Formalin-fixed paraffin-embedded tissue (FFPET), which is the most widely used pathology archive, usually has low-quality DNA and RNA due to extensive nucleic acid crosslinking. RNA fluorescence in situ hybridization (RNA-FISH) has been increasingly utilized in research and clinical settings to diagnose disease pathology. In this study, the effect of RNA degradation over archival time on RNA-FISH signals in FFPET and fresh frozen tissue (FFT) was systematically assessed.

Article Synopsis
  • A study was conducted to assess the effectiveness of Tixagevimab-Cilgavimab in immunocompromised children and adolescents weighing between 20 to >40 kg, with two different dosage groups based on weight (300 mg for 20 to <40 kg and 600 mg for ≥40 kg).
  • After measuring antibody levels at multiple time points, results showed that both dosages produced high levels of neutralizing antibodies against the ancestral SARS-CoV-2 strain, significantly surpassing levels in healthy children who had received three BNT162b2 vaccinations.
  • Adverse effects were mild and slightly more common in the heavier dosage group; overall, the study concluded that the lower dosage was just as effective as the higher

This sub-study sought to characterize the pharmacokinetics (PK) of favipiravir (FPV) within Thai adults and quantitatively assess differences in exposure to those previously reported in other populations as a basis to understand putative differences in efficacy between studies conducted in different regions. It was nested within a prospective trial of adults with symptomatic COVID-19 infection without pneumonia receiving 1800 mg FPV twice-daily on day 1 and 800 mg twice-daily thereafter. Individual PK profiles were fitted with a one-compartment disposition model (first-order absorption).

Background And Purpose: In large vessel occlusion (LVO) stroke patients, relative cerebral blood flow (rCBF)<30% volume thresholds are commonly used in treatment decisions. In the early time window, nearly infarcted but salvageable tissue volumes may lead to pretreatment overestimates of infarct volume, and thus potentially exclude patients who may otherwise benefit from intervention. Our multisite analysis aims to explore the strength of relationships between widely used pretreatment CT parameters and clinical outcomes for early window stroke patients.

There is continued interest in acceleration (G) effects in civil aviation, as G-induced loss of consciousness (G-LOC), impaired consciousness, and visual effects play a role in aerobatic, agricultural, and military aviation accidents. A software model [the Civil Aerospace Medical Institute G-Effects Model (CGEM)] based on physical and physiological variables related to in-flight tissue resupply and using oxygen flow as a proxy for supply availability, was developed to evaluate risk of G-LOC and related phenomena in aeronauts. Aeronauts were modeled using several parameters, including sex, cardiovascular fitness, and other common modifiers such as G-suits, positive pressure breathing gear, anti-G straining, and other muscle tensing.
