An abstract of the article "Music for Affect Regulation: Music listening in group receptive music therapy in the treatment of depression," by Meertine M.J. Laansma and P.M. Judith Haffmans is presented.

Abstract: Background: It has frequently been demonstrated that experimental lowering of serotonin (5-HT) neurotransmission by acute tryptophan depletion (ATD) induces a transient depressed mood in 50–60% of patients treated with a selective serotonin reuptake inhibitor (SSRI) who are in remission from depression. In unmedicated depressed patients, ATD has no immediate effect on symptoms. The effects in currently depressed medicated patients have not been investigated. Methods: Fourteen currently depressed patients (seven patients treated with a selective serotonin–noradrenalin reuptake inhibitor (SSNRI); seven other treatment, non-SSNRI) received ATD in a double-blind, crossover design. Different strengths of the ATD mixture (aimed at 50% and 90% reduction of tryptophan) were used on separate days. Psychiatric symptoms were assessed at both sessions prior to, at +6.5 h, and at +24 h after ATD. Results: The ATD mixtures induced the expected reductions of plasma tryptophan levels. Full but not partial depletion improved mood and other psychiatric symptoms at +24 h in patients who received SSNRI treatment, as indicated by clinical ratings and self-report. Subjective sleep quality also improved. Conclusions: The effects of ATD on psychiatric symptoms in currently depressed patients are remarkably different from the results in recently remitted SSRI-treated patients. ATD in currently depressed patients treated with serotonergic antidepressants possibly provides important information about the mechanism of action of SSRIs. [Copyright &y& Elsevier]

The authors studied the coping style of substance-abuse patients during clinical cognitive-behavioral group therapy, and the effects of mood and anxiety disorders on changes in coping style. Change in coping style was studied prospectively in a cohort of 132 residential-drug-abuse patients. In addition to pretreatment assessments, which included diagnosis of mood and anxiety disorders and addiction severity, repeated measurements of coping style were performed at predetoxification, pretreatment, and after three and six months of treatment. Considerable change in coping style between predetoxification and pretreatment was found, suggesting that coping assessment in a predetoxification phase is confounded by state factors surrounding treatment entry. Coping style of detoxified substance abusers is related to the presence of mood and anxiety disorders. Coping style was not found to be related to the severity of drug abuse. Furthermore, maladaptive coping styles decreased after three months of inpatient-substance-abuse treatment, and more-adaptive coping styles remained stable for another three months of inpatient treatment. Patients with an anxiety disorder improved less on coping style when compared to non-anxiety patients. Presence of a mood disorder had no impact on coping-style improvement. The results indicate that more attention should be focused on anxiety disorders during substance-abuse treatment in order to improve coping style. Furthermore, more studies are needed on the relation between substance abuse, coping style, and psychopathology. © 2003 Wiley Periodicals, Inc. J Clin Psychol, 2003. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: The aims of this study were to describe the characteristics of hyponatremia in elderly users of antidepressants, to determine the prevalence and risk factors for hyponatremia, and to identify the underlying mechanisms. Study design: Cross-sectional study (March 2007–April 2009) with prospectively collected data. Patients were older than 60 years, used antidepressants, and had a complete geriatric assessment. Main outcome measures: Serum sodium and antidiuretic hormone levels, serum osmolality, urine sodium level, and urine osmolality were measured. The prevalence of hyponatremia (serum sodium <135mM) as an adverse reaction to an antidepressant (AR-AD), defined with Naranjo's algorithm, was calculated. Hyponatremic patients were compared to normonatremic patients with regard to gender, age, weight, history of hyponatremia, hyponatremia-associated medications and disorders, and type and duration of antidepressant use. Results: Of 358 eligible patients, 345 were included. The prevalence of hyponatremia as an AR-AD was 9.3%. Risk factors were a history of hyponatremia (adjusted OR 11.17, 95%CI 2.56–40.41), weight<60kg (adjusted OR 3.47, 95%CI 1.19–10.13), and psychosis (adjusted OR 3.62, 95%CI 1.12–11.73). Non-suppressed ADH was found in a minority of hyponatremic patients. Conclusions: In elderly patients, the prevalence of hyponatremia as adverse reaction to all types of antidepressants was 9%. Patients with previous hyponatremia, weight <60kg, and psychosis were at risk. Beside SIADH, the nephrogenic syndrome of inappropriate antidiuresis, in which ADH secretion was normal, is postulated as an underlying mechanism. This has consequences for treatment of antidepressant-induced hyponatremia with vasopressin receptor antagonists. [Copyright &y& Elsevier]

Abstract: Background: Prediction of treatment outcome has important clinical consequences. Personality factors have rarely been tested as predictors of acute outcome. Personality, demographic and illness-related characteristics were assessed at baseline for prediction of outcome of treatment in depressed out-patients. Methods: One hundred and ninety-three patients with major depressive disorder (MDD) were enrolled in a 12 to 16 week trial. The treatment consisted of nefazodone, nefazodone in combination with interpersonal psychotherapy (IPT), IPT in combination with placebo and IPT alone. Demographic and illness related variables were collected at baseline. Personality was assessed using the NEO-FFI. This instrument measures five dimensions of personality. A hierarchical logistic regression was carried out to test for significant predictors of remittance. Further a multiple regression analysis was used to investigate variables predictive of changes on the Hamilton Depression Rating Scale as dependent variable. Results: Univariate analysis showed a significant relationship of outcome with severity, duration of index episode, and use of medical services (UMS). None of the personality variables was predictive of outcome. Regression analyses showed that these disease related variables each uniquely predicted outcome, but that personality factors did not significantly contribute to the prediction model. Limitations: The study was carried out in secondary and tertiary care centers and may not be generalizable to other populations. Personality dimensions were assessed with a self-report instrument and may be prone to bias. Conclusions: Severity and duration of the index episode, and to a lesser extent, UMS, and not personality factors, predict outcome in the short term treatment of MDD. [Copyright &y& Elsevier]

Background: Depression is a major risk factor for cardiovascular disease. An important risk factor for cardiovascular disease, low heart rate variability, often has been found in depressed patients and has been associated with impulsivity. The present study investigated whether experimental lowering of serotonin would decrease heart rate variability and increase impulsivity in remitted depressed patients, in particular in those patients with disturbed impulse control. Methods: Nineteen patients in remission from depression received high-dose and low-dose acute tryptophan depletion in a randomized, counterbalanced, double-blind crossover design. Heart rate variability and impulsivity were assessed during each acute tryptophan depletion session and during a baseline session. Suicidal ideation during past depression was used as an index for individual differences in impulse control. Results: High-dose acute tryptophan depletion led to a larger increase in depressive symptoms than did low-dose acute tryptophan depletion. High-dose acute tryptophan depletion decreased heart rate variability and increased impulsivity and anxiety, but only in patients with a history of suicidal ideation. Symptom effects of high-dose acute tryptophan depletion correlated with low heart rate variability at baseline. Conclusions: Depressed patients who have problems with controlling impulsivity might be more at risk for developing cardiovascular disease, possibly related to increased vulnerability to impaired 5-hydroxytryptamine function.
