This paper considers the proposal, development and numerical simulation of a system that models the behavior of the treatment of HIV-1 using antiretrovirals. The system defined for three dependent variables of the variable t, denoted by X(t)=(x1 (t), x2 (t), x3 (t)) represent the amount of T Lymphocytes "Helpers" (CD4), number of Cytotoxic T Lymphocytes (CD8) Viral load and infection process of HIV-1 at any time t, respectively. The assembly consists of a Nonlinear Ordinary Differential Equations system whose existential domain represents time system evaluation process of infection and viral clearance in a patient with HIV-1. This set of states of Nonlinear Dynamic System, associated with the initial value condition is called Cauchy problem. There are few studies related to the solution of this system, found some of the study are reduced to two variables and others without obtaining the ...

Objective: To analyze the operational management of the infection control plan (ICP) for tuberculosis in hospital care settings in a city with a high burden of the disease. Methods. An analysis of operational management was conducted in 37 institutions providing health services in the city of Cali, by applying a tool to collect information on the implementation of administrative, environmental and respiratory protection control measures. Additionally, the program design evaluation was conducted. Results: Administrative control measures were not implemented in 65 % of the institutions, primarily due to the absence of written infection control plans and a lack of risk assessment. 70 % of institutions failed to comply with environmental measures, especially in the verification of air flows, while respiratory control was well implemented in 78. However, the absence of ft testing for N95 resp...

Antimicrobial resistance (AMR) is an additional slow-evolving pandemic that precedes the COVID-19 pandemic and will continue when it ends. However, in countries such as Peru where there is high consumption and inadequate prescription of antibiotics, a more challenging future scenario can be expected. Antimicrobial Stewardship Programs (ASP) are multidisciplinary teams of professionals that aim to contain the emergence of multidrug-resistant organisms through strategies such as audit of antibiotic prescription or creating antibiotic treatment guidelines based on local AMR rates. The difficulty in the timely diagnosis of co-infections or superinfections in the clinical course of COVID-19 leads to inappropriate use of antibiotics, forcing ASP to adapt their strategies in this changing scenario. In Latin America, ASP not only has to promote behavior change in antibiotic prescribers but also ...

Objective: To assess the effectiveness and safety of hydroxychloroquine (HCQ) prophylaxis for the prevention of SARS-CoV-2 infection in healthcare workers (HCW) on duty during the COVID-19 pandemic. Results: A total of 68 HCWs met the eligibility criteria were randomly allocated to receive HCQ (n = 36) or not (n = 32). There were no significant differences between groups in respects to age, gender, or medical history. Eight participants met the primary efficacy endpoint of SAR-CoV-2 infection during the study period; there was no difference in incidence of SARS-CoV-2 infections between both study arms (HCQ: 5 vs Control: 3, p = 0.538). The relative risk of SARS-CoV-2 infection in the HCQ arm was 1.69 compared to the control group (95%CI 0.41–7.11, p = 0.463); due to poor participant accrual, the resulting statistical power of the primary efficacy outcome was 11.54%.

A prospective study of two groups of fifty patients each were conducted. The objective was to evaluate the use of antibiotics in vaginal hysterectomy for the prevention of vaginal infections dome. The selection was ramdomnizada forming independent samples under established criteria. The study group received an intravenous cephalothin sodium gram before entering the operating room and then two more doses at intervals of six hours. The control group received nothing. In analyzing the results, we see that there was not a single case of infection in both groups dome, both the study and control groups. Applying the test "T" statistical significance for studying the contrast of two independent samples, we can say that the administration of antibiotics is not necessary in these cases. The vaginal preparation in the pre-operative is fundamental.
