COVID-19 Vaccine Hesitancy and its Reasons in Addis Ababa, Ethiopia: A Cross-Sectional Study

BACKGROUND: Coronavirus disease (COVID-19) vaccine hesitancy becomes the major bottleneck to the global healthcare system in minimizing the spread of the virus. This study aimed at assessing COVID-19 vaccine hesitancy and its reasons among residents of Addis Ababa, Ethiopia. METHODS:  A community-based cross-sectional survey was conducted between May 16 to 29, 2021 in purposively selected four districts of Addis Ababa, Ethiopia. A structured questionnaire was developed and then designed on Google Forms platforms to collect data from study participants after obtaining a verbal consent form. A total of 422 study participants were included in the survey. Data were entered into Microsoft Excel and then exported to the Statistical Package for the Social Sciences (SPSS) version 25 for analysis.  RESULTS: Face masks and alcohol hand rub/ sanitizer are used by 50. 7 and 24.9% of respondents when required. COVID-19 was thought to have been generated by humans by a substantial percentage of study participants (38.2%). About half (50.7%) and 24.9% of respondents use face masks and alcohol hand rub/sanitizer always when it is required, respectively. A large number of study participants (38.2%) believed that origin of COVID-19 is man-made. Overall, 242 (57.4%) of study participants reported COVID-19 vaccine hesitancy. Fear of vaccine side effects (49.6%) was the most common reason for hesitancy. Doubt about its effectiveness (33.9%), not having enough information about the COVID-19 vaccine, preferring another way of protection, and unreliable of the vaccine (due to its short development period) were also the most frequently mentioned reasons for not receiving the COVID-19 vaccine. CONCLUSIONS: COVID-19 vaccine hesitancy rate was high in Addis Ababa, Ethiopia during the study period. Fear of side effects, doubts about its effectiveness, and not having enough information about the COVID-19 vaccine were major reasons for hesitancy. Continuous awareness creation to the community on the importance of vaccination is warranted by health professionals and healthcare cadres

Characteristics and outcomes of adult Ethiopian patients enrolled in HIV care and treatment: a multi-clinic observational study

Background: We describe trends in characteristics and outcomes among adults initiating HIV care and treatment in Ethiopia from 2006-2011. Methods: We conducted a retrospective longitudinal analysis of HIV-positive adults (≥15 years) enrolling at 56 Ethiopian health facilities from 2006–2011. We investigated trends over time in the proportion enrolling through provider-initiated counseling and testing (PITC), baseline CD4+ cell counts and WHO stage. Additionally, we assessed outcomes (recorded death, loss to follow-up (LTF), transfer, and total attrition (recorded death plus LTF)) before and after ART initiation. Kaplan-Meier techniques estimated cumulative incidence of these outcomes through 36 months after ART initiation. Factors associated with LTF and death after ART initiation were estimated using Hazard Ratios accounting for within-clinic correlation. Results: 93,418 adults enrolled into HIV care; 53,300 (57%) initiated ART. The proportion enrolled through PITC increased from 27.6% (2006–2007) to 44.8% (2010–2011) (p < .0001). Concurrently, median enrollment CD4+ cell count increased from 158 to 208 cells/mm3 (p < .0001), and patients initiating ART with advanced WHO stage decreased from 56.6% (stage III) and 15.0% (IV) in 2006–2007 to 47.6% (stage III) and 8.5% (IV) in 2010–2011. Median CD4+ cell count at ART initiation remained stable over time. 24% of patients were LTF before ART initiation. Among those initiating ART, attrition was 30% after 36 months, with most occurring within the first 6 months. Recorded death after ART initiation was 6.4% and 9.2% at 6 and 36 months, respectively, and decreased over time. Younger age, male gender, never being married, no formal education, low CD4+ cell count, and advanced WHO stage were associated with increased LTF. Recorded death was lower among younger adults, females, married individuals, those with higher CD4+ cell counts and lower WHO stage at ART initiation. Conclusions: Over time, enrollment in HIV care through outpatient PITC increased and patients enrolled into HIV care at earlier disease stages across all HIV testing points. However, median CD4+ cell count at ART initiation remained steady. Pre- and post-ART attrition (particularly in the first 6 months) have remained major challenges in ensuring prompt ART initiation and retention on ART

Khat and alcohol use and risky sex behaviour among in-school and out-of-school youth in Ethiopia

BACKGROUND: Khat (an evergreen plant with amphetamine-like properties) and alcohol are widely consumed among the youth of Ethiopia. However, their relationship to risky sexual behaviour is not well described. This study was conducted to describe the magnitude of risky sexual behaviour (unprotected sex and early initiation of sexual activity) and its association with Khat and alcohol consumption in Ethiopian youths. METHODS: A probabilistic national sample of 20,434 in-school and out-of-school youths aged between 15 and 24 years of age was selected and interviewed regarding their sexual behavior and substance use. RESULTS: Over 20% of out-of-school youth had unprotected sex during the 12-month period prior to interview compared to 1.4% of in-school youth. Daily Khat intake was also associated with unprotected sex: adjusted OR (95% CI) = 2.26 (1.92, 2.67). There was a significant and linear association between alcohol intake and unprotected sex, with those using alcohol daily having a three fold increased odds compared to those not using it: adj. OR (95% CI) = 3.05 (2.38, 3.91). Use of substances other than Khat was not associated with unprotected sex, but was associated with initiation of sexual activity: adj. OR (95% CI) = 2.54 (1.84, 3.51). CONCLUSION: A substantial proportion of out-of-school youth engage in risky sex. The use of Khat and alcohol and other substances is significantly and independently associated with risky sexual behaviour among Ethiopian youths

Impact of land use type on soil seed bank flora in Chilimo Forest, Ethiopia: Implications for natural restoration of vegetation

A very long history of human interference and pressure from population growth has imparted different land use types in the Chilimo forest: shrub land, closed forest, Cupressus lusitanica plantation, Eucalyptus plantation, Juniperus procera dominated stand, Olea europaea subsp. cuspidata dominated stand, open forest, Podocarpus falcatus dominated stand, abandoned arable land, and grassland. A total of 100 plots (each 20 m x 20 m) were used in ten habitat types (10 plots in each) for the collection of data on the soil seed bank and standing vegetation. Soil  samples were collected from within small quadrats (15 cm x 15 cm) from four successive soil layers. A total of 105 plant species were identified from the soil seed bank with total densities ranging between 4991 and 11017 seeds/m2. Of the total recorded species in the soil seed bank, herbaceous species were represented with the largest number (87.6%) whereas the contribution of woody species was low (11.4%). The highest number of species was recorded from the closed canopy stand while the highest density of seeds was found in the arable land. The overall vertical distribution of seeds showed the highest densities occurring in the upper 3 cm soil depth and gradually decreasing with increasing depth, except in the arable land. There was a significant difference among the habitat types in the density of soil seed bank suggesting different types, level and frequency of disturbance on different habitat types. The very low similarity between the soil seed bank and aboveground flora is reflective of both the current and past standing vegetation.Key words/phrases: Afromontane, Forest degradation, Restoration, Soil seed bank, Species diversity

Quality of anticoagulation management with warfarin among outpatients in a tertiary hospital in Addis Ababa, Ethiopia: a retrospective cross-sectional study

Abstract Background Warfarin is the most widely used anticoagulant in the world. The difficulty of managing warfarin contributes to great potential for patient harm, both from excessive anticoagulation and insufficient anticoagulation. This study assessed the International Normalized Ratio (INR) control outcome measures and warfarin dose adjustment practices at cardiology and hematology outpatient clinics at a teaching hospital in Addis Ababa, Ethiopia. Methods The study was based on a cross - sectional study design involving 360 retrospective patients’ chart review among outpatients who received warfarin for its various indications. Results The mean frequency of INR monitoring per patient was 62.9 days (17.2–143.7 days). Patients spent 52.2%, 29.0% and 18.8% of the time in sub-therapeutic, therapeutic and supra-therapeutic ranges, respectively. The daily warfarin dose was increased 50.9% and 36.9% and decreased in 52.8% and 60.9% of the time for occurrences of sub-therapeutic and supra-therapeutic INRs to achieve target ranges of 2.0–3.0 and 2.5–3.5, respectively. Conclusion The quality of anticoagulation management with warfarin among outpatients in Tikur Anbessa Specialized Hospital was sub-optimal. This was reflected by low Time in Therapeutic Range (TTR), longer than recommended INR monitoring frequency, and minimal actions taken to adjust warfarin dose after occurrences of non-therapeutic INRs

Treatment Approaches of Multiple Myeloma

Multiple Myeloma (MM) is the most common malignant neoplasm of plasma cells that accumulate in bone marrow, leading to bone destruction and marrow failure. Clinical investigation of MM requires the evaluation of bone marrow for plasma cell infiltration, and detection and quantification of monoclonal protein in the serum or urine, and evidence for end-organ damage (i.e., hypercalcemia, renal insufficiency, anemia, or bone lesions). The overall goal of treatment of MM is to improve survival. The treatment landscape and clinical outcome of MM have changed in the last two decades, with an improved median survival of 8–10 years. Management of MM involves induction, consolidation, and maintenance therapy. Currently, Autologous stem cell transplant (ASCT) is considered as the standard care of treatment for newly diagnosed fit MM patients. Multiple combinations of proteasome inhibitors (PIs) and immunomodulatory drugs (IMIDs) such as Thalidomide, lenalidomide, and pomalidomide have been under evaluation in ASCT-eligible and ineligible settings, and studies are still ongoing. For patients with ASCT-eligible newly diagnosed MM, induction therapy with triple drugs should contain an IMiD, a PI, and a corticosteroid, usually lenalidomide-bortezomib-dexamethasone. For ASCT-ineligible patients on lenalidomide with dexamethasone (Rd), with addition of bortezomib or daratumumab can be considered

Anti-inflammatory and analgesic activities of solvent fractions of the leaves of Moringa stenopetala Bak. (Moringaceae) in mice models

Abstract Background Many people still experience pain and inflammation regardless of the available drugs for treatments. In addition, the available drugs have many side effects, which necessitated a quest for new drugs from several sources in which medicinal plants are the major one. This study evaluated the analgesic and anti- inflammatory activity of the solvent fractions of Moringa stenopetala in rodent models of pain and inflammation. Methods Successive soxhlet and maceration were used as methods of extractions using solvents of increasing polarity; chloroform, methanol and water. Swiss albino mice models were used in radiant tail flick latency, acetic acid induced writhing and carrageenan induced paw edema to assess the analgesic and anti-inflammatory activities. The test groups received different doses (100 mg/kg, 200 mg/kg and 400 mg/kg) of the three fractions (chloroform, methanol and aqueous). The positive control groups received morphine (20 mg/kg) or aspirin (100 mg/kg or 150 mg/kg) based on the respective models. The negative control groups received the 10 ml/kg of vehicles (distilled water or 2% Tween 80). Results In all models, the chloroform fraction had protections only at a dose of 400 mg/kg. However, the methanol and aqueous fraction at all doses have shown significant central and peripheral analgesic activities with a comparable result to the standards. The aqueous and methanol fractions significantly reduced carrageenan induced inflammation in a dose dependent manner, in which the highest reduction of inflammation was observed in aqueous fraction at 400 mg/kg. Conclusion This study provided evidence on the traditionally claimed uses of the plant in pain and inflammatory diseases, and Moringa stenopetala could be potential source for development of new analgesic and anti-inflammatory drugs

Additional file 1. Factors associated with SSIs occurrence among surgical patients in TASH (N = 131). It is additional material which describes bivariate logistic regression model showing seven variables were associated with the occurrence of SSIs at p < 0.25. Alcohol (p = 0.000), cigarette smoking (p = 0.05), preoperative blood transfusion (p = 0.05), contaminated (p = 0.17) and clean wound (p = 0.12), previous surgery (p = 0.01), and duration of surgery (p = 0.20) were candidate variables for multivariate analysis. The remaining factors were not associated with SSIs development in studied participants

Overall HIV-1 prevalence in pregnant women over-estimates HIV-1 in the predominantly rural population of Afar Region

The appropriateness of sentinel sero-surveillance based upon ante-natal clinic (ANC) attendees to estimate HIV-1 prevalence in the general population has been questioned. In Ethiopia, where the population is heterogeneous and where economic and practical barriers to ANC attendance exist, problems of extrapolation may be exacerbated. We planned an unlinked anonymous sero-survey which included data on basic population characteristics to investigate whether sero-surveillance data from ANCs in Afar Region might be taken to represent the situation among the general population of the Region. 371 pregnant women attending Dubti Hospital and Assayta Health Centre were tested for HIV-1 (using a single ELISA test) and active syphilis (RPR test). Socio-demographic characteristics were collected for each woman. Of the women tested, 278 (75%) were 28 years of age or younger. Two hundred eighty (76%) were urban residents and 237 (64%) described themselves as being of Amhara ethnicity. Overall, 73 (19.7%) were HIV-1 positive, but prevalence was three times higher among the 237 women of Amhara ethnicity compared to the 112 of Afar ethnicity (24.9% vs 8.0%, p < 0.001), and almost three times higher for urban compared to rural residents (23.2% vs 8.8%, p < 0.001). Positive RPR results were strongly associated with HIV-1 infection (OR 3.37, 95% CI 1.47-7.71). According to the Demographic and Health Survey (DHS) 2000, only 4.5% of the population of Afar Region is of Amhara ethnicity, and 7.8% urban residents. We have demonstrated that basing ANC sero-surveillance in urban areas of Afar Region over-samples urban residents of Amhara ethnicity and yields a major over-estimation of overall HIV-1 prevalence for the Region. Reliable estimation of HIV-1 prevalence in Afar Region will require more flexible strategies that permit sampling of rural Afar resident
