Abstract

Elementary school children are in a critical period of growth and development. Proper nutritional intake, especially from vegetables and fruit, is very important to support their health, strengthen the immune system, and prevent disease. Increasing knowledge about the benefits of consuming fruit and vegetables needs to be done in order to prevent various diseases related to nutrition and optimize growth and development. The method used was health education for 31 Mis students. This activity begins with distributing pre-test questionnaires, counseling and ends with distributing post-test questionnaires. The results of this activity show that the outreach activities related to the benefits of consuming fruit and vegetables were carried out well and almost 70% experienced an increase in knowledge. In conclusion, there was an increase in knowledge after counseling was carried out through presentations and screening of educational videos.

Abstract

Neprilysin (NEP) is a zinc-dependent metallopeptidase, considered a key therapeutic target in heart failure management. Efficient identification of potent NEP inhibitors remains a challenge in drug discovery. The aim of this study was to develop a quantitative structure–activity relationship (QSAR) model using 2D Mordred molecular descriptors and Random Forest algorithms to predict the inhibitory potency (pIC50) of drug candidates. A curated dataset of compounds with experimentally determined IC₅₀ values (in nM) against NEP was preprocessed and converted to pIC50. Mordred was used to calculate 2D molecular descriptors, and descriptors with missing values were excluded. The dataset was split into training, internal validation, and external test sets. A Random Forest regression model was trained using 500 estimators, and model performance was evaluated using R2, root mean square error (RMSE), mean absolute error (MAE), and concordance correlation coefficient (CCC), while a binary classification model was also constructed. Feature importance, residual analysis, and chemical space visualization were conducted to assess model interpretability and reliability. The regression model demonstrated moderate to strong predictive performance, with R2 of 0.286, RMSE of 0.949, MAE of 0.723, and CCC of 0.532 in the internal validation. External validation showed improved generalization, with R2=0.659, RMSE=0.858, MAE=0.630, and CCC=0.763. Binary classification revealed an accuracy of 0.953, precision of 1.000, recall of 0.943, and an F1-score of 0.971, indicating strong discriminative ability in classifying inhibitory versus non-inhibitory compounds. Top contributing descriptors included ATSC2p (feature importance=0.0505), GATS2p (0.0408), and SaasC (0.0317). Principal component analysis (PCA) and Williams plots confirmed that test compounds lie within the model’s applicability domain, with no major outliers in leverage or residual distribution. The developed Random Forest-based QSAR model demonstrates strong predictive power and interpretability for identifying NEP inhibitors. This study provides a valuable tool for virtual screening and highlights the relevance of 2D structural features in governing NEP inhibitory activity. It is the first dedicated QSAR analysis of neprilysin inhibition using Mordred descriptors with rigorous internal and external validation.

Abstract

DHF is a health problem in tropical climates. This disease can disrupt the function of capillary blood vessels and the blood clotting system, thus increasing the risk of bleeding in sufferers. This study design was a case-control study with 31 cases and 31 controls, totaling 62 respondents. The sampling technique was total sampling, with data collected through questionnaires over 27 days. The results of the univariate analysis showed that most respondents sometimes empty landfills (43.5%), do not cover them properly (58.1%), and do not recycle used items (91.9%). In addition, 79% hang clothes indoors, 69.4% use mosquito repellent, and 79% consider the role of mosquito larvae control teams to be inadequate. Bivariate analysis showed that the behavior of draining (p = 0.001; OR = 13.3) and covering water reservoirs (p = 0.033; OR = 2.6) were significantly associated with the incidence of dengue fever, while recycling used goods (p = 0.162; OR = 0.225), hanging clothes (p = 0.755; OR = 1.215), the use of mosquito repellent (p = 0.409; OR = 1.581), and the role of jumantik (p = 0.119; OR = 2.761) did not show a statistical relationship. Community behavior in implementing 3M Plus plays a role in the incidence of DMF, especially the habit of not draining landfills regularly. Therefore, cross-sectoral cooperation and continuous education are needed between the government, health workers, and the community through mosquito nest eradication activities and routine counseling, so that compliance can be increased and the incidence of DMF can be suppressed.
