RESUMO

Introduction: Self-immolation is an uncommon way of attempting and committing a suicide, with a fatality rate of 80%. The risk factors in self-immolation victims vary depending on demographic characteristics, socio-economic and cultural factors as well as religious beliefs. Whether the COVID-19 pandemic was a potentially important stressor for self-immolation is still unknown, with insufficient studies examining this issue. Therefore, in this study, we aimed to examine the trend of self-immolation in a 13-year timeline, and the potential association of COVID-19 pandemic with the increase in the incidence and severity of self-immolation injuries in Serbia in 2021. Materials and methods: The study included hospitalized patients due to intentional burns caused by self-immolation in the period from January 1, 2008 to December 31, 2021. Joinpoint regression analysis was used for the analysis of continuous linear trends of self-immolation cases with change points. Results: While a rising trend was observed in the 2008-2013 time segment, followed by a decline in the upcoming 2013-2016 time segment, a significant increase reached its maximum during COVID-19 pandemic (2021), with annual percent change of 37.1% (p = 0.001). A significant increase in the median number of cases per year was observed during 2021 compared to the previous periods (7.5 vs. 2). Frequency of patients with a psychiatric diagnosis vs. those without a psychiatric diagnosis was significantly higher during than before the COVID-19 period (66.7 vs. 36.1%, p = 0.046). Conclusion: In our study, a significant increase in the frequency of suicide attempts by self-immolation during COVID-19 pandemic was noticed. There was also an increased frequency of pre-existing psychiatric illness among patients during the pandemic period. With limited high-quality data available, the study adds to a rising body of evidence for assessment of outcomes of the pandemic on mental health and recognition of stressors for self-immolation.

RESUMO

Introduction: Studies consistently link excessive smartphone use to poor sleep quality, depression, anxiety, and stress. This study specifically aimed to investigate these associations among medical students in Belgrade and Nis (Central Serbia). Materials and methods: The cross-sectional study included a sample of 761 students, who were selected from both the Faculties of Medicine at the University of Belgrade and the University of Nis. Questionnaires, including the International Physical Activity Questionnaire - Short Form (IPAQ-SF), Smartphone Addiction Scale - Short Version (SAS-SV), the Pittsburgh Sleep Quality Index (PSQI), and the Depression, Anxiety, and Stress Scale - 21 items (DASS-21), were completed by the participants. Statistical analysis techniques, such as the Chi-square test, student's t-test, and logistic regression, were employed to examine the relationship between smartphone addiction, physical activity, sleep quality, depression, anxiety, and stress. Results: The findings indicated a prevalence of smartphone addiction among medical students at 21.7%, with rates of 22.9% among males and 21.1% among females. Females exhibited significantly higher scores on the SAS-SV scale compared to males (p = 0.032). Univariate logistic regression analysis revealed significant associations between smartphone addiction and spending over 4 h daily on smartphones (OR = 2.39; p < 0.001), poor sleep quality (OR = 1.65; p = 0,005), as well as elevated levels of stress (OR = 1.75; p = 0.003), anxiety (OR = 2.04; p < 0.001), and depression (OR = 2.29; p < 0.001). Multivariate regression analysis identified spending more than 4 h daily on smartphones (OR = 2.39; p < 0.001) and increased levels of depression (OR = 2.51; p < 0.001) as independent significant factors associated with smartphone addiction. Conclusion: This study sheds light on the prevalence of smartphone addiction among medical students, with spending excessive time on smartphones and higher levels of depression standing out as significant factors. Future research should delve into the underlying mechanisms and causal relationships between smartphone addiction and these psychosocial factors. Understanding these connections will aid in developing effective interventions and strategies to tackle this growing public health concern.

RESUMO

INTRODUCTION: Imaging of retinal structure in psychosis spectrum disorders (PSD) is a novel approach to studying effect of this illness class on CNS structure. Studies of optical coherence tomography (OCT) have revealed significant reductions in regarding: retinal nerve fiber layer (RNFL), macular thickness (MT), ganglion cell-inner plexiform layer (GC-IPL) and macular volume (MV). Sex differences in retinal structure in PSD have not been previously explored. METHODS: This cross-sectional pilot study included 81 participant of age matched patients and controls. There were no differences between genders regarding illness duration and antipsychotic daily dose in the patient group. SD-OCT assessed RNFL, GC-IPL, MT, MV, and optic nerve cup-to-disc (C/D) ratio. In order to assess the main effects of illness, sex, and illness × sex interaction on the retinal parameters, general linear model was performed. RESULTS: Patients demonstrated abnormalities on all OCT indices. Effects of sex were observed for central subfield MT and C/D ratio, which were lower in females. An illness × sex interaction effect was observed for the left MT, indicating greater thinning in female patients. CONCLUSION: Sex differences in OCT findings in PSD appear to be most prominent considering macular parameters. These preliminary data may have important implications for the valid interpretation of OCT findings as potential biomarkers for PSD.

RESUMO

Importance: Precise estimation of the drug metabolism capacity for individual patients is crucial for adequate dose personalization. Objective: To quantify the difference in the antipsychotic and antidepressant exposure among patients with genetically associated CYP2C19 and CYP2D6 poor (PM), intermediate (IM), and normal (NM) metabolizers. Data Sources: PubMed, Clinicaltrialsregister.eu, ClinicalTrials.gov, International Clinical Trials Registry Platform, and CENTRAL databases were screened for studies from January 1, 1990, to June 30, 2020, with no language restrictions. Study Selection: Two independent reviewers performed study screening and assessed the following inclusion criteria: (1) appropriate CYP2C19 or CYP2D6 genotyping was performed, (2) genotype-based classification into CYP2C19 or CYP2D6 NM, IM, and PM categories was possible, and (3) 3 patients per metabolizer category were available. Data Extraction and Synthesis: The Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines were followed for extracting data and quality, validity, and risk of bias assessments. A fixed-effects model was used for pooling the effect sizes of the included studies. Main Outcomes and Measures: Drug exposure was measured as (1) dose-normalized area under the plasma level (time) curve, (2) dose-normalized steady-state plasma level, or (3) reciprocal apparent total drug clearance. The ratio of means (RoM) was calculated by dividing the mean drug exposure for PM, IM, or pooled PM plus IM categories by the mean drug exposure for the NM category. Results: Based on the data derived from 94 unique studies and 8379 unique individuals, the most profound differences were observed in the patients treated with aripiprazole (CYP2D6 PM plus IM vs NM RoM, 1.48; 95% CI, 1.41-1.57; 12 studies; 1038 patients), haloperidol lactate (CYP2D6 PM vs NM RoM, 1.68; 95% CI, 1.40-2.02; 9 studies; 423 patients), risperidone (CYP2D6 PM plus IM vs NM RoM, 1.36; 95% CI, 1.28-1.44; 23 studies; 1492 patients), escitalopram oxalate (CYP2C19 PM vs NM, RoM, 2.63; 95% CI, 2.40-2.89; 4 studies; 1262 patients), and sertraline hydrochloride (CYP2C19 IM vs NM RoM, 1.38; 95% CI, 1.27-1.51; 3 studies; 917 patients). Exposure differences were also observed for clozapine, quetiapine fumarate, amitriptyline hydrochloride, mirtazapine, nortriptyline hydrochloride, fluoxetine hydrochloride, fluvoxamine maleate, paroxetine hydrochloride, and venlafaxine hydrochloride; however, these differences were marginal, ambiguous, or based on less than 3 independent studies. Conclusions and Relevance: In this systematic review and meta-analysis, the association between CYP2C19/CYP2D6 genotype and drug levels of several psychiatric drugs was quantified with sufficient precision as to be useful as a scientific foundation for CYP2D6/CYP2C19 genotype-based dosing recommendations.

RESUMO

Introduction: Prescribing trends in maintenance therapy of patients with primary psychotic disorders (PSD) may vary worldwide. Present study aimed to investigate prescription patterns in a sample of outpatients with PSD from Serbia.Methods: In a sample of 73 PSD outpatients we analysed the rate of antipsychotic polypharmacy and psychotropic polypharmacy, concomitant continual benzodiazepine use, and associations between therapy, psychotic symptoms and quality of life.Results: Maintenance therapy (median daily dose 321 mg of chlorpromazine equivalents) predominantly consisted of monotherapy with second generation antipsychotics (45.2%), followed by antipsychotic polypharmacy based on first and second generation combination (25.0%). The median number of psychotropic drugs was 3. Benzodiazepines were continually prescribed to more than 60% of patients (mean daily dose 2.9 ± 2.0 mg lorazepam equivalents). Patients with benzodiazepine use had significantly more psychotropic medications and more antipsychotic polypharmacy, poorer quality of life and more severe psychopathology in comparison to another group.Conclusion: The present study demonstrated new information regarding the prescription patterns of psychotropic drugs in outpatients with PSD in Serbia, amplified with clinically relevant information. This study also revealed distinct prescription patterns concerning antipsychotic/benzodiazepine polypharmacy. Overall, such findings are likely to contribute to improving clinical practice and care for patients with PSD in general.KeypointsPresent exploratory research aimed to elucidate trends of antipsychotics polypharmacy and concomitant use of psychotropic medications including benzodiazepines in the maintenance treatment of outpatients with schizophrenia and other psychotic disorders, amplified with clinically relevant information (symptoms and quality of life).'Antipsychotic (AP) polypharmacy' was defined as concurrent use of more than one AP for at least 1 month; 'Psychotropic polypharmacy' was defined as the combination of AP and a different class of psychotropic drugs medication for at least one month.The median number of prescribed psychotropic drugs was 3 (mean 3.1 ± 1.1) and the average AP daily dose was moderate (median 321 mg of chlorpromazine equivalents). However, the rates of AP polypharmacy (45.2%) and benzodiazepine prescription on a continual basis (>60%) found in our sample could be considered relatively high.Outpatients with higher AP daily dose and higher BPRS symptom score were receiving more benzodiazepines.For improvement of the local, as well as general clinical practice and care for patients with psychotic disorders, and for education in psychiatry, such analyses need to be done on a regular basis and on larger samples.

RESUMO

BACKGROUND: Structural retinal architecture in living organisms became measurable with the development of optical coherence tomography (OCT) scanners. Single-layer analysis with spectral-domain OCT, among other techniques, may provide further insight into pathological changes in complex brain disorders such as psychosis spectrum disorders (PSD). METHODS: This study investigated potential thinning of retinal layers (retinal nerve fiber layer - RNFL, macular volume, macular thickness, ganglion cell-inner plexiform layer- GC-IPL, optic cup volume and cup-to-disk ratio) using a spectral-domain OCT device in 33 non-acute PSD patients (illness duration 5.9 ± 3.9 years) and 35 healthy controls. RESULTS: In comparison to age and gender matched controls, patients had bilateral reductions in GC-IPL layer thickness and macular volume. Macular central subfield thinning was found in the right eye, while average macular thickness was lower in the left eye only. RNFL thinning was not observed in patients in comparison to controls, but we noticed that status of this layer could be affected by daily dose of antipsychotics and by illness duration. CONCLUSION: Taken together, our results reveal that retinal thinning is present in young adults with PSDs, but in comparison to the literature we found more prominent changes in both GC-IPL and macular volume/thickness, than in RNFL. Our findings may reflect synaptic loss and neuronal atrophy in non-acute young patients with psychosis.

RESUMO

BACKGROUND: Previous studies examining sex-differences in facial emotion recognition (FER) in psychosis yielded inconsistent results. Although females are considered to be superior in FER in health, it remains unclear whether the specific sex-difference is present in psychosis. We aimed to examine whether women and men differ in FER ability in health and in psychosis, and to explore potential sex differences in the illness' effects on FER. METHODS: Remitted psychotic patients and controls were assessed using the CANTAB Emotion Recognition Task (ERT) examining accuracies/response latencies in identifying basic emotional expressions. General linear model was performed to assess the effects of group, sex and their interactions on ERT performance. RESULTS: Healthy females showed FER advantage in comparison to healthy males, while the aforementioned sex-difference was not observed in remitted psychotic patients. Our results also demonstrated the existence of overall FER deficit in psychosis in comparison to healthy controls, as well as the differential illness' effects on the recognition accuracy of facial expression of anger in males and females-suggesting that females with psychotic disorders undergo more profound deterioration of FER ability than their male counterparts. CONCLUSION: The assessment of sex-differences in FER and other important features of psychosis is important for better understanding of its neurobiological basis and for the development of targeted treatments for improved functioning.

RESUMO

Childhood trauma (CT) increases the risk for psychopathology through disturbed acquisition and extinction of fear. The effects of CT are mediated by abnormalities of the hypothalamic-pituitary-adrenal axis and glucocorticoid receptor (GR). Since, the alterations in GRα translational isoforms have been documented in psychiatric disorders we sought to: 1) explore whether multiple GRα isoforms in the human peripheral blood mononuclear cells of two independent cohorts (whole cell n = 40; and nuclear extracts n = 43, adult subjects) mediate the effect of CT on negative affectivity (NA) measured by Depression, Anxiety and Stress Scales (DASS), and 2) examine their role/function during fear extinction in the animal model. In multiple regression analysis, CT, nuclear 40-kDa GRα, their interactions and FKBP5 explained 22%-35% of variance in DASS scores. Structural equation modeling showed that CT had a significant direct effect on 40-kDa and DASS in both cohorts, and on the nuclear 25-kDa GRα. The association between 40-kDa and total DASS was significantly mediated by nuclear FKBP5, whereas on DASS anxiety, over FKBP5 in both cohorts and nuclear full length GRα. Nuclear 40-kDa GRα and its interaction with CT had a significant direct effect on DASS anxiety. In mice, the successful extinction learning was followed by nuclear translocation of 40-kDa GRα and induction of BDNF exon IV expression. Our data revealed that the association between CT and adult NA in non-clinical subjects is mediated by the GRα translational isoforms, in particular 40-kDa GRα, and emphasized its role in fear extinction and neural plasticity.

RESUMO

INTRODUCTION: Frontonasal dysplasia is a rare condition of congenital structure malformations of the midface. Ophthalmologic abnormalities have been estimated to occur in 87% of cases of frontonasal dysplasia. CASE REPORT: We report a case of type I frontonsal dysplasia in a 15-year old boy after the correction of severe hypertelorism, median nasal cleft w~ith a broad nasal root and associated decompensated intermittent exotropia with overaction. of the inferior oblique muscles and V pattern. He underwent bilateral lateral rectus recessions of 6.0 mm for intermittent exotropia when he was six years old. The correction of hypertelorism was performed with orbital rotation surgery when he was thirteen years old. For some time after strabismus surgery, the ocular alignment improved, but it deteriorated gradually. The ocular alignment improved after the hipertelorismus correction; however, intermittent exotropia deteriorated gradually again six to seven months later. On the last ophthalmologic examination, he had the ocular alignment on the level of small angle exotropia and associated hypertropia and occasionally even.small angle esotropiaat near. There was bilateral overelevation in addiction and V pattern, which remained unchanged after extensive facial bones surgical procedures. CONCLUSION: The high incidence of ocular abnormalities, particularly exodeviations, indicates that the early assessment by an ophthalmologist should be a part of the initial evaluation of patients with frontonasal dysplasia to detect treatable visual or ocular problems.

RESUMO

OBJECTIVES: To develop a structural equation model of negative affectivity (NA) that involves interaction of glucocorticoid receptor (GR) signaling, personality dimensions and recent stressful life events. METHODS: Seventy participants - 35 diagnosed with major depression and 35 healthy controls, were enrolled in the study. Morning plasma cortisol levels were determined by chemiluminescent immunometric assays. Molecular parameters (total nuclear and cytoplasmatic GR, nuclear GR phosphorylated at serine 211 (pGR-211) and at serine 226 (pGR-226) and cytoplasmic FKBP51) were analysed from peripheral blood lymphocytes by Western blot. NA, personality dimensions and stressful life events were assessed by self-report instruments. RESULTS: GR signalling parameters had direct independent effect on measures of NA, with pGR-226 levels showing the strongest correlation, followed by FKBP51 and pGR-211 levels. Neuroticism and extraversion also demonstrated strong independent effect on NA, while recent stressful events did not predict NA directly, but demonstrated a significant effect on personality dimensions. Cortisol, total nuclear GR and total cytoplasmatic GR levels were excluded from the model due to non-significant correlations with NA. CONCLUSIONS: Negative affectivity is a transdiagnostic factor in vulnerability to affective disorders and possible therapeutic target. Molecular signature of negative affectivity should incorporate GR phosphorylation with other known biological underpinnings.

RESUMO

The introduction of antipsychotic medication in the 1950s forever changed the outlook on the treatment of schizophrenia, although there is still a large proportion of patients who do not reach functional recovery. At least 30% of patients do not respond to clozapine, the tricyclic dibenzodiazepine with complex pharmacological actions, which was proven to be more effective than any other antipsychotic in the treatment of schizophrenia. According to most of the therapeutic guidelines for schizophrenia, clozapine is the third line therapy for patients who did not respond to other antipsychotics. Large inter-individual variability exists for clozapine bioavailability and plasma steady-state concentrations and clearance. Clozapine is metabolized by the cytochrome P450 oxidase enzyme family (CYP450). Cytochrome P450 1A2 (CYP1A2), which is polymorphically expressed in humans, is the main enzyme of clozapine metabolism. This case report addresses the influence of CYP1A2*1F genetic polymorphism on clozapine metabolism, explains the primary non-response of a young patient with schizophrenia due to increased gene expression in homozygous genotype *1F/*1F (increased metabolism of clozapine) and underlies the importance of personalizing schizophrenia treatment by means of genetic and other molecular tools, at least in the cases of ¼treatment resistance«.

RESUMO

BACKGROUND: Oxidative stress is reliably observed in major depressive disorder (MDD). However, molecular data on the principal cellular redox-sensitive transcriptional factors and the levels of their downstream-regulated antioxidant enzymes in MDD are scarce. METHODS: In the peripheral blood mononuclear cells (PBMC) of subjects with a current episode of MDD (n = 30) and healthy controls (n = 35), we investigated alterations in the levels of redox-sensing nuclear factor (erythroid-derived 2)-like 2 (Nrf2) protein, its inhibitor Keap1, and nuclear factor-κB (NF-κB), along with their cognate downstream effectors, the antioxidant enzymes (AOEs): manganese and copper zinc superoxide dismutase (MnSOD and CuZnSOD, respectively), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GLR). RESULTS: MDD subjects exhibited higher levels of Nrf2 and its regulator Keap1, as well as NF-κB in the cytoplasm of PBMC compared to controls. This state was further reflected by increased levels of MnSOD, CuZnSOD and CAT proteins and by the lack of correlation between MnSOD and CAT, which could indicate impaired oxidative detoxification capacity in MDD patients. Moreover, increased levels of MnSOD, CuZnSOD and CAT in MDD patients positively correlated with levels of Nrf2, while increased levels of SODs were also positively related to NF-κB. There were no differences regarding the levels of GPx and GLR proteins, but the ratio of GLR/GPx was reduced, suggesting diminished capacity of GPx in antioxidative defence in PBMC of MDD subjects. CONCLUSION: These data provide evidence that MDD is characterized by up-regulation of redox-sensitive transcriptional factors (Nrf2 and NF-κB) and AOEs (MnSOD, CuZnSOD and CAT), indicating pro-oxidative state in the PBMC of MDD patients.

RESUMO

The mechanism of maladaptive chronic stress response involves altered phosphorylation of the glucocorticoid receptor (GR). In this study, we investigated if important depressogenic vulnerability factors, such as neuroticism and self-reports of negative affective states, may be associated with alterations in levels of the GR and GR phosphoisoforms in peripheral blood mononuclear cells (PBMC) of healthy adults. In 21 women and 16 men we evaluated PMBC levels of total GR (tGR), GR phosphorylated at serine 211 (pGR-S211) and serine 226 (pGR-S226) and correlated these data with personality traits and current reports of stress, anxiety and depression. Also, we assessed plasma cortisol levels in all tested subjects. Our results showed that in women nuclear pGR-S226 was positively correlated with neuroticism and current reports of depression, anxiety and stress, while the ratio of nuclear pGR-S211/pGR-S226 was negatively correlated with reports of depression. None of the aforementioned correlations were significant in men. No significant relations between cortisol levels and any of GR parameters were observed. These preliminary findings highlight the value of GR phosphorylation-related research in identifying molecular biomarkers of depressogenic vulnerability, at least in women.

RESUMO

The impaired glucocorticoid receptor (GR) signaling has long been considered one of the cornerstones in understanding the pathophysiology of depression. Since the phosphorylation of GR is very important for GR function, in this study we investigated whether GR phosphorylation at serine 211 (pGR-S211) and serine 226 (pGR-S226) is altered in patients with current episode of major depressive disorder (MDD). Particularly, in 30 MDD patients and 35 controls we assessed the levels of nuclear total GR (tGR), pGR-S211 and pGR-S226 in peripheral blood mononuclear cells (PBMC) using Western blot technique, along with plasma cortisol concentrations from the same blood samples. Our results demonstrated increased phosphorylation of GR at S226 (p<0.001) and, to a less extent, at S211 (p<0.05) in MDD patients compared to controls. Consequently, the pGR-S211/pGR-S226 ratio was decreased (p<0.05) implying reduced transcriptional activity of GR in MDD patients. MDD subjects had higher cortisol levels than controls and cortisol concentrations were positively correlated with PBMC pGR-S226 levels from the same blood samples. There was no difference in the levels of tGR between MDD and control subjects. The study showed that altered phosphorylation of GR could contribute to impaired GR function related to the pathophysiology of depression.

RESUMO

BACKGROUND/AIM: Antidepressants are a widely used class of drugs. The aim of this study was to investigate different aspects of antidepressant prescribing practice at University Psychiatric Clinic in Belgrade. METHODS: This cross-sectional study was carried out by retrospective analysis of the patient's medical charts. The study included all patients with antidepressant prescribed at discharge during 2009 (n = 296). The evaluation was focused on patient-related factors (socio-demographic and illness related), psychiatrist-related factors (sex and duration of working experience) and drug related factors (type of antidepressant, dose, polypharmacy and reimbursement by national health insurance). RESULTS: Antidepressants were prescribed for unipolar depression (F32-34, ICD X) either without comorbidity (46.2%) or with comorbidity (24.7%), mostly as a monotherapy (91% had one antidepressant), to the patients who were 65% female, aged 50.1 +/- 8.9, most of them with 12 years of education (52.6%), married (69.3%) and employed (55.9%). The majority of patients had a history of two hospitalizations (Med 2; 25th-75th perc. 1-4) during nine years (Med 9; 25th-75th perc. 2-15) after the first episode of depression. Among them, 19% were found to be suicidal in a lifetime. The single most prescribed antidepressant was sertraline (20.4%), followed by fluoxetine (13.3%) and maprotiline (11.7%). Utilization of antidepressants was positively correlated with the rate of reimbursement (p < 0.01). The most prescribed antidepressant group was selective serotonin reuptake inhibitors (SSRI) (47.8%), followed by tricyclic antidepresants (TCA) (25.3%) and new antidepressants - venlafaxine, tianeptine, mirtazapine, bupropion, trazodone (15.1%). Most of the drugs were prescribed in doses which are at the lower end of the recommended dose-range. Regarding severity of the actual depressive episode, TCA were prescribed for severe depression with psychotic features, while SSRI were choice for episodes with moderate symptom severity (p = 0.01). Psychiatrists with longer working age (20-30 years) hesitated to prescribe new antidepressants in comparison to younger colleagues (p = 0.01). CONCLUSION: Economic issues in Serbia as developing country influence the choice of antidepressants, as well as a psychiatrist's working age and severity of depression. However, SSRI are the drugs of the first choice, as it was shown in most of the developed countries nowadays.

RESUMO

BACKGROUND: Stigmatization of psychiatric patients is present both in the general population and among healthcare professionals. AIM: To determine the attitudes and behaviour of medical students towards a person who goes to a psychiatrist, before and after psychiatric rotation, and to compare those attitudes between medical and non-medical students. METHODS: The study included 525 medical students (second and sixth year of studies) and 154 students of law. The study instrument was a three-part self-reported questionnaire (socio-demographic data, Rosenberg Self-Esteem Scale and a vignette depicting a young, mentally healthy person). The experimental intervention consisted of ascribing a 'psychiatric label' to only one set of vignettes. All the vignettes (with or without the 'psychiatric label') were followed by 14 statements addressing the acceptance of a person described by vignette, as judged by social distance (four-point Likert scale). RESULTS: Higher tendency to stigmatize was found in medical students in the final year, after psychiatric rotation (Z(U) = -3.12, p = .002), particularly in a closer relationship (Z(U) = -2.67, p = .007) between a student and a hypothetical person who goes to a psychiatrist. The non-medical students had a similar tendency to stigmatize as medical students before psychiatric rotation (Z(U) = -0.03, p = .975). Neither gender, nor the size of student's place of origin or average academic mark was associated with the tendency to stigmatize in our sample. However, student's elf-esteem was lower in those with a tendency to stigmatize more in a distant relationship (ρ = -0.157, p = .005). CONCLUSIONS: Psychiatric education can either reinforce stigmatization or reduce it. Therefore, detailed analyses of educational domains that reinforce stigma will be the starting point for anti-stigma action.

RESUMO

OBJECTIVE: To prospectively evaluate depressive symptoms and risk factors for depression in patients with chronic hepatitis C (CHC) treated with pegylated interferon alpha therapy combined with oral ribavirin (PEG-IFN-α+RBV) and to analyze self-rating scale for depression in comparison to observer-based scale in the given population. SUBJECTS AND METHODS: The Hamilton Depression Rating Scale and Zung Self Rating Depression Scale were used to screen for depressive symptoms in 74 subjects with CHC before PEG- IFN-α (mean dose 152.6±25.6 mcg), and in the follow-up visits (4, 12 and 24 week). RESULTS: Incidence of depressive symptoms in patients (mean age 39.9±13.4 years; equal sex distribution p=0.225) treated by PEG- IFN-α was the highest on 12th week of the treatment, when more than a 20% of our sample had moderate/severe symptoms of depression, and about 30% had minor depressive symptoms. For the screening of depression during PEG- IFN-α self-assessment scale was equally reliable as observer-based assesment of depressive symptoms. Common clinical parameters- subject related risk factors (age (p=0.955 ), sex (p=0.008), lifetime psychiatric disorder (p=0.656)), illness related risk factors (duration of CHC (p=0.267 ), i.v drug aplication as way of transmission (p=0.292)) and therapy-related risk factors (recommended duration of PEG-IFN-α (p=0.993) and dose of PEG-IFN-α (p=0.841)) were not signifcantly associated with depressive symptoms on PEG-IFN-α. CONCLUSIONS: Liason-consultation services should collaborate with hepatologists in creating screening programmes, supplemented by objective criteria and guidelines, for early recognition and treatment of interferon-induced depression.

RESUMO

BACKGROUND/AIM: So far, studies of stress have shown that physicians are at a high risk of sickness from psychic and somatic disorders related to professional stress, that can lead to important disturbance of personal, familiar and professional functionating. The aim of this study was to investigate the doctors exposition level to professional stress, to compare stress level in general practitioners (GP) group with that in the group of psychiatrists and risk level for the apperance of burnout syndrome. METHODS: This cross-section study included subjects recruited by a random sample method. Thirty General Practice doctors and 30 psychiatrists (totally 60 doctors) filled the set of 3 questionnaires: Sociodemographics features, General Health Questionnaire (GHQ; Goldberg D, 1991), and Maslach Burnout Inventory (MBI; Maslach C, 1996). Appropriate statistical procedures (Pearson test, t-test, variance analysis) in interpretation of the results were used. RESULTS: A total level of psychic distress measured with the GHQ test in both groups of physicians was very low implying their good mental health. A difference in Burnout risk based on MBI test between the groups was statistically significant (chi2 = 4,286; p < 0.05) only at subscale Personal Accomplishment (MBI-PA); it was a consequence of a higher number of GPs with medium burnout risk (13.3 : 0.0%). However, even 35 physicians from the sample were affected with a high burnout risk measured with subscales Emotional Ehausation (MBI-EE) and MBI-DP, showing that both groups of physicians had risk for the appearance of burnout syndrome. CONCLUSION: The obtained results showed a high burnout risk level in both, GPs and psychiatrists, groups. In both groups there was no presence of psychic disorders (anxiety, depression, insomnia), while there was a high level of emotional ehausation and overtension by job, and also a lower total personal accomplishment. Level of exposition to professional stress is higher in GPs than in psychiatrists, but the difference was not statistically significant.

RESUMO

INTRODUCTION: Alcoholism is one of the most frequent modern diseases. These kinds of epidemiological studies have not been carried out in this country at a global level. OBJECTIVE: The aim of the study was to establish the spread of alcohol abuse among the young regarding the sex, and find the connection between the alcohol abuse and the consumption of drugs and cigarettes. METHODS: The study was carried out among the elementary school pupils of the seventh and eighth grade in the area of Belgrade from October 2003 to January 2004. Total of 457 pupils were involved; 229 (50.1%) were boys and 228 (49.9%) girls, aged 12-15 years, the average age being 13.4 years. The method used was the modified questionnaire European School Survey Project on Alcohol and Other Drugs, which the pupils filled in individually, voluntarily and anonymously. Chi2-test, Student's t-test, Mann-Whitney Logistic Regression Test were used in statistical processing of the data. RESULTS: Almost 70% of the examinees have tried alcohol. Most of the examinees had the first contact with alcohol at the age of 11. Half of our examinees got drunk at least once in their life and about one fifth more than 20 times. The binge form of Consumption (five or more drinks in a row) was evident in a quarter of our examinees. Our examinees use alcohol together with other psychoactive substances, mostly marijuana. It was observed that certain types of behaviour, such as frequent going out in the evening, were directly related to the abuse of alcohol. CONCLUSION: Two thirds of the examinees have tried alcohol. The first contact with alcohol is shifted to an earlier age (11 years). New trends of alcohol abuse have been noticed, such as binge form of consumption and the connection of use with other psychoactive substances.

RESUMO

BACKGROUND/AIM: Socio-economic changes that occured in the wake of dismemberment of former Yugoslavia resulted in the appearance of social pathology, one of which was the increase in the use of psychoactive substances. The overwhole epidemiological research in the use of psychoactive substances has not been conducted so far. The aim of this study was to establish the type and form of the use of psychoactive substances considering sex and age, as well as risk factors for the use of psychoactive substances among the children and adolescents. METHODS: The research was carried out among 1011 elementary school children (seventh and eighth grades) and secondary school children (all four grades) in the area of Belgrade from October 2003 to January 2004. Out of the total number 457 (45.2%) were elementary school pupils and 554 (54.8%) secondary school pupils. There were 524 (51.8%) boys and 487 (48.2%) girls, aged from 12 to 18 years (the average age being 15.3 years). The method used was the European School Survey Project on Alcohol and Other Drugs Questionaire. Chi-square test, Mann-Whitney, Student's t test and Logistic Regression test were used in statistical processing of the data. RESULTS: Totally 14.2% examinees tried psychoactive substances. The most frequent drug used at the first contact was marijuana (10.8%) at the age of 15 tried by 12.7% examinees, inhalants (4.4%), amphetamines (4.1%), sedatives (3.7%), alcohol combined with marijuana (3.9%), then cocaine (2.8%), heroine (2.3%), alcohol combined with sedatives (2.2%), and ecstasy (1.6%), followed by anabolic steroids, heroin, diethilamid lisergic acid (LSD) and magic mushrooms. It was determined that going out in the evening, smoking and binge form drinking were directly connected with the use of psychoactive substances. CONCLUSION: Totally 14.2% of the exameneers used psychoactive substances, mostly marijuana, followed by amphetamines and others. New tendencies of use characterized by the increase in the use are of synthetic substances, simultaneous use of more psychoactive substances and younger age. The risk factors are going out in the evening, smoking, binge drinking and use of synthetic substances among peers. Our research indicates the neccessity of primary prevention.
