Abstract:
... Survivors of critical illness requiring prolonged mechanical ventilation (PMV) are predisposed to malnutrition, muscle wasting, and weakness. There is a lack of data regarding nutrition adequacy among these patients, and although nitrogen balance has been studied as a marker of adequate protein intake in healthy individuals and acutely critically ill patients, it has not been well studied in criti ...

Abstract:
... Urine and fecal excretions from cattle contribute to global nitrogen (N) emissions. The milk urea nitrogen (MUN) concentration in dairy cows is positively correlated with urinary urea N (UUN) emissions, and both decline with the reduction in crude protein intake. However, MUN concentration may differ between individual cows despite feeding the same ration. Thus, we hypothesized that due to differe ...

Abstract:
... In this study, we hypothesized that spot urine can be used to predict protein intake at both group and individual levels. Participants (n = 369) of this study were recruited from all 47 prefectures in Japan. Sex-specific formulas were developed based on the ratio of urea nitrogen to creatinine concentration obtained from 3 spot urine samples. Validity of the formulas was examined against two 24-ho ...

Abstract:
... The optimal amount of protein intake in critically ill patients is uncertain. In this post hoc analysis of the PermiT (Permissive Underfeeding vs. Target Enteral Feeding in Adult Critically Ill Patients) trial, we tested the hypothesis that higher total protein intake was associated with lower 90-d mortality and improved protein biomarkers in critically ill patients. In this post hoc analysis of t ...

Abstract:
... Dietary intake can promote good health including blood pressure control from low sodium intake, slow progression of chronic kidney disease (CKD) from low protein diet. Counseling how to control amount of diet may be unpractical unless there is objective information of consumed nutrient. A 24-hour urine collection can provide information regarding the amount of intake nutrient. We present a case of ...

The aim of this study was to determine the role of protein intake on proteinuria in chronic kidney disease (CKD), as it is presently not conclusive.This is a subanalysis of data from an open-label, case-controlled, randomized clinical trial on education about low-salt diets (NCT01552954). We estimated the urine excretion rate of parameters in a day, adjusted by using the equation for estimating ur ...

Renal injury appears around 10 years of age and requires dialysis by the age of 30 years. Low protein intake attenuated renal damage in animal experimental models, uninephrectomized patients, and kidney transplant donors and recipients. Low salt intake facilitates blood press ...
