Neurocognitive Impairment In People Living With Human Immunodeficiency Virus (Hiv): Risk Factors And Mortality, Zaeema Naveed

Theses & Dissertations

Despite the widespread use of combination antiretroviral therapy (cART), HIV-associated neurocognitive impairment (NCI) persists in people living with HIV (PLWH) with clinical and public health implications. Studies have generated inconsistent results regarding etiological factors for NCI in PLWH and a brief user-friendly predictive tool is desirable in clinical practice to assess the probability of having NCI in PLWH. Furthermore, factors associated with clinically meaningful decline in neurocognitive status and survival disadvantage for patients with NCI are understudied in the post-cART era. The goal of this dissertation was to investigate factors associated with baseline NCI and neurocognitive decline and the association …

The Impact Of Rural-Urban Residency On Colorectal Cancer Screening, Stage At Diagnosis And Treatment In The Privately Insured Population, Mesnad Alyabsi

Colorectal Cancer (CRC) is the third most common and leading cause of cancer death in the United States. Although CRC screening can prevent and detect CRC at an early stage, about 35% of Americans are not screened. Despite the recent increase in screening, people with lower SES and those who live in rural areas have lowest screening. In rural areas, a common obstacle for screening is the long trips for health services which is associated with advanced CRC.

Moreover, surgery is a substantial part of CRC treatment since stages I-III and some metastatic CRC (mCRC) patients are treated with surgery. …

Predictors Of Compliance And Predictive Values Of The Breast Cancer Screening Program Of The Oman Cancer Association (2009-2016), Sultan Al Balushi

Capstone Experience

Background: Most breast cancers in Oman are diagnosed at advanced stages and therefore early detection is important. The Oman Cancer Association (OCA) initiated a mobile mammography program in 2009 but no studies have evaluated the impact of the program. This study aimed to estimate the proportion of OCA-screened women who had repeated mammography (compliance) and the associated predictors. The sensitivity and specificity of the program were also evaluated.

Methods: Data for 13,079 women screened in the mammography clinic of OCA from 2009-2016 and medical records of all breast cancer patients seen at Royal and Sultan Qaboos University hospitals during the …
