An increment in mental health problems related to social isolation strategies was evinced in several populations, however few investigations address this problem in students. This study aimed to analyze the relationship between insomnia, worry, coping strategies, and academic engagement in subjects pursuing a university degree in Argentina during the first month of compulsory social isolation against the COVID-19 pandemic. Self-report online questionnaires were administered to 584 participants: Insomnia Severity Index, Penn State Worry Questionnaire, Coping Responses Inventory, Utrecht Work Engagement Scale for Students. Demographic data was recorded. Statistics included bivariate and multivariate techniques. Prevalences of 45% for subthreshold insomnia, 23% for moderate insomnia, and 4% for severe insomnia were found. The severe insomnia group presented higher levels of worry and cognitive avoidance strategies. Insomnia was also associated with daytime concerns. The group without insomnia was more vigorous in their academic engagement. Being physically active was associated with lower sleep problems. Insomnia prevalence is high in socially isolated university students. Cognitive avoidance coping strategies are associated with worry, which leads to an alert state that makes sleep difficult. These findings should be taken into account by academic institutions to define their pedagogic strategies.

The Wisconsin Card Sorting Test (WCST) is a widely used neuropsychological assessment of executive functioning. The aim of this study was to provide norm values and analyze the psychometric properties of WCST in healthy Argentinian adults aged from 18 to 89 years old (N = 235). Descriptive statistics are reported as means, standard deviations and percentiles, with the effects of age, education and gender being investigated by ANOVA, and with the effect sizes being calculated. The psychometrics were studied using the WCST structure, reliability, convergent validity, and discriminant validity, and WCST norms adjusted for age and educational level are proposed. This instrument is a reliable and valid tool for the assessment of executive functions. However, as the age- and educational-related effects were demonstrated, these characteristics need to be considered before interpreting WCST scores. Regarding gender, no differences were found. Our results expand the geographical and sociocultural applicability of WCST.

Given that Argentinian public-sector workers are highly exposed to stressful conditions, and that the psychometric properties of the widely used Perceived Stress Scale (PSS) should be evaluated in different settings, this work aimed to compare the psychometric properties of the Latin American Spanish PSS-10 and PSS-4 and to identify the optimal scale for stress assessment. A sample of 535 participants was randomly divided into 2 groups to evaluate dimensionality by exploratory and confirmatory factor analyses. The reliability of both scales was also evaluated. Convergent validity was estimated using the Executive Complaints Questionnaire, the average variance extracted, and the composite reliability. Discriminant validity was based on the correlation with the Utrecht Work Engagement Scale and the phi-square correlation between the components. The factor analyses supported bidimensionality of the PSS-10 (stress and coping), which showed a better fit than the PSS-4. Moreover, the reliability of the PSS-10 was higher, whereas the PSS-4 did not achieve adequate values of internal consistency. The PSS-10 was also correlated significantly with all validation scales, and presented proper internal convergent and divergent validity. The PSS-10 is a reliable and structurally valid instrument to measure perceived stress and coping in a Latin American Spanish-speaking population with high work demands, and the findings of this study expand our knowledge on the geographical and sociocultural applicability of the PSS.

Breastfeeding is the most cost-effective intervention for reducing infant morbidity and mortality, offering benefits for infants and mothers. Despite extensive promotion, global adherence remains below 50 %, resulting in significant clinical, economic, and environmental impacts. Thus, this overview of reviews aims to synthesize barriers and facilitators of breastfeeding, analyze research trends, and identify gaps to guide future research. A comprehensive literature search was conducted, including systematic reviews that examine these factors. The search covered seven electronic data repositories. The methodological quality was assessed using the Risk of Bias in Systematic Reviews tool. Bibliometric analysis focused on identifying top journals, authors, and countries, assessing their impact, and exploring trends over time. Findings were classified and analyzed thematically through line-by-line coding, theme description, and analytical formulation. A total of 123 reviews were included, mostly of high quality and published in top journals. Key trends comprised a growing focus on psychosocial and cultural factors, increased representation from low- and middle-income countries, and improved methodological rigor. However, geographical representation remains biased towards high-income countries, and some breastfeeding outcomes need further exploration. Thematic analysis revealed four categories: Therapeutic and care interventions; Support networks and education; Maternal-infant health issues; and Societal and environmental context. In conclusion, this overview of reviews identifies barriers and facilitators of breastfeeding and emphasizes the need for more inclusive research and tailored support. Addressing gaps in evidence for enhancing healthcare systems and policies can improve breastfeeding practices and outcomes worldwide.
