Background/aim: It is recommended that a central venous catheter (CVC) be removed if central line-associated bloodstream infection (CLABSI) has been diagnosed. The objective of this retrospective study was to evaluate the risk factors for recurrent CLABSI in reinserted catheters in a pediatric intensive care unit. Materials and methods: Patients with recurrent and nonrecurrent CLABSI were compared in terms of the catheter exchange interval, the interval between negative blood culture and reinsertion of the CVC, and the pre-/reinsertion treatment duration...

INTRODUCTION: Arteriovenous graft (AVG) infection can result in life-threatening sepsis and loss of vascular access. A retrospective study was performed to establish an appropriate treatment strategy for AVG infection. METHODS: A total of 50 cases of AVG infection were treated between January 2005 and June 2016. The surgical methods used were total graft excision (TGE) (n = 34), or partial graft excision (PGE) with interposition graft (n = 16). RESULTS: Infection was noted at a puncture site (n = 22), a prior incision for surgery or endovascular therapy (n = 20), and abandoned (currently unused) grafts (n = 5)...

INTRODUCTION: All arteriovenous fistula/grafts options should be exhausted before haemodialysis is carried out via central venous catheters (CVC). CVCs carry high morbidity and mortality risks and in some patients, the central veins could be exhausted. In these patients, an arterioarterial prosthetic loop (AAPL) or straight graft can be the only option for haemodialysis. A systematic review was thus carried out to look at the use of arterioarterial graft for haemodialysis, with regards to dialysis adequacy, complications, and patency rates...

INTRODUCTION: With improved life expectancy and quality of life, elderly patients constitute a progressively larger fraction of consumers utilising renal replacement therapy (RRT). Although substantial data exist for younger cohorts, minimal evidence exists for outcomes of arteriovenous fistula (AVF) and central catheters (CVC) placed in those patients over 80 years. We examined outcomes of primary AVF placement in this cohort to ascertain durability and benefits of AVF in the over 80-year-old population...

OBJECTIVE: To review the ability of junior doctors (JDs) in identifying the correct anatomical site for central venous catheterization (CVC) and whether prior Advanced Trauma Life Support (ATLS) training influences this. DESIGN: We performed a prospective, observational study using a structured survey and asked a group of JDs (postgraduate year 1 [PGY1] or year 2 [PGY2]) to indicate on a photograph the exact site for CVC insertion via the internal jugular (IJV) and the subclavian (SCV) approach...

OBJECTIVES: Biofilm formation (BF) by fungal isolates may dramatically complicate infection. We determined the ability of C. parapsilosis isolates from single fungaemia episodes to form biofilms and we analysed biofilm subgroups for antifungal susceptibility and pathogenic potential. We then correlated BF with clinical characteristics and outcomes of the episodes. METHODS: BF was measured using the crystal-violet biomass assay, antifungal susceptibility of preformed biofilms was assessed, and virulence was studied using the Galleria mellonella model...

The aim of this study was to compare i) the physiological responses following cold-water immersion (CWI) and partial-body cryotherapy (PBC) and ii) the effects on recovery following a muscle-damaging protocol (5 x 20 drop jumps). Nineteen healthy males were randomly allocated into either a CWI (10 °C for 10 min; n = 9) or a PBC (-60 °C for 30 sec, -135 °C for 2 min; n = 10) group. The physiological variables (thigh muscle oxygen saturation [SmO2 ], cutaneous vascular conductance [CVC], mean-arterial pressure [MAP] and local skin temperature) were assessed immediately prior and up to 60 min post-treatment (10 min intervals)...

Peritoneal dialysis (PD) interruption requiring hemodialysis (HD) is not uncommon and its frequently abrupt nature prevents timely creation of permanent HD access and avoidance of central venous catheters (CVC). We retrospectively studied a cohort of 24 end-stage renal disease (ESRD) patients (mean age 50.7 years, 83.3% African-Americans, 58.3% females, time on dialysis interquartile range [IQR] 0 - 65 days) who had simultaneous PD catheter insertion and backup arteriovenous fistula (AVF) creation between January 1, 2012, and December 31, 2013...

Cardiovascular disease is the leading cause of mortality in Chronic Kidney Disease (CKD). Mitochondrial dysfunction secondary to CKD is a potential source of oxidative stress that may impair vascular function. This study sought to determine if mitochondria derived reactive oxygen species contribute to microvascular dysfunction in Stage 3-5 CKD. Cutaneous vasodilation in response to local heating was assessed in 20 CKD patients (60±13 years; eGFR 46±13ml/kg/1.73m2) and eleven matched healthy participants (58±2 years; eGFR>90ml/kg/1...

BACKGROUND: Adequate haemodialysis (HD) in people with end-stage kidney disease (ESKD) is reliant upon establishment of vascular access, which may consist of arteriovenous fistula, arteriovenous graft, or central venous catheters (CVC). Although discouraged due to high rates of infectious and thrombotic complications as well as technical issues that limit their life span, CVC have the significant advantage of being immediately usable and are the only means of vascular access in a significant number of patients...

The use of Central Venous Catheters (CVCs) commonly results in complications. Coatings with silver or metal alloys can reduce the risk associated with the use of CVC. We have evaluated the durability of a noble metal coated CVC (the Bactiguard Infectious Protection, BIP CVC) and compared with an uncoated CVC for clinical tolerability (Adverse Events, AEs) and performance, in order to create a baseline for a large future study. Patients undergoing major surgery, randomised at a 2:1 ratio to BIP CVC (n = 22) or standard CVC (n = 12), were catheterized 9 - 12 days, respectively...

Quasiparticle tunnel conductance-voltage characteristics (CVCs), $G(V)$, were calculated for break junctions (BJs) made up of layered $d$-wave superconductors partially gapped by charge-density waves (CDWs). The current is assumed to flow in the $ab$-plane of electrodes. The influence of CDWs is analyzed by comparing the resulting CVCs with CVCs calculated for BJs made up of pure $d$-wave superconductors with relevant parameters. The main CDW-effects were found to be the appearance of new CVC peculiarities and the lost of CVC symmetry with respect to the $V$-sign...

BACKGROUND: Ventriculo-atrial (VA) shunt is a routine technique for the treatment of hydrocephalus. Correct position at superior vena cava-right atrium junction is generally assessed by X-ray. We herein present the first experience of an alternative, non-radiographic technique to assess the distal end of the VA-shunts through an electrocardiographic (EKG) method. Such a technique is mutuated from the very large experience on central-venous catheters (CVC) worldwide: the EKG-guided method is a common and validated alternative to the standard radiological control of the location of the tip of any CVC...

INTRODUCTION: We determined if transcranial color-coded Doppler derived hemodynamics are associated with MRI based cerebral blood flow (CBF) in regions clinically important to dementia in healthy middle-aged adults. METHODS: In thirty subjects (18m/12f; age=52±1 years), blood flow velocity (BFV) and cerebrovascular conductance (CVC) were measured with transcranial color-coded Doppler (TCCD) at the middle cerebral artery (MCA) and cerebral blood flow (CBF) was assessed with arterial spin labeled perfusion MRI...

The increasing survival of hemodialysis patients results in the depletion of superficial venous capital justifying the use of the basilic vein. Many groups still prefer an arteriovenous graft due to transposition complexity and the time needed to achieve maturation. In this work we review the results of our series of basilic vein transpositions (BVT). BVTs were performed in two stages: first, creation of the fistula; second, transposition of the vein using three small incisions in the arm. All patients had to have direct arterialization of the basilic vein, therefore, patients with previous ipsilateral wrist fistulas also followed a two-stage protocol...

BACKGROUND: Poiseuille's law states flow rates are directly proportional to the radius to the 4th power and indirectly proportional to the length of a tube. Because of this property, large bore catheters are commonly used in the resuscitation of the critically ill patient. However, there are no studies comparing simultaneous use of all three lumens of a triple lumen (TL) central venous catheter (CVC) with other catheter types. Our objective was to compare the flow rates of normal saline (NS) through various resuscitation catheters against a TL CVC using all 3 ports...

In the last two decades, a growing body of theory and research has targeted the role of cardiac vagal control (CVC) in emotional responding. This research has either focused on resting CVC (also denoted as cardiac vagal tone) or phasic changes in CVC (also denoted as vagal reactivity) in response to affective stimuli. The present paper is aimed at reporting a review of the papers published between 1996 and 2016, and focused on the results of 135 papers examining cardiac vagal control as a physiological marker of emotion regulation in healthy adults...
