A dual approach to addressing gaps in scholar diversity in aging research.

The number of people with Alzheimer's disease and related dementias (ADRD) in the United States is steadily increasing, with minoritized populations having a disproportionate burden of disease. One strategy to address the racial and ethnic disparities in aging is to diversify scholars in the field of aging, to increase dynamic solution development and create cultural congruence among researchers and participants. The National Institute on Aging has a committed effort to increase and diversify the number of scientists who conduct aging and ADRD research, placing a call for Centers to focus on this effort. In response to the National Institute on Aging call, the Carolina Center for Alzheimer's Disease and Minority Research, housed at the University of South Carolina, proposed a dual approach to addressing these gaps through a joint national conference and mentorship program for underrepresented minoritized faculty. After one year of the program, the participating scholars were surveyed, and successes and growth points of the program were identified to help guide the improvement of this dual approach to addressing gaps in scholar diversity in aging research.

Health disparities in mortality among individuals with HIV-associated dementia in South Carolina.

HIV disproportionately affects the South compared to other regions of the US. Some people living with HIV (PLWH) may acquire HIV-associated neurocognitive disorders (HAND), of which HIV-associated dementia (HAD) is the most severe form. This study aimed to examine the disparities in mortality among individuals with HAD. Data were obtained from the South Carolina Alzheimer's Disease and Related Dementias Registry from 2010 to 2016 (HAD: n = 505; N = 164,982). Logistic regression and Cox proportional hazards models were used to determine mortality related to HIV-associated dementia and potential sociodemographic differences. Adjusted models controlled for age, gender, race, rurality, and place of diagnosis. Individuals diagnosed in a nursing facility were three times more likely to die with HAD compared to those diagnosed in the community (OR: 3.25; 95% CI: 2.08-5.08). Black populations were more likely to die with HAD compared to White populations (OR: 1.52; 95% CI: 0.953-2.42). Disparities in mortality among patients with HAD were found in place of diagnosis and by race. Future research should determine if mortality among individuals with HAD were as a result of HAD or non-HIV related decline.

Sociodemographic Characteristics of HIV-Associated Dementia in the South Carolina Alzheimer's Disease Registry.

OBJECTIVES: Studies examining the sociodemographic characteristics associated with human immunodeficiency virus (HIV)-associated dementia (HAD) are lacking, especially in the southern United States. The aim of this study was to describe the characteristics of HAD using South Carolina Alzheimer's Disease Registry data, and examine these characteristics across two time periods. METHODS: Data were obtained from the population-based, South Carolina Alzheimer's Disease Registry from 2000-2006 and 2010-2016 (N = 165,487). Crude and multivariable logistic regression models were applied to determine sociodemographic characteristics associated with HAD by time period. RESULTS: Younger, Black, Other, men, and urban populations had greater odds of being diagnosed as having HAD in both time periods. For example, compared with individuals aged 85 years and older, individuals aged 18 to 34 had 97 times the odds (adjusted odds ratio 97.0; 95% confidence interval 31.6-297.8) of being diagnosed as having HAD. In 2010-2016, however, nursing facility populations had a greater odds of being diagnosed as having HAD. CONCLUSIONS: We found that younger populations (younger than 74 years), communities of color, men, urban populations, and nursing facility populations were more likely to have HAD. Future research should focus on the association between HAD and risk for Alzheimer's disease.

Highlighting the value of Alzheimer's disease-focused registries: lessons learned from cancer surveillance.

Like cancer, Alzheimer's disease and related dementias (ADRD) comprise a global health burden that can benefit tremendously from the power of disease registry data. With an aging population, the incidence, treatment, and mortality from ADRD is increasing and changing rapidly. In the same way that current cancer registries work toward prevention and control, so do ADRD registries. ADRD registries maintain a comprehensive and accurate registry of ADRD within their state, provide disease prevalence estimates to enable better planning for social and medical services, identify differences in disease prevalence among demographic groups, help those who care for individuals with ADRD, and foster research into risk factors for ADRD. ADRD registries offer a unique opportunity to conduct high-impact, scientifically rigorous research efficiently. As research on and development of ADRD treatments continue to be a priority, such registries can be powerful tools for conducting observational studies of the disease. This perspectives piece examines how established cancer registries can inform ADRD registries' impact on public health surveillance, research, and intervention, and inform and engage policymakers.

Sanitary sewage overflows, boil water advisories, and emergency room and urgent care visits for gastrointestinal illness: a case-crossover study in South Carolina, USA, 2013-2017.

BACKGROUND: Sanitary sewage overflows (SSOs) release raw sewage, which may contaminate the drinking water supply. Boil water advisories (BWAs) are issued during low or negative pressure events, alerting customers to potential contamination in the drinking water distribution system. OBJECTIVE: We evaluated the associations between SSOs and BWAs and diagnoses of gastrointestinal (GI) illness in Columbia, South Carolina, and neighboring communities, 2013-2017. METHODS: A symmetric bi-directional case-crossover study design was used to assess the role of SSOs and BWAs on Emergency Room and Urgent Care visits with a primary diagnosis of GI illness. Cases were considered exposed if an SSO or BWA occurred 0-4 days, 5-9 days, or 10-14 days prior to the diagnosis, within the same residential zip code. Effect modification was explored via stratification on participant-level factors (e.g., sex, race, age) and season (January-March versus April-December). RESULTS: There were 830 SSOs, 423 BWAs, and 25,969 cases of GI illness. Highest numbers of SSOs, BWAs and GI cases were observed in a zip code where >80% of residents identified as Black or African-American. SSOs were associated with a 13% increase in the odds of a diagnosis for GI illness during the 0-4 day hazard period, compared to control periods (Odds Ratio: 1.13, 95% Confidence Interval: 1.09, 1.18), while no associations were observed during the other hazard periods. BWAs were not associated with increased or decreased odds of GI illness during all three hazard periods. However, in stratified analyses BWAs issued between January-March were associated with higher odds of GI illness, compared to advisories issued between April-December, in all three hazard periods. SIGNIFICANCE: SSOs (all months) and BWAs (January-March) were associated with increased odds of a diagnosis of GI illness. Future research should examine sewage contamination of the drinking water distribution system, and mechanisms of sewage intrusion from SSOs. IMPACT: Sewage contains pathogens, which cause gastrointestinal (GI) illness. In Columbia, South Carolina, USA, between 2013-2017, there were 830 sanitary sewage overflows (SSOs). There were also 423 boil water advisories, which were issued during negative pressure events. Using case-crossover design, SSOs (all months) and boil water advisories (January-March) were associated with increased odds of Emergency Room and Urgent Care diagnoses of GI illness, potentially due to contamination of the drinking water distribution system. Lastly, we identified a community where >80% of residents identified as Black or African-American, which experienced a disproportionate burden of sewage exposure, compared to the rest of Columbia.

An exploratory study of indicators of recent nonmedical prescription stimulant use among college students.

Objective: To explore the relationship between past 30-day nonmedical prescription stimulant use (NPSU) and past 30-day marijuana and/or alcohol use, past 30-day risky marijuana and/or alcohol use, student demographics, and student activity involvement among college students. Participants: Sample of 604 college-aged students at two large universities in the southeastern U.S. Methods: A cross-sectional survey was completed electronically. Logistic regression was used to identify and test covariates of past 30-day NPSU. Results: Over 20% of participants self-reported past NPSU. Using both marijuana and alcohol in the past 30 days (B = 3.293, p = .002, OR= 26.91, 95% CI OR= 3.42, 211.92) and engaging in both risky marijuana and alcohol use (B = 2.095, p < .001, OR = 8.13, 95% CI OR = 2.52, 25.17) were significantly related to past 30-day NPSU. Conclusions: NPSU may be indicative of broader polysubstance use problems among college-aged students.

Examination of maternal near-miss experiences in the hospital setting among Black women in the United States.

INTRODUCTION: The high rate of maternal mortality among Black women in the United States continues to gain attention; yet research has not yet fully illuminated the precursors to these events, most impactful among them being "maternal near misses." A maternal near miss occurs when a woman nearly dies but survives a complication that occurred during pregnancy, childbirth, or within 42 days of termination of pregnancy. Researchers have focused on reviewing patient medical records after sentinel maternal events to help determine major contributors to them; however, qualitative studies with near-miss survivors, especially among Black women, may be a more useful approach. METHODS: Using a qualitative methodology, we conducted semi-structured interviews with 12 Black women to explore how they perceived the care provided to them during their near-miss experiences. Our study also employed a phenomenology framework to understand the lived experience of Black women who had a maternal near miss in the context of a hospital setting. RESULTS: We interviewed 12 women between October 2020 and March 2021. All participants had a maternal near miss between the years 2010 and 2020 and were aged between 19 and 41 years when they had their near-miss experience. These women identified communication, patient-provider relationship, skills/competency of staff, provider discrimination, systems issues, and emotional distress as major contributors to their experiences. CONCLUSION: Maternal near misses serve as a precursor to maternal mortality events. By listening to patients and their families recount their perspectives on what leads up to these near misses, we can unearth valuable lessons that can aid in the development of strategies and interventions to decrease the numbers of pregnancy-related deaths; especially among Black women who suffer disproportionately from maternal morbidity and mortality. Based on these findings, we recommend that hospitals and OB-GYN practices consider the unique predispositions of their Black patients; account for their own personal biases, revisit the near-miss experiences of past patients to keep patients central to care and build rapport between patients and hospital birthing support staff; and center discussions about improvements in care around racist structures and systems.

Reflections on Mentorship From Scientists and Mentors in an Alzheimer's Disease Focused Research Training Program.

This paper presents reflections on mentorship from scientists and mentors of the National Institute on Aging (NIA)-funded Carolina Center on Alzheimer's Disease and Minority Research (CCADMR). Using a network approach to mentoring, this program aims to increase the pipeline of underrepresented minority (URM) scientists studying Alzheimer's disease (AD) disparities. Six mentors and five scientists participated in interviews. Thematic analysis identified recurring themes; transcripts of mentors and scientists were compared. Most common thematic categories identified by mentors included experience interacting with scientists, goals as a mentor, recruitment of underrepresented minorities, scientists' challenges, and programmatic qualities. The most mentioned categories by scientists were challenges, seminars, working with mentors, career development, and project experience. The CCADMR will use findings to enhance the experience and training methods for future grant years. Results can benefit other training programs focused on aging and AD.

Genetic Risk Factors for Alzheimer's Disease in Racial/Ethnic Minority Populations in the U.S.: A Scoping Review.

Objectives: As the United States (U.S.) population rapidly ages, the incidence of Alzheimer's Disease and Related Dementias (ADRDs) is rising, with racial/ethnic minorities affected at disproportionate rates. Much research has been undertaken to test, sequence, and analyze genetic risk factors for ADRDs in Caucasian populations, but comparatively little has been done with racial/ethnic minority populations. We conducted a scoping review to examine the nature and extent of the research that has been published about the genetic factors of ADRDs among racial/ethnic minorities in the U.S. Design: Using an established scoping review methodological framework, we searched electronic databases for articles describing peer-reviewed empirical studies or Genome-Wide Association Studies that had been published 2005-2018 and focused on ADRD-related genes or genetic factors among underrepresented racial/ethnic minority population in the U.S. Results: Sixty-six articles met the inclusion criteria for full text review. Well-established ADRD genetic risk factors for Caucasian populations including APOE, APP, PSEN1, and PSEN2 have not been studied to the same degree in minority U.S. populations. Compared to the amount of research that has been conducted with Caucasian populations in the U.S., racial/ethnic minority communities are underrepresented. Conclusion: Given the projected growth of the aging population and incidence of ADRDs, particularly among racial/ethnic minorities, increased focus on this important segment of the population is warranted. Our review can aid researchers in developing fundamental research questions to determine the role that ADRD risk genes play in the heavier burden of ADRDs in racial/ethnic minority populations.

Mentorship and Training to Increase Diversity of Researchers and Practitioners in the Field of Aging and Alzheimer's Disease: A Scoping Review of Program Characteristics.

Objectives: Diversity is needed within the aging and Alzheimer's disease and related dementias (ADRD) research and practice workforce to comprehensively address health inequities faced by underrepresented minority (URM) older adults. We conducted a scoping review of training programs designed to diversify the pool of researchers and practitioners in the field of aging and ADRD. Methods: Online database searches yielded 3976 articles published from 1999 to 2019. Fourteen studies met the inclusion criteria. Results: All programs were from the United States and included URM populations. Nine programs included students, one targeted university faculty, and four targeted clinical staff. Only five programs were guided by theory. Discussion: Our review identified URMs' desire for culturally diverse and representative mentorship, the need for career development support at various training stages, and the importance of incorporating theory to program design. It also identified key characteristics for future program development, creation of systematic evaluation standards, and opportunities for promotion.

Ethical Challenges and Lessons Learned from Qualitative Research with Low-Income African American Women Living with HIV in the South.

African American women living with HIV (WLWH) in the U.S. South encounter heightened marginalization due to the complex intersections of race, gender, poverty, and HIV status. Social vulnerabilities experienced by individuals and communities in daily life have the potential to sharpen ethical tensions in the context of research. Thus, conducting ethical research requires attention to the contextual challenges and concerns of diverse research populations to tailor participant protections to a particular sociocultural context. Using principles from the Belmont Report, the present report draws on data from a qualitative study with 42 African American WLWH in the South by highlighting the first author's accounts of ethical challenges that emerged during data collection. Findings suggest that engaging participants in their natural environments can inform the development of ethical research strategies germane to women's lived experiences. Study findings also contribute to empirical guidance for investigators engaging marginalized populations in scientific research.

Temporal Trends in Cardiovascular Hospital Discharges Following a Mass Chlorine Exposure Event in Graniteville, South Carolina.

Background: On January 6, 2005, a train derailed in Graniteville, South Carolina, releasing nearly 60,000 kg of toxic chlorine gas. The disaster left nine people dead and was responsible for hundreds of hospitalizations and outpatient visits in the subsequent weeks. While chlorine gas primarily affects the respiratory tract, a growing body of evidence suggests that acute exposure may also cause vascular injury and cardiac toxicity. Here, we describe the incidence of cardiovascular hospitalizations among residents of the zip codes most affected by the chlorine gas plume, and compare the incidence of cardiovascular discharges in the years leading up to the event (2000-2004) to the incidence in the years following the event (2005-2014). Methods: De-identified hospital discharge information was collected from the South Carolina Revenue and Fiscal Affairs Office for individuals residing in the selected zip codes for the years 2000 to 2014. A quasi-experimental study design was utilized with a population-level interrupted time series model to examine hospital discharge rates for Graniteville-area residents for three cardiovascular diagnoses: hypertension (HTN), acute myocardial infarction (AMI), and coronary heart disease (CHD). We used linear regression with autoregressive error correction to compare slopes for pre- and post-spill time periods. Data from the 2000 and 2010 censuses were used to calculate rates and to provide information on potential demographic shifts over the course of the study. Results: A significant increase in hypertension-related hospital discharge rates was observed for the years following the Graniteville chlorine spill (slope 8.2, p < 0.001). Concurrent changes to CHD and AMI hospital discharge rates were in the opposite direction (slopes -3.2 and -0.3, p < 0.01 and 0.14, respectively). Importantly, the observed trend cannot be attributed to an aging population. Conclusions: An unusual increase in hypertension-related hospital discharge rates in the area affected by the Graniteville chlorine spill contrasts with national and state-level trends. A number of factors related to the spill may be contributing the observation: disaster-induced hypertension, healthcare services access issues, and, possibly, chlorine-induced susceptibility to vascular pathologies. Due to the limitations of our data, we cannot determine whether the individuals who visited the hospital were the ones exposed to chlorine gas, however, the finding warrants additional research. Future studies are needed to determine the etiology of the increase and whether individuals exposed to chlorine are at a heightened risk for hypertensive heart disease.

Sexual Behaviors, Mobile Technology Use, and Sexting Among College Students in the American South.

PURPOSE: To examine sexual, mobile technology, and sexting behaviors of college students. DESIGN: A cross-sectional study design was employed. SETTING: Study sites were 2 universities in the southern United States. SUBJECTS: Data were collected from 254 participants via online survey of college students. MEASURES: The survey included 268 items inclusive of measures from previously validated sources. Variables for this study included technology ownership/use, online/mobile dating site use, sexting behaviors/attitudes, and sexual behaviors. In particular, the Sexting Attitudes Scale has been previously validated with other researchers providing comparative data. ANALYSIS: Chi-square and Mann-Whitney tests were used for group comparisons. Logistic regression analysis was used to examine predictors of sexting behavior. RESULTS: Of the 254 participants, over 80% had ever had sex, and participants were more likely to use condoms with partners who they were not in a committed relationship compared to those to whom they were committed (χ2 = 27.324, P = .0001). Seventy percent had ever sexted, and sexting attitudes ranged from approximately 80% agreeing that sexting is "risky" or can leave one "vulnerable" compared to 43% agreeing that sexting is "fun." Sexting was associated with having multiple sexual partners (odds ratio [OR] = 2.47, 95% confidence interval [CI]: 1.36-4.47) and sexually transmitted infection testing history (OR = 2.08, 95% CI: 1.03-4.18). CONCLUSION: Study findings should be considered as interventionists plan sexual health and risk prevention programs for college students.
