Reproductive biology in the medicinal plant, Plumbago zeylanica L.

Plumbago zeylanica L. is an important medicinal plant traditionally used for the treatment of various diseases. Phenology from seed germination via vegetative growth to reproductive development wasstudied under glasshouse and nursery conditions. Seeds rapidly germinated on a mixture of nursery soil and cattle dung in a ratio of 3:1 filled in pots or on cultivated soil under nursery conditions as aprerequisite for vegetative and flowering phenological studies. Hypogeal germination characterizes the emergence of seedlings. Subsequent vegetative and flowering phenology between glass house andnursery field populations showed significant difference (

Effect of Knowledge Management on Organizational Performance in Addis Ababa, Ethiopia: A Case Study in Ethiopian Agricultural Trans-Formation Agency (Ata)

Knowledge management and knowledge resources have gained much importance in recent years and are said to improve organizational performance. However, the effects of knowledge management practices on organizational performance are not well known especially in the case of public organizations. This research had examined the effects of knowledge management practices on organizational performance at Ethiopian Agricultural Transformation Agency. The study adopted explanatory research. Questionnaires were adopted on the basis of literature review. The questionnaires were also used to collect data from members of staff; respondents were selected through a random sampling method with sample size of 140 respondents. The completed questionnaires were edited for completeness and consistency, checked for errors and analyzed using statistical package for social science (SPPS 20) frequencies, percentages and multiple correlations for quantitative analysis. The study recommends Ethiopian Agricultural Transformation Agency should ensure a formalized way of acquiring knowledge from its employee and implement knowledge sharing practices that enable the employees to learn from each other. Ethiopian Agricultural Transformation Agency should also revise Organizational structure in accordance with the knowledge management element to enhance the effect of organizational performance and use advanced technologies to enhance its knowledge management practice

An adolescent with significant emotional and medically unexplained complaints: case report and proposal of an intervention

Background: Ethiopia is a country in which child and adolescent mental health needs are often not met. In order to promote capacity building, a Collaborative International Exchange Programme has been established between Jimma University at Jimma, Ethiopia, and Ludwig-Maximilian University in Munich, Germany. The programme focuses on training non-physician health professionals in mental health speciality. One of the courses in the training programme, child psychiatry, involves a child psychiatrist and a children's nurse supporting the management of a patient described in this case report. Its conceptual framework is based on the section "significant emotional and medically unexplained complaints" of the "WHO mental health GAP intervention guide for mental, neurological and substance use disorders in non-specialized health settings". Objective: The purpose of this case report is to promote confidence in mental health professionals when managing patients with similar conditions, and to stimulate further evaluation of the conceptual approach in developing countries. Patient: The subject of this case report is a 14-year-old adolescent girl admitted to the psychiatric clinic at Jimma University Teaching Hospital. She was admitted for intractable retching, inability to eat, weight loss, and inability to walk. Challenges included the combination of medical and psychiatric symptoms, and the significant impairment of functioning in this adolescent. The first aim in the management of this patient was to guarantee vital functions. In a problem-oriented approach, different domains were addressed to restore nutritional, social, emotional, and motor functions. Treatment consisted of various elements of psychosocial interventions. The patient improved in 2 weeks and the final diagnosis was conversion disorder. Conclusion: Psychosocial interventions can be developed in cooperation, and applied in a setting where little child mental health expertise is available. Case-based learning relying on local expertise is suitable in meeting local needs and in developing mental health services for children and adolescents

Pneumococcal carriage, serotype distribution and risk factors in children with community-acquired pneumonia, 5 years after introduction of the 10-valent pneumococcal conjugate vaccine in Ethiopia

Background: There is a scarcity of data on pneumococcal serotypes carried by children in Ethiopia. We studied pneumococcal nasopharyngeal carriage rate, serotypes, and risk factors among children with community acquired pneumonia (CAP). Methods: A prospective observational cohort study was performed in children with CAP, aged 0-15 years, in 2 pediatric emergency departments in Addis Ababa, Ethiopia. Nasopharyngeal swabs were cultured, and serotypes of Streptococcus pneumoniae were determined by sequencing the cpsB gene and by the Quellung reaction. Risk factors were analyzed by using binary logistic regression. Results: Nasopharyngeal swabs were collected from 362 children with CAP. Pneumococcal carriage rate was 21.5% (78 of 362). The most common serotypes were 19A (27%), 16F (8.5%), and 6A (4.9%). In addition, 8.5% of the pneumococcal isolates were nontypeable. In bivariate analysis, children with a parent that smokes were more likely to carry pneumococci (crude odds ratio, 3.9; 95% confidence interval [CI], 1.2-12.3; P =.023) than those with parents that do not smoke. In multivariable analysis, living in a house with >= 2 rooms (adjusted odds ratio [AOR], 0.48; 95% CI, 0.28-0.82; P =.007) and vaccination with = 2 doses of 10-valent pneumococcal conjugate vaccine (PCV10) (AOR, 0.37; 95% CI, 0.15-0.92; P =.033) were protective of pneumococcal carriage. Conclusions: Five years after introduction of PCV10 in Ethiopia, the vaccine-related serotype 19A was predominant in the nasopharynx of children with CAP. Continued evaluation of the direct and indirect impact of PCV10 on pneumococcal serotype distribution in Ethiopia is warranted

Bacteremic community-acquired pneumonia in Ethiopian children : etiology, antibiotic resistance, risk factors, and clinical outcome

Background: Community-acquired pneumonia (CAP) remains a leading cause of morbidity and mortality. We sought to determine the magnitude, etiology, and risk factors of CAP in children 5 years after introduction of pneumococcal conjugate vaccine (PCV) 10 in Ethiopia. Methods: We conducted a prospective observational study on the bacterial etiology and risk factors of CAP among children aged 0–15 years in 2 pediatric emergency departments in Addis Ababa, Ethiopia. Blood culture, antibiotic susceptibility testing, and amplification of pneumococcal lytA and cpsB genes were performed. Serotypes of Streptococcus pneumoniae were determined by Quellung reaction and sequencing the cpsB gene. Results: Out of 643 eligible children, 549 were enrolled. The prevalence of bacteremic pneumonia was 5.6%. Staphylococcus aureus (26.5%) was the predominant pathogenic species, followed by Enterococcus faecium (11.8%), Escherichia coli (11.8%), and Klebsiella pneumoniae (11.8%). In univariate analysis, parental smoking and nonvaccination with PCV10 were associated with bacteremic CAP. In multivariable analysis, female sex (adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.1–4.9), weight-for-age z-score (WAZ) <–2 SDs (aOR, 2.2; 95% CI, 1.1–4.8), and lower chest indrawing (aOR, 0.44; 95% CI, 0.2–0.95) were independently associated with bacteremic CAP. The overall in-hospital case fatality rate was 2.37% (13/549), and WAZ <–3 SDs (OR, 13.5; 95% CI, 3.95–46.12) was associated with mortality. Conclusions: Five years after the introduction of PCV10 in Ethiopia, S. aureus was the main cause of bacteremic CAP in children, the contribution of S. pneumoniae was low, and there was a high level of antibiotic resistance among isolates

COVID-19 knowledge, attitudes, and vaccine hesitancy in Ethiopia : a community-based cross-sectional study

The current healthcare system’s efforts to reduce the spread of COVID-19 in Ethiopia and limit its effects on human lives are being hampered by hesitancy toward the COVID-19 vaccine. The aim of this study was to assess the knowledge levels, attitudes, and prevention practices of COVID-19, in the context of the level of vaccine hesitancy with other associated factors in Ethiopia. A community-based cross-sectional design with mixed-method data sources was employed. It comprised 1361 study participants for the quantitative survey, with randomly selected study participants from the studied community. This was triangulated by a purposively selected sample of 47 key informant interviews and 12 focus group discussions. The study showed that 53.9%, 55.3%, and 44.5% of participants had comprehensive knowledge, attitudes, and practices regarding COVID-19 prevention and control, respectively. Similarly, 53.9% and 47.1% of study participants had adequate knowledge and favorable attitudes toward the COVID-19 vaccine. Only 29.0% of the total survey participants had been vaccinated with at least one dose of vaccine. Of the total study participants, 64.4% were hesitant about receiving the COVID-19 vaccination. The most frequently reported reasons were a lack of trust in the vaccine (21%), doubts regarding the long-term side effects (18.1%), and refusal on religious grounds (13.6%). After adjusting for other confounding factors, geographical living arrangements, the practices of COVID-19 prevention methods, attitudes about the vaccine, vaccination status, perceived community benefit, perceived barriers toward vaccination, and self-efficacy about receiving the vaccine were significantly associated with vaccine hesitancy. Therefore, to improve vaccine coverage and reduce this high level of hesitancy, there should be specifically designed, culturally tailored health education materials and a high level of engagement from politicians, religious leaders, and other community members

Indigenous astronomical knowledge based seasonal weather forecast: evidence from Borana Oromo pastoralists of Southern Ethiopia [version 1; peer review: 2 approved, 1 approved with reservations]

Indigenous knowledge is still widely used by communities around the world to overcome social-ecological challenges. Borana Oromo pastoralists of Southern Ethiopia have been searching for future weather phenomena using their indigenous knowledge. This study examines indigenous knowledge-based seasonal weather forecasts through using observable physical and temporal patterns of astronomic objects. Data were generated through using focus group discussion, experimental knowledgeable groups and direct observation in the year 2021. The finding reveals that Borana Oromo pastoralists commonly define physical and temporal outlooks of the Moon that are changed and/ or displayed periodically within a range of varying contexts. The observation of the Moon features have been offering sufficient lapse time in a more than/within ahead of a season/ and is relatively more accurate than the other traditional forecasting objects. The study showed that both temporal and spatial dimensions of the forecasting were actually happened in Ganna (March to May rainfall), Adolessa dry season (June to September) and Hgayya rainfall (October to November) seasons of 2021. This indigenous weather forecasting practices are still regularly used in every livelihood decision making process. However, this indigenous weather knowledge of Borana Oromo pastoralists of Southern Ethiopia is not yet mainstreamed in the formal institutional structures. Curtailments of mobility, severity of drought, weakening of traditional institution, leaving of traditional life style and death of the knowledgeable elders are the major factors that are challenging the potential effects of the indigenous weather forecasting indicators of the features of moon in the study area

Khat chewing and its associated factors among pregnant women in Chiro district, eastern Ethiopia: a community-based study

IntroductionDespite its deleterious consequences, khat chewing is escalating worldwide. However, there is a lack of evidence about the extent of khat chewing among pregnant women in Ethiopia, particularly in the current study area. Therefore, this study aimed to assess the prevalence of current khat chewing and its associated factors among pregnant women in Chiro district, eastern Ethiopia.MethodsThis community-based cross-sectional study was conducted in Chiro district from November 1 to 30, 2022 G.C. Study participants were selected using the systematic random sampling technique. An interview-administered structured questionnaire was used to collect data through a house-to-house survey. The data were entered into EpiData version 3.1 and analyzed in STATA 14 software. Characteristics of study participants were summarized using descriptive analysis, and binary logistic regression was used to identify determinants of khat chewing.ResultsA total of 409 pregnant women participated in this study, with a response rate of 99%. The overall prevalence of khat chewing was 60.4% (95% CI: 55.5%, 65.2%). Religion (AOR: 2.08; 95% CI: 1.13, 3.82), khat cultivation (AOR: 0.43; 95% CI: 0.25, 0.77), partner khat use (AOR: 5.54; 95% CI: 3.11, 9.88), pre-pregnancy khat use (AOR: 9.95; 95% CI: 5.55, 17.81), antenatal care (ANC) visit (AOR: 2.71; 95% CI: 1.41, 5.21), and mental distress (AOR: 4.89; 95% CI: 2.38, 10.02) were significantly associated with current khat chewing.ConclusionThe majority of pregnant women in the study area practice khat chewing. Thus, accessible and comprehensive pre-conception and pre-natal care incorporating the prevention and management of antenatal khat chewing is crucial to overcome this problem. Provision of mental healthcare involving partners of pregnant women is also important to reduce the extent and impacts of khat chewing during pregnancy. Further longitudinal studies triangulated with qualitative designs are recommended

Nitrogen deficiency tolerance and responsiveness of durum wheat genotypes in Ethiopia

Development of low-nitrogen (N) tolerant and N-responsive durum wheat genotypes is required since nitrogen efficiency has emerged as a highly desirable trait from economic and environmental perspectives. Two hundred durum wheat genotypes were evaluated at three locations under optimum (ON) and low (LN) nitrogen conditions to screen genotypes for low-nitrogen tolerance and responsiveness to an optimum N supply. The results showed significant variations among the durum wheat genotypes for low-N tolerance and responsiveness. The average reduction in grain yield under the LN condition was 48.03% across genotypes. Only 17% of the genotypes tested performed well (grain yield reduction <40%) under LN conditions. Based on the absolute grain yield, biomass yield, and normalized difference vegetative index value, on average, 32, 14, 17, and 37% of the tested genotypes were classified as efficient and responsive, efficient and nonresponsive, inefficient and responsive, and inefficient and nonresponsive, respectively. Considering the absolute and relative grain yield, biomass yield, normalized difference vegetative index values, and stress tolerance indices as selection criteria, 17 genotypes were chosen for subsequent breeding. Among the screening indices, geometric mean productivity, stress tolerance index, yield index, and stress susceptibility index exhibited positive and significant correlations with grain yield under both N conditions; hence, either of these traits can be used to select low-N-tolerant genotypes. The common genotypes identified as LN-tolerant and responsive to N application in this study could be used as parental donors for developing N-efficient and responsive durum wheat varieties
