Obtaining central venous access is one of the most commonly performed procedures in hospital settings. Multiple devices such as peripherally inserted central venous catheters, tunneled central venous catheters (eg, Hohn catheter, Hickman catheter, C. R. Bard, Inc, Salt Lake City UT), and implantable ports are available for this purpose. The device selected for central venous access depends on the clinical indication, duration of the treatment, and associated comorbidities. It is important for health care providers to familiarize themselves with the types of central venous catheters available, including information about their indications, contraindications, and potential complications, especially the management of catheters in the setting of catheter-related bloodstream infections...

We have performed a multiscale approach to study the influence of peripheral substitution in the semiconducting properties of discotic liquid-crystalline triindoles. Charge carrier mobility as high as 1.4 cm(2) V(-1) s(-1) was experimentally reported for triindoles substituted with alkynyl chains on the periphery (Gómez-Lor et al. Angew. Chem., Int. Ed., 2011, 50, 7399-7402). In this work, our goal is to get a deeper understanding of both the molecular electronic structure and microscopic factors affecting the charge transport properties in triindoles as a function of the spacer group connecting the central cores with the external alkyl chains (i...

Essentials How best to quantify thrombosis risk with peripherally inserted central catheters (PICC) is unknown. Data from a registry were used to develop the Michigan Risk Score (MRS) for PICC thrombosis. Five risk factors were associated with PICC thrombosis and used to develop a risk score. MRS was predictive of the risk of PICC thrombosis and can be useful in clinical practice. SUMMARY: Background Peripherally inserted central catheters (PICCs) are associated with upper extremity deep vein thrombosis (DVT)...

The present population-based study evaluates the management and complications of peripherally inserted central catheters (PICC) in all pediatric oncology patients diagnosed in Maritimes, Canada from 2000 to 2014. A total of 107 PICCs were placed in 87 (10.1%) pediatric oncology patients. A high percentage (33% and 44%, respectively) of the first and second PICC lines was associated with complications. Thrombosis, occlusion, and infection were the most frequent complications. Age above 10 years and left body side of insertion were significantly associated with PICC complications...

Background: Venoarterial extracorporeal membrane oxygenation (ECMO) provides systemic arterial support without directly unloading the left heart, which causes an elevated left ventricular (LV) pressure. The aim of the present study was to investigate the adjunctive application of the Impella device for LV unloading in patients during ECMO. Methods: This retrospective cohort study included patients who received Impella support in addition to venoarterial ECMO between April 2012 and December 2015. ECMO cannulation was performed peripherally or centrally, while the Impella device was surgically inserted into the femoral artery or the right axillary artery...

Peripherally inserted central catheter (PICC) and umbilical venous catheter (UVC) in terms of success rate, complications, cost and time of insertion in neonatal intensive care were compared. Neonates requiring vascular access for minimum 7 days were included. Sample size of 72 per group was determined. Trial was registered at Clinical Trials Registry of India (CTRI/2015/02/005529). Success rates of the UVC and PICC were 68.1% and 65.3%, respectively (p = 0.724). Mean (SD) time needed for PICC and UVC insertion was 34...

PURPOSE: To implement an end-to-end QA test of the radiation therapy imaging, planning and delivery process, aimed to assess the dosimetric agreement accuracy between planned and delivered treatment, in order to identify and correct possible sources of deviation. To establish an internal standard for machine commissioning acceptance. METHODS: A test involving all steps of the radiation therapy: imaging, planning and delivery process was designed. The test includes analysis of point dose and planar dose distributions agreement between TPS calculated and measured dose...

Objective This study aims to determine the frequency that umbilical venous catheters (UVCs) and peripherally inserted central catheters (PICCs) migrate into the cardiothymic silhouette after initial verification of correct placement. Study Design This is a single-center, retrospective study in neonates in whom a PICC or UVC was placed. The frequency of catheter tip migration into the cardiothymic silhouette requiring catheter manipulation was determined radiographically at 1 and 24 hours, respectively, after insertion...

REVIEW
V Donadio, R Liguori
Microneurography is a unique neurophysiological technique allowing direct recording of unmyelinated postganglionic sympathetic or afferent nociceptive fibers by tungsten needles inserted into a peripheral nerve fascicle. In recent years, microneurography has been used to ascertain autonomic impairments in central neurological disorders such as sleep disorders, Parkinson's disease, amyotrophic lateral sclerosis, or vasovagal syncope. Abnormal resting muscle sympathetic nerve activity (MSNA) and skin sympathetic nerve activity (SSNA) or the abnormal sympathetic response to arousal have been described in these disorders, thereby clarifying important pathophysiological aspects of the underlying impairment...

REVIEW

Cellular membranes define the functional geometry of intracellular space. Formation of new membrane compartments and maintenance of complex organelles require division and disconnection of cellular membranes, a process termed membrane fission. Peripheral membrane proteins generally control membrane remodeling during fission. Local membrane stresses, reflecting molecular geometry of membrane-interacting parts of these proteins, sum up to produce the key membrane geometries of fission: the saddle-shaped neck and hour-glass hemifission intermediate...

AIM: The aim of this survey was to estimate the prevalence of healthcare-associated infections (HAI) in the Slovak Republic (SR), distribution of causative pathogens, and risk factors. METHODS: The point prevalence survey (PPS) of HAI in the SR was carried out in 40 acute care hospitals, according to a standardized methodology developed by the European Centre for Disease Prevention and Control (ECDC). Data were collected according to the standard protocol at the country, hospital, and patient levels...

Central venous catheterization is a very common technique, although its complications can be multiple and sometimes fatal. A case is presented of cardiac tamponade by parenteral nutrition a few hours after moving a central venous catheter peripherally inserted a few days before. The diagnosis was made by echocardiography, and an emergency pericardiocentesis was performed, achieving complete recovery of the patient. Peripherally inserted central venous catheters are more likely to change their position secondary to the movements of the patient's arm, thus it is important to use soft catheters, make sure the tip lies above the carina to avoid perforation of the pericardial reflexion, and fix it well to the skin...

RANDOMIZED CONTROLLED TRIAL
Jona V Caparas, Jian-Ping Hu
BACKGROUND: According to the 2011 Infusion Nursing Standards of Practice, the low pH of intravenous vancomycin requires that it be administered through a central line. However, a careful review of the literature and a retrospective analysis of the experience at New York Hospital Queens (NYHQ) did not support the position of the Standards. PURPOSE: A prospective, controlled, randomized clinical trial was conducted to determine if intravenous vancomycin could be safely administered through a novel midline catheter (POWERWAND®, Access Scientific, San Diego, CA)...
