Multilevel Follow-up of Cancer Screening (mFOCUS): Protocol for a multilevel intervention to improve the follow-up of abnormal cancer screening test results.

Introduction: While substantial attention is focused on the delivery of routine preventive cancer screening, less attention has been paid to systematically ensuring that there is timely follow-up of abnormal screening test results. Barriers to completion of timely follow-up occur at the patient, provider, care team and system levels.

Methods: In this pragmatic cluster randomized controlled trial, primary care sites in three networks are randomized to one of four arms: (1) standard care, (2) "visit-based" reminders that appear in a patient's electronic health record (EHR) when it is accessed by either patient or providers (3) visit based reminders with population health outreach, and (4) visit based reminders, population health outreach, and patient navigation with systematic screening and referral to address social barriers to care.

Sialic acid levels in breast milk from HIV-positive Tanzanian women and impact of maternal diet.

Objective: To quantify total sialic acid in milk from HIV-positive Tanzanian mothers and to determine the impact of maternal diet on milk sialic acid levels.

Design: Milk samples were analyzed from 74 HIV-positive, Tanzanian women enrolled in a randomized, controlled clinical study of a dietary macronutrient supplement. Women were provided with a daily protein-calorie supplement and a micronutrient supplement or micronutrient supplement only during the last trimester of pregnancy and up to the first 6 months of breastfeeding.

Vibrio cholerae Outer Membrane Vesicles Inhibit Bacteriophage Infection.

Novel preventatives could help in efforts to limit infection and the spread of cholera. Bacteriophage (phage) treatment has been proposed as an alternative intervention, given the rapid replication of virulent phages, prey specificity, and relative ease of finding new virulent phages. Phage tropism is dictated in part by the presence of phage receptors on the bacterial surface.

Physician preference items: what factors matter to surgeons? Does the vendor matter?

Background: The USA devotes roughly $200 billion (6%) of annual national health expenditures to medical devices. A substantial proportion of this spending occurs during orthopedic (eg, hip and knee) arthroplasties - two high-volume hospital procedures. The implants used in these procedures are commonly known as physician preference items (PPIs), reflecting the physician's choice of implant and vendor used.
