e18261 Background: Multidisciplinary tumor board meetings have shown to improve quality and outcome in the care of cancer patients. Many tertiary centers conduct site specific tumor board meetings but not all the centers especially community oncology and international centers have the manpower capacity to hold site specific meetings, the overall impact of tumor boards on patients care may vary based on its structure and composition. We propose that institutional collaboration in the comprehensive care of cancer patients utilizing E-consult and E tumor board may help to improve patient care. Methods: Retrospective data of 134 patient cases seen at the American hospital Dubai between 2016-2018 was analyzed. Cases that were reviewed at the American Hospital multidisciplinary tumor board meeting (AHD-MDT) and also referred for second opinion utilizing Mayo e-consult/e-tumor board service were analyzed using electronic health record, AHD-MDT meeting minutes and reports of Mayo e-consult/e-tumor board. 3 major areas of case assessment for review were selected 1. Pathology . 2. Medical imaging. 3. Clinical recommendations. Variation in assessment and recommendations between AHD- MDT and Mayo Clinic were compared. Results: A total of 1018 cases were reviewed in the AHD-MDT between 2016 and 2018. 136 out of the 1018(13%) cases were referred for second opinion utilizing Mayo E-Consult or E-tumor board service. 117 cases were included in the analysis as there was missing data in 4 patients, 9 were duplicate and 4 were cancelled and 7 cases were not reviewed at AHD-MDT. In 78 cases pathology was reviewed at Mayo but 4 (5%) were not reviewed at AHD. In 74 (95%) cases, pathology was reviewed both at AHD and Mayo. There was change (Ch) in 2 (3%), 7(9%)updated(Ud) and no change(Ch) in 65 cases(88%). 97 cases of imaging had change(Ch) in 1 case (1%). 101 cases of e-consult/e-tumor board were assessed for clinical recommendations. There was change(Ch) in 3(3%), 2/3 cases had a change in plan due to change in the pathology. In 35(35%) the plan was updated (Ud) and 7 out of 35(20%) were due to updated(Ud) pathology. Conclusions: Our data indicates that international collaboration as part of MCCN has resulted in significant improvement in the patient care. In a select group of challenging cases, 35% had an improvement in the final treatment plan after utilization of e-consult/e-tumor board service.

Cardiovascular disease (CVD) is the most common cause of death worldwide. Cardiac rehabilitation (CR) is increasingly recognised as an essential part of clinical care for patients with CVD. CR is a complex intervention that encompasses a multidisciplinary approach that focuses on health education, modification of cardiovascular risk factors, exercise training, physical activity and stress management. In the current American Heart Association/American College of Cardiology guidelines, cardiac rehabilitation is a class IA recommendation for secondary prevention of acute myocardial infarction, percutaneous coronary intervention and cardiac surgery and Class II recommendation for chronic stable heart failure. Despite proven effectiveness, however, participation in traditional CR remains low. Although the reasons for participation and non-participation in CR have been well described, the use of Twitter to explore public perceptions of CR has not yet been formally reported. To the best of our knowledge, the analysis of Twitter for insights on CR is a novel investigation that is relevant for addressing significant problems related to CR awareness in the digital age. We performed data mining of Twitter to assess patients’ perceptions regarding CR and the reasons for their participation and non-participation in CR between 23 July 2015 and 22 October 2017. We analysed a total of 5515 Twitter messages. Tweets associated with CR were often used to self-report on health status either before or after participating in CR or contained emotional language with positive or negative comments, advertisements or updated news. Twitter users wrote mainly positive comments about CR, suggesting the platform has the potential to disseminate both the benefits of CR and its research to the public on the worldwide scale.

Acute myeloid leukemia (AML) is a complex disease with a variety of presentations. A large pericardial effusion is rare, occurring in less than 0.5% of all patients with AML prior to treatment. A 34-year-old male presented with dyspnea, malaise, and weight loss. On physical exam, he was noted to be hypoxic, tachypneic, tachycardic, and hypotensive. He had cervical lymphadenopathy and jugular venous distention. His WBC count was 110 bil/L with 33% blasts. Bone marrow biopsy confirmed AML with 60% blasts. Leukemic cells were also seen in the cerebrospinal fluid on lumbar puncture. An echocardiogram revealed a large pericardial effusion causing tamponade. He underwent emergent pericardiocentesis, and malignant cells were present in the pericardial fluid. Induction therapy with standard dose cytarabine and daunorubicin was initiated, and bone marrow biopsy 14 days later showed no residual AML. This case demonstrates the importance of a thorough evaluation of each organ system when caring for a patient with AML.

IntroductionDofetilide is a class III antiarrhythmic prescribed to cardiovert persistent atrial fibrillation (AF) to sinus rhythm (SR).HypothesisTo determine the clinical predictors of cardioversion and readmission in persistent AF patients on dofetilide.MethodsWe analyzed 160 patients with persistent AF who were started on dofetilide and followed for 1 year. We examined age, sex, race, hypertension, diabetes, smoking, dyslipidemia, CAD, left ventricular ejection fraction (LVEF), creatinine, BMI and concomitant use of calcium channel blockers (CCB), β‐blockers in a multivariable logistic regression model. We also examined the same predictors in Cox regression model for AF‐related readmission within 1 year of follow‐up.Results13.5% individuals did not convert to SR on dofetilide. 55.6% converted on the first dose and 83.1% converted by the fourth dose. In multivariable logistic models, dyslipidemia (OR: 2.4, CI: 1.12‐5.16) and LVEF (OR: 3.83,CI: 1.37‐10.8) were associated with failure to convert with the first dose. Female sex and LVEF also were associated with increased risk of failure to convert at all. Concomitant use of CCB associated with decreased risk of failure to convert to SR. In Cox proportional model, female sex, age <63 years and CAD were associated with increased AF readmission within 1 year.ConclusionsDyslipidemia and LVEF <40% were associated with failure to cardiovert after first dose, and female sex and LVEF 40% were related to failure to convert at all on dofetilide in persistent AF patients. After 1‐year follow‐up, female sex, known CAD, and age <63 years were associated with increased AF readmissions.
