Dietary Intake of Proteins and Calories Is Inversely Associated With The Oxidation State of Plasma Thiols in End-Stage Renal Disease Patients.

Objectives: Oxidative stress contributes to the pathogenesis of protein-energy wasting in maintenance hemodialysis (MHD) patients, but knowledge of specific effectors and mechanisms remains fragmented. Aim of the study was to define whether and how food intake is involved in the causal relationship between oxidative stress and protein-energy wasting.

Methods: Seventy-one adult MHD patients and 24 healthy subjects (control) were studied cross-sectionally with analyses of diet record and of oxidative stress, as measured by a battery of plasma thiols including the protein sulfhydryl (-SH) group (PSH) levels (a marker of total protein-SH reducing capacity), the protein thiolation index (PTI, the ratio between disulfide, i.

Comparison of Nutrition Profile and Diet Record Between Veteran and Nonveteran End-Stage Renal Disease Patients Receiving Hemodialysis in Veterans Affairs and Community Clinics in Metropolitan South-Central Texas.

Background: U.S. military veterans have high rates of chronic disease and social disadvantage, which are risk factors for protein-energy wasting (PEW).

Glutathione redox potential is low and glutathionylated and cysteinylated hemoglobin levels are elevated in maintenance hemodialysis patients.

Glutathione (GSH), the most abundant intracellular low molecular mass thiol, protects cells from oxidative damage and regulates their function. Available information is inconsistent regarding levels of GSH and its disulfide (GSSG) in maintenance hemodialysis patients (HD). In addition, very limited data are available in HD about the relationship of GSH and GSSG with other measures of thiol metabolism and with the clinical profile.

Maternal acculturation: could it impact oral health practices of mexican-american mothers and their children?

A mother's cultural beliefs can affect her infant's health, but the influence of acculturation of Mexican-American women on their young children's oral health is unknown. The authors hypothesized that maternal acculturation impacts very young children's oral health practices favoring, in particular, the mothers who are more Anglo-oriented. A convenience sample of 204 predominantly Mexican-American women attending the Women, Infants, and Children Clinic in San Antonio, Texas, completed the Knowledge, Attitudes, Beliefs, Social Support, and Self-Efficacy of Oral Health (KASE-OH) and Acculturation Questionnaires.
