Researchers from the U.K. and U.S. analyzed blood samples from 200,618 U.K. Biobank participants, identifying 17 genes positively selected and driving clonal hematopoiesis. Clonal hematopoiesis involves the clonal expansion of mutated blood cells, with potential links to aging-related diseases. The study used exome sequencing to find genes under positive selection, including MTA2, SPRED2, and SRFS1,…
Researchers at the University of Michigan have created the first cellular map of a human ovary, a significant development in the quest to create a human artificial ovary for fertility restoration. This atlas of the ovary provides valuable insights into the molecular programs driving ovarian follicle development, shedding light on the biological mysteries of the…
A study conducted on nursing home residents found that the use of blood pressure drugs increases the risk of life-threatening bone fractures in the elderly. Nearly half of nursing home residents experience falls each year, with up to 25 percent leading to serious injury. The study compared the 30-day fracture risk in patients who started…
The CDC has launched an interactive map that shows influenza A virus levels in wastewater, including H5N1, to track potential spread. Wastewater surveillance cannot distinguish between virus subtypes or sources. H5N1 has been found in various bird and animal populations in the US. The dashboard is a new public health measure to track the spread…
A study published in Osteoporosis International explores the relationship between body mass index (BMI) trajectories in middle adulthood and the risk of bone fractures in late adulthood. The study, based on data from the Framingham Original Cohort Study, found that participants transitioning from overweight to normal weight during middle adulthood had a higher risk of…
A recent study in Scientific Reports examined Hypoactive Sexual Desire Disorder (HDSS) in women and men, a condition characterized by low sexual desire causing distress. Research using fMRI and questionnaires found women with HDSS exhibit hyperactivity in higher cognitive areas suppressing sexual brain regions, while men did not show this pattern. This study highlights sexual…
Roche announced that the FDA has approved their HPV self-testing kit. This kit is designed to screen for the human papillomavirus, which can help identify women at risk of developing cervical cancer earlier. This approval marks a significant step in improving early detection and potentially saving lives. Source link
The FDA cleared the expanded indication of the UltraClear cold ablative fractional 2,910 nm fiber laser for treating benign pigmented lesions and vascular dyschromia. Acclaro Medical, the company behind this laser, is focused on improving treatment for pigmentation disorders by offering a more effective alternative to acids, peels, and older devices. The UltraClear laser works…
The COVID-19 pandemic forced many older adults to adopt technology for social interactions, leading to changes in how they communicated within their support networks. A study by University of Washington researchers found that older adults not only received support through technology but also provided support, including emotional, financial, and physical assistance. The research emphasized the…
A study in Finland examined the costs of severe traffic injuries over a two-year period. The study found that the total costs were €20 million, with most costs being direct, followed by indirect and other costs. Patients with higher injury severity scores and injuries to the pelvis or lower extremities had higher total costs. The…
