Background
Bacteremia is a leading cause of morbidity and mortality worldwide. Rising prevalence and antimicrobial resistance (AMR) are critical public health issues. This study aims to determine the prevalence of bacteremia and the AMR pattern among patients in South Lebanon.
Methods
A cross-sectional study analyzed 76 positive blood cultures from Hammoud and Labib Hospitals in South Lebanon between September 2023 and March 2024. The phenotype and antimicrobial susceptibility of gram-positive and gram-negative were determined by using disk diffusion. Genotypically, polymerase chain reaction was used to detect the carbapenemase-resistant Enterobacterales (CRE), extended-spectrum β-lactamases (ESBL), and methicillin-resistant Staphylococcus aureus genes.
Results
Out of 76 isolates, 38 (50%) were gram-positive and 38 (50%) were gram-negative. Escherichia coli was the most common among gram-negative (18. 42%), with 10.52% ESBL and 3.94% CRE. Staphylococcus coagulase negative was the most common among gram-positive (40.78%), followed by Staphylococcus aureus (6.57%), with 3.94% methicillin-resistant S. aureus. The prevalent ESBL gene was CTX-M (100%), and for the CRE, NDM (66.66%) was the most common gene. Regarding S. aureus, 66.66% were mecA.
Discussion
The diverse bacteremia isolates and resistance genes in South Lebanon reflect global variability in incidence and resistance profiles.
Conclusions
High rates of bacteremia and AMR in South Lebanon underscore the need for effective antibiotic stewardship programs.

Background
To pursue an irreducible minimum overall surgical site infection (SSI) rate, a 32-bed surgical hospital employed an outside consultant and performed sterile processing and surgery internal audits: No obvious improvements were identified. A 10-year review determined that 70% of SSI’s were spine procedure patients. After a nasal decolonization product literature review, an intervention was implemented. The purpose of this study was to assess if the intervention impacted spine SSI rates.
Methods
A 36-month implementation science study was conducted. The 18-month intervention was the immediate preoperative application of a manufactured presaturated 10% povidone-iodine nasal decolonization product in spine surgery patients, with monthly product application documentation surveillance feedback to the preoperative staff. Chi-square test was used to determine the difference in types of spine SSI surgery rates pre and post intervention.
Results
Overall spine SSI decreased 35.7% (P = .04) with a 58.7% reduction in superficial incisional SSI (P = .02). The 16.1% decline in deep incisional SSI was not significant (P = .29).
Conclusions
Within this hospital, conducting 7,576 surgical spine procedures over 36 months, with the immediate preoperative application of a presaturated 10% povidone-iodine nasal decolonization product, the only intervention in SSI prevention protocol, produced a statistically significant decrease in spine patient SSI rate percent.

Chronic obstructive pulmonary disease (COPD) is a risk factor for herpes zoster. Vaccination can prevent or attenuate herpes zoster and its related complications. However, evidence regarding vaccine uptake among patients with COPD is limited. Therefore, this study aimed to evaluate trends in herpes zoster vaccination and characteristics associated with vaccination among US older adults with COPD.
Methods
Data from the 2008 to 2022 National Health Interview Survey were used. Participants aged ≥50 years were included. Joinpoint regression analysis was performed to analyze trends in herpes zoster vaccination. A multivariable logistic regression model was used to identify factors associated with vaccination.
Results
From 2008 to 2022, an increasing trend in herpes zoster vaccination was observed (average annual percent change = 15.10, P < .01). This increasing trend was also observed when stratified by age groups. Disparities in vaccination were found across several factors, including age, sex, race or ethnicity, region, educational level, health insurance, income, smoking status, perceived health status, and flu and pneumococcal vaccination.
Conclusions
There has been an upward trend in herpes zoster vaccination over the past 15 years among older adults with COPD. Disparities across several characteristics existed, underscoring the necessity for targeted policies and interventions to promote equity in vaccination.

Background
New elastomeric half-mask respirator (EHMR) models without exhalation valves (EVs) or with exhalation valve filters (EVFs) are facilitating expanded use in health settings to reduce workers’ exposure to airborne hazards while acting as source control to prevent pathogen spread. The physical comfort of new models has not been assessed in comparison to previously used EHMRs with EVs.
Methods
Researchers assessed 1,962 health care and emergency medical service personnels’ self-reported adverse experiences from 2 cohorts while wearing EHMR models with EVs (cohort 1, n = 1,080) and without EVs or with EVFs (cohort 2, n = 882). Fisher exact test identified differences between the cohorts accounting for organizational factors when possible.
Results
Cohort 1 respondents experienced communication challenges and discomfort when wearing the EHMR > 1 hour statistically significantly more often than cohort 2. Cohort 2 respondents reported statistically significantly more instances of difficulty breathing, moisture buildup, being uncomfortable to wear < 1 hour, and being uncomfortably warm.
Conclusions
Discomfort is prevalent among end users and more often among those wearing EHMRs without an EV/with an EVF. As EHMR research and development advances, prevalence in use may increase for emergency and routine situations. Organizations may not only need guidance about respirator selection but also model-specific selection.

Background
We aimed to determine the prevalence of genes associated with high-level mupirocin and biocide resistance in methicillin-resistant Staphylococcus aureus (MRSA) isolates among hospitalized patients and to characterize their genomic and epidemiologic features.
Methods
Study conducted on an integrated health system. Clinical cultures with MRSA from hospitalized patients collected between March 1, 2023, and January 20, 2024 underwent prospective whole-genome sequencing, including assessment for the presence of markers of resistance against mupirocin (mupA) and biocides (qac). Demographic and clinical characteristics were reviewed.
Results
We analyzed 463 MRSA isolates. The overall prevalence of mupA(+), qacA(+), and qacC(+) genes was 22.0%, 2.4%, and 19.0%, respectively. Most mupA(+) isolates belonged to ST8, but ST8732 (a novel variant of ST8) had the highest prevalence of mupA(+) isolates at 95%. Patients mupA(+) were older, and none of the isolates from pediatric patients harbored this gene.
Discussion
Through prospective whole-genome sequencing of MRSA isolates, we detected a prevalence of genes conferring mupirocin resistance considerably higher than previously reported, particularly among MRSA ST8 variants.
Conclusions
Our findings highlight the need for monitoring resistance to agents used for the prevention of S aureus infections, as these trends have implications for infection prevention programs and public health at large.

Background
Hospital-acquired infections (HAIs) increase morbidity, mortality, and health care costs. Effective hand hygiene (HH) is crucial for prevention, but achieving high compliance remains challenge. This study explores using machine learning to integrate an electronic HH auditing system with electronic health records to predict HAIs.
Methods
A retrospective cohort study was conducted at a Brazilian hospital during 2017-2020. HH compliance was recorded electronically, and patient data were collected from electronic health records. The primary outcomes were HAIs per CDC/National Healthcare Safety Network surveillance definitions. Machine learning algorithms, balanced with Random Over Sampling Examples (ROSE), were utilized for predictive modeling, including generalized linear models (GLM); generalized additive models for location, scale, and shape (GAMLSS); random forest; support vector machine; and extreme gradient boosting (XGboost).
Results
125 of 6,253 patients (2%) developed HAIs and 920,489 HH opportunities (49.3% compliance) were analyzed. A direct correlation between HH compliance and HAIs was observed. The GLM algorithm with ROSE demonstrated superior performance, with 84.2% sensitivity, 82.9% specificity, and a 93% AUC.
Conclusions
Integrating electronic HH auditing systems with electronic health records and using machine learning models can enhance infection control surveillance and predict patient outcomes. Further research is needed to validate these findings and integrate them into clinical practice.

Background
This study explores the infrastructural and organizational risk factors for health care–associated (HCA) Clostridioides difficile infections (CDIs) and methicillin-resistant Staphylococcus aureus (MRSA) in hospitals.
Methods
This is a retrospective observational study involving all eligible inpatient units from 12 hospitals in British Columbia, Canada, from April 1, 2020 to September 16, 2021. The outcomes were the average HCA CDI or MRSA rates. Covariates included, but were not limited to, infection control factors (eg, hand hygiene rate), infrastructural factors (eg, unit age), and organizational factors (eg, hallway bed utilization). Multivariable regression was performed to identify statistically significant risk factors.
Results
Older units were associated with higher HCA CDI rates (adjusted relative risk [aRR]: 0.012; 95% confidence interval (CI) [0.004, 0.020]). Higher HCA MRSA rates were associated with decreased hand hygiene rate (aRR: −0.035; 95% CI [−0.063, −0.008]), higher MRSA bioburden (aRR: 9.008; 95% CI [5.586, 12.429]), increased utilization of hallway beds (aRR: 0.680; 95% CI [0.094, 1.267]), increased nursing overtime rate (aRR: 5.018; 95% CI [1.210, 8.826]), and not keeping the clean supply room door closed (aRR: −0.283; 95% CI [−0.536, −0.03]).
Conclusions
The study confirmed the multifaceted nature of infection prevention and emphasized the importance of interdepartmental collaboration to improve patient safety.

Multivariable regression was performed to identify statistically significant risk factors.</div></div><div><h3>Results</h3><div>Older units were associated with higher HCA CDI rates (adjusted relative risk [aRR]: 0.012; 95% confidence interval (CI) [0.004, 0.020]). Higher HCA MRSA rates were associated with decreased hand hygiene rate (aRR: −0.035; 95% CI [−0.063, −0.008]), higher MRSA bioburden (aRR: 9.008; 95% CI [5.586, 12.429]), increased utilization of hallway beds (aRR: 0.680; 95% CI [0.094, 1.267]), increased nursing overtime rate (aRR: 5.018; 95% CI [1.210, 8.826]), and not keeping the clean supply room door closed (aRR: −0.283; 95% CI [−0.536, −0.03]).</div></div><div><h3>Conclusions</h3><div>The study confirmed the multifaceted nature of infection prevention and emphasized the importance of interdepartmental collaboration to improve patient safety.</div></div>","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":"53 1","pages":"Pages 93-97"},"PeriodicalIF":3.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141995111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
