Immunization against covid-19 and mortality in hospitalized patients: a retrospective cohort / Imunização contra covid-19 e mortalidade em pacientes hospitalizados: coorte retrospectiva

ABSTRACT OBJECTIVE To evaluate the effectiveness of vaccines developed against covid-19 in reducing mortality in people hospitalized with severe acute respiratory syndrome (SARS) caused by SARS-CoV-2. METHODS This is a retrospective cohort that evaluated risk factors and the effectiveness of the two-dose vaccination schedule in reducing the mortality of people hospitalized for covid-19 in the state of Paraíba from February to November 2021. The explanatory variables were vaccination status, presence of comorbidities, socioeconomic and demographic characteristics. Descriptive analyses and bivariate and multivariable logistic regression were performed. RESULTS Most hospitalizations and deaths occurred until May 2021. The percentage of patients with a complete vaccination schedule was similar across patients admitted to public and private hospitals and higher in residents of less developed municipalities. Multivariable analysis demonstrated that women (OR = 0.896; 95%CI 0.830-0.967) and people admitted to private hospitals (OR = 0.756; 95%CI 0.679-0.842) were less likely to die. Presence of any comorbidity (OR = 1.627; 95%CI 1.500-1.765) and age ≥ 80 years (OR = 7.426; 95%CI 6.309-8.741) were risk factors for death. Patients with complete vaccination schedule at the time of admission were 41.7% less likely to die (OR = 0.583; 95% CI 0.501-0.679) from covid-19 in the adjusted analysis, as compared to unvaccinated patients. CONCLUSIONS The study reveals that immunization was effective in reducing the likelihood of death from covid-19. The results suggest that greater vaccination coverage in the first half of 2021 would prevent thousands of deaths in the country.

RESUMO OBJETIVO Avaliar a efetividade das vacinas desenvolvidas contra a covid-19 na redução da mortalidade em pessoas internadas com síndrome respiratória aguda grave (SRAG) causada pelo SARS-CoV-2. MÉTODOS Trata-se de uma coorte retrospectiva que avaliou fatores de riscos e a efetividade do esquema vacinal com duas doses na redução da mortalidade de pessoas internadas por covid-19 no estado da Paraíba entre fevereiro e novembro de 2021. As variáveis explicativas foram situação vacinal, presença de comorbidades, características socioeconômicas e demográficas. Foram realizadas análises descritivas e regressão logística bivariada e multivariável. RESULTADOS A maior parte das internações e óbitos ocorreram até maio de 2021. O percentual de pacientes com esquema vacinal completo foi similar entre pacientes internados em hospitais públicos e privados e superior em residentes de municípios com menor desenvolvimento. A análise multivariável demonstrou que mulheres (OR = 0,896; IC95% 0,830-0,967) e pessoas internadas em hospitais privados (OR = 0,756; IC95% 0,679-0,842) apresentaram menor chance de morte. A presença de alguma comorbidade (OR = 1,627; IC95% 1,500-1,765) e idade ≥ 80 anos (OR = 7,426; IC95% 6,309-8,741) foram fatores de risco de óbito. Pacientes com esquema vacinal completo no momento da internação apresentaram uma chance 41,7% menor de morte (OR = 0,583; IC95% 0,501-0,679) por covid-19 na análise ajustada, quando comparados com pacientes não vacinados. CONCLUSÕES O estudo revela que a imunização foi efetiva na redução da chance de óbito por covid-19. Os resultados sugerem que uma maior cobertura vacinal no primeiro semestre de 2021 evitaria milhares de mortes no país.

Breastfeeding and autism spectrum disorder: case-control study / Transtorno do espectro do autismo e aleitamento materno: estudo de caso controle

Abstract Objectives: to evaluate the association between breastfeeding and Autism Spectrum Disorder (ASD) in children and adolescents. Methods: this is a case-control study carried out in the north of the state of Minas Gerais, Brazil, which included 248 children and adolescents diagnosed with ASD (case group) and 886 children and adolescents without a diagnosis of ASD (control group).Interviews were conducted with the mothers of children and adolescents and a semi-structured questionnaire was used to collect data. For data analysis, a multiple logistic regression model was adopted. The magnitude of associations was estimated by the odds ratio (OR). Three multiple models were fitted: Model 1: presence or absence of breastfeeding; Model 2: duration of breastfeeding; Model 3: duration of exclusive breastfeeding. Results: ASD was associated with the absence of breastfeeding in the three adjusted models: Model 1: OR=2.1, CI95%=1.1-4.1; Model 2: OR=2.3, CI95%=1.2-4.5; Model 3: OR=2.3, CI95%=1.2-4.5. Conclusions: individuals with ASD were more likely to have not received breastfeeding, however, due to the nature of case control studies, it cannot be stated that breastfeeding prevents ASD. Conducting a cohort study may clarify this relationship.

Resumo Objetivos: avaliar a associação entre aleitamento materno e Transtorno do Espectro do Autismo (TEA) em crianças e adolescentes. Métodos: trata-se de um estudo caso-controle realizado no norte de Minas Gerais, Brasil, que incluiu 248 crianças e adolescentes com diagnóstico de TEA (grupo caso) e 886 crianças e adolescentes sem diagnóstico de TEA (grupo controle). Foram realizadas entrevistas com as mães das crianças e adolescentes e utilizado um questionário semiestruturado para coleta dos dados. Para análise dos dados foi adotado modelo de regressão logística múltipla. A magnitude das associações foi estimada pela Odds Ratio (OR). Três modelos múltiplos foram ajustados: Modelo 1: presença ou ausência de aleitamento materno; Modelo 2: duração do aleitamento materno; Modelo 3: duração do aleitamento materno exclusivo. Resultados: o TEA foi associado à ausência de aleitamento materno nos três modelos ajustados: Modelo 1: OR=2,1, IC95%=1,1-4,1; Modelo 2: OR=2,3, IC95%=1,2-4,5; Modelo 3: OR=2,3, IC95%=1,2-4,5. Conclusões: os indivíduos com TEA tiveram maiores chances de não terem recebido aleitamento materno, no entanto, devido à natureza dos estudos de caso-controle, não se pode afirmar que o aleitamento materno previna o TEA. A realização de um estudo de coorte poderá esclarecer essa relação.

Evaluación del neurodesarrollo en niños con exposición intrauterina al virus del Zika: estudio observacional transversal / Developmental assessment of children with intrauterine exposure to Zika virus: cross-sectional observational study

El virus del Zika produce desenlaces adversos para el desarrollo del sistema nervioso. Este estudio describe el neurodesarrollo cognitivo, adaptativo, comunicativo, social y motor de niños expuestos intrauterinamente al virus del Zika y hace una evaluación del neurodesarrollo con la escala de Battelle a los tres años después del nacimiento. Participaron 30 niños con una media de edad al momento de la evaluación de 37,5 (RIC: 35,7-39,2) meses. Se halló una edad equivalente en meses en las áreas: motora 25,8 (DE: 7,8), adaptativa 26,7 (DE: 5,8), comunicativa 30,2 (DE: 6,9), personal social 33,5 (DE: 8,3) y cognitiva 35,6 (DE: 5,9). Los niños presentaron retraso en el desarrollo para la edad cronológica, 25 niños presentaban retraso en una de las cinco áreas evaluadas. Una alta proporción de niños expuestos al virus del Zika durante la gestación presentaron retraso en el desarrollo, principalmente en el dominio adaptativo y motor.

Zika virus infection affects the development of the nervous system. This study describes the cognitive, adaptative, communicative, social and motor neurodevelopment of children exposed to Zika virus in utero. We used the Batelle scale to assess neurodevelopment three years after birth. Thirty children were included, who had a mean age at evaluation of 37.5 (IQR: 35.7-39.2) months. We found the following equivalent ages in months for each area: motor 25.8 (SD: 7.8), adaptive 26.7 (SD: 5.8), communicative 30.2 (SD: 6.9), social personal 33.5 (SD: 8.3) and cognitive 35.6 (SD: 5.9). Children showed development delay for their chronological age, 25 children were delayed in one of the five areas assessed. A high rate of children exposed to Zika virus during gestation presented delayed developmental age, mainly regarding the adaptive and motor areas.

Gravidade da depressão, resposta ao tratamento e PRO (incapacidade e QoL) em pacientes com DRT em um ano de acompanhamento com tratamento padrão: análise do subgrupo brasileiro do estudo observacional multinacional TRAL / Depression severity, treatment response and PRO (disability and QoL) in TRD patients over a 1-year follow-up with standard of care: Analysis of the Brazilian subset of the multicenter, observational TRAL study

Objetivo: A depressão resistente ao tratamento (DRT) é uma preocupação primária no Brasil devido à sua natureza onerosa e complexa, enquanto o diagnóstico e o tratamento geralmente são desafiadores. O presente manuscrito apresenta os resultados clínicos de um ano de acompanhamento em pacientes com DRT em tratamento padrão (SOC) no subgrupo brasileiro do estudo de Depressão Resistente ao Tratamento na América Latina (TRAL). Métodos: Essa fase longitudinal do estudo TRAL tinha como meta caracterizar alterações nos resultados clínicos e outras variáveis de interesse (p. ex., qualidade de vida, incapacidade) em um ano de acompanhamento em pacientes com DRT em 10 centros no Brasil. Os pacientes incluídos tinham diagnóstico clínico de DRT com base nos critérios DSM-5 e confirmado por MINI. A Escala de Depressão de Montgomery-Asberg (MADRS) era usada para avaliar a gravidade da doença e os resultados clínicos. Outras escalas de depressão e instrumentos classificados pelo paciente eram usadas para medir resultados correlacionados. Resultados: Cento e cinquenta e oito pacientes com DRT, na maioria mulheres (84,4%) com idade média de 48,55 anos, foram incluídos na análise. Apenas 31,4% dos pacientes apresentaram uma resposta clinicamente significativa, 10,3% tiveram recidiva e 26,7% alcançaram remissão, conforme medido pela MADRS no final do estudo (EOS). Aproximadamente 55% dos pacientes apresentavam depressão grave/moderadamente grave no EOS. Problemas de mobilidade, cuidados pessoais, problemas nas atividades usuais e dor e desconforto foram relatados pela maioria dos pacientes no EOS, assim como comprometimento marcado/extremo das atividades no trabalho/escola e da vida social/das atividades de lazer no EOS. Conclusões: Os resultados clínicos alcançados atualmente ainda são notavelmente insatisfatórios para DRT. Portanto, o envolvimento de todas as partes interessadas é essencial para implementar protocolos de tratamento mais eficazes no Brasil.

Objective: Treatment-resistant depression (TRD) is a primary concern in Brazil due to its burdensome and complex nature, while diagnosis and treatment is often challenging. The current manuscript presents the clinical outcomes in a one-year follow-up of TRD patients under Standard-of-care (SOC) in the Brazilian subset of the Treatment-Resistant Depression in America Latina (TRAL) study. Methods: This longitudinal phase of TRAL aimed to characterize changes in the clinical outcomes and other variables of interest (e.g. quality of life, disability) in a one-year follow-up of TRD patients in 10 centers in Brazil. Included patients were clinically diagnosed with TRD based on DSM-5 criteria and confirmed by MINI. Montgomery-Asberg Depression Rating Scale (MADRS) was used to assess disease severity and clinical outcomes. Other depression scales and patient rated instruments were used to measure correlated outcomes. Results: One hundred fifty-eight TRD patients, mostly female (84.4%), averaging 48.55 years, were included in the analysis. Only 31.4% of the patients showed a clinically significant response, 10.3% had a relapse and 26.7% achieved remission, as measured through MADRS at end-of-study (EOS). Almost 55% of the patients showed moderately severe/severe depression at EOS. Mobility issues, self-care, problems with usual activities and pain and discomfort were reported by the majority of the patients at EOS, as well as marked/extreme disruption of school/work and social life/leisure activities at EOS. Conclusions: Currently achieved clinical outcomes are still remarkably unsatisfactory for TRD. Therefore, the involvement of all relevant stakeholders is essential to implement more effective treatment protocols in Brazil.

Spiritual needs among hospitalized patients at a public hospital in Brazil: a cross-sectional study

ABSTRACT BACKGROUND: The relationship between spirituality and health has been the object of growing discussion. There is a lack of data on spiritual needs assessments in Brazil. OBJECTIVE: This study aimed to assess the spiritual needs of patients admitted to a public tertiary hospital and perform a comparative analysis between patients with and without indications for palliative care. DESIGN AND SETTING: A cross-sectional observational study included patients hospitalized between August and December 2020 in Hospital do Servidor Publico Municipal, Sao Paulo, Brazil. METHODS: The included patients answered a questionnaire consisting of sociodemographic data, the Duke religiosity scale, and the Spiritual Needs Assessment for Patients (SNAP) tool for a spiritual needs assessment. The World Health Organization Palliative Needs tool (NECPAL) was used to evaluate the indications for palliative care. The level of significance adopted was 5%. RESULTS: A total of 66 patients were included in this study. Most participants (97%) declared themselves as belonging to a religion. The group without indication for palliative care by the NECPAL showed greater spiritual (P = 0.043) and psychosocial needs (P = 0.004). No statistically significant difference was observed in the religious needs domain (P = 0.176). There were no statistically significant differences in the Duke scale scores between the two groups. CONCLUSION: Spiritual, psychosocial, and religious needs are prevalent among hospitalized patients, and multidisciplinary teams must consider these needs in their management approach. In addition, this study suggests that psychosocial and spiritual needs can be even higher in patients who do not receive palliative care.

Age and Type of Delivery as Risk Indicators for Maternal Mortality / Idade e tipo de parto como indicadores de risco para mortalidade materna

Abstract Objective: This study assessed maternal mortality (MM) and related factors in a large-sized municipality in the Southeastern region of Brazil (Campinas, São Paulo) during the period 2000-2015. Methods: This study consisted of two phases: 1. An analytical nested case-control phase that assessed the impact of individual and contextual variables on MM; and 2. an ecological phase designed to contextualize maternal deaths by means of spatial analysis. The case group consisted of all maternal deaths (n = 87) and the control group consisted of 348 women who gave birth during the same period. Data analysis included descriptive statistics, association, and multiple logistic regression (MLR) tests at p < 0.05 as well as spatial analysis. Results: Maternal Mortality Ratio was 37 deaths per 100.000 live births. Deaths were dispersed throughout the urban territory and no formation of cluster was observed. MLR showed that pregnant women aged > 35 years old (OR = 2.63) or those with cesarean delivery (OR = 2.51) were more prone to maternal death. Conclusion: Maternal deaths were distributed dispersedly among the different socioeconomic levels and more prone to occur among older women or those undergoing cesarean deliveries.

Resumo Objetivo: Esse estudo avaliou a mortalidade materna (MM) e fatores relacionados em um município de grande porte da região sudeste do Brasil (Campinas, São Paulo) no período de 2000-2015. Métodos: Esse estudo consistiu de duas fases: 1. Uma fase analítica de caso-controle que avaliou o impacto de variáveis individuais e contextuais na MM; 2. Uma fase ecológica delineada para contextualizar as mortes maternas por meio de análise espacial. O grupo caso consistiu de 87 mortes maternas e o grupo controle de 348 mulheres que tiveram bebês durante o mesmo período. Os dados foram analisados por estatística descritiva, testes de associação e regressão logística múltipla (RLM) (p < 0,05) assim como análise espacial. Resultados: A taxa de mortalidade materna foi de 37 mortes para cada 100.000 nascidos vivos. As mortes foram dispersas por todo o território urbano e não se observou formação de clusters. Na RLM observou-se que mulheres grávidas com idade > 35 anos (OR = 2,63) ou aquelas que passaram por cesárea (OR = 2,51) foram mais propensas à morte materna. Conclusão: As mortes maternas foram distribuídas dispersamente entre os diferentes níveis socioeconômicos e mais propensas a ocorrer entre mulheres > 35 anos de idade ou que passaram por cesárea.

Desenlace funcional asociado al ataque cerebrovascular menor en una población colombiana: un estudio de cohorte / Functional outcome associated with minor stroke in a colombian population: a cohort study

RESUMEN INTRODUCCIÓN. El ACV menor hace referencia a un evento isquémico que cursa con síntomas leves. Se ha señalado que estos pacientes pueden presentar un desenlace clínico desfavorable. OBJETIVO: Evaluar el desenlace funcional a 90 días de pacientes con ACV isquémico menor, atendidos en dos hospitales de Bucaramanga, Colombia, entre los años 2015 y 2017. MÉTODOS. Estudio de cohorte en pacientes con ACV isquémico agudo y un puntaje NIHSS ≤ 5 puntos. Un desenlace clínico desfavorable a 90 días de seguimiento fue medido como un puntaje Rankin-m ≥ 3 puntos. Se realizó un análisis bivariado a través de modelos de regresión binomial simple y ajustado por edad y sexo. Un valor p <0,05 fue considerado estadísticamente significativo. RESULTADOS. Se incluyeron 90 pacientes (edad de 66,6± 13,5 años, 54,4% (n=49) de sexo masculino). El 36,5% (n=23) de los pacientes presentó un puntaje Rankin-m de 3 a 6 puntos. El antecedente de diabetes mellitus (RR: 2,50 IC 95%:1,33-4,70) y un Rankin-m previo de 2 (RR 2,12 IC 95%:1,39-3,24) fueron variables independientemente asociadas a discapacidad significativa. CONCLUSIÓN. Un estado funcional previamente comprometido, sumado a la disfunción endotelial que genera la diabetes mellitus, contribuye a un desenlace desfavorable en los pacientes con ACV menor.

ABSTRACT INTRODUCTION. Minor stroke refers to an ischemic vascular event that start with discrete symptoms. It has been suggested that these patients may have an unfavorable clinical outcome. AIM. To evaluate the functional outcome at 90 days in patients with minor ischemic stroke in two hospitals in Bucaramanga, between 2015 and 2017. METHODS. Cohort study in patients with acute ischemic stroke and NIHSS ≤ 5 points. An unfavorable clinical outcome was measured according to the modified Rankin Scale as ≥ 3 points. A bivariate analysis was performed through simple binomial regression models adjusted for age and sex. A p-value <0.05 was considered statistically significant. RESULTS. 90 patients were included (Aged 66.6 ± 13.5 years, 49 males (54%); 23 (36,5%) presented a modified Rankin score of 3-6 points. A history of diabetes (RR: 2.50 CI 95%: 1.33-4.70) and a modified Rankin score of 2 points prior to the event (RR 2.12 CI 95%: 1.39-3.24) were independently associated with significant disability CONCLUSION. A previously compromised functional state, added to the endothelial dysfunction generated by diabetes mellitus, contribute significantly to an unfavorable outcome in patients with minor stroke.

Tamanho do efeito em estudos observacionais na área de Saúde Bucal Coletiva: importância, cálculo e interpretação / Size effect in observational studies in Public Oral Health: importance, calculation and interpretation

Resumo O objetivo deste estudo foi analisar a literatura científica da área de saúde bucal coletiva quanto ao cálculo, apresentação e discussão do tamanho do efeito em estudos observacionais. A literatura cientifica na área (2015 a 2019) foi analisada quanto: a) informações gerais (periódico e diretrizes aos autores, número de variáveis e desfechos), b) objetivo e coerência com o cálculo amostral apresentado; c) tamanho do efeito (apresentação, medida utilizada e coerência com a discussão dos dados e conclusão). Foram analisados 123 artigos, de 66 periódicos. A maioria dos artigos avaliados apresenta um único desfecho (74%) e não menciona a realização de cálculo amostral (69,9%). Dentre os que realizaram, para 70,3% havia coerência entre o cálculo amostral utilizado e o objetivo. Apenas 3,3% dos artigos mencionam o termo tamanho do efeito e 24,4% não o consideram na discussão dos resultados, apesar de terem calculado. A regressão logística foi a metodologia estatística mais utilizada (98,4%) e o Odds Ratio a medida de tamanho do efeito mais utilizada (94,3%), embora não tenha sido citada e discutida como uma medida de tamanho do efeito na maioria dos estudos (96,7%). Os pesquisadores, em sua maioria, restringiram a discussão dos resultados apenas à significância estatística encontrada nas associações testadas.

Abstract The objective of this study was to analyze the scientific literature in public oral health regarding calculation, presentation, and discussion of the effect size in observational studies. The scientific literature (2015 to 2019) was analyzed regarding: a) general information (journal and guidelines to authors, number of variables and outcomes), b) objective and consistency with sample calculation presentation; c) effect size (presentation, measure used and consistency with data discussion and conclusion). A total of 123 articles from 66 journals were analyzed. Most articles analyzed presented a single outcome (74%) and did not mention sample size calculation (69.9%). Among those who did, 70.3% showed consistency between sample calculation used and the objective. Only 3.3% of articles mentioned the term effect size and 24.4% did not consider that in the discussion of results, despite showing effect size calculation. Logistic regression was the most commonly used statistical methodology (98.4%) and Odds Ratio was the most commonly used effect size measure (94.3%), although it was not cited and discussed as an effect size measure in most studies (96.7%). It could be concluded that most researchers restrict the discussion of their results only to the statistical significance found in associations under study.

Relação entre variáveis antropométricas e de aptidão física em crianças e adolescentes estratificados por sexo / Relationship between anthropometric and physical fitness variables in children and adolescents stratified by sex / Relación entre variables antropométricas y de aptitud física en niños y adolescentes estratificados por sexo

A aptidão física (ApF) pode estar associada à saúde, ao desempenho esportivo e refere-se a capacidade de apresentar um determinado desempenho motor quando submetido a situações que envolvam esforços físicos. O objetivo deste estudo foi relacionar as variáveis antropométricas e de aptidão física em crianças e adolescentes da cidade de Pelotas/RS, estratificados por sexo. Foram avaliados 1720 escolares da rede municipal de Pelotas/RS, sendo 896 crianças (idade = 9,91 ± 1,21 anos) e 824 adolescentes (idade = 13,11 ± 1,04 anos), através de uma bateria de avaliações das medidas antropométricas (estatura [EST], massa corporal [MC], envergadura [ENV], índice de massa corporal [IMC]) e de testes físicos (flexibilidade [FLEX], potência de membros superiores [PMS], potência de membros inferiores [PMI], velocidade com troca de direção [VTD], velocidade linear [VL], resistência muscular localizada [RML] e capacidade cardiorrespiratória [CC]). O estudo de caráter de diagnóstico com cunho observacional utilizou o teste de correlação através do r de Pearson e classificou-as como muito fraca (0-0,19), fraca (0,2-0,39), moderada (0,4-0,69), forte (0,7-0,89) e muito forte (0,9-1). Destacou-se que no sexo feminino houve correlação moderada com IMC e PMS, as variáveis antropométricas EST, ENV e MC apresentaram pelo menos uma correlação com as variáveis de ApF, enquanto que estas variáveis demonstraram correlações moderadas entre PMS, VL e VTD. Já no sexo masculino foi observada correlação moderada entre IMC e CC, além de correlações fracas e moderadas entre EST, ENV e MC com pelo menos uma das variáveis de ApF, enquanto as variáveis de ApF demonstraram correlações moderadas entre PMI, VL e VTD. Portanto, ressalta-se a importância do diagnóstico destas variáveis para controle dos fatores de risco à saúde bem como para identificar potenciais relacionados ao desempenho esportivo.

Physical fitness (PhF) can be associated with health, sports performance and refers to the ability to present a certain motor performance when submitted to situations involving physical efforts. The aim of this study was to relate anthropometric and physical fitness variables in children and adolescents from the city of Pelotas/RS, stratified by sex. A total of 1720 schoolchildren from the municipal schools of Pelotas/RS were evaluated, 896 children (age = 9.91 ± 1.21 years) and 824 adolescents (age = 13.11 ± 1.04 years), through a battery of the anthropometric measurements (height [HT], body mass [BM], wingspan [WP], body mass index [BMI]) and physical tests (flexibility [FLEX], upper limb power [ULP], lower limb power [LLP], change of direction speed [CODS], linear speed [LS], localized muscular endurance [LME] and cardiorespiratory capacity [CC]). The study of a diagnostic character with an observational nature used the correlation test through Pearson's r and classified them as very small (0-0.19), small (0.2- 0.39), moderate (0.4- 0.69), large (0.7-0.89) and very large (0.9-1). It was highlighted that in females there was moderate correlation with BMI and ULP, the anthropometric variables HT, WP and BM showed at least one correlation with the PhF variables, while these variables showed moderate correlations between ULP, LS and CODS. In males, a moderate correlation was observed between BMI and CC, in addition to small and moderate correlations between HT, WP and BM with at least one of the PhF variables, while the PhF variables showed moderate correlations between LLP, LS and CODS. Therefore, it emphasizes the importance of diagnosing these variables to control health risk factors as well as to identify potentials related to sports performance.

La aptitud física (AF) puede estar asociada a la salud, al rendimiento deportivo y se refiere a la capacidad de presentar un determinado desempeño motor cuando sometido a situaciones que impliquen esfuerzos físicos. El objetivo de este estudio fue relacionar variables antropométricas y de aptitud física en niños y adolescentes de la ciudad de Pelotas/RS, estratificados por sexo. Fueron evaluados 1720 escolares de las escuelas municipales de Pelotas/RS, 896 niños (edad = 9,91 ± 1,21 años) y 824 adolescentes (edad = 13,11 ± 1. 04 años), a través de una batería de medidas antropométricas (altura [HT], masa corporal [BM], envergadura [WP], índice de masa corporal [IMC]) y pruebas físicas (flexibilidad [FLEX], potencia de miembros superiores [ULP], potencia de miembros inferiores [LLP], velocidad de cambio de dirección [CODS], velocidad lineal [LS], resistencia muscular localizada [LME] y capacidad cardiorrespiratoria [CC]). El estudio, de carácter diagnóstico y observacional, utilizó la prueba de correlación mediante la r de Pearson y las clasificó en muy pequeñas (0-0,19), pequeñas (0,2-0,39), moderadas (0,4- 0,69), grandes (0,7-0,89) y muy grandes (0,9-1). Se destacó que en las hembras hubo una correlación moderada con el IMC y el ULP, las variables antropométricas HT, WP y BM mostraron al menos una correlación con las variables PhF, mientras que estas variables mostraron correlaciones moderadas entre ULP, LS y CODS. En los varones, se observó una correlación moderada entre IMC y CC, además de correlaciones pequeñas y moderadas entre HT, WP y BM con al menos una de las variables PhF, mientras que las variables PhF mostraron correlaciones moderadas entre LLP, LS y CODS. Por lo tanto, se destaca la importancia del diagnóstico de estas variables para controlar los factores de riesgo para la salud, así como para identificar potenciales relacionados con el rendimiento deportivo.

Target Trial Emulation and Feasibility in Traditional Chinese Medicine Researches / 中医杂志

Target trial emulation， using observational data to emulate a target trial， applies the study design principles of randomized controlled trials to observational studies that aim to estimate the effect of an intervention. The advantage of target trial emulation is that observational data is used to emulate a target trial when it is not appropriate to conduct randomized controlled trials. Target trial emulation can control bias caused by the design of observational studies， and improve the effectiveness of causal inference from observational data. This paper introduced the methodological framework and key points in terms of eligibility criteria， treatment strategies， assignment procedures， grace period， outcomes， follow-up period， effect contrasts， and statistical plan for implementing target trial emulation.

Abstract The aim of this study is to provide a real picture of the disease burden of Prameha in society. The study was performed in Government Ayurved College and Hospital, Nagpur, Maharashtra during Oct 2015-Mar 2016. Total 60 patients of newly diagnosed type 2 diabetes mellitus attending the Kayachikitsa Opd of GAC Nagpur were included for the study. The subjects details were recorded in case report form. The CRF included many variables such as sociodemographic factors, presenting symptoms, risk factors such as hypertension, obesity and glycaemic status, family history of diabetes and physical activity. Other parameters like BMI, glycosylated haemoglobin, fasting and post prandial blood sugar and fasting lipid profile were documented. Descriptive and bivariate analyses were carried out using the XLSTAT software (2020). Amongst 60 subjects, 65% were male and 93.3% were adults. 78% of subjects were following sedentary lifestyle and 40% had family history of diabetes. The results revealed that, obesity, family history of diabetes, uncontrolled glycemic status, sedentary lifestyles, and hypertension were prevalent among the Prameha subjects. The characterization of this risk profile and early detection of prameha by observing poorvarupa will contribute to designing more effective and specific strategies for screening and controlling Prameha in Maharashtra, India.

Impact of dental caries severity and activity on oral health-related quality of life among children aged 8-11 years

Abstract Caries disease can lead to strong impact in terms of pain and suffering, to functional impairment, and to negative effects on quality of life. Studies have demonstrated that the impact on quality of life increases with dental caries severity, and few studies have assessed the relationship between caries activity and children's oral health-related quality of life (OHRQoL). This cross-sectional study aimed to assess the impact of dental caries severity and activity on the OHRQoL of schoolchildren. The study was conducted with a sample of children aged 8 to 11 years from Pelotas, southern Brazil. Children answered the Child Perceptions Questionnaire 8-10, and socioeconomic data were collected. Children's dental caries (Kappa value of 0.95), PUFA, traumatic dental injuries, and malocclusion were examined. The Mann-Whitney, Kruskal-Wallis, and Poisson regression tests were performed. A total of 119 children were included. Children with initial (mean ratio (MR) of 1.92; 95% confidence interval (95% CI) of 1.05-3.48), moderate (MR: 2.66; 95%CI: 1.44-4.90), and severe carious lesions (MR: 2.65; 95%CI: 1.46-4.79) had a greater impact on OHRQoL compared with those without carious lesions (p =0 .047). Children with active carious lesions exhibited a greater impact on OHRQoL (MR:1.53 and 95%CI: 1.11-2.11) when compared to those without active lesions (p = 0.019). The findings demonstrate an association between dental caries severity and activity and the OHRQoL of school-aged children.

Factors associated with periodontal diseases in pregnancy: Findings of the 2015 Pelotas Birth Cohort Study

Abstract Although periodontal disease is common during pregnancy, little is known about socioeconomic, behavioral, or biological determinants related to clinically assessed periodontal condition during this period. We assessed the prevalence of periodontal disease and associated factors in pregnant women. This population-based survey used data used from the 2015 Pelotas Birth Cohort Study, Brazil. Pregnant women expected to give birth between December 2014 and May 2016 were interviewed and clinically examined by trained dentist, with periodontal measures collected in all teeth, six sites per tooth. Outcomes were periodontitis (using the 2012 Centers for Disease Control and Prevention and the American Academy of Periodontology criteria) and gingivitis (by the 2018 European Federation of Periodontology/ American Academy of Periodontology classification). Multivariate hierarchical Poisson regression was used to assess the associations between socioeconomic, systemic, and clinical oral factors and periodontal disease. A total of 2,474 pregnant women participated in the study. Prevalence of periodontitis and gingivitis was 14.63% and 21.67%, respectively. Lower educational level and calculus were associated with higher prevalence periodontitis and gingivitis (P<0.05). Smoking was also associated with periodontitis (P=0.05), and lower frequency of toothbrushing (P=0.005) with gingivitis. Periodontal disease, especially gingivitis, was prevalent in pregnant women and their determinants were socioeconomic, environmental, and clinical oral health factors.

Social capital and possible bruxism during the COVID-19 pandemic among Brazilian undergraduates

Abstract This study investigated the prevalence of possible bruxism and its association with social capital among undergraduates during the coronavirus disease (COVID-19) pandemic. This cross-sectional study was conducted at a private university in Southern Brazil. Data were collected through a self-administered electronic questionnaire (Google Forms). Possible bruxism was measured using the following question: "Do you grind your teeth or clench your jaws?". Social capital was evaluated using individual social networks. Data on self-perceived oral health, anxiety, sociodemographics, and information related to university graduates were also collected. Adjusted logistic regression models with a hierarchical approach were used to evaluate associations. The results are presented as odds ratios (ORs) and 95% confidence intervals (95%CIs). Altogether, 345 undergraduates participated in the study, with a mean age of 21.8 years (standard deviation = 5.21). The prevalence of bruxism in the sample was 57.1%. Undergraduates with low social capital had 2.06 times greater odds of bruxism than their counterparts (OR 2.06; 95%CI 1.11-3.83). Female undergraduates (OR 2.40, 95%CI 1.39-4.12), those who were in the final year of university (OR 1.13, 95%CI 1.04-1.21), and those who perceived they needed dental treatment (OR 1.91; CI: 1.21-3.02) also had greater odds of possible bruxism. In conclusion, the prevalence of possible bruxism was high among undergraduate students during the COVID-19 pandemic and associated with lower social capital levels. Knowledge of these factors is important to identify risk groups and plan strategies to control bruxism in this population.

El Centro de Inmunología Molecular realizó un estudio de farmacovigilancia intensiva que evalúo el cumplimiento del esquema heterólogo con ambas vacunas, su seguridad y la incidencia de casos positivos a COVID-19 en niños y adolescentes después de completar el esquema de inmunización. Desde el 15 de septiembre al 31 de diciembre del 2021, participaron 529 sujetos entre 2 y 18 años de edad, de ambos sexos, sin antecedentes de infección por coronavirus tipo 2 del síndrome respiratorio agudo severo, procedentes de 35 municipios y 12 provincias cubanas, quienes recibieron vacuna SOBERANA®02 (dos dosis) y SOBERANA®Plus (una dosis). Se realizó vigilancia de eventos adversos hasta 30 días después de la última dosis recibida. Se consultó la plataforma informática nacional Higia Andariego para identificar los casos positivos al virus del síndrome respiratorio agudo severo coronavirus 2, hasta 3 meses de haber completado la vacunación. El 98,5 por ciento de los participantes completó el esquema de vacunación y en el 6,6 por ciento se notificó algún evento adverso con relación consistente a la vacunación. Predominaron las reacciones locales (dolor, eritema, inflamación), sobre las reacciones sistémicas (fatiga y febrícula), de intensidad ligera o moderada. Se logró un elevado cumplimiento del esquema de inmunización, con un perfil de seguridad favorable, los sujetos con esquema completo de inmunización no enfermaron de COVID-19(AU)

The severe acute respiratory syndrome coronavirus 2 vaccines, SOBERANA®02 and SOBERANA®Plus, received authorization for emergency use by the Cuban regulatory authority; a massive vaccination campaign was immediately launched in the pediatric population, which led to an imminent mobilization of vaccination centers and surveillance of adverse events. The Molecular Immunology Center conducted an intensive pharmacovigilance study to evaluate compliance of the heterologous scheme with both vaccines, their safety, and the incidence of COVID-19 positive cases in children and adolescents after completing the immunization schedule. From September 15 to December 31, 2021, a total of 529 subjects between 2 and 18 years of age, of both sexes, without a history of infection by severe acute respiratory syndrome coronavirus type 2, from 35 municipalities and 12 Cuban provinces, who received SOBERANA®02 (two doses) and SOBERANA®Plus (one dose) vaccines, were included in the study. Surveillance for adverse events was performed up to 30 days after the last dose received. The national computer platform Higia Andariego was consulted to identify positive cases for severe acute respiratory syndrome coronavirus 2 up to 3 months after completing vaccination. According to the report, 98.5percent of the participants completed the vaccination schedule and 6.6percent of them reported some adverse event consistently related to vaccination. Local reactions (pain, erythema, inflammation) prevailed over systemic reactions (fatigue and fever), of light or moderate intensity. High compliance with the immunization schedule was achieved, with a favorable safety profile; subjects with a complete immunization schedule did not become ill with COVID-19(AU)

ABSTRACT Objective: to investigate in the scientific literature the factors associated with high cardiovascular risk of 10 and 30 years. Method: an integrative review of the literature conducted between July and November 2021 in the MEDLINE, CINAHL, WoS and EMBASE databases and in the Virtual Health Library portal. Duplicate articles were identified with EndNote software and the process of selecting the studies was presented in the PRISMA statement diagram. Results: 13 articles with one or more factors associated with high cardiovascular risk were selected, according to the Framingham score of 10 years. No selected article investigated the factors associated with high risk of 30 years. Poor eating habits, low socioeconomic status, low physical activity/sedentary lifestyle, impaired sleep pattern, abdominal adiposity, increased levels of Specific Prostatic Antigen in men, pre-frailty in older women, marital status (divorced or widowed man), profession (driver) and color (white woman) are associated with high cardiovascular risk of 10 years. Conclusion: risk factors that do not make up the Framingham score should be investigated during the collection of nursing data aiming at the implementation of actions to prevent and promote cardiovascular health.

Dental Fear/Anxiety in Children and Child Emotional and Behavioural Problems

ABSTRACT Objective: To investigate the association between emotional and behavioural problems and dental fear/anxiety (DFA) in children aged four to 12 years treated at a clinic in southern Brazil. Material and Methods: In this cross-sectional study where mother-child dyads were interviewed, emotional and behavioural problems were investigated using the Strengths and Difficulties Questionnaire (SDQ) (considering five subscales). Children's DFA was evaluated through the Venham Picture Test. For each SDQ subscale, Poisson regression model was explored. Prevalence ratios (PR) were estimated, considering a significant level of p ≤ 0.05. Results: Overall, 128 children participated in this study. Most children were female (54.7%) and aged between 7 and 9 years (39.8%). The prevalence of emotional problems was 47.7% and behavioural problems were 46.1%. The prevalence of DFA was 18.8%. Children with emotional problems had a 2.3 higher prevalence of DFA (95%CI 1.06-5.04). In general, behavioural problems were not associated with DFA (95%CI 0.84-3.34) only when conduct problems were considered (2.20; 95%CI 1.02-4.70). Conclusion: Children aged between 4 and 12 years who present emotional and conduct problems tend to show higher DFA.

Agreement between schoolchildren and their parents on rating the child's oral health-related quality of life

Abstract The perceptions of parents/caregivers regarding their children's oral health can influence the standard of care and decision-making regarding oral health. The children's perspective on their own oral health-related quality of life (OHRQoL) may differ from the parents/caregivers' views. This cross-sectional study aimed to analyze the agreement between the perceptions of parents/caregivers and schoolchildren regarding OHRQoL. It was conducted with a sample of children between 8 and 11 years old and their parents/caregivers from Pelotas. Children answered the Child Perceptions Questionnaire 8-10 (CPQ), and parents/caregivers answered the short form of the Parental-Caregiver Perceptions Questionnaire (P-CPQ). Socioeconomic data were also collected. Children's dental caries, traumatic dental injuries, and malocclusions were examined. The Spearman's correlation test was performed. A total of 119 parents/caregivers-children pairs were included. There was an agreement between the total scores of parents/caregivers and children (0.2770; p = 0.003), in the oral symptoms (0.1907; p = 0.038), and functional limitations (0.2233; p=0.015) domains. The Bland-Altman graph showed an agreement between children's and parents/caregivers' OHRQoL total score, but there was an underestimation of approximately two points in the parents/caregivers' perception compared to the children's score. There was an agreement between the reports of parents/caregivers and children regarding children's OHRQoL.
