Associations Between Preconception Plasma Fatty Acids and Pregnancy Outcomes.

Background: Although fatty acids are involved in critical reproductive processes, the relationship between specific fatty acids and fertility is uncertain. We investigated the relationship between preconception plasma fatty acids and pregnancy outcomes.

Methods: We included 1,228 women attempting pregnancy with one to two previous pregnancy losses from the EAGeR trial (2007-2011).

Preconception Plasma Phospholipid Fatty Acids and Fecundability.

Context: Fatty acids (FAs) are important for reproductive processes, including steroidogenesis, though associations with fecundability, as measured by time to pregnancy (TTP), are unclear.

Objective: To investigate the relationship between preconception plasma phospholipid FA (PPFA) levels and time to human chorionic gonadotropin-pregnancy among women with prior pregnancy loss.

Design, Setting, And Participants: Prospective cohort of 1228 women attempting pregnancy (aged 18 to 40 years, with one or two prior pregnancy losses) followed for up to six cycles at four US university medical centers during 2006 to 2012.

Cutting Corners: Provider Perceptions of Interpretation Services and Factors Related to Use of an Ad Hoc Interpreter.

Introduction: This study assessed health providers' perceptions of factors related to professional interpretation services and the association between these factors and the potential use of ad hoc interpreters.

Method: Data were collected from a convenience sample of 150 health services providers at a large, regional health system in South Carolina.

Results: Providers rated "ability to communicate effectively during a clinical encounter" as paramount regarding the use of interpretation services.

Preparing for patient-centered care: assessing nursing student knowledge, comfort, and cultural competence toward the Latino population.

As the Latino population continues to grow throughout the United States, cultural competence training of nursing students at the baccalaureate level has become a priority. This study aimed to explore undergraduate nursing students' attitudes and beliefs toward Latino patients and their perceived readiness to provide care to Latino patients. A cross-sectional survey was conducted at four major nursing schools in the southeastern United States, which is the region that has seen the highest percentage of growth in the Latino population.

Salmonella-directed recruitment of new membrane to invasion foci via the host exocyst complex.

Salmonella attachment to the intestinal epithelium triggers delivery of bacterial effector proteins into the host cytosol through a type III secretion system (T3SS), leading to pronounced membrane ruffling and macropinocytic uptake of attached bacteria. The tip of the T3SS is made up of two proteins, SipB and SipC, which insert into the host plasma membrane, forming a translocation pore. Both the N and C termini of SipC are exposed in the host cytosol and have been shown to directly modulate actin cytoskeleton assembly.
