Post-marketing quality evaluation of oxytocin injection and assessment of associated factors among selected health facilities in Addis Ababa, Ethiopia

Oxytocin is the principal drug and the primary choice for labor induction and postpartum hemorrhage prevention and treatment. The problems associated with oxytocin are not usually from its effectiveness, but they are from its compromised quality which may occur at the point of manufacturing, transportation, and storage. The main objective of this study was to assess the status of oxytocin injection quality and associated factors in the health facilities located in Addis Ababa city, Ethiopia. A laboratory based instrumental quality testing alongside a cross sectional study design was used to evaluate oxytocin injection quality in Addis Ababa city administration from January to June, 2022 according to United States Pharmacopeia (USP 20), and the World Health Organization guideline of post-market medicine quality assessment. Binary logistic regression and cross tabulation analysis were conducted using SPSS 26. Significance was considered at p ≤ 0.05. Out of 107 tested oxytocin injection samples, 92.5% met the limit for oxytocin content, 81.3% for sterility test, and 91.6% for pH value. Overall, quality failure rate was 23.4%, while sterility test failure rate was 18.7%. Lack of reliable refrigerated storage condition [(AOR = 5.62, 95% CI: (1.87, 16.88)], lack of effective cold chain system during distribution [(AOR = 5.5, 95% CI: (1.53, 19.74)], and weak national medicine regulatory system [(AOR = 3.23, 95% CI: (1.13, 9.23)] were among the significantly associated factors for the failure of some of the brands. The study demonstrated that oxytocin injection quality failure rate, failing to meet at least one quality test requirement, is demonstrated in the health facilities of Addis Ababa. The determinant factors for the reported failures are related to storage, distribution, and regulatory system. Hence, these should be addressed by strictly adhering in to the national regulation and providing a comprehensive health promotion on rational use of oxytocin injection should be implemented to assure its quality and safety.

Myocarditis: Differences in Clinical Expression between Patients with ST-Segment Elevation in Electrocardiogram vs. Patients without ST-Segment Elevation.

In cases of myocarditis, electrocardiograms (ECGs) may suggest a pattern of ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI). NSTEMI patterns are less frequent in myocarditis cases, but it remains unclear if the presence of ST-segment elevation in myocarditis cases is related to a more severe condition and more damage in the myocardium. This is a retrospective study involving 38 patients admitted to hospital with myocarditis. Patients were divided into two groups: patients with ST-segment elevation (STE) patterns in the ECG (25), and patients without ST-segment elevation (non-STE) patterns (13). The data compared included results from epidemiological, laboratory, and instrumental tests. Data were analysed using IBM SPSS Statistics v26.0. A p value of <0.05 was established as the threshold for statistical significance. C-reactive protein (CRP) levels were higher in the STE group (103.40 ± 82.04 mg/L vs. 43.54 ± 61.93 mg/L, p = 0.017). The left ventricle ejection fraction (LVEF) was significantly higher in the non-STE pattern group (49.71 ± 4.14 vs. 56.58 ± 3.99, p < 0.001). A lower LVEF correlates with higher TnI levels (r= -0.353, p = 0.032) and higher CRP levels (r = -0.554, p < 0.001). Lower left ventricle (LV) strain correlates with higher levels of Troponin I (TnI) (r = -0.641, p = 0.013). LVEFs in the STE group were lower compared to those in the non-STE pattern group. STE pattern was associated with higher CRP levels. Higher TnI levels in cases of myocarditis were associated with lower LV strain and lower LVEF; higher CRP levels also correlated with lower LVEF. Based on a 6-month echocardiographic follow-up, the prognosis of myocarditis was favourable.

Opportunity or opportunism? Blockchain technology adoption and corporate default risk

Blockchain technology plays a significant role in new technology infrastructure and has a significant influence on artificial intelligence, big data, and 5 G, and its application has been extended to the Internet of Things, digital asset transactions, digital finance, and so on. In financial systems, it could improve the efficiency of data processing, reduce errors, and detect fraud. However, blockchain adoption could increase the stock price and induce manipulation opportunisms. Managers could also use this advantage to mask their performance and increase corporate default risk. Using the data of Chinese listed companies from 2001 to 2021, we investigate whether blockchain technology adoption could increase or decrease corporate default risk. Using the expected default risk model to estimate the risk, the results show that the default risk increases once the firm adopts blockchain technology, which indicates managerial opportunism behavior. The effect works in firms with CEO duality and higher power consolidation. And similar results are also shown in the dual-duty companies. The results are also robust in instrumental variable tests, difference-in-difference tests (DIDs), firm-fixed effect, placebo tests, and other robustness tests.

Oxidation of Geraniol on Vermiculite—The Influence of Selected Parameters on the Oxidation Process

Geraniol is a compound belonging to the group of monoterpenes that finds many applications in organic syntheses, medicine and cosmetics. The following properties of geraniol and its derivatives are of particular interest in medicine: its anti-inflammatory, antioxidant, antimicrobial and anticancer effects. The geraniol oxidation process was carried out using a mineral of natural origin—vermiculite. Vermiculite is a catalyst that perfectly fits into modern trends in the organic industry, where the aim is to use cheap, renewable and relatively easily available catalytic materials (vermiculite is found on continents including Africa, North America, South America, Australia and Asia). Preliminary studies on the oxidation process of geraniol on vermiculite was carried out in a glass apparatus using molecular oxygen supplied by means of a bubbler and magnetic stirrer with a heating function. During the oxidation process of geraniol on vermiculite, the influence of the following parameters was examined: the temperature, amount of catalyst and reaction time. The main parameters of the process, on the basis of which the most favorable process conditions were selected, were the selectivity of the transformation to 2,3-epoxygeraniol, citral and 2,3-epoxycitral, and the conversion of geraniol. The composition of the post-reaction mixtures was determined qualitatively and quantitatively using the gas chromatography method. In addition, vermiculite was subjected to instrumental tests, such as XRD, SEM, EDX, FTIR and UV-VIS. Moreover, the specific surface area, pore volume and pore volume distribution were estimated on the basis of N2 sorption at −196 °C and also the acid-site concentration in vermiculite was established.

THE MEDIATING EFFECTS OF ARTIFICIAL INTELLIGENCE LITERACY ON THE ASSOCIATION BETWEEN COMPUTATIONAL THINKING SKILLS AND ORGANIZATIONAL AGILITY AMONG SECONDARY SCHOOL TEACHERS

These days’ educational landscape forces teachers to adapt to changing demands and embrace innovations. In this study, Artificial Intelligence (AI) literacy was analyzed as how it mediates the association between Computational Thinking Skills (CTS) and Organizational Agility (OA) among secondary teachers. A quantitative causal mediation analysis design was utilized in this study. Standardized AI literacy test, CTS Test, and OA test instruments were utilized to gather pertinent data among 305 respondents. The test instruments were first subjected to confirmatory factor analysis for model fitness. Path and mediation analysis through structural equation modeling revealed that CTS significantly predicts AI literacy, AI Literacy significantly predicts OA, and CTS significantly predicts OA. It was found out that AI literacy partially mediates the relationship between CTS and OA among teachers. This recommends that schools should conduct a comprehensive training program to enhance teachers' CTS and AI proficiency for schools' sustained agility. Keywords: AI literacy, computational thinking skills, organizational agility, structural equation modeling, mediation analysis

Improving Grade Nine Students’ English Language Speaking Skill of Polite Requests: Misrak Chora Secondary School

Most commonly it is agreed that politeness is reflected in the pragmatic use of language. Although the politeness phenomenon is universal, with many expressional similarities, each language possesses norms and ways of expressing politeness within a given cultural context. Politeness has connection with everyday life such as with greeting, inviting, helping, apologizing, opinions, advice, questioning and suggesting information etc. English speaker tourists most frequently visit and resident in Hawassa City-Ethiopia and have cultural and communication exposure. However, many Ethiopian students are observed incompetent in this regard. Thus, the current study was intended to improve EFL learners’ polite requesting skills in some selected situations both in classroom contexts and outside contexts. For this purpose, the pre-experimental research design was employed to the study, and twenty students (10 females and 10 males) were randomly selected by lottery system from the 9&amp;lt;sup&amp;gt;th&amp;lt;/sup&amp;gt; B classroom. This makes 22.2% of the population in the class. Six politeness genres were selected from the students’ English textbook for explicit lesson intervention. Based on Written Discourse Completion Test (WDCT) instrument prepared from these contents, both pretest and posttest conditions were administered to the selected students. Also cooperative learning strategies such as role play, pair work, group discussion, extemporaneous speeches on situations, cooperative jigsaw, interactive discourse, timed interview, Think-Pair-Share (TPS) were utilized during the lesson sessions. Then, frequencies, means, standard deviations, variances and percentages were used to obtain the main findings. On pretest, students have scored the overall 27.16% (mean, 8.15) regarding all polite request situations. However, it was found that the posttest scores showed great difference about 78.3% (mean, 23.5) in all situations. The study has also sought which request contexts grade nine students improve best as a result of the explicit instruction. Although students have improved performance in all tested situations, they had showed very significant change on request for apology followed by for help. In apology situation the students have achieved 90% and the least in preference scenario which is 65%. Thus, it is recommended that learners have to be explicitly taught in context of these language genres to develop learners&amp;apos; communicative abilities in the area. Teachers should devote time to instruct on this language content [polite request] as it is everyday encounter in one&amp;apos;s life. Syllabus designers also should allot much time and tasks on the area so that school teachers give attention to areas.

Assessing Finger Flexor Pulley Injuries in Climbers: A Comprehensive Review of Clinical and Functional Testing Methods

Objectives: This systematic review addressed the following questions: what are the most recommended diagnostic criteria for pulley injuries in finger flexors among climbers? What is the best functional or classification clinical test for these injuries based on the available evidence? Materials and Methods: Following the PRISMA Statement checklist, a systematic literature review was conducted between August and September 2023, using a search on the PubMed database with a string of keywords and MeSH terms. The PEDro scale was used to analyze bias in the individual studies examined. Conclusions: Based on the exclusion criteria and research question, 14 articles with heterogeneous study designs were selected. Studies involving diagnosis through clinical examination or instrumental tests were analyzed. The data obtained provide an overview of different diagnostic and classification criteria for the injury under consideration. Ultrasounds remain the gold standard in diagnosing finger pulley injuries. The distance between the tendon and bone is the most used diagnostic criterion, with a distance greater than 2 mm corresponding to an A2 or A4 pulley injury. The clinical sign of bowstringing coincides with a multiple pulley injury involving A2, A3, and A4. Clinical signs, ultrasounds, and grip strength should be evaluated for a comprehensive diagnosis. A grip deficit of 41.4% corresponds to a pulley injury.

Robust Characterization of Photonic Integrated Circuits

AbstractPhotonic integrated circuits (PICs) offer ultra‐broad optical bandwidths that enable unprecedented data throughputs for signal processing applications. Dynamic reconfigurability enables compensation of fabrication flaws and fluctuating external environments, tuning for adaptive equalization and training of optical neural networks. The initial step in PIC reconfiguration entails measuring its dynamic performance, often described by its frequency response. While measuring the amplitude response is straightforward, e.g. using a tunable laser and optical power meter, measuring the phase response presents challenges due to various factors, including phase variations in test connections and instrumentation limitations. To address these challenges, a universal and robust characterization technique is proposed, which uses an on‐chip reference path coupled to the signal processing core (SPC), with a delay gap larger than the total delay across the signal processing paths. A Fourier transform of the chip's power response reveals the SPC's impulse response. The method is more robust against low reference‐path power and imprecise delays. Experiments using a finite‐impulse‐response (FIR) structure demonstrate rapid SPC training, overcoming thermal crosstalk and device imperfections. This approach offers a promising solution for PIC characterization, facilitating expedited physical parameter training for advanced applications in communications and optical neural networks.

Determination of uniaxial creep properties using equivalent factors by sharp indentation

The uniaxial creep properties, including the creep coefficient and stress exponent, are crucial to characterize the creep behavior of materials. Instrumented sharp indentation test (ISIT) is a non-destructive technique to characterize the uniaxial creep properties using the stress equivalent factor and strain rate equivalent factor. However, the strain hardening exponent of tested material is ignored in the contact model, leading to inaccurate estimation of uniaxial creep coefficient. Based on finite element simulations, the effects of the strain hardening exponent on equivalent factors were investigated. The relationships between the equivalent factors, the strain hardening exponent, and the yield strain were established. Indentation and uniaxial tests on Pb95Sn5 and Sn99Cu1 were conducted to validate the established equivalent factors. Then those factors were used to determine the uniaxial creep coefficient of Pb95Sn5 and Sn99Cu1 by ISIT. This work demonstrates the feasibility of measuring uniaxial creep properties of work hardened material by ISIT.

Optimization of Load-transfer Functions for a Large-diameter Pile in Multi-layered Geological Conditions via a Stochastic Search Algorithm

The paper presents the combination of the load transfer method (computational model) and the genetic algorithm (optimization model) for the automated inverse analysis of instrumented pile load tests. The output of this process are the input parameters governing the shape of the load-transfer functions and thus the prediction accuracy when the load-transfer method is used as a design tool for deep foundations. The optimization problem is converted into an unconstrained task by applying the static penalty approach. Two types of measurements are considered in a newly proposed objective function: the load-displacement curve monitored in a pile head and the axial force profiles along a pile derived from strain gauges. Firstly, the local sensitivity analysis via the Design of Experiments is carried out to identify the parameters of the genetic algorithm which significantly influences the rate of convergence during the optimization process. Subsequently, a fully automated inverse analysis of the loading test of the large-diameter bored pile in multilayered geological conditions is presented. The simultaneous combination of two instrumentation sources leads to a stable unique solution with a sufficient match between the prediction and measurements despite a larger number of unknown – optimized variables.

Performance of Recycled Opaque PET Modified by Reactive Extrusion

A comparative study of the structural integrity of an opaque recycled poly(ethylene terephthalate) (rPET-O) has been carried out with two types of modified rPET-O by applying reactive extrusion techniques, namely (a) using a multi-epoxide reactive agent (REx-rPET-O) and (b) a 90/10 (wt/wt) rPET-O/polycarbonate (PC) blend. The chemical modifications introduced during reactive extrusion were confirmed using differential scanning calorimetry (DSC) and rheological dynamic analysis (RDA). For the quantification of the fracture parameters, an instrumented pendulum impact testing machine was used using specimens in SENB configuration. The structural modifications generated during reactive extrusion promote an increase of between 16 (REx-rPET-O) and 20% (rPET-O/PC) in the stress-intensity factor (KQ) compared to unmodified rPET-O. The most significant differences between both modifications are registered in the “specific work of fracture” (wf) (alternative parameter to the standardized impact strength), where an increase of 61% is reached for the case of rPET-O/PC and only 11% for REx-rPET-O. This trend can be attributed to the type of reactive modification that is generated, namely chain branching (REx-rPET-O) vs. the generation of a random copolymer “in situ” (rPET-O/PC). This copolymer decreases the crystallization capacity and degree of crystalline perfection of rPET-O, promoting an increase in the critical hydrostatic stress conditions for the generation of crazing and crack propagation.
