Given the large and increasing number of uninsured US individuals, identifying the health consequences of being uninsured has assumed increased importance. ⋯ Among individuals who experienced a health shock caused by an unintentional injury or a new chronic condition, uninsured individuals reported receiving less medical care and poorer short-term changes in health than those with insurance.

Randomized Controlled Trial Comparative Study
Comparison of the Atkins, Zone, Ornish, and LEARN diets for change in weight and related risk factors among overweight premenopausal women: the A TO Z Weight Loss Study: a randomized trial.
Popular diets, particularly those low in carbohydrates, have challenged current recommendations advising a low-fat, high-carbohydrate diet for weight loss. Potential benefits and risks have not been tested adequately. ⋯ In this study, premenopausal overweight and obese women assigned to follow the Atkins diet, which had the lowest carbohydrate intake, lost more weight at 12 months than women assigned to follow the Zone diet, and had experienced comparable or more favorable metabolic effects than those assigned to the Zone, Ornish, or LEARN diets [corrected] While questions remain about long-term effects and mechanisms, a low-carbohydrate, high-protein, high-fat diet may be considered a feasible alternative recommendation for weight loss.

Mortality in randomized trials of antioxidant supplements for primary and secondary prevention: systematic review and meta-analysis.
Antioxidant supplements are used for prevention of several diseases. ⋯ Treatment with beta carotene, vitamin A, and vitamin E may increase mortality. The potential roles of vitamin C and selenium on mortality need further study.

Randomized Controlled Trial Multicenter Study Comparative Study
Cognitive behavioral therapy for posttraumatic stress disorder in women: a randomized controlled trial.
The prevalence of posttraumatic stress disorder (PTSD) is elevated among women who have served in the military, but no prior study has evaluated treatment for PTSD in this population. Prior research suggests that cognitive behavioral therapy is a particularly effective treatment for PTSD. ⋯ Prolonged exposure is an effective treatment for PTSD in female veterans and active-duty military personnel. It is feasible to implement prolonged exposure across a range of clinical settings.
