The Vipeholm Experiments: A Case Study Of Unethical Dental Research, Lainie Ross Md, Phd

Journal of the American College of Dentists

Modern-day research ethics training often begins with a discussion of the medical research atrocities committed by Nazi health care professionals and the resulting 10-principle Nuremberg Code, which is often considered to be the beginning of modern-day medical research regulations. It is occasionally mentioned that Nazi dentists also conducted unethical research in the concentration camps, and a few were brought to trial. In this manuscript, I compare two studies (one medical and one dental) conducted after World War II that violated the Nuremberg Code.

I describe and compare the well-known Willowbrook Hepatitis studies conducted by infectious disease doctors on vulnerable institutionalized …

Information Distortion As A Source Of Overconfidence In Managerial Decisions, Peter Boyle, Pete Nye

All Faculty Scholarship for the College of the Sciences

Managers confronting important strategic decisions often receive diagnostic information sequentially over time. As new information becomes available, they may need to update their understanding of the situation and possibly revise their preferences. During a decision, as a preference develops for one alternative course of action, a nonconscious goal of maintaining consistency between that preference, however tentative, and the new information can lead to an interpretation of that information so as to support the current preference. This tendency to bias or distort information to support the currently preferred option can in turn lead to even greater confidence in that leading option, …

The Mouth As A Mirror: A Parent- Hygienist’S Ethical Reflections On Oral Healthcare And Pompe Disease, Anika Atkins Ma, Rdh

Journal of the American College of Dentists

This reflective narrative explores the ethical tensions and emotional realities of a dental hygienist who is also the parent of a child with Pompe disease. Drawing from personal experience and care ethics philosophy, the author examines how traditional clinical frameworks—centered on autonomy, beneficence, and protocol— often fall short when addressing the needs of medically fragile children. The piece weaves in the work of care ethicists and pastoral ministry to embrace the philosophy of caregiving as presence, to suggest that oral healthcare must evolve to include responsiveness, context, and relationship-based decision-making. Through the dual lens of provider and parent, the narrative …

Restoring Trust: A Fair Chance At A Bright Smile And The Human Side Of School-Based Dentistry, Rubin Sorrell Ii, Mph, Dds

Journal of the American College of Dentists

The Fair Chance at a Bright Smile (FCAABS) program represents a humanistic, community- centered approach to dentistry that redefines access, education, and dignity in oral health. Developed and refined through a year-long pilot partnership with the San Francisco Unified School District, FCAABS integrates preventive dental care, oral health education, and career exposure for students from pre-kindergarten through high school. This manuscript argues that beyond clinical outcomes, FCAABS reveals a deeper truth: oral health is intrinsically social, emotional, and moral. It examines the program through the lens of the humanities and ethics, exploring how narrative, empathy, and cultural context inform both …

Hydroxypropyl Methylcellulose As A Mucoadhesive Polymer In Ethanol-Free Buprenorphine Gel For Neonatal Sublingual Delivery, Sanskruti Dave, Viren Soni, Samarth A. Shah, Walter K. Kraft, Gagan Kaushal

College of Pharmacy Faculty Papers

Buprenorphine (BUP) is widely used in the treatment of neonatal opioid withdrawal syndrome (NOWS). However, the most compounded formulation contains 30% ethanol, despite regulatory and clinical concerns regarding ethanol exposure in pediatric patients. Thus, this research aimed to develop an ethanol-free sublingual (SL) gel formulation of BUP that would be safe, stable, and suitable for NOWS. Multiple polymers were screened as gelling agents, with hydroxypropyl methylcellulose (HPMC) emerging as the ideal base polymer for the formulation due to its optimal pH, rheological characteristics, and stability. The formulated gels were stored at room temperature and refrigerated conditions for 30 days and …

Cationic Poly(Glucosamine)-Based Polymers Bind To Glycans With Varying Affinity Facilitating Transport Across The Glycocalyx Of Endothelial Cells, Claire Bridges, Lu Fu, Dan Wang, James D. Sterling, Susanna Liang, Shenda M. Baker, Jonathan Yeow, Megan S. Lord

Business and Information Technology Faculty Research & Creative Works

Natural polysaccharides, such as chitosan, offer promising avenues for drug delivery due to their cytocompatibility and ability to interact with cell surfaces. However, the endothelial glycocalyx, a glycan-rich extracellular matrix, presents a barrier that must be navigated for effective intracellular delivery. This study investigates how cationic poly(glucosamine)-based polymers, functionalized with guanidinium or ammonium groups, interact with key glycocalyx components including hyaluronan (HA) and heparan sulfate (HS). We demonstrate that these cationic polymers form tunable biomolecular condensates with glycans, with stronger binding observed for sulfated glycans, HS and heparin, than unsulfated HA. Derivatized chitosan polymers with varied cationic side chains exhibit …

Ex Vivo Microfluidic Model Identifies A Role For Shear Stress During Ovarian Tumor Cell Attachment To Peritoneal Mesothelial Cells, Vasilios A Morikis, Breanna Baker, Jillian A Martin, Angela Schab, Alessandra Dimauro, Gregory D Longmore, Whitney R Grither

2020-Current year OA Pubs

Ascites, or a pathologic accumulation of intra-abdominal fluid, is a key feature of intraperitoneally disseminating cancers, such as ovarian cancer. This pathological fluid buildup can influence the adhesive abilities of ovarian cancer cells, as they spread throughout the abdominal cavity to form metastatic implants on organs lined with a specialized monolayer of mesothelial cells. Robust methods for assessing the impact of fluid shear stress on this cell-cell interaction are lacking. Here, we develop and characterize a novel microfluidic device that allows for the determination of the attachment of ovarian tumor cells to mesothelial cells under the influence of fluid flow. …

For a long time, from the nineteenth century to most of the twentieth century, the cerebellum was thought to be an organ that regulates movement. Towards the end of the twentieth century, the brain functions associated with the cerebellum began to extend beyond motor control. Now, there is a consensus that the cerebellum is involved not only in motor functions but also in the most basic autonomic functions and the most complex cognitive and emotional functions, with a focus on predictions and internal models. A new functional model of the cerebellum is needed to explain all layers of brain functions …

Mechanisms responsible for skeletal muscle kidney crosstalk have not been defined. We have determined that a circulating mediator, signal regulatory protein α (SIRPα), impairs intracellular insulin-mediated functions. To elucidate the effect of myokine SIRPα on diabetic kidney disease (DKD), flox mice and muscle-specific (m-specific) SIRPα-KO mice were subjected to an obesity-induced model of diabetes, high-fat diet (HFD; 60%) or insulin-deficient hyperglycemia model, streptozotocin (STZ), and were subsequently exposed to anti-SIRPα monoclonal antibodies. In the obesity-induced diabetic mice, serum SIRPα increased. Genetic deletion of muscle SIRPα protected against obesity and improved intracellular insulin signaling in muscle and adipose tissue, with reduced …

Staff Education To Address Financial Barriers In Outpatient Psychiatric Care, Yvette Taffou Kamayou

Walden Dissertations and Doctoral Studies

This staff education project addressed financial barriers that prevent psychiatric outpatients from accessing consistent care. High no-show rates in outpatient psychiatry, often 20–40%, stem largely from costs such as co-pays, transportation, and medication, leading to missed appointments, poorer outcomes, and increased healthcare costs. The practice-focused question was “In an outpatient psychiatric clinic, does a targeted staff education program on non-judgmental financial discussions, sliding-scale fees, and telehealth options improve staff knowledge, confidence, and patient referral rates to resources over 8 weeks?” The purpose was to implement and evaluate a structured educational intervention to equip staff with tools for addressing financial barriers, …

HER2-low breast cancer (IHC 1+ or 2+ without HER2 gene amplification) is a distinct and understudied subtype. In a cohort of 14,593 early-stage breast cancer patients treated at MD Anderson from 2006 to 2019, 60.4% were HER2-low. Multivariable analysis showed HER2-low status was independently associated with race, histologic subtype, higher nuclear grade and stage, and estrogen receptor (ER) positivity. Among 2464 patients receiving neoadjuvant chemotherapy, HER2-low status was not linked to pathologic complete response (pCR), overall survival (OS), or disease-free survival (DFS) compared to HER2-0 tumors. Factors predicting pCR included nuclear grade III, stage I, invasive ductal carcinoma, lower ER/PR …

Proper regulation of ribosome biogenesis is essential for stem cell function and tissue homeostasis, yet its upstream control in adult intestinal stem cells (ISCs) remains unclear. Here, we identify the WD repeat protein Wdr4 as a key regulator of ISC homeostasis in the Drosophila midgut. Wdr4 cooperates with the methyltransferase Mettl1 to catalyze N⁷-methylguanosine (m⁷G) modification of let-7 miRNA. Wdr4 or Mettl1 depletion disrupts this modification, reducing let-7 levels and aberrantly activating TOR-JNK-dMyc signaling. This drives elevated ribosome biogenesis, ISC overproliferation, misdifferentiation, and intestinal dysplasia. Overexpression of let-7, inhibition of TOR, or suppression of JNK rescues these defects. Importantly, expression …
