Exercise More, Sit Less to Manage Frailty and Hypertension Risk in Aging

A new study of middle-age and older adults looks at sex differences in frailty levels and their link with heart health. The findings suggest that moving your body more through regular exercise and sitting less can help keep both heart disease and frailty at bay as we age.

Rare Human Gene Variant in ADHD, Autism Exposes Fundamental Sex Differences

Key differences in male and female mice brains provide new insights into how sex determines the mechanisms by which distinct synapses monitor and regulate dopamine signaling. The impact of sex differences is particularly pronounced when the mice express a human genetic variant found in boys with either ADHD or autism. Behavioral generalizations across the sexes may limit diagnosis of mental illness, especially if one sex translates alterations into outward signs such as hyperactivity and aggression vs. more internal manifestations such as learning, memory and mood, even when the same molecular pathology is at work.

Drugs Effects of Ketamine in Mice can Depend on the Sex of the Human Experimenter

Researchers at the University of Maryland School of Medicine have shown that mice respond more to the antidepressant effects of the drug ketamine when administered by men and not by women. The group demonstrated that a stress response detected in the mouse’s brain from handling by a man is essential for ketamine to work.

When it Comes to Preventing Alzheimer’s, Women and Men are Not Created Equal

A study is the first to examine if sex significantly affects cognitive outcomes in people who follow individually-tailored, multi-domain clinical interventions. The study also determined whether change in risk of developing cardiovascular disease (CVD) and Alzheimer’s disease (AD), along with blood markers of AD risk, also were affected by sex. Results showed that while care in an Alzheimer’s Prevention Clinic setting is equally effective at improving cognitive function in both women and men, the personally-tailored interventions used by the researchers led to greater improvements in women compared to men across AD and CVD disease risk scales, as well blood biomarkers of risk such as blood sugar, LDL cholesterol, and the diabetes test HbA1C. Findings are important because women are disproportionately affected by AD and population-attributable risk models suggest that managing risk factors can prevent up to one-third of dementia cases.

Women: Lower-fat Diet Key to Liver Health Following Weight-loss Surgery

Research suggests that women who have weight loss surgery need to reduce the amount of fat they eat after surgery to reap the full benefit of the procedure and protect their liver function. The study is published ahead of print in the American Journal of Physiology-Endocrinology and Metabolism.

When seeing is believing

Being able to vividly imagine graduating college predicts grade point average and whether a student continues in a STEM or business degree program, according to a longitudinal study from Arizona State University. The study also found sex differences between how men and women visualized their post-graduation goals: Men increased the level of detail, but women remained stagnant. These findings could have implications for why women are underrepresented in STEM and business careers.

Brain Disease Research Reveals Differences Between Sexes

In APL Bioengineering, University of Maryland scientists highlight a growing body of research suggesting sex differences play roles in how patients respond to brain diseases, as well as multiple sclerosis, motor neuron disease, and other brain ailments. They are urging their colleagues to remember those differences when researching treatments and cures.

Kidney Replacement Therapy Rates Have Remained Higher in Men Vs. Women for Decades

• Rates for all types of kidney replacement therapy in European countries were consistently higher in men than women from 1965 to 2015.
• Male-to-female ratios increased with age, showing consistency over decades and for individual countries, despite changes in the causes of kidney disease.
• The male-to-female ratio was higher for kidney transplantation in diabetic patients.

New Diagnostic Criteria May Enable Earlier Detection of Cognitive Impairment in Women

Study finds when verbal memory test cut-offs were tailored to patient sex, more female patients and fewer male patients were considered to have amnesic mild cognitive impairment. This could change the way aMCI diagnoses are determined and make it easier to catch the condition in its early stages.
