Published: January 2022

Postoperative cognitive dysfunction (POCD) has been increasingly recognized as a contributor to postoperative complications. A consensus-working group recommended that POCD should be distinguished between delayed cognitive recovery, i.e., evaluations up to 30 days postoperative, and neurocognitive disorder, i.e., assessments performed between 30 days and 12 months after surgery. Additionally, the choice of the anesthetic, either inhalational or total intravenous anesthesia (TIVA) and its effect on the incidence of POCD, has become a focus of research. Our primary objective was to search the literature and conduct a meta-analysis to verify whether the choice of general anesthesia may impact the incidence of POCD in the first 30 days postoperatively. As a secondary objective, a systematic review of the literature was conducted to estimate the effects of the anesthetic on POCD between 30 days and 12 months postoperative. For the primary objective, an initial review of 1,913 articles yielded 12 studies with a total of 3,639 individuals. For the secondary objective, five studies with a total of 751 patients were selected. In the first 30 days postoperative, the odds-ratio for POCD in TIVA group was 0.60 (95% CI = 0.40 - 0.91; p = 0.02), compared to the inhalational group. TIVA was associated with a lower incidence of POCD in the first 30 days postoperatively. Regarding the secondary objective, due to the small number of selected articles and its high heterogeneity, a metanalysis was not conducted. Giving the heterogeneity of criteria for POCD, future prospective studies with more robust designs should be performed to fully address this question.

Published: January 2022

The prediction of children's adult height is a common procedure in childhood endocrinology. Through the prediction of children's adult height, it is possible to find abnormalities in children's growth and development. Many jobs in today's society have certain requirements for height, so the accuracy of children adulthood height prediction is important for children. Current methods for predicting adult height of children have some shortcomings such as inaccurate accuracy. To deal with these problems, this paper analyzes the data collected by the Chinese children and adolescents' physical and growth health projects in primary and secondary schools in Zhejiang Province, and proposes a method for predicting adult height based on back propagation neural network (BPNN) with the body composition of children and adolescents as input. Since the BP algorithm has the risk of falling into local optimization, and we propose LSALO-BP model that incorporates the ant lion optimizer (LSALO) into the BP algorithm as location strategy to avoid local optimization. The improvements achieved by the ant lion algorithm are mainly reflected in: improving the ant's walk mode, and enhancing the global search ability of the LSALO algorithm. The comparison experiment of 10 benchmark functions proves the feasibility and effectiveness of the location strategy. The LSALO-BP model is applied to the prediction of adult height of children and adolescents. The experimental results show that compared with other models, the LSALO-BP prediction model has increased the prediction accuracy by 6.67%~16.08% for boys and 4.67%~6.6% for girls, which can more accurately predict the adult height of children and adolescents.

Tissue-resident macrophages expressing lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1) are found in multiple tissues and organs. We aimed to evaluate the dynamics and biological function of LYVE-1+ macrophages in dental pulp during post-injury tissue remodeling. Immunofluorescence staining of mouse embryos revealed that LYVE-1+ macrophages colonized dental pulp before birth. In mature rat molar dental pulp, LYVE-1+ macrophages were the main subset of macrophages expressing CD163, an M2 marker, and were distributed throughout the tissue. In response to dental pulp injury induced by cavity preparation, LYVE-1+ macrophages quickly disappeared from the affected area of the pulp and gradually repopulated during the wound healing process. RAW264.7 mouse macrophages cultured with a mixture of macrophage colony-stimulating factor, interleukin-4, and dexamethasone increased LYVE-1 expression, whereas lipopolysaccharide-stimulation decreased LYVE-1 expression. Enforced expression of Lyve1 in RAW264.7 cells resulted in increased mRNA expression of matrix metalloproteinase 2 (Mmp2), Mmp9, and vascular endothelial growth factor A (Vegfa). Lyve1-expressing macrophages promoted the migration and tube formation of human umbilical vein endothelial cells. In conclusion, LYVE-1+ tissue-resident M2-like macrophages in dental pulp showed dynamism in response to pulp injury, and possibly play an important role in angiogenesis during wound healing and tissue remodeling.

Published: January 2022

Ischemic stroke is a common and debilitating disease that can cause permanent neurological damage. Gucy1a3, which encodes the α1 subunit of soluble guanylyl cyclase, has been reported to be associated with functional recovery after ischemic stroke. However, the mechanism is still not well understood. In the present study, we investigated the effects of Gucy1a3 on (i) post-stroke recovery; (ii) vascular endothelial growth factor A (VEGFA) and hypoxia inducible factor 1 alpha (HIF-1α) expression; and (iii) angiogenesis after ischemic stroke. A permanent middle cerebral artery occlusion (pMCAO) model was established using wild-type and Gucy1a3 knockout C57BL/6J male mice. Neurological deficits, infarct volume, microvascular density, and VEGFA and HIF-1α expression levels of mice were evaluated. Our results suggest that loss of Gucy1a3 increased the infarct volume and aggravated neurological deficits after pMCAO. In addition, the Gucy1a3 knockout brains exhibited significantly lower microvessel densities and VEGFA and HIF-1α expression levels than the wild-type brains at 96 hours post-pMCAO. The study shows that the expression of GUCY1A3 after ischemic stroke may play a substantial role in neurological function recovery and is related to angiogenesis in the peri-infarct region. The beneficial effects of GUCY1A3 might be mediated through the HIF-1α/VEGFA signaling pathway.

Published: January 2022

Dynamic changes in soil organic matter content affects the sustainable supply of soil water and fertilizer and impacts the stability of soil ecological function. Understanding the spatial distribution characteristics of soil organic matter will help deepen our understanding of the differences in soil organic matter content, soil formation law; such understanding would be useful for rational land use planning. Taking terrain data, meteorological data, and remote sensing data as auxiliary variables and the ordinary Kriging (OK) method as a control, this study compares the spatial prediction accuracies and mapping effects of various models (MLR, RK, GWR, GWRK, MGWR, and MGWRK) on soil organic matter. Our results show that the spatial distribution trend of soil organic matter predicted by each model is similar, but the prediction of composite models can reflect more mapping details than that of unitary models. The OK method can provide better support for spatial prediction when the sampling points are dense; however, the local models are superior in dealing with spatial non-stationarity. Notably, the MGWR model is superior to the GWR model, but the MGWRK model is inferior to the GWRK model. As a new method, the prediction accuracy of MGWRK reached 47.72% for the OK and RK methods and 40.08% for the GWRK method. The GWRK method achieved a better prediction accuracy. The influence mechanism of soil organic matter is complex, but the MGWR model more clearly reveals the complex nonlinear relationship between soil organic matter content and factors influencing it. This research can provide reference methods and mapping technical support to improve the spatial prediction accuracy of soil organic matter.

Published: January 2022

This study aimed to measure the levels of airborne radon (Rn) and bioaerosols—culturable airborne bacteria (CAB) and culturable airborne fungi (CAF)—in South Korea’s residential environments, considering living conditions such as the number of ventilations, number of windows, floors, temperature, and relative humidity. These levels were evaluated for 32 houses of residents from the socially vulnerable class. Rn gas and bioaerosols were sampled twice: in fall and summer. A self-report survey gathered residents’ information on their general characteristics (daily residence time, heating and cooking type, cleaning and washing cycle, etc.) and health condition scores (0–100 points) on the day of sampling. The range of Rn levels was 0.43–7.439 pCi/L with a median of 0.70 pCi/L. The CAB levels were 239–488 colony-forming unit (CFU)/m3 with a median of 309 CFU/m3, and CAF levels were 174–366 CFU/m3 with a median of 233 CFU/m3. Thus, this study found that semi-basement residential indoor environments negatively affected Rn and bioaerosol levels, and living in such residences resulted in high health condition scores.

Published: January 2022

Objectives: The knowledge, attitude and practice of skin-whitening products among female undergraduates in the medical campus, University of Khartoum.Methods: A cross-sectional study was conducted at the medical campus of University of Khartoum. All consenting female undergraduates were included in the study population. 417 women were chosen through proportional stratified random sampling, and were asked to complete a questionnaire.365 completed the questionnaire with a response rate of 87%. Result: 365 women completed the questionnaire, of whom 52% had average knowledge, 32% had poor knowledge and 16% had excellent knowledge,.32% had a positive attitude, and 38% reported using skin-whitening products.Knowledge, attitude and practice were associated with several factors.Conclusion : Although The overall knowledge about skin-whitening products is average. The knowledge about skin-whitening agents is rather poor. The majority of Sudanese University students have a negative attitude towards skin-whitening, but still the use of skin-whiteners is common amongst them .. Women who feel pressured by society to whiten their skin, are more likely to use skin-whiteners, as well as those who have a family history of skin-whitening. Media and social media play an important role in this matter, being the most important source of information and the most common factor pressuring women to lighten their skin as well. We recommend media and social to be used to promote the acceptance of dark skin and raise awareness about the safe practice of skin whitening. We also recommend that the Ministry of Health and Standards and Metrology Authority mandate the labeling of all products sold in Sudan detailing ingredients and concentrations of ingredients.

Published: January 2022

Purpose: Patient satisfaction with treatment is associated with adherence to therapy. This study aimed to investigate the treatment satisfaction level of patients with chronic obstructive pulmonary disease (COPD) and to explore the underlying factors associated with patient satisfaction. Methods: A cross-sectional study was conducted in ambulatory patients at the Second Xiangya Hospital, Changsha, Hunan, between August 1, 2020, and May 31, 2021. The Treatment Satisfaction Questionnaire for Medication version II (TSQM v. II) was used to assess the treatment satisfaction of patients. Multivariable regression analysis was used to determine the factors associated with treatment satisfaction. Results: 392 ambulatory patients with COPD first participated in the study, and 354 patients with are finally available. Median (IQR) score in effectiveness was 66.67(50.00, 66.67), in side effects was 100(100,100), in convenience was 66.67(66.67, 66.67), in global satisfaction was 66.67(50.00, 66.67).Compared with the unsatisfied group, the patients who were satisfied with the treatment had fewer acute exacerbations in the past year (0 vs 1,p＜0.001), lower CAT scores(10 vs 13, p＜0.001), lower CCQ scores(1.95 vs 2.24, p＜0.001), lower GOLD group classification(p＜0.001) and lower BODE index[3.00(1.00, 4.25) vs 3.00(2.00, 5.00), p=0.006].

Published: January 2022

Facing the untrusted threats of network elements and PKI/CA faced by SR-BE/TE(Segment Routing-BE/TE) data plane in the zero-trust network environment, firstly, this paper refines it into eight specific security issues. Secondly, an SR-BE/TE data plane security model ZbSR(ZTA-based SR) based on zero-trust architecture is proposed, which reconstructs the original SR control plane into a "trust-agent" two-layer plane based on 4 components of the controller, agent, cryptographic center and information base. On one hand, we distinguish between the two segment list generation modes and proposes corresponding data exchange security algorithms, by introducing north-south security verification based on identity authentication, trust evaluation, and key agreement before the terminal device establishes an east-west access connection, so reliable data exchange between terminal devices can be realized. On the other hand, for the network audit lacking SR-BE/TE, a network audit security algorithm based on solid authentication is proposed. By auditing the fields, behaviors, loops, labels, paths, and SIDs of messages, threats such as stream path tampering, SID tampering, DoS attacks, and loop attacks can be effectively detected. Finally, through the simulation test, the proposed model can provide security protection for the SR data plane with a 19.3% average incremental delay overhead for various threat scenarios.
The Impact of Direct Challenges to Student Endorsement of Teleological Reasoning on Understanding and Acceptance of Natural Selection
Authors: Wingert Jason , Bassett Gennie , Terry Caitlin , Lee Jimin
Published: January 2022

Background: Teleological reasoning is a cognitive bias purported to disrupt student ability to understand natural selection. Few studies have described pedagogical efforts to decrease student endorsement of teleological reasoning and measure the effects of this attenuation on the understanding and acceptance of evolution. This study examined the influence of explicit instructional activities directly challenging student endorsement of teleological explanations for evolutionary adaptations on their learning of natural selection over a semester-long undergraduate course in evolutionary medicine. In a convergent mixed-methods design this study combined pre- and post-semester survey data (N = 83) on understanding natural selection, student endorsement of teleological reasoning, and acceptance of evolution, with thematic analysis of student reflective writing on their understanding and acceptance of natural selection and teleological reasoning.Results: Student endorsement of teleological reasoning decreased and understanding and acceptance of natural selection increased during a course on human evolution with teleological intervention (p£0.0001), compared to a control course. Endorsement of teleological reasoning was predictive of understanding of natural selection prior to the semester. Thematic analysis revealed that students were largely unaware of the concept of teleological reasoning prior to the course, but perceived attenuation of their own teleological reasoning by the end of the semester. Conclusions: Students are unaware of their high levels of endorsement of teleological reasoning upon entrance into the undergraduate human evolution course, which is consequential because teleological reasoning is a predicter of natural selection understanding. We developed class activities to directly challenge student endorsement of unwarranted design teleological reasoning. As a result, students had decreased unwarranted teleological reasoning and increased acceptance and understanding of natural selection over the course of the semester. The data presented show that students are receptive to explicit instructional challenges to their teleological reasoning and that attenuation of this bias is associated with gains in natural selection understanding and acceptance.

Published: January 2022

Background

Canine Leishmania infantum infection is a major vector-borne zoonosis. Most cases of canine leishmanias are caused by Leishmania infantum, but other species can also be found. In the Old and New Worlds, leishmaniasis is spread by the bite of phlebotomine female sandflies of the genera Phlebotomus and Lutzomyia respectively. The objectives of the study were to estimate the seroprevalence and associated risk factors in Weliso, Ambo, and Ejaji towns of South-West and West Shewa Zones, Oromia, Ethiopia.
Methods

A cross-sectional study was conducted from October 2019 to September 2020. The study population consists of dogs found in the study towns. The study subjects include 368 dogs selected by using a simple random sampling method. A blood sample (5 ml) was collected to test for the presence of rK39 antigen inducing specific antibodies using an Indirect ELISA kit. All the data were analyzed using the STATA version 14 software program. Pearson’s Chi-square and logistic regression tests were used to evaluate the association between the seropositivity of canine Leishmania infantums and hypothesized risk factors.
Results

An overall canine Leishmania infantum seroprevalence of 84.24% (95% confidence interval [CI]: 80 - 88%) was obtained. In Weliso, Ambo, and Ejaji towns canine Leishmania infantum seroprevalence of 79.82% (95% CI: 71- 87%), 76.11% (95% CI: 67- 84%), and 93.84% (95% CI:89 – 97%) were found respectively. Univariable logistic regression analysis showed that town (P=0.001), season (P=0.001), mixed living environment (P=0.003), and Kebele (P<0.05) were significantly associated with Leishmania infantum seropositivity. However, the multivariable analysis indicated that wet season (P = 0.001) and a mixed living environment (P = 0.025) were independent predictors of canine Leishmania infantum seropositivity.
Conclusion

The seroprevalence of canine Leishmania infantum in dogs was very high. Wet season and mixed living environment are predictors of seropositivity. The high percentage of seropositive dogs indicates the potential role of dogs to maintain the infection and the possible spread of L. infantum infection to humans. Therefore, improvement of the living environment and health care facilities of domesticated dogs, community awareness and health education, and further epidemiological studies are suggested.

Purpose: To evaluate maternal and perinatal outcomes in high-risk patients who had negative OCTs and to investigate the effects of methods of induction on the development of fetal distress. Methods: The hospital records of patients were reviewed retrospectively. Clinical data were obtained from medical records. Results: OCT was performed in 551 patients and was negative in 447 patients. Among patients with a negative OCT, labor induction was preferred in 427 (95.5%) patients. When fetal distress development was assessed according to the induction method used following a negative OCT, and fetal distress developed in 9.1% of 427 patients who underwent labor induction. Conclusion: When outcomes were considered in pregnant women with a negative OCT, it was observed that there were no fetal deaths and a limited number of newborns with low Apgar scores. Further randomized studies are needed to draw definitive conclusions.

Authors: Swarup Shivam , Kushwaha Gyaneshwar Singh
Published: January 2022

The fluctuations in the Onion prices have led to political and economic ramifications in countries such as India. In this study, we intend to estimate and then forecast the price volatility of Onion sales prices in major Indian wholesale markets. Initially, we take daily price data from major vegetable wholesale markets across India and simulate them to compute corresponding daily conditional volatilities using the traditional GARCH method. We then forecast the volatilities for the upcoming 10,15 and 21 days using the same traditional GARCH method and compare its forecasting accuracy with recent AI-led models. According to our comparisons, the deep learning-based LSTM model with various configurations provides superior results when compared to other traditional models with the highest accuracy in more than 70% of the cases. We expect that the given study could help the policymakers in managing sufficient buffer stock levels and the food supply chain stakeholders in hedging against the overall market risks due to the fluctuations in prices.

Published: January 2022

COVID-19 vaccines are considered one of the primary strategies for countering the pandemic. While mRNA based and viral vector-based vaccines have been predominantly used, inactivated SARS-CoV-2 vaccines are being manufactured in countries such as China and India. Post approval, rare but serious adverse events such as myocarditis and stroke have been observed with mRNA based and viral vectored COVID-19 vaccines. Inactivated vaccines in general have shown better tolerability in clinical trials. Here we report the first case of new-onset seropositive rheumatoid arthritis (RA) with rheumatoid nodules and refractory reactive eosinophilia within two weeks of receiving an inactivated COVID-19 vaccine (COVAXIN).
TinyLFU-Based Semi-Stream Cache Join for Near-Real-Time Data Warehousing

Published: January 2022

Semi-stream join is an emerging research problem in the domain of near-real-time data warehousing. A semi-stream join is basically a join between a fast stream (S) and a slow disk-based relation (R). In the modern era of technology, huge amounts of data are being generated swiftly on a daily basis which needs to be instantly analyzed for making successful business decisions. Keeping this in mind, a famous algorithm called CACHEJOIN (Cache Join) was proposed. The limitation of the CACHEJOIN algorithm is that it does not deal with the frequently changing trends in a stream data efficiently. To overcome this limitation, in this paper we propose a TinyLFU-CACHEJOIN algorithm, a modified version of the original CACHEJOIN algorithm, which is designed to enhance the performance of a CACHEJOIN algorithm. TinyLFU-CACHEJOIN employs an intelligent strategy which keeps only those records of $R$ in the cache that have a high hit rate in S. This mechanism of TinyLFU-CACHEJOIN allows it to deal with the sudden and abrupt trend changes in S. We developed a cost model for our TinyLFU-CACHEJOIN algorithm and proved it empirically. We also assessed the performance of our proposed TinyLFU-CACHEJOIN algorithm with the existing CACHEJOIN algorithm on a skewed synthetic dataset. The experiments proved that TinyLFU-CACHEJOIN algorithm significantly outperforms the CACHEJOIN algorithm.
Subordinasi dan Sudut Pandang Perempuan Suku Malind Marga Mahuze dalam Film the Mahuzes (2015): a Feminist Standpoint Theory
Authors: Arfiani Dini
Published: January 2022

Abstract: Documentary films are one of the most suitable media to be used as a reference in seeing reality. Like the reality of subordination and women's point of view in The Mahuzes. In general, this film tells the story of the conflict that occurred between the Malind clan Mahuze in Merauke and corporations that entered their territory through the Merauke Integrated Food and Energy Estate (MIFEE) program, besides that there were horizontal conflicts between tribal members. This study aims to analyze the form of subordination and women's point of view seeing the problems of indigenous peoples dealing with corporations which are shown by the documentary film The Mahuzes in the perspective of Feminist Standpoint Theory. This study uses a qualitative approach and a critical paradigm by collecting data from various relevant sources. Events involving or relating to women were analyzed using three basic concepts of Feminist Standpoint Theory, namely standpoint, situated knowledge, and sexual division of labour. The results of the study indicate that women in The Mahuzes are a marginalized group, forced to take responsibility for the domestic space, and are limited to take part in the public sphere. Even so, they have a broad and comprehensive perspective in viewing horizontal conflicts between clan members and vertically between clans and corporations.

Abstract: Social distancing are a form of policy that made by the government in order to prevent the spread of the COVID-19 virus. This method, that was made by Indonesian government has implications for the method of working in the pandemic era, namely working from home. The application of social distancing then causes an increase in household activities that increase women's responsibilities in parenting and household work. Through the concept of symbolic violence, this article tries to explain the impact of social distancing restrictions on working women. This article finds that symbolic violence occurs through habitus that shapes women's mindsets so that they feel that caregiving and household work are women's responsibilities. This article also finds various gender inequalities that are increasingly visible with the social distancing restrictions that implemented by Indonesian governement.

Automatic differentiation applied to excitations with projected entangled pair states
Authors: Ponsioen Boris , Assaad Fakher , Corboz Philippe
Published: January 2022

The excitation ansatz for tensor networks is a powerful tool for simulating the low-lying quasiparticle excitations above ground states of strongly correlated quantum many-body systems. Recently, the two-dimensional tensor network class of infinite projected entangled-pair states gained new ground state optimization methods based on automatic differentiation, which are at the same time highly accurate and simple to implement. Naturally, the question arises whether these new ideas can also be used to optimize the excitation ansatz, which has recently been implemented in two dimensions as well. In this paper, we describe a straightforward way to reimplement the framework for excitations using automatic differentiation, and demonstrate its performance for the Hubbard model at half filling.
Bose polaron in a quantum fluid of light
Authors: Vashisht Amit , Richard Maxime , Minguzzi Anna
Published: January 2022

We study the Bose polaron problem in a nonequilibrium setting, by considering an impurity embedded in a quantum fluid of light realized by exciton-polaritons in a microcavity, subject to a coherent drive and dissipation on account of pump and cavity losses. We obtain the polaron effective mass, the drag force acting on the impurity, and determine polaron trajectories at a semiclassical level. We find different dynamical regimes, originating from the unique features of the excitation spectrum of driven-dissipative polariton fluids, in particular a non-trivial regime of acceleration against the flow. Our work promotes the study of impurity dynamics as an alternative testbed for probing superfluidity in quantum fluids of light.

El populismo como amenaza a la Democracia: un análisis de la Carta Democrática Interamericana
Authors: López Alfonsín Marcelo Alberto , Bucetto María Sol
Published: January 2022

La promoción de la democracia ha sido una de las principales misiones del sistema interamericano de derechos humanos. En este sentido, la adopción de la Carta Democrática Interamericana constituye un hito a razón de que representa la síntesis de una serie de mecanismos jurídicos y diplo¬máticos que los Estados miembros fueron desarrollando y proporciona una herramienta valiosa para la defensa colectiva del sistema democrático. Sin embargo, en la actualidad uno de los desafíos de los sistemas regionales es el populismo autoritario que socava la esencia institucional y la calidad de la democracia. Es posible observar que, hasta el momento, las respuestas de la OEA ante situaciones de amenaza del orden constitucional han sido firmes, pero han fallado en reaccionar cuando los presidentes han utilizado los mecanismos democráticos formales para concentrar el poder.

Published: January 2022

A Lei Complementar n° 128, de 19 de dezembro de 2008, que criou o Microempreendedor Individual (MEI), possibilitou uma forma fácil, de baixo custo e incentivadora para a legalização de empreendimentos. A quantidade de MEIs vem crescendo, porém ainda há poucos estudos para conhecer melhor seu perfil. Aproveitando esta lacuna, este estudo apresenta o perfil sociodemográfico do MEI ativo de Severiano de Almeida (RS), além de identificar os ramos de atuação destes MEIs, verificar quais os benefícios que os empreendedores desejavam com a formalização e a forma de gerenciamento dos seus negócios. O estudo empregou as abordagens qualitativa e quantitativa. Para coleta dos dados foram utilizados questionário e documentos da Prefeitura Municipal de Severiano de Almeida, do Portal do Empreendedor e do SEBRAE. A amostra foi de quarenta e sete MEIs. Quanto ao perfil, verificou-se que não há disparidade entre os gêneros, a faixa etária predominante é de 21 e 40 anos e estes têm ensino médio completo. O ramo de atuação dos MEI’s severianenses que se destaca é a construção civil. Em relação aos principais motivos para formalização como MEI, o mais citado foi os benefícios disponibilizados pelo INSS. Os resultados trazem preocupação no que se refere a continuidade do negócio, já que vários pontos negativos foram levantados no decorrer da análise no que se refere ao planejamento e ao gerenciamento dos negócios. Conclui-se que os MEIs severianenses devem mudar as suas percepções quanto a busca por qualificação e atualização.

Published: January 2022

Substance Use Disorder (SUD) is a social phenomenon that has plagued communities, including adolescents. Coping strategy and drug hazard knowledge are seen as important factors in curbing drug use amongst young people. This study aims to identify the indirect influence of coping strategy through drug hazard knowledge as a mediator in substance use disorders. The research employed a quantitative approach with a cross-sectional design, with a sample of 381 adolescents, 313 males and 68 females, selected using a simple random sampling technique. The research instruments comprised the Drugs Abuse Screening Test-28, a coping scale, and drug hazard knowledge scale. AMOS 20.0 for Structural Equation Modelling (SEM) was used for the analysis. The results show no significant indirect influence of coping strategy through drug hazard knowledge as a mediator in substance use disorder among adolescents. This indicates that drug hazard knowledge has no significant influence on substance use disorders.
Are you Awake? Preventing Zoom-fatigue in Online Anatomy & Physiology Courses
Authors: Weiss Valerie , Silevis Rob , Reuter Peter
Published: January 2022

Anatomy and physiology lectures, traditionally held face-to-face at Florida Gulf Coast University, moved overnight to an online environment during the Covid-19 pandemic. Reflecting back on our teaching experience, a few goals to successful Zoom-based teaching emerged: make meaningful connections with the students, stay connected with students by using questions during lectures, and enjoy this new connection throughout the semester and beyond. This article discusses one strategy employed to stay connected to students during virtual, Zoom-based teaching: the use of “Are you awake?” questions. The questions were written to guide students in their review of material just learned. We felt that this method resulted in scaffolding the students’ experience, preventing unnecessary lecturing, and reducing Zoom-fatigue. By emphasizing a process of regularly “checking in” with the student, a further relationship was established between the course faculty and students as well as among the students. Anecdotal evidence of this question technique is shared, with student feedback being positive. Based on our experience, emotional presence in the online environment correlates to student success.
"But what are you doing to help them learn?" Reflections on a Career Teaching Human anatomy and Physiology
Authors: Seithers Laura , LePage Peggy , Jensen Murray
Published: January 2022

This narrative study tells the teaching and learning story of the recently retired Dr. Peggy LePage, a longtime member of the Human Anatomy and Physiology Society with a career as a community college anatomy and biology professor spanning nearly three decades. Drawn from a lengthy narrative interview, this paper describes Dr. LePage’s background as a nontraditional student and explores her resilience as a woman in science, technology, engineering, and mathematics (STEM). When Dr. LePage neared a breaking point early in her career, an encounter with a well-known advocate for active learning in science classrooms transformed her pedagogy. She also became involved with HAPS and never looked back. Narrative passages from her interview emphasize Dr. LePage’s persistence in STEM, her shift toward a teacher as learner mentality, and the benefits of learning communities for anatomy and physiology instructors.
New Uses of Melatonin as a Drug; A Review
Authors: Pohanka Miroslav
Published: January 2022

Melatonin is a simple compound called N-acetyl-5-methoxy tryptamine and is
known as a hormone controlling the circadian rhythm. Melatonin is produced by the human
body naturally. The production of melatonin increases in the evening, causing a
state of sleep at night and wakefulness during the day. Melatonin interacts with melatonin
receptors MT1 and MT2, but it was revealed that melatonin is a strong antioxidant
and it also has a role in the regulation of the cell cycle. Melatonin is now used as a
medicine to treat some types of sleep disorders. Moreover, recent research suggests that
it can also be utilized for other purposes, such as prevention from chemical exposure and
treatment of various diseases, including cancer, neurodegenerative disorders, etc. This review
summarizes the basic facts and direction of the current research on melatonin. The
existing literature was scrutinized for this review.
In Silico Trial Approach for Biomedical Products: A Regulatory Perspective
Authors: Jose Jobin , S. Shifali , Mathew Bijo , Parambi Della Grace Thomas
Published: January 2022

The modern pharmaceutical industry is transitioning from traditional methods to advanced
technologies like artificial intelligence. In the current scenario, continuous efforts are being
made to incorporate computational modeling and simulation in drug discovery, development,
design, and optimization. With the advancement in technology and modernization, many pharmaceutical
companies are approaching in silico trials to develop safe and efficacious medicinal products.
To obtain marketing authorization for a medicinal product from the concerned National Regulatory
Authority, manufacturers must provide evidence for the safety, efficacy, and quality of medical
products in the form of in vitro or in vivo methods. However, more recently, this evidence was
provided to regulatory agencies in the form of modeling and simulation, i.e., in silico evidence.
Such evidence (computational or experimental) will only be accepted by the regulatory authorities
if it considered as qualified by them, and this will require the assessment of the overall credibility
of the method. One must consider the scrutiny provided by the regulatory authority to develop or
use the new in silico evidence. The United States Food and Drug Administration and European
Medicines Agency are the two regulatory agencies in the world that accept and encourage the use
of modeling and simulation within the regulatory process. More efforts must be made by other regulatory
agencies worldwide to incorporate such new evidence, i.e., modeling and simulation (in silico)
within the regulatory process. This review article focuses on the approaches of in silico trials,
the verification, validation, and uncertainty quantification involved in the regulatory evaluation of
biomedical products that utilize predictive models.
Numerical Examination on Impact of Hall Current on Peristaltic Flow of Eyring-Powell Fluid under Ohmic-Thermal Effect with Slip Conditions
Authors: Abdeljawad Thabet , Sohail Muhammad , Yasin Maria , Hina Sadia , Naz Rahila
Published: January 2022

Aims::

This article is intended to investigate and determine the combined impact of
Slip and Hall current on Peristaltic transmission of Magneto-hydrodynamic (MHD) Eyring-
Powell fluid.

Background:

The hall term arises, taking strong force-field under consideration. Velocity, thermal,
and concentration slip conditions are applied. The energy equation is modeled by considering
the Joule-thermal effect. To observe the non-Newtonian behavior of the fluid, the constitutive
equations of Eyring-Powell fluid are encountered.

Objective:

Flow is studied in a wave frame of reference traveling with the wave's velocity. The
mathematical modeling is done by utilizing adequate assumptions of long wavelength and low
Reynolds number.

Method:

The closed-form solution for momentum, temperature, and concentration distribution
is computed analytically using the regular perturbation technique for the small fluid
ter(A).

Results:

Graphical results are presented and discussed in detail to analyze the behavior of sundry
parameters on flow quantities (i.e., velocity, temperature, and concentration profile). It is noticed
that Powell-Eyring fluid parameters (A,B) have a significant role in the outcomes.

Conclusion:

The fluid parameter A magnifies the velocity profile, whereas the other fluid parameter
B shows the opposite behavior.

Published: January 2022

Background:

Erdheim-chester disease (ECD) is a rare non-Langerhans histiocytosis of unknown etiology, which typically presents with bilateral symmetric osteosclerosis and multi-organ involvement. Lesions may be intraosseous or extraosseous and involve the heart, pulmonary system, CNS, and skin in order of decreasing likelihood.

Objective:

The objective of this study is to discuss a case of erdheim-chester disease and conduct a review of the literature.

Case:

We describe a rare case of erdheim-chester in an asymptomatic 37-year-old male who was diagnosed after suffering a right ulnar injury. Subsequent evaluation revealed a solitary radiolucent ulnar lesion without multi-system involvement.

Results & Conclusion:

The case is unique in its solitary distribution, lytic radiographic appearance, and asymptomatic presentation preceding pathologic fracture. This presentation may simulate multiple other bone lesions.
