Análisis del uso de servicios sanitarios por la población colombiana de acuerdo con niveles de atención que incluyen consulta externa y hospitalización/urgencia en relación con variables del entorno sociodemográfico a partir de los datos de la Encuesta Nacional de Salud 2007

La utilización de servicios sanitarios es la descripción del uso de servicios de salud por personas y permite identificar, planificar e intervenir en los Sistemas de Salud. El objetivo de este trabajo es analizar el uso de servicios sanitarios por la población colombiana de acuerdo con niveles de atención que incluyen consulta externa y hospitalización/urgencia en relación con variables del entorno sociodemográfico a partir de los datos de la Encuesta Nacional de Salud 2007. Se tomaron los datos de la ENS2007 se realizó un análisis descriptivo de las variables sociodemográficas y datos propios de la atención. Los datos de la ENS 2007 mostraron una mayor utilización por el sexo femenino y en los extremos de edad, la mayoría de usuarios en la región central/Bogotá DC, 15% de usuarios sin educación y un bajo porcentaje de empleo formal. Las causas más frecuentes de atención de urgencias y hospitalización fueron enfermedad aguda, crónica y lesiones por externalidades. Los datos reflejan inequidades regionales, poco empleo formal y bajo nivel educativo.MaestríaMagister en Salud Public

Consecutive renal biopsy in a cohort of patients with lupus nephritis of the Colombian Caribbean

Background: Renal biopsy is the gold standard for the diagnosis and classification of lupus nephritis (LN). However, a consecutive biopsy can predict the clinical course and optimize the therapeutic strategies. Objectives: To compare the histopathological findings with clinical responses. Patients and Methods: Thirty patients with active LN were included. Renal biopsies were performed at the time of diagnosis and subsequently under clinical criteria according to consensus of Spanish Society of Nephrology. The response to treatment was defined as complete response, partial responder or non-responder. The histological change in second biopsy towards LN classes I, II or III/IV-C was defined as histological response (HR). Results: In initial renal biopsy, 28 (93%) patients showed proliferative LN; III-A or A/C (n; 7), IV-A or A/C (n: 19) and mixed; III+IV/V (n; 2). LN class V was presented in two cases. The clinical response was; complete response (10%), partial response (20%), and non-response (70%). HR was manifested in 37% and non-histologic response in 63% of patients. Around 33% of patients with complete response/partial response showed active lesions in the consecutive renal biopsy. Conclusions: In Colombian Caribbean, LN is aggressive and refractory to treatment. The consecutive renal biopsy allowed to demonstrate the persistence of the activity of the lesion in almost half of the patients, which may provide additional information to create better response criteria. The consecutive renal biopsy is a tool that allows improving the evaluation of the response to treatment in the LN

MicroRNAs overexpressed in Crohn's disease and their interactions with mechanisms of epigenetic regulation explain novel aspects of Crohn's disease pathogenesis

Background In this review, we were interested to identify the wide universe of enzymes associated with epigenetic modifications, whose gene expression is regulated by miRNAs with a high relative abundance in Crohn's disease (CD) affected tissues, with the aim to determine their impact in the pathogenesis and evolution of the disease. Methods We used HMDD and Bibliometrix R-package in order to identify the miRNAs overexpressed in CD. The identified enzymes associated with epigenetic mechanisms and post-translational modifications, regulated by miRNAs upregulated in CD, were analyzed using String v11 database. Results We found 190 miRNAs with great abundance in patients with CD, of which 26 miRNAs regulate the gene expression of enzymes known to catalyze epigenetic modifications involved in essentials pathophysiological processes, such as chromatin architecture reorganization, immune response regulation including CD4+ T cells polarization, integrity of gut mucosa, gut microbiota composition and tumorigenesis. Conclusion The integrated analysis of miRNAs with a high relative abundance in patients with CD showed a combined and superimposed gene expression regulation of enzymes associated with relevant epigenetic mechanisms and that could explain, in part, the pathogenesis of CD

Integrated analysis of microRNA regulation and its interaction with mechanisms of epigenetic regulation in the etiology of systemic lupus erythematosus

The aim of this study was to identity in silico the relationships among microRNAs (miRNAs) and genes encoding transcription factors, ubiquitylation, DNA methylation, and histone modifications in systemic lupus erythematosus (SLE). To identify miRNA dysregulation in SLE, we used miR2Disease and PhenomiR for information about miRNAs exhibiting differential regulation in disease and other biological processes, and HMDD for information about experimentally supported human miRNA-disease association data from genetics, epigenetics, circulating miRNAs, and miRNA-target interactions. This information was incorporated into the miRNA analysis. High-throughput sequencing revealed circulating miRNAs associated with kidney damage in patients with SLE. As the main finding of our in silico analysis of miRNAs differentially expressed in SLE and their interactions with disease-susceptibility genes, post-translational modifications, and transcription factors; we highlight 226 miRNAs associated with genes and processes. Moreover, we highlight that alterations of miRNAs such as hsa-miR-30a-5p, hsa-miR-16-5p, hsa-miR-142-5p, and hsa-miR-324-3p are most commonly associated with post-translational modifications. In addition, altered miRNAs that are most frequently associated with susceptibility-related genes are hsa-miR-16-5p, hsa-miR-374a-5p, hsa-miR-34a-5p, hsa-miR-31-5p, and hsa-miR-1-3p

Case-Serie of 4 COVID-19 patients hospitalized in an intensive care unit in a hospital institution in Barranquilla, Colombia

Objetivo: Presentar una serie de casos de COVID-19 con requerimiento de ingreso a Unidad de Cuidados Intensivos. Métodos: La información fue tomada de las historias clínicas, y su evaluación y diagnóstico fue realizado mediante estudios paraclínicos en sangre, orina, PCR e imágenes diagnósticas en 4 pacientes con diferentes comorbilidades y nexo epidemiológico presente para desarrollo de la enfermedad. El caso 1 desarrolló falla orgánica múltiple, incluyendo injuria renal aguda con una estancia en UCI de 4 dias antes de su fallecimiento, mientras los casos 2, 3 y 4 tuvieron una evolución favorable y fueron dados de alta de UCI. Los cuatro casos fueron manejados con cloroquina 300 mg via oral cada 12 horas y azitromicina 1 gr via oral cada 24 horas durante 5 dias sin complicaciones ni toxicidad asociada. Conclusiones: Se requieren estudios multicéntricos rápidos que orienten científicamente hacia un mejor abordaje diagnóstico y manejo, en el contexto de una enfermedad con un comportamiento clínico-epidemiologico que debe estudiarse en profundidad y que probablemente cobrará muchas vidas, ademas, debido a la ausencia de pruebas diagnósticas rápidas, la utilización de una clasificación basada en la severidad de lesiones radiológicas llamada CO-RADS (Covid-19 Imaging Reporting and Data System), podría ser de gran importancia para instalar de manera temprana los tratamientos farmacológicos disponibles y la asistencia respiratoria mecánica precoz.Objective: To present a COVID-19 case series with clinical admission criteria to Intensive Care Unit. Methods: Patients information was obtained from medical records, and daily clinical evaluation whereas diagnosis was carried out through paraclinical studies in blood, urine, PCR and diagnostic images in 4 patients with different comorbidities and epidemiological link for the development of COVID19. The case 1 developed multiple organ failure, including acute kidney injury with an ICU stay of 4 days before his death, while cases 2, 3 and 4 had a favorable evolution and were discharged from the ICU. All four cases were managed with chloroquine 300 mg orally every 12 hours and azithromycin orally every 24 hours for 5 days without complications or associated toxicity. Conclusions: rapid multicenter studies are required to scientifically guide a better diagnostic and management approach, in the context of a disease with a clinical-epidemiological behavior that must be studied in depth and will probably take many lives. In addition, due to the absence of sufficiently rapid tests, the use of a classification based on the severity of radiological lesions called CO-RADS (Covid-19 Imaging Reporting and Data System), could be of great importance to install av

La evolución

A manera de introducción citaremos un fragmento del libro del físico químico Peter Atkins de Oxford, con su interesante libro la creación, en el cual dice: Llevaré tu mente a un viaje. Es un viaje de entendimiento, que nos llevará al borde del espacio, el tiempo y la comprensión. Durante el mismo discutiré que no hay nada que no pueda ser comprendido, que no hay nada que no pueda ser explicado y que todas las cosas son extraordinariamente simples... Una gran parte del universo no necesita ninguna explicación. Por ejemplo, los elefantes. Una vez que las moléculas han aprendido a competir y a crear otras moléculas a su propia imagen, los elefantes y las cosas que son como los elefantes se encontrarán, a su debido tiempo, vagando por los campos. En este trabajo trataremos, un tema muy complejo y de por si muy extenso, abarcarlo todo en tan solo unas páginas es más que imposible. La evolución es un tema muy discutido, son muchas las corrientes que surgen a su alrededor alternativas, científicas, e incluso la religión está relacionada con este tema. El hombre siempre ha querido conocer sus orígenes, dando hipótesis, teorías, religiones, dogmas, mitos y leyendas. Pero la discusión está latente y seguirá así por muchos años. Quiénes somos y de dónde venimos? Una incógnita universal que siempre estará en las mentes de los hombres. Antes de empezar aclararemos que la teoría que nos parece más satisfactoria, es la Selección Natural de Darwin que expondremos en este trabajo de investigació

The Impact of Ketoanalogues on Nephropathy Progression in Advanced Chronic Kidney Disease Older Patients

Advanced chronic kidney disease (CKD) can be treated with conservative care or renal replacement therapies. CKD is associated with an increased risk of nephropathy progression, and death. Therefore, slow down CKD progression is crucial, and there is consensus regarding protein intake regulation benefit in delaying this progression. Ketoanalogues are nitrogen-free analogs of essential amino acids which supplements low protein diets. Thus, it was decided to evaluate if keto diet had benefit in reducing CKD progressio

Amiloidosis Renal: Reporte de un Caso y Revisión de Tema

Se designa con el nombre de amiloidosis a un grupo de enfermedades poco frecuentes, que se caracterizan por el depósito extracelular de un material proteico fibrilar denominado amiloide. La afectación renal en la amiloidosis sistémica es frecuente, por lo que se le asocia un pronóstico desfavorable, al ser la falla renal la segunda causa de muerte en los pacientes que la presentan. El objetivo de este trabajo consistió en presentar el caso de un hombre de 55 años, hipertenso de novo, con cuadro clinico de 7 meses de evolución de edema progresivo asociado a disnea, oliguria y hematuria, documentándose síndrome nefrótico en paraclínicos. El reporte histopatológico reveló acumulación de material eosinofílico rojo congo positiva a nivel glomerular, e inmunofluoresencia positiva para cadenas livianas en patrón mesangial, compatible con amiloidosis renal. La amiloidosis sigue siendo un desafío para los clínicos, en cuanto a su diagnóstico y tratamiento, y el pronóstico empeora a medida que se comprometen más órganos. La principal causa de muerte de los pacientes con amiloidosis obedece a trastornos cardiacos, siendo la segunda causa la falla renal.ABSTRACTA group of rare diseases are called amyloidosis. It is characterized by extracellular fibrillar protein material named amyloid deposit. Renal involvement in systemic amyloidosis is often, giving an unfavorable prognostic, being this one the second death cause in these kind of patients. It aims to show a 55 years old man, hypertensive with a clinical history of 7 months with a progressive edema associated with dyspnea, oliguria and hematuria, reporting nephrotic syndrome in paraclinical patients. The histopathological report reveals accumulation of Congo red coloured material positive in glomerular level and positive iimmune-fluorescence for light chains in mesangial pattern associated with renal Amyloidosis. Amyloidosis is still a challenge for clinical patients. based on its diagnosis and treatment. The prognosis is even worst as more organs are committed. It should be considered that the main cause of death of an amyloidosis patient is cardiac disorders, being renal failure the second cause of death

Síndrome nefrótico secundario a podocitopatía en infección por SARS-COV2

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is characterized by pulmonary involvement. However, there are reports on patients also suffering from concomitant renal involvement, with clinical manifestations such as hematuria, proteinuria, elevated nitrogen levels and acute kidney injury. Objective: The present study reports two clinical cases of nephrotic syndrome associated with coronavirus disease (COVID-19). Clinical case presentation: Histological imaging by electron microscopy showed, in one case, evidence of minimal changes and fusion of podocytes pedicels, and in the other one, podocytopathy with pedicels loss (70%) and focal sclerosis of capillary loops. Discussion: Proteinuria in COVID-19 can be secondary to glomerular and acute tubular lesions, with a multifactorial origin: Hemodynamic factors, cytokine storms, secondary infections, drug-induced nephrotoxicity and direct viral infection (proximal tubule cells and podocytes). The latter mechanisms could be explained by SARS-CoV2 renal tropism. Conclusion: The present report presents two cases of nephrotic syndrome secondary to podocytopathy in patients suffering from acute COVID-19 infection.Introducción: el síndrome respiratorio agudo severo inducido por coronavirus-2 (SARS-CoV-2) se caracteriza por la instalación de una afectación pulmonar. Sin embargo, existen reportes de afectación renal concomitante, con manifestaciones clínicas como hematuria, proteinuria y daño renal agudo. Objetivo: presentamos dos casos clínicos de síndrome nefrótico asociado a enfermedad por coronavirus (COVID-19). Presentación del caso: un paciente presentó evidencia histológica de cambios mínimos y fusión de pedicelos de podocitos en muestras histológicas evaluadas por microscopía electrónica. Discusión: la proteinuria en  COVID-19 puede ser secundaria a lesiones glomerulares y tubulares agudas, con un origen multifactorial: factores hemodinámicos, tormentas de citocinas, infecciones secundarias, nefrotoxicidad inducida por fármacos e infección viral directa de las células del túbulo proximal y podocitos. Esta última podría deberse a una infección directa por el virus debido al mayor tropismo renal de este. Conclusión: el presente informe presenta dos casos de síndrome nefrótico secundario a podocitopatía en pacientes con infección aguda por COVID-19
