Background: Though people of color (POC) are less likely to become afflicted with skin cancer, they are much more likely to die from it due to delay in detection or presentation. Very often, skin cancer is diagnosed at a more advanced stage in POC, making treatment difficult.The purpose of this research was to improve awareness regarding skin cancers in people of color by providing recommendati...

BACKGROUND The majority of primary care patients referred for bowel endoscopy do not have significant colorectal disease (SCD), and are - in hindsight - unnecessarily exposed to a small but realistic risk of severe endoscopy-associated complications. We developed a diagnostic strategy to better exclude SCD in these patients and evaluated the value of adding a faecal calprotectin point-of-care (...

The standing stock of particulate organic carbon (POC) was determined during "ve cruises in the Ross Sea in 1996 and 1997 and compared with primary production of carbon measured in short-term 14C-incubations and the #ux of organic carbon collected in moored sediment traps. POC concentrations were estimated from transmissometer pro"les that were calibrated with discrete POC bottle samples from e...

POC testing is defined as diagnostic testing at or near the site of patient care. Rapid measurement of the intensity of anticoagulation and, more recently, platelet inhibition allows dose titration of adjuvant medications such a heparin and antiplatelet agents during neuroendovascular procedures. However, knowledge among practicing physicians regarding the pathophysiologic basis of these measur...

The expansion of HIV antiretroviral therapy into decentralized rural settings will increasingly require simple point-of-care (POC) diagnostic tests that can be used without laboratory infrastructure and technical skills. New POC test devices are becoming available but decisions around which technologies to deploy may be biased without systematic assessment of their suitability for decentralized...

Point-of-care (POC) glucose technology is currently considered to be insufficiently accurate for the diagnosis of diabetes. The objective of this study was to investigate the diagnostic accuracy of an innovative, interference-resistant POC glucose meter (StatStrip glucose hospital meter, Nova Biomedical, USA) in subjects with a previous history of dysglycaemia, undergoing a 75 g diagnostic oral...

Nowadays IP Multimedia Subsystem (IMS) has been applied in more and more areas to deploy multimedia services to satisfy people’s willing to share services seamlessly accessed over wireless, wireline, cable, and Internet Protocols that lead to a new level of interoperability and deliverability of services anywhere, anytime and on any-type of termination device. By IMS Service Delivery Platform (...

Advantages of direct peroral cholangioscopy (POC) using an ultraslim endoscope include use of conventional endoscopy equipment, operation by a single endoscopist, and superior image quality of the biliary tree with easy application of enhanced endoscopy and a large working channel. The major diagnostic indications of this system are an evaluation of biliary strictures, filling defects, or uncle...

In side-channel analysis, the waveforms can be acquired misaligned. Several algorithms have been put forward to resynchronize signals, as a pretreatment before the attack proper. In this article, we examine two of them, namely amplitude-only and phase-only correlation (abridged AOC and POC), and introduce a third one, called thresholdPOC (T-POC) that corrects a flaw of the phase-only correlatio...

PURPOSE Multianalyte point-of-care (POC) devices are important to guide clinical decisions in critical care. However, the use of different devices in one hospital might cause problems. Therefore, we evaluated 3 commonly used POC devices and analyzed accuracy, reliability, and bias. METHODS Seventy-four arterial blood samples were analyzed by 3 POC devices (Cobas, Roche Diagnostics, Mannheim, ...
