Anatomical variations in the circle of Willis on magnetic resonance angiography in a south Trinidad population.

Objectives: This article seeks to determine the prevalence of a complete circle of Willis (CoW) and its common morphological variations in a south Trinidad population, while also investigating the influence of gender, age, and ethnicity on CoW morphology. Methods: A prospective, descriptive, cross-sectional study was done on the magnetic resonance images for consecutive patients who had a brain MRI/magnetic resonance angiography at a tertiary health institution in south Trinidad between October 2019 and September 2020. Patients with significant cerebrovascular disease and/or a history of prior neurosurgical intervention were excluded. Results: A complete CoW was seen in 24.3%, with more complete circles observed in younger participants (≤45 years) and Afro-Trinidadians. No gender predilection for a complete CoW was demonstrated. The most common variations in the anterior and posterior parts of the circle were a hypoplastic anterior communicating artery (8.6%, n = 13) and bilateral aplastic posterior communicating arteries (18.4%, n = 28), respectively. Conclusions: Significant variations exist in the CoW of a south Trinidad population with a frequency of complete in 24.3%, and more complete circles in younger patients and Afro-Trinidadians. Gender did not influence CoW morphology. Advances in knowledge: Structural abnormalities in the CoW may be linked to future incidence of cerebrovascular diseases and should therefore be communicated to the referring physician in the written radiology report. Knowledge of variant anatomy and its frequency for a particular populations is also required by neurosurgeons and neuro-interventional radiologists to help with preprocedural planning and to minimize complications.

Prevalence of CYP2C19*2 and CYP2C19*3 Allelic Variants and Clopidogrel Use in Patients with Cardiovascular Disease in Trinidad & Tobago.

INTRODUCTION: Trinidad & Tobago has the highest prevalence of cardiovascular disease (CVD) in the Caribbean and clopidogrel is a ubiquitously used treatment. Yet, the extent of genetically mediated clopidogrel resistance is unknown. To determine this, we investigated whether the association between CYP2C19*2 and CYP2C19*3 genetic variants and clopidogrel resistance holds, and calculated the frequencies of these in the Trinidadian CVD population. METHODS: Demographic data, clinical data, and a saliva sample were collected under informed consent from 22 patients with CVD on dual anti-platelet therapy whose biochemical resistance to clopidogrel is known, and a further 162 patients accessing the main public CVD clinic in Trinidad and who are either currently being treated or are likely to be treated with clopidogrel. A polymerase chain reaction (PCR) and restriction enzyme digestion procedure was used to genotype each patient for the CYP2C19*2 and CYP2C19*3 allelic variants. Genotype was compared to known clopidogrel resistance in the 22 patients, and to disease status and clopidogrel usage in the larger cohort. RESULTS: CYP2C19*2 genotype was concordant with clopidogrel resistance. CYP2C19*2 was detected in 61.1% (99/162) of patients and CYP2C19*3 was undetected. Clopidogrel was the most prescribed antiplatelet therapy (42%). A total of 120 people presented with coronary artery disease (CAD) and 52.5% of these (n = 63/120) are currently prescribed clopidogrel. 63.5% (40/63) of patients with CAD who are prescribed clopidogrel carry the CYP2C19*2 allele; ten homozygous and 30 heterozygous. Indian patients comprised 65% of the cohort and were four times more likely to carry the CYP2C19*2 allele than African patients. CONCLUSIONS: A large proportion of Trinidadian patients with CVD who are prescribed or may be prescribed clopidogrel carry genetic variants associated with clopidogrel resistance. These results emphasize the clinical need for further investigation into whether CYP2C19*2 genotype should guide clopidogrel use for the cardiovascular disease population in Trinidad & Tobago. A slide deck is available for this article.

Intimate Partner Violence and Suicidality: Applicability of General Strain Theory to Women in Trinidad and Tobago.

Suicide among women is a growing problem in Trinidad and Tobago. Despite efforts to reduce suicide, the etiology of suicidal behaviors in this region has rarely been examined. Using the National Women's Health Survey for Trinidad and Tobago in 2018 (n = 1,079), this study examined the causes of suicidality through concepts contained in Agnew's general strain theory, such as negative stimuli (i.e., intimate partner violence [IPV]) and negative emotion (i.e., depression). By estimating structural equation models, this study found that IPV was strongly related to depression and suicidality. Particularly, depression mediated the effect of IPV on suicidality.

Scope of optometry practice in Trinidad and Tobago: A cross-sectional study.

Background and Aim: To report the scope of optometry practice in Trinidad and Tobago to identify areas that need improvement. Methods: A cross-sectional study of optometrists in Trinidad and Tobago was conducted using a validated self-structured questionnaire. Data obtained was exported to the Statistical Package for Social Sciences. Descriptive analysis and Pearson χ 2 were used to summarize the demographic data and determine associations, respectively. Result: A total of 63 optometrists participated in the study. Majority of them were females (69.8%, n = 44), Christians (65.1%), East Indians (47.6%), and 30 years and below (66.7%). Most (87%) of them utilized routine optometric equipment in their clinical practice including autorefractors, retinoscopes, direct ophthalmoscopes, lensometers, phoropters, slit lamp biomicroscopes, trial lens boxes, and visual acuity chart projectors. A few of them have noncontact tonometer (4.8%), Volk lenses (1.6%), and perform color vision tests (1.6%). Fewer (12.7%, n = 8) practitioners provided low-vision services. The use of pharmaceutical agents was prevalent among the participants (55.6%). Additionally, the provision of contact lenses was the most frequently practiced service among the participants (85.7%, n = 54). A significant association was observed between the provision of low-vision services and sex (p = 0.03). Conclusion: The scope of optometry practice in Trinidad and Tobago is in accordance with the basic guidelines set out by the World Council of Optometry but there is need to get more involved in the provision of low vision and other specialty services.

Examining healthcare needs and decisions to seek health services among Venezuelan migrants living in Trinidad and Tobago using Andersen's Behavioral Model.

Introduction: Beginning in 2016, Trinidad and Tobago experienced increasing flows of migrants and refugees from Venezuela. Through a Government Registration Exercise in 2019, followed by a Re-registration Exercise in 2020, migrants and refugees benefitted from access to publicly available primary care and emergency medical services. By applying Andersen's Behavioral Model for Health Service Use, our study examined the non-communicable disease care needs of migrants, and factors influencing their decision to seek public and private health services. Method: Between September and December 2020, a health questionnaire was administered via telephone to n = 250 migrants from Venezuela. Descriptive statistics summarized the constructs of Andersen's Behavioral Model. The model comprised of predisposing factors including migrants' social characteristics; enabling factors namely monthly earnings, education level and most trusted source of information on medical needs; need for care factors such as migrants self-reported health status, presence of non-communicable health conditions and having visited a doctor in the past 12 months; and the outcome variables which were migrants' decisions to seek public and private health services. Pearson χ2 tests, odds ratios and multivariable logistic regression with backward elimination examined the factors influencing a migrant's decision to seek health services. Results: Overall, 66.8% of migrants reported they would seek public health services, while 22.4% indicated they would seek private health services. Predisposing factors namely length of time residing in Trinidad and Tobago (p = 0.031) and living with family/friends (p = 0.049); the enabling factor of receiving information from publicly available sources (p = 0.037); and the need for care factor of visiting a doctor for a physical health problem (p = 0.010) were significant correlates of their decision to seek care in the public sector. Predisposing factors namely living with family/friends (p = 0.020) and the enabling factor of having difficulty accessing healthcare services (p = 0.045) were significant correlates of their decision to seek care from private providers. Discussion: Our findings demonstrated the positive association between social networks and a migrant's decision to use public and private health services, thus underscoring the importance of family and friends in facilitating health service use, promoting proper health practices and preventing diseases. Overall, the use of Andersen's Behavioral Model aided in identifying the factors associated with the use of health services by Venezuelan migrants in Trinidad and Tobago. However, further studies are needed to better understand their need for ongoing care, to inform policy, and to plan targeted health interventions for addressing the gaps in health service access, barriers and use.

Experiences with SARS-CoV-2 (Covid-19) in Trinidad and Tobago, a small island developing state: realities and opportunities.

The COVID-19 pandemic has exerted significant global challenges that are expressed in a variety of socio-politico-economic scenarios, depending upon individual countries' preparedness and resilience. The impact COVID-19 in Small Island Developing States (SIDS), most of which are categorized as Lower and Middle-Income Countries, has been pronounced. Furthermore, many of these SIDS possess specific vulnerabilities to global threats. This paper contextualizes the experience of Trinidad and Tobago from some perspectives of geoeconomics, healthcare, and international relations. In many ways, the experience is similar to that of other SIDS with the inherent nuances of a post-colonial world. Trinidad and Tobago was ranked number one by the Oxford University COVID-19 Government Response Tracker (OxCGRT) "Lockdown rollback checklist: Do countries meet WHO recommendations for rolling back lockdown?". Despite the significant political support to combat the disease, by the end of 2022, the country had recorded over four thousand deaths and just over 50% of the population is vaccinated. This paper seeks to discuss the successes and challenges faced by this twin island state.

Differential Mental Health Impact of COVID-19 Lockdowns on Persons with Non-Communicable Diseases in Trinidad and Tobago.

Persons with chronic non-communicable diseases (NCDs) were identified as particularly at risk of severe morbidity and mortality during the COVID-19 pandemic. Little is written about the impact of COVID-19 on this sub-population in the Caribbean, where the prevalence of NCDs is disproportionately high. This study aimed to ascertain COVID-related concerns, and the mental health impact of the pandemic among persons with and without NCDs in Trinidad and Tobago, during the acute period of COVID-19 lockdowns early in the pandemic. An anonymous online survey collected cross-sectional data from a convenience sample nationwide. Of 1287 respondents, 219 self-identified as having an NCD. Findings suggest that the pandemic was experienced unequally by persons with NCDs, who were more likely to be concerned about health and wellbeing and to report health inequalities-unemployment, social isolation and negative effects of government restrictions. Compared to those without NCDs, they were more likely to increase use of marijuana during the lockdown period, and to report severe anxiety/depression that can result in exacerbation of NCDs. Interventions for persons with NCDs must address the mental health consequences of any pandemic, including increased drug use, and also address social inequalities to reduce sustained post-pandemic mental health impact and negative health outcomes.

COVID-19 Vaccine Hesitancy in Trinidad and Tobago: A Qualitative Study.

Background After three years of COVID-19, the WHO declared that the pandemic was no longer a global health emergency. Vaccination remains part of the management strategy, given the current phase of the pandemic. This study explored the reasons for COVID-19 vaccine hesitancy in Trinidad and Tobago (TT). Methodology A qualitative study of persons 18 years and over from the eastern, northwest, northcentral, and southwestern geographical areas of TT, who are unvaccinated and hesitant, was done by convenience sampling. Formal in-depth virtual interviews were done on a one-to-one basis using a semi-structured questionnaire. The interviews were recorded and transcribed using the principles of reflexive thematic analysis of participants' responses.  Results From 25 participants' responses, the main themes for being vaccine-hesitant were fear, inefficacy, information inadequacy, perceived susceptibility, mistrust, herbal alternatives, and religious hesitations. Additionally, their motivations for receiving the vaccine in the future were surrounded by themes of necessity, perceived susceptibility, health benchmark, and assurance. Conclusion and recommendations This qualitative investigation identified traditional factors contributing to COVID-19 vaccine hesitancy and unique determinants such as herbal use and religious beliefs within the TT context. These insights could inform future research and facilitate the development of tailored strategies to address persistent vaccine hesitancy for COVID-19.

Understanding the Burden of Kidney Failure in Trinidad and Tobago: A Review of the Epidemiological Data From a Regional Center.

Objective The aim of this study was to determine the incidence of new patients requiring renal replacement therapy and to gather data on sex, age, ethnicity, mortality, and causes of kidney failure in Trinidad and Tobago in comparison with the rest of the world. Method Electronic data were gathered for new patients initiating dialysis between January 1, 2016, and December 31, 2017, including the date of dialysis initiation, age, gender, ethnicity, diagnosis, dialysis access and modality, and outcome at three months and the end of the year. The data were analyzed using simple descriptive statistics via Microsoft Excel (Microsoft Corporation, Redmond, Washington, United States). Results Over a two-year period, 265 new patients underwent renal replacement therapy, of which 51.7% were 50-69 years of age, 53.9% were male, 46% were female, 67.9% were Afro-Trinidadian, and 38.1% had a combination of diabetes mellitus and hypertension as the cause of kidney failure. The incidence rates of treated end-stage renal disease (ESRD) globally in 2016 and 2017 were 306 and 224 per million population, respectively, and mortality for both years was 32% and 32.1%, respectively. Conclusion Our study showed that Trinidad and Tobago has one of the highest incidences of patients initiating renal replacement therapy and mortality rates.

Quality of life of MS patients in Trinidad and Tobago: Anomaly or adaptation?

BACKGROUND AND OBJECTIVE: There has been growing interest in quality of life associated with multiple sclerosis but the research has been overwhelmingly carried out in developed countries. This study aimed to assess quality of life of multiple sclerosis patients in Trinidad and Tobago. METHODS: All multiple sclerosis patients were asked to complete demographic, EQ-5D-5L and MSQOL-54 questionnaires. EQ-5D data were compared with population norms for Trinidad and Tobago. MSQOL-54 data were compared with results from a matching cohort of non-MS respondents. Regression analyses were used to explore the association between MSQOL-54 scales and EQ-5D utility. RESULTS: The 97 patients were mainly urban, highly educated and 75% female. EQ-5D-5L data showed more frequent and more severe problems and lower index values than the population and patients of other chronic illness clinics in Trinidad and Tobago. MSQOL-54 results showed that patients were more affected by physical items, but had high scores on mental and emotional items when compared with the matching cohort and patients in other countries. CONCLUSION: The low prevalence and demographics of patients suggest the possibility of undetected cases in rural areas and/or among less educated groups. Further investigation into the high levels of mental and emotional health among patients may lead to the design of interventions to help patients of multiple sclerosis and other illnesses.

Cancer morbidity and mortality trends in Trinidad and Tobago (2008-2018).

PURPOSE: Cancer is a leading cause of death in the Caribbean, and the Republic of Trinidad and Tobago is no exception. Evidence suggests that cancer incidence and mortality may vary based on demographic factors across the different cancer types. This study aimed to investigate the incidence and mortality trends associated with cancer cases in Trinidad and Tobago for the period 2008-2018, across different age groups, gender, and ethnicity. METHODS: Data on 15,029 incident cancer cases were reported to the Dr. Elizabeth Quamina Cancer Registry between 2008 and 2018. The retrospective data were analyzed by sex, ancestry, and age, and were reported using Trinidad and Tobago population statistics for the period 2008-2018. RESULTS: The incidence of prostate and breast cancers was high among males and females, respectively. Among males, the highest cancer mortality was associated with prostate, lung, colon, blood, and pancreatic cancers, respectively. Among females, the highest cancer mortality was associated with breast, ovary, colon, blood, and pancreatic cancers. The frequency of occurrence of the top five cancer sites was the highest among Afro-Trinidadians followed by Indo-Trinidadians. Most females diagnosed with breast cancer were at a localized stage, while most males diagnosed with breast cancer were at a distant or regional stage. Most individuals diagnosed with blood cancer were at a distant stage. For lung and colon cancer, the stage of diagnosis for most males and females was either distant or unknown. Majority of males are diagnosed with prostate cancer at an unknown stage. CONCLUSIONS: The findings indicate highest cancer incidence and mortality occur among Afro-Trinidadians. The stage at diagnosis varies across cancer types and gender.

Correlates and Predictors of COVID-19 Vaccine Hesitancy Among Persons Living With HIV in Trinidad and Tobago.

BACKGROUND: Persons living with HIV may be at risk of more severe forms of COVID-19 infection and minimizing health risks largely depends on their acceptance of the COVID-19 vaccinations. OBJECTIVE: This study examined the correlates and predictors of COVID-19 vaccine hesitancy among persons living with HIV in Trinidad and Tobago. METHODS: A cross-sectional survey using a structured interview was conducted. Data were compiled on patient socio-demographics, diagnosed chronic diseases, psychological factors, and decisions to take the COVID-19 vaccine. Pearson χ2 tests examined the associations between study variables and COVID-19 vaccine hesitancy, and multivariable logistic regression analyses examined its predictors. RESULTS: In this study, 84% were virally suppressed, i.e., HIV viral load <1000 copies/ml. COVID-19 vaccine hesitancy was found to be 39%. Univariate analysis showed that higher vaccine hesitancy was significantly associated with females (OR 2.02, 95% CI 1.23-3.33) and patients of mixed ethnicity (OR 1.84, 95% CI 1.07-3.15). In our multivariable analysis, psychological factors namely, confidence in the COVID-19 vaccine (OR 0.16, 95% CI 0.05-0.47), the perceived benefits of the vaccine (OR 0.54, 95% CI 0.37-0.79), and cues to action (OR 0.68, 95% CI 0.47-0.97) were observed as predictors of COVID-19 vaccine hesitancy. CONCLUSION: Psychological factors such as confidence in the COVID-19 vaccine, perceived benefits of the vaccine, and cues to action were possible predictors of COVID-19 vaccine hesitancy. This study underscored the continued need for strategies to increase confidence and knowledge about the benefits of taking the COVID-19 vaccine among persons living with HIV.

Antimicrobial Consumption from 2017 to 2021 in East Trinidad and Tobago: A Study in the English-Speaking Caribbean.

An antimicrobial consumption (AMC) study was performed in Trinidad and Tobago at the Eastern Regional Health Authority (ERHA). A retrospective, cross-sectional survey was conducted from 1 November 2021 to 30 March 2022. Dosage and package types of amoxicillin, azithromycin, co-amoxiclav, cefuroxime, ciprofloxacin, levofloxacin, moxifloxacin, nitrofurantoin and co-trimoxazole were investigated. Consumption was measured using the World Health Organization's Antimicrobial Resistance and Consumption Surveillance System methodology version 1.0, as defined daily doses (DDD) per 1000 population per day (DID). They were also analyzed using the 'Access', 'Watch' and 'Reserve' classifications. In the ERHA, AMC ranged from 6.9 DID to 4.6 DID. With regards to intravenous formulations, the 'Watch' group displayed increased consumption, from 0.160 DID in 2017 to 0.238 DID in 2019, followed by a subsequent drop in consumption with the onset of the COVID-19 pandemic. Oral co-amoxiclav, oral cefuroxime, oral azithromycin and oral co-trimoxazole were the most highly consumed antibiotics. The hospital started off as the higher consumer of antibiotics, but this changed to the community. The consumption of 'Watch' group antibiotics increased from 2017 to 2021, with a drop in consumption of 'Access' antibiotics and at the onset of COVID-19. Consumption of oral azithromycin was higher in 2021 than 2020.

The health and economic burden associated with sugar-sweetened beverage consumption in Trinidad and Tobago.

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.

Examining the Correlates of HIV Testing for Venezuelan Migrants in Trinidad.

An important preventive measure in the fight against the HIV epidemic is the adoption of HIV testing. The government of the Republic of Trinidad and Tobago conducted a registration exercise in 2019 for undocumented migrants and refugees from Venezuela residing in the country. These migrants were allowed access to the public health system. In this study, we observed the correlates of HIV testing in Venezuelan migrants residing in Trinidad. A convenience sample of n = 250 migrants was collected via telephone survey from September through December 2020. Variables of interest included social factors, health needs, and uptake of HIV testing. Pearson χ2 tests examined the associations between study variables, and multivariable logistic regression with backward elimination produced the odds of taking an HIV test. In our study, 40.8% of migrants reported having received an HIV test since arriving in Trinidad. Persons who migrated with family or friends had greater odds of getting an HIV test relative to persons who arrived alone (OR = 2.912, 95% CI: 1.002-8.466), and migrants who knew where to get an HIV test also greater odds of getting a test relative to person who did not know where to get a test (OR = 3.173, 95% CI: 1.683-5.982). Migrants with known physical health problems had greater odds of getting an HIV test relative to migrants without these health problems (OR = 1.856, 95% CI: 1.032-3.337). Persons who arrived with family or friends had greater odds of experiencing difficulties accessing public health care relative to persons who arrived alone (OR = 3.572, 95% CI: 1.352-9.442). Migrants earning between $1000 and $2999 TT per month had greater odds of experiencing trouble accessing public health services relative to persons who had monthly earnings of less than $1000 TT (OR = 2.567, 95% CI: 1.252-5.264). This was the first quantitative study on HIV testing among Venezuelan migrants in Trinidad. Migrants still experience difficulties accessing healthcare, which, in turn influences national HIV prevention and control efforts. The results gathered may help in developing HIV prevention plans that are led by a national health policy that takes migrant communities' needs into account.

Phylogenetic analyses of Salmonella detected along the broiler production chain in Trinidad and Tobago.

This study was conducted to determine the phylogenies of Salmonella strains isolated from cross-sectional studies conducted at hatcheries, broiler farms, processing plants, and retail outlets (broiler production chain) in Trinidad and Tobago over 4 yr (2016-2019). Whole-genome sequencing (WGS) was used to characterize Salmonella isolates. Core genome phylogenies of 8 serovars of public health significance were analyzed for similarities in origin and relatedness. In addition, Salmonella strains isolated from human salmonellosis cases in Trinidad were analyzed for their relatedness to the isolates detected along the broiler production chain. The common source of these isolates of diverse serovars within farms, within processing plants, between processing plants and retail outlets, and among farm-processing plant-retail outlet continuum was well-supported (bootstrap value >70%) by the core genome phylogenies for the respective serovars. Also, genome analyses revealed clustering of Salmonella serovars of regional (intra-Caribbean) and international (extra-Caribbean) origin. Similarly, strains of S. Enteritidis and S. Infantis isolated from human clinical salmonellosis in 2019 from Trinidad and Tobago clustered with our processing plant isolates recovered in 2018. This study is the first phylogenetic analysis of Salmonella isolates using WGS from the broiler industry in the Caribbean region. The use of WGS confirmed the genetic relatedness and transmission of Salmonella serovars contaminating chickens in broiler processing, and retailing in the country, with zoonotic and food safety implications for humans.

The Trinidad and Tobago Covid-19 Domestic Violence Victimization and Perpetration Study.

Purpose: While there is available scholarship in the Global North on DV victimization and perpetration during the COVID-19 pandemic, there is a dearth of similar scholarship in the Global South. With this in mind, the Trinidad and Tobago COVID-19 Domestic Violence Victimization and Perpetration study was conducted in an attempt to fill that void. Method: An online questionnaire containing a qualitative component was used to gather data aimed at determining whether DV victimization and perpetration had increased during the COVID-19 pandemic as well as possible contributory factors. Participants were 602 married or cohabiting adult citizens in Trinidad and Tobago. Results: The results indicated that overall there was an increase in DV perpetration (13%) as well as an increase in DV victimization (16%) among the sampled population. The results also indicated that males (17%) and females (13%) in the sample engaged in increased levels of DV perpetration, while males (25%) and females (12%) were victims of increased DV victimization. Six themes emanated from the qualitative component of the study, namely: isolation/Covid-19 restrictions, lack of assistance for victims, male fear of reporting DV, work as a safe space, mental health effects and job loss. Conclusion: The findings revealed increased DV perpetration and victimization among the study's participants. These findings have implications for policymakers in Trinidad and Tobago.

A Bibliometric Analysis of COVID-19 Scientific Literature From the English-Speaking Caribbean.

The COVID-19 pandemic has led to a global crisis and has affected the Caribbean islands, leading to significant health and socioeconomic consequences in this region. Efforts to mitigate the burden of this disease have led to an accelerated amount of research in the English-speaking Caribbean (ESC). This bibliometric analysis aimed to evaluate the COVID-19-related scientific literature from the ESC nations. A total of 175 articles were included and analyzed from an initial PubMed search (n = 638) for COVID-19-related scientific literature from the ESC nations published between January 1, 2020, and June 30, 2022. Microsoft Excel 2016 (Microsoft Corporation, Redmond, Washington) and the VOSviewer (version 1.6.18) were used to characterize countries, authorship, journals, affiliations, and keywords of the COVID-19-related articles. Trinidad and Tobago (38%), Jamaica (22%), Barbados (20%), and Grenada (15%) contributed to the greatest number of publications. The University of the West Indies (UWI) campuses in Trinidad and Tobago, Jamaica and Barbados, and St. George's University in Grenada were the most prolific institutions. Srikanth Umakanthan from the UWI was the most prolific author. Cureus, SN Comprehensive Clinical Medicine, and Frontiers in Public Health were the first three most productive journals; 59% of the 175 articles had either the first or last author affiliated with an institution in the ESC, and 19% of the articles were country-focused: Trinidad and Tobago (16/175), Jamaica (9/175), Barbados (5/175), and Antigua and Barbuda (2/175). Among the top themes of research, 27% were outbreak response and rearrangements, epidemiological studies (23%), clinical management (23%), and medical education (13%). Over the last two years, an interest stimulated by the pandemic has expanded the research in ESC countries. However, gaps in the knowledge exist, especially in the epidemiology of COVID-19 complications in the sub-populations of chronic non-communicable diseases, post-COVID syndrome, and the long-COVID syndrome in the region. Hence, there is enormous scope for more research across the region.

Investigating the leading reasons for primary health care encounters and its implications for health care in Trinidad and Tobago. A systematic review.

This systematic review aims at offering a comparative analysis of the leading reasons for encounters (RFEs) of patients presenting to primary care facilities. A systemic search was carried out using MEDLINE/PUBMED, CINAHL, Google Scholar, LILACS, and PROQUEST to identify the studies relevant to RFEs in primary health care in June 2020. Fifteen studies met the eligibility criteria which included originality, published between 2015 and 2020, listed two to five RFEs at a primary health care facility, and included patients with acute and/or chronic conditions. The mean total RFEs recorded were 6753.07 (Standard deviation = 17446.38, 95% Confidence Interval 6,753.0667 ± 8,829.088 [± 130.74%]). The most common RFE chapters recorded were Respiratory and Digestive chapters. The patients recorded fever as the most frequently reported RFE while cough was ranked as most common. The physicians reported hypertension as the most frequently reported and most common RFE. The most frequently physician and patient reported RFEs to the primary health care are hypertension and fever. Respiratory and Digestive were the most frequently reported chapters. The findings are useful for the proper implementation of services, facilities, and equipment utilized in Trinidad and Tobago primary health care.

Food insecurity in Venezuelan migrants in Trinidad and Tobago using the food insecurity experience scale.

Economic, political, humanitarian and health crises in Venezuela have resulted in mass out migration -thousands of Venezuelans emigrated to Trinidad and Tobago. However, little is known about their food security status in the host country. This study assessed the food security status among Venezuelan migrants and asylum seekers in Trinidad and Tobago and tested the validity of the online application of the food insecurity experience scale (FIES), a tool to measure food insecurity, in a small group. This convenience, cross-sectional study applied an online questionnaire to 433 Venezuelan migrants in Trinidad and Tobago in 2020. Snowball sampling was used to connect to migrants based on their access to locally-based NGO service providers, and organizations directly connected to the Venezuelan migrant community. Researchers applied the 12-month reference period to the FIES to measure food insecurity at the individual level. Descriptive analyses, Rasch modeling and binary logistic regression were conducted. Overall, 61.9% of respondents displayed behaviors characterized as severely food insecure. Significant differences in food security status were observed when categories of employment status (p = 0.032) and paying rent (p = 0.005) were considered. There were greater proportions of unemployed individuals who were severely food insecure (67.6%) compared to those who were employed (56.7%). There were greater proportions of individuals paying rent who were severely food insecure (62.6%) compared to those who were not paying rent (50.0%). Logistic regression with adjusted odds ratios and 95% confidence intervals revealed that food insecurity was less likely among migrants who were employed (OR 0.112, 95% CI 0.016-0.763) relative to those who were not employed, while food insecurity was more likely among migrants who were paying rent (OR 7.325, 95% CI 1.965-27.312) relative to those not paying rent. The FIES was consistent in assessing food security status. These findings provide a rapid assessment that can be used to galvanize international, national and community-level stakeholders to devise and target responses to assist migrants experiencing food insecurity.
