RESUMO

BACKGROUND: We aimed to explore the overall network structure of problematic smartphone use symptoms assessed by smartphone addiction scale-short version (SAS-SV) and to identify which items could play important roles in the network. METHODS: 487 college and university students filled out the study questionnaire, including SAS-SV. We constructed a regularized partial correlation network among the 10 items of SAS-SV. We calculated three indices of node centrality: strength, closeness, and betweenness, to quantify the importance of each SAS-SV item. RESULTS: We identified 34 edges in the estimated network. In the given network, one item pertaining to withdrawal symptom hadthe highest strength and high closeness centrality. Additionally, one item related to preoccupation was also found to have high centrality indices. CONCLUSION: Our results indicating the central role of one withdrawal symptom and one preoccupation symptom in the symptom network of problematic smartphone use in young adults were in line with a previous study targeting school-age children. Longitudinal study designs are required to elicit the role of these central items on the formation and maintenance of this behavioral problem.

RESUMO

Background: Zero-time Exercise (ZTEx), a simple strength- and stamina-enhancing physical activity (PA) requiring no extra equipment, can potentially increase PA and fitness. This pilot trial examined the feasibility and potential effectiveness of a smartphone ZTEx intervention to promote PA and fitness in patients with coronary heart disease (CHD). Methods: A parallel-group assessor-blinded pilot randomized controlled trial was conducted on Chinese patients with stable coronary heart disease (CHD) in three cardiology clinics. The experimental group received a 15-min brief individual face-to-face session and a 12-week ZTEx instant messaging with 28 picture e-messages and a smartphone ZTEx application (ZTExApp). The control group received the same duration of individual session and number and format of e-messages, but the content was healthy eating and breathing exercise. The feasibility was assessed based on: attrition rate, usage, response rate and perception of the intervention. The outcome evaluation included primary outcome (PA), fitness, exercise self-efficacy and intention, perceived happiness and health, and quality of life. A linear mixed model was used with intention-to-treat analysis adjusting for sex, age and baseline values. A semi-structured interview was conducted to collect feedback from the experiment group. Results: One hundred thirty-nine patients (mean age 59.8 ± 6.6; 71.2% male) were randomized to the experimental group (n = 70) or control group (n = 69), and 80% (56/70) and 82% (57/69) of patients completed the 12-week follow-up assessment, respectively. The attrition rate was 18.7%. The experimental group reported that ZTEx was feasible to integrate PA into their daily life and appreciated the picture e-messages, and 95% of them sent feedback to us, but only 19.6% (13/70) of the participants entered their PA information into the e-diary of the ZTExApp. The experimental group had a significantly greater increase in time spent walking [mean difference (95% CI): 155.3 (10.1, 300.4), P = 0.04, Cohen's d = 0.34] than the control group. Conclusions: This pilot study showed using a brief ZTEx face-to-face session with picture e-messages empowered patients with CHD to integrate PA into daily life. Future definitive trials with a longer follow-up and a more user-friendly ZTExApp interface are necessary to determine the effectiveness of the smartphone ZTEx intervention in enhancing PA and related outcomes. Trial Registration: The research protocol was registered at the Hong Kong University Clinical Trials Registry (HKUCTR) on 22 Jul 2016 (Study identifier: HKUCTR-2165) and was also retrospectively registered at the National Institutes of Health (identifier number: NCT03464331) on 14 March 2018.

RESUMO

BACKGROUND: Unhealthy smartphone habits use can impair the health of young children. Smartphone use among young children is affected by several factors of which the most important is parental knowledge pertains to smartphone exposure among young children. In Jordan, no studies have focused on this factor. METHOD: A nation-wide cross-sectional survey was distributed to parents of children aged <6 years to assess parental knowledge of smartphone exposure among young children and examine its correlates in Jordan. An online self-reporting questionnaire was administered via Survey Monkey and posted on social media platforms in June 2020. RESULTS: A total of 2,781 Jordanian parents completed the survey. During the pandemic the daily hours of Smartphone use among children were significantly higher than prior the coronavirus-2019 (COVID-19) pandemic (2.12 vs. 1.7 h). More than half the children exceeded the recommended daily hours of use. These results were positively associated with increased smartphone use among parents. Overall, the parents proved knowledgeable regarding the effects of excessive smartphone exposure on the health of their children. However, a knowledge deficit was evident in two areas: parental controls on smartphone and safe levels of infant smartphone exposure. The mothers possessed a significantly higher level of knowledge than the fathers. CONCLUSION: The results suggest that, in the context Jordan, increasing parental knowledge has the potential to reduce smartphone exposure among young children. Awareness campaigns are needed to enhance parental knowledge of smartphone exposure among young children and the use of parental controls on smartphones.

RESUMO

Introduction: Dental anxiety is a multivariate phenomenon that regularly occurs during a dental procedure. Although it may lead to patients' safety concerns and adverse events in routine treatment, it is often ignored. The purpose of this research is to develop a novel WeChat Applet for dental anxiety (WADA) with the following features and aims: (1) to help patients with dental anxiety management; (2) provide patient with a physical status self-evaluation; and(3) provide a platform for online assessment and tele-consultancy by dentists. We aimed to test and verify whether such an applet could play a beneficial role before and after a dental procedure and facilitate management of high-risk patients during the COVID-19 pandemic. Materials and methods: During the 12-month survey period (August 2020 to July 2021), a total of 180 patients aged 3-74 years from eight different cities (n = 180 at the end of treatment, n = 25 for the System Usability Scale (SUS) and follow-up interview) and 20 medical staff from eight different cities (n =20 for follow-up interview) were evaluated by WADA. At the end of the survey period, the results of the interviews were analyzed thematically. Results: WADA assessment results from 180 patients and follow-up interview results from 45 participants were analyzed. In this study with a male to female ratio of 2:3, 75% were found to be suffering from dental anxiety, 86% were found with postoperative complications, and 11 cases were found to have contraindications to surgery. The total SUS score for WADA is 72.25 above the mean score, proving that WADA is a relevant and useful tool before and after dental treatment. Based on the results of the interviews, the following themes were identified: patient satisfaction; dentists' effectiveness; multi-center data integration; and increase its frequency of usage. Conclusions: The WADA was developed for dental procedures and is effective for reducing treatment risks, improving patients' satisfaction and dentists' convenience, especially in terms of facilitating management of high-risk patient during the COVID-19 pandemic.

RESUMO

As the number of smartphone use by older adults increases, investigating the effects of smartphone use on health outcome become important in healthcare. This study aimed to investigate the effects of smartphone use on life satisfaction and the mediating role of depressive symptoms in older adults. This is a secondary data analysis study using the 2017 Korean Media Panel Survey. A total of 2071 respondents aged 65 years and older were analyzed to examine the effects of mobile phone type (no mobile phone/2G phone/smartphone) on life satisfaction. Among the respondents, data from 680 smartphone owners were analyzed to find the effects of the level of smartphone use on life satisfaction. The 2G mobile phone and smartphone owner groups showed significant positive effects on life satisfaction compared with the no mobile phone group, respectively. The level of smartphone use showed significant positive effects on life satisfaction. Depressive symptoms played a mediating role in both models. Smartphone use showed positive effects on life satisfaction in older adults. Nurses should promote the well-being of older adults and minimize the digital health gap in the future by increasing older adults' smartphone use through multi-level approaches.

RESUMO

PURPOSE: An inclinometer smartphone application has been developed to enable the measurement of the angle of trunk inclination (ATI) to detect trunk surface asymmetry. The objective was to determine the reliability and validity of the smartphone app in the hands of non-professionals. METHODS: Three non-professional observers and one expert surgeon measured maximum ATI twice in a study involving 69 patients seen in the spine clinics to rule out scoliosis or for regular follow-up (10-18 y.o., Cobb [0°-58°]). Observers were parents not familiar with scoliosis screening nor use of an inclinometer. They received training from a 4-minute video. Intra and inter-observer reliability was determined using the generalizability theory and validity was assessed from intraclass correlation coefficients (ICC), agreement with the expert on ATI measurements using Bland-Altman analysis, and correct identification of the threshold for consultation (set to ≥6° ATI). RESULTS: Intra-observer and inter-observer reliability coefficients were excellent ϕ = 0.92. The standard error of measurement was 1.5° (intra-observer, 2 measurements) meaning that a parent may detect a change of 4° between examinations 95% of the time. Comparison of measurements between non-professionals and the expert resulted in ICC varying from 0.82 [0.71-0.88] to 0.84 [0.74-0.90] and agreement on the decision to consult occurred in 83 to 90% of cases. CONCLUSION: The use of a smartphone app resulted in excellent reliability, sufficiently low standard error of measurement (SEM) and good validity in the hands of non-professionals. The device and the instructional video are adequate means to allow detection and regular examination of trunk asymmetries by non-professionals.

RESUMO

α-Amanitin is often considered the most poisonous mushroom toxin produced by various mushroom species, which are hard to identify from edible, non-toxic mushrooms. Conventional detection methods require expensive and bulky equipment or fail to meet high analytical sensitivity. We developed a smartphone-based fluorescence microscope platform to detect α-amanitin from dry mushroom tissues. Antibody-nanoparticle conjugates were captured by immobilized antigen-hapten conjugates while competing with the free analytes in the sample. Captured fluorescent nanoparticles were excited at 460 nm and imaged at 500 nm. The pixel numbers of such nanoparticles in the test zone were counted, showing a decreasing trend with increasing analyte concentration. The detection method exhibited a low detection limit (1 pg/mL), high specificity, and selectivity, allowing us to utilize a simple rinsing for toxin extraction and avoiding the need for high-speed centrifugation. In addition, this assay's short response time and portable features enable field detection of α-amanitin from amanitin-producing mushrooms.

RESUMO

The coexistent pollution of multiple mycotoxins displays a synergistic toxicity effect that significantly threatens human health. Therefore, it is essential to establish a rapid detection method for multi-mycotoxins in food. In this study, red, green, and blue latex microspheres (LMs) were applied as the aflatoxin B1 (AFB1), T-2 toxins (T-2), and zearalenone (ZEN) antibodies labeled tracer, respectively. Based on the principle of spatial resolution, a rainbow "traffic light" pattern latex microspheres lateral flow immunoassay (LMs-LFIA) integrated with a portable and user-friendly smartphone-based device was first developed to detect three kinds of mycotoxins simultaneously. The cut-off values of the method for AFB1/T-2/ZEN in cereals were 1/15/40 µg kg-1, the limits of detection were 0.04/0.40/1.21 µg kg-1, respectively. The recoveries ranged from 82.1% to 107.5%, with the coefficient of variation from 3.0% to 8.1%. A parallel analysis in 26 naturally contaminated cereal samples was confirmed by commercial ELISA kits; the results showed a good correlation (R2>0.99), indicating the practical reliability of the rainbow LMs-LFIA. This method provided a visually enjoyable, portable, and sensitive detection mode for multi-target detection of mycotoxins or other small molecule hazard factors in food.

RESUMO

Considering the complexities and speed of modern food chains, there is an increasing demand for point-of-need detection of food contaminants, particularly highly regulated chemicals and carcinogens such as aflatoxin B1. We report a user-friendly smartphone-based magneto-immunosensor on carbon black modified electrodes for point-of-need detection of aflatoxin B1 in cereals. For buffered analyte solutions and a corn extract sample, the assay demonstrated a low limit of detection of 13 and 24 pg/mL, respectively. The assay was also highly reproducible, exhibiting mean relative standard deviations of 3.7% and 4.0% for the buffered analyte and corn extract samples. The applicability of the assay was validated on the basis of EU guidelines and the detection capability was lower than or equal to 2 µg/kg, which is the EU maximum residue limit for aflatoxin B1 in cereals. False-positive and false-negative rates were less than 5%. Additionally, an open-source android application, AflaESense, was designed to provide a simple interface that displays the result in a traffic-light-type format, thus minimizing user training and time for data analysis. AflaESense was used for smartphone-based screening of spiked corn samples containing aflatoxin B1 (0.1, 2, and 10 ng/mL), and naturally contaminated corn containing 0.15 ng aflatoxin B1/mL. The measured values were in close agreement with spiked concentrations (r2 = 0.99), with recovery values ranging between 80 and 120%. Finally, contaminated samples correctly triggered a red alert while the non-contaminated samples led to the display of a green color of AflaESense. To the best of our knowledge, this is the first smartphone-based electrochemical system effective for screening samples for contamination with aflatoxin B1.

RESUMO

Substandard and falsified medicines present a serious threat to public health. Simple, low-cost screening tools are important in the identification of such products in low- and middle-income countries. In the present study, a smartphone-based imaging software was developed for the quantification of thin-layer chromatographic (TLC) analyses. A performance evaluation of this tool in the TLC analysis of 14 active pharmaceutical ingredients according to the procedures of the Global Pharma Health Fund (GPHF) Minilab was carried out, following international guidelines and assessing accuracy, repeatability, intermediate precision, specificity, linearity, range and robustness of the method. Relative standard deviations of 2.79% and 4.46% between individual measurements were observed in the assessments of repeatability and intermediate precision, respectively. Small deliberate variations of the conditions hardly affected the results. A locally producible wooden box was designed which ensures TLC photography under standardized conditions and shielding from ambient light. Photography and image analysis were carried out with a low-cost Android-based smartphone. The app allows to share TLC photos and quantification results using messaging apps, e-mail, cable or Bluetooth connections, or to upload them to a cloud. The app is available free of charge as General Public License (GPL) open-source software, and interested individuals or organizations are welcome to use and/or to further improve this software.

RESUMO

Ideally, a patient's response to medication can be monitored by measuring changes in performance of some activity. In observational studies, however, any detected association between treatment ("on-medication" vs "off-medication") and the outcome (performance in the activity) might be due to confounders. In particular, causal inferences at the personalized level are especially vulnerable to confounding effects that arise in a cyclic fashion. For quick acting medications, effects can be confounded by circadian rhythms and daily routines. Using the time-of-the-day as a surrogate for these confounders and the performance measurements as captured on a smartphone, we propose a personalized statistical approach to disentangle putative treatment and "time-of-the-day" effects, that leverages conditional independence relations spanned by causal graphical models involving the treatment, time-of-the-day, and outcome variables. Our approach is based on conditional independence tests implemented via standard and temporal linear regression models. Using synthetic data, we investigate when and how residual autocorrelation can affect the standard tests, and how time series modeling (namely, ARIMA and robust regression via HAC covariance matrix estimators) can remedy these issues. In particular, our simulations illustrate that when patients perform their activities in a paired fashion, positive autocorrelation can lead to conservative results for the standard regression approach (i.e., lead to deflated true positive detection), whereas negative autocorrelation can lead to anticonservative behavior (i.e., lead to inflated false positive detection). The adoption of time series methods, on the other hand, leads to well controlled type I error rates. We illustrate the application of our methodology with data from a Parkinson's disease mobile health study.

RESUMO

BACKGROUND: Addiction to Smartphone usage has psychological and physical impacts. However, the state of spasm of accommodation is unclear in Smartphone abusers. METHODS: We performed a cross-sectional study among adults aged 18-35 years between October 2016 and December 2018. Forty participants were Smartphone abusers according to the Smartphone addiction questionnaire, and 40 participants were non users. We measured auto refraction precycloplegia and postcycloplegia at far for all participants to evaluate the state of spasm of accommodation. We assessed the ultrasound biomicroscopy (UBM) parameters including anterior chamber angle (ACA). RESULTS: There was a significant difference in the odds of having spasm of accommodation between Smartphone abusers compared to non-users (OR = 6.64, 95% CI = 1.73-25.47; adjusted OR = 14.63, 95% CI = 2.99-71.62). The Smartphone abusers and non-users groups had a superior ACA median of 30.45° ± 8.3° vs. 26.75° ± 6.6° (P = 0.04) precycloplegia at far and 31.70° ± 11.8° vs. 31.45° ± 8.3° (P = 0.15) postcycloplegia at far, respectively, demonstrated by the Mann-Whitney U test. There was significant higher difference in the precycloplegic nasal ACA at far in the Smartphone abusers group than the non-users group (mean precycloplegic nasal ACA difference = 3.57°, 95% CI = 0.76° - 6.37°), demonstrated by the independent t test. Similarly, there was significant higher difference in the postcycloplegic nasal ACA at far (mean postcycloplegic nasal ACA difference = 4.26°, 95% CI = 1.33° - 7.19°). CONCLUSIONS: Smartphone abusers are in a condition of accommodation spasm. As a result, cycloplegic refraction should be done for Smartphone abusers.

RESUMO

BACKGROUND: Smartphone apps are increasingly used to deliver physical activity and sedentary behaviour interventions for people with cardiovascular disease. However, the active components of these interventions which aim to change behaviours are unclear. AIMS: To identify behaviour change techniques used in smartphone app interventions for improving physical activity and sedentary behaviour in people with cardiovascular disease. Secondly, to investigate the association of the identified techniques on improving these behaviours. METHODS: Six databases (Medline, CINAHL Plus, Cochrane Library, SCOPUS, Sports Discus, EMBASE) were searched from 2007 to October 2020. Eligible studies used a smartphone app intervention for people with cardiovascular disease and reported a physical activity and/or sedentary behaviour outcome. The behaviour change techniques used within the apps for physical activity and/or sedentary behaviour were coded using the Behaviour Change Technique Taxonomy (v1). The association of behaviour change techniques on physical activity outcomes were explored through meta-regression. RESULTS: Forty behaviour change techniques were identified across the 19 included app-based interventions. Only two studies reported the behaviour change techniques used to target sedentary behaviour change. The most frequently used techniques for sedentary behaviour and physical activity were habit reversal and self-monitoring of behaviour respectively. In univariable analyses, action planning (ß =0.42, 90%CrI 0.07-0.78) and graded tasks (ß =0.33, 90%CrI -0.04-0.67) each had medium positive associations with increasing physical activity. Participants in interventions that used either self-monitoring outcome(s) of behaviour (i.e. outcomes other than physical activity) (ß = - 0.47, 90%CrI -0.79--0.16), biofeedback (ß = - 0.47, 90%CrI -0.81--0.15) and information about health consequences (ß = - 0.42, 90%CrI -0.74--0.07) as behaviour change techniques, appeared to do less physical activity. In the multivariable model, these predictors were not clearly removed from zero. CONCLUSION: The behaviour change techniques action planning and graded tasks are good candidates for causal testing in future experimental smartphone app designs.

RESUMO

BACKGROUND: Social competence training interventions, especially child-focused ones, have proven to be effective in the treatment of children with conduct disorder. Therapy homework assignments implemented between the therapy sessions are essential for practicing strategies developed during treatment sessions and transferring them to everyday life. However, clinical experience shows that patients' adherence regarding these assignments is often low, thus diminishing the treatment success. One obstacle in this regard is a lack of motivation. The use of smartphone apps in the context of child and adolescent psychotherapy is relatively new, and may provide novel ways to improve the transfer of coping strategies to daily life between treatment sessions. However, only a small number of high-quality studies have analyzed the systematic use of smartphone apps in therapy. The present study will therefore evaluate patients' homework assignment adherence when using a smartphone app as compared to a paper-and-pencil method. METHOD: The study will be conducted as a randomized controlled trial to evaluate the impact of a smartphone app on the adherence to therapy homework assignments (n = 35) in the treatment of children with aggressive behavior aged 6-12 years compared to paper-and-pencil homework assignments (n = 35). DISCUSSION: This trial is intended as a pilot study and aims to provide a basis for a subsequent multicenter trial. However, the results may already lead to recommendations for the development and use of mental health-related smartphone apps for children and adolescents with aggressive behavior problems.

RESUMO

The purpose of this study was to categorize subjective perceptions of smartphone app use among mothers with young children, derive characteristics of each perception type, and interpret the findings to determine appropriate smartphone use for each perception type. We applied the Q methodology to classify and analyze the types of perceptions of mothers with young children. Ultimately, we selected 40 Q samples by comprehensively analyzing in-depth interviews with mothers of young children and conducting reviews of literature related to smartphone app use. The P samples in the study consisted of 31 mothers. We performed data analysis using the QUANL program. The analysis identified four types of smartphone users: (1) "multi-adapters" who actively utilize functions, (2) "chaos dilemma" users who understand the disadvantages of smartphones but cannot refrain from using smartphone apps, (3) "time-killer dependent" users who utilize apps to relieve temporary stress and anxiety, and (4) "self-development focused users" who pursue positive changes. Based on these findings, we suggest ways in which mothers of young children can utilize smartphone apps in a developmental and appropriate manner.

RESUMO

Based on problem behavior theory and interpersonal acceptance-rejection theory, this study aimed to examine the mediating roles of self-esteem and fear of missing out (FoMO) on the influence of parental support on adolescents' problematic smartphone use. This study is a cross-sectional and descriptive study. A total of 260 Korean adolescents from two public middle schools were selected through convenience sampling (female, 50.4%; mean age, 13.16 ± 0.84; range age, 12~15). Participants completed self-report questionnaires assessing sociodemographic characteristics, parental support, self-esteem, FoMO, and problematic smartphone use. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and mediation analysis. The findings show that self-esteem and FoMO play a serial mediating role in the relationship between parental support and adolescents' problematic smartphone use. Specifically, parental support had a negative effect on adolescents' problematic smartphone use by increasing self-esteem but decreasing FoMO. These results provide further guidance in the prevention of and intervention of adolescent problematic smartphone use.

RESUMO

During the last several years, the Internet of Things (IoT), fog computing, computer security, and cyber-attacks have all grown rapidly on a large scale. Examples of IoT include mobile devices such as tablets and smartphones. Attacks can take place that impact the confidentiality, integrity, and availability (CIA) of the information. One attack that occurs is Advanced Persistent Threat (APT). Attackers can manipulate a device's behavior, applications, and services. Such manipulations lead to signification of a deviation from a known behavioral baseline for smartphones. In this study, the authors present a Systematic Literature Review (SLR) to provide a survey of the existing literature on APT defense mechanisms, find research gaps, and recommend future directions. The scope of this SLR covers a detailed analysis of most cybersecurity defense mechanisms and cutting-edge solutions. In this research, 112 papers published from 2011 until 2022 were analyzed. This review has explored different approaches used in cybersecurity and their effectiveness in defending against APT attacks. In a conclusion, we recommended a Situational Awareness (SA) model known as Observe-Orient-Decide-Act (OODA) to provide a comprehensive solution to monitor the device's behavior for APT mitigation.

RESUMO

In this study, we developed a range of motion sensing system (ROMSS) to simulate the function of the elbow joint, with errors less than 0.76 degrees and 0.87 degrees in static and dynamic verification by the swinging and angle recognition modules, respectively. In the simulation process, the É£ correlation coefficient of the Pearson difference between the ROMSS and the universal goniometer was 0.90, the standard deviations of the general goniometer measurements were between ±2 degrees and ±2.6 degrees, and the standard deviations between the ROMSS measurements were between ±0.5 degrees and ±1.6 degrees. With the ROMSS, a cloud database was also established; the data measured by the sensor could be uploaded to the cloud database in real-time to provide timely patient information for healthcare professionals. We also developed a mobile app for smartphones to enable patients and healthcare providers to easily trace the data in real-time. Historical data sets with joint activity angles could be retrieved to observe the progress or effectiveness of disease recovery so the quality of care could be properly assessed and maintained.
