REVIEW
Hedaya Hina, Joan McDowell
AIM: To investigate the procedural aspects in inserting central venous catheters that minimise central line associated bloodstream infections rates in adult intensive care units through a structured literature review. BACKGROUND: In adult intensive care units (AICU), central line associated bloodstream infections (CLABSI) are a major cause of high mortality rates and increased in costs due to the consequences of complications. METHODS: Eligible articles were identified by combining indexed keywords using Boolean operator of "AND" under databases of Ovid and CINAHL...

Coronary artery calcification (CAC), cardiac valve calcification (CVC) and left ventricular hypertrophy (LVH) are frequently observed in chronic kidney disease (CKD) patients. These abnormalities significantly affect morbidity and mortality. The aim of this study was to investigate the relationship between CAC, CVC and LVH in CKD patients. This study included 96 patients who were hospitalized and initiated hemodialysis between December 2011 and July 2014 at our five institutions. Multi-detector computed tomography for the quantification of CAC using the Agatston score and transthoracic echocardiography for assessing CVC and LVH were performed for all patients included in the study...

PURPOSE OF REVIEW: Central venous catheters (CVCs) have a prominent role in the diagnostic and therapy of neonates and children. Herein, we describe the multiple indications for CVC use and the different devices available for central venous access. Given the prevalent use of CVCs, healthcare systems are focused on reducing complications from their use, particularly central line-associated bloodstream infections (CLABSIs). The most up-to-date information available sheds light on best practices and future areas of investigation...

BACKGROUND: Apheresis treatments can be performed with peripheral venous catheters (PVC), although central venous catheters (CVC) are inserted when PVCs fail or patient with history of difficult vascular access prior to the apheresis. Ultrasound guidance for PVC has shown promising results in other settings. PURPOSE: To investigate if ultrasound guidance for PVC could be implemented among apheresis nurses. Second, how implementation of ultrasound guidance affected the number of CVCs used for apheresis per patient...

ABSTRACTHemodialysis (HD) and peritoneal dialysis (PD) represent two complementary modalities of renal replacement therapy (RRT) for end-stage renal disease patients. Conversion between the two modalities is frequent and more likely to happen from PD to HD. Every year, 10% of PD patients convert to HD, suggesting the need for recommendations on how to proceed with the creation of a vascular access in these patients. Criteria for selecting patients who would likely fail PD, and therefore take advantage of a backup access, are undefined...

Many guidelines recommend that end-stage renal disease (ESRD) patients should have a permanent vascular access, preferably an autologous arteriovenous fistula (AVF), at the start of renal replacement therapy. Nevertheless, a large proportion of patients still start hemodialysis with a central venous catheter (CVC). On the other hand, there are increasing numbers of patients in whom an AVF has been created, but who never actually end up on dialysis, as well as a substantial number of patients in whom creation of a vascular access has been attempted unsuccessfully...

Arteriovenous fistulas (AVF) improve survival and morbidity for most haemodialysis (HD) patients. Are they better for all patients? In the enthusiastic pursuit of AVFs for all, concerns have been raised regarding high primary AVF failure rates, continued high incident central venous catheter (CVC) use in some countries, and the limited life expectancy of some HD patients. "Fistula first" is changing to "catheter last". The focus must be on decreasing AVF failure to mature and decreasing incident CVC use. An optimal outcome should be sought for each individual patient, and multiple failed attempts at AVF creation avoided...

Noradrenaline is responsible for eliciting ∼60% of the reflex cutaneous vasoconstriction (VC) response in young adults, whereas the remainder is due to one or more unidentified coreleased sympathetic adrenergic neurotransmitter(s). Inconsistent evidence has placed neuropeptide Y in this role; however, other putative cotransmitters have yet to be tested. We hypothesize that ATP contributes to the reflex cutaneous VC response. Two protocols were conducted in young adults (n = 10); both involved the placement of three microdialysis (MD) probes in forearm skin and whole-body cooling (Tsk  = 30...

PURPOSE: We hypothesized that skin blood flow (SBF) of fingers are modulated during concentrated finger perception and that the changes in SBF reflect fluctuations in finger volume (FV). The aim of this study, therefore, was examine the relationship between the changes in SBF and FV during Braille reading. METHODS: We measured SBF of the finger, cutaneous vascular conductance (CVC), FV, and arterial blood pressure during Braille reading performed under blind conditions in thirty healthy subjects...

Tumor T cell antigens are both diagnostically and therapeutically valuable molecules. A large number of new peptides are examined as potential tumor epitopes each year, yet there is no infrastructure for storing and accessing the results of these experiments. We have retroactively cataloged more than 1000 tumor peptides from 368 different proteins, and implemented a web-accessible infrastructure for storing and accessing these experimental results. All peptides in TANTIGEN are labeled as one of the four categories: (1) peptides measured in vitro to bind the HLA, but not reported to elicit either in vivo or in vitro T cell response, (2) peptides found to bind the HLA and to elicit an in vitro T cell response, (3) peptides shown to elicit in vivo tumor rejection, and (4) peptides processed and naturally presented as defined by physical detection...

Multiple sclerosis (MS) is an autoimmune disease that affects the central nervous system (CNS), disrupting autonomic function. The aim of this study was to test the hypothesis that individuals with MS have blunted control of thermoregulatory reflex increases in sweat rate (SR) and cutaneous vasodilation compared to controls during a passive whole-body heat stress (WBH). Eighteen individuals with relapsing-remitting MS and 18 healthy controls (CON) participated in the study. Core temperature (Tcore), skin temperature, heart rate, arterial blood pressure (10 min intervals), skin blood flow (laser-Doppler flux: LDF), and SR were continuously measured during normothermic baseline (34 °C water perfusing a tube-lined suit) and WBH (increased Tcore 0...

We previously reported that prostacyclin induces cutaneous vasodilatation, but not sweating, in younger and older men. Further, we demonstrated that nitric oxide synthase (NOS) and calcium-activated potassium (KCa ) channels contribute to the prostacyclin-induced cutaneous vasodilatation in younger men, although these contributions are diminished in older men. Given the effects of ageing may differ between men and women, the above results cannot be simply applied to women. In this study, cutaneous vascular conductance (CVC) and sweat rate were evaluated in younger (22 ± 3 years) and older (55 ± 7 years) women (10 per group) at four intradermal forearm skin sites treated with either: (1) lactated Ringers without any drug (Control), (2) 10 mm L-NNA, a non-specific NOS inhibitor, (3) 50 mm tetraethylammonium (TEA), a non-specific KCa channel blocker, or (4) 10 mm L-NNA + 50 mm TEA...

The self-assembly of lipid bilayer membranes to enclose functional biomolecules, thus defining a "protocell," was a seminal moment in the emergence of life on Earth and likely occurred at the micro-environment of the mineral-water interface. Mineral-lipid interactions are also relevant in biomedical, industrial and technological processes. Yet, no structure-activity relationships (SARs) have been identified to predict lipid self-assembly at mineral surfaces. Here we examined the influence of minerals on the self-assembly and survival of vesicles composed of single chain amphiphiles as model protocell membranes...

BACKGROUND: Correction of coagulopathy prior to central venous catheter (CVC) placement is advocated by guidelines, while retrospective studies support restrictive use of transfusion products. STUDY DESIGN AND METHODS: We conducted a mixed vignette and questionnaire web survey to investigate current practice and preferences for CVC placement. Clinical vignettes were used to quantify the tendency to administer platelet concentrate. A positive ß-coefficient is in favour of administering platelet concentrate...

We recently showed the varying roles of Ca(2+)-activated (KCa), ATP-sensitive (KATP) and voltage-gated (KV) K(+) channels in regulating cholinergic cutaneous vasodilation and sweating in normothermic conditions. However, it is unclear whether the respective contributions of these K(+) channels remain intact during dynamic exercise in the heat. Eleven young (23±4 years) males completed a 30-min exercise bout at a fixed rate of metabolic heat production (400 W), followed by a 40-min recovery period in the heat (35°C, 20% relative humidity)...

BACKGROUND: Identifying a central venous catheter (CVC) as the source of bacteremia requires drawing simultaneous blood cultures (BCs) from the CVC and peripheral site and correct labeling of the BC source. In our emergency center (EC), 52% of BCs collected from febrile cancer patients lacked source information, making the diagnosis and management of catheter-related bloodstream infections (CRBSIs) challenging. METHODS: Between January 2015 and June 2015, we conducted a quality improvement project in our EC aiming to increase the occurrence of simultaneous BC drawing with accurate source labeling by 10%...

Objective The National Kidney Foundation (NKF) Kidney Disease Outcome Quality Initiative (KDOQI) guidelines have recommended the use of arteriovenous fistula (AVF) at the initiation of dialysis. However, there are significant differences in the dialysis environments of Japan and the United States, and there are few people who receive hemodialysis via a central venous catheter (CVC) in Japan. The aim of the present study was to examine the association between the type of vascular access at the initiation of dialysis and the incidence of mortality in Japan...

Pediatric patients undergoing surgery for spinal deformity may benefit from central venous access to provide intraoperative monitoring and fluid resuscitation. For pediatric surgical patients requiring central access, we hypothesized that placing a peripherally inserted central catheter (PICC) line preoperatively should decrease time from induction of anesthesia to incision and result in improved patient safety and decreased operating room charges. This was a retrospective, nonrandomized, and case comparison study...

During heat stress, blunted increases in skin sympathetic nervous system activity (SSNA) and reductions in end-organ vascular responsiveness contribute to the age-related reduction in reflex cutaneous vasodilation. In older adults, folic acid supplementation improves the cutaneous vascular conductance (CVC) response to passive heating; however, the influence of folic acid supplementation on SSNA:CVC transduction is unknown. Fourteen older adults (66±1yrs, 8M/6F) ingested folic acid (5mg·day(-1)) or placebo for 6 weeks in a randomized, double-blind, crossover design...
