Despite recent advances in surgical techniques and endovascular devices, the management of ruptured type B aortic dissection remains challenging. Herein, we describe a patient with a history of chronic type B aortic dissection who presented to the emergency department with a massive left hemothorax and profound shock. Computed tomography demonstrated a thoracic dissecting aneurysm with false-lumen rupture. He underwent emergent thoracic endovascular aortic repair and carotid-carotid crossover bypass in a hybrid operating room...

Acute limb ischemia (ALI) is associated with high morbidity and mortality rates, even with the advent of technical advances. Although myocardial infarction is one of the causes of ALI along with intraventricular thrombus formation and subsequent embolism, ALI with concomitant acute myocardial infarction (AMI) is extremely rare. Here, we report a complicated ALI case with concurrent AMI and prolonged limb ischemic duration. The cause may be attributed to thrombosis with atherosclerotic disease of the coronary and peripheral arteries triggered by dehydration...

This paper presents the design, fabrication, and characterization of Schottky erbium/silicon photodetectors working at 1.55 µm. These erbium/silicon junctions are carefully characterized using both electric and optical measurements at room temperature. A Schottky barrier ΦB of ~673 meV is extrapolated; the photodetectors show external responsivity of 0.55 mA/W at room temperature under an applied reverse bias of 8 V. In addition, the device performance is discussed in terms of normalized noise and noise-equivalent power...

The generation and recombination of charge carriers in semiconductors through photons controls photovoltaic and light-emitting diode operation. Understanding of these processes in hybrid perovskites has advanced, but remains incomplete. Using femtosecond transient absorption and photoluminescence, it is observed that the luminescence signal shows a rise over 2 ps, while initially hot photogenerated carriers cool to the band edge. This indicates that the luminescence from hot carriers is weaker than that of cold carriers, as expected from strongly radiative transitions in direct gap semiconductors...

BACKGROUND: Large imaging systems in hybrid operating rooms are increasingly utilised. However, the effect of these ceiling mounted imaging systems on the air quality during ongoing surgical procedures has not yet been studied. The aim of this study is to evaluate the level of CFU/m3 near the surgical wound and near the instrument table during surgery. METHODS: Measurements were performed in 4 hybrid operating rooms at 4 different hospitals. During surgical procedures, at least 3 samples were taken with active slit air samplers...

DNA- and MNAzymes are nucleic acid-based enzymes (NAzymes), which infiltrated the otherwise protein-rich field of enzymology three decades ago. The 10-23 core NAzymes are one of the most widely used and well-characterized NAzymes, but often require elevated working temperatures or additional complex modifications for implementation at standard room temperatures. Here, we present a generally applicable method, based on thermodynamic principles governing hybridization, to re-engineer the existing 10-23 core NAzymes for use at 23 °C...

Transesophageal echocardiography (TEE) provides real-time information on both morphology and hemodynamics without radiation exposure or contrast media, interruption of surgical procedures, or need for transferring the patient to other division, and thus can be used as intraoperative monitoring as well as diagnostic imaging. TEE is helpful for confirming the adequacy of routine surgical procedures, ruling out an occurrence of unexpected adverse events, or even navigating the manipulations of cannulae and catheters...

Perovskite light-emitting field-effect transistors (PeLEFETs) provide a versatile device architecture to control transport and electroluminescence properties of hybrid perovskites, enabling injection of high charge carrier density and spatial control of the radiative recombination zone. Ionic screening and organic cation polarization effects typical of metal-halide perovskites, however, critically affect PeLEFET efficiency and reliability. In this work, we demonstrate a new device operation mode based on high-frequency modulation of the applied voltages, which allows significant reduction of ionic drift/screening in methylammonium lead iodide light-emitting transistors...

Symptomatic aortic stenosis remains a surgical disease, with aortic valve replacement resulting in symptom reduction and improvement in survival. For patients who are deemed a higher surgical risk, Transcatheter aortic-valve replacement (TAVR) is a viable, less invasive and increasingly common alternative. The study compares early outcomes in patients treated within one year of the commencement of TAVR program in a community hospital against outcomes of TAVR patients from nationwide reported data (Society of Thoracic Surgeons/ American College of Cardiology TVT registry)...

The fabrication of high-performance solid-state silicon quantum-devices requires high resolution patterning with minimal substrate damage. We have fabricated room temperature (RT) single-electron transistors (SETs) based on point-contact tunnel junctions using a hybrid lithography tool capable of both high resolution thermal scanning probe lithography and high throughput direct laser writing. The best focal z-position and the offset of the tip- and the laser-writing positions were determined in situ with the scanning probe...

Hierarchical SnO₂ nanocrystallites aggregates (NAs) were prepared with a simple room temperature⁻based aqueous solution method followed by simple freeze-drying treatment. The as-prepared SnO₂ NAs were subsequently combined with SnO₂ nanosheet⁻based structures from the viewpoint of a function-matching strategy, and under an optimized condition, a power conversion efficiency (PCE) of 5.59% was obtained for the resultant hybrid photoanode, a remarkable 60% enhancement compared to that of dye-sensitized solar cells (DSCs) fabricated with bare SnO₂ NAs architecture...

BACKGROUND: Acute care surgery (ACS) was proposed to address a general surgery workforce crisis; however, the ACS workforce composition is unknown. A national survey was conducted to determine the differences in the emergency general surgery (EGS) workforce between ACS and non-ACS hospitals. METHODS: The American Hospital Association (AHA) Annual Survey of Hospitals database was queried to identify acute care general hospitals. A hybrid mail/electronic survey was sent to 2811 acute care hospitals that met the inclusion criteria of hospitals that care for adult patients (≥18 years old) with an emergency room (ER), ≥ 1 operating room (OR), and 24-h ER access...

The hybrid emergency room (hybrid ER) system was first established in 2011 in Japan. It is defined as an integrated system including an ER, emergency computed tomography (CT) and interventional radiology (IVR) rooms, and operating rooms. Severe trauma patients can undergo emergency CT examinations and therapies (surgeries) without being transferred. The hybrid ER system is attracting attention because trauma resuscitation using this system has been reported to potentially improve the mortality rate in severe trauma patients...

BACKGROUND: Preoperative computed tomography (CT)-guided dye localization is essential for the surgical treatment of small lung nodules and is mostly performed by radiologists in the CT room. Several studies reported their early experiences of preoperative localization in the hybrid operating room. A comparison between localization in the CT room and hybrid room has not been reported. Therefore, we compared the outcomes of preoperative localization in the hybrid and CT rooms. METHODS: This study included patients who underwent preoperative CT-guided dye localization for thoracoscopic lung tumor surgery in the hybrid operation room (n = 25) and CT room (n = 283) at our institute...
