[Implementation of Continuity of Care in Everyday Care - A Comparison Between two Psychiatric Hospitals].

Objective: The rigid separation of outpatient and inpatient care in the German health care system prevents continuity of care, although it has been shown to be of great importance for psychiatric patients. This study analyzes continuity of care of a model hospital with a global treatment budget according to § 64b SGB V and constant treatment staff across all settings in comparison to a control hospital with regular financing without such a team.

Methods: In a prospective cohort study with a 20-month observation period, we collected data on continuity of care of 220 model and 215 control clinic patients.

High frequency repetitive transcranial magnetic stimulation (rTMS) reduces EEG-hypofrontality in patients with schizophrenia.

The reduced metabolic activity in the prefrontal brain lobes, so-called hypofrontality, is associated with increased electrophysiological delta-band activity. Schizophrenia inpatients (N=35) received sham-controlled 10Hz rTMS over the left dorsolateral prefrontal cortex in a randomised design. After treatment, the resting electroencephalography revealed a significant decrease in the delta-band activity, which originated in the right prefrontal cortex and correlated with improvements in facial affect recognition.

Cardiovascular adverse reactions during antidepressant treatment: a drug surveillance report of German-speaking countries between 1993 and 2010.

Background: Antidepressants (ADs) are known to have the potential to cause various cardiovascular adverse drug reactions (ADRs). The tricyclic antidepressants (TCAs) were first revealed to be a possible source of cardiovascular ADRs. In recent years, newer classes of ADs were also suggested to have a higher risk of cardiovascular adverse effects.

Repetitive transcranial magnetic stimulation (rTMS) improves facial affect recognition in schizophrenia.

Objective: Facial affect recognition, a basic building block of social cognition, is often impaired in schizophrenia. Poor facial affect recognition is closely related to poor functional outcome; however, neither social cognitive impairments nor functional outcome are sufficiently improved by antipsychotic drug treatment alone. Adjunctive repetitive transcranial magnetic stimulation (rTMS) has been shown to enhance cognitive functioning in both healthy individuals and in people with neuropsychiatric disorders and to ameliorate clinical symptoms in psychiatric disorders, but its effects on social cognitive impairments in schizophrenia have not yet been studied.

Can an early weight management program (WMP) prevent olanzapine (OLZ)-induced disturbances in body weight, blood glucose and lipid metabolism? Twenty-four- and 48-week results from a 6-month randomized trial.

Objectives: This study was designed to investigate whether a preventive weight management program (WMP) reduces weight gain during olanzapine (OLZ) treatment. Moreover, we examined the effects of intervention on metabolic parameters.

Methods: Patients (N = 100) with schizophrenia or schizoaffective disorder (DSM-IV) who had commenced treatment with OLZ were recruited.

Clomipramine-induced serum prolactin as a marker for serotonin and dopamine turnover: results of an open label study.

Central nervous system (CNS) monoamine deficits have been linked to a number of pathological conditions such as major depressive disorder. Individual biological variations in 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA) and 3-methoxy-4-hydroxyphenylglycol (MHPG) might account for the variation in responses of neurotransmitter systems observed after the administration of clomipramine. The prolactin response to clomipramine has been widely used to assess CNS functioning.

Effects of 10 Hz repetitive transcranial magnetic stimulation (rTMS) on clinical global impression in chronic schizophrenia.

Unlabelled: We conducted a randomized, sham-controlled repetitive transcranial magnetic stimulation (rTMS) study in chronic schizophrenia in-patients (n=35) to evaluate the therapeutic efficacy of 10 Hz stimulation. Patients, who were on stable antipsychotic treatment, were randomly assigned to the active or sham condition. In the active rTMS group, ten sessions with a total of 10,000 stimuli were applied over the left dorsolateral prefrontal cortex at 110% of motor threshold.

Is successful electroconvulsive therapy related to stimulation of the vagal system?

Background: Electroconvulsive therapy (ECT) has been shown to exhibit strong beneficial effects in the treatment of major depressive disorder (MDD). While the exact underlying mechanisms are under debate, a role for the sympathetic response upon ECT has been suggested. When assessing patients with MDD for autonomic function, however, a loss of vagal function is prominent.

Acute effects of sildenafil on flow mediated dilatation and cardiovascular autonomic nerve function in type 2 diabetic patients.

Background: Sildenafil, frequently used as on demand medication for the treatment of erectile dysfunction (ED), has been suggested to improve endothelial function but also to alter blood pressure (BP) and induce sympathetic activation. In people with type 2 diabetes mellitus (T2DM), a high-risk population, the safety profile and the effects on endothelial function of a maximal sildenafil dose (100 mg) have not been investigated and therefore constituted the aim of our study.

Methods: A double-blind, placebo-controlled, cross-over trial using a single dose of 100 mg sildenafil or placebo has been conducted in 40 subjects with T2DM without known CVD.

Increased vagal modulation in atopic dermatitis.

Background: Atopic dermatitis has been shown to be associated with neurogenic and psychosocial factors. In related atopic diseases such as rhinitis or asthma, a shift in autonomic balance towards a parasympathetic modulation has been described. On the other hand, the psychiatric symptoms known for atopic dermatitis are often associated with decreased vagal modulation.

The interaction between pupil function and cardiovascular regulation in patients with acute schizophrenia.

Objective: Cardiac autonomic dysregulation has been reported in patients with schizophrenia. However, there are no definite data examining whether other branches of the autonomic nervous system are compromised as well and how they interrelate with cardiac function. In this study, we tested the hypothesis that the autonomic dysregulation at the heart is reflected in the regulation of the pupillary light reflex.

The effects of sildenafil on heart rate variability in healthy subjects.

The effects of sildenafil on heart rate variability were investigated in 20 healthy male subjects aged 24 (21 to 32) years (median; range). Subjects orally received single 100-mg doses of sildenafil and placebo under randomized double-blind crossover conditions on 2 separate study days. Time domain measures of heart rate variability were assessed under conditions of relaxed rest, metronomic breathing (6 cycles per minute), and bicycle ergometry before administration of sildenafil and placebo as well as 60 minutes afterwards.

[Psychosocial problems and mental disorders among immigrants of German origin].

Objective: The number of ethnic German immigrants from former East bloc countries (Aussiedler) has considerably increased during the past 20 years. However, studies on the frequency of psychiatric disorders or on psychosocial risk factors for psychiatric morbidity in this partially inhomogenous population group are remarkably rare.

Method: We undertook a comprehensive research of the current literature to gain the first systematic review on this issue.

Volume deficits of subcortical nuclei in mood disorders A postmortem study.

Structural changes in subcortical nuclei may underlie clinical symptoms of mood disorders. The goal was to determine whether macrostructural changes exist in brain areas assumed to be involved in regulation of mood and whether such changes differ between major depressive disorder and bipolar disorder. A case-control design was used to compare volumes of all major subcortical nuclei.

Reversible neutropenia during treatment with olanzapine: three case reports.

Olanzapine is an atypical antipsychotic with a low incidence of extrapyramidal-motoric side effects. Its chemical structure is related to clozapine, which is known to induce neutropenia in up to 3% and agranulocytosis in approximately 1% of patients. It has been discussed controversially whether olanzapine also has a potential to induce neutropenia and agranulocytosis.

A functional-structural model to understand cardiac autonomic nervous system (ANS) dysregulation in affective illness and to elucidate the ANS effects of antidepressive treatment.

Numerous studies provide evidence that major depression (MD) is associated with certain disorders of cardiac autonomic nervous system (ANS) function, in particular, with an autonomic neurocardiac imbalance characterized by a low cardiovagal modulation, a raised sympathetic nerve activity and a high resting heart rate. We assume that such MD-associated cardiac ANS disorders are mainly caused by functional-structural abnormalities within the central autonomic network (CAN), in particular, by well-defined abnormalities of hypothalamic structures in MD. In view of the well-known association between an autonomic neurocardiac imbalance and the risk for cardiac arrhythmias, we assume that MD-associated cardiac ANS disorders are at least partly responsible for the high cardiovascular mortality risk in MD.

Relationship between major depression and heart rate variability. Clinical consequences and implications for antidepressive treatment.

A high sympathetic and/or a low cardiovagal activity in patients with major depression (MD) may contribute to the higher cardiac morbidity and mortality of MD patients. Standardized tests of heart rate variability (HRV) allow a quantitative estimation of autonomic nervous system function. However, previous studies on the relationship between HRV and MD have revealed conflicting results.

Effects of reboxetine, a selective norepinephrine reuptake inhibitor, on sympathetic and parasympathetic outflow to the heart: preliminary data.

Rationale: Antidepressants exert distinct effects on cardiac autonomic nervous system (ANS) function, depending on their receptor profile. Reboxetine is a selective norepinephrine (NE) reuptake inhibitor and shows only low affinity for adrenergic and muscarinic receptors. Data on reboxetine's effects on ANS function in patients with major depression (MD) are sparse.

Short-term effects of intravenous benzodiazepines on autonomic neurocardiac regulation in humans: a comparison between midazolam, diazepam, and lorazepam.

Objectives: To evaluate the effects of intravenously applied diazepam, lorazepam, and midazolam on autonomic neurocardiac regulation assessed by standardized measurements of heart rate variability.

Design: Prospective, randomized clinical study.

Setting: University teaching hospital.
