Center differences and cross-national invariance in help-seeking for panic disorder. A report from the cross-national collaborative panic study.
1992
Help-seeking behaviour for treatment of panic disorder was investigated in the sample of the Cross-National Collaborative Panic Study Second Phase. A total of 1168 patients were entered into this trial in 14 countries. Although there were significant center differences in prior treatment and utilization of health services there were also similarities. Treatment had been provided mainly by general practitioners. Drug treatment consisted mostly of prescription of classical tranquilizers and had a longer duration than treatment by psychotherapy. Patients with agoraphobic avoidance, past major depression and longer duration of illness used medical and psychiatric treatment facilities more inten…
The influence of major histocompatibility complex class II genes and T-cell Vbeta repertoire on response to immunization with HBsAg.
1998
Nonresponsiveness to HBsAg vaccination is observed in 5-10% of vaccine recipients and is possibly caused by a defect in the T helper cell compartment. The immune response to HBsAg is influenced by genes of the major histocompatibility complex. We have investigated MHC class I and class II antigens in 53 adult responders and 73 nonresponders. Results obtained in this first study were tested in a second study with 56 responders and 62 nonresponders from an infant vaccination trial. In addition, the peripheral Vbeta-chain T-cell receptor repertoire was investigated using monoclonal antibodies and flow-cytometry in 26 adult responders and 38 nonresponders. As previously reported, nonresponsiven…
Effects of cognitive behavioral therapy with relaxation vs. imagery rescripting on test anxiety: A randomized controlled trial.
2016
Abstract Background Test anxiety is a common condition in students, which may lead to impaired academic performance as well as to distress. The primary objective of this study was to evaluate the effectiveness of two cognitive-behavioral interventions designed to reduce test anxiety. Test anxiety in the participants was diagnosed as social or specific phobia according to DSM-IV. Subsequently subjects were randomized to three groups: a moderated self-help group, which served as a control group, and two treatment groups, where either relaxation techniques or imagery rescripting were applied. Methods Students suffering from test anxiety were recruited at two German universities ( n =180). The …
A randomized controlled trial of unguided internet cognitive-behavioral treatment for perfectionism in individuals who engage in regular exercise.
2018
OBJECTIVE Clinical perfectionism has been found to be a risk and maintaining factor in eating disorders (EDs), compulsive exercise, and athlete burnout. This study investigated whether an unguided internet cognitive-behavioral treatment (ICBT) for perfectionism would reduce ED pathology, compulsive exercise, and burnout in individuals who engage in regular exercise. METHOD Participants were randomly allocated to intervention (n = 38) or waitlist control (n =29). A generalized linear mixed model (GLMM) analysis was conducted pre and post treatment. A follow-up analysis was conducted with the intervention group at 3 and 6 months. RESULTS The intervention group experienced a significant reduct…
Quantitative and functional analysis of core-specific T-helper cell and CTL activities in acute and chronic hepatitis B
2008
Aims/background CD4+ T-helper cell (Th) responses to hepatitis B virus (HBV) core antigen (HBc) are increased during exacerbations in acute and chronic hepatitis B (AHB, CHB) and might influence the induction of CD8+ cytotoxic T lymphocytes (CTL) that are important for viral clearance. Methods HBc-specific proliferative responses and cytokine release of blood mononuclear cells (PBMC) were studied in patients with AHB or CHB, as well as responders and non-responders to interferon-alpha treatment (IFN-R, IFN-NR), by [3H]-thymidine-uptake, enzyme-linked immunosorbent assay (ELISA) and Elispot assay and were compared to peptide HBc18 27-specific CTL precursor frequencies among CD8+ T cells deri…
T cells involved in psoriasis vulgaris belong to the Th1 subset
1994
Although the pathogenesis of psoriasis vulgaris is still unknown, several characteristics point to an immunologically mediated process. Epidermal psoriatic lesions are characterized by a hyperproliferation of keratinocytes and an infiltration of T lymphocytes and granulocytes. Because the former may be mediated in part by lymphokines secreted by T cells, we have focused our interest on the in vivo and in vitro cytokine secretion patterns of T lymphocytes from psoriatic lesions. In five patients T lymphocytes were obtained from epidermal specimens. The cells were propagated with lectin and irradiated feeder cells and subsequently cloned by limiting dilution. The resulting T-cell clones were …
Don't stress, it's under control: Neural correlates of stressor controllability in humans
2021
Abstract Animal research has repeatedly shown that control is a key variable in the brain's stress response. Uncontrollable stress triggers a release of monoamines, impairing prefrontal functions while enhancing subcortical circuits. Conversely, control over an adverse event involves prefrontally mediated downregulation of monoamine nuclei and is considered protective. However, it remains unclear to what extent these findings translate to humans. During functional magnetic resonance imaging, we subjected participants to controllable and uncontrollable aversive but non-painful electric stimuli, as well as to a control condition without aversive stimulation. In each trial, a symbol signalled …
Liver follicular helper T-cells predict the achievement of virological response following interferon-based treatment in HCV-infected patients.
2012
Background Here, we assessed the presence of intrahepatic follicular helper T-cells (TFH) in a cohort of consecutive genotype 1 (G1) chronic hepatitis C (CHC) patients comprising non-responders (NRs), relapsers (RRs) or those with sustained virological response (SVR) to pegylated interferon and ribavirin, and tested their relation with the response to antiviral treatment. Methods A total of 78 patients with G1 CHC (30 SVR, 15 RR and 33 NR), comparable for sex, age, viral load and fibrosis were evaluated by immunohistochemistry for liver content of PD1+Bcl6+ TFH cells. The number of TFH cells in the immunostained sections was counted out of five representative high-power microscopic fields (…
Peripheral blood dendritic cells are phenotypically and functionally intact in chronic hepatitis B virus (HBV) infection
2007
Summary Persistence of hepatitis B virus (HBV) infection is associated with reduced anti-viral T cell responses. Impaired dendritic cell (DC) function was suggested as the cause of reduced T cell stimulation in chronic HBV carriers. Thus, we compared myeloid (mDC) and plasmacytoid DC (pDC) from chronic HBV carriers and controls. Frequency and phenotype of isolated DC were analysed by fluorescence activated cell sorter staining, DC function by mixed lymphocyte reaction, cytokine bead array, intracellular cytokine staining, enzyme-linked immunosorbent assay and enzyme-linked immunospot. Expression of HBV DNA and mRNA was studied by polymerase chain reaction (PCR). Circulating total DC, mDC or…
Personal stigma and use of mental health services among people with depression in a general population in Finland
2011
Abstract Background A minority of people suffering from depression seek professional help for themselves. Stigmatizing attitudes are assumed to be one of the major barriers to help seeking but there is only limited evidence of this in large general population data sets. The aim of this study was to analyze the associations between mental health attitude statements and depression and their links to actual use of mental health services among those with depression. Methods We used a large cross-sectional data set from a Finnish population survey (N = 5160). Attitudes were measured by scales which measured the belief that people with depression are responsible for their illness and their recove…
