RESUMEN

Objective: To compare the adequacy, agreement, and acceptability of Papanicolaou testing (cytology) for cervical cancer screening using self-collected samples compared to physician-collected samples in Grenada in the Caribbean. Furthermore, the study identifies the human papillomavirus (HPV) genotypes present among asymptomatic women testing positive for HPV, the etiologic cause of cervical cancer. Methods: Participants were divided into two groups and two cervical samples were collected from the women in each group: a self-collected sample and a physician-collected sample. Cervical specimens were tested for cytology and HPV. HPV genotyping was performed on positive specimens. Results: Self-collected samples were adequate and in agreement with physician-collected samples, showing no difference between the two sampling methods. Oncogenic high-risk HPV genotypes were identified in cervical samples which were positive for atypical squamous cells and low-grade squamous intraepithelial lesions. The high-risk HPV genotypes found, notably HPV 45 and 53, differed from those most commonly reported. Although the commonly reported high-risk genotypes HPV 16 and 18 were found, so were 31, 33, 35, 52, 66, 68, and 82. Conclusions: Using self-collection facilitated the discovery of unexpected HPV genotypes among asymptomatic women in Grenada. These findings add new information to the literature regarding cervical cancer and neoplasia screening and HPV genotypes in the Caribbean. This genotype information may impact surveillance of women with low-grade lesions, HPV vaccine selection, and possibly further vaccine research. Research regarding HPV in Caribbean pathology samples of cervical neoplasia and cancer is needed.

RESUMEN

Sarcocystis miescheriana infection is an important cause of carcass condemnation during meat inspection. The infection can cause morbidity and mortality in domestic pigs. In this study, an 8-month-old finisher pig was presented to a local abattoir for slaughter. Multiple white nodular lesions affecting the meat were observed, resulting in the condemnation of the carcass. Consequently, half of the carcass was submitted to the necropsy diagnostic laboratory in the School of Veterinary Medicine for further evaluation. Grossly, all superficial and deep muscle groups had severe multifocal macrocysts (3 mm × 2 mm × 1 mm) on the surface and extending deep into the skeletal musculature. Histopathology revealed moderate multifocal granulomatous and eosinophilic myositis with intralesional degenerated and intact parasites. Sample genomic DNA sequence analysis of the 18S RNA gene showed 100% identity to S. miescheriana in the GenBank. This is the first report of S. miescheriana in Grenada, West Indies.

RESUMEN

Oestrosis is a nasal cavity myiasis caused by Oestrus ovis larvae from Oetrus ovis diptera flies in small ruminants. The presence of the larvae in the nasal cavity is known to cause rhinitis and sinusitis which can negatively impact the productivity of small ruminants. The aim of the present study was to estimate the prevalence of Oestrus ovis larvae infestation in sheep and goats presented for necropsy. We reviewed necropsy records of sheep and goats submitted to the Veterinary Pathology diagnostic laboratory at St. George's University from 2001 to 2017. Out of 104 goat necropsy cases, Oestrus ovis larvae were observed in 8 goats giving a prevalence of 7.7% (95% confidence interval (CI):3.38% to 14.6%). Similarly, from the 47 sheep necropsies, Oestus ovis larvae were observed in 4 sheep (8.5%) (95% CI: 2.83% to 20.46%). There was no significant difference in Oestrus ovis larvae infestation rates between sheep and goats (p = 1.000, Fisher's exact test). Oestrosis was an incidental finding in all the small ruminants examined at necropsy. This is the first report on Oestrus ovis larvae infestation in small ruminants in Grenada.

RESUMEN Objetivo. Comparar la idoneidad, concordancia y aceptabilidad de la prueba de Papanicolaou (citología) para el tamizaje del cáncer cervicouterino mediante la comparación de muestras obtenidas con automuestreo y muestras tomadas por personal médico en Granada, en el Caribe. Asimismo, en el estudio se identifican los genotipos del virus del papiloma humano (VPH) existentes en las mujeres asintomáticas con un resultado positivo en las pruebas del VPH, la causa etiológica del cáncer cervicouterino. Métodos. Las participantes se dividieron en dos grupos y se tomaron dos muestras cervicouterinas de las mujeres de cada grupo: una muestra tomada por la propia paciente y una muestra tomada por personal médico. Se realizó un examen citológico y una prueba de detección del VPH en las muestras. En las muestras positivas, se determinó el genotipo del VPH. Resultados. Las muestras tomadas por las propias pacientes fueron adecuadas y concordaron con las obtenidas por el personal médico, sin que se observaran diferencias entre ambos métodos de muestreo. Se identificaron genotipos de VPH de alto riesgo oncogénico en muestras cervicouterinas positivas para células escamosas atípicas y lesiones intraepiteliales escamosas de grado bajo. Los genotipos de VPH de alto riesgo encontrados, en especial VPH 45 y 53, diferían de los notificados con mayor frecuencia. Aunque se encontraron los genotipos de alto riesgo habituales 16 y 18 del VPH, también se encontraron los genotipos 31, 33, 35, 52, 66, 68 y 82. Conclusiones. El uso del automuestreo facilitó la detección de genotipos inesperados del VPH en mujeres asintomáticas de Granada. Estos resultados agregan nueva información a la bibliografía sobre el tamizaje de las neoplasias y el cáncer cervicouterino, así como sobre los genotipos del VPH, en el Caribe. Esta información sobre el genotipo puede repercutir en la vigilancia de las mujeres con lesiones de bajo grado, en la elección de la vacuna contra el VPH y, posiblemente, en las ulteriores investigaciones sobre vacunas. Es necesario investigar la presencia del VPH en muestras anatomopatológicas de neoplasias y cánceres cervicouterinos en el Caribe.


RESUMO Objetivo. Comparar a adequação, o nível de concordância e a aceitabilidade do exame de Papanicolau (citologia) para o rastreamento do câncer do colo do útero usando amostras autocoletadas em comparação com amostras coletadas por médicos em Granada, no Caribe. Além disso, o estudo identifica os genótipos de papilomavírus humano (HPV) presentes entre as mulheres assintomáticas com resultado positivo para HPV, a causa etiológica do câncer do colo do útero. Métodos. As participantes foram divididas em dois grupos, e duas amostras cervicais foram coletadas das mulheres de cada grupo: uma amostra autocoletada e uma amostra coletada por um médico. As amostras cervicais foram submetidas a exames citológicos e de HPV. A genotipagem do HPV foi realizada nas amostras positivas. Resultados. As amostras autocoletadas eram adequadas e compatíveis com as amostras coletadas por médicos, não havendo diferença entre os dois métodos de amostragem. Foram identificados genótipos de HPV de alto risco oncogênico em amostras cervicais positivas para células escamosas atípicas e lesões intraepiteliais escamosas de baixo grau. Os genótipos de HPV de alto risco encontrados, principalmente HPV 45 e 53, não correspondiam aos genótipos registrados com mais frequência na literatura. Embora os genótipos de alto risco HPV 16 e 18, que são frequentemente registrados, tenham sido observados, também foram detectados os genótipos 31, 33, 35, 52, 66, 68 e 82. Conclusões. O uso da autocoleta facilitou a detecção de genótipos inesperados de HPV entre mulheres assintomáticas em Granada. Esses achados adicionaram novas informações à literatura sobre o rastreamento de neoplasias e câncer do colo do útero e sobre os genótipos de HPV no Caribe. Essas informações genotípicas podem afetar a vigilância de mulheres com lesões de baixo grau, a seleção da vacina contra o HPV e, possivelmente, futuras pesquisas sobre vacinas. É necessário pesquisar o HPV em amostras patológicas de neoplasias cervicais e câncer do colo do útero no Caribe.

RESUMEN

As an island endemic with a decreasing population, the critically endangered Grenada Dove Leptotila wellsi is threatened by accelerated loss of genetic diversity resulting from ongoing habitat fragmentation. Small, threatened populations are difficult to sample directly but advances in molecular methods mean that non-invasive samples can be used. We performed the first assessment of genetic diversity of populations of Grenada Dove by (a) assessing mtDNA genetic diversity in the only two areas of occupancy on Grenada, (b) defining the number of haplotypes present at each site and (c) evaluating evidence of isolation between sites. We used non-invasively collected samples from two locations: Mt Hartman (n = 18) and Perseverance (n = 12). DNA extraction and PCR were used to amplify 1751 bps of mtDNA from two mitochondrial markers: NADH dehydrogenase 2 (ND2) and Cytochrome b (Cyt b). Haplotype diversity (h) of 0.4, a nucleotide diversity (π) of 0.00023 and two unique haplotypes were identified within the ND2 sequences; a single haplotype was identified within the Cyt b sequences. Of the two haplotypes identified, the most common haplotype (haplotype A = 73.9%) was observed at both sites and the other (haplotype B = 26.1%) was unique to Perseverance. Our results show low mitochondrial genetic diversity and clear evidence for genetically isolated populations. The Grenada Dove needs urgent conservation action, including habitat protection and potentially augmentation of gene flow by translocation in order to increase genetic resilience and diversity with the ultimate aim of securing the long-term survival of this critically endangered species.

RESUMEN

Objectives: To identify the factors contributing to coronavirus disease 2019 (COVID-19) vaccine hesitancy in Grenada. Methods: A phenomenological study was conducted using semi-structured interviews at vaccination and pop-up testing clinics during a spike in COVID-19 cases on the island. Interview questions were developed using the health belief model related to perceived threat of COVID-19, perceived benefits of and barriers to COVID-19 vaccination, and cues to action. Data were analyzed using a deductive approach to identify themes, categories, and subcategories. Results: Twenty-five interviews were transcribed and coded. In all, 68% of participants were unvaccinated, 12% were partially vaccinated, and 20% were fully vaccinated. Data analysis revealed two main themes: facilitators and barriers. Factors more likely to encourage vaccination (facilitators) included trust in medical advice and vaccine efficacy, social responsibility, and vaccine mandates for travel, employment, and social activities. Factors hindering vaccination (barriers) included: perceived low threat of COVID-19; preference for natural remedies; concerns about contraindications because of underlying health conditions; fear; mistrust of vaccines and related messaging; vaccine accessibility; and the many different information sources. Conclusions: Overcoming vaccine hesitancy is key to combating the detrimental effects of COVID-19 in Grenada. Public health interventions and policies that address barriers and capitalize on facilitators can increase vaccine uptake.

RESUMEN

Objective: To document Grenadian women's knowledge about cervical cancer and human papillomavirus (HPV) infection, as well as their attitudes towards primary cervical cancer screening methods. Methods: In this qualitative study, we used focus groups in Grenada to gather information concerning women's knowledge about, attitudes towards and perceptions of screening for cervical cancer and general knowledge about HPV. Ten focus groups comprising 73 participants representing 5 of the 6 parishes in Grenada were conducted with women aged 19-59. Participants were asked about pelvic exams, Pap smears, HPV, reasons for seeking or avoiding cervical cancer screening and how different modalities of testing might affect their decision-making. Responses were then coded and organized into common themes. Results: While many respondents had heard of HPV, far fewer knew about its causative role in cervical cancer, how to prevent HPV infection or testing for the high-risk HPV types that cause almost all cases of cervical cancer. Many participants were aware that cervical cancer screening was beneficial, but numerous barriers to obtaining that screening were noted, including concerns about privacy and stigma, potential discomfort, and the cost and inconvenience involved. Conclusions: Our findings have implications for future cervical cancer screening efforts in Grenada. Central to these efforts should be a focus on educating Grenadians about the role of HPV infection in cervical cancer and the importance of early detection through screening. In addition, addressing issues of stigma and privacy are key to eliminating cervical cancer in Grenada.

RESUMEN Objetivos. Determinar cuáles son los factores que contribuyen con la reticencia a la vacunación contra la enfermedad por el coronavirus del 2019 (COVID-19) en Granada. Métodos. Se realizó un estudio fenomenológico utilizando entrevistas semiestructuradas realizadas en puestos transitorios de prueba y vacunación durante un aumento en el número de casos de COVID-19 en la isla. Se elaboraron las preguntas de la entrevista según el modelo de creencias de salud en relación con la amenaza percibida respecto de la COVID-19, los obstáculos y los beneficios percibidos respecto de la vacunación contra la COVID-19 y los incentivos para la acción. Los datos se analizaron mediante un enfoque deductivo con el fin de determinar los principales temas, categorías y subcategorías. Resultados. Se transcribieron y codificaron veinticinco entrevistas. En total, el 68% de los participantes no estaban vacunados, el 12% estaban parcialmente vacunados y el 20% tenían el esquema completo de vacunación. El análisis de los datos reveló dos temas principales: los factores facilitadores y los obstáculos. Entre los factores con mayores probabilidades de incentivar la vacunación (factores facilitadores) se encuentran la confianza en el asesoramiento médico y la eficacia de la vacuna, la responsabilidad social y los mandatos de vacunación para viajes, empleo y actividades sociales. Entre los factores que obstaculizan la vacunación (obstáculos) se encuentran la percepción de que la COVID-19 no es una amenaza grave; la preferencia por los remedios naturales; las preocupaciones por las contraindicaciones debido a afecciones de salud subyacentes; el miedo; la desconfianza en las vacunas y los mensajes relacionados; la accesibilidad a las vacunas; y las muy diferentes fuentes de información. Conclusiones. Es necesario superar la reticencia a la vacunación para combatir los efectos nocivos de la COVID-19 en Granada. Las políticas e intervenciones de salud pública que abordan los obstáculos y capitalizan los factores facilitadores pueden aumentar el uso efectivo de las vacunas.


RESUMO Objetivos. Identificar os fatores que contribuem para a hesitação em relação à vacina contra a doença por coronavírus 2019 (covid-19) em Granada. Métodos. Realizou-se um estudo fenomenológico com entrevistas semiestruturadas em clínicas de vacinação e testagem rápida durante um pico de casos de covid-19 na ilha. As perguntas da entrevista foram elaboradas com base no modelo de crenças em saúde relacionado à percepção de ameaça da covid-19, à percepção de benefícios e barreiras relativos à vacinação contra a covid-19, e aos estímulos para ação. Os dados foram analisados por um método dedutivo para identificar temas, categorias e subcategorias. Resultados. Vinte e cinco entrevistas foram transcritas e codificadas. No total, 68% dos participantes não eram vacinados, 12% eram parcialmente vacinados e 20% eram totalmente vacinados. A análise dos dados evidenciou dois temas principais: facilitadores e barreiras. Os fatores mais propensos a incentivar a vacinação (facilitadores) foram confiança na orientação médica e na eficácia da vacina, responsabilidade social e exigência de vacinação em viagens, no emprego e em atividades sociais. Entre os fatores que impediam a vacinação (barreiras) estavam: percepção de baixa ameaça da covid-19; preferência por remédios naturais; preocupação com contraindicações em razão de problemas de saúde preexistentes; medo; desconfiança das vacinas e mensagens relacionadas; acessibilidade da vacina; e as muitas diferentes fontes de informação. Conclusões. Superar a hesitação vacinal é imprescindível para combater as consequências negativas da covid-19 em Granada. As intervenções e políticas de saúde pública que afastam barreiras e promovem facilitadores podem aumentar a aceitação da vacina.

RESUMEN Objetivo. Documentar los conocimientos de las mujeres granadinas sobre el cáncer cervicouterino y la infección por el virus de los papilomas humanos (VPH), así como sus actitudes hacia los métodos primarios de detección del cáncer cervicouterino. Métodos. En este estudio cualitativo, se han empleado grupos focales en Granada para recopilar información sobre los conocimientos, las actitudes y las percepciones de las mujeres sobre la detección del cáncer cervicouterino y nociones generales sobre el VPH. Participaron 73 mujeres de 19 a 59 años de edad, representantes de 5 de las 6 parroquias de Granada. Se formaron diez grupos focales, a los que se les preguntó sobre los exámenes pélvicos, las pruebas de Papanicolaou, el VPH, las razones para buscar o evitar la detección del cáncer cervicouterino y cómo las diferentes modalidades de examen podrían afectar sus decisiones. Luego se codificaron las respuestas y se organizaron en temas comunes. Resultados. Si bien muchas participantes habían oído hablar del VPH, un número considerablemente menor conocía su relación causal con el cáncer cervicouterino, cómo prevenir la infección por VPH o los exámenes de detección de los tipos del VPH de alto riesgo que causan casi todos los casos de cáncer cervicouterino. Muchas participantes sabían que los exámenes de detección del cáncer de cuello uterino eran convenientes, pero mencionaron numerosos obstáculos para obtenerlos, como las preocupaciones sobre la privacidad y la estigmatización, posibles molestias, así como el costo y los inconvenientes relacionados. Conclusiones. Nuestros hallazgos tienen implicaciones para la futura labor de detección del cáncer cervicouterino en Granada. En esta labor debería ser esencial adoptar un enfoque dirigido a educar a las granadinas sobre la relación de la infección por VPH con el cáncer cervicouterino y la importancia de la detección temprana mediante exámenes. Además, combatir los problemas de estigmatización y privacidad es clave para eliminar el cáncer cervicouterino en Granada.


RESUMO Objetivo. Documentar o conhecimento das mulheres de Granada sobre o câncer do colo do útero e a infecção por papilomavírus humano (HPV), bem como suas atitudes em relação aos métodos de rastreamento de câncer do colo do útero primário. Métodos. Neste estudo qualitativo, usamos grupos focais em Granada para coletar informações sobre conhecimentos, atitudes e percepções das mulheres sobre o rastreamento de câncer do colo do útero e conhecimentos gerais sobre HPV. Foram conduzidos dez grupos focais, incluindo 73 participantes e representando 5 das 6 paróquias de Granada, com mulheres de 19 a 59 anos de idade. As participantes responderam perguntas sobre exames ginecológicos, Papanicolau, HPV, razões para procurar ou evitar o rastreamento de câncer do colo do útero e como diferentes modalidades de testes podem afetar sua tomada de decisão. As respostas foram codificadas e organizadas por temas comuns. Resultados. Muitas participantes já tinham ouvido falar do HPV, mas um número muito menor conhecia sua relação causal com o câncer do colo do útero, formas de prevenir a infecção por HPV ou os testes para os tipos de HPV de alto risco, que causam quase todos os casos de câncer do colo do útero. Muitas participantes sabiam que o rastreamento de câncer do colo do útero era benéfico, mas várias barreiras para o rastreamento foram indicadas, incluindo preocupações relacionadas à privacidade e ao estigma, o potencial desconforto e o custo e inconveniência envolvidos. Conclusões. Nossos achados têm implicações para as futuras iniciativas de rastreamento de câncer do colo do útero em Granada. Essas iniciativas devem se focar em educar a população de Granada sobre o papel da infecção por HPV no câncer do colo do útero e a importância da detecção precoce por meio do rastreamento. Além disso, é fundamental abordar questões de estigma e privacidade para eliminar o câncer do colo do útero em Granada.

RESUMEN

Ancylostoma ceylanicum hookworms are recognized agents of human infection in the Asia-Pacific region. We investigated prevalence of zoonotic hookworm infections in dogs in Grenada in 2021; 40.8% were infected by hookworms, including Ancylostoma ceylanicum. Surveillance of this parasite in dogs and humans is needed in tropical/subtropical countries in the Americas.

RESUMEN

BACKGROUND: Toxoplasma gondii is a widespread zoonotic protozoan parasite capable of infecting all warm-blooded animals. Although the genotypes of T. gondii in pigs have been reported worldwide, there is no information on the genotypes and diversity of T. gondii in pigs in Grenada, West Indies. OBJECTIVES: The aims of the present study were to isolate, genotype and determine the diversity of T. gondii genotypes in pigs. METHODS: We carried out a modified agglutination test (MAT) on blood from 149 pig hearts collected from a local meat market. Myocardial tissue homogenate from pigs that tested positive for T. gondii was homogenized and inoculated into mice for isolation of the parasite. We collected mouse tissues and extracted DNA for genotyping based on 11 polymerase chain reaction-restriction fragment length polymorphism markers (SAG1, SAG2, alt. SAG2, SAG 3, BTUB, GRA6, L358, PK1, C22-8, C 29-2 and Apico). RESULTS: Out of the 149 pig hearts, 31 (20.8%) tested positive for T. gondii on MAT. Bioassays in mice yielded 12 isolates designated TgpgGr1 to TgpgGr12. Molecular characterisation of T. gondii revealed four genotypes as follows: ToxoDB #2-clonal type III (seven isolates); ToxoDB #7 (three isolates); ToxoDB #13 (one isolate); ToxoDB #30 (1 isolate). Overall, ToxoDB #2 was the most common (58%). Toxo database (DB) # 13, which causes interstitial pneumonia in affected mice, has also been reported. CONCLUSION: The genetic diversity of T. gondii in pigs in Grenada is lower than that in other surrounding Caribbean areas.

RESUMEN

BACKGROUND: Canine transmissible venereal tumour (CTVT) is a naturally occurring neoplasia affecting dogs worldwide. Previous CTVT studies in Grenada were limited to case records of dogs with neoplastic conditions at a veterinary diagnostic laboratory. OBJECTIVES: The present retrospective study aimed to determine the occurrence and risk factors of CTVT in a wider population of owned dogs presented to a university-affiliated veterinary hospital between 2008 and 2018. METHODS: Data on the age, breed, gender, and gonadectomy status were retrieved from an electronic database and analyzed using logistic regression. RESULTS: Of the 7180 dogs presented during the period, 102 dogs (1.4%) were diagnosed with CTVT. A higher predisposition was observed in Grenadian pothounds (odds ratio [OR] = 22.8, 95% confidence interval [CI] 10.3-50.4; p < 0.001) and mixed-breed dogs (OR = 9.2, 95% CI 4.1-20.7; p < 0.001) in comparison to the purebreds. Neutered dogs (OR = 2.2, 95% CI 1.4-3.3; p < 0.001) were at an increased risk of CTVT than intact dogs. Age and gender were not identified as significant risk factors. CONCLUSIONS: The percentage of dogs with CTVT in this study represents a crude estimate of the CTVT prevalence in the owned dog population in Grenada. Further studies including both owned and free-roaming dogs are required for a more accurate estimation of the CTVT prevalence in the region. Our results indicate that breed and gonadectomy status are significant risk factors for the occurrence of CTVT in Grenada.

RESUMEN

Objective: The aim of this study was to evaluate the impact of Woman- to-Woman, a lay health advisor (LHA)-led educational intervention on cervical cancer and human papillomavirus (HPV) knowledge in a cohort of at-risk Grenadian women. Methods: LHAs from high-risk parishes were trained in the administration of the intervention and administered the program to 78 local women. Participants completed a pre- and post-knowledge test and a session evaluation. LHAs participated in a process evaluation focus group. Results: Sixty-eight percent (68%) of participants obtained higher knowledge scores following the educational intervention. The difference between the pre- and post-test scores was statistically significant (p = 0.05). Almost 94% agreed that they were taught new and useful information by credible, community informed and responsive LHAs. Ninety percent (90%) indicated great satisfaction and high motivation to recommend to others. LHAs reported on the intervention and their community interactions. Conclusions: Results demonstrate that a LHA-led educational intervention significantly improved participants' knowledge of cervical cancer, HPV, Papanicolaou test and vaccination against HPV. Innovations: Researchers trancreated an evidenced based intervention originally designed for Latina women for Grenadian women. There is no evidence in the literature of previous LHA- cervical cancer education studies conducted in Grenada nor the Caribbean.

RESUMEN

The hawksbill turtle Eretmochelys imbricata is a critically endangered species with a worldwide distribution. Limited information is available about the naturally occurring intestinal parasites of this species and what impact these parasites may have on the health of the hawksbill turtle. Diaschistorchis pandus was identified postmortem in 5 hawksbill turtles from Grenada, West Indies, using morphologic characterization. Sanger sequencing was performed for conserved ribosomal regions (5.8S, ITS2, 28S) and the mitochondrial cytochrome c oxidase subunit 1 gene (COI). Phylogenetic analysis of the 28S rRNA gene sequence data shows D. pandus clustering with other trematodes in the family Pronocephalidae, corroborating morphological classification. No genetic sequences have been previously reported for this trematode species, which has limited the collection of objective epidemiological data about this parasite of marine turtles.

RESUMEN

BACKGROUND: Grenada is a small, resource-limited Caribbean country with a high incidence of sickle cell disease (SCD). Since little is known about the challenges facing individuals living with SCD in the West Indies, we sought to assess barriers to healthcare and the impact of SCD on quality of life in Grenada. METHODS: Both adults aged 18+ (n = 19) and caregivers of children aged 2-17 (n = 26) completed validated survey measures regarding barriers to care and quality of life, along with a genetics knowledge questionnaire. Caregivers also completed a caregiver burden scale. Survey scores were calculated, and responses were analyzed for an association between demographic variables. RESULTS: The Barriers to Care Questionnaire, in which lower scores indicate more barriers, revealed that both adults (mean = 69.9) and children (mean = 75.5) with SCD experienced reduced access to care. The Adult Sickle Cell Quality of Life Measurement Information System indicated increased depression and loneliness in adults, with the lowest scores in the Emotional subscale. However, the Pediatric Quality of Life Inventory answered by caregivers of children with SCD showed the lowest scores in the Physical Functioning subscale. Further analysis using the Caregiver Burden Scale-Zarit Burden Interview revealed that 53.8% of caregivers of children with SCD indicated "little to no burden," which may reflect a difference in cultural expectations of a caregiver between high-income countries and Grenada. Finally, ~80% of respondents knew that SCD was a genetic condition; however, 61%-84% could not correctly indicate recurrence risks, demonstrating a need for additional education. CONCLUSION: These data provide new insights regarding the experience of living with SCD in Grenada and support the need for further investigations into specific barriers to healthcare delivery, which could also improve education and well-being for those affected by SCD in Grenada and in the broader Caribbean community.

RESUMEN

ABSTRACT: In scombroid poisoning, a seafood-associated disease, consumption of fish that contains high levels of histamine results in allergy-like symptoms that range from mild to occasionally severe. To date, there is no published information on scombroid poisoning from Selar crumenophthalmus on the Caribbean island of Grenada, West Indies. S. crumenophthalmus is of particular interest because it is a common and heavily consumed fish that has been implicated in scombroid poisoning in Hawaii. Preliminary data on S. crumenophthalmus in Grenada have demonstrated the presence of Photobacterium damselae, a bacterium associated with scombroid poisoning. The present study further tested S. crumenophthalmus purchased in Grenada for factors that would indicate the potential for scombroid poisoning, including increased histamine levels in fish muscle and DNA evidence of bacteria associated with scombroid poisoning. Histamine levels between 7,160 and 66,688 ppm were found after temperature abuse at 37°C for 19 h; this far exceeds the acceptable limit for the United States (50 ppm) and the European Union (100 to 200 ppm). Even after 4 h of incubation at ambient temperature (28.9°C) during a time-point study, histamine levels exceeded U.S. acceptable limits (>50 ppm), and five samples used for temperature-abuse studies had elevated histamine levels (ranging from 141 to 2,510 ppm) at 0 h. PCR and sequence analysis of bacteria in temperature-abused fish identified P. damselae and Morganella morganii, which are histamine-producing bacteria known to be implicated in scombroid poisoning. These results suggest the potential for scombroid poisoning in Grenada and the need for promoting awareness about this disease.

RESUMEN

If high-conflict family environments are cariogenic across cultures, and can be studied in cultures where both these environments and cariogenic dental practices are particularly prevalent, this would afford the opportunity to examine how these two pathways of risk might interact, laying the stage for culturally competent, integrated prevention efforts. The first investigation involved qualitative data about perceptions of oral health and family stressors in Grenadian families with school-aged children. The second study used a questionnaire and observational data to assess relations among oral health behaviors, relationship satisfaction, parenting, and child behavior; it also included a pilot study of Motivational Interviewing. Most of the themes discussed in focus groups suggested overlap between U.S. and Grenadian parents; possible culture-specific issues were high prevalence of single-parent homes, normativity of physical discipline, less preventive dental care, and more fatalistic view of oral health outcomes. Significant associations were found between parent and child oral health behaviors, between child externalizing and internalizing behaviors, and between family variables (e.g., relationship satisfaction, child behavior) and oral health behaviors (e.g., parent flossing, child brush time). The results strongly support the need for research on the relations between family functioning and oral health to be embedded within culture.

RESUMEN

This study identifies the endoparasites in Red-footed tortoises (Chelonoidis carbonaria) during March 2018 to March 2019 from Grenada, West Indies. Fecal samples from a total of 103 tortoises were collected and examined by simple fecal floatation techniques for parasitic eggs and oocysts. Adult parasites found in the feces were examined under the microscope for identification based on their morphology. Fecal samples for this research were collected from four parishes; St. Andrew, St George, St. John and St. Patrick. The overall prevalence of intestinal parasites among tortoises was 14.6%. The internal parasites consisted of nematodes belonging to three genera: Atractis, Labiduris and Proatractis. The most prevalent nematodes were Atractis spp. (86.7%), which included two species: A. thapari (7.7%) and A. marquezi (15.4%) followed by Labiduris gulosa (20%) and Proatractis parvicapiticaronata (13.3%). All nematodes of three genera found in red-footed tortoises in Grenada are reported for the first time. They are not zoonotic but are serious pathogens for tortoises.

RESUMEN

Philornis flies Meinert (Diptera: Muscidae) have been documented parasitizing over 250 bird species, some of which are endemic species threatened with extinction. Philornis parasitism is hypothesized to affect nestlings disproportionately more than adult birds because limited mobility and exposed skin of nestlings increase their vulnerability to parasitism. We used a comprehensive literature review and our recent fieldwork in the Dominican Republic, Puerto Rico, and Grenada to challenge the idea that parasitism by subcutaneous Philornis species is a phenomenon primarily found in nestlings, a fact that has not been quantified to date. Of the 265 reviewed publications, 125 (49%) reported incidences of parasitism by subcutaneous Philornis, but only 12 included the sampling of adult breeding birds. Nine of these publications (75%) reported Philornis parasitism in adults of ten bird species. During fieldwork in the Dominican Republic, Puerto Rico, and Grenada, we documented 14 instances of parasitism of adult birds of seven avian species. From literature review and fieldwork, adults of at least fifteen bird species across 12 families and four orders of birds were parasitized by at least five Philornis species. In both the published literature and fieldwork, incidences of parasitism of adult birds occurred predominantly in females and was frequently associated with incubation. Although our findings indicate that Philornis parasitism of adult birds is more common than widely presumed, parasite prevalence is still greater in nestlings. In the future, we recommend surveys of adult birds to better understand host-Philornis relationships across life stages. This information may be essential for the development of effective control measures of Philornis to ensure the long-term protection of bird species of conservation concern.
