Vegetarian and plant-based diets associated with lower incidence of COVID-19.

Objective: To evaluate the influence of dietary patterns on the incidence and evolution of COVID-19. We hypothesised that a plant-based diet or a vegetarian diet compared with an omnivorous diet might be associated with a lower incidence of COVID-19 infection and severity in those infected.

Design: In this observational study, 702 participants provided information on sociodemographic characteristics, dietary information and COVID-19 outcomes between March and July of 2022.

Assessment of the components of sarcopenia and quality of life perceived of individuals on hemodialysis.

Objectives: to evaluate the prevalence of sarcopenia in individuals aged 50 years or older on hemodialysis; to verify the association between sarcopenia and sociodemographic, clinical, anthropometric factors, components of sarcopenia and quality of life (QoL); and to correlate the components of sarcopenia with QoL.

Methods: Participated 83 individuals on hemodialysis. Sarcopenia was established according to the current European consensus.

Micronutrient supplementation in gastric bypass surgery: prospective study on inflammation and iron metabolism in premenopausal women.

Background: Low-grade chronic inflammation in morbid obesity is associated with impaired iron metabolism. Bariatric surgery is effective in weight loss; however, it can induce specific nutritional deficiencies, such as iron, especially in premenopausal women. Alternatively, after surgery, there is an improvement in systemic inflammation, raising questions concerning the dosages of micronutrient supplementation.

Ferritin in hypertensive and diabetic women before and after bariatric surgery.

Unlabelled: In addition to its important role as marker of iron stores, serum ferritin is a marker of systemic inflammation, and obesity has been associated with chronic inflammation.

Objective: To verify, six months after surgery, the effect of bariatric surgery on the serum ferritin of women who were hypertensive, diabetic, or comorbidity free before surgery.

Sample And Methods: This retrospective study included 200 women aged 20 to 45 years, with a body mass index (BMI) equal to or greater than 35 kg/m2, submitted to Roux-en-Y gastric bypass (RYGB).

Food intake in women two years or more after bariatric surgery meets adequate intake requirements.

Restricted food intake after bariatric surgery can be an important factor both in the long-term control of body weight and in the onset of nutritional deficiencies. The objective of this study was to assess the adequacy of food intake in women two or more years after bariatric surgery according to the excess weight lost. A group of 141 women who underwent banded Roux-en-Y gastric bypass (RYGB) was divided according to the percentage of excess weight they lost (%EWL)<50; 50┤75; = 75.

Grade of esophageal cancer and nutritional status impact on postsurgery outcomes.

Context: Undernutrition is a well known underlying cause in both disease onset and outcome.

Objective: To associate disease severity with pre surgical nutritional status, the main postsurgical complications, and mortality in esophagus cancer patients.

Method: Retrospective data from 100 patients (38-81 years old, 85% males) who had undergone esophagectomy (G1/n = 25) or gastro/jejunostomy (G2/n = 75) between 1995 and 2004.
