Filter by: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 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. A review of the study has been published here: https://pubmed.ncbi.nlm.nih.gov/30679926/
Abdominal bloating and distension (ABD) are the most commonly gastrointestinal symptoms reported by patients with various functional gut disorders such as functional dyspepsia, irritable bowel syndrome and it is frequently associated with constipation. The pathophysiology of ABD is complex, often multifactorial and poorly understood. The reseach was hypothesised that short-term self-manual approaches and exercise for core muscles would have a positive effect on the symptoms of ABD.
Background: Accurate labeling of obstruction site on upright abdominal radiograph is a challenging task. The lack of ground truth leads to poor performance on supervised learning models. To address this issue, self-supervised learning (SSL) is proposed to classify normal, small bowel obstruction (SBO), and large bowel obstruction (LBO) radiographs using a few confirmed samples. Methods: A few number of confirmed and a large number of unlabeled radiographs were categorized based on the ground truth. The SSL model was firstly trained on the unlabeled radiographs, and then fine-tuned on the confirmed radiographs. ResNet50 and VGG16 were used for the embedded base encoders, whose weights and parameters were adjusted during training process. Furthermore, it was tested on an independent dataset, compared with supervised learning models and human interpreters. Finally, the t-SNE and Grad-CAM were used to visualize the model's interpretation.
In a prospective observational cohort study (n = 100), the investigators aim to assess the correlation between cardiac biomarkers, advanced echocardiography and cystic fibrosis genotype and severity and determine whether these are prognostic markers of heart disease in patients suffering from cystic fibrosis (CF).
Chronic physical conditions are defined as conditions that require ongoing management and treatment over extended periods of time. Chronic physical conditions are not only leading causes of death and disability in North America but they are commonly associated with mental distress and reduced quality of life. Online mind-body wellness programming ranging from physical activity to mindfulness interventions has been shown to be effective in improving mental wellness in a variety of chronic disease populations, but there is a need to evaluate scalable ways to deliver these programs. Building upon a previously developed online wellness program for inflammatory bowel disease (IBD) and primary biliary cholangitis (PBC), the research team has developed a mind-body wellness program for adults ≥18 years of age living with different chronic conditions (e.g., cirrhosis, PBC, heart failure). The 12-week program will be delivered online, and include follow- along mindful movement, breathwork and meditation routines, and a psychology based coping skills program. In a three-armed randomized controlled trial, the study will assess the impact on the primary outcome of anxiety and depression as measured through the hospital anxiety and depression scale (HADS). At the beginning and the end of the 12-week research study, participants will complete surveys to assess secondary/exploratory outcome measures including quality of life, fatigue, frailty, demoralization, and healthcare usage. After the program, the research team will conduct interviews with participants to allow them to share their other feedback about the program. The researchers will also send surveys to the participants eight weeks after the program ends to assess longer- term impacts on primary and secondary outcomes.
Bleeding from the gastrointestinal tract can originate from the small bowel. Typically, upper and lower endoscopies are unable to identify the site of bleeding and patients need to undergo special endoscopies with longer cameras to examine the small bowel and find the bleeding site. One of the most commonly used scopes to investigate the first part of the small intestinal is called "push enteroscopy". This is an upper endoscopy that uses a pediatric colonoscope, which is longer. To date, it is unknown what percentage of small bowel can be observed with this technique. Hence, this study aimed to determine the extent of small bowel examined by push enteroscopy. Consecutive patients with suspected bleeding from the small intestine will undergo a push enteroscopy and the depth of the examination will be marked with metallic clips. Subsequently, patients will have a capsule endoscopy, which is a little camera that will take multiple pictures of the whole small intestine. The percentage of small bowel that the push enteroscopy examined will be determined by the percentage of small bowel corresponding to the location of the clips visualized on capsule endoscopy.
Our study presents a detection model predicting a diagnosis of jaundice (clinical jaundice and occult jaundice) trained on prospective cohort data from slit-lamp photos and smartphone photos, demonstrating the model's validity and assisting clinical workers in identifying patient underlying hepatobiliary diseases.
The goal of this randomised controlled trial is to study the (cost-)effectiveness of home-based hypnotherapy by self-exercises in children with functional abdominal pain (FAP) or irritable bowel syndrome (IBS) in primary care. The main questions it aims to answer are: - What is the effect of home-based hypnotherapy by self-exercises on adequate relief of abdominal pain and discomfort in addition to care as usual of general practitioners (GPs), compared to care as usual of GPs alone in children with FAP or IBS? - What is the effect of home-based hypnotherapy by self-exercises in addition to care as usual by GPs compared to care as usual of GPs alone in children with FAP or IBS on: - Frequency and intensity of abdominal pain and discomfort - Pain severity - Daily functioning and impact - Anxiety and depression - Pain beliefs - Sleep disturbances - School absence - Use of health care services, including GP visits and referrals to secondary care - Costs (healthcare and societal perspective) Participants in the intervention group will receive home-based hypnotherapy 5 times a week for approximately 15-20 minutes a day during 3 months in addition to care as usual by their GP according to the Dutch society of GPs' guideline for children with abdominal pain. Participants in the control group will receive care as usual by their GP according to the Dutch society of GPs' guideline for children with abdominal pain.
