School closures, child maltreatment reporting and victimization during the pandemic.

Background: School closures during the pandemic correlated with declines in child maltreatment reports in the U.S. However, it remains unclear how reporting from personnel other than schoolteachers or nurses and the nature of these reports were affected.

Everything feels just a little heavier, more wrought with implications, you know? - a mixed-methods study examining lifestyle behaviors, health, and well-being of pregnant and postpartum women during the early months of the COVID-19 pandemic.

Background: While the striking impact of the COVID-19 pandemic on mental health, heath care access and lifestyle behaviors, including perceived health, diet, physical activity, and sleep has been reported, few studies have examined these domains jointly among pregnant and postpartum people in the early stages of the COVID-19 pandemic.

Methods: This mixed methods study was conducted among a subset of participants (n = 22) in a cohort study in Austin, Texas, who were pregnant or had recently delivered when the outbreak occurred. Measures were from the early second trimester up to 6 months postpartum.

Systematic comparison of quantity and quality of RNA recovered with commercial FFPE tissue extraction kits.

Background: FFPE tissue samples are commonly used in biomedical research and are a valuable source for next-generation sequencing in oncology, however, extracting RNA from these samples can be difficult the quantity and quality achieved can impact the downstream analysis. This study compared the effectiveness of seven different commercially available RNA extraction kits specifically designed for use with FFPE samples in terms of the quantity and quality of RNA recovered.

Methods: This study used 9 samples of FFPE tissue from three different types of tissue (Tonsil, Appendix and lymph node of B-cell lymphoma) to evaluate RNA extraction methods.

Effectiveness of AZD7442 (Tixagevimab/Cilgavimab) for Pre-Exposure Prophylaxis Against COVID-19 Hospitalization in Israel During the Omicron Sub-Variant Time Period.

Introduction: The effectiveness of AZD7442 (tixagevimab/cilgavimab) against COVID-19 hospitalizations was determined at 3 and 6 months among immunocompromised individuals in Israel during different variant circulations.

Methods: This was a retrospective cohort study using data from Clalit Health Services in Israel. Immunocompromised individuals eligible to receive AZD7442 300 mg between 15 February and 11 December 2022 were identified.

Brain energy homeostasis: the evolution of the astrocyte-neuron lactate shuttle hypothesis.

The brain's substantial metabolic requirements, consuming a substantial fraction of the body's total energy despite its relatively small mass, necessitate sophisticated metabolic mechanisms for efficient energy distribution and utilization. The astrocyte-neuron lactate shuttle (ANLS) hypothesis has emerged as a fundamental framework explaining the metabolic cooperation between astrocytes and neurons, whereby astrocyte-derived lactate serves as a crucial energy substrate for neurons. This review synthesizes current understanding of brain energy metabolism, focusing on the dual roles of lactate as both an energy substrate and a signaling molecule.
