Risk factors associated with severe COVID-19 outcomes in Jamaica: a cross-sectional study of national surveillance data / Factores de riesgo asociados a la COVID-19 grave en Jamaica: estudio transversal de datos nacionales de vigilancia / Fatores de risco associados a desfechos graves da COVID-19 na Jamaica: estudo transversal de dados de vigilância nacional

[ABSTRACT]. Objectives. To describe the characteristics and outcomes of COVID-19 cases in Jamaica and to explore the risk factors associated with severe COVID-19 from 9 March to 31 December 2020. Methods. A cross-sectional analysis of national surveillance data was conducted using confirmed COVID-19 cases in Jamaica. Definitions of a confirmed case, disease severity, and death were based on World Health Organization guidelines. Chi-square and Fisher exact tests were used to determine association with outcomes. Logistic regression models were used to determine predictors of severe COVID-19. Results. This analysis included 12 169 cases of COVID-19 (median age, 36 years; 6 744 females [ 55.4%]) of which 512 cases (4.2%) presented with severe disease, and of those, 318 patients (62.1%) died (median age at death, 71.5 years). Severe disease was associated with being male (OR 1.4; 95% CI, 1.2-1.7) and 40 years or older (OR, 6.5; 95% CI, 5.1-8.2). COVID-19 death was also associated with being male (OR, 1.4; 95% CI, 1.1-1.7), age 40 years or older (OR, 17.9; 95% CI, 11.6-27.7), and in the Western versus South East Health Region (OR 1.7; 95% CI, 1.2-2.3). Conclusions. The findings of this cross-sectional analysis indicate that confirmed cases of COVID-19 in Jamaica were more likely to be female and younger individuals, whereas COVID-19 deaths occurred more frequently in males and older individuals. There is increased risk of poor COVID-19 outcomes beginning at age 40, with males disproportionately affected. COVID-19 death also varied by geographic region. This evidence could be useful to other countries with similar settings and to policymakers charged with managing outbreaks and health.

[RESUMEN]. Objetivos. Describir las características y los resultados de los casos de COVID-19 en Jamaica y explorar los factores de riesgo asociados a la COVID-19 grave desde el 9 de marzo hasta el 31 de diciembre del 2020. Métodos. Se realizó un análisis transversal de datos nacionales de vigilancia a partir de los casos confirma- dos de COVID-19 en Jamaica. Las definiciones de caso confirmado, gravedad de la enfermedad y muerte se basaron en las directrices de la Organización Mundial de la Salud. Para determinar la asociación con los criterios de valoración se utilizó la prueba de χ2 y la prueba exacta de Fisher. Se usaron modelos de regresión logística para determinar los factores predictivos de la COVID-19 grave. Resultados. Se incluyeron en el análisis 12 169 casos de COVID-19 (mediana de edad, 36 años; 6 744 mujeres [55,4%]), de los que 512 (4,2%) fueron de enfermedad grave. De estos pacientes, 318 (62,1%) fall- ecieron (mediana de edad al morir, 71,5 años). Se observó una asociación de la enfermedad grave con el sexo masculino (OR de 1,4; IC del 95 %, 1,2-1,7) y con la edad igual o superior a 40 años (OR de 6,5; IC del 95 %, 5,1-8,2). La muerte por COVID-19 también mostró una asociación con el sexo masculino (OR de 1,4; IC del 95%, 1,1-1,7), con la edad igual o superior a 40 años (OR de 17,9; IC del 95%, 11,6-27,7) y con la Región de Atención de Salud Occidental en comparación con la Sudoriental (OR de 1,7; IC del 95%, 1,2-2,3). Conclusiones. Los resultados de este análisis transversal indican que los casos confirmados de COVID-19 en Jamaica correspondieron una mayor probabilidad a mujeres y personas más jóvenes, mientras que las muertes por COVID-19 fueron más frecuentes en varones y personas de mayor edad. Hay un mayor riesgo de evolución desfavorable de la COVID-19 a partir de los 40 años, que afecta de manera desproporcionada a los varones. Las muertes por COVID-19 también variaron según la región geográfica. Esta evidencia podría ser de utilidad para otros países con entornos similares y para los responsables de la formulación de políticas en materia de gestión de brotes y salud.

Sodium and potassium consumption in Jamaica: National estimates and associated factors from the Jamaica Health and Lifestyle Survey 2016-2017.

This study aimed to estimate dietary sodium and potassium consumption among Jamaicans and evaluate associations with sociodemographic and clinical characteristics. A cross-sectional study was conducted using data from the Jamaica Health and Lifestyle Survey 2016-2017. Participants were noninstitutionalized Jamaicans aged ≥15 years. Trained staff collected sociodemographic and health data via interviewer-administered questionnaires and spot urine samples. The Pan American Health Organization formula was used to estimate 24-hour urine sodium and potassium excretion. High sodium level was defined as ≥2000 mg/day, and low potassium levels as <3510 mg/day (World Health Organization criteria). Associations between these outcomes and sociodemographic and clinical characteristics were explored using multivariable ANOVA models using log-transformed 24-hour urine sodium and potassium as outcome variables. Analyses included 1009 participants (368 males, 641 females; mean age 48.5 years). The mean sodium excretion was 3582 mg/day (males 3943 mg/day, females 3245 mg/day, P < .001). The mean potassium excretion was 2052 mg/day (males, 2210 mg/day; females, 1904 mg/day; P = .001). The prevalence of high sodium consumption was 66.6% (males 72.8%, females 60.7%, P < .001) and that of low potassium intake was 88.8% (85.1% males, 92.3% females, P < .001). Sodium consumption was inversely associated with older age, higher education, and low glomerular filtration rate but was directly associated with being male, current smoking, and obesity. Overall, males had higher sodium consumption than women, with the effect being larger among hypertensive men. Women with hypertension had lower sodium consumption than nonhypertensive women; however, hypertensive men had higher sodium consumption than nonhypertensive men. Potassium consumption was higher among men, persons with obesity, and those with high total cholesterol but was lower among men with "more than high school" education compared to men with "less than high school" education. We conclude that most Jamaican adults have diets high in sodium and low in potassium. In this study, sodium consumption was directly associated with male sex, obesity, and current smoking but was inversely associated with older age and higher education. High potassium consumption was associated with obesity and high cholesterol levels. These associations should be further explored in longitudinal studies and population-based strategies should be developed to address these cardiovascular risk factors.

Hospitalized children with SARS-CoV-2 infection and MIS-C in Jamaica: A dive into the first 15 months of the novel pandemic.

Objectives: COVID-19 in children was initially mild until the emergence of Multisystem Inflammatory Syndrome in Children (MIS-C). We describe pediatric COVID-19 in a developing country within the Caribbean. Methods: Jamaican children who were hospitalized with SARS-CoV-2 infection, in one Caribbean regional academic referral center from April 2020 through June 2021 were included. Prospective surveillance and pediatric infectious disease consultations were performed using the CDC's MIS-C case definition. Data were extracted from patients' hospital charts using WHO's reporting form, entered into the RedCap database, and SPSS 28 was used for analysis. MIS-C and non-MIS-C patients were compared using independent sample t-tests for continuous variables and Fisher's exact test for categorical variables, p values < 0.05 were statistically significant. Results: Seventy-nine children with COVID-19 with/without MIS-C presented to UHWI. Thirty-eight (48%) were mild ambulatory cases. Hospitalizations occurred in 41 (52%) children, with median age of 10 1 2 years. SARS-CoV-2 RT-PCR positivity was present in 26 (63%), Immunoglobulin M, or Immunoglobulin G (IgM/IgG) positivity in 8 (20%), with community exposures in 7 (17%). Eighteen (44%) MIS-C positive patients were significantly more likely than 23 MIS-C negative patients (56%) to present with fever (94% vs. 30%; p < 0.001), fatigue/lethargy (41% vs. 4%; p = 0.006), lymphadenopathy (33% vs. 0%; p = 0.003), elevated neutrophils (100% vs. 87%; p = 0.024), and ESR (78% vs. 9%; p = 0.002). Involvement of > two organ systems occurred more frequently in MIS-C positive cases (100% vs. 34%; p < 0.001), including gastrointestinal (72% vs. 17%; p < 0.001); vomiting/nausea (39% vs. 9%; p < 0.028); hematological/coagulopathic (67% vs. 4%; p < 0.001); dermatologic involvement (56% vs. 0%; p < 0.001); and mucositis (28% vs. 0%; p = 0.001). MIS-C patients had Kawasaki syndrome (44%), cardiac involvement (17%), and pleural effusions (17%). MIS-C patients had >4 abnormal inflammatory biomarkers including D-dimers, C-reactive protein, ESR, ferritin, troponins, lactate dehydrogenase, neutrophils, platelets, lymphocytes, and albumen (72%). MIS-C patients were treated with intravenous immune gamma globulin (78%), aspirin (68%), steroids (50%), and non-invasive ventilation (11%). None required inotropes/vasopressors. MIS-C negative patients received standard care. All recovered except one child who was receiving renal replacement therapy and developed myocardial complications. Conclusions: In this first report of COVID-19 from the Caribbean, children and adolescents with and without MIS-C were not very severe. Critical care interventions were minimal and outcomes were excellent.

The Jamaica Salt Consumption Study Protocol: Sodium Intake; Sodium Content in Restaurant Foods; Knowledge, Attitudes, and Practices; Spot Urine Sodium Validation.

Background: Excess dietary salt consumption is a major contributor to hypertension and cardiovascular disease. Public education programs on the dangers of high salt intake, and population level interventions to reduce the salt content in foods are possible strategies to address this problem. In Jamaica, there are limited data on the levels of salt consumption and the population's knowledge and practices with regards to salt consumption. This study therefore aims to obtain baseline data on salt consumption, salt content in foods sold in restaurants, and evaluate knowledge, attitudes, and practices of Jamaicans regarding salt consumption. Methods: The study is divided into four components. Component 1 will be a secondary analysis of data on urinary sodium from spot urine samples collected as part of a national survey, the Jamaica Health and Lifestyle Survey 2016-2017. Component 2 will be a survey of chain and non-chain restaurants in Jamaica, to estimate the sodium content of foods sold in restaurants. Component 3 is another national survey, this time on a sample 1,200 individuals to obtain data on knowledge, attitudes and practices regarding salt consumption and estimation of urinary sodium excretion. Component 4 is a validation study to assess the level of agreement between spot urine sodium estimates and 24-hour urinary sodium from 120 individuals from Component 3. Discussion: This study will provide important baseline data on salt consumption in Jamaica and will fulfil the first components of the World Health Organization SHAKE Technical Package for Salt Reduction. The findings will serve as a guide to Jamaica's Ministry of Health and Wellness in the development of a national salt reduction program. Findings will also inform interventions to promote individual and population level sodium reduction strategies as the country seeks to achieve the national target of a 30% reduction in salt consumption by 2025.

Estudio observacional prospectivo que evalúa la carga de enfermedad del HZ en Colombia / Prospective observational study evaluating the disease burden of HZ in Colombia

Resumen Introducción: el herpes zóster (HZ) es una enfermedad debilitante que afecta negativamente la calidad de vida (CV). Este estudio buscó describir la carga de la enfermedad por el HZ en Colombia. Métodos: estudio prospectivo, observacional, de cohorte única realizado en 10 centros clínicos colombianos. Para ser elegibles, los pacientes tenían que ser inmunocompetentes, ≥50 años de edad, y tener un diagnóstico confirmado de HZ en fase aguda o dolor posherpético. Los resultados del estudio incluyeron el inventario breve del dolor por zóster (ZBPI), la CV evaluada con el cuestionario EQ-5D y la utilización de recursos de atención médica (URAM) debido a HZ. El seguimiento fue de 180 días. Resultados: se incluyeron 154 pacientes con una media (DE) de la edad de 64.6 (9.6) años. La media (DE) del peor dolor agudo fue 8.2 (2.1), mientras la neuralgia posherpética (dolor por HZ ≥3 que persistió ≥90 días) fue reportado por 36.5% de los pacientes. Los predictores significativos del aumento de la carga de dolor fueron la edad avanzada y puntuaciones de peor dolor más altas desde el inicio de la erupción. El aumento en el dolor asociado a HZ estuvo acompañado con reducción significativa en CV, la cual duró aproximadamente 60 días. En términos de la URAM, medicamentos para el HZ y que fueron recetados a 98.7% de los pacientes, incluyendo aciclovir en 85.1% de los pacientes, 79.2% tuvieron un seguimiento por un médico general, 38.2% visitó una sala de emergencia y 29.2% visitó un especialista Conclusión: HZ está asociado a carga de enfermedad significativa en Colombia, incluyendo dolor, impacto en la CV y URAM. A medida que la población colombiana envejece, se deben implementar estrategias para manejar y/o prevenir de manera más efectiva la carga asociada al HZ. (Acta Med Colomb 2021; 46.

Abstract Introduction: herpes zoster (HZ) is a debilitating disease with a negative effect on quality of life (QL). This study sought to describe the burden of disease of HZ in Colombia. Methods: this was a prospective, observational single-cohort study in 10 Colombian clinical centers. To be eligible, patients had to be immunocompetent, ≥50 years old, and have a confirmed diagnosis of acute phase HZ or postherpetic pain. The study outcomes included the Zoster Brief Pain Inventory (ZBPI), QL assessed through the EQ-5D questionnaire, and healthcare resource utilization (HCRU) due to HZ. Patients were followed for 180 days. Results: 154 patients were included with a mean (SD) age of 64.6 (9.6) years. The mean (SD) worst acute pain was 8.2 (2.1), while postherpetic neuralgia (HZ pain ≥3 which lasted for ≥90 days) was reported by 36.5% of the patients. The significant predictors of increased pain burden were advanced age and higher worst pain score from the onset of the rash. Increased HZ-related pain was associated with a significant reduction in QL, which lasted approximately 60 days. In terms of HCRU, HZ medications were prescribed for 98.7% of the patients, including acyclovir in 85.1%; 79.2% were followed by a general practitioner; 38.2% were seen in the emergency room and 29.2% consulted a specialist. Conclusion: HZ is associated with a significant burden of disease in Colombia, including pain and an impact on QL and HCRU. As the Colombian population ages, strategies should be implemented to more effectively manage and/or prevent the HZ-related burden. (Acta Med Colomb 2021; 46.

Results from a cross-sectional, observational study to assess inadequate pain relief in patients with knee and/or hip osteoarthritis in Mexico.

INTRODUCTION AND OBJECTIVES: There is limited data that characterizes osteoarthritis (OA) patients who experience moderate to severe pain despite analgesic treatment in Mexico. In this study, we estimate the real-world prevalence of inadequate pain relief (IPR) among individuals with knee and/or hip OA who have been prescribed analgesic therapy and characterize this patient population for each country separately. MATERIALS AND METHODS: This is a multinational, multi-site, cross-sectional, observational study. Participating physicians enrolled patients over 50 years of age with diagnosed knee and/or hip OA who had been prescribed topical and/or oral pain medication for at least 30 days prior to study visit, extracted data from their medical charts, and collected patient data using established questionnaires. RESULTS: 301 patients treated by 35 physicians in Mexico were enrolled in the study. More than half of the patients (53%) met the definition of IPR. Patients with IPR were significantly older (66.8 vs. 63.5 years, p=0.002) and were more likely to be obese (24.2% vs. 11.9%, p=0.006). Patients in the IPR group were more likely to report moderate/severe problems across all 5 dimensions of the EQ-5D and reported higher scores, indicating worse outcomes, on all three WOMAC subscales. Patients in the IPR group also reported reduced work productivity and greater treatment dissatisfaction compared to patients without IPR. DISCUSSION AND CONCLUSIONS: IPR is highly prevalent among individuals with knee and/or hip OA in Mexico. Patients with IPR experience decreased health-related quality of life HRQoL and work productivity, impaired function, and poor treatment satisfaction. Health care professionals need to be aware of the high prevalence of IPR, work toward improving OA patient management, and facilitate early intervention or changes in drug and other treatment modalities.

The Other Double Bubble Sign: Gastric Parastomal Hernia.

Introduction: A parastomal hernia (PSH) is an abnormal herniation of an intra-abdominal organ or other tissue through an intentionally created fascial defect at an ostomy site. PSHs commonly involve reducible mobile segments of omentum, intra-abdominal fat, and bowel. However, PSHs may rarely involve fixed intra-abdominal organs such as the stomach. Case Description: A 68-year-old female underwent emergent Hartmann procedure for Hinchey III diverticulitis and subsequently developed a large reducible parastomal hernia. She was scheduled for an elective laparoscopic colostomy reversal. Prior to her scheduled reversal, the patient presented to the ED with anorexia, lack of colostomy output, emesis, and pain localized to her left lower quadrant. She was found to have gastric outlet obstruction secondary to herniation of the stomach through the left lower quadrant colostomy site. The patient was admitted and treated conservatively with resolution of her symptoms, but due to the high likelihood of recurrence, the decision was made to proceed with laparoscopic Hartmann colostomy reversal with coloproctostomy and primary closure of the fascia without mesh. Conclusion: The contents of a PSH can become incarcerated causing obstruction, strangulation, necrosis and even perforation over time. Fortunately, in this case, herniation of the stomach was recognized early. The patient underwent repair of the hernia defect in order to prevent recurrence of gastric herniation and its potential detrimental complications. The decision regarding the technical aspects of ostomy reversal in terms of mesh selection require further study. In our case, mesh was not used due to patient-specific factors and comorbidities.

Measuring herpes zoster disease burden in São Paulo, Brazil: a clinico-epidemiological single-center study.

OBJECTIVES: Herpes zoster is characterized by acute neuritis and post-herpetic neuralgia. Currently, data concerning the zoster-associated impact on quality of life and healthcare resource utilization in Brazil are scarce. This study measured the zoster-associated burden in a Brazilian population. METHODS: This was a prospective, observational, single-cohort study conducted in a primary hospital's emergency room in São Paulo, Brazil. Patients enrolled at various timepoints during a zoster episode were followed over 180 days. The Zoster Brief Pain Inventory and the Initial Zoster Impact Questionnaire assessed zoster-associated pain. The EuroQoL assessed the impact of herpes zoster and/or zoster-associated pain on quality of life. Healthcare resource utilization was assessed by patient-reported questionnaires. RESULTS: One-hundred forty-six zoster patients were enrolled [mean (SD) age of 69.9 (10.9) years]. Mean (SD) worst pain scores decreased from 5.3 (3.5) at baseline to 1.9 (3.0) 180 days following rash onset. Mean (SD) EuroQoL scores significantly decreased from 0.9 (0.2) before rash appearance to 0.7 (0.2) after rash onset (p<0.001), followed by gradual improvements in quality of life over 180 days, with pre-herpes zoster quality of life achieved at the end of the observation period. The majority of patients purchased prescription medications (89.7%) and required doctor's office visits (65.8%) for zoster episodes. CONCLUSIONS: Herpes zoster is associated with a significant disease burden, including zoster-associated pain, impaired quality of life and increased healthcare resource utilization in Brazil. These results support the implementation of early intervention and prevention programs such as vaccinations to reduce the herpes zoster-associated disease burden in Brazil.

OBJECTIVES: Herpes zoster is characterized by acute neuritis and post-herpetic neuralgia. Currently, data concerning the zoster-associated impact on quality of life and healthcare resource utilization in Brazil are scarce. This study measured the zoster-associated burden in a Brazilian population. METHODS: This was a prospective, observational, single-cohort study conducted in a primary hospital's emergency room in São Paulo, Brazil. Patients enrolled at various timepoints during a zoster episode were followed over 180 days. The Zoster Brief Pain Inventory and the Initial Zoster Impact Questionnaire assessed zoster-associated pain. The EuroQoL assessed the impact of herpes zoster and/or zoster-associated pain on quality of life. Healthcare resource utilization was assessed by patient-reported questionnaires. RESULTS: One-hundred forty-six zoster patients were enrolled [mean (SD) age of 69.9 (10.9) years]. Mean (SD) worst pain scores decreased from 5.3 (3.5) at baseline to 1.9 (3.0) 180 days following rash onset. Mean (SD) EuroQoL scores significantly decreased from 0.9 (0.2) before rash appearance to 0.7 (0.2) after rash onset (p<0.001), followed by gradual improvements in quality of life over 180 days, with pre-herpes zoster quality of life achieved at the end of the observation period. The majority of patients purchased prescription medications (89.7%) and required doctor's office visits (65.8%) for zoster episodes. CONCLUSIONS: Herpes zoster is associated with a significant disease burden, including zoster-associated pain, impaired quality of life and increased healthcare resource utilization in Brazil. These results support the implementation of early intervention and prevention programs such as vaccinations to reduce the herpes zoster-associated disease burden in Brazil.

Measuring the burden of herpes zoster disease in Costa Rica

AbstractBackground: Herpes zoster is a distressing illness that significantly reduces patients' quality of life. However, Costa Rican data regarding the clinical burden of herpes zoster and associated health care resource utilization is limited. This study aimed to assess the zoster-associated burden evaluating pain, impact on quality of life and health care resource utilization in a Costa Rican sample.Methods:Herpes zoster patients recruited in Costa Rica at a private geriatric practice were enrolled at various time points during a zoster episode and were actively followed over 6 months. Outcomes including zoster-associated pain, quality of life and health care resource utilization were assessed via patient self-reported questionnaires.Results: 50 zoster patients were included [68.0% female, mean (SD) age = 69.5 (10.8) years]. Zoster-associated pain decreased over time while quality of life improved though without full base recovery. The highest health care resource utilization included doctor's office (98.0%), emergency room (60.0%) and specialists (60.0%) visits. Sixteen (32.0%) patients were hospitalized [mean (SD)= 4.3 (4.1) days].Conclusion: Similar to other Latin American countries, high herpes zoster burden was observed in a private geriatric practice in Costa Rica, supporting the need for early intervention and preventive strategies, one of such could be the implementation of a HZ vaccination program.

ResumenJustificación: El herpes zoster es una enfermedad estresante que reduce significativamente la calidad de vida de los pacientes. Sin embargo, datos relativos a la carga clínica de herpes zoster y la utilización de recursos de salud son limitados en Costa Rica. El objetivo de este estudio fue evaluar la carga asociada al herpes zoster evaluando dolor, impacto sobre la calidad de vida y utilización de recursos de salud en una muestra costarricense.Métodos:Pacientes con herpes zoster fueron reclutados en una práctica geriátrica privada en diferentes etapas de un episodio de zoster y fueron activamente seguidos durante 6 meses. Se evaluaron los resultados en el paciente, incluyendo el dolor asociado a zoster, calidad de vida y utilización de recursos de salud mediante cuestionarios autoadministrados.Resultados: Se incluyeron 50 pacientes con herpes zoster [68,0% mujeres, media de edad (SD) = 69.5 (10.8) años]. El dolor asociado a zoster disminuyó con el tiempo mientras que calidad de vida mejoró, aunque sin plena recuperación comparado con la calidad de vida inicial. La utilización de recursos de salud más alta fue visitas al consultorio (98.0%), visitas a sala de urgencias (60.0%) y visitas a especialistas (60.0%). Dieciséis pacientes (32.0%) fueron hospitalizados [media (SD) = 4.3 (4.1) días].Conclusión: Similar a otros países de América Latina, se observó una alta carga de enfermedad debido a herpes zoster en una práctica privada geriátrica en Costa Rica, lo cual respalda la necesidad de la intervención temprana y uso de estrategias preventivas, una de las cuales podría ser la implementación de un programa de vacunación a herpes zoster.

Chikungunya: important lessons from the Jamaican experience.

OBJECTIVES: To describe the clinical presentation of chikungunya virus (CHIKV) illness in adults during the 2014 outbreak in Jamaica and to determine the predictive value of the case definition. METHODS: A cross-sectional study was conducted using clinical data from suspected cases of CHIKV that were reported to the Ministry of Health in April - December 2014. In addition, charts were reviewed of all individuals over 15 years of age with suspected CHIKV based on a diagnosis of CHIKV or "acute viral illness" that presented to four major health centers in Jamaica during the week prior to and the peak week of the epidemic. Data abstracted from these charts using a modified CHIKV Case Investigation Form included demographics, clinical findings, and laboratory tests. RESULTS: In 2014, the Ministry of Health of Jamaica received 4 447 notifications of CHIKV infection. PCR testing was conducted on 137 suspected CHIKV cases (56 men and 81 women; median age 28 years) and was positive for 89 (65%) persons. In all, 205 health charts were identified that met the selection criteria (51 men and 154 women, median age 43 years). The most commonly reported symptoms were arthralgia (86%) and fever (76%). Of those who met the epidemiologic case definition for CHIKV as defined by the Pan American Health Organization, only 34% had this diagnosis recorded. Acute viral illness was the most frequently recorded diagnosis (n = 79; 58%). CONCLUSIONS: Broader case definitions for acute CHIKV illness may be needed to identify suspected cases during an outbreak. Standardized data collection forms and validation of case definitions may be useful for future outbreaks.

Objetivo. Describir el cuadro clínico de la infección por el virus del chikungunya (CHIKV) en los adultos durante el brote del 2014 en Jamaica y determinar el valor predictivo de la definición de caso. Métodos. Se realizó un estudio transversal con los datos clínicos de los presuntos casos de CHIKV que se notificaron al Ministerio de Salud entre abril y diciembre del 2014. Además, se examinaron las historias clínicas de todos los mayores de 15 años con presunto cuadro de CHIKV, es decir con diagnóstico de CHIKV o de “virosis aguda”, que acudieron a cuatro grandes centros de salud de Jamaica durante la semana de máxima incidencia de la epidemia y la semana anterior. De las historias se extrajo, mediante un formulario modificado para el estudio de casos de CHIKV, la siguiente información: datos demográficos, resultados clínicos y análisis de laboratorio. Resultados. En el 2014, el Ministerio de Salud de Jamaica recibió 4 447 notificaciones de infección por el CHIKV. Se realizó la RCP de 137 presuntos casos de CHIKV (56 varones y 81 mujeres; mediana de edad de 28 años), que dio positivo en 89 personas (el 65%). En total, se encontraron 205 historias clínicas que reunían los criterios de selección (51 varones y 154 mujeres; mediana de edad de 43 años). Los síntomas comunicados con mayor frecuencia fueron las artralgias (86%) y la fiebre (76%). De los que se ajustaron a la definición epidemiológica de caso de CHIKV de la Organización Panamericana de la Salud, solo en el 34% se había registrado ese diagnóstico. La virosis aguda fue el diagnóstico registrado con mayor frecuencia (n = 79; 58%). Conclusiones. Es posible que se necesiten definiciones de caso más amplias para la infección aguda por CHIKV a fin de identificar los casos sospechosos durante un brote. Los formularios estandarizados para la recopilación de datos y la validación de las definiciones quizá resulten útiles para otros brotes en el futuro.

Dolor, calidad de vida relacionada con la salud y utilización de servicios médicos asociados al herpes zoster en Argentina / Herpes zoster-associated pain, health-related quality of life, and healthcare utilization in Argentina

El herpes zoster (HZ) es causado por reactivación del virus varicela-zoster latente. Se caracteriza por exantema vesicular unilateral, neuri-tis aguda y neuralgia posherpética. Aún hay escasos datos sobre el do-lor asociado al HZ (DAZ), su repercusión en la calidad de vida (CdV) y la utilización de recursos sanitarios (URS) asociada en Argentina. En este estudio prospectivo, observacio-nal, de una cohorte, realizado en 3 centros argenti-nos se valuó la carga de morbilidad asociada al HZ en Argentina en contextos clínicos reales. Los pa-cientes fueron enrolados en diversos momentos du-rante un episodio herpético, y seguidos activamen-te los días 14, 21, 30, 60, 90, 120, 150 y 180. Hubo 96 enrolados(edad 70±10,7 años; tiempo desde el inicio del exantema 16±16,9 días[media±DE]). El puntaje del peor dolor (media±DE) disminuyó de 5,5±3,1 en el enrolamiento a 0,2±0,7 a los 180 días de seguimiento. El puntaje del cuestionario de cali-dad de vida EQ-5D (media±DE) disminuyó significa-tivamente de 0,8±0,1 antes del inicio del exantema a 0,6±0,2 tras su inicio (P<0,001), con mejoría gra-dual de la CdV durante 180 días (0,9±0,1), hasta un puntaje similar al previo al inicio del exantema. La URS más frecuente fueron visitas al consultorio mé-dico (96,9%). La gran mayoría de pacientes compró medicamentos recetados (95,8%) y de venta sin receta (83,3%) para los episodios herpéticos. El DAZ estuvo asociado a gran carga de morbili-dad, deterioro de CdV, aumento de URS y costos asociados en Argenti-na. Esto subraya la importancia de estrategias de intervención precoz o prevención para disminuir la carga de morbilidad asociada al HZ

Herpes zoster (HZ) is caused by re-activation of latent varicella zoster virus and is characterized by unilateral, vesicular cutaneous eruptions, acute neuritis, and post-herpetic neuralgia. To date, data on HZ associated pain (ZAP) and its impact on quality of life (QoL) and associated healthcare resource utilization use (HCRU) in Argentina is scarce. This study assessed the burden of illness associated with HZ in Argentina in a real-life clinical setting. This was a prospective, observational, single-cohort study conducted in 3 sites across Argentina. Patients were enrolled at various time points during the course of a zoster episode and were actively followed on days 14, 21, 30, 60, 90, 120, 150, and 180. There were 96 HZ patients enrolled with a mean±SD age and time since rash onset of 70±10. 7 years and 16±16. 9 days, respectively. Mean±SD worst pain score decreased from 5. 5±3. 1 at enrollment to 0. 2±0.7 at 180 days of follow-up. The mean±SD EQ-5D score significantly decreased from 0. 8±0. 1 before rash onset to 0. 6±0. 2 after rash onset (P <0.001) followed by gradual improvement in QoL over 180 days (0. 9±0.) reaching a similar score to that prior to rash onset. The most common HCRU was visits to the doctor's office with 96.9%. The vast majority of patients purchased prescription medications (95.8%) and over-the-counter medications (83.3%) for HZ episodes. ZAP was found to be associated with severe burden of illness, impaired QoL, increased HCRU, and associated cost in Argentina; highlighting the importance of early intervention or prevention strategies to reduce HZ-associated disease burden

Predictors of postherpetic neuralgia in patients with herpes zoster: a pooled analysis of prospective cohort studies from North and Latin America and Asia.

OBJECTIVES: The most common complication of herpes zoster (HZ) is postherpetic neuralgia (PHN), a persistent pain that can substantially affect quality of life (QoL). This analysis aimed to evaluate predictors of PHN in HZ patients. METHODS: A pooled analysis of prospective cohort studies of HZ patients aged ≥ 50 years from North America (Canada), Latin America (Brazil, Mexico, and Argentina), and Asia (Taiwan, South Korea, and Thailand) was performed. Patients within 14 days of rash onset were included. The incidence of PHN was defined as a worst pain score of ≥ 3, persisting/appearing at >90 days after rash onset. Socio-demographics, HZ disease characteristics, treatment, pain-related interference with activities of daily living, and health-related QoL were assessed. RESULTS: Of 702 patients with HZ, 148 (21.1%) developed PHN. Similar risks of PHN were observed across geographic regions. On multivariate analysis, older age, greater severity of pain at rash onset, employment status, walking problems at enrollment, and pain interference affecting social relationships were significantly associated with the development of PHN. CONCLUSIONS: In addition to older age and severe acute pain, this study suggests that impaired physical and social functioning from acute zoster pain may play a role in the development of PHN in this prospective cohort study of HZ patients from North and Latin America and Asia.

Magnitude, distribution, and estimated level of underreporting of acute gastroenteritis in Jamaica.

Jamaica is the third largest island in the Caribbean. The epidemiology of acute gastroenteritis (AGE) is important to Jamaica, particularly in the areas of health, tourism, and because of the potential impact on the local workforce and the economy. Data collected by the National Surveillance Unit on the prevalence of AGE transmitted by food are not accurate. To determine the true magnitude, risk factors, and the extent of underreporting of AGE in Jamaica, we conducted a cross-sectional, population-based retrospective survey during the periods of 21 February-7 March and 14-27 June 2009, corresponding to high- and low-AGE season respectively. Of the total 1,920 persons selected randomly by a multistage cluster-sampling process, 1,264 responded (response rate 65.8%). Trained interviewers administered a standardized, validated questionnaire during face-to-face interviews. The overall prevalence of self-reported AGE was 4.0% (95% CI 2.9-5.1) at a rate of 0.5 episodes/per person-year. The highest monthly prevalence of AGE (14.6%) was found among the 1-4 year(s) age-group and the lowest (2.1%) among the 25-44 years age-group. Of the 18 cases (36%) who sought medical care, 11% were hospitalized, 33% were treated with antibiotics, and 66.7% received oral rehydration fluids. Only 2 cases who sought medical care reportedly submitted stool specimens. The mean duration of diarrhoea was 3.1 days, which resulted in a mean loss of 4 productive days, with over half of the cases requiring someone to care for them. The burden of syndromic AGE for 2009 was extrapolated to be 122,711 cases, showing an underreporting factor of 58.9. For every laboratory-confirmed AGE case, it was estimated that 383 more cases were occurring in the population. This research confirms that the prevalence of AGE is underreported in Jamaica and not being adequately detected by the current surveillance system. The components of the integrated surveillance system for AGE in Jamaica, particularly the laboratory aspect, need to be strengthened.

Prevalence of craniorachischisis in a Texas-Mexico border population.

BACKGROUND: The most severe neural tube defect (NTD), craniorachischisis, is characterized by anencephaly confluent with spina bifida open from the cervical to the lumbar region. We describe the prevalence of craniorachischisis among the Texas-Mexico border population during the period 1993-1999. METHODS: An active surveillance system identified all clinically apparent NTD-affected fetuses and infants born to mothers residing and delivering in any of the 14 Texas-Mexico border counties. Craniorachischisis cases included live-born, stillborn, and therapeutic abortions. RESULTS: A total of 16 craniorachischisis cases were identified for a total prevalence of 0.51 per 10,000 live births (Mexican American prevalence, 0.52 per 10,000) and a prevalence of 0.28 per 10,000 live births for cases of 20 weeks gestation or greater. CONCLUSIONS: The prevalence of craniorachischisis was higher than that reported in Atlanta (0.1 per 10,000 live births), but much lower than that reported in Northern China (10.7 per 10,000 births). In this high NTD prevalence region, it is possible that a multiplicity of risk factors, mostly related to poverty, contribute to a high prevalence of craniorachischisis.
