The relationship between perceived false self, academic burnout, and mental health problems","authors":"Katarzyna Tomaszek","doi":"10.12923/2353-8627/2023-0021","DOIUrl":"https://doi.org/10.12923/2353-8627/2023-0021","url":null,"abstract":"Introduction: False self is defined as the discrepancy between what we show and what we truly think and feel, and is associated with mental health and social problems. The present study aimed to examine the perception of false self-relationships with emotions, and educational and mental health problems. Specifically, the mediation effects of emotional regulation strategies and academic burnout on the association between perceived false self and depressive symptoms as well as life satisfaction were tested. Material and methods: The study design was cross-sectional. A paper-pencil method of data collection was used. The survey included the Academic Burnout Inventory (MBI-SS), the Perceived False Self Scale (POFS), the Depressive Symptoms Questionnaire (CES-D), and the life satisfaction scale (SWS). A total number of 149 participants took part in this study (aged: M=21.09; SD=1.72; 84.6% women). Results: The findings indicate that the perceived false self, emotional suppression, cognitive reappraisal, and academic burnout explain 31% of depressive symptoms and 31% of life satisfaction. The perceived false self was associated indirectly with depressive symptoms and life satisfaction via (1) emotional suppression, (2) academic burnout, and (3) emotional suppression, cognitive reassessment, and academic burnout altogether. Conclusions: Findings confirmed that inauthenticity is connected to mental health impairment and educational problems. Hiding the true self is associated with the suppression of true emotions, and for this reason, a person may experience tension. Consequently, a long-term struggle with distress generates burnout syndrome and an increased risk of mental health problems. In preventive interventions, it is important to include actions that strengthen authentic responses.

{"title":"From the party to the therapy – MDMA as an alternative for the existing methods of Post-traumatic Stress Disorder treatment","authors":"Wiktoria Bojarska, Karolina Bury, Radosław Januszczak, Bartosz Burda","doi":"10.12923/2353-8627/2023-0020","DOIUrl":"https://doi.org/10.12923/2353-8627/2023-0020","url":null,"abstract":"Introduction: Post-traumatic Stress Disorder (PTSD) is a mental illness caused by exposure to a traumatic event. The current treatment includes trauma-focused psychotherapy along with selective serotonin reuptake inhibitors (SSRI). It is estimated that for about 40-60% of patients it does not bring the desired improvement, which prompted scientists to look for new methods of pharmacotherapy. The most promising compound is MDMA. Material and methods: The purpose of this paper is to review publications from years 2020-2022 available on the PubMed platform about using MDMA in PTSD treatment, using words: MDMA, PTSD, MDMA and PTSD. Discussion: MDMA (3,4-methylenedioxymethamphetamine) is a psychoactive substance that increases brain levels of serotonin, dopamine and norepinephrine. Studies show that this treatment reduces symptoms of severe PTSD, comparing to placebo and current treatment. Patients reported improvement in terms of well-being, number of nightmares, sleep disorders, self-perception or interpersonal relationships. The positive effects of MDMA therapy were long-lasting. They persisted for 12 months after the end of treatment. According to research, MDMA reduces the symptoms of concomitant disorders, e.g. of eating disorders or by reducing alcohol consumption, without increasing the risk of abuse of other substances or MDMA itself. In addition, MDMA is believed to improve psychotherapy by allowing patients to revisit the traumatic event without negative symptoms. Side effects of therapy are less serious and occur less often than in the case of previously used SSRIs. Conclusions: Abovementioned observations show that MDMA-assisted PTSD psychotherapy is a promising alternative to the existing methods and brings hope for patients with the most severe or treatment-resistant course.

Due to the unsatisfactory results of existing treatment, research is being undertaken into new forms of therapy. One such method is transcranial magnetic stimulation. This technique involves applying a magnetic field to the central nervous system. Successive magnetic pulses are delivered at a specific frequency causing neurons depolarization. Such repetitive exposure allows for long-term modulation of cortical excitability, and thus can lead to specific clinical effects. This paper discusses scientific reports about the treatment of alcohol dependence using transcranial magnetic stimulation (both papers on conventional repetitive transcranial magnetic stimulation, theta burst stimulation and deep transcranial magnetic stimulation are included). Material and methods: Based on the search of the PubMed and Science Direct bibliographic databases, 12 studies published in the years 2010-2022 were selected. The results were tabulated to clearly compare differences in the parameters of stimulation, its location, as well as the effectiveness of the intervention used. Results: The results of selected studies were compared. Differences in methodology were pointed out and the problem of high dropout rate in addiction research was discussed. Conclusions: Currently, there is insufficient evidence to recommend the use of transcranial magnetic stimulation in the treatment of alcohol dependence. The results of the studies conducted to date are mixed. This is due, among other things, to the choice of different protocols, techniques and stimulation sites. For a reliable assessment of the effectiveness of this form of therapy, more andomized double-blind clinical trials and a sufficiently long follow-up period are needed.

As the most common personality disorder, BPD features behavioural, emotional and social dysfunctions. It often co-occurs with self-harm, suicidal tendencies and substance abuse. To date, pharmacological treatment does not provide sufficient therapeutic effects. The aim of our study is to analyse the neurobiological, genetic and environmental components in the aetiopathogenesis of BPD and to collect data on the innovative use of lithium and naltrexone in the therapy of BPD. Methods: Basing on PubMed and Google Scholar databases using the following keywords: borderline, lithium, naltrexone for papers published from 1979 to 2022. Results: Difficult childhood, and emotional, sexual and physical abuse are the strongest predictors of BPD development. The core symptoms of BPD may be related to dysfunction of the serotonin, dopaminergic, endogenous system and opioid systems. Variation in 5-HTT, COMT, FKBP5 and oxytocin receptor genes may influence the course of BPD. Imaging studies have shown structural and functional abnormalities in the prefrontal cortex, amygdala and hippocampus. Lithium reduces impulsivity, aggression, suicidal tendencies and self-harm in BPD. Naltrexone may effectively reduce self-harm without suicidal tendencies, impulsivity, substance abuse and suicidality. Conclusions: No unified model has been developed to account for environmental, genetic and neurobiological components in the pathogenesis of BPD. Understanding the mechanisms is a crucial step towards personalising treatment. The use of lithium and naltrexone may have positive therapeutic effects. Randomised clinical trials are required to establish the efficacy and safety of both drugs in long-term treatment.

Material and methods: Pregnant women who delivered between September 2019-June 2021 at a Mouth Sinai Health System practice in New York City were identified. Baseline information about maternal health, pregnancy outcomes, and postpartum visits were obtained from electronic health records. Edinburgh Postnatal Depression Scores (EPDS) were used as a postpartum depressive symptom marker. Three analyses were performed to compare scores between: (1) women who delivered before and after COVID-19, (2) pregnant women who delivered after the pandemic who did and did not contract COVID-19, and 3) pregnant women eligible for the COVID-19 vaccine who were and were not vaccinated. Results: A total of 1.797 pregnant women were identified. Pregnant women during the pandemic had statistically significant higher rates of pre-existing mental health diagnoses and psychiatric medicine use compared to those who were pregnant before. No difference was observed in EPDS scores of pregnant women who delivered before vs. after the start of COVID-19 nor between COVID-vaccinated and unvaccinated pregnant women. Women who contracted COVID-19 in pregnancy had lower EPDS scores than women who did not. Results remain unchanged after controlling for baseline mental health diagnoses. Conclusions: In our cohort, EPDS scores were not associated with pregnancy during the pandemic, COVID infection while pregnant, or COVID vaccination during pregnancy. However, we did identify a higher incidence of baseline mental health diagnoses during the COVID pandemic, but that did not lead to a higher rate of positive screens for postpartum depression.","PeriodicalId":56342,"journal":{"name":"Current Problems of Psychiatry","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135097015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A structured, detailed interview of mothers and an original survey containing questions concerning lactation and nutrition in the neonatal and infant periods were carried out. Mothers of children with a subsequent autism diagnosis were also asked about worrying symptoms that occurred while breastfeeding. Material and methods: The sample material was obtained from mothers with several children whereas the child diagnosed with autism was in most cases the second one and had healthy siblings. Most surveyed mothers fed children in a natural way at the same time having lactation and nutrition problems in newborns and infants. The paper also presents developmental difficulties at a very early stage reported by mothers in spite of the fact that the full diagnosis of developmental disorders was made at the age of 4 on average. Results: Non-neurotypical symptoms observed by mothers cover the whole range of sometimes very subtle manifestations – from encephalitic scream, sleep disorders, breastfeeding problems, atypical responses, lack of emotional reciprocity to the disorders of sensory processing as well as motor and neurological problems. Conclusions: The study draws attention to the issue of integral child’s development in the neonatal and infant period, the significance of discreet irregularities in the development at a very early stage, which, when combined with the simple screening methods assessing the risk of autism, may be of key importance for timely diagnosis and initiation of adequate forms of therapy.

Its daily supplementation regulates calcium metabolism, inflammatory and neuromodulatory processes. More importantly, vitamin D may be an important factor in reducing the risk of suicide among psychiatric patients. This review aims to describe the potential positive effect of vitamin D supplementation in preventing suicide attempts.\u0000Method: The literature review was conducted by search of articles in English and Polish languages on PubMed, Medline, and Google Scholar, published from 1974 to the 1st of April 2023, following SANRA requirements. The search utilized the following keywords: vitamin D, vitamin D deficiency, vitamin D supplementation, suicide, depression, bipolar disorder, schizophrenia, ADHD, anxiety, and autism. The analysis encompassed original studies, meta-analyses, randomized controlled trials, and review articles.\u0000Results: There is a limited number of studies investigating the impact of vitamin D supplementation on suicide risk in individuals with mental illness. Several studies suggest that vitamin D may have a beneficial effect on symptoms of mental illnesses. However, the exact mechanism through which vitamin D exerts its therapeutic effects on mental health remains unclear. Incorporating vitamin D into the treatment of the mental disorders such as depression, schizophrenia, bipolar disease, ADHS, autism spectrum disorder, and anxiety, as well as supplementing it during pregnancy and throughout life, could potentially be an effective therapeutic adjunct for suicide prevention approach.\u0000Conclusions: According to all the research and gathered data, there is a correlation between Vitamin D supplementation and a decrease in suicide risk among patients suffering from mental disorders. Several lines of evidence have shown a positive impact on mental health in patients suffering from mental diseases.

Overeating may be also considered as an early warning sign of additional psychological issues, e.g. poor well-being, depression and suicide ideation. Although a vast body of literature has examined pandemic Covid-19 related stressors as potential risk factors for eating problems, no studies have explored e-learning stress and burnout as a characteristic that may contribute to overeating among adolescents during this global crisis. The main goal of this study was to test the mediation effect of social resources on the associations between e-school stress and burnout, adolescents’ psychological well-being and overeating.\u0000Method: Path analysis was conducted on the results of the E-Learning Burnout Scale, the Psychological Well-Being Scale, the Short Social Resource scale, and one-item scales for Overeating behaviours and Online School Stress. Cross-sectional data were collected via Google forms from 186 students (M=15.93 years; SD=1.70; 60% girls).\u0000Results: Social resources and e-learning burnout had a significant direct effect on overeating behaviours frequency. The significant indirect effect of psychological well-being via social resources on overeating behaviours was confirmed, however the indirect effect of e-learning burnout was insignificant. Student stress had a significant indirect effect on overeating behaviours via e-learning burnout, and via social resources.\u0000Conclusions: E-learning stress and burnout during the Covid-19 pandemic are directly related to the reduction of the individuals’ resources used to effectively cope with negative emotions and distress in everyday life, which, in turn, may heighten the risk of engaging in overeating behaviours.\u0000\u0000Keywords: overeating behaviours, online student burnout, social resources, adolescence","PeriodicalId":56342,"journal":{"name":"Current Problems of Psychiatry","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74297470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
