BACKGROUND: Annual chlamydia (CT) screening is recommended for women younger than 25 years, yet less than half of young women seeking health care are screened annually. We analyzed Title X family planning service data from the Northwest United States to assess factors associated with missed opportunities for CT screening. Our primary hypothesis was screening coverage is higher during annual preventive health visits compared to other visit types. Study objectives were: (1) identify gaps in screening coverage by patient demographics, visit characteristics, and clinic measures; and (2) examine the association between visit type and CT screening by controlling for other covariates and stratifying by state...

INTRODUCTION: Abnormally invasive placenta (AIP) involves abnormal adherence of the placenta to the myometrium, and is associated with severe pregnancy complications such as blood transfusion and hysterectomy. Knowledge of outcomes has been limited by small sample sizes and a focus on maternal rather than neonatal outcomes. This study uses population-level data collected over ten years to investigate maternal and neonatal outcomes and trends in incidence of AIP (also known as placenta accreta, increta and percreta)...

Invasive group A streptococcal (iGAS) infections cause severe disease and death, especially in residents of long-term care facilities (LTCFs). In order to inform iGAS prevention, we compared the risk of iGAS in LTCF residents and community residents. We identified LTCF residents among cases of iGAS from national surveillance (2009-2010) using postcode matching, and cases of hospital-acquired infections via hospital admission records. We used Poisson regression to calculate incidence rate ratios (IRR) and logistic regression to explore factors associated with case fatality rate (CFR)...

Using molecular simulation for adsorbent screening is computationally expensive and thus prohibitive to material discovery. Machine learning (ML) algorithms trained on fundamental material properties can potentially provide quick and accurate methods for screening purposes. Prior efforts have focused on structural descriptors for use with ML. In this work, the use of chemical descriptors, in addition to structural descriptors, was introduced for adsorption analysis. Evaluation of structural and chemical descriptors coupled with various ML algorithms, including decision trees, Poisson regression, support vector machine and random forest, were carried out to predict methane uptake on hypothetical metal organic frameworks...
