RESUMO
OBJECTIVE: To define major congenital anomaly (CA) subgroups and assess outcome variability based on defined subgroups. STUDY DESIGN: This population-based cohort study used registries in Denmark for children born with a major CA between January 1997 and December 2016, with follow-up until December 2018. We performed a latent class analysis (LCA) using child and family clinical and sociodemographic characteristics present at birth, incorporating additional variables occurring until age of 24 months. Cox proportional hazards regression models estimated hazard ratios (HRs) of pediatric mortality and intensive care unit (ICU) admissions for identified LCA classes. RESULTS: The study included 27 192 children born with a major CA. Twelve variables led to a 4-class solution (entropy = 0.74): (1) children born with higher income and fewer comorbidities (55.4%), (2) children born to young mothers with lower income (24.8%), (3) children born prematurely (10.0%), and (4) children with multiorgan involvement and developmental disability (9.8%). Compared with those in Class 1, mortality and ICU admissions were highest in Class 4 (HR = 8.9, 95% CI = 6.4-12.6 and HR = 4.1, 95% CI = 3.6-4.7, respectively). More modest increases were observed among the other classes for mortality and ICU admissions (Class 2: HR = 1.7, 95% CI = 1.1-2.5 and HR = 1.3, 95% CI = 1.1-1.4, respectively; Class 3: HR = 2.5, 95% CI = 1.5-4.2 and HR = 1.5, 95% CI = 1.3-1.9, respectively). CONCLUSIONS: Children with a major CA can be categorized into meaningful subgroups with good discriminative ability. These groupings may be useful for risk-stratification in outcome studies.

OBJECTIVE: Venous insufficiency is a prevalent and potentially debilitating disease. Treatment guidelines and techniques such as radiofrequency ablation (RFA) developed in the United States and Europe have been shown to provide significant improvements in quality of life; however, these have not been clearly assessed in the populations of developing nations. This study examined quality of life outcomes after RFA of patients treated at a single Jamaican vein center. METHODS: In this study, 100 patients who underwent RFA from 2007 to 2012 were evaluated. Patients answered the Venous Insufficiency Epidemiological and Economic Study on Quality of Life/Symptoms (VEINES-QOL/Sym) questionnaire assessing quality of life before and after RFA. Improvements in specific categories, such as venous symptoms, work limitations, social limitations, and cosmetic concerns, were evaluated. Cumulative VEINES-Sym and VEINES-QOL scores were also assessed. RESULTS: Patients' quality of life responses were significantly improved in every individual VEINES question. Average cumulative VEINES-Sym t score improved 9.96 points (P < .01), and VEINES-QOL t score improved 11.15 points (P < .01). For patients with Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) C5 and C6 disease, the only questions that did not show significant improvement were limitations to daily workplace activity and impact on clothing after RFA. However, in this subset, the average VEINES-Sym t score improved 11.83 points (P < .01), and the VEINES-QOL t score improved 11.96 points (P < .01) after RFA. CONCLUSIONS: Venous disease is often overlooked, and access to treatment can be limited in developing nations. This study demonstrated that venous treatment guidelines and RFA techniques developed in the United States and Europe could be successfully applied to a Jamaican population, resulting in significant improvements in quality of life.

OBJECTIVE: Colorectal carcinoma (CRC) is the third most common cancer and a leading cause of cancer-related deaths in Jamaica. Globally, CRC mortality rates have been decreasing in developed countries; however, CRC mortality rates are trending upwards in low-income or developing countries. Our objectives are to estimate the overall 5-year survival and to determine the pathologic factors associated with overall survival of colorectal adenocarcinoma after surgery at the University Hospital of the West Indies (UHWI). METHODS: Retrospective, observational (cross-sectional) study on CRC patients. We summarized and analyzed demographic, clinical data, histopathological data, and survival rates. Single predictor Cox regression models were used to establish associations between survival and specified clinicopathological characteristics. RESULTS: A total of 217 patients who underwent operative resection of colorectal adenocarcinoma from January 2004 to December 2013. Median survival time post-therapeutic intervention was 48 months. Late stage at diagnosis, positive circumferential resection margins, neural and vascular invasion, as well as three or more nodal metastases were all associated with statistically significant worsened outcome. CONCLUSIONS: Despite surgical quality meeting USA standards, CRC survival rates in Jamaica are 13% lower than survival of CRC in non-Hispanic Blacks in the USA. The survival trends found by our study support the application of international indices for CRC prognostication to Jamaican patients.

INTRODUCTION: The commonest variation to the classic anatomic description of renal arterial supply is the presence of accessory renal arteries. The incidence varies widely according to ethnicity. There is no data on the prevalence of these anomalies in persons of Caribbean ethnicity. METHODS: All CT scans done over two years from July 1, 2010 to June 30, 2012 were retrospectively evaluated. The anatomy of the renal arterial supply was reported from these studies and the anatomy of accessory renal arteries was documented. RESULTS: There were 302 CT scans evaluated and accessory renal arteries were present in 109/302 (36.1%) CT scans, 95% confidence interval 30.6%, 41.4%. There were 71/309 (23.5%) patients with accessory arteries on the left and 54/309 (17.9%) had them on the right (p 0.087). Of these, 16 (14.7%) patients had bilateral accessory renal arteries present. The most common origin for the accessory arteries was the abdominal aorta in 108 (99.1%) cases and in 1 case the accessory artery arose from the coeliac trunk. There were 80 left sided accessory renal arteries: 17 (21.3%) upper polar and 27 (33.8%) lower polar arteries. Of 62 right sided accessory arteries, 14 (22.6%) were upper polar and 26 (42%) were lower polar arteries. CONCLUSION: This is the first population-based report of anatomic anomalies in renal arterial supply in a Caribbean population. These are important findings that may affect vascular and urologic procedures on persons of Caribbean ethnicity.
RESUMO
BACKGROUND AND PURPOSE: The purpose of this study was to determine the prevalence of carotid stenosis among patients presenting to the University Hospital of West Indies (UHWI) Accident and Emergency Department (A&E) with an ischemic stroke or transient ischemic attack (TIA). METHODS: Beginning in August 2006, all patients presenting to the UHWI A&E with an acute stroke or TIA were screened for enrollment. Patients were excluded if they had a hemorrhagic stroke or if informed consent could not be obtained. Demographic and clinical information were collected by chart review and interviewer-administered questionnaires. All participants had noncontrast head computed tomography (CT) and bilateral carotid duplex ultrasounds. RESULTS: 133 patients were enrolled in the study. 90% presented with a stroke and 10% with a TIA. Mean age was 64 years, 52% were male, 96% self-identified as black. 78% had diabetes mellitus or hypertension or both, 27% were current or past smokers. 65.1% had a normal carotid ultrasound, 28.5% had <50% stenosis, 1.6% had 50% to 69% stenosis, 0.8% had >or=70% stenosis to near occlusion, 1.6% had near occlusion and 1.6% total occlusion. CONCLUSIONS: The prevalence of moderate or high-grade carotid stenosis in this high-risk black Caribbean population presenting with an ischemic stroke or a TIA is 5.6%. This is lower than that described in other populations. Further studies are needed to determine the cost-effectiveness of routine screening for carotid stenosis in this population.

BACKGROUND: The demand for vascular hemodialysis access creation is steadily increasing. To satisfy the demand, a vascular access team was established at the University Hospital of the West Indies, Jamaica. The outcomes of this practice are reported. METHODS: A retrospective study of all patients who had permanent vascular dialysis access established at the University Hospital of the West Indies between January 1, 2002, and December 31, 2006, was performed. Data were analyzed using SPSS version 12.0 (SPSS Inc, USA). A direct anastomosis between an autogenous artery and vein was considered an arteriovenous fistula (AVF). When prosthetic material was used, the access was considered to be an arteriovenous graft. Accesses that were nonfunctional after six weeks of maturation were considered to be primary failures, while those that failed after previous successful dialysis were considered to be secondary failures. Primary patency was defined as the interval between access placement and the first intervention for failure. Secondary patency was the interval between access placement and abandonment. Cumulative patency was defined as the number of accesses that remained patent over a given time period, regardless of the number of interventions performed. RESULTS: Of 41 patients, nine were excluded due to incomplete data. Final analyses were performed on 32 patients with a mean (± SD) age of 42.3±15.3 years (range 18 to 66 years, median 43 years). The access type was an AVF in 100% of cases, which included distal radiocephalic fistulas in 27 patients, brachial-cephalic fistulas in three patients and proximal radiocephalic fistulas in two patients. Operations were performed in four (12.5%) incident and 28 (87.5%) prevalent dialysis patients. The mean delay between initiation of dialysis and AVF creation was 21.2±26.1 months (range one to 94 months, median 10 months). There were eight (25%) primary failures. Of the remaining 24 patients, there were seven (29.2%) secondary failures from thrombosis. There was primary patency for a mean of 723.9±422.1 days (range 199 to 1314 days, median 678 days). Only one (4.2%) patient had thrombectomy to prolong AVF function, resulting in secondary patency for 439 days. Cumulative patency was 62.5%, 33.3%, 25% and 4.2% for one, two, three and four years, respectively. CONCLUSIONS: The rate of AVF creation for end-stage renal disease patients in this setting far exceeds the target goals set forward by the National Kidney Foundation published updated Dialysis Outcomes Quality Initiative (NKF/DOQI) Guidelines and the Centers for Medicaid & Medicare Services Fistula First initiative. This is being achieved with acceptable rates of morbidity and patency. There is room for improvement in postoperative surveillance to increase early detection of failing accesses and allow for increased utility of interventions for assisted patency.
