Abstract

Abstract Objectives The marine cyanobacterium Prochlorococcus is a critical part of warm ocean ecosystems and a model for studying microbial evolution and ecology. To expand the representation of this organism’s vast wild diversity in sequence collections, we performed a set of isolation efforts targeting low light-adapted Prochlorococcus. Three genomes resulting from this larger body of work are described here. Data description We present draft-quality Prochlorococcus genomes from enrichment cultures P1344, P1361, and P1363, sampled in the North Pacific. The genomes were built from Illumina paired reads assembled de novo. Supporting datasets of raw reads, assessments, and sequences from co-enriched heterotrophic marine bacteria are also provided. These three genomes represent members of the low light-adapted LLIV Prochlorococcus clade that are closely related, with 99.9% average nucleotide identity between pairs, yet vary in gene content. Expanding the powerful toolkit of Prochlorococcus genomes, these sequences provide an opportunity to study fine-scale variation and microevolutionary processes.

Abstract

Abstract Pulmonary vascular resistance (PVR) is a marker of pulmonary vascular remodeling. A non-invasive model assessed by cardiovascular magnetic resonance (CMR) has been proposed to estimate PVR. However, its accuracy has not yet been evaluated in patients with heart failure. We prospectively included 108 patients admitted with acute heart failure (AHF), in whom a right heart catheterization (RHC) and CMR were performed at the same day. PVR was estimated by CMR applying the model: PVR = 19.38 − [4.62 × Ln pulmonary artery average velocity (in cm/s)] − [0.08 × right ventricle ejection fraction (in %)], and by RHC using standard formulae. The median age of the cohort was 67 years (interquartile range 58–73), and 34% were females. The median of PVR assessed by RHC and CMR were 2.2 WU (1.5–4) and 5 WU (3.4–7), respectively. We found a weak correlation between invasive PVR and PVR assessed by CMR (Spearman r = 0.21, p = 0.02). The area under the ROC curve for PVR assessed by CMR to detect PVR ≥ 3 WU was 0.57, 95% confidence interval (CI): 0.47–0.68. In patients with AHF, the non-invasive estimation of PVR using CMR shows poor accuracy, as well as a limited capacity to discriminate increased PVR values.

Abstract

Despite the positive response of Colombia’s health system to the arrival of Venezuelan migrants, the new challenges that accompany the COVID-19 pandemic have triggered a closed-borders response that runs the risk of encouraging a negative view of migrants and increasing their health risks. This manuscript discusses the recommendations that could be proposed in the case of a country with limited resources such as Colombia to respond to the needs of the Venezuelan mixed migrant flows.

Abstract

Los desafíos de la migración a la salud pública en Iberoamérica en tiempos de la COVID-19 muestra la importancia de establecer estrategias que se enfoquen en los problemas que enfrentan los migrantes para acudir a los servicios de salud en otros países y para afrontar situaciones de precariedad. Además, evidencia la debilidad de aquellos Estados que no logran implementar estrategias que garanticen el cumplimiento de los derechos básicos de los migrantes, analiza cómo ellos vivieron la pandemia de la COVID-19 y muestra posibles soluciones políticas que podrían mejorar su bienestar y su salud. A través de un enfoque interseccional, este libro evidencia una problemática creciente de exclusión social en el sector de la salud, el cual debe dar una respuesta apropiada a sus poblaciones y, al mismo tiempo, enfrentar una nueva realidad migratoria.

Abstract

Los sistemas espaciales se caracterizan por la planeación y creación de todos sus segmentos con el fin de que en conjunto se cumpla una misión; con relación a estos sistemas, en Colombia han sido desarrollados dos misiones espaciales: el Libertad 1, un CubeSat DE 1U de la Universidad Sergio Arboleda y el FACSAT1, un CubeSat de 3U de la Fuerza Aérea Colombiana. Dichas misiones generaron el desarrollo completo del segmento espacial denominado satélite, a su vez han generado el segmento terrestre denominado Estación terrena. Para el asegurar el éxito del cumplimiento de la misión se hace necesario tener control sobre el desarrollo del segmento terrestre; es decir, las estaciones terrenas, por esta razón, y con la motivación de la construcción del segmento terrestre de una misión espacial en la Fundación Universitaria Los Libertadores, se logró definir un diseño preliminar para rastrear satélites del tipo pico y nano dentro del segmento radioaficionado o universitario. Con base en la investigación aplicada se buscó la generación de conocimiento dentro de la institución con la aplicación en el sector espacial, desarrollando las pautas necesarias que permitieran la identificación de los diferentes componentes para la construcción de una Estación Terrena para pequeños satélites. Con la búsqueda de las capacidades necesarias para obtener una recepción adecuada de los satélites, se obtuvo una estación terrena de bajo costo usando tecnología comercial y, principalmente, componentes de hardware del tipo SDR. Finalmente, se realizó una comparación con estaciones terrenas bajo costo para mirar la contribución en Colombia.

Abstract

Resumen Introducción: La Meningitis Bacteriana Aguda (MBA) corresponde a la inflamación de las leptomeninges por presencia de bacterias piógenas. La epidemiología es variable y depende multifactorial. A pesar de los avances en medicina la mortalidad de la MBA se ha mantenido estable, evidenciando la necesidad de estudiar esta patología para orientar estrategias de prevención y tratamiento. Objetivos: Determinar la prevalencia de los agentes etiológicos de MBA confirmadas en adultos en el Hospital San Martín de Quillota (HSMQ) entre los años 2012 y 2018. Establecer la tasa de resistencia a antibióticos. Determinar el perfil de los pacientes, y establecer la relación entre perfil, agente etiológico identificado y desenlace. Métodos: c muestra de 38 casos, se estableció la prevalencia de los patógenos involucrados y se realizó un análisis estadístico considerando los factores de riesgo, sus días de estadía y su condición al egreso hospitalario. Resultados: 15 casos en que no se aisló patógeno en LCR (líquido cefalorraquídeo), 13 MBA por neumococo, 4 por Haemophilus spp, 3 por meningococo, 2 por Staphylococcus spp y 1 por Mycobacterium tuberculosis. En el grupo sin agente aislado se observó un mejor pronóstico, valores de PCR (proteína C reactiva) en sangre menores y valores de glucorraquia mayores. Se registraron 6 fallecimientos por MBA. Conclusión: La prevalencia de los agentes etiológicos fue similar a la descrita en la literatura, con neumococo como el microorganismo más frecuente, no se reportaron casos de Listeria monocytogenes. Probablemente en el grupo sin agente aislado se incluyeron casos de meningitis virales.

Abstract

BACKGROUND There were gaps between guidelines and practice when surgery was the only treatment for aortic stenosis (AS). OBJECTIVES This study analyzed the decision to intervene in patients with severe AS in the EORP VHD (EURObservational Research Programme Valvular Heart Disease) II survey. METHODS Among 2,152 patients with severe AS, 1,271 patients with high-gradient AS who were symptomatic fulfilled a Class I recommendation for intervention according to the 2012 European Society of Cardiology guidelines; the primary end point was the decision for intervention. RESULTS A decision not to intervene was taken in 262 patients (20.6%). In multivariate analysis, the decision not to intervene was associated with older age (odds ratio [OR]: 1.34 per 10-year increase; 95% CI: 1.11 to 1.61; P = 0.002), New York Heart Association functional classes I and II versus III (OR: 1.63; 95% CI: 1.16 to 2.30; P = 0.005), higher age adjusted Charlson comorbidity index (OR: 1.09 per 1-point increase; 95% CI: 1.01 to 1.17; P = 0.03), and a lower transaortic mean gradient (OR: 0.81 per 10-mm Hg decrease; 95% CI: 0.71 to 0.92; P < 0.001). During the study period, 346 patients (40.2%, median age 84 years, median EuroSCORE II [European System for Cardiac Operative Risk Evaluation II] 3.1%) underwent transcatheter intervention and 515 (59.8%, median age 69 years, median EuroSCORE II 1.5%) underwent surgery. A decision not to intervene versus intervention was associated with lower 6-month survival (87.4%; 95% CI: 82.0 to 91.3 vs 94.6%; 95% CI: 92.8 to 95.9; P < 0.001). CONCLUSIONS A decision not to intervene was taken in 1 in 5 patients with severe symptomatic AS despite a Class I recommendation for intervention and the decision was particularly associated with older age and combined comorbidities. Transcatheter intervention was extensively used in octogenarians. (J Am Coll Cardiol 2021;78:2131-2143) (c) 2021 by the American College of Cardiology Foundation.

Abstract

The psychosomatic concept in the Latin American region is immersed in the mental health concept. This is part of the generic notion of public health and therefore involves the pragmatic application of knowledge in various fields: clinical, epidemiological, neurobiological, sociocultural, and basic research, as the most important ones. Concepts and policies regarding mental health have evolved over the last decades and are now well established in several countries of the region.

Abstract

IntroductionComplete revascularization (CR) in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD), is associated with a reduction in major adverse cardiovascular events (MACE). However, there is uncertainty about whether nonculprit-lesion revascularization should be performed, during index hospitalization or delayed, especially regarding health care resources utilization. In this study, we aimed to evaluate the impact of in-hospital nonculprit-lesion revascularization vs. delayed (after discharge) revascularization on the length of index hospitalization.MethodsIn this single-center study, we randomly assigned patients with STEMI and MVD who underwent successful culprit-lesion PCI to a strategy of either CR during in-hospital admission or a delayed CR after discharge. The first primary endpoint was the length of hospital stay. The second endpoint was the composite of cardiovascular death, myocardial infarction or ischemia-driven revascularization at 12 months (MACE).ResultsFrom January 2018 to December 2022, we enrolled 258 patients (131 allocated to CR during in-hospital admission and 127 to an after-discharge CR). We found a significant reduction in the length of hospital stay in those assigned to after-discharge CR strategy [4 days (3-5) versus 7 days (5-9); p = 0.001]. At 12-month of follow-up, no differences were found in the occurrence of MACE, 7 (5.34%) patients in in-hospital CR and 4 (3.15%) in after-discharge CR strategy; (hazard ratio, 0.59; 95% confidence interval, 0.17 to 2.02; p = 0.397).ConclusionsIn STEMI patients with MVD, an after-discharge CR strategy reduces the length of index hospitalization without an increased risk of MACE after 12 months of follow-up.Trial registrationClinicalTrials.gov number: NCT04743154.

Abstract

: Objectives The purpose of this study was to develop the nitrate reductase assay (NRA) for the rapid detection of pyrazinamide resistance in Mycobacterium tuberculosis using nicotinamide resistance as a marker of pyrazinamide resistance in Löwenstein–Jensen (LJ) medium at neutral pH. : Methods We tested 68 M. tuberculosis isolates using nicotinamide at three different concentrations (1000, 500 and 250 mg/L) by the NRA in LJ medium and compared the results with those obtained with the BACTEC 460-TB or the BACTEC MGIT 960 as reference standard methods. Mutations in the pncA gene were detected by DNA sequencing of the pyrazinamide-resistant isolates. : Results Out of 34 M. tuberculosis pyrazinamide-resistant isolates, 31 were found to be resistant to 1000 and 500 mg/L nicotinamide giving sensitivity and specificity of 91% and 94%, respectively. At 250 mg/L nicotinamide, the sensitivity and specificity decreased to 91% and 71%, respectively. Results were obtained in an average of 10 days. Based on these results, a tentative breakpoint concentration of 500 mg/L nicotinamide was defined. DNA sequencing of the pncA gene detected mutations in 26 out of 34 M. tuberculosis isolates resistant to pyrazinamide. : Conclusions The NRA using nicotinamide to detect resistance to pyrazinamide in LJ medium is a rapid and accurate method that could be useful in limited-resource countries where the BACTEC 460-TB or the BACTEC MGIT 960 system is not available.

Abstract

Los sistemas espaciales se caracterizan por la planeación y creación de todos sus segmentos con el fin de que en conjunto se cumpla una misión; con relación a estos sistemas, en Colombia han sido desarrollados dos misiones espaciales: el Libertad 1, un CubeSat DE 1U de la Universidad Sergio Arboleda y el FACSAT1, un CubeSat de 3U de la Fuerza Aérea Colombiana. Dichas misiones generaron el desarrollo completo del segmento espacial denominado satélite, a su vez han generado el segmento terrestre denominado Estación terrena. Para el asegurar el éxito del cumplimiento de la misión se hace necesario tener control sobre el desarrollo del segmento terrestre; es decir, las estaciones terrenas, por esta razón, y con la motivación de la construcción del segmento terrestre de una misión espacial en la Fundación Universitaria Los Libertadores, se logró definir un diseño preliminar para rastrear satélites del tipo pico y nano dentro del segmento radioaficionado o universitario. Con base en la investigación aplicada se buscó la generación de conocimiento dentro de la institución con la aplicación en el sector espacial, desarrollando las pautas necesarias que permitieran la identificación de los diferentes componentes para la construcción de una Estación Terrena para pequeños satélites. Con la búsqueda de las capacidades necesarias para obtener una recepción adecuada de los satélites, se obtuvo una estación terrena de bajo costo usando tecnología comercial y, principalmente, componentes de hardware del tipo SDR. Finalmente, se realizó una comparación con estaciones terrenas bajo costo para mirar la contribución en Colombia.
