To test the potential role of H19 as a tumour suppressor gene we have examined its expression and DNA methylation in Wilms' tumours (WTs). In most WTs (18/25), H19 RNA was reduced at least 20-fold from fetal kidney levels. Of the expression-negative tumours ten retained 11p15.5 heterozygosity: in nine of these, H19 DNA was biallelically hypermethylated and in two cases hypermethylation locally restricted to H19 sequences was also present in the non-neoplastic kidney parenchyma. IGF2 mRNA was expressed in most but not all WTs and expression patterns were consistent with IGF2/H19 enhancer competition without obligate inverse coupling. These observations implicate genetic and epigenetic inactivation of H19 in Wilms' tumorigenesis.
Background: All therapists direct their attention in some manner during psychotherapy. A special form of directing attention, ‘mindfulness’, is recommended. This study aimed to examine whether, and to what extent, promoting mindfulness in psychotherapists in training (PiT) influences the treatment results of their patients. Methods: The therapeutic course and treatment results of 124 inpatients, who were treated for 9 weeks by 18 PiTs, were compared. The PiTs were randomly assigned to 1 of 2 groups: (i) those practicing Zen meditation (MED; n = 9 or (ii) control group, which did not perform meditation (noMED; n = 9). The results of treatment (according to the intent-to-treat principle) were examined using the Session Questionnaire for General and Differen-tial Individual Psychotherapy (STEP), the Questionnaire of Changes in Experience and Behavior (VEV) and the Symptom Checklist (SCL-90-R). Results: Compared to the noMED group (n = 61), the patients of PiTs from the MED group (n = 63) had significantly higher evaluations (according to the intent-to-treat principle) for individual therapy on 2 STEP scales, clarification and problem-solving perspectives. Their evaluations were also significantly higher for the entire therapeutic result on the VEV. Furthermore, the MED group showed greater symptom reduction than the noMED group on the Global Severity Index and 8 SCL-90-R scales, including Somatization, Insecurity in Social Contact, Obsessiveness, Anxiety, Anger/Hostility, Phobic Anxiety, Paranoid Thinking and Psychoticism. Conclusions: This study indicates that promoting mindfulness in PiTs could positively influence the therapeutic course and treatment results in their patients.
In a first cross-validation with 108 patients, some rather high correlations were found between the SCL-90-R and the ISR. They ranged from r = 0.78 to 0.37 for the individual syndrome scales, and amounted to r = 0.78 for the GSI versus the total score.
Anger and aggression are typical in borderline patients. The goal of this study was to compare the efficacy of lamotrigine versus placebo in the treatment of aggression in women meeting the criteria for borderline personality disorder (BPD). We conducted a randomized, double-blind, placebo-controlled study of lamotrigine in 24 female subjects meeting Structured Clinical Interview for DSM-IV (SCID) criteria for BPD. The subjects were randomly assigned in a 2: 1 manner ratio to lamotrigine (n = 18) or placebo (n = 9). Treatment duration was 8 weeks. Primary outcome measures were self-reported changes on the anger scales of the Trait Anger Expression Inventory (STAXI). In comparison with the placebo group, and according to the intention-to-treat principle, highly significant (p < 0.01) changes on four STAXI scales (State-Anger, Trait-Anger, Anger-Out, Anger-Control) were observed in those subjects treated with lamotrigine after 8 weeks. The only exception (p < 0.05) was found on the Anger-In scale, where a difference of only 8.5% (p < 0.2) was found. All the patients tolerated lamotrigine relatively well. Lamotrigine appears to be a safe and effective agent in the treatment of anger in women with criteria-defined BPD as defined by SCID criteria. It did not produce any clinically significant effect on body weight.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
