Long-Term Follow-Up of Orally Administered Diacetylmorphine Substitution Treatment

Frick, Ulrich, Rehm, Jürgen, Zullino, Daniele, Fernando, Manrique, Wiesbeck, Gerhard, Ammann, Jeannine, Uchtenhagen, Ambros 11 February 2014 (has links) (PDF)
Background: To assess the long-term course of the feasibility and safety of orally administered heroin [diacetylmorphine (DAM)] tablets in substitution treatment of severely addicted opioid users. Design: Open-label, prospective cohort study with 2 non-randomly assigned treatment arms: DAM tablets only (n = 128) or DAM tablets combined with injected DAM and/or other opioids (n = 237). The average duration of the observation period was 62 months. Study endpoints were the time to discharge from treatment and the number of serious adverse events. Results: Both patient groups had a higher than 70% retention rate after the first 48 months of treatment, with similar long-term retention rates (after 8 years both groups had retention over 50%). The physician-verified rate of serious adverse events was 0.01 events per application year among the exclusively oral substitution group (intention-to-treat analysis) during the last year of observation, and 0.005 events per application year in the other group. Conclusions: Because of their feasibility and safety over years, DAM tablets may be a valuable long-term therapeutic alternative. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Brain responses to odor mixtures with sub-threshold components

Hummel, Thomas, Olgun, Selda, Gerber, Johannes, Huchel, Ursula, Frasnelli, Johannes 06 February 2014 (has links) (PDF)
Although most odorants we encounter in daily life are mixtures of several chemical substances, we still lack significant information on how we perceive and how the brain processes mixtures of odorants. We aimed to investigate the processing of odor mixtures using behavioral measures and functional magnetic resonance imaging (fMRI). The odor mixture contained a target odor (ambroxan) in a concentration at which it could be perceived by half of the subjects (sensitive group); the other half could not perceive the odor (insensitive group). In line with previous findings on multi-component odor mixtures, both groups of subjects were not able to distinguish a complex odor mixture containing or not containing the target odor. However, sensitive subjects had stronger activations than insensitive subjects in chemosensory processing areas such as the insula when exposed to the mixture containing the target odor. Furthermore, the sensitive group exhibited larger brain activations when presented with the odor mixture containing the target odor compared to the odor mixture without the target odor; this difference was smaller, though present for the insensitive group. In conclusion, we show that a target odor presented within a mixture of odors can influence brain activations although on a psychophysical level subjects are not able to distinguish the mixture with and without the target. On the practical side these results suggest that the addition of a certain compound to a mixture of odors may not be detected on a cognitive level; however, this additional odor may significantly change the cerebral processing of this mixture. In this context, FMRI offers unique possibilities to look at the subliminal effects of odors.

Erythrophobie: Störungswissen und Verhaltenstherapie / Fear of Blushing: The Disorder and Its Cognitive-Behavioural Therapy

Chaker, Samia, Hoyer, Jürgen 10 February 2014 (has links) (PDF)
Erythrophobie wird als klinische Bezeichnung für die Angst zu erröten verwendet, wenn das Einzelsymptom Erröten im Vordergrund einer Angstproblematik steht. Die vorliegende Übersicht beruht auf einer umfangreichen Literaturrecherche und wird ergänzt durch eigene klinische Beobachtungen aus einer Pilotstudie zur kognitiv-behavioralen Gruppentherapie der Errötungsangst. Wir referieren den aktuellen Kenntnisstand zu Erythrophobie in Bezug auf die differentialdiagnostische Einordnung, auf ätiologische und pathogenetische Konzepte sowie auf die Verhaltenstherapie der Störung. Insgesamt zeigt die Übersicht, dass Erythrophobie am sinnvollsten als Subsyndrom der Sozialen Phobie beschrieben werden kann. Patienten mit Errötungsangst als Hauptbeschwerde unterscheiden sich jedoch von anderen Patienten mit Sozialer Phobie im Hinblick auf Behandlungsanliegen, Inanspruchnahmeverhalten, Behandlungserwartung und Therapieziele sowie durch spezifische aufrechterhaltende Mechanismen der Störung, insbesondere durch eine übertriebene und inflexible Aufmerksamkeitsfokussierung auf körperliche Symptome. Der Einsatz eines Aufmerksamkeitstrainings als spezifisches Behandlungsmodul bei Errötungsangst ist vielversprechend und sollte in bekannte Ansätze zur Therapie der Sozialen Phobie integriert werden. Abschließend werden Impulse für weiterführende Forschungsaktivitäten skizziert. / Erythrophobia is the pathological form of fear of blushing. This review is based upon an extensive literature research and supplemented by clinical observations from a pilot study of a cognitive-behavioural group therapy for fear of blushing. Current knowledge about fear of blushing is reported regarding diagnostic considerations, aetiologic and pathogenetic mechanisms, and cognitive-behavioural therapy. In conclusion, this review indicates that fear of blushing should be classified as a sub-syndrome of social phobia. Patients suffering from fear of blushing as predominant complaint differ from other patients with social phobia in health-care utilisation, treatment expectation and treatment goals. However, the most prominent difference lies in the exaggerated and inflexible self-focused attention these patients direct to their arousal and bodily symptoms. Therefore, attention training as a specific treatment unit is promising and should be integrated in standard treatment approaches for social phobia. Finally, options for further research are outlined. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw. Nationallizenz frei zugänglich.

Ein Interview zur Erfassung sozialer Ängste unter Einbeziehung von Körpersymptomen

Chaker, Samia, Haustein, Elisa, Hoyer, Jürgen, Davidson, Jonathan R.T. 07 February 2014 (has links) (PDF)
Die Brief Social Phobia Scale – German version (BSPS-G) ist ein Kurzinterview zum Screening sozialer Ängste. Dabei werden Schwere oder Verlauf einer bereits diagnostizierten sozialen Angststörung erfasst. Im Folgenden wird der Hintergrund dargelegt und eine Kurzbeschreibung des englischsprachigen Originals (BSPS) gegeben: Die soziale Phobie ist gekennzeichnet durch ausgeprägte und anhaltende Angst, sich in sozialen oder Leistungssituationen peinlich zu verhalten, gedemütigt zu werden oder bestimmte Körpersymptome zu zeigen (Diagnostisches und Statistisches Manual psychischer Störungen, DSM-IV-TR [Saß et al., 2003]). Die Prävalenzraten liegen zwischen 6,7% [Fehm et al., 2005] und 12,1% [Kessler et al., 2005] und bei bis zu 25% für subklinische Ängste, die in Schwere und Beeinträchtigung häufig dem Vollbild ähnlich sind [Beesdo et al., 2007; Knappe et al., 2009]. Zur diagnostischen Erfassung der sozialen Phobie liegen zahlreiche Selbsteinschätzungsverfahren vor, aber kaum Fremdbeurteilungsverfahren [Mitte et al., 2007]. Als Interviewverfahren hat sich die Liebowitz Skala (Liebowitz Soziale Angst Skala, LSAS) [Stangier und Heidenreich, 2005] etabliert. Die BSPS hat demgegenüber die Vorteile, dass sie viel ökonomischer ist und explizit typische Körpersymptome erfasst, die soziale Ängste sowohl begleiten als auch auslösen können. Die Validierung der englischsprachigen Originalversion der BSPS zeigte sehr gute Kennwerte für die Test-Retest-Reliabilität (rtt = 0,91) und die interne Konsistenz (Cronbachs α = 0,82) sowie gute konvergente und diskriminante Validität und Änderungssensitivität. Als Cut-Off-Wert wurde ein Summenwert von 20 Punkten bestimmt [Davidson et al., 1997]. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Instructions matter: a comparison of baseline conditions for cognitive emotion regulation paradigms

Diers, Kersten, Weber, Fanny, Brocke, Burkhard, Strobel, Alexander, Schönfeld, Sabine 15 July 2014 (has links) (PDF)
The choice of a meaningful baseline condition is a crucial issue for each experimental design. In the case of cognitive emotion regulation, it is common to either let participants passively view emotional stimuli without any further specific instructions or to instruct them to actively attend to and permit any arising emotions, and to contrast one of these baseline conditions with a regulation condition. While the “view” strategy can be assumed to allow for a more spontaneous emotional response, the “permit” strategy may result in a more pronounced affective and cognitive response. As these conceptual differences may be associated with differences both in subjective emotional experience and neural activation, we compared these two common control conditions within a single functional magnetic resonance imaging (fMRI) experiment, during which participants were instructed to either passively view a set of unpleasant and neutral pictures or to actively permit any emotions arising in response to the unpleasant pictures. Trial-by-trial ratings confirmed that participants perceived the unpleasant pictures as more arousing than the neutral pictures, but also indicated higher subjective arousal during the “permit negative” as compared to the “view negative” and “view neutral” conditions. While both the “permit negative” and “view negative” conditions led to increased activation of the bilateral amygdala when contrasted with the passive viewing of neutral pictures, activation in the left amygdala was increased in response to the “permit” instruction as compared to the “view” instruction for unpleasant pictures. The increase in amygdala activation in both the “permit” and “view” conditions renders both strategies as suitable baseline conditions for studies of cognitive emotion regulation. Conceptual and activation differences, however, indicate that these two variants are not exchangeable and should be chosen depending on the experimental context.

Worry Exposure versus Applied Relaxation in the Treatment of Generalized Anxiety Disorder

Hoyer, Jürgen, Beesdo, Katja, Gloster, Andrew T., Runge, Juliane, Höfler, Michael, Becker, Eni S. 13 February 2014 (has links) (PDF)
Background: Worry exposure (WE) is a core element of cognitive-behavioral treatment for generalized anxiety disorder (GAD). Its efficacy as a stand-alone treatment method (without further cognitive-behavioral therapy interventions) has never been tested.We aimed to examine whether WE alone is as efficacious as the empirically supported stand-alone treatment for GAD, applied relaxation (AR). Methods: In a randomized controlled study, 73 outpatients meeting DSM-IV criteria for GAD as primary diagnosis were allocated to either WE or AR or a waiting list control group; in a 2nd randomization procedure the waiting list subjects were reallocated to WE or AR. The treatment was manualized (15 sessions with WE or AR), included 6-month and 1-year follow-ups, as well as last observation carried forward and completer analyses, and was controlled for allegiance effects.The Hamilton Anxiety Rating Scale and the State-Trait Anxiety Scale were used as primary outcome measures. Self-report scales of anxiety, worrying and depression including negative metacognition about worrying and thought suppression served as secondary outcome measures. Results: The dropout rate was moderate. The pre-/posttreatment effects were high for the Hamilton Anxiety Rating Scale (standardized mean difference >1) and for the State-Trait Anxiety Inventory (standardized mean difference >0.87). The proportion of patients reaching high end state functioning was 48% (WE) and 56% (AR). WE and AR did not differ with regard to dropout rate or treatment effects. The treatment effects were stable at 6 month and 1 year follow-up. Conclusion: This is the first study to show that a stand-alone exposure in sensu technique – WE – is efficacious in the treatment of GAD. Both AR and WE seem to represent effective principles of change in GAD. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Mentalizing Language Development in a Longitudinal Attachment Sample: Implications for Alexithymia

Lemche, Erwin, Klann-Delius, Gisela, Koch, Rainer, Joraschky, Peter 13 February 2014 (has links) (PDF)
Background: The construct of alexithymia implies a deficit in symbolization for emotional, somatic, and mental states. However, the etiologic factors for alexithymia have not yet been fully elucidated. The present study investigated the use of mentalizing language, i.e. the utterance of internal states, from a developmental perspective according to attachment organization and disorganization. Methods: A longitudinal design across 4 time points was applied to a volunteer sample of 42 children. At 12 months, children were tested with the strange situation procedure, the standard measure of attachment at the optimal age, and attachment classifications were taken of videotapes. At ages 17, 23, 30 and 36 months, mother and child were observed in simplified separation episodes of 30 min duration. Transcripts of the sessions were subject to coding of internal state words. Results: During the investigated span, securely attached children rapidly acquired emotion, physiology, cognition and emotion-regulatory language, whereas insecurely attached and disorganized children either completely lacked internal state language or displayed a considerable time lag in the use of emotion and cognition vocabulary. Conclusion: The results raise the possibility that alexithymia might be a consequence of deficits in the development of internal state language in the context of insecure or disorganized childhood attachment relationships. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Changes in Conflict, Symptoms, and Well-Being during Psychodynamic and Cognitive-Behavioral Alcohol Inpatient Treatment

Hoyer, Jürgen, Fecht, Jens, Lauterbach, Wolfgang, Schneider, Ralf 13 February 2014 (has links) (PDF)
Background: According to Grawe’s psychological therapy approach, conflict reduction can be expected not only in psychodynamic, but also in cognitive-behavioral therapy (CBT). This was tested in an effectiveness study. Changes in cognitive conflicts, along with those of symptom severity and well-being were analyzed during alcohol inpatient treatment. Methods: Four times during treatment, groups of patients receiving psychodynamic therapy (n = 45 patients) or CBT (n = 49 patients) were measured and compared. Lauterbach’s Online Conflict Test was used to measure conflict. Symptom severity and well-being were measured using questionnaires. Results: Results showed significant conflict decrease in both groups with a tendency towards faster reduction under CBT. There was also significant change in symptom severity and well-being in both groups with no difference regarding reduction gradient. Moreover, patients in the psychodynamic treatment group exhibited lower symptom scores at treatment begin which may be a consequence of clinical group assignment. Conclusions: In general, the findings confirmed Grawe’s theoretical assumptions. Generalizability to other diagnostic groups and other clinical settings remains to be tested. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Lithium’s Emerging Role in the Treatment of Refractory Major Depressive Episodes: Augmentation of Antidepressants

Bauer, Michael, Adli, Mazda, Bschor, Tom, Pilhatsch, Maximilian, Pfennig, Andrea, Sasse, Johanna, Schmid, Rita, Lewitzka, Ute 20 February 2014 (has links) (PDF)
Background: The late onset of therapeutic response and a relatively large proportion of nonresponders to antidepressants remain major concerns in clinical practice. Therefore, there is a critical need for effective medication strategies that augment treatment with antidepressants. Methods: To review the available evidence on the use of lithium as an augmentation strategy to treat depressive episodes. Results: More than 30 open-label studies and 10 placebo-controlled double-blind trials have demonstrated substantial efficacy of lithium augmentation in the acute treatment of depressive episodes. Most of these studies were performed in unipolar depression and included all major classes of antidepressants, however mostly tricyclics. A meta-analysis including 10 randomized placebo-controlled trials has provided evidence that lithium augmentation has a statistically significant effect on the response rate compared to placebo with an odds ratio of 3.11, which corresponds to a number-needed-to-treat of 5. The meta-analysis revealed a mean response rate of 41.2% in the lithium group and 14.4% in the placebo group. One placebo-controlled trial in the continuation treatment phase showed that responders to acute-phase lithium augmentation should be maintained on the lithium-antidepressant combination for at least 12 months to prevent early relapses. Preliminary studies to assess genetic influences on response probability to lithium augmentation have suggested a predictive role of the –50T/C single nucleotide polymorphism of the GSK3β gene. Conclusion: Augmentation of antidepressants with lithium is currently the best-evidenced augmentation therapy in the treatment of depressed patients who do not respond to antidepressants. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Lithium Reduces Pathological Aggression and Suicidality: A Mini-Review

Müller-Oerlinghausen, Bruno, Lewitzka, Ute 20 February 2014 (has links) (PDF)
From a practical point of view, the well-proven antisuicidal and anti-aggressive effects of lithium are of utmost importance for a rational, safe and economical treatment of patients with affective disorders. Regular lithium long-term treatment reduces the otherwise 2- to 3-fold increased mortality of untreated patients with severe affective disorders down to the level of the general population. This is mainly due to the reduced suicide risk. Many international studies have confirmed this fascinating property of lithium which so far has not been demonstrated with comparable evidence for any other psychotropic compound. The antisuicidal effects of lithium might possibly be related to its anti-aggressive effects which have been shown in various species, populations and settings, such as animals, inhabitants of nursing homes for the elderly, mentally handicapped subjects, children and adolescents with hyperactive, hostile and aggressive behavior, and particularly in hyperaggressive inmates of correction units and prisons. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.
