Introduction: HIV, the human immunodeficiency virus. is.the etiological agent of acquired immunodeficiency s.ndrome (AIDs.. The aim of this.s.udy was.to as.es. the evolution of the viral load in patients.under treatment. methodology: This.was.a s.udy carried out from July 2017 to June 2022 at the Point G Univers.ty Hos.ital laboratory. The determination of the viral load of patients.was.carried out by PCR on the ABOTT m2000s./rt platform. Res.lts. A total of 129 patients.infected with HIV-1, aged 19 to 72 years.with a mean age of 40.05 years.± 10.71;all on antiretroviral chemotherapy. The female gender predominated among our patients. The mos. common treatment regimen was.2INTI + 1INNTI with 72.9% followed by 2INTI + 1INI with 13.2%. As.for the combinations.of molecules. the combination TDF + 3TC + EFV and TDF + 3TC + DTG predominated, res.ectively 65.1% and 13.2%. 89.9% of our patients.had undetectable viremia after 12 months.of treatment (p m 681315.65 copies.ml ± 1616908.484 to m0 at 5742.36 copies./ml ± 35756.883 at m12 (p Conclus.on: Generally s.eaking, antiretroviral treatment had contributed to controlling viral loads. however the therapeutic combination TDF + 3TC + DTG had made it pos.ible to obtain more patients.with undetectable viremia ins.ead.

The s.art Grid is.an enhancement of the traditional grid s.s.em and employs.new technologies.and s.phis.icated communication techniques.for electrical power trans.is.ion and dis.ribution. The s.art Grid’s.communication network s.ares.information about s.atus.of its.s.veral integrated IEDs.(Intelligent Electronic Devices.. However, the IEDs.connected throughout the s.art Grid, open opportunities.for attackers.to interfere with the communications.and utilities.res.urces.or take clients. private data. This.development has.introduced new cyber-s.curity challenges.for the s.art Grid and is.a very concerning is.ue becaus. of emerging cyber-threats.and s.curity incidents.that have occurred recently all over the world. The purpos. of this.res.arch is.to detect and mitigate Dis.ributed Denial of s.rvice [DDos. with application to the Electrical s.art Grid s.s.em by deploying an optimized s.ealthwatch s.cure Network analytics.tool. In this.paper, the DDos.attack in the s.art Grid communication networks.was.modeled us.ng s.ealthwatch tool. The s.mulated network cons.s.ed of s.cure Network Analytic tools.virtual machines.(Vms., electrical Grid network communication topology, attackers.and Target Vms. Finally, the experiments.and s.mulations.were performed, and the res.arch res.lts.s.owed that s.ealthwatch analytic tool is.very effective in detecting and mitigating DDos.attacks.in the s.art Grid s.s.em without caus.ng any blackout or s.utdown of any internal s.s.ems.as.compared to other tools.s.ch as.GNs., Nes.i2, NIs.T Framework, OmNeT++, INET Framework, Reas., Ns., Ns., m5 s.mulator, OPNET, PLC & TIA Portal management s.ftware which do not have the capability to do s..
