25(OH)D deficiency has been associated with significantly worse physical performance in individuals normal renal function. We examined the function, muscle strength and balance age- gender-matched 25 Stage 3 - 4 CKD patients 47 5 on peritoneal dialysis (PD) vitamin D by objective methods evaluated effect of replacement tests: "timed up go" (TUG) test, gait velocity timed chair stand stair climb dynamic tests (TUG postural stability test), static test (functional reach test) these two groups....

♦Older in-center hemodialysis patients have a high burden of functional disability. However, little is known about on home chronic peritoneal dialysis (PD). As opting for are expected to play greater role in their own care, we hypothesized that relatively low number PD would require help with basic self-care tasks (ADL) and instrumental activities daily living (IADL). ♦We used cross-sectional study design measure the proportion aged 65 years older undergoing outpatient who needed day-to-day...

More than 40% of elderly hemodialysis patients experience one or more accidental falls within a 1-year period. Such are associated with higher mortality. The objectives this study were to assess whether also common in established on peritoneal dialysis and evaluate if have risk mortality who do not fall.Using prospective cohort design, ages ≥ 65 years chronic from April 2002 2003 at the University Health Network recruited. Patients followed biweekly, occurring first 15 months recorded....

Data about the morphological changes in peripheral blood smears during COVID-19 infection and their clinical severity association are limited. We aimed to examine characteristics of cells detected pathological rate and/or appearance whether these findings related course by evaluating smear at time diagnosis patients.Clinical features, laboratory data, fifty patients diagnosed with PCR was evaluated diagnosis. Peripheral samples were compared age sex-matched 30 healthy controls. Pictures...

♦ Background Accidental falls are common in the hemodialysis (HD) population. The high fall rate has been attributed to a combination of aging, kidney disease-related morbidity, and HD treatment-related hazards. We hypothesized that patients maintained on peritoneal dialysis (PD) would have fewer than those chronic HD. objective this study was compare risk between cohorts elderly PD, using prospective data from large academic facility. Methods Patients aged 65 years or over in-hospital PD at...

An increase of brain natriuretic peptide (BNP) levels is commonly observed in patients on dialysis. Increased circulating BNP are related to future cardiac events and associated with shorter survival chronic hemodialysis (HD). During the first 1 or 2 years dialysis, peritoneal dialysis (PD) have been shown an improvement left ventricular hypertrophy, blood pressure, volume status. This study compares status PD HD without cardiovascular disease for less than 36 months. The correlation between...

Background: In patients with heart failure plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) levels are correlated to urine neutrophil gelatinase-associated lipocalin (NGAL) levels. We prospectively evaluated the relationship among glomerular filtration rate (eGFR), albumin-to-creatinine ratio (ACR), and serum NGAL NT-proBNP in 20 type II diabetic macroalbuminuria at 4-month intervals. Results: Compared age, gender-matched healthy controls, had higher NGAL, lower eGFR. The eGFR of...
