Comparative Evaluation of Clinical, Endoscopic and Histopathological Findings of Helicobacter Pylori-Associated Gastroduodenitis in Children

Background: Chronic colonization with Helicobacter pylori (Hp) has been shown to significantly increase the risk of gastric ulcer and duodenum as well as chronic gastritis in children and adults. Due to the importance of early detection and treatment of HP infection especially in children, this study aimed to compare the clinical, endoscopic and histopathological findings in children with HP gastroduodenitis and control group. Materials and Methods: In this cross-sectional study, all children referred to the gastroenterology clinic of children´s hospital, Qazvin, Iran, between 2016 and 2018, with a history of gastrointestinal complaints underwent upper gastrointestinal endoscopy if necessary, then tissue samples were taken, and rapid urease test was performed. Subsequently the patients were divided into two equal groups of 200: HP positive (patient group), and Hp negative (control group). Results: The mean age in the Hp positive group and in the control group was 8.11±3.68 and7.22±2.96 years, respectively (P<0.05). The most common clinical manifestation in the Hp positive group was chronic abdominal pain (n=66, P<0.001). Endoscopic examinations revealed that the evidence of mucosal erythema, erosions and nodular mass of the corpus, antrum and bulb were significantly higher in Hp positive group. Histopathologic studies also showed more evidence of corpus, antrum and bulb inflammation in the Hp positive group compared to the control group. Conclusion: Overall, based on the results of this study, it seems that endoscopic evidence of mucosal appearance of erythema, obvious nodularity and mucosal erosion in the corpus and antrum as well as bulb of duodenum in children with HP gastro- duodenitis has a diagnostic value.

SiO2 particles effect on the mechanical properties of the starch/PVA blends

The present work studies the mechanical properties of SiO2 μPs, and NPs in St/PVA blends. The samples were prepared by casting method as PVA, St/PVA blends at different concentrations (30, 40, 50, and 60 %). DSC and TGA tests were carried out to the samples evolved. The result showed a single glass transition temperature (Tg) for all St /PVA blends that was attributed to the good miscibility of the blends involved. It was found that (Tg) decrease with starch ratio increase. It was seen that (PVA) of (Tg=105 oC); The glass transition temperature which was decrease with starch ratio that was attributed to glass transition relaxation process due to micro-Brownian motion of the main chain back bond. The endothermic peak at 200 oC was attributed to melting point of (PVA). Thermal properties of PVA; and St /PVA blends at different concentration (30, 40, 50, and 60 %) were evaluated by thermo gravimetric analysis (TGA). The analyses were carried out from 20 to 600 oC at 10 oC)/min heating rate in air oxygen atmosphere. The weight loss stages depended on polymer system. The starch addition causing shifting in the second degradation temperature to the higher temperature; which result in overlapping between the two main degradation steps, these result was attributed to the St/ PVA blend compatibility. The mechanical properties results showed a decrease in ultimate strength with starch ratio increase. The ultimate strength of (PVA) was (47 MPa), whereas the ultimate strength of 60 %St/PVA was (11 MPa) and for 30 %St/PVA was the highest ultimate strength of blends involved (26 MPa). SiO2μPs (753.7 nm), and NPs (263.1 nm) were added at different concentrations (1.5, 2, and 2.5 %). 1.5% SiO2μPs, and NPs of the best ultimate strength (69 MPa), (86 MPa) respectively then it was decreased by SiO2μPs, and NPs increase. Optical microscope of the samples involved was investigated. It was concluded the prepared samples were suggested to be used as packaging materials for agriculture application and its ultimate strength could be controlled by SiO2μPs, and NPs addition.
Research Paper: Comparing Prophylactic Effect of Rivaroxaban and Enoxaparin on Thromboembolism After Total Hip or Knee Arthroplasty

Background: Vascular thromboembolism is one of the major concerns of orthopedic surgeons after hip or knee replacement surgery. Although many thromboprophylactic drugs have been introduced, there is still no consensus over their efficacy and safety. Therefore, this study aimed to compare the efficacy and safety of oral rivaroxaban and aspirin administration and enoxaparin injections in patients undergoing knee or hip replacement. Objectives: Determination and comparison of the side effect and efficacy of Rivaroxaban and Enoxaparin after total hip or knee arthroplasty. Methods: A total of 231 patients undergoing knee or hip replacement surgery were included in the study. Of them, 31 patients were excluded due to missing the follow-up. Of the remaining 200 patients, 42 low-risk and 158 moderate- to high-risk patients were identified, according to Caprini risk assessment model. Then, they were divided into three groups: aspirin (42 patients), enoxaparin (78 patients), and rivaroxaban (80 patients). Severe hemorrhage (hemoglobin reduction of more than 2 g/dL or requiring blood transfusion) was assessed after the first dose of medication until discharge through daily hemoglobin testing. Frequency of other side effects such as wound complications (ecchymosis, hematoma, and wound infection) and gastrointestinal or skin problems was recorded and compared by daily examination during the hospital stay and then in the future visits to the clinic up to 6 months in each group. Follow up visits were performed at weeks 6, 12, and 24. Results: No cases of deep vein thrombosis or pulmonary thromboembolism were observed in any of the study groups. There was no significant difference between the two groups in the number of major bleeding cases (P=0.39). Ecchymosis around the wound was significantly higher in the rivaroxaban group than in the enoxaparin group (33.8% vs. 23%). However, this difference was not statistically significant (P=0.06). Conclusion: The efficacy and safety of rivaroxaban and enoxaparin drugs are comparable. Although ecchymosis was seen after using rivaroxaban rather than enoxaparin, rivaroxaban is orally administered and costs less for the patient and the health system. So, its use as a thromboprophylactic drug of choice following hip and knee arthroplasty surgery is still recommended. http://dx.doi. org/10.32598/JROS.7. 1.13
Bioinformatics analysis of the regulatory lncRNA-miRNA-mRNA network in patients with neuropathic pain and prediction of potential therapeutics

Background: Neuropathic pain (NP) is the main form of chronic pain, caused by damage to the nervous system and dysfunction. Here, we aimed at exploring the key molecules involved in NP pathogenesis via the identification of its regulatory lncRNA-miRNA-mRNA network.Methods: We downloaded NP-related data from public databases and identified differentially expressed long noncoding RNAs (lncRNAs), microRNAs (miRNAs) and mRNAs through differential gene expression analysis. The lncRNA and miRNA target predictions were performed and an integration of the three datasets was used for construction of the lncRNA-miRNA-mRNA network. Subsequently, functional enrichment analysis and protein-protein interaction (PPI) analysis were performed to explore the role and the interactions of the mRNAs. The drug prediction was performed based on the mRNAs in the lncRNA-miRNA-mRNA network. Results: A total of 8,251 differentially expressed mRNAs (4,193 upregulated and 4,058 downregulated), 959 differentially expressed miRNAs (455 upregulated and 504 downregulated), 2,848 differentially expressed lncRNAs (1,324 upregulated and 1,524 downregulated) were identified by integrating the results of the three microarray datasets. We found that differentially expressed mRNAs were mainly enriched in blood circulation, metal ion transmembrane transporter activity, and synaptic membrane. The most significant pathway of mRNAs in lncRNA-miRNA-mRNA network were GTPase, cell cycle, and platelet activation. A total of 1,200 drugs were predicted as potential therapeutics for NP based on the regulatory genes.Conclusion: Our study predicted drugs that may be effective for NP based on the NP regulatory network. This information will help further reveal the pathological mechanism of NP and provide more treatment options for NP patients.
Improvement in oral function after an oral exercise program including whole-body exercises

Objectives: To evaluate the impact of an oral exercise program including whole-body exercises on oral function in older people. Methods: The participants (aged ≥65 years) were divided into three groups: intervention group I (only oral exercise), intervention group II (oral exercise with wholebody exercises), and control group (no intervention). The oral health status, saliva flow rate, and oral muscle strength were evaluated. Analyses were performed to compare the three groups and identify the changes in the aforementioned parameters before and after the program. Results: The saliva flow rate significantly increased in intervention groups Iand II after the program. Oral muscle strength evaluation using the Iow a oral performance instrument showed that the anterior tongue strength increased significantly in intervention group I; the posterior tongue strength and cheek strength also increased but not significantly. The anterior tongue, posterior tongue, and cheek strengths significantly increased in intervention group II. Conclusions: The oral exercise program including whole-body exercises showed positive effects on the saliva flow rate and oral strength. No significant differences were observed in the quality of life related to oral health.
Financial Assessment of Banks and Financial Institutes in Stock Exchange by Means of an Enhanced Two stage DEA Model

A stock exchange is an entity which provides ‘‘trading’’ facilities for stock brokers and traders to trade stocks and other securities. How to invest in stock exchange is one of the important issues in investment, and one of the factors that can help investors in the process of investment is the efﬁciency of the corporation under consideration. Data envelopment analysis is a mathematical methodology that has been widely applied to assess the performance of banks and financial institutes. The main feature of this method is that this methodology evaluate firms by considering multiple inputs and outputs. Conventional DEA models consider each firms as black box and don’t note into the inner activities. Two-stage data envelopment analysis has been researched by a number of authors that evaluate each firm by considering the inner operations. This paper proposes a new two stage BAM model and further evaluates the banks and financial institutes in Tehran stock exchange by considering the financial ratios. Conventional DEA models consider each firms as black box and don’t note into the inner activities. Two-stage data envelopment analysis has been researched by a number of authors that evaluate each firm by considering the inner operations. This paper proposes a new variant of two stage DEA models and further evaluates the banks and financial institutes in Tehran stock exchange by considering the financial ratios.
Factors Affecting a Medical Faculty’s Engagement in Virtual Learning Environments

Background: This study aimed to investigate the intrinsic and extrinsic factors affecting faculty engagement in virtual learning environments at Shiraz University of Medical Sciences (SUMS) in Shiraz, Iran. Methods: In this comparative study, 112 eligible faculty members at SUMS were enrolled in 2018-2019 academic year. The sample was surveyed by a researcher-made questionnaire consisting of 28 items, including 17 questions on intrinsic factors (familiarity with e-learning, faculty attitudes and human resources) and 11 on extrinsic factors (financial resources, inherent barriers, infrastructural factors and institutional support). The reliability of the research instrument, as measured by internal consistency and Cronbach’s alpha, stood at 0.92. It was measured at 0.87 and 0.92 for extrinsic and intrinsic factors respectively. The CVR and CVI values were found to be 0.6 and 0.8 respectively. One-sample t-test was applied to compare the mean scores of the intrinsic and extrinsic factors with the hypothetical mean, and to determine the ranking of the factors. Results: In order of their impact, the intrinsic and extrinsic factors included inadequate financial resources (P=0.566) lack of familiarity with electronic learning (p <0.001), inherent barriers such as institutional disbelief in the complementary role of e-learning (P=0.001), infrastructural factors (p <0.001), faculty attitudes (p <0.001), inadequate human resources (p <0.001), and lack of institutional support (p <0.001). Conclusion: University administrators should provide educators with adequate resources for handling new educational environments, remove administrative and structural obstacles, and create motivation among faculty members to use e-learning systems.
Magnetic porous Fe-C materials prepared by one-step pyrolyzation of NaFe(III)EDTA for adsorptive removal of sulfamethoxazole

A series of magnetic porous Fe–C materials were prepared by one-step pyrolyzation of ethylenediaminetetraacetic acid sodium iron(III) at 500°C–800°C and then employed as adsorbents for sulfamethoxazole (SMX) adsorption. The one prepared at 700°C (Fe–C-700) was selected as the optimum one with an adsorption amount of 82.3 mg g–1 at pH 5.0 and 30°C. This was mainly ascribed to its higher surface area which offered more space for hydrophobic and electron donor–acceptor interactions between SMX and its surface. The adsorption kinetics was analyzed with three models. With the increase of concentration, the k1 value decreased from 0.383 to 0.329 min–1, and the k2 value decreased from 0.0292 to 0.0101 g mg–1 min–1. The thermodynamic analysis showed that SMX adsorption on Fe–C-700 was a spontaneous exothermic entropy-decreasing process. The effects of adsorbent dosage, pH, metal ions and humic acid on SMX adsorption were also investigated. The spent Fe–C-700 could be easily separated and recycled after adsorption due to its magnetic feature.
Predictors of Spontaneous Conception Following Myomectomy among Women with Infertility at Federal Medical Centre Yenagoa, Nigeria

 Background: Uterine fibroid or leiomyoma (myoma) is the commonest uterine neoplasm in women, and it has been associated with infertility. Though it’s not regarded as a direct cause, surgical removal (myomectomy) has been reported to increase the spontaneous conception rate in women with infertility.  Objective: The objective of this study was to determine the factors associated with conception after myomectomy in women with infertility. It would determine the pregnancy rate, demographic, and surgical factors (pre and postoperative factors).  Materials and Methods: This was a retrospective observational study of 107 women who had myomectomy during the study period, out of these, 68 were done for infertility. The case notes of these women were retrieved, and information related to demographic factors obtained was: maternal age, parity, address, tribe, educational level, and occupation. The Original Research Articles Howells et al.; IJTDH, 42(3): 32-45, 2021; Article no.IJTDH. 66354 33 preoperative surgical factors obtained were previous history of myomectomy, indication for myomectomy, the size, number and location of myomas, and the caliber of the surgeon. Postoperative surgical data collected include conception, interval between myomectomy and conception, pregnancy outcome, mode of delivery, and fetal sex and birth weight. Categorical variables were compared with chi square and odds ratio, and the degree of association for quantitative variables was determined using Pearson’s correlation coefficient. Predictor variables were determined using simple logistic regression, and multivariate analysis.  Results: The infertility rate among the women who had myomectomy was 63.6%, the conception rate was 14.7%, and the mean myomectomy to pregnancy interval was 9.20 ± 1.24 months. The factors that favor conception were: younger women P = 0.003, uterine size ≤ 16 weeks odds ratio = 3.50(0.14, 84.20), high parity (p = 0.002), solitary fibroid odd ratio = 2.65(0.44, 16.04), tertiary education P = 0.0001 and surgery by consultants P = 0.004. Others were absence of submucous myomas, and pelvic pathology at laparotomy. Using multivariate analysis, the most significant predictors for conception were age and parity, accounting for 10.7%, and all the factors put together could only explain 36.5%.  Conclusion: The conception rate following myomectomy in Yenagoa was relatively low, and the most important predictors were maternal age and parity. The bulk of the factors (65.5%) that determine conception are outside the scope of our study; these could be male factor infertility, factors within the tubal lumen, unidentified uterine synechia, and ovarian failure.
The Effect of Economic Growth on Employment in GCC Countries

The objective of this research is to analyze the employment intensity of growth in six Gulf Cooperation Council countries between 1970 and 2017. To this end, a two-step econometric methodology is proposed. First, we estimate the time-varying employment intensity of growth using the time-varying parameters model based on the Kalman filter. Second, we identify the short and long-run determinants of the obtained employment intensity of growth using the Pooled Mean Group estimator. The analysis uncovers that elasticities range between 0.4 and 0.6 and has an increasing pattern over time. Findings reveal that in the long-run, the employment intensity is positively affected by trade liberalization, the share of services in GDP, the working-age population growth, and urbanization, while macroeconomic volatility has a negative impact. In the short-run, trade liberalization and natural resource rents exert adverse but weak effects on employment intensity. Based on these findings, some policy recommendations are drawn.
Antecedents and Consequences of Attitude toward Femvertising

As femvertising has raised a great deal of attentions in Korea and abroad, femvertising which focuses on women’s equality and empowerment has also brought much pubic attentions. Despite of much attentions, research on femvertising has been scarce. Thus, this study is designed to examine antecedents and consequences of attitude toward femvertising. For antecedents, this study proposes perceived congruence and perceived authenticity; as consequences, it proposes attitude toward brand, purchase intention, and e-word-of-mouth intention. A total of 278 college students participated in the study in return for course credits. Study results suggest that both perceived congruence and perceived authenticity are positively related to attitude toward advertising. In sum, when consumers perceive that femvertising messages are congruent with the company’s brand image and the ad messages are authentic, positive attitude toward ads is likely to increase. Findings also suggest that attitude toward femvertising is positively related to attitude toward brand, purchase intention, and e-word-of-mouth-intention. In the last section of this paper, we discuss theoretical and practical implications. ■ keyword :∣Femvertising∣Congruence∣Authenticity∣Attitude toward Brand∣Purchase Intention∣e-word-of-mouth∣ 접수일자 : 2020년 09월 03일 수정일자 : 2020년 10월 20일 심사완료일 : 2020년 11월 09일 교신저자 : 엄남현, e-mail : goldmund@hongik.ac. kr 펨버타이징 광고 태도의 선행요인 및 결과 연구 67
Factors Affecting the Adoption of a Formal Accounting System in Small and Medium Enterprises with Special Reference to Anuradhapura District

Small and Medium Enterprises (SMEs) are the most important category in an economy as they contribute to the economic development by generating employment opportunities and consumer’s essential goods and services. But long term survival and success of SMEs is dependent on their ability to maintain a proper accounting system. But most of the SMEs have not adapted to maintaining an accounting system. The main purpose of the study is to identify factors which affect the adoption of a formal accounting system in Small and Medium Enterprises with special reference to Anuradhapura district. In the present study, one dependent variable and five independent variables are considered. The results suggest that financial accounting practices, owner/manager knowledge and size of the business have significant positive impacts on the adoption of a formal accounting system, while age of the firm and external pressure have insignificant positive impacts on the adoption of a formal accounting system by SMEs. A selfadministered questionnaire was developed and disseminated to eighty respondents, and they were considered for further statistical analysis. The data were analyzed and hypotheses were tested through descriptive statistics, correlation analysis and regression analysis. However, the small sample size raises the issue of generalization, which future studies should seek to address. Further, the study recommends that SMEs can get the most benefits by adopting a formal accounting system, and accredited authorities should design specific guidelines for SMEs accounting and provide templates for accounting practices of SMEs.
Crystalloid Fluid Pre-loading or Co-loading for Prevention of Spinal Anesthesia Induced Hypotension at Gandhi Memorial Hospital, 2016 Addis Ababa, Ethiopia: Comparative Cohort Study

Introduction: Caesarean section is a common procedure done in hospitals including in Ethiopian hospitals. Spinal anesthesia remains the preferred choice for Cesarean deliveries across the world with a low failure rate. However spinal anesthesia-induced hypotension is the commonest complication and the incidence ranges from 53.3% to 83%. Objectives: To compare the preventive effect of crystalloid fluid preloading and co-loading for spinal-induced hypotension and its incidence, severity, and use of vasoconstrictors in obstetric mothers undergoing cesarean section at Gandhi Memorial hospital 2016 Addis Ababa, Ethiopia. Methods: Cohort study design was used with a total of 96 mothers (48 of them preloaded and 48 of them coloaded with 1000 ml ringer lactate) involved in the study. Preoperative and other variables filled on the questioner than the Blood Pressure measured on an anesthesia monitor every 5 and 10-minute intervals till 60 minutes after spinal anesthesia was given. The data inter into EPI info and SPSS then finally analyzed with student T-test, chi-square or Fisher exact test and P value less than 0.05 declared as statistically significant. Results: Incidence of spinal anesthesia-induced hypotension was high in the preload group 81.2% (39/48) and low in coload group 35.4% (17/48) and the result is statistically significant. Frequent Episode and more sever spinal anesthesia-induced hypotension were also common in the preload group. Conclusion: Crystalloid fluid coloading to the operating mothers during the cesarean section was a better option for the prevention of spinal anesthesia-induced hypotension.
