Supratentorial Intracranial Anomalies in Myelomeningocele Patients.

Aim: To assess associated cerebral supratentorial anomalies in patients who underwent myelomeningocele repair in hopes of developing a better morphological apprehension of the forebrain?s anomalies in this category of patients.

Material And Methods: This retrospective observational study assessed 426 pediatric patients who underwent myelomeningocele repair between January 2013 and December 2020. Cranial MRIs with T1- and T2-weighted sequences were obtained as part of the postoperative assessment to determine the presence of associated supratentorial anomalies in pediatric patients following myelomeningocele repair.

Task-dependent functional connectivity changes in response to varying levels of social support.

Background: Having social support improves one's health outcomes and self-esteem, and buffers the negative impact of stressors. Previous studies have explored the association between social support and brain activity, but evidence from task-dependent functional connectivity is still limited.

Aims: We aimed to explore how gradually decreasing levels of social support influence task-dependent functional connectivity across several major neural networks.

Predictors of anxiety and depression in operating room nurses during the COVID-19 pandemic: A multi-center cross-sectional study.

Background: Operating room nurses (ORNs) who directly deal with the treatment and care of COVID-19 patients during the pandemic are at risk in terms of psychological stress and other mental health problems.

Objective: The aim of the study was to compare the anxiety and depression levels of ORNs working in different countries in the COVID-19 outbreak, and to determine the predictors and the difference between countries.

Methods: This was a descriptive and cross-sectional study.

Gradual Loss of Social Group Support during Competition Activates Anterior TPJ and Insula but Deactivates Default Mode Network.

Group forming behaviors are common in many species to overcome environmental challenges. In humans, bonding, trust, group norms, and a shared past increase consolidation of social groups. Being a part of a social group increases resilience to mental stress; conversely, its loss increases vulnerability to depression.

Prenatal SARS-CoV-2 Spike Protein Exposure Induces Autism-Like Neurobehavioral Changes in Male Neonatal Rats.

Recent research on placental, embryo, and brain organoids suggests that the COVID-19 virus may potentially affect embryonic organs, including the brain. Given the established link between SARS-CoV-2 spike protein and neuroinflammation, we sought to investigate the effects of exposure to this protein during pregnancy. We divided pregnant rats into three groups: Group 1 received a 1 ml/kg saline solution, Group 2 received 150 μg/kg adjuvant aluminum hydroxide (AAH), and Group 3 received 40 μg/kg spike protein + 150 μg/kg AAH at 10 and 14 days of gestation.
