A Comparison of Neonatal Outcomes Between Obese and Nonobese Women With Preterm Prelabor Rupture of Membranes.

Introduction Preterm prelabor rupture of membrane (PPROM) contributes to increasing rates of preterm birth, causing greater health risks for newborns. While the mechanisms driving PPROM are not well understood, one hypothesis is that it is due to systemic inflammation, which can be caused by obesity defined as a BMI [Formula: see text]30 kg/m. The specific aim of the study was to compare neonatal outcomes after PPROM between patients who were obese vs not obese in early pregnancy at a tertiary medical center serving an Appalachian population.

The Case for Advocacy Curricula and Opportunities in Medical Education: Past Examples to Inform Future Instruction.

With recent advances in understanding racial, socioeconomic, and mental health issues in medicine and their relation to policy and legislation, medical professionals are increasingly involved in local and national advocacy efforts. At the frontlines of these initiatives are medical students who, in addition to completing required coursework and clinical training, devote themselves to serving patients through civic participation. The burgeoning evidence concerning health care disparities and inequity, along with greater awareness of racial and socioeconomic discrimination, have made advocacy an essential aspect of many students' medical training.

Prevalence and Spatial Distribution of Gastroschisis in an Industrial Watershed.

The relationship between the congenital defect of gastroschisis and environmental toxins is poorly understood. We examined gastroschisis incidence, risk factors, and spatial association in a geographic region with known environmental pollution and hazardous waste sites. An observational study of fetal and neonatal gastroschisis diagnosed from 1/1/2006 to 12/31/2020 was conducted in a southern West Virginia (WV) tertiary care hospital.

Perinatal outcomes in women referred to the West Virginia University Assist Connect and Encourage (ACE) - A program of the Drug Free Moms and Babies Project (DFMB) for women with substance use during pregnancy.

The main objective of this study was to analyze perinatal outcomes of women with substance use disorder in pregnancy who participated in the West Virginia University Medicine Drug Free Moms and Babies Assist Connect and Encourage program (DFMB/ACE) compared to women who were not enrolled in the program. This was a retrospective cohort study conducted in an l Academic Tertiary Care Center. Women who enrolled in DFMB/ACE services from 2018 to 2019 were termed as the intervention group.

What MFTs should know about nutrition, psychosocial health, and collaborative care with nutrition professionals.

Despite sufficient evidence on the role of nutrition in psychosocial health, Marriage and Family Therapists lack the knowledge for sufficient assessment and referrals in treatment. The purpose of this article is to orient MFTs to human metabolism and the effects of various nutrients, or lack thereof, on the psychosocial health in their clients. The roles of several micronutrients and macronutrients will be described as well as the effects of eating patterns and overall metabolic health on mental health.

Intermediate filaments enable pathogen docking to trigger type 3 effector translocation.

Type 3 secretion systems (T3SSs) of bacterial pathogens translocate bacterial effector proteins that mediate disease into the eukaryotic cytosol. Effectors traverse the plasma membrane through a translocon pore formed by T3SS proteins. In a genome-wide selection, we identified the intermediate filament vimentin as required for infection by the T3SS-dependent pathogen S.

Infectious Entry Pathway Mediated by the Human Endogenous Retrovirus K Envelope Protein.

Unlabelled: Endogenous retroviruses (ERVs), the majority of which exist as degraded remnants of ancient viruses, comprise approximately 8% of the human genome. The youngest human ERVs (HERVs) belong to the HERV-K(HML-2) subgroup and were endogenized within the past 1 million years. The viral envelope protein (ENV) facilitates the earliest events of endogenization (cellular attachment and entry), and here, we characterize the requirements for HERV-K ENV to mediate infectious cell entry.

A mechanistic paradigm for broad-spectrum antivirals that target virus-cell fusion.

LJ001 is a lipophilic thiazolidine derivative that inhibits the entry of numerous enveloped viruses at non-cytotoxic concentrations (IC50 ≤ 0.5 µM), and was posited to exploit the physiological difference between static viral membranes and biogenic cellular membranes. We now report on the molecular mechanism that results in LJ001's specific inhibition of virus-cell fusion.

N-Glycans on the Nipah virus attachment glycoprotein modulate fusion and viral entry as they protect against antibody neutralization.

Nipah virus (NiV) is the deadliest known paramyxovirus. Membrane fusion is essential for NiV entry into host cells and for the virus' pathological induction of cell-cell fusion (syncytia). The mechanism by which the attachment glycoprotein (G), upon binding to the cell receptors ephrinB2 or ephrinB3, triggers the fusion glycoprotein (F) to execute membrane fusion is largely unknown.

Endothelial galectin-1 binds to specific glycans on nipah virus fusion protein and inhibits maturation, mobility, and function to block syncytia formation.

Nipah virus targets human endothelial cells via NiV-F and NiV-G envelope glycoproteins, resulting in endothelial syncytia formation and vascular compromise. Endothelial cells respond to viral infection by releasing innate immune effectors, including galectins, which are secreted proteins that bind to specific glycan ligands on cell surface glycoproteins. We demonstrate that galectin-1 reduces NiV-F mediated fusion of endothelial cells, and that endogenous galectin-1 in endothelial cells is sufficient to inhibit syncytia formation.

A quantitative and kinetic fusion protein-triggering assay can discern distinct steps in the nipah virus membrane fusion cascade.

The deadly paramyxovirus Nipah virus (NiV) contains a fusion glycoprotein (F) with canonical structural and functional features common to its class. Receptor binding to the NiV attachment glycoprotein (G) triggers F to undergo a two-phase conformational cascade: the first phase progresses from a metastable prefusion state to a prehairpin intermediate (PHI), while the second phase is marked by transition from the PHI to the six-helix-bundle hairpin. The PHI can be captured with peptides that mimic F's heptad repeat regions, and here we utilized a NiV heptad repeat peptide to quantify PHI formation and the half-lives (t(1/2)) of the first and second fusion cascade phases.

Private sector response to improving oral health care access.

Despite vast improvements in the oral health status of the United States population over the past 50 years, disparities in oral health status continue, with certain segments of the population carrying a disproportionate disease burden. This article attempts to describe the problem, discuss various frameworks for action, illustrate some solutions developed by the private sector, and present a vision for collaborative action to improve the health of the nation. No one sector of the health care system can resolve the problem.
