Paraoxonase 1 is believed to play a role in preventing lipid oxidation and, thus, limiting production of proinflammatory mediators. Systemic inflammatory response in sepsis increases oxidative stress and decreases high-density lipoprotein (HDL) concentrations. The objective of this study was to investigate serum paraoxonase 1 activities in critically ill patients with sepsis and after recovery. Serum paraoxonase 1 arylesterase/paraoxonase activities, concentration of total cholesterol, HDL cholesterol (HDL-C) and serum C-reactive protein (CRP) in septic patients of a medical intensive care unit (n = 30) and age/sex-matched outpatient controls without sepsis (n = 30) were analyzed. Paired convalescent samples were also taken 1 week after recovery (n = 11). In septic patients, both arylesterase (88.3 +/- 36.5 vs. 162.1 +/- 44.8 kU/l, P < 0.001) and paraoxonase (75.2 +/- 50.0 vs. 125.2 +/- 69.4 U/l, P < 0.01) paraoxonase 1 activities decreased as compared to controls. Both activities normalized after recovery. Negative correlation was found between CRP and both arylesterase (r = -0.676, P < 0.001) and paraoxonase (r = -0.401, P < 0.01) as well as positive correlation between HDL-C and both arylesterase (r = 0.585, P < 0.001) and paraoxonase (r = 0.405, P < 0.01) paraoxonase 1 activities. The decreased activity of paraoxonase 1 in negative correlation with CRP offers a potentially useful marker of sepsis progress and recovery in critically ill patients.

Background: Acute kidney injury (AKI) is a common complication in critically ill patients, with approximately 5% requiring continuous renal replacement therapy (CRRT). This study investigated the relationship between mean arterial pressure (MAP) and 28- and 90-day mortality in critically ill AKI patients treated with CRRT.
Methods: This secondary analysis of a bicenter, retrospective, observational study included patients with AKI who were treated with CRRT from January 2009 to September 2016.

Background: Nutrition interventions commenced in ICU and continued through to hospital discharge have not been definitively tested in critical care to date. To commence a program of research, we aimed to determine if a tailored nutrition intervention delivered for the duration of hospitalisation delivers more energy than usual care to patients initially admitted to the Intensive Care Unit (ICU).
Methods: A multicentre, unblinded, parallel-group, phase II trial was conducted in twenty-two hospitals in Australia and New Zealand.

Background: A lung cancer diagnosis has a huge impact on the psychological well-being of both patients and family caregivers. However, the current psychological stress status among dyads remains unclear. We aimed to determine the prevalence of anxiety and depression and identify the factors that influence patients with lung cancer and their caregivers.

Background: Along with lung volume reduction surgery (LVRS), bronchoscopic lung volume reduction is a treatment option for end-stage emphysema. However, comparisons among interventions remain insufficient.
Methods: We searched on PubMed, CENTRAL, Embase, and Web of Science.

Introduction: Cardiac arrest (CA), characterized by its heterogeneity, poses challenges in patient management. This study aimed to identify clinical subphenotypes in CA patients to aid in patient classification, prognosis assessment, and treatment decision-making.
Methods: For this study, comprehensive data were extracted from the Medical Information Mart for Intensive Care IV (MIMIC-IV) 2.
