Filter by:It is a cluster randomized control trial to assess the effectiveness of the cervical cancer stigma reduction intervention on cancer stigma score and cervical cancer screening uptake in Nepal
cervical cancer is the fourth most frequent cancer in women worldwide and in Brazil, it occupies the third position for the triennium 2020/2022, with a high mortality rate and maintained in the last 10 years. It is associated with persistent human papillomavirus (HPV) infection. Primary prevention can be accomplished through vaccines that prevent HPV infection of the epithelial cells of the cervix. Secondary prevention in screening for precursor lesions through periodic repeat cervical sampling in a population of asymptomatic women. Women with abnormal cytology are more likely to have pre-invasive or invasive lesions and are referred for further testing, colposcopy. Colposcopy identifies suspicious areas and guides the best site for biopsy. In the situation of negative colposcopy and abnormal cytology, suspicion for high-grade lesion (HSIL). It recommends further investigation of the endocervical canal before the possible excisional procedure and obtaining an additional canal sample by brushing or curettage. However, to date, there is no consensus and studies lack consistent results on which is the best method for further investigation of the endocervix. Objectives: To compare the performance of additional strategies in the investigation and detection of precursor or invasive lesions in the endocervical canal in women with abnormal cytology (ASC H+) and with initial colposcopy without suspicious images.
In Belgium, Periodic Health Screenings (PHS) are obliged by law for several occupations, including safety functions, jobs with heightened vigilance, work that involves physical, biological or chemical agents or tasks that are an ergonomic or mental burden. Scientifically it remains an open question whether these screenings guarantee the prevention of later health problems or problems with functioning at work. The objective of this study is to compare the cost-effectiveness of PHS with an online health screening tool with selective follow-up. In five Flemish hospitals, the employees eligible for PHS (exempting frequent exposure to ionizing radiation, preparation of cytostatics, or exposure to carcinogens, mutagens, or reprotoxic substances) are randomly assigned to a control group (receiving classical PHS at the occupational physician), or an intervention group (e-tool with selective follow-up by the physician). In the intervention group, 20% of the employees is seen by the occupational physician, based on their responses to the questionnaire. The intervention- and control group complete the questionnaire three times: before the study start (June 2019), in February 2020, and in September 2020. The study ends in March 2021. The survey is developed as part of the study. On the one hand it contains questions for the cost-effectiveness analysis: health care use, absenteeism and presenteeism, and health literacy. On the other hand, a validated questionnaire is developed based on a systematic review of existing validated and reliable instruments, a Delphi panel of occupational physicians, and a pilot- and field study that test the reliability and validity of the survey (and its referral to the occupational physician). For the latter, the employees' health, occupational risks, work ability, and lifestyle (alcohol abuse, drug abuse, physical activity, and nutrition) are surveyed. Access to the occupational physician remains guaranteed by means of an additional question ("Do you wish to discuss the results of your survey with the occupational physician?") and as spontaneous consultations with the occupational physicians remain possible before, during, and after the trial. The survey platform Qualtrics is used for data collection. Researchers have no insight in personal data, nor the medical files of employees, and only analyse the coded data from the surveys. Invitations for the survey are sent by the occupational physician. The coded questionnaires are saved on a KU Leuven survey, following the ISO-9001-procedure and the legal data storage period. The employer has no insight in the data. The study is performed by Jonas Steel, supervised by prof. dr. Jeroen Luyten and prof. dr. Lode Godderis, and financed by the Belgian Association for Occupational Physicians, and three external services for prevention and protection at work: IDEWE, Liantis, and Mensura.
Older patients with cancer constitute a heterogeneous group with varying comorbidity; therefore, geriatric assessment with initial screening is recommended. The Geriatric 8 (G8) has been established as a promising screening tool. Currently, there are no guidelines for oncogeriatric screening in older cancer patients in Denmark. We hypothesize that by screening persons age 70 years or more with newly diagnosed cancer, with the G8, we can assess the prognostic value and identify a subgroup of patients who will benefit from a CGA. Aims: - Determine whether Danish cancer patients, with a G8 score of ≤14, experience poorer quality of life (QoL), receive less recommended standard cancer treatment, experience more treatment-related toxicity, stop treatment earlier, and experience shorter survival than patients with a G8 score >14. - Ascertain whether the standard G8 cut-off score of ≤14 is the most relevant cut-off score, with respect to treatment adherence, treatment-related toxicity, QoL, and survival, when focusing on the older Danish cancer patient population. - Establish whether the performance and prognostic value of the G8 can be strengthened through the addition of a functional measure, the 30-second chair stand test (30-CST), and/ or the handgrip strength test (HGST). - Evaluate the prognostic value of the modified Geriatric 8 (mG8) Methods: A prospective, descriptive study of all outpatients with newly diagnosed solid tumors at the Department of Oncology, Odense University Hospital, age 70 years or more. Patients will be screened with the G8, mG8, 30-CST, HGST, and QoL questionnaires at baseline with subsequent one-year follow-up, to determine the prognostic value of the G8 and the mG8. An initial two-month pilot study will help determine inclusion rates and highlight necessary practical adjustments to ensure optimal study participation. Baseline characteristics will be compared with descriptive statistics. Our primary endpoint; Global Health status/ QoL (EORTC QLQ-C30 & QLQ-ELD14), and secondary endpoints; treatment adherence, and treatment-related toxicity, will be assessed using logistical regression; while secondary endpoints; overall survival, cancer-specific survival, will be assessed using the Kaplan Meier analysis and Cox proportional hazard models. Post hoc diagnostic performance analysis will be conducted to determine the optimal G8 cut-off and whether functional measures (30-CST and HGST) can enhance screening accuracy.
Screening at-risk subjects with low-dose computed tomography (CT) efficiently reduces lung cancer specific mortality. However screening efficiency relies on the at-risk population's criteria definition and its participation rate to the screening. In France, there are concerns regarding the participation rates to national cancer screening that are quite low (around 50% and 32% of the eligible population for breast cancer and colorectal cancer respectively). Before organizing national lung cancer screening it is then crucial to determine the factors impacting the at-risk subjects willingness to participate in lung cancer screening. The Lyon University Hospital is the second biggest hospital in France with more than 23,000 employees distributed among more than 160 professions representing every level of education or working conditions. Its population is heterogeneous and wide enough to perform a prevalence study assessing the willingness to participate among the at-risk population. ILYAD is a prospective study performed by anonymous questionnaires that will be submitted to the 23,000 employees of the Lyon University Hospital. The study main objective is to evaluate the at-risk population presence in the Lyon University Hospital population, as defined by NELSON criteria and selection criteria for lung cancer screening (PLCOm2012 scoring), and its willingness to participate to a lung-cancer screening with low-dose CT. This might help further efficient national lung cancer screening campaign organization.
First-degree relatives of patients with melanoma have a greater risk of developing melanoma. Patients are advised orally to inform their first-degree relatives that they should protect their skin from UV radiation and ask for a skin examination from a general practitioner or dermatologist. The study will evaluate the effectiveness of a written sheet in addition to the usual oral counselling to increase acceptance of skin examination by the first-degree relatives. If effective, written counselling provided to the patient for relatives should be recommended and generalized.
The purpose of this study is to determine whether colorectal cancer diagnosed by screening (primary screening colonoscopy, colonoscopy after immunochemical based faecal occult blood test) has more favourable clinical-pathological characteristics than colorectal cancer diagnosed for symptoms. We aimed to compare these two groups of patients at the time of diagnosis and confirm the efficiency of the screening programme.
The purpose of this research study is to test the effectiveness of telephone-based early childhood developmental screening and care coordination, compared to usual care in a primary care pediatrics clinic. Investigators randomized 152 participants to one of two study arms, with the intervention families receiving developmental screening over the phone, and control families receiving usual care with their pediatricians.
Colonoscopy aims to investigate the entire colon by advancing the colonoscope tip from the rectum to the cecum, a process called cecal intubation. Cecal intubation may be difficult for different reasons, and features of the colonoscope and the use of imaging devices may influence the success rate. We want to compare the performance of a new colonoscope with novel features including gradual stiffness with that of a colonoscope supplied with a magnetic endoscope imaging (MEI) device. The hypothesis is that the performance of the new instrument is non-inferior to the MEI system.
The purpose of this study is to determine the diagnostic and management concordance of face-to-face dermatologist versus a store-and-forward teledermatologist at a skin cancer screening event. The investigators' hypotheses include the following: 1. Compared to in-person assessment, store-and-forward teledermatology assessment will result in adequate diagnostic concordance. 2. Compared to in-person assessment, store-and-forward teledermatology results in adequate management concordance. 3. The sensitivity and specificity of store-and-forward evaluation to detecting lesions that are either premalignant or malignant will be similar to that of in-person evaluation.
