Nasopharyngeal Methicillin-Resistant <italic>Staphylococcus aureus</italic> Carriage and Risk of Percutaneous Endoscopic Gastrostomy-Related Infection: A Systematic Review and Meta-Analysis.
Digestive diseases (Basel, Switzerland)
2026: 1-10
Abstract
Enteral feeding via percutaneous endoscopic gastrostomy (PEG) is commonly used for patients requiring long-term nutritional support. However, PEG insertion carries a risk of infection, including methicillin-resistant Staphylococcus aureus (MRSA) peristomal infections. This systematic review and meta-analysis aimed to evaluate the association between MRSA colonization and the risk of PEG-related infections.A systematic search was conducted in four major databases - Embase, MEDLINE, Cochrane, and Scopus - focusing on studies reporting MRSA colonization and PEG-related infections. Data were analyzed using RevMan v5.3. Odds ratios (OR) were calculated for dichotomous outcomes using a random-effects model. Statistical significance was defined as p < 0.05. Heterogeneity was assessed using the I2 statistic.Five studies encompassing 286 patients were included in the meta-analysis. Among them, 77 patients were nasopharyngeal MRSA-positive, and 209 were MRSA-negative. MRSA colonization was significantly associated with an increased risk of PEG-related peristomal infection (OR: 24.31; 95% CI: 5.20-113.65; p < 0.0001). Moderate heterogeneity was observed among studies (I2 = 69%, p = 0.01), likely reflecting differences in study design and infection definition; however, the overall association remained statistically significant.Nasopharyngeal MRSA colonization is strongly associated with a higher risk of PEG-site infection. These findings highlight the importance of MRSA screening and consideration of colonization status prior to PEG tube insertion. Enhanced infection control strategies should be implemented in MRSA-positive patients to reduce the risk of complications. However, given the limited number of included studies (n = 5; 286 patients), these conclusions should be interpreted with caution. Larger, well-designed studies are needed to validate these associations and identify the most effective preventive measures for MRSA-colonized individuals undergoing PEG placement.

PRO-READ IR:Enhanced PROcedural Information READability for Patient-Centered Care in Interventional Radiology with Large Language Models.
Journal of the American College of Radiology : JACR
2024
Abstract
To evaluate the extent to which GPT-4 can educate patients by generating easily understandable information about the most common Interventional Radiology(IR) procedures.We reviewed 10 IR procedures and prepared prompts for GPT-4 to provide patient educational instructions about each procedure in layman's terms. The instructions were then evaluated by 4-clinical physicians and 9-nonclinical assessors to determine their clinical appropriateness, understandability and clarity utilizing a survey. A grade-level readability assessment was performed using validated metrics to evaluate accessibility to a wide patient population. The same procedures were also evaluated from the patient instructions available at radiologyinfo.org and compared to GPT-generated instructions utilizing a paired t-test.Evaluation by 4-clinical physicians shows that 9 GPT-generated instructions were fully appropriate, whereas arterial embolization instructions was somewhat appropriate. Evaluation by 9-nonclinical assessors shows that paracentesis, dialysis-catheter-placement, thrombectomy, ultrasound-guided-biopsy, and nephrostomy-tube instructions, were rated excellent by 57%, and good by 43%. The arterial-embolization and biliary-drain instructions were rated excellent by 28.6% and good by 71.4%. In contrast, thoracentesis, port-placement, and CT-guided-biopsy instructions received 43% excellent, 43% good, and 14% fair. The readability assessment across all procedural instructions showed a better Flesch-Kincaid mean grade of GPT-4 instructions compared to radiologyinfo.org(7.8±0.87 vs 9.6±0.83,p=0.007) indicating excellent readability at 7-8th grade level compared to 9-10th grade. Additionally there was a lower Gunning-Fog mean Index(10.4±1.2 vs. 12.7±0.93,p=0.006), and higher Flesch Reading Ease mean score (69.4±4.8 vs 51.3±3.9,p=0.0001) indicating better readability.IR procedural instructions generated by GPT-4 can aid in improving health literacy and patient-centered care in IR by generating easily understandable explanations.
