MedicalResearch.com Interview with: Dr Emmanuel Boselli, MD, PhD Anesthesiology and Intensive Care University Claude Bernard Lyon I University of Lyon Lyon, France Medical Research: What is the background for this study? What are the main findings? Dr. Boselli: We hypothesized that the use of conversational hypnosis in patients undergoing regional anesthesia procedures for ambulatory upper limb surgery might provide better comfort than the use of oral premedication during the regional anesthesia procedure. We assessed the subjective effect of conversational hypnosis on a patient self-reported comfort scale ranging from 0 (no comfort) to 10 (maximal comfort), and the objective effect was assessed using the Analgesia/Nociception Index (ANI), a 0-100 index derived from heart rate variability reflecting the relative parasympathetic tone. In our study of 100 patients undergoing hand surgery in two different centers, 50 had conversational hypnosis while being given regional anesthesia (Saint-Grégoire hospital), and 50 were given of oral hydroxyzine 30 minutes to an hour before the regional anesthesia procedure (Lyon hospital). Patients having hypnosis measured an average ANI of 51 before and 78 after hypnosis, whereas those who had premedication averaged 63 before and 70 after. The average comfort scale of those who had received hypnosis was 6.7 before and 9.3 after, while patients who had medication averaged 7.8 before and 8.3 after. The main finding of this study is that conversational hypnosis induced greater increase in comfort scales and ANI values than oral premedication. Medical Research: What is conversational hypnosis? What does it consist of? Dr. Boselli: Conversational hypnosis consists of matching the patient's behavioral communication patterns, reflective listening, avoiding any negative suggestion (e.g. "Keep calm and quiet" instead of "Please don't move!") and focalizing the patient's attention on something else than the regional anesthesia procedure, such as the ultrasound machine screen.

Melinda C Power, ScD Post-Doctoral Research Fellow Epidemiology Department, Johns Hopkins Bloomberg School of Public Health Neurology Department, Johns Hopkins School of MedicineMedicalResearch.com Interview with: Melinda C Power, ScD Post-Doctoral Research Fellow Epidemiology Department, Johns Hopkins Bloomberg School of Public Health Neurology Department, Johns Hopkins School of Medicine Medical Research: What is the background for this study? What are the main findings? Dr. Power: Air pollution may be related to mental health, particularly anxiety, through effects on oxidative stress and systemic inflammation or through promotion or aggravation of chronic diseases.  However, there has been very little research on the relation between air pollution exposures and anxiety in people.   Our study found that those with higher exposures to fine particulate matter, a type of air pollution, were more likely to experience elevated anxiety symptom levels.  Our study also suggests that recent exposures to find particulate matter air pollution are potentially more relevant to anxiety symptom levels than long-term past exposures.

Courtney Benjamin Wolk, Ph.D. Postdoctoral Researcher Center for Mental Health Policy and Services Research Perelman School of Medicine Department of Psychiatry University of Pennsylvania Philadelphia, PA 19104MedicalResearch.com Interview with: Courtney Benjamin Wolk, Ph.D. Postdoctoral Researcher Center for Mental Health Policy and Services Research Perelman School of Medicine Department of Psychiatry University of Pennsylvania Philadelphia, PA 19104 Medical Research: What is the background for this study? What are the main findings? Response: Previous research investigating the relationship between anxiety and suicidality has been mixed. An ongoing question in the field has been whether anxiety disorders independently increase risk for suicidal ideation and behavior or if the high co-occurrence of anxiety and mood symptoms or other shared demographic factors are driving relationships that have been observed between anxiety and suicidality. We examined the relationship between response to treatment for an anxiety disorder in childhood and suicidal ideation, plans, and attempts 7 to 19 years after treatment with cognitive-behavioral therapy, more commonly referred to as CBT. Our results indicated that participants who responded favorably to cognitive-behavioral therapy during childhood had lower rates of lifetime, past month, and past two-week suicidal ideation endorsement than treatment non-responders. This was the case across both self-report and interview-report of suicidal ideation. Treatment response was not significantly associated with suicide plans or attempts, though plans and attempts were infrequently endorsed in our sample, limiting the ability to detect findings.

MedicalResearch.com Interview with: Phil Tully PhD Early Career Research Fellow, Discipline of Medicine University of Adelaide Australia and Abteilung für Rehabilitationspsychologie und Psychotherapie Institut für Psychologie, Universität Freiburg Freiburg Germany Medical Research: What are the main findings of the study? Response: The systematic review indicated that anxiety disorders ascertained by clinical interview are highly prevalent in patients with verified coronary heart disease. Also, approximately 50% of anxiety disorders were comorbid with depression. There was however some uncertainty in prevalence estimates with high level heterogeneity observed between studies. It was also evident that studies measuring generalized anxiety disorder in outpatient samples reported an increased prognostic risk for major adverse cardiac events in the longer term, when adjusted for confounding factors, however there was limited data. There were no randomized controlled trials targeting anxiety disorders in this population. (more…)

Lena Johansson, PhD, MSc, RN Institute of Neuroscience and Physiology Department of Psychiatry and Neurochemistry Sahlgrenska Academy at Gothenburg UniversityMedicalResearch.com Interview with: Lena Johansson, PhD, MSc, RN Institute of Neuroscience and Physiology Department of Psychiatry and Neurochemistry Sahlgrenska Academy at Gothenburg University Medical Research: What are the main findings of the study? Dr. Johansson: We found that a higher degree of neuroticism in midlife was associated with increased risk of Alzheimer’s disease over 38 years. On the 24 point scale, the risk increased with 4% per each step. Women who score high on the neuroticism scale were more likely to experience feelings such as anxiety, nervousness, worry, and irritability, and they were more moodiness and stress-prone. The association between neuroticism and Alzheimer’s disease diminished after adjusting for longstanding perceived distress symptoms, which suggest that the associations was at least partly depended on long-standing distress symptoms. When the two personality dimensions were combined, women with high neuroticism/low extraversion had a double risk of Alzheimer’s disease compared to those with low neuroticism/high extraversion.

MedicalResearch.com Interview with: Dr Oliver J Robinson Ph.D. Section on Neurobiology of Fear and Anxiety, National Institute of Mental Health, NIH, Bethesda, MD, Institute of Cognitive Neuroscience University College London, London, UK Medical Research: What are the main findings of the study? Dr. Robinson: This study is looking at a symptom of anxiety disorders known as “negative affective bias”. This describes the tendency of people with anxiety disorders to focus on negative or threatening information at the expense of positive information. We completed a number of previous studies looking at so called “adaptive” anxiety in healthy individuals – this is the normal, everyday anxiety that everyone experiences; walking home in the dark, for instance (in these prior studies we used unpredictable electrical shocks to make people anxious and stressed). When we made healthy people transiently anxious in this way we showed that this was also associated with negative affective bias and driven by a specific brain circuit: the dorsal medial prefrontal (anterior cingulate) cortex—amygdala aversive amplification circuit. In this study we showed that the same circuit that was engaged by transient anxiety in our healthy sample was actually engaged ‘at baseline’ (i.e. without stress) in our patient group. This suggests that this mechanism which can be temporarily activated in healthy controls becomes permanently ‘switched on’ in our patient group. This might explain why people with anxiety disorders show persistent ‘negative affective biases’. Furthermore, the extent to which this circuit was turned on correlated with self-reported anxiety. That is to say the more anxious an individual said they were, the greater the activity in this circuit. Therefore, there seems to be more of a dimension or scale of anxiety, rather than a simple well/unwell diagnosis. (more…)

Johanna Petzoldt Institute of Clinical Psychology and Psychotherapy Chemnitzer Straße Dresden, GermanyMedicalResearch.com Interview with: Johanna Petzoldt Institute of Clinical Psychology and Psychotherapy Chemnitzer Straße Dresden, Germany MedicalResearch: What are the main findings of the study? Answer: We investigated 286 mother-infant couples from the Maternal Anxiety in Relation to Infant Development (MARI) Study from Dresden (Germany) via standardized interview and questionnaire. We found a robust relation from maternal lifetime anxiety disorders as early as prior to pregnancy to excessive crying in the offspring. Also, the association increased when considering incident anxiety disorders during pregnancy and after delivery. (more…)

Monika Waszczuk 1+3 PhD Student MRC SGDP Research Centre Institute of Psychiatry, King's College London DeCrespigny Park London UKMedicalResearch.com Interview with: Monika Waszczuk 1+3 PhD Student MRC SGDP Research Centre Institute of Psychiatry, King's College London DeCrespigny Park London UK MedicalResearch: What are the main findings of the study? Answer: Little is known about the genetic influences on the relationship between depression and anxiety disorders across development. We used two population-based prospective longitudinal twin and sibling studies to investigate phenotypic associations between the symptoms of these disorders, and tested genetic structures underlying these symptoms across three developmental stages: childhood, adolescence and early adulthood. We found that depression and anxiety disorder symptoms are largely distinct in childhood and are influenced by largely independent genetic factors. Depression and anxiety symptoms become more associated and shared most of their genetic etiology from adolescence. An overarching internalizing genetic factor influencing depression and all anxiety subscales emerged in early adulthood. These results provide preliminary evidence for different phenotypic and genetic structures of internalizing disorder symptoms in childhood, adolescence and young adulthood, with depression and anxiety becoming more associated from adolescence.

Huffman, M.D. Harvard Medical School Department of Psychiatry Massachusetts General Hospital, Boston MedicalResearch.com: What are the main findings of the study? Dr. Huffman: Depression and anxiety in cardiac patients are associated with adverse cardiac outcomes.  We completed a very low-intensity care management intervention to identify depression and anxiety disorders during a cardiac admission and then to assist in the monitoring and management of the condition over the next 24 weeks. There have been other care management trials in cardiac patients, but ours was the first to co-manage depression and anxiety, the first to initiate treatment in the hospital, the first to take a broad population of cardiac patients rather than a single diagnosis, and the first to use such a low-resource strategy with only a single part-time social worker to coordinate care. We found that the care management intervention was associated with significant improvements in mental health treatment, mental health related quality of life, depression, and function at 24 weeks compared to enhanced treatment as usual.  We did not find differences in anxiety, adherence, or cardiac readmissions.

MedicalResearch.com Interview with: Golda Ginsburg, Ph.D Professor Director, Research, Division of Child and Adolescent Psychiatry Department of Psychiatry and Behavioral Sciences The Johns Hopkins University School of Medicine Baltimore, MarylandGolda Ginsburg, Ph.D Professor Director, Research, Division of Child and Adolescent Psychiatry Department of Psychiatry and Behavioral Sciences The Johns Hopkins University School of Medicine Baltimore, Maryland MedicalResearch.com: What are the main findings of the study? Dr Ginsburg: This study examined the long-term outcomes of youth treated for an anxiety disorders. Findings revealed that almost half of anxious youth treated for an anxiety disorder were in remission (i.e., did not meet diagnostic criteria for any of the three study entry anxiety disorders) at an average of six years since starting treatment. Youth showing clinically meaningful improvement after 12 weeks of treatment, were more likely to be in remission, had lower anxiety severity, and had better functioning compared to youth who showed minimal or no initial clinical improvement. Treatment type did not affect long-term outcomes. (more…)
