Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Association between the start time of non-invasive mechanical ventilation in patients with cariogenic pulmonary edema and in-hospital mortality at the Hospital Universitario San Vicente Fundacion. Retrospective cohort study, with instrumental variable

Resumen: Contexto: El edema pulmonar cardiogénico (EPC) es una entidad con alta morbi-mortalidad y para su tratamiento se cuenta con múltiples herramientas farmacológicas y médicas, entre ellas la ventilación mecánica no invasiva (VMNI) sin embargo, no es claro en qué momento de la atención debe iniciarse, para obtener mejores resultados. Objetivo: Evaluar la posible asociación entre el tiempo de inicio de la VMNI desde el ingreso al servicio de urgencias con la mortalidad y el requerimiento de intubación entre pacientes hospitalizados por EPC. Metodología: Se desarrolló un estudio observacional analítico de cohorte retrospectiva. La muestra fue a conveniencia, incluyendo aquellos individuos que consultaron al servicio de urgencias del Hospital Universitario San Vicente Fundación (HUSVF) con diagnóstico de EPC entre enero de 2013 y abril de 2018. A las variables cuantitativas se les calculó porcentajes y rangos, a las variables cualitativas se les calculó frecuencias absolutas y relativas; por último, se realizó una regresión logística analizando OR ajustado entre tiempo de inicio de la intervención y mortalidad, donde se exploró un modelo explicativo, además de usar el método de variables instrumentales (VI) con el objetivo de controlar los posibles factores de confusión y errores de medición. Resultados: De 1517 pacientes preseleccionados, 70 cumplieron los criterios de inclusión y sus características fueron comparadas según el estado vital al alta. En cuanto a los vivos (49 pacientes): promedio de edad 63 años, 34.7 % eran mujeres, 57.1 % tenían el antecedente de neumopatía crónica, 89 % eran hipertensos y en promedio recibieron la intervención a las 10 horas desde el ingreso y 20 % requirieron intubación orotraqueal. Respecto a los muertos (21 pacientes): promedio de edad 74 años, 57.1 % eran mujeres, 57.1 % tenían el antecedente de neumopatía crónica, 90 % eran hipertensos; en promedio recibieron VMNI a las 7 horas desde el ingreso y 62 % requirieron intubación orotraqueal. El tiempo de inicio de VMNI en relación con mortalidad: OR=1.05; IC 95 % = 0.89; 1.24, p 0.499 y el método de VI arrojó un 7 % de proporción absoluta de morir para quienes se identificó un mayor tiempo en el inicio de la VMNI. En cuanto al tiempo de inicio de VMNI y su asociación con la necesidad de intubación endotraqueal no se logró identificar una relación clara (OR= 0.93; IC 95 %= 0.86; 1.01). Limitaciones: Registros incompletos en historias clínicas sobre el uso de modalidad de VMNI, desconocimiento de la etiología de EPC y el tamaño de muestra la cual fue insuficiente para encontrar diferencias significativas, sin embargo, se lograron explorar hipótesis sobre el inicio de VMNI con mortalidad y tasa de intubación orotraqueal. Conclusiones: La estimación puntual establece que el inicio tardío de la VMNI es un factor de riesgo, sin embargo, no se halló asociación estadísticamente significativa, lo que nos sugiere que se requieren de estudios adicionales que permitan confirmar este hallazgo.Context: Cardiogenic pulmonary edema (CPE) is an entity with high morbidity and mortality, and multiple pharmacological and medical tools are available for its treatment, including non-invasive mechanical ventilation (NIMV), however it is not clear at what point in care must be started for best results. Objective: To evaluate the possible association between the start time of NIMV from admission to the emergency department with mortality and the requirement for intubation among patients hospitalized for CPE. Methodology: An analytical observational retrospective cohort study was developed. The sample was for convenience, including those individuals who consulted the emergency service of the San Vicente Fundación University Hospital (HUSVF) with a diagnosis of CPE between January 2013 and April 2018. Percentages and ranges were calculated for the quantitative variables, the qualitative variables absolute and relative frequencies were calculated; Lastly, a logistic regression was performed, analyzing the adjusted OR between the start time of the intervention and mortality, where an explanatory model was explored, in addition to using the method of instrumental variables (VI) in order to control for possible confounding factors and measurement errors. Results: Of 1517 preselected patients, 70 met the inclusion criteria and their characteristics were compared according to vital status at discharge. Regarding the living (49 patients): average age 63 years, 34.7% were women, 57.1% had a history of chronic lung disease, 89% were hypertensive and on average received the intervention 10 hours after admission and 20% required orotracheal intubation. Regarding the dead (21 patients): average age 74 years, 57.1% were women, 57.1% had a history of chronic lung disease, 90% were hypertensive; On average, they received NIMV 7 hours after admission, and 62% required orotracheal intubation. The start time of NIMV in relation to mortality: OR = 1.05; 95% CI = 0.89; 1.24, p 0.499 and the LV method yielded a 7% absolute proportion of dying for those who identified a longer time at the start of NIMV. Regarding the time of initiation of NIMV and its association with the need for endotracheal intubation, it was not possible to identify a clear relationship (OR = 0.93, 95% CI = 0.86, 1.01). Limitations: Incomplete records in medical records on the use of NIMV modality, ignorance of the etiology of CPE and the sample size which was insufficient to find significant differences, however, it was possible to explore hypotheses about the initiation of NIMV with mortality and Orotracheal intubation rate. Conclusions: The point estimate establishes that late initiation of NIMV is a risk factor, however, no statistically significant association was found, suggesting that additional studies are required to confirm this findin

En este grupo de tumores se encuentran los meningiomas. Se narra un caso de meningioma en un paciente con antecedentes de hipertensión arterial no controlada. Se hace una revisión de la bibliografía de esta patología; epidemiología, clasificación, manifestaciones clínicas y tratamiento

White plague-like coral disease in remote reefs of the Western Caribbean

The health of coral reef communities has been decreasing over the last 50 years, due the negative effects of human activities combined with other natural processes. We present documentation of a White Plague Disease (WPD) outbreak in the Serrana Bank, an isolated Western Caribbean atoll with presumably inexistent pollutant inputs from local human settlements. In addition, this study summarizes seven years of observations on diseased corals in the nearby island of San Andrés, which in contrast is one of the most populated islands of the Caribbean. There was a massive coral mortality in the atoll lagoon (14°27’53.24", 80°14’22.27" W, and 12m depth) due to WPD on May 4 of 2003. Seventeen species were found dead or largely affected by the disease. The information resulting from GPS and manta-tow transects revealed that approximately 5.8ha of reticulate Montastraea spp. patch reefs were lethally affected by the disease in the atoll. On May 8 of the same year we observed and calculated a mean coral cover of 7.03% (SD± 2.44), a mean diseased coral tissue cover of 5.5% (SD± 1.1) and a 13.4% (SD± 8.05) of recently dead coral covered with a thin filamentous algae layer; approximately 73% of mortalities caused by the disease occurred before the end of the outbreak. A rough estimate of 18.9% in recent coral cover reduction can be attributed to WPD. This represents about 82% of the total coral cover decline since 1995. Semi-enclosed environments such as atoll lagoons and the reticulate patch-reefs of Montastraea spp. seem to be particularly vulnerable to this kind of coral disease, which constitute an alert to increase the monitoring of the same kind of atoll environments. The WPD has been present in the area of the nearby island of San Andrés at a low prevalence level, with sporadic increasing peaks of disease proliferation. The peaks observed during 1999 and 2004 comprised increases of 266% and 355% respectively, suggesting an alarming progression of the disease in this area. This study includes new information of the epizoolotiology of White Plague Disease and documents the permanent prevalence and progression of the WPD in the area of San Andres Island. Rev. Biol.

XX Curso de actualización en Medicina Interna

RESUMEN: En esta época donde cualquier información se viraliza masivamente, con algún tipo de lógica que apele a los temores naturales del ser humano como el miedo y la incertidumbre, hay presente un antídoto incontrovertible: la generación de conocimiento y su difusión de manera responsable. Este es uno de los roles fundamentales de la Universidad de Antioquia y en especial de su Facultad de Medicina en el siglo XXI; en torno a los procesos de construcción académica y científica, reivindicar su papel en el eje de la extensión universitaria, a través de la divulgación de contenidos de alto valor para que los estudiantes y médicos que atienden a la población tengan herramientas para tomar las mejores decisiones. Es por eso que el Departamento de Medicina Interna quiere continuar como actor clave en el despliegue de nuestra Facultad y su centro de extensión, más en las circunstancias actuales que nos obligan a buscar soluciones creativas. Por fortuna, la Universidad de Antioquia ha logrado desarrollar una interesante sinergia entre las nuevas tecnologías y la difusión del conocimiento, y disponemos de un gran número de profesores que se han unido a este esfuerzo, porque los problemas de salud además de la pandemia por COVID-19 no dan espera. Hemos preparado este curso tomando en cuenta que en el campo de la medicina interna existen agudas controversias que vale la pena reflexionar. También hay prácticas de alta calidad que es importante precisar ante la comunidad científica, y que plenamente avaladas por la evidencia es necesario aplicar en amplios contextos, desde la atención ambulatoria a la hospitalaria. Esperamos que los contenidos desarrollados en este texto y compartidos con ustedes en el ambiente virtual sean útiles para seguir aportando conocimiento de valor desde nuestra Alma Máter a toda la comunidad médica y estudiantilTABLA DE CONTENIDO Capítulo 1.

Psicología de las organizaciones y del trabajo. Apuestas de investigación II

El presente volumen condensa y sintetiza lo que va siendo contemporáneamente la POT colombiana, en particular, y latinoamericana, en general, que aparece como un reflejo y una adaptación de la que se está desarrollando globalmente según cánones dictados desde otras latitudes socioeconómicas, políticas y culturales, pero también como reacción a ella y como autoafirmación. Ello no constituye un ejemplar de texto anticolonial, sino más bien un manifiesto antietnocéntrico al presentar e interpretar la realidad investigada en el marco de sus propios parámetros socioculturales, sin que estos sean considerados necesariamente claves universales para la comprensión de otras realidades ajenas y exóticas. Y esta es una de sus principales contribuciones generales, porque marca un estilo distinto de hacer POT al enfatizar el aspecto idiosincrático de los fenómenos y procesos de que se ocupa y haciéndolo así, señala un horizonte que no deben perder de vista la disciplina y la profesión, si no quieren repetir viejos errores de su pasado reciente derivados de la minimización de la relatividad histórico-cultural de su campo y su objeto. A escala global y local, resta un largo camino por progresar hacia una POT con mayor fundamentación epistemológica, más articulación interdisciplinaria y multiprofesional, relevancia social, elaboración teórica, calidad y diversidad metodológicas y reflexividad autocrítica que resitúe en el centro del quehacer científico y profesional el marco de referencia axiológico, étho-politico y deontológico. Este libro es un paso significativo en esta dirección.Universidad de San Buenaventura - Cal
