A Novel Framework of an IOT-Blockchain-Based Intelligent System

With the growing need of technology into varied fields, dependency is getting directly proportional to ease of user-friendly smart systems. The advent of artificial intelligence in these smart systems has made our lives easier. Several Internet of Things- (IoT-) based smart refrigerator systems are emerging which support self-monitoring of contents, but the systems lack to achieve the optimized run time and data security. Therefore, in this research, a novel design is implemented with the hardware level of integration of equipment with a more sophisticated software design. It was attempted to design a new smart refrigerator system, which has the capability of automatic self-checking and self-purchasing, by integrating smart mobile device applications and IoT technology with minimal human intervention carried through Blynk application on a mobile phone. The proposed system automatically makes periodic checks and then waits for the owner’s decision to either allow the system to repurchase these products via Ethernet or reject the purchase option. The paper also discussed the machine level integration with artificial intelligence by considering several features and implemented state-of-the-art machine learning classifiers to give automatic decisions. The blockchain technology is cohesively combined to store and propagate data for the sake of data security and privacy concerns. In combination with IoT devices, machine learning, and blockchain technology, the proposed model of the paper can provide a more comprehensive and valuable feedback-driven system. The experiments have been performed and evaluated using several information retrieval metrics using visualization tools. Therefore, our proposed intelligent system will save effort, time, and money which helps us to have an easier, faster, and healthier lifestyle.

Drug-Induced Atrial Fibrillation / Atrial Flutter

Drug-induced atrial fibrillation / flutter (DIAF) is a serious and potentially life-threatening complication of pharmacotherapy. Purpose of the work: systematization and analysis of scientific literature data on drugs, the use of which can cause the development of DIAF, as well as on epidemiology, pathophysiological mechanisms, risk factors, clinical picture, diagnosis and differential diagnosis, treatment and prevention of DIAF. Analysis of the literature has shown that many groups of drugs can cause the development of DIAF, with a greater frequency while taking anticancer drugs, drugs for the treatment of the cardiovascular, bronchopulmonary and central nervous systems. The mechanisms and main risk factors for the development of DIAF have not been finally established and are known only for certain drugs, therefore, this section requires further study. The main symptoms of DIAF are due to the severity of tachycardia and their influence on the parameters of central hemodynamics. For diagnosis, it is necessary to conduct an electrocardiogram (ECG) and Holter monitoring of an ECG and echocardiography. Differential diagnosis should be made with AF, which may be caused by other causes, as well as other rhythm and conduction disturbances. Successful treatment of DIAF is based on the principle of rapid recognition and immediate discontinuation of drugs (if possible), the use of which potentially caused the development of adverse drug reactions (ADR). The choice of management strategy: heart rate control or rhythm control, as well as the method of achievement (medication or non-medication), depends on the specific clinical situation. For the prevention of DIAF, it is necessary to instruct patients about possible symptoms and recommend self-monitoring of the pulse. It is important for practitioners to be wary of the risk of DIAF due to the variety of drugs that can potentially cause this ADR.

Revisiting Extraversion and Leadership Emergence: A Social Network Churn Perspective

One of the classic relationships in personality psychology is that extraversion is associated with emerging as an informal leader. However, recent findings raise questions about the longevity of extraverted individuals as emergent leaders. Here, we adopt a social network churn perspective to study the number of people entering, remaining in, and leaving the leadership networks of individuals over time. We propose that extraverted individuals endure as emergent leaders in networks over time, but experience significant changes in the people being led, including the loss of people who once considered them a leader but now no longer do. In Study 1 (N = 545), extraverted individuals had a larger number of new and remaining people in their leadership networks, but also lost more people, above and beyond differences in initial leadership network size. In Study 2 (N = 764), we replicated and extended these results in an organizational sample while controlling for alternative explanations such as formal rank, network size, self-monitoring, and narcissism. Extraversion predicted the number of people entering, remaining in, and leaving leadership networks over time. Our findings suggest that while extraverted individuals tend to emerge as leaders, they are also more likely to experience greater network churn—they tend to lead different people over time and leave people in their wake who once perceived them a leader but now no longer do. We discuss the challenges posed by this network churn perspective for extraverted emergent leaders and highlight its importance for our understanding of extraversion and emergent leadership.

The role of non-drug methods of increasing adherence to the treatment of patients with arterial hypertension in a polyclinic

Introduction. Arterial hypertension (AH) is one of the important high-risk factors for the development of heart diseases, but its diagnosis and treatment does not require high technologies and substantial costs. However, the asymptomatic course of AH combined with a low level of medical literacy contributes to low adherence to treatment.Aim. To study the indirect impact of remote blood pressure monitoring (RBPM), the introduction of educational materials (EMs) in comparison with self-monitoring of blood pressure (SMBP) on adherence of patients with AH to outpatient treatment.Materials and methods. 60 subjects with an established fact of partial or complete refusal to use antihypertensive therapy were enrolled in the study and randomized into four equal and comparable groups: 1 – SMBP, 2 – RBPM, 3 – SMBP + EMs, 4 – RBPM + EMs. The impact of using RBPM was assessed by comparing blood pressure values in groups 1 and 2; the impact of EM – by comparing the results of questionnaire surveys in groups 1 and 2 and groups 3 and 4.Results and discussion. Additional training of patients with AH contributed to a twofold increase in adherence in using SCAD and RBPM. The average systolic blood pressure in groups 1 and 2 was 134 mm Hg, in groups 3 and 4 – 129 mm Hg; diastolic blood pressure in groups 1 and 2 – 78.5 mm Hg, in groups 3 and 4 – 77.5 mm Hg.Conclusion. The maximum impact on adherence to AH treatment can be achieved with the introduction of a set of measures. However, the introduction of RBPM has a number of limitations associated with the additional economic burden and the lack of an approved methodology. However, the provision of treatment and prevention facilities with EMs does not require additional development of methodology and is significantly cheaper than the cost of modern blood pressure monitors.

The Effectiveness of Gallery Run Technique on Saudi EFL Upper-Intermediate Students’ Speaking Skill: Learners’ Attitudes in Focus

Gallery Run (GR) is a classroom-based dynamic learning technique that promotes higher-order thinking and co-operative learning. This research study examined the influence of GR strategy on Saudi upper-intermediate English as a foreign language(EFL) learners’ oral skills. First off, 62 upper-intermediate EFL learners from a language school in Riyadh were opted and randomly sectioned into an experimental group and a control group. Then, the participants in the two groups were given a speaking pretest. The experiment group applied the GR technique in their classroom, whereas the control group received no treatment and continued with an ordinary classroom program. After two-month classes, a speaking posttest was given to the two groups. To analyze the data collected, Independent and Paired Samples T-tests were conducted. The results showed that the experimental group excelled and outperformed the control group. The results also showed that 25.8% and 48.3% of the participants agreed and strongly agreed respectively that the GR technique enhanced their self-dependence. Furthermore, 45% of the participants reported that the ambiance was delightful, which conduced to the amelioration of their speaking competence. Another significant result was that 61.2% and 19.3% of the learners strongly agreed and agreed respectively that GR reduced the levels of loneliness and social anxiety. Furthermore, 58.1% strongly agreed that the GR technique did not put them under any kind of stress, nor did it encourage social loafing. A final finding reported by the 48.4 % of the learners was that GR reduced their alexithymia, social anxiety, and self-monitoring.

Problems of blood glucose self-monitoring in patients with diabetes mellitus

Glycemic self-monitoring is essential in the treatment of diabetes mellitus. Compliance with the recommendations for selfmonitoring of glycemia is an important condition for the prevention of diabetes complications. The article provides a review of the problems associated with blood glucose self-monitoring faced by diabetic patients and doctors. These include low frequency of blood glucose self-monitoring, technical errors in glucose measurements, errors in keeping a diary and errors in using measurement data to diabetes control. The blood glucose monitoring system, which includes the glucometer, test strips, application, сloud for data storage can be used for blood glucose self-monitoring in patients with diabetes mellitus. The article discusses the features and advantages of the blood glucose monitoring system. The advantages of the glucometer are the no сoding technology and the following options: аpplication of additional amount of blood to the test strip; adding meal marks, testing as the measurement results compare with targets and informing about it; storage a large number of measurement results. In addition to the standard blood glucose measurement, the glucose meter and the application offer many features to improve blood glucose self-monitoring that can help to improve diabetes management: automatic transferring measurement results to smartphone or tablet; saving notes in logbook; display of glucose trends and testing as they compare with targets; offering quick and valuable tips for critical high/low glucose values.

Supporting Self-Management and Quality of Life in Bipolar Disorder with the Beta PolarUs App: Protocol for a Mixed-Methods Study (Preprint)

BACKGROUND Quality of life (QoL) is increasingly recognised as a key outcome of self-management interventions for bipolar disorder (BD). Mobile phone applications (apps) can increase access to evidence-based self-management strategies and provide real-time support. However, while individuals with lived experience desire support with monitoring and improving broader health domains, existing BD apps largely target mood symptoms only. Further, evidence from the broader mHealth literature has shown that the desires and goals of end-users are not adequately taken into account during app development, and as a result engagement with mental health apps is suboptimal. To capitalise on the potential of apps to optimise wellness in BD, there is a need for interventions developed in consultation with real-world users that are designed to support QoL self-monitoring and self-management. Objective: This mixed methods pilot study is designed to evaluate the beta version of the newly developed PolarUs app, which aims to support QoL self-monitoring and self-management in people with BD. Developed using a community-based participatory research framework, the PolarUs app builds on the web-based adaptation of a BD-specific QoL self-assessment measure, and integrates material from a web-based portal providing information on evidence-informed self-management strategies in BD. OBJECTIVE The primary objectives of this project are to: (1) evaluate PolarUs app feasibility (via behavioral usage metrics); (2) evaluate PolarUs impact (via the Brief Quality of Life in Bipolar Disorders, QoL.BD scale, our primary outcomes measure); and (3) explore engagement with the PolarUs app (via both quantitative and qualitative methods). METHODS Study participants will be North American residents (N=150) aged 18-65 years with a DSM-5 diagnosis of BD-I, BD-II or BD not otherwise specified (NOS) as assessed by a structured diagnostic interview. An embedded mixed-methods research design will be adopted; qualitative interviews with a purposefully selected sub-sample (~n=30) of participants will be conducted to explore in more depth feasibility, impact and engagement with the PolarUs app over the 12-week study period. RESULTS At the time of publication of this protocol, the development of the beta version of the PolarUs app is complete. Participant enrollment is expected to begin in February 2022. Data collection is expected to be completed by December 2022. CONCLUSIONS Beyond contributing knowledge on the feasibility and impacts of a novel app to support QoL and self-management in BD, this study is also expected to provide new knowledge on engagement with mHealth apps. Furthermore, it is expected to function as a case study of successful co-design between individuals living with BD, clinicians who specialise in the treatment of BD, and BD researchers, providing a template for future use of community-based participatory research frameworks in mHealth intervention development. Results will be used to further refine the PolarUs app and inform the design of a larger clinical trial.
