PROJECT PREVENT: a randomized controlled trial of preoperative vaginal metronidazole to decrease patient issues and infections after hysterectomy.

Objectives: To evaluate if vaginal metronidazole for 5 days before hysterectomy decreases postoperative infections and patient issues.

Design: This randomized trial compared vaginal metronidazole for 5 days before a scheduled hysterectomy to no intervention. Sample size calculation was based on a 20% difference in issues and infection (30% incidence and 10% in the intervention arm) with 80% power and an alpha error of 0.

The Variation of Chargemaster Price Listings for Urogynecologic Procedures.

Importance: A 2018 Executive Order calling for price transparency required hospitals to publicly provide chargemasters, which are detailed lists of standard price listings for billable medical procedures.

Objectives: The objective of this study was to evaluate price listing variations in common urogynecology procedures.

Study Design: This was a cross-sectional study of chargemasters obtained between February and April 2020 from hospitals across 5 states chosen to reflect the diversity of health systems in the United States.

Chargemaster Pricing Variation for Commonly Billed Procedures in Interventional Cardiology.

Objectives: A chargemaster is a database of all of the billable items offered by a hospital with their base price listings. A 2018 executive order required all American hospitals to publish their chargemasters to increase price transparency and reduce healthcare expenditures. Chargemaster listings, however, demonstrate marked variability and inconsistency and have not been associated with consumer benefit.

A Preliminary Investigation of the Effects of a Western Diet on Hippocampal Volume in Children.

Over the course of the 20th century, there has been a sharp increase in the consumption of saturated fat and refined sugars. This so-called "western diet" (WD) has been extensively linked to biological alterations and associated functional deficits in the hippocampus of animals. However, the effects of a WD on the human hippocampus are less well-characterized.
