Introdução: A COVID – 19, causada pelo vírus SARS – CoV-2, é uma doença infecciosa de altas consequências. O vírus é transmitido por inalação ou contato direto com gotículas infectadas. O estado nutricional interfere na resposta imune do organismo. Um bom estado nutricional pode reduzir complicações da infecção. Objetivo: Verificar as evidências do papel da nutrição no tratamento e recuperação da COVID-19. Metodologia: Este é um artigo de revisão, qual fora utilizado estudos dos anos de 2020 e 2021 encontrados na base de dados PubMed, Scielo, Google Scholar e Periódico CAPES. Resultados: Foram selecionados 15 artigos, quais as análises foram realizadas em 16 países. Dentre os estudos, 7 abordaram a respeito da suplementação nutricional, 3 em relação ao estado nutricional e comorbidades; 2 analisaram a utilização de fitoterápicos; 1 investigou o efeito de uma terapia medicamentosa; 1 apresentou a telemedicina como ferramenta frente à pandemia e 1 estudou sobre mudanças alimentares e de vida com foco na recuperação dos acometidos. Conclusão: O IMC elevado é um dos fatores que mais tem relação ao risco de mortalidade ou piora do quadro. A suplementação de micronutrientes e fitoterápicos podem auxiliar combater a infecção e diminuir o tempo de recuperação. Referente ao comportamento dos indivíduos durante o isolamento, acredita-se que a telemedicina pode ser uma ótima ferramenta para promover hábitos de vida mais saudáveis. Não existem terapias específicas comprovadas para prevenir a doença, mas uma nutrição adequada é um dos principais pontos a fim de evitar a infecção e/ou recuperar o estado nutricional.

OBJECTIVE: It is well established that obesity has a negative impact on fertility and reproductive outcomes. However, it is unclear whether pre-treatment BMI influences a subject's decision to participate in research studies focusing on body composition. This is important given that research on metabolic health may disproportionately benefit obese patients. The goal of the present analysis was to determine if pre-enrollment BMI influenced subject participation in a research study specifically evaluating body composition on IVF outcomes. DESIGN: Prospective observational study. MATERIALS AND METHODS: All patients (ages 18-45) and their partners completing an egg retrieval at a single center from 2016 to 2017 were offered participation. Subjects were contacted via telephone on the day prior to and in person on the day of the egg retrieval. Patients and partners could participate independently. Consented subjects were asked to stand on the In-Body scale which utilizes bioelectrical impedance to measure intra and extracellular water content. Consented subjects received a body analysis report. BMI was obtained from those who participated from their InBody report. Declined subject's BMI was collected from the medical record. Chi-squared analysis was used to analyze the data.RESULTS: 3,245 subjects (1,697 females and 1,548 males) were approached. 2,048 subjects participated (1,121 females and 927 males) and 1,197 subjects declined (576 females and 621 males). The enrollment among obese females (BMI R 30 kg/m 2 ) was significantly lower than non-obese (<30 kg/m 2 ) (obese females: enrolled (237/383) declined (146/383) vs. non-obese: enrolled (884/1314) declined (430/ 1314), p <0.05). There was no significant difference between obese and non-obese males (p¼0.92). Reasons for declination were as follows; 50% did not provide rationale, 25% not interested, 20% overwhelmed and 5% did not want to know their weight.CONCLUSIONS: Obese females were less likely to participate in a study evaluating the impact of body composition on IVF outcomes than non-obese females. This same phenomenon was not observed in males. Different recruitment strategies may be needed to attract these subjects who may especially benefit from the findings of the study. Furthermore, adequate recruitment of women in this category is essential to allow the most robust evaluation of the impact of body composition on IVF outcomes.
