People who reach 110 and beyond appear to have unusually large numbers of rare immune cells capable of killing abnormal cells. These CD4 cytotoxic T cells became more common with age and often expanded into large groups of nearly identical cells, suggesting the immune system was repeatedly responding to persistent…

The FDA is seeking feedback on a potential way of regulating medical devices equipped with generative AI features, informed by the process of training human clinicians. Described as a “competency-based approach,” the process would evaluate AI-equipped devices in increasingly clinical scenarios, including potentially…
Of more than 1,300 AI medical devices cleared by the FDA, only three tested for patient-centered outcomes like death and morbidity, data show. AI integration into healthcare is rapidly progressing. Medical societies like the AMA have called for stricter regulations due to concerns about bias and transparency in…

Collaborative investment will improve access to cancer care by providing no-cost lodging and support for patients and families
Scientists have uncovered why two seemingly opposite ways of targeting the same brain receptor can both promote weight loss. In mice, activating the GIP receptor in the brainstem reduced appetite, while blocking it in the hypothalamus removed a kind of “brake” on fullness signals. The discovery helps explain why very…
Scientists have identified an immune response that may explain why statins cause muscle pain, weakness, and exercise intolerance in some people. The finding could eventually lead to treatments that protect muscles while preserving the drugs’ lifesaving cardiovascular benefits.
Blood cancers that eventually worsen may carry detectable genetic warning signs years before patients develop serious symptoms. The findings could lead to earlier intervention while also helping doctors distinguish true cancer from harmless age-related blood changes.
Нейробластома — это злокачественное новообразование, которое развивается из клеток-предшественников нервной системы — нейробластов. Данная опухоль преимущественно встречается у детей. До 90% всех случаев нейробластомы выявляются в возрасте до 5 лет. Однако нельзя исключить вероятность ее развития и у взрослых. По…
