Women, mental health and health-related quality of life in coronary patients.

OBJECTIVE: To establish clusters of Health-Related Quality of Life (HRQL) in a population of patients hospitalised for suspected Coronary Heart Disease (CHD), and to examine the relationship between mental health and other sociodemographic and clinical variables associated with worse HRQL. METHODS: We conducted a cross-sectional study of 185 patients admitted to the Cardiology Service. We used the General Health Questionnaire (GHQ-28) to assess the mental status, and the SF-36 to assess Health Related Quality Life (HRQL). Using the patients' scores obtained from the SF-36, we performed a cluster analysis and used a logistic model for the analysis of the variables associated with HRQL clusters. RESULTS: We identified two HRQL clusters: good quality of life, for which the patients scored highest in all the dimensions of SF-36, and worse quality of life, for which patients had lower scores in all dimensions. The variables associated with the worse quality of life group were: female gender, previous history of Coronary Heart Disease (CHD), and poor mental health. CONCLUSIONS: Being female, having poor mental health and a previous history of CHD were identified as representing a vulnerable group with worse HRQL.

The role of age in the development of Schneiderian symptoms in patients with a first psychotic episode.

OBJECTIVE: The likelihood of developing psychotic symptoms greatly increases after puberty. In acute psychotic disorders, first rank symptoms (FRS) are prevalent and considered useful for the diagnostic process. The aim of this study was to test for a linear association between age and the probability of occurrence of FRS in patients with a first psychotic episode (FPE). METHOD: A total of 112 patients, consecutively admitted with an FPE, were included at baseline and evaluated yearly over a 3-year period using SCID-I and a checklist of 11 items of FRS. RESULTS: FRS were documented for 65.2% patients at baseline. There was a dose-response relationship in the association between age and FRS. There was no interaction with sex or with final diagnostic category. CONCLUSION: Variation in the expression of the core positive symptoms of psychosis is subject to the influence of underlying age-dependent maturational processes both in terms of occurrence and level of severity.

Age-dependence of Schneiderian psychotic symptoms in bipolar patients.

Psychotic symptoms frequently occur in bipolar disorder, especially in younger patients. However, whether the association with younger age also extends to psychotic symptoms that have traditionally been associated with schizophrenia, such as Schneiderian first-rank symptoms (FRSs), is unclear. This study examined FRSs in bipolar I patients and their relationship to age and gender. The sample comprised 103 consecutive inpatients who met DSM IV criteria for bipolar disorder, manic or mixed. FRSs were rated with the Scale for the Assessment of Positive Symptoms (SAPS). Interaction between FRSs and gender and FRSs and age was assessed using logistic regression. A high rate of FRSs in manic and mixed patients was found with a higher frequency in men (31%) than in women (14%; P=0.038). A monotonic increase in the association between FRSs and younger age was apparent (odds ratios (OR) over five levels: 1.42; 1.00-2.01). These results confirm previous findings that FRSs are not specific to schizophrenia and suggest in addition that a dimension of nuclear psychotic experiences of developmental origin extends across categorically defined psychotic disorders.

Principal components of mania.

OBJECTIVE: An alternative to the categorical classification of psychiatric diseases is the dimensional study of the signs and symptoms of psychiatric syndromes. To date, there have been few reports about the dimensions of mania, and the existence of a depressive dimension in mania remains controversial. The aim of this study was to investigate the dimensions of manic disorder by using classical scales to study the signs and symptoms of affective disorders. METHODS: One-hundred and three consecutively admitted inpatients who met DSM IV criteria for bipolar disorder, manic or mixed were rated with the Young Mania Rating Scale (YMRS) and the Hamilton Depression Rating Scale (HDRS-21). A principal components factor analysis of the HDRS-21 and the YMRS was carried out. RESULTS: Factor analysis showed five independent and clinically interpretable factors corresponding to depression, dysphoria, hedonism, psychosis and activation. The distribution of factor scores on the depressive factor was bimodal, whereas it was unimodal on the dysphoric, hedonism and activation factors. Finally, the psychosis factor was not normally distributed. LIMITATIONS: Patients of the sample were all medicated inpatients. CONCLUSIONS: Mania seems to be composed of three core dimensions, i.e. hedonism, dysphoria and activation, and is frequently accompanied by a psychotic and a depressive factor. The existence of a depressive factor suggests that it is essential to evaluate depression during mania, and the distribution of the depressive factor supports the existence of two different states in mania.

Suicide attempts in bipolar patients.

BACKGROUND: Between 25% to 50% of patients with bipolar disorder make suicide attempts during their lives, but there are some controversies about factors related to suicide attempts in this group of patients. The aim of this study is to investigate the association between suicide attempts and the predictive factors previously described in the literature. METHOD: The sample included all 169 patients with DSM-III-R bipolar I disorder identified in a delimited area (northern Spain). Sociodemographic, clinical, and family history variables measured by Research Diagnostic Criteria-Family History were analyzed. Significant variables were introduced in a logistic regression analysis to control for the effects of other variables. RESULTS: There were 56 patients (33%) who had one or more suicide attempts. Early age at onset, history of hospital admission during depressive episodes, drug abuse, and family history were significantly associated with suicide in the univariate analyses (p < .05). A much higher proportion of patients with onset at or before 25 years of age than patients with onset after 25 years of age attempted suicide (23% vs. 10%). The age at onset was no longer significant after controlling for the other 3 variables included in the logistic regression analysis. CONCLUSION: Suicide attempts are highly prevalent in bipolar patients and are related to drug abuse, family history of affective disorders, and severe depressive episodes. This study suggests that the risk of suicide in patients with an early age at onset could reflect other variables such as drug abuse, a history of hospital admissions for depression, or family history.

Tardive dyskinesia associated with higher mortality in psychiatric patients: results of a meta-analysis of seven independent studies.

This article reports a meta-analysis of seven independent studies on the association of tardive dyskinesia with all-cause mortality in psychiatric patients. Most of the studies included provide either small sample sizes or follow-up periods too short to reach a substantive conclusion on their own. In the meta-analysis, the overall odds ratio (OR) was significant when calculated either by the fixed-effects model (OR = 1.4, 95% confidence interval [CI] = 1.2-1.7, p < 0.005) or the random-effects model (OR = 1.4, 95% CI = 1.1-1.8, p < 0.005). There was no overall heterogeneity (Q test = 8.1, df = 7,p = 0.32). The overall estimate changed within study designs (OR = 1.4,p = 0.002 in three prospective controlled studies; OR = 2.2, p = 0.02 in two prospective uncontrolled studies; and OR = 0.9, p = 0.80 in two retrospective controlled studies). It was modified upward when the two most influential studies (one prospective and one retrospective) were removed from the overview (OR = 2.2, 95% CI = 1.4-3.5,p = 0.001; Q test = 0.81, df = 4,p = 0.94). The conclusion of the meta-analysis was that tardive dyskinesia must be considered a weak risk factor in terms of mortality. It remains to be elucidated whether it is a risk factor on its own or just a surrogate for any unknown organic liability.

[Effectiveness of medical advice for reducing excessive alcohol consumption. Meta-analysis of Spanish studies in primary care].

INTRODUCTION: Former systematic reviews have backed the efficacy of medical counselling, a form of brief intervention, on the treatment of excessive drinkers detected in primary care settings. Nevertheless, these results cannot be applied without criticism to Mediterranean populations which, so far, have not been represented in the aforementioned studies. The aim of the present study was to update the results on the efficacy of brief interventions in primary care by pooling Spanish studies. METHODS: Studies were searched for by using appropriate databases and also by consulting to experts in the field to retrieve grey literature. Pooled estimations of effect sizes were calculated for two outcomes, the reduction in the amount of alcohol consumption and the decrease in the number of excessive drinkers. RESULTS: Two over the 5 retrieved studies were not included in a former review. The effect size regarding the decrease of alcohol consumption was medium (d = 0.46; 95% CI, 0.29 to 0.63; p < 0.0005; the intervention group outperformed the control by a 22%) and small for the decrease in the frequency of excessive drinkers (OR = 1.55; 95% CI, 1.06 to 2.26; p = 0.02; the intervention group outperformed the control by a 11%). The analysis by complimented protocols at the end of the study showed an effect size 1.5 times larger than the analysis performed on intention-to-treat basis. CONCLUSIONS: The results of this meta-analysis support the efficacy of brief intervention for excessive drinkers in primary care settings in Spain.

[Application in medical students of the Zielke questionnaire for changes after group processes].

It has been studied with the Zielken questionnaire the modification of second year medical students mental health symptomatology after two different group activities. The results showed that subjects who participate in any groups improved significantly when compared those of the sensitization treatment groups with those with control groups results indicates that sensitization groups subjects grew better than controls for the perception of professional difficulties. Internal locus of control for mood disturbances diminished more in control groups.

[The clomipramine test and subtypes of depression].

OBJECTIVE: Neuroendocrine challenge paradigms have been used to assess serotonergic system in depression but limitations in the specificity of many of these tests have been noted. In this study, the neuroendocrine responses to acute intravenous administration of the serotonin (5-HT) reuptake inhibitor clomipramine were assessed in patients with Major Depression with Melancholia (DMM) and matched subjects with Major Depression (DM) (without Melancholia) and Dysthimic disorder (TD). METHOD: 10 patients who met DSM III-R criteria of DMM, 10 patients with DM and 10 with DD matched for age and sex received 12.5 mg of intravenously administered clomipramine. Prl, Cortisol and GH were measured during the next 135 minutes. RESULTS: The DMM patients had significant blunting prolactin responses to clomipramine compared with the other patients. CONCLUSIONS: These data support the hypothesis that DMM patients have abnormal neuroendocrine responses to the intravenous administration of the 5-HT reuptake inhibitor clomipramine and that they are different from the DM and TD patients.

[Serotonergic function in endogeneity of depression].

OBJECTIVE: This study employed an alternative method for assessing serotonergic function in depression. The neuroendocrine responses to acute intravenous administration of the serotonin (5-HT) reuptake inhibitor clomipramine were assessed in patients with Major Depression with Melancholia (DMM) and matched subjects with Major Depression (DM) (without Melancholia) and Dysthimic disorder (TD). METHOD: 10 patients who met DSM III-R criteria of DMM, 10 patients with DM and 10 with DD matched for age and sex received 12.5 mg of intravenously administered clomipramine. Prl, Cortisol and GH were measured during the next 135 minutes. We divided the samples using the Newcastle Scale. RESULTS: The DMM patients had significant blunting prolactin responses to clomipramine compared with the other patients. Most of the major depression patients without melancholia were neurotic depressions according to the Newcastle Scale. There was a negative correlation between endogeneity and prolactin response. CONCLUSIONS: These data support the hypothesis that DMM patients have abnormal neuroendocrine responses to the intravenous administration of the 5-HT reuptake inhibitor clomipramine, and that there is an association between endogeneity and prolactin response.
