RESUMO
PURPOSE: The 2016 EQ-5D-3L value set for Trinidad and Tobago (T&T) allows for the calculation of EQ-5D-5L values via the crosswalk algorithm. The 2016 value set was based on methods predating the EQ-VT protocol, now considered the gold standard for developing EQ-5D value sets. Furthermore, direct elicitation of EQ-5D-5L is preferred over crosswalked values. This study aimed to produce an EQ-5D-5L value set for T&T. METHODS: A representative sample (age, sex, geography) of adults each completed 10 composite Time Trade-Off (cTTO) tasks and 12 Discrete Choice Experiment (DCE) tasks in face-to-face interviews. The cTTO data were analyzed using a Tobit model that corrects for heteroskedasticity. DCE data were analyzed using a mixed logit model. The cTTO and DCE data were combined in hybrid models. RESULTS: One thousand and seventy-nine adults completed the valuation interviews. Among the modelling approaches that were explored, the hybrid heteroskedastic Tobit model produced all internally consistent, statistically significant coefficients, and performed best in terms of out-of-sample predictivity for single states. Compared to the existing EQ-5D-5L crosswalk set, the new value set had a higher number of negative values (236 or 7.6% versus 21 or 0.7%). The mean absolute difference was 0.157 and the correlation coefficient between the two sets was 0.879. CONCLUSION: This study provides a value set for the EQ-5D-5L for T&T using the EQ-VT protocol. We recommend this value set for QALY computations relating to T&T.

BACKGROUND: In Trinidad and Tobago, non-communicable diseases (NCDs) are the leading cause of death. Unhealthy diet is one modifiable NCD risk factor, which contributes to the NCD burden. The consumption of sugar-sweetened beverages (SSBs) has been associated with an increased risk of NCDs. AIM: The aim of this paper is to estimate the burden of disease and economic costs associated with the consumption of SSBs in Trinidad and Tobago as evidence to support the implementation of health and fiscal policies on SSB consumption. METHODS: The results of this study were obtained through the use of a mathematical model which used a comparative risk assessment approach to estimate the health and economic burden associated with SSB intake, by sex and age. RESULTS: Estimates for one year showed that SSB consumption was associated with approximately 15,000 cases of overweight and obesity in adults and 11,700 cases in children, 28% of all the cases of diabetes and overall, an estimated 387 deaths and 9000 years of healthy life were lost due to premature death and disability. Approximately US$23.1 million was spent in the public healthcare system to treat diseases associated with consumption of sugary beverages. CONCLUSIONS: The consumption of SSBs is associated with increases in diseases, deaths and rising healthcare costs in Trinidad and Tobago. It is hoped that the results of this study will provide an added rationale and impetus for the implementation of policies to reduce the consumption of SSBs.
RESUMO
This article describes the introduction of the Pan American Health Organization's HEARTS in the Americas program in Trinidad and Tobago and the successful experiences and challenges encountered in introducing and scaling it up as a strategy for strengthening the health system's response to cardiovascular diseases. Evidence about implementation of the HEARTS program in the World Health Organization's Region of the Americas was reviewed to identify the progress made, barriers, success factors and lessons learned. In 2019, the Ministry of Health commenced implementation of the program in 5 (4.9%) of the 102 primary health care centers, and by the end of 2021, it had been scaled up to 46 (45.0%) centers. The HEARTS program ensures that patients' cardiovascular health is managed in a comprehensive way through providing counseling about a healthy lifestyle, using evidence-based treatment protocols, ensuring access to essential medicines and technologies, and using a risk-based team approach, a monitoring and evaluation system and also a team-based approach to care delivery. The barriers encountered during implementation included the fragmentation of the existing health care system, the paternalistic role assumed by health care professionals, the resistance of some health care workers to change and a lack of team-based approaches to providing care. Successful implementation of the program was enabled through ensuring high-level political commitment, establishing the national HEARTS Oversight Committee, ensuring stakeholder involvement throughout all phases and implementing standardized approaches to care. When implemented in the context of existing primary health care settings, the HEARTS program provides an exceptionally well integrated and comprehensive model of care that embodies the principles of universal health care while ensuring the health of both populations and individuals. Thus, it enables and promotes a strengthened primary health care system and services that are responsive and resilient.
En este artículo se describe la introducción del programa HEARTS en las Américas de la Organización Panamericana de la Salud en Trinidad y Tabago y las experiencias satisfactorias y los desafíos encontrados con su ejecución y ampliación como estrategia para fortalecer la respuesta del sistema de salud a las enfermedades cardiovasculares. Se reunieron datos sobre la ejecución del programa HEARTS en la Región de las Américas de la Organización Mundial de la Salud con el fin de determinar cuáles han sido los avances, los obstáculos, los factores de éxito y las enseñanzas extraídas. En el año 2019, el Ministerio de Salud inició la ejecución del programa en cinco (4,9%) de los 102 centros de atención primaria de salud, y para fines del 2021, se había ampliado a 46 (45,0%). El programa HEARTS garantiza el manejo integral de la salud cardiovascular de los pacientes mediante la prestación de asesoramiento sobre hábitos saludables, la aplicación de protocolos de tratamiento basados en la evidencia, la garantía de acceso a medicamentos y tecnologías esenciales, así como el uso de un enfoque de trabajo en equipo basado en el riesgo, un sistema de monitoreo y evaluación, y un enfoque basado en el equipo para abordar la prestación de la atención. Entre los obstáculos para su ejecución se encontraron la fragmentación del sistema de atención médica, el papel paternalista asumido por los profesionales de la salud, la resistencia al cambio de algunos trabajadores de salud y la falta de enfoques de trabajo en equipo para la prestación de la atención. La ejecución satisfactoria del programa fue posible gracias a un compromiso político de alto nivel, la creación de un comité nacional de supervisión de HEARTS, la participación de las partes interesadas en todas las fases del programa y la aplicación de enfoques estandarizados para la atención. En su ejecución en el contexto de los entornos de atención primaria de salud existentes, el programa HEARTS proporciona un modelo de atención excepcionalmente bien integrado y exhaustivo que encarna los principios de acceso universal a la atención de salud al tiempo que garantiza la salud individual y poblacional. De este modo, este modelo fomenta un sistema de atención primaria de salud fortalecido y unos servicios receptivos y resilientes.

Analisaram-se evidências sobre a implementação do programa HEARTS na Região das Américas da Organização Mundial da Saúde para identificar os avanços obtidos, os obstáculos, os fatores de sucesso e as lições aprendidas. Em 2019, o Ministério da Saúde iniciou a implementação do programa em 5 (4,9%) dos 102 centros de atenção primária à saúde; no final de 2021, o programa havia sido ampliado para 46 (45,0%) centros. O programa HEARTS assegura que a saúde cardiovascular dos pacientes seja manejada de uma forma abrangente por meio de aconselhamento sobre estilo de vida saudável, uso de protocolos de tratamento baseados em evidências, garantia de acesso a medicamentos e tecnologias essenciais e utilização de uma estratégia de equipe baseada no risco, de um sistema de monitoramento e avaliação e de uma abordagem de atendimento baseado em equipe. Os obstáculos encontrados durante a implementação incluíam a fragmentação do sistema de saúde existente, o papel paternalista assumido pelos profissionais de saúde, a resistência de alguns profissionais de saúde a mudanças e a falta de abordagens baseadas em equipe na prestação do atendimento. Para permitir que a implementação do programa fosse bem-sucedida, obteve-se compromisso político de alto nível, criou-se o Comitê de Supervisão do HEARTS nacional, assegurou-se o envolvimento de interessados diretos em todas as fases e implementaram-se abordagens padronizadas de atendimento. Quando implementado no contexto dos ambientes existentes de atenção primária à saúde, o programa HEARTS oferece um modelo de atenção excepcionalmente bem integrado e abrangente que incorpora os princípios de atenção universal à saúde, ao mesmo tempo em que garante a saúde das populações e dos indivíduos. Dessa forma, viabiliza e promove um sistema de atenção primária à saúde fortalecido e serviços responsivos e resilientes.
RESUMO
BACKGROUND: Approximately one-third of adults in Trinidad and Tobago have high blood pressure (hypertension). Excessive consumption of sodium (Na+) is a known risk factor for hypertension. AIM: We investigated Na+ and potassium (K+) intakes and their correlates in a multi-ethnic Caribbean population. METHOD: Volunteers completed a self-administered questionnaire comprising socio-demographic items, physical activity (PA) and a semiquantitative food frequency questionnaire. Foods eaten were classified by level of processing using the NOVA classification system and analysed for Na+ and K+ levels using appropriate dietary analysis software. The study was approved by the University of the West Indies at Saint Augustine Ethics Committee. RESULTS: 11,783 adults participated in the study. Approximately 83.2% of total calories, 79% of Na+ and 40% of K+ was derived from the consumption of highly processed foods. Median daily Na+ and K+ intakes were 2759 mg and 2853 mg, respectively. Na+ intakes showed significant nonlinear increases with age (p < 0.001) and body mass index (BMI) (p < 0.001), and non-linear decreases with educational attainment (p < 0.001). K+ intakes showed significant nonlinear decreases with age (p < 0.001) and BMI (p < 0.001), and linear increases with educational attainment (p < 0.001). Males had higher intakes of Na+ and K+ than females. Na+: K+ was lower among persons participating in moderate to high intensity PA ≥ 150 minutes/week compared to those participating in such activities < 150 minutes/week. CONCLUSION: Socio-demographic factors were significantly correlated with Na+ and K+ intakes among participants and must be considered in strategies aimed at achieving healthy intakes of these nutrients.

Vaginal Candidiasis and associated epidemiological risk factors prevalent among a cross section of pregnant women attending tertiary hospital in Trinidad and Tobago was evaluated. Standardized questionnaire was used to survey 492 pregnant women over a period of 10 months in 2019. Vaginal swab was collected and processed using standard microbiological laboratory methods for phenotypic identification. Data were analyzed using SPSS to identify potential risk factors. Chi-squared (ê2) test and logistic regression tests examined associations and odds ratios with corresponding 95% confidence intervals. Prevalence of vulvovaginal candidiasis was 44.9% with Candida albicans as predominant species identified (62%, N=492). Vaginal candidiasis was statistically significant for several risk factors, including second trimester (p = 0.03), age group 26 - 34 years (p=003), history of masturbation especially during the last 48hours prior to the swabbing (p=0.05), and wearing of pants as opposed to skirt clothes (p=0.04). In conclusion, several epidemiological risk factors are associated vaginal candidiasis among cross section of pregnant women in the country. Patient education, microbiological investigations and appropriate treatment will improve antenatal healthcare delivery in the country.

PURPOSE: The aim of this study is to determine the demographic, pathological, and treatment-related factors that predict recurrence and survival in a Trinidadian cohort of breast cancer patients. METHODS: The inclusion criteria for this study were female, over 18 years, and with a primary breast cancer diagnosis confirmed by a biopsy report occurring between 2010 and 2015 at Sangre Grande Hospital, Trinidad. Univariate associations with 5-year recurrence-free survival and 5-year overall survival were calculated using the Kaplan-Meier method for categorical variables and Cox Proportional Hazards for continuous variables. A multivariate model for prediction of recurrence and survival was determined using Cox regression. RESULTS: For the period 2010-2015, 202 records were abstracted. Five-year overall survival and recurrence-free survival rates were found to be 74.3% and 56.4%, respectively. Median times from first suspicious finding to date of biopsy report, date of surgery, and date of chemotherapy were 63 days, 125 days, and 189 days, respectively. In the univariate analysis, age (p = 0.038), stage (p < 0.001), recurrence (p = 0.035), surgery (p = 0.016), ER (p < 0.001) status, PR status (p < 0.001), and subtype (p < 0.001) were significantly associated with survival. Additionally, stage (p = 0.004), N score (p = 0.002), ER (p = 0.028) status, PR (p = 0.018) status, and subtype (p = 0.025) were significantly associated with recurrence. In the Cox multivariate model, Stage 4 was a significant predictor of survival (HR 6.77, 95% CI [0.09-2.49], p = 0.047) and N3 score was a significant predictor of recurrence (HR 4.47, 95% CI [1.29-15.54], p = 0.018). CONCLUSION: This study reports a 5-year breast cancer survival rate of 74.3%, and a recurrence-free survival rate of 56.4% in Trinidad for the period 2010-2015.

Cervical cancer is a major public health problem in Latin America and the Caribbean and the human papillomavirus (HPV) vaccine may prevent thousands of cases of cervical cancer. The current study explored barriers and facilitators that affected the acceptance of the HPV vaccine by mothers of adolescents. This paper explores the qualitative findings from a larger mixed-methods study. Six focus groups were conducted (N = 33) throughout Trinidad and Tobago with mothers of adolescent girls. Three major themes emerged: a) cervical cancer and vaccine knowledge, b) barriers to uptake, and c) rephrasing the vaccine strategy. Data indicated that no widespread strategies to educate the population about the vaccine had occurred. Barriers to uptake of the vaccine were related to a lack of information on the efficacy and safety of HPV vaccines. Parents were unaware that the HPV caused cervical cancer. It is recommended that physicians and other health professionals be used to deliver targeted messages to parents and adolescents to improve uptake of the vaccine.

BACKGROUND: This study aimed to screen cardiovascular patients for depressive symptoms at a tertiary centre in Trinidad and Tobago; and to determine any significant associations amongst patients' demographics, comorbidities, and cardiovascular medications with depressive symptoms. METHODS: In this observational, cross-sectional study, patients (n = 1203) were randomly selected from the cardiology outpatient clinics at the Eric Williams Medical Sciences Complex. After meeting selection criteria, informed consent was obtained, and patients were administered a case report form, which included the Patient Health Questionnaire-9 (PHQ-9). Descriptive analyses included frequency, percentage and summary statistics. Inferential analyses included 95% confidence intervals (CIs), independent sample t-test, Fisher's exact test, Chi-square test, and multivariate logistic regression. RESULTS: The study had a 96% respondent rate, whereby the average age was 62 years old. Slightly less than half were male, and 52.5% were female. Over 90 % of the sample had cardiovascular disease (CVD). One-quarter of the sample had a PHQ-9 score of ≥10, with almost one-fifth having no depressive symptoms. Females, lower levels of education and income were all found to be statistically significant at risk for depressive symptoms (all p-values < 0.001). Comorbidities associated with depressive symptoms included hypertension, prior cerebrovascular events, chronic kidney disease, and chronic obstructive pulmonary disease with odds ratios (ORs) and 95% confidence intervals (CIs) of OR 1.988 (CI 1.414-2.797), OR 1.847 (CI 1.251-2.728), OR 1.872 (CI 1.207-2.902) and OR 1.703 (CI 1.009-2.876) respectively. Only the cardiovascular medication of ticagrelor was found to be significantly associated with depressive symptoms (p-value < 0.001). CONCLUSIONS: Twenty-five percent of screened cardiovascular patients displayed significant depressive symptoms with a PHQ-9 ≥ 10. This study also highlights the importance of implementing a multidisciplinary approach to managing cardiovascular disease and screening for depressive symptoms in this subpopulation. Further studies are required to validate these findings. TRIAL REGISTRATION: ClinicalTrials.gov number, NCT03863262 . This trial was retrospectively registered on 20th February 2019.

BACKGROUND AND AIM: Access to specialized cardiac surgery is a problem in emerging countries. Here, we reflect on the approach we used to establish a cardiac surgery unit in Trinidad and Tobago. METHODS: The program started in 1993 with monthly visits by a team from Bristol Heart Institute. A group of local doctors, nurses, and perfusionists were identified for training, and a senior nurse moved to the island to start a teaching program. The visiting support was gradually reduced, and the local team gained independence in managing the service in 2006. RESULTS: The initial low volume surgery increased to around 380 cases a year with the implementation of comprehensive service in 2006. Most patients required coronary artery bypass graft (CABG). In-hospital mortality declined from 5% in the nascent years to below 2% thereafter. In the last 5 years (2015-2019), 1764 patients underwent surgery (mean age 59.6 ± 10.8 years, 66% male). The majority were East-Indian-Caribbean (79.1%) or Afro-Caribbean (16.7%), half had diabetes, and two-thirds hypertension (EuroScore II 1.8 ± 1.9). The majority (1363 patients) underwent CABG (99.5% off-pump; conversion to on-pump 1.5%). The mean number of grafts was 2.5 ± 0.7 with 98.5% and 23.1% receiving one and two or more arterial grafts, respectively. In-hospital mortality was 1.1%, re-exploration for bleeding 2%, stroke 0.1%, mediastinitis 0.2%. The length of the postoperative hospital stay was 5.8 ± 2 days. CONCLUSION: Frequent outside visits complemented by training in an overseas center, and transfer of knowledge proved to be an effective strategy to develop a cardiac surgery unit in an emerging country with results comparable to accepted international standards.

Gender variations in health literacy have implications for engagement in preventive behaviours and the uptake of health services, especially in areas such as the Caribbean where there are marked disparities in life expectancy and health service utilization. A self-reported questionnaire was used to examine men's concepts of health, their help-seeking behaviours and their functional and interactive health literacy. Two hundred and forty-eight men across the life course participated at three sites in Trinidad. Data were analysed using descriptive statistics, with free-text responses analysed thematically. Men were concerned about, and accepted responsibility for their own health but social norms concerning sickness and masculinity were barriers to accessing health services. Almost one-third (31.5%) sought advice from a healthcare service when they were last sick because they were prompted to do so by their wife/partner or family. Levels of functional and interactive health literacy were not high among older men, who were reliant on healthcare professionals to communicate health messages. There was an age divide in e-health literacy. There is little published evidence on men's health literacy, particularly from Caribbean countries such as Trinidad and Tobago. This study highlights the importance of the design and implementation of specific policies focusing on men's health. A major challenge is to engage with men who do not access health services.

A newly modified QuEChERS method was developed, validated, and tested in-house for the multiclass, multiresidue determination of organophosphate (OPP) and organochlorine pesticide (OCP) residues in fruits and vegetables. The method incorporated a solvent extraction with acetonitrile followed by partitioning with magnesium sulphate (MgSO4) and sodium chloride (NaCl). The final step involved a dispersive solid phase extraction (d-SPE) clean-up prior to gas chromatography with electron capture detection (GC-ECD) analysis. Apples and lettuce were the selected matrices for fruits and vegetables, respectively in the method development stages. Various combinations of sorbents were tested in the clean-up step. Florisil and MgSO4 (FM) d-SPE proved to be the best combination for the clean-up step for both OCPs and OPPs in both the fruit and vegetable matrices. Recovery values fell within the acceptable range of 70 to 120% (RSD ≤ 20%). The new method is unique as it employs the standard addition calibration technique for the quantification of OCP and OPP residues. Limit of detection, limit of quantification, linearity, recovery analysis, and repeatability were validation parameters used to evaluate the accuracy, precision, and ruggedness of the method. The newly modified QuEChERS method provides a cheaper alternative for the analysis of pesticide residues in fruits and vegetables as samples can be analysed at a fraction of the cost of the original QuEChERS method. The efficacy of the method was tested on several fruits and vegetables from the Central Division of Trinidad and Tobago. OCP and OPP residues were found in 61% of the samples, most of which were above the maximum residue limits.

INTRODUCTION: Breast cancer (BC) is the leading cause of cancer death in Caribbean women. Across the Caribbean islands, the prevalence of hereditary breast cancer among unselected breast cancer patients ranges from 5 to 25%. Moreover, the prevalence of BC among younger women and the high mortality in the Caribbean region are notable. This BC burden presents an opportunity for cancer prevention and control that begins with genetic testing among high-risk women. Measured response to positive genetic test results includes the number of preventive procedures and cascade testing in family members. We previously reported data on an active approach to promote cascade testing in the Bahamas and report on preventive procedures showing moderate uptake. Here, we describe a clinically structured and community-partnered approach to the dissemination and follow-up of genetic test results including family counseling for the promotion of risk mitigation strategies and cascade testing in our Trinidadian cohort of patients tested positive for BC predisposition genes. METHODS: As a part of our initial study of BC genetic testing in Trinidad and Tobago, all participants received pre-test counseling including three-generation pedigree and genetic testing for BRCA1/2, PALB2, and RAD51C. The study was approved by the University of Miami IRB and the Ethics Committee of the Ministry of Health, Trinidad and Tobago. We prospectively evaluated a clinically structured approach to genetic counseling and follow-up of BC mutation carriers in Trinidad and Tobago in 2015. The intervention consisted of (1) engaging twenty-nine BC patients with a deleterious gene mutation (probands), and (2) invitation of their at-risk relatives to attend to a family counseling session. The session included information on the meaning of their results, risk of inheritance, risk of cancer, risk-reduction options, offering of cascade testing to family members, and follow-up of proband decision-making over two years. RESULTS: Twenty-four of twenty-nine mutation carriers (82.8%) consented to enroll in the study. At initial pedigree review, we identified 125 at-risk relatives (ARR). Seventy-seven ARR (62%) attended the family counseling sessions; of these, 76 ARR (99%) consented to be tested for their family gene mutation. Genetic sequencing revealed that of the 76 tested, 35 (46%) ARR were carriers of their family mutation. The ARR received their results and were urged to take preventative measures at post-test counseling. At 2-year follow-up, 6 of 21 probands with intact breasts elected to pursue preventive mastectomy (28.5%) and 4 of 20 women with intact ovaries underwent RRSO (20%). CONCLUSIONS: In Trinidad and Tobago, a clinically structured and partnered approach to our testing program led to a significant rate of proband response by completing the intervention counseling session, executing risk-reducing procedures as well as informing and motivating at-risk relatives, thereby demonstrating the utility and efficacy of this BC control program.

OBJECTIVE: The aim of this study was to explore Trinidad and Tobago (TT) men's prediagnosis experiences of prostate cancer (PCa). This study is part of a wider project that examined men and their partners' experiences of routes to diagnosis for PCa in TT. METHODS: Men (n = 51) were voluntarily recruited to semi-structured interviews from four centres. Data were analysed following principles of grounded theory. RESULTS: Major barriers to medical help seeking were highlighted as lack of knowledge and awareness of the prostate gland and symptoms of PCa, the digital rectal exam (DRE), prostate-specific antigen (PSA), cultural and religious beliefs, and hegemonic masculinity norms and nonreporting of bodily changes to GPs. Fear of DRE, distrust in providers, and misinterpretation of bodily changes as related to ageing and diabetes mellitus also contributed to delays towards seeking medical help. Men's interactions with pharmacists and traditional healers lengthened the time taken to consult with health care providers for prostate concerns. CONCLUSIONS: TT men's PCa prediagnosis experiences are important to unearth barriers and facilitators to care along routes to diagnosis for this disease. This can help target specific health promotion strategies to motivate men to seek medical care for symptoms in a timely manner.

PURPOSE: A situational analysis of breast cancer (BC) early detection services was carried out to investigate whether Trinidad and Tobago (T&T) has the framework for successful organized national screening. METHODS: An online survey was designed to assess the availability, accessibility, quality control and assurance (QC&A), and monitoring and evaluation (M&E) mechanisms for public and private BC early detection. A focus group with local radiologists (n = 3) was held to identify unaddressed challenges and make recommendations for improvement. RESULTS: Major public hospitals offer free detection services with wait times of 1-6 months for an appointment. Private institutions offer mammograms for TTD$240 (USD$37) at minimum with same day service. Both sectors report a lack of trained staff. Using 1.2 mammograms per 10,000 women ≥40 years as sufficient, the public sector's rate of 0.19 mammograms per 10,000 women ≥40 years for screening and diagnosis is inadequate. Program M&E mechanisms, QC&A guidelines for machinery use, delays in receipt of pathology reports, and unreliable drug access are further unaddressed challenges. CONCLUSION: T&T must first strengthen its human and physical resources, implement M&E and QC&A measures, strengthen cancer care, and address other impediments to BC early detection before investing in nationally organized BC screening.

PURPOSE: In Trinidad and Tobago (TT), prostate cancer (CaP) is the most commonly diagnosed malignancy and the leading cause of cancer deaths among men. TT currently has one of the highest CaP mortality rates in the world. METHODS: 6,064 incident and 3,704 mortality cases of CaP occurring in TT from January 1995 to 31 December 2009 reported to the Dr. Elizabeth Quamina Cancer population-based cancer registry for TT, were analyzed to examine CaP survival, incidence, and mortality rates and trends by ancestry and geography. RESULTS: The age-standardized CaP incidence and mortality rates (per 100,000) based on the 1960 world-standardized in 2009 were 64.2 and 47.1 per 100,000. The mortality rate in TT increased between 1995 (37.9 per 100,000) and 2009 (79.4 per 100,000), while the rate in the US decreased from 37.3 per 100,000 to 22.1 per 100,000 over the same period. Fewer African ancestry patients received treatment relative to those of Indian and mixed ancestry (45.7%, 60.3%, and 60.9%, respectively). CONCLUSIONS: Notwithstanding the limitations surrounding data quality, our findings highlight the increasing burden of CaP in TT and the need for improved surveillance and standard of care. Our findings highlight the need for optimized models to project cancer rates in developing countries like TT. This study also provides the rationale for targeted screening and optimized treatment for CaP to ameliorate the rates we report.

BACKGROUND: Cancer is the second leading cause of death in the Caribbean, including the islands of Trinidad and Tobago (TT). The population of TT consists of over 1.3 million people with diverse ancestral and sociocultural backgrounds, both of which may influence cancer incidence and mortality. The objective of this study was to examine incidence and mortality patterns and trends in TT. METHODS: Cancer surveillance data on 29,512 incident cancer cases reported to the Dr. Elizabeth Quamina Cancer Registry (population-based cancer registry of TT) between 1995 and 2009 were analyzed. Age-standardized rates, overall and by sex, ancestry, and geography, were reported. RESULTS: The highest incidence and mortality rates were observed for cancers related to reproductive organs in women, namely, breast, cervical, and uterine cancers, and prostate, lung and colorectal cancers among men. Average incidence rates were highest in areas covered by the Tobago Regional Health Authority (TRHA) (188 per 100,000), while average mortality rates were highest in areas covered by the North West Regional Health Authority (108 per 100,000). Nationals of African ancestry exhibited the highest rates of cancer incidence (243 per 100,000) and mortality (156 per 100,000) compared to their counterparts who were of East Indian (incidence, 125 per 100,000; mortality, 66 per 100,000) or mixed ancestry (incidence, 119 per 100,000; mortality, 66 per 100,000). CONCLUSIONS: Our findings highlight the need for national investment to improve the understanding of the epidemiology of cancer in Trinidad and Tobago, and to ultimately guide much needed cancer prevention and control initiatives in the near future.

Historical and cultural experiences have shaped the life experiences of cultural communities in Trinidad and Tobago. Using a cultural focus, the goal of this investigation was to examine ethnic variations both in the prevalence of common mental disorder (CMD) symptoms as well as in the associations between sociodemographic, psychosocial, physical health correlates and CMDs among mothers in Trinidad and Tobago. Participants included 1002 mothers (359 African-, 353 Indo- and 290 Mixed-Ethnic Trinidadian). Mean comparisons indicated similarities in the levels of depression, somatisation and anxiety across ethnic groups. The associations between physical ill health, experiences of pain and depression and between physical ill health and somatisation were stronger for Mixed-Ethnic Trinidadian than Indo-Trinidadian mothers. The relationship between early experiences of domestic violence and depression was stronger for Indo-Trinidadian than Mixed-Ethnic Trinidadian mothers. The associations between early experiences of domestic violence and depression and between experiences of pain and somatisation were stronger for African Trinidadian than Mixed-Ethnic Trinidadian mothers. Thus beyond the direct effects, mothers belonging to specific ethnic groups indicated greater or lesser vulnerabilities to CMDs depending on their exposure to specific correlates. Results have applicability for the development of culturally sensitive interventions for mothers experiencing CMDs.

AIMS: To determine the virulence and antimicrobial resistant genes in methicillin resistant Staphylococcus aureus isolates recovered from patients attending two rural health centers in Trinidad and Tobago. SETTINGS AND DESIGN: Cross-sectional observational analysis of patients from two local health centers located in communities in northern region of the country. MATERIALS AND METHODS: Nasal and wound swabs from 300 patients were analyzed using standard and molecular techniques. Multiplex polymerase chain reaction was used to detect 16S rRNA, mec A, Staphylococcal chromosomal cassette SCC mec types, pvl, alpha hemolysin (hla), and Toxic Shock Syndrome Toxin 1 (tst 1) genes. S. aureus ATCC 33591 and Staphylococcus epidermidis ATCC 12228 were used for quality control, respectively. RESULTS: Over a quarter (26.7%, 80/300) of the surveyed patient's samples grew bacterial isolates of which 45% (36/80) were S. aureus and 44.4% (16/36) were mecA-positive. Majority (62.5%, 10/16) possessed the pvl gene, whereas 25% (4/16) possessed the alpha hemolysin (hla) gene. None of the methicillin-resistant Staphylococcus aureus (MRSA) isolates possessed the tst 1 gene. Also, 18.8% (3/16) isolates possessed both virulence genes, pvl and hla. Although the SCCmec types IV and V were detected, but none of the SCCmec I, II, and III were harbored by the isolates. CONCLUSIONS: SCCmec type IV and the pvl genes were common among the MRSA isolates from the community. The hla gene was found infrequently, but none of the isolates possessed the tst 1 gene. Knowledge of this is important for robust surveillance of such cases from the community in the country.

PURPOSE: To examine the factors associated with gynecologic cancer mortality risks, to estimate the mortality-to-incidence rate ratios (MIR) in Trinidad and Tobago (TT), and to compare the MIRs to those of select countries. METHODS: Data on 3,915 incident gynecologic cancers reported to the National Cancer Registry of TT from 1 January 1995 to 31 December 2009 were analyzed using proportional hazards models to determine factors associated with mortality. MIRs for cervical, endometrial, and ovarian cancers were calculated using cancer registry data (TT), GLOBOCAN 2012 incidence data, and WHO Mortality Database 2012 data (WHO regions and select countries). RESULTS: Among the 3,915 incident gynecologic cancers diagnosed in TT during the study period, 1,795 (45.8%) were cervical, 1,259 (32.2%) were endometrial, and 861 (22.0%) were ovarian cancers. Older age, African ancestry, geographic residence, tumor stage, and treatment non-receipt were associated with increased gynecologic cancer mortality in TT. Compared to GLOBOCAN 2012 data, TT MIR estimates for cervical (0.49 vs. 0.53), endometrial (0.61 vs. 0.65), and ovarian cancers (0.32 vs. 0.48) were elevated. While the Caribbean region had intermediate gynecologic cancer MIRs, MIRs in TT were among the highest of the countries examined in the Caribbean region. CONCLUSIONS: Given its status as a high-income economy, the relatively high gynecologic cancer MIRs observed in TT are striking. These findings highlight the urgent need for improved cancer surveillance, screening, and treatment for these (and other) cancers in this Caribbean nation.

BACKGROUND: Identification of the prevalence and spread of ESBL-mediated antibiotic resistance is essential especially in the hospital setting. It is for this reason, more and more studies are highlighting the importance of complementing phenotypic ESBL-detection techniques with molecular techniques in order to understand the basis and extent of this form of resistance among clinically evolved bacterial populations, especially those belonging to the Enterobacteriaceae family. However, in Trinidad and Tobago and other Caribbean countries, very little is known regarding ESBL detection rates and/or the prevalence of genes conferring ESBL resistance. METHODOLOGY: Sixty-six Klebsiella pneumoniae isolates from clinical specimens phenotypically identified by the Microscan Walkaway-96 System as potential ESBL-producers were analysed in this study. Screening and confirmation of these isolates as ESBL producers was done by the Clinical and Laboratory Standards Institute (CLSI) approved methods. Polymerase chain reaction amplification of beta-lactamase genes bla TEM, bla SHV, bla CTX-M1, bla CTX-M2 and bla AmpC was performed to identify mechanisms of ß-lactam resistance. RESULTS: ESBL-producing K. pneumoniae was confirmed in 78.8% (41/52) from isolates collected from a variety of sources during the period, April-July 2015. bla SHV (84.8%) and bla CTX-M (46.9%) were the predominant ß-lactamase genes identified. A single K. pneumoniae isolate possessed a bla CTX-M group 2 beta-lactamase gene. RAPD analysis identified a number of epidemiologically related isolates. However, current isolates were unrelated to isolates from previous years. CONCLUSION: This study revealed that among K. pneumoniae isolates exhibiting extended spectrum ß-lactam resistance, there was a high prevalence of bla SHV and bla CTX-M genes. This result highlights the need for a reliable epidemiological apparatus that involves the molecular characterisation of ESBL resistance.
