Background: High levels of catecholamines are cardiotoxic and associated with stress-induced cardiomyopathies. Septic patients are routinely exposed to endogenously released and exogenously administered catecholamines, which may alter cardiac function and perfusion causing ischemia. Early during human septic shock, left ventricular ejection fraction (LVEF) decreases but normalizes in survivors over 7-10 days.

Ann Gastroenterol
December 2024
Department of Hepatology and Gastroenterology, CHU Saint-Pierre, Brussels, Belgium (Jennifer Aoun, Pierre Eisendrath).
Background: Various endoscopic treatment options are available for managing colonic diverticular bleeding (CDB). We conducted a systematic review and meta-analysis to assess the effectiveness of these endoscopic interventions in achieving hemostasis in patients with CDB, focusing on early rebleeding rate (ERR) within 30 days.
Methods: A systematic literature search of the PubMed and Cochrane Library databases was performed for articles published between January 2008 and December 2023.
Hazelnut oral immunotherapy desensitizes hazelnut but not other tree nut allergies (Nut CRACKER Study).

Institute of Allergy, Immunology and Pediatric Pulmonology, Yitzhak Shamir Medical Center; Department of Pediatrics, Faculty of Medicine, Tel Aviv University.
Background: Data on oral immunotherapy (OIT) for hazelnut allergy is limited and its potential to cross-desensitize for other nuts is unknown.
Objective: To study the efficacy and safety of hazelnut OIT in desensitizing hazelnut and additional tree nuts.
Methods: A prospective observational study of 30 hazelnut allergic patients aged ≥4 years who underwent hazelnut OIT.

Department of Pharmacology, Faculty of Medical Sciences, State University of Campinas (UNICAMP), Campinas, Brazil.
Background: 6-Nitrodopamine (6-ND) released from rat vas deferens acts an endogenous modulator of vas deferens contractility.
Objectives: To investigate whether rat isolated seminal vesicles (RISV) releases 6-ND, the mechanisms involved in the release, and the modulatory role of 6-ND on tissue contractility.
Methods: Rat seminal vesicles were removed and placed in Krebs-Henseleit's solution at 37°C for 30 min, and an aliquot was used to analyze the concentrations of 6-ND, dopamine, noradrenaline, and adrenaline by liquid chromatography with tandem mass spectrometry (LC-MS/MS).
