Authors: Delgadillo Jaime , Moreea Omar , Murphy Elizabeth , Ali Shehzad , Swift Joshua K. 
Published: October 2015

ObjectivesTo assess if telephone text message appointment reminders and orientation leaflets can increase the proportion of patients who attend brief interventions after being assessed as suitable for guided self‐help following cognitive behavioral therapy principles.MethodAttendance was operationally defined as having accessed at least 1 therapy appointment. A secondary outcome was the proportion of attenders who completed or dropped out of therapy. After initial assessment, 254 patients with depression and anxiety disorders were randomly assigned to 1 of 3 groups: (a) usual waitlist control, (b) leaflet, (c) leaflet plus text message. Differences in the proportions of patients who started and completed therapy across groups were assessed using chi‐square and logistic regression analyses.ResultsOverall, 63% of patients in this sample attended therapy. Between‐group differences were not significant for attendance, x2(2) = 3.94, p = .14, or completion rates, x2(2) = 2.98, p = .23. These results were not confounded by demographic or clinical characteristics.ConclusionsLow‐cost strategies appear to make no significant difference to therapy attendance and completion rates.

ABSTRACTPurposeOur aim was to evaluate the diagnostic performance of ultrasonography (US) in the prenatal identification of teratomas and the perinatal outcome of the fetuses with those teratomas.MethodsIn this retrospective case series study, we searched the archives using the keywords “fetal mass” or “fetal tumor” or “fetal teratoma” and “sacrococcygeal teratoma,” diagnosed between 2009 and 2014, within the US database of our center.ResultsOne hundred seven fetuses were prenatally diagnosed as having a cystic or solid mass, tumor, or teratoma. Nineteen of those cases were diagnosed prenatally as having fetal teratoma, but that diagnosis could not be verified in three cases. In one fetus, the prenatal diagnosis could not be confirmed. The sensitivity of US in identifying fetal teratoma was 100% and the false‐positive rate, 3.3%. Six pregnancies complicated by a fetal teratoma were terminated. A normal karyotype was identified in all fetuses that underwent karyotyping. Among the nine women who continued their pregnancy, polyhydramnios was identified in four fetuses; although high‐output heart failure was also identified in two of those fetuses during prenatal follow‐up, none developed hydrops. On delivery, nine infants were born alive, but three (33.3%) of them died within the early neonatal period.ConclusionsUS has very high sensitivity and low false‐positive rates in identifying fetal teratoma prenatally. The risk of chromosomal abnormalities is very low in fetuses with teratoma, and their prognosis depends on the location and size of the tumor and any associated perinatal complications. © 2015 Wiley Periodicals, Inc.

The relationship between health and cell‐mediated immunity measured in ecology: Phytohaemagglutinin skin‐swelling test mirrors blood cellular composition
Authors: Bílková Barbora , Vinklerová Jitka , Vinkler Michal 
Published: October 2015

ABSTRACTThe phytohaemagglutinin (PHA) skin‐swelling test, a common ecological method for measuring immune responsiveness, uses a subcutaneous injection of PHA to induce an inflammatory response with metrically measurable swelling. Both the immunological basis of this response and the role of pre‐exposure physiology remain poorly understood, however, preventing predictions of costs and benefits of immunity investments revealed by the test and their relationship to life‐history traits. In this study, we measure PHA‐triggered tissue swelling, cellular infiltration into inflamed tissue, and haematological changes in zebra finches Taeniopygia guttata, with the aim of identifying those cell types involved in activation of PHA‐induced skin swelling. We show that the inflammation underlying the swelling response is dependent on initial haematological state and alters the composition of circulating leukocytes. Injection of PHA decreased heterophil and monocyte frequency and increased basophil frequency, suggesting changes in leukocyte trafficking and haematopoiesis. Higher initial basophil and lymphocyte frequencies in peripheral blood were associated with increased swelling. High pre‐treatment blood lymphocyte levels led to intense lymphocyte migration into inflamed tissue, while high initial basophil levels resulted in lower cellular infiltration. Our results show two possible directions in the association between pre‐exposure health and swelling response: (i) a lymphocyte‐based pathway that leads to higher responsiveness in high‐quality healthy individuals capable of higher energy and resource investment, or (ii) higher responsiveness in diseased individuals with initially elevated basophil levels and pre‐activated immunity. Haematological investigation, therefore, facilitates interpretation of PHA skin‐swelling test results in ecological immunology, explaining ca. 20 % of variation in skin‐swelling data. J. Exp.

Response of white mustard (Sinapis alba) and the soil microbial biomass to P and Zn addition in a greenhouse pot experiment
Authors: Khan Khalid Saifullah , Joergensen Rainer Georg 
Published: October 2015

AbstractA 45‐d pot experiment was carried out to investigate the response of white mustard and the soil microbial biomass after Zn and P addition to a P deficient silt loam. The underlying hypothesis was that P application reduces the Zn availability to crops and microbial biomass. White mustard was supplied with different levels of P (0, 50, and 100 µg g−1 soil) and Zn (0, 10, and 20 µg g−1 soil). Amendments of P generally reduced extractable Zn, shoot Zn and soil microbial biomass Zn. Amendments of P generally decreased the microbial biomass C/P ratio. At 20 µg Zn g−1 soil, a negative effect on the microbial biomass C/P ratio was observed, suggesting that high contents of extractable Zn have a negative impact on the microbial P uptake. However, the minimum Zn requirements of soil microorganisms and the consequences of microbial Zn deficiency for soil microbiological processes are completely unknown.

AbstractThis paper presents a novel compensation pixel circuit for active‐matrix organic light‐emitting diode displays, in which the coupling effect mask technology is developed to compensate the threshold voltage of driving thin‐film transistor whether it is positive or negative. Twenty discrete compensation pixel circuits have been fabricated by In‐Zn‐O thin‐film transistors process. It is measured that the non‐uniformity of the proposed pixel circuit is significantly reduced with an average value of 8.6%. Furthermore, the organic light‐emitting diode emission current remains constant during 6 h continuous operation, which also confirms the validity of the proposed pixel circuit.

Published: October 2015

AbstractMindfulness and self‐compassion are overlapping, but distinct constructs that characterize how people relate to emotional distress. Both are associated with posttraumatic stress disorder (PTSD) and may be related to functional disability. Although self‐compassion includes mindful awareness of emotional distress, it is a broader construct that also includes being kind and supportive to oneself and viewing suffering as part of the shared human experience—a potentially powerful way of dealing with distressing situations. We examined the association of mindfulness and self‐compassion with PTSD symptom severity and functional disability in 115 trauma‐exposed U.S. Iraq/Afghanistan war veterans. Mindfulness and self‐compassion were each uniquely, negatively associated with PTSD symptom severity. After accounting for mindfulness, self‐compassion accounted for unique variance in PTSD symptom severity (f2 = .25; medium ES). After accounting for PTSD symptom severity, mindfulness and self‐compassion were each uniquely negatively associated with functional disability. The combined association of mindfulness and self‐compassion with disability over and above PTSD was large (f2 = .41). After accounting for mindfulness, self‐compassion accounted for unique variance in disability (f2 = .13; small ES). These findings suggest that interventions aimed at increasing mindfulness and self‐compassion could potentially decrease functional disability in returning veterans with PTSD symptoms.

Published: October 2015

AbstractThe aim of the study was to investigate the occurrence of methicillin‐resistantStaphylococcus pseudintermedius(MRSP) in healthy dogs and further to determine genetic relatedness between carrier isolates and clinicalMRSPfrom dogs in Norway. A total of 189 healthy dogs visiting ten veterinary clinics were screened forMRSPduring the period February to April 2013. Carrier isolates were susceptibility tested with disk diffusion and genotyped using multilocus sequence typing (MLST) and pulsed‐field gel electrophoresis (PFGE). Forty‐nine clinicalMRSPwere characterized for comparison. These isolates were collected from July 2008 to April 2013 and represent allMRSPindex isolates from eachMRSP‐positive dog detected in Norway until April 2013. Geographical distribution of allMRSPcases was investigated using the ArcGIS9.3 Software.MRSPwas detected from five (2.6%) healthy dogs, sampled at three different clinics. The isolates grouped into three sequence types (STs):ST252 (two isolates),ST71 (two isolates) andST306 (one isolate).MRSPfrom dogs sampled at the same animal clinic belonged to the sameSTand produced identicalPFGEpattern. The 49 clinicalMRSPgrouped into 15STs;ST258 (n = 17),ST71 (n = 10), andST305 (n = 4) were the most prevalent. TheMRSPcarrier isolates were genetically related toMRSPvariants from dogs with infections asST306 (from a carrier) is related toST258.MRSP ST252, found in two carriers, was also present among the clinicalMRSPisolates. Altogether theMRSPisolates were genetically diverse andMRSPof other lineages thanST71 continues to disseminate in Norway. Susceptibility testing showed thatMRSPisolates of theST71 lineage were the most multiresistant. Our study showed thatMRSPcould be detected in healthy dogs without infections and with no recent history of antimicrobial therapy stressing the need for future monitoring, infection control and prudent use of antimicrobial agents.
Self‐organization of “fibro‐axonal” composite tissue around unmodified metallic micro‐electrodes can form a functioning interface with a peripheral nerve: A new direction for creating long‐term neural interfaces

Published: October 2015

ABSTRACTIntroductionA long‐term peripheral neural interface is an area of intense research. The use of electrode interfaces is limited by the biological response to the electrode material.MethodsWe created an electrode construct to harbor the rat sciatic nerve with interposition of autogenous adipose tissue between the nerve and the electrode. The construct was implanted for 10 weeks.ResultsImmunohistochemistry showed a unique laminar pattern of axonal growth layered between fibro‐collagenous tissue, forming a physical interface with the tungsten micro‐electrode. Action potentials transmitted across the intrerface showed mean conduction velocities varying between 6.99 ± 2.46 and 20.14 ± 4 m/s.ConclusionsWe have demonstrated the feasibility of a novel peripheral nerve interface through modulation of normal biologic phenomena. It has potential applications as a chronic implantable neural interface. Muscle Nerve 53: 789–796, 2016
A mixed‐method study of pain management practice in a UK children's hospital: identification of barriers and developing strategies to maintain effective in‐patient paediatric pain management

Published: October 2015

AbstractAimTo assess Acute Pain Service and paediatric pain management efficacy in a UK specialist paediatric hospital to inform wider recommendations for future sustainability.BackgroundUK paediatric acute pain services vary. Although comprehensive pain management guidelines exist, consensus on the best model of care is lacking. Worldwide, medical and pharmacological advances and rapid patient turnover have increased the challenges of managing hospitalized children's pain. Simultaneously nurses, who deliver the bulk of pain management, have experienced reduction in skill mix and training opportunities. Specialist Acute Pain Services have evolved to meet these demands; their overall efficacy is unknown.DesignThis mixed‐methods study explores pain management practice at a UK paediatric hospital to assess current efficacy and future sustainability.MethodA 2013 case note review of all Acute Pain Services referrals over 14 days were compared with an interval sample of concurrent non‐referred inpatient children; seven semi‐structured interviews were conducted with a range of clinical staff.ResultsTwenty‐two referrals of 15 children were made; 15 comparison children were identified. All 30 children (100%) were appropriately referred/non‐referred. Acute Pain Services cases experienced higher pain levels, were more likely to have long term conditions, longer hospital stay and repeat admissions. Three key themes emerged through interview analysis: ‘addressing pain’, ‘changing contexts’ ‘pain as an “expert” skill’. Increased specialization, reduced clarity between different pain modalities and decreased training opportunities had resulted in potentially unsustainable APS dependence.

AbstractPurposeThe aim of this study was to evaluate the psychometric properties of complementary and novel measures of partner interfering and partner supportive behaviors in cancer care (PIB‐C and PSB‐C).MethodsStructured telephone interviews were conducted with 378 women (aged 18–79) in partnered relationships and recruited from the Kentucky Cancer Registry. Psychometric analyses of PIB‐C and PSB‐C were used to determine scale reliability, and scale construct and predictive validity (correlations with indicators of partner abuse, symptoms of depression, anxiety, and stress after cancer).ResultsCronbach's alpha and split‐half calculations indicated excellent internal consistency of the 20‐item PIB‐C (0.936 and 0.87, respectively) and 12‐item PSB‐C (0.930 and 0.89). Three thematic clusters for the PIB‐C and two for the PSB‐C were identified through factor analyses. Regarding construct validity, higher PIB‐C and lower PSB‐C scores were associated with a measure of psychological impacts from abuse. Predictive validity was suggested through (1) lower PSB‐C associated with depression, (2) higher PIB‐C associated with anxiety, and (3) higher perceived stress associated with higher PIB‐C/lower PSB‐C scores.ConclusionBoth PIB‐C and PSB‐C have strong psychometric properties and distinguish partner behaviors more likely to negatively impact women's depression, anxiety, and stress during cancer care/recovery. Use of these measures may assist clinical teams in comprehensively assessing women patients' home environment to best ensure cancer care/recovery. Copyright © 2015 John Wiley & Sons, Ltd.
Robust optimal estimation over networks: Application to battery state of charge estimation
Authors: Zhang Yiming , Sircoulomb Vincent , Langlois Nicolas 
Published: October 2015

SummaryIn this paper, we provide a general framework for robust optimal estimation over a lossy and delayed network. A threshold principle is introduced to integrate network‐induced uncertainties into packet losses, which are modeled with a Bernoulli process. Based on stability conditions derived from two Riccati equations, we show the existence of critical observation arrival probabilities below which the optimal estimator stochastically fails to converge. Moreover, the result is extended to a real system with variable process disturbance, which has an indicator for its admissible bound in terms of a given restriction of estimation accuracy. The proposed method is experimented on a specific automobile application, the battery state of charge estimation. Copyright © 2015 John Wiley & Sons, Ltd.
A comprehensive study of flooding attack consequences and countermeasures in Session Initiation Protocol (SIP)
Authors: Hussain Intesab , Djahel Soufiene , Zhang Zonghua , Naït‐Abdesselam Farid 
Published: October 2015

AbstractSession Initiation Protocol (SIP) is widely used as a signaling protocol to support voice and video communication in addition to other multimedia applications. However, it is vulnerable to several types of attacks because of its open nature and lack of a clear defense line against the increasing spectrum of security threats. Among these threats, flooding attack, known by its destructive impact, targets both of SIP User Agent Server (UAS) and User Agent Client (UAC), leading to a denial of service in Voice over IP applications. In particular, INVITE message is considered as one of the major root causes of flooding attacks in SIP. This is due to the fact that an attacker may send numerous INVITE requests without waiting for responses from the UAS or the proxy in order to exhaust their respective resources. Most of the devised solutions to cope with the flooding attack are either difficult to deploy in practice or require significant changes in the SIP servers implementation. Apart from these challenges, flooding attacks are much more diverse in nature, which makes the task of defeating them a real challenge. In this survey, we present a comprehensive study of flooding attack against SIP, by addressing its different variants and analyzing its consequences. We also classify the existing solutions according to the different flooding behaviors they are dealing with, their types, and targets. Moreover, we conduct a thorough investigation of the main strengths and weaknesses of these solutions and deeply analyze the underlying assumptions of each of them for better understanding of their limitations. Finally, we provide some recommendations for enhancing the effectiveness of the surveyed solutions and address some open challenges. Copyright © 2015 John Wiley & Sons, Ltd.
On the use of variability operations in the V‐Modell XT software process line
Authors: Kuhrmann Marco , Méndez Fernández Daniel , Ternité Thomas 
Published: October 2015

AbstractSoftware process lines provide a systematic approach to develop and manage software processes. It defines a reference process containing general process assets, whereas a well‐defined customization approach allows process engineers to create new process variants, for example, by extending or modifying process assets. Variability operations are an instrument to realize flexibility by explicitly declaring required modifications, which are applied to create a procedurally generated company‐specific process. However, little is known about which variability operations are suitable in practice. In this article, we present a study on the feasibility of variability operations to support the development of software process lines in the context of the V‐Modell XT. We analyze which variability operations are defined and practically used. We provide an initial catalog of variability operations as an improvement proposal for other process models. Our findings show that 69 variability operation types are defined across several metamodel versions of which, however, 25 remain unused. The found variability operations allow for systematically modifying the content of process model elements and the process documentation, and they allow for altering the structure of a process model and its description. Furthermore, we also find that variability operations can help process engineers to compensate process metamodel evolution. Copyright © 2015 John Wiley & Sons, Ltd.
Positron emission tomography quantification of serotonin transporter binding in medication‐free bipolar disorder
Authors: Miller Jeffrey M. , Everett Benjamin A. , Oquendo Maria A. , Ogden R. Todd , Mann J. John , Parsey Ramin V. 
Published: October 2015

ABSTRACTObjectives: Bipolar disorder (BD) is associated with abnormalities in the serotonin transporter (5‐HTT), but specific in vivo findings have been discrepant. Using positron emission tomography (PET) and [11C]DASB, we compared 5‐HTT binding between unmedicated depressed BD subjects and healthy volunteers (HVs). Experimental Design: 5‐HTT binding in six brain regions was compared between 17 depressed, unmedicated BD subjects and 31 HVs, using the outcome measure of VT/fP (proportional to the total number of available transporters). Alternative outcome measures were examined as well. 47% of BD were BP I; and 65% reported a prior suicide attempt. Principal Observations: 5‐HTT binding (VT/fP) did not differ between BD and HV groups considering six brain regions of interest simultaneously (P = 0.24). In contrast, alternative outcome measures (BPF*, BPP*, and BPND*) indicated lower binding in BD compared with HV across these six regions of interest (BPF*: P = 0.047; BPP*: P = 0.032; BPND*: P = 0.031). 5‐HTT binding was unrelated to suicide attempt history, depression severity, bipolar subtype, or history of past substance use disorder. Conclusions: Choice of outcome measure strongly affects comparisons of serotonin transporter binding using PET with [11C]DASB. We do not find evidence of abnormal 5‐HTT binding in bipolar depression using our primary outcome measure, VT/fP. However, we did observe lower 5‐HTT binding in BD with alternative outcome measures that are frequently used with [11C]DASB. Relative merits and assumptions of different outcome measures are discussed. Evaluation in larger samples and during different mood states, including remission, is warranted.
