A study on chronic obstructive pulmonary disease (COPD) found that 44% of patients were under-treated, while only 19% received recommended medication regimens. Patients who were under-treated had fewer exacerbations, indicating that ignoring guidelines may be beneficial in certain cases.
Researchers use genetic correlation to link disease risks, including heart health and diabetes, using data from a long-standing cohort and electronic health records. The method provides opportunities to answer epidemiological questions in weeks rather than decades.
A recent study published in Nature Communications suggests that humans, not climate change, led to the extinction of Australian megafauna around 45,000 years ago. The researchers analyzed ancient poop and sediment cores, finding a significant decline in megafaunal populations during this period.
A UMass Amherst researcher argues that a historical investigation error led to the adoption of the LNT model, which challenged fundamental beliefs about ionizing radiation effects. The corrected research supports a threshold rather than linear dose response for carcinogens.
Researchers at Joslin Diabetes Center found that mice with reduced brain cholesterol suffer neurological damage and behavioral abnormalities. The study suggests that cholesterol may play a role in the development of Alzheimer's disease in people with diabetes.
