The objective of this study was to assess whether the standard therapy of ready-to-use therapeutic food in the treatment of uncomplicated severe acute malnutrition (SAM) is effective in improving developmental potential and weight gain in children aged under five years. A multicenter pretest-posttest study was conducted among 91 children aged under five with uncomplicated SAM in Pakistan. Study participants completed their eight weeks' therapy of ready-to-use therapeutic food according to the World Health Organization's (WHO) standard guidelines. The study outcome was the proportion of children with improved developmental potential in all domains in comparison with the pretreatment status and children gaining >15% of their baseline weight; mean weight-for-height/length z-score after completing eight weeks' therapy of ready-to-use therapeutic food. The Denver Development Screening Tool II was used for developmental screening. Significant changes ( < 0.05) were observed for developmental status milestones in terms of gross motor, fine motor, and personal/social milestones, as well as language and global development milestones. There was a strong positive correlation (r = 0.961) between initial weight and weight at the last visit ( < 0.001). Ready-to-use therapeutic food is effective in improving development potential as well as promoting weight gain in children aged under five with uncomplicated SAM if provided according to WHO guidelines.

From ECG signals to images: a transformation based approach for deep learning.

Provocative heart disease is related to ventricular arrhythmias (VA). Ventricular tachyarrhythmia is an irregular and fast heart rhythm that emerges from inappropriate electrical impulses in the ventricles of the heart. Different types of arrhythmias are associated with different patterns, which can be identified. An electrocardiogram (ECG) is the major analytical tool used to interpret and record ECG signals. ECG signals are nonlinear and difficult to interpret and analyze. We propose a new deep learning approach for the detection of VA. Initially, the ECG signals are transformed into images that have not been done before. Later, these images are normalized and utilized to train the AlexNet, VGG-16 and Inception-v3 deep learning models. Transfer learning is performed to train a model and extract the deep features from different output layers. After that, the features are fused by a concatenation approach, and the best features are selected using a heuristic entropy calculation approach. Finally, supervised learning classifiers are utilized for final feature classification. The results are evaluated on the MIT-BIH dataset and achieved an accuracy of 97.6% (using Cubic Support Vector Machine as a final stage classifier).

Depression as a Function of Social Support in Transgender and Cisgender Individuals with Sexually Transmitted Diseases.

This study focused on the relationships among social support, self-esteem, and depression in transgender and cisgender individuals suffering from an incurable or curable sexually transmitted disease. Data were collected from 210 participants with an STI using a semi-structured interview along with culturally adapted standardized instruments. Results indicated no differences between transgender and cisgender groups in depression, although there were large differences in social support and self-esteem. Preliminary regression analysis identified only STI type and duration of STI as significant predictors of depression. However, when moderating roles for both social support and self-esteem were tested, each added to the explained variance and, equally importantly, revealed the effects of both gender status and social support on depression. These findings not only demonstrate how the compound stressors of gender minority status and STI type affect depressive symptoms, but also reveal the critical role that social support can play in mitigating depressive symptoms in those with gender minority status. Findings are interpreted within the context of South/Central Asian cultures that have pre- and post-colonial traditions regarding the social role of non-binary individuals.
