Filter by:By collecting non-image medical data of women undergoing cervical screening in multiple centers in China, including age, HPV infection status, HPV infection type, TCT results, and colposcopy biopsy pathology results, a multi-source heterogeneous cervical lesion collaborative research big data platform was established. Based on artificial intelligence (AI) machine learning, cervical lesion screening features are refined, a multi-modal cervical cancer intelligent screening prediction and risk triage model is constructed, and its clinical application value is preliminarily explored.
Preoperative risk assessment (an evaluation of overall health before surgery) is important to determine the overall risk of mortality and complications for patients undergoing major abdominal surgery to allow the appropriate allocation of sparse hospital resources. The current gold standard for preoperative assessment is cardiopulmonary exercise testing (CPET). CPET is, however, not available in all centres that perform major surgery, it is a costly test, and therefore only high-risk patients are tested. Finding new ways of conducting preoperative assessment could improve overall surgical safety, patient experience and reduce cost. The preoperative use of remote vital signs monitoring can provide important information about the patients' fitness and overall health and may be used for preoperative assessment. This study will use a remote monitoring patch to monitor patients' vital signs before surgery. The aim is to evaluate the utility and patient acceptability of the remote monitoring system and the feasibility of a randomised controlled trial of this type of assessment. Additionally, the study will assess the correlation between the data captured by the remote monitoring system and the CPET results to evaluate the remote monitoring system's ability to predict risk of surgery. The study will take place in Leeds Teaching hospitals. Adult patients undergoing major abdominal surgery that require CPET before surgery are eligible. Participants will be monitored at home with the patch monitor for 3-5 days before surgery, in addition to their planned preoperative assessment. During remote monitoring, patients will be asked to complete questionnaires on their general health and experience using the patch paired with the mobile phone as part of the monitoring system. Clinical data from the electronic hospital records and general practitioner records available on the trust system will then be collected after surgery to assess complications and calculate risk scores.
The primary objective of this study is to investigate the impact of preoperative focused transthoracic ultrasound (FOCUS) on intraoperative hypotension and postoperative complications in hip fracture surgery. Our hypothesis is that a preoperative FOCUS along with a hemodynamic optimization protocol will reduce the occurrence of intraoperative drops in blood pressure and post-operative complications.
Validation of Clinical Prediction Model for Venous Thromboembolism Following Neurosurgery: A Multicenter, Prospective, and Cohort Study
The goal of this observational study is to establish and verify the Chinese version of surgical risk assessment system and explore its clinical application. The main questions it aims to answer are: The process of establishing a Chinese version of surgical risk assessment system; What is the accuracy of the system; How can the system be used in clinic; How does this system compare with other systems (such as NSQIP). Participants will comprehensively collect the general information, examination and pathological information of the patients, using machine learning and artificial intelligence methods for data processing. Finally, the Chinese version of the surgical risk assessment system will be established. After the system is established, investigators will evaluate the accuracy of the system and compare it with other related systems.
Surgical site infections (SSI) are serious complications accounting for 20% of all the healthcare-associated infections and are considered the second most frequent type of hospital-acquired infection in Europe and the United States. SSI after cardiac surgery is associated with delays to patient's discharge, readmissions and re-operations; and can result in increased hospital costs for staffing, diagnostics and treatment. Risk assessment has been identified as potentially useful intervention in SSI prevention and in identifying at risk populations who may benefit from specific interventions to reduce this possible complication of cardiac surgery. However, there is currently a lack of evidence as to which risk tools are the most valid and reliable to be used in clinical practice. The investigators developed and locally validated the Barts Heart Centre Surgical Infection Risk (B-SIR) tool to include patients with various types of cardiac surgeries and found that the B-SIR tool is a better tool in predicting SSI risk compared with the existing cardiac risk tools in the study population. However, various literatures recognised that the predictive performance of a risk model tends to vary across settings, populations and periods. Hence, the investigators aim to do a multi-centre validation of the newly developed B-SIR tool and apply all the other tools (Australian Cardiac Risk Index and Brompton and Harefield Infection Score) to identify what tool performs best that can potentially be use for the UK population. Further, the outcome of the study will be beneficial to future cardiac surgery patients to assess their risk of developing SSI and help identify those patients who may benefit from specific interventions. Existing patients' data, which will be anonymised, from the participating cardiac centres will be utilised to analyse and compare the performance of each risk tools.
Outdoor play is important for children as it can promote healthy social and physical development, emotional well-being, self-confidence, risk management and overall physical activity. Yet, opportunities for outdoor play have been decreasing across generations due to perceptions that it is dangerous and unnecessary. Early childhood educators (ECEs) and administrators are struggling to provide children with high quality and stimulating outdoor play time. To help ECEs and administrators, the investigators have developed a Risk Reframing (RR) digital tool, https://outsideplay.ca, which is underpinned by social cognitive theory (SCT) and health behaviour change techniques. The aim of the current study is to test the efficacy of the RR digital tool in: 1) increasing ECEs/administrators' tolerance of risk in play; and, 2) attaining their behavior change goal in promoting children's outdoor play at their early childcare center. The investigators will conduct a single-blind (researchers and outcome assessors) randomized controlled trial and will obtain complete data on at least 206 early childhood educators and administrators currently working in Canada. The RR digital tool is designed for a one-time visit and includes three chapters of self-reflection and experiential learning tasks. The control condition consists of reading the Position Statement on Active Outdoor Play, a 2-page information sheet on children's active outdoor play. Primary outcome is increased tolerance of risk in play, as measured by the Tolerance of Risk in Play Scale - teacher version. Secondary outcome is self-reported attainment of a behaviour change goal that participants set for themselves. The investigators will test the hypothesis that there will be differences between the intervention and control conditions with respect to tolerance of risk in play and goal attainment.
Arrhythmias are considered a prominent phenomenon in pulmonary hypertension (PH) as the disease progresses. According primarily to retrospective studies with up to 24 hours of monitoring, supraventricular tachycardias (SVT) can be found in 8-35% of patients, with significant impact on survival. Furthermore, a few prospective studies to date deploying short-term monitoring (10 minutes-24 hours) have revealed lower heart rate variability (HRV) in patients with pulmonary arterial hypertension (PAH). In ASPIRE arrhythmias and heart rate variability is being assessed via long term monitoring. Currently the the loop-recorder is considered the gold standard for long-term continuous cardiac montoring. A non-invasive continuous monitoring could be of a great benefit for the patients, and could potentially contribute to treatment optimization. The study will assess apple watches as a non-invasive tool compared to to the loop recorder, which is considered as the current gold standard. Additionally, the study seeks to assess apple watches for monitoring as an independent wearable for risk assessment in PH.
The RAD study is a longitudinal study to prospectively characterize the biological mechanisms of resilience in adolescents and young adults at risk for developing depression. The study will capture biomarkers from the domains of socio-demographic and clinical data, cognitive and psychological assessments, fluid-based biomarkers, neuroimaging and EEG. Such biomarkers will compose a human biosignature of resilience and identify risk factors for depression, contributing to effective treatment selection or may represent moderators of response or non-response to treatments in subjects with depression. A cohort of 1,500 participants, age 10-24 will be recruited over a 5 year period. Participants will be followed for 10 years following an initial baseline visit. Study visits are conducted 4 times per year.
Children's risky play is associated with a variety of positive developmental, physical and mental health outcomes, including greater physical activity, self-confidence and risk management skills. Children's opportunities for risky play have eroded over time, limited by parents' fears and beliefs about risk, particularly among mothers. We have developed a digital and in-person workshop version of a tool to reframe parents' perceptions of risk. We examined whether the tool increased mothers' tolerance for risky play and influenced parenting behaviour change, in the short and long term, and whether these changes were greater than those in the control group. We conducted a single-blind (researchers and outcome assessors) randomized controlled trial and recruited a total of 410 mothers of children aged 6-12 years. The risk reframing (RR) digital tool is designed for a one-time visit and includes three chapters of self-reflection and experiential learning tasks. The RR in-person tool is a 45-90 minute facilitated workshop in which participants were guided through discussions of the same tasks contained within the digital tool. The control condition consisted of reading the Position Statement on Active Outdoor Play. Primary outcome was increased tolerance of risk in play, as measured by the Tolerance of Risk in Play Scale. Secondary outcome was self-reported attainment of a behaviour change goal that participants had set for themselves. We tested the hypothesis that there would be differences between the experimental and control groups with respect to tolerance of risk in play and goal attainment.
