Predictors Of Retention Among Individuals With Hiv Initiating Antiretroviral Therapy In Ghana, Ivy Ama Okae Jan 2023

Predictors Of Retention Among Individuals With Hiv Initiating Antiretroviral Therapy In Ghana, Ivy Ama Okae

Walden Dissertations and Doctoral Studies

Abstract Managing HIV requires lifelong therapy. Retaining clients on lifelong therapeutic antiretroviral therapy (ART) ensures the suppression of viral replication and better health outcomes. The time of the start of ART management is also a factor in determining better health outcomes for persons living with HIV. This study examined the association between initiation criteria (treat all, Option B+, and CDC T-cell count < 500) and retention on ART at 12 months for 17,974 randomly selected clients in the Ghana Health Service's HIV patient electronic database. Analyses controlled for age, gender, educational status, alcohol use, treatment/adherence monitoring, and tuberculosis disease treatment. Bronfenbrenner's ecological systems theory guided the interpretation of the findings. Results shows that retention was positively associated with all treatment initiation criteria. Clients initiated with CD4 count ≤ 500 criteria seemed to be retained at 12 months on ART at a higher rate than initiation criteria based on Option B+ and treat all. The study results may contribute to positive social change by supporting CD4 testing for clients before initiation of ART to improve retention and ensure the availability and use of adherence counseling, no tuberculosis disease and its prevention, and low use of alcohol among people living with HIV. The results of this study may also provide opportunities for public health policy intervention efforts requiring a personalized, group-based approach to service delivery at the intrapersonal level, interconnected with interpersonal, meso, and meta factors at the community level.

Passive Earplug Including Helmholtz Resonators Arranged In Series To Achieve Broadband Near Zero Occlusion Effect At Low Frequencies, Kevin Carillo, Franck Sgard, Olivier Dazel, Olivier Doutres Jan 2023

Passive Earplug Including Helmholtz Resonators Arranged In Series To Achieve Broadband Near Zero Occlusion Effect At Low Frequencies, Kevin Carillo, Franck Sgard, Olivier Dazel, Olivier Doutres

Études primaires

The use of passive earplugs is often associated with the occlusion effect: a phenomenon described as the increased auditory perception of one's own physiological noise at low frequencies. As a notable acoustic discomfort, the occlusion effect penalizes the use and the efficiency of earplugs. This phenomenon is objectively characterized by the increase in sound pressure level in the occluded ear canal compared to the open ear canal. Taking inspiration from acoustic metamaterials, a new design of a three-dimensional printed “meta-earplug,” made of four Helmholtz resonators arranged in series, is proposed for achieving near zero objective occlusion effect measured on artificial …


Ultrahigh-Performance Liquid Chromatography–Tandem Mass Spectrometry Quantitation Of O-Cresol In Hydrolyzed Human Urine To Assess Toluene Exposure, Eric Langlois, Sébastien Gagné Jan 2023

Ultrahigh-Performance Liquid Chromatography–Tandem Mass Spectrometry Quantitation Of O-Cresol In Hydrolyzed Human Urine To Assess Toluene Exposure, Eric Langlois, Sébastien Gagné

Études primaires

Rationale

Toluene is a volatile organic compound used in domestic and industrial applications. The main routes of workplace exposure to toluene are inhalation and dermal contact. As toluene exposure can cause severe nervous system damage, its quantification is crucial to prevent occupational illness. Toluene is metabolized mainly as hippuric acid, S-benzylmercapturic acid and epoxides. These are rapidly converted to o-/p-cresol, which is then excreted in the urine as conjugated glucuronides and sulfates. o-Cresol and its conjugates can be chemically hydrolyzed to form free o-cresol, which can then serve as a urinary biomarker of toluene exposure. Current …
