Background Cardiopulmonary failure refractory to medical management after moderate-to-high-risk congenital cardiac surgery may necessitate mechanical support with veno-arterial extracorporeal membrane oxygenation (ECMO). On the extreme, ECMO can also be initiated in setting of arrest (extracorporeal cardiopulmonary resuscitation, ECPR) unresponsive conventional resuscitative measures. Methods This was a single-center retrospective cohort study patients ( n = 510) aged &lt;3 years old who...
Serotyping of
Detection of pneumococcal carriage by multiple co-colonizing serotypes is important in assessing the benefits conjugate vaccine (PCV). Various methods differing sensitivity, cost and technical complexity have been employed to detect pneumococcus respiratory specimens. We developed an algorithmic method all known that preserves relative abundance specific using Quellung-guided molecular techniques. The involves culturing swabs followed serotyping 100 colonies either capsular (10 colonies) or...
Hospitalized medical patients cared for by female physicians may have decreased mortality rates compared with of male physicians. However, this association has yet to be assessed outside the US, and little is known about factors that explain difference.To determine whether mortality, other hospital outcomes, processes care differed between physicians.This retrospective cross-sectional study included admitted general wards at 7 hospitals in Ontario, Canada, April 1, 2010, October 31, 2017....
Homicides are a major problem in Brazil. Drugs and arms trafficking, land conflicts three of the many factors driving homicide rates Understanding long-term spatiotemporal trends social structural associated with homicides Brazil would be useful for designing policies aimed at reducing rates.We obtained data from 2000 to 2014 Ministry Health (MOH) Mortality Information System sociodemographic Institute Geography Statistics (IBGE). First, we quantified rate change municipality state levels....
Changes to endoscopy service availability during the COVID-19 pandemic may have affected management of upper gastrointestinal bleeding (UGIB). The aim this study was describe impact on UGIB outcomes in Toronto area Canada.We described all adults admitted general medicine wards or intensive care units at six hospitals and Mississauga, Canada, with first wave (March 1 June 30, 2020) compared them a historical cohort 2018 2019). We clinical (in-hospital mortality, length stay, 30-day...
Background: The impact of SARS-CoV-2 on neonates remains largely unknown in low- and middle-income countries (LMICs). We provide an epidemiologic clinical report infections hospitalized Bangladesh. Methods: Outborn admitted to Dhaka Shishu Hospital, a tertiary-care referral hospital, between 29 March 1 July were screened for SARS-CoV-2. reviewed data, including chest radiograph laboratory reports, conducted genome sequencing. Patients followed-up 27–75 days. A subset caregivers was also...
Multiple survey reports suggest that alcohol use has increased in Canada during the COVID-19 pandemic. However, less is known about how per capita sales, which predict population-level use, have changed and whether changes sales differ from of other products due to pandemic factors.We obtained monthly retail data by industry Statistics Canada, for six largest provinces (containing 93% national population), between January 2010 November 2020, representing time before 9 months after start...

ABSTRACT The COVID-19 pandemic exhibits stark social inequities in infection and mortality outcomes. We investigated neighborhood-level across cities the US Canada for cumulative case rates (46 cities), death (12 testing test positivity using measures that characterize gradients by race/ethnicity, socioeconomic composition, or both jointly. found consistent evidence of case, rates, with most privileged neighborhoods having lowest but no meaningful variation magnitude between cities....
ABSTRACT Serotyping of Streptococcus pneumoniae is a critical tool in the surveillance pathogen and development evaluation vaccines. Whole-genome DNA sequencing analysis becoming increasingly common an effective method for pneumococcal serotype identification pure isolates. However, because complexities capsular loci, current software requires samples to be (or nearly pure) only contain single serotype. We introduce new called SeroCall, which can identify quantitate serotypes present...
Reducing laboratory test overuse is important for high quality, patient-centred care. Identifying priorities to reduce low value testing remains a challenge.To develop simple, data-driven approach identify potential sources of by combining the total cost, proportion abnormal results and physician-level variation in use tests.A multicentre, retrospective study at three academic hospitals Toronto, Canada. All general internal medicine (GIM) hospitalisations between 1 April 2010 31 October...
Abstract Background Current scores for predicting sepsis outcomes are limited by generalizability, complexity, and electronic medical record (EMR) integration. Here, we validate a simple EMR-based score in large multi-centre cohort. Methods A record-based predictor of illness severity (SEPSIS) was developed (4 additive lab-based predictors: Creatinine, Bilirubin, Platelet Count, Lactate) using retrospective cohort study patients admitted to internal medicine services from April 2010 - March...
