Valoración nutricional por ecografía del recto femoral y el tejido adiposo preperitoneal como predictores del riesgo de complicaciones del paciente hospitalizado / Nutritional assessment by ultrasound of the rectus femoris and preperitoneal adipose tissue as predictors of hospitalized patient complications

Introducción La desnutrición y la sarcopenia se asocian al aumento del riesgo de eventos adversos y peor evolución en los pacientes hospitalizados. La ecografía constituye una herramienta de utilidad en la evaluación de la composición corporal. Pacientes y métodos Se reclutaron 23 pacientes ingresados en una planta de hospitalización. Se recogieron las variables ecográficas del tejido muscular y tejido adiposo, así como su variación durante el ingreso. Correlacionándose con datos antropométricos, clínicos y analíticos. Resultados Observamos una correlación de las mediciones ecográficas con la duración de la hospitalización (grasa preperitoneal máxima: −0,585, grosor del recto femoral [RF]: −0,539, área del RF: −0,540), la fragilidad (RF: −0,599) y la dependencia (RF: 0,628). La capacidad de contracción del RF se correlacionó con el ejercicio semanal reportado (0,642). Conclusión El grosor del RF y de la grasa preperitoneal se correlacionan con el número de días de ingreso y la capacidad funcional, erigiéndose como variables pronósticas (AU)

Introduction Malnutrition and sarcopenia are associated with increased risk of adverse events and worse outcome in hospitalised patients. Ultrasonography is a useful tool in the assessment of body composition. Patients and methods Twenty-three patients admitted to a hospital ward were recruited. Ultrasonographic variables of muscle tissue and adipose tissue were collected, as well as their variation during admission. These were correlated with anthropometric, clinical and analytical data. Results We observed a correlation of ultrasound measurements with length of hospitalisation (maximum preperitoneal fat −0.585, rectus femoris thickness [RF] −0.539, RF area −0.540), frailty (RF −0.599) and dependency (RF 0.628). RF contractile capacity correlated with reported weekly exercise (0.642). Conclusion RF and preperitoneal fat thickness correlate with the number of days of admission and functional capacity, emerging as prognostic variables (AU)

Principales aplicaciones de la ecografía clínica en cuidados paliativos / Main applications of clinical ultrasound in palliative care

Las personas con enfermedades oncológicas avanzadas padecen procesos clínicos intercurrentes y otras manifestaciones relacionadas con la propia progresión tumoral que generan un gran impacto en su calidad de vida. Los profesionales que trabajan en este campo necesitan incorporar nuevos conocimientos y herramientas de diagnóstico y tratamiento que faciliten el manejo de estas personas, de complejidad tan elevada, de la forma menos invasiva posible1. La ecografía clínica (EC) es una de esas herramientas cuyo desarrollo ha sido excepcional en las últimas décadas. Los avances tecnológicos han permitido disponer de equipos de bolsillo cada vez más sofisticados, asequibles económicamente y que pueden ser utilizados allí donde se encuentre la persona enferma como una extensión de la exploración física2. De esta manera el profesional puede dar respuesta a diferentes situaciones o entidades sindrómicas en las que la rentabilidad de la EC puede ser elevada. La pretensión es evitar, en la medida de lo posible, el traslado del paciente al hospital o a una ubicación intrahospitalaria, lo que redunda en su confort y calidad de vida, además de empoderar al profesional en la toma de decisiones clínicas. (AU)

People with advanced cancer suffer from intercurrent clinical conditions and other tumor progression-related manifestations that can have a great impact on their quality of life. Professionals working in this field need to incorporate new knowledge, as well as diagnostic and treatment tools to facilitate the management of these highly complex patients in the least invasive way possible1. Clinical ultrasound (CU) is one of those tools whose development has been exceptional in recent decades. Technological advances have made it possible to have increasingly sophisticated and affordable pocket equipments available, which can be used wherever the patient is as an extension of physical examination2. In this way, a professional can respond to different situations or syndromic conditions in which CU yield may be high. The aim is to avoid, whenever possible, the transfer of patients to in-hospital facilities, which can result in loss of both comfort and quality of life. In addition, an appropriate use of CU can empower the team charged with making clinical decisions. (AU)

Papel del Doppler de la vena femoral en pacientes con insuficiencia cardiaca aguda: resultados de un estudio multicéntrico prospectivo / Role of the femoral vein doppler in acute heart failure patients: results from a prospective multicentric study

Antecedentes y objetivo El objetivo de nuestro estudio es definir el papel de la ecografía Doppler pulsada (PW-Doppler) de la vena femoral común en la evaluación de la dilatación de la vena cava inferior (VCI), la probabilidad de hipertensión pulmonar, la insuficiencia tricuspídea y la excursión sistólica del plano anular tricuspídeo (TAPSE). Métodos Se trata de un estudio prospectivo en dos hospitales en 74 pacientes ingresados con insuficiencia cardiaca aguda. Se realizó ecografía PW-Doppler de vena femoral común, ecocardiografía y evaluación de la VCI en el momento del ingreso, así como PW-Doppler y ecografía de VCI al alta hospitalaria. Resultados La detección de un flujo pulsátil (138 exploraciones) tuvo una curva ROC excelente para la detección de VCI mayor de 2cm (AUC 0,931, Sn95%, Sp 90%, VPP 93%, VPN 94%) con una odds ratio (OR) de 211,2 (intervalo de confianza del 95% 48,13-926,72). La pulsatilidad del flujo también tuvo el mayor rendimiento en la detección de la hipertensión pulmonar (AUC 0,8, Sn 95%, Sp 64%, VPP 84%, VPN 84%) y en la detección de la insuficiencia tricuspídea moderada-grave (AUC 0,79, Sn 95%, Sp 67%, VPP 88%, VPN 78%). Si el flujo es continuo, podemos descartar razonablemente una disminución del TAPSE (VPN 89%). Conclusión La detección del flujo PW-Doppler de vena femoral común puede ser una ventana alternativa para la detección de una dilatación de la VCI de 2cm, TR significativa y la probabilidad de hipertensión pulmonar elevada en la insuficiencia cardiaca aguda. También permite descartar razonablemente la disfunción del ventrículo derecho en casos de normalidad en estos pacientes (AU)

Background and objective The aim of our study is to define the role of Pulsed-Doppler (PW-Doppler) Ultrasound of the common femoral vein in the assessment of dilatation Inferior Vena Cava (IVC), probability of Pulmonary Hypertension (PH), Tricuspid Regurgitation (TR), and Tricuspid annular plane systolic excursion (TAPSE). Methods This is a prospective two-hospital study in 74 patients admitted with acute heart failure (AHF). We performed PW-Doppler ultrasound of the common femoral vein, Point of Care cardiac ultrasonography and assessment of the IVC at the time of admission, as well as PW-Doppler and ultrasound of the IVC at hospital discharge. Results The detection of a pulsatile flow (138 scans) had an excellent ROC curve for the detection of IVC greater than 2cm (AUC 0.931, Sn 95%, Sp 90%, PPV 93%, NPV 94%) with an Odds Ratio (OR) of 211.2 (95% confidence interval 48.13-926.72). The pulsatility of the flow also had the highest performance in the detection of PH (AUC 0.8, Sn 95%, Sp 64%, PPV 84%, NPV 84%) and in the detection of moderate-severe TR (AUC 0.79, Sn 95%, Sp 67%, PPV 88%, NPV 78%). If the flow is continuous, we can reasonably rule out diminished TAPSE (NPV 89%). Conclussion Detection of PW-Doppler flow of the common femoral vein may be an alternative window for the detection of an IVC dilation of 2cm, significant TR, and the likelihood of high PH in acute heart failure. It also allows us to reasonably rule out dysfunction of the right ventricle in cases of normality in these patients (AU)

Principales aplicaciones de la ecografía clínica en cuidados paliativos / Main applications of point-of care ultrasound in palliative care

El uso de la ecografía clínica, entendida como una extensión de la exploración física que ayuda a la toma de decisiones clínicas en tiempo real, se ha generalizado en diversas especialidades médicas y quirúrgicas. En los últimos años, los avances tecnológicos han permitido disponer de ecógrafos de bolsillo, económicamente asequibles, que pueden ser utilizados en el propio domicilio del paciente. En esta revisión se describen las principales aplicaciones de la ecografía clínica en cuidados paliativos, un escenario de potencial utilidad tanto para mejorar la certeza en el diagnóstico de procesos agudos intercurrentes, que producen un impacto en la calidad de vida del paciente, como para guiar la realización de procedimientos invasivos sin necesidad de desplazamientos al medio hospitalario. Para la implantación de la ecografía clínica en cuidados paliativos son necesarios programas formativos con objetivos concretos, definiendo curvas de aprendizaje y estableciendo alianzas con sociedades científicas de reconocida trayectoria docente, asistencial e investigadora para la acreditación de competencias (AU)

Combined with a physical examination, clinical ultrasound offers a valuable complement that can help guide clinical decision-making. In various medical and surgical specialties, it is increasingly used for diagnostic and therapeutic purposes. Due to recent technological advances, smaller and more affordable ultrasound machines are now being developed for use in home hospice care. The purpose of this paper is to describe how clinical ultrasound may be applied in Palliative Care, where it can be a valuable tool to assist the clinician in making better clinical decisions and to assist in accurately guiding palliative procedures. Furthermore, it can be used to identify unnecessary hospitalizations and prevent them from occurring. Training programs with specific objectives are necessary to implement clinical ultrasound in Palliative Care, as well as defining learning curves and promoting alliances with scientific societies that recognize the teaching, care and research trajectory for accreditation of competencies (AU)

Ecografía clínica en cuidados paliativos. Principios básicos / Clinical ultrasound in palliative care. Basic principles

La ecografía clínica se emplea cada vez por más profesionales sanitarios de diversas disciplinas asistenciales. En cuidados paliativos existen iniciativas que han puesto de manifiesto la utilidad de sus múltiples aplicaciones, permitiendo ofrecer respuestas a cuestiones diversas, tanto en el hospital como en el domicilio. No debe suponer una perturbación del confort del paciente contribuyendo a evitar la percepción por parte de pacientes y familiares de “abandono tecnológico” en las fases más avanzadas de la enfermedad. El avance tecnológico de estos dispositivos permite disponer de opciones que aúnan precio, portabilidad, sencillez de manejo y calidad de imagen suficiente para satisfacer los requisitos para su empleo en las necesidades asistenciales más habituales en cuidados paliativos. La curva de aprendizaje en su manejo es relativamente rápida, esperando que esta serie de publicaciones con material teórico-práctico en la revista Medicina Paliativa contribuyan a establecer una base de conocimiento para los profesionales interesados en este tema, pudiendo continuarse más adelante con un sistema para una adecuada acreditación de competencias. (AU)

Clinical ultrasound is being increasingly used by health professionals from various healthcare disciplines. In Palliative Care some initiatives have revealed the usefulness of its multiple applications, allowing to answer various questions both in the hospital and at home. It should not imply a disturbance of patient wellbeing, and helps avoid the perception, both by patients and relatives, of “technological abandonment” in the most advanced phases of disease. The technological advance of these devices allows having options that combine price, portability, ease of use, and sufficient image quality to satisfy the requirements of use in the most common care settings in Palliative Care. The learning curve in its operation is relatively fast, and we hope that this series of publications with theoretical-practical material in the Palliative Medicine journal will contribute to establishing a knowledge base for professionals interested in this topic, which might be later expanded by providing a system for adequate accreditation of competencies.

Role of the femoral vein doppler in acute heart failure patients: results from a prospective multicentric study.

BACKGROUND AND OBJECTIVE: The aim of our study is to define the role of Pulsed-Doppler (PW-Doppler) Ultrasound of the Common Femoral Vein (CFV) in the assessment of dilatation Inferior Vena Cava (IVC), probability of Pulmonary Hypertension (PH), Tricuspid Regurgitation (TR), and Tricuspid annular plane systolic excursion (TAPSE). METHODS: This is a prospective two-hospital study in 74 patients admitted with acute heart failure (AHF). We performed PW-Doppler ultrasound of the common femoral vein, Point of Care (POC) cardiac ultrasonography and assessment of the IVC at the time of admission, as well as PW-Doppler and ultrasound of the IVC at hospital discharge. RESULTS: The detection of a pulsatile flow (138 scans) had an excellent ROC curve for the detection of IVC greater than 2cm (AUC 0.931, Sn 95%, Sp 90%, PPV 93%, NPV 94%) with an Odds Ratio (OR) of 211.2 (95% confidence interval 48.13-926.72).

CONCLUSSION: Detection of PW-Doppler flow of the CFV may be an alternative window for the detection of an IVC dilation of 2cm, significant TR, and the likelihood of high PH in acute heart failure. It also allows us to reasonably rule out dysfunction of the right ventricle in cases of normality in these patients.

Ecografía multiórgano en infección por SARS-COV-2 / Multi-organ ultrasound for SARS-COV-2 disease

Aim: There is growing evidence regarding the imaging ultrasound findings of coronavirus disease 2019 COVID-19. Multi-organ ultrasoundhas played a significant role in the diagnosis and follow-up of thesepatients. The aim of this study was to describe the ultrasound findingsat pulmonary, cardiac and deep venous system of the lower extremities in patients with SARS-COV-2 infection.Material and method: Prospective, cross-sectional, observationalstudy was conducted in patients with confirmed COVID-19 who underwent a multi-organ point-of-care ultrasound (POCUS) examinationduring hospitalization.Results: A total of 107 patients were enrolled. Lung involvement waspresent in 100% of the patients, 93.4% bilaterally involvement. Themost affected lung area was the posteroinferior (94.39%) followed bythe lateral (89.72%). Subpleural consolidations were present in 71%of patients and consolidations larger than 1 cm in 25%. More echographic lung involvement is relational with the degree of respiratoryinsufficiency. Only two patients had proximal deep vein thrombosisin the lower extremities, 27 angiography tomography scan were performed and pulmonary thromboembolism was confirmed in 14 patients. The most frequent echocardiographic findings were impairedleft ventricular relaxation and left ventricular hypertrophy. All patientswith thromboembolic disease had severe or critical echocardiographicpulmonary involvement.Conclusions: Multi-organ POCUS ultrasound may be useful for themanifestations of COVID-19. The degree of lung ultrasound involvement was related to the degree of respiratory failure and to the presence of VTED. The relationship between DVT and PTE was lower thanexpected. Cardiac involvement has little relevance in our series. (AU)

Medición de la congestión venosa empleando la ecografía: protocolo VExUS / Measurement of venous congestion using ultrasound: the vexus protocol

Acute Heart Failure (AHF) is a clinical syndrome characterized by the appearance or worsening of cardinal symptoms derived from venous congestion,which carries a high morbidity and mortality burden. Unfortunately, in current clinical practice, common markers such as patient’s history, physicalexamination, and complementary tests are not sensitive enough for reliableassessment of volume status. In recent years, the use of Point-of-Care Ultrasound (POCUS) has been consolidated as a useful tool to detect the presenceand degree of venous congestion, providing a substantial improvement in thediagnosis and therapeutic management of these patients. In combination,pulmonary ultrasound, echocardiography and renal, suprahepatic and portalvenous flow patterns (VExUS protocol), we will be able better understand thevenous pathophysiology. This will allow us to identify the hemodynamic phenotype in patients with heart failure or to determine the target organ damagederived from heart failure (i.e., cardiorenal syndrome). All this would allowus to make an individualized adjustment of the treatment, as well as to serve as a prognostic marker of the evolution of the disease. (AU)

La Insuficiencia Cardíaca Aguda (ICA) es una entidad clínica caracterizadapor la aparición o empeoramiento de síntomatología cardinal derivada dela congestión venosa, relacionado con una alta morbi-mortalidad. En lapráctica clínica actual, los marcadores habituales como son la anamnesis,exploración física y pruebas complementarias, precisan del apoyo de otrastécnicas para valorar de forma fiable el estado congestivo de los pacientes.En los últimos años, se ha consolidado el uso de la Ecografía Point-of-Care(POCUS) como una herramienta útil para detectar la presencia y el grado decongestión venosa, aportando una mejora sustancial en el diagnóstico y enel manejo terapéutico de estos enfermos. Combinando la ecografía pulmonar, ecocardiografía y los patrones de flujo venoso renal, suprahepática yporta (protocolo VExUS), nos permite conocer mejor la fisiopatología de lacongestión venosay nos permitirá identificar el fenotipo hemodinámico enpacientes con insuficiencia cardíaca o determinar la lesión de órgano dianaderivada de la insuficiencia cardíaca. Todo ello nos puede permitir hacer unajuste individualizado del tratamiento, así como servir de marcador pronóstico de la evolución de la enfermedad. (AU)

Emerging applications of clinical ultrasonography.

In this work, we introduce the numerous emerging areas and frontiers in the use of point-of-care ultrasonography. Of these, we review the following three: 1) the use of clinical ultrasonography in infectious and tropical diseases (we address its usefulness in the diagnosis and follow-up of the main syndromes, in tropical diseases, and in areas with scarce resources); 2) the usefulness of clinical ultrasonography in the assessment of response to volume infusion in severely ill patients (we review basic concepts and the main static and dynamic variables used for this evaluation); and 3) the use of clinical ultrasonography in the assessment of muscle mass in elderly patients with primary sarcopenia (we review the main muscles and measurements used for it).

Point-of-care ultrasonography in the initial characterization of patients with COVID-19

Background: There is growing evidence regarding the imaging findings of coronavirus disease 2019 (COVID-19) in chest X-rays and computed tomography scans; however, their availability during this pandemic outbreak might be compromised. Currently, the role of point-of-care ultrasonography (POCUS) has yet to be explored.ObjectivesTo describe the POCUS findings of COVID-19 in patients with the disease admitted to the emergency department (ED), correlating them with vital signs, laboratory and radiologic results, therapeutic decisions, and the prognosis.MethodsProspective study performed in the ED of 2 academic hospitals. Patients with highly suspected or confirmed COVID-19 underwent a lung ultrasonography (lung POCUS), focused cardiac ultrasound (FOCUS), and inferior vena cava (IVC) exam.ResultsBetween March and April 2020, 96 patients were enrolled. The mean age was 68.2 years (SD 17.5). The most common findings in the lung POCUS were an irregular pleural line (63.2%), bilateral confluence (55.2%), and isolated B-lines (53.1%), which were associated with a positive RT-PCR (odds ratio 4.327; 95% CI 1.216–15.401; p<.001), and correlated with IL-6 levels (rho=0.622; p=.002). The IVC negatively correlated with levels of expiratory pO2 (rho=−0.539; p=.014) and inspiratory pO2 (rho=−0.527; p=0.017), and expiratory diameter positively correlated with troponin I (rho=0.509; p=.03). After the POCUS exam, almost 20% of the patients had an associated condition that required a change in their treatment or management.ConclusionsPOCUS parameters have the potential to impact the diagnosis, management, and prognosis of patients with confirmed or suspected COVID-19.

Clinical ultrasonography in the decision-making process in medicine point-of-care ultrasound in clinical decision making. / Ecografía clínica en el proceso de toma de decisiones en medicina.

Clinical ultrasonography has undergone significant development in recent years due to its considerable usefulness and equipment miniaturisation, which have enabled its use at the point of care. Clinical ultrasonography is a tool that supplements the classical anamnesis and physical examination, thereby increasing the practitioner's diagnostic power. This tool can be employed in numerous clinical scenarios and can be applied at all steps when making decisions about the patient. In the hands of the general practitioner, ultrasonography of the various areas of the body (multiorgan ultrasonography) optimises not only the diagnostic capacity but also the prognostic stratification and monitoring of progress after treatment has been applied. As with the systematic nature of conventional physical examinations, we need to establish an ultrasound examination protocol that supplements the physical examination, thereby redefining and boosting the classic examination.

Clinical ultrasonography in chronic obstructive pulmonary disease. / Ecografía clínica en la enfermedad pulmonar obstructiva crónica.

COPD is a highly prevalent disease and one of the most common reasons for hospitalization in Internal Medicine departments. COPD also has significant associated morbidity and mortality. In recent years, multiorgan clinical ultrasonography (pulmonary, cardiac and vascular) has emerged as a tool of considerable usefulness in managing patients with COPD in numerous situations, including the differential diagnosis of dyspnoea of uncertain origin, the assessment of the aetiology in episodes of exacerbation, detecting concomitant heart failure or associated pulmonary hypertension and as support in managing cardiovascular risk factors such as subclinical atherosclerosis. This study summarises the most important evidence regarding this approach and proposes future scenarios for the use of ultrasonography that will help improve the diagnosis, prognostic estimations and the selection of the optimal treatment for this type of patient.

Clinical ultrasonography in venous thromboembolism disease. / Ecografía clínica en la enfermedad tromboembólica venosa.

The use of clinical ultrasonography has grown exponentially in the past decade in various medical settings. As with other areas of activity in the field of internal medicine, clinical ultrasonography has been implemented in venous thromboembolism disease, both in deep vein thrombosis and pulmonary embolism. In this review, we cover the diagnostic techniques, both for deep vein thrombosis through compression ultrasonography and for multiorgan ultrasonography, which include compression ultrasonography, pulmonary ultrasonography in the search for pulmonary infarctions and echocardiography for detecting dilation and right ventricular dysfunction for the diagnosis of pulmonary embolism. We also establish the most common clinical scenarios in which clinical ultrasonography can be of assistance in actual clinical practice, as well as its limitations and current evidence.
