Ultrasound-Tailored Treatment of Subacromial Shoulder Pain
Authors: Mishra Shailesh Kumar , Kaur Depinder , Dhanda Manjeet Singh
Published: November 2022

Background and Objectives:

Subacromial shoulder pain is the most common cause of shoulder pain consultation in musculoskeletal practice. Partial supraspinatus tendon tears have frequently been treated using a subacromial corticosteroid injection or surgery. The clinical use of a platelet-rich plasma (PRP) injection is an alternative treatment method for the condition, despite the paucity of evidence of its efficacy. The objective of the study was to assess the clinical effectiveness of autologous PRP in comparison to steroid injection in terms of pain relief and functional restoration in subacromial shoulder pathology.

Methodology:

All the patients above 18 years of either sex presenting with complaints of shoulder pain and painful abduction and elevation of arm for more than 6 weeks and not received any steroid injection in the previous 6 months were included in the study. In intra-articular PRP (IA-PRP), i.e., test group, 20 patients received 3 ml of single IA PRP injection, and in the steroid group (control group), 20 patients received 1 ml of intra-articular corticosteroid (IA CS) into glenohumeral joint under ultrasound (US) guidance. All patients were prospectively followed for 6 months.

Results:

There were no differences in visual analog scale (VAS) and disability scores between the PRP and corticosteroid groups at 1-month follow-up. However, the PRP group had better scores than the corticosteroid group on both the VAS and disability scores at 3- and 6-month follow-up. The VAS and disability scores did not change significantly at 6-month follow-up in the corticosteroid group; however, the PRP group showed continued improvement in both VAS and disability scores between 1- and 6-month follow-up. The PRP group had better scores than the corticosteroid group on shoulder range of motion after postintervention follow-up after 1 month. There were no complications in either group.

Conclusion:

Both subacromial PRP and corticosteroid injections had a positive clinical response in the treatment of shoulder pain. In view of the reached results, it may be assumed that steroid injections may provide symptomatic relief but not promote healing which makes PRP injection a good alternative as it is simple, easy to use, easily available, prepared from patient's own blood, and cost-effective. US-guided injections may increase the efficacy of accurately targeted injections.

Published: November 2022

Background and Objectives:

Saline adenine glucose mannitol (SAGM) with citrate phosphate dextrose (CPD) or CPD adenine (CPDA) are two common red cell preservatives used in our country. This study analyzed and compared serial biochemical changes on different days of storage in irradiated packed red blood cells stored in CPDA and SAGM solutions. The aim of this study was to see if these changes are influenced by or different, if any, in these two storage solutions.

Patients and Methods:

Ninety units of RBCs were randomly chosen, with 45 units each collected in CPDA and SAGM, respectively. Nine units each were irradiated by gamma irradiator using cobalt 60 (BI 2000) on days 1, 7, 14, and 21 of their storage, respectively. Nine units were not irradiated and used as controls. All the units were weekly assessed for their plasma levels of potassium, sodium, glucose, lactate dehydrogenase (LDH), and lactate by Clinical Chemistry Auto-analyzer, Beckman Coulter AU680. The values were documented and analyzed by SPSS.

Results:

Baseline values on day 1 for potassium, lactate, and LDH were similar between SAGM- and CPDA-stored blood bags. Glucose and sodium levels were slightly higher in SAGM bags compared to CPDA. Postirradiation, the changes (increase in K+, Lactate, LDH and decrease in Na+, glucose) were higher in CPDA bags than SAGM bags, and the difference in this trend was not significantly different from that seen in nonirradiated blood bags stored in these two preservative solutions.

Conclusion:

Storage lesions (biochemical parameters) after irradiation were severe, but paralleled that observed in nonirradiated bags. The storage solution, either SAGM or CPDA, made no difference to these changes.

Authors: Hossain Fatema , Khatun Ayesha , Islam Md. Ashadul , Miah Sonia Shormin , Saha Subarna , Tanni Nusrat Noor
Published: November 2022

Background and Objectives:

Children with thalassemia are much more vulnerable to being infected by hepatitis B virus (HBV) through transfusion of blood and blood products. Although active immunization against HBV in early infancy is being conducted in Bangladesh by the inclusion of the hepatitis B vaccine (HepB) in the expanded programme on immunization schedule, these children might have altered immune response against HepB due to inevitable iron overload resulting from the disease thalassemia itself as well as repeated transfusion therapy and also from exposure to different allogeneic antigens. The present study was designed to determine the immune response of HepB among transfusion-dependent thalassemic children.

Patients and Methods:

This cross-sectional study was conducted at a university hospital in Bangladesh. A total of 45 transfusion-dependent thalassemic children were included according to inclusion and exclusion criteria. Data collection was conducted through a structured questionnaire after taking written informed consent from each participant's guardian. Each patient underwent a detailed history taking and antibody to hepatitis B surface antigen (anti-HBs) titer was estimated to see the immune response against HepB.

Results:

Collected data were analyzed using SPSS version 23. The mean age of the studied children was 9.03 ± 3.78 standard deviation with slight female predominance (51.1% female and 48.9% male). According to the level of anti-HBs titer, the majority (44.4%) had moderate protection, whereas others had no (28.9%) or strong (26.7%) protection. No significant association between the total number of transfusions (approximate), different age groups, and postvaccination interval with anti-HBs titer was observed (P > 0.05).

Conclusion:

The present study observed an overall poor immune response against HepB as approximately only one-fourth of the study participants got strong protection against HBV. Assessment of anti-HBs titer followed by booster dose or revaccination if necessary is needed to be considered in transfusion-dependent thalassemic children vaccinated in early infancy.

Authors: Ong Wan Xi , Chong Siew Koon , Zakaria Norzila , Bakar Raishan Shafini
Published: November 2022

Background:

The Malaysian education system is moving from predominantly examination oriented to a more holistic continuous approach. Keeping up with paradigm change may cause psychological distress to teachers. Teachers’ sense of efficacy (TSE) is beneficial in coping with psychological distress in keeping up with such changes. This article discusses the prevalence of psychological distress among primary school teachers, its correlation with the level of sense of efficacy and associated sociodemographic factors.

Methods:

A cross-sectional study was conducted among 294 primary school teachers randomly chosen from ten schools in Kinta Utara District, Perak, Malaysia. Three questionnaires were used, namely sociodemographic profile, TSE Scale (TSES), and Depression Anxiety Stress Scale-21. Statistical analysis was performed using SPSS Statistical software version 26.

Results:

The mean scores of TSES were: TSE 7.1 (standard deviation [SD] 0.9), efficacy in classroom management (CME) 7.3 (SD 1.0), efficacy in instructional strategies (ISEs) 7.1 (SD 0.9) and efficacy in student engagement 7.0 (SD 1.0). This study showed the prevalence of depression, anxiety, and stress among teachers at 22.1%, 44.6%, and 17.0%, respectively. Multiple logistic regression analysis indicated that depression was negatively correlated with ISEs, while stress and anxiety were negatively correlated with CME.

Conclusion:

This study revealed that teachers with lower self-efficacy are more likely to experience psychological distress. It is important to improve teacher efficacy, especially in classroom management and instructional strategies, besides providing intervention for any mental health issues.

Published: November 2022

Background:

Intestinal metaplasia (IM) of the gastric cardia is an important premalignant lesion. However, there is limited information concerning its epidemiological and molecular features. Herein, we aimed to provide an overview of the epidemiological data for gastric cardiac IM and evaluate the role of EYA transcriptional coactivator and phosphatase 4 (EYA4) as an epigenetic biomarker for gastric cardiac IM.

Methods:

The study was conducted in the context of the gastric cardiac precancerous lesion program in southern China, which included 718 non-cancer participants, who undertook endoscopic biopsy and pathological examination in three endoscopy centers, between November 2018 and November 2021. Pyrosequencing and immunohistochemistry were performed to examine the DNA methylation status and protein expression level of EYA4.

Results:

Gastric cardiac IM presented in 14.1% (101/718) of participants and was more common among older (>50 years; 22.0% [95% CI: 17.8–26.8]) than younger participants (≤50 years; 6.7% [95% CI: 4.5–9.9]; P < 0.001). IM was more common in male participants (16.9% [95% CI: 13.2–21.3] vs. 11.3% [95% CI: 8.3–15.1]; P = 0.04). Pyrosequencing revealed that IM tissues exhibited significantly higher DNA methylation levels in EYA4 gene than normal tissues (P = 0.016). Further, the protein expression level of EYA4 was reduced in IM and absent in intraepithelial neoplasia tissues compared to normal tissues (P < 0.001).

Conclusions:

Detection rates of gastric cardiac IM increase with age and are higher in men. Our findings highlight the important role of promoter hypermethylation and downregulation of EYA4 in gastric cardiac IM development.
A general result on the approximation of local conservation laws by nonlocal conservation laws: The singular limit problem for exponential kernels
Authors: Coclite Giuseppe Maria , Coron Jean-Michel , De Nitti Nicola , Keimer Alexander , Pflug Lukas
Published: November 2022

We deal with the problem of approximating a scalar conservation law by a conservation
law with nonlocal flux. As convolution kernel in the nonlocal flux, we consider an exponential-type
approximation of the Dirac distribution. We then obtain a total variation bound on the nonlocal
term and can prove that the (unique) weak solution of the nonlocal problem converges strongly in

C({L_{loc}^{1}})

to the entropy solution of the local conservation law. We conclude with several numerical illustrations which underline the main results and, in particular, the difference between the solution and the nonlocal term.
On the self-similar behavior of coagulation systems with injection
Authors: Ferreira Marina A. , Franco Eugenia , Velázquez Juan J. L.
Published: November 2022

In this paper we prove the existence of a family of self-similar solutions for a class of coagulation equations with a constant flux of particles from the origin. These solutions are expected to describe the longtime asymptotics of Smoluchowski’s coagulation equations with a time-independent source of clusters concentrated in small sizes.
The self-similar profiles are shown to be smooth, provided the coagulation kernel is also smooth. Moreover, the self-similar profiles are estimated from above and from below by

x^{-(\gamma+3)/2}

as

x \to 0

, where

\gamma <1

is the homogeneity of the kernel, and are proven to decay at least exponentially as

Authors: Yang Jin , Cheng Shi Qi , Shi Rui , Ying Qin Shang , Huang Li , Lin Wang Yi
Published: November 2022

ABSTRACT. WO3 nanosheets (NSs) were prepared and characterized by X-ray photoelectron spectrometer (XPS), X-ray diffractometer (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). The obtained WO3 NSs exhibited peroxidase-like catalytic activity, which can catalyze H2O2 to oxidize       3,3 ',5,5 '-tetramethylbenzidine (TMB) to generate oxidized TMB (oxTMB) with an absorption peak centered at 652 nm. Based on this, a facile method for the spectrophotometric determination of H2O2 was established. Under the selected conditions, the increase in absorbance of oxTMB enabled the detection of H2O2 ranging from 2.0 to 180 μM. Considering the fact that H2O2 is one of the products of urate oxidase (UAO)-catalyzed uric acid (UA) oxidation, a convenient method for the selective determination of UA was further developed with the help of UV–vis spectrophotometer. The increase of absorbance at 652 nm showed a linear response to UA concentration over the range of 2.0–180 μM. The limit of detection for UA was as low as 1.25 μM. More importantly, the proposed method was applied to the determination of UA in serum samples with satisfactory results.

ABSTRACT. The chemical constituents of the methanolic extract of Emex spinosa shoots were primarily characterized by gas-chromatography-mass spectrometry analysis (GC-MS), forty components were identified. The major components were ethyl 2-hydroxycyclohexane-1-carboxylate (10.11%), 3,5-dihydroxy-6-methyl-2,3-dihydro-4H-pyran-4-one (38.09%), 2-propyltetrahydro-2H-pyran-3-ol (5.75%), oleic acid (8.02%), and methyl (E)-octadec-16-enoate (5.91%). The results of antioxidant activity of leaves extract presented the most potent activity (IC50 = 29.92 mg mL-1), followed by stem extract (IC50 = 41.17 mg mL-1), and root extract (IC50 = 50.14 mg mL-1), comparable to that of the standard ascorbic acid (IC50 = 13.3 mg mL-1). The antibacterial results revealed that leaves extract is the most potent (22.0 mm) antibacterial agent against the variety of the tested species. Stem and leaves extracts are more potent (20 and 20 mm, respectively) than azithromycin (13.0 mm) against Pseudomonas aeruginosa species, while root and leaves extracts displayed potent antibacterial activities than tetracycline (10 mm). The most potent activity was recorded for leaves extract against Bacillus cereus species (22.0 mm) higher than the standard antibiotics (5.0-20.0 mm). The cytotoxic activity of E. spinosa MeOH extract specified the EC50 value at 2.68 µg mL-1 attended by a cytotoxic effect on HepG2 cell lines with the effective dose of the plant extract at a higher concentration.

Indicators and Dynamics of Formation A Healthy Lifestyle for Junior High School Students
Authors: Mong Yeng Chen
Published: November 2022

In the context of deep social and economic transformations in the country, the contradiction between the growing need of the society for active and healthy people and the catastrophic deterioration of children’s health becomes more acute. Complex studies show that the chronic pathology of schoolchildren is at an extremely high level. Against the backdrop of social insecurity, the problem of alcoholization and drug addiction of children and adolescents is growing, which poses a threat of moral decay to young people. Children’s health is affected by a number of negative factors: a decline in the standard of living in the country as a whole, a widespread deterioration of the environmental situation, and negative changes in the financial situation and the educational potential of the family. Unfortunately, the share of guilt for the current situation today is assigned to the school, which does not meet the modern requirements of hygiene and natural sciences of age physiology, causes disruption of adaptation, chronic fatigue of children and provokes the growth of diseases. Educational potential of school is considerably reduced: “...educational practice stays in a condition of influence on it of casual reference points, elements of positive, and even more negative, influences and uncontrollability”. In these conditions, the problem of maintaining health and education for a healthy lifestyle in schoolchildren is of particular interest to researchers. In the process of upbringing of children of primary school age the role of significant others - teachers and parents - is great. However, for the effectiveness of education for a healthy lifestyle is not enough readiness of the teacher, as the categories of lifestyle, lifestyle is largely associated with the family, with the way of life, with traditions, with the way of life of parents. Parents act as a role model for younger students, so in the process of upbringing important factors are personal, purely individual characteristics of parents, which include health status, physical culture, and attitude to health, culture of communication, ethical culture and experience of a healthy lifestyle.

Published: November 2022

The segment of wearable technology allows medical practitioners and nurses to be incredibly responsible for the patients who are interested in it. A lot of research analyses in this segment have been done which makes it essential for nurses to be significantly engaged in the promising technological advancement in the process of enhancing the lives of patients. In this paper, a synthesis of the present condition of wearable technology has been done. A brief evaluation of nursing satisfaction with medical technology has also been done based on the present research on wearable technology and its implications for the future state of nursing. It is therefore founded that other segments in the healthcare sector have applied wearable technology to enhance gait in patients suffering Parkinson’s illnesses which provides automated defibrillation in the cardiac patients. This has also enabled medical practitioners to effectively monitor post-stroke rehabilitation. The medical practitioners are also considered a front line for patenting and designing novel ideas to enhance the lives of patients. As such, nurses typically adopt the novel technologies such as electronic clinical administration records, electronic medical records and the simulation status in the sector of education. Wearable technological advancements consider the upcoming trend since its potential application is considered endless. Including the patients in their individual care is considered a potential obligation of nursing. In that case, more research evaluation is required to link-up patients with caregivers that benefit from the wearable technological advancements.

Results revealed that, majority of the Teachers performed the roles and functions in nine phases within the standards set by DepEd, while majority of them performed the roles and functions in three phases below the standards. Majority of the teachers performed well on their functions focusing on the preparation of learning resources, while majority of them performed not so well on their functions focusing on learning and student-centered and communication focus. With this result, gaps were identified in all phases of implementation, however, bigger gaps were noted in the three phases. In the light of this findings, the researcher proposes a model on the standard procedures in the delivery of Modular Instruction through HBL approach to effectively implement the same approach even after the pandemic for this approach could be used on inclement weather days and other unexpected natural calamities.
Morův Spirit of Nature a Newtonův éter
Authors: Joseph Jacques
Published: November 2022

The paper presents the notion of “Spirit of Nature” in Henry More and describes its position within More’s philosophical system. Through a thorough analysis, it tries to show in what respects it can be considered a scientific object (especially taking into account the goals of More’s natural philosophy) and in what respects it cannot. In the second part of this paper, More’s “Spirit of Nature” is compared to Newton’s various attempts at presenting a metaphysical cause of the force of gravity, using the similarities between the two to see this notorious problem of Newton scholarship in a new light. One thus sees that if Newton drew from Stoic and Neo-Platonic theories of aether or soul of the world, we need to fully acknowledge the fact that these substances were traditionally of a non-dualistic, half-corporeal, half-spiritual nature. Both More’s “Spirit of Nature” and Newton’s aether can thus be understood as different attempts at incorporating such a pneumatic theory into the framework of modern physics, as it was then being formed.
Werner Heisenberg, Niels Bohr a příběh kodaňské interpretace
Authors: Grygar Filip
Published: November 2022

The article focuses on the misleading story of the so-called Copenhagen interpretation of quantum mechanics. The interpretation was allegedly created as unitary or consistent and shared by its founders in 1927 by virtue of the so-called Copenhagen spirit of quantum theory. The paper is based on the role which two leading figures, Niels Bohr and Werner Heisenberg, played in this story. The first part of the article introduces variations of what is considered to be Copenhagen interpretation. The second part reveals that while quantum mechanics had originated in the 1920s, the Copenhagen interpretation was mainly a problematic Heisenbergʼs product of the 1950s. One of his main motivations for the introduction of Copenhagen interpretation was to set up a defence against increasing criticism of the supporters of quantum theory. Since there was no unitary or consistent interpretation of quantum mechanics among members of the so-called Copenhagen school, the last part of the paper focuses on several differences primarily between Bohr and Heisenberg’s interpretation.

Zdrojový kód jako literární technologie? O vytváření faktů v digitálním výzkumu
Authors: Hladík Radim
Published: November 2022

The increasing use of digital technologies in scientific work and communication raises the question of the epistemological nature of knowledge thus produced. In this essay, I am employing the conceptual apparatus developed by Steven Shapin and Simon Schaffer for the analysis of the historical dispute between Robert Boyle and Thomas Hobbes over the ways of producing knowledge in natural philosophy, and applying it to digital research. Their concept of three knowledge-making technologies – material, literary and social – appear to be heuristically useful concepts for reflecting on digital technologies as well. The latter are presented in the essay not as a separate facts-producing technology, but as elements around which the existing scientific technologies are radically reconfigured. Particular attention is paid to the concept of code as a literary technology and the role of digital technologies in the humanities.

Současné teorie sociálního rozumění na pozadí sporu a antropologickou diferenci
Authors: Jaroš Filip
Published: November 2022

Th is study is inspired by the book Jak rozumíme druhým? Studie o sociálním rozumění a sdílení světa nejen u člověka (How do we understand others? On social understanding and sharing of the world in humans and other animals) by Petr Urban and pays attention to current discussions about social cognition, namely in the case of non-linguistic agents. Most prominent positions are held by the group of comparative psychologists led by M. Tomasello, stemming from the philosophers of collective intentionality, and the group around D. Leavens and K. Bard, which is related to an interactivist interpretation of social cognition. It is demonstrated that the differences in the results of empirical studies are based on the ontological commitments of individual research programs, coupled with their relation to the problem of anthropological difference. The study questions the possibility of choosing a suitable theory by the means of the philosophy of science. At the end, a reinterpretation of non-human social cognition on the basis of umwelt theory is brought out.
Morální intuice z pohledu současné deskriptivní etiky
Authors: Chudárková Petra
Published: November 2022

In the last twenty years, there has been an enormous growth of scientific research concerning the process of human moral reasoning and moral intuitions. In contemporary descriptive ethics, three dominant approaches can be found – heuristic approach, dual-process theory, and universal moral grammar. Each of these accounts is based on similar empirical evidence combining findings from evolutionary biology, moral psychology, and neuroethics. Nevertheless, they come to different conclusions about the reliability of moral intuitions. The aim of this paper is to critically investigate each of these approaches and compare them with recent scientific findings. Last chapter addresses implications of these findings for moral epistemology and normative ethics. The aim is to show that despite different interpretations of available data, we can reach a satisfying pragmatical conclusion which would be in compliance with the empirical evidence, yet it would not necessarily depend on it.
How to Write a Proof: Patterns of Justification in Strategic Documents for Educational Reform
Authors: Wirthová Jitka
Published: November 2022

Writing strategic documents is a major practice of many actors striving to see their educational ideas realised in the curriculum. In these documents, arguments are systematically developed to create the legitimacy of a new educational goal and competence to make claims about it. Through a qualitative analysis of the writing strategies used in these texts, I show how two of the main actors in the Czech educational discourse have developed a proof that a new educational goal is needed. I draw on the connection of the relational approach in the sociology of education with Lyotard’s analytical semantics of instances in the event. The comparison of the writing strategies in the two documents reveals differences in the formation of a particular pattern of justification. In one case the texts function as a herald of pure reality, and in the other case as a messenger of other witnesses. This reveals different regimens of proof, although both of them were written as prescriptive directives – normative models of the educational world.
Genetic Diversity among Wild and Cultured Stocks of Sparus aurata on Turkish Mediterranean Coasts Revealed by Mitochondrial DNA Sequences
Authors: Dognakaya L. , Bekcan S.
Published: November 2022

The sequences of three mitochondrial DNA genes - 12S rRNA, cytochrome b, cytochrome oxidase II - were used to deduce genetic diversity and relationships among wild and cultured populations of gilthead sea bream (Sparus aurata) on Turkish coasts and coastal waters. The 415 bp of 12S rRNA, 605 bp of cytochrome oxidase II, and 557 bp of cytochrome b genes were sequenced and the data set was analyzed with Neighbor Joining and Minimum Evolution. Bootstrap analyses (1000 replicates) were performed and the relationships between samples are given in phylogenetic trees. Genetic diversity was estimated using gene diversity, number of haplotypes, and nucleotide diversity. There were no significant differences in variation in any of the three gene sequences. The maximum genetic variation occurred in cytochrome b (0.0050). Similarly, results showed very little divergence between sampling sites. Findings indicate a single wild population in the eastern Mediterranean, supporting the current classification that lacks subdivisions. Further, no differentiation between wild and culture stocks was inferred.
Modeling COVID-19 Infected Cases and Deaths Based on Generalized Method of Moments
Authors: Rajarathinam A. , Anju J.B.
Published: November 2022

Abstract

This paper investigates the dynamic relationships between the number of COVID-19 infected cases and deaths in all the districts of Karnataka state, India, from July 2020 to December 2021 based on the panel Generalized Method of Moments (GMM). The panel GMM model with the first difference transformation was found suitable for studying the dynamics of the number of deaths due to COVID-19 infections over time. The one-period lag (DEATHS (-1)) has a positive and significant effect on the number of deaths (DEATH). The Wald test confirms the validity of the coefficients' significance and adds explanatory power to the model. The correlation between number of fatalities at time t positively correlated with the number of deaths in the previous period. Also, the number of infected cases positively and significantly influences the number of deaths over time. Granger pairwise causality test reveals the existence of bi-directional causality relationships between the COVID-19 infected cases and deaths.

JEL classification numbers: E18, HO, I1, J64, J88.

Keywords: Arellano-Bond serial correlation test, Cross-sectional dependence test, Cointegration test, Granger causality test, Generalized Method of Moments, Kao cointegration test, Hausman test, Levin-Lin-Chu unit root test, Wald test.
