Factors Associated with Occurrence of Stillbirth before 32 Weeks of Gestation in a Contemporary Cohort.

Objective: We sought to quantify the distribution of stillbirths by gestational age (GA) in a contemporary cohort and to determine identifiable risk factors associated with stillbirth prior to 32 weeks of gestation.

Study Design: Population-based case-control study of all stillbirths in the United States during the year 2014, utilizing vital statistics data, obtained from the National Center for Health Statistics. Distribution of stillbirths were stratified by 20 to 44 weeks of GA, in women diagnosed with stillbirth in the antepartum period.

Tissue transport affects how treatment scheduling increases the efficacy of chemotherapeutic drugs.

A method to predict the effect of tissue transport on the scheduling of chemotherapeutic treatment could increase efficacy. Many drugs with desirable pharmacokinetic properties fail in vivo due to poor transport through tissue. To predict the effect of treatment schedule on drug efficacy we developed an in silico method that integrates diffusion through tissue and cell binding into a pharmacokinetic model.

Microfluidic Device to Quantify the Behavior of Therapeutic Bacteria in Three-Dimensional Tumor Tissue.

Microfluidic devices enable precise quantification of the interactions between anti-cancer bacteria and tumor tissue. Direct observation of bacterial movement and gene expression in tissue is difficult with either monolayers of cells or tumor-bearing mice. Quantification of these interactions is necessary to understand the inherent mechanisms of bacterial targeting and to develop modified organisms with enhanced therapeutic properties.

Persistent enhancement of bacterial motility increases tumor penetration.

Motile bacteria can overcome the transport limitations that hinder many cancer therapies. Active bacteria can penetrate through tissue to deliver treatment to resistant tumor regions. Bacterial therapy has had limited success, however, because this motility is heterogeneous, and within a population many individuals are non-motile.

Lessons in translation: insights from a collaboration integrating community health workers into diabetes care.

Beginning in 2007, a community health center and a community health worker organization collaborated on a community health worker initiative to improve diabetes outcomes among underserved communities. Despite a shared vision, the initiative ended prematurely because of a number of unexpected collaborative challenges. This article describes the results of a qualitative investigation into these challenges.
