NCT ID: NCT06042543 Recruiting - Cervical Cancer Clinical Trials

Novel, One Stop, Affordable, Point of Care and AI Supported System of Screening, Triage and Treatment Selection for Cervical Cancer in LMICs

EASTER
Start date: December 9, 2023
Phase:
Study type: Observational

Artificial intelligence (AI) is fast gaining reputation as a highly promising solution for cervical cancer screening. AI-based detection of cervical neoplasias is named automated visual exam (AVE) by the National Cancer Institute, USA. The investigators propose to develop and evaluate the performance characteristics of a novel AI system to both screen and triage women as well as help in treatment decision making. AI will analyse infrared spectroscopic signals derived from urine samples of unscreened women for the presence of high-risk human papillomavirus (hr-HPV). Our preliminary study has shown that spectroscopy can detect hr-HPV in urine. For screen-positive women the AI will interpret a set of cervical images captured with a high-quality devoted camera to detect high grade cervical precancers and cancers and to determine the type of transformation zone (TZ) (helps in treatment decision). The prototype device for image capture and the AI algorithms are already developed by us. The technologies will be further improved in part 1 (initial 2 years) and validated in part 2 (subsequent 3 years). During Part 1, the investigators will analyse urine samples collected from 1100 women at multiple screening clinics in Zimbabwe for the presence of hr-HPV using spectroscopy and use the signals generated to improve the AI algorithm. In this part the investigators will also assess the concordance between hr-HPV detection in urine samples using spectroscopy and cervical human papillomavirus (HPV) detection using a validated HPV test. The cervical image recognition device and the AI algorithm will be further improved during part 1 by collecting more images from hr-HPV positive and negative women. AI will also be trained to interpret the cervical images to determine the TZ type. In part 2 total 2100 women will be screened in Zimbabwe with AI-supported spectroscopic analysis of urine to detect hr-HPV and a validated HPV test to evaluate and compare their sensitivity and specificity to detect histology-proved high grade cervical precancers and cancers. The sensitivity and specificity of AI-supported detection of cervical neoplasias on cervical images will be evaluated to triage the HPV positive women. The accuracy of AI to determine TZ type will be compared with expert opinion. During the field validation part (part 2), the investigators will also conduct a cost analysis and compare cost of our approach to current standard Zimbabwean practice. The International Agency for Research on Cancer- World Health Organization WHO (IARC-WHO) has partnered with The Neo Sense Vector Company (NSV), Delaware, USA (industry), The Engineering Department, Lancaster University, Lancaster, UK and The University of Zimbabwe, College of Health Sciences, Harare, Zimbabwe to implement this study focusing on innovation that will greatly contribute to the global elimination of cervical cancer, a WHO priority.

NCT ID: NCT06007105 Recruiting - Schizophrenia Clinical Trials

SUCCEED Africa: Support, Comprehensive Care and Empowerment of People With Psychosocial Disabilities

SUCCEED
Start date: July 18, 2023
Phase: N/A
Study type: Interventional

Although psychotic disorders typically affect less than 1% of the population, they are a significant cause of disability worldwide. Psychotic symptoms such as hallucinations, delusions and suicidal ideation can be profoundly disturbing, and negatively impact daily living. However, the social consequences of psychosis are often even more troubling than the symptoms. For example, people with psychosis have a high risk of experiencing violence, poverty, homelessness, incarceration, and unemployment, among other adverse outcomes. There is a need for a range of accessible, appropriate interventions for people with psychosis to be delivered to those in the most vulnerable situations, including in low-resource settings in sub-Saharan Africa. A systematic review recently carried out as part of the formative research for SUCCEED identified 10 studies evaluating the impact of interventions for people with psychosis in Africa, most of which had a strongly clinical focus. The review concluded that there was a need for further research involving people with lived experience of psychosis in designing and evaluating holistic interventions that meet their diverse needs, within and beyond the health sector. SUCCEED Africa is a six-year Health Research Programme Consortium (RPC) that has brought together people with lived experience of psychosis and people with professional experience (researchers, clinicians) from four African countries (Malawi, Nigeria, Sierra Leone, Zimbabwe) to co-produce a community-based intervention for psychosis, using a Theory of Change-driven approach. The SUCCEED intervention takes the World Health Organisation's (WHO's) CBR Matrix as a point of departure to consider the multifaceted needs of people living with psychosis and other psychosocial disabilities, and how best to meet these needs by mobilising the resources of individuals and families affected, as well as their broader communities. This protocol describes a pilot study in which the SUCCEED intervention will be delivered and evaluated on a small scale, in preparation for a larger multi-country research evaluation using more rigorous methods, including randomised controlled trials in Nigeria and Zimbabwe and observational studies in Malawi and Sierra Leone, respectively. The main outcome of interest is change in subjective quality of life among participants with lived experience of psychosis who are offered the intervention over a four-month follow up period.
