Background/Objectives: Mild cognitive impairment (MCI) represents an intermediate stage between normal ageing and dementia, with a high annual progression rate. Despite its clinical relevance, no pharmacological treatment has been definitively approved for this condition; however, multiple pharmacological and non-pharmacological strategies have been investigated for their potential benefits. This systematic review assessed the effectiveness of both types of interventions in adults with MCI, aiming to identify effective strategies to preserve cognitive function. Methods: A systematic search (2017–2025) was conducted in PubMed, Scopus, ScienceDirect, SpringerLink, and WOS, following PRISMA guidelines. Randomised controlled trials and quasi-experimental studies involving adults aged ≥ 50 years with a diagnosis of MCI were included. Outcomes were evaluated in terms of cognitive, functional, behavioural, and quality-of-life improvements. Risk of bias was assessed using the RoB 2 and ROBINS-I tools. Results: Of 108,700 records screened, 40 studies were included. Non-pharmacological interventions, such as cognitive training (conventional, computerised, or virtual reality-based), consistently improved memory, attention, and executive functions (e.g., MoCA: +3.84 points; p < 0.001). Transcranial magnetic stimulation combined with physical exercise also demonstrated significant benefits (p = 0.025). Among pharmacological treatments, only vortioxetine and choline alfoscerate showed modest improvements; cholinesterase inhibitors had limited effects and frequent adverse events. Complementary therapies (yoga, probiotics, and acupuncture) yielded promising outcomes but require further validation. Conclusions: Non-pharmacological strategies, particularly cognitive training and physical exercise, emerge as the most effective and safe approaches for managing MCI. The inclusion of pharmacological interventions with preliminary evidence of benefit should be considered within a personalised, multimodal approach, while recognising the current absence of approved drug treatments for MCI. Further research is needed in underrepresented populations, such as those in Latin America.

Background: Corporal punishment (CP) remains a common disciplinary practice in many countries, despite evidence of its negative consequences for children’s development. Objective: This study examined the effectiveness of a culturally adapted intervention aimed at reducing parents’ use of CP. Method: Using a 12-month quasi-experimental longitudinal design, the study included an intervention group (n = 21) and a control group (n = 17). We administered standardized instruments at pretest and posttest to assess changes in parenting behavior, emotional regulation, and perceptions of child behavior. Artificial neural networks (ANNs) were used to model nonlinear relationships and classify group membership. Results: The intervention group showed significant improvements in parenting practices and emotion regulation. The ANN model classified participants with 74.6% accuracy. Key predictive variables included emotional suppression, physical punishment, and parental support and acceptance. Conclusions: These findings provide evidence for the effectiveness of the SERES program in reducing harmful parenting behaviors and promoting positive practices. Additionally, the use of AI models proved to be valuable for understanding complex behavioral changes, offering a promising approach for optimizing future interventions aimed at strengthening parenting and preventing family violence.

Background: Public transportation is one of the primary modes of mobility in urban environments, but it has also become a setting where sexual harassment frequently occurs. This situation not only compromises users’ safety but also has a significant impact on mental health. The objective of the study is to analyze the relationship between public transportation use, sexual harassment, and mental health through directed and undirected network analyses. Methods: This was an associative, basic, quantitative, and cross-sectional study. A total of 507 Peruvian adults (66.7% women) participated by completing a sociodemographic questionnaire and using psychological instruments. A Gaussian graphical model and a directed acyclic graph were used to estimate the networks, including assessments of precision and stability. Results: Results indicated that in the undirected network, public transportation use was associated with sexual harassment and anger. The central symptoms were generalized anxiety and depression. In the directed network, public transportation use influenced both sexual harassment and generalized anxiety. Furthermore, distress and sexual harassment emerged as conditionally dependent on multiple psychological factors. Conclusions: The findings suggest that implementing preventive and psychosocial intervention strategies in the context of public transportation may reduce experiences of sexual harassment and the manifestation of other mental health problems among adults in the general population, thereby promoting safer and healthier public environments.
