Abstract
Peroxisome proliferator-activated receptor alpha (PPARα) and antipsychotic medications both influence polyunsaturated fatty acids (PUFA) homeostasis, and thus PPARα polymorphism may be linked to antipsychotic treatment response. Here we investigated whether the functional leucine 162 valine (L162V) polymorphism in PPARα influenced antipsychotic treatment in a group of psychosis patients (N = 186), as well as in a patient subgroup with risperidone, paliperidone, or combination treatment (N = 65). Antipsychotic-naïve first-episode patients and nonadherent chronic individuals were genotyped by polymerase chain reaction analysis. At baseline, and after 8 weeks of treatment with various antipsychotic medications, we assessed the patients' Positive and Negative Syndrome Scale (PANSS) scores; PANSS factors; and metabolic syndrome-related parameters, including fasting plasma lipid and glucose levels, and body mass index. In the total patient group, PPARα polymorphism did not affect PANSS psychopathology or metabolic parameters. However, in the subgroup of patients with risperidone, paliperidone, or combination treatment, PPARα polymorphism influenced changes in plasma LDL cholesterol. Specifically, compared to PPARα-L162L homozygous patients, PPARα-L162V heterozygous individuals exhibited significantly higher increases of LDL cholesterol levels after antipsychotic treatment. The PPARα polymorphism had a strong effect size, but a relatively weak contribution to LDL cholesterol level variations (∼12.8 %).

Abstract
Here we investigated whether antipsychotic treatment was influenced by three polymorphisms: rs10798059 (BanI) in the phospholipase A2 (PLA2)G4A gene, rs4375 in PLA2G6, and rs1549637 in PLA2G4C. A total of 186 antipsychotic-naïve first-episode psychosis patients or nonadherent chronic psychosis individuals (99 males and 87 females) were genotyped by polymerase chain reaction analysis/restriction fragment length polymorphism. At baseline, and after 8 weeks of treatment with various antipsychotic medications, we assessed patients' Positive and Negative Syndrome Scale (PANSS) scores, PANSS factors, and metabolic syndrome-related parameters (fasting plasma lipid and glucose levels, and body mass index). We found that PLA2G4A polymorphism influenced changes in PANSS psychopathology, and PLA2G6 polymorphism influenced changes in PANSS psychopathology and metabolic parameters. PLA2G4C polymorphism did not show any impact on PANSS psychopathology or metabolic parameters. The polymorphisms' effect sizes were estimated as moderate to strong, with contributions ranging from around 6.2-15.7%. Furthermore, the polymorphisms' effects manifested in a gender-specific manner.

Abstract
Major depressive disorder is one of the most common mental illnesses that highly impairs quality of life. Pharmacological interventions are mainly focused on altered monoamine neurotransmission, which is considered the primary event underlying the disease's etiology. However, many other neuropathological mechanisms that contribute to the disease's progression and clinical symptoms have been identified. These include oxidative stress, neuroinflammation, hippocampal atrophy, reduced synaptic plasticity and neurogenesis, the depletion of neurotrophic factors, and the dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis. Current therapeutic options are often unsatisfactory and associated with adverse effects. This review highlights the most relevant findings concerning the role of flavonols, a ubiquitous class of flavonoids in the human diet, as potential antidepressant agents. In general, flavonols are considered to be both an effective and safe therapeutic option in the management of depression, which is largely based on their prominent antioxidative and anti-inflammatory effects. Moreover, preclinical studies have provided evidence that they are capable of restoring the neuroendocrine control of the HPA axis, promoting neurogenesis, and alleviating depressive-like behavior. Although these findings are promising, they are still far from being implemented in clinical practice. Hence, further studies are needed to more comprehensively evaluate the potential of flavonols with respect to the improvement of clinical signs of depression.

Abstract
Clozapine is considered the gold standard for patients with treatment-resistant schizophrenia (TRS) who have previously tried other antipsychotics at adequate doses (two or more, with at least one being atypical). However, despite optimal treatment, a subgroup of TRS patients with what is known as ultra-treatment-resistant schizophrenia (UTRS) fails to respond to clozapine, which occurs in 40–70% of cases. The most common approach to manage UTRS involves augmenting clozapine with pharmacological or non-pharmacological interventions, with a growing body of evidence that supports the use of electroconvulsive therapy (ECT) as an augmenter. This prospective non-randomized 8-week study, which followed the TRIPP Working Group guidelines and is one of few that separate TRS from UTRS, aimed to evaluate the effectiveness of clozapine in TRS patients and the efficacy of ECT augmentation of clozapine in UTRS patients. Patients with TRS were assigned to receive clozapine alone (clozapine group), whereas UTRS patients received bilateral ECT in addition to their current medication regimen (ECT plus clozapine group). The severity of symptoms was evaluated using the Clinical Global Impression Scale (CGI) and Positive and Negative Syndrome Scale (PANSS) at baseline and at the end of the 8-week trial. Both treatment approaches resulted in improved CGI and PANSS scores. The results suggest that both clozapine and ECT are effective treatment options for patients with TRS and UTRS, respectively, and that adherence to guidelines should provide a better frame for future clinical studies.

Abstract
Daridorexant belongs to a class of drugs known as dual orexin receptor (OX1R and OX2R) antagonists. It achieves its function by blocking the binding of wake-promoting neuropeptides orexins. This novel mechanism is believed to turn down overactive wakefulness and as we know so far, most other treatments for insomnia can be sedating.

Abstract
The paper deals with a case report of a 41-year-old man who in search of the meaning of life in a so-called “shamanic ritual” drank tea made from the San Pedro cactus as well as paste made of the same plant. The hallucinations were post poned and started after 9.5 hours caracterised by a psychotic reaction with symptoms of catatonia. He was admitted to our Department of Psychiatry where he was administered a second generation antipsychotic. The clinical presentation disappeared about 60 hours after the ingestion of mescaline mainly because of the antagonistic effect the antipsychotic has on the serotoninergic 5-HT2A receptors.

Abstract
BACKGROUND We investigated the potential use of SPECT quantification in addition to qualitative brain perfusion analysis for the detection of anti-NMDAR encephalitis. The question is how to normalize brain activity to be able to quantitatively detect perfusion patterns. Usually, brain activity is normalized to a structure considered unaffected by the disease. METHODS Brain [99mTc]-HMPAO SPECT was performed as a method to detect brain perfusion patterns. The patterns of abnormal brain perfusion cannot always be reliably and qualitatively assessed when dealing with rare diseases. Recent advances in SPECT quantification using commercial software have enabled more objective and detailed analysis of brain perfusion. The cerebellum and whole brain were used as the normalization structures and were compared with visual analysis. RESULTS The quantification analysis performed with whole brain normalization confirmed right parietal lobe hypoperfusion while also detecting statistically significant left-to-right perfusion differences between the temporal lobe and thalamus. Whole brain normalization further described bilateral frontal lobe hyperperfusion, predominantly of the left lobe, and was in accordance with visual analysis. CONCLUSION SPECT quantitative brain perfusion analysis, using the whole brain as the normalization structure rather than the cerebellum, in this case, improved confidence in the visual detection of anti-NMDAR encephalitis and provided unexpected solutions to atypical psychiatric dilemmas.

Abstract
BACKGROUND To assess potential benefits of quetiapine for persistent sleep disturbances in patients with posttraumatic stress disorder (PTSD) on stable combined SSRI and benzodiazepine therapy, who previously failed to respond to various benzodiazepine and non-benzodiazepine hypnotic adjuvant treatment as well as to first-generation antipsychotic add-on treatment. SUBJECTS AND METHODS Fifty-two male PTSD outpatients on stable combination treatment with SSRI and benzodiazepines, with persistent sleep disturbances not responding to prescription of zolpidem, flurazepam, nitrazepam, promazine, and levopromazine, were assessed for sleep disturbances improvements after prescription of quetiapine in the evening. Each patient met both ICD-10 and DSM-IV criteria for PTSD. Psychiatric comorbidity and premorbidity were excluded using the Mini-International Neuropsychiatric Interview (MINI). Improvement on the CAPS recurrent distressing dream item, reduction in the amount of time needed to fall asleep, prolongation of sleep duration, and reduction in average number of arousals per night in the last 7 days before the assessment period were used as efficacy measures. RESULTS All sleep-related parameters improved significantly at the end of a five-week follow-up: sleep duration increased by one hour (p<0.001), sleep latency decreased by 52.5 minutes (p<0.001), median number of arousals per night decreased from two to one (p<0.001), CAPS recurrent distressing dream item median decreased from five to four (p<0.001), and the number of patients dissatisfied with their sleep quality and quantity decreased from 45 to two (p<0.001). CONCLUSION Quetiapine prescribed in the evening may be successful therapy for persistent sleep disturbances in patients with PTSD and generally good response to an SSRI and benzodiazepine combination, who previously failed to respond to some of the usual hypnotic medication or addition of first-generation antipsychotics: zolpidem, flurazepam, nitrazepam, promazine, and levopromazine.

Abstract
Objective Schizophrenia is a debilitating disease that disrupts the lives of many affected individuals and exerts a toll on the health system. Only few studies assessed once-monthly injectable formulation of paliperidone palmitate (PP-1M) and other long-acting antipsychotics in recent onset schizophrenia (ROS). To evaluate whether PP-1M is efficacious in reducing frequency and length of hospitalizations and psychosis symptom severity in patients with ROS. Methods This mirror-image study included 112 patients, suffering from ROS admitted in a psychiatric ward and successively treated with PP-1M for 1-year. Other psychotic disorders were excluded. We collected socio-demographic data of all subjects included, number and days of hospitalization, as well as Clinical Global Impression-Severity scale (CGI-S) and Clinician-Rated Dimensions of Psychosis Symptom Severity (CRDPSS) scores at the initiation and after 1-year of PP treatment. Results After 1-year PP-1M treatment, mean scores of both CGI and CRDPSS significantly decreased (p < 0.001), as well as the mean number of hospitalizations (p = 0.002) and total hospitalization days (p < 0.001) in comparison with those of the previous year. Conclusion Our results suggest that PP-1M can be considered as an important therapeutic option in patients with ROS. Its use led to a meaningful reduction in the patient’s use of hospital services, as well as a significant clinical improvement of psychotic symptoms in our sample.

Abstract
Genetic and nongenetic factors associated with an increased inflammatory response may mediate a link between severe coronavirus disease 2019 (COVID‑19) and serious mental illness (SMI). However, systematic assessment of inflammatory response‑related factors associated with SMI that could influence COVID‑19 outcomes is lacking. In the present review, dietary patterns, smoking and the use of psychotropic medications are discussed as potential extrinsic risk factors and angiotensin‑converting enzyme (ACE) insertion/deletion (I/D) gene polymorphisms are considered as potential intrinsic risk factors. A genetics‑based prediction model for SMI using ACE‑I/D genotyping is also proposed for use in patients experiencing severe COVID‑19. Furthermore, the literature suggests that ACE inhibitors may have protective effects against SMI or severe COVID‑19, which is often linked to hypertension and other cardiovascular comorbidities. For this reason, we hypothesize that using these medications to treat patients with severe COVID‑19 might yield improved outcomes, including in the context of SMI associated with COVID‑19.

Abstract
In March 2020, three months after the first cases surfaced in the Chinese city of Wuhan, WHO declared a global pandemic of the novel coronavirus, which by than had already spread through a great number of countries all over the world. In order to protect the health of healthcare workers and patients, activities and measures of disease prevention have been taken; in such circumstances, psychiatry found itself faced with various challenges, one of them being the preservation of the continuity of electroconvulsive therapy (ECT) in patients with severe or refractory psychiatric disorders. Such patients are a priority and demand immediate treatment in hospital settings adapted to epidemiological circumstances. Having studied the instructions and recommendations of the competent authorities, as well as reviewing available literature, this paper presents the most important measures for the smooth performance of ECT in conditions associated with the COVID-19 disease.

Abstract
RATIONALE Beneficial effects of aripiprazole on cognition in schizophrenia have been previously reported, but not in recent onset schizophrenia. Cognitive impairments have also been associated with catechol-O-methyltransferase (COMT), methylenetetrahydrofolate reductase (MTHFR), and serotonin transporter (SERT) gene polymorphisms which were earlier implicated in the pathophysiology of schizophrenia. OBJECTIVES This study examined the short-term influence of aripiprazole long-acting injectable (LAI) as well as of COMT, MTHFR, and SERT gene polymorphisms and their interactions on clinical features and cognitive functions in inpatients with recent onset schizophrenia. METHODS This study included 98 inpatients suffering from recent onset schizophrenia diagnosed according to DSM-5 criteria. Three months after initiating aripiprazole LAI, the severity of symptoms was assessed by the Positive and Negative Syndrome Scale (PANSS), while cognitive functions were measured by 5-KOG test for cognition. Genotypes of SERT, MTHFR, and COMT gene were determined by different polymerase chain reaction (PCR) methods. RESULTS Three-month aripiprazole LAI treatment was associated with a statistically significant change of PANSS total (p<0.001) and subscale scores as well as cognitive parameters of delayed recall (p<0.03), attention (p<0.01), and executive functions in the form of less perseverations (p<0.03), without influencing other examined cognitive functions. However, it significantly influenced composite cognitive score (p<0.02). In regard to the investigated genetic polymorphisms, we established a positive association between the COMT polymorphism (M/M allele carriers) and attention (p<0.01). Additionally, we also established a positive association between the COMT - MTHFR interaction and attention (p<0.02), as well as perseveration item belonging to executive functions (p<0.01). Two other investigated polymorphisms (MTHFR and SERT) were not significantly associated with cognitive indices. Investigated genetic polymorphisms and their interactions were not associated with PANSS scores. CONCLUSIONS Our findings suggest that aripiprazole LAI improves individual cognitive functions in recent onset schizophrenia. Investigated COMT polymorphism (Met/Met genotype), as well as the COMT-MTHFR interaction, were positively associated with attention and executive functioning (perseveration), potentially implying COMT's biomarker potential in terms of cognition in schizophrenia.

Abstract
BACKGROUND Alcohol use disorder (AUD) is a psychiatric disorder characterized by excessive and uncontrolled drinking that causes distress and has damaging consequences for men and women of all ages. It is one of the four most disabling diseases and it affects approximately 14.6 million persons in Europe. OBJECTIVES Objective of this study is to investigate changes in platelet serotonin concentration after four weeks of alcohol abstinence in regards to the genotype of the serotonin transporter. METHODS A total of 154 patients with AUD were included in the study. Platelet serotonin concentrations were assessed by enzyme-linked immunosorbent assay. Genotype of serotonin transporter promoter polymorphism was determined by the polymerase chain reaction-based method. RESULTS We did not establish a statistically significant main effect of serotonin transporter polymorphism on platelet serotonin concentration after four weeks of abstinence. CONCLUSION Aforementioned finding is in line with previous research suggesting a complex relationship between serotonin transporter gene and platelet serotonin levels, and congruent with the well-established genotype interaction with numerous other factors, such as sex, ethnicity, education level, and stressful life events.

Abstract
OBJECTIVE Recent-onset schizophrenia (ROS) represents a critical period that can greatly influence the clinical course of schizophrenia. The use of long-acting injectable antipsychotics (LAIs) in this period is increasingly being considered as a first-line treatment option. Aripiprazole LAI (ALAI) is the newest of all LAI's available on the market, with limited data on its effects on hospitalization rates after first episode of schizophrenia. It was our goal to evaluate whether ALAI has an effect on hospitalization rates, number of bed days and clinical improvement in patients with ROS. METHODS This mirror-image study included 138 inpatients suffering from schizophrenia. We collected sociodemographic data on all individuals, number of hospitalization days, hospitalization rates as well as Clinical Global Impression Scale-severity of illness (CGI-S) and Clinician-Rated Dimensions of Psychosis Symptom Severity (CRDPSS) scores at the initiation of ALAI and at the end of a 1 year follow up. RESULTS Mean number of hospitalizations and hospitalization days in the year after starting ALAI significantly decreased compared to the year before (p = 0.005 and p < 0.001). Mean scores on both CGI and CRDPSS also significantly decreased after initiating ALAI (p < 0.001). CONCLUSION Results suggest that ALAI is an important therapeutic option in patients with ROS. It leads to reduced usage of hospital services, potentially reducing the socio-economic healthcare burden.

Abstract
INTRODUCTION Vitamin D is involved in brain development and functioning, as well as in regulation of neurotrophic factors. Changes in the expression of those factors are possibly responsible for morphologic abnormalities and symptoms in patients suffering from schizophrenia. OBJECTIVE The main goal of this research was to investigate the interrelationship between vitamin D, nerve growth factors (NGF, brain-derived neurotrophic factor [BDNF], and neuregulin-1 [NRG1]), and schizophrenia symptom domains. METHODS This research included 97 inpatients diagnosed with schizophrenia. Schizophrenia symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS). Blood samples were taken in order to analyze concentrations of vitamin D, BDNF, NRG1, and NGF growth factors. The obtained results were used in a multiple regression analysis. RESULTS The vitamin D concentration positively affected the concentration of NRG1 (F = 8.583, p = 0.005) but not the concentration of other investigated growth factors (BDNF and NGF). The clinical characteristics and symptom domains of schizophrenia seemed to be unaffected by the concentrations of vitamin D, BDNF, and NGF, while the NRG1 concentration significantly affected positive symptom domains of schizophrenia (F = 4.927, p = 0.030). CONCLUSION The vitamin D concentration positively affected NRG1 levels but not schizophrenia symptomatology as measured by PANSS. The as-sociation between the two could be intermediated via NRG1.

Abstract
Lewy body dementia is a progressive neurodegenerative disease and is considered to be the second most common cause of dementia in the elderly. Because of the complexity of clinical presentation, it is often misdiagnosed and mistaken for other dementias, which may result in administering inappropriate therapy, and thus worsening of the patient condition. We reviewed a case of a 71-year-old patient whose clinical presentation gradually occurred with complex visual hallucinations, atypical extrapyramidal motor symptoms, fluctuating cognitive impairments with delirious episodes, and oscillating syncope. Depressive mood, impaired daily functioning and sensitivity to antipsychotics were also noted. Extensive diagnostic workup was performed with neuropsychological testing and use of single-photon emission computerized tomography. Considering the clinical presentation and diagnostic procedures performed, the diagnosis of Lewy body dementia was set and pharmacotherapy was revised. We discuss the importance of taking overall clinical presentation and diagnostic treatment in consideration and applying appropriate therapy to slow down the progression of the disease and exacerbation of the patient's psychological functions.

Abstract
The use of electroretinography (ERG) and optical coherence tomography (OCT) has currently expanded beyond ophthalmology alone. The aim of this review is to present the results and knowledge acquired by these two methods in patients suffering from schizophrenia. Reviewing the studies applying ERG and OCT methods in the field of psychiatry, one can conclude that results of the research imply morphological and functional changes of retina in patients with schizophrenia that are not consistent. However, in most studies there was reduction of the amplitude and changes in the implicit time related parameters on ERG and thinning of the retinal nerve fiber layer on OCT. Neurons in the eye use the same neurotransmitters as neurons in the basal brain structures that are most affected in schizophrenia, according to the dopamine hypothesis of schizophrenia. Unlike neurons in the basal brain structures, the neurons in the eye are in vivo available to ERG. Using the aforementioned tests together with clinical diagnostic criteria of schizophrenia, the subgroups with different prognostic and therapeutic specificities within schizophrenia as a group of diseases might be identified more precisely.

Abstract
In 1937, Ugo Cerletti and Lucio Bini performed electroconvulsive treatment (ECT) in Rome for the first time. That was the time when different types of 'shock therapy' were performed; beside ECT, insulin therapies, cardiazol shock therapy, etc. were also performed. In 1938, Cerletti and Bini reported the results of ECT. Since then, this method has spread rapidly to a large number of countries. As early as 1940, just two years after the results of the ECT had been published, it was also introduced in Croatia, at Sestre milosrdnice Hospital, for the first time in our hospital and in the then state of Yugoslavia. Since 1960, again the first in Croatia and the state, we performed ECT in general anesthesia and continued it down to the present, with a single time brake.

Abstract
OBJECTIVE Impaired serotonergic neurotransmission has been implicated in the pathogenesis of depression and schizophrenia. Blood platelets have been used for years as a peripheral model of neuronal serotonin dynamics. The objective was to investigate platelet count and serotonin concentration in patients with depression and schizophrenia, in an attempt to ascertain their clinical usefulness. METHODS 953 participants were included in the study, 329 patients with depression, 339 patients with schizophrenia and 285 healthy controls. ELISA was used to assess platelet serotonin concentrations. RESULTS There were no statistically significant differences among groups regarding age, total platelet count and serotonin concentration. Linear regression analyses revealed inverse correlations between platelet serotonin concentration and age of patients with depression and healthy individuals, as well as between platelet serotonin concentration and illness duration in patients with schizophrenia. In other words, longer illness duration in patients with schizophrenia, and higher age in patients with depression and healthy individuals was associated with lower platelet serotonin concentrations. CONCLUSION Platelet count and serotonin concentration did not prove to be of diagnostic value in differentiating patients and healthy individuals. However, illness duration in patients with schizophrenia may be associated with reduced concentrations of platelet serotonin.

Abstract
We investigated the relationship between the rs10798059 (BanI) and rs4375 polymorphisms in the phospholipase A2 (PLA2)G4A and PLA2G6 genes and the risk of nicotine dependence in 263 Croatian patients with schizophrenia. We also examined whether interactions between these polymorphisms and smoking contributed to schizophrenia onset and Positive and Negative Syndrome Scale (PANSS) psychopathology. We found no significant differences in the distribution of PLA2G4A genotypes and alleles according to smoking status, and no effect of the PLA2G4A genotype-smoking interaction on disease onset or PANSS. The PLA2G6-TT homozygous genotype was significantly overrepresented in male smokers compared to nonsmokers (34.7% vs. 17.1%, p < 0.05). These patients had ∼2.6-fold higher risk of becoming smokers than males with heterozygous PLA2G6-CT and homozygous PLA2G6-CC genotypes. In addition, male smokers without the PLA2G6-C allele (PLA2G6-TT homozygous) experienced earlier onset than nonsmoking homozygous PLA2G6-TT males. Thus, the PLA2G6 polymorphism affected the risk of nicotine dependence in male patients and the PLA2G6 genotype-smoking interaction was linked to the age of disease onset.

Abstract
- The aim of the study was to test the correlation between 5-HTTLPR polymorphism and dental anxiety. Research hypothesis was that positive relation between the expression of dental anxiety and the S allele exists in the population of healthy Caucasians. We conducted a prospective study on 159 subjects, volunteers made up of medical and non-medical staff of the Sestre milosrdnice University Hospital Centre. Both genders were included, age range 19 to 59, mentally and physically healthy (according to DSM-5 classification of mental disorders). For the purpose of this research, we used a sociodemographic questionnaire containing the following information: age, gender, education level, work status, marital status and residence. Corah's Dental Anxiety Scale-Revised (DAS-R) was used to measure dental anxiety. Data distribution was tested by Kolmogorov-Smirnov test, difference between the groups by ?χ2-test and one-way analysis of variance, and correlation of variables by logistic regression. In the study population, we found positive correlation between S-allele and total result in DAS-R questionnaire. The presence of S allele suggests that the person will have a higher result in DAS-R questionnaire, i.e. higher expression of dental anxiety.

Abstract
Although depressive symptoms seem to be frequent in schizophrenia they have received significantly less attention than other symptom domains. As impaired serotonergic and dopaminergic neurotransmission is implicated in the pathogenesis of depression and schizophrenia this study sought to investigate the putative association between several functional gene polymorphisms (SERT 5-HTTLPR, MAO-A VNTR, COMT Val158Met and DAT VNTR) and schizophrenia. Other objectives of this study were to closely examine schizophrenia symptom domains by performing factor analysis of the two most used instruments in this setting (Positive and negative syndrome scale - PANSS and Calgary depression rating scale - CDSS) and to examine the influence of investigated gene polymorphisms on the schizophrenia symptom domains, focusing on depressive scores. A total of 591 participants were included in the study (300 schizophrenic patients and 291 healthy volunteers). 192 (64%) of schizophrenic patients had significant depressive symptoms. Genotype distribution revealed no significant differences regarding all investigated polymorphisms except the separate gender analysis for MAO-A gene polymorphism which revealed significantly more allele 3 carriers in schizophrenic males. Factor analysis of the PANSS scale revealed the existence of five separate factors (symptom domains), while the CDSS scale revealed two distinct factors. Several investigated gene polymorphisms (mostly SERT and MAO-A, but also COMT) significantly influenced two factors from the PANSS (aggressive/impulsive and negative symptoms) and one from the CDSS scale (suicidality), respectively. Depressive symptoms in schizophrenic patients may be influenced by functional gene polymorphisms, especially those implicated in serotonergic neurotransmission.

Abstract
Depressive symptoms seem to be frequent in schizophrenia, but so far they have received less attention than other symptom domains. Impaired serotonergic neurotransmission has been implicated in the pathogenesis of depression and schizophrenia. The objectives of this study were to investigate platelet serotonin concentrations in schizophrenic patients with and without depressive symptoms, and to investigate the association between platelet serotonin concentrations and symptoms of schizophrenia, mostly depressive symptoms. A total of 364 patients were included in the study, 237 of which had significant depressive symptoms. Significant depressive symptoms were defined by the cut-off score of 7 or more on Calgary Depression Rating Scale (CDSS). Platelet serotonin concentrations were assessed by the enzyme-linked immunosorbent assay (ELISA). Prevalence of depression in patients with schizophrenia was 65.1%. Schizophrenic patients with depressive symptoms showed lower platelet serotonin concentrations (mean±SD; 490.6±401.2) compared to schizophrenic patients without depressive symptoms (mean±SD; 660.9±471.5). An inverse correlation was established between platelet serotonin concentration and depressive symptoms, with more severe symptoms being associated with lower platelet serotonin concentrations. Depressive symptoms in schizophrenic patients may be associated with reduced concentrations of platelet serotonin.

Abstract
BACKGROUND The aim of this paper was to investigate serum concentrations of calcium-independent lipoprotein phospholipase A2 (PLA2) and protein S100 in schizophrenia patients in comparison to healthy controls and correlate them with the clinical severity, duration, and number of schizophrenia relapses. SUBJECTS AND METHODS This study included 65 schizophrenia patients and 70 controls. Schizophrenia was diagnosed according to DSM-IV-TR criteria. Clinical severity was determined by PANSS. PLA2 and protein S100 concentration were assessed by the enzyme-linked immunosorbent assay (ELISA). RESULTS PLA2 concentrations were higher in patients with schizophrenia, whereas protein S100 concentrations were not. Higher concentrations of PLA2 were positively correlated with the duration of illness and number of episodes, as determined by multivariate analysis. CONCLUSION PLA2 might be considered a possible biochemical trait marker for schizophrenia. Further research with larger and more homogeneous clinical samples is required.

Abstract
BACKGROUND Sexual self-perception is just one of the items of the complex system of self, which has rarely been researched in the population of mental health patients. OBJECTIVE Our goal was to establish whether the differences in sexual self-perception exist between schizophrenic and depressive patients compared with the healthy control group. PARTICIPANTS AND METHODS This research was performed on 100 schizophrenic patients, 100 depressive patients and 100 phenotypically healthy volunteers. In order to diagnose schizophrenia and depression, DSM-IV classification was used. Bezinovic's questionnaire for sexual self-perception was used in order to assess seven aspects of sexual self-perception. RESULTS Results revealed that schizophrenic and depressive patients, compared with healthy individuals, scored significantly higher on the aspects of negative emotionality and sexual incompetence, and significantly lower on the aspect of sexual satisfaction. No statistically significant differences were established between schizophrenic and depressive patients. CONCLUSION We can conclude that patients suffering from schizophrenia or depression differ from healthy individuals in all of the aspects of sexual self-perception.

Abstract
For the general public, but also for healthcare professionals, schizophrenia is still one of those areas of medicine connected with feelings of unease, fear and prejudice. These feelings lead to stigmatization and discrimination which are unjust processes which put patients suffering from mental illnesses into undesirable and unequal positions. Aim of this research was to establish the extent of stigmatization of mentally ill patients among the population of healthcare professionals and future healthcare professionals and if they differ from general population. Results show that stigmatization of schizophrenic patients is high among all included populations. Although there were no statistical differences between groups regarding the assessment of schizophrenic patients, nurses employed in psychiatric wards exhibited a tendency towards higher acceptance of schizophrenic patients, as well as better understanding of that illness. This data emphasizes a growing need for continuous education of general population but also of healthcare professionals.

Abstract
Aim of this research was to establish effects and influence of personality traits on sexual functioning of schizophrenic and depressive patients, compared to healthy individuals. 300 participants were included in this research. For patients suffering from schizophrenia it was established that the more they are open to experience and the less they are neurotic their sexual drive is stronger. For patients suffering from depression it was established that the more they are open to experience and conscientious and the less they are agreeable their sexual drive is stronger. Furthermore, higher openness is a significant predictor for easier sexual arousal and the more those patients are conscientious and the less they are agreeable easier is for them to achieve orgasms. Personality traits proved to be significant predictors of sexual functioning in schizophrenic and depressive patients, but not in healthy individuals.

Abstract
Alprazolam belongs in the group of anxiolytics, medicaments used for reducing anxiety. As most other drugs, it can cause various adverse events, including hormonal disturbances and imbalance. Prolactin elevation is one such hormonal adverse event that can lead to galactorrhoea, or abnormal milk discharge from the breast and amenorrhoea. In this case report we will present the case of a female patient that developed galactorrhoea while treated with alprazolam, after all physical factors that can also cause these symptoms were excluded.

Abstract
Akathisia is a syndrome characterized by the unpleasant sensation of "inner" restlessness that manifests itself in the inability of sitting still or not moving. Many types of medicaments can cause akathisia as an adverse event of their use and they include: antipsychotics, antidepressants, antiemetics, antihistamines, and psychoactive substances. We will present the case of a 50 year old patient, treated on two occasions for psychotic depression. During the second hospitalization it is possible that antipsychotic treatment combined with an antidepressant caused akathisia or there were symptoms of agitated depression and akathisia present at the same time, which is very difficult to determine in everyday clinical practice. We can conclude that in this case, as in many others, akathisia as a possible adverse effect of psychopharmacs was very hard to identify. Therefore, it is necessary to have akathisia in mind when using certain medicaments, especially when combining several that use the same enzymatic system and consequently raise levels of at least one of them.
