Alterations in the expression of PSA-NCAM and synaptic proteins in the dorsolateral prefrontal cortex of psychiatric disorder patients.
2012
Alterations in the structure and physiology of the prefrontal cortex (PFC) have been found in different psychiatric disorders and some of them involve inhibitory networks, especially in schizophrenia and major depression. Changes in the structure of these networks may be mediated by the polysialylated neural cell adhesion molecule (PSA-NCAM), a molecule related to neuronal structural plasticity, expressed in the PFC exclusively by interneurons. Different studies have found that PSA-NCAM expression in the hippocampus and the amygdala is altered in schizophrenia, major depression and animal models of these disorders, in parallel to changes in the expression of molecules related to inhibitory …
Association of a CB1 Cannabinoid Receptor Gene (CNR1) polymorphism with severe alcohol dependence
2002
Abstract Due to the involvement of the endogenous cannabinoid system in brain reward mechanisms a silent polymorphism (1359G/A; Thr453Thr) in the single coding exon of the CB1 human cannabinoid receptor gene ( CNR1 ) was analysed in 121 severely affected Caucasian alcoholics and 136 most likely non-alcoholic controls. The observed frequency of the A allele was 31.2% for controls and 42.1% for alcoholics with severe withdrawal syndromes ( P =0.010). Post-hoc exploration indicated that this allelic association resulted from an excess of the homozygous A/A genotype in patients with a history of alcohol delirium ( P =0.031, DF 2), suggesting s an increased risk of delirium (OR=2.45, 95% CI 1.14…
Women with borderline personality disorder do not show altered BOLD responses during response inhibition.
2015
Impulsivity is central to borderline personality disorder (BPD). Response inhibition, addressing the ability to suppress or stop actions, is one aspect of behavioral impulse control which is frequently used to assess impulsivity. BPD patients display deficits in response inhibition under stress condition or negative emotions. We assessed whether response inhibition and its neural underpinnings are impaired in BPD when tested in an emotionally neutral setting and when co-morbid attention-deficit/hyperactivity disorder (ADHD) is excluded. To this end, we studied response inhibition in unmedicated BPD patients and healthy controls (HC) in two independent samples using functional magnetic reson…
The impact of exposure to images of ideally thin models in TV commercials on eating behavior: an experimental study with women diagnosed with bulimia…
2011
This study investigates whether eating behavior in women with diagnosed bulimia nervosa is influenced by prior exposure to images of ideally thin models. Twenty-six participants diagnosed with bulimia nervosa (BN) and 30 normal controls (NC) were exposed to body-related and neutral TV commercials; then food that typically triggers binge eating was provided, and the amount of food eaten was measured. No significant difference for food intake between NC and BN could be found, but food intake for BN was predicted by the degree of thoughts related to eating behaviors during exposure to the thin ideal. No impact of general body image or eating pathology on food intake could be found. The results…
Anticipatory effects of food exposure in women diagnosed with bulimia nervosa.
2002
Objective. To investigate cephalic phase responses (CPRs) in women diagnosed with bulimia nervosa and to test the assumption that eating disordered individuals respond with more marked CPRs and higher increases in psychophysiological arousal to the presentation of food cues. Method. Thirteen female inpatients diagnosed with bulimia nervosa were compared to 15 non-eating disordered female volunteers. Participants were exposed to their preferred binge food in a single laboratory session with the possibility to eat immediately after the exposure trial. Results. The results show greater salivation responses to food exposure and lower sympathetic arousal in patients diagnosed with bulimia nervos…
The prevalence of eating disorders in adolescents with idiopathic scoliosis
2008
This study examines the hypothesis of an association between adolescent idiopathic scoliosis (AIS) and eating disorders (EDs). A population of young females affected by AIS has been interviewed for a possible diagnosis of EDs. The proportion of individuals with EDs resulted significantly larger than normative epidemiological data: Prevalences were 9.2% for anorexia nervosa (AN), 7.7% for bulimia nervosa (BN) and 5.3% for eating disorders not otherwise specified (EDNOS). The relationship between EDs and AIS was further tested through a second analysis. Severity of the rachides pathology was correlated with the presence of AN. Our study supports the hypothesis of a comorbidity between AIS and…
Drop-out and treatment outcome of outpatient cognitive-behavioral therapy for anorexia nervosa and bulimia nervosa.
2013
In the present study, drop-out-analyses were carried out for a manual-based cognitive–behavioral therapy for 104 females with anorexia nervosa (AN) and bulimia nervosa (BN), in the service setting of a university outpatient clinic (naturalistic setting). A total of 22.9% of patients with AN terminated therapy prematurely (drop-outs), compared to 40.6% of patients with BN. Group differences between drop-outs and completers show that the group of drop-outs with BN had higher values in the depression score at the start of therapy and was almost two times more likely to have a comorbid disorder (odds ratio 1.69), whereas drop-outs with AN had higher values in the outcome-scale drive for thinnes…
Plasma non-cholesterol sterols in primary hypobetalipoproteinemia
2011
Primary hypobetalipoproteinemia (pHBL) is characterized by plasma cholesterol levels ApoB48, and FHBL harbouring as yet unknown molecular defects. Not linked FHBL kindred are not homogeneous in terms of plasma NCS levels. NCS cannot replace genetic HBL analysis.
Maintenance of weight loss after obesity treatment: is continuous support necessary?
2002
Abstract Objective: This study examined outcome differences of 109 obese subjects, who participated in a 10-week cognitive-behavioral inpatient treatment followed by either a weight maintenance program or a follow-up period without professional support. Methods: Self-rated weight loss, eating behaviors, and general psychopathology were assessed several months before treatment, when subjects were admitted, at discharge, and at the 6-, 12-, and 18-month follow-ups. Structured interviews for mental disorders and eating pathology were conducted additionally. Results: The mean weight of the sample at baseline was 127 kg. Weight loss of the total sample amounted to 8.0 kg (6.3%) and was completel…
Group Therapy Module to Enhance Self-Esteem in Patients with Borderline Personality Disorder: A Pilot Study
2010
Psychotherapeutic treatments of borderline personality disorder (BPD) often focus on severe behavioral problems. Until now, few techniques have been developed to specifically address low self-esteem in BPD. We developed a 6-session psychoeducative group therapy module to treat low self-esteem in BPD patients. After developing and piloting the therapy module, a controlled outpatient pilot study was performed. Nineteen female BPD patients participated in the group module after discharge from an inpatient DBT program. Twenty-four female BPD patients served as controls. Outcome was assessed by different self-esteem measures. Results showed a greater improvement in self-esteem in the interventio…
