UNASSIGNED: This study aimed to examine the latent profile of nurses\' mental workload (MWL) and explore the influencing factors via a person-centred approach.
UNASSIGNED: From March to July 2023, a quantitative cross-sectional study was carried out to investigate 526 Chinese clinical nurses from five tertiary hospitals in Sichuan Province, China, by using demographic information, the Perceived Social Support Scale, Simplified Coping Skill Questionnaire, and NASA-Task Load Index. Latent profile analyses were performed using Mplus 7.3 software. Pearson\'s chi-squared and logistic regression analysis was done using SPSS 24.0 software.
UNASSIGNED: Three profiles of mental workload were identified based on the nurses\' responses to the mental workload assessment, designated as \"low MWL-high self-rated (n = 70, 13.3%)\", \"moderate MWL (n = 273, 51.9%)\", and \"high MWL-low self-rated (n = 183, 34.8%)\". Based on the analysis of the three subtypes, nurses with working years < 5 years (χ 2  = 12.135, P < 0.05), no children (χ 2  = 16.182, P < 0.01), monthly income < 6000 (χ 2  = 55.231, P < 0.001), poor health status (χ 2  = 39.658, P < 0.001), no psychological training in the past year (χ2 = 56.329, P < 0.001) and suffering from workplace violence (χ 2  = 19.803, P < 0.001) were significantly associated with MWL. Moreover, the multivariate logistic regression analysis showed that negative coping styles (OR = 1.146, 95% CI: 1.060-1.238, P = 0.001) were accompanied by higher MWL while negatively associated with perceived social support (OR = 0.927, 95% CI: 0.900-0.955, P < 0.001).
UNASSIGNED: Our results showed that the MWL of nurses could be classified into three subtypes. Monthly income, health status, psychological training, workplace violence, negative coping style, and perceived social support were the factors influencing MWL. Managers can employ personalised intervention strategies according to the individual characteristics of different subgroups to reduce nurses\' MWL.

BACKGROUND: Different degrees of self-transcendence exist in lung cancer patients, which can stimulate patients\' self-awareness and promote them to face negative events in life positively, thus improving patients\' quality of life and treatment outcomes. However, there are few reports on self-transcendence in lung cancer patients in China, and the related influencing factors have not yet been clarified. This study aims to investigate the current situation of self-transcendence in lung cancer patients and explore its risk factors, so as to provide a theoretical basis for clinical intervention decision-making.
METHODS: 243 lung cancer patients who were admitted to the Department of Lung Cancer Center of West China Hospital, Sichuan University from September 2023 to February 2024 were enrolled as the study subjects; general information questionnaire, self-transcendence scale, Herth hope scale and social support scale were used for the investigation. The influencing factors related to self-transcendence of lung cancer patients were analyzed.
RESULTS: The total mean score of self-transcendence in lung cancer patients was (44.73±8.94); the total mean score of hope level was (37.60±4.98), and the total mean score of social support was (41.31±7.27). Self-transcendence was positively correlated with hope level and social support (P<0.001, P<0.001). Education, hope level and social support were influencing factors of self-transcendence in lung cancer patients (P<0.05, P<0.001, P<0.05).
CONCLUSIONS: Self-transcendence in lung cancer patients was at a low level and was influenced by hope level and social support. Healthcare professionals should pay attention to improving the hope level of lung cancer patients, carrying out targeted psychological interventions, and at the same time guiding them to enhance the perception of social support, so as to promote the realization of self-transcendence in patients.

Scientific data sharing (SDS) has become essential for scientific progress, technological innovation and socioeconomic development. Identifying the key influencing factors of SDS can effectively promote SDS programmes and give full play to the critical role of scientific data. This study used grounded theory and information ecology theory to construct an SDS influencing factor model that encompassed five dimensions and 28 influencing factors and followed the fuzzy decision-making trial and evaluation laboratory (fuzzy-DEMATEL) approach to measure and analyse the degree of influence of each influencing factor and identify the key factors. The results show that (1) there are interactions and mutual interactions between the various influencing factors of SDS, which can form a complex network system. (2) 16 influencing factors, such as data-sharing policies, data-sharing regulations and data-sharing standards, comprise the key influencing factors in SDS. (3) The optimisation path of SDS is \'Scientific Researchers\' → \'Scientific Data\' → \'Policy Environment\' → \'Research Organisations → \'Information Technologies\'. In this regard, we proposed the following management suggestions to promote the development of SDS programmes in China: focusing on researchers\' subjective willingness to share, enhancing the integrated governance of scientific data, fulfilling the role of policy support and guidance, strengthening the support of research organisations and improving SDS platforms with information technology.

This study conducted dynamic triaxial tests on a typical poured asphalt concrete material of core walls in Xinjiang, exploring the dynamic characteristics of poured asphalt concrete under various confining pressures, principal stress ratios, and vibration frequencies. On this basis, the dynamic constitutive relationship of poured asphalt concrete was investigated using the Hardin-Drnevich model. The results indicate that under different confining pressures, principal stress ratios, and vibration frequencies, the variation patterns of the backbone lines of dynamic stress-strain of poured asphalt concrete are basically identical, consistent with a hyperbolic curve. The confining pressure and principal stress ratio significantly affect the backbone line of dynamic stress-strain. By comparison, frequency has a minimal effect. The changing trends of dynamic elasticity modulus and damping ratio of poured asphalt concrete under various factors are almost the same. When the material has high dynamic stress and strain, the hysteresis loop is large. When the curve of the damping ratio becomes flat, the asymptotic constant can be used as the maximum damping ratio. The relationship between the reciprocal of the dynamic elasticity modulus and the dynamic strain of poured asphalt concrete exhibits a linear distribution. Under different ratios of confining pressure to principal stress, there are large discrepancies between the calculated values from the formula and the experimental fitting values of the maximum dynamic elasticity modulus, and the maximum relative errors reach 16.65% and 18.15%, respectively. Therefore, the expression for the maximum dynamic elasticity modulus was modified, and the calculated values using the modified formula were compared with the experimental fitting values. The relative errors are significantly reduced, and the maximum relative errors are 3.02% and 2.04%, respectively, in good agreement with the fitting values of the experimental data. The findings of this article render a theoretical basis and reference for the promotion and application of poured asphalt concrete.

BACKGROUND: The severity and treatment response of acne, melasma, and rosacea may be influenced by various currently unclear internal and external factors. This study aimed to provide evidence to the influencing factors for the mentioned conditions through a real-world case-control study.
METHODS: An online survey consisting of 60 questions was implemented, collecting information on demographics, socioeconomics, genetic factors, lifestyle habits, environmental exposures, and skin care behaviors. Then we constructed univariate and multivariate logistic regressions. Furthermore, we analyzed the dose-response relationship between exposure and outcome.
RESULTS: A total of 399 individuals, including 94 acne patients, 107 melasma patients, and 91 rosacea patients were included. Acne and melasma were positively correlated with screen time (acne: odds ratio [OR]: 2.24, 95% confidence interval [CI]: 1.25-4.02; melasma: OR: 1.59, 95% CI: 1.09-2.31), while exercise exerted a protective effect on both acne (OR: 0.31, 95% CI: 0.13-0.77) and melasma (OR: 0.42, 95% CI: 0.22-0.80) in a dose-response relationship. In addition, males were associated with an elevated risk of acne (OR: 6.62, 95% CI: 1.01-43.26). Aging (OR: 1.15, 95% CI: 1.07-1.24) and irregular bowel movements (OR: 2.99, 95% CI: 1.11-8.08) were independent risk factors for melasma. Rosacea was positively associated with BMI (OR: 1.17, 95% CI: 1.01-1.35).
CONCLUSIONS: In our study, we highlighted exercise as an independent protective factor for both acne and melasma in a dose-response trend. Inversely, extended use of electronic equipment was independently associated with higher risks of acne and melasma. Rosacea, however, was more likely to be related with BMI.

UNASSIGNED: Emergency medical services (EMS) provide health care in situations with limited time and resources. Challenges arise when introducing novel medications, treatments, or technologies or modifying existing practices in these settings. Effective implementation strategies are pivotal for their success. This study aims to identify and categorize potential facilitators and barriers in the implementation of prehospital EMS through a review of relevant research articles.
UNASSIGNED: We searched PubMed and EMbase to identify studies published before December 2023, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for our search strategy and scoping review. We included original articles written in English that report on the factors that influence the implementation in prehospital settings. We extracted and categorized the factors into different themes.
UNASSIGNED: Out of the 371 retrieved papers, we selected 19 (5%) for inclusion in this review. We extracted 46 influencing factors from the selected articles and categorized them into ten themes: (1) Outer system, (2) Inner system, (3) Practitioner characteristics, (4) Resources, (5) Communication and collaboration, (6) Patient factors, (7) Intervention characteristics, (8) De-implementation of prior practices, (9) Logistical issues, and (10) Quality improvement.
UNASSIGNED: This study examined the literature on EMS implementation factors and proposed a 10-theme EMS model framework. Key factors include training/education, equipment/tools, communication with hospitals, and practitioners\' attitudes.

The unprecedented rapid growth of digital health has brought new opportunities to the health field. However, elderly patients with chronic diseases, as an important potential beneficiary group, are affected by the digital divide, leading to unsatisfactory usage of digital health technologies (DHTs). Our study focused on the factors influencing the adoption of DHTs among this vulnerable group. To extend the UTAUT theory, technology anxiety and several demographic predictors were included to address the age characteristics of the respondents. An on-site survey was conducted in general, district, and community hospitals in Shanghai (n = 309). Facilitating conditions negatively influenced technology anxiety. Technology anxiety hindered behavioural intention. Social influence had a significant but negative impact on behavioural intention. Education, whether older adults have had experience with DHTs and previous smartphone usage experiences were significantly associated with technology anxiety. The findings provide valuable information for multiple stakeholders, including family members of elderly users, product designers, and policymakers. Ameliorating facilitating conditions, improving devices\' usage experience, encouraging attempts and focusing on groups with lower educational levels can help to reduce technology anxiety and promote DHT acceptance and use in older age groups.

OBJECTIVE: This study aimed to investigate the incidence and severity of surgical fear in patients with oral and maxillofacial tumors.
METHODS: The survey participants were composed of patients with oral and maxillofacial tumors, who were scheduled to undergo surgery. A general information questionnaire, the Surgical Fear Questionnaire (SFQ), the Patient Health Questionnaire (PHQ)-9, and the Generalized Anxiety Disorder (GAD)-7 score were used for the investigation.
RESULTS: A total of 203 patients were investigated. Among them, 85.22% had fear of surgery. The median score of SFQ was 20, and the quartile was (6, 36). The patients were categorized into none, mild, moderate, and severe groups according fear level. Gender, diabetes, obvious discomfort before surgery, PHQ-9, and GAD-7 scores were the variables with statistical difference in each fear level. Multifactor analysis showed that women were more likely to have moderate and severe fear than men (OR=2.19, P=0.03; OR=2.72, P=0.01), patients with obvious preoperative discomfort symptoms were more inclined to have no fear (OR=4.73, P=0.02), and patients with diabetes were more likely to have severe fear (OR=3.33, P=0.02). The incidence rates of depression and anxiety were 31.03% and 24.63%, respectively. The incidence of anxiety and depression in patients with severe fear was 40.00%. Surgical fear was moderately positively correlated with anxiety (r=0.491, P<0.001) and depression (r=0.514, P<0.001).
CONCLUSIONS: The fear of surgery in patients with oral and maxillofacial tumors is common and distributed in all levels. Medical staff can screen and assess patients with moderate and severe fear of surgery in accordance with the influencing factors and implement targeted interventions to reduce fear of surgery, anxiety, and depression on the basis of the source of fear.

Malus sieversii, commonly known as wild apples, represents a Tertiary relict plant species and serves as the progenitor of globally cultivated apple varieties. Unfortunately, wild apple populations are facing significant degradation in localized areas due to a myriad of factors. To gain a comprehensive understanding of the nutrient status and spatiotemporal variations of M. sieversii, green leaves were collected in May and July, and the fallen leaves were collected in October. The concentrations of leaf nitrogen (N), phosphorus (P), and potassium (K) were measured, and the stoichiometric ratios as well as nutrient resorption efficiencies were calculated. The study also explored the relative contributions of soil, topographic, and biotic factors to the variation in nutrient traits. The results indicate that as the growing period progressed, the concentrations of N and P in the leaves significantly decreased (P < 0.05), and the concentration of K in October was significantly lower than in May and July. Throughout plant growth, leaf N-P and N-K exhibited hyperallometric relationships, while P-K showed an isometric relationship. Resorption efficiency followed the order of N < P < K (P < 0.05), with all three ratios being less than 1; this indicates that the order of nutrient limitation is K > P > N. The resorption efficiencies were mainly regulated by nutrient concentrations in fallen leaves. A robust spatial dependence was observed in leaf nutrient concentrations during all periods (70.1-97.9% for structural variation), highlighting that structural variation, rather than random factors, dominated the spatial variation. Nutrient resorption efficiencies (NRE, PRE, and KRE) displayed moderate structural variation (30.2-66.8%). The spatial patterns of nutrient traits varied across growth periods, indicating they are influenced by multifactorial elements (in which, soil property showed the highest influence). In conclusion, wild apples manifested differentiated spatiotemporal variability and influencing factors across various leaf nutrient traits. These results provide crucial insights into the spatiotemporal patterns and influencing factors of leaf nutrient traits of M. sieversii at the permanent plot scale for the first time. This work is of great significance for the ecosystem restoration and sustainable management of degrading wild fruit forests.

OBJECTIVE: To investigate the incidence of fear of cancer recurrence in patients with digestive tract cancers analyse its influencing factors, and further establish a visual risk prediction model.
METHODS: A cross-sectional study.
METHODS: A cross-sectional survey was conducted among 570 patients with digestive tract tumours admitted to a local hospital, from May 2023 to December 2023 by convenient sampling method. Univariate analysis and logistic analysis were performed on the influencing factors, and the risk prediction nomogram model of fear of cancer recurrence in patients with digestive tract cancer was constructed by using R 4.1.3 software. ROC curve was used to evaluate the differentiation of the nomogram model. The calibration curve and Hosmer-Lemeshow goodness of fit test were used to evaluate the consistency of the model. This study was reported using the TRIPOD checklist.
RESULTS: In this study, 272 (47.7%) patients developed fear of recurrence. The risk prediction model of recurrence fear column chart for digestive tract cancer patients incorporated six variables of gender, therapy, alimentary tract haemorrhage, pain, depression and social support. The C-statistic was (.976), and the calibration curve showed that the predicted probability was more in line with the actual probability of occurrence, and the decision curve showed that the predictive model had better practicality.
CONCLUSIONS: The column-line diagram prediction model constructed in this study is effective and facilitates timely intervention and management by healthcare professionals based on their risk factors.
CONCLUSIONS: Nomogram is helpful to calculate the risk probability of FCR in patients with digestive tract cancer, identify FCR patients in time, and formulate comprehensive and personalized countermeasures, to provide a good quality of life and prolong the survival cycle of patients with digestive tract cancer.
UNASSIGNED: Participants were hospitalized patients or patients with digestive tract cancer undergoing follow-up. First of all, before the investigation and research, a team is formed to discuss the concept, research purpose, method, significance, etc., and determine the research tools. Second, by reasonably explaining the study to patients to seek informed consent from the patient and sign it, patients filled in the questionnaire independently. For patients with low education levels who could not fill in the questionnaire, the team members made objective explanations to help them choose reasonable options.
