Systolic Blood Pressure Control and Mortality After Stroke in Hypertensive Patients
Authors: Okin Peter M. , Kjeldsen Sverre E. , Devereux Richard B. 
Published: June 2015

Background and Purpose—
Hypertensive patients with electrocardiographic left ventricular hypertrophy are at increased risk of all-cause and cardiovascular death. Lowering blood pressure (BP) after stroke reduces the risk of recurrent stroke, but recent data suggest that lower systolic BP (SBP) measured 5 years after stroke is associated with increased mortality. Whether lower SBP is associated with increased short-term mortality after stroke in hypertensive patients is unclear.

Methods—
All-cause and cardiovascular mortality were examined in relation to average on-treatment SBP after stroke in 541 hypertensive patients with electrocardiographic left ventricular hypertrophy randomly assigned to losartan- or atenolol-based treatment who had new strokes during follow-up. Patients with on-treatment SBP<144 mm Hg (lowest tertile) and SBP>157 (highest tertile) were compared with patients with average SBP between 144 and 157.

Results—
During 2.02±1.65 years mean follow-up after incident stroke, 170 patients (31.4%) died, 135 (25.0%) from cardiovascular causes. In multivariate Cox analyses, adjusting for significant univariate predictors of mortality, compared with average SBP between 144 and 157, an average SBP<144 was a significant predictor of all-cause (hazard ratio, 1.81; 95% confidence interval, 1.20–2.73) and cardiovascular mortality (hazard ratio, 1.60; 95% confidence interval, 1.02–2.54), whereas patients who had an average SBP>157 had no significant increased risk of death.

Conclusions—
Lower achieved SBP (<144 mm Hg) is associated with a significantly increased risk of cardiovascular and all-cause mortality after initial stroke in hypertensive patients during short-term follow-up. Further study is required to determine ideal SBP goals after stroke.

Detection and Analysis of an Amplified Warming of the Sahara Desert
Authors: Cook Kerry H. , Vizy Edward K. 
Published: June 2015

Abstract
Evaluation of three reanalyses (ERA-Interim, NCEP-2, and MERRA) and two observational datasets [CRU and Global Historical Climatology Network (GHCN)] for 1979–2012 demonstrates that the surface temperature of the Sahara Desert has increased at a rate that is 2–4 times greater than that of the tropical-mean temperature over the 34-yr time period. While the response to enhanced greenhouse gas forcing over most of the globe involves the full depth of the atmosphere, with increases in longwave back radiation increasing latent heat fluxes, the dryness of the Sahara surface precludes this response. Changes in the surface heat balance over the Sahara during the analysis period are primarily in the upward and downward longwave fluxes. As a result, the warming is concentrated near the surface, and a desert amplification of the warming occurs. The desert amplification is analogous to the polar amplification of the global warming signal, which is concentrated at the surface, in part, because of the vertical stability of the Arctic atmosphere. Accompanying the amplified surface warming of the Sahara is a strengthening of both the summertime heat low and the African easterly jet and a weakening of the wintertime anticyclone and the low-level Harmattan winds. Potential implications of the desert amplification include decreases in mineral dust aerosols globally, decreases in wintertime cold air surge activity, and increases in Sahel rainfall.

Published: June 2015

Background Thymoma exhibits a range of histological and biological features and their imaging findings varies. Purpose To evaluate the associations between CT findings of thymomas and their classification according to the Masaoka staging system and World Health Organization (WHO) classification. Material and Methods Eighty-four patients with thymoma were evaluated. Comparisons between the CT findings of Masaoka stage I/II and III/IV lesions, and the WHO type A-B1 (low risk) and B2/B3 (high risk) lesions were performed. Results Stage III/IV thymomas (mean size, 60 mm) were significantly larger than stage I/II (45 mm) lesions and had more irregular shape and contour. Necrosis and calcification were observed in 16 (59%) and nine (33%) stage III/IV thymomas, and 16 (28%) and seven (12%) stage I/II lesions, respectively. Regarding the WHO classification, the high-risk thymomas displayed irregular shape and contour more often than low-risk lesions. There were significant differences between the patterns of mediastinal invasion seen in high- and low-risk groups; 21 (68%) vs. six (12%) lesions demonstrated mediastinal fat invasion, seven (23%) vs. two (4%) lesions exhibited great vessel invasion, five (16%) vs. 0 (0%) lesions displayed pericardial invasion, and 18 (58%) vs. 10 (20%) lesions invaded the lungs, respectively. Conclusion Masaoka stage III/IV thymomas were larger in size, had more irregular shape and contour, and exhibited necrosis and calcification more often than the stage I/II lesions. In the WHO classification, high-risk thymomas demonstrated more irregular shape and contour than low-risk thymomas.
Communication during goal-setting in brain injury rehabilitation: What helps and what hinders?

Published: June 2015

Introduction Setting goals with individuals with acquired brain injury may be challenging due to impairments in cognition and communication. The purpose of this study was to explore how occupational therapists' communication behaviours during goal-setting with individuals with traumatic brain injury facilitated and hindered this process. Method This exploratory study used a conversation analysis inspired approach and frequency calculations to analyse and interpret videotaped goal-setting sessions. Sequences of dialogue leading to, and distracting from, problem identification, a key step in goal-setting, were identified and analysed. Specific therapist behaviours that facilitated or hindered problem identification were subsequently distinguished. Results Acknowledgements and affirmations, open-ended questions about specific tasks and reflective listening, were found to lead to problem identification by the client (facilitators). Instances of disconnections were characterized by a single theme, ‘lack of uptake.' Examples of these hindrances to goal-setting included, abrupt topic shifts, lack of acknowlegement and failure to explore what the client said. Conclusion Clinicians should consider their language use during goal-setting interviews and aim to utilize conversational behaviours that are facilitative whilst minimizing those that distract to optimize their client's engagement during the problem identification phase of goal-setting.
Intimate partner violence, partner notification, and expedited partner therapy: a qualitative study

Published: June 2015

Summary Over one-third of women experience intimate partner violence (IPV) in their lifetime. IPV increases the risk of infection and re-infection with sexually transmitted infections (STIs). The extent to which health care providers consider IPV when recommending partner notification and expedited partner therapy is unknown. The objective of this qualitative study was to understand health care providers’ views on IPV and STIs when recommending partner treatment to patients with chlamydia. Using a purposive sampling strategy to include health care providers who treat young women at risk for chlamydia, 23 semi-structured, in-depth interviews were conducted. While some health care providers expressed concern for their patients’ safety and believed assessing for IPV was needed before provision of expedited partner therapy, nearly a third had not considered the links between IPV and STIs. Strategies used by health care providers to assess for IPV did not include inquiry about specific behaviours related to IPV, STI risk, and sexual coercion. Many health care providers understand the risk for IPV in the setting of STI treatment, yet a significant portion of those interviewed failed to recognise the link between IPV and STIs. Provider education is necessary to increase knowledge and implement more effective inquiry and counselling about IPV to more safely recommend expedited partner therapy.

Objectives First external validation of a preoperative scoring system (Guy’s) in patient selection for femoro-distal bypass grafting to single calf or pedal artery in critical limb ischemia (Fontaine III & IV/Rutherford grade IV, V & VI). Material and methods A prospective study of 76 ( n = 76) consecutive femoro-crural/pedal bypass grafts on 72 individuals ( n = 72) from 2008 to 2011 with 36 months mean follow-up was performed. All cases were scored against a previously designed and published scoring system (ranging from 0 to 10) based on: inflow, outflow, graft material, flow type, patent pedal vessels and diabetes mellitus. Results Preoperative score of 0–4 ( n = 37) demonstrated the primary patency of 27% at 10.3 months. This value for intermediate group 5–7 ( n = 34) was 70.6% at 18.9 months. The high-score group 8–10 ( n = 4) showed the longest primary patency (80%) at 27.3 months. Kaplan–Meier survival analysis exhibited a consistent and significant difference in primary assisted, secondary patency and overall limb/foot salvage amongst all individual scoring groups ( p < 0.001). Conclusion This study validates and complements the Guy’s scoring system and provides a platform for the identification of critical limb ischemia patients in whom the result of femoro-crural/distal bypass grafting is so poor that primary amputation may be both clinically and economically more justified.
Knowledge-based adaptable scheduler for SaaS providers in cloud computing
Authors: Motavaselalhagh Farzaneh , Safi Esfahani Faramarz , Arabnia Hamid Reza 
Published: June 2015

AbstractSoftware as a Service (SaaS) in Cloud Computing offers reliable access to software applications for end users over the Internet without direct investment in infrastructure and software. SaaS providers utilize resources of internal datacenters or rent resources from a public Infrastructure as a Service (IaaS) provider in order to serve their customers. Internal hosting can increase cost of administration and maintenance, whereas hiring from an IaaS provider can impact quality of service due to its variable performance. To surmount these challenges, we propose a knowledge-based admission control along with scheduling algorithms for SaaS providers to effectively utilize public Cloud resources in order to maximize profit by minimizing cost and improving customers’ satisfaction level. In the proposed model, the admission control is based on Service Level Agreement (SLA) and uses different strategies to decide upon accepting user requests for that minimal performance impact, avoiding SLA penalties that are giving higher profit. However, because the admission control can make decisions optimally, there is a need of machine learning methods to predict the strategies. In order to model prediction of sequence of strategies, a customized decision tree algorithm has been used. In addition, we conducted several experiments to analyze which solution in which scenario fit better to maximize SaaS provider’s profit. Results obtained through our simulation shows that our proposed algorithm provides significant improvement (up to 38.4 % cost saving) compared to the previous research works.
A randomised controlled trial of time-limited individual
placement and support: IPS-LITE trial

Published: June 2015

BackgroundIndividual placement and support (IPS) has been repeatedly demonstrated
to be the most effective form of mental health vocational rehabilitation.
Its no-discharge policy plus fixed caseloads, however, makes it expensive
to provide.AimsTo test whether introducing a time limit for IPS would significantly
alter its clinical effectiveness and consequently its potential
cost-effectiveness.MethodReferrals to an IPS service were randomly allocated to either standard
IPS or to time-limited IPS (IPS-LITE). IPS-LITE participants were
referred back to their mental health teams if still unemployed at 9
months or after 4 months employment support. The primary outcome at 18
months was working for 1 day. Secondary outcomes comprised other
vocational measures plus clinical and social functioning. The
differential rates of discharge were used to calculate a notional
increased capacity and to model potential rates and costs of
employment.ResultsA total of 123 patients were randomised and data were collected on 120
patients at 18 months. The two groups (IPS-LITE = 62 and IPS = 61) were
well matched at baseline. Rates of employment were equal at 18 months
(IPS-LITE = 24 (41%) and IPS = 27 (46%)) at which time 57 (97%) had been
discharged from the IPS-LITE service and 16 (28%) from IPS. Only 11
patients (4 IPS-LITE and 7 IPS) obtained their first employment after 9
months. There were no significant differences in any other outcomes.
IPS-LITE discharges generated a potential capacity increase of 46.5%
compared to 12.7% in IPS which would translate into 35.8 returns to work
in IPS-LITE compared to 30.6 in IPS over an 18-month period if the rates
remained constant.ConclusionsIPS-LITE is equally effective to IPS and only minimal extra employment is
gained by persisting beyond 9 months. If released capacity is utilised
with similar outcomes, IPS-LITE results in an increase by 17% in numbers
gaining employment within 18 months compared to IPS and will increase
with prolonged follow-up. IPS-LITE may be more cost-effective and should
be actively considered as an alternative within public services.
Indium Implantation onto Zeolite by Pulse Arc Plasma Process for the Development of Novel Catalysts
Authors: Yoshimura Satoru , Nishimoto Yoshihiro , Kiuchi Masato , Yasuda Makoto 
Published: June 2015

Abstract
Chemical substances that contain both indium (In) and silicon (Si) in close proximity catalyze certain organic chemical reactions. The implantation of In onto zeolite containing Si atoms was carried out by a pulse arc plasma process for the possible development of novel catalysts. X-ray photoelectron spectroscopy of the In-implanted zeolite revealed that In was successfully implanted. In addition, the In-implanted zeolite was capable of catalyzing an organic chemical reaction (i.e., Friedel–Crafts alkylation).
Case Report: Neuropathic pain in a patient with congenital insensitivity to pain

Published: June 2015

We report a unique case of a woman with Channelopathy-associated Insensitivity to Pain (CIP) Syndrome, who developed features of neuropathic pain after sustaining pelvic fractures and an epidural hematoma that impinged on the right fifth lumbar (L5) nerve root. Her pelvic injuries were sustained during painless labor, which culminated in a Cesarean section. She had been diagnosed with CIP as child, which was later confirmed when she was found to have null mutations of the SCN9A gene that encodes the voltage-gated sodium channel Nav1.7. She now complains of troubling continuous buzzing in both legs and a vice-like squeezing in the pelvis on walking. Quantitative sensory testing showed that sensory thresholds to mechanical stimulation of the dorsum of both feet had increased more than 10-fold on both sides compared with tests performed before her pregnancy. These findings fulfill the diagnostic criteria for neuropathic pain. Notably, she mostly only experiences the negative symptoms (such as numbness and tingling, but also electric shocks), and she has not reported sharp or burning sensations, although the value of verbal descriptors is somewhat limited in a person who has never felt pain before. However, her case strongly suggests that at least some of the symptoms of neuropathic pain can persist despite the absence of the Nav1.7 channel. Pain is a subjective experience and this case sheds light on the transmission of neuropathic pain in humans that cannot be learned from knockout mice.
How to set up for intravenous fluid therapy
Authors: Bloor Claire 
Published: June 2015

Introduction The use of intravenous fluid therapy (IVFT) is common in veterinary practice as there are many different types of patients requiring cardiovascular support. These patients include those with medical conditions, those being anaesthetised for surgery, and emergency patients. While fluid selection and administration rates are the remit of the veterinary surgeon (VS), registered veterinary nurses (RVN) are primarily responsible for pre-infusion blood sampling and testing, preparing infusions, obtaining intravenous access, administering the infusion and monitoring the patient's progress. This article will outline the indications for IVFT, discuss initial patient assessment, fluid selection and goals associated with fluid administration, before considering the preparation and administration of infusions, and subsequent patient monitoring.

Published: June 2015

AbstractIn this article, I seek to sharpen the discussion about my book Capital in the twenty-first century, and to address some of the many issues raised by the very interesting papers that were put together by the editors of Basic Income Studies. I start by summarizing the multidimensional approach to capital and power that I develop in my book. I then clarify the role played by r>g in my analysis of wealth inequality. Finally, I discuss some of the implications of my analysis for optimal taxation; the relation between wealth, welfare and power; the basic income proposal; and the regulation of capital and property relations.
Measuring association via lack of
co-monotonicity: the LOC index and a
problem of educational assessment
Authors: Qoyyimi Danang Teguh , Zitikis Ricardas 
Published: June 2015

Abstract
Measuring association, or the lack of it, between variables plays an important role in a variety of
research areas, including education,which is of our primary interest in this paper. Given, for example, student
marks on several study subjects, we may for a number of reasons be interested in measuring the lack of comonotonicity
(LOC) between the marks, which rarely follow monotone, let alone linear, patterns. For this
purpose, in this paperwe explore a novel approach based on a LOCindex,which is related to, yet substantially
different from, Eckhard Liebscher’s recently suggested coefficient of monotonically increasing dependence.
To illustrate the new technique,we analyze a data-set of student marks on mathematics, reading and spelling.

Published: June 2015

ObjectiveHypothalamic obesity in childhood craniopharyngioma (CP) patients carries a high risk for development of metabolic syndrome. In metabolic syndrome, the development of nonalcoholic fatty liver disease (NAFLD) is known. The aim of this study is to detect the risk for NAFLD in childhood-onset CP.DesignThis cross-sectional study included liver computed tomography (CT); ultrasound analysis of abdomen; measurements of serum parameters, height, weight and body composition; and daily medication of patients with childhood-onset CP.MethodsA total of 384 patients recruited in trials HIT Endo and KRANIOPHARYNGEOM 2000 were analyzed. Ninety-four survivors were included by fulfilling the criteria of proven hypothalamic involvement (HI), a minimum time interval of 5 years between diagnosis and study, and a minimum age of 18 years at the time of evaluation. A total of 19 patients agreed to participate. To quantify the degree of steatosis hepatis, analyses of liver density were performed once by non-contrasted CT of liver sections.ResultsNAFLD occurs in about 50% of CP patients with HI and is associated with elevated liver enzymes and homeostasis model assessment index. BMI is not an effective predictive factor but body fat mass measured by near-infrared spectroscopy (NIRS) is. Over half of CP patients (60%) with NAFLD are treated with stimulating agents, with risk of hepatic side effects.ConclusionsNAFLD is a major adverse late effect in childhood-onset CP. NIRS rather than BMI should be used to measure body composition and predict NAFLD. Stimulating agents for treatment of fatigue and daytime sleepiness in CP should be prescribed judiciously.
