Patients with chronic bipolar disorder show impairments in interpreting literary fiction - A preliminary explorative study with the short story task.

INTRODUCTION: Theory of mind (ToM) is a crucial skill in navigating and functioning in the social world. Significant ToM impairment was consistently found in bipolar disorder; it can be both a state and trait marker of the disorder. However, most of the ToM tests are not sensitive enough to detect subtle individual differences, which would be necessary for an individualized treatment plan. The Short Story Task (SST) is a new way to sensitively assess individual differences in ToM performance. The aim of the study was to test the feasibility of SST in patients with bipolar disorder. METHOD: 31 persons (11 male, 20 female) with bipolar I disorder and 31 healthy individuals (15 males and 16 females) as a control group were recruited. SST was used to evaluate ToM performance. The SST uses a Hemingway novel, in which the patient is presented with a realistic social situation, where the motivations of the characters and the underlying relationships of events are not explicitly described. RESULTS: In the explicit mental state reasoning questions the CG (M = 8.06) had significantly higher (p < 0.001) scores than the persons with bipolar I disorder (M = 5.03). There was no ceiling effect for explicit ToM scores in either group. Participants in CG (M = 8.03) also significantly outperformed (p = 0.006) the BG participants (M = 6.55) in the comprehension questions. The spontaneous mental state inference question was performed equally (M = 0.23) in both groups. Group assignment (t = -3.503, p < 0.001), comprehension score (t = 2.864, p = 0.006), and spontaneous mentalization (t = 2.846, p = 0.006) significantly predicted the explicit ToM performance. CONCLUSIONS: Overall, we found that the Short Story Task is a promising tool for measuring ToM in patients with bipolar disorder without ceiling effect. Primarily explicit ToM was found to be deficient, which corresponds well with the ToM literature in bipolar disorder. Contrary to our hypothesis we could not detect impairment in spontaneous ToM and found that patients living with bipolar disorder also showed deficits in comprehension. The lack of assessment of neurocognitive skills is a significant limitation of the current study.

Investigation of peripheral inflammatory biomarkers in association with suicide risk in major depressive disorder.

Suicide is the most severe complication of major depressive disorder (MDD). Novel research assumes the role of immunological dysregulation in the background - several studies have reported alterations in the number of inflammatory cells related to both MDD and suicidality. There are currently no objective, routinely measured parameters to indicate suicidal vulnerability. However, altered inflammatory cell numbers and ratios have been proposed as potential biomarkers of suicide risk (SR). The present research aims to examine changes of these values related to increased SR in MDD as an assumed inflammatory state. We investigated laboratory parameters of psychiatric in-patients diagnosed with MDD (n = 101) retrospectively. Individuals with recent suicide attempt (SA) (n = 22) and with past SA (n = 19) represented the high SR group. MDD patients with no history of SA (n = 60) composed the intermediate SR group. We compared the number of neutrophil granulocytes, monocytes, lymphocytes, platelets, white blood cell count (WBC), neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), red blood cell distribution width (RDW) and erythrocyte sedimentation rate (ESR). Furthermore, we evaluated alterations of these parameters related to antidepressant (AD) and antipsychotic (AP) treatment, which have been proved to have anti-inflammatory effects. We found a significant increase in neutrophil granulocyte count, NLR, monocyte count, MLR, WBC and ESR in patients with recent SA compared to patients with no history of SA. Moreover, there was a significant elevation in monocyte count, MLR, ESR and RDW in patients with high SR compared to patients with intermediate SR. AD treatment resulted in a significant decrease in neutrophil granulocyte count and NLR, however, it did not affect monocyte count and MLR. Assuming immunological mechanisms in the background of MDD and suicidality, our findings support the role of NLR as a biomarker of acute SR, though its alterations may be masked by possible anti-inflammatory effects of AD treatment in the long term. However, MLR, a marker exhibiting changes which are not attenuated by pharmacotherapy, may be a possible indicator of both acute and long-term suicidal vulnerability.

Physical workload and cardiopulmonary parameters in relation to individual capacity of bulk waste workers - a cross-sectional field-study.

PURPOSE: Waste collection is considered particularly heavy work, although no previous study has yet investigated the strain of bulk waste collection. The aim of this study is to determine the workload of bulk waste workers in practice. METHOD: We conducted a cross-sectional field-study. Fourteen male volunteers from the bulk waste collection of the municipal sanitation department in Hamburg, Germany, were included. Performance was determined by cardiopulmonary exercise testing under laboratory conditions. During the shift, each worker was accompanied by a researcher, and heart rate (HR) was recorded under field conditions using an HR watch with a belt system. We examined mean HR, relative heart rate (RHR), relative aerobic strain (RAS), calculated oxygen uptake ([Formula: see text])  and individual ventilatory threshold 1 (VT1) as parameters of workload during their daily work. RESULTS: During the shift, HR was scaled: 102 bpm (SD 10.2), RHR: 36.9%, [Formula: see text]: 1267 ml/min (SD 161), RAS: 49.4% (SD 9.3), and [Formula: see text] in relation to VT1: 75% (SD 18.5). There was no significant difference between oxygen consumption during the main task of lifting and carrying bulky waste and the individual [Formula: see text] at VT1. CONCLUSION: Although the burden of the main task of lifting and carrying bulky waste is very high (at VT1 for more than 3 h), interruptions from other tasks or formal breaks spread the burden over the entire shift. The total workload exceeded most recommendations in the literature across the different work periods. However, the total burden remains below VT1, the only parameter that takes individual endurance performance into account. We recommend again VT1 as an individual upper limit for prolonged occupational work.

Polymorphisms in genes of melatonin biosynthesis and signaling support the light-at-night hypothesis for breast cancer.

Light-at-night triggers the decline of pineal gland melatonin biosynthesis and secretion and is an IARC-classified probable breast-cancer risk factor. We applied a large-scale molecular epidemiology approach to shed light on the putative role of melatonin in breast cancer. We investigated associations between breast-cancer risk and polymorphisms at genes of melatonin biosynthesis/signaling using a study population of 44,405 women from the Breast Cancer Association Consortium (22,992 cases, 21,413 population-based controls). Genotype data of 97 candidate single nucleotide polymorphisms (SNPs) at 18 defined gene regions were investigated for breast-cancer risk effects. We calculated adjusted odds ratios (ORs) and 95% confidence intervals (CI) by logistic regression for the main-effect analysis as well as stratified analyses by estrogen- and progesterone-receptor (ER, PR) status. SNP-SNP interactions were analyzed via a two-step procedure based on logic regression. The Bayesian false-discovery probability (BFDP) was used for all analyses to account for multiple testing. Noteworthy associations (BFDP < 0.8) included 10 linked SNPs in tryptophan hydroxylase 2 (TPH2) (e.g. rs1386492: OR = 1.07, 95% CI 1.02-1.12), and a SNP in the mitogen-activated protein kinase 8 (MAPK8) (rs10857561: OR = 1.11, 95% CI 1.04-1.18). The SNP-SNP interaction analysis revealed noteworthy interaction terms with TPH2- and MAPK-related SNPs (e.g. rs1386483R ∧ rs1473473D ∧ rs3729931D: OR = 1.20, 95% CI 1.09-1.32). In line with the light-at-night hypothesis that links shift work with elevated breast-cancer risks our results point to SNPs in TPH2 and MAPK-genes that may impact the intricate network of circadian regulation.

Does working in an extremely cold environment affects lung function?: 10 years follow-up.

OBJECTIVE: The aim of this study is to investigate whether there is an association between brief but repeated exposures to extremely cold temperatures over many years and pulmonary function. METHODS: We performed a retrospective analysis of the data collected over 10 years in the context of the extended medical examinations of storeworkers exposed to extremely cold temperatures. We considered forced vital capacity (FVC), forced expiratory volume in one second (FEV1), Tiffeneau-Pinelli index (FEV1/FVC), CO diffusion capacity (DL,CO) and Krogh-factor (CO diffusion capacity relative to recorded alveolar volume, DL,CO/VA) reported as %-predicted. We analysed trends in outcome parameters with linear mixed models. RESULTS: 46 male workers participated in at least two extended medical examinations between 2007 and 2017. Overall 398 measure points were available. All lung function parameters had values above the lower limit of normality at the first examination. In the multivariate model including smoking status and monthly intensity of cold exposure (≤ 16 h/month vs. > 16 h/month) FEV1%-predicted and FVC %-predicted had a statistically significant positive slope (FEV1, 0.32% 95% CI 0.16% to 0.49% p < 0.001; FVC 0.43% 95% CI 0.28% to 0.57% p < 0.001). The other lung function parameters (FEV1/FVC %-predicted, DL,CO %-predicted, DL,CO/VA %-predicted) showed no statistically significant change over time. CONCLUSIONS: Long term intermittent occupational exposure to extreme cold temperatures (-55 °C) does not appear to cause irreversible deleterious changes in lung function in healthy workers, thus the development of obstructive or restrictive lung diseases is not expected.

The effect of reading literary fiction on the theory of mind skills among persons with schizophrenia and normal controls.

Introduction: Recent research data suggest that theory of mind (ToM) skills may improve after reading literary fiction. However, beside this short term favorable effect, regular long-term reading of literary fiction may also support ToM development or may improve ToM performance. The presence of impaired ToM abilities is well-documented in schizophrenia; however, the role of reading in these deficits is unknown. In the present study our aim was to assess the effect of prior reading experiences on theory of mind performance in patients with schizophrenia, and in healthy controls. Materials and methods: ToM assessment was done with the Short Story Task, which is based on the interpretation of a Hemingway short story. After reading the short story, questions were asked in an interview format regarding comprehension, explicit and implicit ToM skills, then comparative analysis of schizophrenia patients was performed (n = 47) and matched to a normal control (n = 48) group concerning deficits of ToM abilities. Participants were also stratified according to their prior reading experiences. Results: Previous reading experience was associated with better comprehension and explicit ToM performance both in patients with schizophrenia, and in healthy controls. However, the explicit ToM performance of patients with prior reading was still weaker compared to healthy controls with reading experiences. Path model analysis revealed that reading had a direct positive effect on ToM, and an indirect effect through improving comprehension. Conclusions: Prior reading experience is associated with better ToM performance not just in healthy controls but also in patients living with schizophrenia. Previous reading experience also improves comprehension, which in turn has a favorable impact on ToM. Our results support the idea that literary fiction reading may have a therapeutic potential in the rehabilitation of schizophrenia.

Accidents, diseases and health complaints among seafarers on German-flagged container ships.

BACKGROUND: For seafarers on the high seas health hazards are various and due to the setting also specific. The spectrum of job-related health impairments and accidents is mainly influenced by the maritime characteristics. The aim of this study is to assess the kind of accidents and the frequency of diseases and health complaints among seafarers on German container ships by evaluating medical log books. METHODS: A systematic analysis of 14,628 medical entries from 95 medical log books of 58 container ships under German flag from 1995 to 2015 was performed. This monocentric retrospective and descriptive study used information on accidents, diseases and health complaints among different occupational groups and medical treatment procedures for the analysis and evaluation. RESULTS: The analysis showed that more than one third of all consultations with the Health Officer on board are related to internal (33.7%) and surgical (31.3%) symptoms. Almost twenty percent of consultations were due to respiratory infections (19.6%) and accidents (17.9%). Accidents represented the most frequent reason for unfitness for sea service (31.2%). Based on occupational categories, most injuries occurred among deck crew (22.5%), followed by ratings working in the engine room (18.9%). In 106 cases, telemedical contact with a physician ashore was necessary. In total, 15 seafarers had to be evacuated from the ship for further medical treatment onshore. Medicine/drug application was the most common therapeutic measure on board, accounting for 77% of all consultations. CONCLUSIONS: The high proportion of health complaints and accidents among seafarers shows that there is a need to optimize medical care at sea and accident prevention, e.g. by standardized treatment algorithms or improving the medical training of Health Officers. The development and introduction of a digital patient file to record medical treatments on the vessels could also improve medical documentation on board.

Clinical protocol selection for alveolar ridge augmentation at sites exhibiting slight, moderate, and severe horizontal ridge deficiencies.

FOCUSED CLINICAL QUESTION: What factors identify the optimal bone augmentation techniques for managing slight, moderate, and severe horizontal alveolar ridge deficiency (ARD) at dental implant sites? SUMMARY: Horizontal ARD is a concern at a high proportion of sites receiving dental implants, and clinicians have developed a variety of surgical procedures to address such defects. In a particular case, selection of the optimal treatment may depend predominantly on defect severity, location (anterior versus posterior), and configuration (contained versus noncontained). This report provides a framework for selecting an augmentation method when presented with a slight, moderate, or severe horizontal ARD at a site requiring dental implant placement. CONCLUSION: Multiple treatment options are available for planned implant sites exhibiting horizontal ARD; severe posterior and slight anterior defects intuitively call for different approaches. Although rigid guidelines for selecting the optimal augmentation method do not exist, some techniques are poorly suited for esthetically demanding sites. A framework considering defect severity, location, and configuration may help guide clinical decisions on this topic.

[The role of socialisation in psychosexual development].

INTRODUCTION: In the recent research and interpretation of the genetical-biological and environmental-social factors shaping psychosexual development, in addition to scientific arguments, more and more ideological and political aspect have received unfortunate emphasis. OBJECTIVE: Since the literature investigating the development of gender identity and gender orientation has not only increased, but also polarized, it is timely to look at the scientific exchange of ideas and debates among the differing positions. METHOD: Exploring the significance of genetic, biological and social factors involved in the development of gender identity and gender orientation based on international literature data. RESULTS: Based on the current state of science it can be concluded that, in addition to the indisputably marked genetic-biological factors, education and social patterns, as well as the extremely complex environmental and media-related influence with its variable intensity and diverse emotional content also play a significant role in the psychosexual development. This is supported, among other observations, by the data indicating that homoerotic behavior is more common in people raised by same-sex couples. CONCLUSION: As psychosexual development is determined jointly by both genetic-biological and social factors (like education, media etc), belonging to a sexual minority group is not a choice, not the result of a personal decision. Therefore, any kind of discrimination in this regard is unacceptable. Further scientific studies are necessary to answer a large number of questions that still remain open.

Evolution of work ability, quality of life and self-rated health in a police department after remodelling shift schedule.

BACKGROUND: There exists a great diversity of schedules concerning the way shift work is organized and implemented with ample agreement regarding recommendable features of a shift system. In order to adapt the shift schedule of a metropolitan police department to current recommendations, a remodelled shift schedule was introduced in 2015. The aim of this study was to evaluate the potential associations between the remodelled shift schedule and work ability, quality of life and self-rated health after one and five years. METHODS: A controlled before-and- after study was conducted during the piloting phase (2015-2016) as well as a 5-year follow-up using paper questionnaires. Outcome parameters included work ability, quality of life and self-rated health. RESULTS: Work ability, quality of life and self-rated health improved after the first year of the newly implemented shift schedule among police officers working in the piloting police stations compared to those working according to the former schedule. In 5-year follow-up differences between indicators diminished. CONCLUSIONS: The implementation of a remodelled shift schedule including more 12-h shifts accompanied by more days off and a coherent weekend off duty was not associated with detrimental effects to work ability, quality of life or self-reported health among police officers.

Coronavirus Vaccination: Spike Antibody Levels in Health Workers after Six Months-A Cross-Sectional Study.

Healthcare workers bear a high risk of infection during epidemics and pandemics such as the current SARS-CoV-2 pandemic. Various new vaccines have been approved. We investigated the influence of the time elapsed since vaccination, as well as of vaccination schema, on health workers' spike antibody levels following their second vaccination. Blood samples were obtained from employees working at a German hospital between August 2021 and December 2021 on average half a year (range 130-280 days) after their second vaccination. Levels of SARS-CoV-2-IgG antibodies (spike and nucleocapsid protein) were qualitatively detected via chemiluminescent immunoassays (CLIAs). A previous infection with SARS-CoV-2 was an exclusion criterion. In total, 545 persons were included in this cross-sectional study. Most participants (97.8%) showed elevated anti-spike concentrations. Anti-spike levels differed significantly among vaccination schemas. Repeated vector vaccinations resulted in lower protective antibody levels. Higher age levels, immunosuppression and a longer time period since the second vaccination resulted in lower anti-spike levels. Women's antibody levels were higher, but not significantly. Since anti-spike levels drop after vaccination, further boosters are required to increase immunoreactivity. If two vector vaccines have been administered, it is possible that an mRNA booster might increase the anti-spike level.

Police officers' work-life balance, job satisfaction and quality of life: longitudinal effects after changing the shift schedule.

OBJECTIVES: To evaluate mental health-related outcomes of police officers 5.5 years after implementing a new alternating shift schedule which was supposed to improve their health and work-life balance. DESIGN: Pre-post study design with a baseline survey at the beginning of the piloting of the new shift schedule in 2015 and another survey 5.5 years later in 2020. SETTING: Police departments of a German metropolitan police force piloting the new shift schedule. PARTICIPANTS: 116 shift-working police officers out of a population of 1673 police officers at the follow-up date. INTERVENTIONS: New shift schedule based on occupational health recommendations. OUTCOMES MEASURES: Work-life balance, job satisfaction and quality of life. METHODS: Mixed analyses of variances were used to test the hypotheses of within-subject and between-subject differences regarding time and gender. RESULTS: We found partly significant differences between the baseline and follow-up survey for work-life balance (F(1, 114) = 6.168, p=0.014, ηp² = 0.051), job satisfaction (F(1, 114) = 9.921, p=0.002, ηp² = 0.080) and quality of life (F(1, 114) = 0.593, p=0.443, ηp² = 0.005). Neither significant differences between male and female police officers nor interaction effects of time and gender were found. CONCLUSION: An increase was found for each of the three outcomes 5.5 years after implementing the new shift schedule. The results contribute to the current state of research on mental health-related outcomes of working conditions in shift work. On this basis, recommendations for designing shift schedules can be deduced to promote mental health and job satisfaction for employees in shift work.

Ambiguous handedness and visuospatial pseudoneglect in schizotypy in physical and computer-generated virtual environments.

Virtual reality (VR) technology has increased clinical attention in the health care of schizophrenia spectrum disorders in both diagnoses of the symptoms and assessment of schizotypal traits. However, the exact nature of VR-induced positive treatment effect in schizotypy is still unknown. In this study, VR technology was used as a non-invasive neurocognitive trigger to test the asymmetric visuospatial representational instability found in individuals with high schizotypy. The study aimed to reveal the brain functional hemispheric laterality in physical and virtual realities in individuals with schizotypal traits. Fifty-one healthy, right-handed participants (24 males and 27 females) were enrolled through public advertisements. Hemispheric functional asymmetry was measured by the Line Bisection Task (LBT). The results revealed that (a) LBT bias in the physical reality showed a handedness-related leftward pseudoneglect, however, similar handedness-related pseudoneglect in VR has not been found. (b) Comparing LBT bias in physically real and VR environments showed rightward drift in VR environments independently to the degree of handedness. (c) The schizotypy has no association with handedness, however, the cognitive schizotypy is related to the LBT bias. Higher cognitive schizotypy in VR associated with left hemispatial pseudoneglect. In conclusion, schizotypy is associated with ambiguous behavioral and cognitive functional laterality. In individuals with high cognitive schizotypy, the VR environment enhanced the representational articulation of the left hemispace. This effect may be originated from the enhancement of the right hemisphere overactivation and is followed by a lower mental control of the overt behavior.

Restrictions of VC and DLCO in relation to asbestos-related computed tomographic findings quantified by ICOERD-based parameters.

BACKGROUND: Even almost 30 years after the ban on the use of asbestos in Germany, the effects of asbestos are still highly relevant in everyday clinical practice in occupational medicine. The aim of this study was to further investigate the significance of essential parameters of both pulmonary function diagnostics and imaging techniques (low-dose HR-TCT) for the prevention and early detection of asbestos-related morphological and functional lung changes. METHODS: Data from spirometry, body plethysmography and diffusion capacity, as well as CT images of the thorax, were retrospectively studied from 72 patients examined between 2017 and 2019 at the Institute for Occupational and Maritime Medicine (ZfAM), Hamburg, Germany. The subjects were divided into four subgroups according to the presence of comorbidities (concomitant cardiac diseases, obstructive ventilatory disorder, pulmonary function pattern consistent with emphysema, and no other pulmonary or cardiac diseases). These subgroups were analysed in addition to the overall collective. The CT images were evaluated according to the International Classification of Occupational and Environmental Respiratory Diseases (ICOERD) with radiological expertise. In addition, some asbestos-related parameters were newly quantified, and corresponding scores were defined based on ICOERD. Statistical analysis included the use of correlations and fourfold tables with calculation of Spearman's rho (ρ), Cohen's κ, and accuracy. RESULTS: Vital capacity (VC) is slightly reduced in the total collective compared to the normal population (mean 92% of predicted value), while diffusion capacity for CO (DLCO) shows predominantly pathological values, mean 70% of the respective predicted value. The CO transfer coefficient (DLCO/VA), which refers to alveolar volume (VA), also shows slightly decreased values (mean 87% pred.). Seventy-nine percent of patients (n = 57) had signs of pulmonary fibrosis on CT scans, and pleural plaques appeared in 58 of 72 patients (81%). Of the newly quantified additional parameters, particularly frequently described findings are subpleural curvilinear lines (SC, n = 39) and parenchymal bands (PB, n = 29). VC correlates well with the expression of pleural plaques (ρ = - 0.273, P < 0.05), and DLCO measures show a better correlation with fibrosis score (ρ = - 0.315, P < 0.01). A third, newly developed score, which includes the extent of pleural plaques and additional subpleural parameters instead of fibrosis parameters, shows significant correlations for both VC and DLCO (ρ = - 0.283, - 0.274, resp.; both P < 0.05). DISCUSSION: The importance of spirometry (VC) and diffusion capacity measurement (DLCO) as essential diagnostic procedures for the early detection of asbestos-related changes ‒ also including patients with relevant concomitant cardiac or pulmonary diseases ‒ was confirmed. Significant and better correlations between lung function changes (VC and DLCO) and abnormal CT findings are seen when parenchymal bands (PB), subpleural curvilinear lines (SC), and rounded atelectasis (RA) are quantitatively included into the evaluation, in addition to assessing the extent of pleural plaques alone. Therefore, when assessing CT images according to ICOERD, these parameters should also be quantified.

Implicit Mentalizing in Patients With Schizophrenia: A Systematic Review and Meta-Analysis.

INTRODUCTION: Mentalizing is a key aspect of social cognition. Several researchers assume that mentalization has two systems, an explicit one (conscious, relatively slow, flexible, verbal, inferential) and an implicit one (unconscious, automatic, fast, non-verbal, intuitive). In schizophrenia, several studies have confirmed the deficit of explicit mentalizing, but little data are available on non-explicit mentalizing. However, increasing research activity can be detected recently in implicit mentalizing. The aim of this systematic review and meta-analysis is to summarize the existing results of implicit mentalizing in schizophrenia. METHODS: A systematic search was performed in four major databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science. Eleven publications were selected. Five studies were found to be eligible for quantitative synthesis, and 9 studies were included in qualitative synthesis. RESULTS: The meta-analysis revealed significantly lower accuracy, slower reaction time during implicit mentalizing in patients with schizophrenia. The systematic review found different brain activation pattern, further alterations in visual scanning, cue fixation, face looking time, and difficulties in perspective taking. DISCUSSION: Overall, in addition to the deficit of explicit mentalization, implicit mentalization performance is also affected in schizophrenia, if not to the same extent. It seems likely that some elements of implicit mentalization might be relatively unaffected (e.g., detection of intentionality), but the effectiveness is limited by certain neurocognitive deficits. These alterations in implicit mentalizing can also have potential therapeutic consequences.Systematic Review Registration: https://www.crd.york.ac.uk/prospero/, identifier: CRD42021231312.

[Mentalizing deficit among patients with traumatic brain injury]. / Mentalizációs deficit traumás agysérült betegek körében.

BACKGROUND AND PURPOSE: Mentalization or theory of mind as an aspect of our social cognition, is our ability to infer mental states of others (intentions, desires, thoughts, emotions) and to predict their behavior accordingly. This function significantly affects our participation and orientation in the social world and plays an important role in conversational situations, social interactions, social integ-ration and adaptation. The brain regions that serve as the basis for mind-reading function can be damaged as a consequence of traumatic brain injury, which frequently occurs among the younger population. Traumatic brain injury can cause focal or diffuse cerebral injuries, often leading to theory of mind deficit. METHODS: In this topic such publications were researched that compared theory of mind ability between traumatic brain injury patients and control subjects (comparative case-control studies). We searched for the studies in the following internet based/online databases: PubMed, Web of Science, ScienceDirect, Google Scholar, APA PsycNET (PsycARTICLES) and EBSCO Host. The search was performed using the following key word combinations: theory of mind or mentalizing or social cognition AND traumatic brain injury or head/brain injury or diffuse axonal injury. RESULTS: Based on the results of the included and processed studies (21 pc), traumatic brain injury often leads to mentalization deficit with different severity. CONCLUSION: With this present review we aim to draw attention to the fact that the appearance and severity of mind reading dysfunction can considerably affect the outcome of the disease, the length of rehabilitation time and the prognosis of traumatic brain injury patients. Besides this, with this review, we aim to take sides in whether theory of mind ability is domain-specific or domian-general based on studies including traumatic brain injury patients.

Hikikomori: a possible mental health consequence of the COVID-19 epidemic / Hikikomori: a COVID-19-járvány egy lehetséges mentálhigiénés következménye.

Összefoglaló. A COVID-19-járvány kényszeru tartós szociális távolságtartást idézett elo az emberek között, ami az egyéb mentális rendellenességek és mentálhigiénés következmények mellett egy sajátos pszichiátriai jelenségre, a hikikomori állapotra hívja fel a figyelmet. A hikikomori tartós és szélsoséges szociális visszahúzódással járó jelenség, melynek kidolgozott kritériumrendszere egyelore még nem található meg a mentális rendellenességeket osztályozó diagnosztikus kézikönyvekben. Kialakulásának pontos mechanizmusáról még keveset tudunk, de az állapot megjelenése és az internet térnyerése között egyes szerzok szoros kapcsolatot látnak. Klasszikusan az egyén egy társadalmi szempontból megalázó vagy elonytelenül alakuló helyzet következtében vonul vissza fokozatosan egy önként vállalt izolációba. Bár a külvilág nem teljesen érdektelen számukra, azonban a retraumatizáció elkerülése érdekében leginkább online követik a világ történéseit és tartanak kapcsolatot másokkal. A COVID-19-pandémia - különösen a lezárások következményeként elotérbe kerülo online életvitelhez kötodoen - jelentos mértékben hozzájárult az internet térnyeréséhez, miközben a valós társas kapcsolatok kényszeruen beszukültek. Ez a konstelláció jelentos kockázati tényezonek tekintheto a hikikomori szempontjából, amely hosszú távon a világjárvány egyik nem várt szövodménye lehet, különösen az adolescens és a fiatal felnott korosztályban. Orv Hetil. 2021; 162(41): 1637-1642. Summary. The COVID-19 pandemic forced prolonged social distancing between people. This, among other mental disorders and mental health consequences, highlights a specific psychiatric phenomenon: the hikikomori condition. The hikikomori is a phenomenon of persistent and extreme social withdrawal. The condition's established diagnostic set of criteria is not yet to be found in diagnostic manuals classifying mental disorders. Little is known about the exact mechanism of its development, but some authors see a close link between its emergence and the rise of the internet. Typically, the individual gradually withdraws into a voluntary isolation as a result of a socially humiliating or unfavourable situation. Although the outside world is not completely irrelevant to them, they tend to follow online the events of the world and they also keep in touch with others mostly online in order to avoid retraumatization. The COVID-19 pandemic, particularly in relation to the rise of online lifestyles as a consequence of lockdowns, has contributed significantly to the more and more frequent use of the internet, while real social contact has been inevitably reduced. This constellation can be seen as a major risk factor for hikikomori, which in the long term could be an unanticipated complication of the pandemic, especially in adolescents and young adults.

Minor Physical Anomalies in Bipolar Disorder-A Meta-Analysis.

Introduction: Minor physical anomalies (MPAs) may reflect basic neurobiological features underlying bipolar disorders (BPD), as they are sensitive physical indicators of morphogenetic failure of the brain. Despite several researches about the presence of MPAs in BPD, the results are still controversial. Objectives: The aim of the present meta-analysis was to assess the standardized weighted mean effect sizes of MPAs in BPD and to examine if MPAs may be found predominantly in the head and/or facial regions in BPD patients compared to controls (HC). Methods: Four studies, involving 155 patients with BPD, and 187 HC, were involved in the analysis after searching the literature. For the investigation of MPAs in the peripheral (MPA-P) and in the head and facial regions (MPA-CF), two studies involving 121 BPD patients, and 133 HC passed the inclusion criteria. Results: The number of the MPAs in the BPD group was significantly higher compared to HC. Another important finding of the present study is that BPD patients' MPA-P scores do not significantly differ from those of the HC. In contrast, BPD patients' MPA-CF scores were found to be significantly higher compared to HC subjects. It is important to note that there was a low number of eligible publications included, which caused higher heterogeneity. Conclusions: Low quality of evidence suggests that MPAs are more common in patients with BPD than in HC and the higher rate of MPAs is found predominantly in the head and facial regions.

Increased Prevalence of Minor Physical Anomalies Among the Healthy First-Degree Relatives of Bipolar I Patients - Results With the Méhes Scale.

Minor physical anomalies are somatic markers of aberrant neurodevelopment, so the higher prevalence of these signs among the relatives of bipolar I patients can confirm minor physical anomalies as endophenotypes. The aim of the study was to evaluate the prevalence of minor physical anomalies in first-degree healthy relatives of patients with bipolar I disorder compared to normal control subjects. Using a list of 57 minor physical anomalies (the Méhes Scale), 20 first-degree unaffected relatives of patients with the diagnosis of bipolar I disorder and as a comparison 20 matched normal control subjects were examined. Minor physical anomalies were more common in the ear, head, mouth and trunk regions among the relatives of bipolar I patients compared to normal controls. By the differentiation of minor malformations and phenogenetic variants, we have found that both minor malformations and phenogenetic variants were more common among the relatives of bipolar I patients compared to the control group, while individual analyses showed, that one minor malformation (sole crease) and one phenogenetic variant (high arched palate) were more prevalent in the relative group. This is the first report in literature on the increased prevalence of minor physical anomalies among the first-degree unaffected relatives of bipolar I patients. The study support the concept, that minor physical anomalies can be endophenotypic markers of bipolar I affective disorder.
