Cytomegalovirus Retinitis: Current State in People with HIV-AIDS in Peru | Chapter 11 | New Insights into Disease and Pathogen Research Vol. 3

Purpose: To describe the incidence and progression of cytomegalovirus retinitis (CMVR) in public hospital patients from Peru.

Study Design:
Prospective study conducted in HIV-AIDS diagnosed patients.

Place and Duration of Study:
Department of Ophthalmology and Department of Tropical Medicine, Hospital Nacional Dos de Mayo, from 2004 to 2013.

Descriptive statistics were obtained for age, gender, associated disease, CMVR location and ganciclovir treatment. Data were analyzed by the Pearson Chi. Square test, Mann-Whitney test, and the two-tailed exact Fischer's Exact test. SPSS version 20.0 for Windows software program was used

2627 patients were evaluated, 75 had CMVR diagnosis. Active CMVR was found in 68 eyes (90.7%). Median age at diagnosis of CMVR was 37 years (IQR 30-41 years). Median CD4 level of 25 cells/μL (IQR 12.2-57.7 cells/μL), viral load > 1000,000 in 39 (52%) patients. Median mortality  rate was 7.1 deaths per 1000 PY and mean survival time from HIV diagnosis to death was 29,5 months (95%  8,7-43,0 months) and from CMVR diagnosis, 6,2 months (95%  IC 2,0-8,0 months). Duration since HIV diagnosis to CMVR onset was 12 months (IQR 3-48 months). Tuberculosis (TB) was present in 23 (30.7%) patients. Incidence rate of HIV patients with CMVR was 28.2 cases per 1000 PY. 51 patients received ganciclovir: endovenous 34 (91.17%), intravitreal 6 (26.5%) and orally 4 (11.8%).

CMVR has a high prevalence in young people with an elevated value of HIV-TB co-infection (30.7%). CMVR diagnosis was a predictor for early mortality, including highly active antiretroviral therapy (ART).

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)

Ethnopharmacological Survey among Traditional Medicine Practitioners in Abidjan (Côte d'Ivoire) for the Management of Pathologies such as Malaria, ENT Diseases, Diarrhea, Typhoid Fever and Anemia | Chapter 05 | New Horizons in Medicine and Medical Research Vol. 8

 Traditional Medicine Practitioners (TMPs) of Côte d'Ivoire are familiar with the therapeutic herbs. Medicinal plants have been shown to be useful in the treatment of common diseases such as malaria (KROA, 2004) and diabetes (N'GUESSAN et al, 2013) in several studies and scientific study. In the Abidjan District, the current policy is to integrate traditional medicine and pharmacopoeia into the national health system in order to improve population health coverage, particularly in the management of commonly encountered diseases such as malaria, ENT diseases, diarrhoea, typhoid fever, and anaemia. This research aims to increase the use of traditional medicine and pharmacopoeia in the national health system. Over the course of three months, fifty (50) PMTs in the District of Abidjan participated in this study. Plant therapists accounted for 30 of the 50 PMTs polled at the end of the study, or 60%. Traditional medicine centres use 61 types of medicinal plants from 36 famili
