[Analysis of the first two years of the COVID-19 pandemic in an infectious diseases hospital in Buenos Aires].

Introduction: At the Muñiz Hospital, the Febrile Unit (UF) was established, a device that operates during the COVID-19 pandemic. Its implementation has demonstrated the importance of public policies in the health system, in addition to the possible development of epidemiological surveillance and monitoring strategies that provide health contributions. An analysis of the first two years of the pandemic at UF-Muñiz was carried out.

Effect of starvation and pesticide exposure on neutral lipid composition of the digestive gland of males of the apple snails Pomacea canaliculata.

Pollutants as well as starvation usually modify homeostasis of neutral lipids in aquatic organisms. However, studies on the simultaneous effects of both stressors are scarce. The aim of this study was to evaluate the effect of toxicant exposure under starvation conditions on neutral lipids of the freshwater snail Pomacea canaliculata, selected as the model organism.

[Treatment of drug-resistant tuberculosis in adults and children. A narrative review].

Since 2018, important changes in the treatment of drug-resistant tuberculosis have been produced in the light of new evidence. The discovery of new anti-tuberculosis drugs, such as bedaquiline and nitroimidazopirane derivatives, as well as the use of repurposed drugs, led to international organizations to recommend new, totally oral, treatment regimens for mono-resistant and multidrug-resistant tuberculosis, leaving aside the prolonged use of injectables, with their inherent toxicity and discomfort. Some definitions of drug-resistant tuberculosis have changed.

[The Febrile Emergency Unit at Muñiz Hospital facing COVID-19, HIV and tuberculosis].

Febrile Emergency Units were annexed to tertiary hospitals to face the pandemic caused by SARS CoV-2 in Buenos Aires City. We performed a retrospective observational study in order to evaluate the profile of people consulting the Unit annexed to the Muñiz Hospital, during the period comprising epidemiological weeks 28 to 42, 2020. The total number of consultations was 12 571; 6801 (54.

Nuclear-lipid-droplet proteome: carboxylesterase as a nuclear lipase involved in lipid-droplet homeostasis.

Nuclear-lipid droplets (nLD)-a dynamic cellular organelle that stores neutral lipids, within the nucleus of eukaryotic cells-consists of a hydrophobic triacylglycerol -cholesterol-ester core enriched in oleic acid (OA) surrounded by a monolayer of polar lipids, cholesterol, and proteins. nLD are probably involved in nuclear-lipid homeostasis serving as an endonuclear buffer that provides or incorporates lipids and proteins participating in signaling pathways, as transcription factors and enzymes of lipid metabolism and nuclear processes. In the present work, we analyzed the nLD proteome and hypothesized that nLD-monolayer proteins could be involved in processes similar as the ones occurring in the cLD including lipid metabolism and other cellular functions.
