There are about 15 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.
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 compare the effects of ICA-17043 to placebo with or without hydroxyurea (an oral drug used for treatment of sickle cell disease) in patients with sickle cell disease who have had 2 or more acute sickle-related painful crises requiring a visit to a medical facility within the past 12 months.
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.)
