Evaluation of YouTube Videos as a Source of Information about Dementia Care

Aim: Digital platforms such as YouTube are popular sources of health-related information. Although there are studies evaluating the quality of different online medical content, studies focusing on the quality of dementia-related content are limited. This study aimed to investigate the quality of YouTube videos related to dementia patient care. Material and Methods: Using the term "Dementia care" on the YouTube platform, 100 English videos that met the inclusion criteria were identified and analyzed. In addition to video popularity measurements, to evaluate content quality, the global quality scale (GQS), modified DISCERN scale, Journal of the American Medical Association (JAMA) quality scale, and the patient education materials assessment tool for audio/visual materials (PEMAT-A/V) are used. Results: It was observed that most of the videos were uploaded by non-academic health institutions (36%) and health professionals (23%). When the content of the videos was evaluated, it was determined that general care strategies were the most common content with 52%. Scores indicating high levels of reliability and accuracy were determined on all applied content quality scales. Videos sourced from academic healthcare institutions were found to have the highest scores on content quality scales. In correlation analyses, video metrics such as duration, view ratio, number of comments, and video power index values were positively correlated with content quality scores. Conclusion: Videos about dementia patient care on YouTube generally exhibit high popularity and content quality. Individuals seeking information about dementia care on online platforms should be directed to videos uploaded by healthcare institutions.

COVID-19 Impact on Substance Use (Tobacco, Alcohol, Cannabis) and Stress in Medical Students

The COVID-19 pandemic has led to unprecedented challenges globally, impacting various aspects of daily life, including education. This study examines the effects of the pandemic on stress levels and substance use among Italian medical students. Two independent surveys were conducted: 388 medical students were interviewed before the epidemic, and 222 medical students a year after the COVID-19 epidemic began. Results revealed significant changes in stress levels, with a reduction in mild stress and an increase in severe stress during the post-pandemic period, rising from 23% (95% CI: 19%-28%) to 46% (95% CI: 39%-52%). While tobacco smoking prevalence remained stable (25% vs 27%), the proportion of students exhibiting high levels of nicotine dependence increased (3.64%) compared to the period before the pandemic (1.80%). Alcohol consumption rates remained consistent (66%), with no significant differences in the distribution of risky alcohol consumption between the two periods (<em>p</em> = 0.535). Surprisingly, there was a significant decrease in cannabis use post-pandemic (16% vs 6%), though problematic use among users persisted (49% vs 46%). Multivariable analysis confirmed associations between stress and tobacco smoking (AdjOR = 1.98, 95% CI: 1.11-3.53; <em>p</em> = 0.020), as well as alcohol consumption (AdjOR = 1.71, 95% CI: 1.01-2.89; <em>p</em> = 0.047). Furthermore, male students were more likely to engage in alcohol (AdjOR = 2.16, 95% CI: 1.47-3.19; <em>p</em> < 0.001) and cannabis use (AdjOR = 1.79, 95% CI: 1.07-3.00; <em>p</em> = 0.027). The study highlighted the complex interplay between stress and substance use among medical students, underscoring the importance of targeted interventions to address stress-related substance use and support the well-being of medical students, particularly in the context of the COVID-19 pandemic. Further research should explore longitudinal trends and the effectiveness of interventions in mitigating stress-related substance use among this vulnerable population.

Ten golden rules for restoration to secure resilient and just seagrass social‐ecological systems

Societal Impact StatementSeagrass meadows are a globally important habitat subject to significant loss. As efforts to restore these sensitive habitats are hampered by their high cost and low levels of reliability, rigorous guidance is required to improve effectiveness and ensure they are cost‐effective. Here, we define 10 golden rules for how we can undertake seagrass restoration. We do this by considering that for seagrass restoration to be successful, it needs to take place with people and not against people. The framework we present aims to direct efforts for seagrass restoration that are holistic and achieve broad goals for people, biodiversity and the planet.SummaryThe world has lost a significant proportion of its seagrass, and although glimmers of hope for its recovery exist, losses and degradations continue. First and foremost, evidence highlights the need to put the world on a global pathway to seagrass net gain. Achieving this outcome requires that conservation of what remains is a priority, but reaching net gain requires seagrass coverage to increase at rates unlikely to be achieved naturally; large‐scale active restoration is required to fill this gap. Novel finance mechanisms aligned to the climate emergency and biodiversity crises are increasingly leading to larger scale restoration projects. However, no clear framework exists for developing or prioritising approaches. With seagrass restoration expensive and unreliable, rigorous guidance is required to improve effectiveness and ensure it is cost‐effective. Building on evidence from terrestrial and marine sources, here, we apply the ‘10 golden rules’ concept, first outlined for reforestation and later applied to coral reefs, to seagrass restoration. In doing so, we follow international standards for ecological restoration and view seagrass restoration in a broad context, whereby regeneration can be achieved either by planting or by enhancing and facilitating natural recovery. These rules somewhat differ from those on reforestation and coral reef restoration, principally due to the relative immaturity of seagrass restoration science. These 10 golden rules for seagrass restoration are placed within a coupled social‐ecological systems context, and we present a framework for conservation more broadly, to achieve multiple goals pertaining to people, biodiversity and the planet.

The Chinese Mandarin COMHON Index and Braden Scale to assess pressure injury risk in intensive care: An inter-rater reliability and convergent validity study

BackgroundThe COMHON Index is an intensive-care-specific pressure injury risk assessment tool, which has demonstrated promising psychometric properties. It has been translated into Chinese Mandarin but requires inter-rater reliability testing and comparison to the standard care instrument (Braden Scale) before clinical use. ObjectivesThis study aimed to test and compare the inter-rater reliability and convergent validity of the Chinese Mandarin versions of the COMHON Index and Braden Scale. MethodsThe study was conducted in a Chinese comprehensive intensive care unit. Based on a sample size calculation, five registered nurse raters with at least 6-months experience independently conducted risk assessments for 20 adult patients using both the COMHON Index and Braden Scale. Intraclass correlations (ICC) for inter-rater reliability, standard errors of measurement (SEM), and minimally detectable change (MDC) were calculated. Convergent validity was assessed using Pearson Product Moment Correlation for sum scores and Spearman's rho for subscales. ResultsInter-rater reliability of COMHON Index and Braden Scale sum scores was very high (ICC [1,1] = 0.973; [95% confidence interval 0.949–0.988]; SEM 0.54; MDC 1.50) and high (ICC [1,1] = 0.891; [95% confidence interval 0.793-0.951]; SEM 0.93; MDC 2.57), respectively. All COMHON-Index subscales demonstrated ICC values >0.6, whereas two Braden Scale subscales (Mobility, Activity) were below this threshold. Instrument sum scores were strongly correlated (Pearson's r = −0.76 [r2 = 0.58]; p < 0.001), as were three subscale item pairs (mobility rs= −0.56 [r2 = 0.32]; nutrition rs= −0.63 [r2 = 0.39]; level of consciousness/sensory perception rs= −0.67 [r2 = 0.45] p < 0.001). ConclusionBoth the COMHON Index and Braden Scale demonstrated high levels of inter-rater reliability and measured similar constructs. However, the COMHON Index demonstrated superior inter-rater reliability and the results suggest that it better detects changes in patient condition and subsequently pressure injury risk. Further testing is recommended.

Reliability and separation index analysis of mathematics questions integrated with the cultural architecture framework using the Rasch model

This research uses Rasch model analysis to identify the reliability and separation index of an integrated mathematics test instrument with a cultural architecture structure in measuring students' mathematical thinking abilities. The study involved 357 students from six eighth-grade public junior high schools in Bima. The selection of schools was based on average school exam scores and considered the effectiveness of the learning process that used cultural settings to explore mathematical content. Data analysis was conducted using Microsoft Excel to calculate the content validity of Aiken's index with four experts and the jMetrik software to measure reliability and the separation index. The research results indicate that the mathematics test instrument passed validation by mathematics experts and measurements with a valid content validity level. Rasch model calibration shows a very high level of instrument reliability. Separation analysis on the logit scale indicates the instrument's ability to differentiate students with different ability levels with good homogeneity in the distribution of test items and individual abilities. Scale quality statistics show good item response variability, low error rates and a high separation index. This study has limitations because it focuses solely on multiple-choice questions. Similar research must be conducted using other types of questions (such as those used in PISA, namely open- constructed and closed-constructed questions) and integrating other mathematical materials within relevant cultural architectural structures.

Development of Body Safety Module Among Elementary School Students: Perception of Effectiveness on SDGS

Objective: Sexual education for children is crucial as it aids in their understanding and appreciation of their bodies. This research aims to develop a Body Safety Module as a teaching tool for primary school students. The modules were analyzed to determine perception of usability as well as their effectiveness. Methods: This study focuses on design and development research, adopting the five phases in the ADDIE model for the module development process. To evaluate the module’s effectiveness, 205 respondents were randomly chosen to complete a questionnaire. Furthermore, an additional 71 pupils participated in pre- and post-effectiveness tests. This study examined three specific aspects of validity: content validity, questionnaire validity, and the effectiveness of pre and post-test. Results and conclusion: The module received extensive professional review and agreement, showing a 93.73% agreement on the validity of the content. Meanwhile, the test of the effectiveness of the module using questionnaires reflected a validity rate of 93.3%. The questionnaire also demonstrated a high level of reliability (α = 0.766). Data analysis was performed using inferential statistics (T-test) and descriptive statistics (mean and standard deviation). When assessing student perceptions of the module, a moderate level of agreement was found across various aspects: design (M 2.67, SD 0.51), satisfaction (M 2.36, SD 0.67), and usability (M 2.69, SP 0.52). There was a significant difference in mean scores between the control and treatment groups in post-test results. In this aspect, the Body Safety Module proved more effective than traditional textbooks for students. As a result, this module is an appropriate teaching tool for elementary school students. Research Implications: This module serves a broader purpose than merely a teaching tool; it is suitable for children aged from 7 to 12 years old. This early sexual education module delivers crucial knowledge and awareness, empowering children to protect their precious bodies and recognize sexual harassment instances. Gender equality is closely linked to the prevention of sexual harassment and abuse. The Body Safety Module addresses these issues by fostering awareness among children, regardless of gender, about their rights and boundaries.

Effect of a 12-Week Strength Training Program on Muscle Strength Measures of Institutionalized Older Adults-A Pilot Study.

Institutionalized older adults are characterized by high levels of dependence and low levels of physical activity compared to those living in the community. This combination of factors leads to an increased risk of loss of muscle mass. Sarcopenia can be countered through strength training. The aim of the present study was to evaluate the effect of a strength training program on the physical fitness of institutionalized older adults. This study included a sample of 31 institutionalized older adults (20 females, 11 males) aged between 65 and 96 years (M = 81.64, SD = 8.67). Participants reported an average institutionalization duration of 2.43 years (SD = 2.20), ranging from half a year to ten years. A 12-week strength training program was implemented, with sessions held twice a week. Strength fitness was assessed through the following parameters: handgrip strength, upper limb muscular endurance, lower limb muscular endurance, agility and balance, body mass index, and waist circumference. The results demonstrated that a 12-week strength training program improved physical fitness in terms of lower limb muscular endurance, upper limb muscular endurance, agility, and dynamic balance (p < 0.05).

Study of a Narrow Fabric-Based E-Textile System-From Research to Field Tests.

Electronic textiles (e-textiles) are a branch of wearable technology based on integrating smart systems into textile materials creating different possibilities, transforming industries, and improving individuals' quality of life. E-textiles hold vast potential, particularly for use in personal protective equipment (PPE) by embedding sensors and smart technologies into garments, thus significantly enhancing safety and performance. Although this branch of research has been active for several decades now, only a few products have made it to the market. Achieving durability, reliability, user acceptance, sustainability, and integration into current manufacturing processes remains challenging. High levels of reliability and user acceptance are critical for technical textiles, such as those used in PPE. While studies address washing reliability and field tests, they often overlook end user preferences regarding smart textiles. This paper presents a narrow fabric-based e-textile system co-developed by engineers, garment and textiles' manufacturers, and firefighters. It highlights material choices and integration methods, and evaluates the system's reliability, sustainability, and user experience, providing comprehensive insights into developing and analyzing e-textile products, particularly in the PPE field.

Validity and reliability of the Greek Migraine-Specific Quality of Life Questionnaire (MSQ Version 2.1-GR)

BackgroundTo assess the validity and reliability of the Migraine-Specific Quality of Life Questionnaire 2.1 (MSQv.2.1) in a group of Greek migraineurs.Design—sample—methodsThe Greek version of MSQv.2.1 (MSQv.2.1-GR), a self-report measure with 14 items in 3 domains (Role Restrictive (RR), Role Preventive (RP) and Emotional Function (EF)), was administered during a cross-sectional study to 141 Greek adult migraineurs and 135 controls without migraine or any other primary headache disorder, along with Migraine Disability Assessment Scale (MIDAS) and Short Form Health Survey (SF-12) to assess validity. MSQv.2.1-GR was re-administered in a group of participants with migraine two weeks afterwards to assess reliability. Content and construct validity was assessed using Intraclass Correlation Coefficient (ICC), Spearman rho, McDonald’s omega, Cronbach’s alpha. Confirmatory factor analysis (CFA) was used to test the latent structure of the MSQv.2.1-GR in migraineurs.ResultsA total of 276 adults participated in the study. Internal consistency of the three MSQv.2.1-GR scales RR, RP and EF yielded a range of McDonald’s omega from 0.832 to 0.923 (Cronbach’s alpha from 0.814 to 0.923). CFA confirmed the proposed three-factor MSQv.2.1-GR latent structure with acceptable goodness of fit indices and factor loadings. Correlations were established between MSQv2.1-GR component and MIDAS scores, showing moderate and statistically significant relationships (from − 0.519 to −0.562, all p < 0.001) for RR, RP and EF. Correlations between MSQv2.1-GR and SF-12 component scores were identified, with values from 0.1 to 0.4, indicating low to moderate associations. ICC was calculated at 0.997, indicating a high level of reliability between the measures. Notably, all MSQv2.1-GR scores (RR, RP, EF) were significantly higher in the controls compared to migraineurs (p < 0.001 for all scales). These findings suggest that MSQv2.1-GR is internally consistent, shows significant correlations with relevant measures, and is effective in discriminating controls from migraineurs.ConclusionMSQv2.1-GR is a valid and reliable tool to determine the effect migraine has on the quality of life of Greek-speaking migraineurs.

Bridging the gap in medical education: comparing analysis of light microscopy and virtual microscopy in histology.

This study aims to investigate the impact of virtual microscopy (VM) and light microscopy (LM) on the satisfaction of second-year medical students and how they affect student performance in different educational settings. The research involved 94 second-year students from Izmir Democracy University's School of Medicine, with criteria requiring enrollment in the 2021-2022 academic year and attendance of at least 80% in histology practical course. A paired two-tailed t-test was used for comparison, with a researcher-designed questionnaire for data collection. Cronbach's alpha was 0.894 for the LM questionnaire, and 0.918 for the VM questionnaire, indicating high level of reliability. LM scored higher in the questionnaire (p = 0.010), but VM showed higher exam averages (p = 0.013). The study found VM more effective in exams, with students showing high satisfaction with LM. VM's accessibility to histological preparations and its impact on learning levels and board exam success rates were noted. The study concludes that while VM is becoming essential in histology education due to its positive impact on exam performance and accessibility, LM remains highly valued by students for its hands-on experience and satisfaction levels.

Mind the Gap! Null Modals (and Other Functional Verbs) in Finite Complementation in Italo-Greek

Although Italo-Greek is characterized by a general retreat of infinitival complementation, it partly preserves the infinitive in restructuring contexts: a handful of functional auxiliaries—in an overt or covert form—allow for infinitival complements, with which they enter in a monoclausal union. Such a preservation also triggers consequences for finite complementation. Indeed, those predicates that still select for infinitival complements may lack finite complementation, resulting in only the lexical embedded verb surfacing instead of the complex sentence AUX + na + finite verb: δen du ékame típote ‘he could not do anything to him’ (lit. ‘he did not do anything to him’). I claim that such an absence—which gives rise to a semantic or even a syntactic gap—depends on the effects of the restructuring rule, which creates a high level of dependency and interlacing between the matrix and embedded verbs. When finite complements gradually replaced infinitival ones, though only sporadically, some predicates stopped selecting for finite complements, ultimately depriving the sentence of modal and other functional specifications.

Development and validation of the metaverse perception scale for nursing students

BackgroundThe use of Metaverse applications in nursing education is increasing every day and the evaluation of nursing students' perceptions of this new digital technology may guide interventions related to the use of the Metaverse. However, currently, no standardized instrument specifically designed to measure nursing students' perceptions of the Metaverse exists in Turkey. AimTo develop and validate the Metaverse Perception Scale for Turkish nursing students. MethodThis methodological study was carried out between March 1, 2023 and June 30, 2023 and its sample consisted of 770 nursing students who were enrolled in undergraduate nursing departments of universities in Turkey. The item pool was created based on a literature review and data were analyzed using descriptive statistics, item analysis, exploratory and confirmatory factor analysis, convergent and divergent validity, correlation analysis, internal consistency reliability and test-retest analysis. ResultsThe content validity index for the items ranged between 0.85 – 1.00. According to exploratory factor analysis, the eigenvalue of four factors was greater than one. These four factors explained 77.28 % of the total variance. In the scale model developed for this study, model fit was found to be acceptable for goodness of fit index:.921 and root mean square error of approximation:.064. χ2/sd: 1.659, normalized fit index:.961 and chi-square/degree of freedom revealed that model fit was at a good level and within the recommended value ranges. It was determined that the scale showed convergent and divergent validity and Cronbach's Alpha value ranged between 0.95 and 0.93 in the subscales. The Metaverse Perception Scale in Nursing Students was found to have a high level of test-retest reliability. ConclusionThis study showed that the scale, which consists of 24 items and four subscales, is a valid and reliable measurement tool that can be used to assess nursing students' perceptions of the Metaverse in the Turkish context. This scale can contribute to the evaluation of Turkish nursing students' perceptions of the Metaverse, as well as the effective management of processes related to Metaverse practices.

DIAGNOSTICS OF POSTURAL DISORDERS IN CHILDREN USING COMPUTER PHOTOMETRY

Actuality of the research. Literary and statistical data show that the level of morbidity among children in Ukraine remains high. Important to note that musculoskeletal system and connective tissue diseases take the fifth place among the morbidity structure, while the postural disorders and scoliosis remain the most urgent problem in school­age children. The aim of study is to check the computer photometry method efficiency for postural disorders diagnostics in school­age children with different levels of motor activity. Research methodology. In order to improve the dynamic control over the posture state, to increase the study objectification, to reduce the examination time and simplify the statistical material processing, a software complex for diagnosing posture disorders using the computer photometry method was used. Results. It was found that 25% of examined school­age children had postural disorders. Most often, postural disorders were observed within the age of 10­13 years, while in girls, postural disorders were registered 10% more often than in boys. Systematic exercise does not automatically guarantee the correct posture formation. In children­athletes, more pronounced indicators of angular anthropometric parameters asymmetry were registered, as a result of asymmetric back muscles load distribution. Children who did not exercise were more prone to kyphotic posture developing. Conclusions. As instrumental diagnostics, the computer photometry method has high level of informativeness and reliability, helps to maximize the data objectification and is effective in postural disorders detecting during as screening and as mass examinations.

Improving the reliability of nanosatellite swarms by adopting blockchain technology

Satellite swarm networks have occupied a prominent position in many modern applications due to their low cost, simplicity of design, and flexibility. Reliability is an influential factor in the design of satellite networks with different structures. Usually, small satellites are based on COST components, which may reduce continues operability due to the lack of using backup system on board the sagecraft. Any failure in one subsystem means a complete loss of the function and data stored in this subsystem; hence the need for a reliable and applicable solution for this matter is a crucial topic. Using the redundancy strategy in satellite swarm networks increases reliability and availability. Blockchain is characterized by using a distributed ledger which enables the database to be replicated across nodes in the network and results in increasing transparency, security, and trust. This paper suggests adoption of blockchain technology in distributed multi-satellite mission swarm networks to provide a high level of reliability and availability of the entire system; the blockchain is usually used to secure system transactions in multilayer approach by storage of the key parameters in more than one node; here we suggest the adoption of this approach not only to secure satellite network transaction, but also to increase system reliability so that failure of one node can be recovered by other nodes. We compared this approach with similar traditional networks that do not use blockchain. The results show a higher reliability efficiency of 95.3% for applying blockchain technology compared to 64.3% without the use of blockchain, as well as a higher availability of 99% compared to 91%.

Psychophysiological technologies using the biofeedback method: an analytical review

INTRODUCTION. There is high prevalence of post-stroke motor and neuropsychological disorders. However, they are usually considered without interrelation with each other, and rehabilitation methods are also considered in the context of a monodomain effect on specific functions. AIM. To analyze the available scientific evidence on the role of psychophysiological technologies with biofeedback in clinical medicine and medical rehabilitation. MATERIALS. 50 sources were analyzed, 25 of which are high-level evidence-based articles (randomized controlled trials, meta-analyses, systematic reviews) published in databases Elibrary.ru, Medline, Web of Science, PubMed and Scopus for the period of 2009–2024. RESULTS. The complex effect of the BFB method on the physical symptoms and psychological state of patients, as well as the possibility of using physiological indicators for adaptive biofeedback, has been studied. The greatest amount of evidence is available about the positive effect of technology using BFB on the psychoemotional state of patients and the state of the cardiovascular system. Significant results were obtained when using BFB-electromyographic-training in the complex therapy of headache and related emotional disorders. All studies have a high level of reliability of evidence and credibility of recommendations. Great progress has been made in the development of innovative psychophysiological technologies, including the use of hardware and software complexes, electroencephalography and neurointerfaces. CONCLUSION. Psychophysiological technologies with BFB demonstrate effectiveness in the rehabilitation of patients with psychosomatic disorders, borderline conditions and a number of neurological diseases (headache, epilepsy, spinal injury, stroke). Further research is needed to form an evidence base, clarify the mechanisms of action and algorithms of prescriptions, taking into account the physiological and psychological component of the therapeutic or rehabilitation process.

Development of operational standards procedures for maintenance and maintenance of public railway infrastructure infrastructure and electrical mechanical and architectural components in Wbs-based station buildings to improve maintenance and maintenance performance

A railway station is a place of departure and stoppage for trains. Poor, inappropriate maintenance and upkeep of infrastructure without strict supervision can result in physical damage to the infrastructure itself, thus losing its initial value and reducing the service life of the infrastructure. If the maintenance and upkeep of infrastructure in the transportation sector is not done properly, it can cause delays or, in the worst case, accidents. To ensure a high level of reliability and availability, the implementation of an effective maintenance program is very important. This is then clarified if poor maintenance and upkeep practices, such as in the transportation sector, can also affect the reliability of the transportation system and even cause life-threatening accidents. Damage or accidents that occur can also lower the company's image and customer or consumer trust. This research aims to develop Standard Operating Procedures (SOP) for maintenance and upkeep work on station buildings, architectural components, and mechanical electrical. The method used is based on a Literature Study, survey, and case study. The result of this research is the development of SOP maintenance and upkeep work on architectural components and mechanical electrical to improve maintenance performance.
