BACKGROUND:Studies looking at the effect of hospital teaching status on septic shock related in-hospital mortality are *** aim of this study was to examine the effect of hospital teaching status on mortality in septic shock patients in the United ***:This was a retrospective observational study,using the Nationwide Emergency Department Sample Database(released in 2018).All patients with septic shock were *** sample logistic regression was performed to assess the impact of hospital teaching status on patient ***:A total of 388,552 septic shock patients were included in the *** average age was 66.93 years and 51.7%were *** of the patients presented to metropolitan teaching hospitals(68.2%)and 31.8%presented to metropolitan non-teaching *** shock patients presenting to teaching hospitals were found to have a higher percentage of medical comorbidities,were more likely to be intubated and placed on mechanical ventilation(50.5%vs.46.9%)and had a longer average length of hospital stay(12.47 d vs.10.20 d).Septic shock patients presenting to teaching hospitals had greater odds of in-hospital mortality compared to those presenting to metropolitan non-teaching hospitals(adjusted odd ratio[OR]=1.295,95%confidence interval[CI]:1.256-1.335).CONCLUSION:Septic shock patients presenting to metropolitan teaching hospitals had significantly higher risks of mortality than those presenting to metropolitan non-teaching *** also had higher rates of intubation and mechanical ventilation as well as longer lengths of hospital stay than those in non-teaching hospitals.

Hepatocellular carcinoma(HCC)is the most common primary tumor of the liver and often evolves from regenerating nodules in liver *** there have been significant advances in the treatment of HCC,the overall prognosis in patients with a large tumor burden,vascular invasion,or extrahepatic spread remains poor.1 The magnitude of liver stiffness in cirrhosis has been consistently associated with an increased risk of development of HCC.

Generalized Derivations in Rings with Involution

引用

Algebra Colloquium 2017年第3期24卷 393-399页

作者： Nadeem Ahmad Dar Abdul nadim Khan Department of Computer Science and Engineering Islamic University of Science and Technology J & K India Department of Mathematics Faculty of Science & Arts in Rabigh King Abdulaziz University Saudi Arabia

The main purpose of this paper is to study generalized derivations in rings with involution which behave like strong commutativity preserving mappings. In fact, we prove the following result： Let R be a noncommutative prime ring with involution of the second kind such that char（R） ≠ 2. If R admits a generalized derivation F ： R → R associated with a derivation d ： R → R such that [F（x）,F（x＊）] - [x,x＊] = 0 for all x ∈ R, then F（x）= x for all x ∈ R or F（x） = -x for all x ∈ R. Moreover, a related result is also obtained.

Implementation of quantum optical tristate oscillators based on tristate Pauli-X, Y and Z gates by using joint encoding of phase and intensity

引用

Optoelectronics Letters 2022年第11期18卷 673-677页

Oscillator circuit has the significant role to always repeat the same signal at the output after certain time interval. In quantum computing, intensity and phase of light signal can be made oscillatory at the output of a quantum optical oscillator circuit. In this paper, we have implemented quantum optical tristate oscillator circuits based on tristate Pauli-X, Y and Z gates using phase and intensity encoding technique of light signal. Here, three different oscillator circuits are developed. The phase of light signal is chosen as the oscillating parameter in all proposed circuits. The truth tables and oscillating phase diagrams are also shown for each oscillator circuit in this paper. The operation of one of the oscillator circuits is simulated with MATLAB to prove its feasibility.

Indolent lung opacity: Ten years follow-up of pulmonary inflammatory pseudo-tumor

引用

World Journal of Clinical Cases 2017年第2期5卷 61-66页

作者： Jad A Degheili nadim A Kanj Salwa A Koubaissi Mouhamad J Nasser Division of General Surgery Department of Surgery American University of Beirut-Medical Center Division of Pulmonary Critical Care and Sleep Medicine Department of Internal Medicine American University of Beirut-Medical Center Department of Internal Medicine American University of Beirut-Medical Center

Inflammatory pseudotumor(IPT) has always been considered a diagnostic challenge. Its rarity and resemblance to other more common pathological entities imposes that neither clinical nor radiological characteristics can lead to a definitive diagnosis. The surgical excision of the lesion is the ultimate approach for accurate diagnosis and cure. Moreover the true nature of IPT, its origin as a neoplastic entity or an overreactive inflammatory reaction to an unknown trigger, has been a long debated matter. Surgery remains the treatment of choice. IPT is mostly an indolent disease with minimal morbidity and mortality. Local invasion and metastasis predict a poor prognosis. We hereby present a unique case of pulmonary IPT that was surgically excised, but recurred contralaterally, shortly thereafter. Despite no medical or surgical treatment for ten years, the lesion has remained stable in size, with neither symptoms nor extra-pulmonary manifestations.
