Introduction / objectives The frequent use of peripheral venous catheters (PVC) generate a significant number of infections. Since 2005, a standard recommendation edited by the French Society for Hospital Hygiene has been promoted in healthcare facilities (HCF). In 2009, the French Group for Evaluation of Practices concerning Hospital Hygiene (GREPHH) has provided an evaluation tool for PVC pra...

•We reviewed 185 PVC catheter ablation cases and identified 17 in which PVCs were successfully ablated in the aortic cusps.•The MDI measured 0.53 ± 0.10 (median 0.50, IQR 0.47-0.60).•In all (100%) cases MDI was > 0.40 and in 7 (41%) cases it was > 0.55.•Pseudo-delta wave was absent in all but one PVC•PVC origin in the aortic cusps should be considered along with the epicardium when MDI is in th...

Forebody pneumatic vortex control has previously been demonstrated through full-scale flight test to be effective for directional control of aircraft at low Mach number and high angle-ofattack flight conditions. The objective of the present research was to investigate the suitability of two-axis (wing, and vertical tail) pneumatic vortex lateral/directional control of a current fighter-type air...

There has been a significant and growing concern over nosocomial medical device infections. Previous studies have demonstrated that embedding nanoparticles alone (specifically, zinc oxide [ZnO]) in conventional polymers (eg, polyvinyl chloride [PVC]) can decrease bacteria growth and may have the potential to prevent or disrupt bacterial processes that lead to infection. However, little to no st...

A prospective randomized, controlled, single-blinded trial to compare the effectiveness and safety of heparin saline (HS) to those of normal saline (NS) as flushing and locking solutions for peripheral venous catheter (PVC) in decompensated liver cirrhosis (DLC) patients.Patients with DLC at our institution between April 2012 and March 2013 were enrolled after obtaining informed consent. The pa...

BACKGROUND Left ventricular (LV) dyssynchrony caused by premature ventricular contractions (PVCs) has been proposed as a mechanism of PVC-induced cardiomyopathy. We sought to understand the impact of different PVC locations and coupling intervals (prematurity) on LV regional mechanics and global function of the PVC beat itself. METHODS AND RESULTS Using our premature pacing algorithm, pentage...

The respiratory health of workers exposed to polyvinylchloride (PVC) dust has been investigated in 818 men sampled from the work force of a factory manufacturing PVC. In a cross-sectional survey, the lung function and prevalences of respiratory symptoms and chest radiographic abnormalities were compared with estimates of individual PVC dust exposures based on detailed occupational histories and...

We fabricated a soft thin-film vibrotactile actuator, which can be easily inserted into wearable devices, based on an electroactive PVC gel. One of the most important factors in fabricating a soft and thin vibrotactile actuator is to create vibrational force strong enough to stimulate human skin in a wide frequency range. To achieve this, we investigate the working principle of the PVC gel and ...

Premature ventricular contraction (PVC) is one of the most serious arrhythmias. Without early diagnosis and proper treatment, PVC can result in significant complications. In this paper, a novel feature extraction method based on a sparse auto-encoder (SAE) and softmax regression (SR) classifier was used to differentiate PVCs from other common Non-PVC rhythms, including normal sinus (N), left bu...
