A pharmacist-driven Veterans Health Administration (VHA) care program for veterans recovering from hospital visits for chronic obstructive pulmonary disease (COPD) is helping reduce symptom burden, a new retrospective cohort study finds. 

Of 286 patients with COPD who participated in the program and reported outcomes, 62.6% said their symptoms improved, 28.7% said they had no change, and 8.7% reported worsening symptoms, according to Edward Portillo, PharmD, and colleagues in Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation. Patients whose medications were changed by VHA pharmacists with prescribing authority were more likely to experience clinically meaningful improvement in symptoms compared to those without this medication change (66.3% vs. 46.6%, respectively, P < .001).

“If you had a debilitating lung disease that was affecting your ability to breathe all day, affected your ability to go to the grocery store, made it hard for you to see your grandkids, and all of a sudden you had this visit and a month to 2 months later reported feeling a heck of a lot better—that’s a really big deal,” Portillo said in an interview with Federal Practitioner. 

COPD, a progressive and irreversible lung disease that encompasses emphysema and chronic bronchitis, is the fifth-leading cause of death in the US according to the most recently available data. Research has suggested that many patients do not receive guidance-concordant care. 

“The prevalence of COPD among our veteran population is threefold greater than in the civilian population, and 1 in 4 veterans have a COPD diagnosis,” noted Portillo a pharmacist at the William S. Middleton Veterans Affairs (VA) Hospital and an associate professor at the University of Wisconsin, Madison School of Pharmacy.

In 2015, Portillo developed a program called COPD Coordinated Access to Reduce Exacerbations (COPD CARE). The program, now operating at 50 VA medical centers, allows pharmacists to optimize medication, order spirometry, assess symptoms, place referrals for pulmonary rehabilitation, and support inhaler adherence and tobacco cessation. The pharmacists work with other members of the patient care teams such as primary care physicians and nurses.

“It's integrated within the teams themselves that serve our veterans, which is very unique for a service like this,” Portillo said.

The program is especially beneficial for patients within their first 30 to 90 days posthospitalization when they may not normally be seen in the clinic, Portillo said.

“We use a national dashboard to identify patients who left the [emergency department] or hospital, and then we assess if they’d be appropriate candidates for the program,” he said. “Our goal is to see patients as fast as 30 days and as late as 90 days, but ideally within 30 to 60 days of discharge.”

An initial in-person visit of ≤ 30 minutes is followed by a 15-minute follow-up phone call in 30 days to see if interventions have been continued, he said. 

The study analyzed data from September 2020 to February 2024 from 28 VA medical centers that administer the COPD CARE program. All patients had an initial wellness visit within 90 days of hospitalization and 2 COPD Assessment Test (CAT) scores. Among 326 patients, the average age was 73.2 years; 95.7% were male; 77.9% were White, 15.6% were Black, and 2.1% had Hispanic ethnicity. 

At the time of the wellness visit, patients mean CAT score was 18.4. It improved to 15.2 by follow-up, with especially large improvements in limitations (2.5 to 2.0), tightness (1.7 to 1.2), cough (2.5 to 2.1), energy (2.9 to 2.5), phlegm (2.4 to 2.0), and sleep (1.9 to 1.5).

Pharmacists created 236 COPD action plans, changed 208 medications, provided 151 service referrals, identified 117 nonadherent patients, and identified 62 incorrect techniques. 

But only 1 intervention – medication change – was linked to clinically meaningful improvements in symptoms.

“This is not a disease that's easy to change symptomatically,” Portillo said. “My hope is that over time, and with multiple visits, those patients shift into a mode of ‘I am actually feeling much better now.’” 

Suzanne Bollmeier, PharmD, professor of Pharmacy Practice at the University of Health Sciences and Pharmacy in St. Louis, who is familiar with the study but did not take part in it, told Federal Practitioner that the results align with previous research.

Bollmeier mentioned several studies that link pharmacist interventions to better health outcomes, including inhalation technique and medication adherence.

“Pharmacists are well-positioned within the health care team to help care for patients with COPD,” she said. “Pharmacists can help with patient adherence, inhaler education, and reduction in disease risk but also identify drug-related problems and modify respiratory regimens to better optimize patient outcomes.”

Moving forward, she said, “it would be interesting to see what specific medication regimen changes were made in this present study that led to improvement in symptoms.”

The study was funded by the VA Office of Rural Health and the University of Wisconsin Institute for Clinical and Translational Research, which is supported by the National Center for Advancing Translational Sciences. The study authors and Bollmeier had no disclosures.

ORLANDO, Fla. — The Centers for Medicare & Medicaid Services (CMS) will not cover continuous positive airway pressure (CPAP) treatment for people who are nonadherent by 90 days. However, that requirement is too stringent, said researchers who found more than one third of adults who struggled with adherence initially still used the therapy 1 year later at levels associated with clinical benefit.

To test the requirement, investigators assessed 132,492 patients in the Kaiser Permanente Southern California system. The patients were issued CPAP devices to treat obstructive sleep apnea from 2015 to 2023. At 1 year, 36% who would have failed the CMS requirement were still using their CPAP.

The results counter CMS’ assumption that poor early CPAP use always leads to long-term abandonment, said Dennis Hwang, MD, co-chair of Sleep Medicine and medical director of the Sleep Disorders Center at Kaiser Permanente Southern California in Fontana, California.

"We should transition away from a one-size-fits-all definition of success," Hwang added at the American Thoracic Society (ATS) 2026 International Conference.

Background and Methodology

The 90-day adherence requirement does not only apply to Medicare or Medicaid recipients, Hwang said; many private insurers have adopted the same policy. In contrast, Kaiser Permanente Southern California does not restrict usage based on early adherence.

Hwang et al considered any Kaiser Permanente member with any CPAP usage during the 12 months after being issued a device an active user. They tracked mean nightly minutes of use and the percentage of nights with ≥ 2 and ≥ 4 hours of average use.

Overall, 49% would have met the CMS criteria and used the therapy ≥ 4 hours on average each night for 70% of nights during the first 90 days. Kaiser Permanente members aged ≥ 65 years were more compliant, with 54% meeting the CMS benchmarks. ATS guidelines recognize that even ≥ 2 hours of CPAP per night on average can confer some benefits.

The average age in the study was 55 years, and the mean apnea-hypopnea index was 32-33 events per hour, suggesting severe obstructive sleep apnea at baseline. The cohort was diverse, with 42% White, 35% Hispanic, 10% Black, 9% Asian, and 4% other race or ethnicity.

Key Findings

A total of 64,568 adults would have been CMS adherent at 90 days; investigators compared outcomes at 12 months with another 67,867 nonadherent adults.

There were some significant differences between groups. The mean age was 56.4 years vs 53.7 years in the adherent group vs the nonadherent group; men made up a greater proportion of the adherent group, 68.5% vs 62.6%; and the mean number of events per hour was 35 vs 30 (P < .001 for all).

Among the 90-day nonadherent group, about 21% met the 2-hour or greater adherence benchmark, and approximately 14% used CPAP an average of ≥ 4 hours.

“Still a substantial number of [non-CMS adherent] patients are using CPAP,” Hwang said.

Failure to meet CMS adherence was associated with younger age, female sex, non-White race or ethnicity, lower socioeconomic status, and lower severity of obstructive sleep apnea.

“There is also an equity dimension. Whites had better adherence rates during the first 90 days, so there is already a disparity here in terms of outcomes,” Hwang said. Policy changes could improve access to long-term therapy on a more equitable basis, he added. For example, a 2023 ATS policy statement calls for a more patient-centric approach and a focus on reducing inequities.

An Arbitrary Requirement

The 90-day requirement seems a little short, said session co-moderator Oren Cohen, MD, assistant professor in the Department of Medicine, Division of Pulmonary, Critical Care and Sleep Medicine at Icahn School of Medicine at Mount Sinai in New York City, when asked to comment. “It can take longer to get a patient back into the clinic and go through a lot of the trial and error that it takes to do a mask fitting and adjust the pressures.”

If a patient is using their CPAP device for fewer than 4 hours a night in the early period, it doesn’t mean things are failing, Cohen said. “It’s just that you’ve got to keep trying and pushing forward.”

Nonetheless, there are some long-term noncompliant patients, Cohen said. “I certainly don’t think that somebody who’s not using the device for years should continue to hold on to it. That resource can be reallocated to somebody who would get more benefit from it. But I think setting a 90-day and 4-hour rule seems arbitrary…and there should be more leeway there.”

The study was independently supported.

Hwang and Cohen reported having no relevant financial disclosures.

Hello. I’m Dr Maurie Markman, from City of Hope. I’d like to discuss a very interesting paper that appeared in Cancer, entitled, “Association of alcohol intake over the lifetime with colorectal adenoma and colorectal cancer risk in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial.”

This is an important paper. It is very clear, certainly to those in the public health community and cancer doctors, that there is an association with alcohol intake and the risk of cancer. However, in population-based surveys, there is a very large percentage of individuals who do not appear to see the risk of alcohol intake, particularly excessive alcohol intake, related to cancer, or an even larger segment of population simply doesn’t know. This analysis is important to help address this question.

The investigators looked at adults in the United States who were enrolled in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial, which is a very important study that had been ongoing for many years. Individuals in this study reported at several timepoints during their participation what their current and past alcohol intake was.

What these investigators found is as follows. Among the 88,092 participants, there were a total of 1679 incident colorectal cancers that developed over 20 years of follow-up. Investigators demonstrated that current drinkers with an average lifetime alcohol intake of 14 or more drinks per week, or approximately 2 drinks per day, had a higher risk of colorectal cancer with a hazard ratio of 1.25, a 25% increase, compared to those individuals who had ≤ 1 drink per week.

Very importantly, individuals were characterized by their own information that they provided as consistent heavy drinking versus light drinking. This was associated with almost a doubling of the risk of the development of colorectal cancer over that 20-year period.

Clearly, heavy drinking and higher lifetime alcohol intake is associated with an increased risk of colorectal cancer. This is relevant information for public health officials, primary care doctors, and the public in general to understand that there is a risk if you drink often, particularly heavy drinking, with increased development of cancer in general — but in this case, we’re talking specifically about colorectal cancer.

I thank you for your attention.

I’d like to discuss a very interesting paper that appeared in Cancer, entitled, “Association of alcohol intake over the lifetime with colorectal adenoma and colorectal cancer risk in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial.”

This is an important paper. It is very clear, certainly to those in the public health community and cancer doctors, that there is an association with alcohol intake and the risk of cancer. However, in population-based surveys, there is a very large percentage of individuals who do not appear to see the risk of alcohol intake, particularly excessive alcohol intake, related to cancer, or an even larger segment of population simply doesn’t know. This analysis is important to help address this question.

The investigators looked at adults in the United States who were enrolled in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial, which is a very important study that had been ongoing for many years. Individuals in this study reported at several timepoints during their participation what their current and past alcohol intake was.

What these investigators found is as follows. Among the 88,092 participants, there were a total of 1679 incident colorectal cancers that developed over 20 years of follow-up. Investigators demonstrated that current drinkers with an average lifetime alcohol intake of 14 or more drinks per week, or approximately 2 drinks per day, had a higher risk of colorectal cancer with a hazard ratio of 1.25, a 25% increase, compared to those individuals who had ≤ 1 drink per week.

Very importantly, individuals were characterized by their own information that they provided as consistent heavy drinking versus light drinking. This was associated with almost a doubling of the risk of the development of colorectal cancer over that 20-year period.

Clearly, heavy drinking and higher lifetime alcohol intake is associated with an increased risk of colorectal cancer. This is relevant information for public health officials, primary care doctors, and the public in general to understand that there is a risk if you drink often, particularly heavy drinking, with increased development of cancer in general — but in this case, we’re talking specifically about colorectal cancer.

I thank you for your attention.

Individuals with obesity without diabetes taking GLP-1 receptor agonists (RAs) may have a reduced risk for certain cancers, a new study suggests.

The target trial emulation of more than 160,000 patients found that individuals receiving the medications had a 41% lower risk for obesity-associated cancers (OACs), with an even more substantial 68% risk reduction among men.

“If confirmed in prospective studies, GLP-1 RAs may be associated with a broader clinical profile that extends beyond obesity management to include potential effects on cancer risk,” wrote lead author A.H.-C. Hsu, of Houston Methodist Neal Cancer Center, Houston, and colleagues in Annals of Oncology.

How Are GLP-1 RAs Linked to Reduced Cancer Risk?

According to the investigators, obesity is a recognized risk factor for 13 malignancies: breast, colorectal, endometrial, kidney, pancreatic, thyroid, ovarian, esophageal, gastric, liver, and gallbladder cancers, as well as multiple myeloma and meningioma. These conditions account for about 40% of cancers diagnosed in high-income countries, with incidence rising fastest among younger adults.

Preclinical work suggests GLP-1 receptor activation can suppress proliferation in cancer cells that express the receptor, although these mechanisms remain poorly understood. Observational clinical data have linked GLP-1 RAs to lower cancer risk, mainly in people with type 2 diabetes, but it has remained unclear whether the same association would hold among patients with obesity without diabetes.

How Was the New Study Designed?

The investigators first identified 229,467 adults with obesity without diabetes or a prior OAC in the TriNetX federated database. These patients were entered into a target trial emulation framework, which uses trial-like eligibility, treatment, and follow-up rules to approximate a randomized comparison from observational data.

The population was divided into two cohorts; the first comprised patients who filled at least two prescriptions for a GLP-1 RA and the second included patients who received only diet or exercise counseling. Groups were balanced using 1:1 propensity score matching, yielding 80,899 patients per group. The mean age was 47 years, and about 72% of the population were women.

The primary outcome was the cumulative incidence of OACs over 2 years. Further analyses characterized the same outcome based on sex, BMI, race, and the two most-used drugs, semaglutide and tirzepatide.

What Were the Key Findings?

GLP-1 RA use was associated with a 41% lower incidence of OACs overall (hazard ratio [HR], 0.59). The association held across most subgroups, with a more pronounced benefit among men (HR, 0.32) compared with women (HR, 0.65).

Taking tirzepatide (HR, 0.31) was also associated with a greater risk reduction than taking semaglutide (HR, 0.80); however, the investigators encouraged a cautious interpretation of these findings because the study was not designed for a head-to-head comparison between the agents.

In contrast with the above positive findings, no significant risk reduction was observed among Black patients (HR, 0.77; 95% CI, 0.58-1.03) vs a roughly 50% risk reduction among White patients (HR, 0.54; 95% CI, 0.47-0.62).

The reason for the lack of benefit among Black patients is unclear.

Among specific OACs, greatest risk reductions were reported for multiple myeloma (HR, 0.37), pancreatic cancer (HR, 0.40), endometrial cancer (HR, 0.42), and colorectal cancer (HR, 0.49).

No significant risk reductions were observed for breast cancer, ovarian cancer, or meningioma.

What Are the Clinical Implications?

The investigators emphasized that the study, being observational, is insufficient to confirm that GLP-1 RAs prevent cancer in this patient population. Still, the findings may be worth mentioning to patients considering GLP-1 RAs.

While using GLP-1 RAs specifically to lower cancer risk is “not ready for prime time yet,” the data may offer some reassurance for patients concerned about OACs who already have reason to be prescribed GLP-1 RAs, Michael D. Iglesia, MD, PhD, told Medscape Medical News.

Iglesia, who was not involved in the study, took a more cautious stance on the subgroup findings, first pointing out that women report higher rates of gastrointestinal side effects with GLP-1 RAs, so “the men in this study may have received more consistent GLP-1 RA exposure.”

Commenting on the negative findings among Black patients in the study, Iglesia, who is a medical oncologist at the UNC Lineberger Comprehensive Cancer Center pointed out that this subgroup comprised only 82 GLP-1 RA users and 106 people on diet or exercise.

“Issues related to structural inequality and access to care often affect this kind of study,” he said, adding that further work on social and structural factors is needed “before we posit any biological underpinnings for this observed difference.”

What Questions Remain?

Hsu and colleagues called for long-term prospective trials and postmarketing surveillance to track cancer outcomes among GLP-1 RA users, particularly younger patients.

Underlying mechanisms remain a key unknown, the investigators noted, as it remains unclear whether GLP-1 RAs lower cancer risk through weight loss, direct effects on cancer cells, or some combination thereof.

“Knowing the mechanism behind the association shown in this paper would be important for understanding which cancer types may be treated best with GLP-1 RAs,” Iglesia said.

The investigators and Iglesia reported having no conflicts of interest.

An investigational oral drug that targets RAS, the dominant oncogenic driver in pancreatic cancer, nearly doubled overall survival compared with common second-line chemotherapy regimens in patients with previously treated metastatic disease.

In the 500-patient phase 3 RASolute 302 trial, patients who received daraxonrasib, a RAS(ON) multi-selective inhibitor, lived a median of 13.2 months compared with 6.7 months for those who received chemotherapy. The drug also doubled progression-free survival, tripled the response rate, and delayed deterioration in both pain and quality of life.

“Results from RASolute 302 support daraxonrasib as a new standard of care for patients with previously treated metastatic pancreatic cancer,” said lead investigator Brian Wolpin, MD, MPH, director of the Hale Family Center for Pancreatic Cancer Research, Dana-Farber Cancer Institute in Boston, who presented the findings at the American Society of Clinical Oncology (ASCO) 2026. The study was also published simultaneously on May 31 in The New England Journal of Medicine.

Pancreatic ductal adenocarcinoma is one of the most lethal cancers, with most patients presenting with advanced disease at diagnosis. For those whose cancer progresses after first-line chemotherapy, no single standard second-line treatment has been established. Available regimens typically produce median progression-free survival of 3-4 months and a median overall survival of 6-7 months.

More than 90% of pancreatic cancers harbor activating RAS mutations — most commonly KRAS G12D and G12V — that drive tumor growth. The first approved KRAS inhibitors — sotorasib and adagrasib for certain lung and colorectal cancers — target KRAS G12C, which is rare in pancreatic cancer. So far, no RAS-targeted therapy has been approved for pancreatic cancer.

Daraxonrasib takes a broader approach. The oral agent can target a range of RAS variants, including mutant and wild-type RAS, by binding the active form of RAS and blocking downstream signaling.

In the phase 3 open-label RASolute 302 trial, researchers randomized 500 patients with previously treated metastatic pancreatic cancer 1:1 to receive daraxonrasib 300 mg orally once daily or investigator’s choice of chemotherapy. The most used regimens in the control arm were gemcitabine plus nab-paclitaxel (56.5%) and liposomal irinotecan plus fluorouracil and leucovorin (32.7%).

Patients were required to have an Eastern Cooperative Oncology Group performance status of 0 or 1. Documented RAS mutational status was required, and nearly 92% of patients had RAS G12 mutations.

The dual primary endpoints were overall survival and progression-free survival in the RAS G12 population. Key secondary endpoints included the same measures in the overall population as well as objective response rate and patient-reported quality of life. The median follow-up was 8.5 months.

In the RAS G12 population, daraxonrasib reduced the risk for death by 60% (hazard ratio [HR], 0.40; P < .001). The median overall survival was 13.2 months with daraxonrasib vs 6.6 months with chemotherapy. Results were nearly identical in the overall population: 13.2 vs 6.7 months (HR, 0.40; P < .001).

Progression-free survival in the RAS G12 population was 7.3 vs 3.5 months (HR, 0.45; P < .001). The objective response rate was 33.2% vs 11.8%.

Daraxonrasib significantly delayed deterioration in pain (median, 9.0 vs 3.7 months; HR, 0.51; P < .001) and global quality of life (5.6 vs 2.4 months; HR, 0.60; P < .001).

Treatment-related adverse events of grade ≥ 3 occurred in 43.6% of patients on daraxonrasib vs 57.5% of patients on chemotherapy. The most common high-grade events with daraxonrasib were rash (13.7%) and stomatitis (12.0%), whereas neutropenia (27.6%) and anemia (16.4%) were most common with chemotherapy.

One patient in the daraxonrasib arm died from treatment-related pneumonitis. Discontinuation due to adverse events occurred in 1.2% of patients on daraxonrasib vs 11.2% of patients on chemotherapy.

The median duration of treatment was 6.2 months with daraxonrasib vs 1.5-3.2 months across chemotherapy regimens, and 42% of patients on daraxonrasib remained on treatment at data cutoff, Wolpin said.

The open-label design is a limitation. About 15% of patients randomized to chemotherapy never received treatment, largely after learning their treatment assignment, although all were included in the intention-to-treat analysis.

Invited discussant Jennifer Knox, MD, a medical oncologist at Princess Margaret Cancer Center and professor of medicine at the University of Toronto in Toronto, Ontario, Canada, called daraxonrasib a game changer, describing the drug as “probably the most exciting strategy in five decades” for pancreatic cancer.

“It is an absolutely beautiful curve,” Knox said of the overall survival data, noting that the Kaplan-Meier curves separated early and continued to widen over time — a pattern rarely seen in pancreatic cancer trials where initial separation between treatment arms typically narrows as patients in both groups deteriorate.

Knox highlighted the pain and quality-of-life data as “the most important endpoints for our patients,” given the severity of the disease.

She pointed out, however, that the combination of rash and stomatitis will be “challenging” in practice, and called for improved supportive care and closer collaboration with dermatology as oncologists gain experience with this first-in-class drug.

Knox said RAS-targeted therapy “should dominate trials across the full spectrum of pancreatic cancer clinical presentations,” pointing to first-line combination trials already underway and noting that treating a larger, earlier population would have the greatest impact.

“This is the first glimpse at the real power of targeting RAS in pancreas cancer,” Knox said.

The study was funded by Revolution Medicines. Wolpin reported consulting or advisory roles with Revolution Medicines, Mirati Therapeutics, Ipsen, and others, and institutional research funding from Revolution Medicines, Agios, Amgen, AstraZeneca, Lilly, and Novartis. Knox reported receiving honoraria from Astellas Pharma, AstraZeneca, Incyte, and Ipsen, and consulting or advisory roles with AstraZeneca/MedImmune, Incyte, and Ipsen.

Progression-free survival in the RAS G12 population was 7.3 vs 3.5 months (HR, 0.45; P < .001). The objective response rate was 33.2% vs 11.8%.

Daraxonrasib significantly delayed deterioration in pain (median, 9.0 vs 3.7 months; HR, 0.51; P < .001) and global quality of life (5.6 vs 2.4 months; HR, 0.60; P < .001).

Treatment-related adverse events of grade ≥ 3 occurred in 43.6% of patients on daraxonrasib vs 57.5% of patients on chemotherapy. The most common high-grade events with daraxonrasib were rash (13.7%) and stomatitis (12.0%), whereas neutropenia (27.6%) and anemia (16.4%) were most common with chemotherapy.

One patient in the daraxonrasib arm died from treatment-related pneumonitis. Discontinuation due to adverse events occurred in 1.2% of patients on daraxonrasib vs 11.2% of patients on chemotherapy.

The median duration of treatment was 6.2 months with daraxonrasib vs 1.5-3.2 months across chemotherapy regimens, and 42% of patients on daraxonrasib remained on treatment at data cutoff, Wolpin said.

The open-label design is a limitation. About 15% of patients randomized to chemotherapy never received treatment, largely after learning their treatment assignment, although all were included in the intention-to-treat analysis.

Invited discussant Jennifer Knox, MD, a medical oncologist at Princess Margaret Cancer Center and professor of medicine at the University of Toronto in Toronto, Ontario, Canada, called daraxonrasib a game changer, describing the drug as “probably the most exciting strategy in five decades” for pancreatic cancer.

“It is an absolutely beautiful curve,” Knox said of the overall survival data, noting that the Kaplan-Meier curves separated early and continued to widen over time — a pattern rarely seen in pancreatic cancer trials where initial separation between treatment arms typically narrows as patients in both groups deteriorate.

Knox highlighted the pain and quality-of-life data as “the most important endpoints for our patients,” given the severity of the disease.

She pointed out, however, that the combination of rash and stomatitis will be “challenging” in practice, and called for improved supportive care and closer collaboration with dermatology as oncologists gain experience with this first-in-class drug.

Knox said RAS-targeted therapy “should dominate trials across the full spectrum of pancreatic cancer clinical presentations,” pointing to first-line combination trials already underway and noting that treating a larger, earlier population would have the greatest impact.

“This is the first glimpse at the real power of targeting RAS in pancreas cancer,” Knox said.

The study was funded by Revolution Medicines. Wolpin reported consulting or advisory roles with Revolution Medicines, Mirati Therapeutics, Ipsen, and others, and institutional research funding from Revolution Medicines, Agios, Amgen, AstraZeneca, Lilly, and Novartis.

A US Department of Veterans Affairs (VA) Office of Inspector General (OIG) report has found that many patients who scored high on a screening for alcohol use are not receiving recommended counseling interventions.

The OIG report evaluated Veterans Health Administration (VHA) primary care staff adherence to the screening requirements and intervention interventions during fiscal year 2024 (October 1, 2023, to September 30, 2024). VHA primary care clinicians used the Alcohol Use Disorders Identification Test – Consumption (AUDIT-C), which produces a score of 0 to 12, to screen almost 4 million patients.

Based on sex-specific thresholds, the report found 8% of men and 11% of women screened positive for unhealthy alcohol use (AUDIT-C score ≥ 4 for men and ≥ 3 for women). However, because VHA electronic health record prompts clinicians to provide intervention for patients with scores ≥ 5, 54% of men and 75% of women who may have benefited from brief intervention did not.

A brief intervention with a clinician consists of a 5-minute counseling session, with individualized feedback and a discussion on strategies for the patient to reduce or abstain from alcohol.

Aligning with VHA guidance, clinicians provided brief intervention to 77% of men and 75% of women who recorded an AUDIT-C score ≥ 5. However, < 2% of patients with a score at the sex-specific threshold received brief intervention.  

Veterans have high rates of unhealthy alcohol use, which is associated with increased risk of interpersonal violence and poor health outcomes. In a May 2026 study, 44% of 3117 veterans met criteria for alcohol use disorder; 44% reported past 30-day alcohol use.

The VHA requires annual screening using the AUDIT-C. In a study of 63,397 VHA patients, 25% of women and 28% of men screened positive for unhealthy alcohol use. The prevalence of alcohol and other substance abuse disorders increased with increasing AUDIT-C scores, ranging as high as 82% for women and 69% for men. 

A 2018 analysis found that tailoring the AUDIT-C binge-drinking item, AUDIT-C scoring, or both increased detection of unhealthy alcohol use in women. In 2020, VHA adjusted the binge drinking item for women, reducing it to 4 drinks on an occasion from 6 to characterize binge drinking. Despite this adjustment, the VHA maintained an AUDIT-C score ≥ 5 to prompt brief intervention for both women and men.

A 2022 study of 4148 veterans found that 15% were not properly screened for alcohol despite 1 in 11 met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for alcohol abuse/dependence. A lack of screening may not be the issue, however. In the OIG report, VHA found 95% adherence to alcohol use screening in 2024 using a sample-based performance measure and 79% adherence after transitioning that year to a population-based measure. OIG determined that the population-based measure provides a more accurate representation of screening documentation.

Following the OIG recommendations, VA Under Secretary for Health John J. Bartrum, JD, MBA, provided an action plan to evaluate factors that affect screening, identify facilities for performance improvement, and evaluate the use of sex-specific alcohol use screening thresholds.

TOPLINE: Serum P21 Activated Kinase 6 (PAK6) demonstrated diagnostic accuracy comparable to pro-gastrin-releasing peptide (ProGRP) for small cell lung cancer (SCLC), with area under the curve (AUC) values of 0.892 and 0.935, respectively, in a study of 109 patients with SCLC. Combining PAK6, ProGRP, and neuron-specific enolase (NSE) achieved diagnostic efficiency of 0.98. Elevated baseline PAK6 levels correlated with shorter progression-free survival and increased risk for disease progression.

METHODOLOGY:

• Participants included 380 people in China: 109 with SCLC, 92 with non–small cell lung cancer (NSCLC), 85 with benign pulmonary nodules, and 94 healthy controls who received routine physical examinations. 

• Laboratory testing measured serum PAK6 by ELISA, while NSE, carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and ProGRP were quantified by chemiluminescence. 

• Pretreatment and posttreatment serum samples from 56 patients with SCLC were analyzed to evaluate changes in biomarker levels following 3 months of treatment. 

• Progression-free survival data were collected through case review and follow-up, defined as time from treatment initiation to radiographic disease progression per RECIST 1.1 criteria or death from any cause.

TAKEAWAY:

• Median serum PAK6 is reported as 56.44 ng/L in SCLC vs 41.06 ng/L in NSCLC, 37.82 ng/L in pulmonary nodules, and 34.75 ng/L in healthy controls (P < .01). 

• PAK6 demonstrated diagnostic efficacy with and AUC of 0.892 (95% CI, 0.857-0.927), sensitivity of 0.82, and specificity of 0.86 at optimal cut-off value of 47.30 ng/L, comparable to ProGRP (AUC, 0.935) and superior to CEA (AUC, 0.676) and CA19-9 (AUC, 0.611). 

• In 56 paired SCLC samples, PAK6, NSE, and ProGRP decrease after 3 months of treatment (P < .001), while CEA and CA19-9 display no meaningful change. 

• Elevated baseline PAK6 expression correlated with shorter progression-free survival, with high-expression patients demonstrating median survival of 92 days vs 194 days in low-expression patients (HR, 2.02; 95% CI, 1.33-3.07; P = .001).

IN PRACTICE: “We identify PAK6 as a multi-faceted biomarker for SCLC with diagnostic, prognostic, and therapeutic monitoring value. Its cost-effective ELISA quantification facilitates clinical translation,” wrote the authors of the study. “Integrating PAK6 with emerging technologies could further refine SCLC management paradigms.”

SOURCE:The study was led by Simei Chen, Department of Blood Transfusion, the Second Affiliated Hospital, Jiangxi Medical College, Nanchang University in Nanchang, China. It was published online in PeerJ.

LIMITATIONS: A single-center design and modest sample size may limit generalizability of the diagnostic and prognostic estimates. The authors also note the absence of immunohistochemical validation, leaving tissue-level correlation of PAK6 unaddressed. Finally, insufficient overall survival data were reported, which constrains interpretation beyond PFS and supports the need for prospective follow-up and larger multi-center validation.

DISCLOSURES: Grant support came from the Science and Technology Program Project of Jiangxi Provincial Administration of Traditional Chinese Medicine (Grant 2024B1433). The authors stated the funders had no role in study design, data collection and analysis, the decision to publish, or manuscript preparation. No competing interests were disclosed.

Asthma biologics significantly improved lung function in children with asthma using race-based reference points, based on new data from 115 individuals.

Data on the effect of biologics on lung function in pediatric asthma are limited, and the main previous study of this relationship, the VOYAGE trial, was limited by its reliance on older, race-specific spirometry equations, according to Ken Wu, medical student at Indiana University School of Medicine in Indianapolis.

Newer, race-neutral reference equations prevent the systematic underestimation of asthma severity in Black patients and consequently provide a more accurate assessment of therapeutic benefits, said Wu. “Our study offers a novel contribution to the literature as the first known to utilize race-neutral equations to evaluate lung function following biologic therapy in a pediatric asthma population,” he said.

In a new study, presented at the American Thoracic Society (ATS) 2026 International Conference, the researchers conducted a real-world analysis with race-neutral reference equations developed by the Global Lung Function Initiative to assess the effect of biologics on lung function. They reviewed data from 115 pediatric patients with asthma who started biologics for the first time between 2015 and 2025. Their analysis included height, weight, forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratios. The mean age of the patients was 11.4 years, 52% were male, and 62% were Black. A majority (97 patients) received dupilumab; 13 received omalizumab, and 5 received mepolizumab.

The analysis included an average of three spirometry measures 1 year before starting biologics and an average of four measures during the year after starting biologics.

Treatment with dupilumab was associated with a significant improvement in lung function, with an increase in the average FEV₁ from 86.4 percent-predicted prior to biologics to 91.7 after biologics (mean difference, 5.31; P = .044). No significant differences appeared among omalizumab or mepolizumab patients, likely because of the small numbers, the researchers noted.

Overall, in a linear mixed model adjusting for biologic type, FEV₁ remained significantly higher after use of biologics than in the period prior to use (97.9 vs. 92.5), with a mean difference of 5.37 (P = .039).

The primary finding that dupilumab improved the percent-predicted FEV₁ by 5.31 is considered a modest effect size and mainly aligns with previous research, said Wu. “We are currently in the process of conducting additional analysis of whether there is a difference in lung function when we use the older race-specific equations versus our current findings with the newer race-neutral equations,” he said.

The findings were limited by several factors, including the relatively small study population and inclusion of only 3 types of biologics, with samples of omalizumab and mepolizumab that were underpowered to detect differences in lung function, said Wu. Additional studies with larger sample sizes, more biologics (including benralizumab and tezepelumab), and longer follow-up periods are needed to compare benefits across agents, he said.

Promising Implications for Practice

The ATS has recommended abandoning the previous race-adjusted pulmonary function test norms, said Timothy Joos, MD, who practices internal medicine and pediatrics at a community health center in Seattle.

These norms assigned smaller lung volumes to Black and Asian individuals and tended to underestimate lung disease in these populations, said Joos, who was not involved in the new study.

The current study, though small, showed with race-neutral reference equations that biologic agents significantly improved FEV1 values in children with severe asthma, said Joos. The association was especially strong with dupilumab, used by 85% of the patients, he noted. However, additional studies are needed with larger patient populations and other biologic agents to confirm the results, he said.

The study was supported by the Indiana Clinical and Translational Sciences Institute. The previous VOYAGE trial received funding from Sanofi and Regeneron Pharmaceuticals. The researchers reported having no financial conflicts to disclose. Joos reported having no financial conflicts to disclose.

The mean age of the patients was 11.4 years, 52% were male, and 62% were Black. A majority (97 patients) received dupilumab; 13 received omalizumab, and 5 received mepolizumab.

The analysis included an average of three spirometry measures 1 year before starting biologics and an average of four measures during the year after starting biologics.

Treatment with dupilumab was associated with a significant improvement in lung function, with an increase in the average FEV₁ from 86.4 percent-predicted prior to biologics to 91.7 after biologics (mean difference, 5.31; P = .044). No significant differences appeared among omalizumab or mepolizumab patients, likely because of the small numbers, the researchers noted.

Overall, in a linear mixed model adjusting for biologic type, FEV₁ remained significantly higher after use of biologics than in the period prior to use (97.9 vs. 92.5), with a mean difference of 5.37 (P = .039).

The primary finding that dupilumab improved the percent-predicted FEV₁ by 5.31 is considered a modest effect size and mainly aligns with previous research, said Wu. “We are currently in the process of conducting additional analysis of whether there is a difference in lung function when we use the older race-specific equations versus our current findings with the newer race-neutral equations,” he said.

The findings were limited by several factors, including the relatively small study population and inclusion of only 3 types of biologics, with samples of omalizumab and mepolizumab that were underpowered to detect differences in lung function, said Wu. Additional studies with larger sample sizes, more biologics (including benralizumab and tezepelumab), and longer follow-up periods are needed to compare benefits across agents, he said.

Promising Implications for Practice

The ATS has recommended abandoning the previous race-adjusted pulmonary function test norms, said Timothy Joos, MD, who practices internal medicine and pediatrics at a community health center in Seattle.

These norms assigned smaller lung volumes to Black and Asian individuals and tended to underestimate lung disease in these populations, said Joos, who was not involved in the new study.

The current study, though small, showed with race-neutral reference equations that biologic agents significantly improved FEV1 values in children with severe asthma, said Joos. The association was especially strong with dupilumab, used by 85% of the patients, he noted. However, additional studies are needed with larger patient populations and other biologic agents to confirm the results, he said.

The study was supported by the Indiana Clinical and Translational Sciences Institute. The previous VOYAGE trial received funding from Sanofi and Regeneron Pharmaceuticals. The researchers reported having no financial conflicts to disclose. Joos reported having no financial conflicts to disclose.
