Introduction:

ST-elevation myocardial infarction (STEMI) is known to be associated
with significant arrhythmia and consequent mortality. QT prolongation is a risk factor for arrhythmia
in STEMI patients who underwent primary percutaneous coronary intervention (PPCI). The aim
of this investigation was to evaluate the association of corrected QT interval (QTc), QT dispersion
(QTd), T-wave peak to end (TPE), and fragmented QRS with mortality in these patients.

Methods:

Eligible patients with the characteristic symptoms of STEMI who underwent PPCI were
included. QTc, QTd, TPE, and fragmented QRS were measured before and after the PPCI. These
predictors were compared between patients who died during hospitalization and discharged patients.

Results:

After coronary angiography, 10 patients (4%) died during the hospitalization after PPCI.
Comparing the non-survivers and discharged patients in terms of arrhythmia predictors showed that
the mean QT dispersion and TPE before intervention were significantly higher in the non-survivors.
Also, the number of patients who experienced fragmented QRS before and after the intervention
was significantly higher in the non-survivors.

Conclusion:

These data suggested that evaluating such arrhythmia predictors, especially before
PPCI, could be used as a predictor of mortality in STEMI patients who underwent PPCI.

Background:

Metal nanoparticles, such as silver nanoparticles obtained by “green” nanosynthesis, have been increasingly used in research and practice in recent years due to their high biocompatibility and low toxicity. It is important to understand how green nanoparticles have regulatory effects on all groups of living systems, including plants. One of the key questions is how silver nanoparticles obtained by green methods modify plant growth in various cultivation and biotechnological systems, such as in vitro culture.

Objective:

The aim of this study was to establish how in vitro culture of birch plants (Betula pendula Roth) reacts to different levels of silver nanoparticles synthesized by green methods (based on plant extracts) and chemical approaches.

Methods:

The paper examined the nodal segments of silver birch Betula pendula Roth grown on Woody Plant Medium (WPM) with the addition of silver nanoparticles (0.3-300 mg L-1). After 30 days of cultivation in an in vitro environment, the growth of shoots and roots was measured. Silver nanoparticles were synthesized using L-ascorbic acid (reducing agent) and polyvinylpyrrolidone (PVP; stabilizer), as well as with needle extract (as a reducing agent and stabilizer).

Results:

Chemical nanosynthesis based on PVP and L-ascorbate, as well as green nanosynthesis using extract of spruce needles made it possible to obtain spherical nanoparticles with similar physical parameters. Low levels of AgNPs (0.3-10 mg L-1) synthesized by chemical techniques (PVP and L-ascorbate) stimulated the growth of birch shoots. In this case, the maximum stimulating effect on shoot growth was found at 10 mg of L-1 AgNPs (250-300% stimulation compared to the control). Under higher levels of nanoparticles (30-300 mg L-1), the stimulating effect decreased. Concentrations over 300 mg of L-1 inhibited the growth of birch plants. Very similar effects were observed in roots.

In experiments with nanoparticles synthesized using spruce needle extract, it was shown that low concentrations of AgNPs (0.3 and 1 mg L-1) did not cause a significant change in the size of birch shoots and roots. At the same time, higher levels of silver nanoparticles (3-300 mg L-1) significantly stimulated growth.

Conclusion:

The present study demonstrates the production of stable silver nanoparticles based on PVP and L-ascorbic acid, as well as an extract of Betula pendula needles. The resulting nanoparticles have a uniform shape and distribution. The presence of AgNP (1-300 mg L-1) in the nutrient media has a stimulating effect on Betula pendula shoot and root growth.

Published: September 2022

This work concerns the use of different types of seeding agents and their effect on the isothermal crystallization of palm olein. In dry fractionation, palm olein usually shows slow crystallization, and seeding is a way to overcome this problematic. Starting with an olein iodine value ~ 57, experiments were conducted isothermally (15 °C and 17 °C) under shear, at lab-scale with a double-jacketed vessel. Different solutions were tested and compared: blending with palm oil, blending with palm stearin, addition of polyglycerol esters and addition of stearin micro-crystals. Crystallization kinetics were monitored by p-NMR during a full period of 6 hours; crystallization progress was assessed by optical microscopy (crystal morphology) and powder X-ray diffraction (polymorphism). The iodine values, the cloud points and the triglyceride compositions made it possible to characterize quality of the super olein obtained after vacuum filtration (iodine value ~ 60). All the tested conditions accelerated the crystallization kinetics. Blending with palm stearin was the most effective: in general, the obtained super olein had the highest iodine value, the lowest cloud point and the most depleted POP. Additional lab-scale crystallization experiments conducted in static conditions at 10°C tended to show the same trends; the best effect on crystal growth for the obtainment of super olein IV ~ 64 was also with palm stearin.

Justification: Biodegradable packaging films from biodiverse resources have gained popularity around the world in recent years due to environmental and sustainability concerns. A general challenge with biopolymer-based films is resistance against moisture and mechanical strength. We hypothesized that the functional properties of films from biopolymers can be improved by the presence of the sn-3 acetyl group of TAG, obtained from transgenic Camelina sativa. Objective:The aim of this study was to investigate the effect of acetyl-TAG as a plasticizer on the physiochemical properties of sorghum DDGS films.Methods:The acetyl-TAG with high oleic fatty acid composition (ca.70%) was extracted from transgenic camelina seeds using hexane. The composition of the purified oils was characterized by thin layer chromatography (TLC) and LC-MS. Sorghum DDGS were pretreated via wet (Colloid mill) and dry milling (Udy mill), and co-dissolved with gum plasticizers in a mixture of organic (i.e., ethanol, chloroform) and aqueous solvents. The acetyl-TAG was added to the mixture as a plasticizer (0, 0.1, 0.2% w/v). Films were characterized for their thermal properties (DSC), tensile strength, elongation (texture analyzer), thickness (micro caliper) and color (Hunter LAB colorimeter). ResultsAddition of acetyl-TAG significantly affected the mechanical properties of the films. Tensile strength significantly (p< 0.05) increased to 39.54 ± 0.04 MPa when acetyl-TAG (0.2% w/v) was added as compared to 20.77 ± 0.03 MPa of films without ace-TAG. The plasticizing resistance increased with the highest enthalpy of melting (2.51 J) for the films with 0.2% (w/v) ace-TAG. Physical properties, such as color, were significantly improved by addition of acetyl-TAG (i.e., the maximum lightness L* (66.7) obtained in with 0.2% ace-TAG).Significance:High oleic acetyl-TAG from engineered Camelina seeds can be used to improve the physicochemical properties of sorghum DDGS films as a novel and high-yield plasticizer.

Authors: Huang Heyin , Wang Yichen , Zhang Lanzhi , Zhang Qinxiu , Wu Xiaojuan , He Hengsheng
Published: September 2022

Background

The number of patients with allergic rhinitis (AR) has exceeded 500 million worldwide due to the unstable curative effect that can easily produce mental and psychological disorders. However, most of the relevant existing literature is one-on-one retrospective analyses or targeted meta-analyses of AR with psychological disorders like irritability, depression, and anxiety, while “multi-hospital + interdisciplinary” multiple regression analyses are scarce.

Objective

This study aims to precisely identify the psychological disorders of patients with AR who were diagnosed and treated in the five most renowned hospitals in Chengdu, China over the past 5 years using 10 classification methods so as to attract attention and care from otolaryngologists.

Methods

The Symptom Checklist 90 (SCL-90) was used to group and score the mental state of 827 strictly screened patients with AR according to 9 classification criteria. The scores were then compared within groups. Intergroup comparisons were made between the study group and the Chinese norm, and the positive factors for psychological disorders were extracted. Four symptoms in the study group, that is, nasal itching, sneezing, clear discharge, and nasal congestion, were scored on a visual analog scale. Partial correlation analysis was performed between the extracted positive factors for psychological disorders and the symptom scores by the multiple regression statistical method.

Results

Among 827 patients, 124 (15%) had no mental health impairments, 176 (21.3%) had mild impairments, 474 (57.3%) had mild to moderate impairments, 41 (5%) had moderate to severe impairments, and 12 (1.4%) had severe impairments. The average score of the SCL-90 for all 827 patients was 2.64 (SD 0.25), which corresponded to mild to moderate mental health impairments. The 827 patients scored significantly higher for the 4 positive factors: depression, anxiety, psychosis, and other (sleep, diet). Depression was positively correlated with sneezing and clear discharge, anxiety was positively correlated with nasal itching and congestion, psychosis was positively correlated with nasal itching and sneezing, and other (sleep, diet) was positively correlated with clear discharge and nasal congestion.

Conclusions

Patients with AR have mild to moderate mental health impairments, with women and those with abnormal BMI, aged ≥45 years, with a monthly salary <¥5110 (US $700), with a disease duration <13 years, residing in urban areas, with a high school or above education, or who are indoor laborers being at high risk and requiring more care, follow-up, and comprehensive therapy from otolaryngologists.
The Value of Electronic Health Records Since the Health Information Technology for Economic and Clinical Health Act: Systematic Review
Authors: Modi Shikha , Feldman Sue S
Published: September 2022

Background

Electronic health records (EHRs) are the electronic records of patient health information created during ≥1 encounter in any health care setting. The Health Information Technology Act of 2009 has been a major driver of the adoption and implementation of EHRs in the United States. Given that the adoption of EHRs is a complex and expensive investment, a return on this investment is expected.

Objective

This literature review aims to focus on how the value of EHRs as an intervention is defined in relation to the elaboration of value into 2 different value outcome categories, financial and clinical outcomes, and to understand how EHRs contribute to these 2 value outcome categories.

Methods

This literature review was conducted using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The initial search of key terms, EHRs, values, financial outcomes, and clinical outcomes in 3 different databases yielded 971 articles, of which, after removing 410 (42.2%) duplicates, 561 (57.8%) were incorporated in the title and abstract screening. During the title and abstract screening phase, articles were excluded from further review phases if they met any of the following criteria: not relevant to the outcomes of interest, not relevant to EHRs, nonempirical, and non–peer reviewed. After the application of the exclusion criteria, 80 studies remained for a full-text review. After evaluating the full text of the residual 80 studies, 26 (33%) studies were excluded as they did not address the impact of EHR adoption on the outcomes of interest. Furthermore, 4 additional studies were discovered through manual reference searches and were added to the total, resulting in 58 studies for analysis. A qualitative analysis tool, ATLAS.ti. (version 8.2), was used to categorize and code the final 58 studies.

Results

The findings from the literature review indicated a combination of positive and negative impacts of EHRs on financial and clinical outcomes. Of the 58 studies surveyed for this review of the literature, 5 (9%) reported on the intersection of financial and clinical outcomes. To investigate this intersection further, the category “Value–Intersection of Financial and Clinical Outcomes” was generated. Approximately 80% (4/5) of these studies specified a positive association between EHR adoption and financial and clinical outcomes.

Conclusions

This review of the literature reports on the individual and collective value of EHRs from a financial and clinical outcomes perspective. The collective perspective examined the intersection of financial and clinical outcomes, suggesting a reversal of the current understanding of how IT investments could generate improvements in productivity, and prompted a new question to be asked about whether an increase in productivity could potentially lead to more IT investments.

Authors: Savira Feby , Gupta Adyya , Gilbert Cecily , Huggins Catherine E , Browning Colette , Chapman Wendy , Haines Terry , Peeters Anna
Published: September 2022

Background

There has been a rapid shift toward the adoption of virtual health care services in Australia. It is unknown how widely virtual care has been implemented or evaluated for the care of older adults in Australia.

Objective

We aimed to review the literature evaluating virtual care initiatives for older adults across a wide range of health conditions and modalities and identify key challenges and opportunities for wider adoption at both patient and system levels in Australia.

Methods

A scoping review of the literature was conducted. We searched MEDLINE, Embase, PsycINFO, CINAHL, AgeLine, and gray literature (January 1, 2011, to March 8, 2021) to identify virtual care initiatives for older Australians (aged ≥65 years). The results were reported according to the World Health Organization’s digital health evaluation framework.

Results

Among the 6296 documents in the search results, we identified 94 that reported 80 unique virtual care initiatives. Most (69/80, 89%) were at the pilot stage and targeted community-dwelling older adults (64/79, 81%) with chronic diseases (52/80, 65%). The modes of delivery included videoconference, telephone, apps, device or monitoring systems, and web-based technologies. Most initiatives showed either similar or better health and behavioral outcomes compared with in-person care. The key barriers for wider adoption were physical, cognitive, or sensory impairment in older adults and staffing issues, legislative issues, and a lack of motivation among providers.

Conclusions

Virtual care is a viable model of care to address a wide range of health conditions among older adults in Australia. More embedded and integrative evaluations are needed to ensure that virtually enabled care can be used more widely by older Australians and health care providers.
Introducing a Framework for Open and Reproducible Research Training (FORRT)
Authors: Azevedo Flavio
Published: September 2022

The Framework for Open and Reproducible Research Training (FORRT) addresses the underappreciated pedagogical aspect of open and reproducible science and its associated challenges, including a need for curricular reform, an account of epistemological pluralism, the development of new methods of education, and questions around how open science practices relate to social justice and a principled academic education. Teachers’ and researchers’ time constraints are substantial, posing a challenge to developing course materials and integrating new research practices in teaching. FORRT has developed strategies and proposed solutions to mitigate time constraints and help scholars implement open and principled education in their workflows. FORRT’s e-learning platform is a hub for community-driven initiatives and resources. FORRT’s community conceptualized our educational Nexus as integrating diverse components into one infrastructure serving those wishing to learn, adopt, and disseminate open and reproducible science tenets. In this talk, we will explain each element of FORRT’s open educational resources, FORRT’s ethos and modus operandi.

Elements of the Nexus (https://forrt.org/nexus) are: FORRT’s Clusters (a pedagogically-driven organization of OS literature), Curated Resources (database of >1000 resources on OS), Initiatives Towards Social Justice in Academia (where we link mentees of unprivileged backgrounds to mentors of privileged ones), Open & Reproducible Science Summaries (having more than 300 summaries of OS literature), 7-ways to adopt principled teaching and mentoring practices (listing 100+ low commitment ways to interact with OS), Open & Reproducible Science Syllabus (a boiler-plate template for OS course that can be readily adapted and implemented in teachers’ courses), Self-Assessment Tool (a dynamic survey giving teachers feedback on how to integrate OS into their teaching), and finally, Educator’s Corner (offering a platform for educators of all stripes to share their stories, experiences, successes and hardships in teaching and mentoring, as well as for sharing educational practices and initiatives that are of interest to the OS community).
tidyqpcr
Authors: Haynes Sam , Wallace Edward
Published: September 2022

Software is intended to be a tool used to complete tasks efficiently. However, the intent is not always matched by the execution as users may become frustrated with design idiosyncrasies or suboptimal implementations. In order to support reproducibility and the user experience, research software needs to be rewarded on its usability and documentation as well as  its functionality. Quality documentation needs to cover design decisions, functionality, and how to contribute to the software. Here we describe our work to tackle the reproducibility crisis in qPCR analysis by creating the open-source software package tidyqpcr. We also introduced the extensive infrastructure available for creating software documentation in the R programming language. 

Quantitative polymerase chain reaction (qPCR) is a fundamental technique in molecular biology to detect and quantify DNA and RNA. However, the ubiquitous use of qPCR across research disciplines has led to inconsistencies in implementation and reporting, leading to a reproducibility crisis and the publication of the Minimum Information in a Quantitative PCR experiment (MIQE) guidelines. In addition, each stage of a qPCR experiment can be customised to extract a wide variety of information from numerous biological processes. Developing versatile and reliable software built with best-practices and thorough documentation would promote reproducible qPCR analysis across diverse disciplines. tidyqpcr is an open source software package for user-friendly qPCR analysis using the tidyverse suite of R packages. tidyqpcr offers a consistent user interface and structure for qPCR analysis, within the tidyverse paradigm of spreadsheet-like rectangular data frames and generic functions that build up complex analyses in a series of simple steps. tidyqpcr focuses on experimental design in microwell plates, and relative quantification using changes in quantification cycle (∆Cq). tidyqpcr has been improved in response to software review from the rOpenSci non-profit initiative, which co-ordinates with the Journal of Open Source Software. Overall, tidyqpcr empowers scientists to conduct reproducible, flexible, and best-practice compliant quantitative PCR analysis.
Analytical expression for approximation of the friction force of the vibration protection mechanism of the operator’s seat

Published: September 2022

In mathematical modeling of dynamic and vibration protection systems of operators of construction and road machines, it is necessary to take into account the damping properties of the mechanisms. Accounting for the friction force in mathematical models is often performed using a coefficient, according to the viscous friction model. In more complex models, it is common to use a well-known expression in which the functions of the exponent and hyperbolic tangent are present, and the independent parameters are the Coulomb and separation friction forces, the separation friction rate, and the coefficient of viscous friction. This expression is used in a well-known mathematical package. However, the well-known expression does not accurately approximate the experimental friction curves. In the present work, an alternative expression for the total friction force has been supplemented. The refinement made it possible to apply a new formula for the entire range of change in the velocity argument and more accurately reproduce the characteristic shape of the experimental friction characteristics. For the new expression, complementary formulas were obtained that establish the relationship between the input parameters and a number of others that have a clear and simple physical meaning of the parameters. A comparison was made of the generally accepted and proposed expressions according to experimental data, graphs of the relative error were constructed. Also, a comparison of two expressions of the total friction force was made, as an example, on a dynamic model of forced oscillations of a concentrated mass on a moving base. The comparison results showed a significant discrepancy between the generally accepted expression in comparison with the proposed one, in terms of the total friction force, as well as a discrepancy in the amplitudes of relative displacements and absolute mass accelerations obtained on the dynamic model. The proposed expression can be used to approximate the total friction force in mathematical models of dynamic vibration protection systems for operator seats.
Study of the dynamic behavior of a spool with a modernized drive
Authors:   National Research Tomsk Polytechnic University, Svojkin Andrey , Krauinsh Petr ,   National Research Tomsk Polytechnic University
Published: September 2022

This article discusses the dynamic behavior of a spool plunger with a modernized drive. Modernization of the drive consists in replacing the electromagnet with a stepper motor with the transformation of rotational motion, — with the help of a screw pair, — into a rectilinear one. The contact between the ends of the screw and the plunger is provided by a spring. The value of the preliminary compression of the plunger to the end of the screw is assigned on the basis of guaranteed operation without loss of contact, due to which the plunger practically does not respond to disturbances and is devoid of an oscillatory component during the transient process. The mathematical model includes the influence of fluid friction and hydrodynamic force arising from pressure loss on the distributor 4 MPa. The study of the dynamics of the plunger consists in the accelerated retraction of the screw — which is in force contact with the end face of the spool — and the determination of the limit values of acceleration as a function of the preload force.

Authors: Santos Kassandra Naely Rodrigues dos , Hoffmann Kunrath Milena
Published: September 2022

Este artigo tem por objetivo analisar a representação da sociedade de consumo e as relações comerciais, na Paris do final do século XIX, presentes no romance naturalista O Paraíso das Damas, publicado em 1883, pelo escritor francês Émile Zola. A temática central da narrativa aborda a propagação da sociedade de consumo através da ascensão e crescimento de uma grande loja de departamentos, Paraíso das Damas, que, inspirada em magazines parisienses reais do século XIX, transforma a organização do comércio local. Para isso, a pesquisa apoia-se nos conceitos teóricos de Colin Campbell (2001), sobre a romantização do consumo, de Jean Baudrillard (1995), que traz a organização dos signos de consumo e a evidência do excedente, de Pierre Bourdieu (2010), que aborda a teoria do sistema simbólico e organizacional do consumo, e Zygmunt Bauman (2008), que contribui com sua teoria da sociedade de consumo e a transformação dos sujeitos em mercadorias.

mortality in cancer care. This study was conducted to establish the
frequency of DIC in Zimbabwean breast cancer patients on doxorubicin and
to test the DIC predictive power of genetic biomarkers. METHODS A cohort
of 50 Zimbabwean breast cancer patients treated with doxorubicin were
followed up for 12 months with serial echocardiography and genotyped for
UGTA1A6*4, SLC28A3 and RARG. 11% of the patients experienced DIC.
RESULTS The frequency of SLC28A3 (rs7853758), UGT1A6*4 (rs17863783) and
RARG (rs2229774) was 60.7%, 17.9% and 14.3% respectively. No
association between DIC and the three variants was observed. CONCLUSIONS
This is the first study on the prevalence of DIC and associated genetic
biomarker predictive evaluation in Zimbabwean breast cancer patients.
The genetic frequencies observed in our study was different to that
reported in other populations. A larger sample size with a longer follow
up time will be necessary in future studies.
No longer a safe haven currency? A fresh evidence of Japanese yen under uncertainty
Authors: Lee Zheng-Zheng , Su Chi , Tao Ran
Published: September 2022

This paper aims to study the safe haven attribute of the Japanese yen under domestic and U.S. economic and policy uncertainty (EPU). Because of the existence of structural changes, a bootstrap rolling window subsample causality test is used to enhance the credibility of the results. The empirical results confirm that the exchange rate returns (RER) and Japanese EPU are correlated in specific periods when major economic or political events occur. In most crisis periods, the Japanese EPU has positive effects on RER, and the yen appreciates when the EPU is increasing. In addition, the RER of the yen and U.S. EPU are both negatively and positively connected. This finding confirms the hedging function of the yen in certain periods. The reason for this relationship is that Japan?s low interest rates make the yen the primary funding currency in speculative carrying trade strategies, and thus, it tends to appreciate during crisis periods regardless of the origins of the EPU shocks. Therefore, the yen can be held as a safe haven currency unless the government intervenes artificially.
Factors Associated With Discordant A1C-Estimated and Measured Average Glucose Among Hospitalized Patients With Diabetes

Published: September 2022

In this retrospective analysis, we explored the correlation between measured average glucose (mAG) and A1C-estimated average glucose (eAG) in hospitalized patients with diabetes and identified factors associated with discordant mAG and eAG at the transition from home to hospital. Having mAG lower than eAG was associated with Black race, other race, increasing length of stay, community hospital setting, surgery, fever, metformin use, certain inpatient diets, home antihyperglycemic treatment, and coded type 1 or type 2 diabetes. Having mAG higher than eAG was associated with certain discharge services (e.g., intensive care unit), higher BMI, hypertension, tachycardia, higher albumin, higher potassium, anemia, inpatient glucocorticoid use, and treatment with home insulin, secretagogues, and glucocorticoids. These factors should be considered when using patients’ A1C as an indicator of outpatient glycemic control to determine the inpatient antihyperglycemic regimens.

Aim

To explore whether there are racial/ethnic differences in diabetes management and outcomes among adult health center (HC) patients with type 2 diabetes.

Methods

We analyzed data from the 2014 Health Center Patient Survey, a national sample of HC patients. We examined indicators of diabetes monitoring (A1C testing, annual foot/eye doctor visits, and cholesterol checks) and care management (specialist referrals, individual treatment plan, and receipt of calls/appointments/home visits). We also examined diabetes-specific outcomes (blood glucose levels, diabetes-related emergency department [ED] visits/hospitalizations, and diabetes self-management confidence) and general outcomes (number of doctor visits, ED visits, and hospitalizations). We used multilevel logistic regression models to examine racial/ethnic disparities by the above indicators.

Results

We found racial/ethnic parity in A1C testing, eye doctor visits, and diabetes-specific outcomes. However, Hispanics/Latinos (odds ratio [OR] 0.26), non-Hispanic African Americans (OR 0.25), and Asians (OR 0.11) were less likely to receive a cholesterol check than Whites. Non-Hispanic African Americans (OR 0.43) were less likely to have frequent doctor visits, while Hispanic/Latino patients (OR 0.45) were less likely to receive an individual treatment plan.

Conclusion

HCs largely provide equitable diabetes care but have room for improvement in some indicators. Tailored efforts such as culturally competent care and health education for some racial/ethnic groups may be needed to improve diabetes management and outcomes.
Developing Priorities to Alleviate the Long-Term Impact of the COVID-19 Pandemic on Women Engaged in Diabetes Research, Education, and Care: A Concept Mapping Study

Objective

The aim of this study was to develop priorities through stakeholder engagement to alleviate the impact of the coronavirus disease 2019 (COVID-19) pandemic on the professional careers of women engaged in diabetes research, education, and care.

Research Design and Methods

This study used concept mapping, a mixed-methods, multistep process, to generate a conceptual map of recommendations through the following steps: 1) identify stakeholders and develop the focus prompt, 2) generate ideas through brainstorming, 3) structure ideas through sorting and rating on priority and likelihood, 4) analyze the data and create a cluster map, and 5) interpret and use results.

Results

Fifty-two participants completed the brainstorming phase, and 24 participated in sorting and rating. The final concept map included seven clusters. Those rated as highest priority were to ensure supportive workplace culture (μ = 4.43); promote practices to achieve gender parity in hiring, workload, and promotion (μ = 4.37); and increase funding opportunities and allow extensions (μ = 4.36).

Conclusion

This study identified recommendations for institutions to better support women engaged in diabetes-related work to alleviate the long-term impact of the COVID-19 pandemic on their careers. Some areas were rated as high in priority and high in likelihood, such as ensuring a supportive workplace culture. In contrast, family-friendly benefits and policies were rated as high in priority but low in likelihood of being implemented; these may take more effort to address, including coordinated efforts within institutions (e.g., women’s academic networks) and professional societies to promote standards and programs that advance gender equity in medicine.

Published: September 2022

The modern assessment of the state of the economy in the world has become widespread in the context of the systemic paradigm, according to which two aspects of the consideration of the economy can be distinguished: interaction of macroeconomics with the state and society; space-time continuum of different levels of the economy (micro-, meso- and macro levels). In terms of the ongoing global political contradictions, financial and economic crises, socio-ethnic conflicts, COVID-19 restrictions, the issues of in-depth understanding of sustainable mechanisms for economic development are of particular relevance, which involves the development of approaches and measures aimed at stable formation and development in small and medium-sized businesses (SMEs). The solutions are to be found and the scientific hypotheses expressed in assessing the features of the formation and development of small and medium-sized businesses in the Russian Federation are to be formed in the context of digital transformation of business processes. There is studied a wealth of patterns, which accompany various aspects of the formation and development of SMEs, taking into account the harmonization of the features of digital transformations in the field of economic, legal, socio-economic and accounting and analytical systems and tracks of their acceleration. The factors influencing the formation and development of SMEs are graphically interpreted, the main stages in the evolution of the formation of small and medium-sized businesses in the Russian Federation are characterized, and the problems, trends, prospects and main determinants of the features of the development of the object under study are identified through a content analysis and institutional, sociological and economic analysis. There has been worked out a concept of prospects for the development of digital transformation of SMEs including the four main areas (internal potential, adaptive business environment, availability of strategic resources, institutional regulation), which provide a faster transition to the new forms of organizing and running business.
