Acute right ventricular failure in COVID-19 infection: A case series.

Severe forms of COVID-19 infection are associated with the need for invasive mechanical ventilation and thromboembolic complications; those can affect the cardiac function especially the right ventricle performance. Critical care echocardiography has rapidly evolved as the election technique in the evaluation of the critically ill patients. This technique has the advantage that it can be done at patient´s bedside and helps to provide the appropriate treatment and to monitoring maneuver's response.

[Circulatory support with venoarterial ECMO in a patient with biventricular Takotsubo cardiomyopathy].

La cardiomiopatía de Takotsubo es una entidad caracterizada por disfunción ventricular aguda y transitoria, la cual está generalmente relacionada a un evento desencadenante (estrés emocional o físico) y que, por lo general, se presenta con disfunción sistólica regional del ventrículo izquierdo, aunque hasta en un 30% puede ser biventricular. Según su severidad, en algunos casos puede condicionar choque cardiogénico refractario a manejo con inotrópicos y vasopresores, por lo que para estos casos deben considerarse los dispositivos de asistencia circulatoria. Presentamos el caso de una paciente joven a quien se realizó cambio valvular pulmonar con prótesis biológica, la cual siete semanas posteriores a la cirugía acudió al servicio de urgencias con derrame pericárdico y fisiología de tamponade secundario a síndrome pospericardiotomía.

Transthoracic echocardiography during prone position ventilation: Lessons from the COVID-19 pandemic.

Objective: The current coronavirus disease 2019 (COVID-19 outbreak) demands an increased need for hospitalizations in emergency departments (EDs) and critical care units. Owing to refractory hypoxemia, prone position ventilation has been used more frequently and patients will need repeated hemodynamic assessments. Our main objective was to show the feasibility of obtaining images to measure multiple parameters with transthoracic echocardiography during the prone position ventilation.

Feasibility in the echocardiographic estimation of parameters of the right ventricle in prone position.

Background: Echocardiographic cardiac parameters in the prone position are usually obtained with an esophageal probe. The feasibility of obtaining them by means of a transthoracic approach is unknown.

Objective: Estimating the feasibility to obtain parameters of the right ventricle by transthoracic echocardiography in prone position on the subject.

Critical care ultrasonography during COVID-19 pandemic: The ORACLE protocol.

Background: Coronavirus disease 2019 (COVID-19) is characterized by severe lung involvement and hemodynamic alterations. Critical care ultrasonography is vital because it provides real time information for diagnosis and treatment. Suggested protocols for image acquisition and measurements have not yet been evaluated.

Ibero⁻American Consensus on Low- and No-Calorie Sweeteners: Safety, Nutritional Aspects and Benefits in Food and Beverages.

International scientific experts in food, nutrition, dietetics, endocrinology, physical activity, paediatrics, nursing, toxicology and public health met in Lisbon on 2⁻4 July 2017 to develop a Consensus on the use of low- and no-calorie sweeteners (LNCS) as substitutes for sugars and other caloric sweeteners. LNCS are food additives that are broadly used as sugar substitutes to sweeten foods and beverages with the addition of fewer or no calories. They are also used in medicines, health-care products, such as toothpaste, and food supplements.

Venous thromboembolism in heart transplant recipients: incidence, recurrence and predisposing factors.

Background: A high frequency of venous thromboembolism (VTE) has been observed after lung, kidney, and liver transplantation. However, data about the incidence of this complication among heart transplant (HT) recipients are lacking.

Methods: We analyzed the incidence, recurrence, and predisposing factors of VTE in a single-center cohort of 635 patients who underwent HT from April 1991 to April 2013.
