Filter by:During the Covid-19 pandemic, admission patterns for infections other than Covid-19 have changed dramatically among children worldwide. Particularly admissions due to respiratory infections and later invasive streptococcal infections have been well documented. However, few studies have compared rates af gastro-intestinal infections during the pandemic with the previous years. This study aims to compare the number and characteristics of children hospitalized with gastrointestinal infections before the COVID-19 pandemic, to the first strict lockdown in 2020 and to the second, less strict lockdown in 2021. A retrospective review of medical records will be performed, of patients aged 1 month to 5 years admitted with gastroenteritis at the pediatric department at Slagelse Hospital in Denmark over a period from 2017 to 2021.
The primary objective of this study is to analyze smart phone-based Transdermal Optical Imaging (TOI) features to develop a model that can discern hypohydration from euhydration status including 1) a small feasibility study for 24-hour data collection in the general population using passive dehydration or ad libitum fluid intake (GENPOP), 2) an exercise study in moderately active participants in both dehydrated and euhydrated states (EXERCISE). TOI data will be collected alongside standard reference measures of hydration status. This is an exploratory pilot proof of concept study with each subject serving as their own control.
The investigators want to understand the impact of the body losing and gaining water on brain function. Participants will restrict fluids consumed and exercise to lose 5% of body mass. Participants will then be provided fluid equal to the volume lost to consume over 2 hours (recovery). A series of brain function tests will be performed at baseline, following weight loss, and following recovery.
This study will assess the efficacy of Cellular MatrixTM BCT-HA Kit treatment compared to placebo condition on revitalization and skin rejuvenation on the midface. Particular attention will be made to the safety aspects, as well as the histological consequences of treatment.
An epidemic of chronic kidney disease is occurring in laborers who undertake physical work outdoors in hot conditions. The reason for this is largely unknown, but may be related to kidney dysfunction caused by increases in body temperature and dehydration that elicit oxidative stress and inflammation in the renal tubules. The purpose of this study is to determine whether hydration status modifies the development of renal oxidative stress and inflammation.
The purpose of this study is to determine if drinking proprietary water (PW) during a standardized daily plan as compared to distilled water (control) and carbohydrate-electrolyte (CE) drink can improve hydration status over time. Another purpose is to determine if PW, as compared to control and CE, can improve hydration status, perceptual responses, physiological responses, and cognition measures in a heat stressful environment. Healthy, physically active males and females aged 18 to 50y will be recruited for the study. Participants will be randomized into one of three groups: PW, CE, or Control. The participant will be given a daily standardized plan integrating their assigned fluid into daily hydration habits for five days. Participants will provide their first-morning urine sample, keep a daily food log, and answer questions about their perceptions of hydration. After the five days, they will participate in a treadmill exercise protocol within a warm environment (heat chamber). Multiple physiological, perceptual, and cognitive measures will be obtained while participants exercise and then recover.
Dehydration lowers both physical and mental performance if it is severe enough. Performance declines are more pronounced in hot conditions or after prolonged strenuous activity such as exercise. Most individuals drink less than their sweat losses during activity, while some individuals overdrink and develop a sodium deficiency. Water and electrolyte balance must be restored as part of the recovery process after any activity that causes sweating. Plain water causes a decrease in plasma sodium concentration and osmolality, which reduces the desire to drink and increases urine production. Unless the volume ingested exceeds the loss, individuals are in net negative fluid balance throughout the recovery period due to urinary losses. When sodium and potassium are added to rehydration fluids, urine production is reduced in the hours following rehydration. Rehydration is only possible if a volume of fluid equal to or greater than the amount lost through sweat is consumed, together with adequate electrolytes. The test products for this study, TP1 and TP2, are novel hydration beverage formulas. They are an electrolyte drink mixture with five essential vitamins and three times more electrolytes than typical sports beverages. The test products create an osmotic force that permits water to be supplied to the bloodstream sooner in the digestive system by using a specific ratio of sodium, glucose, and potassium. This randomized, placebo-controlled, semi-blind, crossover study will evaluate the effects of the test products on rehydration in healthy adults.
The central hypothesis is that improving hydration through increased water consumption will change the relative abundance of mucolytic bacteria found in the stool. Therefore the specific aims are 1) to quantify intervention effects on fecal microbiota relative abundance and plasma lipopolysaccharide binding protein, 2) observe the effects of the intervention on bowel frequency and signs/symptoms of gastrointestinal stress, and 3) to investigate relations between executive function and hydration status.
The purpose of this study was to determine if rapid changes in hydration status could be determined by urine color expressed in CIE color space
The purpose of this study is to investigate the ability of a wearable bioimpedance sensor to detect mild dehydration in healthy volunteers following the administration of Furosemide. In addition, the study will investigate changes in bioimpedance related to normal variation in tissue hydration (circadian changes, skin thickness, posture, and moderate activity). The study will also provide information on the durability of the sensor.
