A disturbed communication between hypothalamic-pituitary-ovary axis and gut microbiota in female infertility: is diet to blame?

Female infertility is a multifactorial condition influenced by various genetic, environmental, and lifestyle factors. Recent research has investigated the significant impact of gut microbiome dysbiosis on systemic inflammation, metabolic dysfunction, and hormonal imbalances, which can potentially impair fertility. The gut-brain axis, a bidirectional communication system between the gut and the brain, also plays a significant role in regulating reproductive functions.

Background: Uganda has been confronted with a sustained influx of refugees for decades. This prompted the government to explore opportunities to integrate refugees into local service structures including its national health system. This paper chronicles the history of policies and strategies that have influenced the integration of refugees into the national health system in Uganda and investigates factors that impacted policy evolution and progression.

CRYβB2 alters cell adhesion to promote invasion in a triple-negative breast cancer cell line.

Objective: African American women with breast cancer experience disproportionately poor survival outcomes, primarily due to the high prevalence of the deadliest subtype; triple-negative breast cancer (TNBC). The CRYβB2 gene is upregulated in tumors from African American patients across all breast cancer subtypes, including TNBC, and is associated with worse survival rates. This study investigated the effect of CRYβB2 on the invasion of TNBC cells and the underlying mechanisms contributing to this phenotype.

Hepatitis C Treatment in Kentucky Medicaid Recipients with Concurrent Opioid Use Disorder: A Cross-Sectional Study.

Background: Hepatitis C virus (HCV) infections and injection drug use have concurrently increased in the last decade. Evidence supports simultaneously treating chronic HCV and opioid use disorder (OUD) with medication. Kentucky is a hard-hit state for both conditions that has undertaken policy and practice efforts to increase access to both types of medications.

Epidemiology of Coronavirus Disease 2019-Associated Fungal Infections in the Intensive Care Unit: A Single-Center Retrospective Study.

Introduction: Invasive fungal disease (IFD) is a morbid superinfection that can arise in critically ill patients with COVID-19 infection. Studies evaluating the full spectrum of COVID-19-associated fungal infections remain limited.

Methods: Single-center retrospective study assessing IFD in patients with COVID-19, hospitalized for ≥ 72 h in the intensive care unit (ICU) between 02/25/20 and 02/28/22 (n = 1410).

Integrated analysis of genetic, proteinic, and metabolomic alterations in Behcet's disease.

Numerous studies have investigated the alterations of genes, proteins, and metabolites in Behcet's disease (BD). By far, little is known about the depiction of panoramic changes underlying this disease. This study purposed to assess the consistently dysregulated genes, proteins, and metabolites in BD across publications using the vote-counting approach.

Feasibility of an < 24 h discharge pathway with tele-monitoring after elective colectomies: a pilot study.

Introduction: Implementation of enhanced recovery after surgery principles has led to exploration of ambulatory pathways in surgery, including gastrointestinal surgery. However, implementation of ambulatory pathways after colorectal surgery has not been established yet. Previous studies suggest that discharge within 24 h in colorectal surgery is only possible with a clear protocol and careful patient selection.

Identification of potent TMPRSS4 inhibitors through structural modeling and molecular dynamics simulations.

TMPRSS4, a transmembrane serine protease type II, is associated with various pathological illnesses. It has been found to activate SARS-CoV-2, enhance viral infection of human small-intestinal enterocytes and is overexpressed in different types of cancers. Therefore, this study aims to disover potential TMPRSS4 inhibitors that have better binding affinity than the approved inhibitors: 2-hydroxydiarylamide and tyroserleutide.

MRI features that predict progression of residual disease after ablation of extra-abdominal desmoid fibromatosis.

Objective: To identify MRI features of desmoid tumors (DTs) that predict the growth of residual disease following ablation.

Methods: Patients who underwent MRI-guided ablation for DTs between February 2013 and April 2021 were included in this single-center IRB-approved retrospective study. MRI scans assessed three suspicious tissue features: intermediate T2 signal [+iT2], nodular appearance [+NOD], and contrast enhancement [+ENH].

Artificial neural network detection of pancreatic cancer from proton (1H) magnetic resonance spectroscopy patterns of plasma metabolites.

Background: Routine screening to detect silent but deadly cancers such as pancreatic ductal adenocarcinoma (PDAC) can significantly improve survival, creating an important need for a convenient screening test. High-resolution proton (1H) magnetic resonance spectroscopy (MRS) of plasma identifies circulating metabolites that can allow detection of cancers such as PDAC that have highly dysregulated metabolism.

Methods: We first acquired 1H MR spectra of human plasma samples classified as normal, benign pancreatic disease and malignant (PDAC).

Modeling of magnetic vestibular stimulation experienced during high-field clinical MRI.

Background: High-field magnetic resonance imaging (MRI) is a powerful diagnostic tool but can induce unintended physiological effects, such as nystagmus and dizziness, potentially compromising the comfort and safety of individuals undergoing imaging. These effects likely result from the Lorentz force, which arises from the interaction between the MRI's static magnetic field and electrical currents in the inner ear. Yet, the Lorentz force hypothesis fails to explain observed eye movement patterns in healthy adults fully.

One carbon metabolism supplementation in maturation medium but not embryo culture medium improves the yield of blastocysts from bovine oocytes.

Optimizing oocyte maturation and embryo culture media could enhance in vitro embryo production. The purpose of the present study was to investigate the role of supplementing one carbon metabolism (OCM) substrates and its cofactors (Cystine, Zinc, Betaine, B2, B3, B6, B12 and 5-methyltetrahydrofolate) in maturation and/or embryo culture media on the rate of blastocyst formation and pregnancy outcomes following the transfer of the resulting blastocysts in bovines. In the first experiment, 2537 bovine oocytes were recovered from slaughterhouse ovaries and then matured either in conventional maturation medium (IVM) or IVM supplemented with OCM substrates (Sup-IVM).

Dengue dynamics, predictions, and future increase under changing monsoon climate in India.

The global burden of dengue disease is escalating under the influence of climate change, with India contributing a third of the total. The non-linearity and regional heterogeneity inherent in the climate-dengue relationship and the lack of consistent data makes it difficult to make useful predictions for effective disease prevention. The current study investigates these non-linear climate-dengue links in Pune, a dengue hotspot region in India with a monsoonal climate and presents a model framework for predicting both the near-term and future dengue mortalities.

Racial/ethnic differences in post-acute sequelae of SARS-CoV-2 in children and adolescents in the United States.

Racial/ethnic differences are associated with the symptoms and conditions of post-acute sequelae SARS-CoV-2 infection (PASC) in adults. These differences may exist among children and warrant further exploration. We conducted a retrospective cohort study with difference-in-differences analyzes to assess these differences in children and adolescents under the age of 21.

Time to HIV viral rebound and frequency of post-treatment control after analytical interruption of antiretroviral therapy: an individual data-based meta-analysis of 24 prospective studies.

The only current strategy to test efficacy of novel interventions for sustained HIV control without antiretroviral therapy (ART) among people with HIV (PWH) is through an analytical treatment interruption (ATI). Inclusion of 'placebo' controls in ATIs poses ethical, logistical, and economic challenges. To understand viral dynamics and rates of post-treatment control (PTC) after ATI among PWH receiving either placebo or no intervention, we undertook an individual-participant data meta-analysis.

Risk factors influencing cage retropulsion following lumbar interbody fusion in treating degenerative lumbar diseases: A comprehensive systematic review and meta-analysis.

Background: Degenerative lumbar diseases (DLDs) often have significant impacts on patients' quality of life, particularly when cage retropulsion (CR) occurs following lumbar interbody fusion (LIF). In this study, we conducted a meta-analysis to assess the risk factors associated with CR after LIF.

Methods: We retrieved literatures analyzing the risk factors associated with CR following LIF from seven databases.

Durability of response of UGN-101: Longitudinal follow up of multicenter study.

Purpose: UGN-101, a reverse thermal mitomycin gel for upper tract instillation, recently became the first FDA approved treatment for upper tract urothelial carcinoma (UTUC). However, the durability of UGN-101 treatment has not been well described. Here we present long term outcomes from our multi-institutional cohort for patients who initially responded to treatment.

Repetitive grooming behavior following aversive stimulus coincides with a decrease in anterior hypothalamic area activity.

The anterior hypothalamic area (AHA) is a key brain region for orchestrating defensive behaviors. Using in vivo calcium imaging in mice, we observed that AHA neuronal activity increases during foot shock delivery and foot-shock associated auditory cues. We found that following shock-induced increases in AHA activity, a decrease in activity coincides with the onset of grooming behavior.

Local regulation of striatal dopamine release shifts from predominantly cholinergic in mice to GABAergic in macaques.

Dopamine critically regulates neuronal excitability and promotes synaptic plasticity in the striatum, thereby shaping network connectivity and influencing behavior. These functions establish dopamine as a key neuromodulator, whose release properties have been well-studied in rodents but remain understudied in nonhuman primates. This study aims to close this gap by investigating the properties of dopamine release in macaque striatum and comparing/contrasting them to better-characterized mouse striatum, using ex vivo brain slices from male and female animals.
