Full textAbstract:
A calendar of reproductive events is established in Eragrostis tef (Zucc.) Trotter, a sexual tetraploid Ethiopian cereal, using the microsporogenesis and microgametogenesis as reference scales to which the female gametophytogenesis is related. The absolute frequency is noted for each correlation brought out (microgametogenesis–megagametogenesis). The frequencies of all the female stages found at a same level of anther development are also specified. This preliminary work is done within the scope of an interspecific hybridization program which aims at transferring, to E. tef, genes responsible for the apomictic character present in the genus.

Full textAbstract:
The Ethiopian fruit fly (EFF), Dacus ciliatus, is a key, invasive pest of melons in the Middle East. We developed and implemented a novel decision support system (DSS) to manage this pest in a greenhouse environment in Southern Israel. Dacus ciliatus is commonly controlled in Israel with repeated calendar-sprayings (every 15 days) of pyrethroid pesticides. The current study compares the performance of a DSS against calendar-spraying management (CSM). DSS was based on EFF population monitoring and infestation. DSS took into consideration concerns and observations of expert managers and farmers. During 2014, EFF damage was concentrated in the spring melon production season. Fall and winter production did not show important damage. Damage during the spring of 2014 started to increase when average EFF/trap/day reached 0.3. This value was suggested as the threshold to implement pesticide spraying in DSS greenhouses. EFF/trap/day trends were derived from monitoring with conventional traps and a novel electronic remote sensing trap, developed by our group. CSM during the spring of 2015 included 3 EFF control sprays, while DSS-managed greenhouses were only sprayed once. At the end of the spring season, damage was slightly higher in DSS greenhouses (1.5%), but not significantly different to that found in CSM greenhouses (0.5%). Results support continuing DSS research and optimization to reduce/remove pesticide use against EFF in melon greenhouses. Interactions with farmers and managers is suggested as essential to increase adoption of DSS in agriculture.

Abstract This article deals with the fixed Christian Easter and the feasts, which depend on it. Both moveable and fixed feasts are recorded in Christian calendars and synaxaria. Following the decisions of the First Oecumenical Council of Nicaea (AD 325) the Ethiopians celebrated mostly the moveable Easter and its cycle. At the same time in the Ethiopian Royal Chronicles is also recorded that the Ethiopian Kings and their armies celebrated the fixed Easter and its festivals, especially the Good Friday.

"Patterns of Anthracycline-Based Chemotherapy-Induced Adverse Drug Reactions and Their Impact on Relative Dose Intensity among Women with Breast Cancer in Ethiopia: A Prospective Observational Study." Journal of Oncology 2020 (February 21, 2020): 1–12. http://dx.doi.org/10.1155/2020/2636514.
Full textAbstract:
Background. The breast cancer chemotherapy leads to diverse aspects of noxious or unintended adverse drug reactions (ADRs) that cause the relative dose intensity (RDI) reduced to below optimal (i.e., if the percentage of actual dose received per unit time divided by planned dose per unit time is less than 85%). Hence, this prospective observational study was conducted to evaluate chemotherapy-induced ADRs and their impact on relative dose intensity among women with breast cancer in Ethiopia. Methods. The study was conducted with a cohort of 146 patients from January 1 to September 30, 2017, Gregorian Calendar (GC) at the only nationwide oncology center, Tikur Anbessa Specialized Hospital (TASH), Addis Ababa, Ethiopia. The ADRs of the chemotherapy were collected using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) (version 4.03). The patients were personally interviewed for subjective toxicities, and laboratory results and supportive measures were recorded at each cycle. SPSS version 22 was used for analysis. Results. Grade 3 neutropenia (23 (15.8%)) was the most frequently reported ADR among grade 3 hematological toxicity on cycle 4. However, overall grade fatigue (136 (93.2%)) and grade 3 nausea (31 (21.2%)) were the most frequently reported nonhematological toxicities on cycle 1. The majority of ADRs were reported during the first four cycles except for peripheral neuropathy. Oral antibiotics and G-CSF use (17 (11.6%)) and treatment delay (31 (21.2%)) were frequently reported on cycle 3. Overall, 61 (41.8%) and 42 (28.8%) of study participants experienced dose delay and used G-CSF, respectively, at least once during their enrollment. Of the 933 interventions observed, 95 (10%) cycles were delayed due to toxicities in which neutropenia attributed to the delay of 89 cycles. Forty-four (30.1%) of the patients received overall RDI < 85%. Pretreatment hematological counts were significant predictors (P<0.05) for the incidence of first cycle hematological toxicities such as neutropenia, anemia, and leukopenia and nonhematological toxicities like vomiting. Conclusion. Ethiopian women with breast cancer on anthracycline-based AC and AC-T chemotherapy predominantly experienced grade 1 to 3 hematological and nonhematological ADRs, particularly during the first four cycles. Neutropenia was the only toxicity that led to RDI < 85%. Thus, enhancing the utilization of G-CSF and other supportive measures will improve RDI to above 85%.

"Application of behavioral economics principles to reduce injectable contraceptive discontinuation in rural Ethiopia: A stratified-pair, cluster-randomized field trial."

Full textAbstract:
Background: Contraceptive prevalence in Ethiopia jumped from 6% in 2000 to 36% in 2016, mainly due to increased injectable method use. However, discontinuation rates among injectable users were high (38%). Given that the public sector is the major source for injectable contraceptives, John Snow Inc. (JSI) in collaboration with ideas42 worked with Ethiopia’s flagship Health Extension Program to apply behavioral design to mitigate discontinuation of injectable contraceptives. Methods: We applied behavioral economics insights to mitigate the discontinuation of injectable contraceptives. This process created an intervention package, consisting of a health worker planning calendar, a client counseling job aid, and client appointment cards. A stratified-pair cluster-randomized field trial tested the effectiveness of the intervention. The study area included two districts from the four regions where JSI was implementing a family planning program. One district from each region was randomly allocated to the intervention arm. Women visiting health posts to use injectable contraceptives were enrolled in the study. Regression methods, adjusted for study design, participants’ backgrounds, and contextual factors, estimated the intervention’s effect on discontinuation rates. Results: A behavioral design methodology was feasibly implemented in a rural, low-resource setting in Ethiopia. The resultant intervention package was successfully delivered in 19 satellite health posts in four districts. Intervention adherence was high for the appointment cards and counseling job aid, but not for the planning calendar. The injectable discontinuation rate was 10.8 % (95% confidence interval: 2.2, 19.3) points lower in the intervention area compared to the control area during the post-intervention follow-up survey. Conclusion: The use of two tools informed by behavioral economics —the appointment card and counseling job aid—effectively decreased injectable discontinuation even with the presence of other health system bottlenecks. Behavioral economics insights and the behavioral design methodology have the potential to enhance family planning programs in Ethiopia and elsewhere.

(JSI) in collaboration with ideas42 worked with Ethiopia’s flagship Health Extension Program to apply behavioral economics informed approaches to mitigate discontinuation of injectable contraceptives. Methods: Behavioral diagnosis was conducted to identify the primary drivers of discontinuation of injectable contraceptives. Using these insights, a user-centered behavioral design approach was implemented to create an intervention package, consisting of a health worker planning calendar, a client counseling job aid, and client appointment cards. The study area included two districts from the four regions where JSI was implementing a family planning program. One district from each region was randomly allocated to the intervention arm.

Regression methods adjusted for study design, participants’ backgrounds, and contextual factors, were used to estimate the intervention’s effect on discontinuation rates. Results: Intervention adherence was high for the appointment cards and counseling job aid, but not for the planning calendar. This was not surprising as using appointment cards and the job aid was within the routine workflow of health extension workers, but using the planner was not. The injectable discontinuation rate was 10.8 % points lower in the intervention area compared to the control area during the post intervention follow-up survey. Conclusion: The use of two behavioral economics informed tools—the appointment card and counseling job aid—effectively decreased injectable discontinuation even with the presence of other health system bottlenecks. Behavioral economics approaches have the potential to enhance family planning programs in Ethiopia and elsewhere. Trial registration: ISRCTN ISRCTN17390653 (10/04/2019)

AbstractThis study examined men’s participation and performance in the Boston Marathon. Data from all 368,940 official male finishers in the Boston Marathon from 1897 through 2017 were analyzed using different analyses and regression models for all runners, annual top hundred finishers, annual top ten finishers and annual winners. Effect of calendar year on race time was examined alone, in a uni-variable model, and together with country of origin and weather conditions (average air temperature and precipitation) in a multi-variable model. The mean race time of all finishers increased across calendar years, in line with the participation, but it decreased when we considered the annual winners, 10 and 100 fastest. Kenyans and Ethiopians were the fastest nationalities (p<0.001) when we considered all finishers and the annual top 100 fastest but not when the annual 10 fastest were considered. Air temperature≤8 °C improved (p<0.001) race times compared to air temperature>8°C. Precipitation (>0 mm) improved performance for the annual 100 fastest and annual 10 fastest (p=0.013–0.031) but not for all finishers. Our findings improved the knowledge about the evolution of male marathoners across calendar years, considering as main effects country of origin and particular weather conditions.

AbstractObjectiveTo revisit seasonality by assessing how household diets vary across agricultural seasons in rural and urban Ethiopia. The role of seasonality on the sources and intake of energy (per capita) and household dietary diversity score (HDDS) was analysed.DesignThe use of nationally representative household-level data collected each month over one year to study the seasonal changes in the sources and intake of energy and HDDS.SettingEleven regions of Ethiopia, including rural and urban settings.SubjectsTotal of 27 835 households were interviewed between July 2010 and July 2011 in all eleven regions of the country. On average each month saw 2300 household interviews, yielding nationally representative data for each calendar month.ResultsFor rural households, the mean daily per capita energy intake was 10 288 kJ (2459 kcal) in February (post-harvest period) and lower in the lean season: 9703 kJ (2319 kcal) in June (P<0·05) and 9552 kJ (2283 kcal) in July (P<0·001). HDDS for rural households was highest in February (6·73) and lowest in June (5·98; P<0·001) but high again in July (6·57). Urban energy intake was also lower in the lean season but HDDS varied less by season. Considerable seasonal variation was also found in energy sources in rural areas, less so in urban areas.ConclusionsHousehold diets in Ethiopia remain subjected to significant seasonal stress. HDDS and food security measured using energy intake do not always agree. Preferably, HDDS and energy intake data should be used together to assess food security.

Full textAbstract:
This study examined smallholder farmers’ perception about climate change and variability compared with the observed metrological data and their adaptation strategies in response to the perceived impacts of climate change. The multistage sampling method was employed to select 358 rural farmers in Hawzen and Irob districts located in semiarid highlands of Eastern Tigray, northern Ethiopia. Moreover, areal gridded surface monthly rainfall and temperature data between 1983 and 2015 were collected from National Meteorology Agency of Ethiopia. The results revealed that about 98.56 and 92 percent of farmers perceived a decrease in annual rainfall. In addition, 87 and 90 percent of farmers noticed that temperature was increased in Hawzen and Irob districts, respectively. Harmoniously, the modified Mann–Kendall trend test confirmed that annual rainfall was decreased by 32.38 mm and 121.33 mm during the period of analysis. Furthermore, mean annual temperature increased statistically significant (p<0.001) by about 0.40°C and 0.39°C per decade during the period of analysis cognate with the farmers’ perception. To reduce the perceived impacts of climate change, farmers adopted various farm-level adaptation strategies that vary significantly between the two groups. Soil and water conservation, planting trees, crop varieties, changing crop calendar, biological conservation, and irrigation were among the dominant adaptation strategies, respectively, in the study area. The results of this study provide baseline information for local governments, subsequent researchers, and policy-makers in terms of farmers’ perception of climate change and adaptation strategies.

Full textAbstract:
Abstract The contribution of beekeeping is perhaps one of the most important income-generating activities for millions of smallholder farmers in Ethiopia. This study was intended to assess beekeeping practices and potential in three districts of Afar Region, northern Ethiopia. Primary data were collected from 120 respondents proportionally selected from each district. Semi-structured questionnaire were employed to collect the primary data. Focus-group discussion was also used to support interpretation of the interview data. Basically, descriptive statistics were used to analyse the data. All respondents use traditional honey production system despite some recent trials. The mean live colony ownership of the sample beekeepers is 10.08 colonies per household, with a maximum ownership of 62 colonies. The study showed that the annual honey production per beehive varies from 4 to 17 kg, with a mean production of 9.66 kg. The majority of the respondents harvest two times per year, while 18%, 19%, and 14.2% of the respondents harvest three, four, and five times per year respectively. This might be due to the special floral calendar of tropical plants found in the areas. 67.5% of respondents supplement their colonies during dry season. Producers travel more than seven kilometres to sell their honey. On average, beekeepers sell 77.86 kg per year individually, with a range of 0 to 353 kg. The main constraints of honey production in the area are recurrent drought, poor extension service, lack of access to improved technology, deforestation, etc. Therefore, it requires intervention to change the old beekeeping practices through training and introducing improved production systems.
