Preperitoneal pelvic packing as a salvage operation for postoperative retroperitoneal bleeding with hemodynamic instability after the Kocher-Langenbeck approach to the acetabulum: a case report.

Pelvic fractures result from high-energy trauma, and when accompanied by hemorrhagic shock, the mortality rate increases to 40%. Pelvic fractures are anatomically categorized as pelvic ring disruptions and acetabular fractures, each requiring different treatment methods and approaches. Acetabular fractures, which also result from high-energy injuries, may be accompanied by hemorrhagic shock.

Solvent-Free Dry-Process Enabling High-Areal Loading Selenium-Doped SPAN Cathodes Toward Practical Lithium-Sulfur Batteries.

In this study, a selenium-doped sulfurized polyacrylonitrile (Se-SPAN) cathode fabricated by a dry process with multi-walled carbon nanotubes (MWCNT) and a polytetrafluoroethylene (PTFE) binder is proposed to address issues in currently developed dry-processed cathodes. The dry-processed Se-SPAN (D/Se-SPAN) is characterized by a dense, robust, and uniform structure that successfully resists the internal stress evolution caused by significant volume variations of the Se-SPAN under high-loading conditions. Understanding these architectural advantages in D/Se-SPAN, the unrivaled potential of D/Se-SPAN compared with traditional slurry-processed Se-SPAN cathodes (S/Se-SPAN) is established through a series of in-depth electrochemical-mechanical investigations.

Recent Increases in Influenza-Related Hospitalizations, Critical Care Resource Use, and In-Hospital Mortality: A 10-Year Population-Based Study in South Korea.

Background: Long-term trends in influenza-related hospitalizations, critical care resource use, and hospital outcomes since the 2009 H1N1 influenza pandemic season have been rarely studied for adult populations. Materials and Methods: Adult patients from the Korean Health Insurance Review and Assessment Service who were hospitalized with influenza over a 10-year period (2009−2019) were analyzed. The incidence rates of hospitalization, critical care resource use, and in-hospital death were calculated using mid-year population census data.

Association of pulmonary arterial pressure with volume status in patients with acute respiratory distress syndrome receiving extracorporeal membrane oxygenation.

Background: Data on pulmonary hemodynamic parameters in patients with acute respiratory distress syndrome (ARDS) receiving extracorporeal membrane oxygenation (ECMO) are scarce.

Methods: The associations between pulmonary artery catheter parameters for the first 7 days of ECMO, fluid balance, and hospital mortality were investigated in adult patients (aged ≥19 years) who received venovenous ECMO for refractory ARDS between 2015 and 2017.

Results: Twenty patients were finally included in the analysis (median age, 56.

Ratchet-integrated pneumatic actuator (RIPA): a large-stroke soft linear actuator inspired by sarcomere muscle contraction.

Pneumatic artificial muscles (PAMs) have a wide range of robotics applications, especially in soft robots, for their ability to generate linear force and displacement with the soft, lightweight, compact, and safe characteristics as well as high power densities. However, the compressibility of the air causes a spring-like behavior of PAMs, resulting in several common issues of limited stroke, load-dependent stroke lengths, difficulty in maintaining their length against disturbance, and necessity of accurate pressure control system. To address these issues, this study borrows inspiration from a biological soft linear actuator, a muscle, and proposes a ratchet-integrated pneumatic actuator (RIPA).

Validity of bone scans to detect missed injury in patients with major trauma.

Background: It is easy to miss injuries in patients with major trauma (MT). The authors hypothesized that bone scans (BSs) would reduce the number of missed injuries. However, there was not enough evidence on BS in patients with MT.

Risk factor of benign paroxysmal positional vertigo in trauma patients: A retrospective analysis using Korean trauma database.

Benign paroxysmal positional vertigo (BPPV) is a comorbid condition prevalent in patients recovering from trauma. Due to the paucity of studies investigating the etiology of this condition, the present study sought to analyze the high-risk group of BPPV patients following trauma.Trauma patients visiting the emergency department from January to December 2016 were enrolled.

Physical and nutrition statuses of geriatric patients after trauma-related hospitalization: Data from the Korean National Health and Nutrition Examination Survey 2013-2015.

Population aging is associated with increasing numbers of geriatric trauma patients, and various studies have evaluated their short-term outcomes, assessment, and treatment. However, there is insufficient information regarding their long-term outcomes. This study evaluated the physical and nutritional statuses of geriatric patients after trauma-related hospitalization.

Hyperchloremia is associated with 30-day mortality in major trauma patients: a retrospective observational study.

Background: Chloride is important for maintaining acid-base balance, muscular activity, osmosis and immunomodulation. In patients with major trauma, chloride levels increase after fluid therapy; this is associated with poor clinical outcomes. The purpose of this study was to determine whether hyperchloremia was associated with increased mortality in patients who had sustained major trauma.

Apicularen A acetate induces cell death via AIF translocation and disrupts the microtubule network by down-regulating tubulin in HM7 human colon cancer cells.

Apicularen A is a novel antitumor agent and strongly induces death in tumor cells. In this study, we synthesized apicularen A acetate, an acetyl derivative of apicularen A, and investigated its antitumor effect and mechanism in HM7 colon cancer cells. Apicularen A acetate induced apoptotic cell death and caspase-3 activation; however, the pan-caspase inhibitor Z-VAD-fmk could not prevent this cell death.
