Objective: To assess the association between the risk of malnutrition, as estimated by the Patient-Generated Subjective Global Assessment (PG-SGA) numerical scores, and adverse outcomes in oncology patients.
Design: Systematic review and meta-analysis.
Settings: A comprehensive search was conducted in PubMed, Web of Science, Embase, CKNI, VIP, Sinomed and Wanfang databases. Studies that examined the association between the risk of malnutrition, as estimated by the PG-SGA numerical scores, and overall survival (OS) or postoperative complications in oncology patients were included. Patients were classified as low risk (PG-SGA ≤ 3), medium risk (PG-SGA 4-8) and high risk of malnutrition (PG-SGA > 8).
Subject: Nineteen studies reporting on twenty articles ( 9286 patients).
Results: The prevalence of medium and high risk of malnutrition ranged from 16·0 % to 71·6 %. A meta-analysis showed that cancer patients with medium and high risk of malnutrition had a poorer OS (adjusted hazard ratios (HR) 1·98; 95 % CI 1·77, 2·21) compared with those with a low risk of malnutrition. Stratified analysis revealed that the pooled HR was 1·55 (95 % CI 1·17, 2·06) for medium risk of malnutrition and 2·65 (95 % CI 1·90, 3·70) for high risk of malnutrition. Additionally, the pooled adjusted OR for postoperative complications was 4·65 (95 % CI 1·61, 13·44) for patients at medium and high risk of malnutrition.
Conclusions: The presence of medium and high risk of malnutrition, as estimated by the PG-SGA numerical scores, is significantly linked to poorer OS and an increased risk of postoperative complications in oncology patients.

Background: 25-hydroxyvitamin D [25(OH)D] concentrations and physical activity (PA) are linked and both are associated with changes in mortality. We examined the association of 25(OH)D and PA with all-cause or cause-specific mortality risk in stroke survivors.
Methods: The analysis included 677 stroke survivors from National Health and Nutrition Examination Survey (NHANES) 2007-2008 to 2017-2018.
Prevalence and predictors of overweight and obesity among women of childbearing age in the province of Essaouira, Morocco.

Low- and middle-income countries are facing a rapid increase in nutritional problems, particularly in Africa, where undernutrition, overweight and micronutrient deficiencies coexist, creating a double burden of malnutrition and a challenge to public health policies. In this context, Morocco stands out for its early nutritional transition, characterized by a moderate prevalence of overweight and undernutrition and elevated levels of micronutrient deficiencies. The aim of this study was to assess the weight status of women of childbearing age and identify its determinants to suggest ways to improve it.

The purpose of this study is to (1) estimate and compare the prevalence of venous thromboembolism (VTE) in children (age 0 to ≤21) with versus without cystic fibrosis (CF); (2) investigate putative associations between specific gastrointestinal (GI) manifestations and the development of VTE among children with CF. This was a multicenter case-control analysis among patients aged 0 to ≤ 21 years between 2010 and 2020, using the TriNetX Research Network. Data queries included ICD-9/10 (International Classification of Diseases-9th/10th Revision) diagnosis codes.

Introduction: Globally, the prevalence of undernutrition is highest in the sub-Saharan African region with over a third of the world's stunted children residing in this region. Many studies have explored child nutrition in sub-Saharan Africa, but they often overlook the intricate nuances of maternal knowledge. We examined the association between maternal nutritional knowledge and childhood nutritional outcomes.
