Stroke patterns and outcomes during the second wave of COVID-19 pandemic: a cross-sectional study.

Unlabelled: The coronavirus disease 2019 (COVID-19) pandemic has affected the number of stroke activations, admission of patients with various types of strokes, the rate and timely administration of reperfusion therapy, and all types of time-based stroke-related quality assessment metrics. In this study, we describe the different types of strokes, different delays in seeking and completing treatment occurring during the second wave of the COVID-19 pandemic, and predictors of outcome at 3 months follow-up.

Materials And Methods: This is a single-centered prospective cross-sectional study carried out from May 2021 to November 2021, enrolling patients with stroke.

Anxiety and depression among nurses in COVID and non-COVID intensive care units.

Background: Frontline nurses dealing with the coronavirus disease-2019 (COVID-19) pandemic face various mental health challenges ranging from excessive stress and anxiety to severe depression.

Aims: To study the comparative prevalence of anxiety and depression, and their contributing factors, between nurses working in intensive care units (ICU) with COVID-19 patients (COVID ICU) and nurses working in ICU with patients admitted for other reasons (non-COVID ICU).

Design: Quantitative comparative cross-sectional study.

Effect of storage on survival of infectious Treponema pallidum spiked in whole blood and platelets.

Background: Blood donations must be tested for evidence of syphilis, a transfusion-transmitted infection. Screening blood for syphilis-related antibodies greatly reduced the risk of transfusion-transmitted syphilis (TTS). It is commonly believed that Treponema pallidum (Tp), the bacterium causing syphilis, does not survive in blood during cold storage-suggested as one reason why no cases of TTS have been recognized in the United States for many years.

Air-Evacuation-Relevant Hypobaria Following Traumatic Brain Injury Plus Hemorrhagic Shock in Rats Increases Mortality and Injury to the Gut, Lungs, and Kidneys.

Rats exposed to hypobaria equivalent to what occurs during aeromedical evacuation within a few days after isolated traumatic brain injury exhibit greater neurologic injury than those remaining at sea level. Moreover, administration of excessive supplemental O2 during hypobaria further exacerbates brain injury. This study tested the hypothesis that exposure of rats to hypobaria following controlled cortical impact (CCI)-induced brain injury plus mild hemorrhagic shock worsens multiple organ inflammation and associated mortality.

Targeted lipopolysaccharide biosynthetic intermediate analysis with normal-phase liquid chromatography mass spectrometry.

Lipopolysacharride (LPS) forms the outer leaflet of the outer membrane in Gram-negative bacteria and contributes to the permeability barrier and immune response. In this study, we established a method for monitoring the LPS biosynthetic intermediates of the Raetz pathway (lpxA-lpxK) in Escherichia coli. Metabolites from compound-treated cells and genetically-perturbed cells were extracted from whole cells and concentrated by mixed-mode weak anion exchange (WAX) solid-phase extraction (SPE) prior to analysis by normal phase (NP)LC-MS/MS.
