ABSTRACT

The objective of this review was to investigate the effect of vitamin D3 supplementation on serum 25-hydroxyvitamin D concentration in individuals with single-nucleotide polymorphisms in the vitamin D receptor gene. The research was conducted on 241 articles found in the PubMed, Scopus, Science Direct, and Cochrane Library databases between November and December 2018. After article screening, three randomized double-blind placebo-controlled clinical trials were identified as eligible for this review. Participants were Australian, Brazilian, and Chinese individuals, who ingested doses of vitamin D3 ranging from 2000 IU to a megadose of 200,000 IU. The presence of the BB/Bb genotype of the BsmI polymorphism and the FokI G allele caused an increase in the serum concentrations of vitamin D after supplementation. Nonetheless, the few studies on this subject are not unanimous in their results. It is possible that differences among populations, sample sizes, doses, and time of supplementation have an impact on data and outcomes.


El objetivo de esta revisión fue investigar el efecto de la suplementación con vitamina D3 sobre la concentración sérica de 25-hidroxivitamina D en individuos con los polimorfismos de un solo nucleótido en el gen del receptor de la vitamina D. La investigación se realizó en 241 artículos encontrados en las bases de datos PubMed, Scopus, Science Direct y Cochrane Library entre noviembre y diciembre de 2018. Después de la selección del artículo, se identificaron tres ensayos clínicos aleatorios, controlados con placebo, doble ciego, como elegibles para esta revisión. Los participantes fueron australianos, brasileños y chinos, quienes ingirieron dosis de vitamina D3 que iban desde las 2000 UI hasta una megadosis de 200,000 UI. La presencia del genotipo BB / Bb del polimorfismo BsmI y el alelo FokI G causó un aumento en las concentraciones séricas de vitamina D después de la suplementación. No obstante, los pocos estudios sobre este tema no son unánimes en sus resultados. Es posible que las diferencias entre poblaciones, tamaños de muestra, dosis y tiempo de suplementación tengan un impacto en los datos y resultados de la investigación.

ABSTRACT

INTRODUÇÃO: A triagem de risco associada à identificação do estado nutricional garante o diagnóstico precoce da desnutrição favorecendo o tratamento efetivo. A desnutrição em indivíduos hospitalizados é comum, afetando diretamente o risco nutricional, prognóstico da doença e aumentando o tempo de internação. OBJETIVO: Identificar o risco e a evolução do estado nutricional de adultos e idosos hospitalizados com distúrbios neurológicos. MÉTODOS: Estudo de caráter longitudinal e retrospectivo, desenvolvido na clínica neurológica de um hospital universitário do Recife-PE, de Janeiro a Agosto de 2018. A triagem nutricional pela Nutritional Risk Screening (NRS-2002) foi realizada em até 72 horas da admissão. Os pacientes foram avaliados na admissão e alta por meio das medidas antropométricas: peso, estatura e circunferência do braço. As análises estatísticas foram realizadas pelo Statistical Package for Social Sciences (SPSS) 21.0. RESULTADOS: Participaram do estudo 86 pacientes, o risco nutricional esteve presente em 53,5% da amostra. A média do tempo de internação foi de 22,3 +/- 14,4 dias. Houve uma associação estatisticamente significante entre a triagem de risco nutricional, o índice de massa corporal e a circunferência do braço, tanto na admissão quanto na alta. Foi evidenciada associação entre o risco nutricional e o período de internamento. DISCUSSÃO: É bem relatado na literatura que a hospitalização prolongada está associada a um maior risco de desnutrição. Fatores como a redução da ingestão alimentar associada ao aumento das necessidades energéticas e protéicas e falha na identificação do risco nutricional podem predispor ao aumento das taxas de desnutrição hospitalar. CONCLUSÃO: O risco nutricional foi presente em mais da metade da amostra estudada. Houve associação estatisticamente significante entre a triagem de risco nutricional, os parâmetros antropométricos e o período de permanência hospitalar. Quanto à evolução do estado nutricional, a maioria dos indivíduos adultos e idosos apresentou diagnóstico de eutrofia na admissão e alta


INTRODUCTION: Risk screening associated with the identification of nutritional states ensures the early diagnosis of malnutrition nutrition favoring effective treatment. Malnutrition in hospitalized individuals is common, directly affecting the nutritional risk, disease prognosis and increasing the length of stay. OBJECTIVE: Identifying the risk and the evolution of the nutritional states of hospitalized adults and elderly people with neurological disorders. METHODS: A longitudinal and retrospective study, developed at the neurological clinic of a university hospital in Recife, Brazil, from January to August 2018. Nutritional Screening by Nutritional Risk Screening (NRS 2002) was carried out within 72 hours of admission. Patients were assessed at admission and discharge by means of anthropometric measurements: weight, height and arm circumference. It was performed Statistical analyzes by the Statistical Package for Social Sciences (SPSS) 21.0. RESULTS: The study included 86 patients, the nutritional risk was present in 53.5% of the sample. The mean length of hospital stay was 22.3 +/- 14.4 days. There was a statistically significant association between nutritional risk screening, body mass index and arm circumference, both at admission and at discharge. It was evidenced an association between nutritional risk and hospitalization period. DISCUSSION:It is well reported in the literature that prolonged hospitalization is associated with an increased risk of malnutrition. Factors such as the reduction of food intake associated with increased energy and protein requirements and failure to identify the nutritional risk may predispose to increased hospital malnutrition rates. CONCLUSION: The nutritional risk was present in more than half of the sample studied. There was a statistically significant association between nutritional risk screening, anthropometric parameters and the length of hospital stay. Regarding the evolution of nutritional status, the majority of adult and elderly individuals presented a diagnosis of eutrophic on admission and discharge

ABSTRACT

OBJETIVO: Avaliar o estado nutricional e a capacidade funcional de idosos oncológicos internados em um hospital universitário de Recife, Pernambuco. MÉTODOS: Estudo transversal, desenvolvido com indivíduos com câncer, do sexo masculino e feminino, com idade ≥ 60 anos. Para a identificação do estado nutricional, foi realizada aplicação da mini avaliação nutricional, seguida da avaliação antropométrica e aferição da força de preensão manual e por fim foi avaliada a capacidade funcional. As análises estatísticas foram realizadas pelo Statistical Package for Social Sciences 21.0. O nível de significância adotado foi de 5% (p ≤ 0,05). RESULTADOS: Participaram 51 idosos sendo a maioria do sexo masculino e tendo o câncer do sistema reprodutor como o mais prevalente. A desnutrição e o risco de desnutrição pela mini avaliação nutricional estiveram presentes em 7,8% e 33,4%, respectivamente. A maioria dos idosos não apresentavam desnutrição pela avaliação antropométrica. A força da mão tanto dos homens quanto das mulheres foi considerada adequada em sua maioria e foi observada uma correlação muito fraca entre a força de preensão manual com a idade de ambos os sexos. Dos idosos, 70,6% foram classificados como dependentes funcionais. O desempenho funcional se associou positivamente com a mini avaliação nutricional, o índice de massa corporal e a circunferência da panturrilha. CONCLUSÃO: Os achados demonstraram alta prevalência do risco nutricional e uma considerável desnutrição por meio da mini avaliação nutricional. Quanto à capacidade funcional, grande parte dos idosos apresentou dependência funcional, ressaltando a necessidade de se avaliar e monitorar o estado nutricional, bem como a capacidade funcional de geriátricos oncológicos hospitalizados


OBJECTIVE: To assess the nutritional status and functional capacity of elderly oncology admitted to a university hospital in Recife, Pernambuco. METHODS: Cross-sectional study developed with individuals with cancer, male and female, aged ≥ 60 years. For the identification of the nutritional status, the mini nutritional assessment was applied, followed by the anthropometric evaluation and manual grip strength, and finally the functional capacity was evaluated. Statistical analyzes were performed by the Statistical Package for Social Sciences 21.0. The level of significance was 5% (p ≤ 0.05). RESULTS: Fifty-one elderly people participated in the research, in which the majority were male, had cancer of the reproductive system. Malnutrition and the risk of malnutrition by the mini nutritional assessment were present in 7.8% and 33.4%, respectively. Most of the elderly did not present malnutrition due to anthropometric evaluation. The hand strength of both men and women was considered to be adequate for the most part, and a very weak correlation was observed between manual grip strength and the age of both sexes. Among the elderly, 70.6% were classified as functional dependents. The functional performance was positively associated with the mini nutritional assessment, the body mass index and the calf circumference. CONCLUSION: The findings showed a high prevalence of nutritional risk and considerable malnutrition through mini nutritional assessment. Regarding functional capacity, most of the elderly had functional dependence in at least one basic daily life activity. Emphasizing the need to evaluate and monitor the nutritional status as well as the functional capacity of hospitalized geriatric oncologists

ABSTRACT

The objective of this systematic review was to analyze clinical trials carried out for the investigation of the effect of vitamin D supplementation on systemic lupus erythematosus. The research was performed from August to September 2016, without limits regarding year of publication, restriction of gender, age, and ethnicity. For the guiding question, the PICO strategy was employed. To evaluate the quality of the publications the PRISMA protocol and Jadad scale were used. The risk of bias analysis of the clinical trials was performed using the Cochrane collaboration tool. After the process of article selection and removal of duplicates, four articles were identified as eligible. The results of three studies showed a positive effect of supplementation on disease activity reduction and significant improvement in levels of inflammatory markers, fatigue, and endothelial function. Only one study showed no improvement in disease activity after supplementation. Moreover, all studies showed an increase in serum vitamin D levels. The data from this review provide evidence on the benefits of vitamin D supplementation in patients with lupus and vitamin D insufficiency/deficiency. However, it is still necessary to elucidate whether vitamin D acts in the protection against this metabolic disorder, as well as the standardization of the type, dose and time of vitamin D supplementation.

Resumo O objetivo desta revisão sistemática foi analisar ensaios clínicos feitos na investigação do efeito da suplementação com vitamina D sobre o lúpus eritematoso sistêmico. A pesquisa foi feita nas bases de dados Scopus, PubMed e Biblioteca Cochrane, de agosto a setembro de 2016, sem limite de ano de publicação, restrição de gênero, idade e etnicidade. Para a questão norteadora foi empregada a estratégia Pico. Para avaliar a qualidade das publicações usaram-se o protocolo Prisma e a escala de Jadad. A análise do risco de viés dos ensaios clínicos ocorreu pela ferramenta de colaboração Cochrane. Após o processo de seleção e remoção de artigos duplicados, quatro artigos foram identificados como elegíveis. Os resultados de três estudos mostraram efeito positivo da suplementação na redução da atividade da doença e melhoria significativa nos níveis de marcadores inflamatórios, fadiga e função endotelial. Em apenas um estudo não houve melhoria na atividade da doença após a suplementação. Ademais, todos os estudos apresentaram aumento dos níveis séricos de vitamina D. Os dados desta revisão fornecem evidências dos benefícios da suplementação com vitamina D sobre o lúpus em pacientes com insuficiência/deficiência. Contudo, ainda é necessário elucidar a atuação do nutriente na proteção contra esse distúrbio metabólico, bem como a padronização do tipo, da dose e do tempo de suplementação com vitamina D.
