This study aimed (a) to evaluate the spatiotemporal gait variables of total knee arthroplasty (TKA) before (pre-) and after the procedure (post-), and (b) to investigate the influence of the surgical side on these variables. Twenty-one volunteers (13 females and 8 males) participated, undergoing assessments pre-surgery and nine to 12 months post-surgery. Clinical tests indicated significant reductions in knee pain and improvements in active and passive extension post-surgery. TKA resulted in decreased pain, extension deficits, and functional assessments, with lower scores on the WOMAC questionnaire. A gait analysis showed post-surgery improvements in gait speed (5.8%), cycle time (−4.8%), step time (4.4%), double limb support time (−11.1%), step (4.4%) and stride (6.3%) lengths, and step (5.1%) and stride (5.0%) cadences. Comparisons between surgical side and limb dominance indicated significant differences in gait speed, stance, swing and step times, double limb support time, step and stride lengths, and step cadence. The non-dominant limb demonstrated greater improvements across most parameters compared to the dominant limb. These findings emphasize the importance of considering the limb dominance of patients with knee osteoarthritis when evaluating post-TKA function. These conclusions can be helpful for personalized rehabilitation programs, allowing tailored interventions for individuals undergoing knee surgery. Full article

Despite the increasing prevalence of pet ownership in Chinese societies, standardized tools to assess grief from pet loss remain lacking. Research predominantly focuses on Western populations, creating a gap in understanding pet bereavement in Chinese cultural settings. This study aimed to adapt and validate the Pet Bereavement Questionnaire (PBQ-C) for a Chinese context to create a culturally appropriate assessment tool. A total of 246 participants with companion animal loss experiences were recruited through the university of the research team. They were invited to complete an online survey including the PBQ-C, the Depression subscale of the Depression Anxiety Stress Scales (DASS-21), and the Inventory of Complicated Grief (ICG). Both Exploratory Factor Analysis and Confirmatory Factor Analysis were conducted to examine the psychometric properties of the PBQ-C and the findings supported a three-factor structure—grief, anger, and guilt—aligned with the original PBQ, with three items reassigned to different factors. Despite these adjustments, the PBQ-C demonstrated strong internal consistency, reflecting the reliability of the questionnaire in measuring the same construct across its items; split-half reliability, indicating its ability to produce consistent results when divided into two parts; and concurrent validity, showing that the PBQ-C correlates well with other established measures of grief. The validated PBQ-C provides a culturally sensitive tool for assessing pet bereavement in Chinese society that can promote research and counselling support for this under-researched and under-recognized type of loss of human-animal relationships.

There is a need to reduce human–wildlife conflicts in the area around Liupanshan Nature Reserve in Ningxia Hui Autonomous Region, China. This study investigated the financial losses caused by wild boar and their causes. A questionnaire investigation (n = 135) and a field test were conducted, which included 108 sample lines and 97 infrared cameras. A principal component analysis and generalised linear model was used to analyse the importance of the effect of the factors on wild boar damage. Based on an estimate of 17,049 wild boars in the study area, we found that in the agricultural land owned by the residents, the boar density of each county and distance from the village to the nature reserve were the most significant factors that affected crop damage. Then, financial losses in spring, summer, and autumn had a moderate effect on financial loss, and the crop type had the lowest effect. We recommend reducing the wild boar population by increasing leisure hunting and the number of leopards. Additionally, a focus on farmland protection is a practical way to prevent wild boar invasions. Meanwhile, it is also necessary to conduct long-term monitoring of wild boar population status and manage the relationship between the government, research teams, and local people to more efficiently and comprehensively reduce conflicts between humans and wild boars.

Fish provide energy, protein, and other important nutrients, including n-3 fatty acids, vitamin D, and iodine. However, some species of fish could contain contaminants such as mercury and dioxins. The aim of the study was to assess the frequency of fish consumption in Poland, including of sea and freshwater fish species, referring to some socio-economic determinants. The frequency of consumption was assessed using Food Propensity Questionnaire data from 1489 adults (722 males, 767 females) in 2019–2020. The fish consumption frequency in Polish adults was lower than the recommendation (at least twice a week). About 80% of respondents consumed fish less frequently than recommended. Sea fish were mostly consumed less than once a month (31.8%) or 1–3 times a month (30.9%). Most subjects (44.8%) consumed freshwater fish less than once a month. Consumption also depended educational level, economic status, place of residence, declared health status, and BMI value or BMI status. However, taking into account sex, the occurrence of these relationships was different between men and women. It seems that educational activities and dissemination of proper nutrition principles is necessary in order to increase the consumption of fish in Poland. It is important to emphasize the health benefits of fish consumption in relation to the possible adverse effects of their contamination. Full article

Most individuals in the general population will be exposed to potentially traumatic situations at some point in their lifespan. There is a strong body of research focusing on the clinical implications of exposure to potentially traumatic situations, but less attention has been given to psychological adjustment following these events. Very few available instruments assess trauma exposure while considering subjective perceptions of both positive and negative features. In this study, 304 adults from the general population, mostly women of middle and high socioeconomic status (mean age = 43), filled in a questionnaire with sociodemographic questions and an adapted version of the Trauma Exposure Checklist, which was originally developed in the context of the COVID-19 pandemic. Results indicate that most participants have experienced a potentially traumatic event, most prevalently related to violence and/or criminality and to the severe illnesses and deaths of close relatives. Principal components and reliability analyses lent support to a three-factor structure that considers perceptions of internal and external losses and a positive factor that addresses resources and social support. This study is a first step towards advancing our knowledge on the impact of developmental and sociodemographic factors on subjective experiences of psychological crises and, consequently, psychological adjustment throughout the lifespan.

Objectives: This study sought to understand the levels of vitamin K in the mature milk of Chinese lactating mothers, thereby providing a foundation for the development of appropriate intake (AI) of vitamin K for infants aged 0–5 months. Methods: Five hundred healthy lactating mothers were selected from the mature milk bank established by the Chinese Maternal and Infant Nutrition and Health Cohort by using a simple random sample procedure. Relevant information about lactating mothers and their infants was obtained by a questionnaire survey. Vitamin K1 and vitamin K2 (MK-4 and MK-7) in mature milk were determined by liquid chromatography–tandem mass spectrometry. Results: The total concentration of vitamin K in mature milk was 4.50 (2.85–6.33) ng/mL. The concentrations of vitamin K1, vitamin K2, MK-4, and MK-7 were 2.81 (1.66–4.39) ng/mL, 1.37 (0.75–2.11) ng/mL, 1.20 (0.58–1.97) ng/mL, and 0.13 (0.08–0.19) ng/mL, respectively. The concentration of vitamin K1 was highest and the concentration of MK-7 was lowest. The concentrations of vitamin K2 and MK-4 in mature milk from the south were significantly higher than those in mature milk from the north. The total vitamin K, vitamin K2, and MK-4 concentrations in mature milk of lactating mothers residing in urban areas were higher than those in rural areas. There was a tendency for the concentration of total vitamin K and vitamin K1 to increase with the mother’s age. Moreover, the concentration of MK-4 in mature milk was highest in summer, followed by spring and winter. The levels of vitamin K1 and MK-4 in mature milk were found to be affected by lactation stage; they were highest at 91–120 days and lowest at 31–60 days. Conclusions: Based on the concentration of vitamin K in mature milk found in this study, it is recommended that the appropriate intake of VK for Chinese infants aged 0–5 months is 3.49 μg/d (2.18 μg/d for VK1 and 1.06 μg/d for VK2).

Background: A short and easy questionnaire is needed to identify symptoms of listening difficulties (LiD) at an early stage. This study aimed to evaluate the utility of such a questionnaire for adolescents with and without LiD. Methods: We included adolescents with and without LiD and adults without LiD in this study. We utilized a questionnaire designed for individuals with LiD, which combined the Speech, Spatial, and Quality of Hearing scales (SSQ)-12 and four additional psychological items. From this, we selected three items that exhibited the largest differences between adolescents with and without LiD. We subsequently examined the relationship between the total scores of all items and the three selected items to develop the short questionnaire. Results: The responses of adolescents to the questionnaire were consistent with those of adults. The total scores from the three selected items exhibited a strong correlation with the overall questionnaire score for adolescents both with and without LiD, indicating their potential for identifying LiD symptoms. Conclusions: The wide implementation of the short questionnaire developed in this study could lead to the early detection of potential LiD symptoms and timely intervention. Full article

With their potential for high returns and expanding role in the financial landscape, cryptocurrency investments have garnered the attention of the financial press and investors. Applying an integrated research model based on the Unified Theory of Acceptance and Use of Technology (UTAUT), this study investigates the factors influencing individual investors’ attitudes toward cryptocurrency investments and their intention to continue investing. The model incorporates constructs such as performance expectancy, effort expectancy, social influence, perceived risk, perceived privacy, technology competency, perceived enjoyment, and prior experience. Data from 506 cryptocurrency investors located in the United States were collected through a 50-item questionnaire. The findings indicate that performance expectancy and perceived enjoyment positively impact attitudes toward cryptocurrency investments, which, in turn, influence the intention to continue investing. Perceived privacy positively affects performance expectancy, while technology competency enhances effort expectancy. These results offer valuable insights for policymakers and cryptocurrency exchanges to foster sustainable growth in the cryptocurrency market. Despite its contributions, the study acknowledges limitations, including a focus on current investors in the US and the exclusion of factors such as optimism and innovativeness. Future research should explore these aspects across different populations and regions to gain a more comprehensive understanding of cryptocurrency investment behavior. Full article

Background/Objectives: The adverse effects of cancer and the long-term sequelae of associated treatments result in reduced quality of life and increased mortality for patients. Supporting patients with cancer to mitigate adverse outcomes is an important aspect of oncology care and the primary purpose of cancer rehabilitation. A retrospective service evaluation was conducted to evaluate the effectiveness of the core iCan patient-centred cancer rehabilitation service. Methods: At the beginning and end of a five-week programme, a series of questionnaires evaluating changes in mental health and wellbeing, and physical activity performance/attitudes, and functional capacity were administered to participants. Results: Following iCan, we found that functional capacity was improved (30 s sit-to-stand: +6.3 repetition; d = −1.00, p < 0.001) and that self-reported physical activity was increased (~1173 MET-mins/wk; d = −0.76, p < 0.001); participants also perceived greater capability, opportunity, and motivation to be active. Mental wellbeing was also improved (SWEMWBS: d = −0.69, p < 0.001), whilst fatigue was reduced (FACIT: d = −0.77, p < 0.001). Conclusion: It appears that iCan has beneficial effects upon the physical/functional and psychological health of its participants. Where data are available, there appear to be clinically significant improvements across the range of measured functional, wellbeing, and activity/sedentariness outcomes, which suggest that participation in iCan is instrumental in adding value to the health and wellbeing of patients.

Anger impairs a driver’s control and risk assessment abilities, heightening traffic accident risks. Constructing a multimodal dataset during driving tasks is crucial for accurate anger recognition. This study developed a multimodal physiological -vehicle driving dataset (DPV-MFD) based on drivers’ self-reported anger during simulated driving tasks. In Experiment 1, responses from 624 participants to anger-inducing videos and driving scenarios were collected via questionnaires to select appropriate materials. In Experiments 2 and 3, multimodal dynamic data and self-reported SAM emotion ratings were collected during simulated and real-vehicle tasks, capturing physiological and vehicle responses in neutral and anger states. Spearman’s correlation coefficient analysis validated the DPV-MFD’s effectiveness and explored the relationships between multimodal data and emotional dimensions. The CNN-LSTM deep learning network was used to assess the emotion recognition performance of the DPV-MFD across different time windows, and its applicability in real-world driving scenarios was validated. Compared to using EEG data alone, integrating multimodal data significantly improved anger recognition accuracy, with accuracy and F1 scores rising by 4.49% and 9.14%, respectively. Additionally, real-vehicle data closely matched simulated data, confirming the dataset’s effectiveness for real-world applications. This research is pivotal for advancing emotion-aware human–machine- interaction and intelligent transportation systems. Full article

Background: With an aging population and the continuous advancement of smart technology, the Chinese government is exploring smart elderly care models to address the challenges posed by aging. Although smart home systems are viewed as a promising solution, their adoption rate among older people remains low. Objectives: This study aimed to investigate the factors influencing the behavioral intention to use smart home systems among older people in Linyi City, Shandong Province, China. Methods: A literature review revealed a lack of quantitative research on older people’s behavioral intention toward smart home systems based on the Innovation Diffusion Theory. This study developed an extended model based on the Innovation Diffusion Theory, Technology Acceptance Model, and external variables, incorporating eight variables: intergenerational technical support, perceived cost, self-reported health conditions, compatibility, observability, trialability, perceived usefulness, perceived ease of use, and behavioral intention. Results: Analysis of 387 valid questionnaires showed that compatibility and trialability significantly and positively affect perceived ease of use, while self-reported health conditions, perceived ease of use, and perceived usefulness have significant effects on behavioral intention. In addition, perceived cost had a negative influence on behavioral intention. Contributions/Significance: These findings highlight the importance of considering these factors in the design of smart home systems to improve user experience and provide valuable practical guidance to smart home system developers, R&D institutions, and policymakers.

Background/Objectives: Pain is a multidimensional experience influenced by sensory, emotional, and cognitive factors. Traditional pain assessments often fail to capture this complexity. This study aimed to develop and validate the Pain Multidimensional Questionnaire (Pa-M-QU), a new self-report tool designed to assess pain catastrophizing, sensitivity, and coping strategies. Methods: Two independent samples of Italian-speaking participants, aged 18 and above, were recruited online. The first sample (n = 392; mean age = 29.36) was used for exploratory factor analysis (EFA), and the second sample (n = 123; mean age = 28.0) for confirmatory factor analysis (CFA). Pearson’s correlations and convergent validity analyses were conducted. Results: From an initial pool of 59 items identified through focus group discussions, 35 items were removed based on reliability analysis. The final 24-item Pa-M-QU features a three-factor structure: catastrophizing, pain sensitivity, and coping with pain. Conclusions: The Pa-M-QU offers a rapid, non-invasive assessment that captures the multidimensional nature of pain. It is a starting point to develop tools for both clinical and research settings, aiding in evaluating pain in healthy individuals and predicting acute and chronic pain disorders. Future research should focus on refining the Pa-M-QU for broader clinical applications and exploring its potential to complement or replace traditional pain assessments, thereby advancing pain management and research.

Afforestation (AF) in farmland has been widely used as an alternative and sustainable land-use practice to address socioeconomic and environmental challenges. The aim of this study is to estimate farmers’ willingness to accept (WTA) compensation and land, both of which are equally significant for policymakers to ensure the effective implementation of AF and achieve desired outcomes. This topic has not been sufficiently explored in previous research. This study focused on areas characterized by insecure farming conditions, backward economies, and fragile landscapes, where farmers are generally unfamiliar with AF or compensation for ecosystem services under payment for ecosystem services programs. It assessed their attitudes towards the WTA AF, compensation, and land as an alternative practice, which remains under-researched. This is crucial for designing effective AF programs in the future to improve livelihood and enhance the quantity and quality of the environment. This study used the contingent valuation method to estimate the minimum WTA compensation and maximum land for the forgone loss and alternative land-use practices. A questionnaire survey was conducted in Hupsekot municipality, Nepal, with 232 farmer households. The ordinal logistic regression model was used to analyze influencing factors of WTA compensation and land. The result showed that farmers’ average WTA compensation was NPR 1268.67 (USD 9.76)/Kattha/year, with 2.64 Kattha land available for AF. The factors, including socioeconomic characters and attitudes toward the environmental situation and forests, significantly influenced WTA values and provided potential target factors to achieve maximum AF land within a lower budget.

Background: Anxiety is one of the most frequent disorders during the perinatal stage that is associated with adverse health effects in women and their babies. In spite of this, preventive interventions during this stage are scarce. A long-distance intervention carried out during pregnancy can be an effective and accessible resource to help improve women’s emotional state. The objective of this study is to present and assess the effectiveness of a telepsychology cognitive–behavioral preventive intervention during pregnancy to manage anxiety. Methods: A random clinical trial will be carried out among pregnant women in Spain. The psychological intervention will take place via videoconference in seven weekly sessions, lasting one hour each, with groups of 6–8 pregnant women. Study outcomes will be collected via online questionnaires at five points in time: pre-intervention (baseline: t0), post-intervention (baseline: t1), follow-up at 1 month (t2), follow-up at 3 months (t3) and follow-up at 6 months (t4). The control group will receive usual pregnancy care (attendance at pregnancy follow-up consultations and information and answers to frequently asked questions provided by the midwife). Our primary hypothesis is that the intervention will decrease the frequency of women who present anxious symptomatology during pregnancy. The second objective is to analyze the effectiveness of this intervention to prevent depressive symptomatology during pregnancy, as well as postpartum anxiety and depressive symptomatology. The primary outcome measure is the difference in the mean anxiety score between the intervention and control groups assessed by the Edinburgh Depression Scale-Anxiety Subscale (EDS-3A), the State–Trait Anxiety Inventory (STAI) and Generalized Anxiety Disorder Screener (GAD-7) at the end of the intervention and at 1, 3 and 6 months postpartum. Generalized anxiety disorder (GAD) will be evaluated with the SCID clinical interview at the same time points. The secondary outcome will be determined by using the EPDS at the same time points. Conclusions: The results will determine whether a cognitive behavioral therapy applied via videoconference is well accepted by pregnant women, and if it is effective in preventing anxiety and emotional symptoms during the perinatal stage. If this intervention is an effective and useful resource among pregnant women, it can be implemented as a tool in Spanish healthcare. Full article

Background/Objectives: Pegvaliase, a subcutaneous therapy to treat phenylketonuria (PKU), has allowed these patients to maintain adequate phenylalanine (Phe) blood values without following a Phe-controlled diet; this brings up the challenge of promoting healthy eating while moving away from prescription diets. In our center, every patient treated with Pegvaliase undergoes routine nutritional counseling aimed at promoting adherence to the Mediterranean diet (MedDiet) during regular inpatient visits. This study aims to assess adherence to MedDiet and the adequacy of the diets of patients treated with Pegvaliase regarding micro- and macronutrients. Methods: Seven patients on chronic therapy with Pegvaliase underwent a dietetic evaluation to assess the composition of their diets in terms of micro- and macronutrients; they were also administered the Mediterranean Diet Score (MDS) questionnaire. Subcategories from MDS were extracted to evaluate the consumption of foods typically included (vegetables, olive oil, etc.) and typically excluded (red meat, etc.) in the MedDiet. To assess the adequacy of the diet, nutrient and energy levels were compared with guidelines for the Italian population. Results: MedDiet adherence in our sample was comparable to the general population; in terms of macronutrients, good adherence to the recommendations was observed, with every one of them met except for excessive simple sugar consumption. Micronutrient dietary intake was inadequate for zinc, iron, selenium, folate, thiamine, and riboflavin. Conclusions: While more work is necessary to help patients treated with Pegvaliase to progress toward healthy eating, our study suggests that nutritional counseling routinely performed during inpatient visits, typically twice a year, effectively promotes healthier eating habits than those observed in the general population.
