Elevated levels of serum CDCP1 in individuals recovering from severe COVID-19 disease.

BACKGROUND: COVID-19 survivors report residual lung abnormalities after discharge from the hospital. The aim of this study was to identify biomarkers in serum and induced sputum samples from patients after hospitalization for COVID-19. METHODS: Patients admitted to hospitals in Spain with laboratory-confirmed COVID-19 were recruited for this study. SARS-CoV-2-infected patients were divided into groups with mild/moderate and severe disease according to the severity of their symptoms during hospitalization. Levels of 92 biomarkers were measured in serum and induced sputum samples. RESULTS: A total of 108 patients (46.2% severe cases) were included in this study. The median number of days after the onset of symptoms was 104. A significant difference was observed in diffusing capacity for carbon monoxide (DLCO), an indicator of lung function, whereby DLCO <80% was significantly lower in severe cases (p <0.001). Differences in inflammatory biomarkers were observed between patients with mild/moderate and severe disease. For some biomarkers, correlations in serum and induced sputum levels were detected. Independent predictors of severe disease were DLCO <80% and the serum CDCP1 value. CONCLUSIONS: Higher levels of CDCP1 remain after hospital discharge and are associated with the severity of COVID-19. The possible prognostic implications warrant further investigation.

Pulmonary long-term consequences of COVID-19 infections after hospital discharge.

OBJECTIVES: Coronavirus disease 2019 (COVID-19) survivors are reporting residual abnormalities after discharge from hospital. Limited information is available about this stage of recovery or the lingering effects of the virus on pulmonary function and inflammation. This study aimed to describe lung function in patients recovering from COVID-19 hospitalization and to identify biomarkers in serum and induced sputum samples from these patients. METHODS: Patients admitted to Spanish hospitals with laboratory-confirmed COVID-19 infection by a real-time PCR (RT-PCR) assay for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were recruited for this study. Each hospital screened their lists of discharged patients at least 45 days after symptom onset. SARS-CoV-2-infected patients were divided into mild/moderate and severe disease groups according to the severity of their symptoms during hospitalization. Patients' epidemiological and medical histories, comorbidities, chronic treatments, and laboratory parameters were evaluated. Pulmonary function tests, the standardized 6-minute walk test (6MWT) and chest computed tomography (CT) were also performed. The levels of proteases, their inhibitors, and shed receptors were measured in serum and induced sputum samples. RESULTS: A total of 100 patients with respiratory function tests were included in this study. The median number of days after the onset of symptoms was 104 (IQR 89.25, 126.75). COVID-19 was severe in 47% of patients (47/100). CT was normal in 48% of patients (48/100). Lung function was normal forced expiratory volume in one second (FEV1) ≥80%, forced vital capacity (FVC) ≥80%, FEV1/FVC ≥0.7, and diffusing capacity for carbon monoxide (DLCO) ≥80% in 92% (92/100), 94% (94/100), 100% (100/100) and 48% (48/100) of patients, respectively. Multivariate analysis showed that a DLCO <80% (OR 5.92; 95%CI 2.28-15.37; p < 0.0001) and a lower serum lactate dehydrogenase level (OR 0.98; 95%CI 0.97-0.99) were associated with the severe disease group of SARS-CoV-2 cases during hospital stay. CONCLUSIONS: A diffusion deficit (DLCO <80%) was still present after hospital discharge and was associated with the most severe SARS-CoV-2 cases.

Coronary computed tomographic angiography findings and their therapeutic implications in asymptomatic patients with familial hypercholesterolemia. Lessons from the SAFEHEART study.

BACKGROUND: Familial hypercholesterolemia (FH) confers an increased risk of premature atherosclerotic disease. Coronary computed tomographic angiography (CTA) can assess preclinical coronary atherosclerosis. OBJECTIVES: To describe coronary CTA findings in asymptomatic molecularly defined FH individuals, to identify those factors related to its presence and extension, and to assess the impact of these results in patients' care and estimated risk. METHODS: Four hundred and forty individuals with FH, without clinical cardiovascular disease, were consecutively enrolled and underwent a coronary CTA that was used to analyze coronary atherosclerosis based on coronary calcium score (CCS), sum of stenosis severity, and plaque composition sum (PCS). For FH patients, cardiovascular risk was estimated using the specific SAFEHEART risk equation. Follow-up was performed using a standardized protocol. RESULTS: Mean age was 46.4 years (231 women, 52%). Coronary calcium was present in 55%, mean CCS was 130.9, 46% had a plaque with lumen involvement, and mean PCS was 1.1. During follow-up, there were 17 (4%) nonfatal events and 2 (1%) fatal events. CCS was independently associated to the estimated risk and low-density lipoprotein-cholesterol life-years, sum of stenosis severity to the estimated risk, and PCS to the estimated risk and low-density lipoprotein-cholesterol life-years. CTA findings induced a positive change in patients' care and in their estimated risk. CONCLUSION: Coronary artery atherosclerosis is highly prevalent in asymptomatic patients with FH and it is independently associated to cardiovascular risk. More advanced disease on CTA was associated with subsequent intensification of therapy and reduction of estimated risk. Further longitudinal studies are required to know if these findings might improve the risk stratification in patients with FH.

Intimal sarcoma of the pulmonary artery with multiple lung metastases: Long-term survival case.

Pulmonary artery intimal sarcoma (PAIS) is a rare tumor with a very poor prognosis. Clinical and radiological findings usually mimic thromboembolic disease, leading to diagnostic delays. The treatment of choice is surgery, and adjuvant chemotherapy and radiotherapy have limited results. We report the case of a 48-year-old male patient, initially suspected with pulmonary thromboembolism. The angio-CT revealed a filling defect in the pulmonary artery trunk. The patient underwent surgery, resulting in with complete resection of the mass with a diagnosis of PAIS. The tumor progressed rapidly in the lung, requiring surgery of multiple lung metastases. The patient was treated with stereotactic body radiation therapy (SBRT) on two occasions for new pulmonary lesions. In the last followup (4 years after initial diagnosis), the patient was disease-free. In conclusion, SBRT proved to be an alternative treatment to metastasectomy, allowing palliative chemotherapy to be delayed or omitted, which may result in improved quality of life.

Modificación de la conducción auriculoventricular tras el implante de prótesis aórtica Core Valve / Atrioventricular conduction changes after corevalve transcatheter aortic valve implantation

Introducción y objetivos: Con frecuencia se producen alteraciones en la conducción tras el implante de una prótesis CoreValve. Se pretende analizar qué cambios se producen en la conducción cardiaca de pacientes con estenosis aórtica tratados con este tipo de prótesis. Métodos: Desde abril de 2008 hasta diciembre de 2013, se seleccionó a 181 pacientes con estenosis aórtica grave tratados con esta prótesis y estudiados mediante electrocardiograma. Se estudió a un subgrupo de 137 pacientes consecutivos (75,7%) mediante electrocardiogramas intracavitarios antes y tras implante protésico. El objetivo principal del estudio es la necesidad de marcapasos definitivo en las primeras 72 h tras el implante protésico. Se analizaron numerosas variables para predecir esta eventualidad. Resultados: Tras el implante, los intervalos PR y QRS se incrementaron de 173 ± 47 a 190 ± 52 ms (p < 0,01) y de 98 ± 22 a 129 ± 24 ms (p < 0,01), mientras que los intervalos AH y HV se alargaron de 95 ± 39 a 108 ± 41 ms (p < 0,01) y de 54 ± 10 a 66 ± 23 ms (p < 0,01). En total, 89 pacientes (49%) presentaron bloqueo de rama izquierda de novo y 33 (25%) precisaron marcapasos en las primeras 72 h. Los predictores independientes de marcapasos fueron el bloqueo de rama derecha basal y la profundidad protésica. Los intervalos intracavitarios carecieron de valor predictivo. Además, 13 pacientes requirieron marcapasos después de las 72 h. Conclusiones: El implante de prótesis CoreValve produce alta incidencia de alteraciones de la conducción; la más frecuente es el bloqueo de rama izquierda; el 25% de los pacientes precisaron marcapasos definitivo. La necesidad de marcapasos se relacionó con el bloqueo de rama derecha basal y la profundidad protésica (AU)

Introduction and objectives: Conduction disturbances often occur after CoreValve transcatheter aortic valve implantation. The aim was to analyze which cardiac conduction changes occur in patients with aortic stenosis treated with this type of prosthesis. Methods: A total of 181 patients with severe aortic stenosis treated with this prosthesis and studied by electrocardiography between April 2008 and December 2013 were selected. A subgroup of 137 (75.7%) consecutive patients was studied by intracardiac electrocardiogram before and after prosthesis implantation. The primary endpoint of the study was the need for a permanent pacemaker within 72 hours after prosthesis implantation. Numerous variables to predict this possibility were analyzed. Results: Following implantation, PR and QRS intervals were increased from 173 ± 47 ms to 190 ± 52 ms (P < .01) and from 98 ± 22 ms to 129 ± 24 ms (P < .01), whereas the A-H and H-V intervals were prolonged from 95 ± 39 ms to 108 ± 41 ms (P < .01) and from 54 ± 10 ms to 66 ± 23 ms (P < .01). A total of 89 (49%) patients had new-onset left bundle-branch block, and 33 (25%) required a pacemaker within the first 72 hours. The independent predictors for a pacemaker were baseline right bundle-branch block and prosthetic depth. Intracardiac intervals had no predictive value. In addition, 13 patients required a pacemaker after 72 hours. Conclusions: CoreValve prosthesis implantation has a high incidence of conduction disturbance, with left bundle-branch block being the most common. A total of 25% of patients required a permanent pacemaker. The need for a pacemaker was related to baseline right bundle-branch block and prosthetic depth (AU)

Stent Repair for Complex Coarctation of Aorta.

OBJECTIVES: This study sought to determine whether several anatomic or evolving characteristics of the coarctation may create challenging conditions for treatment. BACKGROUND: Stent repair of coarctation of aorta is an alternative to surgical correction. METHODS: We analyzed our 21-year experience in the percutaneous treatment of complex coarctation of aorta. Adverse conditions for treatment were as follow: 1) complete interruption of the aortic arch (n = 11); 2) associated aneurysm (n = 18); 3) complex stenosis (n = 30); and 4) the need for re-expansion and/or restenting (n = 21). Twenty patients (33%) belonged to more than 1 group. Ten interruptions were type A and 1 was type B. The mean length of the interrupted aorta was 9 ± 11 mm. The associated aneurysms were native in 8 patients and after previous intervention in 10 patients. Aneurysm shapes were fusiform in 8 patients and saccular in 10. The following characteristics defined complex stenosis as long diffuse stenosis, very tortuous coarctation, or stenosis involving a main branch or an unusual location. Patients previously stented at an early age, required re-expansion and/or restenting after reaching 16 ± 5 years of age. RESULTS: Two patients had died by 1-month follow-up. The remaining 58 patients did well and were followed-up for a mean period of 10 ± 6 years. Late adverse events occurred in 3 patients (5%). All remaining patients are symptom-free, with normal baseline blood pressure. Imaging techniques revealed good patency at follow-up without associated aneurysm or restenosis. The actuarial survival free probability of all complex patients at 15 years was 92%. CONCLUSIONS: Stent repair of complex coarctation of aorta is feasible and safe. Initial results are maintained at later follow-up.

Indicaciones de la resonancia magnética en el diagnóstico ginecológico / Indications for magnetic resonance imaging in gynecological diagnosis

El papel de la resonancia magnética (RM) en ginecología, especialmente en el campo de la ginecología oncológica, ha ido adquiriendo una creciente importancia durante las dos últimas décadas. En el momento actual existe una sólida evidencia científica que apoya su uso en la patología pélvica tumoral, inflamatoria y malformativa. Datos recientes apoyan además un creciente papel en el estudio de la patología mamaria. En cualquier caso, y tal y como analizaremos en nuestro trabajo, su aplicabilidad en el ámbito de nuestra especialidad parece ir aumentando progresivamente, haciendo de esta técnica de imagen una prueba complementaria más, aplicable al estudio de la fisiopatología del tracto genital (AU)

The role of magnetic resonance imaging (MRI) in gynecology has become increasingly important in the last few decades, especially in gynecologic oncology. Currently, there is strong evidence to support the use of this imaging modality in distinct pelvic diseases such as tumors, inflammations and malformations. Recent studies support a growing role for MRI in the diagnosis of breast disease. As shown in the present review, the applicability of MRI in the physiopathology of genital tract diseases seems to be progressively increasing. MRI should therefore be considered as one more option that can be employed in gynecology (AU)
