Abstract

Importance: An intraoperative higher level of positive end-expiratory positive pressure (PEEP) with alveolar recruitment maneuvers improves respiratory function in obese patients undergoing surgery, but the effect on clinical outcomes is uncertain. Objective: To determine whether a higher level of PEEP with alveolar recruitment maneuvers decreases postoperative pulmonary complications in obese patients undergoing surgery compared with a lower level of PEEP. Design, Setting, and Participants: Randomized clinical trial of 2013 adults with body mass indices of 35 or greater and substantial risk for postoperative pulmonary complications who were undergoing noncardiac, nonneurological surgery under general anesthesia. The trial was conducted at 77 sites in 23 countries from July 2014-February 2018; final follow-up: May 2018. Interventions: Patients were randomized to the high level of PEEP group (n = 989), consisting of a PEEP level of 12 cm H2O with alveolar recruitment maneuvers (a stepwise increase of tidal volume and eventually PEEP) or to the low level of PEEP group (n = 987), consisting of a PEEP level of 4 cm H2O. All patients received volume-controlled ventilation with a tidal volume of 7 mL/kg of predicted body weight. Main Outcomes and Measures: The primary outcome was a composite of pulmonary complications within the first 5 postoperative days, including respiratory failure, acute respiratory distress syndrome, bronchospasm, new pulmonary infiltrates, pulmonary infection, aspiration pneumonitis, pleural effusion, atelectasis, cardiopulmonary edema, and pneumothorax. Among the 9 prespecified secondary outcomes, 3 were intraoperative complications, including hypoxemia (oxygen desaturation with Spo2 ≤92% for >1 minute). Results: Among 2013 adults who were randomized, 1976 (98.2%) completed the trial (mean age, 48.8 years; 1381 [69.9%] women; 1778 [90.1%] underwent abdominal operations). In the intention-to-treat analysis, the primary outcome occurred in 211 of 989 patients (21.3%) in the high level of PEEP group compared with 233 of 987 patients (23.6%) in the low level of PEEP group (difference, -2.3% [95% CI, -5.9% to 1.4%]; risk ratio, 0.93 [95% CI, 0.83 to 1.04]; P =.23). Among the 9 prespecified secondary outcomes, 6 were not significantly different between the high and low level of PEEP groups, and 3 were significantly different, including fewer patients with hypoxemia (5.0% in the high level of PEEP group vs 13.6% in the low level of PEEP group; difference, -8.6% [95% CI, -11.1% to 6.1%]; P

Abstract

Submerged arc welding (SAW) is a popular method of joining the metals. It gives greater protection to the welds from contamination from the external oxidation which is the main source for weakness of the weld. Also weld quality can be better controlled in the SAW by the control of weld speed, current, voltage and filler rod dimensions. But the weld formation on the parent metal is the key factor in generating the residual stress along with fatigue life of the joint. The proper insight of effect of weld formation in the joint is essential for better weld strength designs for longer life. Any weakness in the joint is the potential source for failure. The advent of finite element based numerical software, one can easily estimate the strength of joint using virtual simulation methods. In this work, the preparation and weld configuration effect on the residual stress formation due to SAW is carried out. [ABSTRACT FROM AUTHOR]

Abstract

Autonomous vehicles want reliable and strong sensor suites and alert systems. This paper discusses the composition and performance of a sophisticated monitoring and alert system for automobile vehicle parameters. The number of automobiles has also grown quickly to meet the enormous population. Additionally, this resulted in an increase in accidents. The accident prevention strategies now in use are all static and dated. Additionally, there is no reliable accident detection system. Automobile vehicle parameters are continuously monitored by a micro-controller which stores the data logs containing vehicle parameter data into a sheltered digital memory card and in the cloud storage. The system doesn't solely record the vehicle parameters data of the automobile periodically, but also actively monitors for any sudden vehicle accident detection. The sensor may facilitate folks to analyze the accident quickly and lawfully when a collision happens to alert the emergency services to that location. The system will update the information whenever an abnormal system event happens. A black box in a vehicle gather driving information about the vehicle before, during and after a crash. The data gathered includes, speed, acceleration, braking, steering and air-bag deployment. The Automotive black box system can aid with vehicle safety, increase collision victim care, assist insurance corporations with vehicle crash investigations, and improve road conditions to reduce death rates. According to experimental findings, the proposed technique achieves 29.3103%, 22.70 %, 18.103% and 11.206 % higher accuracy compared to RFID, SVM,CNN and RNN Methods.

Abstract

The hybrid operating room is the venue for transcatheter therapy with the convergence of three specialties: cardiac surgery, cardiovascular anesthesiology, and interventional cardiology. Transcatheter aortic valve replacement is proof that cardiac specialists have embraced the endovascular revolution. Since pharmacologic and ischemic myocardial conditioning are safe and effective, they are currently the focus of multiple trials. Angiotensin blockade, anemia and endoscopic saphenous vein harvesting worsen outcome after coronary artery bypass grafting (CABG). Although off-pump CABG is equivalent to on-pump CABG, it may improve outcomes in high-risk groups. Although percutaneous coronary intervention (PCI) significantly decreases mortality after myocardial infarction, the evidence is less convincing for intra-aortic balloon counterpulsation. Even though prasugrel was recently approved for platlet blockade in PCI, it may be superceded by ticagrelor. Although PCI and CABG appear equivalent for multivessel coronary disease, CABG lowers revascularization rates and also has superior outcomes in diabetics and the elderly. Hetastarch and N-acetylcysteine both increase bleeding and transfusion in cardiac surgery. Factor VII can treat life-threatening bleeding, but its safety requires further evaluation. Since eltrombopag and romiplostim stimulate platelet production, they may have a future role in hemostasis after cardiac surgery. Even though fenoldopam, atrial natriuretic peptide and sodium bicarbonate are nephroprotective, further trials must confirm these findings. Intensive insulin therapy offers no further outcome advantage and significantly increases hypoglycemic risk. The past year has witnessed the advent of a new clinical venue, new devices, and new drugs. The coming year will most likely advance these achievements.

Abstract

Healthcare is one of the application domains that use IoT technology, where sensors and IoT-enabled medical devices transmit data to healthcare specialists without the need for human intervention. The health records of previous patients are both very confidential and crucial to the identification of the disease for current patients. Therefore, it is important to fully utilize the records of previous patients without disclosing their personal data. This paper proposes an innovative Self Diagnosis Platform (SDP) that securely retrieves patients' records from past records without disclosing either the privacy of the patient or the record database. Initially, the patient device receives data from the sensors placed in the patient's body, which is then encrypted by using Edwards' Digital Signature Algorithm. The encrypted data is then sent to the Secure Disease Archive (SDA), which contains past records. Based on the patient's data, similar records will be retrieved from the database using the SDP. The suggested framework is compared with traditional methods in terms of encryption time, execution time, and end-to-end delay. Experimental results indicate that the suggested SDP technique achieves a better execution time of 30.63%, 27.48%, 22.07%, and 9.23% than LDQN, SE-AC, PMDA, and EPPDA methods. This system is more effectiveand secure for real-time applications.

CAPITAL requirements, ECONOMIC development
Abstract

Economic growth and sustainable development is not possible without the role of banking sector. Approximately more than 40% of the national savings deployed in bank deposits, so, the dependency on banking is consistently increasing day-to-day which ensures high risk-sensitivity for the banks to manage its financial obligations. Competition, market volatility, time liability etc., leads to financial crisis as an impact of under-estimation of risk. Countries like America and other developed nations had already experienced this. So a reactive measure should take to reinforce the stability of the financial system (especially banks). Consequently, concerned government and respective institutions entered with prudential norms (Banking Regulation) indulge a goal to ensure financial stability of individual institution and a safe and sound banking in order to protect the interest of the depositors and to promote healthy and stable investment environment in the financial system. In this backdrop, capital adequacy obligations possess critical role in augmenting the banks' efficacy. With the global co-ordination (G-10 countries), Basel I, a capital adequacy requirement formed by the Basel Committee on Banking Supervision (BCBS), under the auspices of the Bank for International Settlements (BIS). Due to the external environmental forces and economic shocks results strong amendments in the consequent years. At last, the Basel committee have proposed Basel III regime to ensure that financial institutions maintain sufficient capital and liquidity buffers. So, this study intended at exploring the forecasting capital requirements for Risk-Weighted Assets to meet complete Basel III compliance as per Reserve Bank of India. [ABSTRACT FROM AUTHOR]
