[EX Q]: With advances in medicine, the subjective assessment of patients on hemodialysis regarding their quality of life (QOL) is gaining importance. Clinicians cannot rely solely on objective markers, such as the rates of complications and mortality, when evaluating responses to dialysis. In clinical settings, laboratory values are used as measures of patients' health. However, the relationship between clinical laboratory values and QOL has not been elucidated yet. Therefore, the present study aimed to define the relationship of laboratory values and patient attributes to the QOL of outpatients on hemodialysis in order to obtain basic data for reevaluating nursing support for patients on hemodialysis in the future.", 'The participants were 44 outpatients receiving hemodialysis at Hospital B. The QOL was surveyed using a self-administered questionnaire, the Kidney Disease Quality of Life Short Form. The following patient attributes and laboratory values were taken from the medical records: age; sex; primary disease; number of years on hemodialysis; complications; number of hours of hemodialysis per session; percentage weight gain; cardiothoracic ratio; blood pressure; hematocrit; and the serum levels of albumin, potassium, phosphorus, and calcium.', 'The serum potassium level significantly affected mental health, social functioning, symptoms, and the effect of kidney disease, with the 3.5-5.0 mEq/L target range group scoring higher than the > or =5.1 mEq/L group.

[EX Q]: We sought to determine the association between low caregiver health literacy and child emergency department (ED) use, both the number and urgency of ED visits.', 'This year long cross-sectional study utilized the Newest Vital Sign questionnaire to measure the health literacy of caregivers accompanying children to a pediatric ED. Prior ED visits were extracted from a regional database. ED visit urgency was classified by resources utilized during the index ED visit. Regression analyses were used to model 2 outcomes-prior ED visits and ED visit urgency-stratified by chronic illness. Analyses were weighted by triage level.', 'Overall, 503 caregivers completed the study; 55% demonstrated low health literacy. Children of caregivers with low health literacy had more prior ED visits (adjusted incidence rate ratio 1.5; 95% confidence interval 1.2, 1.8) and increased odds of a nonurgent index ED visit (adjusted odds ratio 2.4; 95% confidence interval 1.3, 4.4). Among children without chronic illness, low caregiver health literacy was associated with an increased proportion of nonurgent index ED visits (48% vs. 22%; adjusted odds ratio 3.2; 1.8, 5.7).

[EX Q]: To examine the association between injection cocaine use, hepatitis C virus (HCV) infection, and chronic renal impairment (CRI).', 'Prospective observational cohort study of HIV-HCV coinfected patients.', 'Data from 1129 participants in the Canadian Co-Infection Cohort with baseline and follow-up serum creatinine measurements between 2003 and 2014 were analyzed. Prevalent and incident cohorts were created to examine the association between self-reported past, current, and cumulative cocaine use and chronic HCV with CRI. CRI was defined as an estimated glomerular filtration rate below 70\u200aml/min per 1.73\u200am. Multivariate logistic regression was used to calculate odds ratios, and discrete-time proportional-hazards models were used to calculate hazard ratios for cocaine use, in the two respective cohorts, adjusted for HCV RNA and important demographic, HIV disease stage, and comorbidity confounders.', 'Eighty-seven participants (8%) had prevalent CRI. Past injection cocaine use was associated with a two-fold greater risk of prevalent CRI [odds ratio 2.03, 95% confidence interval (CI) 0.96, 4.32]. During follow-up, 126 of 1061 participants (12%) developed incident CRI (31 per 1000 person-years). Compared to nonusers, heavy (≥ 3\u200adays/week) and frequent injection cocaine users (≥75% of follow-up time) experienced more rapid progression to CRI (hazard ratio 2.65, 95% CI 1.35, 5.21; and hazard ratio 1.82, 95% CI 1.07, 3.07, respectively). There was no association between chronic HCV and CRI in either cohort.
