Sex-related differences in eating behaviors during COVID-19 pandemic: A systematic review with metanalysis.

Eating behavior can be influenced by external factors; however, there is no consensus on the existence of differences in eating behavior between the sexes in stressful situations, such as the COVID-19 pandemic. This systematic review assessed whether there was a difference in eating behavior between sexes during the COVID-19 pandemic. A search of nine databases (Medline/Pubmed, Embase, Scielo, VHL, Scopus, PsycINFO, Web of Science, ProQuest, Google Scholar) was conducted in October 2023.

Seasonal and sex-related variation in vitamin D status and its association with other biochemical markers in young individuals: A cross-sectional study.

Background: While several studies have investigated the association between vitamin D deficiency and biochemical parameters, the results are still inconsistent and mostly overlook seasonal variations. This study explored the relationships between 25-hydroxy-vitamin D (25(OH)D) concentrations, biochemical markers, and seasonal variation among young males and females.

Methods: A cross-sectional study was conducted among 203 individuals aged 18-24 years of both sexes residing in Brasilia, Brazil (latitude: 15°S).

Development and Validation of Protocol Based on Brazilian Dietary Guidelines for Adults with Diabetes Mellitus Who Attended Primary Health Care.

Background: To date, there is no protocol providing dietary guidelines to assist health care professionals in counseling Brazilian individuals with Diabetes Mellitus (DM) assisted in primary health care (PHC) according to the Dietary Guidelines for the Brazilian Population (DGBP). Therefore, this study aimed to develop and validate a protocol based on the DGBP for health care, non-nutritionist professionals in counseling adults with DM in PHC.

Methods: We systematized the recommendations published in the DGBP, the Diabetes Brazilian Society guidelines, and the scientific literature regarding food and nutrition needs of adults with DM.

Determinant factors of bone health after long-term of Roux-en-Y gastric bypass surgery: A cross-sectional study.

Objectives: The aim of this study was to evaluate bone health and the potential influencing factors of bone metabolism disorders in adults ≥5 y after Roux-en-Y gastric bypass (RYGB) surgery.

Methods: In this cross-sectional study, patients who were ≥5 y post-RYGB were invited. Bone health considered as bone mineral content (BMC) and bone mineral density (BMD) in this study was assessed by dual x-ray absorptiometry.

Probiotics, prebiotics, and synbiotics in chronic constipation: Outstanding aspects to be considered for the current evidence.

This integrative aimed to evaluate the effects and the potential mechanism of action of prebiotics, probiotics, and synbiotics on constipation-associated gastrointestinal symptoms and to identify issues that still need to be answered. A literature search was performed in the PubMed database. Animal models ( = 23) and clinical trials ( = 39) were included.

The effect of probiotics on postsurgical complications in patients with colorectal cancer: a systematic review and meta-analysis.

Context: Clinical trials have investigated the effect of probiotics on postsurgical complications in colorectal cancer (CRC). However, so far, there are no systematic reviews evaluating the effect of probiotics and synbiotics on the clinical or infectious postsurgical complications of colorectal cancer.

Objective: The objective of this review was to synthesize the best available evidence on the effects of the use of probiotics or synbiotics on pre-, peri-, and post-operative complications of CRC surgical resection.

Frequency of Vitamin D Deficiency and Associated Factors in Long-term Bariatric Surgery Patients: a Cross-sectional Study.

Background: Vitamin D deficiency is a common consequence of bariatric surgery (BS). However, few studies have evaluated influential factors and to date there are no studies investigating individual ultraviolet B (UVB) radiation levels in BS patients. This study aimed to evaluate vitamin D deficiency and its associated factors, including UVB radiation, in Roux-Y gastric bypass (RYGB) patients.

Effects of Bifidobacterium animalis subspecies lactis supplementation on gastrointestinal symptoms: systematic review with meta-analysis.

Context: The effects of probiotics on gastrointestinal (GI) symptoms have been increasingly investigated, particularly that of Bifidobacterium animalis. Clinical trials so far have shown differing evidence regarding these effects in healthy adults.

Objective: To synthesize the published evidence on the effects of B.
