Filter by:This is a multi-site, multi-group study that obtained two sets of ultrasound scans from all enrolled participants. Participants underwent limited ultrasound scanning by both cardiac sonographers and abdominal sonographers. Algorithm's performance on the view identification task and the object labeling task is computed.
The investigators will conducted a hospital-based cohort study in our 15-year experience with DA aimed at investigating the long-term outcomes of the patients with DA, along with analyzing the impact of the tumor characteristics, operations and adjuvant therapy on survival outcomes.
Background In practice, however, not all anaemic patients undergo appropriate diagnostic tests for the detection of iron deficiency anemia (IDA), and a significant portion of patients with IDA do not receive endoscopic evaluations. Accordingly, this study aimed to detect the prevalence of significant endoscopic (upper and lower endoscopy) and pathological findings in patients presenting with unexplained iron deficiency anaemia. Methods One hundred twenty-four patients with confirmed IDA with no obvious cause who visited the Internal Medicine Clinic were randomly selected. Patients with active bleeding, pregnant or lactating females, or those with contraindications to sedation were excluded. Upper and lower endoscopy were held in the endoscopy unit of Specialized Medical Hospital and tissue biopsy from significant endoscopic findings was sent for histopathological examination.
The goal of this cohort study is to identify the lowest dose of Indocyanine Green (ICG) that achieves satisfactory intra-operative fluorescence for the assessment of gastrointestinal or genitourinary tract perfusion in children.
90% of colonoscopies are performed with general anesthesia (GA). GA carries risks and requires a prior anesthesia consultation, a dedicated team and technical platform on the day of the examination. These constraints increase the time it takes to organize examinations. This was particularly highlighted during the recent health crisis. The success of colonoscopy without GA varies depending on the patient's experience of the examination. Any measure allowing better tolerance of the exam is therefore likely to increase its success rate and avoid rescheduling the exam under GA. A 2017 meta-analysis showed that the use of virtual reality (VR) reduced pain and anxiety during care for burn victims, in trauma and oncology. In upper digestive endoscopy, retrospective studies have shown good tolerability of the examinations and a reduction in pain compared to patients with only local anesthesia. Thus, if the VR mask improves the success rate of total colonoscopy by improving tolerance and acceptability, more examinations without GA could be considered. It could also have an economic impact.
Swimming and other water activities at public beaches are increasingly popular leisure activities among Canadians. However, these activities can lead to increased risks of acquiring acute gastrointestinal illness and respiratory, skin, ear, and eye infections among beachgoers. These illnesses have a significant health and economic burden on society, with young children having much higher rates of illness than other age groups. Currently, baseline data are lacking on the risk of recreational water illness in Canada, and beachgoers may lack awareness and understanding of these risks and how to prevent them. This study will identify the burden of recreational water illness among Canadian beachgoers. The results will be used to develop recommendations for improving recreational water quality guidelines for safe swimming in Canada, as well as public health risk management and communication strategies with beachgoers. The study will use a mixed-methods approach, consisting of a prospective cohort study and a qualitative study of beachgoers. The investigators will determine the risk of acquiring recreational water illness outcomes in beachgoers that engage in different levels of water and sand contact. The investigators will examine differences in illness risks by beachgoer gender, age, and location. The investigators will examine relationships between fecal indicator bacteria (E. coli), environmental conditions, and host-specific biomarkers with the risk of gastrointestinal illness among beachgoers. The investigators will also evaluate beachgoer risk perceptions and behaviours toward recreational water quality. The study will take place at five targeted beach sites in British Columbia, Manitoba, and Ontario. The study will be coordinated by a multidisciplinary research team, with activities guided by a stakeholder steering group consisting of key knowledge users. The long-term goal is to reduce the burden of recreational water illness in Canada, contributing to improved public health.
The aim of this study was to assess common gastrointestinal symptoms in healthy Brazilian infants receiving goat milk-based infant formula (GMF) compared to cow's milk-based infant formula (CMF) during a 24 week intervention.
This study aims to validate the Alimetry® Gut-Brain Wellbeing Survey- Youth Version (AGBW-Y), a mental health scale developed for patients aged 12-17 years with chronic stomach symptoms.
A randomized, open-label, multiple-dose crossover phase 1 clinical trial to compare and evaluate the safety, pharmacokinetics and pharmacodynamics characteristics after oral administration of UI059 and UIC202201 in healthy adult volunteers
The ESPRESSO study is a collection of data from all computerised gastrointestinal histopathology reports in Sweden. This allows us to study risk factors for gastrointestinal disease, as well as the prognosis of gastrointestinal disease.
