Frequency and correlates of anxiety symptoms during the COVID-19 pandemic in low- and middle-income countries: A multinational study
2021
Objective Studies have documented the significant direct and indirect psychological, social, and economic consequences of the Coronavirus disease 2019 (COVID-19) in many countries but little is known on its impact in low- and middle-income countries (LMICs) already facing difficult living conditions and having vulnerable health systems that create anxiety in individuals for themselves and their loved ones. Using a multinational convenience sample from four LMICs (DR Congo, Haiti, Rwanda, and Togo), this study aims to explore the prevalence of anxiety symptoms and associated risk and protective factors during the COVID-19 pandemic. Methods A total of 1222 individuals (40.9% of women) complet…
Acceptability, attitudes and knowledge towards Transcranial Magnetic Stimulation (TMS) among psychiatrists in France
2020
Abstract Background Non-invasive brain stimulation techniques are becoming a part of psychiatrists’ therapeutic arsenal. Proof of TMS effectiveness and its indications are becoming clearer. While international recommendations exist, and many countries have already recognized the use of these techniques, the French situation is peculiar since no recommendation has been published by the High Authority of Health. Consequently, those techniques are not reimbursed by the healthcare service, few practitioners are trained, some are criticized for using it, and practices remain very heterogeneous. It is therefore important to investigate what slows down the development of these techniques. The obje…
A study on sexual functioning in adults with attention‐deficit/hyperactivity disorder
2020
PURPOSE Sexual dysfunction has been ignored in adults with attention-deficit hyperactivity disorder (A-ADHD). This study examined sexual function in adults with ADHD compared to a healthy control group. DESIGN AND METHODS The experimental group (N = 63, mean age = 31.11 ± 4.29, females = 31) were recruited among referrals with ADHD to an outpatient A-ADHD clinic. The DIVA-2 (Diagnostic Interview for ADHD in adults) and the schedule for affective disorders and schizophrenia (SADS) were used to assess for A-ADHD and comorbid psychiatric disorders, respectively. The healthy groups (N = 66, mean age = 31.37 ± 4.30, females = 31) were demographically matched and had no psychiatric disorders base…
The effects of light exposure on the cortisol stress response in human males.
2020
It is assumed that the production of cortisol is modulated by light exposure. While initial evidence supports this principal effect, the specific effect of light (intensity and wavelength) onto the cortisol stress response is still not completely understood. One between-subject experiment was conducted in a standardized sleep laboratory setting to investigate the effect of light intensity (dim white vs. bright white light) and spectral composition (red vs. blue) on the cortisol response after the Maastricht Acute Stress Test (MAST). 112 healthy young males (24.83 ± 4.10 years of age) were randomly assigned to one of the four light conditions. Across conditions, light exposure was conducted …
Assessing the antecedents and consequences of threat appraisal of an acute psychosocial stressor: the role of optimism, displacement behavior, and ph…
2018
The feeling of stress is increasing in today's societies, particularly in young adults subjected to social evaluative situations in highly competitive academic and work contexts. Threat appraisal is a primary and fundamental reaction when people face a stressful situation. The aim of this study was to investigate the role of dispositional optimism as an antecedent and displacement behavior as a consequence of threat appraisal of a social-evaluative situation of stress. A second objective was to verify the moderating role of physiological responses to stress (heart rate and cortisol reactivity) in the relationship between threat appraisal and displacement behavior. To do this, we combined th…
Blood endocannabinoid levels in patients with panic disorder.
2020
Abstract Background The development and maintenance of anxiety disorders is not fully understood. There is consensus in the literature that in addition to genetic factors, social, psychological and neurobiological factors are of crucial importance. The present exploratory study investigates the influence of the endocannabinoids (EC) and related N-acylethanolamines (NA) on the maintenance of panic disorder (PD). Methods A total of n = 36 PD and n = 26 healthy controls (HC) were included in the study. Baseline characteristics showed no differences between the two groups. The participants were exposed to the Trier Social Stress Test (TSST) for reliable laboratory stress induction. Blood sample…
Comparison of Cortisol Stress Response in Patients with Panic Disorder, Cannabis-Induced Panic Disorder, and Healthy Controls
2018
<b><i>Background/Aims:</i></b> Little research effort has so far been dedicated to the analysis of the hypothalamic-pituitary-adrenal axis of aetiologically differing subgroups of patients with panic disorder (PD). The current study aimed at a deeper understanding of the cortisol stress response in cannabis-induced PD (CIPD) patients. <b><i>Methods:</i></b> Matched groups of 7 PD patients (mean age ± SD: 32.95 ± 9.04 years), 7 CIPD patients (31.94 ± 8.40 years), and 7 healthy controls (HC) (31.13 ± 8.57 years) were included in the study. The Trier Social Stress Test (TSST) was used for stress induction. Salivary cortisol samples were collected…
Intimate partner violence is associated with increased maternal hair cortisol in mother–child dyads
2015
Abstract Background The chronic consequences of intimate partner violence (IPV) on HPA activation are a topic of debate. The current study investigated hair cortisol concentrations in female victims of IPV and their children. Methods A total of 52 mother–child dyads were divided into two groups depending on exposure to IPV: IPV group (n = 27 dyads) and control group (n = 25 dyads). Hair cortisol concentration was measured in 1-cm-long hair strands, representing 30 days of exposure before assessment. PTSD and depression symptoms were assessed in the mother and child. Results Women reporting IPV presented with higher hair cortisol levels, depression and PTSD symptoms severity in comparison to…
Stress-induced pro- and anti-inflammatory cytokine concentrations in panic disorder patients
2018
Abstract Background An attenuated responsivity of the hypothalamus–hypophysis-adrenal (HPA) axis upon challenge and an increased risk for cardiac events are relatively consistent findings in panic disorder (PD) patients. Due to cytokine-HPA interactions, an altered HPA-axis responsivity may be accompanied by altered cytokine concentrations. Immunological reactions under stress might be considered the missing link for explaining an increased cardiac risk. This study analyzed stress-induced cytokine levels in PD patients. Methods A total of n = 32 PD patients and n = 32 healthy control individuals performed the Trier Social Test (TSST). Blood sample collection accompanied the TSST for the col…
Impulsivity and Stress Response in Pathological Gamblers During the Trier Social Stress Test
2017
Gambling has been associated with increased sympathetic nervous system output and stimulation of the hypothalamic–pituitary–adrenal axis. However it is unclear how these systems are affected in pathological gambling. This study aimed to investigate the effect of the Trier Social Stress Test (TSST) on cortisol and on cardiac interbeat intervals in relation to impulsivity, in a sample of male pathological gamblers compared to healthy controls. In addition, we investigated the correlation between the TSST, duration of the disorder and impulsivity. A total of 35 pathological gamblers and 30 healthy controls, ranging from 19 to 58 years old and all male, participated in this study. Stress respon…
