Acute kidney injury (AKI) is a significant problem for patients admitted to the intensive care unit (ICU), both due to the high incidence and associated mortality with rates of AKI requiring renal replacement therapy (RRT) of over 5%, and mortality rates with AKI of over 60% [1,2]. Ultrasound can be used to identify those at risk for AKI and assist with AKI management. Risk factors for AKI in the ICU not only include hypoperfusion but also venous congestion and volume overload. Volume overload and vascular congestion are associated with multi-organ dysfunction and worse renal outcomes. Daily and overall fluid balance, daily weights, and physical examination for edema can be inaccurate and belie true systemic venous pressure [3-5]. Bedside ultrasound allows providers to evaluate vascular flow patterns and obtain a more reliable evaluation of volume status to guide and individualize therapies. Cardiac, lung, and vascular patterns on ultrasound can identify preload responsiveness, which should be assessed to safely manage ongoing fluid resuscitation and assess for signs of fluid intolerance. Here we present an overview in the use of point of care ultrasound with particular emphasis on nephro-centric strategies, namely in the identification of the type of renal injury, renal vascular flow assessment, the static measure of volume status, as well as dynamic evaluation for volume optimization in critically ill patients.

Objectives:. Coronavirus disease 2019 is associated with high mortality rates and multiple organ damage. There is increasing evidence that these patients are at risk for various cardiovascular insults; however, there are currently no guidelines for the diagnosis and management of such cardiovascular complications in patients with coronavirus disease 2019. We share data and recommendations from a multidisciplinary team to highlight our institution’s clinical experiences and guidelines for managing cardiovascular complications of coronavirus disease 2019. Design, Setting, and Patients:. This was a retrospective cohort study of patients admitted to one of six ICUs dedicated to the care of patients with coronavirus disease 2019 located in three hospitals within one academic medical center in Atlanta, Georgia. Measurements/Interventions:. Chart review was conducted for sociodemographic, laboratory, and clinical data. Rates of specific cardiovascular complications were assessed, and data were analyzed using a chi-square or Wilcoxon rank-sum test for categorical and continuous variables. Additionally, certain cases are presented to demonstrate the sub committee’s recommendations. Main Results:. Two-hundred eighty-eight patients were admitted to the ICU with coronavirus disease 2019. Of these, 86 died (29.9%), 242 (84.03%) had troponin elevation, 70 (24.31%) had dysrhythmias, four (1.39%) had ST-elevation myocardial infarction, eight (2.78%) developed cor pulmonale, and 190 (65.97%) with shock. There was increased mortality risk in patients with greater degrees of troponin elevation (p < 0.001) and with the development of arrhythmias (p < 0.001), cor pulmonale (p < 0.001), and shock (p < 0.001). Conclusions:. While there are guidelines for the diagnosis and management of pulmonary complications of coronavirus disease 2019, there needs to be more information regarding the management of cardiovascular complications as well. These recommendations garnered from the coronavirus disease 2019 cardiology subcommittee from our institution will add to the existing knowledge of these potential cardiovascular insults as well as highlight suggestions for the diagnosis and management of the range of cardiovascular complications of coronavirus disease 2019. Additionally, with the spread of coronavirus disease 2019, our case-based recommendations provide a bedside resource for providers newly caring for patients with coronavirus disease 2019.

INTRODUCCIÓN: La práctica de la neurología como especialidad clínica es relativamente reciente en Colombia, a pesar de que esta área ha mostrado progresos académicos significativos; la información sociodemográfica es limitada. OBJETIVO: Describir las características sociodemográficas de los neurólogos laboralmente activos en Colombia. METODOLOGÍA: Estudio descriptivo en dos periodos. La información se obtuvo mediante encuestas autodiligenciadas a los asistentes al Congreso Nacional de Neurología del año 2016; la del 2020 se recolectó empleando cuestionarios en línea a través de formularios Google. RESULTADOS: Se contabilizaron 549 neurólogos laboralmente activos en el territorio colombiano. El análisis de las muestras 2016 y 2020 mostró que la mayor proporción de estos especialistas se concentraba en Bogotá (45,4 %), Medellín (13,4 %) y Cali (8,4 %), con una ocupación escasa en ciudades no capitales. La comparación de horas laborales e ingresos económicos al analizar 2016 y 2020 no mostró diferencias. El mayor tiempo de ejercicio se correlacionó con mayores ingresos, tanto en el 2016 (p < 0,001) como en el 2020 (p < 0,01). CONCLUSIONES: Excepto por el incremento en la población de nuevos neurólogos, las características socio-demográficas de los neurólogos en Colombia se mantienen sin variaciones al comparar los años 2016 y 2020.
