Furthermore, the ability of urinary and blood biomarkers to monitor small hydration changes have not been solidified. There were two objectives of this research: 1. Determine if mild dehydration affects plasma and serum volume; 2. Determine if mild dehydration can be detected better by urinary or blood biomarkers. 47 subjects were recruited; 10 subjects were removed from the study and 37 subjects (27% male) completed the study. This was a crossover study design such that each subject underwent all protocols in a counterbalanced order. Protocols consisted of 12-h dehydration, 12-h hydration, and control. Neither plasma volume (p = 0.914), plasma volume status (p = 0.649), nor serum volume (p = 0.273) were different among protocols. Body mass (p < 0.001) was lower following the dehydration protocol. Urine color (p < 0.001), urine osmolality (p < 0.001), urine specific gravity (p < 0.001), serum osmolality (p < 0.001), and plasma osmolality (p < 0.001) were all lower following the hydration protocol. Hematocrit (p = 0.842) and hemoglobin concentration (p = 0.558) were not different among protocols. Dehydration did not affect plasma or serum volume. Therefore, a 12-h fast from food and water as done in this study will not likely affect laboratory test results of biomarker concentration. All 3 urinary measures were able to detect changes in hydration status, whereas only 2 blood measures were able to detect changes in hydration status. This may indicate that urinary measures are best at detecting small changes in hydration status.","PeriodicalId":11927,"journal":{"name":"European Journal of Clinical Nutrition","volume":"79 2","pages":"161-167"},"PeriodicalIF":3.6,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41430-024-01526-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142460974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The importance of nutrition in addressing geriatric syndromes such as frailty, sarcopenia, osteosarcopenia, obesity and metabolic syndrome is highlighted. Dysphagia, frequent in the elderly, requires special attention to prevent malnutrition and complications. It is essential to maintain muscle mass and bone health in old age.

However, measuring GIT function is increasingly important with the emerging relevance of childhood environmental enteropathy (EE) as a mediating factor in linear growth faltering, severe acute malnutrition, poor oral vaccine uptake and impaired cognition. In EE, sub-optimal nutrient digestion and absorption (malabsorption) forms the critical link to the conditions mentioned above. The present narrative review discusses probable mechanisms that can cause malabsorption of macronutrients, along with mechanistic and experimental evidence, in children (if not, in adults) with EE. The strengths and limitations of the human experimental studies are examined in relation to a battery of existing and potential tests that are used to measure malabsorption. From the available studies conducted in children, lactose and fat malabsorption are more likely to occur in EE. Breath tests (non-invasive) measuring carbohydrate (13C-starch/sucrose/lactose), fat (13C-mixed triglyceride) and dipeptide (benzoyl-L-tyrosyl-L-1-13C-alanine) malabsorption with modifications to the existing protocols seem suitable for use in children with EE. Future research should focus on understanding the degree of macronutrient malabsorption using these tests, in different settings, and link them to functional outcomes (such as growth, muscle strength, cognition).","PeriodicalId":11927,"journal":{"name":"European Journal of Clinical Nutrition","volume":"79 3","pages":"181-194"},"PeriodicalIF":3.6,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41430-024-01510-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142389043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to investigate the effectiveness of a MVM supplement on meaningful outcomes of everyday functioning in older adults. This randomised, double-blind, placebo-controlled, parallel groups trial investigated the effects of 12-week MVM supplementation on measures of wellbeing, mood, and memory; physical health and activity; and social interaction and loneliness. Outcomes were measured at baseline and after 12 weeks in a sample of 228 (124 female) older adults ( &gt; 70 years). MVM supplementation had no effect on the primary outcome of wellbeing (p = 0.29 in males, p = 0.421 in females), but led to increased feelings of friendliness in females (p = 0.045). In males, following MVM, there were lower levels of prolonged stress reactivity (p = 0.007), lower overall stress reactivity (p = 0.019), and lower emotional loneliness (p = 0.042). This study provides novel evidence of increased friendliness and decreased stress reactivity and loneliness following MVM supplementation in older adults. These findings support the exploration of broader functions pertinent to aspects of daily living in older adults. Sex differences in response highlight the importance of exploring effects in men and women separately and support a recommendation for the inclusion of diverse samples in future research that are representative of the population.","PeriodicalId":11927,"journal":{"name":"European Journal of Clinical Nutrition","volume":"79 2","pages":"126-135"},"PeriodicalIF":3.6,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41430-024-01517-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142371276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Malnutrition was diagnosed according to the GLIM criteria. The diagnostic value of GNRI, PNI, and COUNT scores in identifying GLIM-defined malnutrition was assessed by conducting Receiver Operating Characteristic (ROC) curves and calculating the area under the curve (AUC). Additionally, sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) were determined.

A total of 316 patients were enrolled in this study, and malnutrition was diagnosed in 151 (47.8%) patients based on the GLIM criteria. The GNRI demonstrated good diagnostic accuracy (AUC = 0.805, 95% CI: 0.758–0.852) for detecting GLIM-defined malnutrition, while the PNI and COUNT score showed poor diagnostic accuracy with AUCs of 0.699 (95% CI: 0.641–0.757) and 0.665 (95% CI: 0.605–0.725) respectively.
