long-term follow-up of psychogenic pseudosyncope

Objective: To determine the outcome of patients with psychogenic pseudosyncope (PPS) aftercommunication of the diagnosis.Methods: This was a retrospective cohort study of patients with PPS referred in 2007 to 2015 toa tertiary referral center for syncope. We reviewed patient records and studied attack frequency,factors affecting attack frequency, health care use, and quality of life using a questionnaire. Weexplored influences on attack freedom and attack frequency in the 6 months before follow-up forage, sex, education level, duration until diagnosis, probability of diagnosis, additional syncope,and acceptance of diagnosis.Results: Forty-seven of 57 patients with PPS could be traced, of whom 35 (74%) participated.Twelve (34%) were attack-free for at least 6 months. The median time from diagnosis tofollow-up was 50 months (range 6–103 months). Communicating and explaining the diagnosisresulted in immediate reduction of attack frequency (p 5 0.007) from the month before diagnosis(median one attack, range 0–156) to the month after (median one attack, range 0–16). In the6 months before follow-up, the number of admissions decreased from 19 of 35 to 0 of 35 (p 50.002). The use of somatic and mental health care shifted toward the latter (p , 0.0001). Qualityof life at follow-up (Short Form Health Survey 36) showed lower scores for 7 of 8 domainscompared to matched Dutch control values; quality of life was not influenced by attack freedom.Conclusions: After communication of the diagnosis in PPS, attack frequency decreased andhealth care use shifted toward mental care. Low quality of life underlines that PPS is a serious condition. Paroxysmal Cerebral Disorder

Treatment course comparison between anxiety-related disorders in adult outpatients: a Leiden routine outcome monitoring study

Anxiety-related disorders constitute the leading prevalent mental disorders, with major burden on patients, their relatives, and society. Moreover, there is considerable treatment nonadherence/nonresponse. We used routine outcome monitoring (ROM) data from outpatients covering four anxiety-related disorders (DSM-IV-R, N = 470) to examine their 6-month treatment course and its predictors: generalized anxiety disorder, panic disorder with agoraphobia, obsessive-compulsive disorder, and posttraumatic stress disorder. Measures included Mini-International Neuropsychiatric Interview Plus, Brief Symptom Inventory (BSI), Montgomery-Åsberg Depression Rating Scale (MADRS), Brief Anxiety Scale (BAS), and Short Form Health Survey 36 (SF-36). On the clinician-rated instruments (MADRS/BAS), all anxiety-related disorder groups showed a significant albeit modest improvement after treatment. On the BSI self-rating, only generalized anxiety disorder and posttraumatic stress disorder showed a significant modest improvement. No anxiety-related disorder groups improved significantly regarding SF-36 physical functioning. For BSI symptom course, significant predictors were comorbid somatoform/total disorders, SF-36 physical functioning/general health, and MADRS score. Clinical implications and future research recommendations are discussed. Stress-related psychiatric disorders across the life spa

Dynamic time warp analysis of individual symptom trajectories in depressed patients treated with electroconvulsive therapy

Background: Although electroconvulsive therapy (ECT) effectively improves severity scores of depression, its effects on its individual symptoms has scarcely been studied. We aimed to study which depressive symptom trajectories dynamically cluster together in individuals as well as groups of patients during ECT using Dy-namic Time Warp (DTW) analysis.Methods: We analysed the standardized weekly scores on the 25-item abbreviated version of the Comprehensive Psychopathological Rating Scale (CPRS) in depressed patients before and during their first six weeks of ECT treatment. DTW analysis was used to analyse the (dis)similarity of time series of items scores at the patient level (300 'DTW distances' per patient) as well as on the group level. Hierarchical cluster, network, and Distatis analyses yielded symptom dimensions.Results: We included 133 patients, 64.7% female, with an average age of 60.4 years (SD 15.1). Individual DTW distance matrices and networks revealed marked differences in hierarchical and network clusters among patients. Based on cluster analyses of the aggregated matrices, four symptom clusters emerged. In patients who reached remission, the average DTW distance between their symptoms was significantly smaller than non-remitters, reflecting denser symptom networks in remitters than non-remitters (p=0.04).Limitations: The assessments were done only weekly during the first six weeks of ECT treatment. The use of individual items of the abbreviated CPRS may have led to measurement error as well as floor and ceiling effects.Conclusion: DTW offers an efficient new approach to analyse symptom trajectories within individuals as well as groups of patients, aiding personalized medicine of psychopathology.Stress-related psychiatric disorders across the life spa

Narrative Exposure Therapy for Posttraumatic Stress Disorder associated with repeated interpersonal trauma in patients with Severe Mental Illness: a mixed methods design

Background: In the Netherlands, most patients with severe mental illness (SMI) receive flexible assertive community treatment (FACT) provided by multidisciplinary community mental health teams. SMI patients with comorbid posttraumatic stress disorder (PTSD) are sometimes offered evidence-based trauma-focused treatment like eye movement desensitization reprocessing or prolonged exposure. There is a large amount of evidence for the effectiveness of narrative exposure therapy (NET) within various vulnerable patient groups with repeated interpersonal trauma. Some FACT-teams provide NET for patients with comorbid PTSD, which is promising, but has not been specifically studied in SMI patients. Objectives: The primary aim is to evaluate NET in SMI patients with comorbid PTSD associated with repeated interpersonal trauma to get insight into whether (1) PTSD and dissociative symptoms changes and (2) changes occur in the present SMI symptoms, care needs, quality of life, global functioning, and care consumption. The second aim is to gain insight into patients’ experiences with NET and to identify influencing factors on treatment results. Methods: This study will have a mixed methods convergent design consisting of quantitative repeated measures and qualitative semi-structured in-depth interviews based on Grounded Theory. The study population will include adult SMI outpatients (n=25) with comorbid PTSD and receiving NET. The quantitative study parameters will be existence and severity of PTSD, dissociative, and SMI symptoms; care needs; quality of life; global functioning; and care consumption. In a longitudinal analysis, outcomes will be analyzed using mixed models to estimate the difference in means between baseline and repeated measurements. The qualitative study parameters will be experiences with NET and perceived factors for success or failure. Integration of quantitative and qualitative results will be focused on interpreting how qualitative results enhance the understanding of quantitative outcomes. Discussion: The results of this study will provide more insight into influencing factors for clinical changes in this population

The rapid atmospheric monitoring system of the Pierre Auger Observatory

The Pierre Auger Observatory is a facility built to detect air showers produced by cosmic rays above 10(17) eV. During clear nights with a low illuminated moon fraction, the UV fluorescence light produced by air showers is recorded by optical telescopes at the Observatory. To correct the observations for variations in atmospheric conditions, atmospheric monitoring is performed at regular intervals ranging from several minutes (for cloud identification) to several hours (for aerosol conditions) to several days (for vertical profiles of temperature, pressure, and humidity). In 2009, the monitoring program was upgraded to allow for additional targeted measurements of atmospheric conditions shortly after the detection of air showers of special interest, e. g., showers produced by very high-energy cosmic rays or showers with atypical longitudinal profiles. The former events are of particular importance for the determination of the energy scale of the Observatory, and the latter are characteristic of unusual air shower physics or exotic primary particle types. The purpose of targeted (or 'rapid') monitoring is to improve the resolution of the atmospheric measurements for such events. In this paper, we report on the implementation of the rapid monitoring program and its current status. The rapid monitoring data have been analyzed and applied to the reconstruction of air showers of high interest, and indicate that the air fluorescence measurements affected by clouds and aerosols are effectively corrected using measurements from the regular atmospheric monitoring program. We find that the rapid monitoring program has potential for supporting dedicated physics analyses beyond the standard event reconstruction

Techniques for measuring aerosol attenuation using the Central Laser Facility at the Pierre Auger Observatory

The Pierre Auger Observatory in Malargüe, Argentina, is designed to study the properties of ultra-high energy cosmic rays with energies above 10(18) eV. It is a hybrid facility that employs a Fluorescence Detector to perform nearly calorimetric measurements of Extensive Air Shower energies. To obtain reliable calorimetric information from the FD, the atmospheric conditions at the observatory need to be continuously monitored during data acquisition. In particular, light attenuation due to aerosols is an important atmospheric correction. The aerosol concentration is highly variable, so that the aerosol attenuation needs to be evaluated hourly. We use light from the Central Laser Facility, located near the center of the observatory site, having an optical signature comparable to that of the highest energy showers detected by the FD. This paper presents two procedures developed to retrieve the aerosol attenuation of fluorescence light from CLF laser shots. Cross checks between the two methods demonstrate that results from both analyses are compatible, and that the uncertainties are well understood. The measurements of the aerosol attenuation provided by the two procedures are currently used at the Pierre Auger Observatory to reconstruct air shower data

Multi-ancestry study of blood lipid levels identifies four loci interacting with physical activity

Many genetic loci affect circulating lipid levels, but it remains unknown whether lifestyle factors, such as physical activity, modify these genetic effects. To identify lipid loci interacting with physical activity, we performed genome-wide analyses of circulating HDL cholesterol, LDL cholesterol, and triglyceride levels in up to 120,979 individuals of European, African, Asian, Hispanic, and Brazilian ancestry, with follow-up of suggestive associations in an additional 131,012 individuals. We find four loci, in/near CLASP1, LHX1, SNTA1, and CNTNAP2, that are associated with circulating lipid levels through interaction with physical activity; higher levels of physical activity enhance the HDL cholesterol-increasing effects of the CLASP1, LHX1, and SNTA1 loci and attenuate the LDL cholesterol- increasing effect of the CNTNAP2 locus. The CLASP1, LHX1, and SNTA1 regions harbor genes linked to muscle function and lipid metabolism. Our results elucidate the role of physical activity interactions in the genetic contribution to blood lipid levels
