Masculine Ideals And Health In Older Men: Findings From The Wisconsin Longitudinal Study, Shane D. Burns, Patricia Drentea Dec 2023

Masculine Ideals And Health In Older Men: Findings From The Wisconsin Longitudinal Study, Shane D. Burns, Patricia Drentea

APC Fund

How do older men’s masculine ideals affect their health? Are masculine activities involved in this relationship? Masculine identity upholds beliefs about masculine enactment. These beliefs can be detrimental to men and can lead to behaviors that can put undue stress on them. We examine how masculine ideals are associated with health and depressive symptomatology in older men. We used 2011 data from the Wisconsin Longitudinal Study (n = 2,594) to investigate how masculine ideals inform older men’s health and how participation in masculine activities might shape these outcomes. Findings from this study illustrate that traditional masculine ideals are associated …

Introduction: A cognitive theory of culture as socially distributed cultural models has proven useful in research. Cultural models exist in two forms: the model shared by individuals in a social group, and individual versions of that model modified by personal experience. In previous research we documented a shared cultural model of substance use risk among a general population sample in urban Brazil. Here we examine how this model is distributed among persons under treatment for substance use/misuse and the implications for perceived and self-stigma.

Methods: A convenience sample of 133 persons under treatment rated the influence of risk factors for …

APC Fund

Over 50,000 people die annually from opioid overdoses in the United States leading to what has become known as the “opioid epidemic.” This is of heightened concern in states like Alabama that experience higher rates of overall drug use and overdose deaths. Thus, it is increasingly important for college students in Alabama to learn about how the opioid epidemic is affecting their communities. Previous studies have demonstrated that engaging non-majors in innovative active-learning oriented pedagogies like service-learning can enhance their understanding and awareness about contemporary societal issues. Despite its pedagogical potential, the impact of opioid-related service-learning, particularly for non-majors, continues …

Associations of HLA class II alleles with genital chlamydial infection outcomes have been reported, especially HLA DQB1*06. However, the potential role of DQB1*06 in influencing reinfection risk has still not been established. The purpose of this study was to determine whether the association of DQB1*06 with chlamydia reinfection was impacted by any other nearby HLA class II variants that were also associated with reinfection. We used next-generation sequencing to map HLA class II variants spanning the HLA-DQ and -DR loci. DQB1*06 as well as DQB1*04 were confirmed as significant predictors of chlamydia reinfection, when controlling for age and percent African …

APC Fund

Human Cytomegalovirus (HCMV) is a ubiquitous member of the Herpesviridae family, responsible for the most common congenital viral infection—congenital Cytomegalovirus (cCMV) infection. While a majority of HCMV infections in children and adults are asymptomatic, HCMV is well known to cause severe infections in the immunocompromised individual and maternal infections with variable long-term sequelae after maternal–fetal transmission with primary or nonprimary infections. HCMV seroprevalence and cCMV incidence vary by geographic area and demographic characteristics like race and socioeconomic status. While cCMV birth prevalence ranges from 0.2% to 6% in different parts of the world, it is influenced by regional HCMV seroprevalence …

APC Fund

Streptococcus pneumoniae (Spn) resides in the nasopharynx where it can disseminate to cause disease. One key Spn virulence factor is pneumococcal surface protein A (PspA), which promotes survival by blocking the antimicrobial peptide lactoferricin. PspA has also been shown to mediate attachment to dying epithelial cells in the lower airway due to its binding of cell surface-bound mammalian (m)GAPDH. Importantly, the role of PspA during colonization is not well understood. Wildtype Spn was present in nasal lavage elutes collected from asymptomatically colonized mice at levels ∼10-fold higher that its isogenic PspA-deficient mutant (ΔpspA). Wildtype Spn also …

There are diverse types of health care systems, policies and health care organizations existing in health care delivery arrangements across the world (1). Two distinct influential groups of professionals have emerged as a result. They are: 1. Macro-level, population-oriented heath policy planners and analysts (health policy professionals–HPP) and 2. More micro-level, institutionally-oriented managers and organizational leaders and executives (health management professionals–HMP). As the old idiom goes, “one can't see the forest for the trees.” Are HPP professionals at such “altitude” that they have a clear vision of the forest, but fail to understand how things are on the …

APC Fund

The central circadian regulator within the suprachiasmatic nucleus transmits time of day information by a diurnal spiking rhythm driven by molecular clock genes controlling membrane excitability. Most brain regions, including the hippocampus, harbor similar intrinsic circadian transcriptional machinery, but whether these molecular programs generate oscillations of membrane properties is unclear. Here, we show that intrinsic excitability of mouse dentate granule neurons exhibits a 24-h oscillation that controls spiking probability. Diurnal changes in excitability are mediated by antiphase G-protein regulation of potassium and sodium currents that reduce excitability during the Light phase. Disruption of the circadian transcriptional machinery by conditional …


Effectiveness Of The Invisalign System For Deep Bite Correction, Jerry D. Spillers Iii Jan 2023

Effectiveness Of The Invisalign System For Deep Bite Correction, Jerry D. Spillers Iii

All ETDs from UAB

Objective: To assess the dental and skeletal changes resulting from correction of a deep bite using Invisalign (Align Technology, Santa Clara, CA, USA).Methods: This is a retrospective case series study which analyzed pre and post treatment cephalograms for 37 adult deep bite patients. Each patient was treated by one, experi-enced clinician using the same treatment protocols. Nineteen variables, ten linear and nine angular. The Wilcoxon analysis was used to determine if there was a significant dif-ference in pre and post treatment variables. Results: Statistically significant differences (P<0.05) occurred for 14 of 19 variables. These include a decrease in Overjet (-0.97 mm), decrease in overbite (-4.07 mm), extru-sion of the upper first molar (0.47 mm), intrusion of the upper incisor (-0.67mm), extru-sion of the lower second molar (1.01 mm), lower first molar (1.20 mm), lower second premolar (1.70 mm), and lower first premolar (1.74 mm), intrusion of the lower incisor (-1.88 mm), proclination of lower incisor, (4.09 ̊), and increase in SN-MP (0.54 mm). A decrease in anterior occlusal plane (AOP) was also statistically significant. Conclusions: Invisalign is an effective treatment modality for correcting dental deep bites through posterior extrusion and anterior intrusion. Minimal skeletal changes are seen when correcting deep bites with Invisalign.

In regards to identifying safe drug candidates, pharmacovigilance studies of adverse event case reports identified that women are more likely to experience an adverse event, and …


Social Determinants Of Health And Blood Pressure Control In Black And White Us Adults, Oluwasegun Philip Akinyelure Jan 2023

Social Determinants Of Health And Blood Pressure Control In Black And White Us Adults, Oluwasegun Philip Akinyelure

All ETDs from UAB

Black adults in the US have 2 to 3 times higher rates of cardiovascular disease (CVD) mortality compared to White adults. Most of the excess CVD mortality in Black adults has been attributed to their higher prevalence of hypertension and uncontrolled blood pressure (BP). In October 2020, the US Surgeon General published a Call-to-Action to improve hypertension control and identified social determinants of health (SDOH) as a major contributor to Black:White disparities in hypertension control. Prior research has showed that SDOH are associated with excess hypertension risk among Black compared with White adults, but data on their association with BP …

Pharmacologic Proteasome Activators Ameliorate Alzheimer's-Like Pathology In Ad Fly Models, Mehar Bano

All ETDs from UAB

The proteasome is a large multi-subunit protease responsible for the degradation and removal of oxidized, misfolded, and polyubiquitinated proteins. The proteasome plays a critical role in nervous system processes. This includes the maintenance of cellular homeostasis in neurons (1). It also includes synaptic efficacy and plasticity as well as protein turnover, presynaptic vesicle transport, and neuronal protesostasis. Proteasome function is impaired as a consequence of aging, which is aggravated by conditions like Alzheimer's Disease and Related-Dementias (AD, ADRD) (2). According to earlier work from our lab the proteasome is critical to how quickly AD progresses. In Drosophila, human cells, and …


Acute Placental Inflammation And Growth Outcomes In Preterm Infants, Emily Gunawan Jan 2023

Acute Placental Inflammation And Growth Outcomes In Preterm Infants, Emily Gunawan

All ETDs from UAB

Background. Acute placental inflammation (API) has been associated with various adverse outcomes in preterm infants. However, little is known about how API affects their body composition and growth outcomes. This study aims to examine the association between API and growth outcomes in preterm infants. Methods. We conducted a retrospective cohort study of mother-infant dyads born < 326/7 weeks of gestation with fat mass (FM) accretion measured using air displacement plethysmography at term-equivalent age. API severity including maternal inflammatory response (MIR) and fetal inflammatory response (FIR) was staged according to criteria by Society for Pediatric Pathology based on placental pathology reports. We examined the differences in characteristics of mother-infant dyads by API severity using ANOVA or the Kruskall-Wallis test. The association between API severity and growth outcomes was analyzed using linear regression models and adjusted for statistically significant confounders. Mediation analyses were used to study the direct and indirect association of API and growth outcomes via gestational age. Results. Among 375 mother-infant dyads analyzed, 104 (28%) dyads had MIR. FIR was found in 82% of dyads with MIR. Adjusted models indicated that API severity progression was positively associated with FM accretion. Gestational age partially (49%) iv mediated the association between API severity and FM z score (indirect effect: b=0.12, 95% CI: 0.05-0.19; direct effect: b=0.12, 95% CI: 0.01-0.25). Conclusions. API severity is associated with growth outcomes and helps to accurately predict body composition in preterm infants.

Understanding Molecular Mechanisms Of Glioblastoama Resistance To Design Novel Combinatorial Therapies, Amber B. Jones Jan 2023

Understanding Molecular Mechanisms Of Glioblastoama Resistance To Design Novel Combinatorial Therapies, Amber B. Jones

All ETDs from UAB

Treatment options for the universally lethal brain tumor, glioblastoma (GBM), are severely limited and often unsuccessful in fully eradicating the disease. Extremely aggressive in nature, GBM cells often implore suppressive mechanisms to evade therapeutic detection which aids in the dismal 15-month median survival rate. Facilitating disease severity and more importantly, disease recurrence, are the immunosuppressive and chemoresistant phenotypes of GBM cells. Specifically, the DNA alkylating agent, temozolomide (TMZ) possesses lymphodepleting properties shunting robust immune cell infiltration into an immunologically cold tumor microenvironment. Additionally, through inherent or acquired mechanisms, GBM tumors commonly become resistant to the DNA damaging effects of TMZ …
