BACKGROUND: Trauma is the leading cause of death and disability for individuals under age 55. Many severely injured trauma patients experience complicated clinical courses despite appropriate initial therapy. We sought to identify novel circulating metabolomic signatures associated with clinical outcomes following trauma. STUDY DESIGN: Untargeted metabolomics and circulating plasma immune mediator analysis was performed on plasma collected during three post-injury time periods (<6h, 6h-24h, D2-D5) in critically ill trauma patients enrolled between April 2004 and May 2013 at UPMC Presbyterian Hospital in Pittsburgh, PA...

The Covid-19 pandemic has caused untold disruption and enhanced mortality rates around the world. Understanding the mechanisms for transmission of SARS-CoV-2 is key to preventing further spread but there is confusion over the meaning of "airborne" whenever transmission is discussed. Scientific ambivalence originates from evidence published many years ago, which has generated mythological beliefs that obscure current thinking. This article gathers together and explores some of the most commonly held dogmas on airborne transmission in order to stimulate revision of the science in the light of current evidence...

BACKGROUND: Metabolic Syndrome (MetS) is highly prevalent worldwide and its individual components obesity, diabetes and hypertension have been identified as risk factors to develop severe COVID-19 illness, however data on MetS and clinical outcomes in COVID-19 is scarce. This study aims to determine association between MetS and severe disease outcomes, i.e. mortality, need for mechanical ventilation and ICU requirement among COVID-19 patients. METHODS: A retrospective multi-hospital cohort study on 1871 patients with confirmed COVID-19 diagnosis...

SARS-CoV2-induced direct cytopathic effects against type II pneumocytes are suspected to play a role in mediating and perpetuating lung damage. The aim of this study was to evaluate serum KL-6 behavior in COVID-19 patients to investigate its potential role in predicting clinical course. Sixty patients (median age IQR, 65 (52-69), 43 males), hospitalized for COVID-19 at Siena COVID Unit University Hospital, were prospectively enrolled. Twenty-six patients were selected (median age IQR, 63 (55-71), 16 males); all of them underwent follow-up evaluations, including clinical, radiological, functional, and serum KL-6 assessments, after 6 (t1) and 9 (t2) months from hospital discharge...

BACKGROUND: In preterm infants, InSurE (Intubation-Surfactant-Extubation) and LISA (less invasive surfactant administration) techniques allow for exogenous surfactant administration while reducing lung injury associated with mechanical ventilation. We compared the acute pulmonary response and lung deposition of surfactant by LISA and InSurE in surfactant-depleted adult rabbits. METHODS: Twenty-six spontaneously breathing surfactant-depleted adult rabbits (6-7 weeks old) with moderate RDS and managed with nasal continuous positive airway pressure were randomized to 3 groups: (1) 200 mg/kg of surfactant by InSurE; (2) 200 mg/kg of surfactant by LISA; (3) no surfactant treatment (Control)...

BACKGROUND: Hypertensive disorders of pregnancy are widespread and have long-standing implications for women's health. Historically, the management of "severe gestational hypertension," or the presence of severely elevated blood pressures without any other signs or symptoms of end-organ damage meeting the criteria for preeclampsia, has been unclear. The new American College of Obstetricians and Gynecologists guidelines based on expert opinion recommend that severe gestational hypertension be treated similarly to preeclampsia with severe features, but data regarding outcomes for women with this diagnosis have been limited...

Ventilator-associated pneumonia (VAP) is a common hospital-acquired infection, leading to high morbidity and mortality. Currently, bronchoalveolar lavage (BAL) is used in hospitals for VAP diagnosis and guiding treatment options. Although BAL collection procedures are invasive, alternatives such as endotracheal aspirates (ETA) may be of diagnostic value, however, their use has not been thoroughly explored. Longitudinal ETA and BAL were collected from 16 intubated patients up to 15 days, of which 11 developed VAP...

The Coronavirus disease 2019 (COVID-19), caused by the novel coronavirus SARS-CoV-2, was first reported in December 2019 in Wuhan, Hubei province, China. This virus has led to 61.8 million cases worldwide being reported as of December 1st, 2020. Currently, there are no definite approved therapies endorsed by the World Health Organization for COVID-19, focusing only on supportive care. Treatment centers around symptom management, including oxygen therapy or invasive mechanical ventilation. Immunotherapy has the potential to play a role in the treatment of SARS-CoV-2...

The homeostatic oxygen sensing system (HOSS) optimizes systemic oxygen delivery. Specialized tissues utilize a conserved mitochondrial sensor, often involving NDUFS2 in complex I of the mitochondrial electron transport chain, as a site of pO2 -responsive production of reactive oxygen species (ROS). These ROS are converted to a diffusible signaling molecule, hydrogen peroxide (H2 O2 ), by superoxide dismutase (SOD2). H2 O2 exits the mitochondria and regulates ion channels and enzymes, altering plasma membrane potential, intracellular Ca2+ and Ca2+ -sensitization and controlling acute, adaptive, responses to hypoxia that involve changes in ventilation, vascular tone and neurotransmitter release...

OBJECTIVES: To use a large administrative database to determine the mortality, risk factors, and co-morbidities of esophageal variceal bleeding in children. STUDY DESIGN: Retrospective cohort study using Pediatric Health Information System (PHIS) data from 50 tertiary children's hospitals in the US. ICD codes from 2004 through 2019 identified children 18 years and younger with variceal bleeding and complications. Univariate analyses used the Student t-test for continuous variables (age) and chi-square test for categorical variables (all others)...

Pannexin1 (Panx1) channels export ATP and may contribute to increased concentration of the vasodilator ATP in plasma during hypoxia in vivo. We hypothesized that Panx1 channels and associated ATP export contributes to hypoxic vasodilation, a mechanism that facilitates the matching of oxygen delivery to tissue metabolic demand. Male and female mice devoid of Panx1 (Panx1-/-) and wild-type controls (WT) were anesthetized, mechanically ventilated, and instrumented with a carotid artery catheter or femoral artery flow transducer for hemodynamic and plasma ATP monitoring during inhalation of 21% (normoxia) or 10% oxygen (hypoxia)...

This study aimed to investigate the hypothesis that vasopressin extends the anesthetic response time of lidocaine and does not affect the circulatory dynamics. Rats were sedated with isoflurane; subsequently, breathing was maintained through mechanical ventilation. We infiltrated the first molar area of the upper left jaw with saline (NS, test solution), 2% lidocaine (L), 0.025 IU vasopressin-supplemented 2% lidocaine, 0.05 IU vasopressin-supplemented 2% lidocaine, 0.1 IU vasopressin-supplemented 2% lidocaine, and 0...

Barotrauma is a commonly reported complication in critically ill patients with ARDS caused by different etiologies, it's rate is reported to be around %10. Pneumothorax/pneumomediastinum in COVID-19 patients seem to be more common and have different clinical characteristics. Here we report 9 patients who had pneumothorax and/or pneumomediastinum during their stay in the ICU. Patients who were admitted to ICU between March 2020 and December 2020, were reviewed for presence of pneumothorax, pneumomediastinum and subcutaneous emphysema during their ICU stay...
