RESUMEN
World Health Organization (WHO) / Pan American Health Organization (PAHO) encouraged the utilization of whole-of-society and whole-of-government strategic approaches to increase countries' resilience towards mitigating the impact of the COVID-19 pandemic. Strategies included the implementation of multi-sectoral, multi-partner and multi-stakeholder planning, coordination, consultation, and action. We reviewed the experiences of three Latin American and Caribbean countries, related to the implementation of collaborative strategies in tackling COVID-19, specifically the nature of the collaboration, the dynamics and the stakeholders involved.A systematic literature review identified relevant publications and content analysis was conducted to determine the collaborative strategies. Colombia, Costa Rica, and Trinidad and Tobago were selected as case studies since they were from different LAC subregions and because of the accessibility of relevant literature.In the three countries, the pandemic response was coordinated by a national executive committee, led by the Ministry of Health. Intersectoral collaboration was evident in each, with the key stakeholders being public sector agencies, the private/corporate sector, private/non-profit, academic institutions, and international agencies. It was used primarily to facilitate data-driven, evidenced-informed decision-making and guidelines; to expand clinical care capacity and strengthen the national medical response; and to provide support for the most vulnerable populations.While the institutionalization of intersectoral collaboration can be recommended for the health sector beyond the pandemic, research is needed to evaluate the impact of specific collaborative strategies as well as barriers and facilitators.

Trinidad and Tobago are islands in the Southern Caribbean with a unique mix of races within the population consisting of East Indian (EI) (37.6%), Afro-Caribbean (AC) (36.3%), mixed (24.2%), and Caucasian, Chinese, Lebanese, Syrian, Amerindian, and Spanish groups accounting for 1.9%. It makes it suitable for a comparison of breast carcinoma receptor expression within a fixed environment. This study included 257 women with an age range of 28 to 93 years (mean = 57.2, standard deviation = 15.0), peak age group of 51 to 60 consisting of 105 EI, 119 AC, and 33 mixed descent. Invasive ductal carcinoma accounted for 88%, invasive lobular 9.7%, and ductal carcinoma in situ 2.3%. The triple-negative rates were 24.8, 33.6, and 30.3% for EI, AC, and mixed races, respectively, with the Pearson's chi-square test revealing statistical significance for the AC versus EI ( p < 0.001); AC versus mixed ( p < 0.001); and EI versus mixed ( p = 0.014) groups. The overall estrogen (ER), progesterone (PR), and human epidermal growth receptor (HER) expression negative rates were 52, 64, and 79%, respectively. Chi-square test of the following combinations: ER +/PR +/HER + ; ER +/PR +/HER - ; ER -/PR -/HER + ; ER +/PR -/HER + ; ER +/PR -/HER - ; ER -/PR +/HER + ; ER -/PR +/HER- revealed no statistical differences ( p = 0.689).
RESUMEN
The Caribbean has long been an under-represented geographical region in the field of genomics research. Such under-representation may result in Caribbean people being underserved by precision medicine and other public health benefits of genomics. A collaboration among regional and international researchers aims to address this issue through the H3ECaribbean project (Human Heredity, Environment, and Health in the Caribbean), which builds on the lessons and success of H3Africa. The Caribbean project aims to target issues of social justice by encouraging the inclusion of diverse Caribbean communities in genomics research. This paper explores a framework for the ethical and socially acceptable conduct of genomics research in the Caribbean, taking account of the cultural peculiarities of the region. This is done in part by exploring research ethics issues identified in indigenous communities in North America, Small Island Developing States, and similar endeavours from the African continent. The framework provides guidance for interacting with local community leaders, as well as detailing steps for obtaining informed consent of all participants. Specifically, the authors outline the methods to ensure effective interaction and enforce full transparency with study participants to combat historical neglect when working with under-represented communities in the Caribbean.
RESUMEN
Objectives and importance of study: The importance of health policy and systems research (HPSR) has been acknowledged since 2004 and was recognised by the United Nations World Health Assembly in 2005. However, many factors influence its development. This paper aims to analyse the impact of politics and political determinants on HPSR funding in selected countries of Latin America and the Caribbean. METHODS: Using a standardised protocol, we performed an analysis of available data and financing structures for health research and HPSR, based on research in eight countries, including interviews with key stakeholders (n = 42). RESULTS: Dollar depreciation and gross national product growth in the region may play a role in how governments fund research. There have been shifts in the political spectrum in governments, which have affected research coordination and funding in positive and negative ways. HPSR funding in some countries was dependent on budget decisions and although some have improved funding, others have regressed by decreasing funding or have completely cancelled financing mechanisms. Caribbean countries rely mainly on institutional funding. HPSR is recognised as important but remains underfunded; stakeholders believed it should be used more in decision making. CONCLUSION: Although HPSR is recognised as valuable for decision making and policy development, it does not have the financial support required to flourish in Latin America and the Carribean. Data on health research financing were not easy to access. There was little or no evidence of published reports or papers about research financing, health research funding, and HPSR funding in particular in the studied countries. Because of the fragility of health systems highlighted by the coronavirus disease 2019 (COVID-19) pandemic, HPSR should be of great relevance and value to both policy makers and funders.

Trinidad and Tobago, a small island developing state, has been ranked as number one in a report published by the University of Oxford that assessed responses to COVID-19 based on four of the six WHO criteria for rolling back COVID-19 "lockdown" measures. The key mitigation and containment strategies implemented by the country were evidence-informed and demonstrated an "all-of-government" approach. The COVID-19 health system response of this country demonstrates that although developing countries face many health system challenges, political will, evidence-informed decision-making, respect for science, and timely, coordinated, collaborative actions can strengthen the resilience and response of the health system during a health emergency.

Cancer causes a fifth of deaths in the Caribbean region and its incidence is increasing. Incidence and mortality patterns of cancer in the Caribbean reflect globally widespread epidemiological transitions, and show cancer profiles that are unique to the region. Providing comprehensive and locally responsive cancer care is particularly challenging in the Caribbean because of the geographical spread of the islands, the frequently under-resourced health-care systems, and the absence of a cohesive approach to cancer control. In many Caribbean countries and territories, cancer surveillance systems are poorly developed, advanced disease presentations are commonplace, and access to cancer screening, diagnostics, and treatment is often suboptimal, with many patients with cancer seeking treatment abroad. Capacity building across the cancer-control continuum in the region is urgently needed and can be accomplished through collaborative efforts and increased investment in health care and cancer control.

BACKGROUND: Relationships between low forced vital capacity (FVC), and morbidity have previously been studied but there are no data available for the Caribbean population. This study assessed the association of low FVC with risk factors, health variables and socioeconomic status in a community-based study of the Trinidad and Tobago population. METHODS: A cross-sectional survey was conducted using the Burden of Obstructive Lung Disease (BOLD) study protocol. Participants aged 40 years and above were selected using a two-stage stratified cluster sampling. Generalized linear models were used to examine associations between FVC and risk factors. RESULTS: Among the 1104 participants studied a lower post-bronchodilator FVC was independently associated with a large waist circumference (- 172 ml; 95% CI, - 66 to - 278), Indo-Caribbean ethnicity (- 180 ml; 95% CI, - 90 to - 269) and being underweight (- 185 ml; 95% CI, - 40 to - 330). A higher FVC was associated with smoking cannabis (+ 155 ml; 95% CI, + 27 to + 282). Separate analyses to examine associations with health variables indicated that participants with diabetes (p = 0â041), history of breathlessness (p = 0â007), and wheeze in the past 12 months (p = 0â040) also exhibited lower post-bronchodilator FVC. CONCLUSION: These findings suggest that low FVC in this Caribbean population is associated with ethnicity, low body mass index (BMI), large waist circumference, chronic respiratory symptoms, and diabetes.

PURPOSE: With high mortality in breast, cervical, prostate, and colorectal cancers in Caribbean Community (CARICOM) countries, we examined cancer control initiatives including screening as well as the implementation of relevant international and regional mandates. METHODS: Secondary data were used to examine cancer control initiatives, which included the presence of national policies, programs, and screening services as well as the implementation of international and regional mandates. To identify the data, an on-line search was conducted using Google/Google Scholar. RESULTS: Data were available for 14 of the 15 full members of CARICOM. Although only six countries had distinct cancer control policies, strategies or action plans, all 14 had key elements of cancer control programs. Screening services were available in the 14 countries for cervical, in 12 countries for breast and in 11 for colorectal cancer. However, only four countries had screening policies. In addition, screening guidelines were available for cervical cancer in nine countries, in one country for breast and in none for colorectal cancer. Selected tobacco control policies were present in the 14 countries and immunization policies for human papillomavirus (HPV) in 13. Treatment services included chemotherapy in 10 countries and radiotherapy in six. Nine countries had palliative care services for patients with advanced disease. The countries were at different stages of implementation/compliance with international and regional mandates and frameworks. CONCLUSIONS: There is an urgent need to develop and implement comprehensive and customized cancer control policies addressing screening programs, treatment and palliative care.

DISCUSSION: Erectile dysfunction (ED) is common, and the observed rate was 53 per cent, in men over 40 years of age attending Trinidadian GP. There were statistically significant associations between the patient's age and ethnicity, and the presence of diabetes mellitus and ED. The presence of ED is also associated with the patient's overall diminished satisfaction with life. This has a direct impact on the approach to male patients in the consultation. Many males are hesitant to discuss, and many physicians ignore asking about ED. However as this study suggests doing so can impact on the patient's overall quality of life, especially as we now have safe and effective treatments for ED. It was interesting that we could determine an association between ED and the presence of diabetes mellitus but not between the number of years the patient had diabetes and ED. This suggests that we may be making the diagnosis of diabetes very late when neurological injury is already significant. One result stands out, that is the increased ED among the afro-Trinidadian population. This is not easy to explain since it is the indo-Trinidadian that historically bears the burden of diabetes and early heart disease, the result of vascular disease. One might expect to find an ethnic association favouring the indo-Trinidadian with respect to ED. It is not clear whether this is a true difference or the observation was because of ethnic differences in help-seeking behaviour. Further research, such as a community-based survey would help to clarify any true association between ethnicity and ED ...

A cross-sectional study was conducted to determine the prevalence and characteristics of Escherichia coli, Staphylococcus aureus, Bacillus spp. and Salmonella spp. in "bara", "channa", condiments/spices and ready-to-eat "doubles" sold by vendors in the St. George and Caroni counties of Trinidad. Of 196 samples of each of "bara", "channa", condiments/spices and ready-to-eat "doubles" examined, E. coli was detected in 0 (0.0 per cent), 14 (7.1 per cent), 96 (49.0 per cent) and 67 (34.2 per cent), respectively; Staphylococci were isolated from 104 (53.1 per cent), 71 (36.2 per cent), 129 (65.8 per cent) and 123 (62.8 per cent) samples, respectively; and Bacillus spp. were recovered from 22 (11.2 per cent), 85 (43.4 per cent), 100 (51.0 per cent) and 88 (44.9 per cent) samples, respectively. Salmonella spp. were not isolated from any sample. Of the 177 isolates of E. coli recovered from all sources, 9 (5.1 per cent), 7 (4.0 per cent) and 47 (26.6 per cent) were mucoid, haemolytic and non-sorbitol fermenters (NSF), respectively, but none agglutinated with O157 antiserum. Of 427 staphylococcal isolates, 130 (30.4 per cent) were confirmed as S. aureus of which 20 (15.4 per cent) were haemolytic and 84 (64.6 per cent) pigmented, while 17 (20.7 per cent) of 82 strains of S. aureus tested produced enterotoxins. Ready-to-eat "doubles", a popular food in Trinidad, therefore pose a potential health risk to consumers due to the high level of contamination with bacteria.

OBJECTIVE: To determine the difference in hearing between a group of steelband musicians (pannists) and a control group. DESIGN, SETTINGS, AND SUBJECTS: We conducted a controlled cross-sectional pilot study consisting of 29 steelpan players and 30 control subjects from a steelpan orchestra (steelband) in the Otolaryngology Department of the Eric Williams Medical Sciences Complex. RESULTS: Significantly more steelpan players had a hearing loss than the control subjects at 3000 Hz, 4000 Hz, and 6000 Hz ( P < 0.01). chi 2 testing for trend demonstrated that the longer a steelpan player played his instrument the greater the hearing loss. CONCLUSION: These results indicate that pannists suffer permanent auditory damage from high-intensity sound levels and that preventative measures are required to prevent this hearing loss, particularly in younger players.

OBJECTIVE: To identify risk factors for urinary tract stones in Trinidad and Tobago. METHODS: A consecutive series of patients presenting to institutions in Trinidad for the management of proven urinary tract calculi was interviewed by questionnaires designed to obtain data on age, gender, ethnicity, occupation, stone location, a family history of stone disease, a past history of certain medical diseases and a semiquantitative estimate of the magnesium intake in food, 'over the counter' drugs and drinking water. An equivalent number of patients attending the same institutions for follow-up and verified from hospital records as having a previous radiological diagnosis of urinary tract stones, as well as a group of asymptomatic members of the community working in the same area, underwent the same interview. Chi-square, anova and Kruskal-Wallis tests were used to examine differences between the groups. Multiple logistic regression analysis was used to determine persistence of the significance of these differences after controlling for confounding variables. RESULTS: Data sufficient for analysis were obtained for 122 previous and 102 prospective patients and 102 controls. The mean age of the patients was 32 years. The ratio of males to females was 0.9-1.8:1 for the affected groups, but significantly more males than females had calculi in the lower urinary tract (19%vs. 6%; P = 0.004). More patients (30%) than controls (7%) gave a positive family history of urinary tract stone disease (P < 0.001). Affected persons had a lower dietary magnesium intake (P = 0.003), which accounted for a significantly lower total magnesium intake (P = 0.02). Logistic regression analysis of the variables studied indicated that independent predictors of the disease were a positive family history (P = 0.001), total magnesium intake (P = 0.001) and age (P < 0.001). CONCLUSION: A low magnesium intake and a positive family history are highly predictive of urinary tract calculi in this population.

SETTING: At the Faculty of Medical Sciences, The University of the West Indies, St Augustine first-year students take two courses in health communication. In the Centre for Medical Sciences Education students completed a course experience questionnaire. This instrument is potentially useful in evaluating innovative programmes and securing support for their development. CONTEXT: The Faculty of Medical Sciences, The University of the West Indies, St Augustine was the first of three campuses to introduce compulsory health communication courses in 1995. Using a modified form of the 25-item course experience questionnaire (CEQ25) (Broomfield & Bligh, 1998) normally employed in overall degree or course evaluation, this study developed a 30-item questionnaire (CEQ30) to test its applicability to the evaluation of medical communication skills teaching MEASURES: In 1997 - 1998 medical, dentistry, veterinary medicine and pharmacy students completed the original short form of the CEQ25 including five items specific to medical communication skills teaching. Students used a five-point Likert scale ranging from one, indicating that they strongly disagreed with the statement, to a score of five, reporting that they strongly agreed with the statement. Principal Components Analysis with Varimax rotation analysed the scale structure of the evaluation tool. RESULTS: The principal components factor analysis of responses (n = 165) broadly confirmed five of Broomfield and Bligh's six factors, but identified a sixth factor in their original instrument (appropriate assessment) that split into two, and a seventh factor, use of available materials and resources. CONCLUSION: The modified CEQ30 is a reliable instrument with which to evaluate a course in medical communication skills, and encourage reflection on teaching and course design. Its use is applicable to medical courses during overall curriculum change and innovation in a medical school.

The aim of this study was to investigate sources of stress and psychological disturbance in dental students across the five years of undergraduate study at a dental school in Trinidad. Eighty-three percent of students completed a modified version of the Dental Environment Stress questionnaire (DES) and the Brief Symptom Inventory (BSI). On a scale ranging from 0 (not stressful) to 5 (highly stressful), overall mean DES scores for each of the five years of study were 1.58, 1.83, 2.65, 2.39, and 2.61 respectively, suggesting that levels of stress increase over the five years with a noticeable spike at the transition between the preclinical and clinical phases. Significant differences were found between specific stressors across the five years of study. Seven specific stressors and the stressor domains of Academic work and Clinical factors were more stressful for female students (t-test p < 0.05). The Global Severity Index of the BSI indicated that 54.8 percent of males and 44.2 percent of females were in the clinical range indicating significant psychological disturbance. Psychological disturbance was significantly associated with stress levels for male students (Spearmans rank correlation r = 0.56; p < 0.001), but not generally for female students. Further development is needed of dental educational programs that enhance students' psychosocial well-being.

STUDY OBJECTIVES: Following the development of the Caribbean Guidelines for Asthma Care, we examined the utilization of inhaled medications in asthmatic patients in Trinidad, West Indies. SETTING: Chest Clinic, Ministry of Health, Trinidad. PARTICIPANTS: Physician-diagnosed asthmatic patients who attended the Chest Clinic between July 1998 and August 2000. MEASUREMENTS AND RESULTS: A consecutive sample of patients who were > 7 years of age (n = 402) was interviewed about compliance with, understanding of, and use of inhaler medication. The inhaler technique of these patients was directly observed. Inhaled steroid therapy was prescribed in 83% of patients but were prescribed the least in elderly patients (63%) and children (62%). Salbutamol was prescribed in 98% of patients, and ipratropium and sodium cromoglycate were selectively prescribed in elderly men and children, respectively. Only 33% of patients used the inhaler correctly, and children and the elderly were the least efficient in its use. The use of a spacer device was advised in 19% of patients, including only 6% of the elderly patients. Explanations for different inhaler therapies were given to 62% of patients, and 53% of patients could describe these reasons. The reported 40% noncompliance rate among patients in the sample was primarily a result of long waiting periods at the pharmacy (58%) and the personal cost incurred on purchasing the medication (52%). CONCLUSIONS: Educating patients, with a focus on children and the elderly, in inhaler techniques and reinforcing understanding of asthma medications can improve asthma management in Trinidad. Asthma caregivers in the Caribbean should ensure the appropriate dissemination of the guidelines and should outline strategies for their implementation.

A cross-sectional study was conducted to determine the microbial quality of local and imported brands of bottled water available in supermarkets, groceries, and parlours in Trinidad. A sample size of 344 bottles of water was determined by using a precision rate of 2 percent and a Type 1 error of 5 percent. These bottles were purchased from six geographical regions in Trinidad which represented the whole island. The membrane filter technique was used with cultures made on endo agar and Fc agar for total coliforms and faecal coliforms, respectively. Total aerobic plate count (TAPC) was determined on nutrient agar, Pseudomonas aeruginosa and Salmonella spp were assayed using standard methods. Of the 344 water samples tested, 239 (69.5 percent) and 105 (30.5 percent) were local brands and imported brands, respectively. Eighteen (5.2 percent) of 344 samples were contaminated by coliforms with a mean count of 0.88 2 ñ 6.38 coliforms per 100 ml while 5(1.5 percent) samples were contained Escherichia coli. The prevalence of total coliforms in local brands of bottled water was 7.5 percent (18 of 239) compared with 0.0 percent (0 of 105) detected in imported brands. The difference was statistically significant (p= 0.004). Similarly, the prevalence of aerobic bacteria in local brands of bottled water (34.7 percent) was significantly (p= 0.001) higher than that found in imported brands (17.1 percent). Among local brands, the prevalence of total coliforms ranged from 0.0 percent to 13.8 percent but the difference was not statistically significant (p= 0.121). However, the prevalence of aerobic bacteria among these local brands ranged from 5.0 percent to 88.5 percent and the difference was significant (p< 0.0001). All water samples tested were negative for faecal coliforms, Salmonella spp and P aeruginosa. It was concluded that based on the recommended zero tolerance for coliforms in potable water, 5 percent of bottled water sold in Trinidad could be considered unfit for human consumption. The need to implement national standards for bottled water in Trinidad cannot be over-emphasized. (AU)

We retrospectively reviewed the clinical presentation and five-year mortality of 64 consecutive adults who underwent echocardiography at the Eric Williams Medical Sciences Complex between January 1992 and December 1994 with a left ventricular ejection fraction < 40 percent. The mean age was 60ñ12 years and 68 percent of patients were male. The prevalence of diabetes mellitus and hypertension was 40 percent and 46 percent, respectively. The mean left ventricle ejection fraction was 30ñ9 percent. The most common primary cost of left ventricular failure was coronary artery disease (CAD) in 47 percent, idiopathic dilated cardiomyopathy (9 percent), hypertensive heart disease (9 percent), alcohol related dilated cardiomyopathy (8 percent) and valvular heart disease (6 percent). Angiotensin converting enzyme inhibitors were prescribed in 85 percent of cases, diuretics (82 percent), digoxin (61 percent), warfarin (18 percent), beta blockers (10 percent), and amiodarone (8 percent). Survival data were available for 84 percent. Mortality was 53 percent at 5 years. Independent predictors of mortality were age, the use of beta blockers and left ventricular internal diameter. In conclusion, CAD was the most common cause of left ventricular failure. Five-year mortality was high, particularly in elderly patients with marked ventricular dilatation. (AU)

The purpose of this study was to determine the occurrence of coronary artery disease risk factors in patients presenting with acute myocardial infarction(AMI) to a tertiary care institution in Trinidad and to determine the factors associated with increased mortality following AMI. All patients admitted to the Eric Williams Medical Sciences Complex (EWMSC) between January 1 and December 31, 1996, with a diagnosis of AMI were identified using the hospital admissions and discharge diagnosis databases. Demographic, clinical and laboratory variables were extracted from the hospital case records of patients with confirmed AMI. Sixty-one AMI patients (38 men) were admitted during the study period. Mean age of admittance was 60 ñ 11 years with an ethnic case mix of thirty-nine (62 percent) of East Indian descent, eight (13 percent) of African descent, twelve (20 percent) mixed ethnicity and three of Caucasian descent. Thirty patients (49 percent) were hypertensive. Thirty-two patients (53 percent) were diabetic and eighteen patients (30 percent) gave a history of cigarette smoking. The mean left venticular ejection fraction was 53 ñ 14 percent. The mean serum cholesterol from 29 patients was 228.2 ñ 49.0 mg/dl. Increasing age, female gender, an ejection fraction less than 40 percent, non treatment with streptokinase and in-hospital ventricular fibrillation were associated with poor survival. Multiple regression analyses identified three independent predictors of mortality. These were gender (p = 0.04), in-hospital ventricular fibrillation (p = 0.001) and an ejection fraction less than 40 percent (p = 0.02). Diabetes mellitus, hypertension, hyperlipidaemia and cigarette smoking were prevalent amongst patients presenting with AMI. Ventricular function was a major determinant of two-year mortality following AMI. Aggressive risk factor modification is recommended to prevent both first and recurrent coronary events.(AU)
