“Total LDL particles decreased by 4.3 percent, and small LDL particle number decreased by 6.1 percent. Interestingly, the LDL-lowering effects of the walnut diet differed by sex, with a 7.9 percent decrease in LDL among men and a 2.6 percent decrease among women.”

“The investigators collected blood from 15 participants with a lean BMI (less than 25) and 15 participants with an obese BMI (greater than 30) who tested positive for SARS-CoV-2. The investigators also collected blood from 30 participants who had not had a SARS-CoV-2 infection and were matched for age, sex, and BMI.”

“The authors recruited 43 participants who had Alzheimer's disease and 43 healthy participants who were matched with age and sex.

“The non-human primates performed a similar breath test as the one used in the human participants. The authors found no relationship between sex and aerosol particle number; however, there were significant statistical relationships among age, BMI, and particle size.”

“When the U.S. cohort was divided by age and sex, grip strength-to-weight predicted mortality and cardiovascular disease only in adults aged 45 years and older, and associations tended to be stronger in men than in women.”

“They used a machine learning model to compute the expected death rates among the patients based on characteristics such as the patients' age, sex, median vitamin D levels, and whether they had diabetes. The timeframe for the data collection preceded the advent of vaccines against COVID-19.”

“The results revealed striking sex differences in how heart attacks occur: Among the 1,474 heart attacks, about two-thirds were caused by atherosclerotic disease. The rest involved oxygen-supply problems or other non-atherosclerotic mechanisms.”

“Acetaminophen use in pregnant rats and mice directly interfered with the fetal production of sex hormones and other steroids; perturbed immune function by excessive dampening of inflammation; and increased oxidative stress.”

“In a study of over 190,000 people tested for SARS-CoV-2, lower 25-hydroxyvitamin D levels were strongly associated with higher SARS-CoV-2 test positivity rates, despite race/ethnicity, age, sex, and latitude.”

“Glioblastoma is an aggressive form of brain cancer, and researchers are still working to understand how sex hormones influence its growth. A new study tested whether androgens, a group of hormones that includes testosterone, shape immune responses to this disease.”
