Bacterial contamination of single and multiple-dose parenteral injection vials after opening and antibiotic susceptibility of isolates at Jimma Medical Center, Jimma, Southwest Ethiopia. Infect Prev Pract 2023; 5:100290. [PMID: 37457638 PMCID: PMC10339008 DOI: 10.1016/j.infpip.2023.100290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 05/26/2023] [Indexed: 07/18/2023] Open
Abstract
Background Single- or multiple-dose vials are prone to bacterial contamination after improper handling and can be potential reservoirs of microorganisms that could be transmitted to the patient through the parenteral route. The present study aims to assess the magnitude of the problem and associated factors at Jimma Medical Center (JMC), Jimma, Southwest Ethiopia. Methods A cross-sectional study design was conducted at JMC from July 2021 to October 2021. A total of 384 parental medications and nurse interviews that were administered in 11 wards and 3 intensive care units were included. Samples were processed and identified by conventional bacterial culture methods. Results The overall prevalence of vial contamination due to aerobic bacteria was 21 (5.5%) among multiple-dose vials and none of the single-dose vials. The highest level of contamination (8, 38.1%) was found in the paediatric ward. Pseudomonas aeruginosa and Klebsiella pneumoniae were the most common microorganisms identified vial contamination, 6 cases (28.5%) and 5 cases (23.8%) respectively Multidrug resistance was identified in 95.2% of the isolates, with all Gram-negative isolates showing a multidrug resistance against the tested antibiotics. In multivariate logistic regression analysis, vial contamination was strongly associated with reuse of syringe and/or needle, the environment where medication was handled, and the storage conditions. Conclusion In this study, the prevalence of vial contamination was high. The bacterial isolates from vials were also resistant to commonly prescribed antimicrobial drugs. Healthcare professionals must strictly adhere to basic infection control practices as per standard guidelines to reduce the risk of infection from contaminated vials.

Abstract
Auto-disable (AD) syringes are specifically designed to prevent syringe reuse. However, the notion that specific AD syringe designs may be unsafe due to reuse concerns related to the syringe's activation point has surfaced. We conducted a systematic review for evidence on the association between AD syringe design and syringe reuse, adverse events following immunization (AEFI), or blood borne virus (BBV) transmission. We found no evidence of an association between AD syringe design and unsafe injection practices including syringe reuse, AEFIs, or BBVs. Authors of three records speculated about the possibility of AD syringe reuse through intentionally defeating the disabling mechanism, and one hinted at the possibility of reuse of larger-than-required syringes, but none reported any actual reuse instance. In contrast to AD syringes, standard disposable syringes continue to be reused; therefore, the global health community should expand the use of AD syringes in both immunization and therapeutic context as an essential strategy for curbing BBV transmission.

Abstract
Molecular studies suggest that HIV arose in Africa between 1880 and 1940. During this period, there were campaigns by European colonial governments that involved unsterile injections of large numbers of Africans. That, along with other unsafe therapeutic interventions, may have propelled the evolution of HIV from SIV. Since subtype B in Africa may have been concentrated in white African homosexuals, it is possible that Westerners rather than Haitians introduced the virus to the New World. Amplification of HIV subtype B took place in Haiti, where transmission was facilitated by hazardous medical procedures including plasmapheresis. Representations in the media, however, largely ignore Western contributions to the spread of AIDS. This article focuses on the value of alternative narratives in fostering a balanced view that is less stigmatizing on developing nations.

Abstract
Neglected tropical diseases caused by trypanosomatid parasites are a continuing and escalating problem, which devastate the less economically developed cultures in countries in which they are endemic by impairing both human and animal health. Current drugs for these diseases are regarded as out-of-date and expensive, with unacceptable side-effects and mounting parasite resistance, meaning there is an urgent need for new therapeutics. Natural products have long been a source of potent, structurally diverse bioactive molecules. Herein are reviewed natural products with reported trypanocidal activity, which have been clustered based on core structural similarities, to aid the future discovery of new trypanocidal core motifs with potential routes to synthetically accessible natural product cores suggested.

Abstract
Hepatitis C virus (HCV) infection presents an important, but underappreciated public health problem in Africa. In Côte d'Ivoire, very little is known about the molecular dynamics of HCV infection. Plasma samples (n = 608) from pregnant women collected in 1995 from Côte d'Ivoire were analyzed in this study. Only 18 specimens (∼3%) were found to be HCV PCR-positive. Phylogenetic analysis of the HCV NS5b sequences showed that the HCV variants belong to genotype 1 (HCV1) (n = 12, 67%) and genotype 2 (HCV2) (n = 6, 33%), with a maximum genetic diversity among HCV variants in each genotype being 20.7% and 24.0%, respectively. Although all HCV2 variants were genetically distant from each other, six HCV1 variants formed two tight sub-clusters belonging to HCV1a and HCV1b. Analysis of molecular variance (AMOVA) showed that the genetic structure of HCV isolates from West Africa with Côte d'Ivoire included were significantly different from Central African strains (P = 0.0001). Examination of intra-host viral populations using next-generation sequencing of the HCV HVR1 showed a significant variation in intra-host genetic diversity among infected individuals, with some strains composed of sub-populations as distant from each other as viral populations from different hosts. Collectively, the results indicate a complex HCV evolution in Côte d'Ivoire, similar to the rest of West Africa, and suggest a unique HCV epidemic history in the country.

Abstract
Hepatitis C virus (HCV) is a major health burden infecting 170-210 million people worldwide. Additional 3-4 millions are newly-infected annually. Prevalence of pediatric infection varies from 0.05%-0.36% in the United States and Europe; up to 1.8%-5.8% in some developing countries. The highest prevalence occurs in Egypt, sub-Saharan Africa, Amazon basin and Mongolia. HCV has been present in some populations for several centuries, notably genotypes 1 and 2 in West Africa. Parenteral anti-schistosomal therapy practiced in the 1960s until the early 1980s had spread HCV infection throughout Egypt. Parenteral acquisition of HCV remains a major route for infection among Egyptian children. Insufficient screening of transfusions, unsterilized injection equipment and re-used needles and syringes continue to be major routes of HCV transmission in developing countries, whereas vertical transmission and adolescent high-risk behaviors (e.g., injection drug abuse) are the major routes in developed countries. The risk of vertical transmission from an infected mother to her unborn/newborn infant is approximately 5%. Early stages of HCV infection in children do not lead to marked impairment in the quality of life nor to cognitive, behavioral or emotional dysfunction; however, caregiver stress and family system strain may occur. HCV slowly progresses to serious complications as cirrhosis (1%-2%) and hepatocellular carcinoma (HCC) especially in the presence of risk factors as hemolytic anemias, obesity, treated malignancy, and concomitant human immune deficiency and/or hepatitis B virus co-infection. HCV vaccine remains elusive to date. Understanding the immune mechanisms in patients who successfully cleared the infection is essential for vaccine development. The pediatric standard of care treatment consists of pegylated interferon-α 2a or b plus ribavirin for 24-48 wk. The new oral direct acting antivirals, approved for adults, need further evaluation in children. Sustained virologic response varies depending on the viral load, genotype, duration of infection, degree of aminotransferase elevation, adiposity and single nucleotide polymorphisms of interleukin (IL)-28B locus. The goals of treatment in individual patients are virus eradication, prevention of cirrhosis and HCC, and removing stigmatization; meanwhile the overall goal is decreasing the global burden of HCV. IL-28B polymorphisms have been also associated with spontaneous clearance of vertically acquired HCV infection. The worldwide economic burden of HCV for children, families and countries is estimated to be hundreds of millions of US dollars per year. The United States, alone, is estimated to spend 199-336 million dollars in screening, monitoring and treatment during one decade. The emotional burden of having an HCV infected child in a family is more difficult to estimate.

Abstract
In 2009, an assessment of injection practices in Fumeng County (Liaoning Province) and Wulong County (Chongqing Municipality) (random sample of 29 hospitals, 40 village clinics and 400 villagers) was conducted and the results were compared with a prior 2001 assessment (same area, same WHO assessment tool). In 2009, all facilities in Fumeng and Wulong used new, disposable syringes compared with 34% in both counties in 2001. Moreover, 59% (95% CI 37-80%) and 74% (95% CI 55-94%) of providers in Fumeng and Wulong, respectively, collected used sharps safely compared with 33% (95% CI 20-45%) and 36% (95% CI 20-53%) in 2001. In Fumeng and Wulong, respectively, 5% (95% CI 0-15%) and 50% (95% CI 25-76%) of facilities discarded injection devices in the regular trash compared with 7% (95% CI 2-12%) and 64% (95% CI 47-80%) in 2001. Between 2001 and 2009, the annual average number of injections per person increased from 1.8 to 6.3 (95% CI 4.5-8.1) in Fumeng and was stable [3.4 and 3.1 (95% CI 1.9-4.3)] in Wulong. Overall, between 2001 and 2009, sterilisable injection devices disappeared and disposal practices improved. However, unsafe practices persisted, which should be improved. Use of injections to administer medications may be increasing and must be reduced.

Abstract
After witnessing an episode of poor injection safety in large numbers of children in a rural under-resourced hospital in Uganda, we briefly review our own experience and that of others in investigating HIV infection in children considered unlikely to be through commonly identified routes such as vertical transmission, sexual abuse or blood transfusion. In the majority of cases, parents are HIV uninfected. The cumulative experience suggests that the problem is real, but with relatively low frequency. Vertical transmission is the major route for HIV to children. However, factors such as poor injection safety, undocumented surrogate breast feeding, an HIV-infected adult feeding premasticated food to a weaning toddler, poor hygienic practice in the home and using unsterilised equipment for minor surgical or traditional procedures are of cumulative concern.

Abstract
Background: Unsafe medical injections are a prevalent risk factor for viral hepatitis and HIV in India. Objectives: This review undertakes a cost–benefit assessment of the auto-disable syringe, now being introduced to prevent the spread of hepatitis B virus, hepatitis C virus, and human immunodeficiency virus (HIV). Materials and Methods: The World Health Organization methods for modeling the global burden of disease from unsafe medical injections are reproduced, correcting for the concentrated structure of the HIV epidemic in India. A systematic review of risk factor analyses in India that investigate injection risks is used in the uncertainty analysis. Results: The median population attributable fraction for hepatitis B carriage associated with recent injections is 46%, the median fraction of hepatitis C infections attributed to unsafe medical injections is 38%, and the median fraction of incident HIV infections attributed to medical injections is 12% in India. The modeled incidence of blood-borne viruses suggests that introducing the auto-disable syringe will impose an incremental cost of $46–48 per disability adjusted life year (DALY) averted. The epidemiological evidence suggests that the incremental cost of introducing the auto-disable syringe for all medical injections is between $39 and $79 per DALY averted. Conclusions: The auto-disable syringe is a cost-effective alternative to the reuse of syringes in a country with low prevalence of blood-borne viruses.
