Barriers to Bariatric Surgery: a Mixed Methods Study Investigating Obstacles Between Clinic Contact and Surgery.

Purpose: Populations most affected by obesity are not reflected in the patients who undergo bariatric surgery. Gaps in the referral system have been studied, but there is a lack of literature investigating obstacles patients encounter after first contact with bariatric surgery clinics. We aim to identify patient populations at risk for attrition during bariatric surgery evaluation and determine patient reported barriers to bariatric surgical care.

Effects of extreme potassium stress on blood pressure and renal tubular sodium transport.

We characterized mouse blood pressure and ion transport in the setting of commonly used rodent diets that drive K intake to the extremes of deficiency and excess. Male 129S2/Sv mice were fed either K-deficient, control, high-K basic, or high-KCl diets for 10 days. Mice maintained on a K-deficient diet exhibited no change in blood pressure, whereas K-loaded mice developed an ~10-mmHg blood pressure increase.
