There are about 30 clinical studies being (or have been) conducted in Trinidad and Tobago. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This was an observational study aimed to screen patients with cardiovascular disease for depression in Trinidad and Tobago in a tertiary center and to determine if there is a significant association between patients with symptoms of depression and other comorbidities. Patients (N=1203) were randomly selected from the outpatient cardiology clinics at the Eric Williams Medical Sciences Complex. After fulfilling the inclusion criteria and informed consent were obtained, they were given the case report form which included the Patient Health Questionnaire 9.
The aim of this study was to determine the prevalence of clopidogrel resistance among a selected group of patients undergoing elective percutaneous coronary intervention and to observe whether there was any south-Asian (Indo-Trinidadian) predilection for HPR considering the well-established epidemiologic trends for accelerated CAD within this subgroup.
Hypothesis: Trimetazidine improves Clopidogrel response in patients. • The investigators postulate that the inhibition of platelet aggregation in response to Clopidogrel may be accentuated by Trimetazidine, i.e. Trimetazidine enhances Clopidogrel response. Null Hypothesis: There is no difference in Clopidogrel response in patients with stable coronary artery disease with adjunctive Trimetazidine.
In this prospective observational study the investigators will report on 20 male subjects with proven WHO-classification Zika infection. These subjects will be followed up for a maximum of 12 months to observe the presence, viral load and infectivity of Zika virus (ZIKV) in semen over time.
The Eastern Caribbean Health Outcomes Research Network (ECHORN) is a collaborative research study that examines the lifestyles, eating habits, and health behaviors associated with cancer, diabetes and heart disease in adult men and women living in the Eastern Caribbean.
Fibroids are common in the West Indian population (30-40% of reproductive women).Fibroids are benign growth in the womb or uterus and in order to preserve the fertility of women they, require an operation called myomectomy or shelling out of the fibroid. This procedure can be associated with large blood loss. In current practice some obstetricians use a gonadotropin releasing hormone agonist prior to the operation to reduce blood loss. Gonadotropin releasing hormone agonist is used in current gynaecological practice to treat women with heavy periods. In this study the investigators randomised women to either 2 or 3 doses of the gonadotropin agonist prior to their operation and no treatment. The intraoperative blood loss was measured. The study hypothesis: To determine whether administration of gonadotropin releasing hormone agonist prior to myomectomy reduces intraoperative blood loss.
The investigators previously established that there was a high burden of disease among all categories of staff at the University of the West Indies, St. Augustine and in many ways, this group is typical of the working class of the Caribbean population. Many had poor lifestyle behaviors, 23.8% had Metabolic Syndrome (MS) with many having one or more MS components. Since most time is spent at work, the workplace is understandably the most logical location to address issues pertaining to health, disease prevention and wellness and on-site programs have yielded many health and other benefits to employees and employers alike. Onwards of the 1980s, numerous studies have been done on work-site intervention programs and these have shown that if a company is able to identify employees at risk for developing health problems and then intervene, health risks and the resulting medical problems are reduced. Such a program, if tailored to meet the needs of participants, may yield similar benefits among the staff of the University of the West Indies.
The purpose of this study is to assess the extent of and sources of variation in the glycaemic index values of foods measured by different laboratories around the world.
The purpose of this study is to determine whether dietary lycopene supplementation lowers serum prostate specific antigen(PSA) in men with high grade intraepithelial neoplasia (HGPIN).
The purpose of this study is to test how the body's immune system responds to the vaccine ALVAC-HIV vCP1452 and to determine if the vaccine is safe when given alone and with MN rgp120. HIV infection and AIDS have no cure, in spite of recent advances in anti-HIV drugs. Many worldwide populations cannot afford the antiviral treatments for infected people. HIV vaccines offer hope for disease prevention. In this trial, 2 experimental HIV vaccines called ALVAC vCP1452 and MN rgp120 will be given to volunteers in Haiti, Brazil, Peru, and Trinidad and Tobago. The study will determine how volunteers' immune systems respond to the vaccines. (This protocol has been changed by adding new international sites.)
