    Despite robust investigations examining the impact of maternal anxiety and parenting behaviors and child anxiety risk, less is understood about the impact of paternal anxiety and parenting behaviors on child anxiety risk, particularly within the broader family context. An Actor Partner Interdependence Model (APIM) was used to examine whether paternal anxiety longitudinally predicted child anxiety risk indirectly through maternal and paternal parenting behaviors, while controlling for maternal anxiety. Both fathers and mothers of 12- to 30-month-olds (n = 94) provided self-report of their anxiety and parenting behaviors. Child inhibited temperament (i.e., anxiety risk) was coded. Two APIMs separately considering encouragement of independence and overprotection were examined. These models revealed no direct relation between parent and child anxiety while controlling for parenting behaviors. Models did suggest that paternal anxiety is indirectly linked with future child anxiety through lower maternal encouragement of independence, but not through maternal overprotection or paternal parenting behaviors.

    Intrusive parenting, primarily examined among middle to upper-middle class mothers, has been positively associated with the presence and severity of anxiety in children. This study employed cross-sectional linear regression and longitudinal latent growth curve analyses to evaluate the main and interactive effects of early childhood paternal autonomy restriction (AR) and neighborhood safety (NS) on the trajectory of child anxiety in a sample of 596 community children and fathers from the NICHD SECYD. Longitudinal analyses revealed that greater paternal AR at age 6 was actually associated with greater decreases in child anxiety in later childhood. Cross-sectional analyses revealed main effects for NS across childhood, and interactive effects of paternal AR and NS that were present only in early childhood, whereby children living in safer neighborhoods demonstrated increased anxiety when experiencing lower levels of paternal AR. Findings further clarify for whom and when paternal AR impacts child anxiety in community youth. PMID:25242837

    Exposure to parental depression and anxiety is known to heighten the risk of internalizing symptoms and disorders in children and adolescents. Ample research has focused on the influence of maternal depression and anxiety, but the contribution of psychopathology in fathers remains unclear. We studied the relationships of perceived maternal and paternal psychopathology with adolescents’ depression and anxiety symptoms in a general population sample of 862 adolescent girls (age M = 12.39, SD = 0.79). Assessments included adolescents’ self-reports of their own depression and anxiety as well as their reports of maternal and paternal psychopathology. We found that perceived maternal and paternal psychopathology were both related to depression and anxiety symptoms in adolescent girls. A combination of higher maternal and paternal psychopathology was related to even higher levels of depression and anxiety in adolescent girls. Our findings showed that adolescents’ perceptions of their parents’ psychopathology are significantly related to their own emotional problems. PMID:26257664

    Full Text Available Bisphenol A (BPA, an environmental endocrine-disrupting compound, has drawn a great attention for its adverse effect on behavioral development. Maternal exposure to this compound has been reported to induce anxiety and depression in offspring, but the effect of its paternal exposure is rarely discussed. This study investigated whether preconception paternal BPA exposure can affect the emotions of male rats and their offspring. Eighteen adult male rats (F0 received either a vehicle or 50 μg/kg/day BPA diet for 21 weeks and were then mated with non-exposed females to produce offspring (F1. The affective behaviors of F0 and F1 rats were evaluated in the open-field test, the elevated-plus maze and the forced swimming test, and their serum corticosterone were then examined. BPA exposure induced increased anxiety behaviors along with increased serum corticosterone in F0 rats. This paternal exposure also led to increased anxiety behaviors in F1 females and aggravated depression behaviors in both sexes of F1 rats. Furthermore, only F1 females exhibited increased serum corticosterone. Overall, these data indicate that preconception paternal exposure to a low dose of BPA may induce transgenerational sex-specific impairments in the affection of adult rats.

    In this meta-analysis we investigated differential associations between maternal and paternal parenting behaviors (overcontrol, overprotection, overinvolvement, autonomy granting, challenging parenting) and anxiety and its precursors (fearful temperament, behavioral inhibition, shyness) in children (0-5years). Two meta-analyses were conducted, one for mothers (k=28, N=5,728), and one for fathers (k=12, N=1,019). In general, associations between parenting and child anxiety were small. Associations between child anxiety and overcontrol, overprotection, and overinvolvement did not differ for mothers and fathers. Maternal autonomy granting was not significantly related to child anxiety, and no studies examined fathers' autonomy granting. A significant difference was found for challenging parenting; mothers' challenging parenting was not significantly related to child anxiety, whereas fathers' challenging parenting was related to less child anxiety. Post-hoc meta-analyses revealed that mothers' and fathers' parenting was more strongly related to children's anxiety symptoms than to child anxiety precursors. Moreover, the association between parenting and child anxiety symptoms was stronger for fathers than for mothers. In conclusion, although parenting plays only a small role in early childhood anxiety, fathers' parenting is at least as important as mothers'. Paternal challenging behavior even seems more important than maternal challenging behavior. Research is needed to determine whether challenging fathering can prevent child anxiety development.

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

    Early-life stress and biological predispositions are linked to mood and personality disorders related to aggressive behavior. We previously showed that exposure to peripubertal stress leads to increased anxiety-like behaviors and aggression against males and females, as well as increased aggression against females in their male offspring. Here, we investigated whether paternal (pS) and individual (iS) exposure to peripubertal stress may exert additive effects on the long-term programming of anxiety-like and aggressive behaviors in rats. Given the key role of the lateral septum (LS) in the regulation of anxiety and aggressive behaviors and the hypothesized alterations in balance between neural excitation and inhibition in aggression-related disorders, markers for these processes were examined in the LS. Peripubertal stress was applied both in naïve male rats and in the offspring of peripubertally stressed males, and anxiety-like and aggressive behaviors were assessed at adulthood. Proton magnetic resonance spectroscopy at 6-months, and post-mortem analysis of glutamic acid decarboxylase 67 (GAD67) at 12-months were conducted in LS. We confirmed that aggressive behavior was increased by pS and iS, while only iS increased anxiety-like behavior. Individual stress led to reduced GABA, confirmed by reduced GAD67 immunolabelling, and increased glutamate, N-acetyl-aspartate, phosphocholine and creatine; while pS specifically led to reduced phosphocreatine. pS and iS do not interact and exert a differential impact on the analyzed aspects of brain function and anxiety-like behaviors. These data support the view that early-life stress can affect the behavioral and neurodevelopmental trajectories of individuals and their offspring, which may involve different neurobiological mechanisms.

    Previous research has suggested that harsh discipline is still prevalent in modern Chinese families and it is necessary to explore the cause and the potential mechanisms of Chinese parental use of harsh discipline. This study examined the mediating effects of parental anxiety in the relations between child negative emotionality and parental harsh discipline in China. Using a sample of 328 Chinese father-mother dyads with their young children, findings revealed that maternal anxiety mediated the relations between child negative emotionality and maternal psychological aggression and corporal punishment, but the mediating effects of paternal anxiety on the relations between child negative emotionality and paternal harsh discipline was not significant. The findings provide an important supplement and extension to previous examinations of the factors associated with Chinese parental use of harsh discipline and its mechanisms. PMID:28326056

    The present paper aims to longitudinally assess the emotional functioning of children of mothers with depression, anxiety, or eating disorders and of mothers with no psychological disorders and to evaluate the possible mediating role of fathers' psychological profiles on children's internalizing/externalizing functioning using SCID I, SCL-90/R and CBCL/1½-5. The results showed maternal psychopathology to be strongly related to children's maladaptive profiles. Children of mothers with depression and anxiety showed higher internalizing scores than children of other groups. These scores increased from T1 to T2. Children of mothers with eating disorders showed higher and increasing externalizing scores than children of other groups. The data showed that fathers' interpersonal sensitivity, depression, anxiety and psychoticism significantly predicted internalizing problems of the children. Moreover, interpersonal sensitivity and psychoticism significantly predicted externalizing problems. Our results confirmed the impact of maternal psychopathology on maladaptive outcomes in their children, which suggests the importance of considering paternal psychological profiles.

    Full Text Available Background . Attachment behaviors play an important role in accepting the identity of the fathers, the pleasant outcome of pregnancy and the child’s growth and development in the future. Objectives . This study aimed to investigate the effect of father’s attachment training (awaiting a child on paternal-fetal attachment and parental anxiety. Material and methods . This clinical trial was conducted on 150 spouses of eligible pregnant women. In the intervention group, four 90-minute training sessions were designed on maternal-fetal attachment, while the control group received routine prenatal care. The questionnaire of paternal-fetal attachment was completed both before and after intervention in both cases and control groups. Data analysis was done in SPSS software using a paired t-test and independent t-test (the significant level was 0.05. Results . The mean score of attachment was reported as 56.61 ± 6.05 and 64.53 ± 6.94 both before and after intervention, respectively. According to the paired t-test, there was a significant difference in the attachment score after intervention (p < 0.001. According to the independent t-test applied a month after intervention, the comparison of fathers’ anxiety scores before and after intervention showed a significant difference between the control and intervention groups (p < 0.001. Conclusions . Training fathers about attachment skills leads to increased paternal-fetal attachment and a lower anxiety score. Therefore, it seems necessary to include education of fathers in prenatal care.

    As already demonstrated in greenhouse trials, outcrossing of transgenic plants can be drastically reduced via transgene integration into the plastid. We verified this result in the field with Petunia , for which the highest paternal leakage has been observed. The variety white 115 (W115) served as recipient and Pink Wave (PW) and the transplastomic variant PW T16, encoding the uid A reporter gene, as pollen donor. While manual pollination in the greenhouse led to over 90% hybrids for both crossings, the transgenic donor resulted only in 2% hybrids in the field. Nevertheless paternal leakage was detected in one case which proves that paternal inheritance of plastid-located transgenes is possible under artificial conditions. In the greenhouse, paternal leakage occurred in a frequency comparable to published results. As expected natural pollination reduced the hybrid formation in the field from 90 to 7.6% and the transgenic donor did not result in any hybrid.

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

  19. Paternal care decreases foraging activity and body condition, but does not impose survival costs to caring males in a Neotropical arachnid.

    Directory of Open Access Journals (Sweden)

    Gustavo S Requena

    Full Text Available Exclusive paternal care is the rarest form of parental investment in nature and theory predicts that the maintenance of this behavior depends on the balance between costs and benefits to males. Our goal was to assess costs of paternal care in the harvestman Iporangaia pustulosa, for which the benefits of this behavior in terms of egg survival have already been demonstrated. We evaluated energetic costs and mortality risks associated to paternal egg-guarding in the field. We quantified foraging activity of males and estimated how their body condition is influenced by the duration of the caring period. Additionally, we conducted a one-year capture-mark-recapture study and estimated apparent survival probabilities of caring and non-caring males to assess potential survival costs of paternal care. Our results indicate that caring males forage less frequently than non-caring individuals (males and females and that their body condition deteriorates over the course of the caring period. Thus, males willing to guard eggs may provide to females a fitness-enhancing gift of cost-free care of their offspring. Caring males, however, did not show lower survival probabilities when compared to both non-caring males and females. Reduction in mortality risks as a result of remaining stationary, combined with the benefits of improving egg survival, may have played an important and previously unsuspected role favoring the evolution of paternal care. Moreover, males exhibiting paternal care could also provide an honest signal of their quality as offspring defenders, and thus female preference for caring males could be responsible for maintaining the trait.

    The objective of this study was to examine medical illness and anxiety, depressive, and somatic symptoms in older medical patients with generalized anxiety disorder (GAD). A case-control study was designed and conducted in the University of California, San Diego (UCSD) Geriatrics Clinics. A total of fifty-four older medical patients with GAD and 54 matched controls participated. The measurements used for this study include: Brief Symptom Inventory-18, Mini International Neuropsychiatric Interview, and the Anxiety Disorders Interview Schedule. Older medical patients with GAD reported higher levels of somatic symptoms, anxiety, and depression than other older adults, as well as higher rates of diabetes and gastrointestinal conditions. In a multivariate model that included somatic symptoms, medical conditions, and depressive and anxiety symptoms, anxiety symptoms were the only significant predictors of GAD. These results suggest first, that older medical patients with GAD do not primarily express distress as somatic symptoms; second, that anxiety symptoms in geriatric patients should not be discounted as a byproduct of medical illness or depression; and third, that older adults with diabetes and gastrointestinal conditions may benefit from screening for anxiety.

    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.

    Episodes of anxiety have been reported to be the most common psychological symptoms in patients with partial seizures. They may occur before, during and after seizures and can also appear in isolation without any convulsive symptoms. The epileptic anxiety syndrome is strikingly similar to panic attacks, and panic disorder is an important differential diagnosis. The close relationship between epileptic seizures and panic attacks is of special interest for a better pathophysiological understanding of panic attacks. In the literature an epileptiform neuronal activity is discussed as a possible underlying mechanism for panic disorder. The finding that anxiety was the most common experiential phenomenon produced by electrical stimulation of amygdala and hippocampus with depth electrodes points in this direction. PET has demonstrated abnormalities of hippocampal structures during the nonpanic state of patients with panic disorder. In addition, some EEG studies have demonstrated a high incidence of epileptiform EEG patterns in patients with panic disorder with or without agoraphobia. This was the reason why several investigators proposed that a subset of panic attacks may be related to abnormal epileptiform neuronal activity in the limbic system. The size of this subset is difficult to determine because discharges in the depth of the limbic system often cannot be seen in the scalp EEG. Concerning the hypothetical pathophysiological mechanism of panic disorder therapeutic measures were taken with antiepileptic agents. The best results were obtained for valproic acid. It seems to be reasonable to make a therapeutic trial with antiepileptic medication after nonresponse to standard pharmacotherapy.

    The fear conditioning and extinction neurocircuitry has been extensively studied in healthy and clinical populations, with a particular focus on posttraumatic stress disorder. Despite significant overlap of symptoms between posttraumatic stress disorder and anxiety disorders, the latter has received less attention. Given that dysregulated fear levels characterize anxiety disorders, examining the neural correlates of fear and extinction learning may shed light on the pathogenesis of underlying anxiety disorders. To investigate the psychophysiological and neural correlates of fear conditioning and extinction recall in anxiety disorders and to document how these features differ as a function of multiple diagnoses or anxiety severity. This investigation was a cross-sectional, case-control, functional magnetic resonance imaging study at an academic medical center. Participants were healthy controls and individuals with at least 1 of the following anxiety disorders: generalized anxiety disorder, social anxiety disorder, specific phobia, and panic disorder. The study dates were between March 2013 and May 2015. Two-day fear conditioning and extinction paradigm. Skin conductance responses, blood oxygenation level-dependent responses, trait anxiety scores from the State Trait Anxiety Inventory-Trait Form, and functional connectivity. This study included 21 healthy controls (10 women) and 61 individuals with anxiety disorders (36 women). P values reported for the neuroimaging results are all familywise error corrected. Skin conductance responses during extinction recall did not differ between individuals with anxiety disorders and healthy controls (ηp2 = 0.001, P = .79), where ηp2 is partial eta squared. The anxiety group had lower activation of the ventromedial prefrontal cortex (vmPFC) during extinction recall (ηp2 = 0.178, P = .02). A similar hypoactive pattern was found during early conditioning (ηp2 = 0.106, P = .009). The vmPFC hypoactivation

    Full Text Available Behavioral inhibition (BI increases vulnerability to develop anxiety disorders and is typified by avoidance and withdrawal from novel objects, people, and situations. The present study considered the relationship between behavioral inhibition and temperamental risk factors, such as trait anxiety and acquisition rate of a classically conditioned eyeblink response. 174 healthy undergraduate students (mean age 20.3 years, 71.8% female were given the State-Trait Anxiety Inventory and a battery of self-report measures of behavioral inhibition consisting of the Adult and Retrospective Measures of Behavioural Inhibition (AMBI/RMBI and the Concurrent and Retrospective Self Report of Inhibition (CSRI/RSRI. Participants then underwent standard delay classical eyeblink conditioning consisting of 45 trials with a 500-ms CS overlapping and co-terminating with a 10-ms airpuff US. Individuals with higher scores on the AMBI and Trait Anxiety Inventory, but not the other measures, showed faster acquisition of a conditioned eyeblink response than individuals with lower scores. Results support a relationship between facilitated acquisition of inter-stimulus relationships and risk for anxiety, and suggest that some measures assessing anxiety vulnerability better capture this relationship than others.

    Anxiety and depression frequently co-occur and may share similar deficits in the processing of emotional stimuli. High anxiety is associated with a failure in the acquisition and extinction of fear conditioning. Despite the supposed common deficits, no research has been conducted on fear acquisition and extinction in depression. The main aim of the present study was to investigate and compare fear acquisition and extinction in anxiety- and depression-prone participants. Non-clinical anxious, depressive, anxious-depressive and control participants performed a fear discrimination task. During acquisition, the CS+ predicted an aversive event (unconditioned stimulus, US) and the CS- safety (no US). During extinction, the CS+ was no longer followed by the US, rendering it (temporarily) into a safety signal. On each CS participants rated their US expectancy; skin conductance responses (SCRs) were measured throughout. The expectancy scores indicated that high anxiety resulted in less safety learning during acquisition and extinction; no effect of depression was observed. SCRs showed that high-anxiety persons displayed less discrimination learning (CS+ minus CS-) during acquisition than low-anxiety persons. During extinction, high-depression persons demonstrated more discriminative SCR than low-depression persons. The observed discrepancies in response patterns of high-anxiety and -depression persons seem to indicate distinctive information processing of emotional stimuli.

    The repeated discovery of adult dinosaurs in close association with egg clutches leads to speculation over the type and extent of care exhibited by these extinct animals for their eggs and young. To assess parental care in Cretaceous troodontid and oviraptorid dinosaurs, we examined clutch volume and the bone histology of brooding adults. In comparison to four archosaur care regressions, the relatively large clutch volumes of Troodon, Oviraptor, and Citipati scale most closely with a bird-paternal care model. Clutch-associated adults lack the maternal and reproductively associated histologic features common to extant archosaurs. Large clutch volumes and a suite of reproductive features shared only with birds favor paternal care, possibly within a polygamous mating system. Paternal care in both troodontids and oviraptorids indicates that this care system evolved before the emergence of birds and represents birds' ancestral condition. In extant birds and over most adult sizes, paternal and biparental care correspond to the largest and smallest relative clutch volumes, respectively.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2011v10n1p165 This paper aims to examine the relation between paternalism and antipaternalism. The original intention is disable the arguments seeking to justify acceptance on the part of Mill of moral and legal paternalism. The work will also investigate the concern milleans with the concepts of autonomy and self-development, positioning itself for a reading of Mill as a thinker who advocates a weak version of paternalism. This research suggests, moreover, the communication with the interpreters of contemporary Mill, which will assess the impact of their ideas on the current dialogue on the liberty and paternalism.

    Nearly 100 years ago, Ivan Pavlov demonstrated that dogs could learn to use a neutral cue to predict a biologically relevant event: after repeated predictive pairings, Pavlov's dogs were conditioned to anticipate food at the sound of a bell, which caused them to salivate. Like sustenance, danger is biologically relevant, and neutral cues can take on great salience when they predict a threat to survival. In anxiety disorders such as posttraumatic stress disorder (PTSD), this type of conditioned fear fails to extinguish, and reminders of traumatic events can cause pathological conditioned fear responses for decades after danger has passed. In this review, we use fear conditioning and extinction studies to draw a direct line from Pavlov to PTSD and other anxiety disorders. We explain how rodent studies have informed neuroimaging studies of healthy humans and humans with PTSD. We describe several genes that have been linked to both PTSD and fear conditioning and extinction and explain how abnormalities in fear conditioning or extinction may reflect a general biomarker of anxiety disorders. Finally, we explore drug and neuromodulation treatments that may enhance therapeutic extinction in anxiety disorders. PMID:24321650

    The aim of the current study was twofold: (1) to systematically examine differences in fear conditioning between anxiety patients and healthy controls using meta-analytic methods, and (2) to examine the extent to which study characteristics may account for the variability in findings across studies. Forty-four studies (published between 1920 and 2013) with data on 963 anxiety disordered patients and 1,222 control subjects were obtained through PubMed and PsycINFO, as well as from a previous meta-analysis on fear conditioning (Lissek et al.). Results demonstrated robustly increased fear responses to conditioned safety cues (CS-) in anxiety patients compared to controls during acquisition. This effect may represent an impaired ability to inhibit fear in the presence of safety cues (CS-) and/or may signify an increased tendency in anxiety disordered patients to generalize fear responses to safe stimuli resembling the conditioned danger cue (CS+). In contrast, during extinction, patients show stronger fear responses to the CS+ and a trend toward increased discrimination learning (differentiation between the CS+ and CS-) compared to controls, indicating delayed and/or reduced extinction of fear in anxiety patients. Finally, none of the included study characteristics, such as the type of fear measure (subjective vs. psychophysiological index of fear), could account significantly for the variance in effect sizes across studies. Further research is needed to investigate the predictive value of fear extinction on treatment outcome, as extinction processes are thought to underlie the beneficial effects of exposure treatment in anxiety disorders. © 2015 Wiley Periodicals, Inc.

    The basolateral and lateral amygdala nuclei complex (BLC) is implicated in a number of emotional responses including conditioned fear and social anxiety. Based on previous studies demonstrating that enhanced serotonin release in the BLC leads to increased anxiety and fear responses, we hypothesized that pharmacologically depleting serotonin in the BLC using 5,7-dihydroxytryptamine (5,7-DHT) injections would lead to diminished anxiety and disrupted fear conditioning. To test this hypothesis, 5,7-DHT(a serotonin-depleting agent) was bilaterally injected into the BLC. Desipramine (a norepinephrine reuptake inhibitor) was systemically administered to prevent non-selective effects on norepinephrine. After 5days, 5-7-DHT-treated rats showed increases in the duration of social interaction (SI) time, suggestive of reduced anxiety-like behavior. We then used a cue-induced fear conditioning protocol with shock as the unconditioned stimulus and tone as the conditioned stimulus for rats pretreated with bilateral 5,7-DHT, or vehicle, injections into the BLC. Compared to vehicle-treated rats, 5,7-DHT rats had reduced acquisition of fear during conditioning (measured by freezing time during tone), also had reduced fear retrieval/recall on subsequent testing days. Ex vivo analyses revealed that 5,7-DHT reduced local 5-HT concentrations in the BLC by ~40% without altering local norepinephrine or dopamine concentrations. These data provide additional support for 5-HT playing a critical role in modulating anxiety-like behavior and fear-associated memories through its actions within the BLC.

    2007-12-01

    Paternity analysis using microsatellite information is a well-studied subject. These markers are ideal for parentage studies and fingerprinting, due to their high-discrimination power. This type of data is used to assign paternity, to compute the average selfing and outcrossing rates and to estimate the biparental inbreeding. There are several public domain programs that compute all this information from data. Most of the time, it is necessary to export data to some sort of format, feed it to the program and import the output to an Excel book for further processing. In this article we briefly describe a program referred from now on as Paternity Analysis in Excel (PAE), developed at IST and IBET (see the acknowledgments) that computes paternity candidates from data, and other information, from within Excel. In practice this means that the end user provides the data in an Excel sheet and, by pressing an appropriate button, obtains the results in another Excel sheet. For convenience PAE is divided into two modules. The first one is a filtering module that selects data from the sequencer and reorganizes it in a format appropriate to process paternity analysis, assuming certain conventions for the names of parents and offspring from the sequencer. The second module carries out the paternity analysis assuming that one parent is known. Both modules are written in Excel-VBA and can be obtained at the address (www.math.ist.utl.pt/~fmd/pa/pa.zip). They are free for non-commercial purposes and have been tested with different data and against different software (Cervus, FaMoz, and MLTR).

    Mindfulness-based interventions for depression and anxiety emphasize the importance of observing present moment experience, but observing has often been positively related to anxiety and unrelated to depression symptoms. The current study sought to better understand the conditions and mechanism through which observing relates to symptoms by examining six conditional process models in which (1) nonreactivity moderates the direct effect of observing on symptoms of anxiety and depression symptoms and (2) nonreactivity moderates the indirect effect of observing on anxiety and depression via cognitive emotion regulation strategies (i.e., rumination, worry, and reappraisal). A clinical sample of 189 adults with anxiety and depressive disorders completed the Five Facet Mindfulness Questionnaire, Mood and Anxiety Symptom Questionnaire, Penn State Worry Questionnaire, Ruminative Responses Scale, and Emotion Regulation Questionnaire. Conditional process models showed that nonreactivity significantly moderated the direct effect of observing on symptoms of depression, but not anxiety. Additionally, nonreactivity significantly moderated the indirect effect of observing on symptoms of depression through rumination and reappraisal, but not worry. For anxiety, nonreactivity significantly moderated the indirect effect of observing on symptoms through worry and rumination, but not reappraisal. Causal interpretations of results are limited. Findings suggest that the relationship between observing and symptoms of depression and anxiety depends on the capacity to observe nonreactively, which may influence symptoms directly and indirectly through cognitive emotion regulation strategies. Findings raise important implications for tailoring mindfulness-based treatments for anxiety and depression symptoms. Copyright © 2014 Elsevier B.V. All rights reserved.

    This study examined the role of hope in understanding the link between loneliness and negative affective conditions (viz., anxiety and depressive symptoms) in a sample of 318 adults. As expected, loneliness was found to be a significant predictor of both anxiety and depressive symptoms. Noteworthy, hope was found to significantly augment the prediction of depressive symptoms, even after accounting for loneliness. Furthermore, we found evidence for a significant Loneliness × Hope interaction effect in predicting anxiety. A plot of the interaction confirmed that the association between loneliness and anxiety was weaker among high, compared to low, hope adults. Some implications of the present findings are discussed.

    Maternal postpartum depression is a prevalent health disorder with important consequences to the family and child development. Research evidence demonstrates that fathers can also suffer from psychological distress in the postpartum period and that paternal depression has a detrimental effect on the child's behavioral and emotional development. This study aims to review the current literature available about birth-related paternal depression. A literature search from 1980 to 2007 was conducted through Medline electronic database, using the following Mesh terms: postpartum, postnatal, depression, fathers and paternal. Studies on maternal postpartum depression that examined issues related to paternal depression were also selected. Understanding about paternal depressive disorders during the postnatal period has advanced considerably in the last decade. Various studies demonstrate that birth-related paternal depression is a significant problem and closely associated with maternal depressive symptoms. Children of depressive fathers are also at risk for emotional and behavioral problems. Men may suffer from psychological distress after childbirth and birth-related paternal depression is not a rare phenomenon. Since this disorder, also called 'paternal postpartum depression', presents potential deleterious effects for the child, an increased level of public health awareness and scientific interest is warranted. In addition, a more detailed assessment of fathers during the postnatal period is recommended, especially when their partners are also depressed, so that the condition will be promptly recognized and treated.

    To study the etiology of public speaking anxiety (speech phobia), 30 Ss with the fear of public speaking, and 24 controls without this fear were asked about past public speaking experiences, their beliefs about the main reason for their phobia, and their concerns in the feared situation. All speech phobics met the DSM-III-R criteria for social phobia. Results showed that traumatic external events, vicarious and informational learning--the causes for phobia that fit in best with Rachman's conditioning theory--were notably uncommon among these phobics, who attributed their fear most often to panic attacks. Yet it was not clear whether panic attacks were causes or consequences of phobia.

    The emphasis on the necessity for fully informed consent in two new books, Doctors' Dilemmas by M. Phillips and J. Dawson and Whose Body Is It? by C. Faulder, is found to be "lacking in balance" by Brewin. The doctor's discretion in dealing with each patient is considered to be the key to determining priorities between paternalism and communication. Rigid rules, Brewin argues, may not be in the patient's best interest and thus should not be forced on doctors and nurses by "philosophers or experts in ethics."

    Recent studies have demonstrated that behavioral traits are subject to transgenerational modification by paternal environmental factors. We previously reported on the transgenerational influences of increased paternal stress hormone levels on offspring anxiety and depression-related behaviors. Here, we investigated whether offspring sociability and cognition are also influenced by paternal stress. Adult C57BL/6J male mice were treated with corticosterone (CORT; 25mg/L) for four weeks prior to paired-matings to generate F1 offspring. Paternal CORT treatment was associated with decreased body weights of female offspring and a marked reduction of the male offspring. There were no differences in social behavior of adult F1 offspring in the three-chamber social interaction test. Despite male offspring of CORT-treated fathers displaying hyperactivity in the Y-maze, there was no observable difference in short-term spatial working memory. Spatial learning and memory testing in the Morris water maze revealed that female, but not male, F1 offspring of CORT-treated fathers had impaired memory retention. We used our recently developed methodology to analyze the spatial search strategy of the mice during the learning trials and determined that the impairment could not be attributed to underlying differences in search strategy. These results provide evidence for the impact of paternal corticosterone administration on offspring cognition and complement the cumulative knowledge of transgenerational epigenetic inheritance of acquired traits in rodents and humans.

  8. Investigating the role of hippocampal BDNF in anxiety vulnerability using classical eyeblink conditioning

    Full Text Available Dysregulation of brain-derived neurotrophic factor (BDNF, behavioral inhibition temperament (BI and small hippocampal volume have been linked to anxiety disorders. Individuals with BI show facilitated acquisition of the classically conditioned eyeblink response (CCER as compared to non-BI individuals, and a similar pattern is seen in an animal model of BI, the Wistar-Kyoto (WKY rat. The present study examined the role of hippocampal BDNF in the facilitated delay CCER of WKY rats. Consistent with earlier work, acquisition was facilitated in WKY rats compared to the SD rats. Facilitated acquisition was associated with increased BDNF, TrkB, and Arc mRNA in the dentate gyrus of SD rats, but learning-induced increases in BDNF and Arc mRNA were significantly smaller in WKY rats. To determine if reduced hippocampal BDNF in WKY rats was a contributing factor for their facilitated CCER, BDNF or saline infusions were given bilaterally into the dentate gyrus region one hour prior to training. BDNF infusion did not alter the acquisition of SD rats, but significantly dampened the acquisition of CCER in the WKY rats, such that acquisition was similar to SD rats. Together, these results suggest that inherent differences in the BDNF system play a critical role in the facilitated associative learning exhibited by WKY rats, and potentially individuals with BI. Facilitated associative learning may represent a vulnerability factor in the development of anxiety disorders.

    Although there is a growing body of research concerning the prevalence and correlates of chronic pain conditions and their association with mental disorders, cross-national research on age and gender differences is limited. The present study reports the prevalence by age and gender of common chronic pain conditions (headache, back or neck pain, arthritis or joint pain, and other chronic pain) in 10 developed and 7 developing countries and their association with the spectrum of both depressive and anxiety disorders. It draws on data from 18 general adult population surveys using a common survey questionnaire (N = 42,249). Results show that age-standardized prevalence of chronic pain conditions in the previous 12 months was 37.3% in developed countries and 41.1% in developing countries, with back pain and headache being somewhat more common in developing than developed countries. After controlling for comorbid chronic physical diseases, several findings were consistent across developing and developed countries. There was a higher prevalence of chronic pain conditions among females and older persons; and chronic pain was similarly associated with depression-anxiety spectrum disorders in developed and developing countries. However, the large majority of persons reporting chronic pain did not meet criteria for depression or anxiety disorder. We conclude that common pain conditions affect a large percentage of persons in both developed and developing countries. Chronic pain conditions are common in both developed and developing countries. Overall, the prevalence of pain is greater among females and among older persons. Although most persons reporting pain do not meet criteria for a depressive or anxiety disorder, depression/anxiety spectrum disorders are associated with pain in both developed and developing countries.

  11. Increasing paternal responsibility.

    Science.gov (United States)

    Cutright, P

    1985-01-01

    Increasing numbers of fathers of children born out of wedlock are not contributing to these children's economic support. In 1981, a tiny minority (14%) of the 1.7 million never-married mothers living with a child with an absent father had a child-support award, and of these, just 112,000 actually received some payment in 1981. The high rates of noncompliance, and the low level of legal efforts to enforce child support, are the result of attempts to collect payments through inefficient traditional methods, not the inability of fathers to pay, a Wisconsin study has shown. A basic problem with collecting child support under the present system is that it relies on fathers to control their expenditures and voluntarily to send the payment on a weekly, biweekly or monthly basis, year after year. As a Wisconsin study shows, full compliance with court-ordered payments dropped from 38% in the 1st year to below 20% by the 5th year among 163 ex-husbands tracked. A proposal by researchers at the University of Wisconsin's Institute for Research on Poverty calls for an "absent-parent tax." The Wisconsin Plan, as it is known, is simply a withholding tax based on the father's gross income and the number of his absent children. If his income falls below a certain level, payments will stop automatically, but will resume if and when it rises above the cutoff point. The Wisconsin plan removes all judicial discretion and lawyer's skill as factors in child-support awards, thus eliminating erratic awards. It also insures that support payments will be maintained during periods of conflict between the father and mother. However, before the Wisconsin Plan can effectively protect children both out of wedlock, a feature needs to be added that will establish paternity at birth. Imposing a real child-support obligation on fathers of children born outside of marriage will introduce a potentially powerful economic incentive for responsible male reproductive and parental behavior.

    Experts have proposed removing obsessive-compulsive disorder (OCD) from the anxiety disorders section and grouping it with putatively related conditions in DSM-5. The current study uses co-morbidity and familiality data to inform these issues. Case family data from the OCD Collaborative Genetics Study (382 OCD-affected probands and 974 of their first-degree relatives) were compared with control family data from the Johns Hopkins OCD Family Study (73 non-OCD-affected probands and 233 of their first-degree relatives). Anxiety disorders (especially agoraphobia and generalized anxiety disorder), cluster C personality disorders (especially obsessive-compulsive and avoidant), tic disorders, somatoform disorders (hypochondriasis and body dysmorphic disorder), grooming disorders (especially trichotillomania and pathological skin picking) and mood disorders (especially unipolar depressive disorders) were more common in case than control probands; however, the prevalences of eating disorders (anorexia and bulimia nervosa), other impulse-control disorders (pathological gambling, pyromania, kleptomania) and substance dependence (alcohol or drug) did not differ between the groups. The same general pattern was evident in relatives of case versus control probands. Results in relatives did not differ markedly when adjusted for demographic variables and proband diagnosis of the same disorder, though the strength of associations was lower when adjusted for OCD in relatives. Nevertheless, several anxiety, depressive and putative OCD-related conditions remained significantly more common in case than control relatives when adjusting for all of these variables simultaneously. On the basis of co-morbidity and familiality, OCD appears related both to anxiety disorders and to some conditions currently classified in other sections of DSM-IV.

  14. Repeated exposure to conditioned fear stress increases anxiety and delays sleep recovery following exposure to an acute traumatic stressor

    Full Text Available Repeated stressor exposure can sensitize physiological responses to novel stressors and facilitate the development of stress-related psychiatric disorders including anxiety. Disruptions in diurnal rhythms of sleep-wake behavior accompany stress-related psychiatric disorders and could contribute to their development. Complex stressors that include fear-eliciting stimuli can be a component of repeated stress experienced by humans, but whether exposure to repeated fear can prime the development of anxiety and sleep disturbances is unknown. In the current study, adult male F344 rats were exposed to either control conditions or repeated contextual fear conditioning for 22 days followed by exposure to either no, mild (10, or severe (100 acute uncontrollable tail shock stress. Exposure to acute stress produced anxiety-like behavior as measured by a reduction in juvenile social exploration and exaggerated shock-elicited freezing in a novel context. Prior exposure to repeated fear enhanced anxiety-like behavior as measured by shock-elicited freezing, but did not alter social exploratory behavior. The potentiation of anxiety produced by prior repeated fear was temporary; exaggerated fear was present 1 day but not 4 days following acute stress. Interestingly, exposure to acute stress reduced REM and NREM sleep during the hours immediately following acute stress. This initial reduction in sleep was followed by robust REM rebound and diurnal rhythm flattening of sleep / wake behavior. Prior repeated fear extended the acute stress-induced REM and NREM sleep loss, impaired REM rebound, and prolonged the flattening of the diurnal rhythm of NREM sleep following acute stressor exposure. These data suggest that impaired recovery of sleep / wake behavior following acute stress could contribute to the mechanisms by which a history of prior repeated stress increases vulnerability to subsequent novel stressors and stress-related disorders.

    Today's stressors largely arise from social interactions rather than from physical threat. However, the dominant laboratory model of emotional learning relies on physical stimuli (e.g. electric shock) whereas adequate models of social conditioning are missing, possibly due to more subtle and multilayered biobehavioral responses to such stimuli. To fill this gap, we acquired a broad set of measures during conditioning to negative social unconditioned stimuli, also taking into account long-term maintenance of conditioning and inter-individual differences. Fifty-nine healthy participants underwent a classical conditioning task with videos of actors expressing disapproving (US-neg) or neutral (US-neu) statements. Static images of the corresponding actors with a neutral facial expression served as CS+ and CS-, predicting US-neg and US-neu, respectively. Autonomic and facial-muscular measures confirmed differential unconditioned responding whereas experiential CS ratings, event-related potentials, and evoked theta oscillations confirmed differential conditioned responding. Conditioning was maintained at 1 month and 1 year follow-ups on experiential ratings, especially in individuals with elevated anxiety and depressive symptoms, documenting the efficiency of social conditioning and its clinical relevance. This novel, ecologically improved conditioning paradigm uncovered a remarkably efficient multi-layered social learning mechanism that may represent a risk factor for anxiety and depression. © The Author (2016).

    Mating systems, as an evolutionary stable strategy, play an important role in animal reproductive process and result from an animal's adaption to their environment, including their inter-specific environment. In the 1980s, extrapair paternity (EPP) was first noted in the eurychoric species, the Great Tit, Parus major. As earlier studies indicated, morphology, physiology, behavior, ecological characteristics and mating systems of eurychoric species differ greatly between areas or populations. Accordingly, we analyzed the mating system of the Great Tit (P.m.minor) in Fairy Cave National Nature Reserve, Liaoning, China. We collected total parent-offspring blood samples from 22 broods. We used 8 hypervariable loci, which were selected from 11 reported microsatellite loci for paternity test. In conjunction with the known genetic pattern of the female parent, the accuracy of the paternity testing reached 99.98% with this genetic data. Results of paternity testing showed that 7 of 22 broods (31.8%) had extra-pair nestling, with 16 of 197 nestlings (8.12%) a result of extra-pair fertilizations. The EPP rate of the Great Tit we noted in Liaoning is obviously lower than those in other passerine forest birds (less than 10%). Though between 55.6% and 9.1% extrapair offspring were found among the different nests, we were, however, unable to find any explanatory rule.

    Rodent studies have demonstrated that adolescent social isolation results in many behavioral perturbations, including increases in anxiety-like behaviors. Socially isolated (SI) rats have also been shown to self-administer greater amounts ethanol (EtOH) in some, but not all, studies. Here, we tested whether juvenile social isolation increases EtOH drinking using an intermittent procedure that engenders relatively high intake in normally reared animals. We also compared the behavioral phenotype of rats reared under social isolation or group-housed conditions with adult rats housed under conditions commonly used in EtOH-drinking studies. Male Long Evans rats were procured immediately postweaning and were group housed for 1 week. Subjects were then randomly divided into 2 groups: SI rats, housed individually for 6 weeks and group-housed (GH) rats (4/cage). A third group was procured as young adults and was housed individually upon arrival for 1 week (standard housing condition). Rats were then tested in a plus-maze and novelty assay, and then, all subjects were singly housed and EtOH drinking was assessed. SI rats displayed increased anxiety-like behaviors on the plus-maze, a greater locomotor response to a novel environment, and increased EtOH intake, relative to GH rats. Age-matched standard housed (STD) rats exhibited an anxiety-like behavioral profile on the plus-maze that was similar to SI, and not GH rats, and also drank EtOH at levels comparable with SI subjects. In addition, anxiety-like behavior on the plus-maze correlated with intermittent EtOH intake in SI and GH rats. These data further support the validity of the rodent juvenile social isolation model for studies directed at elucidating behavioral and neurobiological mechanisms linking anxiety and EtOH drinking. These findings further suggest that housing conditions commonly employed in rodent drinking studies may recapitulate the anxiety-like and EtOH-drinking phenotype engendered by a juvenile social

    Fear- and anxiety-related psychiatric disorders have been one of the major chronic diseases afflicting patients for decades, and new compounds for treating such disorders remain to be developed. (+)-Borneol, a bicyclic monoterpene found in several species of Artemisia and Dipterocarpaceae, is widely used for anxiety, pain and anesthesia in Chinese medicine. Meanwhile, it can potentiate GABA (γ-aminobutyric acid) activity directly in recombinant GABAA receptors. The present study was to investigate the effects of (+)-Borneol on both contextual and cued fear recall. Interestingly, microinjection of (+)-Borneol into the dorsal hippocampus inhibited 24 h and 7 d contextual fear, whereas its infusion into ventral hippocampus only reduced 24 h cued fear responses. Moreover, microinjection of (+)-Borneol into dorsal but not ventral hippocampus suppressed anxiety-like behaviors in the open field test, light/dark exploration and the elevated plus maze test. As selective GABA A receptor antagonist bicuculline reversed the effect of (+)-Borneol on contextual fear paradigm and the drug potentiated GABA-evoked currents in acute hippocampus slices, modulation of the GABAergic neurotransmission may explain the effects of (+)-Borneol. Our findings suggest that (+)-Borneol can serve as a new therapeutic in fear- and anxiety-related disorders. Copyright © 2017 Elsevier Inc. All rights reserved.

    Identifying early markers of risk for anxiety disorders in children may aid in understanding underlying mechanisms and informing prevention efforts. Affective modulation of the startle response indexes sensitivity to pleasant and unpleasant environmental contexts and has been shown to relate to anxiety, yet the extent to which abnormalities in affect-modulated startle reflect vulnerability for anxiety disorders in children has yet to be examined. The current study assessed the effects of parental psychopathology on affective modulation of startle in offspring. Nine-year-old children (n = 144) with no history of anxiety or depressive disorders completed a passive picture viewing task in which eye-blink startle responses were measured during the presentation of pleasant, neutral, and unpleasant images. Maternal anxiety was associated with distinct patterns of affective modulation of startle in offspring, such that children with maternal histories of anxiety showed potentiation of the startle response while viewing unpleasant images, but not attenuation during pleasant images, whereas children with no maternal history of anxiety exhibited attenuation of the startle response during pleasant images, but did not exhibit unpleasant potentiation - even when controlling for child symptoms of anxiety and depression. No effects of maternal depression or paternal psychopathology were observed. These findings suggest that both enhanced startle responses in unpleasant conditions and failure to inhibit startle responses in pleasant conditions may reflect early emerging vulnerabilities that contribute to the later development of anxiety disorders.

    Fear allows organisms to cope with dangerous situations and remembering these situations has an adaptive role preserving individuals from injury and death. However, recalling traumatic memories can induce re-experiencing the trauma, thus resulting in a maladaptive fear. A failure to properly regulate fear responses has been associated with anxiety disorders, like Posttraumatic Stress Disorder (PTSD). Thus, re-establishing the capability to regulate fear has an important role for its adaptive and clinical relevance. Strategies aimed at erasing fear memories have been proposed, although there are limits about their efficiency in treating anxiety disorders. To re-establish fear regulation, here we propose a new approach, based on the re-evaluation of the aversive value of traumatic experience. Mice were submitted to a contextual-fear-conditioning paradigm in which a neutral context was paired with an intense electric footshock. Three weeks after acquisition, conditioned mice were treated with a less intense footshock (pain threshold). The effectiveness of this procedure in reducing fear expression was assessed in terms of behavioral outcomes related to PTSD (e.g., hyper-reactivity to a neutral tone, anxiety levels in a plus maze task, social avoidance, and learning deficits in a spatial water maze) and of amygdala activity by evaluating c-fos expression. Furthermore, a possible role of lateral orbitofrontal cortex (lOFC) in mediating the behavioral effects induced by the re-evaluation procedure was investigated. We observed that this treatment: (i) significantly mitigates the abnormal behavioral outcomes induced by trauma; (ii) persistently attenuates fear expression without erasing contextual memory; (iii) prevents fear reinstatement; (iv) reduces amygdala activity; and (v) requires an intact lOFC to be effective. These results suggest that an effective strategy to treat pathological anxiety should address cognitive re-evaluation of the traumatic experience mediated

    Genetic disposition modulates the psychoactive effects of cannabis. Cannabinoids have a greater impact on brain regions that subserve anxiety in Wistar compared to Lewis strain rats. Here we aim to show that this correlates with strain differences in cannabinoid-induced anxiety-related behaviour. Lewis and Wistar rats were administered vehicle or the synthetic cannabinoid receptor agonist, CP 55,940 (10, 25 and 50μg/kg) before testing in the conditioned ultrasonic vocalization (USV), cat odour avoidance or open area avoidance models. Animals were placed in a chamber in which they had previously received footshock. Wistar but not Lewis rats re-exposed under the influence of all CP 55,940 doses emitted significantly more USVs than vehicle-treated rats. In the cat odour avoidance model, rats were exposed to cat odour and given the opportunity to hide in a small box. In Wistar but not Lewis rats, 50μg/kg of CP 55,940 magnified hiding behaviour promoted by cat odour exposure. Animals were also tested in the open area avoidance model which occurred in the same arena as the predatory avoidance model but without cat odour. In Wistar, but not Lewis rats, 25 and 50μg/kg of CP 55,940 increased the avoidance of the open space. CP 55,940 increased anxiety-related behaviour in Wistar rats but not Lewis rats providing a model to dissect the genetic basis of cannabinoid-induced anxiety. We show for the first time that cannabinoids magnify conditioned USVs and cat odour avoidance behaviour dependent on the strain being tested. Crown Copyright © 2010. Published by Elsevier Inc.

    To determine whether older paternal age increases the risk of fathering a pregnancy with Patau (trisomy 13), Edwards (trisomy 18), Klinefelter (XXY) or XYY syndrome. Case-control: cases with each of these syndromes were matched to four controls with Down syndrome from within the same congenital anomaly register and with maternal age within 6 months. Data from 22 EUROCAT congenital anomaly registers in 12 European countries. Diagnoses with observed or (for terminations) predicted year of birth from 1980 to 2005, comprising live births, fetal deaths with gestational age ≥ 20 weeks and terminations after prenatal diagnosis of the anomaly. Data include 374 cases of Patau syndrome, 929 of Edwards syndrome, 295 of Klinefelter syndrome, 28 of XYY syndrome and 5627 controls with Down syndrome. Odds ratio (OR) associated with a 10-year increase in paternal age for each anomaly was estimated using conditional logistic regression. Results were adjusted to take account of the estimated association of paternal age with Down syndrome (1.11; 95% CI 1.01 to 1.23). The OR for Patau syndrome was 1.10 (95% CI 0.83 to 1.45); for Edwards syndrome, 1.15 (0.96 to 1.38); for Klinefelter syndrome, 1.35 (1.02 to 1.79); and for XYY syndrome, 1.99 (0.75 to 5.26). There was a statistically significant increase in the odds of Klinefelter syndrome with increasing paternal age. The larger positive associations of Klinefelter and XYY syndromes with paternal age compared with Patau and Edwards syndromes are consistent with the greater percentage of these sex chromosome anomalies being of paternal origin.

    We designed a gait training study that presented combinations of visual flow and support surface manipulations to investigate the response of healthy adults to novel discordant sensorimotor conditions. We aimed to determine whether a relationship existed between subjects visual dependence and their scores on a collective measure of anxiety, cognition, and postural stability in a new discordant environment presented at the conclusion of training (Transfer Test). A treadmill was mounted to a motion base platform positioned 2 m behind a large visual screen. Training consisted of three walking sessions, each within a week of the previous visit, that presented four 5-minute exposures to various combinations of support surface and visual scene manipulations, all lateral sinusoids. The conditions were scene translation only, support surface translation only, simultaneous scene and support surface translations in-phase, and simultaneous scene and support surface translations 180 out-of-phase. During the Transfer Test, the trained participants received a 2-minute novel exposure. A visual sinusoidal roll perturbation, with twice the original flow rate, was superimposed on a sinusoidal support surface roll perturbation that was 90 out of phase with the scene. A high correlation existed between normalized torso translation, measured in the scene-only condition at the first visit, and a combined measure of normalized heart rate, stride frequency, and reaction time at the transfer test. Results suggest that visually dependent participants experience decreased postural stability, increased anxiety, and increased reaction times compared to their less visually dependent counterparts when negotiating novel discordant conditions.

  8. High Correlated Paternity Leads to Negative Effects on Progeny Performance in Two Mediterranean Shrub Species.

    Directory of Open Access Journals (Sweden)

    Sofia Nora

    Full Text Available Anthropogenic habitat deterioration can promote changes in plant mating systems that subsequently may affect progeny performance, thereby conditioning plant recruitment for the next generation. However, very few studies yet tested mating system parameters other than outcrossing rates; and the direct effects of the genetic diversity of the pollen received by maternal plants (i.e. correlated paternity has often been overlooked. In this study, we investigated the relation between correlated paternity and progeny performance in two common Mediterranean shrubs, Myrtus communis and Pistacia lentiscus. To do so, we collected open-pollinated progeny from selected maternal plants, calculated mating system parameters using microsatellite genotyping and conducted sowing experiments under greenhouse and field conditions. Our results showed that some progeny fitness components were negatively affected by the high correlated paternity of maternal plants. In Myrtus communis, high correlated paternity had a negative effect on the proportion and timing of seedling emergence in the natural field conditions and in the greenhouse sowing experiment, respectively. In Pistacia lentiscus, seedling emergence time under field conditions was also negatively influenced by high correlated paternity and a progeny survival analysis in the field experiment showed greater mortality of seedlings from maternal plants with high correlated paternity. Overall, we found effects of correlated paternity on the progeny performance of Myrtus communis, a self-compatible species. Further, we also detected effects of correlated paternity on the progeny emergence time and survival in Pistacia lentiscus, an obligate outcrossed species. This study represents one of the few existing empirical examples which highlight the influence that correlated paternity may exert on progeny performance in multiple stages during early seedling growth.

    Social anxiety disorder is characterized by marked interpersonal impairment, particularly when presenting with comorbid major depression. However, the foundational social-cognitive skills that underlie interpersonal impairment in comorbid and non-comorbid manifestations of SAD has to date received very little empirical investigation. In a sample of 119 young adults, the current study examined differences in theory of mind (ToM), defined as the ability to decode and reason about others' mental states, across four groups: (a) non-comorbid SAD; (b) non-comorbid Lifetime MDD; (c) comorbid SAD and Lifetime MDD; and (d) healthy control. The non-comorbid SAD group was significantly less accurate at decoding mental states than the non-comorbid MDD and control groups. Further, both the comorbid and non-comorbid SAD groups made significantly more 'excessive' ToM reasoning errors than the non-comorbid MDD group, suggesting a pattern of over-mentalizing. Findings are discussed in terms of their implications for understanding the social cognitive foundations of social anxiety. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Prior research has consistently documented a strong association between generalized anxiety disorder (GAD) and substance use disorder (SUD). Comorbidity of GAD and SUD (GAD-SUD) represents clinical challenges, as the patients' symptoms are often more severe and are frequently prolonged, making their management more complex when compared with individuals with GAD only. The purpose of this study was to examine whether individuals with GAD-SUD differ meaningfully from individuals with GAD and no SUD comorbidity (GAD-NSUD) in terms of demographic characteristics, risk factors, psychiatric comorbidity, and clinical correlates. Data were derived from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (N = 43,093). Diagnoses were made using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version. We found that the lifetime prevalence rate of GAD-SUD is about 2.04%, while that of GAD-NSUD is 2.10%. Individuals with GAD-SUD showed higher psychiatric comorbidity rates than those with GAD-NSUD. Treatment-seeking rates for GAD are equally low in individuals with GAD-SUD and GAD-NSUD. Both groups were as likely to receive pharmacologic treatment for anxiety. The findings of our study indicate that individuals with GAD-SUD constitute half of the lifetime prevalence of GAD and that GAD-SUD is associated with high overall vulnerability for additional psychopathology, particularly in the externalizing spectrum; higher disability; and higher use of alcohol and drugs to relieve anxiety symptoms. © Copyright 2010 Physicians Postgraduate Press, Inc.

    In Switzerland paternity investigations are carried out using DNA analysis only since 1991. DNA patterns are inherited and only with the exception of genetically identical twins they are different in everyone and therefore unique to an individual. Hence DNA-systems are an excellent tool to resolve paternity disputes. DNA polymorphisms used for paternity diagnosis are length polymorphisms of the highly polymorphic VNTR loci [variable number of tandem repeats]. The most frequently applied systems are the DNA single locus systems. In addition to the DNA single locus systems the application of PCR (PCR = polymerase chain reaction) based DNA systems has increased particularly in difficult deficiency cases or in cases where only small evidential samples or partially degraded DNA are available. Normally four independent DNA single probes are used to produce a DNA profile from the mother, the child and the alleged father. A child inherits half the DNA patterns from its mother and the other half from its true biological father. If an alleged father doesn't possess the paternal specific DNA pattern in his DNA profile he is excluded from the paternity. In case of non-exclusion the probability for paternity is calculated according to Essen-Möller. When applying four highly polymorphic DNA single locus systems the biostatistical evaluation leads always to W-values exceeding 99.8% [= required value for positive proof of paternity]. DNA analysis is currently the best available method to achieve such effective conclusions in paternity investigations.

    2014-10-01

    Full Text Available The aim of this paper is to present an understanding of the coping mechanisms and coping styles adopted by individuals on the Autism Spectrum Conditions (ASC by looking to draw parallels with sports performance psychology and how different sources of stress and anxiety can lead to the adoption of different coping styles. Firstly, an overview of current understanding of what constitute a stressor and how this can affect an individual is presented from sport and exercise psychology literature. Secondly, a model of coping styles is illustrated with the aim to shed light at how different perceptions of levels of stress and anxiety are managed both on an individual and group level. Thirdly, within the context of this understanding, some examples about how to support individuals on the ASC will be illustrated. Finally, implications for future research and reflection will be presented by highlighting the importance of teaching and learning coping and tolerance skills as part of a comprehensive and holistic psycho-educational program.

    One qualitative study has reported that more paternal infant care and housework contributed to the maintenance of breastfeeding. However, few studies have quantitatively investigated these relationships. This study aimed to examine the association of paternal involvement in infant care and housework with exclusive breastfeeding during the first 6 months of life. Data from a population-based birth cohort study in Japan, the Longitudinal Survey of Babies in the 21st Century, were analyzed. We extracted information on infants who were singletons, term, normal birth weight, and living with both parents (n = 39 742). The associations between degree of paternal involvement in infant care and housework (high, middle, low) and breastfeeding patterns (exclusive, partial, formula only) were analyzed using ordered logistic regression adjusted for covariates. Maternal anxiety about childrearing was considered as a mediator. Compared with the low level of paternal infant care group, infants in the middle and high level groups were significantly less likely to have been breastfed (adjusted odds ratio: 0.90, 95% confidence interval [CI], 0.84-0.97; and 0.73, 95% CI, 0.67-0.79, respectively). In contrast, the amount of housework carried out by fathers was not associated with breastfeeding pattern. Maternal anxiety about childrearing did not attenuate the association between paternal infant care and breastfeeding. Paternal infant care was inversely associated with breastfeeding during the first 6 months of life. An additional intervention study about the importance of breastfeeding that aims to educate fathers who tend to involve themselves in infant care is needed.

    2017-08-01

    The antidepressant bupropion has received increasing attention as a pharmacological tool to treat addiction although little is known about its effects on social behaviour in adolescents. The present study aimed to evaluate if environmental housing conditions influence bupropion's actions on social behaviour of adolescent mice. Mice were either group- or individually housed for 2-weeks and then randomly divided into 2 cohorts: half of the mice remained in the initial housing condition and the other half were changed to isolated conditions for further 2-weeks. The following groups were compared: isolated/isolated (ISO/ISO), isolated/group-housed (ISO/GR), group-housed/isolated (GR/ISO), and group-housed/group-housed (GR/GR). The effects of bupropion (40, 20, 10mg/kg) or saline on social interaction were assessed for each housing condition. Social encounters were evaluated using ethological analysis. Data showed significant effects of bupropion on grooming and digging. This drug diminished time mice allocated to these behavioural categories in all housing conditions. In ISO/GR and GR/ISO conditions, bupropion increased environmental exploration (non-social exploration and exploration from a distance), reduced social investigation and increased avoidance/flee and defence/submission behaviours. An augment of avoidance/flee during social interactions was observed in bupropion-treated mice in GR/GR housing condition. These results suggest that this drug exhibits anxiogenic-like properties in social encounters between adolescent mice, especially when a transition in housing conditions has been experienced during this period. Changes in housing conditions may be a useful model for evaluating the effects of bupropion on social behaviour and the role of environmental housing conditions.

    Conditioned defeat is a model in Syrian hamsters (Mesocricetus auratus) in which normal territorial aggression is replaced by increased submissive and defensive behavior following acute social defeat. The conditioned defeat response involves both a fear-related memory for a specific opponent as well as anxiety-like behavior indicated by avoidance of novel conspecifics. We have previously shown that systemic injection of a 5-HT2a receptor antagonist reduces the acquisition of conditioned defeat. Because neural activity in the basolateral amygdala (BLA) is critical for the acquisition of conditioned defeat and BLA 5-HT2a receptors can modulate anxiety but have a limited effect on emotional memories, we investigated whether 5-HT2a receptor modulation alters defeat-induced anxiety but not defeat-related memories. We injected the 5-HT2a receptor antagonist MDL 11,939 (0 mM, 1.7 mM or 17 mM) or the 5-HT2a receptor agonist TCB-2 (0 mM, 8 mM or 80 mM) into the BLA prior to social defeat. We found that injection of MDL 11,939 into the BLA impaired acquisition of the conditioned defeat response and blocked defeat-induced anxiety in the open field, but did not significantly impair avoidance of former opponents in the Y-maze. Furthermore, we found that injection of TCB-2 into the BLA increased the acquisition of conditioned defeat and increased anxiety-like behavior in the open field, but did not alter avoidance of former opponents. Our data suggest that 5-HT2a receptor signaling in the BLA is both necessary and sufficient for the development of conditioned defeat, likely via modulation of defeat-induced anxiety.

    Social anxiety disorder (SAD) and antisocial personality disorder (ASPD) are not often thought of as being comorbid. However, recent research suggests the existence of a SAD subtype with characteristics atypical of SAD but common to ASPD. Thus, we explored two competing hypotheses: (1) SAD and ASPD represent opposite ends of a single dimension, or (2) SAD and ASPD exist on two separate dimensions that may be positively correlated. Data were obtained from the National Epidemiological Survey on Alcohol and Related Conditions. SAD-ASPD was related to greater impairment and psychiatric comorbidity than either disorder alone. The SAD-ASPD group was also more likely to seek treatment for their SAD symptoms and to drink before/during antisocial acts than the SAD only group. The presence of SAD for individuals with ASPD (and vice versa) does not appear to provide any "protective benefits." SAD and ASPD appear to be two separate but correlated disorders.

    Despite the considerable physical, emotional and social change that occurs during emerging adulthood, there is little research that examines the association between having a chronic health condition and mental disorder during this developmental period. The aims of this study were to examine the sex-specific prevalence of lifetime mental disorder in an epidemiological sample of emerging adults aged 15-30 years with and without chronic health conditions; quantify the association between chronic health conditions and mental disorder, adjusting for sociodemographic and health factors; and, examine potential moderating and mediating effects of sex, level of disability and pain. Data come from the Canadian Community Health Survey-Mental Health. Respondents were 15-30 years of age (n = 5947) and self-reported whether they had a chronic health condition. Chronic health conditions were classified as: respiratory, musculoskeletal/connective tissue, cardiovascular, neurological and endocrine/digestive. The World Health Organization Composite International Diagnostic Interview 3.0 was used to assess the presence of mental disorder (major depressive disorder, suicidal behaviour, bipolar disorder and generalised anxiety disorder). Lifetime prevalence of mental disorder was significantly higher for individuals with chronic health conditions compared with healthy controls. Substantial heterogeneity in the prevalence of mental disorder was found in males, but not in females. Logistic regression models adjusting for several sociodemographic and health factors showed that the individuals with chronic health conditions were at elevated risk for mental disorder. There was no evidence that the level of disability or pain moderated the associations between chronic health conditions and mental disorder. Sex was found to moderate the association between musculoskeletal/connective tissue conditions and bipolar disorder (β = 1.71, p = 0.002). Exploratory analyses suggest that the levels of

    Depression is common in people with long term conditions, and is associated with worse medical outcomes. Previous research shows perseverative negative thinking (e.g. worry, rumination) predicts subsequent depression and worse medical outcomes, suggesting interventions targeting perseverative negative thinking could improve depression and medical outcomes. Previous studies recruited healthy individuals, however. This review aimed to determine the temporal relationship and strength of prospective association of perseverative negative thinking with depression, anxiety and emotional distress in people with long term conditions. Four electronic databases were searched for studies including standardised measures of perseverative negative thinking and depression, anxiety or emotional distress, and which presented prospective associations. Findings were narratively synthesized. Thirty studies were identified in a range of long term conditions. Perseverative negative thinking and subsequent depression, anxiety or emotional distress were significantly correlated in the majority of studies (bivariate r=0.23 to r=0.73). 25 studies controlled for confounders, and in 15 perseverative negative thinking predicted subsequent depression, anxiety or emotional distress. Results varied according to condition and study quality. Six of 7 studies found bivariate associations between depression, anxiety or emotional distress and subsequent perseverative negative thinking, though 2 studies controlling for key covariates found no association. Few studies assessed the impact of perseverative negative thinking on medical outcomes. Strongest evidence supported perseverative negative thinking predicting subsequent depression, anxiety and emotional distress in people with long term conditions. Further prospective research is warranted to clarify the association of perseverative negative thinking with subsequent poor medical outcomes. Copyright © 2016 Elsevier Inc. All rights reserved.

    Early paternal behavior plays a critical role in behavioral development in monogamous species. The vast majority of laboratory studies investigating the influence of parental behavior on cocaine vulnerability focus on the effects of early maternal separation. However, comparable studies on whether early paternal deprivation influences cocaine-induced behavioral response are substantially lacking. Mandarin vole (Microtus mandarinus) is a monogamous rodent with high levels of paternal care. After mandarin vole pups were subjected to early paternal deprivation, acute cocaine- induced locomotion, anxiety- like behavior and social behavior were examined in 45day old female pups, while hypothalamic oxytocin immunoreactivity and serum oxytocin level were also assessed. We found that cocaine increased locomotion and decreased social investigation, contact behavior and serum oxytocin level regardless of paternal care. Cocaine increased anxiety levels and decreased oxytocin immunoreactive neurons of the paraventricular nuclei and supraoptic nuclei in the bi-parental care group, whilst there were no specific effects in the paternal deprivation group. These results indicate that paternal deprivation results in different behavioral response to acute cocaine exposure in adolescents, which may be in part associated with the alterations in oxytocin immunoreactivity and peripheral OT level.

    Fear-based disorders, like social anxiety disorder (SAD) and posttraumatic stress disorder (PTSD), are characterized by an exaggerated fear response and avoidance to trigger cues, suggesting a transdiagnostic mechanism of psychopathology. Current theories suggest that abnormalities in conditioned fear is a primary contributor to the pathophysiology of these disorders. The primary goal of this study was to compare acquisition of conditioned stimulus (CS) and aversive unconditioned stimulus (US) contingencies during fear learning and extinction in individuals with SAD and PTSD. In a standard Pavlovian fear conditioning-extinction paradigm we measured subjective US expectancy ratings to different CSs in patients with SAD (n=16) compared to patients with PTSD (n=13) and healthy controls (n=15) RESULTS: Both patient groups (SAD, PTSD) acquired differential conditioning between a CS that predicted US (CS+) and a CS that never predicted the US (CS-), however, both groups reported an increased expectancy that the US would occur following the CS-. Additionally, the PTSD group overestimated that the US would occur in general. Neither patient group showed evidence of successful extinction of the CS+-US contingency nor differentiated their expectation of US occurrence between the CS+ and CS- during extinction learning. Group sample sizes were small and we did not include a trauma-exposed group without PTSD CONCLUSIONS: Both SAD and PTSD generalize expectations of an aversive outcome across CSs, even when a CS never signals an aversive outcome and PTSD may tend to over-expect threat. Fear learning and extinction abnormalities may be a core feature underlying shared symptoms across fear-based disorders. Copyright © 2016 Elsevier B.V. All rights reserved.

    Advanced paternal age (APA) at conception has been linked with autism and schizophrenia in offspring, neurodevelopmental disorders that affect social functioning. The current study explored the effects of paternal age on social development in the general population. We used multilevel growth modeling to investigate APA effects on socioemotional development from early childhood until adolescence, as measured by the Strengths and Difficulties Questionnaire (SDQ) in the Twins Early Development Study (TEDS) sample. We also investigated genetic and environmental underpinnings of the paternal age effects on development, using the Additive genetics, Common environment, unique Environment (ACE) and gene-environment (GxE) models. In the general population, both very young and advanced paternal ages were associated with altered trajectory of social development (intercept: p = .01; slope: p = .03). No other behavioral domain was affected by either young or advanced age at fatherhood, suggesting specificity of paternal age effects. Increased importance of genetic factors in social development was recorded in the offspring of older but not very young fathers, suggesting distinct underpinnings of the paternal age effects at these two extremes. Our findings highlight that the APA-related deficits that lead to autism and schizophrenia are likely continuously distributed in the population.

  9. Multiple paternity in reptiles: patterns and processes.

    2008-06-01

    The evolution of female promiscuity poses an intriguing problem as benefits of mating with multiple males often have to arise via indirect, genetic, effects. Studies on birds have documented that multiple paternity is common in natural populations but strong evidence for selection via female benefits is lacking. In an attempt to evaluate the evidence more broadly, we review studies of multiple paternity in natural populations of all major groups of nonavian reptiles. Multiple paternity has been documented in all species investigated so far and commonly exists in over 50% of clutches, with particularly high levels in snakes and lizards. Marine turtles and lizards with prolonged pair-bonding have relatively low levels of multiple paternity but levels are nevertheless higher than in many vertebrates with parental care. There is no evidence that high levels of polyandry are driven by direct benefits to females and the evidence that multiple paternity arises from indirect genetic benefits is weak. Instead, we argue that the most parsimonious explanation for patterns of multiple paternity is that it represents the combined effect of mate-encounter frequency and conflict over mating rates between males and females driven by large male benefits and relatively small female costs, with only weak selection via indirect benefits. A crucial step for researchers is to move from correlative approaches to experimental tests of assumptions and predictions of theory under natural settings, using a combination of molecular techniques and behavioural observations.

  10. Paternity and inheritance of wealth

    Hartung, John

    1981-06-01

    One of the oldest conjectures in anthropology is that men transfer wealth to their sister's son when the biological paternity of their `own' children is in doubt1-12. Because maternity is certain, a man is necessarily related to his sister's son and his brother (see Fig. 1). It is argued here that relatedness to male heirs can be assured by passing wealth to sister's sons or down a line of brothers, whether the prevailing kinship system reckons those brothers matrilineally or patrilineally. It is also argued that when several transfers of wealth are considered, a man's likelihood of being cuckolded need not be unrealistically high13 for his successive matrilineal heirs to be more related to him than his successive patrilineal heirs (see Fig. 2). Cross-cultural data on sister's son/brother inheritance14 and frequency of extramarital sex for females15 support the hypothesis that men tend to transmit wealth to their sister's son and/or brother when the probability that their putative children are their genetic children is relatively low.

    To describe the prevalence of maternity and paternity among subjects and its association with perinatal, socioeconomic and demographic variables. The participants were youth, aged 23, on the average, accompanied in a cohort study since they were born, in 1982, in Pelotas (Southern Brazil) and interviewed in 2004-5. Those who were considered eligible referred having had one or more children, whether these were liveborns or stillborns. Data was collected on reproductive health as well as socioeconomic and demographic information, by means of two different instruments. The independent variables were sex and skin color, family income in 1982 and in 2004-5, changes in income, birth weight and educational level when aged 23 years old. Crude and adjusted analysis were conducted by means of Poisson regression so as to investigate the effects of the independent variables on maternity/paternity during adolescence. Among the 4,297 youth interviewed, 1,373 (32%) were parents and 842 (19.6%) of these had experienced maternity/paternity during their adolescence. Planned pregnancy of the first child was directly related to the youth's age. Socioeconomic variables were inversely related to the occurrence of maternity/paternity during adolescence. The probability of being an adolescent mother was higher among black and mixed skin colored women, but skin color was not associated to adolescent paternity. There was a strong relation between adolescent maternity/paternity and socioeconomic conditions, which should be taken into consideration when delineating preventive actions in the field of public health.

    Polyandry is common in many species and it has been suggested that females engage in multiple mating to increase the genetic diversity of their offspring (genetic diversity hypothesis). Multiple paternity occurs in 30% of litters in wild populations of house mice, Mus musculus musculus , and multiple-sired litters are genetically more diverse than single-sired ones. Here, we aimed to test whether female house mice produce multiple-sired litters when they have the opportunity to produce genetically diverse litters. We assessed the rates of multiple paternity when females could choose to mate with two males that were genetically dissimilar to each other (i.e. nonsiblings and MHC dissimilar) compared with when females could choose to mate with two males that were genetically similar to each other (i.e. siblings and shared MHC alleles). Multiple mating may depend upon a female's own condition, and, therefore, we also tested whether inbred (from full-sibling matings) females were more likely to produce multiple-sired progeny than outbred controls. Overall we found that 29% of litters had multiple sires, but we found no evidence that females were more likely to produce multiple-sired litters when they had the opportunity to mate with genetically dissimilar males compared with controls, regardless of whether females were inbred or outbred. Thus, our findings do not support the idea that female mice increase multiple paternity when they have the opportunity to increase the genetic diversity of their offspring, as expected from the genetic diversity hypothesis.

  13. Anxiety symptoms mediate the relationship between exposure to stressful negative life events and depressive symptoms: A conditional process modelling of the protective effects of resilience.

    Resilience has provided a useful framework that elucidates the effects of protective factors to overcome psychological adversities but studies that address the potential contingencies of resilience to protect against direct and indirect negative effects are lacking. These obvious gaps have also resulted in oversimplification of complex processes that can be clarified by moderated mediation associations. This study examines a conditional process modelling of the protective effects of resilience against indirect effects. Two separate samples were recruited in a cross-sectional survey from Australia and Norway to complete the Patient Health Questionnaire -9, Generalized Anxiety Disorder, Stressful Negative Life Events Questionnaire and the Resilience Scale for Adults. The final sample sizes were 206 (females=114; males=91; other=1) and 210 (females=155; males=55) for Australia and Norway respectively. Moderated mediation analyses were conducted across the samples. Anxiety symptoms mediated the relationship between exposure to stressful negative life events and depressive symptoms in both samples. Conditional indirect effects of exposure to stressful negative life events on depressive symptoms mediated by anxiety symptoms showed that high subgroup of resilience was associated with less effect of exposure to stressful negative life events through anxiety symptoms on depressive symptoms than the low subgroup of resilience. As a cross-sectional survey, the present study does not answer questions about causal processes despite the use of a conditional process modelling. These findings support that, resilience protective resources can protect against both direct and indirect - through other channels - psychological adversities. Copyright © 2017 Elsevier B.V.

    Dental anxiety is a common phenomenon influencing the relationship between a patient and a doctor as well as the course of treatment. The aim of the study was to assess the oral health status and hygiene habits among adult patients with respect to their level of dental anxiety. 117 consecutive adult patients referred to the Department of Conservative Dentistry and Paedodontics of Wroclaw Medical University were included in the study. There were 58 women (49.57%) and 59 men (50.43%). The mean age of the patients was 36.57 ± 16.76 years. The level of dental anxiety was assessed using the Modified Dental Anxiety Scale (MDAS). To evaluate dental health status and oral hygiene, the following indices were used: total number of decayed, missing and filled teeth (DMF/T) as well as surfaces (DMF/S), approximal plaque index (API), oral hygiene index (OHI), debris index (DI) and calculus index (CI). The study revealed that the patients with high MDAS presented a higher calculus index (CI). There was a negative correlation between a high level of dental anxiety measured by MDAS and the number of filled teeth (F/T) as well as the number of filled dental surfaces (F/S). There was no significant correlation between dental anxiety as measured with the MDAS and age, gender or level of education; however, smokers had a significantly higher anxiety level than non-smokers. Dental anxiety has a negative influence on oral health status; the higher the level of dental anxiety, the lower the number of filled teeth and the higher the calculus index. Poor dental and periodontal health may have many somatic as well as psychosocial consequences, both of which lower the quality of life of the patient.

    Studies in rats, involving hippocampal lesions and hippocampal drug infusions, have implicated the hippocampus in the modulation of anxiety-related behaviors and conditioned fear. The ventral hippocampus is considered to be more important for anxiety- and fear-related behaviors than the dorsal hippocampus. In the present study, we compared the role of dorsal and ventral hippocampus in innate anxiety and classical fear conditioning in Wistar rats, examining the effects of temporary pharmacological inhibition by the GABA-A agonist muscimol (0.5 ug/0.5 ul/side) in the elevated plus maze and on fear conditioning to a tone and the conditioning context. In the elevated plus maze, dorsal and ventral hippocampal muscimol caused distinct behavioral changes. The effects of ventral hippocampal muscimol were consistent with suppression of locomotion, possibly accompanied by anxiolytic effects, whereas the pattern of changes caused by dorsal hippocampal muscimol was consistent with anxiogenic effects. In contrast, dorsal and ventral hippocampal muscimol caused similar effects in the fear conditioning experiments, disrupting contextual, but not tone, fear conditioning.

    Full Text Available PurposeIn this study effects of a paternal participation program during cesarean section on paternal infant attachment were investigate. The experimental treatment was an integrative nursing intervention to promote father to infant attachment.MethodsStudy design was a non-equivalent control group posttest design. The program consisted of emotional support to spouse and father towards infant attachment immediately following cesarean birth. Participants were 66 men, partners of women with normal full term pregnancy having a cesarean section with spinal or epidural anesthesia, (experimental group, 34; control group, 32. The experiment was carried out from August 1 to October 30, 2010. Control group data were obtained from May 1 to June 30, 2012. Posttest was performed 72 hours after cesarean birth. A self-report questionnaire including a paternal attachment instrument was used. Data were analyzed using t-test, propensity score matching, and analysis of covariance with the SPSS/WIN 18.0 program.ResultsTotal score for paternal infant attachment in the experimental group was significantly higher than the control group (p<.001. After matching, significant differences were found between the two groups through all subcategories. Adjusted mean score for paternal infant attachment verified experimental effects.ConclusionResults indicate that this paternal participation program during cesarean section is effective in improving paternal infant attachment.

    Rodents solve dual-solution tasks that require navigation to a goal by adopting either a hippocampus-dependent place strategy or a striatum-dependent stimulus-response strategy. A variety of factors, including biological sex and emotional status, influence the choice of learning strategy. In these experiments, we investigated the relationship between learning strategy and anxiety level in male and female rats prior to the onset of puberty, before the activational effects of gonadal hormones influence these processes. In the first experiment, prepubertal male rats categorized as high in trait anxiety at 26days of age exhibited a bias toward stimulus-response strategy at 28days of age, whereas age-matched females exhibited no preference in strategy regardless of anxiety level. In the second experiment, male and female rats were separated from their dams for either 15 or 180min per day during the first 2weeks of life and tested on a battery of anxiety and cognitive tasks between 25 and 29days of age. Prolonged maternal separations for 180min were associated with impaired spatial memory on a Y-maze task in both prepubertal males and females. Furthermore, prolonged maternal separations were linked to elevated anxiety and a bias for stimulus-response strategy in prepubertal males but not females. Alternatively, brief separations from dams for 15min were associated with intact spatial memory, lower levels of anxiety, and no preference for either learning strategy in both sexes. These results provide evidence of sex-specific effects of trait anxiety and early maternal separation on the choice of learning strategy used by prepubertal rodents. Copyright © 2012 Elsevier Inc.

    approach to behaviour change relates to libertarian paternalism. This paper sets out to improve the clarity and value of the definition of nudge by reconciling it with its theoretical foundations in behavioural economics. In doing so it not only explicates the relationship between nudges and libertarian...... paternalism, but also clarifies how nudges relate to incentives and information, and may even be consistent with the removal of certain types of choices. In the end we are left with a revised definition of the concept of nudge that allows for consistently categorising behaviour change interventions...

    The study of mental disorders in people with chronic conditions recognises the importance of actively seeking and treating both, since chronic conditions have a higher prevalence than mental disorders and their comorbidity generates greater burden than if each one was considered separately. To measure the prevalence of mood disorders and anxiety in a Colombian population of 12 years and older and with and without different chronic conditions. The information is taken from the National Mental Health Survey 2015 in Colombia, which was an observational cross-sectional study with national representativeness for the age groups measured 12-17, 18-44, and 45 and older. Disorders measured where mood disorders and anxiety social phobia, generalised anxiety disorder, and panic disorder in the past 12 months, and several chronic conditions. Univariate and bivariate analyses were performed for these conditions. The highest prevalence of mood and anxiety disorders were found in people with gastrointestinal diseases, followed by those with chronic pain, heart, and lung diseases, which corresponded to 27.1%, 13.3%, 12.2%, and 11.5%, respectively, in those between 18 and 44 years old, and 15.9%, 12.2%, 8.0%, and 7.4% of those 45 and older, respectively. This was greater than the prevalence of these mental disorders in people with no chronic condition, where the prevalence is 3.5% in the younger, and 1.1% in the older group. However, the risk of these mental disorders is higher in older people. Thus, in those with gastrointestinal diseases when compared to people of the same age without any chronic condition the prevalence is 14.9 times higher, but for the same disease in the younger group it is 7.8. These findings link chronic conditions with a higher prevalence of mental disorders, which in the present study also highlights the greater comorbidity of mood and anxiety disorders in the elderly.

    2004-01-01

    Bird song is usually considered to have evolved in the context of sexual selection. Because extrapair paternity is a major component of sexual selection, mating advantages at the social level for males that produce songs of high quality may be transformed into higher success in extrapair paternity. Therefore, males with longer and more complex songs should suffer less from extrapair paternity intraspecifically, whereas species with high rates of extrapair paternity, reflecting intense sperm c...

    This study was designed to explore the role of perceived parenting style in the familial aggregation of anxiety disorders. We examined the association between parental and child anxiety diagnoses, and tested whether this association was partly due to a perceived parenting style. The study was conducted in a clinical sample as well as in a control sample. Parental lifetime and current anxiety diagnoses were significantly associated with child anxiety diagnoses. When maternal and paternal lifetime and current anxiety diagnoses were entered as separate predictors, only maternal current anxiety diagnoses appeared to be significant. Perceived parenting style was assessed with the dimensions "overprotection," "emotional warmth," "rejection," and "anxious rearing." Results indicated that only maternal and paternal 'overprotection' was significantly but negatively associated with child anxiety. However, further analyses showed that 'overprotection' did not have a significant mediating role in the familial aggregation of anxiety disorders.

    Parental psychopathology and parenting quality robustly predict negative outcomes among children with ADHD. Little research has investigated associations between paternal ADHD symptoms and parenting, though there is clear evidence linking maternal ADHD symptoms with both suboptimal parenting and child conduct problems, and considerable research supporting fathers' significant contributions to their children's development. This cross-sectional study examined psychopathology and parenting in a sample of fathers (N = 102) and their 5- to 12-year-old children with previously diagnosed ADHD. Results suggested that paternal antisocial personality disorder (ASPD) symptoms (rather than ADHD symptoms) were robustly associated with child conduct problems, with an indirect effect through paternal negative parenting. This study suggests that negative parenting may be a potential mechanism by which paternal ASPD is associated with child conduct problems, and demonstrates the importance of considering co-occurring psychopathology in research examining adult ADHD, parenting, and child outcomes. © The Author(s) 2015.

We identified all pregnancies in Denmark from 1994 to 2010 carried to a gestational age of at least 22 completed weeks (n = 944,031) as registered in national registers and linked to individual register data about the parents....... The hazard ratio of stillbirth according to paternal age was estimated, adjusted for maternal age in 1-year categories, year of outcome, and additionally parental educational levels. The relative rate of stillbirth (n = 4946) according to paternal age was found to be J-shaped with the highest hazard ratio.......41 (95% CI 1.26–1.59); 45–49, 1.20 (95% CI 0.97–1.49); 50+, 1.58 (95% CI 1.18–2.11), compared with fathers aged 30–34 years. These estimates attenuated slightly when further adjusted for parental education. Our study showed that paternal age was associated with the relative rate of stillbirth in a J...

    One predicted cost of female infidelity in socially monogamous species is that cuckolded males should provide less parental care. This relationship is robust across species, but evidence is ambiguous within species. We do not know whether individual males reduce their care when paired with cheating females compared with when paired with faithful females (within-male adjustment) or, alternatively, if the males that pair with cheating females are the same males that provide less parental care in general (between-male effect). Our exceptionally extensive long-term data set of repeated observations of a wild passerine allows us to disentangle paternal care adjustment within males-within pairs and between males-while accounting for environmental variables. We found a within-male adjustment of paternal provisioning, but not incubation effort, relative to the cuckoldry in their nest. This effect was mainly driven by females differing consistently in their fidelity. There was no evidence that this within-male adjustment also took place across broods with the same female, and we found no between-male effect. Interestingly, males that gained more extrapair paternity provided less care. Data from a cross-foster experiment suggested that males did not use kin recognition to assess paternity. Our results provide insight into the role of individual variation in parental care and mating systems.

    Recently, studies have begun emphasizing paternal involvement during the perinatal period and its impact on maternal health. However, most studies have assessed maternal perception and focused on adolescents or minority groups in Western countries. Therefore, the current study investigated the association between paternal involvement and maternal postnatal depression and anxiety, along with the effects of maternal job status in the Asian society of Taiwan. This study recruited pregnant women in the first trimester of pregnancy as well as their partners on prenatal visits from July 2011 to September 2013 at four selected hospitals in metropolitan areas of Taipei, Taiwan. In total, 593 parental pairs completed the first interview and responded to the follow-up questionnaires until 6 months postpartum. Self-reported data were collected, and multiple logistic regression models were used for analyses. Lower paternal childcare and nursing frequency was independently associated with an increased risk of maternal postpartum depression (adjusted odds ratio (OR) =4.33, 95% confidence interval (CI)=1.34-13.98), particularly among unemployed mothers. Furthermore, among unemployed mothers, the risk of postnatal anxiety was 3.14 times higher in couples with fathers spending less time with the child, compared with couples with fathers spending more time (95% CI=1.10-8.98). However, no significant findings were obtained for employed mothers. The high prevalence of maternal postnatal emotional disturbances warrants continual consideration. Higher paternal involvement in childcare arrangements should be emphasized to aid in ameliorating these maternal emotional disturbances, particularly among unemployed mothers.

    The Y1 receptor (Y1R) and Y5 receptor (Y5R) for neuropeptide Y share similar actions in the regulation of anxiety. Previously demonstrated that conditional removal of the Y1R during postnatal development in the forebrain excitatory neurons leads to higher anxiety, increased hypothalamus-pituitary-adrenocortical axis activity, and decreased body growth rate in male mice raised by foster mothers that exhibit high levels of maternal care. In the present study, we used the same conditional system to analyze the specific contribution to emotional behavior and stress response of the Y1R coexpressed with the Y5R. Using the Cre-loxP recombination system, we investigated anxious behavior, spatial memory, and metabolic functions of conditional knockout mice in which the inactivation of the Npy1r gene was induced in the Y5Rs expressing neurons of juvenile mice (Npy1r(Y5R-/-) ). Npy1r(Y5R-/-) mice show increased anxiety-related behavior but no changes in hypothalamus-pituitary-adrenocortical axis activity or in body weight growth, independently of gender and mouse strain used as foster mothers. Also, Npy1r(Y5R-/-) mice of both genders display increased spatial reference memory in the Morris water maze test. The results suggest that neuropeptide Y Y1R differentially expressed in the limbic system regulates anxiety and stress responses via distinct neurochemical circuits. In addition, we provide the first experimental genetic evidence that the Y1Rs coexpressed with the Y5R are involved in retention of spatial memory in male and female mice.

    Many data indicate that endogenous opioid system is involved in amphetamine-induced behavior. Neuropeptide FF (NPFF) possesses opioid-modulating properties. The aim of the present study was to determine whether pharmacological modulation of NPFF receptors modify the expression of amphetamine-induced conditioned place preference (CPP) and amphetamine withdrawal anxiety-like behavior, both processes relevant to drug addiction/abuse. Intracerebroventricular (i.c.v.) injection of NPFF (5, 10, and 20 nmol) inhibited the expression of amphetamine CPP at the doses of 10 and 20 nmol. RF9, the NPFF receptors antagonist, reversed inhibitory effect of NPFF (20 nmol, i.c.v.) at the doses of 10 and 20 nmol and did not show any effect in amphetamine- and saline conditioned rats. Anxiety-like effect of amphetamine withdrawal was measured 24h after the last (14 days) amphetamine (2.5mg/kg, i.p.) treatment in the elevated plus-maze test. Amphetamine withdrawal decreased the percent of time spent by rats in the open arms and the percent of open arms entries. RF9 (5, 10, and 20 nmol, i.c.v.) significantly reversed these anxiety-like effects of amphetamine withdrawal and elevated the percent of time spent by rats in open arms at doses of 5 and 10 nmol, and the percent of open arms entries in all doses used. NPFF (20 nmol) pretreatment inhibited the effect of RF9 (10 nmol). Our results indicated that stimulation or inhibition of NPFF receptors decrease the expression of amphetamine CPP and amphetamine withdrawal anxiety, respectively. These findings may have implications for a better understanding of the processes involved in amphetamine dependence. Copyright © 2011 Elsevier Inc. All rights reserved.

  15. Effect of paternal age in achondroplasia, thanatophoric dysplasia, and osteogenesis imperfecta

    1995-11-06

    The paternal ages of nonfamilial cases of achondroplasia (AC) (n = 78), thanatophoric dysplasia (TD) (n = 64), and osteogenesis imperfecta (OI) (n = 106), were compared with those of matched controls, from an Italian Indagine Policentrica Italiana sulle Malformazioni Congenite (IPIMC) and a South American Estudio Colaborativo Latinoamericano de Malformaciones Congenitas (ECLAMC) series. The degree of paternal age effect on the origin of these dominant mutations differed among the three conditions. Mean paternal age was highly elevated in AC, 36.30 {plus_minus} 6.74 years in the IPIMC, and 37.19 {plus_minus} 10.53 years in the ECLAMC; less consistently elevated in TD, 33.60 {plus_minus} 7.08 years in the IPIMC, and 36.41 {plus_minus} 9.38 years in the ECLAMC; and only slightly elevated in OI in the ECLAMC, 31.15 {plus_minus} 9.25 years, but not in the IPIMC, 32.26 {plus_minus} 6.07 years. Increased maternal age or birth order in these conditions disappeared when corrected for paternal age. Approximately 50% of AC and TD cases, and only 30% of OI cases, were born to fathers above age 35 years. For AC and TD, the increase in relative incidence with paternal age fitted an exponential curve. The variability of paternal age effect in these new mutations could be due, among other reasons, to the high proportion of germ-line mosaicism in OI parents, or to the localization of the AC gene, mapped to the 4p16.3 region, in the neighborhood of an unstable DNA area. 28 refs., 1 fig., 6 tabs.

  16. Examining Differential Resilience Mechanisms by Comparing ‘Tipping Points’ of the Effects of Neighborhood Conditions on Anxiety by Race/Ethnicity

    Full Text Available Exposure to adverse environmental and social conditions affects physical and mental health through complex mechanisms. Different racial/ethnic (R/E groups may be more or less vulnerable to the same conditions, and the resilience mechanisms that can protect them likely operate differently in each population. We investigate how adverse neighborhood conditions (neighborhood disorder, NDis differentially impact mental health (anxiety, Anx in a sample of white and Black (African American young women from Southeast Texas, USA. We illustrate a simple yet underutilized segmented regression model where linearity is relaxed to allow for a shift in the strength of the effect with the levels of the predictor. We compare how these effects change within R/E groups with the level of the predictor, but also how the “tipping points,” where the effects change in strength, may differ by R/E. We find with classic linear regression that neighborhood disorder adversely affects Black women’s anxiety, while in white women the effect seems negligible. Segmented regressions show that the Ndis → Anx effects in both groups of women appear to shift at similar levels, about one-fifth of a standard deviation below the mean of NDis, but the effect for Black women appears to start out as negative, then shifts in sign, i.e., to increase anxiety, while for white women, the opposite pattern emerges. Our findings can aid in devising better strategies for reducing health disparities that take into account different coping or resilience mechanisms operating differentially at distinct levels of adversity. We recommend that researchers investigate when adversity becomes exceedingly harmful and whether this happens differentially in distinct populations, so that intervention policies can be planned to reverse conditions that are more amenable to change, in effect pushing back the overall social risk factors below such tipping points.

    To examine the role of the pair male in ensuring paternity in the wheatear, we removed pair males for 24 h during the fertile period (days 0 to +1 in 1992 and days -5 to -1 in 1993, where day 0=first egg date). Control males were removed during incubation. The frequency and duration of intrusions, and the frequency of extrapair copulations (EPCs), increased during removals in the fertile period, but not during incubation. The frequency of extrapair paternity (EPP) was marginally higher (25%) in experimental than control broods and the presence of the pair male seemed particularly important in ensuring paternity in those days immediately preceding laying. Females were selective over which males they copulated with in the absence of their mate and rejected the majority of attempted EPCs. Only extrapair males in better body condition than the removed pair male eventually gained successful matings. Experimental males in poorer body condition were also more likely to have EPP in their brood than experimental males in better body condition. Female copulatory behaviour was the most important factor in determining patterns of paternity, and mate-guarding behaviours by the pair male appeared to limit the females' opportunities to engage in EPCs by reducing the frequency and duration of intrusions, rather than to control female behaviour directly.

    OBJECTIVE To describe the prevalence of maternity and paternity among subjects and its association with perinatal, socioeconomic and demographic variables. METHODS The participants were youth, aged 23, on the average, accompanied in a cohort study since they were born, in 1982, in Pelotas (Southern Brazil) and interviewed in 2004-5. Those who were considered eligible referred having had one or more children, whether these were liveborns or stillborns. Data was collected on reproductive health as well as socioeconomic and demographic information, by means of two different instruments. The independent variables were sex and skin color, family income in 1982 and in 2004-5, changes in income, birth weight and educational level when aged 23 years old. Crude and adjusted analysis were conducted by means of Poisson regression so as to investigate the effects of the independent variables on maternity/paternity during adolescence. RESULTS Among the 4,297 youth interviewed, 1,373 (32%) were parents and 842 (19.6%) of these had experienced maternity/paternity during their adolescence. Planned pregnancy of the first child was directly related to the youth’s age. Socioeconomic variables were inversely related to the occurrence of maternity/paternity during adolescence. The probability of being an adolescent mother was higher among black and mixed skin colored women, but skin color was not associated to adolescent paternity. CONCLUSIONS There was a strong relation between adolescent maternity/paternity and socioeconomic conditions, which should be taken into consideration when delineating preventive actions in the field of public health.

    There is ongoing debate about the efficacy of placebos in the treatment of mental disorders. In randomized control trials (RCTs) about the treatment of generalized anxiety disorder, the administration of a psychological placebo or placement on a waiting list are the two most common control conditions. But there has never been a systematic comparison of the clinical effect of these different strategies. Compare the change in symptom severity among individuals treated with cognitive behavioral therapy, provided a psychological placebo, or placed on a waiting list using data from RCTs on generalized anxiety disorder. The following databases were searched for RCTs on generalized anxiety disorder: PubMed, PsycInfo, EMBASE, The Cochrane Library, CNKI, Chongqing VIP, Wanfang, Chinese Biological Medical Literature Database, and Taiwan Electronic Periodical Services. Studies were selected based on pre-defined inclusion and exclusion criteria and the quality of each included study - based on the risk of bias and the level of evidence - was formally assessed. Meta-analysis was conducted using RevMan5.3 and network meta-analyses comparing the three groups were conducted using R. Twelve studies with a combined sample size of 531 were included in the analysis. Compared to either control method (placebo or waiting list), cognitive behavioral therapy was more effective for generalized anxiety disorder. Provision of a psychological placebo was associated with a significantly greater reduction of symptoms than placement on a waiting list. Eight of the studies were classified as 'high risk of bias', and the overall level of evidence was classified as 'moderate', indicating that further research could change the overall results of the meta-analysis. RCTs about the treatment of generalized anxiety disorders are generally of moderate quality; they indicate the superiority of CBT but the results cannot, as yet, be considered robust. There is evidence of a non-negligible treatment effect

    Advanced paternal age (APA) at conception has been associated with negative outcomes in offspring, raising concerns about increasing age at fatherhood. Evidence from evolutionary and psychological research, however, suggests possible link between APA and a phenotypic advantage. We defined such advantage as educational success, which is positively associated with future socioeconomic status. We hypothesised that high IQ, strong focus on the subject of interest and little concern about 'fitting in' will be associated with such success. Although these traits are continuously distributed in the population, they cluster together in so-called 'geeks'. We used these measures to compute a 'geek index' (GI), and showed it to be strongly predictive of future academic attainment, beyond the independent contribution of the individual traits. GI was associated with paternal age in male offspring only, and mediated the positive effects of APA on education outcomes, in a similar sexually dimorphic manner. The association between paternal age and GI was partly mediated by genetic factors not correlated with age at fatherhood, suggesting contribution of de novo factors to the 'geeky' phenotype. Our study sheds new light on the multifaceted nature of the APA effects and explores the intricate links between APA, autism and talent.

    The sacred texts of five world religions (Buddhism, Christianity, Hinduism, Islam, and Judaism) use similar belief systems to set limits on sexual behavior. We propose that this similarity is a shared cultural solution to a biological problem: namely male uncertainty over the paternity of offspring. Furthermore, we propose the hypothesis that religious practices that more strongly regulate female sexuality should be more successful at promoting paternity certainty. Using genetic data on 1,706 father–son pairs, we tested this hypothesis in a traditional African population in which multiple religions (Islam, Christianity, and indigenous) coexist in the same families and villages. We show that the indigenous religion enables males to achieve a significantly (P = 0.019) lower probability of cuckoldry (1.3% versus 2.9%) by enforcing the honest signaling of menstruation, but that all three religions share tenets aimed at the avoidance of extrapair copulation. Our findings provide evidence for high paternity certainty in a traditional African population, and they shed light on the reproductive agendas that underlie religious patriarchy. PMID:22665788

  4. Can an experience of a punishment episode in childhood period be connected with depressive or anxiety conditions in adulthood?

    Full Text Available Punishment, when understood as parents' response to undesirable behavior of a child and representing gradual restricting of such behavior, is an essential part of parents' role in the family. In the context of the paradigm of affective regulation, anxiety and depression states represent another unsuccessful attempt of trying to get closer and to find a connection in the relationship. This study, conducted on 197 participants, addressed the connection between punishment in upbringing and behavior disturbances in adulthood. Depressive states in adulthood were statistically significantly, although weakly connected with the experience of corporal punishment, punishment and restitution, and psychological aggression form both parents. Anxiety states were statistically significantly, although weakly connected with the experience of psychological aggression from both parents and with the experience of corporal punishment, and punishment and restitution of the mother. The participants who attained the criteria for diagnosis of depression were more exposed to corporal punishment at the age of 10 years (from both parents, punishment and restitution (from the father and psychological aggression (from the father compared to the participants without the diagnosis of depression. The paradigm of affective regulation is presented as a possible explanation of the connection between experiences of punishment as a way of upbringing in childhood and later mood disorders in adulthood. Punishment during upbringing that is not accompanied by parents' maintaining of the connection with the child can present the first experience of negative affection, which is the core of anxiety and depressive states. The mood disorders in adulthood can be understood as another failure when trying to reestablish the balance between external information and internal experiences that were primarily disturbed by the experience of punishment when growing up.

    To assess the prevalence and clinical impact of co-morbid social anxiety disorder (SAD) and alcohol use disorders (AUD, i.e. alcohol abuse and alcohol dependence) in a nationally representative sample of adults in the United States. Data came from a large representative sample of the US population. Face-to-face interviews of 43093 adults residing in households were conducted during 2001-2002. Diagnoses of mood, anxiety, alcohol and drug use disorders and personality disorders were based on the Alcohol Use Disorder and Associated Disabilities Interview Schedule - DSM-IV version. Lifetime prevalence of co-morbid AUD and SAD in the general population was 2.4%. SAD was associated with significantly increased rates of alcohol dependence [odds ratio (OR) 2.8] and alcohol abuse (OR 1.2). Among respondents with alcohol dependence, SAD was associated with significantly more mood, anxiety, psychotic and personality disorders. Among respondents with SAD, alcohol dependence and abuse were most strongly associated with more substance use disorders, pathological gambling and antisocial personality disorders. SAD occurred before alcohol dependence in 79.7% of co-morbid cases, but co-morbidity status did not influence age of onset for either disorder. Co-morbid SAD was associated with increased severity of alcohol dependence and abuse. Respondents with co-morbid SAD and alcohol dependence or abuse reported low rates of treatment-seeking. Co-morbid lifetime AUD and SAD is a prevalent dual diagnosis, associated with substantial rates of additional co-morbidity, but remaining largely untreated. Future research should clarify the etiology of this co-morbid presentation to better identify effective means of intervention.

  6. Paternity acknowledgment in 2 million birth records from Michigan.

    Directory of Open Access Journals (Sweden)

    Douglas Almond

    Full Text Available Out-of-wedlock childbearing is more common in the U.S. than in other countries and becoming more so. A growing share of such non-marital births identify the father, which can create a legal entitlement to child support. Relatively little is known about individual determinants of the decision to establish paternity, in part because of data limitations. In this paper, we evaluate all birth records in Michigan from 1993 to 2006, which have been merged to the paternity registry. In 2006, 30,231 Michigan children, almost one quarter of all Michigan births, were born to unmarried mothers and had paternity acknowledged. We find that births with paternity acknowledged have worse outcomes along various health and socio-economic dimensions relative to births to married parents, but better outcomes relative to births to unmarried parents without paternity acknowledgement. Furthermore, unmarried men who father sons are significantly more likely to acknowledge paternity than fathers of daughters.

  7. A defence of medical paternalism: maximising patients' autonomy.

    OpenAIRE

    1983-01-01

    All illness represents a state of diminished autonomy and therefore the doctor-patient relationship necessarily and justifiably involves a degree of medical paternalism argues the author, an American medical student. In a broad-ranging paper he discusses the concepts of autonomy and paternalism in the context of the doctor-patient relationship. Given the necessary diminution of autonomy which illness inflicts, a limited form of medical paternalism, aimed at restoring or maximising the patient...

    A 29-year-old primigravida developed polyhydramnios at 24 weeks of gestation, requiring six serial amnioreductions. In addition, prenatal ultrasound examinations revealed a fetus with small stomach pouch, small thorax, slightly shortened limbs, and skin edema; paternal uniparental disomy 14(upd(14)pat) phenotype was suspected. At 37 weeks, the patient delivered a 2558 g female infant with characteristic facial features, webbed neck, thoracic deformity, abdominal wall defect, skin edema, overlapping fingers, placentomegaly, and small thorax with 'coat-hanger' appearance of the ribs on chest X-ray. A phenotype consistent with upd(14)pat was confirmed by DNA analysis. Although the infant's condition was initially stable, hepatoblastoma was subsequently detected and right hepatectomy was performed on day 224. On day 382, the infant was discharged with in-home respiratory management. © 2012 The Authors. Congenital Anomalies © 2012 Japanese Teratology Society.

  9. Was bioethics founded on historical and conceptual mistakes about medical paternalism?

    Science.gov (United States)

    McCullough, Laurence B

    2011-02-01

    Bioethics has a founding story in which medical paternalism, the interference with the autonomy of patients for their own clinical benefit, was an accepted ethical norm in the history of Western medical ethics and was widespread in clinical practice until bioethics changed the ethical norms and practice of medicine. In this paper I show that the founding story of bioethics misreads major texts in the history of Western medical ethics. I also show that a major source for empirical claims about the widespread practice of medical paternalism has been misread. I then show that that bioethics based on its founding story deprofessionalizes medical ethics. The result leaves the sick exposed to the predatory power of medical practitioners and healthcare organizations with only their autonomy-based rights to non-interference, expressed in contracts, to protect them. The sick are stripped of the protection afforded by a professional, fiduciary relationship of physicians to their patients. Bioethics based on its founding story reverts to the older model of a contractual relationship between the sick and medical practitioners not worthy of intellectual or moral trust (because such trust cannot be generated by what I call 'deprofessionalizing bioethics'). On closer examination, bioethics based on its founding story, ironically, eliminates paternalism as a moral category in bioethics, thus causing bioethics to collapse on itself because it denies one of the necessary conditions for medical paternalism. Bioethics based on its founding story should be abandoned. © 2010 Blackwell Publishing Ltd.

    Cannabis use disorders (CUD) are highly comorbid with social anxiety disorder (SAD), and SAD may be a risk factor for cannabis dependence. This study explored these relationships in several ways. First, we examined whether SAD was more likely to be related to cannabis dependence than abuse. Second, we examined the temporal relations between CUD and SAD. Third, we examined whether SAD was related to faster transition from age of first cannabis use to CUD onset relative to other anxiety disorders. Fourth, we tested whether having both disorders was associated with greater impairment and psychiatric comorbidity. The sample consisted of adults from Wave 1 of the National Epidemiological Survey on Alcohol and Related Conditions, 2957 of whom had CUD and no SAD, 1643 had SAD and no CUD, and 340 had CUD-SAD. SAD was more likely to be related to cannabis dependence than abuse. This relation remained after controlling for race, sex, and some other psychiatric disorders (including some anxiety disorders). Age-of-onset data suggest SAD onset prior to CUD onset for most CUD-SAD respondents. CUD-SAD was related to greater impairment and psychiatric comorbidity than either disorder alone. Although SAD is related to CUD, it has a stronger association with cannabis dependence than abuse. This link is not better accounted for by other psychopathology measured in this study. SAD onset prior to CUD for the majority of CUD-SAD respondents. Importantly, the co-occurrence of these two disorders appears to result in greater impairment and distress than either disorder alone.

  11. Fertility assurance through extrapair fertilizations and male paternity defense.

    Science.gov (United States)

    Fishman, Michael A; Stone, Lewi; Lotem, Arnon

    2003-03-07

    Extrapair paternity has been observed in many formally monogamous species. Male pursuit of extrapair fertilizations is explained by the advantages of having offspring that receive essential paternal care from other males. Since females are capable of exercising a degree of control over the post-copulatory sperm competition, extrapair paternity cannot persist unless it confers fitness benefits on cuckolding females. Thus, extrapair paternity involves cooperation between mated females and extrapair males. On the other hand, paired males frequently exhibit strategies that minimize their loss of paternity and/or conserve paternal investment if paternity is lost. Hence, extrapair attributes of diverse species and populations reported in the literature are particular solutions of evolutionary games involving gender-specific cuckolding/anti-cuckolding strategies. Here we use methods of evolutionary game theory to study the role of male paternity guarding strategies in situations where females seek extrapair fertilizations for reasons of genetic compatibility and/or in pursuit of genetic diversity for their offspring. Our results indicate that in these circumstances pursuit of extrapair fertilizations is the only evolutionary stable female strategy. Males, on the other hand, have two, mutually exclusive, evolutionary stable strategies: full time pursuit of extrapair fertilizations and a compromise strategy wherein they protect in-pair paternity during their mate's fertile periods and pursue extrapair paternity the rest of the time. The relative merits of these two strategies are determined by the efficiency of male in-pair paternity defense, breeding synchrony, fitness advantages of extrapair over in-pair offspring, and the intensity of competition for extrapair fertilizations from floater males.

  12. Gratitude lessens death anxiety.

    Lau, Rosanna W L; Cheng, Sheung-Tak

    2011-09-01

    This study investigated whether a brief gratitude induction could reduce death anxiety. 83 Chinese older adults (mean age = 62.7, SD = 7.13) were randomly assigned into one of three conditions: gratitude, hassle, and neutral, in which they wrote different types of life events before responding to measures of death anxiety and affect. Participants in the gratitude induction reported lower death anxiety than the hassle and the neutral condition, whereas no difference was observed for the latter two conditions. There was no experimental effect on positive affect, and a significant effect on negative affect but which did not favor the gratitude condition. By reexamining life events with a thankful attitude, people may become less fearful of death due to a sense that life has been well-lived. Because gratitude can be induced using a very brief procedure, there are broad applications in clinical and health-care settings for the relief of death anxiety.

  13. Paternal and sibling incest: a case report.

    Science.gov (United States)

    2006-01-01

    A case is reported of a female victim of paternal incest, who had also been raped repeatedly by her elder brother for two years. A survey of the literature showed no other report of such a case from Turkey. This does not necessarily mean that the incidence of paternal and sibling incest does not happen, but may indicate that incestuous abuse is not reported or handled without making it known to legal authorities. The victim was first raped by her 16 year-old brother when she was 9 years old. He raped her repeatedly over a period of two years, until he left home. Her father began raping the victim when she was 13 year-old, leaving her pregnant at age 15. He took her to a doctor for a termination of pregnancy. The father continued abuse after the termination. The victim left home to marry a man. The father filed a lawsuit against the man for taking the victim away from home. More openness and awareness of incest in Turkey may encourage the victims to seek help from medical and legal authorities.

    Decapod crustaceans exhibit considerable variation in fertilisation strategies, ranging from pervasive single paternity to the near-ubiquitous presence of multiple paternity, and such knowledge of mating systems and behaviour are required for the informed management of commercially-exploited marine fisheries. We used genetic markers to assess the paternity of individual broods in the European lobster, Homarus gammarus, a species for which paternity structure is unknown. Using 13 multiplexed microsatellite loci, three of which are newly described in this study, we genotyped 10 eggs from each of 34 females collected from an Atlantic peninsula in the south-western United Kingdom. Single reconstructed paternal genotypes explained all observed progeny genotypes in each of the 34 egg clutches, and each clutch was fertilised by a different male. Simulations indicated that the probability of detecting multiple paternity was in excess of 95% if secondary sires account for at least a quarter of the brood, and in excess of 99% where additional sire success was approximately equal. Our results show that multiple paternal fertilisations are either absent, unusual, or highly skewed in favour of a single male among H. gammarus in this area. Potential mechanisms upholding single paternal fertilisation are discussed, along with the prospective utility of parentage assignments in evaluations of hatchery stocking and other fishery conservation approaches in light of this finding.

I also suggest that…

  2. Relationships of maternal and paternal anthropometry with neonatal body size, proportions and adiposity in an Australian cohort.

    2015-04-01

    The patterns of association between maternal or paternal and neonatal phenotype may offer insight into how neonatal characteristics are shaped by evolutionary processes, such as conflicting parental interests in fetal investment and obstetric constraints. Paternal interests are theoretically served by maximizing fetal growth, and maternal interests by managing investment in current and future offspring, but whether paternal and maternal influences act on different components of overall size is unknown. We tested whether parents' prepregnancy height and body mass index (BMI) were related to neonatal anthropometry (birthweight, head circumference, absolute and proportional limb segment and trunk lengths, subcutaneous fat) among 1,041 Australian neonates using stepwise linear regression. Maternal and paternal height and maternal BMI were associated with birthweight. Paternal height related to offspring forearm and lower leg lengths, maternal height and BMI to neonatal head circumference, and maternal BMI to offspring adiposity. Principal components analysis identified three components of variability reflecting neonatal "head and trunk skeletal size," "adiposity," and "limb lengths." Regression analyses of the component scores supported the associations of head and trunk size or adiposity with maternal anthropometry, and limb lengths with paternal anthropometry. Our results suggest that while neonatal fatness reflects environmental conditions (maternal physiology), head circumference and limb and trunk lengths show differing associations with parental anthropometry. These patterns may reflect genetics, parental imprinting and environmental influences in a manner consistent with parental conflicts of interest. Paternal height may relate to neonatal limb length as a means of increasing fetal growth without exacerbating the risk of obstetric complications. © 2014 The Authors American Journal of Physical Anthropology Published by Wiley Periodicals, Inc.

    Publications that describe the composition of the human Y-DNA haplogroup in diffferent ethnic or linguistic groups and geographic regions provide no explicit explanation of the distribution of human paternal lineages in relation to specific ecological conditions. Our research attempts to address this topic for the Caucasus, a geographic region that encompasses a relatively small area but harbors high linguistic, ethnic, and Y-DNA haplogroup diversity. We genotyped 224 men that identified themselves as ethnic Georgian for 23 Y-chromosome short tandem-repeat markers and assigned them to their geographic places of origin. The genotyped data were supplemented with published data on haplogroup composition and location of other ethnic groups of the Caucasus. We used multivariate statistical methods to see if linguistics, climate, and landscape accounted for geographical diffferences in frequencies of the Y-DNA haplogroups G2, R1a, R1b, J1, and J2. The analysis showed significant associations of (1) G2 with wellforested mountains, (2) J2 with warm areas or poorly forested mountains, and (3) J1 with poorly forested mountains. R1b showed no association with environment. Haplogroups J1 and R1a were significantly associated with Daghestanian and Kipchak speakers, respectively, but the other haplogroups showed no such simple associations with languages. Climate and landscape in the context of competition over productive areas among diffferent paternal lineages, arriving in the Caucasus in diffferent times, have played an important role in shaping the present-day spatial distribution of patrilineages in the Caucasus. This spatial pattern had formed before linguistic subdivisions were finally shaped, probably in the Neolithic to Bronze Age. Later historical turmoil had little influence on the patrilineage composition and spatial distribution. Based on our results, the scenario of postglacial expansions of humans and their languages to the Caucasus from the Middle East, western

    Advanced paternal age at childbirth is associated with psychiatric disorders in offspring, including schizophrenia, bipolar disorder and autism. However, few studies have investigated paternal age's relationship with eating disorders in offspring. In a large, population-based cohort, we examined the association between paternal age and offspring eating disorders, and whether that association remains after adjustment for potential confounders (e.g. parental education level) that may be related to late/early selection into fatherhood and to eating disorder incidence. Data for 2 276 809 individuals born in Sweden 1979-2001 were extracted from Swedish population and healthcare registers. The authors used Cox proportional hazards models to examine the effect of paternal age on the first incidence of healthcare-recorded anorexia nervosa (AN) and all eating disorders (AED) occurring 1987-2009. Models were adjusted for sex, birth order, maternal age at childbirth, and maternal and paternal covariates including country of birth, highest education level, and lifetime psychiatric and criminal history. Even after adjustment for covariates including maternal age, advanced paternal age was associated with increased risk, and younger paternal age with decreased risk, of AN and AED. For example, the fully adjusted hazard ratio for the 45+ years (v. the 25-29 years) paternal age category was 1.32 [95% confidence interval (CI) 1.14-1.53] for AN and 1.26 (95% CI 1.13-1.40) for AED. In this large, population-based cohort, paternal age at childbirth was positively associated with eating disorders in offspring, even after adjustment for potential confounders. Future research should further explore potential explanations for the association, including de novo mutations in the paternal germline.

  8. Role of NPY Y1 receptor on acquisition, consolidation and extinction on contextual fear conditioning: dissociation between anxiety, locomotion and non-emotional memory behavior.

    Lach, Gilliard; de Lima, Thereza Christina Monteiro

    2013-07-01

    Neuropeptide Y (NPY) is the most abundant peptide in the central nervous system (CNS) and is densely localized in the brain regions involved in stress, memory, fear and anxiety. Although previous research supports a role for NPY in the mediation of rodent and human emotional behavior, there is currently a lack of information on the effects of low doses of NPY that could have a potential therapeutic advantage, minimizing side-effects such as cognition impairment or sedation. Herein, we assessed the effects of intracerebroventricular (i.c.v.) administration of low doses of NPY, and of the Y1-agonist Leu31Pro34-NPY (LP-NPY) on contextual fear conditioning (CFC), as they have no effect on unconditioned anxiety-like, locomotor activity and non-emotional memory. NPY (3 pmol) and LP-NPY (1 pmol) inhibited freezing behavior when administered in the acquisition or consolidation stages, indicating a reduction of fear. When injected in the extinction phase, only NPY inhibited freezing behavior on CFC. Pre-treatment with the Y1-antagonist BIBO3304 before NPY and LP-NPY was able to prevent the inhibition of fear responses induced by both NPY agonists. Taken together, our results demonstrate robust fear-inhibiting effects of i.c.v. injection of NPY on contextual fear conditioning in rats, a response that is mediated, at least in part, by the Y1 receptor. Moreover, these treatments were unable to change locomotor activity or to show an anxiolytic-like effect, as evaluated in an open-field and an elevated plus-maze. This specific fear reduction effect may underlie resilience systems in the CNS and has potential therapeutic relevance in PTSD. Copyright © 2013 Elsevier Inc. All rights reserved.

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

    2006-01-01

    MICROSATELLITE ANALYSIS: By using serological or HLA-testing, the alleged father can be excluded as the biological father, but, regardless of the degree of probability, positive paternity results cannot be obtained without DNA testing. According to the results of the National Human Genome Project, human genome consists of approximately 30.000 genes. The vast majority of human DNA is not organized in genes and has no genetic expression or visible function. Non-coding DNA contains genetic markers important for human identification. Short tandem repeats, or STRs, are a class of microsatellites consisting of tandemly repeated sequences of 2 to 6 base pair length monomers. Most of the microsatellites show a high degree of polymorphism, which can be evaluated by PCR technique, and used in criminalistics, forensic identification and parentage testing. A source of DNA in parentage testing are blood samples or buccal swabs which are routinelly used. Amplification of isolated DNA can be performed in 25-30 cycles by PCR, and fragments are separated by capillary electrophoresis. The probability of paternity of 99.99% or higher corresponds to the paternity "practically proven", indicating that the alleged father is the biological father. Such results can be obtained only by DNA testing. DNA-testing laboratories are required to conduct validation of laboratory facilities, equipment and staff and are subject to permanent control by the society.

    Reproductive strategy is a central feature of the ecology of invasive species as it determines the potential for population increase and range expansion. The red swamp crayfish, Procambarus clarkii, has invaded many countries and caused serious problems in freshwater ecosystems. However, little is known about the effects of environmental conditions on crayfish paternity and offspring traits in the wild. We studied these reproductive characteristics of P. clarkii in wild populations from two different habitats (ponds and ditches) in three locations with different environmental conditions in China. Genotyping of 1,436 offspring and 30 mothers of 30 broods was conducted by using four microsatellites. An analysis of genotyping results revealed that gravid females were the exclusive mother of the progeny they tended. Twenty-nine of 30 mothers had mated with multiple (2-4) males, each of which contributed differently to the number of offspring in a brood. The average number of fathers per brood and the number of offspring per brood were similar (P > 0.05) among six sampling sites, indicating that in P. clarkii multiple paternity and offspring number per brood are independent of environmental conditions studied. Indirect benefits from increasing the genetic diversity of broods, male and sperm competition, and cryptic female choice are a possible explanation for the high level multiple paternity and different contribution of fathers to offspring in this species.

    Full Text Available DNA polymorphism is very useful in paternity analysis. The present paper describes paternity studies done using DNA profiles obtained with the (CAC5 probe. All of the subjects studied were involved in nonjudicial cases of paternity. Genomic DNA digested with HaeIII was run on agarose gels and hybridized in the gel with the (CAC5 probe labeled with 32P. The mean number of bands larger than the 4.3 kb per individual was 16.1. The mean proportion of bands shared among unrelated individuals was 0.08 and the mean number of test bands was 7.1. This corresponded to an exclusion probability greater than 0.999999. Paternity was excluded in 34.5% of the cases. The mutation frequency estimated from non-excluded cases was 0.01143 bands per child. In these cases, the paternity was confirmed by a locus-specific analysis of eight independent PCR-based loci. The paternity index was computed in all non-excluded cases. It can be concluded that this method is a powerful and inexpensive alternative to solve paternity doubts.

    Social anxiety is the most common anxiety disorder among youth; theoretical and empirical work suggest specific parenting behaviors may be relevant. However, findings are inconsistent, particularly in terms of maternal as compared to paternal effects. In the current study, we evaluated the indirect effects of perceived psychological control on the relation between anxious rearing behaviors and child social anxiety among 112 community-recruited girls (ages 12-15 years). In addition to self-report, adolescent participants completed a laboratory-based social stress task. In line with hypotheses, results indicated indirect effects of psychological control on the relation between anxious rearing behaviors and child social anxiety in maternal but not paternal models. Findings are discussed in terms of their theoretical and empirical implications for clarifying the role of parental relations in adolescent social anxiety.

    To study mitochondrial–nuclear genetic interactions in the nematode Caenorhabditis briggsae, our three laboratories independently created 38 intra-species cytoplasmic–nuclear hybrid (cybrid) lines. Although the cross design combines maternal mitotypes with paternal nuclear genotypes, eight lines (21%) unexpectedly contained paternal mitotypes. All eight share in common ancestry of one of two genetically related strains. This unexpected parallel observation of paternal mitochondrial transmission, undesirable given our intent of creating cybrids, provides a serendipitous experimental model and framework to study the molecular and evolutionary basis of uniparental mitochondrial inheritance.

    Full Text Available The neo-classical principles of rational behavior are considered in the context of the nature of paternalism as the basis of the Theory of patronized goods. The formation of society’s normative interests is discussed in concern of political aspects. The article illustrates the theoretical and the practical aspects of the concept of consociation democracy, providing liberalization of the institutions for making political and economic decisions. The results of analysis reveal a pattern of paternalism drifting towards institutional liberalization. Proposed a hypothesis explaining why the economic policy in modern Russia still remains somewhere between archaic and merit paternalism.

  18. Conditioned odor aversion induces social anxiety towards females in wild-type and TrpC2 knockout male mice.

    Female-emitted pheromonal inputs possess an intrinsic rewarding value for conspecific males, promoting approach and investigation of the potential mating partner. In mice these inputs are detected mainly by the vomeronasal organ (VNO) and the main olfactory epithelium (MOE). We investigated the role of VNO-mediated inputs in experience-dependent plasticity of reproductive responses. We applied a sex-specific conditioned odor aversion (COA) paradigm on adult, wild-type (WT) male mice and on male mice impaired in VNO-mediated signal transduction (TrpC2 -/- ). We found that WT males, which underwent COA to female-soiled bedding, lost their innate preference to female odors and presented lower motivation to approach a sexually receptive female. COA also abolished the testosterone surge normally seen following exposure to female odors. Moreover, the conditioned males displayed impairments in copulatory behaviors, which lasted for several weeks. Surprisingly, these males also exhibited phobic behaviors towards receptive females, including freezing and fleeing responses. In contrast, WT males which underwent COA specifically to male pheromones showed no change in olfactory preference and only a marginally significant elevation in intermale aggression. Finally, we show that TrpC2 -/- males were able to acquire aversion to female-soiled bedding and presented similar behavioral alterations following COA in their responses to female cues. Our results demonstrate that the intrinsic rewarding value of female pheromones can be overridden through associative olfactory learning, which occurs independently of VNO inputs, probably through MOE signaling. © 2016 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

    Early – intrauterine – environmental factors are linked to the development of cardiovascular disease in later life. Traditionally, these factors are considered to be maternal factors such as maternal under and overnutrition, exposure to toxins, lack of micronutrients, and stress during pregnancy. However, in the recent years, it became obvious that also paternal environmental factors before conception and during sperm development determine the health of the offspring in later life. We will first describe clinical observational studies providing evidence for paternal programming of adulthood diseases in progeny. Next, we describe key animal studies proving this relationship, followed by a detailed analysis of our current understanding of the underlying molecular mechanisms of paternal programming. Alterations of noncoding sperm micro-RNAs, histone acetylation, and targeted as well as global DNA methylation seem to be in particular involved in paternal programming of offspring's diseases in later life.

    2009-01-01

    Most socially monogamous bird species engage in extra-pair mating, and consequently males may adopt various behavioral strategies to guard paternity. However, the relationship between mate guarding and extra-pair paternity is unclear: low levels of extra-pair paternity can be associated either with no mate guarding or with intense mate guarding. We investigate paternity guards in the purple-crowned fairy-wren (Malurus coronatus), a duetting species where extra-pair paternity is rare. This spe...

  1. Paternal and maternal transition to parenthood: the risk of postpartum depression and parenting stress

    Full Text Available Transition to parenthood represents an important life event increasing vulnerability to psychological disorders. Postpartum depression and parenting distress are the most common psychological disturbances and a growing scientific evidence suggests that both mothers and fathers are involved in this developmental crisis. This paper aims to explore maternal and paternal experience of transition to parenthood in terms of parenting distress and risk of postpartum depression. Seventy-five couples of first-time parents were invited to compile the Edinburgh Postnatal Depression Scale and the Parenting Stress Index-Short Form in the first month of children life. Study sample reported very high levels of parenting distress and a risk of postpartum depression in 20.8% of mothers and 5.7% of fathers. No significant correlation between parenting distress and the risk of postpartum depression emerged, both in mothers than in fathers group while maternal distress levels are related to paternal one. The first month after partum represents a critical phase of parents life and it could be considered a developmental crisis characterized by anxiety, stress and mood alterations that could have important repercussions on the child psycho-physical development.

    2000-01-01

    Studies of several bird species have shown that coloured leg bands may affect a male's success in mate attraction and/or mating competition. From a colour band experiment in the field, we have previously reported that male bluethroats, Luscinia s. svecica, with blue and orange bands (BO males) guarded their mates less intensely at the peak of female fertility, and spent more time advertising for additional mates, than males banded with non-BO colours. These responses indicated that BO males experienced less threat to their paternity than did non-BO males, possibly mediated through an increased attractiveness. Here we present paternity analyses of the broods from the field study and test whether there were differences between the two male groups in within-pair or extrapair paternity. There were no significant differences between the two groups of males in paternity, suggesting effective male protection of paternity. However, extrapair paternity was infrequent in the 2 years of the field experiment; hence, the power in detecting effects on paternity does not allow a definitive conclusion on this issue. We also conducted an aviary experiment in which females were given the choice between a BO male and a non-BO male, to test whether females had preferences for particular colour bands. Females did not associate more with BO males, as would have been expected if these males were more attractive in social mate choice. Our results suggest that the effects of colour bands on social mate choice and paternity are, at best, weak. Copyright 2000 The Association for the Study of Animal Behaviour.

    Research indicates that parental divorce and parental alcohol abuse independently increase likelihood of offspring lifetime suicide attempt. However, when experienced together, only parental alcohol abuse significantly increased odds of suicide attempt. It is unclear to what extent differences in the effect of maternal versus paternal alcohol use exist on adult offspring lifetime suicide attempt risk. This study examined the influences of parental divorce and maternal-paternal histories of alcohol problems on adult offspring lifetime suicide attempt. The sample consisted of participants from the 2001-2002 National Epidemiological Survey on Alcohol and Related Conditions. The simultaneous effect of childhood or adolescent parental divorce and maternal and paternal history of alcohol problems on offspring lifetime suicide attempt was estimated using a logistic regression model with an interaction term for demographics and parental history of other emotional and behavioural problems. Parental divorce and maternal-paternal alcohol problems interacted to differentially influence the likelihood of offspring lifetime suicide attempt. Experiencing parental divorce and either maternal or paternal alcohol problems nearly doubled the likelihood of suicide attempt. Divorce and history of alcohol problems for both parents tripled the likelihood. Individuals who experienced parental divorce as children or adolescents and who have a parent who abuses alcohol are at elevated risk for lifetime suicide attempt. These problem areas should become a routine part of assessment to better identify those at risk for lifetime suicide attempt and to implement early and targeted intervention to decrease such risk.

    The up-to-date prevention and management of anxiety states in childhood is discussed with particular reference to the different presentations of anxiety and the ways in which preventive measures may be used. Anxiety creating developmental lag, mimicking other conditions, and appearing in very specific forms is mentioned. Techniques for handling are introduced together with some suggestions on the responsibility of the family doctor in this whole area of psychological medicine. In this article, the child is seen as part of a family setting; the effect of disturbances in the family constellation resulting in anxiety for the child is described. Some suggestions for ways in which the physician may be involved in patient and parent education are put forward. PMID:21301539

    Prior research indicates that infants with absent fathers are vulnerable to unfavorable fetal birth outcomes. HIV is a recognized risk factor for adverse birth outcomes. However, the influence of paternal involvement on fetal morbidity outcomes in women with HIV remains poorly understood. Using linked hospital discharge data and vital statistics records for the state of Florida (1998-2007), the authors assessed the association between paternal involvement and fetal growth outcomes (i.e., low birth weight [LBW], very low birth weight [VLBW], preterm birth [PTB], very preterm birth [VPTB], and small for gestational age [SGA]) among HIV-positive mothers (N=4,719). Propensity score matching was used to match cases (absent fathers) to controls (fathers involved). Conditional logistic regression was employed to generate adjusted odds ratios (OR). Mothers of infants with absent fathers were more likely to be Black, younger (outcomes (LBW: OR=1.30, 95% confidence interval [CI]=1.05-1.60; VLBW: OR=1.72, 95% CI=1.05-2.82; PTB: OR=1.38, 95% CI=1.13-1.69; VPTB: OR=1.81, 95% CI=1.13-2.90). Absence of fathers increases the likelihood of adverse fetal morbidity outcomes in women with HIV infection. These findings underscore the importance of paternal involvement during pregnancy, especially as an important component of programs for prevention of mother-to-child transmission of HIV. © The Author(s) 2013.

    Some forms of epigenetic abnormalities transmitted to offspring are manifested in differences in disease incidence that depend on parent-of-origin. To explore whether such phenomena might operate in schizophrenia spectrum disorders, we estimated the relative incidence of these conditions in relation to parent-of-origin by considering the two grandfathers' countries of birth. In a prospective cohort of 88,829 offspring, born in Jerusalem in 1964-76 we identified 637 cases through Israel's psychiatric registry. Relative risks (RR) were estimated for paternal and maternal grandfathers' countries of birth using proportional hazards methods, controlling for parents' ages, low social class and duration of marriage. After adjusting for multiple observations, we found no significant differences between descendants of maternal or paternal grandfathers born in Iraq, Iran, Turkey, Syria, Yemen, Morocco, Algeria, Tunisia, Libya/Egypt, Poland, USSR, Czechoslovakia, Germany or the USA. Those with paternal grandfathers from Romania (RR=1.9, 95% CI=1.3-2.8) or Hungary (1.6, 1.0-2.6) showed an increased incidence; however, those with maternal grandfathers from these countries experienced reduced incidence (RR=0.5, 0.3-0.8 and 0.4, 0.2-0.8). In post-hoc analyses we found that results were similar whether the comparison groups were restricted to descendants of other Europeans or included those from Western Asia and North Africa; and effects of paternal grandfathers from Romania/Hungary were more pronounced in females, while effects of maternal grandfathers from these countries were similar in males and females. These post-hoc "hypothesis-generating" findings lead one to question whether some families with ancestors in Romania or Hungary might carry a variant or mutation at a parentally imprinted locus that is altering susceptibility to schizophrenia. Such a locus, if it exists, might involve the X chromosome.

    Anxiety after stroke is common and disabling. Stroke trialists have treated anxiety as a homogenous condition, and intervention studies have followed suit, neglecting the different treatment approaches for phobic and generalized anxiety. Using diagnostic psychiatric interviews, we aimed to report the frequency of phobic and generalized anxiety, phobic avoidance, predictors of anxiety, and patient outcomes at 3 months poststroke/transient ischemic attack. We followed prospectively a cohort of new diagnosis of stroke/transient ischemic attack at 3 months with a telephone semistructured psychiatric interview, Fear Questionnaire, modified Rankin Scale, EuroQol-5D5L, and Work and Social Adjustment Scale. Anxiety disorder was common (any anxiety disorder, 38 of 175 [22%]). Phobic disorder was the predominant anxiety subtype: phobic disorder only, 18 of 175 (10%); phobic and generalized anxiety disorder, 13 of 175 (7%); and generalized anxiety disorder only, 7 of 175 (4%). Participants with anxiety disorder reported higher level of phobic avoidance across all situations on the Fear Questionnaire. Younger age (per decade increase in odds ratio, 0.64; 95% confidence interval, 0.45-0.91) and having previous anxiety/depression (odds ratio, 4.38; 95% confidence interval, 1.94-9.89) were predictors for anxiety poststroke/transient ischemic attack. Participants with anxiety disorder were more dependent (modified Rankin Scale score 3-5, [anxiety] 55% versus [no anxiety] 29%; P anxiety] 19.5, 10-27 versus [no anxiety] 0, 0-5; P Anxiety after stroke/transient ischemic attack is predominantly phobic and is associated with poorer patient outcomes. Trials of anxiety intervention in stroke should consider the different treatment approaches needed for phobic and generalized anxiety. © 2018 The Authors.

    It is well known that advancing paternal age is associated with an increased risk of schizophrenia in offspring, but the mechanism behind this association remains unknown. This study investigates if delayed fatherhood rather than advancing paternal age per se might explain the increased risk of schizophrenia in offspring associated with advancing paternal age. This is a register-based study of the Swedish population looking at people born 1955-1985 who have 1 or 2 siblings (n = 2 589 502). The main analysis investigated whether the association between advancing paternal age and schizophrenia was explained by delayed fatherhood. Possible confounding factors were taken into account. Cox regression was used throughout. In the main analysis the association between advancing paternal age and increased risk of schizophrenia in offspring disappeared after controlling for delayed fatherhood (hazard ratio [HR] = 0.93, 95% CI = 0.72-1.21 comparing 45+ years old fathers to those 25-29), whereas delayed fatherhood showed an association with increased risk of schizophrenia in offspring comparing 35-39 and 40-44 years old fathers to 25-29 year olds (HR = 1.37, 95% CI = 1.18-1.58; HR = 1.81, 95% CI = 1.44-2.28, respectively). The results remained when controlling for possible confounders. This study suggests that the association between paternal age and schizophrenia is not due to paternal age per se, but rather to an unknown factor associated with both delayed fatherhood and schizophrenia. © The Author 2014.

  15. Paternal Aging Affects Behavior in Pax6 Mutant Mice: A Gene/Environment Interaction in Understanding Neurodevelopmental Disorders.

    Directory of Open Access Journals (Sweden)

    Kaichi Yoshizaki

    Full Text Available Neurodevelopmental disorders such as autism spectrum disorder (ASD and attention deficit and hyperactivity disorder (ADHD have increased over the last few decades. These neurodevelopmental disorders are characterized by a complex etiology, which involves multiple genes and gene-environmental interactions. Various genes that control specific properties of neural development exert pivotal roles in the occurrence and severity of phenotypes associated with neurodevelopmental disorders. Moreover, paternal aging has been reported as one of the factors that contribute to the risk of ASD and ADHD. Here we report, for the first time, that paternal aging has profound effects on the onset of behavioral abnormalities in mice carrying a mutation of Pax6, a gene with neurodevelopmental regulatory functions. We adopted an in vitro fertilization approach to restrict the influence of additional factors. Comprehensive behavioral analyses were performed in Sey/+ mice (i.e., Pax6 mutant heterozygotes born from in vitro fertilization of sperm taken from young or aged Sey/+ fathers. No body weight changes were found in the four groups, i.e., Sey/+ and wild type (WT mice born to young or aged father. However, we found important differences in maternal separation-induced ultrasonic vocalizations of Sey/+ mice born from young father and in the level of hyperactivity of Sey/+ mice born from aged fathers in the open-field test, respectively, compared to WT littermates. Phenotypes of anxiety were observed in both genotypes born from aged fathers compared with those born from young fathers. No significant difference was found in social behavior and sensorimotor gating among the four groups. These results indicate that mice with a single genetic risk factor can develop different phenotypes depending on the paternal age. Our study advocates for serious considerations on the role of paternal aging in breeding strategies for animal studies.

    The assessment of children's psychopathology is often based on parental report. Earlier studies have suggested that rater bias can affect the estimates of genetic, shared environmental and unique environmental influences on differences between children. The availability of a large dataset of maternal as well as paternal ratings of psychopathology in 7-year old children enabled (i) the analysis of informant effects on these assessments, and (ii) to obtain more reliable estimates of the genetic and non-genetic effects. DSM-oriented measures of affective, anxiety, somatic, attention-deficit/hyperactivity, oppositional-defiant, conduct, and obsessive-compulsive problems were rated for 12,310 twin pairs from the Netherlands Twin Register by mothers (N = 12,085) and fathers (N = 8,516). The effects of genetic and non-genetic effects were estimated on the common and rater-specific variance. For all scales, mean scores on maternal ratings exceeded paternal ratings. Parents largely agreed on the ranking of their child's problems (r 0.60-0.75). The heritability was estimated over 55% for maternal and paternal ratings for all scales, except for conduct problems (44-46%). Unbiased shared environmental influences, i.e., on the common variance, were significant for affective (13%), oppositional (13%), and conduct problems (37%). In clinical settings, different cutoffs for (sub)clinical scores could be applied to paternal and maternal ratings of their child's psychopathology. Only for conduct problems, shared environmental and genetic influences explain an equal amount in differences between children. For the other scales, genetic factors explain the majority of the variance, especially for the common part that is free of rater bias. © 2016 The Authors.

    2015-01-01

    The experience of social anxiety has largely been investigated among Western populations; much less is known about social anxiety in other cultures. Unlike the Western culture, the Chinese emphasize interdependence and harmony with social others. In addition, it is unclear if Western constructed instruments adequately capture culturally conditioned conceptualizations and manifestations of social anxiety that might be specific to the Chinese. The present study employed a sequence of qualitative and quantitative approaches to examine the assessment of social anxiety among the Chinese people. Interviews and focus group discussions with Chinese participants revealed that some items containing the experience of social anxiety among the Chinese are not present in existing Western measures. Factor analysis was employed to examine the factor structure of the more comprehensive scale. This approach revealed an "other concerned anxiety" factor that appears to be specific to the Chinese. Subsequent analysis found that the new factor-other concerned anxiety-functioned the same as other social anxiety factors in their association with risk factors of social anxiety, such as attachment, parenting, behavioral inhibition/activation, and attitude toward group. The implications of these findings for a more culturally sensitive assessment tool of social anxiety among the Chinese were discussed.

    Anxiety and its associated disorders are common in patients with cardiovascular disease and may significantly influence cardiac health. Anxiety disorders are associated with the onset and progression of cardiac disease, and in many instances have been linked to adverse cardiovascular outcomes, including mortality. Both physiologic (autonomic dysfunction, inflammation, endothelial dysfunction, changes in platelet aggregation) and health behavior mechanisms may help to explain the relationships between anxiety disorders and cardiovascular disease. Given the associations between anxiety disorders and poor cardiac health, the timely and accurate identification and treatment of these conditions is of the utmost importance. Fortunately, pharmacologic and psychotherapeutic interventions for the management of anxiety disorders are generally safe and effective. Further study is needed to determine whether interventions to treat anxiety disorders ultimately impact both psychiatric and cardiovascular health.

    Multiple paternity appears to be a common trait of elasmobranch mating systems, with its occurrence likely driven by convenience, due to females seeking to minimize the stress of male harassment. Here we use molecular markers to analyse the frequency of multiple paternity in two related viviparous sharks, Mustelus mustelus and Mustelus punctulatus. We first applied molecular methods to assign pregnant females, embryos and additional reference adults (N = 792) to one of the two species. Paternity analysis was performed using a total of 9 polymorphic microsatellites on 19 females and 204 embryos of M. mustelus, and on 13 females and 303 embryos of M. punctulatus. Multiple paternity occurs in both species, with 47% of M. mustelus and 54% of M. punctulatus litters sired by at least two fathers. Female fecundity is not influenced by multiple mating and in 56% of polyandrous litters paternity is skewed, with one male siring most of the pups. Genetic analyses also revealed hybridization between the two species, with a M. punctulatus female bearing pups sired by a M. mustelus male. The frequency of polyandrous litters in these species is consistent with aspects of their reproductive biology, such as synchronous ovulation and possible occurrence of breeding aggregations.

    The aim of this study was to explore the role of the paternity leave in the appearance of the maternal postpartum depression. Fifty-one couples took part in the whole study. Between the second and the fifth day after the childbirth, the mother completed the Edinburgh Postnatal Depression Scale (EPDS), which measures the symptoms of depression and the Multidimensional Scale of Perceived Social Support (MSPSS) which measures the social support the mother has become. The father completed the EPDS. Two months and then the second time four months after the childbirth, the mother received the EPDS, the MSPSS, and questionnaires measuring the temperament of the baby, the maternal skills, the feeling of being a mother and the quality of life postpartum. In order to evaluate the paternal involvement, the father completed the EPDS and questions about paternal skills and involvement. The paternity leave seemed not to have any consequences on the results at the EPDS or other questionnaires. However, lack of paternal involvement was a significant predictor of the intensity of the depressive symptoms of the mothers. It is not the presence of the father wich seems important to take into account for detection and the traitement of postpatum depression but his participation in the care of the baby.

    Biparental care of offspring occurs in diverse mammalian genera and is particularly common among species with socially monogamous mating systems. Despite numerous well-documented examples, however, the evolutionary causes and consequences of paternal care in mammals are not well understood. Here, we investigate the evolution of paternal care in relation to offspring production. Using comparative analyses to test for evidence of evolutionary associations between male care and life-history traits, we explore if biparental care is likely to have evolved because of the importance of male care to offspring survival, or if evolutionary increases in offspring production are likely to result from the evolution of biparental care. Overall, we find no evidence that paternal care has evolved in response to benefits of supporting females to rear particularly costly large offspring or litters. Rather, our findings suggest that increases in offspring production are more likely to follow the evolution of paternal care, specifically where males contribute depreciable investment such as provisioning young. Through coevolution with litter size, we conclude that paternal care in mammals is likely to play an important role in stabilizing monogamous mating systems and could ultimately promote the evolution of complex social behaviours. © 2016 The Authors.

    Understanding causes of variation in promiscuity within populations remain a major challenge. While most studies have focused on quantifying fitness costs and benefits of promiscuous behaviour, an alternative possibility--that variation in promiscuity within populations is maintained because of linkage with other traits-has received little attention. Here, we examine whether promiscuity in male and female great tits (Parus major)--quantified as extra-pair paternity (EPP) within and between nests--is associated with variation in a well-documented personality trait: exploration behaviour in a novel environment. Exploration behaviour has been shown to correlate with activity levels, risk-taking and boldness, and these are behaviours that may plausibly influence EPP. Exploration behaviour correlated positively with paternity gained outside the social pair among males in our population, but there was also a negative correlation with paternity in the social nest. Hence, while variation in male personality predicted the relative importance of paternity gain within and outside the pair bond, total paternity gained was unrelated to exploration behaviour. We found evidence that males paired with bold females were more likely to sire extra-pair young. Our data thus demonstrate a link between personality and promiscuity, with no net effects on reproductive success, suggesting personality-dependent mating tactics, in contrast with traditional adaptive explanations for promiscuity.

    Full Text Available Abstract Background Parental history of mood or anxiety disorders is one of the strongest and most consistent risk factors for the development of these disorders in offspring. Gaps remain however in our knowledge of whether maternal or paternal disorders are more strongly associated with offspring disorders, and whether the association exists in non-clinical samples. This study uses a large population-based sample to test if maternal or paternal history of mood and/or anxiety disorders increases the risk of mood and/or anxiety disorders, or symptoms of specific anxiety disorders, in offspring. Methods Data were drawn from the Nicotine Dependence in Teens Study, a prospective cohort investigation of 1293 grade 7 students. Data on mental health outcomes were collected in mailed self-report questionnaires when participants were aged 20.4 (0.7 years on average. Parental data were collected in mailed self-report questionnaires. This current analysis pertains to 564 participants with maternal and/or paternal data. The association between maternal and paternal history and each of diagnosed anxiety disorder, diagnosed mood disorder, and symptoms of specific anxiety disorders in offspring was studied in multivariate logistic regression. Results A higher proportion of mothers than fathers had a diagnosed mood/anxiety disorder (23% versus 12%. Similarly, 14% of female offspring had a diagnosed mood/anxiety disorder, compared to 6% of male offspring. The adjusted odds ratio (95% confidence interval for maternal history was 2.2 (1.1, 4.5 for diagnosed mood disorders, 4.0 (2.1, 7.8 for diagnosed anxiety disorders, and 2.2 (1.2, 4.0 for social phobia symptoms. Paternal history was not associated with any of the mental health outcomes in offspring. Conclusion Maternal, but not paternal mood/anxiety disorders were associated with diagnosed psychiatric disorders, as well as symptoms of specific anxiety disorders, in offspring.

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

    Full Text Available The utility of the Philippines genetic database consisting of seven Short Tandem Repeat (STR markers for testing of ten questioned paternity cases was investigated. The markers used were HUMvWA, HUMTH01, HUMCSF1PO, HUMFOLP23, D8S306, HUMFES/FPS, and HUMF13A01. These markers had a combined Power of Paternity Exclusion of 99.17%. Due to the gravity of some cases handled in the laboratory, routine procedures must be assessed to determine the capacity of the analysis to exclude a non-father of predict paternity. Clients showed a preference for only testing father and child to lower costs and reduce conflicts, particularly when the mother objects to the conduct of DNA tests, or when she is deceased or cannot be located. The Probability of Paternity was calculated with and without the mother’s profile in each of the cases. In all instances, results were more informative when the mother’s DNA profile was included. Moreover, variations in the allelic distribution of five STR markers among eight Caucasian, one African-American, and two Amerindian (Argentina populations resulted in significant differences in Probability of Paternity estimates compared to those calculated using the Philippine Database.Based on the results of the present study, it is recommended that tests on alleged father-child samples be performed to screen for at least two mismatches. In the absence of theses mismatches, further analysis that includes the mother’s DNA profile is recommended. Moreover, it is recommended that a Philippines genetic database be used for DNA-based paternity testing in the Philippines.

    Advancing paternal age is associated with increased genetic mutations during spermatogenesis, which research suggests may cause psychiatric morbidity in the offspring. The effects of advancing paternal age at childbearing on offspring morbidity remain unclear, however, because of inconsistent epidemiologic findings and the inability of previous studies to rigorously rule out confounding factors. To examine the associations between advancing paternal age at childbearing and numerous indexes of offspring morbidity. We performed a population-based cohort study of all individuals born in Sweden in 1973-2001 (N = 2,615,081), with subsets of the data used to predict childhood or adolescent morbidity. We estimated the risk of psychiatric and academic morbidity associated with advancing paternal age using several quasi-experimental designs, including the comparison of differentially exposed siblings, cousins, and first-born cousins. Paternal age at childbearing. Psychiatric (autism, attention-deficit/hyperactivity disorder, psychosis, bipolar disorder, suicide attempt, and substance use problem) and academic (failing grades and low educational attainment) morbidity. In the study population, advancing paternal age was associated with increased risk of some psychiatric disorders (eg, autism, psychosis, and bipolar disorders) but decreased risk of the other indexes of morbidity. In contrast, the sibling-comparison analyses indicated that advancing paternal age had a dose-response relationship with every index of morbidity, with the magnitude of the associations being as large or larger than the estimates in the entire population. Compared with offspring born to fathers 20 to 24 years old, offspring of fathers 45 years and older were at heightened risk of autism (hazard ratio [HR] = 3.45; 95% CI, 1.62-7.33), attention-deficit/hyperactivity disorder (HR = 13.13; 95% CI, 6.85-25.16), psychosis (HR = 2.07; 95% CI, 1.35-3.20), bipolar disorder (HR = 24.70; 95% CI, 12

    The paternal uniparental disomy 14 is a rare malformation syndrome whose postnatal pathognomonic sign is the deformation of the rib as coat hanger. In prenatal, ultrasonographic signs are major recurrent polyhydramnios, a narrow thorax and deformed long bones short and sometimes other anomalies including ends. The authors report one rare case of prenatal paternal uniparental disomy 14 with the deformation of the rib as coat hanger. Prenatally, the narrow deformed thorax can be searched by ultrasound three-dimensional (3D) and/or helical CT and thus represent an aid to prenatal diagnosis. Copyright © 2013 Elsevier Masson SAS.

    2008-09-01

    From the era of the asylum to the present day, the architectural design of inpatient facilities has long been considered a contributing factor in the treatment of patients with mental and substance use disorders. The author examines the ethical basis for decisions about the design of psychiatric hospitals--architectural paternalism. The ethic of paternalism in the design of asylums and in contemporary thinking about psychiatric hospital design is described. The author argues that limitation of patients' autonomy and rights by the purpose-built architectural environment is legitimate and ethical.

    Full Text Available This paper aims at verifying if the measures adopted in Brazil for tobacco control are paternalistic and if they, in any way, restrict individual liberties. Firstly, some of the theories on paternalism and their relation to liberty will be analyzed, focusing on the Libertarian Paternalism doctrine. Then, measures for tobacco control adopted in other countries and in Brazil will be discussed. Finally, each measure adopted in Brazil will be thoroughly analyzed, in order to verify if it restricts liberty and if there are less restrictive measures available. The conclusion is that the measures adopted in Brazil, even though they are predominantly paternalistic, do not necessarily restrict individual liberties.

    Psychological functioning in fathers of children with Type 1 diabetes has received relatively little attention compared to mothers. This study examined fathers' perceived involvement in their children's diabetes care as it related to mothers' and fathers' pediatric parenting stress, depression, anxiety, marital satisfaction, and sleep, and to their children's diabetes regimen adherence and glycemic control. Eighty-two mothers and 43 fathers completed questionnaires. Multivariate linear regressions were conducted separately for mothers and fathers to determine the relationships between the perceived amount and the perceived helpfulness of father involvement in child diabetes care on parental psychosocial functioning and child diabetes control. Maternal perceptions of father helpfulness and amount of involvement in illness care were related to improved marital satisfaction and fewer depressive symptoms in mothers. In fathers, perception of their own amount of involvement was related to increased pediatric parenting stress and anxiety. Better child regimen adherence was associated with maternal perceptions of father helpfulness but not the amount of their involvement, while paternal perceptions of their own helpfulness were related to poorer glycemic control. These findings suggest that fathers and mothers may react differently to their roles in childhood illness and that perceptions of their involvement may be differently associated with children's glycemic control and regimen adherence.

  17. Maternal, not paternal PTSD, is related to increased risk for PTSD in offspring of Holocaust survivors

    2008-01-01

    Background A significant association between parental PTSD and the occurrence of PTSD in offspring has been noted, consistent with the idea that risk for PTSD is transmitted from parent to child. Two recent reports linking maternal PTSD and low cortisol in offspring prompted us to examine the relative contributions of maternal vs. paternal PTSD in the prediction of PTSD and other psychiatric diagnoses. Methods 117 men and 167 women, recruited from the community, were evaluated using a comprehensive psychiatric battery designed to identify traumatic life experiences and lifetime psychiatric diagnoses. 211 of the subjects were the adult offspring of Holocaust survivors and 73 were demographically comparable Jewish controls. Participants were further subdivided based on whether their mother, father, neither, or both parents met the diagnostic criteria for lifetime PTSD. Results A higher prevalence of lifetime PTSD, mood, anxiety disorders, and to a lesser extent, substance abuse disorders, was observed in offspring of Holocaust than controls. The presence of maternal PTSD was specifically associated with PTSD in adult offspring. However, the other diagnoses did not show specific effects associated with maternal PTSD. Conclusion The tendency for maternal PTSD to make a greater contribution to PTSD risk suggests that classic genetic mechanisms are not the sole model of transmission, and pave way for the speculation that epigenetic factors may be involved. In contrast, PTSD in any parent contributes to risk for depression, and parental traumatization is associated with increased anxiety disorders in offspring. PMID:18281061

    2003-04-01

    This review covers the effect of drugs affecting anxiety using four psychological procedures for inducing experimental anxiety applied to healthy volunteers and patients with anxiety disorders. The first is aversive conditioning of the skin conductance responses to tones. The second is simulated public speaking, which consists of speaking in front of a video camera, with anxiety being measured with psychometric scales. The third is the Stroop Color-Word test, in which words naming colors are painted in the same or in a different shade, the incongruence generating a cognitive conflict. The last test is a human version of a thoroughly studied animal model of anxiety, fear-potentiated startle, in which the eye-blink reflex to a loud noise is recorded. The evidence reviewed led to the conclusion that the aversive conditioning and potentiated startle tests are based on classical conditioning of anticipatory anxiety. Their sensitivity to benzodiazepine anxiolytics suggests that these models generate an emotional state related to generalized anxiety disorder. On the other hand, the increase in anxiety determined by simulated public speaking is resistant to benzodiazepines and sensitive to drugs affecting serotonergic neurotransmission. This pharmacological profile, together with epidemiological evidence indicating its widespread prevalence, suggests that the emotional state generated by public speaking represents a species-specific response that may be related to social phobia and panic disorder. Because of scant pharmacological data, the status of the Stroop Color-Word test remains uncertain. In spite of ethical and economic constraints, human experimental anxiety constitutes a valuable tool for the study of the pathophysiology of anxiety disorders.

  10. Mechanisms and consequences of paternally transmitted chromosomal abnormalities

    Energy Technology Data Exchange (ETDEWEB)

    Marchetti, F; Wyrobek, A J

    2005-04-05

    Paternally transmitted chromosomal damage has been associated with pregnancy loss, developmental and morphological defects, infant mortality, infertility, and genetic diseases in the offspring including cancer. There is epidemiological evidence linking paternal exposure to occupational or environmental agents with an increased risk of abnormal reproductive outcomes. There is also a large body of literature on germ cell mutagenesis in rodents showing that treatment of male germ cells with mutagens has dramatic consequences on reproduction producing effects such as those observed in human epidemiological studies. However, we know very little about the etiology, transmission and early embryonic consequences of paternally-derived chromosomal abnormalities. The available evidence suggests that: (1) there are distinct patterns of germ cell-stage differences in the sensitivity of induction of transmissible genetic damage with male postmeiotic cells being the most sensitive; (2) cytogenetic abnormalities at first metaphase after fertilization are critical intermediates between paternal exposure and abnormal reproductive outcomes; and, (3) there are maternally susceptibility factors that may have profound effects on the amount of sperm DNA damage that is converted into chromosomal aberrations in the zygote and directly affect the risk for abnormal reproductive outcomes.

    To compare asthma care roles of maternal and paternal caregivers, and examine associations between caregiver involvement and the outcomes of adherence, morbidity, and parental quality of life (QoL). Mothers and fathers in 63 families of children, ages 5-9 years, with persistent asthma completed semistructured interviews and questionnaires. Adherence was measured via electronic monitoring. Paired t tests compared parental asthma care roles, and analysis of covariance, controlling for socioeconomic status, evaluated associations of asthma outcomes with caregiver involvement scores. Mothers had higher scores on measures of involvement, beliefs in medication necessity, and on four subscales of the Family Asthma Management System Scale interview (Asthma Knowledge, Relationship with Provider, Symptom Assessment, and Response to Symptoms). Maternal QoL was lowest when both maternal and paternal involvement was high. Paternal involvement was associated with increased morbidity. There is room for enhancement of fathers' asthma care roles. Higher levels of paternal involvement may be driven by family need. © The Author 2015.

Survey data on recurrence of HG was compared between cases who had a paternity change between pregnancies and cases who did not. The percentage of HG pregnancies in women with the same partner for all pregnancies was not significantly different from the percentage of HG pregnancies in women who changed partners for at least one pregnancy (78% vs 71%, p > 0.05). Participants who did and did not change partners between their first and second pregnancies, were asked to rate their first and second pregnancy in regards to symptoms of HG. Neither the ratings nor the change in rating between pregnancies was significantly different between the two groups. Women reported HG in over 70% of their pregnancies regardless of a paternity change. Paternal genes expressed through the fetus do not have a significant effect on incidence or recurrence of HG. This study supports a strong maternal genetic factor involved in HG. However, because the recurrence risk is not 100%, other factors play a role. Identification of the predisposing gene(s) and other factors will determine the cause of this poorly understood complication of pregnancy.

    The cases of 15 men admitted to the neuropsychiatric service of a Navy hospital for somnambulism indicate that sleepwalking is an aggressive or sexual motor activity seemingly aimed primarily at a fear-inspiring father. Although the patients varied in age from 18 to 36 years and in rank from seaman to chief petty officer, eight being married and seven single, all were from small-town or rural homes in the low economic class. Their training was religious and strict. They professed great respect for their fathers, to the extent that they could not criticize them or acknowledge hostility toward them. Their relations with their mothers were in general not satisfactory. Apparently fear of the father and the inability to express resentment or aggression was applied to all situations so that the suppressed feelings could be released only in sleepwalking, nightmares and fantasies. These abnormalities, by making the patients conspicuous, increased their terror and anxiety. It is emphasized that sleepwalking activities, far from being harmless, may endanger the patient or those about him. Long-term psychotherapy is necessary for the disorders manifested by somnambulism.

    Full Text Available The experience of social anxiety has largely been investigated among Western populations; much less is known about social anxiety in other cultures. Unlike the Western culture, the Chinese emphasize interdependence and harmony with social others. In addition, it is unclear if Western constructed instruments adequately capture culturally conditioned conceptualizations and manifestations of social anxiety that might be specific to the Chinese. The present study employed a sequence of qualitative and quantitative approaches to examine the assessment of social anxiety among the Chinese people. Interviews and focus group discussions with Chinese participants revealed that some items containing the experience of social anxiety among the Chinese are not present in existing Western measures. Factor analysis was employed to examine the factor structure of the more comprehensive scale. This approach revealed an “other concerned anxiety” factor that appears to be specific to the Chinese. Subsequent analysis found that the new factor—other concerned anxiety—functioned the same as other social anxiety factors in their association with risk factors of social anxiety, such as attachment, parenting, behavioral inhibition/activation, and attitude toward group. The implications of these findings for a more culturally sensitive assessment tool of social anxiety among the Chinese were discussed.

    Social anxiety disorders are various, frequent and invalidant. Social phobia is characterized by marked and persistent fear of social or performance situations in which embarrassment may occur including, for example, fear of public speaking. In clinical setting, the majority of social phobics report fears of more than one type of social situation. Social phobia tends to develop early in life, with a life time prevalence of 2-4%. Pharmacotherapy and behavioural and cognitive therapy are communly used.

    The subjective experience of anxiety plays a central role in cognitive behavioral models of social anxiety disorder (SAD). However, much remains to be learned about the temporal dynamics of anxiety elicited by feared social situations. The aims of the current study were: 1) to compare anxiety trajectories during a speech task in individuals with SAD (n = 135) versus healthy controls (HCs; n = 47), and 2) to compare the effects of CBT on anxiety trajectories with a waitlist control condition. SAD was associated with higher levels of anxiety and greater increases in anticipatory anxiety compared to HCs, but not differential change in anxiety from pre- to post-speech. CBT was associated with decreases in anxiety from pre- to post-speech but not with changes in absolute levels of anticipatory anxiety or rates of change in anxiety during anticipation. The findings suggest that anticipatory experiences should be further incorporated into exposures. PMID:26760456

To this aim, untreated and neonatally-handled RHA-I and RLA-I rats of both sexes were tested in the following tests/tasks in baseline acoustic startle (BAS test, a context-conditioned fear (CCF test and the acquisition of two-way active –shuttle box- avoidance (SHAV. RLA-I rats showed higher unconditioned (NOE, ZM, BAS and conditioned (CCF, SHAV anxiety. H treatment increased exploration of the novel object in the NOE test as well as exploration of the open sections of the ZM test in both rat strains and sexes, although the effects were relatively more marked in the (high anxious RLA-I strain and in females. Neonatal handling did not affect BAS, but reduced context-conditioned fear in both strains and sexes, and improved shuttle box avoidance acquisition especially in RLA-I (and particularly in females and in female RHA-I rats. These are completely novel findings, and may suggest that H-induced changes in hippocampal function, which is enhanced in RLA-Is vs RHA-I rats, could be a candidate mechanism underlying the observed long-lasting benefits of neonatal handling on known hippocampal-dependent responses/tasks.

    2015-01-01

    Full Text Available One of the main objectives of parental leave policies aimed exclusively at fathers is to promote gender equality in the productive and reproductive spheres. The aim of this study is to examine whether the use of paternity leave fosters greater involvement of fathers in the division of tasks within the reproductive sphere, specifi cally child care and housework. Based on data from the survey, ?Social use of parental leave in Spain, 2012?, we have created multivariate models using ordinary least squares regression. The sample used in the analysis consists of 600 fathers who have had at least one child since 2007. The results suggest that paternity leave does encourage greater involvement by fathers in childcare, but the effect is limited, as it is only found for fathers after the birth of their fi rst child.

    To determine if adolescent obesity is associated with parenting characterized by lower sensitivity and lower monitoring of adolescent activities. We used data from 744 adolescents in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Height and weight were measured at age 15½ years and obesity defined as body mass index ≥ 95th percentile for age and sex. Maternal and paternal sensitivity were assessed by direct observation of a parent-adolescent interaction task. Maternal and paternal monitoring were assessed by parent report. Lower sensitivity and lower monitoring were each defined as the lowest quartiles. Two separate multivariate logistic regression models were created to evaluate, individually for mothers and fathers, associations of sensitivity and monitoring with adolescent obesity, controlling for adolescent sex and race, family income-to-needs ratio, and parental obesity. Fourteen percent of the adolescents were obese. Lower sensitivity was associated with adolescent obesity in the maternal parenting model (adjusted odds ratio [AOR] 2.36, 95% confidence interval [CI] 1.44-3.86, n = 709), but not paternal parenting model (AOR = 0.79, 95% CI 0.38-1.63, n = 460). Neither maternal nor paternal monitoring was associated with adolescent obesity (AOR = 1.03, 95% CI 0.63-1.68; AOR = 1.07, 95% CI 0.52-2.22, respectively). Lower maternal sensitivity, measured by direct observation of parent-adolescent interactions, was associated with adolescent obesity. Efforts to prevent and treat childhood obesity, both at the practitioner level and the community level, may be enhanced by educating parents that their reactions to their children's behaviors may have consequences related to obesity.

  17. Male genotype affects female fitness in a paternally investing species.

    Science.gov (United States)

    2006-08-01

    Male nutrient provisioning is widespread in insects. Females of some species use male-derived nutrients for increased longevity and reproductive output. Despite much research into the consequences of paternal nutrient investment for male and female fitness, the heritability, and therefore the potential of this trait to respond to selection, has rarely been examined. Males of several butterfly species provide the female with nutrients in the spermatophore at mating. Females of the green-veined white butterfly Pieris napi (Lepidoptera: Pieridae) use male donations both for developing eggs (resulting in higher lifetime fecundity of multiply mated females), but also for their somatic maintenance (increasing longevity). Using half-sib, father-son regression and full-sib analyses, I showed that paternal nutrient investment is heritable, both in terms of the absolute but also the relative size of the spermatophore (controlling for body size). Male size and spermatophore size were also genetically correlated. Furthermore, a separate study showed male genotype had a significant effect on female longevity and lifetime fecundity. In contrast, male genotype had no influence on the immediate egg-laying rate of females following mating, suggesting limited scope for male manipulation of immediate female oviposition. These results indicate that females may derive both direct (increased lifetime fecundity and longevity) and indirect (sons with greater reproductive success) fitness benefits from paternal nutrient donations in this species.

    We develop and test a conceptual model of factors influencing the likelihood of physical wife abuse. The paternal disinvestment model emphasizes that spousal conflict over resource use results from men's attempts to increase individual fitness at a cost to the family (e.g., through pursuit of extramarital affairs). We propose that men use violence to control women's responses to the diversion of resources away from the family: to quell women's objections to male disinvestment, maintain women's parental investment, and to dissuade women from pursuing relationships with other men. Interviews were conducted among men and women to determine rates of violence and demographic and behavioral covariates. Structural equation modeling and generalized estimating equations analyses were used to test predictions derived from the model. We also collected data on frequent complaints in marriage and women's perceptions of arguments precipitating violence. Over 85% of women experienced physical wife abuse (n = 49). Indicators of paternal disinvestment positively covary with indicators of marital strife and with rates of wife abuse. The wife's age, matrilocal residence, and presence of joint dependent offspring decrease the likelihood of violence through direct and indirect routes. Wife abuse is linked to the importance of paternal investment in human families, and is a means by which men control women's responses to a dual reproductive strategy of familial investment and pursuit of extramarital sexual relationships. This framework is more general than traditional sociological and evolutionary perspectives emphasizing patriarchy and men's sexual jealousy, respectively. Copyright © 2011 Wiley-Liss, Inc.

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

    Partner education during pregnancy may be able to prevent postnatal mental health problems, and support expectant fathers in their transition to parenthood. The aim of this systematic review is to investigate the effects of prenatal childbirth education among partners of pregnant women, particularly regarding paternal postnatal mental health and couple relationship. We searched Medline, CINAHL, EMBASE, PsycINFO, ERIC, and CENTRAL using terms such as "partners of pregnant women," "education," and "prenatal support." Searches were limited to randomized trials. We included 11 trials out of 13 reports that addressed the following topics: childbirth preparation, couple relationship, infants and parenting, postpartum psychosocial issues, and housework sharing. Overall risk of bias was low or unclear. Study outcomes, including parents' mental health (e.g., anxiety, depression, distress), couple relationship, parents' transition adjustment and parenting stress, and parents' satisfaction with their experience of childbirth and prenatal childbirth education programs were reported. The studies included in this review were very diverse regarding intervention intensity and content, outcome types, measurement tools, and outcome timing. This impeded evaluation of the interventions' effectiveness. No sufficient evidence was identified that prenatal childbirth education for partners of pregnant women protects against paternal postnatal depression and couple relationship; however, paternal postnatal mental health is important to maternal and perinatal healthcare. The results of this review suggest that further research and intervention are required to provide partners of pregnant women with evidence-based information and support whole families during the perinatal period.

    A sexual assault case resulted in a pregnancy, which was subsequently aborted. The alleged father of the fetus was unknown. Maternal and fetal types were obtained using the 11-locus AmpFℓSTR(®) SGM Plus(®) kit. The national DNA database was searched for the paternal obligatory alleles and detected two suspects who could not be excluded as father of the male fetus. Additional typing using the AmpFℓSTR(®) Minifiler(™) kit, containing three additional autosomal loci, was not sufficient to exclude either suspect. Subsequent typing using the PowerPlex(®) 16, containing four additional loci, and Y-Filer(™) kits resulted in excluding one suspect. Searching a database for paternal obligatory alleles can be fruitful, but is fraught with possible false positive results so that finding a match must be taken as only preliminary evidence. © 2012 American Academy of Forensic Sciences.

    Activating mutations in the KCNJ11 and ABCC8 genes encoding the Kir6.2 and SUR1 subunits of the pancreatic ATP-sensitive K(+) channel are the most common cause of permanent neonatal diabetes. In contrast to KCNJ11, where only dominant heterozygous mutations have been identified, recessively acting ABCC8 mutations have recently been found in some patients with neonatal diabetes. These genes are co-located on chromosome 11p15.1, centromeric to the imprinted Beckwith-Wiedemann syndrome (BWS) locus at 11p15.5. We investigated a male with hemihypertrophy, a condition classically associated with neonatal hyperinsulinemia and hypoglycemia, who developed neonatal diabetes at age 5 weeks. The KCNJ11 and ABCC8 genes and microsatellite markers on chromosome 11 were analyzed in DNA samples from the patient and his parents. A paternally inherited activating mutation (N72S) in the ABCC8 gene was identified in the proband. The mutation was present at 70% in the patient's leukocytes and 50% in buccal cells. Microsatellite analysis demonstrated mosaic segmental paternal uniparental isodisomy (UPD) of 11pter-11p14 in the proband that encompassed the ABCC8 gene and the BWS locus. We report a patient with neonatal diabetes, hemihypertrophy, and relatively high birth weight resulting from telomeric segmental paternal UPD of chromosome 11, which unmasks a recessively acting gain-of-function mutation in the ABCC8 gene and causes deregulation of imprinted genes at the BWS locus on 11p15.5.

    Alkozei, Anna; Cooper, Peter J.; Creswell, Cathy

    2014-01-01

    Background Two specific cognitive constructs that have been implicated in the development and maintenance of anxiety symptoms are anxiety sensitivity and emotional reasoning, both of which relate to the experience and meaning of physical symptoms of arousal or anxiety. The interpretation of physical symptoms has been particularly implicated in theories of social anxiety disorder, where internal physical symptoms are hypothesized to influence the individual's appraisals of the self as a social object. Method The current study compared 75 children on measures of anxiety sensitivity and emotional reasoning: 25 with social anxiety disorder, 25 with other anxiety disorders, and 25 nonanxious children (aged 7–12 years). Results Children with social anxiety disorder reported higher levels of anxiety sensitivity and were more likely than both other groups to view ambiguous situations as anxiety provoking, whether physical information was present or not. There were no group differences in the extent to which physical information altered children's interpretation of hypothetical scenarios. Limitations This study is the first to investigate emotional reasoning in clinically anxious children and therefore replication is needed. In addition, those in both anxious groups commonly had comorbid conditions and, consequently, specific conclusions about social anxiety disorder need to be treated with caution. Conclusion The findings highlight cognitive characteristics that may be particularly pertinent in the context of social anxiety disorder in childhood and which may be potential targets for treatment. Furthermore, the findings suggest that strategies to modify these particular cognitive constructs may not be necessary in treatments of some other childhood anxiety disorders. PMID:24120086

    Researchers have uncovered inconsistent relations between anxiety and performance. Although the prominent view is a "dark side," where anxiety has a negative relation with performance, a "bright side" of anxiety has also been suggested. We reconcile past findings by presenting a comprehensive multilevel, multiprocess model of workplace anxiety called the theory of workplace anxiety (TWA). This model highlights the processes and conditions through which workplace anxiety may lead to debilitative and facilitative job performance and includes 19 theoretical propositions. Drawing on past theories of anxiety, resource depletion, cognitive-motivational processing, and performance, we uncover the debilitative and facilitative nature of dispositional and situational workplace anxiety by positioning emotional exhaustion, self-regulatory processing, and cognitive interference as distinct contrasting processes underlying the relationship between workplace anxiety and job performance. Extending our theoretical model, we pinpoint motivation, ability, and emotional intelligence as critical conditions that shape when workplace anxiety will debilitate and facilitate job performance. We also identify the unique employee, job, and situational characteristics that serve as antecedents of dispositional and situational workplace anxiety. The TWA offers a nuanced perspective on workplace anxiety and serves as a foundation for future work. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Interventions targeting parents' mental health in the perinatal period are critical due to potential consequences of perinatal mental illness for the parent, the infant, and their family. To date, most programs have targeted mothers. This systematic review explores the current status and evidence for intervention programs aiming to prevent or treat paternal mental illness in the perinatal period. Electronic databases were systematically searched to identify peer-reviewed studies that described an intervention targeting fathers' mental health in the perinatal period. Mental health outcomes included depression, anxiety, and stress as well as more general measures of psychological functioning. Eleven studies were identified. Three of five psychosocial interventions and three massage-technique interventions reported significant effects. None of the couple-based interventions reported significant effects. A number of methodological limitations were identified, including inadequate reporting of study designs, and issues with the timing of interventions. The variability in outcomes measures across the studies made it difficult to evaluate the overall effectiveness of the interventions. Father-focused interventions aimed at preventing perinatal mood problems will be improved if future studies utilize more rigorous research strategies. © 2016 Michigan Association for Infant Mental Health.

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

    Short tandem repeats (STRs) and single nucleotide polymorphisms (SNPs) have been already used to perform noninvasive prenatal paternity testing from maternal plasma DNA. The frequently used technologies were PCR followed by capillary electrophoresis and SNP typing array, respectively. Here, we developed a noninvasive prenatal paternity testing (NIPAT) based on SNP typing with maternal plasma DNA sequencing. We evaluated the influence factors (minor allele frequency (MAF), the number of total SNP, fetal fraction and effective sequencing depth) and designed three different selective SNP panels in order to verify the performance in clinical cases. Combining targeted deep sequencing of selective SNP and informative bioinformatics pipeline, we calculated the combined paternity index (CPI) of 17 cases to determine paternity. Sequencing-based NIPAT results fully agreed with invasive prenatal paternity test using STR multiplex system. Our study here proved that the maternal plasma DNA sequencing-based technology is feasible and accurate in determining paternity, which may provide an alternative in forensic application in the future.

  13. Sperm length variation as a predictor of extrapair paternity in passerine birds

    OpenAIRE

    Lifjeld, J. T.; Laskemoen, T.; Kleven, O.; Albrecht, T. (Tomáš); Robertson, R. J.

    2010-01-01

    BACKGROUND: The rate of extrapair paternity is a commonly used index for the risk of sperm competition in birds, but paternity data exist for only a few percent of the approximately 10400 extant species. As paternity analyses require extensive field sampling and costly lab work, species coverage in this field will probably not improve much in the foreseeable future. Recent findings from passerine birds, which constitute the largest avian order (∼5,900 species), suggest that sperm phenotypes c...

    2014-01-01

    The frequency of extrapair paternity within populations has been hypothesized to be related to ecological and social factors, which in turn can determine the impact of extrapair paternity on the opportunity for sexual selection. Here, we use the blue tit Cyanistes caeruleus as study species to assess both issues. In particular, we analyze patterns of extrapair paternity in 12 nest-box plots that greatly vary in local population size, level of nest-box aggregation, and breeding density. We fou...

  15. Consistent paternity skew through ontogeny in Peron's tree frog (Litoria peronii.

    Directory of Open Access Journals (Sweden)

    Craig D H Sherman

    Full Text Available BACKGROUND: A large number of studies in postcopulatory sexual selection use paternity success as a proxy for fertilization success. However, selective mortality during embryonic development can lead to skews in paternity in situations of polyandry and sperm competition. Thus, when assessment of paternity fails to incorporate mortality skews during early ontogeny, this may interfere with correct interpretation of results and subsequent evolutionary inference. In a previous series of in vitro sperm competition experiments with amphibians (Litoria peronii, we showed skewed paternity patterns towards males more genetically similar to the female. METHODOLOGY/PRINCIPAL FINDINGS: Here we use in vitro fertilizations and sperm competition trials to test if this pattern of paternity of fully developed tadpoles reflects patterns of paternity at fertilization and if paternity skews changes during embryonic development. We show that there is no selective mortality through ontogeny and that patterns of paternity of hatched tadpoles reflects success of competing males in sperm competition at fertilization. CONCLUSIONS/SIGNIFICANCE: While this study shows that previous inferences of fertilization success from paternity data are valid for this species, rigorous testing of these assumptions is required to ensure that differential embryonic mortality does not confound estimations of true fertilization success.

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

  17. Direct benefits and genetic costs of extrapair paternity for female American crows (Corvus brachyrhynchos).

    Townsend, Andrea K; Clark, Anne B; McGowan, Kevin J

    2010-01-01

    The idea that extrapair paternity (EPP) in birds is part of a mixed reproductive strategy driven primarily by females is controversial. In cooperatively breeding American crows, we compared predictions of four female benefits hypotheses-the genetic diversity, good genes, genetic compatibility, and direct benefits hypotheses-to our predictions if EPP was primarily male driven. We found that genetically diverse broods were not more successful, extrapair young were not in better condition and did not have a higher survival probability, and, contrary to prediction, offspring sired by within-group extrapair males were more inbred than within-pair offspring. There was evidence of direct benefits, however: provisioning rate and number of surviving offspring were higher in groups containing within-group extrapair sires. Females therefore derived no apparent benefits from extragroup extrapair males but both direct benefits and genetic costs from within-group extrapair males. We suggest that males and females both influence the distribution of EPP in this system.

  18. Sexual selection resulting from extrapair paternity in collared flycatchers.

    1999-02-01

    Extrapair paternity has been suggested to represent a potentially important source of sexual selection on male secondary sexual characters, particularly in birds with predominantly socially monogamous mating systems. However, relatively few studies have demonstrated sexual selection within single species by this mechanism, and there have been few attempts to assess the importance of extrapair paternity in relation to other mechanisms of sexual selection. We report estimates of sexual selection gradients on male secondary sexual plumage characters resulting from extrapair paternity in the collared flycatcher Ficedula albicollis, and compare the importance of this form of sexual selection with that resulting from variation in mate fecundity. Microsatellite genotyping revealed that 15% of nestlings, distributed nonrandomly among 33% of broods (N=79), were the result of extrapair copulations. Multivariate selection analyses revealed significant positive directional sexual selection on two uncorrelated secondary sexual characters in males (forehead and wing patch size) when fledgling number was used as the measure of fitness. When number of offspring recruiting to the breeding population was used as the measure of male fitness, selection on these traits appeared to be directional and stabilizing, respectively. Pairwise comparisons of cuckolded and cuckolding males revealed that males that sired young through extrapair copulations had wider forehead patches, and were paired to females that bred earlier, than the males that they cuckolded. Path analysis was used to partition selection on these traits into pathways via mate fecundity and sperm competition, and suggested that the sperm competition pathway accounted for between 64 and 90% of the total sexual selection via the two paths. The selection revealed in these analyses is relatively weak in comparison with many other measures of selection in natural populations. We offer some explanations for the relatively weak

    Research into anxiety has largely ignored the dynamics of family systems in anxiety development. Coparenting refers to the quality of coordination between individuals responsible for the upbringing of children and links different subsystems within the family, such as the child, the marital relationship, and the parents. This review discusses the potential mechanisms and empirical findings regarding the bidirectional relations of parent and child anxiety with coparenting. The majority of studies point to bidirectional associations between greater coparenting difficulties and higher levels of anxiety. For example, the few available studies suggest that paternal and perhaps maternal anxiety is linked to lower coparental support. Also, research supports the existence of inverse links between coparenting quality and child anxiety. A child's reactive temperament appears to have adverse effects on particularly coparenting of fathers. A conceptual model is proposed that integrates the role of parental and child anxiety, parenting, and coparenting, to guide future research and the development of clinical interventions. Future research should distinguish between fathers' and mothers' coparenting behaviors, include parental anxiety, and investigate the coparental relationship longitudinally. Clinicians should be aware of the reciprocal relations between child anxiety and coparenting quality, and families presenting for treatment who report child (or parent) anxiety should be assessed for difficulties in coparenting. Clinical approaches to bolster coparenting quality are called for.

  20. Cognitive bias modification for interpretation with and without prior repetitive negative thinking to reduce worry and rumination in generalised anxiety disorder and depression: protocol for a multisession experimental study with an active control condition.

    Worry and rumination are two forms of repetitive thinking characterised by their negative content and apparently uncontrollable nature. Although worry and rumination share common features and have been conceptualised as part of a transdiagnostic repetitive negative thinking (RNT) process, it remains unclear whether they share the same underlying cognitive mechanisms. This multisession experimental study investigates the tendency to make negative interpretations regarding ambiguous information as a cognitive mechanism underlying RNT. We compare multisession cognitive bias modification for interpretations (CBM-I) with an active control condition to examine whether repeatedly training positive interpretations reduces worry and rumination in individuals with generalised anxiety disorder or depression, respectively. Further, we examine the potential modulatory effects of engaging in RNT immediately prior to CBM-I. A community sample of individuals meeting diagnostic criteria for either generalised anxiety disorder (n=60) or current major depressive episode (n=60) will be randomly allocated to CBM-I with prior RNT, CBM-I without prior RNT (ie, standard CBM-I), or an active control (no resolution of ambiguity) condition. All conditions receive a 3-week internet-based intervention consisting of one initial session at the first study visit and nine home-based sessions of CBM-I training (or active control). We will assess and compare the effects of CBM-I with and without prior RNT on 'near-transfer' measures of interpretation bias closely related to the training as well as 'far-transfer' outcomes related to RNT and emotional distress. Impact on questionnaire measures will additionally be assessed at 1-month follow-up. Multigroup analyses will be conducted to assess the impact of CBM-I on near-transfer and far-transfer outcome measures. Published by the BMJ Publishing Group Limited.

    The aim of this investigation was to evaluate how parental anxiety predicted change in pediatric anxiety symptoms across four different interventions: cognitive-behavioral therapy, medication (sertraline; SRT), their combination (COMB), and pill placebo. Participants were 488 youths (ages 7-17) with separation anxiety disorder, generalized anxiety disorder, and/or social phobia and their primary caregivers. Latent growth curve modeling assessed how pre-treatment parental trait anxiety symptoms predicted trajectories of youth anxiety symptom change across 12 weeks of treatment at four time points. Interactions between parental anxiety and treatment condition were tested. Parental anxiety was not associated with youth's pre-treatment anxiety symptom severity. Controlling for parental trait anxiety, youth depressive symptoms, and youth age, youths who received COMB benefitted most. Counter to expectations, parental anxiety influenced youth anxiety symptom trajectory only within the SRT condition, whereas parental anxiety was not significantly associated with youth anxiety trajectories in the other treatment conditions. Specifically, within the SRT condition, higher levels of parental anxiety predicted a faster and greater reduction in youth anxiety over the acute treatment period compared to youths in the SRT condition whose parents had lower anxiety levels. While all active treatments produced favorable outcomes, results provide insight regarding the treatment-specific influence of parental anxiety on the time course of symptom change.

  2. [Anxiety, a basic human experience].

    Anxiety, unlike fear, which is strongly object-related, accompanies man all his life. This anxious condition appears especially then, when danger is imminent, also in the case of being severely ill. Anxiety and hope, even in people severely ill, do not exclude each other. Human life for many and perhaps for all is a race with time. The anxiety not being able to realize enough in a given time often is the reason for a busy and restless activity. Man often suffers from anxiety of other human beings. As ever an individual may live, it always owes something to others. Accordingly, the doctor or other helpers never are able to behave totally in the way as the patient expects and the patient cannot act as the helper truly would like it. Man experiences anxiety, however, also then, when he recognizes to remain in debts towards himself and, in the view of religion, towards a task given by God. Yet, man suffers anxiety not only because of his confrontation with death but also with life and the responsibilities which he has to take over when growing up in society. The struggle for existence described by Darwin, a result of anxiety, seems to be lost for the patient knowing he or she is severely ill, and he/she is therefore upset against a destiny which threatens to exclude him/her from the community of healthy people and perhaps soon from the living persons. Anxiety always turns also around the existence in the group.(ABSTRACT TRUNCATED AT 250 WORDS)

    Limited evidence exists regarding fitness-to-drive for people with the mental health conditions of schizophrenia, stress/anxiety disorder, depression, personality disorder and obsessive compulsive disorder (herein simply referred to as 'mental health conditions'). The aim of this paper was to systematically search and classify all published studies regarding driving for this population, and then critically appraise papers addressing assessment of fitness-to-drive where the focus was not on the impact of medication on driving. A systematic search of three databases (CINAHL, PSYCHINFO, EMBASE) was completed from inception to May 2016 to identify all articles on driving and mental health conditions. Papers meeting the eligibility criteria of including data relating to assessment of fitness-to-drive were critically appraised using the American Academy of Neurology and Centre for Evidence-Based Medicine protocols. A total of 58 articles met the inclusion criteria of driving among people with mental health conditions studied, and of these, 16 contained data and an explicit focus on assessment of fitness-to-drive. Assessment of fitness-to-drive was reported in three ways: 1) factors impacting on the ability to drive safely among people with mental health conditions, 2) capability and perception of health professionals assessing fitness-to-drive of people with mental health conditions, and 3) crash rates. The level of evidence of the published studies was low due to the absence of controls, and the inability to pool data from different diagnostic groups. Evidence supporting fitness-to-drive is conflicting. There is a relatively small literature in the area of driving with mental health conditions, and the overall quality of studies examining fitness-to-drive is low. Large-scale longitudinal studies with age-matched controls are urgently needed in order to determine the effects of different conditions on fitness-to-drive.

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

    Full Text Available Anxiety disorders are highly prevalent among children and are associated with serious morbidity. Lifetime prevalence of paediatric anxiety disorders is about fifteen percent. Social phobia, generalized anxiety disorder and separation anxiety disorder are included in the triad of paediatric anxiety disorders. Specific phobia, obsessive compulsive disorder and post-traumatic stress disorder are also commonly seen in children. Overprotection by parents, parental death or separation, female sex, low educational status, family history of anxiety disorder, financial stress in family and adverse childhood experiences are risk factors for the development of anxiety disorders. If not diagnosed and managed at the earliest, paediatric anxiety disorders can cause life threatening problems in the future. Hence early and scientific management of anxiety disorders is essential. Cognitive behavioural therapy is the effective evidence based treatment for paediatric anxiety disorders.

  7. Paternity of subordinates raises cooperative effort in cichlids.

    Directory of Open Access Journals (Sweden)

    Rick Bruintjes

    Full Text Available In cooperative breeders, subordinates generally help a dominant breeding pair to raise offspring. Parentage studies have shown that in several species subordinates can participate in reproduction. This suggests an important role of direct fitness benefits for cooperation, particularly where groups contain unrelated subordinates. In this situation parentage should influence levels of cooperation. Here we combine parentage analyses and detailed behavioural observations in the field to study whether in the highly social cichlid Neolamprologus pulcher subordinates participate in reproduction and if so, whether and how this affects their cooperative care, controlling for the effect of kinship.We show that: (i male subordinates gained paternity in 27.8% of all clutches and (ii if they participated in reproduction, they sired on average 11.8% of young. Subordinate males sharing in reproduction showed more defence against experimentally presented egg predators compared to subordinates not participating in reproduction, and they tended to stay closer to the breeding shelter. No effects of relatedness between subordinates and dominants (to mid-parent, dominant female or dominant male were detected on parentage and on helping behaviour.This is the first evidence in a cooperatively breeding fish species that the helping effort of male subordinates may depend on obtained paternity, which stresses the need to consider direct fitness benefits in evolutionary studies of helping behaviour.

    It has long been debated whether coercion can be justified as paternalism in the field of mental health and it is still a continuing issue of controversy today. This study analyses whether coercive intervention in mental health can be justified by the basic assumptions of paternalists: the assumption of incompetence, the assumption of dangerousness and the assumption of impairment. This study involved 248 patients: 158 (63.7%) were diagnosed with schizophrenia and 90 (36.3%) were diagnosed with mood disorder. In this study, experiences of coercion were divided into legal status, subjective (perceived coercion) and objective experiences (experienced coercion). The assumption of incompetence was justified in all three categories of coercion whereas the assumption of dangerousness was not justified in any. The assumption of impairment was not justified in legal status and perceived coercion, but provided a partial explanation to serve as a basis for justifying experienced coercive measures. It can be noted that mental health experts who support paternalism without question must reconsider their previous methods. Above all, the reason why the assumption of dangerousness was not justified in any of the categories of coercion was because coercive intervention used to prevent harm to oneself and others must be very carefully carried out.

    Full Text Available The Dardenne brothers’ filmic production aims at restoring the missing link between human beings and the world that has been progressively undermined during the ultimate development of late-capitalist society. This contribution deals with their search for a new contact with reality and a concrete belief in the world, focusing on the theme of body and paternity, in the epoch of their evaporation. However, in or¬der to rethink the paternal function in a post-political and post-ideological age, the Dardennes have had to radically come to terms with its ambiguity and oscillation be¬tween abandon and adoption, self-preservation and transmission, forgiveness and revenge. With regard to this ambivalence, this contribution focuses on two films by the Dardennes, La promesse (The Promise, BE/FR/LU/TN 1996 and Le fils (The Son, BE/FR 2002, which represent significant descriptions of what (the body of a father is capable of, suggesting, at the same time, interruption and filiation as possible experi¬ences for a new beginning.

  10. The snail's love-dart delivers mucus to increase paternity.

    Many of the seemingly bizarre animal behaviours can be understood only by acknowledging the power of sex to shape evolution. A case in point is the so-called love-dart that some terrestrial molluscs shoot at their prospective sexual partners. Given that the likelihood of copulation is not different after solid hits than after complete misses, why do these suitors act so violently towards their chosen mates? Previously, it was shown that successful dart shooting enhances paternity. We conducted an experiment to determine whether the dart achieves its effect by a purely mechanical action or by transferring a bioactive substance. We found that injections of mucus from a gland associated with the dart more than doubled paternity relative to injections of saline. These results support the hypothesis that the dart transfers a substance capable of reconfiguring the spermatophore-receiving organs. While dart shooting probably evolved as the result of sperm competition, a role for cryptic female choice cannot be excluded. Our results imply that if cryptic female choice is operating in this system, it is likely to be based on the properties of the mucus and not on properties of the dart itself. Since we also found evidence of early-male sperm precedence, we conclude that snails can optimize their reproductive success by mating with virgins and shooting their darts accurately.

    We performed a paternity test in a case of incest between brother and sister. DNA from blood samples of the alleged parents and their two children was obtained with Chelex DNA extraction method and quantified with Applied Biosystems QuantiBlot quantitation kit. Polymerase chain reaction (PCR) amplification of DNA samples was performed with AmpFlSTR SGM Plus PCR amplification kit and GenePrint PowerPlex PCR amplification kit. The amplified products were separated and detected by using the Perkin Elmer's ABI PRISM trade mark 310 Genetic Analyser. DNA and data analysis of 17 loci and Amelogenin confirmed the suspicion of brother-sister incest. Since both children had inherited all of the obligate alleles from the alleged father, we could confirm with certainty of 99.999999% that the oldest brother in the family was the biological father of both children. Calculated data showed that even in a case of brother-sister incest, paternity could be proved by the analysis of Amelogenin and 17 DNA loci.

    This study examines the genetic variation in Basque Y chromosome lineages using data on 12 Y-short tandem repeat (STR) loci in a sample of 158 males from four Basque provinces of Spain (Alava, Vizcaya, Guipuzcoa, and Navarre). As reported in previous studies, the Basques are characterized by high frequencies of haplogroup R1b (83%). AMOVA analysis demonstrates genetic homogeneity, with a small but significant amount of genetic structure between provinces (Y-short tandem repeat loci STRs: 1.71%, p = 0.0369). Gene and haplotype diversity levels in the Basque population are on the low end of the European distribution (gene diversity: 0.4268; haplotype diversity: 0.9421). Post-Neolithic contribution to the paternal Basque gene pool was estimated by measuring the proportion of those haplogroups with a Time to Most Recent Common Ancestor (TMRCA) previously dated either prior (R1b, I2a2) or subsequent to (E1b1b, G2a, J2a) the Neolithic. Based on these estimates, the Basque provinces show varying degrees of post-Neolithic contribution in the paternal lineages (10.9% in the combined sample).

    The origins of the nearly one billion people inhabiting the Indian subcontinent and following the customs of the Hindu caste system are controversial: are they largely derived from Indian local populations (i.e. tribal groups) or from recent immigrants to India? Archaeological and linguistic evidence support the latter hypothesis, whereas recent genetic data seem to favor the former hypothesis. Here, we analyze the most extensive dataset of Indian caste and tribal Y chromosomes to date. We find that caste and tribal groups differ significantly in their haplogroup frequency distributions; caste groups are homogeneous for Y chromosome variation and more closely related to each other and to central Asian groups than to Indian tribal or any other Eurasian groups. We conclude that paternal lineages of Indian caste groups are primarily descended from Indo-European speakers who migrated from central Asia approximately 3,500 years ago. Conversely, paternal lineages of tribal groups are predominantly derived from the original Indian gene pool. We also provide evidence for bidirectional male gene flow between caste and tribal groups. In comparison, caste and tribal groups are homogeneous with respect to mitochondrial DNA variation, which may reflect the sociocultural characteristics of the Indian caste society.

    In all mammalian species, a combination of neuroendocrine and experiential factors contributes to the emergence of remarkable behavioral changes observed in parental behavior. Yet, our understanding of neuroendocrine bases of paternal behavior in humans is still preliminary and more research is needed in this area. In the present review, the authors summarized hormonal bases of paternal behavior in both human and nonhuman mammalian species and focused on studies on the regulatory role of prolactin in occurrence of paternal behavior. All peer-reviewed journal articles published before 2015 for each area discussed (parental brain, hormonal bases of maternal behavior, hormonal bases of paternal behavior and the role of prolactin in regulation of paternal behavior in nonhuman mammalian species, hormonal bases of paternal behavior and the role of prolactin in regulation of paternal behavior in humans) were searched by PubMed, Medline, and Scopus for original research and review articles. Publications between 1973 and 2015 were included. Similar to female parents, elevated prolactin levels in new fathers most probably contribute to child-caring behavior and facilitate behavioral and emotional states attributed to child care. Moreover, elevated parental prolactin levels after childbirth decrease the parents' libidos so that they invest more in parental care than in fertility behavior. According to the available clinical studies, elevation in the amounts of prolactin levels after childbirth in male parents are probably associated with paternal behavior observed in humans.

  10. Nicotine Modulation of Fear Memories and Anxiety: Implications for Learning and Anxiety Disorders

    Science.gov (United States)

    Kutlu, Munir Gunes; Gould, Thomas J.

    2015-01-01

    Anxiety disorders are a group of crippling mental diseases affecting millions of Americans with a 30% lifetime prevalence and costs associated with healthcare of $42.3 billion. While anxiety disorders show high levels of co-morbidity with smoking (45.3% vs. 22.5% in healthy individuals), anxiety disorders are also more common among the smoking population (22% vs. 11.1% in the non-smoking population). Moreover, there is clear evidence that smoking modulates symptom severity in patients with anxiety disorders. In order to better understand this relationship, several animal paradigms are used to model several key symptoms of anxiety disorders; these include fear conditioning and measures of anxiety. Studies clearly demonstrate that nicotine mediates acquisition and extinction of fear as well as anxiety through the modulation of specific subtypes of nicotinic acetylcholine receptors (nAChRs) in brain regions involved in emotion processing such as the hippocampus. However, the direction of nicotine’s effects on these behaviors is determined by several factors that include the length of administration, hippocampus-dependency of the fear learning task, and source of anxiety (novelty-driven vs. social anxiety). Overall, the studies reviewed here suggest that nicotine alters behaviors related to fear and anxiety and that nicotine contributes to the development, maintenance, and reoccurrence of anxiety disorders.

    Kenny, Dianna T; Davis, Pamela; Oates, Jenni

    2004-01-01

    This study explored the inter-relationships among state and trait anxiety, occupational stress, perfectionism, aspiration, and music performance anxiety in a group of elite operatic chorus artists employed full-time by a national opera company. The chorus artists reported higher trait anxiety, higher occupational role concerns, and higher occupational personal strain than normative samples. Higher scores on personal resources were associated with the higher scores on trait anxiety. It appears that these resources were used adaptively to manage anxiety. High trait anxiety was also associated with high personal strain in the work environment. Anxiety was not related to occupational roles or issues related to the physical environment or working conditions. These results suggest that while trait anxiety and music performance anxiety were closely associated, occupational stress makes a separate contribution to the quality of working life experienced by elite choral artists.

    A robust association between advancing paternal age and schizophrenia risk is reported, and genetic changes in the germ cells of older men are presumed to underlie the effect. If that is so, then the pathway may include effects on cognition, as those with premorbid schizophrenia are reported to have lower intelligence. There are also substantial genetic influences on intelligence, so de novo genetic events in male germ cells, which accompany advancing paternal age, may plausibly influence offspring intelligence. An association of paternal age with IQ in healthy adolescents may illuminate the mechanisms that link it to schizophrenia. We examined the association of paternal age and IQ scores using the Israeli Army Board data on 44 175 individuals from a richly described birth cohort, along with maternal age and other potential modifiers. A significant inverted U-shaped relationship was observed between paternal age and IQ scores, which was independent from a similar association of IQ scores with maternal age. These relationships were not significantly attenuated by controlling for multiple possible confounding factors, including the other parent's age, parental education, social class, sex and birth order, birth weight and birth complications. Overall, parental age accounted for approximately 2% of the total variance in IQ scores, with later paternal age lowering non-verbal IQ scores more than verbal IQ scores. We found independent effects of maternal and paternal age on offspring IQ scores. The paternal age effect may be explained by de novo mutations or abnormal methylation of paternally imprinted genes, whereas maternal age may affect fetal neurodevelopment through age-related alterations in the in-utero environment. The influence of late paternal age to modify non-verbal IQ may be related to the pathways that increase the risk for schizophrenia in the offspring of older fathers.

    Full Text Available Abstract Background The role of fathers in the development of obesity in their offspring remains poorly understood. We evaluated associations of missing paternal demographic information on birth certificates with perinatal risk factors for childhood obesity. Methods Data were from the Linked CENTURY Study, a database linking birth certificate and well-child visit data for 200,258 Massachusetts children from 1980–2008. We categorized participants based on the availability of paternal age, education, or race/ethnicity and maternal marital status on the birth certificate: (1 pregnancies missing paternal data; (2 pregnancies involving unmarried women with paternal data; and (3 pregnancies involving married women with paternal data. Using linear and logistic regression, we compared differences in smoking during pregnancy, gestational diabetes, birthweight, breastfeeding initiation, and ever recording a weight for length (WFL ≥ the 95th percentile or crossing upwards ≥2 WFL percentiles between 0–24 months among the study groups. Results 11,989 (6.0 % birth certificates were missing paternal data; 31,323 (15.6 % mothers were unmarried. In adjusted analyses, missing paternal data was associated with lower birthweight (β -0.07 kg; 95 % CI: −0.08, −0.05, smoking during pregnancy (AOR 4.40; 95 % CI: 3.97, 4.87, non-initiation of breastfeeding (AOR 0.39; 95 % CI: 0.36, 0.42, and with ever having a WFL ≥ 95th percentile (AOR 1.10; 95 % CI: 1.01, 1.20. Similar associations were noted for pregnancies involving unmarried women with paternal data, but differences were less pronounced. Conclusions Missing paternal data on the birth certificate is associated with perinatal risk factors for childhood obesity. Efforts to understand and reduce obesity risk factors in early life may need to consider paternal factors.

    2016-03-01

    Work anxiety is a potentially disabling mental health problem, which can cause (long-term) sickness absence. In many cases patients do not openly report their anxieties and tend to give externalizing explanations of inner problems. Therefore people with work anxiety may perceive their workplace more negatively than those without such anxiety. To investigate the relation between subjective work description and work anxiety. Work anxiety was investigated with a standardized interview in a sample of employed psychosomatic rehabilitation inpatients suffering from common mental disorders. We assessed their subjective perception and evaluation of workplace conditions with the 'Short Questionnaire for Job Analysis' (KFZA) and compared their results with those from a sample of employees in the general population. There were 148 inpatient participants and 8015 general population controls. Patients with work anxiety described their workplace significantly more negatively than patients without work anxiety and employees in the general population, with no differences in workplace descriptions between psychosomatic patients without work anxiety and the general population sample. The type of complaint about work conditions was related to the specific type of work anxiety. Reports about workplace burdens can be indicative of work anxiety and should prompt further in-depth assessments. The content of complaints about work conditions may point to the type of underlying work anxiety. © The Author 2015.

    2006-11-01

    In an immigration case with the scope of family reunification, the DNA extracted from the saliva samples of the male child, the alleged mother and the putative father was typed with 22 autosomal short tandem repeat (STR) systems. In seven STR systems, the alleged mother could be excluded from maternity, and the case then had to be regarded as a deficiency case. Taking this fact into consideration, only two exclusions were found for the putative father, and the question arose whether there was an exclusion of the putative father or the existence of two mutations. Autosomal STR typing could not clarify the case, but the application of eight Y-chromosomal markers showed that the alleged father could be excluded from paternity.

    1988-01-01

    Chloroplast DNA (cpDNA) was purified from Picea glauca, P. pungens, P. engelmannii, and P. omorika, and was digested with several restriction endonucleases. Interspecific restriction fragment length polymorphisms (RFLPs) of cpDNA were identified. The RFLPs were identified as cpDNA by the hybridization of cloned, 32 -P labeled, petunia cpDNA to the polymorphic bands, and by the lack of hybridization of a cloned and labeled mtDNA probe from maize. Chloroplast DNA RFLPs that showed no intraspecific variation when examined across the natural range for each species, were used as markers to follow the inheritance of plastids in interspecific hybrids. The inheritance of plastids was determined for F 1 -hybrids from reciprocal crosses of P. glauca and P. pungens, P. glauca and P. omorika, and F 1 -hybrids of P. engelmannii x pungens. All 31 F 1 -hybrids examined showed the cpDNA genotypes of the pollen parent, or the paternal species

    Full Text Available Abstract Although expression and epigenetic differences of imprinted genes have been extensively characterised in man and the mouse, little is known on livestock species. In this study, the polymorphism-based approach was used to detect the imprinting status of NNAT and DIRAS3 genes in five heterozygous pigs (based on SNP of Large White and Meishan F1 hybrids. The results show that both genes were paternally expressed in all the tested tissues (heart, liver, spleen, lung, kidney, stomach, small intestine, skeletal muscle, fat, uterus, ovary and pituitary. In addition, the NNAT gene had two transcripts in all tested tissues, which is consistent with its counterpart in man and cattle.

  4. Trans-generational parasite protection associated with paternal diet.

    2015-01-01

    Multiple generations of hosts are often exposed to the same pathogens, favouring the evolution of trans-generational defences. Because females have more opportunities to transfer protective molecules to offspring, many studies have focused on maternally derived protection. However, males of many species can transfer compounds along with sperm, including chemicals that could provide protection. Here, we assess maternally and paternally derived protection in a monarch butterfly-protozoan parasite system where parasite resistance is heavily influenced by secondary plant chemicals, known as cardenolides, present in the larval diet of milkweed plants. We reared monarch butterflies on medicinal and non-medicinal milkweed species and then measured resistance of their offspring to infection. We also measured cardenolide content in adult monarchs reared on the two species, and in the eggs that they produced. We found that offspring were more resistant to infection when their fathers were reared on medicinal milkweed, while maternal diet had less of an effect. We also found that eggs contained the highest levels of cardenolides when both parents were reared on the medicinal species. Moreover, females reared on non-medicinal milkweed produced eggs with significantly higher levels of cardenolides if they mated with males reared on the medicinal milkweed species. However, we found an equivocal relationship between the cardenolides present in eggs and parasite resistance in the offspring. Our results demonstrate that males reared on medicinal plants can transfer protection to their offspring, but the exact mechanism remains unresolved. This suggests that paternal protection from parasitism might be important, particularly when there are environmental sources of parasite resistance and when males transfer spermatophores during mating. © 2014 The Authors.

    The paper considers the efforts of two artist patients--one productive and the other not--to manage engulfment and separation anxiety through manipulations of virtual and literal spaces. The patients assumed characteristic emotional distances from their objects, subjects, products, audiences, and culture. More concretely, they developed artistic styles that, through formal structure and narrative content, signified a compromise between isolation and merger. Further investigation revealed that the productive patient's mother suffered a protracted postpartum depression that estranged her emotionally and physically from the patient in infancy. The tension between early maternal deprivation and later reaction-formed intrusiveness promoted the patient's aesthetic compromise between communication and concealment, permitting successful delivery of fantasy material. Although the unproductive patient portrayed repellent scenes which alienated her audience, she curiously never attempted stylistic corrections. Her press for merger was countered by a dread of contact conditioned by paternal abuse. Further exploration suggested that her artworks were not selfobjects, but rather close relations competing with her for audience attention.

    There is a lack of clarity regarding specific risk factors discriminating generalized anxiety disorder (GAD) from panic disorder (PD). This study investigated whether GAD and PD could be discriminated through differences in developmental etiological factors including childhood parental loss/separation, psychological disorders, and maternal and paternal attachment. Twenty people with adult generalized anxiety disorder (GAD), 20 with adult panic disorder (PD), 11 with adult comorbid GAD and PD, and 21 adult non-anxious controls completed diagnostic interviews to assess symptoms of mental disorders in adulthood and childhood. Participants also reported on parental attachment, loss and separation. Childhood diagnoses of GAD and PD differentiated clinical groups from controls as well as from each other, suggesting greater likelihood for homotypic over heterotypic continuity. Compared to controls, specific phobia was associated with all three clinical groups, and childhood depression, social phobia, and PTSD were uniquely associated with adult GAD. Both maternal and paternal attachment also differentiated clinical groups from controls. However, higher levels of subscales reflecting maternal insecure avoidant attachment (e.g., no memory of early childhood experiences and balancing/forgiving current state of mind) emerged as more predictive of GAD relative to PD. There were no group differences in parental loss or separation. These results support differentiation of GAD and PD based on developmental risk factors. Recommendations for future research and implications of the findings for understanding the etiology and symptomatology of GAD and PD are discussed. Copyright © 2016 Elsevier B.V.

  8. Proposed amendments to the legal proposition on establishment of non-marital paternity from 1855

    Full Text Available Proposed amendments to the article 130 of Serbian Civil Code (henceforth: SCC of 1844 regarding establishment of non-marital paternity were scrutinized in this paper. Originally, establishment of non-marital paternity was granted, but with significant restriction that presumed parent could have been declared the father of an illegitimate child only if he had recognized paternity. That is the reason why in 1855 the Supreme Court suggested amendment to the provision concerning determination of paternity. According to proposed modification, evidence that presumed father was on intimate terms with child's mother in the time of conception should have been sufficient for establishment of paternity. As non-marital relationships were condemned in patriarchal Serbian 19th century society, illegitimate children were considered a product of sin and family disgrace. Hence, the Ministry of Justice, the State Council and Prince Aleksandar Karađorđević were not interested in bettering their position by widening possibilities of determination of fatherhood. Subsequently, in 1868 the amendment was passed by which non-marital paternity could not have been established by a court order, subject to certain exceptions (if one raped or abducted a woman, and the time of conception coincided with the time of abduction or rape. Since 1868 paternity could have been determined solely subject to the consent, i.e. recognition of the illegitimate father.

    Structural factors associated with public housing contribute to living environments that expose families to adverse life events that may in turn directly impact parenting and youth outcomes. However, despite the growth in research on fathers, research on families in public housing has practically excluded fathers and the role fathers play in the well-being of their adolescents. Using a sample of 660 African American adolescents recruited from public housing, we examined the relationship between paternal caregivers' (i.e., fathers' and father figures') parenting practices and adolescents' depressive symptoms, attitudes toward deviance, and self-efficacy. Using a latent profile analysis (LPA), we confirmed a four-class model of paternal parenting practices ranging from high to low levels of monitoring and encouragement. Results from a one-way ANOVA indicated that paternal caregivers with high (compared to moderate) levels of encouragement and monitoring were associated with youth who reported less depressive symptoms, higher levels of self-efficacy, and less favorable attitudes toward deviance. Discriminant analysis results indicated that approximately half of the sample were correctly classified into two paternal caregiver classes. The findings provide evidence that some of these caregivers engage in parenting practices that support youths' psychological functioning. More research is needed to determine what accounts for the variability in levels of paternal encouragement and supervision, including environmental influences, particularly for paternal caregivers exhibiting moderate-to-low levels of paternal encouragement and monitoring. © 2016 Family Process Institute.

  10. Shadows of doubt: the uneasy incorporation of identification science into legal determination of paternity in Brazil

    Full Text Available The arrival of DNA paternity testing in the 1980s was met with great enthusiasm in the Brazilian courts. Yet, over the past two decades, Brazilian legal doctrine and jurisprudence have increasingly rejected DNA proof as the sine qua non for paternity cases. Instead, DNA paternity testing has generated mountains of litigation, as biological proof has been challenged by the argument that paternity is primarily “socio-affective”. Leading family law specialists describe this new conception of paternity as an outcome of the “revolutionary” provisions of the 1988 Constitution, which recognizes the “pluralism” of family forms in modern society and guarantees equal family rights for all children. Without denying the significance of the constitution’s dignitary framework, we show that new legal understandings of paternity represent less a paradigm shift than a continuation of longstanding historical tensions between biological and socio-cultural understandings of family and identity. In this article, we explore the development of biological and eventually genetic typing in Brazil, both of which had ties to the fields of criminology and race science. Our review suggests that techniques of biological identification, no matter how sophisticated or precise, were ineffective means for establishing identity, whether of individual personhood, as in the case of paternity, or national make-up. Instead, they became incorporated as supplemental methods into complex legal, social, and cultural decision-making around families.

    Maternal psychopathology robustly predicts poor developmental and treatment outcomes for children with attention-deficit/hyperactivity disorder (ADHD). Despite the high heritability of ADHD, few studies have examined associations between paternal ADHD symptoms and child adjustment, and none have also considered degree of paternal involvement in childrearing. Identification of modifiable risk factors for child conduct problems is particularly important in this population given the serious adverse outcomes resulting from this comorbidity. This cross-sectional study examined the extent to which paternal involvement in childrearing moderated the association between paternal ADHD symptoms and child conduct problems among 37 children with ADHD and their biological fathers. Neither paternal ADHD symptoms nor involvement was independently associated with child conduct problems. However, the interaction between paternal ADHD symptoms and involvement was significant, such that paternal ADHD symptoms were positively associated with child conduct problems only when fathers were highly involved in childrearing. The presence of adult ADHD symptoms may determine whether father involvement in childrearing has a positive or detrimental influence on comorbid child conduct problems.

  15. Patterns of paternity skew among polyandrous social insects: what can they tell us about the potential for sexual selection?

    Monogamy results in high genetic relatedness among offspring and thus it is generally assumed to be favored by kin selection. Female multiple mating (polyandry) has nevertheless evolved several times in the social Hymenoptera (ants, bees, and wasps), and a substantial amount of work has been conducted to understand its costs and benefits. Relatedness and inclusive fitness benefits are, however, not only influenced by queen mating frequency but also by paternity skew, which is a quantitative measure of paternity biases among the offspring of polyandrous females. We performed a large-scale phylogenetic analysis of paternity skew across polyandrous social Hymenoptera. We found a general and significant negative association between paternity frequency and paternity skew. High paternity skew, which increases relatedness among colony members and thus maximizes inclusive fitness gains, characterized species with low paternity frequency. However, species with highly polyandrous queens had low paternity skew, with paternity equalized among potential sires. Equal paternity shares among fathers are expected to maximize fitness benefits derived from genetic diversity among offspring. We discuss the potential for postcopulatory sexual selection to influence patterns of paternity in social insects, and suggest that sexual selection may have played a key, yet overlooked role in social evolution. © 2012 The Author(s).

  17. Adoptive paternal age and risk of psychosis in adoptees: a register based cohort study.

    Mats Ek

    Full Text Available The association between advancing paternal age and increased risk of schizophrenia in the off-spring is well established. The underlying mechanisms are unknown. In order to investigate whether the psychosocial environment associated with growing up with an aged father explains the increased risk we conducted a study of all adoptive children in Sweden from 1955-1985 (n =31 188. Their risk of developing schizophrenia or non-affective psychosis in relation to advancing age of their adoptive fathers' was examined. We found no association between risk of psychoses and advancing adoptive paternal age. There was no support of psychosocial environmental factors explaining the "paternal age effect".

    A number of social, familial, and psychological factors have been identified to explain the onset of mood and anxiety disorders among adolescent and young adult populations. The purpose of this study is to identify the shared and unique predictors of anxiety and mood disorders by simultaneously testing a range of established psychosocial risk factors. A national birth cohort of the Danish population born in 1984 and tracked over the course of the first 21 years of their life was used in the current study (n = 54,458). Psychosocial risk factors including paternal and maternal history of any anxiety and mood disorder, parental history of self-harming behaviour, advanced paternal age, gender, urban dwelling, economic deprivation, family dissolution, and childhood adversity were used to predict diagnosis of both anxiety and mood disorders from ages 10 to 21 years. Binary logistic regression analysis showed that being female and a parental history of a mood or anxiety disorder are the strongest predictors of both disorders. Economic deprivation, and family dissolution also increase likelihood of both disorders. Urban dwelling and childhood adversity are predictors of anxiety disorders but not mood disorders. Between the ages of 10 and 21 years, anxiety and mood disorders share many common risk factors. However, urban dwelling and childhood adversity appear to be unique predictors of anxiety disorders. Results suggest there is no dominant factor in the prediction of either disorder, rather the accumulation of different risk factors is most deleterious.

  19. Emotional reasoning and anxiety sensitivity: associations with social anxiety disorder in childhood.

    2014-01-01

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

    There is increasing interest in the co-occurrence of social anxiety and addiction. Each investigation has a specific vantage point, e.g., the effect social anxiety has in a population with addiction or that of addiction in a population with social anxiety, which could create unique findings. Among comorbid individuals, is social anxiety more severe in people seeking treatment for anxiety, as compared to those seeking treatment for addiction? This report compares social anxiety severity between subjects in two studies--one involving socially anxious individuals (n=38) seeking treatment for addictions; the other (n=41) subjects with social anxiety and an alcohol use disorder, seeking treatment for social anxiety. Baseline severity scores on the Liebowitz Social Anxiety Scale for social anxiety were compared between the groups. No significant differences were found. For both groups, social anxiety was largely in the severe range. The results suggest that clinicians should attend to social anxiety symptom severity in patients with co-occurring social anxiety and addiction, regardless of the condition for which treatment is sought.

  1. The nature of social anxiety disorder.

    Westenberg, H G

    1998-01-01

    The essential feature of social anxiety disorder (social phobia) is a fear of scrutiny by other people in social or performance situations. The level of anxiety experienced by the person with social anxiety disorder is excessive, and results in substantial impairment in the sufferer's social, family, and professional life. Three distinct subtypes of the disorder have been identified: generalized social anxiety disorder, in which the individual fears a multitude of social situations; nongeneralized social anxiety disorder, in which only 2 or 3 situations are feared; and public-speaking phobia. Results from a number of studies suggest that these subtypes of social anxiety disorder may represent distinct clinical syndromes, with the generalized subtype producing the most severe disability. Despite the prevalence of social anxiety disorder and the disability it causes, this condition remains underdiagnosed, and thus undertreated, by clinicians. This review discusses the barriers that prevent people who have this disorder from seeking help, and the steps that clinicians can take to aid their recognition and treatment of the disorder. It is only by effective diagnosis and treatment that the burden of social anxiety disorder will be lifted, allowing patients to resume a normal life.

  2. Pharmacologic Treatment of Pediatric Anxiety Disorders.

    2016-06-01

    The last decade has seen considerable advances in the treatment of anxiety disorders in children and adolescents and a considerable expansion of the evidence base for psychopharmacologic in this population. The extant data suggest that, for fear-based anxiety disorders ( e.g. , generalized anxiety disorder, social phobia/social anxiety disorder, and separation anxiety disorder), selective serotonin reuptake inhibitors (SSRIs) and selective serotonin norepinephrine reuptake inhibitors (SSNRIs) are well tolerated and offer considerable benefit. However, the salutary effects of SSRIs and SSNRIs in pediatric anxiety disorders are consistently amplified by the addition of psychotherapy, particularly in individuals with social anxiety disorder. Additionally, several key demographic and clinical factors, including male sex, non-minority status, and better family functioning and younger age predict greater symptomatic improvement in youth with fear-based anxiety disorders. Thus, current data suggest that in addition to several forms of psychotherapy, including cognitive-behavioral therapy (CBT), SSRIs and SSNRIs are efficacious in the treatment of these conditions in youth and that CBT + an SSRI may be associated with greater improvement than would be expected with either treatment as monotherapy. Finally, given that some children and adolescents may exhibit partial response to current pharmacotherapies, benzodiazepines, anti-histamines and other agents may have adjunctive roles, despite a lack of data in terms of large, randomized controlled trials.

    Stress and chronically elevated glucocorticoid levels have been shown to disrupt parental behavior in mothers; however, almost no studies have investigated corresponding effects in fathers. The present experiment tested the hypothesis that chronic variable stress inhibits paternal behavior and consequently alters pup development in the monogamous, biparental California mouse (Peromyscus californicus). First-time fathers were assigned to one of three experimental groups: chronic variable stress (CVS, n=8), separation control (SC, n=7), or unmanipulated control (UC, n=8). The CVS paradigm (3 stressors per day for 7 days) successfully stressed mice, as evidenced by increased baseline plasma corticosterone concentrations, increased adrenal mass, decreased thymus mass, and a decrease in body mass over time. CVS altered paternal and social behavior of fathers, but major differences were observed only on day 6 of the 7-day paradigm. At that time point, CVS fathers spent less time with their pairmate and pups, and more time autogrooming, as compared to UC fathers; SC fathers spent more time behaving paternally and grooming the female mate than CVS and UC fathers. Thus, CVS blocked the separation-induced increase in social behaviors observed in the SC fathers. Nonetheless, chronic stress in fathers did not appear to alter survival or development of their offspring: pups from the three experimental conditions did not differ in body mass gain over time, in the day of eye opening, or in basal or post-stress corticosterone levels. These results demonstrate that chronic stress can transiently disrupt paternal and social behavior in P. californicus fathers, but does not alter pup development or survival under controlled, non-challenging laboratory conditions. © 2013.

  5. Social anxiety, stress type, and conformity among adolescents

    2016-05-01

    Full Text Available Social anxiety and stress type can influence strong conformity among adolescents; however, the interaction between them is not clear. In this study, 152 adolescents were recruited and assigned one of two conditions: an interaction and a judgment condition. In the interaction condition, adolescents with high social anxiety were less likely to conform when completing a modified Asch task, compared to adolescents who had low social anxiety. In the judgment condition, adolescents with high social anxiety were more likely to conform to the opinions from the unanimous majority. The results suggest that adolescents with high social anxiety may show different styles of strong conformity with the change of stress type. We believe that socially anxious adolescents avoid potential social situations with weaker conformity, while avoiding negative evaluations from others with stronger conformity. These findings contribute to a better understanding of the social dysfunctions among adolescents with high social anxiety and provide a new direction for clinical interventions.

    This investigation examined the effects of relaxing music for anxiety control on measures of competitive state anxiety and the performance of a simple motor skill. Seventy-two undergraduate students volunteered to participate in the study. Participants were informed that they would be required to partake in a sport competition, possibly with an audience present, and possibly whilst being filmed. Participants were randomly allocated to one of three intervention conditions, listening to relaxing music for anxiety control, listening to non-relaxing music or a no music control. During the 10-minute intervention period, measures of anxiety (CSAI-2R, subjective relaxation and HR) were taken on three occasions (baseline, pre-intervention and post-intervention). Repeated measures MANOVA showed that all three interventions provoked significant reductions in competitive state anxiety. Condition had no impact upon any of the DVs. These results suggest that listening to relaxing music for anxiety control was no more effective at reducing competitive state anxiety than non-relaxing music or a period of silence. ES, mean difference and 90% CI data did however provide some support for the application of relaxing music for anxiety control. There were no between-condition differences in motor task performance.

  7. The observed human sperm mutation frequency cannot explain the achondroplasia paternal age effect

    2002-01-01

    The lifelong spermatogonial stem cell divisions unique to male germ cell production are thought to contribute to a higher mutation frequency in males. The fact that certain de novo human genetic conditions (e.g., achondroplasia) increase in incidence with the age of the father is consistent with this idea. Although it is assumed that the paternal age effect is the result of an increasing frequency of mutant sperm as a man grows older, no direct molecular measurement of the germ-line mutation frequency has been made to confirm this hypothesis. Using sperm DNA from donors of different ages, we determined the frequency of the nucleotide substitution in the fibroblast growth factor receptor 3 (FGFR3) gene that causes achondroplasia. Surprisingly, the magnitude of the increase in mutation frequency with age appears insufficient to explain why older fathers have a greater chance of having a child with this condition. A number of alternatives may explain this discrepancy, including selection for sperm that carry the mutation or an age-dependent increase in premutagenic lesions that remain unrepaired in sperm and are inefficiently detected by the PCR assay.

  9. Beyond Boys' Bad Behavior: Paternal Incarceration and Cognitive Development in Middle Childhood.

    2016-12-07

    A growing number of American school-aged children have incarcerated or formally incarcerated parents necessitating a more comprehensive understanding of the intergenerational effects of mass imprisonment. Using the Fragile Families Study, I assess whether having an incarcerated father impacts children's cognitive skill development into middle childhood. While previous studies have primarily found effects for boys' behavior problems, matching models and sensitivity analyses demonstrate that experiencing paternal incarceration by age 9 is associated with lower cognitive skills for both boys and girls and these negative effects hold net of a pre-paternal incarceration measure of child cognitive ability. Moreover, I estimate that paternal incarceration explains between 2 and 15 percent of the Black-White achievement gap at age 9. These findings represent new outcomes of importance and suggest that paternal incarceration may play an even larger role in the production of intergenerational inequalities for American children than previously documented.

    A possible detrimental paternal age effect on offspring health due to mutations of paternal origin should be reflected in an association between paternal age and fetal loss. The authors used data from a prospective study of 23,821 pregnant women recruited consecutively to the Danish National Birth...... analysis. Pregnancies fathered by a man aged 50 or more years (n = 124) had almost twice the risk of ending in a fetal loss compared with pregnancies with younger fathers (hazard ratio = 1.88, 95% confidence interval: 0.93, 3.82), after adjustment for maternal age, reproductive history, and maternal...... lifestyle during pregnancy. Various approaches to adjustment for potential residual confounding of the relation by maternal age did not affect the relative risk estimates. The paternal age-related risk of late fetal death was higher than the risk of early fetal death and started to increase from the age...

    1996-11-01

    The analysis of genetic markers in man allows to efficiently resolve cases of dubious paternity. Lately, the use of genetic markers derived from DNA analysis allows high exclusion probabilities. A particular case are those consultations whom the progenitors are closely related, in which the criteria to attribute paternity are modified. The present report explains the analysis methods and interpretation of results in situations of doubtful paternity in cases of incest between father and daughter, using monolocus DNA polymorphisms. The method is illustrated through the analysis of four cases seen at the Servicio Médico Legal of Santiago. To be able to determine paternity in these cases of incest, at least three multiallelic loci in which mother and son have different genotypes must be examined.

    2010-01-01

    Polygyny and extra-pair paternity are generally thought to enhance sexual selection. However, the extent to which these phenomena increase variance in male reproductive success will depend on the covariance between success at these two strategies. We analysed these patterns over four breeding seasons in facultatively polygynous blue tits Cyanistes caeruleus. We found that both polygyny and extra-pair paternity increased variance in male reproductive success and that standardised variance in a...

  16. The degree of extra-pair paternity increases with genetic variability

    OpenAIRE

    1998-01-01

    The amount of extra-pair paternity in socially monogamous bird species varies from 0% to 76% extra-pair offspring. The causes of this remarkable interspecific variation are largely unknown, although intraspecific analyses suggest that females seek extra-pair matings to improve the genetic quality of their offspring. If this is a general explanation for the occurrence of extra-pair matings, then proportionally more females should seek to modify the paternity of their clutch when there is more ...

    Few studies have examined the relationship between paternal stimulation and children's growth and development, particularly in low- and middle-income countries (LMICs). This study aimed to estimate the prevalence of paternal stimulation and to assess whether paternal stimulation was associated with early child growth and development. Data from the Multiple Indicator Cluster Surveys rounds 4 and 5 were combined across 38 LMICs. The sample comprised 87 286 children aged 3 and 4 years. Paternal stimulation was measured by the number of play and learning activities (up to 6) a father engaged in with his child over the past 3 days. Linear regression models were used to estimate standardized mean differences in height-for-age z-scores and Early Childhood Development Index (ECDI) z-scores across 3 levels of paternal stimulation, after controlling for other caregivers' stimulation and demographic covariates. A total of 47.8% of fathers did not engage in any stimulation activities, whereas 6.4% of fathers engaged in 5 or 6 stimulation activities. Children whose fathers were moderately engaged in stimulation (1-4 activities) showed ECDI scores that were 0.09 SD (95% confidence interval [CI]: -0.12 to -0.06) lower than children whose fathers were highly engaged; children whose fathers were unengaged showed ECDI scores that were 0.14 SD lower (95% CI: -0.17 to -0.12). Neither moderate paternal stimulation nor lack of paternal stimulation was associated with height-for-age z-scores, relative to high stimulation. Increasing paternal engagement in stimulation is likely to improve early child development in LMICs. Copyright © 2016 by the American Academy of Pediatrics.

    BACKGROUND AND OBJECTIVE: To date, most parent-based research has neglected the role of fathers in shaping adolescent sexual behavior and has focused on mothers. The objective of this study was to conduct a structured review to assess the role of paternal influence on adolescent sexual behavior and to assess the methodological quality of the paternal influence literature related to adolescent sexual behavior. METHODS: We searched electronic databases: PubMed, PsychINFO, Social Services Abstracts, Family Studies Abstracts, Sociological Abstracts, and the Cumulative Index to Nursing and Allied Health Literature. Studies published between 1980 and 2011 that targeted adolescents 11 to 18 years and focused on paternal parenting processes were included. Methodological quality was assessed by using an 11-item scoring system. RESULTS: Thirteen articles were identified and reviewed. Findings suggest paternal factors are independently associated with adolescent sexual behavior relative to maternal factors. The most commonly studied paternal influence was emotional qualities of the father-adolescent relationship. Paternal communication about sex was most consistently associated with adolescent sexual behavior, whereas paternal attitudes about sex was least associated. Methodological limitations include a tendency to rely on cross-sectional design, nonprobability sampling methods, and focus on sexual debut versus broader sexual behavior. CONCLUSIONS: Existing research preliminarily suggests fathers influence the sexual behavior of their adolescent children; however, more rigorous research examining diverse facets of paternal influence on adolescent sexual behavior is needed. We provide recommendations for primary care providers and public health practitioners to better incorporate fathers into interventions designed to reduce adolescent sexual risk behavior.

    Full Text Available Anxiety disorders and medical illness present to the primary care physician as a common comorbidity. This article aims to review the literature on the prevalence of anxiety disorders in patients presenting to primary care physicians; to address the key issues in assessing the comorbid condition; and to discuss psychological and pharmacological treatment options for patients with a comorbid anxiety disorder and medical illness. Anxiety disorders are highly prevalent within the primary care population, and these disorders significantly impact the patient′s course and outcome. Fortunately, primary care physicians have a variety of effective cognitive, behavioral and pharmacological interventions available for managing these patients with comorbid anxiety and medical illnesses.

    Full Text Available The present study examined the relative prediction and joint effects of maternal and paternal psychological control on children’s socioemotional development. A total of 325 preschool children between the ages of 34 and 57 months (M = 4 years 2 months and their parents participated in the study. Fathers and mothers, respectively, reported their levels of psychological control and mothers evaluated the socioemotional development of children using two indicators (i.e., behavioral problems and prosocial behaviors. The results indicated that the relative predictive effects of maternal and paternal psychological control on children’s socioemotional development differed. Specifically, maternal psychological control was a significant predictor of children’s behavioral problems and prosocial behaviors, whereas the levels of paternal psychological control were unrelated to children’s socioemotional development. With regard to the combined effects of maternal and paternal psychological control, the results of ANOVAs and simple slope analysis both indicated that children would be at risk of behavioral problems as long as they had one highly psychologically controlling parent. High levels of paternal psychological control were associated with increased behavioral problems of children only when maternal psychological control was low. However, the association between maternal psychological control and children’s behavioral behaviors was significant, despite paternal psychological control.

  1. Implications of advancing paternal age: does it affect offspring school performance?

    Full Text Available Average paternal age is increasing in many high income countries, but the implications of this demographic shift for child health and welfare are poorly understood. There is equivocal evidence that children of older fathers are at increased risk of neurodevelopmental disorders and reduced IQ. We therefore report here on the relationship between paternal age and a composite indicator of scholastic achievement during adolescence, i.e. compulsory school leaving grades, among recent birth cohorts in Stockholm County where delayed paternity is notably common. We performed a record-linkage study comprising all individuals in Stockholm County who finished 9 years of compulsory school from 2000 through 2007 (n = 155,875. Data on school leaving grades and parental characteristics were retrieved from administrative and health service registers and analyzed using multiple linear regression. Advancing paternal age at birth was not associated with a decrease in school leaving grades in adolescent offspring. After adjustment for year of graduation, maternal age and parental education, country of birth and parental mental health service use, offspring of fathers aged 50 years or older had on average 0.3 (95% CI -3.8, 4.4 points higher grades than those of fathers aged 30-34 years. In conclusion, advancing paternal age is not associated with poorer school performance in adolescence. Adverse effects of delayed paternity on offspring cognitive function, if any, may be counterbalanced by other potential advantages for children born to older fathers.

  2. Higher levels of multiple paternities increase seedling survival in the long-lived tree Eucalyptus gracilis.

    Directory of Open Access Journals (Sweden)

    Martin F Breed

    Full Text Available Studying associations between mating system parameters and fitness in natural populations of trees advances our understanding of how local environments affect seed quality, and thereby helps to predict when inbreeding or multiple paternities should impact on fitness. Indeed, for species that demonstrate inbreeding avoidance, multiple paternities (i.e. the number of male parents per half-sib family should still vary and regulate fitness more than inbreeding--named here as the 'constrained inbreeding hypothesis'. We test this hypothesis in Eucalyptus gracilis, a predominantly insect-pollinated tree. Fifty-eight open-pollinated progeny arrays were collected from trees in three populations. Progeny were planted in a reciprocal transplant trial. Fitness was measured by family establishment rates. We genotyped all trees and their progeny at eight microsatellite loci. Planting site had a strong effect on fitness, but seed provenance and seed provenance × planting site did not. Populations had comparable mating system parameters and were generally outcrossed, experienced low biparental inbreeding and high levels of multiple paternity. As predicted, seed families that had more multiple paternities also had higher fitness, and no fitness-inbreeding correlations were detected. Demonstrating that fitness was most affected by multiple paternities rather than inbreeding, we provide evidence supporting the constrained inbreeding hypothesis; i.e. that multiple paternity may impact on fitness over and above that of inbreeding, particularly for preferentially outcrossing trees at life stages beyond seed development.

    Paternal age at conception has been found to predict the number of new genetic mutations. We examined the effect of father’s age at birth on offspring intelligence, head circumference and personality traits. Using the Minnesota Twin Family Study sample we tested paternal age effects while controlling for parents’ trait levels measured with the same precision as offspring’s. From evolutionary genetic considerations we predicted a negative effect of paternal age on offspring intelligence, but not on other traits. Controlling for parental intelligence (IQ) had the effect of turning an initially positive association non-significantly negative. We found paternal age effects on offspring IQ and Multidimensional Personality Questionnaire Absorption, but they were not robustly significant, nor replicable with additional covariates. No other noteworthy effects were found. Parents’ intelligence and personality correlated with their ages at twin birth, which may have obscured a small negative effect of advanced paternal age (intelligence. We discuss future avenues for studies of paternal age effects and suggest that stronger research designs are needed to rule out confounding factors involving birth order and the Flynn effect.

    Full Text Available During hypoxia conditions, psychological states can be worsened. However, little information is available regarding the effect of physical exercise performed in hypoxia conditions on mood state and anxiety symptoms. The aim of the present study was to elucidate the acute effect of moderate physical exercise performed at hypoxia on mood states and anxiety symptoms in healthy young subjects. Ten volunteers were subjected to the following conditions: a normoxic condition (NC and a hypoxic condition (HC. They performed 45 min of physical exercise. Their anxiety symptoms and mood states were evaluated at the initial time point as well as immediately following and 30 and 60 min after the exercise session. Our results showed a significant increase in post-exercise anxiety symptoms and a significant decrease in mood scores immediately after and 30 min after exercise performed in the HC. Moderate physical activity performed at hypoxia condition increased post-exercise anxiety and worsened mood state.

  6. The paternal function in Winnicott: the psychoanalytical frame.

    2014-08-01

    My first aim has been to identify the implicit assumptions underlying Winnicott's detailed notes on a fragment of an analysis dating from 1955 and published after his death. The importance given by Winnicott to the father figure as early as 1955 is one of my discoveries; another is the deep Freudian roots of his thinking. In this essay I propose a new way of linking together the concepts of 'paternal function' and the 'psychoanalytical frame'. Developing my hypothesis, I compare my reading of Winnicott and my way of reading José Bleger's study on the frame. Like Winnicott, I explore in detail a process of discovery, focusing on what the analyst and the patient are nor fully aware of …'as yet'. I am not proposing to unify Winnicott's and Bleger's thinking. My aim is to avoid the pitfall of eclecticism and, in so doing, to recognize both the related depths they sound in their thinking and their otherness. I want to share with the readers their 'meeting' in my mind. Copyright © 2014 Institute of Psychoanalysis.

  7. Maternal and Paternal Height and the Risk of Preeclampsia.

    2018-04-01

    The etiology of preeclampsia is unknown. Tall women have been found to have lower incidence of preeclampsia. This points to a possible biological causal effect but may be because of socioeconomic confounding. We used paternal height as an unexposed control to examine confounding. The MoBa (Norwegian Mother and Child Cohort Study) was used to extract data on parental heights, maternal prepregnancy weight, other background factors, and pregnancy outcomes for 99 968 singleton births. Multiple logistic regression was used to estimate odds ratios for preeclampsia according to parental height. The adjusted odds ratio for preeclampsia was 0.74 (95% CI, 0.66-0.82) for women >172 cm as compared with women 186 cm was 1.03 (95% CI, 0.93-1.15) compared with men <178 cm. The association between maternal height and preeclampsia is unlikely to be because of confounding by familial, socioeconomic factors or by fetal genes related to height. The observed association between maternal height and preeclampsia merits further investigation. © 2018 American Heart Association, Inc.

  8. Paternalism and utilitarianism in research with human participants.

    Science.gov (United States)

    Resnik, David B

    2015-03-01

    In this article I defend a rule utilitarian approach to paternalistic policies in research with human participants. Some rules that restrict individual autonomy can be justified on the grounds that they help to maximize the overall balance of benefits over risks in research. The consequences that should be considered when formulating policy include not only likely impacts on research participants, but also impacts on investigators, institutions, sponsors, and the scientific community. The public reaction to adverse events in research (such as significant injury to participants or death) is a crucial concern that must be taken into account when assessing the consequences of different policy options, because public backlash can lead to outcomes that have a negative impact on science, such as cuts in funding, overly restrictive regulation and oversight, and reduced willingness of individuals to participate in research. I argue that concern about the public reaction to adverse events justifies some restrictions on the risks that competent, adult volunteers can face in research that offers them no significant benefits. The paternalism defended here is not pure, because it involves restrictions on the rights of investigators in order to protect participants. It also has a mixed rationale, because individual autonomy may be restricted not only to protect participants from harm but also to protect other stakeholders. Utility is not the sole justification for paternalistic research policies, since other considerations, such as justice and respect for individual rights/autonomy, must also be taken into account.

    Personality features have been correlated with suicidal behaviors in recent decades. Given its neurobiological background, Cloninger's model of personality, the Temperament and Character Inventory (TCI), may help to identify the maternal and paternal personality dimensions associated with adolescent suicide attempts. The present study is the first that specifically compares the temperament and character profiles of both mothers and fathers of the adolescent suicide attempters with a control group, by considering the influence of demographic and clinical factors. The study group comprised 117 parents of 71 adolescent suicide attempters and 119 parents of 71 age- and gender-matched adolescents without a suicide attempt included as a control group. The TCI and Brief Symptom Inventory (BSI) were applied to the parents in both groups. Logistic regression analysis, which was performed to adjust confounding factors, demonstrated significantly higher scores for harm avoidance among the mothers and lower scores of self-directedness among the fathers of the adolescent suicide attempters. New psychotherapeutic modalities considering the high-risk parental personality traits would be beneficial to support parent-adolescent relationships and may have a preventative effect on adolescent suicide.

  10. Rational suicide, assisted suicide, and indirect legal paternalism.

    Science.gov (United States)

    Schramme, Thomas

    2013-01-01

    This article argues in favour of three related claims: First, suicide is not an immoral act. If people autonomously choose to kill themselves, this ought to be respected. Second, we can deem the desire to die comprehensible, and even rational, when the person contemplating suicide does not see a meaning in her life. This assessment is not based on a metaphysically dubious comparison between the actual life of a person and the supposed state of being dead. Third, from the first two theses it does not automatically follow that we should allow other people to help someone who autonomously and rationally chooses to die to pursue this plan. To argue against indirect legal paternalism, the practice of legally preventing someone else to assist a person to perform a suicide or to be killed on request, needs additional reasons. It is argued that assisted suicide and voluntary active euthanasia can indeed be justified by establishing a claim of persons who want to die but are not able to kill themselves. This mainly means that being really free to die should be interpreted as involving the means to fulfil one's desire to die. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available For a long period of time pigs as farm animals were considered producing a single ware, pork. Not very long ago the pork market became interested in lean meet. Some breeders tried to have it from the old breeds and lave a lent genetic progress. Other breeders decided to follow the hybridization schemes used in poultry to produce broilers. But in strains with high daily gain and gross muscles the sows fertility declined and by then by disjunction selection they have isolated strains of high fertility. Then the final animal for the market was the cross piglet obtained from these two kinds of strains or lines. The third kind of breeders decided to specializing breeds, selected for as much as possible muscle mass as paternal breeds and breeds specialized for high fertility as maternal breeds. The present paper will present the movement taking place in the genealogy of a breed nucleus of 200sows with closed reproduction. The goal of the families’ movement analysis is to find out how to ensure a convenient genealogy structure preventing consanguinity when some families are extinct by selection for daily gain.

    2014-02-01

    Cass Sunstein and Richard Thaler have been arguing for what they named libertarian paternalism (henceforth LP). Their proposal generated extensive debate as to how and whether LP might lead down a full-blown paternalistic slippery slope. LP has the indubitable merit of having hardwired the best of the empirical psychological and sociological evidence into public and private policy making. It is unclear, though, to what extent the implementation of policies so constructed could enhance the capability for the exercise of an autonomous citizenship. Sunstein and Thaler submit it that in most of the cases in which one is confronted with a set of choices, some default option must be picked out. In those cases whoever devises the features of the set of options ought to rank them according to the moral principle of non-maleficence and possibly to that of beneficence. In this paper we argue that LP can be better implemented if there is a preliminary deliberative debate among the stakeholders that elicits their preferences, and makes it possible to rationally defend them.

  13. Autonomy and paternalism in medical e-commerce.

    Science.gov (United States)

    Mendoza, Roger Lee

    2015-08-01

    One of the overriding interests of the literature on health care economics is to discover where personal choice in market economies end and corrective government intervention should begin. Our study addresses this question in the context of John Stuart Mill's utilitarian principle of harm. Our primary objective is to determine whether public policy interventions concerning more than 35,000 online pharmacies worldwide are necessary and efficient compared to traditional market-oriented approaches. Secondly, we seek to determine whether government interference could enhance personal  utility maximization, despite its direct and indirect (unintended) costs on medical e-commerce. This study finds that containing the negative externalities of medical e-commerce provides the most compelling raison d'etre of government interference. It asserts that autonomy and paternalism need not be mutually exclusive, despite their direct and indirect consequences on individual choice and decision-making processes. Valuable insights derived from Mill's principle should enrich theory-building in health care economics and policy.

    Childhood experiences are thought to predispose a person to the development of health anxiety later in life. However, there is a lack of research investigating the influence of specific adverse experiences (e.g., childhood abuse, household dysfunction) on this condition. The current study examined the cumulative influence of multiple types of childhood adversities on health anxiety in adulthood. Adults 18-59 years of age (N=264) completed a battery of measures to assess adverse childhood experiences, health anxiety, and associated constructs (i.e., negative affect and trait anxiety). Significant associations were observed between adverse childhood experiences, health anxiety, and associated constructs. Hierarchical multiple regression analysis indicted that adverse childhood experiences were predictive of health anxiety in adulthood; however, the unique contribution of these experience were no longer significant following the inclusion of the other variables of interest. Subsequently, mediation analyses indicated that both negative affect and trait anxiety independently mediated the relationship between adverse childhood experiences and health anxiety in adulthood. Increased exposure to adverse childhood experiences is associated with higher levels of health anxiety in adulthood; this relationship is mediated through negative affect and trait anxiety. Findings support the long-term negative impact of cumulative adverse childhood experiences and emphasize the importance of addressing negative affect and trait anxiety in efforts to prevent and treat health anxiety.

    The emotional consequences of fatherhood are markedly conditional on the context in which fatherhood is lived out. This study examines the association between different contemporary forms of fatherhood and paternal psychological well-being. The data are from an anonymous online survey of 3615 biological fathers, stepfathers, adoptive fathers, and foster fathers across the German-speaking countries of Central Europe. First, a detailed characterization of the different existing family constellations is provided. Second, the consequences of these different contemporary forms of fatherhood for paternal psychological well-being are investigated. Fathers of all ages (M = 40.11, range: 19-72) with at least one child under the age of 18 were included in the present analysis (N = 2785). The presented findings demonstrate that a family structure consisting of two biological parents with biological children seems to be most beneficial to paternal well-being, while some other forms of contemporary fatherhood are associated with impaired well-being, independently of sociodemographic or relationship aspects. More specifically, a history of family separation in non-residential biological fathers and blended-family fathers, and the concomitant loss of father-child contact, is shown to be particularly disadvantageous for the well-being of these fathers. Shared living arrangements, maintaining regular contact with biological children, or forming a new intact family could protect these fathers from negative outcomes.

    2013-02-01

    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

    A considerable amount of children with anxiety disorders do not benefit sufficiently from cognitive behavioral treatment. The present study examines the predictive role of child temperament, parent temperament and parenting style in the context of treatment outcome. Participants were 145 children and adolescents (ages 8-18) with DSM-IV-TR anxiety disorders who received a 12-session CBT program and were assessed at pretreatment, posttreatment and three months follow-up. Multiple-regression analyses were used to evaluate the following pretreatment and posttreatment variables as potential predictors of treatment response at follow-up: baseline level of anxiety symptoms, child reported maternal and paternal rearing style (emotional warmth, rejection, and overprotection), parent reported child temperament traits (negative affect, effortful control, and extraversion), and mothers' and fathers' self-report temperament traits. More maternal negative affect and less emotional warmth as perceived by the child before treatment were related to less favorable treatment outcome (accounting for 29% of the variance in anxiety at follow-up). Furthermore, maternal negative affect and children's extraversion measured after treatment also predicted anxiety at follow-up (together accounting for 19% of the variance). Paternal temperament and parenting style were unrelated to treatment outcome, as were children's pretreatment temperament traits. The results suggest that tailoring intervention to include strategies to reduce maternal negative affect and promote an emotional warm rearing style may improve treatment outcome.

    Preliminary studies have implicated childhood exposure to parental problem drinking as a possible factor in the development of anxiety sensitivity (AS). The present retrospective study was designed to examine the role of exposure to distressing parental problem drinking behaviors, over and above the role of parental alcoholism, in the development of various AS components (psychological, physical, and social concerns) in the offspring. We also examined the possible mediating role of AS components in explaining relations between parental drinking problems and anxiety-related symptoms in the adult offspring. A sample of 213 university students provided retrospective reports of both distress related to parental drinking [Children of Alcoholics Screening Test (CAST)] and parental alcoholism [maternal and paternal forms of the Short Michigan Alcoholism Screening Test (SMAST)]. Participants also reported on their own current AS levels [AS Index (ASI)], general anxiety symptoms [State-Trait Anxiety Inventory-Trait subscale (STAI-T)], and lifetime history of uncued panic attacks [Panic Attack Questionnaire-Revised (PAQ-R)]. Scores on the CAST predicted AS psychological and physical concerns (but not social concerns) over and above participant gender and parental alcoholism measured by the SMASTs. Moreover, AS psychological concerns proved a consistent modest mediator of the relations between parental problem drinking on the CAST and both general anxiety and uncued panic outcomes in the offspring. Thus, exposure to distressing parental problem drinking behavior may be one factor that contributes to elevated AS psychological concerns in the child, which in turn may contribute to the development of anxiety disorder symptoms in the offspring.

  3. Sleep and anxiety disorders.

    2003-09-01

    Sleep disturbances-particularly insomnia - are highly prevalent in anxiety disorders and complaints such as insomnia or nightmares have even been incorporated in some anxiety disorder definitions, such as generalized anxiety disorder and posttraumatic stress disorder. In the first part of this review, the relationship between sleep and anxiety is discussed in terms of adaptive response to stress. Recent studies suggested that the corticotropin-releasing hormone system and the locus ceruleus-autonomic nervous system may play major roles in the arousal response to stress. It has been suggested that these systems may be particularly vulnerable to prolonged or repeated stress, further leading to a dysfunctional arousal state and pathological anxiety states, Polysomnographic studies documented limited alteration of sleep in anxiety disorders. There is some indication for alteration in sleep maintenance in generalized anxiety disorder and for both sleep initiation and maintenance in panic disorder; no clear picture emerges for obsessive-compulsive disorder or posttraumatic stress disorder. Finally, an unequivocal sleep architecture profile that could specifically relate to a particular anxiety disorder could not be evidenced; in contrast, conflicting results are often found for the same disorder. Discrepancies between studies could have been related to illness severity, diagnostic comorbidity, and duration of illness. A brief treatment approach for each anxiety disorder is also suggested with a special focus on sleep.

  4. The effect of multiple paternity on genetic diversity of small populations during and after colonisation.

    Full Text Available Genetic variation within and among populations is influenced by the genetic content of the founders and the migrants following establishment. This is particularly true if populations are small, migration rate low and habitats arranged in a stepping-stone fashion. Under these circumstances the level of multiple paternity is critical since multiply mated females bring more genetic variation into founder groups than single mated females. One such example is the marine snail Littorina saxatilis that during postglacial times has invaded mainland refuge areas and thereafter small islands emerging due to isostatic uplift by occasional rafting of multiply mated females. We modelled effects of varying degrees of multiple paternity on the genetic variation of island populations colonised by the founders spreading from the mainland, by quantifying the population heterozygosity during both the transient colonisation process, and after a steady state (with migration has been reached. During colonisation, multiple mating by [Formula: see text] males increased the heterozygosity by [Formula: see text] in comparison with single paternity, while in the steady state the increase was [Formula: see text] compared with single paternity. In the steady state the increase of heterozygosity due to multiple paternity is determined by a corresponding increase in effective population size. During colonisation, by contrast, the increase in heterozygosity is larger and it cannot be explained in terms of the effective population size alone. During the steady-state phase bursts of high genetic variation spread through the system, and far from the mainland this led to short periods of high diversity separated by long periods of low diversity. The size of these fluctuations was boosted by multiple paternity. We conclude that following glacial periods of extirpation, recolonization of isolated habitats by this species has been supported by its high level of multiple paternity.

    We sought to assess the impact of paternal involvement on adverse birth outcomes in teenage mothers. Using vital records data, we generated odds ratios (OR) and 95% confidence intervals (CI) to assess the association between paternal involvement and fetal outcomes in 192,747 teenage mothers. Paternal involvement status was based on presence/absence of paternal first and/or last name on the birth certificate. Data were obtained from vital records data from singleton births in Florida between 1998 and 2007. The study population consisted of 192,747 teenage mothers ≤ 20 years old with live single births in the State of Florida. Low birth weight, very low birth weight, preterm birth, very preterm birth, small for gestational age (SGA), neonatal death, post-neonatal death, and infant death. Risks of SGA (OR = 1.06; 95% CI: 1.03-1.10), low birth weight (OR = 1.19; 95% CI: 1.15-1.23), very low birth weight (OR = 1.53; 95% CI: 1.41-1.67), preterm birth (OR = 1.21; 95% CI: 1.17-1.25), and very preterm birth (OR = 1.49; 95% CI: 1.38-1.62) were elevated for mothers in the father-absent group. When results were stratified by race, black teenagers in the father-absent group had the highest risks of adverse birth outcomes when compared to white teenagers in the father-involved group. Lack of paternal involvement is a risk factor for adverse birth outcomes among teenage mothers; risks are most pronounced among African-American teenagers. Our findings suggest that increased paternal involvement can have a positive impact on birth outcomes for teenage mothers, which may be important for decreasing the racial disparities in infant morbidities. More studies assessing the impact of greater paternal involvement on birth outcomes are needed. Copyright © 2011 North American Society for Pediatric and Adolescent Gynecology.

  7. Paternity-parasitism trade-offs: a model and test of host-parasite cooperation in an avian conspecific brood parasite.

    Efforts to evaluate the evolutionary and ecological dynamics of conspecific brood parasitism in birds and other animals have focused on the fitness costs of parasitism to hosts and fitness benefits to parasites. However, it has been speculated recently that, in species with biparental care, host males might cooperate with parasitic females by allowing access to the host nest in exchange for copulations. We develop a cost-benefit model to explore the conditions under which such host-parasite cooperation might occur. When the brood parasite does not have a nest of her own, the only benefit to the host male is siring some of the parasitic eggs (quasi-parasitism). Cooperation with the parasite is favored when the ratio of host male paternity of his own eggs relative to his paternity of parasitic eggs exceeds the cost of parasitism. When the brood parasite has a nest of her own, a host male can gain additional, potentially more important benefits by siring the high-value, low-cost eggs laid by the parasite in her own nest. Under these conditions, host males should be even more likely to accept parasitic eggs in return for copulations with the parasitic female. We tested these predictions for American coots (Fulica americana), a species with a high frequency of conspecific brood parasitism. Multilocus DNA profiling indicated that host males did not sire any of the parasitic eggs laid in host nests, nor did they sire eggs laid by the parasite in her own nest. We used field estimates of the model parameters from a four-year study of coots to predict the minimum levels of paternity required for the costs of parasitism to be offset by the benefits of mating with brood parasites. Observed levels of paternity were significantly lower than those predicted under a variety of assumptions, and we reject the hypothesis that host males cooperated with parasitic females. Our model clarifies the specific costs and benefits that influence host-parasite cooperation and, more generally

  8. Seasonal effects on egg production and level of paternity in a natural population of a simultaneous hermaphrodite snail

    In a seasonal environment, the suitable time window for females to reproduce is restricted by both environmental conditions and the availability of males. In simultaneous hermaphrodites, which are female and male at the same time, selection on a trait that is solely beneficial for one sexual function cannot occur independently. Therefore, it is assumed that the optimal time window for reproduction is a compromise between the two sexual functions in simultaneous hermaphrodites, mediated by environmental conditions. We examined seasonal patterns of reproduction and the resulting paternity in a natural population of the simultaneously hermaphroditic land snail Arianta arbustorum. Adult and premature individuals (snails in a short protandric phase) were collected on four occasions over the entire active season. The snails were allowed to deposit eggs after which we assessed the level of paternity in their hatched offspring. Individuals mated throughout the reproductive season, whereas egg production – the major task of the female function – was restricted to the first half of the season. Snails collected in autumn were allowed to hibernate under laboratory conditions. As a result, we found that premature individuals began to mate late in the reproductive season, but did not start to produce eggs before emerging from hibernation. Our results demonstrate a temporal shift of reproductive activities; the egg production and oviposition occur mainly in the first half of the season, while sperm production and mating occur over the entire season. In subadult and adult snails, sperm obtained from several partners in the second part of the reproductive season are stored during hibernation for the fertilization of eggs in the successive years. These results extend our understanding of the influence of both natural and sexual selection on reproductive strategies in hermaphrodites. PMID:26306176

    No studies have specifically considered paternal understanding of menstruation. This study aimed to establish the degree of understanding of fathers of adolescent girls with menstrual symptoms relative to mothers. This is a cross-sectional survey-based study. Adolescent patients attending an outpatient gynaecology clinic for dysmenorrhoea and/or heavy menstrual bleeding (HMB) and their parents were invited to complete surveys. 60 surveys were completed (24/40 daughters, 20/40 mothers, 16/40 fathers). Surveys aimed to test parents' understanding of menstrual symptoms and potential medications, as well as fathers' concerns with their daughters' health. The fathers' knowledge of menstrual symptoms was poorer than mothers, although most knew HMB (93%) and mood swings (87%). Many parents answered 'don't know' or did not answer questions about potential consequences of medications, although parents were clearly concerned about side effects. Most fathers (80%) were open to discussing menstrual concerns with daughters; however, only 52% of daughters were open to such discussions. Of fathers, 80% felt sympathetic/concerned, 53% helpless and 13% frustrated when daughters were in pain. When asked about impacts, 93% of fathers (79% of mothers) were worried about their daughter's welfare and 60% (21%) about schooling. We present the first insight into fathers' knowledge of their daughters' menstrual health. Overall, parents have an incomplete picture of menstrual symptoms. Even in this cohort, which could be expected to be well informed due to their daughters' attendance at a tertiary hospital, it is clear that further knowledge would assist them caring for their daughters.

    Sudden Unexpected Infant Death (SUID) results in 3400 sleep-related deaths yearly in the United States, yet caregivers' compliance with safe sleep recommendations remains less than optimal. Paternal caregiver's attitudes toward infant safe sleep messages are largely unaddressed, despite established differences between female and male caregiver perceptions. This study aimed to explore the determinants of safe sleep practices among male caregivers. Focus groups were conducted in Arkansas with male caregivers of infants ages 2-12 months to discuss infant sleep routines, parental roles, sources for safe sleep information, and messaging suggestions for safe sleep promotion. The Health Belief Model of behavior change framed a moderator guide. Transcript-based analysis was used, and data were managed using HyperRESEARCH (version 2.8.3). The transcribed data were coded to identify significant themes. Ten focus groups were conducted with 46 participants. Inconsistent adherence to safe sleep practices was reported. Participants were more likely to describe safe location (57% of participants) and supine position behaviors (42%) than an uncluttered bed environment (26%). Caregivers acknowledged the importance of recommended safe sleep behavior, but admitted to unsafe practices, such as co-sleeping and unsafe daytime sleep. Lack of perceived risk, comfort, and/or resources, and disagreement among family members about safety practices were identified as barriers. Participants voiced concerns that current advertising portrays males as incompetent caregivers. Suggestions included portraying positive images of fathers and male caregivers acting to promote safety and the incorporation of statistics about the hazards of unsafe sleep to better engage fathers. Potential distribution venues included sporting events, home improvement and/or automotive stores, and social media from trusted sites (e.g. hospitals or medical professionals). Male caregivers demonstrate some knowledge base

  11. High phobic anxiety is related to lower leukocyte telomere length in women.

    Full Text Available Chronic psychological distress has been linked to shorter telomeres, an indication of accelerated aging. Yet, little is known about relations of anxiety to telomeres. We examined whether a typically chronic form of anxiety--phobic anxiety--is related to telomere length.Relative telomere lengths (RTLs in peripheral blood leukocytes were measured by quantitative real-time polymerase chain reaction among 5,243 women (aged 42-69 years who: were participants in the Nurses' Health Study; were controls in prior case-control studies of telomeres and disease, or randomly selected healthy participants in a cognitive function sub-study; had completed the Crown-Crisp phobic index proximal to blood collection. Adjusted least-squares mean RTLs (z-scores were calculated across phobic categories. Higher phobic anxiety was generally associated with lower RTLs (age-adjusted p-trend = 0.09; this association was similar after adjustment for confounders--paternal age-at-birth, smoking, body mass index (BMI and physical activity (p-trend = 0.15. Notably, a threshold was identified. Among women with Crown-Crisp<6 points, the multivariable-adjusted least-squares mean RTL z-score = 0.02 standard units; however, among the most phobic women (Crown-Crisp ≥ 6, the multivariable-adjusted least-squares mean RTL z-score = -0.09 standard units (mean difference = -0.10 standard units; p = 0.02. The magnitude of this difference was comparable to that for women 6 years apart in age. Finally, effect modification by BMI, smoking and paternal age was observed: associations were stronger among highly phobic women with BMI ≥ 25 kg/m(2, without smoking history, or born to fathers aged ≥ 40 years.In this large, cross-sectional study high phobic anxiety was associated with shorter telomeres. These results point toward prospective investigations relating anxiety to telomere length change.

    This paper conceptualises organisational diversity as constituted by psychoanalytic lack. Empirically, we show how diversity as Lacanian lack is understood as nothing in or of itself, but as an empty signifier with no signified. The lack of diversity becomes a catalyst for desiring particular ideas...... of diversity that, however, constantly change due to the empty form of diversity. Anxiety manifests itself in the obsession of unobtainable idealised forms of diversity as well as in the uncertainty associated with the traumatic experience of always falling short of what is desired in an object...... – the experience of failed diversity. Conclusively, we discuss the productive potential of the power of lack. The impossibility of diversity is what, at once, conditions the possibility of diversity. We therefore suggest that the symptomatic anxiety provoked by the lack should be enjoyed in order to engage...

  15. Striatum on the anxiety map: Small detours into adolescence.

    2017-01-01

    Adolescence is the most sensitive period for the development of pathological anxiety. Moreover, specific neural changes associated with the striatum might be related to adolescent vulnerability to anxiety. Up to now, the study of anxiety has primarily focused on the amygdala, bed nucleus of the stria terminalis (BNST), hippocampus and ventromedial prefrontal cortex (vmPFC), while the striatum has typically not been considered as part of the anxiety system. This review proposes the addition of the striatum, a complex, multi-component structure, to the anxiety network by underscoring two lines of research. First, the co-occurrence of the adolescent striatal development with the peak vulnerability of adolescents to anxiety disorders might potentially reflect a causal relationship. Second, the recognition of the role of the striatum in fundamental behavioral processes that do affect anxiety supports the putative importance of the striatum in anxiety. These behavioral processes include (1) attention, (2) conditioning/prediction error, and (3) motivation. This review proposes a simplistic schematic representation of the anxiety circuitry that includes the striatum, and aims to promote further work in this direction, as the role of the striatum in shaping an anxiety phenotype during adolescence could have critical implications for understanding and preventing the peak onset of anxiety disorders during this period.

  16. Early Life Experiences and Exercise Associate with Canine Anxieties.

    Directory of Open Access Journals (Sweden)

    Katriina Tiira

    Full Text Available Personality and anxiety disorders across species are affected by genetic and environmental factors. Shyness-boldness personality continuum exists across species, including the domestic dog, with a large within- and across-breed variation. Domestic dogs are also diagnosed for several anxiety-related behavioral conditions, such as generalized anxiety disorders, phobias, and separation anxiety. Genetic and environmental factors contributing to personality and anxiety are largely unknown. We collected questionnaire data from a Finnish family dog population (N = 3264 in order to study the associating environmental factors for canine fearfulness, noise sensitivity, and separation anxiety. Early life experiences and exercise were found to associate with anxiety prevalence. We found that fearful dogs had less socialization experiences (p = 0.002 and lower quality of maternal care (p < 0.0001 during puppyhood. Surprisingly, the largest environmental factor associating with noise sensitivity (p < 0.0001 and separation anxiety (p = 0.007 was the amount of daily exercise; dogs with noise sensitivity and separation anxiety had less daily exercise. Our findings suggest that dogs share many of the same environmental factors that contribute to anxiety in other species as well, such as humans and rodents. Our study highlights the importance of early life experiences, especially the quality of maternal care and daily exercise for the welfare and management of the dogs, and reveals important confounding factors to be considered in the genetic characterization of canine anxiety.

    Full Text Available Background The prevalence of autism spectrum disorders (ASDs has increased 10 times over the past half century, while paternal and maternal age at pregnancy has also increased. Studies looking for an association between paternal or maternal age at pregnancy and ASDs in offspring have not been conclusive. Objective To assess for possible associations between paternal and maternal age at pregnancy and ASDs in offspring. Methods This case-control study had 50 case and 100 control subjects, each case was matched for age and gender to two controls. Case subjects were obtained by consecutive sampling of patients aged 18 months to 7 years who visited the Developmental Behavioral & Community Pediatrics Outpatient Clinic and private growth and development centers from January to April 2013, while control group were children of the same age range and same gender who visited pediatric outpatient clinic at Sanglah Hospital mostly due to acute respiratory tract infection, without ASDs as assessed by the DSM-IV-TR criteria. We interviewed parents to collect the following data: maternal and paternal age at pregnancy, child’s birth weight, history of asphyxia, hospital admission during the neonatal period, pathological labor, maternal smoking during pregnancy, paternal smoking, and gestational age. Data analysis was performed with Chi-square and Fisher’s exact tests. Results Multivariable analysis showed that higher paternal age at pregnancy was associated with ASDs in offspring (OR 6.3; 95%CI 2.0 to 19.3; P 0.001. However, there was no significant association between maternal age during pregnancy and the incidence of ASDs. Asphyxia and paternal smoking were also associated with higher incidence of ASDs in the offspring (OR 10.3; 95%CI 1.9 to 56.5; P 0.007 and OR 3.2; 95%CI 1.5 to 6.9; P 0.003, respectively. Conclusion Paternal age >=40 years increased the risk of ASDs in offspring by 6.3 times. In addition, paternal smoking increased the risk of ASDs in

    Tozzo, Pamela; Caenazzo, Luciana; Parker, Michael J

    2014-03-01

    Misattributed paternity or 'false' paternity is when a man is wrongly thought, by himself and possibly by others, to be the biological father of a child. Nowadays, because of the progression of genetics and genomics the possibility of finding misattributed paternity during familial genetic testing has increased. In contrast to other medical information, which pertains primarily to individuals, information obtained by genetic testing and/or pedigree analysis necessarily has implications for other biologically related members in the family. Disclosing or not a misattributed paternity has a number of different biological and social consequences for the people involved. Such an issue presents important ethical and deontological challenges. The debate centres on whether or not to inform the family and, particularly, whom in the family, about the possibility that misattributed paternity might be discovered incidentally, and whether or not it is the duty of the healthcare professional (HCP) to disclose the results and to whom. In this paper, we consider the different perspectives and reported problems, and analyse their cultural, ethical and legal dimensions. We compare the position of HCPs from an Italian and British point of view, particularly their role in genetic counselling. We discuss whether the Oviedo Convention of the Council of Europe (1997) can be seen as a basis for enriching the debate.

  20. Molecular evidence for high frequency of multiple paternity in a freshwater shrimp species Caridina ensifera.

    Full Text Available Molecular genetic analyses of parentage provide insights into mating systems. Although there are 22,000 members in Malacostraca, not much has been known about mating systems in Malacostraca. The freshwater shrimp Caridina ensifera blue, is a new species belonging to Malacostraca which was discovered recently in Sulawesi, Indonesia. Due to its small body size and low fecundity, this species is an ideal species to study the occurrence and frequency of multiple paternity and to understand of how the low fecundity species persist and evolve.In this study, we developed four polymorphic microsatellites from C. ensifera and applied them to investigate the occurrence and frequency of multiple paternity in 20 C. ensifera broods caught from Lake Matano, Sulawesi. By genotyping the mother and all offspring from each brood we discovered multiple paternity in all 20 broods. In most of the 20 broods, fathers contributed skewed numbers of offspring and there was an apparent inverse correlation between reproductive success of sires and their relatedness to mothers.Our results in combination with recent reports on multiple paternity in crayfish, crab and lobster species suggests that multiple paternity is common in Malacostraca. Skewed contribution of fathers to the numbers of offspring and inverse correlation between reproductive success of sires and their relatedness to mothers suggest that sperm competition occurred and/or pre- and postcopulatory female choice happen, which may be important for avoiding the occurrence of inbreeding and optimize genetic variation in offspring and for persistence and evolution of low fecundity species.

    Paternal behavior and testosterone plasma levels in the Volcano Mouse Neotomodon alstoni (Rodentia: Muridae). Although initially it was thought that testosterone inhibited the display of paternal behavior in males of rodents, it has been shown that in some species high testosterone levels are needed for exhibition of paternal care. In captivity, males of Volcano Mouse (Neotomodon alstoni) provide pups the same care provided by the mother, with the exception of suckling. Here we measured plasmatic testosterone concentrations 10 days after mating, five and 20 days postpartum, and 10 days after males were isolated from their families in order to determine possible changes in this hormone, associated to the presence and age of pups. Males of Volcano Mouse exhibited paternal behavior when their testosterone levels were relatively high. Although levels of this hormone did not change with the presence or pups age, males that invested more time in huddling showed higher testosterone levels. It is possible that in the Volcano Mouse testosterone modulates paternal behavior indirectly, as in the California mouse.

  2. THE EVOLUTION OF PLUMAGE BRIGHTNESS IN BIRDS IS RELATED TO EXTRAPAIR PATERNITY.

    1994-08-01

    A positive association between plumage brightness of male birds and the degree of polygyny may be the result of sexual selection. Although most birds have a socially monogamous mating system, recent paternity analyses show that many offspring are fathered by nonmates. Extrapair paternity arises from extrapair copulations which are frequently initiated by females. Not all females will be able to mate with a male of the preferred phenotype, because of the mating decisions of earlier paired females; extrapair copulations may be a means for females to adjust their precopulation mate choice. We use two comparative analyses (standardized linear contrasts and pairwise comparisons between closely related taxa) to test the idea that male plumage brightness is related to extrapair paternity. Brightness of male plumage and sexual dimorphism in brightness were positively associated with high levels of extrapair paternity, even when potentially confounding variables were controlled statistically. This association between male brightness and extrapair paternity was considerably stronger than the association between male brightness and the degree of polygyny. Cuckoldry thus forms an important component of sexual selection in birds. © 1994 The Society for the Study of Evolution.

    Male mate choice might be based on both absolute and relative strategies. Cues of female attractiveness are thus likely to reflect both fitness and reproductive potential, as well as compatibility with particular male phenotypes. In humans, absolute clues of fertility and indices of favorable developmental stability are generally associated with increased women's attractiveness. However, why men exhibit variable preferences remains less studied. Male mate choice might be influenced by uncertainty of paternity, a selective factor in species where the survival of the offspring depends on postnatal paternal care. For instance, in humans, a man might prefer a woman with recessive traits, thereby increasing the probability that his paternal traits will be visible in the child and ensuring paternity. Alternatively, attractiveness is hypothesized to be driven by self-resembling features (homogamy), which would reduce outbreeding depression. These hypotheses have been simultaneously evaluated for various facial traits using both real and artificial facial stimuli. The predicted preferences were then compared to realized mate choices using facial pictures from couples with at least 1 child. No evidence was found to support the paternity uncertainty hypothesis, as recessive features were not preferred by male raters. Conversely, preferences for self-resembling mates were found for several facial traits (hair and eye color, chin dimple, and thickness of lips and eyebrows). Moreover, realized homogamy for facial traits was also found in a sample of long-term mates. The advantages of homogamy in evolutionary terms are discussed.

    While several studies have investigated maternal exposures as risk factors for oral clefts, few have examined paternal factors. We conducted an international multi-centered case-control study to better understand paternal risk exposures for oral clefts (cases = 392 and controls = 234). Participants were recruited from local hospitals and oral cleft repair surgical missions in Vietnam, the Philippines, Honduras, and Morocco. Questionnaires were administered to fathers and mothers separately to elicit risk factor and family history data. Associations between paternal exposures and risk of clefts were assessed using logistic regression adjusting for potential confounders. A father's personal/family history of clefts was associated with significantly increased risk (adjusted OR: 4.77; 95% CI: 2.41-9.45). No other significant associations were identified for other suspected risk factors, including education (none/primary school v. university adjusted OR: 1.29; 95% CI: 0.74-2.24), advanced paternal age (5-year adjusted OR: 0.98; 95% CI: 0.84-1.16), or pre-pregnancy tobacco use (adjusted OR: 0.96; 95% CI: 0.67-1.37). Although sample size was limited, significantly decreased risks were observed for fathers with selected occupations. Further research is needed to investigate paternal environmental exposures as cleft risk factors.

  7. Paternal investment and status-related child outcomes: timing of father's death affects offspring success.

    2012-09-01

    Recent work in human behavioural ecology has suggested that analyses focusing on early childhood may underestimate the importance of paternal investment to child outcomes since such investment may not become crucial until adolescence or beyond. This may be especially important in societies with a heritable component to status, as later investment by fathers may be more strongly related to a child's adult status than early forms of parental investment that affect child survival and child health. In such circumstances, the death or absence of a father may have profoundly negative effects on the adult outcomes of his children that cannot be easily compensated for by the investment of mothers or other relatives. This proposition is tested using a multigenerational dataset from Bangalore, India, containing information on paternal mortality as well as several child outcomes dependent on parental investment during adolescence and young adulthood. The paper examines the effects of paternal death, and the timing of paternal death, on a child's education, adult income, age at marriage and the amount spent on his or her marriage, along with similar characteristics of spouses. Results indicate that a father's death has a negative impact on child outcomes, and that, in contrast to some findings in the literature on father absence, the effects of paternal death are strongest for children who lose their father in late childhood or adolescence.

    Full Text Available Abstract Background Kin selection is a driving force in the evolution of mammalian social complexity. Recognition of paternal kin using vocalizations occurs in taxa with cohesive, complex social groups. This is the first investigation of paternal kin recognition via vocalizations in a small-brained, solitary foraging mammal, the grey mouse lemur (Microcebus murinus, a frequent model for ancestral primates. We analyzed the high frequency/ultrasonic male advertisement (courtship call and alarm call. Results Multi-parametric analyses of the calls’ acoustic parameters and discriminant function analyses showed that advertisement calls, but not alarm calls, contain patrilineal signatures. Playback experiments controlling for familiarity showed that females paid more attention to advertisement calls from unrelated males than from their fathers. Reactions to alarm calls from unrelated males and fathers did not differ. Conclusions 1 Findings provide the first evidence of paternal kin recognition via vocalizations in a small-brained, solitarily foraging mammal. 2 High predation, small body size, and dispersed social systems may select for acoustic paternal kin recognition in the high frequency/ultrasonic ranges, thus limiting risks of inbreeding and eavesdropping by predators or conspecific competitors. 3 Paternal kin recognition via vocalizations in mammals is not dependent upon a large brain and high social complexity, but may already have been an integral part of the dispersed social networks from which more complex, kin-based sociality emerged.

    To determine the number and type of US workers taking maternity or paternity leave. We created a publicly available ecological long-term series for measuring parental leave from 1994 to 2015 by using the Current Population Survey, which interviews about 60 000 randomly selected households monthly. The average month from 1994 to 2015 saw 273 000 women and 13 000 men on maternity or paternity leave. Maternity leave rates per 10 000 births showed no trend over 22 years (mean = 677.6). Paternity figures increased by a factor of 3, but started from a small base (14.7-54.6). We observed no national impact on maternity or paternity leave after implementation of state laws that provided paid leave. About half (51.1%) of employees on maternity or paternity leave during 2015 received paid time off. The typical woman on maternity leave was older, more likely married, more likely non-Hispanic White, and more educated than the typical woman who gave birth. Although the US economy has expanded dramatically since 1994, this improvement does not appear to have translated into more women taking maternity leave.

    Bisphenol A (BPA) is an endocrine disruptor used in manufacturing of plastic devices, resulting in an ubiquitous presence in the environment linked to human infertility, obesity or cardiovascular diseases. Both transcriptome and epigenome modifications lie behind these disorders that might be inherited transgenerationally when affecting germline. To assess potential effects of paternal exposure on offspring development, adult zebrafish males were exposed to BPA during spermatogenesis and mated with non-treated females. Results showed an increase in the rate of heart failures of progeny up to the F2, as well as downregulation of 5 genes involved in cardiac development in F1 embryos. Moreover, BPA causes a decrease in F0 and F1 sperm remnant mRNAs related to early development. Results reveal a paternal inheritance of changes in the insulin signaling pathway due to downregulation of insulin receptor β mRNAs, suggesting a link between BPA male exposure and disruption of cardiogenesis in forthcoming generations. - Highlights: • We examine the effects of adult male exposure to BPA on the progeny (F1 and F2). • Paternal exposure promotes similar cardiac malformations to those caused by direct exposure. • BPA applied during spermatogenesis decrease the insra and insrb transcripts in spermatozoa. • Sperm insrb transcript controls embryonic expression being the downregulation inherited by F1. • Paternal BPA exposure impairs heart development in F1 and F2 disrupting insulin signaling pathway. - Paternal bisphenol A exposure impairs cardiac development throughout generations.

  11. The evolution and suppression of male suicide under paternal genome elimination.

    Different genetic systems can be both the cause and the consequence of genetic conflict over the transmission of genes, obscuring their evolutionary origin. For instance, with paternal genome elimination (PGE), found in some insects and mites, both sexes develop from fertilized eggs, but in males the paternally derived chromosomes are either lost (embryonic PGE) or deactivated (germline PGE) during embryogenesis and not transmitted to the next generation. Evolution of germline PGE requires two transitions: (1) elimination of the paternal genome during spermatogenesis; (2) deactivation of the paternal genome early in development. Hypotheses for the evolution of PGE have mainly focused on the first transition. However, maternal genes seem to be responsible for the deactivation and here we investigate if maternal suppression could have evolved in response to paternally expressed male suicide genes. We show that sibling competition can cause such genes to spread quickly and that inbreeding is necessary to prevent fixation of male suicide, and subsequent population extinction. Once male-suicide has evolved, maternally expressed suppressor genes can invade in the population. Our results highlight the rich opportunity for genetic conflict in asymmetric genetic systems and the counterintuitive phenotypes that can evolve as a result. © 2010 The Author(s).

    Body size, social setting, and the physical environment can all influence reproductive behaviours, but their interactions are not well understood. Here, we investigated how male body size, male-male competition, and water turbidity influence nest-building behaviour in the sand goby (Pomatoschistus minutus), a marine fish with exclusive paternal care. We found that environmental and social factors affected the nest characteristics of small and large males differently. In particular, association between male size and the level of nest elaboration (i.e. the amount of sand piled on top of the nest) was positive only under clear water conditions. Similarly, male size and nest entrance size were positively associated only in the absence of competition. Such interactions may, in turn, help to explain the persistence of variation in reproductive behaviours, which-due to their importance in offspring survival-are otherwise expected to be under strong balancing selection.

    2015-09-01

    The DSM-5 process, and the publication of DSM-5 in 2013, have had a considerable impact on the classification of anxiety disorders. Major changes included the reorganization of the chapter structure, individual groupings of disorders within each chapter from a life span viewpoint, and the use of specifiers. The DSM-5 chapter on anxiety disorders does not include obsessive-compulsive disorder or post-traumatic stress disorder. The chapter itself now reflects a developmental approach. The text of each disorder has been enhanced with short sections on development and course, risk and prognostic factors, etc. It is expected that the reformulation of anxiety disorders in DSM-5 will lead to greater precision in a variety of ways, as illustrated in the papers in this issue of Dialogues in Clinical Neuroscience. In summary, these changes in the way we classify anxiety disorders reflect our best view on the clinical empirical data and should prove useful in the assessment of specific anxiety disorders.

    Full Text Available Tobacco use is the first preventable cause of death. This is associated not only with physical illness and a shorter life expectancy, but also with different mental disorders such as anxiety disorders. Given the low risk perception of use, this paper reports a systematic review of the scientific literature on the relationship between anxiety and tobacco from an emotional perspective, including data on smoking prevalence, factors associated with the onset and maintenance of tobacco use, as well as those factors that hamper smoking cessation and increase relapse rates. The high rates of comorbidity between tobacco use and anxiety disorders make necessary the development of new and better tobacco cessation treatments, especially designed for those smokers with high state anxiety or anxiety sensitivity, with the aim of maximizing the efficacy.

    Depression and anxiety are the most common mental health conditions during pregnancy and can impair the normal development of mother-infant interactions. These adversities are associated with low birth weight and increased risk of behavioural disorders in children. We recently reported reduced expression of the imprinted gene PATERNALLY EXPRESSED GENE 3 (PEG3) in placenta of human infants born to depressed mothers. Expression of Peg3 in the brain has previously been linked maternal behaviour in rodents, at least in some studies, with mutant dams neglecting their pups. However, in our human study decreased expression was in the placenta derived from the fetus. Here, we examined maternal behaviour in response to reduced expression of Peg3 in the feto-placental unit. Prenatally we found novelty reactivity was altered in wild-type females carrying litters with a null mutation in Peg3. This behavioural alteration was short-lived and there were no significant differences the transcriptomes of either the maternal hypothalamus or hippocampus at E16.5. In contrast, while maternal gross maternal care was intact postnatally, the exposed dams were significantly slower to retrieve their pups and displayed a marked increase in anxiety. We also observed a significant reduction in the isolation-induced ultrasonic vocalizations (USVs) emitted by mutant pups separated from their mothers. USVs are a form of communication known to elicit maternal care suggesting Peg3 mutant pups drive the deficit in maternal behaviour. These data support the hypothesis that reduced placental PEG3 in human pregnancies occurs as a consequence of prenatal depression but leaves scope for feto-placental Peg3 dosage, during gestation, influencing aspects of maternal behaviour. © The Author(s) 2017.

    Despite the often social nature of smoking, relatively little research has been conducted on the relationship between smoking and social anxiety disorder (SAD). Participants (N=99) included 34 smokers without current mental health disorders, 37 smokers with SAD, and 28 smokers who met criteria for other anxiety disorder diagnoses (e.g., panic disorder or generalized anxiety disorder, but not SAD). Nicotine and placebo patches were administered to participants in a counterbalanced manner across two assessment days. Urge and craving were assessed before and after a 5-h nicotine absorption/deprivation period. Compared to smokers without current mental health disorders, smokers with SAD did not report greater nicotine dependence, but did endorse greater motivation to use nicotine to avoid negative outcomes. In addition, after controlling for demographic variables, smoking characteristics, pre-deprivation urge and craving, and other anxiety/depression symptoms, social anxiety symptoms uniquely predicted urge and craving in the placebo patch condition; however, social anxiety had no influence on urge and craving in the nicotine patch condition. These findings suggest that one potential reason that smokers with SAD may have worse cessation outcomes is that they may experience higher levels of craving and urge to smoke during quit attempts. Thus, during a quit attempt, particularly in the absence of nicotine replacement therapy, smokers with SAD are likely to benefit from additional treatment aimed at managing or reducing their social anxiety symptoms.

    Symptoms of anxiety and depression are significantly associated in parents and children, but few studies have examined associations between recurrent parental problems and offspring symptoms, and fathers have rarely been included in these studies. Additionally, few have investigated factors that may protect against familial aggregation of anxiety and depression. The aims of the present study are to examine the associations between recurrent parental anxiety/depression over a ten-year time span and offspring anxiety/depression in adolescence and to test whether two factors proposed to be inversely related to anxiety and depression, namely, adolescent self-esteem and physical activity, may moderate and mediate the transmission of anxiety/depression. This study used data from two waves of a Norwegian community study (the HUNT study) consisting of 5,732 adolescents, ages 13-18, (mean age = 15.8, 50.3% girls) who had one (N = 1,761 mothers; N = 742 fathers) or both parents (N = 3,229) participating in the second wave. In the first wave, 78% of the parents also participated. The adolescents completed self-reported questionnaires on self-esteem, physical activity, and symptoms of anxiety/depression, whereas parents reported on their own anxiety/depressive symptoms. The data were analysed with structural equation modeling. The presence of parental anxiety/depression when offspring were of a preschool age predicted offspring anxiety/depression when they reached adolescence, but these associations were entirely mediated by current parental symptoms. Self-esteem partly mediated the associations between anxiety/depression in parents and offspring. No sex differences were found. Physical activity moderated the direct associations between anxiety/depression in mothers and offspring, whereas no moderating effect was evident with regard to paternal anxiety/depression. These findings suggest that children of parents with anxiety/depression problems are at a sustained risk for

    Full Text Available De novo mutations (DNM are an important source of rare variants and are increasingly being linked to the development of many diseases. Recently, the paternal age effect has been the focus of a number of studies that attempt to explain the observation that increasing paternal age increases the risk for a number of diseases. Using disease-free familial quartets we show that there is a strong positive correlation between paternal age and germline DNM in healthy subjects. We also observed that germline CNVs do not follow the same trend, suggesting a different mechanism. Finally, we observed that DNM were not evenly distributed across the genome, which adds support to the existence of DNM hotspots.

    Full Text Available This study aimed to assess current and retrospective levels of reported and desired paternal involvement experienced by young adult daughters, as well as current and retrospective levels of paternal nurturance. A sample of 89, female, third year South African Psychology students completed self-administered questionnaires, consisting of a biographical questionnaire, four Father Involvement Scales and two Nurturant Father Scales. Daughters reported their fathers as having been involved and nurturing while growing up. Although they indicated that they perceived fathers as somewhat less involved in young adulthood; they reported being satisfied with the level of father involvement. Daughters also reported high current paternal nurturance. The findings therefore indicate that a group of middle to upper middle-class South African daughters perceived their fathers as relatively involved in their lives and suggest that their fathers’ involvement extends beyond traditional father roles.

    Systematic reviews have established that partner support protects against perinatal mood problems. It is therefore a key target for interventions designed to prevent maternal and paternal depression and anxiety. Nonetheless, the extant literature is yet to be translated into specific actions that parents can implement. Prevention efforts aiming to facilitate reciprocal partner support within the couple dyad need to provide specific guidance on how partners can support one another to reduce their vulnerability to perinatal depression and anxiety. Two panels of experts in perinatal mental health (21 consumer advocates and 39 professionals) participated in a Delphi consensus study to establish how partners can support one another to reduce their risk of developing depression and anxiety during pregnancy and the postpartum period. A total of 214 recommendations on how partners can support each other were endorsed by at least 80 % of both panels as important or essential in reducing the risk of perinatal depression and anxiety. The recommendations were grouped under the following categories: becoming a parent, supporting each other through pregnancy and childbirth, communication, conflict, division of labor, practical support, emotional support, emotional closeness, sexual satisfaction, using alcohol and drugs, encouraging self-care, developing acceptance, and help-seeking. This study established consensus between consumers and professionals in order to produce a set of guidelines on how partners can support each other to prevent depression and anxiety during pregnancy and following childbirth. It is hoped that these guidelines will inform the development of perinatal depression and anxiety prevention efforts.

  7. Fear inhibition in high trait anxiety.

    Directory of Open Access Journals (Sweden)

    Merel Kindt

    Full Text Available Trait anxiety is recognized as an individual risk factor for the development of anxiety disorders but the neurobiological mechanisms remain unknown. Here we test whether trait anxiety is associated with impaired fear inhibition utilizing the AX+/BX- conditional discrimination procedure that allows for the independent evaluation of startle fear potentiation and inhibition of fear. Sixty undergraduate students participated in the study--High Trait Anxious: n = 28 and Low Trait Anxious: n = 32. We replicated earlier findings that a transfer of conditioned inhibition for startle responses requires contingency awareness. However, contrary to the fear inhibition hypothesis, our data suggest that high trait anxious individuals show a normal fear inhibition of conditioned startle responding. Only at the cognitive level the high trait anxious individuals showed evidence for impaired inhibitory learning of the threat cue. Together with other findings where impaired fear inhibition was only observed in those PTSD patients who were either high on hyperarousal symptoms or with current anxiety symptoms, we question whether impaired fear inhibition is a biomarker for the development of anxiety disorders.

    Generalized anxiety disorder (GAD) has a lifetime prevalence in the US population of about 5.7%. Typically, GAD begins in early adulthood and tends to have a chronic and persistent course. The disorder frequently presents comorbidly with other conditions, and about 90% of patients with GAD have at least 1 comorbid lifetime psychiatric disorder. Patients with GAD tend to be high users of medical services; the disorder is associated with significant physical as well as psychological symptomatology and impacts health, family relationships, and employment. Pharmacologic and psychosocial treatments are available for GAD. Different side effect profiles, speed of onset of action, and discontinuation requirements of individual drugs need to be taken into account when selecting treatment. Treatment selection should include consideration of comorbidity, psychological function, social impairment, and refractoriness, as well as the need for ongoing intervention for many individuals. Innovative treatments, including anticonvulsants, atypical antipsychotics, and others, as well as treatment targeting concomitant insomnia, may help improve outcomes for affected individuals.

    Paternity testing in Italy is usually performed by private laboratories and universities having direct contacts with the applicants. Recently, the number of paternity tests offered through laboratory websites has increased in Italy and Europe. The execution of genetic tests, including paternity testing based on DNA analysis, represents a complex act, which contains three main steps. Paternity analyses carried out by laboratories via Internet are performed on samples collected by the applicants and then mailed back to the laboratories without any patient-physician relationship. Information is given to the subjects through the laboratory's website or mailed with the test order form. The execution of "household" DNA analysis without technical precautions may provide an incorrect response with severe consequences on the individual who has undergone testing, on the family involved, and on society in general. The problems connected with this kind of analysis are not technical, but ethical and deontological. In this work, we will discuss the problems related to information and consent by way of outlining the relevant Italian laws and codes of medical ethics. The Italian Privacy's Guarantor is assessing the ethical and legal implications, but regulations are not yet in place. We believe that adequate information related to this practice cannot be given via Internet, and, consequently, the validity of the consent expressed during this kind of procedure can be uncertain. Further, we will analyze issues regarding the importance of minors' protection when a paternity test is performed via Internet. In our opinion, the complexity of the situations and expectations linked to paternity investigations require a special sensitivity in dealing with each case, based on a patient-physician relationship in the decision-making process especially referring to the defense of the minors' well-being.

Most theories about the benefits of polyandry come from studies of terrestrial animals, which have relatively complex mating systems and behaviors; less is known about the potential benefits of polyandry in sessile marine animals, for which potential mates may be scarce and females have less control over pre-copulatory mate choice. Here, we used microsatellite markers to examine multiple paternity in natural aggregations of the Pacific gooseneck barnacle Pollicipes elegans, testing the effect of density on paternity and mate relatedness on male reproductive success. We found that multiple paternity was very common (79% of broods), with up to five fathers contributing to a brood, though power was relatively low to detect more than four fathers. Density had a significant and positive linear effect on the number of fathers siring a brood, though this relationship leveled off at high numbers of fathers, which may reflect a lack of power and/or an upper limit to polyandry in this species. Significant skew in male reproductive contribution in multiply-sired broods was observed and we found a positive and significant relationship between the proportion of offspring sired and the genetic similarity between mates, suggesting that genetic compatibility may influence reproductive success in this species. To our knowledge, this is the first study to show high levels of multiple paternity in a barnacle, and overall, patterns of paternity in P. elegans appear to be driven primarily by mate availability. Evidence of paternity bias for males with higher relatedness suggests some form of post-copulatory sexual selection is taking place, but more work is needed to determine whether it operates during or post-fertilization. Overall, our results suggest that while polyandry in P. elegans is driven by mate availability, it may also provide a mechanism

    Controversy surrounds the diagnostic categorization of generalized anxiety disorder (GAD). To examine the incidence, comorbidity, and risk patterns for anxiety and depressive disorders and to test whether developmental features of GAD more strongly support a view of this condition as a depressive as opposed to an anxiety disorder. Face-to-face, 10-year prospective longitudinal and family study with as many as 4 assessment waves. The DSM-IV Munich Composite International Diagnostic Interview was administered by clinically trained interviewers. Munich, Germany. A community sample of 3021 individuals aged 14 to 24 years at baseline and 21 to 34 years at last follow-up. Cumulative incidence of GAD, other anxiety disorders (specific phobias, social phobia, agoraphobia, and panic disorder), and depressive disorders (major depressive disorder, and dysthymia). Longitudinal associations between GAD and depressive disorders are not stronger than those between GAD and anxiety disorders or between other anxiety and depressive disorders. Survival analyses reveal that the factors associated with GAD overlap more strongly with those specific to anxiety disorders than those specific to depressive disorders. In addition, GAD differs from anxiety and depressive disorders with regard to family climate and personality profiles. Anxiety and depressive disorders appear to differ with regard to risk constellations and temporal longitudinal patterns, and GAD is a heterogeneous disorder that is, overall, more closely related to other anxiety disorders than to depressive disorders. More work is needed to elucidate the potentially unique aspects of pathways and mechanisms involved in the etiopathogenesis of GAD. Grouping GAD with depressive disorders, as suggested by cross-sectional features and diagnostic comorbidity patterns, minimizes the importance of longitudinal data on risk factors and symptom trajectories.

    Full Text Available Although the majority of passerine birds are socially monogamous, true genetic monogamy is rare, with extra-pair paternity (EPP occurring in almost 90% of surveyed socially monogamous species. We present the first molecular data on the genetic breeding system of the long-tailed finch, Poephila acuticauda, a grass finch endemic to the tropical northern savannah of Australia. Although the species forms socially monogamous pair bonds during the breeding season, we found that extra-pair males sired 12.8% of 391 offspring, in 25.7% of 101 broods. Our findings provide only the second estimate of extra-pair paternity in the estrildid finch family.

  17. Toward a New Model of Fatherhood? Discourses on the Process of Paternal Involvement in Urban Spain

    Directory of Open Access Journals (Sweden)

    Marc Barbeta-Viñas

    2017-01-01

    Full Text Available In recent decades quantitative studies have documented an increase in paternal involvement. These changes have led to hypotheses of a new model of fatherhood. The aim of this paper is to explore the discourses of Spanish fathers regarding paternal involvement, identifying its structure and changing tendencies. The analysis is based on eight focus groups conducted in Madrid and Barcelona. Among the main findings we emphasize that the transition of fatherhood,not without contradictions, is causing the traditional homogeneous fatherhood to evolve toward a more complex and multidimensional conceptualization.

    This study extends the current use of Bayesian networks by incorporating the effects of allelic dependencies in paternity calculations. The use of object-oriented networks greatly simplify the process of building and interpreting forensic identification models, allowing researchers to solve new, more complex problems. We explore two paternity examples: the most common scenario where DNA evidence is available from the alleged father, the mother and the child; a more complex casewhere DNA is not available from the alleged father, but is available from the alleged father's brother. Object-oriented networks are built, using HUGIN, for each example which incorporate the effects of allelic dependence caused by evolutionary relatedness.

    2013-01-01

    Anxiety disorders are the most prevalent mental health conditions. Although they are less visible than schizophrenia, depression, and bipolar disorder, they can be just as disabling. The diagnoses of anxiety disorders are being continuously revised. Both dimensional and structural diagnoses have been used in clinical treatment and research, and both methods have been proposed for the new classification in the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-5). However, each of these approaches has limitations. More recently, the emphasis in diagnosis has focused on neuroimaging and genetic research. This approach is based partly on the need for a more comprehensive understanding of how biology, stress, and genetics interact to shape the symptoms of anxiety. Anxiety disorders can be effectively treated with psychopharmacological and cognitive–behavioral interventions. These inter ventions have different symptom targets; thus, logical combinations of these strategies need to be further studied in order to improve future outcomes. New developments are forthcoming in the field of alternative strategies for managing anxiety and for treatment-resistant cases. Additional treatment enhancements should include the development of algorithms that can be easily used in primary care and with greater focus on managing functional impairment in patients with anxiety.

    2017-05-24

    To measure the occurrence and levels of depression, anxiety and stress in undergraduate dental students using the Depression, Anxiety and Stress Scale (DASS-21). This cross-sectional study was conducted in November and December of 2014. A total of 289 dental students were invited to participate, and 277 responded, resulting in a response rate of 96%. The final sample included 247 participants. Eligible participants were surveyed via a self-reported questionnaire that included the validated DASS-21 scale as the assessment tool and questions about demographic characteristics and methods for managing stress. Abnormal levels of depression, anxiety and stress were identified in 55.9%, 66.8% and 54.7% of the study participants, respectively. A multiple linear regression analysis revealed multiple predictors: gender (for anxiety b=-3.589, p=.016 and stress b=-4.099, p=.008), satisfaction with faculty relationships (for depression b=-2.318, p=.007; anxiety b=-2.213, p=.004; and stress b=-2.854, pstress b=-2.854, pstress b=-2.648, p=.045). The standardized coefficients demonstrated the relationship and strength of the predictors for each subscale. To cope with stress, students engaged in various activities such as reading, watching television and seeking emotional support from others. The high occurrence of depression, anxiety and stress among dental students highlights the importance of providing support programs and implementing preventive measures to help students, particularly those who are most susceptible to higher levels of these psychological conditions.

    In palliative care, the intensity and duration of anxiety as well as its consequences on the patient's daily activities can significantly decrease his quality of life. Anxiety that does not incapacitate the patient to the point of his being unable to communicate or perform his usual activities does not necessarily require drug treatment. The non pharmacological treatments of anxiety are presented in some detail. Prescription of anxiolytic drugs in renal or hepatic failure, as well as when oral intake or venous access are difficult, is briefly discussed.

    In socially monogamous species, individuals can use extra-pair paternity and offspring sex allocation as adaptive strategies to ameliorate costs of genetic incompatibility with their partner. Previous studies on domesticated Gouldian finches (Erythrura gouldiae) demonstrated a genetic incompatibility between head colour morphs, the effects of which are more severe in female offspring. Domesticated females use differential sex allocation, and extra-pair paternity with males of compatible head colour, to reduce fitness costs associated with incompatibility in mixed-morph pairings. However, laboratory studies are an oversimplification of the complex ecological factors experienced in the wild and may only reflect the biology of a domesticated species. This study aimed to examine the patterns of parentage and sex ratio bias with respect to colour pairing combinations in a wild population of the Gouldian finch. We utilized a novel PCR assay that allowed us to genotype the morph of offspring before the morph phenotype develops and to explore bias in morph paternity and selection at the nest. Contrary to previous findings in the laboratory, we found no effect of pairing combinations on patterns of extra-pair paternity, offspring sex ratio or selection on morphs in nestlings. In the wild, the effect of morph incompatibility is likely much smaller, or absent, than was observed in the domesticated birds. Furthermore, the previously studied domesticated population is genetically differentiated from the wild population, consistent with the effects of domestication. It is possible that the domestication process fostered the emergence (or enhancement) of incompatibility between colour morphs previously demonstrated in the laboratory. © 2016 European Society For Evolutionary Biology.

    Previous research has found that maternal stress during pregnancy increases the risk of offspring asthma. However, whether this association is consistent with a causal interpretation has never been tested. The objective is to determine whether there is a critical exposure period for maternal depression or anxiety on offspring asthma or whether cumulative exposure is most important, and to investigate evidence of confounding. The study population included all children born in Sweden from July 2006 to December 2009 (n = 360 526). Information about childhood asthma, maternal depression or anxiety (diagnosis or medication) and covariates was obtained from the Swedish national health registers. The associations between exposure periods (pre-conception, pregnancy, postnatal or current) and childhood asthma were estimated using structured life course approach hypothesis testing. Paternal and cousin analyses were used to test for evidence of confounding from shared genes and environment. For childhood asthma, cumulative exposure best described the effect of exposure to maternal depression or anxiety up to a maximum of any two exposure periods [adjusted odds ratio 1.44, 95% confidence interval (CI) 1.38, 1.52]. The hypotheses of a critical period were not supported. The paternal and cousin analyses indicated minimal influence from familial confounding. These findings support an association between cumulative exposure to maternal depression or anxiety and asthma development in offspring. This association is unique for maternal depression or anxiety and not due to familial confounding. The clinical implication is that effective psychological management of women with chronic distress may reduce offspring asthma risk. © The Author 2017; all rights reserved.

    Maternal depression and anxiety during pregnancy have been associated with offspring-attention deficit problems. We explored possible intrauterine effects by comparing maternal and paternal symptoms during pregnancy, by investigating cross-cohort consistency, and by investigating whether parental symptoms in early childhood may explain any observed intrauterine effect. This study was conducted in two cohorts (Generation R, n = 2,280 and ALSPAC, n = 3,442). Pregnant women and their partners completed questionnaires to assess symptoms of depression and anxiety. Child attention problems were measured in Generation R at age 3 with the Child Behavior Checklist, and in ALSPAC at age 4 with the Strengths and Difficulties Questionnaire. In both cohorts, antenatal maternal symptoms of depression (Generation R: OR 1.23, 95% CI 1.05-1.43; ALSPAC: OR 1.33, 95% CI 1.19-1.48) and anxiety (Generation R: OR 1.24, 95% CI 1.06-1.46; ALSPAC: OR 1.32, 95% CI 1.19-1.47) were associated with a higher risk of child attention problems. In ALSPAC, paternal depression was also associated with a higher risk of child attention problems (OR 1.11, 95% CI 1.00-1.24). After adjusting for maternal symptoms after giving birth, antenatal maternal depression and anxiety were no longer associated with child attention problems in Generation R. Moreover, there was little statistical evidence that antenatal maternal and paternal depression and anxiety had a substantially different effect on attention problems of the child. The apparent intrauterine effect of maternal depression and anxiety on offspring-behavioural problems may be partly explained by residual confounding. There was little evidence of a difference between the strength of associations of maternal and paternal symptoms during pregnancy with offspring-attention problems. That maternal symptoms after childbirth were also associated with offspring-behavioural problems may indicate a contribution of genetic influences to the association. © 2012

    Personality and anxiety disorders across species are affected by genetic and environmental factors. Shyness-boldness personality continuum exists across species, including the domestic dog, with a large within- and across-breed variation. Domestic dogs are also diagnosed for several anxiety-related behavioral conditions, such as generalized anxiety disorders, phobias, and separation anxiety. Genetic and environmental factors contributing to personality and anxiety are largely unknown. We collected questionnaire data from a Finnish family dog population (N = 3264) in order to study the associating environmental factors for canine fearfulness, noise sensitivity, and separation anxiety. Early life experiences and exercise were found to associate with anxiety prevalence. We found that fearful dogs had less socialization experiences (p = 0.002) and lower quality of maternal care (p dogs with noise sensitivity and separation anxiety had less daily exercise. Our findings suggest that dogs share many of the same environmental factors that contribute to anxiety in other species as well, such as humans and rodents. Our study highlights the importance of early life experiences, especially the quality of maternal care and daily exercise for the welfare and management of the dogs, and reveals important confounding factors to be considered in the genetic characterization of canine anxiety.

    Homomorphic self-incompatibility is a well-studied example of a physiological process that is thought to increase population diversity and reduce the expression of inbreeding depression. Whereas theoretical models predict the presence of a large number of S-haplotypes with equal frequencies at equilibrium, unequal allele frequencies have been repeatedly reported and attributed to sampling effects, population structure, demographic perturbation, sheltered deleterious mutations or selection pressure on linked genes. However, it is unclear to what extent unequal segregations are the results of gametophytic or sexual selection. Although these two forces are difficult to disentangle, testing S-alleles in the offspring of controlled crosses provides an opportunity to separate these two phenomena. In this work, segregation and transmission of S-alleles have been characterized in progenies of mixed donors and fully compatible pollinations under field conditions in Prunus avium. Seed set patterns and pollen performance have also been characterized. The results reveal paternal-specific distorted transmission of S-alleles in most of the crosses. Interestingly, S-allele segregation within any given paternal or maternal S-locus was random. Observations on pollen germination, pollen tube growth rate, pollen tube cohort size, seed set dynamics and transmission patterns strongly suggest post-pollination, prezygotic sexual selection, with male-male competition as the most likely mechanism. According to these results, post-pollination sexual selection takes precedence over frequency-dependent selection in explaining unequal S-haplotype frequencies. © 2015 European Society For Evolutionary Biology.

    Full Text Available The paper ostensibly refers to Harold Bloom’s categories of the anxiety of influence. Bloom’s theory is treated as an immanentist one, i.e. text/aesthetics/personality-oriented, which is specific to the period in which the theory was developed. However, at least from the 80s of the XXth century, there occurs a visible change towards sociologization of all the human sciences. The paper appropriates and resignificates Bloom’s categories and intermingles them with the concepts of social psychology in order to enable a description of the condition of writers in the current social context

    Centenarians' psychological well-being is presently of great interest in psychogeriatric research but little is known about factors that specifically account for the presence of clinically relevant anxiety symptoms in this age group. This study examined the presence of anxiety and its predictors in a sample of centenarians and aims to contribute to a better understanding of anxiety determinants in extreme old age. We examined how socio-demographic, health, functional, and social factors contribute to the presence of clinically significant anxiety symptoms in centenarians recruited from two Portuguese centenarian studies. The Geriatric Anxiety Inventory - Short Form (GAI-SF) was used to assess anxiety symptoms. A total of 97 centenarians (mean age 101.1 years; SD = 1.5 years; range = 100-108) with no/minor cognitive impairment were included. Clinically significant anxiety symptoms (GAI-SF ≥3) were present in 45.4% (n = 44) of the sample. Main predictive factors included worse health perception, higher number of medical conditions, financial concerns related to medical expenses (income inadequacy) and loneliness. Results suggest that along with health status (subjective and objective), income inadequacy related to medical expenses and feeling lonely may predispose centenarians to clinically significant anxiety and be important to their overall well-being. Further research is needed on the repercussions of clinical anxiety in centenarians' quality of life and on co-morbid conditions (e.g. depression) at such advanced ages.

    correlated to male fertility, could be considered as potential traits to select for in order to genetically improving this trait. However, only the semen pH has been checked for this purpose, and a negative result has been obtained. Other traits can be studied in the future but bearing in mind that the required experiments will need large number of bucks for an accurate estimation of the genetic correlation of the trait with male fertility. This means that these experiments will be expensive and difficult to set up. The most common criterion to select paternal lines, average daily gain, seems not to be genetically correlated to male fertility and seminal traits. Thus, selection for average daily gain has no detrimental consequences on these traits, and a multi-trait selection, including growth rate and seminal traits directly related to an efficient AI semen dose production, is feasible in paternal lines. The male contribution to fertility after natural mating and after AI with semen doses with high concentration is negligible, but it has been found that, under more restrictive conditions of AI, male contributions to fertility and litter size are low but higher in magnitude than the ones obtained after natural mating. The genetic correlation between the female and male contributions to fertility has been found to be moderate to high and positive.

    It is widely assumed that the mating system of the humpback whale, Megaptera novaeangliae, is similar to that of most mammals in that it represents some form of polygyny or promiscuity, but this cannot be tested without observations of copulation or data on paternity of offspring.

    The aquatic ecosystems of the Great Lakes are contaminated with a variety of compounds, some of which are considered reproductive toxicants. Few studies of paternal fish consumption and reproductive endpoints have been undertaken and serve as the impetus for study. Standardized telephone interviews were conducted with 2,445 female members of the New York State Angler Cohort (82% response) to update reproductive profiles and to ascertain specific information on time-to-pregnancy (TTP). The study sample includes women with a known TTP and paternal fish consumption data (n = 785). Conception delay was defined as more than 12 cycles of unprotected intercourse to achieve pregnancy. Paternal fish consumption was assessed by three measures: frequency of Lake Ontario sport fish meals in 1991, numbers of years eating fish, and estimated PCB exposure from fish consumption. Adjusted ORs for number of fish meals, based on logistic regression, ranged from 0.69 to 0.80; from 0.61 to .82 for number of years eating fish; and from 0.44 to 1.14 for quartiles of estimated PCB exposure from fish consumption. All confidence intervals included one. These findings suggest that, based on paternal self-reports, Lake Ontario fish consumption does not increase the risk of conception delay.

    Conclusion: Recurrent autosomal dominant OI may occur in the offspring of unaffected parents with parental gonadal mosaicism. Genetic counseling of recurrent autosomal dominant OI should include a thorough mutational analysis of the family members, and mutational analysis of the sperm may detect paternal gonadal mosaicism for the mutation.

    Human birth weight is subject to stabilizing selection; babies born too small or too large are less likely to survive. Particular combinations of maternal/fetal immune system genes are associated with pregnancies where the babies are ≤ 5th birth weight centile, specifically an inhibitory maternal KIR AA genotype with a paternally derived fetal HLA-C2 ligand. We have now analyzed maternal KIR and fetal HLA-C combinations at the opposite end of the birth weight spectrum. Mother/baby pairs (n = 1316) were genotyped for maternal KIR as well as fetal and maternal HLA-C. Presence of a maternal-activating KIR2DS1 gene was associated with increased birth weight in linear or logistic regression analyses of all pregnancies >5th centile (p = 0.005, n = 1316). Effect of KIR2DS1 was most significant in pregnancies where its ligand, HLA-C2, was paternally but not maternally inherited by a fetus (p = 0.005, odds ratio = 2.65). Thus, maternal KIR are more frequently inhibitory with small babies but activating with big babies. At both extremes of birth weight, the KIR associations occur when their HLA-C2 ligand is paternally inherited by a fetus. We conclude that the two polymorphic immune gene systems, KIR and HLA-C, contribute to successful reproduction by maintaining birth weight between two extremes with a clear role for paternal HLA.

    Patterns of inheritance of the chloroplast genome in Passiflora were analyzed by examining the progeny from both interspecific and intraspecific crosses. Artificial crosses of field-collected material were performed in greenhouses at The University of Texas at Austin. DNA from fresh leaf material was analyzed by Southern blot techniques to identify the donor of the chloroplast genome. Initially, single progeny were analyzed for 11 crosses; two intraspecific crosses demonstrated maternal inheritance, whereas the nine interspecific crosses had paternal inheritance. Subsequently, the donor of the chloroplast genome was determined for multiple progeny in seven crosses. Passiflora oerstedii × P. retipetala showed strict paternal inheritance in all of 17 progeny. A series of five crosses and backcrosses between P. oerstedii and P. menispermifolia demonstrated strictly paternal inheritance. Finally, when 15 progeny were analyzed for the P. costaricensis × P. costaricensis cross, 12 of the 15 showed maternal inheritance, whereas the remaining three were biparental. Interestingly, all interspecific crosses had primarily paternal inheritance, whereas all intraspecific crosses had primarily maternal inheritance. The implications of heteroplasmy on phylogenetic analyses of chloroplast DNA are discussed.

  20. High fidelity--no evidence for extra-pair paternity in Siberian jays (Perisoreus infaustus.

    Directory of Open Access Journals (Sweden)

    Phillip Gienapp

    Full Text Available Extra-pair paternity (EPP in birds is related to a number of ecological and social factors. For example, it has been found to be positively related with breeding density, negatively with the amount of paternal care and especially high rates have been observed in group-living species. Siberian jays (Perisoreous infaustus breed at low densities and have extended parental care, which leads to the expectation of low rates of EPP. On the other hand, Siberian jays live in groups which can include also unrelated individuals, and provide opportunities for extra-pair matings. To assess the potential occurrence of EPP in Siberian jays, we analysed a large data pool (n=1029 offspring covering ca. 30 years of samples from a Finnish Siberian jay population. Paternities were assigned based on up to 21 polymorphic microsatellite markers with the additional information from field observations. We were unable to find any evidence for occurrence of EPP in this species. Our findings are in line with earlier studies and confirm the generally low rates of EPP in related Corvid species. These results suggest that ecological factors may be more important than social factors (group living in determining costs and benefits of extra-pair paternity.

    2018-01-01

    Full Text Available In a video that showcases a new Facebook feature, Mark Zuckerberg chats to his users, telling them that he’s “just hanging out with you in my backyard.” In this video-which is on his Facebook page-Zuckerberg discloses the domestic space of his backyard, revealing his interaction with family and friends. Depicted hosting a barbeque while watching the electoral debate, Zuckerberg performs an affective white postfeminist paternity (Hamad, 2014 by talking about hunting, eating meat, and being a father. This video is key in explaining how Zuckerberg affectively models patriarchal power. We argue that this PR exercise (for both him and Facebook which are portrayed as inextricably linked functions to represent Facebook as enabling an empowered “community,” rather than being just an instrument of data accumulation. In particular, Zuckerberg’s affective paternalism is also a means to recoup and obfuscate patriarchal power structures. Zuckerberg’s Facebook page constructs an intimate paternalism in relation to his domestic sphere, but also to his followers, and this works to legitimate his corporate and global paternalism. The ways in which he is portrayed through signifiers of an emotional fatherhood work to gloss his power as the third richest man in the world.

    Full Text Available BACKGROUND: Advanced paternal age (APA is associated with an increased risk of neurodevelopmental disorders such as autism and schizophrenia, as well as with dyslexia and reduced intelligence. The aim of this study was to examine the relationship between paternal age and performance on neurocognitive measures during infancy and childhood. METHODS AND FINDINGS: A sample of singleton children (n = 33,437 was drawn from the US Collaborative Perinatal Project. The outcome measures were assessed at 8 mo, 4 y, and 7 y (Bayley scales, Stanford Binet Intelligence Scale, Graham-Ernhart Block Sort Test, Wechsler Intelligence Scale for Children, Wide Range Achievement Test. The main analyses examined the relationship between neurocognitive measures and paternal or maternal age when adjusted for potential confounding factors. Advanced paternal age showed significant associations with poorer scores on all of the neurocognitive measures apart from the Bayley Motor score. The findings were broadly consistent in direction and effect size at all three ages. In contrast, advanced maternal age was generally associated with better scores on these same measures. CONCLUSIONS: The offspring of older fathers show subtle impairments on tests of neurocognitive ability during infancy and childhood. In light of secular trends related to delayed fatherhood, the clinical implications and the mechanisms underlying these findings warrant closer scrutiny.

    Aim of the study: We present the application of massively parallel sequencing (MPS) to extend the scope of analysis in a disputed paternity case. Material and methods: A standard paternity test comprising 16 autosomal STRs was performed by capillary electrophoresis (CE) using 3130xl Genetic Analyzer. Additionally, MPS was performed with ForenSeq DNA Signature Prep Kit and Illumina MiSeq FGx™ Forensic Genomics System. Paternity index (PI) was calculated using DNAStat v.2.1 software. Results>: CE revealed two mismatches, at D21S11 and VWA, between the putative father and the child. Based on MPS results, the mismatches were analyzed and a nonconsensus sequence of allele 14 at the VWA locus in the mother - child pair was identified. Different sequence variants were also detected in 16-16 homozygote alleles at the D3S1358 locus in the child. Conclusions: MPS helped to formulate a definite conclusion regarding the paternity of the defendant and provided full information on intra-allelic polymorphism.

  11. Father involvement, paternal sensitivity, and father-child attachment security in the first 3 years.

    Brown, Geoffrey L; Mangelsdorf, Sarah C; Neff, Cynthia

    2012-06-01

    To reach a greater understanding of the early father-child attachment relationship, this study examined concurrent and longitudinal associations among father involvement, paternal sensitivity, and father-child attachment security at 13 months and 3 years of age. Analyses revealed few associations among these variables at 13 months of age, but involvement and sensitivity independently predicted father-child attachment security at age 3. Moreover, sensitivity moderated the association between involvement and attachment security at 3 years. Specifically, involvement was unrelated to attachment security when fathers were highly sensitive, but positively related to attachment security when fathers were relatively less sensitive. Father involvement was also moderately stable across the two time points, but paternal sensitivity was not. Furthermore, there was significant stability in father-child attachment security from 13 months to 3 years. Secure attachment at 13 months also predicted greater levels of paternal sensitivity at 3 years, with sensitivity at age 3 mediating the association between 13 month and 3 year attachment security. In sum, a secure father-child attachment relationship (a) was related to both quantity and quality of fathering behavior, (b) remained relatively stable across early childhood, and (c) predicted increased paternal sensitivity over time. These findings further our understanding of the correlates of early father-child attachment, and underscore the need to consider multiple domains of fathers' parenting and reciprocal relations between fathering behavior and father-child attachment security.

    To investigate the association between paternal exposure to occupational electromagnetic radiation and the sex ratio of the offspring. We searched various databases, including PubMed, Embase, Cochrane Library, OVID, Bioscience Information Service (BIOSIS), China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals and Wanfang Database, for the literature relevant to the association of paternal exposure to occupational electromagnetic radiation with the sex ratio of the offspring. We conducted a meta-analysis on their correlation using Stata 11.0. There was no statistically significant difference in the sex ratio between the offspring with paternal exposure to occupational electromagnetic radiation and those without (pooled OR = 1.00 [95% CI: 0.95 -1.05], P = 0.875). Subgroup analysis of both case-control and cohort studies revealed no significant difference (pooled OR = 1.03 [95% CI: 0.99 -1.08], P = 0.104 and pooled OR = 0.98 [95% CI: 0.99 -1.08], P = 0.186, respectively). Paternal exposure to occupational electromagnetic radiation is not correlated with the sex ratio of the offspring.

    The purpose of the present study is to determine if paternal or maternal history of diabetes mellitus (DM) and hypertension (HT) contributes to the prevalence and phenotype of polycystic ovary syndrome (PCOS). We performed an epidemiologic study about PCOS from four districts in Beijing, China, between 2008 and 2009. Parental histories of DM and HT were collected, and the basic characteristics and serum indices of 123 PCOS patients and 718 non-PCOS controls were tested. The prevalence of a parental history of DM and HT was significantly higher in PCOS patients than non-PCOS women (17.1 % vs. 9.2 % and 42.3 % vs. 26.0 %, P PCOS and non-PCOS patients (odds ratio (OR) = 3.42, 95 % confidence interval (CI) = 1.69-6.91; OR = 2.50, 95 % CI = 1.58-3.93, respectively). A paternal history of both DM and HT was significantly associated with sex hormone-binding globulin, fasting plasma glucose, and fasting insulin levels, the free androgen index, and the homeostatic model assessment-insulin resistance in PCOS patients (P PCOS. PCOS patients with a positive paternal history of both DM and HT have an adverse endocrine and metabolic profile. A paternal history of DM and HT poses a risk to PCOS.

    Different genetic systems can be both the cause and the consequence of genetic conflict over the transmission of genes, obscuring their evolutionary origin. For instance, with paternal genome elimination (PGE), found in some insects and mites, both sexes develop from fertilized eggs, but in males

    Chromosomal mosaicism in human preimplantation embryos is a common cause ofspontaneous abortions, however, our knowledge of its etiology is limited. We used multicolor fluorescence in situ hybridization (FISH) painting to investigate whether paternally-transmitted chromosomal aberrations result in mosaicism in mouse 2-cell embryos. Paternal exposure to acrylamide, an important industrial chemical also found in tobacco smoke and generated during the cooking process of starchy foods, produced significant increases in chromosomally defective 2-cell embryos, however, the effects were transient primarily affecting the postmeiotic stages of spermatogenesis. Comparisons with our previous study of zygotes demonstrated similar frequencies of chromosomally abnormal zygotes and 2-cell embryos suggesting that there was no apparent selection against numerical or structural chromosomal aberrations. However, the majority of affected 2-cell embryos were mosaics showing different chromosomal abnormalities in the two blastomeric metaphases. Analyses of chromosomal aberrations in zygotes and 2-cell embryos showed a tendency for loss of acentric fragments during the first mitotic division ofembryogenesis, while both dicentrics and translocations apparently underwent propersegregation. These results suggest that embryonic development can proceed up to the end of the second cell cycle of development in the presence of abnormal paternal chromosomes and that even dicentrics can persist through cell division. The high incidence of chromosomally mosaic 2-cell embryos suggests that the first mitotic division of embryogenesis is prone to missegregation errors and that paternally-transmitted chromosomal abnromalities increase the risk of missegregation leading to embryonic mosaicism.

    Full Text Available Anxiety and stress-related disorders are severe psychiatric conditions that affect performance in daily tasks and represent a high cost to public health. The initial observation of Charles Darwin that animals and human beings share similar characteristics in the expression of emotion raise the possibility of studying the mechanisms of psychiatric disorders in other mammals (mainly rodents. The development of animal models of anxiety and stress has helped to identify the pharmacological mechanisms and potential clinical effects of several drugs. Animal models of anxiety are based on conflict situations that can generate opposite motivational states induced by approach-avoidance situations. The present review revisited the main rodent models of anxiety and stress responses used worldwide. Here we defined as “ethological” the tests that assess unlearned/unpunished responses (such as the elevated plus maze, light-dark box, and open field, whereas models that involve learned/punished responses are referred to as “conditioned operant conflict tests” (such as the Vogel conflict test. We also discussed models that involve mainly classical conditioning tests (fear conditioning. Finally, we addressed the main protocols used to induce stress responses in rodents, including psychosocial (social defeat and neonatal isolation stress, physical (restraint stress, and chronic unpredictable stress.

  4. Relationships between locus of control, trait anxiety, and state anxiety: an interactionist perspective.

    1979-06-01

    This study examined the relationships among generalized expectancy for internal or external control, situational expectancy of control over aversive stimuli, trait anxiety level, and state anxiety reactivity. Seventy-two male subjects, selected from the upper and lower halves of the distributions of scores from the I-E and STAI A-Trait Scales, were randomly assigned to one of three conditions of expectancy of control over electric shock. Repeated measures of state anxiety were taken at three points in the experiment, and subjects were asked to rate the degree of control they expected to have in avoiding shocks. Results, based upon analyses of variance, were interpreted as strongly supportive of the use of the interactionist model in understanding the manner in which personality trait and situational variables interact in the determination of subject expectancies of control and anxiety reactivity.

    State anxiety is known to affect far aiming tasks, but less is known about the effects of state anxiety on running and aiming while running. Therefore, in the current study participants ran on a treadmill at their preferred speed in a low- and high-anxiety condition. In both conditions, running was combined with dart throwing in the last minutes. Results showed that attention shifted away from task execution with elevated levels of anxiety. Furthermore, gait patterns were more conservative and oxygen uptake was higher with anxiety. In addition, performance and efficiency on the dart throwing task also decreased with anxiety. These findings are in line with attentional control theory and provide an indication that state anxiety not only affects aiming tasks but also tasks that rely heavily on the aerobic system. Moreover, findings indicate that when combined, running, aiming, and anxiety all compete for attention leading to suboptimal attentional control and possibly a decrease in performance.

  7. Psychobiology of anxiety disorders and obsessive-compulsive spectrum disorders.

    Obsessive-compulsive disorder is currently classified as an anxiety disorder. However, there is growing interest in the concept of an obsessive-compulsive spectrum of disorders (OCSDs). The relationship between anxiety disorders and OCSDs has been questioned. The psychobiology of anxiety disorders and OCSDs is briefly reviewed in this article. While there appear to be several distinct contrasts in the underlying psychobiology of these conditions, there is also evidence of overlapping mechanisms. In addition, there are crucial gaps in our current database, confounding nosological decision-making. Conceptualizing various anxiety disorders and putative OCSDs as lying within a broader spectrum of emotional disorders may be useful. However, clinicians must also recognize that individual anxiety and obsessive-compulsive spectrum conditions, including disorders characterized by body-focused repetitive behaviors, have distinct psychobiological underpinnings and require different treatment approaches.

  8. Mouse zygotes respond to severe sperm DNA damage by delaying paternal DNA replication and embryonic development.

    Directory of Open Access Journals (Sweden)

    Joanna E Gawecka

    Full Text Available Mouse zygotes do not activate apoptosis in response to DNA damage. We previously reported a unique form of inducible sperm DNA damage termed sperm chromatin fragmentation (SCF. SCF mirrors some aspects of somatic cell apoptosis in that the DNA degradation is mediated by reversible double strand breaks caused by topoisomerase 2B (TOP2B followed by irreversible DNA degradation by a nuclease(s. Here, we created zygotes using spermatozoa induced to undergo SCF (SCF zygotes and tested how they responded to moderate and severe paternal DNA damage during the first cell cycle. We found that the TUNEL assay was not sensitive enough to identify the breaks caused by SCF in zygotes in either case. However, paternal pronuclei in both groups stained positively for γH2AX, a marker for DNA damage, at 5 hrs after fertilization, just before DNA synthesis, while the maternal pronuclei were negative. We also found that both pronuclei in SCF zygotes with moderate DNA damage replicated normally, but paternal pronuclei in the SCF zygotes with severe DNA damage delayed the initiation of DNA replication by up to 12 hrs even though the maternal pronuclei had no discernable delay. Chromosomal analysis of both groups confirmed that the paternal DNA was degraded after S-phase while the maternal pronuclei formed normal chromosomes. The DNA replication delay caused a marked retardation in progression to the 2-cell stage, and a large portion of the embryos arrested at the G2/M border, suggesting that this is an important checkpoint in zygotic development. Those embryos that progressed through the G2/M border died at later stages and none developed to the blastocyst stage. Our data demonstrate that the zygote responds to sperm DNA damage through a non-apoptotic mechanism that acts by slowing paternal DNA replication and ultimately leads to arrest in embryonic development.

    Levels of reproductive skew vary in wild primates living in multimale groups depending on the degree to which high-ranking males monopolize access to females. Still, the factors affecting paternity in egalitarian societies remain unexplored. We combine unique behavioral, life history, and genetic data to evaluate the distribution of paternity in the northern muriqui (Brachyteles hypoxanthus), a species known for its affiliative, nonhierarchical relationships. We genotyped 67 individuals (22 infants born over a 3-y period, their 21 mothers, and all 24 possible sires) at 17 microsatellite marker loci and assigned paternity to all infants. None of the 13 fathers were close maternal relatives of females with which they sired infants, and the most successful male sired a much lower percentage of infants (18%) than reported for the most successful males in other species. Our findings of inbreeding avoidance and low male reproductive skew are consistent with the muriqui's observed social and sexual behavior, but the long delay (≥2.08 y) between the onset of male sexual behavior and the age at which males first sire young is unexpected. The allocation of paternity implicates individual male life histories and access to maternal kin as key factors influencing variation in paternal--and grandmaternal--fitness. The apparent importance of lifelong maternal investment in coresident sons resonates with other recent examinations of maternal influences on offspring reproduction. This importance also extends the implications of the "grandmother hypothesis" in human evolution to include the possible influence of mothers and other maternal kin on male reproductive success in patrilocal societies.

  10. Multiple song features are related to paternal effort in common nightingales.

    Sexual ornamentation may be related to the degree of paternal care and the 'good-parent' model predicts that male secondary characters honestly advertise paternal investment. In most birds, males are involved in bringing up the young and successful reproduction highly depends on male contribution during breeding. In passerines, male song is indicative of male attributes and for few species it has been shown that song features also signal paternal investment to females. Males of nightingales Luscinia megarhynchos are famous for their elaborate singing but so far there is only little knowledge on the role of male song in intersexual communication, and it is unknown whether male song predicts male parenting abilities. Using RFID technology to record male feeding visits to the nest, we found that nightingale males substantially contribute to chick feeding. Also, we analyzed male nocturnal song with focus on song features that have been shown to signal male quality before. We found that several song features, namely measures of song complexity and song sequencing, were correlated with male feeding rates. Moreover, the combination of these song features had strong predictive power for male contribution to nestling feeding. Since male nightingales are involved in chick rearing, paternal investment might be a crucial variable for female mate choice in this species. Females may assess future paternal care on the basis of song features identified in our study and thus these features may have evolved to signal direct benefits to females. Additionally we underline the importance of multiple acoustic cues for female mating decisions especially in species with complex song such as the nightingale.

    Not only are substance-use disorders and externalizing disorders frequently comorbid, they often co-occur in families across generations. The current study examined the role of genetic and environmental influences in the relationship between paternal histories of drug dependence or alcohol dependence and offspring conduct disorder using an offspring-of-twins design. Participants were male twins (n = 1,774) from the Vietnam Era Twin Registry, their offspring (n = 1,917), and mothers of the offspring (n = 1,202). Twins had a history of drug dependence, alcohol dependence, or neither. Based on the father's and his co-twin's drug-dependence or alcohol-dependence history and zygosity, risk groups were constructed to reflect different levels of genetic and environmental risk that were then used to predict offspring conduct disorder. After controlling for potentially confounding variables, the offspring of men with a history of drug dependence or alcohol dependence had significantly higher rates of conduct disorder, compared with offspring of men without this history. Offspring at higher genetic risk had higher rates of conduct disorder. High-risk offspring at lower environmental risk had lower rates of conduct disorder but only in the case of paternal drug-dependence risk. Lower environmental risk did not influence rates of offspring conduct disorder when the father had an alcohol-dependence history. Genetic risk associated with both paternal drug-dependence and paternal alcohol-dependence histories predicted offspring conduct-disorder risk, but only risk associated with paternal drug-dependence history was mitigated by having a low-risk environment. These results demonstrated a significant gene-environment interaction effect.

    Reviews findings on the relationships between locus of control and anxiety and examines these relationships for three types of anxiety measures; general trait anxiety, situation specific trait anxiety, and state anxiety. In general, findings support the existence of meaningful relationships between greater externality and higher levels of both general trait anxiety and test anxiety. It was suggested that the relation between locus of control and state anxiety is a function of the situational context in which state anxiety is measured.

    Maternal obesity exerts negative effects on cognitive function and behavior of the offspring. In the present study, we assessed the effects of paternal physical exercise on spatial learning ability in relation with hippocampal neuroplasticity in the rat pups born from the obese maternal rats. There were four experimental groups: paternal nonexercised male pups from normal maternal rats, paternal exercised male pups from normal maternal rats, paternal nonexercised male pups from obese maternal rats, and paternal exercised male pups from obese maternal rats. Normal diet was supplied for normal maternal rats and high-fat diet was supplied for obese maternal rats for a 12-week period until mating, and the same diet for each group continued throughout pregnancy and lactation period. Male rats in the exercising groups exercised for a 12-week period. Spatial learning ability was reduced in the male rat pups born from the obese maternal rats. Expressions of brain-derived neurotrophic factor (BDNF) and tyrosine kinase B receptor (TrkB) in the hippocampus were suppressed and cell proliferation and differentiation in the hippocampus were reduced in the male rat pups born from the obese maternal rats. Paternal treadmill exercise improved spatial learning ability, increased BDNF and TrkB expressions, and enhanced cell proliferation and differentiation in the male rat pups born from the obese maternal rats. It can be suggested that paternal exercise enhances hippocampal neuroplasticity and consequently improved spatial learning ability in the rat pups born from the obese maternal rats.

    Anxiety disorders are complex diseases, which often occur in combination with major depression, alcohol use disorder, or general medical conditions. Anxiety disorders were the most common mental disorders within the EU states in 2010 with 14% prevalence. Anxiety disorders are triggered by environmental factors in genetically susceptible individuals, and therefore genetic research offers a great route to unravel molecular basis of these diseases. As anxiety is an evolutionarily conserved respo...

    Anxiety disorders (generalized anxiety disorder, panic disorder/agoraphobia, social anxiety disorder, and others) are the most prevalent psychiatric disorders, and are associated with a high burden of illness. Anxiety disorders are often underrecognized and undertreated in primary care. Treatment is indicated when a patient shows marked distress or suffers from complications resulting from the disorder. The treatment recommendations given in this article are based on guidelines, meta-analyses, and systematic reviews of randomized controlled studies. Anxiety disorders should be treated with psychological therapy, pharmacotherapy, or a combination of both. Cognitive behavioral therapy can be regarded as the psychotherapy with the highest level of evidence. First-line drugs are the selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors. Benzodiazepines are not recommended for routine use. Other treatment options include pregabalin, tricyclic antidepressants, buspirone, moclobemide, and others. After remission, medications should be continued for 6 to 12 months. When developing a treatment plan, efficacy, adverse effects, interactions, costs, and the preference of the patient should be considered.

    High rates of anxiety and depression are reported among youth with autism spectrum disorders. These conditions are generally assessed using measures validated for typically developing youth. Few studies have investigated their validity for autism spectrum disorders, which is crucial for accurate assessment and the provision of proper treatment. The Revised Children's Anxiety and Depression Scale was evaluated with 67 youth with autism spectrum disorders to examine its utility in measuring anxiety and depression in this population. Parents and children (aged 11-15 years) referred to a multisite intervention study completed the Pediatric Anxiety Rating Scale, Multidimensional Anxiety Scale for Children, Anxiety Disorders Interview Schedule, Child Behavior Checklist, and Revised Children's Anxiety and Depression Scale. Results suggest acceptable internal consistency of the Revised Children's Anxiety and Depression Scale. Modest convergent validity was found among the Revised Children's Anxiety and Depression Scale and other standardized measures of anxiety and depression. There were stronger correlations between Revised Children's Anxiety and Depression Scale Total scores and subscales of measures expected to correlate significantly than those not expected to correlate. One exception was a significant association between the Revised Children's Anxiety and Depression Scale and Child Behavior Checklist Attention subscale, calling into question the divergent validity in separating anxiety from attention problems. Overall, results suggest preliminary support for the Revised Children's Anxiety and Depression Scale in youth with high-functioning autism spectrum disorders. © The Author(s) 2014.

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

    Full Text Available Objective: The study examined the effectiveness of a school-based cognitive-behavioral therapy (CBT program for school aged children with high levels of anxiety symptoms. Method: The study design was a randomized controlled trial (RCT comparing CBT to a waitlist-control condition. A total of 61 children (37 girls and 24 boys; age range 8-13 with high scores on either self-report or parental reports of anxiety participated in the study. The treatment group received 10 weekly sessions over three months that was administered using the Cool Kids treatment manual (Lyneham 2003. Outcome measures included parent-rated scales of anxiety and anxiety interference, and child self-report scales of anxiety, anxiety interference, depression and self-esteem. Both study groups were comparable at baseline for clinical and demographic variables. A mixed design ANOVA with pre-post treatment as within and CBT vs waitlist groups as between group variable was used for statistical analysis. Results: At post-test, CBT group had lower scores on anxiety, interference of anxiety and depression scales and higher scores on self-esteem scales of scholastic competence, social acceptance and behavioral conduct, but not physical appearance and athletic ability compared to the waitlist control group. Conclusions: The study presents empirical evidence for the effectiveness of a school based CBT Cool Kids program for reducing anxiety symptoms and increasing self-esteem in elementary school children. Future studies may examine the durability of treatment gains

    Pregnancy anxiety is associated with risk of preterm birth and an array of other birth, infant, and childhood outcomes. However, previous research has not helped identify those pregnant women at greatest risk of experiencing this specific, contextually-based affective condition. We examined associations between demographic, medical, and psychosocial factors and pregnancy anxiety at 24-26 weeks of gestation in a prospective, multicentre cohort study of 5271 pregnant women in Montreal, Canada. Multivariate analyses indicated that higher pregnancy anxiety was independently related to having an unintended pregnancy, first birth, higher medical risk, and higher perceived risk of complications. Among psychosocial variables, higher pregnancy anxiety was associated with lower perceived control of pregnancy, lower commitment to the pregnancy, more stressful life events, higher perceived stress, presence of job stress, lower self-esteem and more social support. Pregnancy anxiety was also higher in women who had experienced early income adversity and those who did not speak French as their primary language. Psychosocial variables explained a significant amount of the variance in pregnancy anxiety independently of demographic and medical variables. Women with pregnancy-related risk factors, stress of various kinds, and other psychosocial factors experienced higher pregnancy anxiety in this large Canadian sample. Some of the unique predictors of pregnancy anxiety match those of earlier US studies, while others point in new directions. Screening for high pregnancy anxiety may be warranted, particularly among women giving birth for the first time and those with high-risk pregnancies. © 2016 John Wiley & Sons Ltd.
