The Facing Dementia Survey was undertaken to assess the awareness of and behaviours surrounding Alzheimer's disease (AD) and dementia among all key stakeholders in Europe. Interviews were conducted with more than 2500 persons, including caregivers, members of the general population, physicians, persons with AD and influencers of health care policy. Four key messages emerged from the results.

Study Objective: We evaluate the effectiveness of an emergency department (ED)-based outreach program in increasing the enrollment of uninsured children.

Methods: The study involved placing a full-time worker trained to enroll uninsured children into Medicaid or the State Children's Health Insurance Program in an inner-city academic children's hospital ED. Analysis was carried out for outpatient ED visits by insurance status, average revenue per patient from uninsured and insured children, proportion of patients enrolled in Medicaid and State Children's Health Insurance Program through this program, estimated incremental revenue from new enrollees, and program-specific incremental costs.

Background: Malignant melanoma has a good prognosis if treated early. Dermoscopy images of pigmented lesions are most commonly taken at x 10 magnification under lighting at a low angle of incidence while the skin is immersed in oil under a glass plate. Accurate skin lesion segmentation from the background skin is important because some of the features anticipated to be used for diagnosis deal with shape of the lesion and others deal with the color of the lesion compared with the color of the surrounding skin.

A cryogenic optical waveguide spectrometer that uses a Teflon-AF 2400 liquid core waveguide is described. In comparison to standard low-temperature absorption techniques, the liquid core waveguide approach not only affords the use of microliter samples but also provides significant improvements in sensitivity. Here we show low-temperature absorption spectra of various flavoproteins, including DNA photolyase, measured using this new technique.

Screening assays have been successfully developed for the detection of (anti-)oestrogenic substances in several fish species, including the fathead minnow (Pimephales promelas). Previous work suggested that pre-spawning adult fathead minnows might be an appropriate life-stage for developing a screen to detect endocrine active substances (EASs). Pre-spawning adult fathead minnows, in which their phenotypic sex could be determined, were exposed in flow-through systems to three reference substances for 21 days, at 25 degrees C.

The interaction between Schistosoma mansoni and platelets of non-immune mice has been studied in vivo and in vitro. A moderate thrombocytopaenia was observed in mice 2 days after they had been infected percutaneously with 200 cercariae. A rabbit anti-mouse platelet antiserum, 25 microL of which injected subcutaneously induced a nearly 900% reduction in blood platelet count 24 h later, was used to investigate the effects of severe thrombocytopaenia on S.

Bone plate design has evolved dramatically in recent years. The Dynamic Compression Plate (DCP) has been superseded by bi- and uni-cortical plates that claim a reduced interface contact between the plate and the underlying bone. It is believed that contact reduction ameliorates the localised ischaemia that develops subsequent to plate application.

Radiologists often examine X-rays of cervical, thoracic and lumbar vertebrae for determining the presence of osteoarthritis and osteoporosis. For individual vertebra assessment, the boundary increasingly digresses from the general rectangular shape as the vertebra becomes less normal in appearance. For an abnormal vertebra, bony growths ('osteophytes') may appear at the vertebral comers, resulting in a change in the vertebra's shape.

Image analysis techniques are introduced for evaluating disc space narrowing of cervical vertebrae interfaces from X-ray images. Four scale-invariant, distance transform-based features are presented for characterizing the spacing between adjacent vertebrae. K-means and self-organizing map clustering techniques are applied to estimate the degree of disc space narrowing using a four grade (0-3) scoring system, where 0 and 3 represent normal spacing and significant narrowing, respectively.

Selection of an appropriate suture requires a knowledge of many factors. These include its mechanical characteristics, its durability, the period of mechanical effectiveness and the tissue reactivity to the material. Absorbable suture materials were incubated in synovial fluid or phosphate buffered saline, at 37 degrees C, for periods up to 12 weeks.

This investigation developed the Wheelchair Users Functional Assessment (WUFA). Because no functional outcome tools exist that include many of the daily activities that are needed to be independent by individuals using manual wheelchairs, development of an appropriate tool was deemed important. Although the Functional Independence Measure (FIM) can be used to assess disability in those using a wheelchair, it only measures some aspects of basic activities of daily living (ADLs) and does not measure community independence.

Rupture of the biceps tendon occurs predominantly in the middle-aged and elderly, being predisposed through bicipital tendinitis and rotator cuff lesions. Surgical repair may be an option for those requiring strength in supination. This study compared the initial fixation strength of keyhole tenodesis (n = 7) and interference screw fixation by use of cadaveric specimens.

Beta-probes are a relatively new tool for tracer kinetic studies in animals. They are highly suited to evaluate new positron emission tomography tracers or measure physiologic parameters at rest and after some kind of stimulation or intervention. In many of these experiments, the knowledge of CBF is highly important.

Unlabelled: Treatment goals in severe midfacial trauma are restoration of function and appearance. Restoration of function is directed at multiple organ systems, which support visual acuity, airway patency, mastication, lacrimation, smelling, tasting, hearing, and facial expression. Victims of blunt facial trauma expect to look the same after surgical treatment as before injury.

Compelling lateral motion can be experienced when intensity differences between the two cars change over time. Whether our sensitivity to this dynamic interaural stimulation could be influenced by directional cues was the focus of the present study. On each trial, amplitude-modulated pure tones were presented either diotically (no-motion condition) or dichotically (motion condition), and participants indicated whether lateral motion was present or absent.

DNA photolyase (PL) is a monomeric flavoprotein that repairs cyclobutylpyrimidine dimers (CPDs) via photoinduced electron transfer from a reduced flavin adenine dinucleotide cofactor (FADH(-)) to the bound CPD. We have used subpicosecond UV transient absorption spectroscopy to measure the electron-transfer and repair kinetics of Anacystis nidulans DNA photolyase with dimeric and pentameric oligothymidine substrates. Here we show that the electron-transfer lifetime is 32 +/- 20 ps for the pentameric substrate.

A fuzzy logic-based color histogram analysis technique is presented for discriminating benign skin lesions from malignant melanomas in dermatology clinical images. The approach utilizes a fuzzy set for benign skin lesion color, and alpha-cut and support set cardinality for quantifying a fuzzy ratio skin lesion color feature. Skin lesion discrimination results are reported for the fuzzy ratio and fusion with a previously determined percent melanoma color feature over a data set of 258 clinical images.
