Vortioxetine versus reuptake inhibitors in adults with major depressive disorder: A systematic review and meta-analysis of randomized controlled trials.

Background: Although vortioxetine demonstrates superior efficacy relative to placebo, there is still a lack of robust evidence to determine whether it offers advantages over commonly prescribed antidepressants for treating major depressive disorder (MDD). Thus, we aimed to perform a systematic review and meta-analysis comparing vortioxetine vs reuptake inhibitors in adults with MDD, analyzing two classes separately: (i) vortioxetine vs SSRIs and (ii) vortioxetine vs SNRIs.

Methods: We searched MEDLINE, Embase, and Cochrane Library databases for randomized controlled trials comparing vortioxetine with SSRIs or SNRIs in adults with a primary diagnosis of MDD following standardized diagnostic criteria.

Effects of Kinesio tape on vascularity, pliability and height of the hypertrophic scar in burns patients: a randomized pilot clinical trial.

Deep burns damage the reticular dermis and may lead to the formation of hypertrophic scars. Compression therapy reduces local vascularity and realigns collagen fibers, resulting in esthetic and functional improvements. This study evaluated the effect of Kinesio tape compression with maximum mechanical tension on vascularity, pliability and the height of hypertrophic scars following deep burns.

Analysis of spelling errors from the 'dyslexic sight words' list.

In this study the spelling errors of the 'Dyslexic Sight Words - DSW' list are analyzed according to the semiological classification. The spelling errors were made by schoolchildren with and without dyslexia. The high number of inaccuracies observed in the writing of the Group with dyslexia (GD) was often related to the complexity of syllabic structures and orthographic irregularity.

Sustainable production of bioemulsifiers, a critical overview from microorganisms to promising applications.

Microbial bioemulsifiers are molecules of amphiphilic nature and high molecular weight that are efficient in emulsifying two immiscible phases such as water and oil. These molecules are less effective in reducing surface tension and are synthesized by bacteria, yeast and filamentous fungi. Unlike synthetic emulsifiers, microbial bioemulsifiers have unique advantages such as biocompatibility, non-toxicity, biodegradability, efficiency at low concentrations and high selectivity under different conditions of pH, temperature and salinity.
