As more Americans with HIV live into older age, Medicare spending on their care is projected to rise dramatically from $10.9 billion in 2026 to $27.3 billion in 2035, with HIV medications accounting for nearly two-thirds of total costs. https://medicalxpress.com/news/2026-08-qa-medicare-clinical-people-aging.html Fri, 07 Aug 2026 13:00:05 EDT news705325321 Thanks to antiretroviral therapy and improved control of viral hepatitis (HBV and HCV), people living with HIV generally live longer and healthier lives. However, liver disease remains common in this population and is one of the leading causes of death. https://medicalxpress.com/news/2026-08-liver-disease-hiv-reveals-major.html Thu, 06 Aug 2026 10:20:02 EDT news705228002 A new UC San Francisco study helps explain why people with HIV remain at elevated risk for type 2 diabetes despite effective suppression of the virus with modern medications. https://medicalxpress.com/news/2026-08-adults-hiv-high-diabetes.html Thu, 06 Aug 2026 08:40:03 EDT news705215882 Hepatitis C remains a major cause of liver cirrhosis and liver cancer worldwide. Although highly effective antiviral medicines can cure most infections, many people remain undiagnosed or untreated because health care systems often fail to reach those at greatest risk. https://medicalxpress.com/news/2026-08-precision-screening-local-advance-hepatitis.html Wed, 05 Aug 2026 14:20:07 EDT news705156184 Around 78% of people living with HIV take a daily pill to manage their infection. These drugs work by preventing HIV from multiplying. https://medicalxpress.com/news/2026-08-onceweekly-hiv-pill-effective-daily.html Wed, 05 Aug 2026 12:40:07 EDT news705151622 A new biostatistical modeling approach has the potential to support health decisions by pinpointing where HIV is concentrated and where people living with HIV are showing signs of severe immune suppression or delayed treatment. Published in iScience, the study shows the potential of using existing health data to identify both where HIV burden is concentrated and where different forms of prevention, treatment and support may be needed. https://medicalxpress.com/news/2026-08-hiv-disease-advanced.html Wed, 05 Aug 2026 12:20:01 EDT news705148262 The tissue microenvironments surrounding HIV-infected immune cells look a lot like those surrounding cancerous tumors, reports a new Northwestern University study. https://medicalxpress.com/news/2026-08-tumor-tissue-environments-clues-hiv.html Wed, 05 Aug 2026 08:00:07 EDT news705129482 An immune pathway has been discovered that prevents a normally harmless fungus from developing into a fatal infection. The King's College London study, published in Nature Microbiology, provides the first potential clue as to why only certain patients with weakened immune systems, including those undergoing chemotherapy or living with HIV, are at risk of life-threatening Candida albicans infections. https://medicalxpress.com/news/2026-08-il-pathway-candida-fungus-fatal.html Wed, 05 Aug 2026 05:00:01 EDT news705055141 Special Rules for End of Life is an important mechanism in the benefits system designed to give people with a terminal illness fast-tracked access to vital financial support. But this qualitative study, the first to interview patients, caregivers and health care professionals about the issue, shows the system is failing too many dying people. Uncertainty about how long someone has left to live, low awareness of the rules, difficulties talking about money and practical barriers can all stop eligible people from getting the support they need. https://medicalxpress.com/news/2026-08-thousands-dying-people-vital-fast.html Tue, 04 Aug 2026 14:00:03 EDT news705056581 Mayo Clinic researchers have identified a protein that cancer cells use to shut down the body's immune response, a discovery that could help scientists develop new treatments that make cancer immunotherapies more effective. https://medicalxpress.com/news/2026-08-immune-cancer-cells.html Tue, 04 Aug 2026 13:40:07 EDT news705063781 If you're a Black, 34-year-old South African woman living with HIV, antiretroviral (ARV) treatment options have likely been limited to tenofovir disoproxil fumarate (TDF), lamivudine (3TC) and the "gold standard," dolutegravir (DTG). Now, another once-daily, three-drug regimen has been found to be as effective as DTG in suppressing HIV viral load. https://medicalxpress.com/news/2026-08-doravirine-dolutegravir-suppress-hiv-viral.html Mon, 03 Aug 2026 12:00:04 EDT news704977021 In a clinical trial of adults with HIV-related cryptococcal disease, those treated with a two-drug combination had a 21% lower risk of dying than those treated with just one drug. This is according to City St George's research presented July 31 at the International AIDS Conference 2026 in Brazil. https://medicalxpress.com/news/2026-08-death-patients-hiv-fungal-disease.html Mon, 03 Aug 2026 10:20:01 EDT news704965046 Scientists at the UC Davis School of Medicine have identified a naturally occurring metabolite that repairs gut damage caused by HIV infection and significantly improves the effectiveness of antiretroviral therapy (ART) in a nonhuman primate model of HIV/AIDS. https://medicalxpress.com/news/2026-07-probiotic-derived-bioactive-metabolite-reverses.html Thu, 30 Jul 2026 18:00:03 EDT news704646164 An international clinical trial led by researchers including Professor Chloe Orkin of Queen Mary University of London has shown that a once-weekly oral treatment for HIV is as effective as current leading daily therapies, offering the potential for a new treatment option that could reduce the burden of lifelong daily pill-taking. https://medicalxpress.com/news/2026-07-international-weekly-hiv-pill-daily.html Thu, 30 Jul 2026 10:40:10 EDT news704625722 Economic inequality is the clearest way to predict how countries will fare during a pandemic, a high-profile panel said Wednesday, calling for a rethink of how governments prepare for the next global health crisis. https://medicalxpress.com/news/2026-07-inequality-pandemic-outcomes-technical-readiness.html Thu, 30 Jul 2026 04:20:21 EDT news704603992 The U.S. government's withdrawal of funding for global HIV programs in January 2025 sharply reduced the number of people entering HIV care across East Africa within weeks, according to findings led by UC San Francisco researchers. https://medicalxpress.com/news/2026-07-hiv-funding-quickly-affected-east.html Tue, 28 Jul 2026 17:20:08 EDT news704476921 A new four-paper series in The Lancet Public Health reflects a two-year collaboration among researchers at San Diego State University and the Johns Hopkins Bloomberg School of Public Health, the Global Network of Sex Work Projects (NSWP), and sex workers from diverse geographic settings. Developed through meaningful community partnership, the collection provides the most comprehensive synthesis of evidence on sex workers' health in more than a decade and offers a contemporary approach to inform future research, policy and practice. https://medicalxpress.com/news/2026-07-paper-series-broadens-sex-workers.html Tue, 28 Jul 2026 07:20:05 EDT news704432761 The science has never been better, but political will has reached a new low: AIDS experts warned Monday that the fight against HIV was in real danger as funding fell by a fifth last year. https://medicalxpress.com/news/2026-07-hiv-real-danger-global-funding.html Tue, 28 Jul 2026 04:48:53 EDT news704432898 Three studies presented at the Society of NeuroInterventional Surgery's (SNIS) 23rd Annual Meeting found that racial, geographic and socioeconomic disparities continue to influence stroke treatment and outcomes across the United States. Together, the findings suggest that while advances in stroke care have improved survival and expanded treatment options, not all patients are benefiting equally. https://medicalxpress.com/news/2026-07-reveals-persistent-racial-disparities-treatment.html Thu, 23 Jul 2026 17:40:01 EDT news704019062 Drug-resistant Neisseria gonorrhoeae (the bacterium that causes gonorrhea) has become one of the most urgent antimicrobial-resistant threats to public health worldwide. Clinicians expect to be confronted by rising rates of treatment failure in the years to come. https://medicalxpress.com/news/2026-07-therapies-rapid-reshape-drug-resistant.html Thu, 23 Jul 2026 14:20:11 EDT news704030779 Dr. Alice Thornton has spent more than two decades treating people living with HIV in Lexington, Kentucky. Her team tends to "cringe" anytime they hear about patients having to fill out lots of paperwork, like when applying for Social Security Disability payments, because it can be a difficult, burdensome process. https://medicalxpress.com/news/2026-07-doctors-cringe-possibility-documenting-medicaid.html Tue, 21 Jul 2026 23:20:01 EDT news703856833 The Trump administration's disruptions to a global AIDS relief program have forced organizations to close clinics, lay off staff and cut services, seriously impeding efforts to prevent and treat the disease in dozens of countries, a new report released Tuesday shows. https://medicalxpress.com/news/2026-07-actions-global-efforts-hiv-dozens.html Tue, 21 Jul 2026 17:40:07 EDT news703868762 South Africa has the largest HIV epidemic in the world, with adolescent girls and young women ages 15–24 at the highest risk of getting HIV.

If their training data contains social biases, the models may unintentionally repeat those biases in their responses. As their use increases with the rise of generative AI, it has become evident that they contain biases that reinforce stereotypes based on factors like ethnicity, gender or geography. This is concerning because LLM-based chatbots have become an integral part of the health care system, where health-related stigma can negatively affect one's diagnosis and care. https://medicalxpress.com/news/2026-07-medical-ai-biased-paper.html Thu, 09 Jul 2026 08:20:05 EDT news702801724
