Abstract
Background The lack of sophisticated diagnosing equipment for polymerase chain reaction (PCR) during the incidence of variant types of COVID-19 underestimates the morbidity and mortality patterns of this pandemic. Thus, this study aimed to estimate seropositive and confirmatory predictors for COVID-19 suspected and tested cases through polymerase chain reaction (RT-PCR) in two diagnosing. Methods A facility-based descriptive cross-sectional study was employed among COVID-19 suspected cases from January 2, 2022, to June 9, 2022. The data were collected both using a structured interviewees and nasopharyngeal (NP) swabs. The nasal swab (NS) was analyzed in the laboratory for RNA detection of the virus using PCR. The collected data were entered into Epi Data version 4.2 and then exported to STATA (SE) version R-14 software for further analysis. multivariable logistic regression was used to assess the associated risk. Results A total of 285 suspected cases have participated in this study. The overall mean (±SD) age of the participants was 37.5 (±18.5) years. The majority, 174 (61.1%) of the tested groups were symptomatic when diagnosed. The positivity of RT-PCR for suspected and COVID-19 diagnosed cases were confirmed in 62/285 (21.75%). In multivariable analysis, they were aged 26-50 years (adjusted odds ratio [AOR] = 4.2, 95% confidence interval [CI] = 1.5-10.75), had comorbidity (AOR = 5.8; 95% CI = 2.1-12.2), and cigarette smokers (AOR = 13.5; 95% CI = 5.3-36.6) were significantly associated with developing COVID-19 infection. Conclusion More than two in every nine suspected cases were positive RT-PCR tests, and the infectivity of COVID-19 was significantly associated with age 25-50 years, comorbidities, and cigarette smoking. The deployment of high-quality diagnostic kits like RT-PCR is crucial for the early detection and risk stratification of suspected cases.

Abstract
Severe acute malnutrition (SAM) affects up to 50 % of children with HIV, especially those who reside in resource-constrained healthcare setting like Ethiopia. During subsequent follow-up of children factors related to incidence of SAM after antiretroviral therapy (ART) is set on, however, there is no prior evidence. An institution-based retrospective cohort study was employed among 721 HIV-positive children from 1 January to 30 December 2021. Data were entered using Epi-Data version 3.1 and exported to STATA version 14 for analysis. Bi-variable and multivariable Cox-proportional hazard models were employed at 95 % confidence intervals to identify significant predictors for SAM. According to this result, the overall mean (±sd) age of the participants was found to be 9⋅83 (±3⋅3) years. At the end of the follow-up period, 103 (14⋅29 %) children developed SAM with a median time of 30⋅3 (13⋅4) months after ART initiation. The overall incidence density of SAM was found to be 5⋅64 per 100 child (95 % CI 4⋅68, 6⋅94). Children with CD4 counts below the threshold [AHR 2⋅6 (95 % CI 1⋅2, 2⋅9, P = 0⋅01)], disclosed HIV status [AHR 1⋅9 (95 % CI 1⋅4, 3⋅39, P = 0⋅03)] and Hgb level ≤10 mg/dl [AHR 1⋅8 (95 % CI 1⋅2, 2⋅9, P = 0⋅03)] were significant predictors for SAM. Significant predictors of acute malnutrition were having a CD4 count below the threshold, children who had previously reported their HIV status, and having haemoglobin <10 mg/dl. To ensure better health outcomes, healthcare practitioners should improve earlier nutritional screening and consistent counselling at each session of care.

Abstract
BACKGROUND Due to their age category and the immune-suppressing effects of HIV, children were more vulnerable to experience endogenous reactivation of latent bacilli in the lung and increased risk of active tuberculosis incidence. The aim of this study is to assess the survival pattern, risk factors, and estimated time to develop TB after children started ART at selected health facilities of North Wollo, Ethiopia, from November 1, to September 30, 2021. METHODS Facility-based retrospective cohort study was employed from November 1 to September 30, 2021. Cox proportional hazard regression model was used to assess factors associated with incidence of tuberculosis. AHR with 95% CI was used to declare statistical significance for tuberculosis incidence. RESULTS During follow-up, 54 (10.9%) new cases of tuberculosis was reported. At the end of follow-up period, overall cumulative survival probability was determined as 43.8% (95%CI: 28.2-54.3). WHO clinical stage III&IV (AHR: 2.4 (95% CI: 1.4, 4.7), Hgb≤10 gm/dl (AHR = 2.2: (95%CI: 1.12-5.8), missed isoniazid preventive therapy (AHR = 2.5 (95%CI: 1.56-10.3) and Viral Load (≥400 cell/ml) (AHR = 2.02 (95%CI: 2.03-6.8) were significant risk factors for tuberculosis incidence. CONCLUSION Nearly ten % of HIV-positive children experienced new cases of tuberculosis with median time of 25(IQR = ±12) months. It would be better to give special attention to children who missed isoniazid preventive therapy with WHO stages III&IV Viral load (≥400 cells/ml), and Hgb≤10 gm/dl to prevent tuberculosis incidence and prolonged quality of life.

Abstract
The objective of this study was to determine the effects of bioslurry (BS) and chemical fertilizer (CF), as a sole BS and CF and their mixed application, on the agronomic performances of maize (Zea mays var. BH- 546). Field experiment was conducted at Hawassa University Research Farm, in the Sidama Region in Ethiopia. The experiment consisted of six treatments, arranged in a randomized complete block design with three replications. Relevant agronomic characteristics were recorded for each plot, from planting to harvest. Results show yield and yield characteristics of maize increased by both sole and combined application of fertilizers compared to no fertilizer application. The combined BS and CF application at the dose of 25% BS +75% CF gave the highest plant height (251.3 cm), grain yield (7.09 t ha-1), biomass yield (24.4 t ha-1) and stover yield (11.5 t ha-1). The agronomic performances generally increased with increasing proportion of chemical fertilizer in the combined application until the proportion of bio-slurry reaches 75%. Moreover, the combined application generally tended to increase the agronomic performance better than the sole application of both BS and CF. In addition to improving the agronomic performances; both sole BS and its combination with CF reduce the cost of chemical fertilizers. In conclusion, the combined BS and CF application at the dose of 25% BS +75% CF appears an optimal combination and rate for the production of maize in the study area. Yet, as this finding is only one season, further studies determining the optimum dose of sole BS, sole CF, and combined CF and BS for improved maize agronomic performance is commendable in future research.

Abstract
Introduction Iodine is one of the crucial micronutrients required for the normal growth of humans from the fetal stage to adulthood through the synthesis of thyroxin (t3) and triiodothyronine (t4) hormones in the thyroid gland for regulation of metabolism, protein synthesis, and brain development. This study aimed to assess iodine status, the impact of knowledge and practice for adequate iodized salt utilization in household levels in North West Ethiopia. Method A population-based cross-sectional study was carried out using multistage sampling among 1398 residents from 28 December 2021 to 30 January 2022. A systematic random sampling technique was used to select the study participants. The collected data were entered into Epi-Data version 3.1 and then exported to STATA/R version 14 for further analysis. An adjusted odds ratio with 95% CI was used to declare statistical significance at p < 0.05. Result The overall mean (±SD) age of participants was 34.9 (±12.8) years. About 678 (48.5%) had 15-80 ppm, 23 (1.6%) had >80 ppm, 533 (38.13%) had 1.1 ppm to 14.9 ppm, and 147 (10.5) had no iodine in salt (0 ppm) after assessed by Rapid Test Kit. Only 48.5% of the sampled household had used adequate iodized salt with ≥15 ppm. The overall burden of goiter was estimated at 11.4/1000 population. Adequate iodized salt utilization was significantly associated with having formal education (adjusted odds ratio = 1.89: 95% confidence interval: 1.4, 2.6, p = 0.001), monthly income ≥5000 ETB/month (adjusted odds ratio = 1.99: 95% confidence interval: 1.5, 2.9, p = 0.001), and good knowledge score (adjusted odds ratio = 1.6: 95% confidence interval: 1.12, 2.6, p = 0.03) were predictors for proper iodized salt utilization. Conclusion Coverage of adequately iodized salt was low and respondents' formal education, monthly income ≥5000 Ethiopian Birr/month, and good knowledge score were all significantly associated with proper iodized salt utilization. While the prevalence of goiter was not significantly identified as a public health problem as compared in the regions, however, in light of previous iodine deficiency in this region of Ethiopia, the salt iodization program should be done continually.

Abstract
Objectives This study aimed to assess malaria seroprevalence among acute febrile illness cases who come for health care seeking in the high malaria-endemic setting of North West Ethiopia. Methods Institutional-based descriptive serosurvey of malaria infections was employed among 18,386 febrile patients from September 2020 to August 2021. Data were entered using Epi Data version 4.2 and exported to STATA (SE) R-14 version statistical software for further analysis. Bi-variable and multivariable regression analyses were conducted to identify malaria infection. Finally, variables with P-value less than 0.05 were considered significant predictors for malaria infection. Results The mean (±standard deviation) age of participants was 48.6 (±18.4) years. The overall seroprevalence of malaria infection was estimated as 27.8% (95% confidence interval = 27.2; 28.6, standard error = 0.003). Malaria infection was significantly associated with participants being female (adjusted odds ratio = 2.9; 95% confidence interval = 1.8; 3.7, P = 0.01), age 5-29 years (adjusted odds ratio = 2.2; 95% confidence interval = 1.7; 2.8, P = 0.02), rural (adjusted odds ratio = 3.9; 95% confidence interval = 1.9; 4.4, P = 0.001), and Hgb ⩽11 mg/dL (adjusted odds ratio = 3.4; 95% confidence interval = 1.9; 5.86, P = 0.01). Conclusion Nearly every three to ten acute febrile cases were positive for confirmed malaria infection. The risk of malaria infection was significantly associated with respondents being female, aged 5-29 years, rural, and levels of hemoglobin were significantly associated with malaria infection.

Abstract
Background Severe acute malnutrition (SAM) is defined as a weight-for-height < -3z scores of the median WHO growth standards, or visible severe wasting or the presence of nutritional edema. SAM related mortality rates in under-five children are well documented in Ethiopia but data on their predictors are limited. We aimed to document factors associated with SAM related mortality to inform better inpatient management. Methods A facility-based retrospective cohort study was conducted among children admitted due to SAM at Pawe General Hospital, Northwest Ethiopia, from the 1st of January 2015 to the 31st of December 2019. Data from the records of SAM children were extracted using a standardized checklist. Epi-Data version 3.2 was used for data entry, and Stata version 14 was used for analysis. Bi-variable and multivariable Cox regression analyses were conducted to identify predictors of mortality. Variables with P<0.05 were considered significant predictors of mortality. Results Five-hundred sixty-eight SAM cases were identified of mean age was 27.4 (SD± 16.5) months. The crude death rate was 91/568 (16.02%) and the mean time to death was determined as 13 (±8) days. Independent risk factors for death were: (i) vomiting AHR = 5.1 (1.35–21.1, p = 0.026), (ii) diarrhea AHR = 2.79 (1.46–5.4, p = 0.002), (iii) needing nasogastric therapy AHR = 3.22 (1.65–6.26, p = 0.001), (iv) anemia AHR = 1.89 (1.15–3.2, p = 0.012), and (v) being readmitted with SAM AHR = 1.7 (1.12–2.8, p = 0.037). Conclusion SAM mortality was high in under-five children in our setting. The identified risk factors should inform treatment and prevention strategies. Improved community health education should focus on healthy nutrition and seeking early treatment. Inpatient mortality may be reduced by stricter adherence to treatment guidelines and recognizing early the key risk factors for death.

Abstract
Despite efforts to decrease the burden, vaccine hesitancy is increasing worldwide and deterring efforts to control the spread of COVID-19 after the approval of SARS-CoV-2 vaccines. This study aims to assess levels of COVID-19 vaccine acceptance and predictors of hesitancy for pregnant women attending antenatal care in Ethiopia.
Methods: Facility-based cross-sectional study was employed among 336 pregnant women from April 7 to June 10, 2021. The systematic random sampling technique was used to select pregnant from three health centers. Epi-Data version 3.2 and STATA/14 software were used for both data entry and analysis, respectively. A Logistic regression model was used to identify predictors of COVID-19 vaccine hesitance. Adjusted odds ratio (AOR) with a 95% confidence interval was used to estimate the strength of association at P<0.05.
Result: This study included 336 pregnant mothers who were booked ANC in three health centers. The overall levels of COVID-19 vaccine acceptance among pregnant mothers were 79.17 %(95%CI: 74.5 --83.2). Whereas, having poor attitude towards COVID-19 vaccines (AOR=9.4; 95%CI: 3.7--21.1, P<0.001), monthly income ≤118.5 US dollar (AOR =6.3; 95%CI: 2.9--12.2, P<0.002), Mother who are illiterate and started ANC (AOR=9.5; 95%CI: 4.6--22.6, P<0.001), Being unplanned pregnant (AOR =7.5; 95%CI: 3.6-11.2, P<0.002), first time ANC initiated (AOR =4.2; 95%CI: 2.9--15.1, P<0.001), and pregnant didn’t used social media (AOR= 6.0: 95%CI: 2.5--14.6, P< 0.02) were significantly associated with COVID-19 Vaccine hesitance.
Conclusion: The acceptability of the COVID-19 vaccine among pregnant mothers was insufficient compared with previous research. Health care workers should provide health education during ANC visits to change their negative attitude and reassurance for the safety and effectiveness of the COVID-19 vaccine.

Abstract
Objectives: The spread of severe acute respiratory syndrome coronavirus 2 in Ethiopia is below par understood and to date has been poorly characterized by a lower number of confirmed cases and deaths to other regions of the sub-Sahara African including Ethiopia. Timely and effective predictors for inpatient mortality rate were crucial for improving the management of hospitalized cases. This study aimed to assessed predictors for inpatient mortality of COVID-19 hospitalized adult patients in two diagnosed and treatment centers, North West Ethiopia. Methods: A facility-based retrospective cohort study was conducted among COVID-19 adult admitted cases in two treatment centers, Northwest Ethiopia, from 1 October 2020 to 30 December 2020. Data from the records of children were extracted using a standardized checklist. Epi-Data version 3.2 was used for data entry, and Stata version 14 was used for analysis. Bi-variable and multivariable Cox regression analyses were conducted to identify predictors of mortality. Finally, variables with P < 0.05 were a significant predictor of inpatient mortality. Result: The mean (±standard deviation) age of participant cases was 48.6 (±18.8) years. The median (±interquartile range) time for death reported after was 13 (±6) days. The overall incidence rate inpatient mortality rate was determined as 1.8 (95% confidence interval: 1.72, 2.15) per100 person per days of observation. Cases at baseline age ⩾ 61 years (adjusted hazard ratio = 1.56; 95% confidence interval: 1.3, 2.4), being male gender (adjusted hazard ratio = 1.9; 95% CI: 2.1, 8.6), admission with comorbidity (adjusted hazard ratio: 4.4, 95% confidence interval: 2.3, 8.4), and decreased neutrophil count ⩽ 65 103/uL at (P < 0.03) were independent predictors for inpatient mortality. Conclusion: In general, 72.4% of COVID-19 inpatient deaths were occurred within 2 weeks after admission. The mortality risk factors for severe patients identified in this study using a multivariate Cox regression model included elderly age (⩾60 years), being male, baseline comorbidity, and neutrophil count ⩽65 103/uL were associated with inpatient mortality.

Abstract
Objective: The spread of Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2) in Ethiopia is below par understood and to date has been poorly characterized by a lower number of confirmed cases and deaths as compared with other regions of the Sub-Saharan African (SSA) countries. We aimed to investigate the seroprevalence of SARS-CoV-2 specific IgG antibodies, using the Abbott anti-nucleocapsid IgG chemiluminescent microparticle immunoassay, in two COVID-19 diagnosed and treatment centers of quarantined population during the first wave of the COVID-19 pandemic (since 30 April–30 May 2020). Methods: We analyzed data of 446 quarantined individuals during the first wave of COVID-19 pandemic. The data were collected using both interviewed and blood sample collection. Participants asked about demographic characteristics, COVID-19 infection symptoms, and its practice of preventive measures. Seroprevalence was determined using the severe acute respiratory syndrome coronavirus 2 IgG test. Results: The mean (± standard deviation) age of the respondent was 37.5 (±18.5) years. The estimated SARS-CoV-2 infection seroprevalence was found 4.7% (95% confidence interval: 3.1–6.2) with no significant difference on age and gender of participants. Severe acute respiratory syndrome coronavirus 2 antibody seroprevalence was significantly associated with individuals who have been worked by moving from home to work area (adjusted odds ratio = 7.8, 95% confidence interval: 4.2–14.3, p < 0.019), not wearing masks (adjusted odds ratio = 2.4, 95% confidence interval: 1.9–3.8, p < 0.02), and baseline comorbidity (adjusted odds ratio = 6.3, 95% confidence interval: 2.3–17.1, p < 0.01) as compared to their counter groups, respectively. Conclusion: Our study concluded that lower coronavirus disease 2019 seroprevalence, yet the large population in the community to be infected and insignificant proportion of seroprevalence, was observed between age and sex of respondents. Protective measures like contact tracing, face covering, and social distancing are therefore vital to demote the risk of community—strengthening factors should be continued as effect modification of anticipation for severe course of coronavirus disease 2019.

Abstract
Single, binary and ternary nanomaterials were synthesized by precipitation, solvothermal, simple solution and impregnation methods to serve as photocatalysts. The crystal structure, morphology, band gap energy, functional groups and optical properties of these materials were characterized by XRD, SEM-EDX, UV-Vis, FTIR, and PL instrumental techniques, respectively. Photocatalaytic degradation performances of all the as-synthesized photocatalysts were investigated under visible light irradiation using MO as a model organic pollutant. The photocatalytic degradation performances of all the photocatalysts were evaluated on aqueous solution of the model pollutant dye as well as on a real sewage sample solution collected from Bahir Dar Textile Share Company. Results suggested that the optimized ternary nanocomposite photocatalyst exhibited a relatively higher efficiency towards the photodegradation of both the methyl orange (MO) dye solution (90%) and the real sewage sample solution (71.2%). The effect of operational parameters such as pH (4), initial dye concentration (10 mg/L) and photocatalyst load (0.2 g/L) in MO dye degradation were investigated by using the ternary CdS/UiO-66/Ag3PO4 (R4) nanocomposite.

Abstract
A fast agglutination screening test (FAST) for the detection of Leishmania antibodies in human serum samples was evaluated under harsh field conditions in northern Ethiopia. Test performance was compared with a standard serological test, namely the direct agglutination test (DAT), and with parasitology. In total, 103 suspected cases were recruited for the study. Based on parasitological examination, 49 patients were confirmed of having visceral leishmaniasis (VL) and the other 54 suspected cases were parasitologically negative. Field evaluation of FAST was possible in blood samples of 89 patients. FAST had 4 false negative results and 13 false positive results. DAT had 2 false negative results and 20 false positive results. A good degree of agreement (86.9%) was observed between FAST and DAT (kappa value 0.73). In this field-based evalauation, the sensitivity and specificity of FAST were found to be 91.1% (95% CI 77.9-97.1) and 70.5% (95% CI 54.6-82.8), respectively, compared with 95.3% (95% CI 82.9-99.2) and 62.3% (95% CI 47.9-74.9) for DAT. FAST had a high predictive value of a negative test, demonstrating that FAST could be utilised to exclude rapidly non-VL patients from a large population of suspects with fever and splenomegaly in endemic areas.

Abstract
Helicobacter pylori infection was detected in 93% of 174 patients with a peptic ulcer compared with 63% of 116 patients with normal findings (chi 2 = 37.3; P < 0.001) in a cohort of 834 consecutive patients examined by gastroscopy in Yirga Alem Hospital in south Ethiopia. Fourteen patients were given 14 days' treatment with metronidazole 500 mg t.i.d., doxycycline 100 mg b.i.d. and bismuth subnitrate mixture 150 mg q.i.d. Of 10 patients who returned for follow-up, only 2 patients were free from H. pylori and cured. Nineteen strains of H. pylori from 19 consecutive patients in the same hospital were tested for resistance in vitro against metronidazole, doxycycline and ampicillin. All but 1 were highly resistant to metronidazole; 2 were fully and 14 intermediate resistant against doxycycline. All strains were fully sensitive in vitro to ampicillin. Thus, peptic ulcer was strongly associated with H. pylori in south Ethiopia, but eradication of the infection was hampered by antibiotic resistance.

Abstract
The levels of human immunodeficiency virus type 1 p24 antibodies and p24 antigen among 256 Ethiopians and Africans and 86 Swedes were compared. The elevated levels of total anti-p24 immunoglobulin G (IgG) and anti-p24 IgG4 among the Ethiopian and African patients suggest influences from T-helper-cell type 2-like responses.

Abstract
We have tested the sequence UUC CAG UCA GAC CU, at position 9016--9029 within the HIV-1(SF2) nef open reading frame, for accessibility to antisense and hammerhead ribozyme attack. The accessibility was first studied using a phosphorothioate-modified 14-nt DNA oligo (complementary to the nef9016--9029 site). A dose-dependent repression of HIV-1(SF2) growth was observed in human peripheral blood mononuclear cells after exogenous administration of the oligo to the cell culture medium. A hammerhead ribozyme with a 6+7-nt antisense specificity for the nef9016--9029 site (hhRz.nef9016--9029) was constructed and transfected into the human T-cell line HUT78. Again, a dose-dependent repression of virus growth was observed when different individual clones expressing hhRz.nef9016--9029 were infected with HIV-1(SF2). A complete abrogation of virus production was observed after infection with a low (0.5 TCID50) HIV-1 titer. Increasing doses (2.5 and 12.5 TCID50) of HIV-1 virus yielded a low production (10(3)-fold reduced) of virus particles in most cases; but a complete, or close to complete, abrogation was observed even in individual cultures infected with the highest dose. Presence of proviral pol and gag sequences in hhRz.nef9016--9029-expressing HUT78 clones was assayed, using PCR. Interestingly, since no pol and gag PCR products could be detected, the results strongly indicated that the hammerhead ribozyme was already acting on the infecting HIV RNA before its reverse transcription and integration as proviral DNA. In summary, the results obtained in this study support the nef9016--9029 site as a strong new candidate for ribozymal gene therapy against HIV-1 infection.

Abstract
Sera from 500 (496 male and 4 female) consecutive patients with sexually transmitted diseases (STD) were examined for the presence of HIV1 antibodies. The serological tests were done using the ELISA (Wellcozyme) and confirmed by the western blot (Biorad). Sixty (12%) of the 500 patients were HIV-1 antibody positive. Seropositivity varied with the type of STD. A positivity rate of 16% seen with genital ulcer disease is significantly higher than the 7% prevalence rate seen in STD patients with urethral discharge. Infection with more than one kind of STD increases seropositivity significantly. Of the potential risk factors identified during the interview it seems that only shaving at barbers' shop is positively associated with seroprevalence. This study suggests that the presence of STDs is associated with an increased HIV-1 seroprevalence. Therefore, any effort to reduce HIV-1 infection should aim at the control of STDs.
