ABSTRACT

Introduction: Cognitive rehabilitation is essential for schizophrenia treatment since it improves function. Moreover, the relationship between cognitive rehabilitation and functioning is significantly affected by negative symptoms and social cognition. Integrated Psychological Therapy (IPT) is a promising approach that integrates interventions in neurocognition, social cognition, and functional level. This study examines IPT's efficacy in chronic middle-aged inpatients. Methods: A randomized controlled study involved 44 individuals with schizophrenia. Twenty-one IPT participants received 50 biweekly sessions and medication, while twenty-three control participants received treatment as usual/supportive therapy and pharmacotherapy. Pre- and post-intervention and six- and twelve-month follow-ups were arranged to assess neurocognition, social perception, psychopathology, and functioning using the Matrics Consensus Cognitive Battery, Social Perception Scale, Positive and Negative Syndrome Scale, and Global Assessment of Functioning. Results: Speed of processing, attention/vigilance, overall composite, and neurocognitive composite scores improved significantly in the IPT group. Social Perception Scale performance improved in all areas after the intervention and persisted for 6 months. Positive, negative, and total psychopathology symptoms decreased significantly post-intervention and at the 12-month follow-up, whereas participants' functioning improved significantly. Conclusions: Middle-aged chronic inpatients with schizophrenia may benefit from IPT in neurocognition, social perception, psychopathology, and functioning. This field of study may provide insight into schizophrenia treatment, hence further research is encouraged.

ABSTRACT

A considerable proportion of patients with schizophrenia perform below population norms on standardized neuropsychological tests, and the performance of those performing within normal range is lower than predicted based on parental education. Cognitive impairment predates the onset of psychosis, is observed during symptom remission and in non-affected first-degree relatives of patients. At the present time, cognitive deficits are regarded as key features of schizophrenia, important determinants of poor psychosocial outcome and targets for both pharmacological and non-pharmacological treatment strategies. A group of eight key opinion leaders reviewed and discussed latest advances in scientific research and current good clinical practices on assessment, management, and treatment of CIAS. In the present paper they summarize the current evidence, identify main gaps between current knowledge and mental health services clinical practice, and provide practical recommendations to reduce the gap.

ABSTRACT

Background: Schizophrenia spectrum and other psychotic disorders (SSPD) are among the most debilitating of all mental disorders. While the evidence for psychosocial interventions such as cognitive behavioral therapy and peer support has significantly improved, access to these services remains limited. This paper describes a protocol for a pragmatic feasibility study of a digital mental health intervention (HoryzonsCa) that provides access to evidence-based psychosocial interventions, social networking, and clinical and peer support services through a secured, web-based platform for adults diagnosed with SSPD. Objective: The objectives are: (1) Adapt and translate HoryzonsCa for implementation in English and French; (2) Develop an implementation and training strategy; (3) Assess the acceptability, safety, and demand of HoryzonsCa; (4) Assess clinical outcomes and perceived impacts; (5) Examine the experiences and process of adapting and implementing HoryzonsCa; (6) Explore the role of sociocultural and demographic factors on HoryzonsCa outcomes and implementation. Methods: This feasibility study will use a single-group, pre-post, mixed-methods (QUAN-QUAL convergent) research design, with assessments at baseline and 12 weeks. The study aims to recruit 100 individuals (ages 18-50) diagnosed with SSPD from two healthcare settings in Canada. Data collection includes interview-based psychometric measures, self-reports, focus groups, and interviews with participants. The study will also collect qualitative data from moderators and the research team, and will be conducted entirely remotely. Conclusions: This study has been prospectively registered and is underway. It will provide timely information on the feasibility and potential impacts of using digital mental health services for individuals with chronic mental health conditions.

ABSTRACT

BACKGROUND: Benzodiazepines and electroconvulsive therapy (ECT) are mainstay treatments for catatonia, a potentially life-threatening psychomotor syndrome characterized by a range of symptoms, including immobility, mutism, stupor, posturing, and sometimes even agitation. It can be a manifestation of various underlying psychiatric or medical conditions, such as schizophrenia, mood disorders, or neurological disorders. When conventional treatments fail to alleviate symptoms, ketamine, a dissociative anesthetic, has emerged as a potential therapeutic option for catatonia. However, its precise mechanism of action in treating catatonia remains to be fully elucidated. The use of ketamine in treating treatment-resistant catatonia in patients with schizophrenia has not been described. METHODS: We describe a unique case of a 77-year-old female with schizophrenia for 15 years who presented with hallucinations, generalized weakness, immobility, stupor, and mutism consistent with severe catatonia. The electroencephalogram did not show seizures, and brain imaging was negative for stroke. Her catatonia was resistant to treatment with benzodiazepines and haloperidol. However, ECT was unavailable due to the COVID-19 pandemic. She was successfully treated with a single intravenous infusion of ketamine administered at a dose of 0.5 mg/kg over 40 min with complete rapid recovery and remained stable as an outpatient. RESULTS: Intravenous ketamine single infusion may be a safe and feasible option in schizophrenia patients with drug-resistant catatonia, particularly in patients for whom standard therapies are ineffective. However, its use should be approached cautiously due to the risk of exacerbation of psychosis in patients with schizophrenia. CONCLUSIONS: Further research is warranted to better understand the role of ketamine in the management of catatonia in this patient population.

ABSTRACT

BACKGROUND: Evidence regarding schizophrenia relapse following acute electroconvulsive therapy (ECT) is sparse compared with that for depression, and we have no clear consensus on relapse proportions. We aimed to provide longitudinal information on schizophrenia relapse following acute ECT. STUDY DESIGN: This systematic review and meta-analysis included randomised controlled trials (RCTs) and observational studies on post-acute ECT relapse and rehospitalization for schizophrenia and related disorders. For the primary outcome, we calculated the post-acute ECT pooled relapse estimates at each timepoint (3, 6, 12, and 24 months post-acute ECT) using a random effects model. For subgroup analyses, we investigated post-acute ECT relapse proportions by the type of maintenance therapy. STUDY RESULTS: Among a total of 6413 records, 29 studies (3876 patients) met our inclusion criteria. The risk of bias was consistently low for all included RCTs (4 studies), although it ranged from low to high for observational studies (25 studies). Pooled estimates of relapse proportions among patients with schizophrenia responding to acute ECT were 24% (95% CI: 15-35), 37% (27-47), 41% (34-49), and 55% (40-69) at 3, 6, 12, and 24 months, respectively. When continuation/maintenance ECT was added to antipsychotics post-acute ECT, the 6-month relapse proportion was 20% (11-32). CONCLUSION: Relapse occurred mostly within 6 months post-acute ECT for schizophrenia, particularly within the first 3 months. Relapse proportions plateaued after 6 months, although more than half of all patients could be expected to relapse within 2 years. Further high-quality research is needed to optimise post-acute ECT treatment strategies in patients with schizophrenia.

ABSTRACT

Although aberrant static functional brain network activity has been reported in schizophrenia, little is known about how the dynamics of neural function are altered in first-episode schizophrenia and are modulated by antipsychotic treatment. The baseline resting-state functional magnetic resonance imaging data were acquired from 122 first-episode drug-naïve schizophrenia patients and 128 healthy controls (HCs), and 44 patients were rescanned after 1-year of antipsychotic treatment. Multilayer network analysis was applied to calculate the network switching rates between brain states. Compared to HCs, schizophrenia patients at baseline showed significantly increased network switching rates. This effect was observed mainly in the sensorimotor (SMN) and dorsal attention networks (DAN), and in temporal and parietal regions at the nodal level. Switching rates were reduced after 1-year of antipsychotic treatment at the global level and in DAN. Switching rates at baseline at the global level and in the inferior parietal lobule were correlated with the treatment-related reduction of negative symptoms. These findings suggest that instability of functional network activity plays an important role in the pathophysiology of acute psychosis in early-stage schizophrenia. The normalization of network stability after antipsychotic medication suggests that this effect may represent a systems-level mechanism for their therapeutic efficacy.

ABSTRACT

BACKGROUND: Research on schizophrenia and life expectancy has mainly focused on premature mortality. AIMS: This study investigates factors associated with longevity in patients with schizophrenia receiving long-term care and identifies shared traits among these individuals. METHOD: A retrospective cross-sectional study analysing the clinical records of 138 patients with schizophrenia who died between 2015 and 2017 in a psychiatric long-term care facility was conducted. Longevity was defined by life tables drawn from the national health database. Variables were compared between longevity and control groups to determine predictors of longer lifespans. Cluster analysis was employed to identify shared traits among individuals with longevity. Causes of death by age were compared. RESULTS: In the long-term care setting, of the 138 participants, 45 were in the longevity group. This group had more males, lower antipsychotic doses, but more mobility issues. Significant predictors of longevity included older age at onset, longer length of stay, lower activities of daily living scores and a hypertension diagnosis. Cluster analysis revealed two patterns, suggesting that poorer health indicators did not necessarily lead to shorter lives. Fatalities caused by pneumonia were associated with a higher age, compared to those from cancer and choking. CONCLUSIONS: Addressing modifiable risk factors enhances life expectancy in patients with schizophrenia, especially for males, while the age at onset may play a significant role. An integrated long-term care model with close monitoring and timely provision of mental and general healthcare may help extend lifespans. Further research is needed to balance long-term residential care and community-based care for elderly patients with schizophrenia.

ABSTRACT

Background and objective: Peak width of skeletonized mean diffusivity (PSMD), a fully automated diffusion tensor imaging (DTI) biomarker of white matter (WM) microstructure damage, has been shown to be associated with cognition in various WM pathologies. However, its application in schizophrenic disease remains unexplored. This study aims to investigate PSMD along with other DTI markers in first-episode schizophrenia patients compared to healthy controls (HCs), and explore the correlations between these metrics and clinical characteristics. Methods: A total of 56 first-episode drug-naive schizophrenia patients and 64 HCs were recruited for this study. Participants underwent structural imaging and DTI, followed by comprehensive clinical assessments, including the Positive and Negative Syndrome Scale (PANSS) for patients and cognitive function tests for all participants. We calculated PSMD, peak width of skeletonized fractional anisotropy (PSFA), axial diffusivity (PSAD), radial diffusivity (PSRD) values, skeletonized average mean diffusivity (MD), average fractional anisotropy (FA), average axial diffusivity (AD), and average radial diffusivity (RD) values as well as structural network global topological parameters, and examined between-group differences in these WM metrics. Furthermore, we investigated associations between abnormal metrics and clinical characteristics. Results: Compared to HCs, patients exhibited significantly increased PSMD values (t = 2.467, p = 0.015), decreased global efficiency (Z = -2.188, p = 0.029), and increased normalized characteristic path length (lambda) (t = 2.270, p = 0.025). No significant differences were observed between the groups in the remaining metrics, including PSFA, PSAD, PSRD, average MD, FA, AD, RD, local efficiency, normalized cluster coefficient, small-worldness, assortativity, modularity, or hierarchy (p > 0.05). After adjusting for relevant variables, both PSMD and lambda values exhibited a significant negative correlation with reasoning and problem-solving scores (PSMD: r = -0.409, p = 0.038; lambda: r = -0.520, p = 0.006). No statistically significant correlations were observed between each PANSS score and the aforementioned metrics in the patient group (p > 0.05). Multivariate linear regression analysis revealed that increased PSMD (ß = -0.426, t = -2.260, p = 0.034) and increased lambda (ß = -0.490, t = -2.994, p = 0.007) were independently associated with decreased reasoning and problem-solving scores respectively ( R a d j 2 = 0.295, F = 2.951, p = 0.029). But these significant correlations did not withstand FDR correction (p_FDR > 0.05). Conclusion: PSMD can be considered as a valuable neuroimaging biomarker that complements conventional diffusion measurements for investigating abnormalities in WM microstructural integrity and cognitive functions in schizophrenia.

ABSTRACT

OBJECTIVES: Metacognitive training (MCT) for psychosis is a group intervention that combines cognitive-behavioural therapy and psychoeducation. It has proven efficacy in reducing psychotic symptoms and correcting cognitive biases implicated in the development and maintenance of psychotic symptoms. However, other outcomes, such as patient satisfaction with the intervention, have not been well studied despite their importance for adherence and overall success. A systematic review of randomized clinical trials was conducted to assess satisfaction with MCT among adults with psychotic spectrum disorders. METHODS: The search was conducted in Ovid Embase, Ovid MEDLINE, PsycINFO and Cochrane Central Register of Controlled Trials (CENTRAL). PRISMA guidelines and the Cochrane Risk of Bias Tool were followed, and certainty of evidence was ascertained using the Grading of Recommendations Assessment, Development and Evaluation framework. The study is registered with PROSPERO (CRD42023418097). RESULTS: Patient satisfaction was considered the primary outcome in 3 of the 10 studies reviewed. Four studies compared MCT with other psychosocial interventions (a newspaper discussion group, cognitive remediation and supportive therapy), two of which found significantly higher satisfaction with MCT. A high percentage of all patients found MCT comprehensible and considered it an important part of their treatment; they would recommend the training to others and found the group setting advantageous. Most participants expressed high subjective satisfaction or acceptance of MCT. CONCLUSIONS: The authors found evidence that MCT may be associated with high levels of satisfaction in clinical trials whose main objective is to assess patient satisfaction, but more research is needed to consolidate the findings, especially for the extended version of MCT.

ABSTRACT

Psychotropic drugs are vital in psychiatry, aiding in the management of mental health disorders. Their use requires an understanding of their pharmacological properties, therapeutic applications, and potential side effects. Ongoing research aims to improve their efficacy and safety. Biomarkers play a crucial role in understanding and predicting memory decline in psychotropic drug users. A comprehensive understanding of biomarkers, including neuroimaging, biochemical, genetic, and cognitive assessments, is essential for developing targeted interventions and preventive strategies. In this narrative review, we performed a comprehensive search on PubMed and Google using review-specific terms. Clinicians should use a multifaceted approach, including neurotransmitter analysis, neurotrophic factors, miRNA profiling, and cognitive tasks for early intervention and personalized treatment. Anxiolytics' mechanisms involve various neurotransmitter systems and emerging targets. Research on biomarkers for memory decline in anxiolytic users can lead to early detection and intervention, enhancing clinical practices and aligning with precision medicine. Mood stabilizer users can benefit from early detection of memory decline through RNA, neurophysiological, and inflammatory biomarkers, promoting timely interventions. Performance-enhancing drugs may boost athletic performance in the short term, but their long-term health risks and ethical issues make their use problematic. Long-term use of psychotropic performance enhancers in athletes shows changes in biomarkers of cognitive decline, necessitating ongoing monitoring and intervention strategies. Understanding these genetic influences on memory decline helps pave the way for personalized approaches to prevent or mitigate cognitive deterioration, emphasizing the importance of genetic screening and early interventions based on an individual's genetic profile. Future research should focus on refining these biomarkers and protective measures against cognitive deterioration. Overall, a comprehensive understanding of biomarkers in psychotropic drug users is essential for developing targeted interventions and preventive strategies.

ABSTRACT

Though theory of mind (ToM) is an important area of study for different disciplines, however, the psychometric evaluations of ToM tasks have yielded inconsistent results across studies and populations, raising the concerns about the accuracy, consistency, and generalizability of these tasks. This systematic review and meta-analysis examined the psychometric reliability of 27 distinct ToM tasks across 90 studies involving 2771 schizophrenia (SZ), 690 autism spectrum disorder (ASD), and 15,599 nonclinical populations (NC). Findings revealed that while all ToM tasks exhibited satisfactory internal consistency in ASD and SZ, about half of them were not satisfactory in NC, including the commonly used Reading the Mind in the Eye Test and Hinting Task. Other than that, Reading the Mind in the Eye Test showed acceptable reliability across populations, whereas Hinting Task had poor test-retest reliability. Notably, only Faux Pas Test and Movie for the Assessment of Social Cognition had satisfactory reliability across populations albeit limited numbers of studies. However, only ten studies examined the psychometric properties of ToM tasks in ASD adults, warranting additional evaluations. The study offered practical implications for selecting ToM tasks in research and clinical settings, and underscored the importance of having a robust psychometric reliability in ToM tasks across populations.

ABSTRACT

BACKGROUND: Cognitive impairments are a hallmark symptom of schizophrenia (SCZ). Phosphatidylethanolamine (PE) is the second most abundant phospholipid in mammalian cells, yet its role in cognitive deficits remains unexplored. The aim of this study was to investigate the association between plasma LysoPE and cognitive improvements following olanzapine monotherapy in drug-naïve first-episode (DNFE) SCZ patients. METHODS: Twenty-five female DNFE SCZ patients were treated with olanzapine for four weeks, and cognitive function was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) at baseline and after the 4-week follow-up. Utilizing an untargeted ultra-performance liquid chromatography-mass spectrometry (UPLC-MS)-based metabolomics approach, we measured LysoPE concentrations. RESULTS: Significant improvements in immediate and delayed memory domains were observed post-treatment. We identified nine differential LysoPE species after olanzapine monotherapy, with increased concentrations for all LysoPE except LysoPE (22:6). Elevated LysoPE (22:1) concentration positively correlated with cognitive improvement in patients. Baseline LysoPE (16:1) emerged as a predictive factor for cognitive improvement following olanzapine monotherapy. CONCLUSIONS: This study offers preliminary evidence for the involvement of LysoPE in cognitive improvements observed in drug-naïve first-episode SCZ patients after olanzapine treatment.

ABSTRACT

BACKGROUND: While inflammation is associated with cognitive impairment in severe mental illnesses (SMI), there is substantial heterogeneity and evidence of transdiagnostic subgroups across schizophrenia (SZ) and bipolar (BD) spectrum disorders. There is however, limited knowledge about the longitudinal course of this relationship. METHODS: Systemic inflammation (C-Reactive Protein, CRP) and cognition (nine cognitive domains) was measured from baseline to 1 year follow-up in first treatment SZ and BD (n = 221), and healthy controls (HC, n = 220). Linear mixed models were used to evaluate longitudinal changes separately in CRP and cognitive domains specific to diagnostic status (SZ, BD, HC). Hierarchical clustering was applied on the entire sample to investigate the longitudinal course of transdiagnostic inflammatory-cognitive subgroups. RESULTS: There were no case-control differences or change in CRP from baseline to follow-up. We confirm previous observations of case-control differences in cognition at both time-points and domain specific stability/improvement over time regardless of diagnostic status. We identified transdiagnostic inflammatory-cognitive subgroups at baseline with differing demographics and clinical severity. Despite improvement in cognition, symptoms and functioning, the higher inflammation - lower cognition subgroup (75% SZ; 48% BD; 38% HC) had sustained inflammation and lower cognition, more symptoms, and lower functioning (SMI only) at follow-up. This was in comparison to a lower inflammation - higher cognition subgroup (25% SZ, 52% BD, 62% HC), where SMI participants showed cognitive functioning at HC level with a positive clinical course. CONCLUSIONS: Our findings support heterogenous and transdiagnostic inflammatory-cognitive subgroups that are stable over time, and may benefit from targeted interventions.

ABSTRACT

INTRODUCTION: Despite proven effectiveness in refractory schizophrenia, clozapine remains underutilised, and it is important to understand potential reasons for this. This study's aim was to examine in a National sample of Consultant Psychiatrists their knowledge of, attitudes and perceived barriers to clozapine use. METHODS: A novel questionnaire was designed and distributed by email to 275 Consultant Psychiatrists in Republic of Ireland. RESULTS: Twenty-eight percent (n = 77) completed the survey, with 55% of respondents practicing for 15 or more years. Clinicians expressed confidence in managing clozapine treatment and side effects and were well aware of clozapine's clinical effectiveness and guideline-based use. A majority indicated insufficient experience managing rechallenge and half expressed insufficient experience managing adverse events. Perceived patient factors were highlighted as barriers with 69% of respondents reporting patients' concern about effectiveness and 50% regarding tolerability. Sixty-four percent (n = 40) indicated that a specialised/tertiary clozapine service would facilitate initiation, with 57% (n = 36) reporting less frequent blood monitoring would aid clozapine prescribing. A majority identified that access to dedicated staff (81%, n = 51) and dedicated day hospital services (84%, n = 53) would facilitate community initiation. CONCLUSION: Consultants are familiar with clozapine use and related guidelines. Dedicated staff and facilities for clozapine use is one identified structural change to enhance clozapine prescribing in Ireland. Tertiary service or clinical advice service would assist in clozapine rechallenge cases or in managing significant adverse events. More structured patient education regarding clozapine effectiveness and professional development programmes focused on managing side effects and rechallenge may promote clozapine use.

ABSTRACT

The aim of this randomized controlled trial was to examine the effect of Physical Activity Program applied to patients with schizophrenia on subjective well-being, happiness and problem-solving skills levels. This study was conducted with a total of 86 individuals diagnosed with schizophrenia (43 intervention and 43 control) registered in a family health center. Subjective Well-Being Scale, the Short Form of the Oxford Happiness Questionnaire and Problem-Solving Inventory were used to collect the data at baseline and, post-intervention. Significant increases in subjective well-being, happiness, and problem-solving skills were found in the intervention group after the total of 12 weeks of the Physical Activity Program, which included walking and exercises, compared to the control group. Accordingly, it can be said that the Physical Activity Program is an effective method that increases subjective well-being, happiness and problem-solving skills. ClinicalTrials.gov Identifier number is NCT15976921 and date of registration is 21/11/2023, retrospectively registered.

ABSTRACT

Introduction and importance: Pleomorphic xanthoastrocytoma (PXA) was first described by Kepes et al. in 1979. Fewer than 200 cases have been reported in the literature. It generally involves the temporoparietal lobe. PXA has a favorable prognosis. The most reported clinical manifestation is epileptic seizures. Revealing psychiatric symptoms have an incidence varying from 50 to 78%. The most common symptoms encountered are anxiety disorders, depression, schizophrenia-like psychosis, cognitive dysfunction or even anorexia nervosa. Case presentation: Here, the authors report a new case of non-anaplastic pleomorphic xanthoastrocytoma revealed by a drug-resistant schizophrenia-like psychosis in a 26-year-old male patient known with epileptic seizures in whom these two pathologies were intertwined and had been evolving for 5 years. The postoperative course was uneventful, and positive symptoms of schizophrenia were relatively stabilized at discharge. Clinical discussion: Given the superficial hemispheric location of PXA, the most common clinical presentation is seizures. Psychiatric symptoms revealing brain tumors have an incidence varying from 50 to 78%. Most of these symptoms concern frontal and limbal tumors. In their case, the tumor was located in the right temporal lobe. Surgery was performed and postoperative course was uneventful even though there are conflicting reports regarding the importance of the surgical excision quality. Conclusion: PXA remains a rare and benign primary CNS tumor. Psychiatric disorders represent a rare revealing mode of this pathology, which must lead to neuroimaging in any patient carrying this type of symptoms.

ABSTRACT

Schizophrenia is a chronic, severe, and disabling mental disorder that significantly impacts individuals' lives. Long-term treatment with antipsychotic drugs, coupled with the complications of the disease itself, increases the risk of dysphagia in patients. These disorders further heighten the likelihood of choking and asphyxia death among this population. This project aims to comprehensively review the pathological mechanisms behind dysphagia in schizophrenia, alongside proposing early screening and evaluation methods. It also suggests treatment recommendations to mitigate the risks and complications associated with dysphagia in these patients.

ABSTRACT

Postpartum psychosis (PP) is a rare and severe mental health disorder occurring shortly after childbirth, characterized by symptoms such as delusions, hallucinations, and intense mood swings. This review examines the potential link between PP and the later development of schizophrenia, a chronic psychiatric condition that typically emerges in late adolescence or early adulthood. By reviewing existing literature and analyzing epidemiological and clinical data, this review aims to clarify whether PP can be a precursor to schizophrenia. Findings suggest that while the transition from PP to schizophrenia is not inevitable, there is an increased risk, with some studies indicating that a subset of women with PP may develop a chronic psychotic disorder later on. This underscores the importance of early detection, ongoing monitoring, and targeted interventions. The review emphasizes the need for improved diagnostic practices and preventive measures to better manage PP and its potential long-term effects. Enhanced understanding of this relationship can inform more effective treatment strategies and support better mental health outcomes for new mothers. Future research should focus on refining risk assessment tools, exploring underlying mechanisms, and developing comprehensive management approaches to address the challenges associated with PP and its potential progression to schizophrenia.

ABSTRACT

Objective: Schizophrenia (SCZ) is a prevalent chronic mental disorder characterized by a high recurrence rate and significant disability. Currently, no satisfactory pharmacological treatments have been identified. Although Ningshen Wendan decoction (NSWDD) has shown promising results in improving cognitive function in patients with schizophrenia, its underlying mechanism of action remains unclear. Methods: This study systematically investigated the mechanisms of NSWDD in SCZ treatment using network pharmacology and molecular docking approaches. Results: Analysis of the interaction genes revealed 307 common targets of NSWDD and SCZ. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses indicated the involvement of multiple signaling pathways including interleukin 17 signaling pathway, multiple virus infections, Advanced glycosylation end products (AGEs) - receptor of AGEs (AGEs-RAGE) signaling pathway, tumor necrosis factor signaling pathway, and Hypoxia-inducible factor-1 (HIF-1) signaling pathway as key pathways influenced by NSWDD in treating SCZ. These pathways are associated with various biological processes such as transcriptional regulation, apoptosis regulation, gene expression regulation, and external stimulus-response. Molecular docking simulations indicated favorable binding interactions between components of NSWDD and target proteins via intermolecular forces. Conclusion: The study provided initial insights into the internal molecular mechanisms underlying the beneficial effect of NSWDD on SCZ through multi-target modulation across multiple pathways.

ABSTRACT

BACKGROUND: Emotion processing (EP) is impaired in individuals with psychosis and associated with social functioning; however, it is unclear how symptoms fit into this relationship. The aim of this systematic review and meta-analysis was to examine interrelationships between EP, symptoms, and social functioning, test whether different symptom domains mediate the relationship between EP and social functioning, and examine the moderating effects of illness stage and EP task type. STUDY DESIGN: MEDLINE, Embase, and PsycINFO databases were searched for studies that included individuals with psychosis and reported correlations between EP, symptom domains (positive, negative, depressive, and disorganization), and social functioning. Random effects meta-analyses determined the strength of correlations, and subgroup analyses included illness stage and EP task type (lower- vs higher-level processing). Meta-analytic structural equation models tested whether symptom domains mediated the relationship between EP and social functioning. RESULTS: There was a small relationship (r = .18) between EP and social functioning. Positive, negative, and disorganization symptoms mediated this relationship, although indirect effects were small. Higher-level EP tasks were more strongly associated with negative symptoms than lower-level tasks. Relationships between EP and both social functioning and positive symptoms were smaller in the first episode of psychosis than in established illness. CONCLUSIONS: The mediating relationship suggests that EP not only influences social dysfunction directly but contributes to negative and disorganization symptoms, which in turn impair social functioning. This pathway suggests that targeting negative and disorganization symptoms may ultimately improve social outcomes for individuals with psychosis. Future research, particularly in early psychosis, is needed to determine other factors impacting these interrelationships.
