Gba1 E326K renders motor and non-motor symptoms with pathological α-synuclein, tau and glial activation.

Mutations in the GBA1 gene are common genetic risk factors for Parkinson's disease, disrupting enzymatic activity and causing lysosomal dysfunction, leading to elevated α-synuclein levels. Although the role of GBA1 in synucleinopathy is well established, recent research underscores neuroinflammation as a significant pathogenic mechanism in GBA1 deficiency. This study investigates neuroinflammation in Gba1 E326K knock-in mice, a model associated with increased risk of Parkinson's disease and dementia.

Comparison of 2 curative treatment options for very early hepatocellular carcinoma: Efficacy, recurrence pattern, and retreatment.

Curative treatments for very early-stage hepatocellular carcinoma (HCC), defined as single HCC with a maximum diameter of <2 cm in patients with well-preserved liver function, consist of surgical resection or radiofrequency ablation (RFA). In this retrospective study, we compared the efficacy of both treatments in 154 patients with very early-stage HCCs who underwent resection or RFA as initial therapy and were followed up for a median of 56.8 months.

Preadmission Statin Use and 90-day Mortality in the Critically Ill: A Retrospective Association Study.

Background: This study aimed to examine the association between preadmission statin use and 90-day mortality in critically ill patients and to investigate whether this association differed according to statin type and dose. We hypothesized that preadmission statin use was associated with lower 90-day mortality.

Methods: This retrospective cohort study analyzed the medical records of all adult patients admitted to the intensive care unit in a single tertiary academic hospital between January 2012 and December 2017.

Preadmission chronic opioid usage and its association with 90-day mortality in critically ill patients: a retrospective cohort study.

Background: The aim of this study was to investigate the association of chronic opioid usage with 90-day mortality in critically ill patients after admission to the ICU.

Methods: This retrospective cohort study analysed the medical records of adult patients admitted to ICUs in a tertiary academic hospital between January 2012 and December 2017. Patients taking opioids regularly for more than 4 weeks before ICU admission were defined as chronic opioid users, whereas the others were defined as opioid-naïve patients.

Retrospective analysis of 30-day unplanned readmission after major abdominal surgery with reversal by sugammadex or neostigmine.

Background: Sugammadex is associated with fewer postoperative complications, but its impact on 30-day unplanned readmission is unclear.

Methods: This was a single-centre retrospective observational study of patients after major abdominal surgery between 2010 and 2017, where rocuronium was the only neuromuscular blocker used. The primary endpoint was the difference in incidence of 30-day unplanned readmission between reversal with sugammadex or neostigmine.
