The HIV continuum of care in the Bahamas in 2014 / El proceso continuo de atención de la infección por el VIH en las Bahamas en el 2014

ABSTRACT Objective The HIV cascade of care describes the spectrum of engagement in HIV care from diagnosis to viral suppression (VS). The study objective was to develop a baseline HIV cascade of care for new HIV diagnoses in the Bahamas in 2014. Methods Individuals who were newly diagnosed with HIV in 2014 and known to be alive within a year of that diagnosis were included in the cascade of care (n = 250). Individuals with one CD4 or HIV viral load (VL) measure in 2014 were considered linked to care. Those with at least two CD4 counts in the year were considered retained in care. Eligibility for antiretroviral therapy (ART) was based on having a CD4 count < 350 cells/mm3. ART adherence was defined as filled prescriptions > 11 months/year. VL < 1 000 copies/ml was considered suppressed. Comparisons were made in the cascades by gender and age. Results Of the 250 persons in the study, 79 of them (32%) were retained in care. Antiretrovirals (ARVs) were prescribed to 116 of the 250 (46%); of those 116, 48 of them (41%) achieved VS. A higher proportion of women achieved VS than did men, but this difference did not reach statistical significance. Similarly, there were differences in VS based on age, but the differences were not statistically significant. Conclusions In the Bahamas, increased efforts are needed to help people living with HIV to link to and be retained in care. VS may remain suboptimal unless ART is scaled up and adherence interventions are included in measures to improve the treatment cascade.

RESUMEN Objetivo El proceso continuo de la atención de la infección por el VIH describe el espectro de intervenciones en la atención de la infección, desde el diagnóstico hasta la supresión viral. El objetivo del estudio fue elaborar un proceso continuo de la atención como punto de referencia y comparación para nuevos diagnósticos de infección por el VIH en las Bahamas en el 2014. Métodos En el proceso continuo de la atención se incluyó a personas con diagnóstico de infección por el VIH en el 2014 y que continuaban vivas a un año del diagnóstico (n = 250). Se consideró vinculadas a la atención a aquellas personas con un recuento de linfocitos CD4 o una medición de la carga viral de VIH en el 2014. Aquellas con al menos dos recuentos de CD4 en el año se consideraron retenidas en la atención. La aptitud para el tratamiento antirretroviral se basó en tener un recuento de CD4 < 350 células/mm3. Se definió adherencia al tratamiento antirretroviral como la entrega de la prescripción >11 meses/año. Se consideró supresión viral a una carga viral de < 1 000 copias/ml. Se hicieron comparaciones en las cascadas por sexo y edad. Resultados De las 250 personas que participaron en el estudio, 79 (32%) se retuvieron en la atención. Se prescribieron antirretrovirales a 116 de las 250 personas (46%); de estas 116 personas, 48 (41%) lograron la supresión viral. Las mujeres lograron la supresión viral en una proporción mayor que los hombres, pero esta diferencia no fue estadísticamente significativa. Igualmente, se observaron diferencias en la supresión viral según la edad, pero estas tampoco fueron estadísticamente significativas. Conclusiones En las Bahamas, es necesario incrementar los esfuerzos para ayudar a las personas con infección por el VIH a vincularse y mantenerse en la atención. La supresión viral puede permanecer en niveles subóptimos a menos que se amplíe el tratamiento antirretroviral y se incluyan intervenciones de adherencia terapéutica en las medidas para mejorar el proceso continuo de la atención.

The impact of helmets on motorcycle head trauma at a tertiary hospital in Jamaica.

BACKGROUND: Although the Jamaica road traffic act mandates motorcycle riders to wear approved helmets, opponents suggest that the local road conditions obviate any benefits from helmet use that have been proven in Developed countries. They suggest that the narrow, winding, poorly surfaced, congested local highways do not allow motorcyclists to sustain high velocity travel. The accidents then tend to occur at lower speeds and are accompanied by less severe injuries. This study was carried out to determine the impact of helmet use on traumatic brain injuries from motorcycle collisions in patients admitted to a tertiary referral hospital in Jamaica. METHODS: A prospectively collected trauma registry maintained by the Department of Surgery at the University Hospital of the West Indies in Jamaica was accessed to identify all motorcycle collision victims from January 2000 to January 2007. The therapeutic outcomes of traumatic brain injuries were compared between helmeted and un-helmeted riders. The data was analyzed using SPSS Version 12. RESULTS: Of 293 motorcycle collision victims, 143 sustained brain injuries. There were 9 females (6.3%) with an average age of 23 +/- 7.3 years and 134 males (93.7%) at an average age of 33.4 +/- 11.2 years (mean +/- SD). Only 49 (34.3%) patients wore a helmet at the time of a collision. Helmet use at the time of a collision significantly reduced the severity of head injuries (28.6% vs 46.8%, P = 0.028) and the likelihood of sustaining intra-cranial lesions (26.5% vs 44.7%, P = 0.03) from head injuries. CONCLUSION: Wearing a helmet at the time of a motorcycle collision reduces the severity of head injuries. However, the prevalence of helmet use at the time of a collision is unacceptably low.

Access surgery for hemodialysis in the Cayman Islands: Preliminary results of a vascular access service.

OBJECTIVE: In the Cayman Islands, a vascular access service was created in 2005 to facilitate the creation of vascular access for hemodialysis by local surgeons. The present retrospective audit aims to establish the outcomes of this practice in the Cayman Islands. METHODS: Data from the operative log of the Cayman Islands Hospital was collected over a period of 36 months. The data were analyzed using SPSS version 12.0 (SPSS Inc, USA). Statistical analyses were performed using Student's t tests and Fisher's exact tests. RESULTS: A total of 19 operative procedures were performed to create vascular accesses in 12 men and seven women. Thirteen procedures (68%) created autogenous arteriovenous fistulas (AVFs) and six (32%) involved the insertion of a prosthetic arteriovenous graft (AVG). There were six incident dialysis patients, all of whom had an AVF created. The remaining 13 prevalent dialysis patients had new accesses in the form of AVFs (n=7) or AVGs (n=6). The statistical analyses were limited by sample size, but with AVFs, there were trends toward reduced incidence of secondary failure (four of 13 versus four of six), thrombosis (four of 13 versus two of six), infectious morbidity (zero versus two of six) and less demand for interventions to maintain patency (one of 13 versus two of six) with AVFs. There were also trends toward superior primary (461 days versus 227 days) and secondary (803 days versus 205 days) patency rates for AVFs. CONCLUSIONS: In this setting, the rate of AVF creation exceeds the goals set by the National Kidney Foundation Kidney Disease Outcomes Quality Initiative and the Fistula First Breakthrough Initiative. To ensure continued delivery of modern quality care, further audits of the local practice will be required at regular intervals.
