RESUMO

Background: Haemagogus janthinomys is a primary sylvan vector of yellow fever virus and the emerging Mayaro virus. However, despite its medical importance, there is a dearth of data on the molecular taxonomy of this mosquito species. Methods: In this study, DNA barcoding analysis was performed on 64 adult female mosquitoes from Trinidad morphologically identified as Hg. janthinomys. The mitochondrial cytochrome c oxidase I (COI) gene and ribosomal DNA internal transcribed spacer 2 (ITS2) region of the mosquitoes were PCR amplified and sequenced, and molecular phylogenies inferred. Results: The BLASTN analysis showed that only 20% (n = 13/66) of COI sequences had high similarity (>99% identity) to Hg. janthinomys and the remaining sequences had low similarity (<90% identity) to reference GenBank sequences. Phylogenetic analysis of COI sequences revealed the presence of four strongly supported groups, with one distinct clade that did not align with any reference sequences. Corresponding ITS2 sequences for samples in this distinct COI group clustered into three clades. Conclusions: These molecular findings suggest the existence of a putative new Haemagogus mosquito species and underscore the need for further, more in-depth investigations into the taxonomy and classification of the Haemagogus genus.

RESUMO

OBJECTIVE: This study aimed to develop a sound database for the hematological reference intervals of thoroughbred foals in Trinidad, West Indies from birth to 1 month of age. ANIMALS: 89 foals. METHODS: Whole blood samples were taken from 89 foals throughout Trinidad at approximately 1 day, 1 week, and 1 month of age. These foals were examined to be classified as healthy or free from disease. Complete blood count (CBC), microscopic analysis of blood smears, and conventional PCR for Theileria equi and Babesia caballi were performed. RESULTS: Of the 89 foals, 67 were deemed healthy and suitable for establishing reference intervals. Foals in this study had lower mean hemoglobin and hematocrit values for all 3 times of sampling when compared to their North American counterparts. Age had a significant effect on hemoglobin, hematocrit, white blood cell (WBC), neutrophil, and platelet counts of the foals from birth to 1 month of age. CLINICAL RELEVANCE: Variations in reference intervals can occur due to differences in demographic, physiological, and environmental factors such as age, gender, breed, and geographical location. Given the changes in the hematological values over time, this study provides clinicians with valuable information that can be used to monitor the health status of newborn foals and detect disease conditions.

RESUMO

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.

RESUMO

BACKGROUND: The aim of this study was to measure the patient's perception of patient centeredness in their consultations for non-communicable diseases (NCDs). We also measured consultation length and patient enablement. METHOD: A cross-sectional study was conducted over 2 months at four primary care clinics at the St. Joseph cluster of the North Central Regional Health Authority (NCRHA) in Trinidad and Tobago. Interviewers timed the consultation and completed post-consultation questionnaires using the Patient Perception of Patient-Centeredness (PPPC) questionnaire and the Patient Enablement Index (PEI). The PPPC is a 14-item (each scored 1-4) Likert-scaled instrument. The total score is averaged and a PPPC score of 4 is the maximum. The PEI measures the ability of the patient to cope with life and their disease. The PEI consists of 6 questions scored 0-2, with a maximum score of 12. RESULTS: There were 180 respondents (response rate = 82.5%). Participants were female (75.6%), aged over 65 years (50.6%), married (51.1%), Indo-Trinidadian (52.2%), and Christian (60.6%). Half achieved a primary school education, and 37.2% secondary. The consultation length ranged between 1.32 and 31.22 min. The average, median and mode of the consultation length were 8.5, 7.74 and 10 min, respectively. The average, median and mode of the measures of patient-centeredness were PPPC (3.67, 3.86 and 4) and PEI score (5.93, 6 and 6). The PPPC average was lower in patients with a stroke (p = 0.022), and higher among those with more than 2 consultation interruptions (p = 0.015) and those who knew the doctor very well (p = 0.015). The PEI score was lower in patients with heart disease (p = 0.022). The consultation length was longer in those with tertiary education (p = 0.044) and those with two consultation interruptions (p = 0.032). PPPC Average and PEI Score correlated well (ρ = 0.408, p < 0.001). The consultation length correlated with the PPPC Average (ρ = 0.168,p = 0.025). CONCLUSION: Primary Care consultations in this cluster of health centres in NCRHA in Trinidad were often patient centered. The consultation length, patient-centeredness, measured with the PPPC instrument, and patient enablement scores, measured with the PEI instrument, in consultations for NCDs in Trinidad compare favourably with international reports.

RESUMO

BACKGROUND: Preconception care (PCC) is the term used for activities and interventions designed to address and prevent problems related to pregnancy, the neonatal period and childhood. This study assessed maternal health status prior to conception in Trinidad by means of a screening tool, physical measurements, and laboratory samples. METHODS: A cross-sectional study was conducted among women aged 18-45 years at a primary care centre in Arima, Trinidad. A de novo PCC screening tool was used to assess 13 domains of high-risk pregnancy in participants. These domains included dietary details, gynaecological and obstetric histories, and genetic and vaccination histories, among others. Blood pressure, weight, height, and waist circumference were recorded, and a capillary blood sample was used to determine random blood glucose and HbA1c levels. All data were coded and entered into SPSS ver. 21. RESULTS: A total of 400 nongravid participants were recruited, of whom 366 were included in the final analysis. Most (96.7%) had one or more risk factors for adverse pregnancy outcomes. These included overweight (27%), obesity (35%), central obesity (69.4%), and impaired glucose tolerance/diabetes mellitus (IGT/DM) (26.2%). Additionally, a sedentary lifestyle and diet high in processed food/fats were self-reported by 74.9% and 88.8% of participants, respectively. Only 13.1% had planned to conceive, and of those who had no immediate plans to conceive, 76.4% were currently sexually active, and many (60.7%) did not use birth control techniques. More than half (57.1%) had never had a pap smear. On the other hand, 86.3% knew their HIV status. Self-reported percentages for vaccination were as follows: MMR (100%), tetanus (17.5%), hepatitis B (11.5%) and influenza (2.7%). The majority (82.8%) of participants had not visited the dentist in the past year, with 35.9% of these individuals reporting symptoms of periodontitis. Segments of the population had multiple risk factors; for example, 23.7% of participants were overweight or obese and had an elevated HbA1c level. CONCLUSIONS: Unexpectedly, most participants had a risk factor for an adverse pregnancy outcome, and many had multiple risk factors. There is a strong case for enhanced preconception care for women in Trinidad.

RESUMO

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.

RESUMO

Phenytoin (DFH), is an anticonvulsant widely used for the treatment of different types of seizures.(1) Therapeutic monitoring (TDM) is required for DFH due to its narrow therapeutic range and nonlinear pharmacokinetics, among other characteristics. Monitoring is frequently done on plasma or serum (total drug) through immunological methods. DFH can also be monitored in saliva, which shows a good correlation with plasma. The concentration of DFH in saliva reflects the concentration of free drug and due to the simplicity in its collection, it leads to a less stressful process for the patient. The aim of this study was to validate the immunological method of kinetic interaction of microparticles in solution (KIMS) for the determination of DFH using saliva as biological matrix. Linearity, precision, detection and quantification limit, accuracy and interference were analyzed. Infostat 8.0 student version software was used for statistical analysis. The method was linear in a range between 0.41 and 5ug/ml. The detection and quantification limits were 0.14 and 0.45ug/ml, respectively. The equation of the straight line obtained based on the method comparison between KIMS and HPLC-UV was DFHKIMS= 0,81* DFHHPLC ­ 0,03.  The KIMS method proved to have the necessary analytical characteristics to be applied as a useful and practical tool for the follow-up of those patients with difficult venous access and/or children with chronic DFH treatments.


La Fenitoína (DFH), es un anticonvulsivante ampliamente utilizado para el tratamiento de distintos tipos de convulsiones.(1) El monitoreo terapéutico (TDM) es requerido para la DFH debido a su estrecho rango terapéutico y farmacocinética no lineal, entre otras características. Los monitoreos se realizan frecuentemente en plasma o suero (droga total) a través de métodos inmunológicos. También se puede monitorear DFH en saliva, la cual presenta una buena correlación con el plasma. La concentración de DFH en saliva refleja la concentración de droga libre y debido a la simplicidad en su recolección, conlleva a un proceso menos estresante para el paciente. El objetivo del trabajo fue validar el método inmunológico de interacción cinética de micropartículas en solución (KIMS) para la determinación de DFH usando como matriz biológica saliva. Se analizó linealidad, precisión, límite de detección y cuantificación, exactitud e interferencia. Se utilizó el software Infostat 8.0 versión estudiantil para el análisis estadístico. El método fue lineal en un intervalo entre 0,41 y 5ug/ml. Los límites de detección y cuantificación fueron 0,14 y 0,45ug/ml respectivamente. La ecuación de la recta obtenida en base a la comparación de métodos entre KIMS y HPLC-UV fue DFHKIMS= 0,81* DFHHPLC - 0,03.  El método KIMS demostró tener las características analíticas necesarias paran ser aplicada como herramienta útil y práctica para el seguimiento de aquellos pacientes de difícil acceso venoso y/o niños con tratamientos crónicos con DFH.

RESUMO

During a survey in Trinidad and Grenada for putative vectors of palm lethal decline phytoplasmas, three species of planthopper in the genus Melanoliarus (Hemiptera, Cixiidae) were collected. Melanoliarus maidis was collected from coconut palms in Grenada, M. kindli was collected from grasses in a coconut plot in Trinidad and a new species of Melanoliarus was collected from coconut palms in Trinidad. Herein the novel taxon is described with supplementary molecular data for the cytochrome c oxidase subunit I (COI) gene, 18S rRNA gene, and histone 3 (H3) gene to support placement in the genus Melanoliarus in the strict sense.

RESUMO

Phalaena militta Stoll, [1781], currently in the combination Thyrgis militta, is transferred to the new combination Calodesma militta. Phalaena militta is the type species of Thyrgis Walker, 1854, and so Thyrgis is a junior synonym of Calodesma Hübner, [1820]. The reinstated genus Seileria Dognin, 1923 is the next available name for the genus previously known as Thyrgis, and the remaining eight species and their subspecies currently in Thyrgis are transferred to new combinations as species of Seileria: S. angustifascia (Hering, 1925), S. basipunctata (Hering, 1926), S. constrictifascia (Dognin, 1919), S. flavonigra (Dognin, 1910), S. investigatorum (Toulgoët, 1988), S. marginata (Butler, 1875), S. meres (Druce, 1911), S. phlegon (Druce, 1885), S. phlegon ruscia (Druce, 1895), S. tenuifascia (Hering, 1930) and S. tenuifascia daguana (Hering, 1930). Eucyanoides Toulgoët, 1988, currently a synonym of Thyrgis, is made a new subjective synonym of Seileria. Based on DNA barcodes, we recognise three very similar, sexually dimorphic and in two cases polymorphic South American species of Calodesma with some phenotypes in common but very similar male genitalia: C. militta (BOLD:AAK1660), C. sp. cf. collaris (BOLD:ABZ2392) and C. pseudocollaris Cock new species (BOLD:AEI2170). Calodesma militta is widespread in South America, with two male morphs (collaris and dioptis) and two female morphs with variable markings (white and orange morphs). Centronia plorator Kaye, [1923] and Thyrgis lacryma Dognin, 1919 are variants of the white female morph and are new synonyms of Calodesma militta. A third female morph with red markings was not sequenced and could not be allocated to a species. Calodesma sp. cf. collaris (BOLD:ABZ2392) occurs in southern South America with both male morphs but only a white female morph. Calodesma pseudocollaris new species (BOLD:AEI2170) is only known from Trinidad, with one male morph (collaris) and the white female morph. Although more than ten morphs relating to this complex have been described as species, they cannot be synonymised without more data on distribution of the different species or DNA barcodes from the type specimens. Collated life history information indicates species of this group are split between Malpighiaceae feeders and Bromeliaceae feeders, but more work is needed to define these differences. The morphism patterns observed are discussed in terms of Müllerian mimicry and mimicry rings, and we suggest that in Trinidad (and elsewhere) there is a loose mimicry ring of diurnal black species with white spots or transparent patches on the wings which are most conspicuous and frequently observed when feeding on white Asteraceae flowers.

RESUMO

Klebsiella pneumoniae and Klebsiella quasipneumoniae are closely related human pathogens of global concern. The more recently described K. quasipneumoniae shares similar morphological characteristics with K. pneumoniae and is commonly misidentified as this species using traditional laboratory techniques. The vast mobilome in these pathogenic bacteria influences the dissemination of virulence factors in high-risk environments and it is, therefore, critical to monitor strains for developing effective clinical management strategies. Herein, this study utilized Illumina sequencing to characterize the whole genomes of nine clinical K. pneumoniae and one K. quasipneumoniae isolate obtained from patients of 3 major hospitals in Trinidad, West Indies. Reconstruction of the assembled genomes and implementation of several bioinformatic tools revealed unique features such as high pathogenicity islands associated with the isolates. The K. pneumoniae isolates were categorized as classical (n = 3), uropathogenic (n = 5), or hypervirulent (n = 1) strains. In silico multilocus sequence typing, and phylogenetic analysis showed that isolates were related to several international high-risk genotypes, including sequence types ST11, ST15, ST86, and ST307. Analysis of the virulome and mobilome of these pathogens showed unique and clinically important features including the presence of genes associated with Type 1 and Type 3 fimbriae, the aerobactin and yersiniabactin siderophore systems, the K2 and O1/2, and the O3 and O5 serotypes. These genes were either on or in close proximity to insertion sequence elements, phage sequences, and plasmids. Several secretion systems including the Type VI system and relevant effector proteins were prevalent in the local isolates. This is the first comprehensive study investigating the genomes of clinical K. pneumoniae and K. quasipneumoniae isolates from Trinidad, West Indies. The data presented illustrate the diversity of Trinidadian clinical K. pneumoniae isolates as well as significant virulence biomarkers and mobile elements associated with these isolates. Additionally, the genomes of the local isolates will add to global databases and thus can be used in future surveillance or genomic studies in this country and the wider Caribbean region.

RESUMO

Our aim was to determine the incidence disseminated histoplasmosis and cryptococcal antigenemia among 280 patients with a CD4<350 cells/mm3 attending a large HIV clinic in Trinidad over the period November 2021-June 2022. Sera were screened for cryptococcal antigen (CrAg) using the Immy CrAg Immunoassay (EIA) and the Immy CrAg lateral flow assay (LFA). Urine was screened for Histoplasma antigen using the Immy EIA and the Optimum Imaging Diagnostics (OIDx) LFA. For the purposes of analysis, it was assumed, that all patients with positive urine Histoplasma antigen tests by both EIA and LFA and those with a single positive urine Histoplasma antigen test and clinical features of disseminated histoplasmosis were true positives. The incidence of probable disseminated histoplasmosis and cryptococcal antigenemia were 6.4% (18/280) and 2.5% (7/280) respectively. The sensitivity and specificity of the Immy Histoplasma EIA were 100% (95% CI, 81.5%-100%) and 98.5% (95% CI, 96.1% - 99.6%) respectively as compared to the OIDx Histoplasma LFA of 88.9% (95% CI, 65.3% - 98.6%) and 93.9% (95% CI, 90.3% - 96.5%) respectively, with substantial agreement between the 2 test kits (Kappa value = 0.763; 95% CI 0.685, 0.841). Testing for disseminated histoplasmosis in HIV patients is important in endemic areas.

RESUMO

A 3-year-old, female, domestic shorthair cat, was presented to the Veterinary Teaching Hospital at the School of Veterinary Medicine (SVM), Trinidad and Tobago for a swollen nose, and multiple, variably sized small masses on both ears. The initial diagnostic tests included a CBC, serum biochemistry profile, cytological evaluation of masses on the ear and nose, and FeLV/FIV testing. The CBC and biochemistry results were unremarkable except for a hyperproteinaemia and hyperglobulinemia. Cytology of the nose and ear lesions revealed mixed inflammation and high numbers of intracellular and extracellular organisms consistent with Leishmania amastigotes. The cat was FeLV/FIV negative. Histopathology and Leishmania IFA and PCR analysis were subsequently performed, confirming the Leishmania diagnosis. The PCR, DNA sequencing and phylogenetic tree analyses identified L. amazonensis. This is the first reported case of L. amazonensis infection in a domestic animal in Trinidad with molecular characterization indicating it exists in the region and is likely being transmitted by sandflies.

RESUMO

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.

RESUMO

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.

RESUMO

La fièvre jaune est endémique dans plusieurs pays d'Amérique latine. Afin d'aider les décideurs à hiérarchiser les actions de prévention contre cette maladie, l'Organisation panaméricaine de la santé présente ces profils de pays avec une sélection concise et complète de données provenant des pays endémiques. Chaque profil fournit une analyse de la situation actuelle du pays, des facteurs écologiques et climatiques associés à la maladie, de la distribution et de l'incidence des vecteurs, ainsi que des principales activités des arbovirus. Il comprend également une perspective historique de l'épidémiologie et un résumé de la situation de la vaccination contre la maladie dans le pays.

RESUMO

Freshwater resources supply has always presented challenges and considering a changing climate quantifying the available water in the future is important. In the Caribbean, based on projections it is likely that the island of Trinidad would receive less intense rainfall, experience more dry days, become drier and warmer, and the water resources be decreased. In this study, the impact of a changing climate on the Navet Reservoir in Trinidad was investigated and reservoir volumes were quantified for the period 2011-2099. This period was subdivided into three time periods, 2011-2040, 2041-2070, and 2071-2099, and evaluated under the representative concentration pathways (RCPs): RCPs 2.6, 4.5, 6.0, and 8.5. Utilizing a calibrated/validated Soil Water Assessment Tool (SWAT) model for the Navet Reservoir together with projections from five general circulation models (GCMs), future monthly and seasonal reservoir volumes were estimated. The GCM precipitation and temperature data were bias-corrected using linear scaling and variance scaling methods. It was found that reservoir volumes are likely to be the lowest during the period 2041-2070 at the Navet Reservoir. Additionally, the projected reservoir volumes are reliable, resilient, and not vulnerable. These results may be used by water managers in the adaptation and mitigation of the impacts of a changing climate, thus, building resilience in the water sector.
