Risk Of Kidney Stones In Living Kidney Donors: A Matched Cohort Study, Sonia Thomas Dec 2013

Risk Of Kidney Stones In Living Kidney Donors: A Matched Cohort Study, Sonia Thomas

Electronic Thesis and Dissertation Repository

A kidney stone in a person with one kidney requires urgent attention which may result in surgical and/or hospital attention. We conducted a matched retrospective cohort study to determine if living kidney donors compared to healthy non-donors have a higher risk of: 1) kidney stones with surgical intervention, and 2) hospital encounters for kidney stones. We reviewed and linked information from pre-donation charts to Ontario healthcare databases. We selected healthy non-donors from the general population, matching ten non-donors to every donor, to generate a cohort of 2,019 donors and 20,190 non-donors. There was no difference in the rate of 1) …


Atypical Antipsychotic Drugs And The Risk Of Acute Kidney Injury: A Population-Based Cohort Study, Yoseob Joseph Hwang Jul 2013

Atypical Antipsychotic Drugs And The Risk Of Acute Kidney Injury: A Population-Based Cohort Study, Yoseob Joseph Hwang

Electronic Thesis and Dissertation Repository

Older adults are frequently prescribed atypical antipsychotic drugs and may be at a risk for kidney-related adverse events. This population-based retrospective cohort study examined the 90-day risk of acute kidney injury (AKI) and the potential reasons for AKI in 96,471 matched pairs of older adults who received and who did not receive a new atypical antipsychotic drug prescription from 2003 to 2011 in Ontario. Atypical antipsychotic drug use was associated with a higher risk of hospitalization with AKI (relative risk (RR) 2.06 [95% confidence interval (CI) 1.85–2.29]). The drug use was also associated with potential reasons for AKI including hypotension …


Patency And Complication Rates Of The Arteriovenous Fistula: A Systematic Review, Ahmed A. Al-Jaishi Jul 2013

Patency And Complication Rates Of The Arteriovenous Fistula: A Systematic Review, Ahmed A. Al-Jaishi

Electronic Thesis and Dissertation Repository

Advantages of fistulas, which include long patency and low complication rates, were ascertained over two decades ago and may not apply to the contemporary dialysis population. We conducted a systematic review to summarize the patency and complication rates of fistulas from literature published after 1999. We screened 7,008 citations and 62 articles met our criteria. The risk of primary failure was 27% (95% confidence interval (CI): 23–32%). When primary failures were included, the primary and secondary patency rates were 59% (CI 53–64%) and 66% (CI 58–74%) at one year, respectively. The median rates of infection, ischemic steal syndrome, and thrombosis …
