Published: February 2022

Air Conditioners (AC) are increasingly used to get the room temperature as desired, starting from home use to keep the room cool and enjoyable, to specific room like server rooms or ATM which are focused on keeping the room cool in order to keep the equipment cool. The role of AC is quite important to maintain room temperature, and its increasing use has led to the growing need for users to control the AC. The Internet of Things allows users to remotely control air conditioners using the gadgets used and get real time room temperature information. The AC control system based on Internet of Things (IoT) utilizes an internet connection to monitor room temperature and control AC remotely. The devices used are DHT11 as a temperature sensor to get room temperature, Infrared Receiver to read the code sent by the remote AC, Infrared Transmitter to send commands to the AC in the room, and ESP8266 as a microcontroller and a link to the internet. The IoT platform used is Blynk which has the ability to access the microcontroller from the user's gadget. The tests are running on room air conditioners such as the Panasonic CS-PC18PKP series, the Panasonic CS-YN18TKP series and the Samsung AR09TGHQASINSE series. The test results showed that the room air conditioner was successfully controlled, and the room temperature was read in real time via an android smartphone.

Socio-Cultural Adaptation and Integration of Migrants as Tool of State Migration Policy in Soviet Period
Authors: Bazhan T. A.
Published: February 2022

Russian migration policy is facing a number of problems, whose effective solution has not been found yet. They include the absence of infrastructure for social and cultural adaptation and integration of migrants and high level of illegal migration. The system of organized drawing-in workers-migrants has not been developed. To resolve these problems it would be useful to analyze the experience of the soviet period, when complicated migration problems were successfully settled. A system of steps aimed at assisting socio-cultural adaptation and integration of internal migrants was promoted by involvement of the population in their solution. The present article analyzes specific features and mechanisms of state migration policy of the soviet period, which supported the needs of economy in labour, helped populate the remote areas of the country and create conditions for the development of human capital. State policy in this sphere was planned and successive: it staked at internal labour migration; migration flows were regulated; state was interested in the development of industrial, agricultural and cultural potential of territories, where migrants arrived. Critical study of the experience of migrants’ adaptation and integration in this period, identifying mechanisms, which can work in current conditions would allow us to optimize today’s migration policy and practice of its pursuing.

Особенности полиморфного превращения при нагреве и охлаждении кобальта
Authors: Спивак Л.В. , Щепина Н.Е.
Published: February 2022

Differential scanning calorimetry was used to study the regularities of polymorphic αβ transformation in polycrystalline cobalt. The value of the activation energy of the αβ transformation during heating of cobalt (29050 kJ/mol), enthalpy and entropy, depending on the thermal history of the metal, is determined. It is shown that the mechanisms of recrystallization under heating are closer to the first-order I phase transformations. When cooling under conditions of limited diffusion mobility of cobalt atoms, recrystallization is apparently carried out due to the passage of several diffusion-free mechanisms of phase transformation, implemented in close temperature ranges.

Published: February 2022

UNSTRUCTURED

The use of telemedicine has increased dramatically through the COVID-19 pandemic. While data is available about patient satisfaction with healthcare through telemedicine, little is known about the immigrant patient experience. We hypothesized that immigrant patients would prefer live visits as well as have higher ratings for interpersonal communication during live visits over telemedicine. We also expected that other satisfaction category ratings would be similar between immigrant and nonimmigrant patients.
Patients seen by four Internal Medicine providers in both a live and telemedicine setting were surveyed. Patients seen via live visits were given a paper copy of the survey at the beginning of the visit and the same survey was administered by follow-up phone call for telemedicine visits. Surveys were administered in English, Spanish or Arabic. The survey consisted of 9 questions on a satisfaction scale of 1-5 assessing satisfaction under the categories of access to care, interpersonal interaction, quality of care and next visit preference. An additional question assessed reasons for next visit type preferences.
Survey data were collected from 115 televisits and 108 live visits. These responses came from 60 immigrant and 163 non-immigrant patients. Across both patient populations, satisfaction with access to care, interpersonal interaction, and quality of care was universally high with no significant difference between patient groups. More common reasons for non-immigrants to prefer televisits included convenience. Immigrant patients more often prioritized time with the provider, some citing an advantage of not having to navigate the office and feeling as though they had the provider's undivided attention. Patients in both groups who preferred live visits cited visit quality as a driving factor of visit type selection.
While satisfaction was equally high for both telemedicine and live visits across immigrant and non-immigrant populations, differences in patient satisfaction priorities arose and may suggest opportunities to minimize health equity barriers.
Noninvasive Diagnosis of Nonalcoholic Steatohepatitis and Advanced Liver Fibrosis Using Machine Learning Methods: Comparative Study With Existing Quantitative Risk Scores (Preprint)
Authors: Wu Yonghui , Yang Xi , Morris Heather L , Gurka Matthew J , Shenkman Elizabeth A , Cusi Kenneth , Bril Fernando , Donahoo William T
Published: February 2022

BACKGROUND

Nonalcoholic steatohepatitis (NASH), advanced fibrosis, and subsequent cirrhosis and hepatocellular carcinoma are becoming the most common etiology for liver failure and liver transplantation; however, they can only be diagnosed at these potentially reversible stages with a liver biopsy, which is associated with various complications and high expenses. Knowing the difference between the more benign isolated steatosis and the more severe NASH and cirrhosis informs the physician regarding the need for more aggressive management.

OBJECTIVE

We intend to explore the feasibility of using machine learning methods for noninvasive diagnosis of NASH and advanced liver fibrosis and compare machine learning methods with existing quantitative risk scores.

METHODS

We conducted a retrospective analysis of clinical data from a cohort of 492 patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD), NASH, or advanced fibrosis. We systematically compared 5 widely used machine learning algorithms for the prediction of NAFLD, NASH, and fibrosis using 2 variable encoding strategies. Then, we compared the machine learning methods with 3 existing quantitative scores and identified the important features for prediction using the SHapley Additive exPlanations method.

RESULTS

The best machine learning method, gradient boosting (GB), achieved the best area under the curve scores of 0.9043, 0.8166, and 0.8360 for NAFLD, NASH, and advanced fibrosis, respectively. GB also outperformed 3 existing risk scores for fibrosis. Among the variables, alanine aminotransferase (ALT), triglyceride (TG), and BMI were the important risk factors for the prediction of NAFLD, whereas aspartate transaminase (AST), ALT, and TG were the important variables for the prediction of NASH, and AST, hyperglycemia (A1c), and high-density lipoprotein were the important variables for predicting advanced fibrosis.

CONCLUSIONS

It is feasible to use machine learning methods for predicting NAFLD, NASH, and advanced fibrosis using routine clinical data, which potentially can be used to better identify patients who still need liver biopsy. Additionally, understanding the relative importance and differences in predictors could lead to improved understanding of the disease process as well as support for identifying novel treatment options.
Exploring COVID-19–Related Stressors: Topic Modeling Study (Preprint)
Authors: Leung Yue Tong , Khalvati Farzad
Published: February 2022

BACKGROUND

The COVID-19 pandemic has affected the lives of people globally for over 2 years. Changes in lifestyles due to the pandemic may cause psychosocial stressors for individuals and could lead to mental health problems. To provide high-quality mental health support, health care organizations need to identify COVID-19–specific stressors and monitor the trends in the prevalence of those stressors.

OBJECTIVE

This study aims to apply natural language processing (NLP) techniques to social media data to identify the psychosocial stressors during the COVID-19 pandemic and to analyze the trend in the prevalence of these stressors at different stages of the pandemic.

METHODS

We obtained a data set of 9266 Reddit posts from the subreddit \rCOVID19_support, from February 14, 2020, to July 19, 2021. We used the latent Dirichlet allocation (LDA) topic model to identify the topics that were mentioned on the subreddit and analyzed the trends in the prevalence of the topics. Lexicons were created for each of the topics and were used to identify the topics of each post. The prevalences of topics identified by the LDA and lexicon approaches were compared.

RESULTS

The LDA model identified 6 topics from the data set: (1) “fear of coronavirus,” (2) “problems related to social relationships,” (3) “mental health symptoms,” (4) “family problems,” (5) “educational and occupational problems,” and (6) “uncertainty on the development of pandemic.” According to the results, there was a significant decline in the number of posts about the “fear of coronavirus” after vaccine distribution started. This suggests that the distribution of vaccines may have reduced the perceived risks of coronavirus. The prevalence of discussions on the uncertainty about the pandemic did not decline with the increase in the vaccinated population. In April 2021, when the Delta variant became prevalent in the United States, there was a significant increase in the number of posts about the uncertainty of pandemic development but no obvious effects on the topic of fear of the coronavirus.

CONCLUSIONS

We created a dashboard to visualize the trend in the prevalence of topics about COVID-19–related stressors being discussed on a social media platform (Reddit). Our results provide insights into the prevalence of pandemic-related stressors during different stages of the COVID-19 pandemic. The NLP techniques leveraged in this study could also be applied to analyze event-specific stressors in the future.
Randomized controlled trials of artificial intelligence in clinical practice: A systematic review (Preprint)
Authors: Lam Thomas YT , Cheung Max FK , Munro Yasmin L , Lim Kong Meng , Shung Dennis , Sung Joseph JY
Published: February 2022

BACKGROUND

The number of artificial intelligence (AI) studies in medicine has exponentially increased recently. However, there is no clear quantification of clinical benefit when AI-assisted tools are implemented in patient care.

OBJECTIVE

We aim to systematically review all published randomized controlled trials (RCTs) of AI-assisted tools to characterize their performance in clinical practice.

METHODS

CINAHL, Cochrane Central, Embase, Medline and PubMed were searched to identify relevant RCTs comparing the performance of AI-assisted tool against conventional clinical management without AI-assistance published up to July 2021. We evaluated the primary endpoints of each study to determine which were clinically relevant.

RESULTS

Among 11,839 articles searched, only 38 RCTs identified were included. These RCTs were conducted in a roughly equal distribution from North America, Europe, and Asia. AI-assisted tools were implemented in 13 different clinical specialties. Most RCTs were published in the field of Gastroenterology, with 15 studies on AI-assisted endoscopy. The majority of RCTs studied image-based AI-assisted tools, and a minority of RCTs studied AI-assisted tools that drew from tabular patient. In 29 out of 38 RCTs, AI-assisted interventions outperformed usual clinical care, and clinically relevant outcomes improved with AI assisted intervention in 21 out of 29 studies. Small sample size and single-centre design limit the generalizability of these studies.

CONCLUSIONS

There is growing evidence supporting the implementation of AI-assisted tool in daily clinical practice, yet the number of available RCTs is limited and heterogeneous. Future studies are needed to quantify the benefit of AI-assisted tools in clinical practice.

CLINICALTRIAL

This study was registered on PROSPERO (ID: CRD42021286539).
The Impact of Perioperative Remote Patient Monitoring on Clinical Staff Workflows: Scoping Review (Preprint)
Authors: León Maria Alejandra , Pannunzio Valeria , Kleinsmann Maaike
Published: February 2022

BACKGROUND

Remote patient monitoring (RPM) interventions are being increasingly implemented in health care environments, given their benefits for different stakeholders. However, the effects of these interventions on the workflow of clinical staff are not always considered in RPM research and practice.

OBJECTIVE

This review explored how contemporary RPM interventions affect clinical staff and their workflows in perioperative settings.

METHODS

We conducted a scoping review of recent articles reporting the impact of RPM interventions implemented in perioperative settings on clinical staff and their workflow. The databases accessed were Embase and PubMed. A qualitative analysis was performed to identify the main problems and advantages that RPM brings to staff, in addition to the approaches taken to evaluate the impact of those interventions. Different themes were identified in terms of the challenges of RPM for clinical staff as well as in terms of benefits, risk-reduction strategies, and methods for measuring the impact of these interventions on the workflow of clinical staff.

RESULTS

A total of 1063 papers were found during the initial search, of which 21 (1.98%) met the inclusion criteria. Of the 21 included papers, 15 (71%) focused on evaluating new RPM systems, 4 (19%) focused on existing systems, and 2 (10%) were reviews.

CONCLUSIONS

The reviewed literature shows that the impact on staff work experience is a crucial factor to consider when developing and implementing RPM interventions in perioperative settings. However, we noticed both underdevelopment and lack of standardization in the methods for assessing the impact of these interventions on clinical staff and their workflow. On the basis of the reviewed literature, we recommend the development of more robust methods for evaluating the impact of RPM interventions on staff experience in perioperative care; the adoption of a stronger focus on transition management when introducing these interventions in clinical practice; and the inclusion of longer periods of assessment, including the evaluation of long-term goals.

BACKGROUND

Health disparities are generally worse for New York City (NYC) public housing residents compared to the rest of the population. Extensive research has proven mobile Health (mHealth) interventions effective for improving health outcomes, including among low socioeconomic status and diverse populations. However, little research is available about the use of smartphones specifically among older adult, public housing residents.

OBJECTIVE

The objective of this study, conducted from 2017-2018, was to assess how minority and bilingual NYC public housing residents 50 years and older access and use mobile technology.

METHODS

Anonymous cross-sectional surveys (N=184) were administered to long-term, NYC public housing residents (50 years and older). Socio-demographic questions (e.g., age, gender, income, language), and a brief survey assessing technology use and access were included. Smartphone ownership, internet access, frequency of app use, and app use were evaluated.

RESULTS

Among smartphone users (N=139), 69.1% reported having an unlimited internet/data plan; 75% reported using smartphone apps “sometimes/often”. Participants also reported on their app usage. Texting was most used (91.1%), followed by music (76.4%) and email (75.6%). Racial/ethnic differences in app use were not statistically significant.

CONCLUSIONS

This study contributes to the literature on smartphone use and app use among older adult, public housing residents and suggests in app use. Researchers and practitioners should consider promoting and developing interventions for populations of low-income adults over 50 years that include text and email applications.

Authors: Bliūdžius Antanas , Švaikevičienė Kristina , Kasiulevičius Vytautas
Published: February 2022

BACKGROUND

Prediabetes is one of the most rapidly growing health problems, and the leading cause is overweight. This condition is reversible, but lifestyle-changing measures should be taken. Physical activity evaluation with consumer wearables and questionnaires is essential in family doctors’ work to help patients increase physical activity and weight control.

OBJECTIVE

This article explores the use of Fitbit activity trackers and IPAQ to assess physical activity for diabetes prevention.

METHODS

Prospective cohort pilot study. Randomly selected 30 patients (9 males and 21 females), aged 32-65 years, with impaired glucose levels and without diabetes or moving disorders. Subjects received Fitbit Inspire activity trackers, physical activity recommendations. In the first visit, patients answered IPAQ, the routine blood check was taken, and we analyzed body composition with X-contact 356 analyzer. The second visit was after six months, and we repeated the first visit procedures and extracted data from Fitbit accounts.

RESULTS

The median weight was 87.6 +- 16.9Kg and BMI 32.0 [26.4–34.6]. The count of steps per day and variability was different between patients and during the research period, but we found statistically significant improvement in body composition for all the groups. A significant decrease in weight (-1.5Kg) (P=0.022) and a mass of body fat (-1.8Kg) (P<0.001) was observed. Also, visceral fat level, visceral area, waist to hip ratio, and abdominal circumference decreased (P<0.001). IPAQ showed the change of physical activity respectively, and the self-reported physical activity correlated with Fitbit data. Though the questionnaire reported active minutes was significantly lower than registered by the Fitbit activity tracker.

CONCLUSIONS

Physical activity tracking and self-monitoring can help to improve patients with prediabetes weight control and prevent obesity. This is the part of the pilot study, but the results are promising, and the research with large sample size, control group, and healthy subjects should be taken.
Smart Attendance Marking System Using Bluetooth Low Energy and Facial Recognition Technology
Authors: Narayanan Dr. V. Anantha
Published: February 2022

Abstract: The process of taking attendance manually can be troublesome and time consuming. However taking attendance is mandatory in most of the educational institutions in India. The usual process of taking attendance involves the faculty manually calling out the names of the students in an order and marking his/her presence in a sheet of paper. The existing method of marking attendance is slow and students may fool the faculties in marking proxies if the classroom strength is large enough. There are various ways to automate the attendance marking process using technologies like biometric sensors , RFID cards , facial recognition , BLE beacon cards etc. This paper focuses on implementing a BLE beacon based attendance marking system with facial recognition technology for authentication. It uses BLE beacon cards communicate with android application to enable marking attendance. The app uses facial recognition technology to authenticate every user before marking attendance. This makes the process of marking attendance faster and is proxy safe. Index Terms: Bluetooth low energy, BLE peripheral, android, automated attendance management, facial recognition authentication, BLE encryption.
Assessment of Heavy Metals in Fruits and Vegetables Collected from Bareilly Local Market, Uttar Pradesh State, India
Authors: Sharma Deepali , Bisla Gita
Published: February 2022

Abstract: Heavy metals are among the contaminating agents of our food supply, and the main source of metals or the media through which living beings get exposed to various toxic metals is food and water. The concentration of heavy metals in plants is essential for good health and growth of human and animals but should be within permissible limits. Various natural and anthropogenic factors are responsible for excess metal concentration in crops. Dietary heavy metals such as cadmium, lead, arsenic, mercury can be harmful to biota as their excessive accumulation in human body can lead to systematic health problems. Fruits and vegetables are main component in diet after cereals. Hence the present study aimed to determine Aluminium (Al), Arsenic (As), Cadmium (Cd), Lead (Pb) and Mercury (Hg) content in mostly consumed vegetables (onion, potato, taro root, spinach, taro root leaves, beans, jackfruit and pumpkin) and fruits (blackberry, mango and pears) during summers in Bareilly City, Uttar Pradesh. These food samples were collected from local vendors and shops from four different market sites of the city. The samples were analysed using atomic absorption spectrophotometer and the obtained results were compared with safe limits set by different national and international agencies. Based on the data we conclude that concentrations (mg/kg dry weight) of As, Pb and Hg for all samples and Al and Cd for most of the food stuffs were found exceeding the allowable limits causing potential health risk to consumers of present study area. Elevated levels of these metals in food stuffs might be due to various factors such as usage of industrial and disposal waste water for irrigation, municipal and urban runoff, fertilizers, pesticides, that contaminates the soil and hence crops absorb those metals. Some cultivation areas get exposed to atmospheric pollution found near highways, in form of metal containing aerosols. Other factors can be exposure to pollution during transportation and marketing. The prolonged consumption of unsafe concentration of metals is an alarming public health concerns, considering that metals can accumulate in organism and show negative effects by causing various disruptions of numerous biochemical processes and therefore leading to acute and chronic health outcomes. Such foodstuffs should be avoided in the diet and a regular monitoring is required to avoid the health risk among humans.
