Molecular characterization of Streptococcus agalactiae isolated from pregnant women and newborns at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia.

ABSTRACT: BACKGROUND:Streptococcus agalctiae (Group B Streptococcus, GBS) is a perinatal pathogen and a leading cause of neonatal infections worldwide. Serotype, sequence type, clonality, antibiotic resistance genes and surface protein profiles of GBS are scarce in Ethiopia, a reason that this study was planned to investigate. . METHODS:Sixteen colonizing GBS isolates obtained from recto-vaginal swabs of pregnant women and body surfaces of newborns were further analyzed. Minimum inhibitory concentration (MIC) test, and whole genome sequence (WGS) methods were done for antibiotic susceptibility test, and molecular characterization of the isolates. RESULTS:All the GBS isolates analyzed were belonged to four capsular serotypes: II, 11/16(68.8%), V, 3/16(18.8%), Ia and VI each with 1/16(6.3%) and five sequence type (ST-2, ST-10, ST-14, ST-569 and ST-933). Sequence type-10 was the most predominant ST followed by ST-569. The five STs were grouped into the four clonal complexes (CC - 1, CC-10, CC-19, and CC-23). Different surface proteins and pili families such as ALP1, ALPHA, ALP23, PI-1 / PI-2A1, PI-1 / PI-2B, and Srr1 were detected from WGS data. All isolates were found to be susceptible to the tested antibiotics except for tetracycline in MIC and WGS test methods used. Tetracycline resistant determinant genes such as TETM and TETL / TETM combination were identified. CONCLUSION:Further studies on serotype and molecular epidemiology will provide a comprehensive data of the GBS capsular serotype and clones available in Ethiopia.

Project description:BackgroundRefractive error is one of the commonly encountered problems during pregnancy and being the cause of deleterious effects on health. Despite its impacts, there is no evidence on the magnitude and associated factors of refractive error among pregnant women in Ethiopia. This study aimed to determine the prevalence of refractive error and its associated factors among pregnant women attending antenatal care unit at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia, 2020.MethodsAn institution-based cross-sectional study was employed. An ocular examination was performed using Retinoscope and Snellen's illiterate "E" chart. The required data were collected using an interviewer-administered questionnaire which comprised socio-demographic, clinical and pregnancy-related variables. EpiData 3.02 and STATA 14 were used for data entry and analysis respectively. Both bivariable and multivariable binary logistic regression analyses were executed to identify factors associated with refractive error. Variables with a p-value ≤ 0.05 in the multivariable logistic regression analysis were declared as significantly associated factors with refractive error.ResultsA total of 401 pregnant women with a median age of 27 (IQR = 24-31) years participated in this study. The overall prevalence of refractive error among the study participants was 35.66% (95% CI: 30.95-40.37). Of the total study participants, ninety-two (22.90%) of them were myopic, forty-five (11.22%) were hyperopic and the rest were antimetropic. Increased maternal age (AOR = 1.31; 95% CI: 1.16-1.48)), increased parity (AOR = 3.17, 95% CI: 1.92-5.25), increased gestational age (AOR = 1.15, 95% CI: 1.08-1.22), and regular use of computers/ watching television (AOR = 6.19, 95% CI: 2.46-15.59) were significantly associated with refractive error.ConclusionThe prevalence of refractive error among pregnant women was high where myopia was the most common variety. Advanced maternal age, increased gestational age, increased parity and regular use of computer or watching television were significantly associated with refractive error among pregnant women. Therefore, apart from providing other maternal health services, routine screening and evaluation of pregnant women for refractive error during antenatal care visit is recommended to avoid its negative impacts.

Project description:BackgroundObstetric ultrasound is one of the most important advances in antenatal tests. Despite the importance of knowing the knowledge status of ultrasound and the category of attitude, there is no similar study done in Ethiopia. Thus, this study aimed to assess knowledge and attitude and associated factors toward ultrasound examination at the University of Gondar comprehensive specialized hospital, Northwest Ethiopia.MethodsInstitutional-based cross-sectional study was conducted at the University of Gondar comprehensive specialized hospital, Northwest Ethiopia from May 15, 2022, to Jun 30, 2022. Data was collected and transferred from the Open data Kit server and analyzed using STATA version 14. The strength of the association, presented using an adjusted odds ratio with a 95% confidence interval and p-value ≤0.05, is considered to declare statistically significant variables.ResultsA total of 422 pregnant women participated, with a response rate of 100%. Of the total pregnant women, only 39% of them are knowledgeable about obstetric ultrasound whereas 52% of them have a favorable attitude. Being a housewife, government employee, and private employee (AOR = 17, 95% CI = 2.12, 151), (AOR = 10, 95% CI = 1.2, 85) and (AOR = (13, 95% CI = 1.5, 115), respectively were associated positively with knowledge about ultrasound. However, residing in a rural (AOR = 0.07; 95%CI = 0.02, 0.21), never been pregnant before (AOR = 0.59 95% CI = 0.38, 0.94), and having information (AOR = 1.7, 95% CI = 1, 2.9) were negatively associated with knowledge about ultrasound. Whereas, attaining primary education (AOR = 2.61; 95%CI = 1.1, 6.4) was positively associated with favorable attitudes while living in rural areas was negatively associated with a favorable attitude (AOR = 0.42; 95%CI = 0.18, 0.97).ConclusionIn this study, knowledge and attitude about ultrasound among pregnant women in Gondar City are low. Residence, occupation, being pregnant before, and having information were significantly associated factors of knowledge. While residence and educational status of the respondents were significant factors of attitude. Therefore, health information about obstetric ultrasound shall be given to women who live in rural areas, women who are students, merchants and farmers, illiterate, and primigravida.

Project description:Introduction. Pain is unpleasant sensory and emotional experience associated with actual and potential tissue damage. Inadequate pain management has been shown to affect patient outcomes by potentially increasing hospital stay and delaying recovery; thus, the management of pain has major implications for nursing. The study was aimed to identify gaps in knowledge and attitude of nurse's level of pain management. Objective:This study aimed to assess knowledge and attitude towards pain management among nurses working at University of Gondar comprehensive specialized referral hospital, Northwest Ethiopia, 2019. Methods:Institution-based cross-sectional study was carried out during May 20-30, 2019. A stratified random sampling technique was used to select 422 nurses. Hospital departments were classified into 5 main strata having nearly the same working conditions: (1) Internal Medicine, (2) Pediatrics, (3) Surgical, (4) Outpatient Clinics, and (5) Emergency and Intensive Care Departments. The proportional allocation was taken from each stratum, and then a simple random technique was applied. Descriptive statistics like frequency, mean, median, standard deviation, and percentage were used to describe the distribution of data. Independent samples t-test was used in comparing the gender knowledge and attitude mean score of the nurses towards pain management. One-way ANOVA was also used in determining the differences between knowledge and attitude towards pain management with sociodemographic characteristics at the p=0.05 level of significance. Result:A total of 411 study participants were involved in this study. More than half of the nurses, 225 (58.1%), were males; 308 (79.5%) of them were in the age category of 19-29 years. The magnitude of good knowledge towards pain management among nurses was 66.9% with a mean score of 7.14 (1.74 SD). The magnitude of favorable attitude towards pain management among nurses was 51.7% with a mean score of 49.33 (7.13 SD). Conclusion and Recommendation. This study revealed that nurses working at University of Gondar hospital had good knowledge and a lower level of attitude towards pain management than those reported in previous studies. Thus, the situation demands various educational and quality improvement initiatives that could enhance the nurse's knowledge and attitude in the area of pain management.

Project description:BackgroundNeonatal meningitis continues to be a devastating infection with high mortality and morbidity worldwide. The prevalence of neonatal meningitis varies across countries. However, there is a paucity of studies on neonatal meningitis in most low-resource settings. Therefore, this study aimed to determine the magnitude, clinical presentations, and associated risk factors of meningitis among newborns with neonatal sepsis.MethodAn institution-based, cross-sectional study was conducted among newborns with neonatal sepsis from May 1, 2021, to Oct 30, 2021. Neonates with neonatal sepsis admitted to the University of Gondar Comprehensive Specialized Hospital (UOGCSH) during the study period were included in the study. Single population proportion formula was used to calculate the sample size and a systematic random sampling technique was used to select the study participants. Two trained pediatric residents collected the data by using a pretested, structured questionnaire. The data was entered into Epi-info version 7.0 and exported to SPSS version 24.0 for analysis. Binary logistic regression was used to identify the associated factors. P-value<0.05 was considered statistically significant.ResultA total of 171 participants were enrolled in this study. The mean postnatal age was 10.74±8.0 days. The male to female ratio was l.3:1. The prevalence of neonatal meningitis among suspected sepsis was 19.3%; 95% CI [13.5%-25.1%]. The prevalence of meningitis was 22.8% in Early-Onset Neonatal Sepsis and 16.8% in Late-onset Neonatal Sepsis. Neurologic symptoms (seizure & altered mentation) were seen in 25% of the patients with meningitis. Two risk factors, Prolonged labor (adjusted odds ratio [AOR]: 4.98; 95% CI: 1.99-12.48) and Prolonged Rupture of Membrane (AOR: 5:38; 95% CI: 1.92-14.42) were significantly associated with neonatal meningitis.ConclusionThe prevalence of neonatal meningitis was higher in early-onset neonatal sepsis than in late-onset neonatal sepsis. Obstetric factors were associated with neonatal meningitis. We recommend that routine CSF analysis should be practiced in all neonates with neonatal sepsis regardless of their postnatal age and clinical features. Early detection and treatment of obstetric factors may have the potential to reduce neonatal meningitis.
