In a study comparing sinusoidal wave and brief-pulse ECT in endogenous depression, seizure duration was monitored by the cuff method in 29 patients over 180 treatment sessions. Mean seizure duration across all treatments was 26.5 secs, and the mean for individual patients across their ECT course ranged from a minimum of 15.7 secs to maximum of38.5 secs. Regression analysis found no variable whi...

PURPOSE The use of anti-vascular endothelial growth factor (anti-VEGF) therapy, with drugs such as ranibizumab and bevacizumab, to treat neovascular age-related macular degeneration (nAMD) produces an effective but widely variable response. Identifying markers that predict differentiated response could serve as a valuable assay in developing more personalized medicine. This study aimed to ident...

background and objective: vascular endothelial growth factor (vegf) and its receptors (vegf-r1 and r2) are major regulators of angiogenesis. this study was designed to assess serum levels of vegf and vegf-r1 and their prognostic significance in newly diagnosed childhood acute leukemia. materials and methods: for this purpose, vegf and vegf-r1 were determined using enzyme linked immuno-sorbant a...

BACKGROUND We evaluated a new noninvasive ventilation (NIV) protocol that allows the pursuit of NIV in the case of persistent severe respiratory acidosis despite a first NIV challenge in COPD patients with acute hypercapnic respiratory failure (AHRF). PATIENTS AND METHODS A prospective observational multicentric pilot study was conducted in three tertiary hospitals over a 12-month study perio...
