The COVID-19 outbreak led to widespread school closures and the shift to remote teaching, potentially resulting in lasting negative impacts on teachers’ psychological well-being due to increased workloads and a perceived lack of administrative support. Despite the significance of these challenges, few studies have delved into the long-term effects of perceived instructional leadership on teachers’ psychological health. To bridge this research gap, we utilized longitudinal data from 927 primary and secondary school teachers surveyed in two phases: Time 1 in mid-November 2021 and Time 2 in early January 2022. Using hierarchical linear modeling (HLM), our findings revealed that perceptions of instructional leadership, especially the \"perceived school neglect of teaching autonomy\" at Time 1 were positively correlated with burnout levels at Time 2. Additionally, burnout at Time 2 was positively associated with psychological distress and acted as a mediator between the \"perceived school neglect of teaching autonomy\" and psychological distress. In light of these findings, we recommend that schools prioritize teachers’ teaching autonomy and take proactive measures to mitigate burnout and psychological distress, aiming for the sustainable well-being of both teachers and students in the post-pandemic era.

Background In recognizing the need for a reliable and valid instrument to assess psychological distress among children and adolescents, the present study translated the newly developed Depression Anxiety Stress Scale for Youth (DASS-Y) into Chinese, while also comparing its psychometric properties with those of the well-established DASS-21 within a primary and middle school demographic. Methods Utilizing a combination of convenience sampling and purposive sampling, a cohort comprising 1,507 primary and 1,131 middle school students was recruited. Rasch analysis, confirmatory factor analysis (CFA), and structural equation modeling (SEM) were used in the data analysis. Results Significant differences were observed between the DASS-Y and the DASS-21, notably within the anxiety subscale. The proportions of individuals with clinical mood disorders identified by the two scales demonstrated a significant disparity. Both scales, following an adjustment of responses, exhibited satisfactory internal consistency and convergent validity, with the acceptance of a three-factor structure. Furthermore, the DASS-Y showed superior discriminant validity relative to the DASS-21, providing more compelling evidence regarding concurrent validity. Conclusion Overall, the Chinese version of the DASS-Y demonstrated superior robustness to the DASS-21 in terms of psychometric properties. The findings provide initial evidence for the psychometric properties of the DASS-Y from another culture.

Background The COVID-19 pandemic’s “Great Online Transition” significantly impacted teachers. Existing research on Emergency Remote Teaching (ERT) lacks longitudinal designs and consideration of subject-specific contexts. This study, using the Stressor-Strain-Outcome framework, investigates psychological needs thwarting (PNT) during ERT on teachers’ well-being and online teaching intentions, considering subject of instruction as a potential factor. Methods Data were collected from 1,369 Chinese primary and middle school teachers of Chinese literature, mathematics, and English as a Foreign Language (EFL) at two time points: two weeks after ERT implementation (Time 1, mid-November 2021) and two months later, after returning to face-to-face teaching (Time 2, mid-January 2022). PNT, emotional exhaustion, psychological distress, and intention towards online teaching were evaluated. Results Among the types of PNT, competence thwarting emerged as the strongest predictor of emotional exhaustion, which was, in turn, associated with reduced online teaching intention and increased psychological distress. EFL teachers showed stronger associations between PNT, emotional exhaustion, and adverse outcomes, indicating higher susceptibility to strain during ERT. Conclusion Subject of instruction, particularly for EFL teachers, significantly influences the relationship between PNT and teacher outcomes during ERT. Our findings underscore the need for subject-specific support strategies in online teaching environments.

Utilizing a large-scale cross-sectional survey, the present study tested the advanced psychometric properties of Fear of COVID-19 Scale (FCV-19S) in specific populations (i.e., primary and middle schoolteachers, and their students). The present study also examined the association between perceived fear of COVID-19 and psychological distress among home-room teachers (i.e., teachers who teach all their students in one classroom all day) and their students. The results among participants (11,134 teachers and 4,335 students) indicated good internal reliability of FCV-19S and excellent factorial validity with a two-factor structure utilizing these specific populations. Furthermore, the multilevel analysis showed that home-room teachers’ psychological distress, but not fear of COVID-19, was positively associated with their students. In sum, the FCV-19S is a useful tool to assess the fear of COVID-19 on potentially vulnerable populations (i.e., primary/middle schoolteachers and their students). Future studies are encouraged to use the present study’s findings to investigate possible underlying mechanisms for developing effective coping strategies and interventions.

During transitional periods, college freshmen may experience mental health issues. The Depression, Anxiety, and Stress Scale—21-item version (DASS-21) is commonly used for mental health assessment in China. However, evidence is lacking regarding its applicability with freshmen as a demographic. Debates also exist regarding its factor structure. This study aimed to evaluate the DASS-21′s psychometric properties with Chinese college freshmen and investigate its association with three kinds of problematic Internet use. A convenience sampling method was used to recruit two samples of freshmen—one of 364 (female 248; mean age 18.17 years) and the other of 956 (female 499; mean age 18.38 years) participants. McDonald’s ω and confirmatory factor analysis were conducted to evaluate both the scale’s internal reliability and construct validity. The results indicated acceptable reliability, with a one-factor structure inferior to a three-factor structure in terms of model fit. Furthermore, it was demonstrated that problematic Internet use was significantly and positively associated with depression, anxiety, and stress among Chinese college freshmen. Based on the prerequisite of measurement equivalence across two samples, the study also found that freshmen’s problematic Internet use and psychological distress were likely to be affected by the strict measures put in place during the COVID-19 pandemic.

Toxoplasma gondii is a protozoan parasite that is responsible for approximately 24% of all estimated deaths attributed to foodborne pathogens in the United States. Human infection results from accidental ingestion of oocysts from the environment, in water, or on insufficiently washed produce or from consumption of raw or undercooked meat products that contain T. gondii tissue cysts. This review focused on studies of T. gondii in meat because many human T. gondii infections are acquired through consumption of raw or undercooked meat. Prevalence of T. gondii is higher in conventionally reared pigs, sheep, and poultry than in cattle and is greater in meat products from organic than from conventionally reared meat animals because of outdoor access, which poses substantially greater opportunities for exposure to infected rodents, wildlife, and oocyst-contaminated feed, water, or environmental surfaces. Risk factors related to T. gondii exposure for livestock include farm type, feed source, presence of cats, methods of rodent and bird control, methods of carcass handling, and water quality. This review serves as a useful resource and information repository for informing quantitative risk assessment studies for T. gondii infection in humans through meat consumption.

In multiple system atrophy (MSA), the α-synuclein protein misfolds into a self-templating prion conformation that spreads throughout the brain, leading to progressive neurodegeneration. While the E46K mutation in α-synuclein causes familial Parkinson’s disease (PD), we previously discovered that this mutation blocks in vitro propagation of MSA prions. Recent studies by others indicate that α-synuclein adopts a misfolded conformation in MSA in which a Greek key motif is stabilized by an intramolecular salt bridge between residues E46 and K80. Hypothesizing that the E46K mutation impedes salt bridge formation and, therefore, exerts a selective pressure that can modulate α-synuclein strain propagation, we asked whether three distinct α-synuclein prion strains could propagate in TgM47 +/- mice, which express human α-synuclein with the E46K mutation. Following intracranial injection of these strains, TgM47 +/- mice were resistant to MSA prion transmission, whereas recombinant E46K preformed fibrils (PFFs) transmitted neurological disease to mice and induced the formation of phosphorylated α-synuclein neuropathology. In contrast, heterotypic seeding following wild-type (WT) PFF–inoculation resulted in preclinical α-synuclein prion propagation. Moreover, when we inoculated TgM20 +/- mice, which express WT human α-synuclein, with E46K PFFs, we observed delayed transmission kinetics with an incomplete attack rate. These findings suggest that the E46K mutation constrains the number of α-synuclein prion conformations that can propagate in TgM47 +/- mice, expanding our understanding of the selective pressures that impact α-synuclein prion replication.

Purpose: Mattering is essential to university students, mental health. Feeling valued by others or unimportant can affect their overall well-being. However, most measures for assessing mattering have been developed and tested in Western countries, with limited evaluation of the measures when administered to university students in other regions. This study evaluated the reliability and validity of three mattering-related instruments--the General Mattering Scale (GMS), Anti-Mattering Scale (AMS), and Fear of Not Mattering Inventory (FNMI) among Chinese university students using classical test theory and Rasch analysis. Methods: The study comprised 3594 university students from 19 universities across 13 provinces in mainland China, with a balanced gender distribution of 47.2% females and 52.8% males. Participants, ages ranged from 18 to 37, averaging 20.02 years. Most (78.4%) were in four-year programs, with the rest in three-year programs. The majority were freshmen (54.2%), and 86.3% had siblings. The predominant major was engineering (43.4%), followed by roughly equal representations in science, social science, and literature/art. Results: The three scales showed high reliability and factorial validity, with Rasch analysis confirming their unidimensionality and monotonicity, although 2 of 15 items (one GMS item and one FNMI item) had lower fit. There were no substantial differences in item functioning between male and female respondents. Further analyses indicated that mattering, anti-mattering, and fear of not mattering all explained significant unique variance in levels of hope and distress. Conclusion: All three mattering-related instruments are suitable for assessing Chinese students' mattering, anti- mattering, and fear of not mattering and changes in levels of these mattering dimensions. Moreover, each measure represents a unique element of the mattering construct in terms of associations with levels of hope and distress assessed in during the COVID-19 pandemic. Keywords: mattering, anti-mattering, fear of not mattering, university students, hope, distress

Background Central nervous system tumours affecting the brain and spine are the most common solid tumour site in the paediatric population and the most common causes of cancer death in children and young people. They are associated with high morbidity both from the tumour and the interventions used to treat them. Postoperative morbidity reporting following surgery for paediatric brain tumours is poor. This is due to variability of outcomes measured and reported and the lack of a common language when reporting adverse outcomes. One solution is to develop a core outcome set which will stipulate the minimum postoperative outcomes that should be reported. The COMBAT (Core Postoperative Morbidity Set for Paediatric Brain Tumours) Project will develop a core set of adverse outcomes that can be applied to paediatric brain tumour patients undergoing surgery. Methods and analysis This protocol has been developed using the COS-STAD (Core Outcome Set-Standards for Development) recommendations and the COS-STAP (Core Outcome Set-STAndardised Protocol Items) statement. A systematic review will identify adverse outcomes reported in the literature and how they are measured. Outcomes of importance to patients and their carers will be identified from semi-structured qualitative interviews with patients and their carers from Alder Hey Children’s Hospital, Liverpool, UK. Consensus on the most important harms will be sought using a two-round eDelphi survey completed by national and international participants including health professionals, researchers, patients and their carers. Results of the eDelphi survey will be assessed against a pre-defined definition of consensus and discussed at an international consensus meeting attended by participants of the eDelphi survey. Discussion There is a clear need for a common language to harmonise measurement and reporting of morbidity following surgery for paediatric brain tumour patients. This project will define postoperative adverse outcomes that are of critical importance to key stakeholders. It will standardise surgical morbidity outcome measurement and reporting in both research studies and routine clinical practice, enabling comparison across different trials, studies and clinical services. It will lay the groundwork for future research in paediatric brain tumour surgical morbidity.
