RESUMO

OBJECTIVE: To examine the association between social capital and household food insecurity among US families with newborns. STUDY DESIGN: This cross-sectional analysis used enrollment data from 881 newborn-caregiver dyads at 6 geographically-diverse US academic sites enrolled in the Greenlight Plus Trial, a comparative effectiveness trial to prevent childhood obesity. Ordinal proportional-odds models were used to characterize the associations of 2 self-reported measures of social capital: (1) caregiver social support and (2) neighborhood social cohesion, with household food insecurity after controlling for sociodemographic characteristics. RESULTS: Among 881 newborn-caregiver dyads (49% Hispanic, 23% non-Hispanic White, 17% non-Hispanic Black; 49% with annual household income <$50 000), food security was high for 75%, marginal for 9%, low for 11% and very low for 4%. In covariate-adjusted analyses, caregivers with a low social support score of 18 had 5 times the odds (aOR = 5.03 95% CI = 3.28-7.74) of greater food insecurity compared with caregivers with a high social support score of 30. Caregivers with a low neighborhood social cohesion score of 10 had nearly 3 times the odds (aOR = 2.87 95% CI 1.61-5.11) of greater food insecurity compared with caregivers with a high neighborhood social cohesion score of 20. These associations remained robust when both social capital measures were included in one model. CONCLUSIONS: Caregiver social support and neighborhood social cohesion each appear to be inversely associated with food insecurity among US families with newborns. Longitudinal research is needed to determine the directionality of these relationships and whether improving social capital for families with young children reduces household food insecurity.

RESUMO

Adolescence and emerging adulthood are two life stages marked by notable cognitive and socioemotional changes. During both periods, friendships play an increasingly significant role and can significantly impact individuals positively or negatively. Despite the evolving nature of these relationships, parents remain crucial to the development of both adolescents and emerging adults, playing a key role in their well-being. This study aimed to investigate the mediating role of attachment to friends in the relationship between parental attachment and the well-being of Chilean adolescents and emerging adults. In a cross-sectional correlational study, 363 adolescents (48.2% female) aged 14 to 17 years (M = 15.33, SD = 0.95) and 199 emerging adults (67.8% female) aged 18 to 29 years (M = 22.42, SD = 2.53) completed the Inventory of Parent and Peer Attachment and the Pemberton Happiness Index Scale to assess general, eudaimonic, hedonic, and social well-being. Results of path analyses indicated that, for both adolescents and emerging adults, a more secure attachment to parents was directly associated with higher scores in all well-being dimensions. Additionally, more secure parental attachment was indirectly associated with better eudaimonic and social well-being through a more secure attachment to friends. These findings suggest that enhancing parental attachment could be a valuable focus in clinical interventions aimed at improving overall well-being in adolescents and emerging adults.

RESUMO

INTRODUCTION AND AIM OF THE STUDY: This contribution explores the many pathologies that plague the existence of the renowned Mexican artist Frida Kahlo (1907-1954) and the impact they had on her character. METHODOLOGY AND RESULTS: Moving from a mere pathobiographical reassessment, this note, through historico-medical research, highlights the patient-physician relationship that the painter developed with Dr. Leo Eloesser (1881-1976) and underlines the role this form of friendship may play in patients' wellbeing. CONCLUSION: The special friendship between the artist/patient, Frida Kahlo, and her physician, Dr. Eloesser, shows that medicine is not just the sum of diagnoses and therapies but a much more dynamic and complex process involving trust and humane qualities.

RESUMO

Objective: The current study aimed to develop and validate of companions' satisfaction questionnaire of patients hospitalized in ICUs. Methods: This is a methodological study that was performed in three phases: In the first phase, the concept of companion's satisfaction of patients hospitalized in ICUs was defined through qualitative content analysis method. In the second phase, early items of questionnaire were generated based on findings of the first phase. In the third and final phase, validation of the questionnaire was evaluated using face, content and construct validity as well as reliability. Results: In exploratory factor analysis, three subscales including: satisfaction with nursing staff communication (5 items), satisfaction with nursing care (12 items), and satisfaction with decision making (5 items) were extracted by Eigen value above one and factor load above 0.5. Internal consistency and stability of the developed questionnaire confirmed with 0.94 and 0.95 respectively that indicated acceptable reliability. Conclusion: The 22-item developed questionnaire is valid and reliable for measurement of levels of companion's satisfaction of Iranian patients hospitalized in ICUs.

RESUMO

Both parasympathetic nervous system regulation and receipt of social support from close relationships contribute to prosocial development, although few studies have examined their combined influences in adolescence and particularly within racially and ethnically minoritized populations. In this longitudinal study of 229 U.S. Mexican-origin adolescents (48% female-identifying), youths reported on receipt of social support from family and friends from 10 to 16 years, had their baseline respiratory sinus arrhythmia (RSA) measured at 17 years, reported their prosocial behavior and completed the Mind in the Eyes test to assess cognitive empathy at 17 and 19 years, and reported their prosocial civic behavior (i.e., community activity) at 19 years. Family social support predicted prosocial behavior at 17 years, and friend social support predicted prosocial civic behavior at 19 years. Compared to youths with lower or higher baseline RSA, youths with moderate RSA reported more prosocial civic behavior, had greater cognitive empathy, and tended to report more general prosocial behavior at 19 years. The quadratic association between baseline RSA and cognitive empathy was stronger for youths with greater family social support. These findings are the first to extend the evidence that moderate baseline parasympathetic nervous system activity supports prosocial development into late adolescence and with the U.S. Mexican-origin community, and these findings address calls for more integrative biopsychosocial studies of prosociality.

RESUMO

BACKGROUND: Peers constitute an important developmental context for adolescent academic behaviour providing support and resources to either promote or discourage attitudes and behaviours that contribute to school success. When looking for academic help, students may prefer specific partners based on their social goals regarding academic performance. AIMS: Based on the social goals for wanting to achieve academically (e.g., studying to be with friends, increasing/maintaining their own social status), we examine the extent to which adolescents' selection of preferred academic partners (with whom they would like to study) is driven by peers' academic performance, prosocial behaviour and friendships. Moreover, as high-achieving students play an important role in academic settings, whether they are more likely to prefer to study with similar high-achieving peers and friends was examined. SAMPLE: A total of 537 seventh-grade students from 13 classes over three waves. METHODS: Longitudinal social network analyses (RSiena). RESULTS: Adolescents were more likely to select high achievers, friends and prosocial peers as preferred academic partners. Furthermore, high achievers were more likely to choose other high achievers and friends as preferred academic partners. CONCLUSIONS: Adolescents are likely to prefer as study partners someone they can learn from and who is more approachable, cooperative and friendly. Regarding high achievers, they would choose not only academic partners with similar academic interests and motivations to help them boost their academic achievement but also classmates with whom they like to spend time and share personal issues.

RESUMO

Este estudo analisa o estresse ocupacional entre psicólogos que atuavam na Atenção Primária à Saúde durante a pandemia ocasionada pela covid-19, assim como as características sociodemográficas e laborais dos participantes e sua relação com o estresse ocupacional. Participaram da pesquisa 70 psicólogos atuantes em 51 unidades básicas de saúde das regiões Oeste e Extremo Oeste catarinense. Para coleta de dados, um questionário sociodemográfico e a versão reduzida da Job Stress Scale (JSS) foram aplicados. A análise dos dados foi realizada por meio da estatística descritiva e inferencial. Identificou-se que 35,7% dos psicólogos apresentaram alto desgaste no trabalho; 28,6% baixo desgaste; 27,1% se mostraram em trabalho passivo; e 8,6% em trabalho ativo. No modelo de regressão linear, os fatores associados à dimensão Demanda da JSS foram: possuir filho (a) (coeficiente -1,49; IC 95% -2,75 a -0,23) e afastamento do trabalho nos últimos 12 meses (coeficiente 1,88; IC 95% 0,60 a 3,15). Os psicólogos com hipertensão arterial sistêmica autorreferida apresentaram, em média, 3,96 pontos a menos no escore de Apoio social (IC 95% -7,06 a -0,85), quando comparados aos não hipertensos, e entre os psicólogos que trabalhavam no turno da manhã identificou-se aumento de 4,46 pontos, em média, no escore de Apoio social (IC 95% 0,90 a 8,02) em relação aos profissionais do turno manhã e tarde. Evidenciou-se que um número significativo de psicólogos apresentava-se em alto desgaste no trabalho, com potenciais implicações para sua saúde e atuação profissional.(AU)

This study analyzed occupational stress among psychologists who worked in Primary Health Care during the COVID-19 pandemic and participants' sociodemographic and work characteristics and their relationship with occupational stress. In total, 70 psychologists working in 51 basic health units in the West and Far West regions of Santa Catarina participated in this research. A sociodemographic questionnaire and the short version of the Job Stress Scale (JSS) were applied to collect data. Data were analyzed by descriptive and inferential statistics. In total, 35.7% of psychologists showed high stress at work; 28.6%, low burn out; 27.1%, passive work; and 8.6%, active work. The factors in the linear regression model that were associated with the JSS demand dimension referred to having children (coefficient −1.49; 95% CI −2.75 to −0.23) and absence from work in the last 12 months (coefficient 1.88; 95% CI 0.60 to 3.15). Psychologists with self-reported systemic arterial hypertension showed, on average, 3.96 points lower in the Social Support score (95% CI −7.06 to −0.85) than non-hypertensive ones and psychologists who worked in the morning shift, an average increase of 4.46 points in the Social Support score (95% CI 0.90 to 8.02) in relation to professionals working in the morning and afternoon shifts. A significant number of psychologists had high stress at work, with potential implications to their health and professional performance.(AU)

Este estudio evalúa el estrés laboral entre los psicólogos que trabajaron en la atención primaria de salud durante la pandemia provocada por la COVID-19, así como las características sociodemográficas y laborales de ellos y su relación con el estrés laboral. En la investigación participaron setenta psicólogos que trabajan en 51 unidades básicas de salud en las regiones oeste y lejano oeste de Santa Catarina (Brasil). Para la recolección de datos se aplicó un cuestionario sociodemográfico y la versión corta de la Job Stress Scale (JSS). El análisis de los datos se realizó mediante estadística descriptiva e inferencial. Se identificó que el 35,7% de los psicólogos presentaban alto estrés en el trabajo; el 28,6% tenían poco desgaste; el 27,1% se encontraban en trabajo pasivo; y el 8,6% en trabajo activo. En el modelo de regresión lineal, los factores asociados a la dimensión demanda de la JSS fueron: tener hijo (coeficiente -1,49; IC 95% -2,75 a -0,23) y baja laboral en los últimos 12 meses (coeficiente 1,88; IC 95% 0,60 a 3,15). Los psicólogos con hipertensión arterial sistémica autoinformada presentaron un promedio de 3,96 puntos más bajo en la puntuación de apoyo social (IC 95% -7,06 a -0,85) en comparación con los no hipertensos, y entre los psicólogos que trabajaban en el turno de la mañana, se identificó un aumento promedio de 4,46 puntos en la puntuación de apoyo social (IC 95% 0,90 a 8,02) con relación a los profesionales que laboran en el turno de mañana y tarde. Quedó evidente que un número significativo de psicólogos se encontraba en situación de alto estrés en el trabajo, con posibles implicaciones para su salud y desempeño profesional.(AU)

RESUMO

O diagnóstico de uma condição crônica na família tende a movimentar as relações intra e extrafamiliares. No caso do Transtorno do Espectro do Autismo (TEA), essa movimentação tende a ocorrer de forma significativa com os vínculos maternos, visto que as mães costumam ser as principais cuidadoras dos filhos com esse diagnóstico. Assim, o presente estudo objetivou investigar os impactos do diagnóstico de TEA nas redes sociais significativas maternas e como as mães lhes atribuíram sentido. Participaram 12 mães de filhos diagnosticados com TEA na infância, com as quais foram realizadas entrevistas reflexivas e construídos dois mapas de redes sociais significativas, um anterior e outro posterior ao TEA. A análise dos dados foi feita através da Grounded Theory . No momento inicial da entrevista, foi possível perceber que a maioria das participantes se referiu ao sentimento de não ter apoio, expressando desamparo. Todavia, ao longo do processo de construção dos mapas, percebeu-se relevante mudança no discurso das mães, que reconheceram e se surpreenderam com a presença de vínculos importantes nas suas redes sociais, embora, da sua perspectiva, eles não lhes proporcionem o apoio necessário. Portanto, destaca-se a importância da ativação das redes sociais significativas das mães, bem como a instrumentalização dessas redes para que possam estar presentes de maneira efetiva e fornecer apoio, salientando-se o importante papel de profissionais da saúde e da educação nesse cenário. Por fim, aponta-se o mapa de redes enquanto potente instrumento clínico e de pesquisa.(AU)

The diagnosis of a chronic condition in the family tends to move intra- and extra-family relationships. In the Autistic Spectrum Disorder (ASD) case, this movement tends to occur significantly with maternal bonds, since mothers are often referred as the main caregivers of children with this diagnosis. Thus, this study aimed to investigate the impacts of the ASD diagnosis on significant maternal social networks and how mothers signify these implications. Twelve mothers of children diagnosed with ASD in childhood participated, with whom reflective interviews were carried out and two maps of significant social networks, one before and one after the ASD, were constructed. Data analysis was performed by using Grounded Theory. At the beginning of the interview, it was possible to observe that most participants reported the feeling of having no support, expressing helplessness. However, throughout the mapping process, a relevant change was noticed in the mothers' discourse, who recognized and were surprised by the presence of important members in their social networks, although, in their perspective, they do not provide them the necessary support. Therefore, the importance of activating the mothers' significant social networks is highlighted, as well as the instrumentalization of these networks so that they can be effectively present and provide support, emphasizing the important role of health and education professionals in this scenario. Finally, the network map is pointed out as a powerful clinical and research tool.(AU)

En el caso del trastorno del espectro del autismo (TEA), este movimiento tiende a ocurrir de manera significativa con los vínculos maternos, ya que las madres son referidas como las principales cuidadoras de los niños con este diagnóstico. Este estudio tuvo por objetivo investigar el impacto del diagnóstico de TEA en las redes sociales maternas significativas y cómo las madres dieron sentido a estas implicaciones. Participaron en este estudio doce madres de niños diagnosticados con TEA en la infancia, y se utilizaron entrevistas reflexivas y mapas de redes sociales significativas, uno para antes y otro para después del TEA. El análisis de datos se basó en la teoría fundamentada. Al inicio de la entrevista, la mayoría de las participantes refirieron sentir que no tenían apoyo. Sin embargo, en el proceso de construcción de los mapas se vio un cambio en el discurso de las madres, quienes comenzaron a reconocer y sorprenderse por la presencia de vínculos importantes en sus redes sociales, aunque estos no les brindaran el apoyo necesario. Se resalta la importancia de activar las redes sociales significativas de las madres, así como la instrumentalización de estas redes para que puedan estar efectivamente presentes y brindar apoyo, enfatizando el papel de los profesionales de la salud y la educación. Además, se señala el mapa de la red como una poderosa herramienta clínica e investigativa.(AU)

RESUMO

Sintomas de ansiedade e depressão na infância têm sido amplamente investigados na atualidade. Os estudos apontam que esses sintomas têm natureza multifatorial, sendo os fatores ambientais, como as caraterísticas do funcionamento familiar, alvo de atenção dos pesquisadores. Por isso, este estudo avaliou a correlação e o poder preditivo dos fatores da parentalidade e da coparentalidade em sintomas clínicos de ansiedade e depressão nos filhos. Os participantes, 50 indivíduos que vivem em coabitação com o parceiro e têm pelo menos um filho com idade entre 7 e 11 anos, preencheram um instrumento composto por seis escalas, que avaliaram a parentalidade, a coparentalidade e a sintomatologia na prole. Os resultados indicaram correlações baixas e moderadas entre os fatores da parentalidade e da coparentalidade e os sintomas emocionais e comportamentais dos filhos. O conflito familiar coparental e a supervisão do comportamento foram preditores de 16% dos sintomas de ansiedade generalizada na prole e a triangulação familiar de 17% dos sintomas de depressão. Evidencia-se, como indica a literatura, que os filhos são suscetíveis à qualidade do funcionamento dos subsistemas parental e coparental.(AU)

Anxiety and depression symptoms in the early childhood have been investigated extensively in current times. Studies have point out that these symptoms have a multifactorial nature, with environment factors, such as the characteristics of the familiar functioning, as the researchers' target. Therefore, this study evaluated the correlation and the predictive power of parenting and co-parenting factors on clinical symptoms of anxiety and depression in the children. The participants, 50 individuals who lived in cohabitation with their partners and that had at least one child aged between 7 and 11 years old, filled in a form composed of six scales; which evaluated the parenting, the coparenting, and the offspring symptomatology. The results revealed low and moderate correlations between the parenting and coparenting variables and the emotional and behavioral symptoms of the children. The coparental familiar conflict and the behavior monitoring were predictors of 16% of the generalized anxiety symptom in the offspring, and the familiar triangulation of 17% of the depression symptoms. It shows, as the literature suggests, that the children are vulnerable to the quality of the functioning of the parental and coparental subsystems.(AU)

Los síntomas de ansiedad y depresión en la infancia son ampliamente investigados en la actualidad. Los estudios demuestran que los síntomas son multifactoriales, de los cuales los factores ambientales y las características de funcionamiento de la familia están en el centro de la atención de los investigadores. Por lo tanto, este estudio evaluó la correlación y el poder predictivo de los factores de la parentalidad y de la coparentalidad en los síntomas clínicos de ansiedad y depresión en los niños. Los participantes, 50 individuos que conviven con su pareja y tienen al menos un hijo, de entre 7 y 11 años, completaron una herramienta que se compone de seis escalas que evaluaban la crianza, la coparentalidad y la sintomatología en sus hijos. Los resultados indicaron correlaciones bajas y moderadas entre los factores de la parentalidad y de la coparentalidad y los síntomas emocionales y conductuales de los niños. El conflicto familiar coparental y la supervisión del comportamiento fueron predictores del 16% de los síntomas de ansiedad generalizada en la descendencia y la triangulación familiar del 17% de los síntomas de depresión. Esto coincide con la literatura al indicar que los niños son susceptibles a la calidad del funcionamiento de los subsistemas parental y coparental.(AU)

RESUMO

The "friendship paradox" of social networks states that, on average, "your friends have more friends than you do". Here, we theoretically and empirically explore a related and overlooked paradox we refer to as the "enmity paradox". We use empirical data from 24,678 people living in 176 villages in rural Honduras. We empirically show that, for a real negative undirected network (created by symmetrizing antagonistic interactions), the paradox exists as it does in the positive world. Specifically, a person's enemies have more enemies, on average, than a person does. Furthermore, in a mixed world of positive and negative ties, we study the conditions for the existence of the paradox, which we refer to as the "mixed-world paradox", both theoretically and empirically, finding that, for instance, a person's friends typically have more enemies than a person does. We also confirm the "generalized" enmity paradox for non-topological attributes in real data, analogous to the generalized friendship paradox (e.g., the claim that a person's enemies are richer, on average, than a person is). As a consequence, the naturally occurring variance in the degree distribution of both friendship and antagonism in social networks can skew people's perceptions of the social world.

RESUMO

Regular and moderate exercise is being used for therapeutic purposes in treating several diseases, including cancer, cardiovascular diseases, arthritis, and even chronic kidney diseases (CKDs). Conversely, extenuating physical exercise has long been pointed out as one of the sources of acute kidney injury (AKI) due to its severe impact on the body's physiology. AKI development is associated with increased tubular necrosis, which initiates a cascade of inflammatory responses. The latter involves cytokine production, immune cell (macrophages, lymphocytes, and neutrophils, among others) activation, and increased oxidative stress. AKI can induce prolonged fibrosis stimulation, leading to CKD development. The need for therapeutic alternative treatments for AKI is still a relevant issue. In this context arises the question as to whether moderate, not extenuating, exercise could, on some level, prevent AKI. Several studies have shown that moderate exercise can help reduce tissue damage and increase the functional recovery of the kidneys after an acute injury. In particular, the immune system can be modulated by exercise, leading to a better recovery from different pathologies. In this review, we aimed to explore the role of exercise not as a trigger of AKI, but as a modulator of the inflammatory/immune system in the prevention or recovery from AKI in different scenarios. In AKI induced by ischemia and reperfusion, sepsis, diabetes, antibiotics, or chemotherapy, regular and/or moderate exercise could modulate the immune system toward a more regulatory immune response, presenting, in general, an anti-inflammatory profile. Exercise was shown to diminish oxidative stress, inflammatory markers (caspase-3, lactate dehydrogenase, and nitric oxide), inflammatory cytokines (interleukin (IL)-1b, IL-6, IL-8, and tumor necrosis factor-α (TNF-α)), modulate lymphocytes to an immune suppressive phenotype, and decrease tumor necrosis factor-ß (TGF-ß), a cytokine associated with fibrosis development. Thus, it creates an AKI recovery environment with less tissue damage, hypoxia, apoptosis, or fibrosis. In conclusion, the practice of regular moderate physical exercise has an impact on the immune system, favoring a regulatory and anti-inflammatory profile that prevents the occurrence of AKI and/or assists in the recovery from AKI. Moderate exercise should be considered for patients with AKI as a complementary therapy.

RESUMO

BACKGROUND: Health education is one of the main items to enable health promotion to patients with fibromyalgia. The objective of the study "Amigos de Fibro (Fibro Friends)" is to evaluate the impact of an educational intervention associated with physical exercise based on the web in promoting health and quality of life of patients with fibromyalgia in Brazil. METHODS: A study with a randomized controlled trial approach will be carried out. The sample will consist of 24 participants, divided into two groups, with 12 individuals each. The experimental group will participate in meetings with lectures, debates, conversation rounds and exercises by a multidisciplinary team. Physical exercises will also be performed in an online environment. On the other hand, the control group will receive an e-book of education and self-care. Primary outcomes will be quality of life. The secondary outcomes will be sociodemographic and health profile, pain intensity, sleep quality, self-care agency, usage and costs of health and social care services, viability of the program and program participation. In addition, a qualitative evaluation process will be carried out with the participants. After the intervention, the data of both groups will be collected again, as well as after 3, 6, and 12 months to verify the effect and the maintenance of the intervention. DISCUSSION: The results will provide data for studies to consider the use of this tool in the future by professionals working in the field of rheumatology. TRIAL REGISTRATION: The protocol was registered in the Brazilian Registry of Clinical Trials RBR-3rh759 ( https://trialsearch.who.int/Trial2.aspx?TrialID=RBR-3rh759 ). Date of registration: 07/02/2020].

RESUMO

Ainda é desconhecido o papel da amizade enquanto constitutiva da rede de apoio social nos transtornos alimentares (TAs). Esta revisão integrativa teve por objetivo analisar a produção científica sobre relações de amizade em pessoas com TAs. Foram consultadas as bases PubMed/MEDLINE, LILACS, PsycINFO, Web of Science e EMBASE, de 2010 a 2020. Dos 1126 artigos recuperados, 15 preencheram os critérios de elegibilidade. A maioria tem abordagem qualitativa e delineamento transversal, sem indicar referencial teórico. Aspectos qualitativos das relações de amizade foram associados com redução da frequência e intensidade de sintomas quando o vínculo era considerado de boa qualidade. Já amizades que envolviam comentários depreciativos e influências negativas acerca do corpo e hábitos alimentares foram considerados fatores de risco para desencadeamento dos transtornos. Investir na qualidade dos relacionamentos entre pares pode contribuir para fortalecer a rede de proteção social e reduzir a vulnerabilidade psicossocial de adolescentes com risco para desenvolver TAs. (AU)

There is still little knowledge about the role of friendship within the social support network in eating disorders (EDs). This integrative review aimed to analyze the scientific production about friendship relationships in people with EDs. The literature review was conducted using the PubMed/MEDLINE, LILACS, PsycINFO, Web of Science, and EMBASE databases in the period from 2010 to 2020. Among the 1126 articles retrieved, 15 met the eligibility criteria, most with a qualitative approach and cross-sectional design, without indicating a theoretical framework. The qualitative aspects of friendship were associated with a reduced frequency and intensity of symptoms when the bond was considered to be of good quality. On the other hand, friendships that involved derogatory comments and negative influences related to body image and eating habits emerged as potential risk factors for triggering disorders. Investing in the quality of peer relationships can contribute to strengthening the social safety net and reducing the psychosocial vulnerability of adolescents at higher risk for developing EDs. (AU)

El papel de la amistad como constitutiva de la red de apoyo social en los trastornos alimentarios (TAs) es aún desconocido. Este estudio tiene como objetivo analizar la producción científica sobre las relaciones de amistad en personas con TAs. Se consultaron las bases PubMed/MEDLINE, LILACS, PsycINFO, Web of Science e EMBASE, entre 2010 y 2020. De los 1126 artículos recuperados, 15 cumplían los criterios de elegibilidad. La mayoría tiene enfoque cualitativo y diseño transversal, sin indicar el marco teórico. Los aspectos cualitativos de las relaciones de amistad se asociaron con una menor frecuencia/intensidad de los síntomas cuando el vínculo se consideraba de buena calidad. Amistades que implicaban comentarios despectivos e influencias negativas sobre el cuerpo y los hábitos alimentarios se consideraron factores de riesgo. Invertir en la calidad de las relaciones entre pares puede contribuir a reforzar la red de protección social y reducir la vulnerabilidad de adolescentes con riesgo de desarrollar TAs. (AU)

RESUMO

OBJECTIVE: To examine the perceptions of adolescent students from a public school, of both sexes, living in a peripheral region of the city of São Paulo, Brazil, in relation to the covid-19 pandemic, with a special focus on their experiences regarding education and sociability. METHODS: This study is part of the Global Early Adolescent Study. Seven face-to-face focus groups were conducted with adolescents between 13 and 16 years old (19 girls and 15 boys) in 2021. RESULTS: The experience of remote teaching was frustrating for the adolescents, without the daily and personalized monitoring of the teacher(s). In addition to the difficult or impossible access to devices and the lack of support from schools, there is also the domestic environment, which made the schooling process more difficult, especially for girls, who were forced to take on more household and family care tasks. The closed school blocked an important space for socialization and forced family interaction, generating conflicts and stress in the home environment. The abrupt rupture brought feelings of fear, uncertainty, anguish and loneliness. The iterative evocation of the words "stuck", "alone" and "loneliness" and the phrase "there was no one to talk to" shows how most of the adolescents experienced the period of distancing. The pandemic aggravated the objective and subjective conditions of preexisting feelings, such as "not knowing the future" and the prospects of a life project. CONCLUSION: It has been documented how pandemic control measures implemented in a fragmented way and without support for the most impoverished families have negative effects on other spheres of life, in particular for poor young people. The school is a privileged territory to propose/construct actions that help adolescents to deal with problems aggravated in/by the pandemic.

RESUMO

Oxidative stress participates at the baseline of different non-communicable pathologies such as cardiovascular diseases. Excessive formation of reactive oxygen species (ROS), above the signaling levels necessary for the correct function of organelles and cells, may contribute to the non-desired effects of oxidative stress. Platelets play a relevant role in arterial thrombosis, by aggregation triggered by different agonists, where excessive ROS formation induces mitochondrial dysfunction and stimulate platelet activation and aggregation. Platelet is both a source and a target of ROS, thus we aim to analyze both the platelet enzymes responsible for ROS generation and their involvement in intracellular signal transduction pathways. Among the proteins involved in these processes are Protein Disulphide Isomerase (PDI) and NADPH oxidase (NOX) isoforms. By using bioinformatic tools and information from available databases, a complete bioinformatic analysis of the role and interactions of PDI and NOX in platelets, as well as the signal transduction pathways involved in their effects was performed. We focused the study on analyzing whether these proteins collaborate to control platelet function. The data presented in the current manuscript support the role that PDI and NOX play on activation pathways necessary for platelet activation and aggregation, as well as on the platelet signaling imbalance produced by ROS production. Our data could be used to design specific enzyme inhibitors or a dual inhibition for these enzymes with an antiplatelet effect to design promising treatments for diseases involving platelet dysfunction.

RESUMO

Objetivo: verificar os fatores associados à alta tolerância nas relações de amizade durante o período acadêmico. Métodos: estudo transversal, analítico, realizado com 151 discentes de enfermagem de duas instituições de ensino superior privadas com coleta de dados sociodemográficos e aplicação de instrumento de avaliação da tolerância nas relações de amizade. Realizada análise por meio de estatística descritiva e regressão linear, com método backward. Resultados: verifica-se a predominância de discentes do sexo feminino, solteiras e católicas. Os discentes possuem idade média de 22,8 anos e 1,3 filhos. Reconhecer que é difícil conviver consigo; pedir desculpas, mesmo não estando errado; e acreditar que a amizade é aceitar a outra pessoa do jeito que ela é, foram fatores contribuintes para a alta tolerância. Além disso, o número de filhos contribui para o aumento da tolerância nas relações de amizade. Conclusão: a alta tolerância nas relações de amizade é importante não só para a permanência nos cursos de enfermagem, mas para o estabelecimento de vínculos interpessoais efetivos, o que reflete no comportamento em equipe, pois está relacionada à interdependência e multidisciplinaridade profissional contribuindo para a prestação de cuidado nos diversos serviços de saúde.

Objective: to verify the factors associated with high tolerance in friendships during the academic period. Methods: cross-sectional, analytical study carried out with 151 nursing students from two private educational institutions with collection of sociodemographic data and application of an instrument for assessing tolerance in friendship relationships. Analysis performed using descriptive statistics and linear regression, using the backward method. Results: there is a predominance of female, single and Catholic students. The students have an average age of 22.8 years and 1.3 children. Recognizing that it is difficult to live with you, apologizing even if you are not wrong and believing that friendship is accepting the other person as they are were contributing factors to high tolerance. In addition, the number of children contributes to increasing tolerance in friendly relationships. Conclusion: the high tolerance in friendship relationships is important not only for staying in nursing courses, but for establishing effective interpersonal bonds, which reflects in team behavior because it is related to professional interdependence and multidisciplinarity contributing to the provision of care in the various health services. (AU)

Objetivo: verificar los factores asociados a la alta tolerancia en las amistades durante el período académico. Métodos: estudio transversal, analítico realizado con 151 estudiantes de enfermería de dos instituciones educativas privadas con recolección de datos sociodemográficos y aplicación de un instrumento para evaluar la tolerancia en las relaciones de amistad. Análisis realizado mediante estadística descriptiva y regresión lineal, utilizando el método hacia atrás. Resultados: hay predominio de estudiantes mujeres, solteras y católicas. Los alumnos tienen una edad media de 22,8 años y 1,3 hijos. Reconocer que es difícil vivir consigo; pedir perdón, aunque no te equivoques; y creer que la amistad es aceptar a la otra persona como es, fueron factores que contribuyeron a una alta tolerancia. Además, el número de hijos contribuye a aumentar la tolerancia en las relaciones amistosas. Conclusión: la alta tolerancia en las relaciones de amistad es importante no solo para la permanencia en los cursos de enfermería, sino para establecer vínculos interpersonales efectivos, se refleja en el comportamiento del equipo, puesto que se relaciona con la interdependencia profesional y la multidisciplinariedad contribuyendo a la prestación de cuidados en los distintos servicios de salud.

RESUMO

Human adenoviruses (HAdV) are one of the most important pathogens detected in acute respiratory diseases in pediatrics and immunocompromised patients. In 1953, Wallace Rowe described it for the first time in oropharyngeal lymphatic tissue. To date, more than 110 types of HAdV have been described, with different cellular tropisms. They can cause respiratory and gastrointestinal symptoms, even urinary tract inflammation, although most infections are asymptomatic. However, there is a population at risk that can develop serious and even lethal conditions. These viruses have a double-stranded DNA genome, 25-48 kbp, 90 nm in diameter, without a mantle, are stable in the environment, and resistant to fat-soluble detergents. Currently the diagnosis is made with lateral flow immunochromatography or molecular biology through a polymerase chain reaction. This review aimed to highlight the HAdV variability and the pandemic potential that a HAdV3 and 7 recombinant could have considering the aggressive outbreaks produced in health facilities. Herein, we described the characteristics of HAdV, from the infection to treatment, vaccine development, and the evaluation of the social determinants of health associated with HAdV, suggesting the necessary measures for future sanitary control to prevent disasters such as the SARS-CoV-2 pandemic, with an emphasis on the use of recombinant AdV vaccines to control other potential pandemics.

RESUMO

We know little about how smoking prevention interventions might leverage social network structures to enhance protective social norms. In this study we combined statistical and network science methods to explore how social networks influence social norms related to adolescent smoking in school-specific settings in Northern Ireland and Colombia. Pupils (12-15 years old) participated in two smoking prevention interventions in both countries (n = 1344). A Latent Transition Analysis identified three groups characterized by descriptive and injunctive norms towards smoking. We employed a Separable Temporal Random Graph Model to analyze homophily in social norms and conducted a descriptive analysis of the changes in the students' and their friends' social norms over time to account for social influence. The results showed that students were more likely to be friends with others who had social norms against smoking. However, students with social norms favorable towards smoking had more friends with similar views than the students with perceived norms against smoking, underlining the importance of network thresholds. Our results support the notation that the ASSIST intervention takes advantage of friendship networks to leverage greater change in the students' smoking social norms than the Dead Cool intervention, reiterating that social norms are subject to social influence.

RESUMO

Background: Despite the efforts to promote universal coverage for family planning, inequalities are still high in several countries. Our aim was to identify which sources of contraceptives women mostly rely on in low- and middle-income countries (LMICs). We also explored the different sources according to age and marital status. Methods: We used data from national health surveys carried out in 59 LMICs since 2010. Among all sexually active women at reproductive age, we explored inequalities in demand for family planning satisfied by modern methods (mDFPS) and in the source of modern contraceptives according to women's age, classified as: 15-19, 20-34, or 35-49 years of age. Among adolescents, mDFPS and source of method were explored by marital status, classified as married or in union and not married nor in a union. Results: mDFPS was lower among adolescents than among adult women in 28 of the 59 countries. The lowest levels of mDFPS among adolescents were identified in Albania (6.1%) and Chad (8.2%). According to adolescents' marital status, the pattern of inequalities in mDFPS varied widely between regions, with married and unmarried adolescents showing similar levels of coverage in Latin America and the Caribbean, higher coverage among unmarried adolescents in Africa, and lower coverage among unmarried adolescents in Asia. Public and private health services were the main sources, with a lower share of the public sector among adolescents in almost all countries. The proportion of adolescents who obtained their contraceptives in the public sector was lower among unmarried girls than married ones in 31 of the 38 countries with data. Friends or relatives were a more significant source of contraceptives among unmarried compared to married adolescents in all regions. Conclusions: Our findings indicate lower levels of mDFPS and lower use of the public sector by adolescents, especially unmarried girls. More attention is needed to provide high-quality and affordable family planning services for adolescents, especially for those who are not married.
