Non-Alcoholic Fatty Liver Disease And Metabolic Syndrome: The Role Of Gender Differences And Menopausal Status Of Women, Kimberly Kushner Jan 2023

Non-Alcoholic Fatty Liver Disease And Metabolic Syndrome: The Role Of Gender Differences And Menopausal Status Of Women, Kimberly Kushner

Walden Dissertations and Doctoral Studies

There are few studies that investigate the association between non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome (MetS) predominantly in menopausal women. This quantitative study investigated the association between MetS and NAFLD while controlling for age, gender, ethnicity, and menopausal status of women. The theoretical framework that helps establish and guide the research was the diffusion of innovation (DOI). A multivariable logistic regression was conducted using secondary data from the National Health and Nutrition Examination Survey. There is a statistically significant association between MetS, and NAFLD after controlling for age (OR = 2.96, 95% CI = 2.319–3.778, p < 0.001). However, ethnicity was not statistically significant. After further controlling for gender, the relationship remained statistically significant and exhibited a decrease in risk for females compared to males (OR = -.734, 95%CI = .387–.596, p < 0.001). Lastly, focusing on women only, and further controlling for menopausal status, the association between MetS and NAFLD was still statistically significant (OR = 2.227, p < 0.001). Mexican Americans, other Hispanics, and Non-Hispanic Black women were at higher risk (95% CI 1.102–7.039, 1.321–5.351, and 1.255–3.013, respectively). Implications for positive social change include adopting proactive and preventative strategies that can improve the quality of life for vulnerable patients and reduce morbidity and mortality associated with MetS and NAFLD.

Births to teenagers continue to be of concern in rural areas however, little is known about the association between inadequate PNC and poor infant outcomes in teenage populations. Previous studies have determined that greater risk of inadequate PNC has been linked to more rural areas compared to more urban areas. WV is the third most rural state …


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.

The Application Of Time Series Analysis To Injury Epidemiology Data, Eric Wayne Lundstrom

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Injury fatality rates in the United States (US) decreased throughout the majority of the 20th century, mostly due to declining rates of occupational and motor vehicle injuries. However, near the beginning of the 21st century, fatal injury rates in the US began to increase. This is principally due to the nation’s opioid epidemic, which has been characterized by different epidemic “waves”, each driven by overdoses associated with specific substances. Given the temporally dynamic nature of US injury trends, this study aimed to explore the application of time series analysis to injury data in the US. First, rates of non-fatal …

Driving After Marijuana Use Among Us College Students During The Covid-19 Pandemic, Yuni Tang Jan 2023

Driving After Marijuana Use Among Us College Students During The Covid-19 Pandemic, Yuni Tang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Adolescents and college-aged adults account for a large proportion of the United States population and are susceptible to drugs, including marijuana. Since the late 1960s in the United States, numerous states have legalized marijuana for medical and recreational purposes. These recent policy changes may alter people’s attitudes and behaviors about marijuana use, particularly young adults. The expansion of state-level marijuana legalization may also increase accessibility in younger populations and increase reckless driving behavior associated with marijuana use, including driving after marijuana use. During the COVID-19 pandemic, adolescents and young adults experienced heightened stress and anxiety, which have significantly contributed …

Bacteriuria In Older Adults Triggers Confusion In Healthcare Providers: A Mindful Pause To Treat The Worry, Eva M Amenta, Robin L P Jump, Barbara W Trautner Jan 2023

Bacteriuria In Older Adults Triggers Confusion In Healthcare Providers: A Mindful Pause To Treat The Worry, Eva M Amenta, Robin L P Jump, Barbara W Trautner

Faculty, Staff and Students Publications

The evidence base for refraining from screening for or treating asymptomatic bacteriuria (ASB) in older adults is strong, but both practices remain prevalent. Clinical confusion over how to respond to a change from baseline, when to order a urinalysis and urine culture, and what to do with a positive urine culture fuels unnecessary antibiotic use for ASB. If the provider can take a mindful pause to apply evidenced-based assessment tools, the resulting increased clarity in how to manage the situation can reduce overtreatment of ASB.

Journal Articles: Epidemiology

The chronic infection hypothesis for novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant emergence is increasingly gaining credence following the appearance of Omicron. Here, we investigate intrahost evolution and genetic diversity of lineage B.1.517 during a SARS-CoV-2 chronic infection lasting for 471 days (and still ongoing) with consistently recovered infectious virus and high viral genome copies. During the infection, we find an accelerated virus evolutionary rate translating to 35 nucleotide substitutions per year, approximately 2-fold higher than the global SARS-CoV-2 evolutionary rate. This intrahost evolution results in the emergence and persistence of at least three genetically distinct genotypes, suggesting …

Apoptosis alteration is responsible for tumorigenesis and tumor resistance to therapies. The natural product Tanshinone IIA (Tan IIA) exhibits potent inhibitory effects against various tumors. However, the effect of Tan IIA on apoptosis and its underlying mechanism remains elusive in oral squamous cell carcinoma (OSCC). Here, we demonstrated that Tan IIA dose-dependently suppressed cell viability and colony formation in CAL27, SCC4, and SCC25 cells. Moreover, Tan IIA inhibited Akt activation from inducing Foxo3a dephosphorylation and PUMA-mediated apoptosis. PUMA or Foxo3a knockdown compromised the inhibitory effect of Tan IIA on OSCC cells. Tan IIA administration inhibited CAL27-deprived xenograft tumor growth and …

Background:

To date, most countries worldwide have declared that the pandemic of COVID-19 is over, while the WHO has not officially ended the COVID-19 pandemic, and China still insists on the personalized dynamic COVID-free policy. Large-scale nucleic acid testing in Chinese communities and the manual interpretation for SARS-CoV-2 nucleic acid detection results pose a huge challenge for labour, quality and turnaround time (TAT) requirements. To solve this specific issue while increase the efficiency and accuracy of interpretation, we created an autoverification and guidance system (AGS) that can automatically interpret and report the COVID-19 reverse transcriptase-polymerase chain reaction (RT-PCR) results relaying …
