Article Abstract

Background And Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) acts as an alternative for demarcating metabolic dysfunction-associated fatty liver disease (MAFLD). This study aimed to investigate the factors that significantly influence the relationship between MAFLD and MASLD in relation to the incidence of major cardiovascular outcomes.

Methods And Results: A total of 340,998 participants in the UK Biobank study were included. Multivariable Cox proportional hazards models were used to estimate the effect of MAFLD and MASLD on the outcomes of cardiovascular diseases (CVDs) (coronary artery disease, stroke, heart failure, and CVD-related death) with hazard ratios (HRs) and 95 % confidence intervals (CIs). A total of 126,077 (36.97 %) participants had MAFLD and 97,418 (28.57 %) had MASLD. Over a median follow-up of 13.5 years (interquartile range 12.6-14.2), there were 41,548 new events of CVDs recorded. MAFLD (HR = 1.52; 95 % CI: 1.49-1.55) and MASLD (HR = 1.42; 95 % CI: 1.39-1.45) were associated with high risks of CVDs. Among the subtypes of MAFLD and steatotic liver disease (SLD), MAFLD diabetes subtype (HR = 2.26; 95 % CI: 2.17-2.35) and alcohol-associated liver disease (ALD) (HR = 1.65; 95 % CI: 1.55-1.76) exhibited the highest risk of CVDs. MAFLD overweight without MD subtype were not associated with CVDs. The effect of MAFLD on the CVD outcomes was consistent regardless of the presence of MASLD.

Conclusion: The metabolic health status and alcohol consumption function as more critical factors than obesity in assessing CVD outcomes in participants with MAFLD or MASLD.

Background: Our study aimed to develop a predictive model for the risk of obstructive sleep apnea (OSA) in bariatric surgery candidates for utilization during the preoperative evaluation.

Methods: Relevant clinical data were retrospectively collected for 453 patients who met the inclusion criteria and did not meet the exclusion criteria; the patients were randomized into training and test cohorts. Univariate analysis was performed on the training set.

Ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, has transformed the management of mantle cell lymphoma (MCL) but is associated with an elevated risk of bleeding. We report a rare case of hepatic subcapsular hematoma due to ibrutinib in a patient with relapsed MCL. Ultrasound was crucial in the early detection, monitoring, and management of this rare but potentially severe complication.

Introduction: Bile duct injury (BDI) is a potentially devastating complication of cholecystectomy. Although the repair may be successful, patients often experience a decline in their quality of life (QoL). However, there is a paucity of data regarding the factors influencing long-term outcomes and QOL in these patients.

Magnetic Targeting of AAV Gene Therapy for Inner Ear Following Systemic Delivery: Preliminary Findings and Transduction Pattern in Rat Cochlea.

Biological Sciences Platform, Hurvitz Brain Sciences Program, Sunnybrook Research Institute, Sunnybrook Health Sciences Centre, 2075 Bayview Ave., Room M1 102, Toronto, ON, M4N 3M5, Canada.

Purpose: Delivery of therapeutics to the inner ear is complicated by their inaccessible location and the presence of the blood-labyrinth barrier that restricts most blood-borne compounds from entering the inner ear. This study addresses the challenge of optimal delivery in treating inner ear disease, focusing on magnetic targeting gene therapy using adeno-associated virus (AAV).

Methods: The investigation explores three AAV serotypes (AAV2 Quad Mut, AAV2 pANC80L65, and AAV9 PHP.

Objective: Dipeptidyl peptidase 9 (DPP9) not only regulates tumor progression and drug sensitivity, but also modifies oxidative stress mediated ferroptosis. This study aimed to investigate the effect of DPP9 inhibition on sorafenib sensitivity and its interaction with ferroptosis in hepatocellular carcinoma (HCC).

Methods: Two HCC cell lines (Huh7 and MHCC-97H) were transfected with DPP9 siRNA, followed by detection of reactive oxygen species (ROS), ferrous iron (Fe), malondialdehyde (MDA), and ferroptosis-related proteins, and treated by 0-16 μM sorafenib to calculate half-maximal inhibitory concentration (IC) for sensitivity assessment.
