Premenstrual syndrome: new insights into etiology and review of treatment methods.

Premenstrual syndrome (PMS) is a common disorder affecting women of reproductive age, with an estimated global prevalence of 47.8%, with severe symptoms occurring in 3-8%, significantly affecting daily functioning. GABA conductance and changes in neurosteroid levels, particularly allopregnanolone, are suspected to play a substantial role in the disorder's etiology. In this paper, we provide an overview of recent reports on the etiology and recognized therapeutic approaches, encompassing both pharmacological and non-pharmacological interventions. Our examination includes studies on SSRIs, hormonal agents, neurosteroids, supplementation, and therapeutic roles. We aim to determine the most favorable treatment regimen by comparing medication effects and alternative methods. The treatment of PMS is crucial for enhancing the quality of life for affected women. Medications used in PMS treatment should be individually selected to achieve the best therapeutic effect, considering the clinical situation of the patients.

Oxidative stress parameters in women and men with suicidal thoughts and following a suicide attempt.

Background: This study aimed to evaluate oxidative stress parameters in individuals with depression and schizophrenia, considering gender differences, and manifesting suicidal behavior, encompassing thoughts without a tendency to be realized, thoughts with a tendency to be realized, and suicide attempts. Methods: From among the patients from Department of Psychiatry 120 individuals were selected who met the inclusion criteria and did not meet the exclusion criteria for the study. In the initial phase of the project, patients eligible for the study underwent the M.I.N.I 7.0.2 questionnaire (Mini International Neuropsychiatric Interview). Subsequently, in the second phase of the research, venous blood samples were collected from the patients for the purpose of conducting biochemical assessments, focusing on oxidative stress parameters. Results: The obtained results suggest that redox biomarkers, namely TOS (total oxidation state) and OSI (TOS/TAC ratio), in the blood plasma of women increase in tandem with the severity of suicidal behavior. No notable alterations in SOD (Cu-Zn-superoxide dismutase), GPx (glutathione peroxidase), and GSH (reduced glutathione) concentrations and activity were noted between groups exhibiting suicidal behavior. The observed variations in the concentrations and activity of antioxidant parameters were significant solely in comparison to the control group. Conclusions: Redox biomarkers TOS and OSI could prove valuable in diagnosing women at a genuine risk of committing suicide. On the other hand, antioxidant parameters - SOD, GPx, and GSH may be instrumental in identifying patients with suicidal behaviors, without specifying their intensity.

Between Dysbiosis, Maternal Immune Activation and Autism: Is There a Common Pathway?

Autism spectrum disorder (ASD) is a neuropsychiatric condition characterized by impaired social interactions and repetitive stereotyped behaviors. Growing evidence highlights an important role of the gut-brain-microbiome axis in the pathogenesis of ASD. Research indicates an abnormal composition of the gut microbiome and the potential involvement of bacterial molecules in neuroinflammation and brain development disruptions. Concurrently, attention is directed towards the role of short-chain fatty acids (SCFAs) and impaired intestinal tightness. This comprehensive review emphasizes the potential impact of maternal gut microbiota changes on the development of autism in children, especially considering maternal immune activation (MIA). The following paper evaluates the impact of the birth route on the colonization of the child with bacteria in the first weeks of life. Furthermore, it explores the role of pro-inflammatory cytokines, such as IL-6 and IL-17a and mother's obesity as potentially environmental factors of ASD. The purpose of this review is to advance our understanding of ASD pathogenesis, while also searching for the positive implications of the latest therapies, such as probiotics, prebiotics or fecal microbiota transplantation, targeting the gut microbiota and reducing inflammation. This review aims to provide valuable insights that could instruct future studies and treatments for individuals affected by ASD.

Impact of Pregnancy on Self-Efficacy and Personal Competence in the Context of Risk of Depression, Mental Health Status, and Satisfaction with Life.

For many women, pregnancy and childbirth are often accompanied by strong emotions related to fear, stress, and anxiety about the health of the woman and her child. This study aimed to assess the effect of pregnancy on the risk of depression, mental health status, and satisfaction with life in women in Poland, Greece, Turkey, Belarus, and Russia. MATERIAL AND METHODS: A cross-sectional comparative study was conducted among 2017 women surveyed, including 584 pregnant women, 528 postpartum women, and 906 women who had never been pregnant (the comparative group) from Poland, Greece, Turkey, Belarus, and Russia. The sample selection was purposive. Surveys were collected between November 2021 and December 2022. The study used the Beck Depression Inventory (BDI) Scale, the Satisfaction with Life Scale (SWLS), the Edinburgh Postpartum Depression Scale (EPDS), the GHQ-28 (General Health Questionnaire), the Schwarzer Generalized Self-Efficacy Scale (GSES), and the KompOs Personal Competence Scale. RESULTS: A significantly lower risk of depression was observed in postpartum women in Poland and amongst pregnant women in Turkey. Pregnant women in Turkey (28.9 points) presented the highest satisfaction with life, while the lowest satisfaction was found amongst pregnant women in Poland and Greece (25.2 and 25.1 points, respectively). In Poland and Belarus, a higher risk of depression was noticed in women who had undergone an artificial abortion. In Turkey, a positive correlation was found in pregnant women concerning the number of children they had with a measure of depression and a negative correlation with life satisfaction. In Greece, non-pregnant women showed no correlation between mental status and scores on the GSES. Scores on satisfaction with SWLS were positively correlated with a sense of power, and the strength of the correlation was similar to results on the BDI and GHQ measures. Postpartum depression, according to the EPDS, was also the most severe in Turkish women. CONCLUSIONS: The highest risk of depression was shown in the control group and amongst pregnant and postpartum women in Turkey and Greece, and the lowest such risk was in Poland. Pregnant and postpartum women showed by far the highest satisfaction with life in Turkey and the lowest in women from Greece. The risk of depression, the level of satisfaction with life, and the mental health of pregnant women were not influenced by the type of last delivery. However, the duration of the last delivery influenced the group from Belarus, and having children affected the mental health of women in the group from Turkey.

Zuranolone - synthetic neurosteroid in treatment of mental disorders: narrative review.

With each passing year, the number of people suffering from mental disorders grows at a disturbing speed. Neuroactive steroids are a new promising group of drugs with the potential for use in many diseases like postpartum depression, postnatal psychosis, major depression, insomnia, bipolar disorder, and Parkinson's tremor, due to their ability to modulate the activity of GABAA receptor. Neurosteroids are progesterone metabolites that are synthesized from cholesterol or steroid hormones in various brain regions. They regulate neuronal development, regeneration, and neurotransmission. They are implicated in mood disorders, anxiety disorders, schizophrenia, PTSD, and impulsive aggression. Neurosteroids have been studied for their potential to prevent or treat neurodegenerative diseases such as Alzheimer's disease and HIV-associated dementia. They can promote neurogenesis, neuronal survival, myelination, and memory function. They can also affect the growth and sensitivity of hormone-dependent brain tumors such as gliomas. Zuranolone, a newly registered neurosteroid drug has shown huge flexibility in both clinical and ambulatory treatment thanks to its pharmacokinetic traits, especially the possibility for oral administration, unlike its predecessor Brexanolone. Zuranolone is a synthetic positive allosteric modulator of the GABAA receptor that can be taken orally. The review aims to summarize the current knowledge on zuranolone as a novel neurosteroid drug for various mental disorders, especially for postpartum mental disorders for which this drug was meant originally. It covers studies indexed in the PubMed, Scopus, and Web of Science databases published since 2017. Keywords used in the search, as well as inclusion and exclusion criteria, are given in the aims and methodology section. The review explains the evidence for the role of neurosteroids, especially allopregnanolone, in the pathophysiology and treatment of postpartum depression. It discusses the mechanisms of neurosteroid action, the changes in neurosteroid levels during pregnancy and postpartum, and the clinical trials of brexanolone and zuranolone, two synthetic analogs of allopregnanolone, for postpartum depression. It provides an overview of the biosynthesis and metabolism of neurosteroids in the central and peripheral nervous system. Furthermore, it explains the different sources and pathways of neurosteroid production and the factors that influence their synthesis and regulation, such as stress, hormones, drugs, and genetic variations. The review also explores the potential relevance of neurosteroids for other psychiatric disorders, such as major depression, bipolar disorder, post-traumatic stress disorder (PTSD), schizophrenia, and premenstrual dysphoric disorder. Finally, it highlights the associations between neurosteroid levels and symptom severity and the effects of neurosteroid modulation on mood, cognition, and neuroplasticity.

The Effect of Antidepressant Treatment on Neurocognitive Functions, Redox and Inflammatory Parameters in the Context of COVID-19.

Inflammation is an important component of the etiopathology of depression that uses oxidative and nitrosative stress (O&NS) and elevated inflammatory markers. SARS-CoV-2 infection is also associated with abnormal inflammatory processes, which may impair effective treatment of depression in COVID-19 survivors. In the presented study, thirty-three hospitalized patients with major depressive disorder (MDD) were started on antidepressant treatment, and twenty-one were re-evaluated after 4-6 weeks. The control group consisted of thirty healthy volunteers. All participants underwent neuropsychiatric evaluation, biochemical blood and urine analyses. The results of the research demonstrated positive correlations of the Hamilton Depression Rating Scale (HAM-D) scores with serum catalase (CAT) and urinary S-Nitrosothiols levels, and the Beck Depression Inventory (BDI) scores with serum reduced glutathione (GSH) and superoxide dismutase (SOD) levels. Depressed patients with a history of COVID-19 prior to the treatment had higher urinary nitric oxide (NO) levels and lower serum glutathione peroxidase (GPx) levels. In the control group, COVID-19 survivors had higher levels of urinary N-formylkynurenine (NFK). Our results suggest that the antidepressant treatment has a modulating effect on O&NS, reduces depressive symptoms and improves cognitive functions The present study does not indicate that clinical response to antidepressant treatment is associated with COVID-19 history and baseline SARS-CoV-2 antibody levels. Nevertheless, further research in this area is needed to systematize antidepressant treatment in COVID-19 survivors.

Health behaviors and problems in Polish homeless men.

Introduction: Homelessness is considered to be a global problem, independent of the material situation of a given country and occurring in most societies around the world. Aim of the study: Assessment of the preferred health behaviors of homeless people. Materials and methods: The study covered 153 men who are homeless and 312 men who are not homeless. The original questionnaire of homeless, and validated the Satisfaction with Life Scale (SWLS), the Health Behavior Inventory (HBI), the General Self-Efficacy Scale (GSES) and the Multidimensional Health Locus of Control (MHLC) Scale were used. The research covered fully completed questionnaires from 153 homeless men staying in Bialystok and Gdansk homelss centers. Results: On average, the homeless men assessed their health at 6.0 ± 2.7 points, and the non-homeless at 7.8 ± 2.2 points (p < 0.001). Significant differences were found between people experiencing a homelessness crisis and the control group in selected aspects concerning the everyday life hygiene of the respondents, health self-assessment, declarations of visits to a specialist and carrying out check-ups, level of satisfaction with life, coping with difficult situations, preferred pro-health behaviors and dimensions of health control. In the used scales, SWLS, HBI, GES, and MHCL, the majority of homeless men obtained average scores. They were rather dissatisfied with their lives, with a low level of effectiveness in coping with difficult situations and obstacles, a low level of health behaviors, and in the scope of health, control increasing the impact of chance. Conclusion: The level of the presented health behaviors showed statistically significant diversification with all dimensions of the health locus of control, and its internal dimension with age, homelessness phase, the respondents' criminal history, being under constant medical care, and self-assessment of health.

Biomarkers of Postpartum Depression: A Narrative Review.

Postpartum depression (PPD) is a disorder that impairs the formation of the relationship between mother and child, and reduces the quality of life for affected women to a functionally significant degree. Studying markers associated with PPD can help in early detection, prevention, or monitoring treatment. The purpose of this paper is to review biomarkers linked to PPD and to present selected theories on the pathogenesis of the disease based on data from biomarker studies. The complex etiology of the disorder reduces the specificity and sensitivity of markers, but they remain a valuable source of information to help clinicians. The biggest challenge of the future will be to translate high-tech methods for detecting markers associated with postpartum depression into more readily available and less costly ones. Population-based studies are needed to test the utility of potential PPD markers.

The usefulness of a complete blood count in the prediction of the first episode of schizophrenia diagnosis and its relationship with oxidative stress.

A complete blood count (CBC) is a routinely performed blood examination. Only a few studies assess the relationship between CBC and oxidative stress (OS) in schizophrenia (SZ). The aim of the study was to assess the utility of CBC in the prediction of SZ diagnosis, and the relationship between CBC and OS. The study included: 47 individuals with the first episode of psychosis (26 drug-naive: FEP-nt; 21 patients under antipsychotic treatment: FEP-t) and 30 healthy persons (control group, HC). CBC and oxidative stress-related parameters were assessed in blood samples. The FEP group had higher levels of WBC, MCHC, NEU, MONO, EOZ, BASO, and %EOZ compared to HC (p<0.05). Various relationships between OS and CBC were found, and this connection was significantly different between healthy individuals and patients. The most promising C&RT model for discriminating FEP from HC was combining monocytes, eosinophils, and neutrophils (accuracy: 77%, 95%CI = 0.67-0.87). The analysis singled out WBC and HT (accuracy: 74%, 95%CI = 0.64-0.90) as the most promising to distinguish FEP-nt from HC; WBC and %Neu to allocate to FEP-t or HC group (accuracy: 87%, 95%CI = 0.64-0.90); RDW-SD and LYMPH (accuracy: 86%, 95% CI = 0.75-97) for distinguishing FEP-nt from FEP-t. CBC could be a promising, cheap tool to determine abnormalities related to schizophrenia. However, more studies with larger sample sizes are required.

The association between plasma N-terminal pro-brain natriuretic peptide concentration and metabolic disturbances in women with depressive symptoms.

BACKGROUND: The relationship between brain natriuretic peptides and depression was studied in patients with cardiovascular diseases (CVD), but the data in people without CVD are limited. Metabolic disturbances can be associated with natriuretic peptides' levels. The study aimed to assess serum N-terminal pro-brain natriuretic peptide (NT-proBNP) level in women with depressive symptoms and its relationship with metabolic disturbances. METHODS: The analysis included 347 women (20-60 years old) from Bialystok PLUS cohort study: 98 with depressive symptoms and 249 controls. Clinical examination, oral glucose tolerance test (OGTT) and assessment of lipid, sex hormone binding globulin (SHBG) and NT-proBNP concentrations in the blood were performed. The participants completed Beck Depression Inventory questionnaire. RESULTS: Metabolic syndrome was more frequent in the group of women with depressive symptoms compared to women without depressive symptoms. Women with depressive symptoms had lower NT-proBNP level than the control group - 45.88 (27.80-67.04) vs 56.49 (32.42-94.25) pg/mL, p = 0.027. Multiple linear regression analysis of all women showed that NT-proBNP level was reversely associated with the presence of depressive symptoms, waist circumference and heart rate and positively connected with age. In the group of women with depressive symptoms, we observed negative correlations between NT-proBNP level and insulin concentration at 60 min of OGTT, diastolic blood pressure and a positive correlation with SHBG. CONCLUSIONS: NT-proBNP level is decreased in women with depressive symptoms, which might be connected with metabolic disturbances in this group.

The Immunoseasonal Theory of Psychiatric Disorders.

Although the influence of the weather on the well-being and mental health of psychiatric patients has been widely seen, the relationships between various seasonal weather factors and depressive, manic, anxiety, and psychotic states have not been systematized in the literature. The current article describes the seasonal changes in weather-related immune responses and their impact on the development of episodes of depression, mania, psychosis, and anxiety, highlighting the T-helper 1 (Th1) and Th2 immune balance as their potential trigger. In autumn-winter depression, the hyperactivation of the Th1 system, possibly by microbial/airborne pathogens, may lead to the inflammatory inhibition of prefrontal activity and the subcortical centers responsible for mood, drive, and motivation. Depressive mood periods are present in most people suffering from schizophrenia. In the spring and summertime, when the compensating anti-Th1 property of the Th2 immune system is activated, it decreases the Th1 response. In individuals immunogenetically susceptible to psychosis and mania, the inhibition of Th1 by the Th2 system may be excessive and lead to Th2-related frontal and subcortical hyperactivation and subsequent psychosis. In people suffering from bipolar disorder, hyperintense changes in white matter may be responsible for the partial activation of subcortical areas, preventing full paranoid psychosis. Thus, psychosis may be mood-congruent in affective disorders.

Oxidative Stress Biomarkers among Schizophrenia Inpatients.

BACKGROUND: Finding the associations between schizophrenia symptoms and the biomarkers of inflammation, oxidative stress and the kynurenine pathway may lead to the individualization of treatment and increase its effectiveness. METHODS: The study group included 82 schizophrenia inpatients. The Positive and Negative Symptoms Scale (PANSS), the Brief Assessment of Cognition in Schizophrenia (BACS) and the Calgary Depression in Schizophrenia Scale were used for symptom evaluation. Biochemical analyses included oxidative stress parameters and brain-derived neurotrophic factor (BDNF). RESULTS: Linear models revealed the following: (1) malondiadehyde (MDA), N-formylkynurenine (N-formKYN), advanced oxidation protein products (AOPP), advanced glycation end-products of proteins (AGE) and total oxidative status (TOS) levels are related to the PANSS-total score; (2) MDA, reduced glutathione (GSH) and BDNF levels are related to the PANSS-negative score; (3) TOS and kynurenine (KYN) levels are related to the PANSS-positive score; (4) levels of total antioxidant status (TAS) and AOPP along with the CDSS score are related to the BACS-total score; (5) TAS and N-formKYN levels are related to the BACS-working memory score. CONCLUSIONS: Oxidative stress biomarkers may be associated with the severity of schizophrenia symptoms in positive, negative and cognitive dimensions. The identification of biochemical markers associated with the specific symptom clusters may increase the understanding of biochemical profiles in schizophrenia patients.

Old and New Biomarkers of Alcohol Abuse: Narrative Review.

The harmful use of alcohol is responsible for 5.1% of the global burden of disease, and the early detection of alcohol problems may prevent its development and progression. Therefore, the aim of the study is to review traditional and new biomarkers associated with alcohol use. The nature and practical application and limitations of alcohol biomarkers in the diagnosis and monitoring of drinking are reviewed. Despite the limited specificity and sensitivity in alcohol drinking detection, traditional biomarkers are useful in clinical practice, and new generations of biomarkers, e.g., proteomic markers, are in need of further investigation. Traditional biomarkers are broadly available and cost-efficient, providing valuable data on the complications of drinking and prognosis, as well as on concurrent conditions affected by drinking. The most important challenge in the future will be to translate methodically advanced methods of detecting alcohol markers into simpler and cheaper methods. Larger population studies are also needed to test the usefulness of these potential markers of alcohol use.

The Lack of Influence of Homozygous Long Allele of the 5-HTTLPR Gene on the Severity of Alcohol Craving During 6 Weeks of Rehab Hospitalisation in Comparison to Not Homozygous and Homozygous Short Alleles - Preliminary Report.

Purpose: The aim of this study was to assess changes in the severity of alcohol craving according to allelic variants of the 5-HTTLPR gene polymorphism during hospitalisation and their association with selected clinical variables in alcohol-dependent patients. Patients and Methods: The study is exploratory. Participants were investigated at the 2nd and 6th week of alcohol-dependence therapy in the addiction treatment unit. Recruitment was conducted among alcohol-dependent patients from several Polish drug treatment centres. The total sample size was 130 persons (12 females and 118 males). Study subjects' mean age was 43.0 years. Patients were investigated twice by using the Penn Alcohol Craving Scale (PACS) and Beck Depression Inventory (BDI), and once by using Short Alcohol Dependence Data Questionnaire (SADD) and taking a swab for genetic testing. The polymorphism of the gene encoding the serotonin transporter 5-HTTLPR (SLC6A4) was determined from isolated DNA and its homozygous variants of short/short or long/long alleles and heterozygous short/long alleles were analysed. Results: At 6th week of the follow-up, there was a decrease in the severity of alcohol craving in half of subjects with the short/short allele (p = 0.033) and in one-fifth of subjects with the long/short allele (p = 0.002) of the 5-HTTLPR gene. In subjects with long/long allele of the 5-HTTLPR gene, there was no change in the severity of alcohol craving between 2nd and 6th weeks of the study (p = 0.242). Conclusion: There was no statistical influence of the homozygous long allele of the 5-HTTLPR gene on severity of alcohol craving during 6 weeks of rehab hospitalisation in comparison to not homozygous and homozygous short alleles. The s-allele was associated with decrease of alcohol craving. It may point on the potential need for differentiated rehabilitation methods depending on the genetic diversity of addicted patients and its role in the severity of alcohol craving.

The Effect of Neoglandin on the Activity of N-Acetyl-ß-D-Hexosaminidase in the Serum and Urine of Alcohol-Dependent Men.

Dietary supplementation of gamma-linolenic acid (GLA) in the form of a commercial drug neoglandin (containing GLA and vitamin E), in people following alcohol abuse allows bypassing of the ineffective delta-6-desaturase system involved in the transformation of linoleic acid into GLA. Determination of the activity of N-acetyl-ß-D-hexosaminidase (HEX) in the serum and urine reflects neoglandin action on the catabolism of glycoconjugates and the functioning of liver and kidneys in people following alcohol abuse. MATERIAL AND METHODS: The serum and urine were collected from men with alcohol dependence, treated (n = 31, age 33.16 ± 9.72 years) and not treated (n = 50, age 35.46 ± 11.37 years) with neoglandin. HEX activity were assayed in the supernatants by the colorimetric method, with the p-nitrophenyl derivative of sugar as substrate. RESULTS: Our study on alcoholic men not treated with neoglandin indicates a significantly higher concentration of the serum and urinary HEX activity (nKat/L) on day 1 compared to days 7, 10, 14 and 30 (p < 0.001). For days 14 and 30 (p < 0.01), the urinary HEX activity was expressed in µKat/kgCr. No significant differences were observed in the activity of serum (nKat/L) and urinary (nKat/L and µKat/kgCr) HEX in alcoholics during treatment with neoglandin compared to day 1 of neoglandin treatment. We found significantly different (p < 0.05) concentration of HEX activity (nKat/L) in serum of alcohol-dependent men treated with neoglandin compared to those not taking neoglandin on days 7, 10, 14 and 30 of treatment. The urinary concentration of HEX activity (nKat/L) on days 1, 4, 10 and 30 and HEX activity in µKat/kgCr on days 1, 4 and 7 it was significantly higher (p < 0.05) during the treatment of alcohol-dependence without the use of neoglandin as compared to alcoholics treated with neoglandin. We found a positive correlation between the amount of alcohol consumed and the urinary activity of HEX in the early phase after alcohol withdrawal and a lack of correlation between the HEX activity in serum and urine of alcohol-dependent men not treated with neoglandin. CONCLUSIONS: Neoglandin supplementation in alcoholic men significantly slows down the catabolism of glycoconjugates, thus reducing the effects of ethanol poisoning that are harmful to the kidneys. Neoglandin reduces the harmful effects of ethanol poisoning more on the kidneys than on the liver. The activity of HEX in the serum may be used in monitoring the treatment of alcoholism and whether alcohol reuse occurred during the therapy. In the early stages of alcohol withdrawal, urinary HEX activity can be used as a marker of the amount of alcohol consumed during previous alcohol abuse.

Urine 3-Nitrotyrosine and Serum HDL as Potential Biomarkers of Depression.

Depression (MDD) is a leading psychiatric entity worldwide, with a high impact on individual life and public health. In recent years, efforts have been made to elucidate its biological underpinnings. MDD biomarker research provides promise for a better understanding of the biochemical processes involved in its pathogenesis. Oxidative and nitrosative stress (O&NS) and lipid disturbances are reported as major factors favoring the occurrence of depression. A total of 29 patients with MDD and 30 healthy volunteers were examined using the Hamilton Depression Scale (HAM-D), the Hamilton Anxiety Scale (HAM-A), and the Beck Depression Inventory (BDI). Blood and urine were collected to search for potential MDD biomarkers. O&NS parameters and ß-amyloid were assessed in the urine, while cholesterol fractions were assessed in the blood. The group of depressed patients was characterized by higher concentrations of urine superoxide dismutase (SOD), 3-nitrotyrosine (3-NT), catalase (CAT), reduced glutathione (GSH), tryptophan (TRY), and serum triglycerides (TGA), along with lower levels of serum high-density lipoprotein (HDL). Elevated urine 3-NT and decreased serum HDL, considered together, were found to have the greatest potential as markers of depression. The study supports the importance of oxidative stress and cholesterol disturbances in MDD. Further research is required to assess their clinical usefulness as markers.

Confusion of Alcohol Craving With Food Hunger in Alcohol-Dependent Individuals Entering In-Patient Drug Treatment.

AIM: To identify the distinguishing characteristics of alcohol dependent patients who confuse alcohol cravings with pre-meal hunger. METHODS: Data were collected at interview on sociodemographic status, clinical status and anthropometry in 179 patients (163 men and 16 women) undergoing in-patient treatment for alcohol dependence. RESULTS: A comparison of the patient subgroups studied showed that patients who did not confuse, and those who did confuse, alcohol craving with pre-meal hunger differed significantly in terms of alcohol craving scale scores (9 vs. 4 points). Patients confusing alcohol cravings with pre-meal hunger were more likely to recognize that experiencing severe pre-meal hunger can cause relapse (67.9 vs. 22.8%) and that not being able to distinguish between the sensations under study also increases the risk of breaking abstinence (75.0% vs. 50.4%). This was independent of severity of dependence and intensity of recent alcohol consumption. CONCLUSIONS: Alcohol-dependent persons who confuse alcohol craving with pre-meal hunger differ from those who do not confuse these hunger pangs in terms of feeling stronger alcohol craving and more frequent occurrence of symptoms accompanying the feeling of alcohol craving during pre-meal hunger. At the start of treatment for alcohol withdrawal, alcohol-dependent individuals who report confusing alcohol cravings with pre-meal hunger are less confident of maintaining abstinence. This is relevant to treatment. The role of possible confounders (depressive symptoms, cognitive and educational deficiency) could not be elucidated definitively.

Impact of pregnancy/childbirth on dispositional optimism in the context of risk of depression, mental health status and satisfaction with life.

Introduction: Life optimism is an inseparable element accompanying every human being. It takes different values depending on the life situation. The present study aimed to measure the level of dispositional optimism in postpartum and pregnant women, compared to women who are not pregnant and have never given birth in Poland, Greece, Turkey, Belarus, and Russia, depending on the level of life satisfaction, risk of depression and mental health. Materials and methods: A case-control study was carried out among 2017 women, including 584 pregnant women, 528 postpartum women, and 906 women who had never been pregnant and had never given birth (control group) from Poland, Greece, Turkey, Belarus, and Russia.The study used the LOT-R Life Orientation Test, the Beck Depression Scale (BDI), the Satisfaction With Life Scale (SWLS), the GHQ- 28, and the Edinburgh Postnatal Depression Scale (EPDS) - only in the postpartum group. Results: Women from the control group showed an average level of optimism, obtaining an average of 16 points in Belarus, 13.4 points in Poland, 13.3 points in Greece, 13.5 points in Turkey, and Russia - 16.3 points. Pregnant women from Belarus had a high level of optimism (17 points), and in other countries, an average level of optimism was in Poland - 14.5 points, Greece - 14.0 points, Turkey - 14.3 points, and Russia - 16.5 points. Women after childbirth had a high level of optimism in Belarus (17.4 points) and Russia (17.2 points), and in other countries had the average level of optimism. In these countries, the lowest level of optimism was found in non-pregnant women. No significant correlation between age and life optimism was found in any group. In Poland, life optimism increased with age in women who had never been pregnant, and in Turkey, in women who were pregnant and after childbirth. Conclusion: Pregnant women from Belarus had a higher level of optimism than other countries. Non-pregnant women had an average level of optimism. Future studies should include larger groups of women and consider other factors that may additionally contribute to dispositional optimism.

Do Circulating Redox Biomarkers Have Diagnostic Significance in Alcohol-Intoxicated People?

The toxic properties of ethanol are inextricably linked to oxidative stress. Despite many reports on the effects of alcohol dependence on blood redox homeostasis, there are no data on the oxidative stress profile in alcohol-poisoned cases. There are also no data on the diagnostic usefulness of redox biomarkers determined post-mortem in various biological fluids. This work investigates the utility of enzymatic and non-enzymatic antioxidant barrier, redox status, and oxidative/nitrosative stress biomarkers in different biological fluids (such as blood, urine, vitreous humor, and cerebrospinal fluid) in the post-mortem study of patients with acute alcohol intoxication. The study group included those who died due to acute ethanol intoxication (n = 22). The research showed a significant increase in glutathione peroxidase activity, total antioxidant status, ferric reducing antioxidant power, and tryptophan concentration only in the study group's urine compared to the control. In other circulating fluids, both antioxidant enzyme activities and glycoxidation product concentrations were not significantly different in individuals who died of alcohol overdose compared with those who died suddenly. We also did not observe a connection between oxidation-reduction balance and the amount of alcohol consumed before death. These unexpected observations may be caused by irreversible post-mortem changes occurring at the cellular level due to autolysis and putrefaction. In summary, the use of circulating body fluids to assess redox homeostasis is limited in the post-mortem analysis. Our results indicate the increased stability of urine collected post mortem compared to other circulating bioliquids. Further studies are needed to assess the intensity of oxidative and carbonyl stress in ethanol-damaged organs and the effects of post-mortem processes on cellular redox balance.
