

O’Neil: I’ve been a CHEST member for more than 35 years and involved with respiratory care almost as long. The relationship between pulmonary/critical care physicians and RTs is unique, and RTs are critically important to my ability to care for my patients. I am committed to facilitating opportunities for collaboration between the two groups.

Pisani: I am motivated by my passion to ensure we are providing the best possible education to our members and patients and supporting the next generation of leaders in the PCCSM community.



3) What are the goals for your Interest Group in 2024?

Danckers: 2024 will be an exciting year, no doubt about it! Our goals for 2024 are: 1) to connect talented individuals with professional goals that align with the ones from the Interest Group and CHEST, 2) to increase the presence of the LGBTQ+ identity representation in our CHEST scientific meetings and educational offerings, 3) to build a resource platform for LGBTQ+ health education with the innovative approach CHEST is known to provide, and 4) to provide venues to inspire and support scholarly work within the LGBTQ+ community.

O’Neil: Growing the Interest Group membership and increasing opportunities for RTs to participate in CHEST activities by providing a landing space for new RT members are key initiatives for us. We are also hoping to increase the visibility of the Interest Group through events at the annual meeting, educational offerings, and other opportunities as they arise. We will also focus on improving communication between CHEST and other respiratory organizations.

Pisani: We are focused on ensuring that sex and gender topics are addressed during scientific presentations when relevant to research and patient care and developing resources on specific topics where there is data regarding the impact of sex and gender in lung disease.

We welcome individuals committed to advancing gender-affirming health, wellness, and education approaches to reduce health disparities.

Kevin O’Neil: The Respiratory Care Interest Group is invested in a number of focus areas, including improving collaboration between pulmonary/critical care/sleep physicians and respiratory care providers with a goal of improved and more efficient patient care, addressing critical shortages in the respiratory therapist (RT) workforce in collaboration with respiratory care organizations by identifying and supporting strategies to grow the workforce, and promoting wellness in all members of the community by providing tools and resources to mitigate stress and reduce burnout.

This Interest Group is for any CHEST member with an interest in respiratory care education or care delivery.

Margaret Pisani: The Women in Chest Medicine Interest Group has two overarching goals. The first is focused on ensuring that content around sex as a biologic variable and the impact of gender—as they relate to lung disease and critical care—are addressed in the educational activities of CHEST. The second is to provide mentorship and aid with career advancement for women in pulmonary, critical care, and sleep medicine (PCCSM) who are members of CHEST.

Anyone who does research on the impact of sex and gender as biologic variables—and the importance of these variables in lung disease—is welcome in this Interest Group. Persons who would like to be involved in mentoring the next generation of women and junior members who would like to learn more about how to be active at CHEST are also encouraged to join.


2) What motivated you to lead an Interest Group?

Danckers: My path in medicine as an LGBTQ+ individual has been unique and personal. It has opened the opportunity to witness the urgency of the changes needed to serve our LGBTQ+ community better. I wanted to lead this Interest Group to connect to other members interested in advancing health care equity for LGBTQ+ individuals, to inspire one another to achieve major changes in LGBTQ+ health education, and to ignite an educational and social initiative supported by CHEST to witness the LGBTQ+ medical community thriving while grounded on mentoring and advocacy.

O’Neil: I’ve been a CHEST member for more than 35 years and involved with respiratory care almost as long. The relationship between pulmonary/critical care physicians and RTs is unique, and RTs are critically important to my ability to care for my patients. I am committed to facilitating opportunities for collaboration between the two groups.

Pisani: I am motivated by my passion to ensure we are providing the best possible education to our members and patients and supporting the next generation of leaders in the PCCSM community.



3) What are the goals for your Interest Group in 2024?

Danckers: 2024 will be an exciting year, no doubt about it! Our goals for 2024 are: 1) to connect talented individuals with professional goals that align with the ones from the Interest Group and CHEST, 2) to increase the presence of the LGBTQ+ identity representation in our CHEST scientific meetings and educational offerings, 3) to build a resource platform for LGBTQ+ health education with the innovative approach CHEST is known to provide, and 4) to provide venues to inspire and support scholarly work within the LGBTQ+ community.

O’Neil: Growing the Interest Group membership and increasing opportunities for RTs to participate in CHEST activities by providing a landing space for new RT members are key initiatives for us. We are also hoping to increase the visibility of the Interest Group through events at the annual meeting, educational offerings, and other opportunities as they arise. We will also focus on improving communication between CHEST and other respiratory organizations.

Pisani: We are focused on ensuring that sex and gender topics are addressed during scientific presentations when relevant to research and patient care and developing resources on specific topics where there is data regarding the impact of sex and gender in lung disease.

The value of member community is highly prized at CHEST. In order to provide supportive and engaging spaces where members can convene, share resources, and learn from other members who share similar lived experiences and interests, we were proud to add Interest Groups to our member offerings in 2023.

The introduction of Interest Groups has proven to be an effective way to organically connect CHEST members with shared interests and passions. Membership in one of these groups allows for networking in a smaller setting, with the goals of supporting career development and enriching an individual’s professional path.

1) Tell us about the key issues that your Interest Group is trying to address and who should join this group.

Mauricio Danckers: Our LGBTQ+ community continues to be the target of unrelenting discrimination. Current disparities toward sexual and gender-diverse individuals persistently hinder their personal and professional growth. There are several key issues currently affecting the LGBTQ+ community; among those are ongoing health care disparities, lack of education of our providers on LGBTQ+ health issues, underrepresentation of scientific research in the LGBTQ+ community, and scarce opportunities for mentorship and networking among LGBTQ+ health professionals. Our Interest Group seeks to provide a space to work together to overcome these shortcomings. Through the exchange of ideas, the opportunity for interprofessional collaborations, resource development and dissemination, scholar productivity, organic mentoring, and patient and provider advocacy, we seek to create change and better serve the LGBTQ+ identity in our CHEST community.
