Predictors and Outcomes of Right Ventricular Dysfunction in Patients Admitted to the Medical Intensive Care Unit for Sepsis-A Retrospective Cohort Study.

: Right ventricular (RV) dysfunction is associated with poor clinical outcomes in critically ill sepsis patients, but its pathophysiology and predictors are incompletely characterized. We aimed to investigate the predictors of RV dysfunction and its outcomes in sepsis patients admitted to the intensive care unit (ICU). : This is a single-center retrospective cohort study of adult patients admitted to the ICU for sepsis who had echocardiography within 72 h of diagnosis.

The Safety Profile of Inclisiran in Patients with Dyslipidemia: A Systematic Review and Meta-Analysis.

Introduction: Inclisiran is a novel drug that employs ribonucleic acid (RNA) interference to lower the levels of the proprotein convertase subtilisin/kexin type 9 (PCSK9) protein. It has demonstrated a significant reduction in LDL cholesterol levels compared to a placebo. We aim to comprehensively evaluate the safety of using Inclisiran in patients with dyslipidemia and ASCVD or an ASCVD risk equivalent.

Epidemiologic and clinical characteristics of infective endocarditis: a single-center retrospective study in the Bronx, New York.

Objective: There is paucity of data on the epidemiological, microbiological, and clinical characteristics of patients admitted with infective endocarditis (IE) in the Bronx, New York.

Patient And Methods: We conducted a retrospective study at Jacobi Medical Center, a tertiary care hospital in the Bronx. All adult patients who were hospitalized with a primary diagnosis of new-onset IE between January 1st, 2010 and September 30th, 2020 were included.

Cocaine challenge enhances release of neuroprotective amino acid taurine in the striatum of chronic cocaine treated rats: a microdialysis study.

Drug addiction is a serious public health problem. There is increasing evidence on the involvement of augmented glutamatergic transmission in cocaine-induced addiction and neurotoxicity. We investigated effects of acute or chronic cocaine administration and cocaine challenge following chronic cocaine exposure on the release of excitotoxic glutamate and neuroprotective taurine in the rat striatum by microdialysis.

Cortical plasticity in Alzheimer's disease in humans and rodents.

Background: The aim of this study was to determine whether neocortical long-term potentiation (LTP) is deficient in patients with Alzheimer's disease (AD) and in amyloid precursor protein (APP)/presenilin-1 (PS1) mice, an AD animal model. We then ascertained whether this deficit might be paralleled by functional abnormalities of N-methyl-D-aspartate (NMDAR) glutamate receptors.

Methods: We studied neocortical LTP-like plasticity in 10 patients with mild-to-moderate AD and 10 age-matched normal controls using paired associative stimulation (PAS).

Altered excitability and distribution of NMDA receptor subunit proteins in cortical layers of rat pups following multiple perinatal seizures.

During a critical period of postnatal development the epileptogenic focus is thought to be of cortical origin. We used immunohistochemistry and Western blotting to elucidate potential mechanisms underlying an increased state of susceptibility to seizures in immature animals. Distribution patterns of N-methyl-D-aspartic acid (NMDA) (NR1 and NR2A/B) and alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) (GluR1 and GluR2) subunits were analyzed in retrosplenial, parietal and temporal cortices during the first two postnatal weeks following three episodes of status-epilepticus.

Distinct regulation of metabotropic glutamate receptor (mGluR1 alpha) in the developing limbic system following multiple early-life seizures.

The effects of repeated neonatal seizures on metabotropic glutamate receptors (mGluRs) during critical periods of brain development are unknown. Therefore, we characterized the expression of Group I (mGluR1 and mGluR5) and Group II (mGluR2/3) metabotropic glutamate receptor proteins in the developing limbic system in response to a varied neonatal seizure history. Status epilepticus was induced with kainic acid (KA) either once (1x KA) on postnatal (P) day (P13), twice (2x KA) on P6 and P9 or P13, or three times (3x KA) on P6, P9, and P13.

Clozapine protection against gestational cocaine-induced neurochemical abnormalities.

Clozapine was found to be effective in attenuating cocaine-induced neurochemical effects. We investigate whether clozapine influences in utero cocaine exposure-induced changes in striatal dopamine levels and cortical N-methyl-D-aspartate (NMDA) receptor density in mouse and rat brains. Pregnant mice or rats were injected with cocaine (5 or 10 mg/kg intraperitoneally) or saline every 24 h throughout gestation and continued for 6 weeks following the delivery.
