The study highlights exercise and caloric restriction as valid treatment strategies for this prevalent condition, which affects 23% of adults in the US.
A new study published in PLoS Medicine suggests that antidepressants only provide clinically significant benefits for a small group of severely depressed patients. However, even among these patients, the improvement is not very great, and depressed people can still improve without chemical treatments.
A study found that US adults have a higher prevalence of stroke than Europeans, mainly due to higher rates of stroke risk factors in the US. The gap is more pronounced among poor Americans, who are more likely to have a stroke.
A meta-analysis of 34 clinical trials found venlafaxine (SNRI) outperformed SSRIs in treating depression, resulting in a 5.9% increased remission rate. This translates to the need for doctors to treat 17 patients with venlafaxine to achieve one patient's benefit.

A new study reveals that acculturation can have varying effects on men and women's drinking habits along the Texas-Mexico border. Researchers found that immigrant groups who acculturate to mainstream America tend to experience more alcohol-related problems, but this impact differs by gender.
The use of clinical trials to inform Medicare coverage decisions disproportionately affects older women with comorbid conditions, differing significantly from the target population. This disparity highlights the need for more representative trial populations to ensure better value and improved outcomes for Medicare beneficiaries.
