Design of a panel of indicators for antibiotic stewardship programs in the Emergency Department. / Diseño de un panel de indicadores para programas de optimización del uso de antimicrobianos en los Servicios de Urgencias.

OBJECTIVE: To develop a panel of indicators to monitor antimicrobial stewardship programs activity in the emergency department. METHODS: A multidisciplinary group consisting of experts in the management of infection in emergency departments and the implementation of antimicrobial stewardship programs (ASP) evaluated a proposal of indicators using a modified Delphi methodology. In the first round, each expert classified the relevance of each proposed indicators in two dimensions (healthcare impact and ease of implementation) and two attributes (prioritization level and frequency). The second round was conducted based on the modified questionnaire according to the suggestions raised and new indicators suggested. Experts modified the prioritization order and rated the new indicators in the same manner as in the first round. RESULTS: 61 potential indicators divided into four groups were proposed: consumption indicators, microbiological indicators, process indicators, and outcome indicators. After analyzing the scores and comments from the first round, 31 indicators were classified as high priority, 25 as intermediate priority, and 5 as low priority. Moreover, 18 new indicators were generated. Following the second round, all 61 initially proposed indicators were retained, and 18 new indicators were incorporated: 11 classified as high priority, 3 as intermediate priority, and 4 as low priority. CONCLUSIONS: The experts agreed on a panel of ASP indicators adapted to the emergency services prioritized by level of relevance. This is as a helpful tool for the development of these programs and will contribute to monitoring the appropriateness of the use of antimicrobials in these units.

Inflammatory processes involved in the alteration of liver function biomarkers in adult hospitalized patients treated with parenteral nutrition.

Introduction: Liver damage has been associated with the accumulation of phytosterols (PS) in patients treated with parenteral nutrition (PN). We aimed to study the association of inflammatory markers with liver function biomarker (LFB) alterations in patients treated with PN containing PS. Materials and methods: Prospective observational study. Simple linear and stepwise multiple linear regression tests and interactions were performed. Results: Nineteen patients were included. In the multivariable model, determinations based on LFBs as dependent and phytosterols (and their fractions) as independent variables showed an association between increases in gamma-glutamyltransferase (GGT) and lanosterol (p < 0.001), stigmasterol (p < 0.001), interleukin-10 (IL-10) × total phytosterols (Phyt) (p < 0.009), tumor necrosis factor-α (TNF-α) × Phyt (p < 0.002), IL-10 × sitosterol (p < 0.002), TNF-α × sitosterol (p < 0.001), IL-10 × campesterol (p < 0.033), IL-10 (p < 0.006 and p < 0.015), TNF-α (p < 0.048 and p < 0.027). Increases in alanine aminotransferase (ALT) were associated with Phyt (p < 0.006), lanosterol (p < 0.016), C-reactive protein (CRP) × campesterol (p < 0.001), interleukin-6 (IL-6) × stigmasterol (p < 0.030), CRP (p < 0.08), and IL-6 (p < 0.042). Alkaline phosphatase (AP) increases were associated with CRP (p < 0.002). Discussion: Inflammation in the presence of plasmatic PS seems to have a synergistic effect in impairing liver function, mainly altering GGT but also ALT.

Effect of Fish Oil Parenteral Emulsion Supplementation on Inflammatory Parameters after Esophagectomy.

(Background) Esophagectomy (EPG) presents high morbidity and mortality. Omega-3 fatty acids (ω-3FA) are a pharmaconutrient with benefits for postoperative morbidity. Studies of ω-3FA administered parenterally after esophagectomy are scarce. This study proposes to investigate the effect of combining fish oil lipid emulsions (LE) administered parenterally with enteral nutrition support. (Methods) Randomization was 1:1:1 in three groups: Group A received a LE mixture of 0.4 g/kg/day of fish oil and 0.4 g/kg/day of LCT/MCT 50:50, Group B received 0.8 g/kg/day of fish oil LE, and Group C received 0.8 g/kg/day of LCT/MCT 50:50. Variables were measured at recruitment time and day +1, +3, and +5. Inflammatory variables studied were Interlukin-6, C-reactive protein (CRP), tumoral necrosis factor-α (TNF-α), IL-10, IL-8 and CD25s. Safety, nutritional parameters and complications were analyzed. (Results) Administration of ω-3LE in the immediate postoperative period did not modulate the earlier inflammatory response. Statistically significant differences were found in IL-6 and CRP overall temporal evolution but were not found when studying the type of LE administered or in patients needing critical care. Administration of ω-3 resulted in safe and improved hypertriglyceridemia, depending on the dose. (Conclusions) ω-3FA has no impact on the early inflammatory postoperative response assessed for a short period but was safe. More studies for longer periods are needed.
