Conceptualizing Caremark, Roy Shapira
Indiana Law Journal
Who is accountable for corporate compliance failures? The issue of compliance has emerged as one of the most significant developments in corporate governance over the past decades. However, until recently, corporate law has had surprisingly little to say about the question, leaving the policing of issues such as toxic pollution, product safety, or data privacy, to other regulators. This situation has changed dramatically over the past few years. Today, virtually every corporate fiasco is followed by an oversight duty lawsuit against the company’s directors and officers for not doing enough to prevent the debacle. But the rapid resurgence of oversight …
Federalism, State Action, And Workers' Medical Privacy, Ani B. Satz
Federalism, State Action, And Workers' Medical Privacy, Ani B. Satz
Indiana Law Journal
Injured workers entering state workers’ compensation systems effectively forego their medical privacy. This is due to widespread judicial misinterpretation of the HIPAA Privacy Rule (HPR) as excluding injured workers from federal medical privacy protections. As a result, medical privacy for workers’ compensation claims is effectively governed by state law. This Article argues that states have failed to protect the medical privacy of injured workers adequately and that there is a pressing need for legislative reform. The Article presents the first comprehensive survey in the legal literature of state action protecting the medical privacy of injured workers. Part I describes the …
Enhancing Patient-Centered Care Through Predictive Modeling To Optimize Appointment Scheduling In Pediatric Care, Linda Anna Penitusi-Burford
Enhancing Patient-Centered Care Through Predictive Modeling To Optimize Appointment Scheduling In Pediatric Care, Linda Anna Penitusi-Burford
Doctor of Business Administration (DBA)
This study evaluated the predictive performance of three forecasting models—Autoregressive Integrated Moving Average (ARIMA), Prophet, and Long Short-Term Memory (LSTM)—to determine which most accurately forecasts pediatric appointment availability. The research was guided by the theory that accurate forecasting can enhance healthcare scheduling by aligning appointment supply with patient demand, thereby advancing patient-centered care (PCC).
A quantitative, comparative design was employed using two years of pediatric online scheduling records. The methodological framework incorporated multiple forecast horizons (30–180 days) and statistical analyses, including ANOVA, paired sample t-tests, and regression. Model performance was assessed using standard error metrics: Mean Absolute Error (MAE), Mean …

Dean's Leadership Council Library Research Prize
All biological functions in living organisms depend on the activity of proteins, long molecules that must twist and fold into specific shapes to become functional. A subset of proteins known as molecular chaperones is essential for maintaining cellular health by assisting other proteins in folding correctly and refolding those damaged by stress. When proteins misfold and clump together, they can form toxic aggregates linked to many neurodegenerative diseases, including Alzheimer’s disease (AD), one of the leading causes of death in the United States. In AD, these protein aggregates form organized, elongated structures referred to as amyloid-like fibrils, which damage neurons …

Background: Education is strongly associated with cognitive outcomes at older ages, yet the extent to which these associations reflect causal effects remains uncertain due to potential confounding. Methods: Leveraging changes in historical measures of state-level education policies as natural experiments, we estimated the effects of educational attainment on cognitive performance over 10 years in 20,248 non-Hispanic Black and non-Hispanic White participants, aged 45+ in the Reasons for Geographic and Racial Disparities in Stroke cohort (2003-2020) by (1) using state- and year-specific compulsory schooling laws, school-term length, attendance rate, and student-teacher ratio policies to predict educational attainment for US Census microsample …
Educators’ Perceptions Of The Components That Influence Student Behavior And The Impact Restorative Practices And Community Circles Have On Improving Overall Well-Being In Students, Catherine Dulovic
Selected Full Text Dissertations, 2011-
Restorative Practices have been utilized in many schools as an alternative to traditional disciplinary methods. Traditional methods such as Out of School Suspension (OSS) and In-School Suspension (ISS) can lead to feelings of isolation and impact students’ attitudes towards school and community. Community Circles are often used in conjunction with Restorative Practices to support the development of the whole child, build relationships, promote positive discipline, and create a trauma sensitive environment that includes mindfulness practices. The current research examined educators’ perspective of the components that influence student behavior and the impact Restorative Practices and Community Circles have on improving behavior …

Information Technology (IT) use gives rise to a wide variety of outcomes. This stems in part from the divergent ways in which individuals understand technology. While the sensemaking literature unveils how meaning is attached to organizational phenomena via cognitive and social processes, it overlooks the discovery dimension of making sense, that is detecting the role of the IT artifact in bringing about outcomes. In other words, there is a need to explain how the IT artifact contributes to technology sensemaking and its outcomes. This paper presents a framework that enables scholars to analyze the IT artifact’s role in technology sensemaking …

The Moderating Role Of Hospital Staffing Levels On The Effectiveness Of Clinical Decision Support Systems In Mitigating Patient Readmission Rates, Youyou Tao, Arindam Brahma, Kevin Baldwin, Rui Sundrup, Dezhi Wu
Information Systems and Business Analytics Faculty Works
Healthcare staffing shortages and high 30-day readmission rates are pressing challenges in today's healthcare systems. While extensive studies have explored the positive impact of Health Information Technology (HIT) on health outcomes, the effect of hospital staffing on HIT effectiveness, particularly Clinical Decision Support Systems (CDSS), is underexplored. Therefore, we examine whether physician and resident staffing levels moderate the impact of CDSS on 30-day readmission rates. After analyzing data from 1,605 hospitals in the United States from 2017 and 2018, we found that the effect of CDSS implementation in reducing 30-day readmission rates is more pronounced in hospitals with lower bed-to-physician …
A Preliminary Program Evaluation: Rates Of Intimate Partner Violence In An Urban Child Welfare Prevention Program, Athena Roca
A Preliminary Program Evaluation: Rates Of Intimate Partner Violence In An Urban Child Welfare Prevention Program, Athena Roca
PCOM Psychology Dissertations
Intimate partner violence (IPV) remains a pervasive public health concern with significant consequences for families. Traditional batterer intervention programs (BIPs), which often focus solely on the person causing harm (PCH), have demonstrated limited success in reducing recidivism, particularly when grounded in punitive or authoritarian models. This study evaluated the Child-Welfare IPV Prevention Program (CWIPVPP), a family-centered, trauma-informed intervention that engages the PCH, co-parents, and children to reduce IPV-related behaviors and promote healthier family functioning.
Recidivism indicators, including domestic violence incident reports (DIRs) and arrests, were analyzed for 57 fathers referred to the program, with 53 retained for final analyses. A …

Ewing sarcoma (ES) is a high-grade bone and soft tissue tumor in adolescents and young adults. Cytotoxic chemotherapy does not improve prognosis, especially for advanced ES patients who have a 5-year survival of 30% or less [1, 2]. Molecular targeted therapy emerges as a promising strategy to battle ES, given its unique driver mutations resulting from the fusion of the EWS and one of the ETS genes, but the feasibility of directly blocking EWS-ETS function has not yet been established [3]. To search for new therapeutic targets, we began with an analysis of the Cancer Dependency Map (DepMap) datasets that …

Background: In recent years, the United States (U.S.) healthcare system has faced financial challenges resulting from changing reimbursement models, fluctuations in sources of investment, and a global pandemic. These factors have resulted in an influx of bankruptcy filings among healthcare organizations. This study explores the number of healthcare organizations filing for bankruptcy as means to reorganize (Chapter 11) or liquidate assets (Chapter 7), and examines whether organizational size, defined by assets and liabilities, influences the success of reorganization. The research on bankruptcy among healthcare organizations has been limited to larger businesses including hospitals and nursing homes. This study investigates all …

Pre-exposure prophylaxis (PrEP) has emerged as a prominent approach for the prevention of HIV infections. While the latest advances have resulted in effective oral and injectable product options, there are still gaps in on-demand, event-driven, topical products for HIV prevention that are safe and effective. Here we describe the formulation development of a dual-compartment topical insert containing tenofovir alafenamide fumarate (TAF) and elvitegravir (EVG) that may be administered when needed, vaginally or rectally, pre- or post-coitus, for flexible HIV prophylaxis. Specifically, we describe the lab-scale formulation development, preclinical mucosal safety and pharmacokinetics (PK) testing in rabbits, long-term stability, and scale-up …

Highly effective antiretroviral-based HIV prevention plays an important role in ending the global HIV/AIDS epidemic. However, the sustainable control of the epidemic is hampered by unequal access to prevention options, including HIV testing, alongside with drug resistance and ongoing barriers to accessing sustainable HIV treatment. Therefore, an HIV vaccine, combined with effective prevention and treatment, remains an absolute necessity to control the epidemic. Yet, the recent discontinuation of four major vaccine efficacy studies is raising concerns about the future of HIV vaccine research and development globally, and particularly in the European region where funding for vaccine research and development has …

Gut inflammatory diseases cause microbial dysbiosis. Human immunodeficiency virus-1 (HIV) infection disrupts intestinal integrity, subverts repair/renewal pathways, impairs mucosal immunity and propels microbial dysbiosis. However, microbial metabolic mechanisms driving repair mechanisms in virally inflamed gut are not well understood. We investigated the capability and mechanisms of gut microbes to restore epithelial barriers and mucosal immunity in virally inflamed gut by using a multipronged approach: an in vivo simian immunodeficiency virus (SIV)-infected nonhuman primate model of HIV/AIDS, ex vivo HIV-exposed human colorectal explants and primary human intestinal epithelial cells. SIV infection reprogrammed tryptophan (TRP) metabolism, increasing kynurenine catabolite levels that are …

Exposure to endocrine-disrupting chemicals such as phthalates may increase risk of hypertensive disorders of pregnancy (HDP). Prior studies lack investigation of chemical mixtures, phthalate replacements, or key periods of susceptibility including early pregnancy. In the present study, we used a longitudinal approach to evaluate gestational exposure to phthalates and replacements, as both single-pollutants and mixtures, in association with blood pressure and diagnosis of preeclampsia or any HDP. The Human Placenta and Phthalates prospective pregnancy cohort includes 291 participants recruited from two U.S. clinics. Urinary metabolites of ten phthalates and replacements were quantified at up to 8 time points per individual …

METHODS:
This was a cross-sectional analysis of county-level data in the United States from January 2018 to December 2021. Using the level of maternity care access, we categorized counties into desert, low access, moderate access, and full access. The primary outcome of interest was maternal mortality rate per 100,000 live births. A secondary outcome was pregnancy-related mortality rate per 100,000 live births. Absolute risk differences and adjusted incidence rate ratios were calculated for maternal mortality and pregnancy-related mortality with multivariable negative binomial mixed-effects …

[Introduction] We read with interest the recent study by Rosenfeld et al.¹ However, we have several clinical and methodological concerns about this study.¹
First, this study's propensity score matching (PSM) lacked key clinical confounders, including perinatal risk factors and the highest systolic/diastolic blood pressures. Smoking, alcohol use, and multifetal gestation, which influence blood pressure during pregnancy,²,³ potentially affect both primary and secondary outcomes. Additionally, the authors did not report standardized mean differences before and after PSM, which are essential for assessing balance.⁴

Background
Cardiovascular diseases are the leading cause of mortality in the United States, presenting significant public health challenges and financial burdens, particularly in Southeastern Virginia, where African American and Hispanic (AA&H) populations are disproportionately affected.
Methods
This retrospective observational study analyzed data from 30,855 hospital discharges of AA&H patients across Southeastern Virginia from 2016 to 2020, focusing on individuals aged 18 to 85 with cardiovascular diseases. Utilizing the Virginia Health Information database, we examined demographic information, clinical data, and healthcare utilization patterns through hypothesis tests and regression models to explore associations between these variables and the economic impacts of cardiovascular …

Objective
Although some studies show that exercise decreases the incidence of gestational diabetes mellitus (GDM), the optimal exercise intensity during pregnancy remains unclear. We examined GDM risk according to exercise intensity in pregnant individuals.
Methods
We analyzed data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers‐to‐Be (nuMoM2b), a prospective study enrolling nulliparous individuals in the first trimester. Participants with pregestational diabetes or delivery before 20 weeks were excluded. Exercise intensity during the first (6–13 weeks’ gestation) and early second (16–21 weeks’ gestation) trimesters was categorized by metabolic equivalent of task hours per week (MET‐hr/week) as none, low intensity (< 7.5), moderate intensity (7.5–14.9), or high intensity (≥ 15). The primary outcome was GDM; secondary outcomes included preeclampsia, gestational hypertension, preterm birth, small‐for‐gestational‐age birth, and stillbirth. Adjusted relative risks (aRRs) with 95% confidence intervals (CIs) were calculated using a generalized linear mixed‐effects model with a Poisson distribution and robust error variance, controlling for the random effects of individuals and potential confounders.

Objective
To use superb microvascular imaging (SMI) to longitudinally evaluate blood flow in intravillous arterioles (IVA) in pregnancy, and to develop reference ranges for IVA pulsatility index (PI) and peak systolic velocity (PSV) from 12 to 38 weeks' gestation.
Methods
The data for this study were obtained from the National Institutes of Health-funded Human Placenta Project. Eligible for inclusion were women aged 18-35 years, with a body mass index of < 30 kg/m², without comorbidities, with a singleton pregnancy conceived spontaneously and a gestational age of ≤ 13 + 6 weeks. Exclusion criteria were maternal or neonatal complications, fetal or umbilical cord anomalies, abnormal placental implantation and delivery < 37 weeks. Each participant underwent eight ultrasound examinations during pregnancy. Using SMI technology, the total number of IVA identified was recorded in a sagittal placental section at the level of cord insertion. The PI and PSV were measured in a total of six IVA (two in the central portion of the placenta, two peripherally towards the uterine fundal portion and two peripherally towards the lower uterine segment). Umbilical artery (UA)-PI was also obtained. Multilevel regression models were used to create reference ranges for IVA-PI and IVA-PSV at 12-38 weeks' gestation.
Results
A total of 90 women fulfilled the study criteria. IVA-PI decreased throughout pregnancy from a mean ± SD of 1.04 ± 0.23 in the first trimester (at 12-13 weeks) …

Background:
In 2022, 3100 adolescent girls and young women in sub-Saharan Africa experienced new HIV infections each week. HIV pre-exposure prophylaxis (PrEP) is effective at preventing HIV but has limited uptake and persistence. Mobile health (mHealth) interventions can improve medication adherence; however, their utility to improve PrEP adherence among adolescent girls and young women is not well established.
Objective:
This scoping review synthesizes evidence supporting mHealth for PrEP among adolescent girls and young women in sub-Saharan Africa and identifies strategies for further evaluation.
Methods:
We searched PubMed and Google Scholar databases, expert referrals, and reference lists using the following eligibility …
