OBJECTIVE: Endovenous thermal ablation in the form of radiofrequency ablation (RFA) or endovenous laser ablation (EVLA) has quickly ascended to a prime position in the treatment of venous insufficiency. While there is good data examining the rates of thrombotic complications, there is a relative paucity of data examining the recanalization rates after endovenous thermal ablation (ETA). METHODS: Data analysis was performed for 1475 thermal ablations in 485 patients from 2012-2015 as a retrospective chart review...

OBJECTIVE: Iliac vein stenting is increasingly being used in the treatment of venous insufficiency for patients with nonthrombotic iliac vein lesions (NIVL). We have noticed that many stents do not deploy to the expected stent area as designated by the manufactured diameter. The purpose of this study was to evaluate the dynamics of Wallstent® expansion in the iliocaval system. METHODS: Retrospective analysis of all patients with NIVL who were treated with iliac vein stenting using Wallstents®...

Interleukin 6 (IL6) is an inflammatory cytokine; signaling via its receptor (IL6R) is believed to contribute to development of inflammatory bowel diseases (IBD). The single nucleotide polymorphism rs2228145 in IL6R associates with increased levels of soluble IL6R (s-IL6R), as well as reduced IL6R signaling and risk of inflammatory disorders; its effects are similar to those of a therapeutic monoclonal antibody that blocks IL6R signaling. We used the effect of rs2228145 on s-IL6R level as an indirect marker to investigate whether reduced IL6R signaling associates with risk of ulcerative colitis (UC) or Crohn's disease (CD)...

BACKGROUND: In low and middle-income countries, reliable data on the epidemiology of childhood acute kidney injury (AKI) is lacking. The Global Snapshot, conducted by the ISN "0by25" AKI initiative, was a world-wide cross-sectional, observational study to evaluate AKI in hospitalized patients. Here we report the pediatric results of this study. PATIENTS AND METHODS: We prospectively collected data on children who met the Kidney Disease Improving Global Outcomes AKI criteria during a 10-week window in late 2014...

Hematopoietic cell transplantation (HCT) is a common treatment for many disorders. Albuminuria post-HCT, which may represent endothelial injury or inflammation from graft vs. host disease, increases the risk of chronic kidney disease and non-relapse mortality at 1 year. HCT patients also have abnormal blood pressure (BP) and increased rates of cardiovascular complications. We sought to determine the relationships between albuminuria, endothelial dysfunction and BP in HCT patients. Patients ≥ 12 years of age who had their first allogeneic HCT between 2012-2015 and survived through day 80 were eligible...

OBJECTIVE: Radiofrequency ablation (RFA) is increasingly being employed for treatment of perforator vein insufficiency and venous ulcer healing. Previous studies have shown a closure rate of 60% to 80% in incompetent perforator veins (IPVs) with RFA. The purpose of the study was to determine the utility of a redo RFA for symptomatic recanalized perforators and to predict factors associated with recanalization. METHODS: A retrospective analysis of 642 procedures in 256 patients with venous insufficiency due to IPVs from 2009 to 2015 was conducted...

BACKGROUND AND OBJECTIVES: Kidney injury is a significant complication for patients undergoing hematopoietic cell transplantation (HCT), but few studies have prospectively examined changes in GFR in long-term survivors of HCT. We described the association between changes in GFR and all-cause mortality in patients up to 10 years after HCT. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a prospective, observational cohort study of adult patients undergoing HCT at the Fred Hutchinson Cancer Center in Seattle, Washington from 2003 to 2015...

Infantile choriocarcinoma (ICC) is a rare, highly malignant form of gestational trophoblastic neoplasia. Rapid diagnosis and initiation of treatment are paramount in reaching a successful outcome. Patients with these tumors typically present with a triad of anemia, hepatomegaly, and precocious puberty. Cutaneous manifestations of ICC are extraordinarily rare with few documented cases. Here, we describe a male neonate who presented to our Dermatology clinic with a rapidly growing, markedly vascular glabellar mass associated with abnormal laboratory values suggestive of Kasabach-Merritt phenomenon...

OBJECTIVE: It has been a widely accepted practice that a previous placed pacemaker, automatic implantable cardioverter defibrillators, or central line can be a contraindication to placing a hemodialysis catheter in the ipsilateral jugular vein. Fear of dislodging pacing wires, tunneling close to the battery site or causing venous obstruction has been a concern for surgeons and interventionalists alike. We suggest that this phobia may be unfounded. METHODS: A retrospective review was conducted of patients in whom hemodialysis catheters were placed over a period of 10 years...

BACKGROUND: We hypothesized that there may be significant differences between academic productivity of the vascular training programs in the United States (US) and Europe. In an effort to explore this theory, we reviewed the number of vascular publications listed in PubMed from 2010 to 2015 for US and European directors in vascular surgery. METHODS: The list of program directors from the Association of Program Directors in Vascular Surgery (APDVS) and the European Union of Medical Specialists (EUMS) were queried for the names of the directors of vascular surgical training programs at the end of 2015...

Background There have been well-documented implications of race/ethnicity on the outcome of various vascular diseases, yet there are limited data on risk factors and outcome of lower limb swelling. While many patients improve with endovenous therapy (thermal ablation or iliac vein stenting), some patients' symptoms persist. The goal of this study was to identify clinical factors including race/ethnicity related to persistent leg swelling after treatment with both iliac vein stenting and thermal ablation. Methods From February 2012 to February 2014, this observational study analyzed data for 173 patients with chronic venous insufficiency who underwent both iliac vein stent placement as well as thermal ablation (radiofrequency ablation or endovenous laser ablation)...

Bo Song, Samir M Hamdan, Manju M Hingorani
Flap endonucleases catalyze cleavage of single-stranded DNA flaps formed during replication, repair, and recombination and are therefore essential for genome processing and stability. Recent crystal structures of DNA-bound human flap endonuclease (hFEN1) offer new insights into how conformational changes in the DNA and hFEN1 may facilitate the reaction mechanism. For example, previous biochemical studies of DNA conformation performed under non-catalytic conditions with Ca2+ have suggested that base unpairing at the 5'-flap:template junction is an important step in the reaction, but the new structural data suggest otherwise...

RNA-DNA hybrid primers synthesized by low fidelity DNA polymerase α to initiate eukaryotic lagging strand synthesis must be removed efficiently during Okazaki fragment (OF) maturation to complete DNA replication. In this process, each OF primer is displaced and the resulting 5'-single-stranded flap is cleaved by structure-specific 5'-nucleases, mainly Flap Endonuclease 1 (FEN1), to generate a ligatable nick. At least two models have been proposed to describe primer removal, namely short- and long-flap pathways that involve FEN1 or FEN1 along with Replication Protein A (RPA) and Dna2 helicase/nuclease, respectively...

The management of elderly patients with glioblastoma-multiforme (GBM) remains poorly defined with many experts in the past advocating best supportive care, in view of limited evidence on efficacy of more aggressive treatment protocols. There is randomised evidence (NORDIC and NA-O8 studies) to support the use of surgery followed by adjuvant monotherapy with either radiotherapy (RT) using hypofractionated regimes (e.g. 36 Gy in 6 fractions OR 40 Gy in 15 fractions) or chemotherapy with temozolomide (TMZ) in patients expressing methylation of promoter for O6 -methylguanine-DNA methyltransferase enzyme...

BACKGROUND: Evidence largely from animal studies suggests that conjugated linoleic acid (CLA) may have cardiovascular health benefits. However, few prospective studies have examined the association between CLA and cardiovascular disease. We have prospectively examined the association between serum CLA and incident coronary heart disease and heart failure (HF) in older men. METHODS AND RESULTS: Prospective study of 3806 men, aged 60 to 79 years, without prevalent HF followed up for an average of 13 years, during which there were 295 incident HF cases...
