Características clínicas predictoras de déficit de vitamina B12 de diabetes mellitus 2 tratada con metformina / Clinical characteristics of vitamin B12 deficiency predictors in metformin-treated type-2 diabetes mellitus

ntroducción: el consumo de metformina se asocia con déficit de vitamina B12. Objetivo: identificar las características clínicas predictoras del déficit en mayores de 18 años con diabetes mellitus tipo 2 (DM2) tratados con metformina. Materiales y métodos: estudio de corte transversal analítico en 100 pacientes entre 50 y 85 años con DM2 tratados con metformina por más de 3 meses, con registro de niveles de vitamina B12 en la historia clínica, atendidos en un programa de diabetes de medicina familiar en Bogotá DC, Colombia. Resultados: la media de duración de la enfermedad fue 9.6 años, el uso de metformina varió entre 1 y 5 años (32%), la dosis más utilizada estuvo entre 1001 y 2000 mg (65%), polifarmacia en 45% y la prevalencia del déficit en 27%. En el modelo de regresión logística se encontró que el tiempo de uso se comporta como factor predictor de déficit de vitamina B12 (OR=0,01 IC95% 0,01-0,03) (p<0,05), la polifarmacia (OR=1.21 IC95% -0,06-2,5) y la duración de la diabetes (OR=1.14 IC95% 0,99-1,32) emergen como factores predictores, pero sin diferencia estadísticamente significativa.Conclusión: el tiempo de uso de metformina es una característica clínica que puede ser predictora del déficit de vitamina B12, la prevalencia del déficit en nuestro estudio fue alta, consideramos recomendable realizar una búsqueda activa en la práctica clínica

ntroduction: the metformin use is related to vitamin B12 deficiency. Objective: to identify the clinical characteristics that predict B12 deficiency in metformin-treated type-2 diabetes mellitus (T2DM) patients, aged 18 years or older. Materials and methods: analytical cross-sectional study including 100 T2DM patients aged between 50 and 85 years, on metformin for more than 3 months, with vitamin B12 levels recorded in their clinical record, seen in a family medicine diabetes program in Bogotá DC, Colombia. Results: the median duration of the disease was 9.6 years, metformin use ranged between 1 and 5 years (32%), the most commonly used dose ranged between 1001 and 2000 mg (65%), polypharmacy was evidenced in 45% and B12 deficiency prevalence was 27%. The logistic regression analysis showed that time of metformin use behaved as a predictor of vitamin B12 deficiency (OR=0.01 CI95% 0.01-0.03) (p<0.05). Polypharmacy (OR=1.21 CI95% -0.06-2.5) and diabetes duration (OR=1.14 CI95% 0.99-1.32) emerged as predictor factors, but with no statistically significant difference. Conclusion:duration of metformin use is a clinical variable that can be a predictor of vitamin B12 deficiency. Prevalence of B12 deficiency was high in our study. We recommend an active search of this deficiency in clinical practice

Modifications in self-care, quality of life and therapeutic adherence in patients with rheumatoid arthritis during the SARS-CoV-2 pandemic treated by telehealth

Introduction: Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation, causing pain and stiffness in the joints. SARS-CoV-2 increases the clinical vulnerability of the population with RA and has led to the implementation and/or development of telemedicine. Objective: To describe changes in level of therapeutic adherence, quality of life and capacity for self-care agency, during the follow-up period of a group of patients linked to a non-face-to-face multidisciplinary consultation model during the SARS-CoV-2 pandemic. Methodology: Descriptive cohort study (July to October 2020). Description of the level of therapeutic adherence (Morisky Green Test), quality of life (EuroQOL-5-Dimensions-3-Level-version) and self-care capacity (ASA-R Scale) in the context of a telehealth model. A univariate and bivariate analysis was performed (Stata Software, Considered p-value <0.05). Results: Of 71 patients treated under the telehealth model, 85.9% were women, the age range was between 33 and 86 years with a median of 63. The most prevalent comorbidity was arterial hypertension (35.2%). Quality of life did not change during follow-up nor did adherence to treatment, apart from in one item [the patients did not stop taking the medication when they were well (p = 0.029)]. In self-care capacity, there were significant improvements in five dimensions (p < 0.05), without significant differences in the global score. Conclusion: Patients with RA evaluated in the context of telehealth in a period of pandemic did not present significant changes in quality of life, adherence to treatment, or capacity for self-care, and remained close to baseline values when they attended a traditional face-to-face assessment.

INTRODUCCIÓN: La artritis reumatoide (AR) es una enfermedad autoinmune caracterizada por una inflamación crónica que produce dolor y rigidez articular. El SARS-CoV-2 aumenta la vulnerabilidad clínica en pacientes con AR, lo que ha conllevado la implementación o el desarrollo de la telesalud. OBJETIVO: Describir los cambios en el nivel de adherencia terapéutica, la calidad de vida y la capacidad de autocuidado durante el periodo de seguimiento, en un grupo de pacientes con AR vinculados con un modelo de consulta multidisciplinar no presencial, en el curso de la pandemia por SARS-CoV-2. METODOLOGÍA: Estudio de cohorte descriptiva (julio a octubre del 2020). Descripción del nivel de adherencia terapéutica (TEST MORISKY GREEN), calidad de vida (EUROQOL-5-DIMENSIONS-3-LEVEL-VERSION) y capacidad de autocuidado (Escala ASA-R) en el contexto de un modelo de telesalud. Se realizó análisis univariado y bivariado (SOFTWARE Stata®, valor de p considerado <0,05). RESULTADOS: De 71 pacientes atendidos en modalidad de telesalud, el 85,9% fueron mujeres, la mediana de la edad fue de 63 (33-86) anos. La comorbilidad más prevalente fue la hipertensión (35,2%). La calidad de vida no tuvo cambios durante el seguimiento, al igual que la adherencia al tratamiento, excepto en uno de los ítems (los pacientes no dejaron de tomar la medicación cuando se encontraban bien; p = 0,029). En la capacidad de autocuidado hubo mejoras significativas en 5 dimensiones (p < 0,05), sin diferencias significativas en el puntaje global. CONCLUSIÓN: Los pacientes con AR evaluados en el contexto de la telesalud, en un periodo de pandemia, no presentaron cambios significativos en la calidad de vida, la adherencia al tratamiento y la capacidad de autocuidado; se mantuvieron en niveles similares a los valores basales cuando asistían a valoración tradicional presencial.

Evaluation of a Non-Face-to-Face Multidisciplinary Health Care Model in a Population with Rheumatoid Arthritis Vulnerable to COVID-19 in a Health Emergency Situation.

This study evaluated a non-face-to-face-multidisciplinary consultation model in a population with rheumatoid arthritis (RA) during the COVID-19 pandemic. This is an analytical observational study of a prospective cohort with simple random sampling. RA patients were followed for 12 weeks (Jul-Oct 2020). Two groups were included: patients in telemedicine care (TM), and patients in the usual face-to-face care (UC). Patients could voluntarily change the care model (transition model (TR)). Activity of disease, quality of life, disability, therapeutic adherence, and self-care ability were analyzed. Bivariate analysis was performed. A qualitative descriptive exploratory study was conducted. At the beginning, 218 adults were included: (109/TM-109/UC). The groups didn't differ in general characteristics. At the end of the study, there were no differences in TM: (n = 71). A significant (p < 0.05) decrease in adherence, and increase in self-care ability were found in UC (n = 18) and TR (n = 129). Seven patients developed COVID-19. Four categories emerged from the experience of the subjects in the qualitative assessment (factors present in communication, information and communication technologies management, family support and interaction, and adherence to treatment). The telemedicine model keeps RA patients stable without major differences compared to the usual care or mixed model.

Establishing an acquisition and processing protocol for resting state networks with a 1.5 T scanner: A case series in a middle-income country.

OBJECTIVE: The aim of this study was to characterize the capability of detection of the resting state networks (RSNs) with functional magnetic resonance imaging (fMRI) in healthy subjects using a 1.5T scanner in a middle-income country. MATERIALS AND METHODS: Ten subjects underwent a complete blood-oxygen-level dependent imaging (BOLD) acquisition on a 1.5T scanner. For the imaging analysis, we used the spatial independent component analysis (sICA). We designed a computer tool for 1.5 T (or above) scanners for imaging processing. We used it to separate and delineate the different components of the RSNs of the BOLD signal. The sICA was also used to differentiate the RSNs from noise artifact generated by breathing and cardiac cycles. RESULTS: For each subject, 20 independent components (IC) were computed from the sICA (a total of 200 ICs). From these ICs, a spatial pattern consistent with RSNs was identified in 161 (80.5%). From the 161, 131 (65.5%) were fit for study. The networks that were found in all subjects were: the default mode network, the right executive control network, the medial visual network, and the cerebellar network. In 90% of the subjects, the left executive control network and the sensory/motor network were observed. The occipital visual network was present in 80% of the subjects. In 39 (19.5%) of the images, no any neural network was identified. CONCLUSIONS: Reproduction and differentiation of the most representative RSNs was achieved using a 1.5T scanner acquisitions and sICA processing of BOLD imaging in healthy subjects.

Condiciones en la frontera sur entre Colombia y Venezuela ante la pandemia de COVID-19 / Underlying conditions on the southern border between Colombia and Venezuela to face the COVID-19 pandemic

RESUMEN Objetivos Dimensionar la migración humana en la frontera sur entre Colombia y Venezuela (Departamento de Guainía), y caracterizar las condiciones sociales, de acceso y de atención en salud frente a la pandemia de COVID-19. Métodos Estudio mixto, epidemiológico y etnográfico. Se calcularon: tasa de migrantes venezolanos (según Migración Colombia al 31 de diciembre de 2019), acceso efectivo a atención médica y dotación en puestos de salud (según datos recolectados entre junio de 2017 y julio de 2019, en todos los puestos de salud de Guainía, mediante entrevistas semiestructuradas, observación participante y el uso de Google Earth™ y Wikiloc™). Los tiempos medianos se calcularon y graficaron en Stata™. Se describieron dinámicas culturales y de atención en salud a partir del trabajo de campo y de una permanente revisión documental. Resultados Guainía ocupa el puesto 23 en número total de venezolanos, pero es el cuarto departamento en densidad de venezolanos (14,4%). En ausencia del centro de salud de San José, en el río Guainía los tiempos medianos hasta la institución de referencia real son de 8,7 horas en invierno y 12,3 en verano y los casos complejos requieren remisión aérea. En el río Inírida, sin el centro de Chorro Bocón, los tiempos reales son de 11,9 horas en invierno y 16,1 en verano. Solo el 57% de los puestos de salud tenía insumos para manejar infección respiratoria aguda. Conclusiones Ante la llegada de COVID-19 a territorios sur-fronterizos, es necesario fortalecer inmediatamente servicios médicos y de salud pública para evitar elevadas tasas de letalidad.(AU)

ABSTRACT Objectives To size human migration on the southern border between Colombia and Venezuela (Guainía department), and characterize the social, access and health care conditions relevant to the COVID-19 pandemic. Methods Mixed epidemiological and ethnographic study. Rate of Venezuelan migrants was calculated according to Migration Colombia data until December 31st, 2019, also effective access to medical care, and provision of health posts were calculated, with information from each Guainía health post collected from June 2017 to June 2019, through semi-structured interviews, participant observations, Google Earth™ and Wikiloc™. Stata™ was used to calculate and graph median times of effective access. Cultural dynamics and health care conditions were described by the field work information and a permanent documentary review. Results Guainía is the 23rd department, according to the total number of Venezuelans, but the fourth in Venezuelans density (14,4%). In the Guainía river, the median times to the real reference health institution were 8,7 hours in winter and 12,3 in summer, and complex cases require air referrals. In the Inírida river, the median times to the real reference health institution were 11,9 hours in winter and 16,1 in summer. Only 57% of the health posts had supplies for acute respiratory infections. Conclusions Facing COVID-19 in south border territories, it is necessary to immediately strengthen medical and public health services to avoid high fatality rates.(AU)

Pacientes procedentes de un territorio disperso que fallecieron en un hospital universitario: serie de casos / Patients from a scattered territory who died in a university hospital. A case series / Pacientes de um territorio disperso, que morreram em um hospital universitário. Série de casos

Introducción: Guainía, departamento con población dispersa, pluriétnico y multifronterizo, fue seleccionado en 2016 como piloto del Modelo Integral de Atención en Salud (MIAS). Dentro de la operación del MIAS se encuentra el Hospital de San José (HSJ), hospital universitario ubicado en Bogotá, que recibe pacientes remitidos por aire desde Guainía para atención especializada. Objetivo: Describir las características de los pacientes remitidos de Guainía que murieron en el HSJ, en el marco del MIAS. Métodos: Estudio tipo serie de casos de los pacientes procedentes de Guainía y remitidos al HSJ que fallecieron durante la estancia hospitalaria entre el 1 de julio de 2016 y el 31 de diciembre de 2017. Se analizaron variables demográficas y clínicas mediante estadística descriptiva. Para identificar muertes evitables se usó el inventario de indicadores de mortalidad evitable adaptado a Colombia (INIME). Resultados: De los 238 pacientes recibidos, 18 fallecieron, 3 de los cuales murieron antes de 48 horas de estancia hospitalaria. La mayoría requirió unidad de cuidado intensivo. Entre los diagnósticos de ingreso predominó la neumonía en el grupo de las patologías infecciosas y la desnutrición en las no infecciosas. Las muertes de todos los menores de 18 años y del 70 % de adultos tenían causas potencialmente evitables según los grupos del INIME. Discusión: El predominio de causas de mortalidad evitables, con muertes por desnutrición infantil y enfermedad diarreica aguda, indica la necesidad de actividades que impacten los determinantes sociales y la determinación social de la salud. Conclusión: La alta frecuencia de muertes evitables sugiere que la implementación de la estrategia de atención primaria en salud no fue óptima en el periodo estudiado. Además, para los casos graves, el estrés del desplazamiento aéreo a Bogotá no parece una buena opción. Es necesario incrementar las capacidades del Hospital de Inírida para reducir remisiones de casos.

Introduction: Guainía, a department with a dispersed, multi-ethnic and multi-border population, was selected in 2016 as a pilot of the Integral Model of Health Care (MIAS). Within the MIAS operation is the Hospital de San José (HSJ), a university hospital located in Bogotá, which receives air-remited patients from Guainía for specialized care. Objective: To describe the characteristics of Guainía patients who died in HSJ, under the MIAS. Methods: Serial case study of patients from Guainía referred to HSJ, who died during the hospital stay, between July 01, 2016 and December 31, 2017. Demographic and clinical variables were analyzed using descriptive statistics. The inventory of Colombia-adapted avoidable mortality indicators (INIME) was used to identify preventable deaths. Results: Of the 238 patients received, 18 died, 3 of them died before 48 hours of hospital stay. Most required Intensive Care Unit. Among the entrance diagnoses, pneumonia prevailed in the group of infectious pathologies and malnutrition in non-infectious ones. The deaths of all children under the age of 18 and 70 % of adults had potentially avoidable causes according to INIME groups. Discussion: The prevalence of preventable causes of mortality, with deaths from child malnutrition and acute diarrhoeal disease, indicates the need for activities that impact social determinants and social determination of health. Conclusion: The high frequency of avoidable deaths suggests that the implementation of the Primary Health Care strategy was not optimal in the period studied. Moreover, for severe cases, the stress of air travel to Bogotá does not seem like a good option. It is necessary to increase the capacities of Inírida Hospital to reduce critical case referrals.

As mortes de todos os menores de 18 e 70 % dos adultos tiveram causas potencialmente evitáveis, de acordo com os grupos do INIME. Discussão: A prevalência de causas evitáveis de mortalidade, com mortes por desnutrição infantil e doença diarréica aguda, indica a necessidade de atividades que impactem os determinantes sociais e a determinação da saúde social. Conclusão: A alta frequência de mortes evitáveis sugere que a implementação da estratégia de Atenção Primária à Saúde não foi ótima no período estudado. Além disso, em casos graves, o estresse nas viagens aéreas para Bogotá não parece ser uma boa opção.

[Quality of clinical practice guidelines published in nutrition in hospitalized oncological adult patients]. / Calidad de las guías de práctica clínica publicadas en nutrición de pacientes hospitalizados adultos oncológicos.

BACKGROUND: There is a high variability in clinical practice regarding nutritional care which could affect nutritional status of oncological patients. This variability can be diminished following evidence based recommendations from clinical practice guidelines (CPG) with good methodological quality in its development. OBJECTIVE: To review and evaluate the quality of published guidelines in nutrition in hospitalized oncological adult patients. METHODS: A search of CPGs was conducted in MEDLINE, EMBASE, GIN, TripDatabase and pages of recognized guidelines developers. CPGs published between 2003 and 2012 were included. Four independent reviewers assessed the quality of CPGs using the AGREE II instrument. Characteristics of assessed guidelines were extracted and analyzed. RESULTS: 22 CPGs met selection criteria. 90% of guidelines are written in English. There was great variability in quality scores for each domain. Highest rated domain was "clarity of presentation" (median 65.95, range 19.40 to 93.10) while the lowest was "Applicability" (median 21.20, range 0 to 77.10). Sixteen guidelines scored low on "rigour of development" and six had an acceptable or good quality. Only five documents can be considered as "good quality guidelines" because they showed high performance in all domains. CONCLUSION: It was found a wide range of methodological quality scores of evaluated CPGs. Highest rated guidelines are made by agencies that develop guidelines but these are little known in our country. Most of the assessed guidelines have methodological weaknesses, which can affect the quality of the recommendations they make and its validity.

Calidad de las guías de práctica clínica publicadas en nutrición de pacientes hospitalizados adultos oncológicos / Quality of clinical practice guidelines published in nutrition in hospitalized oncological adult patients

Introducción: Existe alta variabilidad en la práctica clínica en nutrición que podría afectar el estado nutricional del paciente oncológico. Esta variabilidad disminuye con el uso de recomendaciones válidas basadas en la evidencia proveniente de guías de práctica clínica (GPC) con adecuada calidad metodológica en su elaboración. Objetivo: Revisar y evaluar la calidad de las guías publicadas en nutrición de pacientes adultos oncológicos hospitalizados. Métodos: Una búsqueda de GPC fue realizada en MEDLINE, EMBASE GIN, TripDatabase y páginas de elaboradores reconocidos de guías. Se incluyeron guías basadas en la evidencia publicadas entre 2003 y 2012. Cuatro revisores independientes evaluaron la calidad de las GPC usando el instrumento AGREE II. Las características de las guías evaluadas fueron extraídas y analizadas. Resultados: Fueron seleccionadas 22 GPC. Un 90% de las guías están escritas en inglés. Hubo gran variabilidad en los puntajes de calidad de cada dominio. El dominio mejor puntuado fue "Claridad de la presentación" (mediana 65,95, rango 19,40-93,10) mientras que el más bajo fue "Aplicabilidad" (mediana 21,20, rango 0,077,10). Dieciséis guías puntuaron bajo en "Rigor metodológico" y seis presentaron una calidad aceptable o buena. Cinco GPC presentaron un alto desempeño en todos los dominios y fueron consideradas de alta calidad. Conclusión: Hubo un amplio rango de puntajes de calidad metodológica de las GPC. Las guías mejor puntuadas son elaboradas por entidades desarrolladores de guías, pero poco conocidas en nuestro medio. Muchas GPC presentan debilidades metodológicas que pueden afectar la calidad de las recomendaciones que emiten y por lo tanto su validez (AU)
