Machine Perfusion for Recovery of Brain Death Donor Hearts from Extended Distances.

The emerging ex vivo machine perfusion (MP) enables the extension of ex situ intervals, potentially expanding the heart transplant (OHT) donor pool. From October 18, 2018, to June 30, 2023, isolated OHT using donation after brain death (DBD) from extended distances (>500 miles) were identified in the United Network for Organ Sharing database, and categorized into cold storage (non-MP, N = 1,212) and MP group (N = 152). The MP utilization rate for DBD hearts from extended distances surged from 0% in 2018 to 27.

Common variable immunodeficiency clinical manifestations are shaped by presence and type of heterozygous NFKB1 variants.

Background: NFKB1 encodes p105, which is processed to p50 to mediate canonical NF-κB signaling. Though NF-κB is a central driver of inflammation and heterozygous NFKB1 variants are considered the most common monogenic etiologies of common variable immunodeficiency (CVID), few studies have explored how NFKB1 variants shape clinical course or inflammation in CVID.

Objective: We leveraged a regional cohort of CVID patients with and without heterozygous NFKB1 variants to assess how clinical and inflammatory features of CVID are shaped by the presence of these variants.

Applications of ChatGPT in Heart Failure Prevention, Diagnosis, Management, and Research: A Narrative Review.

Heart failure (HF) is a leading cause of mortality, morbidity, and financial burden worldwide. The emergence of advanced artificial intelligence (AI) technologies, particularly Generative Pre-trained Transformer (GPT) systems, presents new opportunities to enhance HF management. In this review, we identified and examined existing studies on the use of ChatGPT in HF care by searching multiple medical databases (PubMed, Google Scholar, Medline, and Scopus).

Axillary artery access considerations in Impella 5.5 insertion: Insights from exclusive axillary approach for successful support.

Background: The Impella 5.5® is commonly inserted via the axillary artery (AX) in patients with cardiogenic shock. The right AX has traditionally been preferred to avoid crossing the aortic arch, and a minimum diameter of 7 mm has been recommended to accommodate the device (21 Fr).

Acceptance of a third COVID-19 vaccine dose, vaccine interchangeability, and clinical trial enrolment among parents of children 12-17 years in Lima, Perú.

Objectives: To characterize factors associated with parental willingness for their children participation in a COVID-19 vaccine trial, use of different COVID-19 vaccines and acceptance of a third vaccine dose.

Methods: Parents of children aged 12-17 years in Lima, Perú were asked to complete an online questionnaire via social networks, from November 9, 2021, to April 23, 2022. We calculated crude and adjusted prevalence ratios with 95% confidence intervals to compare factors with the mentioned outcomes.

Revealing New Prospects: Antipsychotic Drugs Exert Anti-Tumor Effects against Gastric Cancer through Inducing Apoptosis.

Background And Objective: Globally, Gastric Cancer (GC) ranks as the fifth leading cause of cancer-related deaths. GC is a multifaceted malignancy with diverse etiologies; however, understanding the shared molecular mechanisms can aid in discovering novel targeted therapies for GC. This study has employed a drug repositioning approach to explore new drug candidates for treating GC.

Frequency of periprocedural myocardial injury and infarction stratified by cardiac troponin I and cardiac troponin T.

Background: There are different definitions of periprocedural myocardial infarction (PPMI) both in terms of thresholds for cardiac biomarkers and the ancillary criteria for myocardial ischemia. Cardiac Troponin I (cTnI) and cardiac Troponin T (cTnT) are used interchangeably to diagnose PPMI.

Objectives: This study evaluated the frequency of periprocedural myocardial injury and infarction as defined by the Society of Cardiovascular Angiography & Interventions (SCAI), the Academic Research Consortium-2 (ARC-2), and the 4th Universal definition of MI (4UDMI) stratified using cTnT versus cTnI, among patients with chronic coronary syndrome (CCS) and unstable angina.

Induction and maintenance of sequential intravesical gemcitabine/docetaxel for intermediate and high-risk non-muscle invasive bladder cancer with different dosage protocols.

Introduction: The combination of sequential intravesical gemcitabine and docetaxel (Gem/Doce) chemotherapy has been considered a feasible option for BCG (Bacillus Calmette-Guérin) treatment in non-muscle invasive bladder cancer (NMIBC), gaining popularity during BCG shortage period. We seek to determine the efficacy of the treatment by comparing Gem/Doce induction alone vs induction with maintenance, and to evaluate the treatment outcomes of two different dosage protocols.

Methods: A bi-center retrospective analysis of consecutive patients treated with Gem/Doce for NMIBC between 2018 and 2023 was performed.

Humoral Correlates of Protection Against Influenza A/H3N2 Virus Infection.

Background: Influenza virus remains a threat to human health, but gaps remain in our knowledge of the humoral correlates of protection against influenza virus A/H3N2, limiting our ability to generate effective, broadly protective vaccines. The role of antibodies against the hemagglutinin (HA) stalk, a highly conserved but immunologically subdominant region, has not been established for influenza virus A/H3N2.

Methods: Household transmission studies were conducted in Managua, Nicaragua, across 3 influenza seasons.

Stage B Heart Failure Is Ubiquitous in Emergency Patients with Asymptomatic Hypertension.

Introduction: Hypertension is the leading risk factor for morbidity and mortality throughout the world and is pervasive in United States emergency departments (ED). This study documents the point prevalence of subclinical heart disease in emergency patients with asymptomatic hypertension.

Method: This was a prospective observational study of ED patients with asymptomatic hypertension conducted at two urban academic EDs that belong to an eight-hospital healthcare organization in New York.

Consensus reporting guidelines to address gaps in descriptions of ultra-rare genetic conditions.

Genome-wide sequencing and genetic matchmaker services are propelling a new era of genotype-driven ascertainment of novel genetic conditions. The degree to which reported phenotype data in discovery-focused studies address informational priorities for clinicians and families is unclear. We identified reports published from 2017 to 2021 in 10 genetics journals of novel Mendelian disorders.

Pharmacy-based CLIA-waived testing in the United States: Trends, impact, and the road ahead.

Background: Federal authorization of the use of Clinical Laboratory Improvement Amendments of 1988 (CLIA) waived point-of-care tests for SARS-CoV-2 by pharmacists during the pandemic resulted in a dramatic rise in the number of community pharmacies that became CLIA-waived test sites. Now as we exit the pandemic, the wide-ranging expansion of the scope of practice facilitated currently by the PREP Act is set to expire in fall 2024. As a result, American pharmacists' ability to offer CLIA-waived testing services will revert to a patchwork of state laws.

Urinary glyphosate levels and association with mortality in the 2013-16 National Health and Nutrition Examination Survey.

Objectives: Glyphosate is the most commonly used herbicide in the USA; however, its safety is still under debate. We assessed glyphosate levels and their association with overall mortality in a representative sample of the US adult population from the 2013 to 2016 National Health and Nutrition Examination Survey.

Methods: We extracted data on urinary glyphosate (N = 2910) measured by ion chromatography isotope-dilution tandem mass spectrometry.

Vaginal microbes alter epithelial transcriptomic and epigenomic modifications providing insight into the molecular mechanisms for susceptibility to adverse reproductive outcomes.

The cervicovaginal microbiome is highly associated with women's health with microbial communities dominated by spp. being considered optimal. Conversely, a lack of lactobacilli and a high abundance of strict and facultative anaerobes including , have been associated with adverse reproductive outcomes.

Drug Discovery in Low Data Regimes: Leveraging a Computational Pipeline for the Discovery of Novel SARS-CoV-2 Nsp14-MTase Inhibitors.

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has led to significant global morbidity and mortality. A crucial viral protein, the non-structural protein 14 (nsp14), catalyzes the methylation of viral RNA and plays a critical role in viral genome replication and transcription. Due to the low mutation rate in the nsp region among various SARS-CoV-2 variants, nsp14 has emerged as a promising therapeutic target.
