RESUMO
Available data shows associations between chronotype, circadian rhythms, sleep quality and fibromyalgia (FM) presentation. However, no studies have explored links between the chronobiological variables and effectiveness of pharmacotherapy. We aimed to assess the chronotypes, circadian rhythms, sleep-wake cycle and sleep quality in FM and their links to treatment response to serotonin and noradrenalin reuptake inhibitors (SNRI). 60 FM patients: 30 responsive to SNRI (FM T[+]), 30 non-responsive to SNRI (FM T[-]) and 30 healthy controls participated. Subjects were assessed by physician and with questionnaire tools: Composite Scale of Morningness, Biological Rhythms Interview of Assessment in Neuropsychiatry, Sleep-Wake Pattern Assessment Questionnaire, Pittsburgh Sleep Quality Index and Fibromyalgia Impact Questionnaire. ANOVA analysis and simple logistic regressions were used to examine the relationships between chronological variables and response to SNRI. FM T[-] vs. FM T[+] presented lower morning affect (11.50[95%CI 9.96-13.04] vs. 14.00[95%CI 12.42-15.57];p=0.04), anytime wakeability (2.27[95%CI 1.4-3.13] vs. 4.03[95%CI 2.99-5.08];p=0.013) worse overall (11.40[95%CI 9.92-12.88] vs. 7.97[95%CI 6.75-9.19];p=0.002) and subjective (1.70[95%CI 1.30-2.01] vs. 1.17[95%CI 0.94-1.39];p=0.008) sleep quality, higher circadian rhythm disruptions (55.47[95%CI 52.32-58.62] vs. 44.97[95%CI 41.31-48.62];p<0.001), sleep disturbances (1.63[95%CI 1.38-1.68] vs. 1.30[95%CI 1.1-1.5];p=0.04), sleeping-medication use (1.80[95%CI 1.27-2.32] vs. 0.70[95%CI 0.28-1.12];p=0.003). Levels of morningness (AIC=82.91,OR=0.93,p=0.05), morning affect (AIC=81.901,OR=0.86,p=0.03) diurnal dysrhythmia (AIC=69.566,OR=1.14,p<0.001), anytime wakeability (AIC=80.307,OR=0.76,p=0.015), overall sleep quality (AIC=74.665, OR=1.31,p=0.002) subjective sleep quality (AIC=79.353, OR=2.832,p=0.01) and disturbances (AIC=82.669,OR=2.54,p=0.043), sleep medication use (AIC=77.017, OR=1.9,p=0.003) and daytime disfunction (AIC=82.908, OR=1.971,p=0.049) were predictors of non-response to SNRI. Chronobiological variables vary between FM T[+] and FM T[-] and are predictors of non-response to SNRI.
RESUMO
Mood disorders are highly prevalent and heterogenous mental illnesses with devastating rates of mortality and treatment resistance. The molecular basis of those conditions involves complex interplay between genetic and environmental factors. Currently, there are no objective procedures for diagnosis, prognosis and personalization of patients' treatment. There is an urgent need to search for novel molecular targets for biomarkers in mood disorders. Cellular prion protein (PrPc) is infamous for its potential to convert its insoluble form, leading to neurodegeneration in Creutzfeldt-Jacob disease. Meanwhile, in its physiological state, PrPc presents neuroprotective features and regulates neurotransmission and synaptic plasticity. The aim of this study is to integrate the available knowledge about molecular mechanisms underlying the impact of PrPc on the pathophysiology of mood disorders. Our review indicates an important role of this protein in regulation of cognitive functions, emotions, sleep and biological rhythms, and its deficiency results in depressive-like behavior and cognitive impairment. PrPc plays a neuroprotective role against excitotoxicity, oxidative stress and inflammation, the main pathophysiological events in the course of mood disorders. Research indicates that PrPc may be a promising biomarker of cognitive decline. There is an urgent need of human studies to elucidate its potential utility in clinical practice.

This article discusses a new method for monitoring drug concentrations in blood samples from patients with mood disorders. The method uses solid-phase microextraction to extract analytes directly from blood samples. It has been adapted to identify the most commonly used drugs in mood disorders, including amitriptyline, citalopram, fluoxetine, paroxetine, sertraline, trazodone, duloxetine, venlafaxine, lamotrigine, quetiapine, olanzapine, and mirtazapine. The analysis is carried out using high-performance liquid chromatography coupled with mass spectroscopy. The proposed DI-SPME/LC-MS method allows for a simple and quick screening analysis while minimizing the volume of the tested sample and solvent, in line with the principles of green analytical chemistry. The method was used to analyze 38 blood samples taken from patients with mood disorders, and drug concentrations were determined and compared with therapeutic and toxic dose ranges. This allowed for better control of the course of treatment.

AIMS: The aim of the study was to check the prevalence of unipolarity (depression), bipolarity, as well as the quality of sleep and temperament traits in patients with type 1 diabetes (T1DM) who are provided with optimal conditions of diabetes care and to identify possible risk factors connected with affective traits. MATERIALS AND METHODS: Out of the 107 T1DM patients, 78 (54 females, 24 males) were included for the analysis (HbA1c [%] 7.11 ± 1.0, BMI [kg/m2 ] 25.3 ± 5.6; Years of disease duration [N] 13.7 ± 8.3). The patients filled in a set of questionnaires during their regular visit to the outpatient clinic. Three patients from the whole group were on intensive insulin therapy with Multiple Daily Injections (MDI) and Self-Monitoring of Blood Glucose (SMBG), all the rest were on various types of personal insulin pumps (years on insulin pump [N] 9.1 ± 4.5). All the patients were on regular diabetologist care, with regular visits in a Centre for Advanced Technologies in Diabetes (at least every 6 months). RESULTS: In QIDS-S (full explanation and abbreviation 26 patients (33.8%) were screened positive for depression, in PHQ (full explanation and ab 57.7% of the patients (45 patients) had symptoms of depression (age was negatively correlated with PHQ score [r = -0.26; p = 0.023]). In CES-D 16 (20%) of the patients assessed their present affect as depressed. None of the analysed clinical variables correlated with depression scores. In the Mood Disorder Questionnaire (MDQ), 16 patients reported having symptoms of bipolarity (20.5% vs. 79.5%). Hypomania Checklist (HCL) analysis indicated 10 patients with bipolar traits (>14) (14.9% vs. 85.1%). None of the analysed clinical variables correlated with HCL results. 11.5% of patients were indicated to be of morning type. Morningness was more often seen in younger patients (r = 0.39; p = 0.001). As many as 46.6% declared that they had poor sleep quality. The temperament traits analysis correlated with clinical parameters: Cyclothymic temperament trait was negatively correlated with age (r = -0.30; p = 0.007) and positively with HbA1c level (r = 0.30; p = 0.025). Hyperthymic temperament was positively correlated with (BMI r = 0.28; p = 0.016). Quality of sleep was highly correlated with depressive symptoms CESD (r = 0.61, p = 0.001), PHQ Score (r = 0.62; p = 0.001), QISD (r = 0.68; p = 0.001) and bipolarity MDQ (p = 0.50, p = 0.001) and HCL (r = 0.42, p = 0.001). In addition, QIDS was shown to be correlated with the following features of temperament: depressive factor (r = 0.41; p = 0.001), irritable factor (r = 0.53; p = 0.001), cyclothymic factor (r = 0.59; p = 0.001), anxious factor (r = 0.58, p = 0.001). CONCLUSIONS: The prevalence of affective disorders and poor sleep quality in the examined T1DM patients was much higher than in the general population. Even if the patients have in general good glycaemic control, their mental health condition should not be neglected. Well organised cooperation between patients, diabetologists, psychiatrists and psychotherapists is needed (Clinical Trials Identifier: NCT04616391).

BACKGROUND: Studies show significant co-occurrence of bipolar disorder and prostate cancer, as well as the presence of shared genes associated with both diseases. Our aim was to evaluate whether prostate cancer patients present bipolar spectrum symptoms and to establish their possible associations with stress related symptoms during diagnosis and the course of the cancer therapy. METHODS: 200 participants were enrolled to this study: 100 prostate cancer patients and 100 healthy males. Bipolar spectrum symptoms were measured with the use of Mood Disorder Questionnaire and Hypomania Checklist-32 (HCL-32). Stress related symptoms were rated with The Impact of Events Scale-Revised (IES-R), Perceived Stress Scale-10 (PSS-10) and Generalised Self-Efficacy Scale (GSES). RESULTS: In comparison to healthy controls group, prostate cancer patients have shown higher HCL-32 scores. Mood Disorder Questionnaire measures were associated with more severe stress related to prostate cancer diagnosis and treatment reflected by higher scores of IES-R and its subscales (Avoidance, Intrusions and Hyperarousal). Mood Disorder Questionnaire, HCL-32, PSS-10, IES-R and GSES measures were not associated with clinical characteristics of prostate cancer severity. LIMITATIONS: Cross-sectional study model precluded identification of causal relationship among variables. Bipolar spectrum symptoms and stress related measures were based on auto-questionnaires. CONCLUSIONS: To our best knowledge, this is the first study evaluating bipolar spectrum symptoms in prostate cancer patients. We have shown that this clinical group presents increased bipolarity traits compared to healthy individuals. Moreover, bipolar spectrum symptoms were associated with more severe stress related to the prostate cancer diagnosis and its treatment, reflected in avoidance, hyperarousal, and intrusions.

In the assessment of adult attention-deficit hyperactivity disorder (ADHD) symptoms, the diagnostic value of neuropsychological testing is limited. Partly, this is due to the rather low ecological validity of traditional neuropsychological tests, which usually present abstract stimuli on a computer screen. A potential remedy for this shortcoming might be the use of virtual reality (VR), which enables a more realistic and complex, yet still standardized test environment. The present study investigates a new VR-based multimodal assessment tool for adult ADHD, the virtual seminar room (VSR). Twenty-five unmedicated ADHD patients, 25 medicated ADHD patients, and 25 healthy controls underwent a virtual continuous performance task (CPT) in the VSR with concurrent visual, auditive, and audiovisual distractions. Simultaneously, head movements (actigraphy), gaze behaviour (eye tracking), subjective experience, electroencephalography (EEG), and functional near-infrared spectroscopy (fNIRS) were recorded. Significant differences between unmedicated patients with ADHD and healthy controls were found in CPT performance, head actigraphy, distractor gaze behaviour, and subjective experience. Moreover, CPT performance parameters demonstrated potential utility for assessing medication effects within the ADHD population. No group differences were found in the Theta-Beta-Ratio (EEG) or dorsolateral-prefrontal oxy-haemoglobin (fNIRS). Overall, the results are very promising regarding the potential of the VSR as an assessment tool for adult ADHD. In particular, the combined assessment of CPT, actigraphy, and eye tracking parameters appears to be a valid approach to more accurately capture the heterogeneous symptom presentation of the disorder.

The main objective of this study was to develop a test for the fast and noninvasive prediagnosis of mood disorders based on the noninvasive analysis of hair samples. The database included 75 control subjects (who were not diagnosed with depression) and 40 patients diagnosed with mood disorders such as depression or bipolar disorder. Both women and men, aged 18-65 years, participated in the research. After taking the hair samples, they were washed (methanol-water-methanol by shaking in a centrifuge for two min) and air-dried in a fume hood. Each hair collection was analyzed using Fourier transform infrared spectroscopy attenuated total reflection (ATR-FTIR) spectroscopy. Subsequently, the results obtained were analyzed based on chemometric methods: hierarchical cluster analysis (HCA) and principal component analysis (PCA). As a results of the research conducted, potential differences were noticed. There was a visible change in the spectra intensity at around 2800-3100 cm-1 and smaller differences around 1460 cm-1; the bands can be assigned to protein vibrations. However, these are preliminary studies that provide a good basis for the development of a test for the initial diagnosis of mood disorders.

The diagnosis of affective disorders has been the subject of constant research by clinicians from all over the world for many years. Making an appropriate diagnosis among patients suffering from mood disorders is sometimes problematic due to the personality-changing nature of patients and the similarity in the clinical picture of episodes in affective disorders. For this reason, there is a need to develop rapid and effective methods of determining biological markers that differentiate these diseases. The research was carried out with blood taken from 15 patients and 15 volunteers. The analysis of biological material for trace concentrations of zinc and copper was carried out with the use of ultrasensitive triple-quadrupole inductively coupled plasma mass spectrometry (TQ ICP-MS). The obtained results prove that the concentration of copper in the test group was lower than in the control group. For the zinc concentrations, the inverse relationship was observed. The group of patients was characterized by a higher concentration of this element than the group of healthy volunteers. Summarizing the obtained results and comparing them with the results of studies by other authors, it was found that zinc and copper may be potential biomarkers of affective disorders and pandemic syndrome.

Background and Objectives: In the general population, sleep disorders are associated with lower urinary tract symptoms (LUTS) including urinary incontinence (UI). This connection has not been explored fully in specific patient groups. Thus, we investigated the association between sleep quality and LUTS for patients with depression. Materials and Methods: This study was prospective and cross-sectional. We analyzed questionnaire data on depression, sleep quality, LUTS, and UI from depressed patients treated in our department of adult psychiatry. We used the Hamilton Rating Scale for Depression, the Holland Sleep Disorders Questionnaire, the International Prostate Symptom Score, and the International Consultation on Incontinence Questionnaire-Short Form. Results: In total, 102 patients treated for depression were enrolled. We found a statistically significant correlation between depression severity and sleep quality. A significant correlation was also investigated for sleep quality and LUTS severity. The group of depressed patients with moderate or severe LUTS had greater sleep problems compared with patients who had mild urinary tract symptoms or no symptoms. With regression analysis, we further demonstrated that the relationships between LUTS and sleep quality as well as UI and sleep quality in depressed patients are independent from age and sex. Conclusions: In the cohort of patients treated for depression, sleep quality correlated with LUTS including UI. We suggest that the negative effect of LUTS and UI on sleep quality that we observed should lead to the re-evaluation of current recommendations for diagnosis and treatment of sleep problems among patients with depression.

Psychiatric disorders are more common in patients with epilepsy than in the general population. The aims of the study were to assess the frequency and type of psychotropic drug usage in patients with epilepsy, to assess the risk factors for their use, and to assess their proconvulsive potential and the risk of interactions with antiepileptic drugs. This 20-month prospective study included patients treated at the university hospital outpatient clinic. Psychotropic drugs have been classified according to the Anatomical Therapeutic Chemical Classification System. Of the 621 patients (with a mean age of 35.4years), 60% were women, and 37.5% were in remission; 54.8% of the patients used antiepileptic drug monotherapy. The most commonly used antiepileptic drugs were valproate, levetiracetam, lamotrigine, and carbamazepine. Eighty-nine (14.3%) patients received psychiatric comedication. Sertraline, perazine, and hydroxyzine were the predominantly used psychotropic drugs. Independent variables associated with psychotropic drug usage in the logistic regression model included age, active epilepsy, combined focal and generalized epilepsy type, use of somatic comedication, and phenobarbital. Over one-third of the patients simultaneously received antiepileptic drugs and psychotropic drugs, between which clinically significant interactions may occur, 10% of patients used psychotropic drugs to lower the seizure threshold. The results of the study indicate the need for closer cooperation between doctors of various specialties when caring for patients with epilepsy.

Despite many clinical trials assessing the role of zinc in major depressive disorder (MDD), the conclusions still remain ambiguous. The aim of the present clinical study was to determine and comparison the zinc concentration in the blood of MDD patients (active stage or remission) and healthy volunteers (controls), as well as to discuss its potential clinical usefulness as a biomarker of the disease. In this study 69 patients with current depressive episode, 45 patients in remission and 50 controls were enrolled. The zinc concentration was measured by electrothermal atomic absorption spectrometry (ET AAS). The obtained results revealed, that the zinc concentration in depressed phase were statistically lower than in the healthy volunteers [0.89 vs. 1.06 mg/L, respectively], while the zinc level in patients achieve remission was not significantly different from the controls [1.07 vs. 1.06 mg/L, respectively]. Additionally, among the patients achieve remission a significant differences in zinc concentration between group with and without presence of drug-resistance in the previous episode of depression were observed. Also, patients in remission demonstrated correlation between zinc level and the average number of depressive episodes in the last year. Serum zinc concentration was not dependent on atypical features of depression, presence of psychotic symptoms or melancholic syndrome, age, age of onset or duration of disease, number of episodes in the life time, duration of the episode/remission and severity of depression measured by the Hamilton Rating Scale for Depression (HDRS), and the Montgomery-Asberg Depression Rating Scale (MADRS). Concluding, our findings confirm the correlation between zinc deficit present in the depressive episode, and are consistent with the majority of previous studies. These results may also indicate that serum zinc concentration might be considered as a potential biological marker of MDD.

BACKGROUND: The aim of the study was to investigate the total dyadic adjustment (including satisfaction, cohesion, consensus and affectional expression) among spouses of bipolar patients with I and II subtypes. SUBJECTS AND METHODS: 82 subjects (46 women/ 36men) were enrolled in the study - 50 spouses of bipolar I (BD I) patients and 32 spouses of bipolar II (BD II) patients. We used an interview, the Dyadic Adjustment Scale (DAS), and a questionnaire including questions concerning basic socio-demographic data, the duration of marriage, as well as information about the patient's illness. RESULTS: The results indicate that BD I is likely to be more disruptive for life-partners and is associated with a lower dyadic adjustment (assessed by the healthy spouse) than BD type II (p≤0.05). There are differences in DAS scales when specific episodes are compared with each other as well (p≤0.01). Also patients' illicit substance use and co-morbidity were significant factors (p≤0.01). CONCLUSIONS: We would like to emphasize that bipolar disorder affects marriage (even the healthy spouse) and that its different subtypes (especially type I) as well as additional factors may be associated with significant deterioration of a relationship.

BACKGROUND/AIMS: The Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) is a novel tool allowing for a complex assessment of biological rhythms. We compared patients with bipolar disorder (BD) and healthy control subjects (HC) using the Polish version of the BRIAN scale. METHOD: Fifty-four remitted BD patients (17 males and 37 females aged 52 ± 13 years) and 54 healthy control subjects (25 males and 29 females aged 42 ± 14 years) were studied. In addition to the BRIAN scale, the Composite Scale of Morningness (CSM) and the Sleep-Wake Pattern Assessment Questionnaire (SWPAQ) were employed. RESULTS: The Polish version of the BRIAN scale displayed high feasibility and consistency, showing that the patients had greater biological rhythm disturbances than the controls. After regression analysis, significant differences were obtained for the BRIAN subscales activity and predominant chronotype, and for the SWPAQ items quality of night-time sleep and ability to stay awake. We obtained positive correlations between higher BRIAN scores and morningness and eveningness, but the correlations with vigilance and the ability to stay awake (on the SWPAQ) were negative. CONCLUSIONS: Using the BRIAN scale, we confirmed the greater disturbances of biological rhythm in Polish remitted bipolar patients, compared with healthy controls. The differences between these 2 groups in sleep-awake patterns were also demonstrated by the SWPAQ scores. In contrast to other studies, we were unable to confirm an evening chronotype as a discriminating factor between remitted bipolar patients and healthy subjects. This can be explained by the older age and the use of lithium by a significant proportion of the patients.

BACKGROUND: Lowered antioxidant defense systems and increased oxidative stress are implicated in bipolar disorders (BD). Early and late stages of BD may present different biological features (including the level of oxidative stress) and may therefore require different treatment strategies. The aim of this study was to analyze serum levels of lipid peroxidation [measured as thiobarbituric acid-reactive substances (TBARS), a derivative of malondialdehyde] in BD patients at various stages and phases of the illness and compare their TBARS levels with those of healthy controls. METHOD: A total of 129 patients (58 in the depressive episode, 23 in the manic episode and 48 in remission) diagnosed with type I (n = 69) or type II (n = 60) BD and 50 healthy volunteers (control group) were enrolled in the study. The level of lipid peroxidation was measured in blood serum using a TBARS assay kit. RESULTS: TBARS levels in the acute episode of mania/hypomania and depression (but not in remission) were significantly higher than in healthy controls. With regard to the BD stage, both early- and late-stage BD TBARS levels were significantly increased in patients in the depressive episode. In late-stage BD, the TBARS level in patients in remission remained elevated compared with controls. A multiple regression model confirmed the association between the TBARS level and BD stage or acute BD. CONCLUSION: Our findings indicate that TBARS levels reflect the oxidative stress state which increases both in the acute phase of BD (mania/hypomania and depression) and with BD progression (stage).

BACKGROUND: We hypothesised that men and women who engage in extreme or high-risk sports would score higher on standardised measures of bipolarity and impulsivity compared to age and gender matched controls. METHODS: Four-hundred and eighty extreme or high-risk athletes (255 males and 225 females) and 235 age-matched control persons (107 males and 128 females) were enrolled into the web-based case-control study. The Mood Disorder Questionnaire (MDQ) and Barratt Impulsiveness Scale (BIS-11) were administered to screen for bipolarity and impulsive behaviours, respectively. RESULTS: Results indicated that extreme or high-risk athletes had significantly higher scores of bipolarity and impulsivity, and lower scores on cognitive complexity of the BIS-11, compared to controls. Further, there were positive correlations between the MDQ and BIS-11 scores. CONCLUSION: These results showed greater rates of bipolarity and impulsivity, in the extreme or high-risk athletes, suggesting these measures are sensitive to high-risk behaviours.

BACKGROUND AND PURPOSE: The aim of this study was to evaluate the prevalence of suicidal ideation among Polish patients with epilepsy and to assess the potential determinants of suicidality in this cohort. MATERIAL AND METHODS: The study comprised 301 patients with epilepsy seen in the tertiary epilepsy clinic. Patients' characteristics included demographic variables, epilepsy-related variables, as well as occurrence of comorbidities, ongoing use of any other medications, family history of epilepsy and/or depression. Beck Depression Inventory (BDI) was used to assess depressive symptoms, and question no. 9 of BDI was specifically used to reveal suicidality. RESULTS: Mean age of subjects was 35.5 years. 113 (37.5%) had frequent seizures and 96 patients (31.9%) had remission. BDI score>11 points (suggestive for depression) was found in 127 subjects. Suicidal ideation has been revealed in 30 (10.0%) out of 301 studied patients. Patients with suicidal ideation were older and more commonly reported frequent seizures. Almost all of them (93.3%) had clinically significant depressive symptoms (BDI score>11). Multivariate analysis revealed that severity of depressive symptoms (OR=1.16 per one-point increase in BDI score, 95% CI: 1.10-1.22, p<0.001) and the use of potentially depressogenic medication (OR=3.04, 95% CI: 1.04-8.89, p=0.04) were independent determinants of suicidality among studied patients. CONCLUSIONS: Suicidal ideations were revealed by about 10% of studied epileptic patients who visited tertiary center for epilepsy. Independent predictors of suicidality among studied patients included depression itself and the use of potentially depressogenic medication.

BACKGROUND AND PURPOSE: The purpose of the study was to evaluate the frequency of interictal depressive symptoms and different subtypes of depressive disorders according to 10th revision of the International Classification of Diseases (ICD-10) criteria in patients with epilepsy and its association with the type of epilepsy. MATERIAL AND METHODS: 289 outpatients with epilepsy (169 females, 120 males) aged 18-82 years completed Beck Depression Inventory (BDI). Subjects who scored >11 in BDI were further evaluated by the psychiatrist according to the ICD-10 diagnostic criteria. RESULTS: 41.9% (121) of the 289 participants scored >11 in BDI. 104 (85.9%) patients who scored >11 in BDI had comorbid mental disorders according to ICD-10 criteria. The most common were organic mood disorders (F06.3 - 31.4%), depressive episode (F32 - 22.3%) and dysthymia (F34.1 - 9.1%) There were no differences in the prevalence of depression and subtypes of depression in patients with certain epilepsy types. Depression was diagnosed before entering the study in only one third of patients with final diagnosis of depression. CONCLUSIONS: Our results confirm the prevailing view that interictal depression is common in epilepsy patients. Depression remains underrecognized and undertreated in patients with epilepsy.

Effectiveness of currently available antipsychotic medications is far from satisfactory with many patients showing incomplete therapeutic response even after many trials with different antipsychotic drugs. Hence, there is an ongoing interest in searching for pharmacological mechanisms, which could potentiate therapeutic response to antipsychotic drugs and/or reduce its typical side effects. The primary aim of this mini-review is to summarize available evidence supporting the role of serotonin receptors, especially 5-HT7 receptors, in therapeutic effects of a second-generation antipsychotic drug, lurasidone.

Dear Readers We are happy and proud to announce that we managed to achieve intention announced in the last issue: for the first time in PubMed there is a possibility of direct and free access to the full texts published in Polish Psychiatry (Polish and English language versions are available)!!! For the issue 6/2014 they have been downloaded by Medline users already 500 times. Owing to this, papers by Polish scientists-psychiatrists are more readily available to colleagues from around the world interested in them, and Polish Psychiatry actually becomes journal of international scope. We hope that it will result in a marked improvement in the bibliometric indicators (which, however, is unrealistic to expect in the current or next year) in the following years. Spring issue of Polish Psychiatry touches several important problems. We pay attention to the texts on addiction - behavioural (Internet addiction) and alcohol. Two papers by prof. M. Wojnar's team summarize the issues related to the coexistence of alcohol dependence with other psychiatric disorders. The issue of dual diagnosis has already appeared in our magazine (for example [1]). This is an extremely difficult problem, and patients are a real challenge, both therapeutic and diagnostic. They often require a comprehensive approach: pharmacotherapy of comorbid mental illness, psychoeducation, addiction treatment programmes. For these patients the maintenance of abstinence is particularly difficult, especially in a situation of exacerbation of psychopathological symptoms. An important direction is searching for additional pharmacotherapeutic methods which help to reduce the degree of alcohol abuse and the resulting damage. These include: acamprosate, drugs which are opioid receptor antagonists [2], and in the current issue the authors from the University of Cagliari focused on baclofen. (...).

This article presents a summary of available data on the use of quetiapine extended release (QUE-XR). QUE-XR is an example of an atypical antipsychotic drug that can be used in a single dose, thereby simplifying the treatment regimen. From the therapeutic standpoint, this issue is of paramount importance, since approximately 50% of patients have adherence issues. Therefore, availability of the drug which is comfortable in administration can significantly improve treatment outcomes. Due to its antipsychotic, antidepressive, mood stabilizing and anxiolytic efficacy, QUE-XR seems to be a promising drug with potentially broad spectrum of indications (in patients with schizophrenia, bipolar disorder, major depression and some anxiety disorders - both in the acute phase of treatment, and the maintenance treatment). Notably, QUE-XR seems to ameliorate sleep disturbances, and it may also improve patients' quality of life (as suggested by some studies). Due to the simple dosing regimen of QUE-XR, conducting therapy with this drug may contribute to the improvement of compliance. Yet, the primary clinical criterion for selection of the type of formulation of quetiapine should be the individual preferences of the patient, and the knowledge and experience of the treating physician.
