In der Literatur wird eine hohe Komorbidität zwischen Anorexia nervosa und Angststörungen beschrieben. Die Dissertation beinhaltet eine klinische Studie anhand von 29 anorektischen Patientinnen, in der der Zusammenhang zwischen der Ausprägung der Angst und dem Schweregrad der Anorexia nervosa untersucht wurde. Als Testverfahren kamen zur Anwendung State-Trait-Angstinventar (Stai), Sozialphobie und -angstinventar für Kinder (SPAIK), Anorexia nervosa Inventar zur Selbstbeobachtung (ANIS), Fragebogen zum Eßverhalten (FEV), Eating Disorder Inventory (EDI) und Body Mass Index (BMI). Es zeigte sich eine deutliche Korrelation zwischen der Angst und der Ausprägung der psychopathologischen Symptomatik der Eßstörung. Ein vermuteter Zusammenhang zwischen niedrigem Ausgangs - BMI und hohem Angstniveau konnte nicht bestätigt werden.
Background
Although 5-HTTLPR has been shown to influence the risk of life stress-induced depression in the majority of studies, others have produced contradictory results, possibly due to weak effects and/or sample heterogeneity.
Methods
In the present study we investigated how age, type and intensity of life-stressors modulate the effect of 5-HTTLPR on depression and anxiety in a European population cohort of over 2300 subjects. Recent negative life events (RLE), childhood adversity (CHA), lifetime depression, Brief Symptoms Inventory (BSI) depression and anxiety scores were determined in each subject. Besides traditional statistical analysis we calculated Bayesian effect strength and relevance of 5-HTTLPR genotypes in specified models.
Results
The short (s) low expressing allele showed association with increased risk of depression related phenotypes, but all nominally significant effects would turn to non-significant after correction for multiple testing in the traditional analysis. Bayesian effect strength and relevance analysis, however, confirmed the role of 5-HTTLPR. Regarding current (BSI) and lifetime depression 5-HTTLPR-by-RLE interactions were confirmed. Main effect, with other words direct association, was supported with BSI anxiety. With more frequent RLE the prevalence or symptoms of depression increased in ss carriers. Although CHA failed to show an interaction with 5-HTTLPR, in young subjects CHA sensitized towards the depression promoting effect of even mild RLE. Furthermore, the direct association of anxiety with the s allele was driven by young (\(\leq\)30) individuals.
Limitations
Our study is cross-sectional and applies self-report questionnaires.
Conclusions
Albeit 5-HTTLPR has only weak/moderate effects, the s allele is directly associated with anxiety and modulates development of depression in homogeneous subgroups.
This study examined (1) the availability and content of national CPGs for treatment of peripartum depression, including comorbid anxiety, with antidepressants and other psychotropics across Europe and (2) antidepressant and other psychotropic utilization data as an indicator of prescribers' compliance to the guidelines. We conducted a search using Medline and the Guidelines International Network database, combined with direct e-mail contact with national Riseup-PPD COST ACTION members and researchers within psychiatry. Of the 48 European countries examined, we screened 41 records and included 14 of them for full-text evaluation. After exclusion of ineligible and duplicate records, we included 12 CPGs. Multiple CPGs recommend antidepressant initiation or continuation based on maternal disease severity, non-response to first-line non-pharmacological interventions, and after risk-benefit assessment. Advice on treatment of comorbid anxiety is largely missing or unspecific. Antidepressant dispensing data suggest general prescribers' compliance with the preferred substances of the CPG, although country-specific differences were noted. To conclude, there is an urgent need for harmonized, up-to-date CPGs for pharmacological management of peripartum depression and comorbid anxiety in Europe. The recommendations need to be informed by the latest available evidence so that healthcare providers and women can make informed, evidence-based decisions about treatment choices.
Animal models are used to study neurobiological mechanisms in mental disorders. Although there has been significant progress in the understanding of neurobiological underpinnings of threat-related behaviors and anxiety, little progress was made with regard to new or improved treatments for mental disorders. A possible reason for this lack of success is the unknown predictive and cross-species translational validity of animal models used in preclinical studies. Re-translational approaches, therefore, seek to establish cross-species translational validity by identifying behavioral operations shared across species. To this end, we implemented a human open field test in virtual reality and measured behavioral indices derived from animal studies in three experiments (N=31, N=30, and N=80). In addition, we investigated the associations between anxious traits and such behaviors. Results indicated a strong similarity in behavior across species, i.e., participants in our study-like rodents in animal studies-preferred to stay in the outer region of the open field, as indexed by multiple behavioral parameters. However, correlational analyses did not clearly indicate that these behaviors were a function of anxious traits of participants. We conclude that the realized virtual open field test is able to elicit thigmotaxis and thus demonstrates cross-species validity of this aspect of the test. Modulatory effects of anxiety on human open field behavior should be examined further by incorporating possible threats in the virtual scenario and/or by examining participants with higher anxiety levels or anxiety disorder patients.
Virtual reality (VR) has made its way into mainstream psychological research in the last two decades. This technology, with its unique ability to simulate complex, real situations and contexts, offers researchers unprecedented opportunities to investigate human behavior in well controlled designs in the laboratory. One important application of VR is the investigation of pathological processes in mental disorders, especially anxiety disorders. Research on the processes underlying threat perception, fear, and exposure therapy has shed light on more general aspects of the relation between perception and emotion. Being by its nature virtual, i.e., simulation of reality, VR strongly relies on the adequate selection of specific perceptual cues to activate emotions. Emotional experiences in turn are related to presence, another important concept in VR, which describes the user's sense of being in a VR environment. This paper summarizes current research into perception of fear cues, emotion, and presence, aiming at the identification of the most relevant aspects of emotional experience in VR and their mutual relations. A special focus lies on a series of recent experiments designed to test the relative contribution of perception and conceptual information on fear in VR. This strand of research capitalizes on the dissociation between perception (bottom up input) and conceptual information (top-down input) that is possible in VR. Further, we review the factors that have so far been recognized to influence presence, with emotions (e.g., fear) being the most relevant in the context of clinical psychology. Recent research has highlighted the mutual influence of presence and fear in VR, but has also traced the limits of our current understanding of this relationship. In this paper, the crucial role of perception on eliciting emotional reactions is highlighted, and the role of arousal as a basic dimension of emotional experience is discussed. An interoceptive attribution model of presence is suggested as a first step toward an integrative framework for emotion research in VR. Gaps in the current literature and future directions are outlined.
The effect of inherently threatening contexts on visuocortical engagement to conditioned threat
(2023)
Fear and anxiety are crucial for adaptive responding in life‐threatening situations. Whereas fear is a phasic response to an acute threat accompanied by selective attention, anxiety is characterized by a sustained feeling of apprehension and hypervigilance during situations of potential threat. In the current literature, fear and anxiety are usually considered mutually exclusive, with partially separated neural underpinnings. However, there is accumulating evidence that challenges this distinction between fear and anxiety, and simultaneous activation of fear and anxiety networks has been reported. Therefore, the current study experimentally tested potential interactions between fear and anxiety. Fifty‐two healthy participants completed a differential fear conditioning paradigm followed by a test phase in which the conditioned stimuli were presented in front of threatening or neutral contextual images. To capture defense system activation, we recorded subjective (threat, US‐expectancy), physiological (skin conductance, heart rate) and visuocortical (steady‐state visual evoked potentials) responses to the conditioned stimuli as a function of contextual threat. Results demonstrated successful fear conditioning in all measures. In addition, threat and US‐expectancy ratings, cardiac deceleration, and visuocortical activity were enhanced for fear cues presented in threatening compared with neutral contexts. These results are in line with an additive or interactive rather than an exclusive model of fear and anxiety, indicating facilitated defensive behavior to imminent danger in situations of potential threat.
SLC6A2-regulierende microRNAs bei Angsterkrankungen: Genexpressions- und Assoziationsuntersuchungen
(2021)
Angsterkrankungen sind häufige Krankheitsbilder mit bislang nicht vollständig geklärter multifaktorieller Ätiologie. Neben Umwelt- und psychosozialen Faktoren zeigen Studien eine signifikante familiäre Häufung und lassen eine genetische Komponente mit einer Heritabilität in einem Bereich von 30-60 % vermuten. Da hierbei am ehesten von einem komplexen Zusammenspiel verschiedenster Gene mit unterschiedlicher Relevanz auszugehen ist, stellen miRNAs eine bedeutende Größe dar, da sie es vermögen auf transkriptioneller Ebene Einfluss auf die Regulierung einer Vielzahl von Genen zu nehmen.
Verschiedene Aspekte liefern Hinweise darauf, dass eine Neurotransmitterdysregulation eine wichtige Komponente in der Pathogenese von Angsterkrankungen einnimmt – insbesondere veränderte noradrenerge Signalwege sind hierbei entscheidend beteiligt. Dies macht den Noradrenalin-Transporter bzw. SLC6A2 zu einem interessanten Kandidatengen, und stellt die Bezugsgröße der angestellten Untersuchungen in dieser Arbeit dar. miRNAs, welche die SLC6A2-Expression modulieren, können somit Einfluss auf zentrale Verarbeitungswege von Angst nehmen.
Im ersten Teil der vorliegenden Arbeit wurden potentielle miRNA-Regulatoren von SLC6A2 in silico ermittelt und in einem weiteren Schritt in vitro überprüft. Zehn der miRNAs (hsa-miR-378g, hsa-miR-330-5p, hsa-miR-4781-5p, hsa-miR664b-3p, hsa-miR-4715-3p, hsa-miR-579-3p, hsa-miR-3921, hsa-miR-3622b-5p, hsa-miR-4773, hsa-miR-532-3p) zeigten hierbei eine relevante Abnahme der Luciferase-Aktivität als Hinweis auf ihre funktionelle Relevanz und stellen damit die Basis der nachfolgenden Untersuchungen dar.
Im zweiten Teil der Arbeit wurden Einzelbasenpolymorphismen im Bereich der zuvor ermittelten miRNA-Gene sowie eines SNP innerhalb der 3’-UTR von SLC6A2 mittels Fall-Kontroll-Studie in einer Population von Patienten mit Panikstörung und entsprechenden Kontrollen untersucht. Eine nominelle Assoziation ließ sich für das (minor) T-Allel von rs2910931 (stromaufwärts von MIR579) (p-allel = 0,004) sowie das (major) A-Allel von rs2582372 (p-allel = 0,023) feststellen. In Einklang hiermit ließ sich weiterhin für rs2910931 eine signifikante Assoziation zwischen der Anzahl der (minor) T-Allele und dem ASI-Wert (β = 0,371, p = 0,029, 95 %-CI 0,039-0,702) sowie dem ACQ-Wert (β = 0,012, p = 0,041, 95 %-CI 0,000-0,023) ermitteln. Somit zeigt sich eine Einflussnahme der genetischen Variante um MIR579 auf die Feinmodulation der Noradrenalin-Homöostase als möglichem ätiopathogenetischen Faktor von Angsterkrankungen.
Pharmacobehavioral studies in experimental animals, and imaging studies in humans, indicate that serotonergic transmission in the amygdala plays a key role in emotional processing, especially for anxiety-related stimuli. The lateral and basolateral amygdaloid nuclei receive a dense serotonergic innervation in all species studied to date. We investigated interrelations between serotonergic afferents and neuropeptide Y (NPY)-producing neurons, which are a subpopulation of inhibitory interneurons in the rat lateral and basolateral nuclei with particularly strong anxiolytic properties. Dual light microscopic immunolabeling showed numerous appositions of serotonergic afferents on NPY-immunoreactive somata. Using electron microscopy, direct membrane appositions and synaptic contacts between serotonin-containing axon terminals and NPY-immunoreactive cellular profiles were unequivocally established. Double in situ hybridization documented that more than 50 %, and about 30–40 % of NPY mRNA-producing neurons, co-expressed inhibitory 5-HT1A and excitatory 5-HT2C mRNA receptor subtype mRNA, respectively, in both nuclei with no gender differences. Triple in situ hybridization showed that individual NPY mRNA-producing interneurons co-express both 5-HT1A and 5-HT2C mRNAs. Co-expression of NPY and 5-HT3 mRNA was not observed. The results demonstrate that serotonergic afferents provide substantial innervation of NPY-producing neurons in the rat lateral and basolateral amygdaloid nuclei. Studies of serotonin receptor subtype co-expression indicate a differential impact of the serotonergic innervation on this small, but important, population of anxiolytic interneurons, and provide the basis for future studies of the circuitry underlying serotonergic modulation of emotional stimulus processing in the amygdala.
Facial masks have become and may remain ubiquitous. Though important for preventing infection, they may also serve as a reminder of the risks of disease. Thus, they may either act as cues for threat, priming avoidance-related behavior, or as cues for a safe interaction, priming social approach. To distinguish between these possibilities, we assessed implicit and explicit evaluations of masked individuals as well as avoidance bias toward relatively unsafe interactions with unmasked individuals in an approach-avoidance task in an online study. We further assessed Covid19 anxiety and specific attitudes toward mask-wearing, including mask effectiveness and desirability, hindrance of communication from masks, aesthetic appeal of masks, and mask-related worrying. Across one sample of younger (18–35 years, N = 147) and one of older adults (60+ years, N = 150), we found neither an average approach nor avoidance bias toward mask-wearing compared to unmasked individuals in the indirect behavior measurement task. However, across the combined sample, self-reported mask-related worrying correlated with reduced avoidance tendencies toward unmasked individuals when Covid19 anxiety was low, but not when it was high. This relationship was specific to avoidance tendencies and was not observed in respect to explicit or implicit preference for mask-wearing individuals. We conclude that unsafe interaction styles may be reduced by targeting mask-related worrying with public interventions, in particular for populations that otherwise have low generalized Covid19 anxiety.
Chronic stress, even stress of a moderate intensity related to daily life, is widely acknowledged to be a predisposing or precipitating factor in neuropsychiatric diseases. There is a clear relationship between disturbances induced by stressful stimuli, especially long-lasting stimuli, and cognitive deficits in rodent models of affective disorders. Regular physical activity has a positive effect on the central nervous system (CNS) functions, contributes to an improvement in mood and of cognitive abilities (including memory and learning), and is correlated with an increase in the expression of the neurotrophic factors and markers of synaptic plasticity as well as a reduction in the inflammatory factors. Studies published so far show that the energy challenge caused by physical exercise can affect the CNS by improving cellular bioenergetics, stimulating the processes responsible for the removal of damaged organelles and molecules, and attenuating inflammation processes. Regular physical activity brings another important benefit: increased stress robustness. The evidence from animal studies is that a sedentary lifestyle is associated with stress vulnerability, whereas a physically active lifestyle is associated with stress resilience. Here, we have performed a comprehensive PubMed Search Strategy for accomplishing an exhaustive literature review. In this review, we discuss the findings from experimental studies on the molecular and neurobiological mechanisms underlying the impact of exercise on brain resilience. A thorough understanding of the mechanisms underlying the neuroprotective potential of preconditioning exercise and of the role of exercise in stress resilience, among other things, may open further options for prevention and therapy in the treatment of CNS diseases.
Objective
In order to optimize psycho‐oncological care, studies that quantify the extent of distress and identify certain risk groups are needed. Among patients with prostate cancer (PCa), findings on depression and anxiety are limited.
Methods
We analyzed data of PCa patients selected from a German multi‐center study. Depression and anxiety were assessed with the PHQ‐9 and the GAD‐7 (cut‐off ≥7). We provided physical symptom burden, calculated absolute and relative risk (AR and RR) of depression and anxiety across patient subsets and between patients and the general population (GP) and tested age as a moderator within the relationship of disease‐specific symptoms with depression and anxiety.
Results
Among 636 participants, the majority reported disease‐specific problems (sexuality: 60%; urination: 52%). AR for depression and anxiety was 23% and 22%, respectively. Significant RR were small, with higher risks of distress in patients who are younger (eg, RR\(_{depression}\) = 1.15; 95%‐CI: 1.06‐1.26), treated with chemotherapy (RR\(_{depression}\)n = 1.46; 95%‐CI: 1.09‐1.96) or having metastases (RR\(_{depression}\) = 1.30; 95%‐CI: 1.02‐1.65). Risk of distress was slightly elevated compared to GP (eg, RR\(_{depression}\) = 1.13; 95%‐CI: 1.07‐1.19). Age moderated the relationship between symptoms and anxiety (B\(_{urination}\) = −0.10, P = .02; B\(_{sexuality}\) = −0.11, P = .01).
Conclusions
Younger patients, those with metastases or treatment with chemotherapy seem to be at elevated risk for distress and should be closely monitored. Many patients suffer from disease‐specific symptom burden, by which younger patients seem to be particularly distressed. Support of coping mechanisms associated with disease‐specific symptom burden seems warranted.
Background: International disease management guidelines recommend the regular assessment of depression and anxiety in heart failure patients. Currently there is little data on the effect of screening for depression and anxiety on the quality of life and the prognosis of heart failure (HF). We will investigate the association between the recognition of current depression/anxiety by the general practitioner (GP) and the quality of life and the patients' prognosis.
Methods/Design: In this multicenter, prospective, observational study 3,950 patients with HF are recruited by general practices in Germany. The patients fill out questionnaires at baseline and 12-month follow-up. At baseline the GPs are interviewed regarding the somatic and psychological comorbidities of their patients. During the follow-up assessment, data on hospitalization and mortality are provided by the general practice. Based on baseline data, the patients are allocated into three observation groups: HF patients with depression and/or anxiety recognized by their GP (P+/+), those with depression and/or anxiety not recognized (P+/-) and patients without depression and/or anxiety (P-/-). We will perform multivariate regression models to investigate the influence of the recognition of depression and/or anxiety on quality of life at 12 month follow-up, as well as its influences on the prognosis (hospital admission, mortality).
Discussion: We will display the frequency of GP-acknowledged depression and anxiety and the frequency of installed therapeutic strategies. We will also describe the frequency of depression and anxiety missed by the GP and the resulting treatment gap. Effects of correctly acknowledged and missed depression/anxiety on outcome, also in comparison to the outcome of subjects without depression/anxiety will be addressed. In case results suggest a treatment gap of depression/anxiety in patients with HF, the results of this study will provide methodological advice for the efficient planning of further interventional research.
Catastrophizing thoughts may contribute to the development of anxiety, but functional emotion regulation may help to improve treatment. No study so far directly compared up- and down-regulation of fear by cognitive reappraisal. Here, healthy individuals took part in a cued fear experiment, in which multiple pictures of faces were paired twice with an unpleasant scream or presented as safety stimuli. Participants (N = 47) were asked (within-subjects) to down-regulate, to up-regulate and to maintain their natural emotional response. Valence and arousal ratings indicated successful up- and down-regulation of the emotional experience, while heart rate and pupil dilation increased during up-regulation, but showed no reduction in down-regulation. State and trait anxiety correlated with evaluations of safety but not threat stimuli, which supports the role of deficient safety learning in anxiety. Reappraisal did not modulate this effect. In conclusion, this study reveals evidence for up-regulation effects in fear, which might be even more efficient than down-regulation on a physiological level and highlights the importance of catastrophizing thoughts for the maintenance of fear and anxiety.
Bei der Entstehung und Aufrechterhaltung von Furcht und Angsterkrankungen stellt, neben der Furchtkonditionierung, die Generalisierung der konditionierten Furcht einen wesentlichen Mechanismus dar. Die der Generalisierung zugrunde liegenden psychologischen und biologischen Prozesse sind jedoch beim Menschen bisher nur wenig untersucht.
Ziel dieser Arbeit war, anhand eines neu entwickelten experimentellen Paradigmas den Einfluss eines psychometrisch bestimmbaren angstspezifischen Faktors sowie der mit Furcht und Angst assoziierten Genotypen Stathmin1, COMT Val158Met und BDNF Val66Met auf die Furchtkonditionierung und Generalisierung konditionierter Furcht zu untersuchen und somit mögliche Risikofaktoren für die Entstehung von Angsterkrankungen zu bestimmen. Hierfür wurden N = 126 gesunde Versuchspersonen (n = 69 weiblich; mittleres Alter M = 23.05, SD = 3.82) für die genannten Polymorphismen genotypisiert und zu ängstlichen und affektiven Symptomen befragt. In einer Akquisitionsphase wurden den Probanden zwei neutrale weibliche Gesichter präsentiert (CS), von denen eines mit einem Schrei sowie einem ängstlichen Gesichtsausdruck (UCS) gepaart wurde. Der sich anschließende Generalisierungstest erfolgte anhand von vier Gesichtern, die in der Ähnlichkeit zwischen den beiden CS schrittweise übergingen. Die Furchtreaktion wurde über die Bewertung von Valenz, Arousal und Kontingenzerwartung sowie über die Hautleitfähigkeitsreaktion (SCR) erfasst.
Die Analyse der Fragebögen anhand einer Hauptachsenanalyse und anhand von Strukturgleichungsmodellen erbrachte eine zweifaktorielle Lösung, die die Konstrukte Depression und Angst abbildete. Nur der Faktor Angst war mit einer veränderten Furchtkonditionierung und Furchtgeneralisierung assoziiert: Hoch Ängstliche zeigten eine stärkere konditionierte Furchtreaktion (Arousal) und wiesen eine stärkere Generalisierung der Valenzeinschätzung und Kontingenzerwartung auf. Für den Stathmin1 Genotyp ergaben sich geschlechtsspezifische Effekte. Bei den männlichen Versuchspersonen zeigte sich in Folge der Akquisition ein stärkerer Abfall der Valenz für den CS+ in der Gruppe der Stathmin1 T Allelträger, die ebenfalls eine stärkere Generalisierung der Furchtreaktion, abgebildet in allen verbalen Maßen, aufwiesen. Ein gegenteiliger Befund ergab sich für die Gruppe der Frauen, insofern eine mit dem Stathmin1 C Allel assoziierte höhere Generalisierung der Valenz, des Arousals und der Kontingenzerwartung festgestellt werden konnte. Für den COMT Val158Met Genotyp ergaben sich keine Einflüsse auf die Akquisition der konditionierten Furcht. Für Träger des COMT 158Val Allels zeigte sich jedoch eine stärkere Generalisierung der Valenz und der Kontingenzerwartung. Auch für den BDNF Val66Met Genotyp konnte keine Veränderung der Furchtakquisition beobachtet werden. Es ergaben sich jedoch Hinweise auf eine erhöhte Generalisierung der Kontingenzerwartung in der Gruppe der BDNF 66Val Homozygoten. Für keinen der beschriebenen Faktoren konnte ein Einfluss auf die Furchtkonditionierung oder deren Generalisierung anhand der SCR abgebildet werden.
Unsere Ergebnisse weisen auf einen psychometrisch erfassbaren Faktor und genetische Einflüsse hin, die über den Prozess einer stärkeren Generalisierung der konditionierten Furcht das Risiko für die Entstehung von Angsterkrankungen erhöhen können. Jedoch sollten die Befunde in größeren Stichproben repliziert werden. Neben der frühzeitigen Identifikation von Risikofaktoren sollten in zukünftigen Studien darüber hinaus wirksame Maßnahmen zur Prävention und Intervention entwickelt werden, um diesem Risiko entgegen zu wirken.
Die Diagnose einer Krebserkrankung und die folgende Therapie mittels Stammzelltransplantation sind ein tiefgreifender Einschnitt in das Leben eines Menschen und können mit erheblicher psychischer Belastung einhergehen, jedoch wird im onkologischen Setting der Frage nach psychischer Belastung oft nur unzureichend nachgegangen. Die vornehmliche Intention dieser Arbeit war es, die Prävalenz von psychischer Belastung in Form von Angst- und depressiver Symptomatik nach allogener Stammzelltransplantation zu ermitteln, zu evaluieren inwiefern die Betroffenen eine adäquate Diagnostik und Behandlung erhalten sowie ferner eine Assoziation des Grades der psychischen Belastung mit soziodemographischen und medizinischen Variablen zu prüfen.
Die Datenerhebung erfolgte in Form einer prospektiv geplanten, non-interventionellen Querschnittsstudie. Der Fallzahlplanung entsprechend wurden konsekutiv 50 Patienten erfasst, welche sich in der ambulanten Nachbetreuung in der Ambulanz für Knochenmarktransplantation des Zentrums für Blutstammzelltransplantation der Medizinischen Klinik und Poliklinik II des Universitätsklinikums Würzburg befanden. 41 Patienten füllten den Fragebogenkatalog, bestehend aus mehreren etablierten Fragebögen, aus. Die Ausprägung der Symptomatik von Angst und Depression wurde anhand verschiedener Selbstbeurteilungs-Fragebögen bewertet. Hierzu dienten das Modul für generalisierte Angststörungen (GAD-7) und für depressive Erkrankungen (PHQ-9) des Gesundheitsfragebogens für Patienten und die kurze Version des Progredienzangst-Fragebogens (PA-F –KF). Das durchschnittliche Alter der Teilnehmer betrug 53 Jahre (21-74 Jahre). Der Mittelwert der Zeit zwischen allogener Stammzelltransplantation und der Studie betrug 614 Tage. Insgesamt 16 (39%) Patienten galten nach den genannten Definitionen als psychisch belastet. 11 dieser Patienten zeigten Symptome einer generalisierten Angststörung, 12 davon litten unter Progredienzangst und 11 Patienten zeigten Symptomatik einer Depression. Jüngeres Alter unter 55 Jahren war signifikant assoziiert mit erhöhter Progredienzangst. Nur wenige der als psychisch belastet definierten Patientin befanden sich in fachspezifischer Betreuung.
Die vorliegende Arbeit zeigt auf, dass Patienten nach allogener Stammzelltransplantation häufig von psychischer Belastung betroffen sind und nur selten professionelle fachspezifische Unterstützung erhalten. Die Erfassung der psychosozialen Belastung nach einer allogenen Stammzelltransplantation sowie die Kenntnis der Auswirkungen auf den Krankheitsverlauf und die Lebensqualität eines Patienten kann genutzt werden für eine Integration der psychoonkologischen Therapie als Säule einer ganzheitlichen Behandlung im Rahmen der Stammzelltransplantation vor dem Hintergrund der Gewährleistung einer medizinisch sowie ökonomisch und menschlich optimierten Patientenversorgung.
Purpose
Growing evidence implies that transition to parenthood triggers symptoms of mental burden not only in women but likewise in men, especially in high-risk pregnancies. This is the first study that examined and compared the prevalence rates of depression, anxiety, and somatic symptom burden of expectant fathers who face different risk situations during pregnancy.
Methods
Prevalence rates of paternal depression (Edinburgh postnatal depression scale), anxiety (generalized anxiety disorder seven), and somatic symptom burden (somatic symptom scale eight) were examined in two risk samples and one control group in the third trimester of their partners’ pregnancy: risk sample I (n = 41) consist of expectant fathers whose partners were prenatally hospitalized due to medical complications; risk sample II (n = 52) are fathers whose partners were prenatally mentally distressed; and control group (n = 70) are those non-risk pregnancies.
Results
On a purely descriptive level, the data display a trend of higher symptom burden of depression, anxiety, and somatic symptoms in the two risk samples, indicating that expectant fathers, whose pregnant partners were hospitalized or suffered prenatal depression, were more prenatally distressed. Exploratory testing of group differences revealed an almost three times higher prevalence rate of anxiety in fathers whose partner was hospitalized (12.2%) compared to those non-risks (4.3%).
Conclusion
Results underline the need for screening implementations for paternal prenatal psychological distress, as well as specific prevention and treatment programs, especially for fathers in risk situations, such as their pregnant partners’ prenatal hospitalization.
The study was registered with the German clinical trials register (DRKS00020131) on 2019/12/09.
Background: The rapid progress of psychosomatic research in cardiology and also the increasing impact of psychosocial issues in the clinical daily routine have prompted the Clinical Commission of the German Heart Society (DGK) to agree to an update of the first state of the art paper on this issue which was originally released in 2008.
Methods: The circle of experts was increased, general aspects were implemented and the state of the art was updated. Particular emphasis was dedicated to coronary heart diseases (CHD), heart rhythm diseases and heart failure because to date the evidence-based clinical knowledge is most advanced in these particular areas. Differences between men and women and over the life span were considered in the recommendations as were influences of cognitive capability and the interactive and synergistic impact of classical somatic risk factors on the affective comorbidity in heart disease patients.
Results: A IA recommendation (recommendation grade I and evidence grade A) was given for the need to consider psychosocial risk factors in the estimation of coronary risks as etiological and prognostic risk factors. Furthermore, for the recommendation to routinely integrate psychosocial patient management into the care of heart surgery patients because in these patients, comorbid affective disorders (e.g. depression, anxiety and post-traumatic stress disorder) are highly prevalent and often have a malignant prognosis. A IB recommendation was given for the treatment of psychosocial risk factors aiming to prevent the onset of CHD, particularly if the psychosocial risk factor is harmful in itself (e.g. depression) or constrains the treatment of the somatic risk factors. Patients with acute and chronic CHD should be offered anti-depressive medication if these patients suffer from medium to severe states of depression and in this case medication with selective reuptake inhibitors should be given. In the long-term course of treatment with implanted cardioverter defibrillators (ICDs) a subjective health technology assessment is warranted. In particular, the likelihood of affective comorbidities and the onset of psychological crises should be carefully considered.
Conclusions: The present state of the art paper presents an update of current empirical evidence in psychocardiology. The paper provides evidence-based recommendations for the integration of psychosocial factors into cardiological practice and highlights areas of high priority. The evidence for estimating the efficiency for psychotherapeutic and psychopharmacological interventions has increased substantially since the first release of the policy document but is, however, still weak. There remains an urgent need to establish curricula for physician competence in psychodiagnosis, communication and referral to ensure that current psychocardiac knowledge is translated into the daily routine.
Epigenetic mechanisms have been proposed to mediate fear extinction in animal models. Here, MAOA methylation was analyzed via direct sequencing of sodium bisulfite-treated DNA extracted from blood cells before and after a 2-week exposure therapy in a sample of n = 28 female patients with acrophobia as well as in n = 28 matched healthy female controls. Clinical response was measured using the Acrophobia Questionnaire and the Attitude Towards Heights Questionnaire. The functional relevance of altered MAOA methylation was investigated by luciferase-based reporter gene assays. MAOA methylation was found to be significantly decreased in patients with acrophobia compared with healthy controls. Furthermore, MAOA methylation levels were shown to significantly increase after treatment and correlate with treatment response as reflected by decreasing Acrophobia Questionnaire/Attitude Towards Heights Questionnaire scores. Functional analyses revealed decreased reporter gene activity in presence of methylated compared with unmethylated pCpGfree_MAOA reporter gene vector constructs. The present proof-of-concept psychotherapy-epigenetic study for the first time suggests functional MAOA methylation changes as a potential epigenetic correlate of treatment response in acrophobia and fosters further investigation into the notion of epigenetic mechanisms underlying fear extinction.
This study examined the impact of three clinical psychological variables (non-pathological levels of depression and anxiety, as well as experimentally manipulated mood) on fat and taste perception in healthy subjects. After a baseline orosensory evaluation, ‘sad’, ‘happy’ and ‘neutral’ video clips were presented to induce corresponding moods in eighty participants. Following mood manipulation, subjects rated five different oral stimuli, appearing sweet, umami, sour, bitter, fatty, which were delivered at five different concentrations each. Depression levels were assessed with Beck’s Depression Inventory (BDI) and anxiety levels were assessed via the Spielberger’s STAI-trait and state questionnaire. Overall, subjects were able to track the concentrations of the stimuli correctly, yet depression level affected taste ratings. First, depression scores were positively correlated with sucrose ratings. Second, subjects with depression scores above the sample median rated sucrose and quinine as more intense after mood induction (positive, negative and neutral). Third and most important, the group with enhanced depression scores did not rate low and high fat stimuli differently after positive or negative mood induction, whereas, during baseline or during the non-emotional neutral condition they rated the fat intensity as increasing with concentration. Consistent with others’ prior observations we also found that sweet and bitter stimuli at baseline were rated as more intense by participants with higher anxiety scores and that after positive and negative mood induction, citric acid was rated as stronger tasting compared to baseline. The observation that subjects with mild subclinical depression rated low and high fat stimuli similarly when in positive or negative mood is novel and likely has potential implications for unhealthy eating patterns. This deficit may foster unconscious eating of fatty foods in sub-clinical mildly depressed populations.
