Background: Guidelines recommend 5-7 days of antibiotic treatment in patients with surgical infection and adequate source control. This nationwide stewardship intervention aimed to reduce the duration of treatments in surgical patients to <7 days.

Methods: Prospective cohort study evaluating surgical patients receiving antibiotics ≥7 days in 32 hospitals.

Surgical Infection Reduction Program of the Observatory of Surgical Infection (PRIQ-O): Delphi prioritization and consensus document on recommendations for the prevention of surgical site infection.

Surgical site infection is the most frequent and avoidable complication of surgery, but clinical guidelines for its prevention are insufficiently followed. We present the results of a Delphi consensus carried out by a panel of experts from 17 Scientific Societies with a critical review of the scientific evidence and international guidelines, to select the measures with the highest degree of evidence and facilitate their implementation. Forty measures were reviewed and 53 recommendations were issued.

Scientific evidence of the duration of antibiotic treatment in intra-abdominal infections with surgical focus control.

A non-systematic review of the published scientific evidence has been carried out on the duration of empirical antibiotic treatment in surgical intra-abdominal infections (IIA) with effective focus control. Given the progressive increase in antibiotic resistance, it is urgent to have strategies to reduce the pressure on the microbiota. The American guidelines made by Mazuski et al.

An interventional nationwide surveillance program lowers postoperative infection rates in elective colorectal surgery. A cohort study (2008-2019).

Background: Colorectal surgery is associated with the highest rate of surgical site infection (SSI). This study analyses the effectiveness of an interventional surveillance program on SSI rates after elective colorectal surgery.

Material And Methods: Cohort study showing temporal trends of SSI rates and Standardized Infection Ratio (SIR) in elective colorectal surgery over a 12-year period.

A Modular and Expandable Ecosystem for Metabolomics Data Annotation in R.

Liquid chromatography-mass spectrometry (LC-MS)-based untargeted metabolomics experiments have become increasingly popular because of the wide range of metabolites that can be analyzed and the possibility to measure novel compounds. LC-MS instrumentation and analysis conditions can differ substantially among laboratories and experiments, thus resulting in non-standardized datasets demanding customized annotation workflows. We present an ecosystem of R packages, centered around the , and packages that together provide a modular infrastructure for the annotation of untargeted metabolomics data.

Oral Antibiotic Prophylaxis Lowers Surgical Site Infection in Elective Colorectal Surgery: Results of a Pragmatic Cohort Study in Catalonia.

Background: The role of oral antibiotic prophylaxis (OAP) and mechanical bowel preparation (MBP) in the prevention of surgical site infection (SSI) after colorectal surgery is still controversial. The aim of this study was to analyze the effect of a bundle including both measures in a National Infection Surveillance Network in Catalonia.

Methods: Pragmatic cohort study to assess the effect of OAP and MBP in reducing SSI rate in 65 hospitals, comparing baseline phase (BP: 2007-2015) with implementation phase (IP: 2016-2019).

HERMES: a molecular-formula-oriented method to target the metabolome.

Comprehensive metabolome analyses are essential for biomedical, environmental, and biotechnological research. However, current MS1- and MS2-based acquisition and data analysis strategies in untargeted metabolomics result in low identification rates of metabolites. Here we present HERMES, a molecular-formula-oriented and peak-detection-free method that uses raw LC/MS1 information to optimize MS2 acquisition.
