Prehabilitation program reduces death risk for frail transplant candidates - News-Medical

Authorities in Abuja confirmed their first case of infection in an individual arriving from Uganda, which borders the worst-hit provinces in DRC. “The source of exposure is still not known and the travel history of the patient is being pieced together now in terms of her movement from Uganda up to Nigeria,” said Dr Patrick Otim, from the UN World Health Organization (WHO)’s Emergency Response programme, in an online update.

The same cause-and-effect approach is changing how researchers study brain disorders.. Last updated: October 23, 2026 | 09:167 MIN READThe major advance is that scientists can investigate what particular nerve cells actually do, rather than simply observe when they become activeIt started with a question about pond algae. Peter Hegemann wanted to know how Chlamydomonas, a green alga made of a single cell, steers itself towards light. In the early 2000s, he and Georg Nagel found the answer: Channelrhodopsin, a protein that opens a small gate in the cell when light strikes it. Karl Deisseroth, a psychiatrist and bioengineer at Stanford University, then took the leap. He put the gene for that protein into nerve cells, so that a flash of light could make them fire. By 2006 the method had a name: Optogenetics. On October 5, the three scientists were awarded the 2026 Nobel Prize in Physiology or Medicine for their discoveries concerning light-gated ion channels and optogenetics. Per Svenningsson, chair of the Nobel Committee, said the method allows mapping the brain 'in a way that we could once only dream of'. What does that actually mean for the rest of us?

Legalization of recreational cannabis in the US is associated with a rise in hospital admissions for cardiovascular disease, finds an analysis of more than 50 million patient discharge records, published in the open access journal BMJ Open. Admissions for atrial fibrillation (abnormal heart rhythm), heart failure, and heart attack all rose faster after the law was enacted in the Western region of the US with the policy than in states without, the analysis shows.

Investigators have developed and validated a clinical decision support tool to improve the diagnosis and treatment of chronic kidney disease (CKD) at the point of care. The research will be presented at ASN Kidney Week 2026 October 22–25. Called Treat CKD, the tool draws on electronic health records data to identify CKD, classify risk by Kidney Disease: Improving Global Outcomes criteria, calculate kidney failure risk using the Kidney Failure Risk Equation, estimate cardiovascular risk using American Heart Association PREVENT equations, and provide recommendations for albuminuria testing, blood pressure management, cholesterol-lowering therapy, cardio-kidney therapies, and nephrology referral.

Future pregnancy plans don’t preclude living kidney donation, but candidates should be counseled on gestational hypertension risk. Future pregnancy plans need not rule out living kidney donation, but candidates should be counseled on hypertensive risk. New data on pregnancy after living kidney donation give transplant teams clearer numbers to share with donor candidates who may want children in the future.¹In a matched cohort study from 3 Canadian provinces, presented at American Society of Nephrology (ASN) Kidney Week 2026 by Amit X. Garg, MD, PhD, and published simultaneously in JAMA, most donor pregnancies were uncomplicated, with a modest increase in hypertensive disorders of pregnancy.¹ Will Donating a Kidney Affect Future Pregnancies? In 2024, more than 40,000 living kidney donations were reported across 88 countries.¹ For donors who may become pregnant later, Garg said the central question is whether donation will affect those pregnancies.
