Despite popular beliefs, a recent Max Planck Institute study of 1,265 volunteers found no correlation between human sleep and lunar phases. The researchers discovered conflicting results may be due to publication bias, which can lead to omitted negative findings.
A systematic review of 8215 studies found that low-dose computed tomography (LDCT) screening does not significantly influence overall quality of life or result in long-term anxiety or distress. However, positive results can lead to short-term increases in distress levels.
Two studies published in PLOS Medicine found a link between moles and increased breast cancer risk. Women with more moles were more likely to develop breast cancer, particularly postmenopausal women. The findings suggest that nevi may be affected by hormone levels, which could be used as a marker for breast cancer risk.
Researchers found that even modest delays in TAVR can significantly impact its effectiveness in severely ill patients. Modest increases in wait times reduced the treatment's benefits, while prolonged waits made it less effective than surgery for high-risk surgical candidates.

The study used data from Taiwan's National Health Insurance program to track 1,377 people with obstructive sleep apnea and comp...
A prospective cohort study found that higher total folate intake was associated with a lower risk for exfoliation glaucoma (EG)/suspected exfoliation glaucoma (SEG). The results showed a trend of reduced EG/SEG risk with higher folate intake, particularly from supplements. This supports a possible causal role of homocysteine in EG/SEG.
Researchers found high-density lipoprotein (HDL) cholesterol and remnant lipoprotein (RLP) cholesterol levels are linked to CHD risk. HDL3 subfractions, not traditional HDL cholesterol, were more predictive in assessing and reducing CHD risk.
