Knowledge and attitude toward human papillomavirus vaccination and associated factors among adolescent school girls in Ambo town, Ethiopia, 2021: A multicenter cross-sectional study.

Background and Aims: The human papillomavirus (HPV) vaccination has shown considerable promise in lowering the incidence of cervical cancer. However, there are few studies done on knowledge and attitude toward the HPV vaccine, especially in the local setting. Therefore, this study aimed to assess knowledge and attitudes regarding HPV vaccination and related factors among adolescent girls in Ambo town, Ethiopia, in 2021. Methods: A cross-sectional study was conducted from May 1 to May 30, 2021, at selected schools in Ambo town among 422 adolescent girls. A structured self-administered questionnaire was used to collect the data. The collected data were coded, and entered into Epi-Info 7.2.2.6 and exported to STATA 16 for analysis. Descriptive statistics were used to compute summary statistics and proportions. Bivariate and multivariate logistic regression analyses were carried out. The adjusted odds ratio (AOR) along with a 95% confidence interval (CI) was computed to ascertain the association. Results: Current study revealed that 24.9% (95% CI: 20.8-29.0) and 55.6% (95% CI: 50.5-60.4) of respondents had good knowledge and favorable attitude, respectively. The factors like being secondary school students [AOR = 2.01, 95% CI; (1.24, 3.27)], having health workers as a source of information [AOR = 2.13, 95% CI; (1.30, 3.47)], and respondents who have heard about the HPV vaccine at school [AOR = 1.66, 95% CI; (1.02, 2.71)] were significantly associated with respondent's knowledge of HPV vaccine. Moreover, the perceived severity of the diseases [AOR = 2.89, 95% CI; (1.61, 5.21)], and the perceived benefit of the vaccine [AOR = 4.26, 95% CI; (2.43, 7.48)] were factors significantly associated with an attitude of the respondents about the HPV vaccine. Conclusion: There was low knowledge and unfavorable attitude toward HPV vaccination among the school adolescents in the study area. Several seemingly major deterrents of knowledge and attitude toward the HPV vaccination were identified. Therefore, all parties involved should collaborate to improve female students' knowledge and attitudes toward Human Papilloma Virus vaccination.

Human papillomavirus vaccination uptake and its associated factors among adolescent school girls in Ambo town, Oromia region, Ethiopia, 2020.

BACKGROUND: The Human Papillomavirus (HPV) vaccine has offered a great promise to reduce the cervical cancer burden; its utilization (uptake) however has been lagging. However, the levels and factors associated with the uptake of the vaccine have not been well investigated, especially in the local context. OBJECTIVE: To assess the uptake of human papillomavirus vaccination and its associated factors among adolescent school girls in ambo town, Oromia, Ethiopia, 2020. METHODS: An institution-based cross-sectional quantitative study design supplemented with the qualitative inquiry was employed to assess Human Papillomavirus vaccination uptake and its associated factors among 422 adolescent school girls in Ambo town, central Ethiopia from December 1-30, 2020. The collected data were coded, entered, and cleaned by using Epi info 7.2.3 and exported to SPSS version 25 for analysis. Descriptive statistics were used to compute summary statistics and proportions. Both bivariate and multivariable logistic regression was employed to identify factors associated with HPV vaccine uptake. Adjusted odds ratio and 95% confidence interval were used for the strength and directions of association. A P-value of < 0.05 was used to declare statistical significance. Qualitative findings have been analyzed with manual thematic analysis. RESULT: The proportion of HPV vaccination uptake among school girls in this study was 44.4%. Hearing about HPV vaccine [AOR = 2.50, 95%CI: (1.045-5.959)], availability of awareness creation [AOR = 2.53, 95%CI: (1.507-4.258)], and favorable attitude [AOR = 2.049, 95%CI: (1.153-3.64)] were the key identified factors associated with vaccination uptake. In addition, poor perception, fear of side effects, and misunderstanding were among the major factors identified by qualitative findings. CONCLUSION: There was low uptake of HPV vaccination among the school Adolescents in the study area. Availability of awareness creation programs, favorable attitude towards HPV vaccine, and hearing about HPV vaccine was significantly associated with the uptake of the HPV vaccination. Therefore, awareness creation and behavior change education are mandatory to scale up the vaccination.

Adherence to Self-Care Practices and Associated Factors Among Outpatient Adult Heart Failure Patients Attending a Cardiac Center in Addis Ababa, Ethiopia in 2020.

INTRODUCTION: Proper self-care in patients with chronic illnesses, such as heart failure is allied with the prevention or early detection of health problems and improved clinical outcomes. Even though self-care among patients with heart failure is commonly poor, a low-sodium diet, regular exercise, and weight monitoring are essential to control heart failure symptoms and exacerbation. Poor adherence to these self-care practices contributes to an increase in hospitalization, morbidity, and mortality. OBJECTIVE: To assess adherence to self-care practices and associated factors among outpatient adult heart failure patients attending cardiac center in Ethiopia, Addis Ababa, 2020. METHODS: Institution-based cross-sectional study design was used to incorporate 396 heart failure patients who attended the cardiac center in Ethiopia, Addis Ababa. The study was conducted from March to April 2020. Study participants were selected by using a systematic sampling technique. Data were collected through face-to-face interviews and from the patients' medical records. Epi-data version 3.1 and SPSS version 26 were used for data entry and analysis, respectively. Binary logistic regression analysis was performed to identify predictors of self-care practice. Those variables with p-value <0.25 in the bivariable regression analysis were entered into the multivariable regression analysis and the result were presented using tables, chart, and mean. RESULTS: Of 396 respondents, 111 (28%) of patients with heart failure had overall good self-care adherence. Comorbidity (AOR: 1.62; 95% CI: 1.07-2.624), level of knowledge (AOR: 3.58; 95% CI: 2.23-5.79) and depression (AOR: 2.45; 95% CI: 1.048-5.726) were factors significantly associated with adherence to self-care practice. CONCLUSION: Comorbidity, inadequate knowledge, and depression were predictors of self-care practice. As a result, nursing intervention programs regarding knowledge on heart failure are recommended for enhancing self-care practices. Self-care strategies shall target patients with depression and comorbidity.

Modern Health Service Utilization and Associated Factors among Adults in Southern Ethiopia.

Background: The Ethiopian government is striving to improve the health status of its population through the expansion and strengthening of primary health care services in both rural and urban settings of the country. The study aimed to measure modern health service utilization and associated factors in Wolaita Sodo town, Ethiopia. Method: A cross-sectional study design was implemented from May to June 2019 in Wolaita Sodo town, Ethiopia. All 786 study participants were selected by multistage systematic random sampling. Data were collected by face-to-face interviews using a pretested structured questionnaire. Data were collected by an open data kit. Stata window version 15.0 was also employed for statistical analysis. Multiple logistic regression was conducted, and a 95% confidence interval was considered for interpretation. Result: Health service utilization was 77.2% with (95% CI of 74.1%, 80.0%). In terms of health facilities in which they visit, first 50.6% were at the public health center and 25.5% of them were at Teaching and Referral Hospital. Respondents with marital status married and widowed have higher odds of utilizing health services compared to single marital status (AOR: 2.96; 95% CI: 1.7-5.2 and 9.0; 95% CI: 1.69-48.0), respectively. Respondents with middle and highest wealth status have higher odds of health service utilization than poor wealth status with AOR (1.75 95% CI 1.03-2.97 and 1.58 95% CI; 1.01, 2.77). Similarly, respondents who had chronic disease and perceived poor health status have higher odds of health service utilization. Conclusion: Modern health services utilization was found to be unsatisfactory. Being married, wealth status being middle and high, having chronic health conditions, and having poor perceived health status were found to have a statistically significant association with health service utilization.

Long-term occurrence of Trypanosoma congolense resistant to diminazene, isometamidium and homidium in cattle at Ghibe, Ethiopia.

Ten trypanosome isolates were collected at random from cattle at Ghibe, Ethiopia, in February 1993 and all shown to be savannah-type Trypanosoma congolense. When inoculated into naïve Boran (Bos indicus) calves, all 10 isolates were resistant to diminazene aceturate (Berenil), isometamidium chloride (Samorin) and homidium chloride (Novidium) at doses of 7.0 mg/kg body weight (b.w.), 0.5 mg/kg b.w. and 1.0 mg/kg b.w., respectively. In order to determine whether this multiple-drug resistance was expressed by individual trypanosomes, clones were derived from two of the isolates and characterised in mice for their sensitivity to the three compounds; by comparison to drug-sensitive populations, the two clones expressed high levels of resistance to all 3 trypanocides. In experiments to characterise the uptake kinetics of [14C]-Samorin, the maximal rates of uptake (Vmax) for 4 Ghibe isolates ranged from 9.2 to 15.0 ng/10(8) trypanosomes/min. In contrast, Vmax for the isometamidium-sensitive clone T. congolense IL 1180 was 86.7 +/- 8.6 ng/10(8) trypanosomes/min. Lastly, molecular karyotypes were determined for eight isolates: seven different chromosome profiles were observed. These data indicate that in February 1993 there was a high prevalence of drug-resistant trypanosome populations with different chromosome profiles in cattle at Ghibe. Since a similar situation existed at the same site in July 1989, this suggests that the drug-resistance phenotype of trypanosomes at Ghibe had not altered over a 4 year period.

The use of ribotyping and antibiotic resistance patterns for identification of host sources of Escherichia coli strains.

AIMS: To compare antibiotic resistance and ribotyping patterns ability to identify triplicate isolates sent from a group of 40 Escherichia coli taken from seven host sources. METHODS AND RESULTS: Of the 120 isolates, 22 isolates were resistant to ampicillin, streptomycin, tetracycline and trimethoprim and 98 isolates were susceptible. Antibiotic patterns identified 33 of the triplicates and three of the six groups had isolates from multiple hosts. Ribotyping divided the isolates into 27 ribotype groups with all triplicates grouped into the same ribotype group with one host per group. CONCLUSIONS: Antibiotic susceptibility pattern placed 98 of the isolates in a single group with 50% of the antibiotic susceptibility pattern groups containing multiple host species. Ribotyping groups were host specific with each host having one to seven ribotype groups. SIGNIFICANCE AND IMPACT OF THE STUDY: Antibiotic susceptibility pattern groups have been used for environmental source identification and faecal pollution tracking, however these groups do not always distinguish between host species. Stability of the markers is a potential concern and this system can only be used if antibiotic resistance levels are high in the isolates studied. All isolates have a ribotype group which was stable and like other molecular methods has advantages over antibiotic susceptibility pattern groups which uses a phenotypic method.

Modulation of mitochondrial electrical potential: a candidate mechanism for drug resistance in African trypanosomes.

Bloodstream forms of four populations of the livestock pathogen Trypanosoma congolense, isolated from different natural infections, have been shown to exhibit a wide range of sensitivities to the trypanocide isometamidium chloride (Samorin(R)). In mice the 50% curative doses (CD50) for Samorin range from 0.007 to 20 mg/kg body weight. Uptake of isometamidium chloride demonstrated Michaelis-Menten-type kinetics in all the populations, with Km values in the range 0.35-0.87 microM, and Vmax varied from 17 to 216 pmol/min per 10(8) cells. The magnitude of Vmax was correlated with sensitivity to the drug. In contrast, no correlation was observed between Km values and drug sensitivity. Pulse-chase experiments indicated two compartments for accumulation of drug. The first consists of freely diffusible drug that is invariant between populations; the other consists of retained isometamidium, which is of variable magnitude between the populations and is correlated with drug sensitivity. Autoradiography and fluorescence microscopy demonstrated initial, rapid accumulation of the drug within the mitochondrion, specifically the kinetoplast. In a drug-sensitive population of T. congolense, agents affecting mitochondrial function were shown to produce dose-dependent inhibition of mitochondrial membrane potential (DeltaPsimito), as measured by the accumulation of the lipophilic cations [3H]methyltriphenylphosphonium iodide or rhodamine 123. The agents also produced parallel inhibition of isometamidium uptake, suggesting an involvement of DeltaPsimito in the accumulation of the drug. When characterized in each of the four populations, the spontaneous DeltaPsimito was shown to be characteristic of each population and was correlated with Vmax for drug uptake and sensitivity to the drug in vitro and in vivo. We therefore conclude that in T. congolense DeltaPsimito is an important determinant of the rate and accumulation of the trypanocide isometamidium chloride. Populations of this trypanosome species vary with respect to DeltaPsimito, which is correlated with sensitivity to isometamidium. We suggest that when exposed to drug, the selection of such populations represents a novel mechanism of drug resistance in protozoan parasites.
