Spontaneous occurrence of placental glutathione S-transferase (GST-P)-positive foci was observed in the livers of 5-month-old LEC rats. Quantitative studies revealed that GST-P foci appeared after the onset of hepatitis. The number and size of GST-P foci increased with age and more foci were induced in males than in females. No sex difference, however, was found in the incidence of hepatitis. Although hepatitis is necessary for the induction of GST-P foci, it is insufficient for their further growth. Since hereditary hepatitis first appears at around 4 months of age, leading to a high incidence of hepatocellular carcinomas in later life, the spontaneous occurrence of the foci may be related to the development of hepatocellular carcinoma.

Global regional and national burden of intracerebral hemorrhage between 1990 and 2021.

Intracerebral hemorrhage (ICH) represents one of the most devastating forms of stroke, characterized by spontaneous bleeding into the brain parenchyma. This neurological emergency carries a substantial burden of mortality and long-term disability worldwide. A comprehensive understanding of ICH's evolving global impact from 1990 to 2021 remains essential for healthcare planning and resource allocation.

Objectives: In this descriptive study, we aimed to assess how the index mode of birth and subsequent birth modes vary over time for public and private hospital maternity care funding models. The second aim was to determine to what extent the index mode of birth predicts subsequent birth modes in general and whether this differs in public versus private hospital maternity care funding models. With our aim, we have an innovative approach, specifically the women's life course approach, which is hypothesis-generating and can be assessed in future studies.

Background Aims: SBP leads to high rates acute kidney injury (AKI) -hepatorenal syndrome and mortality. Population-based studies on contemporary SBP epidemiology are needed to inform care. In a large, national cohort of patients diagnosed with SBP and confirmed by ascitic fluid criteria, we characterized ascitic fluid characteristics, in-hospital and 12-month mortality, AKI, and recurrent SBP.

Objective: Although the efficacy of high-flow nasal oxygen therapy in delaying or avoiding intubation in patients with hypoxemic respiratory failure has been studied, its potential for facilitating early weaning from invasive mechanical ventilation remains unexplored.

Methods: In this randomized controlled trial, 80 adults with acute hypoxemic respiratory failure requiring invasive mechanical ventilation for > 48 hours were enrolled and divided into two groups: conventional weaning and early weaning via high-flow nasal oxygen. In the conventional weaning group, the spontaneous breathing trial was performed after the PaO2/FiO2 ratio was ≥ 200, whereas in the high-flow nasal oxygen group, the spontaneous breathing trial was conducted earlier when the PaO2/FiO2 ratio was 150 - 200.
