COVID-19 and Renal Artery Thrombosis: A Case Report

Since the onset of the COVID-19 pandemic, there is increasing evidence that infected patients exhibit a high incidence of thrombotic complications. Although respiratory symptoms are dominant in COVID-19, those with the condition may have extrapulmonary involvement.

The Effectiveness of Adopting e-Learning during COVID-19 at Hashemite University

e-Learning is the utilization of the electronic technologies and the media to deliver the educational content to the learners, enabling them to interact actively with the content, the teachers, and their peers. Students’ interaction can be either synchronous or asynchronous or a combination of both. One advantage of the e-learning is that learners can access the educational content at any place and time saving them effort, time, and cost. To deal with the unprecedented crisis of COVID-19 and the risk of virus transmission in the public, the vast majority of higher learning institutions globally were locked out and the delivery of the educational content moved from the traditional classroom teaching to the internet. The purpose of this study was to assess students’ perceptions of the effectiveness of the e-learning during COVID-19 pandemic at the Hashemite University, Jordan. A total of 399 students completed the online survey of the study. Study results showed that students’ overall evaluation of their e-learning experiences were generally positive. However, students reported that they faced problems in the e-learning experiences of which most were related to technical issues (e.g., lack of a viable internet network, lack of laptops, etc.). Microsoft Teams was the platform most preferred by students for e-learning and the majority of students accessed the educational content using smart phones. Only gender and student’s academic specialty had significant associations with their perceptions of the effectiveness of the e-learning. © 2020, International Journal of Advanced Computer Science and Applications, All Rights Reserved

When Third Time's a Charm: Successful Outcome after Third Orthotopic Heart Transplantation

Introduction: Cardiac re-transplantation represents a small but growing proportion of total transplants being performed. Medical, ethical, moral and social dynamics continue to remain individualized and highly debated but more evolved with advancement in medicine for patients needing cardiac re-transplantation. We describe a case of a successful outcome in a patient requiring her third orthotopic heart transplant. Case: A 26 year old female with history of orthotopic heart transplant at age 11 for hypertrophic cardiomyopathy and subsequent re-transplantation for cardiac allograft vasculopathy (CAV) ten years later presented to our emergency room with cardiac arrest. Prior to the index hospitalization, the patient had an echocardiogram with a mildly reduced ejection fraction and an angiogram with chronic total occlusions of the right coronary artery and left circumflex artery with excellent collaterals and preserved cardiac output. Nuclear stress test showed no evidence of ischemia. Cardiac allograft vasculopathy prophylaxis with aspirin and pravastatin in addition to a triple regimen of immunosuppression of tacrolimus, sirolimus and mycophenolate mofetil were verified. The hospitalization was complicated by rapidly deteriorating biventricular function and three more episodes of cardiac arrest ultimately requiring extracorporeal membrane oxygenation (ECMO). Fortunately, the patient had negative HLAs with 0% CPRA and preserved end organ function. The selection committee thoughtfully considered her history of intermittent social marijuana use, active COVID 19 precautions in the hospital and a third sternotomy at such a young age, with likely need of possible 4th heart transplant in the future, but ultimately approved the patient for listing. Despite being Status 1, the patient had near daily loss of pulsatility for greater than 10-15 minutes which made us consider the possibility of total artificial heart. Fortunately, the patient received a local heart due to the COVID travel restrictions with total ischemic time of 98 minutes. She was induced with basiliximab and had negative retrospective and prospective crossmatches. There were no intra-op complications and post-op the patient had mild RV dysfunction requiring 4 days of inotropes. Patient was successfully discharged 9 days following her third OHT. Conclusion: Patients undergoing re-transplantation have overall poorer outcomes than those undergoing primary transplantation. Several factors influence these outcomes including timing from prior transplant, previous sternotomy, sensitization status, and renal dysfunction. With advances in medicine and pediatric patients living well into adulthood, there will be more patients requiring re-transplantation. As these trends emerge, individualized patient selection remains the key factor to improved outcomes. Our case presents an otherwise healthy young woman with graft failure without evidence of sensitization who underwent a successful third transplantation.
