Dangerous exposures to chemicals managed by Poison Centers all around the world during the COVID-19 pandemic: a systematic review and proportional meta-analysis.

Introduction: During COVID-19 pandemic, cleaning/disinfection activities were highly recommended. This study summarizes the state of art and estimates the prevalence of dangerous exposures to specific chemicals managed by Poison Centers (PCs) from all over the world during 2020 vs 2019, trying to overcome the critical aspects of the product categorization systems used by PCs.

Materials And Methods: A systematic research was conducted in 3 major databases and 2 websites of PCs associations.

Monitoring of alcohol-based hand rubs in SARS-CoV-2 prevention by HS-GC/MS and electrochemical biosensor: A survey of commercial samples.

Alcohol-based hand rubs (ABHRs) have found large diffusion during the Severe Acute Respiratory Syndrome Coronavirus 2, SARS-CoV-2, thus becoming the most widespread means for hand hygiene. Whereby, it is fundamental to assess the alignment of commercial ABHRs to the indications provided by the principal health agencies regarding alcohol content and possible impurities. In this work, a novel improvement of previous existent methods for the determination of alcohol content in such products was reported.

Comparison of ropivacaine plasma concentration after posterior Quadratus Lumborum Block in Cesarean Section with ropivacaine with epinephrine vs. plane.

Background: The posterior quadratus lumborum block (pQLB) has been used in postoperative pain management after cesarean section (CS). However, clinicians have no data about pQLB safety in pregnants, at increased risk of local anesthetic systemic toxicity (LAST). The purpose of the present study was to explore the efficacy and the safety of adding epinephrine to ropivacaine for bilateral pQLB vs.
