Abstract Background A favorable neurological outcome is closely related to patient characteristics and total cardiopulmonary resuscitation (CPR) duration. The CPR duration consists of pre-hospital in-hospital durations. To date, consensus lacking on the optimal Therefore, this study aimed determine upper limit duration, cut-off time at level, switch from conventional alternative such as extracorporeal CPR. Methods We conducted a retrospective observational using prospective, multi-center...
DRAMs in modules are preferably arranged multiple ranks to increase system band-width. However, this limits the input/output (I/O) speed since increased channel loading causes degradation signal integrity. To overcome I/O limit, several buffered module solutions have been proposed, where data pins by additional chips. increases power consumption and latency significantly. We present a 3D DRAM with TSVs that overcomes of conventional approaches. Important architectural aspects, key...
Abstract Urinary stone size is key in determining treatment. Although computed tomography (CT) scans are widely used for diagnosing urinary stones, measurements of obtained from CT images may be inaccurate compared to actual size. Twenty-four phantoms were 3D printed at three densities (100, 1000, and 3000 Hounsfield units [HU]) eight sizes. the taken. Nineteen radiologists 33 emergency physicians two institutions measured sizes on using mediastinum bone settings. An automated algorithm...
The current diagnosis of bacteremia mainly relies on blood culture, which is inadequate for the rapid and quantitative determination most bacteria in blood. Here, a quantitative, multiplex, microfluidic fluorescence situ hybridization method (μFISH) developed, enables early (3-h) without need prior culture. This novel technology employs mannose-binding lectin-coated magnetic nanoparticles, effectively opsonize broad range pathogens, magnetically sequestering them device. Therein, μFISH...
It is not easy to ensure optimal prevention of hospital-acquired pressure ulcer (HAPU) in crowded emergency departments (EDs). We hypothesised that a prolonged ED length stay (LOS) associated with an increased risk HAPU. This single-centre observational study. Prospectively collected HAPU surveillance data were analysed. Adult (aged ≥20 years) patients admitted through the from April 1, 2013 December 31, 2016 included. The primary outcome was development within month. Covariates included...
Abstract Background Out-of-hospital cardiac arrest (OHCA) is a significant public health issue worldwide and associated with low survival rates poor neurological outcomes. The generation of optimal coronary perfusion pressure (CPP) via high-quality chest compressions key factor in enhancing rates. However, it often challenging to provide adequate CPP real-world cardiopulmonary resuscitation (CPR) scenarios. Based on animal studies human trials improving patients nontraumatic OHCA,...
Background Ischaemic tissue injury caused by hypoperfusion is one of the major consequences sepsis. Phosphate concentrations are elevated in ischaemic injury. This study was performed to investigate association phosphate with mortality patients Methods a retrospective cohort sepsis conducted at an urban, tertiary care emergency department (ED) Korea. Patients arriving between March 2010 and April 2017 were stratified into four groups according initial concentration presentation ED: group I...
Abstract Background In patients with out‐of‐hospital cardiac arrest (OHCA), low blood pressure after return of spontaneous circulation (ROSC) can be a sign hemodynamic instability. We aimed to investigate whether systolic (SBP) measured immediately ROSC is associated survival on admission. Methods Patients OHCA between 2015 and 2018 were included. The primary outcome was Included divided into three groups based the SBP at time ROSC: group 1 (SBP ≤90 mmHg), 2 90–120 3 >120 mmHg)....
Recent studies have suggested the existence of a blood microbiome in healthy host. However, changes upon bloodstream infection are not known. Here, we analyzed dynamics porcine model polymicrobial bacteremia induced by fecal peritonitis. Surprisingly, detected bacterial populations even before infection, and these were maintained over time. The native was notably taxonomically different from that used to induce peritonitis, reflecting microbial tropism for blood. Although population...
Abstract Background The selection of initial empirical antibiotics is an important issue in the treatment severe community-acquired pneumonia (CAP). This study aimed to investigate whether antibiotic prescription concordant with guidelines emergency department (ED) affects 30-day mortality patients CAP. Methods We conducted a retrospective analysis adult CAP who were hospitalized ED. Severe was defined according criteria 2007 Infectious Diseases Society America/American Thoracic guidelines....
Cerebral mitochondrial dysfunction during post–cardiac arrest syndrome (PCAS) remains unclear, resulting in a lack of therapeutic options that protect against cerebral ischemia–reperfusion injury. We aimed to assess the hippocampus after cardiac and whether vagus nerve stimulation (VNS) can improve neurological outcomes. In an asphyxial model, male Sprague–Dawley rats were assigned isolation (CA) or VNS (CA + VNS) group. Cardiopulmonary resuscitation was performed 450 s pulseless electrical...
The low survival rate of out-of-hospital cardiac arrest (OHCA) patients is a global public health challenge. We analyzed the relationship between number prehospital EMS personnel and admission, discharge, good neurologic outcomes in OHCA patients. This was retrospective observational study. Adult nontraumatic from January 1, 2015, to December 31, 2018, were included 12 cities Gyeonggi province, metropolitan area located suburbs capital Republic Korea. By comparing insufficient team (four or...
