Authors: Zhu Jieting , Weng Huiting , Ou Peng , Li Lezhi
Published: April 2023

Background

With the advent of China’s aging population and the popularization of smartphones, there is a huge demand for smart elderly care apps. Along with older adults and their dependents, medical staff also need to use a health management platform to manage the health of patients. However, the development of health apps and the large and growing app market pose a problem of declining quality; in fact, important differences can be observed between apps, and patients currently do not have adequate information and formal evidence to discriminate among them.

Objective

The aim of this study was to investigate the cognition and usage status of smart elderly care apps among older individuals and medical staff in China.

Methods

From March 1, 2022, to March 30, 2022, we used the web survey tool Sojump to conduct snowball sampling through WeChat. The survey links were initially sent to communities in 23 representative major cities in China. We asked the medical staff of community clinics to post the survey link on their WeChat Moments. From April 1 to May 10, 2022, we contacted those who selected “Have used a smart elderly care app” in the questionnaire through WeChat for a request to participate in semistructured interviews. Participants provided informed consent in advance and interviews were scheduled. After the interviews, the audio recordings were transcribed into text and the emerging themes were analyzed and summarized.

Results

A total of 810 individuals participated in this study, 54.8% (n=444) of whom were medical staff, 33.1% (n=268) were older people, and the remaining participants were certified nursing assistants (CNAs) and community workers. Overall, 60.5% (490/810) of the participants had used a smart elderly care app on their smartphone. Among the 444 medical staff who participated in the study, the vast majority (n=313, 70.5%) had never used a smart elderly care app, although 34.7% of them recommended elderly care–related apps to patients. Among the 542 medical staff, CNAs, and community workers that completed the questionnaire, only 68 (12.6%) had used a smart elderly care app. We further interviewed 23 people about their feelings and opinions about smart elderly care apps. Three themes emerged with eight subthemes, including functional design, operation interface, and data security.

Conclusions

In this survey, there was a huge difference in the usage rate and demand for smart elderly care apps by the participants. Respondents are mainly concerned with app function settings, interface simplicity, and data security.

Published: April 2023

BACKGROUND

Fibromyalgia is a chronic pain syndrome characterized by persistent and widespread musculoskeletal pain. Telerehabilitation is a promising treatment for patients with fibromyalgia through long-term monitoring, intervention, supervision, consultation, and education.

OBJECTIVE

This study aimed to perform a comprehensive systematic review and meta-analysis of the efficacy and safety of telerehabilitation in patients with fibromyalgia.

METHODS

Randomized controlled trials (RCTs) related to fibromyalgia and telerehabilitation were systematically searched in the PubMed, PEDro, Cochrane Library, ScienceDirect, Ovid MEDLINE, Embase, and Web of Science databases from inception to November 13, 2022. Two independent researchers screened the literatures and evaluated the methodological quality using the Cochrane Risk of Bias Tool. The outcome measures included the Fibromyalgia Impact Questionnaire scale, pain intensity, depression, pain catastrophizing, quality of life (QoL), and adverse events. Pooled effect sizes were calculated by Stata SE 15.1; a fixed effects model was used when I2<50%, whereas a random effects model was used when I2≥50%.

RESULTS

A total of 14 RCTs with 1242 participants were included in this meta-analysis. The pooled results indicated that the telerehabilitation improved the Fibromyalgia Impact Questionnaire score (weighted mean difference –8.32, 95% CI –11.72 to –4.91; P<.001), pain intensity (standardized mean difference [SMD] –0.62, 95% CI –0.76 to –0.47; P<.001), depression levels (SMD –0.42, 95% CI –0.62 to –0.22; P<.001), pain catastrophizing (weighted mean difference –5.81, 95% CI –9.40 to –2.23; P=.001), and QoL (SMD 0.32, 95% CI 0.18 to 0.47; P<.001) in patients with fibromyalgia compared to control interventions. Only 1 RCT reported a mild adverse event of telerehabilitation; the other 13 RCTs did not mention this.

CONCLUSIONS

Telerehabilitation can improve the symptoms and QoL of fibromyalgia. However, the safety of telerehabilitation remains uncertain due to the lack of sufficient evidence for the management of fibromyalgia. More rigorously designed trials are needed in the future to verify the safety and efficacy of telerehabilitation in fibromyalgia.

Published: April 2023

BACKGROUND

Cyberchondria is characterized by repeated and compulsive online searches for health information, resulting in increased health anxiety and distress. It has been conceptualized as a multidimensional construct fueled by both anxiety and compulsivity-related factors and described as a “transdiagnostic compulsive behavioral syndrome,” which is associated with health anxiety, problematic internet use, and obsessive-compulsive symptoms. Cyberchondria is not included in the International Classification of Diseases 11th Revision or the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and its defining features, etiological mechanisms, and assessment continue to be debated.

OBJECTIVE

This study aims to investigate changes in the severity of cyberchondria during the COVID-19 pandemic and identify the predictors of cyberchondria at this time.

METHODS

Data collection started on May 4, 2020, and ended on June 10, 2020, which corresponds to the first wave of the COVID-19 pandemic in Europe. At the time the study took place, French-speaking countries in Europe (France, Switzerland, Belgium, and Luxembourg) all implemented lockdown or semilockdown measures. The survey consisted of a questionnaire collecting demographic information (sex, age, education level, and country of residence) and information about socioeconomic circumstances during the first lockdown (eg, economic situation, housing, and employment status) and was followed by several instruments assessing various psychological and health-related constructs. Inclusion criteria for the study were being at least 18 years of age and having a good understanding of French. Self-report data were collected from 725 participants aged 18-77 (mean 33.29, SD 12.88) years, with females constituting the majority (416/725, 57.4%).

RESULTS

The results showed that the COVID-19 pandemic affected various facets of cyberchondria: cyberchondria-related distress and compulsion increased (distress z=–3.651, P<.001; compulsion z=–5.697, P<.001), whereas the reassurance facet of cyberchondria decreased (z=–6.680, P<.001). In addition, COVID-19–related fears and health anxiety emerged as the strongest predictors of cyberchondria-related distress and interference with functioning during the pandemic.

CONCLUSIONS

These findings provide evidence of the impact of the COVID-19 pandemic on cyberchondria and identify factors that should be considered in efforts to prevent and manage cyberchondria at times of public health crises. In addition, they are consistent with a theoretical model of cyberchondria during the COVID-19 pandemic proposed in 2020. These findings have implications for the conceptualization and future assessment of cyberchondria.

Authors: Martínez-Miranda Juan , Meza Magallanes Martha Janet , Silva-Peña Cándido , Mercado Rivas Martha Xitlali , Figueroa-Varela María del Rocío , Sánchez Aranda Magda Lidiana
Published: April 2023

BACKGROUND

According to the World Health Organization, approximately 15% of the global population is affected by mental health or substance use disorders. These conditions contribute significantly to the global disease burden, which has worsened because of the direct and indirect effects of COVID-19. In Mexico, a quarter of the population between the ages of 18 and 65 years who reside in urban areas present a mental health condition. The presence of a mental or substance abuse disorder is behind a significant percentage of suicidal behaviors in Mexico, where only 1 in 5 of those who have these disorders receive any treatment.

OBJECTIVE

This study aims to develop, deploy, and evaluate a computational platform to support the early detection and intervention of mental and substance use disorders in secondary and high schools as well as primary care units. The platform also aims to facilitate monitoring, treatment, and epidemiological surveillance ultimately helping specialized health units at the secondary level of care.

METHODS

The development and evaluation of the proposed computational platform will run during 3 stages. In stage 1, the identification of the functional and user requirements and the implementation of the modules to support the screening, follow-up, treatment, and epidemiological surveillance will be performed. In stage 2, the initial deployment of the screening module will be carried out in a set of secondary and high schools, as well as the deployment of the modules to support the follow-up, treatment, and epidemiological surveillance processes in primary and secondary care health units. In parallel, during stage 2, patient applications to support early interventions and continuous monitoring will also be developed. Finally, during stage 3, the deployment of the complete platform will be performed jointly with a quantitative and qualitative evaluation.

RESULTS

The screening process has started, and 6 schools have been currently enrolled. As of February 2023, a total of 1501 students have undergone screening, and the referral of those students presenting a risk in mental health or substance use to primary care units has also started. The development, deployment, and evaluation of all the modules of the proposed platform are expected to be completed by late 2024.

CONCLUSIONS

The expected results of this study are to impact a better integration between the different levels of health care, from early detection to follow-up and epidemiological surveillance of mental and substance use disorders contributing to reducing the gap in the attention to these problems in the community.

Published: April 2023

BACKGROUND

Machine Learning-Enabled Clinical Information Systems (ML-CIS) have the potential to drive healthcare delivery and research. The Fast Healthcare Interoperability Resources (FHIR) data standard is increasingly applied in developing these systems. However, methods for applying FHIR to ML-CIS are variable.

OBJECTIVE

This study evaluates and compares the functionalities, strengths, and weaknesses of existing systems and proposes guidelines for optimizing future work with ML-CIS.

METHODS

Embase, PubMed, and Web of Science were searched for articles describing machine-learning systems used for clinical data analytics or decision support in compliance with FHIR standards. Information regarding each system’s functionality, data sources, formats, security, performance, resource requirements, scalability, strengths, and limitations were compared across systems.

RESULTS

39 articles describing FHIR-based ML-CIS were divided into three categories according to their primary focus: Clinical Decision Support Systems (CDSSs) (n=18), data management and analytic platforms (n=10), or auxiliary modules and application programming interfaces (n=11). Model strengths included novel use of cloud systems, Bayesian networks, visualization strategies, and techniques for translating unstructured or free text data to FHIR frameworks. Most intelligent systems lacked electronic health record interoperability and externally validated evidence of clinical efficacy.

CONCLUSIONS

Shortcomings in current ML-CIS can be addressed by incorporating modular and interoperable data management, analytic platforms, secure inter-institutional data exchange, and application programming interfaces with adequate scalability to support both real-time and prospective clinical applications using electronic health record platforms with diverse implementations.

Authors: Zou Minjie , Chen Aiming , Liu Zhenzhen , Jin Ling , Zheng Danying , Congdon Nathan , Jin Guangming
Published: April 2023

BACKGROUND

Asia accounts for more than half of the world’s population and carries a substantial proportion of the global burden blindness and vision impairment. Characterizing the burden, causes and determinants of blindness and vision impairment in Asia may make it possible to focus more on interventions and thereby reduce their occurrence in a more meaningful and sustained manner.

OBJECTIVE

To analyze and compare the burden, causes and determinants of blindness and vision loss across the sub-regions of Asia between 1990 and 2019.

METHODS

Numbers, age-standardized rate of disability-adjusted life years (DALYs) and prevalence of blindness and vision loss from six causes (Age-related macular degeneration, Cataract, Glaucoma, Near-vision impairment, Refractive error and other vision loss) among Asian countries were acquired from the Global Burden of Disease Study 2019 database. Difference by gender, age, geographic locations and socio-demographic index (SDI) were assessed.

RESULTS

In 2019, DALYs and prevalence of blindness and vision loss had risen by 90.1% and 116% compared with 1990, reaching 15.84 million (95% uncertainty interval (UI): 15.83 million, 15.85 million) and 506.71 million (95%UI: 506.68 million, 506.74 million), respectively. Meanwhile, the age-standardized rate of DALYs decreased from 445 (95%UI: 441, 449) to 376 (95%UI: 372, 380) per 100,000 population, while age-standardized prevalence fell from 11300 (95%UI: 11280, 11320) to 10930 (95%UI: 10910, 10950) per 100,000 population. Cataract, refractive error and near vision impairment were the three commonest causes. South Asia had the heaviest regional disease burden. The cataract burden ranked high in most Asian populations. Female sex, older age, and lower national SDI were associated with greater vision loss burden.

CONCLUSIONS

The vision loss burden remains high in Asian populations. Greater investment in ocular disease prevention and care by countries with lower socioeconomic status is needed, as are specific strategies targeting cataract, women and the elderly.
Words of Turkish Origin in English
Authors: Ismailova Farida
Published: April 2023

This paper presents and describes the process of borrowing of Turkic origin words into English. The languages of the world have been enriched at the expense of each other for millennia. Every day, new words are created in the languages of the world, and these words typically spread new concepts or refined concepts to neighboring or related languages. There is a very ancient history of borrowing words of Turkish origin into different languages. In English it was happened as a result of Mongol-Tatar invasions of Europe, these words began to enter in the form of terms. Basically, the words used by Byron in his oriental poems are described, the stylistic features of these words are revealed. Using the words of Turkic origin, Byron portrayed the oriental flavor, replenished the English vocabulary. In general, some Turkic words borrowed into English entered the Great Oxford Dictionary and are still used in everyday life.

How Universities Gaslight EDI&I Initiatives: Mapping Institutional Resistance to Structural Change
Authors: MacKenzie Megan , Sensoy Özlem , Johnson Genevieve Fuji , Sinclair Nathalie , Weldon Laurel
Published: April 2023

Despite the visibility of equity, diversity, inclusion, and Indigenization (EDI&I) discourses within large institutions, such as post-secondary institutions, research has chronicled only modest advancements on these stated values. Blocks to advancements in EDI&I stem, in part, from the structural nature of racist and sexist domination, and especially its embeddedness in both formal and informal norms of institutions. Based on a close examination of two EDI&I initiatives in university contexts, and direct experiences of “pushback” against these initiatives, this article conceptualizes institutional gaslighting, whereby universities paradoxically both embrace EDI&I discourse, on the one hand, while simultaneously deploying strategies that prevent dismantling systemic inequalities, on the other. A conceptualization of this dynamic is designed to help others identify and address forms of resistance, especially in settings of high stated value, and ultimately advance these values within large institutions.
Résumé
Malgré la visibilité de discours sur l’équité, la diversité, l’inclusion et l’indigénisation (EDII) dans de grandes institutions telles que les établissements postsecondaires, la recherche n’a relevé que des progrès modestes dans l’instauration de ces valeurs pourtant prisées. Les entraves à ces progrès ont pour cause le caractère structurel de la domination raciste et sexiste et surtout la persistance de cette domination dans les normes formelles et informelles des institutions. Cet article, en se fondant sur un examen attentif de deux initiatives EDII dans un contexte universitaire ainsi que sur un témoignage direct de résistance contre ces initiatives, décrit le détournement cognitif paradoxal par lequel les universités appuient d’une part les discours sur EDIItout en employant d’autre part des stratégies qui perpétuent les inégalités systémiques. Cet article présente une conceptualisation de cette dynamique afin d’aider les personnes impliquées à identifier et appliquer des moyens de résistance, surtout dans des contextes reconnus comme étant importants, et, au bout du compte, à promouvoir EDII au sein de grandes institutions.

Published: April 2023

It has been shown that the efficiency of engineering systems for creating a microclimate at livestock facilities is determined by the possibility of organizing the required thermal conditions in interaction with external temperature parameters of enclosing structures. (Research purpose) The research purpose is developing a method for calculating and modeling the thermal mode in the piglets’ location zone using an infrared irradiation panel in a system of diffusely absorbing and radiating surfaces. (Materials and methods) Considered the conditions of a comfortable thermal regime for young animals, the physical model of a piglet, the conditions of heat exchange. The areas of temperature change of the irradiating panel and the influence of the configuration of the optical characteristics of the system shell when creating comfortable conditions for keeping piglets, depending on the age and temperature parameters of the enclosing structures, were presented. (Results and discussion) It was found that the computational model of heat transfer of an animal on the example of a piglet in a system of isothermal diffusely absorbing and radiating surfaces serves as an extension of existing computational methods. (Conclusions) It has been shown that the mathematical model of heat exchange of an animal in a system of diffusely absorbing and radiating surfaces more fully reflects the interrelationships in the elements of the biotechnical system, this allows more accurately forming and maintaining the specified temperature conditions for the comfortable maintenance of young animals. We have obtained a functional model reflecting the dependences of the thermal state of piglets, taking into account their age, on the ambient temperature, the design parameters of the radiating panel and its temperature on the surface. The main correlations linking the conditions of thermal comfort of piglets with the temperature of the radiating surface of the panel, with the temperature and optical properties of the enclosing structures of the room were revealed. The scheme of the algorithm for calculating the surface temperature of the radiant panel was given. The range of panel surface temperature values was determined depending on the temperature of the enclosing structures for the conditions of a comfortable thermal condition of animals in the heating zone, taking into account their age.

The search for ways to save energy at livestock enterprises is one of the actual problems. The development of high-quality energy-saving lighting for the cultivation of farm animals is the basis for the successful development of the agro-industrial complex. It is determined that the prerequisite for the development of a new algorithm and methodology is the annual increase in the cost of electricity resources, which leads to an increase in the cost of livestock products. The parameters of lighting devices used for lighting livestock premises are not always justified, as a result of which the cost of the lighting system increases, its efficiency decreases. (Research purpose) The research purpose is developing a methodology and algorithm for the calculation of an effective lighting system. (Materials and methods) We selected the parameters of the lighting device that provide the smallest deviation of the maximum illumination and the unevenness of illumination from their set values in the livestock room. They showed one of the variants of progressive scientific and technical developments of the methodology and algorithm of the program in order to implement an energy-saving power supply mode. It was established that the development of the program will allow to calculate the design parameters of LED-based lighting installations, to ensure the quality of illumination on the working horizontal surface in the livestock room. We conducted theoretical studies at one of the livestock enterprises. (Results and discussion) We determined the main design parameters of the lighting device for a specific livestock room, in which the illumination norm is ensured and uneven lighting is excluded. (Conclusions) It was stated that the proposed design of the LED lighting device of the lamp will lead to a reduction in energy consumption, an increase in the efficiency of using electric energy and, accordingly, an increase in the productivity of livestock. They have shown that the use of the developed software will make it possible to increase the efficiency of calculations.
