Problem: Recurrent vulvovaginal candidiasis (RVVC) affects 5%-10% of all women, negatively impacting their reproductive health and quality of life. Herein, we investigated the molecular effects of RVVC on the vaginal mucosa of otherwise healthy women.
Method Of Study: Gene expression analysis was performed on vaginal tissue biopsies from women with RVVC, including those with a current episode of vulvovaginal candidiasis (VVC, n = 19) and women between infections (culture negative RVVC [CNR], n = 8); women asymptomatically colonized with Candida albicans (asymptomatic [AS], n = 7); and healthy controls (n = 18).
The injectable contraceptive, depot medroxyprogesterone acetate (DMPA), is associated with compromised cervical mucosal barriers. High-resolution spatial transcriptomics is applied here to reveal the spatial localization of these altered molecular markers. Ectocervical tissue samples from Kenyan sex workers using DMPA, or non-hormonal contraceptives, underwent spatial transcriptomics and gene set enrichment analyses.

However, of the 11% patients reporting a penicillin allergy (PA), most receive second-line, non-β-lactam prophylaxis. Previously, abdominal wall reconstruction research from our institution demonstrated increased wound complications, readmissions, and reoperations with non-β-lactam prophylaxis.

Methods: A collaborative multicenter cross-sectional study to evaluate the sensitivity and specificity of the combination of two tests (α-GAL enzyme activity assay and lyso-GL3 assay) for the diagnosis of FD in women.
The endoplasmic reticulum (ER) lumen is not only the major site for the assembly and folding of newly synthesized proteins but also the main intracellular Ca store. Ca ions are involved in versatile biochemical processes, including posttranslational processing and folding of nascent proteins. Disruption of ER Ca homeostasis is usually accompanied by an ER stress response that can ultimately lead to apoptosis if unresolved.

This study evaluated the effectiveness of video messaging on VCA donation willingness in US military veterans, a key stakeholder in VCA transplantation.
Methods: Participants (n = 556) were randomized to 1 of 3 VCA video messaging interventions (informational, testimonial, or blended), a general (non-VCA) organ donation video message, or a control (nondonation) video message.
Aberrant activity of the SUMOylation pathway has been associated with MYC overexpression and poor prognosis in aggressive B-cell lymphoma (BCL) and other malignancies. Recently developed small-molecule inhibitors of SUMOylation (SUMOi) target the heterodimeric E1 SUMO activation complex (SAE1/UBA2). Here, we report that activated MYC signaling is an actionable molecular vulnerability in vitro and in a preclinical murine in vivo model of MYC-driven BCL.

Several studies have shown that the individual ELMO proteins are involved in a variety of cellular and developmental processes. However, it has poorly been understood whether the Elmo proteins show similar functions and act redundantly.

Starting from a targeted screening for SUMO-regulated immune evasion mechanisms, we identified an evolutionarily conserved function of activated SUMOylation, which attenuated the immunogenicity of tumor cells. Activated SUMOylation allowed cancer cells to evade CD8+ T cell-mediated immunosurveillance by suppressing the MHC class I (MHC-I) antigen-processing and presentation machinery (APM).

In this study, we investigate whether knockout of pdx1 also leads to diabetic kidney disease (DKD). pdx1-/- larvae exhibit several signs of early DKD, such as glomerular hypertrophy, impairments in the filtration barrier corresponding to microalbuminuria, and glomerular basement membrane (GBM) thickening.

In zebrafish, knockout of the main MG detoxifying system Glyoxalase 1, led to limited MG elevation but significantly elevated aldehyde dehydrogenases (ALDH) activity and aldh3a1 expression, suggesting the compensatory role of Aldh3a1 in diabetes. To evaluate the function of Aldh3a1 in glucose homeostasis and diabetes, aldh3a1 zebrafish mutants were generated using CRISPR-Cas9.

Methods: Over a 17-month period, a convenience sample of 1517 veterans in New England completed a survey to assess attitudes about organ, tissue, and vascularized composite allograft (VCA) donation.
Results: Most veterans (96%) supported the donation of organs and tissue for transplantation, and 59% were registered as an organ and tissue donor.
Various β-galactosidase enzymes catalyze the trans-glycosylation reaction with lactose. The resulting galactooligosaccharide (GOS) mixtures are widely used in infant nutrition to stimulate growth of beneficial gut bacteria. GOS consists mainly of compounds with a degree of polymerization (DP) varying from 2-8 and with diverse glycosidic linkages.

To evaluate the effectiveness of video messaging on adolescent organ donor designation rates. We randomized adolescent driver education classes in Massachusetts, between July 2015 and February 2018, to receive 1 of 3 organ donation video messaging interventions (informational, testimonial, or blended). Adolescents completed questionnaires before and after the intervention and at 1-week follow-up; we compared their registration status at time of obtaining driver's license with that of a regionally matched historical comparison group.

Unlabelled: Alarming trends in antibiotic resistance sparked a National Action Plan endorsing antimicrobial stewardship programs (ASPs) in health care facilities. Atrium Health consists of 28 acute care facilities with varying levels of ASP maturity. The organization sought to establish an ASP collaborative across a diverse network by uniting local resources with a central advisory team.

Bacteroides thetaiotaomicron is a prominent human colon commensal bacterial species that hydrolyzes GOS using an extracellular Glycosyl Hydrolase (GH) family GH53 endo-galactanase enzyme (BTGH53), releasing galactose-based products for growth. Here we dissect the molecular basis for GOS activity of this B.

Here, we show that these GL34 compounds are largely resistant to the hydrolytic activities of common carbohydrate-degrading enzymes. Also, the ability of single strains of gut bacteria, bifidobacteria, lactobacilli, and commensal bacteria, to ferment the GL34 compounds was studied.

Objective: To analyze the hearing and tinnitus in normal-hearing workers exposed to occupational noise.
Objective: To describe the experience of parenting a child diagnosed with cancer by examining particularly negative and positive experiences reported by parents of childhood cancer survivors and parents of children lost to cancer.
Methods: 168 parents (88 mothers, 80 fathers) participated. Data were collected five years after the end of successful treatment or the child's death.
Background: Early appropriate antibiotic selection is associated with favorable clinical outcomes. We evaluated the clinical impact of rapid detection of vancomycin-resistant Enterococcal bacteremia (VREB) by the FilmArray blood culture identification (BCID) panel coupled with antimicrobial stewardship program (ASP) interventions.
Methods: Hospitalized adult patients with VREB identified by conventional methods (CM) were compared to patients with VREB identified by BCID.
Background: Increased understanding of the relationships between different symptom clusters involved in posttraumatic stress symptoms (PTSS) could guide empirical research and clinical practice. The objective of the present study was to investigate whether hyperarousal and avoidance mediated the relationship between re-experiencing and dysphoria in parents of children diagnosed with cancer.
Methods: Longitudinal data from parents of children receiving cancer therapy were used.
Exopolysaccharides (EPS) of lactic acid bacteria (LAB) are of interest for food applications. LAB are well-known to produce α-glucan from sucrose by extracellular glucansucrases. Various Lactobacillus reuteri strains also possess 4,6-α-glucanotransferase (4,6-α-GTase) enzymes.
