Trends in Substance Use, Treatment as Prevention, and Resilience among Vulnerable Communities
Forty years after its discovery, the trajectory of health outcomes for people living with HIV (PWLH) has greatly improved, although the demographic of individuals affected by HIV has shifted. This dissertation aimed to 1) characterize a population of women experiencing homelessness (WEH) and unstable housing and the trends of their polysubstance use and mental health symptoms, 2) examine the association of time-varying, cumulative prescription opioid use with higher odds of detectable viral load among cohorts of men and women living with HIV, and 3) examine the associations between resilience factors and adherence among a population of Black women living with HIV (BWLWH). Analyses included latent class analysis and latent class regression (Aim 1), mixed effects modeling (Aim 2), and network analysis (Aim 3). The first paper used data from the Polysubstance Use and Health Outcomes Evaluation (PULSE) study, a prospective cohort study of WEH in San Francisco, CA. The second paper used data from the MACS/WIHS Combine Cohort Study (MWCCS), a longitudinal study that aims to examine health outcomes among PLWH. The third paper used data from the Striving Towards EmPowerment and Medication Adherence (STEP-AD) study, an RCT aimed at improving adherence among BWLWH. Results from the three separate studies found that 1) among WEH, there are distinct groups of women who report using cocaine, painkillers, and experiencing stress; 2) among men and women in the MACS and WIHS cohorts, odds of having detectable viral load were increased for Black women in particular; and 3) self-efficacy is an important resilience factor for BWLWH. These findings highlight both women's health and the intersectionality that many women experience. It is the hope that these findings will inform future interventions aimed at improving women's HIV-related health outcomes, such as stress, trauma, and self-efficacy, as well as finding possible alternatives to prescription opioid treatment.</p
Is Nottingham Health Profile a reliable tool to measure quality of life of Filipinos with chronic kidney diseases undergoing hemodialysis.
The quality of life (QOL) of hemodialysis patients is often compromised and many tools have been developed to assess the health-related QOL of chronic kidney disease (CKD) patients undergoing hemodialysis. However, no such tool is currently in use in the Philippines. The objective of this study is to determine if Nottingham Health Profile (NHP) can be a useful tool in the Philippines. Eighty patients undergoing hemodialysis in the dialysis unit of our hospital were enrolled for this study. Sixty-nine patients completed the study. Comparative analysis revealed significant difference in social isolation with favorable result for the Filipino patients. Other measures correlate well although with differences that were not statistically significant. NHP can be successfully applied as a standard QOL tool in the Philippines. However, it should be translated into Filipino to avoid language difficulty. NHP may be recommended for QOL determination in other developing countries
Chronic Respiratory Disease and Health-Related Quality of Life of African American Older Adults in an Economically Disadvantaged Area of Los Angeles
Background. Most of the attention of policy makers, program planners, clinicians, and researchers in the area of physical health disparities among African American older adults has been traditionally focused on cardiometabolic disease and cancer. Among a long list of chronic medical conditions, chronic respiratory conditions (CRCs), such as asthma, chronic bronchitis, and emphysema, have received less attention. Purpose. This study investigated whether CRCs contribute to physical and mental health-related quality of life (HRQoL) of African American older adults who live in economically disadvantaged urban areas, and whether these effects are due to demographic factors, socioeconomic status (SES), health behaviors, and comorbid medical and mental conditions. Methods. This community-based study recruited 617 African American older adults (age ≥ 65 years) from Service Planning Areas (SPA) 6, an economically disadvantaged area in South Los Angeles. Structured face-to-face interviews were used to collect data on demographic factors (age and gender), SES (educational attainment and financial difficulty), living arrangements, marital status, health behaviors (cigarette smoking and alcohol drinking), health (CRC, number of comorbid medical conditions, depressive symptoms, and pain intensity), and physical and mental HRQoL (Physical and Mental Component Summary Scores; PCS and MCS; SF-12). Linear regressions were used to analyze the data. Results. The presence of CRCs was associated with lower PCS and MCS in bivariate analysis. The association between CRCs and PCS remained significant above and beyond all confounders. However, the association between CRCs and MCS disappeared after controlling for confounders. Conclusion. For African American older adults living in economically disadvantaged urban areas, CRCs contribute to poor physical HRQoL. Evaluation and treatment of CRCs in African American older adults may be a strategy for reduction of disparities in HRQoL in this population. As smoking is the major modifiable risk factor for CRCs, there is a need to increase accessibility of smoking cessation programs in economically disadvantaged urban areas. More research is needed on the types, management, and prognosis of CRCs such as asthma, chronic bronchitis, and emphysema in African American older adults who reside in low-income and resource limited urban areas
Blunt Trauma Abdominal and Pelvic Computed Tomography Has Low Yield for Injuries in More Than One Anatomic Region
Introduction: Most trauma centers order abdominal and pelvic computed tomography (CT) as an automatically paired CT for adult blunt trauma evaluation. However, excessive CT utilization adds risks of excessive exposure to ionizing radiation, the need to work up incidental findings (leading to unnecessary and invasive tests), and greater costs. Examining a cohort of adult blunt trauma patients that received paired abdominal and pelvic (A/P) CT, we sought to determine the diagnostic yield of clinically significant injuries (CSI) in the following: 1) the abdomen alone; 2) the pelvis alone; 3) the lumbosacral spine alone; and 4) more than one of these anatomic regions concomitantly.
Methods: In this retrospective study, we reviewed the imaging and hospital course of a consecutive sample of blunt trauma activation patients older than 14 years of age who received paired A/PCT during their blunt trauma assessments at an urban Level I trauma center from April through October 2014. Categorization of CSI was determined according to an a priori, expert panel-derivedclassification scheme.Results: The median age of the 689 patients who had A/P CT was 48 years old; 68.1% were male; 64.0% were admitted, and hospital mortality was 3.6%. CSI yields were as follows: abdomen 2.2% (95% confidence interval [CI] [1.3-3.6%]); pelvis 2.9% (95% CI [1.9-4.4%]); lumbosacral spine 0.6% (95% CI [0.2-1.5%]); both abdomen and pelvis 0.3% (95% CI [0.1-1.1%]); both the abdomen andlumbosacral spine 0.6% (0.2-1.5%); both the pelvis and lumbosacral spine 0.1% (0.0-0.8%); all three regions – abdomen, pelvis and lumbosacral spine – 0.1% (0.0-0.8%).Conclusion: Automatic pairing of A/P CT has very low diagnostic yield for CSI in both the abdomenand pelvis. These data suggest a role for selective CT imaging protocols that image these regions individually instead of automatically as a pair

Housing Instability Associated with Return to Stimulant Use among Previously Abstaining Women
Stimulant use among unstably housed individuals is associated with increased risks of psychiatric co-morbidity, violence, HIV transmission, and overdose. Due to a lack of highly effective treatments, evidence-based policies targeting the prevention of stimulant use disorder are of critical importance. However, little empirical evidence exists on risks associated with initiating or returning to stimulant use among at-risk populations. In a longitudinal cohort of unstably housed women in San Francisco (2016-2019), self-reported data on stimulant use, housing status, and mental health were collected monthly for up to 6 months, and factors associated with initiating stimulants after a period of non-use were identified through logistic regression. Among 245 participants, 42 (17.1%) started using cocaine and 46 (18.8%) started using methamphetamine. In analyses adjusting for demographics and socio-structural exposures over the preceding month, experiencing street homelessness was associated with initiating cocaine use (AOR: 2.10; 95% CI: 1.04, 4.25) and sheltered homelessness with initiating methamphetamine use (AOR: 2.57; 95% CI: 1.37, 4.79). Other factors-including race, income, unmet subsistence needs, mental health, and treatment adherence-did not reach levels of significance, suggesting the paramount importance of policies directed toward improving access to permanent supportive housing to prevent stimulant use among unstably housed women
