The association between sociodemographic characteristics, clinical indicators and body mass index in a population at risk of type 2 diabetes: A cross-sectional study in two Colombian cities.

AIMS: To assess the association between sociodemographic and clinical factors with body mass index (BMI) in a population at risk of type 2 diabetes (T2D) in Bogotá and Barranquilla, Colombia. METHODS: This cross-sectional study used data from the PREDICOL Study. Participants with a FINDRISC ≥ 12 who underwent an Oral Glucose Tolerance Test (OGTT) were included in the study (n=1166). The final analytical sample size was 1101 participants. Those with missing data were excluded from the analysis (n=65). The main outcome was body mass index (BMI), which was categorized as normal, overweight, and obese. We utilized unadjusted and adjusted ordinal logistic regression analysis to calculate odds ratios (OR) and 95 % confidence intervals (CI). RESULTS: The prevalence of overweight and obesity was 41 % (n=449) and 47 % (n=517), respectively. Participants with a 2-hour glucose ≥139 mg/dl had 1.71 times higher odds of being overweight or obese (regarding normal weight) than participants with normal 2-hour glucose values. In addition, being a woman, waist circumference altered, and blood pressure >120/80 mmHg were statistically significantly associated with a higher BMI. CONCLUSION: Strategies to control glycemia, blood pressure, and central adiposity are needed in people at risk of T2D. Future studies should be considered with a territorial and gender focus, considering behavioral, and sociocultural patterns.

The Impact of Health Inequities on Population-Based Breast Cancer Survival in a Colombian Population, 2008-2015.

OBJECTIVE: To obtain breast cancer survival estimates in Manizales, Colombia, considering socioeconomic level, health insurance regime and residential area, while adjusting for age, histology and stage at diagnosis. METHODS: Analytical cohort study based on breast cancer incident cases recorded by the Population-based Manizales Cancer Registry between 2008-2015. Patients were followed-up for 60 months. Cause-specific survival was calculated using the Kaplan-Meier method for variables of interest, with the Wilcoxon-Breslow-Gehan test for differences. Cox multivariate regression models were fitted. RESULTS: 856 breast cancer cases were included. The 5-year cause-specific survival for the entire cohort was 78.2%. It was higher in women with special/exception health insurance, high socioeconomic level, <50 years old, ductal carcinoma, and stages I and II. Residential area did not impact survival. In Cox models, the subsidized health insurance regime (HR: 4.87 vs contributory) and low socioeconomic level (HR: 2.45 vs high) were predictors of the hazard of death in women with breast cancer, adjusted for age, histology, stage and interactions age-stage and insurance-stage. A positive interaction (synergistic effect modification) between health insurance regime and stage regarding to survival was observed. CONCLUSION: Socioeconomic factors significantly contribute to the inequities in breast cancer survival, independent of the stage at diagnosis. This suggests the need for comprehensive interventions to remove barriers to accessing the health system. This research provides evidence of survival gaps mediated by certain social determinants of health and generates data on the overall performance of the Colombian health system.

High levels of cardiovascular biomarkers in fatal Chikungunya virus infection.

Chikungunya virus (CHIKV) infection is an emerging arboviral disease that has spread geographically to many previously unaffected areas. Although severe cases of acute CHIKV infection have been documented, little is known about its pathogenesis. We aimed to determine the levels of cardiovascular biomarkers in fatal and non-fatal patients with acute CHIKV infection. This study included fatal and non-fatal patients with CHIKV reported to National System for Public Health Surveillance and laboratory-confirmed by the Colombian National Institute of Health. Each fatal patient was matched to 2 non-fatal patients for age (± 10 years). Blood samples were processed for cardiovascular biomarkers by multiplex immunoassays. Twenty-five cases of fatal CHIKV infection and 50 patients of non-fatal CHIKV infection were included. Nearly 20% of the population were under 10 years old and 52% were over 60. The median serum levels of endocan-1 (p = 0.000), creatine kinase MB isoenzyme (p = 0.000), oncostatin (p = 0.000), fatty-acid-binding protein 3 (p = 0.000) and fatty-acid-binding protein 4 (p = 0.000) were significantly higher in fatal CHIKV infection cases than in non-fatal patients. Troponin I tended to be higher in fatal CHIKV infection cases than in non-fatal CHIKV infection patients (p = 0.063). Among fatal patients, no significant differences were found in serum levels of cardiovascular biomarkers among younger (< 50 years-old) and older (≥ 50 years-old) patients. We found high serum levels of cardiovascular biomarkers in fatal CHIKV infection. These results promote the fact that endothelial and cardiac damage can occurs and may be significant factors related organ failure and death in these patients.

Risk of violence from a current or former partner: Associated factors and classification in a nationwide study in Colombia.

Intimate partner violence (IPV) includes assaults that risk a woman's bodily integrity. Intimate partners commit IPV, people with whom the victim shares (or shared) a close personal or sexual relationship. This phenomenon has a great global and national impact. Thus, it is necessary to establish trends of the risk of physical violence to women by their current or former partner in each department of Colombia and its relationship with sociodemographic and health characteristics. This study uses an ecological approach at the departmental level, with victims of intimate partner violence treated at the National Institute of Legal Medicine and Forensic Sciences (INMLyCF). Potential factors were identified through Bayesian factor analysis and were included in the model to estimate risk. The findings show that the Casanare department had the highest risk of producing victims (SMR: 2.545). In departments where the educational level of women is at or below primary school, there is a high-risk ß = 0.343 (0.285, 0.397) of them being assaulted. For the departments in which the employment of women is in sales and services or office workers, the associated factor presents a higher risk ß = 0.361 (0.201, 0.485), as in the risk related to affiliation with the social security system ß = 0.338 (0.246, 0.498), as well as sexual and reproductive life ß = 0.143 (0.003, 0.322). The following categories were associated with physical gender violence: no education and low participation in making purchases at home ß = 0.106 (0.049, 0.199), low participation in decisions about their health, and visits to family and friends ß = 0.240 (0.170, 0.299). Therefore, public health programs should strengthen women's empowerment in household decisions and increase their educational level to reduce this incidence.

Seroprevalence of anti-SARS-CoV-2 antibodies in Colombia, 2020: A population-based study.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to cause very high morbidity and mortality throughout Latin American countries. However, few population-based seroprevalence surveys have been conducted to quantify attack rates and characterize drivers of transmission. METHODS: We conducted a population-based cross-sectional study to assess the seroprevalence of antibodies against SARS-CoV-2 in ten cities in Colombia between September and December 2020. The study involved multi-stage cluster sampling at each city. Participants provided a serum sample and answered a demographic and risk factor questionnaire. Prior infection by SARS-CoV-2 was ascertained using the "SARS-CoV-2 Total (COV2T) Advia Centaur - Siemens" chemiluminescence assay. FINDINGS: A total of 17863 participants from 7320 households participated in the study. Seroprevalence varied substantially between cities, ranging from 26% (95%CI 23-29 %) in Medellín to 68% (95%CI 62-74 %) in Guapi. There were no differences in seroprevalence by sex, but seropositivity was higher in certain ethnic groups. There was substantial heterogeneity in seroprevalence within cities, driven to a large extent by a strong association between socioeconomic stratum and seropositivity. INTERPRETATION: Colombia has been one of the Latin American countries most affected by the COVID-19 pandemic. This study documented very high attack rates in several Colombian cities by the end of 2020 and identified key drivers of heterogeneities including ethnicity and socioeconomic stratum. Few studies of seroprevalence of SARS-CoV-2 have been conducted in Latin America, and therefore this study contributes to the fundamental understanding of the pandemic in the region. FUNDING: The study was sponsored by, Ministerio de Ciencia y Tecnología e Innovación -CT361/2020, Ministerio de Salud y Protección Social, Fundación Universitaria del Norte, Imperial College of London, Universidad Nacional de Colombia (Sede Medellín), Universidad de Córdoba, California University, Unidad Nacional de Gestión del Riesgo, Centro de Atención y Diagnóstico de Enfermedades Infecciosas -CDI-, Centro Internacional de Entrenamiento e Investigaciones Médicas -CIDEIM-, Departamento Administrativo Nacional de Estadística - DANE, Fondo Nacional de Turismo -FONTUR-, Secretarías de Salud Departamentales, Distritales y Municipales and Instituto Nacional de Salud.

Prospective, Multicenter, Controlled Trial of Mobile Stroke Units.

BACKGROUND: Mobile stroke units (MSUs) are ambulances with staff and a computed tomographic scanner that may enable faster treatment with tissue plasminogen activator (t-PA) than standard management by emergency medical services (EMS). Whether and how much MSUs alter outcomes has not been extensively studied. METHODS: In an observational, prospective, multicenter, alternating-week trial, we assessed outcomes from MSU or EMS management within 4.5 hours after onset of acute stroke symptoms. The primary outcome was the score on the utility-weighted modified Rankin scale (range, 0 to 1, with higher scores indicating better outcomes according to a patient value system, derived from scores on the modified Rankin scale of 0 to 6, with higher scores indicating more disability). The main analysis involved dichotomized scores on the utility-weighted modified Rankin scale (≥0.91 or <0.91, approximating scores on the modified Rankin scale of ≤1 or >1) at 90 days in patients eligible for t-PA. Analyses were also performed in all enrolled patients. RESULTS: We enrolled 1515 patients, of whom 1047 were eligible to receive t-PA; 617 received care by MSU and 430 by EMS. The median time from onset of stroke to administration of t-PA was 72 minutes in the MSU group and 108 minutes in the EMS group. Of patients eligible for t-PA, 97.1% in the MSU group received t-PA, as compared with 79.5% in the EMS group. The mean score on the utility-weighted modified Rankin scale at 90 days in patients eligible for t-PA was 0.72 in the MSU group and 0.66 in the EMS group (adjusted odds ratio for a score of ≥0.91, 2.43; 95% confidence interval [CI], 1.75 to 3.36; P<0.001). Among the patients eligible for t-PA, 55.0% in the MSU group and 44.4% in the EMS group had a score of 0 or 1 on the modified Rankin scale at 90 days. Among all enrolled patients, the mean score on the utility-weighted modified Rankin scale at discharge was 0.57 in the MSU group and 0.51 in the EMS group (adjusted odds ratio for a score of ≥0.91, 1.82; 95% CI, 1.39 to 2.37; P<0.001). Secondary clinical outcomes generally favored MSUs. Mortality at 90 days was 8.9% in the MSU group and 11.9% in the EMS group. CONCLUSIONS: In patients with acute stroke who were eligible for t-PA, utility-weighted disability outcomes at 90 days were better with MSUs than with EMS.

Neonatal late-onset infection with SARS CoV-2 / [Sepsis neonatal tardía por SARS CoV-2].

During the SARS COV-2 pandemic, the vast majority of infected patients are showing symptoms related to lung damage. At pediatric ages, especially newborns, symptoms from other organ systems without respiratory illness could make COVID-19 hard to diagnose. We are reporting three cases of newborns who were attended in the course of the mitigation phase in the emergency service of a maternal hospital in Barranquilla, Colombia, for high temperature and general compromised condition. During their clinical course, they developed gastrointestinal symptoms without showing any respiratory manifestations. They were not epidemiologically linked to a contact suspected to be a COVID-19 case and their mothers had had no respiratory symptoms since the public health emergency in our country was declared 45 days before. The absence of clinical respiratory manifestations in this group of patients with COVID-19 should draw clinicians' attention to the need to suspect SARS CoV-2 infection in febrile newborns.

Durante la pandemia por SARS CoV-2 la gran mayoría de pacientes ha presentado afectación pulmonar como síntoma cardinal. En los niños, especialmente en recién nacidos, la sintomatología debida al efecto en otros sistemas diferentes al respiratorio puede dificultar el diagnóstico. Se reportan tres casos de recién nacidos atendidos durante la fase de mitigación de la pandemia por SARS CoV-2 en el servicio de urgencias de un hospital materno-infantil en Barranquilla, Colombia, por presentar cuadros febriles que afectaban su estado general. En su evolución clínica predominó la sintomatología gastrointestinal sin que desarrollaran nunca manifestaciones respiratorias. La investigación epidemiológica no evidenció contacto con casos sospechosos o positivos para COVID-19. Sus madres no habían tenido síntomas respiratorios en los 45 días transcurridos desde la declaración de la emergencia en salud pública en el país. La ausencia de manifestaciones clínicas respiratorias en este grupo de pacientes con COVID-19 debe llamar la atención de los clínicos sobre la necesidad de sospechar la infección por SARS CoV-2 en recién nacidos con estados febriles.

[Prevalence of lymph node involvement in patients with endometrial cancer, Colombia 2009-2016: Exploratory analysis of associated factors].

OBJECTIVE: To determine the prevalence of lymph node involvement in patients with endometrial cancer and to explore factors associated with lymph node invasion. METHODS: Prevalence study with exploratory analysis. The study included patients with endometrial cancer who underwent total abdominal hysterectomy plus bilateral salpyingooophorectomy and pelvic lymphadenectomy with or without para-aortic lymphadenectomy in seven oncology centers in Colombia between 2009 and 2016. Patients who had received prior radiotherapy or chemotherapy, with a histological diagnosis of neuroendocrine tumors, carcinosarcomas or synchronous or metachronous lesions were excluded. Non-probabilistic sampling. Sample size n=290. Measured variables: sociodemographic, clinical and histopathological, and pelvic or para-aortic lymph node involvement. The prevalence for the period is presented. The exploratory analysis was conducted using crude odds ratio (OR) and adjusted OR by means of a multivariate model (unconditional logistic regression). RESULTS: Overall, 467 cases were retrieved. Of them, 163 were excluded because of non-availability of all the variables. In total, 304 patients were studied. The prevalence of lymph node involvement was 15.8 % (48/304). In the crude and adjusted analysis, factors associated with lymph node involvement were lymphovascular invasion (adjusted OR: 9.32; 95 % CI 4.27-21.15) and myometrial invasion (adjusted OR: 3.95; 95 % CI 1.29-14.98). CONCLUSIONS: Of the patients undergoing lymphadenectomy, 15 % have lymph node involvement. Less invasive diagnostic options than radical surgery to ascertain lymph node invasion should be assessed.

Los factores asociados al compromiso ganglionar en el análisis crudo y ajustado fueron la invasión linfovascular (OR ajustado = 9,32; IC 95 %: 4,27-21,15) e invasión miometrial (OR ajustado = 3.95; IC 95 %: 1,29-14,98). CONCLUSIONES: El 15 % de las pacientes sometidas a linfadenectomía tienen compromiso ganglionar. Se deben evaluar alternativas diagnósticas menos invasivas que la cirugía radical para establecer la invasión ganglionar.

Chikungunya outbreak (2015) in the Colombian Caribbean: Latent classes and gender differences in virus infection.

Chikungunya virus (CHIKV), a mosquito-borne alphavirus of the Togaviridae family, is part of a group of emergent diseases, including arbovirus, constituting an increasing public health problem in tropical areas worldwide. CHIKV causes a severe and debilitating disease with high morbidity. The first Colombian autochthonous case was reported in the Colombian Caribbean region in September 2014. Within the next two to three months, the CHIKV outbreak reached its peak. Although the CHIKV pattern of clinical symptomatology has been documented in different epidemiological studies, understanding of the relationship between clinical symptomatology and variation in phenotypic response to CHIKV infection in humans remains limited. We performed a cross sectional study following 1160 individuals clinically diagnosed with CHIKV at the peak of the Chikungunya outbreak in the Colombian Caribbean region. We examined the relationship between symptomatology and diverse phenotypic responses. Latent Class Cluster Analysis (LCCA) models were used to characterize patients' symptomatology and further identify subgroups of individuals with differential phenotypic response. We found that most individuals presented fever (94.4%), headache (73.28%) and general discomfort (59.4%), which are distinct clinical symptoms of a viral infection. Furthermore, 11/26 (43.2%) of the categorized symptoms were more frequent in women than in men. LCCA disclosed seven distinctive phenotypic response profiles in this population of CHIKV infected individuals. Interestingly, 282 (24.3%) individuals exhibited a lower symptomatic "extreme" phenotype and 74 (6.4%) patients were within the severe complex "extreme" phenotype. Although clinical symptomatology may be diverse, there are distinct symptoms or group of symptoms that can be correlated with differential phenotypic response and perhaps susceptibility to CHIKV infection, especially in the female population. This suggests that, comparatively to men, women are a CHIKV at-risk population. Further study is needed to validate these results and determine whether the distinct LCCA profiles are a result of the immune response or a mixture of genetic, lifestyle and environmental factors. Our findings could contribute to the development of machine learning approaches to characterizing CHIKV infection in other populations. Preliminary results have shown prediction models achieving up to 92% accuracy overall, with substantial sensitivity, specificity and accuracy values per LCCA-derived cluster.

Polimorfismos de los genes del sistema leptina-melanocortina asociados con la obesidad en la población adulta de Barranquilla / Polymorphisms of leptin-melanocortin system genes associated with obesity in an adult population from Barranquilla

Introducción. La obesidad se considera un grave problema de salud pública y por ello se hacen esfuerzos en la búsqueda de genes como el LEP, el LEPR y el MC4R del sistema leptina-melanocortina, el cual opera en la regulación neuroendocrina de la ingestión y el equilibrio energético e influye en la patogenia de la enfermedad. Los resultados contradictorios en torno a la asociación de estos genes con la obesidad plantean la necesidad de nuevas investigaciones. Objetivo. Analizar los polimorfismos rs2167270 del gen LEP, rs1137101 del gen LEPR y rs17782313 del gen MC4R asociados con la obesidad y sus variables clínicas y bioquímicas en una muestra de pacientes adultos de Barranquilla. Materiales y métodos. Se estudiaron 111 personas obesas y 155 no obesas como controles. Los polimorfismos se determinaron mediante reacción en cadena de la polimerasa (PCR) en tiempo real. Se tomaron las medidas antropométricas, se evaluó la presión arterial y se hicieron pruebas bioquímicas. Resultados. No se encontraron diferencias estadísticas en la frecuencia alélica y genotípica de los polimorfismos en los grupos estudiados. En cuanto a las variables clínicas y bioquímicas, el genotipo CC del polimorfismo rs17782313 del gen MC4R, se asoció con un aumento de la presión arterial sistólica y, el alelo T y su genotipo homocigoto, con una disminución del colesterol HDL en los obesos. No se evidenció ningún efecto de los otros polimorfismos en estas variables. Conclusiones. Los polimorfismos rs2167270 del gen LEP, rs1137101 del gen LEPR y rs17782313 del gen MC4R, no se asociaron con obesidad en la población analizada. Se encontró que el polimorfismo rs17782313 del gen MC4R influyó en el aumento de la presión arterial sistólica y la disminución del colesterol HDL en las personas obesas.

Introduction: Obesity is considered a serious public health problem. Efforts have been directed to search for candidate genes such as LEP, LEPR, and MC4R involved in the leptin- melanocortin system. The neuroendocrine regulation of these genes on energy intake and balance influences the pathogenesis of this disease. Contradictory results regarding the association of these genes with obesity raise the need for new research. Objective: To analyze the association between obesity and LEP rs2167270, LEPR rs1137101, and MC4R rs17782313 polymorphisms and the clinical and biochemical variables in obese adults from Barranquilla, Colombia. Materials and methods: We analyzed 111 obese adults and 155 non-obese individuals as controls. The polymorphisms were determined by real-time PCR. Besides, anthropometric measures, blood pressure, and biochemical tests were evaluated. Results: No statistical differences were found in allele and genotype frequencies of gene polymorphisms between groups. The CC genotype of MC4R rs17782313 polymorphism was associated with increased systolic blood pressure and T allele and TT genotype, with decreased HDL cholesterol in obese adults. The effect of the other polymorphisms on these variables was not evidenced. Conclusions: LEP rs2167270, LEPR rs1137101, and MC4R rs17782313 polymorphisms were not associated with obesity in the population under study. MC4R rs17782313 polymorphisms were associated with an increase in systolic blood pressure and a decrease in HDL cholesterol.

Spatial distribution of the relative risk of Zika virus disease in Colombia during the 2015-2016 epidemic from a Bayesian approach.

OBJECTIVE: To determine the spatial distribution of the risk of Zika virus disease in each region of Colombia during the 2015-2016 epidemic. METHODS: An ecological study was designed to estimate the risks for each Colombian region using first-order neighbors, covariate effects, and three adjacent periods of time (beginning, development, and end of the epidemic) to analyze the spatial distribution of the disease based on a Bayesian hierarchical model. RESULTS: Spatial distribution of the estimated risks of Zika virus disease showed that it increased in a strip that crosses the central area of the country from west to east. Analysis of the three time periods showed greater risk of the disease in the central and southern zones-Arauca and Santander-where the increase in risk was four times higher during the peak phase compared with the initial phase of the outbreak. CONCLUSION: In the identified high-risk areas, integrated surveillance systems for Zika virus disease and its complications must be strengthened to provide up-to-date and accurate epidemiological information. This information would allow those involved in policy and decision making to identify new outbreaks and risk clusters, enabling more focused and accurate measures to target at-risk populations.

Enfermedades crónicas no transmisibles prioritarias en la Región Caribe Colombiana en el periodo 2008-2015: un análisis de la mortalidad / Chronic noncommunicable diseases priority in the Colombian Caribbean Region in the period 2008-2015: An analysis of mortality

RESUMEN Objetivo: Estimar el riesgo de muerte por enfermedades crónicas no transmisibles prioritarias en la región Caribe colombiana en el periodo 2008-2015. Materiales y métodos: Mediante un estudio ecológico se analizaron los datos de mortalidad disponibles en el Departamento Administrativo Nacional de Estadística (DANE). Con el ajuste de las tasas de mortalidad mediante razones estandarizadas de mortalidad (REM) por edad y sexo y mediante un modelo bayesiano, se estimó el riesgo suavizado de morir por causa de las enfermedades priorizadas. Se valoró su evolución temporal con tasas ajustadas anuales de mortalidad. Resultados: De 2008 a 2015 ocurrieron 148.331 muertes, de las cuales 76 201 (51,4 %) ocurrieron en hombres. El 58.1 % (86 185 muertes) corresponden a trastornos en el sistema circulatorio, seguido de los tumores malignos con un 24.4 % (36 188 muertes). Las enfermedades isquémicas del corazón ocupan el primer lugar en las causas de muerte, con un aumento significativo (p<0,001) del riesgo a partir de 2011, al igual que la tendencia en neoplasias de próstata (p<0,001) y mama en mujeres (p=0,022). Conclusión: La mortalidad debida a las enfermedades crónicas no transmisibles estudiadas aumentó en la región en el período 2008-2015. Con una mayor tendencia en el riesgo en los hombres para la mayoría de las enfermedades, lo que genera información relevante para que los tomadores de decisiones en salud ajusten los programas y servicios de prevención de la enfermedad, promoción, atención y rehabilitación en salud acorde a la realidad del ente territorial.

ABSTRACT Objective: To estimate the risk of mortality due to Chroic noncommunicable diseases priority in the Colombian Caribbean region using Bayesian methods for the 2008-2015 period. Instruments and methods: Through an ecological study, the mortality data available in the National Administrative Department of Statistics (DANE) database was analyzed. Adjusting the mortality rates using standardized mortality ratios (REM) by age and gender and using a Bayesian model, the smoothed risk of dying due to prioritized diseases was estimated. Its temporal evolution was assessed with annual adjusted mortality rates. Results: For the 2008 - 2015 period, 148,331 people died, 76 201 (51.4 %) of which were men. 58.1 % (86 185 deaths) correspond to disorders in the circulatory system, followed by malignant tumors with 24.4 % (36 188 deaths). Ischemic heart diseases occupy the first place in the causes of death with a significant increase (p<0,001) of risk as of 2011, likewise for prostate neoplasms (p<0,001) and breast neoplasms in women (p=0,022). Conclusion: Mortality due to the observed chronic noncommunicable diseases increased in the region during the 2008-2015 period. There is a greater tendency of risk for men for the majority of the diseases which generates relevant information so that the decisión makers in healthcare adjust the programs and services of disease prevention, promotion, attention and rehabilitation according to the reality of the territorial entity.

Long-term outcomes of Guillain-Barré syndrome possibly associated with Zika virus infection.

BACKGROUND: This prospective cohort investigation analyzed the long-term functional and neurologic outcomes of patients with Zika virus-associated Guillain-Barré syndrome (GBS) in Barranquilla, Colombia. METHODS: Thirty-four Zika virus-associated GBS cases were assessed a median of 17 months following acute GBS illness. We assessed demographics, results of Overall Disability Sum Scores (ODSS), Hughes Disability Score (HDS), Zung Depression Scale (ZDS), and Health Related Quality of Life (HRQL) questionnaires; and compared outcomes indices with a normative sample of neighborhood-selected control subjects in Barranquilla without GBS. RESULTS: Median age at time of acute neurologic onset was 49 years (range, 10-80); 17 (50%) were male. No deaths occurred. At long-term follow-up, 25 (73%) patients had a HDS 0-1, indicating complete / near complete recovery. Among the group, HDS (mean 1.4, range 0-4), ODSS (mean 1.9, range 0-9) and ZDS score (mean 34.4, range 20-56) indicated mild / moderate ongoing disability. Adjusting for age and sex, Zika virus-associated GBS cases were similar to a population comparison group (n = 368) in Barranquilla without GBS in terms of prevalence of physical or mental health complaints, though GBS patients were more likely to have an ODSS of ≥ 1 (OR 8.8, 95% CI 3.2-24.5) and to suffer from moderate / moderate-severe depression (OR 3.89, 95% CI 1.23-11.17) than the comparison group. CONCLUSIONS: Long-term outcomes of Zika virus-associated GBS are consistent with those associated with other antecedent antigenic stimuli in terms of mortality and ongoing long-term morbidity, as published in the literature. Persons with Zika virus-associated GBS more frequently reported disability and depression after approximately one year compared with those without GBS.

Dengue, chikungunya and zika virus coinfection: results of the national surveillance during the zika epidemic in Colombia.

Our objective was to determine the frequency of zika (ZIKV), chikungunya (CHIKV) and dengue (DENV) virus coinfection and describe the mortality cases that occurred during the epidemiologic surveillance of the ZIKV epidemic in Colombia. We analysed all cases of suspected ZIKV infection that were reported to the National Institute of Health (October 2015-December 2016). DENV, CHIKV and ZIKV RNA were detected in serum or tissue samples using polymerase chain reaction assay. Medical records of the fatal cases were reviewed. We identified that 23 871 samples were processed. The frequency of viral agents was 439 (1.84%) for DENV, 257 (1.07%) for CHIKV and 10118 (42.38%) for ZIKV. Thirty-four (0.14%) cases of coinfection were identified. The CHIKV-ZIKV coinfection was present in 28 cases (82.3%), DENV-CHIKV in three (8.8%) and DENV-ZIKV in three (8.8%). Seven (20.6%) coinfection cases were fatal (two DENV-CHIKV cases and five CHIKV-ZIKV cases). Two cases were foetal deaths and the others were related to neurological syndrome and sepsis. In conclusion, the frequency of arbovirus coinfection during epidemic of ZIKV was low, and CHIKV-ZIKV coinfection was the most common. Mortality was high among coinfection patients. The role of each virus in the mortality cases of coinfection warrants further studies.

Health-related quality of Life of an adult population sample in Barranquilla, Colombia / Calidad de vida relacionada con salud en una muestra de población adulta en Barranquilla, Colombia

ABSTRACT Objective The aim of this study was to estimate values of health-related quality of life (HRQOL) by focusing on the physical and mental health of an adult population sample in the city of Barranquilla, Colombia. Materials and Methods Cross-sectional study with 368 adults representing an adult population. The questionnaires included the health-related quality of life "CDC-Healthy Days", the Zung Self-Rating Depression Scale, and the Overall Disability Sum Score. The prevalence of fair or poor health status (FPH), frequent physical distress (FPD), frequent mental distress (FMD), and frequent activity limitation (FAL) was estimated according to socio-demographic characteristics, presence of depression, and physical disability. Results The mean age of 368 adults was 45.6 ± 18.3 years; 55.7% were males. Only 21% of this population considered their general health to be fair or poor. The prevalence of FPH, FPD, FMD and FAL was higher in women than in men, and increased with greater severity of depression and higher physical disability. Moreover, 12% of the population presented with mild depression, 3.8% with moderate depression, and less than 1% with severe depression. 94% of this population did not have an arms or legs disability. Discussion This study provides HRQOL values for an adult sample of the population of Barranquilla, Colombia. Overall, the HRQOL of this population, with subtle differences, is similar to other reports from Colombia. In general, women and people with depression and physical disabilities had a worse quality of life.(AU)

ABSTRACT Objective To describe the lifestyles and health status of returning Venezuelan and Colombian migrants in Villa Caracas, Barranquilla, in 2018. Methods Descriptive, cross-sectional study with systematic sampling of dwellings. 229 people over 15 years of age from 90 homes were included. Results Differences were found in the routes to arrive, commuting times and stay in the settlement between Venezuelan and returning Colombian migrants. Housing conditions and access to public services are limited: less than half of the dwellings have access to aqueduct, sewerage and bathrooms. In general, self-reported health status of migrants is very good or good and the prevalence of noncommunicable diseases was relatively low, with the exception of high blood pressure. Most of the people who consulted the emergency department reported effective access. Clinically significant depressive symptoms were found in 20% of the surveyed population. Conclusions The migrants of Villa Caracas are under high social vulnerability conditions given their economic and environmental conditions. Despite their lack of enrollment in the Colombian health system, they reported access to emergency care.(AU)
