Objective: To describe the capacity of a broad spectrum of cytokines and growth factors to predict ICU admission and/or death in patients with severe COVID-19.
Design: An observational, analytical, retrospective cohort study with longitudinal follow-up.
Setting: Hospital Universitario Príncipe de Asturias (HUPA).
Participants: 287 patients diagnosed with COVID-19 admitted to our hospital from 24 March to 8 May 2020, followed until 31 August 2020.
Main Outcome Measures: Profiles of immune response (IR) mediators were determined using the Luminex Multiplex technique in hospitalized patients within six days of admission by examining serum levels of 62 soluble molecules classified into the three groups: adaptive IR-related cytokines ( = 19), innate inflammatory IR-related cytokines ( = 27), and growth factors ( = 16).
Results: A statistically robust link with ICU admission and/or death was detected for increased serum levels of interleukin (IL)-6, IL-15, soluble (s) RAGE, IP10, MCP3, sIL1RII, IL-8, GCSF and MCSF and IL-10. The greatest prognostic value was observed for the marker combination IL-10, IL-6 and GCSF.
Conclusions: When severe COVID-19 progresses to ICU admission and/or death there is a marked increase in serum levels of several cytokines and chemokines, mainly related to the patient's inflammatory IR. Serum levels of IL-10, IL-6 and GCSF were most prognostic of the outcome measure.

Introduction: The burden of severe asthma on patients, especially on those with concomitant chronic rhinosinusitis with nasal polyps (CRSwNP), is substantial. Treatment intensification with oral corticosteroids is a common strategy for managing severe asthma exacerbations; however, prolonged exposure to systemic corticosteroids is associated with multisystem toxicity. This study aimed to quantify the association between oral corticosteroid use and annual asthma-related costs in patients with severe asthma with or without CRSwNP.

This study explores the association between serum chloride concentrations and all-cause mortality among patients in the Surgical Intensive Care Unit (SICU). Employing a retrospective cohort design, the study utilized data extracted from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database, specifically focusing on individuals admitted to the surgical/trauma ICUs. This dataset encompassed demographic profiles, laboratory findings, historical medical data, vital statistics, and variables pertinent to prognosis.

Objective: Traumatic hemorrhagic cerebral contusions are a well-established cause of morbidity and mortality in neurosurgery. This study aimed to determine prognostic factors for long-term functional outcomes and longitudinal contusion volume changes in traumatic brain injury (TBI) patients.
Methods: Data from 285 patients with traumatic cerebral contusions were retrospectively reviewed to identify variables predictive of initial contusion volume, contusion expansion on short-term follow-up imaging, and functional outcomes according to the modified Rankin Scale (mRS).
