There are about 1802 clinical studies being (or have been) conducted in Puerto Rico. 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.
Background & Purpose: Energy drinks consumption continues to grow since its appearance in the United States in 1997. Available evidence indicates that caffeine, their main ingredient, can alter the central nervous system (CNS). However, it is unknown how energy drinks adjust the CNS postural control mechanism. The purpose of this study was to investigate how energy drinks can affect postural control after sensory perturbations during stance. Methods: 20 healthy adults, (11 males; 9 females) averaging 26.1 years of age, stood on a pressure mat, which measured center of pressure (CoP), anteroposterior (AP) and mediolateral (ML) postural sways during eight different balance tests (BALT's). BALT's were designed to alter or cancel the systems involved in postural control: visual, vestibular and somatosensory. Subjects were randomly assigned to a caffeine group and an energy drink group. MANOVA analysis was performed for all variables of interest.
A randomized placebo-controlled trial in individuals with Parkinson's disease dementia to evaluate the safety and efficacy of three doses of study drug LY3154207 in participants with mild-to-moderate Parkinson's disease dementia treated for 12 weeks.
This is phase 3b study seeks to evaluate the safety and efficacy of elagolix in combination with estradiol/norethindrone acetate for the management of heavy menstrual bleeding associated with uterine fibroids in premenopausal women. This study is double-blinded in the first year and an open-label in the second year.
The study compares 2 medicines for type 2 diabetes: fast-acting insulin aspart (a new medicine) and NovoRapid®/NovoLog® (a medicine doctors can already prescribe). Fast-acting insulin aspart will be tested to see how well it works and if it is safe. Participants will get either fast-acting insulin aspart or NovoRapid®/ NovoLog® - which treatment you get is decided by chance. Both medicines will be taken together with insulin degludec. Participants will need to take 1 injection 4 times every day (all insulins will be provided in pens). The study will last for about 8 months (34 weeks).
The purpose of this study is to compare the incidence of Zika virus (ZIKV) infection among pregnant women with and without Human Immunodeficiency Virus (HIV) infection and to determine the risk of adverse maternal and child outcomes associated with ZIKV/HIV co-infection across clinical sites in the continental United States (U.S.), Puerto Rico (P.R.) and Brazil.
Specific Aim: Implement an evidence-based diabetes prevention pragmatic trial for high risk pre-diabetic individuals of Caribbean-descent to reduce the incidence of diabetes. Hypothesis: This study seeks to test the hypothesis that implementation of a lifestyle intervention, with escalation to Metformin therapy will lower the incidence of diabetes among the highest risk pre-diabetic individuals of Caribbean-descent.
The purpose of this study is to compare LY900014 to insulin lispro, both in combination with insulin glargine or insulin degludec, in participants with type 2 diabetes (T2D).
The main purpose of this study is to evaluate the efficacy of the study drug LY900014 compared to insulin lispro, both in combination with insulin glargine or insulin degludec, in adults with type 1 diabetes (T1D).
The objective of this study is to evaluate safety and efficacy of elagolix in the management of moderate to severe endometriosis-associated pain in adult premenopausal female subjects including the safety and efficacy of elagolix in combination with concomitant hormonal add-back therapy.
A study to evaluate the efficacy and safety of glecaprevir(GLE)/pibrentasvir(PIB) in treatment-naïve participants with chronic hepatitis C virus (HCV) genotypes 1-6 infection and with an aspartate aminotransferase to platelet ratio index (APRI) of less than or equal to 1.
