Redo surgical approach to the residual ventricular septal defect (VSD) is technically more demanding sternum re-entry has to be performed very carefully to avoid any uncontrolled bleeding and preparation of the adhesions has to be made to expose the most important structures (ascending aorta, caval veins). However, percutaneous transcatheter device closure of the residual VSD with radiation exposure can cause arrhythmia, valves injury and vascular complications. Herein we present a new and less invasive technique to treat residual VSD, without arterial access, radiation exposure and cardiopulmonary bypass. Aortic left ventricular tunnel (ALVT) is a rare, abnormal para-valvular communication between the aorta and the left ventricle1. ALVT can be associated with a variety of congenital heart diseases, but there are only a few reports of ALVT associated with bicuspid aortic valve (BAV)2,3. Linderalactone supplier There is no report of ALVT with BAV and aortic root aneurysm. Herein, we first report a 11-year-old boy who successfully underwent aortic valve-sparing root replacement (VSRR) for ALVT with BAV and aortic root aneurysm. BACKGROUND HVAD cannula position is associated with hemodynamics and heart failure readmissions. However, its impact on hemocompatibility-related adverse events (HRAEs) remains uncertain. METHODS HVAD patients were followed for one year following index hospitalization, when cannula coronal angle was quantified from chest X-ray. Invasive right heart catheterization and transthoracic echocardiography were performed. One-year occurrences of each HRAE were compared between those with and without a cannula coronal angle of >65 degrees. RESULTS Among 63 HVAD patients (median age 60 years, 63% male), 10 patients (16%) had cannula coronal angle >65 degrees. The wide-angle group had elevated intracardiac pressures and lower pulmonary artery pulsatility index (p 0.05). CONCLUSIONS HVAD cannula coronal angle was associated with reduced right ventricular function and HRAE. Prospective studies evaluating surgical techniques to ensure optimal device positioning and its effects on HRAEs are warranted. We propose a new approach of lymphadenectomy along bilateral recurrent laryngeal nerve (RLN) under mediastinoscopy through one left-neck incision. After established pneumomediastinum, esophagectomy begins to perform over the aortic arch to the level of lower edge of the left main bronchus, and the lymphadenectomy along the left RLN has also accomplished during this process. At the level of lower edge of the right subclavian artery (RSA), between the trachea and the esophagus, the instruments could get accessed to the right RLN. The lymphadenectomy could get accomplished up to 2-cm at the upper edge of the RSA. Idiopathic pneumonia syndrome (IPS) is a serious complication after hematopoietic stem cell transplantation (HSCT). Despite the high mortality rate with medical management, there have been no reported cases of lung transplants for IPS patients. Herein we report a case of 44-year-old woman developed IPS five months after HSCT for myelodysplastic syndrome. Despite aggressive medical management, the patient required intubation and was ultimately placed on extracorporeal membrane oxygenation awaiting recovery. However, her condition continued to deteriorate, and she subsequently underwent a double lung transplant with uneventful recovery. With the high mortality of medically-managed IPS, lung transplant could prove to be lifesaving. A 59-year-old man with a history of coarctation repair, mechanical aortic valve, and warfarin therapy presented with right flank pain. Computerized tomography (CT) scan showed a large hematoma encircling an intact descending thoracic aorta. CT angiogram demonstrated multiple areas of intercostal artery extravasation. Interventional radiology performed angiography and embolization. His course was complicated by an effusion and hypoxia; but no further bleeding was noted. We hypothesize coarctation association aneurysms and potential vessel wall weakness and as cause of hematoma in our case. We present the first case with history of repaired coarctation with multiple spontaneous intercostal artery aneurysmal rupture. BACKGROUND The integrase inhibitor dolutegravir is being considered in several countries in sub-Saharan Africa instead of efavirenz for people initiating antiretroviral therapy (ART) because of superior tolerability and a lower risk of resistance emergence. WHO requested updated modelling results for its 2019 Antiretroviral Guidelines update, which was restricted to the choice of dolutegravir or efavirenz in new ART initiators. In response to this request, we modelled the risks and benefits of alternative policies for initial first-line ART regimens. METHODS We updated an existing individual-based model of HIV transmission and progression in adults to consider information on the risk of neural tube defects in women taking dolutegravir at time of conception, as well as the effects of dolutegravir on weight gain. The model accounted for drug resistance in determining viral suppression, with consequences for clinical outcomes and mother-to-child transmission. We sampled distributions of parameters to create variyear for a country with an adult population size of 10 million. The policy involving ART initiation with a dolutegravir-based regimen in women intending pregnancy was cost-effective in 87% of our setting scenarios and this finding was robust in various sensitivity analyses, including around the potential negative effects of weight gain. INTERPRETATION In the context of a range of modelled setting scenarios in sub-Saharan Africa, we found that a policy of ART initiation with a dolutegravir-based regimen, including in women intending pregnancy, was predicted to bring population health benefits and be cost-effective, supporting WHO's strong recommendation for dolutegravir as a preferred drug for ART initiators. FUNDING Bill & Melinda Gates Foundation. Tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF) are both tenofovir (TFV) prodrugs, with the same active intracellular metabolite, TFV-diphosphate (TFV-DP). TAF delivers TFV-DP to target cells more efficiently and at lower doses than TDF, thereby substantially reducing systemic exposure to TFV, which results in improved bone and renal safety relative to TDF. As such, the method developed for the determination of TFV following TAF administration involved two key differences from determination of TFV following TDF administration. First, human plasma samples (500 μL) immediately upon collection were treated with 20% formic acid (40 μL) (plasma formic acid ratio of 1008) to minimize hydrolysis of TAF to TFV, and thereby avoided overestimation of TFV concentrations. Second, various TFV validation tests were conducted in the presence of TAF to mimic the high TAFTFV ratios in clinical samples collected within ~2 h after dosing. The method for determination of TFV was developed and validated at a US lab and followed FDA and EMA guidelines.
