Safety of spinal anesthesia and analysis of cerebrospinal fluid in SARS-CoV-2 pregnant women undergoing cesarean section: an observational prospective study.

Background: Systemic infection has always been considered a relative contraindication to neuraxial anesthesia, despite the fact that infectious complications are relatively uncommon. Pregnancy-related physiological changes and coronavirus disease (COVID-19) neurotropic features may facilitate the virus' entry into the central nervous system. The principal aim of this study was to test the safety of spinal anesthesia in "severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2)-positive pregnant women and to examine cerebrospinal fluid (CSF) characteristics.

Antibiotic Treatment of Superinfection in Patients With SARS-CoV-2 Infection Admitted to Intensive Care Unit: An Observational Retrospective Study.

Introduction: In COVID-19 patients on mechanical ventilation, VAP from remains a crucial risk factor for death. Antibiotic resistance represents an important problem in treating this infection. This study aims to describe the evolution of the superinfection from in patients with acute respiratory failure from SARS-CoV-2 infection admitted to ICU and compare the impact of two different antibiotic strategies on microbiological negativization.

Solubility of folic acid and protonation of folate in NaCl at different concentrations, even in physiological solution.

The solubility of folic acid was determined at 25 °C in 1.00 mol dm and in 0.15 mol dm NaCl (physiological solution) spectrophotometrically by measuring the absorbance of saturated solution at different hydrogen ion concentrations.

Behavior of glutathione as ligand of lead (II).

The presence and mobilization of toxic metal cations represents under many aspects a current and important problem in the environmental field. In this research, as cation lead (II) ion was studied. The formation of complexes between glutathione and lead (II) was studied at 25 °C and in 1.

Comparison between cocoa and chocolate: characterisation and fatty acid content.

The connection between chocolate and cocoa is studied. As cocoa is produced in different countries, samples coming from the same geographical region are analysed. The analyses focus on the characterisation of the considered samples for different aspects of quality and to individuate the original locations of production, also connecting this with the nutritional aspects.
