1. GLP-1RAs may offer modest antidepressant effects compared to DPP4is but not SGLT-2is
Abstract: https://www.acpjournals.org/doi/10.7326/ANNALS-24-01347
URL goes live when the embargo lifts
A target trial emulation study compared risk for depression among older adults with type 2 diabetes initiating treatment with glucagon-like peptide-1 agonists (GLP-1RAs) versus sodium–glucose cotransporter-2 inhibitors (SGLT2is) or dipeptidyl peptidase-4 inhibitors (DPP4is). The data showed that risk for depression was low overall, with no difference in incidence when comparing GLP-1RAs to SGLT2is and a modestly reduced risk with GLP-1RAs compared to DPP4is. The findings are published in Annals of Internal Medicine.
Some research has suggested the potential of GLP-1RAs to alleviate depression symptoms due to its ability to cross the blood-brain barrier, however, population-based studies have yielded inconsistent results. Researchers from the University of Florida used U.S. national Medicare claims data between January 2013 and December 2020 to emulate a target trial assessing the risk of depression among older adults with diabetes initiating treatment with GLP-1RAs, SGLT2is or DPP4is. Participants were randomly assigned treatment to one of the three medications and were followed until the onset of depression, death, loss to follow-up, up to 2 years of follow-up, or the end of the study, whichever came first. There were 14,665 pairs of patients in the cohort for GLP-1RAs versus SGLT2is and 13,711 pairs in the cohort for GLP-1RAs versus DPP4is. Over the follow up period, 961 GLP-1RA users and 902 SGLT2i users were diagnosed with depression, indicating very little difference in risk for depression between GLP-1RAs and SGLT2is. In the cohort comparing GLP-1RA and DPP4is treatment, 963 and 1075 depression events occurred, respectively, suggesting an antidepressant effect of GLP-1RAs. More research is needed to confirm these findings; however, the findings could have important implications on the management of diabetes and depression in older adults.

2. No difference in prevalence of common chronic conditions between Medicare Advantage and fee-for-service populations
Abstract: https://www.acpjournals.org/doi/10.7326/ANNALS-24-01531
Editorial: https://www.acpjournals.org/doi/10.7326/ANNALS-25-00088

A nationally representative cross-sectional study aimed to determine the prevalence of chronic conditions among Medicare Advantage (MA) beneficiaries compared to those in fee-for-service (FFS) Medicare. The study found that prevalence of obesity, hypertension, hyperlipidemia and chronic kidney disease was not higher among MA compared to FFS beneficiaries, however, diabetes was more prevalent in MA beneficiaries. The findings suggest that excess payments to MA plans over the past 15 years may be driven more by diagnosis and coding practices rather than differences in disease burden by populations. The study is published in Annals of Internal Medicine.
Researchers from Beth Israel Deaconess Medical Center and colleagues studied data from 2,446 adults aged 65 and older obtained from the National Health and Nutrition Examination Survey (NHANES) between 2015 to 2018 and Medicare enrollment files. They sought to determine how biometric and lab markers of overall health (BMI, blood pressure, total cholesterol concentration, HgbA1c concentration, and eGFR) compare between MA and FFS beneficiaries and whether the prevalence of common chronic conditions (obesity, hypertension, hyperlipidemia, diabetes, and chronic kidney disease) is higher in MA beneficiaries. The researchers found that MA and FFS beneficiaries had very similar BMI, blood pressure, total cholesterol concentration, eGFR levels. MA beneficiaries had slighter higher average HgbA1c levels than FFS beneficiaries. According to the authors, this study provides a more accurate population-based estimate of health markers and chronic condition prevalence because it used direct physical examination and lab data, whereas prior work relied on administrative billing data and patient surveys.

Performance-Based Reimbursement Increases Administrative Burden and Moral Distress, Lowers Perceived Quality of Care
Background and Goal: Performance-based reimbursement (PBR) is a payment system in which clinics receive compensation based on the quality and outcomes of care they deliver, rather than the volume of services provided. Although designed to improve efficiency and effectiveness, the growth of PBR systems has been linked to increased administrative work for physicians. This study examined how PBR affects doctors' perceived ability to provide quality ...

Survey Finds Many Americans Greatly Overestimate Primary Care Spending
Background and Goal: This study, based on an online survey of 1,135 adults demographically representative of the U.S. population, aimed to measure public perceptions of primary care spending.
Key Insights: Respondents believed that 51.8% of overall health care spending goes to primary care—more than 10 times the documented share of 4.7%. Additionally, respondents believed that primary care addresses 58.7% of health care needs, very close to actual primary care utilization as a percentage of all ambulatory physician ...
Researchers advance RNA medical discovery decades ahead of schedule
2025-02-24
Ribonucleic acid, commonly known as RNA, is involved in many biological functions, and some, including gene silencing, are utilitized to cure diseases. RNA has recently gained attention as a promising drug target. Unfortunately, only a small fraction of RNA structures have been determined experimentally, and the process of uncovering these structures requires significant time and effort. Using this time scale, the structures of many life saving RNA may not be discovered for years. As a result, there is a significant gap between the types of known ...
Immune ‘fingerprints’ aid diagnosis of complex diseases in Stanford Medicine study
2025-02-24
Your immune system harbors a lifetime’s worth of information about threats it’s encountered — a biological Rolodex of baddies. Often the perpetrators are viruses and bacteria you’ve conquered; others are undercover agents like vaccines given to trigger protective immune responses or even red herrings in the form of healthy tissue caught in immunological crossfire.
Now researchers at Stanford Medicine have devised a way to mine this rich internal database to diagnose diseases as diverse as diabetes COVID-19 responses to influenza vaccines. Although they envision the approach as a way to screen for multiple diseases ...
Ancient beaches testify to long-ago ocean on Mars
2025-02-24
A Chinese rover that landed on Mars in 2021 detected evidence of underground beach deposits in an area thought to have once been the site of an ancient sea, providing further evidence that the planet long ago had a large ocean.
The now-inactive rover, called Zhurong, operated for a year, between May 2021 and May 2022. It traveled 1.9 kilometers (1.2 miles) roughly perpendicular to escarpments thought to be an ancient shoreline from a time — 4 billion years ago — when Mars had a thicker atmosphere and a warmer climate. Along its path, the rover used ground penetrating radar (GPR) to probe up to 80 meters (260 feet) beneath the surface. This ...
Gulf of Mars: Rover finds evidence of ‘vacation-style’ beaches on Mars
2025-02-24
UNIVERSITY PARK, Pa. — Mars may have once been home to sun-soaked, sandy beaches with gentle, lapping waves according to a new study published today (Feb. 24) in the Proceedings of the National Academy of Sciences (PNAS).
An international team of scientists, including Penn State researchers, used data from the Zhurong Mars rover to identify hidden layers of rock under the planet’s surface that strongly suggest the presence of an ancient northern ocean. The new research offers the clearest evidence yet that the planet ...

More than meets the eye: An adrenal gland tumor is more complex than previously thought
2025-02-24
Fukuoka, Japan - Kyushu University researchers have uncovered a surprising layer of complexity in aldosterone-producing adenomas (APAs)—adrenal gland tumors that drive high blood pressure. Using cutting-edge analysis techniques, they discovered that these tumors harbor at least four distinct cell types, including ones that produce cortisol, the body’s main stress hormone. Published in the week beginning 24 February in PNAS, their findings not only explain why some patients with APAs develop unexpected health issues, like weakened bones, but also pave the way toward new treatment strategies.

Origin and diversity of Hun Empire populations
2025-02-24
The Huns suddenly appeared in Europe in the 370s, establishing one of the most influential although short-lived empires in Europe. Scholars have long debated whether the Huns were descended from the Xiongnu. In fact, the Xiongnu Empire dissolved around 100 CE, leaving a 300-year gap before the Huns appeared in Europe. Can DNA lineages that bridge these three centuries be found?
To address this question, researchers analyzed the DNA of 370 individuals that lived in historical periods spanning around 800 years, from 2nd century BCE to 6th century CE, encompassing sites in the Mongolian steppe, Central Asia, and the Carpathian Basin of Central Europe. ...
New AI model measures how fast the brain ages

A new artificial intelligence model measures how fast a patient’s brain is aging and could be a powerful new tool for understanding, preventing and treating cognitive decline and dementia, according to USC researchers.
The first-of-its-kind tool can non-invasively track the pace of brain changes by analyzing magnetic resonance imaging (MRI) scans. Faster brain aging closely correlates with a higher risk of cognitive impairment, said Andrei Irimia, associate professor of gerontology, biomedical engineering, quantitative ...
