The rs4354668 polymorphism in the SLC1A2 gene for the EAAT2 glutamate transporter is associated with an increased risk of harmful drug use - an exploratory study on a university student population. / Polimorfizm rs4354668 w genie SLC1A2 dla transportera glutaminianu EAAT2 wiazacy sie ze zwiekszonym ryzykiem szkodliwego uzywania narkotyków ­ badanie eksploracyjne na populacji studentów.

OBJECTIVES: Evidence suggests that decreased dopamine secretion in mesocorticolimbic pathways could predispose to increased susceptibility to substance addiction. It has been proposed to define such a phenomenon as the reward deficit syndrome (RDS). Dopaminergic projections of the reward system receive glutaminergic projections from cortex. Research indicates that a reduction in the stimulating glutamatergic transmission on the dopaminergic system could represent an alternative phenotype of RDS. Potential source of this type of abnormality is glutamate reuptake which depends on excitatory amino acid transport proteins (EAAT) function. The most important of them is EAAT2, polymorphisms of which have been linked to several mental disorders. METHODS: We analyzed the genetic and psychometric data of 125 young adults (n = 125) for the effect of the rs4354668 polymorphism of the SLC1A2 gene for EAAT2 on the risky or harmful drug use (RHDU). After exploratory analysis we used logistic regression models to assess the probability of RHDU in individual groups. RESULTS: In the final model T/T variant of rs4354668 was significantly associated with a lower probability of RHDU occurrence compared to G/G variant (OR: 0.021; 95% CI: 0.001 - 0.275; p = 0.009). Other significant predictors of RHDU were smoking status and risky or harmful drinking of alcohol. CONCLUSIONS: The results obtained may indicate a possible relationship of the risk of harmful drug use with variants of the rs4354668 polymorphism of the SLC1A2 gene for EAAT2. Subjects with the T/T variant of this polymorphism appear to be less at risk of developing drug use disorders.

The importance of oxidative biomarkers in diagnosis, treatment, and monitoring schizophrenia patients.

INTRODUCTION: The etiology of schizophrenia (SCZ), an incredibly complex disorder, remains multifaceted. Literature suggests the involvement of oxidative stress (OS) in the pathophysiology of SCZ. OBJECTIVES: Determination of selected OS markers and brain-derived neurotrophic factor (BDNF) in patients with chronic SCZ and those in states predisposing to SCZ-first episode psychosis (FP) and ultra-high risk (UHR). MATERIALS AND METHODS: Determination of OS markers and BDNF levels by spectrophotometric methods and ELISA in 150 individuals (116 patients diagnosed with SCZ or in a predisposed state, divided into four subgroups according to the type of disorder: deficit schizophrenia, non-deficit schizophrenia, FP, UHR). The control group included 34 healthy volunteers. RESULTS: Lower activities of analyzed antioxidant enzymes and GSH and TAC concentrations were found in all individuals in the study group compared to controls (p < 0.001). BDNF concentration was also lower in all groups compared to controls except in the UHR subgroup (p = 0.01). Correlations were observed between BDNF, R-GSSG, GST, GPx activity, and disease duration (p < 0.02). A small effect of smoking on selected OS markers was also noted (rho<0.06, p < 0.03). CONCLUSIONS: OS may play an important role in the pathophysiology of SCZ before developing the complete clinical pattern of the disorder. The redox imbalance manifests itself with such severity in individuals with SCZ and in a state predisposing to the development of this psychiatric disease that natural antioxidant systems become insufficient to compensate against it completely. The discussed OS biomarkers may support the SCZ diagnosis and predict its progression.

Greater methylation of the IL-6 promoter region is associated with decreased integrity of the corpus callosum in schizophrenia.

BACKGROUND: Schizophrenia is associated with chronic subclinical inflammation and decreased integrity of the corpus callosum (CC). Our previous study showed associations between peripheral IL-6 levels and the integrity of the CC. Epigenetic studies show associations between methylation of the genes related to immunological processes and integrity of the CC. AIM: To investigate correlations between methylation status of IL-6 promotor and peripheral IL-6 levels and the integrity of the CC in schizophrenia. MATERIAL AND METHODS: The participants were 29 chronic schizophrenia patients (SCH) and 29 controls. Decreased integrity of the CC was understood as increased mean diffusivity (MD) and/or decreased fractional anisotropy (FA) in diffusion tensor imaging. Peripheral IL-6 concentrations were measured in serum samples and IL-6 promoter methylation status of 6 CpG sites was analyzed in peripheral leukocytes by pyrosequencing. RESULTS: Moderate positive correlations were found between CpG1 methylation and the MD of proximal regions of the CC (CCR1-CCR3) and between CpGmean and MD of CCR1 in SCH. Weaker positive correlations were found for CpGmean with CCR2 and CCR3 and negative correlations were found for CpG1 and FA of CCR3 in SCH. Multivariate regression showed that methylation of CpG1, type of antipsychotic treatment, and their interaction were significant independent predictors of MD of CCR1 in SCH. Methylation of CpG2 was negatively correlated with serum IL-6 in SCH. CONCLUSIONS: The methylation level of the IL-6 promotor region in peripheral leukocytes is associated with the integrity of the CC in schizophrenia and this association may depend on the type of antipsychotic treatment. Further studies are necessary to explain the mechanisms of the observed associations.

Coping styles do not interact with the association between childhood trauma history and the immune-inflammatory phenotype of schizophrenia: Findings from a cross-sectional study.

Adverse childhood experiences (ACEs) are a well-known risk factor of schizophrenia. Moreover, individuals with schizophrenia are likely to use maladaptive stress coping strategies. Although it has been reported that a history of ACEs might be associated with a pro-inflammatory phenotype in patients with schizophrenia, the interacting effect of coping styles on this association has not been tested so far. In the present study, we aimed to investigate the levels of immune-inflammatory markers in patients with schizophrenia and healthy controls (HCs), taking into consideration a history of ACEs and coping strategies. Participants included 119 patients with schizophrenia and 120 HCs. Serum levels of 26 immune-inflammatory markers were determined. A history of any categories of ACEs was significantly more frequent in patients with schizophrenia. Moreover, patients with schizophrenia were significantly more likely to use emotion-focused coping and less likely to use active coping strategies compared to HCs. The levels of interleukin(IL)-6, RANTES, and tumor necrosis factor-α (TNF-α), appeared to be elevated in patients with schizophrenia after adjustment for potential confounding factors in all tested models. Participants reporting a history of any ACEs had significantly higher levels of TNF-α and IL-6. No significant main and interactive effects of active strategies as the predominant coping on immune-inflammatory markers with altered levels in patients with schizophrenia were found. Findings from the present study indicate that ACEs are associated with elevated TNF-α and IL-6 levels regardless of schizophrenia diagnosis and predominant coping styles.

Burnout in healthcare - the Emperor's New Clothes.

Burnout is common among physicians; it severely alters their health and has a negative impact on functioning of healthcare systems. Hypertension, increased cortisol levels, maladaptive behaviors with negative social consequences, and suboptimal quality of care have been associated with healthcare providers' burnout. As the number of patients with cancers, psychiatric and neurodegenerative disorders will rise, we need new solutions to maintain physicians' health and, therefore, quality of care. Coping strategies before the COVID-19 pandemic seem ineffective in scaling all the deficits of the global healthcare systems. Examples of new initiatives include new collaborative projects, such as COH-FIT (The Collaborative Outcomes study on Health and Functioning during Infection Times - https://www.coh-fit.com), which aims to collect global data and understand the impact of the COVID-19 pandemic on physical and mental health in order to identify various coping strategies for patients and healthcare workers during infection times, or MEMO (Minimizing Error, Maximizing Outcome), funded by the Agency of Healthcare Research and Quality (AHRQ). Others: i) Rome Foundation GastroPsych undertake efforts dedicated to the science and practice of psychogastroenterology, a burgeoning field with roots in behavioral intervention, cognitive science and experimental psychology focused on fostering the professional growth and collaboration of those engaged in medical practices, or ii) World Gastroenterology Organisation (WGO), Train The Trainers (TTT) program including a new topic of the impact of burnout on career longevity in order to foster strategies for staying healthy and increasing career satisfaction. There is a need for continuous development of digital technologies (e.g. training simulators, telemedicine, robots and artificial intelligence). Their implementation into medical practice is inevitable. Now more than ever, there is a need for a new spirit in healthcare. Together with others in the field, we believe this article is a desperate call for maximizing the use of novel technologies supported by collaborative interactions among healthcare providers and medical professionals of diverse medical fields.

Management of nicotine dependence in patients with psychiatric disorders - recommendations of the Polish Psychiatric Association - part I. / Postepowanie w uzaleznieniu od nikotyny u pacjentów z zaburzeniami psychicznymi ­ zalecenia Polskiego Towarzystwa Psychiatrycznego ­ czesc I.

Smoking and nicotine dependence are still one of the main reasons for a number of serious and life-shortening somatic diseases. At the same time, they are more prevalent in mentally ill individuals than in the general population. This work, which constitutes the first part of recommendations of the Polish Psychiatric Association, presents the scale of the phenomenon in the general population and among people with psychiatric disorders, diagnostic criteria of nicotine dependence and nicotine withdrawal. It discusses the impact of smoking and exposure to cigarette smoke on the development and course of psychiatric disorders as well as on the treatment of psychiatric disorders, including interactions between nicotine and psychotropic medications. Many psychiatric patients can reduce smoking or achieve complete abstinence if they are offered adequate motivation and therapeutic support. Contrary to popular belief, smoking cessation and nicotine dependence treatment do not negatively affect the symptoms of psychiatric disorders; patients' mental conditions can improve following smoking cessation therapy. The best results in terms of maintaining abstinence are achieved with a treatment approach that combines pharmacotherapy with psychotherapeutic intervention integrated into routine psychiatric care.

Management of nicotine dependence in patients with psychiatric disorders - recommendations of the Polish Psychiatric Association - part II. / Postepowanie w uzaleznieniu od nikotyny u pacjentów z zaburzeniami psychicznymi ­ zalecenia Polskiego Towarzystwa Psychiatrycznego ­ czesc II.

The development of treatment methods for nicotine dependence has progressed slowly because people with psychiatric disorders are usually excluded from participating in clinical trials. There are several therapeutic options to support smoking cessation, including psychological and pharmacological interventions, which should be offered to smokers with mental disorders. The first step in helping tobacco smokers and nicotine-dependent individuals is the assessment of smoking intensity and confirmation of nicotine dependence. Currently, we have several methods of treating nicotine dependence - starting from education and psychotherapy, through pharmacotherapy and replacement therapy, and ending up with obtaining gradual progress with the application of harm reduction. Pharmacological treatment options include nicotine replacement therapy, varenicline or bupropion. The effectiveness of such interventions can be improved by providing anti-smoking therapy under psychiatric treatment and promoting harm reduction as an acceptable initial therapeutic goal. The harm reduction strategy is an approach that should be taken into account individually, particularly in the case of individuals unable to stop smoking, patients with limited insight into their illness, patients experiencing an exacerbation of their illness and persistently uncooperative patients. In this paper, recommendations of the Polish Psychiatric Association on the diagnostics and different treatment methods for nicotine dependence in patients with psychiatric disorders are presented.

The deficit subtype of schizophrenia is associated with a pro-inflammatory phenotype but not with altered levels of zonulin: Findings from a case-control study.

There is evidence that subclinical inflammation and increased gut permeability might be involved in the pathophysiology of schizophrenia. Less is known about these phenomena in patients with the deficit subtype of schizophrenia (D-SCZ) characterized by primary and enduring negative symptoms. Therefore, in the present study we aimed to compare the levels of zonulin (the marker of gut permeability) and immune-inflammatory markers in patients with D-SCZ, those with non-deficit schizophrenia (ND-SCZ) and healthy controls (HCs). A total of 119 outpatients with schizophrenia and 120 HCs were enrolled. The levels of 26 immune-inflammatory markers and zonulin were determined in serum samples. The following between-group differences were significant after adjustment for multiple testing and the effects of potential confounding factors: 1) higher levels of interleukin(IL)- 1ß and C-reactive protein (CRP) in patients with D-SCZ compared to those with ND-SCZ and HCs; 2) higher levels of tumor necrosis factor-α and RANTES in both groups of patients with schizophrenia compared to HCs and 3) higher levels of IL-17 in patients with D-SCZ compared to HCs. No significant between-group differences in zonulin levels were found. Higher levels of IL-1ß and CRP were associated with worse performance of attention after adjustment for age, education and chlorpromazine equivalents. Also, higher levels of IL-1ß were correlated with greater severity of negative symptoms after adjustment for potential confounding factors. In conclusion, individuals with D-SCZ are more likely to show subclinical inflammation. However, findings from the present study do not support the hypothesis that this phenomenon is secondary to increased gut permeability.

Complement Activation Products in Patients with Chronic Schizophrenia.

Evidence suggests a role of the immune system in the pathogenesis of a number of mental conditions, including schizophrenia (SCH). In terms of physiology, aside from its crucial protective function, the complement cascade (CC) is a critical element of the regeneration processes, including neurogenesis. Few studies have attempted to define the function of the CC components in SCH. To shed more light on this topic, we compared the levels of complement activation products (CAP) (C3a, C5a and C5b-9) in the peripheral blood of 62 patients with chronic SCH and disease duration of ≥ 10 years with 25 healthy controls matched for age, sex, BMI and smoking status. Concentrations of all the investigated CAP were elevated in SCH patients. However, after controlling for potential confounding factors, significant correlations were observed between SCH and C3a (M = 724.98 ng/mL) and C5a (M = 6.06 ng/mL) levels. In addition, multivariate logistic regression showed that C3a and C5b-9 were significant predictors of SCH. There were no significant correlations between any CAP and SCH symptom severity or general psychopathology in SCH patients. However, two significant links emerged between C3a and C5b-9 and global functioning. Increased levels of both complement activation products in the patient group as compared to healthy controls raise questions concerning the role of the CC in the etiology of SCH and further demonstrate dysregulation of the immune system in SCH patients.

Risk factors of deficit and non-deficit schizophrenia: Results from a cross-sectional study.

AIM: It has been observed that deficit and non-deficit schizophrenia (SCZ-D and SCZ-ND) might be characterized by different risk factors. Therefore, the present study aimed to assess as to whether previously reported risk factors of schizophrenia are specifically associated with SCZ-D and SCZ-ND. METHOD: This study was based on a cohort of 118 stable outpatients with schizophrenia. A diagnosis of SCZ-D was established using the Schedule for the Deficit Syndrome (SDS). Risk factors were recorded using structured interview, the Operational Criteria for Psychotic Illness (OPCRIT) checklist and the Traumatic Experience Checklist (TEC). The following risk factors were explored: male sex, a history of schizophrenia in first-degree relatives, seasonality of birth, birth weight <3000g, delivery by cesarean section, a history of childhood trauma (emotional abuse, emotional neglect, physical abuse and sexual abuse) as well as substance abuse (other than nicotine) and cigarette smoking at psychosis onset. RESULTS: Individuals with SCZ-D were more likely to be males as well as reported higher rates of birth weight <3000g and any categories of childhood trauma. In turn, substance abuse (other than nicotine) at psychosis onset was significantly more frequent in patients with SCZ-ND. Binary logistic regression, controlling for multiple comparisons, revealed similar findings, except for the association with any categories of childhood trauma that appeared to be not significant. CONCLUSION: Our findings partially replicate differential patterns of risk factors for SCZ-D (male sex and birth weight <3000g) and SCZ-ND (substance abuse at psychosis onset), likely attributable to the effects of timing of exposure.

Peripheral blood inflammatory markers in patients with attention deficit/hyperactivity disorder (ADHD): A systematic review and meta-analysis.

It has been observed that subclinical inflammation might be involved in the pathophysiology of attention deficit/hyperactivity disorder (ADHD). However, studies investigating peripheral blood levels of immune-inflammatory markers have provided mixed findings. We performed a systematic review and meta-analysis of studies comparing unstimulated serum or plasma levels of C-reactive protein (CRP) and cytokines in subjects with ADHD and healthy controls (the PROSPERO registration number: CRD 42021276869). Online searches covered the publication period until 30th Sep 2021 and random-effects meta-analyses were carried out. Out of 1844 publication records identified, 10 studies were included. The levels of interleukin (IL)-6 were significantly higher in studies of participants up to the age of 18 years (k = 10, g = 0.70, 95%CI: 0.10-1.30, p = 0.023) and after including those above the age of 18 years (k = 10, g = 0.71, 95%CI: 0.12-1.31, p = 0.019). In turn, the levels of tumor necrosis factor-α (TNF-α) were significantly lower in subjects with ADHD compared to healthy controls (k = 7, g = -0.16, 95%CI: -0.30 - -0.03, p = 0.020). Individual studies had a high contribution to the overall effect, since the overall effect was no longer significant after removing single studies. No significant differences were found with respect to the levels of CRP, IL-1ß, IL-10 and interferon-γ. The present findings indicate that individuals with ADHD tend to show elevated levels of IL-6 and reduced levels of TNF-α. Larger and longitudinal studies recording potential confounding factors and comorbid psychopathology are needed to confirm our findings.

Psychopathology and Stem Cell Mobilization in Ultra-High Risk of Psychosis and First-Episode Psychosis Patients.

Although regenerative and inflammatory processes are involved in the etiopathogenesis of many psychiatric disorders, their roles are poorly understood. We investigate the potential role of stem cells (SC) and factors influencing the trafficking thereof, such as complement cascade (CC) components, phospholipid substrates, and chemokines, in the etiology of schizophrenia. We measured sphingosine-1-phosphate (S1P), stromal-derived factor 1 (SDF-1), and CC cleavage fragments (C3a, C5a, and C5b-C9; also known as the membrane attack complex) in the peripheral blood of 49 unrelated patients: 9 patients with ultra-high risk of psychosis (UHR), 22 patients with first-episode psychosis (FEP), and 18 healthy controls (HC). When compared with the HC group, the UHR and FEP groups had higher levels of C3a. We found no significant differences in hematopoietic SC, very small embryonic-like stem cell (VSEL), C5a, S1P, or SDF-1 levels in the UHR and FEP groups. However, among FEP patients, there was a significant positive correlation between VSELs (CD133+) and negative symptoms. These preliminary findings support the role of the immune system and regenerative processes in the etiology of schizophrenia. To establish the relevance of SC and other factors affecting the trafficking thereof as potential biomarkers of schizophrenia, more studies on larger groups of individuals from across the disease spectrum are needed.

Serum inflammatory markers and their associations with white matter integrity of the corpus callosum in schizophrenia patients and healthy controls.

Schizophrenia is associated with disrupted integrity of white matter microstructure of a variety of brain regions, especially the corpus callosum (CC). Chronic subclinical inflammation is considered to be one of the factors involved in the pathogenesis of this disease, and increased levels of peripheral inflammatory markers are often observed in schizophrenia patients. Therefore, we decided to investigate whether the integrity of the corpus callosum is correlated with levels of these markers. A total of 50 patients with stable chronic schizophrenia (SCH) and 30 controls (CON) were enrolled in the study. All participants underwent psychiatric evaluation, neuroimaging, and blood sampling including the measurement of serum concentrations of interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL - 10), tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), and C-reactive protein (CRP). Additional potentially related factors, such as age, gender, BMI, smoking, disease duration, and treatment were included in the analysis. Significantly higher IL-6 and IFN-γ levels were observed in SCH compared to CON. In SCH, IFN-γ was positively correlated with mean diffusivity of region 2 of the CC. In CON, IL-6 was inversely correlated with fractional anisotropy of region 1 of the CC. These results support the potential influence of peripheral inflammatory markers on the integrity of the CC in schizophrenia, but require verification in longitudinal studies.

Immune-inflammatory markers and psychosis risk: A systematic review and meta-analysis.

Subclinical inflammation has been associated with psychosis; however, it remains unknown whether this phenomenon appears also in the premorbid phase. Therefore, we performed a systematic review and meta-analysis of studies comparing peripheral blood levels of C-reactive protein (CRP) and cytokines between individuals at risk of psychosis and controls. Moreover, we tested the hypothesis that the levels of these markers may be different in high-risk converters versus non-converters. Two independent reviewers searched electronic databases until Dec 16th, 2020. After reviewing publication records, 16 studies (548 high-risk individuals and 559 controls) were included. Random-effects meta-analyses with Hedges' g as the effect size estimate were performed. Individuals at clinical risk of psychosis had significantly higher levels of interleukin-6 (IL-6) compared to controls (g = 0.33, 95%CI: 0.06-0.60, p = 0.018). Heterogeneity was not significant in this subgroup analysis. Changes in the levels of IL-6 in subjects at familial risk of psychosis were not significant (g = 0.04, 95%CI: -0.24 to 0.31, p = 0.798). The use of antidepressants was associated with significantly higher levels of IL-6 in high-risk individuals (Beta = 1.56, 95%CI: 0.60-2.53, p = 0.001). No significant differences in the levels of immune-inflammatory markers were found between high-risk converters and non-converters. Our findings suggest that individuals at clinical risk of psychosis show subclinical inflammation in terms of elevated IL-6 levels. This phenomenon might be related to the use of antidepressants. The present meta-analysis does not support the usefulness of single immune-inflammatory markers in predicting transition to psychosis.

Cortisol and dehydroepiandrosterone sulfate in patients with schizophrenia spectrum disorders with respect to cognitive performance.

Prolonged activation of the hypothalamic-pituitary-adrenal (HPA) axis associated with hypercortisolemia may lead to impairments of cognition in various populations. Dehydroepiandrosterone sulfate (DHEA-S) can protect the hippocampus from the detrimental effects of cortisol. However, this phenomenon has not been widely investigated in patients with schizophrenia spectrum disorders (SSD). Therefore, in this study, we aimed to assess the levels of cortisol, DHEA-S and cortisol/DHEA-S ratio in patients with SSD and healthy controls with respect to cognitive performance. Participants were 85 patients with SSD and 56 healthy controls, matched for age, sex and body-mass index. Cognitive performance was examined using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The levels of hormones were measured in fasting serum samples. The levels of morning cortisol were significantly higher in patients with SSD compared to healthy controls, even after co-varying for potential confounding factors. There were no significant between-group differences in the levels of DHEA-S and cortisol/DHEA-S ratio. Higher levels of cortisol and greater cortisol/DHEA-S ratio were related to significantly lower RBANS scores of delayed memory in patients with SSD, but not in healthy controls after controlling for the effects of age, sex, BMI, the number of education years, cigarette smoking status and the dosage of antipsychotics. Our findings imply that elevated cortisol levels may contribute to impairments of memory processes in patients with SSD. However, longitudinal studies are needed to confirm causal associations.

Real-life anti-smoking practices among Polish neurologists.

Purpose: The aim of the present study was to assess attitudes of Polish neurologists towards cigarette smoking and their real-life anti-smoking practices. Methods: A study questionnaire was constructed, and distributed among Polish neurologists (n = 101; 73% females). More than two thirds (70%) of the study group worked in in-patient neurological wards with separate stroke units. Results: Seventy five percent of the study group documented the smoking status of their patients in medical files. Two thirds of the study group collected data on patient's cigarette smoking during each visit. Only 54% and 22% of study participants routinely assessed the severity of tobacco dependence and diagnosed tobacco dependence according to the ICD-10 criteria, respectively. Two thirds of physicians declared routinely using any anti-smoking intervention, but only 12% used the recommended 5'A (Ask, Advice, Assess, Assist, Arrange) model of behavioral intervention and only 11% introduced Evidence Based Medicine (EBM)-supported pharmacotherapy. The vast majority of study participants (80%) did not try to increase their professional skills in anti-smoking interventions. Conclusions: Real-life anti-smoking practices among Polish neurologists are generally unsatisfactory and do not follow EBM-based guidelines. The low percentage of neurologists who diagnose and treat nicotine dependence may negatively impact the efficacy of secondary stroke prevention in Poland.

Efficacy and safety of the Calistar and Elevate anterior vaginal mesh procedures.

OBJECTIVES: The pelvic organ prolapse (POP) surgery with implantation of anterior transvaginal mesh (e.g. Elevate or Calistar) may provide objective and subjective improvement as compared to traditional POP repair without mesh. Given differences between the Elevate and the Calistar mesh and their different placement methods, some variation inlong-term clinical outcomes of these anterior vaginal mesh procedures can be expected. STUDY DESIGN: The purpose of the study was to compare the 18-month operative success in patients who had undergone anterior POP surgery with either the Calistar (n = 54) or Elevate mesh (n = 50). RESULTS: There were no between-group differences in objective measures of operative efficacy, including POP-Q anterior stage 0 or I (94% for Calistar, 92% for Elevate) and "no descent beyond the hymen" (98% for Calistar, 94% for Elevate). The proportion of patients with subjective measure of operative efficacy (no vaginal bulge symptoms) did not differ between the groups (91% for Calistar, 78% for Elevate). There were no between-group differences in the proportion of women suffering from vaginal exposure, de novo stress urinary incontinence (SUI), de novo overactive bladder (OAB) symptoms, pelvic floor pain or dyspareunia. The operative cure of OAB symptoms was similar in the groups. The proportion of patients with the operative cure of SUI symptoms was significantly higher in the Calistar as compared to the Elevate group. CONCLUSIONS: The results suggestthat the Calistar system offers similar efficacy in the treatment of anterior and both anterior and apical POP as compared to the Elevate. The use of anterior Calistar is associated with some additional benefits, i.e. SUI treatment in patients with concomitant anterior and both anterior and apical POP and SUI symptoms.

ATP-Nlrp3 Inflammasome-Complement Cascade Axis in Sterile Brain Inflammation in Psychiatric Patients and its Impact on Stem Cell Trafficking.

Recent evidence indicates that the occurrence of psychiatric disorders in patients is linked to a local "sterile" inflammation of brain or due to a systemic inflammation process that affects the central nervous system. This is supported by the observation that in peripheral blood of psychotic patients are detectable several mediators and markers of inflammation as well as clinical data on correlations between systemic chronic inflammatory processes and psychiatric disorders. This may explain why some reported anti-inflammatory treatment strategies have beneficial effects on ameliorating psychotic events. In this review we will present a concept that aberrant purinergic signaling and increases in extracellular level of adenosine triphosphate (ATP) in the brain parenchyma may lead to activation of Nlrp3 inflammasome in microglia cells and as a consequence microglia released danger associated molecular pattern (DAMP) proteins activate complement cascade (ComC) in mannan binding lectin (MBL) - dependent manner. Activation of ATP-Nlrp3 inflammasome-ComC axis may also orchestrate trafficking of stem cells released from bone marrow into peripheral blood observed in psychotic patients. Based on this, the ATP-Nlrp3 inflammasome-ComC axis may become a target for new therapeutic approaches, which justifies the development and clinical application of efficient anti-inflammatory treatment strategies targeting this axis in psychiatry.

Metabolic risk reduction in patients with schizophrenia treated with antipsychotics: recommendations of the Polish Psychiatric Association. / Redukcja ryzyka metabolicznego u chorych na schizofrenie przyjmujacych leki przeciwpsychotyczne ­ zalecenia Polskiego Towarzystwa Psychiatrycznego.

Patients with schizophrenia are susceptible to physical illnesses, which reduces their life expectancy by an average of 20 years compared with the general population. The most common physical illnesses amongst patients with schizophrenia are metabolic disorders and cardiovascular diseases. The aim of this paper is to present recommendations on metabolic risk reduction in patients with schizophrenia treated with antipsychotics, accepted as a position statement of the Polish Psychiatric Association for use in the management of persons suffering from schizophrenia in Poland. A routine assessment of metabolic risk is recommended for the early detection of metabolic disorders and to monitor the safety of the antipsychotic treatment. It includes: medical history, physical examination, laboratory tests. Each patient should undergo this assessment before the initiation of treatment, after 6 and 12 weeks of treatment, and at least once a year thereafter. In men and women suffering from schizophrenia who are over the age of 40 and 50 years, respectively, a cardiovascular risk assessment using the SCORE charts is also recommended. (1) Antipsychotics with a low potential to cause metabolic disorders should be preferred and administered at the appropriate dose in order to reduce metabolic risk. (2) If other agents found to cause metabolic disorders are used, the treatment should be modified by augmentation or by switching to another antipsychotic with a lower potential to cause metabolic disorders. (3) Consultation by an internal medicine specialist and medical treatment should be recommended. (4) Patients should be assisted in developing healthy eating habits, encouraged to pursue regular physical activity and (5) to quit smoking, drinking alcohol and using psychoactive substances.

Assessment of the Association Between Cigarette Smoking and Cognitive Performance in Patients With Schizophrenia-Spectrum Disorders: A Case-Control Study.

The prevalence of cigarette smoking is significantly higher in patients with schizophrenia compared to the general population. Schizophrenia is also characterized by cognitive impairments that can be detected in the premorbid phase of illness. However, studies addressing the association between cigarette smoking and cognition in patients with psychosis have provided mixed findings. Therefore, the aim of this study was to assess the relationship between tobacco smoking and cognitive performance in patients with schizophrenia. In this case-control study, we recruited 67 inpatients with schizophrenia (34 cigarette smokers) and 62 healthy controls (30 cigarette smokers) at two clinical sites (Wroclaw and Szczecin, Poland). Cognitive performance was examined using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Smoking dependence was determined using the Fagerström Test for Nicotine Dependence (FTND) and the pack-year index. Results show that, after adjustment for potential confounders, smokers with schizophrenia presented significantly lower scores on delayed memory tests compared to non-smokers with schizophrenia (F = 11.07, p = 0.002). In healthy controls, after adjustment for age, sex, and education level, smokers had significantly lower scores in immediate memory (47.1 ± 6.4 vs. 52.0 ± 4.0, F = 11.64, p = 0.001), visuospatial/constructional functions (34.8 ± 3.8 vs. 37.7 ± 1.8, F = 12.86, p = 0.001) and global cognition (177.0 ± 15.7 vs. 191.2 ± 14.0, F = 12.63, p = 0.001) compared to non-smokers. There were no significant correlations between FTND scores or pack-year index and cognitive performance neither in patient nor control group. Our results show that cigarette smoking is related to worse delayed memory performance in schizophrenia patients as well as deficits of immediate memory, visuospatial/constructional functions, and global cognition in controls. Longitudinal studies are required to establish causal interference between smoking and cognition in patients with schizophrenia.
