Young people living with HIV manage their condition better when their antiretroviral therapy is given by injections every eight weeks rather than daily tablets, according to results of a trial in Africa led by UCL (University College London) researchers. https://medicalxpress.com/news/2026-09-hiv-tablets-young-people-clinical.html Thu, 17 Sep 2026 18:30:01 EDT news708781562 Better cardiovascular health (CVH) is nonlinearly and inversely associated with overactive bladder (OAB), according to a study published in the August issue of the Annals of Medicine & Surgery. https://medicalxpress.com/news/2026-09-cardiovascular-health-inversely-linked-overactive.html Thu, 17 Sep 2026 17:40:09 EDT news708868188 Gut instinct, gut feeling or gutting it out—what exactly is the human gut? It's the workhorse of the digestive system and home to a vast, dynamic community of microorganisms that influence human health. In fact, the human body contains roughly equal numbers of nonhuman (microbial) and human cells. https://medicalxpress.com/news/2026-09-gut-complex-architecture-recreated-microscope.html Thu, 17 Sep 2026 17:40:01 EDT news708883861 Our hands may do more than complement what we say. They can also help our brains process grammar. In a new neuroimaging study published in PNAS, researchers from the Max Planck Institute for Psycholinguistics (MPI) in Nijmegen show that gestures can make it easier to process negative sentences ("I did not sleep"), providing the first neurocognitive evidence that gestures influence grammatical processing. https://medicalxpress.com/news/2026-09-gestures-brains-grammar.html Thu, 17 Sep 2026 17:20:06 EDT news708882301 Researchers from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have developed a new, noninvasive way to examine how blood flow and cellular organization align across the layers of the living human brain. https://medicalxpress.com/news/2026-09-mri-reveals-blood-brain-cells.html Thu, 17 Sep 2026 17:00:05 EDT news708868067 Autism spectrum disorder (ASD) is associated with more than 1,200 risk genes, raising a fundamental question: Do these diverse genetic changes affect the brain in entirely different ways, or do they converge on shared biological mechanisms? https://medicalxpress.com/news/2026-09-autism-mutations-reveal-opposing-patterns.html Thu, 17 Sep 2026 16:20:07 EDT news708879661 The American Association for Cancer Research has released its annual Cancer Progress Report, highlighting recent progress in cancer research. https://medicalxpress.com/news/2026-09-annual-highlights-cancer.html Thu, 17 Sep 2026 16:20:05 EDT news708868192 Deep in the brainstem sits a small but important cluster of neurons known as the locus coeruleus (LC), Latin for "blue place." It makes up a tiny fraction of the brain's cells but plays an important role by releasing the chemical messenger norepinephrine (NE). NE activates the body's response to stress or excitement, affects attention and learning, and affects heart rate. https://medicalxpress.com/news/2026-09-scientists-brain-mysterious-blue-longest.html Thu, 17 Sep 2026 16:00:27 EDT news708877321 With climate change leading to more extreme and prolonged heavy rainfall across the northern hemisphere, flooding is a risk, especially in fall and winter. https://medicalxpress.com/news/2026-09-biggest-death.html Thu, 17 Sep 2026 16:00:24 EDT news708879182 Infants born to mothers with depressive symptoms immediately after delivery had a substantially higher risk of dying before their first birthday, according to researchers involved in a Rutgers-led study of more than 414,000 births in New Jersey. https://medicalxpress.com/news/2026-09-maternal-postpartum-depressive-symptoms-linked.html Thu, 17 Sep 2026 15:40:13 EDT news708871314 Medicine should never feel out of reach. Yet for many Filipinos, a trip to the pharmacy can mean literally crossing mountains and streams for a handful of tablets. In a remote location in Barangay Kalawakan, Bulacan, getting to the nearest pharmacy can mean traveling almost a dozen kilometers without public transportation. A single trip to town can cost more than ₱400—almost an entire day's minimum wage. For some, the only alternative is more than an hour's walk, even in good weather. https://medicalxpress.com/news/2026-09-sari-bridge-medicine-gaps-remote.html Thu, 17 Sep 2026 15:40:09 EDT news708877681 Researchers are warning that inconsistent use of the terms "neurodiversity" and "neurodivergence" in mental health research could obscure important differences between diagnoses and make findings harder to interpret. They also say using the terms without further specification could encourage "one-size-fits-all" approaches in clinics, schools and workplaces that can overlook individual care and support needs. https://medicalxpress.com/news/2026-09-inconsistent-neurodivergence-language-complicate-patient.html Thu, 17 Sep 2026 15:20:01 EDT news708868634 The eyes are more than lenses to the outside world; they can also be windows that offer a glimpse into what's happening inside our bodies. What if the eyes could help us understand how attention shifts from one moment to the next? Scientists are now testing whether tiny changes in pupil size can serve as a physiological marker of these fluctuations in children with attention-deficit/hyperactivity disorder (ADHD). https://medicalxpress.com/news/2026-09-children-pupils-reveal-shifting-attention.html Thu, 17 Sep 2026 15:10:01 EDT news708875735 There is no cure for HIV. While scientists have made considerable progress in controlling the infection, patients still must take daily antiretroviral medication for the rest of their lives. Results from a clinical trial led by Rockefeller, Imperial College London, and the University of Oxford (RIO) have offered a new strategy, suggesting that just one or two doses of broadly neutralizing antibodies (bNAbs) can suppress the virus long term, keeping it at undetectable levels for months and even years. https://medicalxpress.com/news/2026-09-immune-hiv.html Thu, 17 Sep 2026 15:00:08 EDT news708871262 A new clinical trial led by researchers at the Institute of Psychiatry, Psychology & Neuroscience has found that exercise has a significant effect on mood and lab-based measures of new brain cell formation in healthy middle-aged participants. https://medicalxpress.com/news/2026-09-clinical-physical-trial-mood-neuron.html Thu, 17 Sep 2026 14:40:03 EDT news708870541 One person died from malaria in Frankfurt and another was infected, local health officials said Thursday, the latest cases in a malaria outbreak linked to the city's airport. https://medicalxpress.com/news/2026-09-malaria-death-germany-outbreak-frankfurt.html Thu, 17 Sep 2026 14:40:01 EDT news708869043 A new study published in the journal npj Breast Cancer demonstrates that an artificial intelligence (AI) model offers more accurate predictions of recurrence risk in patients with early-stage breast cancer than the widely used 21-gene Recurrence Score. This research, conducted by a team from the ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) and Caris Life Sciences, specifically targets hormone receptor-positive (HR+) and HER2-negative disease, the most common subtype of breast cancer, which accounts for about half of all breast cancer cases in the United States. https://medicalxpress.com/news/2026-09-ai-powered-accurate-breast-cancer.html Thu, 17 Sep 2026 14:20:10 EDT news708870361 People with a severe mental illness die more than 10 years earlier than the general population, research led by The University of Queensland has found. https://medicalxpress.com/news/2026-09-people-mental-illness-die-younger.html Thu, 17 Sep 2026 14:20:07 EDT news708867844 Fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) are the clinical gold standards for screening blood sugar levels, yet they provide only static snapshots that fail to reflect the highly dynamic and heterogeneous nature of metabolic impairment. However, continuous glucose monitoring (CGM) is reshaping our understanding of these levels. While the medical community already has begun capitalizing on CGM for diabetes management, a new study has the potential to change current clinical practices for cardiovascular disease risk stratification in individuals without diabetes. https://medicalxpress.com/news/2026-09-glucose-reveal-hidden-heart-patterns.html Thu, 17 Sep 2026 14:00:37 EDT news708863041 A rare inherited mutation in the Epidermal Growth Factor Receptor (EGFR) gene is associated with a 25-fold increased risk of lung cancer, according to a study by investigators at Dana-Farber Cancer Institute and 23andMe Research Institute. The findings included de-identified, aggregated genetic data from more than 3.3 million 23andMe research-consented participants. https://medicalxpress.com/news/2026-09-rare-inherited-egfr-mutation-linked.html Thu, 17 Sep 2026 14:00:29 EDT news708863161 Blood test trends alongside unexplained weight loss can improve triage for cancer testing, according to a study by Brian Nicholson and colleagues from the University of Oxford, UK, published Sept. 17 in the journal PLOS Medicine. https://medicalxpress.com/news/2026-09-blood-trends-patients-cancer.html Thu, 17 Sep 2026 14:00:21 EDT news708797521 Greater amounts of REM and deep sleep were associated with lower risks of dozens of diseases, and less than 5 hours of total sleep was associated with high disease risks, according to a new study published Sept. 17 in the journal PLOS Medicine by Shengzhi Sun of Capital Medical University, China, and colleagues. https://medicalxpress.com/news/2026-09-rem-deep-total-disease.html Thu, 17 Sep 2026 14:00:13 EDT news708797641 When a child needs emergency care, it makes sense to take them to the closest emergency department (ED)—but that may not be the medical facility best equipped to treat them. According to new research from the University of Missouri School of Medicine, access to pediatric-ready EDs may depend on the child's community and its access to resources. https://medicalxpress.com/news/2026-09-children-income-areas-er.html Thu, 17 Sep 2026 14:00:04 EDT news708867124 One of the biggest challenges in cancer immunotherapy may not be that immune cells are too weak, but that some tumors give them too little to see. New research from Dana-Farber Cancer Institute scientists reveals how cancers carrying mutations in the p53 tumor-suppressor protein can hide those mutations from T cells and suggests a therapeutic countermeasure: Change what the cancer displays on its surface so the immune system can recognize the tumor. https://medicalxpress.com/news/2026-09-invisible-cancers-visible-route-cold.html Thu, 17 Sep 2026 13:40:17 EDT news708870061 Most research on the diagnosis of dementia focuses on people who are never diagnosed. But in a new study, Yale researchers look at the other side: people who have been diagnosed but do not know it or do not acknowledge it. https://medicalxpress.com/news/2026-09-dementia-patients-dont-diagnosis.html Thu, 17 Sep 2026 13:40:15 EDT news708866762 Researchers have completed the largest study to date of TCF7L2-related neurodevelopmental disorder (TRND), a rare genetic condition caused by changes in the TCF7L2 gene, which plays an important role in brain development. By analyzing 76 patients from around the world in collaboration with sites across 14 countries and several U.S. cities, including Philadelphia and Boston, the team found that the most common identifying features were speech delay, autism, developmental delays, vision problems such as nearsightedness, and orthopedic issues affecting the muscles and skeleton. https://medicalxpress.com/news/2026-09-rare-newly-tcf7l2-neurodevelopmental-disorder.html Thu, 17 Sep 2026 13:20:12 EDT news708866402 Researchers at the University of Konstanz have demonstrated at a molecular level how bacteria in the human gut influence the entire body. Among other things, they can lower blood sugar levels and reduce fatty liver disease. The work is published in the journal EMBO Molecular Medicine. https://medicalxpress.com/news/2026-09-gut-microbe-molecule-reveals-molecular.html Thu, 17 Sep 2026 13:00:08 EDT news708865681 For as long as Laura Hogan, 69, can remember, living with the rare skin condition lamellar ichthyosis has meant more than managing painful blisters and scaly skin. Throughout her life, she also has dealt with food allergies, chronic bronchitis, countless eyelid surgeries and overheating in the summer. https://medicalxpress.com/news/2026-09-people-rare-skin-disorder-high.html Thu, 17 Sep 2026 13:00:01 EDT news708866102 Dizziness, fatigue, brain fog and a racing heart. They're commonly associated with long COVID, but new Adelaide University research suggests that for some people, these symptoms may also be indications of postural orthostatic tachycardia syndrome (POTS), a debilitating and difficult-to-diagnose condition. https://medicalxpress.com/news/2026-09-heart-reveal-overlap-covid-pots.html Thu, 17 Sep 2026 12:40:25 EDT news708865621 Many people will learn CPR using a flat-chested manikin. A 2024 study of 20 models of CPR manikins sold worldwide found that three-quarters were described as male or had no sex specified. Of the 20, only one offered a breast overlay. https://medicalxpress.com/news/2026-09-decades-malefocused-medical-bias-health.html Thu, 17 Sep 2026 12:40:03 EDT news708867062
