Filter by:The primary purpose of the proposed study is to validate our previously developed predictive model for adults with obstructive sleep apnea using (i) clinical data from multiple large academic centers, (ii) a longer follow-up period, and (iii) an extended definition of outcomes of interest. The TOH sleep database was created as a part of the project: "Validation of provincial health administrative data algorithms to identify patients with obstructive sleep apnea (OSA): Feasibility project". Protocol ID: 20170591-01H (AMENDMENT APPROVED on December 19, 2018) to be used for future clinical, research, educational and quality improvement purposes.
COPD is underdiagnosed and spirometry is not widely available in primary care settings. This study explore the value of PUMA´s questionnaire in a case finding strategy to detect patients to perform spirometry in a real world scenario of primary care health venues.
The purpose of this study is to explore the perinatal risk factors of preterm birth in China.
To identify risk factors for mortality in patients with interstitial lung disease receiving mechanical ventilation.
Chronic pancreatitis (CP) is a disease characterized by inflammation and their replacement by fibrotic tissue. The destruction of pancreatic function and structure are the main complications. This retrospective-prospective, multicenter, cohort study was conducted. This study aimed to observe the natural history of CP in China, analyse the risk factors for CP complications, and establish individual predictions.
Atrial fibrillation (AF) is the most common arrhythmia affecting over 3 million Americans and about 33.5 million individuals globally. The lifetime risk of developing AF is 1 in 4 for adults over age 40 years. AF is associated with a major medical and socioeconomic burden including high cost, increased risk of stroke, heart failure, dementia, myocardial infarction, and death. Numerous studies have demonstrated that modifiable risk factors including hypertension, obesity, sleep apnea, diabetes, and sedentary lifestyle predict the development of AF. Recent studies have reported that secondary prevention interventions through aggressive risk factor modification can reduce the burden of AF. Structured, physician and nursing-led interdisciplinary AF programs have been shown to improve patient adherence to guideline recommendations and improve long term prognosis. Previous data, however, are derived mainly from white European and Australian cohorts and it is unclear whether such interventions can be effectively implemented in a racially diverse, safety net hospital in the U.S. This study is a randomized hybrid implementation-effectiveness study designed to investigate feasibility and effectiveness of an evidence-based innovative AF program, focusing on risk factor modification and AF education in a racially mixed population receiving care in a safety net hospital.
The purpose of this study was to cross-sectionally evaluate nutritional status and the metabolic syndrome in a sample of school-age children 10-15 years of age from 20 public schools in Santiago, Chile. In addition, the investigators retrospectively assessed the association of those variables with perinatal variables (birth weight, birth length, and gestational age at delivery).
Myelodysplastic Syndromes (MDS) are characterized by quantitative and qualitative bone marrow failure and by a disorder of the medullary production which is a pre-leukemic state which can evolve into acute myeloid leukemia. The risk of leukemic transformation is estimated by the score IPSS (International Prognostic Score System). We distinguish the MDS of low risk (IPSS<1) and those of high risk of leukemic transformation (IPSS=1,5). Besides the risk of leukemic transformation, MDS much be complicated of infections which could be life-threatening. The risk of developing first infection after the diagnosis of MDS of high risk is probably influenced by anamnestic (disease duration, comorbidities), clinical (veinous central catheter, previous hospitalization), biological (neutropenia, lymphopenia, serum ferritin) and therapeutics (demethylating agent, lenalidomide, erythropoietin, G-CSF, transfusions, anti-infectious preventive treatment) factors. Their identification will allow for improved targeting of the population which is is likely to benefit from anti-infective prophylaxis Primary objective is to identify risk factors associated with first acute episode of infection in patients with MDS, by comparing index cases and matched control cases who did not develop infection episode since diagnosis. Secondary objectives are to explore nature and severity of infectious episodes, number of recurrences during 1 year of follow up and survival at 6 and 12 months
The primary purpose of this trial will be to test the effectiveness of CHANGE intervention to increase physical activity, improve diets, reduce obesity and reverse Metabolic Syndrome among adult patients identified as at risk for cancer due to diet and physical activity behaviours when implemented in typical primary care settings within the Alberta context.
Constipation is a symptom based disorder with a prevalence of 15% in the adult population and its management remains challenging. Although not life threatening, constipation is associated with impaired quality of life, increased healthcare costs and excess work absenteeism. Constipation represents a heterogeneous disorder with a multifactorial pathogenesis. Several risk factors have been suggested to lead to the condition and are divided in 3 main categories: a) physiological, b) environmental and c) demographic. To date, there is lack of large epidemiological studies on proposed aetiological factors of constipation, especially studies assessing all proposed risk factors of constipation together. The overall aim of this study is to investigate the multidimensional (physiological, environmental and demographic) predictors of constipation with the use of a multivariate analysis statistical model. This is a large single centre case control study comparing constipated adults with healthy individuals matched for age, gender and ethnicity. The duration of the study is 2 weeks in total and includes a screening visit, a 2 week run-in period and a baseline visit at the end of the run-in period. Transit time between constipated and healthy individuals is assessed at baseline visit. Differences in gastrointestinal symptoms, dietary intake as well as differences in stool output (e.g. stool frequency and consistency) between constipated and healthy individuals are assessed over the baseline period (the week before the baseline visit). Differences in female sex hormone levels as well as stool markers and markers of fermentation (e.g. fecal water, stool pH, short chain fatty acids) between constipated and healthy individuals are assessed at baseline visit. Furthermore, differences in environmental measures (physical activity, anxiety, smoking) and differences in demographic measures (age, gender, body mass index) between patients suffering from constipation and healthy individuals are also assessed at baseline visit.
