Assessing the impact of long-term inhaled corticosteroid therapy on patients with COVID-19 and coexisting chronic lung disease: A multicenter retrospective cohort study.

Background: Patients with chronic lung disease (CLD), such as asthma or chronic obstructive pulmonary disease, were expected to have an increased risk of clinical manifestations and severity of COVID-19. However, these comorbidities have been reported less frequently than expected. Chronic treatment with inhaled corticosteroids (ICS) may impact the clinical course of COVID-19. The main objective of this study is to know the influence of chronic treatment with ICS on the prognosis of COVID-19 hospitalized patients with CLD. Methods: A multicenter retrospective cohort study was designed, including patients hospitalized with COVID-19. Epidemiological and clinical data were collected at admission and at seven days, and clinical outcomes were collected. Patients with CLD with and without chronic treatment with ICS were compared. Results: Two thousand five hundred ninety-eight patients were included, of which 1,171 patients had a diagnosis of asthma and 1,427 of COPD (53.37% and 41.41% with ICS, respectively). No differences were found in mortality, transfer to ICU, or development of moderate-severe ARDS. Patients with chronic ICS had a longer hospital stay in both asthma and COPD patients (9 vs. 8 days, p = 0.031 in asthma patients), (11 vs. 9 days, p = 0.018 in COPD patients); although they also had more comorbidity burden. Conclusions: Patients with chronic inhaled corticosteroids had longer hospital stays and more chronic comorbidities, measured by the Charlson comorbidity index, but they did not have more severe disease at admission, evaluated with qSOFA and PSI scores. Chronic treatment with inhaled corticosteroids had no influence on the prognosis of patients with chronic lung disease and COVID-19.

Usefulness of Systemic Venous Ultrasound Protocols in the Prognosis of Heart Failure Patients: Results from a Prospective Multicentric Study.

Mortality and re-admission rates for decompensated acute heart failure (AHF) is increasing overall and risk stratification might be challenging. We sought to evaluate the prognostic role of systemic venous ultrasonography in patients hospitalized for AHF. We prospectively recruited 74 AHF patients with a NT-proBNP level above 500 pg/mL. Then, multi-organ ultrasound assessments (lung, inferior vena cava (IVC), pulsed-wave Doppler (PW-Doppler) of hepatic, portal, intra-renal and femoral veins) were performed at admission, discharge, and follow-up (for 90 days). We also calculated the Venous Excess Ultrasound System (VExUS), a new score of systemic congestion based on IVC dilatation and pulsed-wave Doppler morphology of hepatic, portal and intra-renal veins. An intra-renal monophasic pattern (area under the curve (AUC) 0.923, sensitivity (Sn) 90%, specificity (Sp) 81%, positive predictive value (PPV) 43%, and negative predictive value (NPV) 98%), a portal pulsatility > 50% (AUC 0.749, Sn 80%, Sp 69%, PPV 30%, NPV 96%) and a VExUS score of 3 corresponding to severe congestion (AUC 0.885, Sn 80%, Sp 75%, PPV 33%, and NPV 96%) predicted death during hospitalization. An IVC above 2 cm (AUC 0.758, Sn 93.l% and Sp 58.3) and the presence of an intra-renal monophasic pattern (AUC 0. 834, sensitivity 0.917, specificity 67.4%) in the follow-up visit predicted AHF-related re-admission. Additional scans during hospitalization or the calculation of a VExUS score probably adds unnecessary complexity to the assessment of AHF patients. In conclusion, VExUS score does not contribute to the guidance of therapy or the prediction of complications, compared with the presence of an IVC greater than 2 cm, a venous monophasic intra-renal pattern or a pulsatility > 50% of the portal vein in AHF patients. Early and multidisciplinary follow-up visits remain necessary for the improvement of the prognosis of this highly prevalent disease.

Prediction Accuracy of Serial Lung Ultrasound in COVID-19 Hospitalized Patients (Pred-Echovid Study).

The value of serial lung ultrasound (LUS) in patients with COVID-19 is not well defined. In this multicenter prospective observational study, we aimed to assess the prognostic accuracy of serial LUS in patients admitted to hospital due to COVID-19. The serial LUS protocol included two examinations (0-48 h and 72-96 h after admission) using a 10-zones sequence, and a 0 to 5 severity score. Primary combined endpoint was death or the need for invasive mechanical ventilation. Calibration (Hosmer-Lemeshow test and calibration curves), and discrimination power (area under the ROC curve) of both ultrasound exams (SCORE1 and 2), and their difference (DIFFERENTIAL-SCORE) were performed. A total of 469 patients (54.2% women, median age 60 years) were included. The primary endpoint occurred in 51 patients (10.9%). Probability risk tertiles of SCORE1 and SCORE2 (0-11 points, 12-24 points, and ≥25 points) obtained a high calibration. SCORE-2 showed a higher discrimination power than SCORE-1 (AUC 0.72 (0.58-0.85) vs. 0.61 (0.52-0.7)). The DIFFERENTIAL-SCORE showed a higher discrimination power than SCORE-1 and SCORE-2 (AUC 0.78 (0.66-0.9)). An algorithm for clinical decision-making is proposed. Serial lung ultrasound performing two examinations during the first days of hospitalization is an accurate strategy for predicting clinical deterioration of patients with COVID-19.

Angiomiolipoma renal con invasión de vena renal y vena cava inferior. Presentación de un caso y revisión de la literatura / Renal Angiomyolipoma with Extension to Renal and Cava Veins. A Case Report and Revision of the Literature

Introducción El angiomiolipoma es un tumor benigno cuya presentación con invasión del seno renal y formación de trombo venoso tumoral es muy infrecuente, habiéndose descrito aproximadamente 50 casos desde que en 1982 Kutcher describiera el primero. Reporte de caso Presentamos un caso angiomiolipoma renal con afectación venosa diagnosticado mediante TAC a partir del hallazgo de trombo venoso en ecografía y resonancia en una paciente de 43 años embarazada y asintomática que presentó elevación de transminasas en una analítica. Ante la posibilidad de que se tratara de una variante epitelioide y/o clásica con potencial de malignización, se decidió tratamiento mediante nefrectomía y trombectomía abierta, sin incidencias intra ni postoperatorias. La paciente se encuentra asintomática tras 6 meses de seguimiento. La histología fue compatible con angiomiolipoma clásico con trombo venoso. Conclusión La invasión de vena renal por un angiomiolipoma es extremadamente rara. Aunque infrecuente, habría que considerar la posibilidad de malignización para no demorar su tratamiento

Introduction Angiomyolipoma is a benign kidney tumour that rarely affects the renal sinus or the renal or caval vein. Kutcher made the first case report in 1982, and since then there have been described approximately 50 cases. Case Report We present a case of angiomyolipoma with venous thrombus in a 43 years-old asymptomatic pregnant woman who presented elevation of transaminases in a blood test, with an ultrasonography that showed a venous thrombus without any renal mass, being diagnosed after giving birth by scanner. Having in account the possibility of malignancy of the mass, we performed surgical treatment by open radical nephrectomy and thrombectomy, without intraoperative nor postoperative incidences. The patient remains asymptomatic 6 months after surgery. The histology was compatible with classic angiomyolipoma with venous thrombus. Conclussion Angiomyolipoma causing venous invasion is extremely rare, but we should take into consideration its possibility of malignancy in order to treat it as soon as possible

La enseñanza de la práctica clínica en la Facultad de Medicina de la Universidad Complutense de Madrid / Teaching of clinical practice in the Faculty of Medicine of the Complutense University of Madrid

Se describe la metodología de instrucción y evaluación en práctica clínica y el grado de implicación del profesorado en esta tarea en la Unidad Docente del Hospital 12 de Octubre (Facultad de Medicina, Universidad Complutense de Madrid). A pesar de algunas disfunciones curriculares, nuestros estudiantes alcanzan un buen nivel de competencia clínica al final del grado. Algunos profesores tienen un conocimiento limitado de los roles docentes que pueden asumir, por lo que deberían recibir formación específica. Idealmente, la enseñanza clínica ha de implicar a todos los profesionales que cuidan del paciente en el contexto extra- e intrahospitalario

We describe the methodology for instruction and assessment of clinical practice and analyze the profile and teaching roles of faculty at the Teaching Unit of the Hospital 12 de Octubre (Faculty of Medicine, Complutense University of Madrid). Despite some structural limitations in curriculum development our students reach a good final level of clinical competence. The need for trainers to understand the different roles they can assume, improving faculty development and involving all the professionals taking care of the patient in the teaching process are emphasized

Basic Abdominal Point-of-Care Ultrasound Training in the Undergraduate: Students as Mentors.

OBJECTIVES: To analyze the ability of medical students to be integrated in the teaching of basic abdominal ultrasound using a peer-mentoring design. METHODS: Thirty medical students previously trained in basic abdominal ultrasound (mentors) had to teach all fourth-year students (n = 136) from a single academic year the same training they had received. There were 3 stages to the ultrasound teaching: theoretical (online course); basic training (3 practical sessions in which students were guaranteed to have had a minimum of 15 hours of practical experience with ultrasound and performed at least 20 basic abdominal ultrasound studies); and evaluation (objective structured clinical examination in which students had to obtain the basic abdominal views and to identify 17 structures). RESULTS: The mean grade ± SD obtained was 8.71 ± 1.53 of a possible 10 points. Only 2 students (1.56%) obtained a grade lower than 5, and 14 students (10.86%) obtained a grade lower than 7. A total of 33 students (25.5%) achieved the maximum grade. The structures most easily identified were the liver, the right kidney, and the urinary bladder, with 97.7% of correct answers. Students obtained the poorest results when trying to identify the left and right cardiac cavities (subxiphoid view), with only 53.5% and 55.8% of correct answers, respectively. CONCLUSIONS: Teaching based on peer mentoring achieved an adequate level of training in basic abdominal ultrasound. The students acquired these skills in a relatively short training period. These results suggest that peer mentoring can facilitate the large-scale implementation of ultrasound teaching in undergraduate students.

Ultrasound for the diagnosis of infectious diseases: Approach to the patient at point of care and at secondary level.

Bedside ultrasound evaluation for infection can be performed promptly at the bedside, using simple equipment and without irradiation. Visualization of the foci often enables prompt antimicrobial therapy and even early ultrasound-guided procedure, facilitating earlier confirmation. These procedures are made safer using the real-time visual control that ultrasound provides. Future challenges for an infectious diseases specialist include gaining experience about the appropriate use of point-of-care ultrasound (POCUS). Ultrasonography training is required to ensure competent use of this technology.
