Authors: Chae Han Joo , Kim Ji-Been , Park Gwanmo , O'Sullivan David Michael , Seo Jinwook , Park Jung-Jun
Published: August 2023

Background

Insufficient physical activity due to social distancing and suppressed outdoor activities increases vulnerability to diseases like cardiovascular diseases, sarcopenia, and severe COVID-19. While bodyweight exercises, such as squats, effectively boost physical activity, incorrect postures risk abnormal muscle activation joint strain, leading to ineffective sessions or even injuries. Avoiding incorrect postures is challenging for novices without expert guidance. Existing solutions for remote coaching and computer-assisted posture correction often prove costly or inefficient.

Objective

This study aimed to use deep neural networks to develop a personal workout assistant that offers feedback on squat postures using only mobile devices—smartphones and tablets. Deep learning mimicked experts’ visual assessments of proper exercise postures. The effectiveness of the mobile app was evaluated by comparing it with exercise videos, a popular at-home workout choice.

Methods

Twenty participants were recruited without squat exercise experience and divided into an experimental group (EXP) with 10 individuals aged 21.90 (SD 2.18) years and a mean BMI of 20.75 (SD 2.11) and a control group (CTL) with 10 individuals aged 22.60 (SD 1.95) years and a mean BMI of 18.72 (SD 1.23) using randomized controlled trials. A data set with over 20,000 squat videos annotated by experts was created and a deep learning model was trained using pose estimation and video classification to analyze the workout postures. Subsequently, a mobile workout assistant app, Home Alone Exercise, was developed, and a 2-week interventional study, in which the EXP used the app while the CTL only followed workout videos, showed how the app helps people improve squat exercise.

Results

The EXP significantly improved their squat postures evaluated by the app after 2 weeks (Pre: 0.20 vs Mid: 4.20 vs Post: 8.00, P=.001), whereas the CTL (without the app) showed no significant change in squat posture (Pre: 0.70 vs Mid: 1.30 vs Post: 3.80, P=.13). Significant differences were observed in the left (Pre: 75.06 vs Mid: 76.24 vs Post: 63.13, P=.02) and right (Pre: 71.99 vs Mid: 76.68 vs Post: 62.82, P=.03) knee joint angles in the EXP before and after exercise, with no significant effect found for the CTL in the left (Pre: 73.27 vs Mid: 74.05 vs Post: 70.70, P=.68) and right (Pre: 70.82 vs Mid: 74.02 vs Post: 70.23, P=.61) knee joint angles.

Conclusions

EXP participants trained with the app experienced faster improvement and learned more nuanced details of the squat exercise. The proposed mobile app, offering cost-effective self-discovery feedback, effectively taught users about squat exercises without expensive in-person trainer sessions.

Authors: Baron Ruth , Hamdiui Nora , Helms Yannick B , Crutzen Rik , Götz Hannelore M , Stein Mart L
Published: August 2023

Background

The COVID-19 pandemic revealed that with high infection rates, health services conducting contact tracing (CT) could become overburdened, leading to limited or incomplete CT. Digital CT support (DCTS) tools are designed to mimic traditional CT, by transferring a part of or all the tasks of CT into the hands of citizens. Besides saving time for health services, these tools may help to increase the number of contacts retrieved during the contact identification process, quantity and quality of contact details, and speed of the contact notification process. The added value of DCTS tools for CT is currently unknown.

Objective

To help determine whether DCTS tools could improve the effectiveness of CT, this study aims to develop a framework for the comprehensive assessment of these tools.

Methods

A framework containing evaluation topics, research questions, accompanying study designs, and methods was developed based on consultations with CT experts from municipal public health services and national public health authorities, complemented with scientific literature.

Results

These efforts resulted in a framework aiming to assist with the assessment of the following aspects of CT: speed; comprehensiveness; effectiveness with regard to contact notification; positive case detection; potential workload reduction of public health professionals; demographics related to adoption and reach; and user experiences of public health professionals, index cases, and contacts.

Conclusions

This framework provides guidance for researchers and policy makers in designing their own evaluation studies, the findings of which can help determine how and the extent to which DCTS tools should be implemented as a CT strategy for future infectious disease outbreaks.

Authors: Guinez-Molinos Sergio , Buendía-García Félix , Sierra-Rodríguez José-Luis , Gayoso-Cabada Joaquín , González-Díaz Jaime
Published: August 2023

Background

The creation of computer-supported collaborative clinical cases is an area of educational research that has been widely studied. However, the reuse of cases and their sharing with other platforms is a problem, as it encapsulates knowledge in isolated platforms without interoperability. This paper proposed a workflow ecosystem for the collaborative design and distribution of clinical cases through web-based computing platforms that (1) allow medical students to create clinical cases collaboratively in a dedicated environment; (2) make it possible to export these clinical cases in terms of the Health Level 7 (HL7) Fast Healthcare Interoperability Resources (FHIR) interoperability standard; (3) provide support to transform imported cases into learning object repositories; and (4) use e-learning standards (eg, Instructional Management Systems Content Packaging [IMS-CP] or Sharable Content Object Reference Model [SCORM]) to incorporate this content into widely-used learning management systems (LMSs), letting medical students democratize a valuable knowledge that would otherwise be confined within proprietary platforms.

Objective

This study aimed to demonstrate the feasibility of developing a workflow ecosystem based on IT platforms to enable the collaborative creation, export, and deployment of clinical cases.

Methods

The ecosystem infrastructure for computer-supported collaborative design of standardized clinical cases consists of three platforms: (1) Mosaico, a platform used in the design of clinical cases; (2) Clavy, a tool for the flexible management of learning object repositories, which is used to orchestrate the transformation and processing of these clinical cases; and (3) Moodle, an LMS that is geared toward publishing the processed clinical cases and delivering their course deployment stages in IMS-CP or SCORM format. The generation of cases in Mosaico is exported in the HL7 FHIR interoperability standard to Clavy, which is then responsible for creating and deploying a learning object in Moodle.

Results

The main result was an interoperable ecosystem that demonstrates the feasibility of automating the stages of collaborative clinical case creation, export through HL7 FHIR standards, and deployment in an LMS. This ecosystem enables the generation of IMS-CPs associated with the original Mosaico clinical cases that can be deployed in conventional third-party LMSs, thus allowing the democratization and sharing of clinical cases to different platforms in standard and interoperable formats.

Conclusions

In this paper, we proposed, implemented, and demonstrated the feasibility of developing a standards-based workflow that interoperates multiple platforms with heterogeneous technologies to create, transform, and deploy clinical cases on the web. This achieves the objective of transforming the created cases into a platform for web-based deployment in an LMS.

Authors: Labarta José I , Dimitri Paul , Keiser Matthew , Koledova Ekaterina , Rivera-Romero Octavio
Published: August 2023

Background

Digital solutions targeting children’s health have become an increasingly important element in the provision of integrated health care. For the treatment of growth hormone deficiency (GHD), a unique connected device is available to facilitate the delivery of recombinant human growth hormone (r-hGH) by automating the daily injection process and collecting injection data such that accurate adherence information is available to health care professionals (HCPs), caregivers, and patients. The adoption of such digital solutions requires a good understanding of the perspectives of HCPs as key stakeholders because they leverage data collection and prescribe these solutions to their patients.

Objective

This study aimed to evaluate the third generation of the easypod device (EP3) for the delivery of r-hGH treatment from the HCP perspective, with a focus on perceived usefulness and ease of use.

Methods

A qualitative study was conducted, based on a participatory workshop conducted in Zaragoza, Spain, with 10 HCPs experienced in the management of pediatric GHD from 7 reference hospitals in Spain. Several activities were designed to promote discussion among participants about predefined topics based on the Technology Acceptance Model and the Unified Theory of Acceptance and Use of Technology to provide their perceptions about the new device.

Results

Participants reported 2 key advantages of EP3 over previous easypod generations: the touch screen interface and the real-time data transmission functionality. All participants (10/10, 100%) agreed that the new device should be part of a digital health ecosystem that provides complementary functionalities including data analysis.

Conclusions

This study explored the perceived value of the EP3 autoinjector device for the treatment of GHD by HCPs. HCPs rated the new capabilities of the device as having substantial improvements and concluded that it was highly recommendable for clinical practice. EP3 will enhance decision-making and allow for more personalized care of patients receiving r-hGH.
Investigating Individuals’ Preferences in Determining the Functions of Smartphone Apps for Fighting Pandemics: Best-Worst Scaling Survey Study
Authors: Xu Richard Huan , Shi Lushaobo , Shi Zengping , Li Ting , Wang Dong
Published: August 2023

Background

Smartphone apps have been beneficial in controlling and preventing the COVID-19 pandemic. However, there is a gap in research surrounding the importance of smartphone app functions from a user’s perspective. Although the insights and opinions of different stakeholders, such as policymakers and medical professionals, can influence the success of a public health policy, any strategy will face difficulty in achieving the expected effect if it is not based on a method that users can accept.

Objective

This study aimed to assess the importance of a hypothetical smartphone app’s functions for managing health during a pandemic based on the perspective of user preferences.

Methods

A cross-sectional and web-based survey using the best-worst scaling (BWS) method was used to investigate the general population’s preferences for important smartphone app functions. Participants were recruited from a professional surveying company’s web-based surveying panel. The attributes of the BWS questionnaire were developed based on a robust process, including literature review, interviews, and expert discussion. A balanced incomplete block design was used to construct the choice task to ensure the effectiveness of the research design. Count analysis, conditional logit model analysis, and mixed logit analysis were used to estimate preference heterogeneity among respondents.

Results

The responses of 2153 participants were eligible for analysis. Nearly 55% (1192/2153) were female, and the mean age was 31.4 years. Most participants (1765/2153, 81.9%) had completed tertiary or higher education, and approximately 70% (1523/2153) were urban residents. The 3 most vital functions according to their selection were “surveillance and monitoring of infected cases,” “quick self-screening,” and “early detection of infected cases.” The mixed logit regression model identified significant heterogeneity in preferences among respondents, and stratified analysis showed that some heterogeneities varied in respondents by demographics and COVID-19–related characteristics. Participants who preferred to use the app were more likely to assign a high weight to the preventive functions than those who did not prefer to use it. Conversely, participants who showed lower willingness to use the app tended to indicate a higher preference for supportive functions than those who preferred to use it.

Conclusions

This study ranks the importance of smartphone app features that provide health care services during a pandemic based on the general population’s preferences in China. It provides empirical evidence for decision-makers to develop eHealth policies and strategies that address future public health crises from a person-centered care perspective. Continued use of apps and smart investment in digital health can help improve health outcomes and reduce the burden of disease on individuals and communities.

Authors: Meksawasdichai Sununtha , Lerksuthirat Tassanee , Ongphiphadhanakul Boonsong , Sriphrapradang Chutintorn
Published: August 2023

Background

Twitter has become a popular platform for individuals to broadcast their daily experiences and opinions on a wide range of topics and emotions. Tweets from patients with cancer could offer insights into their needs. However, limited research has been conducted using Twitter data to understand the needs of patients with cancer despite the substantial amount of health-related data posted on the platform daily.

Objective

This study aimed to uncover the potential of using Twitter data to understand the perspectives and experiences of patients with thyroid cancer at a global level.

Methods

 This retrospective descriptive study collected tweets relevant to thyroid cancer in 2020 using the Twitter scraping tool. Only English-language tweets were included, and data preprocessing was performed to remove irrelevant tweets, duplicates, and retweets. Both tweets and Twitter users were manually classified into various groups based on the content. Each tweet underwent sentiment analysis and was classified as either positive, neutral, or negative.

Results

A total of 13,135 tweets related to thyroid cancer were analyzed. The authors of the tweets included patients with thyroid cancer (3225 tweets, 24.6%), patient’s families and friends (2449 tweets, 18.6%), medical journals and media (1733 tweets, 13.2%), health care professionals (1093 tweets, 8.3%), and medical health organizations (940 tweets, 7.2%), respectively. The most discussed topics related to living with cancer (3650 tweets, 27.8%), treatment (2891 tweets, 22%), diagnosis (1613 tweets, 12.3%), risk factors and prevention (1137 tweets, 8.7%), and research (953 tweets, 7.3%). An average of 36 tweets pertaining to thyroid cancer were posted daily. Notably, the release of a film addressing thyroid cancer and the public disclosure of a news reporter’s personal diagnosis of thyroid cancer resulted in a significant escalation in the volume of tweets. From the sentiment analysis, 53.5% (7025/13,135) of tweets were classified as neutral statements and 32.7% (4299/13,135) of tweets expressed negative emotions. Tweets from patients with thyroid cancer had the highest proportion of negative emotion (1385/3225 tweets, 42.9%), particularly when discussing symptoms.

Conclusions

 This study provides new insights on using Twitter data as a valuable data source to understand the experiences of patients with thyroid cancer. Twitter may provide an opportunity to improve patient and physician engagement or apply as a potential research data source.
Vertical variability of the intensity of the frontal zones of the Norwegian Sea
Authors: Travkin Vladimir , Akhtyamova Avelina
Published: August 2023

The Norwegian Sea is the meeting place of warm and salty Atlantic waters with cold and fresh Arctic waters. The thermal and haline frontal zones (FZs) formed as a result of this interaction are areas of increased horizontal gradients of physical, chemical, and biological parameters, and have a significant impact on regional circulation. Many mesoscale eddies are generated in the FZs which are actively involved in the eddy dynamics of the Norwegian Sea. The aim of this work is to analyze the spatio-temporal variability of the vertical structure of FZs in the Norwegian Sea, as well as the eddies that form within their boundaries. The work uses data from the oceanic reanalysis GLORYS12V1, as well as the Atlas of Mesoscale Eddies "Mesoscale Eddy Trajectory Atlas product META 3.2 DT" for the period 1993--2021. We analyze the average depth and thickness of FZs, the vertical distribution of their thermohaline gradients and areas. The work examines the seasonal and interannual variability of the volumes of thermal and haline FZs, the seasonal and interannual variability of mesoscale eddies, their spatial distribution, trajectories, and main parameters. In some areas, deepening of FZs has been established, and their thickness can reach 900 m. The presence of significant haline gradients in the layer of 250--750 m has been found, while thermal FZs can be traced vertically up to 1000 m compared with haline FZs. In some FZs, the interannual variability may exceed the seasonal one. The greatest variability of haline FZs can be traced in the autumn period, and the smallest -- in the winter--spring. It is noticeable in the summer period that thermal FZs weaken. Eddies can leave the boundaries of the FZs and move away from the place of origin for hundreds of kilometers. The number and lifetime of cyclones exceed similar estimates for anticyclones, while anticyclones travel long distances compared to cyclones.

Published: August 2023

Mudskippers are commonly cryptic species, making identification based solely on morphological characteristics challenging. This study used the DNA barcoding method to identify mudskipper species based on the COI mitochondrial gene. The analysis revealed two distinct species, P. kalolo (20 samples) and P. argentilineatus (3 samples) with high GC contents ranging from 42.94-45.2%. The genetic divergence analysis of P. kalolo showed that they divided into two clades, while P. argentilineatus is divided into three clades with two of the clades (C and D)  still conspecific groups, and those two clades with clade E exhibit a genetic distance greater than 3.5%, suggesting the presence of cryptic species. These findings provide valuable insights into the intraspecies genetic diversity of mudskippers in Indonesia, which could have essential implications for conservation efforts and highlight the potential of DNA barcoding as a powerful tool for the identification of cryptic species. Further research combining molecular and morphological identification could lead to a more comprehensive understanding of species identification and help address the challenges posed by cryptic species.

The date of the paleoclimate event was ascertained using a biostratigraphic analysis. The thickness of the Oyo Formation was measured using measurements with a Jacob stick method, yielding a thickness of 80.8 meters and 23 rock samples. In the Southern Mountains Zone,  new result of the age of the upper part of the Oyo Formation by biostratigraphy investigation of the hill Late Miocene (9.79 Ma to 5.78 Ma). Biostratigraphic investigation in the Oyo River revealed 28 species and 9 genera, with two datums. The study area was classified into three biozonations based on the datum found Globorotalia acostaensis/M13a/N16 zone, the lower Globorotalia plesiotumida/M13b/N17 zone, and the upper Globigerinoides conglobatus/M14/N17 zone. The results of a paleoclimate analysis on the Oyo River Section show a general cooling tendency in the study area. Seven paleoclimate zones can be determined from these trends consisting of four warm and three cold zones. Zone I (warm), zone II (cold), zone III (warm), and zone IV (cold) have the coldest peak in the study region in 8.3 Ma, zone V (warm), and zone VI (cold), followed by zone VII (warm). Based on the correlation with other studies (South China Sea, Pacific Ocean, Oyo River, Ngalang River, and Ngioro Section), paleoclimate events in the study area occur globally.
Higher Education Means More than Vocational Training in the 21st Century
Authors: Lyu Yue
Published: August 2023

Based on theoretical approach of Biesta and Nussbaum, this essay argues that higher education means more than vocational training in the 21st century. The article first contributes to different insights into the area of educational purposes and policy. Then it analyzes the specific issue within this theme-vocationalism in higher education-with the help of the two theoretical tools, arguing that Biesta’s approach offers a more appropriate and fuller explanation for the issue. Maintaining the diversity of purposes of higher education can make it better function in the social system and prevent us from getting lost in the way of discovering its true value. Finally, there are two recommendations for thinking about the ultimate value of education regardless of its forms.

Authors: NAIR HEMA A. , GADHIRAJU GAAYATHRI , SUNNY GUNDETI
Published: August 2023

Objective: The objective of the present work was to develop an orodispersible tablet of loratadine, an orally active, non-sedating anti-histaminic, belonging to BCS Class II. The drug was prepared as a solid dispersion using Soluplus® as carrier and formulated into an optimal tablet using Design of Experiments.
Methods: Solid dispersions of loratadine with varying ratios of Soluplus® were prepared by solvent evaporation and subjected to solubility study in simulated salivary fluid. Selected composition was characterized by differential scanning calorimetry and X-ray diffraction and formulated into an orodispersible tablet by direct compression after addition of suitable excipients. DOE based on a full factorial design was used to optimize the product using a trial version of JMP software, so as to obtain a tablet with low friability, rapid disintegration and maximal drug dissolution within 5 min. The optimized tablet was prepared and evaluated for several attributes, including in vivo disintegration and palatability.
Results: A solid dispersion prepared with a 1: 4 ratio of loratadine: Soluplus® was found to show a 130-fold increase in drug solubility in the simulated salivary fluid. X-ray diffraction revealed loratadine in amorphous form. The exercise using DOE for optimization of the orodispersible tablet formula served to balance the proportion of crospovidone as super disintegrant and PVP as dry binder and yielded a formulation with good mechanical strength, rapid in vitro disintegration (39 sec) and dissolution of 93.78% of the drug within 5 min. When evaluated in vivo, the tablets were found to disintegrate in about 60 secs and were reported to be palatable.
Conclusion: A patient-friendly dosage form containing a highly soluble form of loratadine was prepared and could be of potential benefit in offering quick relief from allergic conditions.

Authors: BADKUR DEEPIKA , SINGH SUCHITA
Published: August 2023

Objective: To assess immunization coverage in up to 23 mo old children with respect to economic status and Knowledge, Attitude and Practice of mothers regarding immunization.
Methods: A cross-sectional study was conducted, including 125 mothers who had children aged grouped between 0-23 mo from 7 fully functional anganwadis. The data was collected using a semi-structured questionnaire and analyzed using Microsoft Excel. The chi-square test/Fisher exact test was applied, and results were presented in the form of tables. Findings were compared against standards and/or findings from similar studies and discussed.
Results: Immunization coverage was found to be 79%. Almost 85% of mothers believe that the vaccine prevents communicable diseases, and 82.4% agree that immunization at birth is important. The majority of mothers (92%) agreed that their children should be vaccinated as soon as possible. Related to the attitude of mothers towards immunization, a maximum (93.6%) percent of mothers believed that even a healthy child should be fully immunized for protection from diseases, and 86% had no fear related to vaccinating their child. More than half (72.8%) of mothers informed that they would contact anganwadi workers for the next dose of vaccine. Almost 62% of mothers agreed to breastfeed their children after an oral vaccine, and 87.2% of mothers said that they would take their children for regular vaccination. No association (P>0.05) was found between the child’s immunization status and the socioeconomic status of the family.
Conclusion: The study concludes immunization coverage is 79% and there is a positive attitude towards immunization, but less knowledge is related to the age appropriate vaccine. So services focusing on immunization education and provision need to be improved.

Indonesia is a country with many different tribes and cultures. Each region has its own characteristics that will be imprinted in the memory of each individual, which will eventually become an icon of a particular area. One of the city's icons is Ondel-Ondel from Betawi. Ondel-Ondel are giant dolls that are understood by the Betawi people as sacred culture and are used in ritual sacrifices to ancestral spirits. At first Ondel-Ondel was created as a way to repel reinforcements from the Betawi tribe. However, now everything is different. Ondel-Ondel is no longer considered sacred. The existence of Ondel-Ondel art is no longer used for cultural activities but is misused in street activities. This means that there has been a change in this Betawi Ondel-Ondel art. These changes are caused by social conditions. This is why efforts to increase awareness of local culture need to be increased. Changing times have formed new patterns of thinking about things that are traditional and not all people know the meaning behind the Betawi Ondel-Ondel art. The research method used is a qualitative method, data collection is done through literature studies, observations and interviews.
