Revisión narrativa del modelo de desarrollo positivo para adultos emergentes chilenos / A narrative review of the positive development model for Chilean emerging adults / Revisão narrativa do modelo de desenvolvimento positivo para adultos emergentes chilenos

Introducción: El desarrollo positivo es un estadio de ajuste psicosocial que acentúa las potencialidades y los recursos entre jóvenes y sus contextos próximos. En Australia, se desarrolló el primer modelo de desarrollo positivo para adultos emergentes, el cual consta de cinco componentes (competencia social, satisfacción con la vida, confianza y tolerancia con los otros, confianza hacia autoridades e instituciones, acción y compromiso cívico), pero no ha sido investigado en Chile. Objetivo: Analizar la evidencia disponible en la literatura científica sobre los cinco componentes del modelo de desarrollo positivo en adultos emergentes universitarios de Chile. Materiales y métodos: Revisión narrativa de la literatura publicada entre 2013 y 2023, en bases de datos Web of Science, Scopus, SciELO, Redalyc y Dialnet. Resultados: Se obtuvieron 83 artículos, de los cuales 53 cumplieron los requisitos de inclusión; en su mayor parte fueron estudios cuantitativos (81,13%) y en español (75,47%). Se evidenció una disparidad en la cantidad de estudios por temática; se encuentra mayor investigación en satisfacción con la vida y acción y compromiso cívico. Conclusiones: Existen brechas en la literatura científica chilena en el estudio del desarrollo positivo; además de que se discuten particularidades idiosincrásicas y desafíos asociados a la etapa de adultez emergente.

Introduction: Positive development is a stage of psychosocial adjustment that accentuates the potentials and resources of young people and their close contexts. The first positive development model for emerging adulthood was developed in Australia, which includes five components: social; life satisfaction; trust and tolerance of others; trust in the authorities and institutions; and action and civic engagement. However, this model has not been investigated in Chile. Objective: To analyze the evidence available in the scientific literature on the five components of the positive development model in emerging adults universities. Materials and methods: A narrative review of the literature published between 2013 and 2023 in the Web of Science, Scopus, SciELO, Redalyc, and Dialnet databases was conducted. Results: 83 articles were selected, of which 53 met the inclusion criteria; most of them were qualitative studies (81.13%) and in Spanish (75.47%). There is an evident disparity in terms of the number of studies and topics, e.g., there is more research on life satisfaction and civic action and commitment. Conclusions: There are gaps in the Chilean scientific literature in the study of positive development. In addition, idiosyncratic particularities and challenges associated with the stages of emerging adulthood are discussed.

Menstrual product choice and the extent of period poverty among young adult females: findings from a cross-sectional study in Kerala, India

Background: In Kerala state, India, while there is higher coverage of hygienic methods for menstrual protection among young women, empirical evidence on menstrual hygiene management is limited. This study aims to present menstrual hygiene product choices and the extent of period poverty among young adult females in Kerala.Methods: A cross-sectional study was conducted in Kerala using a web-based Google form. Data were collected on menstrual product usage, perceptions and attitudes towards menstruation, awareness and use of government initiatives for menstrual hygiene management, perspectives on better management, period poverty, and associated factors.Results: The mean age of respondents was 21.7 years (SD�0). Cultural beliefs hindered the choice of menstrual products. Period poverty was reported by 25.5% of respondents, with higher rates among younger, lower social category, and unemployed individuals. Lower income and negative attitudes towards menstruation were significantly associated with higher period poverty.Conclusions: There is a need for free menstrual products for the financially disadvantaged. Further research is necessary to gain a comprehensive understanding of period poverty in this community.

'Uma parte de mim sabia que isso aconteceria um dia': vivências de jovens com HIV/aids / 'A part of me knew this would happen one day': experiences of young people with HIV/ AIDS

RESUMO O objetivo deste estudo foi compreender as representações sociais de jovens que vivem com o HIV. Estudo qualitativo, ancorado na Teoria das Representações Sociais, realizado com 16 jovens em acompanhamento ambulatorial. Os dados foram coletados entre maio e outubro de 2022, por meio de entrevista semiestruturada. Para o tratamento dos dados, empregou-se a técnica de análise lexical, operacionalizada com o auxílio do software Iramuteq. A representação fortemente associada ao diagnóstico de HIV está relacionada ao desconhecimento, preconceito e aceitação, apresentando, também, elementos positivos como recomeço. Classes: Diagnóstico positivo para o HIV: o 'eu' de agora; HIV em face do desconhecimento e do estigma; e Relações interpessoais: diálogo, acolhimento e respeito necessários aos jovens. Compreendeu-se que as representações sociais dos jovens com HIV refletem a sua condição na sociedade. Os dados deste estudo mostram que existem formas distintas de vivenciar o HIV, muitas vezes representadas pela fragilidade, pela resignação, e outras, pelo fortalecimento. A fim de minimizar a vulnerabilidade do jovem à exposição ao HIV e aos riscos de conviver com o estigma e preconceito social, fazem-se necessárias a adoção de estratégias de conscientização da sociedade sobre a doença e a ampliação da divulgação de políticas públicas que abarcam essa temática.

ABSTRACT This study was aimed at understanding the social representations of young people living with HIV. This is a qualitative study, based on the Social Representations Theory, carried out with 16 young people in outpatient follow-up. Data were collected between May and October 2022, through semi-structured interviews. For data processing, the lexical analysis technique was used, operationalized with the aid of the IRAMUTEQ software. The representation strongly associated with the diagnosis of HIV is related to lack of knowledge, prejudice and acceptance, also presenting positive elements such as a new beginning. Classes: Positive diagnosis for HIV: the new 'me'; HIV in the face of ignorance and stigma; and Interpersonal relationships: dialogue, acceptance and respect necessary for young people. It was understood that the social representations of young people with HIV reflect their condition in society. The data show that there are different ways of experiencing HIV, often represented by fragility, resignation, and other times by strengthening. In order to minimize the vulnerability of young people to exposure to HIV and the risks of living with stigma and social prejudice, it is necessary to adopt strategies to raise awareness about the disease and to expand the dissemination of public policies that cover this topic.

Stroke associated with primary membranous nephropathy in a young adult: Case report / Evento cerebral isquémico asociado con nefropatía membranosa primaria en un adulto joven: reporte de caso

Abstract Introduction. Stroke in young individuals is becoming increasingly prevalent worldwide. Its causes can vary widely, so a thorough investigation by a multidisciplinary team is needed. Pinpointing the precise underlying pathology responsible for the stroke yields benefits for patients, particularly in recurrent events. Case presentation. A 38-year-old man presented to the emergency department with symptoms suggestive of stroke, including right hemiparesis, dysarthria, ataxic gait, and right central facial palsy. The brain magnetic resonance image revealed an ischemic lesion located in the left basal ganglia and near the corona radiata. Following an extensive workup, a diagnosis of nephrotic was reached. Histopathology and the exclusion of secondary causes confirmed primary membranous nephropathy as the underlying condition. The patient underwent treatment tailored to address the specific glomerulopathy, along with anticoagulation therapy and immunosuppression as per current guidelines. Subsequent assessments showed stabilization of renal function, resolution of the edema, and the absence of new thromboembolic events during follow-up. Conclusion. The nephrotic syndrome should be recognized as a potential underlying cause of stroke in young patients and, therefore, it should be included in the differential diagnosis during the evaluation of patients with coagulopathies. Nephrotic syndrome screening may be done by conducting a simple urinalysis readily available in most healthcare facilities. This underlines the importance of considering renal pathology in the assessment of stroke etiologies, especially when coagulation abnormalities are present.

Resumen Introducción. Los eventos cerebrovasculares en los jóvenes son un problema creciente en todo el mundo. Su etiología puede ser variada y requieren un trabajo riguroso de un equipo multidisciplinario. La identificación de la enfermedad específica que conduce al ictus tiene un impacto beneficioso en los pacientes, especialmente en aquellos con eventos recurrentes. Presentación del caso. Se presenta el caso de un hombre de 38 años que acudió al servicio de urgencias con hemiparesia derecha, disartria, ataxia y parálisis facial central derecha. La resonancia magnética cerebral reveló una lesión isquémica localizada en los ganglios basales izquierdos, cerca de la corona radiada. Después de un estudio exhaustivo, se estableció el diagnóstico de síndrome nefrótico. No obstante, al analizar las características histopatológicas y descartar otras causas secundarias, el diagnóstico final fue una nefropatía membranosa primaria. El paciente recibió tratamiento específico para su glomerulopatía, anticoagulación e inmunosupresión según las guías vigentes. Durante el seguimiento, se encontró estabilización de la función renal, el edema se resolvió y no se identificó ningún nuevo evento tromboembólico. Conclusión. El síndrome nefrótico debe considerarse entre las posibles causas del ictus en pacientes jóvenes y debería tenerse en cuenta en los estudios de coagulopatías. El tamizaje de esta enfermedad requiere únicamente un uroanálisis, el cual está disponible en la mayoría de los centros de atención de salud.

Resumen Objetivo: Determinar la relación entre el empoderamiento sexual y reproductivo, el conocimiento sobre derechos sexuales con la conducta sexual segura en jóvenes mexicanos. Materiales y métodos: El estudio fue descriptivo, correlacional y transversal. La muestra fue de 111 jóvenes de Chihuahua, México, los cuales se seleccionaron a conveniencia. La información se recolectó mediante una encuesta en línea. Resultados: Se encontró diferencia significativa del empoderamiento sexual y reproductivo entre hombres y mujeres (p < 0.001), los hombres presentaron puntajes más altos (Mdn= 92.39) comparados con las mujeres (Mdn= 79.34). No se encontró relación entre el empoderamiento sexual y reproductivo, el conocimiento sobre derechos sexuales con la conducta sexual segura de estos jóvenes. Conclusión: Los jóvenes presentaron un alto nivel de conocimiento sobre los derechos sexuales. Con relación al empoderamiento sexual y reproductivo, los hombres presentaron mayores puntuaciones que las mujeres. La conducta sexual segura fue menor que en otros estudios en poblaciones similares. Además, no se encontró relación entre el empoderamiento sexual y reproductivo, y el conocimiento sobre derechos sexuales con la conducta sexual segura en esta población, por lo que se enfatiza la necesidad de continuar estudiando estas variables debido a los escasos estudios en esta población.

Abstract Objective: To determine the relationship between sexual and reproductive empowerment, knowledge of sexual rights and safe sexual behavior in young Mexicans. Materials and methods: The study was descriptive, correlational and cross-sectional. The sample consisted of 111 young people from Chihuahua, Mexico, who were selected at convenience. The information was collected through an online survey. Results: A significant difference in sexual and reproductive empowerment was found between men and women (p < 0.001), with men presenting higher scores (Mdn= 92.39) compared to women (Mdn= 79.34). No relationship was found between sexual and reproductive empowerment, knowledge about sexual rights and safe sexual behavior of these young people. Conclusion: The young people presented a high level of knowledge about sexual rights. In relation to sexual and reproductive empowerment, males presented higher scores than females. Safe sexual behavior was lower than in other studies in similar populations. In addition, no relationship was found between sexual and reproductive empowerment and knowledge of sexual rights and safe sexual behavior in this population, which emphasizes the need to continue studying these variables due to the scarcity of studies in this population.

Representaciones sociales acerca de Instagram: Estudio cualitativo con adultos emergentes con diferente bienestar psicológico y autoestima corporal

Antecedentes existe una relación entre el uso de Instagram y diferentes influencias e interacciones con el bienestar y salud mental de este grupo etario. Objetivo Reconstruir las representaciones sociales acerca de la red social Instagram de adultos emergentes con diferentes niveles de bienestar psicológico y autoestima corporal. Método redes semánticas naturales y entrevistas semiestructuradas fueron aplicadas a N=12 adultos emergentes (19 - 27 años) divididos en dos grupos según sus niveles de autoestima corporal y bienestar psicológico. El análisis de datos estuvo basado en análisis de redes semánticas naturales y algunos procedimientos de codificación teórica. Resultados se muestra la presencia del concepto de "acoso" como núcleo central de la representación social de Instagram en el grupo con baja autoestima corporal y bajo bienestar psicológico, a diferencia del grupo con alta autoestima corporal y alto bienestar psicológico en donde el núcleo central fue "red social". Conclusiones en los grupos estudiados, se encontraron dos representaciones sociales diferentes respecto de Instagram. Estos resultados pueden ser relevantes para aportar a llenar el vacío de conocimiento sobre los significados subjetivos colectivos de los adultos emergentes, teniendo implicancias en la mejor comprensión de las diversas formas de relación que establecen con esta y otras redes sociales.

Background There is a relationship between the use of Instagram and various influences and interactions with the well-being and mental health of this age group. Objective To reconstruct the social representations of the Instagram social network among emerging adults with different levels of psychological well-being and body esteem. Method Natural semantic networks and semi-structured interviews were conducted with N=12 emerging adults (19 - 27 years old) divided into two groups based on their body self-esteem and psychological well-being levels. Data analysis relied on natural semantic network analysis and theoretical coding. Results The concept of "harassment" is revealed as the central core of the social representation of Instagram in the group with low body self-esteem and low psychological well-being, unlike the group with high body esteem and high psychological well-being where the central core was the "social network" itself. Conclusions Two different social representations of Instagram were found in the studied groups. These results could contribute to filling the knowledge gap about the collective subjective meanings of emerging adults, impacting the better understanding of the diverse relationships they establish with this and other social networks.

Infarto com Supra-ST em Adulto Jovem: Rara Apresentação de Mixoma Atrial Gigante / Acute ST-Elevation Myocardial Infarction in a Young Adult: Rare Presentation of Giant Atrial Myxoma

Resumo Neoplasias cardíacas são raras, tendo como principal representante o mixoma atrial (MA), que corresponde a cerca de metade de todos os casos. O MA tem incidência estimada entre 0.001% e 0.3% na população em geral, no entanto apenas aproximadamente 0,06% desses cursam com eventos embólicos coronarianos. Homem de 33 anos, tabagista, admitido com quadro de precordialgia intensa e irradiação para membro superior esquerdo com duração de uma hora. O eletrocardiograma evidenciou elevação de segmento ST nas derivações D2, D3 e aVF troponina sérica elevada, confirmando infarto com supra desnivelamento do segmento ST (IAMCSST). Foi realizada cineangiocoronariografia, a qual revelou oclusão em terço proximal de artéria coronária direita por trombo. Realizada tentativa de aspiração do trombo, sem sucesso, seguido por angioplastia primária com balão sem colocação de stent. Durante a investigação do quadro, paciente realizou ecocardiograma transtorácico o qual demonstrou massa homogênea de superfície regular, de 5.2 cm x 2.3 cm, aderida ao septo interatrial, com lobulações de características emboligênicas prolapsando para valva mitral e ventrículo esquerdo na diástole, compatível com MA. Foi realizada ressecção cirúrgica com paciente evoluindo assintomático, recebendo alta para seguimento ambulatorial. O caso relatado difere em idade e sexo do perfil epidemiológico típico sendo um dos poucos descritos com acometimento da parede inferior apresentando a artéria coronária direita como culpada. Este relato ratifica a importância do diagnóstico diferencial frente às apresentações de IAMCSST em jovens.

Abstract Cardiac tumors are rare entities, among which atrial myxoma (AM) stands as the most frequent, accounting for approximately half of all reported cases. The incidence of AM is estimated to range from 0.001% to 0.3% within the general population, yet only about 0.06% of these cases present with coronary embolic events. We report on a 33-year-old male smoker who experienced acute, severe precordial pain radiating to the left upper limb, lasting for one hour. The electrocardiographic evaluation demonstrated ST-segment elevation in leads D2, D3, and aVF, alongside significantly elevated serum troponin levels, confirming a diagnosis of ST-segment elevation myocardial infarction (STEMI). Subsequent coronary angiography revealed proximal occlusion of the right coronary artery due to thrombus. An initial attempt of thrombus aspiration was unsuccessful, followed by primary angioplasty with balloon inflation without stent placement. Further diagnostic exploration through transthoracic echocardiography identified a homogenous, smooth-surfaced mass measuring 5.2 cm x 2.3 cm attached to the interatrial septum. This mass, characterized by lobulations, prolapsed into the mitral valve and left ventricle during diastole, consistent with AM. Surgical resection of the mass was successfully performed, with the patient being discharged asymptomatic. In the reported case, the patient's profile, notably his age, and gender, diverges from the typical epidemiological characteristics associated with AM. This case adds to the limited number of reports where the inferior wall is affected by the right coronary artery being occluded. This report emphasizes the significance of differential diagnoses in younger patients presenting with STEMI.

Variaciones de alfa-amilasa salival relacionadas con edad, sexo e índice de masa corporal en estudiantes universitarios / Variations of salivary alpha-amylase related to age, sex and body mass index in university students

Objetivo. Determinar la presencia y dirección de la relación entre alfa-amilasa salival (AAs), edad, sexo e índice de masa corporal (IMC) en adultos jóvenes. Métodos. Este estudio transversal se desarrolló con una muestra de 50 estudiantes de odontología de 19 a 34 años de edad, 58% mujeres y 42% hombres. Se recogieron muestras de saliva entera sin estimular en la mañana (6:30-7:30 a.m.) y en la tarde (4:00-6:00 p.m.). Los valores de AAs se determinaron mediante método cinético y se expresaron como media ± desviación estándar. Se realizaron análisis descriptivo de datos, prueba de chi-cuadrado, prueba de correlación de Pearson y prueba t de muestras pareadas. Resultados. El IMC promedio fue de 23,85 ± 3,30 kg/m2, 66% de los participantes presentó peso normal (IMC ≤ 25 kg/m2). Los niveles de AAs por la tarde (282,74 ± 59,60 U/ml) fueron mayores a los de la mañana (190,84 ± 61,80 U/ml), (t = 16,51, p < 0,0001). Los hombres mostraron niveles de AAs más altos que las mujeres (p < 0,0001). La edad no mostró asociación con los niveles de AAs. Los valores de IMC y AAs presentaron una correlación positiva (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusión. El nivel de actividad de AAs se puede utilizar como posible biomarcador para evaluar el IMC en relación con el sexo, especialmente en los adultos jóvenes.

Objective. To determine the presence and direction of the relationship between salivary alpha-amylase (sAA), age, sex, and body mass index (BMI) in young adults. Methods. This cross-sectional study was developed with a sample of 50 dental students from 19 to 34 years of age, 58% women and 42% men. Unstimulated whole saliva samples were collected in the morning (6:30-7:30 a.m.) and in the afternoon (4:00-6:00 p.m.). sAA values were determined by the kinetic method and expressed as mean ± standard deviation. Descriptive data analysis, chi-square test, Pearson correlation test, and paired samples t-test were made. Results. Mean BMI was 23.85 ± 3.30 kg/m2, 66% of the participants presented normal weight (BMI ≤ 25 kg/m2). Levels of sAA in the afternoon (282.74 ± 59.60 U/ml) were higher than those in the morning (190.84 ± 61.80 U/ml), (t = 16.51, p < 0, 0001). Men showed higher levels of sAA than women (p < 0.0001). Age did not show an association with sAA levels. BMI and AAs values presented a positive correlation (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusions. AAs activity level can be used as a potential biomarker to assess BMI in relation to sex, especially in young adults.

Characteristics of resting energy expenditure and evaluation of prediction formulas in young men with different body mass indexes / 北京大学学报(医学版)

Objective:To compare the resting energy expenditure(REE)characteristics among young men with different body mass indexes(BMI).Methods:Thirty young men[average age was(26.93± 4.16)years]were enrolled in this study.They underwent resting metabolism tests in the Department of Sports Medicine of Peking University Third Hospital from December 2017 to June 2021.The resting meta-bolic rate(RMR)was measured by indirect calorimetry,the body composition was measured by bioresis-tance antibody component analyzer.The REE characteristics were analyzed,and 11 predictive equations were used to estimate RMR and compared with the measured value.The differences were analyzed by paired t-test and intra-class correlation coefficient(ICC).Results:The RMR of the overall 30 young men was(1 960.17±463.11)kcal/d(1 kcal=4.186 8 kJ).Including(1 744.33±249.62)kcal/d in those with normal BMI,which was significantly lower than that in those who were overweight or obese[(2 104.06±520.32)kcal/d,P＜0.01],but the weight-corrected RMR in those with normal BMI was significantly higher than that in those who were overweight or obese[(24.02±2.61)kcal/(kg·d)vs.(19.98±4.38)kcal/(kg·d),P＜0.01].The RMR was significantly and positively correlated with body weight,adiposity,lean body mass,body surface area,and extracellular fluid in the subjects with diffe-rent BMI(all P＜0.05).The predicted values of the 11 prediction equations were not in good agreement with the measured values(all ICC＜0.75),with relatively high agreement between the pre-dicted and measured values of the World Health Organization(WHO)equation in overweight obese young men(ICC=0.547,P＜0.01).Conclusion:There were significant differences in RMR among young men with different BMI,and the RMR after weight correction should be considered for those who were overweight or obese.The consistency between the predicted values of different prediction equations and the actual measured values of RMR was relatively poor,and it is recommended to accurately measure RMR by indirect calorimetry.For overweight or obese young men,the WHO prediction equation can be considered to calculate RMR,but it is necessary to establish an RMR prediction equation applicable to different BMI populations.

Aspects clinico-neurophysiologiques des troubles du sommeil dans une population d'adultes jeunes entre 18-35 ans / Clinical-neurophysiological aspects of sleep disorders in a population of young adults aged 18-35 years

Contexte et objectifs : L'accès aux tests neurophysiologiques pour le diagnostic des Troubles du Sommeil (TS) est très limité dans les pays d'Afrique subsaharienne. La présente étude avait pour objectif de déterminer les caractéristiques épidémiologiques, cliniques et neurophysiologiques des (TS) dans un groupe de jeunes adultes. Méthodes : Il s'est agi d'une étude descriptive d'une série de cas, réalisée au centre de Médecine du sommeil et des maladies respiratoires de l'hôpital de la Croix-Rousse de Lyon du 1er janvier au 31 mars 2019. Les patients hospitalisés pendant cette période pour l'exploration d'un (TS) ont été sélectionnés. Etaient éligibles ceux dont l'âge était compris entre 18 et 35 ans, des deux sexes, ayant renseigné un questionnaire et ayant bénéficié au minimum d'une polysomnographie (PSG). Résultats : Quatre-vingt-onze patients étaient examinés. Les femmes étaient les plus affectées (59,3 %). Leur âge moyen était de 26,6 ± 5 ans. La PSG a incriminé le Syndrome d'Apnée Hypopnée Obstructive du sommeil (SAHOS) comme étiologie principale (66 %). Pour les patients sans SAHOS, 38,7 % avaient une PSG normale et la PSG avec d'autres tests de sommeil ont objectivé, pour le reste (61,3 %), d'autres types de (TS). La dépression (50,7 %) et la fatigue chronique (84,6 %) étaient très fréquentes. L'indice d'efficacité du sommeil était faible pour 70 % des patients avec SAHOS. Il y avait un déséquilibre de la durée des stades du sommeil, augmentée pour le sommeil lent léger et diminuée pour le sommeil lent profond dans la population avec SAHOS, tandis que la durée du sommeil paradoxal chez ceux sans SAHOS était augmentée. Conclusion Le SAHOS est fréquent dans cette formation hospitalière, avec des répercussions significatives à type de dépression et de fatigue chronique. Il est important que des mesures rendant accessible l'usage des tests d'exploration du sommeil particulièrement en Afrique au sud du Sahara, soient mises en place pour diagnostiquer ces troubles

Context and objective. Access to neurophysiological tests for diagnostic of sleep disorders (SD) is very limited in Sub-Saharan Africa countries. The objective was to determine the epidemiological, clinical and neurophysiological characteristics of SD in a young adult group. Methods. This was a descriptive serial cases study carried out at the Sleep Medicine and Respiratory Diseases Center of the CroixRousse hospital of Lyon between January 1st and March 31th, 2019. Patients hospitalized during this period with tests for SD were selected. Eligible were those aged between 18 and 35 years, both sexes, who completed a questionnaire and who received at least a polysomnography (PSG). Results. Ninety-one patients were involved. Women remained the most affected (59.3%). Mean age was 26.6±5 years. PSG incriminated obstructive sleep apnea (OSA) syndrome as the primary etiology (66%). For patients without OSA, 38.7% had normal PSG. For the remaining 61.3% of patients, other types of SD were found using PSG with various sleep tests. Depression (50.7%) was an important comorbidity, and chronic fatigue (84.6%) was the most frequent complaint. Sleep efficiency index was low for 70% of sleep apnea patients. There was an imbalance in the duration of sleep stages, with an increase in light slow-wave sleep in the OSA population and a decrease in their deep slow-wave sleep, while REM sleep duration in patients without OSA was increased. Conclusion: OSA was the primary etiology in our study, with significant repercussions like depression and chronic fatigue. Public health measures such as increasing access to the use of sleep exploration tests, especially in subSaharan Africa, should be put in place for the diagnosis of these sleep disorders and their consequences

O papel mediador da dependência de mídia social e da qualidade do sono na associação entre tempo de uso de mídia social e sintomas depressivos em universitários / The mediating role of social media addiction and sleep quality in the association between social media usage and depressive symptoms in university students / El papel mediador de la adicción a las redes sociales y la calidad del sueño en la asociación entre el tiempo de uso de las redes sociales y los síntomas depresivos en estudiantes universitarios

Resumo: O aumento do uso de mídias sociais e sua associação com sintomas depressivos, especialmente em jovens adultos, tem gerado a necessidade do entendimento de como ocorre tal associação para subsidiar políticas de redução de danos e agravos. Nesse sentido, este estudo objetivou verificar o efeito mediador da dependência de mídias sociais e da qualidade do sono na associação entre o tempo de uso de mídias sociais e sintomas depressivos em universitários brasileiros. Trata-se de um estudo transversal, realizado com 2.823 universitários, que forneceram informações referentes ao tempo de uso de mídias sociais, à dependência de mídias sociais, aos sintomas depressivos e à qualidade do sono. A análise de mediação, ajustada por fatores de confusão, foi realizada por meio do software PROCESS para SPSS, para obtenção do efeito total (c), direto (c') e indiretos (EI1, EI2 e EI3). Os resultados identificaram associação entre o tempo de uso de mídias sociais e os sintomas depressivos, mediada pela dependência de mídias sociais (EI1 = 20%) e pela qualidade do sono (EI1 = 40%). Os resultados permitem ampliar o conhecimento acerca dos mecanismos que influenciam mutuamente a relação entre o tempo de uso de mídias sociais e os sintomas depressivos, auxiliando na adoção de estratégias de redução de danos decorrentes do uso excessivo de mídias sociais.

Abstract: Increase in time spent on social media and its association with depressive symptoms, especially among young adults, has generated the need to understand how this association occurs in order to support the development of policies to reduce harm and complications. In view of this fact, this study aimed to assess the mediating effect of social media addiction and sleep quality on the association between time spent on social media and depressive symptoms in Brazilian university students. This is a cross-sectional study conducted with 2,823 university students, who provided information regarding time spent on social media, social media addiction, depressive symptoms and sleep quality. The mediation analysis, adjusted for confounding factors, was performed using the PROCESS macro for SPSS to obtain the total (c), direct (c'), and indirect effects (EI1, EI2, and EI3). The results identified an association between time spent on social media and depressive symptoms, mediated by social media addiction (EI1 = 20%) and sleep quality (EI1 = 40%). These findings help expand knowledge about the mechanisms that mutually influence the relationship between time spent on social media and depressive symptoms, supporting the adoption of strategies to reduce harm resulting from excessive social media use.

Resumen: El aumento del uso de las redes sociales y su asociación con síntomas depresivos, especialmente en adultos jóvenes, ha generado la necesidad de comprender cómo se produce esta asociación como una forma de apoyar las políticas de reducción de daños y afecciones. En ese sentido, el presente estudio tuvo como objetivo verificar el efecto mediador de la adicción a las redes sociales y de la calidad del sueño en la asociación entre el tiempo de uso de las redes sociales y los síntomas depresivos en estudiantes universitarios brasileños. Se trata de un estudio transversal, realizado con 2.823 estudiantes universitarios, quienes brindaron información respecto al tiempo de uso de las redes sociales, adicción a las redes sociales, síntomas depresivos y calidad del sueño. El análisis de mediación, ajustado por factores de confusión, se realizó por medio del software PROCESS para SPSS, para obtener el efecto total (c), directo (c') e indirectos (EI1, EI2 y EI3). Los resultados identificaron una asociación entre el tiempo de uso de las redes sociales y los síntomas depresivos, mediada por adicción a las redes sociales (EI1 = 20%) y la calidad del sueño (EI1 = 40%). Los resultados permiten ampliar el conocimiento acerca de los mecanismos que influyen mutuamente en la relación entre tiempo de uso de las redes sociales y los síntomas depresivos, ayudando a adoptar estrategias para reducir los daños resultantes del uso excesivo de las redes sociales.

Abstract Objective To describe acute kidney injury prevalence in young adults diagnosed with COVID-19 admitted to the Intensive Care Unit. Methods This is a retrospective, quantitative and analytical study. The sample consisted of young adults (20 to 40 years old) admitted to Intensive Care Units, diagnosed with SARS-CoV-2 infection between March and December 2020. Data were obtained through electronic medical records, and kidney injury acute was defined by the creatinine value, according to the Kidney Disease Improving Global Outcomes guidelines criteria. Statistical significance was p≤0.05. Results A total of 58 young adults were hospitalized, 63.8% of whom were male. Hypertension was present in 39.6%, obesity in 18.9%, and diabetes mellitus in 8.6%. Acute kidney injury was identified in 55.1%, with stage 3 predominating in 43.1% of them. In these patients, the use of mechanical ventilation and vasoactive drugs was significant in 92% as well as respiratory organ dysfunction (80%), followed by renal organ dysfunction (76%). Risk factors such as kidney transplantation or chronic kidney disease and obesity increased by 12.3 and 9.0 times, respectively, the chances of developing acute kidney injury. Conclusion This study demonstrated a high kidney injury prevalence in young adults and its association with previous comorbidities. Obesity, kidney transplantation and chronic kidney disease increased the chance of young adults to develop acute kidney injury, resulting in outcomes in favor of morbidity and mortality.

A randomized controlled trial of a dissonance‐based eating disorder prevention intervention for body-dissatisfied Brazilian men: results from a 1-year follow-up

Objective: To test the efficacy of a dissonance-based (DB) intervention in targeting risk factors for eating disorders (EDs) and predisposing factors for muscle dysmorphia (MD) symptoms in body-dissatisfied Brazilian men over 1 year of follow-up and evaluate whether reductions in body-ideal internalization would mediate the intervention's impact on ED and MD symptoms. Methods: Participants were randomized to a two-session DB intervention (n=89) or assessment-only control (AOC) (n=91), and completed validated measures assessing body-ideal internalization, body dissatisfaction, ED, and MD symptoms at baseline, post-intervention, 1-month, 6-month, and 1-year follow-ups. Results: The DB condition showed significantly greater reductions in MD symptoms and body dissatisfaction compared with the AOC group over a 1-year follow-up, while significant differences were not observed for body-ideal internalization and ED symptoms. Changes in body-ideal internalization from baseline to 1-month follow-up completely mediated the relationship between condition and the changes observed in both ED and MD symptoms. Conclusion: These results provide further evidence of the efficacy of the tested intervention through 1-year follow-up in reducing body dissatisfaction and MD symptoms, but no such result was observed for body-ideal internalization and EDs. Our findings provide support for theoretical models of eating pathology and MD symptoms in Brazilian men. Clinical Trial Registration: Brazilian Registry of Clinical Trials (ReBEC): RBR-27dc264.

Lexical quality measures in the assessment of reading proficiency in Brazilian university students / Medidas de qualidade lexical na avaliação da proficiência de leitura em alunos universitários brasileiros

ABSTRACT Purpose: to assess the reading ability of university students using tasks to measure Lexical Quality (LQ) and evaluate the influence of socioeconomic status (SES) on both the reading performance and the components of Lexical Quality (LQ). Methods: 44 students from two federal universities took online linguistic tests, 19 from the Federal University of the Great ABC Region (UFABC) and 25 from the Federal University of Ceará (UFC), Brazil. Two-ranked Mann-Whitney (Wilcoxon rank-sum test) and Pearson's Correlation tests at p<0,05 were applied to analyze the data. Results: high and medium correlations were obtained among the different components of LQ, such as vocabulary and spelling recognition. In addition, significant differences were found between the performances of the two universities' students and their distinct socioeconomic levels. Conclusion: shorter reading times were correlated to higher accuracy in the Test of Word Reading Efficiency for Adults. The number of correct answers in the homonym test was correlated to the higher accuracy of the Test of Word Reading Efficiency for Adults, and both were correlated to the reaction time measures of these tests. The influence of socioeconomic status on reading performance and Lexical Quality components tasks was also found.

RESUMO Objetivos: comparar o desempenho de alunos universitários brasileiros a partir de tarefas com habilidades de qualidade lexical e avaliar a influência do nível socioeconômico no desempenho da leitura e nos componentes que formam a qualidade lexical. Métodos: testes linguísticos on-line foram aplicados em 44 estudantes de duas universidades federais, sendo 19 da Universidade Federal do ABC e 25 da Universidade Federal do Ceará. Para análise foram utilizados os testes Mann-Whitney (Wilcoxon rank-sum test) de duas vias e a Correlação de Pearson com p<0,05. Resultados: foram obtidas correlações altas e médias entre os diferentes componentes da qualidade lexical, tais como vocabulário e reconhecimento ortográfico, além de terem sido encontradas diferenças significativas entre o desempenho dos alunos das duas universidades e de diferentes níveis socioeconômicos. Conclusão: menor tempo de leitura apresentou correlação com maior quantidade de acertos na leitura de palavras em voz alta, a quantidade de acertos no teste de homônimos correlacionou-se a quantidade de acertos no teste de leitura de palavras em voz alta e ambas correlacionaram-se com o tempo de resposta destes testes. Houve, também, influência do nível socioeconômico no desempenho da leitura e nos componentes que formam a qualidade lexical.

Eating locations and occasions by energy and nutrients food sources among adolescents and young adults / Locais e ocasiões das refeições e alimentos fontes energia e nutrientes entre adolescentes e jovens adultos

ABSTRACT Objective This study aimed to estimate the daily energy intake and overconsumed nutrients for adolescents and young adults concerning public health based on the food source, eating location, and occasion. Methods This study constituted a cross-sectional analysis of the 2015 Health Survey of São Paulo focusing on Nutrition with 707 adolescents (n=554, 12-19 years) and young adults (n=153, 20-30 years). Dietary intake was measured using 24 h recall, and energy, added sugars, sodium, and saturated food sources were calculated. Foods were classified using the "What We Eat in America?" classification system. Eating locations were divided into two categories-at home and away from home-for each main meal (breakfast, lunch, and dinner). Other sociodemographic and weight status variables were included. Descriptive statistics, the Wald test, and proportion rates were applied for analysis. Results Most meals were consumed at home by 80.5% of adolescents and 66.4% of young adults. Young adults consumed more daily calories and saturated fats than adolescents. Both adolescents and young adults consumed equal daily saturated fatty acids, sodium, and added sugars away from home at dinner. Food consumed at home was consumed both at home and away from home, with the main exception of dinner, which consisted of mainly processed foods rich in saturated fatty acids, sodium, and added sugars consumed away from home. Conclusion Adolescents and young adults had meals higher in fat, sugar and sodium away from home than those who ate at home when eaten at dinner. Public health policies and behavioral change strategies should be considered independently of where their meals are consumed but with particular attention to eating occasions.

RESUMO Objetivo Este estudo teve como objetivo estimar a ingestão diária de energia e nutrientes de maior preocupação em saúde pública entre adolescentes e jovens adultos, com base nos alimentos fonte, local e tipo de refeição. Métodos Este estudo é de delineamento transversal que utilizou dados do Inquérito de Saúde do Município de São Paulo 2015 (ISA-Capital) focado na Nutrição. A amostra compreendeu 707 adolescentes (n=554, 12-19 anos) e adultos jovens (n=153, 20-30 anos). O consumo alimentar foi avaliado por meio do Recordatório Alimentar de 24h (R24H) e a calculou-se as fontes de energia, açúcar de adição, sódio, e gordura saturada. Os alimentos foram classificados pelo sistema de classificação "What We Eat in America?" Os locais de alimentação foram divididos em duas categorias - "em casa" e "fora de casa" - para cada refeição principal (café da manhã, almoço e jantar). Outras variáveis sociodemográficas e antropométricas foram incluídas. Estatísticas descritivas, teste de Wald e proporções foram aplicadas para análise. Resultados A maioria das refeições era consumida em casa por 80,5% dos adolescentes e 66,4% dos adultos jovens. Os adultos jovens consumiam mais calorias diárias e gorduras saturadas do que os adolescentes. Tanto adolescentes, quanto adultos jovens, consumiam majoritariamente ácidos graxos saturados, sódio e, açúcares de adição fora de casa, no jantar. Os alimentos consumidos em casa eram consumidos tanto em casa quanto fora de casa, com a principal exceção do jantar, que consistia, principalmente, em alimentos processados ricos em ácidos graxos saturados, sódio e açúcares de adição consumidos fora de casa. Conclusão Adolescentes e adultos jovens apresentaram refeições mais ricas em gordura, açúcares e sódio fora de casa em comparação com aqueles que consomem em casa quando consumidos no jantar. Políticas de saúde pública e estratégias de mudança de comportamento devem ser consideradas independentemente do local onde suas refeições são consumidas, mas com especial atenção ao tipo de refeição.

Prevalence of depressive symptoms among young adults in Brazil: Results of the 2013 and 2019 editions of the National Health Survey / Prevalência de sintomas depressivos entre adultos jovens no Brasil: resultados da Pesquisa Nacional de Saúde 2013 e 2019

ABSTRACT Objective: To estimate the prevalence of depressive symptoms in the population aged 18 to 24, according to socioeconomic and demographic aspects in Brazil, comparing its evolution between 2013 and 2019. Methods: Cross-sectional study carried out with secondary data obtained from National Health Survey 2013 and 2019. It were included 7,823 young adulthood (aged 18 to 24) from 2013 and 8,047 from 2019. The instrument used to assess depression was the Patient Health Questionnaire-9 (PHQ-9). All estimates included population weights and complex sampling. Results: The prevalence of depression almost doubled: 10.9% (95%CI 9.6-12.2) in 2019, compared to 5.6% (95%CI 4.8-6.4) in 2013, an absolute difference of 5.3% (4.5-6.0) greater. Women were the most affected in both surveys, with an increase between 2013 (8.3%; 95%CI 6.9-9.6) and 2019 (15.6%; 95%CI 13.5-17.6) higher than that of men (2013: 2.9%; 95%CI 2.0-3.8 and 2019: 6.2%; 95%CI 4.7-7.7). In both sexes, the pattern of increase was greater for the groups aged 18 to 20, not participating in religious activities, who were at the lowest levels of education and income, who lived with two or three or more people, who lived in the Northeast, Southeast, capitals and metropolitan areas of the country. Conclusion: There was a significant increase in the prevalence of depressive symptoms over the six years between the two surveys. However, this increase did not occur homogeneously among the characteristics analyzed, indicating population groups and locations in Brazil where the presence of these symptoms increased most in the period.

RESUMO Objetivo: Estimar a prevalência de sintomas depressivos na população de 18 a 24 anos, segundo aspectos socioeconômicos e demográficos no Brasil, comparando sua evolução entre os anos de 2013 e 2019. Métodos: Estudo transversal realizado com dados secundários da Pesquisa Nacional de Saúde 2013 e 2019. Foram incluídos 7.823 adultos jovens (18 a 24 anos) de 2013 e 8.047 de 2019. O instrumento utilizado para avaliar a depressão foi o Patient Health Questionnaire-9 (PHQ-9). Todas as estimativas incluíram os pesos da população e a amostragem complexa. Resultados: A prevalência de sintomas depressivos quase dobrou: 10,9% (IC95% 9,6-12,2) em 2019, ante os 5,6% (IC95% 4,8-6,4) em 2013; uma diferença absoluta de 5,3% (4,5-6,0) maior. As mulheres foram as mais afetadas em ambos os inquéritos, com aumento entre 2013 (8,3%; IC95% 6,9-9,6) e 2019 (15,6%; IC95% 13,5-17,6) superior aos dos homens (2013: 2,9%; IC95% 2,0-3,8 e 2019: 6,2%; IC95% 4,7-7,7). Em ambos os sexos, o padrão de aumento foi maior para os grupos de 18 a 20 anos; não participantes de atividades religiosas; que estavam nos mais baixos níveis de escolaridade e renda; que residiam com duas ou mais pessoas; e que residiam nas regiões Nordeste, Sudeste, capitais e áreas metropolitanas do país. Conclusão: Verificou-se aumento estatisticamente significante da prevalência de sintomas depressivos ao longo dos 6 anos dos inquéritos. Esse aumento não ocorreu de modo homogêneo entre as características analisadas, indicando os grupos populacionais e localidades do Brasil em que mais cresceu a presença desses sintomas no período.
