GRM7, the gene encoding metabotropic glutamate receptor 7 (mGluR7), have been implicated in multiple neuropsychiatric disorders and shown to mediate excitatory synaptic neurotransmitter signaling and plasticity in the mammalian brain. Here we report a 303 kb de novo deletion at band 3p26.1, disrupting five coding exons of GRM7 in a proband with autism spectrum disorder, and hyperactivity.

Intravenous immunoglobulin for preventing infection in preterm and/or low birth weight infants.

Cochrane Database Syst Rev

July 2013

Departments of Paediatrics, Obstetrics and Gynaecology and Institute of Health Policy, Management and Evaluation, University ofToronto, Toronto, Canada.

Background: Nosocomial infections continue to be a significant cause of morbidity and mortality among preterm and/or low birth weight (LBW) infants. Preterm infants are deficient in immunoglobulin G (IgG); therefore, administration of intravenous immunoglobulin (IVIG) may have the potential of preventing or altering the course of nosocomial infections.

Objectives: To use systematic review/meta-analytical techniques to determine whether IVIG administration (compared with placebo or no intervention) to preterm (< 37 weeks' postmenstrual age (PMA) at birth) or LBW (< 2500 g birth weight) infants or both is effective/safe in preventing nosocomial infection.

Intravenous immunoglobulin for suspected or proven infection in neonates.

Cochrane Database Syst Rev

July 2013

Departments of Paediatrics, Obstetrics and Gynaecology and Institute of Health Policy, Management and Evaluation, University ofToronto, Toronto, Canada.

Background: Neonates are at higher risk of infection due to immuno-incompetence. Maternal transport of immunoglobulins to the fetus mainly occurs after 32 weeks' gestation, and endogenous synthesis begins several months after birth. Administration of intravenous immunoglobulin (IVIG) provides immunoglobulin G (IgG) that can bind to cell surface receptors, provide opsonic activity, activate complement, promote antibody-dependent cytotoxicity and improve neutrophilic chemo-luminescence.

Ibuprofen for the treatment of patent ductus arteriosus in preterm and/or low birth weight infants.

Cochrane Database Syst Rev

April 2013

Departments of Paediatrics, Obstetrics and Gynaecology and Institute of Health Policy, Management and Evaluation, University ofToronto, Toronto, Canada.

Background: Indomethacin is used as standard therapy to close a patent ductus arteriosus (PDA) but is associated with reduced blood flow to several organs. Ibuprofen, another cyclo-oxygenase inhibitor, may be as effective as indomethacin with fewer side effects.

Objectives: To determine the efficacy and safety of ibuprofen for closing a PDA in preterm and/or low birth weight infants.

Intrapartum antibiotics for known maternal Group B streptococcal colonization.

Cochrane Database Syst Rev

January 2013

Departments of Paediatrics, Obstetrics and Gynaecology and Institute of Health Policy, Management and Evaluation, University ofToronto, Toronto,

Background: Maternal colonization with group B streptococcus (GBS) during pregnancy increases the risk of neonatal infection by vertical transmission. Administration of intrapartum antibiotic prophylaxis (IAP) during labor has been associated with a reduction in early onset GBS disease (EOGBSD). However, treating all colonized women during labor exposes a large number of women and infants to possible adverse effects without benefit.

Optimal weighting of costs and probabilities in a risky motor decision-making task requires experience.

J Exp Psychol Hum Percept Perform

June 2013

Faculty of Kinesiology and Physical Education, University ofToronto, 55 Harbord St., Toronto, Ontario, Canada.

Previous research has revealed that people choose to aim toward an "optimal" endpoint when faced with a movement task with externally imposed payoffs. This optimal endpoint is modeled based on the magnitude of the payoffs and the probability of hitting the different payoff regions (endpoint variability). Endpoint selection, however, has only been studied after people had experience with the aiming task.

Early erythropoietin for preventing red blood cell transfusion in preterm and/or low birth weight infants.

Cochrane Database Syst Rev

September 2012

Departments of Paediatrics, Obstetrics and Gynaecology and Institute of Health Policy, Management and Evaluation, University ofToronto, Toronto, Canada.

Background: Low plasma levels of erythropoietin (EPO) in preterm infants provide a rationale for the use of EPO to prevent or treat anaemia.

Objectives: To assess the effectiveness and safety of early initiation of EPO in reducing red blood cell (RBC) transfusions in preterm and/or low birth weight infants.

Search Methods: The Cochrane Central Register of Controlled Trials (The Cochrane Library), MEDLINE, EMBASE, CINAHL, abstracts from scientific meetings published in Pediatric Research and reference lists of identified trials and reviews were searched through July 2009.

We used a longitudinal design to investigate the impact of a government policy banning the display of tobacco products at the point of sale. The extent of tobacco promotions in 481 randomly selected stores was documented at 4 points in time (2005-2009). Tobacco promotions were greatly reduced after implementation of the display ban.

Background: In Canada, national health surveys do not usually include questions pertaining to self-perceived oral health. Those that do use ad hoc sets of questions rather than standardized and validated measures of the functional and psychosocial impacts of oral disorders.

Aims: To collect national data on the impacts of oral disorders from a representative sample of Canadian adults and to compare the results with similar national surveys conducted in the United Kingdom and Australia.

Purpose Of Review: This review focuses on studies that help elucidate the optimum approach to posttreatment follow-up of breast cancer patients.

Recent Findings: The re-conceptualization of follow-up under the rubric of survivorship care and the benefit of survivorship care plans, studies on the elements of follow-up care including surveillance mammograms, alternative models of follow-up care including primary care based follow-up, and patterns of care studies that involve population-based samples are discussed. Posttreatment follow-up of breast cancer patients continues to be controversial despite almost two decades of research.

Resolution of glycoproteins by a lectin gel-shift assay.

Anal Biochem

March 2000

Medical Research Council Group in Membrane Biology, Department of Medicine, University ofToronto, Toronto, Ontario, M5S 1A8, Canada.

Gel-shift assays previously described in the literature are based on protein-protein or protein-DNA interactions. We show that carbohydrate-lectin interactions can be successfully used to alter the electrophoretic mobility of glycosylated, but not nonglycosylated, protein species in SDS-polyacrylamide gels. We were able to separate the two closely migrating mono- (95 kDa) and nonglycosylated (92 kDa) forms of a polytopic membrane protein, anion exchanger 1 (AE1), synthesized by cell-free translation or in transfected HEK293 cells.
