Authors: Zhang Jingyun , Shi Jiayuan , Zeng Kehao , Cai Mengjie , Lan Xingguo
Published: January 2024

Betula platyphylla, belonging to the cold-specialized lineage Betulaceae, exhibits a unique reproductive strategy where staminate catkins emerge in the first summer and undergo an overwintering process, culminating in flowering in the following year. However, the underlying regulatory mechanism remains unclear. In this study, we investigated the male germline development ofB. platyphyllain four distinct stages: microsporocytes in Oct. (S1), uninuclear microspores from Dec. (S2) to Mar. of the following year (S3), and bicellular microspores in Apr. (S4). We performed RNA sequencing on mature pollen and the four stages of staminate catkins. Using weighted gene co-expression network analysis (WGCNA), we identified five highly correlated gene modules with distinct expression profiles. These modules exhibited strong correlations with sugar metabolism, cell cycle, flowering, and cell wall dynamics, highlighting their dynamic roles during male germline developmental stages. During the overwintering process, we observed that the expression of transcription factors such asBpDUO1andBpAMSat the appropriate developmental stages, suggests their significant roles in male germline development. The expression patterns ofBpFLCandBpFTsuggest their potential involvement in temperature perception during male reproductive development. These findings offer valuable insights into the reproductive success of plants adapting to cold environments.
Virus induced gene silencing confirms oligogenic inheritance of brown stem rot resistance in soybean

Published: January 2024

Brown Stem Rot (BSR), caused by the soil borne fungal pathogen Phialophora gregata, can reduce soybean yields by as much as 38%. Previous allelism studies identified three Resistant to brown stem Rot genes (Rbs1, Rbs2, and Rbs3), all mapping to large, overlapping regions on soybean chromosome 16. However, recent fine-mapping and genome wide association studies (GWAS) suggest Rbs1, Rbs2, and Rbs3 are alleles of a single Rbs locus. To address this conflict, we characterized the Rbs locus using the Williams82 reference genome (Wm82.a4.v1). We identified 120 Receptor-Like Proteins (RLPs), with hallmarks of disease resistance receptor-like proteins (RLPs), which formed five distinct clusters. We developed virus induced gene silencing (VIGS) constructs to target each of the clusters, hypothesizing that silencing the correct RLP cluster would result in a loss of resistance phenotype. The VIGS constructs were tested against P. gregata resistant genotypes L78-4094 (Rbs1), PI 437833 (Rbs2), or PI 437970 (Rbs3), infected with P. gregata or mock infected. No loss of resistance phenotype was observed. We then developed VIGS constructs targeting two RLP clusters with a single construct. Construct B1a/B2 silenced P. gregata resistance in L78-4094, confirming at least two genes confer Rbs1-mediated resistance to P. gregata. Failure of B1a/B2 to silence resistance in PI 437833 and PI 437970 suggests additional genes confer BSR resistance in these lines. To identify differentially expressed genes (DEGs) responding to silencing, we conducted RNA-seq of leaf, stem and root samples from B1a/B2 and empty vector control plants infected with P. gregata or mock infected. B1a/B2 silencing induced DEGs associated with cell wall biogenesis, lipid oxidation, the unfolded protein response and iron homeostasis and repressed numerous DEGs involved in defense and defense signaling. These findings will improve integration of Rbs resistance into elite germplasm and provide novel insights into fungal disease resistance.

Published: January 2024

Phoebe bournei is one of the main afforestation tree species in subtropical regions of China and is famous for its timber. Its distribution and growth are significantly impaired by water conditions. Thus, it is essential to understand the mechanism of the stress response in P. bournei. Here, we analyzed the phenotypic changes and transcriptomic rearrangement in the leaves and roots of P. bournei seedlings grown for 0 h, 1 h, 24 h, and 72 h under simulated drought conditions (10% PEG 6000). The results showed that drought stress inhibited plant photosynthesis and increased oxidoreductase activity and abscisic acid (ABA) accumulation. Spatio-temporal transcriptomic analysis identified 2836 and 3704 differentially expressed genes (DEGs) in leaves and roots, respectively. The responsive genes in different organs presented various expression profiles at different times. Gene co-expression network analysis identified two core transcription factors, TGA4 and APRR2, from two modules that showed a strong positive correlation with ABA accumulation. Our study investigated the different responses of aboveground and belowground organs of P. bournei to drought stress and provides critical information for improving the drought resistance of this timber species.

Forests are critical in the terrestrial carbon cycle, and the knowledge of their response to ongoing climate change will be crucial for determining future carbon fluxes and climate trajectories. In areas with contrasting seasons, trees form discrete annual rings that can be assigned to calendar years, allowing to extract valuable information about how trees respond to the environment. The anatomical structure of wood provides highly-resolved information about the reaction and adaptation of trees to climate. Quantitative wood anatomy helps to retrieve this information by measuring wood at the cellular level using high-resolution images of wood micro-sections. However, whereas large advances have been made in identifying cellular structures, obtaining meaningful cellular information is still hampered by the correct annual tree ring delimitation on the images. This is a time-consuming task that requires experienced operators to manually delimit ring boundaries. Classic methods of automatic segmentation based on pixel values are being replaced by new approaches using neural networks which are capable of distinguishing structures, even when demarcations require a high level of expertise. Although neural networks have been used for tree ring segmentation on macroscopic images of wood, the complexity of cell patterns in stained microsections of broadleaved species requires adaptive models to accurately accomplish this task. We present an automatic tree ring boundary delineation using neural networks on stained cross-sectional microsection images from beech cores. We trained a UNETR, a combined neural network of UNET and the attention mechanisms of Visual Transformers, to automatically segment annual ring boundaries. Its accuracy was evaluated considering discrepancies with manual segmentation and the consequences of disparity for the goals of quantitative wood anatomy analyses. In most cases (91.8%), automatic segmentation matched or improved manual segmentation, and the rate of vessels assignment to annual rings was similar between the two categories, even when manual segmentation was considered better. The application of convolutional neural networks-based models outperforms human operator segmentations when confronting ring boundary delimitation using specific parameters for quantitative wood anatomy analysis. Current advances on segmentation models may reduce the cost of massive and accurate data collection for quantitative wood anatomy.
The role of anticipated emotions in self-control: linking self-control and the anticipatory ability to engage emotions associated with upcoming events

Published: January 2024

Self-control is typically attributed to “cold” cognitive control mechanisms that top-down influence “hot” affective impulses or emotions. In this study we tested an alternative view, assuming that self-control also rests on the ability to anticipate emotions directed toward future consequences. Using a behavioral within-subject design including an emotion regulation task measuring the ability to voluntarily engage anticipated emotions towards an upcoming event and a self-control task in which subjects were confronted with a variety of everyday conflict situations, we examined the relationship between self-control and anticipated emotions. We found that those individuals (n = 33 healthy individuals from the general population) who were better able to engage anticipated emotions to an upcoming event showed stronger levels of self-control in situations where it was necessary to resist short-term temptations or to endure short-term aversions to achieve long-term goals. This finding suggests that anticipated emotions may play a functional role in self-control-relevant deliberations with respect to possible future consequences and are not only inhibited top-down as implied by “dual system” views on self-control.
Unveiling the links between physical activity, self-identity, social anxiety, and emotional eating among overweight and obese young adults
Authors: Wang Huilin , He Xianyi , Tang Yiwei , Tang Jiaxin , Yang Jingyu
Published: January 2024

Introduction

Emotional eating not only contributes to physical obesity but also leads to the experience of guilt and shame, exacerbating emotional problems. Increasing physical activity, adopting a balanced diet, and seeking psychological support help improve emotional eating issues in overweight or obese young adults, enhancing overall mental and physical well-being.

Methods

This study investigates the correlation between physical activity, self-identity, social anxiety, and emotional eating among 373 overweight and obese college students aged 18–26 in central China. By utilizing AMOS v.26, a structural equation model was constructed to examine the hypotheses.

Results

The findings reveal that physical activity significantly influences self-identity and social anxiety, which, in turn, significantly impact emotional eating. Moreover, self-identity and social anxiety serve as mediators in the relationship between physical activity and emotional eating. These results emphasize the role of physical activity in mitigating emotional eating among young individuals struggling with overweight and obesity.

Discussion

Consequently, the government and relevant agencies are urged to address the issue of obesity among young adults and provide support for their engagement in physical activity.
Does environmental management system certification affect green innovation performance?—Based on a moderated mediating effects model
Authors: Zhang Jinsong , Wang Mengmeng , Li Muyao
Published: January 2024

What is the impact of environmental management system certification on green innovation performance, and is it a futile endeavor or a profitable one? Grounded in the principles of ecological civilization construction and green development, this study embarks on a comprehensive examination. Initially, it investigates the varying impacts of environmental management system certification on both traditional innovation performance and green innovation performance. Subsequently, it dissects the underlying mechanisms and moderating factors influencing the latter, including an exploration of intermediary effects. The empirical findings of this study are as follows: (i) Environmental management system certification emerges as a catalyst for innovation performance, with the primary impact observed in the realm of green innovation performance. (ii) Social responsibility disclosure is identified as a mediating factor in the relationship between environmental management system certification and green innovation performance. (iii) Larger enterprises, those equipped with robust equity incentives, and those operating in less competitive markets are more prone to benefit from the impact of environmental management system certification on social responsibility disclosure. This, in turn, amplifies the promotion of green innovation performance. However, the moderating effect of property rights on the mediating path remains statistically insignificant. (iv) Environmental management system certification exerts a more pronounced influence on green innovation performance in regions characterized by lower economic development. Moreover, it particularly stimulates exploratory green innovation performance, surpassing its impact on exploitative green innovation performance.
Psychological correlates of body dissatisfaction in Swiss youth over a one-year study-period
Authors: Mueller Verena M. , Forrer Felicitas , Meyer Andrea H. , Munsch Simone
Published: January 2024

Introduction

It is well known that young individuals often report pronounced negative perceptions and attitudes towards their own body or intense fear of being not muscular enough. There is much less data available, however, on the role of psychological mechanisms on these perceptions and attitudes, such as emotion regulation difficulties, correlates of alexithymia, and appearance-related rejection sensitivity.

Methods

We therefore set out to assess associations between these psychological mechanisms, and body image as well as muscle dysmorphic symptoms. Our sample was recruited as part of a larger-scale study aiming at assessing correlates of mental health (with a focus on eating disorder symptoms) in German speaking Switzerland. The first wave (T1), starting in April 2021, included 605 participants (80% female, 19.6 ± 2.5 years) who completed the online-questionnaire and were reassessed in a second wave (T2), one year later.

Results

Results indicated that at both waves, emotion regulation difficulties [DERS-SF] and appearance-based rejection sensitivity [ARS-D] were both positively cross-sectionally associated with body dissatisfaction [BSQ-8C] and muscle dysmorphic symptoms [MDDI] at the first assessment time-point and one year later at follow-up assessment. Moreover, alexithymia [TAS-20] was positively cross-sectionally associated with muscle dysmorphic symptoms at both waves. We further observed high absolute and relative level stabilities for all variables involved across the one-year study period.

Discussion/Conclusion

Even though the effects for some associations were rather small, our findings underline the relevance of such mechanisms in the development of body dissatisfaction and to a lesser extent of muscle dysmorphia symptoms over the period of one year. Additional research is necessary to replicate these findings in other youth samples.

Published: January 2024

This study aims to investigate the wellbeing of Iranian English as Foreign Language (EFL) teachers across their career stages in terms of teaching experience. In this regard, the study categorized teachers into three groups based on their experience: novice, experienced, and highly experienced. Using a quantitative and cross-sectional survey design, this study employed a validated scale to measure psychological wellbeing, positive perception about self and life, goal setting and time management, and positive relationships among teachers. Using a convenience sampling procedure, 182 teachers participated in the study, representing varying age ranges, teaching experience, and employment status. The data was collected through an online survey within a month and underwent descriptive and inferential statistical analyses using SPSS software. The results revealed significant differences in the wellbeing of language teachers across experience groups. More specifically, novice teachers scored lower in various wellbeing dimensions than experienced and highly experienced teachers. These findings emphasize the importance of considering career stages when investigating teachers’ professional wellbeing. The findings also contribute to a deeper understanding of the relationship between teaching experience and wellbeing, with implications for supporting the EFL teachers’ wellbeing and informing educational policies and practices. The study results are discussed, and the related implications are provided for running professional development courses to enhance teachers’ wellbeing.
Integrating mental health into climate change education to inspire climate action while safeguarding mental health
Authors: Newberry Le Vay Jessica , Cunningham Alex , Soul Laura , Dave Heena , Hoath Leigh , Lawrance Emma L.
Published: January 2024

Climate change is the greatest threat humanity faces, and puts at risk the mental health and wellbeing of children and young people. Climate change education must equip children and young people with the knowledge, skills and resilience to live in an uncertain future, sustainably take relevant climate action and work in climate careers. As attention on climate change education grows, this is a critical moment for the mental health community to ensure mental health and wellbeing considerations are embedded. Critically, appropriate integration of mental health can enable these very necessary goals of equipping children and young people to live and work in a future where climate change looms large. This paper explores why promoting good mental health and wellbeing and building psychological resilience can help achieve climate change education outcomes, and why not doing so risks harming children and young people’s mental health. It also explores how integrating discussions about emotions, mental health, and coping strategies within climate change education can be a route into wider discussions about mental health, to support children and young people in the context of rising mental health needs. Learning from an existing approach to promoting good mental health and wellbeing in schools (the ‘whole school approach’) provides the opportunity to explore one avenue through which such an integrated approach could be implemented in practice. Identifying appropriate mechanisms to integrate mental health into climate change education will require co-design and research with educators and young people, and addressing systemic barriers facing the schools sector.
The influence of tai chi on the death anxiety of elderly people living alone: the chain mediating effect of social support and psychological capital
Authors: Zhou Jiali , Wu Baoyuan , Su Lining , Ma Xiujie
Published: January 2024

Background

Population aging is a global trend, and the number of older adults living alone is increasing. Tai chi, a traditional Chinese exercise, has been shown to improve the physical and mental health of older adults.

Aim

To investigate the effects of tai chi on death anxiety in older adults living alone and the role of social support and psychological capital in this relationship.

Method

A cross-sectional study of 493 older adults living alone in four cities in southwestern China. Participants were assessed using questionnaires on tai chi practice, social support, psychological capital, and death anxiety.

Results

Tai chi practice significantly reduced death anxiety in older adults living alone. It also positively correlated with social support and psychological capital, both of which negatively correlated with death anxiety. Social support and psychological capital mediated the relationship between tai chi practice and death anxiety, suggesting that tai chi may reduce death anxiety through these factors. These findings encourage older adults living alone to practice tai chi, as it may improve their mental and physical health and reduce their risk of death anxiety.

Conclusion

Tai chi practice may reduce death anxiety in older adults living alone through the chain-mediated effects of social support and psychological capital. This suggests that tai chi may be a beneficial intervention for older adults living alone.

Published: January 2024

In recent years, the widespread use of the Internet has led to increasing concerns about problematic behaviors related to excessive Internet use and their potential consequences. This study aimed to investigate the relationship between Internet addiction (IA), body mass index (BMI), and emotion dysregulation (ED). Specifically, the study aimed to determine if IA significantly predicts obesity and if both Internet addiction and obesity can be significantly predicted by ED. 367 school-attending adolescents (Mage = 13.35; SD = 0.82; 49% girls) in Tekab participated in the study. Participants completed the Difficulties in Emotion Regulation Scale (DERS) and the Internet Addiction Test (IAT), while BMI was calculated using self-reported data to assess their obesity levels. The results indicated that ED significantly predicted both IA and increased BMI levels (p < 0.001). Furthermore, IA also significantly predicted elevated BMI levels (p < 0.001). Our findings showed that ED significantly predicted both higher IA and BMI values, while IA also significantly predicted elevated BMI levels These results have important implications for treatment. To address excessive Internet use or overeating behavior in individuals with either condition, it may be necessary to target the underlying emotional dysregulation that contributes to the problem.
Sustainable materials: a linking bridge between material perception, affordance, and aesthetics
Authors: Strappini Francesca , Fagioli Sabrina , Mastandrea Stefano , Scorolli Claudia
Published: January 2024

The perception of material properties, which refers to the way in which individuals perceive and interpret materials through their sensory experiences, plays a crucial role in our interaction with the environment. Affordance, on the other hand, refers to the potential actions and uses that materials offer to users. In turn, the perception of the affordances is modulated by the aesthetic appreciation that individuals experience when interacting with the environment. Although material perception, affordances, and aesthetic appreciation are recognized as essential to fostering sustainability in society, only a few studies have investigated this subject matter systematically and their reciprocal influences. This scarcity is partially due to the challenges offered by the complexity of combining interdisciplinary topics that explore interactions between various disciplines, such as psychophysics, neurophysiology, affective science, aesthetics, and social and environmental sciences. Outlining the main findings across disciplines, this review highlights the pivotal role of material perception in shaping sustainable behaviors. It establishes connections between material perception, affordance, aesthetics, and sustainability, emphasizing the need for interdisciplinary research and integrated approaches in environmental psychology. This integration is essential as it can provide insight into how to foster sustainable and durable changes.
The impact of employees’ experience of high-performance work systems on innovative behavior in professional service firms
Authors: Arshad Beenish , Hassan Hamid , Azam Akbar
Published: January 2024

This research examines the impact of employees’ experience of high-performance work systems (HPWS) on their innovative behavior. The study draws upon social exchange theory to propose that employees’ experience of HPWS influences their innovative behavior directly and through sequential mediation of social capital development and knowledge-sharing behavior. Additionally, the study uses the Elaboration Likelihood Model to highlight that individuals’ need for cognition strengthens the relationship between employees’ knowledge-sharing and innovative behaviors. The study employed a time-lagged quantitative research design with survey data from 262 job incumbents in professional service firms. The proposed model was tested using the PLS-SEM two-stage approach. The findings of the study confirm the proposed direct and indirect relationships. Moreover, the findings also confirm that the need for cognition strengthens the relationship between knowledge-sharing and individual innovation behaviors. The study posits that employees’ experience of HRM systems can influence their innovative behavior as a reciprocal exchange toward the employer. Moreover, this study presents a comprehensive model that highlights the interplay of social and cognitive factors that can influence the relationship between HPWS and employees’ innovation behavior. This study also fills a gap in the existing literature by highlighting the antecedents of innovative behavior in professional service firms.
Turning ingroup wounds into bonds: perceptions of gender inequalities predict attitudes toward other minorities
Authors: Ciaffoni Stefano , Rubini Monica , Moscatelli Silvia
Published: January 2024

Despite significant strides in reducing gender disparities over the past decades, women still face disparities in several domains. While extensive research has explored the various consequences of gender inequalities for women, this study (N = 493 participants) delves into a less-explored dimension, investigating whether and how perceiving gender inequalities is associated with attitudes toward minorities. Drawing on relative deprivation theory and intra-minority solidarity research, we examined the relationship between women's perceptions of gender inequalities—spanning workplace inequality, domestic inequality, sexual harassment, and social expectations—and attitudes toward gays and lesbians, transgender women, and immigrants. We also explored whether indignation, arising from recognizing unjust circumstances, mediated these relationships, and the moderating role of perceived friends' support for gender equality. The results of the path analyses unveiled a nuanced relationship. While women who were more aware of gender inequalities exhibited more positive attitudes toward gays and lesbians and transgender women, no such relationship was observed regarding immigrants. Indignation and perceived friends' support for gender equality were key factors in fostering positive intergroup attitudes. Regarding their moderating role, perceived social norms only influenced the relationship between indignation and attitudes toward gays and lesbians. These findings shed light on the intricate interplay between gender inequalities and minority group attitudes. Recognizing the multifaceted nature of gender inequality and its emotional impact can catalyze promoting coalitional attitudes and collective action among disadvantaged groups. The study also underscores the potential of close groups' norms in promoting positive intergroup attitudes, warranting further exploration.
Evaluation of the psychometric properties of the Italian version of the 10-item perceived stress scale in a sample of teachers
Authors: Messineo Linda , Tosto Crispino
Published: January 2024

Background

The 10-item Perceived Stress Scale is a widely used questionnaire for measuring perceived stress.

Aim

This study aimed to assess the psychometric properties of the Italian version of the 10-item Perceived Stress Scale in a sample of Italian teachers during the COVID-19 pandemic.

Methods

A cross-sectional study was performed. A sample of 1,179 teachers of pre-primary, primary, and secondary schools anonymously completed an online questionnaire. A Confirmatory Factor Analysis was performed to compare the fit of a two-factor model against a one-factor solution of the scale. Multigroup CFA was run to test the measurement invariance of the two-factor PSS-10 solution across gender. The internal reliability of the scale was evaluated using Cronbach’s alpha and McDonald’ omega coefficients. Convergent validity with measures of subjective well-being and self-reported health was evaluated.

Results

The results of the Confirmatory Factor Analysis showed that the two-factor structure of the 10-items Perceived Stress Scale provided a better fit to the data and supported the adequacy of the Italian version of the scale. The two-factor model showed measurement invariance across female and male groups, as result of the multigroup CFA. The scale proved to have good internal reliability. Correlation analyses with measures of the Positive Affect and Negative Affect Schedule and self-reported health supported convergent validity.

Conclusion

These results suggest that the Italian version of the 10-item Perceived Stress Scale has good psychometric properties and can be considered a valid and reliable instrument to assess perceived stress.

Authors: Yang Yujie , Wang Chang
Published: January 2024

Background

The implementation of humanistic care is conducive to providing high quality nursing, improving patient satisfaction and establishing harmonious nursery-patient relationship. Current researchs show that humanistic caring ability is affected by emotional intelligence, empathy, interpersonal communication. But the exact relationship and internal mechanism of such factors have not been fully understood.

Objective

To explore the multiple mediating effect of empathy and communication ability on nursing students’ emotional intelligence and caring ability.

Methods

A case study was conducted by examining a sample of 1,165 nursing students from a junior college in Anhui, China. The multidimensional scales, and a self-designed demographic characteristics questionnaire were utilized. Path relationships and mutual effects were tested using structural equation modeling (SEM).

Results

Emotional intelligence, empathy, and communication ability were found to positively affect nursing students’ caring ability, as well as positive interrelationships with one another (standardized estimate = 0.312–0.584, p < 0.001). Communication ability and empathy play an important role in mediating the association between emotional intelligence and caring ability, and the effect sizes are 0.169 and 0.121, respectively, while the effect value of empathy and communication ability in emotional intelligence and caring ability was 0.034, which showed partial mediation of the association. The indirect effect of the structural equation was 77.14%.

Conclusion

The chain mediating role of empathy and communication ability in emotional intelligence and caring ability is explored, which not only enrichis previous studies, but also reveals the mechanism of emotional intelligence’s influence on caring ability. It is essential to continuously improve nursing students’ caring ability. From the perspective of nursing educators, they need to develop targeted approaches to help the nursing student improve their emotional intelligence, empathy, and communication skills, further enhancing their caring ability.

Increased metabolic variability in Korean patients with new onset bipolar disorder: a nationwide cohort study
Authors: Baek Ji Hyun , Han Kyungdo , Kim Hyewon , Yang Kyojin , Jeon Hong Jin
Published: January 2024

Introduction

The aim of this study was to determine associations between changes of metabolic parameters and the development of BD using nationally representative data.

Methods

We used health examination data provided by the South Korean National Health Insurance System (NHIS) (n = 8,326,953). The variability of each metabolic parameter including weight circumference, blood pressure, fasting blood glucose, high-density lipoprotein cholesterol, and triglyceride levels was caculated using variability independent of mean (VIM) indices. The presence of metabolic syndrome was associated with new onset BD. Each metabolic parameter with high variability was associated with a higher risk of new onset BD compared to those with low variability after adjusting for age, sex, smoking, alcohol drinking, regular exercise, income status, baseline diabetes, hypertension, and dyslipidemia.

Results

As the number of highly variable metabolic parameters increased, the risk for new onset depression also increased even after covariates adjustment. The associations between new onset BD and metabolic variability were greater in populations with age > 50 years. In addition, these associations remained significant after adjusting for the presence of depression prior to diagnoses of BD.

Discussion

Our results suggest possibility of metabolic variability as an independent environmental risk factor for BD even after adjusting for the presence of metabolic syndrome.
Compassion focused therapy for self-stigma and shame in autism: a single case pre-experimental study
Authors: Riebel Marie , Krasny-Pacini Agata , Manolov Rumen , Rohmer Odile , Weiner Luisa
Published: January 2024

Introduction

Exposure to public stigma can lead to the internalization of autism-related stigma (i.e., self-stigma), associated with negative health, occupational and social outcomes. Importantly, self-stigma is linked to shame and social isolation. Although elevated self-stigma has been reported in autistic adults, to the best of our knowledge, interventions designed to target this issue are lacking. Compassion is an effective way to reduce the emotional correlates of self-stigma (i.e., shame) and their impacts on mental health. However, no study has investigated whether compassion focused therapy (CFT) can effectively reduce self-stigma in autistic adults. The present study aims at investigating whether and how self-compassion improvement following CFT may reduce self-stigma and shame in an autistic individual.

Methods

A single case pre-experimental design (SCED) was used with weekly repeated measures during four phases: (i) pure baseline without any intervention (A), (ii) case conceptualization (A’), (iii) intervention (B) where CFT was delivered, (iv) follow-up without intervention (FU). The participant is a 46-year-old autistic man with high self-stigma and shame. Self-report measures of self-compassion and self-stigma and a daily idiographic measure of shame were used.

Results

There was a large increase in self-compassion between pure baseline (A) and the intervention phase (A’B) (Tau-U = 0.99), maintained at follow-up. Similarly, there was a moderate decrease of self-stigma (Tau-U = 0.32). In contrast, when we compared the whole baseline phase AA’ (i.e., considering the conceptualisation phase as baseline) to the intervention (B), there was no change in self-stigma (Tau-U = −0.09). There was no change in self-stigma between the intervention (B) and follow-up (Tau-U = −0.19). There was a moderate decrease in daily shame reports between the baseline (AA’) and the intervention (B) (Tau-U = 0.31) and a moderate decrease between the pure baseline (A) and intervention phase (A’B) (Tau-U = 0.51).

Conclusion

CFT was feasible for this autistic client and our results show that CFT led to the improvement of self-compassion. Changes on self-stigma measures were moderate. Self-stigma may need more time to change. Because self-stigma is involved in poorer social functioning and mental health in autistic adults, our results are promising and suggesting conducting more large-scale studies on CFT in autistic adults.
The impact of problematic mobile phone use and the number of close friends on depression and anxiety symptoms among college students
Authors: Wang Wei , Xu Huiqiong , Li Shuqin , Jiang Zhicheng , Sun Yanjun , Wan Yuhui
Published: January 2024

Background

Psychological problems often occur in college students, with the most common ones being depression and anxiety symptoms. Exploring the risk factors that influence depression and anxiety symptoms in college students is essential to promote their physical and mental health.

Objective

This study aimed to investigate the independent and interaction effects of problematic mobile phone use (PMPU) and the number of close friends (NCFs) on depression and anxiety symptoms and the comorbidity of these symptoms among college students.

Methods

A cross-sectional survey was conducted in Huainan, Anhui Province, and Suzhou, Jiangsu Province in China from October to December 2022. Data from 7,617 college students were collected. The Patient Health Questionnaire and Generalized Anxiety Disorder-7 were used to evaluate depression and anxiety symptoms. The PMPU data were collected by the Mobile Phone Addiction Type Scale. Multinomial logistic regression models were performed to examine the associations of PMPU and NCFs with depression and anxiety symptoms and their interaction effects.

Results

PMPU and lack of close friends significantly increased the risk of depression and anxiety symptoms and the comorbidity of these symptoms in college students (p < 0.001). In addition, the effects of PMPU and lack of close friends on depression and anxiety symptoms in college students were interactive (p < 0.001). No significant sex differences were found.

Conclusion

PMPU and lack of close friends are important risk factors for depression, anxiety, and the comorbidity of these symptoms in college students in China.
Estimating costs of bedside assessment by a judge in each case of mechanical restraint in Germany after new legislation
Authors: Hirsch Sophie , Flammer Erich , Steinert Tilman
Published: January 2024

Background

In 2018, the German Federal Constitutional Court decided that mechanical restraint is the most intrusive coercive measure and its use requires a judge’s decision after bedside assessment if lasting longer than 30 min. Subsequently, legal changes were realized. The objective of our study was to determine the number of saved coercive episodes and saved hours in seclusion or restraint in 2019 compared to the average of the previous years, 2015–2017, as well as costs per saved episode, hour, and case saved from any coercive measure.

Methods

We used data from the Baden–Wuerttemberg case registry for coercive measures, covering all 32 psychiatric hospitals of the Federal State and 435,767 admissions in the study period. Time expenditure was calculated as 3.5 h with an average of 51.95 € per working hour on the side of the justice system and 1.5 h (45.94 €/h) on the side of the hospital per case.

Results

The number of coercive episodes decreased by 10.0% from 28,181 (average 2015–2017) to 25,371 (2019). The number of hours in seclusion or restraint decreased by 17.9% from 321,956 (2015–2017) to 264,423 (2019). This resulted in the cost of 872.33 € per saved episode and 42.61 € per saved hour in seclusion or restraint.

Conclusion

Given the correctness of our estimations, saving 1 h in coercion by less than 1 h of an expert’s work might be justified from an ethical and economic perspective.
Uncovering transcriptomic biomarkers for enhanced diagnosis of methamphetamine use disorder: a comprehensive review
Authors: Jang Won-Jun , Lee Sooyeun , Jeong Chul-Ho
Published: January 2024

Introduction

Methamphetamine use disorder (MUD) is a chronic relapsing disorder characterized by compulsive Methamphetamine (MA) use despite its detrimental effects on physical, psychological, and social well-being. The development of MUD is a complex process that involves the interplay of genetic, epigenetic, and environmental factors. The treatment of MUD remains a significant challenge, with no FDA-approved pharmacotherapies currently available. Current diagnostic criteria for MUD rely primarily on self-reporting and behavioral assessments, which have inherent limitations owing to their subjective nature. This lack of objective biomarkers and unidimensional approaches may not fully capture the unique features and consequences of MA addiction.

Methods

We performed a literature search for this review using the Boolean search in the PubMed database.

Results

This review explores existing technologies for identifying transcriptomic biomarkers for MUD diagnosis. We examined non-invasive tissues and scrutinized transcriptomic biomarkers relevant to MUD. Additionally, we investigated transcriptomic biomarkers identified for diagnosing, predicting, and monitoring MUD in non-invasive tissues.

Discussion

Developing and validating non-invasive MUD biomarkers could address these limitations, foster more precise and reliable diagnostic approaches, and ultimately enhance the quality of care for individuals with MA addiction.

Introduction

Mobile Health (mHealth) is a rapidly growing field of medicine that has the potential to significantly change everyday clinical practice, including in psychiatry. The COVID-19 pandemic and technological developments have accelerated the adoption of telepsychiatry and mobile solutions, but patient perceptions and expectations of mHealth remain a key factor in its implementation.

Aim

The aim of this study was to assess (1) the prevalence, (2) attitudes, preferences and (3) concerns about mobile mental health, including telepsychiatry and self-management tools, among patients with mental disorders over the period 2020–2023, i.e., at the onset, peak and after the expiration of the COVID-19 pandemic.

Materials and methods

A semi-structured survey was administrated to 354 patients with mental disorders in Poland. The questions were categorized into three section, addressing prevalence, attitudes, and concerns about telepsychiatry and mobile health self-management tools. The survey was conducted continuously from May 2020 to the end of May 2023.

Result

As many as 95.7% of patients with mental disorders used mobile devices at least once a week. Over the course of 3 years (from 2020 to 2023), there was a significant increase in the readiness of patients to embrace new technologies, with the percentage rising from 20% to 40%. In particular, a remarkable growth in patient preferences for telepsychiatry was observed, with a significant increase from 47% in 2020 to a substantial 96% in 2023. Similarly, mHealth self-management tools were of high interest to patients. In 2020, 62% of patients like the idea of using mobile apps and other mobile health tools to support the care and treatment process. This percentage also increased during the pandemic, reaching 66% in 2023. At the same time, the percentage of patients who have concerns about using m-health solutions has gradually decreased, reaching 35% and 28% in 2023 for telepsychiatry and for the reliability and safety of m-health self-management tools, respectively.

Conclusion

This study highlights the growing acceptance of modern technologies in psychiatric care, with patients showing increased readiness to use telepsychiatry and mobile health self-management tools, in particular mobile applications, after the COVID-19 pandemic. This was triggered by the pandemic, but continues despite its expiry. In the face of patient readiness, the key issue now is to ensure the safety and efficacy of these tools, along with providing clear guidelines for clinicians. It is also necessary to draw the attention of health systems to the widespread implementation of these technologies to improve the care of patients with mental disorders.

The behavioural variant of Frontotemporal Dementia (bvFTD) is a neurodegenerative condition characterized by behavioural and cognitive symptoms. Mood disturbances, including manic-like episodes, can occur in bvFTD, posing diagnostic and therapeutic challenges. This case report presents a 62-year-old male with bvFTD exhibiting weekly mood fluctuations alternating between manic and depressive-like states. While initial treatment with quetiapine and trazodone showed partial improvement, the periodicity of mood fluctuations persisted. Subsequently, lithium was introduced, resulting in a notable reduction in symptom severity for both manic and depressive episodes. This report highlights the potential use of lithium as a mood stabilizer in bvFTD patients with periodic mood fluctuations, refractory to standard treatments. Further research is needed to elucidate the mechanisms underlying lithium’s efficacy in bvFTD and to establish treatment guidelines.
