Pressão de sono e perfil acadêmico de estudante de medicina do 1º período da UFRN

Academic demands, new social context, new routines and decrease of the parental control, are factors that may influence the sleep pattern of freshman students at the University. Medical students from the Federal University of Rio Grande do Norte (UFRN) have a full-time course, subjects with high-level content, and, at the first semester, classes begin at 7 a.m. This group composed by young adults who still suffering with delayed sleep phase, common in adolescence, indicating that this class schedule can be inappropriate at this age. The reduction of nocturnal sleep during school days, and the attempt to recover sleep on free days – social jet lag (JLS), suggests that in the first semester, students suffer from high sleep pressure. High sleep pressure may reflect on cognitive tasks and performance. Therefore, the aim of this study was to investigate the relationship between sleep pressure and the academic profile of medical students from the first semester of UFRN, characterizing this population socio-demographically and investigating possible impacts on therestactivity rhytm and academic performance. A sample of 88 students, healthy men and women awswered the following questionnaires: Pittsburgh Sleep Quality (PSQI), Epworth Sleepiness Scale (ESS), Horne & Ostberg Chronotype (HO), Munich Chronotype (MCTQ) and “Health and Sleep” adapted. Actigraphy was used during 14 days to make actogramas and obtain non-parametric variables of the rest-activity rhythm and the grades of the morning schedule were used as academic performance. The JLS was used as a measure of sleep pressure. Statistics significance level was 95%. The population was sociodemographic homogeneous. Most students have healthy lifestyle, practice physical activity, use car to go to the university and take between 15 and 30 minutes for this route. Regarding CSV, most were classify as intermediate (38.6%) and evening (32%) chronotypes, needs to nap during the week, suffer daytime sleepiness and have poor sleep quality. 83% of the sample has at least 1h JLS, which led us to divide into two groups: Group <2h JLS (N = 44) and Group ≥ 2h JLS (N = 44). The groups have differences only in chronotype, showing that most evening individuals have more JLS, however, no differences were found in relation to sociodemographic aspect, rest-activity rhythm or academic performance. The homogeneity of the sample was limited to compare the groups, however, is alarming that students already present in the first half: JLG, poor sleep quality and excessive daytime sleepiness, which can be accentuated through the university years, with the emergence of night shifts and increased academic demand. Interventionsaddressingthe importance of good sleep habits and the change of the class start time are strategies aimed to improve student’s health.

Childhood obesity treatment: integrating mobile health technology into a paediatric obesity service

Background: The management of childhood obesity is challenging. Aims: Thesis, i) reviews the evidence for lifestyle treatment of obesity, ii) explores cardiometabolic burden in childhood obesity, iii) explores whether changes in body composition predicts change in insulin sensitivity (IS), iv) develops and evaluates a lifestyle obesity intervention; v) develops a mobile health application for obesity treatment and vi) tests the application in a clinical trial. Methods: In Study 1, systematic reviews and meta-analyses of the 12‐month effects of lifestyle and mHealth interventions were conducted. In Study 2, the prevalence of cardiometabolic burden was estimated in a consecutive series of 267 children. In Study 3, body composition was estimated with bioelectrical impedance analysis (BIA) and dual x-ray absorptiometry (DXA) and linear regression analyses were used to estimate the extent to which each methods predicted change in IS. Study 4 describes the development of the Temple Street W82GO Healthy Lifestyle intervention for clinical obesity in children and a controlled study of treatment effect in 276 children is reported. Study 5 describes the development and testing of the Reactivate Mobile Obesity Application. Study 6 outlines the development and preliminary report from a clinical effectiveness trial of Reactivate. Results: In Study 1, meta--‐analyses BMI SDS changed by -0.16 (-0.24,‐0.07, p<0.01) and -0.03 (-0.13, 0.06, p=0.48). In study 2, cardiometabolic comorbidities were common (e.g. hypertension in 49%) and prevalence increased as obesity level increased. In Study 3, BC changes significantly predicted changes in IS. In Study 4, BMI SDS was significantly reduced in W82GO compared to controls (p<0.001). In Study 5, the Reactivate application had good usability indices and preliminary 6‐month process report data from Study 6, revealed a promising effect for Reactivate. Conclusions: W82GO and Reactivate are promising forms of treatment.

Behaviour change techniques in home-based cardiac rehabilitation: a systematic review

BACKGROUND: Cardiac rehabilitation (CR) programmes offering secondary prevention for cardiovascular disease (CVD) advise healthy lifestyle behaviours, with the behaviour change techniques (BCTs) of goals and planning, feedback and monitoring, and social support recommended. More information is needed about BCT use in home-based CR to support these programmes in practice.

AIM: To identify and describe the use of BCTs in home-based CR programmes.

DESIGN AND SETTING: Randomised controlled trials of home-based CR between 2005 and 2015 were identified by searching MEDLINE(®), Embase, PsycINFO, Web of Science, and Cochrane Database.

METHOD: Reviewers independently screened titles and abstracts for eligibility. Relevant data, including BCTs, were extracted from included studies. A meta-analysis studied risk factor change in home-based and comparator programmes.

RESULTS: From 2448 studies identified, 11 of good methodological quality (10 on post-myocardial infarction, one on heart failure, 1907 patients) were included. These reported the use of 20 different BCTs. Social support (unspecified) was used in all studies and goal setting (behaviour) in 10. Of the 11 studies, 10 reported effectiveness in reducing CVD risk factors, but one study showed no improvement compared to usual care. This study differed from effective programmes in that it didn't include BCTs that had instructions on how to perform the behaviour and monitoring, or a credible source.

CONCLUSION: Social support and goal setting were frequently used BCTs in home-based CR programmes, with the BCTs related to monitoring, instruction on how to perform the behaviour, and credible source being included in effective programmes. Further robust trials are needed to determine the relative value of different BCTs within CR programmes.

Évaluation du programme d’intervention en nutrition «Nutriathlon en équipe (version Web)» chez des adolescents du secondaire

Les problématiques de surplus de poids sont en augmentation depuis les dernières décennies, notamment chez les jeunes québécois. Cette augmentation est en lien avec des habitudes alimentaires présentant des différences importantes avec les recommandations nutritionnelles. De plus, le gouvernement provincial a instauré des changements importants au Programme de formation de l’école québécoise afin de stimuler l’adoption de saines habitudes de vie. Afin de contrer ces problématiques de surplus de poids et d’habitudes alimentaires déficientes et de poursuivre dans la lignée de la réforme scolaire, le Nutriathlon en équipe version Web a été développé. Ce programme a pour but d’amener chaque participant à améliorer la qualité de son alimentation en augmentant et en diversifiant sa consommation de légumes, de fruits et de produits laitiers. Les objectifs de la présente étude sont (1) d’évaluer l’impact du programme sur la consommation de légumes, de fruits (LF) et de produits laitiers (PL) d’élèves du secondaire et (2) d’évaluer les facteurs influençant la réussite du programme chez ces jeunes. Les résultats de l’étude ont démontré que pendant le programme ainsi qu’immédiatement après, le groupe intervention a rapporté une augmentation significative de la consommation de LF et de PL par rapport au groupe contrôle. Par contre, aucun effet n’a pu être observé à moyen terme. Quant aux facteurs facilitant le succès du Nutriathlon en équipe, les élèves ont mentionné : l’utilisation de la technologie pour la compilation des portions, la formation d’équipes, l’implication des enseignants et de l’entourage familial ainsi que la création de stratégies pour faciliter la réussite du programme. Les élèves ont également mentionné des barrières au succès du Nutriathlon en équipe telles que le manque d’assiduité à saisir leurs données en dehors des heures de classe, la dysfonction du code d’utilisateur et l’incompatibilité de la plateforme avec certains outils technologiques comme les tablettes.

Dissecting the role of Profilin-1 in microglial cell function: the impact on ROS production

Microglial cells are the resident immune cells of central nervous system (CNS) and the major players in neuroinflammation. These cells are also responsible for surveilling the neuronal microenvironment, and upon injury to the CNS they change their morphology and molecular profile and become activated. Activated status is associated with microglia proliferation, migration to injury foci, increased phagocytic capacity, production and release of reactive oxygen species (ROS), cytokines (pro- or anti-inflammatory) and reactive nitrogen species. Microglia activation is crucial for tissue repair in the healthy brain. However, their chronic activation or deregulation might contribute for the pathophysiology of neurodegenerative diseases. A better understanding of the mechanisms underlying microglial cell activation is important for defining targets and develop appropriate therapeutic strategies to control the chronic activation of microglia. It has been observed an increase in profilin (Pfn) mRNA in microglial cells in the rat hippocampus after unilateral ablation of its major extrinsic input, the entorhinal cortex. This observation suggested that Pfn might be involved in microglia activation. Pfn1 is an actin binding protein that controls assembly and disassembly of actin filaments and is important for several cellular processes, including, motility, cell proliferation and survival. Here, we studied the role of Pfn1 in microglial cell function. For that, we used primary cortical microglial cell cultures and microglial cell lines in which we knocked down Pfn1 expression and assessed the activation status of microglia, based on classical activation markers, such as: phagocytosis, glutamate release, reactive oxygen species (ROS), pro- and anti-inflammatory cytokines. We demonstrated that Pfn1 (i) is more active in hypoxia-challenged microglia, (ii) modulates microglia pro- and anti-inflammatory signatures and (iii) plays a critical role in ROS generation in microglia. Altogether, we conclude that Pfn1 is a key protein for microglia homeostasis, playing an essential role in their activation, regardless the polarization into a pro or anti-inflammatory signature.

RELIGIOSIDADE E ESTILO DE VIDA DE UMA POPULAÇÃO ADULTA

Objetivo: Caracterizar o perfil de religiosidade e estilo de vida de uma população adulta e analisar a associação entre essas variáveis. Métodos: Pesquisa descritiva, transversal e quantitativa, realizada com participantes (n=206) de duas Feiras de Saúde na cidade de São Paulo, em 20/10/2013 e 04/05/2014. Aplicaram-se dois instrumentos, o Duke University Religion Index (DUREL, subdividido nas dimensões Religiosidade Organizacional, Não Organizacional e Intrínseca) e o Estilo de Vida FANTÁSTICO. Realizaram-se os testes Rho de Spearman para associação das variáveis “estilo de vida” e “religiosidade”, e Qui- Quadrado para análise bivariada entre sexo e religiosidade. Resultados: Encontrou-se perfil de religiosidade predominantemente bom nas três dimensões, com destaque para a Religiosidade Intrínseca, que alcançou 83,5% (n=167) nos três quesitos. Quanto ao estilo de vida (FANTÁSTICO), obteve-se a classificação de: 26,6% (n=34) “Bom”, 48,4% (n=62) “Muito Bom” e 12,5% (n=16) “Excelente”. Das 125 análises bivariadas, 13 (11,3%) apresentaram correlação fraca (ρ< 0,30), porém significativa (p<0,05). Nas associações do Qui-Quadrado, a religiosidade se relacionou às dimensões do estilo de vida quanto ao uso de álcool e drogas, alimentação equilibrada e saúde mental. Conclusão: A religiosidade na população estudada, considerando-se as três dimensões analisadas, caracterizou-se como “boa” e “muito boa”; e o estilo de vida, segundo escore total do questionário FANTÁSTICO, pôde ser considerado saudável. Apesar de fraca, confirmou-se associação entre a religiosidade e o estilo de vida.

Do Children's Health Resources Differ According to Preschool Physical Activity Programmes and Parental Behaviour? A Mixed Methods Study

Preschool can have positive effects on the development of a healthy lifestyle. The present study analysed to what extent different conditions, structures and behavioural models in preschool and family-children's central social microsystems-can lead to differences in children's health resources. Using a cross-sectional mixed methods approach, contrast analyses of "preschools with systematic physical activity programmes" versus "preschools without physical activity programmes" were conducted to assess the extent to which children's physical activity, quality of life and social behaviour differ between preschools with systematic and preschools without physical activity programmes. Differences in children's physical activity according to parental behaviour were likewise assessed. Data on child-related outcomes and parent-related factors were collected via parent questionnaires and child interviews. A qualitative focused ethnographic study was performed to obtain deeper insight into the quantitative survey data. Two hundred and twenty seven (227) children were interviewed at 21 preschools with systematic physical activity programmes, and 190 at 25 preschools without physical activity programmes. There was no significant difference in children's physical activity levels between the two preschool types (p = 0.709). However, the qualitative data showed differences in the design and quality of programmes to promote children's physical activity. Data triangulation revealed a strong influence of parental behaviour. The triangulation of methods provided comprehensive insight into the nature and extent of physical activity programmes in preschools and made it possible to capture the associations between systematic physical activity promotion and children's health resources in a differential manner.

PERCEPTIONS AND EXPERIENCES OF FAMILY CAREGIVERS OF BEDRIDDEN ELDERLY

Objective: To know the perceptions and experiences of family caregivers of bedridden elderly. Methods: A qualitative descriptive exploratory study conducted in January 2015 with four caregivers in a Family Health Center in the municipality of Araripe, CE. Data were collected through semi-structured interviews and the information was organized using the content analysis technique. A total of three categories emerged from the analysis of the reports of caregivers: the dependence process of the elderly; daily difficulties experienced by the caregiver; and satisfaction with the home care service. Results: The dependence process of the elderly took place as a consequence of pathological processes such as neoplasm, cerebrovascular accident and dementia. However, it could also be observed that physiological phenomena – common in old age – can also make individuals dependent on caregivers. As to the difficulties faced by the caregivers, they reported the need for greater involvement by the family, given that the centralization of work generates an overload and hence affects the care of the elderly. Teamwork in the home care context is fundamental, given that it allows a complementary and comprehensive care to the ledrely/caregiver binomial. Conclusion: Healthy aging is a major challenge to be overcome given that the development of a healthy lifestyle is difficult in all social strata. It is necessary to improve home care in order to provide support to caregivers so that the quality of life of bedridden elderly and caregivers is improved.

Identification of novel biomarkers to distinguish polygenic and monogenic dyslipidemia system biology approach

Dyslipidaemia is one of the major cardiovascular risk factors, it can be due to primary causes (i.e. monogenic, characterized by a single gene mutation, or dyslipidaemia of polygenic/environmental causes), or secondary to specific disorders such as obesity, diabetes mellitus or hypothyroidism. Monogenic patients present the most severe phenotype and so they need to be identified in early age so pharmacologic treatment can be implemented to decrease the cardiovascular risk. However the majority of hyperlipidemic patients most likely have a polygenic disease that can be mainly controlled just by the implementation of a healthy lifestyle. Thus, the distinction between monogenic and polygenic dyslipidaemia is important for a prompt diagnosis, cardiovascular risk assessment, counselling and treatment. Besides the already stated biomarkers as LDL, apoB and apoB/apoA-I ratio, other promising (yet, needing further research) biomarkers for clinical differentiation between dyslipidaemias are apoE, sdLDL, apoC-2 and apoC-3. However, none of these biomarkers can explain the complex lipid profile of the majority of these patients.
