Page 1 of 47 Identifying genetic causes of congenital and developmental disorders in adults Supervisor Name: Anne Bassett Hospital/Research Institution: Centre for Addiction and Mental Health Email: anne.bassett@utoronto.ca Department: Psychiatry Brief Project Description We are studying major developmental diseases, including congenital cardiac disease and schizophrenia. Together with colleagues at the University Health Network, Hospital for Sick Children and other international institutions, we are clinically screening patients with these conditions to determine those most likely to have genetic syndromes and/or other de novo or inherited forms of these diseases. Using state-of-the-art molecular genetic methods we are identifying patients with structural (deletions or duplications) and other mutations and studying inheritance patterns and clinical expression. We directly translate clinically significant results to help patients and their families with anticipatory care and genetic counselling. This is clinical and statistical research (not bench lab research - this is with our colleagues) at the forefront of molecular medicine Page 2 of 47 Which protocol identifies retinal toxicity associated with an antiepileptic drug used in early childhood Supervisor Name: Carol Westall Hospital/Research Institution: The Hospital for Sick Children Email: Carol.westall@sickkids.ca Department: Ophthalmology and Vision Science Brief Project Description: Infants with seizure disorders are treated with the anti-epileptic drug vigabatrin. About 20% of treated children develop retinal toxicity. This project will compare the predictive ability of the standard clinical electroretinogram (ERG) and a structural assessment tool called ocular cohehence tomography (OCT). Over the summer it is expected that 20 infants will be assessed clinically including electroretinogram testing and retinal examination. The summer student will work with a coordinator, physicians, electrophysiologists and technical staff. Appointments will be coordinated and the student will collect clinical and study data; will evaluate data and conduct statistical assessment using a Cox regression model with time dependent covariates. The hazard ratio associated with the measurements on the risk of retinal damage in infants and young children will be estimated for both test paradigms. The results of this assessment are expected to help determine the optimal tool to assess retinal toxicity associated with the antiepileptic drug vigabatrin. Page 3 of 47 Genome-based personalized therapy for prostate cancer Supervisor Name: Dr. Paul C. Boutros Hospital/Research Institution: Ontario Institute for Cancer Research & University of Toronto Email: Paul.Boutros@oicr.on.ca Brief Project Description: The Canadian Prostate Cancer Genome Network (CPC-GENE) is a coordinated multi-centre effort to identify prognostic and predictive biomarkers for intermediate-risk prostate cancer patients. Approximately 1 in 7 Canadian men will be diagnosed with prostate cancer over the course of their lifetime. About a third of these are diagnosed with intermediate-risk disease – as determined by the clinical variables of T-category and pre-treatment PSA and the pathological grade (Gleason score). Despite best-treatment with precision radiotherapy or surgery, about 40% of patients will suffer relapse. CPC-GENE aims to use whole-genome sequencing, RNA-sequencing and epigenetic profiling to identify those patients who suffer relapse at the time of initial therapy. This project, as part of CPC-GENE, involves working with the resulting data to develop these clinical-tools. This includes primarily clinical, biostatistical and bioinformatic data-analysis, and working to link the clinical data to the genomic information on a per-patient basis to create a portrait of disease risk and progression. The applicant will be directly supervised by a computational biologist, but will work very closely with the study pathologist and overall-lead (a radiation oncologist), and thus is designed to give a strong sense of the interactions of a large translational research program. Page 4 of 47 Magnetic Occult Lesion Localization and Imaging (MOLLI) for Non-Palpable Breast Cancers Supervisor Name: Nicole Look Hong / Anath Ravi Hospital/Research Institution: Sunnybrook Research Institute Email: nicole.lookhong@sunnybrook.ca Brief Project Description Purpose: The goal of this project is to evaluate an alternative to wire localization for surgical resection of nonpalpable breast lesions: Magnetic Occult Lesion Localization and Imaging (MOLLI). This novel approach to tumour localization, developed at Sunnybrook Odette Cancer Centre, involves implanting non-radioactive magnetic seed(s) under radiographic guidance to clearly define the center and extent of tumour. Seeds are completely contained within the breast, do not pose a risk of dislodgement or movement-related discomfort, and can be implanted several days in advance. any need for radiation safety precautions. Seeds are also non-radioactive, eliminating Using a novel and user-friendly detection system, the surgeon can precisely identify the location of seeds, and perform skin incisions and resection achieving both optimal cosmetic result and oncologic outcomes. Methodology: Pre-clinical validation studies will be performed on anthropomorphic phantoms to determine whether MOLLI can replace wire localization. Tests will include quantifying the sensitivity and resolution of the MOLLI system to ensure accurate detection of the magnetic seeds under clinically representative scenarios. These phantom studies will form the basis of a pre-clinical validation study a pilot series of localizations in breast cancer patients with small non-palpable tumors will be completed to ascertain feasibility, safety, patient acceptability, and satisfaction of all involved clinicians. Objectives: At the end of this study it is expected that the student contribute to a manuscript that characterizes the performance of the MOLLI system in phantom geometries. These results will also be presented at an international conference for rapid knowledge translation into the surgical oncology community. Additionally, based on the outcomes from the preliminary pre-clinical studies it is expected that the student may also participate in filing for research ethics board approval for subsequent pilot series clinical trials. Page 5 of 47 Endo-bronchial ultrasound guided trans-bronchial biopsy; the impact of limited resources on diagnostic accuracy Supervisor Name: Abdollah Behzadi Hospital/Research Institution: Credit Valley Hospital Email: abdollah.behzadi@trilliumhealthpartners.ca Brief Project Description Endo-bronchial ultrasound is a relatively new technology that is increasingly used to make pathological diagnosis of mediastinal abnormalities. Given the high cost of the equipment and resources that this technology requires, the wide adaptation of this procedure, which results in lesser surgical procedures on affected patients, has been hampered. This is a retrospective chart review study of approximately 180 patients who underwent this procedure over a 2 year period in a university-affiliated community hospital. The goal of this project is to identify a patient cohort whose biopsy results provide accurate and actionable clinical information hence avoiding the procedure in low yield situations. the With the help of supervisor, the student is responsible to develop an understanding of indications for this procedure, write a proposal, collect clinical data, perform statistical analysis, write the initial manuscript, and present the findings in a scientific conference. The student-candidate should have interest in outcome research, background knowledge in statistics, and drive to work independently. Page 6 of 47 The ABCS Trial (Anesthesia for Breast Cancer Surgery): A Two-center Randomized Controlled Comparison of the Impact of General Anesthesia with and without Thoracic Paravertebral Blocks on the Three-month Incidence of Chronic Neuropathic Pain in Women Undergoing Ambulatory Breast Tumor Resection Supervisor Name: Faraj Abdallah Hospital/Research Institution: St. Michael’s Hospital Email: abdallahf@smh.ca Brief Project Description People with breast cancer now live much longer because of better treatments. However, almost 60% of women who have successful breast cancer operations then develop long-term pain. This pain is makes it very hard for these women to sleep, work, interact with family, and carry out their normal daily life. If we can find better ways to stop this pain from happening, women will be able to live a better and pain-free life after their breast cancer surgery. Thoracic paravertebral block (PVB) is a method for using local anesthetics (drugs that ‘numb’ the nerves) to freeze or ‘block’ the nerves around the breast. Some small older studies suggest that using these nerve blocks before surgery can help prevent long-term pain. However, we cannot be certain that these small studies are correct because they have many problems. We therefore want to do a large study to find out if nerve blocks before breast cancer surgery can prevent long-term pain and improve women’s quality of life. In our study, women undergoing breast cancer surgery will be randomly chosen to have either the nerve block or no block before surgery. We will then follow them for 3 months to see whether women who receive the nerve block are less likely to develop long-term pain, and more likely to go back to a good quality of life. We hope that our study will help women survive longer, and also better, after a diagnosis of breast cancer. Page 7 of 47 The INFerence from Observational Reseach Methods (INFORM) Study Supervisor Name: David R. Urbach Hospital/Research Institution: Toronto General Research Institute Division of Support, Systems and Outcomes Email: david.urbach@uhn.ca Brief Project Description As part of a larger project with the overarching aim of developing methods to properly interpret nonrandomized studies of clinical interventions, we are seeking students to undertake components of the research, including: conducting systematic reviews, developing analytic procedures to measure bias in non-randomized studies, co-develop an interactive tool to “adjust” study findings to account for bias, and write a monograph/short book on the problem of bias in health research, how it impacts our understanding of research findings, and how it can be addressed. Students will take “ownership” over their parts of the research program, and will work collaboratively with the larger research team. Research activities will be carried out in the Division of Support, Systems and Outcomes at the Toronto General Hospital Research Institute. Students are provided excellent resources, including modern workstations in a collaborative and interactive research environment, weekly lab meetings, weekly health services research rounds at the Research Institute, and close supervision by their supervisor and the research team. Page 8 of 47 Clinical predictors of outcomes in patients with granulomatosis with polyangiitis with nodular lung involvemnet Supervisor Name: Christian Pagnoux Hospital/Research Institution: Mount Sinai Hospital Email: cpagnoux@mtsinai.on.ca Brief Project Description GPA (Wegener’s) is a rare systemic necrotizing granulomatous vasculitis, associated with anti-neutrophil cytoplasm antibodies (ANCA). Disease onset can occur at any age, most commonly about 40 to 50 years. The main target organs or systems are the upper respiratory tract (erosive rhinitis and sinusitis, saddlenose deformity), lungs (nodules, alveolar hemorrhage) and/or kidney. Biopsy of an affected organ can support the diagnosis, as can detection in serum of cANCA by immunofluorescence and proteinase 3 (PR3) specificity. Current therapy, based on a staged induction–maintenance strategy, can achieve remission in most patients, but relapses are very common, occurring in up to 50% of the patients at 5 years post-diagnosis. Already identified predictors of relapse include PR3-ANCA, lung disease and ENT manifestations. Lungs are involved in 70–100% of patients, with clinical manifestations ranging from mild cough, dyspnea to acute and massive alveolar hemorrhage. Lung nodules are among the most characteristic signs, detected in 40% to 66% of patients; nodules are unilateral or bilateral, single or multiple, measuring 0.5 to 10 cm in diameter, and excavated in half of cases. Whether the presence of excavated nodules, which can be frightening to inexperienced physicians, have poorer prognostic values or not, compared to only plain nodules, in term of treatment response or relapse risk is unknown. The aim of this study is to analyze and compare the characteristics, treatment and outcomes of a cohort of patients with GPA and lung nodules, excavated or not, at the time of disease flares. Study patients will be those followed in the Toronto and Hamilton vasculitis clinics (around 250). Their data will be entered into a recently and already developed and functional database, in order to facilitate this analysis for this study and, perhaps, lead to other similar studies. Page 9 of 47 CLEAN Meds: Carefully seLected and Easily Accessible at No charge Medications Supervisor Name: Nav Persaud Hospital/Research Institution: St. Michael’s Hospital / Keenan Research Centre of the Li Ka Shing Knowledge Institute Email: nav.persaud@utoronto.ca Brief Project Description Background Access to appropriate medications is an important determinant of health. Barriers to Canadians accessing appropriate life-saving or enhancing medications include costs, inappropriate prescribing, lack of healthcare integration and inability to physically obtain medications. Lists of carefully selected medications in the United Kingdom, managed care settings in the United States, and in Sweden have reduced healthcare expenditures and harmonized prescribing behaviors. Providing free medications by mail is expected to increase medication adherence based on clinical trials and observational studies in other countries. Study Objectives We are determining the effects of providing carefully selected essential medications at no charge via a centralized dispensing program on health outcomes and costs. This will be accomplished by fulfilling three objectives: 1. Develop a Canadian list of essential primary care medications 2. Use current Canadian prescribing data to estimate effects on patient care and societal health care expenditure of substituting currently prescribed medications with essential medications. 3. Determine the acceptability and effects of an integrated pharmacist-prescriber model of no charge essential medication dispensing. Student Role Students may have the opportunity to design and perform literature reviews, perform prescribing data analyses, develop and present poster/seminar presentations, interview study participants and/or contribute to protocol, report and manuscript writing. Page 10 of 47 Predictors of success and outcomes for men in chronic, non-obstructive urinary retention treated with sacral neuromodulation Supervisor Name: Girish Kulkarni / Dean Elterman Hospital/Research Institution: PMCC / UHN Email: dean.elterman@uhn.ca Brief Project Description As men age, their prostate glands grow which may lead to blockage of urinary flow. Over time, the muscle of the bladder may become stretched out from squeezing against the blockage and eventually lose its ability to squeeze out urine. A surgery may be performed to open up the channel of the prostate through which urine flows, however, many men will remain unable to void (retention) despite this procedure, as the bladder muscle is too weak. These men will have to insert a tube (catheter) several times a day to empty their bladder. There is a technology, called sacral neuromodulation, which acts like a bladder pacemaker. Just like a heart pacemaker, but implanted under the skin of the lower back, it has a battery and wire that send a gentle electrical signal to the nerves controlling the bladder, which corrects certain abnormal conditions. It is approved to treat overactive bladder, urinary leakage, and retention. However, no previous research has looked exclusively at men with retention using a catheter, as most studies had >90% female participants. As only one of two physicians in Ontario performing this procedure, my research will study predictors of success and outcomes for men in chronic urinary retention treated with sacral neuromodulation. The goal of my study will be to show that the bladder pacemaker can lead this group of men to urinate spontaneously and not require the use of a catheter any longer. Page 11 of 47 Taxonomy of adverse events in critical care transport: Definitions derivation and taxonomy Supervisor Name: Russell MacDonald Hospital/Research Institution: Sunnybrook Health Sciences Centre / Ornge Transport Medicine Email: rmacdonald@ornge.ca Brief Project Description The Institute of Medicine recommends development of taxonomy to standardize error reporting and analysis. Despite the recommendation, many health care settings have not adopted a taxonomy or common terminology. This prevents meaningful generation of new knowledge and improvement in patient safety. Ornge is Ontario’s air and land critical care transport program. It has developed a taxonomy to collect, categorize and analyze adverse events and near-misses in the air and land critical care transport setting. Two items remain: a) derive and standardize terms and definitions for terms used in the taxonomy and b) utilize the taxonomy and its definitions to categorize events reported to coordinator and investigations officer, all under the direct supervision of the program’s Medical Director. This project is well suited to students interested in a future career path in medicine that includes quality care processes, safety, and/or aviation. While experience is not mandatory, the ideal candidate will have some experience in literature searches and chart review, have solid communication and computer skills, and can function well in an interdisciplinary work setting. This summer project can be funded from an existing external grant, and would not be dependent on the student obtaining funding from the CREMS program or other sources. Page 12 of 47 Anesthesia Practices for Laser Therapy in a Pediatric Population Supervisor Name: Joel Fish Hospital/Research Institution: Hospital for Sick Children Email: joel.fish@sickkids.ca Brief Project Description Laser therapy is the newest form of scar modulation available for burn injured patients. At present, the Hospital for Sick Children (SickKids) is fortunate to be the only pediatric center offering this method of scar treatment in Canada. Since its introduction in January 2014, we have treated over 100 patients with pulsed dye and/or CO2 laser therapy. In order to provide laser therapy, children require sedation so that the procedure can be carried out safely. Thus, we would like to conduct a retrospective review of our current anesthesia approach for this procedure. We are particularly interested in examining specific factors such as the type of anesthetic used, dosage, complications, etc. The results of this study are necessary in order to help us optimize treatments and learn more about our ongoing anesthesia practices. At present, there is no published data regarding anesthesia and laser therapy in the literature. Thus, the student who undertakes this study will contribute to a novel area. A student who is detailoriented and highly independent would be an ideal candidate to complete this project. - NOTE: Please list the Research Coordinator for the Burn Program at SickKids as the contact person for this project.

Despite possessing similar clinicopathological features, some patients are at high risk of developing local and/or distant recurrence and dying of their cancer, whereas many others will have clinically insignificant disease and will not benefit from adjuvant radiotherapy. Determining which patients are unlikely to derive a therapeutic benefit from RT will prevent overtreatment, removing the burden of unnecessary therapy and side-effects from patients and healthcare systems. Conversely, the ability to accurately identify which patients harbor residual aggressive disease requiring more intensive therapy (i.e., dose intensification or early integration of systemic therapies) could improve patient outcomes. Recent studies indicate that circulating microRNAs are useful as non-invasive biomarkers for different cancers, including PCa. miRNAs are secreted from cancer cells into body fluids such as blood and urine within exosomes. Exosomes are small cell-derived extracellular vesicles actively shed by tumor cells, and contain tumor miRNAs which can exert biological effects in a paracrine manner on normal and cancer cells. Recently, exosomal miRNAs have been attracting major interest as potential diagnostic, prognostic, or even therapeutic biomarkers in urologic malignancies. We believe that exosomal-derived miRNA expression profiling will help to: 1) prognosticate long-term prostate cancer behavior, and 2) predict which therapy could provide the best chance of disease control with acceptable toxicity. This project will involve isolation of exosome-derived microRNA from radical prostatectomy patients, and real-time PCR quantification of a panel of microRNA known to have prognostic significance. Page 14 of 47 Improving survivorship for testicular cancer patients at Princess Margaret Cancer Centre Supervisor Name: Robert Hamilton Hospital/Research Institution: Princess Margaret Cancer Centre Email: rob.hamilton@uhn.ca Brief Project Description Testicular cancer predominantly affects young men age 15-35. Fortunately, the cure rate is very high. Many present with Stage I disease and the only treatment they require is removal of the affected testicle (orchiectomy) followed by close monitoring. However, a significant proportion present with more advanced disease and require further surgery or chemotherapy in addition to an orchiectomy. The treatments, even if only orchiectomy, can affect sexual, reproductive, physical and emotional health. At Princess Margaret Cancer Centre, we have a multidisciplinary testicular cancer clinic and we see the largest volume of testis cancer in Canada. Our current research interests include improving quality of life for survivors of testicular cancer. There are a number of research opportunities a prospective student could choose in our active research group and the summer experience could be molded to suit their wishes. Three projects to consider include: 1) Quantifying prevalence and severity of hypogonadism among men after orchiectomy. Androgen and gonadotropin levels have been collected prospectively in our clinic since 2005 but have yet been analyzed. 2) Creating an application (e.g. iPAD) that serves as a decision aid for men recommended to undergo retroperitoneal lymphadenectomy (RPLND) for metastatic testis cancer. There is a need to better explain the nature of the surgery and potential complications in a dynamic way that can minimize decisional regret as a survivor. 3) Surveying men about uptake of testicular prosthesis insertion at the time of orchiectomy to explore barriers and needs. The aim would be to learn more about the patient and physician factors determining choice of prosthesis to address barriers. Students will be fully integrated within the urologic oncology group at Princess Margaret and will be invited to attend our research rounds, our multidisciplinary tumour rounds, urology rounds, renal tumour board rounds and our testicular cancer research group rounds. Page 15 of 47 Knee Osteoarthritis Quality Improvement Project Supervisor Name: Noah Ivers Hospital/Research Institution: Women’s College Hospital Email: noah.ivers@wchospital.ca Brief Project Description Osteoarthritis (OA) is one of the most common chronic diseases in Canada; affecting 10% of the total population (3% more women than men). With such a large disease burden, it is important that physicians caring for these individuals are aware of, and utilizing all available management strategies. This pilot study will audit a group of patients with a confirmed diagnosis of knee OA and determine their individual quality of care. The gaps in care will be identified and presented to their physicians along with evidencebased recommendations to improve management. We will assess the impact of this audit and intervention using validated OA outcomes. Although the avenues of OA management are well known, evidence-based solutions are not always put into practice. By providing information to physicians about sub-optimal patient care linked to evidencebased solutions, this project hopes to close some of the OA care gaps. In using validated questionnaires as outcome measures, as well as patient and physician feedback, we can assess the necessity and effectiveness of this audit and feedback intervention. By connecting patients with services of which they are in need, we will see improvement, not only in the satisfaction with their OA care, but also in disease measures. We will pilot collecting patient-reported outcome measures using Tablets in the waiting room. Information patients provide will be directly linked to fields in their electronic medical record. The medical student will participate in analyzing and summarizing the project data, develop the feedback reports to family physicians, and assist with manuscript development and PowerPoint slide decks. They will also have the opportunity to work with clinical team members, (e.g., rheumatologist, family physician, and allied care providers) involved in providing care to patients with OA to better understand the patient perspective on how health services for patients with this condition can be improved. Page 16 of 47 Relationship between neurochemical and functional MRI measures in Substance Use Disorder Supervisor Name: Doris Payer Hospital/Research Institution: Centre for Addiction and Mental Health Email: doris.payer@camh.ca Brief Project Description The summer project will be part of a rich MRI research program investigating brain function, structure, and neurochemistry in clinical samples with substance use disorders (SUD), with a focus on opioid, cocaine, alcohol, or nicotine dependence. MRI measures include: functional activation during craving, emotion, and cognitive tasks (fMRI); resting-state activity to be analyzed for network-wide functional connectivity; regional cerebral blood flow; biochemistry (GABA/glutamate concentrations and neurometabolites); and tissue microstructure. The aim of the study is to characterize the relationship of biochemical alterations to functional abnormalities commonly observed in SUD. Analyses will test for these relationships, compare measures to healthy control samples, and investigate longitudinal changes with abstinence or treatment. The project may also relate MRI measures to outcomes from the lab’s PET imaging program, such as dopamine receptor availability in Rx opiate dependence. Page 17 of 47 Feasibility of remote administration of the Fundamentals of Laparoscopic Surgery (FLS) skills test using Google Glass Supervisor Name: Allan Okrainec Hospital/Research Institution: Temetry/Change Telesimulation Centre / Toronto Western Hospital Email: allan.okrainec@uhn.ca Brief Project Description The most well-known curriculum for laparoscopic surgery training is the Fundamentals of Laparoscopic Surgery (FLS), an educational program developed by the Society of American Gastrointestinal and Endoscopic Surgeons and endorsed by the American College of Surgeons. The FLS program is an education and assessment package consisting of an online cognitive module and a manual skills assessment. The skills component consists of the following 5 tasks: peg transfer; precision cutting; placement of a ligating loop; and suturing using extracorporeal and intracorporeal knot tying. The tasks are scored for efficiency and precision, and each task has a predetermined cutoff time. Google Inc. has introduced Glass, a wearable computer containing a heads-up display, a speaker, a camera, a battery and a flash drive mounted on a titanium eyeglass frame. The display allows users to pull up information as they would on any other computer with a simple voice command. It has a camera that offers a point-of-view image and the ability to take both photos and videos while the device is worn. Although there are reports of the potential utility of Glass for medical doctors in the printed and online press, very little has been published in the peer-reviewed medical literature. To our knowledge, Google Glass has not been used in the training or evaluation of FLS yet. Thus, the purpose of this study is to assess the feasibility of evaluating the FLS skills component using Google Glass. This study will use FLS scoring data and participant feedback to assess the administration of the FLS examination with remote proctoring. The student will be involved with data collection, management and analysis. The student will also have an opportunity to learn FLS skills and to test Google glass. Page 18 of 47 The risk factors associated with foot deformity in diabetic foot ulcer patients referred to wound care clinic at Women’s College Hospital Supervisor Name: Afsaneh Alavi Hospital/Research Institution: Women’s College Hospital Email: afsaneh.alavi@utoronto.ca Brief Project Description The relationship between foot deformity, and ulceration has been explored previously. For example, studies have shown that foot morphology affects peak plantar pressure1 and subsequent plantar pressure is related to ulceration.2–4 Another study found, retrospectively, that everted calcanei were associated with medial metatarsal head ulcers, while inverted calcanei were associated with lateral metatarsal head ulcers.5 Foot deformities such as hammer/claw toe deformity or hallux limitus have been significantly associated with ulcer incidence in a univariate analysis.6 Thus, previous research indicates that foot morphology (foot type) and foot deformity can affect foot ulcer occurrence and foot ulcer location directly by ulcer development5,6 or indirectly by increased plantar pressure.2–4 This study further explores the relationship between foot type or foot deformity and ulcer as prospective study. This study will further help us understand how foot shape is associated with the development of foot ulcers. No formal studies have been conducted to determine the prevalence of foot deformity as a risk factor in diabetic foot ulcer patients in the Canadian population. The aim of this study is to determine such prevalence in this population. We also aim to determine the risk factors and the comorbidity associated with diabetic foot ulcers including neuropathic versus neuroischemic foot ulcers. Objectives: The primary objective of this study is: • To determine the prevalence of foot deformity as risk factor in diabetic foot ulcer patients. Secondary objectives in this study include: • To determine the risk factors associated with diabetic foot ulcers. • To determine the characteristics of diabetic neuropathic versus diabetic neuroischemic foot ulcers. Page 19 of 47 A Study to Identify the Prevalence of, Risk Factors for, and Effect of Alternative Antimicrobial Administration in Patients who Carry Ciprofloxacin Resistant Enteric Organisms in a Population of Patients Undergoing Transrectal (TRUS) Biopsy of Prostate Supervisor Name: Frank Papanikolaou Hospital/Research Institution: Trillium Health Partners / The Credit Valley Hospital Email: frank.papanikolaou@trilliumhealthpartners.ca Brief Project Description Background Ciprofloxacin is an antibiotic drug of the fluoroquinolone (FQ) class. It has been shown to be effective against organisms causing urinary tract infections (UTIs) and as a result is often used in prophylactic treatment in procedures such as TRUS guided prostate biopsies. Recent studies have shown an increase in the number of infective complications after TRUS despite ciprofloxacin prophylaxis. Researchers have traced this rise in infections to an increase in the bacterial resistance of FQs including ciprofloxacin. This study will determine the prevalence of ciprofloxacin resistant enteric organisms in patients undergoing TRUS and to determine risk factors for carriage of the resistant bacteria. Matching the presence of the resistant bacteria with certain risk factors will help to predict which patients are likely to have the resistant bacteria. This will allow tailored antibiotic prophylaxis, thus reducing the patient’s chance of becoming infected. Based on our knowledge, there have not been any previous studies which have prospectively tried to view a wide array of potential risk factors for carriage of the resistant bacteria, in addition to finding the prevalence of the resistant bacteria in this population. Study Design and Methodology The urologist will perform a Digital Rectal Examination (DRE) and PSA blood test, and will determine if the patient needs a TRUS biopsy. The patients will be informed about the study and be given the consent form along with a brochure regarding the study. At the Urology Research Clinic appointment, the study nurse will obtain the consent form from the patient, and collect a rectal swab sample if the patient agrees to participate in the study. The patient will also fill out a questionnaire regarding risk factors which may be associated with Cipro resistant bacteria. All information contained in the questionnaire will be kept confidential, via a generated participant ID, and will only be viewed by the study team for research purposes only. The nurse will submit the swab sample to the CVH Microbiology laboratory, where it will be incubated using a selective medium in order to identify the presence of ciprofloxacin resistant enteric organisms. The results of the swab will be disclosed to the study team for research purposes and be recorded in the patient’s chart, so that the urologist may determine the appropriate treatment for the patient. If the patient is found to be carrying a ciprofloxacin resistant organism, their attending urologist will determine appropriate treatment prior to the biopsy. Patients without the ciprofloxacin resistant organisms will be given the standard prophylaxis of oral ciprofloxacin, whereas the patients with the ciprofloxacin resistant organisms will be given a more tailored prophylactic regimen. Both groups (patients with the resistant bacteria and patients without the resistant bacteria) will then undergo the TRUS guided biopsy under the standard protocol. Six weeks after the biopsy all patients will be contacted to determine if they suffered any complications post biopsy. Summary The study is underway at CVH and we are confident that it has the potential to change the standard of care and provide a process by which physicians can decrease the frequency of infective complications after prostate biopsies, preventing sepsis, urinary tract infections, and potential death. Page 20 of 47 The risk factors associated with chronic venous ulcers in Canadian Population Supervisor Name: Afsaneh Alavi Hospital/Research Institution: Women’s College Hospital Email: afsaneh.alavi@utoronto.ca Brief Project Description Venous ulcers are a common medical condition that affect up to 2% of the population in developed countries and may lead to devastating consequences. These ulcers typically take a long time to heal and can cause a deterioration in a patient's quality of life. It has been estimated that the complications of venous ulcers may cost taxpayers about 1% of a developed nation's annual healthcare budget. Previous studies have characterized the risk factors for the development of venous ulcers in different parts of the world. Different treatments have also been proposed for the management of this difficult condition, with varying degrees of success. The aim of this retrospective cohort is to examine the characteristics of a population of Canadian patients with venous ulcers and determine the risk factors associated with chronic venous leg ulcers. We also compare the population who received surgery in compare to patients who were managed non operatively in terms of duration of ulcers . The objective of this project is to determine the risk factors associated with the development of venous ulcers in our Canadian patient population and compare the outcomes between patients who have received a surgical intervention with those who were managed non-operatively. We hypothesize those patients who receive surgery for the management of venous ulcers have a better outcome than those who are managed non-operatively. A retrospective chart review will be carried out of the included patient population. The patient charts will be mined for the data points .After the completion of data collection, descriptive statistics will be generated using the statistical software package, SAS 9.3. The baseline patient characteristics will be calculated and a logistic regression model will be developed to identify the factors associated with adequate ulcer healing and assess whether surgery is a significant predictor of wound healing. Page 21 of 47 Are lower doses of cyproterone acetate effective in the hormonal treatment of transgender females Supervisor Name: Raymond Fung Hospital/Research Institution: Toronto East General Hospital Email: rfung@tegh.on.ca Brief Project Description Introduction Though up to 0.5% of the population identifies as transgendered,1 there are very limited data examining the dosing of hormone therapy regimens for transition from male to female. In the hormonal treatment of transgender females, an anti-androgen agent is used in combination with estrogen to block the effects of testosterone, enabling feminization to occur. Cyproterone acetate is one of two anti-androgen agents commonly used, the other being spironolactone. The recommended dose range of cyproterone acetate is 50-100mg daily, according to the Endocrine Society Practice guidelines published in 2009. 2 The European Network for the Investigation of Gender Incongruence have published short term data using a standardized protocol of estradiol 4mg in combination with cyproterone at a dose of 50mg per day.3 However, doses of cyproterone lower than 50 mg per day have not been studied in this population. Rationale It is well known that estrogen increases thrombotic risk.4–6 Whether cyproterone acetate confers additional thrombotic risk when used in combination with estrogen is unknown. However, looking at the oral hormonal contraceptive literature, the oral combined contraceptive containing ethinyl estradiol and cyproterone acetate has been associated with an increased risk of thrombosis compared with other second generation oral contraceptives with similar doses of ethinyl estradiol, suggesting that cyproterone may confer additional risk.4 Therefore, it is important to examine whether a lower dose of cyproterone acetate is effective in the treatment of transgender females, to minimize any possible increased thrombotic risk. Furthermore, other known risks of cyproterone, such as depression, hepatotoxicity, and fatigue may also be minimized by using a lower dose. Dose-dependent hepatotoxicity has been reported; fatal case reports of hepatic failure with doses >100mg per day. 7 Objectives: To determine whether a dose of less than 50 mg of cyproterone acetate daily is enough to suppress levels of testosterone into the physiologic female range in combination with standard recommended doses of estrogen in patients who are transitioning from male to female.

With an aging population and individuals living longer lives, healthcare costs continue to rise at rates faster than other parts of the economy. Exacerbating these challenges is the growing numbers of individuals with chronic disease and multi-morbidities, a proportion of who became complex patients. Arthritis, specifically osteoarthritis (OA), is one of the most common, disabling, and costly chronic diseases. Arthritis is the most frequent cause of chronic pain, which is debilitating to the individual and extremely costly to society. Primary care is most often the first contact for people seeking symptom relief. This CIHR-funded study will employ the approach of institutional ethnography (IE) to investigate how primary care physicians define, encounter and manage these complex patients. Our overarching research question will be “How do primary care physicians describe the work they do in caring for patients with complex chronic conditions?” This question will become the starting point, rather than the end point, to allow our team to explicate how care is put together at the level of the institution with attention to those at the local practice. Using an expanded definition of work will allow us to understand the many types of work that physicians do (e.g., making phone calls, filling out forms, email) and also alerts us to how the discourses and concerns of institutions enters into the everyday language of care providers. The CREMS summer student will have an opportunity to be involved in qualitative data collection and analysis for this project, working with a multi-disciplinary team.

There exists a significant body of literature on how women make the decision to breast What is more poorly understood is the decision making process among socially vulnerable women. Recent data from Ontario suggests this population is less likely to initiate and continue breastfeeding. Through brief semi-structured interviews, we will gather data on how women with substance use feed their babies and why they choose one method over the other. We hope to find out what information was given to these women about breastfeeding or other feeding choices and which of that information was helpful for decision-making. We will explore both personal and system factors that impact these choices using a woman centered lens. The collected data will later be used to design appropriate patient and provider education about breastfeeding, infant feeding and substance use. Page 24 of 47 How does ethnicity affect the effectiveness of Ulipristal Acetate for the treatment of uterine fibroids? Supervisor Name: Ally Murji Hospital/Research Institution: Mount Sinai Hospital Email: amurji@mtsinai.on.ca Brief Project Description Fibroids are a common benign condition that can be found in over 70% of women. About half of these women will be symptomatic from their fibroids. In June 2013, Health Canada approved a new selective progesterone receptor modulator, ulipristal acetate (UA), for the treatment of symptoms from uterine fibroids. Health Canada’s decision was made based on two phase III randomized controlled trials published in the New England Journal of Medicine. The patient population in these trials consisted mainly of European descent. Due to this significant limitation, other regulatory authorities such as the US FDA has not been so quick to approve this drug until more ethnicspecific data is available. This data will not be available for yet another few years. Objective: To determine how ethnicity affects the efficacy of UA in the treatment of uterine fibroids, with respect to improvement in quality of life and change in fibroid size. Methods: At Mount Sinai Hospital, we have started a prospective database of women who have been started on UA. We have followed these women to assess treatment response. This is the largest Canadian database of this kind. REB approval for this study has been obtained. Page 25 of 47 Using the F-scan to assess plantar pressure using the recumbent bike Supervisor Name: Robyn Evans Hospital/Research Institution: Women’s College Hospital Email: rmejones@rogers.com Brief Project Description Neuropathy is the most important risk factor for the development of a diabetic foot ulcer. Ulcers occur in about 25% of people with diabetes with most being on the plantar aspect of the foot on either the first or fifth metatarsal head. Once these ulcers heal there is always a risk to re-ulcerate due to the ongoing challenges related to neuropathy and pressure off-loading with foot-ware. Patients with diabetes are encouraged to exercise in an effort to manage healthy weight and improve cardiovascular function. There is no recommendation for what is a reasonable exercise that would allow for reduced plantar pressure to the foot in these high-risk patients. The study is being undertaken to determine what the plantar pressure is while using the recumbent bike. The F-scan is able to measure and record the pressure areas on the foot. This study would evaluate the pressure areas on the plantar aspect of the foot in healthy subjects with no neuropathy, then to extend this to patients with neuropathy if the results are encouraging. These results will be compared to the pressure obtained on the plantar foot while walking which is the usual prescribed exercise. Page 26 of 47 Barriers to the Optimum Management of Diabetic Foot Ulcers Supervisor Name: Carol Ott / Robyn Evans Hospital/Research Institution: Women’s College Hospital Email: rmejones@rogers.com Brief Project Description Optimum management of diabetic foot ulcers requires timely treatment at a multidisciplinary clinic. As a referral center it is apparent that there are barriers to the delivery of optimum care to this high-risk population. Some of the factors that will be assessed are; time to referral to a specialty clinic, availability of appropriate off-loading devices and work accommodation to allow for modified activities. The purpose of this study is to retrospectively review charts of patients with diabetes to assess what the barriers to treatment are and how this can impact overall healing rates and complications. A survey will also be developed to understand the patient perspective with regarding barriers to care. This study will highlight the factors that are missing in the care of the diabetic patient with a foot ulcer and what can be done to improve on the care of this high risk population. Page 27 of 47 Improving patient reported nausea and vomiting in cancer patients undergoing moderately and highly emetogenic chemotherapy at Trillium Health Partners – A quality improvement initiative Supervisor Name: Katherine Enright Hospital/Research Institution: Trillium Health Partners / Credit Valley Hospital Email: katherine.enright@trilliumhealthpartners.ca Brief Project Description Background Chemotherapy induced nausea and vomiting (CINV) remains one of the most feared treatment related toxicities for patients undergoing systemic therapy for cancer. CINV has been shown to both have a negative impact on patient experience and quality of life, as well as increase the likelihood of dose delays, dose reductions and unplanned hospital visits. Advances in anti-emetic prophylaxis over the past decade have resulted in significant improvements in CINV control, but despite this up to 70% of patients receiving moderately or highly emetogenic chemotherapy still report some nausea and vomiting. In 2013 Cancer Care Ontario released updated anti-emetic guidelines which included (among other recommendations), the incorporation of a new class of anti-emetics (NK-1 antagonists) in most patients receiving moderate-highly emetogenic therapy. Due to funding restrictions, these guidelines could not be implemented universally at time of initial publication. As of September 2014 funding of these new anti-emetic agents is now available for most cancer patients, and can be universally be implemented. As we work towards implementing the new anti-emetic guidelines at Trillium Health Partners we are undertaking a quality improvement initiative to ensure that our treatment is meeting guideline recommendations and that this change is resulting in improved patient outcomes. Through this work we aim decrease the percentage of patients who report grade 2 or higher nausea or vomiting with cycle number 1 of their moderately-highly emetogenic chemotherapy to <10%. Methods Our primary outcome measure of interest will be percentage of patients undergoing moderate-highly emetogenic chemotherapy that report grade 2 or higher nausea or vomiting with their first cycle of chemotherapy. We will also look at numerous process measures such as the percentage of patients who are prescribed NK1 antagonists, the percentage of patients who received guideline recommended care, patient reported compliance with prescribed anti-emetics. We will also examine the impact on unplanned hospital visits. The updated anti-emetic guidelines will be implemented in a stepwise fashion (provider education, integration into the computerized order entry system, surveillance and reporting). Using rapid cycle improvement methodology we will evaluate the impact of each stage and use this to inform the next step of implementation. Students will be exposed to data collection and analysis using standard statistics and statistical process control charts. They will collect quantitative date (percentage of patients who develop CINV) and qualitative data (patient experience). They will also be involved in the quality improvement process and gain exposure to Plan-Do-Study-Act cycles and other quality improvement tools such as Ishikawa diagrams, pareto charts and process maps. Page 28 of 47 Improving hepatitis B screening rates in patients undergoing adjuvant or curative intent cytotoxic chemotherapy at Trillium Health Partners – A quality improvement initiative Supervisor Name: Katherine Enright Hospital/Research Institution: Trillium Health Partners / Credit Valley Hospital Email: katherine.enright@trilliumhealthpartners.ca Brief Project Description Background Chemotherapy induced hepatitis B viral reactivation is a serious and potentially preventable complication of cytotoxic chemotherapy treatments. The clinical outcomes of hepatitis B reactivation can range from asymptomatic elevations in liver enzymes to hepatic failure and even death. chemotherapy regimen in question. The risk of reactivation is dependent on both patient characteristics and the Reactivation has been reported in up to 67% of patients with non-Hodgin’s lymphoma treated with rituximab containing regimens, and 21% of breast cancer patients undergoing standard adjuvant treatment. In patients with evidence of latent hepatitis B infection, prophylactic treatment with the antiviral lamivudine has been shown to decrease the likelihood of biochemical reactivation. Cancer Care Ontario has recently released updated screening recommendations that recommends at least hepatitis surface antigen testing prior to initiating cytotoxic chemotherapy in patients being treated with adjuvant or curative intent. As we work towards implementing the new screening recommendations at Trillium Health Partners we are undertaking a quality improvement initiative to ensure that our treatment is meeting guideline recommendations and that this change is resulting in improved patient outcomes. Through this work we aim increase the number of patients who have been screened for a latent hepatitis B infection prior to starting on adjuvant or curative intent cytotoxic chemotherapy for either solid tumours or lymphoma to 90%. Methods Our primary outcome measure of interest will be percentage of patients undergoing adjuvant or curative intent cytotoxic chemotherapy that have a screening test in the medical record prior to the start date of chemotherapy. We will also look at additional measures including percentage of patients with elevated liver enzymes and percentage of hepatitis reactivations. Balance measures such as increase use of lamivudine, increase cost of screening and delays in treatment will also be tracked. Clinical, patient and provider factors associated with screening will be evaluated to help target quality improvement interventions. The first process improvement step (incorporation in pre-printed chemotherapy orders), will be initiated in March 2015. The student will evaluate the impact of this plan-do-study-act cycle on screening rates. Based on the results of the first process improvement phase, the student will be involved in developing and implementing further rapid cycle improvement cycles. Students will be exposed to data collection and analysis using standard statistics and statistical process control charts. They will collect quantitative date (percentage of patients who are screened) and qualitative data (patient experience). They will also involved in the quality improvement process and gain exposure to Plan-Do-Study-Act cycles and other quality improvement tools such as Ishikawa diagrams, pareto charts and process maps. Page 29 of 47 Pills or post-coital IUD? Factors associated with women’s choice of emergency contraception Supervisor Name: Sheila Dunn Hospital/Research Institution: Women’s College Hospital Email: sheila.dunn@wchospital.ca Brief Project Description Emergency contraception reduces the risk of pregnancy after unprotected intercourse and is used by almost 4% of women aged 20-24 each year. commonly used method. Emergency contraceptive pills (ECP) are by far the most However, insertion of a copper intrauterine device (IUD) is much more effective and provides reliable long term contraception. We are conducting a study in a sexual health clinic to examine women’s knowledge and choice of emergency contraception (either ECP or IUD), satisfaction with that choice and use of effective contraception 3 months after presentation. The CREMS student project will help complete our study that is recruiting and following women who present for emergency contraception at the Bay Center for Birth Control. The study determines women’s knowledge of the methods, their choice of emergency contraception and their satisfaction and use of effective contraception 3 months after their presentation. The student will assist in the final completion of that project and will undertake a sub-study, done through chart review, of all women presenting for emergency contraception from July 2014-July 2015 to examine EC choice and associated demographic and reproductive health variables. The CREMS student will assist the research team with the following: 1. 3 month follow-up telephone surveys with women recruited into the follow-up study 2. chart reviews, data abstraction and input 3. assist with analysis and interpretation 4. assist with administrative requirements of the study The student will provided office space and a computer at the Bay Centre for Birth Control and will be directly supervised by Dr. Sheila Dunn, a family physician researcher and Scientist at the Women’s College Research Institute (WCRI). There are opportunities to gain experience a clinical environment that delivers reproductive health care and to participate in the WCRI Summer Research Student rounds and seminars. Page 30 of 47 Implementation and Evaluation of a Program for “Rapid Assessment of Febrile Travelers” (RAFT) in Primary Care and Emergency Room Settings in Ontario Supervisor Name: Andrea Boggild Hospital/Research Institution: UHN / Toronto General Hospital Email: andrea.boggild@utoronto.ca Brief Project Description Fever in the returned traveler is a common presentation to the emergency room (ER) and primary care, and may herald serious and life-threatening illness, the most important of which is malaria. Thus, fever after travel warrants prompt attention and is considered a medical emergency. Yet each year, several Canadians die of malaria due to delay in diagnosis and/or treatment, and many more become critically unwell. In most ERs, if a returned traveler with fever does not need hospital admission, there is no mechanism in place for rapid follow-up assessment, and the patient will simply wait for the next available outpatient infectious diseases appointment. Meanwhile, primary care offices routinely send travelers with fever to the ER due to a lack of rapid, safe alternatives. We plan to scale-up a simple health-system innovation that reduces barriers to safe and rapid care of ill returned travelers. Our "Rapid Assessment of Febrile Travelers" (RAFT) clinic at UHN/Mount Sinai has improved delivery and efficiency of care, and reduced emergency room bed usage at UHN/Mount Sinai. We plan to expand the RAFT program to community ERs and primary care clinics in order to optimize the delivery of care to ill returned travelers in Ontario. The CREMS student will work closely with our local RAFT team in the Tropical Disease Unit of TGH as well as our RAFT collaborators at other downtown centres. Keywords: Fever; malaria; patient-centered care; travel medicine; tropical medicine. Page 31 of 47 High Volume Foleys increasing Vaginal Birth Feasibility Trial Supervisor Name: Anne Berndl Hospital/Research Institution: Sunnybrook Health Sciences Centre, SRI Email: anne.brerndl@sunnybrook.ca Brief Project Description The rising rate of caesarean sections is concerning to both women and physicians. One quarter of Ontario women in their first pregnancy undergo an induction of labour, and one third of these women deliver by caesarean section. Before inducing labour, a woman’s cervix often requires “ripening”, a process that makes it open and soft. Most Canadian obstetricians use prostaglandins for cervical ripening, and a minority use Foley catheters filled to 30-60cc. Currently no method of cervical ripening has been found superior regarding risk of caesarean section. However, a recent meta-analysis suggests Foley catheters filled to 80cc may be associated with a greater chance of vaginal birth. This proposed study aims to determine if it is feasible to successful insert a Foley catheter for cervical ripening and inflate it to 80cc, and to assess the acceptability of this procedure to Ontario women and maternity care providers. This information will inform the design of a larger clinical trial comparing cervical ripening with 80cc Foley catheters to prostaglandins with rate of caesarean birth as the outcome. This is a first step towards clinical practice changes that could have a significant impact on the caesarean section rate and the wellbeing of women and babies. Page 32 of 47 Clinical Research in Adolescent Bipolar Disorder Supervisor Name: Benjamin Goldstein Hospital/Research Institution: Sunnybrook Health Sciences Centre, SRI Email: benjamin.goldstein@sunnybrook.ca Brief Project Description The focus of this CREMS project is on adolescent bipolar disorder. The selected student will be integrated into the overall activities of the laboratory, which includes pharmacology graduate students, undergraduate research students, and research staff. The student will gain exposure to current methods being applied in the laboratory, including neuroimaging (MRI), vascular imaging (ultrasound, peripheral arterial tonometry), computerized cognitive testing, serum biomarkers, genetics, and novel complementary therapeutics. Descriptions of current ongoing studies can be found at the following website: http://sunnybrook.ca/content/?page=bsp-youth-bipolar-disorder-research The selected student will have access to two archival datasets, one based on approximately 116 adolescents enrolled in a research registry at Sunnybrook, the other based on approximately 400 adolescents and young adults participating in a multi-site cohort study in the United States. Working together with the supervisor, the selected student will identify a specific project based on one of the above datasets. The student will be expected to undertake the necessary literature review and to generate one manuscript for submission to a peer-reviewed journal. Guidance will be provided by the supervisor and other laboratory members regarding literature search and statistical methods. Page 33 of 47 Do pediatric clavicle fractures need to be managed by orthopaedic surgeons? Supervisor Name: Mark Camp Hospital/Research Institution: SickKids Email: mark.camp@sickkids.ca Brief Project Description Clavicle fractures are one of the most common fractures sustained during childhood. In Ontario, children with clavicle fractures are managed by orthopaedic surgeons who follow them until the fracture has healed. However, the rate of requiring surgical intervention either at the time of injury or after healing occurs is anecdotally extremely low which begs the question: do pediatric clavicle fractures need to be managed by orthopaedic surgeons or can they be managed more cost-effectively by pediatricians and family doctors? This project will include a retrospective chart review to determine the rate of surgical intervention in pediatric clavicle fractures at the Hospital for Sick Children from 2005 to 2014. The results of this audit will provide the evidence for a clinical practice pathway for pediatric clavicle fractures in Ontario. This clinical practice pathway will be publically available on the SickKids website (created as part of a separate research project). This project can be realistically completed within the CREMS Summer Research Program. Funding is available to present this work at either the COA meeting in Halifax in 2016 or the CAEP meeting in Quebec City in 2016. Presentation at other meetings will also be considered. Page 34 of 47 Eliminating Digestive Irregularities caused By Late Effects (EDIBLE) of abdominopelvic radiation: A Pilot Study of a culinary and nutrition intervention Supervisor Name: Jennifer Jones / Sarah Ferguson Hospital/Research Institution: Princess Margaret Cancer Centre Email: jennifer.jones@uhn.ca / sarah.ferguson@uhn.ca Brief Project Description Background: Patients diagnosed with gynecological (GYN) cancers are commonly treated with radiation therapy to the pelvic area. Exposing the pelvic area to radiation therapy can result in long-term gastrointestinal (GI) side effects. Providing self-management support to GYN patients who suffer from GI symptoms after radiation therapy may be an effective strategy to help them improve their QoL. The dietary management of GI symptoms resulting from radiation therapy includes increasing soluble fibre and limiting insoluble fibre, fat and lactose. We are proposing to conduct a pilot study to evaluate a newly developed nutrition and culinary education intervention for GYN cancer patients (EDIBLE). The research objectives are to: 1) assess the feasibility and acceptability of the methods and the intervention; and 2) a preliminary estimate on the efficacy of the intervention on bowel symptoms (primary clinical outcome); QoL, knowledge and food intake (secondary outcomes). The summer CREMS student will assist with the pilot of EDIBLE and work closely with Drs. Jones and Ferguson and the research and clinical team at ELLICSR (http://ellicsr.ca/) and will also take part in the ELLICSR Summer Student Program which includes a series of seminars and presentations to introduce students to cancer survivorship and research. Page 35 of 47 Incidence of Intracranial Hemorrhage in Pediatric Oncology Patients Supervisor Name: Lani Lieberman Hospital/Research Institution: Toronto General Email: lani.lieberman@uhn.ca Brief Project Description Introduction Intracranial hemorrhage (ICH) is a rare, serious bleeding complication seen in thrombocytopenic oncology patients. It is unclear why some patients with severe thrombocytopenia develop ICH and others do not. Objectives 1. To identify the characteristics, incidence, and risk factors for ICH development in pediatric oncology patients. 2. To assess major morbidity and mortality 30 days following the event. Methods This retrospective case control study (nested within a cohort) will be performed at the Hospital for Sick Children. been identified through the Pediatric Oncology Group of Ontario Networked Information System (POGONIS). Cases have Oncology patients ≤ 19 years old, treated between 1995-2013 and diagnosed with an ICH will be eligible. Controls will be similar to cases, except for ICH, and a maximum of 5 will be selected randomly from the same institution and the same diagnosis year. The original charts will be reviewed to augment information contained within POGONIS. Variables of interest include patient demographics, laboratory results, radiological reports and patient outcome data. ICH will be based on radiographic diagnosis. Analysis The incidence of ICH and the types of patients affected will be determined utilizing the entire population of pediatric oncology patients. Characteristics of the different bleeds will be presented (clinically or radiologically overt). To assess risk factors, a multivariable logistic regression model will be constructed where the outcome is case or control status and the variables of interest will be examined. Odds ratios and confidence intervals will be determined. Conclusion Results of this study will provide an estimate of the incidence of ICH in pediatric oncology patients and attempt to link this event to risk factors including hematologic lab values. This foundational information is required to generate hypotheses to be tested in larger, international collaborative studies. Currently, transfusion thresholds drive ordering practice to prevent ICH. Future studies will investigate the value of using other risk factors or a bleeding scale prior to ordering a platelet transfusion. Page 36 of 47 Thoracic CT using Low Dose Dual Energy Temporal Subtraction : A Feasibility Study in Patients with Chronic Thromboembolic Pulmonary Hypertension Supervisor Name: Narinder Paul Hospital/Research Institution: University Health Network Email: narinder.paul@uhn.ca Brief Project Description Acute pulmonary embolism (PE) is a life threatening condition in which a blood clot lodges in the pulmonary arteries (PA). 1% of acute PE becomes chronic PE resulting in pulmonary artery hypertension (PAH) and eventually Chronic Thromboembolic Pulmonary Hypertension (CTEPH). CTEPH is a significant cause of death for Canadian patients due to right heart failure. Surgical clot removal, pulmonary thromboendarterectomy (PTA) is the only cure but has a perioperative mortality of ~5%. The key to reduce perioperative mortality and to improve functional status is to stratify patients at higher risk by accurately measuring the severity of PAH and pulmonary vascular resistance (PVR) pre and post PTA. Therefore, CTEPH patients undergo multiple investigations including: 2d echocardiography, to assess right heart pressure and function; CT pulmonary angiography (CTPA) to document severity and distribution of PA clot; VQ scans, to confirm severity and pattern of lung perfusion deficits; invasive cardiac/pulmonary catheterization, to establish right heart and pulmonary pressures; and exercise tests to establish functional status. Our team has developed a technique called low dose temporal subtraction (LD-TS) by performing low dose computed tomography (LDCT) at the time of CTPA. The LDCT demonstrates areas of lung heterogeneity; these correspond to the severity of PVR. The LD-TS demonstrates pulmonary blood distribution; this information can be compared to the data from the V/Q scan and from pulmonary artery catheterization. The purpose of this study is to test the utility of LD-TS in an established cohort of CTEPH patients in order to evaluate whether LD-TS provides information that is useful in patient management. In particular, we will determine whether LD-TS could replace other tests that are currently performed in CTEPH patients. If successful, LD-TS would provide a cost effective, non-invasive, comprehensive and time efficient evaluation of CTEPH patients pre and post PTA. Page 37 of 47 Correlation of cortical perfusion and cognitive dysfunction between Multiple Sclerosis subtypes using a novel quantitative perfusion sequence Supervisor Name: Richard Aviv Hospital/Research Institution: Sunnybrook Email: richardaviv@sunnybrook.ca Brief Project Description Exciting research opportunity with opportunity to lead author a manuscript if appropriately skilled. The project utilizes novel imaging and plasma biomarkers to explore the link between cortical quantitative blood volume (CqCBV) reduction, cortical lesion load, perivascular inflammation and cognitive impairment. Prior CqCBV localization to anatomically appropriate regions, high correlation with individual cognitive domains and improved prediction of cognitive impairment over established indicators support the validity of the technique as a biomarker of cortical pathology and disease progression. Our prospective data should add to this body of data. The anticipated basic role is to facilitate data processing and analysis in a prospective study of cognitive impairment and Multiple Sclerosis using novel MRI perfusion imaging. Ideally candidate will have a computational sciences or engineering background. Work will be supported by an experienced research team with multidisciplinary expertise in Radiology, engineering and computational sciences. MATLAB ability is expected. Page 38 of 47 Is neurovascular coupling impaired in patients with concussion? Supervisor Name: David Mikulis Hospital/Research Institution: Toronto Western Hospital Email: mikulis@mac.com Brief Project Description Recent work in patients with concussion has indicated that significant blood flow abnormalities can occur during the recovery phase of this condition. Previous studies examining resting blood flow usually indicate that it is decreased. However it is unclear if the decrease is appropriate for the level of brain activity that may similarly be decreased. It would be important to know if the usual coupling of blood flow to neural activity is impaired in these patients since it is theorized that neurovascular uncoupling may be related to symptoms. We have developed a method for assessing the mechanism that controls brain blood flow using a device that provides precision control over arterial levels of CO2, a potent vasodilator. A unique advantage of this device is that it can raise arterial levels of CO2 by 10 mmHg within 2 breaths. This then provides the ability to measure the dynamic response of the blood flow control mechanism to a vasodilatory stimulus. Transfer function analysis can then be applied to determine the transient response and magnitude of this response. These can then be compared to our database of age matched controls for testing of the relationship between NVU if present and symptoms. Page 39 of 47 The Relationship between health literacy and knowledge of prenatal screening options for trisomy 21: a needs assessment Supervisor Name: Amanda Selk Hospital/Research Institution: Mount Sinai Hospital Email: aselk@mtsinai.on.ca Brief Project Description This study aims to assess knowledge among pregnant women undergoing prenatal screening for Trisomy 21(prenatal screening) at Mount Sinai Hospital. The study will also examine the relationship between knowledge of screening options and health literacy among participants. There are multiple testing options for prenatal screening and explaining them to patients can be time consuming and difficult. Prenatal screening is considered an optional test. After a positive test patients can undergo confirmatory testing (chorionic villous sampling, amniocentesis) and choose to either continue or terminate the pregnancy if the positive screening result is confirmed. Mount Sinai Hospital has recently developed a structured counseling session open to all their pregnant patients to aid in the complexities of counselling. It is unknown whether the patients are benefiting from this counseling session or are even aware of its existence. Of the patients who are not utilizing this counseling option, the quantity and quality of any counseling they are receiving is unknown. Previously published literature suggests that there is a large knowledge gap among pregnant women on crucial information pertaining to prenatal screening. Knowledge regarding screening in Canada has not been assessed in studies for >20 years and the screening options have changed dramatically in that period of time. This study is a cross-sectional study that utilizes a demographics questionnaire as well as previously validated measures of knowledge regarding prenatal screening and health literacy. REB has already been attained for this study. This study started as a DOCH-2 project in 2014 and some patients have already been recruited. The job of the CREMS student would be to finish recruiting, data analysis and writing up the results for publication in an obstetrical journal.

Little information is present at These injuries may involve the quadriceps, patella, patellar tendon, medial patellar retinaculum or medial patellofemoral ligament. STUDY HYPOTHESIS The purpose of this study is to determine the prevalence of extensor mechanism injuries in the setting of multi-ligament knee injuries. STUDY DESIGN This is a retrospective study. Dr. Daniel Whelan’s patients who have a multi-ligamentous knee injury or knee dislocation and whom have had a Knee MRI will be recruited for this retrospective study. For patients who have multiple MRI’s, the MRI that is performed soonest after the injury will be used. sheet will be used to collect data on all of those patients. A data The MRI images will be evaluated by Dr. Pearce and Dr.Whelan. The images will be evaluated independently, and disagreements resolved by consensus. The summer student will transcribe and organize our data sheets and sit with us during read outs. Page 41 of 47 Novel Noninvasive Assessment of Kidney Transplant Fibrosis with Magnetic Resonance Elastography Supervisor Name: Anish Kirpalani Hospital/Research Institution: St. Michael’s Hospital Email: kirpalania@smh.ca Brief Project Description OBJECTIVE: The primary objective of this study is to measure organ stiffness through a non-invasive test called Magnetic resonance elastography (MRE). INTRODUCTION: Kidney transplantation has greatly improved the quality of life and survival of people living with kidney failure. Unfortunately, up to 60% of these people go on to have failure of their transplant within 10 years, in many cases requiring drugs and/or return to dialysis. The cause for transplant failure is almost always, at least in part, due to scarring of the transplanted kidney. There is currently no good test to detect this scarring. The best test we have is a needle biopsy, which is associated not only with significant bleeding risks, but also an inability to take sample and analyze the entire kidney. A new type of MRI called “MR elastography” has been proven to accurately measure scarring in the liver, but not yet in the kidney. It does not need any injections, can be done in 30 minutes, and may be able to measure scar throughout the entire kidney without needles. Our project aims to compare this new MRI test with needle biopsy. We will determine if it can measure scar in the transplanted kidneys of people with both normal and abnormal transplant function. This could drastically change how a doctor treats transplant failure. STUDY DESIGN: The study design is entirely prospective where patients with a history of renal transplantation (more than 1 year) will be eligible for this study. 25 patients with chronic renal allograft dysfunction and 25 control patients with normal renal allograft function will be selected. PREDICTED OUTCOMES: 1) MRE-derived stiffness measurements will be higher in scarred, dysfunctional kidneys and lower in healthy, normal functioning kidneys. 2) MRE-derived stiffness values will correlate positively with biopsy-measured fibrosis scores, and inversely with renal function. 3) Since fibrosis often pre-dates renal dysfunction, MRE-derived stiffness values will increase prior to increases in conventional biomarkers of renal function.

This is a weak recommendation based on very low-quality evidence. However, in practice, we have noted that lumbar punctures are often performed at lower platelet counts without platelet transfusion. The objective of this project is to determine 1) the frequency with which lumbar punctures are performed with a platelet count less than 50 x 109/L without platelet transfusion; 2) whether any bleeding complications occur as a result; and 3) whether bleeding complications are increased compared to lumbar punctures performed either with a platelet count of 50 x 109/L and above or after a prophylactic platelet transfusion. The study design will be a retrospective audit of all lumbar punctures occurring on the inpatient hemato-oncology ward and in the outpatient Odette Cancer Centre. The results of this audit may help to inform whether changes to the AABB guidelines are warranted. The medical student will be working with a hematology resident and transfusion medicine specialists on this project. By participating in this project, the medical student will have the opportunity to present the results at hematology rounds, submit an abstract to a national or international conference and have authorship in a publication. Page 45 of 47 Platelet transfusion threshold prior to lumbar puncture Name: Yulia Lin Hospital/Research Institution: Sunnybrook Health Sciences Centre Email: yulia.lin@sunnybrook.ca Brief Project Description The most recent 2014 AABB guidelines suggest that a prophylactic platelet transfusion should be administered for patients having elective diagnostic lumbar puncture with a platelet count less than 50 x 109/L. This is a weak recommendation based on very low-quality evidence. However, in practice, we have noted that lumbar punctures are often performed at lower platelet counts without platelet transfusion. The objective of this project is to determine 1) the frequency with which lumbar punctures are performed with a platelet count less than 50 x 109/L without platelet transfusion; 2) whether any bleeding complications occur as a result; and 3) whether bleeding complications are increased compared to lumbar punctures performed either with a platelet count of 50 x 109/L and above or after a prophylactic platelet transfusion. The study design will be a retrospective audit of all lumbar punctures occurring on the inpatient hemato-oncology ward and in the outpatient Odette Cancer Centre. The results of this audit may help to inform whether changes to the AABB guidelines are warranted.
