Is Alzheimer’s Transmissible Through Bone Marrow Cells?
A mouse experiment suggested familial Alzheimer’s disease may be transmitted through bone marrow stem cells, but the implications of the findings were limited. The research involved transplanting bone marrow stem cells from mice engineered to carry a familial Alzheimer’s disease mutation into healthy mice, which led to “rapid development of Alzheimer’s disease pathological hallmarks,” reported […]
Low Rates of PSA Screening Linked to Increase in Metastatic Prostate Cancer
SAN ANTONIO — A study of men treated in Veterans Health Administration facilities suggested that lower prostate-specific antigen (PSA) screening rates were associated with subsequent increased rates of metastatic prostate cancer. Across 128 facilities, PSA screening rates declined from 47% in 2005 to 37% in 2019, which was observed across all ages and races, reported […]
Does the Mediterranean diet really decrease your risk of dementia?
A number of studies have suggested that eating a healthy diet may reduce a person’s risk of dementia, but a new study has found that two diets including the Mediterranean diet are not linked to a reduced risk of dementia. The study is published in the October 12, 2022, online issue of Neurology®, the medical […]
Benzodiazepines or Antihistamines for Acute Vertigo?
Moderately strong evidence suggested antihistamines provide greater acute vertigo relief than benzodiazepines, a meta-analysis showed. Single-dose antihistamines led to a 16.1-point (95% CI 7.2-25.0) greater decrease in vertigo symptom scores on a 100-point visual analog scale (VAS) compared with single-dose benzodiazepines at about 2 hours after treatment, reported Benton Hunter, MD, of Indiana University School […]
Maternal Health, Equity Key Factors in Proposed CMS Rule for Hospitals
In a new proposed payment rule for inpatient and long-term hospitals, CMS suggested the establishment of a “birthing-friendly” hospital designation in an effort to promote better health outcomes among mothers. In addition to addressing the nation’s maternal health crisis, the proposed rule includes three equity-focused measures as a way to improve care among underserved and […]
What Drives Post-COVID Cognitive Changes?
New research released today suggested that an over-stimulated immune system — possibly triggered by ongoing vascular injury and repair — may be behind persistent post-COVID cognitive changes. In preliminary work that will be presented at the American Academy of Neurology annual meeting, researchers led by Joanna Hellmuth, MD, MHS, of the University of California San […]
Large study challenges the theory that light alcohol consumption benefits heart health: Any observed benefit likely results from other lifestyle factors common among light to moderate drinkers, say researchers
Observational research has suggested that light alcohol consumption may provide heart-related health benefits, but in a large study published in JAMA Network Open, alcohol intake at all levels was linked with higher risks of cardiovascular disease. The findings, which are published by a team led by researchers at Massachusetts General Hospital (MGH) and the Broad […]
How Many People Have Cluster B Personality Disorders?
Studies have suggested that around 1%-6% of people suffer from cluster B personality disorders. Learn about each of the four types Studies have suggested that around 1%-6% of people suffer from cluster B personality disorders. According to the National Institute of Mental Health (NIMH), about 9.1% of the population in the United States have a […]
The sense of smell in older adults declines when it comes to meat, but not vanilla, researchers find
Contrary to what science once suggested, older people with a declining sense of smell do not have comprehensively dampened olfactory ability for odors in general — it simply depends upon the type of odor. Researchers at the University of Copenhagen reached this conclusion after examining a large group of older Danes’ and their intensity perception […]
