Researchers using genetic data from nearly 2.8 million people identified new Alzheimer's disease risk loci and implicated microglial and neuronal pathways across diverse ancestral populations. Earlier estimates based on common variants may have underestimated the genetic contribution, with twin studies suggesting 60 to 80 percent of susceptibility is heritable. The findings may point to new therapeutic targets.

The FDA granted accelerated approval to Voceryq, the first recombinant plasmid DNA-based immunotherapy, for recurrent respiratory papillomatosis. The treatment aims to reduce the frequency of surgical excisions for wart-like growths caused by HPV in the airways. In clinical trials, 27 percent of patients with severe disease had a complete response, requiring no surgical excisions during 12 months of follow-up.

The TRANSFORM II trial found that drug-coated balloons were just as effective as standard drug-eluting stents for de novo coronary lesions, with a 12-month target lesion failure rate of 2.1 percent versus 2.4 percent. The study supports the use of drug-coated balloons as a safe and effective alternative to stents, avoiding the implantation of permanent metal in the artery.

However, rates of any target lesion revascularization were higher in the drug-coated balloon group.

The thalassemia drug mitapivat significantly improved hemoglobin response in patients with sickle cell disease but failed to reduce pain crises compared to placebo in a phase III trial. While 41 percent of patients on mitapivat had a hemoglobin response versus 3 percent on placebo, the annualized rate of pain crises did not differ significantly between groups.

The data are currently under FDA review for an expanded approval in sickle cell disease.

A Swedish registry study of nearly 1.5 million people found that children born to mothers with autoimmune disease during pregnancy had a 57 percent higher risk of type 1 diabetes, and paternal autoimmune disease showed a similar association. The risk was higher when a parent had type 1 diabetes. The authors said offspring of parents with autoimmune disease warrant monitoring.

Norwegian registry data found that adding spinal fusion to decompression surgery did not improve one-year disability in patients with spinal stenosis. Among 1,446 patients treated with decompression alone and 806 who also had fusion, Oswestry Disability Index scores were not significantly different after a year. Earlier trials also reported no disability benefit and more complications, longer operations and higher costs with fusion.

A Yakima County resident with previous health conditions died from bird flu complications after exposure to infected cattle at a dairy. This is the first US death from the virus in a year, with the CDC confirming the strain as H5N1. Officials reported 33 dairy herds recently tested positive, though the general public risk remains low.

A Chinese medical association group published 34 recommendations for surgical management of unilateral Wilms tumor, covering timing, biopsy, lymph node sampling, tumor thrombus, rupture and nephron-sparing surgery. It recommends immediate radical nephrectomy for resectable tumors and preoperative chemotherapy for selected high-risk or initially unresectable cases. It aims to reduce variation and prevent complications.

The National Comprehensive Cancer Network has published the first guidelines specifically for cancer caregivers, addressing medical management, emotional support, and financial issues. The guidelines aim to fill an information void as the number of cancer survivors and older patients increases, with at least 70% of caregivers having jobs and other responsibilities.

The resource includes a dedicated chapter on caregiver well-being and practical advice for navigating the healthcare system.

An analysis of a prospective cohort found that women using a combined GLP-1/GIP receptor agonist experienced improved menstrual regularity compared to those using GLP-1 drugs alone. The study reported a reduction in cycle length and variability, with more pronounced effects observed in patients with polyendocrine metabolic ovarian syndrome. The findings were presented at the American Society for Reproductive Medicine annual meeting.

A large Scandinavian clinical trial found that aspirin does not reduce the risk of cancer recurrence in patients who had surgery for colorectal cancer that had spread to the liver. The study, published in The Lancet Gastroenterology & Hepatology, involved 466 patients randomized at 14 hospitals in Norway, Sweden, and Denmark.

The results challenge previous observational studies that suggested aspirin might lower recurrence risk after colorectal cancer treatment.

Johns Hopkins researchers found that triptolide, a compound from thunder god vine, blocks DCTPP1, an enzyme cancer cells can use to break down DNA methyltransferase inhibitors before they work. In laboratory models, combining triptolide or related compounds with decitabine boosted reactivation of tumor suppressor genes and killed cancer cells. The findings suggest a way to overcome resistance to DNMT inhibitors.

UCSF has begun a first-in-human Phase I trial of repeated low-intensity focused ultrasound aimed at the caudate, a deep brain region, to reduce auditory hallucinations in schizophrenia. Up to 12 participants will receive five active sessions and five sham sessions, with brain imaging and symptom measures before and after treatment. The trial follows preliminary findings that a single session produced temporary reductions in hallucinations.

WHO chief Tedros Adhanom Ghebreyesus said recent Ebola and hantavirus outbreaks show the urgent need to complete an international pandemic treaty. He made the case at a Geneva negotiating meeting, where wealthy and developing nations remain at odds over the Pathogen Access and Benefit-Sharing system. The treaty, adopted in May 2025, would govern pathogen sharing and fair distribution of vaccines, tests and treatments.

A study from Oregon Health & Science University found that supplemental vitamin C during pregnancy can promote infant emotional well-being, particularly for mothers with high stress levels. The research, published in Developmental Psychology, indicates that adequate maternal vitamin C intake may reduce the risk of mental health disorders in offspring.

The findings suggest that vitamin C supplementation is a low-cost and accessible intervention to support healthy brain development.

A Newcastle hospital admitted that a seven month pregnant woman's unborn baby would have survived had she not been sent home from the Royal Victoria Infirmary. Danielle Brown was discharged with pre-eclampsia and told to book a slot to give birth after scans later revealed her daughter Maisie had died at about 29 weeks.

Global cervical cancer cases are expected to increase by 20.2% and deaths by 39.3% by 2050, according to a modeling study in Nature Medicine. The burden is projected to remain uneven, with sub-Saharan Africa facing the largest increases in both incidence and mortality. Researchers noted that no region is on track to meet the WHO elimination threshold of fewer than four cases per 100,000 people by 2050 if current trends continue.

The FDA gave tentative approval to Dr. Reddy's Laboratories to produce a generic version of lenacapavir, an HIV prevention injection. The company plans to begin shipping the drug next month, with an annual cost of $40 per person, to help expand access in low and middle income countries.

A study in Health Affairs found that Medicare spending increased by 5.9 percent per hospice stay after private equity firms acquired for-profit hospices. The rise was driven mainly by longer stays, with the average length of stay increasing by 6.3 days, rather than an increase in services. The findings suggest a shift toward patients who use less daily care, such as those with dementia, contributing to higher costs.

Researchers at Hanover Medical School and Renji Hospital treated seven patients with alpha-1 antitrypsin deficiency using CRISPR/Cas9 base editing. The team corrected the underlying genetic defect in liver cells, marking the first successful treatment for this congenital disorder. The findings were published in the Journal of Hepatology.

Researchers at UC Riverside and City of Hope identified a new strategy for treating systemic lupus erythematosus by targeting an imbalance in prolactin receptors. The study, published in Experimental and Molecular Medicine, found that using splice-modulating oligomers to prevent the production of the long-form prolactin receptor reduced inflammatory molecules and kidney damage in mouse models.

This approach preserves normal receptor function in healthy tissues like the brain and liver.

Health insurance premiums purchased through the ACA marketplace are expected to rise by 13 percent in 2027, driven by expiring financial assistance and rising healthcare costs. The sign-up window opened on November 1, with experts predicting fewer coverage options and higher prices for those who do not qualify for subsidies.

Roughly 19.2 million people are currently enrolled in ACA plans, with many facing increased costs as previous pandemic-era subsidies end.

A study presented at Kidney Week found that patients with stage 3 chronic kidney disease who received fruits and vegetables had better clinical outcomes than those treated with sodium bicarbonate or usual care. The research, involving 108 participants followed for 10 years, showed that the fruit and vegetable group had fewer hospitalizations, emergency department visits, and progression to kidney replacement therapy.

The findings highlight the potential quality-of-life and health-system value of dietary interventions.

A study led by the University of Maryland School of Medicine found that lowering doses of methadone or buprenorphine during pregnancy does not reduce the severity of neonatal opioid withdrawal syndrome. The research, published in JAMA Network Open, analyzed umbilical cord tissue from 92 pregnancies and found no association between medication levels and withdrawal severity.

The findings suggest that maintaining treatment is crucial for protecting mothers from relapse and overdose.

A study in The Lancet Psychiatry found that blood glucose levels surge rapidly within the first 90 days of starting second-generation antipsychotic therapy for schizophrenia. The research, which tracked 96,849 adults, showed that HbA1c increases jump roughly 14 times during this period, independent of weight gain. Clinicians are advised to monitor glycemic measures early, as the first three months represent a critical metabolic window.

A network meta-analysis of 95 trials found semaglutide produced the largest mean weight reduction among drugs for antipsychotic-treated patients with schizophrenia spectrum disorders. Liraglutide, topiramate, metformin and exenatide also showed significant weight loss versus placebo. The findings address metabolic side effects that can shorten life expectancy and reduce adherence.

Africa's latest Ebola outbreak has killed 5,376 people, with the vast majority of deaths occurring in the Democratic Republic of Congo. The epidemic, which began in May, has infected more than 10,000 people and spread to Kenya, Uganda and Nigeria. The outbreak is caused by the rare Bundibugyo virus, which currently has no approved vaccine or treatment.

African nations are seeking decision making power over how gene drive malaria tools are tested, governed and used as researchers move toward possible field trials. The World Health Organization estimates 282 million malaria cases and 610,000 deaths worldwide in 2024, with the African region carrying the greatest burden. Target Malaria hopes to conduct field trials by 2030 in a malaria endemic African country.

UC San Diego and UC Riverside researchers identified new antiviral targets for coronaviruses, including SARS-CoV-2, by mapping viral RNA-protein interactions. The Nature Communications study found that disrupting RNA binding sites for NSP8, NSP12 and nucleocapsid N reduced viral replication. Targeting essential viral machinery may help treatments resist rapid viral evolution.

A London School of Hygiene and Tropical Medicine study found surgery gave better three-year survival than stereotactic ablative radiotherapy for eligible early-stage non-small cell lung cancer patients. Using English data from 12,546 patients diagnosed 2015 to 2020, it estimated 21.6% of surgery patients died within three years, versus 30.3% after SABR. No clinically meaningful difference was found for people aged 80 and older.

A World Bank and Georgetown University study found that extreme heat can raise suicide risk through poor sleep quality and emotional dysregulation. The research, published Oct. 24, 2026, in Environmental Research, focused on climate-vulnerable settings such as Bangladesh. It says identifying temperature thresholds and pathways could help guide public health warnings and mental health support during heat events.

A multidisciplinary group has published a consensus providing 10 practical recommendations for diagnosing and treating lactose intolerance in newborns. The guidance emphasizes that symptoms in infants are often linked to digestive immaturity rather than inherited disorders. For breastfed infants, the strongest recommendation is to continue breastfeeding while adding lactase.

Pennsylvania's measles outbreak has put Lancaster county's Amish communities under the spotlight, with the state health department reporting 1,398 cases. Since 1 August, 150,000 MMR doses have been given, including more than 50,000 in October, as Governor Josh Shapiro mounts pop-up clinics and mailings. A study found less than a third of Amish residents had been immunized against measles, mumps and rubella.

Two studies involving Cedars-Sinai Guerin Children's and the University of Cambridge highlighted whole-genome sequencing for childhood cerebral palsy and cancer. One examined rapid whole-genome sequencing, with results in three to seven days, for children with cancer. The researchers said genomic medicine can help explain why a child develops a condition and, in some cases, change their care.

Baylor College of Medicine researchers found that reducing the protein Slingshot-1 improves Alzheimer's features in fruit fly models and human cells. The study focused on cytoskeletal remodeling, a network of protein fibers that supports cell structure and transport. The findings suggest a new pathway for slowing disease progression by enhancing the cell's natural recycling processes.

Researchers identified a new signaling pathway where gut immune cells sustain pain even after inflammation has resolved. The study found that tissue-resident macrophages use the Piezo1 channel to sense mechanical changes in inflamed tissue, triggering the production of nerve growth factor. Disrupting this process eliminated visceral pain sensitivity in mouse models of ulcerative colitis.

Researchers at St. Jude and Seattle Children's Hospitals found that genetic mutations present at diagnosis can predict relapse risk in B-cell acute lymphoblastic leukemia. The study, published in Blood, revealed that these risk factors vary by leukemia subtype, challenging the idea of universal resistance mutations. This finding may help tailor treatment intensity to prevent relapse.

Weill Cornell Medicine researchers found that many cancer cells are deficient in one of two redundant WNT-supporting enzymes, allowing a selective inhibitor to reduce WNT signaling with no apparent effect on healthy cells. The strategy was tested in early preclinical experiments and could benefit cancers with WNT hyperactivity, including colorectal and breast cancers. The study appeared in Nature Chemical Biology.

A study published in Nature Neuroscience shows that researchers can boost brain connectivity in mice without causing trip-like sensations by manipulating specific brain cell pathways. The findings suggest that psilocybin's neuroplasticity benefits, which increase dendritic spine volumes, can be isolated from its hallucinogenic effects, potentially leading to targeted treatments for depression and PTSD.

Researchers at Roswell Park Comprehensive Cancer Center identified a strategy to overcome resistance to KRAS targeted cancer therapies. The study found that blocking cell cycle regulators CDK4/6 or CDK2 restored sensitivity to these drugs in preclinical models, potentially improving treatment durability for patients with pancreatic and lung cancers.

Researchers launched an online portal providing free access to the Human BioMolecular Atlas Program, a comprehensive atlas of healthy human cells and tissues. The resource, built from data of more than 500 healthy donors, aims to help scientists and artificial intelligence efforts understand human health and disease by providing a healthy baseline for comparison.

An international team led by Northumbria University developed a five factor risk score to identify older people at elevated risk of dementia in low and middle income countries. The tool, which requires no blood tests or brain scans, was built to address the gap in prediction models designed for wealthier populations.

University of Pittsburgh and UPMC researchers found that pulmonary hypertension is linked to brain abnormalities driven by the same inflammatory processes and to cognitive issues such as impaired executive function and memory problems. The study, published in the Journal of Clinical Investigation, suggests cognitive decline may occur in other vascular and inflammatory conditions and points to a biological marker for screening.

A third participant received an intracortical visual prosthesis in a study at Rush University Medical Center aimed at restoring vision for people with total blindness. The wireless brain implant bypasses the retina and optic nerves to connect directly to the brain's visual cortex, marking a step toward scalable artificial sight.

More than two dozen hospital trusts that NHS England lists as realizing benefits from Palantir's medical data platform have said the system is not live or they are not using its applications. The gap between the NHS claim and the trusts' comments was described as very misleading by a senior health official, prompting calls to review the controversial £330m contract.

A study found that rates of electric bike and electric scooter injuries are rising in children and teens across the United States. E-bike injuries increased by 33 percent per quarter, and young people were more likely to be severely injured on these vehicles than on nonmotorized ones, prompting calls for age and speed limits.

Researchers at UC Berkeley, UCSF, and Stanford conducted parallel tests of psilocybin on mice and found no lasting behavioral changes 24 hours after a single dose. While acute effects like increased anxiety were replicable, the study found no evidence of reduced anxiety or depression-like behaviors, contrary to previous reports.

The findings highlight the importance of multi-lab collaborations to reduce publication bias and accurately estimate the drug's true effects.

A human challenge study found that excessive antibody driven viral growth in dengue infections can exhaust the immune system, leaving defenses active for only a short time. The research suggests that moderate viral replication coupled with early immune control provides the strongest and most durable immunity against the virus.

Three-parent IVF, a technique developed to reduce the risk of children inheriting sometimes-fatal mitochondrial diseases, is being marketed online as a fertility procedure for older women despite scant evidence it works. The procedure is illegal in the United States, but an Illinois-based company has connected women in the U.S. and Europe to clinics abroad.

An investigation found shoddy record keeping, incomplete data and a puzzling ancestry result.

France has ordered the withdrawal and recall of 15 types of ultra-thin condoms across the European Union after tests found manufacturing defects that could make them burst or rip. The products, made by Malaysian company Richter Rubber Technology, total about 7 million condoms and may reduce protection against STIs and unintended pregnancy. France suspended sales and imports for one year and advised users to seek STI or pregnancy testing.

The U.S. Food and Drug Administration issued final guidance for cellular and gene therapy makers to use a risk based potency assurance strategy. It replaces the 2011 potency testing guidance and applies to products for serious, often life threatening conditions. The guidance covers raw material controls, manufacturing tests and batch level lab tests, with notes for short shelf life, viral vector and patient specific therapies.

Research suggests that limiting access to sweets may cause children to overeat, as restriction can turn food into a moral judgment rather than fuel. Experts recommend managing candy inventories less strictly and encouraging autonomy to help children practice recognizing their own hunger and fullness cues. This approach aims to promote a healthier long-term relationship with food.

The Australian Health Data Evidence Network (AHDEN) has been established through a $9.5 million, three-year initiative to harmonize real-world data from hospital electronic medical records across the country. Led by Adelaide University and partnered with the Australian Research Data Commons, the network aims to improve data-driven healthcare while keeping patient information private and secure.

A systematic review and meta-analysis of 12 studies involving 4,268 patients found that mechanical thrombectomy was associated with lower 30-day, one-year and two-year mortality than anticoagulation alone in intermediate-risk pulmonary embolism. It was also associated with a lower risk of chronic thromboembolic pulmonary hypertension. A focused analysis found similar 30-day mortality, and larger randomized trials are needed.

A randomized trial at The Mount Sinai Hospital found that combining rotational atherectomy with intravascular lithotripsy before stent placement produced stent areas about 19 percent larger than lithotripsy alone in patients with calcified coronary nodules. The NODULE-SHOCK study, presented at the Transcatheter Cardiovascular Therapeutics conference, supports a more personalized approach for complex calcified lesions.

Researchers at Nanjing Medical University found that the protein ABCA1 plays a role in cholesterol accumulation linked to Parkinson's disease. The study, published in Nature Neuroscience, suggests that ABCA1 in astrocytes drives excessive cholesterol release, contributing to neuronal damage. This discovery identifies a new molecular target for developing treatments to slow disease progression.

Out-of-hospital cardiac arrest ICU admissions in the U.S. rose when daily temperatures exceeded 90 degrees Fahrenheit, especially in women and older adults. The preliminary study, to be presented at the American Heart Association's Resuscitation Science Symposium, found heat did not appear to change overall outcomes for patients admitted during heat waves. The findings matter as heat waves strain emergency services and hospitals.

New research analyzing data from nearly half a million U.S. adults found that cannabis use is associated with increased cardiovascular risk, particularly for stroke. The study notes that cannabis use has risen significantly in the United States, with one in six adults reporting use in the last month in 2024, making it an important consideration for heart disease prevention.

A study of 200 retired NFL players found that nearly 9 out of 10 had plaque in their coronary arteries, with 4 in 10 experiencing significant narrowing, yet almost none reported symptoms. The research, believed to be the first assessment of coronary plaque in retired professional football players, suggests a high risk of undiagnosed and untreated coronary artery disease.

Caffeinated energy drinks and stimulant supplements appeared disproportionately in FDA reports of serious cardiovascular events, including cardiac arrest and heart attacks, especially among adults aged 18 to 34. The research highlights that some energy drinks contain up to three times more caffeine per fluid ounce than brewed coffee, and pre-workout supplements can contain more than 12 times as much.

After nearly two decades of decline, death rates from valvular heart disease have increased from 2018 to 2023 and are predicted to remain elevated through 2040. The study found that while death rates improved for newer generations in their late 60s, those gains did not continue into very old age, with higher death rates at age 85 and older compared to earlier generations.

A study of over 250,000 adults with prediabetes and obesity found that GLP-1 medications may help prevent type 2 diabetes and lower the risk of heart attack and stroke more than metformin. The research, presented at the American Heart Association's Scientific Sessions 2026, suggests these drugs could be considered earlier for certain patients rather than waiting for a diabetes diagnosis.

A long-term study of more than 52,000 women in Israel found that contemporary hormone replacement therapy was not associated with an increased risk of heart attack, stroke, blood clots or death among women aged 45 to 59. The preliminary findings will be presented at the American Heart Association's Scientific Sessions 2026. The study adds to evidence that modern therapy may not raise risk for healthy women who start treatment around menopause.

Rural heart attack patients were nearly three times more likely to die before reaching hospital care than those in large metropolitan areas, preliminary research presented at the American Heart Association's Scientific Sessions 2026 found. The study also found a higher likelihood of out-of-hospital death among younger adults. Researchers said communities need reliable emergency medical services and timely access to heart attack care.

A study of nearly 1,000 older adults found that frequent nappers had a 48 percent higher rate of developing dementia over a median five-year follow-up period compared to those who rarely or never napped. The research suggests that frequent napping may be a marker of brain changes rather than a direct cause of cognitive decline. The findings were published in The Journals of Gerontology.

A new National Paediatric Early Warning System is being introduced in hospital emergency departments in England to help NHS staff identify sick children who are dangerously deteriorating. Staff will check, log and grade vital signs such as blood pressure, heart rate and oxygen levels, with a high score prompting more urgent attention. The system is intended to save lives ahead of winter, when NHS pressure is highest.

A recent review in the Proceedings of the Nutrition Society examined how food liking and wanting influence eating behaviour and responses to dietary or weight-management interventions. Liking is pleasure from food, while wanting is the motivation to obtain or consume it. The review notes these processes can change differently across people, foods and nutritional states, and may shape food choices and treatment outcomes.

A 2021 review in the Proceedings of the Nutrition Society examined how dietary fibre complexity influences the human gut microbiota. Differences in carbohydrate structure affect which bacteria break down fibre and how other microbes use the resulting nutrients. These microbes produce short-chain fatty acids, including acetate, propionate and butyrate, which can influence host energy metabolism and inflammatory processes.
