Biomarkers in Hepatic Disease: A Review Focused on Critically Ill Patients.

The ability to make a diagnosis early and appropriately is paramount for the survival of the critically ill ICU patient. Along with the myriad physical examination and imaging modalities available, biomarkers provide a window on the disease process. Herein we review hepatic biomarkers in the context of the critical care patient.

Association between age of respiratory syncytial virus infection hospitalization and childhood asthma: A systematic review.

Identifying child age of RSV infection associated with increased risk of asthma is important for developing asthma prevention strategies. Our systematic review aimed to comprehensively summarize studies of the association between age of RSV infection and childhood asthma risk. The study protocol was pre-registered, and our study report adhered to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Inclusion criteria were prospective and retrospective cohort studies and case-control studies which assessed the association of age of RSV infection before age 2 years and risk of childhood asthma after age two years. Relevant studies were identified through MEDLINE, Embase, Cochrane and International Clinical Trials Registry Platform (ICTRP) from study inception through May 5, 2023. Studies were evaluated with the Quality In Prognosis Studies (QUIPS) tool. From 149 studies screened, five studies (two prospective cohort studies and three retrospective cohort studies) were included in our systematic review, including 47,603 participants. Available studies only assessed age of severe RSV infection and asthma risk. The included studies used different age categories and outcome definitions, and were rated as having high risk of bias. Two studies had sample sizes of less than 300 and did not provide conclusive results related to age of RSV hospitalization and asthma risk. The other three studies reported RSV hospitalization between age 6 months and 23 months compared with age 0-6 months being associated with a higher odds ratio, hazard ratio, or incidence rate ratio of asthma diagnosis/hospitalization. Due to the heterogeneous epidemiological designs, including exposures and outcome ascertainments of the included studies, we could not perform a meta-analysis, or calculate weighted averages of the effect estimates. Our systematic review highlights a major gap in our knowledge about the relationship between age of RSV infection and asthma risk.

Antimicrobial Stewardship Optimization in the Emergency Department: The Effect of Multiplex Respiratory Pathogen Testing and Targeted Educational Intervention.

BACKGROUND: Antibacterial agents are often prescribed for patients with suspected respiratory tract infections even though these are most often caused by viruses. In this study, we sought to evaluate the effect of Respiratory Pathogen Panel (RPP) PCR result availability and antimicrobial stewardship education on antibiotic prescription rates in the adult emergency department (ED). METHODS: We compared rates of antibacterial and oseltamivir prescriptions between 2 nonconsecutive influenza seasons among ED visits, wherein the latter season followed the implementation of a comprehensive educational stewardship campaign. In addition, we sought to elucidate the effect of RPP-PCR on antibiotic prescriptions, with focus on result availability prior to the conclusion of emergency department encounters. RESULTS: Antibiotic prescription rates globally decreased by 17.9% in the FS-17/18 cohort compared to FS-14/15 (P < 0.001), while oseltamivir prescription rates stayed the same overall (P = 0.42). Multivariate regression across both cohorts revealed that patients were less likely to receive antibiotics if RPP-PCR results were available before the end of the ED visit or if the RPP-PCR result was positive for influenza. Patients in the educational intervention cohort were also less likely to receive an antibiotic prescription. CONCLUSION: This study provides evidence that RPP-PCR results are most helpful if available prior to the end of the provider-patient interaction. Further, these data suggest that detection of influenza remains an influential result in the context of antimicrobial treatment decision making. In addition, these data contribute to the body of literature which supports comprehensive ASP interventions including leadership and patient engagement.

Is It Necessary To Place Prophylactically an Abdominal Drain To Prevent Surgical Site Infection in Abdominal Operations? A Systematic Meta-Review.

BACKGROUND: There is still uncertainty regarding the use of prophylactic drainage in abdominal surgical procedures. This meta-review aimed to summarize systematic reviews and meta-analyses evaluating abdominal drain placement in patients undergoing abdominal procedures, with a focus on surgical site infection and death from infections. METHODS: Systematic reviews and meta-analyses identified in MEDLINE, EMBASE, CINHAL, Cochrane Central Register of Controlled Trials, World Health Organization Regional Medical Databases, and African Index Medicus were reviewed. RESULTS: Fifteen systematic reviews and meta-analyses concerning prophylactic abdominal drainage in abdominal operations were included in this analysis. The median score of methodologic quality was eight (6-10). The majority of meta-analyses found no benefits of prophylactic drainage in reducing surgical site infection, but no significant differences were identified. Three studies demonstrated a significant difference in favor of no drainage, with two regarding cholecystectomy and one on appendectomy (p < 0.05). The quality of evidence provided by each review was mainly low and very low. CONCLUSIONS: Most reviews fail to detect an increased incidence of surgical site infection in the setting of drainage placement but also fail to attribute any specific benefits to the presence of a drain in abdominal procedures.
