    Full Text Available Abstract Objective To present the design, methods, and rationale of the Child/Adolescent Anxiety Multimodal Study (CAMS, a recently completed federally-funded, multi-site, randomized placebo-controlled trial that examined the relative efficacy of cognitive-behavior therapy (CBT, sertraline (SRT, and their combination (COMB against pill placebo (PBO for the treatment of separation anxiety disorder (SAD, generalized anxiety disorder (GAD and social phobia (SoP in children and adolescents. Methods Following a brief review of the acute outcomes of the CAMS trial, as well as the psychosocial and pharmacologic treatment literature for pediatric anxiety disorders, the design and methods of the CAMS trial are described. Results CAMS was a six-year, six-site, randomized controlled trial. Four hundred eighty-eight (N = 488 children and adolescents (ages 7-17 years with DSM-IV-TR diagnoses of SAD, GAD, or SoP were randomly assigned to one of four treatment conditions: CBT, SRT, COMB, or PBO. Assessments of anxiety symptoms, safety, and functional outcomes, as well as putative mediators and moderators of treatment response were completed in a multi-measure, multi-informant fashion. Manual-based therapies, trained clinicians and independent evaluators were used to ensure treatment and assessment fidelity. A multi-layered administrative structure with representation from all sites facilitated cross-site coordination of the entire trial, study protocols and quality assurance. Conclusions CAMS offers a model for clinical trials methods applicable to psychosocial and psychopharmacological comparative treatment trials by using state-of-the-art methods and rigorous cross-site quality controls. CAMS also provided a large-scale examination of the relative and combined efficacy and safety of the best evidenced-based psychosocial (CBT and pharmacologic (SSRI treatments to date for the most commonly occurring pediatric anxiety disorders.

    Music therapy has been shown to be effective for children with psychopathology, providing an alternative nonverbal approach to the treatment of children with anxiety disorders. This pilot study investigates the efficacy of Multimodal Music Therapy (MMT), a combination of music therapy and cognitive-behavioral therapy, compared to treatment as usual (TAU). Thirty-six children aged 8-12 years with a primary diagnosis of an anxiety disorder were randomly assigned to 15 sessions of MMT or to TAU. Diagnostic status and dimensional outcome variables were assessed at the end of treatment and 4 months later. MMT was superior compared to TAU according to the remission rates after treatment (MMT 67%; TAU 33%; chi2 = 4.0; p = 0.046) and remissions persisted until four months post-treatment. Dimensional measures showed equivalent improvement after either MMT or TAU. The results regarding the efficacy of MMT are promising for children with anxiety disorders. Further evaluation with larger samples and comparisons to pure CBT are recommended.

    Anxiety is common among adolescents with autism spectrum disorders (ASD) and may amplify the core social disability, thus necessitating combined treatment approaches. This pilot, randomized controlled trial (RCT) evaluated the feasibility and preliminary outcomes of the Multimodal Anxiety and Social Skills Intervention (MASSI) program in a sample of 30 adolescents with ASD and anxiety symptoms of moderate or greater severity. The treatment was acceptable to families, subject adherence was high, and therapist fidelity was high. A 16% improvement in ASD social impairment (within-group effect size = 1.18) was observed on a parent-reported scale. Although anxiety symptoms declined by 26%, the change was not statistically significant. These findings suggest MASSI is a feasible treatment program and further evaluation is warranted.

    Family accommodation is associated with a range of clinical features including symptom severity, functional impairment, and treatment response. However, most previous studies in children and adolescents investigated family accommodation in samples of youth with obsessive-compulsive disorder (OCD) or anxiety disorders receiving non-intensive outpatient services. In this study, we aimed to investigate family accommodation of anxiety symptoms in a sample of youth with clinical anxiety levels undergoing an intensive multimodal intervention for anxiety disorders or OCD. We first assessed the internal consistency of the Family Accommodation Scale - Anxiety (FASA). We next examined family accommodation presentation and correlates. The FASA showed high internal consistency for all subscales and total score, and good item and subscale correlations with the total score. All parents reported at least mild accommodation, and the mean levels of family accommodation were particularly high. Child age, anxiety severity, and comorbid depressive symptoms predicted baseline accommodation. However, the association between anxiety severity and family accommodation no longer remained significant after adding the other factors to the model. In addition, family accommodation partially mediated the relationship between anxiety severity and functional impairment. Finally, post-treatment changes in family accommodation predicted changes in symptom severity and functional impairment. These findings suggest the FASA is an appropriate tool to assess family accommodation in intensive treatment samples. Further, they underline the importance of addressing family accommodation in this population given the particularly high levels of accommodating behaviors and the evidence for adverse outcomes associated with this feature.

    Objective The aim of the study was to examine the effectiveness of an intensive inpatient three-week multimodal therapy. We focused especially on the impact on the multimodal therapy outcome of the pre-admission number of treatment types patients had received and of medical specialist groups patients had consulted. Methods 155 patients with chronic low back pain and indication for multimodal therapy were evaluated with respect to pain intensity, depression, anxiety, well-being, and pre-admission health care utilization. In our controlled clinical trial we compared N = 66 patients on the waiting list with N = 89 patients who received immediate treatment. The waiting list patients likewise attended multimodal therapy after the waiting period. Longitudinal post-treatment data for both were collected at three- and twelve-month follow-ups. The impact of pre-admission health care utilization on multimodal therapy outcome (post) was analysed by structural equation model. Results Compared to the control group, multimodal therapy patients’ pain intensity and psychological variables were significantly reduced. Longitudinal effects with respect to pre-measures were significant at three-month follow-up for pain intensity (ES = -0.48), well-being (ES = 0.78), anxiety (ES = -0.33), and depression (ES = -0.30). Effect sizes at twelve-month follow-up were small for anxiety (ES = -0.22), and moderate for general well-being (ES = 0.61). Structural equation model revealed that a higher number of pre-admission treatment types was associated with poorer post-treatment outcomes in pain intensity, well-being, and depression. Conclusion Multimodal therapy proved to be effective with regard to improvements in pain intensity, depression, anxiety, and well-being. The association between treatment effect and number of pre-admission pain treatment types suggests that patients would benefit more from attending multimodal therapy in an earlier stage of health care.

    Here, we report on findings from a 15-month follow-up of a school-based program called Empowering a Multimodal Pathway Toward Healthy Youth (EMPATHY). This was primarily intended to reduce suicidal thinking in pre-teens, adolescents, and youth students aged 11–18 in middle schools (Grades 6–8) and high SCHOOLS (Grades 9–12). It also aimed to reduce depression and anxiety. The EMPATHY multimodal program consisted of repeated data collection, identification of a high-risk group, a rapid intervention for this high-risk group including offering supervised online cognitive behavioral therapy (CBT) program, a universal CBT intervention for those in Grades 6–8, a variety of interactions with trained staff (“Resiliency Coaches”), and referral to external medical and psychiatric services where appropriate. There were four time-points at which assessments were made: baseline, 3, 7, and 15 months. Here, we report cross-sectional findings over 15 months in a total of 6,227 students who were assessed at least once during the study period. Additionally, we report longitudinal findings from the 1,884 students who completed all 4 assessments. Our results found highly statistically significant decreases in suicidality rates, with the percentage of the total school population who were actively suicidal decreasing from 4.4% at baseline (n = 143 of 3,244) to 2.8% at 15 months (n = 125 of 4,496) (p < 0.001). There were also highly statistically significant reductions in depression and anxiety scores at each time-point. Thus, Mean Depression scores at baseline for the entire student population were 3.73 ± 3.87 (n = 3,244) at baseline and decreased to 3.22 ± 3.52 (n = 4,496) (p < 0.001). Since most students were not depressed, whole population changes such as this may indicate impact in many areas. In the longitudinal analysis of students who completed all four assessments, there were also highly statistically significant improvements

    Functional improvement in bipolar and schizophrenic patients is one of the main aims of treatment. Nevertheless, there is no evidence about the effect of socio-occupational intervention within a multimodal intervention (MI) programme. To describe the socio-occupational profile and to evaluate the functional effect of a MI in bipolar I and schizophrenic patients. A prospective, longitudinal, therapeutic-comparative study was performed including 302 subjects (104 schizophrenic and 198 Bipolar Disorder I [BDI] patients), who were randomised into two groups, multimodal (psychiatry, psychology, medicine, occupational therapy, neuropsychology, and family therapy), or traditional intervention (psychiatry and medicine only). Several scales were applied to assess assertiveness, free time management, social abilities, general anxiety, self-care and performance in home, work and community tasks. After performing the longitudinal analysis, it was shown that the multimodal intervention was more effective than traditional intervention in general anxiety scores (P=.026) and development in home tasks (P=.03) in schizophrenic patients. No statistical differences were found in bipolar patients. The other variables showed improvement, however, their effect was similar in both intervention groups. Our study identified functional improvement in home tasks in schizophrenic patients after receiving multimodal intervention. Other variables also showed improvement for both interventions groups. Future studies, applying longer rehabilitation programs and other ecological strategies should be performed to identify the most effective interventions.

    The objective of this study was to examine whether participation in a 12-month multimodal intervention would improve mood and cognitive function in adults with progressive multiple sclerosis (MS). In this one-arm, open-label feasibility trial, participants were prescribed a home-based multimodal intervention, including (1) a modified Paleolithic diet; (2) an exercise program (stretching and strengthening of the trunk and lower limb muscles); (3) neuromuscular electrical stimulation (EStim) of trunk and lower limb muscles; and (4) stress management (meditation and self-massage). Individuals completed measures of mood (Beck Anxiety and Depression Inventories) and cognitive (Cognitive Stability Index, Cognitive Screening Test, Delis-Kaplan Executive Function System) and executive function (Wechsler Adult Intelligence Scale) at baseline and 3, 6, 9, and 12 months after the start of the intervention. Dosage of the multimodal intervention was assessed at 3, 6, 9, and 12 months. The more individuals participated in the intervention activities, the greater improvements they had from baseline to 12 months on self-report measures of anxiety (Beck Anxiety Inventory [BAI]; ps = 0.001 to 0.02), depression (Beck Depression Inventory [BDI]; ps = Mood and cognitive improvements were more closely related to a higher intake of the modified Paleolithic diet than to exercise and stress management dosage. Anxiety and depression changes were evident after just a few months, whereas changes in cognitive function were generally not observed until later in the intervention period. Mood and cognitive function changes from baseline to 12 months were significantly associated with fatigue improvements (ps = exercise, EStim, and stress management intervention like this one has the potential to improve the mood and cognitive symptoms that can lead to considerable suffering in people with MS, potentially improving quality of life and function for people with progressive MS.

    IMPORTANCE Pediatric anxiety disorders are highly prevalent and impairing and are considered gateway disorders in that they predict adult psychiatric problems. Although they can be effectively treated in the short term, data are limited on the long-term outcomes in treated children and adolescents, particularly those treated with medication. OBJECTIVE To determine whether acute clinical improvement and treatment type (ie, cognitive behavioral therapy, medication, or their combination) predicted remission of anxiety and improvement in global functioning at a mean of 6 years after randomization and to examine predictors of outcomes at follow-up. DESIGN, SETTING, AND PARTICIPANTS This naturalistic follow-up study, as part of the Child/Adolescent Anxiety Multimodal Extended Long-term Study (CAMELS), was conducted at 6 academic sites in the United States and included 288 youths (age range, 11–26 years; mean age, 17 years). Youths were randomized to 1 of 4 interventions (cognitive behavioral therapy, medication, combination, or pill placebo) in the Child/Adolescent Anxiety Multimodal Study (CAMS) and were evaluated a mean of 6 years after randomization. Participants in this study constituted 59.0% of the original CAMS sample. EXPOSURES Participants were assessed by independent evaluators using a semistructured diagnostic interview to determine the presence of anxiety disorders, the severity of anxiety, and global functioning. Participants and their parents completed questionnaires about mental health symptoms, family functioning, life events, and mental health service use. MAIN OUTCOMES AND MEASURES Remission, defined as the absence of all study entry anxiety disorders. RESULTS Almost half of the sample (46.5%) were in remission a mean of 6 years after randomization. Responders to acute treatment were significantly more likely to be in remission (odds ratio, 1.83; 95% CI, 1.08–3.09) and had less severe anxiety symptoms and higher functioning; the assigned treatment

    Generalized anxiety disorder (GAD) is difficult to recognize and hard to separate from major depression (MD) in clinical settings. Biomarkers might support diagnostic decisions. This study used machine learning on multimodal biobehavioral data from a sample of GAD, MD and healthy subjects to differentiate subjects with a disorder from healthy subjects (case-classification) and to differentiate GAD from MD (disorder-classification). Subjects with GAD ( n  = 19), MD without GAD ( n  = 14), and healthy comparison subjects ( n  = 24) were included. The sample was matched regarding age, sex, handedness and education and free of psychopharmacological medication. Binary support vector machines were used within a nested leave-one-out cross-validation framework. Clinical questionnaires, cortisol release, gray matter (GM), and white matter (WM) volumes were used as input data separately and in combination. Questionnaire data were well-suited for case-classification but not disorder-classification (accuracies: 96.40%, p   .22). The opposite pattern was found for imaging data (case-classification GM/WM: 58.71%, p  = .09/43.18%, p  > .66; disorder-classification GM/WM: 68.05%, p  = .034/58.27%, p  > .15) and for cortisol data (38.02%, p  = .84; 74.60%, p  = .009). All data combined achieved 90.10% accuracy ( p  < .001) for case-classification and 67.46% accuracy ( p  = .0268) for disorder-classification. In line with previous evidence, classification of GAD was difficult using clinical questionnaire data alone. Particularly cortisol and GM volume data were able to provide incremental value for the classification of GAD. Findings suggest that neurobiological biomarkers are a useful target for further research to delineate their potential contribution to diagnostic processes.

    The use of digital medical imaging systems in healthcare institutions has increased significantly, and the large amounts of data in these systems have led to the conception of powerful support tools: recent studies on content-based image retrieval (CBIR) and multimodal information retrieval in the field hold great potential in decision support, as well as for addressing multiple challenges in healthcare systems, such as computer-aided diagnosis (CAD). However, the subject is still under heavy research, and very few solutions have become part of Picture Archiving and Communication Systems (PACS) in hospitals and clinics. This paper proposes an extensible platform for multimodal medical image retrieval, integrated in an open-source PACS software with profile-based CBIR capabilities. In this article, we detail a technical approach to the problem by describing its main architecture and each sub-component, as well as the available web interfaces and the multimodal query techniques applied. Finally, we assess our implementation of the engine with computational performance benchmarks.

    We developed a portable multimodal system with seven different mechanisms of pain relief incorporated into a lumbar belt called the Comfort-N-Harmony Belt (C&H belt). Here, we describe the technical details of the system and also summarize the effects of this multimodal pain relieving technology as an adjuvant to analgesics versus analgesics alone, on the level of pain, improvement of psychological status, disability, and the quality of life in the patients with neuropathic low back pain (LBP). We tracked the volunteers who were following up at a tertiary health care center for the complaints of neuropathic LBP of minimum three months duration and were on analgesics alone with no relief in the severity of the pain. Study group A (n = 45) consisted of volunteers with LBP on C&H belt therapy, along with the usually prescribed analgesic intake, and group B (n = 45) with LBP volunteers on analgesics, plus a similar looking but plain leather belt (placebo). For pain, the VAS (Visual Analogue Scale); for anxiety and depression, the (HADS) Hospital Anxiety-Depression Scale; for disability, the RMDQ (Roland Morris Disability Questionnaire); and for quality of life, (NHP) Nottingham-Health-Profile were used before and after the study period.  There were no significant differences in demographic variables between the groups (p improved compared to the pre-treatment scores (p improvements in the scores of NHP-energy level and NHP-social isolation (p 0.05). However, in comparison of pre- and post-treatment scores, the pre-treatment score values of RMDQ, NHP-pain, NHP-physical activity, and NHP-social isolation were much higher in group A compared to the group B, but still these scores were, in a statistically significant manner, improved in group A compared to the group B after the study period was over (p improving function and quality of life, and help in relieving the associated anxiety and depression in patients with chronic neuropathic LBP than the analgesics alone

    It is widely recognised that there are associations between headache, psychiatric comorbidity and attachment insecurity in both adults and children. The aims of this study were: 1) to compare perceived attachment security and anxiety in children and adolescents with migraine without aura and a healthy control group; 2) to test whether the child's perceived security of attachment to the mother and the father mediated the association between migraine and anxiety. One hundred children and adolescents with Migraine without Aura were compared with a control group of 100 children without headache. The Security Scale (measures perceived security of attachments) and the Self-Administered Psychiatric Scales for Children and Adolescents, a measure of anxiety symptoms, were administered to all participants. The clinical group had lower attachment security than the control group and higher scores on all anxiety scales. Anxiety was negatively correlated with attachment. Children's attachment to their mother mediated the increase in global anxiety in the clinical group. Insecure paternal attachment was associated with greater insecurity in maternal attachment, suggesting that there is a complex pathway from migraine to anxiety symptoms mediated by perceived insecurity of paternal attachment and hence also by perceived insecurity of maternal attachment. These results suggest that insecure parental attachment may exacerbate anxiety in children and adolescents with migraine and point to the importance of multimodal interventions, perhaps taking account of family relationships, for children and adolescents with migraine.

    Despite the well-documented gender effect in anxiety, less is known about contributing factors to women's greater risk for anxiety and fears. The present study examined the relationship between gender, gender role orientation (i.e., expressivity/instrumentality) and fear of harmless insects (tarantula), using a multimodal approach of self-report measures, a Behavioral Approach Test (BAT), and physiological reactivity. Participants (144 college students; 67 women, 77 men) completed a questionnaire packet and then were instructed to approach a tarantula. We were unable to replicate Pierce and Kirkpatrick's (1992) findings that men underreport anxiety. Consistent with the literature, women in the study experienced greater anxiety and avoidance compared to men. However, men and women did not differ on physiological reactivity during the first 2 min of the BAT. The concordance across avoidance, anxiety and heart rate reactivity differed by gender, suggesting that men and women have different experiences when faced with a fearful object. Furthermore, instrumentality (masculinity) was negatively related to anticipatory anxiety for women but not for men. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Chronic pain has high prevalence rates and is one of the top causes of years lived with disability. The aim of the present study was to evaluate the long-term effects of a multimodal day-clinic treatment for chronic pain. The sample included 183 chronic pain patients (114 females and 69 males; 53.3 ± 9.8 years who participated in a four-week multimodal day-clinic treatment for chronic pain. The patients’ average current pain intensity (NRS, sensory and affective pain (Pain Perception Scale, and depression and anxiety (HADS were assessed at pre- and posttreatment, as well as at three follow-ups (one month, six months, and twelve months after completion of the treatment. Multilevel models for discontinuous change were performed to evaluate the change of the outcome variables. Improvements from pretreatment to posttreatment and from pretreatment to all follow-ups emerged for pain intensity (NRS; 0.54 ≤ d ≤ 0.74, affective pain (Pain Perception Scale; 0.24 ≤ d ≤ 0.47, depression (HADS; 0.38 ≤ d ≤ 0.53, and anxiety (HADS; 0.26 ≤ d ≤ 0.43 (all p<0.05. Sensory pain as assessed with the Pain Perception Scale did not show any significant change. Patients suffering from chronic pain benefited from the multimodal pain treatment up to twelve months after completion of the treatment.

  8. A multimodal parallel architecture: A cognitive framework for multimodal interactions.

    2016-01-01

    Human communication is naturally multimodal, and substantial focus has examined the semantic correspondences in speech-gesture and text-image relationships. However, visual narratives, like those in comics, provide an interesting challenge to multimodal communication because the words and/or images can guide the overall meaning, and both modalities can appear in complicated "grammatical" sequences: sentences use a syntactic structure and sequential images use a narrative structure. These dual structures create complexity beyond those typically addressed by theories of multimodality where only a single form uses combinatorial structure, and also poses challenges for models of the linguistic system that focus on single modalities. This paper outlines a broad theoretical framework for multimodal interactions by expanding on Jackendoff's (2002) parallel architecture for language. Multimodal interactions are characterized in terms of their component cognitive structures: whether a particular modality (verbal, bodily, visual) is present, whether it uses a grammatical structure (syntax, narrative), and whether it "dominates" the semantics of the overall expression. Altogether, this approach integrates multimodal interactions into an existing framework of language and cognition, and characterizes interactions between varying complexity in the verbal, bodily, and graphic domains. The resulting theoretical model presents an expanded consideration of the boundaries of the "linguistic" system and its involvement in multimodal interactions, with a framework that can benefit research on corpus analyses, experimentation, and the educational benefits of multimodality.

    Full Text Available This study was designed to investigate the impact of multimodal text on reading comprehension test performance of Iranian intermediate learners. A total of 80 students participated in this study. All of them were Iranian female EFL learners with the age ranging from 16 to 18. They were selected from a boarding high school in Nasr Abad, Torbat Jam in Khorasan e Razavi, Iran. The students were randomly settled in four groups, who received different instructional approaches through using linear texts, multimodal printed texts, non-printed multimodal texts, and both multimodal printed and non-printed texts.  A pre-test and post-test were used to find out the differences before and after the experimental treatment.  The results reflected that the printed and non-printed multimodal texts had significant impact on reading comprehension test performance. In contrast, applying linear texts or traditional texts did not exert significant influence on reading comprehension ability of the participants. The findings provide useful hints for language instructors to improve effectiveness of instructional reading curriculums and reading ability of language learners. The participants who learned reading comprehension through using multimodal printed and non-printed texts enjoy reading programs and develop their intrinsic and extrinsic motivation for improving reading ability.

    Greater parent-youth disagreement on youth symptomatology is associated with a host of factors (e.g., parental psychopathology, family functioning) that might impede treatment. Parent-youth disagreement may represent an indicator of treatment prognosis. Using data from the Child/Adolescent Anxiety Multimodal Study, this study used polynomial regression and longitudinal growth modeling to examine whether parent-youth agreement prior to and throughout treatment predicted treatment outcomes (anxiety severity, youth functioning, responder status, and diagnostic remission, rated by an independent evaluator). When parents reported more symptoms than youth prior to treatment, youth were less likely to be diagnosis-free post-treatment; this was only true if the youth received cognitive-behavioral therapy (CBT) alone, not if youth received medication, combination, or placebo treatment. Increasing concordance between parents and youth over the course of treatment was associated with better treatment outcomes across all outcome measures ( ps < .001). How parents and youth "co-report" appears to be an indicator of CBT outcome. Clinical implications and future directions are discussed.

    2011-07-01

    Full Text Available Abstract Background Appropriate management of anxiety disorders in primary care requires clinical assessment and monitoring of the severity of the anxiety. This study focuses on the Beck Anxiety Inventory (BAI as a severity indicator for anxiety in primary care patients with different anxiety disorders (social phobia, panic disorder with or without agoraphobia, agoraphobia or generalized anxiety disorder, depressive disorders or no disorder (controls. Methods Participants were 1601 primary care patients participating in the Netherlands Study of Depression and Anxiety (NESDA. Regression analyses were used to compare the mean BAI scores of the different diagnostic groups and to correct for age and gender. Results Patients with any anxiety disorder had a significantly higher mean score than the controls. A significantly higher score was found for patients with panic disorder and agoraphobia compared to patients with agoraphobia only or social phobia only. BAI scores in patients with an anxiety disorder with a co-morbid anxiety disorder and in patients with an anxiety disorder with a co-morbid depressive disorder were significantly higher than BAI scores in patients with an anxiety disorder alone or patients with a depressive disorder alone. Depressed and anxious patients did not differ significantly in their mean scores. Conclusions The results suggest that the BAI may be used as a severity indicator of anxiety in primary care patients with different anxiety disorders. However, because the instrument seems to reflect the severity of depression as well, it is not a suitable instrument to discriminate between anxiety and depression in a primary care population.

    Objective: To analyze multimodal magnetic nanoparticles-Rhodamine B in culture media for cell labeling, and to establish a study of multimodal magnetic nanoparticles-Rhodamine B detection at labeled cells evaluating they viability at concentrations of 10 μg Fe/mL and 100μg Fe/mL. Methods: We performed the analysis of stability of multimodal magnetic nanoparticles-Rhodamine B in different culture media; the mesenchymal stem cells labeling with multimodal magnetic nanoparticles-Rhodamine B; the intracellular detection of multimodal magnetic nanoparticles-Rhodamine B in mesenchymal stem cells, and assessment of the viability of labeled cells by kinetic proliferation. Results: The stability analysis showed that multimodal magnetic nanoparticles-Rhodamine B had good stability in cultured Dulbecco's Modified Eagle's-Low Glucose medium and RPMI 1640 medium. The mesenchymal stem cell with multimodal magnetic nanoparticles-Rhodamine B described location of intracellular nanoparticles, which were shown as blue granules co-localized in fluorescent clusters, thus characterizing magnetic and fluorescent properties of multimodal magnetic nanoparticles Rhodamine B. Conclusion: The stability of multimodal magnetic nanoparticles-Rhodamine B found in cultured Dulbecco's Modified Eagle's-Low Glucose medium and RPMI 1640 medium assured intracellular mesenchymal stem cells labeling. This cell labeling did not affect viability of labeled mesenchymal stem cells since they continued to proliferate for five days. (author)

    2017-01-01

    This research assessed the feasibility of Social Communication Anxiety Treatment (S-CAT) developed by Elisa Shipon-Blum, a brief multimodal approach, to increase social communication in 40 children aged 5-12 years with selective mutism (SM). SM is a disorder in which children consistently fail to speak in specific situations although they have the ability to do so. Key features of this approach are the SM-Social Communication Comfort Scale (SCCS), transfer of control (ToC), a nonchalant therapeutic style, and cognitive-behavioral strategies over a brief time frame. Following 9 weeks of treatment, children showed significant gains in speaking frequency on all 17 items from the Selective Mutism Questionnaire (SMQ), a standardized measure of SM severity. Children also showed decreased levels of anxiety and withdrawal as reported by parents on the Child Behavior Checklist (CBCL). SM initial symptom severity and family therapy compliance, but not duration of SM, contributed to treatment outcomes.

  17. Multimodality Registration without a Dedicated Multimodality Scanner

    Directory of Open Access Journals (Sweden)

    Bradley J. Beattie

    2007-03-01

    Full Text Available Multimodality scanners that allow the acquisition of both functional and structural image sets on a single system have recently become available for animal research use. Although the resultant registered functional/structural image sets can greatly enhance the interpretability of the functional data, the cost of multimodality systems can be prohibitive, and they are often limited to two modalities, which generally do not include magnetic resonance imaging. Using a thin plastic wrap to immobilize and fix a mouse or other small animal atop a removable bed, we are able to calculate registrations between all combinations of four different small animal imaging scanners (positron emission tomography, single-photon emission computed tomography, magnetic resonance, and computed tomography [CT] at our disposal, effectively equivalent to a quadruple-modality scanner. A comparison of serially acquired CT images, with intervening acquisitions on other scanners, demonstrates the ability of the proposed procedures to maintain the rigidity of an anesthetized mouse during transport between scanners. Movement of the bony structures of the mouse was estimated to be 0.62 mm. Soft tissue movement was predominantly the result of the filling (or emptying of the urinary bladder and thus largely constrained to this region. Phantom studies estimate the registration errors for all registration types to be less than 0.5 mm. Functional images using tracers targeted to known structures verify the accuracy of the functional to structural registrations. The procedures are easy to perform and produce robust and accurate results that rival those of dedicated multimodality scanners, but with more flexible registration combinations and while avoiding the expense and redundancy of multimodality systems.

    2010-01-01

    In multimodality imaging, the need to combine morphofunctional information can be approached by either acquiring images at different times (asynchronous), and fused them through digital image manipulation techniques or simultaneously acquiring images (synchronous) and merging them automatically. The asynchronous post-processing solution presents various constraints, mainly conditioned by the different positioning of the patient in the two scans acquired at different times in separated machines. The best solution to achieve consistency in time and space is obtained by the synchronous image acquisition. There are many multimodal technologies in molecular imaging. In this review we will focus on those multimodality image techniques more commonly used in the field of diagnostic imaging (SPECT-CT, PET-CT) and new developments (as PET-MR). The technological innovations and development of new tracers and smart probes are the main key points that will condition multimodality image and diagnostic imaging professionals' future. Although SPECT-CT and PET-CT are standard in most clinical scenarios, MR imaging has some advantages, providing excellent soft-tissue contrast and multidimensional functional, structural and morphological information. The next frontier is to develop efficient detectors and electronics systems capable of detecting two modality signals at the same time. Not only PET-MR but also MR-US or optic-PET will be introduced in clinical scenarios. Even more, MR diffusion-weighted, pharmacokinetic imaging, spectroscopy or functional BOLD imaging will merge with PET tracers to further increase molecular imaging as a relevant medical discipline. Multimodality imaging techniques will play a leading role in relevant clinical applications. The development of new diagnostic imaging research areas, mainly in the field of oncology, cardiology and neuropsychiatry, will impact the way medicine is performed today. Both clinical and experimental multimodality studies, in

    Background To examine (1) changes in parent (global psychological distress, trait anxiety) and family (dysfunction, burden) functioning following 12 weeks of child-focused anxiety treatment, and (2) whether changes in these parent and family factors were associated with child's treatment condition and response. Methods Participants were 488 youth ages 7–17 years (50% female; mean age 10.7 years) who met DSM-IV-TR criteria for social phobia, separation anxiety, and/or generalized anxiety disorder, and their parents. Youth were randomly assigned to 12 weeks of “Coping Cat” individual cognitive-behavioral therapy (CBT), medication management with sertraline (SRT), their combination (COMB), or medication management with pill placebo (PBO) within the multisite Child/Adolescent Anxiety Multimodal Study (CAMS). At pre- and posttreatment, parents completed measures of trait anxiety, psychological distress, family functioning, and burden of child illness; children completed a measure of family functioning. Blinded independent evaluators rated child's response to treatment using the Clinical Global Impression-Improvement Scale at posttreatment. Results Analyses of covariance revealed that parental psychological distress and trait anxiety, and parent-reported family dysfunction improved only for parents of children who were rated as treatment responders, and these changes were unrelated to treatment condition. Family burden and child-reported family dysfunction improved significantly from pre- to posttreatment regardless of treatment condition or response. Conclusions Findings suggest that child-focused anxiety treatments, regardless of intervention condition, can result in improvements in nontargeted parent symptoms and family functioning particularly when children respond successfully to the treatment.

    2018-06-01

    Low-carbon environmental protection is the focus of attention around the world, scientists are constantly researching on production of carbon emissions and living carbon emissions. However, there is little literature about multimodal transportation based on carbon emission at home and abroad. Firstly, this paper introduces the theory of multimodal transportation, the multimodal transport models that didn't consider carbon emissions and consider carbon emissions are analyzed. On this basis, a multi-objective programming 0-1 programming model with minimum total transportation cost and minimum total carbon emission is proposed. The idea of weight is applied to Ideal point method for solving problem, multi-objective programming is transformed into a single objective function. The optimal solution of carbon emission to transportation cost under different weights is determined by a single objective function with variable weights. Based on the model and algorithm, an example is given and the results are analyzed.

    Kemény, Ferenc; Meier, Beat

    2016-02-01

    While sequence learning research models complex phenomena, previous studies have mostly focused on unimodal sequences. The goal of the current experiment is to put implicit sequence learning into a multimodal context: to test whether it can operate across different modalities. We used the Task Sequence Learning paradigm to test whether sequence learning varies across modalities, and whether participants are able to learn multimodal sequences. Our results show that implicit sequence learning is very similar regardless of the source modality. However, the presence of correlated task and response sequences was required for learning to take place. The experiment provides new evidence for implicit sequence learning of abstract conceptual representations. In general, the results suggest that correlated sequences are necessary for implicit sequence learning to occur. Moreover, they show that elements from different modalities can be automatically integrated into one unitary multimodal sequence. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available To verify the influence of a priori information on the nonuniqueness problem of bioluminescence tomography (BLT, the multimodality imaging fusion based BLT experiment is performed by multiview noncontact detection mode, which incorporates the anatomical information obtained by the microCT scanner and the background optical properties based on diffuse reflectance measurements. In the reconstruction procedure, the utilization of adaptive finite element methods (FEMs and a priori permissible source region refines the reconstructed results and improves numerical robustness and efficiency. The comparison between the absence and employment of a priori information shows that multimodality imaging fusion is essential to quantitative BLT reconstruction.

    Full Text Available Background: The advanced era of technological development in child health care has resulted in more pediatric procedures being performed in various settings. Millions of children undergo surgery every year which is a stressful event. Many nonpharmacological strategies are being used to manage the preoperative fear and anxiety in children. The current study aims to assess the effectiveness of multimodal preoperative preparation program (MPPP on children undergoing surgery in terms of its effect on the psychophysiological parameters. Objective: The aim of this study is to assess the effectiveness of MPPP on the psychophysiological parameters of children undergoing surgery. Materials and Methods: A quasi-experimental study was conducted in a selected multi-specialty hospital. Using the purposive sampling technique, a total of 110 children aged 8–12 years were assigned to nonintervention (n = 55 and intervention (n = 55 groups, respectively. The MPPP was administered to the intervention group. The children in the nonintervention group received the routine preoperative care. Child's fear and anxiety was assessed on admission, prior to shifting the child to operation theater (OT, 24 and 48 h after surgery, whereas child's pulse, respiration, blood pressure (BP, and oxygen saturation was assessed on admission, prior to shifting the child to OT, 6, 12, 24, and 48 h after surgery and pain was assessed at 24 and 48 h after surgery. Results: The mean fear and anxiety scores of children were significantly lower in the intervention group than that of nonintervention group (P 0.05. This study also found that there is a significant association between the psychophysiological parameters of children with the selected demographic variables (P < 0.05.

    Major life changes are among factors that cause anxiety, and one of these changes is surgery. Emotional reactions to surgery have specific effects on the intensity and velocity as well as the process of physical disease. In addition, they can cause delay in patients recovery. This study is aimed at determining the relationship between religious beliefs and preoperative anxiety. This survey is a correlational study to assess the relationship between religious beliefs and preoperative anxiety of patients undergoing abdominal, orthopaedic, and gynaecologic surgery in educational hospitals. We used the convenience sampling method. The data collection instruments included a questionnaire containing the Spielberger State-Trait Anxiety Inventory (STAI), and another questionnaire formulated by the researcher with queries on religious beliefs and demographic characteristics as well as disease-related information. Analysis of the data was carried out with SPSS software using descriptive and inferential statistics. Results were arranged in three tables. The findings showed that almost all the subjects had high level of religiosity and moderate level of anxiety. In addition, there was an inverse relationship between religiosity and intensity of anxiety, though this was not statistically significant. The results of this study can be used as evidence for presenting religious counselling and spiritual interventions for individuals undergoing stress. Finally, based on the results of this study, the researcher suggested some recommendations for applying results and conducting further research.

    Full Text Available This article aimed at investigating the level of writing anxiety of the Iranian EFL students with different proficiency levels. To do so, 45 students (elementary, intermediate, and advanced learners studying in Azad University of Ilam, Iran were selected based on random sampling. Second, Language Writing Anxiety Inventory SLWAI (Cheng, 2004 was used to measure anxiety.  Both descriptive and inferential statistics including One-way ANOVA were run to analyze the data. Statistical analysis was conducted using Statistical Package for Social Science (SPSS. The results of the study indicated that the selected Iranian EFL students majoring in English language teaching experienced a high level of anxiety. In addition, students with elementary level were found to suffer higher level of English writing anxiety than the students with intermediate and advanced levels. Finally, based on the findings, cognitive anxiety was the most common type of anxiety, followed by somatic anxiety, and avoidance behavior. The results also highlighted the fact that foreign and second language teachers should be cautious of the dangers of  anxiety  and try  to  make  the  atmosphere  of  class  as  stress-free  as possible  in  order  to  improve  students’ performance.

  9. Multimodal integration of anatomy and physiology classes: How instructors utilize multimodal teaching in their classrooms

    Science.gov (United States)

    McGraw, Gerald M., Jr.

    Multimodality is the theory of communication as it applies to social and educational semiotics (making meaning through the use of multiple signs and symbols). The term multimodality describes a communication methodology that includes multiple textual, aural, and visual applications (modes) that are woven together to create what is referred to as an artifact. Multimodal teaching methodology attempts to create a deeper meaning to course content by activating the higher cognitive areas of the student's brain, creating a more sustained retention of the information (Murray, 2009). The introduction of multimodality educational methodologies as a means to more optimally engage students has been documented within educational literature. However, studies analyzing the distribution and penetration into basic sciences, more specifically anatomy and physiology, have not been forthcoming. This study used a quantitative survey design to determine the degree to which instructors integrated multimodality teaching practices into their course curricula. The instrument used for the study was designed by the researcher based on evidence found in the literature and sent to members of three associations/societies for anatomy and physiology instructors: the Human Anatomy and Physiology Society; the iTeach Anatomy & Physiology Collaborate; and the American Physiology Society. Respondents totaled 182 instructor members of two- and four-year, private and public higher learning colleges collected from the three organizations collectively with over 13,500 members in over 925 higher learning institutions nationwide. The study concluded that the expansion of multimodal methodologies into anatomy and physiology classrooms is at the beginning of the process and that there is ample opportunity for expansion. Instructors continue to use lecture as their primary means of interaction with students. Email is still the major form of out-of-class communication for full-time instructors. Instructors with

The data collection instruments included a questionnaire containing the Spielberger State-Trait Anxiety Inventory (STAI, and another questionnaire formulated by the researcher with queries on religious beliefs and demographic characteristics as well as disease-related information. Analysis of the data was carried out with SPSS software using descriptive and inferential statistics. Results were arranged in three tables. Results The findings showed that almost all the subjects had high level of religiosity and moderate level of anxiety. In addition, there was an inverse relationship between religiosity and intensity of anxiety, though this was not statistically significant. Conclusion The results of this study can be used as evidence for presenting religious counselling and spiritual interventions for individuals undergoing stress. Finally, based on the results of this study, the researcher suggested some recommendations for applying results and conducting further research.

    Real-world phenomena involve complex interactions between multiple signal modalities. As a consequence, humans are used to integrate at each instant perceptions from all their senses in order to enrich their understanding of the surrounding world. This paradigm can be also extremely useful in many signal processing and computer vision problems involving mutually related signals. The simultaneous processing of multimodal data can, in fact, reveal information that is otherwise hidden when considering the signals independently. However, in natural multimodal signals, the statistical dependencies between modalities are in general not obvious. Learning fundamental multimodal patterns could offer deep insight into the structure of such signals. In this paper, we present a novel model of multimodal signals based on their sparse decomposition over a dictionary of multimodal structures. An algorithm for iteratively learning multimodal generating functions that can be shifted at all positions in the signal is proposed, as well. The learning is defined in such a way that it can be accomplished by iteratively solving a generalized eigenvector problem, which makes the algorithm fast, flexible, and free of user-defined parameters. The proposed algorithm is applied to audiovisual sequences and it is able to discover underlying structures in the data. The detection of such audio-video patterns in audiovisual clips allows to effectively localize the sound source on the video in presence of substantial acoustic and visual distractors, outperforming state-of-the-art audiovisual localization algorithms.

    Social anxiety disorder (SAD) is characterized by fears of social and performance situations. Cognitive behavioral group therapy (CBGT) has in general positive effects on symptoms, distress and avoidance in SAD. Prior studies found increased cortical volumes and decreased fractional anisotropy (FA) in SAD compared with healthy controls (HCs). Thirty-three participants diagnosed with SAD attended in a 10-week CBGT and were scanned before and after therapy. We applied three neuroimaging methods-surface-based morphometry, diffusion tensor imaging and network-based statistics-each with specific longitudinal processing protocols, to investigate CBGT-induced structural brain alterations of the gray and white matter (WM). Surface-based morphometry revealed a significant cortical volume reduction (pre- to post-treatment) in the left inferior parietal cortex, as well as a positive partial correlation between treatment success (indexed by reductions in Liebowitz Social Anxiety Scale) and reductions in cortical volume in bilateral dorsomedial prefrontal cortex. Diffusion tensor imaging analysis revealed a significant increase in FA in bilateral uncinate fasciculus and right inferior longitudinal fasciculus. Network-based statistics revealed a significant increase of structural connectivity in a frontolimbic network. No partial correlations with treatment success have been found in WM analyses. For, we believe, the first time, we present a distinctive pattern of longitudinal structural brain changes after CBGT measured with three established magnetic resonance imaging analyzing techniques. Our findings are in line with previous cross-sectional, unimodal SAD studies and extent them by highlighting anatomical brain alterations that point toward the level of HCs in parallel with a reduction in SAD symptomatology.

  14. Reading Multimodal Texts for Learning – a Model for Cultivating Multimodal Literacy

    Full Text Available The re-conceptualisation of texts over the last 20 years, as well as the development of a multimodal understanding of communication and representation of knowledge, has profound consequences for the reading and understanding of multimodal texts, not least in educational contexts. However, if teachers and students are given tools to “unwrap” multimodal texts, they can develop a deeper understanding of texts, information structures, and the textual organisation of knowledge. This article presents a model for working with multimodal texts in education with the intention to highlight mutual multimodal text analysis in relation to the subject content. Examples are taken from a Singaporean science textbook as well as a Chilean science textbook, in order to demonstrate that the framework is versatile and applicable across different cultural contexts. The model takes into account the following aspects of texts: the general structure, how different semiotic resources operate, the ways in which different resources are combined (including coherence, the use of figurative language, and explicit/implicit values. Since learning operates on different dimensions – such as social and affective dimensions besides the cognitive ones – our inclusion of figurative language and values as components for textual analysis is a contribution to multimodal text analysis for learning.

    Objective: To analyze multimodal magnetic nanoparticles-Rhodamine B in culture media for cell labeling, and to establish a study of multimodal magnetic nanoparticles-Rhodamine B detection at labeled cells evaluating they viability at concentrations of 10 {mu}g Fe/mL and 100{mu}g Fe/mL. Methods: We performed the analysis of stability of multimodal magnetic nanoparticles-Rhodamine B in different culture media; the mesenchymal stem cells labeling with multimodal magnetic nanoparticles-Rhodamine B; the intracellular detection of multimodal magnetic nanoparticles-Rhodamine B in mesenchymal stem cells, and assessment of the viability of labeled cells by kinetic proliferation. Results: The stability analysis showed that multimodal magnetic nanoparticles-Rhodamine B had good stability in cultured Dulbecco's Modified Eagle's-Low Glucose medium and RPMI 1640 medium. The mesenchymal stem cell with multimodal magnetic nanoparticles-Rhodamine B described location of intracellular nanoparticles, which were shown as blue granules co-localized in fluorescent clusters, thus characterizing magnetic and fluorescent properties of multimodal magnetic nanoparticles Rhodamine B. Conclusion: The stability of multimodal magnetic nanoparticles-Rhodamine B found in cultured Dulbecco's Modified Eagle's-Low Glucose medium and RPMI 1640 medium assured intracellular mesenchymal stem cells labeling. This cell labeling did not affect viability of labeled mesenchymal stem cells since they continued to proliferate for five days. (author)

    Communication is essential for successful rehabilitation, yet few aphasia treatments have been investigated during the acute stroke phase. Alternative modality use including gesturing, writing, or drawing has been shown to increase communicative effectiveness in people with chronic aphasia. Instruction in alternative modality use during acute stroke may increase patient communication and participation, therefore resulting in fewer adverse situations and improved rehabilitation outcomes. The study purpose was to explore a multimodal communication program for aphasia (MCPA) implemented during acute stroke rehabilitation. MCPA aims to improve communication modality production, and to facilitate switching among modalities to resolve communication breakdowns. Two adults with severe aphasia completed MCPA beginning at 2 and 3 weeks post onset a single left-hemisphere stroke. Probes completed during each session allowed for evaluation of modality production and modality switching accuracy. Participants completed MCPA (10 and 14 treatment sessions respectively) and their performance on probes suggested increased accuracy in the production of various alternate communication modalities. However, increased switching to an alternate modality was noted for only one participant. Further investigation of multimodal treatment during inpatient rehabilitation is warranted. In particular, comparisons between multimodal and standard treatments would help determine appropriate interventions for this setting.

  20. Multimodal label-free microscopy

    Directory of Open Access Journals (Sweden)

    Nicolas Pavillon

    2014-09-01

    Full Text Available This paper reviews the different multimodal applications based on a large extent of label-free imaging modalities, ranging from linear to nonlinear optics, while also including spectroscopic measurements. We put specific emphasis on multimodal measurements going across the usual boundaries between imaging modalities, whereas most multimodal platforms combine techniques based on similar light interactions or similar hardware implementations. In this review, we limit the scope to focus on applications for biology such as live cells or tissues, since by their nature of being alive or fragile, we are often not free to take liberties with the image acquisition times and are forced to gather the maximum amount of information possible at one time. For such samples, imaging by a given label-free method usually presents a challenge in obtaining sufficient optical signal or is limited in terms of the types of observable targets. Multimodal imaging is then particularly attractive for these samples in order to maximize the amount of measured information. While multimodal imaging is always useful in the sense of acquiring additional information from additional modes, at times it is possible to attain information that could not be discovered using any single mode alone, which is the essence of the progress that is possible using a multimodal approach.

    Along with physical and biological changes, a tremendous amount of upheaval and adjustment accompany the pregnancy and postpartum period of a woman's life that together can often result in what is commonly known as postpartum depression. However, anxiety disorders have been found to be more frequent than depression during pregnancy and at least as common, if not more so, during the postpartum period, e.g., Brockington et al., (Archieves Women's Ment Health 9:253-263, 2006; Wenzel et al. (J Anxiety Disord, 19:295-311, 2005). Cognitive-behavioral therapy (CBT) is a well-established psychological treatment of choice for anxiety; however, few studies have specifically examined a cognitive-behavioral intervention targeting perinatal anxiety. This pilot study examined the effectiveness of a cognitive-behavioral group treatment (CBGT) program specifically tailored to address perinatal anxiety in 10 women who were either pregnant or within 12 months postpartum. Participants were recruited from a women's clinic at an academic hospital setting, with anxiety identified as their principal focus of distress. Following a diagnostic interview confirming a primary anxiety disorder and completion of assessment measures, participants completed a 6-week CBGT program. There was a statistically significant reduction in anxiety and depressive symptoms following the CBGT program (all p anxiety. These findings suggest that CBGT for perinatal anxiety is a promising treatment for both anxiety and depressive symptoms experienced during the perinatal period. Further studies are needed to evaluate the treatment efficacy through larger controlled trials.

    Whether course trajectories of depressive and anxiety disorders are different, remains an important question for clinical practice and informs future psychiatric nosology. This longitudinal study compares depressive and anxiety disorders in terms of diagnostic and symptom course trajectories, and examines clinical prognostic factors. Data are from 1209 depressive and/or anxiety patients residing in primary and specialized care settings, participating in the Netherlands Study of Depression and Anxiety. Diagnostic and Life Chart Interviews provided 2-year course information. Course was more favorable for pure depression (n=267, median episode duration = 6 months, 24.5% chronic) than for pure anxiety (n=487, median duration = 16 months, 41.9% chronic). Worst course was observed in the comorbid depression-anxiety group (n=455, median duration > 24 months, 56.8% chronic). Independent predictors of poor diagnostic and symptom trajectory outcomes were severity and duration of index episode, comorbid depression-anxiety, earlier onset age and older age. With only these factors a reasonable discriminative ability (C-statistic 0.72-0.77) was reached in predicting 2-year prognosis. Depression and anxiety cases concern prevalent - not incident - cases. This, however, reflects the actual patient population in primary and specialized care settings. Their differential course trajectory justifies separate consideration of pure depression, pure anxiety and comorbid anxiety-depression in clinical practice and psychiatric nosology.

    Full Text Available The attention deficit hyperactivity disorder (ADHD, one of the most commonly diagnosed psychiatric disorders among school aged children, continues to create disputes between specialists, upon the best treatment to be used. The herby study aims to bring forward some differences that may exist between the efficacy of the multimodal treatment compared to the drug treatment of ADHD. The novelty component of this study, unfolded February 2010-July 2012, is that the children, their parents and also their teachers were included in the multimodality treatment. The children included in this research (n=63, aged 6-14 and ADHD diagnosed, were randomly assigned in two groups. In the medication (Med group (n=32 the children only received the specific pharmacological treatment (Atomoxetine or Methylphenidate, and for the multimodality (MM group (n=31 the therapy included psychosocial interventions besides the drug therapy. All children were evaluated, both pre and post intervention, with the Achenbach System of Empirically Based Assessment – ASEBA, for the 6-18 aged category. We have compared the influence of therapy on the core symptoms, on the adaptive functionality and academic performance and on the competences and social functioning of the children in the two groups. The multimodal intervention proved to be more effective (p<0.05 than medication alone, firstly in ameliorating the child’s social behavior in both family and school environment, than in what concerns the main ADHD symptoms. The children’s academic performance was little impacted by either of the two therapies.

    Full Text Available The default mode network (DMN is one of the most widely studied resting state functional networks. The structural basis for the DMN is of particular interest and has been studied by several researchers using diffusion tensor imaging (DTI. Most of these previous studies focused on a few regions or white matter tracts of the DMN so that the global structural connectivity pattern and network properties of the DMN remain unclear. Moreover, evidences indicate that the DMN is involved in both memory and emotion, but how the DMN regulates memory and anxiety from the perspective of the whole DMN structural network remains unknown. We used multimodal neuroimaging methods to investigate the structural connectivity pattern of the DMN and the association of its network properties with memory and anxiety in 205 young healthy subjects. Using a probabilistic fiber tractography technique based on DTI data and graph theory methods, we constructed the global structural connectivity pattern of the DMN and found that memory quotient (MQ score was significantly positively correlated with the global and local efficiency of the DMN whereas anxiety was found to be negatively correlated with the efficiency. The strong structural connectivity between multiple brain regions within DMN may reflect that the DMN has certain structural basis. Meanwhile, we found the network efficiency of the DMN were related to memory and anxiety measures, which indicated that the DMN may play a role in the memory and anxiety.

    The Nuclear Anxiety Scale was administered to 263 undergraduate and graduate studies (on eight occasions in December, 1985 and January, 1986). (1) The obtained alpha coefficient was .91. This was significant at the .01 level, and demonstrated that the scale was internally homogeneous and consistent. (2) Item discrimination indices (point biserial correlation coefficients) computered for the thirty (30) items yielded a range of .25 to .64. All coefficients were significant at the .01 level, and all 30 items were retained as demonstrating significant discriminability. (3) The correlation between two administrations of the scale (with a 48-hour interval) was .83. This was significant at the .01 level, and demonstrated test-retest reliability and stability over time. (4) The point-biserial correlation coefficient between scores on the Nuclear Anxiety Scale, and the students' self-report of nuclear anxiety as being either a high or low ranked stressor, was .59. This was significant at the .01 level, and demonstrated concurrent validity. (5) The correlation coefficient between scores on the Nuclear Anxiety Scale and the Spielberger State-Trait Anxiety Inventory, A-Trait, (1970), was .41. This was significant at the .01 level, and demonstrated convergent validity. (6) The correlation coefficient between positively stated and negatively stated items (with scoring reversed) was .76. This was significant at the .01 level, and demonstrated freedom from response set bias

    The objective of this study was to explore how maternal mood during pregnancy, i.e., general anxiety, pregnancy-specific anxiety, and depression predicted parenting stress 3 months after giving birth, thereby shaping the child's early postnatal environmental circumstances. To this end, data were used from 1073 women participating in the Dutch longitudinal cohort Generations 2 , which studies first-time pregnant mothers during pregnancy and across the transition to parenthood. Women filled out the State Trait Anxiety Inventory (STAI), Pregnancy-Related Anxiety Questionnaire-revised (PRAQ-R), and Beck Depression Index (BDI) three times during pregnancy: at 12, 22, and 32 weeks gestational age. Three months postpartum, a parenting stress questionnaire was filled out yielding seven different parenting constructs. Latent scores were computed for each of the repeatedly measured maternal mood variables with Mplus and parenting stress constructs were simultaneously regressed on these latent scores. Results showed that trait anxiety and pregnancy-specific anxiety were uniquely related to almost all parenting stress constructs, taking depression into account. Early prevention and intervention to reduce maternal anxiety in pregnancy could hold the key for a more advantageous trajectory of early postnatal parenting.

    Mercer, Gary J.

    This quantitative study examined the relationship between secondary students with math anxiety and physics performance in an inquiry-based constructivist classroom. The Revised Math Anxiety Rating Scale was used to evaluate math anxiety levels. The results were then compared to the performance on a physics standardized final examination. A simple correlation was performed, followed by a multivariate regression analysis to examine effects based on gender and prior math background. The correlation showed statistical significance between math anxiety and physics performance. The regression analysis showed statistical significance for math anxiety, physics performance, and prior math background, but did not show statistical significance for math anxiety, physics performance, and gender.

    Cognitive behavioral therapy (CBT) for anxiety disorders is effective, but nonadherence with treatment may reduce the benefits of CBT. This study examined (a) four baseline domains (i.e., demographic, youth clinical characteristics, therapy related, family/parent factors) as predictors of youth adherence with treatment and (b) the associations between youth adherence and treatment outcomes. Data were from 279 youth (7-17 years of age, 51.6% female; 79.6% White, 9% African American), with Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.) diagnoses of separation anxiety disorder, generalized anxiety disorder, and/or social phobia, who participated in CBT in the Child/Adolescent Anxiety Multimodal Study. Adherence was defined in three ways (session attendance, therapist-rated compliance, and homework completion). Multiple regressions revealed several significant predictors of youth adherence with CBT, but predictors varied according to the definition of adherence. The most robust predictors of greater adherence were living with both parents and fewer youth comorbid externalizing disorders. With respect to outcomes, therapist ratings of higher youth compliance with CBT predicted several indices of favorable outcome: lower anxiety severity, higher global functioning, and treatment responder status after 12 weeks of CBT. Number of sessions attended and homework completion did not predict treatment outcomes. Findings provide information about risks for youth nonadherence, which can inform treatment and highlight the importance of youth compliance with participating in therapy activities, rather than just attending sessions or completing homework assignments.

    Full Text Available Multimodal molecular imaging can offer a synergistic improvement of diagnostic ability over a single imaging modality. Recent development of hybrid imaging systems has profoundly impacted the pool of available multimodal imaging probes. In particular, much interest has been focused on biocompatible, inorganic nanoparticle-based multimodal probes. Inorganic nanoparticles offer exceptional advantages to the field of multimodal imaging owing to their unique characteristics, such as nanometer dimensions, tunable imaging properties, and multifunctionality. Nanoparticles mainly based on iron oxide, quantum dots, gold, and silica have been applied to various imaging modalities to characterize and image specific biologic processes on a molecular level. A combination of nanoparticles and other materials such as biomolecules, polymers, and radiometals continue to increase functionality for in vivo multimodal imaging and therapeutic agents. In this review, we discuss the unique concepts, characteristics, and applications of the various multimodal imaging probes based on inorganic nanoparticles.

    Cancer cachexia is common and reduces function, treatment tolerability and quality of life. Given its multifaceted pathophysiology a multimodal approach to cachexia management is advocated for, but can be difficult to realise in practice. We use a case-based approach to highlight practical approaches to the multimodal management of cachexia for patients across the cancer trajectory. Four cases with lung cancer spanning surgical resection, radical chemoradiotherapy, palliative chemotherapy and no anticancer treatment are presented. We propose multimodal care approaches that incorporate nutritional support, exercise, and anti-inflammatory agents, on a background of personalized oncology care and family-centred education. Collectively, the cases reveal that multimodal care is part of everyone's remit, often focuses on supported self-management, and demands buy-in from the patient and their family. Once operationalized, multimodal care approaches can be tested pragmatically, including alongside emerging pharmacological cachexia treatments. We demonstrate that multimodal care for cancer cachexia can be achieved using simple treatments and without a dedicated team of specialists. The sharing of advice between health professionals can help build collective confidence and expertise, moving towards a position in which every team member feels they can contribute towards multimodal care.

    Type 2 diabetes mellitus (T2DM) is a risk factor for dementia. Mild cognitive impairment (MCI), an intermediary state between normal cognition and dementia, often occurs during the prodromal diabetic stage, making early diagnosis and intervention of MCI very important. Latest neuroimaging techniques revealed some underlying microstructure alterations for diabetic MCI, from certain aspects. But there still lacks an integrated multimodal MRI system to detect early neuroimaging changes in diabetic MCI patients. Thus, we intended to conduct a diagnostic trial using multimodal MRI techniques to detect early diabetic MCI that is determined by the Montreal Cognitive Assessment (MoCA). In this study, healthy controls, prodromal diabetes and diabetes subjects (53 subjects/group) aged 40-60 years will be recruited from the physical examination center of Tangdu Hospital. The neuroimaging and psychometric measurements will be repeated at a 0.5 year-interval for 2.5 years’ follow-up. The primary outcome measures are 1) Microstructural and functional alterations revealed with multimodal MRI scans including structure magnetic resonance imaging (sMRI), resting state functional magnetic resonance imaging (rs-fMRI), diffusion kurtosis imaging (DKI), and three-dimensional pseudo-continuous arterial spin labeling (3D-pCASL); 2) Cognition evaluation with MoCA. The second outcome measures are obesity, metabolic characteristics, lifestyle and quality of life. The study will provide evidence for the potential use of multimodal MRI techniques with psychometric evaluation in diagnosing MCI at prodromal diabetic stage so as to help decision making in early intervention and improve the prognosis of T2DM.

    Previous studies examining the relationship of anxiety scores, derived from the content analysis of speech of normal individuals, have revealed that the anxiety scores occurring in the dreams associated with rapid eye movement (REM) sleep are significantly correlated with localized cerebral glucose metabolic rates assessed by positron emission tomography (PET) scanning. These significant intercorrelations occur in different cerebral areas when the anxiety scores are obtained from mental experiences reported during non-REM sleep or during wakeful silent mentation. The purpose of the present study was to examine the intercorrelations found between anxiety attributed to the self, anxiety-displacement, and anxiety denial measured from computerized content analysis of 5-min verbal reports of subjective thoughts and feelings obtained from wakeful normal subjects and localized cerebral glucose metabolic rates during PET scanning. The subjects were 10 wakeful young males. Their anxiety scores were derived from computerized content analysis of 5-min reports they gave of their subjective thoughts, feelings and fantasies during a 30-min period following an intravenous injection of F D-deoxyglucose (FDG). The subjects were moved 32--45 min after this injection to obtain a PET scan, which records all of the localized cerebral glucose metabolic rates during the 30 min following the FDG injection. Significant intercorrelations of localized cerebral glucose metabolic rates with the scores of self-anxiety, anxiety displacement, and anxiety-denial were found in dissimilar cerebral locations depending on the type of anxiety involved. The significant correlations occurred in brain regions known to be associated with the functions of emotions, cognition, memory, and vision. Specific combinations of cerebral areas, based on glucose metabolic rates, appear to distinguish and be associated with different verbal expressions of anxiety. Replication of this preliminary research will be

    The high costs of development and maintenance of multimodal grammars in integrating and understanding input in multimodal interfaces lead to the investigation of novel algorithmic solutions in automating grammar generation and in updating processes. Many algorithms for context-free grammar inference have been developed in the natural language processing literature. An extension of these algorithms toward the inference of multimodal grammars is necessary for multimodal input processing. In this paper, we propose a novel grammar inference mechanism that allows us to learn a multimodal grammar from its positive samples of multimodal sentences. The algorithm first generates the multimodal grammar that is able to parse the positive samples of sentences and, afterward, makes use of two learning operators and the minimum description length metrics in improving the grammar description and in avoiding the over-generalization problem. The experimental results highlight the acceptable performances of the algorithm proposed in this paper since it has a very high probability of parsing valid sentences.

    Cigarette smoking is increased in people with trait anxiety and anxiety disorders, however no longitudinal data exist illuminating whether smoking in adolescence can influence the developmental trajectory of anxiety symptoms from early vulnerability in infancy to adult anxiety expression. Using The Tracing Opportunities and Problems in Childhood and Adolescence (TOPP) Study, a community-based cohort of children and adolescents from Norway who were observed from the age of 18months to age 18–19years, we explored the relationship between adolescent smoking, early vulnerability for anxiety in infancy (e.g. shyness, internalizing behaviors, emotional temperaments) and reported early adult anxiety. Structural equation modeling demonstrated that adolescent active smoking was positively associated with increased early adulthood anxiety (β = 0.17, panxiety did not predict early adult smoking. Adolescent active smoking was a significant effect modifier in the relationship between some infant vulnerability factors and later anxiety; smoking during adolescence moderated the relationship between infant internalizing behaviors (total sample: active smokers: β = 0.85,panxiety in early adulthood. The results support a model where smoking acts as an exogenous risk factor in the development of anxiety, and smoking may alter the developmental trajectory of anxiety from infant vulnerability to early adult anxiety symptom expression. Although alternative non-mutually exclusive models may explain these findings, the results suggest that adolescent smoking may be a risk factor for adult anxiety, potentially by influencing anxiety developmental trajectories. Given the known adverse health effects of cigarette smoking and significant health burden imposed by anxiety disorders, this study supports the importance of smoking prevention and cessation programs targeting children and adolescence.

    We combine extant theories of evidence accumulation and multi-modal integration to develop an integrated framework for modeling multimodal integration as a process that unfolds in real time. Many studies have formulated sensory processing as a dynamic process where noisy samples of evidence are accumulated until a decision is made. However, these studies are often limited to a single sensory modality. Studies of multimodal stimulus integration have focused on how best to combine different sources of information to elicit a judgment. These studies are often limited to a single time point, typically after the integration process has occurred. We address these limitations by combining the two approaches. Experimentally, we present data that allow us to study the time course of evidence accumulation within each of the visual and auditory domains as well as in a bimodal condition. Theoretically, we develop a new Averaging Diffusion Model in which the decision variable is the mean rather than the sum of evidence samples and use it as a base for comparing three alternative models of multimodal integration, allowing us to assess the optimality of this integration. The outcome reveals rich individual differences in multimodal integration: while some subjects' data are consistent with adaptive optimal integration, reweighting sources of evidence as their relative reliability changes during evidence integration, others exhibit patterns inconsistent with optimality.

    In light of increased emphasis on evidence-based practice in the profession of dental hygiene, it is important that today's dental hygienist comprehend statistical measures to fully understand research articles, and thereby apply scientific evidence to practice. Therefore, the purpose of this study was to investigate statistics anxiety among graduate dental hygiene students in the U.S. A web-based self-report, anonymous survey was emailed to directors of 17 MSDH programs in the U.S. with a request to distribute to graduate students. The survey collected data on statistics anxiety, sociodemographic characteristics and evidence-based practice. Statistic anxiety was assessed using the Statistical Anxiety Rating Scale. Study significance level was α=0.05. Only 8 of the 17 invited programs participated in the study. Statistical Anxiety Rating Scale data revealed graduate dental hygiene students experience low to moderate levels of statistics anxiety. Specifically, the level of anxiety on the Interpretation Anxiety factor indicated this population could struggle with making sense of scientific research. A decisive majority (92%) of students indicated statistics is essential for evidence-based practice and should be a required course for all dental hygienists. This study served to identify statistics anxiety in a previously unexplored population. The findings should be useful in both theory building and in practical applications. Furthermore, the results can be used to direct future research. Copyright © 2015 The American Dental Hygienists’ Association.

    Recently, Augmented Reality (AR) is an emerging technology in many mobile applications. Mobile AR was defined as a medium for displaying information merged with the real world environment mapped with augmented reality surrounding in a single view. There are four main types of mobile augmented reality interfaces and one of them are multimodal interfaces. Multimodal interface processes two or more combined user input modes (such as speech, pen, touch, manual gesture, gaze, and head and body movements) in a coordinated manner with multimedia system output. In multimodal interface, many frameworks have been proposed to guide the designer to develop a multimodal applications including in augmented reality environment but there has been little work reviewing the framework of adaptive multimodal interface in mobile augmented reality. The main goal of this study is to propose a conceptual framework to illustrate the adaptive multimodal interface in mobile augmented reality. We reviewed several frameworks that have been proposed in the field of multimodal interfaces, adaptive interface and augmented reality. We analyzed the components in the previous frameworks and measure which can be applied in mobile devices. Our framework can be used as a guide for designers and developer to develop a mobile AR application with an adaptive multimodal interfaces.

    Non-pharmacological approaches to pain management have been used by therapists for decades to reduce the anxiety and pain experienced by children during burn care procedures. With a greater understanding of pain and the principles behind what causes a child to be distracted, combined with access to state of the art technology, we have developed an easy to use, hand held multimodal distraction device (MMD). MMD is an interactive device that prepares the child for a procedure and uses developmentally appropriate distraction stories and games during the procedures to alleviate anxiety and pain. This paper summarizes the results of three randomized control trials. The trials aimed to understand the effectiveness of MMD as a distraction and preparation tool in reducing anxiety and pain in children undergoing burns and non-burns medical procedures compared to pure pharmacological approaches Standard Distraction (SD) and off the shelf video games (VG). Three separate prospective randomized control trials involving 182 children having 354 dressing changes were conducted in the burns and orthopedic departments at Royal Children's Hospital, Brisbane, Australia, to address the above aims. Pain and anxiety scores were completed for the child, caregiver and nursing staff according to the Modified Faces, Legs, Activity, Cry and Consolability Scale, Faces Pain Scale-Revised, Visual Analogue Scale and Wong-Baker Faces Pain Rating Scale. Procedural length was recorded. MMD as a preparation and distraction tool were shown to have a significant impact on child, parent and nursing staff reported anxiety and pain during procedures compared to standard care and video games (P positive effect on clinical time and was shown to sustain its impact on pain and time with further dressing changes. MMD is more effective in reducing the pain and anxiety experienced by children in acute medical procedures as compared with SD and VG. MMD is continuing to be trialed and is continuing to show

    Full Text Available Studies on potentials of feedback over English language teaching seem not to have not been well-revealed, including studies on the use of feedback to improve English pre-service teachers’ competence. The present study investigates to what extent a multimodal feedback can influence pre-service teachers’ teaching, and which teaching aspects are influenced. Twenty five pre-service teachers taking Microteaching Course served as respondents supervised by a course advisor. The data were collected by teacher observation in a rating-scale form, self-appraisal, and interviews. The data were analyzed by using correlated sample t-test and the eight teaching components proposed by Brown (2001. The results showed that after multimodal feedback provision, pre-service teachers indicated an improvement significantly in seven out of eight teaching aspects. The provision of multimodal feedback could improve their teaching competence on preparation, instructional objective elicitation, mastery of instructional materials, use of media, and classroom management, including classroom language. But, the results do not indicate that they perform well on reflection and follow-up due to some reasons. In addition, the results evince that multimodal feedback provision could improve pre-service teachers’ pedagogical competence when the multimodal feedback is integrated with content, interpersonal relationship, and management.

Methods This is a cross-sectional study, initially composed of 2,457 adolescents, aged between 10-17 years old, from public schools of the area covered by the Basic Health Unit of a university hospital. We applied the Screen for Child Anxiety Related Emotional Disorders (SCARED to assess for anxiety disorders. Then, 138 positive cases in the screening were assessed for mental disorders through the Schedule for Affective Disorder and Schizophrenia for School-Age Children – Present and Lifetime Version (K-SADS-PL. Results Patients with anxiety disorders had more association with other anxiety disorders, as well as depression, and enuresis. The most common comorbidity described in our study was between generalized anxiety disorder and separation anxiety disorder (OR = 4.21, 95% CI 1.88, 9.58. Significant association was observed between other disorders such as enuresis and separation anxiety disorder (OR = 3.81, 95% CI 1.16, 12.49, as well as depression and generalized anxiety disorder (OR = 3.40; 95% CI 1.52, 7.61. Conclusion Our study showed a relevant presence of comorbidities adolescents with anxiety disorders, selected from a community sample, especially regarding other anxiety disorders. Nevertheless, further studies are needed to confirm our findings.

    There is an explicit and implicit assumption in multimodal traffic equilibrium models, that is, if the equilibrium exists, then it will also occur. The assumption is very idealized; in fact, it may be shown that the quite contrary could happen, because in multimodal traffic network, especially in mixed traffic conditions the interaction among traffic modes is asymmetric and the asymmetric interaction may result in the instability of traffic system. In this paper, to study the stability of multimodal traffic system, we respectively present the travel cost function in mixed traffic conditions and in traffic network with dedicated bus lanes. Based on a day-to-day dynamical model, we study the evolution of daily route choice of travelers in multimodal traffic network using 10000 random initial values for different cases. From the results of simulation, it can be concluded that the asymmetric interaction between the cars and buses in mixed traffic conditions can lead the traffic system to instability when traffic demand is larger. We also study the effect of travelers' perception error on the stability of multimodal traffic network. Although the larger perception error can alleviate the effect of interaction between cars and buses and improve the stability of traffic system in mixed traffic conditions, the traffic system also become instable when the traffic demand is larger than a number. For all cases simulated in this study, with the same parameters, traffic system with dedicated bus lane has better stability for traffic demand than that in mixed traffic conditions. We also find that the network with dedicated bus lane has higher portion of travelers by bus than it of mixed traffic network. So it can be concluded that building dedicated bus lane can improve the stability of traffic system and attract more travelers to choose bus reducing the traffic congestion. (general)

    Background Little is known about seasonality of specific depressive symptoms and anxiety symptoms in different patient populations. This study aims to assess seasonal variation of depressive and anxiety symptoms in a primary care population and across participants who were classified in diagnostic groups 1) healthy controls 2) patients with a major depressive disorder, 3) patients with any anxiety disorder and 4) patients with a major depression and any anxiety disorder. Methods Data were used from the Netherlands Study of Depression and Anxiety (NESDA). First, in 5549 patients from the NESDA primary care recruitment population the Kessler-10 screening questionnaire was used and data were analyzed across season in a multilevel linear model. Second, in 1090 subjects classified into four groups according to psychiatric status according to the Composite International Diagnostic Interview, overall depressive symptoms and atypical versus melancholic features were assessed with the Inventory of Depressive Symptoms. Anxiety and fear were assessed with the Beck Anxiety Inventory and the Fear questionnaire. Symptom levels across season were analyzed in a linear regression model. Results In the primary care population the severity of depressive and anxiety symptoms did not show a seasonal pattern. In the diagnostic groups healthy controls and patients with any anxiety disorder, but not patients with a major depressive disorder, showed a small rise in depressive symptoms in winter. Atypical and melancholic symptoms were both elevated in winter. No seasonal pattern for anxiety symptoms was found. There was a small gender related seasonal effect for fear symptoms. Conclusions Seasonal differences in severity or type of depressive and anxiety symptoms, as measured with a general screening instrument and symptom questionnaires, were absent or small in effect size in a primary care population and in patient populations with a major depressive disorder and anxiety disorders.

    Background This study aimed to evaluate the psychometric properties of the Korean version of the Clinically Useful Anxiety Outcome Scale (CUXOS) and to examine the current diagnostic comorbidity and differential severity of anxiety symptoms between major depressive disorder (MDD) and anxiety disorders. Methodology In total, 838 psychiatric outpatients were analyzed at their intake appointment. Diagnostic characteristics were examined using the structured clinical interview from the DSM-IV because the DSM5 was not available at the start of the study. The CUXOS score was measured and compared with that of 3 clinician rating scales and 4 self-report scales. Principal findings The CUXOS showed excellent results for internal consistency (Cronbach’s α = 0.90), test–retest reliability (r = 0.74), and discriminant and convergent validity. The CUXOS significantly discriminated between different levels of anxiety severity, and the measure was sensitive to change after treatment. Approximately 45% of patients with MDD were additionally diagnosed with anxiety disorders while 55% of patients with anxiety disorders additionally reported an MDD. There was a significant difference in CUXOS scores between diagnostic categories (MDD only, anxiety only, both disorders, and no MDD or anxiety disorder). The CUXOS scores differed significantly between all categories of depression (major, minor, and non-depression) except for the comparison between minor depression and non-depression groups. Conclusions The Korean version of the CUXOS is a reliable and valid measure of the severity of anxiety symptoms. The use of the CUXOS could broaden the understanding of coexisting and differentiating characteristics of anxiety and depression. PMID:28604808

    2016-04-01

    Life events, recognized as stressors, due to their unanticipated nature, can cause psychiatric illness. Also there is some line of continuity between neurotic illness and antecedent personality traits. To study generalized anxiety disorder in relation to Life events and personality dimensions. Certain hypotheses were tested in two groups, namely 30 Generalized Anxiety Disorder patients (GAD) and 30 matched controls, by utilizing assessment tools. These include: GAD patients experience more undesirable Life events than normal; GAD patients with high level of anxiety experience more undesirable Life events; Neuroticism is related to the severity of anxiety; Extroverts experience more anxiety; Level of anxiety in females is higher; GAD patients with higher education level experience more anxiety, while those with lower education level somatize more. The group differences were examined using Chi-Square test, Student t-test and ANOVA. Pearson's Correlation Co-efficient was used to find the correlation between anxiety and the undesirable Life events. The level of statistical significance was set at panxiety experienced more undesirable Life events, with the coefficient of correlation being quite high. A significant association between Neuroticism scale and GAD was observed. The study suggests a possible causative link between the undesirable Life events and GAD; and a significant association between Neuroticism dimension and the anxiety disorder. Role of environmental stressors and personality traits in treatment outcome among GAD patients awaits further, prospective studies.

    There is evidence for an association between social anxiety and emotion regulation difficulties. This study investigates that emotion regulation difficulties are specific to two domains of social anxiety. An explorative study was conducted to examine the associations between emotion regulation facets and social anxiety in the normal population. N= 149 healthy volunteers participated in an internet-based survey. Emotion regulation deficits were measured by the Difficulties in Emotion Regulation Scale which consists of six subscales. Social anxiety was measured by the Social Phobia Scale and the Social Interaction Anxiety Scale. Hierarchical regression analyses showed that anxiety of interactive social situations is associated with non-acceptance of negative emotions, impulse control difficulties, and lack of functional emotion regulation strategies over and above the impact of age and general psychopathology. In contrast, anxiety of being observed by others was not specifically associated with emotion regulation strategies. The results support the hypothesis that specific emotion regulation deficits are relevant to specific aspects of social anxiety. Implications for further research and therapy are discussed. © 2011 The British Psychological Society.

    Full Text Available Objective: To assess the prevalence of anxiety disorders and associated factors in young adults. Methods: Cross-sectional population-based study of individuals between the ages of 18 and 24 years randomly selected from 89 census-based sectors to ensure an adequate sample size. Household selection within the sectors was performed according to a systematic sampling process. Anxiety disorders were assessed using the Mini International Neuropsychiatric Interview (MINI. The final sample comprised 1,560 young adults. Results: Of the participants who were diagnosed with anxiety disorders, 12.3% had agoraphobia, 9.7% had generalised anxiety disorder, 4.0% had social phobia, 3.3% had obsessive-compulsive disorder, 2.5% had panic disorder, and 2.1% had post-traumatic stress disorder; only 23.8% had received any previous treatment. Anxiety disorders were associated with sex, socioeconomic status, psychiatric problems in parents, alcohol abuse, and tobacco use. Conclusions: The identification of factors associated with anxiety disorders in young people enables us to develop intervention strategies. Anxiety disorders are not only highly prevalent but are also associated with significant functional impairment, significant reductions in quality of life, lower productivity, and higher rates of comorbidities.

    Multitasking information behavior involves multiple forms of information searching such as library and Web search. Few researchers, however, have explored multitasking information behavior and information task switching in libraries in conjunction with psychological variables. This study explored this behavior in terms of anxiety under time pressure. This was an exploratory case study. Participant searched information for three unrelated everyday life information topics during a library visit, in a timeframe of one hour. The data collection tools used were: diary, observation, interview, and the State-Trait Anxiety Inventory test. Participant took the Trait-anxiety test before the library visit to measure anxiety level as a personal characteristic. She also took State-anxiety test before, during and after the library visit to measure anxiety levels regarding the information seeking behavior. The results suggested that participant had high levels of anxiety at the beginning of the multitasking information behavior. The reason for that was the concern about the performance as well as the identification of the right resources. During the multitasking information behavior, participant still had anxiety to find the right information. The levels of anxiety, however, were less due to library’s good organized structure. At the end of the information seeking process, the levels of anxiety dropped significant and therefore calm and safety returned. Finally, participant searched information for topics that were more important and for which she had prior knowledge When people, under time pressure, have access to well organized information, the levels of anxiety might decrease

    Guckes, Amber

    This study consists of both computational and experimental investigations. The computational results enabled detector design selections and confirmed experimental results. The experimental results determined that the CLYC scintillation detector can be applied as a functional and field-deployable multimode radiation sensor. The computational study utilized MCNP6 code to investigate the response of CLYC to various incident radiations and to determine the feasibility of its application as a handheld multimode sensor and as a single-scintillator collimated directional detection system. These simulations include: • Characterization of the response of the CLYC scintillator to gamma-rays and neutrons; • Study of the isotopic enrichment of 7Li versus 6Li in the CLYC for optimal detection of both thermal neutrons and fast neutrons; • Analysis of collimator designs to determine the optimal collimator for the single CLYC sensor directional detection system to assay gamma rays and neutrons; Simulations of a handheld CLYC multimode sensor and a single CLYC scintillator collimated directional detection system with the optimized collimator to determine the feasibility of detecting nuclear materials that could be encountered during field operations. These nuclear materials include depleted uranium, natural uranium, low-enriched uranium, highly-enriched uranium, reactor-grade plutonium, and weapons-grade plutonium. The experimental study includes the design, construction, and testing of both a handheld CLYC multimode sensor and a single CLYC scintillator collimated directional detection system. Both were designed in the Inventor CAD software and based on results of the computational study to optimize its performance. The handheld CLYC multimode sensor is modular, scalable, low?power, and optimized for high count rates. Commercial?off?the?shelf components were used where possible in order to optimize size, increase robustness, and minimize cost. The handheld CLYC multimode

    As clinical practice and experimental studies show, symptoms of depression and anxiety often accompany each other. It is well known that combination of anxiety and depression in patients is treated more slowly, requires large doses of drugs, increases the likelihood of suicide and often leads to relapse. Furthermore, antidepressants and anxiolytics exert its therapeutic effect in limited cases even in monopolar anxiety or depression state. In this review of literature and our own data the relationship of anxiety and depression is analyzed. It has been shown with using the model of mixed anxiety/depression disorder caused by chronic social defeat stress, that the anxiety and depression are changed under the influence of psychotropic drugs independently.

    2016-01-01

    This study examined (a) whether, in line with a gene-environment correlation (rGE), a genetic disposition for anxiety puts children at risk of having anxious friends or having no reciprocal friends; (b) to what extent these friendship experiences are related to anxiety symptoms, when controlling for sex and genetic disposition for this trait; and (c) the additive and interactive predictive links of the reciprocal best friend's anxiety symptoms and of friendship quality with children's anxiety symptoms. Using a genetically informed design based on 521 monozygotic and ic twins (264 girls; 87% of European descent) assessed in Grade 4 (M age = 10.04 years, SD = .26), anxiety symptoms and perceived friendship quality were measured with self-report questionnaires. Results indicated that, in line with rGE, children with a strong genetic disposition for anxiety were more likely to have anxious friends than nonanxious friends. Moreover, controlling for their genetic risk for anxiety, children with anxious friends showed higher levels of anxiety symptoms than children with nonanxious friends but did not differ from those without reciprocal friends. Additional analyses suggested a possible contagion of anxiety symptoms between reciprocal best friends when perceived negative features of friendship were high. These results underline the importance of teaching strategies such as problem solving that enhance friendship quality to limit the potential social contagion of anxiety symptoms.

    2009-01-01

    This highlight lecture was presented at the closing session of the Annual Congress of the European Association of Nuclear Medicine (EANM) in Munich on 15 October 2008. The Congress was a great success: there were more than 4,000 participants, and 1,597 abstracts were submitted. Of these, 1,387 were accepted for oral or poster presentation, with a rejection rate of 14%. In this article a choice was made from 100 of the 500 lectures which received the highest scores by the scientific review panel. This article outlines the major findings and trends at the EANM 2008, and is only a brief summary of the large number of outstanding abstracts presented. Among the great number of oral and poster presentations covering nearly all fields of nuclear medicine some headlines have to be defined highlighting the development of nuclear medicine in the 21st century. This review focuses on the increasing impact of molecular and multimodality imaging in the field of nuclear medicine. In addition, the question may be asked as to whether the whole spectrum of nuclear medicine is nothing other than molecular imaging and therapy. Furthermore, molecular imaging will and has to go ahead to multimodality imaging. In view of this background the review was structured according to the single steps of molecular imaging, i.e. from target description to clinical studies. The following topics are addressed: targets, radiochemistry and radiopharmacy, devices and computer science, animals and preclinical evaluations, and patients and clinical evaluations. (orig.)

  5. Optimal Face-Iris Multimodal Fusion Scheme

    Directory of Open Access Journals (Sweden)

    Omid Sharifi

    2016-06-01

    Full Text Available Multimodal biometric systems are considered a way to minimize the limitations raised by single traits. This paper proposes new schemes based on score level, feature level and decision level fusion to efficiently fuse face and iris modalities. Log-Gabor transformation is applied as the feature extraction method on face and iris modalities. At each level of fusion, different schemes are proposed to improve the recognition performance and, finally, a combination of schemes at different fusion levels constructs an optimized and robust scheme. In this study, CASIA Iris Distance database is used to examine the robustness of all unimodal and multimodal schemes. In addition, Backtracking Search Algorithm (BSA, a novel population-based iterative evolutionary algorithm, is applied to improve the recognition accuracy of schemes by reducing the number of features and selecting the optimized weights for feature level and score level fusion, respectively. Experimental results on verification rates demonstrate a significant improvement of proposed fusion schemes over unimodal and multimodal fusion methods.

    2007-01-01

    Full Text Available We present a methodology of reliability estimation in the multimodal biometric verification scenario. Reliability estimation has shown to be an efficient and accurate way of predicting and correcting erroneous classification decisions in both unimodal (speech, face, online signature and multimodal (speech and face systems. While the initial research results indicate the high potential of the proposed methodology, the performance of the reliability estimation in a multimodal setting has not been sufficiently studied or evaluated. In this paper, we demonstrate the advantages of using the unimodal reliability information in order to perform an efficient biometric fusion of two modalities. We further show the presented method to be superior to state-of-the-art multimodal decision-level fusion schemes. The experimental evaluation presented in this paper is based on the popular benchmarking bimodal BANCA database.

    Full Text Available Objective: Cardiac diseases are psycho-somatic disorders, and psychological aspects play an essential role in their initiation and exacerbation. The aim of this study was to gain appropriate knowledge in the epidemiology of co-morbid depression and anxiety disorder in cardiovascular outpatients.Method: This study is descriptive with a sample of patients attending a cardio-vascular clinic. 238 individuals were included in this study using a consecutive sampling method. The study instrument was Hospital Anxiety and Depression Scale (HADS questionnaire, which is a clinical scale for assessing anxiety and depression.Results: Of the 238 participants in this study, 93(38.7% were male and 146 (61.3% female. 28.5% of patients suffered from anxiety disorders , and 41.9% had depression. Regarding comorbid diseases such as diabetes mellitus, hyperlipidemia and hypertension, the severity of depression was just related to hypertension. There was a meaningful relationship between gender and symptoms of anxiety so that symptoms were more severe in women. Conclusion: Considering the high prevalence of depression and anxiety in patients suffering from cardio-vascular diseases, it is necessary to screen psychological disorders in patients with cardio-vascular diseases and improve their cardio-vascular health and quality of life as mush as possible.

  14. Increased discriminability of authenticity from multimodal laughter is driven by auditory information.

    Science.gov (United States)

    Lavan, Nadine; McGettigan, Carolyn

    2017-10-01

    We present an investigation of the perception of authenticity in audiovisual laughter, in which we contrast spontaneous and volitional samples and examine the contributions of unimodal affective information to multimodal percepts. In a pilot study, we demonstrate that listeners perceive spontaneous laughs as more authentic than volitional ones, both in unimodal (audio-only, visual-only) and multimodal contexts (audiovisual). In the main experiment, we show that the discriminability of volitional and spontaneous laughter is enhanced for multimodal laughter. Analyses of relationships between affective ratings and the perception of authenticity show that, while both unimodal percepts significantly predict evaluations of audiovisual laughter, it is auditory affective cues that have the greater influence on multimodal percepts. We discuss differences and potential mismatches in emotion signalling through voices and faces, in the context of spontaneous and volitional behaviour, and highlight issues that should be addressed in future studies of dynamic multimodal emotion processing.

    2014-11-01

    Full Text Available Tsuyoto Harada, Ken Inada, Kazuo Yamada, Kaoru Sakamoto, Jun Ishigooka Department of Psychiatry, Tokyo Women’s Medical University School of Medicine, Tokyo, Japan Objective: Patients often develop neuropsychiatric symptoms such as anxiety and agitation after they have started taking an antidepressant, and this is thought to be associated with a potentially increased risk of suicide. However, the incidence of antidepressant-induced jitteriness/anxiety syndrome has not been fully investigated, and little has been reported on its predictors. The aim of this study was to survey the incidence of antidepressant-induced jitteriness/anxiety syndrome and clarify its predictors in a natural clinical setting.Materials and methods: Between January 2009 and July 2012, we prospectively surveyed 301 patients who had not taken any antidepressants for 1 month before presentation, and who were prescribed antidepressants for 1 month after their initial visit. Patients were classified as developing antidepressant-induced jitteriness/anxiety syndrome if they experienced any symptoms of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, hypomania, or mania during the first month.Results: Among the 301 patients, 21 (7.0% developed antidepressant-induced jitteriness/anxiety syndrome. Major depressive disorder and a diagnosis of mood disorder in first-degree relatives of patients were significantly associated with induction of antidepressant-induced jitteriness/anxiety syndrome (odds ratio 10.2, P=0.001; odds ratio 4.65, P=0.02; respectively. However, there was no such relationship for sex, age, class of antidepressant, combined use of benzodiazepines, or diagnosis of anxiety disorder.Conclusion: The findings of this study suggest that major depressive disorder and a diagnosis of mood disorder in first-degree relatives may be clinical predictors of antidepressant-induced jitteriness/anxiety syndrome

    Full Text Available Chronic pain is commonly co-morbid with a depressive or anxiety disorder. Objective of this study is to examine the influence of depression, along with anxiety, on pain-related disability, pain intensity, and pain location in a large sample of adults with and without a depressive and/or anxiety disorder. The study population consisted of 2981 participants with a depressive, anxiety, co-morbid depressive and anxiety disorder, remitted disorder or no current disorder (controls. Severity of depressive and anxiety symptoms was also assessed. In separate multinomial regression analyses, the association of presence of depressive or anxiety disorders and symptom severity with the Chronic Pain Grade and location of pain was explored. Presence of a depressive (OR = 6.67; P<.001, anxiety (OR = 4.84; P<.001, or co-morbid depressive and anxiety disorder (OR = 30.26; P<.001 was associated with the Chronic Pain Grade. Moreover, symptom severity was associated with more disabling and severely limiting pain. Also, a remitted depressive or anxiety disorder showed more disabling and severely limiting pain (OR = 3.53; P<.001 as compared to controls. A current anxiety disorder (OR = 2.96; p<.001 and a co-morbid depressive and anxiety disorder (OR = 5.15; P<.001 were more strongly associated with cardio-respiratory pain, than gastro-intestinal or musculoskeletal pain. These findings remain after adjustment for chronic cardio respiratory illness. Patients with a current and remitted depressive and/or anxiety disorder and those with more severe symptoms have more disabling pain and pain of cardio-respiratory nature, than persons without a depressive or anxiety disorder. This warrants further research.

    This study was designed to investigate the subjective ratings of dental anxiety levels among university students enrolled at Jordan University of Science and Technology. In addition, the present study aimed to explore the sources of dental anxiety and the impact of gender on the perceived dental anxiety and the correlation between field of study and dental anxiety level. The Modified Corah Dental Anxiety Scale was used to measure dental anxiety among the study population. Six hundred subjects were recruited into the study from Jordanian undergraduate students from the faculties of Medicine, Engineering, and Dentistry. Five hundred and thirty five complete questionnaires were returned, which accounts for a response rate of 89.2%. The totals of the mean anxiety scores were the following: Medical students, 13.58%; Engineering students, 13.27% and dental students, 11.22%. About 32% of the study population has scored 15 or more. Dental students had the lowest percentage of those who scored 15 or more. Surprisingly, the medical students were responsible for the highest percentage of those who scored 15 or above. Although women demonstrated statistically higher total dental anxiety scores than men (p= 0.03), the difference between both genders was small and could be clinically insignificant. The students were anxious mostly about tooth drilling and local anesthetic injection. Lack of adequate dental health education may result in a high level of dental anxiety among non-dental university students in Jordan. Further studies are required to identify the correlates of dental anxiety among university students.

    Psychopathological analysis of the patterns of symptoms in 176 depressive in-patients disclosed in 73.3% of all patients the presence of anxiety symptoms: of these, 38.6% merely had diffuse anxiety, whereas 34.7% showed either additionally or alone specific anxiety symptoms such as phobias and panic attacks. Similar to the results obtained by dividing the patients into an "endogenous" and "neurotic" group, namely, that there was no difference between the subtypes in respect of triggering the depressive episodes by life events, or in respect of the suicide rate 30 months after discharge and in respect of a chronic course developing during the 2 years following the discharge, there was likewise no difference with regard to these criteria if the patients were subdivided into depressive patients without anxiety and those with anxiety symptoms. However, a subdivision of the depressive patients with anxiety symptoms into a group having only free-floating anxiety and a group with specific anxiety symptoms, resulted in a clear association with these criteria: If a phobia or panic attacks were present, triggering by life events was far more frequent than if there was only free-floating was more often chronic in the first group, but there was no difference in suicidality. The results indicate that it will be necessary to provide for a more differentiated classification of anxiety symptoms before deciding in clinical routine what steps to take wherever depression and anxiety symptoms are present side by side. The same applies to treatment studies.

    This study assessed the prevalence of anxiety disorders in preschool children and their associations with behavioral inhibition as a temperamental precursor. A representative sample of 1,342 children aged 4–7 years (M = 6;1, SD = 4.80) was examined with a standardized parental questionnaire, including items referring to anxiety disorders at the current age and behavioral inhibition at the age of 2 years. The total prevalence of anxiety disorders was 22.2 %. Separation anxiety (SAD) affected 7 %, social phobia (SOC) 10.7 %, specific phobia (PHOB) 9.8 % and depression/generalized anxiety (MDD/GAD) 3.4 % of children. The prevalence of most types of anxiety was higher in girls except for separation anxiety, which affected more boys. Behavioral inhibition in the second year of life was associated with all types of anxiety. Anxiety disorders are common but frequently overlooked in preschool children. Different subtypes can be differentiated and are often preceded by behavioral inhibition. Assessment, prevention and treatment of anxiety disorders are recommended in preschool children.

    assessed participants' levels of pain on a Likert scale. Of the originally enrolled participants, 68% completed the program (n = 25). The study found significant reductions in anxiety pre- and posttest using GAD-7 and identified overall and individual subscale reductions on the DASS-21. While not specifically targeted for treatment, secondary exploratory outcomes included reductions in use of anxiolytic medication and in the pain scale. The study considered the burden of use of multiple therapies upon participants; however, participation in the study's therapies was high. The findings in this pilot study suggest multimodal interventions focusing on self-care behaviors may be feasible for patients seeking therapies that are adjunct or alternative to conventional treatments. The study also suggested that this type of patient will participate in multitherapy options, and it offers support for expanding the conceptualization of and treatment for GAD by integrating CAM into existing cognitive-behavioral models.

    Full Text Available Objectives. Primary mediastinal germ cell tumors (PMGCTs are rare, which often makes them difficult to treat. Herein, we examined patients with PMGCTs who underwent multimodal treatment. Methods. We examined 6 patients (median age: 25 years, range: 19–27 years with PMGCTs who underwent multimodal treatment between April 2001 and March 2015. Three patients had seminomas, 2 patients had yolk sac tumors, and 1 patient had choriocarcinoma. The median observation period was 32.5 months (range: 8–84 months. Results. Three of the 6 patients received initial operation followed by 3-4 courses of chemotherapy (bleomycin, etoposide, and cisplatin (BEP or etoposide and cisplatin (EP. One patient developed multiple lung metastases 17 months after surgery; received salvage chemotherapy with vinblastine, ifosfamide, and cisplatin; and achieved complete remission. The remaining 3 patients received initial BEP and EP chemotherapy. Multiple lung metastases and supraclavicular lymph node metastases were detected in 2 of these patients at the initial diagnosis. The patients underwent resections to remove residual tumor after treatment, and no viable tumor cells were found. Conclusions. Reliable diagnosis and immediate multimodal treatments are necessary for patients with PMGCTs. The 6 patients treated in our hospital have never experienced recurrence after the multimodal treatment.

    2014-01-01

    We propose a robust multimodal dictionary learning method for multimodal images. Joint dictionary learning for both modalities may be impaired by lack of correspondence between image modalities in training data, for example due to areas of low quality in one of the modalities. Dictionaries learned with such non-corresponding data will induce uncertainty about image representation. In this paper, we propose a probabilistic model that accounts for image areas that are poorly corresponding between the image modalities. We cast the problem of learning a dictionary in presence of problematic image patches as a likelihood maximization problem and solve it with a variant of the EM algorithm. Our algorithm iterates identification of poorly corresponding patches and re-finements of the dictionary. We tested our method on synthetic and real data. We show improvements in image prediction quality and alignment accuracy when using the method for multimodal image registration. PMID:24505674

    Objective The aim of the study was to measure the effects on levels of anxiety in healthy teenagers caused by a temporary change of country and school during a study abroad program. Methods In a prospective study we gathered the data from six anxiety level related tests on high school participants in a study abroad program (age 15-17, n = 364, M 172, F 192). These volunteer participants were divided into two separate groups: with self-reported elevated levels of anxiety (n = 111; YES-group) and with self-reported normal levels of anxiety (n = 253; NO-group). Two control groups of schoolchildren drawn from two local schools were used for comparison (n = 100 each). Three tests were subjective, i.e. self-fill-out tests. The next three tests were objective psychological or neurophysiological tests designed to estimate reflex control, concentration and a feeling for the passage of time. Results The initial mean anxiety level score among the 364 participants was 41.5 ± 16.7 (min 16, max 80) on 5-110 scale. For the YES-group the score was 56.5 ± 15.9, and for the NO-group the score was 34.7 ± 17.4 (p = 0.05). The retesting after they had been in the same place for 7 weeks revealed that the mean anxiety level score of the participants decreased to 37.4 ± 16.9 (min 15, max 72). For the YES-group the score significantly decreased to 39.3 ± 15.5, and for the NO-group the score slightly elevated to 36.7 ± 16.4 producing similar results for both groups (p = 0.81). Conclusion A temporary change of country and school at first results in a rise in anxiety levels in about one third of participants. However, after an extended stay it falls to normal levels.

    Full Text Available n this study, we examine what and how intermediate age students learned from playing in a health-focused game-based digital learning environment, Epidemic. Epidemic is a playful interactive environment designed to deliver factual knowledge, invite critical understanding, and encourage effective self-care practices in dealing with viral contagious diseases, using a social networking interface to integrate both serious games and game-like multimodal design projects. Epidemic invites a playful approach to its deadly serious core concern – communicable disease – in order to see what happens when students are encouraged to critically approach information from multiple or contradictory perspectives. To identify what participants learned while interacting within Epidemic, we deployed two instructional and assessment models, noting the differences each instructional approach could potentially make, and what approach to assessment might help us evaluate game-based learning. We found that each approach provided importantly different perspectives on what and how students learned, and on the very meaning of student success. Recognizing that traditional assessment tools based in print-cultural literacy may prove increasingly ill-suited for assessing emergent multimodal literacies in game-based learning environments, this study seeks to contribute to a growing body of work on the development of novel assessments for learning.

Aim: This study aimed to assess the presence of anxiety symptoms in students in preexamination period. Materials and Methods: The study was carried on 619 children from Class VIII to XI. All of them were given a structured questionnaire for sociodemographic profile and Screen for Child Anxiety Related Emotional Disorders questionnaire. Association of various variables with presence of anxiety symptoms was assessed. Statistics was analyzed with SPSS version 17.0 software. Results: Totally 170 children (27.5% had anxiety symptoms, similarly the various subgroups had increased frequency compared to the known prevalence in this age group. Age, years spent in the current school, living with parents, presence of domestic stressors, and grade deterioration, all were significantly associated with increased frequency of these symptoms. Similarly, association with various subgroups is described. Conclusion: This study attempts to give evidence of increased anxiety symptoms, during preexamination phase, compared to the reported prevalence in this age group, and thus to address this becomes imperative which will improve their performance and also the mental health preventing distress along with psychological and behavioral problems.

    Alcohol is volatile and flammable liquid which is soluble substances both on polar and non polar substances that has been used in some industrial sectors. Alcohol detection method now widely used one of them is the optical fiber sensor. In this paper used fiber optic sensor based on Multimode-Single-mode-Multimode (MSM) to detect alcohol solution at a concentration range of 0-3%. The working principle of sensor utilizes the modal interference between the core modes and the cladding modes, thus make the sensor sensitive to environmental changes. The result showed that characteristic of the sensor not affect the length of the single-mode fiber (SMF). We obtain that the sensor with a length of 5 mm of single-mode can sensing the alcohol with a sensitivity of 0.107 dB/v%.

Results Of 1,650 randomly selected students, 1,350 (81.8 % completed the study. The depressive symptoms prevalence was 41 % (BDI > 9, state-anxiety 81.7 % and trait-anxiety in 85.6 % (STAI > 33. There was a positive relationship between levels of state (r = 0,591, p < 0.001 and trait (r = 0,718, p < 0.001 anxiety and depression scores. All three symptoms were positively associated with female sex and students from medical schools located in capital cities of both sexes. Tuition scholarship students had higher state-anxiety but not trait-anxiety or depression scores. Medical students with higher levels of depression and anxiety symptoms disagree more than their peers with the statements “I have adequate access to psychological support” and “There is a good support system for students who get stressed”. Conclusions The factors associated with the increase of medical students’ depression and anxiety symptoms were female sex, school location and tuition scholarship. It is interesting that tuition scholarship students showed state-anxiety, but not depression and trait-anxiety symptoms.

    2014-12-01

    Full Text Available This paper aims to identify multimodal designs for learning in diverse and developing contexts, where access to resources remains vastly unequal. Using case studies from South African education, the paper explores ways of surfacing the range of students’ resources which are often not noticed or valued in formal educational settings. The studies showcased here demonstrate how ethnographic and textually-based approaches can be combined. Opening up the semiotic space of the classroom through multimodal designs for learning is important for finding innovative ways of addressing access, diversity, and past inequalities. This is of relevance not only to South Africa, but a range of global contexts. The paper argues that multimodal designs for learning can involve interrogating the relation between ‘tradition’ and ‘modernity’; harnessing students’ creative practices as resources for pedagogy; developing metalanguages for critical reflection; creating less regulated pedagogical spaces in order to enable useful teaching and learning practices.

    This thesis is an exploratory study of Neuro-Linguistic Programming (NLP), and its capabilities to provide a technique or a composite technique that will reduce the anxiety associated with making an oral brief or presentation before a group, sometimes referred to as Communication Apprehension. The composite technique comes from NLP and Time Line Therapy, which is an extension to NLP. Student volunteers (17) from a Communications course given by the Administrative Sciences Department were taught this technique. For each volunteer, an informational oral presentation was made and videotaped before the training and another informational oral presentation made and videotaped following the training. The before and after training presentations for each individual volunteer were evaluated against criteria for communications anxiety and analyzed to determine if there was a noticeable reduction of anxiety after the training. Anxiety was reduced in all of the volunteers in this study.

    Full Text Available Abstract Background Neonatal anxiety and depression and breastfeeding cessation are significant public health problems. There is an association between maternal symptoms of anxiety and depression and early breastfeeding cessation. In earlier studies, the causality of this association was interpreted both ways; symptoms of anxiety and depression prepartum significantly impacts breastfeeding, and breastfeeding cessation significantly impacts symptoms of anxiety and depression. First, we aimed to investigate whether breastfeeding cessation is related to an increase in symptoms of anxiety and depression from pregnancy to six months postpartum. Second, we also investigated whether the proposed symptom increase after breastfeeding cessation was disproportionately high for those women already suffering from high levels of anxiety and depression during pregnancy. Methods To answer these objectives, we examined data from 42 225 women in the Norwegian Mother and Child Cohort Study (MoBa. Subjects were recruited in relation to a routine ultra-sound examination, and all pregnant women in Norway were eligible. We used data from the Medical Birth Registry of Norway and questionnaires both pre and post partum. Symptoms of anxiety and depression at six months postpartum were predicted in a linear regression analysis by WHO-categories of breastfeeding, symptoms of anxiety and depression prepartum (standardized score, and interaction terms between breastfeeding categories and prepartum symptoms of anxiety and depression. The results were adjusted for cesarean sections, primiparity, plural births, preterm births, and maternal smoking. Results First, prepartum levels of anxiety and depression were related to breastfeeding cessation (β 0.24; 95% CI 0.21-0.28, and breastfeeding cessation was predictive of an increase in postpartum anxiety and depression ( β 0.11; 95%CI 0.09-0.14.

    Traumatic injury and mental health disorders are co-associated. Early identification of depression, anxiety and stress following injury, and subsequent preventive intervention, may reduce the long-term symptoms and negative impacts associated with depression and anxiety. The purpose of the study was to determine the incidence, severity and predictors of depression, anxiety and stress in injured patients in the acute phase of care, and at six months following injury, as well as the effectiveness of an in-hospital screening tool. This descriptive longitudinal study of trauma patients was conducted at a Level 1 Metropolitan Trauma Centre in Australia over 14 months. Participants were interviewed using the Depression Anxiety Stress Scale short-form version (DASS-21) during hospital admission then at 3 and 6 months after injury. Descriptive statistics were performed to evaluate participant characteristics and incidence of depression, anxiety and stress. Correlations and logistic regression were conducted to investigate the ability of the DASS-21 to predict symptoms of depression, anxiety and stress and to investigate factors associated with depression, anxiety and stress 6 months after injury. 201 participants ranging in age (18-94 years) and injury severity participated in the baseline interview and 109 completed all 3 interviews over 6 months. Over half (54%) reported above normal scores for depression, anxiety and/or stress in at least one of the 3 time points. Intensive care unit admission and high levels of depression, anxiety and stress at 3 months post injury were predictors for high levels of depression, anxiety and stress at 6 months. Low scores for depression, anxiety and stress during admission were correlated with low scores for depression, anxiety and stress at 3 and 6 months. Depression, anxiety and stress in patients hospitalised following injury is common and should be anticipated in patients who have had an intensive care admission. Screening at 3

    We present a method of recognizing an object through a multi-mode fiber. A number of speckle patterns transmitted through a multi-mode fiber are provided to a classifier based on machine learning. We experimentally demonstrated binary classification of face and non-face targets based on the method. The measurement process of the experimental setup was random and nonlinear because a multi-mode fiber is a typical strongly scattering medium and any reference light was not used in our setup. Comparisons between three supervised learning methods, support vector machine, adaptive boosting, and neural network, are also provided. All of those learning methods achieved high accuracy rates at about 90% for the classification. The approach presented here can realize a compact and smart optical sensor. It is practically useful for medical applications, such as endoscopy. Also our study indicated a promising utilization of artificial intelligence, which has rapidly progressed, for reducing optical and computational costs in optical sensing systems.

    An increasingly large amount of multimodal content is posted on social media websites such as YouTube and Facebook everyday. In order to cope with the growth of such so much multimodal data, there is an urgent need to develop an intelligent multi-modal analysis framework that can effectively extract information from multiple modalities. In this paper, we propose a novel multimodal information extraction agent, which infers and aggregates the semantic and affective information associated with user-generated multimodal data in contexts such as e-learning, e-health, automatic video content tagging and human-computer interaction. In particular, the developed intelligent agent adopts an ensemble feature extraction approach by exploiting the joint use of tri-modal (text, audio and video) features to enhance the multimodal information extraction process. In preliminary experiments using the eNTERFACE dataset, our proposed multi-modal system is shown to achieve an accuracy of 87.95%, outperforming the best state-of-the-art system by more than 10%, or in relative terms, a 56% reduction in error rate.

    Cognitive behavioural therapy (CBT) is an effective treatment for generalized anxiety disorder, but there is still room for improvement. The aim of the present study was to examine the potential benefit of enriching CBT with kundalini yoga (Y-CBT). Participants consisted of treatment resistant clients at a community mental health clinic. A total of 32 participants enrolled in the study and 22 completed the programme. After the Y-CBT intervention, pre-post comparisons showed statistically significant improvements in state and trait anxiety, depression, panic, sleep and quality of life. Results from this preliminary study suggest that Y-CBT may have potential as a promising treatment for those suffering from generalized anxiety disorder. Yoga-enhanced cognitive behavioural therapy (Y-CBT) may be a promising new treatment for those suffering from generalized anxiety disorder. Y-CBT may also reduce depression in those suffering from generalized anxiety. Y-CBT may reduce depression and anxiety in a clinic population where clients suffer from multiple diagnoses including generalized anxiety disorder. Copyright © 2014 John Wiley & Sons, Ltd.

    Background Psychophysiological theories suggest that individuals with anxiety disorders may evidence inflexibility in their autonomic activity at rest and when responding to stressors. In addition, theories of social anxiety disorder, in particular, highlight the importance of physical symptoms. Research on autonomic activity in childhood (social) anxiety disorders, however, is scarce and has produced inconsistent findings, possibly because of methodological limitations. Method The present study aimed to account for limitations of previous studies and measured respiratory sinus arrhythmia (RSA) and heart rate (HR) using Actiheart heart rate monitors and software (Version 4) during rest and in response to a social and a non-social stressor in 60 anxious (30 socially anxious and 30 ‘other’ anxious), and 30 nonanxious sex-and age-matched 7–12 year olds. In addition, the effect of state anxiety during the tasks was explored. Results No group differences at rest or in response to stress were found. Importantly, however, with increases in state anxiety, all children, regardless of their anxiety diagnoses showed less autonomic responding (i.e., less change in HR and RSA from baseline in response to task) and took longer to recover once the stressor had passed. Limitations This study focused primarily on parasympathetic arousal and lacked measures of sympathetic arousal. Conclusion The findings suggest that childhood anxiety disorders may not be characterized by inflexible autonomic responding, and that previous findings to the contrary may have been the result of differences in subjective anxiety between anxious and nonanxious groups during the tasks, rather than a function of chronic autonomic dysregulation.

    Full Text Available Background: With the publication of the Diagnostic and Statistical Manual, Third Edition (DSM-III in 1980, anxiety disorder was first identified as a diagnostic entity. A new theoretical approach regarding aetiology of anxiety disorders came next into the view, far from Freud’s psychoanalytical pathways. The consequences were new therapeutic guidelines, including psychopharmacotherapy and the use of behavioural and cognitive psychotherapy.Methods: The paper presents a case report study of a patient with social phobia. The use of analytical oriented psychotherapy, which helped to resolve Axis I symptoms, is described.Conclusions: In spite of new therapeutic guidelines there is still a certain population of patients with the need for psychoanalytical oriented psychotherapy. If we are to surrender the Freud’s legacy to the medical history, we will weaken psychiatry as a science and will narrow our therapeutic field.

    In this study, it is aimed to determine the level of test anxiety and self-esteem in the high school students preparing for the university exam in Bitlis, Turkey, and to investigate the effect of test anxiety on self-esteem. Seven-hundred and twenty-four high school students who were preparing for the university entrance examination in Bitlis participated in the study. A questionnaire which includes socio-demographic data form, Rosenberg Self-Esteem Scale and Revised Test Anxiety Scale was prepared as an e-questionnaire for the students to fill easily and uploaded to the Bitlis State Hospital's website. Schools were called and informed for the students to fill out the e-questionnaire on the Internet. The most important findings from our study are that gender is influential on test anxiety and self-esteem score and test anxiety level are negatively correlated. It was observed that female students had more test anxiety than male students and those who had higher self-esteem had less test anxiety. Consequently, our study shows that university entrance examination creates anxiety on students and reduces self-esteem, especially in female students.

    Full Text Available Multimodal processes planning and scheduling play a pivotal role in many different domains including city networks, multimodal transportation systems, computer and telecommunication networks and so on. Multimodal process can be seen as a process partially processed by locally executed cyclic processes. In that context the concept of a Mesh-like Multimodal Transportation Network (MMTN in which several isomorphic subnetworks interact each other via distinguished subsets of common shared intermodal transport interchange facilities (such as a railway station, bus station or bus/tram stop as to provide a variety of demand-responsive passenger transportation services is examined. Consider a mesh-like layout of a passengers transport network equipped with different lines including buses, trams, metro, trains etc. where passenger flows are treated as multimodal processes. The goal is to provide a declarative model enabling to state a constraint satisfaction problem aimed at multimodal transportation processes scheduling encompassing passenger flow itineraries. Then, the main objective is to provide conditions guaranteeing solvability of particular transport lines scheduling, i.e. guaranteeing the right match-up of local cyclic acting bus, tram, metro and train schedules to a given passengers flow itineraries.

    A multi-modal piezoelectric vibration energy harvester is designed in this article. It consists of a cantilevered base beam and some upper and lower layer beams with rigid masses bonded between the beams as spacers. For a four-layer harvester subjected to random base excitations, relocating the mass positions leads to the generation of up to four close resonance frequencies over the frequency range from 10 Hz to 100 Hz with relative large power output. The harvesters are connected with a resistance decade box and the frequency response functions of the voltage and power on resistive loads are determined. The experimental results are validated with the simulation results using the finite element method. On a certain level of power output, the experimental results show that the multi-modal harvesters can generate a frequency band that is more than two times greater than the frequency band produced by a cantilevered beam harvester.

    2018-01-01

    Full Text Available This paper develops a theoretical framework for employing learning analytics in online education to trace multiple learning variations of online students by considering their potential of being multiple intelligences based on Howard Gardner’s 1983 theory of multiple intelligences. The study first emphasizes the need to facilitate students as multiple intelligences by online education systems and then suggests a framework of the advanced form of learning analytics i.e., multimodal learning analytics for tracing and facilitating multiple intelligences while they are engaged in online ubiquitous learning. As multimodal learning analytics is still an evolving area, it poses many challenges for technologists, educationists as well as organizational managers. Learning analytics make machines meet humans, therefore, the educationists with an expertise in learning theories can help technologists devise latest technological methods for multimodal learning analytics and organizational managers can implement them for the improvement of online education. Therefore, a careful instructional design based on a deep understanding of students’ learning abilities, is required to develop teaching plans and technological possibilities for monitoring students’ learning paths. This is how learning analytics can help design an adaptive instructional design based on a quick analysis of the data gathered. Based on that analysis, the academicians can critically reflect upon the quick or delayed implementation of the existing instructional design based on students’ cognitive abilities or even about the single or double loop learning design. The researcher concludes that the online education is multimodal in nature, has the capacity to endorse multiliteracies and, therefore, multiple intelligences can be tracked and facilitated through multimodal learning analytics in an online mode. However, online teachers’ training both in technological implementations and

    2014-11-01

    Advances in hardware and software have enabled the realization of clinically feasible, quantitative multimodality imaging of tissue pathophysiology. Earlier efforts relating to multimodality imaging of cancer have focused on the integration of anatomical and functional characteristics, such as PET-CT and single-photon emission CT (SPECT-CT), whereas more-recent advances and applications have involved the integration of multiple quantitative, functional measurements (for example, multiple PET tracers, varied MRI contrast mechanisms, and PET-MRI), thereby providing a more-comprehensive characterization of the tumour phenotype. The enormous amount of complementary quantitative data generated by such studies is beginning to offer unique insights into opportunities to optimize care for individual patients. Although important technical optimization and improved biological interpretation of multimodality imaging findings are needed, this approach can already be applied informatively in clinical trials of cancer therapeutics using existing tools. These concepts are discussed herein.

    2016-08-01

    Full Text Available In this study, the associations among death anxiety, spiritual tendencies, existential anxiety, and religious tendencies were examined. In addition, this study investigated whether these variables changed with respect to demographic characteristics. The study group was composed of 404 university students. Data was collected by administering the personal demographic form, Death Anxiety Scale, Existential Scale, Religious Tendency Scale, and Spirituality Scale. In line with the purpose of the study, the relational screening model and descriptive methods have been used and participants are identified as study groups. Male participants scored significantly higher than female participants. Gender was not found to have an effect on the other variables. Existential anxiety did not differ within groups with respect to having a religious education. Participants who had received a religious education had higher death anxiety and less spiritual tendencies. Motivation for religious tendencies was found to be external. According to the results, death anxiety and existential anxiety are negatively correlated; existential anxiety and spiritual tendencies are positively correlated; and religious tendencies, which have externally motivations, and spiritual tendencies are negatively correlated. Death anxiety, spiritual tendencies, and religious tendencies predict existential anxiety. As suggestions, the number of studies that examine the associations among existential anxiety, religious tendencies, and spiritual tendencies should be increased, and the quality of religious education should be discussed in detail.

    Two studies aimed to examine whether high socially anxious individuals are more likely to negatively interpret ambiguous social scenarios and facial expressions compared to low socially anxious individuals. We also examined whether interpretation bias serves as a mediator of the relationship between trait social anxiety and state anxiety responses, in particular current state anxiety, bodily sensations, and perceived probability and cost of negative evaluation pertaining to a speech task. Study 1 used ambiguous social scenarios and Study 2 used ambiguous facial expressions as stimuli to objectively assess interpretation bias. Undergraduate students with high and low social anxiety completed measures of state anxiety responses at three time points: baseline, after the interpretation bias task, and after the preparation for an impromptu speech. Results showed that high socially anxious individuals were more likely to endorse threat interpretations for ambiguous social scenarios and to interpret ambiguous faces as negative than low socially anxious individuals. Furthermore, negative interpretations mediated the relationship between trait social anxiety and perceived probability of negative evaluation pertaining to the speech task in Study 1 but not Study 2. The present studies provide new insight into the role of interpretation bias in social anxiety.

    Comorbid anxiety disorders are common in late-life depression and negatively impact treatment outcome. This study aimed to examine personality characteristics as well as early and recent life-events as possible determinants of comorbid anxiety disorders in late-life depression, taking previously examined determinants into account. Using the Composite International Diagnostic Interview (CIDI 2.0), we established comorbid anxiety disorders (social phobia (SP), panic disorder (PD), generalized anxiety disorder (GAD), and agoraphobia (AGO)) in 350 patients (aged ≥60 years) suffering from a major depressive disorder according to DSM-IV-TR criteria within the past six months. Adjusted for age, sex, and level of education, we first examined previously identified determinants of anxious depression: depression severity, suicidality, partner status, loneliness, chronic diseases, and gait speed in multiple logistic regression models. Subsequently, associations were explored with the big five personality characteristics as well as early and recent life-events. First, multiple logistic regression analyses were conducted with the presence of any anxiety disorder (yes/no) as dependent variable, where after analyses were repeated for each anxiety disorder, separately. In our sample, the prevalence rate of comorbid anxiety disorders in late-life depression was 38.6%. Determinants of comorbid anxiety disorders were a lower age, female sex, less education, higher depression severity, early traumatization, neuroticism, extraversion, and conscientiousness. Nonetheless, determinants differed across the specific anxiety disorders and lumping all anxiety disorder together masked some determinants (education, personality). Our findings stress the need to examine determinants of comorbid anxiety disorder for specific anxiety disorders separately, enabling the development of targeted interventions within subgroups of depressed patients.

    We report an acoustic multimode interference effect and self-imaging phenomena in an acoustic multimode waveguide system which consists of M parallel phononic crystal waveguides (M-PnCWs). Results show that the self-imaging principle remains applicable for acoustic waveguides just as it does for optical multimode waveguides. To achieve the dispersions and replicas of the input acoustic waves produced along the propagation direction, we performed the finite element method on M-PnCWs, which support M guided modes within the target frequency range. The simulation results show that single images (including direct and mirrored images) and N-fold images (N is an integer) are identified along the propagation direction with asymmetric and symmetric incidence discussed separately. The simulated positions of the replicas agree well with the calculated values that are theoretically decided by self-imaging conditions based on the guided mode propagation analysis. Moreover, the potential applications based on this self-imaging effect for acoustic wavelength de-multiplexing and beam splitting in the acoustic field are also presented. (paper)

    Students' attitudes and anxieties about science were measured by responses to two self-report questionnaires. The cohorts were Danish and American students at the upper secondary- and university-levels. Relationships between and among science attitudes, science anxiety, gender, and nationality were examined. Particular attention was paid to constructivist attitudes about science. These fell into at least three broad conceptual categories: Negativity of Science Toward the Individual, Subjective Construction of Knowledge, and Inherent Bias Against Women. Multigroup confirmatory factor analyses revealed that these dimensions of constructivist attitudes were equally applicable and had the same meaning in both cultures. Gender differences in mean levels of constructivist attitudes were found; these varied across the two cultures. Constructivist beliefs were associated with science anxiety, but in different ways for females and males, and for Danes and Americans. In agreement with earlier studies, females in both the US and Danish cohorts were significantly more science anxious than males, and the gender differences for the Americans were larger than those for the Danes. Findings are discussed in terms of their implications for reducing science anxiety by changing constructivist beliefs.

    The fear of negative evaluation is one of the hallmark features of social anxiety. Behavioral evidence thus far largely supports cognitive models which postulate that information processing biases in the face of socially relevant information are a key factor underlying this widespread phobia. So far only one neuroimaging study has explicitly focused on the fear of negative evaluation in social anxiety where the brain responses of social phobics were compared to healthy participants during the processing of self-referential relative to other-referential criticism, praise or neutral information. Only self-referential criticism led to stronger activations in emotion-relevant regions of the brain, such as the amygdala and medial prefrontal cortices (mPFC), in the social phobics. The objective of the current study was to determine whether these findings could be extended to subclinical social anxiety. In doing so, the specificity of this self-referential bias was also examined by including both social and non-social (physical illness-related) threat information as well as a highly health anxious control group in the experimental paradigm. The fMRI findings indicated that the processing of emotional stimuli was accompanied by activations in the amygdala and the ventral mPFC, while self-referential processing was associated with activity in regions such as the mPFC, posterior cingulate and temporal poles. Despite the validation of the paradigm, the results revealed that the previously reported behavioral and brain biases associated with social phobia could not be unequivocally extended to subclinical social anxiety. The divergence between the findings is explored in detail with reference to paradigm differences and conceptual issues.

    The prevalence of anxiety and depressive disorders in cancer patients and its associated factors in Pakistan is not known. There is a need to develop an evidence base to help introduce interventions as untreated depression and anxiety can lead to significant morbidity. We assessed the prevalence of depression and anxiety among adult outpatients with and without cancer as well as the effect of various demographic, clinical and behavioral factors on levels of depression and anxiety in cancer patients. This cross-sectional study was carried out in outpatient departments of Multan Institute of Nuclear Medicine and Radiotherapy and Nishtar Medical College Hospital, Multan. Aga Khan University Anxiety and Depression Scale (AKUADS) was used to define the presence of depression and anxiety in study participants. The sample consisted of 150 diagnosed cancer patients and 268 participants without cancer (control group). The mean age of cancer patients was 40.85 years (SD = 16.46) and median illness duration was 5.5 months, while the mean age of the control group was 39.58 years (SD = 11.74). Overall, 66.0% of the cancer patients were found to have depression and anxiety using a cutoff score of 20 on AKUADS. Among the control group, 109 subjects (40.7%) had depression and anxiety. Cancer patients were significantly more likely to suffer from distress compared to the control group (OR = 2.83, 95% CI = 1.89-4.25, P = 0.0001). Performing logistic regression analysis showed that age up to 40 years significantly influenced the prevalence of depression and anxiety in cancer patients. There was no statistically significant difference between gender, marital status, locality, education, income, occupation, physical activity, smoking, cancer site, illness duration and mode of treatment, surgery related to cancer and presence of depression and anxiety. Cancers highly associated with depression and anxiety were gastrointestinal malignancies, chest tumors and breast cancer. This study

    This paper presents an advanced design concept for a piezoelectric energy harvesting (EH), referred to as multimodal EH skin. This EH design facilitates the use of multimodal vibration and enhances power harvesting efficiency. The multimodal EH skin is an extension of our previous work, EH skin, which was an innovative design paradigm for a piezoelectric energy harvester: a vibrating skin structure and an additional thin piezoelectric layer in one device. A computational (finite element) model of the multilayered assembly - the vibrating skin structure and piezoelectric layer - is constructed and the optimal topology and/or shape of the piezoelectric layer is found for maximum power generation from multiple vibration modes. A design rationale for the multimodal EH skin was proposed: designing a piezoelectric material distribution and external resistors. In the material design step, the piezoelectric material is segmented by inflection lines from multiple vibration modes of interests to minimize voltage cancellation. The inflection lines are detected using the voltage phase. In the external resistor design step, the resistor values are found for each segment to maximize power output. The presented design concept, which can be applied to any engineering system with multimodal harmonic-vibrating skins, was applied to two case studies: an aircraft skin and a power transformer panel. The excellent performance of multimodal EH skin was demonstrated, showing larger power generation than EH skin without segmentation or unimodal EH skin.

  11. Generalised anxiety disorder

    Full Text Available Generalised anxiety disorder is characterised by persistent, excessive and difficult-to-control worry, which may be accompanied by several psychic and somatic symptoms, including suicidality. Generalized anxiety disorder is the most common psychiatric disorder in the primary care, although it is often underrecognised and undertreated. Generalized anxiety disorder is typically a chronic condition with low short- and medium-term remission rates. Clinical presentations often include depression, somatic illness, pain, fatigue and problems sleeping. The evaluation of prognosis is complicated by frequent comorbidity with other anxiety disorders and depression, which worsen the long-term outcome and accompanying burden of disability. The two main treatments for generalised anxiety disorder are medications and psychotherapy. Selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors represent first-line psychopharmacologic treatment for generalised anxiety disorder. The most extensively studied psychotherapy for anxiety is cognitive behavioural therapy which has demonstrated efficacy throughout controlled studies.

    Previous research suggests that anxiety may play a large role in the symptoms of vaginismus. We aimed to (i) determine the degree of self-reported general anxiety in women with vaginismus; and (ii) establish whether general anxiety is a consequence of the condition or a predisposing factor. Participants reported state and trait anxiety, five-factor personality scores, history of anxiety disorders, and their perceptions of their symptoms and history. We compared responses of 244 self-identified women with vaginismus with a control group of 101 women using an online questionnaire. The women with vaginismus were higher in trait anxiety and neuroticism, and lower in extraversion, than the controls. There was also a trend toward a greater prevalence of diagnosed anxiety disorders in the vaginismus group. Levels of state anxiety were high among the women with vaginismus, particularly when they felt unsupported by their partners or pressured to cure the condition. Levels of general anxiety are elevated among women with vaginismus and the data suggest that anxiety-proneness may be a predisposing factor for the condition. We conclude that although vaginismus is a multidimensional condition, it may have common predisposing factors with anxiety disorders.

    Fluorescence microscopy, utilizing fluorescence labeling, has the capability to observe intercellular changes which transmitted and reflected light microscopy techniques cannot resolve. However, the parts without fluorescence labeling are not imaged. Hence, the processes simultaneously happen in these parts cannot be revealed. Meanwhile, fluorescence imaging is 2D imaging where information in the depth is missing. Therefore the information in labeling parts is also not complete. On the other hand, quantitative phase imaging is capable to image cells in 3D in real time through phase calculation. However, its resolution is limited by the optical diffraction and cannot observe intercellular changes below 200 nanometers. In this work, fluorescence imaging and quantitative phase imaging are combined to build a multimodal imaging system. Such system has the capability to simultaneously observe the detailed intercellular phenomenon and 3D cell morphology. In this study the proposed multimodal imaging system is used to observe the cell behavior in the cell apoptosis. The aim is to highlight the limitations of fluorescence microscopy and to point out the advantages of multimodal quantitative phase and fluorescence imaging. The proposed multimodal quantitative phase imaging could be further applied in cell related biomedical research, such as tumor.

    Studies investigating depression and anxiety levels in mothers of children with CP and related factors are limited, and controversial findings are reported in these studies. The study was aimed to determine depression and anxiety levels in mothers of children with cerebral palsy (CP) and to define factors related to depression and anxiety levels. A descriptive study. Outpatient physical medicine and rehabilitation clinic of an education and research hospital. The study was composed of two groups: group 1, 116 mothers of children with CP and group 2, 114 mothers of healthy children. Mothers of children with spastic-type CP were included into group 1. Functional levels in children with CP were investigated with The Gross Motor Function Classification System (GMFCS). Depression levels of mothers in both groups were assessed with Beck Depression Inventory (BDI), and anxiety levels with Beck Anxiety Inventory (BAI). BDI and BAI scores were statistically and significantly higher in group 1, compared to group 2. Among mothers in group 1, a positive correlation was determined between GMFCS score, and depression and anxiety levels. However, no correlation was detected between depression and anxiety levels, and body involvement of CP, education status, age and economic level among patients. In logistic regression analysis, the most significant risk factors of depressive symptoms were detected to be GMFCS score and speech defects. Our findings indicate that depression and anxiety levels of mothers with CP children are higher than those with healthy children and associated with speech defects and functional disability levels in children with CP. Healthcare professionals should take into account that depression and anxiety levels may be higher in mothers of children with CP. For an effective rehabilitation program related to children with CP, depression and anxiety levels in mothers of such children should be taken into account, and mothers should closely be followed and if

    Anxiety is linked to a number of medical conditions, yet few studies have examined how symptom severity relates to medical comorbidity. The current study assessed associations between severity of anxiety and depression and the presence of medical conditions in adults diagnosed with anxiety disorders. Nine-hundred eighty-nine patients diagnosed with panic, generalized anxiety, social anxiety, and posttraumatic stress disorders reported on the severity of anxiety and depressive symptoms and on diagnoses of 11 medical conditions. Severity of anxiety and depressive symptoms was strongly associated with having more medical conditions over and above control variables, and the association was as strong as that between BMI and disease. Odds of having asthma, heart disease, back problems, ulcer, migraine headache and eyesight difficulties also increased as anxiety and depressive symptom severity increased. Anxiety symptoms were independently associated with ulcer, whereas depressive symptoms were independently associated with heart disease, migraine, and eyesight difficulties. These findings add to a growing body of research linking anxiety disorders with physical health problems and indicate that anxiety and depressive symptoms deserve greater attention in their association with disease.

    Full Text Available Purpose: The purpose of study is to solve the multi-modal transportation routing planning problem that aims to select an optimal route to move a consignment of goods from its origin to its destination through the multi-modal transportation network. And the optimization is from two viewpoints including cost and time. Design/methodology/approach: In this study, a bi-objective mixed integer linear programming model is proposed to optimize the multi-modal transportation routing planning problem. Minimizing the total transportation cost and the total transportation time are set as the optimization objectives of the model. In order to balance the benefit between the two objectives, Pareto optimality is utilized to solve the model by gaining its Pareto frontier. The Pareto frontier of the model can provide the multi-modal transportation operator (MTO and customers with better decision support and it is gained by the normalized normal constraint method. Then, an experimental case study is designed to verify the feasibility of the model and Pareto optimality by using the mathematical programming software Lingo. Finally, the sensitivity analysis of the demand and supply in the multi-modal transportation organization is performed based on the designed case. Findings: The calculation results indicate that the proposed model and Pareto optimality have good performance in dealing with the bi-objective optimization. The sensitivity analysis also shows the influence of the variation of the demand and supply on the multi-modal transportation organization clearly. Therefore, this method can be further promoted to the practice. Originality/value: A bi-objective mixed integer linear programming model is proposed to optimize the multi-modal transportation routing planning problem. The Pareto frontier based sensitivity analysis of the demand and supply in the multi-modal transportation organization is performed based on the designed case.

    Full Text Available Abstract Background Perinatal research on anxiety and depression has primarily focused on mothers. We have limited knowledge of fathers’ anxiety during the perinatal period yet there is evidence that the parenting capacity of a person can be compromised by anxiety and depression. The purpose of this paper is to identify the impact of a father inclusive intervention on perinatal anxiety and depression. The prime focus of the intervention was to provide education and support to fathers of breastfeeding partners with the aim of increasing both initiation and duration of breastfeeding. Methods A repeated measures cohort study was conducted during a RCT that was implemented across eight public maternity hospitals in Perth, Western Australia between May 2008 and June 2009. A baseline questionnaire which included the Hospital Anxiety and Depression Scale (HADS was administered to all participants on the first night of their hospital based antenatal education program and was repeated at six weeks postnatal. SPSS version 17 was used for reporting descriptive results. Results The mean anxiety levels at baseline for the fathers in the intervention group (n=289 and control group (n=244 were 4.58 and 4.22 respectively. At 6 weeks postnatal (only matched pairs, intervention and control group were 3.93 and 3.79. More intervention group fathers self-rated less anxiety compared to the fathers in the control group from baseline to post test (p=0.048. Depression scores for intervention fathers at baseline (mean =1.09 and at six weeks (mean=1.09 were very similar to fathers in the control group at baseline (mean=1.11 and at six weeks (mean =1.07 with no significant changes. Conclusions Both intervention and control group fathers experienced some anxiety prior to the birth of their baby, but this was rapidly reduced at six weeks. Paternal anxiety is common to new fathers and providing them with information and strategies for problem-solving can increase their

    Full Text Available There is currently no widely accepted instrument for measuring preoperative anxiety. The objective of this study was to develop a simple visual facial anxiety scale (VFAS for assessing acute preoperative anxiety.The initial VFAS was comprised of 11 similarly styled stick-figure reflecting different types of facial expressions (Fig 1. After obtaining IRB approval, a total of 265 participant-healthcare providers (e.g., anesthesiologists, anesthesiology residents, and perioperative nurses were recruited to participate in this study. The participants were asked to: (1 rank the 11 faces from 0-10 (0 = no anxiety, while 10 = highest anxiety and then to (2 match one of the 11 facial expression with a numeric verbal rating scale (NVRS (0 = no anxiety and 10 = highest level of anxiety and a specific categorical level of anxiety, namely no anxiety, mild, mild-moderate, moderate, moderate-high or highest anxiety. Based on these data, the Spearman correlation and frequencies of the 11 faces in relation to the 11-point numerical anxiety scale and 6 categorical anxiety levels were calculated. The highest frequency of a face assigned to a level of the numerical anxiety scale resulted in a finalized order of faces corresponding to the 11-point numeric rating scale.The highest frequency for each of the NVRS anxiety scores were as follow: A0, A1, A2, A3, A4, A5, A7, A6, A8, A9 and A10 (Fig 2. For the six categorical anxiety levels, a total of 260 (98.1% participants chose the face A0 as representing 'no' anxiety, 250 (94.3% participants chose the face A10 as representing 'highest' anxiety and 147 (55.5% participants chose the face A8 as representing 'moderate-high' anxiety. Spearman analysis showed a significant correlation between the faces A3 and A5 assigned to the mild-moderate anxiety category (r = 0.58, but A5 was ultimately chosen due to its higher frequency compared to the frequency of A3 (30.6% vs 24.9%(Fig 3.

    Full Text Available Objective. To examine the association between anxiety and weight change in a multiethnic cohort followed for approximately 10 years. Methods. The study population consisted of participants of the multiethnic study of atherosclerosis who met specified inclusion criteria (n = 5,799. Weight was measured at baseline and four subsequent follow-up exams. Anxiety was analyzed as sex-specific anxiety quartiles (QANX. The relationship between anxiety level and weight change was examined using a mixed-effect model with weight as the dependent variable, anxiety and time as the independent variables, and adjusted for covariates. Results. Average annual weight change (range was −0.17 kg (−6.04 to 4.38 kg for QANX 1 (lowest anxiety, −0.16 kg (−10.71 to 4.45 kg for QANX 2, −0.15 kg (−8.69 to 6.39 kg for QANX 3, and −0.20 kg (−7.12 to 3.95 kg for QANX 4 (highest anxiety. No significant association was noted between QANX and weight change. However, the highest QANX was associated with a −2.48 kg (95% CI = −3.65, −1.31 lower baseline weight compared to the lowest QANX after adjustment for all covariates. Conclusions. Among adults, age 45–84, higher levels of anxiety, defined by the STPI trait anxiety scale, are associated with lower average baseline weight but not with weight change.

    Children and adolescents seem to suffer from anxiety disorders at rates similar to adults. Interestingly, anxiety symptoms appear to generally decline over time within children as evidenced by lower rates in early and middle adolescence. There is some evidence that there may be heterogeneous subpopulations of adolescent children with different trajectories of anxiety symptoms, including a class of adolescents with elevated levels of anxiety that do not dissipate over time. Anxiety sensitivity has been identified as an important risk factor in the development of anxiety psychopathology. This study prospectively examined the development of anxiety symptoms in a sample of 277 adolescents (M age = 11.52; 44 % female, 56 % male) over a 3 year period including the influence of anxiety sensitivity on this development. Further, this study investigated whether there were distinct classes of adolescents based on their anxiety symptom trajectories and including anxiety sensitivity as a predictor. Consistent with other reports, findings indicated an overall decline in anxiety symptoms over time in the sample. However, three classes of adolescents were found with distinct anxiety symptom trajectories and anxiety sensitivity was an important predictor of class membership. Adolescents with elevated anxiety sensitivity scores were more likely to be classified as having high and increasing anxiety symptoms over time versus having moderate to low and decreasing anxiety symptoms over time. There are important implications for identification of adolescents and children who are at risk for the development of an anxiety disorder.

    Full Text Available Background. Preoperative anxiety complicates treatment and requires assessment by nurses in children. Children, with or without disability, are helped when pictures are used to support communication. The purpose of this pilot study was to test the reliability and validity of the modified short State-Trait Anxiety Inventory (STAI using a modified Talking Mats method in children undergoing day surgeries. Method. A modified short STAI with pictorial support along the lines of the Talking Mats method was pre- and postoperatively administered to 42 typically developing children aged three to nine years. The parents assessed the children’s anxiety, simultaneously and independently, by scoring the short STAI by proxy. Results. The modified short STAI showed moderate internal consistency and good construct validity in the age group seven to nine years. Conclusions. The results of this study support the use of the instrument for self-reports in children aged seven to nine years. Future research will explore the possibilities of also using this instrument for children with cognitive and communicative difficulties.

    Hypnosis is classically presented as a useful psychotherapy for various psychiatric conditions, especially in the field of stress and anxiety. However, its place in therapeutic of chronic anxiety disorders remains unclear and questioned. Thus, the goal of this systematic review was to analyse the papers reporting clinical data on the efficacy of hypnosis in anxiety disorders. A literature search was conducted on Pubmed to retrieve all original papers, published between 1980 and 2015, reporting clinical information on the efficacy of hypnosis in six categories of anxiety disorders. Each paper has been assessed from a methodological point of view, and the results have been analysed. Only three controlled studies have been identified, one in panic disorder and two in post-traumatic stress disorder (PTSD). The other papers related open-design studies (4 articles), or single case reports (20 articles). The controlled study conducted in panic disorder suggested that the combination of hypnosis with cognitive-behavior therapy was not an effective strategy, and this negative result was also obtained in one of the studies conducted in PTSD. The third study, including 48 Indonesian children with PTSD, showed a significant improvement with a specific hypnosis technique adapted to the local culture. Other papers related also positive results but in non-controlled studies or in case reports, their conclusions cannot be generalized. To date, evidence is negative or insufficient to support the efficacy of hypnosis in chronic anxiety disorders, in any categories whatsoever - including phobia or PTSD. Specific further studies are needed to identify some potential profiles predictive of response to hypnosis in these conditions. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Anxiety disorders are the most prevalent mental health condition in Australia. In addition, there are many people who experience problematic anxiety symptoms who do not receive an anxiety disorder diagnosis but require treatment. As herbal medicine use is popular in Australia, and little is known about how adults experiencing anxiety are using these medicines, this study aimed to identify how Australian adults who experience anxiety are using herbal medicines. An online cross-sectional descriptive study was conducted using purposive convenience sampling to recruit Australian adults who have experienced anxiety symptoms and have used herbal medicines (N = 400). Descriptive statistics, chi-square test of contingency, analysis of variance, and simple logistic regression was used to analyse the data. Eighty two percent of participants experienced anxiety symptoms in the previous 12 months, with 47% reporting having previously been diagnosed with an anxiety disorder. In addition, 72.8% had used herbal medicines specifically for anxiety symptoms in their lifetime, while 55.3% had used prescribed pharmaceuticals, with 27.5% having used herbal medicines concurrently with prescribed pharmaceuticals. The Internet and family and friends were the most frequently used sources of information about herbal medicines. Forty eight percent of participants did not disclose their herbal medicine use to their doctor. Herbal medicines are being used by adults with anxiety and are commonly self-prescribed for anxiety symptoms. Health practitioners who are experts in herbal medicine prescribing are consulted infrequently. In addition, herbal medicine use is often not disclosed to health practitioners. These behaviours are concerning as people may not be receiving the most suitable treatments, and their use of herbal medicines may even be dangerous. It is critical we develop a better understanding of why people are using these medicines, and how we can develop improved health literacy

  11. Empowering Prospective Teachers to Become Active Sense-Makers: Multimodal Modeling of the Seasons

    Situating science concepts in concrete and authentic contexts, using information and communications technologies, including multimodal modeling tools, is important for promoting the development of higher-order thinking skills in learners. However, teachers often struggle to integrate emergent multimodal models into a technology-rich informal learning environment. Our design-based research co-designs and develops engaging, immersive, and interactive informal learning activities called "Embodied Modeling-Mediated Activities" (EMMA) to support not only Singaporean learners' deep learning of astronomy but also the capacity of teachers. As part of the research on EMMA, this case study describes two prospective teachers' co-design processes involving multimodal models for teaching and learning the concept of the seasons in a technology-rich informal learning setting. Our study uncovers four prominent themes emerging from our data concerning the contextualized nature of learning and teaching involving multimodal models in informal learning contexts: (1) promoting communication and emerging questions, (2) offering affordances through limitations, (3) explaining one concept involving multiple concepts, and (4) integrating teaching and learning experiences. This study has an implication for the development of a pedagogical framework for teaching and learning in technology-enhanced learning environments—that is empowering teachers to become active sense-makers using multimodal models.

    2017-01-01

    Anxiety disorders are highly prevalent psychiatric disorders often comorbid with depression and substance abuse. Twin studies have shown that anxiety disorders are moderately heritable. Yet, genome-wide association studies (GWASs) have failed to identify gene(s) significantly associated with diagnosis suggesting a strong role for environmental factors and the epigenome. A number of anxiety disorder subtypes are considered "stress related." A large focus of research has been on the epigenetic and anxiety-like behavioral consequences of stress. Animal models of anxiety-related disorders have provided strong evidence for the role of stress on the epigenetic control of the hypothalamic-pituitary-adrenal (HPA) axis and of stress-responsive brain regions. Neuroepigenetics may continue to explain individual variation in susceptibility to environmental perturbations and consequently anxious behavior. Behavioral and pharmacological interventions aimed at targeting epigenetic marks associated with anxiety may prove fruitful in developing treatments.

  14. Advanced Multimodal Solutions for Information Presentation

    2018-01-01

    High-workload, fast-paced, and degraded sensory environments are the likeliest candidates to benefit from multimodal information presentation. For example, during EVA (Extra-Vehicular Activity) and telerobotic operations, the sensory restrictions associated with a space environment provide a major challenge to maintaining the situation awareness (SA) required for safe operations. Multimodal displays hold promise to enhance situation awareness and task performance by utilizing different sensory modalities and maximizing their effectiveness based on appropriate interaction between modalities. During EVA, the visual and auditory channels are likely to be the most utilized with tasks such as monitoring the visual environment, attending visual and auditory displays, and maintaining multichannel auditory communications. Previous studies have shown that compared to unimodal displays (spatial auditory or 2D visual), bimodal presentation of information can improve operator performance during simulated extravehicular activity on planetary surfaces for tasks as diverse as orientation, localization or docking, particularly when the visual environment is degraded or workload is increased. Tactile displays offer a third sensory channel that may both offload information processing effort and provide a means to capture attention when urgently required. For example, recent studies suggest that including tactile cues may result in increased orientation and alerting accuracy, improved task response time and decreased workload, as well as provide self-orientation cues in microgravity on the ISS (International Space Station). An important overall issue is that context-dependent factors like task complexity, sensory degradation, peripersonal vs. extrapersonal space operations, workload, experience level, and operator fatigue tend to vary greatly in complex real-world environments and it will be difficult to design a multimodal interface that performs well under all conditions.

    Clinically significant separation anxiety disorder in childhood leads to adult panic disorder and other anxiety disorders. The prevailing pathophysiological model of anxiety disorders, which emphasizes extinction deficits of fear-conditioned responses, does not fully consider the role of separation anxiety. Pathological early childhood attachments have far-reaching consequences for the later adult ability to experience and internalize positive relationships in order to develop mental capacities for self-soothing, anxiety tolerance, affect modulation, and individuation. Initially identified in attachment research, the phenomenon of separation anxiety is supported by animal model, neuroimaging, and genetic studies. A role of oxytocin is postulated. Adults, inured to their anxiety, often do not identify separation anxiety as problematic, but those who develop anxiety and mood disorders respond more poorly to both pharmacological and psychotherapeutic interventions. This poorer response may reflect patients' difficulty in forming and maintaining attachments, including therapeutic relationships. Psychotherapies that focus on relationships and separation anxiety may benefit patients with separation anxiety by using the dyadic therapist-patient relationship to recapture and better understand important elements of earlier pathological parent-child relationships.

    Full Text Available Students' performance anxiety can impact negatively on the effectiveness of medical education reform, including performance in problem-based learning (PBL and in using English in discussion. This study aimed to investigate the nature of performance anxiety among Taiwanese medical students in an English-language PBL group. Eighteen Taiwanese, one American and four Asian medical students who were attending an international PBL workshop were enrolled. A questionnaire seeking demographic data and experience in use of PBL and eight questions evaluating performance anxiety were administered. The performance anxiety of Taiwanese medical students was compared to that of the Asians and the one American. Frequencies of each performance anxiety were calculated. The results suggested that the Taiwanese students showed more anxiety than the one student from the United States, but less than other Asian students. The acts of giving a report, being the center of attention, and talking in the PBL group were the most common situations related to anxiety in PBL groups. Using English and working in a new PBL environment are possible sources of anxiety. The presence of anxiety among the Taiwanese medical students in English PBL groups implies the necessity for developing an effective strategy to deal with students' performance anxiety.

    Full Text Available This research proposes a multimodal multifeature biometric system for human recognition using two traits, that is, palmprint and iris. The purpose of this research is to analyse integration of multimodal and multifeature biometric system using feature level fusion to achieve better performance. The main aim of the proposed system is to increase the recognition accuracy using feature level fusion. The features at the feature level fusion are raw biometric data which contains rich information when compared to decision and matching score level fusion. Hence information fused at the feature level is expected to obtain improved recognition accuracy. However, information fused at feature level has the problem of curse in dimensionality; here PCA (principal component analysis is used to diminish the dimensionality of the feature sets as they are high dimensional. The proposed multimodal results were compared with other multimodal and monomodal approaches. Out of these comparisons, the multimodal multifeature palmprint iris fusion offers significant improvements in the accuracy of the suggested multimodal biometric system. The proposed algorithm is tested using created virtual multimodal database using UPOL iris database and PolyU palmprint database.

    Full Text Available Background and Objectives: Considering the painfulness of labor and its resulting anxiety, and also, complications such as uterine dysfunction, prolonged labor, and unpleasant memories, the present study was performed aimed to investigate the effect of peppermint aroma on the level of pain and anxiety in the first stage of labor in nulliparous women.Methods: This research was done as a clinical trial study on 128 nulliparous women assigned into two groups (64 subjects in aromatherapy group and 64 subjects in control group. In aromatherapy group, mixtures containing 0.2ml essence of peppermint and 2ml normal saline impregnated gauze, and in the control group, only 2ml normal saline impregnated gauze were attached to their dress collar, and the administration was repeated every 30 minutes. Level of anxiety was measured in dilatations 3-4 and 8-10cm and the intensity of pain in dilatations 4-5, 6-7, and 8-10cm. The data were collected through demographic and obstetric questionnaire, observation checklist, spielberger anxiety questionnaire, and pain numerical rating scale. Results: In this study, the age, job, education, and gestational age were the same in both groups. Also, the level of anxiety was the same in both groups before the intervention, but after the intervention, anxiety level decreased in intervention group compared to control group (p<0.001. The mean pain score in the dilatations 4-5, 6-7, and 8-10cm decreased in intervention group compared to control group (p<0.001 for all.Conclusion: Aromatherapy with peppermint essence is recommended for the reduction of pain and anxiety level during labor due to its inexpensiveness, ease and non-invasiveness.

    A large proportion of students identify statistics courses as the most anxiety-inducing courses in their curriculum. Many students feel impaired by feelings of state anxiety in the examination and therefore probably show lower achievements. The study investigates how statistics anxiety, attitudes (e.g., interest, mathematical self-concept) and trait anxiety, as a general disposition to anxiety, influence experiences of anxiety as well as achievement in an examination. Participants were 284 undergraduate psychology students, 225 females and 59 males. Two weeks prior to the examination, participants completed a demographic questionnaire and measures of the STARS, the STAI, self-concept in mathematics, and interest in statistics. At the beginning of the statistics examination, students assessed their present state anxiety by the KUSTA scale. After 25 min, all examination participants gave another assessment of their anxiety at that moment. Students' examination scores were recorded. Structural equation modelling techniques were used to test relationships between the variables in a multivariate context. Statistics anxiety was the only variable related to state anxiety in the examination. Via state anxiety experienced before and during the examination, statistics anxiety had a negative influence on achievement. However, statistics anxiety also had a direct positive influence on achievement. This result may be explained by students' motivational goals in the specific educational setting. The results provide insight into the relationship between students' attitudes, dispositions, experiences of anxiety in the examination, and academic achievement, and give recommendations to instructors on how to support students prior to and in the examination. © 2012 The British Psychological Society.

    Improving mechanisms to detect adverse drug reactions (ADRs) is key to strengthening post-marketing drug safety surveillance. Signal detection is presently unimodal, relying on a single information source. Multimodal signal detection is based on jointly analyzing multiple information sources. Building on, and expanding the work done in prior studies, the aim of the article is to further research on multimodal signal detection, explore its potential benefits, and propose methods for its construction and evaluation. Four data sources are investigated; FDA's adverse event reporting system, insurance claims, the MEDLINE citation database, and the logs of major Web search engines. Published methods are used to generate and combine signals from each data source. Two distinct reference benchmarks corresponding to well-established and recently labeled ADRs respectively are used to evaluate the performance of multimodal signal detection in terms of area under the ROC curve (AUC) and lead-time-to-detection, with the latter relative to labeling revision dates. Limited to our reference benchmarks, multimodal signal detection provides AUC improvements ranging from 0.04 to 0.09 based on a widely used evaluation benchmark, and a comparative added lead-time of 7-22 months relative to labeling revision dates from a time-indexed benchmark. The results support the notion that utilizing and jointly analyzing multiple data sources may lead to improved signal detection. Given certain data and benchmark limitations, the early stage of development, and the complexity of ADRs, it is currently not possible to make definitive statements about the ultimate utility of the concept. Continued development of multimodal signal detection requires a deeper understanding the data sources used, additional benchmarks, and further research on methods to generate and synthesize signals.

    Summary Background Depression and anxiety disorders are highly comorbid conditions and a worldwide disease burden; however, large-scale studies delineating their association are scarce. In this retrospective study, we aimed to assess the effect of severe anxiety disorders on the risk and course of depression. Methods We did a population-based cohort study with prospectively gathered data in Denmark using data from three Danish population registers: The Danish Civil Registration System, the Danish Psychiatric Central Register, and the Danish National Hospital Registry. We selected the cohort from people born in Denmark between Jan 1, 1955, and Dec 31, 2002, who we followed up from Jan 1, 1994, to Dec 31, 2012. The cohort was restricted to individuals with known parents. First, we investigated the effect of specific anxiety diagnoses on risk of single depressive episodes and recurrent depressive disorder. Second, we investigated the effect of comorbid anxiety on risk of readmission for depression, adjusting for sex, age, calendar year, parental age, place at residence at time of birth, and the interaction of age with sex. Findings We included 3 380 059 individuals in our study cohort. The adjusted incidence rate ratio (IRR) for single depressive episodes was 3·0 (95% CI 2·8–3·1, pdepressive disorder was 5·0 (4·8–5·2) in patients with severe anxiety disorders compared with the general population. Compared with control individuals, the offspring of parents with anxiety disorders were more likely to be diagnosed with single depressive episodes (1·9, 1·8–2·0) or recurrent depressive disorder (2·1, 1·9–2·2). Comorbid anxiety increased the readmission rates in both patients with single depressive episodes and patients with recurrent depressive disorder. Interpretation Severe anxiety constitutes a significant risk factor for depression. Focusing on specific anxiety disorders might help to identify individuals at risk of depression, thereby providing new

    Full Text Available Abstract Background Multiple studies have demonstrated that rates of smoking and nicotine dependence are increased in individuals with anxiety disorders. However, significant variability exists in the epidemiological literature exploring this relationship, including study design (cross-sectional versus prospective, the population assessed (random sample versus clinical population and diagnostic instrument utilized. Methods We undertook a systematic review of population-based observational studies that utilized recognized structured clinical diagnostic criteria (Diagnostic and Statistical Manual of Mental Disorders (DSM or International Classification of Diseases (ICD for anxiety disorder diagnosis to investigate the relationship between cigarette smoking, nicotine dependence and anxiety disorders. Results In total, 47 studies met the predefined inclusion criteria, with 12 studies providing prospective information and 5 studies providing quasiprospective information. The available evidence suggests that some baseline anxiety disorders are a risk factor for initiation of smoking and nicotine dependence, although the evidence is heterogeneous and many studies did not control for the effect of comorbid substance use disorders. The identified evidence however appeared to more consistently support cigarette smoking and nicotine dependence as being a risk factor for development of some anxiety disorders (for example, panic disorder, generalized anxiety disorder, although these findings were not replicated in all studies. A number of inconsistencies in the literature were identified. Conclusions Although many studies have demonstrated increased rates of smoking and nicotine dependence in individuals with anxiety disorders, there is a limited and heterogeneous literature that has prospectively examined this relationship in population studies using validated diagnostic criteria. The most consistent evidence supports smoking and nicotine dependence as

    2009-12-12

    Over the past few years we have been developing an expressive embodied conversational agent system. In particular, we have developed a model of multimodal behaviours that includes dynamism and complex facial expressions. The first feature refers to the qualitative execution of behaviours. Our model is based on perceptual studies and encompasses several parameters that modulate multimodal behaviours. The second feature, the model of complex expressions, follows a componential approach where a new expression is obtained by combining facial areas of other expressions. Lately we have been working on adding temporal dynamism to expressions. So far they have been designed statically, typically at their apex. Only full-blown expressions could be modelled. To overcome this limitation, we have defined a representation scheme that describes the temporal evolution of the expression of an emotion. It is no longer represented by a static definition but by a temporally ordered sequence of multimodal signals.

    Optical microspectroscopic tools reveal great potential for dermatologic diagnostics in the clinical day-to-day routine. To enhance the diagnostic value of individual nonlinear optical imaging modalities such as coherent anti-Stokes Raman scattering (CARS), second harmonic generation (SHG) or two-photon excited fluorescence (TPF), the approach of multimodal imaging has recently been developed. Here, we present an application of nonlinear optical multimodal imaging with Raman-scattering microscopy to study sizable human-tissue cross-sections. The samples investigated contain both healthy tissue and various skin tumors. This contribution details the rich information content, which can be obtained from the multimodal approach: While CARS microscopy, which - in contrast to spontaneous Raman-scattering microscopy - is not hampered by single-photon excited fluorescence, is used to monitor the lipid and protein distribution in the samples, SHG imaging selectively highlights the distribution of collagen structures within the tissue. This is due to the fact, that SHG is only generated in structures which lack inversion geometry. Finally, TPF reveals the distribution of autofluorophores in tissue. The combination of these techniques, i.e. multimodal imaging, allows for recording chemical images of large area samples and is - as this contribution will highlight - of high clinically diagnostic value.

    to understand the trends in, and relationships between, maternal stress, depressive symptoms and anxiety in pregnancy and post partum. a prospective longitudinal survey study was undertaken to explore maternal psychological distress throughout the perinatal period. The participants were recruited after 24 completed weeks of gestation, and were followed-up monthly until one month post partum (four surveys in total). participants were recruited from a single hospital in southern Taiwan, and asked to complete questionnaires in the hospital waiting area. inclusion criteria were: age ≥18 years, able to read and write Chinese, ≥24 weeks of gestation, singleton pregnancy and no pregnancy complications (including a diagnosis of antenatal depression or anxiety disorder). In total, 197 women completed all four surveys (response rate 74.62%). stress was measured with the 10-item Perceived Stress Scale, depressive symptoms were measured with the Center for Epidemiologic Studies' Depression scale, and anxiety was measured with the Zung Self-reported Anxiety Scale. Participants were followed-up at four time points: T1 (25-29 gestational weeks), T2 (30-34 gestational weeks), T3 (>34 gestational weeks) and T4 (4-6 weeks post partum). Appointments for data collection were made in accordance with the participants' antenatal and postnatal check-ups. The three types of maternal distress had different courses of change throughout the perinatal period, as levels of depressive symptoms remained unchanged, anxiety levels increased as gestation advanced but declined after birth, and stress decreased gradually during pregnancy but returned to the T1 level after birth. There was a low to high degree of correlation in maternal stress, depressive symptoms and anxiety in pregnancy and post partum. around one-quarter of the study participants had depressive symptoms during pregnancy and post partum. Stress and anxiety showed opposing courses during the perinatal period. Regardless of the

    Researchers conducted extensive investigations of hallucinogens in the 1950s and 1960s. By the early 1970s, however, political and cultural pressures forced the cessation of all projects. This investigation reexamines a potentially promising clinical application of hallucinogens in the treatment of anxiety reactive to advanced-stage cancer. To explore the safety and efficacy of psilocybin in patients with advanced-stage cancer and reactive anxiety. A double-blind, placebo-controlled study of patients with advanced-stage cancer and anxiety, with subjects acting as their own control, using a moderate dose (0.2 mg/kg) of psilocybin. A clinical research unit within a large public sector academic medical center. Twelve adults with advanced-stage cancer and anxiety. In addition to monitoring safety and subjective experience before and during experimental treatment sessions, follow-up data including results from the Beck Depression Inventory, Profile of Mood States, and State-Trait Anxiety Inventory were collected unblinded for 6 months after treatment. Safe physiological and psychological responses were documented during treatment sessions. There were no clinically significant adverse events with psilocybin. The State-Trait Anxiety Inventory trait anxiety subscale demonstrated a significant reduction in anxiety at 1 and 3 months after treatment. The Beck Depression Inventory revealed an improvement of mood that reached significance at 6 months; the Profile of Mood States identified mood improvement after treatment with psilocybin that approached but did not reach significance. This study established the feasibility and safety of administering moderate doses of psilocybin to patients with advanced-stage cancer and anxiety. Some of the data revealed a positive trend toward improved mood and anxiety. These results support the need for more research in this long-neglected field. clinicaltrials.gov Identifier: NCT00302744.

    Two specific cognitive constructs that have been implicated in the development and maintenance of anxiety symptoms are anxiety sensitivity and emotional reasoning, both of which relate to the experience and meaning of physical symptoms of arousal or anxiety. The interpretation of physical symptoms has been particularly implicated in theories of social anxiety disorder, where internal physical symptoms are hypothesized to influence the individual's appraisals of the self as a social object. The current study compared 75 children on measures of anxiety sensitivity and emotional reasoning: 25 with social anxiety disorder, 25 with other anxiety disorders, and 25 nonanxious children (aged 7-12 years). Children with social anxiety disorder reported higher levels of anxiety sensitivity and were more likely than both other groups to view ambiguous situations as anxiety provoking, whether physical information was present or not. There were no group differences in the extent to which physical information altered children's interpretation of hypothetical scenarios. This study is the first to investigate emotional reasoning in clinically anxious children and therefore replication is needed. In addition, those in both anxious groups commonly had comorbid conditions and, consequently, specific conclusions about social anxiety disorder need to be treated with caution. The findings highlight cognitive characteristics that may be particularly pertinent in the context of social anxiety disorder in childhood and which may be potential targets for treatment. Furthermore, the findings suggest that strategies to modify these particular cognitive constructs may not be necessary in treatments of some other childhood anxiety disorders. © 2013 The Authors.

    2008-06-01

    Full Text Available The purpose of this paper is to present a fiberoptic vibration sensor based on the monitoring of the mode distribution in a multimode optical fiber. Detection of vibrations and their parameters is possible through observation of the output speckle pattern from the multimode optical fiber. A working experimental model has been built in which all used components are widely available and cheap: a CCD camera (a simple web-cam, a multimode laser in visible range as a light source, a length of multimode optical fiber, and a computer for signal processing. Measurements have shown good agreement with the actual frequency of vibrations, and promising results were achieved with the amplitude measurements although they require some adaptation of the experimental model. Proposed sensor is cheap and lightweight and therefore presents an interesting alternative for monitoring large smart structures.

    2017-12-01

    Multimodal communication involves the use of signals and cues across two or more sensory modalities. The genus Liolaemus (Iguania: Liolaemidae) offers a great potential for studies on the ecology and evolution of multimodal communication, including visual and chemical signals. In this study, we analyzed the response of male and female Liolaemus pacha to chemical, visual and combined (multimodal) stimuli. Using cue-isolation tests, we registered the number of tongue flicks and headbob displays from exposure to signals in each modality. Number of tongue flicks was greater when a chemical stimulus was presented alone than in the presence of visual or multimodal stimuli. In contrast, headbob displays were fewer in number with visual and chemical stimuli alone, but significantly higher in number when combined. Female signallers triggered significantly more tongue flicks than male signallers, suggesting that chemical cues are involved in sexual recognition. We did not find an inhibition between chemical and visual cues. On the contrary, we observed a dominance of the chemical modality, because when presented with visual stimuli, lizards also responded with more tongue flicks than headbob displays. The total response produced by multimodal stimuli was similar to that of the chemical stimuli alone, possibly suggesting non-redundancy. We discuss whether the visual component of a multimodal signal could attract attention at a distance, increasing the effectiveness of transmission and reception of the information in chemical cues.

    Although enhanced fear conditioning has been implicated in the origins of social anxiety disorder (SAD), laboratory evidence in support of this association is limited. Using a paradigm employing socially relevant unconditioned stimuli, we conducted two separate studies to asses fear conditioning in individuals with SAD and non-clinical individuals with high social anxiety (subclinical social anxiety [SSA]). They were compared with age-matched and gender-matched individuals with another anxiety disorder (panic disorder with agoraphobia) and healthy controls (Study 1) and with individuals with low social anxiety (Study 2). Contrary to our expectations, in both studies, self-report measures (ratings of anxiety, unpleasantness and arousal to the conditioned stimuli) of fear conditioning failed to discriminate between SAD or SSA and the other participant groups. Our results suggest that enhanced fear conditioning does not play a major role in pathological social anxiety. We used a social conditioning paradigm to study fear conditioning in clinical and subclinical social anxiety. We found no evidence of enhanced fear conditioning in social anxiety individuals. Enhanced fear conditioning may not be a hallmark of pathological social anxiety. Copyright © 2014 John Wiley & Sons, Ltd.

    This article reviewed the literature on public speaking anxiety in the context of social phobia subtyping. In total, 18 empirical studies on subtype issues related to public speaking anxiety were analyzed. Results of the reviewed studies are discussed in relation to their research method, that is, whether it focused on qualitative or quantitative aspects of subtype differences and whether it used a clinical or community sample. Evidence supported the premise that public speaking anxiety is a distinct subtype, qualitatively and quantitatively different from other subtypes of social phobia. The significance of this finding for social phobia studies using speech tasks to assess participants' state anxiety and behavioral performance is discussed.

    2003-12-01

    We propose a video genre classification method using multimodal features. The proposed method is applied for the preprocessing of automatic video summarization or the retrieval and classification of broadcasting video contents. Through a statistical analysis of low-level and middle-level audio-visual features in video, the proposed method can achieve good performance in classifying several broadcasting genres such as cartoon, drama, music video, news, and sports. In this paper, we adopt MPEG-7 audio-visual descriptors as multimodal features of video contents and evaluate the performance of the classification by feeding the features into a decision tree-based classifier which is trained by CART. The experimental results show that the proposed method can recognize several broadcasting video genres with a high accuracy and the classification performance with multimodal features is superior to the one with unimodal features in the genre classification.

    The Perinatal Anxiety Screening Scale (PASS; Somerville et al., 2014) reliably identifies perinatal women at risk of problematic anxiety when a clinical cut-off score of 26 is used. This study aimed to identify a severity continuum of anxiety symptoms with the PASS to enhance screening, treatment and research for perinatal anxiety. Antenatal and postnatal women (n=410) recruited from the antenatal clinics and mental health services at an obstetric hospital completed the Edinburgh Postnatal Depression Scale (EPDS), the Depression, Anxiety and Stress Scale (DASS-21), the Spielberg State-Trait Anxiety Inventory (STAI), the Beck Depression Inventory II (BDI), and the PASS. The women referred to mental health services were assessed to determine anxiety diagnoses via a diagnostic interview conducted by an experienced mental health professional from the Department of Psychological Medicine - King Edward Memorial Hospital. Three normative groups for the PASS, namely minimal anxiety, mild-moderate anxiety, and severe anxiety, were identified based on the severity of anxiety indicated on the standardised scales and anxiety diagnoses. Two cut-off points for the normative groups were calculated using the Jacobson-Truax method (Jacobson and Truax, 1991) resulting in three severity ranges: 'minimal anxiety'; 'mild-moderate anxiety'; and 'severe anxiety'. The most frequent diagnoses in the study sample were adjustment disorder, mixed anxiety and depression, generalised anxiety, and post-traumatic stress disorder. This may limit the generalisability of the severity range results to other anxiety diagnoses including obsessive compulsive disorder and specific phobia. Severity ranges for the PASS add value to having a clinically validated cut-off score in the detection and monitoring of problematic perinatal anxiety. The PASS can now be used to identify risk of an anxiety disorder and the severity ranges can indicate developing risk for early referrals for further assessments

    Living cells exhibit multi-mode transport that switches between an active, self-propelled motion and a seemingly passive, random motion. Cellular decision-making over transport mode switching is a stochastic process that depends on the dynamics of the intracellular chemical network regulating the cell migration process. Here, we propose a theory and an exactly solvable model of multi-mode active matter. Our exact model study shows that the reversible transition between a passive mode and an a...

  7. Dental anxiety and personality: investigating the relationship between dental anxiety and self-consciousness.

    Economou, George C

    2003-09-01

    This study investigated whether personality plays a role in a condition called dental anxiety. Specifically, the study examined the relationship between dental anxiety (the negative response to the stress elicited from a dental interaction) and self-consciousness (the tendency to evaluate aspects of oneself that are subject to private and public display). The purpose of this study was to identify the characteristics possessed by dentally anxious individuals who face potential health risks because of their avoidance. Sixty York University undergraduate students were recruited by convenience sampling to participate. These subjects completed Corah's Dental Anxiety Scale and the Self-Consciousness Scale. The Self-Consciousness Scale consists of three subscales, including private self-consciousness, public self-consciousness, and social anxiety. Results indicated an 0.54 significant correlation between dental anxiety and self-consciousness. The public self-consciousness and social anxiety subscales correlated the most with dental anxiety. Furthermore, the data did not indicate a significant moderating relationship for gender between the two aforementioned variables. These results contribute to the establishment of personality characteristics as one of the dimensions determining dental anxiety.

    Previous studies on autobiographical memory have focused on unimodal retrieval cues (i.e., cues pertaining to one modality). However, from an ecological perspective multimodal cues (i.e., cues pertaining to several modalities) are highly important to investigate. In the present study we investigated age distributions and experiential ratings of autobiographical memories retrieved with unimodal and multimodal cues. Sixty-two participants were randomized to one of four cue-conditions: visual, olfactory, auditory, or multimodal. The results showed that the peak of the distributions depends on the modality of the retrieval cue. The results indicated that multimodal retrieval seemed to be driven by visual and auditory information to a larger extent and to a lesser extent by olfactory information. Finally, no differences were observed in the number of retrieved memories or experiential ratings across the four cue-conditions.

    1983-01-01

    A number of nuclear multi-mode reactor power plants are conceptualized for use with solid core, fixed particle bed and rotating particle bed reactors. Multi-mode systems generate high peak electrical power in the open cycle mode, with MHD generator or turbogenerator converters and cryogenically stored coolants. Low level stationkeeping power and auxiliary reactor cooling (i.e., for the removal of reactor afterheat) are provided in a closed cycle mode. Depending on reactor design, heat transfer to the low power converters can be accomplished by heat pipes, liquid metal coolants or high pressure gas coolants. Candidate low power conversion cycles include Brayton turbogenerator, Rankine turbogenerator, thermoelectric and thermionic approaches. A methodology is suggested for estimating the system mass of multi-mode nuclear power plants as a function of peak electric power level and required mission run time. The masses of closed cycle nuclear and open cycle chemical power systems are briefly examined to identify the regime of superiority for nuclear multi-mode systems. Key research and technology issues for such power plants are also identified

    2011-03-01

    This review focuses on multimodal multiphoton tomography based on near infrared femtosecond lasers. Clinical multiphoton tomographs for 3D high-resolution in vivo imaging have been placed into the market several years ago. The second generation of this Prism-Award winning High-Tech skin imaging tool (MPTflex) was introduced in 2010. The same year, the world's first clinical CARS studies have been performed with a hybrid multimodal multiphoton tomograph. In particular, non-fluorescent lipids and water as well as mitochondrial fluorescent NAD(P)H, fluorescent elastin, keratin, and melanin as well as SHG-active collagen has been imaged with submicron resolution in patients suffering from psoriasis. Further multimodal approaches include the combination of multiphoton tomographs with low-resolution wide-field systems such as ultrasound, optoacoustical, OCT, and dermoscopy systems. Multiphoton tomographs are currently employed in Australia, Japan, the US, and in several European countries for early diagnosis of skin cancer, optimization of treatment strategies, and cosmetic research including long-term testing of sunscreen nanoparticles as well as anti-aging products.

    In this study, a unique set of antibody Fab fragments was designed in silico and produced to examine the relationship between protein surface properties and selectivity in multimodal chromatographic systems. We hypothesized that multimodal ligands containing both hydrophobic and charged moieties would interact strongly with protein surface regions where charged groups and hydrophobic patches were in close spatial proximity. Protein surface property characterization tools were employed to identify the potential multimodal ligand binding regions on the Fab fragment of a humanized antibody and to evaluate the impact of mutations on surface charge and hydrophobicity. Twenty Fab variants were generated by site-directed mutagenesis, recombinant expression, and affinity purification. Column gradient experiments were carried out with the Fab variants in multimodal, cation-exchange, and hydrophobic interaction chromatographic systems. The results clearly indicated that selectivity in the multimodal system was different from the other chromatographic modes examined. Column retention data for the reduced charge Fab variants identified a binding site comprising light chain CDR1 as the main electrostatic interaction site for the multimodal and cation-exchange ligands. Furthermore, the multimodal ligand binding was enhanced by additional hydrophobic contributions as evident from the results obtained with hydrophobic Fab variants. The use of in silico protein surface property analyses combined with molecular biology techniques, protein expression, and chromatographic evaluations represents a previously undescribed and powerful approach for investigating multimodal selectivity with complex biomolecules. © 2015 Wiley Periodicals, Inc.

    The Fundamental Nursing clinical practicum is an essential module for nursing students. Some feel stress or anxiety about attending this first placement; however, evidence demonstrates that it is rare to explore the feelings of anxiety felt by the nursing students concerning their first clinical practicum. This study was designed to explore student nurses' experiences of anxiety felt regarding their initial clinical practicum while studying for their University degree. A phenomenological approach was used. A university in Southern Taiwan. A purposive sampling of fifteen student nurses with anxiety reactions who had completed their first clinical practicum. Data were collected using a semi-structured guide and deep interview. Data were analyzed using Colaizzi's seven-step phenomenological method. Three themes surfaced in the findings. The first theme was anxiety around their first clinical practicum, which stirred up anxiety about: self-doubt, worry and fear; difficulty coping with the learning process; worry hampered establishing therapeutic relationships with patients; the progress of the patients' illness could not be predicted; and anxiety felt about lecturer-student interactions. The second theme was three phases of anxiety reactions, which included increasing anxiety before clinical practicum; exacerbated anxiety during clinical practicum, and relief of anxiety after clinical practicum. The third theme was coping behaviors. This comprised: self-reflection in preparation for clinical practicum; finding ways to release emotions; distractions from the anxiety; and, also facing their difficulties head-on. The findings could help raise the awareness of lecturers and students by understanding student nurses' anxiety experiences and facilitating a healthy preparation for their initial clinical practicum, consequently proactively helping reduce potential anxiety experiences.

    2014-01-01

    Highlights: • A plethora of pulmonary and systemic disorders, often associated with grave outcomes, may cause pulmonary infarction. • A stereotypical infarct is a peripheral wedge shaped pleurally based opacity but imaging findings can be highly variable. • Multimodality imaging is key to diagnosing the presence, aetiology and complications of pulmonary infarction. • Multimodality imaging of pulmonary infarction together with any ancillary features often guide to early targeted treatment. • CT remains the principal imaging modality with MRI increasingly used alongside nuclear medicine studies and ultrasound. - Abstract: The impact of absent pulmonary arterial and venous flow on the pulmonary parenchyma depends on a host of factors. These include location of the occlusive insult, the speed at which the occlusion develops and the ability of the normal dual arterial supply to compensate through increased bronchial arterial flow. Pulmonary infarction occurs when oxygenation is cut off secondary to sudden occlusion with lack of recruitment of the dual supply arterial system. Thromboembolic disease is the commonest cause of such an insult but a whole range of disease processes intrinsic and extrinsic to the pulmonary arterial and venous lumen may also result in infarcts. Recognition of the presence of infarction can be challenging as imaging manifestations often differ from the classically described wedge shaped defect and a number of weighty causes need consideration. This review highlights aetiologies and imaging appearances of pulmonary infarction, utilising cases to illustrate the essential role of a multimodality imaging approach in order to arrive at the appropriate diagnosis

    Background:Many studies have reported that depression and anxiety have bidirectional relationship with headache.However,few researches investigated the roles of depression or anxiety in patients with headache.We surveyed the prevalence of depression and anxiety as a complication or cause of headache among outpatients with a chief complaint of headache at neurology clinics in general hospitals.Additional risk factors for depression and anxiety were also analyzed.Methods:A cross-sectional study was conducted at 11 general neurological clinics.All consecutive patients with a chief complaint of headache were enrolled.Diagnoses of depression and anxiety were made using the Chinese version of the Mini International Neuropsychiatric Interview,and those for headache were made according to the International Classification of Headache Disorders,2nd Edition.The headache impact test and an 11-point verbal rating scale were applied to assess headache severity and intensity.Logistic regression was used to analyze risk factors of patients with headache for depression or anxiety.Results:A total of 749 outpatients with headache were included.Among them,148 (19.7%) were diagnosed with depression and 103 (13.7%) with anxiety.Further analysis showed that 114 (15.2%) patients complaining headache due to somatic symptoms of psychiatric disorders and 82 (10.9%) had a depression or anxiety comorbidity with headache.Most patients with depression or anxiety manifested mild to moderate headaches.Poor sleep and severe headache-related disabilities were predictors for either depression or anxiety.Conclusion:Clinicians must identify the etiology of headache and recognize the effects of depression or anxiety on headache to develop specific treatments.

  1. Context-Aware Multimodal FIDO Authenticator for Sustainable IT Services

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available Existing sustainable IT services have several problems related to user authentication such as the inefficiency of managing the system security, low security, and low usability. In this paper, we propose a Fast IDentity Online (FIDO authenticator that performs continuous authentication with implicit authentication based on user context and multimodal authentication. The proposed FIDO authenticator, a context-aware multimodal FIDO authentication (CAMFA method, combines information such as the user context, state of the mobile device, and user biometrics, then applies implicit and explicit authentication methods to meet the level of authentication required by the service provider. This reduces the user’s explicit authentication burden and continually authenticates users at risk during the session. Moreover, it is able to respond to attacks such as the theft of the authentication method or session hijacking. To study the effectiveness of CAMFA, we ran a user study by collecting data from 22 participants over 42 days of activity on a practical Android platform. The result of the user study demonstrates that the number of explicit authentication requests could be reduced by half. Based on the results of this study, an advanced user authentication that provides multimodal and continuous authentication could be applied to sustainable IT services.

    A dearth of laboratory tests to study actual human approach-avoidance behavior has complicated translational research on anxiety. The elevated plus-maze (EPM) is the gold standard to assess approach-avoidance behavior in rodents. Here, we translated the EPM to humans using mixed reality through a combination of virtual and real-world elements. In two validation studies, we observed participants' anxiety on a behavioral, physiological, and subjective level. Participants reported higher anxiety on open arms, avoided open arms, and showed an activation of endogenous stress systems. Participants' with high anxiety exhibited higher avoidance. Moreover, open arm avoidance was moderately predicted by participants' acrophobia and sensation seeking, with opposing influences. In a randomized, double blind, placebo controlled experiment, GABAergic stimulation decreased avoidance of open arms while alpha-2-adrenergic antagonism increased avoidance. These findings demonstrate cross-species validity of open arm avoidance as a translational measure of anxiety. We thus introduce the first ecologically valid assay to track actual human approach-avoidance behavior under laboratory conditions.

    A large field study of children in first and second grade explored how parents' anxiety about math relates to their children's math achievement. The goal of the study was to better understand why some students perform worse in math than others. We tested whether parents' math anxiety predicts their children's math achievement across the school year. We found that when parents are more math anxious, their children learn significantly less math over the school year and have more math anxiety by the school year's end-but only if math-anxious parents report providing frequent help with math homework. Notably, when parents reported helping with math homework less often, children's math achievement and attitudes were not related to parents' math anxiety. Parents' math anxiety did not predict children's reading achievement, which suggests that the effects of parents' math anxiety are specific to children's math achievement. These findings provide evidence of a mechanism for intergenerational transmission of low math achievement and high math anxiety. © The Author(s) 2015.

    The article presents the intervention model and primary outcomes of a preventive intervention designed to reduce anxiety symptoms and prevent the onset of anxiety disorders in the offspring of parents with anxiety disorders. Participants were 40 volunteer children (mean age = 8.94 years; 45% girls; 90% Caucasian) whose parents met criteria for a broad range of anxiety disorders. Families were randomly assigned to an 8-week cognitive-behavioral intervention, the Coping and Promoting Strength program (CAPS; n = 20) or a wait list control condition (WL; n = 20). Independent evaluators (IEs) conducted diagnostic interviews, and children and parents completed measures of anxiety symptoms. Assessments were conducted pre- and postintervention and 6 and 12 months after the postintervention assessment. On the basis of intent to treat analyses, 30% of the children in the WL group developed an anxiety disorder by the 1-year follow-up compared with 0% in the CAPS group. IE and parent-reported (but not child-reported) levels of anxiety showed significant decreases from the preintervention assessment to the 1-year follow-up assessment in the CAPS but not the WL group. Parental satisfaction with the intervention was high. Findings suggest that a family-based intervention may prevent the onset of anxiety disorders in the offspring of parents with anxiety disorders.

    Social network analysis (SNA) is becoming increasingly concerned not only with actors and their relations, but also with distinguishing between different types of such entities. For example, social scientists may want to investigate asymmetric relations in organizations with strict chains of command, or incorporate non-actors such as conferences and projects when analyzing coauthorship patterns. Multimodal social networks are those where actors and relations belong to different types, or modes, and multimodal social network analysis (mSNA) is accordingly SNA for such networks. In this paper, we present a design study that we conducted with several social scientist collaborators on how to support mSNA using visual analytics tools. Based on an openended, formative design process, we devised a visual representation called parallel node-link bands (PNLBs) that splits modes into separate bands and renders connections between adjacent ones, similar to the list view in Jigsaw. We then used the tool in a qualitative evaluation involving five social scientists whose feedback informed a second design phase that incorporated additional network metrics. Finally, we conducted a second qualitative evaluation with our social scientist collaborators that provided further insights on the utility of the PNLBs representation and the potential of visual analytics for mSNA.

    Full Text Available Guidelines recommend implementation of multimodal interventions to help prevent recurrent TIA/stroke. We undertook a systematic review to assess the effectiveness of behavioral secondary prevention interventions.Searches were conducted in 14 databases, including MEDLINE (1980-January 2014. We included randomized controlled trials (RCTs testing multimodal interventions against usual care/modified usual care. All review processes were conducted in accordance with Cochrane guidelines.Twenty-three papers reporting 20 RCTs (6,373 participants of a range of multimodal behavioral interventions were included. Methodological quality was generally low. Meta-analyses were possible for physiological, lifestyle, psychosocial and mortality/recurrence outcomes. Note: all reported confidence intervals are 95%. Systolic blood pressure was reduced by 4.21 mmHg (mean (-6.24 to -2.18, P = 0.01 I2 = 58%, 1,407 participants; diastolic blood pressure by 2.03 mmHg (mean (-3.19 to -0.87, P = 0.004, I2 = 52%, 1,407 participants. No significant changes were found for HDL, LDL, total cholesterol, fasting blood glucose, high sensitivity-CR, BMI, weight or waist:hip ratio, although there was a significant reduction in waist circumference (-6.69 cm, -11.44 to -1.93, P = 0.006, I2 = 0%, 96 participants. There was no significant difference in smoking continuance, or improved fruit and vegetable consumption. There was a significant difference in compliance with antithrombotic medication (OR 1.45, 1.21 to 1.75, P<0.0001, I2 = 0%, 2,792 participants and with statins (OR 2.53, 2.15 to 2.97, P< 0.00001, I2 = 0%, 2,636 participants; however, there was no significant difference in compliance with antihypertensives. There was a significant reduction in anxiety (-1.20, -1.77 to -0.63, P<0.0001, I2 = 85%, 143 participants. Although there was no significant difference in odds of death or recurrent TIA/stroke, there was a significant reduction in the odds of cardiac events (OR 0.38, 0

    To prospectively examine relations between maternal DSM-IV-TR anxiety and depressive disorders and excessive infant crying. Based on the prospective longitudinal Maternal Anxiety in Relation to Infant Development Study, n=306 expectant mothers were enrolled during early pregnancy and repeatedly interviewed until 16 months post partum. Lifetime and prospective information on maternal anxiety and depressive disorders was assessed via standardised diagnostic interviews (Composite International Diagnostic Interview for Women). Excessive crying (crying for ≥3 h per day on ≥3 days per week for ≥3 weeks) was assessed via Baby-DIPS. During the first 16 months after delivery, n=286 mother-infant dyads were available and included in the analyses. Excessive crying was reported by n=29 mothers (10.1%). Infants of mothers with anxiety disorders prior to pregnancy were at higher risk for excessive crying than infants of mothers without any anxiety disorder prior to pregnancy (OR=2.54, 95% CI 1.11 to 5.78, p=0.027). Risk was even increased when considering additionally incident anxiety disorders until delivery (OR=3.02, 95% CI 1.25 to 7.32, p=0.014) and until 16 months post partum (OR=2.87, 95% CI 1.13 to 7.28, p=0.027). Associations remained stable when adjusting for sociodemographic and perinatal covariates. Maternal depressive disorders prior to pregnancy were not significantly associated with excessive crying in this sample. Maternal lifetime and incident anxiety disorders revealed to be a robust predictor for excessive crying. Thus, early identification and monitoring of women with anxiety disorders is important to identify mother-infant dyads at risk for excessive crying. Published by the BMJ Publishing Group Limited.

    We provide a systematic, evidence-based medicine (EBM) review of the field of electrophysiology in the anxiety disorders. Presently, electrophysiological studies of anxiety focus primarily on etiological aspects of brain dysfunction. The review highlights many functional similarities across studies, but also identifies patterns that clearly differentiate disorder classifications. Such measures offer clinical utility as reliable and objective indicators of brain dysfunction in individuals and indicate potential as biomarkers for the improvement of diagnostic specificity and for informing treatment decisions and prognostic assessments. Common to most of the anxiety disorders is basal instability in cortical arousal, as reflected in measures of quantitative electroencephalography (qEEG). Resting electroencephalographic (EEG) measures tend to correlate with symptom sub-patterns and be exacerbated by condition-specific stimulation. Also common to most of the anxiety disorders are condition-specific difficulties with sensory gating and the allocation and deployment of attention. These are clearly evident from evoked potential (EP) and event-related potential (ERP) electrical measures of information processing in obsessive compulsive disorder (OCD), post-traumatic stress disorder (PTSD), panic disorder (PD), generalized anxiety disorder (GAD) and the phobias. Other'ERP measures clearly differentiate the disorders. However, there is considerable variation across studies, with inclusion and exclusion criteria, medication status and control group selection not standardized within condition or across studies. Study numbers generally preclude analysis for confound removal or for the derivation of diagnostic biomarker patterns at this time. The current trend towards development of databases of brain and cognitive function is likely to obviate these difficulties. In particular, electrophysiological measures of function are likely to play a significant role in the development and

    Inadequate physical activity has adverse health consequences among adolescents. Mental health problem can be developed by lack of physical activity however it is controversial. The current study aimed to examine the association between level of physical activity with depression, anxiety and stress symptoms among adolescents. A representative sample of 1747 adolescents (13-14 years) was randomly selected from 6 schools in a south part of Malaysia. Respondents were asked to fill consent form, and questionnaires including Depression Anxiety and Stress Scale-21 and Physical Activity Questionnaire for Adolescents. Majority of respondents (71.9%) was Malay and more than half of the adolescents had low physical activity. About 40% had depression symptoms, followed by anxiety symptoms (65.9%) and stress symptoms (38.5%). Level of physical activity was significantly associated with gender, anxiety and stress (P<0.001). There were no associations with race, religion and depression symptom. This study provides some evidence among school-going adolescents related to anxiety and stress symptoms and low physical activities. Further studies are needed to show the protection effects of higher physical activity for depression, anxiety and stress symptoms in adolescents.

    The aim was to identify risk indicators from preadolescence (age period 10-12) that significantly predict unfavorable deviations from normal anxiety development throughout adolescence (age period 10-17 years). Anxiety symptoms were assessed in a community sample of 2,220 boys and girls at three time-points across a 5-year interval. Risk indicators were measured at baseline and include indicators from the child, family, and peer domain. Associations with anxiety were measured with multilevel growth curve analyses. A stable difference in anxiety over adolescence was found between high and low levels of a range of child factors (frustration, effortful control), family factors (emotional warmth received from parents, lifetime parental internalizing problems), and peer factor (victims of bullying) (P competence, unfavorable parenting styles, and bully victims, decreased over adolescence (P parental education and family composition were not significant. Adjustment for concurrent depressive symptoms attenuated the associations, but those that were significant at P social phobia, panic, and obsessive-compulsive symptoms) was reported for each association. Several child, family, and peer factors measured in preadolescence were risk indicators of high levels of anxiety symptoms throughout adolescence. Some factors (such as rejective parenting) were vulnerability indicators for anxiety in early adolescence only, whereas other factors (such as peer victimization) were indicators of long-term elevated anxiety levels. © 2011 Wiley-Liss, Inc.

    Conditions in which speech therapy treatment is applied in autistic children are often not in accordance with characteristics of opinions and learning of people with autism. A systemic multimodal approach means motivating autistic people to develop their language speech skill through the procedure which allows reliving of their personal experience according to the contents that are presented in the their natural social environment. This research was aimed at evaluating the efficiency of speech treatment based on the systemic multimodal approach to the work with autistic children. The study sample consisted of 34 children, aged from 8 to 16 years, diagnosed to have different autistic disorders, whose results showed a moderate and severe clinical picture of autism on the Childhood Autism Rating Scale. The applied instruments for the evaluation of ability were the Childhood Autism Rating Scale and Ganzberg II test. The study subjects were divided into two groups according to the type of treatment: children who were covered by the continuing treatment and systemic multimodal approach in the treatment, and children who were covered by classical speech treatment. It is shown that the systemic multimodal approach in teaching autistic children affects the stimulation of communication, socialization, self-service and work as well as that the progress achieved in these areas of functioning was retainable after long time, too. By applying the systemic multimodal approach when dealing with autistic children and by comparing their achievements on tests applied before, during and after the application of this mode, it has been concluded that certain improvement has been achieved in the functionality within the diagnosed category. The results point to a possible direction in the creation of new methods, plans and programs in dealing with autistic children based on empirical and interactive learning.

    Radiotherapy is one of the major methods for treating cancer, but many patients undergoing radiotherapy have deep concerns about receiving radiation treatment. This problem is not generally appreciated and has not been adequately studied. The objective of this investigation was to empirically investigate the anxieties that cancer patients feel towards radiotherapy by using questionnaires to classify and quantitatively measure their concerns. A preliminary interview to develop a questionnaire was carried out with 48 patients receiving radiotherapy to discover their anxieties about on-going treatments. Subsequently, a main study was performed using a questionnaire with 185 patients to classify their types of anxiety and to ascertain the reliability and validity of the responses. Confirmatory factor analysis was then carried out with a 17-item Radiotherapy Categorical Anxiety Scale. Three anxiety factors were abstracted by factor analysis: adverse effects of radiotherapy, environment of radiotherapy, and treatment effects of radiotherapy. Reliability, content validity, and concurrent validity were obtained. The adequacy of the three-factor model of anxiety concerning radiotherapy was confirmed. A 17-item Radiotherapy Categorical Anxiety Scale was formulated to quantitatively measure the specific types of anxiety among cancer patients receiving radiotherapy. (author)

    Purpose: To quantify the anxiety associated with various assessment methods undertaken by post-graduate students and to contextualise this with other life experiences. Method: Spielberger's state and trait anxiety inventory was anonymously completed prior to the magnetic resonance imaging (MRI) and ultrasound (US) students undertaking assessments. The data were analysed as follows. The mean state and trait anxiety scores and standard deviations, associated with the assessment methods were calculated. An analysis of variance (ANOVA) was performed on the state and trait anxiety scores recorded. Post hoc tests (Sidak) were then performed and finally an analysis of covariance (ANCOVA) completed the analysis. Results: The seminar was the most anxiety provoking assessment method, followed by the objective structured clinical examination (OSCE) and the staged assessment, with the unseen written examination being the least anxiety provoking assessment. However, even the unseen written examination provoked more anxiety than elective surgery. There was a significant difference between the anxiety provoked by the aforementioned assessments only in the state anxiety scores, but not the trait anxiety scores (ANOVA). The significant differences were between both the OSCE and seminar and the unseen written examination, with the other differences not being significant as demonstrated by post hoc tests. ANCOVA, which controls for differences in the individual's trait score, also showed significant differences between the state anxiety scores between the OSCE and seminar and unseen written examinations. Conclusion: OSCEs and seminars are both significantly more anxiety provoking than unseen written examinations, but even unseen written examinations are more anxiety provoking than elective surgery. The anxiety provoking potential of assessments should not be underestimated.

    Until relatively recently the vast majority of imaging and electrophysiological studies of human brain activity have relied on single-modality measurements usually correlated with readily observable or experimentally modified behavioural or brain state patterns. Multi-modal imaging is the concept of bringing together observations or measurements from different instruments. We discuss the aims of multi-modal imaging and the ways in which it can be accomplished using representative applications. Given the importance of haemodynamic and electrophysiological signals in current multi-modal imaging applications, we also review some of the basic physiology relevant to understanding their relationship.

    2012-01-01

    We present a novel probabilistic framework that fuses information coming from the audio and video modality to perform speaker diarization. The proposed framework is a Dynamic Bayesian Network (DBN) that is an extension of a factorial Hidden Markov Model (fHMM) and models the people appearing in an audiovisual recording as multimodal entities that generate observations in the audio stream, the video stream, and the joint audiovisual space. The framework is very robust to different contexts, makes no assumptions about the location of the recording equipment, and does not require labeled training data as it acquires the model parameters using the Expectation Maximization (EM) algorithm. We apply the proposed model to two meeting videos and a news broadcast video, all of which come from publicly available data sets. The results acquired in speaker diarization are in favor of the proposed multimodal framework, which outperforms the single modality analysis results and improves over the state-of-the-art audio-based speaker diarization.

  5. Multi-modal locomotion: from animal to application

    Lock, R J; Burgess, S C; Vaidyanathan, R

    2014-01-01

    The majority of robotic vehicles that can be found today are bound to operations within a single media (i.e. land, air or water). This is very rarely the case when considering locomotive capabilities in natural systems. Utility for small robots often reflects the exact same problem domain as small animals, hence providing numerous avenues for biological inspiration. This paper begins to investigate the various modes of locomotion adopted by different genus groups in multiple media as an initial attempt to determine the compromise in ability adopted by the animals when achieving multi-modal locomotion. A review of current biologically inspired multi-modal robots is also presented. The primary aim of this research is to lay the foundation for a generation of vehicles capable of multi-modal locomotion, allowing ambulatory abilities in more than one media, surpassing current capabilities. By identifying and understanding when natural systems use specific locomotion mechanisms, when they opt for disparate mechanisms for each mode of locomotion rather than using a synergized singular mechanism, and how this affects their capability in each medium, similar combinations can be used as inspiration for future multi-modal biologically inspired robotic platforms.

    Full Text Available BACKGROUND Psychiatric disorders in pemphigus vulgaris may occur due to long term course, impact of body image, unlikelihood of complete recovery and frequent recurrences. These are the major predisposing factors towards depression and anxiety. Although, investigators have evaluated psychiatric aspects of the patients suffering from skin diseases, there are rare studies in India concerning mental health in pemphigus patients. Aim- The aim and objectives of the study is to estimate the prevalence of depression and anxiety in patients with pemphigus vulgaris, to assess the socio demographic profile and quality of life. MATERIALS AND METHODS Between august 2017 and September 2017, a cross sectional study of 105 patients diagnosed as pemphigus vulgaris attending pemphigus clinic of dermatology department, Rajiv Gandhi Government General Hospital, Chennai were assessed using semi structured proforma and following questionnaires GHQ-12, HAMA, HAMD, DLQI. RESULTS 105 patients were evaluated; 55% presented depression (58/120; 46 women and 12 men; 45 patients (43% with mild depression, 13 patients (12% with moderate depression. Duration of illness and social support presented statistical significance (P = 0.039 and (P <0.001 respectively. 32% presented anxiety (34/105; 25 women and 9 men; 32 patients (30% with mild anxiety, 2 patients (2% with moderate anxiety. Social support showed statistical significance (P<0.001. In DLQI, 32 patients had no effect, 24 patients (23% had small effect, 33 patients (31% had moderate effect, 16 patients (15% had very large effect. QOL was significantly impaired, particularly with poor social support (P<0.001, low education (P=0.010, duration of illness (P = 0.003 and number of episodes (P = 0.017. CONCLUSIONS Prevalence of depression and anxiety were higher in patients with pemphigus vulgaris and depression was found to be higher among females and anxiety was higher among male patients. Also increased duration of illness

    Strong evidence supports cognitive-behavioral therapy (CBT) for the treatment of childhood anxiety. Many studies suggest that parents play an etiological role in the development and maintenance of child anxiety. This pilot study examined the efficacy of a cognitive-behavioral intervention delivered to the parents of 31 anxious children (ages 7-13). Parents were randomly assigned to an individual parent-only CBT intervention (PCBT, n = 18) or wait-list control (WL, n = 13). PCBT demonstrated significant reductions in children's number of anxiety disorder diagnoses, parent-rated interference and clinician-rated severity of anxiety, and maternal protective behaviors at post-treatment, which were maintained at 3-months. WL did not demonstrate significant changes. There were no significant differences between conditions in child self-reported or parent-report of child anxiety symptoms. Findings were replicated in a combined sample of treated participants, as well as in an intent-to-treat sample. Parent-only CBT may be an effective treatment modality for child anxiety, though future research is warranted. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Anxiety disorders are prevalent in children with epilepsy. The purpose of this study was to evaluate the efficacy, adaptability, and feasibility of a manual-based, computer-assisted cognitive behavioral therapy (CBT) intervention for anxiety disorders in children with epilepsy. Fifteen anxious youth (aged 8-13 years) with epilepsy completed 12 weeks of manualized computer-assisted CBT. The children and parents completed a semi-structured interview at baseline, and questionnaires assessing symptoms of anxiety, depression, and behavior problems were completed prior to treatment, at treatment midpoint, after treatment completion, and at three months posttreatment. There were significant reductions in the symptoms of anxiety and depression reported by the children at completion of the intervention and at the three-month follow-up. Similarly, the parents reported fewer symptoms of anxiety and a reduction in behavior problems. No adverse events were reported. This CBT intervention for children with epilepsy and anxiety disorders appears to be safe, effective, and feasible and should be incorporated into future intervention studies.

    Hand hygiene (HH) is an essential component for preventing and controlling of healthcare-associated infection (HAI), whereas compliance with HH among health care workers (HCWs) is frequently poor. This study aimed to assess compliance and correctness with HH before and after the implementation of a multimodal HH improvement strategy launched by the World Health Organization (WHO). A quasi-experimental study design including questionnaire survey generalizing possible factors affecting HH behaviors of HCWs and direct observation method was used to evaluate the effectiveness of WHO multimodal HH strategy in a hospital of Traditional Chinese Medicine. Multimodal HH improvement strategy was drawn up according to the results of questionnaire survey. Compliance and correctness with HH among HCWs were compared before and after intervention. Also HH practices for different indications based on WHO "My Five Moments for Hand Hygiene" were recorded. In total, 553 HCWs participated in the questionnaire survey and multimodal HH improvement strategy was developed based on individual, environment and management levels. A total of 5044 observations in 23 wards were recorded in this investigation. The rate of compliance and correctness with HH improved from 66.27% and 47.75% at baseline to 80.53% and 88.35% after intervention. Doctors seemed to have better compliance with HH after intervention (84.04%) than nurses and other HCWs (81.07% and 69.42%, respectively). When stratified by indication, compliance with HH improved for all indications after intervention ( P  Implementing the WHO multimodal HH strategy can significantly improve HH compliance and correctness among HCWs.

    Although mental illness anxiety is described in the literature, there is very little information on which to draw when treating individuals who present with fears and worries about mental health. In fact, we identified no previous case descriptions focused on this form of anxiety and treated from a cognitive behavioral perspective. The current case study aims to advance the understanding of the clinical picture of mental illness anxiety, and facilitate the understanding of how cognitive behavioral techniques for health anxiety can be effectively adapted and implemented for such a case. A case study approach was adopted in which a baseline condition and repeated assessments were conducted during an 8-week treatment and 2-month follow-up period. In the current case study, we discuss the assessment, conceptualization, and cognitive behavioral treatment of a 24-year old woman who presented with mental illness anxiety. Several common health anxiety assessment tools and cognitive behavioural techniques were adapted for her particular clinical presentation. Consistent with research evidence for health anxiety, significant improvements in health anxiety and anxiety sensitivity were seen after eight sessions of therapy and maintained at 2-month follow-up. The results provide preliminary evidence that cognitive behavioral techniques for health anxiety can be effectively and efficiently adapted for mental illness anxiety. However, the lack of available research pertaining to mental illness anxiety contributes to challenges in conceptualization, assessment and treatment.

    Full Text Available Background: Panic disorder (PD is a highly prevalent and disabling mental health problem associated with different factors including perfectionism, stress, physiological anxiety, and anxiety sensitivity regarding physical concerns; however, no studies have analyzed the joint relationship between these factors and PD in a multi-factor model using structural equation modeling. Method: A cross-sectional study was carried out to collect data on these factors and self-reported DSM-IV past-year PD symptoms in a large sample of the general population (N=936. Results: Perceived stress had a significant effect in increasing physiological anxiety, which in turn had an important association with physical concerns. Perfectionism and perceived stress had an indirect relation with past year PD via the mediator role of physiological anxiety and physical concerns. Physical concerns, on one hand, seemed to mediate the impact between perfectionism and PD and, on the other, partially mediated the role between physiological anxiety and PD. Conclusions: Although there is considerable evidence on the association between each of these factors and PD, this model can be considered a broader and productive framework of research on the nature and treatment of PD.

    In a prospective, longitudinal, population-based study of 643 women participating in the Harvard Study of Moods and Cycles we examined whether psychosocial variables predicted a new or recurrent onset of an anxiety disorder. Presence of anxiety disorders was assessed every six months over three years via structured clinical interviews. Among individuals who had a new episode of anxiety, we confirmed previous findings that history of anxiety, increased anxiety sensitivity (the fear of anxiety related sensations), and increased neuroticism were significant predictors. We also found trend level support for assertiveness as a predictor of anxiety onset. However, of these variables, only history of anxiety and anxiety sensitivity provided unique prediction. We did not find evidence for negative life events as a predictor of onset of anxiety either alone or in interaction with other variables in a diathesis-stress model. These findings from a prospective longitudinal study are discussed in relation to the potential role of such predictors in primary or relapse prevention efforts. PMID:19699609

    2016-02-01

    Full Text Available Modern advances in neuroscience suggest learning occurs through three basic cognition patterns. Higher-level multimodal learning occurs when learning activities contain multiple cognition patterns. This case study details an application of these concepts where fine art, journaling, practicum experiences, and in-class processing were fused to create an active and participatory method of engaging social work students in critical thinking as related to differential impacts of clinical decision-making. The learning activities are described and multimodal learning is explained, along with the findings of a focus group used to assess student feedback. Student experiences and the potential adaptations of this approach are also addressed. The tentative findings of this case study indicate positive learning experiences and suggest a need for further research to explore the opportunities associated with the use of multimodal and art-infused learning techniques in social work courses.

    An accurate prediction of long term outcome after stroke is urgently required to provide early individualized neurorehabilitation. This study aimed to examine the added value of early neuroimaging measures and identify the best approaches for predicting motor outcome after stroke. This prospective study involved 34 first-ever ischemic stroke patients (time since stroke: 1-14 days) with upper limb impairment. All patients underwent baseline multimodal assessments that included clinical (age, motor impairment), neurophysiological (motor-evoked potentials, MEP) and neuroimaging (diffusion tensor imaging and motor task-based fMRI) measures, and also underwent reassessment 3 months after stroke. Bivariate analysis and multivariate linear regression models were used to predict the motor scores (Fugl-Meyer assessment, FMA) at 3 months post-stroke. With bivariate analysis, better motor outcome significantly correlated with (1) less initial motor impairment and disability, (2) less corticospinal tract injury, (3) the initial presence of MEPs, (4) stronger baseline motor fMRI activations. In multivariate analysis, incorporating neuroimaging data improved the predictive accuracy relative to only clinical and neurophysiological assessments. Baseline fMRI activation in SMA was an independent predictor of motor outcome after stroke. A multimodal model incorporating fMRI and clinical measures best predicted the motor outcome following stroke. fMRI measures obtained early after stroke provided independent prediction of long-term motor outcome.

  18. Diffusion Maps for Multimodal Registration

    Directory of Open Access Journals (Sweden)

    Gemma Piella

    2014-06-01

    Full Text Available Multimodal image registration is a difficult task, due to the significant intensity variations between the images. A common approach is to use sophisticated similarity measures, such as mutual information, that are robust to those intensity variations. However, these similarity measures are computationally expensive and, moreover, often fail to capture the geometry and the associated dynamics linked with the images. Another approach is the transformation of the images into a common space where modalities can be directly compared. Within this approach, we propose to register multimodal images by using diffusion maps to describe the geometric and spectral properties of the data. Through diffusion maps, the multimodal data is transformed into a new set of canonical coordinates that reflect its geometry uniformly across modalities, so that meaningful correspondences can be established between them. Images in this new representation can then be registered using a simple Euclidean distance as a similarity measure. Registration accuracy was evaluated on both real and simulated brain images with known ground-truth for both rigid and non-rigid registration. Results showed that the proposed approach achieved higher accuracy than the conventional approach using mutual information.

    Dedicated small-animal imaging devices, e.g. positron emission tomography (PET), computed tomography (CT) and magnetic resonance imaging (MRI) scanners, are being increasingly used for translational molecular imaging studies. The objective of this work was to determine the positional accuracy and precision with which tumors in situ can be reliably and reproducibly imaged on dedicated small-animal imaging equipment. We designed, fabricated and tested a custom rodent cradle with a stereotactic template to facilitate registration among image sets. To quantify tumor motion during our small-animal imaging protocols, 'gold standard' multi-modality point markers were inserted into tumor masses on the hind limbs of rats. Three types of imaging examination were then performed with the animals continuously anesthetized and immobilized: (i) consecutive microPET and MR images of tumor xenografts in which the animals remained in the same scanner for 2 h duration, (ii) multi-modality imaging studies in which the animals were transported between distant imaging devices and (iii) serial microPET scans in which the animals were repositioned in the same scanner for subsequent images. Our results showed that the animal tumor moved by less than 0.2-0.3 mm over a continuous 2 h microPET or MR imaging session. The process of transporting the animal between instruments introduced additional errors of ∼0.2 mm. In serial animal imaging studies, the positioning reproducibility within ∼0.8 mm could be obtained.

    The aim of the study was to evaluate the effects of a six-month physical training undertaken by haemodialysis (HD) patients, on the depression and anxiety. Patients with end stage renal disease (ESRD) were recruited from the dialysis station at the Department of Nephrology and Transplantation Medicine in Wroclaw. Physical training took place at the beginning of the first 4-hours of dialysis, three times a week for six months. A personal questionnaire, Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI) were used in the study. A total of 28 patients completed the study: 20 were randomised to endurance training and 8 were randomised to resistance training. Statistical analysis of depression and anxiety at the initial (t1) and final examination (t2) indicated a significant reduction in depression and anxiety, particularly anxiety as a trait (X2) in the whole study group. The change in anxiety as a state correlated with the disease duration, duration of dialysis and the initial level of anxiety as a state (t1X1). The change in anxiety as a trait significantly correlated with age and the initial level of anxiety (t1X2). Undertaking physical training during dialysis by patients with ESRD is beneficial in reducing their levels of anxiety and depression. Both resistance and endurance training improves mood, but only endurance training additionally results in anxiety reduction. © 2016 S. Karger AG, Basel.

    This study piloted the use of three relaxation interventions in an attempt to reduce levels of anxiety in patients who are immobilised for radiotherapy treatment of head and neck cancers, as well as trying to validate the study methodology. In addition to receiving normal radiation therapy treatment, 14 patients were assigned to either a control group not receiving the relaxation intervention or one of three validated relaxation intervention techniques; music therapy, aromatherapy or guided imagery. Patients in the intervention groups underwent the relaxation technique daily for the first seven days of treatment. On days 1, 3, 5 and 7 of treatment patients were required to complete the State Anxiety Inventory survey. While caution should be taken in accepting the results due to the small numbers of patients involved in the study and the non-randomised assignment of patients within the study, the results of the study demonstrate a clinically significant reduction in anxiety levels in each of the three relaxation interventions compared to the control group. The study demonstrated good study validity due to the ease of implementation, the unambiguous results generated, and the use of already validated anxiety intersections and measurement tools.

    We present a general model to account for the multimode nature of the quantum electromagnetic field in projective photon-counting measurements. We focus on photon-subtraction experiments, where non-Gaussian states are produced conditionally. These are useful states for continuous-variable quantum-information processing. We present a general method called mode reduction that reduces the multimode model to an effective two-mode problem. We apply this method to a multimode model describing broadband parametric down-conversion, thereby improving the analysis of existing experimental results. The main improvement is that spatial and frequency filters before the photon detector are taken into account explicitly. We find excellent agreement with previously published experimental results, using fewer free parameters than before, and discuss the implications of our analysis for the optimized production of states with negative Wigner functions.

  5. Sustained Spatial Attention in Touch: Modality-Specific and Multimodal Mechanisms

    2011-01-01

    Full Text Available Sustained attention to a body location results in enhanced processing of tactile stimuli presented at that location compared to another unattended location. In this paper, we review studies investigating the neural correlates of sustained spatial attention in touch. These studies consistently show that activity within modality-specific somatosensory areas (SI and SII is modulated by sustained tactile-spatial attention. Recent evidence suggests that these somatosensory areas may be recruited as part of a larger cortical network,also including higher-level multimodal regions involved in spatial selection across modalities. We discuss, in turn, the following multimodal effects in sustained tactile-spatial attention tasks. First, cross-modal attentional links between touch and vision, reflected in enhanced processing of task-irrelevant visual stimuli at tactuallyattended locations, are mediated by common (multimodal representations of external space. Second, vision of the body modulates activity underlying sustained tactile-spatial attention, facilitating attentional modulation of tactile processing in between-hand (when hands are sufficiently far apart and impairing attentional modulation in within-hand selection tasks. Finally, body posture influences mechanisms of sustained tactile-spatial attention, relying, at least partly, on remapping of tactile stimuli in external, visuallydefined, spatial coordinates. Taken together, the findings reviewed in this paper indicate that sustained spatial attention in touch is subserved by both modality-specific and multimodal mechanisms. The interplay between these mechanisms allows flexible and efficient spatial selection within and across sensory modalities.

    Full Text Available Math anxiety is a common phenomenon which can have a negative impact on numerical and arithmetic performance. However, so far little is known about the underlying neurocognitive mechanisms. This mini review provides an overview of studies investigating the neural correlates of math anxiety which provide several hints regarding its influence on math performance: while behavioral studies mostly observe an influence of math anxiety on difficult math tasks, neurophysiological studies show that processing efficiency is already affected in basic number processing. The purpose of this study is to provide some treatments to overcome students’ anxiety in math classroom at The University of Muhammadiyah Purwokerto, Indonesia especially in Math Department, but before it has attempted to investigate the factors that students’ anxiety can possibly stem from, both within the classroom environment and out of classroom in the wilder social context.

    This study describes the in silico design, surface property analyses, production and chromatographic evaluations of a diverse set of antibody Fab fragment variants. Based on previous findings, we hypothesized that the complementarity-determining regions (CDRs) constitute important binding sites for multimodal chromatographic ligands. Given that antibodies are highly diversified molecules and in particular the CDRs, we set out to examine the generality of this result. For this purpose, four different Fab fragments with different CDRs and/or framework regions of the variable domains were identified and related variants were designed in silico. The four Fab variant libraries were subsequently generated by site-directed mutagenesis and produced by recombinant expression and affinity purification to enable examination of their chromatographic retention behavior. The effects of geometric re-arrangement of the functional moieties on the multimodal resin ligands were also investigated with respect to Fab variant retention profiles by comparing two commercially available multimodal cation-exchange ligands, Capto MMC and Nuvia cPrime, and two novel multimodal ligand prototypes. Interestingly, the chromatographic data demonstrated distinct selectivity trends between the four Fab variant libraries. For three of the Fab libraries, the CDR regions appeared as major binding sites for all multimodal ligands. In contrast, the fourth Fab library displayed a distinctly different chromatographic behavior, where Nuvia cPrime and related multimodal ligand prototypes provided markedly improved selectivity over Capto MMC. Clearly, the results illustrate that the discriminating power of multimodal ligands differs between different Fab fragments. The results are promising indications that multimodal chromatography using the appropriate multimodal ligands can be employed in downstream bioprocessing for challenging selective separation of product related variants.

    The genetic and environmental origins of individual differences in scores on the anxiety-proneness scales from the Karolinska Scales of Personality were explored using a twin/adoption study design in a sample consisting of 15 monozygotic twin pairs reared apart, and 26 monozygotic and 29 dizygotic twin pairs reared together. The results showed that genetic factors accounted for individual differences in scores on the psychasthenia and somatic anxiety scales. The genetic determinants were not specific to each scale, but were common to both scales. Shared-rearing environmental determinants were important for individual differences in lack of assertiveness and psychic anxiety, and were common to both scales. Individual differences in muscular tension were found to be attributable to the effects of correlated environments. The most important factor explaining individual differences for all scales was the non-shared environment component. The evidence for an aetiologically heterogeneous anxiety-proneness construct emphasizes the appropriateness of a multi-dimensional approach to anxiety proneness.

    We sought to examine social anxiety as a risk factor for alcohol-related sexual victimization among college women. Women (Time 1: n = 574; Time 2: n = 88) who reported consuming alcohol at least once during the assessment timeframe participated. Social anxiety, alcohol use, alcohol-related consequences, and sexual victimization were assessed twice, approximately two months apart. Logistic regressions were used to examine social anxiety as a risk factor for alcohol-related sexual victimization at both time points. Longitudinally, women high in social anxiety were approximately three times more likely to endorse unwanted alcohol-related sexual experiences compared to women with low to moderate social anxiety. This study suggests social anxiety, a modifiable construct, increases risk for alcohol-related sexual victimization among college women. Implications for clinicians and risk-reduction program developers are discussed. Published by Elsevier Ltd.

  1. A Study on International Multimodal Transport Networks from Korea to Central Asia: Focus on Secondhand Vehicles

    Full Text Available Currently, high-income countries use multimodal transportation to export large quantities of secondhand vehicles to low-income countries. Secondhand vehicle export has shown its highest growth in recent years, especially in Korea. The problem of transporting secondhand vehicles from Korea to Central Asia is becoming an important issue, but few researchers are interested in it. The objective of this research is to determine the optimal transport network for exporting secondhand vehicles from Korea to Central Asian countries by combining experts’ opinions and real data from existing transport networks. The fuzzy Delphi method was applied to obtain factors to evaluate alternative multimodal transport networks for moving secondhand vehicles from Korea to Central Asian countries by judgment from experts. The analysis shows that among the five factors (total cost, total time, reliability, security, and transportation capability, total cost is the most considerable factor, followed by reliability, transportation capability, total time, and security. Additionally, in the mainly three multimodal transport networks, the sea+Trans-China Railway route is ranked first, followed by the sea+Trans-Siberian Railway and sea+truck routes.

    Preoperative anxiety in children is largely dependent on age and is influenced by anxiety level in parents. The current study compared the level of preoperative anxiety in preschool children versus school-aged children and its relationship with the state and trait anxiety of the parents. This study included 54 preschool children (2-5 years of age) and 48 school-age children (6-12 years) scheduled to receive ear, nose and throat, plastic or ophthalmologic surgeries. Preoperative anxiety of children was assessed in the holding area immediately prior to the surgery using a modified Yale Preoperative Anxiety Scale (m-YPAS). Compliance with anaesthesia induction was assessed using an Induction Compliance Checklist (ICC). The state and trait anxiety of the parent who accompanied the child was assessed using a State-Trait Anxiety Inventory (STAI) questionnaire. Both m-YPAS and ICC scores were higher in preschool children than in school-age children with significant correlation between the two measures. The STAI-S score of parents was higher in the preschool group than in the school-age group. No significant difference was found in STAI-T score between the two age groups. Children's m-YPAS score correlated with parental STAI-T score in both groups (rho = 0.297, P = 0.029 and rho = 0.338, P = 0.019, respectively) but only with STAI-S score in the preschool group (rho = 0.400, P = 0.003). Both preschool children and their parents are more anxious than school-age dyads prior to surgery. The anxiety level of the children correlates with state anxiety of the parents in preschool children but not in school-age children. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    In this work, the sensory creaminess of a set of four viscosity-matched fluid foods (single cream, evaporated milk, corn starch solution, and corn starch solution containing long chain free fatty acids) was tested by a panel of 16 assessors via controlled sensation mechanisms of smell only, taste only, taste and tactile, and integrated multimodal. It was found that all sensation channels were able to discriminate between creamy and non-creamy foods, but only the multimodal method gave creaminess ratings in agreement with the samples' fat content. Results from this study show that the presence of long chain free fatty acids has no influence on creaminess perception. It is certain that food creaminess is not a primary sensory property but an integrated sensory perception (or sensory experience) derived from combined sensations of visual, olfactory, gustatory, and tactile cues. Creamy colour, milky flavour, and smooth texture are probably the most important sensory features of food creaminess.

    There are few studies evaluating the association between practice of physical activity and mood in a population sample. This study evaluated the frequency of symptoms of depression and anxiety in the population of the city of Sao Paulo and their association with the report of practice of regular physical activity. This survey was conducted with the adult population of Sao Paulo between July and December of 2007. The sample was composed of 1042 volunteers (both genders) with a mean age of 41.9±14.4 years. The volunteers were evaluated using the Beck Depression Inventory, the Beck Anxiety Inventory, and two simple questions designed to evaluate and classify physical activity. Socioeconomic status was also determined according to Brazil's Economic Classification Criterion. People who do not engage in physical activity are two times more likely to exhibit symptoms of depression (PR: 2.1) and anxiety (PR: 2.5) compared with those who regularly practice physical activity and a higher prevalence of symptoms for anxiety (9.8%) and depression (10.9%) was observed among those claiming to not practice regular physical activity and 63.2% related did not practice any physical activity regularly. Altogether, these results suggest that people who do not practice physical activity have a higher chance of exhibiting symptoms of depression and anxiety when compared to those who perform physical activity regularly. In this sense, regular physical activity must be encouraged, and this incentive should be routine in both current and future public health policies. Although the methodology in the present study does not allow assigning a relation of cause and effect, we observed associations between symptoms of depression, anxiety and physical activity.

    Recognition of death anxiety experienced by patients who have survived violence and threats to life during war is of strong importance in delivery of best care for veterans experiencing health stressors. The aim of the study was to explore the death anxiety experience of veterans from the Iran-Iraq war. Using a phenomenological approach, 11 war veterans were interviewed related to death anxiety experiences. Four major themes included afterlife fears; alienated farewell; ambiguous separation; and physical dissolution. Patients who have been exposed to death trauma in the battlefield may carry added burden from unique cognitions and fears related to personal death.

  8. Teleportation of continuous variable multimode Greeberger-Horne-Zeilinger entangled states

    2008-01-01

    Quantum teleportation protocols of continuous variable (CV) Greeberger-Horne-Zeilinger (GHZ) and Einstein-Podolsky-Rosen (EPR) entangled states are proposed, and are generalized to teleportation of arbitrary multimode GHZ entangled states described by Van Loock and Braunstein (2000 Phys. Rev. Lett. 84 3482). Each mode of a multimode entangled state is teleported using a CV EPR entangled pair and classical communication. The analytical expression of fidelity for the multimode Gaussian states which evaluates the teleportation quality is presented. The analytical results show that the fidelity is a function of both the squeezing parameter r, which characterizes the multimode entangled state to be teleported, and the channel parameter p, which characterizes the EPR pairs shared by Alice and Bob. The fidelity increases with increasing p, but decreases with increasing r, i.e., it is more difficult to teleport the more perfect multimode entangled states. The entanglement degree of the teleported multimode entangled states increases with increasing both r and p. In addition, the fact is proved that our teleportation protocol of EPR entangled states using parallel EPR pairs as quantum channels is the best case of the protocol using four-mode entangled states (Adhikari et al 2008 Phys. Rev. A 77 012337).

    In the last decades, traffic noise has become a new challenge for efficient animal communication and several studies suggest that it is involved in population declines. Although poorly investigated in a traffic noise context, communication is generally multimodal, which can be viewed as a way to improve communication efficiency by allowing shift from a sensory modality to another when one modality suffers from noise. In the present study, we investigated multimodal shift in the European treefrog (Hyla arborea), a species using both acoustic and visual cues during male quality assessment task performed by females. Females were used in a discrimination task in two environmental conditions: with or without traffic noise. In traffic noise conditions, we showed that females' reliance on acoustic signal embedded in noise pollution did not decrease in favour of visual signals, therefore showing that females do not shift between modalities in response to traffic noise. Although, we did not evidence multimodal shift in our study, many species facing traffic noise present multimodal communication, and should be investigated to evaluate the importance of multimodal shift as a way to cope with traffic noise pollution.

    Thalassemic patients are vulnerable to emotional and behavioral problems. Each patient age group exhibits problems unique to that stage of development, and although up to 80 % of thalassemic patients are likely to have psychological disorders, e.g., anxiety and depression, predictors of these disorders remain poorly understood. The present study was designed to assess the prevalence of anxiety and depression in a sample of Egyptian thalassemic patients and to identify predictors of these psychiatric disorders. A case-control study was conducted in 218 thalassemic patients, with 244 healthy subjects as a control. All patients and control subjects were subjected to thorough evaluation of medical history and clinical examination, and examined by a psychiatrist using the clinician version of the structured clinical interview for DSM-IV (SCID-CV), hospital anxiety and depression scale and Coopersmith self-esteem inventory. Abnormal and borderline anxieties were reported by 36.7 and 20.6 % of thalassemic patients, respectively, while abnormal and borderline depressions were reported by 32.1 and 16.1 % of patients, respectively. Hospitalization, low self-esteem, diabetes mellitus and heart failure were independent predictors of anxiety. The independent predictors of depression were heart failure, hospitalization, diabetes mellitus, short stature and delayed puberty. Thalassemic patients were more vulnerable to anxiety and depression, indicating that screening and management for such psychiatric disorders should be considered in treating all such patients.

    Sleep disorders (SDs) are now recognized as a public health concern with considerable psychiatric and societal consequences specifically on the academic life of students. The aims of this study were to assess SDs in a group of university students in Lebanon and to examine the relationship between SDs and anxiety. An observational cross-sectional study was conducted at Saint-Joseph University, Lebanon, during the academic year 2013-2014. Four questionnaires were face-to-face administered to 462 students after obtaining their written consent: Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Generalized Anxiety Disorder 7-item scale (GAD-7). The prevalence of clinically significant insomnia was 10.6% (95% CI: 7.8-13.4%), more frequent in first year students. ISI mean score was 10.06 (SD = 3.76). 37.1% of the participants were poor sleepers. Excessive daytime sleepiness (EDS) and poor sleep were significantly more frequent among participants with clinical insomnia (p = 0.031 and 0.001 respectively). Clinically significant anxiety was more frequent in students suffering from clinical insomnia (p = 0.006) and in poor sleepers (p = 0.003). 50.8% of the participants with clinically significant anxiety presented EDS versus 30.9% of those with no clinically significant anxiety (panxiety reminds us of the importance of treating anxiety as soon as detected and not simply targeting the reduction of sleep problems.

    To investigate frequency, type, and characteristics of work anxieties in patients with somatic illness. Cross-sectional observation study. Neurology, orthopedic, and cardiology rehabilitation clinics. Patients (N=1610; age, 18-65y) with work anxieties. Not applicable. Patients who scored high on at least 2 of 9 items in the work-anxiety screening questionnaire and who reported impairment were investigated with a differential diagnostic interview on work anxieties and with the Mini-International Neuropsychiatric Interview on non-work-related common mental disorders. Patients also filled out a self-rating questionnaire on their subjective symptom load and sociodemographic data. Approximately 20% to 27% of the investigated inpatients in somatic rehabilitation (altogether n=393) received a work-anxiety diagnosis. Patients with orthopedic illness report highest work anxiety and have previous longest sick leave (20.6wk in the past 12mo). Patients with orthopedic illness suffer from work-related adjustment disorder with anxiety, social anxieties, and workplace phobias, whereas patients with cardiac illness are more often affected by hypochondriac anxieties. Anxieties of insufficiency and worrying occur equally in all indications. About a quarter of patients in somatic rehabilitation are in need of additional diagnostic attention owing to work anxieties. Differential diagnostic of work anxiety is needed for initiating adequate therapeutic action. Somatic rehabilitation physicians should be aware of work anxieties in their patients, especially in patients with orthopedic illness with previous long-term sick leave.

    2016-06-01

    Compressive sensing (CS) of sparse gigahertz-band RF signals using microwave photonics may achieve better performances with smaller size, weight, and power than electronic CS or conventional Nyquist rate sampling. The critical element in a CS system is the device that produces the CS measurement matrix (MM). We show that passive speckle patterns in multimode waveguides potentially provide excellent MMs for CS. We measure and calculate the MM for a multimode fiber and perform simulations using this MM in a CS system. We show that the speckle MM exhibits the sharp phase transition and coherence properties needed for CS and that these properties are similar to those of a sub-Gaussian MM with the same mean and standard deviation. We calculate the MM for a multimode planar waveguide and find dimensions of the planar guide that give a speckle MM with a performance similar to that of the multimode fiber. The CS simulations show that all measured and calculated speckle MMs exhibit a robust performance with equal amplitude signals that are sparse in time, in frequency, and in wavelets (Haar wavelet transform). The planar waveguide results indicate a path to a microwave photonic integrated circuit for measuring sparse gigahertz-band RF signals using CS.

    Empirical studies have consistently shown the effectiveness of a multicomponent CBT treatment of social anxiety disorder (SAD). Previous outcome studies on virtual reality and SAD have focused on people suffering from fear of public speaking and not full blown SAD. In this study, 45 adults receiving a DSM-IV-TR diagnostic of social anxiety were randomly assigned to traditional CBT treatment (with in vivo exposure), CBT-VR combined treatment, or a waiting list. Results show significant reduction of anxiety on all questionnaires as well as statistically significant interactions between both treatment groups and the waiting list.

    2017-05-01

    Full Text Available Objective: Anxiety is of particular importance following acquired brain injury (ABI, because anxiety has been identified as a significant predictor of functional outcomes. Continuity of self has been linked to post ABI adjustment and research has linked self-discrepancy to anxiety. This longitudinal study investigates the impact of affiliative and ‘self as doer’ self-categorisations anxiety.Materials and Methods: Data was collected at two time points. Fifty-three adult ABI survivors participating in post-acute community neuro-rehabilitation participated at time one and 32 of these participated at time two. Participants completed a 28-item identity questionnaire based on Leach et al.’s (2008 multicomponent model of ingroup identification which measured the strength of affiliative and self as doer identities. Anxiety was measured using the Hospital Anxiety and Depression Scale.Results: Analysis indicates a significant mediated relationship between affiliative identification and anxiety via self as doer identification. Contrary to initial prediction, this relationship was significant for those with consistency in affiliative self-categorisation and inconsistency in ‘self as doer’ self-categorisation.Conclusion: These findings can be interpreted as evidencing the importance of identity continuity and multiplicity following ABI and contribute to the understanding of these through the use of a social identity approach.

    2017-01-01

    This paper proposes a multimodal biometric scheme for human authentication based on fusion of voice and face recognition. For voice recognition, three categories of features (statistical coefficients, cepstral coefficients and voice timbre) are used and compared. The voice identification modality is carried out using Gaussian Mixture Model (GMM). For face recognition, three recognition methods (Eigenface, Linear Discriminate Analysis (LDA), and Gabor filter) are used and compared. The combination of voice and face biometrics systems into a single multimodal biometrics system is performed using features fusion and scores fusion. This study shows that the best results are obtained using all the features (cepstral coefficients, statistical coefficients and voice timbre features) for voice recognition, LDA face recognition method and scores fusion for the multimodal biometrics system

    It has been suggested that elevated maternal social anxiety may play a disorder-specific role in maintaining childhood social anxiety disorder (SAD), but few studies have examined whether mothers of children with SAD are more socially anxious than mothers of children with other anxiety disorders (ANX). This study set out to examine whether symptoms of social anxiety were more severe amongst mothers of 7-12 year old children presenting for treatment with SAD (n = 260) compared to those presenting with ANX (n = 138). In addition, we examined whether there were differences between these two groups in terms of maternal and paternal general anxiety, depression, and stress. Parents of 7-12 year old children referred for treatment of SAD or ANX completed self-report questionnaire measures of emotional symptoms. Compared to mothers of children with ANX, mothers of children with SAD reported significantly higher levels of social anxiety, general anxiety, and depression. In addition, fathers of children with SAD reported significantly higher levels of anxiety, stress, and depression than fathers of children with ANX. This study is one of the few existing studies that have examined mothers' and fathers' psychopathology across different childhood anxiety disorders. Compared to parents of children with ANX, parents of children with SAD may have poorer mental health which may inhibit optimum child treatment outcomes for children with SAD. Thus, targeting parental psychopathology may be particularly important in the treatment of childhood SAD. Consideration of parental psychopathology may be particularly important in the treatment of childhood social anxiety disorder. Mothers of children with social anxiety disorder are more socially anxious than mothers of children with other anxiety disorders Fathers of children with social anxiety disorder are more anxious and depressed than fathers of children with other anxiety disorders Participants were predominantly of high

    2017-08-01

    Full Text Available Despite its declining incidence, gastric cancer (GC remains a leading cause of cancer-related deaths worldwide. A multimodal approach to GC is critical to ensure optimal patient outcomes. Pretherapy fine resolution contrast-enhanced cross-sectional imaging, endoscopic ultrasound and staging laparoscopy play an important role in patients with newly diagnosed ostensibly operable GC to avoid unnecessary non-therapeutic laparotomies. Currently, margin negative gastrectomy and adequate lymphadenectomy performed at high volume hospitals remain the backbone of GC treatment. Importantly, adequate GC surgery should be integrated in the setting of a multimodal treatment approach.

    Multimodal analgesia is promoted as the best practice pain management for invasive animal research procedures. Universal acceptance and incorporation of multimodal analgesia requires assessing potential effects on study outcome. The focus of this study was to assess effects on embryo survival after multimodal analgesia comprising an opioid and nonsteroidal antiinflammatory drug (NSAID) compared with opioid-only analgesia during embryo transfer procedures in transgenic mouse production. Mice were assigned to receive either carprofen (5 mg/kg) with buprenorphine (0.1 mg/kg; CB) or vehicle with buprenorphine (0.1 mg/kg; VB) in a prospective, double-blinded placebo controlled clinical trial. Data were analyzed in surgical sets of 1 to 3 female mice receiving embryos chimeric for a shared targeted embryonic stem-cell clone and host blastocyst cells. A total of 99 surgical sets were analyzed, comprising 199 Crl:CD1 female mice and their 996 offspring. Neither yield (pups weaned per embryo implanted in the surgical set) nor birth rate (average number of pups weaned per dam in the set) differed significantly between the CB and VB conditions. Multimodal opioid–NSAID analgesia appears to have no significant positive or negative effect on the success of producing novel lines of transgenic mice by blastocyst transfer. PMID:21838973

    Asymptomatic high-risk subjects, randomized in the intervention arm of the ITALUNG trial (1,406 screened for lung cancer), were enrolled for the ITALUNG biomarker study (n = 1,356), in which samples of blood and sputum were analyzed for plasma DNA quantification (cut off 5 ng/ml), loss of heterozygosity and microsatellite instability. The ITALUNG biomarker panel (IBP) was considered positive if at least one of the two biomarkers included in the panel was positive. Subjects with and without lung cancer diagnosis at the end of the screening cycle with LDCT (n = 517) were evaluated. Out of 18 baseline screen detected lung cancer cases, 17 were IBP positive (94%). Repeat screen-detected lung cancer cases were 18 and 12 of them positive at baseline IBP test (66%). Interval cancer cases (2-years) and biomarker tests after a suspect Non Calcific Nodule follow-up were investigated. The single test versus multimodal screening measures of accuracy were compared in a simulation within the screened ITALUNG intervention arm, considering screen-detected and interval cancer cases. Sensitivity was 90% at baseline screening. Specificity was 71 and 61% for LDCT and IBP as baseline single test, and improved at 89% with multimodal, combined screening. The positive predictive value was 4.3% for LDCT at baseline and 10.6% for multimodal screening. Multimodal screening could improve the screening efficiency at baseline and strategies for future implementation are discussed. If IBP was used as primary screening test, the LDCT burden might decrease of about 60%. © 2017 UICC.

    Psychological adjustment following cancer occurrence remains a key issue among the survivors. This study aimed to investigate psychological distress in patients with breast cancer following completion of breast cancer treatments and to determine its associated factors. This was a prospective study of anxiety and depression in breast cancer patients. Anxiety and depression were measured using the Hospital Anxiety and Depression Scale at three points in time: baseline (pre-diagnosis), 3 months after initial treatment and 1 year after completion of treatment (in all 18 months follow-up). At baseline, the questionnaires were administered to all the suspected patients while both patients and the interviewer were blind to the final diagnosis. Socio-demographic and clinical data included age, education, marital status, disease stage and initial treatment. Repeated measure analysis was performed to compare anxiety and depression over the study period. Logistic regression analysis was performed to determine variables that predict anxiety and depression. Altogether 167 patients were diagnosed with breast cancer. The mean age of breast cancer patients was 47.2 (SD = 13.5) years, and the vast majority underwent mastectomy (82.6%). At 18 months follow-up, data for 99 patients were available. The results showed that anxiety and depression improved over the time (P < 0.001) although at 18-month follow-up, 38.4% and 22.2% of the patients presented with severe anxiety and depression, respectively. 'Fatigue' was found to be a risk factor for developing anxiety and depression at 3 months follow-up [odds ratio (OR) = 1.04, 95% Confidence interval (CI) = 1.01-1.07 and OR = 1.04, 95% CI = 1.02-1.07 respectively]. At 18 months follow-up, anxiety was predicted by 'pain' (OR = 1.02, 95% CI = 1.00-1.05), whereas depression was predicted by both 'fatigue' (OR = 1.06, 95% CI = 1.02-1.09) and 'pain' (OR = 1.05, 95% CI = 1.01-1.08).

    Full Text Available With the main objective of presenting a linguistic model for the analysis of identity construction in multimodal texts, particularly in advertising, this article attempts to integrate three theoretical frameworks, namely the types of discourse of the Socio-Discursive Interactionism, Greimas’ actantial roles and the symbolic processes of the Grammar of Visual Design proposed by Kress e van Leeuwen. The first two theories are used to analyze verbal language form whereas the third is exclusively for images in advertising. The data sample is a Thai bank pamphlet of Siam Commercial Bank, collected in Bangkok, Thailand, in June, 2015. According to the data analysis, the theoretical frameworks employed here proves that identity, the psychological product, exists in the human mind and can be indexed by language in interaction. Also, the analysis found that identity could be projected as multimodally as language manifestation, of which forms are not only verbal but also pictorial.

    This study aimed to evaluate the ultramorphological characteristics of tooth-resin interfaces and the bond strength (BS) of multimode adhesive systems to enamel and dentin. Multimode adhesives (Scotchbond Universal (SBU) and All-Bond Universal) were tested in both self-etch and etch-and-rinse modes and compared to control groups (Optibond FL and Clearfil SE Bond (CSB)). Adhesives were applied to human molars and composite blocks were incrementally built up. Teeth were sectioned to obtain specimens for microtensile BS and TEM analysis. Specimens were tested after storage for either 24 h or 1 year. SEM analyses were performed to classify the failure pattern of beam specimens after BS testing. Etching increased the enamel BS of multimode adhesives; however, BS decreased after storage for 1 year. No significant differences in dentin BS were noted between multimode and control in either evaluation period. Storage for 1 year only reduced the dentin BS for SBU in self-etch mode. TEM analysis identified hybridization and interaction zones in dentin and enamel for all adhesives. Silver impregnation was detected on dentin-resin interfaces after storage of specimens for 1 year only with the SBU and CSB. Storage for 1 year reduced enamel BS when adhesives are applied on etched surface; however, BS of multimode adhesives did not differ from those of the control group. In dentin, no significant difference was noted between the multimode and control group adhesives, regardless of etching mode. In general, multimode adhesives showed similar behavior when compared to traditional adhesive techniques. Multimode adhesives are one-step self-etching adhesives that can also be used after enamel/dentin phosphoric acid etching, but each product may work better in specific conditions.

    Summary Introduction There is evidence supporting an association between depression and anxiety in patients with chronic disease. Spasmodic dysphonia (SD) is a chronic, incurable, and disabling voice disorder. Reported rates of depression and anxiety in SD range from 7.1% to 72%, with a maximum number of 18 patients. The goal of this study was to define the coprevalence of depression and anxiety with SD. Materials and Methods A single-institution case-control study was performed from May to July 2010. Consecutive patients with SD and benign voice disorders were enrolled prospectively. On enrollment, patients were asked to fill out a questionnaire that reviewed the duration of the voice disorder and personal history of anxiety and depression, including current and lifetime diagnosis. Results One hundred forty-six controls with benign voice disorders and 128 patients with SD were enrolled. Patients with SD were no more likely to be diagnosed with depression or anxiety than those of the control group (odds ratio [OR] = 0.985, 95% confidence interval [CI] = 0.59–1.63; and OR = 1.314; 95% CI 0.75–2.3, respectively). Additionally, duration of disease was a risk factor for depression in both the SD group and the control group, and the association was not significantly different between groups. Conclusion Patients with SD were no more likely to have depression or anxiety than those with other voice disorders. It is important for otolaryngologists to be aware of the increased rates of depression in patients diagnosed with chronic diseases, including voice disorders, and to refer to a psychiatrist when appropriate.

    Taking the advantage of estimation of distribution algorithms (EDAs) in preserving high diversity, this paper proposes a multimodal EDA. Integrated with clustering strategies for crowding and speciation, two versions of this algorithm are developed, which operate at the niche level. Then these two algorithms are equipped with three distinctive techniques: 1) a dynamic cluster sizing strategy; 2) an alternative utilization of Gaussian and Cauchy distributions to generate offspring; and 3) an adaptive local search. The dynamic cluster sizing affords a potential balance between exploration and exploitation and reduces the sensitivity to the cluster size in the niching methods. Taking advantages of Gaussian and Cauchy distributions, we generate the offspring at the niche level through alternatively using these two distributions. Such utilization can also potentially offer a balance between exploration and exploitation. Further, solution accuracy is enhanced through a new local search scheme probabilistically conducted around seeds of niches with probabilities determined self-adaptively according to fitness values of these seeds. Extensive experiments conducted on 20 benchmark multimodal problems confirm that both algorithms can achieve competitive performance compared with several state-of-the-art multimodal algorithms, which is supported by nonparametric tests. Especially, the proposed algorithms are very promising for complex problems with many local optima.

    Full Text Available BACKGROUND: There is a well recognized association between depression and diabetes. However, there is little empirical data about the prevalence of depressive symptoms and anxiety among different groups of glucose metabolism in population based samples. The aim of this study was to determine whether the prevalence of increased levels of depression and anxiety is different between patients with type 2 diabetes and subjects with impaired glucose metabolism (IGM and normal glucose metabolism (NGM. METHODOLOGY/PRINCIPAL FINDINGS: Cross-sectional data from a population-based cohort study of 2667 residents, 1261 men and 1406 women aged 40-65 years from the Hoorn region, the Netherlands. Depressive symptoms and anxiety were measured using the Centre for Epidemiologic Studies Depression Scale (CES-D, score >or=16 and the Hospital Anxiety and Depression Scale--Anxiety Subscale (HADS-A, score >or=8, respectively. Glucose metabolism status was determined by oral glucose tolerance test. In the total study population the prevalence of depressive symptoms and anxiety for the NGM, IGM and type 2 diabetes were 12.5, 12.2 and 21.0% (P = 0.004 and 15.0, 15.3 and 19.9% (p = 0.216, respectively. In men, the prevalence of depressive symptoms was 7.7, 9.5 and 19.6% (p<0.001, and in women 16.4, 15.8 and 22.6 (p = 0.318, for participants with NGM, IGM and type 2 diabetes, respectively. Anxiety was not associated with glucose metabolism when stratified for sex. Intergroup differences (NGM vs. IGM and IGM vs. type 2 diabetes revealed that higher prevalences of depressive symptoms are mainly manifested in participants with type 2 diabetes, and not in participants with IGM. CONCLUSIONS: Depressive symptoms, but not anxiety are associated with glucose metabolism. This association is mainly determined by a higher prevalence of depressive symptoms in participants with type 2 diabetes and not in participants with IGM.

    Full Text Available Abstract Background Adult separation anxiety disorder (ASAD has been identified recently, but there is a paucity of data about its prevalence and associated characteristics amongst anxiety patients. This study assessed the prevalence and risk factor profile associated with ASAD in an anxiety clinic. Methods Clinical psychologists assigned 520 consecutive patients to DSM-IV adult anxiety subcategories using the SCID. We also measured demographic factors and reports of early separation anxiety (the Separation Anxiety Symptom Inventory and a retrospective diagnosis of childhood separation anxiety disorder. Other self-report measures included the Adult Separation Anxiety Symptom Questionnaire (ASA-27, the Depression, Anxiety, Stress Scales (DASS-21, personality traits measured by the NEO PI-R and the Work and Social Adjustment Scale. These measures were included in three models examining for overall differences and then by gender: Model 1 compared the conventional SCID anxiety subtypes (excluding PTSD and OCD because of insufficient numbers; Model 2 divided the sample into those with and without ASAD; Model 3 compared those with ASAD with the individual anxiety subtypes in the residual group. Results Patients with ASAD had elevated early separation anxiety scores but this association was unique in females only. Except for social phobia in relation to some comparisons, those with ASAD recorded more severe symptoms of depression, anxiety and stress, higher neuroticism scores, and greater levels of disability. Conclusions Patients with ASAD attending an anxiety clinic are highly symptomatic and disabled. The findings have implications for the classification, clinical identification and treatment of adult anxiety disorders.

    2017-01-01

    Full Text Available Mathematical anxiety is a phenomenon linked to poor attainment in mathematics and restricted development of mathematical skills among those who are afflicted by it. Unfortunately most undergraduate courses in business related areas require the further study of mathematics to enable effective business decision making and students who suffer from mathematical anxiety are placed at risk of underperformance or failure in such quantitative modules. This paper summarizes the results of a survey (n = 330 of students joining a university business school with a view to ascertaining the degree of mathematical anxiety exhibited by incoming students. Results of the survey show no significant differences in anxiety attributable to age or gender but significant differences attributable to level of study and subject area. Implications of the findings for a redesigned teaching approach are discussed drawing on suggestions from the literature surrounding mathematical anxiety.

    The objective of the Multi commodity Multimodal Network Project is the development of modeling tools and methodologies for the optimal sizing of production networks and multimodal distribution of multiple fuel and its incomes, considering investments and transportation costs. Given the inherently non-linear combinatory nature of the problem, the resolution of real instances by the complete model, in an exact way, becomes computationally intractable. Thus, the strategy for resolution should contain a combination of exacts and heuristics methods, that must be applied to subdivisions of the original problem. This paper deals with one of these subdivisions, tackling the problem of modeling a network of pipelines in order to drain the production of ethanol away from the producing plants. The objective consists in defining the best network topology, minimizing investment and operational costs, and attending the total demand. In order to do that, the network was considered a tree, where the nodes are the center of producing regions and the edges are the pipelines, trough where the ethanol produced by plants must be drained away. The main objective also includes the decision over the optimal diameter of each pipeline and the optimal size of the bombs, in order to minimize the pumping costs. (author)

The aims of this study were to assess SDs in a group of university students in Lebanon and to examine the relationship between SDs and anxiety.An observational cross-sectional study was conducted at Saint-Joseph University, Lebanon, during the academic year 2013-2014. Four questionnaires were face-to-face administered to 462 students after obtaining their written consent: Insomnia Severity Index (ISI, Pittsburgh Sleep Quality Index (PSQI, Epworth Sleepiness Scale (ESS, and Generalized Anxiety Disorder 7-item scale (GAD-7.The prevalence of clinically significant insomnia was 10.6% (95% CI: 7.8-13.4%, more frequent in first year students. ISI mean score was 10.06 (SD = 3.76. 37.1% of the participants were poor sleepers. Excessive daytime sleepiness (EDS and poor sleep were significantly more frequent among participants with clinical insomnia (p = 0.031 and 0.001 respectively. Clinically significant anxiety was more frequent in students suffering from clinical insomnia (p = 0.006 and in poor sleepers (p = 0.003. 50.8% of the participants with clinically significant anxiety presented EDS versus 30.9% of those with no clinically significant anxiety (p<0.0001.The magnitude of SDs in this sample of Lebanese university students demonstrate the importance of examining sleep health in this population. Moreover, the link between SD and anxiety reminds us of the importance of treating anxiety as soon as detected and not simply targeting the reduction of sleep problems.

    Insufficient sleep has been associated with impaired recognition of facial emotions. However, previous studies have found inconsistent results, potentially stemming from the type of static picture task used. We therefore examined whether insufficient sleep was associated with decreased emotion recognition ability in two separate studies using a dynamic multimodal task. Study 1 used a cross-sectional design consisting of 291 participants with questionnaire measures assessing sleep duration and self-reported sleep quality for the previous night. Study 2 used an experimental design involving 181 participants where individuals were quasi-randomized into either a sleep-deprivation (N = 90) or a sleep-control (N = 91) condition. All participants from both studies were tested on the same forced-choice multimodal test of emotion recognition to assess the accuracy of emotion categorization. Sleep duration, self-reported sleep quality (study 1), and sleep deprivation (study 2) did not predict overall emotion recognition accuracy or speed. Similarly, the responses to each of the twelve emotions tested showed no evidence of impaired recognition ability, apart from one positive association suggesting that greater self-reported sleep quality could predict more accurate recognition of disgust (study 1). The studies presented here involve considerably larger samples than previous studies and the results support the null hypotheses. Therefore, we suggest that the ability to accurately categorize the emotions of others is not associated with short-term sleep duration or sleep quality and is resilient to acute periods of insufficient sleep. © Sleep Research Society 2017.

    This study assesses the impact of screening for diabetes on anxiety levels in an ethnically mixed population in the UK, and explores whether beliefs about Type 2 diabetes account for these anxiety levels. This cross-sectional study recruited individuals who were identified at high risk of developing diabetes through general practitioners' (GPs) lists or through public media recruitment. Participants completed an oral glucose tolerance test (OGTT). Between blood tests, participants completed the Spielberger State Anxiety Scale Short Form, the Emotional Stability Scale of the Big Five Inventory 44 and three scales from the Diabetes Illness Representations Questionnaire, revised for this study. Of the 1339 who completed the OGTT and questionnaire booklet, 54% were female, with 21% from an Asian background. Forty-five per cent of participants reported little to moderate amounts of anxiety at screening (mean 35.2; sd = 11.6). There was no significant effect of family history of diabetes, ethnic group or recruitment method on anxiety. The only variable significantly associated (negatively) with anxiety was the personality trait of emotional stability. Of responders, 64% and 61% agreed that diabetes was caused by diet or hereditary factors, respectively. Only 155 individuals (12%) agreed that diabetes was serious, shortens life and causes complications. The results of this study replicate that of previous studies, indicating that screening for diabetes does not induce significant anxiety. Bivariate analysis indicated that individuals who perceived diabetes to be serious, life shortening and resulting in complications had higher anxiety scores, the personality trait of emotional stability being the strongest predictor of anxiety.

There are two combined methods A-MM and N-MM. The method A-MM models the whole network as a multimode component, and the method N-MM models each node as a multimode component. We prove that the maximum delay bound computed by the method A-MM is tighter than or equal to that computed by the method N-MM. Experiments show that our proposed methods can significantly decrease the analytical delay bound comparing with the separate flow analysis method. For the large-scale wireless sensor network with 32 thousands of sensor nodes, our proposed methods can decrease about 70% of the analytical delay bound.

    Multimodal nanoprobes have attracted intensive attentions since they can integrate various imaging modalities to obtain complementary merits of single modality. Meanwhile, recent interest in laser-induced photoacoustic imaging is rapidly growing due to its unique advantages in visualizing tissue structure and function with high spatial resolution and satisfactory imaging depth. In this review, we summarize multimodal nanoprobes involving photoacoustic imaging. In particular, we focus on the method to construct multimodal nanoprobes. We have divided the synthetic methods into two types. First, we call it "one for all" concept, which involves intrinsic properties of the element in a single particle. Second, "all in one" concept, which means integrating different functional blocks in one particle. Then, we simply introduce the applications of the multifunctional nanoprobes for in vivo imaging and imaging-guided tumor therapy. At last, we discuss the advantages and disadvantages of the present methods to construct the multimodal nanoprobes and share our viewpoints in this area.

    Multimodality imaging, specifically PET-CT, brought a new perspective into the fields of clinical imaging. Clinical cases have shown that PET-CT has great value in clinical diagnosis and experimental research. But PET-CT still bears some limitations. A major drawback is that CT provides only limited soft tissue contrast and exposes the patient to a significant radiation dose. MRI overcome these limitations, it has excellent soft tissue contrast, high temporal and spatial resolution and no radiation damage. Additionally, since MRI provides also functional information, PET-MRI will show a new direction of multimodality imaging in the future. (authors)

    Recent epidemiological data suggests 13.3% of Hong Kong residents suffered from Common Mental Disorders, most frequently mixed anxiety and depressive disorder. This study examines the weighted prevalence and associated risk factors of depression, anxiety and stress among Hong Kong nurses. A total of 850 nurses were invited to participate in this cross-sectional study. Participants completed the Depression, Anxiety and Stress Scale 21 and multiple logistic regression was used to determine significant relationships between variables. Chronic past-year illness and poor self-perceived mental health were significant correlates of past-week depression, anxiety and stress. It confirmed further positive correlations between depression and divorce, widowhood and separation, job dissatisfaction, disturbance with colleagues, low physical activity levels and sleep problems. Marital status; general medicine; sleep problems, and a lack of leisure significantly correlated with anxiety. Stress was significantly associated with younger age, clinical inexperience, past-year disturbance with colleagues, low physical activity, no leisure and drinking alcohol. Nurses were more depressed, anxious and stressed than the local general population, with over one-third of our respondents classified as subject to these disorders.

    Most of the research on intergroup anxiety has examined the impact of people's own anxiety on their own outcomes. In contrast, we show that in intergroup interactions, one's partner's anxiety is just as important as one's own anxiety (if not more important). Using a diary study among college roommates, we show that partners' anxiety predicts respondents' anxiety across time on a daily basis, as well as respondents' interest in living together again the next year. We discuss the importance of taking a relational approach to understanding intergroup interactions.

    Full Text Available Anxiety disorders constitute a sizeable worldwide health burden with profound social and economic consequences. The symptoms are wide-ranging; from hyperarousal to difficulties with concentrating. This latter effect falls under the broad category of altered cognitive performance; in this review we examine studies quantifying such impacts of anxiety on cognition. Specifically, we focus on the translational threat of unpredictable shock paradigm, a method previously used to characterize emotional responses and defensive mechanisms that is now emerging as valuable tool for examining the interaction between anxiety and cognition. In particular, we compare the impact of threat of shock on cognition in humans to that of pathological anxiety disorders. We highlight that both threat of shock and anxiety disorders promote mechanisms associated with harm avoidance across multiple levels of cognition (from perception to attention to learning and executive function – a ‘hot’ cognitive function which can be both adaptive and maladaptive depending upon the circumstances. This mechanism comes at a cost to other functions such as working memory, but leaves some functions, such as planning, unperturbed. We also highlight a number of cognitive effects that differ across anxiety disorders and threat of shock. These discrepant effects are largely seen in ‘cold’ cognitive functions involving control mechanisms and may reveal boundaries between adaptive (e.g. response to threat and maladaptive (e.g. pathological anxiety. We conclude by raising a number of unresolved questions regarding the role of anxiety in cognition that may provide fruitful avenues for future research.

    Full Text Available Abstract Background Anxiety disorders are highly prevalent in primary care and cause a substantial burden of disease. Screening on risk status, followed by preventive interventions in those at risk may prevent the onset of anxiety disorders, and thereby reduce the disease burden. The willingness to participate in screening and interventions is crucial for the scope of preventive strategies, but unknown. This feasibility study, therefore, investigated participation rates of screening and preventive services for anxiety disorders in primary care, and explored reasons to refrain from screening. Methods In three general practices, screening was offered to individuals visiting their general practitioner (total n = 2454. To assess risk status, a 10-item questionnaire was followed by a telephone interview (including the CIDI when scoring above a predefined threshold. Preventive services were offered to those at risk. Participation rates for screening and preventive services for anxiety disorders were assessed. Those not willing to be screened were asked for their main reason to refrain from screening. Results Of all individuals, 17.3% participated in initial screening, and of those with a possible risk status, 56.0% continued screening. In 30.1% of those assessed, a risk status to develop an anxiety disorder was verified. Of these, 22.6% already received some form of mental health treatment and 38.7% of them agreed to participate in a preventive intervention and were referred. The most frequently mentioned reasons to refrain from screening were the emotional burden associated with elevated risk status, the assumption not to be at risk, and a lack of motivation to act upon an elevated risk status by using preventive services. Conclusions Screening in general practice, followed by offering services to prevent anxiety disorders in those at risk did not appear to be a feasible strategy due to low participation rates. To enable the development of

    Social Anxiety Disorder (SAD) is a globally prevalent, chronic, debilitating psychiatric disorder affecting youth. With comorbidities including major depression, substance abuse, lower educational and work attainment, and increased suicide risk, it has a significant public health burden. The objective of this study was to estimate the prevalence of SAD in urban Indian undergraduate students and to study their Facebook (FB) usage patterns. In this exploratory cross-sectional study, 316 undergraduate students were screened for social anxiety using validated instruments, Social Interaction Anxiety Scale (SIAS) and Social Phobia Scale (SPS), and divided into two groups based on scores obtained. The groups were then compared with regards to behaviors and attitudes toward Facebook, obtained from a self-report questionnaire. SAD was estimated to be a significant, prevalent (7.8%) disorder in otherwise productive youth, and showed female preponderance. Higher specific social phobia scores were associated with the inability to reduce Facebook use, urges toward increasing use, spending more time thinking about Facebook, negative reactions to restricting use, and using it to forget one's problems. SAD was estimated to have a prevalence of 7.8% in our study, and was associated with stronger FB usage attitudes and patterns. We recommend that the relationship between social anxiety and Internet use be explored further, to study the possibility of Internet-based screening and intervention strategies having wider reach and appeal in socially anxious individuals.

    2012-12-01

    Full Text Available As new technologies continue to emerge, students and lecturers are provided with new educational tools. One such tool, which is increasingly used in higher education, is digital storytelling, i.e. multi-media digital narratives. Despite the increasing attention that education and media scholars have paid to digital storytelling, there is scant research examining digital narratives from a discourse-analytic perspective.This paper addresses this gap in the literature and, in line with the belief that individuals make meaning through a range of semiotic devices, including, among others, language, sound, graphics and text, it aims to examine discourse strategies of factuality and subjectivity in historical-cultural digital narratives and their multimodal realisations (Kress & Van Leeuwen 2001; Patrona 2005. To carry out this study a corpus of 16 digital stories was compiled and analysed from a multidisciplinary framework which draws from studies on digital storytelling, computer-mediated communication, media studies, and multimodal discourse analysis. Results show that students/digital story tellers resort to a number of varied multimodal discursive strategies which are constitutive of their identity as capable students in an educational setting.

    Anxiety disorders are characterised by long term worry, tension, nervousness, fidgeting and symptoms of autonomic system hyperactivity. Meditation is an age-old self regulatory strategy which is gaining more interest in mental health and psychiatry. Meditation can reduce arousal state and may ameliorate anxiety symptoms in various anxiety conditions. To investigate the effectiveness of meditation therapy in treating anxiety disorders Electronic databases searched include CCDANCTR-Studies and CCDANCTR-References, complementary and alternative medicine specific databases, Science Citation Index, Health Services/Technology Assessment Text database, and grey literature databases. Conference proceedings, book chapters and references were checked. Study authors and experts from religious/spiritual organisations were contacted. Types of studies: Randomised controlled trials. patients with a diagnosis of anxiety disorders, with or without another comorbid psychiatric condition. Types of interventions: concentrative meditation or mindfulness meditation. Comparison conditions: one or combination of 1) pharmacological therapy 2) other psychological treatment 3) other methods of meditation 4) no intervention or waiting list. Types of outcome: 1) improvement in clinical anxiety scale 2) improvement in anxiety level specified by triallists, or global improvement 3) acceptability of treatment, adverse effects 4) dropout. Data were independently extracted by two reviewers using a pre-designed data collection form. Any disagreements were discussed with a third reviewer, and the authors of the studies were contacted for further information. Two randomised controlled studies were eligible for inclusion in the review. Both studies were of moderate quality and used active control comparisons (another type of meditation, relaxation, biofeedback). Anti-anxiety drugs were used as standard treatment. The duration of trials ranged from 3 months (12 weeks) to 18 weeks. In one study

    Objective Most research on irritability and child psychopathology has focused on depressive disorders, bipolar disorder, and/or oppositional defiant disorder (ODD). Less is known about relationships between child anxiety and irritability and moderators of such associations. Method Structural equation modeling (SEM) examined associations between anxiety severity and irritability in a large sample of treatment-seeking youth with anxiety disorders (N=663, ages 7–19 years, M=12.25), after accounting for comorbid depressive disorders and ODD. Additional analyses examined whether associations were moderated by child gender, age, and generalized anxiety disorder (GAD) status. Results There was a direct link between child anxiety and irritability even after accounting for comorbid depressive disorders and ODD. Links between child anxiety and irritability were robust across child gender and age. Further, relationships between child anxiety and irritability were comparable across youth with and without GAD, suggesting that the anxiety–irritability link is relevant across child anxiety disorders and not circumscribed to youth with GAD. Conclusion Findings add to an increasing body of evidence linking child irritability to a range of internalizing and externalizing psychopathologies, and suggest that child anxiety assessment should systematically incorporate irritability evaluations. Further, youth in clinical settings displaying irritability should be assessed for the presence of anxiety. Moreover, treatments for childhood anxiety may do well to incorporate new treatment modules as needed that specifically target problems of irritability. PMID:26703910

    The aim of this study was to examine the prospective association between symptoms of anxiety and depression and risk of fracture in older people. Results showed that men, but not women, with probable anxiety at baseline had an increased risk of fracture. The use of psychotropic drugs has been linked with an increased risk of fracture in older people, but there are indications that the conditions for which these drugs were prescribed may themselves influence fracture risk. The aim of this study was to investigate the relation between symptoms of anxiety and depression and risk of fracture in older people. The study design is a prospective cohort study. One thousand eighty-seven men and 1,050 women aged 59-73 years completed the Hospital Anxiety and Depression Scale (HADS). Data on incident fracture during an average follow-up period of 5.6 years were collected through interview and a postal questionnaire. Compared to men with no or few symptoms of anxiety (score ≤7 on the HADS anxiety subscale), men with probable anxiety (score ≥11) had an increased risk of fracture: After adjustment for age and potential confounding factors, the odds ratio (OR) (95 % confidence interval) was 4.03 (1.55, 10.5). There were no associations between levels of anxiety and fracture risk in women. Few men or women had probable depression at baseline (score ≥11 on the HADS depression subscale). Amongst men with possible depression (score 8-10), there was an increased risk of fracture that was of borderline significance: multivariate-adjusted OR 3.57 (0.99, 12.9). There was no association between possible depression and fracture risk in women. High levels of anxiety in older men may increase their risk of fracture. Future research needs to replicate this finding in other populations and investigate the underlying mechanisms.

    This study aims to identify the relationship between students' learning styles and mathematics anxiety amongst Form Four students in Kerian, Perak. The study involves 175 Form Four students as respondents. The instrument which is used to assess the students' learning styles and mathematic anxiety is adapted from the Grasha's Learning Styles Inventory and the Mathematics Anxiety Scale (MAS) respectively. The types of learning styles used are independent, avoidant, collaborative, dependent, competitive and participant. The collected data is processed by SPSS (Statistical Packages for Social Sciences 16.0). The data is analysed by using descriptive statistics and inferential statistics that include t-test and Pearson correlation. The results show that majority of the students adopt collaborative learning style and the students have moderate level of mathematics anxiety. Moreover, it is found that there is significant difference between learning style avoidant, collaborative, dependent and participant based on gender. Amongst all students' learning style, there exists a weak but significant correlation between avoidant, independent and participant learning style and mathematics anxiety. It is very important for the teachers need to be concerned about the effects of learning styles on mathematics anxiety. Therefore, the teachers should understand mathematics anxiety and implement suitable learning strategies in order for the students to overcome their mathematics anxiety.

    Recent studies and anecdotal reports suggest that binaural auditory beats can affect mood, performance on vigilance tasks, and anxiety. To determine whether mildly anxious people would report decreased anxiety after listening daily for 1 month to tapes imbedded with tones that create binaural beats, and whether they would show a definite tape preference among 3 tapes. A 1-group pre-posttest pilot study. Patients' homes. A volunteer sample of 15 mildly anxious patients seen in the Clinique Psyché, Montreal, Quebec. Participants were asked to listen at least 5 times weekly for 4 weeks to 1 or more of 3 music tapes containing tones that produce binaural beats in the electroencephalogram delta/theta frequency range. Participants also were asked to record tape usage, tape preference, and anxiety ratings in a journal before and after listening to the tape or tapes. Anxiety ratings before and after tape listening, pre- and post-study State-Trait Anxiety Inventory scores, and tape preferences documented in daily journals. Listening to the binaural beat tapes resulted in a significant reduction in the anxiety score reported daily in patients' diaries. The number of times participants listened to the tapes in 4 weeks ranged from 10 to 17 (an average of 1.4 to 2.4 times per week) for approximately 30 minutes per session. End-of-study tape preferences indicated that slightly more participants preferred tape B, with its pronounced and extended patterns of binaural beats, over tapes A and C. Changes in pre- and posttest listening State-Trait Anxiety Inventory scores trended toward a reduction of anxiety, but these differences were not statistically significant. Listening to binaural beat tapes in the delta/theta electroencephalogram range may be beneficial in reducing mild anxiety. Future studies should account for music preference among participants and include age as a factor in outcomes, incentives to foster tape listening, and a physiologic measure of anxiety reduction. A

    2015-03-01

    Many technical innovations in multimodal radiologic imaging and bronchoscopy have emerged recently in the effort against lung cancer. Modern X-ray computed-tomography (CT) scanners provide three-dimensional (3D) high-resolution chest images, positron emission tomography (PET) scanners give complementary molecular imaging data, and new integrated PET/CT scanners combine the strengths of both modalities. State-of-the-art bronchoscopes permit minimally invasive tissue sampling, with vivid endobronchial video enabling navigation deep into the airway-tree periphery, while complementary endobronchial ultrasound (EBUS) reveals local views of anatomical structures outside the airways. In addition, image-guided intervention (IGI) systems have proven their utility for CT-based planning and guidance of bronchoscopy. Unfortunately, no IGI system exists that integrates all sources effectively through the complete lung-cancer staging work flow. This paper presents a prototype of a computer-based multimodal IGI system that strives to fill this need. The system combines a wide range of automatic and semi-automatic image-processing tools for multimodal data fusion and procedure planning. It also provides a flexible graphical user interface for follow-on guidance of bronchoscopy/EBUS. Human-study results demonstrate the system's potential.

    80 years ago, the PhD student Maria Goeppert predicted in her thesis in Goettingen, Germany, two-photon effects. It took 30 years to prove her theory, and another three decades to realize the first two-photon microscope. With the beginning of this millennium, first clinical multiphoton tomographs started operation in research institutions, hospitals, and in the cosmetic industry. The multiphoton tomograph MPTflexTM with its miniaturized flexible scan head became the Prism-Award 2010 winner in the category Life Sciences. Multiphoton tomographs with its superior submicron spatial resolution can be upgraded to 5D imaging tools by adding spectral time-correlated single photon counting units. Furthermore, multimodal hybrid tomographs provide chemical fingerprinting and fast wide-field imaging. The world's first clinical CARS studies have been performed with a hybrid multimodal multiphoton tomograph in spring 2010. In particular, nonfluorescent lipids and water as well as mitochondrial fluorescent NAD(P)H, fluorescent elastin, keratin, and melanin as well as SHG-active collagen have been imaged in patients with dermatological disorders. Further multimodal approaches include the combination of multiphoton tomographs with low-resolution imaging tools such as ultrasound, optoacoustic, OCT, and dermoscopy systems. Multiphoton tomographs are currently employed in Australia, Japan, the US, and in several European countries for early diagnosis of skin cancer (malignant melanoma), optimization of treatment strategies (wound healing, dermatitis), and cosmetic research including long-term biosafety tests of ZnO sunscreen nanoparticles and the measurement of the stimulated biosynthesis of collagen by anti-ageing products.

    The increasing application of digital techniques to diagnostic imaging is causing significant changes in several related activities, such as a reproduction of digital images on film. In the Department of Diagnostic Imaging of the University of Brescia, about 70% of the whole of images are produced by digital techniques; at present, most of these images are reproduced on film with a Multimodality System interfacing CT, MR, DSA, and DR units with a single laser printer. Our analysis evaluates the operative and economics aspects of image reproduction, by comparing the 'single cassette' multiformat Camera and the Laser Printer Multimodality SAystem. Our results point out the advantages obtained by reproducing images with a Laser Printer Multimodality System: outstanding quality, reproduction of multiple originals, and marked reduction in the time needed for both image archiving and film handling. The Laser Printer Multimodality System allows over 5 hours/day to be saved -that is to say the working day of an operator, who can be thus shifted to other functions. The important economic aspect of the reproduction of digital images on film proves the Laser Printer Multimodality System to have some advantage over Cameras

    A photonic lantern is studied which is formed by seven multimode fibers inserted into a pure silica capillary tube. The core of the tapered end has a uniform refractive index because the polymer claddings are removed before the fibers are inserted. Consequently, the light distribution is also uniform. Two theories describing a slowly varying waveguide and multimode coupling are used to analyze the photonic lantern. The transmission loss decreases as the length of the tapered part increases. For a device with a taper length of 3.4 cm, the loss is about 1.06 dB on average for light propagating through the taper from an inserted fiber to the tapered end and 0.99 dB in the reverse direction. For a device with a taper length of 0.7 cm, the two loss values are 2.63 dB and 2.53 dB, respectively. The results show that it is possible to achieve a uniform light distribution with the tapered end and a low-loss transmission in the device if parameters related to the lantern are reasonably defined.

    A photonic lantern is studied which is formed by seven multimode fibers inserted into a pure silica capillary tube. The core of the tapered end has a uniform refractive index because the polymer claddings are removed before the fibers are inserted. Consequently, the light distribution is also uniform. Two theories describing a slowly varying waveguide and multimode coupling are used to analyze the photonic lantern. The transmission loss decreases as the length of the tapered part increases. For a device with a taper length of 3.4 cm, the loss is about 1.06 dB on average for light propagating through the taper from an inserted fiber to the tapered end and 0.99 dB in the reverse direction. For a device with a taper length of 0.7 cm, the two loss values are 2.63 dB and 2.53 dB, respectively. The results show that it is possible to achieve a uniform light distribution with the tapered end and a low-loss transmission in the device if parameters related to the lantern are reasonably defined.

    To disentangle the complex associations of depression and anxiety with mild cognitive impairment (MCI) at the population level. We examined subgroups of anxiety symptoms and depression symptom profiles in relation to MCI, which we defined using both cognitive and functional approaches. We used an epidemiologic, cross-sectional study with an age-stratified, random, population-based sample of 1,982 individuals aged 65 years and over. Three definitions of MCI were used: 1) a purely cognitive classification into amnestic and nonamnestic MCI, 2) a combined cognitive-functional definition by International Working Group (IWG) criteria, and 3) a purely functional definition by the Clinical Dementia Rating (CDR) of 0.5. Three depression profiles were identified by factor analysis of the modified Center for Epidemiological Studies-Depression Scale: core mood, self-esteem/interpersonal, and apathy/neurovegetative profiles. Three anxiety groups, chronic mild worry, chronic severe anxiety, and recent-onset anxiety, were based on screening questions. Recent-onset anxiety was associated with MCI by nonamnestic and IWG criteria, chronic severe anxiety was associated with MCI by all definitions, and chronic mild worry was associated with none. Of the depression profiles, the core mood profile was associated with CDR-defined MCI, the apathy/neurovegetative profile was associated with MCI by amnestic, IWG, and CDR definitions, and the self-esteem/interpersonal profile was associated with none. In this population-based sample, subgroups with different anxiety and depression profiles had different relationships with cognitive and functional definitions of MCI. Anxiety, depression, and MCI are all multidimensional entities, interacting in complex ways that may shed light on underlying neural mechanisms.

    The present study aimed to investigate whether there is an association between type of living environment (urban versus rural) and anxiety, depression and psychosis in the Scottish population. Data were obtained from the Scottish Neighbourhood Statistics database on Scottish Index of Multiple Deprivation and urban-rural classifications for 6505 data zones across Scotland. Multiple regression was used to test the association between prescriptions for psychotropic medication for anxiety, depression and psychosis, and type of living environment according to urban-rural classification, controlling for a range of socio-economic factors. Urban-rural classification significantly predicted poorer mental health both before (β=-.29) and after (β=-.20) controlling for a large number of socio-economic variables, with more urban areas having higher rates of prescription for psychotropic medication for anxiety, depression and psychosis. The current study focussed on macro-level variables and did not include individual level data. As such, the study did not include data on individual diagnoses, but instead used drug prescriptions for anxiety, depression and psychosis as a proxy for level of affective disorders within data zones. More urban living environments in Scotland are associated with higher rates of prescription for psychotropic medication for anxiety, depression and psychosis. © 2013 Elsevier B.V.

    In this study we investigate the phenomenon of bruxism, defined as the act of clenching and/or grinding the teeth, a habit that compromises the orofacial region. It is often associated with emotional aspects, such as anxiety and stress, and may result in alterations to orofacial structures, functional modifications and social repercussions. The aim of this study was to determine a possible association between bruxism and anxiety underscoring the primary complaints related to masticatory function. Eighty volunteers participated in the study. They were divided into bruxers (N = 40) and non-bruxers (N = 40) of both sexes. The diagnosis of bruxism was made by clinical examination. The Trait-State Anxiety Inventory was used to assess anxiety levels and a questionnaire with structured questions related to daily activities, focusing on masticatory function (for the bruxism group), was applied to evaluate psychosocial aspects. The results of the study show a significant difference in state anxiety. Mean and standard deviation of state anxiety in the bruxism and non-bruxism groups was 42.7 +/- 9.6 and 38.6 +/- 8.2 (p bruxism, resulting in compromised masticatory function.

    Anxiety is a natural reaction to stress, but when excessive, it can develop into a debilitating disorder. Traditional treatments such as pharmaceuticals and psychotherapy have demonstrated efficacy in alleviating anxiety symptoms but are often costly and stigmatizing. This study tested whether a regimen of prescribed casual videogame (CVG) play could reduce individuals' anxiety symptom severity in a depressed population. CVGs are defined as fun, easy to play, spontaneous, and extremely popular. Data were taken from a larger study on depression and CVGs. Participants were screened for depression using a score of ≥5 (mild depression) on the Patient Health Questionnaire-9. After completing pre-intervention questionnaires, participants were randomized into the experimental (n=30) or control (n=29) group. Participants in the experimental group were prescribed a CVG of their choice to play three times per week, for 30 minutes, over a 1-month period. The State Trait Anxiety Inventory (STAI) was used to test the hypothesis. Repeated-measures analysis of variance revealed significant interaction of group by time for state and trait anxiety measures, supporting the hypothesis that anxiety severity would be different by group post-intervention. When state and trait anxiety measures were compared using within-subjects contrasts and between-group analyses, significant decreases in anxiety symptom severity were demonstrated. A prescribed regimen of CVG play significantly reduced state and trait anxiety symptom severity as measured by the STAI. Clinicians should consider using these easy-to-use and low-cost CVGs to address symptoms associated with state and trait anxiety.

    This cross-sectional study tested social anxiety symptoms, trait mindfulness, and drinking to cope with social anxiety as potential predictors and/or serial mediators of drinking problems. A community-based sample of individuals with co-occurring social anxiety symptoms and alcohol dependence were recruited. Participants ( N = 105) completed measures of social anxiety, drinking to cope with social anxiety, and alcohol use and problems. As well, participants completed the Five Facet Mindfulness Questionnaire , which assesses mindfulness facets of accepting without judgment, acting with awareness, not reacting to one's internal experiences, observing and attending to experiences, and labeling and describing. As predicted, the relationship between social anxiety symptoms and drinking problems was mediated by social anxiety coping motives across each of the models. Further, the relationship between specific mindfulness facets (acting with awareness, accepting without judgment, and describe) and drinking problems was serially mediated by social anxiety symptoms and drinking to cope with social anxiety. This research builds upon existing studies that have largely been conducted with college students to evaluate potential mediators driving drinking problems. Specifically, individuals who are less able to act with awareness, accept without judgment, and describe their internal experiences may experience heightened social anxiety and drinking to cope with that anxiety, which could ultimately result in greater alcohol-related problems.

    The study investigates the development of anxiety and depression during residents' postgraduate training as well as the symptom patterns and the prediction of these patterns of impaired affectivity by personality factors. It furthermore regards the differences between these patterns in workplace- and career-related factors as well as in worklife balance. In a prospective cohort study (2001-2007), 390 junior physicians of various specialties (54.9% females, 45.1% males) were investigated with respect to the percentage of participants with elevated anxiety and depression scores at the beginning of the second, fourth, and sixth year of residency, respectively. Symptom patterns were evaluated by two-step cluster analysis. The prediction of the assignment to the symptom patterns was investigated by logistic regression analysis. The differences in further factors between the two patterns was analyzed by t-tests. In the second year of residency, relevant anxiety symptoms were found in 30% of the physicians, and in the fourth and sixth year in 20%; relevant depression symptoms were found in 15% and 10%, respectively. The cluster analysis revealed two symptom patterns: Type A (n = 135, 34.6%) with continuously elevated anxiety and depression symptoms; and type B (n = 255, 65.4%) with continuously low values. Personality factors such as the sense of coherence, self-esteem, occupational self-efficacy expectation, and overcommitment significantly predicted the assignment to the symptom patterns. Also in terms of workload, mentoring experience, career satisfaction, and worklife balance, persons of type A differ from those of type B. Personality factors play an important role in physicians' ability to cope with job demands. Persons with an elevated vulnerability for anxiety and depression should be continuously supported and counselled by a mentor during residency.

    Objective: To evaluate the changes of brain function in patients with anxiety disorders. Methods: Regional cerebral perfusion was investigated using SPECT in 65 patients with anxiety disorders dragnosed according to the fourth edition of the diagnostic and statistical manual of mental disorder (DSMTD) criteria and in a matched control group of 21 healthy volunteers. 65 cases of the patients were further divided into: drug treated group (31 patients) and non-drug treated group (34 patients). The mean ages of the patients and the controls were (39.2±26.1) and (34.4±9.7) years, respectively. The severity of the anxiety was assessed using the 17-item Hamilton Anxiety scale (mean: 24.8±5.5 and 24.7±7.5, respectively). After administration of 740-925 MBq 99 Tc m -ethylene cysteinate direct (ECD) brain SPECT image study was performed. For the semi- quantitative analysis of the data, the ratios of the mean counts/pixel in the different cerebral regions of interest (ROI) to that of cerebellum were calculated respectively as a regional perfusion index (RPI). Some patients had a repeated SPECT after three months of treatment. Results: 93.8% (61/65) patients had relative hypoperfusions in some cerebral regions. Compared with the control group, the patients had a significant decrease of regional cerebral blood flow (rCBF) in the bilateral frontal lobes, paralimbic system, temporal lobes and basal ganglia. The course of disease had negatively correlated with the changes of rCBF in both groups of patients. Follow-up SPECT study demonstrated increased rCBF related with the symptomatic improvement. Conclusions: Patients with anxiety disorders had profound dysfunction of the frontal and temporal cortices, and was closely related to the symptom and therapy. 99 Tc m -ECD brain SPECT may offer the most accurate assessment of response to therapy. .

    The age-appropriate Sport Anxiety Scale-2 (SAS-2; Smith, Smoll, Cumming, & Grossbard, 2006) was used to assess levels of cognitive and somatic anxiety among male and female youth sport participants. Confirmatory factor analyses with a sample of 9-14 year old athletes (N=1038) supported the viability of a three-factor model of anxiety involving somatic anxiety, worry, and concentration disruption previously demonstrated in high school and college samples. Tests for factorial invariance revealed that the three-factor model was an equally good fit for 9-11 year olds and 12-14 year olds, and for both males and females. Gender and age were modestly related to anxiety scores. Worry about performing poorly was highest in girls and in older athletes, whereas boys reported higher levels of concentration disruption in competitive sport situations. Implications for emotional perception and for the study of competitive anxiety in young athletes are discussed.

    Despite the fact that numerous developmental models have highlighted the role of parental cognitive processes in connection with anxiety disorders in children and adolescents, the role of parents' beliefs about their children and parenting remains largely unexplored. This study investigated the specific association between parental beliefs and child separation anxiety. Parents of children with a diagnosis of Separation Anxiety Disorder (SAD) reported on beliefs and expectations related to their child's fears and own parenting competence. To study the potential specificity of relationships, a clinical control group of mothers of children with social phobia (SoP) and a group of mothers of children without a mental disorder (healthy controls, HC) were included. Results indicated that parents of anxious children had significantly higher levels of dysfunctional beliefs than the parents in the HC group. Mothers of children with SAD showed lower levels of parenting self-efficacy than mothers of children with SoP. They also demonstrated lower parenting self-efficacy and satisfaction compared to mothers of healthy children. Parental dysfunctional beliefs about child anxiety and paternal parenting self-efficacy were significantly positively associated with child anxiety. The effects remained significant after controlling for parental anxiety and depression. Due to the cross-sectional design of the study, causality of the found effects cannot be inferred. Data suggest that children's anxiety and parents' beliefs about their child's anxiety, coping skills and parenting are strongly associated. Further research is needed to investigate whether addressing parental cognitions in addition to parents' anxiety may improve prevention and intervention of child anxiety.

    The induction of anesthesia is one of the most stressful moments for a child who must undergo surgery: it is estimated that 60% of children suffer anxiety in the preoperative period. Preoperative anxiety is characterized by subjective feelings of tension, apprehension, nervousness, and worry. These reactions reflect the child's fear of separation from parents and home environment, as well as of loss of control, unfamiliar routines, surgical instruments, and hospital procedures. High levels of anxiety have been identified as predictors of postoperative troubles that can persist for 6 months after the procedure. Both behavioral and pharmacologic interventions are available to treat preoperative anxiety in children. The aim of this study was to investigate the effects of the presence of clowns on a child's preoperative anxiety during the induction of anesthesia and on the parent who accompanies him/her until he/she is asleep. The sample was composed of 40 subjects (5-12 years of age) who had to undergo minor day surgery and were assigned randomly to the clown group (N = 20), in which the children were accompanied in the preoperative room by the clowns and a parent, or the control group (N = 20), in which the children were accompanied by only 1 of his/her parents. The anxiety of the children in the preoperative period was measured through the Modified Yale Preoperative Anxiety Scale instrument (observational behavioral checklist to measure the state anxiety of young children), and the anxiety of the parents was measured with the State-Trait Anxiety Inventory (Y-1/Y-2) instrument (self-report anxiety behavioral instrument that measures trait/baseline and state/situational anxiety in adults). In addition, a questionnaire for health professionals was developed to obtain their opinion about the presence of clowns during the induction of anesthesia, and a self-evaluation form was developed to be filled out by the clowns themselves about their interactions with the child

    Embarrassment is emphasized, yet scantily described as a factor in extreme dental anxiety or phobia. Present study aimed to describe details of social aspects of anxiety in dental situations, especially focusing on embarrassment phenomena. Subjects (Ss) were consecutive specialist clinic patients, 16 men, 14 women, 20-65 yr, who avoided treatment mean 12.7 yr due to anxiety. Electronic patient records and transcribed initial assessment and exit interviews were analyzed using QSR"N4" software to aid in exploring contexts related to social aspects of dental anxiety and embarrassment phenomena. Qualitative findings were co-validated with tests of association between embarrassment intensity ratings, years of treatment avoidance, and mouth-hiding behavioral ratings. Embarrassment was a complaint in all but three cases. Chief complaints in the sample: 30% had fear of pain; 47% cited powerlessness in relation to dental social situations, some specific to embarrassment and 23% named co-morbid psychosocial dysfunction due to effects of sexual abuse, general anxiety, gagging, fainting or panic attacks. Intense embarrassment was manifested in both clinical and non-clinical situations due to poor dental status or perceived neglect, often (n = 9) with fear of negative social evaluation as chief complaint. These nine cases were qualitatively different from other cases with chief complaints of social powerlessness associated with conditioned distrust of dentists and their negative behaviors. The majority of embarrassed Ss to some degree inhibited smiling/laughing by hiding with lips, hands or changed head position. Secrecy, taboo-thinking, and mouth-hiding were associated with intense embarrassment. Especially after many years of avoidance, embarrassment phenomena lead to feelings of self-punishment, poor self-image/esteem and in some cases personality changes in a vicious circle of anxiety and avoidance. Embarrassment intensity ratings were positively correlated with years of

    Full Text Available Multimodal biometrics combine a variety of biological features to have a significant impact on identification performance, which is a newly developed trend in biometrics identification technology. This study proposes a novel multimodal biometrics recognition model based on the stacked extreme learning machines (ELMs and canonical correlation analysis (CCA methods. The model, which has a symmetric structure, is found to have high potential for multimodal biometrics. The model works as follows. First, it learns the hidden-layer representation of biological images using extreme learning machines layer by layer. Second, the canonical correlation analysis method is applied to map the representation to a feature space, which is used to reconstruct the multimodal image feature representation. Third, the reconstructed features are used as the input of a classifier for supervised training and output. To verify the validity and efficiency of the method, we adopt it for new hybrid datasets obtained from typical face image datasets and finger-vein image datasets. Our experimental results demonstrate that our model performs better than traditional methods.

    Lichen planus is a psychosomatic disease. Higher frequency of psychiatric symptoms, poor quality of life, higher level of anxiety and neuroendocrine and immune dysregulations, all these factors, will enhance the exacerbation of the disease. The present study was to assess depression, anxiety and stress levels in patients with oral lichen planus. The psychometric evaluation using the Depression Anxiety Stress Scale (DASS)-42 questionnaire was carried out, by the same investigator on all members of group 1 (Oral Lichen Planus) and group 2 (Control). DASS-42 questionnaire consists of 42 symptoms divided into three subscales of 14 items: Depression scale, anxiety scale, and stress scale. The Student t test was used to determine statistical difference for both the groups and to evaluate for significant relationships among variables. Psychological assessment using DASS-42 reveals lichen planus patients showed higher frequency of psychiatric co morbidities like depression, anxiety and stress compared to control group. This study has provided evidence that the DASS-42 questionnaire is internally consistent and valid measures of depression, anxiety, and stress. Psychiatric evaluation can be considered for patients with oral lichen planus with routine treatment protocols are recommended. DASS-42 Questionnaire can also be used to determine the level of anxiety, stress and depression in diseases of the oral mucosa like recurrent apthous stomatitis, burning mouth syndrome and TMD disorders.

    2015-01-01

    Music performance anxiety (MPA) regularly occurs when musicians present themselves before an audience in performance situations, and thus, it plays an important role in the careers of professional musicians. MPA is expressed on the emotional and physical level, as well as on the levels of thinking and behavior, and extends along a continuum of varying severity. Its performance-impairing, afflicting form is considered to be a specific type of social phobia, which requires therapy. There are different psychological theories, which contribute to the understanding of the phenomenon of MPA and provide basic principles for the various treatment approaches. Current "best practice," in our clinical experience, is a personal- and problem-oriented approach within a multimodal therapy model, including the range of psychoanalytic and cognitive behavioral therapies, body-oriented methods, and mental techniques. In order to avoid severe MPA, prevention in the field of music pedagogic is very important. Thus, the concepts of dealing positively with MPA should be implemented very early into the instrumental and vocal education of musicians. © 2015 Elsevier B.V. All rights reserved.

    2013-07-01

    Full Text Available Superparamagnetic iron oxide nanoparticles (SPION have emerged as an MRI contrast agent for tumor imaging due to their efficacy and safety. Their utility has been proven in clinical applications with a series of marketed SPION-based contrast agents. Extensive research has been performed to study various strategies that could improve SPION by tailoring the surface chemistry and by applying additional therapeutic functionality. Research into the dual-modal contrast uses of SPION has developed because these applications can save time and effort by reducing the number of imaging sessions. In addition to multimodal strategies, efforts have been made to develop multifunctional nanoparticles that carry both diagnostic and therapeutic cargos specifically for cancer. This review provides an overview of recent advances in multimodality imaging agents and focuses on iron oxide based nanoparticles and their theranostic applications for cancer. Furthermore, we discuss the physiochemical properties and compare different synthesis methods of SPION for the development of multimodal contrast agents.

    Recent epidemiological data suggests 13.3% of Hong Kong residents suffered from Common Mental Disorders, most frequently mixed anxiety and depressive disorder. This study examines the weighted prevalence and associated risk factors of depression, anxiety and stress among Hong Kong nurses. A total of 850 nurses were invited to participate in this cross-sectional study. Participants completed the Depression, Anxiety and Stress Scale 21 and multiple logistic regression was used to determine significant relationships between variables. Chronic past-year illness and poor self-perceived mental health were significant correlates of past-week depression, anxiety and stress. It confirmed further positive correlations between depression and divorce, widowhood and separation, job dissatisfaction, disturbance with colleagues, low physical activity levels and sleep problems. Marital status; general medicine; sleep problems, and a lack of leisure significantly correlated with anxiety. Stress was significantly associated with younger age, clinical inexperience, past-year disturbance with colleagues, low physical activity, no leisure and drinking alcohol. Nurses were more depressed, anxious and stressed than the local general population, with over one-third of our respondents classified as subject to these disorders. PMID:26371020

    Full Text Available Recent epidemiological data suggests 13.3% of Hong Kong residents suffered from Common Mental Disorders, most frequently mixed anxiety and depressive disorder. This study examines the weighted prevalence and associated risk factors of depression, anxiety and stress among Hong Kong nurses. A total of 850 nurses were invited to participate in this cross-sectional study. Participants completed the Depression, Anxiety and Stress Scale 21 and multiple logistic regression was used to determine significant relationships between variables. Chronic past-year illness and poor self-perceived mental health were significant correlates of past-week depression, anxiety and stress. It confirmed further positive correlations between depression and divorce, widowhood and separation, job dissatisfaction, disturbance with colleagues, low physical activity levels and sleep problems. Marital status; general medicine; sleep problems, and a lack of leisure significantly correlated with anxiety.

    Colonoscopy is generally tolerated, some patients regarding the procedure as unpleasant and painful and generally performed with the patient sedated and receiving analgesics. The effect of sedation and analgesia for colonoscopy is limited. Aromatherapy is also applied to gastrointestinal endoscopy to reduce procedural anxiety. There is lack of information about aromatherapy specific for colonoscopy. In this study, we aimed to performed a randomized controlled study to investigate the effect of aromatherapy on relieve anxiety, stress and physiological parameters of colonoscopy. A randomized controlled trail was carried out and collected in 2009 and 2010. The participants were randomized in two groups. Aromatherapy was then carried out by inhalation of Sunflower oil (control group) and Neroli oil (Experimental group). The anxiety index was evaluated by State Trait Anxiety Inventory-state (STAI-S) score before aromatherapy and after colonoscopy as well as the pain index for post-procedural by visual analogue scale (VAS). Physiological indicators, such as blood pressure (systolic and diastolic blood pressure), heart rate and respiratory rate were evaluated before and after aromatherapy. Participates in this study were 27 subjects, 13 in control group and 14 in Neroli group with average age 52.26 +/- 17.79 years. There was no significance of procedural anxiety by STAI-S score and procedural pain by VAS. The physiological parameters showed a significant lower pre- and post-procedural systolic blood pressure in Neroli group than control group. Aromatic care for colonoscopy, although with no significant effect on procedural anxiety, is an inexpensive, effective and safe pre-procedural technique that could decrease systolic blood pressure.

    Despite significant advances in targeted therapies for lung cancer, nearly all patients develop drug resistance within 6-12 months and prognosis remains poor. Developing drug resistance is a progressive process that involves tumor cells and their microenvironment. We hypothesize that microenvironment factors alter tumor growth and response to targeted therapy. We conducted in vitro studies in human EGFR-mutant lung carcinoma cells, and demonstrated that factors secreted from lung fibroblasts results in increased tumor cell survival during targeted therapy with EGFR inhibitor, gefitinib. We also demonstrated that increased environment stiffness results in increased tumor survival during gefitinib therapy. In order to test our hypothesis in vivo, we developed a multimodal optical imaging protocol for preclinical intravital imaging in mouse models to assess tumor and its microenvironment over time. We have successfully conducted multimodal imaging of dorsal skinfold chamber (DSC) window mice implanted with GFP-labeled human EGFR mutant lung carcinoma cells and visualized changes in tumor development and microenvironment facets over time. Multimodal imaging included structural OCT to assess tumor viability and necrosis, polarization-sensitive OCT to measure tissue birefringence for collagen/fibroblast detection, and Doppler OCT to assess tumor vasculature. Confocal imaging was also performed for high-resolution visualization of EGFR-mutant lung cancer cells labeled with GFP, and was coregistered with OCT. Our results demonstrated that stromal support and vascular growth are essential to tumor progression. Multimodal imaging is a useful tool to assess tumor and its microenvironment over time.

    Multi-modal interfaces can support the integration of humans with information processing systems and computational devices to maximize the unique qualities that comprise a complex system. In a dynamic environment, such as a nuclear power plant control room, multi-modal interfaces, if designed correctly, can provide complementary interaction between the human operator and the system which can improve overall performance while reducing human error. Developing such interfaces can be difficult for a designer without explicit knowledge of Human Factors Engineering principles. The Multi-modal Interface Design Advisor (MIDA) was developed as a support tool for system designers and developers. It provides design recommendations based upon a combination of Human Factors principles, a knowledge base of historical research, and current interface technologies. MIDA's primary objective is to optimize available multi-modal technologies within a human computer interface in order to balance operator workload with efficient operator performance. The purpose of this paper is to demonstrate MIDA and illustrate its value as a design evaluation tool within the nuclear power industry. (authors)

    Purpose: To our knowledge, no study has specifically assessed the time course of anxiety during radiotherapy (RT). The objective of this study was to assess anxiety time courses in patients with non-metastatic breast cancer. Material and methods: This multicenter, descriptive longitudinal study included 213 consecutive patients with breast cancer who completed visual analog scales (VASs) assessing state anxiety before and after the RT simulation and the first and last five RT sessions. Results: Pre- and post-session anxiety mean levels were highest at the RT simulation (respectively, 2.9 ± 2.9 and 1.6 ± 2.5) and first RT session (respectively, 3.4 ± 2.9 and 2.0 ± 2.4), then declined rapidly. Clinically relevant mean differences (⩾1 cm on the VAS) between pre- and post-simulation/session VAS scores were found only for the RT simulation (−1.3 ± 2.7; p < 0.001) and first RT session (−1.4 ± 2.4; p < 0.001). Five percent to 16% of patients presented clinically relevant anxiety (pre- and post-simulation/session VAS scores ⩾ 4 cm) throughout treatment. Conclusions: To optimize care, RT team members should offer all patients appropriate information about treatment at the simulation, check patients’ understanding, and identify patients with clinically relevant anxiety requiring appropriate support throughout RT

    The purpose of this study was to reveal the cross-sectional and longitudinal association of sleep with depression and anxiety among Chinese pregnant women. Pregnant women were recruited in Zhoushan Pregnant Women Cohort at Zhoushan Maternal and Child Care Hospital from 2011 to 2015. Self-rating depression scales (SDS) and self-rating anxiety scales (SAS) were used for evaluating depression and anxiety status at each trimester; corresponding sleep quality and duration were reported by pregnant women. Ordinary or multilevel linear and logistic regression model were used to estimate the cross-sectional or longitudinal association of sleep with depression and anxiety. The prevalence rates were 35.64, 24.23, and 26.24% for depression and 22.57, 17.41, and 21.04% for anxiety at 1st (T1), 2nd (T2), and 3rd trimester (T3), respectively. Controlling for potential confounders, it revealed significant cross-sectional and longitudinal associations of sleep with depression and anxiety status. In cross-sectional analysis, women who slept less than 8 h/day had higher risk of depression (T1: OR (95%CI) = 1.75 (1.39, 2.20); T2: 1.52 (1.26, 2.05); T3: 1.60 (1.18, 2.05)) and anxiety (T1: 2.00 (1.57, 2.55); T2: 1.86 (1.37, 2.54); T3: 1.33 (0.99, 1.79)). In the longitudinal analysis, multilevel model revealed that women with subjective "fair" or "bad" sleep quality had elevated risk of depression (OR ranging from 1.54 to 3.71) and anxiety (2.38 to 7.53) during pregnancy. Prenatal depression and anxiety status were prevalent in pregnant women. Sleep quality was associated with depression and anxiety status in both cross-sectional and longitudinal analyses, implying that improving sleep quality should benefit for mental health of pregnant women.

  2. High Current Anxiety Symptoms, But Not a Past Anxiety Disorder Diagnosis, are Associated with Impaired Fear Extinction

    Although impaired fear extinction has repeatedly been demonstrated in patients with anxiety disorders, little is known about whether these impairments persist after treatment. The current comparative exploratory study investigated fear extinction in 26 patients treated for their anxiety disorder in the years preceding the study as compared to 17 healthy control subjects. Fear-potentiated startle and subjective fear were measured in a cue and context fear conditioning paradigm within a virtual reality environment. Results indicated no differences in fear extinction between treated anxiety patients and control subjects. However, scores on the Beck Anxiety Inventory across all participants revealed impaired extinction of fear potentiated startle in subjects with high compared to low anxiety symptoms over the past week. Taken together, this exploratory study found no support for impaired fear extinction in treated anxiety patients, and implies that current anxiety symptoms rather than previous patient status determine the success of extinction.

    Pattern recognition is essential in chemical analysis of biological fluids. Reliable and sensitive methods for neurotransmitters analysis are needed. Therefore, we developed for pattern recognition of neurotransmitters: dopamine, epinephrine, norepinephrine a method based on multimode sensing. Multimode sensing was performed using microsensors based on diamond paste modified with 5,10,15,20-tetraphenyl-21H,23H-porphyrine, hemin and protoporphyrin IX in stochastic and differential pulse voltammetry modes. Optimized working conditions: phosphate buffer solution of pH 3.01 and KCl 0.1mol/L (as electrolyte support), were determined using cyclic voltammetry and used in all measurements. The lowest limits of quantification were: 10(-10)mol/L for dopamine and epinephrine, and 10(-11)mol/L for norepinephrine. The multimode microsensors were selective over ascorbic and uric acids and the method facilitated reliable assay of neurotransmitters in urine samples, and therefore, the pattern recognition showed high reliability (RSDneurotransmitters on biological fluids at a lower determination level than chromatographic methods. The sampling of the biological fluids referees only to the buffering (1:1, v/v) with a phosphate buffer pH 3.01, while for chromatographic methods the sampling is laborious. Accordingly with the statistic evaluation of the results at 99.00% confidence level, both modes can be used for pattern recognition and quantification of neurotransmitters with high reliability. The best multimode microsensor was the one based on diamond paste modified with protoporphyrin IX. Copyright © 2014 Elsevier B.V. All rights reserved.

    In this paper, we propose content-based video retrieval, which is a kind of retrieval by its semantical contents. Because video data is composed of multimodal information streams such as video, auditory and textual streams, we describe a strategy of using multimodal analysis for automatic parsing sports video. The paper first defines the basic structure of sports video database system, and then introduces a new approach that integrates visual stream analysis, speech recognition, speech signal processing and text extraction to realize video retrieval. The experimental results for TV sports video of football games indicate that the multimodal analysis is effective for video retrieval by quickly browsing tree-like video clips or inputting keywords within predefined domain.

    This study examined the impact of a selective anxiety prevention program for offspring of clinically anxious parents on three domains of child functioning: (1) social, (2) familial, and (3) emotional/behavioral. Dyads were randomized into either the Coping and Promoting Strength program (CAPS; n = 70) or Information Monitoring (IM; n = 66) comparison group. Multi-informant assessments were conducted at baseline, post intervention, and 6 and 12 months follow-ups. Random effects mixed models under the linear growth modeling (LGM) framework was used to assess the impact of CAPS on growth trajectories. Over time, children in the CAPS group had significantly lower anxiety, anxious/depressed symptoms, and lower total behavior problems (parent report), compared to children in IM group. The intervention did not impact other domains assessed (e.g., social functioning), which may be due to "floor effects" on these measures. Longitudinal follow-up data is needed to provide valuable information about this high risk population.

    Full Text Available Background: Mental health disorders affect around 500 million people worldwide. In India, around 10-12% of people are affected by a mental disorder either due to stress, depression, anxiety, or any other cause. Mental health of workers affects the productivity of the workplace, with estimates putting these losses to be over 100 million dollars annually. Aims: The study aims to measure depression, anxiety, and stress levels of workers in an industry and to investigate if it has any effect on productivity of the firm. Materials and Methods: The study utilized a cross-sectional design and was conducted among workmen of the firm. A sociodemographic based questionnaire and a mental health screening tool -Depression Anxiety Stress Scale (DASS-21 were used for the same. A total of 90 completed questionnaires were analyzed for the study. The data was analyzed for central tendencies as well as for any associations and correlations. Results: The study showed that none of the workers had a positive score for depression. It also showed that around 36% of the workers had a positive score for anxiety and 18% of the workers had a positive score for stress on DASS-21 scale. The odds ratio between stress and number of leaves taken by a worker in the last 3 months suggested a dose-response relationship, but was statistically insignificant. Conclusion: The study found a prevalence rate of around 18-36% for anxiety and stress amongst the workers at the factory. Large-scale studies will help understand the effect mental health status has on the Indian workplace.

    Poor regulation of emotions may involve impaired attention control. In the current paper, we report the results of two studies examining the interaction of anxiety, attention control, and cognitive load. In Study I, using a performance-based task to assess attention control, we examined whether anxiety is associated with impaired attention control, and whether these effects are influenced by working memory load. In Study II we examined these effects in patients with a diagnosis of Generalized Anxiety Disorder (GAD) compared to non-anxious control (NAC) participants. Results of Study I showed that high anxiety was associated with increased attention control, that is decreased interference from distractors, but only under high cognitive load. These results were replicated in Study II such that individuals with GAD showed increased attention control relative to NACs, but only under high cognitive load. These results help clarify previous predictions regarding the effect of anxiety on attention control. PMID:25355423

    Traditional biometric recognition systems rely on a single biometric signature for authentication. While the advantage of using multiple sources of information for establishing the identity has been widely recognized, computational models for multimodal biometrics recognition have only recently received attention. We propose a multimodal sparse representation method, which represents the test data by a sparse linear combination of training data, while constraining the observations from different modalities of the test subject to share their sparse representations. Thus, we simultaneously take into account correlations as well as coupling information among biometric modalities. A multimodal quality measure is also proposed to weigh each modality as it gets fused. Furthermore, we also kernelize the algorithm to handle nonlinearity in data. The optimization problem is solved using an efficient alternative direction method. Various experiments show that the proposed method compares favorably with competing fusion-based methods.

    Dental anxiety is common among children. Although there is a wealth of research investigating childhood dental anxiety, little consideration has been given to the child's perspective. This qualitative study sought to explore with children their own experiences of dental anxiety using a cognitive behavioural therapy assessment model. Face-to-face, semi-structured interviews were conducted with dentally anxious children aged 11-16 years. The Five Areas model was used to inform the topic guide and analysis. Data were analysed using a framework approach. In total, 13 children were interviewed. Participants described their experiences of dental anxiety across multiple dimensions (situational factors and altered thoughts, feelings, physical symptoms, and behaviours). Participants placed considerable value on communication by dental professionals, with poor communication having a negative influence on dental anxiety and the dentist-patient relationship. This study confirms the Five Areas model as an applicable theoretical model for the assessment of childhood dental anxiety. Children provided insights about their own dental anxiety experiences that have not previously been described. © 2016 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Assessing anxiety is an important part of the assessment of a child presenting for dental treatment; however, the use of dental anxiety scales in practice is not well-documented. To introduce child dental anxiety scales, and to monitor the extent to which dentists used them; to explore the experience and views of dentists regarding anxiety assessment. A mixed-methods design was employed. A protocol for child anxiety assessment was introduced to paediatric dentists in Eastman Dental Hospital. After 6 months, 100 patient files were audited to examine compliance with the protocol. Fourteen dentists were interviewed to explore their experience and views regarding anxiety assessment. Only five patients were assessed using the scales. Thematic analysis of the dentist interviews revealed three themes: 'Clinical observations and experience: The gold standard'; 'Scales as an estimate or adjunct'; and 'Shortcomings and barriers to using scales'. The dentists in our study did not use anxiety scales, instead they rely on their own experience/judgement. Therefore, scales should be recommended as an adjunct to judgement. Brief scales are recommended as clinicians lack time and expertise in administering anxiety questionnaires. Advantages of using scales and hands-on experience could be incorporated more in undergraduate training. © 2017 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    This paper presents a multimodality approach for the localization of epileptic foci using PET, MRI and EEG combined without the need of external markers. Mutual Information algorithm is used for MRI-PET registration. Dipole coordinates (provided by BESA software) are projected onto the MRI using a specifically developed algorithm. The four anatomical references used for electrode positioning (nasion, inion and two preauricular points) are located on the MRI using a triplanar viewer combined with a surface-rendering tool. Geometric transformation using deformation of the ideal sphere used for dipole calculations is then applied to match the patient's brain size and shape. Eight treatment-refractory epileptic patients have been studied. The combination of the anatomical information from the MRI, hipoperfusion areas in PET and dipole position and orientation helped the physician in the diagnosis of epileptic focus location. Neurosurgery was not indicated for patients where PET and dipole results were inconsistent; in two cases it was clinically indicated despite the mismatch, showing a negative follow up. The multimodality approach presented does not require external markers for dipole projection onto the MRI, this being the main difference with previous methods. The proposed method may play an important role in the indication of surgery for treatment- refractory epileptic patients.

    An atlas-based multimodal registration method for 2-dimension images with discrepancy structures was proposed in this paper. Atlas was utilized for complementing the discrepancy structure information in multimodal medical images. The scheme includes three steps: floating image to atlas registration, atlas to reference image registration, and field-based deformation. To evaluate the performance, a frame model, a brain model, and clinical images were employed in registration experiments. We measured the registration performance by the squared sum of intensity differences. Results indicate that this method is robust and performs better than the direct registration for multimodal images with discrepancy structures. We conclude that the proposed method is suitable for multimodal images with discrepancy structures. Graphical Abstract An Atlas-based multimodal registration method schematic diagram.

    Full Text Available Although impaired fear extinction has repeatedly been demonstrated in patients with anxiety disorders, little is known about whether these impairments persist after treatment. The current comparative exploratory study investigated fear extinction in 26 patients treated for their anxiety disorder in the years preceding the study as compared to 17 healthy control subjects. Fear-potentiated startle and subjective fear were measured in a cue and context fear conditioning paradigm within a virtual reality environment. Results indicated no differences in fear extinction between treated anxiety patients and control subjects. However, scores on the Beck Anxiety Inventory across all participants revealed impaired extinction of fear potentiated startle in subjects with high compared to low anxiety symptoms over the past week. Taken together, this exploratory study found no support for impaired fear extinction in treated anxiety patients, and implies that current anxiety symptoms rather than previous patient status determine the success of extinction.

    Recent research indicates that using multimodal learning experiences can be effective in teaching mathematics. Using a social semiotic lens within a participationist framework, this paper reports on a professional learning collaboration with a primary school teacher designed to explore the use of metaphors and modalities in mathematics instruction. This video case study was conducted in a year 2 classroom over two terms, with the focus on building children's understanding of computational strategies. The findings revealed that the teacher was able to successfully plan both multimodal and multiple metaphor learning experiences that acted as semiotic resources to support the children's understanding of abstract mathematics. The study also led to implications for teaching when using multiple metaphors and multimodalities.

    Test anxiety aggravates psychological distress and reduces the motivation among graduate students. This study aimed to identify psychological intervention for test anxiety, which reduces the level of psychological distress, amotivation and increases the intrinsic and extrinsic motivation among medical students. Westside test anxiety scale, Kessler Perceived Stress Scale and Academic Motivation Scale were used to measure test anxiety, psychological distress and motivation on 436 1(st) year medical students. Out of 436 students, 74 students who exhibited moderate to high test anxiety were randomly divided into either experimental or waiting list group. In this true randomized experimental study, 32 participants from the intervention group received five sessions of psychological intervention consist of psychoeducation, relaxation therapy and systematic desensitization. Thirty-three students from waiting list received one session of advice and suggestions. After received psychological intervention participants from the intervention group experienced less anxiety, psychological distress, and amotivation (P < 0.01) and high intrinsic and extrinsic motivation (P < 0.01) in the postassessment compared with their preassessment scores. Overall psychological intervention is effective to reduce anxiety scores and its related variables.

    Thousands of Nepalese women were widowed as a consequence of a decade (1996-2006) long civil war in Nepal. These women are at grave risk of mental health problems due to both traumatic experiences and violation of natural order of widowhood. The present study explores the depression and anxiety among war-widows. In 2012, a cross-sectional study was designed to interview 358 war-widows using validitated Beck Depression Inventory and Beck Anxiety Inventory in four districts of Nepal - Bardiya, Surkhet, Sindhupalchowk and Kavrepalanchowk with history of high conflict intensity. The prevalence of depression and anxiety was 53% and 63% respectively. Financial stress was significantly associated with depression (2.67, 95% CI: 1.40-5.07) and anxiety (2.37, 95% CI: 1.19-4.72). High autonomy of women as compared to low autonomy, high social support as compared to low social support and literacy as opposed to illiteracy was associated with less likelihood of depression and anxiety. Our results suggest high magnitude of depression and anxiety among war-widows in Nepal. Future policy efforts should be directed at providing mental health services to identify mental health issues among conflict affected individuals with focus on education, employment and activities to promote social support and autonomy at community.

    Previous studies indicated that parenting styles were important influencing factors for the development of children's well-being. It is known that mass migration to the cities in China will affect family relations. However, few studies focused on the relationship between parenting styles and adolescents' mental health in migrant families. Thus, this study aimed to investigate how parenting styles could affect adolescent's social anxiety in migrant families. A total number of 1,345 adolescents in migrant families from four non-government-funded junior middle schools in Guangdong province formed the research sample. Parenting styles were measured using short-form of the Egna Minnen Beträffande Uppfostran, and social anxiety was evaluated using Social Anxiety Subscale of Self-Consciousness Scale. The results showed that emotional warmth, overprotection and rejection were significantly more often perceived from mothers than from fathers. Significant group differences between high social anxiety group and low social anxiety group were found in both father's rearing styles and mother's rearing styles. Furthermore, in migrant families, paternal emotional warmth could decrease adolescents' social anxiety, whereas maternal overprotection could increase it.

    Full Text Available Context: Lichen planus is a psychosomatic disease. Higher frequency of psychiatric symptoms, poor quality of life, higher level of anxiety and neuroendocrine and immune dysregulations, all these factors, will enhance the exacerbation of the disease. Aims: The present study was to assess depression, anxiety and stress levels in patients with oral lichen planus. Methods: The psychometric evaluation using the Depression Anxiety Stress Scale (DASS-42 questionnaire was carried out, by the same investigator on all members of group 1 (Oral Lichen Planus and group 2 (Control. DASS-42 questionnaire consists of 42 symptoms divided into three subscales of 14 items: Depression scale, anxiety scale, and stress scale. Statistical Analysis Used: The Student t test was used to determine statistical difference for both the groups and to evaluate for significant relationships among variables. Results: Psychological assessment using DASS-42 reveals lichen planus patients showed higher frequency of psychiatric co morbidities like depression, anxiety and stress compared to control group. Conclusions: This study has provided evidence that the DASS-42 questionnaire is internally consistent and valid measures of depression, anxiety, and stress. Psychiatric evaluation can be considered for patients with oral lichen planus with routine treatment protocols are recommended. DASS-42 Questionnaire can also be used to determine the level of anxiety, stress and depression in diseases of the oral mucosa like recurrent apthous stomatitis, burning mouth syndrome and TMD disorders.

    Full Text Available Anxiety is an important factor in foreign language learning. Very few studies have been done on English as a Foreign Language (EFL Saudi students in listening classes. Therefore, this pilot study was aimed at exploring the causes of listening comprehension anxiety from EFL Saudi learners’ perspectives at Majmaah University, Saudi Arabia. The pilot study involved two students who were selected based on the following criteria: 1 Only Saudi male undergraduate students who enrolled in Preparatory Year Program (PYP at Majmaah University would be involved in this study, 2 The students who had studied or lived in native English speaking countries would be excluded. The researcher used pseudonyms to refer to the participants as Mohammad and Ismail. This study employed a qualitative case study research design. The data were collected through Semi-structured interviews with the participants. The interview sessions were audiotaped and transcribed. The results show that the participants experienced a high level of anxiety when doing the listening comprehension tasks. Three main causes of listening comprehension anxiety emerged from this study: 1 the problematic nature of listening comprehension, 2 the classroom atmosphere, and 3 the low English proficiency of the students.

    Burns are physically, psychologically and economically challenging injuries, and the factors leading to them are many and under-studied. The aim of the current study was to assess level of anxiety, depression and self-esteem in burn patients, and look at various burn-related variables that affect them. This cross-sectional study included 100 patients with burn injuries admitted to a tertiary care private hospital in an urban metropolis in India. The patients were assessed for anxiety, depression and self-esteem using the Hamilton anxiety rating scale, Hamilton depression rating scale and Rosenberg self-esteem scale respectively. Assessment was carried out within 2-8 weeks of injury following medical stabilization. The data was tabulated and statistically analyzed. The study sample was predominantly male (54%), married (69%), with a mean age of 34.1 ± 10.8 years. Accidental burns (94%) were the most common modality of injury. The majority (46%) suffered burns involving 20-59% total body surface area (TBSA), and facial burns were present (57%). No significant association was found between TBSA and anxiety, depression or self-esteem, and the same was true for facial burns. Deep burns, however, were significantly associated with anxiety (p=0.03) and depression (p=0.0002). High rates of anxiety and depression are associated with burn injuries and related to burn depth. Adjustment and recovery in these patients depends on various other factors like the patient's psychological status, nature/extent of the injury and ensuing medical care. Further research is warranted to reveal the magnitude and predictors of psychological problems in burn patients.
