Preoperative Fasting Abbreviation With Whey Protein Reduces the Occurrence of Postoperative Complications in Patients With Head and Neck Cancer: A Randomized Clinical Trial.

BACKGROUND: Surgery has become the treatment of choice for head and neck cancer (HNC) in most cases. Preoperative fasting abbreviation and nutrition screening have been suggested to reduce the occurrence of postoperative complications. This study aimed to evaluate the addition of whey protein in the preoperative fasting abbreviation and to analyze the association of nutrition status on postoperative complications in patients with HNC. METHODS: A randomized, single-blind clinical trial was performed. Patients recruited from March to November 2018 at a national cancer reference center in Brazil were divided into 2 groups: intervention group (clear fluids with carbohydrate plus whey protein [CHO-P]) and control group (clear fluids with carbohydrate only [CHO]). All patients were evaluated by the Patient-Generated Subjective Global Assessment (PG-SGA) and body mass index. Logistic regression analyses were performed to assess associations between the studied variables, generating odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: A total of 49 patients met the eligibility criteria and enrolled in the study. A PG-SGA score of 4-8, indicating moderate malnutrition (OR, 10.91; 95% CI, 1.05-112.91), was an independent factor that increased the risk of postoperative complication, whereas the CHO-P group (OR, 0.04; 95% CI, 0.01-0.26) was found to be an independent factor in reducing such risk. CONCLUSION: The addition of whey protein to clear fluids (CHO-P group) was associated with a reduced risk of postoperative complications compared with the CHO group. Furthermore, moderate malnourishment was associated with an increased risk of postoperative complications for patients with HNC.

Marcadores antropométricos de adiposidade e hipertensão arterial em academias de ginástica: um estudo exploratório / Anthropometric markers of adiposity and hypertension in Fitness Clubs: an exploratory study

Introdução: Há uma falta de conhecimento sobre o perfil de saúde das pessoas que frequentam as academias de ginástica. Objetivo: Investigar a prevalência de hipertensão arterial (HA) e sua associação com Índice de Massa Corporal (IMC) e Circunferência da Cintura (CC) em frequentadores de academias no município do Rio de Janeiro. Métodos: A amostra foi constituída de 2836 mulheres e 1707 homens com idades entre 19 e 64 anos. A HA foi diagnosticada como pressão arterial ≥140/90 mm Hg. Todas as medidas antropométricas seguiram as diretrizes preconizadas pela International Society for the Advancement of Kinanthropometry. Resultados: As prevalências de HA (10,9%), sobrepeso (30,3%) e obesidade (11,5%), foram significativamente maiores nos homens e associados com a idade, e a prevalência de CC elevada (56,6%) foi significativamente maior em mulheres e se associou com a idade (p<0,001). Apesar da prevalência de HA ter sido relativamente baixa, tanto o IMC quanto o CC mostraram-se marcadores associados a HA. Conclusão: Profissionais que trabalham em academias de ginástica devem ter conhecimento sobre a importância desses indicadores e principalmente sobre a sua relação com a HA.

Introduction: There is a lack of knowledge about the health profile of the people who attend fitness clubs. Objective: The aim of the present study was to investigate the prevalence of Hypertension and its association with anthropometric markers such as Body Mass Index (BMI) and Waist Circumference (WC) in Fitness Clubs of Rio de Janeiro City. Methods: The sample was composed of 2836 women and 1707 men (age range 19-64 years). The hypertension was diagnosed as ≥140/90 mm Hg. All anthropometric measures followed the guidelines recommended by the International Society for the Advancement of Kinanthropometry. Results: The prevalence of hypertension (10.9%), overweight (30.3%) and obesity (11.5%) were significantly higher in men and associated with age and the prevalence of high WC (56.6%) was significantly higher in women and associated with age (p<0.001). Despite the relatively low hypertension prevalence, the BMI and WC were associated the hypertension. Conclusion: Fitness clubs professionals should be aware of the importance of these markers and their relation with the hypertension.
