Biological nematicides as an alternative for control of Meloidogyne incognita populations in yellow
pitahaya (Sselenicereus megalanthus).
Authors: Vargas Yadira , Pico Jimmy , Manobanda Neiver , Garcia Angel , Sanmiguel Jessica
Published: March 2024

Yellow pitahaya in the Ecuadorian Amazon has become one of the most important economic crops in the
region. However, pests (nematodes) in the soil have affected up to 100% of the crop's growth stages. Faced
with this problem, growers use various chemical nematicides that minimize this impact but cause
contamination problems. For this reason, the objective of the research was to evaluate microorganisms that
control or reduce the population of Meloidogyne incognita in the pitahaya crop at the greenhouse level. The
design was DBCA, and the statistical analysis was performed with the statistical package Infostat 2017, using
linear mixed models and Fisher's tests at 5%. The results show that root nodules decrease when P. lilacinum
+ T. asperellum is applied after nematode injection (261). In addition, the lowest number of nodulations (251)
was obtained when microorganisms were applied after nematode inoculation (251 nodulations). Still, when
microorganisms were used before, aerial biomass growth was stimulated (384.17 g) even when nematodes
were present in the root system.

Digital Health Interventions in Older Adult Populations Living With Chronic Disease in High-Income Countries: Protocol for a Scoping Review (Preprint)
Authors: Ashraf Mir Nabila , Gallant Natasha L , Bradley Cara
Published: March 2024

BACKGROUND

Globally, around 80% percent of adults aged 65 years or older are living with at least 1 chronic disease, and 68% percent have 2 or more chronic diseases. Older adults living with chronic diseases require greater health care services, but these health care services are not always easily accessible. Furthermore, the COVID-19 pandemic has resulted in unprecedented changes in the provision of health care services for older adults. During the COVID-19 pandemic, digital health interventions for chronic disease management were developed out of necessity, but the evidence regarding these and developed interventions is lacking.

OBJECTIVE

In this scoping review, we aim to identify available digital health interventions such as emails, text messages, voice messages, telephone calls, video calls, mobile apps, and web-based platforms for chronic disease management for older adults in high-income countries.

METHODS

We will follow the Arksey and O’Malley framework to conduct the scoping review. Our full search strategy was developed following a preliminary search on MEDLINE. We will include studies where older adults are at least 65 years of age, living with at least 1 chronic disease (eg, cancer, cardiovascular disease, chronic obstructive pulmonary disease, and diabetes), and residing in high-income countries. Digital health interventions will be broadly defined to include emails, text messages, voice messages, telephone calls, video calls, mobile apps, and web-based platforms.

RESULTS

This scoping review is currently ongoing. As of March 2023, our full search strategy has resulted in a total of 9901 records. We completed the screening of titles and abstracts and obtained 442 abstracts for full-text review. We are aiming to complete our full-text review in October 2024, data extraction in November 2024, and data synthesis in December 2024.

CONCLUSIONS

This scoping review will generate evidence that will contribute to the further development of digital health interventions for future chronic disease management among older adults in high-income countries. More evidence-based research is needed to better understand the feasibility and limitations associated with the use of digital health interventions for this population. These evidence-based findings can then be disseminated to decision-makers and policy makers in other high-income countries.

Impact of an Electronic Health Record based Interruptive Alert among Patients with Headaches seen in Primary Care: A Cluster Randomized Controlled Trial (Preprint)
Authors: Pradhan Apoorva , Wright Eric A. , Hayduk Vanessa A. , Berhane Juliana , Sponenberg Mallory , Webster Leeann , Anderson Hannah , Park Siyeon , Graham Jove , Friedenberg Scott
Published: March 2024

BACKGROUND

Headaches including migraines are one of the most common causes of disability and account for nearly 20-30% of referrals from primary care to neurology. Electronic health record-based alerts have been used in the past within primary care with varying degree of success to influence provider behaviors in multiple disease states except for headaches.

OBJECTIVE

The aim of this project was to evaluate the impact of an electronic alert implemented in primary care on patients’ overall headache management.

METHODS

We conducted a stratified cluster-randomized study across 38 primary care clinic sites between December 2021 to December 2022 at a large integrated healthcare delivery system in the United States. Clinics were stratified into six blocks based on region and patient-to-provider ratios and then 1:1 randomized within each block into either control or intervention. Providers practicing at intervention clinics received an interruptive alert in the electronic health record. The primary endpoint was a change in headache burden, measured using the Headache Impact Test 6 (HIT-6) scale, from baseline to six months. Secondary outcomes included change in headache frequency and intensity, access to care, and resource utilization. The analysis was performed to assess the difference in difference outcomes between the arms at follow up at the individual patient level.

RESULTS

We enrolled 203 adult patients with a confirmed headache diagnosis. At baseline the average HIT-6 scores (standard deviation) in each arm were not significantly different (Intervention – 63 (+- 6.9) vs. Control - 61.8 (+- 6.6), P= .21). We observed a significant reduction in the headache burden only in the intervention arm at follow-up (3.5-point, P= .009). The reduction in the headache burden was not statistically different between groups (difference-in-difference estimate: -1.89 (95% confidence interval -5.0, 1.31; P= .25). Similarly, secondary outcomes were not significantly different between groups. Only 11% of alerts were acted upon.

CONCLUSIONS

The use of an interruptive electronic alert did not significantly improve headache outcomes. Low use of alerts by providers prompts future alterations of the alert and exploration of alternative approaches.

Decades in the Making: The Evolution of Digital Health Research Infrastructure Through Synthetic Data, Common Data Models, and Federated Learning (Preprint)
Authors: Austin Jodie A , Lobo Elton H , Samadbeik Mahnaz , Engstrom Teyl , Philip Reji , Pole Jason D , Sullivan Clair M
Published: March 2024

UNSTRUCTURED

Traditionally, medical research is based on randomized controlled trials (RCTs) for interventions such as drugs and operative procedures. However, increasingly, there is a need for health research to evolve. RCTs are expensive to run, are generally formulated with a single research question in mind, and analyze a limited dataset for a restricted period. Progressively, health decision makers are focusing on real-world data (RWD) to deliver large-scale longitudinal insights that are actionable. RWD are collected as part of routine care in real time using digital health infrastructure. For example, understanding the effectiveness of an intervention could be enhanced by combining evidence from RCTs with RWD, providing insights into long-term outcomes in real-life situations. Clinicians and researchers struggle in the digital era to harness RWD for digital health research in an efficient and ethically and morally appropriate manner. This struggle encompasses challenges such as ensuring data quality, integrating diverse sources, establishing governance policies, ensuring regulatory compliance, developing analytical capabilities, and translating insights into actionable strategies. The same way that drug trials require infrastructure to support their conduct, digital health also necessitates new and disruptive research data infrastructure. Novel methods such as common data models, federated learning, and synthetic data generation are emerging to enhance the utility of research using RWD, which are often siloed across health systems. A continued focus on data privacy and ethical compliance remains. The past 25 years have seen a notable shift from an emphasis on RCTs as the only source of practice-guiding clinical evidence to the inclusion of modern-day methods harnessing RWD. This paper describes the evolution of synthetic data, common data models, and federated learning supported by strong cross-sector collaboration to support digital health research. Lessons learned are offered as a model for other jurisdictions with similar RWD infrastructure requirements.
Co-Design of an Escape Room for e-Mental Health Training of Mental Health Care Professionals: Research Through Design Study (Preprint)
Authors: Bierbooms Joyce J P A , Sluis-Thiescheffer Wouter R J W , Feijt Milou Anne , Bongers Inge M B
Published: March 2024

BACKGROUND

Many efforts to increase the uptake of e-mental health (eMH) have failed due to a lack of knowledge and skills, particularly among professionals. To train health care professionals in technology, serious gaming concepts such as educational escape rooms are increasingly used, which could also possibly be used in mental health care. However, such serious-game concepts are scarcely available for eMH training for mental health care professionals.

OBJECTIVE

This study aims to co-design an escape room for training mental health care professionals’ eMH skills and test the escape room’s usability by exploring their experiences with this concept as a training method.

METHODS

This project used a research through design approach with 3 design stages. In the first stage, the purpose, expectations, and storylines for the escape room were formulated in 2 co-design sessions with mental health care professionals, game designers, innovation staff, and researchers. In the second stage, the results were translated into the first escape room, which was tested in 3 sessions, including one web version of the escape room. In the third stage, the escape room was tested with mental health care professionals outside the co-design team. First, 2 test sessions took place, followed by 3 field study sessions. In the field study sessions, a questionnaire was used in combination with focus groups to assess the usability of the escape room for eMH training in practice.

RESULTS

An escape room prototype was iteratively developed and tested by the co-design team, which delivered multiple suggestions for adaptations that were assimilated in each next version of the prototype. The field study showed that the escape room creates a positive mindset toward eMH. The suitability of the escape room to explore the possibilities of eMH was rated 4.7 out of 5 by the professionals who participated in the field study. In addition, it was found to be fun and educational at the same time, scoring 4.7 (SD 0.68) on a 5-point scale. Attention should be paid to the game’s complexity, credibility, and flexibility. This is important for the usefulness of the escape room in clinical practice, which was rated an average of 3.8 (SD 0.77) on a 5-point scale. Finally, implementation challenges should be addressed, including organizational policy and stimulation of eMH training.

CONCLUSIONS

We can conclude that the perceived usability of an escape room for training mental health care professionals in eMH skills is promising. However, it requires additional effort to transfer the learnings into mental health care professionals’ clinical practice. A straightforward implementation plan and testing the effectiveness of an escape room on skill enhancement in mental health care professionals are essential next steps to reach sustainable goals.

Published: March 2024

Cash holdings, or the amount of cash and cash equivalents a company holds, become more significant when economic uncertainty increases. Reddaway (1936) argued that cash holdings serve transactional, precautionary, and speculative purposes, underscoring their importance, particularly during economic downturns. This pandemic has encouraged companies to manage their financial resources carefully. This research explores the impact of the COVID-19 pandemic on cash holdings in consumer goods companies across the initial three years of the pandemic. Data were sourced from the Wall Street Journal Database (WSJ), spanning 2018 to 2022. Utilizing the fixed effects model (FEM), the analysis encompasses a dataset of 1.491 companies from 80 countries. The findings indicate a substantial and positive correlation between the COVID-19 pandemic and cash holdings within the consumer goods sector. This effect is pronounced in the first, second, and third years of the pandemic, highlighting companies’ decisions to bolster cash reserves as a response to pandemic-induced uncertainty. This analysis underscores the widespread influence of the COVID-19 pandemic on cash holdings across industries, market types, and geographical regions.

Published: March 2024

This study aimed to investigate the importance of art museum and its influence on behavioural intention of visitors. Well-structured questionnaire directed at two hundred visitors who were willing to participate in the study was used to gather data for analysis. Data was analyzed descriptively through tables, charts and inferentially through Chi Square and Pearson correlation. Results revealed that “I gained new knowledge from my experience visiting art museum” had the highest mean value (4.21) of perception about art museums. Also, the visitors were willing to visit more art museums and they were satisfied with the art museum visited. Furthermore, hypothesis revealed that there is a significant relationship between satisfaction of the visitors and their behavioural intention towards art museums. Therefore, art museums should be promoted more since they serve as educative and entertaining means of promoting knowledge or art exhibits and local culture of the populace.

Today, the most common domestic electric equipment is a household refrigerator. The use of flammable substances as refrigerants for refrigerators can lead to severe consequences. As the production of hydrofluorocarbon class refrigerants for refrigeration equipment was restricted by the Kigali amendment to the Montreal Protocol, refrigeration technologies have been transferred from using hydrofluorocarbon class refrigerants to natural refrigerants (propane, butane, isobutane). The replacement of hydrofluorocarbon class refrigerants with natural refrigerants is already noticeable since in many cases isobutane (R-600a) is used as a refrigerant for refrigeration equipment. Isobutane is a combustible substance with a wide explosion limit (1.8–9.5 % vol.); hence, it is classified as an A2 refrigerant class of hazard (combustible substances). As R-600a is classified as an A2 class of fire hazard, its use in refrigeration technologies is limited with the refrigerant mass; therefore, the use of R-600a for refrigeration equipment is considered safe. According to international and Russian data, however, some accidents involving the use of flammable refrigerants in refrigeration equipment were registered. In the US, two explosions of serviceable household refrigerators were registered; in the Russian Federation, one explosion of refrigeration equipment during repair jobs was registered. According to the parameters of refrigeration equipment explosion, R-600а was used as a refrigerant. This study provides a calculation of excess pressure of explosion in case of leakage of R-600a from a refrigerator in the volume of a living accommodation (kitchen) in order to estimate the fire safety of combustible refrigerants. Based on the results of calculations, it has been concluded that the existing norms of the use of combustible refrigerants are insufficient and cannot ensure fire-explosion and fire safety for a person and refrigeration equipment.
Aerodynamic Noise Muffler for Industrial Artificial Weather Apparatuses
Authors:   Togliatti State University, Krasnov A.V.
Published: March 2024

Increased levels of aerodynamic noise are specific to many industrial production workflows. Artificial weather apparatuses (AWP) installed in production workshops and labs can be significant sources of aerodynamic noise. According to the measurement results, the sound level in the premises where artificial weather apparatuses are installed may reach 86–90 dBA. At the same time, the spectrum of noise emission is broadband, whereas the highest-level values are within the range of frequencies 200–10,000 Hz. The study's objective is to design a combined noise muffler that ensures the efficient reduction of aerodynamic noise of air intake and exhaust caused by artificial weather apparatuses in a broad range of frequencies. The proposed design of the noise muffler contains two isolated from each other chambers that ensure the reduction of air intake and exhaust noise. The chambers of the artificial weather apparatus are connected with inlet and outlet windows via air ducts. The air is sucked into the inlet chamber and removed from the outlet chamber via pipes. Partitions partially overlapping the chambers’ cross-section are installed inside the chambers. Perforated flow dividers are installed in the air ducts and pipes. Noise muffler elements are made of polymer material. Surfaces of elements installed inside the chambers are lined with porous sound-absorbing material containing open-cell polyurethane foam and a protective coating of sound-transparent, gas- and moisture-impermeable film. Sections of air ducts and pipes in chamber cavities are located at a certain distance from the surface of internal walls. The results of calculations of reactive and dissipative efficiency of one of the designs of the proposed noise muffler are provided. The efficiency of the application of the noise muffler developed is confirmed by the results of measurements of the sound level of the artificial weather apparatus in the production lab. The overall sound level before the noise muffler installation was 86 dBA, with broadband spectrum with tonal components. The installation of the noise muffler enabled the reduction of sound levels in the premises by 17–34 dBA in the broad range of frequencies 200–20,000 Hz.
Ensuring Seismic Safety of Construction Objects during Open-Pit Mine Blasts, Considering Limit States of the First Group

In certain situations, seismic safety during open-pit mine blasts can be ensured only on the condition of coordination of the explosion technology regulatory documents with the provisions of the construction field regulatory documents. The distinctive feature of the construction documents is the application of probabilistic approaches to load specification. The limit state method is used to calculate the structures. The probability of non-exceeding the design values of the main loads is adopted as not less than 0.98 for the calculations of the first group of limit states. The explosion technology regulatory documents take into account the second group limit states at which the operation of protected objects is possible but hampered, for example, as a result of the increased frequency of objects’ repairs. At the same time, the probability of minor damages is 0.9–0.95. The methodology to ensure the seismic safety of protected objects during open-pit mine blasts, based on regression analysis of the experimental data and considering the probabilistic nature of such effects, is presented. The methodology considers all features of explosion technology applied at a given enterprise, as well as the structure of the geological environment along the way of seismic wave propagation, and other factors. Despite many advantages, however, the probabilistic approaches limit the minimum number of experimental points required to build a regression line and the limits of confidence intervals. Therefore, the increase in the confidence level of peak particle velocity from 0.95 to 0.98 must be accompanied by the increase in the minimum number of experimental points used to build the regression from 80 to 200, which significantly increases the scope and cost of the required experimental studies. The article considers the possibility of an increase in the confidence level of peak particle velocity caused by open-pit mine blasts from 0.95 to 0.98 without increasing the volume of the experimental sample; the conditions under which it becomes possible are analyzed as well.

Published: March 2024

The issues of identification of environmental hazards when implementing the concept of the involvement of poor metal-containing raw materials and tailings from ore processing through the application of a new leaching technology with a detailed version of heap leaching on the earth have been considered. The methodology of identification of the environmental consequences of the implementation of the technology of deep processing of non-conventional mineral raw materials considering the impact of mineral waste on the environment of the field development region has been formulated. An environmental component of the complex ecological and economic effect comprised of the consistently implemented stages of the existence of the enterprise has been considered. The main factors of negative environmental impact received a quantitative assessment; the territories adjacent to the enterprise have been ranked by the degree of the anthropogenic impact. The options to determine the extent of damage caused by the contamination of ecosystems with heavy metals have been proposed. Models to determine the environmental damage caused by industrial effluents as the main transporting medium and the efficiency of utilization of substandard raw materials based on the profit criterion have been formulated. The mechanism of removal of reagents and solutions to the environment by airflows has been specified. An approximate calculation of parameters of the environmental contamination for ore leaching of ore raw materials in the Sadonskoye deposit has been provided. It has been demonstrated that the chemical contamination of soils is prioritized when determining the environmental hazard and the hazard for the enterprise employees. It has been proved that the combined ecological and economic model of assessment of the efficiency of utilization of substandard raw materials joins ecological and economic aspects within a single natural and anthropogenic system, whereas the ecological and economic efficiency of production is a function of integrating methods of field development, including the application of a safety criterion for ecosystems of the environment. The study results can be used for the adjustment to the legislation on mining in the Russian Federation.

The article is dedicated to the research and development of the ammonium-perchlorate-based pyrotechnic composition used for the safe destruction of artificial concrete objects. Ammonium perchlorate has been used as an oxidant of the pyrotechnic composition. Primarily, this is conditioned by the powerfully destructive force of ammonium perchlorate; the application of perchlorate compounds enables obtaining the most energy-efficient compositions. The magnesium powder brand MPF-1 has been used as a fuel and the polyethylene as a fuel and gas-forming agent. The impacts of different amounts of magnesium powder on the properties of combustion of the ammonium-perchlorate-based pyrotechnic composition have been studied. The calculation and experimental data have shown that it is impractical to introduce more than 5 % of magnesium into the composition. Based on the study results, the ammonium-perchlorate-based pyrotechnic composition was elaborated in order to increase the efficiency and safety of blast jobs. The laboratory and landfill tests have confirmed the efficiency and safety of the use of pyrotechnic compositions for the destruction of artificial concrete objects. A concrete block was destroyed without the scattering of fragments and the formation and propagation of a blast airwave. Therefore, ensuring the safety of blast jobs involving pyrotechnic compositions is a first-priority task, which will prevent the generation of harmful and poisonous gases and the brisant action of explosion.

Анализ динамики заболеваемости ожирением среди населения трудоспособного возраста за 10 лет на примере Саратовского региона.
Authors: Долич Владимир
Published: March 2024

Введение. Ожирение имеет крайне высокий уровень социальной и экономической значимости среди лиц трудоспособного возраста, так как сопровождается глобальным экономическим ущербом для всего государства, что обусловлено значимым вкладом ожирения в развитие других хронических неинфекционных заболеваний, включая ишемическую болезнь сердца, являющуюся самой распространенной причиной преждевременной смертности во всем мире. Материалы и методы. Проанализированы показатели общей и первичной заболеваемости ожирением среди населения трудоспособного возраста на территории Саратовской области в динамике за 10 лет (2013-2022 гг.). Показатели заболеваемости ожирением сопоставлены с общей и первичной заболеваемостью ишемической болезнью сердца в Саратове и районах Саратовской области. На основании данных Государственного учреждения здравоохранения «Медицинский информационно-аналитический центр» Саратова проведен анализ распределения муниципальных образований по коэффициенту обеспеченности медицинскими кадрами. Результаты. В период с 2013 по 2022 гг. показатель общей заболеваемости ожирением по Саратову увеличился на 6,8%, по Саратовской области – на 22,2%; показатель первичной заболеваемости увеличился на 53,3% и на 81,4% соответственно. Наибольшее количество районов Саратовской области имеют низкий и крайне низкий коэффициент обеспеченности медицинскими кадрами. Темпы роста общей и первичной заболеваемостью ишемической болезнью сердца многократно превышают заболеваемость ожирением в большинстве районов Саратовской области, включая те, в которых отмечается снижение показателя общей заболеваемости ожирением. Ограничение исследования. Исследование имеет региональные (Саратовская область) ограничения. Заключение. Результаты проведенного исследования свидетельствуют о росте общей и первичной заболеваемости ожирением на территории Саратова и Саратовской области с 2013 по 2022 гг. На территории районов Саратовской области отмечается разнонаправленная тенденция распространенности ожирения за десятилетний период. Из полученных данных можно сделать предположение, что на территории Саратовской области отмечается недостаточный уровень диагностики ожирения.

Objectives: This study was conducted to assess the efficacy of nirmatrelvir/ritonavir treatment in patients with coronavirus disease 2019 (COVID-19), particularly those aged 60 years and older. Using real-world data, the period during which the BN.1 Omicron variant was dominant was compared to the period dominated by the BA.5 variant.Methods: In this retrospective cohort study, data were collected regarding 2,665,281 patients infected with severe acute respiratory syndrome coronavirus 2 between July 24, 2022, and March 31, 2023. Propensity score matching was utilized to match patients who received nirmatrelvir/ritonavir in a 1:4 ratio between BN.1 and BA.5 variant groups. Multivariable logistic regression analysis was employed to assess the effects of nirmatrelvir/ritonavir within these groups.Results: Compared to the prior period, the efficacy of nirmatrelvir/ritonavir did not significantly differ during the interval of Omicron BN.1 variant dominance in the Republic of Korea. Among patients treated with nirmatrelvir/ritonavir, a significantly lower risk of mortality was observed in the BN.1 group (odds ratio [OR], 0.698; 95% confidence interval [CI], 0.557–0.875) compared to the BA.5 group. However, this treatment did not significantly reduce the risk of severe or critical illness, including death, for those in the BN.1 group (OR, 0.856; 95% CI, 0.728–1.007).Conclusion: Nirmatrelvir/ritonavir has maintained its effectiveness against COVID-19, even with the emergence of the BN.1 Omicron subvariant. Consequently, we strongly recommend the administration of nirmatrelvir/ritonavir to patients exhibiting COVID-19-related symptoms, irrespective of the dominant Omicron variant or their vaccination status, to mitigate disease severity and decrease the risk of mortality.

Published: March 2024

Modern societies strive for greater gender equality and inclusivity, so it is crucial to study the impact of gender on career guidance in order to develop more effective interventions and support systems. Recognizing the uniqueness of the problem and experience faced by people of different genders can increase the effectiveness and relevance of career guidance activities. By studying various aspects of career growth through a gender lens, science contributes to a better understanding of how gender shapes career choices, experiences, and counseling needs of individuals. The article examines the features of professional choice and career building from the perspective of gender theories. It is concluded  that they help to explain the formation and strengthening of gender stereotypes, the impact of discrimination on psychological well–being, choice of profession and career trajectory, as well as the interaction of gender with other social identities.
