Abstract
BACKGROUND Approximately a quarter of the global population experiences chest pain during their lifetime worldwide. Although largely non-life-threatening, many patients experience mental, physical, social, and financial consequences. AIM This study aimed to describe and determine the epidemiology and consequences of patients presenting with atypical chest pain (ACP). Method: Data were obtained from 102 participants, from a desired sample size of 166. The target population was patients who presented with ACP at the Accident and Emergency Department of a Teaching Hospital in Trinidad during a two-year period, from January 2021 to December 2022. The data collection instrument used was a 34-item online questionnaire. Data were analyzed using both descriptive and inferential statistical methods. RESULTS Participants were predominantly women (63.7%; n = 65), between 31 and 50 years of age (74.5%; n = 76), in full-time employment (n = 58; 56.9%), who lived with at least one person (90.2%; n = 92) at the time of the episode. Overall, 61.8% (n = 63) reported having a stressful life. Hypertension (30.4%; n = 31) and diabetes (18.6%; n = 19) were the leading comorbidities. Participants experienced mild to severe anxiety (53.9%; n = 55), moderate to severe depression (25.5%; n = 26), moderate stress (65.7%; n = 67), and loneliness (25.5%; n = 26). A stressful life was associated with, and was a predictor of, both anxiety and loneliness. No sociodemographic variables were associated with depression or stress. The most common self-reported consequences were "fear as a result of the pain" (68.6%; n = 69), "interruptions to daily life" (60.8%; n = 61), "reduction in time spent on hobbies" (62.7%; n = 63), and costly diagnostic/investigative tests (62.7%; n = 64). The majority of patients (52.9%; n = 53) reported reduced quality of life. The most common treatment prescribed was paracetamol (53.9%; n = 55) and exercise (23.5%; n = 24). CONCLUSION The study participants were mainly women, 31-50 years old, who had experienced anxiety, stress, or depression. They mainly experienced fear and self-reported a reduced quality of life.

Abstract
BACKGROUND Depression with diverse etiologies is exacerbated by chronic diseases, such as chronic kidney disease (CKD), coronary artery disease (CAD), cancer, diabetes mellitus, and hypertension. This study aimed to analyse depression, its associations, and predictors among patients attending the kidney clinic of a teaching hospital. METHODS Data were collected from 01 August 2017 to 30 September 2017 via face-to-face interviews and examination of the medical records of a convenience sample of 314 patients. The patients were categorised broadly as stages I and II with an estimated glomerular filtration rate (eGFR) > 60 mls/min/1.73 m2, and with stages III, IV, and V or GFR ≤ 60 mls/ min/1.73 m2 (or CKD). The Patient Health Questionnaire (PHQ)-9 was the data collection instrument for depression-related data. RESULTS Participants were predominantly male (n = 179; 57.0%), aged over 60 years (n = 211; 67.2%), Indo-Trinbagonian (n = 237; 75.5%), and with stages III, IV, and V CKD. The two leading comorbid conditions were hypertension (83.4%) and diabetes mellitus (56.1%). Of the 261 (83.1%) patients with recorded eGFR, 113 (43.3%) had Stage III CKD. The mean depression (PHQ-9) score was 13.0/27 (±9.15), with 306 (97.5%) patients diagnosed as having depression with the following severities: mild (n = 116; 37.9%), moderate (n = 138, 45.1%), moderately severe (n = 38; 12.4%), and severe (n = 14; 4.6%). Depression was independent of sex. Nine sociodemographic variables were associated with depression; however, 'level of education', was the only predictor of depression with greater severity associated with lower levels of education. eGFR was negatively correlated with the PHQ-9 scores (Pearson's correlation, r = -0.144, p = 0.022). At least 78.3% of the patients who self-reported no depression had clinical depression (moderate, moderately severe, or severe) PHQ-9 scores ≥ 10. CONCLUSION Depression was a significant comorbidity among patients with CKD, with the majority displaying clinical depression. "Level of education" was the only predictor of depression. Self-reported depression is an unreliable method for evaluating clinical depression.

Abstract
PURPOSE The determinants of quality of life for patients on renal replacement therapy vary across the world. The aim of this study is to determine the quality of life of patients on renal replacement therapy in Trinidad and Tobago and predictors thereof. PATIENTS AND METHODS This cross-sectional study took place over a 1-year period. Data were obtained from 530 out of 1383 patients meeting inclusion criteria (100 transplants, 80 peritoneal dialyses, 350 hemodialyses) using the survey instruments. Stratified random sampling with proportional allocation was used to select patients at hemodialysis centres. The Kidney Disease Quality of Life questionnaire (KDQOL-36), EuroQol and demographic questionnaires were administered via face-to-face interviews. SPSS24, STATA14 and MINITAB18 were used for descriptive and inferential data analysis. RESULTS Of the 530 patients, 52.5% were male, 37.5% were in the 56-65 years age group and 51.3% were of Indo-Trinbagonian descent. Hypertension (25.5%) and type 2 diabetes mellitus (62.0%) were reported as the main causes of kidney disease in the dialysis group. In the transplant category, chronic glomerulonephritis (45%) was the main aetiology of kidney disease. The KDQOL-36 domain scores and significantly associated variables included modality of renal replacement, Charlson's Comorbidity Index, ethnicity, income and employment status. Transplant patients had higher mean subcomponent Kidney Disease Quality of Life scores and performed better in the EuroQol than patients on dialysis. Patients on peritoneal dialysis had a better quality of life than hemodialysis patients. Among patients on hemodialysis, an arteriovenous fistula significantly impacted their quality of life. CONCLUSION Renal transplant recipients enjoy the best quality of life and health state among patients on renal replacement therapy in Trinidad and Tobago. Increasing patients' access to renal transplantation or peritoneal dialysis will markedly improve health status for the number of years of renal replacement therapy.

Abstract
BACKGROUND Patients with cardiac disease with or without depression may also have major physical and mental problems. This study assesses and compares the quality of life (QOL) of patients with cardiac disease with and without depression and accompanying comorbidities. METHODS A cross-sectional study was conducted with a convenience sample of 388 patients with cardiac disease. The 12-item Short-Form (SF-12)-patient was used to measure physical component scale (PCS) and mental component scale (MCS) QOL, and the Patient Health Questionnaire (PHQ-9) was used to measure depression. The Charlson Comorbidity Index was used to estimate 10-year survival probability. Descriptive statistics, analysis of covariance (ANCOVA), chi-square tests, and binary logistic regression were used for analysis. RESULTS The prevalence of minimal to mild depression was 65.7% [(95% CI (60.8, 70.4)] and that of moderate to severe depression was 34.3% [95% CI (29.6, 39.2)]. There was no significant association between the level of PHQ-categorised depression and age (p = 0.171), sex (p = 0.079), or ethnicity (p = 0.407). The overall mean PCS and MCS QOL was 32.5 [95% CI (24.4, 40.64)] and 45.4 [95% CI (44.4, 46.4)], respectively, with no significant correlation between PCS and MCS [r (Pearson's) = 0.011; p = 0.830)]. There were QOL differences among the five PHQ categories (PCS: p = 0.028; MCS: p ≤ 0.001) with both MCS and PCS decreasing with increasing depression. ANCOVA (with number of comorbidities as the covariate) showed a significant age × ethnicity interaction for PCS (p = 0.044) and MCS (p = 0.039), respectively. Young Indo-Trinidadians had significantly lower PCS than did Afro-Trinidadians, while the converse was true for MCS. Depression, age, and number of comorbidities were predictors of PCS, while depression, age, and sex were predictors of MCS. CONCLUSIONS Increasing severity of depression worsened both PCS and MCS QOL. Age and level of clinical depression predicted QOL, with number of comorbidities predicting only PCS and sex predicting only MCS. Efforts must be made to treat depression in all age groups of patients with cardiac disease.

Abstract
: Rabies virus (RABV) is the only lyssavirus known to be present within the Caribbean. The island of Trinidad, is richly diverse in chiropteran fauna and endemic for bat-transmitted rabies with low RABV isolation rates observed in this population. We aimed to determine the seroprevalence of rabies virus neutralizing antibodies (RVNA) in light of spatio-temporal and bat demographic factors to infer the extent of natural exposure to RABV in the Trinidadian bat population. RVNA titers were determined by the RABV micro-neutralization test on 383 bat samples representing 21 species, comprising 30.9% of local bat diversity, from 31 locations across the island over 5 years. RVNA was positively detected in 33 samples (8.6%) representing 6 bat species (mainly frugivorous) with titers ranging from 0.1 to 19 IU/mL (mean 1.66 IU/mL). The analyses based on a multivariable binomial generalised linear mixed-effects model showed that bat age and year of capture were significant predictors of seropositivity. Thus, juvenile bats were more likely to be seropositive when compared to adults (estimate 1.13; p = 0.04) which may suggest early exposure to the RABV with possible implications for viral amplification in this population. Temporal variation in rabies seropositivity, 2012-2014 versus 2015-2017 (estimate 1.07; p = 0.03) may have been related to the prevailing rabies epizootic situation. Regarding other factors investigated, RVNA was found in bats from both rural and non-rural areas, as well as in both hematophagous and non-hematophagous bat species. The most common seropositive species, Artibeusjamaicensisplanirostris is ubiquitous throughout the island which may potentially facilitate human exposure. The findings of this study should be factored into public health assessments on the potential for rabies transmission by non-hematophagous bats in Trinidad.

Abstract
BACKGROUND Cardiovascular disease remains the most common cause of death. However, effective and timely secondary care contributes to improved quality of life, decreased morbidity and mortality. This study analyzed the medical care of patients in a resource limiting country with a first presentation of acute myocardial infarction (AMI). METHODS A cross-sectional retrospective study was conducted on first time AMI patients admitted between March 1st 2011 and March 31st 2015 to the only tertiary public hospital in a resource limiting country, Trinidad. Relevant data were obtained from all confirmed AMI patients. RESULTS Data were obtained from 1106 AMI patients who were predominantly male and of Indo Trinidadian descent. Emergency treatment included aspirin (97.2%), clopidogrel (97.2%), heparin (81.3%) and thrombolysis (70.5% of 505 patients with ST elevation MI), but none of the patients had primary angioplasty. Thrombolysis was higher among younger patients and in men. There were no differences in age, sex, and ethnicity in all other treatments. Of the 360 patients with recorded times, 41.1% arrived at the hospital within 4 h. The proportion of patients receiving thrombolysis (door to needle time) within 30 min was 57.5%. In-patient treatment medication included: aspirin (87.1%), clopidogrel (87.2%), beta blockers (76.5%), ACEI (72.9%), heparin (80.6%), and simvastatin (82.5%). Documentation of risk stratification, use of angiogram and surgical intervention, initiation of cardiac rehabilitation (CR), and information on behavioral changes were rare. Electrocardiogram (ECG) and cardiac enzyme tests were universally performed, while echocardiogram was performed in 57.1% of patients and exercise stress test was performed occasionally. Discharge treatment was limited to medication and referrals for investigations. Few patients were given lifestyle and activity advice and referred for CR. The in-hospital death rate was 6.5%. There was a significantly higher relative risk of in-hospital death for non-use of aspirin, clopidogrel, simvastatin, beta blockers, and heparin, but not ACE inhibitors and nitrates. CONCLUSIONS Medication usage was high among AMI patients. However, there was very minimal use of non-pharmacological measures. No differences were found in prescribed medication by age, sex, or ethnicity, with the exception of thrombolysis.

Abstract
Background Over 60% of households (HHs) in Trinidad and Tobago (T&T) consume alcohol. These HHs were more likely to report illnesses, relationship problems, and behavioral problems with children. This study set out to determine what proportion of HHs were willing to support changes in specific policies, laws and regulations in a national alcohol campaign. Methods A cross-sectional convenience sample of HHs were surveyed from a random sample of enumeration districts (ED) in T&T. An interviewer-applied, field pre-tested de novo questionnaire had 5 domains and was developed over 1 1/2 years after an extensive literature review and consultation. Many of the WHO ‘best buys’ recommendations were included. Results One thousand six hundred ninety-five HHs (from 53 ED) responded from a total of 1837 HHs approached (response rate 92%). In a national campaign the following proportions of HHs would support: setting the legal age for drinking at 21 years (82.4%); restricting or banning alcohol advertising on TV and other media (73.1% and 54.4% respectively); banning all alcohol advertising at sports and cultural events (64.8%); banning radio stations playing songs with reference to alcohol use (71.3%); holding sellers of alcohol responsible for the amount of alcohol sold (79.5%); advocating that proof of age to be shown by persons buying alcohol (87.4%); placing more prominent warning labels on products displaying alcohol content (87.2%); placing more prominent warning labels on products showing harmful effects (88.5%); increasing taxes on alcohol sales (87.7%). Less than 50% of HH supported restrictions in density of outlets and reduction in opening times for alcohol outlets. Conclusions Many HHs in T&T are willing to support changes in policies around alcohol, including many of the policies shown by the WHO to be effective in reducing the harmful consumption of alcohol.

Abstract
Background The relative importance of coronary artery disease (CAD) risk varies globally. The aim of this study was to determine CAD risk factors for acute myocardial infarction (AMI) among patients in public health care institutions in Trinidad using a case–control type study design. Methods The sample comprised 251 AMI patients hospitalized between March 1, 2011 and April 30, 2012 and 464 age- and sex-matched non-AMI patients with no terminal or life-threatening illness and who did not undergo treatment for CAD. SPSS version 19 was used for data analysis that included chi-square tests, unadjusted and adjusted odds ratios (OR) and conditional multiple binary logistic regression. Results There was no difference in age between AMI and non-AMI patients (p = 0.551). Chi-square test revealed that clinical and lifestyle variables including stressful life, diabetes, hypertension, hypercholesterolaemia, ischaemic heart disease (IHD), a family history of IHD (p ≤ 0.001), smoking (p = 0.007) and alcohol consumption (p = 0.013) were associated with AMI; sex (p = 0.441), ethnicity (p = 0.366), age group (p = 0.826) and renal failure (p = 0.487) were not. Both unadjusted and adjusted (for age) ORs showed that the odds of hypertension, IHD and alcohol consumption were greater among AMI patients than among non-AMI patients for males; diabetes and IHD for females; and that the odds of a stressful life was greater among non-AMI patients and were the same for both groups with respect to sex, age > 45 years, hypercholesterolemia, renal insufficiency, and family history of IHD. Conditional multiple logistic regression showed that smoking [OR: 0.274, p ≤ 0.001, 95% CI for OR (0.140, 0.537)], a stressful life [OR: 2.697, p ≤ 0.001, 95% CI for OR (1.585, 4.587)], diabetes [OR: 0.530, p = 0.020, 95% CI for OR (0.310, 0.905)], hypertension [OR: 0.48, p = 0.10. 95% CI for OR (0.275, 0.837)] and IHD [OR: 0.111, p ≤ 0.001, 95% CI for OR (0.057, 0.218)] were the only useful AMI predictors. Conclusions Smoking, diabetes, hypertension, IHD and decrease stress are useful AMI predictors.

Abstract
AIM This study aimed to assess the impact of CYP2D6 and CYP2C19 variation on venlafaxine (VEN) at steady state in patients from Trinidad and Tobago of Indian and African descent with major depressive disorder. PATIENTS & METHODS Patients were phenotyped with dextromethorphan, genotyped for CYP2D6 and CYP2C19, and metabolic ratios for VEN obtained at 2-week intervals. RESULTS Of 61 patients, 55 were genotyped and phenotyped and 47 completed 8 weeks of VEN treatment. The majority of patients had metabolic ratios for VEN that were consistent with those for dextromethorphan and genotype-predicted phenotype using activity scores. One subject presented with a novel no-function allele, CYP2D6*99. No correlations were observed with CYP2C19 genotype. CONCLUSION CYP2D6 genotype analysis provides valuable information to individualize drug therapy with VEN.

Abstract
BACKGROUND To determine the patterns of alcohol use among households in Trinidad and Tobago (T&T) and to estimate the association between alcohol use and negative psychological, social, or physical events experienced by the household. METHODS A convenience sample of 1837 households across T&T. We identified bivariate correlates of alcohol use, and heavy episodic drinking using chi-square and t-test analyses and used multivariable logistic regression to estimate adjusted associations between household alcohol use and experiences within the past 12 months adjusted for sociodemographic covariates. RESULTS One thousand five hundred two households had complete data for all variables (82% response rate). Nearly two thirds (64%) of households included alcohol users; 57% of household that consumed alcohol also reported heavy episodic drinking. Households that reported alcohol consumption were significantly more likely to report illnesses within the households, relationship problems, and behavioral and antisocial problems with children. Among households where a member was employed, those who consumed alcohol were nearly twice as likely (OR = 1.98; 95% confidence interval (CI) 1.03, 3.82) to have a household member call in sick to work and 2.9 times as likely (OR = 2.9; CI 1.19, 7.04) to have a household member suffer work related problems compared with households who reported not consuming alcohol. CONCLUSIONS Approximately two thirds of households in T&T reported using alcohol. These households were more likely to report psychological, physical, and social problems. These findings would support efforts to enforce current policies, laws, and regulations as well as new strategies to reduce the impact of harmful alcohol consumption on households in T&T.

Abstract
Background Health care providers are often ill prepared to interact about or make acceptable conclusions on complementary and alternative medicine (CAM) despite its widespread use. We explored the knowledge, attitudes, and practices of health care providers regarding CAM. Methods This cross-sectional study was conducted between March 1 and July 31, 2015 among health care providers working mainly in the public sector in Trinidad and Tobago. A 34-item questionnaire was distributed and used for data collection. Questionnaire data were analysed using inferential and binary logistic regression models. Results Response rate was 60.3% (362/600). Responders were 172 nurses, 77 doctors, 30 pharmacists, and 83 other health care providers of unnamed categories (mainly nursing assistants). Responders were predominantly female (69.1%), Indo-Trinidadian (55.8%), Christian (47.5%), self-claimed “very religious” (48.3%), and had <5 years of working experience (40.6%). The prevalence of CAM use was 92.4% for nurses, 64.9% for doctors, 83.3% for pharmacists, and 77.1% for other health care providers. The majority (50–75%) reported fair knowledge of herbal, spiritual, alternative, and physical types of CAM, but had no knowledge of energy therapy and therapeutic methods. Sex, ethnicity, and type of health care provider were associated with both personal use and recommendation for the use of CAM. Predictors of CAM use were sex, religion, and type of health care provider; predictors of recommendation for the use of CAM were sex and type of health care provider. About half of health care providers (51.4%) and doctors (52%) were likely to ask their patients about CAM and <15% were likely to refer patients to a CAM practitioner. However, health care providers expressed interest in being educated on the subject. Doctors (51.9%) and pharmacists (63.3%) said that combination therapy is superior to conventional medicine alone. Less than 10% said conventional medicine should be used alone. Conclusion Knowledge about CAM is low among health care providers. The majority engages in using CAM but is reluctant to recommend it. Predictors of CAM use were sex, religion, and profession; predictors of recommendation for the use of CAM were sex and profession. Health care providers feel the future lies in integrative medicine.

Abstract
OBJECTIVE This cross-sectional study aimed to determine the prevalence, distribution and associated factors of dentine sensitivity (DS) among periodontitis patients in Trinidad. METHODS Sequential patients meeting the periodontitis criteria (BPE 4/4*) were included and completed a questionnaire on DS prior to a full periodontal examination. Clinically elicited symptoms of DS and presence of cervical tooth wear were recorded. RESULTS DS prevalence was 73.1% (n = 130; mean age 50 years). Mean number of sensitive teeth increased with increased severity of gingival recession. Most common initiating factors of DS were cold stimuli (70.5%), brushing (25.3%) and sour food (11.6%). Correlations were obtained for DS and race, toothbrush texture hardness, cervical tooth wear and gingival recession severity (P < 0.05; binary logistic regression). Cervical tooth wear was recorded in 46.3% of DS patients. Full-mouth plaque scores (FMPS) and full-mouth bleeding scores (FMBS) were statistically significantly (P < 0.05; Mann-Whitney U) test lower for DS versus non-DS patients. Patients reported a low usage (27.4%) and satisfaction (53.8%) rating for desensitizing agents. CONCLUSIONS The high prevalence of DS was comparable to other studies on periodontitis patients. Progressive periodontal disease and toothbrush abrasion were possible aetiological factors for DS in this study. Knowledge of local dietary practices and the role of acidic (sour) foods in eliciting DS may aid in management. The high prevalence of cervical tooth wear and the lower FMPS and FMBS among DS patients may reflect more aggressive tooth brushing. DS does not seem to be a limitation to plaque control in DS versus non-DS patients in this study.

Abstract
OBJECTIVE To determine the relative contribution of known high-risk human papillomavirus (HPV) genotypes to the occurrence of cervical cancers in Trinidad. METHODS The distribution of HPV genotypes in cases of invasive cervical squamous cell carcinoma in Trinidad was investigated. This study was a follow-up to an investigation of HPV genotypes in 310 nonsymptomatic women in Trinidad. The latter study showed that cervical HPV prevalence and heterogeneity of genotypes were high in the study population; notably, the genotypes targeted by the available HPV prophylactic vaccines were not the most common types. RESULTS The current study of 85 cases of invasive cervical squamous cell carcinomas demonstrated that the previously observed heterogeneity in HPV genotype distribution is lost in cases of invasive cervical cancer, with the vaccine-targeted HPV types HPV 16 and HPV 18 becoming the most prevalent. CONCLUSIONS HPV 16 and HPV 18 were the primary HPV genotypes associated with cases of invasive squamous cell carcinoma in the current Trinidad study. This strong association leads us to conclude that the HPV vaccines targeting HPV 16 and HPV 18 may contribute to reducing the cervical cancer burden in Trinidad.

Abstract
OBJECTIVES To assess the relationship of homocysteine, hs-CRP, with known cardiovascular risk factors of the metabolic syndrome. METHOD Cross sectional study comprised 182 diabetic outpatients (70 males and 112 females), attending endocrinology clinics in Trinidad. RESULTS Both male and females showed significant linear relationships between high sensitive C-reactive protein (hs-CRP), blood pressure and diabetes (r = -0.2 < R or R > 0.2). In females hs-CRP showed significant linear relationship with HDL, triglyceride, blood pressure and diabetes mellitus (p < 0.0001). The inverse relationship of hs-CRP with HDL implies the strong association of hs-CRP with metabolic syndrome. The multivariate logistic regression analysis showed significant relation of hs-CRP, metabolic syndrome and diabetes mellitus. There was no significant relationship of tHCY to any of the features studied. CONCLUSION Serum C-reactive protein is significantly related to features of the metabolic syndrome. Total plasma homocysteine, appears to be independent of both hs-CRP and features of the metabolic syndrome.

Abstract
OBJECTIVE To determine the relationship of biochemical parameters, BMI and blood pressure with age, gender and ethnicity of Trinidadian type 2-diabetic subjects. METHODS A retrospective case control study comprised of 1794 patient (740 males and 1054 females). RESULTS The correlation was found for lipid profile with age and gender in diabetic subjects. There was a positive significant correlation in LDL-C values for all age groups. Serum creatinine concentrations significantly varied amongst ethnicity (p = 0.02). Of the known ethnicities, East Indians had the highest mean creatinine value (1.00 ± 0.47 mg/dl). The univariate general linear model showed that lipid profile had many associations with gender and ethnicity in type 2 diabetic subjects. LDL-C had significant differences between gender (p = 0.04) and diabetes (p = 0.01). CONCLUSIONS Varied lipid profile with elevated systolic blood pressure and BMI are associated in type 2 diabetic patients with respect to age, gender and ethnicity.

Abstract
BACKGROUND In Trinidad and Tobago, the law on the mandatory use of seat belts was passed in 1995, but this law is hardly enforced. The objective of this study was to determine the frequency and predictors of seat belt use by motor vehicle drivers in the country. FINDINGS A cross-sectional study of 959 motor vehicle drivers using a self-administered questionnaire. Data analysis included Pearson Chi square test and multinomial logistic regression analysis in order to determine the possible predictors of seat belt use by the drivers in Trinidad and Tobago. A majority of the drivers sometimes (51.8%) or always (31.6%) use a seat belt. About 16.7%, 29% and 54.2% of the drivers perceived that the other drivers use their seat belts more frequently, with the same frequency and less frequently respectively compared to themselves. The main reason for not using seat belt by the drivers was given as frequent stops (40.7%) and the main motivation to use seat belt by the drivers was given as stiffer penalties for non-compliance with the seat belt law (44.5%). The predictors of seat belt use were male driver, no formal or lower level of education, driving for less than 10 years, and the perception that the other drivers use seat belts with the same or higher frequency compared to the respondents. CONCLUSION Only a small proportion of the drivers in Trinidad and Tobago always use a seat belt when driving. There is the need to enforce the seat belt legislation in the country.

Abstract
AIMS To determine the relationship between plasma adiponectin levels and obesity, inflammation, blood lipids and insulin resistance in type 2 diabetics (T2DM) and non-diabetics in a patient population in Trinidad. METHODS A cohort study of a total of 126 type 2 diabetic (42 males and 84 females) and 140 (43 males and 97 females) non-diabetic public clinic attendees were assessed between December 2008 and July 2009. Along with clinical history and anthropometry, adiponectin, TNF-α, IL-6, CRP, lipid profile, glucose, and insulin were measured in fasting blood samples and insulin resistance (HOMA-IR) was calculated. RESULTS Diabetics had higher (p<0.05) glucose, insulin, HOMA-IR, triglycerides (TG), VLDL and systolic blood pressure than non-diabetics, but lower (p<0.05) HDL and adiponectin levels. Adiponectin levels were lower (p<0.05) in obese than in non-obese individuals regardless of diabetic status. There were significant gender differences in HDL, LDL and TG. Among non-obese persons, adiponectin correlated negatively with triglycerides (r=-0.280; adiponectin), IL-6 (r=-0.216; p<0.005), HOMA-IR (r=-0.373; p=000) and positively correlated with HDL (r=0.355; p=0.000). Diabetic status (p=0.025), TNF-α (p=0.048) and BMI (p=0.027) were identified as useful predictors of adiponectin by multiple linear regression methods. In addition binary logistic regression analysis found glucose (p=0.001) and adiponectin (p=0.047) to be useful indicators of type 2 diabetes. CONCLUSIONS Adiponectin decreases with increasing adiposity and insulin resistance. Adiponectin and TNF-α appear to be related to differences in the insulin mediated glucose turnover.

Abstract
OBJECTIVE To determine whether elevated levels of troponin T are associated with altered lipid profile. METHODS Data were collected from 205 patients each of whom presented elevated troponin T levels. RESULTS 195 patients presented with suspected myocardial infarction, 10 patients did not. Of which 68 had medium, 107 high and 20 presented with very high troponin T levels. The proportions were significantly different (p = 0.000215). Regression analysis showed that troponin T level was a useful quadratic predictor of total cholesterol (p = 0.000), triglycerides (p = 0.003), and low density cholesterol (p = 0.000); and a useful linear predictor of TC/HC ratio (p = 0.001). CONCLUSIONS The occurrence of myocardial infarction is associated with elevated troponin T levels; troponin T is positively correlated with total cholesterol, triglycerides, LDL and TC/HC ratio and negatively correlated with HDL. TC/HC ratio was not found to be a useful predictor of the likelihood of MI.

Abstract
This study was conducted to guide the prioritisation of efforts to manage Cryptosporidum contamination of drinking water supplies in Trinidad, W.I. The main objective was to investigate the relative importance of three main types of sources of Cryptosporidium oocysts: urban, agriculture and wildlife. Weekly surface water samples were collected from 19 sites distributed among three watersheds, and examined for the presence of oocysts. A stratified random sampling design was used with each watershed representing one of the three main sources of oocysts listed above. Results showed a significant association between watershed and the occurrence of positive samples (chi(2)=16.523, d.f. =2, p = 0.000), indicating that land use influenced the presence of oocysts. Urban and forested lands were the two most important sources of oocysts. There was no apparent association between agriculture and the presence of oocysts, and there was no significant difference between the percentage of positive samples at sites below agricultural facilities and sites not associated with agriculture within a single watershed (chi(2)=2.45, d.f. =1, p = 0.117). We conclude that urban and wildlife are the main types of sources of Cryptosporidium contamination of surface water, whereas the contribution of agriculture is minor.

Abstract
OBJECTIVE To describe mortality trends and potential years of life lost (PYLL) due to leading causes of death in 21 Caribbean countries during 1985, 1990, 1995 and 2000. METHODS Mortality data for 1985, 1990, 1995 and 2000 were analyzed to identify regional mortality trends using crude, age-specific and age-adjusted death rates and potential years of life lost. The variables used were age, gender and underlying cause of death. RESULTS During 1985-2000, there was an overall 5% decrease in age-adjusted mortality rates and male mortality exceeded female mortality. Heart disease was the leading cause of death, with cancers, cerebrovascular diseases, diabetes mellitus and hypertensive disease also among the top five causes in most years. Prostate cancer and cancer of the uterus and breast were the leading causes of death due to cancers. HIV disease (AIDS) featured in the ten leading causes of death for the first time in 1995 and was the 5th leading cause in 2000. CONCLUSION During the period 1985-2000, countries experienced an increase in mortality due to non-communicable diseases, AIDS and assaults (homicides); the latter two causes were most common among the 15-44 year age group. In 2000, AIDS, heart disease and assault (homicide) were the largest contributors to PYLL.

Abstract
OBJECTIVE To determine the level of understanding of the issues of climate change (CC)/variability (CV) and public health by populations of St Kitts and Nevis (SKN) and Trinidad and Tobago (T&T) and to find whether respondents would be willing to incorporate these values into strategies for dengue fever (DF) prevention. DESIGN AND METHODS Using a cluster sampling system, representative samples of the communities of SKN (227) and T&T (650) were surveyed for responses to a questionnaire document with questions on the impact of climate variability on health, the physical environment, respondents' willingness to utilize climate issues to predict and adapt to climate variability for DF prevention. Data were analyzed by Epi Info. RESULTS Sixty-two per cent SKN and 55% T&T of respondents showed some understanding of the concept of climate change (CC) and distinguished this from climate variability (CV). With regard to causes of CC, 48% SKN and 50% T&T attributed CC to all of green houses gases, holes in the ozone layer burning of vegetation and vehicular exhaust gases. However some 39.3% SKN and 31% (T&T) did not answer this question. In response to ranking issues of life affected by CC/CV in both countries, respondents ranked them: health > water resources > agriculture > biodiversity > coastal degradation. The major health issues identified for SKN and T&T respondents were: food-borne diseases > water-borne diseases > heat stresses; vector-borne diseases were only ranked 4th and 5th for SKN and T&T respondents respectively. There was in both countries a significant proportion of respondents (p < 0.001) who reported wet season-related increase of DF cases as a CC/CV link. Respondents identified use of environmental sanitation (ES) at appropriate times as a method of choice of using CC/CV to prevent DF outbreaks. More than 82% in both countries saw the use of the CC/CV information for DF prevention by prediction and control as strategic but only 50-51% were inclined to become personally involved. Currently, only 50% SKN and 45% T&T respondents claimed current involvement in DF vector surveillance and control in the last two days. CONCLUSION Despite the fact that knowledge and attitudes did not always coincide with practices of using ES for DF prevention, in both countries, even with CC/CV tools of prediction being available, it seems that respondents could be persuaded to use such strategies. There is a need for demonstration of the efficacy of CC/CV information and promotion of its usefulness for community involvement in DF and possibly other disease prevention.

Abstract
When the currently used larval surveillance system (visual inspection) for the dengue vector Aedes aegypti was compared with the surveillance for the presence of eggs by ovitrapping in Port of Spain, Trinidad, it was found that the latter (39.1%) was significantly more sensitive than the visual inspection system (10.1%). At the same time, the presence of the nuisance mosquito Culex quinquefasciatus was detected in 38.4% of the households. Both Ae. aegypti and Cx. quinquefasciatus showed preference for ovipositional attractants in ovitraps: hay infusion > yeast suspension > plain tap water. Although all the socioeconomic and geographic areas produced both mosquito species in 1996, upper middle class (UMC) areas (8.6-43.4%) produced more Ae. aegypti than did lower middle class (LMC) areas (7.8-38.8%), which produced more than working class (WC) areas (3.9-29.9%). For Cx. quinquefasciatus, the order of production was reversed with WC areas (50.1%) > LMC areas (30.0%) > UMC areas (26.0%). Change in vector surveillance strategies incorporating some ovitrapping and stratified sampling are recommended for Caribbean countries.

Abstract
A hybrid problem based learning (PBL) and traditional medical programme was started at the Trinidad campus of the University of the West Indies in 1989. Analyses were carried out to determine the extent to which the entrance qualifications of the students were related to their performances at the examinations in the Phase I (preclinical and paraclinical) and Phase II (clinical) programmes. Students who were admitted on the basis of their results in the secondary school General Certificate of Examination (GCE), 'A' level scored higher at the Phase I, but not at the Phase II, level than those who already had university education. Among the 'A' level students, there was positive correlation between the total 'A' level scores and the examination marks in the medical programme, particularly at the Phase I level. Furthermore, multiple regression analyses indicated that the grades in 'A' level Chemistry and, to a lesser extent in Biology, had the most influence on performances at the Phase I examinations, with much less influence on performances at the Phase II examinations. These results suggest that good grades at 'A' level examinations are significant factors, but not the only important ones, that favour high achievement in the initial stages of this type of PBL/traditional medical programme.
