Post Exposure Prophylaxis for Occupational and Non-occupational Exposures to HIV: A 14-year Cohort Study in Lagos, Nigeria | Chapter 13 | New Insights into Disease and Pathogen Research Vol. 3

Background: Preventing new HIV infections among individuals is a major strategy to fight the HIV/AIDS scourge worldwide. In addition to the availability and use of highly active antiretroviral therapy to treat infections, short term treatment options to curtail the spread of potential infection of the virus in exposed individuals has been instituted. The various modes of exposure to the HIV virus and the risk of infection have been categorized with corresponding treatment options.

Aim: To evaluate the nature of exposure, time of presentation for treatment, adherence to follow up visits, treatment outcome and identify gaps of treatment procedures in a HIV treatment centre.

Study design: A retrospective cohort study.

Place and duration of study: The HIV treatment centre domiciled at the Clinical Sciences Department of the Nigerian Institute of Medical Research, Lagos, Nigeria from January 2006 to September 2019.

Methodology: A database retrospective review was conducted for adult patients who were treated for post exposure prophylaxis during the study period. A total of 422 patients whose records met the inclusion criteria were reviewed. Data were analyzed and presented using descriptive statistics.

Results: The mean age of the patients was 31.5 ± (10.1) years and higher proportions of the age group were <30 years (52.1%). Majority were females (71.6%), single (63%), had tertiary level of education (68.5%), were employed (70.6%) and had high risk exposures (76.3%). The most commonly prescribed regimen was LPV/r +AZT/3TC (56.2%).More than half (65.9%) had non-occupational exposures and overall, 97.2% presented for treatment within 72hours of exposure but only1.6% completed the follow up visits.

Conclusion: Treatment outcome appears good because no sero-conversion was reported or recorded. The younger age group had higher incidence of rape which was mainly among students which calls for urgent attention. There was a high incidence of needle stick injury among health care workers. There is a need to devise strategies to encourage completion of follow up visits.

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

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)

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
