RESUMO

ABSTRACT Objective: to describe Covid-19 mobile applications available for download on smartphones. Method: a cross-sectional study with 52 mobile applications on Covid-19, obtained from virtual stores for smartphones with Android and iOS operating systems. Fisher's exact test and Cramér's V were used. Results: of the applications, 45 (86.6%) were developed in 2020, 51 (98.1%) were free, and 49 (94.2%) did not have accessibility for people with disabilities. It was observed that, in 23 countries, 17 (32.7%) applications in English and 14 (26.9%) in Portuguese were created, with a choice of 11 languages, relating to nine subthemes on Covid-19, the majority on "case monitoring" and "symptoms, prevention, and care", with 17 (32.7%) each. There was an association between the target audience and the subtheme of "symptoms, prevention, and care", and between patient monitoring and professional training. Conclusion: Covid-19 mobile applications were available in countries on five continents, in the main languages of communication and free of charge; however, with limited accessibility for people with disabilities.

RESUMO

BACKGROUND AND STUDY OBJECTIVE: The COVID-19 pandemic has forced assisted living facilities (ALF) to implement strict social isolation for residents. Social isolation in the geriatric population is known to negatively impact health. Here, we describe how ALFs in Rhode Island utilized device donations received from Connect for COVID-19, a nationwide nonprofit organization which has mobilized medical students to gather devices for donations to care centers. METHODS: Rhode Island ALFs were contacted to determine if they were interested in receiving smart device donations. After donations were made, an impact survey was electronically administered. Primary Results: A total of 11 facilities completed the survey with a response rate of 24% (11/46). The facilities were located throughout all five counties in Rhode Island, with the majority located in Providence County. All but one of the facilities that responded to the survey (n=10, 90.9%) have used the devices to allow residents to video-call their family members. Seven responses (63.6%) indicated that devices were used for more than one purpose. Primary Conclusions: Smart devices were well received by Rhode Island ALFs and used for purposes beyond video conference calls. ALFs should consider advertising the need for devices to encourage community donations. Future studies should investigate the direct impact that digital connectivity has had on Rhode Island ALF residents.

RESUMO

INTRODUCTION: In response to the coronavirus disease 2019 (COVID-19) pandemic, New York City closed all nonessential businesses and restricted the out-of-home activities of residents as of March 22, 2020. This order affected different neighborhoods differently, as stores and workplaces are not randomly distributed across the city, and different populations may have responded differently to the out-of-home restrictions. This study examines how the business closures and activity restrictions affected COVID-19 testing results. An evaluation of whether such actions slowed the spread of the pandemic is a crucial step in designing effective public health policies. METHODS: Daily data on the fraction of COVID-19 tests yielding a positive result at the zip code level were analyzed in relation to the number of visits to local businesses (based on smartphone location) and the number of smartphones that stayed fixed at their home location. The regression model also included vectors of fixed effects for the day of the week, the calendar date, and the zip code of residence. RESULTS: A large number of visits to local businesses increased the positivity rate of COVID-19 tests, while a large number of smartphones that stayed at home decreased it. A doubling in the relative number of visits increases the positivity rate by about 12.4 percentage points (95% CI, 5.3 to 19.6). A doubling in the relative number of stay-at-home devices lowered it by 2.0 percentage points (95% CI, -2.9 to -1.2). The business closures and out-of-home activity restrictions decreased the positivity rate, accounting for approximately 25% of the decline observed in April and May 2020. CONCLUSION: Policy measures decreased the likelihood of positive results in COVID-19 tests. These specific policy tools may be successfully used when comparable health crises arise in the future.

RESUMO

The COVID-19 pandemic provides an urgent example where a gap exists between availability of state-of-the-art diagnostics and current needs. As assay protocols and primer sequences become widely known, many laboratories perform diagnostic tests using methods such as RT-PCR or reverse transcription loop mediated isothermal amplification (RT-LAMP). Here, we report an RT-LAMP isothermal assay for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus and demonstrate the assay on clinical samples using a simple and accessible point-of-care (POC) instrument. We characterized the assay by dipping swabs into synthetic nasal fluid spiked with the virus, moving the swab to viral transport medium (VTM), and sampling a volume of the VTM to perform the RT-LAMP assay without an RNA extraction kit. The assay has a limit of detection (LOD) of 50 RNA copies per µL in the VTM solution within 30 min. We further demonstrate our assay by detecting SARS-CoV-2 viruses from 20 clinical samples. Finally, we demonstrate a portable and real-time POC device to detect SARS-CoV-2 from VTM samples using an additively manufactured three-dimensional cartridge and a smartphone-based reader. The POC system was tested using 10 clinical samples, and was able to detect SARS-CoV-2 from these clinical samples by distinguishing positive samples from negative samples after 30 min. The POC tests are in complete agreement with RT-PCR controls. This work demonstrates an alternative pathway for SARS-CoV-2 diagnostics that does not require conventional laboratory infrastructure, in settings where diagnosis is required at the point of sample collection.

RESUMO

To describe a smartphone-based telemedicine tool for monitoring of corneal ulcer size during the corona pandemic, a simple "U"-shaped tool was constructed using three Schirmer's strips that were provided to the patients with small to medium-sized corneal ulcers. The patient and the attendant were trained to use this simple U-shaped tool at home and send digital images to the treating ophthalmologist, to monitor the course of the ulcer. The tool was used in five eyes of five patients with active microbial keratitis. Patients were followed up regularly with the use of telemedicine facility every 48 h for an average duration of 7.6 days (range 6-9 days). In all the five eyes, assessment of the serial images with U-shaped tool showed decrease in size of corneal ulcer, which corroborated with subjective improvement in symptoms. Hence, the novel "'U'-shaped tool" may provide an effective measure in following-up of corneal ulcer patients in times of the COVID-19 pandemic, obviating frequent hospital visits and risk of contracting COVID.

RESUMO

Online and distance education may be dismissed by educators who argue that these methods are not equivalent to traditional face-to-face education due to the lack of laboratory classes. However, smartphone-assisted experimentation is an innovative and powerful didactic tool that helps educators in the teaching process of physiology, particularly in situations with a lack of financial support for purchasing laboratory equipment, or lack of support for homework and assignments, distance learning courses, and emergency remote education, such as during the COVID-19 pandemic. Therefore, we present the concept of the mobile learning laboratory (MobLeLab), which is a collection of smartphone applications that allow scientific data collection, such as physiological variables, for educational purposes. The three types of MobLeLabs (simulators, built-in, and plug-in) are presented, as well as ideas on how to use smartphone sensors to collect physiological data. Additionally, we elaborate on the principles of the protocols for physiology education with MobLeLabs and discuss their importance to fostering scientific method reasoning by students.

RESUMO

The popularization of smart technology is a global phenomenon. The increasing ubiquity of smartphones offers the potential to apply smart technology in areas such as healthcare and behavioral change interventions. Mobile health services may enhance the effectiveness and resolve the shortcomings of traditional medical services, which cannot continuously and instantly track changes in disease symptoms. The popularity of mobile phones has led to the emergence of mobile health applications. Mobile health applications use active and passive methods to collect data and transmit information. Studies have confirmed the feasibility and acceptance of these applications in assessing and detecting diseases and in mental health interventions. In this article, the limitations of traditional psychiatric medical diagnosis and the opportunity to develop mobile health using information and communication technology are discussed, and related empirical research on using smart technology to evaluate and detect symptoms is explored using the example of bipolar disorders. In addition, the benefits and future prospects of onset alert and the development of healthcare models for action are highlighted. In the future, we look forward to developing mobile health applications that meet the needs of healthcare in Taiwan. Furthermore, we recommend more research and investment in related fields to accumulate more extensive empirical evidence.

RESUMO

BACKGROUND: In the absence of a vaccine or effective treatment for COVID-19, countries have adopted nonpharmaceutical interventions (NPIs) such as social distancing and full lockdown. An objective and quantitative means of passively monitoring the impact and response of these interventions at a local level is needed. OBJECTIVE: We aim to explore the utility of the recently developed open-source mobile health platform Remote Assessment of Disease and Relapse (RADAR)-base as a toolbox to rapidly test the effect and response to NPIs intended to limit the spread of COVID-19. METHODS: We analyzed data extracted from smartphone and wearable devices, and managed by the RADAR-base from 1062 participants recruited in Italy, Spain, Denmark, the United Kingdom, and the Netherlands. We derived nine features on a daily basis including time spent at home, maximum distance travelled from home, the maximum number of Bluetooth-enabled nearby devices (as a proxy for physical distancing), step count, average heart rate, sleep duration, bedtime, phone unlock duration, and social app use duration. We performed Kruskal-Wallis tests followed by post hoc Dunn tests to assess differences in these features among baseline, prelockdown, and during lockdown periods. We also studied behavioral differences by age, gender, BMI, and educational background. RESULTS: We were able to quantify expected changes in time spent at home, distance travelled, and the number of nearby Bluetooth-enabled devices between prelockdown and during lockdown periods (P<.001 for all five countries). We saw reduced sociality as measured through mobility features and increased virtual sociality through phone use. People were more active on their phones (P<.001 for Italy, Spain, and the United Kingdom), spending more time using social media apps (P<.001 for Italy, Spain, the United Kingdom, and the Netherlands), particularly around major news events. Furthermore, participants had a lower heart rate (P<.001 for Italy and Spain; P=.02 for Denmark), went to bed later (P<.001 for Italy, Spain, the United Kingdom, and the Netherlands), and slept more (P<.001 for Italy, Spain, and the United Kingdom). We also found that young people had longer homestay than older people during the lockdown and fewer daily steps. Although there was no significant difference between the high and low BMI groups in time spent at home, the low BMI group walked more. CONCLUSIONS: RADAR-base, a freely deployable data collection platform leveraging data from wearables and mobile technologies, can be used to rapidly quantify and provide a holistic view of behavioral changes in response to public health interventions as a result of infectious outbreaks such as COVID-19. RADAR-base may be a viable approach to implementing an early warning system for passively assessing the local compliance to interventions in epidemics and pandemics, and could help countries ease out of lockdown.

RESUMO

Operation Outbreak (OO) is a Bluetooth-based simulation platform that teaches students how pathogens spread and the impact of interventions, thereby facilitating the safe reopening of schools. OO also generates data to inform epidemiological models and prevent future outbreaks. Before SARS-CoV-2 was reported, we repeatedly simulated a virus with similar features, correctly predicting many human behaviors later observed during the pandemic.

RESUMO

Eye tracking has been widely used for decades in vision research, language and usability. However, most prior research has focused on large desktop displays using specialized eye trackers that are expensive and cannot scale. Little is known about eye movement behavior on phones, despite their pervasiveness and large amount of time spent. We leverage machine learning to demonstrate accurate smartphone-based eye tracking without any additional hardware. We show that the accuracy of our method is comparable to state-of-the-art mobile eye trackers that are 100x more expensive. Using data from over 100 opted-in users, we replicate key findings from previous eye movement research on oculomotor tasks and saliency analyses during natural image viewing. In addition, we demonstrate the utility of smartphone-based gaze for detecting reading comprehension difficulty. Our results show the potential for scaling eye movement research by orders-of-magnitude to thousands of participants (with explicit consent), enabling advances in vision research, accessibility and healthcare.

RESUMO

BACKGROUND: The COVID-19 pandemic has recently spread dramatically worldwide, raising considerable concerns and resulting in detrimental effects on the psychological health of people who are vulnerable to the disease. Therefore, assessment of depression in members of the general public and their psychological and behavioral responses is essential for the maintenance of health. OBJECTIVE: This study aimed to assess the prevalence of depression and the associated factors among the general public during the early stages of the COVID-19 pandemic in China. METHODS: A cross-sectional survey with convenience sampling was conducted from February 11 to 16, 2020, in the early stages of the COVID-19 outbreak in China. A self-administrated smartphone questionnaire based on the Patient Health Questionnaire-9 (PHQ-9) and psychological and behavioral responses was distributed to the general public. Hierarchical multiple regression analysis and multivariate logistic regression analysis were conducted to explore the associated factors of depression.aA cross-sectional survey with convenience sampling was conducted from February 11 to 16, 2020, in the early stages of the COVID-19 outbreak in China. A self-administrated smartphone questionnaire based on the Patient Health Questionnaire-9 (PHQ-9) and psychological and behavioral responses was distributed to the general public. Hierarchical multiple regression analysis and multivariate logistic regression analysis were conducted to explore the associated factors of depression. RESULTS: The prevalence of depression (PHQ-9 score ≥10) among the general public during the COVID-19 pandemic was 182/1342 (13.6%). Regression analysis indicated that feeling stressed, feeling helpless, persistently being worried even with support, never feeling clean after disinfecting, scrubbing hands and items repeatedly, hoarding food, medicine, or daily supplies, and being distracted from work or study were positively associated with depression, while social support and being calm were negatively associated with depression. CONCLUSIONS: The general public suffered from high levels of depression during the early stages of the COVID-19 pandemic. Thus, COVID-19-related mood management and social support should be provided to attenuate depression in the general public.

RESUMO

Social distancing and contact/exposure tracing are accepted to be critical strategies in the fight against the COVID-19 epidemic. They are both closely connected to the ability to reliably establish the degree of proximity between people in real-world environments. We proposed, implemented, and evaluated a wearable proximity sensing system based on an oscillating magnetic field that overcomes many of the weaknesses of the current state of the art Bluetooth based proximity detection. In this paper, we first described the underlying physical principle, proposed a protocol for the identification and coordination of the transmitter (which is compatible with the current smartphone-based exposure tracing protocols). Subsequently, the system architecture and implementation were described, finally an elaborate characterization and evaluation of the performance (both in systematic lab experiments and in real-world settings) were performed. Our work demonstrated that the proposed system is much more reliable than the widely-used Bluetooth-based approach, particularly when it comes to distinguishing between distances above and below the 2.0 m threshold due to the magnetic field's physical properties.

RESUMO

There are various health benefits of regular physical activity (PA) and health risks of sedentariness. The Covid-19 pandemic may have decreased PA and increased sedentariness for several reasons (e.g., closure of gyms, family-related time constraints, and reduced outdoor mobility). Yet, to date, there are no longitudinal studies that examined whether the pandemic affects PA levels and what factors help people remain physically active during lockdown. This study aims to investigate changes in U.S. residents' PA during (vs. before) the Covid-19 pandemic and predictors of changes, with a focus on PA smartphone applications (apps) and their features (i.e., motivational, educational, or gamification related). The study utilized a two-wave longitudinal survey design with an online panel. Healthy adults (N = 431) from 45 U.S. states self-reported their PA levels before and during lockdown. PA app use and app feature ratings were assessed. t-tests and regression analyses were conducted. Moderate PA, vigorous PA, and PA measured in metabolic equivalent of task (MET) minutes per week decreased during lockdown (all p < .01). Controlling for PA before lockdown and individuals' PA intentions, PA app use was positively related to overall change in PA, measured in MET minutes per week (ß = 15.68, standard error = 7.84, p < .05). PA decreased less with increasing app use frequency. When app features were added to the model, a buffering effect for gamification features was identified. The Covid-19-caused lockdown decreased U.S. residents' PA levels by 18.2%. The use of PA apps may help buffer the decline, and gamification-related app features may be particularly helpful in this context.

RESUMO

BACKGROUND The efficacy of telemedicine in reducing delay times and short-term adverse clinical outcomes in patients with ST segment elevation myocardial infarction (STEMI) during the coronavirus disease 2019 (COVID-19) pandemic is unclear. This study compared outcomes in patients with STEMI who had percutaneous coronary intervention (PCI) and the use of a telemedicine app from August 2019 to March 2020 at a single center in Beijing, China. MATERIAL AND METHODS A total of 243 patients with STEMI who underwent PCI were consecutively enrolled and divided into 2 groups according to the date, before or after the pandemic. The 2 groups were further divided into patients who used the app for consulting and those who did not. RESULTS The time from symptom onset to calling an ambulance (SCT), door to balloon time (DTB), and total ischemia time (TIT) were significantly prolonged in patients after the pandemic. Patients who used the app had shorter SCT, DTB, and TIT before and after the pandemic compared to those who did not. Adverse clinical outcomes were significantly higher after compared with before the pandemic, despite the incidence rate of stroke, any revascularization, and stent thrombosis. However, there was no significant difference in short-term adverse clinical outcomes between patients who used the app and those who did not before and after the pandemic. CONCLUSIONS Telemedicine reduced the delay time of STEMI patients during the COVID-19 pandemic. The difference in short-term adverse clinical outcomes was not statistically significant between patients who used the app and those who did not.

RESUMO

The outbreaks of the infectious disease COVID-19 caused by SARS-CoV-2 seriously threatened the life of humans. A rapid, reliable and specific detection method was urgently needed. Herein, we reported a contamination-free visual detection method for SARS-CoV-2 with LAMP and CRISPR/Cas12a technology. CRISPR/Cas12a reagents were pre-added on the inner wall of the tube lid. After LAMP reaction, CRISPR/Cas12a reagents were flowed into the tube and mixed with amplicon solution by hand shaking, which can effectively avoid possible amplicon formed aerosol contamination caused by re-opening the lid after amplification. CRISPR/Cas12a can highly specific recognize target sequence and discriminately cleave single strand DNA probes (5'-6FAM 3'-BHQ1). With smart phone and portable 3D printing instrument, the produced fluorescence can be seen by naked eyes without any dedicated instruments, which is promising in the point-of-care detection. The whole amplification and detection process could be completed within 40 min with high sensitivity of 20 copies RNA of SARS-CoV-2. This reaction had high specificity and could avoid cross-reactivity with other common viruses such as influenza virus. For 7 positive and 3 negative respiratory swab samples provided by Zhejiang Provincial Center for Disease Control and Prevention, our detection results had 100% positive agreement and 100% negative agreement, which demonstrated the accuracy and application prospect of this method.

RESUMO

Background: Smartphones has significantly changed the lifestyle of people and considered as basic need for day to day work. But its usages beyond certain limits adversely affects physical and mental health. Aim of this study is to analyzes the quantitative usages of smartphone among controlled and uncontrolled type 2 diabetes patients. Objective is to correlate the pattern and duration of smartphone usages with the level of glycemic control. Method: "RealizD" is a mobile application that observes the pattern of mobile phone usages like 'screen time' (total duration of time spends watching mobile screen for any purpose) and number of times phone picked in a day. It graphically displays the hourly usages and longest duration of phone use in a single stretch. Subjects were patients of type 2 diabetes mellitus(T2DM) divided into 50 "case" with poor glycemic control and 50 "control" with good glycemic control. This application was installed in their smartphones to collect all above data. Subjects were observed for period of 3 months. Demographic data, blood glucose levels and HbA1c was recorded at first and again at second visit 3 months after. Data from application was recorded at second visit as described above. Findings: The average screen time of cases was 160 ± 50.9 minutes per day whereas of controls was 107 ± 22.5 minutes. This difference in the screen time was statistically significant. Higher the screen time more was the HbA1c. The average of number of times a case picked his/her phone in a day was 70.2 ± 20.1 whereas by the controls was 57.3 ± 22.2. The difference was statistically significant. Also, Cases spend 37.3 % versus controls who spend 19.9 % of total screen time between 5 AM to 9 AM. The difference was statistically significant. This indicates that uncontrolled T2DM patients spend more time on phone in morning hours. Interpretation: Smartphones could be best companion if used judiciously. Their unrestricted use adversely affects the health. Among diabetes patient unregulated smartphone usages leads to poor glycemic control and thus could be considered an important factor that need to be addressed.

RESUMO

The global impact of COVID-19 pandemic has led to a rapid development and utilization of mobile health applications. These are addressing the unmet needs of healthcare and public health system including contact tracing, health information dissemination, symptom checking and providing tools for training healthcare providers. Here we provide an overview of mobile applications being currently utilized for COVID-19 and their assessment using the Mobile Application Rating Scale. We performed a systematic review of the literature and mobile platforms to assess mobile applications currently utilized for COVID-19, and a quality assessment of these applications using the Mobile Application Rating Scale (MARS) for overall quality, Engagement, Functionality, Aesthetics, and Information. Finally, we provide an overview of the key salient features that should be included in mobile applications being developed for future use. Our search identified 63 apps that are currently being used for COVID-19. Of these, 25 were selected from the Google play store and Apple App store in India, and 19 each from the UK and US. 18 apps were developed for sharing up to date information on COVID-19, and 8 were used for contact tracing while 9 apps showed features of both. On MARS Scale, overall scores ranged from 2.4 to 4.8 with apps scoring high in areas of functionality and lower in Engagement. Future steps should involve developing and testing of mobile applications using assessment tools like the MARS scale and the study of their impact on health behaviours and outcomes.
