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 Engageme nt 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.

Objective The 2019 coronavirus disease pandemic (COVID-19) required strict confinement measures that differentially impacted the individual's daily life. Thus, this work aimed to study postpartum women's mental health in Argentina during mandatory social isolation. Design A cross-sectional survey was conducted from May to July 2020, which included five validated questionnaires to assess postpartum depression (Postpartum Depression Screening Scale‐Short Form), insomnia (Insomnia Severity Index), memory complaints (Memory Complaint Scale), metacognition (Brief Metamemory and Metaconcentration Scale), and breastfeeding self-efficacy (Breastfeeding Self-Efficacy Scale-Short Form). Sociodemographic variables, social isolation characteristics, and breastfeeding practices were also collected. This study was conducted in accordance with the Declaration of Helsinki. Statistical analysis included zero-order correlations, multiple logistic regressions, and a set of structural equation models (SEM) to test direct and indirect effects. Goodness-of-fit indices were calculated for SEM. Setting Postpartum women were recruited from public hospitals, private health clinics, and online community recruitment in the Cordoba province (Argentina). Participants 305 postpartum women from Argentina. Measurements and findings 37% of women reported postpartum depression, 46% insomnia, 42% memory impairment, 60% low metaconcentration, 50% low metamemory, and 23% low breastfeeding efficacy. Also, significant associations were found demonstrating that social isolation promoted postpartum depression and insomnia were reciprocally related, which compromised female cognition and efficacy. This situation was aggravated in women during late postpartum, with previous children, and by low social support (e.g., family, health professionals), with non-exclusive breastfeeding being increased. Key conclusions This is the first study addressing postpartum women's mental status during social isolation in Argentina, which was a promoting factor for postpartum depression and insomnia that were reciprocally related. This situation was also aggravated by reproductive factors, such as late postpartum, multiparity, breastfeeding frequency, and non-exclusive breastfeeding. Additionally, breastfeeding self-efficacy depended on mental health status, and euthymia therefore favoured the practice of exclusive breastfeeding.

HJ-Biplot analysis is a multivariate graphic representation that collects data covariation structure between variables and individuals to represent them in a low-dimensional space with the highest quality in the same reference system. Consequently, it is a promising technique for evaluating dietary exposure to polyphenols and accurately characterizing female nutrition. Herein, we hypothesized that polyphenol intake defines specific clusters with dietary impacts, which can be assessed using HJ-Biplot, based on a cross-sectional study in Argentina. The study included 275 healthy postpartum women who provided information about their food frequency intake and other conditions, which were then used to evaluate polyphenolic intake using the Phenol-Explorer database. Outcomes were established using HJ-Biplot for clustering and ANOVA to compare their impact on diet quality indicators. Two HJ-Biplot models were run (for intakes >20 mg/d and 5∼20 mg/d, respectively) to identify three clusters per model with excellent statistical fitness to explain the data. Thus, specific polyphenolic clusters with potentially bioactive and safe compounds were defined despite significant interindividual variability. In fact, women with the lowest polyphenolic intake exhibited worse dietary quality, body fat, and physical activity. As a result, HJ-Biplot proved to be an effective technique for clustering women based on their dietary intake of these compounds. Furthermore, cluster membership improved the intake of antioxidants, water, fiber, and healthy fats. Additionally, women with formal jobs and a higher educational level showed a better diet. Dietary polyphenols are critical during postpartum because they exert beneficial effects on women and breastfed infants.

Introducción: Desde su fundación, la Facultad de Ciencias Médicas (FCM, UNC, Argentina) y sus miembros participaron en el diseño y la aplicación de políticas públicas eugénicas destinadas a evitar la despoblación y disminuir la mortalidad infantil. El presente trabajo describe dichas políticas desde la fundación de dicha institución hasta el inicio del proceso de Reforma Universitaria. Materiales y Métodos: Se realizó un análisis bibliográfico de bases de datos online y catálogos de bibliotecas para identificar textos referidos a políticas de puericultura y salud pública promovidas por la FCM en el período 1877 - 1918. Resultados: Se obtuvieron un total de 11 referencias bibliográficas: tres libros, dos artículos publicados en revistas científicas y seis Tesis para optar al título de Doctor en Medicina y Cirugía de la FCM. Discusión: Se evidencia en los textos analizados un gran interés en la caracterización de la mortalidad infantil en Córdoba y la promoción de la lactancia materna exclusiva. A ello se asocia la creación y administración de instituciones de salud de puericultura entre los que se destaca el Consultorio Protector de la Infancia. Conclusiones: La FCM, ligada a grupos políticos cordobeses, participó activamente en la difusión de los conceptos de puericultura (cuyas destinatarias eran principalmente las mujeres-madres de estratos socioeconómicos carenciados) y en la implementación de acciones tendientes al crecimiento poblacional y la inculcación de valores morales aceptados por sus académicos.
