Object: To report the immediate and mid-term follow-up results of the Amplatzer membranous VSD occluder for the percutaneous occlusion of the perimembranous VSD.
Background: Percutaneous perimembranous VSD occlusion is still considered an experimental method where a variety of devices have been tested. Nowadays, more than 500 membranous Amplatzer devices have been implanted worldwide with encouraging results.
Method: We included 6 patients (1 man and 5 women) with a mean age of 9.9 years (range, 3 to 17.5) in whom percutaneous perimembranous VSD closure was attempted.
Results: In one of the patients, positioning of the device was not possible (intention to treat success rate, 83.3%). In the remaining five patients, there was a single defect. The VSD mean diameter with echo was 7 +/- 1.7 mm (range, 5.1 to 9) and with angio was 6.9 +/- 1 (range, 6 to 8). Mean pulmonary pressure was 20.2 +/- 7.7 mm Hg (range, 12-30) and Qp/Qs was 1.69 +/- 0.65 (range, 1.2-2.8). A single device was use in all cases. Immediate angiographic control showed complete occlusion in two patients, trivial shunt in one, and mild shunt in two. Follow-up was at least 4 months. Only one patient has residual trivial shunt, the rest of the defects are completely closed.
Conclusion: The special design of the Amplatzer membranous VSD occluder allows percutaneous closure of this defect in a safe and effective way, with good mid-term results. In selected cases, this is a good alternative to surgery in the treatmen of this cardiac defect.
Background: Traditional cognitive assessments, often reliant on paper-and-pencil tests and professional evaluators, suffer from subjectivity and limited result discrimination. This study introduces the Baguan Online Cognitive Assessment System (BOCAS), a tablet-based system that evaluates both general cognitive ability (GCA) and domain-specific functions across six domains: sensory-motor skills, processing speed, sustained attention, working memory, cognitive flexibility, and spatial ability.
Methods: BOCAS was validated with 151 healthy Chinese adults aged 18-40.
Nonalcoholic fatty liver disease (NAFLD) or metabolic dysfunction-associated steatotic liver disease (MASLD) is a significant global public health dilemma with wide-ranging social and economic implications. Diet and lifestyle modifications remain essential components of NAFLD management. The current study investigated the association between diet-related inflammation and NAFLD among 3110 Iranian adults participating in the Amol Cohort Study (AmolCS), employing the Structural Equation Modeling (SEM) approach.
Infection prevention and control (IPC) programs form the basis of minimizing spread of pathogens in the healthcare setting and beyond. The COVID-19 pandemic amplified the demand for IPC. However, the environmental impact of IPC practices has yet to be addressed and attempts to quantify its climate implications have been sparse.
Background: Youth involved in the legal system have disproportionately higher rates of problematic substance use than non-involved youth. Identifying and connecting legal-involved youth to substance use intervention is critical and relies on the connection between legal and behavioral health agencies, which may be facilitated by learning health systems (LHS). We analyzed the impact of an LHS intervention on youth legal and behavioral health personnel ratings of their cross-system collaboration.
