Surgery for Craniosynostosis: Developing a Psychosocial Booklet for Families.

Parents of children with craniosynostosis may experience psychological distress, particularly during intensive periods of treatment. Yet, recent research indicates parents may not be accessing the support they need to cope with common challenges. The aim was to develop an evidence-based booklet to promote psychological health in families undergoing surgery and to assess the acceptability of the booklet among the craniosynostosis community. Researchers collaborated with UK charity Headlines Craniofacial Support, 5 parent representatives, and 2 specialist clinical psychologists to develop the booklet based on data obtained from online focus groups, individual interviews, and written accounts. The draft booklet was attached to an online acceptability survey and distributed to a broader group of parents and multidisciplinary craniofacial specialists for feedback. A total of 52 complete responses to the online acceptability survey were received, and acceptability (measured by the number of respondents who would recommend the booklet) was 100%. All respondents supported the UK-wide distribution of the booklet. Evidence for psychological intervention in the craniofacial field remains scarce, and specialist teams may be under-resourced to effectively screen and support families. It is hoped this booklet can begin to address the gap in psychological support for families affected by craniosynostosis.

"When I was Younger, My Story Belonged to Everyone Else": Co-production of Resources for Adults Living with Craniosynostosis.

OBJECTIVE: Despite growing recognition that congenital craniofacial conditions have lifelong implications, psychological support for adults is currently lacking. The aim of this project was to produce a series of short films about living with craniosynostosis in adulthood, alongside a psychoeducational booklet. DESIGN: The resources were developed using multiple focus groups and meetings attended by researchers, patient representatives, a leading charitable organisation, an award-winning film production company, clinicians, and other experts in the field. RESULTS: An online mixed-methods survey was developed based on prior work to request feedback on the acceptability and utility of the resources from the craniosynostosis community. While data collection to evaluate the resources is ongoing, preliminary results (n = 36) highlight an acceptability rating of 100%. CONCLUSIONS: The resources developed represent a step forward in addressing the unmet information and support needs of adults with craniosynostosis and highlight the benefits of co-production in research.

Preparation and Imaging of Specialized ER Using Super-Resolution and TEM Techniques.

The plant endoplasmic reticulum (ER) forms several specialized structures. These include the sieve element reticulum (SER) and the desmotubule formed as the ER passes through plasmodesmata. Imaging both of these structures has been inhibited by the resolution limits of light microscopy and their relatively inaccessible locations, combined with the fragile nature of the ER. Here we describe methods to view desmotubules in live cells under 3D-structured illumination microscopy (3D-SIM) and methods to fix and prepare phloem tissue for both 3D-SIM and transmission electron microscopy (TEM), which preserve the fragile structure and allow the detailed imaging of the SER.

Environmental DNA methods for biosecurity and invasion biology in terrestrial ecosystems: Progress, pitfalls, and prospects.

Analysis of environmental DNA (eDNA) enables indirect detection of species without the need to directly observe and sample them. For biosecurity and invasion biology, eDNA-based methods are useful to address biological invasions at all phases, from detecting arrivals to confirming eradication of past invasions. We conducted a systematic review of the literature and found that in biosecurity and invasion biology, eDNA has primarily been used to detect new incursions and monitor spread in marine and freshwater ecosystems, with much slower uptake in terrestrial ecosystems, reflecting a broader trend common to the usage of eDNA tools. In terrestrial ecosystems, eDNA research has mostly focussed on the use of eDNA metabarcoding to characterise biodiversity, rather than targeting biosecurity threats or non-native populations. We discuss how eDNA-based methods are being applied to terrestrial ecosystems for biosecurity and managing non-native populations at each phase of the invasion continuum: transport, introduction, establishment, and spread; across different management options: containment, control, and eradication; and for detecting the impact of non-native organisms. Finally, we address some of the current technical issues and caveats of eDNA-based methods, particularly for terrestrial ecosystems, and how these might be solved. As eDNA-based methods improve, they will play an increasingly important role in the early detection and adaptive management of biological invasions, and the implementation of effective biosecurity controls.

Biological effects of sodium phenylbutyrate and taurursodiol in Alzheimer's disease.

INTRODUCTION: Sodium phenylbutyrate and taurursodiol (PB and TURSO) is hypothesized to mitigate endoplasmic reticulum stress and mitochondrial dysfunction, two of many mechanisms implicated in Alzheimer's disease (AD) pathophysiology. METHODS: The first-in-indication phase 2a PEGASUS trial was designed to gain insight into PB and TURSO effects on mechanistic targets of engagement and disease biology in AD. The primary clinical efficacy outcome was a global statistical test combining three endpoints relevant to disease trajectory (cognition [Mild/Moderate Alzheimer's Disease Composite Score], function [Functional Activities Questionnaire], and total hippocampal volume on magnetic resonance imaging). Secondary clinical outcomes included various cognitive, functional, and neuropsychiatric assessments. Cerebrospinal fluid (CSF) biomarkers spanning multiple pathophysiological pathways in AD were evaluated in participants with both baseline and Week 24 samples (exploratory outcome). RESULTS: PEGASUS enrolled 95 participants (intent-to-treat [ITT] cohort); cognitive assessments indicated significantly greater baseline cognitive impairment in the PB and TURSO (n = 51) versus placebo (n = 44) group. Clinical efficacy outcomes did not significantly differ between treatment groups in the ITT cohort. CSF interleukin-15 increased from baseline to Week 24 within the placebo group (n = 34). In the PB and TURSO group (n = 33), reductions were observed in core AD biomarkers phosphorylated tau-181 (p-tau181) and total tau; synaptic and neuronal degeneration biomarkers neurogranin and fatty acid binding protein-3 (FABP3); and gliosis biomarker chitinase 3-like protein 1 (YKL-40), while the oxidative stress marker 8-hydroxy-2-deoxyguanosine (8-OHdG) increased. Between-group differences were observed for the Aß42/40 ratio, p-tau181, total tau, neurogranin, FABP3, YKL-40, interleukin-15, and 8-OHdG. Additional neurodegeneration, inflammation, and metabolic biomarkers showed no differences between groups. DISCUSSION: While between-group differences in clinical outcomes were not observed, most likely due to the small sample size and relatively short treatment duration, exploratory biomarker analyses suggested that PB and TURSO engages multiple pathophysiologic pathways in AD. Highlights: Proteostasis and mitochondrial stress play key roles in Alzheimer's disease (AD).Sodium phenylbutyrate and taurursodiol (PB and TURSO) targets these mechanisms.The PEGASUS trial was designed to assess PB and TURSO effects on biologic AD targets.PB and TURSO reduced exploratory biomarkers of AD and neurodegeneration.Supports further clinical development of PB and TURSO in neurodegenerative diseases.

A review of immunization legislation for children in English- and Dutch-speaking Caribbean countries / Revisión de los marcos legislativos sobre vacunación infantil en países de habla inglesa y neerlandesa del Caribe / Revisão da legislação relativa à imunização em crianças nos países do Caribe de língua inglesa e holandesa

ABSTRACT Objective. To assess the legislative frameworks concerning childhood vaccination in the English- and Dutch-speaking Caribbean and propose a model legislative framework for Caribbean countries. Methods. This study included a survey of 22 countries and territories in the Caribbean regarding legal vaccination mandates for school entry, budget allocations, sanctions, or exemptions. A legal consultant conducted a comprehensive search and analysis of legislation regarding vaccination among 13 Caribbean countries/territories. A comparative analysis of the legislation under five themes—legislative structure, mandatory vaccination, national immunization schedule, sanctions, and exemptions—formed the basis for the proposed model legislation. Results. Among the 22 Caribbean countries/territories, 17 (77%) had legislation mandating vaccination, 16 (94%) mandated vaccination for school entry, 8 (47%) had a dedicated budget for immunization programs, and 13 (76%) had no legislated national schedules. The source of legislation includes six (35%) using the Education Act, eight (47%) the Public Health Act, and five (29%) a free-standing Vaccination Act. Three countries/territories—Jamaica, Montserrat, and Saint Lucia—had immunization regulations. In 12 (71%) of the 17 countries with legislation, sanctions were included, and 10 (59%) permitted exemptions for medical or religious/philosophical beliefs. Conclusions. Several countries in the Caribbean have made failure to vaccinate a child an offense. By summarizing the existing legislative frameworks and approaches to immunization in the Caribbean, the analysis guides policymakers in making effective changes to immunization legislation in their own countries.

RESUMEN Objetivo. Evaluar los marcos legislativos relativos a la vacunación infantil en el Caribe de habla inglesa y neerlandesa y proponer un modelo de marco legislativo para los países del Caribe. Métodos. En este estudio se incluyó una encuesta en 22 países y territorios del Caribe sobre los requisitos legales de vacunación para el ingreso escolar, asignaciones presupuestarias, sanciones o exenciones. Un consultor jurídico realizó una búsqueda y un análisis exhaustivos de la legislación relativa a la vacunación en 13 países y territorios del Caribe. Un análisis comparativo de la legislación dividido en cinco temas (estructura legislativa, vacunación obligatoria, calendario nacional de vacunación, sanciones y exenciones) formó la base del modelo de legislación propuesto. Resultados. Entre los 22 países y territorios del Caribe, 17 (77%) contaban con leyes sobre vacunación obligatoria, 16 (94%) exigían la vacunación para el ingreso escolar, 8 (47%) tenían un presupuesto dedicado a los programas de vacunación y 13 (76%) no disponían de calendarios nacionales estipulados por ley. Entre las fuentes de la legislación, seis países y territorios (35%) empleaban la ley de educación, ocho (47%) la ley de salud pública y cinco (29%) una ley independiente de vacunación. Tres países y territorios —Jamaica, Montserrat y Santa Lucía— disponían de regulaciones sobre vacunación. Doce (71%) de los 17 países con legislación tenían sanciones y 10 (59%) permitían exenciones por creencias médicas o religiosas o filosóficas. Conclusiones. Varios países del Caribe han tipificado como delito el no vacunar a un niño o niña. Al resumir los enfoques y marcos legislativos existentes para la vacunación en el Caribe, este análisis ofrece orientaciones a los responsables de formular las políticas para que realicen modificaciones efectivas en la legislación relativa a la vacunación en sus propios países.

RESUMO Objetivo. Avaliar as estruturas da legislação relativas à vacinação em crianças no Caribe de língua inglesa e holandesa e propor um modelo de legislação para os países caribenhos. Métodos. Este estudo incluiu uma pesquisa relativa à exigência legal em 22 países e territórios do Caribe de vacinação para admissão em escolas, alocações orçamentárias, sanções ou isenções. Um consultor jurídico realizou ampla pesquisa e análise da legislação relativa à vacinação em 13 países/territórios do Caribe. Uma análise comparativa da legislação referente a cinco temas - estrutura legislativa, vacinação obrigatória, cronograma nacional de imunização, sanções e isenções - formou a base para o modelo de legislação proposto. Resultados. Entre os 22 países/territórios caribenhos, 17 (77%) tinham legislação que exigia a vacinação; em 16 (94%), a vacinação era obrigatória para admissão na escola; 8 (47%) tinham orçamento exclusivo para programas de imunização; e em 13 (76%), a legislação não contemplava cronogramas nacionais. Com relação à fonte da legislação, seis (35%) países usavam a legislação de educação; oito, (47%) a Legislação de Saúde Pública; e cinco (29%), legislação de vacinação independente. Três países/territórios - Jamaica, Montserrat e Santa Lúcia - tinham regulamentações para imunização. Dos 17 países com legislação, 12 (71%) incluíam sanções e 10 (59%) permitiam isenções por crenças médicas ou religiosas/filosóficas. Conclusões. Diversos países do Caribe estabelecem que não vacinar uma criança é violação da lei. Ao resumir as estruturas de legislação existentes e as abordagens da imunização no Caribe, a análise orienta os formuladores de políticas a realizar mudanças efetivas na legislação de imunização em seus próprios países.

MMR2 vaccination coverage and timeliness among children born in 2004 - 2009: a national survey in Saint Lucia, 2015 / Cobertura de vacunación y respeto de los plazos de la segunda dosis de la vacuna triple viral en los niños nacidos en el período 2004-2009: encuesta nacional realizada en Santa Lucía en el 2015 / Cobertura e momento oportuno de vacinação da segunda dose da vacina tríplice viral em crianças nascidas em 2004-2009: pesquisa nacional em Santa Lúcia, 2015

ABSTRACT Objectives To more accurately determine coverage and timeliness of the second dose of measles-mumps-rubella vaccine (MMR2), while identifying factors associated with low MMR2 vaccination uptake among children in Saint Lucia. Methods A survey was conducted in October - November 2015 targeting children born in 2004 - 2009. At 86 preschools and primary schools, two children from each grade were randomly selected, yielding an effective sample of 836 children. Health records were reviewed to assess vaccination coverage and timeliness. Parents and/or guardians and principals of all 86 schools were interviewed regarding knowledge, attitudes, and practices related to vaccination. Results Of 767 children included, 75% were vaccinated with MMR2 (n = 572); 46.7% were vaccinated in a timely manner, i.e., by 5 years of age. Cohorts born in 2004, 2005, and 2008 reported the lowest proportion. 'Mothers as caregivers' was positively associated with timely MMR2 vaccination. Although 97% of principals surveyed considered vaccination important, 48.8% were not aware of national legislation requiring complete vaccination prior to school entry. Survey results concurred with the low MMR2 administrative coverage rates reported by Saint Lucia, much lower than the recommended 95%. Conclusions Based on the results of this survey, Saint Lucia's national immunization program has lowered the age of MMR2 to 18 months in 2016, increased advocacy with schools to enforce the school-entry law, and is working to vaccinate the cohorts of children who have not received timely MMR2.

RESUMEN Objetivos Determinar con mayor precisión la cobertura y el respeto de los plazos de vacunación de la segunda dosis de la vacuna contra el sarampión, la rubéola y la parotiditis (triple viral), al tiempo que se detectan los factores asociados con la baja aceptación de esa vacuna en Santa Lucía. Métodos En octubre y noviembre del 2015 se llevó a cabo una encuesta centrada en niños nacidos entre el 2004 y el 2009. En 86 centros preescolares y primarios se seleccionó al azar a dos niños de cada grado, lo que arrojó un tamaño real de la muestra de 836 niños. Se analizaron los registros de salud para evaluar la cobertura y el respeto de los plazos de vacunación. Se entrevistó a los padres o tutores y los directores de las 86 escuelas sobre conocimientos, actitudes y prácticas en materia de vacunación. Resultados De los 767 niños incluidos, el 75% fueron vacunados con la segunda dosis de la triple viral (n = 572); el 46,7% fueron vacunados a tiempo, es decir, a los 5 años de edad. La proporción más baja se dio en las cohortes nacidas en el 2004, 2005 y 2008. Se observó que las madres cuidadoras influían positivamente en el respeto de los plazos de vacunación de la segunda dosis de la triple viral. Aunque el 97% de los directores encuestados consideraba que la vacunación era importante, el 48,8% desconocía la legislación nacional que exige la vacunación completa antes de ingresar a la escuela. Los resultados de la encuesta estaban en consonancia con las tasas bajas de cobertura administrativa de la segunda dosis de la triple viral informadas por Santa Lucía, muy por debajo del 95% recomendado. Conclusiones Según los resultados de esta encuesta, el programa nacional de vacunación de Santa Lucía redujo la edad de la segunda dosis de la triple viral a los 18 meses en el 2016, aumentó las actividades de promoción en las escuelas para fomentar el cumplimiento de la ley que obliga a recibir la vacunación antes de ingresar a la escuela y está trabajando para vacunar a las cohortes de niños que no recibieron la segunda dosis de la triple viral en su debido momento.

RESUMO Objetivos Determinar com precisão a cobertura vacinal e o momento oportuno para ministrar a segunda dose da vacina tríplice viral (sarampo, caxumba e rubéola - SCR) e identificar os fatores associados à baixa utilização da vacina em crianças. Métodos Uma pesquisa direcionada a crianças nascidas de 2004 a 2009 foi realizada em Santa Lúcia em outubro e novembro de 2015. Em 86 unidades de ensino infantil e fundamental, duas crianças de cada série foram selecionadas aleatoriamente, constituindo uma amostra efetiva de 836 crianças. Dados sobre a cobertura e o momento oportuno de vacinação foram obtidos das fichas de saúde. Foram conduzidas entrevistas com os pais e/ou responsáveis e os diretores das 86 escolas sobre conhecimento, atitudes e práticas relacionadas à vacinação. Resultados Das 767 crianças incluídas na amostra, 75% foram vacinadas com a segunda dose de SCR (n = 572) e 46,7% receberam a vacina no momento oportuno (ou seja, até os 5 anos de idade). Observou-se menor proporção de vacinados nas coortes nascidas em 2004, 2005 e 2008. "Mães como cuidadoras" teve uma associação positiva com ministrar a segunda dose de SCR no momento oportuno. Apesar de 97% dos diretores entrevistados considerarem a vacinação importante, 48,8% desconheciam a legislação nacional que exige vacinação completa para a matrícula escolar. Os resultados reforçaram a baixa cobertura vacinal da segunda dose de SCR registrada em Santa Lúcia, bem inferior ao índice recomendado de 95%. Conclusões A partir dos resultados desta pesquisa, em 2016, o programa nacional de vacinação de Santa Lúcia reduziu para 18 meses a idade de administração da segunda dose de SCR, intensificou a recomendação para que as escolas cumpram com a legislação para matrícula escolar e está empenhado em vacinar as coortes de crianças que não receberam a segunda dose de SCR no momento oportuno.

The Expanded Program on Immunization in the English- and Dutch-speaking Caribbean (1977-2016): reasons for its success / Programa Ampliado de Inmunización en el Caribe de habla inglesa y holandesa (1977-2016): las razones de su éxito / Programa Ampliado de Imunização nos países do Caribe de língua inglesa e holandesa (1977-2016): motivos para um programa bem-sucedido

ABSTRACT The year 2017 marks the 40th year of the establishment of the Expanded Program on Immunization (EPI) by the Pan American Health Organization (PAHO), the regional office of the World Health Organization (WHO) in the Americas, the first WHO region certified as eliminating poliomyelitis (1994), measles (2016), and rubella and congenital rubella syndrome (CRS) (2015). The English- and Dutch-speaking Caribbean subregion of the Americas paved the way in eliminating these diseases. This report highlights the innovative strategies used in this subregion that helped make the EPI a success. A review of published/unpublished reports and written and oral accounts of the experiences of Immunization Advisors and national EPI managers was conducted to identify the strategies used to strengthen the Immunization program in the subregion since its implementation by countries in 1977. The results show that these include strong collective political commitment, country-specific immunization legislation, joint use of a standard coverage monitoring chart, annual meetings of national EPI managers, collaborative development of annual national Plans of Action for Immunization, coordinated implementation of vaccination campaigns, subregional oversight of surveillance and laboratory support, a performance award system for countries, and subregional standardized templates for immunization manuals and procedural guidelines. Political will and support for immunization has been particularly strong in this subregion, where 99% of EPI costs are borne by governments. Dedicated health staff and multi-country agreement and application of strategies have led to high sustained coverage and good-quality surveillance, resulting in the absence of wild polio for 34 years, measles for 25 years, CRS for 17 years, and rubella for 15 years.

RESUMEN En el 2017 se celebra el cuadragésimo año de la instauración del Programa Ampliado de Inmunización (PAI) por la Organización Panamericana de la Salud (OPS), la Oficina Regional de la Organización Mundial de la Salud (OMS) para las Américas. Esta fue la primera región de la OMS que obtuvo la certificación de la eliminación de la poliomielitis (1994), el sarampión (2016) y la rubéola y el síndrome de rubéola congénita (2015). La subregión de habla inglesa y holandesa del Caribe en las Américas abrió el camino a la eliminación de estas enfermedades. En el presente artículo se destacan las estrategias innovadoras utilizadas en esta subregión que contribuyeron al éxito del PAI. Se llevó a cabo una revisión de los informes publicados e inéditos y de los relatos escritos y orales de las experiencias de los Expertos en Inmunización y los gerentes nacionales del PAI con el objeto de determinar las estrategias utilizadas con miras a fortalecer el programa de vacunación en la subregión, desde su introducción en los países en 1977. Los resultados ponen de manifiesto que los programas comportaban un fuerte compromiso político colectivo, legislaciones en materia de inmunización propias de cada país, la utilización común de un registro gráfico normalizado de monitoreo de coberturas de vacunación, reuniones anuales de los gerentes nacionales del PAI, la elaboración conjunta de planes de acción anuales nacionales sobre vacunas, la ejecución coordinada de campañas de vacunación, la supervisión de la vigilancia y el apoyo a los laboratorios a escala subregional, un sistema de reconocimiento al desempeño de los países y plantillas subregionales normalizadas de los manuales de vacunación y los procedimientos recomendados. La voluntad política y el apoyo a la vacunación han sido muy sólidos en esta subregión, donde los gobiernos sufragan 99% de los costos del PAI. La existencia de personal sanitario dedicado y los acuerdos multinacionales y la aplicación de las estrategias permitieron alcanzar una alta cobertura de manera sostenida y una vigilancia de buena calidad, cuyo resultado fue la ausencia de poliomielitis salvaje durante 34 años, de sarampión durante 25 años, del síndrome de la rubéola congénita durante 17 años y de la rubéola durante 15 años.

RESUMO O ano de 2017 marca o 40° aniversário da criação do Programa Ampliado de Imunização (PAI) pela Organização Pan-Americana da Saúde (OPAS), Escritório Regional da Organização Mundial da Saúde (OMS) nas Américas, primeira Região da OMS certificada como tendo eliminado a poliomielite (1994), o sarampo (2016) e a rubéola e síndrome da rubéola congênita (2015). A sub-região das Américas constituída pelos países do Caribe de língua inglesa e holandesa abriu caminho ao eliminar essas doenças. Este relato destaca as estratégias inovadoras usadas nesta sub-região que contribuíram para tornar o PAI um programa bem-sucedido. Foi realizada uma análise de informes publicados/inéditos e relatos orais e escritos da experiência dos assessores para assuntos de imunização e coordenadores nacionais do PAI visando identificar as estratégias aplicadas para consolidar o programa nos países da sub-região desde a sua implementação em 1977. Os resultados demonstram firme compromisso político coletivo, legislação de vacinação própria em cada país, uso conjunto de uma lista padrão para o monitoramento da cobertura, reuniões anuais dos coordenadores nacionais do PAI, desenvolvimento colaborativo de planos de ação nacionais anuais para vacinação, campanhas coordenadas de vacinação, supervisão sub-regional da vigilância e infraestrutura laboratorial, sistema de premiação dos países por bom desempenho, modelos padronizados para os manuais de vacinação e protocolos de procedimentos. A sub-região se caracteriza sobretudo pela vontade e apoio políticos para vacinação, sendo 99% do custo do PAI financiados pelos governos. Equipes de saúde diligentes, acordos entre vários países e emprego de estratégias são fatores que contribuem para elevada cobertura sustentada e vigilância de boa qualidade com a consequente não ocorrência de casos de poliomielite por vírus selvagem por 34 anos, de casos de sarampo por 25 anos, de casos de síndrome da rubéola congênita por 17 anos e de casos de rubéola por 15 anos.

Genital human papillomaviruses among women of reproductive age in Jamaica / Virus de los papilomas humanos genitales en mujeres en edad reproductiva de Jamaica

OBJECTIVE: To characterize the prevalence and distribution of genital human papillomavirus (HPV) types among women in Jamaica, and to explore risk factors associated with HPV infection. METHODS: This was a cross-sectional study that took place in April-July 2010 with 852 sexually-active women, 16-49 years of age, who had attended a selected public or private primary health clinic in one of Jamaica's four health authority regions. Sociodemographic data was collected from each participant by trained study staff. Each participant had a gynecological examination that included a clinical Pap test and a cervical sample for HPV detection and typing-performed using the Research Use Only Linear Array (LA) genotyping assay (Roche Diagnostics Corp., Indianapolis, Indiana, United States). Overall and type-specific prevalence of HPV infection was calculated for 37 HPV types included in the LA genotyping assay. RESULTS: HPV DNA was detected in 460 of the 852 women (54.0%). Oncogenic HPV was detected in 297 women (34.9%) and HPV types 16/18 were found in 86 women (10.1%). The most frequently occurring HPV types were: 16 (6.2%); 35 (6.0%); 62 and 83 (5.5%); 61 and 58 (5.4%); 84 (4.7%); 18 (4.3%); and, 66 and 81 (4.2%). HPV prevalence was highest among women who were single, young (16-19 years), and had had more than three sexual partners in their lifetime. CONCLUSIONS: These results, coupled with high rates of cervical cancer, support introducing HPV vaccines while maintaining and strengthening cervical cancer screening services. Policy decisionmaking that reflects these results is instrumental to establishing a comprehensive cervical cancer program in Jamaica.

OBJETIVO: Determinar la prevalencia y la distribución de los tipos de virus de los papilomas humanos (VPH) genitales en las mujeres de Jamaica y explorar los factores de riesgo asociados con la infección por VPH. MÉTODOS: Este estudio transversal se llevó a cabo de abril a julio del 2010. Participaron 852 mujeres sexualmente activas, de 16 a 49 años de edad, que acudieron a uno de los consultorios públicos o privados de atención primaria seleccionados en cada una de las cuatro autoridades sanitarias regionales de Jamaica. Personal capacitado del estudio recopiló datos sociodemográficos de cada participante. Todas las participantes fueron sometidas a un examen ginecológico que comprendía una prueba clínica de Papanicolaou y la obtención de una muestra del cuello uterino a efectos de detectar y tipificarlos VPH mediante la prueba de genotipado Linear Array (LA) (Roche Diagnostics Corp., Indianápolis, Indiana, Estados Unidos), de uso exclusivo en investigación. Se calcularon las prevalencias global y específica de tipo de la infección por VPH para los 37 tipos de VPH incluidos en la prueba de genotipado LA. RESULTADOS: Se detectó ADN de VPH en 460 de las 852 mujeres (54,0%). Se detectaron VPH oncógenos en 297 mujeres (34,9%), y VPH de los tipos 16 y 18 en 86 mujeres (10,1%). Los tipos de VPH detectados con mayor frecuencia fueron 16 (6,2%), 35 (6,0%), 62 y 83 (5,5%), 61 y 58 (5,4%), 84 (4,7%), 18 (4,3%), y 66 y 81 (4,2%). La prevalencia de VPH fue más elevada en mujeres solteras, jóvenes (de 16 a 19 años) y que habían tenido más de tres compañeros sexuales en sus vidas. CONCLUSIONES: Estos resultados, junto a las elevadas tasas de cáncer cervicouterino, fundamentan la introducción de las vacunas contra el VPH al tiempo que se mantienen y refuerzan los servicios de tamizaje del cáncer cervicouterino. Las decisiones políticas que se adopten como consecuencia de estos resultados serán determinantes para establecer un programa integral contra el cáncer cervicouterino en Jamaica.
