This study aims to evaluate the effects of a high-fat diet and mechanical ventilation on the pulmonary and systemic inflammatory response in C57BL/6 mice. Male C57BL/6 mice were divided into two groups: one received a standard diet, and the other received a high-fat diet. After 10 weeks, the groups were further divided into two groups each: control group (CG), mechanical ventilation group (MVG), diet group (DG), and diet mechanical ventilation group (DMVG). MVG and DMVG underwent mechanical ventilation for 60 minutes. All animals were euthanized for subsequent analysis. Animals receiving a high-fat diet presented higher body mass, adipose index, and greater adipocyte area. In the lung, the expression of HMGB1 was greater in DG and DMVG than in CG and MVG. CCL2 and IL-22 levels in MVG and DMVG were increased compared to those in CG and DG, whereas IL-10 and IL-17 were decreased. Superoxide dismutase activity was higher in MVG and DMVG than in CG. Catalase activity was lower in DG than in CG, and in MV groups, it was lower than that in CG and DG. MV and obesity promote inflammation and pulmonary oxidative stress in adult C57BL/6 mice.

Background: The rapid advancement of minimally invasive surgical techniques has made laparoscopy a preferred alternative because it reduces postoperative complications. However, inflating the peritoneum with CO2 causes a cranial shift of the diaphragm decreasing lung volume and impairing gas exchange. Additionally, CO2 absorption increases blood CO2 levels, further complicating mechanical ventilation when the lung function is already compromised.

Purpose: Diabetes mellitus (DM) is a well-established risk factor for postoperative complications. Distal radius fractures (DRFs) are a common orthopedic injury and often require open reduction and internal fixation (ORIF). The rise of ORIF utilization warrants investigation into factors that may expose patients to postoperative complications following DRF ORIF.

Intermediate care (IC) is prevalent nationwide, but little is known about how to best organize this level of care. Using a 99-item cross-sectional survey assessing four domains (hospital and physical IC features, provider and nurse staffing, monitoring, and interventions/services), we describe the organizational heterogeneity of IC within a five-hospital healthcare system. Surveys were completed by nurse managers from 12 (86%) of 14 IC settings.

Introduction: The understanding of the interaction of closed-loop control of ventilation and oxygenation, specifically fraction of inspired oxygen (FiO2) and positive end-expiratory pressure (PEEP), and fluid resuscitation after burn injury and acute lung injury from smoke inhalation is limited. We compared the effectiveness of FiO2, PEEP, and ventilation adjusted automatically using adaptive support ventilation (ASV) and decision support fluid resuscitation based on urine output in a clinically relevant conscious ovine model of lung injury secondary to combined smoke inhalation and major burn injury.
Methods: Sheep were subjected to burn and smoke inhalation injury under deep anesthesia and analgesia.

This study aimed to identify risk factors for noninvasive ventilation (NIV) failure in <30 weeks' gestation preterm neonates and compare morbidity in patients with and without NIV failure. This study included preterm neonates <30 weeks' gestation who received NIV support for respiratory distress syndrome (RDS). Demographic and clinical characteristics were compared between infants with and without NIV failure within the first 72 hours after birth.
