Abstract
BACKGROUND In light of the dynamic COVID-19 pandemic, the exposure to pandemic-related media coverage may change over time and may be particularly relevant due to associations with psychopathological symptoms. The aims of the present study were to examine changes in media consumption over time and to analyze its prospective associations with psychological strain. METHOD The study uses a longitudinal observational design with ten periods of online data collection from March 2020 to April 2022 in an adult convenience sample (N = 8337) of the general population in Germany. RESULTS Our data revealed that the frequency and duration of pandemic-related media exposure as well as their subjective critical evaluation showed the highest levels at the beginning of the pandemic and peaked again in autumn 2020 and spring 2021. The primarily used media formats changed only slightly over time. The amount of media exposure at baseline was associated with more impairing pandemic-related anxiety 1 month, 1 year, and 2 years later. CONCLUSION Our results hint to potentially problematical and long-lasting associations of pandemic-related media consumption with mental strain. Our findings could serve as an orientation for recommendations, further research, and adequate interventions for a responsible dealing with media coverage.

Advising activity-knowledge, attitudes, beliefs, and behaviors regarding the recommendation of physical activity in clinical psychologists. Eur Arch Psychiatry Clin Neurosci 2024:10.1007/s00406-024-01819-7. [PMID: 38714563 DOI: 10.1007/s00406-024-01819-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 04/19/2024] [Indexed: 05/10/2024]
Abstract
BACKGROUND Regular physical activity comes with multiple benefits for physical but also mental health and can be a pivotal element in the prevention and treatment of mental disorders. Clinical psychologists play an important role in supporting their patients in increasing physical activity levels. Up to date, there is only little research on recommendation of physical activity in psychologists worldwide and no such research for psychologists in Germany. Aim of this study was to assess knowledge, attitudes, beliefs and behaviors regarding physical activity in psychologists in Germany. METHODS We assessed knowledge, attitudes, beliefs and behaviors regarding physical activity among a sample of clinical psychologists in Germany using the "Exercise in Mental Illness Questionnaire-German" (EMIQ-G) in a cross-sectional online survey. RESULTS 454 participants were included in the analysis. Participants reported moderate levels of knowledge and self-confidence in recommending physical activity. Only 14% of the participants received formal training regarding physical activity recommendation. Most participants recommended physical activity to their patients, primarily through personal discussions and referrals to exercise professionals. About one third did not give any recommendations regarding intensity. Strength training was only recommended by a minority. CONCLUSION There is a need for greater integration of information and instructions regarding the recommendation of physical activity in the treatment of people with mental disorders in the training and further education of psychologists.

[Non-response to psychotherapy: concepts, problems and referral options]. DER NERVENARZT 2024; 95:440-447. [PMID: 38480532 DOI: 10.1007/s00115-024-01633-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 02/09/2024] [Indexed: 05/04/2024]
Abstract
AIM In this paper we review the current literature on the clinical problem that some patients do not achieve response after adequately conducted psychotherapy. We explicate our understanding of nonresponse and treatment resistance including the operational definitions, summarize the theoretical explanations and empirical studies and put forward possible study designs and treatment options. METHODS Literature search using PubMed and Web of Science. RESULTS For the domain of psychotherapy, the term treatment resistance does not seem appropriate; instead, we use the more descriptive terms nonresponse and recurrent nonresponse. Generally, this topic is far less represented in psychotherapy than in pharmacotherapy. Controlled switching studies with a switch from pharmacotherapy to psychotherapy are rare and those switching from one psychotherapeutic approach to another are nearly nonexistent. Building on clinical considerations, we propose a flow-chart for clinical decision making after nonresponse in psychotherapy. DISCUSSION Learning from errors is highly beneficial. This principle should be more consistently followed up in psychotherapy research as well as in supervision and training. Guidelines should include consensual and evidence-based advice on how to deal with nonresponse and recurring nonresponse.

Step away from depression-results from a multicenter randomized clinical trial with a pedometer intervention during and after inpatient treatment of depression. Eur Arch Psychiatry Clin Neurosci 2024; 274:709-721.

Abstract
Evidence for the effectiveness of physical activity (PA) in the treatment of depression prevails for outpatients with mild and moderate symptom levels. For inpatient treatment of severe depression, evidence-based effectiveness exists only for structured and supervised group PA interventions. The Step Away from Depression (SAD) study investigated the effectiveness of an individual pedometer intervention (PI) combined with an activity diary added to inpatient treatment as usual (TAU). In this multicenter randomized controlled trial, 192 patients were randomized to TAU or TAU plus PI. The two primary outcomes at discharge were depression-blindly rated with the Montgomery-Åsberg Depression Rating Scale (MADRS)-and average number of daily steps measured by accelerometers. Secondary outcomes were self-rated depression and PA, anxiety, remission and response rates. Multivariate analysis of variance (MANOVA) revealed no significant difference between both groups for depression and daily steps. Mean MADRS scores at baseline were 29.5 (SD = 8.3) for PI + TAU and 28.8 (SD = 8.1) for TAU and 16.4 (SD = 10.3) and 17.2 (SD = 9.9) at discharge, respectively. Daily steps rose from 6285 (SD = 2321) for PI + TAU and 6182 (SD = 2290) for TAU to 7248 (SD = 2939) and 7325 (SD = 3357). No differences emerged between groups in secondary outcomes. For severely depressed inpatients, a PI without supervision or further psychological interventions is not effective. Monitoring, social reinforcement and motivational strategies should be incorporated in PA interventions for this population to reach effectiveness.

Exercise as Treatment for "Stress-Related" Mental Disorders. Curr Neuropharmacol 2024; 22:420-436. [PMID: 37779399 PMCID: PMC10845075 DOI: 10.2174/1570159x22666230927103308] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 03/29/2023] [Accepted: 04/02/2023] [Indexed: 10/03/2023] Open
Abstract
The beneficial impact of physical activity on preventing and treating mental disorders has captured growing (research) interest. This article aims to provide a concise overview of essential evidence regarding the effectiveness and underlying mechanisms of physical activity for individuals with mental disorders clustered as "stress-related" conditions. Empirical findings (e.g., longitudinalprospective studies, interventional randomized-controlled-trials, reviews, meta-analyses) regarding the effects of physical activity in the prevention and treatment of stress-related mental disorders are summarized. Furthermore, potential mechanisms underlying these effects are discussed, and recommendations regarding the use of physical activity are outlined. The majority of studies indicate good efficacy of physical activity in prospectively lowering the risk for the incidence of subsequent stress-related mental disorders as well as in the treatment of manifest disorders. Most evidence targets unipolar depressive disorder and, secondly, anxiety disorders. Research regarding posttraumatic stress disorder, obsessive-compulsive disorders, and somatoform disorders is promising but scarce. Physical activity seems to be useful as a stand-alone-treatment as well as in combination with other psychotherapeutic or pharmacological treatments. Multiple intertwined physiological, psychological, and social mechanisms are assumed to mediate the beneficial effects. Recommendations regarding physical activity can orientate on official guidelines but should consider the individual needs and circumstances of each subject. In summary, physical activity seems to be effective in the prevention and treatment of stressrelated mental disorders and, therefore, should be fostered in healthcare-settings. Future studies are needed to clarify partly inconsistent patterns of results and to close research gaps, e.g., concerning somatoform disorders.

Illness anxiety predicts higher mental strain and vaccine willingness-A nine-wave longitudinal study during the first 1.5 years of the COVID-19 pandemic in Germany. Stress Health 2023; 39:1137-1147. [PMID: 37158010 DOI: 10.1002/smi.3255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 04/02/2023] [Accepted: 04/23/2023] [Indexed: 05/10/2023]
Abstract
Illness anxiety may amplify vulnerability to psychopathological symptoms during the COVID-19-pandemic-perhaps especially at the beginning of the pandemic and during high infection waves, but empirical evidence on this is lacking. In addition, considering a potentially functional facet of it, illness anxiety might be associated with higher vaccine willingness. We analyzed data of a nine-wave longitudinal online-survey (March 2020-October 2021) with 8148 non-probability sampled adults of the general population in Germany (clinicaltrials.gov: NCT04331106). Using multilevel analysis, we investigated longitudinal associations of dimensionally assessed illness anxiety (worry about illness, bodily preoccupation) with mental strain and vaccine willingness and considered the dynamic of the pandemic (i.e., duration and infection rates). Higher worry about illness and bodily preoccupation were associated with higher COVID-19-related fears, unspecific anxiety, depressive symptoms, and vaccine willingness. Vaccine willingness increased over time and in parallel to higher infection rates. Symptoms of mental strain decreased with continuing duration of the pandemic but increased when infection rates inclined. This decrease and increase, respectively, was steeper in individuals with higher illness anxiety. Our findings suggest that individuals with higher illness anxiety are more vulnerable to experience psychopathological symptoms during the ongoing pandemic, particularly at its beginning and during times of high infection rates. Thus, illness anxiety and associated symptoms should be targeted by adaptive measures. The fluctuation of symptoms parallel to the pandemic situation implies that support should be particularly issued at the beginning of extraordinary situations as well as during phases of high infection rates.

Abstract
Zusammenfassung
Hintergrund
Die COVID-19-Pandemie geht potenziell mit zahlreichen Veränderungen im Leben der Allgemeinbevölkerung einher. Dennoch gibt es bisher kaum Befunde dazu, welche Auswirkungen als besonders gravierend und negativ erlebt wurden, wie sich diese Auswirkungen und ihre Bewertungen im Verlauf der Pandemie änderten, und welche Unterstützungswünsche in diesem Kontext entstanden.
Methode
Längsschnittliche Daten einer Onlinestudie mit 10 Messzeitpunkten über die ersten 2 Jahre der Pandemie (März 2020 bis April 2022) wurden in einer Mixed-methods-Analyse betrachtet. Die Stichprobe aus 8337 Erwachsenen der Allgemeinbevölkerung in Deutschland beantwortete qualitative Freitextfragen zu den gravierendsten Konsequenzen der Pandemie auf ihr Leben sowie Unterstützungswünschen. Quantitativ wurden zudem die Bewertung der Konsequenzen im Pandemieverlauf und ihre Assoziationen mit psychischer Belastung betrachtet.
Ergebnisse
Die erlebten Konsequenzen und insbesondere ihre Bewertung veränderten sich im Pandemieverlauf. Sozial-gesellschaftliche und das allgemeine Leben betreffende Konsequenzen wurden im Schnitt besonders gravierend und negativ erlebt. Negativer erlebte Konsequenzen waren quer- und teilweise auch längsschnittlich mit stärkeren Angst- und depressiven Symptomen assoziiert. Psychotherapeutische sowie evaluativ-kommunikative Unterstützung wurde im Pandemiekontext besonders häufig erbeten.
Schlussfolgerungen
Subjektiv negativ erlebte Konsequenzen sollten möglichst durch adäquate Maßnahmen abgemildert werden. Die dynamischen Veränderungen der Konsequenzen und damit auch des Unterstützungsbedarfs im Pandemieverlauf sollten berücksichtigt werden. Die Unterstützungsmöglichkeiten reichen von sehr niedrigschwelligen Angeboten (z. B. Tipps online) bis hin zu einer Psychotherapie.

Abstract
Sports psychiatry and psychotherapy is a relatively young field and is comprised of two key segments: the special features of the diagnostics and therapy of mental disorders in elite athletes and the use of exercise and sports in the development and treatment of mental disorders. Although all mental disorders can in principle also occur in (elite) athletes, there are additionally sport-specific mental disorders, such as anorexia athletica and other eating disorders, chronic traumatic encephalopathy, misuse of and dependency on performance-enhancing substances (doping) and muscle dysmorphia. Many high-quality clinical trials over the past two decades have been able to demonstrate a therapeutic efficacy of physical activity and sport in the treatment of various mental disorders. All clinicians active in psychiatry and psychotherapy should possess a basic knowledge of sports psychiatry.

Mental Health in German Paralympic Athletes During the 1st Year of the COVID-19 Pandemic Compared to a General Population Sample. Front Sports Act Living 2022; 4:870692. [PMID: 35498519 PMCID: PMC9047049 DOI: 10.3389/fspor.2022.870692] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Accepted: 03/16/2022] [Indexed: 11/13/2022] Open
Abstract
Introduction The COVID-19 pandemic has huge influences on daily life and is not only associated with physical but also with major psychological impacts. Mental health problems and disorders are frequently present in elite paralympic athletes. Due to the pandemic situation, new stressors (e.g., loss of routine, financial insecurity) might act upon the athletes. Therefore, the assessment of mental health in athletes during the COVID-19 pandemic is important to identify prevalence of psychological problems and propose countermeasures. Methods The mental health of German paralympic athletes was longitudinally monitored (starting in May 2019). The athletes completed the Patient Health Questionnaire 4 (PHQ-4) on a weekly basis and reported a stress level, training hours, and training load. During the pandemic, 8 measurement time points (March 2020 to April 2021) were used to reflect the psychological health course of the athletes. In parallel, a convenience sample of the general population was questioned about their psychological distress, including the PHQ-4. To be included in the analysis, participants of both groups had to complete at least 4 measurement time points. Matching of the para-athletes and the general population sample was prioritized upon completion of the same measurement time points, gender, and age. Results Seventy-eight paralympic athletes (40 women, 38 men, age: 29.8 ± 11.4 years) met the inclusion criteria. Seventy-eight matched pairs of the general population (40 women; 38 men; age: 30.5 ± 10.9 years) were identified. The para-athletes had a significantly (p <0.0001; 0.39 < r <0.48) lower PHQ-4 value at each measurement time point compared to the matched control group. No significant age or sex differences were evident regarding the symptom burden. In para-athletes, no significant and a weak positive correlation was found between decreased training load and PHQ-4 values and a stress level, respectively. Reduced physical activity was significantly (p <0.0001) associated with higher PHQ-4 values in the general population sample. Discussion Lower PHQ-4 values were reported by the para-athletes compared to the general population sample. However, small sample sizes must be considered while interpreting the data. Nevertheless, adequate support for individuals suffering from severe psychopathological symptoms should be provided for para-athletes as well as for the general population.

Efficacy of temporally intensified exposure for anxiety disorders: A multicenter randomized clinical trial. Depress Anxiety 2021; 38:1169-1181. [PMID: 34293223 DOI: 10.1002/da.23204] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 06/25/2021] [Accepted: 07/12/2021] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND The need to optimize exposure treatments for anxiety disorders may be addressed by temporally intensified exposure sessions. Effects on symptom reduction and public health benefits should be examined across different anxiety disorders with comorbid conditions. METHODS This multicenter randomized controlled trial compared two variants of prediction error-based exposure therapy (PeEx) in various anxiety disorders (both 12 sessions + 2 booster sessions, 100 min/session): temporally intensified exposure (PeEx-I) with exposure sessions condensed to 2 weeks (n = 358) and standard nonintensified exposure (PeEx-S) with weekly exposure sessions (n = 368). Primary outcomes were anxiety symptoms (pre, post, and 6-months follow-up). Secondary outcomes were global severity (across sessions), quality of life, disability days, and comorbid depression. RESULTS Both treatments resulted in substantial improvements at post (PeEx-I: dwithin = 1.50, PeEx-S: dwithin = 1.78) and follow-up (PeEx-I: dwithin = 2.34; PeEx-S: dwithin = 2.03). Both groups showed formally equivalent symptom reduction at post and follow-up. However, time until response during treatment was 32% shorter in PeEx-I (median = 68 days) than PeEx-S (108 days; TRPeEx-I = 0.68). Interestingly, drop-out rates were lower during intensified exposure. PeEx-I was also superior in reducing disability days and improving quality of life at follow-up without increasing relapse. CONCLUSIONS Both treatment variants focusing on the transdiagnostic exposure-based violation of threat beliefs were effective in reducing symptom severity and disability in severe anxiety disorders. Temporally intensified exposure resulted in faster treatment response with substantial public health benefits and lower drop-out during the exposure phase, without higher relapse. Clinicians can expect better or at least comparable outcomes when delivering exposure in a temporally intensified manner.

Abstract
Resting state alpha power asymmetry in frontal and temporal regions has been reported in various clinical populations, possibly indicating deficits in prefrontal control. In panic disorder (PD), results regarding alpha asymmetric activity to date have been mixed. This study compared 55 PD patients and 42 healthy controls (HC) with regards to resting state alpha power asymmetry. Our results show more right-than-left fronto-lateral alpha power in PD, whereas at other sites and in HC no significant differences were detected. These results support the notion of altered neurobiological processes in PD that possibly represent a vulnerability to the experience of panic attacks. Further studies are needed to clarify potential causal implications of this finding in the genesis of PD, as well as to specify the functional significance of fronto-lateral alpha power asymmetry in PD.

Abstract
BACKGROUND Epidemics and pandemics and the measures taken to contain their spread are accompanied by numerous stressors, which can lead in particular to severe anxiety. OBJECTIVE This article describes the components and determinants of these anxiety symptoms, potential resilience and risk factors and appropriate recommendations for action. METHODS The article presents an overview of research results regarding COVID-19 and previous epidemics and pandemics (e.g., HIV, SARS, MERS, Ebola and swine flu). Furthermore, official recommendations for action are presented. RESULTS Anxiety symptoms frequently occur in epidemics and pandemics, especially in the early phase and usually decrease in the further course. Although other aspects of different infectious diseases vary, the associated fears are similar and include e.g. the fear of health-related, social and economic consequences. Resilience and risk factors in various epidemics and pandemics are comparable. Self-efficacy expectation, tolerance of uncertainty, normalization, routines, safety and social support usually have a protective effect. In contrast, excessive media consumption, female gender, work in a medical context, suppression, pre-existing diseases, unhealthy behavior and closer exposure to the virus are often accompanied by more severe anxiety. CONCLUSION Fears should be observed and addressed in order to reduce pathological processes, especially in vulnerable groups. It is advisable to promote resilience factors and to counteract risk factors with preventive and therapeutic measures. For this purpose, the development and empirical testing of specific interventions as well as further longitudinal studies are needed.

Longitudinal changes of anxiety and depressive symptoms during the COVID-19 pandemic in Germany: The role of pre-existing anxiety, depressive, and other mental disorders. J Anxiety Disord 2021; 79:102377.

Abstract
Especially individuals with mental disorders might experience an escalation of psychopathological symptoms during the COVID-19 pandemic. Therefore, we investigated the role of anxiety, depressive, and other mental disorders for levels and longitudinal changes of COVID-19-related fear, anxiety and depressive symptoms during the first months of the COVID-19 pandemic in Germany. In a longitudinal observational design with four assessment waves from March, 27th until June, 15th 2020, a total of 6,551 adults from Germany was assessed. 4,175 individuals participated in one, 1,070 in two, 803 in three, and 503 in all four waves of data collection. Multilevel analyses revealed that across all assessment waves, COVID-19-related fear, anxiety, and depressive symptoms were significantly higher in individuals with vs. without anxiety, depressive, and other mental disorders. All symptoms decreased on average over time, and this decrease was significantly stronger in individuals with vs. without anxiety disorders, and particularly driven by individuals with generalized anxiety disorder. Our findings suggest that individuals with mental disorders, especially anxiety disorders - and in particular those with a generalized anxiety disorder - seem to be vulnerable to experience psychological strain in the context of the pandemic, might likely overestimate potential threat, and should be targeted by preventive and therapeutic interventions.

Abstract
BACKGROUND The COVID-19 pandemic is related to multiple stressors and therefore may be associated with psychological distress. The aim of this study was to longitudinally assess symptoms of (un-)specific anxiety and depression along different stages of the pandemic to generate knowledge about the progress of psychological consequences of the pandemic and to test the role of potential risk and resilience factors that were derived from cross-sectional studies and official recommendations. METHODS The present study uses a longitudinal observational design with four waves of online data collection (from March 27 to June 15, 2020) in a convenience sample of the general population in Germany. A total of N = 2376 participants that completed at least two waves of the survey were included in the analyses. FINDINGS Specific COVID-19-related anxiety and the average daily amount of preoccupation with the pandemic decreased continuously over the four waves. Unspecific worrying and depressive symptoms decreased on average but not on median level. Self-efficacy, normalization, maintaining social contacts, and knowledge, where to get medical support, were associated with fewer symptoms relative to baseline. Suppression, unhealthy habits, and a longer average daily time of thinking about the pandemic were correlated with a relative increase of symptoms. INTERPRETATION Our findings provide insight into the longitudinal changes of symptoms of psychological distress along the first three months of the COVID-19 pandemic in Germany. Furthermore, we were able to reaffirm the anticipated protective and risk factors that were extracted from previous studies and recommendations.

Associations between COVID-19 related media consumption and symptoms of anxiety, depression and COVID-19 related fear in the general population in Germany.

Abstract
In context of the current COVID-19 pandemic the consumption of pandemic-related media coverage may be an important factor that is associated with anxiety and psychological distress. Aim of the study was to examine those associations in the general population in Germany. 6233 participants took part in an online-survey (March 27th-April 6th, 2020), which included demographic information and media exploitation in terms of duration, frequency and types of media. Symptoms of depression, unspecific anxiety and COVID-19 related anxiety were ascertained with standardized questionnaires. Frequency, duration and diversity of media exposure were positively associated with more symptoms of depression and unspecific and COVID-19 specific anxiety. We obtained the critical threshold of seven times per day and 2.5 h of media exposure to mark the difference between mild and moderate symptoms of (un)specific anxiety and depression. Particularly the usage of social media was associated with more pronounced psychological strain. Participants with pre-existing fears seem to be particularly vulnerable for mental distress related to more immoderate media consumption. Our findings provide some evidence for problematical associations of COVID-19 related media exposure with psychological strain and could serve as an orientation for recommendations-especially with regard to the thresholds of critical media usage.

Abstract
BACKGROUND Aerobic exercise (AE) demonstrated an overall medium treatment effect in anxiety disorders (AD) but there is evidence for an "intensity-response" relationship. High intensity interval training (HIIT) was highly effective on a range of (mental) health parameters. However, so far no randomised-controlled trial (RCT) investigated the efficacy of HIIT in AD. METHODS 33 patients with generalized anxiety disorder (GAD) were randomly assigned to 12-day HIIT or a training of lower intensity (LIT). Anxiety, comorbid depression, stress-related bodily symptoms and perceived control over anxiety related stimuli (PC) were assessed at baseline, post-training and 30 days after baseline by using the Penn State Worry Questionnaire (PSWQ), the Hamilton Inventories for Anxiety and Depression (Ham-A, Ham-D), the Screening for Somatoform Symptoms-7 (SOMS-7) and the Anxiety Control Questionnaire (ACQ-R). RESULTS Both interventions showed moderate or large effects on all clinical measures. However, effects for HIIT were generally about twice as high as for LIT. PC negatively correlated with GAD severity in the whole sample at baseline but an association of training-induced changes in PC and worrying were exclusively detectable in HIIT. CONCLUSION HIIT was highly effective and fast acting in GAD. Therefore, it may complement first-line treatment approaches in this condition.

An investigation of genetic variability of DNA methyltransferases DNMT3A and 3B does not provide evidence for a major role in the pathogenesis of panic disorder and dimensional anxiety phenotypes. J Neural Transm (Vienna) 2020; 127:1527-1537.

Abstract
While DNA methylation patterns have been studied for a role in the pathogenesis of anxiety disorders, the role of the enzymes establishing DNA methylation-DNA methyltransferases (DNMTs)-has yet to be investigated. In an effort to investigate DNMT genotype-specific effects on dimensional anxiety traits in addition to the categorical phenotype of panic disorder, 506 panic disorder patients and 3112 healthy participants were assessed for anxiety related cognition [Agoraphobic Cognitions Questionnaire (ACQ)], anxiety sensitivity [Anxiety Sensitivity Index (ASI)] as well as pathological worry [Penn State Worry Questionnaire (PSWQ)] and genotyped for five single nucleotide polymorphisms (SNPs) in the DNMT3A (rs11683424, rs1465764, rs1465825) and DNMT3B (rs2424932, rs4911259) genes, which have previously been found associated with clinical and trait-related phenotypes. There was no association with the categorical phenotype panic disorder. However, a significant association was discerned between DNMT3A rs1465764 and PSWQ scores in healthy participants, with the minor allele conveying a protective effect. In addition, a marginally significant association between questionnaire scores (PSWQ, ASI) in healthy participants and DNMT3B rs2424932 was detected, again with the minor allele conveying a protective effect. The present results suggest a possible minor role of DNMT3A and DNMT3B gene variation in conveying resilience towards anxiety disorders. As the observed associations indicated a protective effect of two SNPs particularly with pathological worry, future studies are proposed to explore these variants in generalized anxiety disorder rather than panic disorder.

Abstract
Panic disorder (PD) has been linked to abnormalities in information processing. However, only little evidence has been published for sensory gating in PD. Sensory gating describes the brain's ability to exclude stimuli of low relevance from higher level information processing, thereby sustaining efficient cognitive processing. Deficits in sensory gating have been associated with various psychiatric conditions, most prominently schizophrenia. In this case-control event-related potential study, we tested 32 patients with PD and 39 healthy controls in a double click paradigm. Both groups were compared with regard to pre-attentive (P50), early-attentive (N100), and late-attentive (P200) sensory gating indices. Contrary to a hypothesized deficit, PD patients and healthy controls showed no differences in P50, N100 and P200 values. These results suggest that sensory gating seems to be functional across the pre-attentive, early-attentive, and late-attentive time span in this clinical population. Given this consistency across auditory sensory gating indices, further research aiming to clarify information processing deficits in PD should focus on other neurophysiological markers to investigate information processing deficits in PD (eg, P300, error-related negativity or mismatch negativity).

Risk, resilience, psychological distress, and anxiety at the beginning of the COVID-19 pandemic in Germany. Brain Behav 2020; 10:e01745. [PMID: 32633464 PMCID: PMC7361063 DOI: 10.1002/brb3.1745] [Citation(s) in RCA: 223] [Impact Index Per Article: 55.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 06/09/2020] [Accepted: 06/19/2020] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND The current COVID-19 pandemic comes with multiple psychological stressors due to health-related, social, economic, and individual consequences and may cause psychological distress. The aim of this study was to screen the population in Germany for negative impact on mental health in the current COVID-19 pandemic and to analyze possible risk and protective factors. METHODS A total of 6,509 people took part in an online survey in Germany from 27 March to 6 April. The questionnaire included demographic information and ascertained psychological distress, anxiety and depressive symptoms, and risk and protective factors. RESULTS In our sample, over 50% expressed suffering from anxiety and psychological distress regarding the COVID-19 pandemic. Participants spent several hours per day thinking about COVID-19 (M = 4.45). Psychological and social determinants showed stronger associations with anxiety regarding COVID-19 than experiences with the disease. CONCLUSIONS The current COVID-19 pandemic does cause psychological distress, anxiety, and depression for large proportions of the general population. Strategies such as maintaining a healthy lifestyle and social contacts, acceptance of anxiety and negative emotions, fostering self-efficacy, and information on where to get medical treatment if needed, seem of help, while substance abuse and suppression of anxiety and negative emotions seem to be associated with more psychological burden.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic may cause psychological distress in the general population and has the potential to cause anxiety regarding COVID-19. No validated questionnaires exist for the measurement of specific COVID-19 anxiety. We modified the DSM 5 - Severity Measure for Specific Phobia-Adult scale specifically for anxiety regarding COVID-19, and report the psychometric properties from an online study with 6262 participants from the general population in Germany. We analysed internal consistency as well as concordant validity. The scale showed good internal consistency (α = 0.86) and good concordant validity (rs = 0.60) with the 2-item Generalized Anxiety Disorder measure and rs = 0.61 with self-rating of limitations in daily life caused by COVID-19 anxiety.

Changes in Dosing and Dose Timing of D-Cycloserine Explain Its Apparent Declining Efficacy for Augmenting Exposure Therapy for Anxiety-related Disorders: An Individual Participant-data Meta-analysis. J Anxiety Disord 2019; 68:102149. [PMID: 31698111 PMCID: PMC9119697 DOI: 10.1016/j.janxdis.2019.102149] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Revised: 09/19/2019] [Accepted: 09/22/2019] [Indexed: 12/25/2022]
Abstract
The apparent efficacy of d-cycloserine (DCS) for enhancing exposure treatment for anxiety disorders appears to have declined over the past 14 years. We examined whether variations in how DCS has been administered can account for this "declining effect". We also investigated the association between DCS administration characteristics and treatment outcome to find optimal dosing parameters. We conducted a secondary analysis of individual participant data obtained from 1047 participants in 21 studies testing the efficacy of DCS-augmented exposure treatments. Different outcome measures in different studies were harmonized to a 0-100 scale. Intent-to-treat analyses showed that, in participants randomized to DCS augmentation (n = 523), fewer DCS doses, later timing of DCS dose, and lower baseline severity appear to account for this decline effect. More DCS doses were related to better outcomes, but this advantage leveled-off at nine doses. Administering DCS more than 60 minutes before exposures was also related to better outcomes. These predictors were not significant in the placebo arm (n = 521). Results suggested that optimal DCS administration could increase pre-to-follow-up DCS effect size by 50%. In conclusion, the apparent declining effectiveness of DCS over time may be accounted for by how it has been administered. Optimal DCS administration may substantially improve outcomes.

Abstract
Music performance anxiety (MPA) is one of the most common disorders among professional musicians, nevertheless, little is known about the disease. With this systematic review, prevalence, risk factors and treatment procedures for MPA were assessed, and for the first time, quality assessments were carried out for all studies using standardized assessment tools. A systematic literature search was conducted via search algorithms in the databases MEDLINE, EMBASE, CINAHL, PsycArticles, PsycInfo and ERIC. Included were case reports, case-control, cohort, cross-sectional and intervention studies examining professional musicians with MPA. For quality assessment, adapted tools of the National Heart, Lung, and Blood Institute were used. A total of 43 studies were included (10 case reports, 21 intervention, 11 cross-sectional, one cohort study). Quality ratings ranged from -11 to 6 out of a maximum of 15/16 points for cross-sectional/cohort studies and -4 to 11 out of 18 points for intervention studies. The prevalence of MPA was between 16.5% and 60%. More women than men were affected and musicians older than 45-50 years reported less MPA than younger musicians. Regarding treatment cognitive behavioural therapy (CBT) and β-blockers were most often researched with beneficial results for CBT. However, studies with adequate control groups for CBT interventions are needed to clarify its efficacy. Studies showed methodological weaknesses, especially in the selection of participants, recording of influencing factors, blinding of interventions, randomization of participants and analysis of comorbidity. Recommendations for further research are made.

Reduced Sensitivity to Non-Fear-Related Stimulus Changes in Panic Disorder. Neuropsychobiology 2019; 78:31-37.

Abstract
Panic disorder (PD) is associated with increased body vigilance and reduced cognitive resources directed at non-fear-related stimuli, particularly in the absence of stimulus-rich environments. To date, only few studies have investigated whether this deficit in PD is reflected in reduced mismatch negativity (MMN), an event-related potential indexing preattentive sensitivity to unexpected stimulus changes. We tested 35 patients affected by PD and 42 matched healthy controls in an oddball paradigm, using frequency and duration deviant stimuli to measure auditory MMN. PD patients displayed reduced duration MMN amplitudes in comparison to healthy controls. No group differences were detected for duration MMN latency, as well as frequency MMN indices. Results support the notion of reduced processing of non-fear-related stimuli in PD patients, particularly with regard to the preattentive processing of sound duration deviants. Additionally, our findings are in line with clinical studies reporting divergent deficits in preattentive processing of frequency and duration deviants.

Abstract
Patients with anxiety disorders have a lower heart rate variability (HRV) than healthy controls. Low HRV is associated with cardiovascular disease and dysfunction of the autonomic nervous system (ANS). The aim of the present study was to investigate if HRV in patients with agoraphobia with or without panic disorder can be influenced by cognitive behavioral therapy (CBT). 73 patients with agoraphobia with or without panic disorder were included in the study. Heart rate (HR) and HRV were recorded at rest before and after CBT and during in-vivo exposure. No changes in HR and HRV were observed throughout therapy. During in-vivo exposure HRV increased significantly and HR exhibited a tendency to decrease. Despite clinical improvement of anxiety symptoms, ANS activity at rest did not seem to be influenced by CBT. However, during in-vivo exposure, HRV changed significantly, indicating a higher parasympathetic activity at the end of exposure.

Abstract
The use of d-cycloserine (DCS) to augment exposure based therapy for anxiety disorders has shown mixed, although overall positive effects. Aim of the present study was to examine post-exposure administration of DCS in patients with agoraphobia with or without panic disorder. 73 patients with agoraphobia (with or without panic disorder) were treated with 12 sessions of cognitive behavioral therapy (CBT) including 3 exposures. Following successful exposure patients were given double blind either placebo or 50 mg of DCS. Primary outcome criterion was change in the Panic and Agoraphobia Scale (PAS) between CBT session t1, t4 (+∼2 months), t10 (+∼3 months) und t11 (+∼4 months). During the course of CBT the patients' symptomatology decreased significantly as measured by primary and secondary outcome criteria, however, without an additional benefit for DCS treated patients. Exploratory sub-group analyses for severely ill patients and patients with high anxiety and strong habituation during exposure showed that DCS administration was associated with increased improvement during the 1-month follow-up period (t10 - t11) with medium to large effect sizes (range in effect size η2p from .06 to .25). Our study results are consistent with recent research on DCS, indicating a beneficial augmentative effect for sub-groups of anxiety patients. The lack of an overall DCS effect for the whole patient sample might be explained by a dual mechanism in fear conditioning and extinction with different cognitive processes being involved during exposure depending on the degree of anxiety experienced by the patient.

Abstract
BACKGROUND Patients' characteristics and antidepressants are discussed to be relevant in the context of phobic exposure. AIMS To identify patients characteristics associated with a differential course of fear during disorder-specific symptom provocation as well as to elucidate the effect of selective serotonin-(noradrenalin-) reuptake inhibitors [SS(N)RI] on development of fear in the context of re-exposure to the phobic stimuli. METHODS Twenty-eight clinically well-characterized patients with panic disorder and agoraphobia (PD/AG) were classified into subjects who show a reduction of fear ('Fear-') during a symptom provocation via a picture-based paradigm (T1) and those who did not ('Fear+'). Subsequently, SS(N)RI treatment was administered to all patients and subjects were re-exposed to the feared stimuli after 8 weeks of treatment (T2). Moreover, brain activity within the 'fear network' was measured via functional magnetic resonance imaging (fMRI) at T1 and T2. RESULTS Fear - were significantly younger and demonstrated increased exposure-related fear as well as stronger activity in several fear-related brain areas than Fear+. We found significant improvements in all clinical parameters after pharmacological intervention for the whole sample (T1-T2; all measures p < .02). However, reduction of fear as well as activation in (para)limbic structures during symptom provocation were now attenuated in Fear - but increased in Fear+. CONCLUSIONS Advanced age may predict a therapeutically unfavorable course of fear during agoraphobic symptom provocation. Since we found no negative impact of medication on fear development at all, there was some evidence that SS(N)RI treatment might improve the individual ability to get involved with the agoraphobic stimuli while conducting disorder-specific exposure.

Abstract
Exposure-based Cognitive Behavioral Therapy (eb-CBT) represents the most evidence-based psychotherapeutic approach in anxiety disorders. However, its efficacy may be limited by a delay in onset of action and a substantial number of patients does not respond sufficiently to treatment. In this context, aerobic exercise was found to be effective in reducing clinical anxiety as well as to improve (elements of) disorder-specific CBT in some mental disorders. We therefore investigated the effect of aerobic exercise supplementary to an eb-CBT in panic disorder and agoraphobia (PD/AG). 77 patients with PD/AG performed a 30 min treadmill task with moderate or low intensity (70% or 30% of the maximal oxygen uptake [VO2max]) prior to five exposure sessions within a standardized seven-week CBT. At baseline, after completing the treatment period (post) and six month after post (follow-up), several measures of (un)specific psychopathology (Hamilton Anxiety Rating Scale [Ham-A], Mobility Inventory [MI], Panic and Agoraphobia Scale [PAS], Agoraphobic Cognitions Questionnaire [ACQ], Body Sensations Questionnaire [BSQ]) were established to assess for clinical changes. All patients experienced a significant improvement of symptoms from baseline to post (for all measures p < .001) but repeated-measures analyses of variance found a trend towards a significant time × group interaction in the Ham-A in favor for the moderate intense exercise group (f[1, 74] = 4.15, p = .045, α=.025). This trend, however, disappeared at follow-up since the low-intense exercise group further improved significantly in Ham-A after post. Our findings therefore might point to an accelerating effect of moderate-intense exercise within an exposure-based CBT for AG/PD.

Abstract
BACKGROUND Physical activity has shown to be effective in anxiety disorders. For specific phobia, no studies are available that systematically examined the effects of an aerobic exercise intervention on phobic fear within a randomized-controlled design. Therefore, we investigated the acute effect of a standardized aerobic training on clinical symptoms of dental phobia as well as on stress-related neurobiological markers. METHODS Within a crossover design, 30 patients with dental phobia (mean age: 34.1 years; mean score of the Dental Anxiety Scale: 18.8) underwent two minor dental interventions separated by 7 days. Dental treatment was performed after 30 min of physical activity at either 20% VO2 max (control) or 70% VO2 max (intervention), respectively. To control for habituation, patients were randomly assigned to one of the two conditions prior to the first intervention. Moreover, saliva samples were collected at five times in order to determine changes in salivary cortisol (sC) and alpha-amylase (sAA) due to treatment. RESULTS In comparison to baseline, aerobic exercise within 70% VO2 max significantly reduced clinical anxiety and sC concentrations before, during, and after the dental treatment. In contrast, the control condition led to decreased sAA levels at different time points of measurement. Habituation occurred at the second study day, independent of the order. CONCLUSIONS Our study provides evidence for an effect of moderate-intense exercise on clinical symptoms and sC in patients with dental phobia. Therefore, acute aerobic exercise might be a simple and low-cost intervention to reduce disorder-specific phobic fear.

Abstract
INTRODUCTION Physical activity (PA) can play an important role in improving the mental and physical health in patients with mental disorders but is not well studied in this population. The aim of this study was to assess the status of PA in outpatients with mental disorders, compare the convergence of self-rating and accelerometer measurement and examine the influence of social cognitive variables from the Motivation-Volition (MoVo) model and clinical measures on PA. METHODS Eighty-four patients were recruited from three psychiatric outpatient clinics and local psychiatrists (Distribution of ICD-10-Diagnoses: F3.x = 59.5%, F4.x = 20.2%, F2.x = 17.9%, F1.x = 2.4%). PA, Self-efficacy, Outcome-expectancies, Intention, Self-concordance, Action- and Coping-planning, Health-related Quality of Life (SF-12) and Psychiatric Symptoms (SCL-27) were assessed through questionnaires. PA was assessed objectively by accelerometers. RESULTS Most of the participants did not reach PA recommendations. Subjective and objective measurement of PA showed good accordance for total PA on group level but lower accordance on individual level. Motivational and volitional determinants of health behavior change showed a similar pattern of correlations with PA as in populations without mental disorders. CONCLUSION Outpatients with mental disorders have the ability and are willing to perform PA but a large proportion of our sample did not meet PA recommendations. To assess group levels of PA, subjective and objective measurement seem equally apt, for individual diagnostics, a combination of both should be considered. Social cognitive determinants of health behavior change seem to be as helpful for the design of PA interventions for patients with mental disorders as they are in other populations.

Abstract
IMPORTANCE Whether and under which conditions D-cycloserine (DCS) augments the effects of exposure-based cognitive behavior therapy for anxiety, obsessive-compulsive, and posttraumatic stress disorders is unclear. OBJECTIVE To clarify whether DCS is superior to placebo in augmenting the effects of cognitive behavior therapy for anxiety, obsessive-compulsive, and posttraumatic stress disorders and to evaluate whether antidepressants interact with DCS and the effect of potential moderating variables. DATA SOURCES PubMed, EMBASE, and PsycINFO were searched from inception to February 10, 2016. Reference lists of previous reviews and meta-analyses and reports of randomized clinical trials were also checked. STUDY SELECTION Studies were eligible for inclusion if they were (1) double-blind randomized clinical trials of DCS as an augmentation strategy for exposure-based cognitive behavior therapy and (2) conducted in humans diagnosed as having specific phobia, social anxiety disorder, panic disorder with or without agoraphobia, obsessive-compulsive disorder, or posttraumatic stress disorder. DATA EXTRACTION AND SYNTHESIS Raw data were obtained from the authors and quality controlled. Data were ranked to ensure a consistent metric across studies (score range, 0-100). We used a 3-level multilevel model nesting repeated measures of outcomes within participants, who were nested within studies. RESULTS Individual participant data were obtained for 21 of 22 eligible trials, representing 1047 of 1073 eligible participants. When controlling for antidepressant use, participants receiving DCS showed greater improvement from pretreatment to posttreatment (mean difference, -3.62; 95% CI, -0.81 to -6.43; P = .01; d = -0.25) but not from pretreatment to midtreatment (mean difference, -1.66; 95% CI, -4.92 to 1.60; P = .32; d = -0.14) or from pretreatment to follow-up (mean difference, -2.98, 95% CI, -5.99 to 0.03; P = .05; d = -0.19). Additional analyses showed that participants assigned to DCS were associated with lower symptom severity than those assigned to placebo at posttreatment and at follow-up. Antidepressants did not moderate the effects of DCS. None of the prespecified patient-level or study-level moderators was associated with outcomes. CONCLUSIONS AND RELEVANCE D-cycloserine is associated with a small augmentation effect on exposure-based therapy. This effect is not moderated by the concurrent use of antidepressants. Further research is needed to identify patient and/or therapy characteristics associated with DCS response.

Abstract
INTRODUCTION Cognitive behavioural therapy (CBT) and pharmacological treatment with selective serotonin or serotonin-noradrenalin reuptake inhibitors (SSRI/SSNRI) are regarded as efficacious treatments for panic disorder with agoraphobia (PD/AG). However, little is known about treatment-specific effects on symptoms and neurofunctional correlates. EXPERIMENTAL PROCEDURES We used a comparative design with PD/AG patients receiving either two types of CBT (therapist-guided (n=29) or non-guided exposure (n=22)) or pharmacological treatment (SSRI/SSNRI; n=28) as well as a wait-list control group (WL; n=15) to investigate differential treatment effects in general aspects of fear and depression (Hamilton Anxiety Rating Scale HAM-A and Beck Depression Inventory BDI), disorder-specific symptoms (Mobility Inventory MI, Panic and Agoraphobia Scale subscale panic attacks PAS-panic, Anxiety Sensitivity Index ASI, rating of agoraphobic stimuli) and neurofunctional substrates during symptom provocation (Westphal-Paradigm) using functional magnetic resonance imaging (fMRI). Comparisons of neural activation patterns also included healthy controls (n=29). RESULTS Both treatments led to a significantly greater reduction in panic attacks, depression and general anxiety than the WL group. The CBT groups, in particular, the therapist-guided arm, had a significantly greater decrease in avoidance, fear of phobic situations and anxiety symptoms and reduction in bilateral amygdala activation while the processing of agoraphobia-related pictures compared to the SSRI/SSNRI and WL groups. DISCUSSION This study demonstrates that therapist-guided CBT leads to a more pronounced short-term impact on agoraphobic psychopathology and supports the assumption of the amygdala as a central structure in a complex fear processing system as well as the amygdala's involvement in the fear system's sensitivity to treatment.

Aerobic exercise training facilitates the effectiveness of cognitive behavioral therapy in panic disorder. Depress Anxiety 2015; 32:221-8. [PMID: 25515221 DOI: 10.1002/da.22337] [Citation(s) in RCA: 45] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2014] [Revised: 10/22/2014] [Accepted: 11/02/2014] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Physical activity has been discussed as a therapeutic alternative or add-on for the treatment of anxiety disorders. We studied whether aerobic exercise compared to physical activity with low impact can improve the effect of cognitive behavioral therapy (CBT) in patients with panic disorder (PD) with/without agoraphobia. METHODS Forty-seven patients received group CBT treatment over 1 month, which was augmented with an 8-week protocol of either aerobic exercise (three times/week, 30 min, 70% VO(2) max; n = 24) or a training program including exercises with very low intensity (n = 23) in a randomized controlled double-blind design. The primary outcome measure was the total score on the Hamilton Anxiety Scale (Ham-A). A 2 × 3 analysis of covariance (ANCOVA) with baseline value as a covariate was conducted for data analysis. RESULTS Time × group interaction for the Ham-A revealed a significant effect (P = .047, η(2) p = .072), which represented the significant group difference at a 7-month follow-up. For the other clinical outcome measures no statistical significance emerged, although improvement was more sustained in the exercise group. CONCLUSIONS For patients with PD, regular aerobic exercise adds an additional benefit to CBT. This supports previous results and provides evidence about the intensity of exercise that needs to be performed.

Who is stressed? A pilot study of salivary cortisol and alpha-amylase concentrations in agoraphobic patients and their novice therapists undergoing in vivo exposure. Psychoneuroendocrinology 2014; 49:280-9. [PMID: 25127086 DOI: 10.1016/j.psyneuen.2014.07.016] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2014] [Revised: 06/26/2014] [Accepted: 07/15/2014] [Indexed: 10/25/2022]
Abstract
In cognitive behavioural therapy of phobic anxiety, in vivo exposure is considered as an effective treatment strategy. Apparently, it involves the experience of stress and anxiety in patients. Given the therapist's role during exposure sessions, it is conceivable that the performance is also accompanied with the experience of stress in therapists, especially when unversed in conducting psychotherapy. Studies confirmed that cognitive behavioural therapists tend to avoid therapist-guided in vivo exposure. The objective of this study was the simultaneous investigation of therapist's and patient's stress response during in vivo exposure. Therefore, 23 agoraphobic patients and their 23 treating therapists in training provided five saliva samples during an in vivo exposure and five samples during an ordinary therapy session. Before and during exposure session, subjective evaluations of stress and anxiety were assessed. Results suggested that therapists reported similar levels of perceived stress as patients before exposure. Both groups displayed significantly elevated salivary cortisol (sC) levels during exposure compared to the control session and a trend for alterations in salivary alpha-amylase (sAA) activity was found. Therapists reached peak concentrations of sC before start of the intervention followed by a decline during exposure, while patients displayed peak levels of cortisol secretion after 60 min of exposure. In vivo exposure seems to be a demanding intervention not only for the patient, but also for therapists in training. However, it was also demonstrated that physiological and subjective stress rather decrease during the intervention and that both groups rated exposure to be substantially successful. Based on the presented results, another potential factor contributing to the under-usage of exposure treatment is conceivable and needs to be addressed in future research.

Effect of combined cognitive-behavioural therapy and endurance training on cortisol and salivary alpha-amylase in panic disorder. J Psychiatr Res 2014; 58:12-9.

Abstract
Current data point to an alteration of both the hypothalamo-pituitary-adrenal (HPA)-system and the peripheral transmission of catecholamines in anxiety disorders. There is also some evidence for the effect of several components of cognitive-behavioural interventions such as coping and control and for an effect of exercise training on the neuroendocrine stress response in healthy subjects as well as patients suffering from distinct (mental) disorders. This double-blind, controlled study investigated the effect of cognitive-behavioural therapy (CBT) in combination with either high-level endurance training or low-level exercise on salivary cortisol (sC) and on levels of salivary alpha-amylase (sAA) in patients suffering from panic disorder (PD) with and without agoraphobia. In comparison to the low-level exercise condition, there were significantly lower sC-levels in the experimental group performing high-level endurance training at a 7-month follow-up. In contrast, there were no group differences in sAA levels during the study period. In this trial, we found evidence for a decelerated effect of endurance-training on HPA-system's functioning in PD. Further studies addressing the alteration of sAA levels in this population might investigate physical exercise different in intensity and duration.

Abstract
Generalized anxiety disorder (GAD) is a prevalent mental condition with substantial impact on psychosocial functioning and quality of life. There is also an increased risk of comorbidity with several other mental and somatic diseases. Clinical symptomatology is characterized by excessive and uncontrollable worrying about distinct issues of daily living which is frequently associated with somatic symptoms of stress and anxiety. Neurobiological and psychological research provide evidence for alterations in (para) limbic areas, a disturbed monoaminergic transmission as well as for dysfunctional learning in the pathogenesis of GAD. Therefore, second generation antidepressants, such as selective serotonin reuptake inhibitors (SSRI), selective serotonin-norepinephrine reuptake inhibitors (SSNRI), the calcium channel modulator pregabalin and cognitive behavioral therapy (CBT) are the first choice treatment options. Depending on symptom severity, patient preference and availability, both medication and CBT can be applied as monotherapy or in combination.

D-cycloserine does not improve but might slightly speed up the outcome of in-vivo exposure therapy in patients with severe agoraphobia and panic disorder in a randomized double blind clinical trial. J Psychiatr Res 2011; 45:1042-7.

Abstract
D-cycloserine (DCS)-augmented exposure therapy has proven efficacy in the treatment of acrophobia, social phobia, panic disorder and OCD. Here we studied whether DCS can also improve the effect of cognitive behavioral therapy (CBT) in patients with agoraphobia and panic disorder. To this end, 39 patients with the diagnoses of agoraphobia and panic disorder were treated with 11 sessions of CBT including three individual in-vivo exposure sessions (flooding), augmented with either 50mg of DCS (N=20) or placebo (N=19) in a randomized double blind design. Primary outcome was the total score of the panic and agoraphobia scale. Both groups profited considerably from therapy and DCS did not significantly improve this outcome (p=0.475; η(2)p = 0.01). However, there was a statistical trend (p=0.075; η(2)p = 0.17) in the more severely ill patients that DCS accelerated symptom reduction in the primary outcome at post-therapy. No serious adverse effects occurred during the trial. We conclude that in patients with agoraphobia and panic disorder, DCS seems to lack an additional benefit to efficient cbt, probably due to a floor effect. Nonetheless, the acceleration of symptom reduction in severely ill patients might represent a valuable treatment option deserving further investigation.

Abstract
Background Restless legs syndrome (RLS) is a sleep related movement disorder that occurs both in an idiopathic form and in symptomatic varieties. RLS is a frequent and distressing comorbidity in end stage renal disease (ESRD). For idiopathic RLS (iRLS), genetic risk factors have been identified, but their role in RLS in ESRD has not been investigated yet. Therefore, a case–control association study of these variants in ESRD patients was performed. Methods The study genotyped 10 iRLS associated variants at four loci encompassing the genes MEIS1, BTBD9, MAP2K5/SKOR1, and PTPRD, in two independent case–control samples from Germany and Greece using multiplex PCR and MALDI-TOF (matrix assisted laser desorption/ionisation time-of-flight) mass spectrometry. Statistical analysis was performed as logistic regression with age and gender as covariates. For the combined analysis a Cochran–Mantel–Haenszel test was applied. Results The study included 200 RLS-positive and 443 RLS-negative ESRD patients in the German sample, and 141 and 393 patients, respectively, in the Greek sample. In the German sample, variants in MEIS1 and BTBD9 were associated with RLS in ESRD (Pnom≤0.004, ORs 1.52 and 1.55), whereas, in the Greek sample, there was a trend for association to MAP2K5/SKOR1 and BTBD9 (Pnom≤0.08, ORs 1.41 and 1.33). In the combined analysis including all samples, BTBD9 was associated after correction for multiple testing (Pcorrected=0.0013, OR 1.47). Conclusions This is the first demonstration of a genetic influence on RLS in ESRD patients with BTBD9 being significantly associated. The extent of the genetic predisposition could vary between different subgroups of RLS in ESRD.
