The amount and evolutionary impact of horizontal gene transfer in eukaryotes remain contentious issues. A new phylogenomic study suggests that gene transfer from prokaryotes has contributed significantly to the adaptation and metabolic evolution of Blastocystis, the most widespread human gut eukaryotic parasite.

Peripheral arterio-venous malformations (pAVMs) are congenital vascular anomalies that require treatment, due to their severe clinical consequences. The complexity of lesions often leads to misdiagnosis and ill-planned treatments. To improve disease management, we developed a computational model to quantify the hemodynamic effects of key angioarchitectural features of pAVMs. Hemodynamic results were used to predict the transport of contrast agent (CA), which allowed us to compare our findings to digital subtraction angiography (DSA) recordings of patients...

OBJECTIVES: To evaluate the safety and feasibility of subclavian artery stenting for coronary-subclavian steal syndrome (CSSS). BACKGROUND: CSSS is a rare cause of myocardial ischemia due to ipsilateral subclavian artery stenosis in patients who have undergone coronary artery bypass graft. However, current knowledge of the optimal therapy for CSSS is limited. METHODS: The clinical data of 37 patients (33 male; mean age 65 ± 6 years) with CSSS who had undergone subclavian artery stenting between April 2007 and December 2015 were analyzed...

Forearm and upper arm arteriovenous grafts perform similarly in terms of patency and complications. Primary patency at 1 year for forearm arteriovenous grafts versus upper arm grafts ranges from 22%-50% versus 22%-42%, and secondary patency at 1 year ranges from 78%-89% versus 52%-67%), respectively. Secondary patency at 2 years, ranges from 30%-64% versus 35%-60% for forearm and upper arteriovenous graft, respectively. Ample pre-operative planning is essential to improved clinical success and the decision to place a graft at one location versus the other should be based solely on previous access history, physical exam, appropriate venous imaging, and other factors that make up the clinical picture...

INTRODUCTION: In this article, we will review the clinical symptoms of dialysis access steal syndrome (DASS), evaluation, treatment options, and our approach and treatment algorithm. METHODS: We reviewed the literature discussing different aspects of DASS including its epidemiology, pathogenesis, clinical presentation, evaluation and management options. RESULTS: DASS is the most dreaded complication of access surgery. Although the incidence is low, all providers caring for dialysis patients should be aware of this problem...

OBJECTIVE: Angiographically detectable Thebesian veins (ThVs) are a rare finding sometimes associated with coronary steal and myocardial ischemia in adults, but there are limited data regarding prominent ThVs in the setting of complex congenital heart disease (CHD). This study represents the largest series to date describing the presence and temporal changes of angiographically detectable ThVs in children with CHD. METHODS: This is a single center case series describing the clinical characteristics and coronary anatomy in children with CHD and angiographicall detectable ThVs...

Background An N-butyl-2 cyanoacrylate (NBCA) embolus in the graft portal vein was frequently observed after an intraoperative embolization of portosystemic collaterals performed to prevent portal steal in liver transplant (LT) recipients. The radiological and clinical features of NBCA emboli have not yet been described. Purpose To describe radiological and clinical features of NBCA embolus in graft portal vein after portosystemic collateral embolization in LT recipients. Material and Methods A total of 165 consecutive LT recipients who had undergone intraoperative NBCA embolization of varix were found in single institution's computerized databases of a clinical cohort of LT...

PURPOSE: This study was designed to evaluate the long-term patency rate and complications associated with early use of the autogenous forearm arteriovenous fistula (AFAVF) in patients needing urgent hemodialysis. METHODS: The clinical data of all patients undergoing AFAVFs for hemodialysis access between June 1996 and June 2016 were retrospectively evaluated. The primary and secondary patencies were estimated using the life table method. RESULTS: A total of 104 AFAVFs were created for 102 patients...

BACKGROUND: Splenic steal syndrome (SSS) is a condition that can occur after orthotopic liver transplant (OLT). However, limited information is available about this condition. METHODS: A systematic literature search of studies performed through May 2016 was conducted to identify reports of angiographically confirmed SSS and its variants. All of the factors relevant to this disorder were collected and analyzed. RESULTS: A total of 219 cases of SSS and its variants were identified...

Atherosclerosis affecting the carotid arteries accounts for up to 20% of ischemic strokes 1. The clinical effects of atherosclerotic occlusive disease vary according to multiple factors, one of which is collateral circulation. In response to a chronic decrease in cerebral perfusion from atherosclerotic occlusion, alternative flow pathways, or collaterals, develop in a variety of patterns. In the setting of carotid occlusion, flow from the Circle of Willis, if complete, often comprises the main cerebral collateral network...

Moyamoya disease is characterized by bilateral progressive terminal internal carotid arteries steno-occlusion. In this patient, the disease affected middle cerebral arteries and was disclosed after a left frontal cerebral infarction. Brain HMPAO perfusion scintigraphy with acetazolamide challenge, obtained before surgical treatment, demonstrates an extended bilateral frontal hypoperfusion with a vascular steal phenomenon. The same examination obtained after surgical treatment demonstrates a frank improvement in basal brain vascularization, with nearly complete correction of vascular steal phenomenon...

Deciphering the direction of information flow is critical to understand the brain. Data from non-human primate histology shows that connections between lower to higher areas (e.g. retina→V1), and between higher to lower areas (e.g. V1←V2) can be dissociated based upon the distribution of afferent synapses at the laminar level. Ultra-high field scanners opened up the possibility to image brain structure and function at an unprecedented level of detail. Taking advantage of the increased spatial resolution available, it could theoretically be possible to disentangle activity from different cortical depths from human cerebral cortex, separately studying different compartments across depth...

OBJECTIVE: We assessed prevalence of suicidal ideation and plans among illicit drug users and their association with contextual factors, by gender. METHODS: Cross-sectional study. In a sample of 511 illicit drug users recruited during spring 2012 in drug treatment and prevention facilities in Catalonia (Spain), the prevalence of suicidal ideation/plans in the last 12 months was assessed. Poisson regression was used to examine associations between suicidal ideation/plans and various factors (socio-demographic, psychological, illegal drug market activities and marginal income generation activities, which included any reported sex work, stealing, peddling, begging or borrowing on credit from a dealer)...

PURPOSE: The Flixene™ (Atrium™, Hudson, NH) is a trilaminate composite polytetrafluoroethylene (PTFE) graft that allows access within 72 hours. We evaluate our initial experience with this device for conventional and complex hemodialysis access creation. METHODS: Retrospective review in end-stage renal disease (ESRD) patients who underwent access creation with Flixene from January 2013 to July 2014. For our analysis, the patients were divided in two groups: those with complex access configurations tunneled in the chest and/or abdominal wall (thoraco-abdominal wall access [TAWA]), and those tunneled in conventional sites (extremity access [EA])...

BACKGROUND: The United States has by far the highest rates of homicide perpetration among high-income countries. The perpetration of homicide by children is often newsworthy, but little is known about the incidence or the circumstances of child homicide perpetration. METHODS: We use data from the sixteen states reporting to the National Violent Death Reporting System (NVDRS) for all years 2005-2012. We read every violent death report that was classified a homicide with a child suspect (aged 0-14)...
