Proposed Framework for Conducting Clinically Relevant Translational Biomarker Research for the Diagnosis, Prognosis and Management of Sepsis.

Although the diagnosis of sepsis requires the identification of the three components of infection, a systemic inflammation response, and organ dysfunction, there is currently no consensus on gold-standard criteria. There are however suggested tools and tests, which have been proposed in international guidelines, including those produced by the Surviving Sepsis Campaign. Biomarkers play an important role in these tools and tests, and numerous heterogeneous studies have been performed to evaluate their respective clinical utility. Our review of the current practice shows that no biomarkers of infection, systemic inflammation response, organ dysfunction and sepsis are currently specifically recommended, which is probably due to the lack of standardization of studies. We therefore propose to define a framework for conducting clinically relevant translational biomarker research and seek to establish ideal criteria that can be applied to an infection, systemic inflammation response, organ dysfunction and sepsis biomarkers, which can enable early screening of sepsis, diagnosis of sepsis at the time of clinical suspicion and monitoring of sepsis treatment efficacy.

Pancreatic stone protein as a biomarker for the early diagnosis of post-operative peritonitis, intra-abdominal infection and sepsis.

The diagnosis of intra-abdominal infection and post-operative peritonitis based on clinical examination, biomarkers and radiological signs, should be made as early as possible to improve outcomes and decrease mortality through early and optimal source control, adequate surgery and appropriate antibiotic therapy (Montravers et al. Therapeutic management of peritonitis: a comprehensive guide for intensivists. Intensive Care Med 2016;42:1234-47). However, the indication and the timing of the surgery is often not an easy decision. This case presents the use of a novel early biomarker of infection and sepsis, pancreatic stone protein (Fidalgo et al. Pancreatic stone protein: review of a new biomarker in sepsis. J Clin Med 2022;11:1085), as a tool to aid in the diagnosis of intra-abdominal infection and post-operative peritonitis and to help guide the decision for adequate surgeries in a patient with intra-abdominal infection and post radical prostatectomy peritonitis.

Preparedness and Reorganization of Care for Coronavirus Disease 2019 Patients in a Swiss ICU: Characteristics and Outcomes of 129 Patients.

OBJECTIVES: In many countries, large numbers of critically ill patients with coronavirus disease 2019 are admitted to the ICUs within a short period of time, overwhelming usual care capacities. Preparedness and reorganization ahead of the wave to increase ICU surge capacity may be associated with favorable outcome. The purpose of this study was to report our experience in terms of ICU organization and anticipation, as well as reporting patient characteristics, treatment, and outcomes. DESIGN: A prospective observational study. SETTING: The division of intensive care at the Geneva University Hospitals (Geneva, Switzerland). PATIENTS: All consecutive adult patients with acute respiratory failure due to coronavirus disease 2019 admitted in the ICU between March 9, 2020, and May 19, 2020, were enrolled. Patients' demographic data, comorbidities, laboratory values, treatments, and clinical outcomes were collected. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The ICU was reorganized into cells of six to eight patients under the care of three physicians and five nurses. Its capacity increased from 30 to 110 beds, fully equipped and staffed, transforming the surgical intermediate care unit, the postoperative care facility, and operating theaters into ICUs. Surge capacity has always exceeded the number of patients hospitalized. Among 129 critically ill patients with severe acute hypoxemic respiratory failure, 96% required invasive mechanical ventilation. A total of 105 patients (81%) were discharged alive and 24 died, corresponding to a mortality of 19%. Patients who died were significantly older, with higher severity scores at admission, had higher levels of d-dimers, plasma creatinine, high-sensitive troponin T, C-reactive protein, and procalcitonin, and required more frequent prone sessions. CONCLUSIONS: A rapid increase in ICU bed capacity, including adequate equipment and staffing, allowed for a large number of critically ill coronavirus disease 2019 patients to be taken care of within a short period of time. Anticipation and preparedness ahead of the wave may account for the low mortality observed in our center. These results highlight the importance of resources management strategy in the context of the ongoing coronavirus disease 2019 pandemic.

Use of the Airtraq as the primary technique to manage anticipated difficult airway: a report of three cases.

The Airtraq laryngoscope (Prodol Meditec S.A., Vizcaya, Spain) is a new disposable optical laryngoscope designed to facilitate intubation in an uncomplicated or difficult airway. Its distinctive shape and its optical system can provide a full view of the glottis without the need to align the oropharyngeal axis. The use of this device as the primary technique to manage the airway of three patients with a previous history of difficult intubation related to difficult laryngoscopy is presented.
