Clinical trials

The goal of this clinical trial is to determine whether performing total knee replacement surgery (total knee arthroplasty, TKA) without a tourniquet is clinically equivalent to performing the procedure with a tourniquet in adults with symptomatic knee osteoarthritis. A tourniquet is commonly used during surgery to reduce bleeding and improve the surgeon's view. However, some studies suggest it may be associated with certain complications. It is currently unclear whether using a tourniquet meaningfully changes outcomes compared to not using one. This study aims to assess whether both approaches result in similar outcomes within a clinically acceptable range. The main question this study aims to answer is: Is total blood loss during surgery equivalent between TKA performed with a tourniquet and TKA performed without a tourniquet, within a predefined margin of ±100 mL? Additional questions include: Are surgical field quality, postoperative pain, functional recovery, and complication rates comparable between the two techniques? Researchers will compare: TKA performed with a pneumatic tourniquet TKA performed without a tourniquet to determine whether outcomes between the two approaches are equivalent rather than whether one is superior to the other. Participants will: Be randomly assigned to one of the two surgical groups using a computer-generated process Undergo standard total knee replacement surgery and routine perioperative care Have blood loss assessed during and after surgery Be monitored for pain, recovery of function, wound healing, and complications during hospital stay and follow-up visits This study is designed as a randomized controlled equivalence trial to determine whether both surgical approaches produce comparable outcomes within clinically acceptable limits, in a standardized local setting.

The purpose of this study is to determine the prevalence of neck and low back pain among physical therapy students enrolled at The University of the West Indies, Mona. It also aims to assess students' knowledge, attitudes, and practices regarding spine health and to evaluate the effectiveness of an eight-week standardised spine-specific exercise programme in reducing musculoskeletal pain and improving functional status among those reporting symptoms. The study will be conducted in two phases, beginning with a descriptive cross-sectional assessment of prevalence, followed by a prospective randomised controlled trial in which students experiencing neck and/or low back pain will be allocated to either a spine-specific exercise intervention group or a non-spine-specific exercise control group for comparative analysis of outcomes.

The purpose of this study is to determine the prevalence of neck and low back pain among full-time staff at the Faculty of Medical Sciences Teaching and Research Complex (FMSTRC), The University of the West Indies, Mona. It also seeks to assess staff members' knowledge, attitudes, and practices regarding spine health and to evaluate the effectiveness of an eight-week standardised spine-specific exercise programme in reducing musculoskeletal discomfort among those experiencing neck and low back pain. The study will be conducted in two phases using a descriptive cross-sectional design followed by a prospective randomised controlled trial, in which participants reporting pain will be allocated to either a spine-specific exercise intervention group or a non-spine-specific exercise control group for comparative analysis of outcomes.

The purpose of this study is to identify the prevalence of neck and low back pain in nursing students enrolled at the University of the West Indies, Mona; to assess their knowledge, attitude and practice of good spine health and to determine the outcome of a standardised spine exercise program on nursing students experiencing neck and low back pain, using a prospective randomised control design.

The goal of this clinical trial is to establish the efficacy of Cassia alata extract as a cream form in treating tinea versicolor (liver spots/shifting clouds). The main questions the study aims to answer are:• Does the use of this extract help resolve tinea versicolor better than no treatment? Does the use of this cream have significant side effects i.e, is it safe? Participants will be asked to treat a designated area while leaving additional areas untreated. 1-2 finger tip units of cream will be applied to the treatment site twice daily at least 8 hours apart. Participants will attend the trial clinic every 4 weeks for 12 weeks.

The purpose of this study is to identify the prevalence of neck and low back pain in medical students enrolled at the University of the West Indies, Mona; to assess their knowledge, attitude and practice of good spine health and to determine the outcome of a standardised spine exercise program on medical students experiencing neck and low back pain, using a prospective randomised control design.

This research aims to clarify the best way to perform subcutaneous tissue closure in overweight and obese patients undergoing caesarean section to reduce the occurrence of surgical site infections. This Study seeks to get some local perspective on the need for and type of subcutaneous fat closure in obese women undergoing cesarean section, thereby reducing Surgical Site Infection. This is a pilot; double- blinded randomized control trial, with balanced randomization (1:1) and parallel grouped study. The sample size calculated by Raosoft Sample Size Calculator Software determined that based on a margin of error of 5%, there would need to be 266 participants to give 90% confidence level to detect a significant difference between both arms of the study. Patients who are immune-compromised, those with anemia, requiring transfusion will be excluded from the study, also any mother who wishes not to participate. Patients will be reviewed 7 days post operatively. Wound complications will be identified by a questionnaire by telephone at 4 weeks and 3 months post operatively. Data will be collected from Specific closed answer questions. Data extraction sheet will be used to collect data for the patient. This information will be collected either from the docket, direct review or examination of the study participants. The research will be done at Victoria Jubilee Hospital. The Research will last six months.

Structural and functional changes in arteries are increasingly being recognized as significant features of sickle cell disease. This study aims to determine whether there are differences in arterial function parameters between children with sickle cell disease with normal and abnormal transcranial Doppler velocity. After informed consent is obtained, participants will have vascular, Transcranial Doppler, haematological and biochemical parameters measured. Researchers will compare children with sickle cell disease who have normal Transcranial Doppler velocity and no history of stroke with children with those who have an abnormal Transcranial Doppler velocity with or without a history of stroke to see if there are significant differences in arterial function parameters.
