The persistence or emergence of long-term symptoms following resolution of primary SARS-CoV-2 infection is referred to as long COVID or post-acute sequelae of COVID-19 (PASC). PASC predominantly affects the cardiovascular, neurological, respiratory, gastrointestinal, reproductive, and immune systems. Among these, the central nervous system (CNS) is significantly impacted, leading to a spectrum of symptoms, including fatigue, headaches, brain fog, cognitive impairment, anosmia, hypogeusia, neuropsychiatric symptoms, and peripheral neuropathy (neuro-PASC).

Einstein (Sao Paulo)
December 2024
Objective: To evaluate the risk factors for healthcare-related infections during the COVID-19 pandemic in intensive care units, to investigate the impact of COVID-19 on Central Line-Associated Bloodstream Infection, Catheter-Associated Urinary Tract Infection, and ventilator-associated pneumonia, and to describe healthcare-associated infections in the waves of the COVID-19 pandemic.
Methods: This nested case-control study was conducted in a 137-bed adult medical/surgical intensive care unit at a private hospital in São Paulo, Brazil, between January 11, 2019, and May 21, 2022. Case patients were identified using the Nosocomial Infection Control Committee database and control patients were identified using the intensive care unit's EPIMED system.
Article Synopsis
- Economic development in the Jaguaribe River region has led to the release of various anthropogenic pollutants, indicating a growing environmental risk.
- A bibliographic review identified 38 pollutants in sediment and 7 in aquatic organism tissues, while ecotoxicological bioassays revealed lethal and sublethal effects on various test organisms.
- The study highlights significant risks to aquatic ecosystems and human health due to exposure to these contaminants, emphasizing the need for ongoing monitoring and pollution control measures.
Duration of aversive memory in zebrafish after a single shock.
Prog Neuropsychopharmacol Biol Psychiatry
October 2024
Article Synopsis
- Memory studies have gained traction due to various factors affecting memory performance, including stress, age, and drugs, with zebrafish becoming a popular model for understanding memory behaviors.
- Researchers conducted an experiment to assess the duration of long-term memory in zebrafish, finding that they could avoid an area of their tank associated with an unpleasant shock for up to 7 days after training.
- Treatment with MK-801, which blocks certain receptors, hindered the zebrafish's ability to recall the aversive memory, highlighting the potential for zebrafish in modeling cognitive impairments and advancing our understanding of memory mechanisms.
Background: Menezes et al. describe their experience with the diagnosis and management of disruptive medical staff behavior in a private hospital between 2020 and 2022. Surgical medical specialties were found to demonstrate the highest prevalence of such behavior, and continual education of physicians regarding appropriate workplace behavior was found to be the most important management strategy to prevent unsafe work environments and strengthen an appropriate culture of safety.
