RESUMEN

ABSTRACT Objective: The prevalence of sub-dermal contraceptive implant use in Jamaica is low, despite growing international acceptance of long-acting reversible contraception. This study assessed the availability, effectiveness, side-effects and utilization of sub-dermal contraceptive implants and described the characteristics of users over a one-year period. Methods: We reviewed the medical records of women aged 15-45 years who utilized contraceptive implant-related services at any of the six included public health centres in Jamaica during 2013, and surveyed 20 available reproductive healthcare providers. Results: In 2013, 738 women attended a Jamaican public health centre for contraceptive implant services: 493 (66.8%) for insertion, 202 (27.4%) for removal and 53 (7.2%) for follow-up visits (10 women had the same implant inserted and removed in 2013). The women's median age was 26.0 years, 24.3% were ≤ 18 years, and 85.9% had ≥ 1 child. Most women (68.5%) did not have documented side-effects; irregular bleeding, the most commonly documented side-effect, was recorded for 24%. Of the 493 women who had implants inserted, three (0.6%) were identified to be pregnant within three months of insertion. Among the 202 women who had implants removed, 11 (5.4%) experienced complications with removal. Reproductive healthcare providers highlighted the need for an expansion of contraceptive implant availability and provider training. Conclusion: Sub-dermal implants have few insertion complications and side-effects and are effective, but were underutilized in Jamaica. Increased implant availability and enhanced reproductive healthcare provider training may improve implant utilization and reduce unintended pregnancy rates in Jamaica.

RESUMEN Objetivo: La prevalencia del uso de implantes anticonceptivos subdérmicos en Jamaica es baja, a pesar de la creciente aceptación internacional de la anticoncepción reversible de acción prolongada. El presente estudio evalúa la disponibilidad, efectividad, efectos secundarios y utilización de los implantes anticonceptivos subdérmicos, y describe las características de los usuarios durante el período de un año. Métodos: Se revisaron las historias clínicas de mujeres de 15 a 45 años de edad, que utilizaron servicios relacionados con los implantes anticonceptivos en cualquiera de los seis centros de salud pública de Jamaica durante 2013, y se encuestaron 20 profesionales de salud reproductiva disponibles. Resultados: En 2013, 738 mujeres asistieron a un centro de salud pública de Jamaica para recibir servicios de implantes anticonceptivos: 493 (66.8%) para inserción, 202 (27.4%) para eliminación, y 53 (7.2%) para visitas de seguimiento (a 10 mujeres se les insertó y se les quitó el mismo implante en 2013). La edad promedio de las mujeres fue 26.0 años, 24.3% tenían ≤ 18 años, y el 85.9% tenían ≥ 1 niño. La mayoría de las mujeres (68.5%) no presentaban efectos secundarios documentados. El sangramiento irregular - el efecto secundario más comúnmente documentado - se registró en un 24%. De las 493 mujeres que tenían implantes insertados, se halló que tres (0.6%) resultaron embarazadas en el plazo de tres meses tras la inserción. De las 202 mujeres a las que se les había retirado el implante, 11 (5.4%) tuvieron complicaciones en el proceso de la eliminación. Los profesionales de la salud reproductiva destacaron la necesidad de expandir la disponibilidad de implantes anticonceptivos y la capacitación de proveedores. Conclusión: Los implantes subdérmicos presentan pocas complicaciones a la hora de su inserción, y tienen pocos efectos secundarios. Sin embargo, son subutilizados en Jamaica, a pesar de ser efectivos. Una mayor disponibilidad de implantes y una mejor capacitación de los profesionales de la salud reproductiva pueden mejorar la utilización de implantes y reducir las tasas de embarazos no intencionados en Jamaica.

RESUMEN

The prevalence of antibodies to HTLV in women attending a south east London antenatal clinic between October 1990 and July 1992 was determined using sera referred for rountine rubella antibody testing. Samples were screened for HTLV antibody using a modified Fujirebio gel particle agglutination test and reactive sera confirmed by ELISA (Abbott Laboratories, North Chicago, IL) and two commercial Western blots (Cambridge Biotech Inc., Rockville, MD, and Diagnostic Biotechnology, Genelab Diagnostics, Louvaine, Belgium). This strategy confirmed the presence of HTLV-1 antibodies in 12 out of 6,289 sera (0.19 percent, 95 percent confidence limits 0.083 percent to 0.30 percent) and HTLV-2 antibodies in 2 (0.03 percent) sera. Specimens from 8 to 821 (0.97 percent, 95 percent confidence limits 0.42 percent to 1.9 percent). Afro-Caribbean women, three of 1,136 (0.26 percent, 95 percent confidence limits 0.055 percent to 0.78 percent). African women, and one of 3,049 (0.033 percent, 95 percent confidence limits 0.006 percent to 0.18 percent). Caucasian women were positive for HTLV-1 antibodies. Sera from Afro-Caribbean women born in the Caribbean were 7.6 times more likely to be HTLV-1 antibody positive than sera from Afro-Caribbean women born in the UK (P = 0.012). Selective testing of Afro-Caribbean and African antenatal clinic attenders, in this setting, would have identified 11 of the 12 HTLV-1 infections at an estimated cost of prevention of HTLV-1 associated disease of 100,000 pounds per case which is considerably less than the 1.3 million pounds which has been estimated to prevent a case by universal screening of UK blood donors.(AU)

RESUMEN

GM and KM allotypes, powerful tools for genetic characterization of human populations, have been shown to play an important role in genetic predisposition to some infectious diseases. Two diverse racial groups--Afro-Ecuadorians and Amerindians--living in a single restricted geographical area of Ecuador, appear to have different risk factors for acquisition and clinical expression of onchocerciasis, a disease caused by the filarial parasite Onchocerca volvulus. In this study, GM and KM allotypes were determined in 25 Afro-Ecuadorians and 24 Amerindians infected with Onchocerca volvulus (INF) and in putative immune individuals (PI). In Afro-Ecuadorians, the frequency of the homozygous KM 3 phenotype was significantly decreased in INF as compared with the PI group (20 vs. 68%; P= 0.0012), while the frequency of the heterozygous KM 1,3 phenotype was increased in INF as compared with the PI subjects (48 vs. 9%; P= 0.0044). These results suggest that in Afro-Ecuadorians KM 3 is associated with a lower relative risk (resistance), whereas KM 1,3 is associated with an increased risk (susceptibility) of onchocerciasis.
