Parallel single-cell metabolic analysis and extracellular vesicle profiling reveal vulnerabilities with prognostic significance in acute myeloid leukemia.
Nat Commun

Acute myeloid leukemia (AML) is an aggressive disease with a high relapse rate. In this study, we map the metabolic profile of CD34(CD38) AML cells and the extracellular vesicle signatures in circulation from AML patients at diagnosis. CD34 AML cells display high antioxidant glutathione levels and enhanced mitochondrial functionality, both associated with poor clinical outcomes.

Growth differentiation factor 15, GDF15, and glucagon-like peptide-1 (GLP-1) analogues act through brainstem neurons that co-localise their receptors, GDNF-family receptor α-like (GFRAL) and GLP1R, to reduce food intake and body weight. However, their use as clinical treatments is partially hampered since both can also induce sickness-like behaviours, including aversion, that are mediated through a well-characterised pathway via the exterolateral parabrachial nucleus. Here, in mice, we describe a separate pathway downstream of GFRAL/GLP1R neurons that involves a distinct population of brain-derived neurotrophic factor (BDNF) cells in the medial nucleus of the tractus solitarius.

December 2024
Interdisciplinary Department of Medicine, School of Medicine, University of Bari "Aldo Moro", Bari, Italy.
Background: Evidence indicates a wide range of andrological alterations in patients with the Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) infection and Coronavirus Disease 2019 (COVID-19).
Aim: To provide an update on the andrological effects of SARS-CoV-2 infection and COVID-19.
Methods: PubMed/MEDLINE and Institutional websites were searched for randomized clinical trials, non-systematic reviews, systematic reviews, and meta-analyses.
laparoscopy has emerged as a pivotal tool for the management of acute abdominal pathologies. It provides diagnostic and therapeutic advantages, enabling surgeons to evaluate and address diverse acute abdominal conditions using minimally invasive techniques. The aim of this consensus was to obtain evidence-based guidance for surgeons regarding the utilization of laparoscopy in emergency medical settings, and has been divided into trauma and non-trauma emergencies.

Cardiogenic shock (CS) in women is a serious cardiovascular (CV) event associated with a high mortality rate. Non-ischemic etiologies are the most common etiologies in women, such as stress-induced cardiomyopathy, peripartum/postpartum cardiomyopathy, heart failure-related CS, or CS due to myocarditis or valvular heart disease. Although not being the most common etiology in women, acute myocardial infarction is still an important one.
