Neck circumference as a predictor of cardiometabolic risk and truncal obesity in people living with HIV.

Introduction: Introduction: recent studies have suggested the use of neck circumference as a parameter capable of identifying risks of cardiometabolic complications and the accumulation of truncal fat caused by both antiretroviral therapy and the lifestyle of people with the human immunodeficiency virus (HIV). Objective: to investigate the relationship between neck circumference and anthropometric indicators and to assess cardiometabolic risk and truncal obesity through proposed cut-off points. Methods: cross-sectional study including 233 people with HIV. Demographic, socioeconomic, lifestyle and clinical data were collected using a structured questionnaire. The anthropometric evaluation included: weight, height, body mass index (BMI) measurements; waist (WC), neck (NC), arm and arm muscle circumferences; triceps and subscapular skinfolds and their sum. ROC curves were constructed to determine the accuracy of NC in predicting cardiometabolic risk in people living with HIV. Results: the sample was 57.5 % male, with a mean age of 38.4 years (95 %CI: 37.2-39.7 years). NC showed a positive and significant correlation with all anthropometric variables analyzed (p < 0.05), and a higher correlation strength with WC and BMI. The NC cut-off point selected as a predictor of risk of cardiac metabolic complications and truncal obesity in women was ≥ 32.4 cm, considering both WC and BMI. For men, the NC cut-off points were different when considering WC (≥ 39.6 cm) and BMI (≥ 38.1 cm) as a reference. It is worth noting that NC performed well in ROC curve analysis for men, while in women it was a poor performance. Conclusion: NC proved to be a promising indicator in the assessment of nutrition and health of people living with HIV, especially in men.

Introducción: Introducción: estudios recientes han sugerido el uso de la circunferencia del cuello como parámetro capaz de identificar los riesgos de complicaciones cardiometabólicas y la acumulación de grasa troncal causados tanto por la terapia antirretroviral como por el estilo de vida de las personas con el virus de la inmunodeficiencia humana (VIH). Objetivo: investigar la relación entre la circunferencia del cuello y los indicadores antropométricos y evaluar el riesgo cardiometabólico y la obesidad troncal a través de los puntos de corte propuestos. Métodos: estudio transversal que incluyó a 233 personas con VIH. Se recogieron datos demográficos, socioeconómicos, de estilo de vida y clínicos mediante un cuestionario estructurado. La evaluación antropométrica incluyó: medidas de peso, altura, índice de masa corporal (IMC); circunferencias de cintura (CC), cuello (CN), brazo (CA) y músculo del brazo (MCB); pliegues cutáneos del tríceps y subescapular y su suma. Se construyeron curvas ROC para determinar la precisión de la CN en la predicción del riesgo cardiometabólico en personas que viven con el VIH. Resultados: el 57,5 % de la muestra eran varones, con una edad media de 38,4 años (IC 95 %: 37,2-39,7 años). La CN mostró una correlación positiva y significativa (p < 0,05) con todas las variables antropométricas analizadas, y una mayor fuerza de correlación con la CC y el IMC. El punto de corte de la CN seleccionado como predictor de riesgo de complicaciones metabólicas cardiacas y obesidad troncular en mujeres fue ≥ 32,4 cm, considerando tanto la CC como el IMC. En el caso de los hombres, los puntos de corte de la CN fueron diferentes al considerar como referencia la CC (≥ 39,6 cm) y el IMC (≥ 38,1 cm). Cabe destacar que la CN obtuvo buenos resultados en el análisis de la curva ROC en el caso de los hombres, mientras que en el de las mujeres fue deficiente. Conclusión: la CN demostró ser un indicador prometedor en la evaluación de la nutrición y la salud de las personas que viven con el VIH, especialmente en los hombres.

Prevalence of prediabetes in adults and its association with sociodemographic, nutritional, metabolic and mental disorders factors: Home Health Survey, Piauí, Brazil / Prevalência de pré-diabetes em adultos e sua associação com fatores sociodemográficos, nutricionais, metabólicos e transtornos mentais: Inquérito de Saúde Domiciliar, Piauí, Brasil

ABSTRACT Objective To estimate prevalence of prediabetes and to investigate its associated factors in adults living in Teresina, Piauí, Brazil Methods Cross-sectional, home-based study, with both genders adults in Teresina, Piauí. The prevalence of prediabetes was estimated using the fasting glucose test, and was classified according to the American Diabetes Association standards (≥100mg/dL; <126mg/dL). The associations between prediabetes and the variables: sociodemographic, anthropometric, food consumption, blood pressure levels, triglycerides and common mental disorders were tested. In addition, a variable was created to verify the association of the simultaneous presence of risk factors in the same individual. Data were reviewed using Pearson's chi-square test and Poisson regression for crude and adjusted prevalence ratios, considering a significance level of 5%. Results A total of 224 adults participated in the study, of which 154 (68.7%) were female, aged between 20 and 39 years (53.1%). An 8.04% prevalence of prediabetes was observed. A statistically significant association (p<0.05) was found between lower education (0 to 8 years of study; 17.3%) and increased triglycerides levels (≥150mg/dL; 13.7%). Higher gross prevalence (PR: 2.53; CI 95%: 1.05-6.05) prediabetes ratios were observed with 5 or more simultaneous risk factors when compared to individuals who had up to 4 simultaneous risk factors. Conclusion Low schooling, hypertriglyceridemia and the presence of five or more simultaneous risk factors were associated with prediabetes; however, these risk factors are subject to intervention. Therefore, this study points to the need for changes in lifestyle habits as a strategy for glycemic control and diabetes prevention.

RESUMO Objetivo Estimar a prevalência de pré-diabetes e investigar os fatores associados em adultos residentes em Teresina, Piauí, Brasil. Métodos Estudo transversal de base domiciliar com adultos de ambos os sexos em Teresina, Piauí. A prevalência de pré-diabetes foi estimada pelo teste de glicemia em jejum, e classificado de acordo com a Associação Americana de Diabetes (≥100mg/dL; <126mg/dL). Foram testadas as associações entre pré-diabetes e as variáveis: sociodemográficas, antropométricas, consumo alimentar, níveis pressóricos, triglicerídeos e transtornos mentais comuns. Além disso, foi criada uma variável para verificar a associação da presença simultânea dos fatores de risco no mesmo indivíduo. Os dados foram analisados com o teste do qui-quadrado de Pearson e regressão de Poisson para razões de prevalência bruta e ajustada, considerando nível de significância de 5%. Resultados Participaram do estudo 224 adultos, sendo 154 (68,7%) do sexo feminino, entre 20 e 39 anos (53,1%). Verificou-se prevalência de pré-diabetes de 8,04%, com associação significativa (p<0,05) com a menor escolaridade (17,3%), e triglicerídeos elevados (13,7%). Observou-se maior razão de prevalência bruta (RP: 2,53; IC 95%: 1,05-6,05) de pré-diabetes nos indivíduos com 5 ou mais fatores de risco simultâneos quando comparados àqueles com até 4 fatores simultâneos. Conclusão A baixa escolaridade, a hipertrigliceridemia e a presença de cinco ou mais fatores de risco simultâneos apresentaram-se associados ao pré-diabetes. Entretanto, os fatores de risco encontrados são passíveis de intervenção. Este estudo aponta a necessidade de mudanças de hábitos de vida comportamentais como estratégia para o controle da glicemia e prevenção do diabetes.

Effects of vitamin D supplementation on the glycemic control of pre-diabetic individuals: a systematic review.

INTRODUCTION: Introduction: research shows the potential effect of vitamin D supplementation with an improvement in the glycemic profile of pre-diabetic patients. Objective: this study evaluates the effects of vitamin D supplementation on glycemic control markers in pre-diabetic individuals. Methods: we analyzed studies published over the last ten years, and indexed in the Science Direct, PubMed, and LILACS databases. We searched studies using health descriptors related to vitamin D, pre-diabetes, and glycemic control markers. We considered randomized controlled trials eligible for inclusion. All phases of selection, data extraction, and risk of bias assessment were carried out by two independent evaluators. Results: we identified 309 articles, of which 4 met the inclusion criteria. Of these, 3 studies have shown that vitamin D supplementation does not alter glycemic control markers in pre-diabetic individuals. Only one study showed a positive effect after supplementation with 60,000 IU/month of vitamin D3 for 12 months, with a significant reduction in the concentrations of glycated hemoglobin, fasting glucose, and two-hour postprandial glucose. Conclusion: there is insufficient scientific evidence to confirm the beneficial effects of vitamin D supplementation on glycemic control markers in pre-diabetic individuals.

INTRODUCCIÓN: Introducción: las investigaciones muestran el efecto potencial de la suplementación con vitamina D con una mejora del perfil glucémico de los pacientes prediabéticos. Objetivo: este estudio evalúa los efectos de la suplementación con vitamina D sobre los marcadores de control glucémico en personas prediabéticas. Métodos: analizamos los estudios publicados en los últimos diez años e indexados en las bases de datos Science Direct, PubMed y LILACS. Se realizaron búsquedas de estudios mediante descriptores de salud relacionados con la vitamina D, la prediabetes y los marcadores de control glucémico. Los ensayos controlados y aleatorizados se consideraron elegibles para su inclusión. Todas las fases de selección, extracción de datos y evaluación del riesgo de sesgos fueron realizadas por dos evaluadores independientes. Resultados: identificamos 309 artículos, de los que 4 cumplieron los criterios de inclusión. De estos, 3 estudios demostraron que la suplementación con vitamina D no altera los marcadores de control glucémico en las personas prediabéticas. Solo un estudio mostró un efecto positivo después de la suplementación de 60.000 UI/mes de vitamina D3 durante 12 meses, con una reducción significativa de las concentraciones de hemoglobina glucosilada, glucosa en ayunas y glucosa posprandial a las dos horas. Conclusión: no hay evidencia científica suficiente para confirmar los efectos beneficiosos de la suplementación de vitamina D sobre los marcadores de control glucémico en las personas prediabéticas.

Impact of intermittent fasting on body weight in overweight and obese individuals.

OBJECTIVE: To verify the relationship of intermittent fasting in the bodyweight of overweight and obese individuals through a systematic literature review. METHODS: This is a systematic review based on randomized controlled trials. The articles were consulted in the databases: Science Direct, PubMed e BVS. This review was evaluated through the PRISMA recommendation. RESULTS: After the selection process, four articles were included in this review, comparing intermittent fasting (IF) with calorie restriction diet (CRD) as a control group. In 2 studies using similar protocols, there was no significant reduction in body weight of overweight or obese subjects. In the other two studies using different protocols, weight loss was significant in the IF group compared to the CRD group. CONCLUSIONS: Results did not provide evidence of the effect of intermittent fasting on weight loss in overweight or obese individuals.

Effect of vitamin D3 supplementation on HIV-infected adults: a systematic reviewVitamin DÓ¡ Supplementation on HIV-Infected Adults: A Systematic Review.

INTRODUCTION: Introduction: much evidence confirms that vitamin D may be associated with an improvement in CD4 cell counts in HIV-infected individuals, where antiretroviral therapy (ART) is used and associated with decreased 25(OH)D levels. Objective: to carry out a systematic review on the effect of vitamin D supplementation on HIV-infected adult patients. Methods: the research was conducted in the databases Science Direct, PubMed, BVS, Scielo Cochrane and Periods, from February to April 2018, with publication limit from 2000 to 2018, without restriction of gender, ethnicity and involving individuals with age older than 18 years. To evaluate the quality of the studies, we used the protocol Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) and the Jadad scale. Results: the search initially resulted in 198 articles. After the selection process 5 articles were identified as eligible, where they highlight that vitamin D supplementation may be an associated and effective intervention to reduce hypovitaminosis. ART reduces vitamin D3 levels and changes its metabolism, being associated with the risk of mortality. However, adequate levels of 25(OH)D are positively associated with the number of CD4 + cells and the reduction of infection levels. Conclusion: vitamin D supplementation promotes immune recovery. However, the cases analysed were few, insufficient to fully confirm the benefits and recommend supplementation. Therefore, intervention studies are needed to elucidate the role of vitamin D in human protection against HIV infections.

INTRODUCCIÓN: Introducción: muchas evidencias ratifican que la vitamina D puede estar asociada con la mejora de los niveles de células CD4 en individuos infectados por el VIH, tratados con terapia antirretroviral (ART) que se asocia a la disminución de los niveles de 25(OH)D. Objetivo: realizar una revisión sistemática sobre el efecto de la suplementación de vitamina D en pacientes adultos infectados con VIH. Métodos: la investigación fue realizada en las bases de datos Science Direct, PubMed, BVS, Scielo Cochrane y periódicos, de febrero a abril de 2018, con límite de publicación de 2000 a 2018, sin restricción de género, etnicidad y que involucra a individuos con edad mayores de 18 años. Para la evaluación de la calidad de los estudios, se utilizó el protocolo Preferred Reporting Items for Systematic Reviews y Meta-Analyzes (PRISMA) y la escala de Jadad. Resultados: la encuesta inicialmente resultó en 198 artículos. Después del proceso de selección, 5 artículos fueron identificados como elegibles, donde ponen de manifiesto que la suplementación con vitamina D puede ser una intervención asociada y eficaz para reducir la hipovitaminosis. La ART reduce niveles de la vitamina D3 y altera su metabolismo, estando asociada al riesgo de mortalidad. Sin embargo, los niveles adecuados de 25(OH)D están asociados positivamente al número de células CD4 + y la reducción de los niveles de infecciones. Conclusión: la suplementación de vitamina D promueve la recuperación inmunológica. Sin embargo, los casos analizados fueron pocos, insuficientes para confirmar totalmente los beneficios y recomendar la suplementación. Por lo tanto, estudios de intervención son necesarios para elucidar la actuación de la vitamina D en la protección humana contra las infecciones por el VIH.

Nurse training in primary care: educational actions with people living with Diabetes mellitus / Formação do enfermeiro na atenção básica: ações educativas com pessoas que vivem com Diabetes mellitus

Educational actionswith people living with chronic conditions, especially Diabetes mellitus, are a challenge and a necessary strategy in Primary Care, in view of the glycemic balance, the prevention of complications and the improvement of the quality of life. This study aimed to analyze nurse training in educational actions developed in Primary Care with people living with Diabetes mellitus. A qualitative research was conducted with 28 nurses of Primary Care, in Teresina, state of Piauí, Brazil. Data were collected from April to June 2015 through interviews and analyzed by the collective subject discourse technique. The construction of the results was based on four sequential questions made in the interviews, from which emerged 15 central ideas: lectures, group orientation, nursing consultation and home care; theoretical knowledge, practical knowledge, technical knowledge and expertise knowledge; few materials and infrastructure in the basic unit, lack of professional teamwork, reduced workload and little awareness of teachers; and promotion of care and and self-care, family support and prevention of complications. In the analysis of the discourses, it was possible to conclude about the need for Permanent Health Education in Primary Care.

As ações educativas com pessoas que vivem com condições crônicas, em especial com Diabetes mellitus, apresentam-se como um desafio e uma estratégia necessária na Atenção Básica, tendo em vista o equilíbrio glicêmico, a prevenção de complicações e a melhoria da qualidade de vida. Neste estudo objetivou-se analisar a formação do enfermeiro sobre ações educativas desenvolvidas na Atenção Básica com pessoas que vivem com Diabetes mellitus. Realizou- se pesquisa de natureza qualitativa, com 28 enfermeiros da Atenção Básica, em Teresina, Piauí, Brasil. Os dados foram coletados de abril a junho de 2015, por meio de entrevistas e analisados pelo discurso do sujeito coletivo. A construção dos resultados foi realizada com base nas quatro questões sequenciais realizadas nas entrevistas, das quais emergiram 15 ideias centrais: palestras, orientação em grupo, consulta de enfermagem e atendimento domiciliar; conhecimento teórico, conhecimento prático, conhecimento técnico e conhecimento especializado; poucos materiais e infraestrutura na unidade básica, ausência da atuação de profissionais em equipe, carga horária reduzida e pouca sensibilização dos professores; e, promoção de cuidado e autocuidado, apoio familiar e prevenção de complicações. Na análise dos discursos dos enfermeiros, foi possível concluir sobre a necessidade de Educação Permanente em Saúde na Atenção Básica.
