Background: The increased occurrence of malaria among Africa's displaced communities poses a new humanitarian problem. Understanding malaria epidemiology among the displaced population in African refugee camps is a vital step for implementing effective malaria control and elimination measures. As a result, this study aimed to generate comprehensive and conclusive data from diverse investigations undertaken in Africa., Methods: This review adhered to PRISMA standards, involving searches across electronic data bases such as Google Scholar, PubMed, Web of Science, Scopus, and Science Direct. In addition, grey literature was retrieved from several professional associations. The quality of selected studies was evaluated using the Newcastle-Ottawa Quality Assessment Scale. Data extraction was executed using Microsoft Excel, and the meta-analysis was performed with STATA 14 software. A random-effects model was used to estimate the pooled prevalence and associated factors of malaria. Meta-regression and subgroup analysis were used to identify heterogeneity, while funnel plots and Egger's statistical tests assessed the publication bias. Furthermore, a sensitivity analysis was performed., Results: The overall random-effects pooled prevalence of malaria infection (comprising symptomatic and asymptomatic cases) across all included studies was 35.93% (95% CI 24.71-47.15). This study showed a high level of heterogeneity between studies (I2 = 97.1; P < 0.001). Of the identified Plasmodium species, Plasmodium falciparum constituted 99.3%. The frost plot indicated that the overall prevalence of P. falciparum was 34.94% (95% CI 24.34-45.53). Subgroup analysis revealed significant variation (P < 0.001) in malaria prevalence between asymptomatic and symptomatic cases, with a prevalence of 4.39% (95% CI 2.57-6.21) and 45.10% (95% CI 27.28-62.92), respectively. Lack of insecticide-treated mosquito net utilization (AOR 2.43; 95% CI 1.01-5.88) and living near mosquito breeding sites (AOR 2.76, 95% CI 1.56-4.87) were risk factors of malaria., Conclusion: This study determined that the pooled prevalence of malaria among displaced individuals in refugee camps was high and exhibited variations across different population groups. This signifying there is still a need to improve and recheck existing malaria prevention and control strategies to establish an effective malaria control and elimination programme in Africa., Competing Interests: Declarations.

Background: Salmonella and Shigella are major enteric pathogens that cause diarrhea in children worldwide. They are pathogenic microbes that cause significant diarrheal morbidity and mortality in under five children in resource limited countries. Thus, this systemic review and meta-analysis aimed to investigate the prevalence of Salmonella and Shigella species and their multidrug resistance patterns in pediatric populations in Ethiopia., Methods: The articles were searched extensively in the electronic databases and grey literature using entry terms or phrases. Studies meeting the eligibility criteria were extracted in MS Excel and exported for statistical analysis into STATA version 14 software. The overall pooled prevalence of Salmonella and Shigella species was computed using a random-effects model. Heterogeneity was assessed using the Cochrane Q test and I 2 statistics with corresponding p-values. Publication bias was assessed using a funnel plot and Egger's test. In addition, sensitivity analysis was performed to determine the impact of individual studies on the pooled effect size., Result: Of a total of 742 identified studies, 89 studies were eligible for full-text analysis. Of 89 studies, 21 were included for meta-analysis involving 5318 study participants. These eligible studies reported a total of 593 bacterial isolates. The overall pooled prevalence of Salmonella and Shigella among pediatrics in Ethiopia was 10.70% (95% CI: 8.96-12.45), with substantial heterogeneity (I 2  = 82.1%, p < 0.001) across the studies. The pooled prevalence of Salmonella and Shigella individually among pediatrics in Ethiopia was 15.43% (95% CI: 10.42-20.72) and 15.83% (95% CI: 11.40-20.40), respectively. Moreover, the overall prevalence of multidrug resistance in Salmonella and Shigella isolates was 81.03% (95% CI: 77.39-84.67) with substantial heterogeneity of I 2 of 95%, p < 0.0001 between the pooled prevalence of the two species., Conclusion: The pooled prevalence of Salmonella and Shigella and their multidrug resistance were alarmingly high in pediatric. The initial empirical treatment of pediatrics patients remains challenging and results high prevalence of antimicrobial resistance. Thus, appropriate infection prevention and control strategies should be implemented and treatment should be directed based on antimicrobial stewardship protocols., Competing Interests: Declaration.

Background: Case identification remains a challenge to reaching the United Nations 95-95-95 targets for children with HIV. Although the World Health Organization approved oral mucosal HIV self-testing (HIVST) for children older than 2 years in 2019, there is little information on HIVST for pediatric case identification in Ethiopia., Setting: Nine health facilities across Ethiopia., Methods: We implemented a pilot program from November 2021 to April 2022 to assess acceptability and feasibility of using HIVST to screen children 2-14 years of adult index clients, (ie, parents/caregivers living with HIV and on antiretroviral therapy). HIV-positive adults who had children with unknown HIV status were given HIVST kits (OraQuick) to screen their children at home. Parents/caregivers were asked to report results telephonically and bring children screening positive to the health facility for confirmatory HIV testing. We defined HIVST acceptability as ≥50% of parents/caregivers accepting testing and ≥50% reporting results within 7 days of receiving a test kit. Feasibility was defined as ≥60% of children with a reactive HIVST receiving confirmatory testing and <5 serious social harms reported per 1000 kits distributed., Results: Overall, 1496 of 1651 (91%) parents/caregivers accepted HIVST kits to test their children at home and 1204 (71%) reported results within 7 days. Of 17 children (1%) with reactive results, 13 (76%) received confirmatory testing; of which 7 (54%) were confirmed to be HIV positive. One serious social harm was reported., Conclusions: Providing adult parents/caregivers with HIVST kits to screen their children at home is an acceptable and feasible strategy to reach untested children and improve pediatric case finding in a low prevalence setting., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 The Author(s).

Background: Otitis media is an inflammation of the middle ear that affects both adults and children, leading to hearing loss and impacting intellectual performance, especially in developing countries. Key factors contributing to its development include lack of vaccination, inadequate breastfeeding, overcrowding, and malnutrition. Major bacterial pathogens involved are Pseudomonas aeruginosa, Staphylococcus aureus, Proteus mirabilis, Klebsiella pneumoniae, Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.This systematic review and meta-analysis revealed the pooled prevalence of bacterial ear infections and multidrug resistance in Ethiopia., Methods: Thorough searches were conducted across electronic databases and grey literature using precise entry terms or phrases. Eligible studies were compiled into MS Excel and imported into STATA version 14 software for statistical analysis. The collective prevalence of bacterial ear infections and multidrug resistance patterns were calculated using a random-effect model, with heterogeneity assessed via the I 2 value. Publication bias was examined using a funnel plot and Egger's test. Sensitivity analysis was performed to gauge the impact of individual studies on the overall effect size., Result: Seventy studies met the criteria for qualitative analysis, with 14 selected for the meta-analysis. These studies reported a total of 3,667 bacterial isolates. The prevalence of bacterial ear infections varied significantly, ranging from 28.2% to 98.2% across individual studies. In this systematic review and meta-analysis, the pooled prevalence of bacterial ear infections in Ethiopia was found to be 73.39% (95% CI: 65.15-81.63), demonstrating substantial heterogeneity (I 2  = 98.5%, p < 0.001). Additionally, the pooled prevalence of multidrug resistance among bacterial ear infections was 72.45% (95% CI: 66.86-78.04). The most frequently identified isolate was Staphylococcus aureus, with a pooled prevalence of 68.87% (95% CI: 13.94-123.79), followed closely by Proteus spp. at 68.55% (95% CI: 3.15-140.26), Pseudomonas aeruginosa at 48.15% (95% CI: 1.84-94.45), and Escherichia coli at 37.15% (95% CI: 14.03-88.34)., Conclusion: The pooled prevalence of bacterial ear infections in Ethiopia is alarmingly high, accompanied by significant levels of multidrug resistance. These findings highlight the urgent need to reevaluate empirical treatment strategies due to the rising antimicrobial resistance., Competing Interests: Declarations.

Background and Aim: Leprosy is one of the most common skin neglected tropical diseases in Ethiopia posing social stigma, physical disability, deformity, discrimination, loss of social status, and poor quality of life in families. Hence, evidence-based collaborative inter-sectoral actions should be performed to reduce and eliminate its burden in endemic areas. Thus, the aim of this study was to assess the acid-fast positivity rate and associated factors of leprosy among suspected cases in Northeastern Ethiopia: a cross-sectional study., Method: A cross-sectional study was conducted from September 2022 to March 2023 among 256 leprosy-suspected cases selected using a simple random sampling technique. A semi-structured questionnaire was used to collect socio-demographic, clinical, and predictor variables of leprosy through face-to-face interviews. Skin slit specimens were collected and stained using Ziehl-Neelsen staining technique. STATA 17 was used for analysis. The scale reliability coefficient was checked using Cronbach's α and the goodness-of-fit test of the model was assessed by the Hosmer-Lemshow test. Moreover, bivariable and multivariable logistic regression were computed. Finally, variables with an adjusted odds ratio and their p  < 0.05 were taken as statistically significant., Result: The mean ± standard deviation of the age of participants was 43.25 ± 16.35. The overall, prevalence of acid-fast positivity among suspected cases was 19.6% (95% CI: 15.8%, 23.4%). Multivariable logistic regression analysis showed that sex being male ( p  = 0.045), rural residence ( p  = 0.047), not eating three times meals frequency ( p  = 0.014), not eating a balanced diet ( p  = 0.036), poor personal hygiene ( p  = 0.028), distant from health facility ( p  = 0.039), not washing hands usually ( p  = 0.013), presence of current co-infection ( p  = 0.002), type of leprosy ( p  = 0.004), and close contact with leprosy cases ( p  = 0.003) were more likely to be positive for leprosy., Conclusion: The prevalence of leprosy was remained high. Thus, early detection and treatment are necessary to reduce delayed diagnosis and hidden transmission of leprosy in the community. By addressing the driving factors through evidence-based intervention, we can significantly control the burden of leprosy in the affected communities, and improve their health outcomes and quality of life., Competing Interests: The authors declare no conflicts of interest., (© 2024 The Author(s).

Background: Tuberculosis (TB) is a preventable and treatable disease leading to the second death globally. The evolution of drug resistance in Mycobacterium tuberculosis (MTB), particularly rifampicin resistance (RR), has hampered TB control efforts. Thus, this study aimed to provide information regarding the magnitude of MTB and rifampicin resistance among patients tested using the GeneXpert method., Methods: A retrospective analysis was carried out at DTCSH. The study included TB registration logbook data from all patients who visited the hospital and were tested for MTB with the Xpert MTB/RIF assay from 2017 to 2024. The laboratory-based data were entered, cleaned, and analyzed using SPSS version 26 software. Multilogistic regression analysis was employed, and a p value ≤ 0.05 was considered statistically significant., Results: A total of 12,981 patient results were included, of which 8.9% (1160/12,981) were MTB-positive and 7.1% (82/1160) were RR. Individuals aged 15-29 years (AOR = 2.13; 95% CI = 1.55-2.93, p < 0.001), living in rural areas (AOR = 1.23; 95% CI = 1.08-1.41, p = 0.003), and HIV+ (AOR = 1.79; 95% CI = 1.48-2.33, p < 0.001) had a higher risk of developing tuberculosis. While RR was identified in 63.4% (52/82) of new, 24.4% (20/82) of re-treated, and 12.2% (10/82) of failed presumptive TB patients., Conclusion: In this study, MTB and RR trends were high. Productive age groups, rural populations, and HIV patients were at risk. To lessen the burden of this contagious and fatal disease, it is recommended to increase early diagnosis of drug-resistant TB and enhance infection control., (© 2024 The Author(s).

Background: Nasopharyngeal carriage of S. pneumoniae is a global health problem that has been associated with the emergence of severe disease and pathogen dissemination in the community. However, summary data on the carriage rate, antimicrobial susceptibility profile, and determinant factors is lacking., Method: Articles were extensively searched in bibliographic databases and gray literature using entry terms or phrases. Studies meeting eligibility criteria were extracted in MS Excel and exported to STATA version 17 software for statistical analysis. A random-effects model was used to compute the pooled magnitude of the nasal carriage of S. pneumoniae and its multidrug resistance. The heterogeneity was quantified by using the I 2 value. Publication bias was assessed using a funnel plot and Egger's test. Sensitivity analysis was done to assess the impact of a single study on the pooled effect size., Result: Of the 146 studies identified, 8 studies containing a total of 3223 children were selected for meta-analysis of the magnitude of the nasal carriage of S. pneumoniae and its multidrug resistance. The overall pooled prevalence of nasal carriage of S. pneumoniae and its MDR status in Ethiopian children was 32.77% (95%CI: 25.1, 40.44). and 31.22% (95%CI: 15.06, 46.84), respectively. The highest resistant pattern of S. pneumoniae was against tetracycline, which was 46.27% (95%CI: 37.75, 54.79), followed by 45.68% (95%CI: 34.43, 57.28) trimethoprim-sulfamethoxazole, while the least pooled prevalence was against chloramphenicol, which was 16.2% (95%CI: 9.44, 22.95). The pooled effect of age less than 5 years old (pooled OR = 1.97; 95% CI: 1.35, 2.88, P < 0.001), co-sleeping habit with others (pooled OR = 2.36; 95% CI: 1.77, 3.66; P < 0.001), sibling (pooled OR = 1.82; 95% CI: 1.14, 2.91, P = 0.01), history of hospitalization (pooled OR = 4.39; 95% CI: 1.86, 10.34, P = 0.001), and malnutrition (pooled OR = 2.18; 95% CI: 1.49, 3.19; P < 0.001) showed a statistical association with S. pneumoniae nasal carriage rate by using the random effect Sidik-Jonkman model., Conclusion: The magnitude of the nasopharyngeal carriage rate and multi-drug resistance status of S. pneumoniae alarms the need for immediate interventions such as strengthening antimicrobial stewardship programs, undertaking national antimicrobial surveillance, one-health initiatives, and national immunization programs., (© 2024.

This study examined the effects of different forage sources on the ruminal bacteriome, growth performance, and carcass characteristics of Hanwoo steers during the fattening stage. In Korea, where high-concentrate feeding is common, selecting suitable forage is crucial for sustainable beef production. Fifteen 23-month-old Hanwoo steers, weighing an average of 679.27 ± 43.60 kg, were fed the following five different forage sources: oat hay (OAT), rye silage (RYE), Italian ryegrass (IRS), barley forage (BAR), and rice straw silage (RSS), alongside 1.5 kg of dry matter concentrate daily for five months. Carcass traits were evaluated post-slaughter, and rumen fluid samples were analyzed using full-length 16S rRNA gene sequencing to determine the bacteriome composition. The forage source significantly affected the alpha-diversity indices and bacteriome biomarkers linked to the feed efficiency and ruminal fermentation. Differences in the backfat thickness and meat yield index were noted, with alpha-diversity indices correlating with carcass traits. The phylum Planctomycetota, especially the family Thermoguttaceae, was linked to nitrogen fixation in high-protein diets like IRS, while the genus Limimorpha emerged as a biomarker for the meat yield. These findings highlight the importance of forage selection during late fattening to optimize beef production, considering diet and bacteriome shifts.

Background: Malaria and undernutrition pose challenges for children in conflict-affected areas. Understanding the prevalence and risk factors for these issues in war-torn communities is important to effectively design aid efforts and select interventions. This study aimed to determine the prevalence and correlates of malaria and undernutrition among febrile children in northeast Ethiopia to help address these problems., Methods: A cross-sectional study was conducted from November 2022 to January 2023. Four hundred twenty-two children were enrolled using a systematic random sampling technique. Data on associated factor variables were collected via questionnaire. Capillary blood samples were collected from each child to prepare thick and thin blood films, which were stained with Giemsa and examined microscopically. Height and weight measurements were also taken using a meter and a standard calibrated balance. The data were analyzed in SPSS 26.0 using bivariable and multivariable logistic regression to determine associations between correlates, malaria infection, and undernutrition. Statistical significance was set at p < 0.05., Results: The overall malaria prevalence among screened children at temporary sites in the conflict-affected areas of Northeast Ethiopia was 65.9% (278/422). Plasmodium falciparum, P. vivax, and mixed infections accounted for 74.1%, 19.8%, and 6.1% of the cases, respectively. The presence of stagnant water (P<0.01), improper utilization of ITN, inadequate number of ITNs per family size (P<0.01), and absence of environmental management (P<0.01) were independent predictors of malaria. On the other hand, the overall undernutrition prevalence was 54.7% (231/422), including 26.5% underweight, 16.8% stunted, and 11.4% wasted. Dietary diversity score (P<0.01), meal frequency (P<0.01), and confirmed malaria infection (P<0.01) were significantly associated with underlnutrition., Conclusion: Both malaria and undernutrition burdens were high among the children in this study. The findings suggest combined prevention measures for malaria and undernutrition should be strengthened in this region., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Debash et al.

Background: Scabies disproportionately affects people in resource-poor areas. Clinical diagnosis risks misdiagnosis due to resemblance to other skin diseases, but laboratory confirmation improves accuracy. Scabies allow for secondary bacterial infections. Associated bacteria exacerbate scabies and antibiotic resistance. Ethiopian scabies diagnosis relies solely on clinical exams without confirming parasites or investigating secondary bacterial infections. This study aims to identify parasites via scraping, isolate secondary bacteria, and evaluate their antibiotic susceptibility profiles., Methods: A hospital based cross-sectional study was conducted from September 2022 to July 2023 among scabies suspected patients who visited the dermatology clinic at Borumeda General Hospital in Northeast Ethiopia. A systematic random sampling technique was used to select 422 study participants. Socio-demographic, hygiene, and clinical characteristics data were collected via face-to-face interviews and observation. Skin scrapings for parasitological investigations and swab samples for microbiological investigations were collected and transported for analysis and drug susceptibility testing. Descriptive statistics and logistic regression analysis were employed to assess risk factors., Result: Among 422 skin scraping samples, 156 (37.0%) cases of scabies were microscopically confirmed. Bed-sharing and having contact history were independent predictors of microscopically confirmed scabies. The prevalence of secondary bacterial infections among scabies-confirmed patients was 35.9% (56/156). The most prevalent bacterial species were Staphylococcus aureus, coagulase-negative staphylococci, and Streptococcus pyogenes. Tetracycline for Gram-positive bacteria and ampicillin for Gram-negative bacteria showed the highest rate of resistance. In both Gram-positive and Gram-negative strains, multidrug resistance was also observed., Conclusion: This study found that over one-third of skin scrapings tested positive for scabies. Additionally, more than one-third of scabies cases were complicated by secondary bacterial infections. Improved scabies diagnosis and consideration of secondary bacterial infections are important for better controlling this neglected tropical disease., (© 2024. The Author(s).)

We investigate the dynamics of comb-like polymer translocation through a nanochannel using three-dimensional Langevin dynamics simulations based on a coarse-grained chain model. A comprehensive set of simulations are performed to examine the effects of system parameters such as the grafting density ρ of the side chains, the polymer chain length, the nanochannel dimensions, and the magnitude of the pulling force on the translocation dynamics. For a given polymer chain length, keeping the backbone length is constant while varying ρ , we have found that the dependence of the mean translocation time⟨τ⟩on ρ is non-monotonic, with a maximum translocation time for a specific ρ at which the translocation is the slowest. The simulation results also show that⟨τ⟩is not significantly affected by the channel width above a certain radius, while the comb-like polymer translocation is hindered by a narrower channel due to increased interactions between the chain monomers and the channel. In addition,⟨τ⟩increases linearly with the nanochannel length. A linear scaling relationship between the mean translocation time⟨τ⟩and the chain length N of polymer is obtained,⟨τ⟩∼N. Similarly, the dependence of⟨τ⟩on the backbone chain sizeNbbhas a quasi-linear dependence,⟨τ⟩∼Nbb. On the other hand, the translocation velocity v follows a power-law relationship with the polymer chain length N asv∼N-1. The mean translocation time also shows an inverse linear relationship with the magnitude of the pulling force F ,⟨τ⟩∼F-1. The power-law relationships discovered in this study contribute to the fundamental understanding of the comb polymer translocation dynamics and to establishing a framework for further investigations in this field., (Creative Commons Attribution license.)

Background: Antibiotic-resistant Salmonella is one of the main public health concerns in the world. Isolation of Salmonella in abattoirs has been considered the core source of infection in the community from meat. Still, there is limited information on the contamination rate of cattle carcasses., Objective: This study aimed to document the occurrence and antimicrobial susceptibility profile of Salmonella species recovered from cattle carcass and abattoir personnel at Dessie, municipality abattoir, Northeast Ethiopia: METHODS: A total of 336 carcass swabs of abdomen, neck, and hind limb from cattle carcasses and 24 stool samples were collected from abattoir personnel using a systematic sampling method from February to April 2019. The collected samples were transported using Cary-Blair transport media and cultivated on Selenite cysteine F-broth, Brilliant green agar, and Xylose-lysine deoxycholate agar plates to isolate Salmonella species. Gram stain, colony morphology, and biochemical tests were performed to identify the isolated bacteria. An antimicrobial susceptibility test for Salmonella was performed using the Kirby-Bauer Disc Diffusion method. Descriptive statistics; both bivariable and multivariable logistic regression analysis was performed using SPSS version 25 software. P-value < 0.05 at 95% CI was considered statistically significant., Results: The prevalence of salmonella species was 8%(27/336) from all samples.'The prevalence of Salmonella isolates in cattle carcass and abattoir personnel was 8%(25/312) and 8.3%(2/24) respectively. The antimicrobial test showed that Salmonella species were 100% resistant to ampicillin, 59.3% to trimethoprim-sulfamethoxazole, 59.3% to tetracycline, and 55.6% to amoxicillin/clavulanate. From the total antimicrobial tested bacteria, 81.5%(22/27) were resistant to three and above classes of antibiotics (drug classes). Unwashed knives, carcasses, and hands of butchers during slaughtering were significantly associated (p < 0.05) with Salmonella found in carcasses., Conclusions: Salmonella isolation rates from cattle carcasses were high, with the bacteria showing notable resistance to most tested antibiotics. Poor hygiene practices, unsanitized equipment, and unhygienic beef processing were contributing factors., (© 2024. The Author(s).)

Background: Antimicrobial resistance is a major global public health issue. Infections caused by resistant species are associated with higher mortality rates, longer hospital stays, medication failure, and rising medical costs. The World Health Organisation has declared multidrug resistance-associated infections as an epidemic of public health concern., Objective: This study aimed to evaluate the antimicrobial resistance profile and associated factors of hospital-acquired Gram-negative bacterial pathogens among hospitalized patients in Northeast Ethiopia., Materials and Methods: A health facility-based cross-sectional study was conducted among hospitalized patients from March 2021 to February 2022. About 810 clinical specimens were collected, transported, and processed from admitted patients following the standard bacteriological procedures. The clinical samples were inoculated onto blood agar, MacConkey agar, and chocolate agar. Furthermore, the species identification was done using gram reactions, colony morphology, and color and biochemical tests. Antimicrobial susceptibility tests, extended-spectrum beta-lactamase, and carbapenemase production were performed as per the clinical laboratory standard institute guidelines. For analysis, the information was entered into Epi-data and exported to SPSS. A P value of < 0.05 with a 95% confidence interval was considered as a statistically significant association., Results: Out of 810 clinical specimens, 285/810 (35.2%) developed bacterial infections. From the isolated bacteria, E. coli was the predominant bacteria accounting for 78/285 (27.4%) followed by K. pneumoniae, 69/285(24.42%), whereas P. vulgaris accounted for the least, 7/285 (2.5%). Overall, 132/285 (46.3%) and 99/285 (34.7%) of culture-positive patients were infected by extended-spectrum beta-lactamase and carbapenemase-producing bacteria. The overall multidrug resistance rate of the isolated bacteria was 89.4%. The highest antibiotic resistance rates were detected for doxycycline (92.9%), amoxicillin-clavulanic acid (83.9%), and ampicillin (93%). The least antibiotic resistance rate was observed for meropenem at 41.1% and amikacin at 1.7%, respectively., Conclusions and Recommendations: In the study area, significant health concerns include a range of hospital-acquired bacterial infections associated with elevated rates of multidrug resistance, Extended-spectrum beta-lactamase (ESBL), and carbapenemase-producing bacterial pathogens. Consequently, it is recommended to conduct drug-susceptibility testing of isolates and molecular detection at a national level to optimize antibiotic usage for treating prevalent bacterial infections in this area., (© 2024.

This study aimed to identify important non-genetic factors and estimate genetic parameters for efficiency-related traits in Boer x Central Highland goats. The genetic parameters were estimated using the Average Information Restricted Maximum Likelihood algorithm using the WOMBAT program fitting animal model. The least-squares means for growth efficiency from birth to 3 months (GE1), 3-6 months (GE2), 6-12 months (GE3), relative growth rate from birth to 3 months (RGR1), 3-6 months (RGR2) and 6-12 month (RGR3) were 294.0 ± 5.06, 36.6 ± 1.20, 44.9 ± 1.81, 1.46 ± 0.01, 0.32 ± 0.01 and 0.19 ± 0.01, respectively. Birth type, blood level, sex of the kid, and year of kidding had a sizable effect on efficiency-related traits. About 18, 3.0, 23, 20, and 12% of the phenotypic variation in GE2, GE3, RGR1, RGR2, and RGR3 was explained by the direct additive genetic effect. Except for RGR3, all investigated traits were under the influence of maternal genetic effect, and maternal heritability ranged from 0.09 to 0.17. The total heritability estimate depicts that slow genetic progress would be expected from selection. Nevertheless, even with this level of heritability, selection for efficiency-related traits would improve the efficiency of chevon production as these traits are economically important traits. Nearly six-months of age was when farmers sold Boer crossbred goats. Therefore, improving the growth efficiency till the marketing age (GE2) in such a scenario could increase the production efficiency., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Tesema et al.

Introduction: Tuberculous lymphadenitis (TBLN) is an infection of the lymph node caused by Mycobacterium tuberculosis. Histological diagnoses of presumptive patients are often accompanied by cytomorphological features. However, the sensitivities of these features are often precluded by the variable degrees of narrative similarities compared to other diagnostic modalities., Objective: The aim of this study was to investigate and compare the cytomorphological and clinical features of presumptive TBLN patients with bacteriological detection methods., Methods: A similar cohort of TBLN patients from our previous study who were enrolled prospectively from the ALERT Specialized Hospital, Addis Ababa, Ethiopia, was considered for this analysis. SPSS version 26 was used for data analysis. Descriptive analysis was conducted to characterize the study population using the independent variable and presented with frequency tables. The chi-square test was used to measure the association. A P-value of < 0.05 was considered statistically significant., Results: Using FNAC, 60/126 (47.6%) of the participants were reported to have features consistent with TB. Of the total FNAC-positive cases, many (30/60 and 27/60) showed pattern B (caseous necrosis only) and pattern C (epithelioid granuloma with caseous necrosis), respectively. Strong concordance was observed in Pattern A (abundant caseous necrosis with few epithelioid macrophages) followed by patterns B and C with GeneXpert and MGIT culture (P value < 0.001). Night sweats and alcohol intake were shown to correlate with positive cases as reported by FNAC (P value = 0.008 respectively), GeneXpert (P value = 0.02 & 0.001), and culture methods (P-value = < 0.001 & 0.002)., Conclusion: Cytomorphological features, particularly patterns A, B, and C, could be considered in the diagnosis of TBLN given their comparable outcomes with bacteriological detection methods. On another note, we recommend that due care and attention be given when treating TBLN patients based solely on clinical presentation, as these diagnostics may be prone to false results, leading to inappropriate administration of anti-TB drugs and other consequences., (© 2024.

Introduction: Hypertension has emerged as a significant public health concern, ranking among the leading causes of mortality in low- and middle-income countries. Moreover, it is closely associated with structural and functional alterations in hematopoietic cells. Therefore, this study aimed to evaluate the hematological parameters of hypertensive patients in Northeast Ethiopia., Methods: A comparative cross-sectional study was conducted from January to March 2023, involving 248 participants. This included 124 hypertensive patients and 124 apparently healthy controls selected using a systematic random sampling technique. Socio-demographic and clinical data were collected through a structured questionnaire, and anthropometric measurements were obtained following established guidelines. Ethical approval was obtained from the Ethical Review Committee of the College of Medicine and Health Sciences at Wollo University. After obtaining informed consent, approximately 5 ml of venous blood was drawn from each participant for complete blood count and fasting blood glucose analysis, performed using the Mindray BC-3000 Plus hematology analyzer and the DIRUI CS-T240 automated clinical chemistry analyzer, respectively. Data analysis involved independent t-tests, Mann-Whitney U-tests, correlation tests, and logistic regression. A p-value of <0.05 was considered statistically significant., Results: The study found that white blood cell count, platelet count, platelet distribution width, red cell distribution width, and mean platelet volume were significantly higher in hypertensive patients compared to the control group ( p  < 0.05). Conversely, red blood cell count, hematocrit, and hemoglobin levels were significantly higher in the control group than in hypertensive patients ( p  < 0.05). Additionally, white blood cells and platelets exhibited a positive correlation with systolic and diastolic blood pressure ( p  < 0.05), while red blood cell count, hematocrit, and hemoglobin demonstrated a negative correlation with blood pressure indices and body mass index. Anemia was observed in 20.2 % of hypertensive patients. Notably, an abnormal body mass index (AOR: 3.5, 95 % CI: 1.3-9.6, p  = 0.011) and high systolic blood pressure (AOR: 4.6, 95 % CI: 1.3-15.5, p  = 0.013) were significantly associated with anemia among hypertensive patients., Conclusion: This study identified significant differences in various hematological parameters between hypertensive patients and the control group. Routine assessments of hematological parameters should be considered to effectively manage hypertension-related complications in hypertensive patients., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Purpose: Intensive care units (ICUs) in low- and middle-income countries have high mortality rates, and clinical data are needed to guide quality improvement (QI) efforts. This study utilizes data from a validated ICU registry specially developed for resource-limited settings to identify evidence-based QI priorities for ICUs in Ethiopia., Materials and Methods: A retrospective cohort analysis of data from two tertiary referral hospital ICUs in Addis Ababa, Ethiopia from July 2021-June 2022 was conducted to describe casemix, complications and outcomes and identify features associated with ICU mortality., Results: Among 496 patients, ICU mortality was 35.3%. The most common reasons for ICU admission were respiratory failure (24.0%), major head injury (17.5%) and sepsis/septic shock (13.3%). Complications occurred in 41.0% of patients. ICU mortality was higher among patients with respiratory failure (46.2%), sepsis (66.7%) and vasopressor requirements (70.5%), those admitted from the hospital ward (64.7%), and those experiencing major complications in the ICU (62.3%)., Conclusions: In this study, ICU mortality was high, and complications were common and associated with increased mortality. ICU registries are invaluable tools to understand local casemix and clinical outcomes, especially in resource-limited settings. These findings provide a foundation for QI efforts and a baseline to evaluate their impact., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Background: Urinary tract infections are common bacterial and fungal infections in humans, occurring both in the community and in immunocompromised patients in healthcare settings. Urinary tract infections have a significant health impact on HIV-infected patients. Nowadays, drug-resistant pathogens are widespread poses a serious clinical risk, and causes urinary tract infection. The common agents of bacteria and fungi that cause urinary tract infection are Escherichia coli followed by Klebsiella pneumonia, Staphylococcus saprophyticus, Enterococcus faecalis, group B streptococcus, Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureus and Candida. albicans. This study aimed to investigate uro-pathogen, multidrug resistance pattern of bacteria, and associated factors of community-acquired urinary tract infection among HIV-positive patients attending antiretroviral therapy in Dessie comprehensive specialized hospital, Northeast Ethiopia from February 1, 2021, to March 30, 2021., Methods: An institutional-based cross-sectional study was conducted at Dessie Comprehensive Specialized Hospital. Socio-demographic and clinical data were collected by using structured questionnaires from HIV patients suspected of community-acquired urinary tract infections. About 10 ml of clean-catch midstream urine was collected and inoculated into Blood agar, MacConkey, and Cysteine lactose electrolyte deficient media. Yeasts were identified by using Gram stain, germ tube test, carbohydrate fermentation, assimilation tests, and chromogenic medium. Gram stain and biochemical tests were performed to identify isolates and an antimicrobial susceptibility pattern was performed on disc diffusion techniques. Data were entered and analyzed using SPSS version 25. Both bivariate and multivariable logistic regression analysis was performed and a P value of < 0.05 with an adjusted odds ratio with their 95% confidence interval (CI) was used as statistically significant associations., Results: From the total 346 study participants, 92 (26.6%) were culture positive 75 (81.52%) were bacterial and 17 (18.48%) were fungal pathogens. From a total of 75 bacteria isolates 51(68%) were Gram-negative bacteria and the most commonly isolated bacteria were E. coli 16 (21.33%) followed by K. pneumoniae 11(14.67%) and enterococcus species 10(10.87. Of the 17 fungal isolates of fungi, 8(47.1%) were represented by C. tropicalis. Of the isolated bacteria, 61(81.3%) were resistant to three and above classes of antibiotics (drug classes). About 13 (81.3%) of E. coli, 9(81.8%) of K. pneumoniae, 8(80%) of Enterococcus species, 7 (77.8%) of P. aeruginosa, and CoNs 7(87.5%) were the most frequently exhibited three and above classes of antibiotics (multi-drug resistance). Amikacin and gentamicin were effective against Gram-negative Uro-pathogens. Participants aged>44year, female, being daily labor, being farmer, unable to read and write, patients with CD4 count of ≤ 200 cells/mm3 and CD4 count of 201-350 cells/mm3, who had chronic diabetics, patients having a history of hospitalization and who had urgency of urinations were statistically significant association with significant urinary tract infections., Conclusion: The burden of community-acquired urinary tract infections among HIV patients is alarmingly increased. Therefore, behavior change communications might be considered for promoting the health status of HIV patients. Moreover, CD4 level monitoring and therapeutics selection based on microbiological culture are quite advisable for the management of urinary tract infections of HIV patients., Competing Interests: The authors declare that they have no competing interest., (Copyright: © 2024 Tilahun et al.

Introduction: The treatment response of multi-drug resistance tuberculosis (MDR-Tuberculosis) patients is mainly dictated by the sputum culture conversion. An earlier culture conversion is a remarkable indicator of the improvement in the treatment response. In this study, we aimed to determine the time to culture conversion and its associated factors among MDR-Tuberculosis patients in All Africa Leprosy, Tuberculosis and Rehabilitation Training Center (ALERT) Hospital, Addis Ababa, Ethiopia., Methods: A retrospective cohort study was conducted on 120 MDR-Tuberculosis patients attending ALERT Hospital from 2018-2022. Kaplan-Meier methods were used to determine the time to initial sputum culture conversion. All relevant laboratory, socio-demographic characteristics, and other clinical data were collected by chart abstraction using a structure data extraction form. The log-rank test was used to determine the survival rate. To identify the predictors of culture conversion, bivariate and multivariate Cox proportional hazard regression analysis was used. The hazard ratio (HR) with a 95% confidence interval was used to estimate the effect of each variable on the initial culture conversion. A test with a P value of < 0.05 was considered statistically significant., Results: From the total of 120 study participants, 89.2% (107/120) have shown a successful culture conversion. The median age of the participants was 30 years (IQR = 12). The study participants were followed for 408.6 person-months (34.05 person-years). The median time to initial sputum culture conversion was 80 days. The median time to initial sputum culture conversion among HIV-positive and HIV-negative participants was 61 days (IQR = 58-63.5) and 88 days (IQR = 75-91), respectively. HIV-negative and patients with previous treatment history were shown to be the predictor for a prolonged time to initial sputum culture conversion, (aHR = 0.24 (95% CI: 0.1-0.4), P value <0.001) and (aHR = 0.47 (95% CI: 0.31-0.71), P value <0.001) respectively., Conclusion: The median time to sputum culture conversion for HIV positive was found to be 61 days in our study. Notably, patients with a history of previous anti-tuberculosis treatment, HIV-negative status, and higher bacillary load at baseline exhibited delayed culture conversion. These findings underscore the importance of considering such patient characteristics in the management of MDR-TB cases, as tailored interventions and close monitoring may lead to more favorable treatment outcomes. By identifying individuals with these risk factors early in the treatment process, healthcare providers can implement targeted strategies to optimize patient care and improve overall treatment success rates in MDR-TB management programs., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Abebe et al.

Objective: Hepatitis B virus and hepatitis C virus are the leading causes of global liver-related morbidity and mortality. Waste handlers are one of the high-risk groups for hepatitis B virus and hepatitis C virus acquisition. Thus, the aim of this study was to assess the pooled prevalence of hepatitis B virus and hepatitis C virus among waste handlers in Ethiopia., Methods: Articles were extensively searched in bibliographic databases and gray literature using entry terms or phrases. Studies meeting eligibility criteria were extracted in MS Excel and exported to STATA version 14 software for statistical analysis. A random-effects model was used to compute the pooled magnitude of hepatitis B virus and hepatitis C virus. Heterogeneity was quantified by using the I 2 value. Publication bias was assessed using a funnel plot and Egger's test. Sensitivity analysis was performed to assess the impact of a single study on pooled effect size., Result: Of the 116 studies identified, 8 studies were selected for meta-analysis. All studies reported hepatitis B virus, while 5 studies reported hepatitis C virus infection among waste handlers. The overall pooled prevalence of hepatitis B virus and hepatitis C virus infection among waste handlers in Ethiopia was 5.07% (2.0-8.15) and 1.46% (0.52-2.4), respectively. Moreover, the pooled prevalence of lifetime hepatitis B virus exposure among Ethiopian waste handlers was 33.98% (95% CI: 21.24-46.72). Hepatitis B virus and hepatitis C virus infection were not statistically associated with the type of waste handlers, that is, there was no difference between medical and nonmedical waste handlers., Prospero Registration: CRD42023398686., Conclusion: The pooled prevalence of hepatitis B virus and hepatitis C virus infection among waste handlers in Ethiopia was intermediate and moderate, respectively. This showed that there is a strong need to scale up preventive efforts and strategic policy directions to limit the spread of these viruses. Moreover, we also conclude that handling healthcare and domestic waste is associated with a similar risk of hepatitis B virus and hepatitis C virus infection., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Background: Preeclampsia (PE), an obstetric disorder, remains one of the leading causes of maternal and infant mortality worldwide. In individuals with PE, the coagulation-fibrinolytic system is believed to be among the most significantly impacted systems due to maternal inflammatory responses and immune dysfunction. Therefore, this systematic review and meta-analysis aimed to assess the association of prothrombin time (PT), thrombin time (TT) and activated partial thromboplastin time (APTT) levels with preeclampsia., Methods: This systematic review and meta-analysis was conducted in accordance with the PRISMA guidelines. Articles relevant to the study, published from July 26, 2013, to July 26, 2023, were systematically searched across various databases including PubMed, Scopus, Embase, and Hinari. The methodological quality of the articles was evaluated using the Joanna Briggs Institute critical appraisal checklist. Utilizing Stata version 14.0, a random-effects model was employed to estimate the pooled standardized mean difference (SMD) along with the respective 95% CIs. The I 2 statistics and Cochrane Q test were utilized to assess heterogeneity, while subgroup analyses were performed to explore its sources. Furthermore, Egger's regression test and funnel plot were employed to assess publication bias among the included studies., Results: A total of 30 articles, involving 5,964 individuals (2,883 with PE and 3,081 as normotensive pregnant mothers), were included in this study. The overall pooled SMD for PT, APTT, and TT between PE and normotensive pregnant mothers were 0.97 (95% CI: 0.65-1.29, p < 0.001), 1.05 (95% CI: 0.74-1.36, p < 0.001), and 0.30 (95% CI: -0.08-0.69, p = 0.11), respectively. The pooled SMD indicates a significant increase in PT and APTT levels among PE patients compared to normotensive pregnant mothers, while the increase in TT levels among PE patients was not statistically significant., Conclusions: The meta-analysis underscores the association between PE and prolonged PT and APTT. This suggests that evaluating coagulation parameters like PT, APTT, and TT in pregnant women could offer easily accessible and cost-effective clinical indicators for assessing PE. However, multicenter longitudinal studies are needed to evaluate their effectiveness across various gestational weeks of pregnancy., (© 2024. The Author(s).)

Introduction: Medicinal plants, rich in phytochemicals like phenolic acids, flavonoids, and tannins, offer potential benefits in enhancing productivity, quality, and animal health. Amla fruit ( Phyllanthus emblica ) is one such plant with promising attributes. This study aimed to investigate the impact of fresh Amla fruit (FAF) supplementation on ruminal microbial composition and its correlation with rumen fermentation in lactating dairy cows., Methods: The study employed a repeated crossover design involving eight ruminally cannulated mid-lactation Holstein dairy cows. Animals received varying levels of fresh Amla fruit supplementation (0, 200, 400, and 600 g/d)., Results: When 400 g/d of FAF was added to the diet, there was a significant increase in the relative abundance of Firmicutes ( p  = 0.02). However, at 200 g/d, the relative abundance of ruminal Bacteroidota was higher than the 0 and 400 g/d FAF supplementation ( p  < 0.01). LEfSe analysis identified distinct taxa, such as Clostridia vadinBB60 in the 200 g/d group, Oscillospiraceae in the 400 g/d group, and Elusimicrobium in the 600 g/d group. Notably, the random forest species abundance statistics identified Oscillospiraceae V9D2013 as a biomarker related to milk yield. Oscillospiraceae, Bacilli RF39, norank&#95;f Prevotellaceae , and Bifidobacterium were positively correlated with ruminal total VFA and molar proportion of propionate, while Rikenellaceae RC9 gut group and Clostridia vadinBB60 were negatively correlated., Discussion: FAF supplementation affects the abundance of beneficial microbes in a dose-dependent manner, which can improve milk yield, efficiency, rumen health, desirable fatty acids, and animal health., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The author(s) declared that they were an editorial board member of Frontiers, at the time of submission. This had no impact on the peer review process and the final decision., (Copyright © 2024 Tilahun, Ma, Callaway, Xu and Bu.)

Background: Urinary tract infections, a prevalent global infectious disease, are clinical issues not well studied in HIV-positive individuals. UTIs have become a global drug resistance issue, but the prevalence and antibiotic susceptibility patterns of UTI-causing bacteria among HIV patients in Tigray, Ethiopia, are poorly understood. This study aims to identify the prevalence of UTI-causing bacteria, their antibiotic susceptibility patterns, and associated risk factors in HIV patients attending ART clinics at Mekelle General Hospital and Ayder Comprehensive Specialized Hospital in Tigray, Northern Ethiopia., Method: Clean-catch midstream urine samples (10-15 mL) were collected from HIV patients who are attending ART clinics at Mekelle General Hospital and Ayder Comprehensive Specialized Hospital. Samples were analyzed based on standard microbiological protocols using cysteine-lactose electrolyte deficient (CLED) agar. Pure colonies of bacterial isolates were obtained by sub-culturing into Mac-Conkey, Manitol Salt agar and blood agar plates. The bacterial isolates were then identified using macroscopic, microscopic, biochemical, and Gram staining methods. Gram-negative bacteria were identified using biochemical tests like triple sugar iron agar, Simon's citrate agar, lysine iron agar, urea, motility test, and indol test, whereas Gram-positive isolates were identified using catalase and coagulase tests. The Kirby-Bauer disk diffusion technique was used to analyze the antimicrobial susceptibility pattern of bacterial isolates. Data was analyzed using SPSS version 25.0., Results: Among the 224 patients, 28 (12.5%) of them had been infected by UTIs-causing bacteria. E. coli was the dominant bacterium (16 (57%)) followed by K. pneumoniae (4 (14%)), and S. aureus (3 (11%)). Of the total bacterial isolates, 22 (78.6%) of them developed multi-drug resistance. All Gram-positive (100%) and 75% of Gram-negative bacterial isolates were found to be resistant to two or more drugs. Patients with a history of UTIs, and with CD 4 count < 200 cells/ mm 3 , were more likely to have significant bacteriuria. Compared to male patients, female patients were more affected by the UTIs-causing bacteria. More than 93% of the UTIs-causing bacterial isolates were susceptible to nitrofurantoin, ceftriaxone, ciprofloxacin, and gentamycin; whereas they are highly resistant to ampicillin (96%), cotrimoxazole (82%) and tetracycline (71%)., Conclusions: Most of the bacterial isolates were highly resistant to ampicillin, cotrimoxazole, and tetracycline. Female patients were more affected by the UTIs causing bacteria. The highest prevalence (12.5%) of UTIs in HIV patients needs special attention for better management and monitoring. Previous UTI history and immune suppression are predictors of UTIs, highlighting the need for intervention measures involving molecular studies to identify resistant bacteria genes and promote patient immune reconstitution., (© 2024.

Background: Bacterial pneumonia can affect all age groups, but people with weakened immune systems, young children, and the elderly are at a higher risk. Streptococcus pneumoniae, Klebsiella pneumoniae, Haemophilus influenzae, and Pseudomonas aeruginosa are the most common causative agents of pneumonia, and they have developed high MDR in recent decades in Ethiopia. This systematic review and meta-analysis aimed to determine the pooled prevalence of bacterial pneumonia and multidrug resistance in Ethiopia., Methods: The articles were searched extensively in the electronic databases and grey literature using entry terms or phrases. Studies meeting the eligibility criteria were extracted in MS Excel and exported for statistical analysis into STATA version 14 software. The pooled prevalence of bacterial pneumonia and multidrug resistance were calculated using a random-effects model. Heterogeneity was assessed by using the I 2 value. Publication bias was assessed using a funnel plot and Egger's test. A sensitivity analysis was done to assess the impact of a single study on the pooled effect size., Result: Of the 651 studies identified, 87 were eligible for qualitative analysis, of which 11 were included in the meta-analysis consisting of 1154 isolates. The individual studies reported prevalence of bacterial pneumonia ranging from 6.19 to 46.3%. In this systematic review and metanalysis, the pooled prevalence of bacterial pneumonia in Ethiopia was 37.17% (95% CI 25.72-46.62), with substantial heterogeneity (I 2  = 98.4%, p < 0.001) across the studies. The pooled prevalence of multidrug resistance in bacteria isolated from patients with pneumonia in Ethiopia was 67.73% (95% CI: 57.05-78.40). The most commonly isolated bacteria was Klebsiella pneumoniae, with pooled prevalence of 21.97% (95% CI 16.11-27.83), followed by Streptococcus pneumoniae, with pooled prevalence of 17.02% (95% CI 9.19-24.86), respectively., Conclusion: The pooled prevalence of bacterial isolates from bacterial pneumonia and their multidrug resistance were high among Ethiopian population. The initial empirical treatment of these patients remains challenging because of the strikingly high prevalence of antimicrobial resistance., (© 2024. The Author(s).)

Background: Despite the well-established benefits of early initiation of breastfeeding and exclusive breastfeeding for the first six months to promote optimal neonatal and child health, evidence indicates that in Ethiopia, a significant number of newborns initiate breastfeeding late, do not adhere to exclusive breastfeeding (EBF) for the recommended duration, and instead are fed with bottles., Objective: To determine the proportion of delayed initiation of breast milk, exclusive breastfeeding, and its individual and community-level predictors among mothers in Ethiopia., Methods: A secondary data analysis was done using the 2019 Ethiopian Mini Demographic Health Survey data. We examined a weighted sample of 2,012 children born within the past 24 months and 623 children aged 0-5 months at the time of the survey. The data analysis was done using STATA version 15. To understand the variation in delayed initiation and exclusive breastfeeding, statistical measures such as the Intraclass correlation coefficient, median odds ratio, and proportional change in variance were calculated. We employed a multilevel mixed-effects logistic regression model to identify predictors for each outcome variable. Statistical significance was determined with a p-value < 0.05., Results: The proportion of delayed initiation of breast milk and exclusive breastfeeding were 24.56 and 84.5%, respectively. Women aged 34-49 years old (AOR = 0.33: 95% CI; 0.15-0.72), having a television in the house (AOR = 0.74: 95%CI; 0.33-0.97), delivered by cesarean section (AOR = 3.83: 95% CI; 1.57-9.32), and resided in the Afar regional state (AOR = 1.43: 95%CI; 1.03-12.7) were significantly associated with delayed initiation of breast milk. On the other hand, attended primary education (AOR = 0.67: 95%CI; 0.35-0.99), secondary education (AOR = 0.34: 95%CI; 0.19-0.53), women whose household headed by male (AOR = 0.68; 95% CI; 0.34-0.97), and rural residents (AOR = 1.98: 95%CI; 1.09-3.43) were significantly associated with exclusive breastfeeding practice., Conclusion: Health promotion efforts that encourage timely initation of breast milk and promote EBF, focused on young mothers, those who gave birth through cesarean section, and those residing in urban and the Afar regional state. Furthermore, government health policymakers and relevant stakeholders should consider these identified predictors when revising existing strategies or formulating new policies., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Abebe et al.

Introduction: Inflammatory bowel disease (IBD) poses a growing global burden, necessitating the discovery of reliable biomarkers for early diagnosis. The clinical significance of dysregulated expression of long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs) in diagnosing IBD has not been well established. Thus, our study aimed to investigate the diagnostic value of lncRNAs and circRNAs for IBD based on currently available studies., Methods: A comprehensive search was carried out in diverse electronic databases, such as PubMed, Embase, Scopus, Science Direct and Wiley Online Library to retrieve articles published until October 30, 2023. Stata 17.0 software was employed to determine pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic ratio (DOR), and area under the curve (AUC). Heterogeneity, subgroup analysis, and meta-regression were explored, and publication bias was assessed using Deeks' funnel plot. Fagan's nomogram and likelihood ratio scattergram were employed to evaluate the clinical validity., Result: A total of 11 articles encompassing 21 studies which involved 1239 IBD patients and 985 healthy controls were investigated. The findings revealed lncRNAs exhibit high level of pooled sensitivity 0.94 (95% CI: 0.87-0.97) and specificity 0.99 (95% CI: 0.89-1.00), along with PLR, NLR, DOR, and AUC values of 64.25 (95% CI: 7.39-558.66), 0.06 (95% CI: 0.03-0.13), 1055.25 (95% CI: 70.61-15770.77), and 0.99 (95% CI: 0.97-0.99), respectively. Conversely, CircRNAs showed moderate accuracy in IBD diagnosis, with sensitivity of 0.68 (95% CI: 0.61-0.73), specificity of 0.73 (95% CI: 0.65-0.79), PLR of 2.47 (95% CI: 1.94-3.16), NLR of 0.45 (95% CI: 0.38-0.53), DOR of 5.54 (95% CI: 3.88-7.93), and AUC value of 0.75 (95% CI: 0.71-0.79). Moreover, findings from subgroup analysis depicted heightened diagnostic efficacy when employing lncRNA H19 and a large sample size (≥100), with notable efficacy in diagnosing both ulcerative colitis (UC) and Crohn's disease (CD)., Conclusion: LncRNAs exhibit high diagnostic accuracy in distinguishing patients with IBD from healthy controls signifying their possible use as potential biomarkers, while circRNAs showed moderate diagnostic accuracy. Nevertheless, to validate our findings and confirm the clinical utility of lncRNAs and circRNAs in IBD diagnosis, a large pool of prospective and multi-center studies should be undertaken., Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO, identifier CRD42023491840., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Belete, Tadesse, Tilahun, Gedefie, Shibabaw, Mulatie, Wudu, Gebremichael, Debash, Alebachew and Alemayehu.)

Background: Dyslipidemia is responsible for more than half of the global ischemic heart disease (IHD) and more than 4 million deaths annually. Assessing the prevalence of dyslipidemia can be crucial in predicting the future disease development and possible intervention strategies. Therefore, this systematic review and meta-analysis was aimed at assessing the pooled prevalence of dyslipidemia in HIV-infected patients., Methods: Electronic databases such as EMBASE, Google Scholar, PubMed, Web of Science, ResearchGate, Cochrane Library, and Science Direct were searched for articles and grey literature. All relevant studies found until our search period of May 24, 2023 were included. The Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of the included studies. The data were extracted in Microsoft Excel. The STATA version 14 software was used to conduct the meta-analysis. I 2 and Cochran's Q test were employed to assess the presence of heterogeneity between studies. Due to the presence of heterogeneity, a random effect model was used. The publication bias was assessed using the symmetry of the funnel plot and Egger's test statistics. Moreover, subgroup analysis, and sensitivity analysis were also done., Results: A total of nine studies that reported the prevalence of dyslipidemia were included. The overall pooled prevalence of dyslipidemia among HIV-infected patients in Ethiopia was 67.32% (95% CI = 61.68%-72.96%). Furthermore, the overall pooled estimates of dyslipidemia among ART-taking and treatment-naïve HIV-infected patients were 69.74% (95% CI: 63.68-75.8, I 2  = 87.2) and 61.46% (95% CI: 45.40-77.52, I 2  = 90.3), respectively. Based on lipid profile fractionations, the pooled estimates for high total cholesterol (TC) were 39.08% (95% CI: 31.16-46.99), high triglycerides were 38.73% (95% CI: 28.58-48.88), high low density lipoprotein (LDL-c) was 28.40% (95% CI: 17.24-39.56), and low high density lipoprotein (HDL-c) was 39.42% (95% CI: 30.47-48.38)., Conclusion: More than two-thirds of HIV-infected patients experienced dyslipidemia. Therefore, it's critical to regularly evaluate lipid alterations in HIV-infected patients in order to prevent the onset of atherosclerosis and other cardiovascular problems., (© 2023.

Background: Genetic and genomic research is revolutionizing precision medicine; however, addressing ethical and cultural aspects is crucial to ensure ethical conduct and respect for community values and beliefs. This study explored the beliefs, perceptions and concerns of the Aari community in South Ethiopia regarding genetic concepts, hereditary diseases and ethical research practices related to sample collection, storage and sharing., Methods: In-depth interviews and focus group discussions were conducted with community elders, health officials, tuberculosis patients and apparently healthy individuals. Data were thematically analysed using MAXQDA software., Results: Participants identified diseases such as podoconiosis, leprosy, goitre and epilepsy as hereditary and perceived some as 'curses' due to generational impact and social stigma. Disease susceptibility was attributed to divine intervention or factors such as malnutrition and sanitation. Although hereditary diseases were considered unavoidable, in some cases environmental factors were acknowledged. Participants shared personal examples to demonstrate inheritance concepts. Blood held cultural significance, and concerns about its potential misuse resulted in scepticism towards giving samples., Conclusions: This study emphasizes the significance of comprehending local beliefs and perceptions and stresses the need to establish effective communication, build trust and address underlying causes of hesitancy to improve recruitment and ensure ethical conduct., (© The Author(s) 2023.

Introduction: Pulmonary tuberculosis (TB) is an infectious disease with high incidence in low-income countries (LICs); it remains one of the infectious diseases with the highest mortality in the world, especially in LICs. It is crucial to recognise and diagnose TB as soon as possible, but microbiological tests on sputum are not always sensitive enough. New methods for an early diagnosis of TB are needed. In this study, we will investigate the role of two different tests to detect TB in Ethiopia (where the prevalence of TB is high): molecular search for TB in stool samples with Xpert assay and detection of pulmonary TB signs on chest X-rays with CAD4TB technology., Methods and Analysis: A prospective diagnostic test accuracy study during TB active contact investigation will be conducted. In the referral hospital in Southwest Shoa Zone, Oromia Region, Ethiopia, patients with pulmonary TB and a sputum sample positive for Mycobacterium tuberculosis and household contacts of at least 4 years of age will be enrolled, with a target sample size of 231 patients. Trained staff will label household contacts as 'possible TB' cases or not according to their symptoms; when TB is possible, a stool Xpert and computer-aided detection on chest X-ray will be performed, alongside standard diagnostic methods, assessing the diagnostic accuracy of CAD4TB compared with Xpert MTB/RIF during TB contact investigation and the accuracy of stool Xpert compared with sputum Xpert., Ethics and Dissemination: This study has been approved by the Oromia Health Bureau Research Ethics Committee (ref no BFO/MBTFH/1-16/100023).

Medical students lack opportunities to have authentic conversations with patients with cancer in busy hospitals. An improved understanding of what such communication might look like may provide a framework for end-of-life curricula. The authors performed thematic analysis using written correspondence between patient and student participants in the University of California, San Francisco's Firefly Program whose letters discussed death or dying. Four themes emerged: (1) turmoil, (2) grief, (3) making peace, and (4) past, present, and future. Medical students expressed a fifth theme: unmet student expectations. The study provides educators with a unique perspective to help inform curriculum development and patient care., (© 2023.

Background: Asymptomatic urinary tract infection (asymptomatic bacteriuria and asymptomatic candiduria) may not be routinely detected in sexually active non-pregnant female population at the initial and reversible stages. This is mainly due to the fact that most women may not feel compelled to seek medical attention., Objectives: The aim of this study was to determine the prevalence, and factors associated with urinary tract infection (UTI), and antibiogram of the uropathogen isolates among asymptomatic female college students., Methods: An institutional-based cross-sectional study was conducted at selected colleges in Dessie from January 2021-March 2021. A total of 422 reproductive age (15 to 49 years) non-pregnant female students were included. Socio-demographic and clinical characteristics data were collected using structured questionnaires. Ten mLs of freshly voided mid-stream urine specimen was collected, transported and processed according to the standard operating procedures. Data were coded and entered for statistical analysis using SPSS version 22.0. Descriptive statistics, bivariate and multivariate logistic regression analysis were performed and p-values <0.05 with the corresponding 95% confidence interval (CI) were considered statistically significant., Result: The overall prevalence of UTI was 24.6%. The prevalence of asymptomatic UTI bacteriuria and candiduria was 57 (13.5%) and 47 (11.1%), respectively. The predominant uropathogens were Staphylococcus saprophyticus 24 (23.1%), followed by Candida tropicalis 23 (22.1%), Candida albican 10 (9.6%), Candida krusei 9 (8.7%) and Escherichia coli 8 (7.7%). Gram negative bacterial isolates showed a higher level of resistance to amoxicillin-clavulanic acid 24 (92.3%). Gram positive bacterial uropathogens showed high level of resistance to penicillin 28 (96.6%) and trimethoprim-sulfamethoxazole 23 (79.3%). Gram positive bacterial isolates were sensitive to norfloxacin, clindamycin, and ciprofloxacin, accounting for 24 (82.7%), 20 (69.0%), and 19 (65.5%), respectively. Multidrug resistance was seen in 50 (87.7%) of bacterial uropathogens. Factors identified for acquisition of UTI were frequency of sexual intercourse (≥3 per week) (AOR = 7.91, 95% CI: (2.92, 21.42), and genital area washing habit (during defecation (AOR = 5.91, 95%CI: (1.86, 18.81) and every morning (AOR = 6.13, 95%CI: (1.60, 23.45))., Conclusion: A significant prevalence of uropathogens, and high resistance of bacterial isolates to the commonly prescribed drugs were detected. Therefore, routine UTI screening, regular health education on the risk of asymptomatic infectious diseases for reproductive age group females, and antimicrobial susceptibility testing should be practiced to avoid the progression of an asymptomatic infection into a symptomatic UTI., Competing Interests: no.

Growth curve analysis can help to optimize the management, determine nutritional requirements, predict the weight of animals at a specific age, and to select highly productive animals. Therefore, this study aimed to find the best-fitted nonlinear functions to provide a specific shape of the growth curve from birth to yearling age in different generations of Boer x Central Highland goats. Gompertz, Logistic, Brody, Von Bertalanffy, Monomolecular, Negative exponential, and Richards models were evaluated to quantify their ability to describe the biological growth curve. Root mean square error (RMSE), Bayesian information criterion (BIC), adjusted coefficient of determination (AdjR2), and Akaike's information criterion (AIC) were used to evaluate the goodness of fit and flexibility of the models. Data were analyzed using the nonlinear regression procedure of SAS. High AdjR2 and lower AIC, BIC, and RMSE values are indicators of best-fitted model. The best-fitting model for the first filial generation (F1), second filial generation (F2), and male goats' growth data was Brody function, whereas the Richards model, followed by Brody, best described the growth of third filial generation (F3) and female goats. The values of parameter A (asymptotic weight) for F1, F2, F3, female, and male goats based on the Brody model were 30.5±1.32, 28.2±1.38, 24.4±1.04, 27.8±0.94, and 29.8±1.32 kg for F1, F2, F3, female, and male goats, respectively. As per the best-fitted growth function, the asymptotic weight tended to reduce when the filial generation increased. The asymptotic weight for male goats was higher than for female goats. F1 had a slightly small value of parameter K, followed by F2 and F3. Both males and females had similar maturity rates. Based on the Brody function, the correlation between maturation rate and mature weight was high (-0.98, P<0.001). The correlation estimates for A-B and B-K were 0.27 and -0.15, respectively. Brody was best fitted for most goat categories, although Richards, followed by Brody, was best fitted for female and F3 goats. Besides, Brody could be better than Richards due to the ease of interpretation, convergence, and applicability for a small sample size. Therefore, the Brody function can predict the mature body weight, maturation rate, and growth rate of Boer x Central Highland goats and be used to formulate breeding and management strategies for profitable goat farming., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Tesema et al.

Additive genetic and non-additive parameters for reproductive traits of Boer x Central Highland goats were estimated. Pedigree and performance records comprised of Central Highland and their crosses with Boer goats were collected from 2009 to 2018 in the Sirinka Agricultural Research Center sheep and goat breeding station. Least-squares means for genotypes were obtained using a general linear model procedure in SAS. To estimate crossbreeding parameters, breed additive, heterotic, and recombination effects were fitted as fixed covariates instead of genotypes. Variance, heritability, and repeatability estimates were estimated through the AI-REML algorithm using WOMBAT software. Genotype did not significantly (P>0.05) influence most of the reproductive traits studied except for gestation length. The additive effect for litter size at birth (LSB), total litter birth weight (LBW), total litter weaning weight (LWW), litter size at weaning (LSW), and gestation length (GL) was estimated to be -0.004 kid, 0.08 kg, -3.18 kg, -0.54 kid, and 3.69 days, respectively. The contribution of heterosis to LSB, LWW, and GL of crossbred goats was negative, while the estimates for LBW and LSW were positive. However, Boer goats' heterosis effect and direct additive contribution to reproductive traits were insignificant (P>0.05) except for LSW. The recombination effect was negligible and not significant (P>0.05) for all traits examined. The direct heritability estimate for LSB, LWB, LWW, LSW, and GL were 0.050, 0.098, 0.086, 0.018, and 0.00, respectively. The repeatability estimates for LSB, LWB, LWW, LSW, and GL were 0.149, 0.116, 0.099, 0.086, and 0.061, respectively. The result indicates that improvement in reproductive traits would not be expected by crossing Boer with Central Highland goats. In addition, heritability estimates indicate that the improvement of reproductive traits through selection will be small, and the repeatability estimates indicate that multiple records have to be used to make a decision of culling or selection., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Tesema et al.

Background and Aims: Intestinal parasites affect the tuberculosis disease outcome by shifting the cell-mediated to humoral immune response and host immune system suppression. However, Mycobacterium tuberculosis (MTB) infection favors the immune escape of parasites. Hence, exploring the rate of intestinal parasitic coinfection with pulmonary tuberculosis (PTB) and its predisposing factors to take better preventive, control, and management measures., Methods: A facility-based cross-sectional study was conducted from September to December 2020 at five health institutions in Hawassa city. A total of 214 PTB patients were diagnosed using the GeneXpert assay and enrolled in this study. Demographic, clinical, and risk factors data were collected using a structured questionnaire. Stool samples were collected using a clean, labeled, and leak-proof stool cup. Stool samples were examined using direct saline microscopy and the formal-ether concentration technique. The data were entered and coded in SPSS software for analysis. Bivariate and multivariate logistic regression were employed to identify the associated risk factors. A p -value less than  0.05 was considered statistically significant., Results: The overall rate of intestinal parasitic-MTB coinfection was 36.9%. The most dominant intestinal parasite was Gardia lamblia (17.8%, 38), followed by Entamoeba histolytica / dispar (9.3%, 20). Intestinal parasitosis coinfection of PTB was associated with being rural resident (adjusted odds ratio [AOR] = 2.42; 95% confidence interval [CI]: 1.23-4.8), not washing of fruits and vegetables before eating [AOR = 4.14; 95% CI: 1.92-9], being at the early stage of anti-TB treatment [AOR = 3; 95% CI: 1.5-6.3] and presence of chronic diseases [AOR = 7; 95% CI: 3.4-14]., Conclusion: The burden of intestinal parasites-MTB coinfection was high. Those who wash fruits and vegetables before eating should be encouraged, early treatment of PTB patients and avoiding the practice of open-field defecation, especially in rural communities, is necessary. The dual effect of coinfection on disease severity and treatment success needs further cohort study., Competing Interests: The authors declare no conflict of interest., (© 2023 The Authors.

Background: COVID-19 is a rapidly emerging global health threat and economic disaster. The epidemiology and outcomes of COVID-19 patients in Ethiopia are scarce. Thus, the present study aimed to assess clinical profiles, epidemiological characteristics, and treatment outcomes of patients with COVID-19 and to identify determinants of the disease outcome among COVID-19 patients in North-eastern Ethiopia., Methods: A retrospective observational cohort study was conducted in North-eastern Ethiopia, from May 2020 to Jan 2022 on a total of 364 SARS-COV-2 infected patients. Demographic and clinical data were abstracted from the medical records of patients. Bivariable and multivariable analyses were conducted to determine the factors associated with the mortality of COVID-19 patients and variables with a P-value < 0.05 were considered statistically significant., Result: Among 364 COVID-19 patients included in this study, two-thirds (68.1%) were males with a median age of 34 years. The majority; 42.9% & 33.0% respectively cases were detected at the health facility and community level surveillance. Furthermore, 6.6% of patients had pre-existing comorbidities of which diabetes mellitus (23.1%) and hypertension (15.3%) had the highest frequency. The symptomatic rate of COVID-19 patients was 30.5%. The most common clinical presentations were cough (26.9%), fever (26.1%), and shortness of breath (15.2%). Moreover, the mortality rate of COVID-19 patients was 4.1% which was independently predicted by a history of underlining co-morbidity (AHR:6.09; 95%CI:1.299-28.56; P = 0.022) and a history of severe or critical conditions (AHR 11.8; 95%CI:4.89-28.83; P = 0.003)., Conclusion: Severe or critical acute COVID-19 and underlining comorbidities are associated with higher mortality. Therefore, critical follow-up and management should be given to patients with underlying diseases is required., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Gedefie et al.

Background: Antimicrobial resistance has remained global public health threat. Carriage with drug-resistant bacterial pathogens, particularly beta-lactamase and carbapenemase-producing Enterobacteriaceae is among the most concerning. The purpose of this study was to look into the magnitude, antimicrobial resistance patterns, and associated risk factors among hospitalized patients., Methods: A facility-based cross-sectional study was conducted on 383 hospitalized patients at Debre Tabor Comprehensive Specialized Hospital between September 2022 and May 2023. A pre-tested structured questionnaire was used to collect sociodemographic and clinical data. The data on the etiologic agent was collected using standard bacteriological techniques. Briefly, stool specimens were collected aseptically into sterile, leak-proof stool cups. The stool sample was inoculated onto MacConkey agar and incubated aerobically at 37 °C for 24 h. The species isolation and antimicrobial resistance patterns were then performed adhering to bacteriological procedures. In the analysis, a p-value of <0.05 was considered statistically significant., Results: There were 383 study participants, and men made up the majority (55.6%). The study participants' mean age was 33 ± 18 years. Three hundred and seventy-seven (88%) of the study's participants had no previous history of antibiotic use. There were 102 (26.6%) and 21 (5.5%) cases of gastrointestinal carriage caused by Enterobacteriaceae that produce beta-lactamase and carbapenemase, respectively. In total, 175 isolates of Enterobacteriaceae were detected. E. coli (n = 89) and K. pneumoniae (n = 51) were the most frequently recovered. In this study, 46 (79.3%) and 8 (13.8%) isolates of E. coli that produce beta-lactamase were resistant to ampicillin and amoxicillin/clavulanic acid, respectively. Furthermore, participants who had previously used antibiotics experienced a two-fold increase in exposure to gastrointestinal tract carriage by carbapenemase-producing Enterobacteriaceae [AOR, 95% CI (2.01, 1.06-2.98), p = 0.001]., Conclusions: The emergence of drug-resistant pathogens is a growing concern. An increase in the prevalence of drug-resistant infections in hospitalized patients is warranting further investigation., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Introduction: The persistence of tuberculosis (TB) infection in some patients after treatment has highlighted the importance of drug susceptibility testing (DST). This study aimed to determine the drug susceptibility patterns of Mycobacterium tuberculosis (M. tuberculosis) isolates from pulmonary TB (PTB) patients in Central and Southern Ethiopia., Methods: A health institution-based cross-sectional study was conducted between July 2021 and April 2022. Sputum samples were collected from newly diagnosed smear microscopy and/or Xpert MTB/RIF-positive PTB patients. The samples were processed and cultivated in Lowenstein-Jensen (LJ) pyruvate and glycerol medium. M. tuberculosis isolates were identified using polymerase chain reaction (PCR) based region of difference 9 (RD9) deletion typing. Phenotypic DST patterns of the isolates were characterized using the BACTEC MGIT™ 960 instrument with SIRE kit. Isoniazid (INH) and Rifampicin (RIF) resistant M. tuberculosis isolates were identified using the GenoType® MTBDRplus assay., Results: Sputum samples were collected from 350 PTB patients, 315 (90%) of which were culture-positive, and phenotypic and genotypic DST were determined for 266 and 261 isolates, respectively. Due to invalid results and missing data, 6% (16/266) of the isolates were excluded, while 94% (250/266) were included in the paired analysis. According to the findings, 14.4% (36/250) of the isolates tested positive for resistance to at least one anti-TB drug. Gene mutations were observed only in the rpoB and katG gene loci, indicating RIF and high-level INH resistance. The GenoType® MTBDRplus assay has a sensitivity of 42% and a specificity of 100% in detecting INH-resistant M. tuberculosis isolates, with a kappa value of 0.56 (95%CI: 0.36-0.76) compared to the BACTEC MGIT™ DST. The overall discordance between the two methods was 5.6% (14/250) for INH alone and 0% for RIF resistance and MDR-TB (resistance to both INH and RIF) detection., Conclusion: This study reveals a higher prevalence of phenotypic and genotypic discordant INH-resistant M. tuberculosis isolates in the study area. The use of whole-genome sequencing (WGS) is essential for gaining a comprehensive understanding of these discrepancies within INH-resistant M. tuberculosis strains., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Tilahun et al.

Introduction: Vancomycin-resistant Staphylococcus aureus, identified as a "high priority antibiotic-resistant pathogen" by the World Health Organization, poses a significant threat to human health. This systematic review and meta-analysis aimed to estimate the pooled prevalence of vancomycin-resistant Staphylococcus aureus in Ethiopia., Methods: This systematic review and meta-analysis was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that reported VRSA prevalence due to infection or carriage from human clinical specimens were extensively searched in bibliographic databases and grey literatures using entry terms and combination key words. Electronic databases like PubMed, Google Scholar, Wiley Online Library, African Journal Online, Scopus, Science Direct, Embase, and ResearchGate were used to find relevant articles. In addition, the Joanna Briggs Institute quality appraisal tool was used to assess the quality of the included studies. Stata version 14 software was used for statistical analysis. Forest plots using the random-effect model were used to compute the overall pooled prevalence of VRSA and for the subgroup analysis. Heterogeneity was assessed using Cochrane chi-square (I 2 ) statistics. After publication bias was assessed using a funnel plot and Egger's test, trim & fill analysis was carried out. Furthermore, sensitivity analysis was done to assess the impact of a single study on pooled effect size., Results: Of the 735 studies identified, 31 studies that fulfilled the eligibility criteria were included for meta-analysis consisted of 14,966 study participants and 2,348 S. aureus isolates. The overall pooled prevalence of VRSA was 14.52% (95% CI: 11.59, 17.44). Significantly high level of heterogeneity was observed among studies (I 2  = 93.0%, p < 0.001). The region-based subgroup analysis depicted highest pooled prevalence of 47.74% (95% CI: 17.79, 77.69) in Sidama region, followed by 14.82% (95% CI: 8.68, 19.88) in Amhara region, while Oromia region had the least pooled prevalence 8.07% (95% CI: 4.09, 12.06). The subgroup analysis based on AST methods depicted a significant variation in pooled prevalence of VRSA (6.3% (95% CI: 3.14, 9.43) for MIC-based methods, and 18.4% (95% CI: 14.03, 22.79) for disk diffusion AST method) which clearly showed that disk diffusion AST method overestimates the pooled VRSA prevalence. The total number of S. aureus isolates was found to be the responsible variable for the existence of heterogeneity among studies (p = 0.033)., Conclusion: This study showed an alarmingly high pooled prevalence of VRSA necessitating routine screening, appropriate antibiotic usage, and robust infection prevention measures to manage MRSA infections and control the emergence of drug resistance. Furthermore, mainly attributable to the overestimation of VRSA burden while using disk diffusion method, there is an urgent need to improve the methods to determine vancomycin resistance in Ethiopia and incorporate MIC-based VRSA detection methods in routine clinical laboratory tests, and efforts should be directed at improving it nationally., Trial Registration: PROSPERO registration identification number: CRD42023422043., (© 2023.

Objective: This study was aimed to determine the 5-year trend of malaria positivity rate in Ziquala district, Northeast Ethiopia., Methods: Review of blood film reports from health institutions' laboratory record books using predesigned checklists was done as part of an institution-based retrospective study to assess the 5-year (2016/2017-2020/2021) trend of malaria. To display data and analyse patterns in the trend of malaria over the course of years, months and seasons, descriptive statistics were used. The results of the data analysis were displayed in tables and figures using SPSS V.26.0. P values under 0.05 were considered as statistically significant for all comparisons., Results: A total of 46 365 blood films from malaria suspected individuals were diagnosed using microscopy over the last 5 years. Of the diagnosed individuals, 14 429 (31.1%) were confirmed positive for Plasmodium infection. Plasmodium falciparum (59.7%) and Plasmodium vivax (37.0%) were the dominant species. The positivity rate of mixed infection ( P. falciparum and P. vivax ) was 3.3%. The maximum (3598; 29.6%) and minimum (2085; 29.1%) number of cases were reported in 2019/2020 and 2020/2021, respectively. Of the total cases, 9206 (63.8%) were in males. Moreover, the highest malaria positivity rate was observed in the age group of 15-45 (4040; 28.0%). Among the six health facilities, Ziquala district hospital had the highest malaria positivity rate (35.8%), followed by Tsitsika health centre (27.3%) and Mishra health centre (14.2%)., Conclusion: With P. falciparum being the most common species, malaria remains a severe public health threat in the district. Therefore, the district health office and other concerned bodies should strengthen and implement evidence-based malaria prevention and control measures., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Hyperuricemia increases morbidity and mortality in type 2 diabetic individuals. It is linked to the expansion of diabetes and cardiovascular diseases indicators, as well as being a significant predictor of coronary artery disease. It also leads to a poor prognosis and increment of diabetic complications including diabetic neuropathy, retinopathy, and nephropathy. Therefore, this systematic review and meta-analysis was aimed to determine the pooled prevalence of hyperuricemia among type 2 diabetes mellitus patients in Africa., Methods: We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. To identify relevant articles, we searched electronic databases such as PubMed, Google Scholar, African Journal Online, Science Direct, Embase, ResearchGate, Scopus, and Web of Sciences. The quality of the included studies was assessed using the Newcastle-Ottawa Quality Assessment Scale. Statistical analysis was performed using Stata 14.0 software. To evaluate heterogeneity, we utilized Cochran's Q test and I 2 statistics. Publication bias was assessed through the examination of a funnel plot and Egger's test. The pooled prevalence was estimated using a random effect model. Furthermore, sub-group and sensitivity analyses were conducted., Results: The overall pooled prevalence of hyperuricemia among type 2 diabetic patients in Africa was 27.28% (95% CI: 23.07, 31.49). The prevalence was highest in Central Africa 33.72% (95% CI: 23.49, 43.95), and lowest in North Africa 24.72% (95% CI: 14.38, 35.07). Regarding sex, the pooled prevalence of hyperuricemia among female and male type 2 diabetic patients was 28.02% (95% CI: 22.92, 33.48) and 28.20% (95% CI: 22.92, 33.48), respectively., Conclusion: This systematic review and meta-analysis showed a high prevalence of hyperuricemia among type 2 diabetic patients. So, regular screening and diagnosis of hyperuricemia required for preventing its pathological effects and contribution to chronic complications of diabetes., Systematic Review Registration: PROSPERO (2022: CRD42022331279)., (© 2023.

Background: Microalbuminuria (MAU) is considered the earliest sign of diabetic nephropathy among diabetes patients. In order to effectively manage diabetic nephropathy and its consequences early, detection of microalbuminuria as soon as possible, especially for diabetes patients, is critical. Therefore, the present study aimed to determine the pooled prevalence of microalbuminuria among diabetes patients in Africa., Methods: Electronic databases such as Google Scholar, PubMed, African Journals Online, Web of Science, Cochrane Library, EMBASE, and ResearchGate were searched for articles and grey literature. The STATA version 14 software was used to conduct the meta-analysis. I 2 and Cochran's Q test were employed to assess the presence of heterogeneity between studies. Due to the presence of heterogeneity, a random effect model was used. The publication bias was assessed using the symmetry of the funnel plot and Egger's test statistics. Moreover, subgroup analysis, trim and fill analysis, and sensitivity analysis were also done., Results: The overall pooled prevalence of microalbuminuria among diabetes patients in Africa was 37.11% (95% CI 31.27-42.95). Substantial heterogeneity was observed between studies, with I 2 values of 94.7%. Moreover, this meta-analysis showed that the pooled estimate of microalbuminuria among type 1 and type 2 diabetes patients was 35.34% (95% CI: 23.89-46.80, I 2 =94.2), and 40.24% (95% CI: 32.0-48.47, I 2 =94.9) respectively. MAU, on the other hand, was more common in people with diabetes for more than 5 years 38.73% (95% CI: 29.34-48.13) than in people with diabetes for less than 5 years 31.48% (95% CI: 18.73-44.23)., Conclusion: This systematic review and meta-analysis found a high prevalence of microalbuminuria among diabetes patients. As a result, early detection of microalbuminuria is critical for preventing and treating microvascular complications such as diabetic nephropathy and the onset of end-stage renal disease., Competing Interests: The authors declare that they have no potential competing interests in this work., (© 2023 Mohammed et al.)

Background: The persistent efforts of HIV/AIDS epidemiology remain one of the world's most important community health threats. To avoid becoming an epidemic, UNAIDS has set three 90% fast-track targets for 2020, and Ethiopia has also changed its implementation since 2015. However, the achievement targets in the Amhara region have yet to be evaluated at the end of the programme period., Objective: The aim of this study was to assess the Trends of HIV Infection and Antiretroviral Treatment outcome in Eastern Amhara Regional from 2015 to 2021, Northeast Ethiopia., Methods: A retrospective study was conducted by reviewing the District Health Information System from 2015 to 2021. The collected data includes the trend of HIV testing services, the trend of HIV positivity, the yield of HIV testing approaches, the number of HIV positive patients linked to HIV care and treatment or access to lifelong antiretroviral therapy, viral load testing coverage, and viral suppression. A descriptive statistic and trend analysis were computed., Results: A total of 145,639 people accessed antiretroviral therapy. The trend of HIV test positivity has been declining since 2015, peaking at 0.76% in 2015 and declining to 0.60% in 2020. A high level of positivity was reported in volunteer counselling and testing as compared with provider-initiated testing and counselling services. Following an HIV positive, there was an increase in linkage to HIV care and treatment. High suppression rates of viral load indicate testing coverage grew over time. The viral load monitoring coverage was 70% in 2021, with a viral suppression rate of 94%., Conclusion and Recommendations: The trend in achievement in the first 90s was not consistent with predefined goals (90%). On the other hand, there was good achievement in the second and third goals. Hence, intensified case-finding approaches to HIV testing should be strengthened., Competing Interests: The authors state that they have no conflicts of interest in this research work., (© 2023 Addisu et al.)

Background and Aims: Malaria elimination programs have also encountered numerous challenges, such as widespread asymptomatic carriers in endemic areas, which should be taken into account in malaria-control programs for effective transmission interruption. The purpose of this research was to determine the prevalence of symptomatic and asymptomatic malaria infections and associated factors, in pastoral communities., Methods: A community-based cross-sectional study was conducted among selected districts in the Waghemra Zone, Northeast Ethiopia, from September to December 2022. A structured questionnaire was employed to collect sociodemographic data and associated risk factors. Plasmodium species were detected using light microscopy and a rapid diagnostic test. Data entry and analysis were carried out using SPSS version 26 software. The association between dependent and independent variables was explored by using multivariable logistic regression analyses. A statistically significant association was declared at a p -value of <0.05., Results: The overall prevalence of malaria was 21.2% (134/633), with the predominant Plasmodium falciparum infections accounting for 67.8% (87/134). Among asymptomatic participants, 7.5% (34/451) and 10.2% (46/451) were diagnosed by rapid diagnostic test and light microscopy, respectively. On the other hand, the prevalence of symptomatic malaria was 44.5% (81/182) and 48.4% (88/182) as diagnosed by rapid diagnostic test and light microscopy, respectively. The presence of stagnant water near the houses, the utilization of insecticide-treated mosquito nets, the number of insecticide-treated mosquito nets, and outdoor stays at night were all positively linked with the prevalence of malaria., Conclusions: The overall prevalence estimate for symptomatic and asymptomatic malaria was high. Malaria is still a public health problem in the study area. Malaria infection was associated with the presence of stagnant water near the houses, the utilization of insecticide-treated mosquito nets, the number of insecticide-treated mosquito nets, and outdoor stays at night. Improved access to all malaria interventions is needed to interrupt the transmission at the community level., Competing Interests: The authors declare no conflict of interest., (© 2023 The Authors.

Background and Aim: Toxoplasmosis is the most widespread zoonotic disease that affects one-third of the world's population, and imposes a major public health problem worldwide. This study aimed to assess the prevalence of toxoplasmosis among patients with neuropsychiatric patients., Methods: Electronic databases PubMed, Google Scholar, Web of Science, Research Gate, and Scopus were thoroughly searched from February to March 2022 to identify all relevant studies. The quality of studies was evaluated using the Newcastle-Ottawa quality scale for case-control and cross-sectional studies. Statistical analysis was done using STATA version 12 software. A random effect model was used to compute the global pooled seroprevalence of Toxoplasma gondii infection. Heterogeneity was quantified by using I 2 value. Subgroup analysis was done, and publication bias was assessed using a funnel plot and Egger's test., Result: Of 1250 studies, 49 containing 21,093 participants and conducted in 18 countries were included. The global pooled seroprevalence of T. gondii IgG antibody was 38.27% (95% CI: 32.04-44.9) among neuropsychiatric patients and 25.31% (95% CI: 21.53-29.08) in healthy controls with substantial heterogeneity of 98.3%. The prevalence of T. gondii IgG antibody was higher in males (17.52%) than in females (12.35%) neuropsychiatric patients. The highest pooled prevalence of T. gondii IgG antibody was in Europe (57%) followed by Africa (45.25%) and Asia (43%). Time based analysis showed the highest pooled prevalence of T. gondii IgG antibody in 2012-2016 (41.16%).The global pooled seroprevalence T. gondii IgM antibody among neuropsychiatric patients and healthy controls was 6.78% (95% CI: 4.87-8.69) and 3.13% (95% CI: 2.02-4.24), respectively., Conclusion: The pooled prevalence of chronic and acute T. gondii infection among neuropsychiatric patients was 38.27% and 6.78%, respectively. This showed a high burden of toxoplasmosis among neurological and psychiatric patients and urges routine screening of those patients and providing appropriate treatment. It also indicates the need for different stakeholders to develop targeted prevention and control strategies for T. gondii infection., Competing Interests: The authors declare no conflict of interest., (© 2023 The Authors.

Background: Extrapulmonary tuberculosis (EPTB), particularly tubercular lymphadenitis (TBLN), remains to pose a huge public health problem in Ethiopia. A significant number of TBLN patients who completed a full course anti-TB treatment regimen were reported to have enlarged lymph nodes and other TB-like clinical presentations. This could either be from a paradoxical reaction or microbiological relapse, possibly due to mono/multi-drug resistance., Objective: To investigate the rate of mono and multidrug resistance patterns of Mycobacterium tuberculosis as a cause of the observed treatment failures in clinically diagnosed and anti-TB treatment (newly or previously)-initiated LN patients., Methods: A cross-sectional study was conducted on 126 TBLN-suspected and previously treated patients between March and September 2022. Data were analyzed using SPSS (Version 26.0). Descriptive statistics were used to determine the frequency, percentage, sensitivity, specificity, and positive and negative predictive values. The level of agreement was determined using Cohen's kappa and a Chi-square test was used to measure the association between risk factors and laboratory test outcomes. A P -value <0.05 was considered statistically significant., Results: Mycobacterium tuberculosis was confirmed in 28.6% (N=36) of the 126 cases using BACTEC MGIT 960 culture detection method. Approximately, 13% (N=16) of the samples were collected from previously treated TBLN patients, of which 5/16 (31.3%) were multi-drug resistant, 7/16 were drug-sensitive and 4/16 were culture negative. To rule out other non-tuberculous agents, all samples were grown on blood and Mycosel agar plates, and no growth was detected., Conclusion: The emergence of drug resistant (DR) TB seems to not just be limited to pulmonary form but also to TBLN. In this study we observed a considerable number of microbiologically confirmed relapses among previously treated cases, possibly indicating the need for confirmation of drug resistance using rapid molecular methods or phenotypical methods during treatment follow up., Competing Interests: The authors report no conflicts of interest in this work., (© 2023 Atnafu et al.)
