  • Helicobacter pylori en agua potable ¿Es la ruta de la
           infección'

    •  
  • Randomized and controlled clinical trial of the effect of cocoa
           consumption in patients with insulin resistance

    • Abstract: Resumen Objetivo: determinar el efecto del consumo de cacao en pacientes con sindrome metabólico. Diseño: se realizó un ensayo clínico aleatorizado, de grupos paralelos, controlado con placebo, prospectivo, doble enmascarado. Pacientes: personas entre 18 y 70 anos de edad, no diabéticos, con resistencia a la insulina. Intervención: durante ocho semanas se evaluó el efecto del consumo de 50 g de chocolate rico en polifenoles, el grupo control recibió placebo. Mediciones: al inicio y al final del estudio el índice HOMA-IR, circunferencia abdominal, índice de masa corporal (IMC), glucemia y perfil lipídico. Resultados: en el grupo experimental (n=37) hubo reducción del HOMA IR (3.24 inicial y 2.77 final, p= 0.02), reducción del peso corporal, en promedio 1.53 Kg (inicial 86.3 Kg y final de 84.8 Kg, p=0.002), disminución del IMC (34.3 Kg/m2 al inicio y 33.5 Kg/m2 al final, p= 0.0001) y disminución de la cintura abdominal (inicial 106.3 cm y final 102.5 cm, p= 0.0001). Al comparar los resultados del grupo tratado con chocolate negro con los del grupo control (n=38) hubo diferencia estadísticamente significativa en la media de cintura abdominal al final entre ambos grupos (102.5 cm para el experimental y 108.0 cm para el control, p=0.01). Conclusiones: este ensayo sugiere que el consumo de 50 gramos diarios de chocolate rico en sólidos de cacao durante ocho semanas se asocia con una disminución de la circunferencia abdominal y el índice HOMA-IR. Además, aporta una evidencia de mayor calidad que los estudios observacionales sobre el uso de cacao en la reducción de la obesidad, la adiposidad y en la prevención de la enfermedad cardiometabólica en pacientes colombianos. (Acta Med Colomb 2017: 42: 90-96). Registro en Clinical Trials: NCT03034291 Objective: to determine the effect of cocoa consumption in patients with metabolic syndrome. Design: a randomized, parallel-group, placebo-controlled, prospective, double-masked clinical trial was conducted. Patients: people between 18 and 70 years of age, non-diabetic, with insulin resistance. Intervention: the effect of consumption of 50 g of chocolate rich in polyphenols was evaluated for eight weeks. The control group received placebo. Measurements: at the beginning and at the end of the study, the HOMA-IR index, abdominal circumference, body mass index (BMI), blood glucose and lipid profile. Results: in the experimental group (n = 37) there was a reduction of HOMA IR (3.24 initial and 2.77 final, p = 0.02), reduction of body weight, on average 1.53 Kg (initial 86.3 Kg and final 84.8 Kg, p = 0.002), decreased BMI (34.3 at baseline and 33.5 at end, p = 0.0001) and decreased abdominal waist (initial 106.3 cm and final 102.5 cm, p = 0.0001). When comparing the results of the group treated with black chocolate with those of the control group (n = 38), there was a statistically significant difference in the mean abdominal waist at the end between both groups (102.5 cm for the experimental group and 108.0 cm for the control, p = 0.01). Conclusions: This study suggests that consumption of 50 grams of chocolate rich in cocoa solids daily for eight weeks is associated with a decrease in waist circumference and the HOMA-IR index. In addition, it provides evidence of higher quality than observational studies on the use of cocoa in the reduction of obesity, adiposity and in the prevention of cardiometabolic disease in Colombian patients.

  • Association of clinical variables of hypoperfusion with lactate and
           mortality

    • Abstract: Resumen Introducción: entre los pacientes con infección la hiperlactatemia identifica una población de mayor gravedad. Este estudio pretende determinar en pacientes de urgencias la correlación y asociación entre los parámetros clínicos de perfusión y los valores de lactato en el momento de admisión; así como el cambio en los parámetros clínicos con la depuración del lactato. Además, determinar la asociación entre estas variables y la mortalidad intrahospitalaria. Métodos: cohorte prospectiva de pacientes que ingresaron con sospecha de infección a un hospital de tercer nivel. Se midió el lactato en la admisión a las 6 y 24 horas, concomitantemente con las variables llenado capilar, índice de choque y presión de pulso, entre otras. Se realizó correlación de Spearman entre las variables clínicas, los niveles de lactato y su depuración; así como curvas ROC para determinar la capacidad discriminativa de las variables clínicas para detectar hiperlactatemia. Se realizó un modelo de regresión logística multivariable para mortalidad. Resultados: se evaluaron 2257 pacientes, 651 correspondían a infección confirmada. No se encontró ninguna correlación de utilidad entre las variables clínicas y el lactato (r<0.25); y tampoco se detectó adecuada capacidad discriminativa para la detección de hiperlactatemia con ninguna variable clínica (AUC<0.61). En el modelo de regresión logística multivariada el valor del lactato al ingreso fue la única variable que se asoció de manera independiente con mortalidad (OR=1.4, IC95%=1.3-1.6). Conclusiones: entre los pacientes que ingresan a urgencias con infección no se encontró correlación entre las variables clínicas y el lactato; sin embargo, el lactato al ingreso es un marcador pronóstico independiente de mortalidad. (Acta Med Colomb 2017: 42: 97-105). Introduction: among patients with infection, hyperlactatemia identifies a population of greater severity. This study aims to determine the correlation and association between clinical perfusion parameters and lactate values in emergency patients at the time of admission, as well as the change in clinical parameters with lactate clearance. In addition, to determine the association between these variables and in-hospital mortality. Methods: Prospective cohort of patients admitted with suspected infection to a third level hospital. Lactate was measured at admission, at 6 and 24 hours, concomitantly with the variables capillary filling, shock index and pulse pressure, among others. Among the clinical variables, Spearman correlation, lactate levels and their clearance, as well as ROC curves to determine the discriminative ability of clinical variables to detect hyperlactatemia were performed. A multivariate logistic regression model for mortality was carried out. Results: 2257 patients were evaluated. 651 were confirmed with infections. No utility correlation was found between clinical variables and lactate (r <0.25), and no discriminative capacity was detected for the detection of hyperlactatemia with any clinical variable (AUC <0.61). In the multivariate logistic regression model the lactate value at admission was the only variable that was independently associated with mortality (OR = 1.4, 95% CI = 1.3-1.6). Conclusions: no correlation was found between clinical variables and lactate among patients admitted to the emergency department with infection; however lactate at admission is an independent prognostic marker of mortality.

  • Observed versus expected mortality in a network of dialysis units
           in Colombia

    • Abstract: Resumen Antecedentes: la mortalidad en diálisis es uno de los principales indicadores de gestión clínica y se ve influenciada por diversos factores sociodemográficos y clínicos. Objetivos: calcular la mortalidad observada versus la esperada en las unidades de diálisis de la red de RTS en Colombia. Métodos: cohorte histórica de pacientes mayores de 18 años, prevalentes en diálisis entre el 1 de enero y el 31 de diciembre de 2012, de 51 unidades renales de la red Renal Therapy Services (RTS). Se calculó la razón estandarizada de mortalidad (REM) siguiendo la metodología propuesta por la Universidad de Michigan Centro de Costos y Epidemiologic Renal (UM-KECC); se implementó un modelo de supervivencia de riesgos proporcionales de Cox en dos etapas, la primera estimó los parámetros asociados con las variables explicativas y la segunda estandarizó los resultados. Resultados: se evaluaron 9798 pacientes, 4125 (42.1%) fueron mujeres, la media de edad fue de 59 años (DE=15.6). Se observaron 1253 eventos de muerte (12.7%). El modelo arrojó un valor de 1067 muertes esperadas, con un valor estimado de REM de 1.17 (IC95%: 1.11-1.24). La REM fue mayor para pacientes diabéticos 1.28 (IC95%:1.19-1.38) y mujeres (1.36 (IC95%: 1.25-1.48); y varió significativamente por zona del país (1.11 a 2.0). Conclusiones: encontramos diferencias importantes en la REM según sexo, presencia de diabetes y por zonas del país. Se requiere mediante nuevos estudios entender mejor la influencia de estas y otras variables sobre el fenómeno de mortalidad en diálisis en nuestro contexto. (Acta Med Colomb 2017; 42: 106-111). Background: mortality in dialysis is one of the main indicators of clinical management and is influenced by various socio-demographic and clinical factors. Objectives: to calculate the observed versus expected mortality in the dialysis units of the RTS network in Colombia. Methods: a historical cohort of patients older than 18 years, prevalent on dialysis between January 1 and December 31, 2012, of 51 renal units of the Renal Therapy Services (RTS) network. The standardized mortality ratio (SMR) was calculated following the methodology proposed by the University of Michigan Center for Costs and Renal Epidemiology (UM-KECC); a Cox proportional hazards survival model was implemented in two stages, the first estimated the parameters associated with the explanatory variables and the second standardized the results. Results: 9798 patients were evaluated, 4125 (42.1%) were women. The mean age was 59 years (SD = 15.6). There were 1253 death events (12.7%). The model gave a value of 1067 expected deaths, with an estimated SMR value of 1.17 (95% CI: 1.11-1.24). SMR was greater for diabetic patients 1.28 (95% CI: 1.19-1.38) and women (1.36 (95% CI: 1.25-1.48)) and it varied significantly depending on the region of the country (1.11 to 2.0). Conclusions: important differences in SMR according to sex, presence of diabetes and by regions of the country were found. Further studies are required to better understand the influence of these and other variables on the mortality phenomenon in dialysis in our context. (Acta Med Colomb 2017; 42: 106-111).
       
  • Implementation of a security protocol in the administration of
           chemotherapy in the hematology Department of a fourth level hospital

    • Abstract: Resumen Objetivo: evaluar el conocimiento del personal e implementación del protocolo de seguridad en la administración de la quimioterapia en el servicio de Hematología del Hospital de San José. Material y métodos: la implementación fue evaluada por medio de listas de chequeo en cada proceso del protocolo y la evaluación del conocimiento por un cuestionario de 15 preguntas. Marco de referencia: servicio de Hematología del Hospital de San José, de Bogotá. Unidades de análisis: ciclos de quimioterapia administrados a pacientes adultos con diagnóstico de neoplasias hematológicas. Participantes: personal del servicio implicado en procesos de administración de quimioterapia. Mediciones: con las historias clínicas se describieron las características demográficas de los pacientes, los incidentes del proceso de administración de quimioterapia y la adherencia al protocolo por parte del personal de salud. El cuestionario de evaluación fue diseñado por los autores. Resultados: en 291 ciclos de quimioterapia (129 pacientes) se presentaron 214 incidentes del proceso de administración de quimioterapia de un total de 4074 posibles (5.2%), de estos, 16 están directamente relacionados con el uso de los medicamentos. La adherencia a los procesos del protocolo oscilo entre 40.5 y 100%. El conocimiento del personal tuvo una mejoría leve al comparar las dos evaluaciones realizadas. Conclusiones: aunque no se alcanzó la adherencia esperada al protocolo, se logró una disminución de los incidentes en comparación con estudios previos institucionales. Se requiere un nuevo plan de mejoramiento para aumentar la adherencia e impactar en la seguridad de los pacientes. (Acta Med Colomb 2017; 42: 112-120). Objective: assess staff knowledge and implementation of the security protocol in the administration of chemotherapy in the hematology department at the San Jose Hospital, Bogota. Material and methods: the implementation was evaluated through checklists in each protocol process and the knowledge evaluation by a15 questions questionnaire. Reference frame: hematology department of the San Jose Hospital, Bogota. Units of analysis: chemotherapy cycles administered to adult patients with diagnosis of hematologic malignancies. Participants: service personnel involved in chemotherapy administration processes. Measurements: the patient's demographic characteristics, the incidents of the chemotherapy administration process and adherence to the protocol by the health personnel were described with the medical records.
      Authors designed the evaluation questionnaire. Results: in 291 chemotherapy cycles (129 patients) there were 214 incidents of the chemotherapy administration process out of a total of 4074 possible (5.2%), of which 16 are directly related to the use of the drugs. Adherence to protocol processes ranged from 40.5 to 100%. Staff knowledge had a slight improvement when comparing the two evaluations performed. Conclusions: although the expected adherence to the protocol was not achieved, a decrease in incidents was obtained compared to previous institutional studies. A new improvement plan is required to increase adherence and achieve greater impact on patient safety. (Acta Med Colomb 2017; 42: 112-120).
       
  • Detection of Helicobacter pylori in water and biofilm samples from faucets
           of official educational institutions in the city of Medellin

    • Abstract: Resumen Introducción: Helicobacter pylori (Hp) es uno de los agentes infecciosos etiológico de la gastritis crónica, el linfoma de MALT, el adenocarcinoma gástrico y del cáncer gástrico y puede ser transmitido a través del agua. Objetivo: determinar la presencia de Hp por medio de cultivos y PCR en muestras de agua y biopelícula de los grifos de las instituciones educativas oficiales de la ciudad de Medellín, y la presencia de algunos factores de riesgo para la contaminación del agua. Material y métodos: en 194 instituciones educativas del municipio de Medellín, 2010-2011, se tomó una muestra de agua y biopelícula del grifo, las cuales se sembraron en agar HPSPA y se les realizó una prueba de PCR directa convencional con el gen ureA. Además, se realizó una encuesta para evaluar factores de riesgo como antigüedad de la edificación, estado físico y material de los grifos, presencia de tanques o pozos de agua para consumo, disponibilidad de agua potable y disponibilidad de fuentes de agua diferentes a las del acueducto municipal. Resultados: la frecuencia de ADN de Hp por la prueba de PCR en agua y biopelículas fue del 2.1% en cada tipo de muestra y por cultivo fue de 11.3% tanto en agua como en biopelícula. Las muestras de agua positivas por PCR correspondieron a las instituciones educativas ubicadas en Manrique, Villa Hermosa, San Javier y Guayabal, Las muestras de biopelículas positivas estuvieron en los barrios Popular, Villa Hermosa, Palmitas y en Santa Elena. Conclusiones: Hp fue detectado en las muestras de agua y biopelícula obtenidas de las instituciones educativas oficiales de Medellín y se pudo determinar por cultivo en HPSPA y por PCR con el gen ureA. Sin embargo, ninguno de los factores de riesgo estudiados fueron predictores para la contaminación. (Acta Med Colomb 2017; 42: 121-128). Introduction: Helicobacter pylori (Hp) is one of the etiological infectious agents of chronic gastritis, MALT lymphoma, gastric adenocarcinoma and gastric cancer and can be transmitted through water. Objective: to determine the presence of Hp by means of cultures and PCR in samples of water and biofilm of the faucets of the official educational institutions of the city of Medellin, and the presence of some risk factors for water contamination. Material and methods: In 194 educational institutions of the municipality of Medellin, 20102011, a sample of water and biofilm of faucet was taken and planted on HPSPA agar and a conventional direct PCR test was performed with the ureA gene. In addition, a survey to evaluate risk factors such as age of the building, physical and material condition of faucets, presence of water tanks or wells for consumption, availability of drinking water and availability of water sources other than those of the municipal aqueduct was carried out. Results: the frequency of Hp DNA by PCR test in water and biofilms was 2.1% in each type of sample and by culture was 11.3% in both water and biofilm. The positive water samples by PCR corresponded to the educational institutions located in Manrique, Villa Hermosa, San Javier and Guayabal. Positive biofilm samples were found in Popular, Villa Hermosa, Palmitas and Santa Elena districts. Conclusions: Hp was detected in the water and biofilm samples obtained from the official educational institutions of Medellin and could be determined by culture in HPSPA and by PCR with the ureA gene. However, none of the risk factors studied were predictors of contamination. (Acta Med Colomb 2017; 42: 121-128).
       
  • Service of humanism and bioethics of the Fundación Santa Fe de Bogota,
           Colombia. Two years of experience

    • Abstract: Resumen Para dar continuidad a una serie de actividades encaminadas a promocionar el trato respetuoso y humano en la Fundación Santa Fe de Bogotá, se creó un Servicio de Humanismo y Bioética a partir de octubre de 2013. Este servicio busca dar respuesta a las inquietudes y dificultades que los profesionales de la salud enfrentan día a día en la atención de pacientes y familias en una institución de salud altamente tecnificada. Igualmente, complementa las actividades que se realizan en los diferentes comités institucionales, buscando estrategias que permitan construir una mejor relación entre los pacientes y los profesionales clínicos, facilitando así la toma de decisiones y la mediación en los conflictos que puedan presentarse a la cabecera del paciente. Se está trabajando inicialmente en un programa de educación y de asesoría en bioética clínica para fomentar el pensamiento bioético y para aprender a reconocer cuestiones éticas que complementen la práctica médica altamente tecnificada y redunden en una atención humana y respetuosa de los pacientes y sus familias. (Acta Med Colomb 2017; 42: 129-135). In order to continue a series of activities aimed at promoting respectful and humane treatment at the Fundación Santa Fe de Bogota, a Humanism and Bioethics Service was created since October 2013. This service seeks to respond to the concerns and difficulties that Health professionals face day-to-day in the care of patients and families in a highly qualified health institution. It also complements the activities carried out in the different institutional committees, seeking strategies to build a better relationship between patients and clinicians, thus facilitating decision-making and mediation in conflicts that may arise at the patient's bedside. Initially, we are working on an educational and clinical bioethics advisory program to promote bioethical thinking and to learn to recognize ethical issues that may complement highly qualified medical practice that result in human and respectful care for patients and their families.

  • Nephrotic syndrome secondary to membranoproliferative glomerulonephritis
           due to Sjögren's syndrome

    • Abstract: Resumen El síndrome de Sjögren (SS), enfermedad autoinmune crónica, primaria o secundaria a otros desórdenes inmunológicos. La prevalencia es 0.05-0.23%, relación hombre: mujer 1:9, grupo etáreo 52-72 años. La afectación renal en el SSP (primario) puede ocasionar compromiso glomerular y/o tubular. Reportamos el caso de un hombre de 56 años, previamente sano que presentó síndrome nefrótico en el contexto de una glomerulonefritis membranoproliferativa (GMNMP), se diagnosticó SS con compromiso glomerular y se realizó revisión de la literatura. (Acta Med Colomb 2017; 42: 136-139). Sjögren's syndrome (SS) is a chronic autoimmune disease primary or secondary to other immunological disorders. The prevalence is 0.05-0.23%, male: female ratio 1:9, age group 52-72 years. Renal involvement in primary SS can lead to glomerular and/or tubular involvement. The case of a 56-year-old man previously healthy that presented nephrotic syndrome in the context of a membranoproliferative glomerulonephritis (MPGN) and was diagnosed with SS with glomerular involvement is reported, and a literature review was performed.

  • Acute porphyria. Diagnostic dilemma and neuroendocrine manifestations

    • Abstract: Resumen La porfiria intermitente aguda (PIA) es una enfermedad poco frecuente, considerada huérfana, que se caracteriza por crisis neuroviscerales, el dolor abdominal siendo su síntoma más común, acompañado en muchos casos, de síntomas inespecíficos, haciendo difícil su diagnóstico temprano. El retraso en el diagnóstico y tratamiento de esta entidad puede resultar catastrófico o incluso fatal, provocando daño neurológico a largo plazo o permanente. Reportamos el caso de un adulto joven que consulta en varias ocasiones por dolor abdominal inespecífico y 24 horas después de la admisión desarrolla inestabilidad autonómica simpática con cifras tensionales elevadas y taquicardia. Posteriormente debilidad muscular que evoluciona hasta cuadriplejia e hiponatremia con criterios para secreción inadecuada de hormona antidiurética (SIADH). Estos datos, junto con coloración rojiza en orina, llevan al diagnóstico de porfiria. Presentamos las características clínicas y bioquímicas enfatizando la importancia de incluir la porfiria dentro de los diagnósticos diferenciales de dolor abdominal y disautonomia de causa indeterminada. (Acta Med Colomb 2017; 42: 140-143). Acute intermittent porphyria (AIP) is an infrequent and considered orphan disease, characterized by neurovisceral crisis, being abdominal pain the most common symptom, accompanied in many cases by non-specific symptoms, making early diagnosis difficult. The delay in the diagnosis and treatment of this entity can be catastrophic or even fatal, causing long-term or permanent neurological damage. The case of a young adult who attends medical consultation several times for non-specific abdominal pain and 24 hours after admission develops sympathetic autonomic instability with elevated blood pressure and tachycardia is presented. He subsequently presents muscular weakness that evolves to quadriplegia and hyponatremia with criteria for inadequate secretion of antidiuretic hormone (SIADH). These data together with reddish urine staining lead to the diagnosis of porphyria. The clinical and biochemical characteristics emphasizing the importance of including porphyria within the differential diagnoses of abdominal pain and dysautonomia of indeterminate cause are presented.
