ABSTRACT
This editorial discusses the emergence of visual abstracts within journals to disseminate findings. Published alongside Aggarwal's retrospective study reporting that visual abstracts do not increase impact scores more than conventional abstracts of clinical research, it is suggested that visual abstracts may have a greater impact for smaller, specialty journals.

We report the case of a patient who was initially presented with ischemic priapism to the emergency department. He was treated with adrenaline intracavernous injections and aspiration with irrigation of the corpora cavernosa and distal shunt. In the postoperative period, anemia, basophilia, eosinophilia, thrombocytosis and hyperleukocytosis were detected. The patient was subsequently diagnosed with chronic myeloid leukemia. Priapism is a rare manifestation of chronic myeloid leukemia (≤ 3%) and occurs mostly due to hyperleukocytosis, resulting in thrombus formation and corporal venous outflow obstruction. Priapism occurring in any setting is considered as a medical emergency that requires immediate local therapy because of resulting irreversible cell damage and fibrosis if not treated within the first 24-48 h.

Abstract Recent studies have reported the occurrence of thrombotic phenomena or coagulopathy in patients with COVID-19. There are divergent positions regarding the prevention, diagnosis, and treatment of these phenomena, and current clinical practice is based solely on deductions by extension from retrospective studies, case series, observational studies, and international guidelines developed prior to the pandemic. In this context, the aim was to generate a group of recommendations on the prevention, diagnosis and management of thrombotic complications associated with COVID-19. Methods: A rapid guidance was carried out applying the GRADE Evidence to Decision (EtD) frameworks and an iterative participation system, with statistical and qualitative analysis. Results: 31 clinical recommendations were generated focused on: a) Coagulation tests in symptomatic adults with suspected infection or confirmed SARS CoV-2 infection; b) Thromboprophylaxis in adults diagnosed with COVID-19 (Risk scales, thromboprophylaxis for outpatient, in-hospital management, and duration of thromboprophylaxis after discharge from hospitalization), c) Diagnosis and treatment of thrombotic complications, and d) Management of people with previous indication of anticoagulant agents. Conclusions: Recommendations of this consensus guide clinical decision-making regarding the prevention, diagnosis, and treatment of thrombotic phenomena in patients with COVID-19, and represent an agreement that will help decrease the dispersion in clinical practices according to the challenge imposed by the pandemic.

Introducción estudios recientes han reportado fenómenos trombóticos o coagulopatía en pacientes con COVID-19. Hay posiciones divergentes en cuanto a la prevención, el diagnóstico y el tratamiento de estos fenómenos, y la práctica clínica actual está basada únicamente en deducciones por extensión a partir de estudios retrospectivos, series de casos, estudios observacionales y guías internacionales desarrolladas previas a la pandemia. Objetivo establecer una serie de recomendaciones sobre prevención, diagnóstico y manejo de las complicaciones trombóticas asociadas a COVID-19. Métodos se desarrolló una guía rápida en la que se aplicó el marco de la evidencia a la decisión (EtD) de GRADE y un sistema de participación iterativo, con análisis estadísticos y cualitativos de sus resultados. Resultados se generaron 31 recomendaciones clínicas enfocadas a: a) Pruebas de coagulación en adultos sintomáticos con sospecha de infección o infección confirmada por SARS-CoV-2; b) Tromboprofilaxis en personas adultas con diagnóstico de COVID-19 (escalas de riesgo, tromboprofilaxis de manejo ambulatorio, intrahospitalario y duración de tromboprofilaxis después del egreso de hospitalización), c) Diagnóstico y tratamiento de las complicaciones trombóticas y d) Manejo de personas con indicación previa a usar agentes anticoagulantes. Conclusiones las recomendaciones clínicas de este consenso orientan la toma de decisiones clínicas respecto a prevención, diagnóstico y tratamiento de fenómenos trombóticos en pacientes con COVID-19, y representan un acuerdo que ayudará a disminuir la dispersión en las prácticas clínicas acorde con el desafío que impone la pandemia.

Increasing thermogenesis in white adipose tissues can be used to treat individuals at high risk for obesity and cardiovascular disease. The objective of this study was to determine the function of EP300-interacting inhibitor of differentiation (EID1), an inhibitor of muscle differentiation, in the induction of beige adipocytes from adipose mesenchymal stem cells (ADMSCs). Subcutaneous adipose tissue was obtained from healthy women undergoing abdominoplasty. ADMSCs were isolated in vitro, grown, and transfected with EID1 or EID1 siRNA, and differentiation was induced after 48âh by administering rosiglitazone. The effects of EID1 expression under the control of the aP2 promoter (aP2-EID1) were also evaluated in mature adipocytes that were differentiated from ADMSCs. Transfection of EID1 into ADMSCs reduced triglyceride accumulation while increasing levels of thermogenic proteins, such as PGC1α, TFAM, and mitochondrial uncoupling protein 1 (UCP1), all of which are markers of energy expenditure and mitochondrial activity. Furthermore, increased expression of the beige phenotype markers CITED1 and CD137 was observed. Transfection of aP2-EID1 transfection induced the conversion of mature white adipocytes to beige adipocytes, as evidenced by increased expression of PGC1α, UCP1, TFAM, and CITED1. These results indicate that EID1 can modulate ADMSCs, inducing a brown/beige lineage. EID1 may also activate beiging in white adipocytes obtained from subcutaneous human adipose tissue.

We present a case of a previously healthy 30-year-old man who presented with a necrotising pneumonia and bronchiectasis. His infectious workup revealed a Staphylococcus aureus pneumonia. Since bronchiectasis and necrotising pneumonia are unusual findings in an otherwise healthy person, further investigation was pursued. His workup revealed non-classic cystic fibrosis (CF) and allergic bronchopulmonary aspergillosis (ABPA). This case discusses the differential diagnosis of bronchiectasis, the diagnosis and treatment of ABPA, and the role of CF mutations in the pathogenesis of ABPA.

The cerebral cortex communicates with the cerebellum via polysynaptic circuits. Separate regions of the cerebellum are connected to distinct cerebral areas, forming a complex topography. In this study we explored the organization of cerebrocerebellar circuits in the human using resting-state functional connectivity MRI (fcMRI). Data from 1,000 subjects were registered using nonlinear deformation of the cerebellum in combination with surface-based alignment of the cerebral cortex. The foot, hand, and tongue representations were localized in subjects performing movements. fcMRI maps derived from seed regions placed in different parts of the motor body representation yielded the expected inverted map of somatomotor topography in the anterior lobe and the upright map in the posterior lobe. Next, we mapped the complete topography of the cerebellum by estimating the principal cerebral target for each point in the cerebellum in a discovery sample of 500 subjects and replicated the topography in 500 independent subjects. The majority of the human cerebellum maps to association areas. Quantitative analysis of 17 distinct cerebral networks revealed that the extent of the cerebellum dedicated to each network is proportional to the network's extent in the cerebrum with a few exceptions, including primary visual cortex, which is not represented in the cerebellum. Like somatomotor representations, cerebellar regions linked to association cortex have separate anterior and posterior representations that are oriented as mirror images of one another. The orderly topography of the representations suggests that the cerebellum possesses at least two large, homotopic maps of the full cerebrum and possibly a smaller third map.

Conclusiones: el Hospital de San José tiene gran experiencia en la realización de procedimientos quirúrgicos programados en pacientes con hemoflia A y B y enfermedad de von Willebrand, los cuales a lo largo de estos 16 años han sido realizados con éxito y baja tasa de complicaciones.
To describe haemostatic management of patients with hemophilia and von Willebrand disease before, during and after surgery. Materials and Methods: case series of patients diagnosed with hemophilia A, B, von Willebrand disease and factor VII defciency, from January 1993 to June 2009 at Hospital de San José, Bogotá DC. Results: 35 scheduled surgeries of various specialties in 28 patients (4 females, 24 males). For those with hemophilia A and B the objective in terms of level of haemostasis in orthopedic procedures was: on day one 100%, from day two to fve: 74% and day 6 and so on: 60%; in dental procedures, on day one the factor was corrected an average of 85% and from day two to fve: 65%. Patients with Von Willebrand disease were managed with a 50 IU/k dose every 8 to 24 hours. There were 3 cases of infection and no deaths occurred. Conclusions: Hospital de San José has gained a vast experience in conducting scheduled surgical procedures in patients with hemophilia A, B and von Willebrand disease. These patients have been managed successfully during these 16 years with a low complication rate.

La anemia hemolítica autoinmune se asocia con una variedad de virus hepatotrópicos, en particular citomegalovirus (CMV), virus del Epstein-Barr y de la hepatitis B. No es frecuente dentro de la historia natural de la hepatitis A, la aparición de anemia hemolítica, y cuando se presenta, generalmente se asocia a deficiencia de glucosa-6-fosfato deshidrogenasa. Presentamos el caso de un paciente de sexo masculino sin hemólisis previa, con astenia e ictericia de dos meses de evolución y hepatomegalia 14 cm por debajo del reborde costal derecho. Los hallazgos en los exámenes de laboratorios mostraron anemia hemolítica con Coombs directo positivo, anticuerpos tipo inmunoglobulina M contra el virus de la hepatitis A positivos, niveles de bilirrubinas 20 veces y aminotrasferasas cuatro veces por arriba del rango normal; con estos datos el paciente fue diagnosticado como hepatitis A complicada con anemia hemolítica y probable hepatitis autoinmune asociada, por lo que se inició manejo con corticoides, alcanzándose mejoría clínica. Resaltamos la importancia de descartar la infección por el virus de la hepatitis A como posible etiología de anemia hemolítica autoinmune.
