Sociodemographic characteristics and clinical features of patients with adult polycystic kidney disease undergoing hemodialysis

Aims:To analyze the socio-demographic and clinical characteristics of patients with adult polycystic kidney disease admitted to hemodialysis services in Northwestern Paraná state,Brazil. Methods: This was an observational, descriptive and retrospective longitudinal study. Medical records of patients with polycystic kidneys who initiated hemodialysis between 1995 and 2012, in four centers that treat patients of the coverage area of the 15th Regional Health Region of Paraná state where analyzed. Results:We found that 10.3% of hemodialysis patients had polycystic kidney disease as a leading cause of stage 5 of chronic kidney disease. The mean age of patients was 54.9±9.4 years (ranging between 27 and 74 years), with equal gender distribution and Caucasian predominance (72.9%). The average age of dialysis initiation was 50±10.2 years. The most common comorbidity was systemic hypertension (66.7%). Liver cyst was the main extra-renal manifestation (10.4%). Twenty-five percent of the patients required renal transplantation, and (22.9%) undergone nephrectomy. The most widely used classes of antihypertensive drugs were β-blockers (41.7%) and drugs that act on the renin-angiotensin system (31.3%), while 56.3% of patients were treated with recombinant human erythropoietin. Conclusions:This is a pioneering epidemiological study in Northwestern Paraná state. We found in this population a sociodemographic and clinical profile of adult polycystic kidney disease similar to that of North America and Europe, probably because the ethnic constitution of the sample was predominantly of Euro-descendants.

Injection of adult mouse mesenchymal stem cells into the developing chick inner ear

This series of experiments attempted to characterize the abilities of stem cells derived from bone marrow and adipose tissue to integrate into the sensory epithelium of the inner ear and to differentiate into hair cells or neural cell types.

Subjective and objective measures of adult bimodal users' listening

Inconsistencies exist between traditional objective measures such as speech recognition and localization, and subjective reports of bimodal benefit. The purpose of this study was to expand the set of objective measures of bimodal benefit to include non-traditional listening tests, and to examine possible correlations between objective measures of auditory perception and subjective satisfaction reports.

Predator Exclosures Enhance Reproductive Success but Increase Adult Mortality of Piping Plovers (Charadrius melodus)

Piping Plovers (Charadrius melodus) are listed as endangered throughout Canada and the United States Great Lakes region. Most attempts to increase their numbers have focused on enhancing reproductive success. Using 22 years of data collected by Parks Canada in Prince Edward Island National Park of Canada, we examined whether predator exclosures installed around Piping Plover nests increased nest success and hatching and fledging success when compared to nests without exclosures. Nests with exclosures were significantly more likely to hatch at least one egg than nests without exclosures, and they hatched a significantly greater number of young. The greater reproductive success observed in exclosed nests is likely due to the increased protection from predators that the exclosures conferred; significantly fewer exclosed nests were depredated than nonexclosed nests. However, significantly more exclosed than nonexclosed nests were abandoned by adults, and they had significantly greater adult mortality. Whether benefits of increased reproductive success from exclosures outweigh costs of increased abandonment and adult mortality remains unknown, but must be considered.
