RESUMO
HIV-1, Hepatitis B and HTLV-1 have similar risk factors and shared routes of transmission and MSM are disproportionately affected by HIV. The aim of the study was to determine the prevalence of HTLV-1 and HBsAg positivity at initial enrolment among MSM attending a large HIV Clinic in Trinidad. Chart reviews were conducted between 2 and 15 January 2024, among self-identified MSM and a comparative group of randomly selected self-identified heterosexual males where sociodemographic, clinical and laboratory data were collected and analysed using SPSS Version 25. During the period April 2002-31 October 2023, in total there were 10,424 patients registered at the clinic, of whom 1255 (12.0%) were self-identified MSM, with an age range of 19-85 years and a median age of 40 years. There were 1822 randomly selected heterosexual males, with an age range of 18-94 years old and a median age of 52 years. Among the MSM, there were 21 (1.67%) patients who were HIV-1/HTLV-1-coinfected, 64 (5.10%) who were HIV-1/HBsAg-coinfected and two (0.16%) who were coinfected with all three viruses (HIV-1/HTLV-1/HBsAg) as compared to 47 ((2.58%) HIV-1/HTLV-1-coinfected (p = 0.12), 69 (3.79%) HIV-1/HBsAg-coinfected (p = 0.10) and three (0.16%) patients coinfected with all three viruses among the heterosexual males. There were no patients with HTLV-1-related diseases among the HIV-1/HTLV-1-coinfected patients and there were no deaths from chronic liver disease in patients coinfected with HIV-1/HBsAg. Despite the availability of an efficacious vaccine, there is a prevalence of hepatitis B of 5.1% among MSM attending the HIV Clinic in Trinidad; therefore, programmes to increase health literacy, screening and immunization are urgently needed.

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.

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.

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.

The freshwater ornamental fish trade represents a major contributor to the livelihoods of many producers in Trinidad and Tobago, with stocks destined for local, regional and international markets. A review of clinical cases presented to the Aquatic Animal Health Unit at the University of the West Indies, School of Veterinary Medicine for the period September 2010 to December 2012 suggested that piscine mycobacteriosis may be widespread throughout the local ornamental fish industry. Thus, to determine the prevalence of mycobacteriosis in ornamental fish sold in pet stores, a total of 122 specimens were sourced from 24 retail suppliers across Trinidad. Fish were killed and internal organs were examined for lesions suggestive of granulomas. All wet-mount slides were acid-fast stained, regardless of the presence or absence of observed granuloma-like lesions. Histological analysis was performed on one randomly selected whole specimen from each facility. Mycobacterium sp. was identified using real-time PCR detecting the 16S rRNA gene in tissue samples. Associations between parasitism, facility biosecurity and presence of positive animals were determined. The prevalence of Mycobacterium sp. infection was 61 ± 7% (74/122), with positive specimens being acquired from 54.2% (13/24) of facilities examined. Further, 100% of facilities did not employ optimum biosecurity measures.

BACKGROUND: Ideal cardiovascular health behaviour (CVHB) measures four ideal health behaviours (non-smoking, body mass index <85th Percentile, healthy diet, and physical activity). This study aimed to determine the prevalence, distribution, and correlates of ideal CVHB among adolescents in the Caribbean. METHODS: Nationally representative cross-sectional data of 2016 or 2017 with complete CVHB measurements were analysed from 7556 school adolescents from four Caribbean countries. RESULTS: The prevalence of 0-1 ideal metrics CVHB was 20.4%, 2 ideal metrics 48.7%, and 3-4 ideal metrics 30.8%. Only 5.0% had all 4 ideal CVHB metrics, 41.0% intermediate CVH (≥1 metric in the intermediate category and none in the poor category), and 54.0% had poor CVH (≥1 metric in poor category). In adjusted logistic regression analysis, compared to students from Dominican Republic, students from Jamaica (Adjusted Odds Ratio-AOR: 1.36, 95% confidence interval-CI: 1.01-1.85), students from Trinidad and Tobago (AOR: 1.46, 95% CI: 1.17-1.82) and male sex (AOR: 1.35, 95% CI: 1.11-1.64) were positively associated with meeting 3-4 ideal CVHB metrics. In addition, in unadjusted analysis, rarely or sometimes experiencing hunger was negatively and high peer and parent support were positively associated with meeting 3-4 ideal CVHB metrics. CONCLUSION: The proportion of meeting 3-4 ideal CVHB metrics was low among adolescents in four Caribbean countries. Both high-risk and school-wide intervention programmes should be implemented in aiding to improve CVHB in Caribbean countries. Several factors associated with ideal CVHB were identified, which can be targeted in school health interventions.

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.

ABSTRACT Objective: The number of palliative care patients in Trinidad and Tobago is unknown. The purpose of this study is to estimate the prevalence of palliative care patients on a public general medical ward. Methods: A retrospective cross-sectional study was undertaken to collect information on patients' diagnoses, symptoms and Palliative Performance Scale (PPS) scores. Patients who would benefit from palliative care services and satisfied inclusion criteria were referred to as palliative-care-appropriate patients. Results: The one-month prevalence of palliative-care-appropriate patients was found to be 23.47% on an acute medical ward of a public hospital. Most of these patients had diagnoses that were either neurologic or cardiac in nature. Pain (46.8%) and dyspnoea (51.1%) were the most common symptoms documented for palliative-care-appropriate patients. Seven (14.95%) palliative-care-appropriate patients died while in hospital. Conclusion: There is a significant palliative care burden in this pilot study as evidenced by the high prevalence of palliative-care-appropriate patients on a general medicine ward. A larger prospective study should be undertaken to elucidate the number of patients who could benefit from hospice and palliative care services. Palliative performance scale scores may be considered for more widespread use in the Caribbean.

ABSTRACT Objective: Screening for childhood obesity is a necessary step in developing appropriate and effective interventions. We evaluated the diagnostic performance of various recommended international anthropometric cut-offs based on body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), triceps skinfold (TSF), and mid-upper arm circumference (MUAC) in predicting excess adiposity (body fat ≥ 25%) in a random sample of Trinidadian preschoolers. Methods: After obtaining written parental consent, weight, height, WC, TSF, and MUAC were measured in 596 children using standard procedures. These were used to calculate BMI for age, WHtR, TSF-for-age z-scores, and MUAC-for-age z-scores. Percentage body fat was measured using a Tanita-531 foot-to-foot bioelectrical impedance analyser (BIA). Sensitivities, specificities and area under the receiver-operating curve analysis and predictive values were then computed in reference to BIA estimates. Results: The prevalence of excess adiposity was 12.2% and 5.1% among males and females, respectively. Sensitivities for the various cut-offs ranged from 20.0% to 75.0% and 57.1% to 96.9% among males and females, respectively. WHO-BMI recommended cut-offs and those based on MUAC z-scores had significantly higher sensitivities in females than in males. TSF z-scores had significantly lower sensitivities compared to those based on BMI and WHtR among males. Similarly, specificities ranged from 81.3% to 99.9% and 79.8% to 99.9% among males and females, respectively. In girls, cut-offs based on TSF z-scores had a higher likelihood ratio than cut-offs from Centers for Disease Control, International Obesity Task Force and WHtR. Diagnostic performance was not associated with ethnicity. Conclusion: Our results suggest that diagnostic performance was associated with gender and the cut-offs used; however, it was not associated with ethnicity.

BACKGROUND AND AIM: The coronavirus disease 2019 (COVID-19) pandemic has seen the cancellation of elective cardiac surgeries worldwide. Here we report the experience of a cardiac surgery unit in a developing country in response to the COVID-19 crisis. METHODS: From 6th April to 12th June 2020, 58 patients underwent urgent or emergency cardiac surgery. Data was reviewed from a prospectively entered unit-maintained cardiac surgery database. To ensure safe delivery of care to patients, a series of strict measures were implemented which included: a parallel healthcare system maintaining a COVID-19 cold site, social isolation of patients for one to 2 weeks before surgery, polymerase chain reaction testing for COVID-19, 72 hours before surgery, discrete staff assigned only to cardiac surgical cases socially isolated for 2 weeks as necessary. RESULTS: The mean age at surgery was 59.7 ± 11 years and 41 (70.7%) were male. Fifty-two patients were hypertensive (90%), and 32 were diabetic (55.2%). There were three emergency type A aortic dissections. Forty-seven patients underwent coronary artery bypass graft surgery with all but three performed off-pump. Fourteen cases required blood product transfusion. One patient had postoperative pneumonia associated with chronic obstructive pulmonary disease. The median length of stay was 5.7 ± 1.8 days. All patients were discharged home after rehabilitation. There were no cases of COVID-19 infection among healthcare workers during the study period. CONCLUSION: These strategies allowed us to maintain a service for urgent and emergency procedures and may prove useful for larger countries when there is decrease in COVID-19 cases and planning for the restart of elective cardiac surgery.

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.

Discus (Symphysodon spp.) are costly and prized specimens in the international ornamental fish trade. The majority of discus submitted to the Aquatic Animal Health Unit at the University of the West Indies School of Veterinary Medicine for necropsy between September 2010 and September 2015 had lesions consistent with Cryptobia iubilans infection, thus prompting this study. To determine the prevalence of the flagellated gastrointestinal protozoan C. iubilans in discus fish, 32 discus were sourced from 10 suppliers, including breeders, importers, and hobbyists across Trinidad. Fish were euthanized, and the internal organs, particularly the stomach and intestine, were observed under a light microscope for characteristic granulomatous lesions and/or live C. iubilans parasites. All wet-mount slides on which granulomas were observed were also Ziehl-Neelsen acid-fast stained to presumptively exclude the presence of Mycobacterium spp., the main differential when diagnosing C. iubilans-associated granulomatous gastritis or to determine the presence of dual infections. Further histological analyses were performed on stomach and intestinal sections, and transmission electron microscopy was used to confirm the parasite in stomach sections. The prevalence of C. iubilans infection was found to be 81.3%, and the prevalence of presumptive dual infections with Mycobacterium spp. was found to be 21.9%. To the best of our knowledge, this is the first documented study of C. iubilans infections in the wider Caribbean region.

BACKGROUND: Palliative care is in its infancy in most of the developing world. We set out to explore the lived experiences of families and caregivers of recently deceased cancer patients in Trinidad and Tobago and to determine the unmet needs of the patients and what recommendations could be derived to improve the current services. METHODS: A phenomenological approach with purposeful sampling was used. Participants were referred by key health professionals. Face-to-face interviews were conducted. Interviews were transcribed verbatim, with analysis and data collection occurring concurrently. Thematic content analysis was used to determine common domains, themes and sub-themes. RESULTS: Interviews were completed with 15 caregivers. All were spouses or children of the deceased. Ages of the deceased ranged from 43 to 93, the average being 65.5 years. The deceased experienced a variety of cancers including lung, colorectal and oesophageal. Unmet needs were identified under 4 domains of institutions, community, the family unit and the wider society. Institutional unmet needs were delayed diagnosis and treatment and poor inter-institution coordination. Medical and nursing care failed in the areas of health care providers' attitudes, pain management and communication. The family unit lacked physical and psychosocial support for the caregiver and financial aid for the family unit. Societal needs were for public education to address myths and cultural beliefs around cancer. CONCLUSION: There is need for systemic interventions to improve the care of those dying from cancer in Trinidad and Tobago. Stakeholders need to commit to palliative care as a public health priority, implementing education, planning services and mobilizing community resources.

Fowl adenovirus (FAdV), which causes the high-impact diseases such as inclusion body hepatitis and hepatitis-hydropericardium syndrome, is of major concern to the poultry industry internationally. This study was carried out in direct response to mortality rates of up to 75% in commercial broiler flocks in Trinidad, West Indies. Symptoms in 3- to 8-week-old broilers and 13- to 18-week-old pullets pointed to infection with an immunosuppressive viral pathogen. The objectives of the study were to determine whether the infectious agent FAdV, along with other viral pathogens, was responsible for the clinical disease, and to obtain information on the serotypes of FAdV that were infecting the birds. Tissue samples from clinically affected birds from eight different farms were tested for chicken infectious anaemia virus (CIAV) and infectious bursal disease virus (IBDV) by real-time reverse transcription polymerase chain reaction (PCR) and for FAdV by conventional PCR. The birds tested positive for FAdV and CIAV, but negative for IBDV. The gene corresponding to the L1 loop of the hexon protein for FAdV was amplified and sequenced. Phylogenetic analysis of seven FAdV strains inferred that four serotypes were likely to be circulating in the chickens. Well supported genetic relatedness was observed for serotype 8a (97.8%), 8b (97.8%), 9 (95.8%) and 11 (98.8%-99.5%). This is the first published report from Trinidad and Tobago on the presence and circulation of pathogenic FAdV strains, in combination with CIAV, in poultry. The data demonstrate a possible need for the introduction of serotype-specific vaccines against FAdV, as well as vaccines against CIAV, in broilers in the region and emphasize the importance of maintaining high levels of biosecurity on farms to prevent the spread of these potentially devastating viruses between farms.

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.

Objectives: Little is known about the oral health of paediatric oncology patients in the Caribbean. Poor oral health can complicate oncology treatment, negatively affecting a child's health. In children undergoing chemotherapy or bone marrow transplant, odontogenic infections can progress to life-threatening sepsis. The aim of this study is to investigate the oral health among children attending an oncology clinic in Trinidad. Material and Methods: Sample population included paediatric oncology patients attending a children's hospital in Trinidad. Subsequent to obtaining informed consent, a 14-item questionnaire was administered to parents/caregivers. An intra-oral examination was undertaken by two dentists to assess soft tissues, gingival health, and dentition status, using visual examination only. Results: Seventy-one children and their caregivers participated in the study. The children consisted of both patients warded or attending as outpatients; 53.5% of patients were male and the mean age 6.64 (SD 3.33) years with a range of 1 to 15 years. Gingivitis and mucositis were present among 41.3% and 3% of patients, respectively. The prevalence of visible dental caries was 54.3%. Caries experience (dmft) was 2.28 (SD 3.63), and for those children with some caries experience (dmft > 0), this was 5.59 (SD 3.72). The majority (62.5%) had never visited a dentist. The most common dental treatment needs were dental prophylaxis (98.4%) and restorative treatment (50.8%). Acute lymphocytic leukaemia (39.1%) was the most common malignancy among this sample, and patients were at varying stages of cancer treatment. Conclusions: Oral health among this sample of paediatric oncology patients was generally poor, with untreated caries being common, and the majority of children not having had any previous dental care. Preventive dental care for these patients should include oral hygiene instruction, dietary advice, topical fluoride application along with management of carious lesions, and odontogenic infections. This preliminary study highlights the need for closer collaboration between general dental practitioners, paediatric dentists, and paediatric oncology physicians, in caring for these patients.

ABSTRACT Objective: To compare all-cause-mortality in screening-detected prostate cancer cases versus non-cases after a median 12.2-year follow-up. Methods: In this prospective, population-based study of 3089 Afro-Caribbean men aged 40-79 years in Tobago, Trinidad and Tobago, West Indies, all men were screened for prostate cancer (serum prostate specific antigen and/or digital rectal exam) one to three times between 1997 and 2007 and followed for mortality to 2012. Among 502 men diagnosed with prostate cancer, 81 younger men underwent radical retropubic prostatectomy. Minimal treatment was available for older men. Survival curves compared all-cause-mortality in cases versus non-cases within 10-year age groups at first screening. Results: There were 350 all-cause-deaths over 34 089 person-years of follow-up. All-cause-survival curves in men aged 60 years or above at first screening did not diverge between cases and non-cases until after 10-12 years of follow-up (p > 0.36). In contrast, among men first screened at age 50-59 years, survival was lower in cases, with survival curves diverging at seven years (p = 0.003). Survival in men aged 50-59 years who underwent prostatectomy was similar to survival in non-cases (p = 0.63). Conclusion: Among men aged 60 years or above, the absence of excess all-cause-mortality among screening-detected prostate cancer cases provides argument against the utility of routine prostate cancer screening in this older population of African descent. However, the significantly poorer survival in men aged 50-59 years with screening-detected prostate cancer, compared with screened men without prostate cancer, along with the potential for prostate cancer treatment to improve survival, supports the continuation of prostate cancer screening in this age group, pending further research to assess the risks and benefits.
RESUMEN Objetivo: Comparar la mortalidad por todas las causas en casos de cáncer de próstata frente a no casos tras un seguimiento medio de 12.2 años. Métodos: En este estudio prospectivo poblacional de 3089 hombres afrocaribeños de 40-79 años en Tobago, Trinidad y Tobago, West Indies, todos los hombres fueron expuestos a tamizaje de cáncer de próstata (antígeno prostático específico en suero y/o examen rectal digital) de una a tres veces entre 1997 y 2007, y a un seguimiento de la mortalidad hasta 2012. De entre los 502 hombres diagnosticados con cáncer de próstata, a 81 hombres de los más jóvenes se les practicó una prostatectomía retropúbica radical. El tratamiento mínimo estuvo disponible para los hombres mayores. Las curvas de supervivencia compararon la mortalidad por todas las causas en los casos frente a los no casos dentro de los grupos de edades de 10 años en la primera tamización. Resultados: Hubo 350 muertes por todas las causas con más de 34 089 persona-años de seguimiento. Las curvas de supervivencia por todas las causas en hombres de 60 años o más en el primer tamizaje, no divergieron entre casos y no casos hasta después de 10 a 12 años de seguimiento (p > 0.36). En cambio, entre los hombres tamizados por primera vez a la edad 50-59 años, la supervivencia fue menor en los casos, con curvas de supervivencia divergentes a los siete años (p = 0.003). La supervivencia en los hombres de 50-59 años que tuvieron prostatectomía fue similar a la supervivencia en los no casos (p = 0.63). Conclusión: Entre los hombres de 60 años o más, la ausencia de exceso de mortalidad por todas las causas entre los casos de cáncer de próstata detectados por tamizaje proporciona argumentos contra la utilidad de la tamización rutinaria del cáncer de próstata en esta población mayor de ascendencia africana. Sin embargo, la supervivencia significativamente más pobre en hombres de 50 a 59 años con cáncer de próstata detectado mediante tamizaje - en comparación con los hombres tamizados sin cáncer de próstata, además de las posibilidades de tratamiento del cáncer de próstata para mejorar la supervivencia - respalda la continuación del tamizaje del cáncer de próstata en este grupo etario, quedando pendiente una investigación ulterior a fin de evaluar sus riesgos y beneficios.

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.
