Abstract
BACKGROUND Early Intervention in Psychosis Services (EIS) for young people in England experiencing first-episode psychosis (FEP) were commissioned in 2002, based on an expected incidence of 15 cases per 100 000 person-years, as reported by schizophrenia epidemiology in highly urban settings. Unconfirmed reports from EIS thereafter have suggested higher than anticipated rates. The aim of this study was to compare the observed with the expected incidence and delineate the clinical epidemiology of FEP using epidemiologically complete data from the CAMEO EIS, over a 6-year period in Cambridgeshire, for a mixed rural-urban population. METHOD A population-based study of FEP (ICD-10, F10-39) in people aged 17-35 years referred between 2002 and 2007; the denominator was estimated from mid-year census statistics. Sociodemographic variation was explored by Poisson regression. Crude and directly standardized rates (for age, sex and ethnicity) were compared with pre-EIS rates from two major epidemiological FEP studies conducted in urban English settings. RESULTS A total of 285 cases met FEP diagnoses in CAMEO, yielding a crude incidence of 50 per 100 000 person-years [95% confidence interval (CI) 44.5-56.2]. Age- and sex-adjusted rates were raised for people from black ethnic groups compared with the white British [incidence rate ratio (IRR) 2.1, 95% CI 1.1-3.8]. Rates in our EIS were comparable with pre-EIS rates observed in more urban areas after age, sex and ethnicity standardization. CONCLUSIONS Our findings suggest that the incidence observed in EIS is far higher than originally anticipated and is comparable to rates observed in more urban settings prior to the advent of EIS. Sociodemographic variation due to ethnicity and other factors extend beyond urban populations. Our results have implications for psychosis aetiology and service planning.

Abstract
CONTEXT To enable study of psychological distress along the cancer journey, we need to be able to select and map validated measures through the cancer trajectory. OBJECTIVES To examine the performance of self-report measures for identifying clinically significant levels of psychological distress across the cancer patient trajectory. METHODS Electronic searches of Medline, PsychInfo, CINAHL, EmBase, The Cochrane Library, AMED, BNI, ASSIA, and Web of Science were undertaken. Only studies of self-report measures that used validated diagnostic tools for psychiatric diagnosis as the criterion measure were included. We then further limited our focus to those papers that specified a trajectory stage. RESULTS Forty-eight different self-report measures were reported in the 85 papers identified. The Hospital Anxiety and Depression Scale (HADS) was the most frequently reported measure (23 times). Several other measures were reported between two and four times, but most (37) measures were reported only once. Twenty-two of the 85 included papers reported measure performance by trajectory stage. Best performing measures based on validation data available could be identified for each trajectory stage: for pretreatment, the HADS for identifying depression; during treatment, the HADS and Mental Health Inventory-5 (MHI-5) together for identifying clinically significant distress; post-treatment, the HADS for identifying depression; and at recurrence and during the palliative phase, the Brief Edinburgh Depression Scale (BEDS) for identifying depression. CONCLUSION No single measure had evidence to support use throughout the illness trajectory in a longitudinal study, but the HADS, in combination with the MHI-5, was supported during the cancer treatment phase, and BEDS in the palliative care phase.

Abstract
A high-resolution x-ray imaging crystal spectrometer, whose concept was tested on NSTX and Alcator C-Mod, is being designed for the large helical device (LHD). This instrument will record spatially resolved spectra of helium-like Ar(16+) and will provide ion temperature profiles with spatial and temporal resolutions of <2 cm and ≥10 ms, respectively. The spectrometer layout and instrumental features are largely determined by the magnetic field structure of LHD. The stellarator equilibrium reconstruction codes, STELLOPT and PIES, will be used for the tomographic inversion of the spectral data.

Abstract
The x-ray imaging crystal spectrometer (XICS) for the Korea Superconducting Tokamak Advanced Research has been first applied for the experimental campaign in 2009. The XICS was designed to provide measurements of the profiles of the ion and electron temperatures from the heliumlike argon (Ar XVII) spectra. The basic functions of the XICS are properly working although some satellites lines are not well matched with the expected theoretical values. The initial experimental results from the XICS are briefly described.

Abstract
We have examined the observed currents in the front foils of the JET Faraday cup lost alpha particle diagnostic KA-2. In particular, we have sought to understand the currents during Ohmic plasmas for which the ion flux at the detectors was initially assumed to be negligible. We have considered two sources of this current: plasma ions (both deuterium and impurity) in the vicinity of the detector (including charge exchange neutrals) and photoemission from scattered UV radiation. Based upon modeling and empirical observation, the latter source appears most likely and, moreover, seems to be applicable to the currents in the front foil during ELMy H-mode plasmas. A very thin gold or nickel foil attached to the present detector aperture is proposed as a solution to this problem, and realistic calculations of expected fluxes of lost energetic neutral beam ions during TF ripple experiments are presented as justification of this proposed solution.

Abstract
A new set of analytic formulas describes the transmission of soft x-ray continuum radiation through a metallic foil for its application to fast electron temperature measurements in fusion plasmas. This novel approach shows good agreement with numerical calculations over a wide range of plasma temperatures in contrast with the solutions obtained when using a transmission approximated by a single-Heaviside function [S. von Goeler et al., Rev. Sci. Instrum. 70, 599 (1999)]. The new analytic formulas can improve the interpretation of the experimental results and thus contribute in obtaining fast temperature measurements in between intermittent Thomson scattering data.

Abstract
BACKGROUND AND PURPOSE Psychological disorders are recognized as an important and common problem after stroke but little is known about their longer-term effects on functional outcomes. We investigated the trajectory of psychological symptoms after stroke and studied their impact on physical functional recovery. METHODS The Stroke Outcomes Study was a prospective cohort study conducted in West Yorkshire, UK, from 2002 to 2006. Baseline assessments were conducted within 2 to 6 weeks of an index stroke event and follow-up at 9, 13, 26, and 52 weeks thereafter. Measures of psychological symptoms (assessed using the 28-item General Health Questionnaire) and function (modified Barthel Index) were completed at each visit. Longitudinal latent class analysis identified psychological symptom trajectories. Logistic regression modeled poor functional outcome. Multiple imputation was used as a sensitivity analysis. RESULTS Five hundred ninety-two (55% of eligible patients) consented to participate. Four hundred forty-four (76%) complete sets of data (5 time points) were obtained for analysis. Four distinct classes of patients emerged from the analyses based on trajectory of psychological symptoms in the first 26 weeks after stroke. There was a strong association between functional outcome and class as defined by psychological symptom trajectory, which was not explained by age, sex, or initial disability after stroke. CONCLUSIONS Currently, the assessment of psychological distress is concentrated in the first weeks after stroke. Our results suggest that the timing of assessment and intervention needs to be reconsidered to take into account the trajectory of psychological symptoms rather than assessment at a single time point.

Abstract
The main focus of lower limb physical performance assessment in people with haemophilia (PWH) has usually been on function, muscle strength and joint flexibility. The impact of haemophilic arthropathy on balance and falls risk is relatively under-explored. The aim of this study was to evaluate balance and related performance in PWH compared with age and gender matched healthy controls. It involved a comprehensive suite of clinical and laboratory measures of static and dynamic balance, mobility, strength, physical activity and falls efficacy completed in 20 PWH (mean age 39.4, 100% male) and 20 controls. Fifty percent of PWH reported falls in the past 12 months. Moderate impairment of balance and related measures were identified in PWH compared with the controls, with an average 35% difference between groups. Significant differences were evident between groups on both clinical and laboratory measures, including measures of dynamic bilateral stance balance [limits of stability measures on the laboratory test, functional reach; (P < 0.001); dynamic single leg balance (Step Test, P < 0.001)], gait and mobility (gait speed, step width and turning measures on the laboratory test, timed up and go test; P < 0.001); muscle strength (timed sit to stand, P = 0.002; quadriceps strength, P < 0.001); and activity level and falls efficacy, (P < 0.004). The dynamic clinical and laboratory measures testing similar domains of balance, gait and mobility had moderate correlations (0.310 < r < 0.531, P < 0.01). Moderate impairments in balance, mobility and related measures were identified in PWH, compared with the control group. Clinicians should include assessments of balance and related measures when reviewing adults with haemophilia.

Abstract
AIM To evaluate the sensitivity and specificity of magnetic resonance imaging (MRI) computer-aided detection (CAD) for breast MRI screen-detected lesions recommended for biopsy in a high-risk population. MATERIAL AND METHODS Fifty-six consecutive Breast Imaging Reporting and Data System (BI-RADS) 3-5 lesions with histopathological correlation [nine invasive cancers, 13 ductal carcinoma in situ (DCIS) and 34 benign] were retrospectively evaluated using a breast MRI CAD prototype (CAD-Gaea). CAD evaluation was performed separately and in consensus by two radiologists specializing in breast imaging, blinded to the histopathology. Thresholds of 50, 80, and 100% and delayed enhancement were independently assessed with CAD. Lesions were rated as malignant or benign according to threshold and delayed enhancement only and in combination. Sensitivities, specificities, and negative predictive values (NPV) were determined for CAD assessments versus pathology. Initial MRI BI-RADS interpretation without CAD versus CAD assessments were compared using paired binary diagnostic tests. RESULTS Threshold levels for lesion enhancement were: 50% to include all malignant (and all benign) lesions; and 100% for all invasive cancer and high-grade DCIS. Combined use of threshold and enhancement patterns for CAD assessment was best (73% sensitivity, 56% specificity and 76% NPV for all cancer). Sensitivities and NPV were better for invasive cancer (100%/100%) than for all malignancies (54%/76%). Radiologists' MRI interpretation was more sensitive than CAD (p=0.05), but less specific (p=0.001) for cancer detection. CONCLUSION The breast MRI CAD system used could not improve the radiologists' accuracy for distinguishing all malignant from benign lesions, due to the poor sensitivity for DCIS detection.
