Published: January 2024

Background: As climate change persists, accelerates, and intensifies, and since mitigating factors are absent, mental health impacts are expected to follow the same patterns. Therefore, it appears of utmost importance to deepen and broaden the knowledge and understanding of how and through which mechanisms climate change anxiety (CCA) may interplay with mental health outcomes. Based on the stress-vulnerability model of psychosis, the present study proposed to examine the relationship between CCA and psychotic experiences (PEs), and to test the theoretically-driven hypothesis that death anxiety acts as a mediator in this relationship. Method: This study adopted a cross-sectional approach involving a sample of young adults aged 18 to 35 years (mean age = 24.56 ± 22.49 years; 63.9% females) originating from, and residing in Lebanon. Results: The results of the mediation analysis showed that death anxiety partially mediated the association between CCA and PEs. Higher CCA was significantly associated with higher death anxiety; higher death anxiety was significantly associated with more PEs. Finally, higher CCA was directly and significantly associated with more PEs. Conclusion: Drawing from the present preliminary findings, the key tentative recommendation is that addressing death anxiety might alleviate the association between CCA and PEs. In addition, government decision-makers need to recognize the necessity of considering climate change implications on mental health in policy and decision-making.
Comparing stigma between French people experiencing schizophrenia versus bipolar disorders
Authors: Villani M. , Kovess–Masféty V. 
Published: January 2024

Background: Among the multiple challenges that people experiencing mental illness in general, and schizophrenia or bipolar disorders in particular, have to face, stigma appears to be one of the most difficult to tackle. In France, the body of research about stigma regarding people experiencing schizophrenia or bipolar disorders is growing, but not as much as in other western countries. Aims: In this context, our study aims to explore and compare stigma in French people experiencing schizophrenia or bipolar disorders, along with their respective mental healthcare system experience, in order to better address them within public health policies. Methods: 20 French mental health service users experiencing schizophrenia and 20 experiencing bipolar disorders answered the Stigma Scale, which assesses three dimensions of stigma (discrimination, difficulties of divulgation and lack of positive aspects). A semi-structured interview was used to collect information about the experience of the mental healthcare system (level of information, access to diagnosis, treatment, access to psychoeducation, etc.). Results: People experiencing schizophrenia and people experiencing bipolar disorders are different populations in terms of social impairment. However, they share a comparable negative experience of the mental healthcare system and a comparable level of information about their illness, to the exception of diagnosis divulgation, as people experiencing bipolar disorders have a better access to their diagnosis. People experiencing schizophrenia perceive a higher actual discrimination than people experiencing bipolar disorders. Conclusions: Public health policies should take into account the strong perception of actual discrimination of people experiencing schizophrenia, with capitalizing on what seems beneficial for people experiencing bipolar disorders.

Background: Pandemic fatigue generates low motivation or the ability to comply with protective behaviors to mitigate the spread of COVID-19. Aims: This study aimed to analyze the symptoms of pandemic fatigue through network analysis in individuals from five South American countries. Method: A total of 1,444 individuals from Argentina, Bolivia, Paraguay, Peru, and Uruguay participated and were evaluated using the Pandemic Fatigue Scale. The networks were estimated using the ggmModSelect estimation method and a polychoric correlation matrix was used. Stability assessment of the five networks was performed using the nonparametric resampling method based on the case bootstrap type. For the estimation of network centrality, a metric based on node strength was used, whereas network comparison was performed using a permutation-based approach. Results: The results showed that the relationships between pandemic fatigue symptoms were strongest in the demotivation dimension. Variability in the centrality of pandemic fatigue symptoms was observed among participating countries. Finally, symptom networks were invariant and almost identical across participating countries. Conclusions: This study is the first to provide information on how pandemic fatigue symptoms were related during the COVID-19 pandemic.

Background: Depression is a leading cause of disability and the conventional management has several limitations. Recent studies demonstrated the benefits of yoga in psychological disorders. Aims: To evaluate the efficacy of the Integrated Yoga Module (IYM) to standard care with added yogic education on lifestyle modification (YELM) in patients with clinical depression. Methods: A PROBE trial was conducted at a single tertiary care hospital in India. Adults aged 18 to 64 with clinical depression were randomized to either an IYM or an active control group using a computer-generated mixed block randomization sequence. Both groups received YELM in addition to standard care and the intervention group practiced IYM, for 8 weeks. The primary outcome was the reduction in depression symptoms assessed using the Beck Depression Inventory (BDI-II), and secondary outcomes involved self-compassion, brief resilience, positive and negative experiences, and quality of life, evaluated at 8 weeks. Results: The mean ± SD age of participants was 32.2 ± 10.0 and 54.3% were females. The IYM group showed statistically significant improvements in BDI-II scores β = −6.7 (95% CI [−10.8, −2.5]; p = .001), resilience β = 0.4 (95% CI [0.02, 0.80]; p = .037), physical health domain of WHOQOL - BREF β = 10.1 (95% CI [0.7, 19.5]; p = .035) and negative emotions (SPANE-N) β = 2.8 (95% CI [0.1, 5.4]; p = .037). However, no significant differences were found in SCS-SF β = −0.3 (95% CI [−0.7, 0.0]; p = .053). Conclusions: IYM as an adjunct is superior to conventional medical management in reducing symptoms and improving positive psychological resources in clinical depression.

Published: January 2024

Background: This study explores the lasting mental health impact of the Syria-Turkey earthquakes in 2023 on a population affected by conflict and trauma. It analyzes pre- and post-event mental health and sleep quality differences, identifying predictors of outcomes. Aims: Studying the 2023 Syria-Turkey earthquakes’ enduring mental health impact on conflict-affected individuals, this research informs better support and interventions for disaster survivors. Methods: This longitudinal, cross-sectional study examined the enduring mental health impact of the Syria-Turkey earthquakes. The present study involved N = 1,413 Syrian survivors, aged 18 years or older, who actively participated by contributing both pre- and post-earthquake data. A meticulously designed digital questionnaire with established metrics assessed sleep disturbances, depressive symptoms, and anxiety levels. Stratification variables (age, gender, education, marital status) were used for subgroup analysis. Arabic versions of PHQ-9, PSQI, and GAD-2 proved reliable for measuring depression, sleep quality, and anxiety. Results: The majority of participants were female (73.6%) with tertiary education (83.3%). Post-earthquake, a higher percentage reported poor sleep quality (67.7% vs. 59.7%, p < .001) and increased prevalence of MDE (66.1% vs. 56%, p < .001). GAD did not differ significantly. Post-earthquake, women had a higher likelihood of poor sleep quality (OR: 1.58, 95% CI [1.19, 2.10], p < .001) and MDE (OR: 1.55, 95% CI [1.18 to 2.04], p = .003). Predictors varied before and after earthquakes; age and education were significant predictors of poor sleep quality, MDE, and GAD. Conclusion: This study reveals higher rates of poor sleep quality and major depressive episodes among earthquake-affected individuals, especially women. Age, education, and gender contribute to these outcomes. Targeted interventions and comprehensive mental health support are crucial for post-earthquake recovery.

Published: January 2024

Background: Mental health literacy (MHL) has been related to health behaviors and outcomes. However, studies examining MHL as a barrier and facilitator to service use are limited, especially among minority groups. Aims: This study examined MHL as a barrier and facilitator to mental health service use among the Palestinian Bedouin minority in Israel. Methods: Twenty-five Bedouins (15 women) from southern Israel participated in semi-structured, in-depth interviews. The participants were recruited by publishing an ad on social media about the study, then through a snowball technique. The data were analyzed thematically using ATLAS.ti.9, and the intercoder reliability was 92%. Results: We identified four major themes in the interviews: (1) MHL as a barrier to service use, due to lack of knowledge about professionals in the field, mental health services, or reasons and risk factors for mental health problems; (2) traditional attitudes that acted as barriers to service use, including a preference for informal treatment, a lack of faith in mental health treatment, aversion to discussing private feelings, and the perception that mental health is a luxury; (3) MHL as a facilitator to service use by enabling accurate identification of mental distress and suggesting practical avenues for seeking help; and (4) ways to improve MHL that should be culturally sensitive and under the government agencies’ responsibility. Conclusions: Interventions aimed at increasing the use of mental health services among Bedouins and reducing racial/ethnic disparities should increase knowledge in culturally adapted ways, especially regarding professionals and services, and change negative attitudes such as mental health treatment as ineffective or bonus.
The Bright Side of Risk-Taking: Evidence From Financial Analysts
Authors: Jiang Jinglin , Liu Bo 
Published: January 2024

This study investigates the relationship between analysts’ facial width-to-height ratio (fWHR) and their selected forecast boldness under different conditions (e.g., tournament condition and skill levels). The aim is to determine if fWHR captures innate or calculated risk-taking preferences. Supplementary tests reveal that high-fWHR analysts issuing bold forecasts achieve more favorable outcomes in terms of job promotion and forecast accuracy compared with their low-fWHR peers, providing supporting evidence that fWHR is associated with calculated risk-taking. In addition, tests conducted on stock price non-synchronicity and market reaction to bold forecasts for high- versus low-fWHR analysts suggest that high-fWHR analysts possess more firm-specific private information.

Amphetamine use disorder is associated with striatum hypoactivation during anticipation of loss and reward
Authors: May April C , Burrows Kaiping , Kuplicki Rayus , Paulus Martin P , Stewart Jennifer L 
Published: January 2024

Background: Dysregulated ventral striatum function has been proposed as one important process occurring in individuals with substance use disorder. This study investigates the role of altered reward and loss anticipation, which is an important component of impaired decision-making, impulsivity, and vulnerability to relapse in individuals with amphetamine use disorder (AMP). Aims: To determine whether AMP is associated with blunted striatum, prefrontal cortex, and insula signals during win and loss anticipation. Methods: Participants with and without AMP (AMP+ n = 46, AMP− n = 90) from the Tulsa 1000 study completed a monetary incentive delay (MID) task during functional magnetic resonance imaging. Results: Group main effects indicated that: (1) AMP+ exhibited lower bilateral caudate/putamen and left nucleus accumbens signal than AMP− across anticipation of wins and losses; and (2) AMP+ showed slower reaction times than AMP− during loss anticipation. Group*condition interactions demonstrated that AMP+ exhibited greater right amygdala signal than AMP− while anticipating large wins, a pattern that reversed when anticipating small losses. Left caudate/putamen attenuations in AMP+ during small loss anticipation were also evident. Groups did not differ in prefrontal or insula signals. Conclusions: AMP+ individuals have altered neural processing and response patterns during reward and loss anticipation, potentially reflecting impairments in dopamine function, which may influence their decision-making and reactions to different win/loss scenarios. These findings help to explain why AMP+ have difficulty with decision-making and exhibit a heightened focus on immediate rewards or punishments.
MDMA enhances positive affective responses to social feedback
Authors: Bershad Anya K , Hsu David T , de Wit Harriet 
Published: January 2024

Background: The prosocial compound ± 3,4-methylenedioxymethamphetamine (MDMA) is an amphetamine derivative that has shown promise as an adjunct to psychotherapy in the treatment of post-traumatic stress disorder. MDMA increases positive responses to social images, and it has been suggested that the ability of MDMA to positively bias social perception may underlie its therapeutic efficacy as a psychotherapy adjunct. However, the effect of the compound on affective responses to positive or negative social feedback has not been tested. Aims: In this study, we aimed to test the effects of MDMA compared to placebo and the prototypical stimulant, methamphetamine (MA), on responses to positive and negative social feedback. Methods: This was a double-blind, placebo-controlled, crossover trial (NCT03790618), comparing the effects of two doses of MDMA (0.75 mg/kg, 1.5 mg/kg) to both placebo and MA (20 mg) on responses to a personalized social feedback task, similar to a dating app, in healthy adult volunteers ages 18–40 ( N = 36, 18 women, 18 men). Results/Outcomes: The high dose of MDMA increased positive affective responses to social feedback. Conclusions/Interpretations: These findings suggest one process by which MDMA may facilitate social connection. Further work is needed to understand how MDMA affects responses to more generalized types of social feedback and to understand these effects in clinical populations.

Published: January 2024

Background: Clozapine is the primary antipsychotic (APD) for treatment-resistant schizophrenia (TRS). However, only 40% of patients with TRS respond to clozapine, constituting a subgroup of clozapine-resistant patients. Recently, the neuropeptide orexin-A was shown to be involved in the pathophysiology of schizophrenia. This study evaluated the association of orexin-A levels with the clozapine response in patients with TRS. Methods: We recruited 199 patients with schizophrenia, including 37 APD-free and 162 clozapine-treated patients. Clozapine-treated patients were divided into clozapine-responsive ( n = 100) and clozapine-resistant ( n = 62) groups based on whether they had achieved psychotic remission defined by the 18-item Brief Psychiatric Rating Scale (BPRS-18). We compared blood orexin-A levels among the three groups and performed regression analysis to determine the association of orexin-A level with treatment response in clozapine-treated patients. We also explored the correlation between orexin-A levels and cognitive function, assessed using the CogState Schizophrenia Battery. Results: Clozapine-responsive patients had higher orexin-A levels than clozapine-resistant and APD-free patients. Orexin-A level was the only factor significantly associated with treatment response after adjustment. Orexin-A levels were negatively correlated with BPRS-18 full scale and positive, negative, and general symptoms subscale scores. We also observed a positive correlation between orexin-A levels and verbal memory, visual learning and memory, and working memory function. Conclusions: This cross-sectional study showed that higher levels of orexin-A are associated with treatment response to clozapine in patients with TRS. Future prospective studies examining changes in orexin-A level following clozapine treatment and the potential benefit of augmenting orexin-A signaling are warranted.

In recent years, advancements in Light Detection and Ranging (LiDAR) technology have made 3D LiDAR sensors more compact, lightweight, and affordable. This progress has spurred interest in integrating LiDAR with sensors such as Inertial Measurement Units (IMUs) and cameras for Simultaneous Localization and Mapping (SLAM) research. Public datasets covering different scenarios, platforms, and viewpoints are crucial for multi-sensor fusion SLAM studies, yet most focus on handheld or vehicle-mounted devices with front or 360-degree views. Data from aerial vehicles with downward-looking views is scarce, existing relevant datasets usually feature low altitudes and are mostly limited to small campus environments. To fill this gap, we introduce the Multi-sensor Aerial Robots SLAM dataset (MARS-LVIG dataset), providing unique aerial downward-looking LiDAR-Visual-Inertial-GNSS data with viewpoints from altitudes between 80 m and 130 m. The dataset not only offers new aspects to test and evaluate existing SLAM algorithms, but also brings new challenges which can facilitate researches and developments of more advanced SLAM algorithms. The MARS-LVIG dataset contains 21 sequences, acquired across diversified large-area environments including an aero-model airfield, an island, a rural town, and a valley. Within these sequences, the UAV has speeds varying from 3 m/s to 12 m/s, a scanning area reaching up to 577,000 m2, and the max path length of 7.148 km in a single flight. This dataset encapsulates data collected by a lightweight, hardware-synchronized sensor package that includes a solid-state 3D LiDAR, a global-shutter RGB camera, IMUs, and a raw message receiver of the Global Navigation Satellite System (GNSS). For algorithm evaluation, this dataset releases ground truth of both localization and mapping, which are acquired by on-board Real-time Kinematic (RTK) and DJI L1 (post-processed by its supporting software DJI Terra), respectively.

Published: January 2024

Background: Current classification systems for intra-articular pathology intraoperatively have been described for patients with femoroacetabular impingement rather than dysplasia. Purpose: To (1) describe intra-articular findings in dysplastic hips undergoing combined hip arthroscopy and periacetabular osteotomy (PAO); (2) propose a new chondrolabral classification system for dysplastic hips based on these findings; and (3) correlate patient-reported outcome measures (PROM) with the newly proposed classification. Study Design: Case series; Level of evidence, 4. Methods: A total of 46 hips underwent combined hip arthroscopy and PAO at our institution between September 2013 and December 2014, irrespective of symptoms or radiographic findings. PROMs were evaluated preoperatively and at 2 years postoperatively. At the time of hip arthroscopy, the chondrolabral junction was classified as normal without tear (1 hip, type 1); hypertrophic labrum without chondrolabral disruption (19 hips, type 2); chondrolabral disruption on the articular side, not extending into the capsular side (16 hips, type 3A); chondrolabral disruption extending through the capsular side (3 hips, type 3B); and exposed acetabular subchondral bone (7 hips, type 4). Results: There was a significant difference in postoperative modified Harris Hip Score (mHHS) ( P = .020), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores ( P = .037), and WOMAC total scores ( P = .049) between chondrolabral junction types. Post hoc analyses demonstrated significant differences between type 2 (84.9 ± 12.9) and type 3A (67.8 ± 20.7; P = .198), and between type 2 and type 4 (59.3 ± 24.3; P = .011) in postoperative mHHS scores; and between type 2 (83.9 ± 12.9) and type 3A (68.9 ± 23.7; P = .045) in postoperative WOMAC total scores. In multivariate analysis, chondrolabral type 3 or type 4, age >35 years, and previous surgery were significantly correlated with worse mHHS scores at 2 years. Conclusion: This new chondrolabral classification is proposed to describe intra-articular pathology seen during combined hip arthroscopy and PAO, specifically in dysplastic hips. More advanced chondrolabral disease was associated with worse PROMs at 2 years.
