Comparison of noncontact and electroanatomic mapping to identify scar and arrhythmia late after the Fontan procedure.

BACKGROUND
The right atrium late after the Fontan procedure is characterized by multiple complex arrhythmia circuits. We performed simultaneous electroanatomic and noncontact mapping to assess the accuracy of both systems to identify scar and arrhythmia.


METHODS AND RESULTS
Mapping was performed in 26 patients aged 26.8+/-8.9 years, 18.7+/-4.4 years after Fontan surgery. The area and site of abnormal endocardium defined by electroanatomic mapping (bipolar contact electrogram <0.5 mV) were compared with those defined by noncontact mapping during sinus rhythm and by dynamic substrate mapping. Contact and reconstructed unipolar electrograms at a known distance from the multielectrode array, recorded by the noncontact system simultaneously at 452 endocardial sites, were compared for morphological cross correlation, timing difference, and amplitude. Mapping of arrhythmias was performed with both systems when possible. The median patient abnormal endocardium as defined by electroanatomic mapping covered 38.0% (range 16.7% to 97.8%) of the right atrial surface area, as opposed to 60.9% (range 21.3% to 98.5%) defined by noncontact mapping during sinus rhythm and 11.9% (range 0.4% to 67.3%) by dynamic substrate mapping. A significant decrease in electrogram cross correlation (P=0.003), timing (P=0.012), and amplitude (P=0.003) of reconstructed electrograms, but not of contact electrograms (P=0.742), was seen at endocardial sites >40 mm from the multielectrode array. Successful arrhythmia mapping by electroanatomic versus noncontact mapping was superior in 15 patients (58%), the same in 6 (23%), and inferior in 5 (19%; P=0.044).


CONCLUSIONS
Electroanatomic mapping is the superior modality for arrhythmia mapping late after the Fontan procedure. Noncontact mapping is limited by a significant reduction in reconstructed electrogram correlation, timing, and amplitude >40 mm from the multielectrode array and cannot accurately define areas of scar and low-voltage endocardium.
Improving force control performance by computational elimination of non-contact forces/torques

Regarding manipulators with wrist-mounted force/torque sensors a major issue is the high execution time of force-guided and force-guarded motions compared to purely position-controlled tasks. An important factor that aggravates the reduction of the execution time is the influence of non-contact forces, e.g. inertial forces, centrifugal forces, Coriolis forces, and associated torques, which are exerted onto the sensor by a load attached to it. Considering force-guided or force-guarded motions, these non-contact forces may significantly deteriorate contact detection and force control performance when executing dynamic movements. In addition to these disturbance forces/torques, resets of the force/torque sensor consume execution time. This paper presents an approach to eliminating all non-contact forces and associated torques from force/torque sensor measurements thus enabling pure contact force control. Apart from facilitating pure contact force control, the presented approach renders resets of the force/torque sensor unnecessary. To achieve this aim, the ten inertial parameters (mass, coordinates of the center of mass, and the elements of the inertia matrix) of the load attached to the sensor as well as the force/torque sensor offsets are estimated on-line employing a variant of the recursive instrumental variables method. These parameters are used to calculate the non- contact forces/torques acting upon the sensor. The current non-contact forces/torques and sensor offsets are subtracted from the force/torque measurements thus yielding the contact forces/torques. Experimental results show that both contact detection and force control performance are improved significantly by this approach.
Anthropometry of the eyelid and palpebral fissure in an Indian population.

BACKGROUND
The shapes of the eyebrow and upper eyelid are distinctive facial landmarks. In cosmetic and reconstructive procedures, maintenance of the anatomical relations of these landmarks ensures a pleasing postoperative appearance.


OBJECTIVES
The authors establish normal values for eyelid anthropometry in an Indian population.


METHOD
This prospective study included 216 patients between the ages of 16 and 60 years, divided into three groups by age (Groups A to C: 16 to 30 years, 31 to 45 years, 46 to 60 years, respectively) and sex. All patients were photographed from a frontal view, with measurements taken from these photographs. Parameters included the distance between the medial canthus and the lateral canthus (ie, the width of the palpebral fissure), the distance between the open upper eyelid margin and the lower eyelid margin, (ie, the vertical dimension of the palpebral fissure), the intercanthal distance, the interpupillary distance, and the height of the open upper lid. All measured values were analyzed by independent t-test.


RESULTS
There was a significant increase in palpebral fissure from Group B to Group C. A significant increase was also observed in intercanthal distance as age progressed beyond 45 years. There was a significant decrease in the interpupillary distance as age increased-from Group A to Group B and from Group B to Group C-and a similar increase in eyelid height in that age progression.


CONCLUSIONS
The anatomy of the Indian population is distinct in that the palpebral fissure in men is less than that in women. It appears that changes in the eye become more pronounced after 45 years, including an increase in palpebral fissure, intercanthal distance, and height of the upper lid, along with a decrease in interpupillary distance.
Resistance training concomitant to radiotherapy of spinal bone metastases – survival and prognostic factors of a randomized trial

PURPOSE
To compare the effects of resistance training versus passive physical therapy on bone survival in the metastatic bone during radiation therapy (RT) as combined treatment in patients with spinal bone metastases. Secondly, to evaluate overall survival and progression-free-survival (PFS) as well as to quantify prognostic factors of bone survival after combined treatment.


METHODS
In this randomized trial 60 patients were allocated from September 2011 until March 2013 into one of the two groups: resistance training (group A) or passive physical therapy (group B) with thirty patients in each group during RT. We estimated patient survival using Kaplan-Meier survival method. The Wald-test was used to evaluate the prognostic importance of pathological fracture, primary site, Karnofsky performance status, localization of metastases, number of metastases, and cerebral metastases.


RESULTS
Median follow-up was 10 months (range 2-35). Bone survival showed no significant difference between groups (p = .303). Additionally no difference between groups could be detected in overall survival (p = .688) and PFS (p = .295). Local bone progression was detected in 16.7 % in group B, no irradiated bone in group A showed a local progression over the course (p = 0.019). In univariate analysis breast cancer, prostate cancer, and the presence of cerebral metastases had a significant impact on bone survival in group B, while no impact could be demonstrated in group A.


CONCLUSIONS
In this group of patients with spinal bone metastases we were able to show that guided resistance training of the paravertebral muscles had no essential impact on survival concomitant to RT. Importantly, no local bone progression in group A was detected, nevertheless no prognostic factor for combined treatment could be evaluated.

Induction of depressed and elated mood by music influences the perception of facial emotional expressions in healthy subjects.

The judgement of healthy subject rating the emotional expressions of a set of schematic drawn faces is validated (study 1) to examine the relationship between mood (depressed/elated) and judgement of emotional expressions of these faces (study 2). Study 1: 30 healthy subjects judged 12 faces with respect to the emotions they express (fear, happiness, anger, sadness, disgust, surprise, rejection and invitation). It was found that a particular face could reflect various emotions. All eight emotions were reflected in the set of faces and the emotions were consensually judged. Moreover, gender differences in judgement could be established. Study 2: In a cross-over design, 24 healthy subjects judged the faces after listening to depressing or elating music. The faces were subdivided in six 'ambiguous' faces (i.e., expressing similar amounts of positive and negative emotions) and six 'clear' faces (i.e., faces showing a preponderance of positive or negative emotions). In addition, these two types of faces were distinguished with respect to the intensity of emotions they express. 11 subjects who showed substantial differences in experienced depression after listening to the music were selected for further analysis. It was found that, when feeling more depressed, the subjects perceived more rejection/sadness in ambiguous faces (displaying less intensive emotions) and less invitation/happiness in clear faces. In addition, subjects saw more fear in clear faces that express less intensive emotions. Hence, results show a depression-related negative bias in the perception of facial displays.
An Anti-Phishing mechanism for single sign-on based on QR-code

Today internet users use a single identity to access multiple services. With single sign-on (SSO), users don't have to remember separate username/password for each service provider, which helps the user to browse through the web seamlessly. SSO is however susceptible to phishing attacks. This paper describes a new anti phishing SSO model based on mobile QR code. Apart from preventing phishing attacks this new model is also safe against man in the middle & reply attacks.
Determination of 3D human body postures from a single view

In this paper a method is proposed to recover and interpret the 3D body structures of a person from a single view, provided that (1) at least six feature points on the head and a set of body joints are available on the image plane, and (2) the geometry of head and lengths of body segments formed by joints are known. First of all, the feature points on the head in the head-centered coordinate system and their image projections are used to determine a transformation matrix. Then, the camera position and orientations are extracted from the matrix. Finally, the 3D coordinates of the head points expressed in the camera-centered coordinate system are obtained. Starting from the coordinates of the neck, which is a head feature point, the 3D coordinates of other joints one-by-one are determined under the assumption of the fixed lengths of the body segments. A binary interpretation tree is used to represent the 2”-’ possible body structures, if a human body has n joints. To determine the final feasible body structures, physical and motion constraints are used to prune the interpretation tree. Formulas and rules required for the tree pruning are formulated. Experiments are used to illustrate the pruning powers of these constraints. In the two cases of input data chosen, a unique or nearly unique solution of the body structure is obtained. e 1985 Academic PI~SS, IIIC.
Suicidal ideation and school bullying experiences after controlling for depression and delinquency.

PURPOSE
This cross-sectional study examines differences in the frequency of suicidal ideation and suicidal behaviors across a group of verbal bullies, bully-victims, victims, physically aggressive bullies, and students not involved in bullying.


METHODS
A large sample of middle school students (n = 661; fifth through eighth grades; ages 10-13 years of age) completed a pencil-and-paper survey that included the University of Illinois Bully, Fight, and Victim scales. Students also self-reported how often they had thought of killing themselves or deliberating hurting themselves in past 6 months, and provided information about delinquent behaviors and symptoms of depression and anxiety.


RESULTS
We used cluster analysis to create bully-victim subtypes: uninvolved (n = 357), victims (n = 110), verbal bullies (n = 114), bully-victims (n = 29), and physically aggressive bullies (n = 42). Approximately 32%-38% of verbal bullies and victims, 60% of bully-victims, and 43% of physically aggressive bullies reported suicidal ideation, compared with 12% of uninvolved youth. Similarly, 24%-28% of verbal bullies and victims, 44% of bully-victims, and 35% of physically aggressive bullies reported deliberately trying to hurt or kill themselves, compared with 8% of uninvolved youth. Females in the bully-victim subtype reported particularly elevated suicidal ideation and behavior. After controlling for delinquency and depression, differences in suicidal thoughts and behaviors emerged only between uninvolved youth and the victim and bully-victim groups, but these differences were minimal.


CONCLUSIONS
Findings highlight that at a bivariate level, involvement in bullying in any capacity is linked to increased risk for suicidal ideation and behavior, and echoes previous literature documenting particularly strong mental health implications for bully-victims. Furthermore, this study points to the importance of considering delinquency and depression in conjunction with suicidal ideation and behaviors.
A survey on multistage/multiphase statistical modeling methods for batch processes

In industrial manufacturing, most batch processes are inherently multistage/multiphase in nature. To ensure both quality consistency of the manufactured products and safe operation of this kind of batch process, different multivariate statistical process control (MSPC) methods have been proposed in recent years. This paper gives an overview of multistage/multiphase statistical process control methods used for process analysis, monitoring, quality prediction and online quality improvement. Different types of phase divisions and modeling strategies are introduced and the method properties are discussed. For comparisons, a selection guide to these methods for different application purposes is provided. Finally, some promising research directions are suggested based on existing works. 2009 Elsevier Ltd. All rights reserved.

Engineering JIAC Multi-Agent Systems (Demonstration)

The development of high quality software is considered to be extremely di cult. In fact, it has been argued that such endeavours are one of the most di cult construction tasks that humans undertake [2]. Contemporary IT-infrastructures facilitate the need for distributed applications—a system design which can be implemented with Agent Oriented Software Engineering [2]. Yet, despite the requirement for distributed systems and despite the availability of frameworks, methodologies and tool suites that support the development of distributed applications, there are only few attempts to use agent technology for commercial or industrial applications. The reasons for this are not entirely clear, though, analyses [6, 7, 9] show that there are several factors that may foster industrial adoption of agent technology. These factors include: awareness for the need for agent technology, compliance with standards, reasonable costs, scalability and performance, stability and robustness, extensibility, mature methodologies and tool support, and a comprehensive user documentation. To facilitate the industrial adoption of agent technology, we developed the Java Intelligent Agent Componentware, or JIAC [4]. JIAC supports a comprehensive set of standards, ensures reliable applications, supports custom extensions, and provides a whole set of user friendly and well documented tools for the design, implementation, deployment, and monitoring of multi-agent systems. Agent frameworks with a focus on industrial requirements, however, find it difficult to gain foothold in the realm of research where other factors determine their level of acceptance. The aim of JIAC is to show that industrial requirements and research needs can be combined in one solution.
Stronger evidence for small fiber sensory neuropathy in restless genital syndrome: two case reports in males.

INTRODUCTION
Restless genital syndrome (ReGS) is characterized by unwanted, unpleasant genital sensations, restless legs, and/or overactive bladder, as well as neuropathy of the dorsal nerve of the clitoris. So far, ReGS has only been reported in females.


AIM
To report the occurrence of ReGS in two males.


METHODS
Two males with unwanted genital sensations presented in our clinic. In-depth interview, routine and hormonal investigations, electro-encephalography, magnetic resonance imaging of brain and pelvis, manual examination of the pubic bone, and sensory testing of genital dermatomes were performed. In both males, conventional transcutaneous electrical nerve stimulation was applied bilaterally at the pudendal dermatome.


MAIN OUTCOME MEASURES
Oral report, questionnaire on frequency and intensity of restless genital feelings, restless legs, overactive bladder, and satisfaction with the transcutaneous electrical nerve stimulation (TENS) treatment.


RESULTS
ReGS in a 74-year-old male manifested as unpleasant genital sensations of being on the edge of an orgasm with overactive bladder, in the absence of erection and ejaculation. Genital sensory testing elicited bilateral points of static mechanical hyperesthesia in the pudendal dermatome. Manual examination of the dorsal nerve of the penis (DNP) elicited the genital sensations. TENS application resulted in a 90% reduction of genital sensations and complaints of overactive bladder syndrome (OAB). ReGS in a 38-year-old male manifested as unwanted and unpleasant spontaneous ejaculations and complaints of OAB. Genital sensory testing elicited bilateral points of static mechanical hyperesthesia in the pudendal dermatome. Manual examination of the DNP elicited the genital sensations. TENS application had no effect on genital complaints and complaints of OAB.


CONCLUSIONS
ReGS is not a typical female disorder as it also affects males. This notion and the finding of typical sensory abnormalities of the genital end branches of the pudendal nerve in males and females--as previously reported--provides strong evidence for Small Fiber Sensory Neuropathy as a common cause of ReGS.
A randomized controlled trial of brief interventions for problem gambling in substance abuse treatment patients.

OBJECTIVE
This study evaluated the efficacy of brief gambling treatments in patients attending substance abuse treatment clinics.


METHOD
Substance abuse treatment patients with gambling problems (N = 217) were randomly assigned to a 10- to 15-min brief psychoeducation gambling intervention; a 10- to 15-min brief advice intervention addressing gambling norms, risk factors, and methods to prevent additional problems; or 4 50-min sessions of motivational enhancement therapy plus cognitive behavior therapy for reducing gambling (MET + CBT). Gambling and related problems were assessed at baseline and throughout 24 months.


RESULTS
In the sample as a whole, days and dollars wagered and gambling problems decreased markedly from baseline through Month 5; thereafter, reductions in dollars wagered and gambling problems continued to decrease modestly but significantly, and days gambled remained constant. Brief advice significantly reduced days gambled between baseline and Month 5 relative to brief psychoeducation. The MET + CBT condition engendered no benefit beyond brief advice in terms of days gambled but did lead to more precipitous reductions in dollars gambled and problems experienced in the initial 5 months, and greater clinically significant improvements in gambling in both the short and long term. MET + CBT also resulted in initial decreases in self-reported alcohol use and problems but did not differentially impact self-reported illicit drug use or submission of positive samples.


CONCLUSIONS
Gambling problems tend to dissipate over time regardless of the intervention applied, but offering MET + CBT was more efficacious in decreasing gambling than providing a brief single session intervention. (PsycINFO Database Record

Alterations in anatomic and functional imaging parameters with repeated FDG PET-CT and MRI during radiotherapy for head and neck cancer: a pilot study

The use of imaging to implement on-treatment adaptation of radiotherapy is a promising paradigm but current data on imaging changes during radiotherapy is limited. This is a hypothesis-generating pilot study to examine the changes on multi-modality anatomic and functional imaging during (chemo)radiotherapy treatment for head and neck squamous cell carcinoma (HNSCC). Eight patients with locally advanced HNSCC underwent imaging including computed tomography (CT), Fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT and magnetic resonance imaging (MRI) (including diffusion weighted (DW) and dynamic contrast enhanced (DCE)) at baseline and during (chemo)radiotherapy treatment (after fractions 11 and 21). Regions of interest (ROI) were drawn around the primary tumour at baseline and during treatment. Imaging parameters included gross tumour volume (GTV) assessment, SUVmax, mean ADC value and DCE-MRI parameters including Plasma Flow (PF). On treatment changes and correlations between these parameters were analysed using a Wilcoxon rank sum test and Pearson’s linear correlation coefficient respectively. A p-value <0.05 was considered statistically significant. Statistically significant reductions in GTV-CT, GTV-MRI and GTV-DW were observed between all imaging timepoints during radiotherapy. Changes in GTV-PET during radiotherapy were heterogeneous and non-significant. Significant changes in SUVmax, mean ADC value, Plasma Flow and Plasma Volume were observed between the baseline and the fraction 11 timepoint, whilst only changes in SUVmax between baseline and the fraction 21 timepoint were statistically significant. Significant correlations were observed between multiple imaging parameters, both anatomical and functional; 20 correlations between baseline to the fraction 11 timepoint; 12 correlations between baseline and the fraction 21 timepoints; and 4 correlations between the fraction 11 and fraction 21 timepoints. Multi-modality imaging during radiotherapy treatment demonstrates early changes (by fraction 11) in both anatomic and functional imaging parameters. All functional imaging modalities are potentially complementary and should be considered in combination to provide multi-parametric tumour assessment, to guide potential treatment adaptation strategies.
