Trust is essential to the development of healthy, secure, and satisfying relationships (Simpson, 2007a). Attachment styles provide a theoretical framework for understanding how individuals respond to partner behaviors that either confirm or violate trust (Hazan & Shaver, 1994). The current research aimed to identify how trust and attachment anxiety might interact to predict different types of jealousy and physical and psychological abuse. We expected that when experiencing lower levels of trust, anxiously attached individuals would report higher levels of both cognitive and behavioral jealousy as well as partner abuse perpetration. Participants in committed romantic relationships ( N = 261) completed measures of trust, attachment anxiety and avoidance, jealousy, and physical and psychological partner abuse in a cross-sectional study. Moderation results largely supported the hypotheses: Attachment anxiety moderated the association between trust and jealousy, such that anxious individuals experienced much higher levels of cognitive and behavioral jealousy when reporting lower levels of trust. Moreover, attachment anxiety moderated the association between trust and nonphysical violence. These results suggest that upon experiencing distrust in one's partner, anxiously attached individuals are more likely to become jealous, snoop through a partner's belongings, and become psychologically abusive. The present research illustrates that particularly for anxiously attached individuals, distrust has cascading effects on relationship cognitions and behavior, and this should be a key area of discussion during therapy.

Full Text Available BACKGROUND: The ability to communicate anxiety through chemosensory signals has been documented in humans by behavioral, perceptual and brain imaging studies. Here, we investigate in a time-sensitive manner how chemosensory anxiety signals, donated by humans awaiting an academic examination, are processed by the human brain, by analyzing chemosensory event-related potentials (CSERPs, 64-channel recording with current source density analysis. METHODOLOGY/PRINCIPAL FINDINGS: In the first study cerebral stimulus processing was recorded from 28 non-socially anxious participants and in the second study from 16 socially anxious individuals. Each individual participated in two sessions, smelling sweat samples donated from either female or male donors (88 sessions; balanced session order. Most of the participants of both studies were unable to detect the stimuli olfactorily. In non-socially anxious females, CSERPs demonstrate an increased magnitude of the P3 component in response to chemosensory anxiety signals. The source of this P3 activity was allocated to medial frontal brain areas. In socially anxious females chemosensory anxiety signals require more neuronal resources during early pre-attentive stimulus processing (N1. The neocortical sources of this activity were located within medial and lateral frontal brain areas. In general, the event-related neuronal brain activity in males was much weaker than in females. However, socially anxious males processed chemosensory anxiety signals earlier (N1 latency than the control stimuli collected during an ergometer training. CONCLUSIONS/SIGNIFICANCE: It is concluded that the processing of chemosensory anxiety signals requires enhanced neuronal energy. Socially anxious individuals show an early processing bias towards social fear signals, resulting in a repression of late attentional stimulus processing.

This study investigated whether parenting behaviors differed between parents of 68 clinically anxious children and 106 healthy control children aged 4-12 years. The effects of parent gender, child gender and child age on parenting were explored. Mothers and fathers completed a questionnaire to assess parenting behaviors in for children hypothetically anxious situations. Results showed that parents of clinically anxious children reported more anxiety-enhancing parenting (reinforcement of dependency and punishment) as well as more positive parenting (positive reinforcement). For the clinical sample, fathers reported using more modeling/reassurance than mothers, and parents reported using more force with their 4-7-year-olds than with their 8-12-year-olds. No interaction effects were found for child gender with child anxiety status on parenting. Results indicate that for intervention, it is important to measure parenting behaviors, and to take into account father and mother differences and the age of the child. Copyright © 2015 Elsevier Ltd.

Objective Examine the therapeutic relationship with cognitive-behavioral therapists and with pharmacotherapists for youth from the Child/Adolescent Anxiety Multimodal Study (CAMS; Walkup et al., 2008). The therapeutic relationship was examined in relation to treatment outcomes. Method Participants were 488 youth (ages 7-17; 50% male) randomized to cognitive-behavioral therapy (CBT; Coping cat), pharmacotherapy (SRT; sertraline), their combination, or pill placebo. Participants met DSM-IV criteria for generalized anxiety disorder, social phobia, and/or separation anxiety disorder. The therapeutic relationship was assessed by youth-report at weeks 6 and 12 of treatment using the Child's Perception of Therapeutic Relationship scale. Outcome measures (Pediatric Anxiety Rating Scale; Clinical Global Impressions Scales) were completed by Independent Evaluators blind to condition. Results For youth who received CBT only, a stronger therapeutic relationship predicted positive treatment outcome. In contrast, the therapeutic relationship did not predict outcome for youth receiving sertraline, combined treatment, or placebo. Conclusions A therapeutic relationship may be important for anxious youth who receive CBT alone. PMID:23750468

Emerging adult cortisol response during family interaction predicts change in EA anxious behavior during the transition to college (Gans & Johnson, in press). In the present study, we take an additional step toward integrating family systems research and physiology by including assessment of parent physiology. We collect salivary cortisol from parents and emerging-adults during triadic family interaction. Emerging adults (N = 101) between the ages of 17 and 19 were assessed at three time points across their first college year: the summer before college, fall and spring semesters. Two parents accompanied the emerging adult child to the summer assessment; all family members provided four saliva samples each at 20-minute intervals. Later assessments of emerging adults included measures of internalizing behaviors. Parents’ cortisol secretion patterns during family interaction predict their emerging adult child’s cortisol secretion pattern, parent perceptions of the family environment, and emerging adult children’s internalizing behavior during the college transition. Different patterns of results emerged for mothers’ and fathers’ cortisol response to family interaction, and for families with sons or with daughters. The approach taken by this study provides a first step toward understanding how interrelationships among elements of physiology and family functioning contribute to adjustment during major life transitions.

Attachment theory has increasingly been utilized to understand the etiology of sexual violence, and anxious attachment appears to be especially informative in this domain. We investigate the influence of general anxious attachment and specific anxious attachment on hostile masculine attitudes to predict male-perpetrated sexual assault. We hypothesize that hostile masculinity will mediate the relationship between general anxious attachment style and sexual assault perpetration (Hypothesis 1) and the relationship between specific anxious attachment to the assaulted woman and sexual assault perpetration (Hypothesis 2). Men ( N = 193) completed the Sexual Experiences Survey (SES) to determine sexual assault history and completed measures of general attachment style, specific attachment to the woman involved in the sexual activity, and measures of hostile masculine attitudes. Results support the hypothesized mediation models, such that general anxious attachment and specific anxious attachment are significantly associated with hostile masculinity, which in turn, predicts the likelihood of male-perpetrated sexual assault. The findings suggest that the unique characteristics of anxious attachment may escalate into hostile masculinity, which then increases the likelihood of sexual assault perpetration. This research is the first to investigate attachment bonds to the woman involved in the sexual activity and likelihood of sexual assault perpetration against the same woman.

Neurobiology of anxious depression: a review.

Anxious depression is a common, distinct clinical subtype of major depressive disorder (MDD). This review summarizes current neurobiological knowledge regarding anxious depression. Peer-reviewed articles, published January 1970 through September 2012, were identified via PUBMED, EMBASE, and Cochrane Library, using the following key words: anxious depression electroencephalography (EEG), anxious depression functional magnetic resonance imaging (fMRI), anxious depression genetics, anxious depression neurobiology, and anxious melancholia neurobiology. Despite a general dearth of neurobiological research, the results suggest that anxious depression-when defined either syndromally or dimensionally-has distinct neurobiological findings that separate it from nonanxious depression. Structural neuroimaging, EEG, genetics, and neuropsychiatric studies revealed differences in subjects with anxious depression compared to other groups. Endocrine differences between individuals with anxious depression and those with nonanxious depression have also been noted, as evidenced by abnormal responses elicited by exogenous stimulation of the system. Despite these findings, heterogeneity in the definition of anxious depression complicates the results. Because exploring the neurobiology of this depressive subtype is important for improving diagnosis, prognosis, and treatment, enrichment strategies to decrease heterogeneity within the field should be employed for future research. © 2013 Wiley Periodicals, Inc.

Family characteristics of anxious ADHD children: preliminary results.

Kepley, Hayden O; Ostrander, Rick

2007-02-01

To investigate the family environments of children in a community sample with ADHD and co-occurring anxiety. Family Environment Scale, Behavioral Assessment System for Children, and Structured Clinical Interview are administered to parents of children with ADHD with and without anxiety. ADHD families are uniformly less cohesive and expressive and possess more conflict than families representing the community sample. In contrast to community or nonanxious ADHD families, anxious ADHD families do not encourage independence and tend to be distinctly less assertive, self-sufficient, and autonomous. Although anxious and nonanxious ADHD children tend to have a uniformly high incidence of maternal ADHD, mothers of anxious ADHD children tend to display a much higher incidence of substance/alcohol abuse than either nonanxious or community participants. Findings are consistent with the notion that an insular, dependent, and somewhat controlling family environment characterizes families of children with ADHD and comorbid childhood anxiety.

The present study extended the findings of Muris et al. [Muris, P., Meesters, C., Merckelbach, H., & Hulsenbeck, P. (2000). Worry in children is related to perceived parental rearing and attachment. Behavior Research and Therapy, 38, 487-497] regarding the relations between perceived parental rearing behaviors, self-reported attachment style, and worry in a community sample to a clinical sample of anxious children. Sixty-four children and adolescents, aged 7-18 years, with a primary anxiety disorder completed (a) the EMBU-C, a questionnaire measuring perceptions of parental rearing behaviors, (b) a single-item measure of attachment style, and (c) an index of worry severity. Findings revealed that child rated parental rearing behaviors, particularly parental rejection, were positively related to child worry. Self-reported attachment style was also related to worry, such that children who classified themselves as ambivalently attached reported higher levels of worry than did children who classified themselves as securely attached. Parenting style and attachment were found to make independent contributions to worry. The results are compared to those from Muris et al.'s community study, and implications for future research are discussed.

Adolescence is the time of peak onset for many anxiety disorders, particularly Social Anxiety Disorder. Research using simulated social interactions consistently finds differential activation in several brain regions in anxious (vs non-anxious) youth, including amygdala, striatum and medial prefrontal cortex. However, few studies examined the anticipation of peer interactions, a key component in the etiology and maintenance of anxiety disorders. Youth completed the Chatroom Task while undergoing functional magnetic resonance imaging. Patterns of neural activation were assessed in anxious and non-anxious youth as they were cued to anticipate social feedback from peers. Anxious participants evidenced greater amygdala activation and rostral anterior cingulate (rACC)↔amygdala coupling than non-anxious participants during anticipation of feedback from peers they had previously rejected; anxious participants also evidenced less nucleus accumbens activation during anticipation of feedback from selected peers. Finally, anxiety interacted with age in rACC: in anxious participants, age was positively associated with activation to anticipated feedback from rejected peers and negatively for selected peers, whereas the opposite pattern emerged for non-anxious youth. Overall, anxious youth showed greater reactivity in anticipation of feedback from rejected peers and thus may ascribe greater salience to these potential interactions and increase the likelihood of avoidance behavior. © The Author (2014).

Research has revealed significant heterogeneity in the group-level peer outcomes associated with anxious-withdrawal, but little is known about possible sources of this heterogeneity during early adolescence. This study of 271 young adolescents (49 % female; M age = 11.54 years) examined whether the concurrent and short-term longitudinal (3 month period) associations between peer-nominated anxious-withdrawn behaviors and three group-level peer outcomes (overt victimization, peer acceptance, popularity) varied as a function of peer-valued characteristics (humor, prosocial behavior, physical attractiveness, athletic ability) and gender, after accounting for the effects of involvement in mutual friendships. Regression analyses revealed that the associations between anxious-withdrawal and peer outcomes were moderated by peer-valued characteristics and, in many cases, gender. For example, anxious-withdrawal was related positively to overt victimization for all adolescents who were high in prosocial behavior. But, anxious-withdrawal was related negatively to popularity for adolescent boys who were high in prosocial behavior and adolescent girls who were low in prosocial behavior. Anxious-withdrawal also predicted increases in acceptance for adolescent girls who were high in humor, but decreases in acceptance for adolescent boys who were high in humor. Several additional moderator effects were found for boys only. The findings highlight the importance of considering the unique constellation of characteristics displayed by anxious-withdrawn young adolescents in studies on peer experiences at the group-level of social complexity.

Simple arithmetic: not so simple for highly math anxious individuals.

Fluency with simple arithmetic, typically achieved in early elementary school, is thought to be one of the building blocks of mathematical competence. Behavioral studies with adults indicate that math anxiety (feelings of tension or apprehension about math) is associated with poor performance on cognitively demanding math problems. However, it remains unclear whether there are fundamental differences in how high and low math anxious individuals approach overlearned simple arithmetic problems that are less reliant on cognitive control. The current study used functional magnetic resonance imaging to examine the neural correlates of simple arithmetic performance across high and low math anxious individuals. We implemented a partial least squares analysis, a data-driven, multivariate analysis method to measure distributed patterns of whole-brain activity associated with performance. Despite overall high simple arithmetic performance across high and low math anxious individuals, performance was differentially dependent on the fronto-parietal attentional network as a function of math anxiety. Specifically, low-compared to high-math anxious individuals perform better when they activate this network less-a potential indication of more automatic problem-solving. These findings suggest that low and high math anxious individuals approach even the most fundamental math problems differently. © The Author (2017). Published by Oxford University Press.

Anxiety in children age 8 years and above has been successfully treated with cognitive behavioral therapy (CBT). However, the efficacy of CBT for anxious children ages 4-7 years has not, to date, been fully investigated. This paper piloted a CBT intervention targeting child anxiety that was delivered exclusively to parents of 26 children with anxiety symptoms ages 4-7 years. The intervention consisted of four 2-hour group sessions of four to six parents (couples). These group sessions were followed by four individual telephone sessions, once per week across a 4-week period. The pre- and postintervention assessment involved measures of multiple constructs of child anxiety (anxiety symptoms, children's fears, behavioral inhibition, and internalizing symptoms) from multiple informants (parents, children, and teachers). Parents also reported parenting strategies they were likely to use to manage their children's anxiety pre- and postintervention. Results indicated a significant decrease in child anxiety and behavioral inhibition as reported by parents and teachers. Furthermore, mothers reported significant increases in their use of positive reinforcement, and modeling and reassurance, and a significant decrease in their use of reinforcement of dependency directly after treatment. Taken together, parent-directed CBT appears to be an effective approach for treating children ages 4-7 years with anxiety symptoms. Limitations of the current research are discussed.

Internet Addiction Disorder (IAD) is an emerging psychiatric disorder, assimilable to impulse control problems and related to maladaptive use of new networks and social and virtual technologies. Our study aims to analyze the presence of IAD among adolescents and to study the correlation with social interaction anxiousness. We investigated also the possibility that the Social Network (SN) represent a source of risk for the development of IAD. The test group was composed of 250 subjects, aged between 14 and 18 years. They were administered: Young's IAT; IAS (Interaction Anxiousness Scale), AAS (Audience Anxiousness Scale) and SISST (Social Interaction Self-Statement Test) to analyze the dimension of social interaction anxiousness. We found a rate of 2% of the IAD. The SN are the most common use of the Net in our sample, but not the most clicked sites by subjects with IAD. It should be noted, finally, a correlation between social interaction anxiety and IAD, but not a significant difference in scores of social anxiousness scales based on the SN use/non-use. The use of SN intended as single variable doesn't correlate with increased risk for IAD, or for increased social interaction anxiousness. However, if associated with prolonged use of the net for 5-6 hours or more, or concomitant use of chat rooms and/or net gambling, we find a more significant risk of psychopathology. The data presented require further investigations, in order to guide new pathogenetic models and appropriate intervention strategies.

Suicidal behavior is frequently associated with a history of childhood abuse yet it remains unclear precisely how early life adversity may increase suicide risk later in life. As such, our aim was to examine whether lifetime trajectories of disruptiveness and anxiousness trait dysregulation explain the association between childhood adversity and suicidal behavior; and moreover, to test the potential modifying effects of mental disorders on these associations. A sample of 1776 individuals from a prospective school-based cohort followed longitudinally for over 22 years was investigated. We tested the influence of disruptiveness and anxiousness trajectories from age 6 to 12 years on the association between childhood adversity (i.e. sexual and physical abuse) and history of suicide attempts (SA) using logistic regression models. Both adolescent externalizing and internalizing Axis I disorders and gender were tested as potential modifiers of these associations. Four distinct longitudinal trajectories were identified for both disruptiveness and anxiousness. The high disruptiveness trajectory accounted for the association between childhood adversity and SA, but only for females. The high anxiousness trajectory also explained the association between adversity and SA; however, in this case it was not sex but mental disorders that influenced the potency of the mediating effect. More specifically, anxiousness fully explained the effect of adversity on SA in the presence of externalizing disorders, whereas in the absence of these disorders, this effect was significantly attenuated. This study provides evidence that both disruptiveness and anxiousness play an important role in explaining the relationship between childhood adversity and SA.

Dominance is one of the most pervasive and important behaviors among wolves in a pack, yet its significance in free-ranging packs has been little studied. Insights into a behavior can often be gained by examining unusual examples of it. In the High Arctic near Eureka, Nunavut, Canada, we videotaped and described an unusually prolonged and intensive behavioral bout between an adult male Gray Wolf (Canis lupus) and a male member of his pack, thought to be a maturing son. With tail raised, the adult approached a male pack mate about 50 m from us and pinned and straddled this packmate repeatedly over 6.5 minutes, longer than we had ever seen in over 50 years of studying wolves. We interpreted this behavior as an extreme example of an adult wolf harassing a maturing offspring, perhaps in prelude to the offspring?s dispersal.

A Neurorobotic Platform to Test the Influence of Neuromodulatory Signaling on Anxious and Curious Behavior

Directory of Open Access Journals (Sweden)

Jeffrey L Krichmar

2013-02-01

Full Text Available The vertebrate neuromodulatory systems are critical for appropriate value-laden responses to environmental challenges. Whereas changes in the overall level of dopamine have an effect on the organism’s reward or curiosity seeking behavior, changes in the level of serotonin can affect its level of anxiety or harm aversion. Moreover, top-down signals from frontal cortex can exert cognitive control on these neuromodulatory systems. The cholinergic and noradrenergic systems affect the ability to filter out noise and irrelevant events. We introduce a neural network for action selection that is based on these principles of neuromodulatory systems. The algorithm tested the hypothesis that high levels of serotonin lead to withdrawn behavior by suppressing dopaminergic action and that high levels of dopamine or low levels of serotonin lead to curious, exploratory behavior. Furthermore, the algorithm tested the idea that top-down signals from the frontal cortex to neuromodulatory areas are critical for an organism to cope with both stressful and novel events. The neural network was implemented on an autonomous robot and tested in an open field paradigm. The open field test is often used to test for models anxiety or exploratory behavior in the rodent and allows for qualitative comparisons with the neurorobot’s behavior. The present neurorobotic experiments can lead to a better understanding of how neuromodulatory signaling affects the balance between anxious and curious behavior. Therefore, this experimental paradigm may also be informative in exploring a wide range of neurological diseases such as anxiety, autism, attention deficit disorders, and obsessive-compulsive disorders.

Anxious and avoidant attachment, vibrator use, anal sex, and impaired vaginal orgasm.

Science.gov (United States)

Costa, Rui M; Brody, Stuart

2011-09-01

Disturbances in intimate relationships are among the risk factors for female sexual dysfunction. Insecure styles of anxious attachment (preoccupations about abandonment) and avoidant attachment (avoidance of closeness in relationships) are robustly associated with sexual problems, relationship difficulties, and several indices of poorer physical and mental health. Similar indices of poorer sexual, relationship, and health functioning are associated with impairment of orgasm triggered by penile-vaginal stimulation (vaginal orgasm), but unrelated or related to greater frequency of other sexual behaviors. However, research examining the differential association of sexual activities with insecure attachment styles has been lacking. The aim of this study was to test the hypotheses that insecure attachment styles are associated with lesser vaginal orgasm consistency, and are unrelated or directly related to greater frequency of other sexual behaviors. Seventy coitally experienced women recruited at a Scottish university completed the Revised Experience in Close Relationships scale, and reported their frequency of various sexual behaviors (and corresponding orgasms) in a recent representative month. The main outcome measures for this study are multivariate correlations of various sexual activities with insecure attachment styles, age, and social desirability response bias. Anxious attachment was associated with lesser vaginal orgasm consistency, but with higher frequency of vibrator and anal sex orgasms. Avoidant attachment was associated with higher frequency of vibrator orgasms. Neither anxious nor avoidant attachment was associated with lifetime number of penile-vaginal intercourse partners. The results provide evidence that inability to attain a vaginal orgasm is associated with anxious attachment, among other indices of poorer mental health and relatedness. Vaginal orgasm might be the relevant sexual activity for the maintenance of a secure attachment style with a

Anxious, threatened, and also unethical: how anxiety makes individuals feel threatened and commit unethical acts.

Kouchaki, Maryam; Desai, Sreedhari D

2015-03-01

People often experience anxiety in the workplace. Across 6 studies, we show that anxiety, both induced and measured, can lead to self-interested unethical behavior. In Studies 1 and 2, we find that compared with individuals in a neutral state, anxious individuals are more willing (a) to participate in unethical actions in hypothetical scenarios and (b) to engage in more cheating to make money in situations that require truthful self-reports. In Studies 3 and 4, we explore the psychological mechanism underlying unethical behaviors when experiencing anxiety. We suggest and find that anxiety increases threat perception, which, in turn, results in self-interested unethical behaviors. Study 5 shows that, relative to participants in the neutral condition, anxious individuals find their own unethical actions to be less problematic than similar actions of others. In Study 6, data from subordinate-supervisor dyads demonstrate that experienced anxiety at work is positively related with experienced threat and unethical behavior. We discuss the theoretical and practical implications of our findings. PsycINFO Database Record (c) 2015 APA, all rights reserved.

Thinking anxious, feeling anxious, or both? Cognitive bias moderates the relationship between anxiety disorder status and sympathetic arousal in youth.

Cognitive bias and physiological arousal are two putative markers that may underlie youth anxiety. However, data on relationships between cognitive bias and arousal are limited, and typically do not include behavioral measurement of these constructs in order to tap real-time processes. We aimed to examine the relationship between performance-based cognitive bias and sympathetic arousal during stress in clinically anxious and typically-developing youth. The sample included children and adolescents ages 9 to 17 (Mean age=13.18, SD=2.60) who either met diagnostic criteria for primary generalized anxiety, social phobia, or separation anxiety (N=24) or healthy controls who had no history of psychopathology (N=22). Youth completed performance-based measures of attention and interpretation bias. Electrodermal activity was assessed while youth participated in the Trier Social Stress Test for Children (TSST-C; Buske-Kirschbaum, Jobst, & Wustmans, 1997). A mixed models analysis indicated significant linear and non-linear changes in skin conductance, with similar slopes for both groups. Interpretation bias, but not attention bias, moderated the relationship between group status and sympathetic arousal during the TSST-C. Arousal trajectories did not differ for anxious and healthy control youth who exhibited high levels of threat interpretation bias. However, for youth who exhibited moderate and low levels of interpretation bias, the anxious group demonstrated greater arousal slopes than healthy control youth. Results provide initial evidence that the relationship between anxiety status and physiological arousal during stress may be moderated by level of interpretation bias for threat. These findings may implicate interpretation bias as a marker of sympathetic reactivity in youth. Implications for future research and limitations are discussed. Published by Elsevier Ltd.

Adapting behavior to changes in the environment is a crucial ability for survival but such adaptation varies widely across individuals. Here, we asked how humans alter their economic decision-making in response to emotional cues, and whether this is related to trait anxiety. Developing an emotional decision-making task for functional magnetic resonance imaging, in which gambling decisions were preceded by emotional and non-emotional primes, we assessed emotional influences on loss aversion, the tendency to overweigh potential monetary losses relative to gains. Our behavioral results revealed that only low-anxious individuals exhibited increased loss aversion under emotional conditions. This emotional modulation of decision-making was accompanied by a corresponding emotion-elicited increase in amygdala-striatal functional connectivity, which correlated with the behavioral effect across participants. Consistent with prior reports of 'neural loss aversion', both amygdala and ventral striatum tracked losses more strongly than gains, and amygdala loss aversion signals were exaggerated by emotion, suggesting a potential role for this structure in integrating value and emotion cues. Increased loss aversion and striatal-amygdala coupling induced by emotional cues may reflect the engagement of adaptive harm-avoidance mechanisms in low-anxious individuals, possibly promoting resilience to psychopathology. © The Author (2015).

Because suicide attempts are multi-determined events, multiple pathways to suicidal behaviors exist. However, as a low-frequency behavior, within group differences in trajectories to attempts may not emerge when examined in samples including non-attempters. We used longitudinal latent profile analysis to identify subtypes specific for suicide attempters based on longitudinal trajectories of childhood clinical symptoms (i.e., depression, anxiety, and aggression measured in 2nd, 4th-7th grades) for 161 young adults (35.6% male; 58.6% African American) who attempted suicide between ages 13-30 from a large, urban community-based, longitudinal prevention trial (n = 2311). Differences in psychiatric diagnoses, suicide attempt characteristics, criminal history and traumatic stress history were studied. Three subtypes emerged: those with all low (n = 32%), all high (n = 16%), and high depressive/anxious, but low aggressive (n = 52%) symptoms. Those with the highest levels of all symptoms were significantly more likely to report a younger age of suicide attempt, and demonstrate more substance abuse disorders and violent criminal histories. Prior studies have found that childhood symptoms of depression, anxiety and aggression are malleable targets; interventions directed at each reduce future risk for suicidal behaviors. Our findings highlight the link of childhood aggression with future suicidal behaviors extending this research by examining childhood symptoms of aggression in the context of depression and anxiety.

Full Text Available Stress is a major risk factor in the onset of several neuropsychiatric disorders including anxiety and depression. Although several studies have shown that social isolation stress during postweaning period induces behavioral and brain molecular changes, the effects of social isolation on behavior during adulthood have been less characterized. Aim of this work was to investigate the relationship between the behavioral alterations and brain molecular changes induced by chronic social isolation stress in adult male mice. Plasma corticosterone levels and adrenal glands weight were also analyzed. Socially isolated (SI mice showed higher locomotor activity, spent less time in the open field center, and displayed higher immobility time in the tail suspension test compared to group-housed (GH mice. SI mice exhibited reduced plasma corticosterone levels and reduced difference between right and left adrenal glands. SI showed lower mRNA levels of the BDNF-7 splice variant, c-Fos, Arc, and Egr-1 in both hippocampus and prefrontal cortex compared to GH mice. Finally, SI mice exhibited selectively reduced mGluR1 and mGluR2 levels in the prefrontal cortex. Altogether, these results suggest that anxious- and depressive-like behavior induced by social isolation stress correlates with reduction of several neuroplasticity-related genes in the hippocampus and prefrontal cortex of adult male mice.

Previous studies using adult observers are inconsistent with regard to social skills deficits in nonclinical socially anxious youth. The present study investigated whether same age peers perceive a lack of social skills in the socially anxious. Twenty high and 20 low socially anxious adolescents (13-17 years old) were recorded giving a 5-min speech. Unfamiliar peer observers (12-17 years old) viewed the speech samples and rated four social skills: speech content, facial expressions, posture and body movement, and way of speaking. Peer observers perceived high socially anxious adolescents as significantly poorer than low socially anxious adolescents on all four social skills. Moreover, for all skills except facial expressions, group differences could not be attributed to adolescents' self-reported level of depression. We suggest that therapists take the perceptions of same age peers into account when assessing the social skills of socially anxious youth.

Childhood sleep problems have been associated with a range of adverse cognitive and academic outcomes, as well as increased impulsivity and emotional disorders such as anxiety and depression. The aim of the study was to examine subjective reports of sleep-related problems in children with anxiety disorders during school and weekend nights. Thirty-seven children with clinically-diagnosed anxiety disorders and 26 non-clinical children aged 7-12 years completed an on-line sleep diary to track sleep patterns across school nights and weekend nights. Anxious children reported going to bed significantly later (p=0.03) and had significantly less sleep (p=0.006) on school nights compared to non-anxious children. No significant differences in sleep onset latency, number of awakenings or time awake during the night, daytime sleepiness, or fatigue were found between the two groups. On the weekends, anxious children fell asleep quicker and were less awake during the night than on weeknights. School-aged anxiety disordered children showed a sleep pattern that differs from their non-anxious peers. Although the mean 30 min less sleep experienced by anxious children may initially seem small, the potential consequences on daytime performance from an accumulation of such a sleep deficit may be significant, and further investigation is warranted.

Purpose To examine the prevalence and correlates of anxiety in a community sample of adolescents. Knowing the prevalence and characteristics of anxious adolescents is valuable to improve anxiety prevention strategies and interventions. Design Cross-sectional data about anxiety were collected via a school survey from a community sample of Norwegian adolescents aged 12-17 ( N = 1719). Methods Based on scores from the Spence Children's Anxiety Scale, the adolescents were categorized as not anxious or anxious. Logistic regression analysis was performed to access the impact of each factor on the likelihood that participants would report an elevated level of anxiety. Results A total of 22% of the adolescents were categorized as anxious. Female gender, experienced negative life events, low social support, and low self-efficacy were associated with elevated level of anxiety. Conclusions The high prevalence of anxiety in adolescents demonstrates the importance of improved prevention interventions targeting anxious adolescents. We argue that addressing is the responsibility of not only the individual adolescents and their families but also schools, school health services, and policy makers. School-based interventions that increase social support and self-efficacy would probably be particularly beneficial for anxious adolescents.

Vigilance in the laboratory predicts avoidance in the real world: A dimensional analysis of neural, behavioral, and ecological momentary data in anxious youth

Full Text Available Vigilance and avoidance of threat are observed in anxious adults during laboratory tasks, and are posited to have real-world clinical relevance, but data are mixed in anxious youth. We propose that vigilance-avoidance patterns will become evident in anxious youth through a focus on individual differences and real-world strategic avoidance. Decreased functional connectivity between the amygdala and prefrontal cortex (PFC could play a mechanistic role in this link. 78 clinically anxious youth completed a dot-probe task to assess vigilance to threat while undergoing fMRI. Real-world avoidance was assessed using Ecological Momentary Assessment (EMA of self-reported suppression and distraction during negative life events. Vigilance toward threat was positively associated with EMA distraction and suppression. Functional connectivity between a right amygdala seed region and dorsomedial and right dorsolateral PFC regions was inversely related to EMA distraction. Dorsolateral PFC-amygdalar connectivity statistically mediated the relationship between attentional vigilance and real-world distraction. Findings suggest anxious youth showing attentional vigilance toward threat are more likely to use suppression and distraction to regulate negative emotions. Reduced PFC control over limbic reactivity is a possible neural substrate of this pattern. These findings lend ecological validity to laboratory vigilance assessments and suggest PFC-amygdalar connectivity is a neural mechanism bridging laboratory and naturalistic contexts.

Trait anxiety has been shown to cause significant impairments on attentional tasks. Current research has identified alpha band frequency differences between low-trait and high-trait anxious individuals. Here, we further investigated the underlying alpha band frequency differences between low-trait and high-trait anxious individuals during their resting state and the completion of an inhibition executive functioning task. Using human participants and quantitative electroencephalographic recordings, we measured alpha band frequency in individuals both high and low in trait anxiety during their resting state, and while they completed an Eriksen Flanker Task. Results indicated that high-trait anxious individuals exhibit a desynchronization in alpha band frequency from a resting state to when they complete the Eriksen Flanker Task. This suggests that high-trait anxious individuals maintain fewer attentional resources at rest and must martial resources for task performance as compared with low-trait anxious individuals, who appear to maintain stable cognitive resources between rest and task performance. These findings add to the cognitive neuroscience literature surrounding the role of alpha band frequency in low-trait and high-trait anxious individuals.

Diliberto, Rachele A; Kearney, Christopher A

2016-01-01

Selective mutism (SM) is a debilitating condition in which a child does not speak in social situations where speech is expected. The clinical conceptualization of SM has been debated historically, with evidence pointing partly to anxious and oppositional behavior profiles. Behavioral characteristics were examined in a clinical sample of 57 youth formally diagnosed with selective mutism. Parents rated children across internalizing and externalizing behaviors on the Child Behavior Checklist. Eighteen highly rated items were subjected to exploratory and then confirmatory factor analysis. Anxiety and oppositional behavior factors were derived. The anxious behavior profile was associated with social anxiety disorder symptoms, social problems, and aggressive behaviors but not oppositional defiant disorder symptoms. The oppositional behavior profile was associated with aggressive behaviors, oppositional defiant disorder symptoms, social problems, and inversely to social anxiety disorder symptoms. Results are consistent with emerging research regarding subgroups of children with SM. Behavior profiles are discussed as well with respect to assessment and treatment implications. Readers will learn about the nature of children with selective mutism as well as behaviors that differentiate anxious and oppositional behavior profiles. Items that comprise anxious and oppositional behavior profiles are presented. These item profiles may have ramifications for assessment and treatment. Copyright © 2015 Elsevier Inc.

Effects of Prolonged Silver Nanoparticle Exposure on the Contextual Cognition and Behavior of Mammals

Directory of Open Access Journals (Sweden)

Anna Antsiferova

2018-04-01

Full Text Available Silver nanoparticles have been widely used in the lighting and food industries, in medicine, and in pharmaceutics as an antiseptic agent. Recent research demonstrates that, after prolonged oral administration, silver nanoparticles may cross the blood-brain barrier and accumulate in the brain in rather high amounts. In ex vivo experiments, it has also been shown that silver nanoparticles demonstrate neurotoxicity. The objective of this work was to answer the questions whether silver nanoparticles change cognitive and behavioral functions of mammals after prolonged administration if silver nanoparticles have accumulated in the brain. C57Bl/6 male mice were orally exposed to PVP-coated silver nanoparticles daily for 30, 60, 120 and 180 days. Control mice were exposed to distilled water. After that they were tested in the Open Field, Elevated Plus Maze, Light-Dark Box and contextual fear conditioning task. The data have shown that the experimental mice went through three periods of switching in the behavior caused by adaptation to the toxic silver nanoparticles: anxiety, appearance of research instinct and impairment of long-term memory. This provides evidence of the hazardous effect of silver nanoparticles, which appears after long periods of silver nanoparticle oral administration.

Exposure to violence is traumatic and an important source of mental health disturbance, yet the factors associated with victimization remain incompletely understood. The aim of the present study was to investigate factors related to vulnerability to depression-like behaviors in females. An animal model of intimate partner violence, which was previously shown to produce long-lasting behavioral effects in females as a result of male partner aggression, was used. The associations among the degree of partner aggression, the long-term consequences on depressive-like behavior, and the impact of the anxious temperament of the female were examined. In a separate group, pre-selected neural markers were evaluated in the amygdala and the lateral septum of females. Expression was examined by analyses of targeted candidate genes, serotonin transporter (slc6a4), vasopressin receptor 1a, (avpr1a), and oxytocin receptor (oxtr). Structural equation modeling revealed that the female's temperament moderated depressive-like behavior that was induced by cohabitation aggression from the male partner. More specifically, increased floating in the forced swim test following male aggression was most apparent in females exhibiting more anxiety-like behavior (i.e., less open arm exploration in an elevated plus-maze) prior to the cohabitation. Aggression reduced slc6a4 levels in the lateral septum. However, the interaction between partner aggression and the anxious temperament of the female affected the expression of avpr1a in the amygdala. Although, aggression reduced levels of this marker in females with high anxiety, no such pattern was observed in females with low anxiety. These results identify important characteristics in females that moderate the impact of male aggression. Furthermore, these results provide potential therapeutic targets of interest in the amygdala and the lateral septum to help improve post-stress behavioral pathology and increase resilience to social adversity.

To investigate the association of childhood trajectories of anxiousness and disruptiveness with suicide attempts in early adulthood. Prospective cohort study. Public francophone schools in Quebec, Canada, from the 1986 to 1988 school years. Of 4,488 French Canadian children attending kindergarten, a representative group of 1,001 boys and 999 girls was chosen for follow-up. Of these, 1,144 individuals participated in the study during early adulthood. Suicide attempt histories by early adulthood, adjusted odds ratios (ORs) associated with membership in high- vs low-risk trajectories of anxiousness and disruptiveness, moderation (by sex), and mediation (by adolescent Axis I disorders). We observed 4 distinct developmental profiles of anxiousness and disruptiveness and a frequent co-occurrence of similar levels of these traits. In contrast to anxiousness trajectories (OR = 1.60; 95% confidence interval, 1.00-2.65), disruptiveness (OR = 1.80; 95% confidence interval, 1.03-3.13) and joint (OR = 1.88; 95% confidence interval, 1.05-3.37) trajectories made statistically significant contributions to suicide attempts. We found no support for mediation by adolescent anxiety/mood or disruptive disorders. Sex, however, moderated the effect of joint trajectories, increasing the risk of suicide attempts in women (OR = 3.60; Wald chi(2) = 10.93; P anxious and disruptive traits as children. Anxious-disruptive girls and disruptive boys appear to be more likely than their peers to attempt suicide by early adulthood. Preventive efforts will require more research into the possible mechanisms behind this early sex difference, ie, gene-environment interplays and nonpsychiatric mediators.

Post-traumatic stress disorder (PTSD) is manifested as a persistent mental and emotional condition after potentially life-threatening events. Different animal models of PTSD have been developed for neuro-pathophysiology and pharmacological evaluations. A single prolonged stress (SPS) induced animal model has demonstrated to result in specific neuro-endocrinological dysregulation, and behavior abnormalities observed in PTSD. However, animal studies of PTSD have mostly been performed at one time point after SPS exposure. To better understand the development of PTSD-like behaviors in the SPS animal model, and to identify an optimal period of study, we examined depressive behavior, anxiety-like behavior, physical activity and body weight in SPS model rats for two weeks. Our results confirmed the SPS-induced PTSD-like behavior and physical activity observed in previous studies, and indicated that the most pronounced symptomatic behavior changes were observed on day 1 and 7 after SPS exposure, which may involve stress-induced acute hormone changes and unclear secondary neurobiological changes, respectively. These results provide a solid basis for further investigation into the neuro-pathophysiology of or neuropharmacology for PTSD using the SPS rat model. However, for chronic (pharmacological) studies longer than 7 days, a prolonged PTSD animal model should be developed, perhaps using enhanced stimulation. Copyright © 2016 Elsevier B.V.

Full Text Available Theory suggests that individuals with social anxiety manifest unique patterns of cognition with less efficient fluid cognition and unperturbed crystallized cognition; however, empirical support for these ideas remains inconclusive. The heterogeneity of past findings may reflect unreliability in cognitive assessments or the influence of confounding variables. The present study examined the relations among social anxiety and performance on the reliable, newly established NIH Toolbox Cognition Battery. Results indicate that high socially anxious adults performed as well as low anxious participants on all measures of fluid cognition. However, highly socially anxious adults demonstrated enhanced crystallized cognitive abilities relative to a low socially anxious comparison group.

Relative to healthy controls, anxiety-disorder patients show anomalies in classical conditioning that may either result from, or provide a risk factor for, clinically relevant anxiety. Here, we investigated whether healthy participants with enhanced anxiety vulnerability show abnormalities in a challenging affective-conditioning paradigm, in which many stimulus-reinforcer associations had to be acquired with only few learning trials. Forty-seven high and low trait-anxious females underwent MultiCS conditioning, in which 52 different neutral faces (CS+) were paired with an aversive noise (US), while further 52 faces (CS−) remained unpaired. Emotional learning was assessed by evaluative (rating), behavioral (dot-probe, contingency report), and neurophysiological (magnetoencephalography) measures before, during, and after learning. High and low trait-anxious groups did not differ in evaluative ratings or response priming before or after conditioning. High trait-anxious women, however, were better than low trait-anxious women at reporting CS+/US contingencies after conditioning, and showed an enhanced prefrontal cortex (PFC) activation towards CS+ in the M1 (i.e., 80–117 ms) and M170 time intervals (i.e., 140–160 ms) during acquisition. These effects in MultiCS conditioning observed in individuals with elevated trait anxiety are consistent with theories of enhanced conditionability in anxiety vulnerability. Furthermore, they point towards increased threat monitoring and detection in highly trait-anxious females, possibly mediated by alterations in visual working memory. PMID:26113814

Abnormal error monitoring in math-anxious individuals: evidence from error-related brain potentials.

Directory of Open Access Journals (Sweden)

Macarena Suárez-Pellicioni

Full Text Available This study used event-related brain potentials to investigate whether math anxiety is related to abnormal error monitoring processing. Seventeen high math-anxious (HMA and seventeen low math-anxious (LMA individuals were presented with a numerical and a classical Stroop task. Groups did not differ in terms of trait or state anxiety. We found enhanced error-related negativity (ERN in the HMA group when subjects committed an error on the numerical Stroop task, but not on the classical Stroop task. Groups did not differ in terms of the correct-related negativity component (CRN, the error positivity component (Pe, classical behavioral measures or post-error measures. The amplitude of the ERN was negatively related to participants' math anxiety scores, showing a more negative amplitude as the score increased. Moreover, using standardized low resolution electromagnetic tomography (sLORETA we found greater activation of the insula in errors on a numerical task as compared to errors in a non-numerical task only for the HMA group. The results were interpreted according to the motivational significance theory of the ERN.

Anxious depression, defined as major depressive disorder (MDD) accompanied by high levels of anxiety, seems to be both common and difficult to treat, with antidepressant monotherapy often yielding modest results. We sought to examine the relative benefits of antidepressant-anxiolytic cotherapy versus antidepressant monotherapy for patients with anxious depression versus without anxious depression. We conducted a post-hoc analysis of an existing dataset (N=80), from a 3-week, randomized, double-blind trial which demonstrated cotherapy with fluoxetine and clonazepam to result in superior efficacy than fluoxetine monotherapy in MDD. The present analysis involved examining whether anxious depression status served as a predictor and moderator of symptom improvement. Anxious depression status was not found to predict symptom improvement, or serve as a moderator of clinical improvement to cotherapy versus monotherapy. However, the advantage in remission rates in favor of cotherapy versus monotherapy was, numerically, much larger for patients with anxious depression (32.2%) than it was for patients without anxious MDD (9.7%). The respective number needed to treat statistic for these two differences in response rates were, approximately, one in three for patients with anxious depression versus one in 10 for patients without anxious depression. The efficacy of fluoxetine-clonazepam cotherapy compared with fluoxetine monotherapy was numerically but not statistically enhanced for patients with anxious depression than those without anxious depression.

Meta-analytic studies have not confirmed that involving parents in cognitive behavior therapy (CBT) for anxious children is therapeutically beneficial. There is also great heterogeneity in the type of parental involvement included. We investigated parental involvement focused on contingency management (CM) and transfer of control (TC) as a potential outcome moderator using a meta-analysis with individual patient data. Investigators of randomized controlled trials (RCTs) of CBT for anxious children, identified systematically, were invited to submit their data. Conditions in each RCT were coded based on type of parental involvement in CBT (i.e., low involvement, active involvement without emphasis on CM or TC, active involvement with emphasis on CM or TC). Treatment outcomes were compared using a 1-stage meta-analysis. All cases involved in active treatment (894 of 1,618) were included for subgroup analyses. Across all CBT groups, means of clinical severity, anxiety, and internalizing symptoms significantly decreased posttreatment and were comparable across groups. The group without emphasis on CM or TC showed a higher proportion with posttreatment anxiety diagnoses than the low-involvement group. Between posttreatment and 1-year follow-up, the proportion with anxiety diagnoses significantly decreased in CBT with active parental involvement with emphasis on CM or TC, whereas treatment gains were merely maintained in the other 2 groups. CBT for anxious children is an effective treatment with or without active parental involvement. However, CBT with active parental involvement emphasizing CM or TC may support long-term maintenance of treatment gains. RESULTS should be replicated as additional RCTs are published.

Guided by social information processing and affective social competence models, the focal objective of this research was to examine the relations among anxious children's cognitive distortions, social skill competence, and reluctance to express emotion. In addition, we explored whether children's attention control played any meaningful role. Using a sample of 111 anxious children (M age  = 9.63, SD = 0.73; 75.7% girls; 56% Hispanic/Latino), we found that cognitive distortions were negatively related to social competence. In addition, tests of moderated mediation showed that the negative association between cognitive distortions and social skill competence was indirect via reluctance to express emotion, but this only was the case for anxious children with high attention control and for distortions in the academic domain. The findings of this study may set the stage for new ways to conceptualize the role of higher attention control among anxious youth. Statement of contribution What is already known on this subject?

2016-06-01

Full Text Available Depressive and anxious symptoms have a clear impact on the functioning of people. Their appearance seems to be related to the presence of deficits in metacognitive capacities. Mindfulness interventions increase metacognitive awareness through their effect in the decentering capacity. Therefore, the aim of this study was to evaluate the relationship between mindfulness and decentering with anxious and depressive symptomatology respectively. The sample consisted of 465 participants contacted through universities and social networks. Results revealed that both mindfulness and the ability to decenter explain the presence of depressive symptoms while only mindfulness explains the presence of anxiety symptoms. These results are encouraging for intervention in mindfulness with anxious and depressive symptoms and stress the importance of metacognitive processes such as decentering in their development.

2006-05-01

The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals. This group was significantly slower in naming the colour in which threat-related words were displayed compared to neutral words. In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people. This difference was significant even when controlling for the false recall of items that had not been presented during study. These results support the view put forward by Russo, Fox, Bellinger, and Nguyen-Van-Tam (2001) that mood-congruent free recall bias in anxious individuals can be observed if the target material is encoded at a relatively shallow level. Moreover, contrary to Dowens and Calvo (2003), the current results show that the memory advantage for threat-related information in anxious individuals is not a consequence of response bias.

Full Text Available Background: Anxiety about doctors among children is very common. White coat phobia which is a classical conditioning phenomenon is said to be prevalent among children. Objectives: To analyze the association between anxious states of children about dentists and their preference of dentist attire and gender in the dental office. Materials and Methods: The 9-12-year-old middle school children were selected for the study. Children were asked to fill a questionnaire containing children′s fear survey schedule-dental subscale (CFSS-DS and asked to prefer dental attire from four different pictures displaying the single anonymous dentist in four different attires in the same operator. The CFSS-DS gave the anxiety scale, and age, gender, and experience were also plotted against children preference in an apron, protective wear, and gender preference. Results were tabulated and statistically analyzed using Chi-square test. Results: About 718 (62% were scored as anxious children. Of all anxious children, 502 (69.9% had preference of colored attires of the dentist, and 408 (66.8% anxious children preferred dentist with protective wear. Female dentists were preferred by 452 (66% anxious children. Same gender preference was also prevalent.

Childhood anxiety is associated with low levels of parental autonomy granting and child perceived control, elevated child emotional reactivity and deficits in child emotion regulation. In early childhood, low levels of parental autonomy granting are thought to decrease child perceived control, which in turn leads to increases in child negative emotion. Later in development, perceived control may become a more stable, trait-like characteristic that amplifies the relationship between parental autonomy granting and child negative emotion. The purpose of this study was to test mediation and moderation models linking parental autonomy granting and child perceived control with child emotional reactivity and emotion regulation in anxious youth. Clinically anxious youth (N = 106) and their primary caregivers were assessed prior to beginning treatment. Children were administered a structured diagnostic interview and participated in a parent-child interaction task that was behaviorally coded for parental autonomy granting. Children completed an ecological momentary assessment protocol during which they reported on perceived control, emotional reactivity (anxiety and physiological arousal) and emotion regulation strategy use in response to daily negative life events. The relationship between parental autonomy granting and both child emotional reactivity and emotion regulation strategy use was moderated by child perceived control: the highest levels of self-reported physiological responding and the lowest levels of acceptance in response to negative events occurred in children low in perceived control with parents high in autonomy granting. Evidence for a mediational model was not found. In addition, child perceived control over negative life events was related to less anxious reactivity and greater use of both problem solving and cognitive restructuring as emotion regulation strategies. Both parental autonomy granting and child perceived control play important roles in the

Dynamically tracking anxious individuals' affective response to valenced information.

Fua, Karl C; Teachman, Bethany A

2017-09-01

Past research has shown that an individual's feelings at any given moment reflect currently experienced stimuli as well as internal representations of similar past experiences. However, anxious individuals' affective reactions to streams of interrelated valenced information (vs. reactions to static stimuli that are arguably less ecologically valid) are rarely tracked. The present study provided a first examination of the newly developed Tracking Affect Ratings Over Time (TAROT) task to continuously assess anxious individuals' affective reactions to streams of information that systematically change valence. Undergraduate participants (N = 141) completed the TAROT task in which they listened to narratives containing positive, negative, and neutral physically- or socially-relevant events, and indicated how positive or negative they felt about the information they heard as each narrative unfolded. The present study provided preliminary evidence for the validity and reliability of the task. Within scenarios, participants higher (vs. lower) in anxiety showed many expected negative biases, reporting more negative mean ratings and overall summary ratings, changing their pattern of responding more quickly to negative events, and responding more negatively to neutral events. Furthermore, individuals higher (vs. lower) in anxiety tended to report more negative minimums during and after positive events, and less positive maximums after negative events. Together, findings indicate that positive events were less impactful for anxious individuals, whereas negative experiences had a particularly lasting impact on future affective responses. The TAROT task is able to efficiently capture a number of different cognitive biases, and may help clarify the mechanisms that underlie anxious individuals' biased negative processing.

Having an insecure attachment style in schizophrenia has been linked to treatment response and symptom severity in schizophrenia. This study sought to further examine whether attachment style is related to subjective indicators of recovery including hope and self-esteem, independent of symptom level and secondly, whether attachment style in schizophrenia differs from attachment style of persons facing adversity in the form of a prolonged non-psychiatric medical illness. Participants were 52 men with schizophrenia, and 26 with HIV/AIDS who had no history of experiencing severe mental illness. These groups were compared in terms of their endorsement of attachment style. All participants were administered the Experiences in Close Relationships measure of adult attachment style. The schizophrenia group was also given the Rosenberg Self-Esteem Scale to assess self-esteem, the Beck Hopelessness Scale as a measure of hope, and the Positive and Negative Syndrome Scale, as an assessment of symptoms. Avoidant attachment in the schizophrenia group was linked with higher levels of hopelessness while anxious attachment was linked to lower levels of self-esteem. The association between anxious attachment and self-esteem persisted after controlling for severity of positive, negative, and depressive symptoms in a stepwise multiple regression analyses. Compared to the HIV/AIDS group, participants with schizophrenia had significantly higher levels of anxious attachment but not avoidant attachment style. Attachment style may impact attainment of key subjective domains of recovery in schizophrenia such as self-esteem, independent of symptom severity. If self-esteem and/or hopelessness are identified as a focus of treatment, focusing on attachment style may be an important treatment component. Therapist understanding of patients' attachment style may allow for a better understanding of resistance in the therapeutic relationship. Helping persons with schizophrenia to recognize and

Anxious and egocentric: how specific emotions influence perspective taking.

People frequently feel anxious. Although prior research has extensively studied how feeling anxious shapes intrapsychic aspects of cognition, much less is known about how anxiety affects interpersonal aspects of cognition. Here, we examine the influence of incidental experiences of anxiety on perceptual and conceptual forms of perspective taking. Compared with participants experiencing other negative, high-arousal emotions (i.e., anger or disgust) or neutral feelings, anxious participants displayed greater egocentrism in their mental-state reasoning: They were more likely to describe an object using their own spatial perspective, had more difficulty resisting egocentric interference when identifying an object from others' spatial perspectives, and relied more heavily on privileged knowledge when inferring others' beliefs. Using both experimental-causal-chain and measurement-of-mediation approaches, we found that these effects were explained, in part, by uncertainty appraisal tendencies. Further supporting the role of uncertainty, a positive emotion associated with uncertainty (i.e., surprise) produced increases in egocentrism that were similar to anxiety. Collectively, the results suggest that incidentally experiencing emotions associated with uncertainty increase reliance on one's own egocentric perspective when reasoning about the mental states of others.

Schnabel, Konrad; Banse, Rainer; Asendorpf, Jens B

2006-06-01

This study explored the psychometric properties of the Implicit Association Test (IAT) when it is employed for the assessment of two personality traits within one sample. The sequence of an anxiousness and an angriness IAT was counterbalanced across 100 participants and the IATs' predictive validity for anxious versus angry behaviour after emotion inductions was examined and compared to direct self-report measures. The anxiousness IAT added incremental validity over direct measures for the prediction of anxious behaviour. The angriness IAT was affected by an order effect. When the angriness IAT was completed after the anxiousness IAT both tests correlated with r=.46 whereas they were not significantly correlated when the angriness IAT was completed first. Direct anxiousness and angriness measures were uncorrelated. Implications for the assessment of multiple implicit personality self-concept dimensions are discussed.

Socially anxious and confident men interact with a forward virtual woman: an experimental study.

Full Text Available Male volunteers entered an immersive virtual reality that depicted a party, where they were approached by a lone virtual woman who initiated a conversation. The goal was to study how socially anxious and socially confident men would react to this event. Interest focused on whether the socially anxious participants would exhibit sustained anxiety during the conversation or whether this would diminish over time, and differ from the responses of the more socially confident men.The scenario was a party with five virtual characters, four sitting at a distance from the participant and talking amongst themselves and one lone woman standing closer. The woman approached the participant, introduced herself and initiated a conversation that was first about mundane matters and then became more personal and intimate. Participants were men who were either relatively socially confident (18 or socially anxious in their relationships with women (18. A second experimental factor was whether or not the other four characters occasionally looked towards the participant. There was a post-trial questionnaire about social anxiety in relation to the experience, and skin conductance and ECG physiological measures were recorded. Our expectation was that the socially anxious participants would show greater anxiety throughout.Compared to baseline readings both socially confident and socially anxious groups on average showed signs of significantly increased stress at the initial approach of the virtual woman. The stress then diminished once the conversation entered into the mundane phase and then did not significantly change. Comparing pre- and post-questionnaire anxiety scores there was no change for the more confident participants but a significant decrease in average score amongst the anxious group.

Despite the frequent co-ocurrence of hypermobile Ehler-Danlos syndrome (hEDS) and pathological anxiety, little is known about the psychosocial and health implications of such comorbidity. Our aim was to explore the association between high levels of anxiety and psychosocial (catastrophizing, kinesiophobia, somatosensory amplification, social support and functioning), health (pain, fatigue, BMI, tobacco/alcohol use, depression, diagnosis delay, general health), and sociodemographic factors in people with hEDS. In this cross-sectional study, 80 hEDS patients were divided into two groups according to self-reported anxiety levels: low and high. Psychosocial, sociodemographic and health variables were compared between the groups. Forty-one participants reported a high level of anxiety (51.2%). No differences were found in the sociodemographic variables between high-anxious and low-anxious patients. The percentage of participants with severe fatigue and high depressive symptomatology was significantly higher in the high-anxious group (80.5 vs 56.4; 26.8 vs 12.8%, respectively). High-anxious hEDS patients also showed significantly higher levels of pain catastrophizing, somatosensory amplification as well as a poorer social functioning and general health. Multivariate analyses showed that somatosensory amplification, pain catastrophizing and poor social functioning are variables that increase the probability of belonging to the high-anxious group. Despite limitations, this first study comparing high-anxious versus low-anxious hEDS patients with respect to health aspects, highlight the importance of considering the psychosocial factors (many susceptible to modification), to improve the adjustment to this chronic condition and provide support to those affected through a biopsychosocial approach.

We have conducted a longitudinal observational study in order to evaluate the prevalence and the incidence of depressive and anxious symptoms in women and men seeking infertility treatment and to analyze associated factors or risk factors for these kinds of disorders. A total of 1000 consecutive couples that visited our center for the first time were asked to join this study. Depressive and anxious symptoms were assessed with self-rating Zung Depression Scale (ZDS) and Zung Anxiety Scale (ZAS) questionnaires. A second assessment was planned at the time of β HCG dosage (or at the moment of cycle suspension). A standard questionnaire was used to investigate socio-demographic information and the psychological aspects of couples undergoing in vitro fertilization (IVF) treatment. The fertility history and outcome of IVF treatment were collected from patients' medical records. 14.7% of women had anxious symptoms and 17.9% depressive symptoms, whereas 4.5% of men had anxious symptoms and 6.9% depressive symptoms. Women with depressive and anxious symptoms were younger, more often had an anxious partner and had a longer history of infertility. Men with depressive and anxious symptoms more frequently had a temporary job, they had an anxious partner and they were more frequently at the first in vitro fertilization (IVF) cycle. The incidence of depressive and/or anxious symptoms was 18.5% in women and 7.4% in men. Age and previous IVF treatments seem not to be associated with incidence of depressive or anxious symptoms. Both the prevalence and incidence of depressive and/or anxious symptoms in couples undergoing IVF treatment were worthy of note and should not be underestimated. More attention must be paid to psychological aspects in young women and in couples with a long history of infertility or previous failure treatments. Having an anxious partner was associated with anxious and depressive symptoms. For this reason, both males and females might benefit from psychological

Direction of attention bias to threat relates to differences in fear acquisition and extinction in anxious children.

Science.gov (United States)

Waters, Allison M; Kershaw, Rachel

2015-01-01

Anxious children show attention biases towards and away from threat stimuli. Moreover, threat avoidance compared to vigilance predicts a poorer outcome from exposure-based treatments, such as cognitive-behavioural therapy (CBT), yet the mechanisms underlying this differential response are unclear. Pavlovian fear conditioning is a widely accepted theory to explain the acquisition and extinction of fear, including exposure-based treatments, such as CBT. In typical fear conditioning experiments, anxious children have shown larger physiological responses to an aversive unconditional stimulus (i.e., US on CS+ trials) and to non-reinforced stimuli (CS-) during fear acquisition and to both CSs during fear extinction compared to non-anxious peers. This study examined whether threat avoidance compared to threat vigilance was related to differences in fear acquisition and extinction in anxious children. Thirty-four clinically-anxious children completed a visual probe task including angry-neutral face pairs to determine the direction of threat attention bias as well as a discriminant conditioning and extinction task in which a geometric shape CS+ was paired with an aversive tone US, while the CS- geometric shape was always presented alone during acquisition trials. Both CSs were presented alone during extinction trials. Fear acquisition and extinction were indexed by skin conductance responses (SCR) and subjective measures. Children were classified as threat vigilant (N = 18) and threat avoidant (n = 16) based on the direction of threat attention bias on the visual probe task. During acquisition, threat avoidant relative to threat vigilant anxious children displayed larger orienting SCRs to both CSs during the first block of trials and larger third interval SCRs to the US on CS+ trials as well as on CS- trials. During extinction, threat avoidant anxious children showed delayed extinction of SCRs to both the CS+ and CS- and reported higher subjective anxiety ratings after

Delirium can be conceptualized as an acute decline in cognitive function that typically lasts from hours to a few days. Prolonged delirium can also affect patients with multiple predisposing and/or precipitating factors. In clinical practice, prolonged delirium is often unrecognized, and can be misdiagnosed as other psychiatric disorders. We describe a case of a 59-year-old male presenting with behavioral and cognitive symptoms that was first misdiagnosed as a mood disorder in a general hospital setting. After prolonged delirium due to multiple factors was confirmed, the patient was treated accordingly with symptomatic management. He evolved with progressive improvement of his clinical status. Early diagnosis and management of prolonged delirium are important to improve patient prognosis and avoid iatrogenic measures.

We conducted a 3-wave, longitudinal study to examine the role of ethnic collective self-esteem and United States (U.S.) collective self-esteem on anxious-depressed symptoms over time among Asian and Latino immigrant-origin adolescents (n = 171). Growth curve analysis revealed that anxious-depressed symptoms first decreased between 10th and 11th grade and then increased over time for both groups. Additionally higher levels of ethnic collective self-esteem were associated with lower levels of anxious-depressed symptoms only for Asian adolescents. There was a differing pattern for U.S. collective self-esteem such that for Latino adolescents, higher U.S. collective self-esteem was associated with higher anxious-depressed symptoms, whereas for Asian adolescents there was an inverse relationship with anxious-depressed symptoms. The results expand the literature on ethnic and U.S. collective self-esteem and their link to mental health. Implications of the findings for research in general, and for counseling immigrant youth and families in particular, are discussed.

Anxiety disorders are prevalent among adolescents and may have long-lasting negative consequences for the individual, the family and society. Cognitive behavioral therapy (CBT) is an effective treatment. However, many anxious youth do not seek treatment. Low-intensity CBT in schools may improve access to evidence-based services. We aim to investigate the efficacy of two CBT youth anxiety programs with different intensities (i.e., number and length of sessions), both group-based and administered as early interventions in a school setting. The objectives of the study are to examine the effects of school-based interventions for youth anxiety and to determine whether a less intensive intervention is non-inferior to a more intensive intervention. The present study is a randomized controlled trial comparing two CBT interventions to a waitlist control group. A total of 18 schools participate and we aim to recruit 323 adolescents (12-16 years). Youth who score above a cutoff on an anxiety symptom scale will be included in the study. School nurses recruit participants and deliver the interventions, with mental health workers as co-therapists and/or supervisors. Primary outcomes are level of anxiety symptoms and anxiety-related functional impairments. Secondary outcomes are level of depressive symptoms, quality of life and general psychosocial functioning. Non-inferiority between the two active interventions will be declared if a difference of 1.4 or less is found on the anxiety symptom measure post-intervention and a difference of 0.8 on the interference scale. Effects will be analyzed by mixed effect models, applying an intention to treat procedure. The present study extends previous research by comparing two programs with different intensity. A brief intervention, if effective, could more easily be subject to large-scale implementation in school health services. ClinicalTrials.gov, NCT02279251 . Registered on 15 October 2014.

Background Neuroimaging research has traditionally explored fear and anxiety in response to discrete threat cues (e.g., during fear conditioning). However, anxiety is a sustained aversive state that can persist in the absence of discrete threats. Little is known about mechanisms that maintain anxiety states over a prolonged period. Here, we used a robust translational paradigm (threat of shock) to induce sustained anxiety. Recent translational work has implicated an amygdala–prefrontal cortex (PFC) circuit in the maintenance of anxiety in rodents. To explore the functional homologues of this circuitry in humans, we used a novel paradigm to examine the impact of sustained anticipatory anxiety on amygdala–PFC intrinsic connectivity. Methods Task-independent fMRI data were collected in healthy participants during long-duration periods of shock anticipation and safety. We examined intrinsic functional connectivity. Results Our study involved 20 healthy participants. During sustained anxiety, amygdala activity was positively coupled with dorsomedial PFC (DMPFC) activity. High trait anxiety was associated with increased amygdala–DMPFC coupling. In addition, induced anxiety was associated with positive coupling between regions involved in defensive responding, and decreased coupling between regions involved in emotional control and the default mode network. Limitations Inferences regarding anxious pathology should be made with caution because this study was conducted in healthy participants. Conclusion Findings suggest that anticipatory anxiety increases intrinsic amygdala–DMPFC coupling and that the DMPFC may serve as a functional homologue for the rodent prefrontal regions by sustaining anxiety. Future research may use this defensive neural context to identify bio-markers of risk for anxious pathology and target these circuits for therapeutic intervention. PMID:24886788

We examined the association between the Hamilton Depression Scale (HAMD) approach to classifying depressed patients into anxious and nonanxious subgroups and the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) anxious distress specifier subtyping. Two hundred two depressed patients were interviewed with semistructured diagnostic interviews. Patients were rated on the 17-item HAMD and the Hamilton Anxiety Rating Scale and completed the Clinically Useful Anxiety Outcome Scale. Both approaches toward identifying anxiety in depressed patients resulted in most of the patients meeting the anxiety subtype. Both subtyping methods were significantly correlated with clinician-rated and self-report measures of anxiety, and scores on the anxiety scales were higher in the patients who met the anxious subtype. However, DSM-5 anxious distress subtyping was only marginally associated with the HAMD anxiety/somatization factor subtyping approach (k = 0.21), and dimensional scores were only moderately correlated (r = 0.50). These findings indicate that the DSM-5 and HAMD approaches toward identifying an anxious subtype of depression are not interchangeable.

The goal of the current study was to examine the complex links among anxious solitude, classroom climate, engagement, achievement, and gender. In particular, drawing upon the differential susceptibility hypothesis (Belsky, 1997), we investigated if children high in anxious solitude were particularly sensitive and responsive to the classroom environment. Participants were N = 712 children in Grade 3, drawn from the National Institute of Child and Human Development (NICHD) Study of Early Child Care and Youth Development data set. Classroom climate and engagement were assessed using the Classroom Observation Scale (NICHD, 1998). Teachers completed the Teacher Report Form (Achenbach, 1991) as a measure of anxious solitude and the Academic Rating Scale (NICHD, 2010) as a measure of achievement. Hypothesized associations among variables were tested by way of a moderated-mediation model. Among the results, engagement was found to mediate the relation between classroom climate and achievement. In addition, anxious solitude and gender were found to moderate the relation between classroom climate and engagement. Support for the differential susceptibility hypothesis was found, suggesting that children high in anxious solitude may be more reactive (both positively and negatively) to elements of the classroom environment. In addition, gender differences were observed, indicating that boys may be more responsive to the classroom environment as compared with girls. Implications for future research and educational policies are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Anxious and angry rejection sensitivity, social withdrawal, and retribution in high and low ambiguous situations.

Zimmer-Gembeck, Melanie J; Nesdale, Drew

2013-02-01

Rejection sensitivity (RS) is a tendency to expect, perceive, and overreact to rejection. Our objective was to examine whether anxious and angry RS have specific associations with negative social reactions, and whether responses are intensified in situations of high rejection ambiguity. In two studies, youth (N = 464 and N = 371) reported their RS and anticipated responses to social scenarios. In Study 1, all scenarios portrayed overt rejection events. In Study 2, participants were randomly assigned to conditions portraying overt or ambiguous rejection. Greater rejection expectation was associated with more negative reactions to rejection. Moreover, as expected, anxiety about rejection was uniquely associated with withdrawal, and anger about rejection was uniquely associated with retribution (i.e., reactive aggression). In the second study, RS persons responded more negatively than others to both overt and high ambiguous rejections, but retribution was intensified among participants high in rejection expectation when rejection was ambiguous, and withdrawal was intensified among participants high in anxious RS in overt rejection situations. Consistent with the revised RS model, there are different patterns of emotions, cognitions, and behaviors in response to high and low ambiguous rejection events, which are heightened in youth sensitive to rejection. © 2012, Wiley Periodicals, Inc.

This study examined separate developmental trajectories of anxious and depressive symptoms from childhood to adolescence (9-15 years) in a community-based sample (N = 290). At three measurement points, mothers and fathers reported on their children's anxious and depressive symptoms, and at Time 1 they reported on lower order child personality facets and on their parenting. By means of growth mixture modeling, three developmental trajectories were identified for anxious symptoms: steady low (82%), moderate increasing-decreasing (5.9%), and high declining groups (12.1%). For depressive symptoms, two developmental trajectories were found: steady low (94.1%) and moderate increasing groups (5.9%). Higher shyness, irritability, and altruism predicted membership in more problematic anxious and depressive groups. The personality facets energy, optimism, compliance, and anxiety were unique predictors for class membership for anxious symptoms, and the effects of shyness, irritability, and compliance were moderated by overreactive parenting. Shyness and irritability increased the probability of following the moderate increasing-decreasing anxiety trajectory, but only in the context of high or average levels of overreactive parenting. Compliance increased the probability of following the moderate increasing-decreasing and high decreasing trajectories in the context of high overreactive parenting. Our results indicate that childhood personality facets differentiate trajectories of anxious and depressive symptoms in theoretically compelling ways.

Excessive sitting behavior is a risk factor for many adverse health outcomes. This study aimed to survey the prevalence of sitting behavior and its adverse effects among Iranian office workers. This cross-sectional study included 447 Iranian office workers. A two-part questionnaire was used as the data collection tool. The first part surveyed the demographic characteristics and general health of the respondents, while the second part contained the Nordic Musculoskeletal Questionnaire (NMQ) to assess symptoms. Statistical analyses were performed using the Statistical Package for the Social Sciences software using Mann-Whitney U and Chi-square tests and multiple logistic regression analysis. The respondents spent an average of 6.29 hours of an 8-hour working shift in a sitting position. The results showed that 48.8% of the participants did not feel comfortable with their workstations and 73.6% felt exhausted during the workday. Additionally, 6.3% suffered from hypertension, and 11.2% of them reported hyperlipidemia. The results of the NMQ showed that neck (53.5%), lower back (53.2%) and shoulder (51.6%) symptoms were the most prevalent problem among office workers. Based upon a multiple logistic regression, only sex had a significant association with prolonged sitting behavior (odds ratio = 3.084). Our results indicated that long sitting times were associated with exhaustion during the working day, decreased job satisfaction, hypertension, and musculoskeletal disorder symptoms in the shoulders, lower back, thighs, and knees of office workers. Sitting behavior had adverse effects on office workers. Active workstations are therefore recommended to improve working conditions.

2018-01-01

Larger distance effects in high math-anxious individuals (HMA) performing comparison tasks have previously been interpreted as indicating less precise magnitude representation in this population. A recent study by Dietrich, Huber, Moeller, and Klein limited the effects of math anxiety to symbolic comparison, in which they found larger distance effects for HMA, despite equivalent size effects. However, the question of whether distance effects in symbolic comparison reflect the properties of the magnitude representation or decisional processes is currently under debate. This study was designed to further explore the relation between math anxiety and magnitude representation through three different tasks. HMA and low math-anxious individuals (LMA) performed a non-symbolic comparison, in which no group differences were found. Furthermore, we did not replicate previous findings in an Arabic digit comparison, in which HMA individuals showed equivalent distance effects to their LMA peers. Lastly, there were no group differences in a counting Stroop task. Altogether, an explanation of math anxiety differences in terms of less precise magnitude representation is not supported.

Attentional bias toward threatening or emotional information is considered a cognitive marker of anxiety, and it has been described in various clinical and subclinical populations. This study used an emotional Stroop task to investigate whether math anxiety is characterized by an attentional bias toward math-related words. Two previous studies failed to observe such an effect in math-anxious individuals, although the authors acknowledged certain methodological limitations that the present study seeks to avoid. Twenty high math-anxious (HMA) and 20 low math-anxious (LMA) individuals were presented with an emotional Stroop task including math-related and neutral words. Participants in the two groups did not differ in trait anxiety or depression. We found that the HMA group showed slower response times to math-related words than to neutral words, as well as a greater attentional bias (math-related – neutral difference score) than the LMA one, which constitutes the first demonstration of an attentional bias toward math-related words in HMA individuals.

Ellenbogen, Mark A; Schwartzman, Alex E

2009-02-01

Although it is well established that attentional biases exist in anxious populations, the specific components of visual orienting towards and away from emotional stimuli are not well delineated. The present study was designed to examine these processes. We used a modified spatial cueing task to assess the speed of engagement and disengagement from supraliminal and masked pictorial cues depicting threat, dysphoria, or neutral content in 36 clinically anxious, 41 depressed and 41 control participants. Participants were randomly assigned to a stress or neutral condition. During stress, anxious participants were slow to disengage from masked left hemifield pictures depicting threat or dysphoria, but were quick to disengage from supraliminal threat pictures. Information processing in anxious participants during stress was characterized by early selective attention of emotional stimuli, occurring prior to full conscious awareness, followed by effortful avoidance of threat. Depressed participants were distinct from the anxious group, displaying selective attention for stimuli depicting dysphoria, but not threat, during the neutral condition. In sum, attentional biases in clinical populations are associated with difficulties in the disengagement component of visual orienting. Further, a vigilant-avoidant pattern of attentional bias may represent a strategic attempt to compensate for the early activation of a fear response.

AIMS To examine cross-national patterns and correlates of lifetime and 12-month comorbid DSM-IV anxiety disorders among people with lifetime and 12-month DSM-IV major depressive disorder (MDD). METHODS Nationally or regionally representative epidemiological interviews were administered to 74,045 adults in 27 surveys across 24 countries in the WHO World Mental Health (WMH) Surveys. DSM-IV MDD, a wide range of comorbid DSM-IV anxiety disorders, and a number of correlates were assessed with the WHO Composite International Diagnostic Interview (CIDI). RESULTS 45.7% of respondents with lifetime MDD (32.0–46.5% inter-quartile range [IQR] across surveys) had one of more lifetime anxiety disorders. A slightly higher proportion of respondents with 12-month MDD had lifetime anxiety disorders (51.7%, 37.8–54.0% IQR) and only slightly lower proportions of respondents with 12-month MDD had 12-month anxiety disorders (41.6%, 29.9–47.2% IQR). Two-thirds (68%) of respondents with lifetime comorbid anxiety disorders and MDD reported an earlier age-of-onset of their first anxiety disorder than their MDD, while 13.5% reported an earlier age-of-onset of MDD and the remaining 18.5% reported the same age-of-onset of both disorders. Women and previously married people had consistently elevated rates of lifetime and 12-month MDD as well as comorbid anxiety disorders. Consistently higher proportions of respondents with 12-month anxious than non-anxious MDD reported severe role impairment (64.4% vs. 46.0%; χ21=187.0, pdepression in the 12 months before interview, but this difference was more pronounced in high income countries (68.8% vs. 45.4%; χ21=108.8, p<.001) than low/middle income countries (30.3% vs. 20.6%; χ21=11.7, p<.001). CONCLUSIONS Patterns and correlates of comorbid DSM-IV anxiety disorders among people with DSM-IV MDD are similar across WMH countries.

2017-08-18

Dispositional anxiety is a trait-like phenotype that confers increased risk for a range of debilitating neuropsychiatric disorders. Like many patients with anxiety disorders, individuals with elevated levels of dispositional anxiety are prone to intrusive and distressing thoughts in the absence of immediate threat. Recent electrophysiological research suggests that these symptoms are rooted in the mis-allocation of working memory (WM) resources to threat-related information. Here, functional MRI was used to identify the network of brain regions that support WM for faces and to quantify the allocation of neural resources to threat-related distracters in 81 young adults. Results revealed widespread evidence of mis-allocation. This was evident in both face-selective regions of the fusiform cortex and domain-general regions of the prefrontal and parietal cortices. This bias was exaggerated among individuals with a more anxious disposition. Mediation analyses provided compelling evidence that anxious individuals' tendency to mis-allocate WM resources to threat-related distracters is statistically explained by heightened amygdala reactivity. Collectively, these results provide a neurocognitive framework for understanding the pathways linking anxious phenotypes to the development of internalizing psychopathology and set the stage for developing improved intervention strategies.

Structural connectomics of anxious arousal in early adolescence: Translating clinical and ethological findings

Directory of Open Access Journals (Sweden)

Paul B. Sharp

2017-01-01

Full Text Available Etiological explanations of clinical anxiety can be advanced through understanding the neural mechanisms associated with anxiety in youth prior to the emergence of psychopathology. In this vein, the present study sought to investigate how trait anxiety is related to features of the structural connectome in early adolescence. 40 adolescents (21 female, mean age = 13.49 years underwent a diffusion-weighted imaging scan. We hypothesized that the strength of several a priori defined structural connections would vary with anxious arousal based on previous work in human clinical neuroscience and adult rodent optogenetics. First, connection strength of caudate to rostral middle frontal gyrus was predicted to be anticorrelated with anxious arousal, predicated on extant work in clinically-diagnosed adolescents. Second, connection strength of amygdala to rostral anterior cingulate and to medial orbital frontal cortex would be positively and negatively correlated with anxious arousal, respectively, predicated on rodent optogenetics showing the former pathway is anxiogenic and the latter is anxiolytic. We also predicted that levels of anxiety would not vary with measures of global network topology, based on reported null findings. Results support that anxiety in early adolescence is associated with (1 the clinical biomarker connecting caudate to frontal cortex, and (2 the anxiogenic pathway connecting amygdala to rostral anterior cingulate, both in left but not right hemisphere. Findings support that in early adolescence, anxious arousal may be related to mechanisms that increase anxiogenesis, and not in a deficit in regulatory mechanisms that support anxiolysis.

Episodic rage represents an important and underappreciated clinical feature in pediatric anxiety. This study examined the incidence and clinical correlates of rage in children with anxiety disorders. Change in rage during treatment for anxiety was also examined. Participants consisted of 107 children diagnosed with an anxiety disorder and their parents. Participants completed structured clinical interviews and questionnaire measures to assess rage, anxiety, functional impairment, family accommodation and caregiver strain, as well as the quality of the child's relationship with family and peers. Rage was a common feature amongst children with anxiety disorders. Rage was associated with a more severe clinical profile, including increased anxiety severity, functional impairment, family accommodation and caregiver strain, as well as poorer relationships with parents, siblings, extended family and peers. Rage was more common in children with separation anxiety, comorbid anxiety, attention deficit/hyperactivity disorder and behavioral disorders, but not depressive symptoms. Rage predicted higher levels of functional impairment, beyond the effect of anxiety severity. Rage severity reduced over treatment in line with changes in anxiety symptoms. Findings suggest that rage is a marker of greater psychopathology in anxious youth. Standard cognitive behavioral treatment for anxiety appears to reduce rage without adjunctive treatment.

2009-01-01

Full Text Available Abstract Background Anxiety and depression are common and treatable risk factors for re-hospitalisation and death in patients with COPD. The degree of lung function impairment does not sufficiently explain anxiety and depression. The BODE index allows a functional classification of COPD beyond FEV1. The aim of this cross-sectional study was (1 to test whether the BODE index is superior to the GOLD classification for explaining anxious and depressive symptoms; and (2 to assess which components of the BODE index are associated with these psychological aspects of COPD. Methods COPD was classified according to the GOLD stages based on FEV1%predicted in 122 stable patients with COPD. An additional four stage classification was constructed based on the quartiles of the BODE index. The hospital anxiety and depression scale was used to assess anxious and depressive symptoms. Results The overall prevalence of anxious and depressive symptoms was 49% and 52%, respectively. The prevalence of anxious symptoms increased with increasing BODE stages but not with increasing GOLD stages. The prevalence of depressive symptoms increased with both increasing GOLD and BODE stages. The BODE index was superior to FEV1%predicted for explaining anxious and depressive symptoms. Anxious symptoms were explained by dyspnoea. Depressive symptoms were explained by both dyspnoea and reduced exercise capacity. Conclusion The BODE index is superior to the GOLD classification for explaining anxious and depressive symptoms in COPD patients. These psychological consequences of the disease may play a role in future classification systems of COPD.

2017-08-01

Developmental models of pediatric anxiety posit multiple, maladaptive parenting behaviors as potential risk factors. Despite this, a standardized means of assessing multiple of these practices (i.e., anxiogenic parenting) in a comprehensive and efficient manner are lacking. In Study 1531 parents of children 7-17 years old completed an online survey via Amazon Mechanical Turk. In Study 2, a separate community sample (N = 109; 9-17 years old) was recruited and completed a comprehensive assessment battery as part of a larger study. All parents (Study 1 and 2 samples) completed the Parenting Anxious Kids Ratings Scale-Parent Report (PAKRS-PR), a measurement tool designed to assess anxiogenic parenting. Factor analysis conducted as part of Study 1 revealed a 32-item scale consisting of five factors: conflict, overinvolvement, accommodation/beliefs, modeling, and emotional warmth/support. Four of these factors were significantly correlated with parent-report of anxiety severity. Within Study 2, the parents of children diagnosed with an anxiety or related disorder reported significantly higher levels of anxiogenic parenting practices as compared to the parents of healthy controls. The PAKRS-PR and respective subscales demonstrated acceptable reliability and validity in both the internet (Study 1) and community (Study 2) samples. The PAKRS-PR may be a beneficial multidimensional parenting scale for use among anxious youths.

Socially anxious individuals are interfered by distractors. Recent work has suggested that low working memory capacity and inappropriate temporary goal induce attention to distractors. We investigated the effects of working memory capacity and temporary goal on attention to distractors in social anxiety. Participants viewed a rapid serial visual presentation, in which participants reported the identity of a single target letter drawn in red. Distractors appeared before the target was presented. When the color of distractors was red (i.e., goal-relevant stimuli), low-capacity individuals were strongly interfered by the distractors compared to high-capacity individuals regardless of social anxiety. When the color of distractors was goal-irrelevant, low-capacity and high socially anxious individuals were strongly interfered by the distractors. These results suggest that socially anxious individuals with low working memory capacity could not inhibit the goal-irrelevant information and direct attention to distractors.

Difficulties in coping with cancer, and the accompanying anxious and depressive symptoms, have been shown to affect the mood and the quality of life in breast cancer patients. 5-Hydroxytryptamine Transporter Gene-linked Polymorphic Region (5-HTTLPR) functional polymorphism of serotonin transporter has been shown to influence the adaptation to stressful life events. The aim of this prospective study was therefore to examine the association of 5-HTTLPR with the mental adaptation to cancer diagnosis and treatment. Forty eight consecutive patients with early mammary carcinoma were evaluated at enrolment and at follow up after one and three months. The patients were characterized psychometrically using the Hospital Anxiety and Depression Scale (HADS) and the Mini-Mental Adjustment to Cancer Scale (Mini-MAC); 5-HTTLPR allelic variants were determined using PCR-based techniques. In women with early breast cancer, the mental adaptation to the disease was associated with high scores of avoidance and anxious preoccupation of Mini-MAC, which decreased with time at follow up. Anxious preoccupation decreased with time less in patients with the S/S and S/L genetic variant of 5-HTTLPR as compared with the L/L carriers (p=0.023), indicating gene - environment interactions. These results indicate that the characterization of 5-HTTLPR allows the identification of breast cancer patients in greater risk of mental suffering, for which specific intervention may be focused; in case of drug therapy, they provide indications for the choice of most appropriate agent in a pharmacogenetic perspective

Early maladaptive schemas and social anxiety in adolescents: the mediating role of anxious automatic thoughts.

Cognitive models state that cognitions are organized hierarchically, so that the underlying schemas affect behavior via more automatic, superficial cognitive processes. This study aimed to demonstrate that early maladaptive schemas predict anxious automatic thoughts, and to show that such automatic thoughts act as mediators between schemas and prospective changes in social anxiety symptoms. The study also examined an alternative reverse model in which schemas acted as mediators between automatic thoughts and social anxiety. A total of 1052 adolescents (499 girls and 553 boys; M(age)=13.43; SD(age)=1.29) completed measures of early maladaptive schemas, socially anxious automatic thoughts, and social anxiety symptoms at Times 1, 2, and 3. The results revealed bidirectional longitudinal relationships among schemas and automatic thoughts that were consistent in content (e.g., the disconnection/rejection schemas and automatic thoughts of negative self-concept). Furthermore, the automatic thoughts of anticipatory negative evaluation by others at Time 2 mediated the relationship between the other-directedness schemas at Time 1 and social anxiety symptoms at Time 3. These findings are consistent with hierarchical cognitive models of social anxiety given that deeper schemas predict more surface-level thoughts. They also support that these more surface-level thoughts contribute to perpetuating schemas. Finally, results show that early maladaptive schemas of the other-directedness domain play a relevant role in the development and maintenance of social anxiety. Copyright © 2013 Elsevier Ltd.

Less is more: prolonged intermittent access cocaine self-administration produces incentive-sensitization and addiction-like behavior.

Kawa, Alex B; Bentzley, Brandon S; Robinson, Terry E

Contemporary animal models of cocaine addiction focus on increasing the amount of drug consumption to produce addiction-like behavior. However, another critical factor is the temporal pattern of consumption, which in humans is characterized by intermittency, both within and between bouts of use. To model this, we combined prolonged access to cocaine (∼70 days in total) with an intermittent access (IntA) self-administration procedure and used behavioral economic indicators to quantify changes in motivation for cocaine. IntA produced escalation of intake, a progressive increase in cocaine demand (incentive-sensitization), and robust drug- and cue-induced reinstatement of drug-seeking behavior. We also asked whether rats that vary in their propensity to attribute incentive salience to reward cues (sign-trackers [STs] vs. goal-trackers [GTs]) vary in the development of addiction-like behavior. Although STs were more motivated to take cocaine after limited drug experience, after IntA, STs and GTs no longer differed on any measure of addiction-like behavior. Exposure to large quantities of cocaine is not necessary for escalation of intake, incentive-sensitization, or other addiction-like behaviors (IntA results in far less total cocaine consumption than 'long access' procedures). Also, the ST phenotype may increase susceptibility to addiction, not because STs are inherently susceptible to incentive-sensitization (perhaps all individuals are at risk), but because this phenotype promotes continued drug use, subjecting them to incentive-sensitization. Thus, the pharmacokinetics associated with the IntA procedure are especially effective in producing a number of addiction-like behaviors and may be valuable for studying associated neuroadaptations and for assessing individual variation in vulnerability.

Persons suffering from anxiety disorders display facilitated processing of arousing and negative stimuli, such as negative words. This memory bias is reflected in better recall and increased amygdala activity in response to such stimuli. However, individual learning histories were not considered in most studies, a concern that we meet here. Thirty-four female persons (half with high-, half with low trait anxiety) participated in a criterion-based associative word-learning paradigm, in which neutral pseudowords were paired with aversive or neutral pictures, which should lead to a valence change for the negatively paired pseudowords. After learning, pseudowords were tested with fMRI to investigate differential brain activation of the amygdala evoked by the newly acquired valence. Explicit and implicit memory was assessed directly after training and in three follow-ups at 4-day intervals. The behavioral results demonstrate that associative word-learning leads to an explicit (but no implicit) memory bias for negatively linked pseudowords, relative to neutral ones, which confirms earlier studies. Bilateral amygdala activation underlines the behavioral effect: Higher trait anxiety is correlated with stronger amygdala activation for negatively linked pseudowords than for neutrally linked ones. Most interestingly, this effect is also present for negatively paired pseudowords that participants could not remember well. Moreover, neutrally paired pseudowords evoked higher amygdala reactivity than completely novel ones in highly anxious persons, which can be taken as evidence for generalization. These findings demonstrate that few word-learning trials generate a memory bias for emotional stimuli, indexed both behaviorally and neurophysiologically. Importantly, the typical memory bias for emotional stimuli and the generalization to neutral ones is larger in high anxious persons.

Meyer, Alexandria; Gawlowska, Magda

2017-10-01

A previous study suggests that when participants were punished with a loud noise after committing errors, the error-related negativity (ERN) was enhanced in high trait anxious individuals. The current study sought to extend these findings by examining the ERN in conditions when punishment was related and unrelated to error commission as a function of individual differences in trait anxiety symptoms; further, the current study utilized an electric shock as an aversive unconditioned stimulus. Results confirmed that the ERN was increased when errors were punished among high trait anxious individuals compared to low anxious individuals; this effect was not observed when punishment was unrelated to errors. Findings suggest that the threat-value of errors may underlie the association between certain anxious traits and punishment-related increases in the ERN. Copyright © 2017 Elsevier B.V.

Trait anxiety, a stable personality trait associated with increased fear responses to threat, is regarded as a risk factor for the development and maintenance of anxiety disorders. Although the effect of trait anxiety has been examined with regard to explicit threat cues, little is known about the effect of trait anxiety on contextual threat learning. To assess this issue, extreme groups of low and high trait anxiety underwent a contextual fear conditioning protocol using virtual reality. Two virtual office rooms served as the conditioned contexts. One virtual office room (CXT+) was paired with unpredictable electrical stimuli. In the other virtual office room, no electrical stimuli were delivered (CXT−). High-anxious participants tended to show faster acquisition of startle potentiation in the CXT+ versus the CXT− than low-anxious participants. This enhanced contextual fear learning might function as a risk factor for anxiety disorders that are characterized by sustained anxiety. PMID:23384512

Fatal Attractions: Attachment to Smartphones Predicts Anthropomorphic Beliefs and Dangerous Behaviors.

Bodford, Jessica E; Kwan, Virginia S Y; Sobota, David S

2017-05-01

As technology's presence grows increasingly concrete in global societies, so too do our relationships with the devices we keep close at hand from day to day. Whereas research has, in the past, framed smartphone addiction in terms of possessional attachment, the present research hypothesizes that anxious smartphone attachment stems from human attachment, in which Anxiously attached individuals may be more likely to generalize their anxious attachment style to communication devices. In the present study, we found support for this hypothesis and showed that anxious smartphone attachment predicts (1) anthropomorphic beliefs, (2) reliance on-or "clinginess" toward-smartphones, and (3) a seemingly compulsive urge to answer one's phone, even in dangerous situations (e.g., while driving). Taken together, we seek to provide a theoretical framework and methodological tools to identify the sources of technology attachment and those most at risk of engaging in dangerous or inappropriate behaviors as a result of attachment to ever-present mobile devices.

Although research indicates that anxious arousal in response to feared stimuli is related to treatment outcome (Heimberg et al., 1990), less is known about the patterns of anxious arousal. We identified patterns of anxious arousal in individuals with social anxiety disorder (SAD) at pre- (n= 61) and posttreatment (n= 40; 12-session CBGT, Heimberg & Becker, 2002), and in non-anxious controls (NACs; n= 31) using an assessment speech task administered at pretreatment (SAD) or the pretreatment equivalent (NACs), as well as at posttreatment (SAD only). We identified nine patterns of anxious arousal across groups that we further clustered into three groups: fear habituation, fear plateau, and fear increase. Chi-square and adjusted standardized residual analyses revealed that individuals in the pretreatment SAD group displayed the fear habituation patterns significantly more than chance and the fear plateau patterns significantly less than chance. In contrast, NACs displayed the fear plateau patterns significantly more than chance and the fear habituation patterns significantly less than chance. At posttreatment, treatment non-responders displayed fear habituation patterns significantly more than chance, whereas treatment responders displayed the fear habituation patterns significantly less than chance. Findings indicate that fear habituation during an anxiety-provoking assessment task is not necessary for treatment response. Copyright © 2017. Published by Elsevier Ltd.

[Profile of social problem solving and coping profile in anxious and depressed Chileans].

Kramp, Uwe

2012-11-01

According to the Pan American Health Organization and the World Health Organization, in 2020, depression will become the second cause of disability worldwide. In Chile, anxiety and depressive disorders account for almost 28% of the total years of healthy life lost due to illness. This research seeks to explore a profile of social problem solving and coping present in people who suffer from anxious and depressive symptoms. The sample consisted of 1179 analogous Chilean participants (55.9% women), with a mean of 22.23 years (range between 18-48 years). The results suggest statistically significant differences for all social problem solving and coping strategies evaluated. Thus, if anxious or depressive symptoms increase, social problem solving or coping strategies become less adaptive.

Little is known about the sexual functioning and behavior of men anxious about the size of their penis and the means that they might use to try to alter the size of their penis. To compare sexual functioning and behavior in men with body dysmorphic disorder (BDD) concerning penis size and in men with small penis anxiety (SPA without BDD) and in a control group of men who do not have any concerns. An opportunistic sample of 90 men from the community were recruited and divided into three groups: BDD (n = 26); SPA (n = 31) and controls (n = 33). The Index of Erectile Function (IEF), sexual identity and history; and interventions to alter the size of their penis. Men with BDD compared with controls had reduced erectile dysfunction, orgasmic function, intercourse satisfaction and overall satisfaction on the IEF. Men with SPA compared with controls had reduced intercourse satisfaction. There were no differences in sexual desire, the frequency of intercourse or masturbation across any of the three groups. Men with BDD and SPA were more likely than the controls to attempt to alter the shape or size of their penis (for example jelqing, vacuum pumps or stretching devices) with poor reported success. Men with BDD are more likely to have erectile dysfunction and less satisfaction with intercourse than controls but maintain their libido. Further research is required to develop and evaluate a psychological intervention for such men with adequate outcome measures.

Exploring the Role of Neuroticism and Insecure Attachment in Health Anxiety, Safety-Seeking Behavior Engagement, and Medical Services Utilization

Directory of Open Access Journals (Sweden)

Fotios Anagnostopoulos

2016-06-01

Full Text Available The purpose of this study was to explore an extended interpersonal model of health anxiety, according to which health-anxious individuals are trapped in a vicious circle of health-related reassurance-seeking, alienation from others, and worry about health, while somatic absorption with body sensations, insecure attachment, neuroticism, safety-seeking behaviors, and medical services utilization were also included in the model. Data were collected from 196 Greek university students using standardized instruments. Results indicated that anxious attachment was directly related to absorption (β = .163, p < .05 and alienation (β = .204, p < .05, while avoidant attachment was directly related to absorption (β = −.344, p < .001, reassurance-seeking (β = −.130, p < .05, and alienation (β = .148, p < .05. Neuroticism was positively and significantly associated with all dimensions of health anxiety. Absorption, alienation, and anxious attachment were related to medical services utilization, which, in turn, was related to safety-seeking behaviors (β = .200, p < .01. Neuroticism and anxious attachment were also indirectly and positively associated with worry. Moreover, absorption was positively related to worry and reassurance-seeking, worry was positively related to reassurance-seeking, and alienation was positively related to worry. Study results highlight the key role that interpersonal (e.g., alienation from others and perceptual factors (e.g., the tendency to focus on bodily sensations can play in health anxiety maintenance, and the importance of anxious and avoidant attachment in safety-seeking behavior engagement. Implications of the results and suggestions for future research and practice are outlined.

Desensitization to media violence: links with habitual media violence exposure, aggressive cognitions, and aggressive behavior.

2011-04-01

This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content.

Horton, Karissa D; Ellison, Christopher G; Loukas, Alexandra; Downey, Darcy L; Barrett, Jennifer B

2012-06-01

Drawing on insights from attachment theory, this study examined whether three types of attachment to God--secure, avoidant, and anxious--were associated with health-risk behaviors, over and above the effects of religious attendance, peer support, and demographic covariates, in a sample of 328 undergraduate college students. Contrary to prior theory, secure attachment to God is not inversely associated with recent alcohol or marijuana use, or substance use prior to last sexual intercourse. Instead, avoidant and anxious attachment to God are associated with higher levels of drinking; anxious attachment to God is associated with marijuana use; and avoidant attachment to God is associated with substance use prior to last sexual intercourse. These patterns are gender-specific; problematic attachment to God is linked with negative outcomes solely among men.

Parent-reported suicidal behavior and correlates among adolescents in China.

2008-01-01

Suicidal risk begins to increase during adolescence and is associated with multiple biological, psychological, social, and cultural factors. This study examined the prevalence and psychosocial factors of parent-reported suicidal behavior in Chinese adolescents. A community sample of 1920 adolescents in China participated in an epidemiological study. Parents completed a structured questionnaire including child suicidal behavior, illness history, mental health problems, family history, parenting, and family environment. Multiple logistic regression was used for data analysis. Overall, 2.4% of the sample talked about suicide in the previous 6 months, 3.2% had deliberately hurt themselves or attempted suicide, and 5.1% had either suicidal talk or self-harm. The rate of suicidal behavior increased as adolescents aged. Multivariate logistic regression indicated that the following factors were significantly associated with elevated risk for suicidal behavior: depressive/anxious symptoms, poor maternal health, family conflict, and physical punishment of parental discipline style. Suicidal behavior was reported by parents. No causal relationships could be made based on cross-sectional data. The prevalence rate of parent-reported suicidal behavior is markedly lower than self-reported rate in previous research. Depressive/anxious symptoms and multiple family environmental factors are associated with suicidal behavior in Chinese adolescents.

1980-02-01

Awareness of pulse rate was tested in 60 psychiatric out-patients with anxiety, phobic or hypochondriacal neuroses by asking them to record how fast their hearts were beating during exposure to short film sequences. Correlations between subjective and objective heart rate (ECG) were significantly higher in anxious and hypochondriacal patients than in phobic ones. The results suggest that somatic symptoms in hypochondriacal and anxiety neurosis reflect increased awareness of bodily function.

Sedentary behavior, particularly in prolonged periods, is an important determinant of health. Little research exploring changes in sedentary behavior during behavioral weight loss programs exists. This study evaluated the magnitude of changes in total and prolonged sedentary behavior and how these changes related to changes in weight and cardiovascular outcomes during a behavioral weight loss program. Participants (n = 450) in two lifestyle modification programs underwent assessments of sedentary behavior (by accelerometry), weight, waist circumference, blood pressure, and resting heart rate at baseline and after 6 months of treatment. Sedentary behavior was defined as both total and prolonged (≥30 continuous minutes) sedentary minutes/day. Reductions in total and prolonged sedentary time were significant and were accounted for by increases in moderate-to-vigorous physical activity (MVPA). Only changes in MVPA significantly predicted change in weight when entered into a model simultaneously with changes in sedentary behavior. Changes in total and prolonged sedentary time were not associated with changes in waist circumference, heart rate, or blood pressure. Change in sedentary time was not independently associated with change in health outcomes during a behavioral weight loss treatment. High variability in changes in sedentary time indicate that individual differences may be important to examine. Reducing sedentary time may not be powerful enough to impact these health outcomes above the effects of other changes made during these programs; alternatively, it may be that increasing focus in treatment on reducing sedentary time may engender greater decreases in sedentariness, which could lead to better health outcomes.

Introduction Little is known about the sexual functioning and behavior of men anxious about the size of their penis and the means that they might use to try to alter the size of their penis. Aim To compare sexual functioning and behavior in men with body dysmorphic disorder (BDD) concerning penis size and in men with small penis anxiety (SPA without BDD) and in a control group of men who do not have any concerns. Methods An opportunistic sample of 90 men from the community were recruited and divided into three groups: BDD (n = 26); SPA (n = 31) and controls (n = 33). Main Outcome Measures The Index of Erectile Function (IEF), sexual identity and history; and interventions to alter the size of their penis. Results Men with BDD compared with controls had reduced erectile dysfunction, orgasmic function, intercourse satisfaction and overall satisfaction on the IEF. Men with SPA compared with controls had reduced intercourse satisfaction. There were no differences in sexual desire, the frequency of intercourse or masturbation across any of the three groups. Men with BDD and SPA were more likely than the controls to attempt to alter the shape or size of their penis (for example jelqing, vacuum pumps or stretching devices) with poor reported success. Conclusion Men with BDD are more likely to have erectile dysfunction and less satisfaction with intercourse than controls but maintain their libido. Further research is required to develop and evaluate a psychological intervention for such men with adequate outcome measures. PMID:26468378

Neudesin is involved in anxiety behavior: structural and neurochemical correlates

Directory of Open Access Journals (Sweden)

Ashley eNovais

2013-09-01

Full Text Available Neudesin (also known as neuron derived neurotrophic factor, Nenf is a scarcely studied putative non-canonical neurotrophic factor. In order to understand its function in the brain, we performed an extensive behavioral characterization (motor, emotional and cognitive dimensions of neudesin-null mice. The absence of neudesin leads to an anxious-like behavior as assessed in the elevated plus maze, light/dark box and novelty suppressed feeding tests, but not in the acoustic startle test. This anxious phenotype is associated with reduced dopaminergic input and impoverished dendritic arborizations in the dentate gyrus granule neurons of the ventral hippocampus. Interestingly, shorter dendrites are also observed in the bed nucleus of the stria terminalis (BNST of neudesin-null mice. These findings lead us to suggest that neudesin is a novel relevant player in the maintenance of the anxiety circuitry.

The present study was designed to examine the effects of training in positive interpretations in clinically anxious children. A total of 87 children between 7 and 12 years of age were randomly assigned to either a positive cognitive bias modification training for interpretation (CMB-I) or a neutral training. Training included 15 sessions in a two-week period. Children with an interpretation bias prior to training in the positive training group showed a significant reduction in interpretation bias on the social threat scenarios after training, but not children in the neutral training group. No effects on interpretation biases were found for the general threat scenarios or the non-threat scenarios. Furthermore, children in the positive training did not self-report lower anxiety than children in the neutral training group. However, mothers and fathers reported a significant reduction in social anxiety in their children after positive training, but not after neutral training. This study demonstrated that clinically anxious children with a prior interpretation bias can be trained away from negative social interpretation biases and there is some evidence that this corresponds to reductions in social anxiety. This study also highlights the importance of using specific training stimuli. Copyright © 2015 Elsevier Ltd. All rights reserved.

Both anxiety and alcohol use disorders are among the leading causes of the burden of disease in high-income countries. They co-occur much more often than one would expect based on chance as many anxious individuals drink alcohol to reduce anxiety (Stewart & Conrod, 2008). But in the longer term,

Threat and defense as goal regulation: from implicit goal conflict to anxious uncertainty, reactive approach motivation, and ideological extremism.

Nash, Kyle; McGregor, Ian; Prentice, Mike

2011-12-01

Four studies investigated a goal regulation view of anxious uncertainty threat (Gray & McNaughton, 2000) and ideological defense. Participants (N = 444) were randomly assigned to have achievement or relationship goals implicitly primed. The implicit goal primes were followed by randomly assigned achievement or relationship threats that have reliably caused generalized, reactive approach motivation and ideological defense in past research. The threats caused anxious uncertainty (Study 1), reactive approach motivation (Studies 2 and 3), and reactive ideological conviction (Study 4) only when threat-relevant goals had first been primed, but not when threat-irrelevant goals had first been primed. Reactive ideological conviction (Study 4) was eliminated if participants were given an opportunity to attribute their anxiety to a mundane source. Results support a goal regulation view of anxious uncertainty, threat, and defense with potential for integrating theories of defensive compensation.

What is "normal"? Maternal parenting behavior as risk and protective factor for psychopathology and identity diffusion Objectives: This study analyzes the implications of today's highly altered maternal parenting behaviors on children's development and psychological health. The relationship between maternal parenting behaviors (support, psychological control, and anxious monitoring) and delayed identity development or identity diffusion as well as internalizing or externalizing symptomatology was investigated in a sample of 732 youths (301 adolescents, 351 young adults, and 80 patients). Cluster analysis identified two types of maternal parenting behaviors: authoritative maternal behavior and dysfunctionalmaternal behavior. As expected, patients exhibited a high degree of dysfunctional maternal parenting behavior (low support, high psychological control), delayed identity development as well as elevated identity diffusion and symptomatology.Authoritative maternal parenting emerged as a protective factor in the prediction of identity diffusion and symptomatology.All three groups described a high degree of anxious maternal monitoring. The implications of changed maternal parenting behaviors on identity diffusion and symptomatology are discussed in light of societal changes and changing criteria of personality disorders in the new DSM-5.

Early-life adversity can lead to long-term consequence persisting into adulthood. Here, we assess the implications of an adverse early environment on vulnerability to stress during adulthood. We hypothesized that the interplay between early and late stress would result in a differential phenotype regarding the number of neurons immunoreactive for glucocorticoid receptor (GR-ir) and neuronal activity as assessed by Fos immunoreactivity (Fos-ir) in brain areas related to stress responses and anxiety-like behavior. We also expected that the antidepressant tianeptine could correct some of the alterations induced in our model. Male Wistar rats were subjected to daily maternal separation (MS) for 4.5 h during the first 3 weeks of life. As adults, the rats were exposed to chronic stress for 24 d and they were treated daily with tianeptine (10 mg/kg intraperitoneal) or vehicle (isotonic saline). Fos-ir was increased by MS in all structures analyzed. Chronic stress reduced Fos-ir in the hippocampus, but increased it in the paraventricular nucleus. Furthermore, chronic stress increased GR-ir in hippocampus (CA1) and amygdala in control non-MS rats. By contrast, when MS and chronic stress were combined, GR-ir was decreased in these structures. Additionally, whereas tianeptine did not affect Fos-ir, it regulated GR-ir in a region-dependent manner, in hippocampus and amygdala opposing in some cases the stress or MS effects. Furthermore, tianeptine reversed the MS- or stress-induced anxious behavior. The interplay between MS and chronic stress observed indicates that MS rats have a modified phenotype, which is expressed when they are challenged by stress in later life.

To acknowledge the clinical significance of anxiety in depressed patients, DSM-5 included criteria for an anxious distress specifier for major depressive disorder. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we modified our previously published depression scale to include a subscale assessing the DSM-5 anxious distress specifier. From December 1995 to August 2013, 773 psychiatric outpatients with major depressive disorder completed the Clinically Useful Depression Outcome Scale (CUDOS) supplemented with questions for the DSM-5 anxious distress specifier (CUDOS-A). To examine discriminant and convergent validity, the patients were rated on clinician severity indices of depression, anxiety, and irritability. Discriminant and convergent validity was further examined in a subset of patients who completed other self-report symptom severity scales. Test-retest reliability was examined in a subset who completed the CUDOS-A twice. We compared patients who did and did not meet the DSM-5 anxious distress specifier on indices of psychosocial functioning and quality of life. The CUDOS-A subscale had high internal consistency and test-retest reliability; was more highly correlated with other self-report measures of anxiety than with measures of depression, substance use problems, eating disorders, and anger; and was more highly correlated with clinician severity ratings of anxiety than depression and irritability. CUDOS-A scores were significantly higher in depressed outpatients with a current anxiety disorder than in depressed patients without a comorbid anxiety disorder (P depressive disorder. © Copyright 2014 Physicians Postgraduate Press, Inc.

Effect of prolonged isothermal heat treatment on the mechanical behavior of advanced NANOBAIN steel

Science.gov (United States)

Avishan, Behzad

2017-09-01

The microstructural evolution and consequent changes in strength and ductility of advanced NANOBAIN steel during prolonged isothermal heat-treatment stages were investigated. The microstructure and mechanical properties of nanostructured bainite were not expected to be influenced by extending the heat-treatment time beyond the optimum value because of the autotempering phenomenon and high tempering resistance. However, experimental results indicated that the microstructure was thermodynamically unstable and that prolonged austempering resulted in carbon depletion from high-carbon retained austenite and carbide precipitations. Therefore, austenite became thermally less stable and partially transformed into martensite during cooling to room temperature. Prolonged austempering did not lead to the typical tempering sequence of bainite, and the sizes of the microstructural constituents were independent of the extended heat-treatment times. This independence, in turn, resulted in almost constant ultimate tensile strength values. However, microstructural variations enhanced the yield strength and the hardness of the material at extended isothermal heat-treatment stages. Finally, although microstructural changes decreased the total elongation and impact toughness, considerable combinations of mechanical properties could still be achieved.

1997-11-01

Parents' reports of problem behaviors in 2,081 Dutch children, 3,127 Turkish children in Ankara and 833 Turkish immigrant children living in The Netherlands, aged 4-18 years, were compared. Dutch and Turkish versions of the Child Behavior Checklist (CBCL) were used. Immigrant children were scored higher than Dutch children on 6 of the 11 CBCL scales, most markedly on the Anxious/Depressed scale. Immigrant children were scored higher than Ankara children on five CBCL scales. However, these differences were much smaller than those found between immigrant and Dutch children. Furthermore, immigrant children's Total Problem scores did not differ from those for Ankara children. Turkish immigrant children have very similar patterns of parent-reported problem behaviors to children living in Turkey, although both groups of Turkish children showed higher levels of parent-reported problem behaviors than Dutch children. The higher scores for Turkish children on the Anxious/Depressed scale compared with their Dutch peers may be explained by cultural differences in parental perception of children's problem behaviors, as well as the threshold for reporting them, or by cultural differences in the prevalence of problems, for instance as the result of cross-cultural differences in child-rearing practice. More research is needed to test the degree to which Turkish immigrant parents tend to preserve their cultural characteristics and child-rearing practices in Dutch society.

Objective To investigate relationships of depressed parents' attachment style to offspring suicidal behavior. Method 244 parents diagnosed with a DSM-IV depressive episode completed the Adult Attachment Questionnaire at study entry. Baseline and yearly follow-up interviews of their 488 offspring tracked suicidal behavior and psychopathology. Survival analysis and marginal regression models with correlated errors for siblings investigated the relationship between parent insecure attachment traits and offspring characteristics. Data analyzed were collected 1992–2008 during a longitudinal family study completed January 31, 2014. Results Parent avoidant attachment predicted offspring suicide attempts at a trend level (p=0.083). Parent anxious attachment did not predict offspring attempts (p=0.961). In secondary analyses, anxious attachment in parents was associated with offspring impulsivity (p=0.034), and in offspring suicide attempters, was associated with greater intent (p=0.045) and lethality of attempts (p=0.003). Avoidant attachment in parents was associated with offspring impulsivity (p=0.025) and major depressive disorder (p=0.012). Parent avoidant attachment predicted a greater number of suicide attempts (p=0.048) and greater intent in offspring attempters (p=0.003). Results were comparable after adjusting for parent diagnosis of borderline personality disorder. Conclusion Insecure avoidant, but not anxious, attachment in depressed parents may predict offspring suicide attempt. Insecure parent attachment traits were associated with impulsivity and major depressive disorder in all offspring, and with more severe suicidal behavior in offspring attempters. Insecure parental attachment merits further study as a potential target to reduce risk of offspring psychopathology and more severe suicidal behavior. PMID:25098943

2006-06-01

This study investigated DSM-defined anxiety symptoms in South African youths. Children and adolescents (N = 701) from various cultural groups completed the SCARED and a questionnaire measuring perceived parental rearing behaviors. Results indicated that the psychometric properties of the SCARED were satisfactory in the total sample of South African youths, and acceptable in colored and black children and adolescents. Further, colored and black youths displayed higher SCARED scores than white youths, and there were also differences in the perceived parental rearing behaviors of the cultural groups. White youths generally rated their parents' rearing behaviors as less anxious, overprotective, and rejective, but more emotionally warm than colored and black youths. Finally, positive correlations were found between anxious rearing, overprotection, and rejection and anxiety symptoms. The clinical and research implications of these findings are briefly discussed.

Background and aims Pathological gambling is associated with comorbid disorders, such as anxiety, depression, and drug and alcohol abuse. Difficulties of emotion regulation may be one of the factors related to the presence of addictive disorders, along with comorbid symptomatology in pathological gamblers. Therefore, the aim of this study was to evaluate the difficulties of emotion regulation, drug and alcohol abuse, and anxious and depressive symptomatology in pathological gamblers, and the mediating role of difficulties of emotion regulation between anxiety and pathological gambling. Methods The study sample included 167 male pathological gamblers (mean age = 39.29 years) and 107 non-gamblers (mean age = 33.43 years). Pathological gambling (SOGS), difficulties of emotion regulation (DERS), drug and alcohol abuse (MUTICAGE CAD-4), and anxious and depressive symptomatology (SA-45) were measured. Student's t, Pearson's r, stepwise multiple linear regression and multiple mediation analyses were conducted. The study was approved by an Investigational Review Board. Results Relative to non-gamblers, pathological gamblers exhibited greater difficulties of emotion regulation, as well as more anxiety, depression, and drug abuse. Moreover, pathological gambling correlated with emotion regulation difficulties, anxiety, depression, and drug abuse. Besides, emotion regulation difficulties correlated with and predicted pathological gambling, drug and alcohol abuse, and anxious and depressive symptomatology. Finally, emotion regulation difficulties mediated the relationship between anxiety and pathological gambling controlling the effect of age, both when controlling and not controlling for the effect of other abuses. Discussion and conclusions These results suggest that difficulties of emotion regulation may provide new keys to understanding and treating pathological gambling and comorbid disorders.

Numerous websites offer direct-to-consumer (DTC) genetic testing, yet it is unknown how individuals will react to genetic risk profiles online. The objective of this study was to determine the feasibility of using a web-based survey and conjoint methods to elicit individuals' interpretations of genetic risk profiles by their anticipated worry/anxiousness and health-seeking behaviors. A web-based survey was developed using conjoint methods. Each survey presented 12 hypothetical genetic risk profiles describing genetic test results for four diseases. Test results were characterized by the type of disease (eight diseases), individual risk (five levels), and research confidence (three levels). After each profile, four questions were asked regarding anticipated worry and health-seeking behaviors. Probabilities of response outcomes based on attribute levels were estimated from logistic regression models, adjusting for covariates. Overall, 319 participants (69%) completed 3828 unique genetic risk profiles. Across all profiles, most participants anticipated making doctor's appointments (63%), lifestyle changes (57%), and accessing screening (57%); 40% anticipated feeling more worried and anxious. Higher levels of disease risk were significantly associated with affirmative responses. Conjoint methods may be used to elicit reactions to genetic information online. Preliminary results suggest that genetic information may increase worry/anxiousness and health-seeking behaviors among consumers of DTC tests. Further research is planned to determine the appropriateness of these affects and behaviors.

Hypercortisolemia is one of the clinical features found in depressed patients. This clinical feature has been mimicked in animal studies via application of exogenous corticosterone (CORT). Previous studies suggested that CORT can induce behavioral disturbance in anxious-depressive like behavior, which is associated with suppressed neurogenesis. Hippocampal neurogenesis plays an important role in adult cognitive and behavioral regulation. Its suppression may thus lead to neuropsychiatric disor...

Attention biases to threat and behavioral inhibition in early childhood shape adolescent social withdrawal.

Behavioral inhibition (BI) is a temperament characterized in young children by a heightened sensitivity to novelty, social withdrawal, and anxious behaviors. For many children, these social difficulties dissipate over time. For others, patterns of social withdrawal continue into adolescence. Over time, attention biases to threat may influence the stability of BI and its association with social withdrawal, ultimately modulating the risk for anxiety disorders in BI children. However, we know relatively little about the cognitive processes that accompany BI and shape later socio-emotional functioning. We examined the relations among BI in childhood, attention biases to threat in adolescence, and adolescent social withdrawal in a longitudinal study (N = 126, Mean age = 15 years). As has been reported in anxious adults, adolescents who were behaviorally inhibited as toddlers and young children showed heightened attention bias to threat. In addition, attention bias to threat moderated the relation between childhood BI and adolescent social withdrawal.

Binge-pattern cocaine administration causes long-lasting behavioral hyperarousal but does not enhance vulnerability to single prolonged stress in rats.

Cocaine use disorder and post-traumatic stress disorder (PTSD) commonly co-occur. This could be due to vulnerability to post-traumatic symptoms conferred by previous exposure to cocaine. Therefore, we combined chronic binge-pattern cocaine with a model of psychological trauma (single prolonged stress) to determine whether the behavioral effects of psychological trauma are enhanced in cocaine-sensitized individuals. Adult male Sprague Dawley rats received 14 days of cocaine (15mg/kg/injection) or saline in a binge pattern (3 injections per day, 1h apart). Seven days after the last injection animals were exposed to traumatic stress or a control procedure. Seven days after stress, activity and anxiety-like behaviors were measured. Binge-pattern cocaine increased locomotor activity in the open field and elevated plus maze, and both cocaine and SPS exposure increased the rapidity with which rats moved through grooming sequences. Neither binge-pattern cocaine nor SPS increased anxiety-like behaviors, and no interactions were found between binge-pattern cocaine exposure and SPS exposure. A behavioral phenotype categorization approach demonstrated that cocaine-exposed groups expressed a high incidence of hyperactivity-like symptoms. These results suggest that binge-pattern cocaine exposure causes a long-lasting hyper-exploratory phenotype but does not make individuals more vulnerable to a later traumatic stress exposure.

A network consisting of left dorsolateral prefrontal cortex (LDLPFC) and dorsal anterior cingulate cortex (dACC) has been implicated in top-down attentional control. Few studies have systematically investigated how this network is altered in psychopathology, despite evidence that depression and anxiety are associated with attentional control impairments. Functional MRI and dense-array event-related brain potential (ERP) data were collected in separate sessions from 100 participants during a color-word Stroop task. Functional MRI results guided ERP source modeling to characterize the time course of activity in LDLPFC (300-440 ms) and dACC (520-680 ms). At low levels of depression, LDLPFC activity was indirectly related to Stroop interference and only via dACC activity. In contrast, at high levels of depression, dACC did not play an intervening role, and increased LDLPFC activity was directly related to decreased Stroop interference. Specific to high levels of anxious apprehension, higher dACC activity was related to more Stroop interference. Results indicate that depression and anxious apprehension modulate temporally and functionally distinct aspects of the frontocingulate network involved in top-down attention control.

Perceiving Partners to Endorse Benevolent Sexism Attenuates Highly Anxious Women's Negative Reactions to Conflict.

Science.gov (United States)

Cross, Emily J; Overall, Nickola C; Hammond, Matthew D

2016-07-01

Benevolent sexism prescribes that men are dependent on women in relationships and should cherish their partners. The current research examined whether perceiving male partners to endorse benevolent sexism attenuates highly anxious women's negative reactions to relationship conflict. Greater attachment anxiety was associated with greater distress and insecurity during couples' conflict discussions (Study 1), during daily conflict with intimate partners (Study 2), and when recalling experiences of relationship conflict (Study 3). However, this heightened distress and insecurity was attenuated when women (but not men) perceived their partner to strongly endorse benevolent sexism (Studies 1-3) and thus believed their partner could be relied upon to remain invested (Study 3B). These novel results illustrate that perceiving partners to endorse benevolent sexism alleviates anxious women's insecure reactions to relationship threat by conveying partner's continued reliability. Implications of these security-enhancing effects are considered in light of the role benevolent sexism plays in sustaining gender inequality. © 2016 by the Society for Personality and Social Psychology, Inc.

2007-01-01

Full Text Available Pain is not the sole reason for fear of dentistry. Anxiety or the fear of unknown during dental treatment is a major factor and it has been the major concern for dentists for a long time. Therefore, the main aim of this study was to evaluate and compare the two distraction techniques, viz, audio distraction and audiovisual distraction, in management of anxious pediatric dental patients. Sixty children aged between 4-8 years were divided into three groups. Each child had four dental visits - screening visit, prophylaxis visit, cavity preparation and restoration visit, and extraction visit. Child′s anxiety level in each visit was assessed using a combination of four measures: Venham′s picture test, Venham′s rating of clinical anxiety, pulse rate, and oxygen saturation. The values obtained were tabulated and subjected to statistical analysis. It was concluded that audiovisual distraction technique was more effective in managing anxious pediatric dental patient as compared to audio distraction technique.

Asbestos is known to be an independent risk factor for lung and pleural cancers. However, to date, little attention has been paid to the psychological effects of asbestos exposure among exposed subjects. The objectives of this study were to estimate the prevalence of anxious and depressive symptoms among >2000 French participants of the Asbestos-Related Diseases Cohort (ARDCO), 6 years after their inclusion, to identify the risk factors associated with those anxious and depressive symptoms and to evaluate the impact of the asbestos-risk perception. The ARDCO was constituted in four regions of France between October 2003 and December 2005, by including former asbestos workers. Between 2011 and 2012, participants of the ARDCO program were invited to undergo another chest CT scan 6 years after the previous scan. Participants were asked to complete questionnaires including asbestos exposure assessment, Hospital Anxiety and Depression Scale (HADS), asbestos-risk perception and self-perception of asbestos-related diseases. Among the 2225 participants, 2210 fully completed questionnaires were collected and analyzed. The prevalence of symptoms of probable anxiety and probable depression was 19.7% and 9.9%, respectively. The risk of anxious and depressive symptoms was independently associated with self-perception of the intensity of asbestos exposure, asbestos-risk perception and self-perception of asbestos-related diseases. The results obtained in this large study confirm that previously asbestos-exposed subjects are likely to develop anxious and depressive symptoms. Finally, implications related to the prevention of anxiety and depression among asbestos-exposed workers is discussed. © The Author 2016.

Stevens, Stephan; Cludius, Barbara; Bantin, Trisha; Hermann, Christiane; Gerlach, Alexander L

2014-02-01

Social anxiety disorder and alcohol use disorders are highly comorbid. It remains unclear, however, if and how alcohol influences attentional processes and physical symptoms in social anxiety. In a balanced-placebo-design, high and normally socially anxious participants gave a speech while performing a task, which simultaneously measures internal and external attention. Only high anxious participants showed a preferential processing of external probes, which was eliminated by alcohol or the mere expectation of drinking alcohol. Furthermore, alcohol reduced facial blushing as well as self-reported social anxiety during public speaking. Decreases in anxiety were significantly associated with a reduction of the external focus in the high anxious group. Understanding alcohol as a substance influencing cognitive processes as well as physiological symptoms of anxiety further contributes to our understanding of alcohol use as a safety behavior in social anxiety disorder.

Full Text Available We investigated the time course of neural processing of multi-digit additions in high- (HMA and low-math anxious (LMA individuals. Seventeen HMA and 17 LMA individuals were presented with two-digit additions and were asked to perform a verification task. Behavioral data showed that HMA were slower and more error prone than their LMA peers, and that incorrect solutions were solved more slowly and less accurately than correct ones. Moreover, HMA individuals tended to need more time and commit more errors when having to verify incorrect solutions than correct ones. They also took longer and made more errors than their LMA peers. ERPs time-locked to the presentation of the addends (calculation phase and to the presentation of the proposed solution (verification phase were also analyzed. In both phases, a P2 component of larger amplitude was found for HMA individuals than for their LMA peers. Moreover, in the verification phase, LMA individuals showed a larger late positive component (LPC for incorrect solutions at parietal electrodes than their HMA counterparts. Because the P2 component is considered to be a biomarker of the mobilization of attentional resources towards emotionally negative stimuli, these results suggest that HMA individuals may invest more attentional resources during the arithmetical

Full Text Available Abstract Background In the Netherlands, the prevalence of anxiety disorders is 20%; and children with anxiety are at increased risk for psychopathology throughout adulthood. Recently, a revised version of a cognitive behavioral therapy manualized program called 'Thinking + Doing = Daring' (TDD was developed for children between 8 and 12 years old with an anxiety disorder. The main aim of this project is to conduct a Randomized Controlled Trial (RCT to evaluate the effectiveness of TDD. Methods/Design The CBT program will be tested with a RCT with 120 clinically anxious children (8-12 years old referred to one of three mental health care agencies. Children will be randomly assigned to the experimental (N = 60, TDD or to the control condition (N = 60, treatment as usual. The primary outcome measure will be the child's anxiety symptoms level. Secondary outcome measures will be externalizing (e.g. aggression and internalizing problems (e.g. depression. Two potential mediators of change will be examined in the current study: therapeutic alliance and parenting. Mother and child in both the experimental and control condition will be surveyed at baseline, post treatment and after 6 and 12 months (follow-up. It is hypothesized that children in the experimental condition will show a stronger decrease in anxiety symptoms compared to children that receive treatment as usual. Moreover, we expect that a strong therapeutic alliance and decreases in parental control and rejection will contribute to treatment success. Discussion Early treatment for anxiety problems has the potential to not only result in anxiety reductions, but also to prevent future problems such as substance abuse and psychopathology throughout adulthood. Our results will be immediately relevant to practice, since we are partnering with 'real world' community agencies. If the CBT program proves more effective than treatment as usual, it could be implemented in community mental health care

Reactive, anxious and possessive forms of jealousy and their relation to relationship quality among heterosexuals and homosexuals.

Barelds, Dick P H; Dijkstra, Pieternel

2006-01-01

The present study examined the relationship between relational quality and three different types of jealousy-reactive, anxious and possessive jealousy. The sample consisted of 76 gay men, 79 lesbians, 70 heterosexual women and 70 heterosexual men. Findings show that different types of jealousy affect relationship quality differently and do so differently for homosexuals and heterosexuals. Among heterosexuals and especially gay men--but not among lesbians--anxious jealousy was negatively related to relationship quality. In contrast, among heterosexuals--but not among gay men or lesbians--reactive jealousy was positively related to relationship quality. The present study shows that distinguishing between different types of jealousy is necessary to entangle the diverse effects of jealousy on the quality of homosexual and heterosexual relationships.

Satisfying needs through Social Networking Sites: A pathway towards problematic Internet use for socially anxious people?

Casale, Silvia; Fioravanti, Giulia

2015-06-01

Following the theoretical frameworks of the dual-factor model of Facebook use and the Self Determination Theory, the present study hypothesizes that the satisfaction of unmet needs through Social Networking Sites (SNSs) may represent a pathway towards problematic use of Internet communicative services (GPIU) for socially anxious people. Four hundred undergraduate students (females = 51.8%; mean age = 22.45 + 2.09) completed three brief scales measuring the satisfaction via SNSs of the need to belong, the need for self-presentation and the need for assertiveness, the Generalized Problematic Internet Use Scale 2 and the Social Interaction Anxiety Scale. Structural equation modeling was performed separately for males and females. A direct effect of social anxiety on GPIU was found among both genders. Socially anxious males and females tend to use SNSs for self-presentation purposes, as well as for the opportunity to be more assertive. The association between social anxiety and GPIU was partially mediated by the need for self-presentation only among males. The present results extend our understanding of the development of problematic use of Internet communicative services, based on the framework of the dual factor model of Facebook use and the Self Determination Theory. The fulfillment of an unmet need for self-presentation (i.e. the desire to create a positive impression of one's self in others) through SNSs could be one of the possible pathways to GPIU for socially anxious males.

Full Text Available Marie-France Leblanc,1 Sophie Desjardins,1 Alain Desgagné2 1Department of Psychology, Université du Québec à Trois-Rivières, Trois-Rivières, 2Department of Mathematics, Université du Québec à Montréal, Montréal, QC, Canada Purpose: The objective of this study was to identify the sleep problems most often encountered by the elderly according to the presence or absence of anxiety and mood disorders. The aim was also to determine whether groups of anxious, depressive, and asymptomatic individuals differ in relation to sleep onset latency; awakenings at night or early in the morning; subjective quality of sleep; taking of sleep medication; and daytime sleepiness. Methods: Structured interviews based on the DSM-IV-TR were administered to a sample of 2,759 seniors aged 65 years and older at the participants’ home by health professionals. Results: Awakening was found to be the most common disturbance. Increased sleep onset latency was the second most frequent sleep difficulty. Taking more than 30 minutes to fall asleep was associated with the likelihood of meeting the diagnostic criteria for an anxiety disorder, and even reduced the risk of meeting the diagnostic criteria for a mood disorder rather than an anxiety disorder. Awakenings were associated with the probability of suffering from an anxiety disorder or a mood disorder. Quality of sleep, as perceived by the elderly, was not found to be associated with the probability of suffering from a mental disorder. Conclusion: These findings should help to facilitate the practitioner’s diagnosis and add further nuances to be considered when encountering symptoms of an anxious or depressive appearance. All of these data also add fuel to the ongoing debate about whether anxiety and depression are one or two distinct categories of disorders. Keywords: anxiety, awakenings, daytime sleepiness, depression, elderly, quality of sleep, sleep medication, sleep onset latency

High-anxious individuals show increased chronic stress burden, decreased protective immunity, and increased cancer progression in a mouse model of squamous cell carcinoma.

Full Text Available In spite of widespread anecdotal and scientific evidence much remains to be understood about the long-suspected connection between psychological factors and susceptibility to cancer. The skin is the most common site of cancer, accounting for nearly half of all cancers in the US, with approximately 2-3 million cases of non-melanoma cancers occurring each year worldwide. We hypothesized that a high-anxious, stress-prone behavioral phenotype would result in a higher chronic stress burden, lower protective-immunity, and increased progression of the immuno-responsive skin cancer, squamous cell carcinoma. SKH1 mice were phenotyped as high- or low-anxious at baseline, and subsequently exposed to ultraviolet-B light (1 minimal erythemal dose (MED, 3 times/week, 10-weeks. The significant strengths of this cancer model are that it uses a normal, immunocompetent, outbred strain, without surgery/injection of exogenous tumor cells/cell lines, and produces lesions that resemble human tumors. Tumors were counted weekly (primary outcome, and tissues collected during early and late phases of tumor development. Chemokine/cytokine gene-expression was quantified by PCR, tumor-infiltrating helper (Th, cytolytic (CTL, and regulatory (Treg T cells by immunohistochemistry, lymph node T and B cells by flow cytometry, adrenal and plasma corticosterone and tissue vascular-endothelial-growth-factor (VEGF by ELISA. High-anxious mice showed a higher tumor burden during all phases of tumor development. They also showed: higher corticosterone levels (indicating greater chronic stress burden, increased CCL22 expression and Treg infiltration (increased tumor-recruited immuno-suppression, lower CTACK/CCL27, IL-12, and IFN-γ gene-expression and lower numbers of tumor infiltrating Th and CTLs (suppressed protective immunity, and higher VEGF concentrations (increased tumor angiogenesis/invasion/metastasis. These results suggest that the deleterious effects of high trait anxiety

Depression and anxiety disorders are highly comorbid, and share significant symptom overlap. Whereas depression has been consistently associated with excess mortality, the association between anxiety and mortality is less clear. Our aim was to identify constellations of anxious and depressive symptoms and examine their associations with mortality. This study considers respondents from the 1970 (n = 1203) and 1992 (n = 1402) cohorts of the Stirling County study. Symptoms of depression and anxiety were assessed using structured at-home interviews. Vital status of participants through 2011 was determined using probabilistic linkages to the Canadian Mortality Database. Exploratory factor analysis yielded three correlated factors in each cohort. Items loading on each factor varied slightly between cohorts, but roughly corresponded to (1) depressive symptoms, (2) anxious symptoms, and (3) somatic symptoms. The depressive factor was associated with increased risk of mortality in both the 1970 (HR: 1.35, 95% CI: 1.12, 1.62) and 1992 (HR: 1.25, 95% CI: 1.05, 1.48) cohorts. Anxious symptoms were associated with a reduced risk of mortality in the 1992 sample (HR: 0.72; 95% CI: 0.53, 0.90). Somatic symptoms were associated with a reduced risk of mortality in the 1970 sample (HR: 0.83, 95% CI: 0.69, 0.99), but an elevated risk of mortality in the 1992 sample (HR: 1.29; 95% CI: 1.11, 1.51). This study provides evidence that symptoms of depression and anxiety may have differential associations with early mortality. Somatic symptoms such as upset stomach and loss of appetite may be protective against mortality, perhaps through increased use of health care services. Conversely, symptoms such as weakness and cold sweats may be indicative of failing health. © 2018 Wiley Periodicals, Inc.

Cognitive Behaviour Therapy (CBT) is an effective treatment for childhood anxiety disorders, yet a significant proportion of children do not benefit from it. CBT for child anxiety disorders typically includes a range of strategies that may not all be applicable for all affected children. This study explored whether there are distinct subgroups of children with anxiety disorders who are characterized by their responses to measures of the key mechanisms that are targeted in CBT (i.e. interpretation bias, perceived control, avoidance, physiological arousal, and social communication). 379 clinically anxious children (7-12 years) provided indices of threat interpretation, perceived control, expected negative emotions and avoidance and measures of heart rate recovery following a speech task. Parents also reported on their children's social communication difficulties using the Social Communication Questionnaire (SCQ). Latent profile analysis identified three groups, reflecting (i) 'Typically anxious' (the majority of the sample and more likely to have Generalized anxiety disorder); (ii) 'social difficulties' (characterized by high SCQ and more likely to have social anxiety disorder and be male); (iii) 'Avoidant' (characterized by low threat interpretation but high avoidance and low perceived control). Some measures may have been influenced by confounding variables (e.g. physical variability in heart rate recovery). Sample characteristics of the group may limit the generalizability of the results. Clinically anxious children appear to fall in to subgroups that might benefit from more targeted treatments that focus on specific maintenance factors. Treatment studies are now required to establish whether this approach would lead to more effective and efficient treatments. Copyright © 2018 The Authors. Published by Elsevier B.V.

In addition to insufficient moderate-to-vigorous physical activity (MVPA), prolonged sitting time is also a health risk for older adults. An understanding of population subgroups who have prolonged television viewing (TV) time, a predominant sedentary behavior, can aid in the development of relevant health promotion initiatives; however, few such studies have focused on older adults, the most sedentary segment of the population as a whole. The aim of this study is to examine the socio-demographic attributes associated with TV time among community-dwelling Japanese older men and women. A population-based, cross-sectional mail survey was used to collect data on TV time, MVPA, and socio-demographic characteristics. The survey was conducted from February through March 2010. Participants were 2700 community-dwelling older adults (aged 65-74 years, 50% men) who were randomly selected from the registry of residential addresses of three cities in Japan. Data from 1665 participants (mean age: 69.5 years, 52% men) who completed all variables for the present study were analyzed. Multivariate logistic regression analyses were used to calculate the odds ratios (ORs) of prolonged TV time (>2 hours/day) for each socio-demographic attribute, stratified by gender. Of the 1665 participants, 810 (48.6%) watched TV for more than 2 hours/day. The median television viewing time (25th, 75th percentile) was 2.00 (1.07, 3.50) hours/day. Prolonged TV time was associated with not in full-time employment, lower educational attainment, weight status, living in regional areas and low MVPA for the whole sample. For men, prolonged TV time was associated with lower educational attainment; (OR = 1.53, 95% CI: 1.12-2.07), underweight (OR = 1.63, 95% CI: 1.02-2.60), overweight (OR = 1.57, 95% CI: 1.11-2.21), and low MVPA (OR = 1.43, 95% CI: 1.02-2.02). For women, living in regional areas (OR = 2.02, 95% CI: 1.33-3.08), living alone (OR = 1.61, 95% CI: 1.03-2.49), not driving

Cataplexy in anxious patients: is subclinical narcolepsy underrecognized in anxiety disorders?

Flosnik, Dawn L; Cortese, Bernadette M; Uhde, Thomas W

2009-06-01

Excessive daytime sleepiness, hypnagogic-hypnopompic hallucinations, sleep paralysis, and cataplexy are symptoms associated with narcolepsy. Recent findings indicate that anxiety disorders also are associated with excessive daytime sleepiness, hypnagogic-hypnopompic hallucinations, and sleep paralysis. These observations suggest a possible relationship between anxiety disorders and narcolepsy. Cataplexy is considered the most specific symptom of narcolepsy, but its association with anxiety disorders is unknown. This preliminary investigation examined the prevalence and types of cataplexy in patients with primary anxiety disorders. Sex- and age-matched patients with anxiety disorders (N = 33) and healthy volunteers (N = 33) were assessed on standardized and validated measures of subjective sleep quality (Pittsburgh Sleep Quality Index) and subclinical narcoleptic events in the form of cataplexy (Stanford Center for Narcolepsy Revised Sleep Inventory). Patients were recruited from October 2006 to January 2007 from 2 programs of the Penn State Behavioral Health Clinic. Anxiety disorder patients as a group reported poorer sleep quality and endorsed a larger number of different types of situations (e.g., surprise, embarrassment) associated with cataplectic events. Among anxious patients, 33.3% (11 of 33) endorsed events specific for classic cataplexy, as opposed to 9.1% (3 of 33) of healthy volunteers (chi(2) = 5.80, p = .016). Our preliminary findings suggest that anxiety disorders are associated with increased rates of cataplexy. Future research is indicated to elucidate the relationship between anxiety and narcolepsy, with a particular focus on panic and generalized anxiety disorders.

2012-09-01

Not everyone who takes drugs becomes addicted, but the likelihood of developing drug addiction is greater in people with a family history of drug or alcohol dependence. Relatively little is known about how genetic risk mediates the development of drug dependence. By comparing the phenotypic profile of individuals with and without a family history of addiction, the authors sought to clarify the extent to which cognitive dysfunction and personality traits are shared by family members--and therefore likely to have predated drug dependence--and which aspects are specific to drug-dependent individuals. The authors assessed cognitive function and personality traits associated with drug dependence in stimulant-dependent individuals (N=50), their biological siblings without a history of drug dependence (N=50), and unrelated healthy volunteers (N=50). Cognitive function was significantly impaired in the stimulant-dependent individuals across a range of domains. Deficits in executive function and response control were identified in both the stimulant-dependent individuals and in their non-drug-dependent siblings. Drug-dependent individuals and their siblings also exhibited elevated anxious-impulsive personality traits relative to healthy comparison volunteers. Deficits in executive function and response regulation as well as anxious-impulsive personality traits may represent endophenotypes associated with the risk of developing cocaine or amphetamine dependence. The identification of addiction endophenotypes may be useful in facilitating the rational development of therapeutic and preventive strategies.

Psychological therapists commonly fail to adhere to treatment protocols in everyday clinical practice. In part, this pattern of drift is attributable to anxious therapists being less likely to undertake some elements of evidence-based therapies - particularly the exposure-based elements. This study considers what facets of anxiety (cognitive, behavioral, physiological) are related to junior clinicians' reported use of cognitive-behavioral therapy techniques. Thirty-two clinicians (mean age = 28.9 years; mean length of CBT experience = 1.5 years; 23 female, nine male) who offered CBT were assessed for their cognitive, behavioral and physiological characteristics (Intolerance of Uncertainty scale; risk taking; skin conductance response and heart rate variability). While the three different facets of anxiety were relatively poorly associated with each other, as is usual in this literature, each facet was linked differently to the reported delivery of CBT techniques (P behavioral or cognitive methods. Of the three facets of anxiety, only physiological reactivity showed an association with the clinicians' temporal characteristics, with more experienced therapists being more likely to have greater skin conductance responses to positive and negative outcomes. These findings suggest that clinicians who are more anxious are less likely to deliver the full evidence-based form of CBT and to focus instead on less challenging elements of the therapy. Potential ways of overcoming this limitation are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

Prolonged Exposure Therapy For Post Traumatic Stress Disorder

Levent SÜTÇİGİL

2012-07-01

Full Text Available Post-traumatic Stress Disorder (PTSD is a psychiatric illness that usually develops after an event that threatens one’s life and body integrity and it affects quality of life and impairs social functioning significantly. Many studies have shown therapeutic effect of cognitive behavioral therapies on posttraumatic stress disorder, so that these therapies take part in the first step of treatment guides. Exposure is a practice that is generally used to reduce pathological fear and related emotions common in posttraumatic stress disorder (PTSD and other anxiety disorders. During exposure, patients intentionally confront with feared objects, situations, thoughts and similar stimuli in order to reduce anxiety level. Exposure can be divided into two main techniques as in vivo exposure and imaginal exposure. Prolonged exposure therapy is a specialized treatment program configured for the treatment of posttraumatic stress disorder and it is based on emotional processing theory. Program is comprised of four main components: (a Psycho-education about trauma and posttraumatic disorders, (b Training for breathing exercises, (c repeated facing with objects, persons, situations and thoughts which causes re-experience about trauma, (d Patient are instructed for telling repeatedly and loudly about traumatic experiences . Prolonged exposure usually involves 9 to 12 sessions, each lasting about 60-90 minutes, administered once or twice a week. Prolonged exposure therapy was started to be implemented since the 1980s, during this period the effectiveness of the therapy has been shown in various empirical studies.

A growing body of literature suggests that parents play a critical role in the development and/or maintenance of child anxiety. One of the main purposes of this article is to identify common parental involvement techniques and most common obstacles derived from parents in cognitive behavioral therapy (CBT) with anxious children. Another purpose of the present study is to revise empirical studies comparing child-focused CBT with and without parental involvement. The PsycARTICLES, MEDLINE and PubMed databases were searched to identify articles in English that were published between the years of 1990 and 2012 (October) using the following keywords; (1) anxiety, (2) cognitive behavioral therapy, (3) parental involvement. Studies were only included in this review if they were comparing the treatment effect of child-only CBT and CBT with additional parental components. Thirteen studies were introduced in the context of method (diagnosis of children, age range of children, follow-up, results, etc.) and therapy characteristics (number of sessions, frequency of sessions, treatment components both child focused CBT and CBT with parental involvement, etc.). The common techniques of therapy with parental involvement are psychoeducation, contingency management, cognitive restructuring, reducing parental anxiety, improving parent-child relationship, and relapse prevention. Parental psychopathology, parental inappropriate expectations and family dysfunctions are important difficulties derived from parents in CBT with anxious children. The results of the studies suggested that parental involvement have increased the efficacy of the treatment in CBT especially working with young children and having at least one anxious parent.

Licences of US nuclear reactors were initially attributed for a 40 years duration. However, the vast majority of the reactors can benefit of a licence prolongation for a period of 20 years maximum. This article recalls first the procedure to follow for the licence prolongation demands (safety analysis, components aging, environmental impact statement), and then it makes a status of the accepted prolongations, of the demands under examination, and of the demands that should be presented in the next 5 years.

Trait anxiety is believed to be a hierarchical construct composed of several lower-order factors (Adv. Behav. Res. Therapy, 15 (1993) 147; J. Anxiety Disorders, 9 (1995) 163). Assessment devices such as the Social Interaction Anxiety Scale, the Social Phobia Scale (SIAS and SPS; Behav. Res. Therapy, 36 (4) (1998) 455), and the Anxiety Sensitivity Index (ASI; Behav. Res. Therapy, 24 (1986) 1) are good measures of the presumably separate lower-order factors. This study compared the effectiveness of the SIAS, SPS, ASI-physical scale and STAI-T (State-Trait Anxiety Inventory. Palo Alto, CA: Consulting Psychologists Press (1970)) as predictors of anxious response to a social challenge (asking an aloof confederate out on a date). Consistent with the hierarchical model of anxiety, the measures of trait anxiety were moderately correlated with each other and each was a significant predictor of anxious response. The specific measures of trait social anxiety were slightly better predictors of anxious response to the social challenge than was either the ASI-physical scale or the STAI-T. The results provide evidence of the predictive validity of these social trait measures and some support for their specificity in the prediction of anxious response to a social challenge.

Previous research revealed an automatic behavioral bias in high socially anxious individuals (HSAs): although their explicit evaluations of smiling faces are positive, they show automatic avoidance of these faces. This is reflected by faster pushing than pulling of smiling faces in an Approach-Avoidance Task (AAT; Heuer et al., 2007). The current study addressed the causal role of this avoidance bias for social anxiety. To this end, we used the AAT to train HSAs, either to approach smiling faces or to avoid them. We examined whether such an AAT training could change HSAs' automatic avoidance tendencies, and if yes, whether AAT effects would generalize to a new approach task with new facial stimuli, and to mood and anxiety in a social threat situation (a video-recorded self-presentation). We found that HSAs trained to approach smiling faces did indeed approach female faces faster after the training than HSAs trained to avoid smiling faces. Moreover, approach-faces training reduced emotional vulnerability: it led to more positive mood and lower anxiety after the self-presentation than avoid-faces training. These results suggest that automatic approach-avoidance tendencies have a causal role in social anxiety, and that they can be modified by a simple computerized training. This may open new avenues in the therapy of social phobia. PMID:23970862

Full Text Available Post-traumatic Stress Disorder (PTSD is a psychiatric illness that usually develops after an event that threatens one’s life and body integrity and it affects quality of life and impairs social functioning significantly. Many studies have shown therapeutic effect of cognitive behavioral therapies on posttraumatic stress disorder, so that these therapies take part in the first step of treatment guides. Exposure is a practice that is generally used to reduce pathological fear and related emotions common in posttraumatic stress disorder (PTSD and other anxiety disorders. During exposure, patients intentionally confront with feared objects, situations, thoughts and similar stimuli in order to reduce anxiety level. Exposure can be divided into two main techniques as in vivo exposure and imaginal exposure. Prolonged exposure therapy is a specialized treatment program configured for the treatment of posttraumatic stress disorder and it is based on emotional processing theory. Program is comprised of four main components: (a Psycho-education about trauma and posttraumatic disorders, (b Training for breathing exercises, (c repeated facing with objects, persons, situations and thoughts which causes re-experience about trauma, (d Patient are instructed for telling repeatedly and loudly about traumatic experiences . Prolonged exposure usually involves 9 to 12 sessions, each lasting about 60-90 minutes, administered once or twice a week. Prolonged exposure therapy was started to be implemented since the 1980s, during this period the effectiveness of the therapy has been shown in various empirical studies.

Duplex kidney is a common anomaly that is frequently associated with multiple complications. Typical computed tomography urography (CTU) includes four phases (unenhanced, arterial, parenchymal and excretory) and has been suggested to considerably aid in the duplex kidney diagnosi. Unfortunately, regarding duplex kidney with prolonged dilatation, the affected parenchyma and tortuous ureters demonstrate a lack of or delayed excretory opacification. We used prolonged-delay CTU, which consists of another prolonged-delay phase (1- to 72-h delay; mean delay: 24 h) to opacify the duplicated ureters and affected parenchyma. Seventeen patients (9 males and 8 females; age range: 2.5-56 y; mean age: 40.4 y) with duplex kidney were included in this study. Unenhanced scans did not find typical characteristics of duplex kidney, except for irregular perirenal morphology. Duplex kidney could not be confirmed on typical four-phase CTU, whereas it could be easily diagnosed in axial and CT-3D reconstruction using prolonged CTU (prolonged-delay phase). Between January 2005 and October 2010, in this review board-approved study (with waived informed consent), 17 patients (9 males and 8 females; age range: 2.5 ~ 56 y; mean age: 40.4 y) with suspicious duplex kidney underwent prolonged CTU to opacify the duplicated ureters and confirm the diagnosis. Our results suggest the validity of prolonged CTU to aid in the evaluation of the function of the affected parenchyma and in the demonstration of urinary tract malformations.

To correlate lipid metabolism and autonomic dysfunction with anxious-depressive spectrum and eating disorders. To propose the lipid index (LI) as a new possible biomarker. 95 patients and 60 controls were enrolled from the University Psychiatry Unit of Catania and from general practitioners (GPs). The patients were divided into four pathological groups: Anxiety, Depression, Anxious-Depressive Disorder and Eating Disorders [Diagnostic and Statistical Manual of Mental Disorders Fourth Edition Text Revision (DSM-IV-TR) official/appendix criteria]. The levels of the cholesterol, triglycerides and apolipoproteins A and B were determined. The LI, for each subject, was obtained through a mathematical operation on the values of the cholesterol and triglycerides levels compared with the maximum cut-off of the general population. The autonomic functioning was tested with Ewing battery tests. Particularly, the correlation between heart rate variability (HRV) and lipid metabolism has been investigated. Pathological and control groups, compared among each other, presented some peculiarities in the lipid metabolism and the autonomic dysfunction scores. In addition, a statistically significant correlation has been found between HRV and lipid metabolism. Lipid metabolism and autonomic functioning seem to be related to the discussed psychiatric disorders. LI, in addition, could represent a new possible biomarker to be considered.

Burke, Jeffrey D; Loeber, Rolf

2016-01-01

Evidence for effective treatment for behavioral problems continues to grow, yet evidence about the effective mechanisms underlying those interventions has lagged behind. The Stop Now and Plan (SNAP) program is a multicomponent intervention for boys between 6 and 11. This study tested putative treatment mechanisms using data from 252 boys in a randomized controlled trial of SNAP versus treatment as usual. SNAP includes a 3 month group treatment period followed by individualized intervention, which persisted through the 15 month study period. Measures were administered in four waves: at baseline and at 3, 9 and 15 months after baseline. A hierarchical linear modeling strategy was used. SNAP was associated with improved problem-solving skills, prosocial behavior, emotion regulation skills, and reduced parental stress. Prosocial behavior, emotion regulation skills and reduced parental stress partially mediated improvements in child aggression. Improved emotion regulation skills partially mediated treatment-related child anxious-depressed outcomes. Improvements in parenting behaviors did not differ between treatment conditions. The results suggest that independent processes may drive affective and behavioral outcomes, with some specificity regarding the mechanisms related to differing treatment outcomes.

The present study explored the role of parents' in-session and out-session involvement in CBT for anxious children. Fifty 8- to 12-year-old children with a principal DSM-IV anxiety disorder participated in a group CBT program. Parental involvement in the therapy was assessed by the clinician and the children and parents completed a standardized anxiety scale as the main therapy outcome measure, at pre- and post-intervention. In addition, the parents completed questionnaires to evaluate a number of possible correlates of parental involvement, namely, child's anxiety symptoms intensity and interference, parental beliefs about anxiety, expectancies regarding the efficacy of the intervention, and parental anxiety. The results indicated that the parents were moderately involved in the therapy and that socio-economic status and parental beliefs about anxiety were significant correlates of parental involvement. Finally, partial support was found for the idea that parents' involvement in the therapy might have a positive impact on therapy outcome.

The behavior of rats irradiated with a sublethal single dose of γ-rays on the region of head in open field test

Smajda, B.; Kiskova, J.; Kereskenyiova, E.

2004-01-01

The goal of this work was to establish the effects of the irradiation of head in laboratory rats on some forms of naturalistic behavior in the open field test. During a 5-day control period behavioral parameters reflecting motory and explorative activity, as well as anxiousness of animals (6 parameters in total) were followed daily in 20 male Sprague-Dowley rats in an open field test lasting 5 minutes. Fourteen animals were repeatedly tested after irradiation of head with a single dose of 10 Gy of gamma rays. The results showed statistically significant depression of motory and explorative activities during the first 3 days after irradiation in comparison with the control period. The anxiousness of animals was decreased, too. Novelty habituation was observed only in non-irradiated animals. Based on these results it is possible to presume, that the applied dose of ionizing radiation was able to influence the brain centers involved in control of naturalistic behavioral functions connected with response to new environment in rats.

Sex differences in depressive, anxious behaviors and hippocampal transcript levels in a genetic rat model.

Major depressive disorder (MDD) is a common, debilitating illness with high prevalence of comorbid anxiety. The incidence of depression and of comorbid anxiety is much higher in women than in men. These gender biases appear after puberty and their etiology is mostly unknown. Selective breeding of the Wistar Kyoto (WKY) rat strain, an accepted model of adult and adolescent depression, resulted in two fully inbred substrains. Adult WKY more immobile (WMI) rats of both sexes consistently show increased depression-like behavior in the forced swim test when compared with the control WKY less immobile (WLI) strain. In contrast, here we show that while adult female WMIs and WLIs both display high anxiety-like behaviors, only WLI males, but not WMI males, show this behavior. Moreover, the behavioral profile of WMI males is consistent from early adolescence to adulthood, but the high depression- and anxiety-like behaviors of the female WMIs appear only in adulthood. These sex-specific behavioral patterns are paralleled by marked sex differences in hippocampal gene expression differences established by genome-wide transcriptional analyses of 13th generation WMIs and WLIs. Moreover, sex- and age-specific differences in transcript levels of selected genes are present in the hippocampus of the current, fully inbred WMIs and WLIs. Thus, the contribution of specific genes and/or the influence of the gonadal hormonal environment to depression- and anxiety-like behaviors may differ between male and female WMIs, resulting in their distinct behavioral and transcriptomic profiles despite shared sequences of the somatic chromosomes. © 2013 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

The role of anxiety sensitivity in the relation between anxious arousal and cannabis and alcohol use problems among low-income inner city racial/ethnic minorities.

The current study explored anxiety sensitivity as a factor accounting for the association between anxious arousal and problems related to use of cannabis and alcohol among a health disparity sample (low income minorities). Specifically, participants were 130 low-income racial/ethnic minorities who reported daily cannabis use (M age =37.7 SD=10.0; 28.5% female). There were significant indirect associations of anxious arousal via anxiety sensitivity in relation to: cannabis use problems, cannabis withdrawal symptoms, use of cannabis to cope, as well as hazardous drinking, alcohol use problems, and alcohol consumption. These data indicate anxiety sensitivity is a possible mechanism underlying the relation between anxious arousal and substance use problems among low-income racial/ethnic minorities. Future work could evaluate the efficacy of cannabis and alcohol use treatments incorporating anxiety sensitivity reduction techniques to facilitate amelioration of anxiety and substance use and offset mental health inequalities for this population.

2016-01-01

To explore the characteristics of brain function recovery in patients after prolonged posttraumatic coma and with long-unconscious states. Eighty-seven patients after prolonged posttraumatic coma were followed-up for two years. An analysis of a clinical/neurological picture after a prolonged episode of coma was based on the dynamics of vital functions, neurological status and patient's reactions to external stimuli. Based on the dynamics of the clinical/neurological picture that shows the recovery of functions of the certain brain areas, three stages of brain function recovery after a prolonged episode of coma were singled out: brain stem areas, diencephalic areas and telencephalic areas. These functional/anatomic areas of brain function recovery after prolonged coma were compared to the present classifications.

[Pathophysiology of prolonged hypokinesia].

Science.gov (United States)

Kovalenko, E A

1976-01-01

Hypokinesia is an important problem in modern medicine. In the pathogenetic effect of prolonged hypokinesia the main etiological factor is diminished motor activity; of major importance are disorders in the energy and plastic metabolism which affect the muscle system; the contributing factors are cardiovascular deconditioning and orthostatic intolerance. This is attributed to a decreased oxygen supply and eliminated hydrostatic influences during a prolonged recumbency. Blood redistribution in the vascular bed is related to the Gauer-Henry reflex and subsequent changes in the fluid-electrolyte balance. Decreased load on the bone system induces changes in the protein-phosphate-calcium metabolism, diminished bone density and increased calcium content in the blood and urine. Changes in the calcium metabolism are systemic. The activity of the higher nervous system and reflex functions is lowered. Changes in the function of the autonomic nervous system which include a noticeable decline of its adaptive-trophic role as a result of the decrease of afferent and efferent impulsation are of great importance. Changes in the hormonal function involve a peculiar stress-reaction which develops at an early stage of hypokinesia as a response to an unusual situation. Prolonged hypokinesia may result in a disturbed function of the pituitary-adrenal system. It is assumed that prolonged hypokinesia may induce a specific disease of hypokinesia during which man cannot lead a normal mode of life and work.

It is generally recognized that the AIDS epidemic will have a negative effect on the orphans’ school education. However, few studies have been carried out to examine the school performance and school behavior of AIDS orphans and vulnerable children (children living with HIV-infected parents). Using both self-report and teacher evaluation data of 1625 children from rural central China, we examined the impact of parental HIV/AIDS on children's school performances (academic marks, educational expectation, and student leadership) and school behaviors (e.g., aggression, shy/anxious and assertive social skills). Results indicate that AIDS orphans and vulnerable children had disadvantages in school performances in comparison to their peers from the same community who did not experience AIDS-related death and illness in their family (comparison children). AIDS orphans had the lowest academic marks based on the reports of both children and teachers. Educational expectation was significantly lower among AIDS orphans and vulnerable children than comparison children from teacher's perspective. AIDS orphans were significantly more likely to demonstrate aggressive, impulsive and anxious behaviors than non-orphans. Moreover, orphans have more learning difficulties. Vulnerable children were also at a disadvantage on most measures. The data suggest that a greater attention is needed to the school performance and behavior of children affected by AIDS. The findings also indicate that AIDS relief and assistance program for children should go beyond the school attendance and make efforts to improve their school performance and education aspiration.

2017-01-01

Full Text Available Hyperthyroidism is a highly prevalent disease affecting over 4 million people in the US. The disease is associated with many cardiac complications including atrial fibrillation and also less commonly with ventricular tachycardia and fibrillation. Many cardiac pathologies have been extensively studied; however, the relationship between hyperthyroidism and rate of ventricular repolarization manifesting as a prolonged QTc interval is not well known. Prolonged QTc interval regardless of thyroid status is a risk factor for cardiovascular mortality and life-threatening ventricular arrhythmia. The mechanism regarding the prolongation of the QT interval in a hyperthyroid patient has not been extensively investigated although its clinical implications are relevant. Herein, we describe a case of prolonged QTc in a patient who presented with signs of hyperthyroidism that was corrected with return to euthyroid status.

Predictors of math achievement in attention-deficit/hyperactivity disorder (ADHD) are not well-known. To address this gap in the literature, we examined individual differences in neurocognitive functioning domains on math computation in a cross-sectional sample of youth with ADHD. Gender and anxiety symptoms were explored as potential moderators. The sample consisted of 281 youth (aged 8-15 years) diagnosed with ADHD. Neurocognitive tasks assessed auditory-verbal working memory, visuospatial working memory, and processing speed. Auditory-verbal working memory speed significantly predicted math computation. A three-way interaction revealed that at low levels of anxious perfectionism, slower processing speed predicted poorer math computation for boys compared to girls. These findings indicate the uniquely predictive values of auditory-verbal working memory and processing speed on math computation, and their differential moderation. These findings provide preliminary support that gender and anxious perfectionism may influence the relationship between neurocognitive functioning and academic achievement.

A field investigation of flight anxiety: Evidence of gender differences in consumer behaviors among Las Vegas passengers

Lindsey A Harvell

2016-02-01

Full Text Available Purpose: This study examines how anxious the Las Vegas public is through a case study of one local international airport. Design/Methodology/Approach: This study examines gender differences in consumer behaviors among the flying public inside Las Vegas McCarran International Airport in a field experiment theoretically grounded in Terror Management Theory. Findings and Originality/Value: Because airports are replete with reminders of human mortality, it is not a surprise that death awareness and flight anxiety may be closely related. The flying public that is anxious to fly presents an interesting public relations situation for airports. Therefore, this study examines how anxious the Las Vegas public is through a case study of one local international airport. Results show that flight anxiety does provoke the same kind of existential defenses that traditional death awareness does. This study also suggests that men and women do not react to flight anxiety in a uniform way, they are different in their reactions in seeking to gamble, eating unhealthy food, and an increased desire for electronic entertainment.

Full Text Available Complaints of fatigue and physical exhaustion are frequently seen in the acute medical setting, especially amongst athletes, army recruits and persons involved in strenuous and exertional physical activities. Stress-induced exhaustion, on the other hand, is less often seen, but can present with very similar symptoms to physical exhaustion. Recently, three patients were seen at the Department of Emergency Medicine, presenting with exhaustion from prolonged involvement in gambling activities. The cases serve to highlight some of the physical consequences of prolonged gambling.

The problem of prolongation of nuclear power plant service life duration is discussed. A schematic diagram of the program developed in the course of activities dealing with NPP service time prolongation is shown and analyzed in details. It is shown that the basic moment when determining the strategy for NPP service time prolongation is the positive confirmation of the agreement between the NPP safety provisions and modern safety requirements. The other very important aspect of the problem is engineering substantiation of the measures assuring the reactor operation prolongation. The conclusion is made that available methods of recovering reactor materials properties, main components repair and replacement, the modern techniques for nondestructive testing of metals and NPP pipelines, as well as the developed approaches to reactor facility safety improvements make the prolongation of the Russian NPP service lifetimes possible from engineering viewpoint and economically desirable

Is the link between posttraumatic growth and anxious symptoms mediated by marital intimacy in breast cancer patients?

Canavarro, Maria Cristina; Silva, Sónia; Moreira, Helena

2015-12-01

This study aimed to determine whether marital intimacy mediates the association between posttraumatic growth (PTG) and anxious symptoms in women who had recently completed breast cancer treatments and breast cancer survivors. Forty-eight patients who had completed their treatment six months prior to the study and 46 disease-free survivors who had completed their treatments at least one year prior to the study completed the Posttraumatic Growth Inventory, the Personal Assessment of Intimacy Scale, and the Hospital Anxiety and Depression Scale. Recently off-treatment patients reported higher levels of intimacy than survivors did. Path analyses showed that higher levels of the Appreciation of Life dimension of PTG were associated with less anxious symptoms through higher levels of marital intimacy. The type of group did not moderate these associations. Regardless of the disease phase, the experience of positive changes after breast cancer in terms of an enhanced appreciation of life seems to be associated with an increased perception of intimacy in the context of a dyadic relationship, which, in turn, is associated with less anxiety.

Kiel, Elizabeth J.; Maack, Danielle J.

Although sensitivity to the Behavioral Inhibition System within Gray’s (1970) reinforcement sensitivity theory relates to individuals’ own depressive and anxious symptomatology, less is known about how parental BIS sensitivity relates to early indicators of internalizing problems in young children. Moreover, the extent to which this parental characteristic relates to parenting behavior, and children’s internalizing problems above and beyond parenting, remains unknown. The current study assessed maternal BIS sensitivity, overprotective parenting, and toddlers’ internalizing behaviors in a sample of 91 mothers while controlling for mothers’ own internalizing symptomatology. Heightened BIS sensitivity related to both overprotective parenting and internalizing behaviors. Overprotective parenting partially mediated the relation between BIS sensitivity and children’s internalizing behaviors, although BIS sensitivity maintained a marginal relation to internalizing behaviors. Maternal BIS sensitivity and toddler internalizing behaviors may represent a shared disposition towards inhibition that is somewhat accounted for by overprotective parenting. PMID:22904590

Chen, Junwen; McLean, Jordan E; Kemps, Eva

2018-03-01

This study investigated the effects of combined audience feedback with video feedback plus cognitive preparation, and cognitive review (enabling deeper processing of feedback) on state anxiety and self-perceptions including perception of performance and perceived probability of negative evaluation in socially anxious individuals during a speech performance. One hundred and forty socially anxious students were randomly assigned to four conditions: Cognitive Preparation + Video Feedback + Audience Feedback + Cognitive Review (CP+VF+AF+CR), Cognitive Preparation + Video Feedback + Cognitive Review (CP+VF+CR), Cognitive Preparation + Video Feedback only (CP+VF), and Control. They were asked to deliver two impromptu speeches that were evaluated by confederates. Participants' levels of anxiety and self-perceptions pertaining to the speech task were assessed before and after feedback, and after the second speech. Compared to participants in the other conditions, participants in the CP+VF+AF+CR condition reported a significant decrease in their state anxiety and perceived probability of negative evaluation scores, and a significant increase in their positive perception of speech performance from before to after the feedback. These effects generalized to the second speech. Our results suggest that adding audience feedback to video feedback plus cognitive preparation and cognitive review may improve the effects of existing video feedback procedures in reducing anxiety symptoms and distorted self-representations in socially anxious individuals.

Inhibition of spontaneous recovery of fear by mGluR5 after prolonged extinction training.

Directory of Open Access Journals (Sweden)

Sheng-Chun Mao

Full Text Available Fear behavior is vital for survival and involves learning contingent associations of non-threatening cues with aversive stimuli. In contrast, excessive levels of fear can be maladaptive and lead to anxiety disorders. Generally, extensive sessions of extinction training correlates with reduced spontaneous recovery. The molecular mechanisms underlying the long-term inhibition of fear recovery following repeated extinction training are not fully understood. Here we show that in rats, prolonged extinction training causes greater reduction in both fear-potentiated startle and spontaneous recovery. This effect was specifically blocked by metabotropic glutamate receptor 5 (mGluR5, but not by mGluR1 antagonists and by a protein synthesis inhibitor. Similar inhibition of memory recovery following prolonged extinction training was also observed in mice. In agreement with the instrumental role of mGluR5 in the prolonged inhibition of fear recovery, we found that FMR1-/- mice which exhibit enhanced mGluR5-mediated signaling exhibit lower spontaneous recovery of fear after extinction training than wild-type littermates. At the molecular level, we discovered that prolonged extinction training reversed the fear conditioning-induced increase in surface expression of GluR1, AMPA/NMDA ratio, postsynaptic density-95 (PSD-95 and synapse-associated protein-97 (SAP97. Accordingly, delivery of Tat-GluR2(3Y, a synthetic peptide that blocks AMPA receptor endocytosis, inhibited prolonged extinction training-induced inhibition of fear recovery. Together, our results demonstrate that prolonged extinction training results in the mGluR5-dependent long-term inhibition of fear recovery. This effect may involve the degradation of original memory and may explain the beneficial effects of prolonged exposure therapy for the treatment of phobias.

Cancer anorexia–cachexia syndrome is characterized by decreased food intake, weight loss, muscle tissue wasting and psychological distress, and this syndrome is a major source of increased morbidity and mortality in cancer patients. This study aimed to clarify the gut–brain peptides involved in the pathogenesis of the syndrome and determine effective treatment for cancer anorexia–cachexia. We show that both ghrelin insufficiency and resistance were observed in tumor-bearing rats. Corticotropin-releasing factor (CRF) decreased the plasma level of acyl ghrelin, and its receptor antagonist, α-helical CRF, increased food intake of these rats. The serotonin 2c receptor (5-HT2cR) antagonist SB242084 decreased hypothalamic CRF level and improved anorexia, gastrointestinal (GI) dysmotility and body weight loss. The ghrelin receptor antagonist (D-Lys3)-GHRP-6 worsened anorexia and hastened death in tumor-bearing rats. Ghrelin attenuated anorexia–cachexia in the short term, but failed to prolong survival, as did SB242084 administration. In addition, the herbal medicine rikkunshito improved anorexia, GI dysmotility, muscle wasting, and anxiety-related behavior and prolonged survival in animals and patients with cancer. The appetite-stimulating effect of rikkunshito was blocked by (D-Lys3)-GHRP-6. Active components of rikkunshito, hesperidin and atractylodin, potentiated ghrelin secretion and receptor signaling, respectively, and atractylodin prolonged survival in tumor-bearing rats. Our study demonstrates that the integrated mechanism underlying cancer anorexia–cachexia involves lowered ghrelin signaling due to excessive hypothalamic interactions of 5-HT with CRF through the 5-HT2cR. Potentiation of ghrelin receptor signaling may be an attractive treatment for anorexia, muscle wasting and prolong survival in patients with cancer anorexia–cachexia. PMID:22832525

The aim of this study was to design and optimize a prolonged release matrix formulation of pyridostigmine bromide, an effective drug in myasthenia gravis and poisoning with nerve gas, using hydrophilic - hydrophobic polymers via D-optimal experimental design. HPMC and carnauba wax as retarding agents as well as tricalcium phosphate were used in matrix formulation and considered as independent variables. Tablets were prepared by wet granulation technique and the percentage of drug released at 1 (Y(1)), 4 (Y(2)) and 8 (Y(3)) hours were considered as dependent variables (responses) in this investigation. These experimental responses were best fitted for the cubic, cubic and linear models, respectively. The optimal formulation obtained in this study, consisted of 12.8 % HPMC, 24.4 % carnauba wax and 26.7 % tricalcium phosphate, had a suitable prolonged release behavior followed by Higuchi model in which observed and predicted values were very close. The study revealed that D-optimal design could facilitate the optimization of prolonged release matrix tablet containing pyridostigmine bromide. Accelerated stability studies confirmed that the optimized formulation remains unchanged after exposing in stability conditions for six months.

The relationship between enterprise size and psychosocial working conditions has received little attention so far but some findings suggest that they are more favorable in small enterprises. This could have a positive impact on workers' mental health. The objective of this study was to test the mediating effect of perceived working conditions in the relationship between enterprise size and anxious or depressive episodes. Data from the 2010 SUMER French periodical cross-sectional survey was analyzed (N=31 420 for the present study). Anxious or depressive episodes were measured with the hospital anxiety and depression scale (HAD) and perceived working conditions were psychological demand, decision latitude and social support as assessed with Karasek's job content questionnaire (JCQ). The indirect effect was tested according to the method proposed by Preacher and Hayes (2008). In a multivariate logistic regression, the risk of anxious or depressive episodes was found to be lower in micro-enterprises (2-9 employees). Formal tests pointed to a significant indirect effect of enterprise size on mental health through perceived working conditions, with a larger effect for psychological demand. Conclusion This study highlights perceived working conditions as an explanation of the effects of enterprise size.

Anxiety and depressive symptoms are common in childhood, however problems in need of intervention may not be identified. Children at risk for developing more severe problems can be identified based on elevated symptom levels. Quality of life and self-esteem are important functional domains and may provide additional valuable information. Schoolchildren (n = 915), aged 9-13, who considered themselves to be more anxious or sad than their peers, completed self-reports of anxiety (Multidimensional Anxiety Scale for children (MASC-C), depression (The Short Mood and Feelings Questionnaire; SMFQ), quality of life (Kinder Lebensqualität Fragebogen; KINDL) and self-esteem (Beck self-concept inventory for youth (BSCI-Y) at baseline of a randomized controlled indicative study. Using multivariate analyses, we examined the relationships between internalizing symptoms, quality of life and self-esteem in three at-risk symptom groups. We also examined gender and age differences. 52.1 % of the screened children scored above the defined at-risk level reporting elevated symptoms of either Anxiety and Depression (Combined group) (26.6 %), Depression only (15.4 %) or Anxiety only (10.2 %). One-way ANOVA analysis showed significant mean differences between the symptom groups on self-reported quality of life and self-esteem. Regression analysis predicting quality of life and self-esteem showed that in the Depression only group and the Combined group, symptom levels were significantly associated with lower self-reported scores on both functional domains. In the Combined group, older children reported lower quality of life and self-esteem than younger children. Internalizing symptoms explained more of the variance in quality of life than in self-esteem. Symptoms of depression explained more of the variance than anxious symptoms. Female gender was associated with higher levels of internalizing symptoms, but there was no gender difference in quality of life and self

Emotional, behavioural, and health benefits of gentle stroking and vocalizations, otherwise known as gentling, have been documented for several species, but little is known about the effect of gentling on cats in stressful situations. In this study, 139 cats rated as anxious upon admission to an animal shelter were allocated to either a Gentled or Control group. Cats were gentled four times daily for 10 min over a period of 10 days, with the aid of a tool for cats that were too aggressive to handle. The cats' mood, or persistent emotional state, was rated daily for 10 d as Anxious, Frustrated or Content. Gentled cats were less likely to have negatively valenced moods (Anxious or Frustrated) than Control cats (Incidence Rate Ratio [IRR]=0.61 CI 0.42-0.88, P=0.007). Total secretory immunoglobulin A (S-IgA) was quantified from faeces by enzyme-linked immunosorbent assay. Gentled cats had increased S-IgA (6.9 ± 0.7 logeμg/g) compared to Control cats (5.9 ± 0.5 logeμg/g) (Pincrease in shedding over time in Control cats (23%, 35%, 52% on days 1, 4 and 10, respectively), but not in gentled cats (32%, 26%, 30% on days 1, 4 and 10, respectively) (P=0.001). Onset of upper respiratory disease was determined by veterinary staff based on clinical signs, in particular ocular and/or nasal discharge. Control cats were 2.4 (CI: 1.35-4.15) times more likely to develop upper respiratory disease over time than gentled cats (Pincrease production of S-IgA, and reduce the incidence of upper respiratory disease.

The contribution of rib fractures to prolonged pain and disability may be underappreciated and undertreated. Clinicians are traditionally taught that the pain and disability of rib fractures resolves in 6 to 8 weeks. This study was a prospective observation of 203 patients with rib fractures at a level 1 trauma center. Chest wall pain was evaluated by the McGill Pain Questionnaire (MPQ) pain rating index (PRI) and present pain intensity (PPI). Prolonged pain was defined as a PRI of 8 or more at 2 months after injury. Prolonged disability was defined as a decrease in 1 or more levels of work or functional status at 2 months after injury. Predictors of prolonged pain and disability were determined by multivariate analysis. One hundred forty-five male patients and 58 female patients with a mean injury severity score (ISS) of 20 (range, 1 to 59) had a mean of 5.4 rib fractures (range, 1 to 29). Forty-four (22%) patients had bilateral fractures, 15 (7%) had flail chest, and 92 (45%) had associated injury. One hundred eighty-seven patients were followed 2 months or more. One hundred ten (59%) patients had prolonged chest wall pain and 142 (76%) had prolonged disability. Among 111 patients with isolated rib fractures, 67 (64%) had prolonged chest wall pain and 69 (66%) had prolonged disability. MPQ PPI was predictive of prolonged pain (odds ratio [OR], 1.8; 95% confidence interval [CI], 1.4 to 2.5), and prolonged disability (OR, 2.2; 95% CI, 1.5 to 3.4). The presence of significant associated injuries was predictive of prolonged disability (OR, 5.9; 95% CI, 1.4 to 29). Prolonged chest wall pain is common, and the contribution of rib fractures to disability is greater than traditionally expected. Further investigation into more effective therapies that prevent prolonged pain and disability after rib fractures is needed. Copyright © 2013 Elsevier Inc. All rights reserved.

Morphological adaptations in breast cancer cells as a function of prolonged passaging on compliant substrates.

Directory of Open Access Journals (Sweden)

Sana Syed

Full Text Available Standard tissue culture practices involve propagating cells on tissue culture polystyrene (TCP dishes, which are flat, 2-dimensional (2D and orders of magnitude stiffer than most tissues in the body. Such simplified conditions lead to phenotypical cell changes and altered cell behaviors. Hence, much research has been focused on developing novel biomaterials and culture conditions that more closely emulate in vivo cell microenvironments. In particular, biomaterial stiffness has emerged as a key property that greatly affects cell behaviors such as adhesion, morphology, proliferation and motility among others. Here we ask whether cells that have been conditioned to TCP, would still show significant dependence on substrate stiffness if they are first pre-adapted to a more physiologically relevant environment. We used two commonly utilized breast cancer cell lines, namely MDA-MB-231 and MCF-7, and examined the effect of prolonged cell culturing on polyacrylamide substrates of varying compliance. We followed changes in cell adhesion, proliferation, shape factor, spreading area and spreading rate. After pre-adaptation, we noted diminished differences in cell behaviors when comparing between soft (1 kPa and stiff (103 kPa gels as well as rigid TCP control. Prolonged culturing of cells on complaint substrates further influenced responses of pre-adapted cells when transferred back to TCP. Our results have implications for the study of stiffness-dependent cell behaviors and indicate that cell pre-adaptation to the substrate needs consideration.

Aims To investigate a possible association of sibutramine with QT interval prolongation. Methods Post-marketing surveillance using prescription event monitoring in the New Zealand Intensive Medicines Monitoring Programme (IMMP) identified a case of QT prolongation and associated cardiac arrest in a patient taking sibutramine for 25 days. This patient was further investigated, including genotyping for long QT syndrome. Other IMMP case reports suggesting arrhythmias associated with sibutramine were assessed and further reports were obtained from the World Health Organisation (WHO) adverse drug reactions database. Results The index case displayed a novel mutation in a cardiac potassium channel subunit gene, KCNQ1, which is likely to prolong cardiac membrane depolarization and increase susceptibility to long QT intervals. Assessment of further IMMP reports identified five additional patients who experienced palpitations associated with syncope or presyncopal symptoms, one of whom had a QTc at the upper limit of normal. Assessment of reports from the WHO database identified three reports of QT prolongation and one fatal case of torsade de pointes in a patient also taking cisapride. Conclusions This case series suggests that sibutramine may be associated with QT prolongation and related dysrhythmias. Further studies are required, but in the meantime we would recommend that sibutramine should be avoided in patients with long QT syndrome and in patients taking other medicines that may prolong the QT interval.

Núñez-Peña, M Isabel; Tubau, Elisabet; Suárez-Pellicioni, Macarena

2017-06-01

The aim of the study was to investigate how high math-anxious (HMA) individuals react to errors in an arithmetic task. Twenty HMA and 19 low math-anxious (LMA) individuals were presented with a multi-digit addition verification task and were given response feedback. Post-error adjustment measures (response time and accuracy) were analyzed in order to study differences between groups when faced with errors in an arithmetical task. Results showed that both HMA and LMA individuals were slower to respond following an error than following a correct answer. However, post-error accuracy effects emerged only for the HMA group, showing that they were also less accurate after having committed an error than after giving the right answer. Importantly, these differences were observed only when individuals needed to repeat the same response given in the previous trial. These results suggest that, for HMA individuals, errors caused reactive inhibition of the erroneous response, facilitating performance if the next problem required the alternative response but hampering it if the response was the same. This stronger reaction to errors could be a factor contributing to the difficulties that HMA individuals experience in learning math and doing math tasks. Copyright © 2017 Elsevier B.V.

Poor Illness Perceptions Are a Risk Factor for Depressive and Anxious Symptomatology in Fibromyalgia Syndrome: A Longitudinal Cohort Study

Directory of Open Access Journals (Sweden)

2017-11-01

Full Text Available BackgroundPatients with widespread pain, such as in fibromyalgia, are vulnerable for depression and anxiety, which composes a relevant public health problem. Identifying risk factors for the onset of depression and anxiety is therefore warranted. Objective of this study was to determine whether severe pain, maladaptive coping, and poor illness perceptions are associated with depressive and anxious symptomatology in fibromyalgia.MethodConsecutive patients referred to an outpatient clinic completed sets of physical and psychological questionnaires at baseline and at 18-month follow-up. A total of 452 patients with fibromyalgia syndrome (FMS were eligible for inclusion, and subsequently, 280 patients returned the baseline questionnaire. Depressive and anxious symptomatology was measured with the Hospital Anxiety and Depression Scale. To measure pain severity, coping style, and illness perceptions, the Fibromyalgia Impact Questionnaire, Pain Coping Inventory, and the Illness Perception Questionnaire-Revised (IPQ-R were used, respectively. Multivariable logistic regression analyses, bootstrapping and calibration, were performed to examine the association of pain severity, pain coping, and illness perception with depressive and anxiety symptoms at follow-up, adjusted for sociodemographic variables. Initial level of depressive and anxiety symptoms was selected as covariates.ResultsMean age was 42.6 years and 95.4% were female. At 18-month follow-up, 68 (of the 195 patients were depressed and 80 (of the 197 were anxious. Only the IPQ-R subscale “emotional representations” showed a significant positive association with depressive symptoms at follow-up (OR = 1.10, next to the initial level of depressive symptoms (OR = 1.30. In case of anxiety, only the IPQ-R subscale “treatment control” showed a significant negative association with anxiety symptoms at follow-up (OR = 0.87, next to the initial level of anxiety symptoms (OR = 1

Conclusions: The present results extend our understanding of the development of problematic use of Internet communicative services, based on the framework of the dual factor model of Facebook use and the Self Determination Theory. The fulfillment of an unmet need for self-presentation (i.e. the desire to create a positive impression of one's self in others through SNSs could be one of the possible pathways to GPIU for socially anxious males.

Efficacy of bupropion and the selective serotonin reuptake inhibitors in the treatment of major depressive disorder with high levels of anxiety (anxious depression): a pooled analysis of 10 studies.

The goal of this work was to compare the efficacy of the norepinephrine and dopamine reuptake inhibitor bupropion with the selective serotonin reuptake inhibitors (SSRIs) in the treatment of major depressive disorder with high levels of anxiety (anxious depression). Ten double-blind, randomized studies from 1991 through 2006 were combined (N = 2122). Anxious depression was defined as a 17-item Hamilton Rating Scale for Depression (HAM-D-17) anxiety-somatization factor score >or= 7. Among patients with anxious depression (N = 1275), response rates were greater following SSRI than bupropion treatment according to the HAM-D-17 (65.4% vs. 59.4%, p = .03) and the Hamilton Rating Scale for Anxiety (61.5% vs. 54.5%, p = .03). There was also a greater reduction in HAM-D-17 mean +/- SD scores (-14.1 +/- 7.6 vs. -13.2 +/- 7.9, p = .03) and a trend toward statistical significance for a greater reduction in HAM-A mean +/- SD scores (-10.5 +/- 7.4 vs. -9.6 +/- 7.6, p = .05) in favor of SSRI treatment among patients with anxious depression. There was no statistically significant difference in efficacy between bupropion and the SSRIs among patients with moderate/low levels of anxiety. There appears to be a modest advantage for the SSRIs compared to bupropion in the treatment of anxious depression (6% difference in response rates). Using the number-needed-to-treat (NNT) statistic as 1 indicator of clinical significance, nearly 17 patients would need to be treated with an SSRI than with bupropion in order to obtain 1 additional responder. This difference falls well above the limit of NNT = 10, which was suggested by the United Kingdom's National Institute of Clinical Excellence. Nevertheless, the present work is of theoretical interest because it provides preliminary evidence suggesting a central role for serotonin in the regulation of symptoms of negative affect such as anxiety.

The current study compared the predicted social and career impact of socially withdrawn and reticent behaviors among participants from Western and East Asian countries. Three hundred sixty-one college students from 5 Western countries and 455 students from 3 East Asian countries read hypothetical vignettes describing socially withdrawn and shy behaviors versus socially outgoing and confident behaviors. Participants then answered questions following each vignette indicating the extent to which they would expect the subject of the vignette to be socially liked and to succeed in their career. Participants also completed measures of their own social anxiety and quality of life. The results indicated significant vignette-by-country interactions in that the difference in perceived social and career impact between shy and outgoing vignettes was smaller among participants from East Asian countries than from Western countries. In addition, significant negative correlations were shown between personal level of shyness and experienced quality of life for participants from both groups of countries, but the size of this relationship was greater for participants from Western than East Asian countries. The results point to the more negative impact of withdrawn and socially reticent behaviors for people from Western countries relative to those from East Asia. Copyright © 2011.

Previous studies with temozolomide suggest that a prolonged duration of chemotherapy is important for treating low-grade gliomas (LGGs). PCV (procarbazine, CCNU, vincristine) chemotherapy has demonstrated efficacy in treating LGGs, but this therapy cannot be used for a prolonged period because of the cumulative toxicity. The aim of the present study was to evaluate the impact of first-line PCV chemotherapy on LGGs growth kinetics. The mean tumor diameter (MTD) of 21 LGGs was measured on serial magnetic resonance images before (n=13), during, and after PCV onset (n=21). During PCV treatment, a decrease in the MTD was observed in all patients. After PCV discontinuation, an ongoing decrease in MTD was observed in 20 of the 21 patients. Median duration of the MTD decrease was 3.4 years (range, 0.8–7.7) after PCV onset and 2.7 years (range, 0–7) after the end of PCV treatment with 60% of LGGs, demonstrating an ongoing and prolonged (>2 years) response despite chemotherapy no longer being administered. According to McDonald's criteria, the rates of partial and minor responses were 5% and 38% at the end of PCV but 38% and 42% at the time of maximal MTD decrease, which occurred after a median period of 3.4 years after PCV onset. These results challenge the idea that a prolonged duration of chemotherapy is necessary for treating LGGs and raise the issue of understanding the mechanisms involved in the persistent tumor volume decrease once chemotherapy is terminated.

Does UTI cause prolonged jaundice in otherwise well infants?

Science.gov (United States)

Chowdhury, Tanzila; Kisat, Hamudi; Tullus, Kjell

2015-07-01

The symptoms of urinary tract infections in infants are very non-specific and have historically included prolonged hyperbilirubinaemia. We studied the results of routine urine samples in 319 infants with prolonged jaundice. Convincing findings of UTI was not found in any of these children even if one of them was treated with antibiotics after four consecutive urine cultures with different bacteria. A urine culture might thus not be an appropriate investigation in a child with prolonged jaundice without any other symptoms of UTI. • The symptoms of UTI in infancy are very non-specific. • Old studies suggest that prolonged hyperbilirubinaemia is one such symptom; more modern studies give more conflicting results. What is New: • Our study could not confirm that children with prolonged jaundice have an increased risk of UTI. • Routine urine testing is thus not needed in otherwise healthy infants with prolonged jaundice.

Beyond anxious predisposition: do padecer de nervios and ataque de nervios add incremental validity to predictions of current distress among Mexican mothers?

Science.gov (United States)

Alcántara, Carmela; Abelson, James L; Gone, Joseph P

2012-01-01

Nervios (PNRV) and ataque de nervios (ATQ) are culture-bound syndromes with overlapping symptoms of anxiety, depression, and dissociation, shown to have inconsistent associations to psychiatric disorder. Few studies test the basic assumption that PNRV and ATQ are uniformly linked to distress outcomes across Latina/o immigrant groups. This study examined: (a) the extent to which acculturative stress, Latino/US American acculturation, and anxious predisposition were associated with lifetime history of ATQ and PNRV, and (b) the extent to which ATQ and PNRV add incremental validity in explaining acculturative stress and psychological distress beyond measures of anxious predisposition. Participants (n = 82) included Mexican mothers who completed surveys on acculturation, trait anxiety, anxiety sensitivity, lifetime ATQ/PNRV, psychological distress, and acculturative stress. Lifetime PNRV, but not lifetime ATQ, was significantly predictive of psychological distress. PNRV was also linked to trait anxiety. Psychometric measures of anxious predisposition (trait anxiety and anxiety sensitivity) were more robust predictors of distress outcomes than lifetime history of ATQ/PNRV. Inquiry into lifetime history of nervios may be a useful point of entry in talking to Mexican immigrant mothers about stress and distress. However, standard tools for assessing anxiety sensitivity and trait anxiety appear most useful in identifying and explaining the presence of psychological distress. Further research is needed to determine the cross-cultural relevance of trait anxiety and anxiety sensitivity, and its implications for the development of anxiety treatments that are effective across cultures. © 2011 Wiley-Liss, Inc.

Prolonged striatal disinhibition as a chronic animal model of tic disorders.

Science.gov (United States)

Vinner, Esther; Israelashvili, Michal; Bar-Gad, Izhar

2017-12-01

Experimental findings and theoretical models have associated Tourette syndrome with abnormal striatal inhibition. The expression of tics, the hallmark symptom of this disorder, has been transiently induced in non-human primates and rodents by the injection of GABA A antagonists into the striatum, leading to temporary disinhibition. The novel chronic model of tic expression utilizes mini-osmotic pumps implanted subcutaneously in the rat's back for prolonged infusion of bicuculline into the dorsolateral striatum. Tics were expressed on the contralateral side to the infusion over a period of multiple days. Tic expression was stable, and maintained similar properties throughout the infusion period. Electrophysiological recordings revealed the existence of tic-related local field potential spikes and individual neuron activity changes that remained stable throughout the infusion period. The striatal disinhibition model provides a unique combination of face validity (tic expression) and construct validity (abnormal striatal inhibition) but is limited to sub-hour periods. The new chronic model extends the period of tic expression to multiple days and thus enables the study of tic dynamics and the effects of behavior and pharmacological agents on tic expression. The chronic model provides similar behavioral and neuronal correlates of tics as the acute striatal disinhibition model but over prolonged periods of time, thus providing a unique, basal ganglia initiated model of tic expression. Chronic expression of symptoms is the key to studying the time varying properties of Tourette syndrome and the effects of multiple internal and external factors on this disorder.

Dunifon, Rachel; Kalil, Ariel; Crosby, Danielle A; Su, Jessica Houston

2013-10-01

Many mothers work in jobs with nonstandard schedules (i.e., schedules that involve work outside of the traditional 9-5, Monday through Friday schedule); this is particularly true for economically disadvantaged mothers. In the present article, we used longitudinal data from the Fragile Families and Child Wellbeing Survey (n = 2,367 mothers of children ages 3-5 years) to examine the associations between maternal nonstandard work and children's behavior problems, with a particular focus on mothers' night shift work. We employed 3 analytic strategies with various approaches to adjusting for observed and unobserved selection factors; these approaches provided an upper and lower bound on the true relationship between night shift work and children's behavior. Taken together, the results provide suggestive evidence for modest associations between exposure to maternal night shift work and higher levels of aggressive and anxious or depressed behavior in children compared with children whose mothers who are not working, those whose mothers work other types of nonstandard shifts, and, for aggressive behavior, those whose mothers work standard shifts.

Mazer-Amirshahi, Maryann; Porter, Robert; Dewey, Kayla

2018-05-05

Aripiprazole is an atypical antipsychotic with a long half-life. Overdose can result in protracted somnolence and cardiac disturbances, particularly QT interval prolongation. This is a single case report of a 14-year-old boy who took an overdose of aripiprazole and developed QRS widening. A 14-year-old boy intentionally ingested 20 tablets of aripiprazole (5 mg). He was brought to the emergency department when his ingestion was discovered. The patient's vital signs were as follows: temperature, 37.7°C; heart rate, 108 beats/min; blood pressure, 138/98 mm Hg; and respirations, 16 breaths/min. Activated charcoal was administered within 90 minutes of ingestion. Initial electrocardiogram (EKG) showed sinus tachycardia, with a QRS of 138 ms and QT interval of 444 ms. QRS duration was 90 ms on an EKG performed 3 months earlier. A bolus of sodium bicarbonate was administered, and the patient was transferred to the pediatric intensive care unit. Repeat EKG demonstrated a QRS of 156 ms, and a sodium bicarbonate infusion was initiated. The patient continued to have QRS prolongation for the next 8 days, reaching a peak of 172 ms 3 days postingestion. Despite aggressive treatment with sodium bicarbonate, there was persistent QRS prolongation; however, the patient did not have any dysrhythmias and remained hemodynamically stable. The patient was discharged 9 days postingestion when the QRS duration normalized to 82 ms. Genetic testing revealed that the patient was a CYP2D6 poor metabolizer. This case suggests that aripiprazole toxicity may possibly be associated with QRS prolongation without associated dysrhythmias or cardiovascular compromise. In addition, toxicity may be prolonged in patients who are CYP2D6 poor metabolizers.

Intergenerational Transmission of Internalizing Behavior: The Role of Maternal Psychopathology, Child Responsiveness and Maternal Attachment Style Insecurity.

Reck, Corinna; Nonnenmacher, Nora; Zietlow, Anna-Lena

Maternal depression and anxiety disorders are risk factors for the development of internalizing disorders in offspring. Maternal attachment has been discussed as one factor accounting for transmission. The aim of this study was to investigate child internalizing behavior at preschool age on a symptomatic and behavioral level and possible links to maternal mental health over time and maternal attachment style insecurity in a sample of postpartum depressed and anxious mothers. Child internalizing behavior at preschool age was rated by the Child Behavior Checklist (CBCL), the Caregiver-Teacher Report Form (C-TRF), and during a mother-child free-play situation. We focused on child responsiveness as it has been linked to child internalizing behavior. Maternal attachment style insecurity was tested to mediate the link between maternal mental health (assessed postpartum and at preschool age with the Structured Clinical Interview for DSM-IV Axis-I Disorders, SCID-I) and child internalizing behavior/child responsiveness. Of the overall sample (n = 58), 28 women were diagnosed with postpartum depression and/or anxiety disorders according to DSM-IV, and 30 were healthy controls. Data were collected 3-9 months after delivery and at preschool age (mean = 4.6 years). At preschool age, children of postpartum depressed and anxious mothers were rated significantly higher on child internalizing behavior by mothers, fathers, and additional caregivers compared to the control group. Child internalizing behavior rated by mothers was influenced by current psychiatric symptoms; maternal attachment style insecurity did not mediate this link. During interaction, children in the clinical group displayed significantly less child responsiveness compared to the control group. Maternal attachment style insecurity mediated the relationship between maternal mental health over time and child responsiveness. The results emphasize the need for interventions focusing on mother-child interaction and

The present study aimed to investigate how online and offline social behavior interact with each other ultimately to affect the well-being of socially anxious adolescents. Based on previous studies, it was assumed that there might be three-way interactive effects among online social behavior, offline social behavior, and social anxiety regarding the relationship with well-being. To measure social anxiety, online and offline social behavior, and mental well-being, self-report questionnaires such as the Korean-Social Avoidance and Distress Scale, Korean version of the Relational Maintenance Behavior Questionnaire, and Korean version of Mental Health Continuum Short Form were administered to 656 Korean adolescents. Hierarchical regression analysis revealed that the three-way interaction of online social behavior, offline social behavior, and social anxiety was indeed significant. First, online social behavior was associated with lower well-being of adolescents with higher social anxiety under conditions of low engagement in offline social behavior. In contrast, a higher level of online social behavior predicted greater well-being for individuals with high social anxiety under conditions of more engagement in offline social behavior. Second, online social behavior was not significantly related to well-being in youths with low social anxiety under conditions of both high and low engagement in offline social behavior. Implications and limitations of this study were discussed.

Cannabis Use Behaviors and Social Anxiety: The Roles of Perceived Descriptive and Injunctive Social Norms

Ecker, Anthony H.; Buckner, Julia D.

2014-01-01

Objective: Individuals with greater social anxiety are particularly vulnerable to cannabis-related impairment. Descriptive norms (beliefs about others’ use) and injunctive norms (beliefs regarding others’ approval of risky use) may be particularly relevant to cannabis-related behaviors among socially anxious persons if they use cannabis for fear of evaluation for deviating from what they believe to be normative behaviors. Yet, little research has examined the impact of these social norms on the relationships between social anxiety and cannabis use behaviors. Method: The current study investigated whether the relationships of social anxiety to cannabis use and use-related problems varied as a function of social norms. The sample comprised 230 (63.0% female) current cannabis-using undergraduates. Results: Injunctive norms (regarding parents, not friends) moderated the relationship between social anxiety and cannabis-related problem severity. Post hoc probing indicated that among participants with higher (but not lower) social anxiety, those with greater norm endorsement reported the most severe impairment. Injunctive norms (parents) also moderated the relationship between social anxiety and cannabis use frequency such that those with higher social anxiety and lower norm endorsement used cannabis less frequently. Descriptive norms did not moderate the relationship between social anxiety and cannabis use frequency. Conclusions: Socially anxious cannabis users appear to be especially influenced by beliefs regarding parents’ approval of risky cannabis use. Results underscore the importance of considering reference groups and the specific types of norms in understanding factors related to cannabis use behaviors among this vulnerable population.

Becoming Therapeutic Agents: A Grounded Theory of Mothers' Process When Implementing Cognitive Behavioural Therapy at Home with an Anxious Child.

Science.gov (United States)

Pishva, Rana

2017-05-01

The premise of parent-centred programmes for parents of anxious children is to educate and train caregivers in the sustainable implementation of cognitive behaviour therapy (CBT) in the home. The existing operationalization of parent involvement, however, does not address the systemic, parent or child factors that could influence this process. The qualitative approach of grounded theory was employed to examine patterns of action and interaction involved in the complex process of carrying out CBT with one's child in one's home. A grounded theory goes beyond the description of a process, offering an explanatory theory that brings taken-for-granted meanings and processes to the surface. The theory that emerged from the analysis suggests that CBT implementation by mothers of anxious children is characterized by the evolution of mothers' perception of their child and mothers' perception of their role as well as a shift from reacting with emotion to responding pragmatically to the child. Changes occur as mothers recognize the crisis, make links between the treatment rationale, child's symptoms and their own parenting strategies, integrate tenets of CBT for anxiety and eventually focus on sustaining therapeutic gains through natural life transitions. The theory widens our understanding of mothers' role, therapeutic engagement, process, and decision-making. The theory also generates new hypotheses regarding parent involvement in the treatment of paediatric anxiety disorders and proposes novel research avenues that aim to maximize the benefits of parental involvement in the treatment of paediatric anxiety disorders. Copyright © 2016 John Wiley & Sons, Ltd. Mothers of anxious youth who take part in parent-centred programmes experience a shift in their perception of the child and of their role. Parental strategy after CBT implementation shifts from emotional empathy to cognitive empathy. Mothers experience significant challenges and require additional support in prevention

This study was conducted to investigate the association between prolonged breastfeeding and early childhood caries(ECC) with adjustment for important confounders, using hieraschical approach. This retrospective cohort study involved 260 low-income children (18-42 months). The number of decayed teeth was used as a measure of caries. Following a theoretical framework, the hierarchical model was built in a forward fashion, by adding the following levels in succession: level 1: age; level 2: social variables; level 3: health variables; level 4: behavioral variables; level 5: oral hygiene-related variables; level 6: oral hygiene quality measured by visible plaque; and level 7: contamination by mutans streptococci. Sequential forward multiple Poisson regression analysis was employed. Breast-feeding was not a risk factor for ECC after adjustment for some confounders (incidence density ratio, 1.15; 95% confidence interval, 0.84-1.59, P = 0.363). Prolonged breast-feeding was not a risk factor for ECC while age, high sucrose comption between main meals and the quality of oral higiene were associated with disease in children. © 2012 John Wiley & Sons A/S.

Short-Term Total Sleep-Deprivation Impairs Contextual Fear Memory, and Contextual Fear-Conditioning Reduces REM Sleep in Moderately Anxious Swiss Mice

Full Text Available The conditioning tasks have been widely used to model fear and anxiety and to study their association with sleep. Many reports suggest that sleep plays a vital role in the consolidation of fear memory. Studies have also demonstrated that fear-conditioning influences sleep differently in mice strains having a low or high anxiety level. It is, therefore, necessary to know, how sleep influences fear-conditioning and how fear-conditioning induces changes in sleep architecture in moderate anxious strains. We have used Swiss mice, a moderate anxious strain, to study the effects of: (i sleep deprivation on contextual fear conditioned memory, and also (ii contextual fear conditioning on sleep architecture. Animals were divided into three groups: (a non-sleep deprived (NSD; (b stress control (SC; and (c sleep-deprived (SD groups. The SD animals were SD for 5 h soon after training. We found that the NSD and SC animals showed 60.57% and 58.12% freezing on the testing day, while SD animals showed significantly less freezing (17.13% only; p < 0.001 on the testing day. Further, we observed that contextual fear-conditioning did not alter the total amount of wakefulness and non-rapid eye movement (NREM sleep. REM sleep, however, significantly decreased in NSD and SC animals on the training and testing days. Interestingly, REM sleep did not decrease in the SD animals on the testing day. Our results suggest that short-term sleep deprivation impairs fear memory in moderate anxious mice. It also suggests that NREM sleep, but not REM sleep, may have an obligatory role in memory consolidation.

Recent models propose deoxyribonucleic acid methylation of key neuro-regulatory genes as a molecular mechanism underlying the increased risk of mental disorder associated with early life adversity (ELA). The goal of this study was to examine the association of ELA with oxytocin receptor gene (OXTR) methylation among young adults. Drawing from a 21-year longitudinal cohort, we compared adulthood OXTR methylation frequency of 46 adults (23 males and 23 females) selected for high or low ELA exposure based on childhood socioeconomic status and exposure to physical and sexual abuse during childhood and adolescence. Associations between OXTR methylation and teacher-rated childhood trajectories of anxiousness were also assessed. ELA exposure was associated with one significant CpG site in the first intron among females, but not among males. Similarly, childhood trajectories of anxiousness were related to one significant CpG site within the promoter region among females, but not among males. This study suggests that females might be more sensitive to the impact of ELA on OXTR methylation than males.

2015-08-01

There is a high rate of comorbidity between borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD; Pagura et al., 2010). Preliminary studies have evaluated the treatment of PTSD in a BPD population and found positive outcomes for the integration of dialectical behavior therapy (DBT) and prolonged exposure (PE). This case study illustrates the implementation of a PE protocol into standard DBT treatment, specifically focusing on the management of self-harm and severe dissociation for a client with co-occurring PTSD and BPD. The client entered into treatment with severe and persistent dissociation and a recent history of self-harm, and the case includes consideration of two separate pauses in PTSD treatment related to elevated dissociation and self-harm behaviors. The client successfully completed the DBT PE protocol and results indicate significant improvements in PTSD symptoms as well as outcomes related to self-harm and dissociation. These findings demonstrate the efficacy of combining DBT with PE for clients with comorbid BPD and PTSD and exemplify how complex clients with BPD who present with severe dissociation and self-harm behavior can safely and successfully receive treatment for PTSD. © 2015 Wiley Periodicals, Inc.

Hardaway, Cecily R; Larkby, Cynthia A; Cornelius, Marie D

2014-07-01

This study examines whether exposure to community violence is indirectly related to academic performance through anxious/depressed symptoms and delinquent behaviors. Three hundred eighteen mothers and adolescents who participated in a longitudinal investigation were interviewed when adolescents were age 10, 14, and 16. Community violence exposure at age 14 was significantly related to anxious/depressed symptoms and delinquent behaviors. Delinquent behaviors (but not anxious/depressed symptoms) were significantly associated with academic performance at age 16. Exposure to community violence was indirectly related to academic performance through delinquent behaviors. There was no significant indirect effect of exposure to community violence on academic performance through anxious/depressed symptoms. Covariates included sociodemographics and exposure to child abuse. Age 10 anxious/depressed symptoms, age 10 delinquent behaviors, and age 14 academic performance were also included in the model to control for preexisting differences in socioemotional adjustment and academic performance. Results suggest that exposure to community violence may initiate a cascade of problems that spread from behavior problems to declines in academic performance. Our results highlight the need for schools to consider exposure to community violence as one form of trauma and to transform in ways that make them more trauma-sensitive. The use of trauma-sensitive practices that address the effects of violence exposure on youth may help limit the progression of adverse effects from delinquent behavior to other domains of functioning.

This study describes prevalence of depressive and anxious symptoms together with family, environmental and personal risk factors in a group of adolescents between 14 and 18 years of age in a private school of Medellín. An analytic observational cross sectional study was performed in 152 adolescents, evaluating sociodemographic aspects and prevalence of depressive and anxious symptomatology, as established through BDI-II and BAI. Average age was 15.4 ± 0.9 years old, with a 25% prevalence of anxiety symptoms and 25.7% of depressive symptoms. From the 38 (25%) students with BAI positive, 26 (68.4%) were BDI positive, and from the 39 (25.6%) students with BDI positive, 26 (66.7%) were BAI positive. the risk factors for anxiety and depressive symptomatology were: being a woman, being a victim of bullying and abuse. Having friends was the protective factors for depressive symptomatology. There was a statistical association between self-report of depressive and anxiety symptomatology; between the anxiety self-report and the depressive symptomatology; as well as between depressive and anxiety symptomatology and parents' perception of such symptoms.

Protocols for measuring attentional bias to threat in test-anxiety, a special form of trait-anxiety, are rarely found in the literature. In our eye-tracking study, we introduced a new protocol, and studied the time-course of attention to test-related pictures with varying threat levels in 22 high test-anxious (HTA) and 22 low test-anxious (LTA) subjects. To determine whether attentional bias to test-related pictures is due to test-anxiety and not to state-anxiety, we also included a third group of 22 subjects with high state-anxiety but low test-anxiety (HSA). The subjects completed a free viewing task (FVT) in which high threat-neutral (HT-N) and low threat-neutral (LT-N) picture pairs were presented for 3 s. The results demonstrated that: (1) HTA subjects showed initial orienting to LT pictures, early attentional engagement with HT pictures later on and avoidance of HT pictures at the very end; (2) LTA subjects showed initial orienting to HT pictures and maintenance of attention on them later on; while (3) HSA subjects showed an initial orientation towards LT pictures and maintenance of attention on LT and HT pictures later on. These results suggest that, (high) test-anxiety is also prone to attentional bias towards test-related threat stimuli. Implications for future research are discussed.

Information concerning 36 indicators of aberrant behavior of the children were supplied by their parents, whereas their cognitive ability was tested by Raven’s progressive colored matrices. Based on factor analysis (promax method, four factors i.e. generators of aberrant behavior in children were singled out: aggression, anxiousness, dissociation, and hysteria, whose relations with cognitive functioning and age were also analyzed by factor analysis. Aberrant behavior and cognitive abilities show significant interrelatedness. Owing to orderly developed cognitive abilities, a child understands essence and reality of problems, realizes possibilities and manners of solving them, and succeeds in realizing successful psycho-social functioning. Developed cognitive abilities enable a child to recognize and understand her/his own reactions in different situations and develop manners of reacting, which leads to strengthening psycho-social safety and adapting behavior in accordance with her/his age and abilities.

Many mothers work in jobs with nonstandard schedules (i.e., schedules that involve work outside of the traditional 9–5, Monday through Friday schedule); this is particularly true for economically disadvantaged mothers. The present paper uses longitudinal data from the Fragile Families and Child Wellbeing Survey (n = 2,367 mothers of children ages 3–5) to examine the associations between maternal nonstandard work and children’s behavior problems, with a particular focus on mothers’ night shift work. We employ three analytic strategies that take various approaches to adjusting for observed and unobserved selection factors; these approaches provide an upper and lower bound on the true relationship between night shift work and children’s behavior. Taken together, the results provide suggestive evidence for modest associations between exposure to maternal night shift work and higher levels of aggressive and anxious/depressed behavior in children compared to mothers who are not working, those whose mothers work other types of nonstandard shifts, and, for aggressive behavior, those whose mothers work standard shifts.

Escalation of anxious behavior while environmentally and socially relevant contextual events amplify the intensity of emotional response produces a testable gradient of anxiety shaped by integrative circuitries. Apprehension of the Stress-Alternatives Model apparatus (SAM) oval open field (OF) is measured by the active latency to escape, and is delayed by unfamiliarity with the passageway. Familiar OF escape is the least anxious behavior along the continuum, which can be reduced by anxiolytics such as icv neuropeptide S (NPS). Social aggression increases anxiousness in the SAM, reducing the number of mice willing to escape by 50%. The apprehension accompanying escape during social aggression is diminished by anxiolytics, such as exercise and corticotropin releasing-factor receptor 1 (CRF1) antagonism, but exacerbated by anxiogenic treatment, like antagonism of α2-adrenoreceptors. What is more, the anxiolytic CRF1 and anxiogenic α2-adrenoreceptor antagonists also modify behavioral phenotypes, with CRF1 antagonism allowing escape by previously submissive animals, and α2-adrenoreceptor antagonism hindering escape in mice that previously engaged in it. Gene expression of NPS and brain-derived neurotrophic factor (BDNF) in the central amygdala (CeA), as well as corticosterone secretion, increased concomitantly with the escalating anxious content of the mouse-specific anxiety continuum. The general trend of CeA NPS and BDNF expression suggested that NPS production was promoted by increasing anxiousness, and that BDNF synthesis was associated with learning about ever-more anxious conditions. The intensity gradient for anxious behavior resulting from varying contextual conditions may yield an improved conceptualization of the complexity of mechanisms producing the natural continuum of human anxious conditions, and potential therapies that arise therefrom.

Gere, Martina K; Villabø, Marianne A; Torgersen, Svenn; Kendall, Philip C

2012-08-01

The relationship between overprotective parenting and child anxiety has been examined repeatedly because theories emphasize its role in the maintenance of child anxiety. No study has yet tested whether this relationship is unique to child anxiety, by controlling for commonly co-occurring behavior problems within the same children. The current study examined 190 children (age 7-13, 118 [corrected] boys) referred to mental health clinics and their parents. Results revealed that significant correlations between overprotective parenting and child anxiety symptoms disappear after controlling for co-occurring child behavior symptoms. It appears that overprotection is not uniquely related to child anxiety. Furthermore, overprotective parenting was significantly and uniquely related to child behavior symptoms. Researchers and practitioners need to consider co-occurring child behavior problems when working with the parents of anxious children. Copyright © 2012 Elsevier Ltd. All rights reserved.

Pharmacometabolomic approach to predict QT prolongation in guinea pigs.

Directory of Open Access Journals (Sweden)

Jeonghyeon Park

Full Text Available Drug-induced torsades de pointes (TdP, a life-threatening arrhythmia associated with prolongation of the QT interval, has been a significant reason for withdrawal of several medicines from the market. Prolongation of the QT interval is considered as the best biomarker for predicting the torsadogenic risk of a new chemical entity. Because of the difficulty assessing the risk for TdP during drug development, we evaluated the metabolic phenotype for predicting QT prolongation induced by sparfloxacin, and elucidated the metabolic pathway related to the QT prolongation. We performed electrocardiography analysis and liquid chromatography-mass spectroscopy-based metabolic profiling of plasma samples obtained from 15 guinea pigs after administration of sparfloxacin at doses of 33.3, 100, and 300 mg/kg. Principal component analysis and partial least squares modelling were conducted to select the metabolites that substantially contributed to the prediction of QT prolongation. QTc increased significantly with increasing dose (r = 0.93. From the PLS analysis, the key metabolites that showed the highest variable importance in the projection values (>1.5 were selected, identified, and used to determine the metabolic network. In particular, cytidine-5'-diphosphate (CDP, deoxycorticosterone, L-aspartic acid and stearic acid were found to be final metabolomic phenotypes for the prediction of QT prolongation. Metabolomic phenotypes for predicting drug-induced QT prolongation of sparfloxacin were developed and can be applied to cardiac toxicity screening of other drugs. In addition, this integrative pharmacometabolomic approach would serve as a good tool for predicting pharmacodynamic or toxicological effects caused by changes in dose.

Cognitive correlates of anxious and depressive symptomatology: an examination of the Helplessness/Hopelessness model.

Waikar, S V; Craske, M G

1997-01-01

Expectancies about future life events were assessed in anxious and depressed patients to test predictions of the Helplessness/Hopelessness model of anxiety and depression (Alloy, Kelly, Mineka, & Clements, 1990). In addition to expectancies for future events, patients from affective and anxiety treatment clinics completed anxiety and depression symptom ratings and positive and negative affects scales. Findings revealed partial support for the model. Negative outcome and helplessness expectancies were related specifically to depression. Cognitions regarding future positive events were interrelated and associated with symptom measures more strongly than were cognitions regarding negative events. Additionally, positive affects was more strongly related to depression than to anxiety symptom ratings. Implications and limitations of these findings are discussed.

2017-01-01

Individuals high in rejection sensitivity (RS) are at risk for experiencing high levels of interpersonal distress, yet little is known about the interpersonal profiles associated with RS. This investigation examined the interpersonal problems, sensitivities, and values associated with RS in 2 samples: 763 multicultural undergraduate students (Study 1) and 365 community adults (Study 2). In Study 1, high anxious RS was associated with socially avoidant interpersonal problems, whereas low anxious RS was associated with vindictive interpersonal problems. In Study 2, we assessed both anxious and angry expectations of rejection. Circumplex profile analyses showed that the high anxious RS group reported socially avoidant interpersonal problems, sensitivities to remoteness in others, and valuing connections with others, whereas the high angry RS group reported vindictive interpersonal problems, sensitivities to submissiveness in others, and valuing detached interpersonal behavior. Low anxious RS was related to domineering interpersonal problems, sensitivity to attention-seeking behavior, and valuing detached interpersonal behavior, whereas low angry RS was related to submissive interpersonal problems, sensitivity to attention-seeking behavior, and valuing receiving approval from others. Overall, results suggest that there are distinct interpersonal profiles associated with varying levels and types of RS.

Risk Factors for Prolonged Treatment of Whiplash-Associated Disorders.

Full Text Available Whiplash-associated disorders (WAD are the most common injuries that are associated with car collisions in Japan and many Western countries. However, there is no clear evidence regarding the potential risk factors for poor recovery from WAD. Therefore, we used an online survey of the Japanese population to examine the association between potential risk factors and the persistence of symptoms in individuals with WAD.An online survey was completed by 127,956 participants, including 4,164 participants who had been involved in a traffic collision. A random sample of the collision participants (n = 1,698 were provided with a secondary questionnaire. From among the 974 (57.4% respondents to the secondary questionnaire, we selected 183 cases (intractable neck pain that was treated over a period of 6 months and 333 controls (minor neck pain that was treated within 3 months. Multivariable logistic regression analysis was used to evaluate the potential risk factors for prolonged treatment of WAD.Female sex, the severity of the collision, poor expectations of recovery, victim mentality, dizziness, numbness or pain in the arms, and lower back pain were associated with a poor recovery from WAD.In the present study, the baseline symptoms (dizziness, numbness or pain in the arms, and lower back pain had the strongest associations with prolonged treatment for WAD, although the psychological and behavioral factors were also important. These risk factors should be considered when evaluating patients who may have the potential for poor outcomes.

2012-06-01

This study focused on the development and pilot testing of a protocol based on Prolonged Exposure (PE) that can be added to Dialectical Behavior Therapy (DBT) to treat PTSD in suicidal and self-injuring individuals with borderline personality disorder (BPD). Women with BPD, PTSD, and recent and/or imminent serious intentional self-injury (n = 13) received one year of DBT with the DBT PE Protocol, plus three months of follow-up assessment. The treatment was associated with significant reductions in PTSD, with the majority of patients no longer meeting criteria for PTSD at post-treatment (71.4% of DBT PE Protocol completers, 60.0% of the intent-to-treat sample). A minority of patients (27.3%) engaged in intentional self-injury during the study. Improvements were also found for suicidal ideation, dissociation, trauma-related guilt cognitions, shame, anxiety, depression, and social adjustment. There was no evidence that the DBT PE Protocol led to exacerbations of intentional self-injury urges or behaviors, PTSD, treatment dropout, or crisis service use. Overall, the results indicate that this integrated BPD and PTSD treatment is feasible to implement within one year of treatment, highly acceptable to patients and therapists, safe to administer, and shows promise as an effective intervention for PTSD in this complex and high-risk patient population.

Prolonged screen time (ST), which includes TV viewing and gaming on smartphones and computers, is linked to poor health. Our aim was to explore the associations between school children with prolonged ST and parental internet use (IU) and lifestyles in Japan. Children aged 6 to 13 years from the Super Shokuiku School Project, were surveyed using questionnaires in 2016. The survey assessed the grade, sex, and lifestyle of 1,659 children and parental internet use (IU) and lifestyle using Breslow's seven health behaviors. IU consisted of internet surfing and gaming on personal computers (PC), smartphones, or consoles. Three or more hours of ST was defined as prolonged ST, and its correlates were analyzed using logistic regression. Of all, 643 (38.8%) children spent ≥2 hours/day of ST on a week day, whilst 153 (9.2%) children spent ≥3 hours/day. Prolonged ST was significantly associated with children in higher grade (odds ratio [OR] 1.74; 95% confidence interval [CI], 1.20-2.51), boys (OR 2.16; 95% CI, 1.49-3.14), skipping breakfast (OR 1.88; 95% CI, 1.05-3.35), late bedtime (OR 1.80; 95% CI, 1.15-2.82), physical inactivity (OR 1.79; 95% CI, 1.12-2.87), father's IU ≥2 hours/day (OR 2.35; 95% CI, 1.52-3.63), mother's prolonged IU ≥2 hours/day (OR 2.55; 95% CI, 1.43-4.52), mothers with unhealthy behaviors (OR 1.81; 95% CI, 1.05-3.13), no rule setting governing screen time (OR 2.41; 95% CI, 1.63-3.58), and mothers with full-time employment (OR 1.95; 95% CI, 1.06-3.64). Prolonged ST among Japanese children was strongly associated with parental IU, no set rules for ST, and mother's unhealthy lifestyles. To reduce children's ST, parental engagement is warranted in the intervention strategy.

We investigate the superprincipal bundle and its associated superbundle. The super(nonlinear)connection on the superfiber bundle is constructed. Then by means of the connection theory, we establish the fermionic covariant prolongation structure theory of the supernonlinear evolution equation. In this geometry theory, the fermionic covariant fundamental equations determining the prolongation structure are presented. As an example, the supernonlinear Schroedinger equation is analyzed in the framework of this fermionic covariant prolongation structure theory. We obtain its Lax pairs and Baecklund transformation.

Evaluating differences in Pavlovian fear acquisition and extinction as predictors of outcome from cognitive behavioural therapy for anxious children.

Science.gov (United States)

Waters, Allison M; Pine, Daniel S

2016-07-01

Extinction is a key theoretical model of exposure-based treatments, such as cognitive behavioural therapy (CBT). This study examined whether individual differences in physiological responses and subjective stimulus evaluations as indices of fear extinction predicted response to CBT. Thirty-two nonanxious comparisons and 44 anxious, 7-to-13-year-old children completed a Pavlovian conditioning and extinction task. Anxious children then completed group-based CBT. Skin conductance responses (SCRs) as well as subjective arousal and valence evaluations were measured in response to a conditioned stimulus paired with an aversive tone (CS+) and another conditioned stimulus presented alone (CS-). Both stimuli were presented alone during extinction. Diagnostic and symptom measures were completed before and after treatment. Like nonanxious comparisons, treatment responders did not acquire conditioned negative stimulus evaluations and displayed elevated SCRs that declined significantly across extinction trials. Nonresponders, by contrast, showed elevated negative stimulus evaluations of both CSs that were sensitive to extinction trials but showed no change in SCRs during extinction. Change in physiological but not evaluative indices of fear extinction predicted better treatment outcomes. Individual differences in evaluative and physiological indices of fear extinction might moderate response to CBT. © 2016 Association for Child and Adolescent Mental Health.

The current study examined differences in emotion expression identification between adolescents characterized with behavioral inhibition (BI) in childhood with and without a lifetime history of anxiety disorder. Participants were originally assessed for behavioral inhibition during toddlerhood and for social reticence during childhood. During adolescence, participants returned to the laboratory and completed a facial-emotion identification task and a clinical psychiatric interview. Results revealed that behaviorally inhibited adolescents with a lifetime history of anxiety disorder displayed a lower threshold for identifying fear relative to anger emotion expressions compared to non-anxious behaviorally inhibited adolescents and non-inhibited adolescents with or without anxiety. These findings were specific to behaviorally inhibited adolescents with a lifetime history of social anxiety disorder. Thus, adolescents with a history of both BI and anxiety, specifically social anxiety, are more likely to differ from other adolescents in their identification of fearful facial expressions. This offers further evidence that perturbations in the processing of emotional stimuli may underlie the etiology of anxiety disorders. PMID:24800906

Parental emotional distress, particularly high maternal anxiety, is one of the most consistent predictors of child anxiety treatment outcome. In order to identify the cognitive, affective, and behavioral parenting characteristics of mothers of children with anxiety disorders who themselves have an anxiety disorder, we assessed the expectations, appraisals, and behaviors of 88 mothers of anxious children (44 mothers who were not anxious [NONANX] and 44 mothers with a current anxiety disorder [ANX]) when interacting with their 7-12-year-old children. There were no observed differences in anxiety and avoidance among children of ANX and NONANX mothers, but, compared with NONANX mothers, ANX mothers held more negative expectations, and they differed on observations of intrusiveness, expressed anxiety, warmth, and the quality of the relationship. Associations were moderated by the degree to which children expressed anxiety during the tasks. Maternal-reported negative emotions during the task significantly mediated the association between maternal anxiety status and the observed quality of the relationship. These findings suggest that maternal anxiety disorder is associated with reduced tolerance of children's negative emotions. This may interfere with the maintenance of a positive, supportive mother-child interaction under conditions of stress and, as such, this may impede optimum treatment outcomes. The findings identify potential cognitive, affective, and behavioral targets to improve treatment outcomes for children with anxiety disorders in the context of a current maternal anxiety disorder. 2013 APA, all rights reserved

Iqbal, S.

2004-01-01

Objective: To compare two strategies for management of prolonged pregnancy (= or >294 days) i.e. induction (intervention) versus expectant management (non-intervention) and evaluate the associated feto-maternal risks. Subjects and Methods: One hundred cases of uncomplicated prolonged gestation were selected. The gestational age was confirmed by ultrasound in first trimester. One group (50 patients) was managed by intervention i.e. induction of labour (group A) and other group (50 patients) by non-intervention i.e. expectant management (group B). In group A intervention was done at 42 weeks. In expectant group, the methods of monitoring were fetal kick charting recorded daily by the patient, and ultrasound for amniotic fluid index. The biophysical profile score and NST (non stress test) were performed once a week till 42 weeks and then twice weekly. Results: The frequency of prolonged pregnancy was found to be 10.9%. There was no significant difference in the number of spontaneous vaginal deliveries between the two groups. The rate of LSCS (lower segment caesarean section) was higher in intervention group ( 30% versus 18% ). The neonatal depression at birth was more in group B ( 10% versus 4%) and at 5 minutes almost same between two groups (4% versus 2%). There were 11 cases of meconium aspiration syndrome, leading to one neonatal death. Among nine perinatal deaths two were neonatal deaths. Seven cases of intrauterine deaths in which antepartum deaths occurred because of non compliance of patients. No cause could be detected for the other three fetuses. Conclusion: There was increased LSCS rate in group A. However in expectant group B perinatal mortality was about twice more as compared to intervention group. Active early intervention at 42 weeks is warranted to reduce perinatal morbidity and mortality. (author)

Are Pressure Vests Beneficial at Reducing Stress in Anxious and Fearful Dogs?

Full Text Available PICO questionIn fearful or anxious dogs does wearing a pressure vest, compared to not wearing one, result in reduced behavioural and physiological signs of stress? Clinical bottom lineFour studies of variable quality and limitations were identified that investigated the use of pressure vests, using various physiological and behavioural proxy measures of anxiety. Most behavioural outcome measures associated with a positive effect were subjective assessments, with unblinded assessors. Subjectively, many of the owners believed that pressure vests had a positive effect on their dogs’ anxiety levels.The take home message for the veterinary professional is that pressure vests may have small but beneficial effects on canine anxiety click to tweet and that habituating the dog to the vest, assessing for comfort and using repeatedly may improve the likelihood of any benefit. However, the owner should be cautioned that they should not expect their dog’s anxiety to be fully alleviated or prevented, and it may have no beneficial effect at all. 

Listening to Birds in the Anthropocene: The Anxious Semiotics of Sound in a Human-Dominated World

Directory of Open Access Journals (Sweden)

Whitehouse, Andrew

2015-05-01

Full Text Available Ever since Rachel Carson predicted a “silent spring” environmentalists have been carefully and anxiously listening to birds. More recently the musician and scientist Bernie Krause has examined the effects of human activity on avian soundscapes throughout the world. He argues that human activities cause ecological and sonic disruptions that really are rendering the world silent or discordant, submerging the “animal orchestra” beneath noise. A healthy natural environment can be heard, according to Krause, in a rich and harmonious soundscape that has evolved over millions of years. The loss of wildness thus elicits a loss of harmony. I consider these Anthropocene interpretations of silence, noise and dissonance by comparing the environmentalist concerns of Krause with responses to the Listening to Birds project—an anthropological investigation of bird sounds. These responses emphasise the significance of bird sounds for people’s sense of place, time and season and the longing that many have for their own lives to resonate with the birds around them. I argue that this has less to do with desires to hear harmony in pristine nature but with developing relations of companionship with birds living alongside humans. While listening to birds can still iconically and indexically ground people, signs of absence and change can precipitate anxieties that stem from the ambiguities implicit in the Anthropocene’s formulation of human relations with other species. Using narratives and field recordings I explore the anxious semiotics of listening to birds in the Anthropocene by drawing on Kohn’s recent arguments on the semiotics of more-than-human relations and Ingold’s understanding of the world as a meshwork.

Objective: To determine the effect of a 50-km trail race on salivary cortisol (Cort, IgA, Lys, and Lac. Methods: 14 subjects: (6 females, 8 males completed a 50km ultramarathon. Saliva was collected pre, immediately after (post and 1.5 hrs post race ( 1.5. Results: Lac concentration was higher at 1.5 hrs post race compared to post exercise (p0.05. IgA concentration, secretion rate, and IgA/Osm were lower 1.5 hrs post compared to pre race (p<0.05. Cort concentration was higher at post compared to 1.5 (p<0.05, but was unaltered from pre race levels. Subjects finished in 7.81 ± 1.2 hrs. Saliva flow rate did not differ between time points. Saliva Osm increased at post (p<0.05 compared to pre race. Conclusions: The intensity could have been too low to alter Lys and Lac secretion rates and thus, may not be as sensitive as IgA to changes in response to prolonged running. Results expand our understanding of the mucosal immune system and may have implications for predicting illness after prolonged running.

In 2012, the Food and Drug Administration issued Drug Safety Communications on several drugs associated with QT prolongation and fatal ventricular arrhythmias. Among these was citalopram, a selective serotonin reuptake inhibitor (SSRI) approved for depression and commonly used for posttraumatic stress disorder (PTSD). Evaluation of the risk for QT prolongation among other psychotropic drugs for individuals with PTSD remains limited. Explore psychotropic drugs associated with QT prolongation among veterans with PTSD. Patients in the Veterans Health Administration in 2006-2009 with PTSD and QT prolongation (176 cases) were matched 1:4 on age, gender, visit date and setting, and physical comorbidity. Classification trees assessed QT prolongation risk among prescribed medications (n=880). Receipt of any drug with known risk of QT prolongation varied by group (23% QT cases vs 15% control, prisks included ziprasidone (3% vs 1%, p=0.02) and buspirone (6% vs 2%, p=0.01). Increased risk was not observed for the SSRIs, citalopram and fluoxetine. Classification trees found that sotalol and amitriptyline carried greater risk among cardiac patients and methadone, especially if prescribed with quetiapine, among noncardiac patients. Per adjusted survival model, patients with QT prolongation were at increased risk for death (hazard ratio=1.60; 95% CI=1.04-2.44). Decision models are particularly advantageous when exploring nonlinear relationships or nonadditive interactions. These findings may potentially affect clinical decision-making concerning treatment for PTSD. For patients at higher risk of QT prolongation, antidepressants other than amitriptyline should be considered. Medications for comorbid conditions should also be closely monitored for heightened QT prolongation risk.

How do relationships support parenting? Effects of attachment style and social support on parenting behavior in an at-risk population.

The importance of supportive relationships for new parents has been the focus of both research and parenting interventions. Attachment style, typically viewed as a relatively stable trait reflecting one's comfort in social relationships, as well as social support, or one's perception of the social context, have both been found to be important for fostering engaged, involved parenting. Less is known, however, about how these variables work together to influence parenting behavior, especially in families at higher risk for negative child outcomes. Data were collected from 152 urban, predominantly African American, low-income parents when their children were 14 and 36 months of age. Results suggest that parents with more social support show greater increases in the frequency of positive parent-child activities over time, but that this effect is mediated by mothers' attachment style, specifically, their level of anxious/ambivalent attachment. Mothers with more social support tended to be less anxious/ambivalent about close relationships, and this in turn led to increases over time in the frequency of parent-child interactions. Mothers' tendency to avoid close relationships, however, while correlated with social support, was unrelated to changes in parenting behavior. Implications of these findings for program development, parenting, and the malleability of attachment style based on social context are discussed.

Full Text Available Dengue fever is gaining importance in Singapore with an increase in the number of cases and mortality in recent years. Although prolonged and saddleback fever have been reported in dengue fever, there are no specific studies on their significance in dengue. This study aims to examine the prevalence of prolonged and saddleback fever in dengue as well as their associations with dengue severity. A total of 2843 polymerase-chain reaction (PCR confirmed dengue patients admitted to Tan Tock Seng Hospital from 2004 to 2008 were included in the study. Sixty-nine percent of them were male with a median age of 34 years. Prolonged fever (fever > 7 days duration was present in 572 (20.1% of patients. Dengue hemorrhagic fever (DHF, dengue shock syndrome (DSS and severe dengue (SD were significantly more likely to occur in patients with prolonged fever. Mucosal bleeding, anorexia, diarrhea, abdominal pain, nausea or vomiting, lethargy, rash, clinical fluid accumulation, hepatomegaly, nosocomial infection, leukopenia, higher neutrophil count, higher hematocrit, higher alanine transaminase (ALT and aspartate transaminase (AST, higher creatinine, lower protein and prolonged activated partial thromboplastin time (APTT were significantly associated with prolonged fever but not platelet count or prothrombin time (PT. Saddleback fever was present in 165 (5.8%. Although DHF and SD were more likely to occur in patients in those with saddleback fever, DSS was not. Compared with prolonged fever, saddleback fever did not show many significant associations except for diarrhea, abdominal pain, clinical fluid accumulation, hematocrit and platelet change, and lower systolic blood pressure. This study demonstrates that prolonged fever may be associated with various warning signs and more severe forms of dengue (SD, DSS, DHF, while saddleback fever showed associations with DHF and SD but not DSS. The presence of prolonged or saddleback fever in dengue patients should therefore

The Japanese term hikikomori means literally 'to be confined'. Social withdrawal can be present in severe psychiatric disorders; however, in Japan, hikikomori is a defined nosologic entity. There have been only a few reported cases in occidental culture. We present a case report of a Spanish man with prolonged social withdrawal lasting for 4 years. This is a case of prolonged social withdrawal not bound to culture, as well as the second case of hikikomori reported in Spain. We propose prolonged social withdrawal disorder as a disorder not linked to culture, in contrast to hikikomori. Further documentation of this disorder is still needed to encompass all cases reported in Japan and around the world. © The Author(s) 2013.

2013-12-09

In Japan, people are negative towards life-prolonging treatments. Laws that regulate withholding or discontinuing life-prolonging treatments and advance directives do not exist. Physicians, however, view discontinuing life-prolonging treatments negatively due to fears of police investigations. Although ministerial guidelines were announced regarding the decision process for end-of-life care in 2007, a consensus could not be reached on the definition of end-of-life and conditions for withholding treatment. We established a forum for extended discussions and consensus building on this topic. We used the Neo-Socratic Dialogue (NSD) method which promotes philosophical discussion based on a case-study to address a question and formulate a consensus and answer in a group. The question chosen for the dialogue was: "What is a life-prolonging treatment?" A series of dialogues took place over a period of one and a half days. It was carried out by three groups in 2010 and 2011. Seven participants with diverse backgrounds were recruited per group. We analyzed the content of the discussion. Based on three case studies concerning different opinions about treatment options for an older dementia patient, a patient demanding chemotherapy, and a severely ill neonate, conditions for futile life-prolonging treatment were elucidated through NSD. Such treatments are those carried out for the sole purpose of prolonging life and are detrimental to the patient, and should be decided based foremost on the patient's lack of desire for treatment, the consensus of those involved, and through social acceptance. These arguments are essentially consistent with ones on medical futility in the United States. By expressing the objective of healthcare and the requirement of social acceptance, participants were also able to elucidate issues related to the awareness of those involved and the medical environment. Compared to the end-of-life guidelines in Japan, the objective of treatment, its effects

2014-01-01

Background When atrial fibrillation (AF) is incessant, imaging during a prolonged ventricular RR interval may improve image quality. It was hypothesized that long RR intervals could be predicted from preceding RR values. Methods From the PhysioNet database, electrocardiogram RR intervals were obtained from 74 persistent AF patients. An RR interval lengthened by at least 250 ms beyond the immediately preceding RR interval (termed T0 and T1, respectively) was considered prolonged. A two-parameter scatterplot was used to predict the occurrence of a prolonged interval T0. The scatterplot parameters were: (1) RR variability (RRv) estimated as the average second derivative from 10 previous pairs of RR differences, T13–T2, and (2) Tm–T1, the difference between Tm, the mean from T13 to T2, and T1. For each patient, scatterplots were constructed using preliminary data from the first hour. The ranges of parameters 1 and 2 were adjusted to maximize the proportion of prolonged RR intervals within range. These constraints were used for prediction of prolonged RR in test data collected during the second hour. Results The mean prolonged event was 1.0 seconds in duration. Actual prolonged events were identified with a mean positive predictive value (PPV) of 80% in the test set. PPV was >80% in 36 of 74 patients. An average of 10.8 prolonged RR intervals per 60 minutes was correctly identified. Conclusions A method was developed to predict prolonged RR intervals using two parameters and prior statistical sampling for each patient. This or similar methodology may help improve cardiac imaging in many longstanding persistent AF patients. PMID:23998759

Ethograms indicate stable well-being during prolonged training phases in rhesus monkeys used in neurophysiological research.

Awake, behaving rhesus monkeys are widely used in neurophysiological research. Neural signals are typically measured from monkeys trained with operant conditioning techniques to perform a variety of behavioral tasks in exchange for rewards. Over the past years, monkeys' psychological well-being during experimentation has become an increasingly important concern. We suggest objective criteria to explore whether training sessions during which the monkeys work under controlled water intake over many days might affect their behavior. With that aim, we analyzed a broad range of species-specific behaviors over several months ('ethogram') and used these ethograms as a proxy for the monkeys' well-being. Our results show that monkeys' behavior during training sessions is unaffected by the duration of training-free days in-between. Independently of the number of training-free days (two or nine days) with ad libitum food and water supply, the monkeys were equally active and alert in their home group cages during training phases. This indicates that the monkeys were well habituated to prolonged working schedules and that their well-being was stably ensured during the training sessions.

Women's experiences of becoming a mother after prolonged labour.

Nystedt, Astrid; Högberg, Ulf; Lundman, Berit

2008-08-01

This paper is a report of a study to explore women's experiences of becoming a mother after prolonged labour. The negativity associated with a complicated labour such as prolonged labour can lead to a struggle to become a healthy mother and could restrict the process of becoming a mother. Interviews were conducted in 2004 with 10 mothers who had been through a prolonged labour with assisted vaginal or caesarean delivery 1-3 months previously. Thematic content analysis was used. Three themes were formulated, describing women's experiences as fumbling in the dark, struggling for motherhood and achieving confidence in being a mother. The difficulties and suffering involved in becoming a mother after a prolonged labour were interpreted to be like 'fumbling in the dark'. Women experienced bodily fatigue, accompanied by feelings of illness and detachment from the child. Having the child when in this condition entailed a struggle to become a mother. In spite of these experiences and the desire to achieve confidence in being a mother, the reassurance of these women regarding their capacity for motherhood was crucial: it was central to their happiness as mothers, encouraged interaction and relationship with the child, and contributed to their adaptation to motherhood. Women experiencing prolonged labour may be comparable with the experience of and recovery from illness, which could contribute to difficulties transitioning to motherhood and limit a woman's ability to be emotionally available for the child.

Single prolonged stress impairs social and object novelty recognition in rats.

Posttraumatic stress disorder (PTSD) results from exposure to a traumatic event and manifests as re-experiencing, arousal, avoidance, and negative cognition/mood symptoms. Avoidant symptoms, as well as the newly defined negative cognitions/mood, are a serious complication leading to diminished interest in once important or positive activities, such as social interaction; however, the basis of these symptoms remains poorly understood. PTSD patients also exhibit impaired object and social recognition, which may underlie the avoidance and symptoms of negative cognition, such as social estrangement or diminished interest in activities. Previous studies have demonstrated that single prolonged stress (SPS), models PTSD phenotypes, including impairments in learning and memory. Therefore, it was hypothesized that SPS would impair social and object recognition memory. Male Sprague Dawley rats were exposed to SPS then tested in the social choice test (SCT) or novel object recognition test (NOR). These tests measure recognition of novelty over familiarity, a natural preference of rodents. Results show that SPS impaired preference for both social and object novelty. In addition, SPS impairment in social recognition may be caused by impaired behavioral flexibility, or an inability to shift behavior during the SCT. These results demonstrate that traumatic stress can impair social and object recognition memory, which may underlie certain avoidant symptoms or negative cognition in PTSD and be related to impaired behavioral flexibility.

Athanassoglou, Vassilis; Wallis, Anna; Galitzine, Svetlana

2015-11-01

Lower limb orthopedic operations are frequently performed under regional anesthesia, which allows avoidance of potential side effects and complications of general anesthesia and sedation. Often though, patients feel anxious about being awake during operations. To decrease intraoperative anxiety, we use multimedia equipment consisting of a tablet device, noise-canceling headphones, and a makeshift frame, where patients can listen to music, watch movies, or occupy themselves in numerous ways. These techniques have been extensively studies in minimally invasive, short, or minor procedures but not in prolonged orthoplastic operations. We report 2 cases where audiovisual distraction was successfully applied to 9.5-hour procedures, proved to be a very useful adjunct to epidural anesthesia + sedation, and made an important contribution to positive patients' outcomes and overall patients' experience with regional anesthesia for complex limb reconstructive surgery. In the era when not only patients' safety and clinical outcomes but also patients' positive experiences are of paramount importance, audiovisual distraction may provide a simple tool to help improve experience of appropriately informed patients undergoing suitable procedures under regional anesthesia. The anesthetic technique received a very positive appraisal by both patients and encouraged us to study further the impact of modern audiovisual technology on anxiolysis for major surgery under regional anesthesia. The duration of surgery per se is not a contraindication to the use of audiovisual distraction. The absolute proviso of successful application of this technique to major surgery is effective regional anesthesia and good teamwork between the clinicians and the patients.

Raftry, Sean M; Marshall, Paul W M

2012-06-01

The purpose of this study was to investigate the relationship between hamstring passive stiffness and extensibility in asymptomatic individuals with the reporting of low back pain during 2-h prolonged standing. Twenty healthy participants with no history of low back pain (mean±SD, age 22.6±2.7 years, height 1.74±0.09 m, weight 76.2±14.8 kg). Low back pain (VAS score; mm) was continuously monitored during 2-h prolonged standing. Hamstring extensibility, passive stiffness, and stretch tolerance were measured before and after prolonged standing using an instrumented straight leg raise (iSLR). Ten participants reported a clinically relevant increase (Δ VAS>10mm) in low back pain during prolonged standing. Hamstring extensiblity (leg°(max)), passive stiffness (Nm.°(-1)), and stretch tolerance (VAS; mm) were no different between pain developers and non-pain developers. No changes in hamstring measures were observed following 2-h prolonged standing. No relationship was observed in this study between measures of hamstring extensibility and the reporting of low back pain during prolonged standing. There is no evidence to recommend hamstring extensibility interventions (i.e. passive stretching) as a means of reducing pain reporting in occupations requiring prolonged standing.

Tout, K; de Haan, M; Campbell, E K; Gunnar, M R

1998-10-01

The relations between social behavior and daily patterns of a stress-sensitive hormone production were examined in preschool children (N = 75) attending center-based child care. Three behavioral dimensions, shy/anxious/internalizing, angry/aggressive/externalizing, and social competence, were assessed by teacher report and classroom observation, and their relations with 2 measures of cortisol activity, median (or typical) levels and reactivity (quartile range score between second and third quartile values) were explored. Cortisol-behavior relations differed by gender: significant associations were found for boys but not for girls. Specifically, for boys externalizing behavior was positively associated with cortisol reactivity, while internalizing behavior was negatively associated with median cortisol. Time of day of cortisol measurement affected the results. Surprisingly, median cortisol levels rose from morning to afternoon, a pattern opposite to that of the typical circadian rhythm of cortisol. This rise in cortisol over the day was positively correlated with internalizing behavior for boys. The methodological and theoretical implications of these findings for the study of the development of hormone-behavior relations are discussed.

Stress-related behavioral alterations accompanying cocaine toxicity: the effects of mixed opioid drugs.

Hayase, T; Yamamoto, Y; Yamamoto, K

2000-12-01

The present study evaluated the effects of mixed opioid drugs on the severity of cocaine (COCA) toxicity by examining stress-related behavioral alterations in mice. In order to ascertain the strength of the stress, the continuous observation of the behavioral symptoms in the cage and the forced swimming test (Porsolt test) were performed in the COCA (75 mg/kg, i.p.)-treated groups, with or without the mixed mu-kappa receptor-related opioid drugs, buprenorphine (BUP) and pentazocine (PEN). Using the high-sensitivity activity measuring instrument Supermex, both the spontaneous behaviors in the cage and the forced swimming behaviors in the water were assessed as activity counts. The behavioral alterations in the COCA-treated groups were compared with a group of mice given a 10 min immobilization stress (IM group). In the COCA-only group, a prolonged increase in the spontaneous behaviors accompanied by convulsive seizures was observed even in the surviving mice, unlike in the IM group. However, an acceleration of behavioral despair in the Porsolt test similar to that observed in the IM group was observed in the COCA group after the disappearance of the acute toxic symptoms (5 hours after the COCA treatment). Among the opioid-treated groups, the mortality rate was attenuated only in the COCA-BUP (0.25 mg/kg, i.p.) group. In the COCA-BUP group, a prolonged suppression of the morbid hyperactivity in the cage except for the convulsive seizures, and a normalization of the swimming behavior in the Porsolt test were observed in the survivors. On the other hand, in the COCA-PEN (5 mg/kg, i.p.) group, the swimming behavior in the Porsolt test was abnormally increased in addition to the prolonged morbid hyperactivity in the cage. Therefore, the COCA-induced stress-related behaviors were normalized in the group of mice treated with BUP, a group with a good prognosis.

This study evaluates the efficacy of integrating PTSD treatment into Dialectical Behavior Therapy (DBT) for women with borderline personality disorder, PTSD, and intentional self-injury. Participants were randomized to DBT (n=9) or DBT with the DBT Prolonged Exposure (DBT PE) protocol (n=17) and assessed at 4-month intervals during the treatment year and 3-months post-treatment. Treatment expectancies, satisfaction, and completion did not differ by condition. In DBT+DBT PE, the DBT PE protocol was feasible to implement for a majority of treatment completers. Compared to DBT, DBT+DBT PE led to larger and more stable improvements in PTSD and doubled the remission rate among treatment completers (80% vs. 40%). Patients who completed the DBT PE protocol were 2.4 times less likely to attempt suicide and 1.5 times less likely to self-injure than those in DBT. Among treatment completers, moderate to large effect sizes favored DBT+DBT PE for dissociation, trauma-related guilt cognitions, shame, anxiety, depression, and global functioning. DBT with the DBT PE protocol is feasible, acceptable, and safe to administer, and may lead to larger improvements in PTSD, intentional self-injury, and other outcomes than DBT alone. The findings require replication in a larger sample. Copyright © 2014 Elsevier Ltd. All rights reserved.

Newly recognized turbidity current structure can explain prolonged flushing of submarine canyons.

Seabed-hugging flows called turbidity currents are the volumetrically most important process transporting sediment across our planet and form its largest sediment accumulations. We seek to understand the internal structure and behavior of turbidity currents by reanalyzing the most detailed direct measurements yet of velocities and densities within oceanic turbidity currents, obtained from weeklong flows in the Congo Canyon. We provide a new model for turbidity current structure that can explain why these are far more prolonged than all previously monitored oceanic turbidity currents, which lasted for only hours or minutes at other locations. The observed Congo Canyon flows consist of a short-lived zone of fast and dense fluid at their front, which outruns the slower moving body of the flow. We propose that the sustained duration of these turbidity currents results from flow stretching and that this stretching is characteristic of mud-rich turbidity current systems. The lack of stretching in previously monitored flows is attributed to coarser sediment that settles out from the body more rapidly. These prolonged seafloor flows rival the discharge of the Congo River and carry ~2% of the terrestrial organic carbon buried globally in the oceans each year through a single submarine canyon. Thus, this new structure explains sustained flushing of globally important amounts of sediment, organic carbon, nutrients, and fresh water into the deep ocean.

"It's not an Obvious Issue, Is It?" Office-Based Employees' Perceptions of Prolonged Sitting at Work: A Qualitative Study.

Flint, Stuart William; Crank, Helen; Tew, Garry; Till, Simon

2017-12-01

Current UK workplace health promotion guidance recommends that employers minimize sedentary behaviors, but understanding the issues relating to prolonged workplace sitting has received little empirical attention. This study aimed to explore employees' perceptions of sitting time. Participants at a small to medium-sized UK company were invited to join one of five focus groups. A framework analysis approach was used. Self-reported mean estimate of occupational sitting time was 6.4 hours/day with a mean estimate of leisure time sitting 6.5 hours/nonwork days. The study highlighted employees' lack of appreciation of the health risks associated with sedentary behavior. This study has highlighted that in addition to personal determinants, the workplace environment and organizational culture have a key role in supporting employees' potential adoption of healthier sitting behavior in the workplace.

An urgent need exists to better understand the transition from short-term opioid use to unintended prolonged opioid use (UPOU). The purpose of this work is to propose a conceptual framework for understanding UPOU that posits the influence of 3 principal domains that include the characteristics of (1) individual patients, (2) the practice environment, and (3) opioid prescribers. Although no standardized method exists for developing a conceptual framework, the process often involves identifying corroborative evidence, leveraging expert opinion to identify factors for inclusion in the framework, and developing a graphic depiction of the relationships between the various factors and the clinical problem of interest. Key patient characteristics potentially associated with UPOU include (1) medical and mental health conditions; (2) pain etiology; (3) individual affective, behavioral, and neurophysiologic reactions to pain and opioids; and (4) sociodemographic factors. Also, UPOU could be influenced by structural and health care policy factors: (1) the practice environment, including the roles of prescribing clinicians, adoption of relevant practice guidelines, and clinician incentives or disincentives, and (2) the regulatory environment. Finally, characteristics inherent to clinicians that could influence prescribing practices include (1) training in pain management and opioid use; (2) personal attitudes, knowledge, and beliefs regarding the risks and benefits of opioids; and (3) professionalism. As the gatekeeper to opioid access, the behavior of prescribing clinicians directly mediates UPOU, with the 3 domains interacting to determine this behavior. This proposed conceptual framework could guide future research on the topic and allow plausible hypothesis-based interventions to reduce UPOU.

Tina D. Du Rocher Schudlich

2013-06-01

Full Text Available This study investigated associations between adult romantic attachment and couples’ conflict behaviors and the potential mediating role of intimacy. A community sample of 74 couples reported on their attachment security style on the Attachment Style Measure (ASM (Simpson, 1990 and on multiple dimensions of intimacy on the Personal Assessment of Intimacy in Relationships (PAIR (Schaefer & Olson, 1981. Couples’ conflict behaviors were assessed via behavioral observations and coded for positive and negative dimensions of conflict. Path analyses indicated numerous actor and partner effects in the links between attachment, intimacy, and conflict. For men, both avoidant and anxious attachment styles were predictive of their own and their partner’s intimacy. For women though, both secure and avoidant attachment styles were predictive of their own and their partner’s intimacy. For men, all domains of intimacy were predictive of their own or their partner’s conflict behaviors. For women, only emotional intimacy was predictive of conflict behaviors. All domains of men’s intimacy emerged as significant mediators of associations between attachment and couples’ conflict behaviors. For women, only emotional intimacy mediated these associations. Implications for the treatment of relationally-discordant couples are discussed.

2009-07-01

Full Text Available The purpose of this study was to assess the effectiveness of a behavioral parent therapy (BPT program in children with attention-deficit hyperactivity disorder (ADHD using multidimensional evaluations, the Child Behavior Checklist (CBCL and the Teacher Report Form (TRF. Between 2001 and 2005, the parents of 21 preschool children with ADHD were divided into six groups and participated in a series of 11 BPT sessions. Before and after BPT, the parents completed the CBCL, and the teachers completed the TRF. The behavioral and emotional problems of the children showed improvement after the BPT sessions, specifically for the following categories: internalizing problems, anxious/depressed syndromes, somatic complaints, externalizing problems, rule-breaking behaviors, aggressive behaviors, social problems, thought problems, and attention problems. In the DSM-oriented scale of the CBCL, affective problems, anxiety problems, somatic problems, ADHD problems, oppositional defiant disorder problems, and conduct disorder problems showed significant improvements. On the DSM scale of the TRF, Inattention syndrome improved significantly after the BPT sessions, while other syndromes showed non-significant changes. We conclude that the BPT program significantly improved the children's behavioral problems at home and inattention problems at school.

Social anxiety and cardiovascular responses to active coping conditions

Directory of Open Access Journals (Sweden)

MARGIT GRAMER

2006-03-01

Full Text Available This study assessed the influence of trait social anxiety on cardiovascular, emotional and behavioral responses to active performance situations representing social and cognitive demands. Thirty-six male and thirty-six female students categorized as either high or low in trait social anxiety performed a mental arithmetic task and two interpersonal tasks requiring persuasive behavior: Preparation and Performance of a Speech, Role-played Interpersonal Interactions. The cardiovascular effects of social anxiety varied over experimental stressors and appear to reflect differences in effort or task engagement rather than differential affective experiences. During Role-played Interactions high socially anxious subjects displayed lower increases in systolic blood pressure compared to low anxious participants. This effect was partially mediated by behavioral indicators of social competence and suggests a more inhibited coping approach of socially anxious participants. Findings for Mental Arithmetic were in the opposite direction, high socially anxious subjects displayed greater heart rate effects. In the absence of group differences in state anxiety this effect might result from stronger audience effects on effort or task motivation in socially anxious participants. These findings strengthen the view that active performance situations elicit cardiovascular effects that are largely attributable to differences in task engagement. The data also indicate the importance of considering situational factors in social anxiety research.

Loss aversion and 5HTT gene variants in adolescent anxiety

Directory of Open Access Journals (Sweden)

Monique Ernst

2014-04-01

Full Text Available Loss aversion, a well-documented behavioral phenomenon, characterizes decisions under risk in adult populations. As such, loss aversion may provide a reliable measure of risky behavior. Surprisingly, little is known about loss aversion in adolescents, a group who manifests risk-taking behavior, or in anxiety disorders, which are associated with risk-avoidance. Finally, loss aversion is expected to be modulated by genotype, particularly the serotonin transporter (SERT gene variant, based on its role in anxiety and impulsivity. This genetic modulation may also differ between anxious and healthy adolescents, given their distinct propensities for risk taking. The present work examines the modulation of loss aversion, an index of risk-taking, and reaction-time to decision, an index of impulsivity, by the serotonin-transporter-gene-linked polymorphisms (5HTTLPR in healthy and clinically anxious adolescents. Findings show that loss aversion (1 does manifest in adolescents, (2 does not differ between healthy and clinically anxious participants, and (3, when stratified by SERT genotype, identifies a subset of anxious adolescents who are high SERT-expressers, and show excessively low loss-aversion and high impulsivity. This last finding may serve as preliminary evidence for 5HTTLPR as a risk factor for the development of comorbid disorders associated with risk-taking and impulsivity in clinically anxious adolescents.

Background Prolonged labour very often causes suffering from difficulties that may have lifelong implications. This study aimed to explore the prevalence and treatment of prolonged labour and to compare birth outcome and women’s experiences of prolonged and normal labour. Method Women with spontaneous onset of labour, living in a Swedish county, were recruited two months after birth, to a cross-sectional study. Women (n = 829) completed a questionnaire that investigated socio-demographic and obstetric background, birth outcome and women’s feelings and experiences of birth. The prevalence of prolonged labour, as defined by a documented ICD-code and inspection of partogram was calculated. Four groups were identified; women with prolonged labour as identified by documented ICD-codes or by partogram inspection but no ICD-code; women with normal labour augmented with oxytocin or not. Results Every fifth woman experienced a prolonged labour. The prevalence with the documented ICD-code was (13%) and without ICD-code but positive partogram was (8%). Seven percent of women with prolonged labour were not treated with oxytocin. Approximately one in three women (28%) received oxytocin augmentation despite having no evidence of prolonged labour. The length of labour differed between the four groups of women, from 7 to 23 hours. Women with a prolonged labour had a negative birth experience more often (13%) than did women who had a normal labour (3%) (P women with prolonged labour were emergency Caesarean section (OR 9.0, 95% CI 1.2-3.0) and to strongly agree with the following statement ‘My birth experience made me decide not to have any more children’ (OR 41.3, 95% CI 4.9-349.6). The factors that contributed most strongly to a negative birth experience in women with normal labour were less agreement with the statement ‘It was exiting to give birth’ (OR 0.13, 95% CI 0.34-0.5). Conclusions There is need for increased clinical skill in identification and classification

Elephant seals naturally experience prolonged periods of absolute food and water deprivation (fasting). In humans, rats and mice, prolonged food deprivation activates the renin-angiotensin system (RAS) and increases oxidative damage. In elephant seals, prolonged fasting activates RAS without increasing oxidative damage likely due to an increase in antioxidant defenses. The mechanism leading to the upregulation of antioxidant defenses during prolonged fasting remains elusive. Therefore, we investigated whether prolonged fasting activates the redox-sensitive transcription factor Nrf2, which controls the expression of antioxidant genes, and if such activation is potentially mediated by systemic increases in RAS. Blood and skeletal muscle samples were collected from seals fasting for 1, 3, 5 and 7 weeks. Nrf2 activity and nuclear content increased by 76% and 167% at week 7. Plasma angiotensin II (Ang II) and transforming growth factor β (TGF-β) were 5000% and 250% higher at week 7 than at week 1. Phosphorylation of Smad2, an effector of Ang II and TGF signaling, increased by 120% at week 7 and by 84% in response to intravenously infused Ang II. NADPH oxidase 4 (Nox4) mRNA expression, which is controlled by smad proteins, increased 430% at week 7, while Nox4 protein expression, which can activate Nrf2, was 170% higher at week 7 than at week 1. These results demonstrate that prolonged fasting activates Nrf2 in elephant seals and that RAS stimulation can potentially result in increased Nox4 through Smad phosphorylation. The results also suggest that Nox4 is essential to sustain the hormetic adaptive response to oxidative stress in fasting seals.

Case series (longitudinal). Only few reports concerning the efficacy of commonly used strategies for preventing upper limb occupational disorders associated with prolonged typing exist. We aimed to investigate whether the duration of typing and the use of 2 strategies (hand rest and wrist support) changes muscle physiological response and therefore the electromyography records. We enrolled 25 volunteers, who were unfamiliar with the task and did not have musculoskeletal disorders. The subjects underwent 3 prolonged typing protocols to investigate the efficacy of the 2 adopted strategies in reducing the trapezius, biceps brachii, and extensor digitorum communis fatigue. Typing for 1 hour induced muscular fatigue (60%-67% of the subjects). The extensor digitorum communis muscle exhibited the highest percentage of fatigue (72%-84%) after 1 and 4 hours of typing (1 hour, P = .04; 4 hours, P = .02). Fatigue levels in this muscle were significantly reduced (24%) with the use of pause typing (4 hours, P = .045), whereas biceps brachii muscle fatigue was reduced (32%) only with the use of wrist supports (P = .02, after 4 hours). Trapezius muscle fatigue was unaffected by the tested occupational strategies (1 hour, P = .62; 4 hours, P = .85). Despite presenting an overall tendency for fatigue detected during the application of the protocols, the assessed muscles exhibited different behavior patterns, depending on both the preventive strategy applied and the muscle mechanical role during the task. Hand rest and wrist support can successfully reduce muscle fatigue in specific upper limb muscles during prolonged typing, leading to a muscle-selective reduction in the occurrence of fatigue and thus provide direct evidence that they may prevent work-related musculoskeletal disorders.

Full Text Available Currently available local anesthetics have analgesic durations in humans generally less than 12 hours. Prolonged-duration local anesthetics will be useful for postoperative analgesia. Previous studies showed that in rats, combinations of tetrodotoxin (TTX with bupivacaine had supra-additive effects on sciatic block durations. In those studies, epinephrine combined with TTX prolonged blocks more than 10-fold, while reducing systemic toxicity. TTX, formulated as Tectin, is in phase III clinical trials as an injectable systemic analgesic for chronic cancer pain. Here, we examine dose-duration relationships and sciatic nerve histology following local nerve blocks with combinations of Tectin with bupivacaine 0.25% (2.5 mg/mL solutions, with or without epinephrine 5 µg/mL (1:200,000 in rats. Percutaneous sciatic blockade was performed in Sprague-Dawley rats, and intensity and duration of sensory blockade was tested blindly with different Tectin-bupivacaine-epinephrine combinations. Between-group comparisons were analyzed using ANOVA and post-hoc Sidak tests. Nerves were examined blindly for signs of injury. Blocks containing bupivacaine 0.25% with Tectin 10 µM and epinephrine 5 µg/mL were prolonged by roughly 3-fold compared to blocks with bupivacaine 0.25% plain (P < 0.001 or bupivacaine 0.25% with epinephrine 5 µg/mL (P < 0.001. Nerve histology was benign for all groups. Combinations of Tectin in bupivacaine 0.25% with epinephrine 5 µg/mL appear promising for prolonged duration of local anesthesia.

The objective of this study was to characterize the different causes of prolonged sternal pain following thoracic trauma with involvement of the sternum and to define criteria for sternal nonunion diagnosis using MRI. Five patients with abnormalities of the sternum were evaluated for prolonged sternal pain following thoracic trauma using MRI. MR images were evaluated by two radiologists in consensus. The patients were selected from the radiology database, which included 8 patients with post-traumatic prolonged sternal pain. Two patients (n = 2) revealed a sternal nonunion after sternal fracture. One patient had a sternal fracture with delayed union and minor displacement of the sternal halves. Abnormal signal intensity alterations adjacent to and within the manubrio-sternal joint were evident in 2 patients and considered due to trauma-related changes in the manubrio-sternal joint. The 3 patients who were not included in the study had no abnormalities of the sternum: 1 of them proved to have a well-healed sternal fracture and nonunion of a rib fracture, 1 had subtle Tietze's syndrome, and 1 patient revealed no pathological findings on imaging. Various factors may be responsible for prolonged sternal pain following thoracic trauma, and these can be viewed with MRI. In cases of sternal nonunion there was common fluid-like signal in the fracture interspace between the bony edges, and the bone marrow adjacent to the nonunion showed altered signal intensity. MRI identified sternal nonunion and other trauma-related abnormalities of the sternum following chest trauma. (orig.)

Observations performed in a subset of subjects treated with finasteride (an inhibitor of the enzyme 5α-reductase) for male pattern hair loss seem to indicate that sexual dysfunction as well as anxious/depressive symptomatology may occur at the end of the treatment and continue after discontinuation. A possible hypothesis to explain depression symptoms after finasteride treatment might be impairment in the levels of neuroactive steroids. Therefore, neuroactive steroid levels were evaluated in paired plasma and cerebrospinal fluid samples obtained from male patients who received finasteride for the treatment of androgenic alopecia and who, after drug discontinuation, still show long-term sexual side effects as well as anxious/depressive symptomatology. The levels of neuroactive steroids were evaluated by liquid chromatography-tandem mass spectrometry in three postfinasteride patients and compared to those of five healthy controls. Neuroactive steroid levels in plasma and cerebrospinal fluid of postfinasteride patients and healthy controls. At the examination, the three postfinasteride patients reported muscular stiffness, cramps, tremors, and chronic fatigue in the absence of clinical evidence of any muscular disorder or strength reduction. Severity and frequency of the anxious/depressive symptoms were quite variable; overall, all the subjects had a fairly complex and constant neuropsychiatric pattern. Assessment of neuroactive steroid levels in patients showed some interindividual differences. However, the most important finding was the comparison of their neuroactive steroid levels with those of healthy controls. Indeed, decreased levels of tetrahydroprogesterone, isopregnanolone and dihydrotestosterone and increased levels of testosterone and 17β-estradiol were reported in cerebrospinal fluid of postfinasteride patients. Moreover, decreased levels of dihydroprogesterone and increased levels of 5α-androstane-3α,17β-diol and 17β-estradiol were observed in

This study examined the nature and correlates of hoarding among youth with autism spectrum disorders (ASD). Forty children with ASD and a comorbid anxiety disorder were administered a battery of clinician-administered measures assessing presence of psychiatric disorders and anxiety severity. Parents completed questionnaires related to child hoarding behaviors, social responsiveness, internalizing and externalizing behaviors, and functional impairment. We examined the impact of hoarding behaviors on treatment response in a subsample of twenty-six youth who completed a course of personalized cognitive-behavioral therapy targeting anxiety symptoms. Hoarding symptoms were common and occurred in a clinically significant manner in approximately 25 % of cases. Overall hoarding severity was associated with increased internalizing and anxiety/depressive symptoms, externalizing behavior, and attention problems. Discarding items was associated with internalizing and anxious/depressive symptoms, but acquisition was not. Hoarding decreased following cognitive-behavioral therapy but did not differ between treatment responders and non-responders. These data are among the first to examine hoarding among youth with ASD; implications of study findings and future directions are highlighted.

Kerns, Kathryn A; Siener, Shannon; Brumariu, Laura E

2011-05-01

The goal of the study was to examine several factors that may explain the development of anxiety symptoms in middle childhood. Using data from the NICHD Study of Early Child Care (n = 1,364 families), we examined mother-child relationships, other aspects of family context, and child characteristics as predictors of anxiety in preadolescence. Latent growth curve analyses revealed that children who were more anxious at the beginning of middle childhood had been more behaviorally inhibited as preschoolers, and in middle childhood lived in families who experienced more negative life events and had mothers who were more anxious. Children who became more anxious across middle childhood were less behaviorally inhibited as preschoolers and in middle childhood perceived less security in their attachments to their mothers, experienced more negative life events, and had mothers who were more anxious. The findings illustrate the need to include a broad set of risk factors in etiological models of anxiety. In addition, the evidence for cumulative effects suggests several possible points of intervention with anxious children and their parents.

To evaluate the effect of prenatal exposure to selective serotonin reuptake inhibitors (SSRIs) on children's behavioral, emotional, and social development by age 5 years, and over time since age 1.5 years. The prospective Norwegian Mother and Child Cohort Study was linked to the Medical Birth Registry of Norway. We included women who reported depressive/anxiety disorders before and/or during pregnancy. Children born to women who used SSRIs in early (weeks 0-16), mid- (weeks 17-28), or late (> week 29) pregnancy were compared to those who were unexposed. Children's internalizing and externalizing behaviors (Child Behavior Checklist) and temperament traits (Emotionality, Activity and Shyness Temperament Questionnaire) were measured at 1.5, 3, and 5 years. Mean scores were calculated and standardized. General linear marginal structural models were fitted to account for time-varying exposure and confounders, and censoring; 3-level growth-curve models were used. A total of 8,359 mother-child dyads were included, and 4,128 children had complete outcome data at age 5 years. Children exposed to SSRIs in late pregnancy had an increased risk of anxious/depressed behaviors by age 5 years compared with unexposed children (adjusted β = 0.50, 95% CI = 0.04, 0.96). Such risk was not evident for earlier timings of exposure. There was no evidence for a substantial prenatal SSRI effect on externalizing, social, and emotional problems. These findings suggest no substantial increased risk for externalizing, emotional, or social problems in preschool-aged children following prenatal SSRI exposure. Although the role of chance and potential unmeasured confounding cannot be ruled out, late-pregnancy SSRI exposure was associated with greater anxious/depressed behaviors in the offspring.

Taira, Carlos A; Opezzo, Javier A W; Mayer, Marcos A; Höcht, Christian

2010-01-01

Acquired QT syndrome is mainly caused by the administration of drugs that prolong ventricular repolarization. On the other hand, the risk of drug-induced torsades de pointes is increased by numerous predisposing factors, such as genetic predisposition, female sex, hypokalemia and cardiac dysfunction. This adverse reaction is induced by different chemical compounds used for the treatment of a variety of pathologies, including arrhythmias. As it is known, antiarrhythmic agents and other cardiovascular drugs can prolong the QT interval, causing this adverse reaction. Of the 20 most commonly reported drugs, 10 were cardiovascular agents and these appeared in 348 of the reports (46%). Class Ia antiarrhythmic agents have frequently been linked to inducing arrhythmia, including torsades de pointes. Sotalol and amiodarone, class III antiarrhythmics, are known to prolong the QT interval by blocking I(Kr). Due to the severity of events caused by the therapeutic use of these drugs, in this work of revision the cardiovascular drugs that present this property and the factors and evidence will be mentioned.

Primary headache is a frequent and disabling disorder, common among children and adolescents, and it is a painful syndrome often accompanied by functional impairment and associated with emotional and behavior problems. The aim of this study was to investigate parenting stress and emotional/behavioral problems in adolescents affected by primary headache compared with healthy adolescents. The study population consisted of 35 adolescents and a control group of 23 healthy subjects. The assessment included the administration of clinical standardized scales such as Parent Stress Index-Short Form, Pediatric Migraine Disability Assessment Score Questionnaire, and Child Behavior Checklist (CBCL). Headache group and control group did not differ in terms of parenting stress ( p  = 0.29). On the contrary, headache group showed more internalizing problems ( p  = 0.023), affective problems ( p  = 0.01), anxious ( p  = 0.001), and somatic complaints ( p  headache group. The findings emphasize the need for expanded intervention in the clinical treatment of pediatric headache, a treatment that may also include the family members. Further research is needed.

Recent studies have shown that potentially fatal hyponatremia can develop during prolonged exercise. To determine the incidence of hyponatremia in athletes competing in ultradistance events, we measured serum sodium levels in 315 of 626 (50%) runners who were treated for collapse after two 90 km ultramarathon footraces (total starters 20,335; total finishers 18,031) and in 101 of 147 (69%) finishers in a 186 km ultratriathlon. In both races the athletes drank fluids with low sodium chloride content (less than 6.8 mmol.l-1). Hyponatremia (serum sodium level less than 130 mmol.l-1) was identified in 27 of 315 (9%) collapsed runners in the 90 km races and in none of the triathletes. In response to diuretic therapy, the runner with the most severe hyponatremia (serum sodium level = 112 mmol.l-1) excreted in excess of 7.5 l dilute urine during the first 17 h of hospitalization. These data suggest that, although symptomatic hyponatremia occurs in less than 0.3% of competitors during prolonged exercise even when they ingest little sodium chloride, it is found in a significant proportion (9%) of collapsed runners. A regulated contraction of the extracellular fluid volume would explain why the majority of athletes maintain normal serum sodium levels even though they develop a significant sodium chloride deficit during prolonged exercise. Alternatively, sodium chloride losses during prolonged exercise may be substantially less than are currently believed. Physicians treating collapsed ultradistance athletes need to be aware that as many as 10% or more of such patients may be hyponatremic.

Prolonged sitting is detrimentally associated with health outcomes. However, the prevalence and characteristics of those who sit in cars for long periods are not well understood. This study examined the population prevalence, socio-demographic variations, and trends for prolonged sitting in cars among adults. Using the Sydney Greater Metropolitan Area Household Travel Survey, the prevalence of prolonged sitting time in cars (≥2 h/day) was calculated for four 3-year periods (1997-99, 2000-02, 2003-05, and 2006-08) for each population subgroup. Trends were calculated as the mean change in prevalence between adjacent survey periods. Cars were used for 66% of the total trips recorded (n=336,505). The prevalence of prolonged sitting time in cars was 16-18% in men, and 10-12% in women. Relatively higher prevalence rates were found among middle-age groups (men: 20-22%, women: 12-15%), full-time workers (men: 21-24%, women: 14-15%), those with higher income (men: 21-25%, women: 14-16%), couples with children (men: 20-21%, women: 12-14%), and those living in outer suburbs (men: 20-23%, women: 12-13%). Trends were stable in men, but increasing in women. Several subgroups (older age; living in regional suburbs) also showed increasing trends. These findings provide evidence to inform integrated approaches to measurement and policy development on prolonged car use among the public health, urban planning, and transport sectors.

In the current study, 55 participants with a diagnosis of generalized social anxiety disorder (SAD), 23 participants with a diagnosis of an anxiety disorder other than SAD with no comorbid SAD, and 50 healthy controls completed a speech task as well as self-reported measures of safety behavior use. Speeches were videotaped and coded for global and specific indicators of performance by two raters who were blind to participants' diagnostic status. Results suggested that the objective performance of people with SAD was poorer than that of both control groups, who did not differ from each other. Moreover, self-reported use of safety behaviors during the speech strongly mediated the relationship between diagnostic group and observers' performance ratings. These results are consistent with contemporary cognitive-behavioral and interpersonal models of SAD and suggest that socially anxious individuals' performance skills may be undermined by the use of safety behaviors. These data provide further support for recommendations from previous studies that the elimination of safety behaviors ought to be a priority in cognitive behavioral therapy for SAD. Copyright © 2014.

Management of children with prolonged diarrhea [version 1; referees: 3 approved

Directory of Open Access Journals (Sweden)

2016-02-01

Full Text Available Prolonged diarrhea is usually defined as acute-onset diarrhea lasting 7 days or more, but less than 14 days. Its trend has been declining in recent years because of improvement in the management of acute diarrhea, which represents the ideal strategy to prevent prolonged diarrhea. The pathogenesis of prolonged diarrhea is multifactorial and essentially based on persistent mucosal damage due to specific infections or sequential infections with different pathogens, host-related factors including micronutrient and/or vitamin deficiency, undernutrition and immunodeficiency, high mucosal permeability due to previous infectious processes and nutrient deficiency with consequential malabsorption, and microbiota disruption. Infections seem to play a major role in causing prolonged diarrhea in both developing and developed areas. However, single etiologic pathogens have not been identified, and the pattern of agents varies according to settings, host risk factors, and previous use of antibiotics and other drugs. The management of prolonged diarrhea is complex. Because of the wide etiologic spectrum, diagnostic algorithms should take into consideration the age of the patient, clinical and epidemiological factors, and the nutritional status and should always include a search for enteric pathogens. Often, expensive laboratory evaluations are of little benefit in guiding therapy, and an empirical approach may be effective in the majority of cases. The presence or absence of weight loss is crucial for driving the initial management of prolonged diarrhea. If there is no weight loss, generally there is no need for further evaluation. If weight loss is present, empiric anti-infectious therapy or elimination diet may be considered once specific etiologies have been excluded.

Does Neighborhood Social Capital Buffer the Effects of Maternal Depression on Adolescent Behavior Problems?

Neighborhood characteristics have been shown to impact child well-being. However, it remains unclear how these factors combine with family characteristics to influence child development. The current study helps develop that understanding by investigating how neighborhoods directly impact child and adolescent behavior problems as well as moderate the influence of family characteristics on behavior. Using multilevel linear models, we examined the relationship among neighborhood conditions (poverty and social capital) and maternal depression on child and adolescent behavior problems. The sample included 741 children, age 5–11, and 564 adolescents, age 12–17. Outcomes were internalizing (e.g. anxious/depressed) and externalizing (e.g. aggressive/hyperactive) behavior problems. Neighborhood poverty and maternal depression were both positively associated with behavior problems for children and adolescents. However, while neighborhood social capital was not directly associated with behavior problems, the interaction of social capital and maternal depression was significantly related to behavior problems for adolescents. This interaction showed that living in neighborhoods with higher levels of social capital attenuated the relationship between maternal depression and adolescent behavior problems and confirmed the expectation that raising healthy well-adjusted children depends not only on the family, but also the context in which the family lives.

Full Text Available Clustering in wireless sensor networks is one of the crucial methods for increasing of network lifetime. The network characteristics of existing classical clustering protocols for wireless sensor network are homogeneous. Clustering protocols fail to maintain the stability of the system, especially when nodes are heterogeneous. We have seen that the behavior of Heterogeneous-Hierarchical Energy Aware Routing Protocol (H-HEARP becomes very unstable once the first node dies, especially in the presence of node heterogeneity. In this paper we assume a new clustering protocol whose network characteristics is heterogeneous for prolonging of network lifetime. The computer simulation results demonstrate that the proposed clustering algorithm outperforms than other clustering algorithms in terms of the time interval before the death of the first node (we refer to as stability period. The simulation results also show the high performance of the proposed clustering algorithm for higher values of extra energy brought by more powerful nodes.

Functional urinary incontinence and encopresis are common comorbid disorders in childhood. We analyze the specific somatic and behavioral symptoms associated with functional enuresis/urinary incontinence and encopresis when they occur together. A total of 167 consecutive children 5 to 10 year olds, with day and/or night wetting were examined prospectively with ultrasound, uroflowmetry, electroencephalography, the Child Behavior Checklist, Culture Fair Intelligence Test and ICD-10 child psychiatric diagnoses. The main findings for the comorbid group (20 patients) with wetting and soiling were a significantly higher rate of daytime incontinence and micturition problems, thickened bladder walls and pathological electroencephalography. There were higher, although not significant, rates of previous urinary tract infections, antibiotic prophylaxis, residual volume and abnormal uroflow curves in this group. Behaviorally, hyperkinetic syndromes, and emotional and conduct disorders (according to ICD-10) were more common. Of the 20 patients 65% had a Child Behavior Checklist total score (greater than 90th percentile) in the clinical range. The externalizing, internalizing, delinquent and anxious/depressed problem scales were also significantly higher. This risk group requires detailed assessment and specific treatment. In addition to the symptomatic treatment of the wetting and soiling, many of these children are in need of specific behavioral, psychotherapeutic and pharmacological treatment.

Loss aversion, a well-documented behavioral phenomenon, characterizes decisions under risk in adult populations. As such, loss aversion may provide a reliable measure of risky behavior. Surprisingly, little is known about loss aversion in adolescents, a group who manifests risk-taking behavior, or in anxiety disorders, which are associated with risk-avoidance. Finally, loss aversion is expected to be modulated by genotype, particularly the serotonin transporter (SERT) gene variant, based on its role in anxiety and impulsivity. This genetic modulation may also differ between anxious and healthy adolescents, given their distinct propensities for risk taking. The present work examines the modulation of loss aversion, an index of risk-taking, and reaction-time to decision, an index of impulsivity, by the serotonin-transporter-gene-linked polymorphisms (5HTTLPR) in healthy and clinically anxious adolescents. Findings show that loss aversion (1) does manifest in adolescents, (2) does not differ between healthy and clinically anxious participants, and (3), when stratified by SERT genotype, identifies a subset of anxious adolescents who are high SERT-expressers, and show excessively low loss-aversion and high impulsivity. This last finding may serve as preliminary evidence for 5HTTLPR as a risk factor for the development of comorbid disorders associated with risk-taking and impulsivity in clinically anxious adolescents.

Consistency of definitional criteria for terminology applied to describe subject cohorts receiving mechanical ventilation within ICU and post-acute care settings is important for understanding prevalence, risk stratification, effectiveness of interventions, and projections for resource allocation. Our objective was to quantify the application and definition of terms for prolonged mechanical ventilation. We conducted a scoping review of studies (all designs except single-case study) reporting a study population (adult and pediatric) using the term prolonged mechanical ventilation or a synonym. We screened 5,331 references, reviewed 539 full-text references, and excluded 120. Of the 419 studies (representing 38 countries) meeting inclusion criteria, 297 (71%) reported data on a heterogeneous subject cohort, and 66 (16%) included surgical subjects only (46 of those 66, 70% cardiac surgery). Other studies described COPD (16, 4%), trauma (22, 5%), neuromuscular (17, 4%), and sepsis (1, 0.2%) cohorts. A total of 741 terms were used to refer to the 419 study cohorts. The most common terms were: prolonged mechanical ventilation (253, 60%), admission to specialized unit (107, 26%), and long-term mechanical ventilation (79, 19%). Some authors (282, 67%) defined their cohorts based on duration of mechanical ventilation, with 154 studies (55%) using this as the sole criterion. We identified 37 different durations of ventilation ranging from 5 h to 1 y, with > 21 d being the most common (28 of 282, 7%). For studies describing a surgical cohort, minimum ventilation duration required for inclusion was ≥ 24 h for 20 of 66 studies (30%). More than half of all studies (237, 57%) did not provide a reason/rationale for definitional criteria used, with only 28 studies (7%) referring to a consensus definition. We conclude that substantial variation exists in the terminology and definitional criteria for cohorts of subjects receiving prolonged mechanical ventilation. Standardization of

To identify predictors influencing outcomes, we retrospectively examined the characteristics of inpatients with delirium who required psychiatric medication during hospitalization.Methods: We extracted all new inpatients (n=523 consulted for psychiatric symptoms at Fukushima Medical University Hospital between October 2011 and September 2013. We selected 203 inpatients with delirium diagnosed by psychiatrists. We analyzed data from 177 inpatients with delirium who received psychiatric medication. We defined an “early improvement group” in which delirium resolved in ≤3 days after starting psychiatric medication, and a “prolonged group” with delirium lasting for >3 days. Among the 83 inpatients with renal dysfunction (estimated glomerular filtration rate <60 mL/min/1.73 m2, we defined an “early improvement group with renal dysfunction” in which delirium resolved in ≤3 days after starting psychiatric medication and a “prolonged group with renal dysfunction” with delirium lasting for >3 days. We then examined differences between groups for different categorical variables.Results: Dose of antipsychotic medication at end point was significantly lower in the prolonged group with renal dysfunction than in the early improvement group with renal dysfunction.Conclusion: The results suggest that maintaining a sufficient dose of antipsychotics from an early stage may prevent prolongation of delirium even in inpatients with renal dysfunction.

Prolonged plasma creation in heterogeneous liners, in which the liner substance is separated into two phase states (a hot plasma and a cold skeleton), is investigated both experimentally and theoretically. This situation is typical of multiwire, foam, and even gas liners in high-current high-voltage facilities. The main mechanisms governing the rate at which the plasma is created are investigated, and the simplest estimates of the creation rate are presented. It is found that, during prolonged plasma creation, the electric current flows through the entire cross section of the produced plasma shell, whose thickness is comparable with the liner radius; in other words, a current skin layer does not form. During compression, such a shell is fairly stable because of its relatively high resilience. It is shown that, under certain conditions, even a thick plasma shell can be highly compressed toward the discharge axis. A simplified numerical simulation of the compression of a plasma shell in a liner with prolonged plasma creation is employed in order to determine the conditions for achieving regimes of fairly compact and relatively stable radial compression of the shell

Ciguatera results when ciguatoxin-contaminated coral reef fish from tropical or subtropical waters are consumed. The clinical features that present in affected persons are mainly gastrointestinal, neurological, general, and much less commonly, cardiovascular. We report the case of a 50-year-old man who developed the characteristic combination of acute gastrointestinal and neurological symptoms after the consumption of an unidentified coral reef fish head. In addition to those symptoms, he developed dizziness, severe bradycardia (46 bpm) and prolonged hypotension, which required the administration of intravenous atropine and over three days of intravenous fluid replacement with dopamine infusion. Patients with ciguatera can develop severe bradycardia and prolonged hypotension. Physicians should recognise the possible cardiovascular complications of ciguatera and promptly initiate treatment with intravenous atropine, intravenous fluid replacement and inotropic therapy if such complications are observed.

Up to one-third of children with concussion have prolonged symptoms lasting beyond 4 weeks. Vision and vestibular dysfunction is common after concussion. It is unknown whether such dysfunction predicts prolonged recovery. We sought to determine which vision or vestibular problems predict prolonged recovery in children. A retrospective cohort of pediatric patients with concussion. A subspecialty pediatric concussion program. Four hundred thirty-two patient records were abstracted. Presence of vision or vestibular dysfunction upon presentation to the subspecialty concussion program. The main outcome of interest was time to clinical recovery, defined by discharge from clinical follow-up, including resolution of acute symptoms, resumption of normal physical and cognitive activity, and normalization of physical examination findings to functional levels. Study subjects were 5 to 18 years (median = 14). A total of 378 of 432 subjects (88%) presented with vision or vestibular problems. A history of motion sickness was associated with vestibular dysfunction. Younger age, public insurance, and presence of headache were associated with later presentation for subspecialty concussion care. Vision and vestibular problems were associated within distinct clusters. Provocable symptoms with vestibulo-ocular reflex (VOR) and smooth pursuits and abnormal balance and accommodative amplitude (AA) predicted prolonged recovery time. Vision and vestibular problems predict prolonged concussion recovery in children. A history of motion sickness may be an important premorbid factor. Public insurance status may represent problems with disparities in access to concussion care. Vision assessments in concussion must include smooth pursuits, saccades, near point of convergence (NPC), and accommodative amplitude (AA). A comprehensive, multidomain assessment is essential to predict prolonged recovery time and enable active intervention with specific school accommodations and targeted rehabilitation.

We sought to establish if smokers on anti-tuberculosis treatment are more likely to have a prolonged period of infectivity, compared to non-smoking tuberculosis patients, in a low tuberculosis prevalence country. We conducted a cross-sectional, retrospective study in Ireland that recruited 53 microbiologically confirmed cases of pulmonary tuberculosis (PTB). The age-sex adjusted odds ratios (AOR) suggest that the infectivity status of PTB on treatment was four times more likely to be prolonged beyond 6-8 weeks, if the cases had a smoking history (AOR: 4.42; 95% CI: 1.23; 15.9). Smoking was associated with delayed sputum smear conversion in PTB patients on treatment.

Persons living with HIV (PLHIV) are a health disparity subgroup of the overall population for mental and physical health problems. HIV-related stigma has been shown to increase anxiety symptoms and HIV symptoms among PLHIV. However, little is known about factors that may impact the relations between HIV-related stigma and anxiety symptoms and HIV symptoms among PLHIV. To address this gap in the literature, the current study examined anxiety sensitivity (i.e., the extent to which individuals believe anxiety and anxiety-related sensations) in the relation between HIV-related stigma, social anxiety, anxious arousal, and HIV symptoms among a sample of 87 PLHIV (60.9% cis gender male, 52.9% Black, non-Hispanic). Results indicated that anxiety sensitivity mediated the relations between HIV-related stigma and the dependent variables, with effect sizes indicating moderate to large effects of anxiety sensitivity on these relations. Findings suggest that anxiety sensitivity be a mechanistic factor in the relations between HIV-related stigma and social anxiety, anxious arousal, and HIV symptoms, and therefore, be important element in efforts to reduce mental/physical health disparity among this population.

This study investigates if adults with adductor spasmodic dysphonia (ADSD) report to experience anxiety and voice problems in particular situations, indicate the presence of negative speech-associated attitude, and/or the use of coping behaviors, by means of the Behavior Assessment Battery (BAB) modified for voice. Thirty-two participants with ADSD and 32 adults without a voice disorder participated in this study. Each person completed four different BAB-Voice subtests. These standardized self-report tests are adaptations of the original BAB for people who stutter and explore an individual's speech-related belief, negative emotional reaction to and speech problems in particular speech situations, and the use of concomitant behaviors. Individuals with spasmodic dysphonia (SD) scored statistically significantly higher compared to typical speakers on all BAB subtests, indicating that individuals with SD report being significantly more anxious and experiencing significantly more voice problems in particular speech circumstances. They also reported a significant amount of negative speech-associated attitude and the use of a significant number of coping behaviors. Internal reliability was good for three of the four BAB subtests. The BAB is capable of reflecting the dimensions that surround the disorder of SD. The self-report measures have the potential to augment the observations made by the clinician and may lead to a more diverse and all-encompassing therapy for the person suffering from SD. Future research with a revised version of the BAB-Voice will continue to explore the validity, reliability, and replicability of the initial data. Published by Elsevier Inc.

The economic impact of disasters is well known; however, the link between financial loss and behavioral health problems is unknown. Participants included 198 adults of ages 21 to 82, living within 10 miles of the Gulf Coast during the Deepwater Horizon Oil Spill and were involved in the fishing, harvesting, seafood processing, or service/tourism industries. The functional impact of financial resource loss at 2.5 years post spill was measured using the 26-item Financial Life Events Checklist (FLEC). Individuals responded to financial distress by reducing social events and utility bills and changing food-shopping habits. The FLEC significantly predicted higher drug use (Drug Abuse Screening Test), alcohol use (Alcohol Use Disorders Identification Test), mood problems (Profile of Mood States), and depressive symptoms (Beck Depression Inventory II) (p values ≤ 0.05) 4.5 years after the spill. This preliminary study supports the notion that the functional impact of financial loss has a long-term impact on behavioral health after an oil spill.

Diet-consumer nitrogen isotope fractionation for prolonged fasting arthropods.

Mizota, Chitoshi; Yamanaka, Toshiro

2011-12-01

Nitrogen acquisition for cellular metabolism during diapause is a primary concern for herbivorous arthropods. Analyses of naturally occurring stable isotopes of nitrogen help elucidate the mechanism. Relevant articles have cited (58 times up to mid-June 2011) anomalously elevated δ(15)N (per mil deviation of (15)N/(14)N, relative to atmospheric nitrogen=0 ‰) values (diet-consumer nitrogen isotope fractionation; up to 12 ‰) for a prolonged fasting raspberry beetle (Byturus tomentosus Degeer (Coleoptera: Byturidae)), which feeds on red raspberries (Rubus idaeus: δ(15)N= ~ +2 ‰). Biologists have hypothesised that extensive recycling of amino acid nitrogen is responsible for the prolonged fasting. Since this hypothesis was proposed in 1995, scientists have integrated biochemical and molecular knowledge to support the mechanism of prolonged diapausing of animals. To test the validity of the recycling hypothesis, we analysed tissue nitrogen isotope ratios for four Japanese arthropods: the shield bug Parastrachia japonensis Scott (Hemiptera: Cydnidae), the burrower bug Canthophorus niveimarginatus Scott (Hemiptera: Cydnidae), leaf beetle Gastrophysa atrocyanea Motschulsky (Coleoptera: Chrysomelidae) and the Japanese oak silkworm Antheraea yamamai (Lepidoptera: Saturniidae), all of which fast for more than 6 months as part of their life-history strategy. Resulting diet-consumer nitrogen isotope discrimination during fasting ranged from 0 to 7‰, as in many commonly known terrestrial arthropods. We conclude that prolonged fasting of arthropods does not always result in anomalous diet-consumer nitrogen isotope fractionation, since the recycling process is closed or nearly closed with respect to nitrogen isotopes.

A fatal cardiac complication can occasionally present in malnourished patients during refeeding; this is known as refeeding syndrome. However, to our knowledge, hyperglycemia preceding torsades de pointes with QT prolongation during refeeding has not been reported. In the present study, we present a case in which hyperglycemia preceded torsades de pointes with QT prolongation during refeeding. The aim of this study was to determine the possible mechanism underlying QT prolongation during refeeding and indicate how to prevent it. A 32-y-old severely malnourished woman (body mass index 14.57 kg/m 2 ) was admitted to the intensive care unit of our institution after resuscitation from cardiopulmonary arrest due to ventricular fibrillation. She was diagnosed with anorexia nervosa. Although no obvious electrolyte abnormalities were observed, her blood glucose level was 11 mg/dL. A 12-lead electrocardiogram at admission showed sinus rhythm with normal QT interval (QTc 0.448). Forty mL of 50% glucose (containing 20 g of glucose) was intravenously injected, followed by a drip infusion of glucose to maintain blood glucose level within normal range. After 9 h, the patient's blood glucose level increased to 569 mg/dL. However, after 38 h, an episode of marked QT prolongation (QTc 0.931) followed by torsades de pointes developed. Hyperglycemia during refeeding can present with QT prolongation; consequently, monitoring blood glucose levels may be useful in avoiding hyperglycemia, which can result in QT prolongation. Furthermore, additional monitoring of QT intervals using a 12-lead electrocardiogram should allow the early detection of QT prolongation when glucose solution is administered to a malnourished patient with (severe) hypoglycemia.

Neuropsychiatric manifestations and brain atrophy of unknown etiology are common and severe complications of systemic lupus erythematosus (SLE). An autoantibody that binds to N-methyl-D-aspartate (NMDA) receptor NR2 has been proposed as a key factor in the etiology of central nervous system (CNS) SLE. This hypothesis was supported by evidence suggesting memantine (MEM), an uncompetitive NMDA receptor antagonist, prevents behavioral dysfunction and brain pathology in healthy mice immunized with a peptide similar to an epitope on the NR2 receptor. Given that SLE is a chronic condition, we presently examine the effects of MEM in MRL/lpr mice, which develop behavioral deficits alongside SLE-like disease. A broad behavioral battery and 7-Tesla MRI were used to examine whether prolonged treatment with MEM (~25 mg/kg b.w. in drinking water) prevents CNS involvement in this spontaneous model of SLE. Although MEM increased novel object exploration in MRL/lpr mice, it did not show other beneficial, substrain-specific effects. Conversely, MEM was detrimental to spontaneous activity in control MRL +/+ mice and had a negative effect on body mass gain. Similarly, MRI revealed comparable increases in the volume of periventricular structures in MEM-treated groups. Sustained exposure to MEM affects body growth, brain morphology, and behavior primarily by pharmacological, and not autoimmunity-dependant mechanisms. Substrain-specific improvement in exploratory behavior of MEM-treated MRL/lpr mice may indicate that the NMDA system is merely a constituent of a complex pathogenenic cascade. However, it was evident that chronic administration of MEM is unable to completely prevent the development of a CNS SLE-like syndrome.

The present study extends our previous work characterizing the behavioral features of autistic-spectrum disorder (ASD) in Down syndrome (DS) using the Aberrant Behavior Checklist (ABC) and Autism Behavior Checklist (AutBehav). We examined which specific behaviors distinguished the behavioral phenotype of DS + ASD from other aberrant behavior disorders in DS, by determining the relative contribution of ABC and AutBehav subscales and items to the diagnosis of ASD. A total of 127 subjects (aged 2-24 years; mean age: 8.4 years; approximately 70% male), comprising: a cohort of 64 children and adolescents with DS and co-morbid ASD (DS + ASD), 19 with DS and stereotypic movement disorder (DS + SMD), 18 with DS and disruptive behaviors (DS + DB), and 26 with DS and no co-morbid behavior disorders (DS + none) were examined using the aforementioned measures of aberrant behavior. We found that subjects with DS + ASD showed the most severe aberrant behavior, especially stereotypy compared to DS + none and lethargy/social withdrawal and relating problems compared to DS + SMD. Specifically, relatively simple stereotypic behavior differentiated DS + ASD from DS + DB, whereas odd/bizarre stereotypic and anxious behavior characterized DS + ASD relative to DS + SMD and DS + none. Additionally, in a subset of subjects with DS + ASD and anxiety, social withdrawal was particularly pronounced. Overall, our findings indicate that a diagnosis of DS + ASD represents a distinctive set of aberrant behaviors marked by characteristic odd/bizarre stereotypic behavior, anxiety, and social withdrawal.

Full Text Available Background: Pazopanib (PZP may induce prolonged cardiac repolarization and proarrhythmic effects, similarly to other tyrosine kinase inhibitors. Objectives: To demonstrate PZP-induced prolonged cardiac repolarization and proarrhythmic electrophysiological effects and to investigate possible preventive effects of metoprolol and diltiazem on ECG changes (prolonged QT in an experimental rat model. Methods: Twenty-four Sprague-Dawley adult male rats were randomly assigned to 4 groups (n = 6. The first group (normal group received 4 mL of tap water and the other groups received 100 mg/kg of PZP (Votrient® tablet perorally, via orogastric tubes. After 3 hours, the following solutions were intraperitoneally administered to the animals: physiological saline solution (SP, to the normal group and to the second group (control-PZP+SP group; 1 mg/kg metoprolol (Beloc, Ampule, AstraZeneca, to the third group (PZP+metoprolol group; and 1mg/kg diltiazem (Diltiazem, Mustafa Nevzat, to the fourth group (PZP+diltiazem group. One hour after, and under anesthesia, QTc was calculated by recording ECG on lead I. Results: The mean QTc interval values were as follows: normal group, 99.93 ± 3.62 ms; control-PZP+SP group, 131.23 ± 12.21 ms; PZP+metoprolol group, 89.36 ± 3.61 ms; and PZP+diltiazem group, 88.86 ± 4.04 ms. Both PZP+metoprolol and PZP+diltiazem groups had significantly shorter QTc intervals compared to the control-PZP+SP group (p < 0.001. Conclusion: Both metoprolol and diltiazem prevented PZP-induced QT interval prolongation. These drugs may provide a promising prophylactic strategy for the prolonged QTc interval associated with tyrosine kinase inhibitor use.

Using the Single Prolonged Stress Model to Examine the Pathophysiology of PTSD

Full Text Available The endurance of memories of emotionally arousing events serves the adaptive role of minimizing future exposure to danger and reinforcing rewarding behaviors. However, following a traumatic event, a subset of individuals suffers from persistent pathological symptoms such as those seen in posttraumatic stress disorder (PTSD. Despite the availability of pharmacological treatments and evidence-based cognitive behavioral therapy, a considerable number of PTSD patients do not respond to the treatment, or show partial remission and relapse of the symptoms. In controlled laboratory studies, PTSD patients show deficient ability to extinguish conditioned fear. Failure to extinguish learned fear could be responsible for the persistence of PTSD symptoms such as elevated anxiety, arousal, and avoidance. It may also explain the high non-response and dropout rates seen during treatment. Animal models are useful for understanding the pathophysiology of the disorder and the development of new treatments. This review examines studies in a rodent model of PTSD with the goal of identifying behavioral and physiological factors that predispose individuals to PTSD symptoms. Single prolonged stress (SPS is a frequently used rat model of PTSD that involves exposure to several successive stressors. SPS rats show PTSD-like symptoms, including impaired extinction of conditioned fear. Since its development by the Liberzon lab in 1997, the SPS model has been referred to by more than 200 published papers. Here we consider the findings of these studies and unresolved questions that may be investigated using the model.

The deleterious functional implications of motivation deficits in psychosis have generated interest in examining dimensions of the construct. However, there remains a paucity of data regarding whether dimensions of motivation differ over the course of psychosis. Therefore, this study examined two motivation dimensions, trait-like intrinsic motivation, and the negative symptom of amotivation, and tested the impact of illness phase on the 1) levels of these dimensions and 2) relationship between these dimensions. Participants with first episode psychosis (FEP; n=40) and prolonged psychosis (n=66) completed clinician-rated measures of intrinsic motivation and amotivation. Analyses revealed that when controlling for group differences in gender and education, the FEP group had significantly more intrinsic motivation and lower amotivation than the prolonged psychosis group. Moreover, intrinsic motivation was negatively correlated with amotivation in both FEP and prolonged psychosis, but the magnitude of the relationship did not statistically differ between groups. These findings suggest that motivation deficits are more severe later in the course of psychosis and that low intrinsic motivation may be partially independent of amotivation in both first episode and prolonged psychosis. Clinically, these results highlight the importance of targeting motivation in early intervention services. Copyright © 2015 Elsevier B.V. All rights reserved.

Full Text Available We present a case of acute mesenteric venous thrombosis after a long distance flight in a traveller presenting with abdominal pain, diarrhoea and vomiting within 48 h of prolonged immobility situation. Venous thrombosis in the lower limbs and venous thromboembolism has been clearly associated with prolonged air travel (economy class syndrome. Thrombosis was diagnosed by computed tomography of the abdomen, and after starting anticoagulant therapy with acenocumarol, symptoms yielded completely in a few weeks. The study of thrombophilia was negative, although the existence of two first-degree relatives (mother and grandmother with a history of venous thrombosis with a history of venous thrombosis makes it likely a situation of inherited thrombophilia. Although exceptional, mesenteric venous thrombosis should be considered in travellers with acute abdominal pain after prolonged air travel when there are thrombophilic conditions.

In this paper, the dose absorbed by mice was evaluated as a preliminary study of the late effects of prolonged continuous irradiation of mice with low-dose rate ionizing radiation. Eight-week-old male and female SPF C3H/HeN mice in three irradiation rooms were exposed to irradiation at 8000, 400, and 20 mGy, respectively, using a {sup 137}Cs {gamma}-source. Nine racks were arranged in a circle approximately 2.5 m from the source in each room, and 10 cages were arranged on the 4 shelves of each rack. Dose distributions, such as in air at the source level, in the three rooms were estimated by using ionization chambers, and the absorbed dose distributions in the room and relative dose distributions in the cages in relation to the distance of the cage center were examined. The mean abdomen doses of the mice measured by TLD were compared with the absorbed doses in the cages. The absorbed dose distributions showed not only inverse-inverse-square-law behavior with distance from the source, but geometric symmetry in every room. The inherent scattering and absorption in each room are responsible for such behavior and asymmetry. Comparison of relative dose distributions revealed cage positions that are not suitable for experiments with high precision doses, but all positions can be used for prolonged continuous irradiation experiments if the position of the cages is rotated regularly. The mean abdomen doses of the mice were similar in each cage. The mean abdomen doses of the mice and the absorbed doses in a cage were almost the same in all cages. Except for errors concerning the positions of the racks and cages, the uncertainties in the exposure doses were estimated to be about {+-}12% for 8000 mGy group, 17% for 400 mGy group, and 35% for 20 mGy group.

Full Text Available Background: Prolonged endotracheal intubation is a growing method for supporting ventilation in patients who require intensive care. Despite considerable advancement in endotracheal intubation, this method still has some complications; the most important is laryngo-tracheal injuries. Methods: Over a 2-year period, this retrospective study was conducted on 57 patients with history of prolonged intubation who were referred to the ENT Department of Amir Alam Hospital. For each patient, a complete evaluation including history, physical examination, and direct laryngoscopy and bronchoscopy was done under general anesthesia. Results: Fifty-seven patients (44 male; mean age, 23.014.7 years were studied. Mean intubation period was 15.88 days. The most common presenting symptom was dyspnea (62%. Head trauma was responsible for most cases of intubation (72.4%. The most common types of tracheal and laryngeal lesions were tracheal (56.9% and subglottic (55.2% stenosis, respectively. Mean length of tracheal stenosis was 0.810.83 cm. There was a statistically significant relationship between length of tracheal stenosis and intubation period (P=0.0001 but no relation was observed between tracheal stenosis and age, sex, and etiology of intubation (All P=NS. Among the glottic lesions, inter- arytenoids adhesion was the most common lesion (25.9%. No statistically significant relation was found between glottic and subglottic lesions and age, sex and intubation period (all P=NS. Length of stenosis and intubation period was significantly greater in tracheal/ subglottic lesions than those in glottic/ supraglottic lesions (all P=NS. Conclusion: After prolonged endotracheal intubation, laryngo-tracheal lesions had no relation with patient’s age, sex, and cause of intubation.There was direct relation between length of tracheal stenosis and intubation period. Glottic lesions were more commonly observed in head trauma patients. Lesion length and intubation

The aim of this study was to assess the utility of quantitative computed tomography-based grading of emphysema for predicting prolonged air leak after thoracoscopic lobectomy. A consecutive series of 284 patients undergoing thoracoscopic lobectomy for lung cancer was retrospectively reviewed. Prolonged air leak was defined as air leaks lasting 7 days or longer. The grade of emphysema (emphysema index) was defined by the proportion of the emphysematous lung volume (less than -910 HU) to the total lung volume (-600 to -1,024 HU) by a computer-assisted histogram analysis of whole-lung computed tomography scans. The mean length of chest tube drainage was 1.5 days. Fifteen patients (5.3%) presented with prolonged air leak. According to a receiver-operating characteristics curve analysis, the emphysema index was the best predictor of prolonged air leak, with an area under the curve of 0.85 (95% confidence interval: 0.73 to 0.98). An emphysema index of 35% or greater was the best cutoff value for predicting prolonged air leak, with a negative predictive value of 0.99. The emphysema index was the only significant predictor for the length of postoperative chest tube drainage among conventional variables, including the pulmonary function and resected lobe, in both univariate and multivariate analyses. Prolonged air leak resulted in an increased duration of hospitalization (p leak that adversely influences early postoperative outcomes. We must take new measures against prolonged air leak in quantitative computed tomography-based high-risk patients. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

2000-09-01

The aim of this study was to examine the pattern of comorbidity among obsessive-compulsive personality disorder (OCPD) and other personality disorders (PDs) in a sample of 400 psychiatric inpatients. PDs were assessed using the Semistructured Clinical Interview for DSM-III-R Personality Disorders (SCID-II). Odds ratios (ORs) were calculated to determine significant comorbidity among OCPD and other axis II disorders. The most elevated odds ratios were found for the cooccurrence of OCPD with cluster A PDs (the "odd" PDs, or paranoid and schizoid PDs). These results are consistent with those of previous studies showing a higher cooccurrence of OCPD with cluster A than with cluster C ("anxious") PDs. In light of these observations, issues associated with the nosologic status of OCPD within the Diagnostic and Statistical Manual of Mental Disorders clustering system remain unsettled.

Mortality among the small percentage of cardiac surgery patients receiving prolonged mechanical ventilation is high, but this issue appears to be inadequately addressed in guidelines. This study is a retrospective analysis of prospective, multi-center, and observational study in Spain including all adults undergoing cardiac surgery in 3 Andalusian hospitals between June 2008 and December 2012. The study included 3,588 adults with mean ± SD age of 63.5 ± 12.8 y and with median (interquartile range) EuroSCORE of 5 (3-7) points. Prolonged mechanical ventilation (> 24 h) was required by 415 subjects (11.6%), with ICU mortality of 44.3% (184 subjects), and was not required by 3,173 subjects (88.4%), with ICU mortality of 3.1% (99 subjects, P mechanical ventilation was associated with more complications and was required by 4.5% of subjects with a EuroSCORE 10. In the multivariable analysis, ICU mortality was associated with illness severity, duration of bypass surgery, surgery type, and prolonged mechanical ventilation (odds ratio 15.19, 95% CI 11.56-22.09). The main cause of death was multiple organ failure and sepsis in subjects who required prolonged mechanical ventilation (50.3%) and cardiogenic shock in those who did not (59.2%). Prolonged postoperative mechanical ventilation was required by 10-20% of cardiac surgery subjects, who constitute a specific group that represents most of the postoperative mortality, which is associated with multiple organ failure and sepsis.

Full Text Available Background. Neonatal jaundice is one of the urgent problems in neonatology. There is a tendency to increase the incidence of prolonged jaundice. The aim of our study was to explore the features of history, anthropometric data and some liver functions in children with prolonged jaundice. Materials and methods. The study involved 111 children with prolonged jaundice aged from 3 weeks to 3 months. In all children with prolonged jaundice, we have examined complete blood count, urinalysis, blood chemistry (determination of total bilirubin and fractions, total protein, albumin, glucose and used instrumental methods of examination — ultrasound of the abdominal cavity and cranial ultrasonography, electrocardiography. Most children with prolonged jaundice were breastfed and were term infants. Results. Indicators of physical development at birth (body weight, body length, head circumference, chest circumference in children with prolonged jaundice and in healthy children had not statistically significant differences. Neonatal jaundice was prolonged in children, who were born from the first pregnancy, — 60 children (54.1 %. A high level of total and indirect bilirubin was accompanied by a low level of albumin in the blood serum of children with prolonged jaundice. Protein-synthesis function of the liver was reduced in children with prolonged jaundice.

This study aims to identify factors that predict the mental health care referral of anxious children. In total, 249 children and families, aged 8-13 years, participated: 73 children were referred with anxiety disorders to mental health care [mean (M) age = 10.28, standard deviation (SD) = 1.35], 176 non-referred anxious children recruited in primary schools (M age = 9.94, SD = 1.22). Child anxiety and other disorders were assessed with semi-structured interviews. Child anxiety symptoms, behavioural problems, parental anxiety, the parenting styles overprotection, autonomy encouragement, rejection, and the family functioning dimensions control and relational functioning, were assessed with child, father and mother report on questionnaires. The summed interference rating of children's anxiety disorders was a predictor of referral, consistent over child and parent reports, but not comorbidity. Most family and parenting variables did not predict referral, nor differed between the referred and non-referred sample. Contrary to our hypothesis, maternal self-reported anxiety decreased the odds of referral and child reported parental autonomy granting increased, while child reported overprotection decreased the odds of referral. The impairment for the child due to the number and severity of their anxiety disorder(s) is, based on child, mother and father report associated with referral. This indicates that those who need it most, receive clinical treatment. Copyright © 2014 John Wiley & Sons, Ltd.

Electrocardiographic PR interval prolongation is considered a benign condition, but recent studies have challenged the notion by demonstrating that prolonged PR interval is associated with an increased risk of atrial fibrillation (AF). The purpose of this study was to perform a meta-analysis of prospective cohort studies to evaluate the evidence supporting an association of prolonged PR interval with AF incidence. We searched the MEDLINE and EMBASE database (from inception to May 2014) supplemented by manual searches of references of relevant retrieved articles. Prospective cohort studies were included with hazard ratio (HR) of prolonged PR interval for incident AF. The search strategy yielded 6 cohort studies meeting eligibility criteria. A total of 328,932 participants were included, with 14,191 participants suffering from AF during follow-up. Pooled HRs of prolonged PR interval for incident AF was 1.30 (95% CI: 1.13 to 1.49) using random-effect model (I(2) = 30%). There was a significant difference of combined HRs between studies with and without adjustment for taking of AV nodal blocking agents in subgroup analysis. Sensitivity analysis supported the robustness of the results. Prolonged PR interval is not a totally benign condition but an independent risk factor for AF incidence. The mechanisms underlying the association of prolonged PR interval with AF incidence need further research. © 2014 Wiley Periodicals, Inc.

CD36 is a member of the class B scavenger receptor family of cell surface proteins, which plays a major role in fatty acid, glucose and lipid metabolism. Besides, CD36 functions as a microglial surface receptor for amyloid beta peptide. Regarding this, we suggest CD36 might also contribute to neuropsychiatric disease. The aim of this study was to achieve a behavioral phenotype of CD36 knockout (CD36(-/-)) mice. We characterized the behavior of CD36(-/-) mice and C57BL/6J mice by subjecting them to a series of tests, which include SHIRPA primary behavioral screen test, 1% sucrose preference test, elevated plus-maze test, open-field test and forced swimming test. The results showed that CD36(-/-) mice traversed more squares, emitted more defecation, exhibited higher tail elevation and had more aggressive behaviors than C57BL/6J mice. The CD36(-/-) mice spent more time and traveled longer distance in periphery zone in the open-field test. Meanwhile, the numbers that CD36(-/-) mice entered in the open arms of elevated plus-maze were reduced. These findings suggest that CD36(-/-) mice present an anxious phenotype and might be involved in neuropsychiatric disorders. Copyright © 2015. Published by Elsevier B.V.

Temporal lobe epileptic signs and correlative behaviors displayed by normal populations.

With regard to epileptic signs and correlative behaviors, one hypothesis is that the experiences and nonconvulsive behaviors of patients with electrical foci within the temporal lobe are also displayed, but with less intensity, by normal people. If this is correct, then there should be quantitative relationships between the numbers of major complex partial epileptic signs (CPES) and the occurrence of other frequent clinical experiences and behaviors. An inventory to answer this question was developed. Over a 3-year period, 414 (6 groups) university students were administered an inventory that included themes of CPES as well as control and information items. Strong correlations were consistently found between CPES scores and reports of paranormal (mystical, with religious overtones) experiences and "a sense of presence." Results from three personality (CPI, MMPI, and IPAT anxiety) inventories clearly demonstrated similar profiles. In addition to being more anxious, people who displayed higher CPES scores were more suspicious, aloof, stereotyped in their behavior, ruminative (overthinking), intellectually inefficient, and overly judgmental. CPES scores were significantly (p less than .001) correlated with the schizophrenia and mania subscales of the MMPI. The results suggest that functional hyperconnectionism of cortical-limbic systems within the brain may be more prevalent in the normal population than previously suspected.

A nasal pressure transducer, which is used to study nocturnal airflow, also provides information about the inspiratory flow waveform. A round flow shape is presented during normal breathing. A flattened, non-round shape is found during hypopneas and it can also appear in prolonged episodes. The significance of this prolonged flow limitation is still not established. A tracheal sound spectrum has been analyzed further in order to achieve additional information about breathing during sleep. Increased sound frequencies over 500 Hz have been connected to obstruction of the upper airway. The aim of the present study was to examine the tracheal sound signal content of prolonged flow limitation and to find out whether prolonged flow limitation would consist of abundant high frequency activity. Sleep recordings of 36 consecutive patients were examined. The tracheal sound spectral analysis was performed on 10 min episodes of prolonged flow limitation, normal breathing and periodic apnea-hypopnea breathing. The highest total spectral amplitude, implicating loudest sounds, occurred during flow-limited breathing which also presented loudest sounds in all frequency bands above 100 Hz. In addition, the tracheal sound signal during flow-limited breathing constituted proportionally more high frequency activities compared to normal breathing and even periodic apnea-hypopnea breathing

The association of prolonged neonatal jaundice and hypoglycaemia may be secondary to an endocrinological disease. Pituitary insufficiency and primary adrenal insufficiency are the most likely endocrine diseases that need to be ruled out. We retrospectively analysed the clinical and laboratory characteristics of thirteen patients referred to the Hospital de Niños Ricardo Gutiérrez between years 2003 and 2008 due to prolonged neonatal jaundice and hypoglycaemia secondary to pituitary insufficiency in twelve patients, and in one secondary to primary adrenal insufficiency. All patients had a history of neonatal hypoglycaemia. Ten patients had conjugated hyperbilirubinaemia and six also had elevated transaminases. Combined pituitary hormone deficiency was observed in the twelve hypopituitarism patients. Hormonal replacement normalised liver function and resolved the prolonged jaundice in all the patients. None of them underwent liver biopsy. Hypoglycaemia also remitted after hormonal therapy. Prolonged or cholestatic jaundice associated with neonatal hypoglycaemia is highly likely to be due to pituitary hormone deficiency or primary adrenal insufficiency. Early diagnosis and treatment of these children reverts the prolonged jaundice and prevents morbidity and mortality due to recurrent hypoglycaemia and hormone deficiencies.

To determine the association of QTc interval prolongation with ventricular arrhythmias in patients with chronic heart failure. Study Design: Descriptive study. Place and Duration of Study: This study was conducted at Armed Forces Institute of Cardiology/National Institute of Heart Diseases, Rawalpindi, Pakistan from April 2013 to August 2013. Patients and Methods: Fifty three heart failure patients were monitored for 48 hours using ambulatory holter electrocardiography recorders. Digital ECG data was analyzed for QTc interval along with frequency and severity of arrhythmias. Association of prolonged QTc interval with ventricular arrhythmias and severity of arrhythmias was analyzed. Results: Cardiac arrhythmias were observed in 79.2% patients. QT analysis revealed that 69.8% patients had prolonged QTc interval, 86.4% patients with prolonged QTc had ventricular arrhythmias. Of these 66% patients were found to have severe ventricular arrhythmias. Comparison of mean QTc interval of our study population with a reference value showed significantly higher QTc interval of our study group than the test value. Conclusion: Arrhythmia frequency and severity significantly increases with an increase in QTc interval in heart failure demonstrating association of prolonged QTc interval with high risk of severe ventricular arrhythmias and sudden cardiac death in chronic heart failure.

Monocyte Trafficking to the Brain with Stress and Inflammation: A Novel Axis of Immune-to-Brain Communication that Influences Mood and Behavior

Directory of Open Access Journals (Sweden)

Eric S Wohleb

2015-01-01

Full Text Available Psychological stressors cause physiological, immunological, and behavioral alterations in humans and rodents that can be maladaptive and negatively affect quality of life. Several lines of evidence indicate that psychological stress disrupts key functional interactions between the immune system and brain that ultimately affects mood and behavior. For example, activation of microglia, the resident innate immune cells of the brain, has been implicated as a key regulator of mood and behavior in the context of prolonged exposure to psychological stress. Emerging evidence implicates a novel neuroimmune circuit involving microglia activation and sympathetic outflow to the peripheral immune system that further reinforces stress-related behaviors by facilitating the recruitment of inflammatory monocytes to the brain. Evidence from various rodent models, including repeated social defeat (RSD, revealed that trafficking of monocytes to the brain promoted the establishment of anxiety-like behaviors following prolonged stress exposure. In addition, new evidence implicates monocyte trafficking from the spleen to the brain as key regulator of recurring anxiety following exposure to prolonged stress. The purpose of this review is to discuss mechanisms that cause stress-induced monocyte re-distribution in the brain and how dynamic interactions between microglia, endothelial cells, and brain macrophages lead to maladaptive behavioral responses.

We aimed to evaluate the Child Behavior Checklist (CBCL) profiles in youths with bipolar and depressive disorders. Seventy-four subjects with a mean age of 14.9±1.6years (36 boys) with mood disorders and their parents were recruited from September 2011 to June 2013 in the Department of Psychiatry, Asan Medical Center, Seoul, Korea. Diagnosis of mood disorder and comorbid psychiatric disorder was confirmed by child psychiatrists using the Schedule for Affective Disorders and Schizophrenia for School Age Children - Present and Lifetime version (K-SADS-PL). The parents of the subjects completed the Parent General Behavior Inventory-10-item Mania Scale (P-GBI-10M), Parent-version of Mood Disorder Questionnaire (P-MDQ), ADHD rating scale (ARS) and CBCL. The adolescents completed the 76-item Adolescent General Behavior Inventory (A-GBI), Beck Depression Inventory (BDI), and Adolescent-version of Mood Disorder Questionnaire (A-MDQ). When adjusted for gender and the comorbidity with ADHD, the Withdrawn and Anxious/Depressed subscale scores of the CBCL were higher in subjects with bipolar disorder than in those with depressive disorder. Higher scores of A-GBI Depressive subscale, A-MDQ and BDI were shown in subjects with bipolar disorder than in those with depressive disorder. There was no significant difference on CBCL-DP, P-GBI-10M, P-MDQ, A-GBI Hypomanic/Biphasic subscale and ARS between two groups. All eight subscales of the CBCL positively correlated with the P-GBI-10M and P-MDQ scores, and seven of all eight subscales of the CBCL positively correlated with A-GBI Depressive and Hypomanic/Biphasic subscales. The BDI score was positively associated with the Withdrawn, Somatic Complaints, Anxious/Depressed, and Social Problems subscale scores. CBCL-DP score was strongly correlated with manic/hypomanic symptoms measured by P-GBI-10M and P-MDQ (r=0.771 and 0.826). This study suggests that the CBCL could be used for measuring mood symptoms and combined psychopathology

This study aimed to determine the frequency of B. pertussis infection among Turkish children with prolonged cough. Nasopharyngeal specimens were collected from 7-18 year old children, presenting with prolonged cough of two to four weeks' duration. Specimens were examined for B. pertussis by PCR. Of 101 children with prolonged cough, 20 (19.8%) had a positive PCR testing for B. pertussis. Children who were vaccinated ≥5 years previously had a 6.13-fold higher risk of PCR-confirmed pertussis than those who were vaccinated pertussis (paroxysmal cough, whooping and post-tussive vomiting) were seen in 30%, 15% and 25% of the patients with positive PCR, respectively; 55% of them had only a prolonged cough without any classic symptoms. Pertussis is common among Turkish children with prolonged cough, even after implementation of a fifth dose of pertussis vaccination and despite high vaccination coverage.

DSM-5 included criteria for an anxious distress specifier for major depressive disorder (MDD). In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project we examined whether a measure of the specifier, the DSM-5 Anxious Distress Specifier Interview (DADSI), was as valid as the Hamilton Anxiety Scale (HAMA) as a measure of the severity of anxiety in depressed patients. Two hundred three psychiatric patients with MDD were interviewed by trained diagnostic raters who administered the Structured Clinical Interview for DSM-IV (SCID) supplemented with questions to rate the DADSI, HAMA, and Hamilton Depression Rating Scale (HAMD). The patients completed self-report measures of depression, anxiety, and irritability. Sensitivity to change was examined in 30 patients. The DADSI and HAMA were significantly correlated (r = 0.60, p anxiety than with measures of the other symptom domains. The HAMD was significantly more highly correlated with the HAMA than with the DADSI. For each anxiety disorder, patients with the disorder scored significantly higher on both the DADSI and HAMA than did patients with no current anxiety disorder. A large effect size of treatment was found for both measures (DADSI: d = 1.48; HAMA: d = 1.37). Both the DADSI and HAMA were valid measures of anxiety severity in depressed patients, though the HAMA was more highly confounded with measures of depression than the DADSI. The DADSI is briefer than the HAMA, and may be more feasible to use in clinical practice. Copyright © 2017 Elsevier Ltd. All rights reserved.

BACKGROUND: The long-term neurotoxicity of 3,4-methylenedioxymethamphetamine (MDMA) mainly caused by repeated exposure to MDMA or a single big dose of MDMA, which results in degeneration of serotonin terminal of central nervous system, and someone believe that the great release of serotonin transmitter in central nervous system will lead to anxious mood.OBJECTIVE: To observe the changes of anxiety related behaviors in rats after single administration of different doses of MDMA.DESIGN: A randomized control study.SETTING: Laboratory of Psychopharmacology of the Mental Health Center, West China Hospital of Sichuan University.MATERIALS: Thirty male adult Wistar rats, weighing (251.3±18.34) g, were used. MDMA were obtained from the National Institute for the Control of Pharmaceutical and Biological Products, and dissolved in saline. All the doses of the drug were administered in a volume of 1 mg/kg.METHODS: The experiment was carried out in the Laboratory of Psychopharmacology of the Mental Health Center, West China Hospital of Sichuan University in July 2003. ①The rats were randomly divided into control group (n=6) and experimental group (n=24), and then those in the latter were randomly assigned into four subgroups of MDMA 3, 5, 10 and 20 mg/kg groups, with 6 rats in each, which were administrated by single intraperitoneal injection of MDMA 3, 5, 10 and 20 mg/kg respectively, and those in the control group were administrated by single intraperitoneal injection of saline of the same volume. ② The open field test,elevated plus-maze test and social interaction test were performed immediately after administration. For the open field test, the apparatus was situated in a darkened room, illuminated by a single 60 W white light bulb located approximately 60 cm above the center of the open field. Before administration, all the rats were placed into the open field to be familiar with the open field for 5 minutes. They were observed for 45 minutes after administration. The

Introduction TV viewing is the most prevalent sedentary behavior and is associated with increased risk of cardiovascular disease and cancer mortality, but the association with other leading causes of death is unknown. This study examined the association between TV viewing and leading causes of death in the U.S. Methods A prospective cohort of 221,426 individuals (57% male) aged 50–71 years who were free of chronic disease at baseline (1995–1996), 93% white, with an average BMI of 26.7 (SD=4.4) kg/m2 were included. Participants self-reported TV viewing at baseline and were followed until death or December 31, 2011. Hazard ratios (HRs) and 95% CIs for TV viewing and cause-specific mortality were estimated using Cox proportional hazards regression. Analyses were conducted in 2014–2015. Results After an average follow-up of 14.1 years, adjusted mortality risk for a 2-hour/day increase in TV viewing was significantly higher for the following causes of death (HR [95% CI]): cancer (1.07 [1.03, 1.11); heart disease (1.23 [1.17, 1.29]); chronic obstructive pulmonary disease (1.28 [1.14, 1.43]); diabetes (1.56 [1.33, 1.83]); influenza/pneumonia (1.24 [1.02, 1.50]); Parkinson disease (1.35 [1.11, 1.65]); liver disease (1.33 [1.05, 1.67]); and suicide (1.43 [1.10, 1.85]. Mortality associations persisted in stratified analyses with important potential confounders, reducing causation concerns. Conclusions This study shows the breadth of mortality outcomes associated with prolonged TV viewing, and identifies novel associations for several leading causes of death. TV viewing is a prevalent discretionary behavior that may be a more important target for public health intervention than previously recognized.

Dellmann, Thomas

2018-07-01

Although many single factors of prolonged grief have been identified in the literature, a comprehensive understanding of predictors is still lacking. This article argues that shame and low self-esteem, present risk factors in prolonged grief after spousal loss, based on a review of correlational studies. Using a practitioner-scientist approach, a developmental model of shame as a core factor in prolonged grief is proposed, outlining the progression from childhood relational trauma, to insecure attachment, shame, self-esteem contingent on spousal approval to eventual prolonged grief.

Although risk-taking has been studied from a developmental perspective, no study has examined how anxiety, age, risk-valence and social context interact to modulate decision-making in youths. This study probes this question using a risk-taking task, the Stunt Task, in clinically anxious children (n = 17, 10 F, age = 8.3-12.1 years), healthy children (n = 13, 4 F, age = 9.3-12.2 years), clinically anxious adolescents (n = 18, 6 F, age = 12.3-17.7 years), and healthy adolescents (n =14, 10 F, age = 12.5-17.3 years). Social context was manipulated: in one condition, participants were led to believe that a group of peers were observing and judging their performance (peer-judge), while, in the other condition, they were led to believe that peers were not observing them (control). Only anxious children showed an influence of social context on their risk-taking behavior. Specifically, anxious children bet significantly less and had slower reaction times (RT) during the peer-judge than control condition. However, across social conditions, risk-valence modulated RT differently in function of age and diagnosis. Anxious children were slower on the positive-valence risky trial, whereas anxious adolescents were slower on the negative-valence risky trials relative to their respective healthy peers. In conclusion, clinically anxious children were the only group that was sensitive (risk-averse) to the effect of a negative peer-judge context. The negative peer-judge context did not affect risky decision-making in adolescents, whether they were anxious or healthy. Future work using a stronger aversive social context might be more effective at influencing risky behavior in this age group.

One of the hypotheses about the pathogenesis of posttraumatic stress disorder (PTSD) is the dysfunction of serotonin (5-HT) neurotransmission. While certain 5-HT receptor subtypes are likely critical for the symptoms of PTSD, few studies have examined the role of 5-HT 3 receptor in the development of PTSD, even though 5-HT 3 receptor is critical for contextual fear extinction and anxiety-like behavior. Therefore, we hypothesized that stimulation of 5-HT 3 receptor in the dorsal hippocampus (DH) could prevent hippocampal autophagy and the development of PTSD-like behavior in animals. To this end, we infused SR57227, selective 5-HT 3 agonist, into the DH after a single prolonged stress (SPS) treatment in rats. Three weeks later, we evaluated the effects of this pharmacological treatment on anxiety-related behaviors and extinction of contextual fear memory. We also accessed hippocampal autophagy and the expression of 5-HT 3A subunit, Beclin-1, LC3-I, and LC3-II in the DH. We found that SPS treatment did not alter anxiety-related behaviors but prolonged the extinction of contextual fear memory, and such a behavioral phenomenon was correlated with increased hippocampal autophagy, decreased 5-HT 3A expression, and increased expression of Beclin-1 and LC3-II/LC3-I ratio in the DH. Furthermore, intraDH infusions of SR57227 dose-dependently promoted the extinction of contextual fear memory, prevented hippocampal autophagy, and decreased expression of Beclin-1 and LC3-II/LC3-I ratio in the DH. These results indicated that 5-HT 3 receptor in the hippocampus may play a critical role in the pathogenesis of hippocampal autophagy, and is likely involved in the pathophysiology of PTSD.

“HOW DO YOU FEEL?”: EMOTIONS EXHIBITED WHILE PLAYING COMPUTER GAMES AND THEIR RELATIONSHIP TO GAMING BEHAVIORS

Full Text Available This descriptive study utilized a validated questionnaire to determine the emotions exhibited by computer gamers in cyber cafés. We determined that gamers exhibited both positive and negative emotions while playing games. We observed that gamers were inclined to be more anxious about being defeated in a game as gaming became frequent and length of years spent playing games increased. They also had the tendency to become more stressed when length of years spent playing games increased. On the other hand, other gaming behaviors were not significantly related to other emotions. We concluded that not all emotions exhibited by gamers while playing computer games could be attributed to their gaming behaviors. We recommend that other emotions such as anger, frustration, boredom, amusement, etc. be included in future research.

F247. INTERNALIZED STIGMA HAS A STRONGER RELATIONSHIP WITH INTRINSIC MOTIVATION COMPARED TO AMOTIVATION IN EARLY PHASE AND PROLONGED SCHIZOPHRENIA

Abstract Background Motivation deficits predict decreased functioning in schizophrenia. Recent work suggests deficits reflect challenges in separate domains: intrinsic motivation (one’s internal drive to engage in a behavior out of enjoyment or interest) and amotivation (one’s broader decrease in motivated behavior linked to avolition and anhedonia). Internalized stigma is another determinant of functioning for people with schizophrenia that may impact motivation. However, little is known about these relationships, including which aspects of motivation it may impact nor when these links emerge. Identifying the link between these constructs may help to identify whether internalized stigma may be a novel treatment target to facilitate improvements in motivation. Methods Forty adults with early phase schizophrenia and 66 adults with prolonged schizophrenia completed measures of internalized stigma, intrinsic motivation, and amotivation. Pearson’s correlations were examined followed by Fischer’s r-to-z transformations to compare differences in the magnitude of associations between internalized stigma and intrinsic motivation and internalized stigma and amotivation among the first episode and prolonged samples. Next, we conducted stepwise regressions to examine whether internalized stigma was associated with intrinsic motivation above and beyond associations with amotivation in each sample. Results In the early phase sample, the association between internalized stigma was greater with intrinsic motivation (r=-0.48, p=.00) compared to amotivation (r=0.27, p=0.10). Associations with internalized stigma in the prolonged sample were also greater with intrinsic motivation (r=-0.30, p=0.02) versus amotivation (r=0.19, p=0.12). The magnitude of the associations between internalized stigma and intrinsic motivation (z=1.03, p=0.15) and between internalized stigma and amotivation (z=0.41, p = 0.34) did not significantly differ when comparing phase 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.

Posttraumatic stress disorder (PTSD) is often comorbid with substance use disorders (SUD). Single prolonged stress (SPS) is a well-validated rat model of PTSD that provides a framework to investigate drug-induced behaviors as a preclinical model of the comorbidity. We hypothesized that cocaine sensitization and self-administration would be increased following exposure to SPS. Male Sprague-Dawley rats were exposed to SPS or control treatment. After SPS, cocaine (0, 10 or 20 mg/kg, i.p.) was administered for 5 consecutive days and locomotor activity was measured. Another cohort was assessed for cocaine self-administration (0.1 or 0.32 mg/kg/i.v.) after SPS. Rats were tested for acquisition, extinction and cue-induced reinstatement behaviors. Control animals showed a dose-dependent increase in cocaine-induced locomotor activity after acute cocaine whereas SPS rats did not. Using a sub-threshold sensitization paradigm, control rats did not exhibit enhanced locomotor activity at Day 5 and therefore did not develop behavioral sensitization, as expected. However, compared to control rats on Day 5 the locomotor response to 20mg/kg repeated cocaine was greatly enhanced in SPS-treated rats, which exhibited enhanced cocaine locomotor sensitization. The effect of SPS on locomotor activity was unique in that SPS did not modify cocaine self-administration behaviors under a simple schedule of reinforcement. These data show that SPS differentially affects cocaine-mediated behaviors causing no effect to cocaine self-administration, under a simple schedule of reinforcement, but significantly augmenting cocaine locomotor sensitization. These results suggest that SPS shares common neurocircuitry with stimulant-induced plasticity, but dissociable from that underlying psychostimulant-induced reinforcement. Copyright © 2015.

This study was performed to determine the effects of sodium bicarbonate injection during prolonged cardiopulmonary resuscitation (for >15 minutes). The retrospective cohort study consisted of adult patients who presented to the emergency department (ED) with the diagnosis of cardiac arrest in 2009. Data were retrieved from the institutional database. A total of 92 patients were enrolled in the study. Patients were divided into 2 groups based on whether they were treated (group1, n = 30) or not treated (group 2, n = 62) with sodium bicarbonate. There were no significant differences in demographic characteristics between groups. The median time interval between the administration of CPR and sodium bicarbonate injection was 36.0 minutes (IQR: 30.5-41.8 minutes). The median amount of bicarbonate injection was 100.2 mEq (IQR: 66.8-104.4). Patients who received a sodium bicarbonate injection during prolonged CPR had a higher percentage of return of spontaneous circulation, but not statistical significant (ROSC, 40.0% vs. 32.3%; P = .465). Sustained ROSC was achieved by 2 (6.7%) patients in the sodium bicarbonate treatment group, with no survival to discharge. No significant differences in vital signs after ROSC were detected between the 2 groups (heart rate, P = .124; systolic blood pressure, P = .094). Sodium bicarbonate injection during prolonged CPR was not associated with ROSC after adjust for variables by regression analysis (Table 3; P = .615; odds ratio, 1.270; 95% confidence interval: 0.501-3.219) The administration of sodium bicarbonate during prolonged CPR did not significantly improve the rate of ROSC in out-of-hospital cardiac arrest.

To investigate primiparous women's preferences for care during a prolonged latent phase of labour. A qualitative study based on focus groups and individual interviews and analysed with inductive content analysis. Sixteen primiparous women with a prolonged latent phase of labour >18 hours were interviewed in five focus groups (n = 11) or individually (n = 5). One main category emerged "Beyond normality - a need of individual adapted guidance in order to understand and manage an extended latent phase of labour" which covers the women's preferences during the prolonged latent phase. Five categories were generated from the data: "A welcoming manner and not being rejected", "Individually adapted care", "Important information which prepares for reality and coping", "Participation and need for feedback" and "Staying nearby the labour ward or being admitted for midwifery support". Women with a prolonged latent phase of labour sought to use their own resources, but their needs for professional support increased as time passed. A welcoming attitude from an available midwife during the latent phase created a feeling of security, and personally adapted care was perceived positively. Women with a prolonged latent phase of labour preferred woman-centred care. Midwives play an important role in supporting these women. Women's need for midwifery-support increases as the time spent in latent phase increases. Copyright © 2015 Elsevier B.V. All rights reserved.

2017-07-01

This study combined conceptual frameworks from health information seeking, appraisal theory of emotions, and social determinants of health literatures to examine how emotional states and education predict online health information seeking. Nationally representative data from the Health Information National Trends Survey (HINTS 4, Cycle 3) were used to test the roles of education, anxiety, anger, sadness, hope, happiness, and an education by anxiety interaction in predicting online health information seeking. Results suggest that women, tablet owners, smartphone owners, the college educated, those who are sad some or all of the time, and those who are anxious most of the time were significantly more likely to seek online health information. Conversely, being angry all of the time decreased the likelihood of seeking. Furthermore, two significant interactions emerged between anxiety and education levels. Discrete psychological states and demographic factors (gender and education) individually and jointly impact information seeking tendencies.

"Prejudiced" behavior without prejudice? Beliefs about the malleability of prejudice affect interracial interactions.

Science.gov (United States)

Carr, Priyanka B; Dweck, Carol S; Pauker, Kristin

2012-09-01

Prejudiced behavior is typically seen as emanating from prejudiced attitudes. Eight studies showed that majority-group members' beliefs about prejudice can create seemingly "prejudiced" behaviors above and beyond prejudice measured explicitly (Study 1b) and implicitly (Study 2). Those who believed prejudice was relatively fixed, rather than malleable, were less interested in interracial interactions (Studies 1a-1d), race- or diversity-related activities (Study 1a), and activities to reduce their prejudice (Study 3). They were also more uncomfortable in interracial, but not same-race, interactions (Study 2). Study 4 manipulated beliefs about prejudice and found that a fixed belief, by heightening concerns about revealing prejudice to oneself and others, depressed interest in interracial interactions. Further, though Whites who were taught a fixed belief were more anxious and unfriendly in an interaction with a Black compared with a White individual, Whites who were taught a malleable belief were not (Study 5). Implications for reducing prejudice and improving intergroup relations are discussed.

Although internalized stigma is associated with negative outcomes among those with prolonged psychosis, surprisingly little work has focused on when in the course of one's illness stigma is internalized and the impact of internalization on symptoms or social functioning over the course of the illness. Therefore, this study investigated whether (1) internalized stigma is greater among those later in the course of psychosis and (2) whether internalized stigma has a stronger negative relationship with social functioning or symptoms among those with prolonged compared to early phase psychosis. Individuals with early phase (n = 40) and prolonged psychosis (n = 71) who were receiving outpatient services at an early-intervention clinic and a VA medical center, respectively, completed self-report measures of internalized stigma and interview-rated measures of symptoms and social functioning. Controlling for education, race and sex differences, internalized stigma was significantly greater among those with prolonged psychosis compared to early phase. Internalized stigma was negatively related to social functioning and positively related to symptoms in both groups. Furthermore, the magnitude of the relationship between cognitive symptoms and internalized stigma was significantly greater among those with early phase. Stereotype endorsement, discrimination experiences and social withdrawal also differentially related to symptoms and social functioning across the 2 samples. Findings suggest that internalized stigma is an important variable to incorporate into models of early psychosis. Furthermore, internalized stigma may be a possible treatment target among those with early phase psychosis. © 2018 John Wiley & Sons Australia, Ltd.

Appropriate animal models of posttraumatic stress disorder (PTSD) are needed because human studies remain limited in their ability to probe the underlying neurobiology of PTSD. Although the single prolonged stress (SPS) model is an established rat model of PTSD, the development of a similarly-validated mouse model emphasizes the benefits and cross-species utility of rodent PTSD models and offers unique methodological advantages to that of the rat. Therefore, the aims of this study were to develop and describe a SPS model for mice and to provide data that support current mechanisms relevant to PTSD. The mouse single prolonged stress (mSPS) paradigm, involves exposing C57Bl/6 mice to a series of severe, multimodal stressors, including 2h restraint, 10 min group forced swim, exposure to soiled rat bedding scent, and exposure to ether until unconsciousness. Following a 7-day undisturbed period, mice were tested for cue-induced fear behavior, effects of paroxetine on cue-induced fear behavior, extinction retention of a previously extinguished fear memory, dexamethasone suppression of corticosterone (CORT) response, dorsal hippocampal glucocorticoid receptor protein and mRNA expression, and prefrontal cortex glutamate levels. Exposure to mSPS enhanced cue-induced fear, which was attenuated by oral paroxetine treatment. mSPS also disrupted extinction retention, enhanced suppression of stress-induced CORT response, increased mRNA expression of dorsal hippocampal glucocorticoid receptors and decreased prefrontal cortex glutamate levels. These data suggest that the mSPS model is a translationally-relevant model for future PTSD research with strong face, construct, and predictive validity. In summary, mSPS models characteristics relevant to PTSD and this severe, multimodal stress modifies fear learning in mice that coincides with changes in the hypothalamo-pituitary-adrenal (HPA) axis, brain glucocorticoid systems, and glutamatergic signaling in the prefrontal cortex

To determine correlation between prolonged QT interval and severity of disease in patients of cirrhosis of liver. Study Design: Descriptive cross sectional study. Patients and Methods: One hundred and seventeen patients of cirrhosis were included. Baseline haematological and biochemical parameters were determined. Model for end stage liver disease (MELD) score was determined for all patients to document stage of liver disease. Corrected QT interval was determined from electrocardiography of each patient using QT cirrhosis formula. Correlation between QT interval and MELD score was determined using Pearson correlation and Receiver Operating Characteristic (ROC) curve. Results: One hundred and seventeen included patients had mean age of 53.58 (+- 12.11) while male to female ratio was 1.78/1 (75 / 42). Mean MELD score was 17.08 (+- 6.54) in study patients varying between 6 and 37 while mean corrected QT interval was 0.44 seconds (+- 0.06). Pearson correlation revealed no significant relation between severity of liver disease as determined with MELD score and prolonged QT interval (p value 0.18) Area under curve with ROC curve for correlation between prolonged QT interval and severity of liver disease was 0.42. Conclusion: Prolonged QT interval is not an indicator of severity of disease in cirrhosis of liver. (author)

Both histologic chorioamnionitis (HCAM) and Ureaplasma infection are considered important contributors to perinatal lung injury. We tested the hypothesis that coexistence of maternal HCAM and perinatal Ureaplasma exposure increases the risk of prolonged mechanical ventilation in extremely low-birthweight (ELBW) infants. A retrospective cohort study was carried out of all ELBW infants born between January 2008 and December 2013 at a single academic center. Placental pathology and gastric fluid Ureaplasma data were available for all infants. Culture and polymerase chain reaction were used to detect Ureaplasma in gastric fluid. Prolonged mechanical ventilation was defined as mechanical ventilation that began within 28 days after birth and continued. Of 111 ELBW infants enrolled, 84 survived beyond 36 weeks of postmenstrual age (PMA) and were included in the analysis. Eighteen infants (21.4%) had both HCAM and Ureaplasma exposure. Seven infants (8.3%) required mechanical ventilation beyond 36 weeks of PMA. Coexistence of HCAM and Ureaplasma in gastric fluid was significantly associated with prolonged mechanical ventilation after adjustment for gestational age, sex, mode of delivery, and use of macrolide antibiotics (OR, 8.7; 95%CI: 1.1-67.2). Coexistence of maternal HCAM and perinatal Ureaplasma exposure significantly increases the risk of prolonged mechanical ventilation in ELBW infants. © 2016 Japan Pediatric Society.

Study objectives: Evaluate the prevalence and phenomenology of dream-associated behaviors affecting pregnant and postpartum mothers. Episodes consist of anxious dreams and nightmares about the new infant that are accompanied by complex behaviors (motor activity, speaking, expressing emotion). Design: Three-group design (postpartum, pregnant, null gravida), self-report, and repeated measures. Setting: Pregnancy and postpartum groups: completion of questionnaires in hospital room within 48 hours of giving birth and home telephone interviews; null gravida group: completion of questionnaires and interview in person or by telephone. Participants: Two hundred seventy-three women in 3 groups: postpartum: n = 202 (mean age = 29.7 ± 4.94 years; 95 primiparas, 107 multiparas); pregnant: n = 50 (mean age = 31.1 ± 5.44 years); null gravida: n = 21 (mean age = 28.5 ± 6.34 years). Interventions: Subjects completed questionnaires about pregnancy and birth factors, personality, and sleep and participated in interviews concerning the prevalence of recent infant dreams and nightmares, associated behaviors, anxiety, depression, and other psychopathologic factors. Measurements and Results: Most women in all groups recalled dreams (88%-91%). Postpartum and pregnant women recalled infant dreams and nightmares with equal prevalence, but more postpartum women reported they contained anxiety (75%) and the infant in peril (73%) than did pregnant women (59%, P dream-associated behaviors (P dream anxiety and, among postpartum women, post-awakening anxiety (41%), confusion (51%), and a need to check on the infant (60%). Primiparas and multiparas differed in dream and nightmare recall but not in prevalence of dream-associated behaviors. Conclusion: The prevalent occurrence of pregnancy and postpartum infant dreams and associated behaviors may reflect the pervasive emotional influence of maternal concerns or changes instigated by severe sleep disruption, rapid eye movement sleep deprivation

A blood transfusion is an acute intervention, used to address life- and health-threatening conditions on a short-term basis. Packed red blood cells are most often used for blood transfusion. Sometimes blood is transfused after prolonged storage but there is continuing debate as to whether transfusion of 'older' blood is as beneficial as transfusion of 'fresher' blood. To assess the clinical benefits and harms of prolonged storage of packed red blood cells, in comparison with fresh, on recipients of blood transfusion. We ran the search on 1st May 2014. We searched the Cochrane Injuries Group Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE (OvidSP), Embase (OvidSP), CINAHL (EBSCO Host) and two other databases. We also searched clinical trials registers and screened reference lists of the retrieved publications and reviews. We updated this search in June 2015 but these results have not yet been incorporated. Randomised clinical trials including participants assessed as requiring red blood cell transfusion were eligible for inclusion. Prolonged storage was defined as red blood cells stored for ≥ 21 days in a blood bank. We did not apply limits regarding the duration of follow-up, or country where the study took place. We excluded trials where patients received a combination of short- and long-stored blood products, and also trials without a clear definition of prolonged storage. We independently performed study selection, risk of bias assessment and data extraction by at least two review authors. The major outcomes were death from any cause, transfusion-related acute lung injury, and adverse events. We estimated relative risk for dichotomous outcomes. We measured statistical heterogeneity using I(2). We used a random-effects model to synthesise the findings. We identified three randomised clinical trials, involving a total of 120 participants, comparing packed red blood cells with ≥ 21 days storage

Full Text Available Prolonged fatigue is common among employees, but the relationship between prolonged fatigue and job-related psychosocial factors is seldom studied. This study aimed (1 to assess the individual relations of physical condition, psychological condition, and job-related psychosocial factors to prolonged fatigue among employees, and (2 to clarify the associations between job-related psychosocial factors and prolonged fatigue using hierarchical regression when demographic characteristics, physical condition, and psychological condition were controlled.A cross-sectional study was employed. A questionnaire was used to obtain information pertaining to demographic characteristics, physical condition (perceived physical health and exercise routine, psychological condition (perceived mental health and psychological distress, job-related psychosocial factors (job demand, job control, and workplace social support, and prolonged fatigue.A total of 3,109 employees were recruited. Using multiple regression with controlled demographic characteristics, psychological condition explained 52.0% of the variance in prolonged fatigue. Physical condition and job-related psychosocial factors had an adjusted R2 of 0.370 and 0.251, respectively. Hierarchical multiple regression revealed that, among job-related psychosocial factors, job demand and job control showed significant associations with fatigue.Our findings highlight the role of job demand and job control, in addition to the role of perceived physical health, perceived mental health, and psychological distress, in workers' prolonged fatigue. However, more research is required to verify the causation among all the variables.

Pair-bonded relationships form during periods of close spatial proximity and high sociosexual contact. Like other monogamous species, marmosets form new social pairs after emigration or ejection from their natal group resulting in periods of social isolation. Thus, pair formation often occurs following a period of social instability and a concomitant elevation in stress physiology. Research is needed to assess the effects that prolonged social isolation has on the behavioral and cortisol response to the formation of a new social pair. We examined the sociosexual behavior and cortisol during the first 90-days of cohabitation in male and female Geoffroy's tufted-ear marmosets (Callithrix geoffroyi) paired either directly from their natal group (Natal-P) or after a prolonged period of social isolation (ISO-P). Social isolation prior to pairing seemed to influence cortisol levels, social contact, and grooming behavior; however, sexual behavior was not affected. Cortisol levels were transiently elevated in all paired marmosets compared to natal-housed marmosets. However, ISO-P marmosets had higher cortisol levels throughout the observed pairing period compared to Natal-P marmoset. This suggests that the social instability of pair formation may lead to a transient increase in hypothalamic-pituitary-adrenal (HPA) axis activity while isolation results in a prolonged HPA axis dysregulation. In addition, female social contact behavior was associated with higher cortisol levels at the onset of pairing; however, this was not observed in males. Thus, isolation-induced social contact with a new social partner may be enhanced by HPA axis activation, or a moderating factor. Published by Elsevier Inc.

In spite of screening procedures in early drug development, uncertainty remains about the propensity of new chemical entities (NCEs) to prolong the QT/QTc interval. The evaluation of proarrhythmic activity using a comprehensive in vitro proarrhythmia assay does not fully account for pharmacokinetic-pharmacodynamic (PKPD) differences in vivo. In the present study, we evaluated the correlation between drug-specific parameters describing QT interval prolongation in dogs and in humans. Using estimates of the drug-specific parameter, data on the slopes of the PKPD relationships of nine compounds with varying QT-prolonging effects (cisapride, sotalol, moxifloxacin, carabersat, GSK945237, SB237376 and GSK618334, and two anonymized NCEs) were analysed. Mean slope estimates varied between -0.98 ms μM -1 and 6.1 ms μM -1 in dogs and -10 ms μM -1 and 90 ms μM -1 in humans, indicating a wide range of effects on the QT interval. Linear regression techniques were then applied to characterize the correlation between the parameter estimates across species. For compounds without a mixed ion channel block, a correlation was observed between the drug-specific parameter in dogs and humans (y = -1.709 + 11.6x; R 2  = 0.989). These results show that per unit concentration, the drug effect on the QT interval in humans is 11.6-fold larger than in dogs. Together with information about the expected therapeutic exposure, the evidence of a correlation between the compound-specific parameter in dogs and in humans represents an opportunity for translating preclinical safety data before progression into the clinic. Whereas further investigation is required to establish the generalizability of our findings, this approach can be used with clinical trial simulations to predict the probability of QT prolongation in humans. © 2016 The British Pharmacological Society.

In breastfeeding newborns who are otherwise healthy, the mechanism of prolonged jaundice remains unclear. The aim of this study was to investigate relations between prolonged jaundice and oxidative parameters in breast milk. Full-term, otherwise healthy newborns with jaundice lasting more than 2 weeks were enrolled prospectively in the study. As a control group, newborns in the same age group but without prolonged jaundice were selected. All newborns in the study were exclusively breastfed. In the newborns with prolonged jaundice, investigations of the etiology of the jaundice included complete blood count, peripheral blood smear, blood typing, direct Coombs test, measurement of serum levels of total and direct bilirubin, tests for liver and thyroid function (TSH, free T4, total T4), urine culture and measurement of urine reducing substances, and determination of glucose 6 phosphate dehydrogenase enzyme levels. Breast milk was collected from the mothers of the newborns in both groups. The antioxidant status of the breast milk was assessed via determination of total antioxidant capacity (TAC). Oxidative stress was also assessed in breast milk by measurement of total oxidation status (TOS) and calculation of the oxidative stress index (OSI). The prolonged jaundice group differed significantly from the control group in terms of mean TAC and OSI (p antioxidant capacity was found to be decreased.

To test the hypothesis that prolonged alkalosis decreases cardiac output and, furthermore, exacerbates hypoxic pulmonary vasoconstriction, as respiratory alkalosis is frequently induced as a therapy for persistent pulmonary hypertension of the newborn despite a lack of controlled evidence of improved outcomes. Potential adverse effects of prolonged alkalosis have been demonstrated. Two groups (control, n = 6, and hypocapnic alkalosis, n = 6) of 1-3 day old fentanyl-anesthetized, vecuronium-paralyzed piglets were instrumented to measure cardiac index (CI) and mean systemic (MAP) and pulmonary (PAP) arterial pressures. Baseline values were recorded. Alveolar hypoxia was then induced to achieve an arterial oxygen saturation of between 50 and 60% for 15 min. Respiratory alkalosis was then induced, by increasing ventilation to achieve a pH between 7.55-7.60, and was continued for 240 min. Inspired carbon dioxide was used with hyperventilation in the control group to maintain pressure of arterial carbon dioxide (PaCO2) at 35-45 mmHg and pH of 7.35-7.45. Hypoxia was induced again at 15 and 240 min. Pulmonary and systemic vascular resistances (PVR and SVR) were calculated. Prolonged alkalosis led to a significant and progressive fall in mean MAP from 61 (SD 7) mmHg at the start of the study falling to 50 (SD 6.9, p = 0.043), with no effect on CI. Calculated SVR decreased (0.45 SD 0.03 vs 0.36 SD 0.05). There were no statistically significant changes in any of the variables in the control group. Neither acute nor prolonged respiratory alkalosis had a significant effect on hypoxic pulmonary vasoconstriction. Prolonged hyperventilation leads to systemic hypotension, however it does not exacerbate hypoxic pulmonary vasoconstriction.

Weaning from prolonged mechanical ventilation may be associated with mental discomfort. It is not known whether such discomfort is linked with the development of post-traumatic stress disorder (PTSD). Accordingly, we investigated whether PTSD occurs in patients after weaning from prolonged ventilation. We also determined whether administering a questionnaire would identify patients at risk for developing PTSD. A prospective longitudinal study of patients transferred to a long-term acute-care hospital for weaning from prolonged ventilation was undertaken: 72 patients were studied 1 week after weaning, and 41 patients were studied again 3 months later. An experienced psychologist conducted a structured clinical interview 3 months after weaning to establish a diagnosis of PTSD. To assess for the presence of PTSD-related symptoms, the post-traumatic stress syndrome (PTSS-10) questionnaire was administered 1 week after weaning and 3 months later. The psychologist diagnosed PTSD in 12% of patients 3 months after ventilator weaning. Patients who developed PTSD were more likely to have a previous history of psychiatric disorders (P 20 one week after weaning reliably identified patients who were diagnosed with PTSD 3 months later: sensitivity 1.0; specificity 0.76; area under the receiver-operating characteristic curve 0.91. PTSD was diagnosed in 12% of patients who were weaned from prolonged ventilation. A PTSS-10 score >20 one week after weaning identified patients diagnosed with PTSD 3 months later. This finding suggests that a simple questionnaire administered before hospital discharge can identify patients at risk for developing PTSD.

Non-contact anterior cruciate ligament (ACL) injuries in athletes occur more often towards the end of athletic competitions. However, the exact mechanisms of how prolonged activity increases the risk for ACL injuries are not clear. To determine the effect of prolonged activity on the hip and knee kinematics observed during self-selected cutting maneuvers performed in a timed agility test. Nineteen female Division I collegiate soccer players completed a self-selected cutting agility test until they were unable to meet a set performance time (one standard deviation of the average baseline trial). Using the 3D dimensional coordinate data the cut type was identified by the principle investigators. The 3D hip and knee angles at 32ms post heel strike were analyzed using a two-factor, linear mixed model to assess the effect of prolonged activity and cut type on the recorded mean hip and knee angles. Athletes performed either sidestep or crossover cuts. An effect of cut type and prolonged activity was seen at the hip and knee. During the prolonged activity trials, the knee was relatively more adducted and both the hip and knee were less flexed than during the baseline trials regardless of cut type. Regardless of activity status, during sidestep cuts, the hip was more internally rotated and abducted, and less flexed than during crossover cuts while the knee was more abducted and less flexed during the sidestep than crossover cuts. During a sport-like agility test, prolonged activity appears to predispose the athlete to position their knee in a more extended and abducted posture and their hip in a more extended posture. This position has been suggested to place stress on the ACL and potentially increase the risk for injury. Clinicians may want to consider the effects of prolonged activity on biomechanical risk factors for sustaining ACL injuries in the design of intervention strategies to prevent ACL injuries. Level 4.

“Prejudiced” Behavior Without Prejudice? Beliefs About the Malleability of Prejudice Affect Interracial Interactions

Science.gov (United States)

Carr, Priyanka B.; Dweck, Carol S.; Pauker, Kristin

2013-01-01

Prejudiced behavior is typically seen as emanating from prejudiced attitudes. Eight studies showed that majority-group members’ beliefs about prejudice can create seemingly “prejudiced” behaviors above and beyond prejudice measured explicitly (Study 1b) and implicitly (Study 2). Those who believed prejudice was relatively fixed, rather than malleable, were less interested in interracial interactions (Studies 1a–d), race- or diversity-related activities (Study 1a), and activities to reduce their prejudice (Study 3). They were also more uncomfortable in interracial, but not same-race, interactions (Study 2). Study 4 manipulated beliefs about prejudice and found that a fixed belief, by heightening concerns about revealing prejudice to oneself and others, depressed interest in interracial interactions. Further, though those taught a fixed belief were more anxious and unfriendly in an interaction with a Black compared to White individual, those taught a malleable belief were not (Study 5). Implications for reducing prejudice and improving intergroup relations are discussed. PMID:22708626

The purpose of this study is to determine the rate of prolonged empiric antibiotic therapy in adult ICUs in the United States. Our secondary objective is to examine the relationship between the prolonged empiric antibiotic therapy rate and certain ICU characteristics. Multicenter, prospective, observational, 72-hour snapshot study. Sixty-seven ICUs from 32 hospitals in the United States. Nine hundred ninety-eight patients admitted to the ICU between midnight on June 20, 2011, and June 21, 2011, were included in the study. None. Antibiotic orders were categorized as prophylactic, definitive, empiric, or prolonged empiric antibiotic therapy. Prolonged empiric antibiotic therapy was defined as empiric antibiotics that continued for at least 72 hours in the absence of adjudicated infection. Standard definitions from the Centers for Disease Control and Prevention were used to determine infection. Prolonged empiric antibiotic therapy rate was determined as the ratio of the total number of empiric antibiotics continued for at least 72 hours divided by the total number of empiric antibiotics. Univariate analysis of factors associated with the ICU prolonged empiric antibiotic therapy rate was conducted using Student t test. A total of 660 unique antibiotics were prescribed as empiric therapy to 364 patients. Of the empiric antibiotics, 333 of 660 (50%) were continued for at least 72 hours in instances where Centers for Disease Control and Prevention infection criteria were not met. Suspected pneumonia accounted for approximately 60% of empiric antibiotic use. The most frequently prescribed empiric antibiotics were vancomycin and piperacillin/tazobactam. ICUs that utilized invasive techniques for the diagnosis of ventilator-associated pneumonia had lower rates of prolonged empiric antibiotic therapy than those that did not, 45.1% versus 59.5% (p = 0.03). No other institutional factor was significantly associated with prolonged empiric antibiotic therapy rate. Half of all

The patients in the real stimulation group underwent 20 anodal tDCS sessions of the left dorsolateral prefrontal cortex (DLPFC over 10 consecutive working days. The CRS-R score and P300 amplitude and latency in a hierarchical cognitive assessment were recorded to evaluate the consciousness level before tDCS and immediately after the 20 sessions.ResultsThe intra-group CRS-R analysis revealed a clinically significant improvement in the MCS patients in the real stimulation group. The inter-group CRS-R analysis showed a significant difference in CRS-R between VS and MCS patients at baseline in both the real and sham stimulation groups. The intra-group ERP analysis revealed a significant increase in P300 amplitude after tDCS in the MCS patients in the real stimulation group, but no significant differences in P300 latency. For the inter-group ERP analysis, we observed significant differences regarding the presence of P300 at baseline between the VS and MCS patients in both groups.ConclusionThe repeated anodal tDCS of the left DLPFC could produce clinically significant improvements in MCS patients. The observed tDCS-related consciousness improvements might be related to improvements in attention resource allocation (reflected by the P300 amplitude. The findings support the use of tDCS in

Daxing Gu

2017-06-01

Full Text Available In arid and semiarid lands, canopy transpiration and its dynamics depend largely on stomatal sensitivity to drought. In this study, the sap flow of a dominant species, Haloxylon ammodendron growing in Central Asian deserts, was monitored using Granier-type sensors, from which the canopy stomatal conductance was derived. The responses of canopy transpiration and stomatal conductance to environmental variables during the second half of the growing season, when annual prolonged drought occurred, was analyzed for four continuous years, from 2013 to 2016. A soil water content (SWC of 3% was identified as the lower soil water threshold for this species, below which the plant lost the ability for stomatal regulation on water loss and suffered the risk of mortality. Above this threshold, the sensitivity of canopy transpiration to vapor pressure deficit, VPD (K, was linearly correlated with SWC, which mainly resulted from different stomatal behaviors at varying drought intensities. Stomatal sensitivity to VPD (m/Gsref increased linearly with soil moisture deficit, inducing a shift from more anisohydric to a more isohydric stomatal behavior. The flexibility of stomatal behavior regarding soil drought was one key element facilitating the survival of H. ammodendron in such an extreme dry environment.

Full Text Available Background: Jaundice is a common condition among neonates. Prolonged unconjugated hyperbilirubinemia occurs when jaundice persists beyond two weeks in term neonates and three weeks in preterm neonates. This study aimed to determine the etiologies of prolonged unconjugated hyperbilirubinemia in infants admitted to the neonatal ward of Besat Hospital in Hamadan, Iran. Methods: This study was conducted on all infants diagnosed with prolonged unconjugated hyperbilirubinemia during 2007-2012 in the neonatal ward of Besat Hospital in Hamadan, Iran. Demographic characteristics of infants, physical examination and laboratory findings were collected and analyzed to determine the etiologies of neonatal hyperbilirubinemia. Results: In total, 100 infants diagnosed with neonatal hyperbilirubinemia were enrolled in this study, including 49 male and 51 female neonates with mean age of 20±1 days and mean bilirubin level of 17.5±4.0 mg/dL. Main causes of hyperbilirubinemia were urinary tract infection, ABO incompatibility, hypothyroidism and glucose-6-phosphate dehydrogenase deficiency in 14%, 5%, 6% and 5% of neonates, respectively. Moreover, unknown etiologies, such as breastfeeding, were detected in 70% of the studied infants. Conclusion: According to the results of this study, determining the main causes of prolonged unconjugated hyperbilirubinemia in neonates is of paramount importance. In the majority of cases, neonatal hyperbilirubinemia is associated with physiological factors, such as breastfeeding.

Full Text Available Mounting evidence indicates that in chronic inflammatory arthritis (CIA, QTc prolongation is frequent and correlates with systemic inflammatory activation. Notably, basic studies demonstrated that inflammatory cytokines induce profound changes in potassium and calcium channels resulting in a prolonging effect on cardiomyocyte action potential duration (APD, thus on the QT interval on the electrocardiogram. Moreover, it has been demonstrated that in RA patients the risk of SCD is significantly increased when compared to non-RA subjects. Conversely, to date no data are available about Torsades de Pointes (TdP prevalence in CIA, and the few case reported considered CIA only an incidental concomitant disease, not contributing factor to TdP development.We report three patients with active CIA developing marked QTc prolongation, in two cases complicated with TdP degenerating to cardiac arrest. In these patients, a blood sample was obtained within 24h from TdP/marked QTc prolongation occurrence and levels of IL-6, TNF-alpha and IL-1 were evaluated. In all three cases, IL-6 was markedly elevated, ~10 to 100 times more than reference values. Moreover, one patient also showed high circulating levels of TNF-alpha and IL-1. In conclusion, active CIA may represent a currently overlooked QT-prolonging risk factor, potentially contributing in the presence of other classical risk factors to TdP occurrence. In particular, a relevant role may be played by elevated circulating IL-6 levels via direct electrophysiological effects on the heart. This observation should be carefully kept in mind, particularly when recognizable risk factors are already present and/or the addition of QT-prolonging drugs is required.

Controlling parenting is associated with child anxiety however the direction of effects remains unclear. The present study implemented a Latin-square experimental design to assess the impact of parental control on children's anxious affect, cognitions and behaviour. A non-clinical sample of 24 mothers of children aged 4-5 years were trained to engage in (a) controlling and (b) autonomy-granting behaviours in interaction with their child during the preparation of a speech. When mothers engaged in controlling parenting behaviours, children made more negative predictions about their performance prior to delivering their speech and reported feeling less happy about the task, and this was moderated by child trait anxiety. In addition, children with higher trait anxiety displayed a significant increase in observed child anxiety in the controlling condition. The pattern of results was maintained when differences in mothers' levels of negativity and habitual levels of control were accounted for. These findings are consistent with theories that suggest that controlling parenting is a risk factor in the development of childhood anxiety. Copyright 2010 Elsevier Ltd. All rights reserved.

The present study provides a comprehensive view of (a) the time dynamics of the psychophysiological responding in performing music students (n = 66) before, during, and after a private and a public performance and (b) the moderating effect of music performance anxiety (MPA). Heart rate (HR), minute ventilation (VE), and all affective and somatic self-report variables increased in the public session compared to the private session. Furthermore, the activation of all variables was stronger during the performances than before or after. Differences between phases were larger in the public than in the private session for HR, VE, total breath duration, anxiety, and trembling. Furthermore, while higher MPA scores were associated with higher scores and with larger changes between sessions and phases for self-reports, this association was less coherent for physiological variables. Finally, self-reported intra-individual performance improvements or deteriorations were not associated with MPA. This study makes a novel contribution by showing how the presence of an audience influences low- and high-anxious musicians' psychophysiological responding before, during and after performing. Overall, the findings are more consistent with models of anxiety that emphasize the importance of cognitive rather than physiological factors in MPA.

The aim of the present study was to question untested assumptions about the nature of the expression of Attentional Bias (AB) towards and away from threat stimuli. We tested the idea that high trait anxious individuals (N = 106; M(SD)age = 23.9(3.2) years; 68% women) show a stable AB towards multiple categories of threatening information using the emotional visual dot probe task. AB with respect to five categories of threat stimuli (i.e., angry faces, attacking dogs, attacking snakes, pointed weapons, violent scenes) was evaluated. In contrast with current theories, we found that 34% of participants expressed AB towards threat stimuli, 20.8% AB away from threat stimuli, and 34% AB towards some categories of threat stimuli and away from others. The multiple observed expressions of AB were not an artifact of a specific criterion AB score cut-off; not specific to certain categories of threat stimuli; not an artifact of differences in within-subject variability in reaction time; nor accounted for by individual differences in anxiety-related variables. Findings are conceptualized as reflecting the understudied dynamics of AB expression, with implications for AB measurement and quantification, etiology, relations, and intervention research.

The duration of untreated psychosis (DUP) has been shown to have an effect on outcome after first-episode psychosis. The premise of specialized early intervention (SEI) services is that intervention in the early years of illness can affect long-term outcomes. In this study, we investigate whether DUP affects treatment response after 5 years of SEI treatment compared to 2 years of SEI treatment. As part of a randomized controlled trial testing the effect of prolonged SEI treatment 400 participants diagnosed within the schizophrenia spectrum were recruited. For this specific study participants were dichotomized based on DUP, treatment delay, and time from first symptom until start of SEI treatment. The groups were analyzed with regard to treatment response on psychopathology, level of functioning, and cognitive functioning. The participants with a short DUP had a tendency to respond better to the prolonged treatment with regards to disorganized and negative dimension. For participants with short duration from first symptom until start of SEI treatment there was a significant difference on the negative dimension favoring the prolonged OPUS treatment. The finding of an effect of prolonged treatment for participants with a short total treatment delay could mean that prolonged SEI treatment is more beneficial than treatment as usual (TAU) so long as it is provided in the early years of illness and not just in the early years after diagnosis. THE EARLIER THE BETTER: The duration of untreated psychosis influences the long-term outcomes of treatment. Nikolai Albert, at the Copenhagen Mental Health Centre, and a team of Danish researchers have investigated the effects of a specialized early intervention program (OPUS) in 400 patients diagnosed with schizophrenia spectrum disorders and compared the effects of OPUS after two and five years. Their findings suggest that five years of specialized early intervention was most beneficial when the total duration from symptom start to

Cardiac toxicity is the foremost reason for drug discontinuation from development to clinical evaluation and post market surveillance [Fung 35:293-317, 2001; Piccini 158:317-326 2009]. The Food and Drug Administration (FDA) has rejected many potential pharmaceutical agents due to QT prolongation effects. Since drug development and FDA approval takes an enormous amount of time, money and effort with high failure rates, there is an increased focus on rescuing drugs that cause QT prolongation. If these otherwise safe and potent drugs were formulated in a unique way so as to mitigate the QT prolongation associated with them, these potent drugs may get FDA approval for clinical use. Rescuing these compounds not only benefit the patients who need them but also require much less time and money thus leading to faster clinical translation. In this study, we chose curcumin as our drug of choice since it has been shown to posses anti-tumor properties against various cancers with limited toxicity. The major limitations with this pharmacologically active drug are (a) its ability to prolong QT by inhibiting the hERG channel and (b) its low bioavailability. In our previous studies, we found that lipids have protective actions against hERG channel inhibition and therefore QT prolongation. Results of the manual patch clamp assay of HEK 293 cells clearly illustrated that our hybrid nanocurcumin formulation prevented the curcumin induced inhibition of hERG K+ channel at concentrations higher than the therapeutic concentrations of curcumin. Comparing the percent inhibition, the hybrid nanocurcumin limited inhibition to 24.8% at a high curcumin equivalent concentration of 18 μM. Liposomal curcumin could only decrease this inhibition upto 30% only at lower curcumin concentration of 6 μM but not at 18 μM concentration. Here we show a curcumin encapsulated lipopolymeric hybrid nanoparticle formulation which could protect against QT prolongation and also render increased

To assess the possibility that acute caffeine's behavioral action might depend on rats' strain, effects of 50mg/kg of the drug were observed on activity, anxiety-related behavior and habituation learning in male and female rats from three different strains, namely PVG/c, Long-Evans and Wistar. All subjects were tested in an open field, an elevated plus maze and a light-dark box. For the three strains combined, increased occupancy of the center of the open field and entries of the open plus-maze arms with caffeine suggested caffeine-induced anxiolysis, whereas increased grooming in the open field, decreased rearing in the plus maze and increased risk assessment in the light-dark box were consistent with anxiogenesis. Caffeine also reduced open-field rearing only for PVG/c rats, and entries into and occupation of the light side of the light-dark box only for Long-Evans rats, and increased total defecation in the three types of apparatus for all three strains combined. Overall, caffeine appeared to be mainly anxiogenic. The drug also increased open-field ambulation for PVG/c rats and walking for all rats, but decreased open-field ambulation and entries into the plus maze closed arms for Wistar rats alone. In general, Wistar rats appeared to be the least and Long-Evans the most anxious of the three strains investigated. Caffeine also decreased within-session habituation of open-field ambulation for PVG/c rats alone, thereby suggesting strain-dependent interference with non-associative learning and short-term memory. Several overall sex differences were also observed that supported female rats being more active and less anxious than males. Copyright © 2015 Elsevier Inc. All rights reserved.

Prolonged minor allograft survival in intravenously primed mice--a test of the veto hypothesis

Johnson, L.L.

1987-01-01

Experiments were performed to test the hypothesis that veto cells are responsible for the prolonged survival of minor allografts of skin that is observed in recipients primed intravenously with spleen cells from mice syngeneic with the skin donors. This prolonged survival was observed for each of several minor histocompatibility (H) antigens and is antigen-specific. Gamma radiation (3300 rads) abolished the ability of male spleen cells infused i.v. to delay the rejection of male skin grafts (H-Y antigen) on female recipients. However, depletion of Thy-1+ cells from the i.v. infusion failed to abolish the ability to prolong male skin graft survival. Furthermore, the prolonged survival accorded to B6 (H-2b) male skin grafts on CB6F1 (H-2b/H-2d) female recipients given i.v. infusions of B6 male spleen cells extended to BALB/c (H-2d) male skin grafts as well, indicating a lack of MHC restriction. Thus, prolongation of minor allograft survival by i.v. infusion of minor H antigen-bearing spleen cells appears not to depend on veto T cells that others have found to be responsible for the suppression of CTL generation

The radioprotective agent WR-2721 was linked to dextran and poly(glutamic acid) respectively, to obtain a prolonged radioprotective ability. Male mice were administered these water soluble polymer conjugates one to 72 hours prior to a whole body irradiation with X-rays. A prolongation of radioprotective efficiency was achieved with two dextran-(WR-2721)-conjugates. For a period of 24 hours between administration, and irradiation dose reduction factors of 1.14±0.04 and 1.10±0.03 respectively were found. After 72 hours, no protective effect was observed. Histopathological investigations of the liver for formation of tumors 200 to 600 days after irradiation seems to indicate that a protective effect is not produced by the dextran-(WR-2721)-conjugats.

The objective of this paper is to describe the mental health and service utilization of graduate students at a large southeastern university and identify psychological factors associated with their student suicidal behavior. E-mail invitations to complete the Interactive Screening Program, an online anonymous mental health questionnaire, were sent to graduate students. The questionnaire included the Patient Health Questionnaire (PHQ-9) as well as items assessing suicide behavior, anxiety, negative emotion, substance use, eating behavior, and service utilization. A total of 301 graduate students responded to the questionnaires between 14 July 2010 and 24 January 2012. With regards to suicide, 7.3 % of the sample reported thoughts of suicide, 2.3 % reported having plans for suicide, and 1.7 % had hurt themselves in the past 2 weeks; while 9.9 % had ever made a suicide attempt in their lifetime. Graduate students had PHQ-9 scores indicating mild depression, and more than half endorsed feeling nervous, irritable, stressed, anxious, lonely, or having fights/arguments. In terms of service utilization, 22.2 % of the sample was currently taking some type of medication, and 18.5 % currently in counseling/therapy are females and those with higher PHQ-9 scores more likely to be using services. Those endorsing suicidal behavior in the past 2 weeks had significantly higher depression scores than those without such behavior and were characterized by more anxiety, negative emotions (such as loneliness, anger, hopelessness, desperation, and being out of control), substance use, and eating problems. Graduate students experience significant amounts of stress and anxiety, and their suicidal behavior is strongly characterized by depression, hopelessness, desperation, lack of control, and eating problems. Future work with this population should focus on the development and evaluation of mental health and wellness interventions and on ways to promote help-seeking, especially among male

The average time spent playing video games is increasing. Prolonged immobility associated with gaming may therefore be an important risk factor for venous thromboembolism. We report a case of deep vein thrombosis associated with prolonged playing of PlayStation® games. A 31-year-old Caucasian man, an exterior painter, presented with a three-day history of left leg pain and swelling after playing PlayStation® games for almost eight hours a day for four consecutive days. Doppler ultrasound of the left leg confirmed extensive left leg deep venous thrombosis requiring thrombolysis and anticoagulation. Video gaming should be considered a risk factor for venous thromboembolism. Further studies are needed to estimate the degree of risk associated with prolonged periods of playing video games, and education for preventing venous thrombosis should be provided to gamers.

The purpose is to investigate whether a change in putative mediators (negative and positive thoughts, coping strategies, and perceived control over anxious situations) precedes a change in anxiety symptoms in anxiety-disordered children and adolescents receiving cognitive behavioral therapy (CBT). Participants were 145 Dutch children (8-18 years old, M = 12.5 years, 57% girls) with a primary anxiety disorder. Assessments were completed pretreatment, in-treatment, posttreatment, and at 3-month follow-up. Sequential temporal dependencies between putative mediators and parent- and child-reported anxiety symptoms were investigated in AMOS using longitudinal Latent Difference Score Modeling. During treatment an increase of positive thoughts preceded a decrease in child-reported anxiety symptoms. An increase in three coping strategies (direct problem solving, positive cognitive restructuring, and seeking distraction) preceded a decrease in parent-reported anxiety symptoms. A reciprocal effect was found for perceived control: A decrease in parent-reported anxiety symptoms both preceded and followed an increase in perceived control. Using a longitudinal design, a temporal relationship between several putative mediators and CBT-outcome for anxious children was explored. The results suggest that a change in positive thoughts, but not negative thoughts, and several coping strategies precedes a change in symptom reduction and, therefore, at least partly support theoretical models of anxiety upon which the anxiety intervention is based.

The American alligator (Alligator mississippiensis) is a semi-aquatic diving reptile that has a periodic breathing pattern. Previous work identified pulmonary stretch receptors, that are rapidly and slowly adapting, as well as intrapulmonary chemoreceptors (IPC), sensitive to CO2, that modulate breathing patterns in alligators. The purpose of the present study was to quantify the effects of prolonged lung inflation and deflation (simulated dives) on pulmonary stretch receptors (PSR) and/or IPC discharge characteristics. The effects of airway pressure (0-20 cm H2O), hypercapnia (7% CO2), and hypoxia (5% O2) on dynamic and static responses of PSR were studied in juvenile alligators (mean mass=246 g) at 24°C. Alligators were initially anesthetized with isoflurane, cranially pithed, tracheotomized and artificially ventilated. Vagal afferent tonic and phasic activity was recorded with platinum hook electrodes. Receptor activity was a mixture of slowly adapting PSR (SAR) and rapidly adapting PSR (RAR) with varying thresholds and degrees of adaptation, without CO2 sensitivity. Receptor activity before, during and after 1 min periods of lung inflation and deflation was quantified to examine the effect of simulated breath-hold dives. Some PSR showed a change in dynamic response, exhibiting inhibition for several breaths after prolonged lung inflation. Following 1 min deflation, RAR, but not SAR, exhibited a significant potentiation of burst frequency relative to control. For SAR, the post-inflation receptor inhibition was blocked by CO2 and hypoxia; for RAR, the post-inflation inhibition was potentiated by CO2 and blocked by hypoxia. These results suggest that changes in PSR firing following prolonged inflation and deflation may promote post-dive ventilation in alligators. We hypothesize that PSR in alligators may be involved in recovery of breathing patterns and lung volume during pre- and post-diving behavior and apneic periods in diving reptiles. Copyright © 2014

While many studies have investigated the effects of transmitters on fish condition, behavior, and survival, to our knowledge, no studies have taken into account anesthetic exposure time in addition to tag and surgery effects. We investigated stress responses to prolonged MS-222 exposure after stage 4 induction in surgically implanted juvenile Chinook salmon (Oncorhynchus tshawytscha). Survival, tag loss, plasma cortisol concentration, and blood Na⁺, K⁺, Ca²⁺, and pH were measured immediately following anesthetic exposure and surgical implantation and 1, 7, and 14 days post-treatment. Despite the prolonged anesthetic exposure, 3-15 minutes post Stage 4 induction, there were no mortalities or tag loss in any treatment. MS-222 was effective at delaying immediate cortisol release during surgical implantation; however, osmotic disturbances resulted, which were more pronounced in longer anesthetic time exposures. From day 1 to day 14, Na⁺, Ca²⁺, and pH significantly decreased, while cortisol significantly increased. The cortisol increase was exacerbated by surgical implantation. There was a significant interaction between MS-222 time exposure and observation day for Na⁺, Ca²⁺, K⁺, and pH; variations were seen in the longer time exposures, although not consistently. In conclusion, stress response patterns suggest stress associated with surgical implantation is amplified with increased exposure to MS-222.

Hydroelectrolytic and hormonal modifications related to prolonged bedrest in antiorthostatic position

Science.gov (United States)

Güell, A.; Dupui, Ph.; Fanjaud, G.; Bes, A.; Moatti, J. P.; Gharrib, Cl.

The effects of prolonged bedrest in antiorthostatic position (-4° head down) on electrolyte balance were studied in 4 young volunteers. An increase was noted in sodium excretion during the first 4 days. Plasma renin activity and plasma aldosterone varied in parallel manner during the same period. Potassium balance and creatinine clearance were not significantly modified. In light of these data we feel that prolonged bedrest in antiorthostatic position constitutes an effective way to simulate on earth metabolic and hormonal modifications occurring in man under weightlessness conditions.

Background The aim of the present work was to characterize the electrophysiological effects of the non-steroidal anti-inflammatory drug diclofenac and to study the possible proarrhythmic potency of the drug in ventricular muscle. Methods Ion currents were recorded using voltage clamp technique in canine single ventricular cells and action potentials were obtained from canine ventricular preparations using microelectrodes. The proarrhythmic potency of the drug was investigated in an anaesthetized rabbit proarrhythmia model. Results Action potentials were slightly lengthened in ventricular muscle but were shortened in Purkinje fibers by diclofenac (20 µM). The maximum upstroke velocity was decreased in both preparations. Larger repolarization prolongation was observed when repolarization reserve was impaired by previous BaCl2 application. Diclofenac (3 mg/kg) did not prolong while dofetilide (25 µg/kg) significantly lengthened the QTc interval in anaesthetized rabbits. The addition of diclofenac following reduction of repolarization reserve by dofetilide further prolonged QTc. Diclofenac alone did not induce Torsades de Pointes ventricular tachycardia (TdP) while TdP incidence following dofetilide was 20%. However, the combination of diclofenac and dofetilide significantly increased TdP incidence (62%). In single ventricular cells diclofenac (30 µM) decreased the amplitude of rapid (IKr) and slow (IKs) delayed rectifier currents thereby attenuating repolarization reserve. L-type calcium current (ICa) was slightly diminished, but the transient outward (Ito) and inward rectifier (IK1) potassium currents were not influenced. Conclusions Diclofenac at therapeutic concentrations and even at high dose does not prolong repolarization markedly and does not increase the risk of arrhythmia in normal heart. However, high dose diclofenac treatment may lengthen repolarization and enhance proarrhythmic risk in hearts with reduced repolarization reserve. PMID:23300901

A considerable amount of evidence exists in support of the role of ultraviolet radiation as a major etiologic factor in human skin cancer, both melanoma and carcinoma types. On the basis of epidemiologic studies a phenotype has been described which helps to identify the persons who are more susceptible to skin cancer. In an attempt to further define this population, patients with cutaneous carcinoma and a normal control group were exposed to artificial ultraviolet light (UVL) and the erythema and tanning responses of each group were measured over a 21-day period. UVL-induced erythema was prolonged in a significantly higher percentage of patients with skin cancer than in control patients, lasting two to three weeks after single exposures to 6 and 8 times the patient's minimal erythema dose. The presence of prolonged erythema correlated with this history of previous skin cancer but did not correlate with other established risk factors for cutaneous carcinoma, i.e., fair skin, light hair and light eyes, easy sunburning and poor tanning, and Celtic ancestry. Prolonged erythema following UVL radiation may therefore represent an additional risk factor and help to identify the skin cancer-susceptible population

Cognitive-behavioral therapy (CBT) and pharmacotherapy are the most well-established treatments for childhood anxiety disorders. This study examined how parents (N=71) seeking treatment for their child's anxiety disorder perceive the acceptability, believability, and effectiveness of these treatments. While both treatments were perceived favorably, CBT was rated as more acceptable, believable, and effective in the short- and long-term. Children's treatment history influenced parents' perceptions of pharmacotherapy, with parents of children with no treatment history perceiving medication treatment as less acceptable and believable than parents of children with a history of medication alone or in combination with behavior therapy. No effect of treatment history was found for perceptions of CBT. Significant positive correlations emerged between parents' perceived acceptance and believability for pharmacotherapy and child age and level of dysfunction due to their child's anxiety, respectively. The level of the child's anxiety was not significantly correlated with parents' perceptions of either CBT or pharmacotherapy. Our results suggest that parents of anxious children prefer CBT to medication for the treatment of their child's anxiety disorder. Directions for future research are discussed.
