The Glutathione S-Transferase Activities in the Evaluation Acute Viral Hepatitis B and Chronic Alcoholic Liver Disease | Chapter 04 | New Insights into Disease and Pathogen Research Vol. 3

Glutathione S-Transferase is an important hepatic detoxifying enzyme. Half-life of GST alpha in plasma is about 1 hr; its concentration follows the changes in the hepatocellular damage more rapidly than aspartate amino transferase (AST) or alanine amino transferase (ALT).

Aim and Objectives: To validate chronic alcoholic liver disease and acute viral hepatitis B could produce any significant changes in serum glutathione S-transferase activities.

Materials and Methods: A total of 120 samples were used in the present research. 20 hepatitis B patient 40 chronic alcoholic hepatitis patients and 60 age and sex matched control subjects. Serum GST activity and standard LFT (Liver Function Test) parameters done.

Results: GST activity showed a significantly increase (p value< 0.001) in chronic alcoholic liver disease patients (22.293±4.159 IU/L vs 20.127±4.789 IU/L) and in acute viral hepatitis (23.685±6.751 IU/L vs 20.127±4.789 IU/L). In multiple logistic regression analysis when GST measurement was added to a LFT, the diagnostic significance increased from R2=0.792 to 0.884 in acute viral hepatitis B and from R2= 0.843 to 0.849 in chronic alcoholic cirrhosis. Standard LFT parameters are significantly different in both groups. Area under ROC (Receiver Operative Characteristic Curve) is 0.952 for model having albumin+ ALT which is increased to 0.992 after addition of GST in previous model in acute viral Hepatitis B. While in alcoholic Hepatitis Area under ROC is 0.966 for model having albumin+ ALT which is increased to 0.974 after addition of GST in previous model.

Conclusion: GST activity may provide additional LFT measurement to the current battery of tests to differentiate acute hepatitis B and alcoholic liver disease from normal population and may improve the evaluation of Hepatitis B virus and alcoholic cirrhosis when added to routine LFT parameters.

A Prospective Study about Safety and Efficacy of Perioperative Lidocaine Infusion | Chapter 09 | New Horizons in Medicine and Medical Research Vol. 8

 Opioids cause clinically significant side effects such as respiratory depression, immunosuppression, muscle rigidity, negative inotropism, nausea, vomiting, hyperalgesia, urine retention, postoperative ileus, and drowsiness. Perioperative opioids are a major contributor to the United States' and other countries' opioid epidemics. Non-opioid analgesics, particularly lidocaine, are becoming more common for perioperative use as a result of this. A total of 185 adult patients were randomly assigned to one of two groups: control group I (105 patients) [fentanyl group] or group ii (80 patients) [opioid-free anaesthesia group]. Lidocaine 1.5 mg/kg bolus followed by 1.5 mg/kg/h infusion intraoperatively, and 1.5-2 mg/kg/h infusion for 2-8 hours postoperatively were given to patients in both groups at anaesthetic induction. Intraoperatively, both groups received analgesic adjuvants such as diclofenac 75 mg, paracetamol 1 gm, and mgso4 30-50 mg/kg. If the mean arterial pressure (map)

A Brief Study of Middleware Technologies: Programming Applications and Management Systems | Chapter 15 | Novel Research Aspects in Mathematical and Computer Science Vol. 1

  Many platforms, services, applications, hardware, and operating systems are connected through the middleware layer. Because the middleware layer abstracts much low-level complexity and makes applications and software systems portable, it allows disparate systems to interface and function together in harmony. Middleware technologies enable software engineers to swiftly construct software systems and applications, allowing developers to focus on more important tasks. This chapter examines several types of middleware systems and discusses middleware capabilities, middleware operation, middleware's function in cloud-based systems, and the best middleware platforms to use. Middleware systems are widely utilised and can be found in practically any software system or application. Middleware programmes provide as a link between many sorts of systems and protocols. They serve as a mechanism for various systems. To successfully exchange information, it runs on a variety of operating system

Patients’ Perspective of Acute Post-operative Pain Management: A Multicentre Survey of Tertiary Hospitals in Maharashtra, India | Chapter 08 | New Horizons in Medicine and Medical Research Vol. 8

 When postoperative pain is adequately controlled, patients' satisfaction and patient-related outcomes (PROs) increase. Understanding the patients' perspective is crucial since it supports in the formulation of improvement strategies. Because wrong attitudes and assumptions might block pain alleviation, patients' attitudes and beliefs are critical. As a result, a multicenter study of patients' attitudes, beliefs, experiences, and satisfaction levels with acute postoperative pain management was done in Maharashtra's tertiary hospitals. In addition, the responses were examined to evaluate if the Acute Pain Service (APS) resulted in improved patient outcomes and satisfaction. A 13-item questionnaire adapted from previous studies was used to capture patients' experiences with postoperative pain treatment. The responses of 179 patients are included in the study. The findings revealed that 91.6 percent of patients experienced postoperative pain, with 75.5 percent
