Influence of Donor Type-Donation After Brain Death Versus Donation After Circulatory Death-on Lung Transplant Outcomes.

BACKGROUND: We sought to analyze the influence of lung donor type (brain death [BD] vs controlled donation after cardiac death [DCD]) on lung graft viability and to compare short-term outcomes of lung transplantation using grafts from BD and DCD donors. METHODS: This was a retrospective study of the lung donor population and lung transplants performed at our Institution between January 2020 and December 2022. Demographic characteristics of the donors and donation type (BD vs DCD) were assessed. Lung graft viability rate and post-transplant outcomes were analyzed and compared between donor types. RESULTS: There were 203 donors; among them, 149 (73%) were viable. There were 176 BD donors (87%) and 27 DCD donors (13%), with viability rates of 75% and 59%, respectively, performing 81 single (40%) and 122 double-lung transplants (60%). Recipient PaO2/fraction of inspired oxygen and primary graft dysfunction at 24 and 72 hours did not differ between donor types. Thirty-day mortality did not differ between recipients from BD donors and recipients from DCD donors: n = 28 (21%) vs n = 3 (18%), respectively (P = .81). CONCLUSIONS: Donation after cardiac death donors is a safe source to increase the donor pool for lung transplantation, allowing similar short-term outcomes as lung transplants from BD donors regarding graft function and early survival.

Surgical Complications After Lung Transplantation: The Reina Sofía Hospital Experience.

OBJECTIVE: To assess the incidence of surgical complications after lung transplantation and its influence on early mortality and long-term survival. METHODS: Retrospective review of 792 lung transplants (LTs) performed from 1994 to 2022. Among them, 769 with complete data were selected. Patients with and without surgical complications were compared by univariable and multivariable analyses. RESULTS: There were 385 single LTs (50%), 371 double LTs (48%), 8 bilobar LTs (1%), and 5 combined liver LTs (1%). Two hundred forty-nine patients presented surgical complications (32%) as follows: bronchial (n = 61), vascular (n = 55), pneumothorax (n = 33), and phrenic nerve palsy (n = 22). Thirty-day mortality (noncomplicated vs complicated) was 57 (41%) vs 80 (59%), P < .001. Transplants for bronchiectasis (58%), pulmonary hypertension (50%), and re-transplants (78%) presented more surgical complications (P < .001). Double LT (40%), bilobar LT (88%), and combined liver LT (100%) presented more surgical complications (P < .001). Complicated recipients were younger (49 ± 15 vs 45 ± 17 years; P = .001), with longer ischemic times (429 ± 67 vs 450 ± 76 min [2nd graft]; P = .007), and required extracorporeal support (ECLS) more often (43% vs 57%; P < .001). Survival at 1, 5, 10, 15, and 20 years (noncomplicated vs complicated): 78%, 63%, 52%, 41%, 31% vs 52%, 42%, 35%, 26%, 22%; P < .001). Predictors of mortality were the need for ECLS (odds ratio [OR] 4.14; P < .001), postoperative ventilation (hours) (OR 1.01; P < .001), and vascular complications (OR 4.78; P < .001). CONCLUSION: Surgical complications remain an important source of morbidity and mortality after lung transplantation. Complex surgical procedures requiring ECLS develop frequent surgical complications needing long postoperative ventilation that are associated with early mortality and poorer long-term survival.

Case Report of Complex Chest Wall Repair for Sternal Dehiscence After Bilateral Lung Transplantation.

BACKGROUND: We report a case of a complex chest wall reconstruction because of sternal dehiscence, requiring different surgical procedures for its complete resolution. CASE REPORT: A 54-year-old man patient with Langerhans cell histiocytosis and chronic obstructive pulmonary disease underwent bilateral sequential lung transplantation through a clamshell incision, using nitinol thermo-reactive clips for sternal closure. One year later, he consulted because of chest pain, fever, and purulent secretions. Physical examination and chest X-ray revealed a right pulmonary hernia due to post-clamshell wound dehiscence. Chest wall repair was performed, placing an expanded-polytetrafluoroethylene synthetic mesh, and the sternum was realigned and fixated with titanium plates and screws. However, in the immediate postoperative period, there was a large amount of serous drainage through the surgical wound, needing negative pressure therapy. Unfortunately, the wound became necrotic with exposure to the osteosynthesis material. In addition, a chest computed tomography scan showed fluid accumulation in the anterior chest wall. Therefore, two-stage revision surgery was indicated: first, the removal of the previous prosthesis and, the definite one, the use of a pedicled latissimus dorsi myocutaneous flap to provide effective coverage of the wound. CONCLUSION: Sternal dehiscence is not an uncommon complication after clamshell incision in patients undergoing bilateral sequential lung transplantation, and it is associated with significant morbidity. In the presence of chest wall instability, surgical repair is mandatory.

Disfunción eréctil y YouTube: calidad de los vídeos en español / Erectile dysfunction and YouTube: Quality of videos in Spanish

Introducción: La disfunción eréctil (DE) es una de las enfermedades urológicas más prevalentes, pero los datos de la calidad de su información en redes sociales son escasos. El objetivo de nuestro estudio fue evaluar la calidad de la información sobre DE contenida en los vídeos de YouTube. Material y métodos: Estudio descriptivo transversal de los 50 primeros vídeos en castellano publicados en YouTube, evaluados por tres urólogos mediante dos cuestionarios validados: Patient Education Materials Assessment Tool (PEMAT) y DISCERN, clasificándolos según puntuación DISCERN en calidad pobre y moderada-buena. Resultados: La mediana de duración fue de 2,42 minutos, y la de visualizaciones, de 94.197 (2.313-3.027.890), con 682,5 (0-54.020) «me gusta» y 39 (0-2.843) «no me gusta». La mediana de PEMAT fue del 29% en inteligibilidad y del 29% en factibilidad. Con DISCERN, 27 vídeos (57,4%) fueron de calidad pobre y 20 (42,6%), de calidad moderada-buena. No observamos diferencias significativas entre ambos grupos en duración, visualizaciones, número de «me gusta» o de «no me gusta». Sí existieron diferencias en PEMAT de inteligibilidad y de factibilidad. El 86,7% de los protagonizados por personal médico fueron de calidad moderada-buena (p=0,001). El 85,7% de los que describían el tratamiento fueron de calidad moderada-buena y el 84% de los vídeos no médicos fueron de calidad pobre (p=0,001). Conclusiones: La mayoría de los vídeos sobre DE en YouTube son de calidad pobre. Los vídeos de mayor calidad son aquellos realizados por profesionales, aunque no son los más vistos. Sería importante el desarrollo de medidas para evitar la difusión de desinformación entre los usuarios de redes sociales. (AU)

Introduction: Erectile dysfunction (ED) is one of the most prevalent urological diseases, but there is limited data about the quality of its information in social networks. The aim of our study was to assess the quality of ED information contained in YouTube videos. Material and methods: Descriptive study of the first 50 Spanish-language videos, published on YouTube, evaluated by three urologists. We used two validated questionnaires: PEMAT (Patient Education Materials Assessment Tool) and DISCERN. Videos were classified according to DISCERN score into poor or moderate-good quality. Results: The median time duration was 2.42minutes (0.15-3.58), 94,197 views (2,313-3,027,890), 682.5 «likes» (0-54,020) and 39 «dislikes» (0-2843). The median of PEMAT score was 29% (9%-95.5%) in understandability and 29% (0-95.5%) in actionability. According to DISCERN score 27 videos (57.4%) had poor quality and 20 (42.6%) moderate-good quality. There were no significant differences between the two groups in time duration, views, «likes» or «dislikes». There were differences in PEMAT score in understandability and actionability. The 86.7% of the moderate-good quality videos were starred by health care provider (P=.001). Also, the 85.7% of videos that describes treatment had moderate-good quality (P=.001). The 84% of the non-medical videos had a poor quality (P=.001). Conclusion: Most ED videos on YouTube have poor quality. The highest quality videos are those made by professionals, although they are not the most viewed. It would be important to develop measures to prevent the spread of misinformation among social network users. (AU)

Influence of De Novo Malignancies on Long-Term Survival after Lung Transplantation.

(1) Background: Malignancies are an important cause of mortality after solid organ transplantation. The purpose of this study was to analyze the incidence of malignancies in patients receiving lung transplants (LT) and their influence on patients' survival. (2) Methods: Review of consecutive LT from 1994 to 2021. Patients with and without malignancies were compared by univariable and multivariable analyses. Survival was compared with Kaplan-Meier and Cox regression analysis. (3) Results: There were 731 LT malignancies developed in 91 patients (12.4%) with related mortality of 47% (n = 43). Native lung cancer, digestive and hematological malignancies were associated with higher lethality. Malignancies were more frequent in males (81%; p = 0.005), transplanted for emphysema (55%; p = 0.003), with cyclosporine-based immunosuppression (58%; p < 0.001), and receiving single LT (65%; p = 0.011). Survival was worse in patients with malignancies (overall) and with native lung cancer. Risk factors for mortality were cyclosporine-based immunosuppression (OR 1.8; 95%CI: 1.3-2.4; p < 0.001) and de novo lung cancer (OR 2.6; 95%CI: 1.5-4.4; p < 0.001). (4) Conclusions: Malignancies are an important source of morbidity and mortality following lung transplantation that should not be neglected. Patients undergoing single LT for emphysema are especially at higher risk of mortality due to lung cancer in the native lung.

Quality of bladder cancer information on YouTube.

Introduction: YouTube is one of the social networks most widely used as a source of information. However, there are doubts about the scientific quality of the information available. This study aims to characterise this by analysing videos about bladder cancer posted on YouTube. Material and methods: This was a cross-sectional descriptive study of the first 50 Spanish-language videos published on YouTube, leaving 38 for analysis. The videos were evaluated by three urologists using two validated questionnaires: Patient Education Materials Assessment Tool (PEMAT) and DISCERN (quality criteria for consumer health information), classifying them according to the score of the latter, in poor quality (1-2 points) and moderate/good quality (3-5 points). Results: The median PEMAT score was 71.6% (16-5-100%) for understanding and 35.5% (0-100%) for action. According to DISCERN, 26 videos (66.7%) were of poor quality and 12 (30.8%) of moderate/good quality. We found significant differences in terms of PEMAT of understanding (p = 0.004) and action (p = 0.000). In total, 90.9% of those involving medical staff were of low quality, which is paradoxical, but statistically significant (p = 0.01). Furthermore, 52.4% of those describing relevant information were of moderate/good quality, and 94.1% of those not describing relevant information were of poor quality (p = 0.02). Conclusions: More than 60% of the videos published on YouTube about bladder cancer in Spanish are of low quality. This represents an important risk of misinformation for the general public to whom most of them are addressed.

Lung Transplantation in a Young Patient With Pulmonary Artery Hypertension After Arterial Switch Operation: A Case Report.

Pulmonary hypertension after surgical correction of D-transposition of the great vessels is a rare but serious complication. Lung transplantation may be the only option when treatment with vasodilators is insufficient. We present the case of a young male patient with a history of arterial switch in neonatal period who undergoes double lung transplantation owing to late pulmonary hypertension.

Incidence of Carcinoma in the Native Lung After Single Lung Transplantation.

BACKGROUND: This study aims to assess the incidence of primary lung cancer in the native lung and its impact on survival in patients undergoing single lung transplantation (SLT). METHODS: This study retrospectively analyzed 161 SLTs performed between June 2012 and June 2019. The incidence of carcinoma in the native lung and its influence on patient survival was determined. Recipient variables, tumor stage, and survival were analyzed and compared between patients with and without native lung cancer. The analysis was adjusted for transplant indication. Both univariable and multivariable analyses were performed. The present study followed the Declaration of Helsinki Ethical Principles for Medical Research involving human subjects. RESULTS: There were 161 patients (126 men/35 women; 57 ± 7 years) transplanted for chronic obstructive pulmonary disease (COPD) (n = 72), idiopathic pulmonary fibrosis (IPF) (n = 77), or other indications (n = 12). Eleven patients with COPD (7%) developed lung cancer in the native lung after SLT. Lung cancer did not appear in any of the SLTs for pulmonary fibrosis. Five participants were in stages I/II and underwent lung resection, and 6 participants were in stages III/IV and underwent chemotherapy/radiotherapy. Survival (1, 3, and 5 years) without vs with native lung carcinoma in patients with COPD was 89%, 86%, and 80% vs 86%, 71%, and 51% (P = .04). The occurrence of carcinoma in the native lung predicted survival in patients with COPD (odds ratio [OR]: 2.55; P = .07). CONCLUSIONS: Lung cancer in the native lung is a frequent and devastating complication after SLT in patients with COPD, which might negatively affect long-term survival. This should be considered when choosing the transplant procedure for patients with COPD.

The influence of the native lung on early outcomes and survival after single lung transplantation.

OBJECTIVE: To determine whether problems arising in the native lung may influence the short-term outcomes and survival after single lung transplantation (SLT), and therefore should be taken into consideration when selecting the transplant procedure. PATIENTS AND METHODS: Retrospective review of 258 lung transplants performed between June 2012 and June 2019. Among them, 161 SLT were selected for the analysis. Complications in the native lung were recorded and distributed into two groups: early and late complications (within 30 days or after 30 days post-transplant). Donor and recipient preoperative factors, 30-day mortality and survival were analysed and compared between groups by univariable and multivariable analyses, and adjusting for transplant indication. RESULTS: There were 161 patients (126M/35F; 57±7 years) transplanted for emphysema (COPD) (n = 72), pulmonary fibrosis (IPF) (n = 77), or other indications (n = 12). Forty-nine patients (30%) presented complications in the native lung. Thirty-day mortality did not differ between patients with or without early complications (6% vs. 12% respectively; p = 0.56). Twelve patients died due to a native lung complication (7.4% of patients; 24% of all deaths). Survival (1,3,5 years) without vs. with late complications: COPD (89%, 86%, 80% vs. 86%, 71%, 51%; p = 0.04); IPF (83%, 77%, 72% vs. 93%, 68%, 58%; p = 0.65). Among 30-day survivors: COPD (94%, 91%, 84% vs. 86%, 71%, 51%; p = 0.01); IPF (93%, 86%, 81% vs. 93%, 68%, 58%; p = 0.19). Native lung complications were associated to longer ICU stay (10±17 vs. 33±96 days; p<0.001), longer postoperative intubation (41±85 vs. 99±318 hours; p = 0.006), and longer hospital stay (30±24 vs. 45±34 days; p = 0.03). The presence of late native lung problems predicted survival in COPD patients (OR: 2.55; p = 0.07). CONCLUSION: The native lung is a source of morbidity in the short-term and mortality in the long-term after lung transplantation. This should be taken into consideration when choosing the transplant procedure, especially in COPD patients.

High-dose corticosteroid pulse therapy increases the survival rate in COVID-19 patients at risk of hyper-inflammatory response.

OBJECTIVE: Test whether high dose corticosteroid pulse therapy (HDCPT) with either methylprednisolone or dexamethasone is associated with increased survival in COVID-19 patients at risk of hyper-inflammatory response. Provide some initial diagnostic criteria using laboratory markers to stratify these patients. METHODS: This is a prospective observational study, 318 met the inclusion criteria. 64 patients (20.1%) were treated with HDCPT by using at least 1.5mg/kg/24h of methylprednisolone or dexamethasone equivalent. A multivariate Cox regression (controlling for co-morbidities and other therapies) was carried out to determine whether HDCPT (among other interventions) was associated with decreased mortality. We also carried out a 30-day time course analysis of laboratory markers between survivors and non-survivors, to identify potential markers for patient stratification. RESULTS: HDCPT showed a statistically significant decrease in mortality (HR = 0.087 [95% CI 0.021-0.36]; P < 0.001). 30-day time course analysis of laboratory marker tests showed marked differences in pro-inflammatory markers between survivors and non-survivors. As diagnostic criteria to define the patients at risk of developing a COVID-19 hyper-inflammatory response, we propose the following parameters (IL-6 > = 40 pg/ml, and/or two of the following: C-reactive protein > = 100 mg/L, D-dimer > = 1000 ng/ml, ferritin > = 500 ng/ml and lactate dehydrogenase > = 300 U/L). CONCLUSIONS: HDCPT can be an effective intervention to increase COVID-19 survival rates in patients at risk of developing a COVID-19 hyper-inflammatory response, laboratory marker tests can be used to stratify these patients who should be given HDCPT. This study is not a randomized clinical trial (RCT). Future RCTs should be carried out to confirm the efficacy of HDCPT to increase the survival rates of COVID-19.

Effectiveness and safety of PCSK9 inhibitors in real-world clinical practice. An observational multicentre study. The IRIS-PCSK9I study.

Background and aims: The benefits of the PCSK9 inhibitors, alirocumab and evolocumab, in lowering LDL-cholesterol and preventing major adverse cardiac events (MACE) have been demonstrated in pivotal clinical trials. However, few studies of routine clinical practice have been conducted to analyse and compare the efficacy and safety of the two drugs. Methods: Retrospective observational study of patients treated with a PCSK9 inhibitor in five hospitals in Andalusia (southern Spain). Baseline demographic and clinical data, LDL-cholesterol levels and the occurrence of MACEs during the follow-up period were recorded. Results: A total of 141 patients were included in the study: 90 were treated with alirocumab and 51 with evolocumab. The patients' mean age (IQR) was 58 (11) years and 58 (41%) were women. The most frequent concomitant medications were statins, 94 (66.7%), followed by antiplatelet therapy (66%) and ezetimibe (65.2%). The median (IQR) follow-up period was 18 (18) months, with 18 (24) for alirocumab and 11 (18) for evolocumab. At the six-month follow-up visit, LDL-cholesterol values had decreased to pre-treatment levels and remained significantly decreased (p < 0.05) over time, for both drugs, and a greater reduction was achieved in patients with established cardiovascular disease and concomitant treatment with statins. With respect to adverse effects, there were nine MACEs (6.4%), of which seven were with alirocumab (7.8%) and two with evolocumab (3.9%) (p NS). Other adverse effects (9.2%) included local erythema (3.5%), muscle cramps (2.1%), respiratory symptoms (2.1%) and asthaenia (1.4%). Conclusions: The efficacy and safety of alirocumab and evolocumab in routine clinical practice are consistent with the findings of the pivotal clinical trials.

Diagnostic Capacity of Pocket-Sized Ultrasound Devices at Point of Care by a Non-radiologist Resident in Patients with Suspected Abdominal Pathology.

Studies have reported the usefulness and tolerability in practice of abdominal ultrasound performed by non-radiologists in various clinical situations. This prospective observational single-center study included 184 patients hospitalized in an internal medicine department who underwent conventional abdominal ultrasound. A medical resident with basic training performed point-of-care clinical ultrasound using a pocket-sized device. The concordance obtained between the researcher and the radiologist was good (k >0.6) for the gallbladder, splenomegaly, longitudinal diameter of the kidney, presence of renal cysts and hydronephrosis. The specificity was >90% for all parameters assessed except normal renal size. A negative predictive value >90% was obtained for all variables studied except the presence of hepatic space-occupying lesions and gallbladder pathology, the negative predictive values for which were >80%. A positive predictive value >80% was obtained for all of these variables, except the presence of adenopathies, hepatomegaly, space-occupying lesions, echogenicity and/or enlargement of the biliary tract, left renal atrophy and right renal masses. We conclude there was a high concordance between a conventional abdominal study and that performed with a pocket-sized ultrasound device after a brief learning curve.
