Borrelia burgdorferi (Bb) infection can affect the central nervous system and possibly lead to psychiatric disorders. We compared clinical and demographic variables in Bb seropositive and seronegative psychiatric patients and healthy controls.

Nine hundred and twenty-six consecutive psychiatric patients were screened for antibodies to Bb and compared with 884 simultaneously recruited healthy subjects.

Contrary to healthy controls, seropositive psychiatric patients were significantly younger than seronegative ones. None of the studied psychiatric diagnostic categories exhibited stronger association with seropositivity. There were no differences between seropositive and seronegative psychiatric patients in hospitalization length, proportion of previously hospitalized patients and proportion of subjects with family history of psychiatric disorders.

These findings elaborate on potential association between Bb infection and psychiatric morbidity, but fail to identify any specific clinical ‘signature’ of Bb infection.

The 28-item version of the General Health Questionnaire (GHQ-28) developed by Goldberg and Hillier in 1979 is constructed on the basis of a principal components analysis of the GHQ-60. When used on a Spanish population, a translation of the GHQ-28 developed for an English population may lead to worse predictive values.

We used our Spanish sample to replicate the entire process of construction of the GHQ-28 administered in a primary-care setting.

Two shorter versions were proposed: one with six scales and 30 items, and the other with four scales and 28 items.

The resulting GHQ-28 was a successful adaptation for use on the Spanish sample. When compared with the original version, only 21 items were the same. Moreover, contrary to the English version, which groups sleep problems and anxiety in the same scale, a scale with items related exclusively to ‘Sleep disturbances’ was found.

We studied the relationship between depressive symptoms and quality of life (QOL) as well as functional status in primary brain tumor patients at recurrent measurements. Differences in QOL between depressive and non-depressive samples by gender were controlled for tumor characteristics and patients' psychosocial factors.

The data consisted of 77 patients with a primary brain tumor, 30 males and 47 females. Depression of the patients was assessed by Beck Depression Inventory (BDI) and Crown-Crisp Experiential Index (CCEI), functional status by Karnofsky Performance scale (KPS) and QOL by Sintonen's 15D before tumor operation as well as at 3 months and at 1 year from surgical operation of the tumor.

The level of QOL in females was lower compared to that of males. Depression was the main predictor for worse QOL in the patients at all measurements. Depressive patients with a benign brain tumor had significantly worse QOL versus non-depressive ones.

Decreased QOL was strongly related to depression, especially among patients with a benign brain tumor. Further studies are needed to find whether sufficient depression therapy improves the QOL of patients.

All suicide attempts cannot predict suicide, therefore we examined those characteristics of suicide attempt which could most accurately predict completed suicide.

Subjects were all individuals registered as committed suicides (N = 16,522) or attempted suicides (N = 15,057) in the register of suicides of the Republic of Slovenia between 1970 and 1996. Log linear analysis of a frequency table was used to uncover relationship between categorical variables.

The model we found fit between variables: mode, number of repetitions and type, then between number of repetitions, type and gender, and between mode, type and gender.

The risk of suicide in those who previously attempted suicide is approximately 773 times higher than the risk of suicide without a previous suicide attempt. Those who attempt suicide by hanging (hanging being in Slovenia the most frequent mode of completed suicide) are at even greater risk to commit suicide.

Our data suggests that clinicians should heighten their awareness that any suicide attempt can in some 20% predict suicide. Someone who has attempted suicide by hanging is at the highest risk of suicide.

Decreased hippocampal volume reported in neuropsychiatric and endocrine disorders is considered a result of putative neuronal damage mediated by corticosteroids. This is the first prospective study of hippocampal volume and function in patients treated with corticosteroids.

14 subjects treated systemically with prednisone or betamethasone for dermatological or rheumatic disorders underwent prospective neurocognitive testing (Auditory Verbal Learning Test—AVLT, Trail Making Test—TMT, Digit Span—DS) and nine of them also repeated magnetic resonance volumetry.

The mean duration of treatment between the first and the second assessment was 73 ± 38 days with mean daily dose of 37 ± 17 mg prednisone and 193 ± 29 days, with mean daily dose of 24 ± 15 mg prednisone between the first and the third assessment. There was a trend towards decreases in total AVLT scores and an improvement in the TMT and DS, but no significant changes in the volumes of the right or the left hippocampi between the assessments. Prednisone dose did not correlate with the hippocampal volume change.

We observed a trend for decline in verbal memory despite improvement in psychomotor speed, attention/working memory and no macroscopic hippocampal volume changes during 36–238 days of treatment with therapeutic doses of corticosteroids.

The objective of our study was to evaluate the psychological consequences of real-world AAS use in athletes abusing such agents, in comparison with a placebo and control group of comparable athletes, while correlating the severity of abuse with the side effects observed. The hypothesis tested by the study was that the use of AAS induces a wide range of psychological side effects whose impact and emergence is dependent upon the severity of the abuse.

The study includes a substantial group of AAS abusing athletes and two more groups demographically similar to the first, one composed of athletes not using any substance and a placebo group. All athletes were stratified according to the severity of AAS abuse. Psychometric instruments were applied to all athletes in specific time intervals, dependent to the AAS abusers' regimens, providing us with a final psychological profile that was to be compared to the pre-study profile. All results were comparable (within and between groups) for statistically significant differences and correlated to the severity of the abuse. Homogeneity of all groups was safeguarded by random doping controls, monitoring of drug levels and analysis of all self obtained drugs by method of liquid chromatography/mass spectrometry. All athletes were provided with a common exercise and dietary regime, so common training and nutritional conditions were achieved.

We studied a cohort of 320 body-building, amateur and recreational athletes, of whom 160 were active users of AAS (group C), 80 users administering placebo drugs (group B) and 80 not abusing any substance (Group A). Group C athletes were stratified according to AAS abuse parameters, thus providing us with three subgroups of “light, medium and heavy abuse”. Athletes of groups A and B were included in a “no abuse” subgroup. The psychometric instruments used were the Symptoms Check List-90 (SCL-90) and the Hostility and Direction of Hostility Questionnaire (HDHQ). The psychometric evaluations took place within a time interval of 13 months. Statistical analysis was performed by using the Mann–Whitney/Wilcoxon two-sample non-parametric test (Kruskal–Wallis test for two groups) for data that were not normally distributed and Linear regression analysis was used to ascertain the correlation between severity of use and escalation of side effects.

The study showed a statistically significant increase in all psychometric subscales recorded in group C, and no statistically significant difference in group C and A. There was a significant increase in the scorings of group C for all subscales of SCL-90 and HDHQ. Correlation of abuse severity and side effects showed that there was a statistical significant increase in Δ values of all SCL-90 and HDHQ subscales that escalated from light abuse to medium and heavy abuse/consumption patterns.

The results of the study suggest that the wide range of psychiatric side effects induced by the use of AAS is correlated to the severity of abuse and the force of these side effects intensifies as the abuse escalates.

The aim of this study is to examine the utilization of psychiatric services for inpatients with psychosis over a period of five years after first admission, and to identify factors that contribute to intensive service use in terms of cumulative length of in-patient treatment and readmission rate.

A cohort of 424 patients with psychotic disorders (out of a sample of 2565 first-admitted patients from a catchment area in Switzerland) was examined by means of register data.

Patients admitted for psychosis spent the longest time in hospital compared to other diagnoses, but there was considerable within-sample variation, and most patients (60.4%) had only one in-patient episode. Of the total time accumulated in this sample, 50.5% was ‘consumed’ by 10.7% of patients. Regarding the overlap between ‘heavy use’ and ‘frequent use’ (those 10% of the sample with the longest/ most frequent hospitalizations), only 39.5% of the ‘frequent users’ were also ‘heavy users’ (vice versa: 38.6%). ‘Clinical’ measures were the main predictors of the overall time spent as an in-patient (schizophrenia diagnosis, therapeutic measures, clinical improvement). Concerning ‘heavy use’, homelessness was yet another important risk factor. Sociodemographic variables (age, level of education, living alone) particularly influenced the number of hospitalizations. A younger age at first admission was predictive of ‘heavy’ and ‘frequent’ use.

Clinical and sociodemographic factors explain differences in in-patient service consumption among patients with psychosis. Efforts to devise effective interventions have to take both into account, but different measures are needed to address ‘heavy’ and ‘frequent’ use.

The aim of the present study was to examine whether psychiatric morbidity can influence the type of illness behaviour of neurological inpatients.

For this purpose, we compared neurological inpatients with and without psychiatric disorders (DSM-IIIR criteria) for the seven scales of Illness Behaviour Questionnaire (IBQ) and searched for possible differences between the two patient subgroups.

Of the 105 neurological inpatients who participated in the study, 54 (51.4%) were diagnosed as having some type of psychiatric disorder. These patients scored significantly higher than patients without psychiatric morbidity in the scale of Irritability. A suggestive trend for higher scores in the scales of Hypochondriasis, Disease Conviction, and Affective Disturbance, and significantly lower score in the scale of Denial, in patients with psychiatric morbidity, were also found.

The present study has shown that neurological inpatients with psychiatric morbidity tend to develop more intense illness behaviour than those without. The effect of psychiatric morbidity on certain components of illness behaviour in neurological patients can be taken into account when therapeutic strategies are planned.

Impulsivity, a core feature of bipolar disorder (BD), is a multifaceted concept encompassing failure of response inhibition and poor decision-making. Abnormalities in these two cognitive domains have been reported in BD patients but their relationship with impulsivity has not been explored.

Twenty-five remitted patients with BD completed the Barratt Impulsiveness Scale (BIS) and performed the Hayling Sentence Completion Task (HSCT) and a computerized version of the Iowa Gambling task. The HSCT total errors scaled score was used as a measure of response inhibition while the gabling task score, which reflects participants' ability to make advantageous choices, was used a measure of decision making.

Higher scores on the BIS attentional and non-planning subscales were respectively associated with more errors in the HSCT and less advantageous choices in the gambling task.

All patients were medicated. Healthy participants were not included.

Viewed in the context of recent relevant studies our findings suggest that impulsivity, response inhibition and decision-making in BD may represent behavioural manifestations of the same underlying biological mechanism possibly linked to ventral prefrontal cortical function.
