Observational Study
Sensitivity and specificity of the new Geriatric Dehydration Screening Tool: An observational diagnostic study.
The aim of this study was to evaluate the diagnostic accuracy of the Geriatric Dehydration Screening Tool-Modified (GDST-M) in detecting dehydration in older people and, if possible, to simplify the tool and make it easier to use. ⋯ The short form of the tool is simple and contains minimally invasive assessments of low fluid intake dehydration in older people. The new GDST could also be easily used by lay people after a short training session.

The aim of this study was to explore the use of mobile health applications as dietary self-monitoring tools, and their possible role in improving food choices. ⋯ Most participants searched for information on how to improve their diet. MyFitnessPal, a mobile health app with a diet-tracking feature, was reported to be helpful in changing dietary intake; furthermore, use of the application over a 3-wk period led to a significant reduction in sugary food intake.

The present study aimed to identify associations between extremes in body weight status (underweight and excess body weight) before a COVID-19 diagnosis and clinical outcomes in patients infected with SARS coronavirus type 2. ⋯ Being underweight and excess body weight were not independently associated with clinical outcomes in patients with COVID-19 in the herein analyzed cohort. This finding indicates that the association between these variables may be confounded by both age and comorbidities.

The association between levels of circulating vitamin C and mortality remains controversial. The aim of this study was to explore the non-linear association between serum vitamin C levels and all-cause or cause-specific mortality. ⋯ Serum vitamin C levels showed a U-shaped relationship with all-cause and CVD-associated deaths among US adults using the NHANES data.

Exposure to an obesogenic environment at critical stages of human development may lead to cardiovascular damage during early adulthood, such as left ventricular hypertrophy (LVH). The objective of this study is to investigate whether the consumption of diets with different levels of fat associated with fructose drink, introduced to newly weaned rats, leads to cardiovascular damage. ⋯ The administration of diets with different fat and carbohydrate contents associated with fructose drinks introduced to newly weaned rats leads to LVH during early adulthood. The data suggest that the change in leptin-signal transducer and activator of transcription 3 pathway signaling in the groups is related to the occurrence of LVH.
