Virtual Reality as an Adjunct to Traditional Patient Counseling in Patients With Newly Diagnosed Localized Prostate Cancer

ObjectivesTo determine the utility of a virtual reality (VR) model constructed using patient-derived clinical imaging to improve patient understanding of localized prostate cancer (PCa) diagnosis and surgical plan. MethodsPatients undergoing robotic radical prostatectomy were selected and demographic data recorded. Patients completed a questionnaire to assess baseline knowledge of their diagnosis after consultation and shared-decision making with their surgeon. A trained non-clinical staff member then guided the patient through a VR experience to view patient-specific anatomy in a 3-dimensional space. Patients then completed the same questionnaire, followed by an additional post-VR questionnaire evaluating patient satisfaction. Questions 1-7 (patient understanding of prostate cancer and treatment plan) and 11-17 (patient opinion of VR) used a standard Likert scale and Questions 8-10 were multiple choice with 1 correct answer. ResultsIn total, 15 patients were included with an average age of 64.1 years. 6 of 7 questions showed an improvement after VR (p<0.001). The percentage of correct responses on Questions 8-10 were higher after VR but not statistically significant (p>0.13). Mean responses range from 4.3 to 4.8 (Likert scale, 1 through 5) for the post-VR questionnaire, with a mean total of 31.9 out of 35. ConclusionThis small preliminary investigation of a novel technology to improve the patient experience showed potential as an adjunct to traditional patient counseling. However, due the small sample size and study design, further research is needed to determine the value VR adds to prostate cancer surgical counselling.

A synthetic vulnerable population dataset for fine scale geographical equity analysis and urban planning

Assessing the social and economic vulnerability of populations within a given area is essential for conducting environmental equity evaluations and devising effective public policies to mitigate disparities. However, prevailing indicators used to measure socio-economic vulnerability exhibit several shortcomings. Primarily relying on factor analysis, these indicators face challenges in terms of comparability over time, lack of standardized scales, and inherent limitations associated with composite indicators. To address these shortcomings, we propose a novel approach that estimates the number of potentially vulnerable individuals by constructing a synthetic population. Our methodology, developed using open tools and datasets, offers a scalable solution applicable to the entire Canadian context. The resulting percentage of potentially vulnerable populations demonstrates strong correlations with traditional vulnerability indicators commonly used in Canada, while overcoming their inherent limitations. The generated dataset holds significant potential and serves as a valuable resource for both researchers and governmental organizations. It provides a robust foundation for conducting equity analyses, assessments, and policy evaluations, thereby facilitating evidence-based decision-making processes aimed at promoting social and economic inclusivity.

C-reactive protein in anhedonia among patients with major depressive disorder and its relation to suicidal ideation

BackgroundThere is evidence that major depressive disorder (MDD) with its cardinal symptoms, anhedonia and suicide, are linked with raised inflammatory markers like C-reactive protein (CRP). This case–control study investigated the correlation between high sensitive CRP (Hs-CRP), anhedonia, suicidal ideation, and depression severity in MDD patients.MethodsForty-one MDD patients and 47 healthy controls were recruited. MDD diagnosis was confirmed using DSM-5 criteria. Depression severity, anhedonia, and suicidal ideation were assessed using standardized scales. Serum Hs-CRP levels were measured as an inflammatory marker.ResultsMDD cases had significantly greater Hs-CRP levels compared to controls. Additionally, Hs-CRP levels were positively correlated with both anhedonia and suicidal ideation in MDD cases. Depression severity was significantly linked with both anhedonia and suicidal ideation.ConclusionThis study suggests a link between inflammation, anhedonia, suicidal ideation, and depression severity in MDD patients. Additional research is necessary to find out the principal mechanisms.

Psychological Study on the Influence of Physical Exercise on College Students’ Anxiety

This study aims to explore the impact of physical exercise on the anxiety level of college students. We collected physical exercise data and anxiety self-assessment results from college students of different grades, genders, and ages from multiple universities in Guangdong Province through a questionnaire survey. The study used standardized scales to evaluate participants’ physical exercise types, frequencies, intensities, and anxiety levels. The data analysis results showed that there is a significant negative correlation between college students’ physical exercise and anxiety level, that is, the more frequent and intense the physical exercise, the lower the anxiety level. In addition, there are differences in the effect of different types of physical exercises on anxiety relief, with aerobic exercises such as running and swimming showing more significant anxiety-relieving effects. The research results provide valuable references for psychological health education and anxiety intervention strategies in universities and suggest promoting physical exercise to effectively alleviate college students’ anxiety.

Neurophysiological markers of motor compensatory mechanisms in early Parkinson's disease.

Compensatory mechanisms in Parkinson's disease are defined as the changes that the brain uses to adapt to neurodegeneration and progressive dopamine reduction. Motor compensation in early Parkinson's disease could, in part, be responsible for a unilateral onset of clinical motor signs despite the presence of bilateral nigrostriatal degeneration. Although several mechanisms have been proposed for compensatory adaptations in Parkinson's disease, the underlying pathophysiology is unclear. Here, we investigate motor compensation in Parkinson's disease by investigating the relationship between clinical signs, dopamine transporter imaging data and neurophysiological measures of the primary motor cortex (M1), using transcranial magnetic stimulation in presymptomatic and symptomatic hemispheres of patients. In this cross-sectional, multicentre study, we screened 82 individuals with Parkinson's disease. Patients were evaluated clinically in their medication OFF state using standardized scales. Sixteen Parkinson's disease patients with bilateral dopamine transporter deficit in the putamina but unilateral symptoms were included. Twenty-eight sex- and age-matched healthy controls were also investigated. In all participants, we tested cortical excitability using single- and paired-pulse techniques, interhemispheric inhibition and cortical plasticity with paired associative stimulation. Data were analysed with ANOVAs, multiple linear regression and logistic regression models. Individual coefficients of motor compensation were defined in patients based on clinical and imaging data, i.e. the motor compensation coefficient. The motor compensation coefficient includes an asymmetry score to balance motor and dopamine transporter data between the two hemispheres, in addition to a hemispheric ratio accounting for the relative mismatch between the magnitude of motor signs and dopaminergic deficit. In patients, corticospinal excitability and plasticity were higher in the presymptomatic compared with the symptomatic M1. Also, interhemispheric inhibition from the presymptomatic to the symptomatic M1 was reduced. Lower putamen binding was associated with higher plasticity and reduced interhemispheric inhibition in the presymptomatic hemisphere. The motor compensation coefficient distinguished the presymptomatic from the symptomatic hemisphere. Finally, in the presymptomatic hemisphere, a higher motor compensation coefficient was associated with lower corticospinal excitability and interhemispheric inhibition and with higher plasticity. In conclusion, the present study suggests that motor compensation involves M1-striatal networks and intercortical connections becoming more effective with progressive loss of dopaminergic terminals in the putamen. The balance between these motor networks seems to be driven by cortical plasticity.

Optimized seismic hazard and structural vulnerability model considering macroseismic intensity measures

Macroseismic intensity measures are fundamental quantitative indicators for evaluating the vulnerability and resilience of regional building clusters. The vulnerability model of building portfolios established can provide a noteworthy reference for the development of large-scale regional earthquake risk distributions. However, there are differences in the quantitative scales of the macroseismic intensity standards used in multiple regions. The positive effects of instrument intensity and probabilistic seismic hazard theory on the vulnerability assessment of regional buildings are rarely considered, resulting in significant differences in their assessment results. This paper comprehensively considers the impact of instrument intensity and seismic hazard models on traditional macroseismic intensity. An updated macroseismic intensity measure (UCMS-20) is proposed for evaluating regional buildings, which is combined with the latest version of China's seismic intensity standards. The actual seismic damage sample dataset (31,649 buildings) of four types of building clusters in three typical earthquakes in China (Wenchuan 2008, Yushu 2010, and Jiuzhaigou 2017) has been expanded and updated. Using the UCMS-20, the European Macroseismic Scale (EMS-98), the Modified Mercalli intensity (MMI), and the Medvedev, Sponheuer, and Karnik Scale (MSK-64), vulnerability assessments are conducted on the extended empirical structural seismic damage dataset, and an empirical disaster matrix model considering updating damage states is established. A nonlinear vulnerability prediction model considering updated macrointensity measures is proposed, and the optimized model is validated and compared against the developed multiscale empirical structure dataset. The multiscale vulnerability index calculation model is improved, and novel optimization curves, point clouds, and matrix probability risk models are established, considering the expansion of empirical structural vulnerability databases.

The impact of public art education on college students' mental health literacy.

This study aims to explore the impact of public art education on the mental health literacy of College Students. Conducted over a four-month period, the intervention involved freshmen from a Chinese college, comparing 1,334 students in the experimental group with 1,139 in the control group. Data were collected through a self-developed questionnaire and a standardized mental health literacy scale before and after the intervention. Results showed that the experimental group's overall mental health literacy score significantly increased from 64.051 pre-intervention to 79.260 post-intervention, while the control group showed no significant changes during the same period. The experimental group demonstrated significant improvements in their ability to identify psychological disorders, belief in receiving professional help, attitudes towards seeking appropriate help, and knowledge in seeking mental health information. Furthermore, the frequency of classroom interaction was positively correlated with improvements in mental health literacy (regression coefficient = 2.261***), highlighting the critical role of active participation in public art education settings. This study underscores the importance and effectiveness of implementing public art education in higher education and provides empirical support for future educational policies and practices.

Impact of Foot Reflexology Versus Simple Massage on Vital Signs, Anxiety, and Pain During Blood Transfusion Among Children With Thalassemia.

Introduction Children with thalassemia often require repeated invasive treatments and frequent hospitalizations, resulting in pain, anxiety, and altered vital signs. Implementing non-invasive, non-pharmacological, and inexpensive complementary practices can benefit both the child and their family. Aim This study aimed to evaluate the impact of foot reflexology versus simple massage on vital signs, anxiety,and pain induced by blood transfusions in children with thalassemia. Materials and methods An experimental study was conducted on 60 children with thalassemia; children aged 2-13 years were selected by systematic random sampling.The participants were separated into two groups: 30 children received foot reflexologyand 30 children received a simple massage. Data were collected using a self-structured demographic profile, vital signs record sheet, standard Observational Scale of Behavioral Distress-Revised (OSBD-R) scale,and visual analog scale (VAS). Paired and unpaired t-tests were used to evaluate the effects of the interventions. The chi-square test was utilized to evaluate the relationship between demographic and dependent variables. Result Foot reflexology showed a significant difference (P < 0.05) in systolic and diastolic blood pressure and a highly significant difference (P < 0.0001) in anxiety and pain. The simple massage group showed a significant effect on temperature, anxiety, and pain. Both groups demonstrated a significant impact (P < 0.05) on systolic blood pressure and pain after the intervention. Conclusion Most children were diagnosed with thalassemia during infancy, had a history of both parent's thalassemia minor, and were Rh+ve. Foot reflexology was more effective in reducing anxiety and pain than simple massage. Additionally, foot reflexology had a significant effect on systolic and diastolic blood pressure, while simple massage significantly affected temperature in children with thalassemia.

Reliability and validity of the ratings of perceived stability scale as a measure of balance exercise intensity in persons with multiple sclerosis

Purpose The study aimed to determine the test-retest reliability and concurrent validity of the Ratings of Perceived Stability (RPS) scale as a measure of balance exercise intensity in persons with multiple sclerosis (MS). Methods Twenty participants with MS (mean age: 58.1 ± 15.29; 60% female) performed 14 balance tasks on two separate occasions wearing body-worn inertial sensors and rated their perceived stability for each task. Sensor data included sway velocity and angle, gait speed, turn velocity, and lean angle. Intraclass correlation coefficients (ICC) and Spearman rank correlations (r s) were employed to assess reliability and validity, respectively. Results The RPS showed good to excellent test-retest reliability (ICC> 0.75) on 12 out of the 14 tasks. The stability ratings revealed moderate relationships with postural sway outcomes in static balance tasks (r s: 0.49 to 0.77) and weak to moderate associations with gait speed (r s: −0.69 to −0.14). Ratings of stability were also strongly related to turn velocity (r s= −0.77) and moderately related to lean angle (r s= 0.58). Conclusions The RPS scale offers a promising clinical tool to measure balance exercise intensity for persons with MS. This standardized scale allows for tailored balance training with a novel means for exercise monitoring and progression in this population.

The role of knowledge and attitudes toward older adults in understanding nursing students’ inclination to work with them: A cross-sectional study

ABSTRACT Singapore’s population is aging. Currently, 15% of Singapore’s population is 65 years and above. Low birth rates and high life expectancy have fueled a high demand for geriatric care in Singapore. This research explores the role of knowledge that nursing students have about aging, their attitudes toward older adults, and their inclination to pursue careers in geriatric nursing. This cross-sectional study administered standardized scales to understand 347 nursing students’ knowledge (Palmore Facts on Aging Quiz), attitudes (Kogan’s Attitudes toward Older People) and inclinations (Nolan’s Intent to Work with Older People). Results showed that Singapore nursing students have a moderate level of knowledge about aging and showed a strong willingness to work with older adults. Younger students displayed higher knowledge, better attitudes, and a greater inclination to work with older adults than older students. Furthermore, local students exhibited higher knowledge, more positive attitudes, and greater interest in working with older adults than their international counterparts. This study, conducted during the COVID-19 pandemic, revealed valuable insights into our nursing students’ perspectives on aging. Nursing students displayed a moderate understanding of aging, a positive attitude toward older adults and a strong desire to serve them, suggesting a potential future workforce ready to fulfill the demands of Singapore’s aging population. This insight is valuable for educators, guiding them to bridge knowledge gaps and foster open conversations about aging.

A Comparison of Telesimulation Using the Virtual Resus Room and In Situ Simulation in Pediatric Emergency Medicine.

During the COVID-19 pandemic, there was a marked shift toward telesimulation in medical education. Limited studies exist comparing the effectiveness of online and offline simulation education. The goals of this study are to evaluate active learners' perceived effectiveness of telesimulation versus in situ simulation and to identify potential shortcomings of existing online teaching platforms. Through participant evaluations after a simulation, we compared telesimulation using the Virtual Resus Room (VRR) to in situ simulation in the domains of (1) self-efficacy, (2) fidelity, (3) educational value, and (4) teaching quality. Study subjects included medical and pharmacy residents and medical students completing their pediatric emergency medicine rotation at two children's hospitals as well as nurses, nurse practitioners, and physician assistants who were recently hired and orienting to their new roles in the emergency department. Learners used a modified Michigan Standard Simulation Experience Scale to evaluate either a telesimulation or in situ simulation case. Survey responses were compared using Wilcoxon rank sum tests with Bonferroni correction for multiple comparisons. In overall assessment, in situ simulation was rated higher than telesimulation. There were significant differences noted related to perceived realism, utility in training device-related skills, and utility in training team-building skills. All P values were less than 0.0036. There were no significant differences between simulation types in perception of physical examination fidelity, instructor adequacy, or self-efficacy. Telesimulation using the VRR is comparable to in situ simulation in learners' perception of improvement in self-efficacy and of teaching quality for pediatric emergency medicine topics. However, participants felt less able to practice tactile and communication skills virtually. Further innovation is needed to improve learners' experience with fidelity and educational value.

Coordination and Referral Platforms for Children Aged 7 and Under with Suspected Neurodevelopmental Outcome: What Data for Research on Care and Developmental Trajectories?

At the core of the child's medical, social, and educational pathway, coordination and referral platforms (CRPs) for neurodevelopmental disorders (NDDs) have been gradually deployed in France since 2018 and support the early detection of NDDs in children. The 112 nationwide CRPs do not benefit from a common electronic health record system. Our aim was to propose an HER model for CRP to enable real-life data reuse, optimize care pathway management and conduct pre-screening for research. CRP data were collected (n=34) into an application enriched by a NLP tool extracting standardized scales for NDDs assessments from medical and paramedical professionals. NLP tool evaluation presented a precision of 86.4% and recall of 90.5%. CRP support was provided to 195 children included between 1 September 2022 and 31 August 2023, aged 4 years, with a sex ratio of 2.8, with delays reported in language (75%) and concerned by global developmental delays (16%). Children's ND phenotype and care pathway description could be automated by a harmonized and structured EHR. While many clinical situations are at an impasse, real-life data-driven evidence is particularly relevant in the context of NDDs, where early intervention plays such a key role in children's development and prognosis. A harmonized and enriched CRP database could benefit both individual and public health levels with pathway monitoring, intervention proposals and research pre-screenings.

Adoptees' experiences of using direct-to-consumer genetic testing and determinants of this use: A mixed study in Quebec.

Adoptees' use of direct-to-consumer genetic testing (DTC-GT) is known to raise both ethical and emotional issues, and it can also challenge their identity. The objective of the present study was to describe the experiences of DTC-GT use among adoptees living in Quebec and to better understand the benefits and disadvantages of use. We adopted a mixed method approach whereby a questionnaire comprising standardized scales was administered to 143 adoptees who had used genetic testing and 40 adoptees who had not. Semi-structured interviews were performed with five respondents from the DTC-GT use group. The quantitative and qualitative data were analyzed and integrated together using the Pillar Integration Process. The results highlighted familial reunion as the primary motivation for the use of DTC-GT among responding adoptees. Reported challenges included needing help with results interpretation, as well as the need for autonomy in the ownership of the results. Participants describe not being particularly concerned by potential ethical issues, describing the benefits of the tests as more important than possible disadvantages. Overall, participants had a good experience of using DTC-GT, and users were less anxious. Various factors associated with the use and experience of use were highlighted (age, psychological distress, community membership, etc.). The results from this study provide much-needed information about adoptees' needs regarding DTC-GT, highlight key risk factors, and introduces best practice recommendations so that adoptees are properly informed and supported when pursuing DTC-GT.

Ethical work climate and organizational citizenship behavior in collectivist culture: does power distance matter?

PurposeDrawing from social exchange theory and a collectivist cultural framework, this study explores the relationship between ethical work climate and organizational citizenship behavior, considering power distance as a potential moderator.Design/methodology/approachThe study used standard scales to obtain data from 244 employees working in various private companies in India. Structural equation modeling was adopted to test the hypotheses using Analysis of Moment Structures (AMOS).FindingsThe study results show a significant relationship between ethical climate and organizational citizenship behavior. Ethical work climate influences power distance negatively. However, the results also show that power distance does not serve as a moderator between ethical work climate and organizational citizenship behavior.Practical implicationsCorporate leaders often expect employees to demonstrate organizational citizenship behavior, which is aimed at advancing the organization’s interests and outcomes. This study underscores the necessity for expanding the organizational vision to enhance the ethical work climate. Such an initiative not only promotes improved organizational citizenship behavior but also helps to reduce employees' perceptions of power distance within the organization.Originality/valueAmid extensive literature rooted in individualistic cultures, our study explores the relationship between ethical work climate and organizational citizenship behavior within a collectivist context. This research uniquely introduces the moderating role of power distance, offering new and distinct insights into this dynamic.

The role of nurses' adherence to clinical safety guidelines in linking nurse practice environment to missed nursing care.

While the nurse practice environment's vital role in shaping patient care outcomes is well established, the precise mechanisms through which it influences missed nursing care remain unexplored. Hence, this study examined the mediating role of adherence to clinical safety guidelines in the relationship between the nurse practice environment and missed nursing care. This descriptive, cross-sectional study involved 1237 nurses from 11 governorates in the Sultanate of Oman. Data were collected using three standardized scales: the Patient Safety Adherence Scale, the Practice Environment Scale of the Nursing Work Index, and the Missed Nursing Care Scale. A favorable nurse practice environment was associated with higher adherence to clinical safety guidelines (β = 2.492, p < 0.001) and a lower frequency of missed nursing care (β = -0.2919, p = 0.015). Adherence to clinical safety guidelines partially mediated the relationship between the nurse practice environment and missed nursing care (β = -0.055, p < 0.001). Enhancing the nurse practice environment plays a crucial role in improving nurses' adherence to clinical safety guidelines, which in turn reduces compromised nursing care. Healthcare administrators and policymakers should prioritize improving working conditions to enhance nurses' adherence to clinical safety guidelines, thereby minimizing the occurrence of missed care and improving overall patient outcomes.

Chemical and enzymatic hydrolysis of alginate: a review

Abstract Alginate is a brown seaweed-based linear polysaccharide of D – mannuronic acid and L – guluronic acid residues. Hydrolysis products of the polysaccharide, specifically oligosaccharides, have been receiving increasing interest, due to their significant bioactivity and potential utilisation routes. The bioactivity of alginate oligosaccharides is closely linked to structural characteristics, namely: molecular weight, degree of polymerisation, and ratio of the monomers (the M/G ratio). Hence, potential applications (such as utilisation as a biostimulant fertilizer) depend on these parameters. This review focuses on recent advances in producing alginate oligosaccharides using chemical or enzymatic methods. The literature survey includes utilisation of these methods at both laboratory and industrial scale. For the chemical methods, we assessed the standard laboratory scale procedures of alginate oligosaccharide production, the potential of scaling up to an industrial level, and the subsequent challenges. For the enzymatic route, we provide an overview of alginate lyases and the application perspectives of enzymatic hydrolysis of alginate.

Effect of low-intensity pulsed ultrasound on postoperative rehabilitation of rotator cuff tears: Protocol for a systematic review and meta-analysis.

Rotator cuff tears are a common shoulder injury that significantly impacts patients' daily lives and work abilities. Although surgical treatment methods for rotator cuff tears have been continuously improved with advances in medical technology, postoperative rehabilitation remains challenging. Therefore, finding effective rehabilitation treatments is crucial for improving patient prognosis and enhancing quality of life. This study will aim to systematically evaluate the impact of low-intensity pulsed ultrasound (LIPUS) on postoperative rehabilitation of rotator cuff tears, comprehensively assessing the efficacy and safety of LIPUS in postoperative recovery. This protocol will search multiple databases including PubMed/MEDLINE, Embase, Cochrane Library, CNKI, Scopus, and Web of Science to identify randomized controlled trials related to LIPUS for postoperative rehabilitation of rotator cuff tears. The search will encompass literature published from the inception of the databases up to April 2024. Methodological quality assessment and data extraction will be conducted using the Cochrane Handbook for Systematic Reviews of Interventions and PRISMA guidelines. Meta-analysis will be performed on appropriate studies using either random-effects or fixed-effects models, and subgroup analyses will be conducted to explore potential heterogeneity. Studies meeting the inclusion criteria will be included in the analysis. All analyses will be performed using Stata version 16.0. The incidence of rotator cuff tear rates will be assessed by imaging techniques such as MRI or ultrasound. Pain intensity will be scored using standardized pain assessment scales, such as the Visual Analog Scale (VAS). Improved range of motion (ROM) in shoulder flexion, abduction, and rotation. Functional outcomes will be evaluated using effective measures such as Constant-Murley scores (CMS) and shoulder joint scores by American Shoulder and Elbow Surgeons (ASES). Adverse events associated with LIPUS therapy, including skin irritation, increased pain, or any other complications. Subgroup analysis will also be carried out if possible. Following the meta-analysis, we will assess the overall effect of LIPUS on postoperative rehabilitation of rotator cuff tears, and further explore its impact on aspects such as pain relief, functional improvement, and postoperative complications. It is anticipated that this study will provide comprehensive evidence regarding the role of LIPUS in postoperative rehabilitation of rotator cuff tears, guiding clinical practice and future research. The resultant manuscript will be submitted for publication in a peer-reviewed journal. CRD42024530798.

Exploring socioeconomic status, lifestyle factors, and cardiometabolic disease outcomes in the United States: insights from a population-based cross-sectional study

BackgroundCardiometabolic diseases are a major global health concern. This study aims to identify areas for targeted interventions and investigate the impact of socioeconomic status and lifestyle as a potential mediator in the context of the US.MethodsOur study analyzed data from the Health Information National Trends Survey 5, a nationwide survey by the National Cancer Institute. Using standardized scales and questions, we examined cardiometabolic disease outcomes, lifestyle factors, and socioeconomic status of non-institutionalized civilians aged 18 + in the US. We analyzed the data using structural equation modelling.ResultsOur findings show that socioeconomic status and lifestyle significantly predict cardiometabolic disease outcomes. However, our analysis did not support lifestyle as the primary mediating factor in the association between socioeconomic status and cardiometabolic diseases, suggesting that other factors may significantly influence this relationship.ConclusionsCardiometabolic diseases require lifestyle and structural interventions addressing socioeconomic factors. Policymakers must consider multifaceted factors to prevent, detect, and manage these diseases effectively and equitably.
