Uric acid and risk of pre-eclampsia: results from a large case-control study and meta-analysis of prospective studies.

To quantify the association between maternal uric acid levels and pre-eclampsia risk in a large collection of primigravid women. A case-control study (1365 cases of pre-eclampsia and 1886 normotensive controls) was conducted. Pre-eclampsia was defined as blood pressure ≥ 140/90 mmHg and proteinuria ≥ 300 mg/24 h. Sub-outcome analysis included early, intermediate, and late pre-eclampsia. Multivariable analysis for pre-eclampsia and its sub-outcomes was conducted using binary and multinomial logistic regression, respectively. Additionally, a systematic review and meta-analysis of cohort studies measuring uric acid levels < 20 weeks of gestation was performed to rule out reverse causation. There was a positive linear association between increasing uric acid levels and presence of pre-eclampsia. Adjusted odds ratio of pre-eclampsia was 1.21 (95%CI 1.11-1.33) for every one standard deviation increase in uric acid levels. No differences in the magnitude of association were observed between early and late pre-eclampsia. Three studies with uric acid measured < 20 weeks' gestation were identified, with a pooled OR for pre-eclampsia of 1.46 (95%CI 1.22-1.75) for a top vs. bottom quartile comparison. Maternal uric acid levels are associated with risk of pre-eclampsia. Mendelian randomisation studies would be helpful to further explore the causal role of uric acid in pre-eclampsia.

Effect of Antioxidants in the Treatment of COPD Patients: Scoping Review.

Chronic obstructive pulmonary disease (COPD) is a common, preventable, treatable lung disease characterized by persistent respiratory symptoms and airflow limitation and multiorgan impact. This affects the nutritional status of patients and requires multidimensional interventions including nutritional interventions according to individual metabolic needs. Our scoping review determined the effects of antioxidants in the treatment of COPD patients and their role in the decrease in the probability of exacerbations, hospital readmissions, and changes in lung function. The sources MEDLINE, LILACS, and Google Scholar were consulted and 19 studies were selected. The most indicated antioxidants are N-Acetylcysteine, vitamins E and D, and Zinc. Other antioxidants from plants or fruits extracts are also being investigated. The beneficial effect of antioxidants in stable or exacerbated patients is not clear, but theoretical and biological arguments of benefit justify lines of research that specify the impact on reducing oxidative stress and negative effects in COPD.

Validación de la escala QLQ-C15 PAL, para evaluar calidad de vida en pacientes en cuidados paliativos, al español colombiano / Validation of the QLQ-C15 PAL Scale, to assess quality of life in patients in palliative care, to colombian spanish

Validar la escala QLQ C15 PAL, para evaluar calidad de vida en pacientes en cuidados paliativos, al español colombiano, considerando un análisis psicométrico desde la teoría clásica de los test. Método: Muestra por conveniencia de 155 pacientes oncológicos atendidos por el Programa de Cuidados Paliativos de un grupo de centros hospitalarios en las ciudades de Bogotá y Cali en Colombia. Para estimar la validez de constructo, se utilizó el análisis factorial exploratorio (AFE) con rotación varimax; posteriormente, se usaron cargas factoriales para estimar el coeficiente Omega y posteriormente el análisis de Rash reconocido Análisis de la Teoría de la respuesta al ítem (TRI). El análisis fue realizado en Winsteps 2.80. Resultados: Todas las correlaciones son significativas entre los ítems de la escala Funcionamiento Global (FG) con el puntaje total obtenido en esta escala y el puntaje total del QLQ PAL-15; la misma situación ocurre con los ítems de la escala Funcionamiento Emocional (FE) que correlaciona de modo directamente proporcional y con una magnitud alta con el puntaje total del QLQ PAL-15. En cuanto al total de la escala, existe un adecuado ajuste para los ítems ya que sus valores Infit: (IMNSQ 0,99; ZSDT: -0,3) y Outfit (OMNSQ 1,02; ZSDT-0,2) se encuentran dentro de los rangos establecidos como parámetros de ajuste. Conclusiones: La validación del EORTC QLQ-C15-PAL demostró propiedades psicométricas satisfactorias al aplicarse en pacientes con enfermedad oncológica avanzada en Colombia. Se plantea para estudios posteriores realizar ajuste en la redacción de los ítems 7,11 y 13 para que estos discriminen de manera precisa el rasgo que pretenden medir (AU)

Validate the QLQ C15 PAL scale, to assess the quality of life in patients in palliative care, to Colombian Spanish, based in a classical psychometric analysis. Methodology: Convenience sample of 155 cancer patients attended by the Palliative Care Program of a group of hospitals in the cities of Bogota and Cali in Colombia. To estimate construct validity, exploratory factor analysis (AFE) with varimax rotation was used; Factorial loads were subsequently used to estimate the Omega coefficient and subsequently Rash’s recognized Analysis of Item Response Theory (TRI). The analysis was performed on Win steps 2.80. Results: All correlations are significant between the items on the Global Operation (FG) scale with the total score obtained on this scale and the total score of the QLQ PAL-15; the same situation occurs with items on the Emotional Functioning (FE) scale that correlates directly proportionally and with a high magnitude with the total score of QLQ PAL-15.As for the total scale, there is an appropriate adjustment for the items since their Infit values: (IMNSQ 0.99, ZSDT: -0.3) and Outfit (OMNSQ 1.02, ZSDT-0.2) are within the ranges set as adjustment parameters. Conclusion:The validation of the EORTC QLQ-C15-PAL demonstrated satisfactory psychometric properties in patients with advanced cancer disease in Colombia. It is proposed for subsequent studies to adjust the wording of items 7,11 and 13 so that they discriminate in a precise way the feature that they intend to measure (AU)

Seroprevalence of SARS-CoV-2 Infection among Occupational Groups from the Bucaramanga Metropolitan Area, Colombia.

The negative effects of coronavirus disease 2019 (COVID-19) pandemic have impacted the world economy due to the absence from work because of SARS-CoV-2 infection in workers, among other reasons. However, some economic areas are essential to society and people must continue working outside the home to support economic reactivation; their serological profile could be different from that of the global population. Cross-sectional study: Workers from health, construction, public transportation, public force, bike delivery messengers, independent or informal commerce areas, and residents of Bucaramanga or its metropolitan area were invited to participate. All participants self-completed a virtual survey and a blood test was taken to assess IgG and IgM with the ARC COV2 test. Seroprevalence was estimated considering a complex survey design, correcting for a finite population effect and adjusting for test performance. A total of 7045 workers were enrolled; 59.9% were women and most were residents of Bucaramanga and working in health occupations. The global adjusted seroprevalence was 19.5% (CI: 95% 18.6-20.4), being higher for Girón (27.9%; 95% CI: 24.5-31.30). Workers with multiple contact with people during working hours or using public transportation to go to work had a higher frequency of seropositivity for SARS-CoV-2. The seroprevalence among workers living in these four municipalities from the Colombian northeast area is still low.

Características clínico-epidemiológicas de los pacientes con pitiriasis versicolor en un centro de referencia de Colombia / Clinical-epidemiological characteristics of patients with tinea versicolor in a Colombian reference center

Resumen Objetivo: describir las características socio-demográficas, presentación clínica y condiciones extrínsecas que pueden favorecer el desarrollo de la pitiriasis versicolor. Material y métodos: estudio observacional descriptivo, de corte transversal y prospectivo, en el que se incluyeron pacientes con diagnóstico clínico y micológico de pitiriasis versicolor entre enero y diciembre de 2018, que asistieron al Hospital Universitario Centro Dermatológico Federico Lleras Acosta. Resultados: se incluyeron un total de 42 pacientes con diagnóstico de pitiriasis versicolor confirmado por examen directo, el 62% fueron hombres con una edad promedio de 33 años. La localización más común fue el tórax anterior (68%) y posterior (65%), en fototipos III y IV (78.5%), con una tonalidad hipocrómica. El 28% presentaron cuadros recurrentes, con síntomas hasta 7 años antes de la consulta. El signo de Besnier fue positivo en el 95% de los casos. El 64% refirió antecedente personal de hiperhidrosis y el 67% practicaba algún deporte como buceo, natación o gimnasia. Discusión: la identificación de las condiciones extrínsecas presentes esta población permite orientar medidas de prevención para evitar recurrencias de pitiriasis versicolor. Los viajes a lugares de clima cálido y la práctica de deportes son factores que favorecen el desarrollo de la micosis. En las formas clínicas atípicas se sugiere realizar siempre el examen micológico directo para confirmar el diagnóstico. El signo de Besnier es una maniobra útil para el diagnóstico clínico de la pitiriasis versicolor, particularmente cuando el acceso al examen directo es limitado.

Abstract Objective: to describe the sociodemographic aspects, clinical presentation and extrinsic conditions that may increase the risk of developing pityriasis versicolor. Materials and methods: a descriptive, cross-sectional and prospective observational study was conducted. Patients with clinical and mycological diagnosis of ptyriasis versicolor were included from january to december 2018 who attended to the Hospital Universitario Centro Dermatológico Federico Lleras Acosta. Results: a total of 42 patients were included in the study, all of them had confirmed mycological diagnosis of pityriasis versicolor. The most common location of the lesions was the anterior thorax (68%) and posterior thorax (65%), in III and IV phototypes (78.5%) with a hypochromic color. 28% had recurrent infection, with symptoms mean of 7 years before the consultation. The Besnier sign was positive in 95% of cases, 64% reported personal history of hyperhidrosis and 67% practiced some sports: diving, swimming and gymnastics. Discussion: recognizing extrinsic conditions that may increase the risk of developing pitiraisis versicolor in this population allows identifying control measures to prevent a relapse. The main factors involved in the development of pitiraisis versicolor were traveling to places with high temperatures and sport practice. In atypical clinical presentation it is mandatory to perform the mycological direct test to confirm the diagnosis. The Besnier sign is a useful method for the clinical diagnosis of pityriasis versicolor, particularly when access to direct examination is limited.

Introduction: Actinic prurigo is a chronic photodermatosis. It affects the Latin American population more frequently, predominantly women, and involves the sun-exposed areas of the skin, conjunctiva, and lips. Objective: To update the information on the clinical-epidemiological characteristics and treatment of patients with actinic prurigo in Colombia. Materials and methods: We conducted a cross-sectional study including the medical records of patients with actinic prurigo treated in the Photodermatology Service of Hospital Universitario Centro Dermatológico Federico Lleras Acosta between 2011 and 2016. We described the demographic, clinical, histopathological, and treatment characteristics of the patients. Results: We included 108 patients, 77 (71.3%) were women and 31 (28.7%) men, mainly with phototypes III-IV (70%). The disease had begun during the first decade of life in 66.4% of the cases and 25% of the patients had a family history with the condition. The lesions predominated on the face (93.5%), forearms (79.6%), and back of the hands (70.4%). Ocular (87.9%) and lip (88.8%) involvement was also documented. A photo-provocation test with UVA was performed in 25% of the cases and skin biopsies in 19.4%. Physical and chemical photoprotection was indicated in all patients. Mild to moderate cases were treated with topical corticosteroids (91.7%) and calcineurin inhibitors (65.7%) while severe cases received thalidomide (33.3%) and pentoxifylline (14.8%). Conclusion: The characteristics of actinic prurigo patients in Colombia are similar to those reported in other Latin American countries: early onset of the disease, predominance in women, frequent involvement of conjunctiva and lips, and adequate response to topical and systemic treatment.

C-reactive protein, interleukin-6 and pre-eclampsia: large-scale evidence from the GenPE case-control study.

Multiple small studies have suggested that women with pre-eclampsia present elevated levels of C-reactive protein (CRP) and interleukin-6 (IL-6). However, little is known regarding the source of this CRP and IL-6 increase. Therefore, the aim of this study was to evaluate the relationship between CRP and IL-6 levels with pre-eclampsia considering different confounding factors. Using data from a large Colombian case-control study (3,590 cases of pre-eclampsia and 4,564 normotensive controls), CRP and IL-6 levels were measured in 914 cases and 1297 controls. The association between maternal serum levels of CRP and IL-6 with pre-eclampsia risk was evaluated using adjusted logistic regression models. Pre-eclampsia was defined as presence of blood pressure ≥140/90 mmHg and proteinuria ≥300mg/24 h (or ≥1 + dipstick). There was no evidence of association between high levels of CRP and IL-6 with pre-eclampsia after adjusting for the following factors: maternal and gestational age, ethnicity, place and year of recruitment, multiple-pregnancy, socio-economic position, smoking, and presence of infections during pregnancy. The adjusted OR for 1SD increase in log-CRP and log-IL-6 was 0.96 (95%CI 0.85, 1.08) and 1.09 (95%CI 0.97, 1.22), respectively. Although previous reports have suggested an association between high CRP and IL-6 levels with pre-eclampsia, sample size may lack the sufficient power to draw robust conclusions, and this association is likely to be explained by unaccounted biases. Our results, the largest case-control study reported up to date, demonstrate that there is not a causal association between elevated levels of CRP and IL-6 and the presence of pre-eclampsia.

Pentraxin-3 is a candidate biomarker on the spectrum of severity from pre-eclampsia to HELLP syndrome: GenPE study.

Pentraxin-3 has been reported as a promising biomarker of pre-eclampsia and its severity; however, available studies have small sample sizes, and analyses are not always adjusted for confounders. The aim of this study is to establish the strength of the association between maternal Pentraxin-3 level and pre-eclampsia or HELLP syndrome. It was a case-control study. Women with pre-eclampsia or HELLP syndrome were defined as cases, and women with healthy pregnancies at term (>37 weeks) were classified as controls. Plasma concentrations of Pentraxin-3 were determined at the time of delivery by quantitative enzyme immunoassay. Associations between Pentraxin-3 and pre-eclampsia and HELLP syndrome were assessed by multinomial logistic regression. Subsidiary analysis for the time of disease onset was also carried out. Odds ratios and 95% confidence intervals are reported. A total of 1024 pregnant women were included (461 controls, 368 pre-eclampsia, 195 HELLP). A positive log-linear relationship was found between the top pentraxin-3 quintile and HELLP syndrome. After adjustment for confounders (maternal age, ethnicity, socioeconomic position, date and place of recruitment, family history of pre-eclampsia, smoking, body mass index at beginning of pregnancy, gestational age and multiple pregnancy), the strength of the association was higher for HELLP syndrome [OR 1.13 (95% CI 1.08; 1.18)] than for pre-eclampsia [OR 1.03 (95% CI 1.03; 1.10)]. No difference according to time of onset or pentraxin-3 level was found. In summary, pentraxin-3 level was associated with pre-eclampsia, but it was more strongly associated with HELLP syndrome. Longitudinal studies with a lower probability of residual confounding are necessary to improve our knowledge about the role of pentraxin-3 in pre-eclampsia.

Experiencia de un programa de soporte oncológico y cuidados paliativos en Colombia / The Palidem study: care at the end of life in institutionalized patients with advanced dementia

OBJETIVO: Desarrollar un plan de atención específi co en pacientes con demencia avanzada institucionalizados, planificando los cuidados mediante el control sintomático, tomando decisiones con el cuidador principal, realizando un apoyo psicológico y espiritual. MÉTODO: Estudio descriptivo de periodo en el Centro Txara 1, desde el 1 de julio de 2014 hasta el 31 de diciembre de 2016, identifi cando a aquellos residentes con demencia avanzada y síndrome de declive. Se recoge trimestralmente el grado de control de síntomas (Symptom Management at the End-of-Life in Dementia) (SM-EOLD), utilizando la escala PAINAD para la valoración del dolor; el confort en el momento de la agonía se determina diariamente (The Comfort Assessment in Dying with Dementia) (CAD-EOLD), estableciendo con el cuidador principal la toma de decisiones basadas en los objetivos asistenciales paliativos. Tras el fallecimiento se realiza una encuesta de satisfacción al cuidador (Satisfaction with Care at the End-of-Life in Dementia) (SWC-EOLD) y contacto periódico con la pastoral para el apoyo espiritual. RESULTADOS: Se han analizado 74 residentes, con una edad media de 87 años, un 79 % mujeres, con 4,6 medicamentos de media, con enfermedad de Alzheimer como principal causa de demencia. En el control de síntomas en fase estable no se detecta inestabilidad física o conductual relevante, detectándose en un 5 % la presencia de dolor. De 50 residentes fallecidos, el 94 % sucede en el propio centro, en un 67 % se puede registrar el grado de confort destacando la presencia de disnea y disfagia, al ser la infección respiratoria aspirativa la principal causa de fallecimiento. En un 66 % de la población seleccionada se realiza atención espiritual. Un 30 % de los cuidadores principales responden a la encuesta de satisfacción, con un alto porcentaje de aceptación en el nivel de cuidados. CONCLUSIONES: La identificación de los pacientes con demencia avanzada en situación de final de vida permite estructurar un plan de atención en el centro gerontológico, conociendo las necesidades sintomáticas, el grado de confort o bienestar y consensuando las decisiones en cuanto a la proporcionalidad de cuidados con la familia. Ante situaciones de descompensación aguda, la coordinación con los recursos sociosanitarios disponibles es fundamental para poder llevar a cabo las decisiones adoptadas del equipo sanitario con el cuidador principal

OBJECTIVE: To develop a specific care plan for institutionalized patients with advanced dementia based on symptom control and including joint decision making with the primary caregiver as well as psychological and spiritual support. METHOD: A descriptive 1-period study at Centro Txara 1, from July 1 2014 to December 31 2016, which identified residents with advanced dementia and geriatric failure-to-thrive syndrome. Symtom control extent was quarterly assessed using the Symptom Management at the End-of-Life in Dementia (SM-EOLD) scale, and the PAINAD scale for pain; comfort at the end of life was assessed daily with the Comfort Assessment in Dying with Dementia (CAD-EOLD) instrument, and decisions were made jointly with the primary caregiver based on the goals of palliative care. After the death of the patient a satisfaction survey was administered to the caregiver (Satisfaction with Care at the End-of-Life in Dementia, SWC-EOLD), who was also provided with regular contact with the pastoral care team for spiritual support. RESULTS: A total of 74 residents were assessed with a mean age of 87 years; 79% were females, mean number of drugs was 4.6, and Alzheimer's disease was the primary cause of dementia. Stable-phase symptom control identified no relevant phisical or behavioral instability, but pain was found in 5% of the sample. Of 50 residents who passed away, 94% died in the hospice; in 67% comfort degree could be collected, and the presence of shortness of breath and dysphagia stood out, as aspiration-induced respiratory infection was the primary cause of death. Spiritual care was provided for 66% of the study population. In all, 30% of primary caregivers responded to the satisfaction survey showing a high percentage of acceptance of level of care. CONCLUSIONS: Identifying patients with advanced dementia at the end of life allows the development of a hospice care plan considering symptom needs, comfort degree and wellbeing, and involving consensus decisions about care proportionality with the family. Should an acute decompensation occur, coordination with the available social and healthcare resources is key for implementing the decisions agreed between the healthcare team and the primary caregiver

The cost of hospital care for HIV patients in Colombia: an insurer's perspective.

The aim of this study was to evaluate the cost derived from the hospitalization of people living with HIV (PLHIV) in Colombia between 2011 and 2015. This is an analysis of the direct cost of PLHIV hospitalization from the perspective of an insurer of the Colombian General Social Security System. The costs were calculated in Colombian pesos and corrected for inflation on the basis of the 2017 Consumer Price Index of the Bank of the Republic of Colombia. It was converted to US dollars at the Market Representative Exchange Rate of the same year. We analyzed 1129 hospitalizations in 612 PLHIV, of which 12% started with a diagnosis of HIV during the same hospitalization, with the majority in the AIDS stage (63%). The median overall cost of hospitalizations was US$1509 (25th and 75th percentiles: US$711-US$3254), being even higher in patients with AIDS and as the CD4 T lymphocyte count decreased. The cost derived from the medical care of PLHIV increases as the clinical control of the disease worsens, and it is a key indicator of the impact of the strategies implemented for the timely identification of the infection and subsequent management of the disease.

Ácido úrico y su asociación con los componentes del síndrome metabólico en adolescentes colombianos / Uric acid and its association with the components of the metabolic syndrome in Colombian adolescents

Introducción: la relación del ácido úrico y el desarrollo de enfermedades cardiometabólicas se ha estudiado en los últimos años. No obstante, continúa la controversia en considerar este hallazgo como un factor de riesgo independiente para enfermedad cardiovascular en edades tempranas. El objetivo fue establecer la prevalencia de niveles séricos de ácido úrico alterados y su asociación con los componentes del síndrome metabólico en adolescentes de Bucaramanga, Colombia. Metodología: estudio de corte transversal analítico, anidado en una cohorte poblacional, con una muestra de 494 adolescentes recontactados del estudio original. Las variables dependientes fueron: síndrome metabólico y criterios que lo componen. La variable independiente principal fueron los valores de ácido úrico, clasificados en dos categorías: ácido úrico a riesgo (valores mayores a 5,5 mg/dl) y ácido úrico elevado (mayores de 6,5 mg/dl). Se usaron modelos de regresión logística, ajustados por sexo, edad e índice de masa corporal para determinar la asociación entre las variables de interés. Resultados: la prevalencia de ácido úrico a riesgo fue del 37,25% (IC 95%, 32,9-41,5) y la proporción de ácido úrico elevado fue del 18,42% (IC 95%, 14,9-21,8), significativamente mayor en hombres que en mujeres (p < 0,0001). Los adolescentes con niveles elevados de ácido úrico mostraron mayor probabilidad de presentar obesidad abdominal (OR: 3,03; IC 95% 1,38-6,64), presión arterial alta (OR: 1,11; IC 95% 1,05-2,07), hipertrigliceridemia (OR: 4,94; IC 95%, 2,98-8,19) y glucemia en ayuno alterada (OR: 5,15; IC 95%, 3,42-11,05). Conclusiones: los resultados sugieren la existencia de una relación positiva entre la presencia de niveles de ácido úrico elevados y los factores de riesgo cardiometabólico

Background: the relationship of uric acid and the development of cardiometabolic diseases has been studied in recent years. However, the controversy continues to consider this finding as an independent risk factor for cardiovascular disease at early ages. The objective was to establish the prevalence of serum levels of altered uric acid and its association with the metabolic syndrome components in adolescents from Bucaramanga, Colombia. Methods: an analytical cross-sectional study, nested in a population cohort, with a sample of 494 re-contacted adolescents from the original study. The dependent variables were metabolic syndrome and its component criteria. The main independent variable was uric acid values, classified into two categories: uric acid at risk (values greater than 5.5 mg/dl) and high uric acid (greater than 6.5 mg/dl). Logistic regression models were used, adjusted for sex, age and body mass index to determine the association between the variables of interest. Results: the prevalence of uric acid at risk was 37.25% (CI 95%, 32.9-41.5) and the proportion of high uric acid was 18.42% (CI 95%, 14.9-21, 8), significantly higher in men than in women (p < 0.0001). Adolescents with high levels of uric acid were more likely to have abdominal obesity (OR: 3.03, CI 95% 1.38-6.64), high blood pressure (OR: 1.11, CI 95%, 1.05-2.07), hypertriglyceridemia (OR: 4.94, CI 95%, 2.98-8.19) and altered fasting glycemia (OR: 5.15, CI 95%, 3.42-11.05). Conclusions: the results suggest the existence of a positive relationship between the presence of high levels of uric acid and metabolic cardio-risk factors

Conclusions: the results suggest the existence of a positive relationship between the presence of high levels of uric acid and metabolic cardio-risk factors.

INTRODUCCIÓN: Introducción: la relación del ácido úrico y el desarrollo de enfermedades cardiometabólicas se ha estudiado en los últimos años. No obstante, continúa la controversia en considerar este hallazgo como un factor de riesgo independiente para enfermedad cardiovascular en edades tempranas. El objetivo fue establecer la prevalencia de niveles séricos de ácido úrico alterados y su asociación con los componentes del síndrome metabólico en adolescentes de Bucaramanga, Colombia. Metodología: estudio de corte transversal analítico, anidado en una cohorte poblacional, con una muestra de 494 adolescentes recontactados del estudio original. Las variables dependientes fueron: síndrome metabólico y criterios que lo componen. La variable independiente principal fueron los valores de ácido úrico, clasificados en dos categorías: ácido úrico a riesgo (valores mayores a 5,5 mg/dl) y ácido úrico elevado (mayores de 6,5 mg/dl). Se usaron modelos de regresión logística, ajustados por sexo, edad e índice de masa corporal para determinar la asociación entre las variables de interés. Resultados: la prevalencia de ácido úrico a riesgo fue del 37,25% (IC 95%, 32,9-41,5) y la proporción de ácido úrico elevado fue del 18,42% (IC 95%, 14,9-21,8), significativamente mayor en hombres que en mujeres (p < 0,0001). Los adolescentes con niveles elevados de ácido úrico mostraron mayor probabilidad de presentar obesidad abdominal (OR: 3,03; IC 95% 1,38-6,64), presión arterial alta (OR: 1,11; IC 95% 1,05-2,07), hipertrigliceridemia (OR: 4,94; IC 95%, 2,98-8,19) y glucemia en ayuno alterada (OR: 5,15; IC 95%, 3,42-11,05). Conclusiones: los resultados sugieren la existencia de una relación positiva entre la presencia de niveles de ácido úrico elevados y los factores de riesgo cardiometabólico.

Dolor en pacientes hospitalizados en una institución de salud de tercer nivel / Pain in hospitalized patients in a third-level health care institution

Abstract Introduction: Pain is one of the major symptoms experienced by hospitalized patients. Objective: To establish the hospital care quality indicators associated with pain management (prevalence, intensity, and interference) in adult inpatients, following the implementation of strategies framed within the pain-free Hospital Policy at a third-level institution. Methodology: Observational, descriptive, cross-sectional trial. Patients over 18 years of age, hospitalized for more than 24hours, and who previously signed their informed consent were included. The Brief Pain Inventory - Short Form in Spanish was adminis tered for pain evaluation, and the sex and service differences were estimated using the Wilcoxon test for quantitative variables and x2 for qualitative variables. Results: Three hundred thirty-eight participants were includ ed. The prevalence of pain was 43.4%, with a higher percentage among females (52.1% vs 28.8%, P <0.001) and in the surgical services (48.0% vs 37.5%, P = 0.05). Women showed higher intensity in the "minimum pain" item (median 3 interquartile range 2-5 vs median 2 interquartile range 0-1, P=0.009). The activities with the highest interference were sleep and general activity in both sexes and services. Discussion: The hospital quality of care indicators herein measured allow for an enhanced approach to characterize pain in this population group, with a view to improving pain identifica tion and management in the future to provide a more comfortable experience for the patient.

Hemoglobinopathy detection through an institutional neonatal screening program in Colombia / Detecção de hemoglobinopatias por meio de um programa institucional de triagem neonatal na Colômbia

ABSTRACT Introduction: Hemoglobinopathies are among the most common genetic disorders of hemoglobin worldwide and a public health problem. In Colombia, even though geographical areas with high incidence of this disorder have been reported, the absence of a national screening program does not permit us to determine its prevalence. Objective: Establish the prevalence of hemoglobin variants in a population covered by the neonatal screening program of Clínica Colsanitas S.A., between June 2000 and December 2014, including eight capital cities in Colombia. Methods: A retrospective cross-sectional study was conducted. We collected data from reports of the neonatal hemoglobinopathy-screening program for full-term newborn babies between 5 and 15 days old. Qualitative hemoglobin analysis was performed using gel electrophoresis of blood samples taken from the babies' heels. Results: The overall prevalence of abnormal Hb was 1.3%. Within the groups of newborns affected with any hemoglobinopathy (n = 400), the most frequent abnormal structural hemoglobins found were HbS (43%), HbC (9%), fast Hb (8%). For quantitative hemoglobins, HbA2 was 3.7% and HbA kept slightly elevated in 14.7% of cases. Frequency of homozygosis for HbS was 0.01%. Barranquilla, Cartagena and Cali were the cities with the greatest frequency of hemoglobinopathies. No correlation between sex and abnormal hemoglobin was found. Discussion and conclusion: Taking in consideration data from the World Health Organization (WHO) on hemoglobinopathies, our prevalence of > 1% is considered high. Therefore, a more extended coverage and the need for a national screening program are priorities.

RESUMO Introdução: As hemoglobinopatias são doenças genéticas comuns em todo o mundo e representam um problema de saúde pública. Na Colômbia, embora existam áreas geográficas com maior risco de apresentá-las, não há programas de triagem nem estudos para estabelecer sua prevalência na população. Objetivo: Estabelecer a prevalência de variantes de hemoglobina (Hb) na população pertencente ao programa de triagem neonatal da Clínica Colsanitas S.A. entre junho de 2000 e dezembro de 2014, em oito cidades do país. Métodos: Estudo transversal retrospectivo. Os registros do programa de triagem neonatal das hemoglobinopatias foram revistos para a informação dos resultados de eletroforese de hemoglobina em pH alcalino, praticada no sangue dos recém-nascidos com idades compreendidas entre 5-15 dias. Resultados: A prevalência geral de Hb anormal foi de 1,3%. Dentro dos grupos de recém-nascidos afetados com qualquer hemoglobinopatia (n = 400), as hemoglobinas anormais estruturais mais frequentes foram hemoglobina S (HbS) (43%), hemoglobina C (HbC) (9%) e Hb rápida (8%). Para as Hb quantitativas, o aumento da hemoglobina A2 (HbA2) foi de 3,7%, e a hemoglobina A (HbA) aumentada permaneceu ligeiramente elevada em 14,7% casos. A frequência de homozigotos para HbS foi de 0,01%. Barranquilla, Cartagena e Cali foram as cidades com maior frequência de hemoglobinopatias. Não houve associação entre sexo e presença de algum tipo de Hb. Discussão e conclusão: A prevalência global de hemoglobinopatias em nosso estudo foi alta (> 1%) de acordo com os critérios da Organização Mundial de Saúde (OMS). Portanto, há a necessidade de implementação de programas de triagem neonatal com maior cobertura nacional para as hemoglobinopatias.

Preeclampsia y riesgo cardiovascular: estudio de seguimiento en la población de GenPE en Colombia / Pre-eclampsia and cardiovascular risk: a follow-up study of the GenPE population in Colombia

Introducción: las mujeres con antecedente de preeclampsia (PE) tienen mayor riesgo de desarrollar enfermedad cardiovascular. El estudio GenPE ha captado gestantes con y sin PE en Colombia durante diez años, haciendo posible hoy evaluar desenlaces cardiovasculares en este grupo. Objetivo: determinar la presencia de enfermedad cardiovascular en mujeres jóvenes expuestas o no a preeclampsia, captadas por el estudio GenPE en Bucaramanga, Colombia. Materiales y métodos: estudio de cohorte que incluyó 106 pacientes –a partir de la cohorte original, 666 pacientes (2005-2010)–, menores de 26 años, primigestantes, sin antecedentes de enfermedades crónicas. Se realizó examen físico y venopunción para glucemia, perfil lipídico, ácido úrico y apolipoproteínas A-I y B. Se evaluó la presencia de hipertensión arterial (HA), obesidad, diabetes mellitus tipo 2 y síndrome metabólico. Se establecieron diferencias entre las mujeres expuestas y no expuestas a preeclampsia y el cambio entre el ingreso a GenPE y el primer seguimiento mediante test Wilcoxon o chi cuadrado y riesgo relativo con IC 95%. Resultados: se encontró asociación entre la exposición a PE con cifras mayores de presión arterial diastólica (p = 0,003) e hipercolesterolemia (p = 0,040). En toda la población existen niveles subóptimos de colesterol HDL y Apo A-I. Al primer seguimiento no se evidencia asociación con desenlaces fuertes, tales como: hipertensión arterial, obesidad, diabetes mellitus tipo 2, síndrome metabólico. Conclusión: en una muestra de mujeres colombianas jóvenes expuestas y no expuestas a PE, en un primer seguimiento, en los primeros dos años posteriores al parto, se evidencian cambios en la presión arterial diastólica (PAD), y biomarcadores asociados a riesgo cardiovascular.

Introduction: Females having a background of pre-eclampsia (PE) are at greater risk of developing cardiovascular disease. The GenPE study has captured pregnant females with and without PE in Colombia during the last 10 years, making it possible today to evaluate cardiovascular outcomes in this group. Objective: Determining the presence of cardiovascular disease in young females who were and were not exposed to preclampsia and who were recruited by the GenPE study carried out in Bucaramanga, Colombia. Materials and methods: This was a cohort study which included 106 primiparous patients aged less than 26 years old having no background of chronic disease taken from an original cohort of 666 patients (2005-2010). They were physically examined and venopuncture was made for glycemia, lipid profile, uric acid and apolypoprotein A-I and B. The presence of hypertension, obesity, type 2 diabetes mellitus and metabolic syndrome were evaluated. Differences were established by Wilcoxon or Chisquared tests (relative risk and 95% CI) between females who had been exposed to PE and those who had not been so and the change between entering the GenPE study and the first follow-up. Results: An association was found between exposure to PE and having higher diastolic pressure figures (p = 0.003) and hypercholesterolemia (p = 0.040). Sub-optimal HDL cholesterol and apo A-I levels were found in the whole population. No association with strong outcomes was found during the first follow-up, such as hypertension, obesity, type 2 diabetes mellitus or metabolic syndrome. Conclusion: Changes in peripheral arterial disease (PAD) and cardiovascular risk-associated biomarkers became evident in a sample of young colombian females who developed PE during the first followup within 2 years after delivery.

El papel de lasffracciones lipídicas, lipoproteínas y apolipoproteínas en preeclampiaa / The role f lipidd fractions, lipoproteins and apolipoproteins in preeclampsia / O papel das raçõões lipídicas, lipoproteínas e apolipoproteínas na preeclampsia

La Preeclampsia (PE) es un trastorno multisistémico, exclusivo de la gestación humana y responsable de aproximadamente 44.000 muertes maternas anuales a nivel mundial; esta enfermedad está asociada a múltiples complicaciones tanto en la madre como en el feto, sin embargo, su etiología no se encuentra totalmente dilucidada y en consecuencia ha sido difícil definir estrategias válidas de predicción. La PE es una enfermedad compleja y comparte diferentes factores de riesgo con las enfermedades cardiovasculares; como la obesidad, hipertensión arterial, resistencia a la insulina y dislipidemias. Con esto se evidencia que algunas alteraciones en los niveles lípidos y apolipoproteínas, se asocian con mayor peroxidación lipídica y estrés oxidativo lo cual puede desencadenar en disfunción endotelial para ambas patologías. Por tanto, la exploración de la evidencia de una asociación entre las fracciones lipídicas y riesgo de PE, puede aportar nuevo conocimiento en torno a la etiología de esta enfermedad. En la presente revisión, se plantearán las principales implicaciones biológicas de las alteraciones del perfil lipídico y apolipoproteínas en la génesis de la PE. Se describirán los estudios observacionales que se han aproximado a su evaluación y se identificarán sus principales debilidades metodológicas, con el fin de plantear estrategias para una evaluación integral de esta vía fisiopatológica, con posibles implicaciones predictivas de la enfermedad.

Preeclampsia (PE) is a multisystemic disorder unique to human pregnancy and responsible for about 44,000 maternal deaths worldwide. This disease is associated with multiple complications for both mother and fetus; however, its etiology is not totally clear and it has therefore been difficult to define valid prediction strategies. PE is a complex disease and it shares different risk factors with cardiovascular disease, such as obesity, hypertension, insulin resistance and dyslipidemia, evidencing that the presence of disturbances in lipid and apolipoprotein levels are associated with increased lipid peroxidation and oxidative stress which can lead to endothelial dysfunction in both diseases. Therefore, exploring the evidence of an association between lipid fractions and PE risk can provide new knowledge about the etiology of this disease. In this review, the major biological implications of lipid profile and apolipoproteins alterations in the genesis of PE will be presented, describing the observational studies and identifying its main methodological weaknesses in order to create strategies for comprehensive assessment of the pathophysiological pathway with potential predictive implications of the disease.

A PE é uma doença complexa e compartilha diferentes fatores de risco com as doenças cardiovasculares, como a obesidade, hipertensão arterial, resistência à insulina e dislipidemias; evidenciando que alterações nos níveis dos lipídios e apolipoproteínas, se associam com maior peroxidação lipídica e estresse oxidativo que pode desencadear disfunção endotelial para ambas patologias. Portanto, a exploração da evidência de uma associação entre las frações lipídicas e risco de PE, pode contribuir com novo conhecimento ao redor da etiologia desta doença. Na presente revisão, serão apresentadas as principais implicações biológicas das alterações do perfil lipídico e apolipoproteínas na gênese da PE, descrevendo os estudos observacionais que se aproximaram à sua avaliação e identificando suas principais fraquezas metodológicas, com o objetivo de propor estratégias para uma avaliação integral desta via fisiopatológica, com possíveis implicações preditivas da doença.

Biomarcadores asociados a riesgo de síndrome metabólico: estudio en personal médico y administrativo de la facultad de ciencias de la salud UNAB - GENESIS II / Associated biomarkers with metabolic síndrome risk: a study among medical and administrarive staff of the UNAB health science faculty – GENESIS II

Introducción: El síndrome metabólico (SM) es factor de riesgo para mortalidad por enfermedad coronaria y diabetes mellitus. Se han propuesto nuevos marcadores de riesgo cardiovascular (RCV), con mejor capacidad pronóstica en la toma de medidas preventivas para disminuir la aparición o severidad de sus consecuencias. Objetivos: Establecer la prevalencia de SM y determinar el comportamiento de los factores de riesgo cardiovascular tradicionales y no convencionales entre hombres y mujeres de Bucaramanga, Colombia. Metodología: GÉNESIS es un estudio de cohorte prospectivo con evaluación en 2005 y 2010. Para la segunda fase, todos los participantes contestaron una encuesta semiestructurada, recibieron evaluación clínica, de presión arterial (PA) y parámetros antropométricos, así como toma de sangre periférica en ayunas para medición de coleste-rol, HDL, triglicéridos, glicemia, PCR, IL- 6, Apo A-I y Apo B. Resultados: Para la segunda fase se evaluaron 66 empleados. Se encontró una prevalencia de SM del 18.2%. La población masculina presentó los mayores valores de PA, glucemia, triglicéridos, Apo B y relación Apo B/Apo A-I, comparado con las mujeres. En el estudio de seguimiento se evaluaron 44 personas en dos momentos (2005 y 2010), donde la población femenina evidenció un aumento significativo del PA, niveles de colesterol, HDL y glucemia, así como descenso en los de PCR comparado con los hombres. Conclusión: El reconocimiento de los factores de riesgo tradicionales y no convencionales, y las diferencias de los mismos entre los géneros ayudaría a optimizar la estratificación del RCV y a futuro una mayor prevención de las enfermedades cardiovasculares.

Background: The metabolic syndrome (MS) is a risk factor for coronary heart disease and diabetes mellitus mortality. New cardiovascular risk markers have been proposed with better prognostic ability for taking preventive measures to decrease the occurrence or severity of their consequences. Objectives: To establish the prevalence of MS and to determine the behavior of traditional and no traditional cardiovascular risk factors of men and women from Bucaramanga, Colombia. Methodology: GENESIS is a prospective cohort study in 2005 and 2010 assessment. For the second phase, all participants completed a semistructured questionnaire, received clinical evaluation for blood pressure and anthropometric parameters and peripheral blood sampling for measurement of fasting glucose, cholesterol, HDL, triglycerides, CRP, IL-6, Apo AI and Apo B. Results: 66 employees were evaluated for second phase. The prevalence of MS was 18.2%. Among them, the male population had the highest values of waist circumference, glucose, triglycerides, Apo B and Apo B/Apo AI, compared with women. In Follow-up study, 44 people were assessed on two occasions (2005 and 2010); female population showed a significant increase in waist circumference, cholesterol, HDL and blood glucose levels, and decrease in CRP compared with men. Conclusion: The recognition of traditional and non-conventional risk factors, and the differences between genders would help to optimize cardiovascular risk stratification and therefore better prevention of CVD in the future.

[The prognosis for children of mothers with preeclampsia. Part 2: long-term effects]. / El pronóstico de los hijos de madres con preeclampsia. Parte 2: efectos a largo plazo.

Preeclampsia affects between 4% to 8% of all human pregnancies. It compromised both mothers and offspring beyond perinatal period. This is the second of two papers devoted to show the available evidence about the effect of preeclampsia on offsprings beyond perinatal period from cohort studies, some over 60-years follow-up. From this perspective, these children are at great risk to develop cardiovascular disorders as hypertension, as well as other disorders, as cancer or neuropsychiatric ones.
