Published: October 2021

Background

The COVID-19 global pandemic has increased the burden of mental illness on Canadian adults. However, the complex combination of demographic, economic, and lifestyle factors and perceived health risks contributing to patterns of anxiety and depression has not been explored.

Objective

The aim of this study is to harness flexible machine learning methods to identify constellations of factors related to symptoms of mental illness and to understand their changes over time during the COVID-19 pandemic.

Methods

Cross-sectional samples of Canadian adults (aged ≥18 years) completed web-based surveys in 6 waves from May to December 2020 (N=6021), and quota sampling strategies were used to match the English-speaking Canadian population in age, gender, and region. The surveys measured anxiety and depression symptoms, sociodemographic characteristics, substance use, and perceived COVID-19 risks and worries. First, principal component analysis was used to condense highly comorbid anxiety and depression symptoms into a single data-driven measure of emotional distress. Second, eXtreme Gradient Boosting (XGBoost), a machine learning algorithm that can model nonlinear and interactive relationships, was used to regress this measure on all included explanatory variables. Variable importance and effects across time were explored using SHapley Additive exPlanations (SHAP).

Results

Principal component analysis of responses to 9 anxiety and depression questions on an ordinal scale revealed a primary latent factor, termed “emotional distress,” that explained 76% of the variation in all 9 measures. Our XGBoost model explained a substantial proportion of variance in emotional distress (r2=0.39). The 3 most important items predicting elevated emotional distress were increased worries about finances (SHAP=0.17), worries about getting COVID-19 (SHAP=0.17), and younger age (SHAP=0.13). Hopefulness was associated with emotional distress and moderated the impacts of several other factors. Predicted emotional distress exhibited a nonlinear pattern over time, with the highest predicted symptoms in May and November and the lowest in June.

Conclusions

Our results highlight factors that may exacerbate emotional distress during the current pandemic and possible future pandemics, including a role of hopefulness in moderating distressing effects of other factors. The pandemic disproportionately affected emotional distress among younger adults and those economically impacted.
The Acceptability of Digital Technology and Tele-Exercise in the Age of COVID-19: Cross-sectional Study (Preprint)
Authors: Ho Vanda , Merchant Reshma A
Published: October 2021

BACKGROUND

With the COVID-19 pandemic, telehealth has been increasingly used to offset the negative outcomes of social isolation and functional decline in older adults. Crucial to the success of telehealth is end user adoption.

OBJECTIVE

This study aims to investigate perception and acceptability of digital technology among Asian older adults.

METHODS

The Healthy Ageing Promotion Program for You (HAPPY) dual-task exercise was conducted virtually to participants aged ≥60 years. Questionnaires were administered digitally and collected data on demographics, perceptions of digital technology and evaluation of HAPPY, the 6-item Lubben Social Network Scale, intrinsic capacity using the Integrated Care for Older People tool, and a functional screening with the FRAIL scale and five chair rises. Descriptive analysis was used.

RESULTS

A total of 42 participants were digitally interviewed. The mean age was 69.1 (4.7) years. Hearing, vision, and 3-item recall difficulty were present in 14% (n=6), 12% (n=5), and 24% (n=10) of participants, respectively. Of the participants, 29% (n=12) had possible sarcopenia and 14% (n=6) were prefrail. Around 24% (n=10) were at risk of social isolation. Most of the participants (n=38, 91%) agreed that technology is good, and 79% (n=33) agreed that technology would allow them to be independent for longer. Over three-quarters of participants (n=33, 79%) agreed that they have the necessary knowledge, and 91% (n=38) had technological assistance available. However, 57% (n=24) were still apprehensive about using technology. Despite 71% (n=30) of older adults owning their devices, 36% (n=15) felt finances were limiting. Through digital HAPPY, 45% (n=19) of participants reported feeling stronger, 48% (n=20) had improved spirits, and 40% (n=17) and 38% (n=16) had improved mood and memory, respectively.

CONCLUSIONS

The majority of older adults in this study believed in digital technology and had the necessary knowledge and help, but almost half still felt apprehensive and had financial barriers to adopting technology. A digitally administered exercise program especially in a group setting is a feasible option to enhance intrinsic capacity in older adults. However, more work is needed in elucidating sources of apprehension and financial barriers to adopting technology.

Molecular classification of endometrial carcinoma: protocol for a cohort study (Preprint)
Authors: Moreira Inês , Bartosch Carla , Teixeira Manuel , Ferreira Marta
Published: October 2021

UNSTRUCTURED

Endometrial carcinoma (EC) is the most common gynaecologic malignancy in developed countries and the fourth most frequent in women worldwide. Incidence of EC has been increasing in the past several years, mainly due to increasing rates of metabolic syndrome.
The cornerstone of treatment for EC is surgery. Clinicopathological features are currently used to help determine the individual risk of recurrence and the need for adjuvant treatment after surgery. Nonetheless, there is a significant inter-observer variability in assigning histologic subtype when using a morphological classification, revealing the need for a more unified approach.
The Cancer Genome Atlas (TCGA) project identified four distinct prognostic EC subtypes based on genomic abnormalities. Surrogate assays including three immunohistochemical markers (p53, MSH6 and PMS2) and one molecular test (mutation analysis of the exonuclease domain of POLE), allowed the development and validation of a simplified molecular classifier that correlates with the TCGA classification, has prognostic value and can easily be used in clinical practice. This molecular classification categorizes EC in 4 subtypes: POLE mutated, mismatch repair deficient, p53 abnormal and no specific molecular profile. Applying this classification in clinical practice will help tailor adjuvant treatment decisions.
The aim of this study is to retrospectively apply this novel molecular classification on a cohort of EC patients treated in a comprehensive cancer centre, to assess its applicability in clinical practice, to evaluate clinical outcomes by molecular subtypes and assess its prognostic value.

A Systematic Review on Nerve Chemical Warfare Agents
Authors: R Gagan
Published: October 2021

Abstract: The recent poisoning of Russian opposition figure and critic Alexei Navalny on August 20th , 2020 with a Soviet-era Novichok nerve agent reminded the world of the use of chemical agents, especially nerve agents to eliminate individual targets or for mass destruction. Nerve agents are a class of organophosphorus compounds. Soman, Sarin, Tabun, Cyclosarin, VX are a few examples of nerve agents. Nerve agents affect a person by disrupting the mechanism by which nerve signals are passed in the body. They inhibit the action of acetylcholinesterase enzyme which is responsible for the breakdown of acetylcholine neurotransmitters leading to accumulation of acetylcholine in the body. Nerve agents have a range of chemical effects on the eye, gastro-intestinal (GI) tract, Central nervous system (CNS), Respiratory system, Cardiovascular system and Neurological system. The management of nerve agent poisoning is done by administering Atropine or Pralidoxime chloride or also by administering anticonvulsants like Benzodiazepines or Diazepam. This review presents all such detailed information on this class of chemical Warfare agents. Keywords: Chemical Warfare Weapon, Nerve Agents, Acetylcholinesterase, Toxicity, Instrumentation

Published: October 2021

The features of Russia is the low population density on huge, poorly developed lands in terms of production. About 20 million people live in the territory where there is no centralized power supply, power supply is organized on generating systems running on imported fuel. (Research purpose) The research purpose is in studying the prospects for the development of microgrids based on the use of alternative energy generating systems of renewable energy sources using a micro-gas turbine plant as the base generator, which is the source of the reference voltage of microgrid based on single-wire resonant distribution networks of a new generation in Russia. (Materials and methods) The article presents the prospects for the development of microgrids based on material taken from open sources. Authors applied the methods of scientific analysis of events, facts, materials, and conclusions. (Results and discussions) The article shows that the world energy system evolutionarily enters a new fourth stage of fundamental transformation, called the "Energy Transition". The creation of microgrids based on renewable energy sources with a basic micro-gas turbine unit and single-wire resonant distribution networks of a new generation is an indisputable proof of this energy transition. (Conclusions) In many countries of the world, there is an increase in the share of distributed generation based on renewable energy sources, the introduction of new centralized generation capacities is reduced, investments in the construction of large power plants and new high-voltage transmission lines are reduced due to the development of distributed generation. Distributed generation contributes to the rapid expansion of electricity production without the need for additional development of the power grid infrastructure.

Published: October 2021

The grain industry is an important branch of agriculture. It is directly related to the harvesting, transportation, storage and processing of grain. To ensure the high quality of grain bulk products, there are currently used various electrotechnological grain cleaning plants. The most modern and effective are optoelectronic grain sort-ers (photo separators). However, there are a number of technological and structural disadvantages that reduce the efficiency of separating the grain mass into fractions and the performance of photo separators. That is why the problem of increasing the efficiency of optoelectronic installations for sorting agricultural grain products is urgent. (Research purpose) The research purpose is in development of an electrotechnological optoelectronic installation with justification of the parameters and modes of its operation. (Materials and methods) The development of an optoelectronic system for sorting agricultural grain products was carried out in accordance with the theoretical laws of mechanics, electrical engineering and optics, as well as on the basis of the norms and requirements of GOST for grain products. Testing of the efficiency of this unit was carried out on the basis of a laboratory unit in the Kuban State Agrarian University. The reliability of the results is confirmed by the repeated repetition of the conducted studies and the reproducibility of the obtained results, the use of generally accepted methods, devices, and mathematical processing of experimental data. (Results and discussion) The article presents the technological scheme and technical characteristics of the optoelectronic installation for the analysis and sorting of agricultural grain products, and parameters and modes of its operation. The main elements of this installation are: feed conveyors and an electromagnetic drum that provide a piecebypiece supply of seeds to the analysis zone, an optical unit of cameras for obtaining a threedimensional image of seeds, an executive unit for the rejection of grain products (pneumatic ejectors).

When performing various technological operations in crop production, the working bodies of tillage equipment in contact with the soil wear out under the influence of an abrasive environment. (Research purpose) The research purpose is in theoretical substantiation for a method for quantifying the wear capacity of soils with different abrasive characteristics. (Materials and methods) The article presents the evaluation of the abrasive ability of the soil by the wear of a steel rod vertically immersed in the soil and moving translationally. Authors used the standard rod of steel St0; geometric parameters of the worn rod are diameter d = 25-30 millimeters, height h = 250 millimeters; dynamic characteristics during the test are moving speed V = 3 kilometers per hour, distance of movement L = 100 meters. The worn rod sinks to a certain depth, moves in the soil at a constant speed. A device was used to determine the abrasive characteristics of the soil. (Results and discussion) The numerical characteristic of the wear capacity of the soil was determined as the physical value of the wear of the standard worn rod when moving in the soil as A=Q/L, grams per meter. The lower the value of this ratio, the less abrasive components are in the soil; based on the wear data of a standard rod, it is possible to obtain a characteristic of the wear capacity of various soils. (Conclusions) The proposed method allows us to determine the abrasive and wear characteristics of various types of soils. The results of the study make it possible to install working bodies on tillage machines in accordance with the type and wear capacity of the soil in which they will work, which will reduce the cost of their manufacture and increase the efficiency of the use of equipment.
Quantum Advantage for Shared Randomness Generation

Published: October 2021

Sharing correlated random variables is a resource for a number of information theoretic tasks such as privacy amplification, simultaneous message passing, secret sharing and many more. In this article, we show that to establish such a resource called shared randomness, quantum systems provide an advantage over their classical counterpart. Precisely, we show that appropriate albeit fixed measurements on a shared two-qubit state can generate correlations which cannot be obtained from any possible state on two classical bits. In a resource theoretic set-up, this feature of quantum systems can be interpreted as an advantage in winning a two players co-operative game, which we call the `non-monopolize social subsidy' game. It turns out that the quantum states leading to the desired advantage must possess non-classicality in the form of quantum discord. On the other hand, while distributing such sources of shared randomness between two parties via noisy channels, quantum channels with zero capacity as well as with classical capacity strictly less than unity perform more efficiently than the perfect classical channel. Protocols presented here are noise-robust and hence should be realizable with state-of-the-art quantum devices.

Authors: Kim Minseo , Jeon Sungmi , Kim Sang Wha
Published: October 2021

Pressure sores are common but troublesome for both patients and clinicians. They can range from mild to severe and must be managed accordingly. Despite advancements in both non-surgical and surgical intervention, no standard treatment protocol has yet been established. Since pressure sores can occur in a variety of clinical settings, treatment must be individualized to the patient’s circumstances. Recently, acellular dermal matrix (ADM) has been utilized as an alternative treatment for non-healing wounds. In the present report, we describe the case of a non-ambulatory patient in whom a large pressure sore located near the anus was completely cured using CG paste, an injectable ADM.

Authors: Kim Jinhyun , Kim Taewoon , Eun Seokchan
Published: October 2021

Necrotizing fasciitis of the lower extremities results in large tissue defects, and most cases require reconstruction using skin grafts or flaps. We describe a 61-year-old man who developed necrotizing fasciitis of the right lower leg and septic shock, following a traumatic injury to his leg. Wound culture yielded methicillin-resistant Staphylococcus aureus. Extensive debridement was performed four times along with the use of appropriate antibiotics. After 2 weeks, physical examination showed an open wound (approximately 30×20 cm in size) with partial tibial bone exposure. Subsequently, the patient underwent successful reconstruction using a tibialis anterior musculofascial flap and split-thickness skin grafting. The tibialis anterior muscle was bihalved and pivoted to cover the exposed bone surface. The patient was without pain and was able to successfully perform daily activities at the 15-month follow-up. This case report highlights the utility of a bihalved tibialis anterior musculofascial flap for lower extremity reconstruction, particularly in patients for whom free flap transfers are unviable.

Early debridement (i.e., eschar removal) is regarded as a cornerstone for treating burn wounds. Although surgical debridement is the standard method for complete removal of eschars, it has inefficiencies such as blood loss, heat loss, and poor selectivity, the latter of which means that both viable and necrotic tissue are affected. To make up for the shortcomings, various alternative techniques have been developed. Nexobrid, a mixture of proteolytic enzymes with high bromelain content, has emerged as a viable option in recent years due to its selectivity and efficiency. This product enables dissolving eschar without sacrificing viable or healthy tissue, preserving the potential for spontaneous epithelialization, which accelerates wound healing and leads to better aesthetic outcomes in burn wounds. Herein, we present our experience with proteolytic enzyme debridement using Nexobrid.

Glacial acetic acid is a high-purity acetic acid that is mainly used as a solvent in chemical production and for various purposes in the food and pharmaceutical industries. It is safe enough to be used for chemical peeling when diluted, and has been used in folk remedies for warts, athlete’s foot, and eczema. Indeed, such conditions are the most common reason for exposure to glacial acetic acid. In the present report, we describe the case of a 10-year-old girl who presented with pain and necrosis of the distal phalanx of her left index finger. Two days prior, her fingers had been wrapped overnight with a paste of flour mixed with glacial acetic acid to treat warts. We irrigated the affected area with normal saline, applied a mupirocin ointment, and administered prostaglandin E1. However, the necrosis progressed rapidly. After 10 days, the girl’s fingertip was amputated, and a hypothenar free flap was performed. The case represents a severe chemical burn resulting from the misuse of glacial acetic acid, requiring surgical treatment.

Para isso, foi realizado um estudo sobre a Educação do Campo em tempos de Covid-19, observando os regimentos legislativos, bem como a regulamentação educacional com a propagação do novo Coronavírus. O percurso metodológico se deu a partir de questionários, aplicados entre os dias 16 a 25 de junho de 2021, por meio de uma plataforma de comunicação virtual, o (e-mail) e teve como respondentes os profissionais da Educação do Campo, envolvidos no processo metodológico/pedagógico (06 Professores) e um gestor escolar (01 Diretor). Os resultados da pesquisa constataram carências nos investimentos de políticas públicas educacionais e, principalmente, na Educação do Campo. Além disso, está claro a predominância da precarização do trabalho docente, por meio de cargas horárias excessivas, saúde emocional abalada, ausência do estado em proporcionar condições básicas para que as aulas remotas aconteçam em um momento tão caótico que o sistema determina.
Multi-model evaluation of longitudinal temperature fluctuations and the dominant influencing factors among Michigan streams
Authors: Andrews Ryan , Hayes Daniel , Zorn Troy
Published: October 2021

Stream temperature is an important determinant of fish growth,
migration, and survival, and can thus impact the structure and function
of stream ecosystems. Fluctuations in water temperature can occur
spatially and temporally, occurring naturally or because of
anthropogenic pressures. Many streams in Michigan and elsewhere in North
America receive groundwater inputs that help regulate instream
conditions by stabilizing discharge as well as stream temperature.
However, groundwater withdrawal through high-capacity wells is important
to the agricultural industry and water users for irrigation or municipal
water supplies. Withdrawal can cause reductions in streamflow which
typically results in increased stream temperature. Other atmospheric and
hydrologic variables (i.e. overland discharge) also impact the rate at
which stream temperature changes as it flows downstream. In this study
we deployed paired up- and downstream water pressure and temperature
loggers within 21 stream reaches throughout the state of Michigan to
quantify and model relationships between stream discharge, air
temperature, and longitudinal change in stream temperature (i.e.,
temperature flux). Using multi-model selection criteria, we evaluated
the performance of a hierarchical suite of models that predict
temperature flux rates as a function of potential driving variables. The
multi-model selection criteria identified a best-fitting model that was
able to model the diurnal, seasonal, and annual variations in rates of
longitudinal temperature fluctuations across a majority of sample
streams. Partial regression analysis indicated that proxy variables
representing solar radiation at the stream surface were generally the
most influential predictors of longitudinal changes in stream
temperature, but air temperature and components of streamflow including
groundwater input were significant predictors and important in many
streams.
Cash Flow Volatility and Debt Maturity Structure: Role of Macroeconomic Factors

This study investigated the moderating role of macroeconomic factors in the relationship among CFV and DMS by considering a sample of 380 listed non-financial firms of Pakistan over a period from (1999-2018). Ordered probit regression and executed some standard econometric techniques such as two-way fixed effect, generalized method of moments (GMM), to explain the robustness of main findings. The study findings endeavor that role of macroeconomic factors weakens the CFV relationship with DMS. In addition, carried out a conditional analysis to analyze the effect of cash flow volatility on debt maturity structure at different percentiles (25th, 50th,75th) of macroeconomic variables. The conditional effects results indicate that when inflation, money supply and interest rate vary from low to high level, the inverse effect of cash flow volatility on debt maturity structure is determined. However, when a country experiences higher economic growth the direct effect of cash flow volatility on the debt maturity structure is determined. this research findings suggest some recommendations in the subsequent ways: Firstly, firms when facing variation in the earning level may mitigate their financial distress, cost of bankruptcy by choosing short-term maturity debts. Secondly, the role of macroeconomic factors should be considered by the financial managers in the decision-making process as it effects the firms DMS. Thirdly, non-financial firms, banks, financial institutions may lessen their risk of non-performing loans by limiting their financing when experiencing high CFV.
An Empirical Examination of Relative Income Hypothesis: Evidence from Pakistan
Authors: u Nisa Ishtiaq Mehr , Tauheed Tahira , Ishtiaq Isma
Published: October 2021

The present study empirically investigates the relevance of the various specifications of relative Income hypothesis (RIH) in the case of Pakistan. World Development Indicators’ data is analyzed over the period of 1986 to 2016. This study tests the existence of income, consumption, and habit ratchet effects at the National level. Based on stationarity tests the techniques of Box Jenkin, Two Stage Least Square, Generalized Methods of Moments, and Limited Information Maximum Likelihood Method are utilized to estimate the four versions of relative income hypothesis. Findings of this research validate the significant prevalence of three types of ratchet effects in case of Pakistan. In Duesenberry-Eckstein-Formm (DEF) model, habit ratchet effect is found to be stronger than income ratchet effect. Whereas in modified Davis model Consumption ratchet effect exceeds the habit ratchet effect. It is observed that long run marginal propensities to consume are closer to one which demonstrates smooth consumption behavior over long period in Pakistan. The estimated short run marginal propensities to consume are observed to be less than long run marginal propensities to consume that accords with the existing consumption theory. These findings imply that all ratchet effects put pressure upon consumers to maintain the highest standard of living enjoyed in the past. In this process households do not retain balance between savings and consumption. Based on these findings, it is suggested to consider the impact of societal factor in formulating policies to shape the consumption patterns.
Numerical Study on the Effect of 185/65R14 Tire Rim Width on Dynamic Performance of a B Class Vehicle Model
Authors: Vaseli Shahab , Esfahanian Mohsen
Published: October 2021

In this study, the effect of a passenger car radial tire rim width on its force and moment characteristics (behavior) and subsequently on a vehicle dynamic performance is investigated. The study on the sensitivity of tire behavior to changing its rim width was carried out using the finite element method with the help of Abaqus. For this purpose, the finite element models of a 185/65R14 tire with two rim widths of 5.5″ and 6″ were created and compared in terms of steady-state longitudinal, steady-state lateral, transient longitudinal, and transient lateral behavior, by simulation of stiffness measuring and slip tests. To investigate the effect of rim width on vehicle dynamic performance, several road tests were simulated using a full vehicle dynamic model from CarSim. In each test, at least one of the parameters associated with the discussion of vehicle dynamic performance evaluation including brake distance, understeer gradient, vehicle slip angle, lateral deviation, and roll angle is measured. The vehicle model used is one of the B class instant vehicle models from CarSim, for which this tire size is appropriate. For all subsystems except tires, the same default values were used. For tires, the Pacejka 5.2 tire model is used. Numerical values of the coefficients of this tire model are calculated by fitting the curves of the tire forces and moments obtained from the finite element simulation of required tire tests. The results of the road test simulations have shown that the vehicle with the narrower rim has the better braking ability, but its other behavioral aspects are weaker.
