Hinge Position Dominance Over Osteotomy Inclination in Medial Open-Wedge High Tibial Osteotomy: A Key Factor in Posterior Tibial Slope Changes.

Objective: A medial open-wedge high tibial osteotomy (MOWHTO) may increase the posterior tibial slope (PTS). The purpose of this study was to determine the effect of the osteotomy inclination angle (in the sagittal plane) in combination with different hinge positions (in the transverse plane) on the change in PTS due to a MOWHTO.

Methods: We developed a mathematical approach to determine the effect of the osteotomy inclination angle combined with different hinge positions.

Plasma Matrix Metalloproteinase-9 Predicts Intraoperative Experience and Extent of Resection in Vestibular Schwannoma Surgery.

Objective: To evaluate the predictive value of plasma matrix metalloproteinase-9 (MMP-9) level in determining the extent of tumor resection (EOR) and tumor adherence in vestibular schwannoma (VS) surgery.

Study Design: Prospective cohort study.

Setting: Academic referral center.

Factors protecting against progression of myopia in school students exposed to societal change in Vietnam: a 3-year cohort study.

Objectives: To elucidate the incidence of myopia, progression of refractive error, axial length (AL) elongation and factors associated with myopia in secondary school students in Vietnam.

Design: Prospective cohort study.

Settings: Hue Healthy Adolescent Cohort Study, Hue City, Vietnam.

Self-Activated Energy Release Cascade from Anthracene-Based Solid-State Molecular Solar Thermal Energy Storage Systems.

We introduce donor-acceptor substituted anthracenes as effective molecular solar thermal energy storage compounds that operate exclusively in the solid state. The donor-acceptor anthracenes undergo visible light-induced [4+4] cycloaddition reaction, producing metastable cycloadducts, dianthracenes with quaternary carbons, and storing photon energy. The triggered cycloreversion of dianthracenes to anthracenes discharges the stored energy as heat in the order of 100 kJ/mol (200 J/g).

Burden and Risk Factors of Stroke in Vietnam from 1990 to 2021 - A Systematic Analysis from Global Burden Disease 2021.

Background: Stroke is a leading cause of death in Vietnam. However, a comprehensive analysis of stroke burden remains limited. This study aims to investigate the burden of stroke and various risk factors in Vietnam from 1990 to 2021.
