Epidemiology of vancomycin-resistant enterococci in the United Arab Emirates: a retrospective analysis of 12 years of national AMR surveillance data.

Enterococci are usually low pathogenic, but can cause invasive disease under certain circumstances, including urinary tract infections, bacteremia, endocarditis, and meningitis, and are associated with peritonitis and intra-abdominal abscesses. Increasing resistance of enterococci to glycopeptides and fluoroquinolones, and high-level resistance to aminoglycosides is a concern. National antimicrobial resistance (AMR) surveillance data for enterococci from the Middle East and North Africa (MENA) and the Gulf region is scarce. A retrospective 12-year analysis of N = 37,909 non-duplicate diagnostic Enterococcus spp. isolates from the United Arab Emirates (UAE) was conducted. Data was generated by routine patient care during 2010-2021, collected by trained personnel and reported by participating surveillance sites to the UAE National AMR Surveillance program. Data analysis was conducted with WHONET. Enterococcus faecalis was the most commonly reported species (81.5%), followed by Enterococcus faecium (8.5%), and other enterococci species (4.8%). Phenotypically vancomycin-resistant enterococci (VRE) were found in 1.8% of Enterococcus spp. isolates. Prevalence of VRE (%VRE) was highest for E. faecium (8.1%), followed by E. faecalis (0.9%). A significant level of resistance to glycopeptides (%VRE) for these two species has been observed in the majority of observed years [E. faecalis (0-2.2%), 2010: 0%, 2021: 0.6%] and E. faecium (0-14.2%, 2010: 0%, 2021: 5.8%). Resistance to fluoroquinolones was between 17 and 29% (E. faecalis) and was higher for E. faecium (between 42 and 83%). VRE were associated with higher patient mortality (RR: 2.97), admission to intensive care units (RR: 2.25), and increased length of stay (six excess inpatient days per VRE case), as compared to vancomycin-susceptible Enterococcus spp. Published data on Enterococcus infections, in particular VRE-infections, in the UAE and MENA region is scarce. Our data demonstrates that VRE-enterococci are relatively rare in the UAE, however showing an increasing resistance trend for several clinically important antibiotic classes, causing a concern for the treatment of serious infections caused by enterococci. This study also demonstrates that VRE were associated with higher mortality, increased intensive care unit admission rates, and longer hospitalization, thus poorer clinical outcome and higher associated costs in the UAE. We recommend the expansion of current surveillance techniques (e.g., local VRE screening), stricter infection prevention and control strategies, and better stewardship interventions. Further studies on the molecular epidemiology of enterococci are needed.

Investigation of Microbiological, Physiological and Histopathological Changes in Polymicrobial Infection in Old Rats

Background: The aim of this study is to examine the microbiological, clinical, physiological and pathological findings of natural polymicrobial infection developing in a wistar rat colony under long-term observation. Methods: In this study, 70 male Wistar albino rats, 3 years old, raised by conventional methods and housed in a cage environment were used. Thirteen rats with clinical symptoms such as torticollis and rotation were sacrificed for microbiological and histopathological examination after 14 days. For microbiological examination, the rapid diagnostic kit BBL Crystal system was used to identify bacterial agents in tissue and stool samples, and the traditional culture method was used for isolation. Result: As a result of microbiological analysis, the rarely isolated Staphylococcus capitis (S. capitis) was isolated. Different Staphylococcus spp. It has been determined that the species can cause suppurative meningoencephalitis as well as septicemia in the brains of experimental animals., it is thought that polymicrobial infection will be useful for the identification of bacterial agents and infection prevention and treatment strategies.

Epidemiology and molecular typing of multidrug-resistant bacteria in tertiary hospitals and nursing homes in Flanders, Belgium.

This study aimed to map MDRO carriage and potential transmission within and between three Flemish tertiary care hospitals and their neighbouring nursing homes. A cross-sectional MDRO prevalence survey was organized between October 2017 and February 2019. Perianal swabs were cultured for detection of MDRO. Determination of clonal relatedness based on wgMLST allelic profiles was performed. The prevalence of MDRO in Belgian hospitals and NHs is on the rise, compared to previous studies, and transmission in and between institutions is observed. These results re-emphasize the need for a healthcare network-wide infection prevention strategy in which WGS of MDRO strains can be supportive.

Trends in the numbers of SARS-CoV-2 infections among students: a prospective cohort study comparing students in sports boarding schools with students in day schools during early COVID-19 pandemic.

During the first months of the COVID pandemic it emerged that facilities where people gather or live together in cohorts, such as nursing homes or schools, were particularly at high risk for becoming hotspots of virus transmission. German political and health institutions responded with far-reaching interventions and preventive strategies to protect the population from infection with SARS-CoV-2. In this context, it remains unclear whether boarding schools for sports particularly pose a risk of infection to their residents. In a single-center prospective cohort study, numbers of SARS-CoV-2 infections of students in sports boarding schools (n = 11) vs. students attending regular day schools (n = 22) in the region Freiburg/Hochschwarzwald in Germany were investigated over a period from October 2020 to January 2021 via regular virus and antibody screening (German Clinical Trials Register; Study ID: DRKS00021909). In addition, individual and behavioral risk factors for infection were stratified via questionnaire, which provide an indication of cohort specific risk factors for infection and the success of the implementation of hygiene concepts, as well as other infection prevention strategies, within the respective facilities. Regarding SARS-CoV-2 infection numbers, the screening detected no significant group difference between sports boarding schools vs. day schools. The study results provide indications that sports boarding schools did not pose an increased risk of infection, assuming that the facilities prevent virus transmissions with appropriate preventive strategies and hygiene measures. In future pandemic scenarios larger-scale and multicenter studies are necessary to achieve more comprehensive epidemiological data in this field.

Large-scale resurgence of herpangina in Japan, following the easing of COVID-19 measures

ObjectivesThis study examined the rise in herpangina cases and its demographic trends in Japan post-easing of COVID-19 restrictions in the summer of 2023, assessing its potential strain on pediatric healthcare. MethodsWeekly herpangina cases data from the National Institute of Infectious Diseases from 2017 to 2023 were analyzed using difference-in-differences methodology and Poisson regression models, incorporating variables such as time, the COVID-19 pandemic, and the easing of measures. Statistical significance was set at a two-sided P-value of 0.05. ResultsA significant increase in herpangina cases was observed from the 19th to the 27th week of 2023, with a notable shift in age distribution compared to that of pre-pandemic years. Poisson regression analysis revealed a positive correlation between the number of herpangina cases and the easing of infection control measures. There was an increase in other respiratory illnesses, including respiratory syncytial virus, particularly in children aged 3 and above. ConclusionWe found a surge in herpangina cases in Japan after the easing of the COVID-19 restrictions during the summer of 2023, along with a noticeable increase in other respiratory illnesses, emphasizing the potential strain on pediatric healthcare and reinforcing the ongoing significance of implementing general infection prevention strategies.

Impact of Clostridioides difficile infection in heart failure hospitalizations: analysis from the national inpatient sample database

Abstract Background Congestive heart failure (CHF) patients are at greater risk of nosocomial infections such as Clostridioides difficile infection (CDI) due to higher comorbidities, readmission rates, and prolonged hospital stays. Further, hypovolemia and sympathetic drive may aggravate myocardial dysfunction due to demand mismatch and worsen clinical outcomes. Purpose To assess the impact of CDI in congestive heart failure (CHF) hospitalizations nationally in the US. Methods The National Inpatient Sample database from 2016 to 2019 was queried to identify patients with a primary diagnosis of CHF. Subsequently, the sample was stratified based on the presence of CDI as a secondary diagnosis. The adjusted odds ratios (aOR) of in-hospital outcomes were calculated using chi-square statistics in software STAT v.17. Results Of 1,270,414 weighted hospitalizations with CHF, 8275 were diagnosed with CDI (0.65%). On adjusted analysis, patients with CHF and CDI had significantly higher in-hospital mortality (aOR 3.58, 95% CI 3.28-4.51, p<0.001), cardiac arrest (aOR 3.89, 95% CI 2.79-5.41, p<0.001), AMI (aOR 1.37, 95% CI 1.08-, p=0.007), MCS (aOR 5.16, 95% CI 3.91-6.8, p<0.001), stroke (aOR 1.85, 95% CI 1.09-3.14, p=0.022) and MACE (aOR 2.54, 95% CI 2.21-2.91, p<0.001), (Figure 1). Additionally, HF patients with CDI are associated with longer lengths of stay (12±16 vs. 5±6 ) and adjusted total charge ($133,045±291,290 vs. $51,919±133,303) compared to HF patients without CDI (Table 1). Conclusions CDI in CHF hospitalizations have adverse in-hospital outcomes with higher rates of in-hospital mortality, AMI, stroke, and MACE. This highlights the importance of early detection and aggressive infection prevention strategies in this high-risk population.Figure 1Table 1

Unveiling the Symbiosis of Environmental Sustainability and Infection Control in Health Care Settings: A Systematic Review

This systematic review explores the intricate relationship between environmental sustainability and infection control in healthcare. A comprehensive examination of twelve selected studies reveals key themes, including the pivotal role of leadership in motivating sustainable practices within healthcare facilities and the integration of sustainable design strategies for effective infection prevention and control. The review emphasizes the significance of strong leadership in driving a culture of environmental responsibility, fostering staff engagement, and ensuring the success of sustainability initiatives. Sustainable design strategies, such as energy-efficient building practices and eco-friendly materials, emerge as essential components of both environmental sustainability and infection control. By creating synergy between these objectives, healthcare facilities can simultaneously reduce their environmental footprint and enhance patient safety. This study underscores the importance of leadership commitment and sustainable design in shaping the future of healthcare toward a more environmentally responsible and infection-resistant paradigm.

Prevention strategies for urinary tract infection

One of the most predominant bacterial diseases is urinary parcel contaminations, which are regularly treated with anti-microbial and normally influence kids and ladies. Later on, a worldwide danger to the treatment of contaminations originates from the disturbing ascent in anti-infection opposition. There are maybe five techniques for forestalling repetitive urinary plot diseases (UTIs) that are either presently suggested or being scrutinized: normal peptides as well as anti-infection agents; supplement thick food varieties; vaccines; probiotics; what's more, different things, for example, staying away from spermicides and keeping up with great hygiene. Any reasonable person would agree that numerous ladies are evaluating elective medicines to help their safe frameworks, like drinking cranberry squeeze or taking homegrown supplements. The improvement of immunizations for creatures other than Escherichia coli is still quite far from being utilized by people. There are sure counteraction systems for the anticipation of urinary plot diseases in the two ladies and children.

Implementation of a Colorectal Surgical Site Infection Prevention Bundle and Checklist: A Quality Improvement Project.

After noting an elevated surgical site infection rate in 2019 associated with colorectal surgeries, leaders at two Central Virginia health system hospitals convened an interdisciplinary team to audit current practices and research infection prevention strategies. After identifying a lack of standardization in care processes for colorectal surgery patients and reviewing the literature on colorectal bundles, the team created a bundle focusing on the use of antibiotics, chlorhexidine gluconate wipes or baths, separate closing instrument trays, nasal decolonization, bowel preparation, and maintaining patient normothermia. After synthesis and stakeholder input, the team implemented the colorectal bundle along with a checklist for all users to complete to ensure compliance and standardization of practice and for auditing purposes. Implementation results were positive: the total number of colorectal infections decreased from nine in 2020 to three in 2021. Education was critical to securing staff member engagement for successful implementation of and compliance with the bundle.

Role of the contaminated environment in transmission of multidrug-resistant organisms in nursing homes and infection prevention

With aging of the population in the United States, there are more people in long-term care facilities than in hospitals. Nursing home residents have a high prevalence of colonization with multidrug-resistant organisms (MDROs). A shared environment with vulnerable patients can facilitate intra- and inter-facility transmission of MDROs. The aim of this paper is to examine the role of the nursing home environment in MDRO transmission and provide infection prevention strategies. We searched the published literature and reviewed selected articles on contamination, transmission, and infection associated with the nursing home environment. Nursing home residents were frequently colonized with MDROs, leading to contamination of the surrounding environment with the same pathogen. Surface contamination with MDROs was common in nursing home patient rooms, and to a substantial but lesser frequency in common rooms. Shared rooms were a risk factor for MDRO transmission between patients. Since outbreaks and infections via the environmental contamination cause substantial burden of morbidity and mortality in the nursing home residents, it is essential for healthcare personnel to recognize the role of the nursing home environment in infection transmission and adhere to the current infection prevention guidelines for cleaning and disinfection of environmental surfaces.

Putting blood donors at the heart infectious disease surveillance

Abstract Issue The emergence of SARS-CoV-2 brought with it an urgent need to generate accurate and real-time surveillance data. The Irish Blood Transfusion Service (IBTS), along with many blood establishments worldwide undertook SARS-CoV-2 serosurveillance studies using residual blood donor serum. This response highlighted the role that blood donors can play in informing public health policy. Description In September 2020 the IBTS undertook a SARS-CoV-2 seroprevalence study using blood donor specimens to track the ‘first-wave’ of the COVID-19 pandemic in Ireland. We utilised our operational capacity for sample collection and screening to quickly generate seroprevalence data. In 2021, the newly established National Serosurveillance Program (NSP) in Ireland invited the IBTS to collaborate on a SARS-CoV-2 serosurveillance study in blood donors which has continued into 2023. Results This response has led to an enhanced relationship between the IBTS and public health in Ireland and has highlighted a possible future role for the IBTS in providing ‘real-time’ seroprevalence data to policy-makers. This data can be used to inform decision-making in relation to infection prevention and control strategies including vaccination policy. Lessons This practice highlights the role that blood establishments can play in informing public health policy and indicates that this role could be expanded in the future in the cases of both emerging infections and vaccine preventable diseases. Blood donor studies offer a unique opportunity to screen healthy populations for the presence of antibodies to infections on a national level and with the opportunity for longitudinal sampling of returning donors. Key messages • The relationship between blood establishments and public health should be further explored in the future to support infectious disease surveillance programmes. • Blood donor studies can provide vital baseline data of healthy populations.

Management of Biofilm with Breast Implant Surgery.

After studying this article, the participant should be able to: 1. Understand how bacteria negatively impact aesthetic and reconstructive breast implants. 2. Understand how bacteria infect breast implants. 3. Understand the evidence associated with common implant infection-prevention strategies, and their limitations. 4. Understand why implementation of bacteria-mitigation strategies such as antibiotic administration or "no-touch" techniques may not indefinitely prevent breast implant infection. Bacterial infection of aesthetic and reconstructive breast implants is a common and expensive problem. Subacute infections or chronic capsular contractures leading to device explantation are the most commonly documented sequelae. Although bench and translational research underscores the complexities of implant-associated infection, high-quality studies with adequate power, control groups, and duration of follow-up are lacking. Common strategies to minimize infections use antibiotics-administered systemically, in the breast implant pocket, or by directly bathing the implant before insertion-to limit bacterial contamination. Limiting contact between the implant and skin or breast parenchyma represents an additional common strategy. The clinical prevention of breast implant infection is challenged by the clean-contaminated nature of breast parenchyma, and the variable behavior of not only specific bacterial species but also their strains. These factors impact bacterial virulence and antibiotic resistance.

The role of the plasmid-mediated fluoroquinolone resistance genes as resistance mechanisms in pediatric infections due to Enterobacterales.

Fluoroquinolones (FQs) are not commonly prescribed in children, yet the increasing incidence of multidrug-resistant (MDR) Enterobacterales (Ent) infections in this population often reveals FQ resistance. We sought to define the role of FQ resistance in the epidemiology of MDR Ent in children, with an overall goal to devise treatment and prevention strategies. A case-control study of children (0-18 years) at three Chicago hospitals was performed. Cases had infections by FQ-susceptible, β-lactamase-producing (bla) Ent harboring a non- or low-level expression of PMFQR genes (PMFQS Ent). Controls had FQR infections due to bla Ent with expressed PMFQR genes (PMFQR Ent). We sought bla genes by PCR or DNA (BD Max Check-Points assay®) and PMFQR genes by PCR. We performed rep-PCR, MLST, and E. coli phylogenetic grouping. Whole genome sequencing was additionally performed on PMFQS Ent positive isolates. Demographics, comorbidities, and device, antibiotic, and healthcare exposures were evaluated. Predictors of infection were assessed. Of 170 β-lactamase-producing Ent isolates, 85 (50%) were FQS; 23 (27%) had PMFQR genes (PMFQS cases). Eighty-five (50%) were FQR; 53 (62%) had PMFQR genes (PMFQR controls). The median age for children with PMFQS Ent and PMFQR Ent was 4.3 and 6.2 years, respectively (p = NS). Of 23 PMFQS Ent, 56% were Klebsiella spp., and of 53 PMFQR Ent, 76% were E. coli. The most common bla and PMFQR genes detected in PMFQS Ent were bla SHV ESBL (44%) and oqxAB (57%), and the corresponding genes detected in PMFQR Ent were bla CTX-M-1-group ESBL (79%) and aac(6')-Ib-cr (83%). Whole genome sequencing of PMFQS Ent revealed the additional presence of mcr-9, a transferable polymyxin resistance gene, in 47% of isolates, along with multiple plasmids and mobile genetic elements propagating drug resistance. Multivariable regression analysis showed that children with PMFQS Ent infections were more likely to have hospital onset infection (OR 5.7, 95% CI 1.6-22) and isolates containing multiple bla genes (OR 3.8, 95% CI 1.1-14.5). The presence of invasive devices mediated the effects of healthcare setting in the final model. Differences in demographics, comorbidities, or antibiotic use were not found. Paradoxically, PMFQS Ent infections were often hospital onset and PMFQR Ent infections were community onset. PMFQS Ent commonly co-harbored multiple bla and PMFQR genes, and additional silent, yet transferrable antibiotic resistance genes such as mcr-9, affecting therapeutic options and suggesting the need to address infection prevention strategies to control spread. Control of PMFQS Ent infections will require validating community and healthcare-based sources and risk factors associated with acquisition.

Molecular Characteristics and Prevalence of Rifampin Resistance in Staphylococcus aureus Isolates from Patients with Bacteremia in South Korea.

Rifampin resistance (RIF-R) in Staphylococcus aureus (S. aureus) with rpoB mutations as one of its resistance mechanisms has raised concern about clinical treatment and infection prevention strategies. Data on the prevalence and molecular epidemiology of RIF-R S. aureus blood isolates in South Korea are scarce. We used broth microdilution to investigate RIF-R prevalence and analyzed the rpoB gene mutation in 1615 S. aureus blood isolates (772 methicillin-susceptible and 843 methicillin-resistant S. aureus (MRSA)) from patients with bacteremia, between 2008 and 2017. RIF-R prevalence and antimicrobial susceptibility were determined. Multilocus sequence typing was used to characterize the isolate's molecular epidemiology; Staphylococcus protein A (spa), staphylococcal cassette chromosome mec (SCCmec), and rpoB gene mutations were detected by PCR. Among 52 RIF-R MRSA isolates out of 57 RIF-R S. aureus blood isolates (57/1615, 0.4%; 5 methicillin-susceptible and 52 MRSA), ST5 (44/52, 84.6%), SCCmec IIb (40/52, 76.9%), and spa t2460 (27/52, 51.9%) were predominant. rpoB gene mutations with amino acid substitutions showed that A477D (17/48, 35.4%) frequently conferred high-level RIF resistance (MIC > 128 mg/L), followed by H481Y (4/48, 8.3%). RIF-R S. aureus blood isolates in South Korea have unique molecular characteristics and are closely associated with rpoB gene mutations. RIF-R surveillance through S. aureus-blood isolate epidemiology could enable effective therapeutic management.

Urinary Tract Infections After Urogynecologic Surgery: Risk Factors, Timeline, and Uropathogens

ABSTRACT Postoperative urinary tract infection (PO-UTI) is seen in 6.4%–32% of stress urinary incontinence (SUI) and/or pelvic organ prolapse (POP) surgeries despite perioperative antibiotic prophylaxis. Postoperative complications associated with PO-UTI include increased mortality and longer hospitalization. Increasing prevalence of resistance to antibiotics and antibiotic stewardship principles necessitate both the improvement of infection prevention strategies and judicious antibiotic prescriptions. Four factors are known to increase PO-UTI risk: (1) recurrent UTI (RUTI) history, (2) preoperative UTI, (3) day-of-surgery UTI, and (4) prolonged postoperative catheterization. This study intended to determine (1) risk factors of PO-UTI and PO-RUTI, (2) preoperative and postoperative UTI temporal distribution, and (3) detected uropathogens in a large database. The study used medical record data of all SUI/POP surgical procedures performed in the Kaiser Southern California Hospital system from January 1, 2008 to December 31, 2016 for women 18 years of age or older. Procedures used Current Procedural Terminology codes for identifying and subcategorizing surgical procedures and their route (SUI or POP; abdominal or vaginal, respectively). The study-wide definition of UTI was as follows: (1) positive standard urine culture of greater than 105 CFU/mL of ≤2 uropathogens, or (2) prescription of urinary antibiotics prescribed for the indication of UTI symptoms. The analysis consisted of 21,063 urogynecologic surgical procedures performed on 20,051 women (33,626 POP and/or SUI procedures), with 22,641 UTI events being diagnosed in 10,091 women. Mean age was 56.9 years, and mean BMI was 29.1. The cohort underwent surgery for only SUI (35.4%), only POP (32.7%), or POP/SUI combined (31.9%). In the 13.5 months postoperatively, 11,976 UTIs were diagnosed in 6733 women. The first month experienced a sharp increase compared with the preoperative year, the second month increased further, and the third month showed leveling of PO-UTI incidence. Prescribed antibiotics captured most UTI events (13,337 or 58.3%). Prescribed antibiotics, in order of most-prescribed to least-prescribed, were as follows: ciprofloxacin (33.7%), cephalexin (21.4%), nitrofurantoin (20.4%), and sulfamethoxazole-trimethoprim (17.6%). The study determined that most PO-UTIs occurred within the first 2 months, with many of these being diagnosed within 2 weeks of surgery. For those patients already having a history of RUTI, RUTI significantly increases in postoperative year 1 when compared with the preoperative year. All patients undergoing SUI procedures had increased PO-RUTI risks compared with their POP-only group peers. Escherichia coli was the most common pathogen found. Risk and event timing were affected by surgical indication: although surgery for only SUI had a lower 6-week PO-UTI risk, it was counterintuitively associated with a higher PO-RUTI risk. Multivariate regression revealed predictable risk factors for PO-UTI: OAB, history of diabetes, history of preoperative UTI within 6 weeks of surgery, history of RUTI, stent and catheter placement. A more confusing finding was the association of a vaginal estrogen prescription with increased short-term PO-UTI risk, possibly related to its use in women with a history of RUTI, but more probably related to the postmenopausal status of many of the women in the dataset. The study recommends preoperative assessment with the purpose of identifying and eliminating UTIs within 6 weeks before surgery, as well as development of protocols for enhanced prophylaxis for women at increased risk such as diabetics and women with preoperative RUTI.

Herpes zoster associated with stroke incidence in people living with human immunodeficiency virus: a nested case–control study

BackgroundThe incidence of stroke is increasing among younger people with human immunodeficiency virus (HIV). The burden of stroke has shifted toward the young people living with HIV, particularly in low- and middle-income countries. People infected with herpes zoster (HZ) were more likely to suffer stroke than the general population. However, the association of HZ infection with the incidence of stroke among patients with HIV remains unclear.MethodsA nested case–control study was conducted with patients with HIV registered in the Taiwan National Health Insurance Research Database in 2000–2017. A total of 509 stroke cases were 1:10 matched to 5090 non-stroke controls on age, sex, and date of first stroke diagnosis. Logistic regression models were used to estimate the odds ratio and 95% confidence intervals (CI) of stroke incidence.ResultsThe odds ratio of stroke was significantly higher in the HIV-infected population with HZ (adjusted odds ratio [AOR]: 1.85, 95% CI: 1.42–2.41). A significantly increased AOR of stroke was associated with hypertension (AOR: 3.53, 95% CI: 2.86–4.34), heart disease (AOR: 2.32, 95% CI: 1.54–3.48), chronic kidney disease (AOR: 1.82, 95% CI: 1.16–2.85), hepatitis C virus infection (AOR: 1.49, 95% CI: 1.22–1.83), hyperlipidemia (OR: 1.41, 95% CI: 1.12–1.78), and treatment with protease inhibitors (AOR: 1.33, 95% CI: 1.05–1.69).ConclusionsOur findings suggest that HZ concurrent with HIV may increase the risk of stroke. The incidence rates of stroke were independent of common risk factors, suggesting strategies for early prevention of HZ infection among people living with HIV.

Uptake of hepatitis B vaccination and associated factors among health sciences students, Mogadishu, Somalia.

Hepatitis B is a potentially fatal liver infection caused by the hepatitis B virus (HBV). It is a serious issue for global health. It considerably raises the risk of cirrhosis and liver cancer-related death and can result in chronic infection. The risk of infection is high among health sciences students due to the risk of occupational contact with fluids of infected patients and the risk of needle stick injury. The most effective way of preventing HBV infection is the vaccination of students prior to their posting to healthcare settings. There is no data available about HBV vaccination uptake among Health Sciences students in Somalia. Therefore, this study aimed to determine HBV vaccination uptake and associated factors toward HBV among health science students in Somalia. A cross-sectional study was undertaken among health sciences students from August to October 2022. Data were gathered using Kobo Toolbox using a standardized questionnaire with questions on characteristics, knowledge attitude, and HBV prevention practices. A total of 569 students were involved in the study. Stata version 15 was utilized for the analysis. Bivariate and multivariate logistic regression analysis, as well as descriptive statistics, were performed. In order to assess the existence and significance of the relationship between the outcome and risk factors, an adjusted odds ratio with a 95% confidence interval (CI) was used. Statistical significance was considered as a p-value ≤0.05. Of the 569 study participants, 33.4% (95%CI: 29.6-37.4) received a full dose of the HBV vaccine in this study. Participants had good HBV prevention knowledge, attitudes, and practices at 69.6, 37.96, and 50.6%, respectively. The lack of access and the high cost of the vaccine were the reasons for not taking the vaccine. Second-year [AOR: 0.22 (0.12-0.43)]. Positive attitude [AOR: 0.54 (0.31-0.93)], and good practice [AOR: 6.99 (3.62-13.5)]. The study indicated that 33.4% of health sciences students had received the required HBV vaccination doses, academic year, attitude, and practice were significantly associated with full-dose vaccination status. The unavailability of the vaccine and the high cost of vaccination were the most common reasons for not taking the vaccine. It is recommended that students receive vaccinations before beginning clinical rotations, and give instruction on infection prevention strategies and general precautions, particularly regarding HBV infection.

Seroprevalence, Risk Factors and Maternal-Fetal Outcomes of Toxoplasma gondii in Pregnant Women from WHO Eastern Mediterranean Region: Systematic Review and Meta-Analysis.

The protozoan parasite Toxoplasma gondii may cause serious illness in the immunocompromised. The Toxoplasma gondii seropositive prevalence in pregnant women in WHO Eastern Mediterranean Region countries is inconsistent in the literature and it is associated with outcomes that have not be fully elucidated, hence the need for a better understanding of the pooled seroprevalence and associated maternal and fetal outcomes. The objective was to conduct a systematic literature review and determine the pooled prevalence of WHO Eastern Mediterranean Regional countries' pregnant women's seroprevalence of Toxoplasma gondii and the maternal-fetal outcomes. This quantitative study examined WHO Eastern Mediterranean countries' maternal-fetal outcomes and Toxoplasma gondii prevalence in pregnant women. The targeted population was pregnant women, while the primary outcome was seropositivity of Toxoplasma gondii, while other outcomes such as maternal and fetal associations and risk factors were determined PubMed, SCOPUS, MEDLINE, and Index Medicus for the Eastern Mediterranean Region (IMEMR) databases were searched up until 30 January 2023. The search terms used were "Toxoplasma gondii" OR "Toxoplasma infection" AND "Pregnant woman" or pregnan* OR Antenatal OR Prenatal OR Gravidity OR Parturition OR Maternal AND WHO Eastern Mediterranean Region). OpenMeta-Analyst and Jamovi were used to analyze the generated data. In total, 95 of 2947 articles meeting the inclusion criteria examined Toxoplasma gondii prevalence in pregnant women from WHO Eastern Mediterranean countries. The pooled prevalence of Toxoplasma gondii in pregnant women was 36.5% (95%CI: 32.6-40.4) with a median value of 35.64%, range values of 1.38-75.30%, with 99.61% heterogeneity. The pooled seroprevalence of IgG of Toxoplasma gondii was 33.5% (95%CI: 29.8-37.2) with a median value of 33.51%, and a range values of 1.38-69.92%; the pooled seroprevalence of IgM was 3.6% (95%CI: 3.1-4.1)) with a median value of 3.62 and range values of 0.20-17.47%, while cases of pooled seroprevalence of both IgG and IgM positivity was 3.0% (95%CI: 1.9-4.4) with a median value of 2.05 and a range values of 0.05-16.62%. Of the Toxoplasma gondii seropositive women, 1281/3389 (34.8%) 174/1765 (32.9%), 1311/3101 (43.7%), and 715/1683 (40.8%) of them had contact with cats, drank unprocessed milk, ate raw or undercooked meat and ate unwashed raw vegetables, respectively. The maternal-fetal outcomes associated with Toxoplasma gondii seropositivity were a history of abortions, miscarriage, stillbirth, intrauterine fetal death, and premature birth, which were found in 868/2990 (32.5%), 112/300 (36.1%), 111/375 (25.7%), 3/157 (1.9%) and 96/362 (20.1%) of women who tested positive for Toxoplasma gondii antibodies. The study found a high proportion of Toxoplasma gondii seroprevalence in pregnant women in the WHO Eastern Mediterranean Region, which may be linked to poor outcomes for mothers and their babies. Thus, pregnant women require monitoring and comprehensive prevention strategies for Toxoplasma gondii infection.

Investigating Resistance to Carbapenems in Enterobacterales: A Descriptive Epidemiological Study of 2021 Screening in an Italian Teaching Hospital.

Antimicrobial resistance (AMR) presents a growing threat to global healthcare. This descriptive epidemiological study investigates the prevalence and characteristics of Enterobacterales with AMR factors in a tertiary teaching hospital in Italy over the course of the year 2021. In 2021, the prevalence of colonisation by Enterobacterales with AMR factors in patients was 1.08%. During the observation period, a total of 8834 rectal swabs were performed, with 1453 testing positive. A total of 5639 rectal swabs were performed according to a hospital procedure for the active screening of MDRO colonisation at the time of admission. Of these, 679 were positive for microorganisms under surveillance, and 74 patients were colonised with Enterobacterales, predominantly Klebsiella pneumoniae and Escherichia coli. Antibiotic resistance factors were observed in 61 of these 74 patients (82.43%) of these patients, with NDM and KPC being the most frequent resistance factors. A statistically significant trend in positive swabs was observed across different ward categories (surgery, ICUs, and medical wards). Regarding specific trends, the rate of positive admission screening in medical and surgical wards was higher than in ICU wards. The results highlight the ease with which Enterobacterales develops resistance across different ward categories. The findings underscore the need for adjusted screening protocols and tailored infection prevention strategies in various care settings.
