Higher education institutions actively integrate information and communication technologies through learning management systems (LMS), which are crucial for online education. This study used data mining techniques to predict the autonomous scores of students in the online Law and Psychology programs at the Technical University of Manabi. The process involved data integration and selection of more than 16,000 records, preprocessing, transformation with RobustScaler, predictive modelling that included recursive feature elimination with cross-validation to select features (RFEcv), and hyperparameter fitting to achieve the best fit, and finally, evaluation of the models using metrics of root mean square error (RMSE), mean absolute error (MAE), and the coefficient of determination (R). The feature selection framework suggested by RFEcv contributed to the performance of the models. The variables analyzed focused on download rate, homework submission rate, test performance rate, median daily accesses, median days of access per month, observation of comments on teacher-reviewed assignments, length of final exam, and not requiring the supplemental exam. Hyperparameter adjustment improved the performance of the models after applying RFEcv. The models evaluated showed minimal differences in RMSE ([0.5411 .. 0.6025]). The gradient boosting model achieved the best performance of R = 0.6693, MAE = 0.4041 and RMSE = 0.5411 with the Law online program data, as with the Psychology online program data, with an R = 0.6418, MAE = 0.4232 and RMSE = 0.6025, while the combination of both data sets reflected the best performance with the extreme gradient boosting (XGBoost) model with the values of R = 0.6294, MAE = 0.4295 and RMSE = 0.5985. Future research and implementations could include autonomous score data through plugins and reports integrated into LMSs. This approach may provide indicators of interest for understanding and improving online learning from a personalized, real-time perspective.

Background: The COVID-19 pandemic has devastated economies and strained health care systems worldwide. Vaccination is crucial for outbreak control, but disparities persist between and within countries. In Taiwan, certain indigenous regions show lower vaccination rates, prompting comprehensive inquiries.

This study explored the impact of college students' disclosure of mental health problems on faculty well-being. Twenty-nine full- and part-time faculty who experienced a student disclosure related to mental health during their career were recruited from a mid-size, private liberal arts university. Semi-structured, in-depth interviews explored faculty experiences with student mental health disclosures and its impact on faculty well-being.

Objectives: To assess the time taken to diagnose cervical cancer in Brazil and identify associated sociodemographic and clinical factors in the period 2016-2020.
Methods: This was a cross-sectional study of cervical neoplasms diagnosed between 2016 and 2020, using data collected from the Hospital Cancer Registry. The logistic regression model was applied to calculate odds ratios (OR) and 95% confidence intervals (95%CI).

Objective: To assess the simultaneity of risk behaviors for chronic non-communicable diseases and their association with individual and contextual characteristics in Brazilian adolescents.
Methods: Cross-sectional study using data from the 2019 Brazilian National Health Survey. The simultaneity of factors of the consumption of ultra-processed foods, level of physical activity, smoking and alcohol use was analyzed, according to individual and contextual characteristics, estimating the odds ratios (OR) and respective 95% confidence intervals (95%CI) for fixed effects and variance and 95%CI for random effects, through multilevel polytomous logistic regression.
