Recent studies have emphasized the importance of clinical manifestations, such as insomnia and sleepiness, in defining phenotypes of obstructive sleep apnea (OSA), shifting from a focus on OSA severity and sleep structure.

The study aimed to characterize insomnia and sleepiness associated with OSA phenotypes and assess their involvement in depression symptoms (DS) in OSA.

A total of 181 participants undergoing polysomnography (PSG) were asked to fill out questionnaires, including Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Back Depression Index (BDI). They were categorized into phenotypes: insomnia-sleepiness (I+S; ESS≥11; ISI≥15; n=20), sleepiness (S; ESS≥11; ISI<15; n=22), insomnia (I; ESS<11; ISI≥15) and asymptomatic (A; ESS<11; ISI<15; n=55).

A linear regression model for BDI score (R2=0.357, p<0.001) included ISI score and subjective to objective sleep latency ratio. ISI score was a predictive factor for mild and moderate DS (OR=1.226, p<0.001 and OR=1.392, p=0.002, respectively). I and I+S phenotypes are characterized by higher BDI scores (p<0.001 and p=0.015), longer subjective sleep latency (p=0.008 and p=0.041), and shorter subjective total sleep time (TST; p=0.049 and p=0.006), compared to A. Furthermore, the I and I+S groups had shorter subjective TST than S (p=0.028 and p=0.047). I and I+S had higher BDI scores than A (p<0.001 and p=0.015, respectively) and S (p<0.001 and p=0.017, respectively). I phenotype was associated with the risk of mild and moderate DS (OR=5.614, p<0.001 and OR=9.550, p=0.008 respectively). Moreover, the I+S phenotype presented an even greater risk for mild DS (OR=10.286, p<0.001).

The study suggests that using clinical features for OSA phenotyping holds promise for finding OSA individuals with increased risk for the occurrence of DS.

Delusional parasitosis, also known as delusional infestation or Ekbom’s syndrome, is a rare psychotic disorder characterized by the false belief that a parasitic skin infestation exists, despite the absence of any medical evidence to support this claim. These patients often see many physicians, so a multidisciplinary approach among clinicians is important. Many patients refuse any treatment due to their firm belief that they suffer from an infestation, not a psychiatric condition, so it is crucial to gain the trust of these patients.

The comprehensive review of this clinical case aims to investigate Ekbom syndrome, from a historical, clinical and therapeutic perspective.

Literature review based on delusional parasitosis.

A 65-year-old woman comes to the psychiatry consultation referred by her primary care physician concerned about being infested by insects that she perceives through scales on her skin for the last three months. She recognizes important impact on her functionality. She is also convinced that her family is being infected too. As psychiatric history she recognizes alcohol abuse in the past (no current consumption) and an episode of persecutory characteristics with a neighbor, more than ten years ago. On psychopathological examination, she shows delusional ideation of parasitosis, with high behavioral repercussions, cenesthetic and cotariform hallucinations, as well as feelings of helplessness and anger. Treatment with Pimozide was started and the patient was referred to dermatology for evaluation, a plan she accepted. Her primary care physician and dermatology specialist were informed about the case and the treatment plan. In the recent reviews, the patient is calmer, however, despite the corroboration of dermatology and in the absence of organic lesions in cranial CT, she is still unsatisfied with the results, remaining firm in her conviction of infestation. It was decided to start treatment with atypical neuroleptics (Aripiprazole), with progressive recovery of her previous functionality.

Despite the increase in the number of studies in recent years, there are still few studies on this type of delirium. The female:male ratio varies in the bibiliography (between 2:1 and 3:1). The onset is usually insidious, generally appearing as a patient who comes to his primary care physician convinced of having parasites in different skin locations. It is usual to observe scratching lesions or even wounds in search of the parasite. In the past, the most used and studied treatment was Pimozide. Currently the treatment of choice is atypical neuroleptics due to their lower side effects. The latest reviews on the prognosis of this disorder show data with percentages of complete recovery between 51% and 70%, and partial responses between 16.5% and 20%. Finally, for a good diagnosis and therapeutic management, it is important to achieve a multidisciplinary approach.

Speaking prospectively we use the concept of “at risk mental state” (ARMS) to describe the state in which a person has a heightened risk of developing a psychotic disorder. Young people who are experiencing ARMS can be more precisely defined as being at ultra-high-risk of psychosis using a specific set of criteria known as the UHR criteria.

To clarify the concept of ultra-high-risk individuals and to characterize the clinical and functional characteristics and general psychopathology of those individuals that do not transition to psychosis during the follow-up period.

Research on UpToDate using the terms “Ultra-High-Risk”; “psychosis”, “transition”.

Recent literature has suggested that less than 30% of those who meet established criteria for being at Clinical-High-Risk of psychosis (CHR-P) go on to develop a psychotic illness. It is therefore of crucial importance and relevance to assess and clarify what happens to high-risk individuals who do not transition to psychosis, who make up the vast majority.

One of the most recent studies (NAPLS-2) that encompassed 764 of CHR-P individuals who were followed for 2 years, concluded that 278 did not transition to psychosis during the follow-up period. Three clinical outcomes were recorded: 1 group had experienced a psychopathological remission (39.57%); the other kept symptomatic but not currently meeting criteria for a prodromal risk syndrome (33.45%); the third group had a prodromal progression (26.98%). The study concluded among others that although the remission group had improved social functioning at 2 years compared with the other groups, they were still functioning below the healthy control group.

Another meta-analysis that included a total of 2756 CHR-P individuals with a mean duration of follow-up of 30.7 months evaluated several clinical outcomes in CHR-P that didn’t transitioned to psychosis and between CHR-P non-transitioning versus those transitioning to psychosis. It concluded that CHR-P that do not transition to psychosis have an overall improvement of symptoms (APS, negative, depressive) and functioning at follow-up compared to baseline.

The occurrence of a first psychotic episode is often devastating for the patient and their family, especially given its usual onset in adolescence and early adulthood. This is a critical period in the individual’s development as a person, and disorders at this stage can threaten the potential for a productive and inclusive adult life. Studies have suggested that less than 30% of individuals classified as UHR actually develop a psychotic disorder.

However, little is known about the individuals belonging to this group who do not transition to psychosis. We therefore consider it is relevant to clarify the clinical and functional outcomes of this group of individuals.

Millions of people have migrated because of violence, wars, disasters, and human rights violations, all of which have increased rapidly in recent years. Türkiye has hosted millions of refugees since 2010. Few studies have focused on the mental health needs of refugees or how these needs have been addressed in Türkiye.

This study examined the experiences of Syrian refugees in a community center in Turkiye as they access mental health services and receive psychiatric nursing care.

A qualitative design was adopted in the study. Data were collected from southern Turkiye between November and December 2021. The researchers conducted three semistructured focus group interviews following Colaizzi’s phenomenological method to analyze the qualitative data. A total of 19 Syrian refugees participated in the focus group interviews.

Three key themes related to immigrants’ experiences of receiving mental health services and nursing care were identified: barriers to receiving mental health services, coping with negative experiences in Turkiye, and satisfaction with mental health services. The participants identified the barriers they experienced while receiving health services as those pertaining to language, discrimination, and stigmatization. They also mentioned the methods of coping with these negative experiences in Turkiye. Despite their negative experiences, they expressed satisfaction with the mental health services they received, especially psychiatric nursing care.

This study determined that Syrian refugees face barriers to accessing and receiving mental health services. They stated that mental health professionals in Turkiye approach them with empathy, particularly those in psychiatric nursing. Healthcare professionals may be trained in culturally sensitive care to increase awareness. Studies have frequently examined the experiences of nurses providing care to refugees, but few have focused on evaluating nursing care from the perspective of refugees. Syrian refugees have reported various obstacles in accessing and receiving mental healthcare services. Health professionals, especially psychiatric nurses in mental health psychosocial support centers, must facilitate the processes to eliminate these obstacles.

Differences in psychiatry training vary substantially across Europe. Such organisations as the European Federation of Psychiatry Trainees (EFPT), the European College of Neuropsychopharmacology, and the European Psychiatry Association, have committed to offer international experiences based on the premise that it could foster international collaboration, aid early career professionals to progress professionally and spark discussion regarding different practices across Europe. To date, there are no studies that focus exclusively on the exchange experience in mental health professionals

I present the synthesis of the ten years answers from 2012 to 2022 to the post-exchange online evaluation form, which trainees had to fill in in order to receive an attendance certificate.

The present study analysed the answers of 202 psychiatry trainees or recent graduates who took part in the EFPT exchange program during 2012 and 2022 and filled in the internet-based evaluation form. The inclusion criteria were currently in training or recently finished training as a psychiatrist in Europe and filling in the questionnaire. The exclusion criterion was participation in the EFPT exchange program for the second or subsequent time.

All trainees were systemically asked to complete the online evaluation form after the exchange period. The form includes sociodemographic, training in host country-related, and exchange experience-related questions. Experience measures were evaluated using the 4-point Likert scale. Data was anonymized before the analysis. The study followed the principles of the Declaration of Helsinki.

The majority of participants were females in the second half of their training. The average age was 29 years. The largest number of applicants were from Turkey, whereas the United Kingdom hosted the most participants. One-third of the participants had previous international exchange experience. Most trainees were exposed to both outpatient and inpatient treatment settings and were involved in educational or research activities. 96.7% of participants indicated that they were satisfied or very satisfied with the experience, 95.6% said that the exchange was useful or very useful, and 98.9% were likely or very likely to recommend exchange to colleagues.

To my knowledge, this study is the first to assess the experience of psychiatry trainees who went on exchange during their professional training. Vast majority of trainees were satisfied with their exchange, thought it would be useful for their clinical practice and would recommend it to their colleagues. These findings are in line with other studies that examined medical exchange experiences .

POTION is an EU funded project (No. 824153) within the Horizon2020 initiative that aims at understanding the nature of chemosignals in humans and their sphere of influence on social interaction. The emotional state of one person can be transmitted to another through volatile molecules contained, for example, in the sweat. These molecules, or chemosignals, are processed by the receiver who is not only able to identify the feelings of the sender but also to respond accordingly.

Whitin this project, we conducted a study with the aim of exploring the possible catalyst effects of body odour on social anxiety. We hypothesized that subjects exposed to human chemosignals, while undergoing mindfulness treatment, would show an enhanced reduction in anxiety symptoms in comparison to the control group (exposed to clean air).

To this aim, a study including 96 women aged between 18 and 35 years with symptoms of social anxiety was conducted. Ater recruitment, subjects were randomly allocated to one exposure group (happiness, fear or neutral human body odour or clean air) and followed a mindfulness intervention while being exposed to one of the odour or clean air. The same intervention was repeated twice, over two consecutive days. The main outcome was change in the State-Trait Anxiety Inventory (STAI) scores for which data was collected before and after treatment at each day. Mixed model analysis revealed significant changes in STAI scores in all groups during both days of trial. However, a greater decrease in anxiety symptoms was observed in subjects exposed to fear chemosignals during both days. A post-hoc comparison of the group exposed to clean air and the group exposed to fear chemosignals showed a trend level time x odour interaction during the second day of trial (F(1,45)=3.74, p=0.07).

In conclusion, our pilot study indicated a potential use of human body odours as a catalysts of social anxiety treatment. While the small sample size restricts the generalizability of our findings, the observed trends offer a promising foundation for future research.

Work in the severe conditions of the pandemic has become a risk factor for the deterioration of the medical workers’ psychological state, which together can lead to professional burnout and, as a consequence, to professional mistakes (Pervichko, Konyukhovskaya, 2020).

The aim of the research was to study the connection between personal factors of medical workers and professional burnout during the COVID-19 pandemic.

The degree of professional burnout was assessed using Maslach Burnout Inventory (MBI) (Maslach, 2000; Vodopianova, Starchenkova, 2008), HEXACO Personality Inventory (short version) was used to study personality traits (Ashton, Lee, 2007; Egorova, et al., 2019).

The study was conducted from May 2020 to October 2022. The sample consisted of 197 medical workers (32 men and 165 women), whose average age was 38.85±12.05.

Honesty as a personality trait is negatively significantly associated with emotional exhaustion (r=-0.268, p=0.000), depersonalization (r=-0.323, p=0.000) and positively associated with a smaller reduction in professionalism (r=0.290, p=0.000). Emotionality in medical workers is positively significantly associated with emotional exhaustion (r=0.358, p=0.000) and depersonalization (r=0.243, p=0.001) and with a greater reduction in professionalism (r=-0.380, p=0.000). Extroversion is negatively associated with emotional exhaustion (r=-0.478, p=0.000) and depersonalization (r=-0.376, p=0.000) and positively associated with a smaller reduction in professional achievements (r=0.566, p=0.000). Benevolence and conscientiousness reveal negative associations with depersonalization (r=-0.248, p=0.001; r=-0.180, p=0.012) and positive associations with a smaller reduction in professionalism (r=0.190, p=0.008; r=0.301, p=0.000).

Thus, the state of emotional exhaustion during burnout is associated with greater emotionality, less honesty and extroversion. Whereas depersonalization and a greater negative assessment of one’s own professional competence and productivity is associated with less honesty, more emotionality, less extroversion, benevolence and consciousness.

Older individuals constitute a significant portion of the population, and concerted efforts are underway to enhance the quality of this life stage by minimizing health issues and maximizing opportunities.

This study aims to investigate the impact of psychosomatic exercises, including practices like yoga, meditation, and tai chi, as an alternative approach to promoting healthy aging and ultimately enhancing the quality of life among elderly individuals.

The study comprised 84 participants, with 51 individuals engaging in various forms of psychosomatic exercises and 33 serving as the control group, having no prior exposure to such practices. Data collection was carried out electronically, with the initial section gathering socio-demographic information and health-related details about the participants. The second part consisted of the WHOQOL-BREF quality of life scale, consisting of 26 questions, which assessed six domains: Overall Quality of Life and General Health, Physical Health, Psychological Health, Social Relationships, and Environment. Statistical analysis was performed with SPSS 26.

The average age of the participants was 66.7 years. A statistically significant positive correlation was identified within the first subscale of the tool, “Overall Quality of Life and General Health,” with scores of 74.3/100 for those engaging in psychosomatic exercises and 66.7/100 for those who did not (t(82) = -2.513, p = 0.014). However, no statistically significant differences were observed in the remaining subscales.

Psychosomatic exercises, including yoga, meditation, and tai chi, hold promise as a means to improve the overall quality of life and general health of elderly individuals. These practices could serve as valuable components of strategies aimed at promoting healthy aging. Further research is needed to explore their effects in greater detail and across various dimensions of well-being.

Major depressive disorder (MDD) is a common multifactorial disorder, but the exact pathophysiology is still unknown. in vivo and post-mortem studies document volumetric and cellular changes in the hippocampus of depressed patients. Chemical synapses are key functional units of the central nervous system and earlier studies found reduced number of synapses in the prefrontal cortex of depressed patients (Kang HJ et al. Nature Medicine 2012;18(9):1413-1417). Mitochondria are intracellular powerhouses generating chemical energy for cellular biochemical reactions. Recent findings suggest that individuals with impaired mitochondrial function may be vulnerable to develop psychopathologies.

We investigated synapses and mitochondria in post-mortem hippocampal samples from psychiatric patients.

The three study groups were: 1) MDD patients (n=11); 2) patients with alcohol dependence (n=8) and 3) controls (n=10). Controls were individuals who accidentally deceased and had no neuropsychiatric disorders. Three sub-regions of the hippocampus (dentate gyrus, CA3 and CA1 areas were investigated. Ultrathin sections were examined, and photomicrographs were taken for further analysis using a JEOL JEM 1400 FLASH transmission electron microscope. Systematic quantitative analysis was conducted with the Neurolucida system using unbiased counting principles.

We could not detect any differences in synapse and mitochondria densities between the patients and controls subjects.

Our preliminary data suggest that despite our expectations hippocampal synapse and mitochondrial densities are rather constant parameters which are not easily affected by psychopathology or alcohol consumption. Potential methodical limitations may also explain this negative finding.

An important aspect in providing effective psychiatric care and treatment is the formation of an adequate perception of their mental disorder in patients and awareness of the need for treatment, especially at the initial stages of the disease. Patients’ misunderstanding of their own psychopathological manifestations can act as a serious obstacle to their compliance and lead to an increase in the frequency of exacerbations and repeated hospitalizations.

To assess the attitude to the disease and treatment in patients with various mental disorders at the initial stages of the disease.

Clinical and psychopathological, psychological, statistical. The following scales were used: Drug Attitude Inventory (DAI, Hogan T.P. et al., 1983); Insight Scale for Psychosis (ISP, Birchwood M., 1994); Questionnaire “Style of self-regulation of behavior” (SSPM, V.I. Morosanova, 1988) and others. 17 patients with a diagnosis of bipolar disorder (BD, F31.xxx, ICD-10) were examined, the average age of patients was 25.52±4.55 years and 39 patients with a diagnosis of schizophrenia (F20.1xx and F23.1xx, ICD-10), the average age of patients was 29.29±9.71. The duration of the disorder in both groups of patients was 0.5-3 years.

A comparative analysis of the average scores of the scale of attitude to the disease revealed significant differences in the groups (p≤0.01). Patients with schizophrenia had a lower awareness of their disease (2.31±0.91 points) than patients with bipolar disorder (3.59±0.76 points). Correlation analysis revealed reliable connections (p≤0.01) between the scales of attitude to the disease and drugs and the self-regulation questionnaire. In patients with schizophrenia, deeper violations were found in the links of self-regulation, such as programming and planning when assessing the presence of a mental disorder and deterioration of their condition due to discontinuation of medication (r=0.38 and r=0.36, respectively). The low level of self-regulation in general and the rigidity of negative attitudes in awareness of the disease and the need for treatment also have a negative impact on compliance with the medication regimen. No such correlations were found in patients with bipolar disorder: they were more aware of the presence of a mental disorder and the need for treatment, but the degree of compliance with the medication regimen was not high enough.

The treatment of patients with mental disorders requires an integrated approach with the mandatory inclusion of a psychoeducational component in order to form an adequate model of their disease and an understanding of the expected risks when therapy is discontinued. Psychoeducation is especially relevant in the early stages of the disease, both for patients with schizophrenia and with BD.

Suicidal behaviors are frequently observed among patients with substance use disorder, including suicidal ideation (SI) (1). Alcohol use disorder (AUD) is one of the most prevalent addictions and may be related to suicidal behaviors (2,3). However, the association between AUD and SI requires a deeper analysis which includes several clinical features observed among AUD patients.

To analyze the clinical characteristics and features associated with lifetime SI among patients who had AUD.

This is a cross-sectional study performed in an outpatient center for addiction treatment in patients seeking treatment who met the criteria for AUD between 01/01/2010 and 12/31/2021. Patients were evaluated with an ad-hoc questionnaire and the European addiction severity index (EuropASI). SI was evaluated by using the item for SI in EuropASI.

From a potential sample of n=3729 patients, only n=1082 (73.8% males; mean age 42.82±12.51) met inclusion criteria and had data for the current analysis. Lifetime SI was present in 50.9% of the AUD patients. Several clinical features were related to SI, including: sex differences, any type of lifetime abuse, polyconsumption, benzodiazepine use disorder, any psychiatric diagnosis aside of SUD, and higher addiction severity according to the EuropASI (See table)

Image:

SI among AUD patients is related to several clinical features which indicate a higher addiction severity, more polyconsumption, and a higher prevalence of psychiatric comorbidities. These findings may contribute to the understanding of suicidal behaviors in AUD patients but it is required further investigations, including longitudinal studies.

Mental health reform represents one of the most transformative changes in the field of healthcare, as it not only changes the forms of services but also the nature of services offered. While many countries have successfully implemented such reforms, others, including Georgia, have struggled with a protracted and inconsistent process. Despite decades of advocacy by professionals for deinstitutionalization and the development of community-based services, psychiatric hospital treatment continues to dominate in Georgia.

The purpose of the review is to explore the concept of deinstitutionalization within the mental health landscape and assess its status in the context of Georgia. It aims to study the lessons learned from successful deinstitutionalization and illuminate achievements and challenges surrounding deinstitutionalization in Georgia’s reality.

A qualitative analysis including desk review, in-depth interviews and focus group discussions was conducted. Proceeding from the research objectives we analyzed the existing legislation, strategic documents and clinical practices concerning individuals with mental disorders; Interviews were also conducted with key informants on the shortcomings and problems in deinstitutionalization practices

The review findings reveal, that despite recent progress such as the development of community mobile teams and increased funding allocated for community services within mental health budget, several issues persist: there is no agreement among stakeholders on how to restructure existing hospital beds and financial provisions remain unresolved. The field of mental health in Georgia suffers from a lack of human resources. Attracting new personnel, ensuring regional distribution, and enhancing qualifications are necessary components of deinstitutionalization that require the involvement of all stakeholders, coordinated and time-planned action. The current mental healthcare system in Georgia is characterized by a lack of coordination and collaboration among its various components. Establishing patient care pathways with clear referral criteria is crucial for improving the efficiency of mental health services. This research highlights that successful deinstitutionalization requires additional funds, time, and trained people. Institutions should have a long-term (3-5) year development plan, detailing the source of funding, activities to be implemented, and expected outcomes. In the absence of such a plan, progress remains sporadic, intermittent, uncoordinated, and less effective.

In conclusion, the protracted nature of deinstitutionalization in Georgia requires a multifaceted approach involving various stakeholders. By addressing identified challenges and promoting coordination among mental health components, Georgia can guide a more effective course toward a community-based, patient-centered mental healthcare system.

Self-injurious behavior (SIB) among adolescents has become a hot topic in psychiatry. Despite the consensus that the prevalence of SIB is high, 26-22% among adolescence, there are conflicting results about whether it has increased in the 21st century and about the global distribution of the prevalence.

The aim of the current study was to make a systematic search and meta-analysis of publications from the last 5 years on the prevalence of SIB in adolescents and to examine definitions and assessments of SIB, gender, continental, and year differences. The hypotheses were the following: 1) the prevalence of SIB did not change over time between the examined period for both girls and boys; 2) girls reported a higher prevalence of a history of SIB than boys.

The systematic search was made in June 2020. Six databases were used. The main search terms were “self-injurious behavior”, “prevalence” and “adolescence”. First the titles and abstracts of the relevant articles were checked, then the full texts were read and collected those papers that met the inclusion criteria. The inclusion criteria were the following: published between 01/01/2015, and 06/18/2020, focused on community sample, and written in English. Comprehensive Meta-Analysis software was used to conduct the analyses.

In sum, a total of 97 articles were included in the meta-analysis with data from 439 818 participants. The overall average SIB prevalence was 16.0% in these studies. The first hypothesis was only partially confirmed. When all data that were published between 2015 and 2018 were considered, x significant increase was found in the prevalence of SIB between 1998 and 2018. However, when the analysis was restricted to the time frame between 2013 and 2018, no change in prevalence was found. The second hypothesis was fulfilled, girls reported a significant higher prevalence than boys (19.4% and 12.9%, respectively). A significantly higher prevalence was found when suicidal intent was excluded (18.3%), than when it was not excluded (11.3%) from the definition of SIB. The largest prevalence was found when measurement instruments were used that had been validated for SIB (18.9%). A significantly higher SEB prevalence was found among Asian articles than those from other continents (19.5% and 14.7% respectively).

The current systematic review and meta-analysis draw attention to the high prevalence of SIB among adolescents, especially among girls and those living in Asia. It is important to address this behavior, in terms of prevention and intervention as well.

Major depressive disorder (MDD) is a prevalent and disabling condition. Approximately 30-50% of patients do not respond to first-line medication or psychotherapy. Therefore, several studies have investigated the predictive potential of pretreatment severity rating or neuroimaging features to guide clinical approaches that can speed optimal treatment selection.

To evaluate the performance of 1) severity ratings (scores of Hamilton Depression/Anxiety Scale, illness duration, and sleep quality, etc.) and demographic characteristic and 2) brain magnetic resonance imaging (MRI) features in predicting treatment outcomes for MDD. Second, to assess performance variations among varied modalities and interventions in MRI studies.

We searched studies in PubMed, Embase, Web of Science, and Science Direct databases before March 22, 2023. We extracted a confusion matrix for prediction in each study. Separate meta-analyses were performed for clinical and MRI studies. The logarithm of diagnostic odds ratio [log(DOR)], sensitivity, and specificity were conducted using Reitsma’s random effect model. The area under curve (AUC) of summary receiver operating characteristic (SROC) curve was calculated.

Subgroup analyses were conducted in MRI studies based on modalities: resting-state functional MRI (rsfMRI), task-based fMRI (tbfMRI), and structural MRI (sMRI), and interventions: antidepressant (including selective serotonin reuptake inhibitors [SSRI]) and electroconvulsive therapy (ECT). Meta-regression was conducted 1) between clinical and MRI studies and 2) among modality or intervention subgroups in MRI studies.

We included ten studies used clinical features covering 6494 patients, yielded a log(DOR) of 1.42, AUC of 0.71, sensitivity of 0.61, and specificity of 0.74. In terms of MRI, 44 studies with 2623 patients were included, revealing an overall log(DOR) of 2.53. The AUC, sensitivity, and specificity were 0.89, 0.78, and 0.75.

Studies using MRI features had a higher sensitivity (0.89 vs. 0.61) in predicting treatment outcomes than clinical features (P < 0.001). RsfMRI had higher specificity (0.79 vs. 0.69) than tbfMRI subgroup (P = 0.01). No significant differences were found between sMRI and other modalities, nor between antidepressants (SSRIs and others) and ECT. Antidepressant studies primarily identified predictive imaging features in limbic and default mode networks, while ECT mainly focused on limbic network.

Our findings suggest a robust promise for pretreatment brain MRI features in predicting treatment outcomes in MDD, offering higher accuracy than clinical studies. While tasks in tbfMRI studies differed, those studies overall had less predictive utility than rsfMRI data. For MRI studies, overlapping but distinct network level measures predicted outcomes for antidepressants and ECT.

Lithium is an important treatment option for individuals with mood disorders, but its use has been linked to the development of chronic kidney disease (CKD). Existing studies on this association have reported conflicting results.

The aim of this study was to examine the risk of developing CKD with lithium use adjusting for common comorbidities.

This was a retrospective cohort study that included all individuals in Iceland receiving lithium therapy between 2008 and 2018. Lithium use was defined as at least one dispensed prescription for Lithium or at least one serum lithium concentration above the detection limit. Patients with affective disorders (ICD-10 codes F30-F39) attending the outpatient clinics of Landspitali–The National University Hospital Mental Health Services in 2014-2016, without lithium exposure, served as controls. CKD stages 3-5 were defined according to the Kidney Disease Improving Global Outcomes (KDIGO) guidelines for CKD as estimated glomerular filtration rate (eGFR) less than 60 mL/min/1.73 m2. The eGFR was calculated using the serum creatinine (SCr) based on the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Acute kidney injury (AKI) was defined according to the SCr component of the KDIGO criteria for AKI, and other comorbid diseases were defined based on ICD-9 and ICD-10 codes. Individuals with fewer than 2 SCr measurements during the study period and those with CKD stages 3-5 prior to 2008 were excluded. Cox regression analysis with time dependent variables was performed to assess the risk of CKD.

The study included 2046 individuals exposed to lithium, of whom 221 (10.9%) developed CKD in the study period. Among the 1220 control subjects, 39 (3.2%) developed CKD. Lithium use was associated with CKD (hazard ratio [HR] 1.93, 95% confidence interval [CI] 1.37–2.74) after adjusting for sex, age, and comorbid diseases. Other significant risk factors were age (per year, HR 1.03, 95% CI 1.02–1.04), initial eGFR (per mL/min/1.73 m2, HR 0.92-0.96, 95% CI 0.90–0.99), presence of diabetes (HR 1.73, 95% CI 1.15–2.48) and history of AKI (HR 1.89, 95% CI 1.32–2.70). When compared to the control group not exposed to lithium, the risk (HR) of CKD was 1.24 (95% CI 0.81–1.89), 2.88 (95% CI 1.97–4.20) and 5.23 (95% CI 3.31-8.26) for groups with a mean lithium concentration of 0.3-0.59, 0.6-0.79 and 0.8-0.99 mmol/L, respectively.

Long-term lithium therapy seems to increase the risk of CKD in a concentration-dependent manner in individuals with bipolar and unipolar mood disorders. To mitigate this risk, it is essential to monitor blood levels carefully and use doses of lithium as low as possible for adequate mood stabilization and treatment.

Exercise can be considered a feasible and efficient add-on treatment in schizophrenia. However, there remain two major challenges with regard to feasibility and efficiency: First, drop-out rates during exercise programs appear to be relatively high, ranging between 30 to 80 percent. Second, only between 30 and 50 percent of patients clinically respond to exercise interventions. Hence, we aimed to identify factors that predict adherence and response to exercise programs in people with schizophrenia. Based on data from 180 patients with schizophrenia enrolled in the Enhancing Schizophrenia Prevention and Recovery through Innovative Treatments (ESPRIT) C3 study, we examined clinical baseline characteristics that may predict study completion and number of attended trainings (adherence), as well es clinically relevant improvements in symptomatology and functioning (response). We found that only levels of functioning at baseline, but not symptom severity, cognitive functioning, or physical health, predicted adherence. Further, we provide preliminary evidence suggesting that patients with higher cognitive abilities and higher education who performed regular exercise already prior to the study participation were more likely to respond. To conclude, our findings indicate that exercise is particularly helpful for a subgroup of patients characterized by higher levels of functioning, higher cognitive abilities and education, and more pronounced affinity to exercise. Future studies should additionally include environmental, genetic, and neural data to predict adherence and response to exercise.

The introduction of antipsychotics, especialy of newer generation, greatly a”ects the e”ectiveness of the psychiatric treatment of patients with schizophrenia (SCH) and bipolar disorder (BP). Patients su”ering from SCH and BP often have metabolic syndrome (MetSy), as a result of taking antipsychotic therapy, especially in patients with abdominal obesity, there is an atherogenic fat profile that carries a high risk for the development of dyslipidemia.

To investigate frequency and di”erences of somatic diseases in patients with SCH and BD depending on the presence of MetSy.

This five-year prospective study was conducted in the Psychiatric Hospital of Canton Sarajevo. We followed 135 patients with SCH and 135 patients with BD, aged 30 to 69 years, who were treated with antipsychotics for five years.

Dyslipidemia was significantly more common in SCH patients (73.3%), compared to BD (54.1%) and was dominantly presented in women (61.4%). The frequency of dyslipidemia increased with the age of the patient. Associated risk factors in patients with SCH diagnosed with dyslipidemia were 73.5% smokers, 78.7% hypertensive patients, 69.7% patients with elevated BMI and 83.0% with elevated blood glucose values, while slightly lower values were recorded patients with BP. 97.8% of patients with dyslipidemia had elevated CRP.

There are significant di”erences in dyslipidemia in patients su”ering from SCH and BP. Adequate knowledge of the antipsychotic drugs is required in order to provide adequate psychiatric treatment, regarding minimalising adverse e”ects of antipsychotics will be reduced to a minimum. It is important to recognize high-risk patients and educate them about preventive measures.

Early diagnosis and intervention are essential for managing and improving long-term outcomes of severe mental illness, highlighting the need for reliable early biomarkers. This longitudinal study explores whether the development of the brain during childhood and adolescence differs between offspring of parents with and without schizophrenia or bipolar disorder. Moreover, we will assess if the age-dependent change over time in brain volume, cortical thickness and surface, structural network indices, and cortical gyrification are related to the presence and severity of psychiatric symptoms and level of IQ.

We obtained 286 T1-weighted MRI scans of 184 offspring (aged 8–18 years at baseline) of at least one parent diagnosed with bipolar disorder (n=78) or schizophrenia (n=52) and offspring of parents without severe mental illness (n=54); 102 offspring underwent a follow-up scan (on average 3.9 years between scans).

Group comparisons and the associations with clinical and cognitive measures were analysed with linear mixed-effects models. To correct for multiple comparisons, we applied a Benjamini-Hochberg false discovery rate (FDR) correction (q=0.05).

A significant effect of age was found on most of the included brain features, with suggestive evidence for subtle deviations in trajectories in the cortical thickness, structural network indices but not in gyrification index, sulcal depth, length and width or surface area in offspring of parents with schizophrenia. Interestingly, these deviations in brain development in schizophrenia offspring remained significant after taking the presence of a diagnosis or level of IQ into account. These findings suggest the aberrant brain development in familial high-risk youngsters is associated with being at familial risk and not with (also) being at clinical high-risk.

Suicide is one of the leading causes of death worldwide being the fourth major cause of death among young people 15-29 years old. The reduction of suicide mortality is prioritized by the World Health Organization (WHO, 2019). There is a number of internal and external factors associated with suicidality (Soto-Sanz V et al., 2019; Farbstein et al., 2022.). Special attention is paid to the influence of the social media on suicidality (Cheng A. T. A. et al., 2007; Niederkrotenthaler T. et al., 2020; Sedgwick R. et al., 2019). In the Russian Federation, anime, an animation genre and a media cultural phenomenon, is increasingly popular among young people. Characters who are lonely and lost their meaning of life are common in anime. Romanticization and idealization of such characters may lead to increased attractiveness of death and thus have a negative effect on the mental health of adolescents and young adults due to their incomplete identity development (Liu Y. et al., 2022; Backer, H. A., 2023).

We aimed to study the influence of the anime on the presence of suicidality and depression in adolescents and young adults in the Russian Federation.

We interviewed 304 people living in the Russian Federation and watching anime on the regular basis (244 women, mean age 20.9 ± 3.8 years, range 13-36 years). We collected sociodemographic data and age when a person had started watching anime. We performed Reasons for Living Inventory, RFL (M. Linehan et al., 1983), Beck Depression Inventory, BDI (Aaron Beck, 1961). We divided all participants into three groups according to their age: adolescents (13-19 years), young people (20-24 years), adults (25-36 years). In each group, we compared BDI: level of depressive symptoms, cognitive-affective subscale, subscale of somatic manifestations of depression; RFL scales: Survival coping beliefs, responsibility to family, child related concerns, fear of suicide, fear of social disapproval, moral objections between three subgroups based on the age of the anime watching start (<12 years old, 12-15 years old, ≥16 years old) using Kruskall-Wallis test and post hoc Mann-Whitney U-test for pair comparisons with Bonferroni correction for multiple comparisons. Level of significance p<0.05.

In the adolescents (n=130), we did not find any differences between the three subgroups. In the young people (n=127), participants who had started watching anime in childhood (<12 years old) had higher level of depression (p= 0,014) and higher level of cognitive-affective symptoms (p= 0,006). In the adults (n=47), participants who had started watching anime in childhood had decreased moral attitudes contrary to suicide (p= 0,004). Other scales not found to differ significantly.

Start of the anime watching in childhood (<12 years old) was associated with increased suicidal risk factors and decreased anti-suicidal factors in the young adults.

In large cities around the world, many sources of noise including traffic, domestic, construction, and industrial activities, contribute to urban noise pollution, which is now, a major concern in public health as declared by the WHO, for more than a decade (in 2011).

The aim of this study was to try to find potential recommendations and references in terms of urban planning, particularly with the emergence of smart cities, to combat the problem of noise pollution and related mental health hazards.

We conducted a comprehensive review of the scientific literature using the following keywords: cities, smart cities, noise, pollution and mental health.

Our research found that the continuous exposure to high noise levels could lead to psychological and physiological problems, such as hearing disorders, high blood pressure, heart disease, inconvenience and sleep disorders. While recent evidence indicates that road traffic noise has a negative impact on mental health and that aircraft noise significantly increases the risk of depression, there are not enough studies to date to properly assess the relationship between urban noise pollution and mental health hazards such as anxiety, mood disorders, sexual disturbance, cognitive impairment, learning disabilities, dementia, etc. In the field of urban planning, there is also a lack of reliable data on individual exposure to environmental noise in space and time, and on its effects on mental health.

Various noise mitigation strategies in urban renewal plans are proposed, such as the implementation of noise mapping to provide the detailed spatial distribution of noise levels in urban areas, their sources and time intervals, noise barriers along traffic arteries, vegetation and landscaping. New infrastructure projects involving new expressways and high-speed trains as well as the widening of major roads in their central areas are also suggested.
