    Lack of insight complicates the evaluation and treatment of patients with psychotic and affective disorders. No studies of insight in seasonal affective disorder (SAD) have been reported. Thirty patients with SAD diagnosed by the Structured Clinical Interview for DSM-III-R but no other axis I conditions were treated short-term with light-therapy. Insight was measured with the Scale to Assess Unawareness of Mental Disorder (SUMD) as modified by the authors to assess the self-report of insight into depressive symptoms. Increasing scores (1 to 5) indicated increasing unawareness of illness (i.e., less insight). SAD patients displayed a moderate amount of insight when depressed (mean SUMD score, 2.5). When recovered, they showed no significant change in insight into past depressive symptoms (mean SUMD score, 2.8). Greater insight into current depressive symptoms correlated with more depressive symptoms on the Hamilton Rating Scale for Depression score ([HRSD] r = .35, P depressive symptoms that does not change after recovery, a result in agreement with studies of insight in psychosis and mania. Further, in SAD, increased severity of illness may be associated with increased insight into depressive symptoms, consistent with the hypothesis of depressive realism.

    Eating pathology in Seasonal Affective Disorder (SAD) may be more severe than hyperphagia during winter. Although research has documented elevated rates of subclinical binge eating in women with SAD, the prevalence and correlates of binge eating disorder (BED) in SAD remain largely uncharacterized. We examined the prevalence and correlates of binge eating, weekly binge eating with distress, and BED as defined by the DSM-IV-TR in SAD. We also tested whether binge eating exhibits a seasonal pattern among individuals with BED. Two samples were combined to form a sample of individuals with SAD (N=112). A third sample included non-depressed adults with clinical (n=12) and subclinical (n=11) BED. All participants completed the Questionnaire of Eating and Weight Patterns-Revised (QEWP-R) and modified Seasonal Pattern Assessment Questionnaire (M-SPAQ). In the SAD sample, 26.5% reported binge eating, 11.6% met criteria for weekly binge eating with distress, and 8.9% met criteria for BED. Atypical symptom severity predicted binge eating and BED. In the BED sample, 30% endorsed seasonal worsening of mood, and 26% reported a winter pattern of binge eating. The spectrum of eating pathology in SAD includes symptoms of BED, which are associated with atypical depression symptoms, but typical depression symptoms. Copyright © 2014 Elsevier Ireland Ltd.

    Seasonal affective disorder (SAD) is a subtype of recurrent depressive or bipolar disorder that is characterized by regular onset and remission of affective episodes at the same time of the year. The aim of the present study was to provide epidemiological data and data on the socioeconomic impact of SAD in the general population of Austria. We conducted a computer-assisted telephone interview in 910 randomly selected subjects (577 females and 333 males) using the Seasonal Health Questionnaire (SHQ), the Seasonal Pattern Assessment Questionnaire (SPAQ), and the Sheehan Disability Scale (SDS). Telephone numbers were randomly drawn from all Austrian telephone books and transformed using the random last digits method. The last birthday method was employed to choose the target person for the interviews. Out of our subjects, 2.5% fulfilled criteria for the seasonal pattern specifier according to DSM-5 and 2.4% (95% CI=1.4-3.5%) were diagnosed with SAD. When applying the ICD-10 criteria 1.9% (95% CI=0.9-2.8%) fulfilled SAD diagnostic criteria. The prevalence of fall-winter depression according to the Kasper-Rosenthal criteria was determined to be 3.5%. The criteria was fulfilled by 15.1% for subsyndromal SAD (s-SAD). We did not find any statistically significant gender differences in prevalence rates. When using the DSM-5 as a gold standard for the diagnosis of SAD, diagnosis derived from the SPAQ yielded a sensitivity of 31.8% and a specificity of 97.2%. Subjects with SAD had significantly higher scores on the SDS and higher rates of sick leave and days with reduced productivity than healthy subjects. Prevalence estimates for SAD with the SHQ are lower than with the SPAQ. Our data are indicative of the substantial burden of disease and the socioeconomic impact of SAD. This epidemiological data shows a lack of gender differences in SAD prevalence. The higher rates of females in clinical SAD samples might, at least in part, be explained by lower help seeking behaviour in

  13. An overview of seasonal affective disorder and its treatment options.

    Seasonal affective disorder (SAD) is defined as a history of major depressive episodes that recur regularly at a particular time of year. Depending on the diagnostic instruments and criteria available, the reported prevalence (1%-10%) varies. Neurotransmitter abnormalities have been implicated in the pathophysiology, but they do not necessarily explain the seasonal pattern or the known chronobiological abnormalities in SAD compared with nonseasonal depression. Circadian rhythm abnormalies have been hypothesized to account for these aspects of SAD, and they provide a rationale for the therapeutic use of light therapy. Family history, twin, and molecular genetics studies suggest that hereditary factors are also involved. Light therapy and antidepressant medication are effective treatment options, with limited evidence for the efficacy of psychotherapy. Some studies demonstrate that narrow-band short wavelength "blue" light, naturalistic dawn simulation, and high-density negative air ionization are effective. Patients should be informed of the benefits of diet and exercise. Light therapy should be clinically monitored in the same manner, as it is done for other antidepressant treatments.

    Research suggests that two dimensions of national culture, individualism-collectivism and power distance, predict affective responses to the seasonally varying levels of ambient sunlight that may underlie regular cycles of mood and behavior in Seasonal Affective Disorder (SAD). Specifically, negative affect is predicted by the diminished sunlight of fall-winter in countries higher in individualism and lower in power distance, and by the increased sunlight of spring-summer in countries lower in individualism and higher in power distance. This study tests whether individualism correlates positively, and power distance negatively, with the frequency of winter-SAD relative to that of summer-SAD. A search for studies reporting frequencies of both winter-SAD and summer-SAD identified 55 samples encompassing 18 countries and 38,408 participants, including 1931 with SAD. The frequency of winter-SAD, relative to that of summer-SAD, correlated positively with individualism (r=.67, p=.001) and negatively with power distance (r=-.72, p=.0001). Countries in which winter-SAD was more common than summer-SAD were significantly more individualistic and less power-distant than countries in which summer-SAD was more common than winter-SAD. Results survived various tests of threats to validity. The study is limited by the quantity, quality, diversity, and representativeness of the research under review and by its correlational design. Individualism and power distance are strongly related to the relative prevalence of winter-SAD and summer-SAD. Culture may play an important but previously overlooked role in the etiology of SAD.

    The personality traits Neuroticism and Extraversion may be involved in the development of seasonal affective disorder (SAD). However, the impact of personality traits on SAD severity and whether such self-reported traits fluctuate with season is unknown. We investigated the association between Neuroticism, as acquired in a symptom-free phase and depression severity in individuals with SAD and seasonal changes in personality traits in individuals with SAD compared to healthy controls. Twenty-nine individuals diagnosed with SAD and thirty demographically matched controls completed the NEO Personality Inventory-Revised and the Major Depression Inventory twice: in summer when individuals with SAD were symptom-free, and in winter when they experienced SAD symptoms. In summer, the groups scored similarly on their personality traits, and the controls did not score any different in winter compared to summer. High scores on Neuroticism in summer was associated with more severe depressive symptoms in winter in SAD individuals. In winter, individuals with SAD scored higher on Neuroticism and lower on Extraversion, both compared to controls and to their own summer scores. Our results support that Neuroticism may represent a vulnerability marker related to SAD, and during a depressive episode Neuroticism and Extraversion may be sensitive markers of SAD pathology.

    It is thought that variation in natural light levels affect people with Seasonal Affective Disorder (SAD). Several meteorological factors related to luminance can be forecast but little is known about which factors are most indicative of worsening SAD symptoms. The aim of this meteorological analysis is to determine which factors are linked to SAD symptoms. The symptoms of 291 individuals with SAD in and near Groningen have been evaluated over the period 2003-2009. Meteorological factors linked to periods of low natural light (sunshine, global radiation, horizontal visibility, cloud cover and mist) and others (temperature, humidity and pressure) were obtained from weather observation stations. A Bayesian zero adjusted auto-correlated multilevel Poisson model was carried out to assess which variables influence the SAD symptom score BDI-II. The outcome of the study suggests that the variable sunshine duration, for both the current and previous week, and global radiation for the previous week, are significantly linked to SAD symptoms.

    Seasonal affective disorder (SAD) is a seasonal pattern of recurrent major depressive episodes that most commonly occurs during autumn or winter and remits in spring. The prevalence of SAD ranges from 1.5% to 9%, depending on latitude. The predictable seasonal aspect of SAD provides a promising opportunity for prevention. This review - one of four reviews on efficacy and safety of interventions to prevent SAD - focuses on second-generation antidepressants (SGAs). To assess the efficacy and safety of second-generation antidepressants (in comparison with other SGAs, placebo, light therapy, melatonin or agomelatine, psychological therapies or lifestyle interventions) in preventing SAD and improving patient-centred outcomes among adults with a history of SAD. A search of the Specialised Register of the Cochrane Depression, Anxiety and Neuorosis Review Group (CCDANCTR) included all years to 11 August 2015. The CCDANCTR contains reports of randomised controlled trials derived from EMBASE (1974 to date), MEDLINE (1950 to date), PsycINFO (1967 to date) and the Cochrane Central Register of Controlled Trials (CENTRAL). Furthermore, we searched the Cumulative Index to Nursing and Allied Health Literature, Web of Knowledge, The Cochrane Library and the Allied and Complementary Medicine Database (to 26 May 2014). We also conducted a grey literature search and handsearched the reference lists of included studies and pertinent review articles. For efficacy, we included randomised controlled trials on adults with a history of winter-type SAD who were free of symptoms at the beginning of the study. For adverse events, we planned to include non-randomised studies. Eligible studies compared an SGA versus another SGA, placebo, light therapy, psychological therapy, melatonin, agomelatine or lifestyle changes. We also intended to compare SGAs in combination with any of the comparator interventions versus the same comparator intervention as monotherapy. Two review authors screened

    To explore the effects of five-element music therapy on elderly patients with seasonal affective disorder in a Chinese nursing home. The patients (n = 50) were recruited from a Shijingshan district nursing home in Beijing, China. They were randomly assigned to two groups, a treatment group and a control group, with 25 participants in each group. The patients received music therapy for 1-2 h each week over an 8-week period. The music therapy involved four phases: introduction, activities, listening to the Chinese five-element music, and a concluding phase. The participants in the control group did not listen to the five-element music. This study consisted of two parts: (a) a qualitative study that used focus groups to understand the feelings of the patients with seasonal affective disorder; (b) a quantitative study that involved administration of the self-rating depression scale (SDS) and Hamilton depression scale (HAMD) before and after treatment. (a) Qualitative analysis results: strength derived from the five-element group music therapy and emotional adjustment. The five-element group music therapy can reduce patients' psychological distress and let them feel inner peace and enhance their life satisfaction. (b) No significant difference in SDS and HAMD scores was found between the two groups (P > 0.05) prior to treatment. After treatment, the mean SDS score of the control group was 49.9 +/- 18.8, while the treatment group's score was 40.2 +/- 18.1. The HAMD score of the control group was 11.2 +/-3.1, and the treatment group's score was 8.8 +/- 4.9. Following 8 weeks of music therapy, the SDS and HAMD scores of the treatment group were significantly lower than those for the control group (P music therapy alleviated the symptoms of seasonal affective disorder in the elderly patients.

    To investigate the difference between nurses and the general population regarding seasonal variations in sleep disorders during 2004-2008. The effects of season and group interaction on sleep disorders with regard to different comorbidities were also examined. Studies on seasonal variations in sleep disorders were mainly conducted in Norway for the general population. Furthermore, whether different comorbidities cause seasonal variations in sleep disorders in nurses remains unknown. A retrospective study. Data from the Taiwan National Health Insurance Research Database were used in generalised estimating equation Poisson distribution models to investigate the differences in sleep disorders between nurses and the general population diagnosed with sleep disorders (each n = 7643) as well as the interaction effects of sleep disorders between the groups with respect to different seasons. Furthermore, the interaction effects between groups and seasons on sleep disorders in the subgroups of comorbid anxiety disorders and depressive disorders were studied. Both the nurses and the general population had fewer outpatient visits for sleep disorders in winter than in other seasons. The nurses had fewer outpatient visits for sleep disorders than the general population did in each season. The nurses had more outpatient visits for sleep disorders in winter than in summer compared with the general population in the comorbid depressive disorder subgroup but not in the comorbid anxiety disorder subgroup. Nurses and the general population exhibited similar seasonal patterns of sleep disorders, but nurses had fewer outpatient visits for sleep disorders than the general population did in each season. For nurses with comorbid depressive disorders, outpatient visits for sleep disorders were more numerous in winter than in summer, potentially because nurses with comorbid depressive disorders are affected by shorter daylight exposure during winter. Depression and daylight exposure may

    The purpose of this study was to investigate possible rapid effects of light therapy on depressed mood in patients with seasonal affective disorder. Participants received 1 hour of bright light therapy and 1 hour of placebo dim red light in a randomized order crossover design. Depressed mood was measured at baseline and after each hour of light treatment using two self-report depression scales (Profile of Mood States-Depression-Dejection [POMS-D] subscale and the Beck Depression Inventory II [BDI-II]). When light effects were grouped for the two sessions, there was significantly greater reduction in self-report depression scores by -1.3 (p = 0.02) on the BDI-II and -1.2 (p = 0.02) on the POMS-D. A significant but modest improvement was detected after a single active light session. This is the first study, to our knowledge, to document an immediate improvement with light treatment using a placebo-controlled design with a clinical sample of depressed individuals.

    Efficacious treatments for seasonal affective disorder include light therapy and a seasonal affective disorder-tailored form of cognitive-behavioral therapy. Using data from a parent clinical trial, these secondary analyses examined the relationship between cognitive change over treatment with cognitive-behavioral therapy, light therapy, or combination treatment and mood outcomes the next winter. Sixty-nine participants were randomly assigned to 6-weeks of cognitive-behavioral therapy, light therapy, or combination treatment. Cognitive constructs (i.e., dysfunctional attitudes, negative automatic thoughts, and rumination) were assessed at pre- and post-treatment. Dysfunctional attitudes, negative automatic thoughts, and rumination improved over acute treatment, regardless of modality; however, in participants randomized to solo cognitive-behavioral therapy, a greater degree of improvement in dysfunctional attitudes and automatic thoughts was uniquely associated with less severe depressive symptoms the next winter. Change in maladaptive thoughts during acute treatment appears mechanistic of solo cognitive-behavioral therapy's enduring effects the next winter, but is simply a consequence of diminished depression in light therapy and combination treatment.

    The phenomenology of dissociative disorders may be complex and sometimes confusing. We describe here two cases who were initially misdiagnosed. The first case concerned a 61 year-old woman, who was initially diagnosed as an isolated dissociative fugue and was actually suffering from severe major depressive episode. The second case concerned a 55 year-old man, who was suffering from type I bipolar disorder and polyvascular disease, and was initially diagnosed as dissociative fugue in a mooddestabilization context, while it was finally a stroke. Yet dissociative disorders as affective disorder comorbidity are relatively unknown. We made a review on this topic. Dissociative disorders are often studied through psycho-trauma issues. Litterature is rare on affective illness comorbid with dissociative disorders, but highlight the link between bipolar and dissociative disorders. The later comorbidity often refers to an early onset subtype with also comorbid panic and depersonalization-derealization disorder. Besides, unipolar patients suffering from dissociative symptoms have more often cyclothymic affective temperament. Despite the limits of such studies dissociative symptoms-BD association seems to correspond to a clinical reality and further works on this topic may be warranted. Copyright © 2014 L’Encéphale.

    To evaluate the robustness of an appearance-focused intervention to prevent skin cancer in individuals reporting seasonal affective disorder (SAD) symptoms and pathological tanning motives. Randomized, controlled clinical trial. College campus. Four hundred thirty adult female indoor tanners (200 in the intervention group and 230 control participants). A booklet discussing the history of tanning, current tanning norms, UV radiation's effects on skin, recommendations for indoor tanning use focusing on abstinence and harm reduction recommendations, and information on healthier, appearance-enhancing alternatives to tanning. Self-reported attitudes, intentions, and tanning behaviors; pathological tanning motives assessed by a questionnaire developed for this study; and SAD symptoms assessed by the Seasonal Pattern Assessment Questionnaire. Two of the 4 pathological tanning scales, opiatelike reactions to tanning and dissatisfaction with natural skin tone, were significant moderators demonstrating stronger treatment effects for individuals scoring higher on these scales. Treatment effects were equivalently positive (ie, no significant moderator effects) for all levels of SAD symptoms and all levels of the other 2 pathological tanning motive scales (ie, perceiving tanning as a problem and tolerance to the effects of tanning). The appearance-focused skin cancer prevention intervention is robust enough to reduce indoor tanning among tanners who exhibit SAD symptoms or pathological tanning motives. Tailored interventions may address individuals' motivations for tanning and their relation to maladaptive behavior, such as dissatisfaction with appearance or the need for relaxation because of anxiety.

    Full Text Available Objective. To investigate the effects of bright light treatment for secondary outcome measures and to explore and validate empirically derived subgroups and treatment effects in subgroups. Methods. A descriptive design. A sample of forty-nine persons (mean age of 45.8 with clinically assessed seasonal affective disorder (SAD or subsyndromal SAD (S-SAD participated in a two-group clinical trial evaluating the effects of treatment with bright light therapy. A person-oriented cluster analysis was applied to study treatment effects in subgroups. Results. For the merged group, sleepiness (Epworth Sleepiness Scale, fatigue (fatigue questionnaire, and health-related quality of life (SF-36 were improved at posttreatment, and results were maintained at the one-month followup. Three distinct subgroups had a high level of fatigue in common, while the level of excessive daytime sleepiness and depressed mood differed between the subgroups. Over time, all subgroups improved following ten days treatment in a light room. Conclusion. Fatigue, excessive daytime sleepiness, and health-related quality of life improve in a similar way as depressed mood following treatment with bright light. The treatment was effective irrespective of the severity of the disorder, that is, for persons with SAD and subsyndromal SAD.

    Polymorphisms in aryl hydrocarbon receptor nuclear translocator-like (ARNTL) gene, the key component of circadian clock manifests circadian rhythm abnormalities. As seasonal affective disorder (SAD) is associated with disrupted circadian rhythms, the main objective of this study was to screen an Indian family with SAD for ARNTL gene polymorphisms. In this study, 30 members of close-knit family with SAD, 30 age- and sex-matched controls of the same caste with no prior history of psychiatric illness and 30 age- and sex-matched controls belonging to 17 different castes with no prior history of psychiatric illness were genotyped for five different single nucleotide polymorphisms (SNPs) in ARNTL gene by TaqMan allele-specific genotyping assay. Statistical significance was assessed by more powerful quasi-likelihood score test-XM. Most of the family members carried the risk alleles and we observed a highly significant SNP rs2279287 (A/G) in ARNTL gene with an allelic frequency of 0.75. Polymorphisms in ARNTL gene disrupt circadian rhythms causing SAD and genetic predisposition becomes more deleterious in the presence of adverse environment.

    Obsessive-compulsive disorder (OCD) is frequently associated with mood disorders. However, to date, the co-occurrence of OCD with seasonal affective disorder (SAD) has not been investigated. We have aimed to estimate the prevalence of seasonal mood changes in patients with OCD and explore the contribution of seasonality in mood to the severity of OCD. The Seasonal Pattern Assessment Questionnaire (SPAQ), the Yale-Brown Obsession and Compulsion Scale (Y-BOCS), the Hamilton Depression Rating Scale-17 Items (HDRS-17), and the Beck Anxiety Inventory (BAI) were administered to patients with OCD (n=104) and controls (n=125). The degree of seasonality was measured by the Global Seasonality Score (GSS) calculated from the SPAQ. SAD and subsyndromal seasonal affective disorder (S-SAD) were significantly more prevalent in patients with OCD (53%, n=55) than controls (25%, n=31). When patients were assessed in the season in which SAD occurs, depression and compulsions (but not obsessions, OCD or anxiety) were more severe than those assessed in a season during which SAD does not occur. SAD frequently co-occurs with OCD and, given this co-occurrence, depression symptoms in some patients with OCD might be expected to vary on a seasonal basis. Copyright © 2016 Elsevier Ireland Ltd.

    Full Text Available Abstract Background Recent research has emphasized that the human circadian rhythm system is differentially sensitive to short wavelength light. Light treatment devices using efficient light-emitting diodes (LEDs whose output is relatively concentrated in short wavelengths may enable a more convenient effective therapy for Seasonal Affective Disorder (SAD. Methods The efficacy of a LED light therapy device in the treatment of SAD was tested in a randomized, double-blind, placebo-controlled, multi-center trial. Participants aged 18 to 65 with SAD (DSM-IV major depression with seasonal pattern were seen at Baseline and Randomization visits separated by 1 week, and after 1, 2, 3 and 4 weeks of treatment. Hamilton Depression Rating Scale scores (SIGH-SAD were obtained at each visit. Participants with SIGH-SAD of 20 or greater at Baseline and Randomization visits were randomized to active or control treatment: exposure to the Litebook LED treatment device (The Litebook Company Ltd., Alberta, Canada which delivers 1,350 lux white light (with spectral emission peaks at 464 nm and 564 nm at a distance of 20 inches or to an inactivated negative ion generator at a distance of 20 inches, for 30 minutes a day upon awakening and prior to 8 A.M. Results Of the 26 participants randomized, 23 completed the trial. Mean group SIGH-SAD scores did not differ significantly at randomization. At trial end, the proportions of participants in remission (SIGH-SAD less than 9 were significantly greater (Fisher's exact test, and SIGH-SAD scores, as percent individual score at randomization, were significantly lower (t-test, with active treatment than with control, both in an intent-to-treat analysis and an observed cases analysis. A longitudinal repeated measures ANOVA analysis of SIGH-SAD scores also indicated a significant interaction of time and treatment, showing superiority of the Litebook over the placebo condition.

    A safe and effective way to control weight in patients with affective disorders is needed, and phentermine is a possible candidate. We performed a PubMed search of articles pertaining to phentermine, sibutramine, and affective disorders. We compared the studies of phentermine with those of sibutramine. The search yielded a small number of reports. Reports concerning phentermine and affective disorders reported that i) its potency in the central nervous system may be comparatively low, and ii) it may induce depression in some patients. We were unable to find more studies on the subject; thus, it is unclear presently whether phentermine use is safe in affective disorder patients. Reports regarding the association of sibutramine and affective disorders were slightly more abundant. A recent study that suggested that sibutramine may have deleterious effects in patients with a psychiatric history may provide a clue for future phentermine research. Three explanations are possible concerning the association between phentermine and affective disorders: i) phentermine, like sibutramine, may have a depression-inducing effect that affects a specific subgroup of patients, ii) phentermine may have a dose-dependent depression-inducing effect, or iii) phentermine may simply not be associated with depression. Large-scale studies with affective disorder patients focusing on these questions are needed to clarify this matter before investigation of its efficacy may be carried out and it can be used in patients with affective disorders.

    Full Text Available This paper consists of a case history and an overview of the relationship, aetiology, and treatment of comorbid bipolar disorder migraine patients. A MEDLINE literature search was used. Terms for the search were bipolar disorder bipolar depression, mania, migraine, mood stabilizer. Bipolar disorder and migraine cooccur at a relatively high rate. Bipolar II patients seem to have a higher risk of comorbid migraine than bipolar I patients have. The literature on the common roots of migraine and bipolar disorder, including both genetic and neuropathological approaches, is broadly discussed. Moreover, bipolar disorder and migraine are often combined with a variety of other affective disorders, and, furthermore, behavioural factors also play a role in the origin and course of the diseases. Approach to treatment options is also difficult. Several papers point out possible remedies, for example, valproate, topiramate, which acts on both diseases, but no first-choice treatments have been agreed upon yet.

    Full Text Available Abstract Background Clinical symptoms of affective disorders, their response to light treatment, and sensitivity to other circadian interventions indicate that the circadian system has a role in mood disorders. Possibly the mechanisms involve circadian seasonal and photoperiodic mechanisms. Since genetic susceptibilities contribute a strong component to affective disorders, we explored whether circadian gene polymorphisms were associated with affective disorders in four complementary studies. Methods Four groups of subjects were recruited from several sources: 1 bipolar proband-parent trios or sib-pair-parent nuclear families, 2 unrelated bipolar participants who had completed the BALM morningness-eveningness questionnaire, 3 sib pairs from the GenRed Project having at least one sib with early-onset recurrent unipolar depression, and 4 a sleep clinic patient group who frequently suffered from depression. Working mainly with the SNPlex assay system, from 2 to 198 polymorphisms in genes related to circadian function were genotyped in the participant groups. Associations with affective disorders were examined with TDT statistics for within-family comparisons. Quantitative trait associations were examined within the unrelated samples. Results In NR1D1, rs2314339 was associated with bipolar disorder (P = 0.0005. Among the unrelated bipolar participants, 3 SNPs in PER3 and CSNK1E were associated with the BALM score. A PPARGC1B coding SNP, rs7732671, was associated with affective disorder with nominal significance in bipolar family groups and independently in unipolar sib pairs. In TEF, rs738499 was associated with unipolar depression; in a replication study, rs738499 was also associated with the QIDS-SR depression scale in the sleep clinic patient sample. Conclusion Along with anti-manic effects of lithium and the antidepressant effects of bright light, these findings suggest that perturbations of the circadian gene network at several levels may

    In bipolar disorder, the factors provoking a new episode are unknown. As a seasonal variation has been noticed, it has been suggested that weather conditions may play a role. The aim of the study was to elucidate whether meteorological parameters influence the development of new bipolar phases....... A group of patients with at least three previous hospitalizations for bipolar disorder was examined every 3 months for up to 3 years. At each examination an evaluation of the affective phase was made according to the Hamilton Depression Scale (HAM-D(17)), and the Bech-Rafaelsen Mania Rating Scale (MAS......). In the same period, daily recordings from the Danish Meteorological Institute were received. We found no correlations between onset of bipolar episodes [defined as MAS score of 11 or more (mania) and as HAM-D(17) score of 12 or more (depression)] and any meteorological parameters. We found a statistical...

    We tested the hypothesis that the early improvement in mood after the first hour of bright light treatment compared to control dim-red light would predict the outcome at six weeks of bright light treatment for depressed mood in patients with Seasonal Affective Disorder (SAD). We also analyzed the value of Body Mass Index (BMI) and atypical symptoms of depression at baseline in predicting treatment outcome. Seventy-eight adult participants were enrolled. The first treatment was controlled crossover, with randomized order, and included one hour of active bright light treatment and one hour of control dim-red light, with one-hour washout. Depression was measured on the Structured Interview Guide for the Hamilton Rating Scale for Depression-SAD version (SIGH-SAD). The predictive association of depression scores changes after the first session. BMI and atypical score balance with treatment outcomes at endpoint were assessed using multivariable linear and logistic regressions. No significant prediction by changes in depression scores after the first session was found. However, higher atypical balance scores and BMI positively predicted treatment outcome. Absence of a control intervention for the six-weeks of treatment (only the first session in the laboratory was controlled). Exclusion of patients with comorbid substance abuse, suicidality and bipolar I disorder, and patients on antidepressant medications, reducing the generalizability of the study. Prediction of outcome by early response to light treatment was not replicated, and the previously reported prediction of baseline atypical balance was confirmed. BMI, a parameter routinely calculated in primary care, was identified as a novel predictor, and calls for replication and then exploration of possible mediating mechanisms.

    Seasonal variation exists in the psychopathology of eating disorders. However, it is still unknown whether there is seasonal variation in eating disorder symptom severity. This study investigated seasonal trends in hospital admissions and birth dates among patients with eating disorders in Taiwan (25°N). Subgroup analyses by gender and comorbid affective disorders were also of interest. Data on all hospital admissions between 2000 and 2013 were collected from the Taiwan National Health Insurance Research Database, and 1954 patients with eating disorders were identified. Hospital admissions and birth dates were recorded by day. The four seasons and cross-seasons were defined by solstices and equinoxes. The expected distribution of births was determined using data from all patients hospitalized from 2000 to 2013 (n = 13,139,306). Hospital admissions among patients with eating disorders exceeded the rate of expected hospital admissions in the summer season (p distributions of birth dates among these patients did not differ from the expected distributions. Interestingly, hospital admissions among patients with comorbid affective disorders exceeded the rates of hospital admissions among non-affective patients during the spring (p = 0.004). Moreover, the number of non-affective patients born during autumn exceeded the birth rates of affective patients during this season (p = 0.001). Gender and comorbid affective disorders were not associated with cross-seasonal differences in either hospitalizations or dates of birth. Affective psychopathology in inpatients with eating disorders may substantially contribute to symptom severity that waxes and wanes with the seasons. Moreover, the seasonal distribution of birth dates was significantly different in patients without comorbid affective disorders.

    The high co-occurrence between borderline personality disorder and affective disorders has led many to believe that borderline personality disorder should be considered as part of an affective spectrum. The aim of the present study was to examine whether the prevalence of affective disorders are higher for patients with borderline personality disorder than for patients with other personality disorders. In a national cross-sectional study of patients receiving mental health treatment in Norway (N = 36 773), we determined whether psychiatric outpatients with borderline personality disorder (N = 1 043) had a higher prevalence of affective disorder in general, and whether they had an increased prevalence of depression, bipolar disorder or dysthymia specifically. They were compared to patients with paranoid, schizoid, dissocial, histrionic, obsessive-compulsive, avoidant, dependent, or unspecified personality disorder, as well as an aggregated group of patients with personality disorders other than the borderline type (N = 2 636). Odds ratios were computed for the borderline personality disorder group comparing it to the mixed sample of other personality disorders. Diagnostic assessments were conducted in routine clinical practice. More subjects with borderline personality disorder suffered from unipolar than bipolar disorders. Nevertheless, borderline personality disorder had a lower rate of depression and dysthymia than several other personality disorder groups, whereas the rate of bipolar disorder tended to be higher. Odds ratios showed 34% lower risk for unipolar depression, 70% lower risk for dysthymia and 66% higher risk for bipolar disorder in patients with borderline personality disorder compared to the aggregated group of other personality disorders. The results suggest that borderline personality disorder has a stronger association with affective disorders in the bipolar spectrum than disorders in the unipolar spectrum.

  1. A model for self-treatment of four sub-types of symptomatic 'depression' using non-prescription agents: neuroticism (anxiety and emotional instability); malaise (fatigue and painful symptoms); demotivation (anhedonia) and seasonal affective disorder 'SAD'.

    This article will present a model for how 'depression' (i.e. depressive symptoms) can be divided into four self-diagnosed sub-types or causes which might then be self-treated using agents available without prescription. (Another, much rarer, cause of depressed symptoms is the classical illness of 'melancholia', which when severe cannot be self-treated and typically requires hospitalization.) A self-management option and alternative is now needed due to the an inappropriate emphasis of modern psychiatry on treatment of imprecise syndromal 'disorders' which may entail treating 'depression' at the cost of making the patient feel and function worse. By contrast, the basic theoretical stance of self-management is that depressed mood should be seen as a result of unpleasant symptoms - and it is the symptoms that require treatment, not the mood itself. Furthermore, drugs (or other interventions) need to be classified in terms of their potential therapeutic effects on these symptoms that may cause depressed mood. The four common causes of depressed mood considered here are the personality trait of Neuroticism; the state of malaise (fatigue, aching etc) which accompanies an illness with an activated immune system; demotivation due to lack of positive emotions (anhedonia); and the syndrome of seasonal affective disorder (SAD). Each of the four sub-types is then 'matched' with a first-line non-prescription agent. The 'stabilizing' agents such as St John's Wort and the antihistamines chlorpheniramine and diphenhydramine are used for treatment of Neuroticism; analgesics/pain killers such as aspirin, ibuprofen, paracetamol/acetaminophen and the opiates are used to treat malaise; energizing agents such as caffeine and nicotine are used for the treatment of demotivation; and bright light used in the early morning to treat SAD. Self-treatments are intended to be used after research and experimentally, on a trial-and-error basis; with self-monitoring of beneficial and harmful

    Full Text Available Affective disorders in childhood have been more intensively studied in the last three decades. They can be recognized among the children of all ages, but are more frequent among the older children. The main characteristics of mood disorders are similar among children, adolescents and adults, although development factors affect their clinical features. Development factors affect the manifestation of all symptoms. Two main criteria for these disorders in childhood are mood disorders, such as reduced or elevated mood and irritability. These symptoms may result in social or academic damage. Depression among children is a wide-spread, family and recurrent condition, which continues episodically in adulthood. Depression is frequently associated with other psychiatric disorders, increasing the risk of suicidal behaviour, misuse of psychoactive substances and behavioural disorders. Depression in childhood brings about worse psychosocial, academic and family functioning. Family, social and environmental factors have a significant role in affective disorders of children and young people.

    Ventricular enlargement was determined using linear measurement on MR images in a total of 71 patients with affective disorders, including bipolar affective disorder (41) and depression (30). Fourty-one healthy persons served as controls. Evans ratio, Huckman number and minimum distance of caudate nuclei (MDCN) were used as indices for ventricular enlargment. No significant difference in Evans ratio was observed between both the group of bipolar affective disorder and the group of depression and the control group. Nor did it correlate with age in any of the groups. Huckman number was significantly higher in the group of bipolar affective disorder than the other two groups. It positively correlated with age in the group of depression. MDCN was significantly increased in the group of bipolar affective disorder, as compared with the control group; and there was a positive correlation between MDCN and age in both the group of dipolar affective disorder and the group of depression. In conclusion, ventricular enlargement was dependent upon aging in affetive disorder patients. This tendency was more noticeable in the group of depression. In addition, atrophy of the caudate nuclei was likely to be severer in the group of dipolar affective disorder than the group of depression. (N.K.)

  6. [Comorbidity of eating disorders and bipolar affective disorders].

    2006-01-01

    Eating disorders--anorexia nervosa, bulimia nervosa and eating disorders not otherwise specified (EDNOS) occur usually in young females. The significant pathogenic differences between patients who only restrict food, and patients with binge eating and compensatory behaviours, such as vomiting and purging were described. The prevalence of bipolar affective disorders--especially bipolar II and bipolar spectrum disorders (BS) may reach 5% in the general population. About half of the depressive episodes are associated with a "mild" bipolar disorder, and such a diagnosis is suggested by impulsivity and mood-instability. Previously, majority of research on the comorbidity between eating and affective disorders focused on depressive symptomatology, however difficulties in the reliable assessment of hypomania may obfuscate the estimation of the co-occurrence of eating disorders with BS. Epidemiological studies suggest the association between BS and eating disorders with binge episodes (bulimia nervosa, anorexia- bulimic type and EDNOS with binge episodes). Co-occurrence of such disorders with depressive symptoms probably suggests the diagnosis of BS, not recurrent depression. Bulimic behaviours, impulsivity and affective disorders might be related to the impairment of the serotonergic neurotransmission, which may result from the genetic vulnerability and early life trauma. Currently, the first-line pharmacological treatment of co-occurring eating disorders with binge episodes and BS are selective serotonin reuptake inhibitors. However in some cases, the use of mood-stabilising agents as monotherapy or in combination with serotonergic drugs may be helpful.

    Full Text Available The author analyzes researches on the study of affective disorders in arterial hypertension (AH. It is noted that AH at the present stage is considered as one of the factors of cognitive dysfunction. The article emphasizes that the analysis of comorbid relations of depression and hypertension is hardly possible without the study of affective and cardiovascular disorders at the clinical level, taking into account their dynamic characteristics and key features of the course of depressive states in general. The author considers the features of the current: post-stroke depressions, nosogenic depressions of anxious and anxious-hypochondriacally types, anxiety-phobic disorders, comorbid panic disorders, protracted depression with traits of endoreactive dysthymia, hypochondriacal disorders, panic attacks, and the like in patients with arterial hypertension. Some features of affective disorders are revealed in patients with cardiovascular disorders. It is emphasized that the increase in the effectiveness of treatment of mental disorders in patients with hypertensive encephalopathy can be solved by improving the methods of early diagnosis, developing additional screening and monitoring diagnostic tools using it in an interdisciplinary approach.

    Numerous studies have reported that admission rates in patients with affective disorders are subject to seasonal variation. Notwithstanding, there has been limited evaluation of the degree to which changeable daily meteorological patterns influence affective disorder admission rates. A handful of small studies have alluded to a potential link between psychiatric admission rates and meteorological variables such as environmental temperature (heat waves in particular), wind direction and sunshine. We used the Kruskal-Wallis test, ARIMA and time-series regression analyses to examine whether daily meteorological variables—namely wind speed and direction, barometric pressure, rainfall, hours of sunshine, sunlight radiation and temperature—influence admission rates for mania and depression across 12 regions in Ireland over a 31-year period. Although we found some very weak but interesting trends for barometric pressure in relation to mania admissions, daily meteorological patterns did not appear to affect hospital admissions overall for mania or depression. Our results do not support the small number of papers to date that suggest a link between daily meteorological variables and affective disorder admissions. Further study is needed.

  12. Affective disorders among women during post partum

    Full Text Available Women, in general, present a high rate of prevalence of affective disorders, mainly depressive ones, during their lives. This is even more evident during their puerperal time, were depression is quite common. This is, probably, due to the fact of a highest physical and emotional needs during this difficult period, for both the mother and the family,as well. This clinical condition will increase both the mobility and mortality rates among puerperal women and will increase the risk for new episodes of depression on future pregnancies. Since we all know that during puerperium, both mother and child are usually attended by the Health System, this is a good time to detect these disorders. Therefore, we will try to review the pertinent medical literature regarding this probem, in order to provide the psychiatrist and another physicians with new, effective tools, that will allow them to recognize earlier, patients with this disorder, handle them properly to avoid all negative consequences.

    2012-10-01

    Full Text Available Research on cognitive biases in depression has provided considerable evidence for the impact of emotion on cognition. Individuals with depression tend to preferentially process mood-congruent material and to show deficits in the processing of positive material leading to biases in attention, memory, and judgments. More research is needed, however, to fully understand which cognitive processes are affected. The current study further examines the impact of emotion on cognition using a priming design with facial expressions of emotion. Specifically, this study tested whether the presentation of facial expressions of emotion affects subsequent processing of affective material in participants with major depressive disorder (MDD and healthy controls (CTL. Facial expressions displaying happy, sad, angry, disgusted, or neutral expressions were presented as primes for 500ms, and participants’ speed to identify a subsequent target’s emotional expression was assessed. All participants displayed greater interference from emotional versus neutral primes, marked by slower response times to judge the emotion of the target face when it was preceded by an emotional prime. Importantly, the CTL group showed the strongest interference when happy emotional expressions served as primes whereas the MDD group failed to show this bias. These results add to a growing literature that shows that depression is associated with difficulties in the processing of positive material.

  17. Survival during the Breeding Season: Nest Stage, Parental Sex, and Season Advancement Affect Reed Warbler Survival.

    Kaja Wierucka

    Full Text Available Avian annual survival has received much attention, yet little is known about seasonal patterns in survival, especially of migratory passerines. In order to evaluate survival rates and timing of mortality within the breeding season of adult reed warblers (Acrocephalus scirpaceus, mark-recapture data were collected in southwest Poland, between 2006 and 2012. A total of 612 individuals (304 females and 308 males were monitored throughout the entire breeding season, and their capture-recapture histories were used to model survival rates. Males showed higher survival during the breeding season (0.985, 95% CI: 0.941-0.996 than females (0.869, 95% CI: 0.727-0.937. Survival rates of females declined with the progression of the breeding season (from May to August, while males showed constant survival during this period. We also found a clear pattern within the female (but not male nesting cycle: survival was significantly lower during the laying, incubation, and nestling periods (0.934, 95% CI: 0.898-0.958, when birds spent much time on the nest, compared to the nest building and fledgling periods (1.000, 95% CI: 1.00-1.000, when we did not record any female mortality. These data (coupled with some direct evidence, like bird corpses or blood remains found next to/on the nest may suggest that the main cause of adult mortality was on-nest predation. The calculated survival rates for both sexes during the breeding season were high compared to annual rates reported for this species, suggesting that a majority of mortality occurs at other times of the year, during migration or wintering. These results have implications for understanding survival variation within the reproductive period as well as general trends of avian mortality.

    Impairments in social cognition are now recognized as core illness features in psychotic and affective disorders. Despite the significant disability caused by social cognitive abnormalities, treatments for this symptom dimension are lacking. Here, we describe the evidence demonstrating abnormalities in social cognition in schizophrenia, major depressive disorder, and bipolar disorder, as well as the neurobiology of social cognition including the role of oxytocin. We then review clinical trials of oxytocin administration in psychotic and affective disorders and the impact of this agent on social cognition. To date, several studies have demonstrated that oxytocin may improve social cognition in schizophrenia; too few studies have been conducted in affective disorders to determine the effect of oxytocin on social cognition in these disorders. Future work is needed to clarify which aspects of social cognition may be improved with oxytocin treatment in psychotic and affective disorders. PMID:25153535

    Objective To test common genetic variants for association with seasonality (seasonal changes in mood and behavior) and to investigate whether there are shared genetic risk factors between psychiatric disorders and seasonality. Methods A meta-analysis of genome-wide association studies (GWAS) conducted in Australian and Amish populations in whom the Seasonal Pattern Assessment Questionnaire (SPAQ) had been administered. The total sample size was 4,156 individuals. Genetic risk scores based on results from prior large GWAS studies of bipolar disorder (BD), major depressive disorder (MDD), and schizophrenia (SCZ) were calculated to test for overlap in risk between psychiatric disorders and seasonality. Results The most significant association was with rs11825064 (p = 1.7 × 10−6, β = 0.64, S.E = 0.13), an intergenic SNP found on chromosome 11. The evidence for overlap in risk factors was strongest for SCZ and seasonality, with the SCZ genetic profile scores explaining 3% of the variance in log-transformed GSS. BD genetic profile scores were also significantly associated with seasonality, although at much weaker levels, and no evidence for overlap in risk was detected between MDD and seasonality. Conclusions Common SNPs of very large effect likely do not exist for seasonality in the populations examined. As expected, there was overlapping genetic risk factors for BD (but not MDD) with seasonality. Unexpectedly, the risk for SCZ and seasonality had the largest overlap, an unprecedented finding that requires replication in other populations, and has potential clinical implications considering overlapping cognitive deficits in seasonal affective disorders and SCZ PMID:25562672

    Full Text Available Dietary diversity score (DDS is relatively easy to measure and is shown to be a very useful indicator of the probability of adequate micronutrient intake. Dietary diversity, however, is usually assessed during a single period and little is known about the effect of seasonality on it. This study investigates whether dietary diversity is influenced by seasonality.Two cross-sectional surveys were conducted in two different seasons-dry season (October 2010 and rainy season (May 2011 among the same school-age children (SAC in two rural schools in northern Ghana. The study population consisted of 228 school-age children. A qualitative 24-hour dietary recall was conducted in both seasons. Based on 13 food groups, a score of 1 was given if a child consumed a food item belonging to a particular food group, else 0. Individual scores were aggregated into DDS for each child. Differences in mean DDS between seasons were compared using linear mixed model analysis.The dietary pattern of the SAC was commonly plant foods with poor consumption of animal source foods. The mean DDS was significantly higher (P < 0.001 in the rainy season (6.95 ± 0.55 compared to the dry season (6.44 ± 0.55 after adjusting for potential confounders such as age, sex, occupation (household head and mother and education of household head. The difference in mean DDS between dry and rainy seasons was mainly due to the difference in the consumption of Vitamin A-rich fruits and vegetables between the seasons. While vitamin A-rich fruits (64.0% vs. 0.9%; P < 0.0001 and vitamin A rich dark green leafy vegetables (52.6% vs. 23.3%, P < .0001 were consumed more during the rainy season than the dry season, more children consumed vitamin A-rich deep yellow, orange and red vegetables during the dry season than during the rainy season (73.7% vs. 36.4%, P <0.001.Seasonality has an effect on DDS and may affect the quality of dietary intake of SAC; in such a context, it would be useful to measure DDS

A total of 65 depressive patients, including 25 with BADI and 37 with BADII, were examined. 212 depressive episodes were analyzed in BAD patients, of them there were 74 with BADI and 138 with BADII. The patients with BADI took a combination of an antidepressant (AD and a normothymic (NT, NT and a neuroleptic (NL, AD, NT and NL. Those with BADII received monotherapy with AD or NL, a combination of AD + NT, AD + NL. The patients' status was clinically evaluated using a specially designed questionnaire and the MADRS and CGI psychometric scales at baseline and then at the end of 1, 2, 4, and 8 weeks of therapy.Results. The AD-containing regimens used to treat patients with BADI proved to be more effective; this therapy led to a more marked reduction in depressive symptoms (55.73% in the AD + NT-treated patients; 54.07% in the AD + NT + NL group versus 33.64% in the NT + NL-treated patients, a higher response to therapy, and a larger number of remissions by the end of the investigation (80.0, 72.7, and 33.3%, respectively. Moreover, the incidence of transient hypomanic symptoms did not significantly differ in these groups (20.0, 27.3, and 8.3%, respectively. The depressive patients with BADII generally responded better to different therapy regimens (the reduction in depressive symptoms was 52.08, 58.82, 58.40, and 53.98% in the AD, NL, AD + NT, and AD + NL groups; the remission index by the end of the investigation was 60.6, 92.9, 77.8, and 69.2%, respectively; these patients were seen to have less frequently symptoms of an antipole during their treatment (18.2, 7.1, 0.0, and 15.4%, respectively.Conclusion.

    Full Text Available Legume crops are known to have low soil N uptake early in their life cycle, which can weaken their ability to compete with other species, such as weeds or other crops in intercropping systems. However, there is limited knowledge on the main traits involved in soil N uptake during early growth and for a range of species. The objective of this research was to identify the main traits explaining the variability among legume species in soil N uptake and to study the effect of the soil mineral N supply on the legume strategy for the use of available N sources during early growth. Nine legume species were grown in rhizotrons with or without N supply. Root expansion, shoot and root biomass, nodule establishment, N2 fixation and mineral soil N uptake were measured. A large interspecific variability was observed for all traits affecting soil N uptake. Root lateral expansion and early biomass in relation to seed mass were the major traits influencing soil N uptake regardless of the level of soil N availability. Fenugreek, lentil, alfalfa, and common vetch could be considered weak competitors for soil N due to their low plant biomass and low lateral root expansion. Conversely, peanut, pea, chickpea and soybean had a greater soil N uptake. Faba bean was separated from other species having a higher nodule biomass, a higher N2 fixation and a lower seed reserve depletion. Faba bean was able to simultaneously fix N2 and take up soil N. This work has identified traits of seed mass, shoot and root biomass, root lateral expansion, N2 fixation and seed reserve depletion that allowing classification of legume species regarding their soil N uptake ability during early growth.

    Pediatric white matter disorders can be distinguished into well-defined leukoencephalopathies, and undefined leukoencephalopathies. The first category may be subdivided into: (a) hypomyelinating disorders; (b) dysmyelinating disorders; (c) leukodystrophies; (d) disorders related to cystic degeneration of myelin; and (e) disorders secondary to axonal damage. The second category, representing up to 50% of leukoencephalopathies in childhood, requires a multidisciplinar approach in order to define novel homogeneous subgroups of patients, possibly representing "new genetic disorders" (such as megalencephalic leukoencepahlopathy with subcortical cysts and vanishing white matter disease that have recently been identified). In the majority of cases, pediatric white matter disorders are inherited diseases. An integrated description of the clinical, neuroimaging and pathophysiological features is crucial for categorizing myelin disorders and better understanding their genetic basis. A review of the genetic disorders affecting white matter in the pediatric age, including some novel entities, is provided. Copyright 2004 Wiley-Liss, Inc.

    Bipolar disorder is a chronic psychiatric disease with a high prevalence and is a major psychosocial and medical burden. The exact etiological pathways of bipolar disorder are not fully understood. Genetic factors are known to play an important role in the etiology of bipolar disorder. However, high rates of discordance among identical twins and a growing body of evidence that environmental factors such as early stress can influence the onset and course of psychiatric diseases underline the importance of additional etiological mechanisms of bipolar disorders. There has been little investigation about early trauma in bipolar disorder. The aim of this study was to review the literature on the association between early traumatic interactions like child neglect, mistreatment, abuse or early parental separation and the occurrence of bipolar disorder in adulthood or impact on the course of the disease. Studies investigating associations between child neglect, mistreatment, abuse or early parental separation and occurrence of bipolar disorder in adulthood or impact on the course of the disease were searched in the Pubmed database. More than 700 articles were sorted independently by two of the authors using predefined criteria. Only research articles, reviews and meta-analyses were selected for this review. 53 articles met the inclusion criteria. To date, four systematic reviews partially addressed our research question. Early trauma is more frequently found in the past of bipolar patients than in the general population.

    Full Text Available Abstract Background We aimed at studying the seasonal changes in mood and behaviour, the distribution of hospital admissions by season, and the persistence of the circadian type in twins with bipolar disorder and their healthy co-twins. Methods All Finnish like-sex twins born from 1940 to 1969 were screened for a diagnosis of bipolar type I disorder. The diagnosis was assessed with a structured research interview, and the study subjects (n = 67 filled in the Seasonal Pattern Assessment Questionnaire (SPAQ and the Morningness-Eveningness Questionnaire (MEQ. For studying the persistence of the habitual sleep length and circadian type, we used data derived from the Finnish Twin Cohort Questionnaire (FTCQ. Bipolar twins were compared with their healthy co-twins. Results Bipolar twins had greater seasonal changes in sleep length (p = 0.01 and mood (p = 0.01, and higher global seasonality scores (p = 0.03 as compared with their co-twins with no mental disorder. Sunny days (p = 0.03 had a greater positive effect on wellbeing in the bipolar than healthy co-twins. Conclusions Our results support the view that bipolar disorder is sensitive to the environmental influence in general and to the seasonal effect in specific. Exposure to natural light appears to have a substantial effect on wellbeing in twins with bipolar disorder.

    The current study's main goal was to examine whether affective instability is elevated among individuals suffering from avoidant personality disorder (APD) by comparing it to the affective instability found among individuals suffering from borderline personality disorder (BPD) as well that found among healthy controls. Adults (N = 152, aged 18-65 years) with BPD, APD, or no psychopathology participated in a 3-week computerized diary study. We examined temporal instability in negative affect using experience-sampling methods. Both within and between days, individuals with APD showed greater affective instability compared to the healthy control individuals, although less affective instability compared to individuals with BPD. The findings are in line with affective instability (or emotional lability) as a key dimension relevant across personality disorders. Additionally, they emphasize the need for research and clinical attention to affective characteristics (alongside the more readily recognized interpersonal characteristics) of APD.

    , and that these trade-offs may render hosts less capable of concurrently mounting effective Th1-type immune responses against anthrax. This study is one of the first to examine laboratory-demonstrated Th1-Th2 trade-offs in a natural system. It provides evidence that seasonally bound pathogens may affect, through immunology, transmission dynamics of pathogens that might otherwise not be seasonally distributed. It suggests that, by manipulating the internal host ecosystem, GI parasites may influence the external ecosystem by affecting the dynamics of another environmentally transmitted pathogen.

    reduced secretion of corticotropin releasing factor may result in pathological hypoarousal and an enhanced hypothalamic-pituitary-adrenal negative feedback. Patients with atypical depression, seasonal affective disorder and chronic fatigue syndrome fall in this category. METHOD: The literature data on the overlap between the key-words were reviewed, summarized and discussed. RESULTS: Many studies suggest that these conditions themselves overlap biologically, showing hypofunction of central corticotropin releasing factor neuronal systems. CONCLUSIONS: Therefore, in the real world of clinical practice, patients often present in a grey area between classical idiopathic fatigue and early chronic atypical depression and/or seasonal depression. This underscores the potential common biological links underpinning common sympton clusters not only between depression (atypical and seasonal and chronic fatigue syndrome, but also other conditions characterized by the hypothalamic-pituitary-adrenal axis mainly diminished the corticotropin realising factor activity.

  17. Theoretical and clinical overview of affective temperaments in mood disorders

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available Temperaments are imperturbable variations of personality, traits and ways of reacting to the environment that characterize individuals and remain constant throughout several different situations. Temperaments usually play a central role in determining emotional reactions, therefore several temperamental models have attempted to establish the potential relationship between temperaments and affective disorders. According to Hagop Akiskal, affective temperaments are subclinical and subaffective trait-like manifestations of affective disorders. Unlike several models of temperament which were exclusively developed theoretically in order to describe healthy human functioning, later extrapolated to capture the pathological domains of mental and behavioral features, the current model of affective temperaments was developed on classical traditions and mainly based on the observation of subjects with mood disorders and their healthy first degree relatives. There is accumulating evidence concerning the development of affective temperaments based on their adaptive evolutionary characteristics and genetic background, and normative data from large national studies on general and healthy samples indicate their universal characteristics. Studies in affective patient populations indicate that the relationship between affective temperaments and affective illness is more complex than a simple extrapolation from psychopathology and mental health, and affective temperaments may represent a latent state of the staging model, playing a pathoplastic role in mood disorders determining their evolution, clinical features, main characteristics and outcome. A large body of data on affective temperaments has been published during the last decade, deserving a critical analysis presented in this overview.

    Full Text Available BACKGROUND: Empirical tests that link temperature-mediated changes in behaviour (activity and resource selection to individual fitness or condition are currently lacking for endotherms yet may be critical to understanding the effect of climate change on population dynamics. Moose (Alces alces are thought to suffer from heat stress in all seasons so provide a good biological model to test whether exposure to non-optimal ambient temperatures influence seasonal changes in body mass. Seasonal mass change is an important fitness correlate of large herbivores and affects reproductive success of female moose. METHODOLOGY/PRINCIPAL FINDINGS: Using GPS-collared adult female moose from two populations in southern Norway we quantified individual differences in seasonal activity budget and resource selection patterns as a function of seasonal temperatures thought to induce heat stress in moose. Individual body mass was recorded in early and late winter, and autumn to calculate seasonal mass changes (n = 52 over winter, n = 47 over summer. We found large individual differences in temperature-dependent resource selection patterns as well as within and between season variability in thermoregulatory strategies. As expected, individuals using an optimal strategy, selecting young successional forest (foraging habitat at low ambient temperatures and mature coniferous forest (thermal shelter during thermally stressful conditions, lost less mass in winter and gained more mass in summer. CONCLUSIONS/SIGNIFICANCE: This study provides evidence that behavioural responses to temperature have important consequences for seasonal mass change in moose living in the south of their distribution in Norway, and may be a contributing factor to recently observed declines in moose demographic performance.

  3. Analysis of affective disorders in patients with vascular dementia

    2012-01-01

    Full Text Available The outpatient records of 147 patients followed up for diagnosed vascular dementia were analyzed to assess the relationship between affective disorders and severe cognitive impairments. It was found that 7% of the examinees had a history of depressive states. Estimating the development time for vascular dementia could divide the patients into 2 groups: 1 60% of the patients in whom cognitive impairments began to determine its clinical picture just within the first 2 years after identification of affective disorders and 2 40%, in whom cognitive impairments occurred 10—20 years later. In both groups, mental disorders occurred at an equal age in the presence of depressive disorders; in Group 1, vascular dementia developed nearly twice as often as that in Group 2. At the same time, the occurrence of cognitive impairments in Group 1 patients just in the early disease stages is indicative of the organic genesis of affective disorders, as confirmed by the moderately rapid progression of psychopathological symptoms, such as sharpening of personality traits, increased rigidity of psychic processes, emotional lability, variations in affective symptomatology, inadequate remissions, and the presence of neurological symptoms. Another type of a ratio of depressive to severe cognitive disorders was found in the elderly persons in Group 2. The long existence of affective disorders without signs of cognitive diminution leads one to say that they have recurrent depressive disorder with further addition of a comorbid vascular process. These patients showed a fairly high severity of affective pathology that was responsible for more frequent admissions, as well as a phase course with relatively pure remissions without any clear intellectual-mnestic reduction and a predominance of hysterical character traits.

    psychiatry for two reasons. The first is that psychiatry seems to be so focused on the brain-its biochemistry and pharmacology--that questions of mind and soul have become rare and almost negligible. The second is to follow the course of the results of our own clinical investigations that have taken us into that very human world where questions of physical pain, psychological pain, and the experience of suffering abound. Today, however, the strategy of neuromodulation offers the advantage of being precisely tailored in neuroanatomical terms and, even more importantly, of being altogether reversible. At both our own Istituto Neurologico C. Besta and many other neurosurgical centers worldwide, many procedures have been reported in which implant neuromodulation devices successfully treat pain. For example, long-term stimulation of the spinal cord has been fairly effective in the treatment of neuropathic pain, multiple sclerosis, and various other forms of pain. Good results have been obtained in treating peripheral vascular diseases and sympathetic reflex dystrophy syndrome. Good results have also been achieved in trigeminal nerve stimulation and peripheral nerve stimulation. In the case of thalamic stimulation, there has also been an improvement of symptoms, but a long-term degree of tolerance was noticed. Hypothalamic stimulation has also been seen to be effective in controlling trigeminal autonomic cephalalgic pain, as well as the facial pain that is known to occur in multiple sclerosis. Motor cortex stimulation was found to occasionally have good results in treating neuropathic pain, whereas occipital nerve stimulation was found to achieve good results in controlling chronic cluster headache and other chronic headaches, although with only short-term follow-up so far. Recent reports of functional magnetic resonance imaging have prompted us to propose exciting new neurosurgical targets that may be effective in treating psychoaffective disorders. Our results appear to be more

    Abstract: The carbon dioxide (CO2) emissions released from biomass burning significantly affect the temporal variations of atmospheric CO2 concentrations. Based on a long-term (July 2009-June 2015) retrieved datasets by the Greenhouse Gases Observing Satellite (GOSAT), the seasonal cycle and interannual variations of column-averaged volume mixing ratios of atmospheric carbon dioxide (XCO2) in four fire affected continental regions were investigated. The results showed Northern Africa had the largest seasonal variations after removing its regional long-term trend of XCO2 with peak-to-peak amplitude of 6.2 ppm within the year, higher than central South America (2.4 ppm), Southern Africa (3.8 ppm) and Australia (1.7 ppm). The detrended regional XCO2 was found to be positively correlated with the fire CO2 emissions during fire activity period and negatively correlated with vegetation photosynthesis activity with different seasonal variabilities. Northern Africa recorded the largest change of seasonal variations of detrended XCO2 with a total of 12.8 ppm during fire seasons, higher than central South America, Southern Africa and Australia with 5.4 ppm, 6.7 ppm and 2.2 ppm, respectively. During fire episode, the positive detrended XCO2 was noticed during June-November in central South America, December-June in Northern Africa, May-November in Southern Africa. The Pearson correlation coefficients between the variations of detrended XCO2 and fire CO2 emissions from GFED4 (Global Fire Emissions Database v4) achieved best correlations in Southern Africa (R=0.77, p<0.05). Meanwhile, Southern Africa also experienced a significant negative relationship between the variations of detrended XCO2 and vegetation activity (R=-0.84, p<0.05). This study revealed that fire CO2 emissions and vegetation activity contributed greatly to the seasonal variations of GOSAT XCO2 dataset.

    There is an urgent recognized need for conservation of tropical forest deer. In order to identify some environmental factors affecting conservation, we analyzed the seasonal habitat use of two Indonesian deer species, Axis kuhlii in Bawean Island and Muntiacus muntjak in south-western Java Island, in response to several physical, climatic, biological, and anthropogenic variables. Camera trapping was performed in different habitat types during both wet and dry season to record these elusive species. The highest number of photographs was recorded in secondary forest and during the dry season for both Bawean deer and red muntjac. In models, anthropogenic and climatic variables were the main predictors of habitat use. Distances to cultivated area and to settlement were the most important for A. kuhlii in the dry season. Distances to cultivated area and annual rainfall were significant for M. muntjak in both seasons. Then we modelled their predictive range using Maximum entropy modelling (Maxent). We concluded that forest landscape is the fundamental scale for deer management, and that secondary forests are potentially important landscape elements for deer conservation. Important areas for conservation were identified accounting of habitat transformation in both study areas.

    Seizure disorder and developmental disorder are two of the most common chronic disorders in childhood. Data on perceived parental burden and specific effects on daily life is scarce. We performed a structured interview, consecutively talking to all parents of pediatric outpatients of our university hospital diagnosed with seizure or developmental disorder. Three hundred seven parents (of 317 affected children: 53 with seizure disorder, 44 with specific developmental disorder, 35 with learning disorder, 71 with intellectual disability, 15 with seizure + specific developmental disorder, 23 with seizure + learning disorder, 76 with seizure disorder + intellectual disability) were interviewed. Parents of children with both seizure disorder and intellectual disability stated the highest constraints in daily life, regarding friends, hobbies, emotional pressure, occupation, partnership, habitation, and financial burden. Due to diagnosis of seizure or developmental disorder, 155/307 (51%) parents reduced their working hours/stopped working, 62/307 (20%) changed their habitation, and 46/307 (15%) broke up. As judged by parents, 148/317 (47%) children are being discriminated against, even own family/friends and educators are held responsible. Parents perceive changes in their daily life and discrimination of their children due to their children's seizure and developmental disorders. An intellectual disability combined with seizure disorder caused the highest constraint. What is Known: • Seizure and/or developmental disorders of children may adversely influence quality of life for affected parents. • Caring for a child with special health care needs can take complete attention and own parental needs may therefore be difficult to meet. What is New: • Two out of three parents stated changes of their daily life such as quitting work, change of habitation, or breakup of partnership due to their child's diagnosis. • As judged by the parents, one in two children with

    BACKGROUND: Studies of the effect of comorbid alcoholism on the risk of recurrence in affective disorder have given contradictory results. METHOD: Using survival analysis, the rate of recurrence was calculated in a case register study including all hospital admissions with primary affective...... an auxiliary diagnosis of alcoholism. Patients with a current auxiliary diagnosis of alcoholism had increased rate of recurrence following the first three affective episodes but not following subsequent episodes compared with patients without auxiliary diagnoses. The effect of alcoholism declined...... with the number of episodes. In contrast, no effect was found of other auxiliary diagnoses on the rate of recurrence. CONCLUSION: Rehospitalisation data suggest that concurrent alcoholism increases the risk of recurrence of affective episodes during the initial course of unipolar and bipolar disorder but has...

    Full Text Available Neuropeptide Y (NPY, a neuropeptide highly conserved throughout evolution, is present at high levels in the central nervous system (CNS, as well as in peripheral tissues such as the gut and cardiovascular system. The peptide exerts its effects via multiple receptor subtypes, all belonging to the G-protein-coupled receptor superfamily. Of these subtypes, the Y1 and the Y2 are the most thoroughly characterized, followed by the Y5 subtype. NPY and its receptors have been shown to be of importance in central regulation of events underlying, for example, affective disorders, drug/alcohol use disorders, and energy homeostasis. Furthermore, within the CNS, NPY also affects sleep regulation and circadian rhythm, memory function, tissue growth, and plasticity. The potential roles of NPY in the etiology and pathophysiology of mood and anxiety disorders, as well as alcohol use disorders, have been extensively studied. This focus was prompted by early indications for an involvement of NPY in acute responses to stress, and, later, also data pointing to a role in alterations within the CNS during chronic, or repeated, exposure to adverse events. These functions of NPY, in addition to the peptide’s regulation of disease states, suggest that modulation of the activity of the NPY system via receptor agonists/antagonists may be a putative treatment mechanism in affective disorders as well as alcohol use disorders. In this review, we present an overview of findings with regard to the NPY system in relation to anxiety and stress, acute as well as chronic; furthermore we discuss post-traumatic stress disorder and, in part depression. In addition, we summarize findings on alcohol use disorders and related behaviors. Finally, we briefly touch upon genetic as well as epigenetic mechanisms that may be of importance for NPY function and regulation. In conclusion, we suggest that modulation of NPY-ergic activity within the CNS, via ligands aimed at different receptor

    Coping styles may influence the perceived life stress experienced by an individual and, therefore, also be critical in the development of affective disorders. This study examined whether familial risk of affective disorder is associated with the use of maladaptive coping styles, in healthy...... individuals. One hundred twelve high-risk and 78 low-risk individuals were identified through nation-wide registers and invited to participate in an extensive psychiatric evaluation including the Coping Inventory for Stressful Situations. The high-risk individuals used more Emotion-oriented (p = 0.......001) and Avoidance coping (p = 0.04) than individuals not at risk. Adjusted for gender, age, years of education, and recent stressful life events the high-risk individuals used more emotion-oriented coping (p = 0.03). In conclusion, maladaptive coping style may represent a trait marker for mood disorder improving...

    2015-01-01

    In this naturalistic study we adopt the lens of interpersonal theory to examine between-and within-person differences in dynamic processes of daily affect and interpersonal behaviors among individuals (N = 101) previously diagnosed with personality disorders who completed daily diaries over the course of 100 days. Dispositional ratings of interpersonal problems and measures of daily stress were used as predictors of daily shifts in interpersonal behavior and affect in multilevel models. Results indicate that ~40%–50% of the variance in interpersonal behavior and affect is due to daily fluctuations, which are modestly related to dispositional measures of interpersonal problems but strongly related to daily stress. The findings support conceptions of personality disorders as a dynamic form of psychopathology involving the individuals interacting with and regulating in response to the contextual features of their environment.

    Full Text Available An increasing number of findings confirm the significance of cerebellum in affecting regulation and early learning. Most consistent findings refer to association of congenital vermis anomalies with deficits in nonmotor functions of cerebellum. In this paper we presented a young woman who was treated since sixteen years of age for polysubstance abuse, affective instability, and self-harming who was later diagnosed with borderline personality disorder. Since the neurological and neuropsychological reports pointed to signs of cerebellar dysfunction and dysexecutive syndrome, we performed magnetic resonance imaging of brain which demonstrated partially developed vermis and rhombencephalosynapsis. These findings match the description of cerebellar cognitive affective syndrome and show an overlap with clinical manifestations of borderline personality disorder.

    Although now commonly used in medicine, the updated "disorders of sex development" (DSD) nomenclature formally introduced in 2006 has never been universally accepted by members of the affected community, particularly advocacy groups. Use of this nomenclature by medical professionals may unintentionally negatively affect access to healthcare and research for individuals with DSD conditions. Among individuals affected by various DSD diagnoses, this study sought to (1) evaluate attitudes towards potentially controversial DSD terminology, (2) determine potential impact of terminology on how affected individuals access healthcare, and (3) explore alternate terms. A web-based survey was developed in collaboration with the AIS-DSDSG (Androgen Insensitivity Syndrome-DSD Support Group) leadership. AIS-DSDSG members (caregivers and affected individuals) were surveyed about attitudes towards DSD, potential impact on healthcare utilization, and alternate terms. A qualitative analysis of reasons for using/avoiding specific terms was performed. Surveys were completed by 202 out of 580 (35%) AIS-DSDSG members (61% affected, 39% caregivers; 16% non-gender binary; age range of affected individuals 0-86 years). Only 24% use disorder of sex development to describe themselves/their child. A majority (69%) had a negative emotional experience because of clinical use of nomenclature; 81% changed their care because of it. Preferred and non-preferred terms for clinical care and research are illustrated in the figure. Preferred diagnostic terms were intersex, variation in sex development, and difference of sex development (55%, 52%, and 50% liked/strongly liked, respectively). Disorder of sex development was not preferred (17% liked/strongly liked). About one-third reported that they would not attend a clinic named the Disorder of Sex Development Clinic. Overall, 81% provided qualitative comments; flexible terminology use was a key theme. These study findings are consistent with previous

    The history of the temperament concept begins in ancient Greece. The humoral theory remained influential over the centuries. At the beginning of the 20 th century, both Wilhelm Wundt and his pupil Emil Kraepelin formulated new aspects. Wundt described two dimensions: "speed of variability of emotions" and "intensity of emotions". Kraepelin observed four fundamental states (depressive, manic, irritable and cyclothymic), which he linked to manic-depressive illness. Since then different lines of temperament research have evolved: (1) psychiatric-psychopathological theories (e. g. Ewald, Kretschmer and Sheldon), which tend to see temperament as a dilution of full-blown affective disorders; (2) neurobiological theories (e. g. Pavlov, Eysenck and Gray), which understand temperament as determined by underlying neurobiological processes - especially levels of arousal; and (3) developmental theories (e. g. Chess & Thomas, Rothbart and Kagan), which derived their temperament concept from early childhood observations. Recent theories (e. g. those of Cloninger or Akiskal) combine different aspects. After reviewing the historical temperament concepts we present underlying factors which are linked to affective disorders (such as emotional reactivity, cyclicity or trait affectivity). Finally, we illustrate the importance of temperament concepts for research in affective disorders.

    Full Text Available Jacqueline M Walsh, Lynsey A Atkinson, Sarah A Corlett, Gurprit S Lall Medway School of Pharmacy, University of Kent, Chatham, Kent, UK Abstract: The field of chronobiology has vastly expanded over the past few decades, bringing together research from the fields of circadian rhythms and sleep. The importance of the environmental day–night cycle on our health is becoming increasingly evident as we evolve into a 24-hour society. Reducing or changing sleep times against our natural instincts to rest at night has a detrimental impact on our well-being. The mammalian circadian clock, termed "the suprachiasmatic nucleus", is responsible for synchronizing our behavioral and physiological outputs to the environment. It utilizes light transcoded by specialized retinal photoreceptors as its cue to set internal rhythms to be in phase with the light–dark cycle. Misalignment of these outputs results in symptoms such as altered/disturbed sleep patterns, changes in mood, and physical and mental exhaustion – symptoms shared by many affective clinical disorders. Key links to circadian abnormalities have been found in a number of disorders, such as seasonal affective disorder, nonseasonal depression, and bipolar affective disorder. Furthermore, therapies developed through chronobiological research have been shown to be beneficial in the treatment of these conditions. In this article, we discuss the impact of circadian research on the management of affective disorders, giving evidence of how a misaligned circadian system may be a contributor to the symptoms of depression and how moderating circadian rhythms with light therapy benefits patients.

    2013-08-01

    Full Text Available Introduction: In the last years there is a great interest for the theory of the “psychotic continuum”, which accepts that there is a transition between schizophrenia and affective pathology, including bipolar disorder with psychotic interferences and the recently introduced diagnosis of schizoaffective disorder. There are few studies that analyze bipolar disorder with mood-incongruent psychosis. The purpose of this study was to observe the way in which the interference of mood-incongruent psychotic symptoms can influence the long term evolution of patients diagnosed with bipolar disorder and the similarities that exists between this type of pathology and schizoaffective disorder. Material and methods: Sixty subjects were selected, who are now diagnosed with schizoaffective disorder and bipolar disorder, with and without psychotic features. All cases have at least 15 years of evolution since the first episode of psychosis and were analyzed in term of their age of onset and longitudinal evolution. Results: The results showed that bipolar patients who had mood incongruent psychotic symptoms had an earlier age of onset and a higher rate of hospitalizations in their long term evolution compared to bipolar patients without psychotic features, which brings them closer to patients with schizoaffective disorder in term of their pattern of evolution. Conclusions: This study has demonstrated that the interference of mood-incongruent psychosis with bipolar disorder determines a worse prognosis of this disease, very similar with the evolution of patients with schizoaffective disorder

    Full Text Available Photosynthetically Active Radiation (PAR and Ultraviolet Radiation (UVR of the solar spectrum affect microalgae directly and modify the toxicity of phytotoxic compounds present in water. As a consequence seasonal variable PAR and UVR levels are likely to modulate the toxic pressure of contaminants in the field. Therefore the present study aimed to determine the toxicity of two model contaminants, the herbicides diuron and Irgarol®1051, under simulated irradiance conditions mimicking different seasons. Irradiance conditions of spring and autumn were simulated with a set of Light Emitting Diodes (LEDs. Toxicity of both herbicides was measured individually and in a mixture by determining the inhibition of photosystem II efficiency (ΦPSII of the marine flagellate Dunaliella teriolecta using Pulse Amplitude Modulation (PAM fluorometry. Toxicity of the single herbicides was higher under simulated spring irradiance than under autumn irradiance and this effect was also observed for mixtures of the herbicides. This irradiance dependent toxicity indicates that herbicide toxicity in the field is seasonally variable. Consequently toxicity tests under standard light conditions may overestimate or underestimate the toxic effect of phytotoxic compounds.

    This is a review of psychosomatic interactions between affective disorders (depressive and anxiety disturbances, irritable mood) and endocrine disease. Particular reference is made to stressful life events in the pathogenesis of endocrine disease, psychopathology of hormonal disturbances, and pathophysiology of hypothalamic-pituitary-adrenal axis function in depression and Cushing's disease. These psychosomatic interactions may lead to appraisal of common etiological mechanisms in endocrine and psychiatric disorders, of the value of retaining the category of organic affective syndromes in psychiatric classification, and of the need for research on quality-of-life measures in endocrine disease. The establishment of "psychoendocrine units," where both endocrinologists and psychiatrists should work, is advocated. Such psychoendocrine units may serve and benefit clinical populations who currently defy traditional medical subdivisions.

    Full Text Available It is known in the literature that the incidence and prevalence of suicide and attempted suicide in psychiatric patients is significantly higher than in the general population. The paper examined risk factors for suicidal behavior in the category of admitted patients hospitalized with the diagnosis of sleep disorders and affective (Unipolar resp. Bipolar depression. Study activated by 80 patients, 40 in both diagnostic groups received treatment at the Special Psychiatric Hospital in Gornja Toponica near Nis. The work methodology used are: psychiatric interview, Hamilton Depression Rating Scale (HAMD, and the C-SSRS (Columbia-Suicide Severity Rating Scale- assessment tool that assesses suicidal ideation and behavior. The study results show that there is a relationship between suicidal behavior (suicide attempts and suicidal ideation and the diagnosis of bipolar affective disorder, positive history of previous suicide attempts, so that these factors are stronger, to the degree of suicidality higher. On this sample, clearly suicidal behavior, with the same purpose, intensity of suicidal thoughts and medical impairment after suicide attempts were significantly more frequent in patients with Bipolar Affective Disorder in the depressive phase of the illness. Patients with a previous suicide attempt, and poor personal and social circumstances had a higher rate of attempted suicide.

  16. Seasonal Influences on Ground-Surface Water Interactions in an Arsenic-Affected Aquifer in Cambodia

    Millions of people in South and Southeast Asia consume drinking water daily which contains dangerous levels of arsenic exceeding health-based recommendations [1]. A key control on arsenic mobilization in aquifers in these areas has been controversially identified as the interaction of 'labile' organic matter contained in surface waters with groundwaters and sediments at depth [2-4], which may trigger the release of arsenic from the solid- to aqueous-phase via reductive dissolution of iron-(hyr)oxide minerals [5]. In a field site in Kandal Province, Cambodia, which is an arsenic-affected area typical to others in the region, there are strong seasonal patterns in groundwater flow direction, which are closely related to monsoonal rains [6] and may contribute to arsenic release in this aquifer. The aim of this study is to explore the implications of the high susceptibility of this aquifer system to seasonal changes on potential ground-surface water interactions. The main objectives are to (i) identify key zones where there are likely ground-surface water interactions, (ii) assess the seasonal impact of such interactions and (iii) quantify the influence of interactions using geochemical parameters (such as As, Fe, NO3, NH4, 14C, 3T/3He, δ18O, δ2H). Identifying the zones, magnitude and seasonal influence of ground-surface water interactions elucidates new information regarding potential locations/pathways of arsenic mobilization and/or transport in affected aquifers and may be important for water management strategies in affected areas.

    Full Text Available Chinese goral (Naemorhedus griseus are a threatened species in Thailand and the focus of captive breeding for possible reintroduction. However, little is known of their biology or what factors in the captive environment affect welfare. Our objective was to determine the impact of gender, season, and management on goral adrenal activity. We hypothesized that differences in fecal glucocorticoid concentrations would be related to animal density. Fecal samples were collected 3 days/week for 1 year from 63 individuals (n = 32 males, 31 females at two facilities that house the majority of goral in Thailand: Omkoi Wildlife Sanctuary (Omkoi, an off-exhibit breeding center that houses goral in individual pens (16 pens; n = 8 males, 8 females and in small family groups (8 pens; n = 8 males, 8 females; and the Chiang Mai Night Safari (NS, a zoo that maintains 31 goral (n = 17 males, 14 females in one large pen. Glucocorticoid metabolite concentrations were higher in male than female goral at Omkoi throughout the year, and there was a seasonal effect on adrenal activity (p<0.05. Goral at Omkoi and NS were used to test the effect of animal density on fecal glucocorticoid excretion of goral housed in similar-sized enclosures. Overall, the highest levels were found at NS (n = 31 adults/pen; 27 m2 per animal compared to Omkoi (n = 2 adults/pen; 400 m2 per animal (p<0.05. Overall findings support our hypothesis that animal density and aspects of the captive environment impact adrenal steroid activity in captive goral. In addition, gender and season also had significant effects on glucocorticoid metabolite production. Potential stressors pertaining to the welfare of this species were identified, which will guide future efforts to improve management and create self-sustaining and healthy populations of this threatened species.

    Global environmental changes affect not only the aboveground but also the belowground components of ecosystems. The effects of seasonal drought and air warming on the genus level richness of Collembola, and on the abundance and biomass of the community of Collembola and mites were studied in an acidic and a calcareous forest soil in a model oak-ecosystem experiment (the Querco experiment) at the Swiss Federal Research Institute WSL in Birmensdorf. The experiment included four climate treatments: control, drought with a 60% reduction in rainfall, air warming with a seasonal temperature increase of 1.4 °C, and air warming + drought. Soil water content was greatly reduced by drought. Soil surface temperature was slightly increased by both the air warming and the drought treatment. Soil mesofauna samples were taken at the end of the first experimental year. Drought was found to increase the abundance of the microarthropod fauna, but reduce the biomass of the community. The percentage of small mites (body length ≤ 0.20 mm) increased, but the percentage of large mites (body length >0.40 mm) decreased under drought. Air warming had only minor effects on the fauna. All climate treatments significantly reduced the richness of Collembola and the biomass of Collembola and mites in acidic soil, but not in calcareous soil. Drought appeared to have a negative impact on soil microarthropod fauna, but the effects of climate change on soil fauna may vary with the soil type.

    To study difficulties in emotional functioning in two mental disorders that have been associated with difficulties in identifying and modulating emotions: borderline personality disorder (BPD) and somatoform disorder (SoD). In 472 psychiatric inpatients, difficulties in emotional functioning were measured using the Bermond-Vorst Alexithymia Questionnaire. Profiles of difficulties in emotional functioning were identified, suggesting that patients diagnosed with BPD with or without SoD were more likely to report difficulty identifying emotions and less likely to report reduced ability to fantasize or 'pensée opératoire' (externally oriented thinking) than patients diagnosed with SoD only and patients with mixed anxiety and affective disorders. SoD patients were more likely to report reduced ability to phantasize or pensée opératoire than difficulty identifying emotions. Patients with mixed anxiety and affective disorders were more likely to report reduced ability to experience emotions than patients diagnosed with BPD and/or SoD. By using a finer-grained perspective on difficulties in emotional functioning some evidence was found for the existence of cognitive-emotional profiles that may provide more clinically relevant information than alexithymia as just a unitary construct. Further research on cognitive-emotional profiles of difficulties in emotional functioning is needed to advance the understanding, diagnosis and treatment of mental disorders. Copyright © 2012 S.

    Bipolar disorder has the highest rate of suicide of all the psychiatric disorders. In unipolar depression, individuals report vivid, affect-laden images of suicide or the aftermath of death (flashforwards to suicide) during suicidal ideation but this phenomenon has not been explored in bipolar disorder. Therefore the authors investigated and compared imagery and verbal thoughts related to past suicidality in individuals with bipolar disorder (n = 20) and unipolar depression (n = 20). The study used a quasi-experimental comparative design. The Structured Clinical Interview for DSM-IV was used to confirm diagnoses. Quantitative and qualitative data were gathered through questionnaire measures (e.g., mood and trait imagery use). Individual interviews assessed suicidal cognitions in the form of (i) mental images and (ii) verbal thoughts. All participants reported imagining flashforwards to suicide. Both groups reported greater preoccupation with these suicide-related images than with verbal thoughts about suicide. However, compared to the unipolar group, the bipolar group were significantly more preoccupied with flashforward imagery, rated this imagery as more compelling, and were more than twice as likely to report that the images made them want to take action to complete suicide. In addition, the bipolar group reported a greater trait propensity to use mental imagery in general. Suicidal ideation needs to be better characterized, and mental imagery of suicide has been a neglected but potentially critical feature of suicidal ideation, particularly in bipolar disorder. Our findings suggest that flashforward imagery warrants further investigation for formal universal clinical assessment procedures. © 2011 John Wiley and Sons A/S.

    The effects of human disturbance on biodiversity can be mediated by environmental conditions, such as water availability, climate and nutrients. In general, disturbed, dry or nutrient-depleted soils areas tend to have lower taxonomic diversity. However, little is known about how these environmental conditions affect functional composition and intraspecific variability in tropical dry forests. We studied a seasonally dry tropical forest (SDTF) under chronic anthropogenic disturbance (CAD) along rainfall and soil nutrient gradients to understand how these factors influence the taxonomic and functional composition. Specifically we evaluated two aspects of CAD, wood extraction and livestock pressure (goat and cattle grazing), along soil fertility and rainfall gradients on shrub and tree traits, considering species turnover and intraspecific variability. In addition, we also tested how the traits of eight populations of the most frequent species are affected by wood extraction, livestock pressure, rainfall and soil fertility. In general, although CAD and environmental gradients affected each trait of the most widespread species differently, the most abundant species also had a greater variation of traits. Considering species turnover, wood extraction is associated with species with a smaller leaf area and lower investment in leaf mass, probably due to the indirect effects of this disturbance type on the vegetation, i.e. the removal of branches and woody debris clears the vegetation, favouring species that minimize water loss. Livestock pressure, on the other hand, affected intraspecific variation: the herbivory caused by goats and cattle promoted individuals which invest more in wood density and leaf mass. In this case, the change of functional composition observed is a direct effect of the disturbance, such as the decrease of palatable plant abundance by goat and cattle herbivory. In synthesis, CAD, rainfall and soil fertility can affect trait distribution at community

    Post-traumatic stress disorder (PTSD) is overrepresented among cigarette smokers. It has been hypothesized that those with PTSD smoke to alleviate negative affect and counteract deficient positive affect commonly associated with the disorder; however, limited research has examined associations between PTSD symptoms, smoking motives, and affective vulnerability factors. In the current study, we examined (1) whether PTSD symptoms were associated with positive reinforcement and negative reinforcement smoking motives; and (2) whether two affective vulnerability factors implicated in PTSD-anxiety sensitivity and anhedonia-mediated relationships between PTSD symptoms and smoking motives. Data were drawn from a community sample of non-treatment-seeking smokers recruited without regard for trauma history (N = 342; 10+ cig/day). We used the Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C) to assess overall PTSD symptom severity as well as individual PTSD subfactors. Overall, PTSD symptom severity was significantly associated with negative reinforcement, but not positive reinforcement, smoking motives. Variation in anxiety sensitivity significantly mediated the relation between PTSD symptom severity and negative reinforcement smoking motives, whereas anhedonia did not. Regarding PTSD subfactors, emotional numbing was the only PTSD subfactor associated with smoking rate, while re-experiencing symptoms were uniquely associated with both positive reinforcement and negative reinforcement smoking motives. Findings suggest that anxiety sensitivity may be an important feature associated with PTSD that enhances motivation to smoke for negative reinforcement purposes. Smoking cessation interventions that alleviate anxiety sensitivity and enhance coping with negative affect may be useful for smokers with elevated PTSD symptoms. © American Academy of Addiction Psychiatry.

    Profound deafness is a lifelong impairment, leading to the physical disability as well as poor psychological adjustment. We herein present a mental health disorder rarely seen among the patients of profound deafness. A 16-year deaf and dumb girl, previously treated for depression, presented with unusual laughter, irritability, flight of ideas, decreased sleep, ideas of self importance, and decreased social functioning and educational performance. These problems were understood by the parents via sign language, who interpreted them to the interviewer. Her Young Mania Rating Scale (YMRS) score was 19 and Brief Psychiatric Rating Scale (BPRS) score was 52. She was diagnosed as a case of bipolar affective disorder (BPAD). Marked improvement in the symptoms and social and educational performance was noted after two weeks of the treatment with sodium valproate, resperidone and clonazepam. Treatment options were explained to the patient with risks and benefits, and she was involved in the decision-making. This case report highlights the importance of accurately diagnosing and managing a rare mental health disorder among the physically handicapped people, especially those who cannot communicate effectively and explain their unusual subjective experiences.

    Full Text Available Background: Although affect dysregulation is considered a core component of borderline personality disorder (BPD and somatoform disorders (SoD, remarkably little research has focused on the prevalence and nature of affect dysregulation in these disorders. Also, despite apparent similarities, little is known about how dysfunctional under- and overregulation of affect and positive and negative somatoform and psychoform dissociative experiences inter-relate. Prior studies suggest a clear relationship between early childhood psychological trauma and affect dysregulation, especially when the caretaker is emotionally, sexually, or physically abusing the child, but how these relate to under- and overregulation while differentiating for developmental epochs is not clear. Although an elevated risk of childhood trauma exposure or complex posttraumatic stress disorder (CPTSD symptoms has been reported in BPD and SoD, trauma histories, dysfunctional affect regulation, dissociation, PTSD, and CPTSD were never assessed in unison in BPD and/or SoD. Method: BPD and/or SoD diagnoses were confirmed or ruled out in 472 psychiatric inpatients using clinical interviews. Dysfunctional under- and overregulation of affect and somatoform and psychoform dissociation, childhood trauma-by-primary-caretaker (TPC, PTSD, and CPTSD were all measured using self reports. Results: No disorder-specific form of dysfunctional affect regulation was found. Although both BPD and SoD can involve affect dysregulation and dissociation, there is a wide range of intensity of dysfunctional regulation phenomena in patients with these diagnoses. Evidence was found for the existence of three qualitatively different forms of experiencing states: inhibitory experiencing states (overregulation of affect and negative psychoform dissociation most commonly found in SoD, excitatory experiencing states (underregulation of affect and positive psychoform dissociation most commonly found in BPD, and

    The prevalence of psychiatric disorders is increasing worldwide, which underscores the importance of increasing research in this field, in terms of better detection, prevention based on improvement of lifestyle and diet, and effectiveness of treatment. Increasing evidence suggest that diet and exercise can affect proper neuronal development and physiology and protect the brain from neurological illnesses or injuries. Of note, cocoa, tea, and coffee are being actively investigated because they are rich in (poly)phenolic compounds that can modulate mental health, namely brain plasticity, behavior, mood, depression, and cognition. We here systematically review human studies conducted on tea, cocoa, and coffee as related to affective disorders such as depression and anxiety. We carried out a systematic literature search in April 2016, using MEDLINE, on data from the last 10 years. After screening 955 articles, we selected 17 articles that met the criteria of being human studies and that used whole foods or their components. The results of our systematic review indicate that consumption of tea, cocoa, or coffee might have protective effects against depression. Even though this is encouraging, it should be underscored that the near totality of the current evidence comes from observational studies. Ad-hoc human trials and mechanistic, basic science studies are needed before we can provide sound advice to the public. Copyright © 2016 Elsevier B.V. All rights reserved.

    A strong association has been established between migraine and depression. However, this is the first study to differentiate in a large sample of migraine patients for symptom dimensions of the affective disorder spectrum. Migraine patients (n=3174) from the LUMINA (Leiden University Medical Centre Migraine Neuro-analysis Program) study and patients with current psychopathology (n=1129), past psychopathology (n=477), and healthy controls (n=561) from the NESDA (Netherlands Study of Depression and Anxiety) study, were compared for three symptom dimensions of depression and anxiety. The dimensions -lack of positive affect (depression specific); negative affect (nonspecific); and somatic arousal (anxiety specific)- were assessed by a shortened adaptation of the Mood and Anxiety Symptom Questionnaire (MASQ-D30). Within the migraine group, the association with migraine specific determinants was established. Multivariate regression analyses were conducted. Migraine patients differed significantly (pmigraine patients were predominantly similar to the past psychopathology group. For the somatic arousal dimension, migraine patients scores were more comparable with the current psychopathology group. Migraine specific determinants for high scores on all dimensions were high frequency of attacks and cutaneous allodynia during attacks. This study shows that affective symptoms in migraine patients are especially associated with the somatic arousal component. Copyright © 2015 Elsevier Inc. All rights reserved.

    Ecological momentary assessment (EMA; Stone & Shiffman, 1994) was utilized to examine affective instability (AI) in the daily lives of outpatients with borderline personality disorder (BPD; n=78) with and without posttraumatic stress disorder (PTSD). A psychiatric control group (n=50) composed of outpatients with major depressive disorder/dysthymia (MDD/DYS) was employed to compare across subgroups: BPD-only, BPD+PTSD, MDD/DYS-only, and MDD/DYS+PTSD. Compared to the BPD-only group, the BPD+PTSD group had significantly greater instability of fear and sadness, but did not significantly differ in instability of hostility or aggregate negative affect. This pattern of elevated instability of fear and sadness was not present—and, in fact, was reversed—in the MDD/DYS group. Results emphasize the importance of examining AI within the context of specific comorbidities and affect types. Treatment and research addressing AI in the context of BPD-PTSD comorbidity may benefit from a focus on fear and sadness as separate from hostility or general negative affect. PMID:26904388

  11. Similar photoperiod-related birth seasonalities among professional baseball players and lesbian women with an opposite seasonality among gay men: Maternal melatonin may affect fetal sexual dimorphism.

    2014-05-30

    Based on pre-mid-20th-century data, the same photoperiod-related birth seasonality previously observed in schizophrenia was also recently found in neural-tube defects and in extreme left-handedness among professional baseball players. This led to a hypothesis implicating maternal melatonin and other mediators of sunlight actions capable of affecting 4th-embryonic-week developments including neural-tube closure and left-right differentiation of the brain. Here, new studies of baseball players suggest that the same sunlight actions could also affect testosterone-dependent male-female differentiation in the 4-month-old fetus. Independently of hand-preferences, baseball players (n=6829), and particularly the stronger hitters among them, showed a unique birth seasonality with an excess around early-November and an equally significant deficit 6 months later around early-May. In two smaller studies, north-American and other northern-hemisphere born lesbians showed the same strong-hitter birth seasonality while gay men showed the opposite seasonality. The sexual dimorphism-critical 4th-fetal-month testosterone surge coincides with the summer-solstice in early-November births and the winter-solstice in early-May births. These coincidences are discussed and a "melatonin mechanism" is proposed based on evidence that in seasonal breeders maternal melatonin imparts "photoperiodic history" to the newborn by direct inhibition of fetal testicular testosterone synthesis. The present effects could represent a vestige of this same phenomenon in man. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Restricted interests are a class of repetitive behavior in autism spectrum disorders (ASD) whose intensity and narrow focus often contribute to significant interference with daily functioning. While numerous neuroimaging studies have investigated executive circuits as putative neural substrates of repetitive behavior, recent work implicates affective neural circuits in restricted interests. We sought to explore the role of affective neural circuits and determine how restricted interests are distinguished from hobbies or interests in typical development. We compared a group of children with ASD to a typically developing (TD) group of children with strong interests or hobbies, employing parent report, an operant behavioral task, and functional imaging with personalized stimuli based on individual interests. While performance on the operant task was similar between the two groups, parent report of intensity and interference of interests was significantly higher in the ASD group. Both the ASD and TD groups showed increased BOLD response in widespread affective neural regions to the pictures of their own interest. When viewing pictures of other children's interests, the TD group showed a similar pattern, whereas BOLD response in the ASD group was much more limited. Increased BOLD response in the insula and anterior cingulate cortex distinguished the ASD from the TD group, and parent report of the intensity and interference with daily life of the child's restricted interest predicted insula response. While affective neural network response and operant behavior are comparable in typical and restricted interests, the narrowness of focus that clinically distinguishes restricted interests in ASD is reflected in more interference in daily life and aberrantly enhanced insula and anterior cingulate response to individuals' own interests in the ASD group. These results further support the involvement of affective neural networks in repetitive behaviors in ASD. © 2013 The

    Full Text Available The broad construct of empathy incorporates both cognitive and affective dimensions. Recent evidence suggests that the subjects with Autistic Spectrum disorder (ASD show a significant impairment in empathic ability. The aim of this study was to evaluate the cognitive and affective components of empathy in adolescents with ASD compared to controls. Fifteen adolescents with ASD and fifteen controls underwent paper and pencil measures and a computerized Multifaceted Empathy Test. All measures were divided into Mentalizing and Experience sharing abilities. Adolescents with ASD compared to controls showed deficits in all mentalizing measures: they were incapable of interpreting and understanding the mental and emotional states of other people. Instead, in the sharing experience measures, the adolescents with ASD were able to empathize with the emotional experience of other people when they express emotions with positive valence, but were not able to do so when the emotional valence is negative. These results were confirmed by the computerized task. In conclusion, our results suggest that adolescents with ASD show a difficulty in cognitive empathy, whereas the deficit in affective empathy is specific for the negative emotional valence.

    Oxcarbazepine, a keto derivative of the 'mood stabiliser' carbamazepine, may have efficacy in the treatment of acute episodes of bipolar disorder. Potentially, it may offer pharmacokinetic advantages over carbamazepine. To review the efficacy and acceptability of oxcarbazepine compared to placebo and other agents in the treatment of acute bipolar episodes including mania, mixed episodes and depression. Electronic databases were searched up to 2 September 2011. Specialist journals and conference proceedings were handsearched. Authors, experts in the field and pharmaceutical companies were contacted requesting information on published and unpublished trials. Randomised controlled trials (RCTs) which compared oxcarbazepine with placebo or alternative agents, where the stated intent of intervention was the acute treatment of bipolar affective disorder were sought. Participants with bipolar disorder of either sex and of all ages were included. Data were extracted from the original reports individually by two review authors. For dichotomous data, odds ratios (ORs) were calculated with 95% confidence intervals (CI). Continuous data were analysed using standardised mean differences (with 95% CI). Seven studies were included in the analysis (368 participants in total). All were on mania, hypomania, mixed episodes or rapid-cycling disorder. Overall, their methodological quality was relatively low.There was no difference in the primary outcome analysis - a fall of  50% or more on the Young Mania Rating Scale (YMRS) - between oxcarbazepine and placebo (N=1, n=110, OR =2.10, 95% CI 0.94 to 4.73) in one study, conducted in children; no studies were available in adult participants.In comparison with other mood stabilisers, there was no difference between oxcarbazepine and valproate as an antimanic agent using the primary outcome (50% or more fall in YMRS, OR=0.44, 95% CI 0.10 to 1.97, 1 study, n=60, P=0.273) or the secondary outcome measure (differences in YMRS between the two

    Full Text Available Normothymic, antidepressant and antipsychotic pharmaceutics are, in accordance with international guidelines, employed both in the therapy and the prevention of bipolar disorder (BD. Long-term studies on the mechanisms of action of such medications, as well as on the pathogenetic background of BD, have led to the discovery of effective, albeit unconventional pharmacotherapeutic approaches. These methods have the potential to successfully treat mania and depression, as well as to counter affective episode relapse. Allopurinol - commonly used to treat gout, secondary hyperuricemia and Lesch-Nyhan syndrome, acts by inhibiting the synthesis of uric acid, levels of which are often increased in manic patients. Due to this, an evaluation of the potential effect of allopurinol on the reduction of mania symptoms seems to be reasonable. Additionally, the numerable research papers coming out of research regarding the role of purine neurotransmitters in mood alterations, indicate that adenosine agonists act analogously to dopamine antagonists.

  17. A cholinergic hypothesis of the unconscious in affective disorders.

    Full Text Available The interactions between distinct pharmacological systems are proposed as a key dynamic in the formation of unconscious memories underlying rumination and mood disorder, but also reflect the plastic capacity of neural networks that can aid recovery. An inverse and reciprocal relationship is postulated between cholinergic and monoaminergic receptor subtypes. M1-type muscarinic receptor transduction facilitates encoding of unconscious, prepotent behavioural repertoires at the core of affective disorders and ADHD. Behavioural adaptation to new contingencies is mediated by the classic prototype receptor: 5-HT1A (Gi/o and its modulation of m1-plasticity. Reversal of learning is dependent on increased phasic activation of midbrain monoaminergic nuclei and is a function of hippocampal theta. Acquired hippocampal dysfunction due to abnormal activation of the hypothalamic-pituitary-adrenal (HPA axis predicts deficits in hippocampal-dependent memory and executive function and further impairments to cognitive inhibition. Encoding of explicit memories is mediated by Gq/11 and Gs signalling of monoamines only. A role is proposed for the phasic activation of the basal forebrain cholinergic nucleus by cortical projections from the complex consisting of the insula and claustrum. Although controversial. recent studies suggest a common ontogenetic origin of the two structures and a functional coupling. Lesions of the region result in loss of motivational behaviour and familiarity based judgements. A major hypothesis of the paper is that these lost faculties result indirectly, from reduced cholinergic tone.

    Plague, a zoonotic disease caused by the bacterium Yersinia pestis, causes high rates of mortality in prairie dogs (Cynomys spp.). An oral vaccine against plague has been developed for prairie dogs along with a palatable bait to deliver vaccine and a biomarker to track bait consumption. We conducted field trials between September 2009 and September 2012 to develop recommendations for bait distribution to deliver plague vaccine to prairie dogs. The objectives were to evaluate the use of the biomarker, rhodamine B, in field settings to compare bait distribution strategies, to compare uptake of baits distributed at different densities, to assess seasonal effects on bait uptake, and to measure bait uptake by nontarget small mammal species. Rhodamine B effectively marked prairie dogs' whiskers during these field trials. To compare bait distribution strategies, we applied baits around active burrows or along transects at densities of 32, 65, and 130 baits/ha. Distributing baits at active burrows or by transect did not affect uptake by prairie dogs. Distributing baits at rates of ≥65/ha (or ≥1 bait/active burrow) produced optimal uptake, and bait uptake by prairie dogs in the autumn was superior to uptake in the spring. Six other species of small mammals consumed baits during these trials. All four species of tested prairie dogs readily consumed the baits, demonstrating that vaccine uptake will not be an obstacle to plague control via oral vaccination.

    Objectives: To investigate the relationship of exposure to a traumatic event and the subsequent onset of Posttraumatic Stress Disorder (PTSD) in the population exposed to floods in Pakistan. Study Design: Cross sectional study. Place and duration of study: Individuals exposed to the 2010 flood in district Shadadkot, Sindh from April 2012 to September 2012. Methodology: Sample of the study comprised of 101 individuals from the flood affected areas in Pakistan. Age range of the participants was 15 to 50 years (M=27.73, SD = 7.19), with participation of both males and females. PTSD was assessed by using the self report measure, impact of Event Scale (IES) and the subjective and objective experience to flood was assessed through Flood Related Exposure Scale (FRES) devised by the authors. Results: The prevalence rate of PTSD among the flood affected population was 35.5%. Trauma had significant positive relation with objective flood exposure and subjective flood exposure (r=.27 and r =.38) respectively. Inverse relation appeared between age and PTSD (r=-.20). PTSD was higher among females as compared to males. Conclusion: Understanding the prevalence of PTSD helps the mental health professionals in devising intervention strategies. A longitudinal study design is recommended that may be developed for better understanding of trajectories of trauma response across time span. Our findings may help identify populations at risk for treatment research. (author)

    Full Text Available Objective: Temperament originates in the brain structure, and individual differences are attributable to neural and physiological function differences. It has been suggested that temperament is associated with metabolic syndrome (MetS markers, which may be partly mediated by lifestyle and socioeconomic status. Therefore, we aim to compare MetS prevalence between different affective temperamental profiles for each season in bipolar patients. Methods: Twenty-six bipolar type-I patients of a specialized outpatient mood disorder unit were evaluated for MetS according to new definition proposed by the International Diabetes Federation in the four seasons of a year. Temperament was assessed using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego - autoquestionnaire version (TEMPS-A. Results: The proportions of MetS were 19.2, 23.1, 34.6, and 38.5% in the summer, fall, spring, and winter, respectively. Only depressive temperament scores were higher (p = 0.002 during the winter in patients with MetS. Conclusion: These data suggest that depressive temperament profiles may predispose an individual to the development of MetS in the winter.

    Bipolar disorder (BD) is a severe, familial psychiatric condition. Progress in understanding the aetiology of BD has been hampered by substantial phenotypic and genetic heterogeneity. We sought to mitigate these confounders by studying a multi-generational family multiply affected by BD and major depressive disorder (MDD), who carry an illness-linked haplotype on chromosome 4p. Within a family, aetiological heterogeneity is likely to be reduced, thus conferring greater power to detect illness-related changes. As accumulating evidence suggests that altered DNA methylation confers risk for BD and MDD, we compared genome-wide methylation between (i) affected carriers of the linked haplotype (ALH) and married-in controls (MIs), (ii) well unaffected haplotype carriers (ULH) and MI, (iii) ALH and ULH and (iv) all haplotype carriers (LH) and MI. Nominally significant differences in DNA methylation were observed in all comparisons, with differences withstanding correction for multiple testing when the ALH or LH group was compared to the MIs. In both comparisons, we observed increased methylation at a locus in FANCI, which was accompanied by increased FANCI expression in the ALH group. FANCI is part of the Fanconi anaemia complementation (FANC) gene family, which are mutated in Fanconi anaemia and participate in DNA repair. Interestingly, several FANC genes have been implicated in psychiatric disorders. Regional analyses of methylation differences identified loci implicated in psychiatric illness by genome-wide association studies, including CACNB2 and the major histocompatibility complex. Gene ontology analysis revealed enrichment for methylation differences in neurologically relevant genes. Our results highlight altered DNA methylation as a potential mechanism by which the linked haplotype might confer risk for mood disorders. Differences in the phenotypic outcome of haplotype carriers might, in part, arise from additional changes in DNA methylation that converge on

    Self-esteem (SE) and social adjustment (SA) are often impaired during the course of affective disorders; this impairment is associated with suicidal behaviour. The aim of the present study was to investigate SE and SA in unipolar or bipolar patients in relation to demographic and clinical characteristics, especially the presence of suicidality (ideation and/or attempt). Forty-four patients, 28 bipolar and 16 unipolar, in remission for at least 3 months, and 50 healthy individuals were examined through a structured clinical interview. SE and SA were assessed by the Rosenberg self-esteem scale and the social adjustment scale, respectively. The results have shown that bipolar patients did not differ from controls in terms of SE, while unipolar patients had lower SE than bipolars and controls. No significant differences in the mean SA scores were found between the three groups. Suicidality during depression was associated only in bipolar patients with lower SE at remission; similar but not as pronounced was the association of suicidality with SA. It is concluded that low SE lasting into remission seems to be related to the expression of suicidality during depressive episodes of bipolar patients, while no similar pattern is evident in unipolar patients.

    Coastal areas are impacted by multiple natural and anthropogenic processes and experience stronger pH fluctuations than the open ocean. These variations can weaken or intensify the ocean acidification signal induced by increasing atmospheric pCO2. The development of eutrophication-induced hypoxia intensifies coastal acidification, since the CO2 produced during respiration decreases the buffering capacity in any hypoxic bottom water. To assess the combined ecosystem impacts of acidification and hypoxia, we quantified the seasonal variation in pH and oxygen dynamics in the water column of a seasonally stratified coastal basin (Lake Grevelingen, the Netherlands). Monthly water-column chemistry measurements were complemented with estimates of primary production and respiration using O2 light-dark incubations, in addition to sediment-water fluxes of dissolved inorganic carbon (DIC) and total alkalinity (TA). The resulting data set was used to set up a proton budget on a seasonal scale. Temperature-induced seasonal stratification combined with a high community respiration was responsible for the depletion of oxygen in the bottom water in summer. The surface water showed strong seasonal variation in process rates (primary production, CO2 air-sea exchange), but relatively small seasonal pH fluctuations (0.46 units on the total hydrogen ion scale). In contrast, the bottom water showed less seasonality in biogeochemical rates (respiration, sediment-water exchange), but stronger pH fluctuations (0.60 units). This marked difference in pH dynamics could be attributed to a substantial reduction in the acid-base buffering capacity of the hypoxic bottom water in the summer period. Our results highlight the importance of acid-base buffering in the pH dynamics of coastal systems and illustrate the increasing vulnerability of hypoxic, CO2-rich waters to any acidifying process.

    Seasonal spring peaks of suicide are highly replicated, but their origin is poorly understood. As the peak of suicide in spring could be a consequence of decompensation of mood disorders in spring, we hypothesized that prior history of mood disorders is predictively associated with suicide in spring. We analyzed the monthly rates of suicide based upon all 37,987 suicide cases in the Danish Cause of Death Registry from 1970 to 2001. History of mood disorder was obtained from the Danish Psychiatric Central Register and socioeconomical data from the Integrated Database for Labour Market Research. The monthly rate ratio of suicide relative to December was estimated using a Poisson regression. Seasonality of suicide between individuals with versus without hospitalization for mood disorders was compared using conditional logistic regression analyses with adjustment for income, marital status, place of residence, and method of suicide. A statistically significant spring peak in suicide was observed in both groups. A history of mood disorders was associated with an increased risk of suicide in spring (for males: RR=1.18, 95% CI 1.07-1.31; for females: RR=1.20, 95% CI 1.10-1.32). History of axis II disorders was not analyzed. Danish socioeconomical realities have only limited generalizability. The results support the need to further investigate if exacerbation of mood disorders in spring triggers seasonal peaks of suicide. Identifying triggers for seasonal spring peaks in suicide may lead to uncovering novel risk factors and therapeutic targets for suicide prevention. 2009 Elsevier B.V. All rights reserved.

    Determining the presence of cortical release signs associated with white matter damage, is a clinically easy method to perform. The objective of this study is to determine the presence of cortical release signs in patients with mental illnesses and cerebrovascular disease, as well as its clinical usefulness, given that it indicates cortical damage. A review was made of cortical release signs in patients hospitalized in clinical psychiatry and general hospitals with bipolar affective disorder (40), depression (37), schizophrenia (33), cardiovascular disease (33) and dementia (37). The signs of cortical release do not have the same importance as cortical damage. For example, the glabellar reflex was found in all the groups, that of paratonia, particularly in the group with schizophrenia, and others signs in the group of patients with dementia. It is suggested that these signs imply subcortical white matter damage. The appearance of these signs shows the need for a follow up of patients diagnosed with bipolar affective disorder, depression and schizophrenia.

    2014-02-01

    This study examines whether parents of children with developmental disorders are at risk of elevated allostatic load relative to control parents and whether positive affect moderates difference in risk. In all, 38 parents of children with developmental disorders and 38 matched comparison parents were analyzed. Regression analyses revealed a significant interaction between parent status and positive affect: parents of children with developmental disorders had lower allostatic load when they had higher positive affect, whereas no such association was evident for comparison parents. The findings suggest that promoting greater positive affect may lower health risks among parents of children with developmental disorders.

  10. Disorder affects judgements about a neighbourhood: police presence does not

    Full Text Available Many police forces operate a policy of high visibility in disordered neighbourhoods with high crime. However, little is known about whether increased police presence influences people’s beliefs about a neighbourhood’s social environment or their fear of crime. Three experimental studies compared people’s perceptions of social capital and fear of crime in disordered and ordered neighbourhoods, either with a police presence or no police presence. In all studies, neighbourhood disorder lowered perceptions of social capital, resulting in a higher fear of crime. Police presence or absence had no significant effect. The pervasive effects of disorder above other environmental cues are discussed.

  11. Emotionally Responsive Wearable Technology and Stress Detection for Affective Disorders.

    As humans, we are born with no knowledge of odour. Our sense of smell is linked directly to the limbic system, the emotional part of our brain responsible for memory and behaviour, and therefore, our individual sense of smell is based purely on life's deep experiences and impressions. The roots of "Aromatherapy" can be traced back more than 3,500 years, to a time when essential oils were first recorded in human history for their therapeutic and medicinal properties. However, in the 21 st century, it remains one of the most controversial complementary therapies applied in medicine because of its pseudoscience connotations and limited available data on health benefits, despite the importance of smell on human health. Here I introduce the concept of "eScent", an emotionally responsive wearable technology that picks up on your emotions and vital signs and sends a personalisable 'scent bubble' to your nose. It combines sensing and dispensing aromatics for immersive experiences and multiple health benefits. It presents an empowering, sensory intervention and resilience builder that emits mood-enhancing aromas in a controllable way, depending on biofeedback. The advantage of essential oils merged with biometric sensors and intelligent tracking devices (e.g. an Apple Watch), could lead to a new palette of scents that are bio-synchronized to an individual's emotional, mental, and/or physical state and in a real-time manner alleviate high levels of stress, thus preventing the risk of a serious mental ill health relapse. Closure of the loop with wearable scent delivery systems requires an innovative, creative and collaborative approach, crossing many disciplines in psychological related sciences, biotechnology and industrial design. Testing such hypotheses in translational human studies is a matter of future research which could not only lead to valuable "prodromal" interventions for psychiatry, but new stress management tools for people suffering from affective disorders.

    2012-06-01

    Associations between positive and negative affect and a range of 12-month physical disorders were investigated in the Midlife Development in the United States Survey, a nationally representative sample of 3,032 adults ages 25-74. These associations were examined, controlling for relevant sociodemographic and psychiatric covariates. High positive affect was associated with decreased risk of physical disorders, whereas high negative affect was associated with increased risk. However, associations between positive affect and physical disorders were partially attenuated following adjustment for concurrent negative affect. Additionally, high affect balance was associated with decreased risk of physical disorders before and after adjustments. These findings underscore the relevance of affective disposition in health status, suggesting that both positive and negative affect may serve as viable health risk parameters.

  16. Seasonal timing of first rain storms affects rare plant population dynamics

    2011-01-01

    A major challenge in forecasting the ecological consequences of climate change is understanding the relative importance of changes to mean conditions vs. changes to discrete climatic events, such as storms, frosts, or droughts. Here we show that the first major storm of the growing season strongly influences the population dynamics of three rare and endangered annual plant species in a coastal California (USA) ecosystem. In a field experiment we used moisture barriers and water addition to manipulate the timing and temperature associated with first major rains of the season. The three focal species showed two- to fivefold variation in per capita population growth rates between the different storm treatments, comparable to variation found in a prior experiment imposing eightfold differences in season-long precipitation. Variation in germination was a major demographic driver of how two of three species responded to the first rains. For one of these species, the timing of the storm was the most critical determinant of its germination, while the other showed enhanced germination with colder storm temperatures. The role of temperature was further supported by laboratory trials showing enhanced germination in cooler treatments. Our work suggests that, because of species-specific cues for demographic transitions such as germination, changes to discrete climate events may be as, if not more, important than changes to season-long variables.

    Despite advances in the treatment and prevention of influenza, it is still considered an important cause of morbidity and mortality worldwide. Annual vaccination is the safest and most effective mean of prevention. Our study aims were to explore the uptake of influenza vaccination among children with gastrointestinal disorders, and to characterize non-adherent patients. The present cross-sectional study included parents of pediatric patients attending the Gastroenterology Institute at Schneider Children's Medical Center of Israel between September and October 2011. Parents were asked to complete a questionnaire concerning demographic and clinical parameters, influenza vaccination of the child, and reasons for not vaccinating the child, when appropriate. The study population included 273 patients (50% female), with a median age of 10 years (range, 2-18 years). Overall, the rate of seasonal influenza vaccination was 30.8%. Higher rates were found among immunosuppressed patients (46.1%), and in patients with inflammatory bowel disease (50%). There was no significant effect of patient age, gender, ethnic origin or parental level of education on the vaccination rate. Vaccination rates were significantly associated with parents' information and knowledge of, as well as their personal beliefs regarding the vaccine (Pvaccination rates are relatively low in the pediatric population attending gastroenterology clinics, in both high- and low-risk groups. The importance of parental knowledge in compliance with influenza vaccination of children should prompt general pediatricians and gastroenterologists to discuss and address the common misconceptions regarding the vaccine.

    Various stressors trigger cardiac death. The objective was to investigate a possible relation between a stock market crash and cardiac death in a large population within the United States. We obtained daily stock market data (Dow Jones Industrial Average Index), death certificate data for daily deaths in Los Angeles County (LA), and annual LA population estimates for 2005 through 2008. The 4 years death rate curves (2005 through 2008) were averaged into a single curve to illustrate annual trends. Data were "deseasonalized" by subtracting from the daily observed value the average value for that day of year. There was marked seasonal variation in total and cardiac death rates. Even in the mild LA climate, death rates were higher in winter versus summer including total death (+17%), circulatory death (+24%), coronary heart disease death (+28%), and myocardial infarction death (+38%) rates (p stock market crash in October 2008 did not affect death rates in LA. Death rates remained at or below seasonal averages during the stock market crash. In conclusion, after correcting for seasonal variation, the stock market crash in October 2008 was not associated with an increase in total or cardiac death in LA. Annual coronary heart disease death rates continue to decrease. However, seasonal variation (specifically winter) remains a trigger for death and coronary heart disease death even in LA where winters are mild. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available Affect regulation is often compromised as a result of early life interpersonal traumatization and disruption in caregiving relationships like in situations where the caretaker is emotionally, sexually or physically abusing the child. Prior studies suggest a clear relationship between early childhood attachment-related psychological trauma and affect dysregulation. We evaluated the relationship of retrospectively recalled childhood traumatization by primary caretaker(s (TPC and affect dysregulation in 472 adult psychiatric patients diagnosed with borderline personality disorder (BPD, somatoform disorder (SoD, both BPD and SoD, or disorders other than BPD or SoD, using the Bermond-Vorst Alexithymia Questionnaire, the self-report version of the Structured Interview for Disorders of Extreme Stress, the Self-rating Inventory for Posttraumatic Stress Disorder (SRIP and the Traumatic Experiences Checklist. Almost two-thirds of participants reported having experienced childhood TPC, ranging from approximately 50% of patients with SoD or other psychiatric disorders to more than 75% of patients with comorbid BPD + SoD. Underregulation of affect was associated with emotional TPC and TPC occurring in developmental epoch 0–6 years. Over-regulation of affect was associated with physical TPC. Childhood trauma by a primary caretaker is prevalent among psychiatric patients, particularly those with BPD, and differentially associated with underand over-regulation of affect depending on the type of traumatic exposure.For the abstract or full text in other languages, please see Supplementary files under Reading Tools online

  5. Neural systems supporting cognitive-affective interactions in adolescence: The role of puberty and implications for affective disorders

    Directory of Open Access Journals (Sweden)

    Cecile D. Ladouceur

    2012-08-01

    Full Text Available Evidence from longitudinal studies suggests that adolescence may represent a period of vulnerability that, in the context of adverse events, could contribute to developmental trajectories toward behavioral and emotional health problems, including affective disorders. Adolescence is also a sensitive period for the development of neural systems supporting cognitive-affective processes, which have been implicated in the pathophysiology of affective disorders such as anxiety and mood disorders. In particular, the onset of puberty brings about a cascade of physical, hormonal, psychological, and social changes that contribute in complex ways to the development of these systems. This article provides a brief overview of neuroimaging research pertaining to the development of cognitive-affective processes in adolescence. It also includes a brief review of evidence from animal and human neuroimaging studies suggesting that sex steroids influence the connectivity between prefrontal cortical and subcortical limbic regions in ways that contribute to increased reactivity to emotionally salient stimuli. We integrate these findings in the context of a developmental affective neuroscience framework suggesting that the impact of rising levels of sex steroids during puberty on fronto-limbic connectivity may be even greater in the context of protracted development of prefrontal cortical regions in adolescence. We conclude by discussing the implications of these findings for future research aimed at identifying neurodevelopmental markers of risk for future onset of affective disorders.

    Evidence suggests that Repetitive Head Impacts (RHI) directly influence the brain over the course of a single contact collision season yet do not significantly impact a player's performance on the standard clinical concussion assessment battery. The purpose of this study was to investigate changes in static postural control after a season of RHI in Division I football athletes using more sensitive measures of postural control as compared to a non-head contact sports. Fourteen Division I football players (CON) (age=20.4±1.12years) and fourteen non-contact athletes (NON) (2 male, 11 female; age=19.85±1.21years) completed a single trial of two minutes of eyes open quiet upright stance on a force platform (1000Hz) prior to athletic participation (PRE) and at the end of the athletic season (POST). All CON athletes wore helmets outfitted with Head Impact Telemetry (HIT) sensors and total number of RHI and linear accelerations forces of each RHI were recorded. Center of pressure root mean square (RMS), peak excursion velocity (PEV), and sample entropy (SampEn) in the anteroposterior (AP) and mediolateral (ML) directions were calculated. CON group experienced 649.5±496.8 mean number of impacts, 27.1±3.0 mean linear accelerations, with ≈1% of total player impacts exceeded 98g over the course of the season. There were no significant interactions for group x time RMS in the AP (p=0.434) and ML (p=0.114) directions, PEV in the AP (p=0.262) and ML (p=0.977) directions, and SampEn in the AP (p=0.499) and ML (p=0.984) directions. In addition, no significant interactions for group were observed for RMS in the AP (p=0.105) and ML (p=0.272) directions, PEV in the AP (p=0.081) and ML (p=0.143) directions, and SampEn in the AP (p=0.583) and ML (p=0.129) directions. These results suggest that over the course of a single competitive season, RHI do not negatively impact postural control even when measured with sensitive non-linear metrics.

    Previous research on serum total cholesterol and suicidality has yielded conflicting results. Several studies have reported a link between low serum total cholesterol and suicidality, whereas others have failed to replicate these findings, particularly in patients with major affective disorders. These discordant findings may reflect the fact that studies often do not distinguish between patients with bipolar and unipolar depression; moreover, definitions and classification schemes for suicide attempts in the literature vary widely. Subjects were patients with one of the three major psychiatric disorders commonly associated with suicide: schizophrenia, bipolar affective disorder, and major depressive disorder (MDD). We compared serum lipid levels in patients who died by suicide (82 schizophrenia, 23 bipolar affective disorder, and 67 MDD) and non-suicide controls (200 schizophrenia, 49 bipolar affective disorder, and 175 MDD). Serum lipid profiles did not differ between patients who died by suicide and control patients in any diagnostic group. Our results do not support the use of biological indicators such as serum total cholesterol to predict suicide risk among patients with a major psychiatric disorder.

    Full Text Available In this review, we focus on CA3 neuronal migration disorders in the rodent. We begin by introducing the main steps of hippocampal development, and we summarize characteristic hippocampal malformations in human. We then describe various mouse mutants showing structural hippocampal defects. Notably, genes identified in human cortical neuronal migration disorders consistently give rise to a CA3 phenotype when mutated in the mouse. We successively describe their molecular, physiological and behavioral phenotypes that together contribute to a better understanding of CA3-dependent functions. We finally discuss potential factors underlying the CA3 vulnerability revealed by these mouse mutants and that may also contribute to other human neurological and psychiatric disorders.

    Fire is frequently used as a land management tool for cattle ranching and annual crops in the Amazon. However, these maintenance fires often escape into surrounding forests, with potentially severe impacts for forest biodiversity. We examined the effect of experimental fires on leaf-litter arthropod abundance in a seasonally-dry forest in the Brazilian Amazon. The study plots (50 ha each) included a thrice-burned forest and an unburned control forest. Pitfall-trap samples were collected at 160 randomly selected points in both plots, with sampling stratified across four intra-annual replicates across the dry and wet seasons, corresponding to 6, 8, 10 and 12 months after the most recent fire. Arthropods were identified to the level of order (separating Formicidae). In order to better understand the processes that determine arthropod abundance in thrice-burned forests, we measured canopy openness, understory density and litter depth. All arthropod taxa were significantly affected by fire and season. In addition, the interactions between burn treatment and season were highly significant for all taxa but Isoptera. The burned plot was characterized by a more open canopy, lower understory density and shallower litter depth. Hierarchical partitioning revealed that canopy openness was the most important factor explaining arthropod order abundances in the thrice-burned plot, whereas all three environmental variables were significant in the unburned control plot. These results reveal the marked impact of recurrent wildfires and seasonality on litter arthropods in this transitional forest, and demonstrate the overwhelming importance of canopy-openness in driving post-fire arthropod abundance.

    Full Text Available Soil profiles were collected in three salt marshes with different plant species (i.e. Phragmites australis, Tamarix chinensis and Suaeda salsa in the Yellow River Delta (YRD of China during three seasons (summer and fall of 2007 and the following spring of 2008 after the flow-sediment regulation regime. Total elemental contents of As, Cd, Cu, Pb and Zn were determined using inductively coupled plasma atomic absorption spectrometry to investigate temporal variations in trace elements in soil profiles of the three salt marshes, assess the enrichment levels and ecological risks of these trace elements in three sampling seasons and identify their influencing factors. Trace elements did not change significantly along soil profiles at each site in each sampling season. The highest value for each sampling site was observed in summer and the lowest one in fall. Soils in both P. australis and S. salsa wetlands tended to have higher trace element levels than those in T. chinensis wetland. Compared to other elements, both Cd and As had higher enrichment factors exceeding moderate enrichment levels. However, the toxic unit (TU values of these trace elements did not exceed probable effect levels. Correlation analysis showed that these trace elements were closely linked to soil properties such as moisture, sulfur, salinity, soil organic matter, soil texture and pH values. Principal component analysis showed that the sampling season affected by the flow-sediment regulation regime was the dominant factor influencing the distribution patterns of these trace elements in soils, and plant community type was another important factor. The findings of this study could contribute to wetland conservation and management in coastal regions affected by the hydrological engineering.

  12. Habitat degradation and seasonality affect physiological stress levels of Eulemur collaris in littoral forest fragments.

    Full Text Available The littoral forest on sandy soil is among the most threatened habitats in Madagascar and, as such, it represents a hot-spot within a conservation hot-spot. Assessing the health of the resident lemur fauna is not only critical for the long-term viability of these populations, but also necessary for the future re-habilitation of this unique habitat. Since the Endangered collared brown lemur, Eulemur collaris, is the largest seed disperser of the Malagasy south-eastern littoral forest its survival in this habitat is crucial. In this study we compared fecal glucocorticoid metabolite (fGCM levels, a measure of physiological stress and potential early indicator of population health, between groups of collared brown lemurs living in a degraded forest fragment and groups occurring in a more preserved area. For this, we analysed 279 fecal samples collected year-round from 4 groups of collared brown lemurs using a validated 11-oxoetiocholanolone enzyme immunoassay and tested if fGCM levels were influenced by reproductive stages, phenological seasons, sex, and habitat degradation. The lemurs living in the degraded forest had significantly higher fGCM levels than those living in the more preserved area. In particular, the highest fGCM levels were found during the mating season in all animals and in females during gestation in the degraded forest. Since mating and gestation are both occurring during the lean season in the littoral forest, these results likely reflect a combination of ecological and reproductive pressures. Our findings provide a clear indication that habitat degradation has additive effects to the challenges found in the natural habitat. Since increased stress hormone output may have long-term negative effects on population health and reproduction, our data emphasize the need for and may add to the development of effective conservation plans for the species.

  13. Environmental Factors and Seasonality Affect the Concentration of Rotundone in Vitis vinifera L. cv. Shiraz Wine.

    Full Text Available Rotundone is a sesquiterpene that gives grapes and wine a desirable 'peppery' aroma. Previous research has reported that growing grapevines in a cool climate is an important factor that drives rotundone accumulation in grape berries and wine. This study used historical data sets to investigate which weather parameters are mostly influencing rotundone concentration in grape berries and wine. For this purpose, wines produced from 15 vintages from the same Shiraz vineyard (The Old Block, Mount Langi Ghiran, Victoria, Australia were analysed for rotundone concentration and compared to comprehensive weather data and minimal temperature information. Degree hours were obtained by interpolating available temperature information from the vineyard site using a simple piecewise cubic hermite interpolating polynomial method (PCHIP. Results showed that the highest concentrations of rotundone were consistently found in wines from cool and wet seasons. The Principal Component Analysis (PCA showed that the concentration of rotundone in wine was negatively correlated with daily solar exposure and grape bunch zone temperature, and positively correlated with vineyard water balance. Finally, models were constructed based on the Gompertz function to describe the dynamics of rotundone concentration in berries through the ripening process according to phenological and thermal times. This characterisation is an important step forward to potentially predict the final quality of the resultant wines based on the evolution of specific compounds in berries according to critical environmental and micrometeorological variables. The modelling techniques described in this paper were able to describe the behaviour of rotundone concentration based on seasonal weather conditions and grapevine phenological stages, and could be potentially used to predict the final rotundone concentration early in future growing seasons. This could enable the adoption of precision irrigation and

    Instability of affects and interpersonal relations are important features of borderline personality disorder (BPD). Interpersonal problems of individuals suffering from BPD might develop based on abnormalities in the processing of facial affects and high sensitivity to negative affective expressions. The aims of the present study were to examine automatic evaluative shifts and latencies as a function of masked facial affects in patients with BPD compared to healthy individuals. As BPD comorbidity rates for mental and personality disorders are high, we investigated also the relationships of affective processing characteristics with specific borderline symptoms and comorbidity. Twenty-nine women with BPD and 38 healthy women participated in the study. The majority of patients suffered from additional Axis I disorders and/or additional personality disorders. In the priming experiment, angry, happy, neutral, or no facial expression was briefly presented (for 33 ms) and masked by neutral faces that had to be evaluated. Evaluative decisions and response latencies were registered. Borderline-typical symptomatology was assessed with the Borderline Symptom List. In the total sample, valence-congruent evaluative shifts and delays of evaluative decision due to facial affect were observed. No between-group differences were obtained for evaluative decisions and latencies. The presence of comorbid anxiety disorders was found to be positively correlated with evaluative shifting owing to masked happy primes, regardless of baseline-neutral or no facial expression condition. The presence of comorbid depressive disorder, paranoid personality disorder, and symptoms of social isolation and self-aggression were significantly correlated with response delay due to masked angry faces, regardless of baseline. In the present affective priming study, no abnormalities in the automatic recognition and processing of facial affects were observed in BPD patients compared to healthy individuals

    Full Text Available Background: Marital adjustment is considered as a part of social well-being. Disturbed marital relationship can directly affect the disease adjustment and the way they face disease outcomes and complications. It may adversely affect physical health, mental health, the quality-of-life and even economic status of individuals. Aim: The aim of this study was to compare the marital adjustment among patients with substance dependence, schizophrenia and bipolar affective disorder. Materials and Methods: The sample consisted of each 30 patients with substance dependence, bipolar affective disorder and schizophrenia, diagnosed as per international classification of diseases-10 diagnostic criteria for research with a minimum duration of illness of 1 year were evaluated using marital adjustment questionnaire. The data was analyzed using parametric and non-parametric statistics. Results: Prevalence of poor marital adjustment in patients with schizophrenia, bipolar affective disorder and substance dependence was 60%, 70% and 50% respectively. There was a significant difference on overall marital adjustment among substance dependence and bipolar affective disorder patients. There was no significant difference on overall marital adjustment among patients with substance dependence and schizophrenia as well as among patients with schizophrenia and bipolar affective disorder. On marital adjustment domains, schizophrenia patients had significantly poor sexual adjustment than substance dependence patients while bipolar affective disorder patients had significantly poor sexual and social adjustment compared with substance dependence patients. Conclusion: Patients with substance dependence have significant better overall marital adjustment compared with bipolar affective disorder patients. Patients with substance dependence have significantly better social and sexual adjustment than patients with bipolar affective disorder as well as significantly better sexual

  4. Narcissistic disorder and the failure of symbolisation: a Relational Affective Hypothesis.

    2014-09-01

    The psychoanalytic concept of narcissistic disorder is broader than that of Narcissistic Personality Disorder (DSM-5 [1]), underlying a range of Personality Disorders (PD) and their co-morbidities. Existing Mentalisation, Psychoanalytic and Cognitive models, fail to account fully for the emerging evidence of biological, developmental, relational and defensive contributions to narcissistic disorder, nor do they account for the common and variant features of co-morbidities namely Anorexia Nervosa, Somatisation, Substance Misuse and Autistic Spectrum Disorder. Alexithymia and concrete modes of relating are common findings in narcissistic disorder and these co-morbid conditions. Current models do not provide a comprehensive account, on the basis of neuro-scientific and developmental evidence, of how affective feelings come to be represented in words and the association between narcissistic disorders and failures of symbolisation. In this paper I propose an empirically based Relational Affective Hypothesis that narcissistic disorder and its comorbidities represent failures at specific points on a representational function pathway through which subcortical affect and visceral feeling in a relational context become the basis for abstraction and language. The elucidation of this pathway allows investigation of the contribution of biological, social and psychogenic factors in narcissistic disorders. It also brings a new understanding of the neurological underpinning of psychodynamic defences in narcissistic disorders. Research and novel treatment implications are briefly considered.

    The primary aim of the current study was to test the hypothesis that there is a seasonal component to snoring and obstructive sleep apnea (OSA) through the use of Google search engine query data. Internet search engine query data were retrieved from Google Trends from January 2006 to December 2012. Monthly normalized search volume was obtained over that 7-year period in the USA and Australia for the following search terms: "snoring" and "sleep apnea". Seasonal effects were investigated by fitting cosinor regression models. In addition, the search terms "snoring children" and "sleep apnea children" were evaluated to examine seasonal effects in pediatric populations. Statistically significant seasonal effects were found using cosinor analysis in both USA and Australia for "snoring" (p search term in Australia (p = 0.13). Seasonal patterns for "snoring children" and "sleep apnea children" were observed in the USA (p = 0.002 and p search volume to examine these search terms in Australia. All searches peaked in the winter or early spring in both countries, with the magnitude of seasonal effect ranging from 5 to 50 %. Our findings indicate that there are significant seasonal trends for both snoring and sleep apnea internet search engine queries, with a peak in the winter and early spring. Further research is indicated to determine the mechanisms underlying these findings, whether they have clinical impact, and if they are associated with other comorbid medical conditions that have similar patterns of seasonal exacerbation.

  6. Affective spectrum disorders and role of serotonergic system of the brain

    Directory of Open Access Journals (Sweden)

    Timotijević Ivana P.

    2014-01-01

    Full Text Available Affective spectrum disorders include mood and anxiety disorders, whereas the term functional somatic syndromes describes disorders in which the main symptom is chronic pain, with no pathognomonic tissue damage, such as fibromyalgia, irritable colon, tension headache. Pain as a symptom is often present in patients with depression and anxiety, and similarly, depressed mood, anxiety and other psychiatric symptoms are common in patients with functional somatic syndromes. This explains attitudes that affective disorders and functional somatic syndromes should be found along the same spectrum, due to a similar neurobiochemicalmehanism and dysfunction of these CNS structures and neurotransmitter systems, which lead to similar symptoms in both groups. The symptoms of affective disorders, including somatic are associated with serotonin and serotonergic transmission in the CNS. The existence of depressive and anxiety disorders, such as fatigue, sleep disorders, cognitive disorders, depressed mood, anxiety, and functional somatic syndromes code indicate a similar mechanism of origin. Hypothesis of central neuropathic pain explains the possibility of the descending inhibitory pain mechanisms, including serotonergic and noradrenergic projections and their receptors. Central suprasegmental senzitization in nociceptive pathways, also at the level of the thalamus and the sensory cortex, trigered by an emotional stressors can cause painful symptoms in both groups of disorders. Serotonergic and noradrenergic pathways and voltage sensitive channels of their receptors are included in the mechanism. Modern psychopharmacology can no longer ignore the existence of painful symptoms in affective disorder or depressive and anxiety symptoms in functional somatic syndromes and their treatment can improve. Therapeutic effects of SSRI and SNRI antidepressants and alpha 2 delta ligands for all kinds of painful symptoms in affective disorders - serotonergic spectrum is

    This supplement describes the development and structure of the Comprehensive Assessment List of Affective Disorders (COALA) system, which was recently developed for a collaborative follow-up study of a broad spectrum of affective disorders in Japan and which consists of a series of semistructured interviews for affective and related disorders. The COALA distinguishes itself from the extant semistructured interviews by being able to provide polydiagnostic, comprehensive and serial assessments. It is polydiagnostic because it derives diagnoses according to 29 historical and modern diagnostic systems through computer algorithms. It is comprehensive because it not only depicts the symptoms profile and rates their severity according to various endogenicity indices and severity rating scales but also measures, in the psychosocial domain, the life events and their characteristics. In addition, it has sections for past illnesses and family history. It is serial because the system includes follow-up semistructured interviews that can be administered monthly and that monitor changes in the psychopathological and psychosocial features. The theoretical underpinnings of the COALA system, especially its polydiagnostic approach to a broad spectrum of affective disorders and its treatment of psychosocial factors, are discussed in view of recent proposals for the future nosological research. The findings of the interrater reliability study (n = 107) are also presented, with satisfactory to excellent results for almost all of the psychopathological and psychosocial variables, all of the composite severity ratings and most of the polydiagnostic evaluations.

    Suicide and mood disorders (especially major depressive disorder (MDD) and bipolar affective disorder (BD)) represent a significant global health burden. Major depressive disorder and bipolar affective disorder have been associated with increased risk for suicide. Some specific suicide risk factors might be found in underlying individual personality traits. Specific personality features may predispose an individual to mood disorders (MDD or BD) hence increased suicide risk. The specificity of this research is in the assessment of personality features during the acute phase of illness immediately after suicide attempt which resulted in psychiatric inpatient treatment. The study included 119 unrelated Caucasian participants with MDD-severe depressive episode without psychotic symptoms (MDD) and BD-severe depressive episode without psychotic symptoms (BD-sDE). Both groups of patients with MDD and BD-sDE were divided into the suicide attempters and non-suicidal group. The diagnoses of the severe depressive episode without psychotic symptoms in major depressive disorder (MDD; F32.2) and bipolar disorder (BD-sDE; F31.4) were made according to ICD-10 (WHO 1992) diagnostic criteria. Methods of suicide attempts were also assessed according to ICD-10 and a self-report questionnaire, the Temperament and Character Inventory (TCI) was applied. The participants who exhibited suicide attempt had significantly higher scores on harm-avoidance (HA) (psuicidal attempt had significantly lower scores on self-directedness (SD) (psuicide attempt may have some significantly different personality traits than non-suicidal patients with mood disorders. The combination of high harm-avoidance (HA) and low self-directedness (SD) may be specific for depressive episode while the combination of high HA, novelty-seeking (NS), and self-transcendence (ST) with low SD may be related to suicide attempts during the depressive episode in bipolar disorder.

    Clinical psychiatry has focused almost entirely on the psychopathology of the affective disorders. The authors studied responses of 61 patients (35 bipolar. 26 unipolar) to questions about perceived short- and long-term benefits (increased sensitivity, sexuality, productivity, creativity, and social outgoingness) they attributed to their affective illness. Bipolar patients strongly indicated positive experiences associated with manic-depressive illness; few unipolar patients perceived their disorder in such a way. Significant sex differences emerged in the attributions made by bipolar patients.

    Investigating the potential effects of handling and marking techniques on study animals is important for correct interpretation of research results and to effect progress in data-collection methods. Few investigators have compared the reproductive output of radio-tagged and non-radio-tagged songbirds, and no one to date has examined the possible effect of radio-tagging adult songbirds on the survival of their fledglings. In 2011 and 2012, we compared several parameters of reproductive output of two groups of female Golden-winged Warblers (Vermivora chrysoptera) breeding in Minnesota, including 45 females with radio-transmitters and 73 females we did not capture, handle, or mark. We found no difference between groups in clutch sizes, hatching success, brood sizes, length of incubation and nestling stages, fledging success, number of fledglings, or survival of fledglings to independence. Thus, radio-tags had no measurable impact on the productivity of female Golden-winged Warblers. Our results build upon previous studies where investigators have reported no effects of radio-tagging on the breeding parameters of songbirds by also demonstrating no effect of radio-tagging through the post-fledging period and, therefore, the entire breeding season.

    Although intranasal corticosteroids (INSs) are the first-line treatment for seasonal allergic rhinitis (SAR), some patients do not respond adequately, reflecting biological heterogeneity or confounding conditions. The objective of this study was to determine what recruitment factors identify SAR subjects who will be unresponsive to mometasone furoate (MF). We performed a 2-week, double-blind, placebo-controlled, parallel study on 40 subjects with SAR. Each subject underwent a decongestant test using oxymetazoline. Baseline nasal symptoms, nasal peak inspiratory flow (NPIF) and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores were recorded. Next, subjects were randomized to either 200 μg of MF or placebo. Symptom diaries and NPIF measurements were completed twice daily. After 2 weeks, subjects repeated the RQLQ and the global assessment of symptoms. There was a significant reduction in symptoms in the MF group compared with placebo (p ≤ 0.05) in patients with baseline total symptom scores of ≥6. Multivariate analysis showed that treatment (MF versus placebo; p = 0.049) and amount of decongestion (percent change in NPIF after oxymetazoline; p = 0.008) predicted the improvement in total nasal symptoms. In clinical trials, SAR subjects must report multiple symptoms to be responsive to treatment with INSs. Our results also support the use of the decongestant test for choice of appropriate study volunteers, both to ensure participation of potentially responsive subjects and to eliminate those with confounding issues.

    This study aimed to determine the prevalence of addiction to social networking sites/platforms (SNS) and its comorbidity with other behavioral addiction and affective disorder among college students in Singapore. 1110 college students (age: M=21.46, SD=1.80) in Singapore completed measures assessing online social networking, unhealthy food intake and shopping addiction as well as depression, anxiety and mania. Descriptive analyses were conducted to investigate the prevalence and comorbidity of behavioral addiction and affective disorder. Chi-square tests were used to examine gender differences. The prevalence rates of SNS, food and shopping addiction were 29.5%, 4.7% and 9.3% respectively for the total sample. SNS addiction was found to co-occur with food addiction (3%), shopping addiction (5%), and both food and shopping addiction (1%). The comorbidity rates of SNS addiction and affective disorder were 21% for depression, 27.7% for anxiety, and 26.1% for mania. Compared with the total sample, students with SNS addiction reported higher comorbidity rates with other behavioral addiction and affective disorder. In general, females as compared to males reported higher comorbidity rates of SNS addiction and affective disorder. SNS addiction has a high prevalence rate among college students in Singapore. Students with SNS addiction were vulnerable to experience other behavior addiction as well as affective disorder, especially among females. Copyright © 2016. Published by Elsevier B.V.

    Honey bees (Apis mellifera L.) show a large variation in foraging distances and use a broad range of plant species as pollen resources, even in regions with intensive agriculture. However, it is unknown how increasing areas of mass-flowering crops like oilseed rape (Brassica napus; OSR) or a decrease of seminatural habitats (SNH) change the temporal and spatial availability of pollen resources for honey bee colonies, and thus foraging distances and frequency in different habitat types. We studied pollen foraging of honey bee colonies in 16 agricultural landscapes with independent gradients of OSR and SNH area within 2 km and used waggle dances and digital geographic maps with major land cover types to reveal the distance and visited habitat type on a landscape level. Mean pollen foraging distance of 1347 decoded bee dances was 1015 m (± 26 m; SEM). In spring, increasing area of flowering OSR within 2 km reduced mean pollen foraging distances from 1324 m to only 435 m. In summer, increasing cover of SNH areas close to the colonies (within 200 m radius) reduced mean pollen foraging distances from 846 to 469 m. Frequency of pollen foragers per habitat type, measured as the number of dances per hour and hectare, was equally high for SNH, grassland, and OSR fields, but lower for other crops and forests. In landscapes with a small proportion of SNH a significantly higher density of pollen foragers on SNH was observed, indicating that pollen resources in such simple agricultural landscapes are more limited. Overall, we conclude that SNH and mass-flowering crops can reduce foraging distances of honey bee colonies at different scales and seasons with possible benefits for the performance of honey bee colonies. Further, mixed agricultural landscapes with a high proportion of SNH reduce foraging densities of honey bees in SNH and thus possible competition for pollen resources. © 2016 by the Ecological Society of America.

    Changes in river water quality were investigated along the lower reach of the Thur River, Switzerland, following river restoration and a summer storm event. River restoration and hydrological storm events can each cause dramatic changes to water quality by affecting various bio-geochemical processes in the river, but have to date not been well documented, especially in combination. Evaluating the success of river restoration is often restricted in large catchments due to a lack of high frequency water quality data, which are needed for process understanding. These challenges were addressed in this study by measuring water quality parameters including dissolved oxygen (DO), temperature, pH, electrical conductivity (EC), nitrate and dissolved organic carbon (DOC) with a high temporal frequency (15 min–1 h) over selected time scales. In addition, the stable isotopes of water (δD and δ{sup 18}O-H{sub 2}O) as well as those of nitrate (δ{sup 15}N-NO{sub 3}{sup −} and δ{sup 18}O-NO{sub 3}{sup −}) were measured to follow changes in water quality in response to the hydrological changes in the river. To compare the spatial distribution of pre- and post-restoration water quality, the sampling stations were chosen upstream and downstream of the restored section. The diurnal and seasonal changes were monitored by conducting 24-hour campaigns in three seasons (winter, summer and autumn) in 2012 and 2013. The amplitude of the diurnal changes of the various observed parameters showed significant seasonal and spatial variability. Biological processes — mainly photosynthesis and respiration — were found to be the major drivers of these diurnal cycles. During low flow in autumn, a reduction of nitrate (attributed to assimilation by autotrophs) in the pre-dawn period and a production of DOC during the daytime (attributed to photosynthesis) were observed downstream of the restored site. Further, a summer storm event was found to override the influence of these biological

    This paper aims to describe the prevalence, assessment and management of affective disorders as well as functional (non-epileptic) seizures in people with epilepsy. This paper comprises a selective review of the literature of the common affective manifestations of epilepsy. Affective disorders are the most common psychiatric comorbidity seen in people with epilepsy and assessment and management parallels that of the general population. Additionally, people with epilepsy may experience higher rates of mood instability, irritability and euphoria, classified together as a group, interictal dysphoric disorder and resembling an unstable bipolar Type II disorder. Functional seizures present unique challenges in terms of identification of the disorder and a lack of specific management. Given their high prevalence, it is important to be able to recognise affective disorders in people with epilepsy. Management principles parallel those in the general population with specific caution exercised regarding the potential interactions between antidepressant medications and antiepileptic drugs. Functional seizures are more complex and require a coordinated approach involving neurologists, psychiatrists, general practitioners, nursing and allied health. There is very limited evidence to guide psychological and behavioural interventions for neurotic disorders in epilepsy and much more research is needed. © The Royal Australian and New Zealand College of Psychiatrists 2016.

    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

    We used the technique of autoradiography after incorporation of tritiated thymidine ( 3 H-TdR) to evaluate keratinocyte proliferation in basal, epibasal, and other epidermal layers in 30 diseases affecting the epidermis. The number and proportion of 3 H-TdR-labeled keratinocytes were counted in the different layers of the epidermis. Significant correlations were found between the proliferative indices of the different epidermal layers. Such links indicate that the epidermis responds in a rather stereotyped way to various pathological conditions. There exists some regulation in the distribution, number, and proportion of 3 H-TdR-labeled keratinocytes in the various layers of the epidermis

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

    Successful recruitment is vital for any research study. Difficulties in recruitment are not uncommon and can have important implications. This is particularly relevant to research conducted in affective disorders due to the nature of the conditions and the clinical services that serve these patients. Recently, online public advertisements have become more generally accessible and may provide an effective way to recruit patient populations. However, there is paucity of evidence on their viability as a method of recruiting patients into studies of disease mechanisms in these disorders. Public advertisement methods can be useful when researchers require specific populations, such as those not receiving pharmacological treatment. This work describes our experience in successfully recruiting participants into neuroimaging research studies in affective disorders using online public advertisements. Results suggest that these online public advertisements are an effective method for successfully recruiting participants with affective disorders into research studies, particularly for research focusing on disease mechanisms in specific populations.

    The objectives of the study were (1) to determine the prevalence and characteristics of pseudobulbar affect (PBA) in patients with primary lateral sclerosis (PLS) and amyotrophic lateral sclerosis (ALS) in an outpatient clinic population, and (2) to test the hypothesis that damage of inputs to the cerebellum, leading to cerebellar dysmodulation, is associated with PBA. Chart review of all patients with PLS and ALS seen between 2000 and 2013. The examining neurologist documented the presence or absence of PBA in 87 patients. Forty-seven patients also had diffusion tensor imaging (DTI) studies. Tract-based spatial statistics were used to compare DTI of patients with and without PBA to identify altered white matter tracts associated with PBA. Thirty-one of 50 patients with PLS and 12 of 37 patients with ALS had PBA. Psychiatric/emotional assessment found congruence between mood and affect during episodes, but excessive magnitude of the response. DTI studies of 25 PLS and 22 ALS patient brains showed reduced fractional anisotropy of the corticospinal and callosal white matter tracts in all patients. Patients with PBA additionally had increased mean diffusivity of white matter tracts underlying the frontotemporal cortex, the transverse pontine fibers, and the middle cerebellar peduncle. PBA is common in PLS. Imaging findings showing disruption of corticopontocerebellar pathways support the hypothesis that PBA can be viewed as a "dysmetria" of emotional expression resulting from cerebellar dysmodulation. © 2014 American Academy of Neurology.

    Considerable attention has focused on the growing need for evidence-based psychotherapy for veterans with affective disorders within the Department of Veteran Affairs. Despite, and possibly due to, the large number of evidence-based protocols available, several obstacles remain in their widespread delivery within Veterans Affairs Medical Centers. In part as an effort to address these concerns, newer transdiagnostic approaches to psychotherapy have been developed to provide a single treatment that is capable of addressing several, related disorders. The goal of the present investigation was to develop and evaluate a transdiagnostic psychotherapy, Transdiagnostic Behavior Therapy (TBT), in veterans with affective disorders. Study 1 provided initial support for transdiagnostic presentation of evidence-based psychotherapy components in veterans with principal diagnoses of affective disorders (n=15). These findings were used to inform the development of the TBT protocol. In Study 2, an initial evaluation of TBT was completed in a second sample of veterans with principal diagnoses of affective disorders (n=29). The findings of Study 2 demonstrated significant improvements in symptoms of depression, anxiety, stress, posttraumatic stress, and related impairment across participants with various principal diagnoses. Together, the investigation provided preliminary support for effectiveness of TBT in veterans with affective disorders. Published by Elsevier Ireland Ltd.

    Full Text Available Abstract Background Variation in the COMT gene has been implicated in a number of psychiatric disorders, including psychotic, affective and anxiety disorders. The majority of these studies have focused on the functional Val108/158Met polymorphism and yielded conflicting results, with limited studies examining the relationship between other polymorphisms, or haplotypes, and psychiatric illness. We hypothesized that COMT variation may confer a general risk for psychiatric disorders and have genotyped four COMT variants (Val158Met, rs737865, rs165599, and a SNP in the P2 promoter [-278A/G; rs2097603] in 394 Caucasian cases and 467 controls. Cases included patients with schizophrenia (n = 196, schizoaffective disorder (n = 62, bipolar disorder (n = 82, major depression (n = 30, and patients diagnosed with either psychotic disorder NOS or depressive disorder NOS (n = 24. Results SNP rs2097603, the Val/Met variant and SNP rs165599 were significantly associated (p = 0.004; p = 0.05; p = 0.035 with a broad "all affected" diagnosis. Haplotype analysis revealed a potentially protective G-A-A-A haplotype haplotype (-278A/G; rs737865; Val108/158Met; rs165599, which was significantly underrepresented in this group (p = 0.0033 and contained the opposite alleles of the risk haplotype previously described by Shifman et al. Analysis of diagnostic subgroups within the "all affecteds group" showed an association of COMT in patients with psychotic disorders as well as in cases with affective illness although the associated variants differed. The protective haplotype remained significantly underrepresented in most of these subgroups. Conclusion Our results support the view that COMT variation provides a weak general predisposition to neuropsychiatric disease including psychotic and affective disorders.

    Player unavailability negatively affects team performance in elite football. However, whether player unavailability and its concomitant performance decrement is mediated by any changes in teams' match physical outputs is unknown. We examined whether the number of players injured (i.e. unavailable for match selection) was associated with any changes in teams' physical outputs. Prospective cohort study. Between-team variation was calculated by correlating average team availability with average physical outputs. Within-team variation was quantified using linear mixed modelling, using physical outputs - total distance, sprint count (efforts over 20km/h), and percent of distance covered at high speeds (>14km/h) - as outcome variables, and player unavailability as the independent variable of interest. To control for other factors that may influence match physical outputs, stage (group stage/knockout), venue (home/away), score differential, ball possession (%), team ranking (UEFA Club Coefficient), and average team age were all included as covariates. Teams' average player unavailability was positively associated with the average number of sprints they performed in matches across two seasons. Multilevel models similarly demonstrated that having 4 unavailable players was associated with 20.8 more sprints during matches in 2015/2016, and with an estimated 0.60-0.77% increase in the proportion of total distance run above 14km/h in both seasons. Player unavailability had a possibly positive and likely positive association with total match distances in the two respective seasons. Having more players injured and unavailable for match selection was associated with an increase in teams' match physical outputs. Copyright © 2017 Sports Medicine Australia.

    Full Text Available BACKGROUND: Bipolar disorder (BD is a significant cause of functional, cognitive, and social impairment. However, classic studies of functioning and social skills have not investigated how BD may impact behavior on the Internet. Given that the digital age has been changing the way people communicate, this study aims to investigate the pattern of Internet use in patients with BD. METHODS: This cross-sectional study assessed 30 patients with BD I or II and 30 matched controls. Patients were not in an acute mood episode, according to DSM-IV. A standard protocol examined sociodemographic variables and social behavior on the Internet, assessed by Facebook number of friends (FBN and lifetime estimated number of offline contacts (social network number, SNN. RESULTS: SNN (p<0.001 and FBN (p = 0.036 of patients with BD were significantly lower than those of controls. Also, variables related with Internet use were significantly lower in patients, e.g., close contacts on Facebook (p = 0.021, Internet experience (p = 0.020, and knowledge of terms associated with social networking sites (p = 0.042. Also, patients showed lower rates of the expected pattern of Internet use (based on their age generation, including a poorer knowledge of SNS (p = 0.018 and a lower frequency of Internet use (p = 0.010. DISCUSSION: This study suggests that patients with BD show smaller social networks both in real-world settings and on the Internet. Also, patients tend to use the Internet and social networking sites less frequently and show a poorer knowledge of Internet and social media than healthy controls, below the expected for their generation. These significant differences between patients and controls suggest that the effects of BD on social relationships and functioning extend to electronic media.

    Extant research on emotional lability in borderline personality disorder (BPD) has focused almost exclusively on lability of individual emotions or emotion types, with limited research considering how different types of emotions shift together over time. Thus, this study examined the temporal dynamics of emotion in BPD at the level of both individual emotions (i.e., self-conscious emotions [SCE], anger, and anxiety) and mixed emotions (i.e., synchrony between emotions). One hundred forty-four women from the community completed a diagnostic interview and laboratory study involving 5 emotion induction tasks (each of which was preceded and followed by a 5-min resting period or neutral task). State ratings of SCE, anger, and anxiety were provided at 14 time points (before and after each laboratory task and resting period). Hierarchical linear modeling results indicate that women with BPD reported greater mean levels of SCE and Anxiety (but not Anger), and greater lability of Anxiety. Women with BPD also exhibited greater variability in lability of all 3 emotions (suggestive of within-group differences in the relevance of lability to BPD). Results also revealed synchrony (i.e., positive relations) between each possible pair of emotions, regardless of BPD status. Follow-up regression analyses suggest the importance of accounting for lability when examining the role of synchrony in BPD, as the relation of SCE-Anger synchrony to BPD symptom severity was moderated by Anger and SCE lability. Specifically, synchronous changes in SCE and Anger were associated with greater BPD symptom severity when large shifts in SCE were paired with minor shifts in Anger.

    So far there is a scarce of studies dealing with the relationship between different aspects of aggressive behaviour and affective temperaments among various mood disorders. The aim of the present study was to explore in a group of patients with affective mood disorders the relationship between affective temperaments and aggression. 100 consecutive outpatients in euthymic phase of mood disorders (46 with bipolar disorder-type I, 18 with bipolar disorder-type II and 36 with major depressive disorder) were self-assessed with the Aggression Questionnaire and the short version of Slovenian Temperament Evaluation of Memphis, Pisa, Paris and San Diego - Autoquestionnaire (TEMPS-A). The factorial analysis of the TEMPS-A subscales revealed 2 main factors: Factor 1 (prominent cyclothymic profile) consisted of cyclothymic, depressive, irritable, and anxious temperaments and Factor 2 (prominent hyperthymic profile) which was represented by the hyperthymic temperament, and by depressive and anxious temperaments as negative components. Patients with prominent cyclothymic profile got their diagnosis later in their life and had significantly higher mean scores on anger and hostility (non-motor aggressive behaviour) compared with patients with prominent hyperthymic profile. We included patients with different mood disorders, therefore the sample selection may influence temperamental and aggression profiles. We used self-report questionnaires which can elicit sociable desirable answers. Anger and hostility could represent stable personality characteristics of prominent cyclothymic profile that endure even in remission. It seems that distinct temperamental profile could serve as a good diagnostic and prognostic value for non-motor aspects of aggressive behaviour. Copyright © 2014 Elsevier B.V. All rights reserved.

    Negative affect intensity and hostility have both been implicated in alcohol use disorders (AUD) and post-traumatic stress disorder (PTSD) when they occur separately, but have neither been compared nor explored among those with dual diagnosis AUD and PTSD. This study is a secondary analysis designed to compare levels of negative affect intensity and hostility among those with AUD to those with dual diagnosis AUD and PTSD. Participants (n = 113) were recruited from the placebo-controlled groups of two distinct 12-week clinical trials (NCT00342563 and NCT00744055). The Short Affect Intensity Scale and Buss-Durkee Hostility Inventory were administered at weeks 0, 4, 8 and 12 to all study participants to assess negative affect intensity and hostility levels, respectively. Dual diagnosis AUD and PTSD individuals showed significantly higher levels of negative affect intensity and hostility than individuals with single diagnosis AUD. These levels remained relatively stable over the course of the study in spite of all study participants showing clinically significant improvements in AUD severity and PTSD symptomology (for those with dual diagnosis). Our results indicate that individuals with dual diagnosis AUD and PTSD have higher levels of negative affect and higher levels of hostility compared to individuals with single diagnosis AUD. In addition, these heightened levels of negative affect intensity and hostility appear to function somewhat independently of diagnosis severity and symptomology improvement. To our knowledge, this is the first study to compare negative affect intensity and hostility levels between single diagnosis AUD and dual diagnosis AUD and PTSD individuals.

    Affective instability is a core feature of borderline personality disorder (BPD). The use of advanced assessment methodologies and appropriate statistical analyses has led to consistent findings that indicate a heightened instability in patients with BPD compared with healthy controls. However, few studies have investigated the specificity of affective instability among patients with BPD with regard to relevant clinical control groups. In this study, 43 patients with BPD, 28 patients with posttraumatic stress disorder (PTSD), 20 patients with bulimia nervosa (BN), and 28 healthy controls carried e-diaries for 24 hours and were prompted to rate their momentary affective states approximately every 15 minutes while awake. To quantify instability, we used 3 state-of-the-art indices: multilevel models for squared successive differences (SSDs), multilevel models for probability of acute changes (PACs), and aggregated point-by-point changes (APPCs). Patients with BPD displayed heightened affective instability for emotional valence and distress compared with healthy controls, regardless of the specific instability indices. These results directly replicate earlier studies. However, affective instability did not seem to be specific to patients with BPD. With regard to SSDs, PACs, and APPCs, patients with PTSD or BN showed a similar heightened instability of affect (emotional valence and distress) to that of patients with BPD. Our results give raise to the discussion if affective instability is a transdiagnostic or a disorder-specific mechanism. Current evidence cannot answer this question, but investigating psychopathological mechanisms in everyday life across disorders is a promising approach to enhance validity and specificity of mental health diagnoses.

    The purpose of this study was to examine a collection of negative affect symptoms in relation to stages of eating disorder recovery. Depressive symptoms, anxiety symptoms, loneliness, and perceived stress are known to be present in individuals with eating disorders; however, less is known about the presence of such constructs throughout the recovery process. Does this negative affect fog continue to linger in individuals who have recovered from an eating disorder? Female participants seen at some point for an eating disorder at a primary care clinic were categorized into one of three groups using a stringent definition of eating disorder recovery based on physical, behavioral, and psychological criteria: active eating disorder (n =53), partially recovered (n =15; psychological criteria not met), and fully recovered (n =20; all recovery criteria met). Additionally, data were obtained from 67 female controls who had no history of an eating disorder. Self-report data indicated that controls and women fully recovered from an eating disorder scored significantly lower than partially recovered and active eating disorder groups in perceived stress, depression, and anxiety. Controls and the fully recovered group were statistically indistinguishable from each other in these domains, as were the partially recovered and active eating disorder groups, suggesting an interesting divide depending on whether psychological criteria (e.g., normative levels of weight/shape concern) were met. In contrast, controls and fully recovered and partially recovered groups all reported feeling significantly less lonely relative to those with an active eating disorder suggesting that improved perceptions of interpersonal, social support may act as a stepping stone toward more comprehensive eating disorder recovery. Future research may want to longitudinally determine if an increase in actual or perceived social support facilitates the movement toward full recovery and whether this, in turn, has

    To assess the effectiveness of a psycho-educational programme for the primary prevention of somatoform disorders in healthy primary care patients. Randomized, controlled trial. Participants (N=104) were randomly assigned to: (1) a psycho-educational intervention, or (2) no intervention at all. The primary outcome measure was somatoform disorder psychiatric diagnosis at 5-year follow-up. Secondary outcome measures were hypochondriasis, locus of control and attribution of symptoms and psychological distress. At 3 and 6 months, and 5 years, the intervention group significantly decreased hypochondriasis and somatic attributions; and increased psychological and normalizing attributions and internal locus of control. Five years after baseline, the prevalence of somatoform disorders showed no differences between both groups. Nevertheless, overall psychiatric morbidity was less prevalent in the intervention group (odds ratio: 2.72; 95%CI:1.10-6.72). In addition, a decrease in depression and anxiety subscales and in overall General Health Questionnaire scoring (psomatization seems to be useful, not to decrease somatoform disorders, but to prevent anxiety and depressive disorders.

    Objective : Affective disorders are frequently encountered among elderly populations, and the use of information and communication technologies (ICT) could provide an added value for their recognition and assessment in addition to current clinical methods. The diversity and lack of consensus in the emerging field of ICTs is however a strong limitation for their global use in daily practice. The aim of the present article is to provide recommendations for the use of ICTs for the assessment and management of affective disorders among elderly populations with or without dementia. Methods : A Delphi panel was organized to gather recommendations from experts in the domain. A set of initial general questions for the use of ICT in affective disorders was used to guide the discussion of the expert panel and to analyze the Strengths, Weaknesses, Opportunities, and Threats (SWOT) of employing ICT in elderly populations with affective disorders. Based on the results collected from this first round, a web survey was sent to local general practitioners (GPs) and to all interns in psychiatry in France. Results : The results of the first round revealed that ICT may offer very useful tools for practitioners involved in the diagnosis and management of affective disorders. However, the results of the web survey showed the interest to explain better to current and upcoming practitioners the utility of ICT especially for people living with dementia.

    One hundred and ten consecutive new patients presenting with major affective disorders were divided into five categories according to pattern of presentation: recurrent manic disorder, recurrent depressive disorder, bipolar disorder, single episodes of manic disorder, and single episodes of major depressive disorder. Manic patients predominated, and recurrent manic disorder was much more frequent than either recurrent depressive or bipolar disorder. The manic and bipolar patients were younger. Females predominated in all five groups of patients. The two manic groups were less likely to be married, but this was probably a reflection of their younger age. No differences were demonstrated with regard to educational status or occupation. There were no significant differences with regard to sibship position, family size, or polygamous/monogamous parents. Manic patients were more likely to have suffered permanent separation from one or both parents before the age of 12 years. A relatively low proportion of the patients had a positive history of mental disorder among first- or second-degree relatives. Manic and bipolar patients tended to present in hospital relatively early in their illness.

    The paper discusses to which extent climatic and seasonal effects can influence living habits and socio-economic activities in such a way that consequences of a nuclear accident might be affected. A number of examples from Sweden are given, related to dwellings (building standards and location), diet, seasonal effects in agriculture and tourism. The reindeer are discussed separately. Although climate and season do change man's habits in a way relevant to accident consequences, the conclusion of this paper is that in most cases this mechanism is severely mixed with other, sometimes more important ones

    Full Text Available Abstract Background In older adults, depression has been associated with increased fall risk, but the reasons for this link are not fully clear. Given parallels between major depression and Parkinson's disease, we hypothesized that major depression and related affective disorders would be associated with impairment in the ability to regulate the stride-to-stride fluctuations in gait cycle timing. Methods We measured stride-to-stride fluctuations of patients with two forms of mood disorders, unipolar major depressive disorder (MDD and bipolar disorder, and compared their gait to that of a healthy control group. The primary outcomes were two measures of gait unsteadiness that have been associated with fall risk: stride time variability and swing time variability. Results Compared to the control group, the two patient groups tended to walk more slowly and with decreased swing time and increased stride time. However, none of these differences was statistically significant. Compared to the control group, swing time variability was significantly larger in the subjects with bipolar disorder (p Conclusions Patients with MDD and patients with bipolar disorder display gait unsteadiness. This perturbation in gait may provide a mechanistic link connecting depression and falls. The present findings also suggest the possibility that measurement of variability of gait may provide a readily quantifiable objective approach to monitoring depression and related affective disorders.

    The serotonin system is undoubtedly involved in the pathogenesis of major depressive disorder (MDD). More specifically the serotonin transporter (SERT) serves as a major target for antidepressant drugs. There are conflicting results about SERT availability in depressed patients versus healthy controls. We aimed to measure SERT availability and study the effects of age, gender and season of scanning in MDD patients in comparison to healthy controls. We included 49 depressed outpatients (mean{+-}SD 42.3 {+-} 8.3 years) with a Hamilton depression rating scale score above 18, who were drug-naive or drug-free for {>=}4 weeks, and 49 healthy controls matched for age ({+-}2 years) and sex. Subjects were scanned with single photon emission computed tomography (SPECT) using [{sup 123}I]{beta}-CIT. SERT availability was expressed as specific to nonspecific binding ratios (BP{sub ND}) in the midbrain and diencephalon with cerebellar binding as a reference. In crude comparisons between patients and controls, we found no significant differences in midbrain or diencephalon SERT availability. In subgroup analyses, depressed males had numerically lower midbrain SERT availability than controls, whereas among women SERT availability was not different (significant diagnosis x gender interaction; p = 0.048). In the diencephalon we found a comparable diagnosis x gender interaction (p = 0.002) and an additional smoking x gender (p = 0.036) interaction. In the midbrain the season of scanning showed a significant main effect (p = 0.018) with higher SERT availability in winter. Differences in SERT availability in the midbrain and diencephalon in MDD patients compared with healthy subjects are affected by gender. The season of scanning is a covariate in the midbrain. The diagnosis x gender and gender x smoking interactions in SERT availability should be considered in future studies of the pathogenesis of MDD. (orig.)

    This study was carried out in order to determine the effects of different combinations of on-farm fasting intervals (8, 12, 16, 20 h) and 1.5 h of transport plus lairage periods (1, 3, 6 h) at different seasons (summer/winter) on blood stress parameters (cortisol and lactate), stomach content and weight, skin lesion and meat quality in a total of 960 pigs from eight farms. Blood lactate levels were greater in the summer (P < 0.001) and stomach content was affected (P < 0.05) by season, on-farm fasting interval (P < 0.001), lairage time (P < 0.0001). Stomach content weight reduces as the total feed withdrawal time increases up to on-farm fasting of 17 and 1 h of lairage. Stomach content can be influenced by feed and water in different ways according to treatments. Only 8 h of on-farm fasting is not enough to empty stomachs from feed content. However, an on-farm fasting period of 16 h or longer can also increase the occurrence of more water in the stomachs. Carcass lesions caused by fighting were greater (P ≤ 0.005) in the winter, mainly after 3 and 6 h of lairage (P ≤ 0.005). Loin and ham pHu was lower (P ≤ 0.05) for pigs slaughtered after 6 h of lairage during the summer. The application of 12 h of on-farm fasting with 6 h of lairage seemed to be best combination to reduce stomach content weight (feed and water). In the winter, shorter lairage period can be used to reduce percentage of skin lesions and better pork quality traits in pigs.

  2. Seasonality Affects the Diversity and Composition of Bacterioplankton Communities in Dongjiang River, a Drinking Water Source of Hong Kong

    Full Text Available Water quality ranks the most vital criterion for rivers serving as drinking water sources, which periodically changes over seasons. Such fluctuation is believed associated with the state shifts of bacterial community within. To date, seasonality effects on bacterioplankton community patterns in large rivers serving as drinking water sources however, are still poorly understood. Here we investigated the intra-annual bacterial community structure in the Dongjiang River, a drinking water source of Hong Kong, using high-throughput pyrosequencing in concert with geochemical property measurements during dry, and wet seasons. Our results showed that Proteobacteria, Actinobacteria, and Bacteroidetes were the dominant phyla of bacterioplankton communities, which varied in composition, and distribution from dry to wet seasons, and exhibited profound seasonal changes. Actinobacteria, Bacteroidetes, and Cyanobacteria seemed to be more associated with seasonality that the relative abundances of Actinobacteria, and Bacteroidetes were significantly higher in the dry season than those in the wet season (p < 0.01, while the relative abundance of Cyanobacteria was about 10-fold higher in the wet season than in the dry season. Temperature and NO3--N concentration represented key contributing factors to the observed seasonal variations. These findings help understand the roles of various bacterioplankton and their interactions with the biogeochemical processes in the river ecosystem.

  3. Development of an integrated model of personality, personality disorders and severe axis I disorders, with special reference to major affective disorders.

    A unidimensional model of the relationships between normal temperament, psychopathic variants of it and the two main forms of so-called endogenous psychoses (major affective disorders and schizophrenia) was derived from Kretschmer's constitutional typology. It was, however, not confirmed by means of a biometric approach nor was Kretschmer's broad concept of cyclothymia as a correlate of physical stoutness on the one hand and major affective disorders on the other supported by empirical data. Yet the concept of the 'melancholic type' of personality of patients with severe unipolar major depression (melancholia) which resembles descriptions by psychoanalysts could be corroborated. This was also true for the 'manic type' of personality as a (premorbid) correlate of predominantly manic forms of a bipolar I disorder. As predicted from a spectrum concept of major affective disorders, the ratio of traits of either type co-varied with the ratio of the depressive and the manic components in the long-term course of such a disorder. The two types of premorbid personality and a rare variant of the 'manic type', named 'relaxed, easy-going type', were conceived as 'affective types' dominating in major affective disorders. They are opposed to three 'neurotoid types' prevailing in so-called neurotic disorders as well as in schizophrenic psychoses. The similarity among the types can be visualized as spatial relationships in a circular, i.e. a two-dimensional, model (circumplex). Personality disorders as maladapted extreme variants of personality are, by definition, located outside the circle, mainly along its 'neurotoid' side. However, due to their transitional nature, axis I disorders cannot be represented adequately within the plane which represents (adapted as well as maladapted) forms of habitual behaviour (personality types and disorders, respectively). To integrate them into the spatial model of similarity interrelations, a dimension of actual psychopathology has to be added

    This study aims to investigate whether: familial history of affective disorder, subclinical depressive symptoms and life events (LEs) are predictive of a later development of mood disorder (onset). In a high-risk study, 234 healthy monozygotic and dizygotic twins with and without a co-twin history...... of affective disorder (high and low risk twins, respectively) were identified through nationwide registers and assessed from 2002 to 2005. Participants were followed longitudinally at 6-months intervals for up to nine years and finally reassessed with a personal interview to obtain information on whether...... they had an onset. During the follow-up period (mean time 7.0 years), 36 participants (15.4%) developed onset. Onset was significantly associated with risk status (Hazard ratio (HR) = 1.38, 95% CI 1.08-1.76), female sex, HR = 2.70, 95% CI 1.19-6.97, age HR = 0.97, 95% CI 0.93-0.99), and also with baseline...

    Previous studies of borderline personality disorder report neuropsychological impairments in several domains, including memory. No studies have compared memory functioning in high-risk prisoners with borderline personality disorder with similar prisoners with other personality disorders. To explore mnemonic impairments in prisoners undergoing personality assessment as part of the dangerous and severe personality disorder initiative or detained in a medium secure facility. We investigated memory function in 18 prisoners with borderline personality disorder and 18 prisoners with other personality disorders. Prisoners with borderline personality disorder exhibited a pattern of multi-modal impairments in the immediate and delayed recall of verbal and visual information, with some association with affective instability. These deficits were not associated with the severity of personality disturbance. These data suggest that memory deficits have some specificity in relation to the constituent traits of borderline personality disorder and indicate that neuropsychological assessment may be a source of useful adjunctive information for distinguishing between the cognitive and psychological difficulties of individual prisoners.

    Comorbidity of anxiety and affective disorders in people with a diagnosis of schizophrenia is common. This study investigated the hypothesis that greater negative beliefs about illness and lower self-esteem will be significantly associated with the presence of anxiety or affective comorbidity in a sample of persons (n = 138) diagnosed with schizophrenia. The Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition; the Positive and Negative Syndrome Scale; the Global Assessment of Functioning Scale; the Personal Beliefs about Illness Questionnaire; and the Rosenberg Self-Esteem Scale were all completed for each participant. Of the total sample, 62 (44.9%) had a comorbid anxiety or affective disorder. Logistic regression revealed that those with a comorbid anxiety or affective disorder had significantly lower levels of functioning (Global Assessment of Functioning), more negative appraisals of entrapment in psychosis (Personal Beliefs about Illness Questionnaire), and lower levels of self-esteem (Rosenberg Self-Esteem Scale). Although further research is required, the strong association between personal beliefs about self and illness and comorbidity suggests that negative beliefs about psychotic experiences and self-esteem may be linked to the development and maintenance of anxiety and affective comorbid conditions among people with a diagnosis of schizophrenia or the like.

    In this study, two successive field trials were conducted during the non-breeding season to investigate various factors affecting on fertility of Suffolk ewes after intrauterine insemination with frozen-thawed semen. In the first year (Experiment 1), three sperm numbers per insemination dose (0.25, 0.5 and 1 million sperm) and five sheep farms were used, and in the second year (Experiment 2), parity, age, body weight, body condition score (BCS) and postpartum days were investigated to compare pregnancy and lambing rates. High pregnancy and lambing rates (70.6 and 70.6%, respectively) were obtained with 0.25 million sperm per dose. There were no significant differences in the pregnancy and lambing rates among the five farms, but there was a tendency for one farm to have higher pregnancy (75.8%, P=0.065) and lambing (72.7%, P=0.077) rates than those (46.7-53.3% and 45.2-53.3% for the pregnancy and lambing rates, respectively) of the other farms. In Experiment 2, ewe age significantly affected both the pregnancy and lambing rates. Nulliparous ewes had a higher lambing rate (72.0%) than that (44.2%) of multiparous ewes, but a significant difference was not revealed. Regardless of body weight, BCS tended to be an important factor influencing on fertility of ewes. Body weight and the postpartum days did not affect the fertility of ewes. It was concluded from these results that the fertility of Suffolk ewes after intrauterine insemination with frozen semen was significantly influenced by sperm number per dose and ewe age. Nulliparous ewes at less than three years of age and with a BCS of more than 3.0 are expected to have higher fertility than other ewes.

    Full Text Available BACKGROUND: The bi-relationships between psychological stress, negative affect and disordered eating has been well studied in western culture, while tri-relationship among them, i.e. how some of those factors influence these bi-relationships, has rarely been studied. However, there has been little related study in the different Chinese culture. This study was conducted to investigate the bi-relationships and tri-relationship between psychological stress, negative affect, and disordered eating attitudes and behaviors in young Chinese women. METHODOLOGY: A total of 245 young Chinese policewomen employed to carry out health and safety checks at the 2010 Shanghai World Expo were recruited in this study. The Chinese version of the Perceived Stress Scale (PSS-10, Beck Depression Inventory Revised (BDI-II, Beck Anxiety Inventory (BAI, and Eating Attitude Test (EAT-26 were administered to all participants. PRINCIPAL FINDINGS: The total scores of PSS-10, BDI-II and BAI were all highly correlated with that of EAT-26. The PSS-10 score significantly correlated with both BDI-II and BAI scores. There was no statistically significant direct effect from perceived stress to disordered eating (-0.012, 95%CI: -.038~0.006, p=0.357, however, the indirect effects from PSS-10 via affect factors were statistically significant, e.g. the estimated mediation effects from PSS to EAT-26 via depression and anxiety were 0.036 (95%CI: 0.022~0.044, p<0.001 and 0.015 (95%CI: 0.005~0.023, p<0.01, respectively. CONCLUSIONS: Perceived stress and negative affects of depression and anxiety were demonstrated to be strongly associated with disordered eating. Negative affect mediated the relationship between perceived stress and disordered eating. The findings suggest that effective interventions and preventative programmes for disordered eating should pay more attention to depression and anxiety among the young Chinese female population.

    Full Text Available Abstract Background Longitudinal, population-based, research is important if we are to better characterize the lifetime patterns and determinants of affective disorders. While studies of this type are becoming increasingly prevalent, there has been little discussion about the limitations of the methods commonly used. Methods Discussion paper including a brief review of key prospective population-based studies as the basis for a critical appraisal of current approaches. Results We identified a number of common methodological weaknesses that restrict the potential of longitudinal research to characterize the diversity, prognosis, and determinants of affective disorders over time. Most studies using comprehensive diagnostic instruments have either been of relatively brief duration, or have suffered from long periods between waves. Most etiologic research has focused on first onset diagnoses, although these may be relatively uncommon after early adulthood and the burden of mental disorders falls more heavily on individuals with recurring disorders. Analysis has tended to be based on changes in diagnostic status rather than anges in symptom levels, limiting study power. Diagnoses have generally been treated as homogeneous entities and few studies have explored whether diagnostic subtypes such as atypical depression vary in their etiology or prognosis. Little research has considered whether there are distinct trajectories of symptoms over time and most has focused on individual disorders such as depression, rather than considering the relationship over time between symptoms of different affective disorders. There has also been limited longitudinal research on factors in the physical or social environment that may influence the onset, recurrence or chronicity of symptoms. Conclusion Many important, and in some respects quite basic, questions remain about the trajectory of depression and anxiety disorders over the life course and the factors that

    This study was performed with an aim to understand the conditions causing the ambivalence of the person with bipolar affective disorder (BAD) regarding following the drug treatment. A qualitative approach was used, with the Grounded Theory as the methodology framework, under the light of Symbolic Interactionism. Participants were 14 individuals with BAD who were being followed at an Outpatient Clinic for Mood Disorders of a university hospital and 14 relatives they indicated. Interviews and observation were the main forms of obtaining data. Results revealed three categories that described the referred causal conditions: experiencing the crises of the disorder; needing the drug; and living with the side effects of the drugs. It was found that there is a need to change the attitude of some health professionals from blaming the patient for interrupting the treatment to one of listening, valuing their symbolic and affective universe as well as the partnership in the treatment.

    Five patients (4 women) with Parkinson's disease (PD) and primary major psychiatric disorder (PMPD) meeting DSM-IV criteria for the diagnosis of bipolar affective disorder (BAD) were studied. Four patients had early onset PD. Four developed a severe psychiatric disorder a few years after starting dopaminergic therapy in presence of a mild motor disability and a mild cognitive impairment, with no evidence of cerebral atrophy at CT or MRI. Two patients developed a clear manic episode; the other three presented a severe depressive episode (in one case featuring a Cotard syndrome). None showed previous signs of long term L-dopa treatment syndrome (LTS), hallucinosis or other minor psychiatric disorders. The two manic episodes occurred shortly after an increase of dopaminergic therapy and in one case rapid cyclic mood fluctuations were observed. At the onset of psychiatric symptoms, all patients had an unspecific diagnosis of chronic delusional hallucinatory psychosis (CDHP).

    Maternal and newborn health disparities and the health impacts of climate change present grand challenges for global health equity, and there remain knowledge gaps in our understanding of how these challenges intersect. This study examines the pathways through which mothers are affected by seasonal and meteorological factors in sub-Saharan Africa in general, and Kanungu District (Uganda), in particular. We conducted a community-based study consisting of focus group discussions with mothers and interviews with health care workers in Kanungu District. Using a priori and a posteriori coding, we found a diversity of perspectives on the impacts of seasonal and weather exposures, with reporting of more food available in the rainy season. The rainy season was also identified as the period in which women performed physical labour for longer time periods, while work conditions in the dry season were reported to be more difficult due to heat. The causal pathways through which weather and seasonality may be affecting size at birth as reported by Kanungu mothers were consistent with those most frequently reported in the literature elsewhere, including maternal energy balance (nutritional intake and physical exertion output) and seasonal illness. While both Indigenous and non-Indigenous mothers described similar pathways, however, the severity of these experiences differed. Non-Indigenous mothers frequently relied on livestock assets or opportunities for less taxing physical work than Indigenous women, who had fewer options when facing food shortages or transport costs. Findings point to specific entry points for intervention including increased nutritional support in dry season periods of food scarcity, increased diversification of wage labour opportunities, and increased access to contraception. Interventions should be particularly targeted towards Indigenous mothers as they face greater food insecurity, may have fewer sources of income, and face greater overall deprivation

  18. A Lagrangian identification of the main sources of moisture affecting northeastern Brazil during its pre-rainy and rainy seasons.

    Directory of Open Access Journals (Sweden)

    Anita Drumond

    Full Text Available This work examines the sources of moisture affecting the semi-arid Brazilian Northeast (NEB during its pre-rainy and rainy season (JFMAM through a Lagrangian diagnosis method. The FLEXPART model identifies the humidity contributions to the moisture budget over a region through the continuous computation of changes in the specific humidity along back or forward trajectories up to 10 days period. The numerical experiments were done for the period that spans between 2000 and 2004 and results were aggregated on a monthly basis. Results show that besides a minor local recycling component, the vast majority of moisture reaching NEB area is originated in the south Atlantic basin and that the nearby wet Amazon basin bears almost no impact. Moreover, although the maximum precipitation in the "Poligono das Secas" region (PS occurs in March and the maximum precipitation associated with air parcels emanating from the South Atlantic towards PS is observed along January to March, the highest moisture contribution from this oceanic region occurs slightly later (April. A dynamical analysis suggests that the maximum precipitation observed in the PS sector does not coincide with the maximum moisture supply probably due to the combined effect of the Walker and Hadley cells in inhibiting the rising motions over the region in the months following April.

    Didymosphenia geminata (didymo) was introduced into a New Zealand river in 2004, and since then has dramatically spread to cover the beds of many rivers with extremely dense and extensive mats. Successful management is hampered by the fact that much is still unknown about the factors affecting the growth of this nuisance species. We synthesized available data on the distribution of D. geminata in New Zealand rivers to determine how physical and chemical system conditions (flow, bed disturbance, nutrients, and light) affect the growth and persistence of this organism. Here we assess results from bi-weekly surveys performed over a full year on two rivers where didymo was first observed in New Zealand; the Oreti and Mararoa. We used the data to test the hypotheses that the development of thick, dense mats requires high light levels but is inversely proportional to nutrient levels, and that mat persistence is controlled by the frequency of flow events that produce bed sediment transport. Observed regrowth between disturbance events was found to be inversely correlated with nutrient availability. The seasonal availability of light did not correlate with variations in growth rate, but this did not account for specific characteristics of the different sites such as aspect, shading, flow depth and turbidity that will all impact on the amount of available light reaching the streambed. The results clearly indicate that the time-history of flow and nutrient levels is critical to evaluating the growth and persistence of D. geminata and that additional site specific information is necessary to determine the role of bed stability and the amount of available light reaching the streambed.

  20. The tale of the shrinking weapon: seasonal changes in nutrition affect weapon size and sexual dimorphism, but not contemporary evolution.

    Sexually selected traits are often highly variable in size within populations due to their close link with the physical condition of individuals. Nutrition has a large impact on physical condition, and thus, any seasonal changes in nutritional quality are predicted to alter the average size of sexually selected traits as well as the degree of sexual dimorphism in populations. However, although traits affected by mate choice are well studied, we have a surprising lack of knowledge of how natural variation in nutrition affects the expression of sexually selected weapons and sexual dimorphism. Further, few studies explicitly test for differences in the heritability and mean-scaled evolvability of sexually selected traits across conditions. We studied Narnia femorata (Hemiptera: Coreidae), an insect where males use their hind legs as weapons and the femurs are enlarged, to understand the extent to which weapon expression, sexual dimorphism and evolvability change across the actual range of nutrition available in the wild. We found that insects raised on a poor diet (cactus without fruit) are nearly monomorphic, whereas those raised on a high-quality diet (cactus with ripe fruit) are distinctly sexually dimorphic via the expression of large hind leg weapons in males. Contrary to our expectations, we found little evidence of a potential for evolutionary change for any trait measured. Thus, although we show weapons are highly condition dependent, and changes in weapon expression and dimorphism could alter evolutionary dynamics, our populations are unlikely to experience further evolutionary changes under current conditions. © 2016 European Society For Evolutionary Biology.

  1. Delinquency as a mediator of the relation between negative affectivity and adolescent alcohol use disorder.

    This investigation examined mediators of the longitudinal relation between negative affectivity and the development of problematic drinking behavior in adolescent boys and girls. In the present study, 499 early adolescents completed inventories of negative affectivity, attitudes toward delinquency, personal delinquency, and affiliation with delinquent peers. Positive attitudes toward delinquency emerged as the most consistent mediator and strongly predicted drinking frequency in various situations. Compared with personal delinquency, both attitudes toward delinquency and peer delinquency were superior predictors of affect-related drinking. Our results also demonstrated that positive attitudes toward delinquency mediated the relation between negative affectivity and later development of an alcohol use disorder. These findings suggest that a proneness to unpleasant affect impacts adolescent drinking by heightening risk for general rejection of normative behavior, rather than by increasing drinking as a means of managing affect. The importance and implications of testing delinquency variables together in the same model are discussed.

    Defining disease and disorder remains a key conceptual question in philosophy of medicine and psychiatry, and is currently a very practical matter for psychiatric nosology, given the new Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and the upcoming International Classification of Diseases, 11th Revision. There have been advances in the cognitive-affective science of human categorization, and it is timely to consider implications for our understanding of the category of psychiatric disorder. The category of mental disorder has graded boundaries, and conditions within this category can be conceptualized using MEDICAL or MORAL metaphors. One key set of constructs used in MEDICAL metaphors relates to the notion of dysfunction, and it may, in turn, be useful to conceptualize such dysfunction in evolutionary terms. For typical disorders, it is relatively easy to agree that dysfunction is present. However, for atypical disorders, there may be considerable debate about the presence and extent of dysfunction. Rational arguments can be brought to bear to help decide whether particular entities should be included in our nosologies, and, if so, what their boundaries should be. However, it is appropriate that there should be ongoing debate on diagnostic validity, clinical utility, and other relevant facts and values, for cases that are difficult to decide. The perspective here can be illustrated using many nosological debates within the anxiety disorders and the obsessive-compulsive and related disorders, including the question of delineating normal from abnormal anxiety, of deciding whether anxiety is psychiatric or medical, and the debate about the optimal meta-structure for anxiety disorders.

    Joint effects of genotype and the environment have turned out to be significant in the development of psychotic disorders. The purpose of the present study was to assess the association of an adoptive child׳s thought and schizophrenia spectrum disorders with genetic and environmental risk indicators and their interactions. A subgroup of the total sample used in the Finnish Adoptive Family Study was considered in the present study. The subjects were 125 adoptees at a high (n=53) or low (n=72) genetic risk of schizophrenia spectrum disorders and their adoptive parents. The risk factors evaluated were the adoptive child's genetic risk for schizophrenia spectrum disorders, winter or spring birth and parental Communication Deviance (CD). Thought disorders in the adoptees were assessed using the Thought Disorder Index and diagnoses were made according to DSM-III-R criteria. The adoptive child׳s Thought Disorder Index was only associated with parental Communication Deviance. The adoptive child's heightened genetic risk or winter or spring birth or parental CD or their interactions did not predict the adoptee's schizophrenia spectrum disorder. The results suggest that studies taking several risk indicators and their interactions into account may change views on the mutual significance of well-known risk factors. Copyright © 2015.

    1992-02-01

    Three economic factors were identified which influence the seasonality of gas prices: fuel switching, storage, and utilization of wellhead deliverability. Also, contract structures will have an influence on the seasonality of natural gas prices. Increases in the utilization of wellhead deliverability tends to increase the seasonality of gas prices. Price-induced fuel switching capability is too small to significantly influence the seasonality of gas prices. If there is adequate deliverability, the cost of interruptible storage, including carry cost, will place a ceiling on the seasonability of gas prices. This cost is about $.70 per MMBtu. If deliverability tightens, then the cost of firm storage or producer shut-ins will place a ceiling on gas prices. The ceiling would range from $1.00 to $1.20 per MMBtu. There is concern about whether the current market structure will provide for a smooth return to full cycle pricing. The current premiums for new contracts are inadequate to achieve this objective

    Lifetime prevalence of psychotic disorders varies widely across studies. Epidemiological surveys have rarely examined prevalences of specific psychotic disorders other than schizophrenia, and the majority used a single-phase design without employing clinical reappraisal interview for diagnostic verification. The current study investigated lifetime prevalence, correlates and service utilization of schizophrenia-spectrum, affective, and other non-affective psychotic disorders in a representative sample of community-dwelling Chinese adult population aged 16-75 years (N = 5719) based on a territory-wide, population-based household survey for mental disorders in Hong Kong. The survey adopted a 2-phase design comprising first-phase psychosis screening and second-phase diagnostic verification incorporating clinical information from psychiatrist-administered semi-structured interview and medical record review to ascertain DSM-IV lifetime diagnosis for psychotic disorders. Data on sociodemographics, psychosocial characteristics and service utilization were collected. Our results showed that lifetime prevalence was 2.47% for psychotic disorder overall, 1.25% for schizophrenia, 0.15% for delusional disorder, 0.38% for psychotic disorder not otherwise specified, 0.31% for bipolar disorder with psychosis, and 0.33% for depressive disorder with psychosis. Schizophrenia-spectrum disorder was associated with family history of psychosis, cigarette smoking and variables indicating socioeconomic disadvantage. Victimization experiences were significantly related to affective psychoses and other non-affective psychoses. Around 80% of participants with any psychotic disorder sought some kind of professional help for mental health problems in the past year. Using comprehensive diagnostic assessment involving interview and record data, our results indicate that approximately 2.5% of Chinese adult population had lifetime psychotic disorder which represents a major public health concern.

  6. Intrinsically Disordered Segments Affect Protein Half-Life in the Cell and during Evolution

    2014-09-01

    Full Text Available Precise control of protein turnover is essential for cellular homeostasis. The ubiquitin-proteasome system is well established as a major regulator of protein degradation, but an understanding of how inherent structural features influence the lifetimes of proteins is lacking. We report that yeast, mouse, and human proteins with terminal or internal intrinsically disordered segments have significantly shorter half-lives than proteins without these features. The lengths of the disordered segments that affect protein half-life are compatible with the structure of the proteasome. Divergence in terminal and internal disordered segments in yeast proteins originating from gene duplication leads to significantly altered half-life. Many paralogs that are affected by such changes participate in signaling, where altered protein half-life will directly impact cellular processes and function. Thus, natural variation in the length and position of disordered segments may affect protein half-life and could serve as an underappreciated source of genetic variation with important phenotypic consequences.

  7. Association between the dopamine D3 receptor gene locus (DRD3) and unipolar affective disorder.

    Dopamine neurotransmission has been implicated in the pathophysiology of schizophrenia and, more recently, affective disorders. Among the dopamine receptors, D3 can be considered as particularly related to affective disorders due to its neuroanatomical localization in the limbic region of the brain and its relation to the serotoninergic activity of the CNS. The possible involvement of dopamine receptor D3 in unipolar (UP) major depression was investigated by a genetic association study of the D3 receptor gene locus (DRD3) on 36 UP patients and 38 ethnically matched controls. An allelic association of DRD3 (Bal I polymorphism) and UP illness was observed, with the Gly-9 allele (allele '2', 206/98 base-pairs long) being more frequent in patients than in controls (49% vs 29%, P < 0.02). The genotypes containing this allele (1-2 and 2-2) were found in 75% of patients vs 50% of controls (P < 0.03, odds ratio = 3.00, 95% CI = 1.12-8.05). The effect of the genotype remained significant (P < 0.02) after sex and family history were controlled by a multiple linear regression analysis. These results further support the hypothesis that dopaminergic mechanisms may be implicated in the pathogenesis of affective disorder. More specifically, the '2' allele of the dopamine receptor D3 gene seems to be associated with unipolar depression and can be considered as a 'phenotypic modifier' for major psychiatric disorders.

    Full Text Available Neurocysticercosis is a common parasitic infection in India presenting usually with seizues, headache, focal neurological deficits. Neurocysticercosis presenting as a psychiatric illness is rare. Disseminated cysticercosis with involvement of central nervous system and head and neck muscles is rare even in endemic areas. We present a case of disseminated cysticercosis, which presented with chronic tension type headache and affective mood disorder. Treatment with cysticidal drugs led to complete remission of psychiatric complaints. In endemic areas history suggestive of mood disorder should not be used as supportive evidence of a primary headache syndome like tension type headche without ruling out secondary causes. Making an early diagnosis can prevent morbidity.

    To examine whether genes that predispose to schizophrenia also confer a predisposition to other psychiatric disorders such as bipolar affective disorder (BAD), we tested for linkage between the recently identified schizophrenia susceptibility locus D6S260 and the inheritance of BAD in 12 large Australian pedigrees. We found no evidence for linkage over a region of 12-27 cM from the D6S260 locus, depending on the model used. Our results therefore do not provide support for the continuum theory of psychosis. 13 refs., 2 tabs.

    Insect bite hypersensitivity (IBH) in horses is a seasonal, IgE-mediated, pruritic skin disorder primarily caused by Culicoides spp. We hypothesize that a mixed Th2/Th1-type immune status, off season, alters into Th2-dominated immune reactivity in the skin of IBH-affected ponies in the IBM season.

  12. Phenological patterns of Spodoptera Guenée, 1852 (Lepidoptera: Noctuidae) is more affected by ENSO than seasonal factors and host plant availability in a Brazilian Savanna

    The identification of factors responsible for the population dynamics is fundamental for pest management, since losses can reach 18% of annual production. Besides regular seasonal environmental factors and crop managements, additional supra-annual meteorological phenomena can also affect population dynamics, although its relevance has been rarely investigated. Among crop pests, Spodoptera stands out due to its worldwide distribution, high degree of polyphagy, thus causing damages in several crops in the world. Aiming to distinguish the relevance of different factors shaping population dynamics of Spodoptera in an ecosystem constituted of dry and rainy seasons, the current study used circular statistics to identify phenological patterns and test if its population fluctuation is driven by El Niño-Southern Oscillation (ENSO) effect, seasonal meteorological parameters, and/or host plant availability. Samplings were done in an intercropping system, in the Brazilian Savanna, during the new moon cycles between July/2013 and June/2016. Species were recorded all year round, but demonstrated differently non-uniform distribution, being concentrated in different seasons of the year. Population fluctuations were mostly affected by the ENSO intensity, despite the contrasting seasonal meteorological variation or host plant availability in a 400-m radius. Studies involving the observation of supra-annual phenomena, although rare, reach similar conclusions in relation to Neotropical insect fauna. Therefore, it is paramount to have long-term sampling studies to obtain a more precise response of the pest populations towards the agroecosystem conditions.

    High numbers of employees are coping with affective disorders. At the same time, ambitiousness, achievement striving and a strong sense of personal control and responsibility are personality characteristics that are nowadays regarded as key to good work functioning, whereas social work circumstances tend to be neglected. However, it is largely unkown how personality characteristics and work circumstances affect work functioning when facing an affective disorder. Given the high burden of affective disorders on occupational health, we investigate these issues in the context of affective disorders and absenteeism from work. The principal aim of this paper is to examine whether particular personality characteristics that reflect self-governance (conscientiousness and mastery) and work circumstances (demands, control, support) influence the impact of affective disorders on long-term absenteeism (>10 working days). Baseline and 1-year follow-up data from 1249 participants in the Netherlands Study of Depression and Anxiety (NESDA) in 2004-2006 was employed. Multivariate logistic regression analyses were performed, including interaction effects between depressive, anxiety, and comorbid disorders and personality and work circumstances. In general, mastery and conscientiousness increased nor diminished odds of subsequent long-term absenteeism, whereas higher job support significantly decreased these odds. Interaction effects showed that the impact of affective disorders on absenteeism was stronger for highly conscientious employees and for employees who experienced high job demands. Affective disorders may particularly severely affect work functioning of employees who are highly conscientious or face high psychological job demands. Adjusting working conditions to their individual needs may prevent excessive work absence.

    Neuropsychological studies have provided evidence for deficits in psychiatric disorders, such as schizophrenia and mood disorders. However, neuropsychological function in Panic Disorder (PD) or PD with a comorbid diagnosis of Major Depressive Disorder (MDD) has not been comprehensively studied. The present study investigated neuropsychological functioning in patients with PD and PD + MDD by focusing on tasks that assess attention, psychomotor speed, executive function, decision-making, and affective processing. Twenty-two unmedicated patients with PD, eleven of whom had a secondary diagnosis of MDD, were compared to twenty-two healthy controls, matched for gender, age, and intelligence on tasks of attention, memory, psychomotor speed, executive function, decision-making, and affective processing from the Cambridge Neuropsychological Test Automated Battery (CANTAB), Cambridge Gamble Task, and Affective Go/No-go Task. Relative to matched healthy controls, patients with PD + MDD displayed an attentional bias toward negatively-valenced verbal stimuli (Affective Go/No-go Task) and longer decision-making latencies (Cambridge Gamble Task). Furthermore, the PD + MDD group committed more errors on a task of memory and visual discrimination compared to their controls. In contrast, no group differences were found for PD patients relative to matched control subjects. The sample size was limited, however, all patients were drug-free at the time of testing. The PD + MDD patients demonstrated deficits on a task involving visual discrimination and working memory, and an attentional bias towards negatively-valenced stimuli. In addition, patients with comorbid depression provided qualitatively different responses in the areas of affective and decision-making processes.

    Maternal pre-pregnancy obesity has been linked with an increased risk for negative emotionality and inattentiveness in offspring in early childhood. The aim of this study was to examine the association between maternal pre-pregnancy body mass index (BMI) and the development of affective problems (dysthymic disorder, major depressive disorder) throughout childhood and adolescence. In the Western Australian Pregnancy Cohort (Raine) Study, 2900 women provided data on their pre-pregnancy weight, and height measurements were taken at 18 weeks of gestation. BMI was calculated and categorized using standardized methods. Live-born children (n = 2868) were followed up at ages 5, 8, 10, 14 and 17 years using the Diagnostic and Statistical Manual of Mental Disorders-oriented scales of the Child Behavior Checklist (CBCL/4-18). Longitudinal models were applied to assess the relationships between maternal pre-pregnancy BMI and affective problems from age 5 through 17. There was a higher risk of affective problems between the ages of 5 and 17 years among children of women who were overweight and obese compared with the offspring of women in the healthy pre-pregnancy weight range (BMI 18.5-24.99) after adjustment for confounders, including paternal BMI. Maternal pre-pregnancy overweight and obesity may be implicated in the development of affective problems, including depression, in their offspring later in life.

    Although several studies suggest that negative affect and interpersonal problems serve as important contributors for eating-related problems, much of this research has been conducted among women and less is known about their roles in precipitating and maintaining eating problems among men. Previous studies with undergraduate men suggest that difficulties in emotion regulation are associated with disordered eating even after controlling for differences in body mass index (BMI) and negative affect. The present study sought to replicate these findings and extend them to assess any unique variance explained by problems in interpersonal functioning among both men and women. Participants were men (n=213) and women (n=521) undergraduates at a large Midwestern university who completed a demographic information form, the Eating Disorder Examination-Questionnaire (EDE-Q), the Difficulties in Emotion Regulation Scale (DERS), the Positive and Negative Affect Schedule, and the Inventory of Interpersonal Problems-Short Circumplex Form (IIP-SC). A series of hierarchical regression analyses indicated that DERS and IIP-SC significantly predicted EDE-Q global scores after controlling for variability in BMI and negative affect and that the results were similar for men and women. Our findings offer preliminary support for models that highlight emotional vulnerability and interpersonal problems for disordered eating for young adult men. Future research extending these findings among treatment-seeking samples and employing multi-method assessment would serve to further clarify the tenability of these theoretical models for both men and women.

    Severinsen, Jacob; Bjarkam, Carsten; Kiær-Larsen, Stine

    Introduction: Linkage studies suggest that chromosome 22q12-13 may contain one or more shared susceptibility genes for schizophrenia (SZ) and bipolar affective disorder (BPD). In a Faeroese sample we previously reported association between microsatellite markers located at 22q13.31-qtel and both...... disorders. Methods: The present study reports an association analysis across 5 genes (including 14 single nucleotide and two microsatellite polymorphisms) in this interval using a case-control sample of 162 BPD, 103 SZ patients and 200 controls. Results: The bromodomain-containing 1 gene (BRD1), which...... encodes a putative regulator of transcription showed association with both disorders with minimal p-values of 0.0046 and 0.00001 for single marker and overall haplotype analysis, respectively. A specific BRD1 2-marker “risk” haplotype showed a frequency of ~10% in the combined case group versus ~1...

    Recognizing others' emotions is a fundamental social skill, widely impaired in psychiatric populations. These emotional dysfunctions are involved in the development and maintenance of alcohol-related disorders, but their differential intensity across emotions and their modifications during disease evolution remain underexplored. Affective prosody decoding was assessed through a vocalization task using six emotions, among 17 patients with severe alcohol use disorder, 16 Korsakoff syndrome patients (diagnosed following DSM-V criteria) and 19 controls. Significant disturbances in emotional decoding, particularly for negative emotions, were found in alcohol-related disorders. These impairments, identical for both experimental groups, constitute a core deficit in excessive alcohol use. Copyright © 2018 Elsevier B.V. All rights reserved.

    Children of parents with bipolar disorder (BD) are at heightened risk for developing mood and other psychiatric disorders. We proposed to evaluate the environment of families with at least one parent with BD type I (BDF) with affected offspring (aBDF) and unaffected offspring (uBDF) compared with control families without a history of DSM-IV Axis I disorder (CF). We used the Family Environment Scale (FES) to evaluate 47 BDF (aBDF + uBDF) and 30 CF. Parents were assessed through the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Diagnosis of the offspring was determined through the Schedule for Affective Disorders and Schizophrenia for School-Age Children/Present and Lifetime Version (K-SADS-PL) interview. There were statistically significant differences between aBDF, uBDF and CF in cohesion (p = 0.003), intellectual-cultural orientation (p = 0.01), active-recreational orientation (p = 0.007), conflict (p = 0.001), control (p = 0.01), moral-religious emphasis (p = 0.01) and organization (p = 0.001). The aBDF showed higher levels of control (p = 0.02) when compared to the uBDF. Families with a BD parent presented more dysfunctional interactions among members. Moreover, the presence of BD or other psychiatric disorders in the offspring of parents with BD is associated with higher levels of control. These results highlight the relevance of psychosocial interventions to improve resilience and family interactions.

    BACKGROUND: Links between thyroid function and depression have been noted in many contexts. We assessed whether hospitalization with hypothyroidism was a risk factor for developing affective disorder. METHODS: We conducted a prospective cohort study using historical data from Danish registers....... The observational period was 1977-1999. Three study cohorts were identified: all patients with a first hospital admittance with the resulting index discharge diagnoses hypothyroidism, osteoarthritis, or nontoxic goiter. A later hospitalization with a resulting discharge diagnosis of affective disorder was used...... as event of interest, and rates of readmission were estimated and compared using competing risk models in survival analyses. FINDINGS: We identified 165,307 patients discharged with an index diagnosis. In the observational period, 1041 events occurred. An index diagnosis of hypothyroidism was associated...

    According to Aaron Beck, dysfunctional thinking patterns appear also in euthymic patients, after withdrawal of acute diseases symptoms. Patients have a disordered, negative image of themselves, of their future and the surrounding world. It has been shown that a way a man perceives possessed social support has a basic meaning for him. The purpose of the research was to analyze the relationship between perceived social support and the patient's cognitive style. The study group consisted of euthymic outpatients diagnosed with recurrent depressive disorder (UID) or bipolar affective disorder (BID). Assessment of a cognitive style was made according to the Rosenberg Scale, Hopelessness Scale HS-20 and Automatique Thoughts Questionnaire ATQ 30, assessment of the amount of received support - according to Cohen's ISEL. The presented study revealed that, in both groups of patients, a thinking style is disturbed and that there is a link between a cognitive style and the perception of the level of received support. The link was stronger in the group of patients with unipolar affective disorder. In both groups, correlations concerning emotional support were the highest.

    [Purpose] This study aimed to examine the quality of life (QOL) of community-dwelling elderly women with musculoskeletal disorders and factors that affect it. [Subjects] The subjects were 27 community-dwelling elderly women with musculoskeletal disorders (mean age: 76.3 ± 7.4 years). Their physical and psychological conditions, QOL, and other characteristics were researched. [Methods] The Japanese version of Life-Space Assessment was used to assess the subjects' daily life activities; the Japanese version of Fall Efficacy Scale (FES), to assess their fear of falling; the Geriatric Depression Scale (GDS 15), to assess their depression status; and the Life Satisfaction Index K (LSIK), to assess their QOL. [Results] The results indicated that the number of family members living together, degree of pain, fear of falling, and depression affect the LSIK scores of the community-dwelling elderly women with musculoskeletal disorders. [Conclusion] The study results suggest that the LSIK scores of community-dwelling elderly women with musculoskeletal disorders can be improved by easing their pain, improving their physical abilities to prevent falls, and improving their mobility. The results also suggest that continuing rehabilitation treatment is required.

  4. Impaired neurocognitive functions affect social learning processes in oppositional defiant disorder and conduct disorder: implications for interventions.

    In this review, a conceptualization of oppositional defiant (ODD) and conduct disorder (CD) is presented according to which social learning processes in these disorders are affected by neurocognitive dysfunctions. Neurobiological studies in ODD and CD suggest that the ability to make associations between behaviors and negative and positive consequences is compromised in children and adolescents with these disorders due to reduced sensitivity to punishment and to reward. As a result, both learning of appropriate behavior and learning to refrain from inappropriate behavior may be affected. Likewise, problem solving is impaired due to deficiencies in inhibition, attention, cognitive flexibility, and decision making. Consequently, children and adolescents with ODD and CD may have difficulty learning to optimize their behavior in changeable environments. This conceptualization of ODD and CD is relevant for the improvement of the effect of psychological treatments. Behavioral and cognitive-behavioral interventions that have been shown to be modestly effective in ODD and CD are based on social learning. Limited effectiveness of these interventions may be caused by difficulties in social learning in children and adolescents with ODD and CD. However, although these impairments have been observed at a group level, the deficits in reward processing, punishment processing, and cognitive control mentioned above may not be present to the same extent in each individual with ODD and CD. Therefore, the neurocognitive characteristics in children and adolescents with ODD and CD should be assessed individually. Thus, instead of delivering interventions in a standardized way, these programs may benefit from an individualized approach that depends on the weaknesses and strengths of the neurocognitive characteristics of the child and the adolescent.

    Psychosocial relationships with parents, peers, and siblings, as well as school functioning, were measured at two points in time by parental interview in 21 prepubertal children: during an episode of major depression and after they had sustained an affective recovery from the index episode for at least four months. School functioning was completely normalized, but deficits in the child's intrafamilial and extra-familial relationships had improved only partially. The pattern of improvement was merely quantitative. Moderate deficits during the depressive episode reached, after affective recovery, the level of the normal control group. In contrast, severe deficits only improved to a moderate level of severity. It is suggested that treating the affective disorder is not sufficient in many children with major depression and that efficacy studies of psychotherapeutic interventions in affectively recovered children are needed.

    One in ten and one in three of people with affective disorders experience diabetes and metabolic syndrome respectively. Physical activity (PA) and sedentary behaviour (SB) are key risk factors that can ameliorate the risk of metabolic disease among this population. However, PA is often seen as luxury and/or a secondary component within the management of people with affective disorders. The current article provides a non-systematic best-evidence synthesis of the available literature, detailing a number of suggestions for the implementation of PA into clinical practice. Whilst the evidence is unequivocal for the efficacy of PA to prevent and manage metabolic disease in the general population, it is in its infancy in this patient group. Nonetheless, action must be taken now to ensure that PA and reducing SB are given a priority to prevent and manage metabolic diseases and improve wider health outcomes. PA should be treated as a vital sign and all people with affective disorders asked about their activity levels and if appropriate advised to increase this. There is a need for investment in qualified exercise specialists in clinical practice such as physiotherapists to undertake and oversee PA in practice. Behavioural strategies such as the self-determined theory should be employed to encourage adherence. Funding is required to develop the evidence base and elucidate the optimal intervention characteristics. PA interventions should form an integral part of the multidisciplinary management of people with affective disorders and our article outlines the evidence and strategies to implement this in practice.

    The Muslims fast every year during the month of Ramadan. A fasting day can last 12-17 h. The effects of fasting on serum lithium levels and the mood changes in patients suffering from bipolar affective disorder during Ramadan are not well studied. We aimed to compare the serum lithium levels, side effects, toxicity and mental state in patients suffering from bipolar affective disorder and on prophylactic lithium therapy before, during and after Ramadan. Sixty-two patients meeting the International Classification of Diseases, Tenth Revision, Research Diagnostic Criteria of bipolar affective disorder receiving lithium treatment for prophylaxis were recruited in a tertiary care teaching hospital in Peshawar, Pakistan. Serum lithium, electrolytes, Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS) were assessed at three points, 1 week before Ramadan, midRamadan and 1 week after Ramadan. The side effects and toxicity were measured by a symptoms and signs checklist. There was no significant difference in mean serum lithium levels at three time points (preRamadan=0.45±0.21, midRamadan=0.51±0.20 and postRamadan=0.44±0.23 milli equivalents/litre, P=0.116). The scores on HDRS and YMRS showed significant decrease during Ramadan (F=34.12, P=0.00, for HDRS and F=15.6, P=0.000 for YMRS). The side effects and toxicity also did not differ significantly at three points. In conclusion, the patients who have stable mental state and lithium levels before Ramadan can be maintained on lithium during Ramadan. Fasting in an average temperature of 28°C for up to 12 h per day did not result in elevated serum lithium levels or more side effects and did not have adverse effects on mental state of patients suffering from bipolar affective disorder.

    1986-01-01

    Platelet [3H]imipramine binding (Bmax) was determined in 67 patients with major affective illness (33 euthymic bipolar, 34 depressed unipolar) and 58 normal control subjects. Bipolar patients had significantly lower Bmax values than did control subjects. The mean Bmax in the unipolar patients was lower than in the control subjects, but the difference was not statistically significant. Dissociation constant (Kd) values did not distinguish patients in either category from control subjects. The significantly lower Bmax in euthymic bipolar patients and the apparent state independence of Bmax in some but not all unipolar patients suggest that platelet imipramine binding may be a trait marker in a subset of affective disorders

    Theory of mind (ToM) is an important social cognitive ability that has been investigated in BPD, with inconsistent findings indicating impaired, comparable, and enhanced ToM in BPD. This study aimed to clarify and extend previous findings by investigating affective and cognitive ToM abilities in youth early in the course of BPD, by including a clinical comparison group of youth with major depressive disorder (MDD). Female participants aged 15-24 years diagnosed with BPD (n = 41) or MDD (n = 37) completed the Reading the Mind in the Eyes Test (RMET) and Happé's Cartoon Task, measures of affective and cognitive dimensions of ToM, respectively. The BPD group performed significantly worse than the MDD group on the affective ToM task, even after controlling for age, intelligence and depressive symptoms. Results for cognitive ToM were not significantly different. Finding of poorer performance on a measure of affective ToM, in BPD youth, relative to youth with MDD early in the course of BPD suggest a developmental failure of sociocognitive abilities needed for mentalising and which are theorised as giving rise to core features of BPD. Future research should employ more naturalistic paradigms to study social cognition and should assess individuals even earlier in the course of BPD. Copyright © 2017. Published by Elsevier B.V.

  11. The centrality of affective instability and identity in Borderline Personality Disorder: Evidence from network analysis

    2017-01-01

    We argue that the series of traits characterizing Borderline Personality Disorder samples do not weigh equally. In this regard, we believe that network approaches employed recently in Personality and Psychopathology research to provide information about the differential relationships among symptoms would be useful to test our claim. To our knowledge, this approach has never been applied to personality disorders. We applied network analysis to the nine Borderline Personality Disorder traits to explore their relationships in two samples drawn from university students and clinical populations (N = 1317 and N = 96, respectively). We used the Fused Graphical Lasso, a technique that allows estimating networks from different populations separately while considering their similarities and differences. Moreover, we examined centrality indices to determine the relative importance of each symptom in each network. The general structure of the two networks was very similar in the two samples, although some differences were detected. Results indicate the centrality of mainly affective instability, identity, and effort to avoid abandonment aspects in Borderline Personality Disorder. Results are consistent with the new DSM Alternative Model for Personality Disorders. We discuss them in terms of implications for therapy. PMID:29040324

New diagnostic criteria are highly needed in this scenario. The main aim of this study was to explore the use of behavioral features as an inclusion criterion for CMD, taking into account the relationship of the patients with physicians, and comparing the results with those from patients affected by organic dystonia (OD. Patients and methods: Patients from the outpatient Movement Disorder Service were assigned to either the CMD or the OD group based on Fahn and Williams criteria. Differences in sociodemographics, disease history, psychopathology, and degree of satisfaction about care received were assessed. Patient–neurologist agreement about the etiological nature of the disorder was also assessed using the k-statistic. A logistic regression analysis estimated the discordance status as a predictor to case/control status. Results: In this study, 31 CMD and 31 OD patients were included. CMD patients showed a longer illness life span, involvement of more body regions, higher comorbidity with anxiety, depression, and borderline personality disorder, as well as higher negative opinions about physicians’ delivering of proper care. Contrary to our expectations, CMD disagreement with neurologists about the etiological nature of the disorder was not statistically significant. Additional analysis showed that having at least one personality disorder was statistically associated with the discordance status. Conclusion: This study suggests that CMD patients show higher conflicting behavior toward physicians. Contrary to our

    Developmental theories of borderline personality disorder (BPD) posit that transactions between child characteristics and adverse environments, especially those in the context of the parent-child relationship, shape and maintain symptoms of the disorder over time. However, very little empirical work has investigated the role of parenting and parent-child transactions that may predict BPD severity over time. We examined maternal and dyadic affective behaviors during a mother-adolescent conflict discussion task as predictors of the course of BPD severity scores across 3 years in a diverse, at-risk sample of girls (N = 74) oversampled for affective instability and their biological mothers. Adolescent girls completed a structured conflict discussion task with their mothers at age 16. Girls' self-reported BPD severity scores were assessed annually from ages 15 to 17. Mother-adolescent interactions were coded using a global rating system of maternal and dyadic affective behaviors. Results from multilevel linear mixed models indicated that positive maternal affective behavior (i.e., supportive/validating behavior, communication skills, autonomy-promoting behavior, and positive affect) and positive dyadic affective behaviors (i.e., satisfaction and positive escalation) were associated with decreases in girls' BPD severity scores over time. Dyadic negative escalation was associated with higher overall levels of BPD severity scores, but negative maternal affective behavior (i.e., negative affect, dominance, conflict, and denial) was not. These findings suggest that the mother-daughter context is an important protective factor in shaping the course of BPD severity scores during adolescence and may be valuable in assessment, intervention, and prevention efforts.

    Although deficits in facial affect processing have been reported in schizophrenia as well as in borderline personality disorder (BPD), these disorders have not yet been directly compared on facial affect labeling. Using degraded stimuli portraying neutral, angry, fearful and angry facial expressions, we hypothesized more errors in labeling negative facial expressions in patients with schizophrenia compared to healthy controls. Patients with BPD were expected to have difficulty in labeling neutral expressions and to display a bias towards a negative attribution when wrongly labeling neutral faces. Patients with schizophrenia (N = 57) and patients with BPD (N = 30) were compared to patients with somatoform disorder (SoD, a psychiatric control group; N = 25) and healthy control participants (N = 41) on facial affect labeling accuracy and type of misattributions. Patients with schizophrenia showed deficits in labeling angry and fearful expressions compared to the healthy control group and patients with BPD showed deficits in labeling neutral expressions compared to the healthy control group. Schizophrenia and BPD patients did not differ significantly from each other when labeling any of the facial expressions. Compared to SoD patients, schizophrenia patients showed deficits on fearful expressions, but BPD did not significantly differ from SoD patients on any of the facial expressions. With respect to the type of misattributions, BPD patients mistook neutral expressions more often for fearful expressions compared to schizophrenia patients and healthy controls, and less often for happy compared to schizophrenia patients. These findings suggest that although schizophrenia and BPD patients demonstrate different as well as similar facial affect labeling deficits, BPD may be associated with a tendency to detect negative affect in neutral expressions.

    Cognitive models have suggested that extreme appraisals of affective states and maladaptive affect regulation strategies are important in the development of bipolar symptomatology. Little is known about the pathway by which these appraisals and behaviours interact in the formation of activated and depressed affective states. This study tested the predictions that (1) ascent behaviours mediate the relationship between positive appraisals of activated mood and activation; and (2) descent behaviours mediate the relationship between negative appraisals of activated mood and depression. A total of 52 individuals with a DSM-IV diagnosis of bipolar I or II disorder (confirmed by structured interview) completed biweekly assessments of affect regulation behaviours and mood for 4 weeks. Positive and negative appraisals of affective states were assessed at baseline through the Hypomanic Attitudes and Positive Prediction Inventory. Multilevel mediation analysis was used to explore the data. Ascent behaviours partially mediated the relationship between positive appraisals of activated mood and activation. Descent behaviours, but not negative appraisals of activated mood, predicted levels of depression indicating the absence of a mediation effect. The results suggest that positive appraisals of activated mood can escalate activation in individuals with bipolar disorder. Such appraisals may be inherently rewarding and reinforcing directly elevating levels of activation, whilst increasing individuals' use of ascent behaviours. The results are consistent with the view that appraisals and behaviours should be targeted during cognitive behavioural therapy for bipolar disorder. It may be beneficial to target positive appraisals of activated mood in cognitive behavioural therapy for mania. Cognitive behavioural therapists may also wish to focus on identifying and targeting individuals' use of ascent behaviours to reduce highly activated states. © 2015 The British Psychological

    This paper intends to analyse seasonal variations of the quality of the water of the Odiel River. This river, together with the Tinto River, drains the Iberian Pyrite Belt (IPB), a region containing an abundance of massive sulphide deposits. Because of mining activity dating back to prehistoric times, these two rivers are heavily contaminated. The Odiel and Tinto Rivers drain into a shared estuary known as the Ria of Huelva. This work studies dissolved contaminant data in water of the Odiel River collected by various organisations, between October 1980 and October 2002, close to the rivers entry into the estuary. Flow data for this location were also obtained. The most abundant metals in the water, in order of abundance, are zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu). Arsenic (As), cadmium (Cd) and lead (Pb) are also present but in much lower quantities. The quality of the river water is linked to precipitation; the maximum sulphate, Fe, Zn, Mn, Cd and Pb concentrations occur during the autumn rains, which dissolve the Fe hydroxysulphates that were precipitated during the summer months. In winter, the intense rains cause an increase in the river flow, producing a dilution of the contaminants and a slight increase in the pH. During spring and summer, the sulphate and metal concentration (except Fe) recover and once again increase. The Fe concentration pattern displays a low value during summer due to increased precipitation of ferric oxyhydroxides. The arsenic concentration displays a different evolution, with maximum values in winter, and minimum in spring and summer as they are strongly adsorbed and/or coprecipitated by the ferric oxyhydroxides. Mn and sulphates are the most conservative species in the water. Relative to sulphate, Mn, Zn and Cd, copper displays greater values in winter and lower ones in summer, probably due to its coprecipitation with hydroxysulphates during the spring and summer months. Cd and Zn also appear to be affected by the same

    Patients with bipolar disorder (BD) have affect recognition deficits. Whether affect recognition deficits constitute a state or trait marker of BD has great etiopathological significance. The current study aims to explore the interrelationships between affect recognition and basic neurocognitive functions for patients with BD across different mood states, using the Diagnostic Analysis of Non-Verbal Accuracy-2, Taiwanese version (DANVA-2-TW) as the index measure for affect recognition. To our knowledge, this is the first study examining affect recognition deficits of BPD across mood states in the Han Chinese population. Twenty-nine manic patients, 16 remitted patients with BD, and 40 control subjects are included in the study. Distinct association patterns between affect recognition and neurocognitive functions are demonstrated for patients with BD and control subjects, implicating alternations in emotion associated neurocognitive processing. Compared to control subjects, manic patients but not remitted subjects perform significantly worse in the recognition of negative emotions as a whole and specifically anger, after adjusting for differences in general intellectual ability and basic neurocognitive functions. Affect recognition deficit may be a relatively independent impairment in BD rather than consequences arising from deficits in other basic neurocognition. The impairments of manic patients in the recognition of negative emotions, specifically anger, may further our understanding of core clinical psychopathology of BD and have implications in treating bipolar patients across distinct mood phases. © 2013 Elsevier B.V.

    The bi-relationships between psychological stress, negative affect and disordered eating has been well studied in western culture, while tri-relationship among them, i.e. how some of those factors influence these bi-relationships, has rarely been studied. However, there has been little related study in the different Chinese culture. This study was conducted to investigate the bi-relationships and tri-relationship between psychological stress, negative affect, and disordered eating attitudes and behaviors in young Chinese women. A total of 245 young Chinese policewomen employed to carry out health and safety checks at the 2010 Shanghai World Expo were recruited in this study. The Chinese version of the Perceived Stress Scale (PSS-10), Beck Depression Inventory Revised (BDI-II), Beck Anxiety Inventory (BAI), and Eating Attitude Test (EAT-26) were administered to all participants. The total scores of PSS-10, BDI-II and BAI were all highly correlated with that of EAT-26. The PSS-10 score significantly correlated with both BDI-II and BAI scores. There was no statistically significant direct effect from perceived stress to disordered eating (-0.012, 95%CI: -.038~0.006, p=0.357), however, the indirect effects from PSS-10 via affect factors were statistically significant, e.g. the estimated mediation effects from PSS to EAT-26 via depression and anxiety were 0.036 (95%CI: 0.022~0.044, peffective interventions and preventative programmes for disordered eating should pay more attention to depression and anxiety among the young Chinese female population.

    The purpose of this study was to examine the potential moderating effect of posttraumatic stress disorder (PTSD) on the emotion-behavior relationship in individuals with bulimia nervosa (BN). A total of 119 women with BN were involved in the study. Participants were divided into 2 groups: those with BN and PTSD (n = 20) and those with BN only (n = 99). Ecological momentary assessment procedures were used for the examination of affect, frequency of bulimic behaviors, and the relationship of affect and bulimic behavior over time. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis I Disorders was conducted for the diagnosis of BN, PTSD, mood disorders, anxiety disorders, and substance use disorders. Mood disorders, anxiety disorders, and substance use disorders functioned as covariates in all analyses. Statistical models showed that those in the PTSD group reported a greater daily mean level of negative affect (NA) and a greater daily frequency of bulimic behaviors than those in the BN-only group. Moderation was found for the association between NA and time in that the PTSD group showed a faster acceleration in NA before purging and faster deceleration in NA after purging. The association between positive affect and time was also moderated by group, indicating that the PTSD group had a faster acceleration in positive affect after purging than the BN-only group. These findings highlight the importance of recognizing PTSD when interpreting the emotion-behavior relationship in individuals with BN. Published by Elsevier Inc.

    Knowledge of emotional dysfunction in patients with avoidant personality disorder (APD) is much needed. The present study examined affect consciousness (AC) in patients with APD compared to borderline personality disorder (BPD). AC, defined as capacity to perceive, reflect on, tolerate, and express emotional experiences, is assumed to be central to structure-building in personality. The study tested the hypotheses that patients with APD have lower general AC and lower AC for pleasant affects compared to BPD. Fifty-nine patients, 26 with APD and 33 with BPD were rated on several aspects of AC using the specialized AC interview. The structured interview SCID-II was applied for diagnostic evaluations. The APD group had significantly lower levels of global AC and conceptual expressivity compared to the BPD group. Among 11 specific affects the APD group had significantly lower AC for interest and contempt. Emotional dysfunction is an important feature of APD and the findings indicate that psychotherapies for APD patients should focus on emotional experiences, aiming to improve emotional awareness, tolerance, and expressivity. The notion of a general avoidance of positive emotions in APD needs further exploration, including a possible dysfunction in the evolutionary based neuro-affective Seeking system. © 2013 The Scandinavian Psychological Associations.

  2. Autism as a developmental disorder in intentional movement and affective engagement

    Full Text Available We review evidence that autistic spectrum disorders have their origin in early, prenatal failure of development in systems that program timing, serial coordination and prospective control of movements and that regulate affective evaluations of experiences. There are effects in early infancy, before medical diagnosis, especially in motor sequencing, selective or exploratory attention, affective expression and intersubjective engagement with parents. These are followed by retardation of cognitive development and language learning in the second or third year, which lead to a diagnosis of ASD. The early signs relate to abnormalities that have been found in brain stem systems and cerebellum in the embryo or early foetal stage, before the cerebral neocortex is functional, and they have clear consequences in infancy when neocortical systems are intensively elaborated. We propose, with evidence of the disturbances of posture, locomotion and prospective motor control in children with autism, as well as facial expression of interest and affect, and attention to other persons’ expressions, that examination of the psychobiology of motor affective disorders, rather than later developing cognitive or linguistic ones, may facilitate early diagnosis. Research in this area may also explain how intense interaction, imitation or ‘expressive art’ therapies, which respond intimately with motor activities, are effective at later stages. Exceptional talents of some autistic people may be acquired compensations for basic problems with expectant self-regulations of movement, attention and emotion.

    We aimed to examine the potential relationship between season of birth (SOB) and clinical characteristics in Korean patients with unipolar non-psychotic major depressive disorder (MDD). Using data from the Clinical Research Center for Depression (CRESCEND) study in South Korea, 891 MDD patients were divided into two groups, those born in spring/summer (n=457) and those born in autumn/winter (n=434). Measurement tools comprising the Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Brief Psychiatric Rating Scale, Scale for Suicidal Ideation, Clinical Global Impression of severity, Social and Occupation Functional Assessment Scale, WHO Quality of Life assessment instrument-abbreviated version, Alcohol Use Disorder Identification Test, and Temperament and Character Inventory were used to evaluate depression, anxiety, overall symptoms, suicidal ideation, global severity, social function, quality of life, drinking, and temperament and character, respectively. Using independent t-tests for continuous variables and χ² tests for discrete variables, the clinical characteristics of the two groups were compared. MDD patients born in spring/summer were on average younger at onset of first depressive episode (t=2.084, p=0.038), had greater loss of concentration (χ²=4.589, p=0.032), and were more self-directed (t=2.256, p=0.025) than those born in autumn/winter. Clinically, there was a trend for the MDD patients born in spring/summer to display the contradictory characteristics of more severe clinical course and less illness burden; this may have been partly due to a paradoxical effect of the 5-HT system.

    Typically, the diagnosis of conversion motor disorder (CMD) is achieved by the exclusion of a wide range of organic illnesses rather than by applying positive criteria. New diagnostic criteria are highly needed in this scenario. The main aim of this study was to explore the use of behavioral features as an inclusion criterion for CMD, taking into account the relationship of the patients with physicians, and comparing the results with those from patients affected by organic dystonia (OD). Patients from the outpatient Movement Disorder Service were assigned to either the CMD or the OD group based on Fahn and Williams criteria. Differences in sociodemographics, disease history, psychopathology, and degree of satisfaction about care received were assessed. Patient-neurologist agreement about the etiological nature of the disorder was also assessed using the k -statistic. A logistic regression analysis estimated the discordance status as a predictor to case/control status. In this study, 31 CMD and 31 OD patients were included. CMD patients showed a longer illness life span, involvement of more body regions, higher comorbidity with anxiety, depression, and borderline personality disorder, as well as higher negative opinions about physicians' delivering of proper care. Contrary to our expectations, CMD disagreement with neurologists about the etiological nature of the disorder was not statistically significant. Additional analysis showed that having at least one personality disorder was statistically associated with the discordance status. This study suggests that CMD patients show higher conflicting behavior toward physicians. Contrary to our expectations, they show awareness of their psychological needs, suggesting a possible lack of recognition of psychological distress in the neurological setting.

    This study evaluates whether the difference in Toronto Alexithymia Scale-20 item (TAS-20) between patients with major depression (MD), panic disorder (PD), eating disorders (ED), and substance use disorders (SUD) and healthy controls persisted after controlling for the severity of anxiety and depression. Thirty-eight patients with MD, 58 with PD, 52 with ED, and 30 with SUD and 78 healthy controls (C) completed the TAS-20, the Hamilton Rating Scale for Anxiety (Ham-A), the Hamilton Rating Scale for Depression (Ham-D). The differences in TAS-20 scores observed between patient groups, regardless of the type of their disorders, and controls disappeared after controlling for the effect of anxiety and depression severity. In contrast, the differences in severity of anxiety and depression between patients and controls were still present, after excluding the effect of alexithymic levels. Our data suggest that alexithymic levels, as measured by the TAS-20, are modulated by the severity of symptoms, supporting the view that alexithymia can represent a state phenomenon in patients with MD, PD, ED and SUD, because the TAS-20 seems overly sensitive to a general distress syndrome, and it is more likely to measure negative affects rather than alexithymia itself.

    Theories of Borderline Personality Disorder (BPD) suggest that interpersonal problems in BPD act as triggers for negative affect and, at the same time, are a possible result of affective dysregulation. Therefore, we assessed the relations between momentary negative affect (hostility, sadness, fear) and interpersonal problems (rejection, disagreement) in a sample of 80 BPD and 51 depressed outpatients at 6 time-points over 28 days. Data were analyzed using multivariate multi-level modeling to separate momentary-, day-, and person-level effects. Results revealed a mutually reinforcing relationship between disagreement and hostility, rejection and hostility, and between rejection and sadness in both groups, at the momentary and day level. The mutual reinforcement between hostility and rejection/disagreement was significantly stronger in the BPD group. Moreover, the link between rejection and sadness was present at all three levels of analysis for the BPD group, while it was localized to the momentary level in the depressed group. PMID:28529826

    Affective Bipolar Disorder (ABD) is observed in all countries of the world with a prevalence fluctuating between 3 and 6.5%. The nature of its clinical manifestations and clinical evolution constitute a diagnostic and therapeutic challenge even for the most experienced clinician. We have analysed by means of NeuroSPECT the neuro functional cortical and subcortical expression of a cohort of 44 eutimic patients with DSM IV criteria compatible with the diagnosis of ABD. The results were expressed in functional 3 dimensional images normalized for volume and compared to a normal data base matched for the age of the patient. Quantitative analyses considered the maximal regional perfusion in each Brodmann area with behavioral significance. The results were expressed in standard deviations with respect to the control population and we considered these findings as a continual variable susceptible to statistical analyses. In the cortex we report the presence of increased perfusion in subregions of areas 8, 9 and 10 of Brodmann (executive area) also in area 7 of Brodmann (posterior parietal lobe). We describe also relative decreased perfusion in areas 24 and 32 (internal frontal lobe), area 25 (affective area), area 21, 22 and 38 (temporal lobe). In subcortical structures we report increased perfusion in thalamus, caudate, and lentiform nucleous with values superior to 3 standard deviations above the normal controls. These findings can constitute neurofunctional markers of ABD that can be used as a clinical diagnostic tool. These findings suggest the participation of cortical/subcortical circuits as the probable etiologic substratum in affective bipolar disorders. Keys: Affective Bipolar Disorders (Au)

    One-year-old Norway spruce (Picea abies (L.) Karst.) seedlings were grown hydroponically in a growth chamber to investigate the effects of low and high nutrient availability (LN; 0.25 mM N and HN; 2.50 mM N) on growth, biomass allocation and chemical composition of needles, stem and roots during the second growing season. Climatic conditions in the growth chamber simulated the mean growing season from May to early October in Flakaliden, northern Sweden. In the latter half of the growing season, biomass allocation changed in response to nutrient availability: increased root growth and decreased shoot growth led to higher root/shoot ratios in LN seedlings than in HN seedlings. At high nutrient availability, total biomass, especially stem biomass, increased, as did total nonstructural carbohydrate and nitrogen contents per seedling. Responses of stem chemistry to nutrient addition differed from those of adult trees of the same provenance. In HN seedlings, concentrations of alpha-cellulose, hemicellulose and lignin decreased in the secondary xylem. Our results illustrate the significance of retranslocation of stored nutrients to support new growth early in the season when root growth and nutrient uptake are still low. We conclude that nutrient availability alters allocation patterns, thereby influencing the success of 2-year-old Norway spruce seedlings at forest planting sites.

    Positive mental health (PMH) is an integral and essential component of health that encompasses emotional, psychological and social well-being. The Keyes' two continua model of mental health and illness posits that mental health status is not merely the absence of mental health problems, and it can be enhanced regardless of a diagnosis of mental illness. The present study hypothesized that mentally ill patients with higher levels of PMH would be associated with better life satisfaction and general functioning. 218 outpatients with affective disorders at a tertiary psychiatric hospital were recruited and administered the multidimensional Positive Mental Health instrument, which was validated and developed in Singapore to measure PMH. Depression and anxiety severity were also assessed. Associations of positive mental health with life satisfaction and general functioning were investigated in linear regression models. PMH scores varied largely within patients with depressive and anxiety disorders but did not differ statistically across the two diagnoses, except for emotional support. PMH was associated with both life satisfaction and general functioning with little evidence of confounding by sociodemographic and clinical status. The cross-sectional design of the study could not examine causal relationships. Findings may be restrictive to treatment-seeking population with specific affective disorders. Our study provides evidence to support the notion that a good mental health state is not simply the absence of a mental disorder. Mentally ill patients can also have high levels of PMH that possibly have a moderating or mediating effect on the relationship between patients' clinical symptoms and life satisfaction or general functioning.

    Disturbed interpersonal relationships and misreading of others' intentions are core symptoms of borderline personality disorder (BPD). Despite these impairments, some studies have found an enhanced theory of mind (ToM) in BPD patients. Taking this into consideration, the current study attempts to further understand these discrepancies by separating ToM into two domains: affective and cognitive. Moreover, the study considered the role of comorbid symptoms of depression in these patients. Subjects were 21 patients with BPD, 23 patients with BPD and comorbid major depressive disorder (MDD), and 25 healthy controls (HC). ToM was measured with the Reading the Mind in the Eyes Test (RMET) and the Faux Pas Task, which assessed the affective and cognitive aspects of ToM, respectively. In addition, all participants were evaluated with the Beck Depression Inventory (BDI). Results showed that in both BPD groups (i.e., BPD without MDD and BPD with MDD) affective ToM scores were higher than in the HC group; however, in the cognitive ToM, the HC group performed better than the both BPD groups. Also, overall the BPD group with MDD had decreased ToM skills. Finally, BPD groups received greater scores on the BDI as compared to the HC group. Copyright © 2017 Elsevier B.V. All rights reserved.

    Bipolar disorder (BD) is a disabling illness that is associated with low quality of life (QoL). This low QoL goes further than mood episodes, which suggests that stable traits, such as affective temperaments, can cause functional impairment. Our study analyses the impact of affective temperaments on the Physical Component Summary (PCS) and Mental Component Summary (MCS) of QoL in euthymic BD patients. A multicentre study was conducted in 180 euthymic BD patients and 95 healthy controls. Firstly, statistical analyses were performed to compare QoL and affective temperaments between the two groups. Secondly, Adaptive Lasso Analysis was carried out to identify the potential confounding variables and select the affective temperaments as potential predictors on the PCS and MCS of QoL in BD patients, as well as the control group. QoL scores in terms of PCS and MCS in BD patients were significantly lower than in healthy individuals. Whereas anxious temperament, anxiety disorder comorbidity, and age were the best predictors of PCS impairment in BD patients, anxious temperament, subclinical depressive symptoms, and age were the best predictors of MCS impairment. Further longitudinal studies with unaffected high-risk relatives are needed to examine the potential interaction between affective temperament and psychopathology. Anxious temperament has an impact on QoL in BD in terms of both the physical component and the mental component. Systematic screening of temperament in BD would give clinicians better knowledge of QoL predictors. Further research should allow more individualized treatment of BD patients based on temperamental factors. Copyright © 2018 Elsevier B.V. All rights reserved.

    Here we demonstrate a capability of method based on the Flicker-Noise Spectroscopy (FNS) in analyzing the manifestation bipolar affective disorder (BAD) in EEG. Generally EEG from BAD patient does not show the visual differences from healthy EEG. Analyzing the behavior of FNS-parameters and the structure of 3D-cross correlators allows to discover the differential characteristics of BAD. The cerebral cortex electric activity of BAD patients have a specific collective dynamics and configuration of the FNS-characteristics in comparison with healthy subjects. (paper)

    Brain-derived neurotrophic factor (BDNF) and the hypothalamic-pituitary-adrenal (HPA) axis are considered to play an important role in the pathophysiology of affective disorders. The aim of the present study was to investigate whether the BDNF Val66Met polymorphism is associated with a familiar risk of affective disorder and whether these genotypes affect whole blood BDNF level and salivary cortisol. In a high-risk study, healthy monozygotic and dizygotic twins with and without a co-twin (high- and low-risk twins, respectively) history of affective disorder were identified through nationwide registers. Familiar predisposition to unipolar and bipolar disorder was not associated with any specific genotype pattern of the BDNF Val66Met polymorphism, not in this sample of 124 val/val, 58 val/met and 8 met/met individuals. However, the combination of having a high familiar risk of affective disorder and the met allele was associated with a higher whole blood BDNF (p=0.02) and a higher evening cortisol level (p=0.01), but not with awakening cortisol. Individuals at high risk of affective disorders and who are carriers of the met allele of the Val66Met polymorphism may present with an enhanced stress response. The presence of a specific genotype alone may not enhance the risk of developing an affective episode. Rather, the altered stress response may be expressed only in combination with other risk variants through interactions with the environment.

    In this study, patients with affective disorders with or without suicide attempts were examined according to whether their disorder was unipolar or bipolar. An analysis was made of their socio-demographic variables, comorbid psychiatric symptoms, and affective temperament dimensions in order to understand the effects of these variables on suicide risk. The study populations consisted of 246 inpatients with affective disorders who had been admitted to the Erenköy Research and Training Hospital for Mental and Neurological Disorders (93 patients with unipolar disorders, 153 with bipolar disorders). The TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto-questionnaire), the Beck Hopelessness Scale (BHS) and the Symptom Checklist-90-Revised (SCL-90-R) psychological symptom screening tests were applied to all patients. In order to determine the affective disorder diagnosis and to identify suicide attempts, a Mini International Neuropsychiatric Interview (MINI) was performed during the first 48 hours of hospitalization. The cyclothymic and anxious temperament dimensions measured using TEMPS-A, somatic symptoms obtained from a symptom checklist, and psychiatric disorders in the family were found to be good indicators of suicide attempts in patients with unipolar disorders in this study. An investigation of predictors of suicide attempts in bipolar patients showed that cyclothymic temperament pattern, paranoid symptoms, evaluated through symptom screening test and having a psychiatric disorder in the family are good predictors of a suicide attempt. The findings are expected to guadiance to preventing suicide in patients with affective disorders. The inclusion in this study of patients with different index episodes of illness, including manic, depressive and mixed periods, can be accepted as a significant limitation of this study.

    Water requirements and metabolism and some physiological and blood characteristics were studied in dry non-pregnant Barki and Rahmani ewes and in Baladi goats during spring, summer and winter seasons. The Rahmani sheep showed greater thermal discomfort than the Barki during the summer season. Pregnancy was associated with a significant increase in body weight and a decline in PCV and total serum protein, and these changes were greater in goats than in sheep. They were accompanied by significant increases in TBW and WTR. All these changes were more pronounced during late pregnancy than during mid-pregnancy, although the effect of stage of pregnancy on TBW did not occur in the Barki ewes. The pregnancy induced changes in total protein and WTR were greater in spring, while those in TBW were greater in winter. The above parameters also showed similar changes during lactation (particularly during early lactation), but lactating animals showed a decrease instead of an increase in body weight. Goats showed greater reductions in body weight, PCV and water t 1/2 and greater increases in WTR than sheep during the spring season. Withdrawal of drinking water for four days caused a reduction in body weight, blood glucose and plasma T 3 and T 4 , and an increase in PCV, total serum protein and plasma osmolality. Plasma aldosterone increased slightly during dehydration but increased markedly during the rehydration period, particularly in the Rahmani sheep during the summer season. The above parameters changed similarly when the animals were starved for four days (feed but not water was withheld), but total serum protein showed a decrease instead of an increase. Changes during dehydration were more pronounced in summer, while those during starvation were greater in winter. 32 refs, 4 figs, 2 tabs

    2008-12-01

    In the present review, we examine one of the critical issues that have been raised about evidence-based treatments and their portability to real-world clinical settings: namely, the presence of comorbidity in the participants who have been treated in these studies and whether the presence of comorbidity predicts or moderates treatment outcomes. In doing so, we examine treatment outcomes for the four most commonly occurring childhood psychiatric disorders: Anxiety disorders, affective disorders, attention deficit/hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD)/conduct disorder (CD). For each of these disorders, we first review briefly the prevalence of comorbidity in epidemiological and clinical samples and then highlight the evidence-based treatments for these disorders. We next determine the effects of comorbidity on treatment outcomes for these disorders. For the most part, comorbidity in the treated samples is the rule, not the exception. However, the majority of studies have not explored whether comorbidity predicts or moderates treatment outcomes. For the not insignificant number of studies that have examined this issue, comorbidity has not been found to affect treatment outcomes. Notable exceptions are highlighted and recommendations for future research are presented.

    Palacios, C.; Abecia, J. A.

    2015-05-01

    A total number of 48,088 artificial inseminations (AIs) have been controlled during seven consecutive years in 79 dairy sheep Spanish farms (41° N). Mean, maximum and minimum ambient temperatures ( Ts), temperature amplitude (TA), mean relative humidity (RH), mean solar radiation (SR) and total rainfall of each insemination day and 15 days later were recorded. Temperature-humidity index (THI) and effective temperature (ET) have been calculated. A binary logistic regression model to estimate the risk of not getting pregnant compared to getting pregnant, through the odds ratio (OR), was performed. Successful winter inseminations were carried out under higher SR ( P 1 (maximum T, ET and rainfall on AI day, and ET and rainfall on day 15), and two variables presented OR AI day and maximum T on day 15). However, the effect of meteorological factors affected fertility in opposite ways, so T becomes a protective or risk factor on fertility depending on season. In conclusion, the percentage of pregnancy after AI in sheep is significantly affected by meteorological variables in a seasonal-dependent manner, so the parameters such as temperature reverse their effects in the hot or cold seasons. A forecast of the meteorological conditions could be a useful tool when AI dates are being scheduled.

    Toxicologists must ensure that clinical risk-to-benefit analysis should be made both for genders and age groups, with any treatment. Puberty concerns physiological changes leading to organism's maturation. Pubertal growth disorders are increasing in last decades: besides causing physical and psychological distress, they may signal underlying endocrine-metabolic abnormalities with serious health consequences later on. Therapeutic approaches for some health conditions in childhood and adolescence are considered. The authors discuss how some diseases and treatments can impact pubertal growth. The authors look at particular immunological disorders such as asthma and how both the disease and treatment affects pubertal growth. They also discuss how the provision of available data can help to assess the dose-response of the drug, in these cases, and minimize the chance of side effects. The authors also discuss pediatric inflammatory bowel disease and how both the disease and treatment can mitigate the growth delay. Last, but not least, the authors discuss how the effects of the drugs used in the treatment of psychiatric disorders may accentuate endocrine issues in juvenile patients. Hyperprolactinemia induction by some antipsychotics is highlighted as an example. Appropriate risk-benefit analysis of drugs prescribed during childhood and adolescence and intended to be used in the long term is required. Furthermore, future treatment strategies and safer compounds development should be supported by the knowledge of mechanisms underlying adverse side effects in pubertal growth and development.

  6. Spiritual beliefs in bipolar affective disorder: their relevance for illness management.

    There has been growing interest in investigating religion as a relevant element in illness outcome. Having religious beliefs has been shown repeatedly to be associated with lessened rates of depression. Most of the limited published research has been restricted to elderly samples. Religious coping is thought to play a key role in religion's effects. Strangely, psychiatric research has neglected this area. A questionnaire covering religious, spiritual and philosophical beliefs and religious practice was given to a sample of patients with bipolar affective disorder in remission. Most patients often held strong religious or spiritual beliefs (78%) and practised their religion frequently (81.5%). Most saw a direct link between their beliefs and the management of their illness. Many used religious coping, and often religio-spiritual beliefs and practice put them in conflict with illness models (24%) and advice (19%) used by their medical advisors. This was a cross-sectional design without a control group and thus it is not possible to determine causal associations from the data set. Religio-spiritual ideas are of great salience to many patients with bipolar disorder and shape the ways in which they think about their illness. Many reported experiencing significant paradigm conflict in understanding and managing their illness between medical and their spiritual advisors. These data suggest that the whole area of religion and spirituality is directly relevant to people living with a chronic psychiatric illness and should be firmly on the discussion agenda of clinicians working with patients with bipolar disorder.

    Full Text Available Objective: Early detection of children who are at risk for speech and language impairment and those at early stages of delay is crucial for provision of early intervention services. However, unfortunately in Iran, this disorder is not identified or referred for proper treatment and rehabilitation at early critical stages. Materials & Methods: This study was carried out in two phases. The first phase which was qualitative in nature was meant to identify all potentially affective factors through literature review as well as by acquiring the viewpoints of experts and families on this issue. Twelve experts and 9 parents of children with speech and language disorders participated in semi-structured in-depth interviews, thereby completing the first draft of potentially affective factors compiled through literature review. The completed list of factors finally led to the design of a questionnaire for identifying “factors affecting late referral in childhood speech and language impairment”. The questionnaire was approved for face and content validity. The cronbach’s alpha was determined to be 0.81. Two groups of parents were asked to complete the questionnaire: the parents of children who had attended speech and language clinics located on the west and central regions of Tehran city, after their child was 3 years old and those who had attended before their child was 3 years old, as the case and control group, respectively. Results: According to the results, among the seven factors which showed significant difference between the two groups of children before definite diagnosis of speech and language disorders was arrived for the child, 3 factors were related to the type of guidance and consultation received by the family from physicians, 2 factors were related to parents’ lack of awareness and knowledge, and 2 factors were related to the screening services received. All six factors showing significant difference between the two groups after

    Impaired interpersonal, social, and occupational functioning is very often observed in patients with bipolar disorder, not only at the acute stages of the illness but in remission as well. This finding raises the question of multiple factors that might affect psychosocial functioning in bipolar patients, such as residual subsyndromal symptoms and neuropsychological deficits. Social cognition impairment, especially impaired Theory of Mind (ToM), might also play an important role in bipolar patients' every-day functioning, similarly to what was found in patients with schizophrenia. The present study aimed to investigate the potential effect of clinical and cognitive factors on the psychosocial functioning of patients with bipolar disorder during remission, assessing ToM along with a broad range of basic cognitive functions. Forty-nine patients with bipolar disorder type I in remission and 53 healthy participants were assessed in general intelligence, working memory, attention, speed processing, verbal learning and memory, and executive functions using a comprehensive battery of neuropsychological tests. The Faux Pas Recognition Test was used to assess ToM. The two groups were matched for gender, age and education level. The Hamilton Rating Scale for Depression (HDRS), the Young Mania Rating Scale (YMRS), and the Brief Psychiatric Rating Scale (BPRS) were also administered to the patients. Every-day functioning was assessed with the Global Assessment of Functioning (GAF). In order to examine the contribution of many factors in psychosocial functioning, we used hierarchical multiple regression analysis. Bipolar patients presented significant impairment compared to healthy participants in all the basic cognitive functions tested with the exception of verbal memory. Moreover, patients had significant poorer performance than healthy controls in overall psyand cognitive ToM but not in affective ToM as measured by Faux Pas. Psychosocial functioning in patient group was

    Full Text Available Background. Several studies have found that patients with affective-/anxiety-/stress-related syndromes present overlapping features such as cooccurrence within families and individuals and response to the same type of pharmacological treatment, suggesting that these syndromes share pathogenetic mechanisms. The term affective spectrum disorder (AfSD has been suggested, emphasizing these commonalities. The expectancy rate, sociodemographic characteristics, and global level of functioning in AfSD has hitherto not been studied neglected. Material and Method. Out of 180 consecutive patients 94 were included after clinical investigations and ICD-10 diagnostics. Further investigations included well-known self-evaluation instruments assessing psychiatric symptoms, personality disorders, psychosocial stress, adaptation, quality of life, and global level of functioning. A neuropsychological screening was also included. Results. The patients were young, had many young children, were well educated, and had about expected (normal distribution of intelligence. Sixty-one percent were identified as belonging to the group of AfSD. Conclusion. The study identifies a large group of patients that presents much suffering and failure of functioning. This group is shared between the levels of medical care, between primary care and psychiatry. The term AfSD facilitates identification of patient groups that share common traits and identifies individuals clinically, besides the referred patients, in need of psychiatric interventions.

    Full Text Available In the current study, we aimed to investigate the impact of childhood trauma on suicidal behaviour phenotypes in a group of patients with diagnosed affective disorder (unipolar or bipolar affective disorder.Patients with and without a history of childhood abuse, measured by Childhood Trauma Questionnaire (CTQ, were assessed to explore risks for suicidal behaviour (including suicide attempt, self-harm and non-suicidal self-injury. The tested sample consisted of 258 patients (111 males and 147 females, in-patients and out-patients at the Department of Psychiatry and Psychotherapy, Medical University of Vienna and University Hospital Tulln, Lower Austria. Psychiatric diagnoses were derived from the SCAN (Schedules for Clinical Assessment in Neuropsychiatry interview. In addition, patients were administered the Lifetime Parasuicidal Count (LPC, Suicidal Behaviour Questionnaire (SBQ-R, and Viennese Suicide Risk Assessment Scale (VISURIAS questionnaires.In contrast to male suicide attempters, female suicide attempters showed both significantly higher total CTQ scores (p<0.001, and higher CTQ subscores (emotional, physical and sexual abuse, as well as emotional and physical neglect in comparison to the non-suicidal control group. Besides, females with a history of self-harming behaviour (including suicidal intention and Non-Suicidal-Self Injury (NSSI had significantly higher CTQ total scores (p<0.001 than the control group.These findings suggest gender differences in suicidal behaviour after being exposed to childhood trauma.

    The individual enabling and support (IES) model was effective in gaining competitive employment for people with affective disorders compared with traditional vocational rehabilitation (TVR) services in a randomized controlled trial in a Swedish setting. The object of this study is to perform a cost-effectiveness analysis of IES comparing to TVR. We considered the costs of intervention and productivity gain due to increased competitive employment. We estimated quality of life using EuroQol 5 Dimension (EQ-5D) and Manchester Short Assessment of Quality of Life (MANSA) scale. EQ-5D was translated into quality-adjusted life-years (QALY), using the UK, Danish, and Swedish tariffs. We performed the analysis from a societal perspective with a one-year timeframe. The cost of IES was €7247 lower per person per year (2014 prices) compared to TVR. There were no significant differences in QALY improvement within or between groups. However, quality of life measured by the MANSA scale significantly improved over the study period in IES. Besides the small sample size, details on the intervention costs for both IES and TVR group were unavailable and had to be obtained from external sources. Implementation of IES for people with affective disorders is most likely cost-saving and is potentially even dominating TVR, although a larger trial is required to establish this.

    Although many studies have explored the effect of current affective episodes on insight into bipolar disorder, the potential interaction between current mood state and previous affective episodes has not been consistently investigated. To explore the influence of dominant polarity, number of previous affective episodes and current affective state on insight in bipolar disorder patients in euthymia or mania. A total of 101 patients with bipolar disorder were recruited for the study, including 58 patients in euthymia (30 with no defined predominant polarity and 28 with manic predominant polarity) and 43 in mania (26 with no defined predominant polarity and 17 with manic predominant polarity). Patients underwent a clinical assessment and insight was evaluated through the Insight Scale for Affective Disorders. Bipolar disorder patients in mania had worse insight than those in euthymia, with no effect of dominant polarity. In addition, positive psychotic symptoms showed a significant effect on insight and its inclusion as a covariate eliminated differences related to mood state. Finally, the number of previous manic or depressive episodes did not correlate with insight level. Mania is a predictor of loss of insight into bipolar disorder. However, it is possible that its contribution is linked to the more frequent presence of psychotic symptoms in this state. Dominant polarity and number/type of previous affective episodes have a limited impact on insight.

    Full Text Available BACKGROUND Mental and behavioural disorders have a large impact on individuals, family and communities. There is a paucity of studies on burden and cost of illness of Bipolar Affective Disorder both internationally and in India. Such studies are important for clinical management and policy decisions. Aim of the study - The aim of the present study is to assess the magnitude of the cost of illness and family burden of Bipolar Affective Disorder and Schizophrenia and to find out the difference in the burden of the caregivers for both the groups. MATERIALS AND METHODS The study was conducted in the outpatient department of Institute of Mental Health, Chennai. Sixty patients in each group were included by stratified sampling. Caregivers living with patients for atleast one year are included in the study, and those with any comorbid illness, were excluded from the study. ICD -10 diagnostic and research criteria were used for diagnosis of BPAD and Schizophrenia, Questionnaire for Assessment of Cost of Illness was used to assess cost of illness and Family Burden Interview Schedule was used to assess burden of caregivers. RESULTS Schizophrenia patients are mostly from urban, nuclear family. The illness characters & sociodemographic profile of caregivers are comparable. Lifetime costs and loss of income over lifetime was more in schizophrenia. Loss of income in the past year was similar. The burden was comparable for caregivers of both groups in disruption of family routine, interaction with family members, effect on mental health. CONCLUSION Burden of both diseases were comparable except schizophrenics experience more financial burden.

    Impulse control disorders (ICDs) in Parkinson's disease (PD) are considered dopaminergic treatment side effects. Cognitive and affective factors may increase the risk of ICD in PD. The aim is to investigate risky decision-making and associated cognitive processes in PD patients with ICDs within a four-stage conceptual framework. Relationship between ICDs and affective factors was explored. Thirteen PD patients with ICD (ICD+), 12 PD patients without ICD (ICD-), and 17 healthy controls were recruited. Overall risky decision-making and negative feedback effect were examined with the Balloon Analogue Risk Task (BART). A cognitive battery dissected decision-making processes according to the four-stage conceptual framework. Affective and motivational factors were measured. ANOVA showed no effect of group on overall risky decision-making. However, there was a group × feedback interaction [F (2, 39) = 3.31, p = 0.047]. ICD+, unlike ICD- and healthy controls, failed to reduce risky behaviour following negative feedback. A main effect of group was found for anxiety and depression [F(2, 38) = 8.31, p = 0.001], with higher symptoms in ICD+ vs. healthy controls. Groups did not differ in cognitive outcomes or affective and motivational metrics. ICD+ may show relatively preserved cognitive function, but reduced sensitivity to negative feedback during risky decision-making and higher symptoms of depression and anxiety.

    Full Text Available Conventional treatments for mood disorders primarily focus on reducing negative affect, but little on enhancing positive affect. Loving-kindness meditation (LKM is a traditional meditation practice directly oriented toward enhancing unconditional and positive emotional states of kindness towards oneself and others. We report here two independent and uncontrolled studies carried out at different centers, one in Boston, USA (n = 10, and one in Frankfurt, Germany (n = 8, to examine the potential therapeutic utility of a brief LKM group intervention for symptoms of dysthymia and depression. Results at both centers suggest that LKM was associated with large-sized effects on self-reported symptoms of depression (d = 3.33 and 1.90, negative affect (d = 1.98 and 0.92, and positive affect (d = 1.63 and 0.94. Large effects were also found for clinician-reported changes in depression, rumination and specific positive emotions, and moderate effects for changes in adaptive emotion regulation strategies. The qualitative data analyses provide additional support for the potential clinical utility of the intervention. This proof-of-concept evaluation of LKM as a clinical strategy warrants further investigation.

    Depression goes often unrecognised and untreated in non-psychiatric medical settings. Screening has recently gained acceptance as a first step towards improving depression recognition and management. The Primary Care Screener for Affective Disorders (PC-SAD) is a self-administered questionnaire to screen for Major Depressive Disorder (MDD) and Dysthymic Disorder (Dys) which has a sophisticated scoring algorithm that confers several advantages. This study tested its performance against a 'gold standard' diagnostic interview in primary care. A total of 416 adults attending 13 urban general internal medicine primary care practices completed the PC-SAD. Of 409 who returned a valid PC-SAD, all those scoring positive (N=151) and a random sample (N=106) of those scoring negative were selected for a 3-month telephone follow-up assessment including the administration of the Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID-I) by a psychiatrist who was masked to PC-SAD results. Most selected patients (N=212) took part in the follow-up assessment. After adjustment for partial verification bias the sensitivity, specificity, positive and negative predictive value for MDD were 90%, 83%, 51%, and 98%. For Dys, the corresponding figures were 78%, 79%, 8%, and 88%. While some study limitations suggest caution in interpreting our results, this study corroborated the diagnostic validity of the PC-SAD, although the low PPV may limit its usefulness with regard to Dys. Given its good psychometric properties and the short average administration time, the PC-SAD might be the screening instrument of choice in settings where the technology for computer automated scoring is available.

    Full Text Available Genetic variation and early adverse environmental events work together to increase risk for schizophrenia. γ-aminobutyric acid (GABA, the major inhibitory neurotransmitter in adult mammalian brain, plays a major role in normal brain development, and has been strongly implicated in the pathobiology of schizophrenia. GABA synthesis is controlled by two glutamic acid decarboxylase (GAD genes, GAD1 and GAD2, both of which produce a number of alternative transcripts. Genetic variants in the GAD1 gene are associated with increased risk for schizophrenia, and reduced expression of its major transcript in the human dorsolateral prefrontal cortex (DLPFC. No consistent changes in GAD2 expression have been found in brains from patients with schizophrenia. In this work, with the use of RNA sequencing and PCR technologies, we confirmed and tracked the expression of an alternative truncated transcript of GAD2 (ENST00000428517 in human control DLPFC homogenates across lifespan besides the well-known full length transcript of GAD2. In addition, using quantitative RT-PCR, expression of GAD2 full length and truncated transcripts were measured in the DLPFC of patients with schizophrenia, bipolar disorder and major depression. The expression of GAD2 full length transcript is decreased in the DLPFC of schizophrenia and bipolar disorder patients, while GAD2 truncated transcript is increased in bipolar disorder patients but decreased in schizophrenia patients. Moreover, the patients with schizophrenia with completed suicide or positive nicotine exposure showed significantly higher expression of GAD2 full length transcript. Alternative transcripts of GAD2 may be important in the growth and development of GABA-synthesizing neurons as well as abnormal GABA signaling in the DLPFC of patients with schizophrenia and affective disorders.

    Intraoral disease is a common occurrence in patients with eating disorders, particularly dental erosion, which frequently becomes severe and may hinder daily life. The severity varies from patient to patient. Understanding the underlying mechanisms may help prevent dental erosion in these patients. Accordingly, we investigated the relationship between the severity of erosion and the behavior of patients with eating disorders, with a focus on daily diet and vomiting behavior. A total 71 female eating disorder outpatients from the Clinical Center of Psychosomatic Dentistry of Nippon Dental University Hospital and the Psychosomatic Internal Medicine Department of Kudanzaka Hospital or who were hospitalized at Hasegawa Hospital were enrolled. Dental erosion severity and location were determined by oral examination. Patients who induced vomiting were queried on their behavior during vomiting and on routine diet habits. Patients with dental erosion were further divided into mild and severe groups based on the lesion severity and the groups compared. Dental erosion was observed in 43 of 50 subjects who induced vomiting. Dental erosion was most frequent on the palatal side of the anterior maxillary teeth, occurring in 81.3% of the subjects. There were significant differences observed between the mild and severe groups according to post-vomiting oral hygiene. Significantly more subjects in the mild group consumed large amounts of water before vomiting, and significantly more subjects in the severe group routinely consumed carbonated beverages or sweetened food. While self-induced vomiting is the main cause of dental erosion in eating disorder patients, the erosion severity may be affected by behavior when inducing vomiting or by routine consumption of certain foods and beverages. Addressing these factors may help prevent severe dental erosion in patients who chronically induce vomiting.

    Although prescribed exercise has been found to improve affect and reduce levels of depression, we do not know how self-initiated everyday physical activity influences levels of positive affect (PA) and negative affect (NA) in depressed persons. Fifty-three individuals diagnosed with Major Depressive Disorder (MDD) and 53 never-depressed controls participated in a seven-day experience sampling study. Participants were prompted randomly eight times per day and answered questions about their physical activity and affective state. Over the week, the two groups of participants did not differ in average level of physical activity. As expected, participants with MDD reported lower average PA and higher average NA than did never-depressed controls. Both participants with MDD and controls reported higher levels of PA at prompts after physical activity than at prompts after inactive periods; moreover, for both groups of participants, PA increased from a prompt after an inactive period to a subsequent prompt at which activity was reported. Depressed participants in particular showed a dose-response effect of physical activity on affect: longer duration and/or higher intensity of physical activity increased their PA significantly more than did short duration and/or lower intensity physical activity. Physical activity did not influence NA in either group. In contrast to previous treatment studies that examined the effects of prescribed structured exercise, this investigation showed that self-initiated physical activity influences PA. These findings also underscore the importance of distinguishing between PA and NA to gain a more comprehensive understanding of the effects of physical activity on affect in MDD.

    Changes in land-use and land management can have biogeochemical and biophysical effects on local and global climate. While managed ecosystems provide known food and fiber benefits, their influence on climate is less well quantified. In the southeastern United States, there are numerous types of intensely managed ecosystems but pine plantations and switchgrass fields represent two biogeochemical and biophysical extremes; a tall, low albedo forest with trees harvested after multiple decades vs. a short, higher albedo C4 grass field that is harvested annually. Despite the wide spread use of these ecosystems for timber and bioenergy, a quantitative, empirical evaluation of the net influence of these ecosystems on climate is lacking because it requires measuring both the greenhouse gas and energy balance of the ecosystems while controlling for the background weather and soil environment. To address this need, we established a pair of eddy flux towers in these ecosystems that are co-located (1.5 km apart) in Central Virginia and measured the radiative energy, non-radiative energy and carbon fluxes, along with associated biometeorology variables; the paired site has run since April 2016. During the first 1.5 years (two growing seasons), we found strong seasonality in the difference in surface temperature between the two ecosystems. In the growing seasons, both sites had similar surface temperature despite higher net radiation in pine. Following harvest of the switchgrass in September, the switchgrass temperatures increased relative to pine. In the winter, the pine ecosystem was warmer. We evaluate the drivers of these intra-annual dynamics and compare the climate influence of these biophysical differences to the differences in carbon fluxes between the sites using a suite of established climate regulation services metrics. Overall, our results show tradeoffs exist between the biogeochemical and biophysical climate services in managed ecosystems in the southeastern United

    Transdiagnostic psychotherapies are designed to apply the same underlying treatment principles across a set of psychiatric disorders, without significant tailoring to specific diagnoses. Several transdiagnostic psychotherapy protocols have been developed recently, each of which has its own strengths and weaknesses. One promising treatment is Transdiagnostic Behaviour Therapy (TBT), in that it is one of the few transdiagnostic treatments to date shown to be effective in patients with depressive and anxiety disorders. However, TBT has only been investigated via individual psychotherapy. The present study investigated the effectiveness of a group protocol for TBT, compared with disorder-specific group psychotherapies, in a naturalistic setting. 109 participants with various diagnoses of affective disorders completed either group TBT (n = 37) or a disorder-specific group psychotherapy (n = 72). Measures included assessments of psychiatric symptomatology and transdiagnostic impairment at baseline and post-treatment. Overall, participants in the TBT group demonstrated significant improvements across all measures. When compared with disorder-specific groups, no statistical differences were observed between groups across symptoms; however, participants in the TBT group demonstrated roughly twice the treatment effect sizes in transdiagnostic impairment compared with participants in the disorder-specific groups. In addition, when participants from the most well-represented diagnosis and disorder-specific treatment (social anxiety disorder) were investigated separately, participants in the TBT group demonstrated significantly larger improvements in comorbid depressive symptoms than participants in the disorder-specific treatment. Pending replication and additional comparison studies, group TBT may provide an effective group treatment option for patients with affective disorders.

    Thought-action fusion (TAF) is a cognitive bias presumed to underlie the development of obsessional problems (i.e. obsessive-compulsive disorder; OCD). Previous studies have found that TAF is related to not only OCD, but also to other anxiety disorders. In the present study we compared levels of TAF in OCD patients and in patients with other anxiety disorders, depression, and healthy controls to examine whether TAF is characteristic of individuals with emotional distress in general, as opposed to anxiety disorders per se. We also examined whether negative affect (i.e. anxiety and depression) mediates the relationship between OCD and TAF. Results indicated that OCD patients were characterized by higher scores on likelihood-self and likelihood-other TAF, but that this difference was predominately due to differences in negative affect. These findings support a model in which negative affect mediates the relationship between OCD and TAF.

    The correlation between the affective disorders and the almost ubiquitous pathological oxidative stress can be described in a multifactorial way, as an important mechanism of central nervous system impairment. Whether the obvious changes which occur in oxidative balance of the affective disorders are a part of the constitutive mechanism or a collateral effect yet remains as an interesting question. However it is now clear that oxidative stress is a component of these disorders, being characterized by different aspects in a disease-dependent manner. Still, there are a lot of controversies regarding the relevance of the oxidative stress status in most of the affective disorders and despite the fact that most of the studies are showing that the affective disorders development can be correlated to increased oxidative levels, there are various studies stating that oxidative stress is not linked with the mood changing tendencies. Thus, in this minireview we decided to describe the way in which oxidative stress is involved in the affective disorders development, by focusing on the main oxidative stress markers that could be used mechanistically and therapeutically in these deficiencies, the genetic perspectives, some antioxidant approaches, and the relevance of some animal models studies in this context.

From the registers, large population based cohorts were identified...... and followed over several decades. Survival analysis techniques were applied to identify risk factors and mortality rates. The results demonstrated an overlap in risk factors for schizophrenia and bipolar affective disorder. Excess mortality (compared to persons never admitted with a psychiatric disorder......), and environmental factors act (or interact) with this predisposition. However, large differences in gender distribution and age at onset are present, and differences and similarities between the disorders should be further examined before the Kraepelinian dichotomization can be disregarded....

Secondary objectives included gathering data on longitudinal mood trajectories and assessing patient acceptance of mood monitoring. Methods: Inpatients with a primary mood or anxiety disorder were recruited predischarge. Assessment at intake included demographic information, the Life Events Checklist, and the Childhood Trauma Questionnaire. Participants telephonically completed the Altman Self-Rating Mania Scale (ASRM and Quick Inventory of Depressive Symptomatology (QIDS, weekly, for 26 weeks. Units of alcohol consumed and life events were recorded. Semi-structured interviews were conducted midway through the mood monitoring protocol. Results: Of the 61 eligible participants (77% female; mean age =35.3 years, 28 completed 26 weeks of telephonic mood monitoring. Thirty-three participants (54.1% withdrew prematurely or were lost to follow-up. Males were more likely to terminate study participation prematurely. Despite the significant decline in depression scores over 26 weeks, participants endorsed persistent mild-to-moderate depressive symptoms. Statistically, participants who were married/in a relationship had higher mean depression scores throughout the study compared to participants who were single. Throughout the study, ASRM scores were not indicative of significant mania. Suicidality (as measured by QIDS item 12 was highest at Week 3 and Week 12 postdischarge for those who completed 26 weeks of monitoring. Conclusion: Despite the high attrition rate, interepisodal telephonic mood monitoring was deemed to be feasible and it can provide useful

    Etiological models propose that a biological vulnerability to emotional reactivity plays an important role in the development of borderline personality disorder (BPD). However, the physiological and phenomenological components of emotional reactivity that predict the course of BPD symptoms in adolescence are poorly understood. This prospective study examines pupillary and affective responses to maternal feedback as predictors of BPD symptom development in adolescent girls over 18 months. Fifty-seven 16-year-old girls completed a laboratory task in which they heard recorded clips of their own mothers making critical or praising statements about them, as well as neutral statements that did not pertain to them. Changes in girls' pupil dilation and subjective affect were assessed throughout the task. The results demonstrated that greater pupillary response to maternal criticism predicted increases in BPD symptoms over time. In addition, greater pupillary and positive affective responses to maternal praise were associated with higher BPD symptoms at age 16 and faster decreases in BPD symptoms over time, but only among girls who heard clips that were rated by independent observers as less praising. The results suggest that emotional reactivity can serve as either a risk or a protective factor depending on context, with differential effects of reactivity to criticism versus praise.

    Full Text Available Current theories suggest that the brain is the sole source of mental illness. However, affective disorders, and major depressive disorder (MDD in particular, may be better conceptualized as brain-body disorders that involve peripheral systems as well. This perspective emphasizes the embodied, multifaceted physiology of well-being, and suggests that afferent signals from the body may contribute to cognitive and emotional states. In this review, we focus on evidence from preclinical and clinical studies suggesting that afferent thermosensory signals contribute to well-being and depression. Although thermoregulatory systems have traditionally been conceptualized as serving primarily homeostatic functions, increasing evidence suggests neural pathways responsible for regulating body temperature may be linked more closely with emotional states than previously recognized, an affective warmth hypothesis. Human studies indicate that increasing physical warmth activates brain circuits associated with cognitive and affective functions, promotes interpersonal warmth and prosocial behaviour, and has antidepressant effects. Consistent with these effects, preclinical studies in rodents demonstrate that physical warmth activates brain serotonergic neurons implicated in antidepressant-like effects. Together, these studies suggest that 1 thermosensory pathways interact with brain systems that control affective function, 2 these pathways are dysregulated in affective disorders, and 3 activating warm thermosensory pathways promotes a sense of well-being and has therapeutic potential in the treatment of affective disorders.

    Field trial was conducted at two locations of the semi-arid region of Morocco with an objective of estimating the N balance for the applied urea to wheat under two different agroecological zones. N-15 labelled urea was applied in microplots (1 m x 1 m) at tillering stage at rates of 0,40,80, and 120 kg/ha. Soil and plant samples were analyzed for N-15 excess. An average of 45% increase in grain yield of wheat was due to fertilization with 60 kg N/ha. Recovery of N-15 labelled N ranged between 28.8 and 45.1% for the rate of 40 kg N/ha. Results suggested that efficiency of the applied fertilizer is governed by seasonal rainfall and soil properties

    Electroconvulsive therapy (ECT) is the most effective treatment for severe episodes of mood disorders. Temporary memory loss is a common side-effect, but ongoing discussions exist regarding potential long-term adverse cognitive outcomes. Only a few studies have examined the frequency of dementia in patients after ECT. The aim of this study was to examine the association between ECT and risk of subsequent dementia in patients with a first-time hospital diagnosis of affective disorder. We did a cohort study of patients aged 10 years and older in Denmark with a first-time hospital contact for an affective disorder from Jan 1, 2005, through Dec 31, 2015, identified in the Danish National Patient Registry with ICD-10 codes F30.0 to F39.9. From the registry we retrieved information on all ECTs registered for patients and followed up patients for incidental dementia (defined by hospital discharge diagnoses or acetylcholinesterase inhibitor use) until Oct 31, 2016. We examined the association between ECT and dementia using Cox regression analyses with multiple adjustments and propensity-score matching on sociodemographic and clinical variables. Of 168 015 patients included in the study, 5901 (3·5%) patients had at least one ECT. During the median follow-up of 4·9 years (IQR 2·4-7·8) and 872 874 person years, the number of patients who developed dementia was 111 (0·1%) of 99 045 patients aged 10-49 years, 965 (2·7%) of 35 945 aged 50-69 years, and 4128 (12·5%) of 33 025 aged 70-108 years. 217 (3·6%) of the 5901 patients treated with ECT developed dementia, whereas of 162 114 patients not treated with ECT 4987 (3·1%) developed dementia. The corresponding incidences were 70·4 cases per 10 000 person-years (95% CI 61·6-80·5) and 59·2 per 10 000 person-years (57·6-60·8). In patients younger than 50 years and 50-69 years, ECT was not associated with a risk of dementia compared with age-matched patients who were not given ECT (age-adjusted hazard

    Trace metals (Cd, U, Co, Ni, Cu, Ba, Fe, Mn), total organic carbon (TOC) and C and N stable isotope signatures (δ 13C and δ 15N) were determined in short sediments cores from the inner and outer shelf off Concepción, Chile (˜36°S). The objectives were to establish the effect of environmental conditions on trace metal distributions at two shelf sites, one affected by seasonal oxygenation and the other by permanent low oxygen conditions due to the presence of the oxygen minimum zone (OMZ). We evaluate trace metals as proxies of past changes in primary productivity and the bottom water oxygen regime. Concentrations of pore water sulfides and NH4+ were also measured as indicators of the main diagenetic pathways at each site. Our results for the inner shelf (seasonal suboxia) suggest that the oxidative state of the sediments responds to seasonal pulses of organic matter and that seasonal oxygenation develops during high and low primary productivity in the water column. Here, positive fluxes (to the water column) estimated from pore water concentrations of several elements were observed (Ba, Co, Ni, Fe and Mn). The less reduced environment at this site produces authigenic enrichment of Cu associated with the formation of oxides in the oxic surface sediment layer, and the reduction of U within deeper sediment sections occur consistently with negative estimated pore water fluxes. In the outer shelf sediments (permanent suboxia, OMZ site), negative fluxes (to the sediment) were estimated for all elements, but these sediments showed authigenic enrichments only for Cd, Cu and U. The short oxygenation period during the winter season did not affect the accumulation of these metals on the shelf. The distribution of Cu, Cd and U have been preserved within the sediments and the authigenic accumulation rates estimated showed a decrease from the deep sections of the core to the surface sediments. This could be explained by a gradual decrease in the strength of the OMZ in the

    Full Text Available Living organizms show cyclic rhythmicity in a variety of physiological, hormonal, behavioral, and psychological processes. Sleep-wake cycles, body temperature, hormone levels, mood and cognition display a circadian rhythm in humans. Delays, advances or desynchronizations of circadian rhythm are known to be strongly associated with mental illness especially mood disorders such as bipolar disorder, major depression and seasonal affective disorder. Furthermore, some of the mood stabilizers, sleep deprivation and light treatment are employed to treat mood disorders by shifting circadian rhythm. This paper reviews the relationship between mood disorders and circadian rhythm, and describes treatment options by altering circadian rhythm.

    Dissemination and implementation of evidence-based psychotherapies is challenging in real world clinical settings. Transdiagnostic Behavior Therapy (TBT) for affective disorders was developed with dissemination and implementation in clinical settings in mind. The present study investigated a voluntary local dissemination and implementation effort, involving 28 providers participating in a four-hour training on TBT. Providers completed immediate (n=22) and six-month follow-up (n=12) training assessments and were encouraged to collect data on their TBT patients (delivery fidelity was not investigated). Findings demonstrated that providers endorsed learning of and interest in using TBT after the training. At six-months, 50% of providers reported using TBT with their patients and their perceived effectiveness of TBT to be very good to excellent. Submitted patient outcome data evidenced medium to large effect sizes. Together, these findings provide preliminary support for the effectiveness of a real world dissemination and implementation of TBT. Published by Elsevier Ltd.

    Recent studies have produced mixed evidence of impairments in facial affect interpretation for children with attention deficit/hyperactivity disorder (ADHD). This study investigated the presence and nature of such impairments across different stimulus formats. Twenty-four boys with ADHD and 24 age-matched comparison boys completed a 72-trial task that included facial expressions of happiness, sadness, fear, anger, surprise, and disgust. Three versions of each expression were used: a static version, a dynamic version, and a dynamic version presented within a relevant situational context. Expressions were also presented in one of two portrayal modes (cartoon versus real-life). Results indicated significant impairments for boys with ADHD on two of the six emotions (fear and disgust), which were consistent across stimulus formats. Directions for further research to identify mediating factors in the expression of such impairments in children with ADHD are discussed.

    Research suggests that cannabis use affects negatively on onset and outcome of schizophrenia, but less is known about possible effects in mood disorders. Bipolar in- and outpatients (N = 3459) were enrolled in an observational study. The influence of cannabis exposure on clinical and social...... treatment outcome measures was examined over the course of 1 year, as well as the effects on these associations of third mediating variables. Over 12 months of treatment, cannabis users exhibited less compliance and higher levels of overall illness severity, mania, and psychosis compared with nonusers....... Additionally, cannabis users experienced less satisfaction with life and had a lower probability of having a relationship compared with nonusers. There was little evidence that cannabis-outcome associations were mediated by third variables. An independent impact of cannabis use on psychopathologic outcomes...

    Affective style (AS) and communication deviance (CD) have been suggested as markers of dysfunctional family environments that may be associated with psychiatric illness. Studies have focused mainly on parental responses during family interactions when an offspring is the identified patient. The present study is unique in examining AS and CD in mothers with unipolar depression, bipolar disorder, or chronic physical illness, and in normal controls. The sample consisted of 64 mothers with children ages 8 to 16. Unipolar mothers were more likely to show negative AS than were any other maternal group. There were no group differences for CD. Chronic stress, few positive life events, and single parenting were associated with AS. CD was associated solely with lower socioeconomic status. Results suggest that dysfunctional interactions are determined not only by maternal psychopathology, but also by an array of contextual factors that are related to the quality of the family environment.

    Full Text Available Most studies investigating the processing of emotions in depressed patients reported impairments in the decoding of negative emotions. However, these studies adopted static stimuli (mostly stereotypical facial expressions corresponding to basic emotions which do not reflect the way people experience emotions in everyday life. For this reason, this work proposes to investigate the decoding of emotional expressions in patients affected by Recurrent Major Depressive Disorder (RMDDs using dynamic audio/video stimuli. RMDDs’ performance is compared with the performance of patients with Adjustment Disorder with Depressed Mood (ADs and healthy (HCs subjects. The experiments involve 27 RMDDs (16 with acute depression - RMDD-A, and 11 in a compensation phase - RMDD-C, 16 ADs and 16 HCs. The ability to decode emotional expressions is assessed through an emotion recognition task based on short audio (without video, video (without audio and audio/video clips. The results show that AD patients are significantly less accurate than HCs in decoding fear, anger, happiness, surprise and sadness. RMDD-As with acute depression are significantly less accurate than HCs in decoding happiness, sadness and surprise. Finally, no significant differences were found between HCs and RMDD-Cs in a compensation phase. The different communication channels and the types of emotion play a significant role in limiting the decoding accuracy.

    According to several studies, the onset of the Borderline Personality Disorder (BPD) depends on the combination between genetic and environmental factors (GxE), in particular between biological vulnerabilities and the exposure to traumatic experiences during childhood. We have searched for studies reporting possible alterations in several biological processes and brain morphological features in relation to childhood trauma experiences and to BPD. We have also looked for epigenetic mechanisms as they could be mediators of the effects of childhood trauma in BPD vulnerability. We prove the role of alterations in Hypothalamic-Pituitary-Adrenal (HPA) axis, in neurotrasmission, in the endogenous opioid system and in neuroplasticity in the childhood trauma-associated vulnerability to develop BPD; we also confirm the presence of morphological changes in several BPD brain areas and in particular in those involved in stress response. Not so many studies are available on epigenetic changes in BPD patients, although these mechanisms are widely investigated in relation to stress-related disorders. A better comprehension of the biological and epigenetic mechanisms, affected by childhood trauma and altered in BPD patients, could allow to identify "at high risk" subjects and to prevent or minimize the development of the disease later in life.

  4. Psychosocial and Pedagogical Means of Reduction of Hyper Dynamic Manifestations Syndrome Within the Affective Personality Disorder

    2017-06-01

    Full Text Available The problem of correction of affective personality disorders (for example, reducing the manifestations of hyper dynamic syndrome, analyzes the main approaches to its solution. We determined the causes and forms of attention deficit disorder with hyperactivity. To characterize the basic correction means reducing the manifestations of hyper dynamic behavior, which includes two areas with different content and psycho social and recreational components. The first direction is connected with the conduct of an individual or group psycho-correction work; the second – social and recreational include tasks aimed at providing social and psychological support to the individual. It is shown that the problem of hyperactive behavior is determined by the individual variability and natural features caused by human development. Psychological studies suggest the importance of external, social factors, primarily adequate forms of organization and communication, the influence of family relations on the manifestations of hyperactivity. It is shown that the implementation of psycho-pedagogical bases of overcoming hyperactivity leads to increased self-esteem, developing the ability to plan and predict their own behavior and, as a consequence – the disclosure of the individual adaptation possibilities.

    The aim of the study was to assess the nutritional value of the food intake in the group of men and women suffering from recurrent affective disorders and schizophrenia, and also to determine the relation between selected nutritional parameters with anthropometric indices defining the nutritional status of the subjects. 219 persons participated in the study (61 patients with recurrent depressive disorders, 60 patients with schizophrenia and 98 healthy volunteers). A24-hour dietary recall was used in the quantitative assessment of the diet. Anthropometric and biochemical measurements as well as body composition analysis were used to assess the nutritional status. It was shown that women with depression and schizophrenia had a significantly higher content of both visceral adipose tissue and subcutaneous adipose tissue as compared with the control group. A diet with a higher content of energy from protein, a higher supply of calcium promoted a lower fat content in the bodies of women suffering from depression (no such relationship was observed in the group of men). In the group of patients with schizophrenia, a diet with a lower supply of energy promoted a lower BMI value, waist circumference, lower waist-hip ratio and a lower fat content in the body. An improper energy structure and an improper content of nutrients can, in the future, contribute to the development of many somatic diseases, thus leading to deterioration of life quality of subjects and preventing the maintenance of mental health.

  7. No effect of ambient odor on the affective appraisal of a desktop virtual environment with signs of disorder.

    Directory of Open Access Journals (Sweden)

    Alexander Toet

    Full Text Available Desktop virtual environments (VEs are increasingly deployed to study the effects of environmental qualities and interventions on human behavior and safety related concerns in built environments. For these applications it is essential that users appraise the affective qualities of the VE similar to those of its real world counterpart. Previous studies have shown that factors like simulated lighting, sound and dynamic elements all contribute to the affective appraisal of a desktop VE. Since ambient odor is known to affect the affective appraisal of real environments, and has been shown to increase the sense of presence in immersive VEs, it may also be an effective tool to tune the affective appraisal of desktop VEs. This study investigated if exposure to ambient odor can modulate the affective appraisal of a desktop VE with signs of public disorder.Participants explored a desktop VE representing a suburban neighborhood with signs of public disorder (neglect, vandalism and crime, while being exposed to either room air or subliminal levels of unpleasant (tar or pleasant (cut grass ambient odor. Whenever they encountered signs of disorder they reported their safety related concerns and associated affective feelings.Signs of crime in the desktop VE were associated with negative affective feelings and concerns for personal safety and personal property. However, there was no significant difference between reported safety related concerns and affective connotations in the control (no-odor and in each of the two ambient odor conditions.Ambient odor did not affect safety related concerns and affective connotations associated with signs of disorder in the desktop VE. Thus, semantic congruency between ambient odor and a desktop VE may not be sufficient to influence its affective appraisal, and a more realistic simulation in which simulated objects appear to emit scents may be required to achieve this goal.

    The co-segregation in one pedigree of bipolar affective disorder with Darier's disease whose gene is on chromosome 12q23-q24.1, and findings from linkage and association studies with the neighbouring gene of phospholipase A2 (PLA2) indicate that PLA2 may be considered as a candidate gene for affective disorders. All relevant genetic association studies, however, were conducted on bipolar patients. In the present study, the possible association between the PLA2 gene and unipolar affective disorder was examined on 321 unipolar patients and 604 controls (all personally interviewed), recruited from six countries (Belgium, Bulgaria, Croatia, Germany, Greece, and Italy) participating in the European Collaborative Project on Affective Disorders. After controlling for population group and gender, one of the eight alleles of the investigated marker (allele 7) was found to be more frequent among unipolar patients with more than three major depressive episodes than among controls (P<0.01); genotypic association was also observed, under the dominant model of genetic transmission (P<0.02). In addition, presence of allele 7 was correlated with a higher frequency of depressive episodes (P<0.02). These findings suggest that structural variations at the PLA2 gene or the chromosomal region around it may confer susceptibility for unipolar affective disorder.

    This study was carried out to examine the impact of several climate variables on the pregnancy rate after cervical artificial insemination (AI) of Rasa Aragonesa ewes. Data were derived from 8,977 inseminations in 76 well-managed flocks performed during the first month of the breeding season (July to October). The following data were recorded for each animal: farm, year, month of AI, parity, lambing-treatment interval, inseminating ram, AI technician, and climatic variables such as mean, maximum and minimum temperature, mean and maximum relative humidity, rainfall, and mean and maximum temperature-humidity index (THI) for each day from day 12 before AI to day 14 post-AI. Means were furthermore calculated for the following periods around AI (day 0): -12 to 0, -2 to 0, AI day, 0 to 2, and 0 to 14. Logistic regression analysis indicated that the likelihood of pregnancy decreased when maximum temperature in the 2 days prior to AI was higher than 30 °C (by a factor of 0.81). Fertility was also lower for primiparous ewes and in multiparous ewes with more than five previous parturitions. Other factors with significant impact on fertility were flock, technician, inseminating ram, and a lambing-AI interval longer than 240 days. It was concluded that the 2 days prior to AI seems to be the period when heat stress had the greatest impact on pregnancy rate in Rasa Aragonesa ewes.

    Chromite ore processing residue (COPR) is generated by the roasting of chromite ores for the extraction of chromium. Leaching of carcinogenic hexavalent chromium (Cr(VI)) from COPR dumpsites and contamination of groundwater is a key environmental risk. The objective of the study was to evaluate Cr(VI) contamination in groundwater in the vicinity of three COPR disposal sites in Uttar Pradesh, India, in the pre-monsoon and monsoon seasons. Groundwater samples (n = 57 pre-monsoon, n = 70 monsoon) were taken in 2014 and analyzed for Cr(VI) and relevant hydrochemical parameters. The site-specific ranges of Cr(VI) concentrations in groundwater were Rania), <0.005 to 115 mg L -1 (Chhiwali), and <0.005 to 2.0 mg L -1 (Godhrauli). Maximum levels of Cr(VI) were found close to the COPR dumpsites and significantly exceeded safe drinking water limits (0.05 mg L -1 ). No significant dependence of Cr(VI) concentration on monsoons was observed.

    The aim of the present study was to select appropriate film clips with a general vs. eating disorder (ED)-related content to induce negative affect. More specifically, the study examined the subjective emotional experience (valence, arousal, anxiety, induction of somatic symptoms, and ability to control reactions during film clips) of Greek-Cypriot university students (N = 79) in response to three types of film clips: general unpleasant, ED-specific unpleasant, and emotionally neutral. In addition, the study aimed to compare the emotional reactions to the aforementioned clips between two groups of participants differing on their risk for ED (high vs. low). Preliminary results indicate the clips with general content ("The Champ") and with ED-specific content ("Binge eating") that are most effective in inducing negative affect and differentiating between risk groups. These clips provide an effective method for emotion induction that can be used for assessing the emotional experience of individuals with ED symptoms, since their emotional experience is significantly implicated in the development and maintenance of their symptoms (Merwin, Clin Psychol Sci Pract 18(3):208-214, 2011).Level of evidence No level of evidence, Experimental Study.

    There is evidence that certain patients with schizophrenia have deficits in theory of mind (ToM) capabilities. It is, however, unclear whether these are symptom or diagnosis-specific. A ToM hinting task was given to 15 patients with a DSM-IV diagnosis of schizophrenia, 15 patients with affective disorder and 15 healthy controls. Severity of the current psychopathology was measured using the Krawiecka standardised scale of psychotic symptoms (Krawiecka, Goldberg, & Vaughan, 1977); IQ was estimated via the Ammons and Ammons Quick Test (Ammons & Ammons, 1962). The group with schizophrenia performed significantly worse than the affective and control groups. Poor performance on the hinting task was found to be significantly related to the presence of positive symptoms (instead of negative ones) and specifically related to delusions and hallucinations. These findings remained when covariance for potentially confounding variables was applied. Individuals with high levels of delusions and hallucinations performed significantly worse on this ToM task, regardless of diagnosis, implying ToM impairment is not exclusive to schizophrenia but is evident in other forms of psychosis. Between-group analyses showed the schizophrenia group had a significantly poorer performance on this task than the others.

    Disrupted structural connectivity is associated with psychiatric illnesses including bipolar disorder (BP). Here we use structural brain network analysis to investigate connectivity abnormalities in multiply affected BP type I families, to assess the utility of dysconnectivity as a biomarker and its endophenotypic potential. Magnetic resonance diffusion images for 19 BP type I patients in remission, 21 of their first degree unaffected relatives, and 18 unrelated healthy controls underwent tractography. With the automated anatomical labelling atlas being used to define nodes, a connectivity matrix was generated for each subject. Network metrics were extracted with the Brain Connectivity Toolbox and then analysed for group differences, accounting for potential confounding effects of age, gender and familial association. Whole brain analysis revealed no differences between groups. Analysis of specific mainly frontal regions, previously implicated as potentially endophenotypic by functional magnetic resonance imaging analysis of the same cohort, revealed a significant effect of group in the right medial superior frontal gyrus and left middle frontal gyrus driven by reduced organisation in patients compared with controls. The organisation of whole brain networks of those affected with BP I does not differ from their unaffected relatives or healthy controls. In discreet frontal regions, however, anatomical connectivity is disrupted in patients but not in their unaffected relatives. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Using Ecological Momentary Assessment, the within patient associations between drive for thinness, emotional states, momentary urge to be physically active and physical activity were studied in 32 inpatients with an eating disorder. Participants received an electronic device and had to indicate at nine random times a day during 1 week their momentary drive for thinness, positive and negative emotional states and their urge to be physically active and physical activity. Multilevel analyses indicated that patients with higher mean levels for urge to be physically active were characterized by lower body mass index (BMI) and chronically negative affect whereas patients with higher mean levels for physical activity were characterized by lower BMI and higher dispositions for drive for thinness. In addition, within patient relations between drive for thinness and urge to be physically active were moderated by BMI and chronically negative affect whereas within patient relations between drive for thinness and physical activity were moderated by BMI. Finally, also positive emotional states were significantly associated with physical activity within patients. By using a daily process design, characteristics of physical activity were revealed that have not been identified with assessment methods that have a lower time resolution.

    Although deficits in memory and cognitive processing are evident in post-traumatic stress disorder (PTSD), difficulties with social cognition and the impact of such difficulties on interpersonal functioning are poorly understood. Here, we examined the ability of women diagnosed with PTSD related to childhood abuse to discriminate affective prosody, a central component of social cognition. Women with PTSD and healthy controls (HCs) completed two computer-based tasks assessing affective prosody: (i) recognition (categorizing foreign-language excerpts as angry, fearful, sad, or happy) and (ii) discrimination (identifying whether two excerpts played consecutively had the 'same' or 'different' emotion). The association of performance with symptom presentation, trauma history, and interpersonal functioning was also explored. Women with PTSD were slower than HCs at identifying happiness, sadness, and fear, but not anger in the speech excerpts. The presence of dissociative symptoms was related to reduced accuracy on the discrimination task. An increased severity of childhood trauma was associated with reduced accuracy on the discrimination task and with slower identification of emotional prosody. Exposure to childhood trauma is associated with long-term, atypical development in the interpretation of prosodic cues in speech. The findings have implications for the intergenerational transmission of trauma. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    This research sought to determine whether smoking influences affect by means other than withdrawal reduction. Little previous evidence suggests such an effect. We surmised that such an effect would be especially apparent in posttraumatic stress disorder (PTSD) and major depressive disorder (MDD), two disorders that are frequently comorbid with smoking and that involve dysregulated affect. Participants were US veterans who were regular smokers (N=159): 52 with PTSD (58% with comorbid MDD); 51 with MDD, and 56 controls with no psychiatric disorder. During three positive and three negative mood induction trials (scheduled over two sessions), non-withdrawn participants smoked either a nicotine-containing cigarette (NIC+), a nicotine-free cigarette (NIC−), or held a pen. Positive and negative affect were each measured before and after mood induction. Results showed a significant 2-way interaction of smoking condition x time on negative affect during the negative mood induction [F(6, 576)=2.41, p=.03] in those with PTSD and controls. In these groups, both NIC+ and NIC−, relative to pen, produced lower negative affect ratings following the negative mood induction. There was also a 2-way interaction of smoking condition x time on positive affect response to the positive mood induction amongst those with PTSD and controls F(6, 564)=3.17, p= .005] and amongst MDD and controls [F(6, 564)=2.27, p= .036]. Amongst all smokers, NIC+ enhanced the magnitude and duration of positive affect more than did NIC−. Results revealed affect modulation outside the context of withdrawal relief; such effects may motivate smoking among those with psychiatric diagnoses, and among smokers in general. PMID:28004948

    Borderline Personality Disorder (BPD) and Bipolar Affective Disorder (BD) have clinical characteristics in common which often make their differential diagnosis difficult. The history of early life stress (ELS) may be a differentiating factor between BPD and BD, as well as its association with clinical manifestations and specific neuroendocrine responses in each of these diagnoses. Assessing and comparing patients with BD and BPD for factors related to symptomatology, etiopathogenesis and neuroendocrine markers. The study sample consisted of 51 women, divided into 3 groups: patients with a clinical diagnosis of BPD (n = 20) and BD (n = 16) and healthy controls (HC, n = 15). Standardized instruments were used for the clinical evaluation, while the history of ELS was quantified with the Childhood Trauma Questionnaire (CTQ), and classified according to the subtypes: emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect. The functioning of the hypothalamic-pituitary-adrenal (HPA) axis was evaluated by measuring a single plasma cortisol sample. Patients with BPD presented with more severe psychiatric symptoms of: anxiety, impulsivity, depression, hopelessness and suicidal ideation than those with BD. The history of ELS was identified as significantly more prevalent and more severe in patients (BPD and BP) than in HC. Emotional abuse, emotional neglect and physical neglect also showed differences and were higher in BPD than BD patients. BPD patients had greater severity of ELS overall and in the subtypes of emotional abuse, emotional neglect and physical neglect than BD patients. The presence of ELS in patients with BPD and BP showed significant difference with lower cortisol levels when compared to HC. The endocrine evaluation showed no significant differences between the diagnoses of BPD and BD. Cortisol measured in patients with BPD was significantly lower compared to HC in the presence of emotional neglect and physical

    BACKGROUND: The association between affective disorder and subsequent dementia is unclear. Our aim was to investigate whether patients with unipolar or bipolar affective disorder have an increased risk of developing dementia compared to patients with other chronic illnesses. METHOD: By linkage...... of the psychiatric and somatic nation-wide registers of all hospitalised patients in Denmark, 2007 patients with mania, 11741 patients with depression, 81380 patients with osteoarthritis and 69149 patients with diabetes were identified according to diagnosis at first-ever discharge from a psychiatric or somatic...... hospital between 1 January 1977 and 31 December 1993. The risk of receiving a diagnosis of dementia on subsequent re-admission was estimated with the use of survival analyses. RESULTS: Patients with unipolar or bipolar affective disorder had a greater risk of receiving a diagnosis of dementia than patients...

  20. Designing affective video games to support the social-emotional development of teenagers with autism spectrum disorders.

    2009-01-01

    Autism spectrum disorders (ASD) are a group of developmental neuropsychiatric disorders, comprised of three diagnostic entities - autistic disorder (AD), Asperger's disorder (AS), and Pervasive Developmental Disorder Not Otherwise Specified (including atypical autism) (PDD-NOS). A number of intervention techniques are currently used to reduce some of the associated challenges, with techniques ranging from behavioral therapy to dietary interventions and traditional counseling. This positional paper proposes the use of video games which leverage affective computing technologies as intervention in autism spectrum disorders in the context of the use of traditional play therapy with adolescents, who may feel uncomfortable engaging in traditional play with toys they may be too old for. It aims to explore the potential for greater 'social physics' made possible by affective computing technologies. This involves computationally 'recognizing' emotions in a user, often through the use of multimodal affective sensors, including facial expressions, postural shifts, and physiological signals such as heart rate, skin conductivity, and EEG signals. However, it is suggested that this should be augmented by researching the effect of social game design mechanisms on social-emotional development, particularly for those who experience difficulty with social interaction.

    Research in context: Due to lack of biological markers, diagnosis and treatment of psychiatric disorders are subjective. There is utmost urgency to identify biomarkers for clinics, research, and drug development. We found that XIST and KDM5C gene expression may be used as a biological marker for diagnosis of major affective disorders in a significantly large subset of female patients from the general population. Our studies show that over-expression of XIST and some X-linked escapee genes may be a common mechanism for development of psychiatric disorders between the patients with rare genetic diseases (XXY or XXX and the general population of female psychiatric patients.

  2. Hiding from the moonlight: luminosity and temperature affect activity of Asian nocturnal primates in a highly seasonal forest.

    Full Text Available The effect of moonlight and temperature on activity of slow lorises was previously little known and this knowledge might be useful for understanding many aspects of their behavioural ecology, and developing strategies to monitor and protect populations. In this study we aimed to determine if the activity of the pygmy loris (Nycticebus pygmaeus is affected by ambient temperature and/or moonlight in a mixed deciduous forest. We radio-collared five females and five males in the Seima Protection Forest, Cambodia, in February to May, 2008 and January to March, 2009 and recorded their behaviour at 5 minutes intervals, totalling 2736 observations. We classified each observation as either inactive (sleeping or alert or active behaviour (travel, feeding, grooming, or others. Moon luminosity (bright/dark and ambient temperature were recorded for each observation. The response variable, activity, was binary (active or inactive, and a logit link function was used. Ambient temperature alone did not significantly affect mean activity. Although mean activity was significantly affected by moonlight, the interaction between moonlight and temperature was also significant: on bright nights, studied animals were increasingly more active with higher temperature; and on dark nights they were consistently active regardless of temperature. The most plausible explanation is that on bright cold nights the combined risk of being seen and attacked by predators and heat loss outweigh the benefit of active behaviours.

However, the distinct contributions of relational impairment (operationalized in the form fears of closeness or abandonment), affect dysregulation (operationalized in the form of overregulation and under-regulation of affect), and identity alterations (operationalized in the form of positive or negative psychoform or somatoform dissociation) to the relationship between childhood trauma and CPTSD/DESNOS have not been systematically tested. Method and Results : In a clinical sample of adults diagnosed with severe and chronic psychiatric and personality disorders ( n  = 472; M  = 34.7 years, SD  = 10.1), structural equation modelling with bootstrap 95% confidence intervals demonstrated that the association between childhood trauma and CPTSD/DESNOS symptoms in adulthood was partially mediated by under-regulation of affect, negative psychoform dissociation, and adult relational fears of closeness and of abandonment. These results also were independent of the effects of borderline personality disorder (BPD) symptoms. Conclusions : Some, but not all, hypothesized components of the DESNOS formulation of CPTSD statistically mediate the relationship between childhood trauma and adult CPTSD/DESNOS. These relationships appear specific to CPTSD/DESNOS and not to the effects of another potential sequelae of childhood trauma BPD. Replication with prospective longitudinal studies is needed.

    OBJECTIVE: To examine the effect of prenatal exposure to severe life events on risk of affective disorders in the offspring. METHODS: In a cohort of 1.1 million Danish births from May 1978 until December 1997, mothers were considered exposed if one (or more) of their close relatives died or was diagnosed with serious illness up to 6 months before conception or during pregnancy. Offspring were followed up from their 10th birthday until their death, migration, onset of affective disorder or 31 December 2007; hospital admissions were identified by linkage to the Central Psychiatric Register. Log-linear Poisson regression was used for data analysis. RESULTS: The risk of affective disorders was increased in male offspring whose mothers were exposed to severe life events during the second trimester (adjusted RR 1.55 [95% CI 1.05-2.28]). There was an increased risk of male offspring affective disorders in relation to maternal exposure to death of a relative in the second trimester (adjusted RR 1.74 [95% CI 1.06-2.84]) or serious illness in a relative before pregnancy (adjusted RR 1.44 [95% CI 1.02-2.05]). There was no evidence for an association between prenatal exposure to severe life events and risk of female offspring affective disorders. CONCLUSIONS: Our population-based study suggests that prenatal maternal exposure to severe life events may increase the risk of affective disorders in male offspring. These findings are consistent with studies of populations exposed to famine and earthquake disasters which indicate that prenatal environment may influence the neurodevelopment of the unborn child.

    Reduced resilience, a construct associated with maladaptive stress coping and a predisposing vulnerability for Functional Neurological Disorders (FND), has been under-studied compared to other neuropsychiatric factors in FND. This prospective case-control study investigated self-reported resilience in patients with FND compared to controls and examined relationships between resilience and affective symptoms, personality traits, alexithymia, health status and adverse life event burden. 50 individuals with motor FND and 47 healthy controls participated. A univariate test followed by a logistic regression analysis investigated group-level differences in Connor-Davidson Resilience Scale (CD-RISC) scores. For within-group analyses performed separately in patients with FND and controls, univariate screening tests followed by multivariate linear regression analyses examined factors associated with self-reported resilience. Adjusting for age, gender, education status, ethnicity and lifetime adverse event burden, patients with FND reported reduced resilience compared to controls. Within-group analyses in patients with FND showed that individual-differences in mental health, extraversion, conscientiousness, and openness positively correlated with CD-RISC scores; post-traumatic stress disorder symptom severity, depression, anxiety, alexithymia and neuroticism scores negatively correlated with CD-RISC scores. Extraversion independently predicted resilience scores in patients with FND. In control subjects, univariate associations were appreciated between CD-RISC scores and gender, personality traits, anxiety, alexithymia and physical health; conscientiousness independently predicted resilience in controls. Patients with FND reported reduced resilience, and CD-RISC scores covaried with other important predisposing vulnerabilities for the development of FND. Future research should investigate if the CD-RISC is predictive of clinical outcomes in patients with FND. Copyright

  6. Early affective processing in patients with acute posttraumatic stress disorder: magnetoencephalographic correlates.

    Full Text Available In chronic PTSD, a preattentive neural alarm system responds rapidly to emotional information, leading to increased prefrontal cortex (PFC activation at early processing stages (<100 ms. Enhanced PFC responses are followed by a reduction in occipito-temporal activity during later processing stages. However, it remains unknown if this neuronal pattern is a result of a long lasting mental disorder or if it represents changes in brain function as direct consequences of severe trauma.The present study investigates early fear network activity in acutely traumatized patients with PTSD. It focuses on the question whether dysfunctions previously observed in chronic PTSD patients are already present shortly after trauma exposure. We recorded neuromagnetic activity towards emotional pictures in seven acutely traumatized PTSD patients between one and seven weeks after trauma exposure and compared brain responses to a balanced healthy control sample. Inverse modelling served for mapping sources of differential activation in the brain.Compared to the control group, acutely traumatized PTSD patients showed an enhanced PFC response to high-arousing pictures between 60 to 80 ms. This rapid prefrontal hypervigilance towards arousing pictorial stimuli was sustained during 120-300 ms, where it was accompanied by a reduced affective modulation of occipito-temporal neural processing.Our findings indicate that the hypervigilance-avoidance pattern seen in chronic PTSD is not necessarily a product of an endured mental disorder, but arises as an almost immediate result of severe traumatisation. Thus, traumatic experiences can influence emotion processing strongly, leading to long-lasting changes in trauma network activation and expediting a chronic manifestation of maladaptive cognitive and behavioral symptoms.

    Autism spectrum disorder (ASD) is a highly heritable neurodevelopmental disorder with a complex genetic architecture. To identify genetic variants underlying ASD, we performed single-variant and gene-based genome-wide association studies using a dense genotyping array containing over 2.3 million single-nucleotide variants in a discovery sample of 160 families with at least one child affected with non-syndromic ASD using a binary (ASD yes/no) phenotype and a quantitative autistic trait. Replication of the top findings was performed in Psychiatric Genomics Consortium and Erasmus Rucphen Family (ERF) cohort study. Significant association of quantitative autistic trait was observed with the TTC25 gene at 17q21.2 (effect size=10.2, P-value=3.4 × 10 -7 ) in the gene-based analysis. The gene also showed nominally significant association in the cohort-based ERF study (effect=1.75, P-value=0.05). Meta-analysis of discovery and replication improved the association signal (P-value meta =1.5 × 10 -8 ). No genome-wide significant signal was observed in the single-variant analysis of either the binary ASD phenotype or the quantitative autistic trait. Our study has identified a novel gene TTC25 to be associated with quantitative autistic trait in patients with ASD. The replication of association in a cohort-based study and the effect estimate suggest that variants in TTC25 may also be relevant for broader ASD phenotype in the general population. TTC25 is overexpressed in frontal cortex and testis and is known to be involved in cilium movement and thus an interesting candidate gene for autistic trait.

    Caregivers of people with mental illnesses often experience a wide range of burdens. Although many studies have confirmed burdens among family caregivers of mentally ill relatives in general, specific knowledge regarding the concrete everyday hassle and existential sorrows from the caregiverś subjective reasoning perspective is lacking. Furthermore, there is little evidence on the possible different effects of affective disorders and schizophrenia on the quality of burden; this is also true with regard to the role of cultural traditions and lay beliefs. The aim of this study was to explore the specific burdens experienced by caregivers of patients with schizophrenia and affective disorders. A qualitative study was conducted by semi-structured interviews with 45 caregivers of patients with schizophrenia and affective disorders. Data were analysed by qualitative content analysis. Eleven encumbering themes resulted from the interviews including incertitude, unawareness, emotional burden, stigma and blame, financial burden, physical burden, restriction in routine, disruption in routine, dissatisfaction with family, relatives, and acquaintances, troubles with patients' adherence to medication, and problems with health services and governmental support. Caring for a person with mental illness affects caregivers emotionally, financially, physically, and it elicits some restrictions in their routine (daily hassles). Finally, it causes conflicts in family relationships. Despite some differences regarding perceived burden among caregivers of schizophrenia and affective disorders, a common pattern of burden could be identified. Thus, authorities should provide adequate financial, educational, and psychosocial supports for caregivers of mental illnesses.

    Sick leave and unemployment are highly prevalent among people with affective disorders. Their depression severity is disabling and inversely related to having employment. No evidence-based vocational rehabilitation exists for this target group. Knowledge is therefore needed to understand the psychosocial factors that affect depression severity in order to develop new rehabilitation interventions. This study examined relationships between depression severity and empowerment, working life aspirations, occupational engagement, and quality of life in unemployed people with affective disorders receiving mental healthcare. In this cross-sectional study of 61 participants, instruments on psychosocial factors and questions on descriptive sociodemographic and clinical characteristics were administered. Descriptive, correlation, and regression statistics were applied. Correlation and regression analyses showed significant inverse relations between depression severity and empowerment and quality of life. The odds for more severe depression decreased with higher empowerment and quality of life. However, neither extent of engagement in daily life nor working life aspiration was related to depression severity. An empowerment approach and strategies, which support the quality of life, are needed in development of vocational rehabilitation interventions, and bridging of mental healthcare and vocational services. Implications for Rehabilitation Enhancing empowerment and quality life in the return to work process can decrease depression severity in unemployed people with affective disorder. There is a need to address work issues in addition to symptom reduction in primary and mental healthcare. Bridging the service and time gap between vocational rehabilitation and healthcare is recommended for mitigating long-term unemployment for people with affective disorders who want to work.

    The aim of this study is to determine odds of aggression and associated factors in patients with schizophrenia-spectrum disorders (SSD) and affective disorders who were evaluated in an emergency department setting. A retrospective study was conducted using de-identified data from electronic medical records from 3.322 patients who were evaluated at emergency psychiatric settings. Data extracted included demographic information, variables related to aggression towards people or property in the past 6months, and other factors that could potentially impact the risk of aggression, such as comorbid diagnoses, physical abuse and sexual abuse. Bivariate analyses and multivariate regression analyses were conducted to determine the variables significantly associated with aggression. An initial multivariate regression analysis showed that SSD had 3.1 times the odds of aggression, while bipolar disorder had 2.2 times the odds of aggression compared to unipolar depression. A second regression analysis including bipolar subtypes showed, using unipolar depression as the reference group, that bipolar disorder with a recent mixed episode had an odds ratio (OR) of 4.3, schizophrenia had an OR of 2.6 and bipolar disorder with a recent manic episode had an OR of 2.2. Generalized anxiety disorder was associated with lower odds in both regression analyses. As a whole, the SSD group had higher odds of aggression than the bipolar disorder group. However, after subdividing the groups, schizophrenia had higher odds of aggression than bipolar disorder with a recent manic episode and lower odds of aggression than bipolar disorder with a recent mixed episode.

    Full Text Available The objective of the study was to determine the quality and fatty acid profiles of mutton cuts purchased from rural and urban localities in South Africa. Five hundred and ten samples were collected in four seasons from both rural and urban shops and butcheries. Samples were immediately transported to the laboratory in cooler boxes with ice where the following physico-chemical characteristics of mutton were determined; meat pH, color (L*, a*, and b*, cooking losses and Warner Braztler shear force and replicates stored at −20°C pending fatty acid analysis. Meat L* values were lowest (24.7±0.49 in winter and highest (32.2±0.49 in spring. The loin and sirloin cuts recorded the highest intramuscular fat whilst rib and leg cuts recorded the lowest intramuscular fat. In conclusion intramuscular fat, fatty acid profiles and physico-chemical quality of mutton were significantly affected by season and meat portion and not necessarily by the locality and class of shop.

    To evaluate the positive aspects of caregiving and its correlates (socio-demographic and clinical variables, caregiver burden, coping, quality of life, psychological morbidity) in the primary caregivers of patients with bipolar affective disorder (BPAD). A total of 60 primary caregivers of patients with a diagnosis of BPAD were evaluated on the Scale for Positive Aspects of Caregiving Experience (SPACE) and the Hindi version of Involvement Evaluation Questionnaire, Family Burden Interview Schedule (FBIS), modified Hindi version of Coping Checklist, shorter Hindi version of the World Health Organization Quality of Life (WHOQOL-BREF), and Hindi translated version of 12-item General Health Questionnaire (GHQ-12). Caregivers of patients with BPAD had the highest mean score in the SPACE domain of Motivation for caregiving role (2.45), followed by Caregiver satisfaction (2.38) and Caregiving personal gains (2.20). The mean score was the lowest for the domain of Self-esteem and social aspect of caring (2.01). In terms of correlations, age of onset of BPAD had a negative correlation with various domains of SPACE. The mean number of total lifetime affective and depressive episodes correlated positively with Self-esteem and social aspect of caring. Caregiver satisfaction correlated negatively with FBIS domains of Disruption of routine family activities, Effect on mental health of others, and subjective burden. Coercion as a coping mechanism correlated positively with domains of Caregiving personal gains, Caregiver satisfaction, and the total score on SPACE. Three (Physical health, Psychological health, Environment) out of 5 domains of the WHOQOL-BREF correlated positively with the total SPACE score. No association was noted between GHQ-12 and SPACE scores. Positive caregiving experience in primary caregivers of patients with BPAD is associated with better quality of life of the caregivers.

    As the result of extensive translational and cross-disciplinary research, attachment theory is now a construct with significant neuropsychiatric traction. The correlation of attachment with other influential conceptual models (i.e. temperament and personality) is therefore of interest. Consequently, we explored how two attachment dimensions (attachment anxiety and attachment avoidance) correlated with measures of temperament and personality in 357 psychiatric outpatients. We performed a retrospective review of four questionnaires (the Experiences in Close Relationship scale (ECR-R), Temperament and Character inventory (TCI), Temperament Evaluation of the Memphis, Pisa, Paris and San Diego questionnaire (TEMPS-A), and Personality Self-Portrait Questionnaire (PSQ)). Frequency measures and correlations were examined, as was the predictive value of attachment security for a personality disorder (PD). Significant, robust correlations were found between attachment anxiety and (1) several negative affective temperaments (dysthymic and cyclothymic); (2) several indices of personality pathology (low self-directedness (TCI), DSM-IV paranoid, borderline, histrionic, avoidant and dependent personality traits). Attachment avoidance had fewer large correlations. In an exploratory model, the negative predictive value of attachment security for a PD was 86%. Subjects were a relatively homogeneous subset of ambulatory psychiatric outpatients. PD diagnoses were via self-report. Clinically, these findings highlight the significant overlap between attachment, affective temperament, and personality and support the value of attachment as a screen for PDs. More broadly, given our growing understanding of the neurobiology of attachment (i.e. links with the oxytocin system), these results raise interesting questions about underlying biological systems and psychiatric treatment. © 2013 Elsevier B.V.

    Studies have suggested an increased risk of criminality in juveniles if they suffer from co-morbid Attention Deficit Hyperactivity Disorder (ADHD) along with Conduct Disorder. The Structured Assessment of Violence Risk in Youth (SAVRY), the Psychopathy Checklist Youth Version (PCL:YV), and Youth Level of Service/Case Management Inventory (YLS/CMI) have been shown to be good predictors of violent and non-violent re-offending. The aim was to compare the accuracy of these tools to predict violent and non-violent re-offending in young people with co-morbid ADHD and Conduct Disorder and Conduct Disorder only. The sample included 109 White-British adolescent males in secure settings. Results revealed no significant differences between the groups for re-offending. SAVRY factors had better predictive values than PCL:YV or YLS/CMI. Tools generally had better predictive values for the Conduct Disorder only group than the co-morbid group. Possible reasons for these findings have been discussed along with limitations of the study. Copyright © 2014 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

    Affective disorders such as major depression are among the most prevalent and costly diseases of the central nervous system, but the underlying mechanisms are still poorly understood. In recent years, it has become evident that alterations of the stress hormone system, in particular dysfunctions (hyper- or hypo-activity) of the hypothalamic-pituitary-adrenal (HPA) axis, play a prominent role in the development of major depressive disorders. Therefore, we aimed to generate a new animal model comprising these neuroendocrine core symptoms in order to unravel parameters underlying increased or decreased stress reactivity. Starting from a population of outbred mice (parental generation: 100 males and 100 females of the CD-1 strain), two breeding lines were established according to the outcome of a 'stress reactivity test' (SRT), consisting of a 15-min restraint period and tail blood samplings immediately before and after exposure to the stressor. Mice showing a very high or a very low secretion of corticosterone in the SRT, i.e. animals expressing a hyper- or a hypo-reactivity of the HPA axis, were selected for the 'high reactivity' (HR) and the 'low reactivity' (LR) breeding line, respectively. Additionally, a third breeding line was established consisting of animals with an 'intermediate reactivity' (IR) in the SRT. Already in the first generation, i.e. animals derived from breeding pairs selected from the parental generation, significant differences in the reactivity of the HPA axis between HR, IR, and LR mice were observed. Moreover, these differences were found across all subsequent generations and could be increased by selective breeding, which indicates a genetic basis of the respective phenotype. Repeated testing of individuals in the SRT furthermore proved that the observed differences in stress responsiveness are present already early in life and can be regarded as a robust genetic predisposition.

    The symptoms of emotional dysregulation associated with the syndrome known as pseudobulbar affect (PBA) can be effectively treated by the sigma, glutamate, and serotonergic agent dextromethorphan combined with quinidine. If the same brain circuits affected in PBA are also compromised in related disorders of emotional expression, dextromethorphan-quinidine and other novel sigma-glutamate-serotonin agents could prove to be novel psychopharmacologic treatments for these conditions as well.

  18. A Proposed Functional Abilities Classification Tool for Developmental Disorders Affecting Learning and Behaviour

    2018-02-01

    Full Text Available Children with developmental disorders affecting learning and behaviour (DDALB (e.g., attention, social communication, language, and learning disabilities, etc. require individualized support across multiple environments to promote participation, quality of life, and developmental outcomes. Support to enhance participation is based largely on individual profiles of functioning (e.g., communication, cognitive, social skills, executive functioning, etc., which are highly heterogeneous within medical diagnoses. Currently educators, clinicians, and parents encounter widespread difficulties in meeting children’s needs as there is lack of universal classification of functioning and disability for use in school environments. Objective: a practical tool for functional classification broadly applicable for children with DDALB could facilitate the collaboration, identification of points of entry of support, individual program planning, and reassessment in a transparent, equitable process based on functional need and context. We propose such a tool, the Functional Abilities Classification Tool (FACT based on the concepts of the ICF (International Classification of Functioning, Disability and Health. FACT is intended to provide ability and participation classification that is complementary to medical diagnosis. For children presenting with difficulties, the proposed tool initially classifies participation over several environments. Then, functional abilities are classified and personal factors and environment are described. Points of entry for support are identified given an analysis of functional ability profile, personal factors, environmental features, and pattern of participation. Conclusion: case examples, use of the tool and implications for children, agencies, and the system are described.

    Full Text Available The present investigation was undertaken to examine the effects of mindfulness-based cognitive therapy (MBCT on interepisodic symptoms, emotional regulation, and quality of life in patients with bipolar affective disorder (BPAD in remission. The sample for the study comprised a total of five patients with the diagnosis of BPAD in partial or complete remission. Each patient was screened to fit the inclusion and exclusion criteria and later assessed on the Beck Depressive Inventory I, Beck Anxiety Inventory, Difficulties in Emotion Regulation Scale, Acceptance and Action Questionnaire-II, and The World Health Organization Quality of Life Assessment-BREF. Following preassessments, patients underwent 8–10 weeks of MBCT. A single case design with pre- and post-intervention assessment was adopted to evaluate the changes. Improvement was observed in all five cases on the outcome variables. The details of the results are discussed in the context of the available literature. Implications, limitations, and ideas for future investigations are also discussed.

    An attentional bias for trauma-related verbal cues was frequently demonstrated in posttraumatic stress disorder (PTSD) using variants of the emotional Stroop task (EST). However, the mechanisms underlying the Stroop-effect are ill-defined and it is yet unclear how the findings apply to different paradigms and stimulus modalities. To address these open questions, for the first time a spatial-cuing task with pictorial cues of different emotional valence was administered to trauma-exposed individuals with and without PTSD, and non-trauma-exposed controls. Groups did not show different response profiles across affective conditions. However, a group effect was evident when comparing depressed with non-depressed individuals: Those with depression showed delayed attending towards trauma-related cues and faster attending away from negative cues. In correlational analyses, attentional avoidance was associated with both depression and PTSD symptom severity. These findings highlight the need for research on trauma populations and anxiety in general to pay closer attention to depression as an important confound in the study of emotional information processing.

  1. Working memory load affects repetitive behaviour but not cognitive flexibility in adolescent autism spectrum disorder.

    2017-03-16

    Autism spectrum disorder (ASD) is associated with repetitive and stereotyped behaviour, suggesting that cognitive flexibility may be deficient in ASD. A central, yet not examined aspect to understand possible deficits in flexible behaviour in ASD relates (i) to the role of working memory and (ii) to neurophysiological mechanisms underlying behavioural modulations. We analysed behavioural and neurophysiological (EEG) correlates of cognitive flexibility using a task-switching paradigm with and without working memory load in adolescents with ASD and typically developing controls (TD). Adolescents with ASD versus TD show similar performance in task switching with no memory load, indicating that 'pure' cognitive flexibility is not in deficit in adolescent ASD. However performance during task repetition decreases with increasing memory load. Neurophysiological data reflect the pattern of behavioural effects, showing modulations in P2 and P3 event-related potentials. Working memory demands affect repetitive behaviour while processes of cognitive flexibility are unaffected. Effects emerge due to deficits in preparatory attentional processes and deficits in task rule activation, organisation and implementation of task sets when repetitive behaviour is concerned. It may be speculated that the habitual response mode in ASD (i.e. repetitive behaviour) is particularly vulnerable to additional demands on executive control processes.

    The use of service dogs for children with autism spectrum disorder is a relatively new and growing assistance-dog application. The objectives of this article were to identify and describe the factors influencing an autism service dog's performance and the impact of this type of placement on the dog's welfare. A qualitative approach uses interview and observational data to characterize the dogs' behaviors and welfare with relevancy to the dogs' home environments. Identification of potential physical stressors included lack of rest or recovery time after working, unintentional maltreatment and prodding by children with autism, lack of predictability in daily routines, and insufficient opportunities for recreational activities. Results revealed that these dogs formed social relationships primarily with the parents and second with the children with autism. Failure to recognize and respond to the identified physical, emotional, and social needs can have serious impacts on the behavior, welfare, and performance of these autism service dogs, as well as parental satisfaction. As applications of service dogs expand to new domains, there is a need to assess and understand factors and variables affecting the relationship between family and service dog to ensure continued success of these programs.

  3. Face and Word Recognition Can Be Selectively Affected by Brain Injury or Developmental Disorders.

    Robotham, Ro J; Starrfelt, Randi

    2017-01-01

    Face and word recognition have traditionally been thought to rely on highly specialised and relatively independent cognitive processes. Some of the strongest evidence for this has come from patients with seemingly category-specific visual perceptual deficits such as pure prosopagnosia, a selective face recognition deficit, and pure alexia, a selective word recognition deficit. Together, the patterns of impaired reading with preserved face recognition and impaired face recognition with preserved reading constitute a double dissociation. The existence of these selective deficits has been questioned over the past decade. It has been suggested that studies describing patients with these pure deficits have failed to measure the supposedly preserved functions using sensitive enough measures, and that if tested using sensitive measurements, all patients with deficits in one visual category would also have deficits in the other. The implications of this would be immense, with most textbooks in cognitive neuropsychology requiring drastic revisions. In order to evaluate the evidence for dissociations, we review studies that specifically investigate whether face or word recognition can be selectively affected by acquired brain injury or developmental disorders. We only include studies published since 2004, as comprehensive reviews of earlier studies are available. Most of the studies assess the supposedly preserved functions using sensitive measurements. We found convincing evidence that reading can be preserved in acquired and developmental prosopagnosia and also evidence (though weaker) that face recognition can be preserved in acquired or developmental dyslexia, suggesting that face and word recognition are at least in part supported by independent processes.

    2016-12-01

    Full Text Available The borderline personality disorder (BPD is characterized by a severe pattern of instability in emotional regulation, interpersonal relationships, identity, and impulse control. These functions are related to the prefrontal cortex (PFC, and since PFC shows a rich anatomical connectivity with the cerebellum, the functionality of the cerebellar-PFC axis may impact on BPD. In this study we investigated the potential involvement of cerebello-thalamo-cortical connections in impulsive reactions through a pre/post stimulation design. BPD patients (n=8 and healthy controls (HC; n=9 performed an Affective Go/No-Go task (AGN assessing information processing biases for positive and negative stimuli before and after repetitive transcranial magnetic stimulation (rTMS; 1 Hz/10 min, 80% RMT over the left lateral cerebellum. The AGN task consisted of four blocks requiring associative capacities of increasing complexity. BPD patients performed significantly worse than the HC, especially when cognitive demands was high (3rd and 4th block, but their performace approached that of HC after rTMS (rTMS was almost ineffective in HC. The more evident effect of rTMS in complex associative tasks might have occurred since the cerebellum is deeply involved in integration and coordination of different stimuli. We hypothesize that, in BPD patients, cerebello-thalamo-cortical communication is altered, resulting in emotional dysregulation and disturbed impulse control. The rTMS over the left cerebellum might have interfered with existing functional connections exerting a facilitating effect on PFC control.

    Unprotected amide protons can undergo fast hydrogen exchange (HX) with protons from the solvent. Generally, NMR experiments using the out-and-back coherence transfer with amide proton detection are affected by fast HX and result in reduced signal intensity. When one of these experiments, 1 H– 15 N HSQC, is used to measure the 15 N transverse relaxation rate (R 2 ), the measured R 2 rate is convoluted with the HX rate (k HX ) and has higher apparent R 2 values. Since the 15 N R 2 measurement is important for analyzing protein backbone dynamics, the HX effect on the R 2 measurement is investigated and described here by multi-exponential signal decay. We demonstrate these effects by performing 15 N R 2 CPMG experiments on α-synuclein, an intrinsically disordered protein, in which the amide protons are exposed to solvent. We show that the HX effect on R 2 CPMG can be extracted by the derived equation. In conclusion, the HX effect may be pulse sequence specific and results from various sources including the J coupling evolution, the change of steady state water proton magnetization, and the D 2 O content in the sample. To avoid the HX effect on the analysis of relaxation data of unprotected amides, it is suggested that NMR experimental conditions insensitive to the HX should be considered or that intrinsic R 2 CPMG values be obtained by methods described herein.

    There has been increased attention on job-related stress and burnout experienced by clinicians working with vulnerable and at-risk populations, including effects on personal mental health, therapeutic decision-making, and job effectiveness. Little is known, however, about the job-related stressors and symptoms of burnout experienced by clinical research staff working with similar populations, especially in terms of moral stress they may experience when adherence to scientific procedures appears to conflict with their personal commitment to address the clinical needs of their research participants or role as health care provider. In this national study, 125 frontline research workers conducting clinical research studies with individuals diagnosed with affective and anxiety disorders completed an online survey including measures assessing research work related moral stress, job burnout, organizational ethics climate and organizational research support. Results indicated that younger research workers, those whose research work was part of a graduate assistantship and perceptions of higher participant research risk were associated with higher levels of moral stress and job burnout. Supportive organizational climates were associated with lower levels of moral stress and job burnout. Recommendations for clinical research workers, supervisors and clinical training directors are discussed.

    Neural models of major depressive disorder (MDD) posit that over-response of components of the brain's salience network (SN) to negative stimuli plays a crucial role in the pathophysiology of MDD. In the present proof-of-concept study, we tested this formulation directly by examining the affective consequences of training depressed persons to down-regulate response of SN nodes to negative material. Ten participants in the real neurofeedback group saw, and attempted to learn to down-regulate, activity from an empirically identified node of the SN. Ten other participants engaged in an equivalent procedure with the exception that they saw SN-node neurofeedback indices from participants in the real neurofeedback group. Before and after scanning, all participants completed tasks assessing emotional responses to negative scenes and to negative and positive self-descriptive adjectives. Compared to participants in the sham-neurofeedback group, from pre- to post-training, participants in the real-neurofeedback group showed a greater decrease in SN-node response to negative stimuli, a greater decrease in self-reported emotional response to negative scenes, and a greater decrease in self-reported emotional response to negative self-descriptive adjectives. Our findings provide support for a neural formulation in which the SN plays a primary role in contributing to negative cognitive biases in MDD. Copyright © 2016 Elsevier Ireland Ltd.

    The borderline personality disorder (BPD) is characterized by a severe pattern of instability in emotional regulation, interpersonal relationships, identity and impulse control. These functions are related to the prefrontal cortex (PFC), and since PFC shows a rich anatomical connectivity with the cerebellum, the functionality of the cerebellar-PFC axis may impact on BPD. In this study, we investigated the potential involvement of cerebello-thalamo-cortical connections in impulsive reactions through a pre/post stimulation design. BPD patients ( n = 8) and healthy controls (HC; n = 9) performed an Affective Go/No-Go task (AGN) assessing information processing biases for positive and negative stimuli before and after repetitive transcranial magnetic stimulation (rTMS; 1 Hz/10 min, 80% resting motor threshold (RMT) over the left lateral cerebellum. The AGN task consisted of four blocks requiring associative capacities of increasing complexity. BPD patients performed significantly worse than the HC, especially when cognitive demands were high (third and fourth block), but their performance approached that of HC after rTMS (rTMS was almost ineffective in HC). The more evident effect of rTMS in complex associative tasks might have occurred since the cerebellum is deeply involved in integration and coordination of different stimuli. We hypothesize that in BPD patients, cerebello-thalamo-cortical communication is altered, resulting in emotional dysregulation and disturbed impulse control. The rTMS over the left cerebellum might have interfered with existing functional connections exerting a facilitating effect on PFC control.

  9. Borderline personality disorder and self-conscious affect: Too much shame but not enough guilt?

    Shame has emerged as a particularly relevant emotion to the maintenance and exacerbation of borderline personality disorder (BPD) features; however, little attention has been paid to the potentially differing effects of other forms of self-conscious affect. While guilt has been demonstrated to have adaptive functions in the social psychology literature, it has not been previously explored whether a lack of socially adaptive guilt might also contribute to BPD-related dysfunction. The present study examined the relationship between BPD features and self-conscious emotions in a sample of undergraduate students (n = 839). Increased shame and decreased guilt independently accounted for significant variance in the association between BPD features and anger, hostility, and externalization of blame. Only increased shame significantly mediated the association between BPD features and anger rumination, and only decreased guilt significantly mediated the relationship between BPD features and aggression. These findings suggest BPD and its associated problems with anger and externalizing may be characterized not only by high levels of shame, but also by lower levels of guilt. Clinical implications include the need to differentiate between self-conscious emotions and teach adaptive responses to warranted guilt. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    A population survey of seasonality in six representative cities in Japan was conducted using the Japanese version of the Seasonal Pattern Assessment Questionnaire (SPAQ). The questionnaires were given to 951 parents (male: female ratio 1:1 age range 34-59 years) of high-school students. Significant regional differences in seasonal variations of mood, length of sleep, and weight were observed; the proportion of individuals reporting high seasonality in the two northern cities was significantly higher than that in the other areas. These results provide evidence for a northern predominance in the prevalence of seasonal affective disorder in Japan.

    Sit-and-wait ambushing and active hunting are two strategies used by predators to capture prey. In snakes, hunting strategy is conserved phylogenetically; most species employ only one strategy. Active hunters encounter and capture more prey but invest more energy in hunting and have higher risks of being predated. This trade-off is important to small predators. The small Cerastes vipera employs both modes of hunting, which is unlike most viperids which use only sit-and wait ambushing. This species hibernates in October and emerges in April. Energy intake should be high prior to hibernation to overcome the non-feeding hibernation period and for reproduction on their emergence. We predicted that more individuals would hunt actively towards hibernation and an abiotic factor would trigger this response. Furthermore, since more energy is required for active hunting, we predicted that snakes in good body condition would use active hunting to a greater extent than snakes in poor body condition. To test our predictions, we tracked free-living snakes year round and determined their hunting strategy, estimated their body condition index (BCI), and calculated circannual parameters of day length as environmental cues known to affect animal behaviour. Two novel findings emerged in this study, namely, hunting strategy was affected significantly by 1) the circannual change in day length and 2) by BCI. The proportion of active hunters increased from 5% in April to over 30% in October and BCI of active foragers was higher than that of sit-and-wait foragers and, therefore, our predictions were supported. The entrainment between the proportion of active hunting and the abiotic factor is indicative of an adaptive function for choosing a hunting strategy. A trend was evident among life stages. When all life stages were present (September-October), the proportion of active foragers increased with age: 0.0% among neonates, 18.2% among juveniles and 31.4% among adults. We concluded that

    The rural inhabitants of the Himalayan region have been exploiting forest resources for their livelihood for generations. The excessive and uncontrolled use of firewood for domestic purposes has ended up with severe deforestation. Therefore, quantification, assessment and restoration of such valuable but exhaustible resources and is imperative their scientific management. The estimates reflect that a total of 88 species are consumed as fuelwood (54 trees and 34 shrubs) by the local people. Fuelwood consumption by 'dhaba' (roadside refreshment establishments) owners (90-120 kg/household/day) was much higher over the common villagers (20-22 kg/household/day). The fuelwood is mainly burnt for cooking, water heating, space heating and lighting, etc. Among these, cooking consumes the fuelwood most. In addition, fuelwood demand increases due to influx of tourists. In the near future, this may also affect the status of the undisturbed forests at the middle elevation. The information in this communication could be utilized for developing various conservation and sustainable strategies in the region to mitigate the impact of forest resource for fodder and fuelwood.

  13. SEASON OF DELTAMETHRIN APPLICATION AFFECTS FLEA AND PLAGUE CONTROL IN WHITE-TAILED PRAIRIE DOG (CYNOMYS LEUCURUS) COLONIES, COLORADO, USA.

    In 2008 and 2009, we evaluated the duration of prophylactic deltamethrin treatments in white-tailed prairie dog ( Cynomys leucurus ) colonies and compared effects of autumn or spring dust application in suppressing flea numbers and plague. Plague occurred before and during our experiment. Overall, flea abundance tended to increase from May or June to September, but it was affected by deltamethrin treatment and plague dynamics. Success in trapping prairie dogs (animals caught/trap days) declined between June and September at all study sites. However, by September trap success on dusted sites (19%; 95% confidence interval [CI] 16-22%) was about 15-fold greater than on undusted control sites (1%; CI 0.3-4%; P≤0.0001). Applying deltamethrin dust as early as 12 mo prior seemed to afford some protection to prairie dogs. Our data showed that dusting even a portion of a prairie dog colony can prolong its persistence despite epizootic plague. Autumn dusting may offer advantages over spring in suppressing overwinter or early-spring flea activity, but timing should be adjusted to precede the annual decline in aboveground activity for hibernating prairie dog species. Large colony complexes or collections of occupied but fragmented habitat may benefit from dusting some sites in spring and others in autumn to maximize flea suppression in a portion of the complex or habitat year-round.

    Full Text Available Abstract Background The DAOA/G30 (D-amino acid oxidase activator gene complex at chromosomal region 13q32-33 is one of the most intriguing susceptibility loci for the major psychiatric disorders, although there is no consensus about the specific risk alleles or haplotypes across studies. Methods In a case-control sample of German descent (affective psychosis: n = 248; controls: n = 188 we examined seven single nucleotide polymorphisms (SNPs around DAOA/G30 (rs3916966, rs1935058, rs2391191, rs1935062, rs947267, rs3918342, and rs9558575 for genetic association in a polydiagnostic approach (ICD 10; Leonhard's classification. Results No single marker showed evidence of overall association with affective disorder neither in ICD10 nor Leonhard's classification. Haplotype analysis revealed no association with recurrent unipolar depression or bipolar disorder according to ICD10, within Leonhard's classification manic-depression was associated with a 3-locus haplotype (rs2391191, rs1935062, and rs3916966; P = 0.022 and monopolar depression with a 5-locus combination at the DAOA/G30 core region (P = 0.036. Conclusion Our data revealed potential evidence for partially overlapping risk haplotypes at the DAOA/G30 locus in Leonhard's affective psychoses, but do not support a common genetic contribution of the DAOA/G30 gene complex to the pathogenesis of affective disorders.

    To examine associations among exercise dependence score, amount of physical activity and eating disorder (ED) symptoms in patients with longstanding ED and non-clinical controls. Adult female inpatients (n = 59) and 53 age-matched controls participated in this cross sectional study. Assessments included the eating disorders examination, eating disorders inventory, exercise dependence scale, reasons for exercise inventory, and MTI Actigraph accelerometer. Positive associations were found among vigorous, not moderate, physical activity, exercise dependence score and ED symptoms in patients. In the controls, ED symptoms were negatively associated with vigorous physical activity and not correlated with exercise dependence score. Exercise for negative affect regulation, not weight/appearance, and amount of vigorous physical activity were explanatory variables for exercise dependence score in both groups. The positive associations among exercise dependence score, vigorous physical activity and ED symptoms need proper attention in the treatment of longstanding ED.

    A detailed visual processing style has been noted in autism spectrum disorder (ASD); this contributes to problems in face processing and has been directly related to abnormal processing of spatial frequencies (SFs). Little is known about the early development of face processing in ASD and the relation with abnormal SF processing. We investigated whether young ASD children show abnormalities in low spatial frequency (LSF, global) and high spatial frequency (HSF, detailed) processing and explored whether these are crucially involved in the early development of face processing. Three- to 4-year-old children with ASD (n = 22) were compared with developmentally delayed children without ASD (n = 17). Spatial frequency processing was studied by recording visual evoked potentials from visual brain areas while children passively viewed gratings (HSF/LSF). In addition, children watched face stimuli with different expressions, filtered to include only HSF or LSF. Enhanced activity in visual brain areas was found in response to HSF versus LSF information in children with ASD, in contrast to control subjects. Furthermore, facial-expression processing was also primarily driven by detail in ASD. Enhanced visual processing of detailed (HSF) information is present early in ASD and occurs for neutral (gratings), as well as for socially relevant stimuli (facial expressions). These data indicate that there is a general abnormality in visual SF processing in early ASD and are in agreement with suggestions that a fast LSF subcortical face processing route might be affected in ASD. This could suggest that abnormal visual processing is causative in the development of social problems in ASD. Copyright © 2010 Society of Biological Psychiatry. Published by Elsevier Inc.

We show that the HX effect on R{sub 2}{sup CPMG} can be extracted by the derived equation. In conclusion, the HX effect may be pulse sequence specific and results from various sources including the J coupling evolution, the change of steady state water proton magnetization, and the D{sub 2}O content in the sample. To avoid the HX effect on the analysis of relaxation data of unprotected amides, it is suggested that NMR experimental conditions insensitive to the HX should be considered or that intrinsic R{sub 2}{sup CPMG} values be obtained by methods described herein.

    To determine how the economy affects psychosocial and socioeconomic treatment outcomes in a cohort of chronic disabling occupational musculoskeletal disorder (CDOMD) patients who completed a functional restoration program (FRP). A cohort of 969 CDOMD patients with active workers' compensation claims completed an FRP (a medically-supervised, quantitatively-directed exercise progression program, with multi-modal disability management). A good economy (GE) group (n = 532) was released to work during a low unemployment period (2005-2007), and a poor economy (PE) group (n = 437) was released during a higher unemployment period (2008-2010). Patients were evaluated upon admission for demographic and psychosocial variables, and were reassessed at discharge. Socioeconomic outcomes, including work return and work retention 1 year post-discharge, were collected. Some significant differences in psychosocial self-report data were found, but most of the effect sizes were small, so caution should be made when interpreting the data. Compared to the PE group, the GE group reported more depressive symptoms and disability at admission, but demonstrated a larger decrease in depressive symptoms and disability and increase in self-reported quality of life at discharge. The PE group had lower rates of work return and retention 1-year after discharge, even after controlling for other factors such as length of disability and admission work status. CDOMD patients who completed an FRP in a PE year were less likely to return to, or retain, work 1-year after discharge, demonstrating that a PE can be an additional barrier to post-discharge work outcomes. A difference in State unemployment rates of <3% (7 vs. 5%) had a disproportionate effect on patients' failure to return to (19 vs. 6%) or retain (28 vs. 15%) work.

    There is a need for theoretically-based research on the motivational processes linked to the adoption and maintenance of an active lifestyle in people with affective disorders. Within the Self-Determination Theory (SDT) framework, we investigated the SDT tenets in people with major depressive disorder or bipolar disorder by examining the factor structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) and by investigating associations between motivation, the Positive and Negative Affect Scale (PANAS) and International Physical Activity Questionnaire (IPAQ) scores. A total of 165 patients (105 ♀) (45.6 ± 14.2 years) agreed to participate. An exploratory factor analysis demonstrated sufficient convergence with the original factor for amotivation, and external and introjected regulation. The items of identified and intrinsic regulation loaded on the same factor, which was labelled autonomous regulation. Significant correlations were found between the total IPAQ score and the subscales amotivation, external regulation, introjected regulation and autonomous regulation. The relative autonomy index (RAI) was associated with the PANAS scores. Differences in RAI were found between physically inactive and active participants. Our results suggest that in people with affective disorders the level of autonomous motivation may play an important role in the adoption and maintenance of health promoting behaviours.

    The evidence on alcohol use disorder among conflict-affected civilian populations remains extremely weak, despite a number of potential risk-factors. The aim of this study is to examine patterns of alcohol use disorder among conflict-affected persons in the Republic of Georgia. A cross-sectional survey of 3600 randomly selected internally displaced persons (IDPs) and former IDPs. Two alcohol use disorder outcomes were measured: (i) having at least hazardous alcohol use (AUDIT score ≥ 8); (ii) episodic heavy drinking (consuming >60 grams of pure alcohol per drinking session at least once a week). Individual level demographic and socio-economic characteristics were also recorded, including mental disorders. Community level alcohol environment characteristics relating to alcohol availability, marketing and pricing were recorded in the respondents' communities and a factor analysis conducted to produce a summary alcohol environment factor score. Logistic regression analyses examined associations between individual and community level factors with the alcohol use disorder outcomes (among men only). Of the total sample, 71% of men and 16% of women were current drinkers. Of the current drinkers (N = 1386), 28% of men and 1% of women were classified as having at least hazardous alcohol use; and 12% of men and 2% of women as episodic heavy drinkers. Individual characteristics significantly associated with both outcomes were age and experiencing a serious injury, while cumulative trauma events and depression were also associated with having at least hazardous alcohol use.

    Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder among fertile women. Studies show reduced quality of life, anxiety, depression, body dissatisfaction, eating disorder, and sexual dysfunction, but the etiology of these disturbs remains still debated. The aim of our study is to verify whether this hyperandrogenic syndrome characterizes a strong psycho(patho)logical personality. Sixty PCOS subjects (mean age 25.8 ± 4.7 years) were evaluated by anthropometric, metabolic, hormonal, clinical, and psychological parameters. After the certainty of the diagnosis of PCOS, the Rorschach test, according to Exner's comprehensive system (CS) and the Millon Clinical Multiaxial Inventory-III (MCMI-III) were administered to each patient. The control group, on which the comparison was carried out, was composed by 40 healthy and aged compared women who were exclusively administered the Rorschach test according to CS. MCMI-III evidenced axis II DSM-IV personality disorders [4.1% schizoid, depressive, sadistic, negativistic (passive-aggressive), and masochistic, 6.1% avoiding, 12.2% dependent, 20.4% histrionic, 16.3% narcissistic, 2.0% obsessive-compulsive], and axis I DSM-IV psychiatric disorders: 10.2% anxiety, 2.0% somatoform disorder and bipolar disorder, 16.3% major depressive disorder. Finally, we found 44.9% delusional disorder and 4.1% thought disorder. Rorschach test's results show 53.1% reduced coping abilities and social skills, 55.1% depression, 30.6% perceptual distortion and cognitive slippage, 24.5% constantly alert and worry, 8.1% at risk for suicide, and finally about 50% of our patients had chronic stress.

    We examined event-contingent recording of daily interpersonal interactions in a diagnostically diverse sample of 101 psychiatric outpatients who were involved in a romantic relationship. We tested whether the unique effect of borderline personality disorder (BPD) symptoms on affective responses (i.e., hostility, sadness, guilt, fear, and positive affect) to perceptions of rejection or acceptance differed with one's romantic partner compared with nonromantic partners. BPD symptoms were associated with more frequent perceptions of rejection and less frequent perceptions of acceptance across the study. For all participants, perceptions of rejecting behavior were associated with higher within-person negative affect and lower within-person positive affect. As predicted, in interactions with romantic partners only, those with high BPD symptoms reported heightened hostility and, to a lesser extent, attenuated sadness in response to perceptions of rejection. BPD symptoms did not moderate associations between perceptions of rejection and guilt, fear, or positive affect across romantic and nonromantic partners. For all participants, perceived acceptance was associated with lower within-person negative affect and higher within-person positive affect. However, BPD symptoms were associated with attenuated positive affect in response to perceptions of accepting behavior in interactions with romantic partners only. BPD symptoms did not moderate associations between perceptions of acceptance and any of the negative affects across romantic and nonromantic partners. This study highlights the specificity of affective responses characteristic of BPD when comparisons are made with patients with other personality and psychiatric disorders. Implications for romantic relationship dysfunction are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Highly hypnotizable individuals have impaired executive function, elevated motor impulsivity and increased emotional sensitivity, which are sometimes found in bipolar disorder patients. It is then reasonable to assume that certain aspects of hypnotic susceptibility differ with the types of bipolar disorder. The Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C) test, the Mood Disorder Questionnaire (MDQ), the Hypomanic Checklist-32 (HCL-32) and the Plutchick-van Praag Depression Inventory (PVP) were applied to 62 patients with bipolar I disorder, 33 bipolar II disorder, and 120 healthy volunteers. The passing rate of the SHSS:C 'Moving hands apart' item was higher in bipolar I patients than in controls, whereas for 'Mosquito hallucination' the rate was lower. Bipolar I and II patients scored significantly higher on MDQ, HCL-32 and PVP scales than controls. The passing rates of 'Mosquito hallucination' in controls, 'Arm rigidity' in bipolar I, and 'Age regression' in bipolar II predicted the respective MDQ scores. In contrast to cognitive suggestions, bipolar I patients followed motor suggestions more often under hypnosis. Furthermore, both bipolar disorder patients and healthy volunteers demonstrated associations between mania levels and certain hypnotic susceptibility features. Our study aids in better understanding the altered conscious states in bipolar disorders, and encourages the use of related psychotherapy for these patients.

    Bipolar disorder is a chronic mood disorder which usually has its onset in adolescence and young adulthood. The disorder is typified by a remitting and relapsing course. While remissions are often partial in nature, relapses are frequent and manifested as manic, mixed, hypomanic and depressive episodes. Rapid cycling is a particularly disabling form of bipolar disorder, characterised by four or more episodes in a 12-month period. Bipolar disorder inevitably causes impairment in social and occupational functioning. Many patients experience severe hopelessness and suicidal ideation and the disorder is associated with one of the highest mortality rates of all psychiatric disorders. The treatment of bipolar depression is particularly challenging and numerous patients achieve incomplete benefit even with complex psychopharmacological strategies. In recent years, many new pharmacological options have become available for the treatment of bipolar depression and the field has seen significant progress. In order to achieve better outcome for the patients, it is mandatory that treating physicians have an up to date knowledge of recent advances in the management of this condition. (author)

    To investigate the characteristics of depressive symptoms and the influence of affective temperament in adults with attention-deficit/hyperactivity disorder (ADHD), in comparison with bipolar disorder (BD) patients and healthy controls (HCs). Sixty patients with ADHD, 50 patients with BD, and 30 HCs were assessed with instruments for measuring depressive symptoms (Beck Depression Inventory-II), and affective temperaments (Temperament Scale of Memphis, Pisa and San Diego, self-administered version; TEMPS-A). In addition, participants were evaluated with scales for measuring ADHD symptoms, impulsiveness, anxiety, executive dysfunction, and quality of life. ADHD patients showed levels of depressive symptoms similar to BD patients and higher than HCs. Only neurovegetative symptoms of depression differentiated ADHD and BD groups (BD > ADHD). Depressive symptoms in ADHD patients correlated positively with core ADHD, impulsivity, anxiety, and dysexecutive symptoms and negatively with quality of life. Thirty-eight percent of patients with ADHD scored above the cutoff for at least one affective temperament. Cyclothymic was the more common affective temperament (25%). ADHD patients with affective temperamental traits were more depressed and impulsive than patients without those traits and showed a symptomatic profile analogous to BD patients. The small size of resultant samples when ADHD group was stratified by the presence of affective temperament. In addition, results may not generalize to less severe ADHD patients from the community. Concomitant depressive symptoms constitute a common occurrence in adults with ADHD that carries significant psychopathological and functional consequences. The concept of affective temperaments may be an interesting link for explaining depressive symptomatology and emotional impulsivity in a subgroup of patients with ADHD, beyond the classic idea of comorbidity.

    We aimed to study the risk of developing post-traumatic stress disorder (PTSD) symptoms in people who resided in an affected area by an extremely severe flood, and sociodemographic risk factors associated with this condition. A geographic information system (GIS) was used to distribute the rainfall data. A case-control study was developed to study the relationship between PTSD and sociodemographic risk factors. To delineate the areas affected by the flood and the intensity of this rainfall in comparison with historical hydrological data, we employed geographical information systems (GIS). Then, we recruited a representative sample of the affected population and another population sample that lived at the time of this disaster in adjacent geographical areas that were not affected. Both groups were randomly selected in primary care practices, from December 1st 2012 to January 31st 2013. All participants, 70 from the affected areas and 91 from the non-affected, filled a sociodemographic questionnaire and the trauma questionnaire (TQ) to identify and rate PTSD symptoms. Our GIS analysis confirmed that the amount of precipitation in 2012 in the areas affected by the flood was exceptionally high compared with historical average rainfall data (461l per square metre vs 265). Individuals who resided in the affected areas at the time of the flood were at much higher risk of developing PTSD symptoms (OR: 8.18; 95% CI: 3.99-17.59) than those living in adjacent, non-affected localities. Among the sociodemographic variables included in this study, only material and financial losses were strongly associated with the onset of PTSD (P disorder, may help develop effective plans to minimize the negative impact of these natural disasters on public health.

    Thought disorder (TD) has been shown to vary in relation to negative affect. Here we examine the role internal source monitoring (iSM, i.e. ability to discriminate between inner speech and verbalized speech) in TD and whether changes in iSM performance are implicated in the affective reactivity effect (deterioration of TD when participants are asked to talk about emotionally-laden topics). Eighty patients diagnosed with schizophrenia-spectrum disorder and thirty healthy controls received interviews that promoted personal disclosure (emotionally salient) and interviews on everyday topics (non-salient) on separate days. During the interviews, participants were tested on iSM, self-reported affect and immediate auditory recall. Patients had more TD, poorer ability to discriminate between inner and verbalized speech, poorer immediate auditory recall and reported more negative affect than controls. Both groups displayed more TD and negative affect in salient interviews but only patients showed poorer performance on iSM. Immediate auditory recall did not change significantly across affective conditions. In patients, the relationship between self-reported negative affect and TD was mediated by deterioration in the ability to discriminate between inner speech and speech that was directed to others and socially shared (performance on the iSM) in both interviews. Furthermore, deterioration in patients' performance on iSM across conditions significantly predicted deterioration in TD across the interviews (affective reactivity of speech). Poor iSM is significantly associated with TD. Negative affect, leading to further impaired iSM, leads to increased TD in patients with psychosis. Avenues for future research as well as clinical implications of these findings are discussed. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

    To describe nursing activities in primary care with patients affected by physical chronic disease and common mental disorders. Patients in primary care who are affected by physical chronic disease and common mental disorders such as anxiety and depression require care and follow-up based on their physical and mental health condition. Primary care nurses are increasingly expected to contribute to the care and follow-up of this growing clientele. However, little is known about the actual activities carried out by primary care nurses in providing this service in the Province of Quebec (Canada). A qualitative descriptive study was conducted. Data were obtained through semistructured individual interviews with 13 nurses practising among patients with physical chronic disease in seven Family Medicine Groups in Quebec (Canada). Participants described five activity domains: assessment of physical and mental health condition, care planning, interprofessional collaboration, therapeutic relationship and health promotion. The full potential of primary care nurses is not always exploited, and some activities could be improved. Evidence for including nurses in collaborative care for patients affected by physical chronic disease and common mental disorders has been shown but is not fully implemented in Family Medicine Groups. Future research should emphasise collaboration among mental health professionals, primary care nurses and family physicians in the care of patients with physical chronic disease and common mental disorders. Primary care nurses would benefit from gaining more knowledge about common mental disorders and from identifying the resources they need to contribute to managing them in an interdisciplinary team. © 2016 John Wiley & Sons Ltd.

    Full Text Available Gökben Hizli Sayar, Gül Eryilmaz, Siban Şemieoğlu, Eylem Özten, Işil Göğcegöz Gül Uskudar University, Neuropsychiatry Istanbul Hospital, Istanbul, Turkey Background: Propofol is often used as an anesthetic agent for electroconvulsive therapy (ECT. In recent studies, propofol was shown to possess significant seizure-shortening properties during ECT. "Valproate" is a mood stabilizer used mainly in the treatment of bipolar affective disorder. It is reported that valproate, being an anticonvulsant, raises the seizure threshold, thus decreases the efficacy of ECT treatment. Aim: The purpose of our study was to compare the dose of propofol in valproate-using patients and valproate-free patients. Methods: In an open design, 17 patients with bipolar affective disorder manic episodes who were to be treated with valproate and ECT in combination, were compared with 16 manic-episode patients who were to be treated with ECT but not valproate. The two groups were compared on the basis of electroencephalography-registered seizure duration and the propofol dosage required to induce anesthesia. Results: Valproate, compared with no valproate treatment, results in a decrease in the propofol dose required to induce anesthesia. In the valproate group of study participants, seizure duration was significantly shorter than in the valproate-free group. Conclusion: The results suggest that valproate reduces the dose of propofol required for anesthesia during ECT treatment in patients with bipolar affective disorder manic episodes. Although propofol is a safe and efficacious anesthetic for ECT treatment, lower doses of propofol should be used to induce anesthesia for patients under valproate treatment. When the clinician needs to prolong seizure duration in patients treated with valproate, interruption of the valproate treatment or an anesthetic agent other than propofol should be considered.

    Genetic factors seem to play an important role in the pathogenesis of affective disorder. The candidate gene strategies are being used, among others, to identify the genes conferring vulnerability to the disease. The genes coding for the receptors of gamma-aminobutyric acid (GABA) have been proposed as candidates for affective disorder, since the GABA neurotransmitter system has been implicated in the pathogenesis of the illness. We examined the possible genetic association between the GABA(A) receptor alpha5 subunit gene locus (GABRA5) on chromosome 15 and affective disorder, in 48 bipolar patients (BP), 40 unipolar patients (UP), and 50 healthy individuals, age- and sex-matched to the patients. All patients and controls were unrelated Greeks. Diagnoses were made after direct interviews according to the DSM-IV and ICD-10 criteria. For the genotyping, a dinucleotide (CA) repeat marker was used. The polymerase chain reaction (PCR) products found were nine alleles with lengths between 272 and 290 base pairs (bp). The distribution of allelic frequencies of the GABRA5 locus differed significantly between BP patients and controls with the 282-bp allele found to be associated with BP affective disorder, while no such difference was observed between the groups of UP patients and controls nor between the two patient groups. The presence or absence of the 282-bp allele in the genotype of BP patients was not shown to influence the age of onset and the overall clinical severity, but was found to be associated with a preponderance of manic over depressive episodes in the course of the illness.

    Full Text Available Abstract Background and Objectives: Musculoskeletal disorders are one of the most common and costly occupational injuries, because they account for one-third of work-related injuries per year. In this study, the factors affecting musculoskeletal disorders, were investigated among hospital emergency nurses of Qom University of Medical Sciences. Methods: This study was performed as a descriptive cross-sectional study using census method on 127 nurses in the Emergency Department of hospitals affiliated to Qom University of Medical Sciences in 2014. The participants completed the Nordic musculoskeletal disorders questionnaire. Data analysis was carried out using Mann-Whitney and the Chi-square Statistical tests. The significance level was considered to be 0.05. Results: In this study, 46 (36.2% participants were men and the remaining were women. The mean age was 33.87±8.892 and the mean work hours per week was 57.71±17.675. The overall prevalence of musculoskeletal disorder was reported to be 82.7%, which had significant relationships with weight, interference with daily work, and pain per day (p0.05. Also, only 16 subjects had participated in ergonomics workshops and 118 subjects were aware of the occupational risks. Conclusion: According to the results of this study and high prevalence of musculoskeletal disorders among nurses, it is suggested that given the type of disorder, change in the way of job performance, adjustment of working hours, holding ergonomics workshops, and preventive measures be placed on the agenda.

    This longitudinal investigation examined the hypothesis that subjective experience during consumption of preferred drugs mediates the association of transmissible risk for substance use disorder (SUD) measured in childhood and adolescence, and SUD diagnosis in adulthood. Transmissible risk denotes the psychological characteristics having intergenerational continuity between parents and their biological children. The transmissible liability index (TLI) was administered to four hundred eighty-three 10 to 12-year-old boys (baseline). Follow-up evaluations were conducted when the boys attained 12-14, 16, 19, and 22 years of age, using age-specific versions of the TLI. Frequency of consumption of the participants' three most preferred drugs, affect on an ordinary day, affect while under influence of the preferred substances, and presence/absence of current SUD were assessed at 22 years of age. Consumption frequency of preferred drugs among boys mediates the association of transmissible risk during childhood, and adolescence and SUD diagnosis in adulthood. Severity of negative affect on a drug-free day predicts frequency of consumption of preferred drugs, which, in turn, predicts severity of negative affect during the drug use event. Neither affect on a drug-free day nor affect during the drug use event mediates the association of transmissible risk and SUD. Affect on drug-free days, and while under influence of preferred substances, covary with consumption frequency; however, affect is not related to transmissible SUD risk or SUD outcome.

    Emotional numbness in individuals affected by posttraumatic stress disorder (PTSD) may be a result of the depletion of emotional capacities. The ability to process emotions in a social context is a part of social cognition, which is still an under-explored topic in PTSD. The present study investigated deficits in social cognition, such as emotion recognition and theory of mind, and their relationship to emotional numbing in 35 military police officers who were in Iraq in April 2006 during a terrorist attack in An-Nasiriyah. Our results indicated that individuals suffering from PTSD showed deficits in social cognition when compared with healthy subjects. These disorders seemed to involve emotional numbing rather than clinical symptoms such as anxiety and depression. Future research directions are suggested to improve the measurement of emotional functioning in PTSD. Copyright © 2011. Published by Elsevier Ireland Ltd.

    The study of language knowledge guided by a purely biological perspective prioritizes the study of syntax. The essential process of syntax is recursion--the ability to generate an infinite array of expressions from a limited set of elements. Researchers working within the biological perspective argue that this ability is possible only because of an innately specified genetic makeup that is specific to human beings. Such a view of language knowledge may be fully justified in discussions on biolinguistics, and in evolutionary biology. However, it is grossly inadequate in understanding language-learning problems, particularly those experienced by children with neurodevelopmental disorders such as developmental dyslexia, Williams syndrome, specific language impairment and autism spectrum disorders. Specifically, syntax-centered definitions of language knowledge completely ignore certain crucial aspects of language learning and use, namely, that language is embedded in a social context; that the role of envrironmental triggering as a learning mechanism is grossly underestimated; that a considerable extent of visuo-spatial information accompanies speech in day-to-day communication; that the developmental process itself lies at the heart of knowledge acquisition; and that there is a tremendous variation in the orthographic systems associated with different languages. All these (socio-cultural) factors can influence the rate and quality of spoken and written language acquisition resulting in much variation in phenotypes associated with disorders known to have a genetic component. Delineation of such phenotypic variability requires inputs from varied disciplines such as neurobiology, neuropsychology, linguistics and communication disorders. In this paper, I discuss published research that questions cognitive modularity and emphasises the role of the environment for understanding linguistic capabilities of children with neuro-developmental disorders. The discussion pertains

    Full Text Available The aim of the study was to evaluate some meat physical quality and muscle fibre properties of rabbit meat when considering 2 sire breeds (SB: Vienna Blue [VB]; Burgundy Fawn [BF]; both coloured and slow-growing breeds, several parity orders (P: 1, 2, ≥3, gender (G, and 2 slaughter seasons (SS: spring, summer in an organic production system. The effect of storage time (ST at frozen state (2 mo at –20°C of Longissimus lumborum (LL meat was also evaluated. Animals were slaughtered when they reached 2.8 kg of live weight. Then, pH and L*a*b* colour values of Biceps femoris (BF and LL muscles, water loss and Warner-Bratzler shear force of LL and hind leg (HL meat, and the fibre typing and enzymatic activity of LL muscle were analysed. LL meat from females showed higher b* values than males (0.04 vs. –1.25; P<0.05. Significant (P<0.05 SB×P, SB×G and P×G interactions were observed for the b* value of LL: VB and BF crossbreds presented a higher b* value when born as P≥3 and P2 respectively, VB females showed higher b* value than VB males, and P2 and P≥3 produced males with a significantly lower b* value. HL thawing losses were significantly (P<0.05 higher in rabbits slaughtered in summer than in those slaughtered in spring, whereas the opposite result was obtained for LL meat (P<0.01. Cooking loss of LL meat was significantly lower in P2 group than P≥3 group (P<0.05. The lactate dehydrogenase activity in LL muscle was higher in VB than in BF crossbreds (930 vs. 830 IU; P<0.05, albeit not supported by differences in fibre type distribution. The ST significantly (P<0.01 reduced pH, a* and b* colour values, and increased lightness of LL meat. It was concluded that the crossbreeds derived from VB and BF genotypes and farmed organically did not show remarkab
