The perception of using social media – a comparison of entrepreneurs implementing CSR in managerial practice and other entrepreneurs in selected V4 countries
Authors: Metzker Zdenko , Belas Jaroslav , Amoah John
Published: July 2021

The article aims to identify the perception of issues related to the use of social media in the business environment of small and medium-sized enterprises in the Czech Republic, Hungary, and Poland. The authors chose the concept of comparing entrepreneurs who implement corporate social responsibility with other interviewed entrepreneurs. An interesting comparison was made from the collected data. The article is based on a questionnaire survey of 1217 respondents. The study was conducted from September 2019 to January 2020. The chi-quadrat test and z-score were used to evaluate statistical hypotheses. The results showed that Czech entrepreneurs implementing corporate social responsibility have more negative answers than the surveyed entrepreneurs in other countries. Thus, less than 28% of Czech corporate social responsibility entrepreneurs agree that social media helps increase corporate growth, while in Poland – up to 49%. As many as 53% of corporate social responsibility entrepreneurs in Hungary and Poland agreed that social media could respond more flexibly to market developments. Czech entrepreneurs were lagging behind 35% of them. The results showed no statistically significant differences in all research questions regarding entrepreneurs without the implemented CSR concept. The article results suggested that Czech CSR entrepreneurs did not see the potential benefits of social media use. Although the study focuses only on 3 central European countries, the results are not generalizable. However, they are useful for those who promote positive impacts on companies through the social networks and organizations that promote corporate social responsibility. One of the tools for transparent communication with customers/suppliers could be by communication via social media. The study's findings could further help other entrepreneurs consider the benefits of social media in doing socially responsible business.

Published: July 2021

We present an otherwise healthy, fully immunized 12-year-old girl who was transferred intubated and ventilated to our Paediatric Intensive Care Unit with fever, cough, and acute respiratory failure. The epidemiologic history was positive for COVID-19, and, furthermore, she tested PCR positive resulting from a nasopharyngeal swab. CT of the thorax revealed bilateral consolidation with the tree-in-bud signs. Her condition required artificial ventilation support for 13 days. Remdesivir, pronation, high dose Ascorbic acid with Thiamine, and combined antimicrobial therapy were successfully used. Our patient made a full clinical recovery. The case demonstrates that even though critical course of COVID-19 infection in children is scarce, it might occur. We hereby would like to share our experience with the medical community.
Local detailed balance
Authors: Maes Christian
Published: July 2021

We review the physical meaning and mathematical implementation of the condition of local detailed balance for a class of nonequilibrium mesoscopic processes. A central concept is that of fluctuating entropy flux for which the steady average gives the mean entropy production rate. We repeat how local detailed balance is essentially equivalent to the widely discussed fluctuation relations for that entropy flux and hence is at most ``only half of the story.''

Published: July 2021

The role of a leader is fundamental to increase organizational culture and facilitate employee engagement. However, organizations are not providing clear guidance on how to do it. This study aims to determine the relationship between leadership styles and employee engagement as well as to understand whether there is a correlation between an engaged employee and extra effort. The study uses a Multi-Leadership Questionnaire (MLQ-5x Rater Form) to measure employee perception of the leader styles and Utrecht Work Engagement Scale (UWES-17) to determine employee engagement. The scope of the study is limited to a sample of 167 employees from 7 different multinational companies and 31 different nationalities.Results show that all the transformational behaviors and, concretely the idealized behavior, are significantly positively related to work engagement in multinational environments. Results also reveal a strong correlation between employee engagement and extra effort. The study concludes that leaders or managers should use transformational behaviors if they want to increase engagement and extra effort with their teams. They should increase transformational behaviors like being transparent, consistent, and having a strong sense of purpose to catalyze a collective engagement. These results expand previous studies of transformational leadership and work engagement in multinational environments.

Published: July 2021

The Costa Azul wastewater treatment plant is situated in Carlos Paz city (Córdoba, Argentina). The treated water is discharged to the San Roque reservoir, which is the source of water for the city of Córdoba and surrounding towns. Consequently, it is of great importance to evaluate the potential impact on the water quality reservoir for the preservation of public health. Currently, the WWTP lacks an accurate flow monitoring system at the last treatment: disinfection. This problem led to the development of a methodology in which experimental in-situ work and computational fluid dynamics (CFD) were applied, in a combined way, to calibrate the flow measurement system. First, large-scale particle image velocimetry (LS-PIV) was applied. The results made it possible to obtain characteristic parameters of the average flow: cross-sectional velocity profiles, recirculation and flow stagnation zones, flow discharge and characteristic parameters of the contact chamber. Second, numerical models, based on the Reynolds-average Navier–Stokes equations with the k–ε turbulent closure model were used. Based on the simulation results, it was possible to calibrate the discharge equation for a rectangular weir, and elaborate recommendations to improve the discharge measurement system and hydraulics in the area of the contact chamber curves.

Authors: Ruan Jun , He Gang
Published: July 2021

The study of water resource security is a basic scientific issue that must be faced in the construction of the ecological environment. To examine the status of regional water resources security in the Huaihe Eco-economic Belt, this study builds a comprehensive evaluation index system based on the ‘Driving-Pressure-State-Impact-Response’ (DPSIR) framework, combines the entropy weight method and Lotka–Volterra symbiosis model to calculate the water resources security status from 2010 to 2018. Then the fixed effects regression model is used to analyze the factors affecting the water resources system. The results show that: (1) The status of water resources security in the Huaihe Eco-economic belt decreased from 2011 to 2017 and, thereby transitioned from a safe to a dangerous state. The coordination index of the economic system and water resource system was only −0.17 in 2017, and the partial development model benefited the economy but damaged the water resources. (2) The security status of 25 prefecture-level cities improved significantly, and the number of cities with status of alert or above increased from 11 to 15. However, there are apparent differences among the regions. The status has shifted to ‘north and south being better than east and west’. The water resources security status of Jining, Linyi, and Lu'an have improved, whereas Yancheng, Taizhou, Pingdingshan, and other cities showed rather poor development during 2017. (3) The correlation coefficient of the economic system was −0.154 and hindered the development of the water resources system. The correlation coefficients of the added value of the tertiary industry and the expenditure on energy conservation and environmental protection was 0.699 and 0.180 respectively and played a positive role in promoting the water resources system. It is necessary to optimize and adjust the industrial structure and protect the environment.
EXPERIMENTAL STUDY OF THE TRANSFER OF MICROPARTICLES IN A THIN LIQUID LAYER UNDER THE INFLUENCE OF A TEMPERATURE GRADIENT
Authors: AL-MUZAIQER Mohammed Ali Yahya Ali , FLYAGIN Victor M. , Obaid Obaid Gardoon Luqman , IVANOVA Natalya A.
Published: July 2021

This article studies the main regularities of polyethylene microparticles transfer process in a layer of volatile and non-volatile fluid by thermocapillary currents under local heating and cooling. The authors show the possibility of creating circular and ring-shaped patterns by inducing positive and negative radial-directional temperature gradients.
A methodology and computer program have been developed to quantify the transfer process, consisting in measuring the area of the particle pattern (assembly) formed during heating and the area freed from the particles (cleaning area) during cooling on a sequence of video recording frames obtained with an optical microscope. This technique is based on comparing the intensity of image pixels with respect to a threshold value and counting the total area of pixels occupied or not occupied by particles.
The influence of such experiment parameters as the volume of the carrier fluid (layer thickness), at a constant number of particles, fluid evaporation and the ratio of particle and fluid densities on the size of the resulting pattern and the time of reaching the steady state has been established. The results show that the area of the final pattern during local heating and the clearing area, during local cooling, tends to decrease with increasing layer thickness, while the time of reaching the steady state does not depend on the layer thickness, but depends on the properties of the liquid and the ratio of particle and liquid densities.
METHOD FOR STUDYING THE INFLUENCE OF THERMAL INERTIA ON THE ROOM TEMPERATURE
Authors: ROMAZANOV Artur R. , ZAKHAROVA Irina G.
Published: July 2021

The efficiency of using thermal energy that is received from the central heating system to supply a building (a complex of interconnected rooms) is determined by the completeness of information available on the factors that affect the thermal regime. This article presents an approach that allows evaluating the significance for thermal management of such complex parameters as thermal inertia of a room and features of its use. The proposed methodology is based on the analysis of the dynamics of temperature changes in rooms, considering the standard characteristics that determine heat exchange, meteorological conditions, and the presence of people. The degree of the thermal inertia influence on a room is determined on the lag time, which is the time interval between a significant change in weather conditions or the supply of thermal energy and a change in the air temperature in the room. The initial data included the values of the temperature of the air and heating elements, that were obtained from the sensors located in a university building. The observation was conducted between 1 March and 19 April 2020 (measurement frequency — 10 minutes). The collected data consist of measurements gathered during room usage in different modes. Additionally, the presence of periods of complete shutdown of the heating system also affected the respective data. The module of the intelligent monitoring system for the thermal regime of the building was developed to perform data analysis. The module was implemented as a pipeline that sequentially performs the following operations: filtering and cleaning data; aggregation for specified periods; determination of the delay time. The results of the data analysis show the possibility of selecting groups of rooms that react to significant changes in external conditions and heating mode with a remarkable lag time. This confirms the importance of considering the thermal inertia for efficient heating control (intermittent operation). The results allow concluding that it is possible to build a classification model based on the thermal inertia parameter. These models will help in determining the most significant factors affecting the thermal regime of the room. In its turn, it allows producing recommendations for making decisions on heat supply management.

Published: July 2021

This article presents the results of a numerical simulation and an experimental study of the electrical circuit of a hardware spiking perceptron based on a memristor-diode crossbar. That has required developing and manufacturing a measuring bench, the electrical circuit of which consists of a hardware perceptron circuit and an input peripheral electrical circuit to implement the activation functions of the neurons and ensure the operation of the memory matrix in a spiking mode. The authors have performed a study of the operation of the hardware spiking neural network with memristor synapses in the form of a memory matrix in the mode of a single-layer perceptron synapses. The perceptron can be considered as the first layer of a biomorphic neural network that performs primary processing of incoming information in a biomorphic neuroprocessor. The obtained experimental and simulation learning curves show the expected increase in the proportion of correct classifications with an increase in the number of training epochs. The authors demonstrate generating a new association during retraining caused by the presence of new input information. Comparison of the results of modeling and an experiment on training a small neural network with a small crossbar will allow creating adequate models of hardware neural networks with a large memristor-diode crossbar. The arrival of new unknown information at the input of the hardware spiking neural network can be related with the generation of new associations in the biomorphic neuroprocessor. With further improvement of the neural network, this information will be comprehended and, therefore, will allow the transition from weak to strong artificial intelligence.

Authors: GILMANOV Alexander Ya. , FEDOROV Konstantin M. , SHEVELEV Alexander P.
Published: July 2021

This article analyzes the temperature distribution in a producer well at the primary stage of the steam-assisted gravity drainage process. The increase in share of hard-to-recover reserves requires using steam-assisted gravity drainage (SAGD). Its successful application, in turn, depends on warming up the inter-well zone, which demands steam circulation in both wells at the primary stage of the process. The duration of this stage affects the transition to oil production and the profitability of the process, which emphasizes the importance of analyzing thermal fields at this stage to assess its duration. The existing research does not allow estimating the temperature in the producer, using the correct formulation of the problem. This paper presents the temperature distribution in a producer for SAGD for classical and chess well patterns for the first time. The aim of the work is to choose a development system for the minimum duration of primary stage of SAGD. For this purpose, the fundamental solution of the non-stationary heat equation for a continuous stationary point source in an unbounded medium is used. The estimation of temperature, at which oil becomes mobile, allows determining the primary stage duration. The authors compare the classical and chess well patterns. In addition, they have obtained the temperature distribution in producer. The results show that classical well pattern provides faster heating of inter-well zone. It is determined that the closest injection well has the greatest influence on the temperature in the producing well.
Mechanistic Aspects of Medicinal Plants and Secondary Metabolites against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)
Authors: Malekmohammad Khojasteh , Rafieian-Kopaei Mahmoud
Published: July 2021

Background and Objective:

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), a
highly pathogenic virus, is responsible for a respiratory disease termed coronavirus disease 2019 (COVID-19).
SARS-CoV-2 genome encodes various structural and non-structural proteins, which are necessary for viral entry
and replication. Among these proteins, papain-like protease (PLpro), 3C-like protease (3CLpro), RNAdependent
RNA polymerase (RdRp), helicase, serine protease, and spike protein are potential targets of herbal
remedies and phytocompounds for inhibition of viral infection and replication. There is, at present, no confirmed
cure for the COVID-19. Various plants and their components have been introduced against SARS-CoV-2.
A number of review articles have also been published on them. This article is focused on the mechanistic aspects
of these plants and their derivatives on SARS-CoV-2.

Methods:

The material in this review article was prepared from significant scientific databases, including Web
of Science, PubMed, Science Direct, Scopus and Google Scholar.

Results:

Different medicinal plants and their phytocompounds interact with important structural and nonstructural
of SARS-CoV-2 proteins. Natural compounds form strong bonds with the active site of SARS-CoV-2
protease and make large conformational changes. These phytochemicals are potential inhibitors of structural
and non-structural SARS-CoV-2 proteins such as Spike protein, PLpro, and 3CLpro. Some important anti-
SARS-CoV-2 actions of medicinal plants and their metabolites are: inhibition of the virus replication or entry,
blocking the angiotensin-converting enzyme 2 (ACE-2) receptor and “Transmembrane protease, serine 2
(TMPRSS2), regulation of inflammatory mediators, inhibition of endothelial activation, toll-like receptors
(TLRs) and activation of the nuclear factor erythroid-derived 2-related factor 2 (Nrf2). Some of these important
natural immune boosters that are helpful for the prevention and cure of various symptoms related to COVID-19
include Allium sativum, Nigella sativa, Glycyrrhiza glabra Zingiber officinalis, Ocimum sanctum, Withania
somnifera, Tinospora cordifolia, and Scutellaria baicalensis. Also, Kaempferol, Quercetin, Baicalin, Scutellarin,
Glycyrrhizin, Curcumin, Apigenin, Ursolic acid, and Chloroquine are the best candidates for treating the
symptoms associated with SARS-CoV-2 infection.

Conclusion:

Medicinal plants and/or their bioactive compounds with inhibitory effects against SARS-CoV-2 support
the human immune system and help in fighting against COVID-19 and rejuvenating the immune system.
Recombinant Active Peptides and their Therapeutic Functions

Published: July 2021

Recombinant active peptides are utilized as diagnostic and biotherapeutics in various maladies and as bacterial growth inhibitors in the food industry. This consequently stimulated the need for recombinant peptides' production, which resulted in about 19 approved biotech peptides of 1-100 amino acids commercially available. While most peptides have been produced by chemical synthesis, the production of lengthy and complicated peptides comprising natural amino acids has been problematic with low quantity. Recombinant peptide production has become very vital, cost-effective, simple, environmentally friendly with satisfactory yields. Several reviews have focused on discussing expression systems, advantages, disadvantages, and alternatives strategies. Additionally, the information on the antimicrobial activities and other functions of multiple recombinant peptides is challenging to access and is scattered in literature apart from the food and drug administration (FDA) approved ones. From the reports that come to our knowledge, there is no existing review that offers substantial information on recombinant active peptides developed by researchers and their functions. This review provides an overview of some successfully produced recombinant active peptides of ≤100 amino acids by focusing on their antibacterial, antifungal, antiviral, anticancer, antioxidant, antimalarial, and immune-modulatory functions. It also elucidates their modes of expression that could be adopted and applied in future investigations. We expect that the knowledge available in this review would help researchers involved in recombinant active peptide development for therapeutic uses and other applications.

Authors: Koush Wafaa A. , Labena Ahmed , Elsawy Hany , Farahat Laila A. , Mohamed Tarek M. , Salem Maha M.
Published: July 2021

Background and Aim:

This study aims to alleviate the microbiologically affected corrosion
that occurred by sulfate-reducing bacteria (SRB) through synthesizing a bio-based polyurethane
polymer and its nanocomposite coating, silver nanoparticles (PU-Ag). Moreover, it will also
evaluate the effect of PU alone and PU-Ag as inhibitors for adenylyl sulfate reductase (APS), the
main enzyme for sulfate reduction.

Methods:

In this study, the PU was prepared from vegetable soybean oil, and the silver nanoparticles
(Ag-NPs) with a concentration of 1% were coated to the PU forming a nanocomposite. The
PU and the PU-Ag were characterized and evaluated as inhibitors of the APS reductase enzyme.

Results:

The results obtained from FTIR, UV, DLS, TEM, and XRD confirmed the preparation
structure of the PU and PU-Ag. Furthermore, the PU/PU-Ag competitively inhibited the APS reductase
with an inhibition constant equal to 35.7 and 11 mg, respectively. These indicated the exerted
inhibitory effect of PU/PU-Ag upon the activity of the APS reductase enzyme.

Conclusion:

The APS reductase enzyme produced by SRB, which is recorded as a big problem in
the oil and gas industry such as pitting corrosion of tanks and pipelines, could be inhibited by PU
and PU-Ag.

VARIETY OF DIAGNOSED MICROORGANISMS IN PATIENTS WITH ERYSIPELAS
Authors: Vasilevskaya L. A. , Shapoval S. D.
Published: July 2021

Purpose. The purpose is to find out the frequency of surgical forms of erysipelas among the general population of the disease.
Materials and methods. Traditionally, there is a widespread point of view about streptococcal etiology of erysipelas. However, recently, staphylococcus or microbial associations are increasingly sown from the focus of inflammation in patients.
The relevance of studying the course of erysipelas is determined by the tendency to relapse, a significant increase in complications of the disease in recent years and the final phenomena.
The existing clinical situation is largely explained by changes in the spectrum of pathogens of purulent surgical infection of soft tissues. Its leading pathogens are mainly staphylococci and streptococci, as well as gram - negative aerobic bacteria.
The nature of the clinical course of the disease, including the nature of the local inflammatory focus, depends on the totality of the pathogenic properties of microbes that form the microbial landscape.
It was found that most often the local focus was localized on the lower extremities.
114 case histories of patients who were hospitalized in the center of purulent-septic surgery in the Non-profit municipal enterprise “City Hospital № 3” in Zaporizhzhia for the period 2019-2020 were analyzed retrospectively and prospectively. All patients were diagnosed with erysipelas on admission, according to the forms: erythematous - 24 (21.0%), bullous - 28 (24.6%), phlegmonous form - 48 (42.1%), necrotic - 14 (12.3%). %). Disease relapses were noted in 21 patients. In terms of gender: men - 47 (41.2%), women - 67 (58.8%). The patients' age was 62.1 ± 2.6 years. Automated devices "Vitek-2" or "BaCT ALERT" (France) were used to determine the sensitivity of microorganisms in a purulent focus to antibacterial drugs. Statistical analysis was performed using the “Statgraphics Plus for Windows 7.0” software package.
Research results and their analysis. It was found that most often the local focus was localized on the lower extremities. A total of 26 types of bacteria were identified from the wound contents of patients with destructive forms of erysipelas. No bacterial growth was found in 3 (4.8%) patients, and mixed flora was isolated in 27 (45.8%) patients. Gram-positive flora accounted for 61.0%, gram-negative flora - 35.6%, anaerobes - were not found, fungi - 3.4%.
Conclusions. The number of destructive forms of erysipelas among the general population of the disease is more than 50%. The study of purulent-necrotic foci in patients with destructive forms of erysipelas makes it possible to determine the qualitative and quantitative composition of microflora, sensitivity to antibiotics, and make adjustments to the conduction of antibiotic therapy.

A nemzetközi szakirodalomban a térdsérülések, keresztszalag szakadások sokszor visszavezethetők az alsó végtag izomzatának nem kielégítő működésére, illetve izomgyengeségére. A statikusan, illetve dinamikusan mért megnövekedett értéket mutató Q (quadriceps) szög – az eddigi vizsgálatok alapján – erősen korrelál a térdfájdalommal, illetve a térdsérülések kialakulásának kockázatával. A Q szög a combfeszítő izom (m.quadriceps femoris), azon belül is az egyenes combizom (rectus femoris) eredési pontjától, vagyis az elülső alsó csípőtövistől kiinduló, és a térdkalács középpontján átmenő egyenes, valamint a sípcsonti érdesség és a térdkalács középpontján átfutó egyenes által bezárt szög. A funkcionális tesztek – pl. egylábas guggolás, lépcsőn járás, lépcsőről lelépés – során tapasztalt, medial irányba befelé billenő térd, azaz a dinamikus valgus helyzetbe forduló térd, izomgyengeségre enged következtetni, mely a sérülés kialakulása szempontjából rizikófaktornak tekinthető. A prevenció manapság a statikusan mért Q szög helyett inkább a dinamikus helyzetben realizálható Q értéket veszi figyelembe. A megnövekedett Q érték szerepet játszik az oszteoartritisz, keresztszalag sérülés, patellofemoralis fájdalom és egyéb térdproblémák kialakulásában is. A dinamikus Q szög értéke a nemzetközi kutatások alapján rendszeres fizikai aktivitással, illetve alsó végtagra kiterjedő mozgásprogrammal sikeresen és eredményesen csökkenthető. A mozgásterápiának igen jelentős szerepe jut mind a népesség átlag egészségi állapotának a fejlesztésében, mind pedig a sportolók és versenyzők sérülés megelőzésében. Az erőfejlesztő edzések technika javító edzésekkel együtt még inkább hatásosnak bizonyultak.

Background

Diagnostics in many low- and middle-income countries are conducted through centralized laboratory networks. Samples are collected from patients at remote point-of-care health facilities, and diagnostic tests are performed at centralized laboratories. Sample transportation systems that deliver diagnostic samples and test results are crucial for timely diagnosis and treatment in such diagnostic networks. However, they often lack the timely and accurate data (eg, the quantity and location of samples prepared for collection) required for efficient operation.

Objective

This study aims to demonstrate the feasibility, adoption, and accuracy of a distributed data collection system that leverages basic mobile phone technology to gather reports on the quantity and location of patient samples and test results prepared for delivery in the diagnostic network of Malawi.

Methods

We designed a system that leverages unstructured supplementary service data (USSD) technology to enable health workers to submit daily reports describing the quantity of transportation-ready diagnostic samples and test results at specific health care facilities, free of charge with any mobile phone, and aggregate these data for sample transportation administrators. We then conducted a year-long field trial of this system in 51 health facilities serving 3 districts in Malawi. Between July 2019 and July 2020, the participants submitted daily reports containing the number of patient samples or test results designated for viral load, early infant diagnosis, and tuberculosis testing at each facility. We monitored daily participation and compared the submitted USSD reports with program data to assess system feasibility, adoption, and accuracy.

Results

The participating facilities submitted 37,771 reports over the duration of the field trial. Daily facility participation increased from an average of 50% (26/51) in the first 2 weeks of the trial to approximately 80% (41/51) by the midpoint of the trial and remained at or above 80% (41/51) until the conclusion of the trial. On average, more than 80% of the reports submitted by a facility for a specific type of sample matched the actual number of patient samples collected from that facility by a courier.

Conclusions

Our findings suggest that a USSD-based system is a feasible, adoptable, and accurate solution to the challenges of untimely, inaccurate, or incomplete data in diagnostic networks. Certain design characteristics of our system, such as the use of USSD, and implementation characteristics, such as the supportive role of the field team, were necessary to ensure high participation and accuracy rates without any explicit financial incentives.
Efficacy of a Just-in-Time Adaptive Intervention to Promote HIV Risk Reduction Behaviors Among Young Adults Experiencing Homelessness: Pilot Randomized Controlled Trial

Published: July 2021

Background

People experiencing homelessness have higher rates of HIV than those who are stably housed. Mental health needs, substance use problems, and issues unique to homelessness such as lack of shelter and transiency need to be considered with regard to HIV prevention. To date, HIV prevention interventions for young adults experiencing homelessness have not specifically addressed modifiable real-time factors such as stress, sexual or drug use urge, or substance use, or been delivered at the time of heightened risk. Real-time, personalized HIV prevention messages may reduce HIV risk behaviors.

Objective

This pilot study tested the initial efficacy of an innovative, smartphone-based, just-in-time adaptive intervention that assessed predictors of HIV risk behaviors in real time and automatically provided behavioral feedback and goal attainment information.

Methods

A randomized attention control design was used among young adults experiencing homelessness, aged 18-25 years, recruited from shelters and drop-in centers in May 2019. Participants were randomized to either a control or an intervention group. The intervention (called MY-RID [Motivating Youth to Reduce Infection and Disconnection]) consisted of brief messages delivered via smartphone over 6 weeks in response to preidentified predictors that were assessed using ecological momentary assessments. Bayesian hierarchical regression models were used to assess intervention effects on sexual activity, drug use, alcohol use, and their corresponding urges.

Results

Participants (N=97) were predominantly youth (mean age 21.2, SD 2.1 years) who identified as heterosexual (n=51, 52%), male (n=56, 57%), and African American (n=56, 57%). Reports of sexual activity, drug use, alcohol use, stress, and all urges (ie, sexual, drug, alcohol) reduced over time in both groups. Daily drug use reduced by a factor of 13.8 times over 6 weeks in the intervention group relative to the control group (Multimedia Appendix 4). Lower urges for sex were found in the intervention group relative to the control group over the duration of the study. Finally, there was a statistically significant reduction in reports of feeling stressed the day before between the intervention and control conditions (P=.03).

Conclusions

Findings indicate promising intervention effects on drug use, stress, and urges for sex in a hard-to-reach, high-risk population. The MY-RID intervention should be further tested in a larger randomized controlled trial to further investigate its efficacy and impact on sexual risk behaviors.

Background

Digital health interventions (DHIs) can alleviate several barriers to achieving better maternal and child health. The World Health Organization’s guideline recommendations for DHIs emphasize the need to integrate multiple DHIs for maximizing impact. The complex health system of Bangladesh provides a unique setting for evaluating and understanding the role of an electronic registry (eRegistry) for antenatal care, with multiple integrated DHIs for strengthening the health system as well as improving the quality and utilization of the public health care system.

Objective

The aim of this study is to assess the effect of an eRegistry with DHIs compared with a simple digital data entry tool without DHIs in the community and frontline health facilities.

Methods

The eRegMat is a cluster-randomized controlled trial conducted in the Matlab North and Matlab South subdistricts in the Chandpur district, Bangladesh, where health facilities are currently using the eRegistry for digital tracking of the health status of pregnant women longitudinally. The intervention arm received 3 superimposed data-driven DHIs: health worker clinical decision support, health worker feedback dashboards with action items, and targeted client communication to pregnant women. The primary outcomes are appropriate screening as well as management of hypertension during pregnancy and timely antenatal care attendance. The secondary outcomes include morbidity and mortality in the perinatal period as well as timely first antenatal care visit; successful referrals for anemia, diabetes, or hypertension during pregnancy; and facility delivery.

Results

The eRegistry and DHIs were co-designed with end users between 2016 and 2018. The eRegistry was implemented in the study area in July 2018. Recruitment for the trial started in October 2018 and ended in June 2020, followed by an 8-month follow-up period to capture outcome data until February 2021. Trial results will be available for publication in June 2021.

Conclusions

This trial allows the simultaneous assessment of multiple integrated DHIs for strengthening the health system and aims to provide evidence for its implementation. The study design and outcomes are geared toward informing the living review process of the guidelines for implementing DHIs.
