Existing literature suggests that use of telemedicine during postoperative appointments can increase access to care and is valued by patients and providers alike. While research examining the clinical equivalency of telemedicine visits for postoperative care has been growing, few studies have reported on telemedicine follow-up after neurosurgery. This study examined if a videoconferencing visit could substitute for an in-person clinic visit for elective neurosurgical cases in the USA. This was a single-center prospective study of patients who underwent elective neurosurgical procedures (aneurysm clipping, resection of cavernous angiomas, resection of arterial venous malformation, microvascular decompression for trigeminal neuralgia and hemifacial spasm, and certain benign brain tumors) and were offered telemedicine follow-up care by an allied health professional during the first 90 days after neurosurgery...

Coronary artery disease is one of the leading causes of death worldwide. The stenotic coronary vessels are generally treated with coronary artery bypass grafts (CABGs), which can be either arterial (internal mammary artery, radial artery) or venous (saphenous vein). However, the different mechanical properties of the graft can influence the outcome of the procedure in terms of risk of restenosis and subsequent graft failure. In this paper, we perform a computational fluid-structure interaction (FSI) analysis of patient-specific multiple CABGs (Y-grafts) with the aim of better understanding the influence of the choice of bypass (arterial vs venous) on the risk of graft failure...

BACKGROUND & AIMS: Patients with hepatitis C virus (HCV)-associated cirrhosis and clinical significant portal hypertension (CSPH, hepatic venous pressure gradient [HVPG] 10 mmHg or greater), despite achieving sustained virological response (SVR) to therapy, remain at risk of liver decompensation. We investigated hemodynamic changes following SVR in patients with CSPH and whether liver stiffness measurements (LSMs) can rule out the presence of CSPH. METHODS: We performed a multicenter prospective study of 226 patients with HCV-associated cirrhosis and CSPH who had SVR to interferon-free therapy at 6 Liver Units in Spain...

Male premature neonates are more susceptible than females to the development of bronchopulmonary dysplasia (BPD). The reasons underlying sexually dimorphic outcomes in premature neonates are not known. GDF15 (Growth and differentiation factor 15) is a secreted cytokine and plays a role in cell proliferation, apoptosis, and angiogenesis. In this study, we sought to elucidate the sex-specific expression of Gdf15 in the lung in vivo in neonatal hyperoxic lung injury and its regulation by Hif-1α, and to delineate the differences in GDF15 expression in male and female human umbilical venous endothelial cells in an in vitro model of oxygen toxicity...

BACKGROUND: Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis, is a serious complication after total joint arthroplasty (TJA). Risk assessment models are increasingly used to provide patient-specific risk stratification. A recently implemented protocol mandates calculation of a Caprini Score for all surgical patients at our institution. We investigated the accuracy of the Caprini Score in predicting VTE events following TJA. METHODS: A retrospective review of patients undergoing primary total hip (THA) and total knee arthroplasty (TKA) over a 1-year time period was performed...

Pacemaker-induced superior vena cava syndrome (SVCS) is a rare but incapacitating adverse event that can occur years after implantation. Inasmuch as it is a rare disease, there is no consensus about its treatment. The most widely used option is balloon angioplasty and venous stent implantation, with preservation of the lead or previous extraction and subsequent reimplantation after the procedure, which is associated with new episodes of thrombosis. The epicardial implantation reduces the risk of thrombosis...

BACKGROUND: The efficacy of cold in situ perfusion and static storage of the liver is one possible determinant of transplantation outcomes. The aim of this study was to determine whether there is evidence to substantiate a preference for a particular perfusion route (aortic or dual) or perfusion/preservation solution in donation after brain-death (DBD) liver transplantation. METHODS: The Embase, Medline and Cochrane databases were utilized (1980-2017). Random effects modeling was used to estimate effects on transplantation outcomes based upon (i) aortic or dual in situ perfusion, and (ii) the use of University of Wisconsin (UW), histidine-tryptophan-ketoglutarate (HTK), Celsior and/or Institut Georges Lopez-1 (IGL-1) for perfusion/preservation...

BACKGROUND Platelet-rich plasma (PRP) has gained growing popularity in use in spinal fusion procedures in the last decade. Substantial intraoperative blood loss is frequently accompanied with spinal fusion, and it is unknown whether blood harvested intraoperatively qualifies for PRP preparation. MATERIAL AND METHODS Whole blood was harvested intraoperatively and venous blood was collected by venipuncture. Then, we investigated the platelet concentrations in whole blood and PRP, the concentration of growth factors in PRP, and the effects of PRP on the proliferation and viability of human bone marrow-derived mesenchymal stem cells (HBMSCs)...

AIMS: Deciding if a diabetic foot ulcer is infected in a community setting is challenging without validated point-of-care tests. Four inflammatory biomarkers were investigated to develop a composite algorithm for mildly infected diabetic foot ulcers: venous white cell count, C-reactive protein (CRP) and procalcitonin, and a novel wound exudate calprotectin assay. Calprotectin is a marker of neutrophilic inflammation. METHODS: In a prospective study, people with uninfected or mildly infected diabetic foot ulcers who had not received oral antibiotics in the preceding 2 weeks were recruited from community podiatry clinics for measurement of inflammatory biomarkers...

This report describes a novel approach of accessing the superficial veins of the upper extremity for the treatment of pulmonary emboli (PE) with an ultrasound enhanced thrombolytic infusion catheter. In a patient suffering from saddle PE and impending right heart failure, separate basilic and cephalic venous access sites in the right arm were utilized to insert EKOS EndoWave Infusion Catheter (EKOS Corporation, Bothell, WA) insertion in each pulmonary artery (PA). This technique could be advantageous, particularly for patients at high risk for access site complications and those unable to lie supine for prolonged duration of infusion therapy...

Cardiac resynchronization therapy has emerged as the gold standard for heart failure patients with left ventricular systolic dysfunction and electrical dyssynchrony from an intrinsic intraventricular conduction delay or right ventricular pacing. However, the limits imposed by the coronary sinus venous anatomy restrict the applicability of the technology for many potential recipients. Furthermore, conventional resynchronization, by virtue of utilizing a single site of epicardial origin for left ventricular activation, is non-physiological...
