Aims This study aims to survey current educational experience and the individual requirements for electrophysiologists in training. Methods and results The European Heart Rhythm Association (EHRA) e-Communication Committee and the Scientific Initiatives Committee prepared a questionnaire and distributed it via newsletters, Twitter, LinkedIn, and Facebook. The survey consisted of 22 questions collected on an individual basis anonymously. Two hundred and forty-three responders from 35 countries (32% female, age 38 ± 6 years old) completed the survey. This EHRA electrophysiology (EP) fellowship survey showed that (i) hands-on participation and observation of EP procedures are very important; (ii) the main motivations to choose the EP fellowship institution are centre reputation and volume as well as the availability of a structured EP fellowship programme; (iii) 59% passed the EHRA exam and 46% took a national certification exam; (iv) respondents are overall satisfied with their own fellowships, but there are areas of less confidence such as conduction system pacing implantation and cardiac resynchronization therapy implantation; (v) 78% of respondents performed research during their fellowship, (vi) the optimal duration of an EP fellowship should be at least 2 years; and (viii) doing fellowships abroad is beneficial, but significant obstacles exist. Conclusion The results of this EHRA survey may help to refine current EP fellowship programmes to improve the quality of EP training and early career building of young electrophysiologists.

Social media (SoMe) represents a medium of communication in everyday life and has gained importance for professional use among clinicians. In the #intEHRAct survey, we aimed to describe the use of SoMe by the healthcare community in a professional setting. The EHRA e-Communication Committee and the Scientific Initiatives Committee prepared a questionnaire and distributed it via newsletters, Twitter, LinkedIn, and Facebook. The survey consisted of 19 questions made on an individual basis and collected anonymously. Two hundred and eighty-five responders from 35 countries (72.3% male, age 49 +/- 11 years old) completed the survey. Most respondents (42.7%) declared to use SoMe as passive users while 38.3% and 19.0% declared to share content on a non-daily and daily basis, respectively. The respondents estimated they spent a median of 5 (Q1-Q3: 2-10) h per week on SoMe. The most widely used SoMe was LinkedIn (60.8%), but the use of each platform was heterogeneous between countries. Among the advantages of SoMe, respondents indicated the chance of being updated on recent publications (66.0%), networking (48.5%), and the availability of rare or interesting cases (47.9%) as the most useful. Regarding the disadvantages of SoMe, the respondents underlined the loss of personal contact (40.7%), the inability to get 'hands-on' training (38.7%), and the lack of control regarding quality of scientific evidence (37.1%). Social media is increasingly used for professional purposes for scientific updating, networking, and case-based learning. The results of this survey encourage scientific societies, journals, and authors to enhance the quality, reach and impact of scientific content provided through SoMe.

Since digital devices are increasingly used in cardiology for assessing cardiac rhythm and detecting arrhythmias, especially atrial fibrillation (AF), our aim was to evaluate the expectations and opinions of healthcare professionals in Europe on reimbursement policies for the use of digital devices (including wearables) in AF and other arrhythmias. An anonymous survey was proposed through announcements on the European Heart Rhythm Association website, social media channels, and mail newsletter. Two hundred and seventeen healthcare professionals participated in the survey: 32.7%, reported regular use of digital devices, 45.2% reported that they sometimes use these tools, 18.6% that they do not use but would like to. Only a minority (3.5%) reported a lack of trust in digital devices. The survey highlighted a general propensity to provide medical consultation for suspected AF or other arrhythmias detected by a consumer-initiated use of digital devices, even if time constraints and reimbursement availability emerged as important elements. More than 85% of respondents agreed that reimbursement should be applied for clinical use of digital devices, also in different settings such as post-stroke, post-cardioversion, post-ablation, and in patients with palpitations or syncope. Finally, 73.6% of respondents confirmed a lack of reimbursement fees in their country for physicians' consultations (tracings interpretation) related to digital devices. Digital devices, including wearables, are increasingly and widely used for assessing cardiac rhythm and detecting AF, but a definition of reimbursement policies for physicians' consultations is needed., SCOPUS: ar.j, info:eu-repo/semantics/published

Social media (SoMe) becomes more and more popular in the cardiological community. Among them, Twitter is an emerging and dynamic medium to connect, communicate and educate academic and clinical cardiologists. However, in contrast to traditional scientific communications, the content provided through SoMe is not peer-reviewed and may not necessarily always represent scientific evidence or may even be used to unjustifiably promote therapies for commercial purposes. For the unintended, this means of communication might be appear difficult to handle. This article aims to provide a practical guide on how to use Twitter efficiently for professional use to keep yourself up-to-date about new techniques, the Latest study results and news presented at national or international conferences. Additionally, important limitations will be discussed.

Instant messaging (IM) enables medical professionals to quickly share clinical data to their peers for counselling. Purpose of this survey is to assess the habits related to IM, their application in clinical practice and the perceived pros and cons. An online survey was distributed to the medical community via newsletters, Twitter, Linkedin, and Facebook. The survey consisted of 22 questions made on an individual-basis and collected anonymously on SurveyMonkey. A total of 287 subjects from 33 countries responded to the survey (mean age 43 years, 74.8% male). Of all respondents, 88.3% routinely send and 90.3% receive clinical data through IM which was second only to face-to-face contact as the preferred method for sharing clinical data. Twelve-lead electrocardiograms (88.6%), medical history (61.4%), and echo loops (55.7%) were the data shared most often. Nearly half of the clinical data that are sent (43%) or received (44%) are not anonymized. In the same way, 29.3% of the respondents were not aware of the European General Data Protection Regulation (GDPR) at the time of the survey. IM apps are used by medical professionals worldwide to share and discuss clinical data and are preferred to many other methods of data sharing, being second only to face-to-face contact. IM are often used to share many different types of clinical data, being perceived as a fast and easy way of communication. Medical professionals should be aware of the appropriate use of IM to prevent legal and privacy issues.

The DESERT Underwater framework (http://desert-underwater.dei.unipd.it/), originally designed for simulating and testing underwater acoustic networks in sea trials, has recently been extended to support real payload data transmission through underwater multimodal networks. Specifically, the new version of the framework is now able to transmit data in real time through the EvoLogics S2C low-rate and high-rate acoustic modems, the SmartPORT low-cost acoustic underwater modem prototype (AHOI) for IoT applications, as well as Ethernet, surface WiFi, and the BlueComm optical modem. The system can also be tested in the lab by employing a simulated channel, and the EvoLogics S2C DMAC Emulator (DMACE), Comment: 5 pages, 6 figures

Background: Scientific guidelines consider atrial fibrillation (AF) complicating degenerative mitral regurgitation (DMR) a debated indication for surgery. Objectives: This study analyzed the prognostic/therapeutic implications of AF at DMR diagnosis and long-term. Methods: Patients were enrolled in the MIDA (Mitral Regurgitation International Database) registry, which reported the consecutive, multicenter, international experience with DMR due to flail leaflets echocardiographically diagnosed. Results: Among 2,425 patients (age 67 ± 13 years; 71% male, 67% asymptomatic, ejection fraction 64 ± 10%), 1,646 presented at diagnosis with sinus rhythm (SR), 317 with paroxysmal AD, and 462 with persistent AF. Underlying clinical/instrumental characteristics progressively worsened from SR to paroxysmal to persistent AF. During follow-up, paroxysmal and persistent AF were associated with excess mortality (10-year survival in SR and in paroxysmal and persistent AF was 74 ± 1%, 59 ± 3%, and 46 ± 2%, respectively; p < 0.0001), that persisted 20 years post-diagnosis and independently of all baseline characteristics (p values <0.0001). Surgery (n = 1,889, repair 88%) was associated with better survival versus medical management, regardless of all baseline characteristics and rhythm (adjusted hazard ratio: 0.26; 95% confidence interval: 0.23 to 0.30; p < 0.0001) but post-surgical outcome remained affected by AF (10-year post-surgical survival in SR and in paroxysmal and persistent AF was 82 ± 1%, 70 ± 4%, and 57 ± 3%, respectively; p < 0.0001). Conclusions: AF is a frequent occurrence at DMR diagnosis. Although AF is associated with older age and more severe presentation of DMR, it is independently associated with excess mortality long-term after diagnosis. Surgery is followed by improved survival in each cardiac rhythm subset, but persistence of excess risk is observed for each type of AF. Our study indicates that detection of AF, even paroxysmal, should trigger prompt considerati

Patients with metastatic renal cell carcinoma are at increased risk of bleeding, which must be taken into account if the thromboembolic risk profile requires anticoagulant therapy. Patients treated with sunitinib, especially if with a history of hypertension or coronary artery disease, have a higher risk of cardiovascular events, therefore they should be monitored closely for evidence of worsening arterial hypertension or signs of left ventricular dysfunction. The development of some complications associated with sunitinib increases the thromboembolic risk of patients, who often have to resort to anticoagulant therapy. In the absence of specific guidelines for the management of thromboembolic risk in cancer patients, the therapeutic choice must be guided by the evidence available in the literature to support the individual pharmacological classes. We describe her the case of a patient treated with sunitinib for clear cell renal cell carcinoma, with different comorbidities. The case provides interesting clues for optimal prophylaxis of cardioembolism in cancer patient with atrial fibrillation (Cardiology).

Objetivo: Analizar los resultados de 111 pacientes pediátricos sometidos a enucleación o evisceración en la Clínica Barraquer durante 11 años (1990-2000), determinando tipo de corrección realizada y complicaciones asociadas al procedimiento quirúrgico. Métodos: Estudio retrospectivo de las historias clínicas de todos los pacientes menores de 18 años que fueron sometidos a los procedimientos mencionados, obteniendo datos demográficos,diagnóstico, cirugías oftalmológicas asociadas, características de implantes o injertos, seguimiento y complicaciones postoperatorias en todos los pacientes. Resultados: Se realizaron 55 enucleaciones y 56 evisceraciones. Sólo en un caso no se colocó algún implante o injerto. Durante los primeros 4 años del análisis los injertos lipodérmicos correspondían a un 25,45% y los implantes de Nylon a un 72,72% de las correcciones realizadas, mientras que en los últimos 7 años el implante de hidroxiapatita constituyó el 78,57% de los casos intervenidos. En 17 (15,32%) pacientes se observaron complicaciones que requirieron algún tipo de corrección quirúrgica, sin diferencias estadísticamente significativas entre las distintas correcciones utilizadas. Conclusiones: Para la población pediátrica los implantes de hidroxiapatita, además de brindar una excelente reconstrucción de la órbita anoftálmica, mejoran los resultados estéticos y de motilidad. Sin embargo otro tipo de correcciones como los injertos lipodérmicos siguen constituyendo una excelente alternativa en nuestro medio, teniendo en cuenta que sus costos son mucho menores. Aunque se observaron algunas complicaciones con los diferentes tipos de corrección, muy pocas requirieron una nueva intervención quirúrgica. La tasa de complicaciones se incrementa en pacientes de menos edad., Objective: To analyze the results from 111 pediatric patients who underwent enucleation or evisceration at Barraquer Clinic, during 11 years (1990- 2000), determining the kind of correction used and complications associated with the procedure.Methods: Retrospective study of medical records from all patients under 18 years who underwent mentioned surgery. Demographic data, diagnosis, associated ophthalmic surgeries, implants or grafts characteristics, follow up period and postoperative complications were determined in all patients. Results: A total of 55 enucleations and 56 eviscerations were done. In only one case neither implant nor graft was placed. During the first 4 years of the study, lipodermal grafts corresponded to 25,45% and nylon implants to 72,72% of the totality, while in the last 7 years hydroxyapatite implants corresponded to 78,57% of the cases. 17 patients (15,32%) had complications that required surgical correction, with no significant statistical difference between the types of corrections placed. Conclusions: Hydroxyapatite implants give an excellent anophthalmic orbit reconstruction for pediatric population, and improve esthetic and motility results. Other correction types like lipodermal grafts still constitute an excellent alternative in our environment, considering their lower costs. Although we observed some complications with the different correction methods, only a few cases required surgical intervention. The rate of complications increased in younger patients.

Los jaguares (Panthera onca) y pumas (Puma concolor) se encuentran entre los principales depredadores tope de la Orinoquia. Desempeñan roles ecológicos fundamentales para el equilibrio de las sabanas nativas como la regulación de las poblaciones de herbívoros. El conflicto humano-felino en la cuenca del sitio Ramsar río Bita, Vichada-Colombia, se ha intensificado durante las últimas dos décadas. La presente investigación evalúa la efectividad de las medidas antidepredatorias implementadas en cinco producciones pecuarias entre febrero de 2018 y marzo de 2020. Encuestas estructuradas fueron aplicadas con la población que habita en los predios priorizados para documentar los eventos de depredación de animales domésticos por felinos antes y después de dos años de implementación de estas medidas. Se reportaron un total de 112 animales domésticos depredados por jaguares y pumas en todos los predios. El número de eventos de depredación entre el 2018 (n = 96; 86%) y 2020 (n = 16; 14%), se redujo en un 72% (n = 80 individuos). Los índices de uso de animales domésticos depredados por jaguares y pumas para cada predio establecen una preferencia hacia el ganado bovino (<36 meses de edad) a excepción del predio Witzara donde se evidenció la preferencia hacia los porcinos. La valoración económica de los animales domésticos depredados para el primer periodo evaluado en los cinco predios correspondió a 16.700 USD ($63.710.090) y posterior a la implementación de las medidas a 2.532 USD ($9.660.100). Una regresión múltiple no paramétrica y un modelo GAMLSS no evidenciaron la influencia de las variables explicativas (riqueza y abundancia de mamíferos presa de jaguares y pumas) sobre la variable dependiente (número de eventos de depredación en los predios). Las medidas antidepredatorias implementadas de manera integral fueron efectivas para mitigar el conflicto humano-felino en la cuenca del sitio Ramsar río Bita.
