BACKGROUND: In patients with left ventricular heart failure (HF), the development of pulmonary hypertension (PH) is common and represents a strong predictor of death. Despite recent advances in the pathophysiological understanding there is as yet no prospect of cure of this deadly clinical entity and the majority of patients continue to progress to right ventricular failure and die. Furthermore, there is no single medical treatment currently approved for PH related to HF. There is, therefore an urgent unmet need to identify novel pharmacological agents that will prevent the progressive increased or reverse the elevated pulmonary arterial pressures while enhancing cardiac performance in HF...

BACKGROUND: The impact of catheter-associated urinary tract infections (CAUTIs) on immunocompromised patients with cancer requires preventive intervention from bedside nurses.
. OBJECTIVES: This protocol aims to prevent CAUTIs in the inpatient oncology population by implementing an evidence-based, nurse-driven protocol for discontinuing indwelling urinary catheters (IUCs).
. METHODS: Following a literature review of 34 articles, a nurse-driven CAUTI prevention protocol was developed and implemented on two 26-bed oncology units...

OBJECTIVES: Mortality associated with the modified Blalock-Taussig shunt (MBTS) remains high despite advanced perioperative management. This study was formulated to provide data on (1) current indications, (2) outcomes, and (3) factors affecting mortality and morbidity. DESIGN: A retrospective single center chart review identified 95 children (excluding hypoplastic left heart lesions) requiring a MBTS. Mortality and major morbidity were analyzed using the Kaplan Meier method and risk factor analysis using Cox's proportional hazard regression...

Aaron C Chan, Young-Joo Hong, Shuichi Makita, Masahiro Miura, Yoshiaki Yasuno
We propose using maximum a-posteriori (MAP) estimation to improve the image signal-to-noise ratio (SNR) in polarization diversity (PD) optical coherence tomography. PD-detection removes polarization artifacts, which are common when imaging highly birefringent tissue or when using a flexible fiber catheter. However, dividing the probe power to two polarization detection channels inevitably reduces the SNR. Applying MAP estimation to PD-OCT allows for the removal of polarization artifacts while maintaining and improving image SNR...

BACKGROUND/AIMS: Left ventricular hypertrophy and dysfunction are key cardiovascular risk factors of patients on peritoneal dialysis (PD). The purpose of this study was to investigate the dynamic changes of left ventricular (LV) structure and function in patients on long-term PD. METHODS: Patients who underwent PD catheter insertions from January 2010 to December 2012 in our PD center were enrolled into this study. Cardiac structure and function of those patients were determined by echocardiography (4 times) at 12-month intervals...

REVIEW
Scott J Millington, Seth Koenig
Procedures designed to drain fluid or air from the pleural spaces can be technically challenging in patients who are critically ill, and are associated with significant complications. Many individual ultrasound techniques have been described, each with the goal of making pleural drainage procedures safer. This article presents a systemic approach for incorporating many of these tools into procedures such as diagnostic thoracentesis, therapeutic drainage, or pleural catheter insertion. A series of illustrative figures and narrated video presentations are included to demonstrate many of the described techniques...

BACKGROUND: The prevalence of carbapenem-resistant Enterobacteriaceae (CRE) has been reported to be lower in Japan than in many other countries. However, extensive surveillance for CRE carriage has not been performed in Japan. AIM: To investigate the prevalence of CRE carriage in Japan among convalescent patients considered to be at high-risk of being CRE carriers using an improved selective culture medium. METHODS: A cross-sectional survey was conducted in 22 acute care hospitals (ACHs) and 21 long-term care hospitals (LTCHs) in northern Osaka from December 2015 to January 2016...

REVIEW
Oleg Pikovsky, Anat Rabinovich
Post-thrombotic syndrome (PTS) is a complication that develops in up to 50% of patients with deep vein thrombosis (DVT) and manifests as symptoms and signs of chronic venous insufficiency of varying severity. PTS negatively affects patient's quality of life and causes significant burden to the healthcare system. The risk for PTS development can be markedly reduced by preventing DVT and providing appropriate anticoagulation once it develops. Patients with extensive proximal (iliofemoral) DVT may benefit from invasive interventions, such as catheter-directed thrombolysis...

BACKGROUND: Arterial lactate (aLact) has been widely used to guide therapeutic decisions in children with shock. We evaluated the feasibility of central venous lactate (cvLact) in assessing aLact among children with shock. METHODS: Pairs of arterial and central venous samples for lactate concentrations were collected simultaneously during the shock and hemodynamically stable states. The results were analyzed by using a Cobas 8000 analyzer. RESULTS: Sixty-four blood paired samples were collected from 48 patients...

OBJECTIVE: Unfamiliarity of endovascular surgeons with carbon dioxide (CO2) angiography is one of the main reasons for its limited use. This review is intended to familiarize the reader with the principles and applications of that modality. METHODS: We conducted a comprehensive review of contemporary literature related to CO2 angiography and its use in the field of vascular and endovascular surgery, including technical details and diagnostic and interventional applications...

BACKGROUND: We present a case series of upper extremity fibromuscular dysplasia (UE FMD) consisting of 22 patients from two tertiary referral centers focusing on clinical presentation, diagnostic findings, and interventional outcomes. FMD is a noninflammatory, nonatherosclerotic arteriopathy that has a predisposition for middle-aged women. Involvement of the UE is thought to be rare. Patients with UE FMD can present with claudication or ischemia, or they can be incidentally diagnosed...

Four children (3 boys and 1 girl, age 1.4-9.4 y) presented 2-70 months after liver transplantation (mean 26 months) with high-grade narrowing at the surgical anastomosis that could not be crossed at percutaneous transhepatic cholangiography. Each patient was treated with a combined surgical and interventional radiology "rendezvous" procedure. Biliary drainage catheters were left in place for an average of 6 months after the procedure. At a mean 7.5 months after biliary drainage catheter removal, all children were catheter-free without clinical or biochemical evidence of biliary stricture recurrence...

A 5-year-old boy with midaortic syndrome who had undergone aortic bypass and bilateral renal artery grafts presented to the emergency department 1 year after surgery with symptoms of nausea, vomiting, and abdominal pain. Because of delay in diagnosis of bilateral renal artery thrombosis, his condition progressed to anuric renal failure. He underwent catheter-directed thrombolysis 7 days after presentation with administration of tissue plasminogen activator and heparin infusion over a 24-hour period. There was successful resolution of thrombus and complete recovery of renal function to baseline...

OBJECTIVE: To evaluate safety and feasibility in a first in human trial of direct MRI-guided prostate biopsy using a novel robotic device. METHODS: MrBot is an MRI-safe robotic device constructed entirely of nonconductive, nonmetallic, and nonmagnetic materials, developed by our group. A safety and feasibility clinical trial was designed to assess the safety and feasibility of direct MRI-guided biopsy with MrBot and determine its targeting accuracy. Men with elevated PSA, prior negative prostate biopsy and cancer suspicious region (CSR) on MRI were enrolled in the study...

BACKGROUND: While the body of evidence showing the benefit of contact force (CF) sensing catheters in improving AF ablation success rate is growing, real-world safety data of this technology are limited. OBJECTIVE: The aim of this study is to report the complication rate in patients undergoing ablation using one specific CF sensing catheter (TactiCath™Quartz Contact Force Ablation Catheter (Abbott, St Paul, MN)) in a large worldwide database. METHODS: - User-reported adverse event data from January 2014 - December 2015 was reviewed for the ablation catheter...
