OBJECTIVE To assess the effectiveness of the Australian Medical Sheepskin in preventing sacral pressure ulcers (PUs), based on combined data from existing published trials. DESIGN AND SETTING Data from two randomised controlled trials (RCTs) among Australian hospital patients and one RCT among Dutch nursing home patients were pooled, comprising a total population of 1281 patients from 45 nurs...

In this paper, we consider a multi-channel cognitive radio network with multiple secondary users (SUs) and analyze the performance of users in the network. We assume primary users (PUs) adopt the automatic repeat request (ARQ) protocol at the medium access control layer. We have two main goals. Our first goal is to develop a cross-layer performance model of the cognitive radio network by consid...

The present study was performed to evaluate the ability of fosfomycin, a broad-spectrum antibiotic, to penetrate into abscess fluid. Twelve patients scheduled for surgical or computer tomography-guided abscess drainage received a single intravenous dose of 8 g of fosfomycin. The fosfomycin concentrations in plasma over time and in pus upon drainage were determined. A pharmacokinetic model was d...

RATIONALE AND OBJECTIVES The identification of body fluids in computed tomography poses a major diagnostic challenge. The chemical composition of body fluids deviates only slightly from water with very similar computed tomographic (CT) values, which typically range from 0 to 100 HU. The aim of this study was to assess physical and chemical properties of different body fluids in an ex vivo setti...

BACKGROUND We analyzed the outcome and complications of rigid (R-URS) and flexible (F-URS) ureteroscopic lithotripsy for treatment of proximal ureteric stone (PUS). SUBJECTS AND METHODS Retrospective data of 135 patients (93 males and 42 females) submitted to R-URS and F-URS for treatment of PUS in the period between July 2013 and January 2015 were investigated. (R-URS, group 1) was performed...

A 52-year-old man suffering from dilated cardiomyopathy underwent implantable left ventricular assist device (LVAD) insertion as a bridge to transplantation. He presented with evidence of LVAD-related mediastinitis and pump pocket infection 57 days after the LVAD implantation. The mediastinum was reopened and irrigated. A large amount of pus was observed around the outflow and inflow conduits a...

Cognitive radio plays a vital role in wireless communication. The cognitive radio composed of a transceiver which is used to check the channel vacancy for communication and avoids busy channels by shifting into unused channel. The scope for spectrum vacancy and area of coverage is increased by using cognitive radio. In cooperative relay network to transmit the primary traffic the primary users ...

In this paper, the performance of an underlay multiple-input multiple-output (MIMO) cognitive radio system is analytically studied. In particular, the secondary transmitter operates in a spatial multiplexing transmission mode, while a zero-forcing (ZF) detector is employed at the secondary receiver. Additionally, the secondary system is interfered by multiple randomly distributed single-antenna...

In this prospective study, among 47 clinically suspected cases of Liver abscess, 46 were diagnosed as of Amoebic origin. Confirmation of Amoebic Liver abscess (ALA) was done by ribosomal RNA (rRNA) gene detection from Liver abscess pus using real-time Polymerase Chain Reaction (PCR). In addition, microscopy for detection of the parasite in Liver abscess pus, and Lectin antigen as well as anti-L...

This paper introduces an application of artificial intelligence in the cognitive radio networks. The Cognitive Radio Network (CRN) provides a suitable environment for Secondary Users (SUs) to share the spectrum with Primary Users (PUs) in a non-interfering manner. In order to determine the availability of PUs bandwidth, SU can sense the spectrum in the channel. But, accurate and constant spectr...
