Some results on the commutativity of prime near-rings using generalized derivations
Given a right near ring N, an additive mapping D: N →N is said to be a derivation on N, if D(xy) = D(x)y + xD(y) for all x, y ∈ N and an additive mapping F : N → N satisfying F(xy) = F(x)y + xD(y) for all x, y ∈ N, is called generalized derivation on N associated with the derivation D. The aim of this paper is to study the commutativity of a near-ring using some properties of generalized derivations on the given near-ring and we proved the following results. (a) The commutativity of 3-torsion free prime near-ring N with a generalized derivation F associated with non-zero idempotent derivation D on N satisfying the conditions F2[x, y] - [x, y] = 0 for all x, y ∈ N and F2(xoy) - (xoy) = 0 for all x, y ∈ N and (b) commutativity of 5-torsion free prime near ring N with a generalized derivation F associated with non-zero idempotent derivation D on N satisfying the conditions F2[x, y] + [x, y] = 0 for all x, y ∈ N and F2(xoy) + (xoy) = 0 for all x, y ∈ N are proved in this article. These results may help us to study more about the commutativity of general near-rings
Effect of repeated epilation for minor trachomatous trichiasis on lash burden, phenotype and surgical management willingness: A cohort study.
BACKGROUND: WHO endorsed the use of epilation as an alternative treatment to surgery for the management of both minor unoperated TT (UTT) and postoperative TT (PTT). However, some trachoma control programmes hesitated to implement epilation citing concerns that it would hamper TT surgical acceptance and result in larger numbers of and stiffer trichiatic eyelashes than the original TT lashes. We investigated the burden and phenotypes of post-epilation trichiatic eyelashes, and willingness to accept surgical management separately in unoperated and postoperative TT cases. METHODOLOGY/PRINCIPAL FINDINGS: We recruited cases with minor (≤5 eyelashes from the upper eyelid touching the eye or evidence of epilation in <1/3rd of the upper eyelid) UTT (170) and PTT (169) from community-based screenings in Amhara Region, Ethiopia. Participants eyes were examined and data on present and future willingness to accept surgical management collected at baseline and every month for 6-months. Eyelashes touching the eye were counted and their phenotypes documented. Participants were trained on how to epilate. Epilation was done by the participants at home and by the examiner during follow-ups when requested by the participant. Follow-up rates were ≥97%. There was evidence of a significant reduction in the burden of trichiatic eyelashes in unoperated (mean difference = -0.90 [-1.11- -0.69]; RR = 0.50 [95% CI, 0.40-0.62]; p<0.0001), and postoperative (mean difference = -1.16 [-1.36- -0.95]; RR = 0.38 [95% CI, 0.31-0.48]; p<0.0001) cases 6-month after frequent epilation. Post-epilation trichiatic eyelashes at 6-months had higher odds of being thin (40.2% vs 55.8%, OR = 1.88 [95% CI, 1.21-2.93]; p = 0.0048), weak (39.8% vs 70.8%, OR = 3.68 [95%CI,2.30-5.88]; p<0.0001), and half-length (30.9% vs 43.3%, OR = 1.71 [1.09-2.68]; p = 0.020) than the pre-epilation trichiatic eyelashes in unoperated cases. There was a significant increase in the proportion of weak trichiatic eyelashes (OR = 1.99 [95% CI, 1.03-3.83; p = 0.039) in postoperative cases. In all 6 follow-up time points, 120/164 (73.2%) of unoperated and 134/163 (82.2%) of postoperative cases indicated that they would accept surgery if their trichiasis progressed. CONCLUSIONS/SIGNIFICANCE: In this study setting, frequent epilation neither hampers surgical acceptance nor results in more damaging trichiatic eyelashes than the pre-epilation lashes; and can be used as an alternative to the programmatic management of minor unoperated and postoperative TT cases
Powell-Eyring nanofluid analysis with finite element method when past stretching sheet with convective heating and passive control of nanoparticle
Under this study, the boundary layer flow of the Eyring-Powell nanofluid past a stretched sheet with convective heating and passive nanoparticle control, the effect of nanoparticles on MHD was investigated. The governing equation is made up of a collection of nonlinear partial differential equations that have been constructed and transformed through similarity transformation into sets of nonlinear ordinary differentials of momentum, energy, and concentration. A nonlinear, high-order ordinary differential equation involving momentum, energy, and concentration that is subject to boundary conditions is then created as a result of the resulting pair. The Galerkin finite element method, a powerful numerical technique, is then used to numerically solve the problem. Grid independence/dependency was used to conduct the numerical solution for the finite element method result, and as a result, there is no variation in the result. Graphs are used to study and describe the effects of various parameters on velocity, temperature, and concentration profiles, while tabular data offers more in-depth information. The results show that as the velocity profile grows, both the magnetic parameter M and the Eyring-Powell fluid parameter K drop. For large amounts of the magnetic parameter M and the thermophoresis parameter Nt, the temperature and concentration profiles both showed an increment pattern, but a decrement pattern for increasing values of the Eyring-Powell fluid parameter K. Once more, the results demonstrate that for values of the magnetic field parameter and the thermophoresis parameter, the local Nusselt and Sherwood numbers are decreasing. In-depth information is presented using graphs and tabular data. The results of this study will offer insightful information about computational Powell-Erying nanofluids with MHD and pave the road for future finite element method implementation in software
Self-reported adverse drug reactions and their influence on highly active antiretroviral therapy in HIV infected patients: a cross sectional study
BACKGROUND: Patients on antiretroviral therapy have higher risk of developing adverse drug reactions (ADRs). The impact of ADRs on treatment adherence, treatment outcomes and future treatment options is quiet considerable. Thus, the purpose of this study was to describe the common self-reported ADRs and their impact on antiretroviral treatment. METHODS: Cross-sectional study was conducted at antiretroviral therapy (ART) clinic of Gondar University Hospital. Semi-structured interview questionnaire was used to extract self-reported ADRs, socio-demographic, and psycho-social variables. Variables related to antiretroviral medication, laboratory values and treatment changes were obtained from medical charts. Chi-square and odds ratio with 95% confidence interval were used to determine the associations of dependent variables. RESULT: A total of 384 participants were enrolled. At least one adverse drug reaction was reported by 345 (89.8%) study participants and the mean number of ADRs reported was 3.7 (±0.2). The most frequently reported ADRs were nausea (56.5%) and headache (54.9%). About 114 (31.0%) participants considered antiretroviral therapy to be unsuccessful if ADRs occurred and only 10 (2.6%) decided to skip doses as ADRs were encountered. Based on chart review, treatment was changed for 78 (20.3%) patients and from which 79% were due to documented ADRs (p = 0.00). Among them, CNS symptoms (27.4%) and anemia (16.1%) were responsible for the majority of changes. Around four percent of patients were non-adherent to ART. Non-adhered participants and those on treatment changes were not statistically associated with self-reported ADRs. Only unemployment status (AOR = 1.76 (1.15 - 2.70), p = 0.01) and ADR duration of less than one month (AOR = 1.95 (1.28-2.98), p = 0.001) were significantly associated with self-reported adverse effects of three or more in the multivariate analysis. CONCLUSION: Self-reported ADRs to antiretroviral therapy are quite common. More of the reactions were of short lasting and their impact on adherence and treatment change were less likely. However, documented ADRs were the most prevalent reasons for ART switch. Moreover, the level of unemployment was a strong predictor of self-reported ADRs
Home delivery among women who had optimal ANC follow-up in Sub-Saharan Africa: A multilevel analysis
Home delivery among women who had optimal ANC follow-up in Sub-Saharan Africa: A multilevel analysis.
BackgroundHome deliveries, where most births take place, are significantly responsible for the majority of maternal mortality. In order to develop appropriate policies and methods that could aid in addressing the issue, it is important to understand the scope of home delivery and its determinants in developing countries. Therefore, this study aims to ascertain the prevalence and factors associated with home delivery among women who had optimal ANC follow up in the Sub-Saharan Africa countries.MethodsA population based cross-sectional study was conducted. Data from the most recent Demographic and Health Surveys, which covered 23 Sub-Saharan Africa countries from 2014 to 2020, were used. The study used a total of 180,551 women who had optimal ANC follow up weighted sample. Stata 14 was used to analyze the data. The determinants of home delivery were determined using a multilevel mixed-effects logistic regression model. Factors associated with home delivery in the multilevel logistic regression model were declared significant at p-values ResultsIn Sub-Saharan Africa, three in ten (30%) women who had optimal ANC follow-up gave birth at home. Individual-level variables such as maternal age (20 to 35 years) (AOR = 1.27, 95% CI: 1.10, 1.46), no formal education (AOR = 3.10, 95% CI: 2.68, 3.59), pregnancy complications (AOR = 0.74, 95% CI: 0.67, 0.82), distance to a health facility (AOR = 1.43, 95% CI: 1.30, 1.58), and poor wealth status (AOR = 2.71, 95% CI: 2.37, 3.10) had higher odds of home delivery. Community-level variables such as rural residence (AOR = 2.83, 95% CI: 2.48, 3.22), living in central Sub-Saharan Africa (AOR = 7.95, 95% CI: 5.81, 10.9), and eastern Sub-Saharan Africa (AOR = 2.74, 95% CI: 2.09, 3.59), were significantly associated with home delivery.Conclusions and recommendationThis study concludes that home delivery in sub-Saharan Africa among women who had optimal ANC follow-up were high. The study identified that both individual and community-level variables were determinants of home delivery. Therefore, the Government and ministries of health in Sub-Saharan Africa countries should give attention to those women who reported distance as a big problem to health facilities and for rural resident women while designing policies and strategies targeting reducing home delivery in sub-Saharan Africa
Traditional bone setting service users and associated factors among people with trauma in Mecha district, Ethiopia
Abstract World Health Organization stated that traditional medicine is an important part of health care and countries need to consider integrating it into their primary health care system. Traditional bone setting has a long history in Ethiopia and it enjoys enormous acceptance in the community. However, these methods are raw, there is no standardized training and at the same time, complications are common. Therefore, this research aimed to assess the prevalence of traditional bone setting service utilization and associated factors among people with trauma in Mecha district. Methods A Community- based cross-sectional study design was employed from January 15 to February 15, 2021. A total of 836 participants were selected using a simple random sampling technique. Binary and multiple logistic regressions were employed to assess the association between the independent variables with traditional bone setting service utilization. Results The prevalence of traditional bone setting service utilization was 46.05%. Factors significantly associated with TBS utilization were: Age ≥ 60 years (AOR = 0.13, 95% CI: 0.03- 0.43), rural residence (AOR = 3.63, 95% CI: 1.76 -7.50), occupation (merchant (AOR = 0.21, 95% CI: 0.07 -0.61), and housewife (AOR = 4.12, 95% CI: 1.33 -12.70), type of trauma: dislocation (AOR = 6.40, 95% CI: 3.69–11.10), and strain (AOR = 2.09, 95% CI: 1.05- 4.14)), site of trauma: extremity (AOR = 0.20, 95% CI: 0.11, 0.37), trunk (AOR = 0.08, 95% CI: 0.03–0.22), and shoulder (AOR = 0.20, 95% CI: 0.11–0.37), cause of trauma: fall down and natural deformity (AOR = 9.87, 95% CI: 5.93–16.42) and household annual income greater than > 36,500 (AOR = 2.33, 95% CI: 1.29–4.22). Conclusion The prevalence of traditional bone setting practice is high in the study area, despite recent advancements in the practice of orthopedics and trauma in Ethiopia. Since TBS services are more accepted in society, the integration of TBS into the health care delivery system is recommended
Less than one in four mothers get quality intrapartum health care services in Ethiopia
Abstract Intrapartum care is a platform of comprehensive healthcare for pregnant women that is designed to improve birth outcomes for mother and child. However, complications during the intrapartum period continued to be the leading cause of death for women of reproductive age and newborns. Therefore, the aim of this study was to assess the prevalence of quality of intrapartum care and its associated factors among mothers in Ethiopia. A community based cross sectional study was conducted among 4469 mothers who gave birth in the last 2 years. Quality of intrapartum care was analyzed based on the assessment of health facility delivery, skilled birth attendants and early initiations of breast-feeding. Stata version 14 software was used for data cleaning and analysis. A mixed effect multilevel logistic regression was conducted to determine factors associated with quality of intrapartum care. An adjusted odds ratio with 95% confidence interval and a P value of less than or equal to 0.05 was used for the identification of both individual and community level factors. Overall, the prevalence of quality intrapartum care in Ethiopia was 23.8% (95% CI 22.6, 25.13). Primary education (AOR = 1.46, 95% CI = 1.14, 1.88), rich household class (AOR = 1.48, 95% CI = 1.10, 1.98), history of ANC (AOR = 2.91, 95% CI = 2.18, 3.86), perceived distance to the health facility as not a big issue (AOR = 1.63, 95% CI = 1.30, 2.05), urban residence (AOR = 2.97, 95% CI = 1.93, 5.09), Tigray region (AOR = 5.01, 95% CI = 1.25, 20.59), community level poverty (AOR = 0.63, 95% CI = 0.41, 0.97), and having 2–4 children (AOR = 0.74, 95% CI = 0.56, 0.97) were significantly associated with quality of intrapartum care. The finding conclude that less than one in four mothers received good quality intrapartum care. In order to optimize the quality of intrapartum care, the government should empower women through extensive education. It is also recommended for the Ministry of Health to evaluate the health facilities and community health workers to increase coverage of ANC and provide financial assistance to rural residents and the poor household class
Magnitude of optimal access to ANC and its predictors in Ethiopia: Multilevel mixed effect analysis of nationally representative cross-sectional survey.
BackgroundOptimal access to ANC, such as the first ANC visit at first trimester, four or more ANC visits, and skilled health care provider can significantly reduce maternal mortality in an inclusive way. Previous studies conducted in Ethiopia on optimal ANC are restricted to frequencies of ANC visit. Therefore, the aim of this study was to assess the magnitude of optimal ANC access as a comprehensive way and its predictors among pregnant women in Ethiopia.MethodsSecondary data source from a recent demographic and health survey was used for analysis. This study includes a weighted sample of 4771 pregnant women. A multilevel mixed-effect binary logistic regression analyses was done to identify both the individual and community level factors. Odds ratio along with the 95% confidence interval was generated to identify the predictors of optimal access to ANC. A p-value less than 0.05 was declared as statistical significant.ResultsIn Ethiopia, one in five (20%) pregnant women had optimal access to antenatal care. Regarding the factors at individual level, pregnant women aged 25-34 years [aOR = 1.58, 95% CI = 1.23-2.03] and 35-49 years [aOR = 2.04, 95% CI = 1.43-2.89], those who had educated primary [aOR = 1.67, 95% CI = 1.33-2.09], secondary and higher [aOR = 1.81, 95% CI = 1.15-2.85], Primipara [aOR = 2.45, 95% CI = 1.68-3.59] and multipara [aOR = 1.48, 95% CI = 1.11-1.98] had higher odds of accessing optimal ANC. With the community level factors, the odds of optimal access to ANC was higher among pregnant women who lived in urban area [aOR = 2.08, 95% CI = 1.33-3.27], whereas, lower odds of optimal ANC access among those pregnant women who reported distance to the health facility as a big problem [aOR = 0.78, 95% CI = 0.63-0.96].Conclusion and recommendationThe study concludes that in Ethiopia, optimal access to ANC was low. The study identified that both individual and community level factors were predictors for optimal ANC access. Therefore, the Ethiopian government should intensify extensive education on ANC in a comprehensive way. Moreover, especial attention from the Ethiopian ministry of health for those women who reported distance as a big problem and for rural resident women is mandatory
Prevalence and determinants of early neonatal mortality in Ethiopia: findings from the Ethiopian Demographic and Health Survey 2016
Background Early neonatal death accounts for a significant number of under-5 mortality worldwide. However, the problem is under-researched and under-reported in low-income and middle-income countries, particularly in Ethiopia. The magnitude of mortality during the early neonatal period and associated factors should be studied for designing appropriate policies, and strategies that could help tackle the problem. Hence, this study aimed to determine the prevalence and identify factors associated with early neonatal mortality in Ethiopia.Methods This study was conducted by using data from Ethiopian Demographic and Health Survey 2016. A total of 10 525 live births were enrolled in the study. A multilevel logistic regression model was used to identify determinants of early neonatal mortality. Adjusted OR (AOR) at a 95% CI was computed to assess the strength and significance of the association between outcome and explanatory variables. Factors with a p<0.05 were declared statistically significant.Results The national prevalence of early neonatal mortality in Ethiopia was 41.8 (95% CI 38.1 to 45.8) early neonatal deaths per 1000 live births. The extreme ages of pregnancy (under 20 years (AOR 2.7, 95% CI 1.3 to 5.5) and above 35 years (AOR 2.4, 95% CI 1.5 to 4)), home delivery (AOR 2.4, 95% CI 1.3 to 4.3), low birth weight (AOR 3.3, 95% CI 1.4 to 8.2) and multiple pregnancies (AOR 5.3, 95% CI 4.1 to 9.9) were significantly associated early neonatal mortality.Conclusions This study revealed a higher prevalence of early neonatal mortality as compared with prevalence in other low-income and middle-income countries. Thus, it is determined to be essential to design maternal and child health policies and initiatives with a priority on the prevention of early neonatal deaths. Emphasis should be given to babies born to mothers at extreme ages of pregnancy, to those born of multiple pregnancies delivered at home and to low birthweight babies
