Efficacy Of Psychotherapy-Supported Mdma In The Treatment Of Complex Posttraumatic Stress Disorder, Danielle Dubois

Yale School of Medicine Physician Associate Program Theses

Complex Posttraumatic Stress Disorder is a debilitating psychiatric disorder with no approved treatment options despite the high symptom burden and diminished quality of life. Randomized controlled trials have shown robust attenuation of posttraumatic stress disorder symptomatology using treatment with 3,4-Methylenedioxymethamphetamine (MDMA) plus psychotherapy, but individuals with complex traumatization have not been studied explicitly. Prior trials primarily utilized an inactive placebo group, undermining the interpretation of the results due to concern for unblinding of subjects. The proposed study is the first to utilize an active comparator to test a key hypothesis related to MDMA’s mechanism of action and to preserve blinding. …

Comparison Of Oral Carotene Supplementation And Oral Polypodium Leucotomas In Preventing Photodamage, Jazmin Martinez

Yale School of Medicine Physician Associate Program Theses

Skin exposure to ultraviolet (UV) irradiance is the major cause of skin disorders, such as sunburn and nonmelanoma cancer. The current standard of care for photoprotection is the daily use of sunscreen, although patient adherence and adequate application continues to be an issue. Current data show systemic photoprotection can be added to sunscreen use to reduce the risk of cutaneous diseases. This randomized controlled study will investigate whether supplementation with Polypodium leucotomas versus carotenoid supplementation versus the standard of care, provide increased photoprotection in adults with Fitzpatrick skin types II-IV. Outcomes will be measured by comparing the minimal erythema dose …

Periodontal Regeneration Risk Assessment In The Treatment Of Intrabony Defects., Robert A. Levine, Muhammad H A Saleh, Debora R. Dias, Jeffrey Ganeles, Maurício G. Araújo, Franck Renouard, Harold M. Pinsky, Preston D. Miller, Hom-Lay Wang

HPD Articles

BACKGROUND: Regenerative approaches performed in periodontics seems to be efficient in treating intrabony defects. There are, however, many factors that may affect the predictability of the regenerative procedures. The present article aimed to propose a new risk assessment tool for treating periodontal intrabony defects by regenerative therapy.

METHODS: Different variables that could affect the success of a regenerative procedure were considered based on their impact on (i) the wound healing potential, promoting wound stability, cells, and angiogenesis, or (ii) the ability to clean the root surface and maintain an optimal plaque control or (iii) aesthetics (risk for gingival recession).

RESULTS: …

Treatment Decisions And The Use Of Mek Inhibitors For Children With Neurofibromatosis Type 1-Related Plexiform Neurofibromas, Amy E Armstrong, Allan J Belzberg, John R Crawford, Angela C Hirbe, Zhihong J Wang

2020-Current year OA Pubs

Neurofibromatosis type 1 (NF1), the most common tumor predisposition syndrome, occurs when NF1 gene variants result in loss of neurofibromin, a negative regulator of RAS activity. Plexiform neurofibromas (PN) are peripheral nerve sheath tumors that develop in patients with NF1 and are associated with substantial morbidity and for which, until recently, the only treatment was surgical resection. However, surgery carries several risks and a proportion of PN are considered inoperable. Understanding the genetic underpinnings of PN led to the investigation of targeted therapies as medical treatment options, and the MEK1/2 inhibitor selumetinib has shown promising efficacy in pediatric patients with …

Personalized [177lu]Lutetium-Psma Therapy For Patients With Pre-Treated Castration-Resistant Prostate Cancer: A Single Institution Experience From A Comprehensive Cancer Centre, Wolfgang Thaiss, Friedemann Zengerling, Julia Friedrich, Veronika Hechler, Michael Grunert, Christian Bolenz, Thomas Wiegel, Ambros J Beer, Vikas Prasad

2020-Current year OA Pubs

Castration resistant prostate cancer (CRPC) is characterized by an aggressive biological behavior with a relatively short survival time, especially in progressive tumors pretreated with new hormonal agents and taxane chemotherapy. [177Lu]-Lutetium-PSMA (Lu-PSMA) treatment has proven efficacy in these patients. However, around 30% of the CRPC patients do not benefit from Lu-PSMA treatment, and little is known about predictive factors for treatment success if Lu-PSMA is offered in an individualized approach based on clinical and laboratory features. In this monocentric retrospective study, 86 CRPC patients receiving Lu-PSMA treatment were evaluated. The focus of the study was to describe clinical factors at …

The Upper And Lower Respiratory Tract Microbiome In Severe Aspiration Pneumonia, Georgios D Kitsios, Janet S Lee, Et Al.

2020-Current year OA Pubs

Uncertainty persists whether anaerobic bacteria represent important pathogens in aspiration pneumonia. In a nested case-control study of mechanically ventilated patients classified as macro-aspiration pneumonia (MAsP, n = 56), non-macro-aspiration pneumonia (NonMAsP, n = 91), and uninfected controls (n = 11), we profiled upper (URT) and lower respiratory tract (LRT) microbiota with bacterial 16S rRNA gene sequencing, measured plasma host-response biomarkers, analyzed bacterial communities by diversity and oxygen requirements, and performed unsupervised clustering with Dirichlet Multinomial Models (DMM). MAsP and NonMAsP patients had indistinguishable microbiota profiles by alpha diversity and oxygen requirements with similar host-response profiles and 60-day survival. Unsupervised DMM …

Transmembrane Stem Factor Nanodiscs Enhanced Revascularization In A Hind Limb Ischemia Model In Diabetic, Hyperlipidemic Rabbits, Eri Takematsu, Miles Massidda, Gretchen Howe, Julia Goldman, Patricia Felli, Lei Mei, Gregory Callahan, Andrew Sligar, Richard Smalling, Aaron Baker

Faculty, Staff and Student Publications

Therapies to revascularize ischemic tissue have long been a goal for the treatment of vascular disease and other disorders. Therapies using stem cell factor (SCF), also known as a c-Kit ligand, had great promise for treating ischemia for myocardial infarct and stroke, however clinical development for SCF was stopped due to toxic side effects including mast cell activation in patients. We recently developed a novel therapy using a transmembrane form of SCF (tmSCF) delivered in lipid nanodiscs. In previous studies, we demonstrated tmSCF nanodiscs were able to induce revascularization of ischemia limbs in mice and did not activate mast cells. …

First Line Acne Treatment: Comparison Of Cost And Efficacy, Michael P. Mcneil, Karlen E. Luthy, Christine R. Platt, Michael S. Robinson, Janelle L.B. Macintosh

Student Works

Acne vulgaris is a common skin concern that may cause permanent disfiguration and encumbering effects on self-esteem and mental health. Additionally, it is often associated with expensive treatment costs for patients. When selecting the most appropriate therapeutic approach, nurse practitioners must also consider the price of the medication. For the majority of mild to moderate cases of acne (both comedonal and inflammatory), effective first-line treatment recommendations include a combination of a topical retinoid, benzoyl peroxide, and a topical antibiotic such as clindamycin. Generic and compounded medications are typically more cost-effective for patients than brand name formulations.

Workers With Suspected Diagnosis Of Silicosis: A Case Study Of Sarcoidosis Versus Siderosis, Diemen Delgado-García, Patricio Miranda-Astorga, Ashley Delgado-Cano, Juan Gómez-Salgado, Carlos Ruiz-Frutos

School of Medicine Publications

Silicosis is one of the most important occupational respiratory diseases worldwide, hence the importance of making a correct diagnosis. Diagnosis is commonly based on radiological findings according to the ILO International Classification of Radiographs of Pneumoconioses and occupational exposure. High-resolution computed tomography is indicated for differential diagnosis. This article presents two cases with an initial diagnosis of silicosis that ended up being diagnosed as sarcoidosis and siderosis, respectively. The first case was a 42-year-old male who worked as a crushing operator in an underground copper and molybdenum mine for 22 years. He had a history of exposure to silicon dioxide …

Current Best Practice In Pelvic And Hip Fracture Management In The Older Adult Population, Anthony P. Joseph

Journal of Geriatric Emergency Medicine

Fractures of the pelvis and hip are a relatively frequent occurrence in the older population. Pelvic fractures in older patients usually occur after a fall from standing height. CT scan is the investigation of choice. There are several classifications available which are useful in risk stratification and predicting surgical treatment. Haemorrhage is a major complication and can usually be treated by interventional radiology. An Orthopedic opinion should be sought promptly, and surgical stabilisation (if indicated) should be completed as early as possible to enable early mobilisation and the avoidance of complications such as deep vein thrombosis or pneumonia.

Hip fractures …

Faculty, Staff and Students Publications

The emergence of antibiotic-resistant Acinetobacter baumannii strains with limited treatment options has become a significant global health concern. Efforts to develop vaccines against the bacteria have centred on several potential protein targets, including the TonB-dependent receptors (TBDRs). In the present study, TBDRs from A. baumannii were displayed on the surface of Bacillus subtilis spores. The immunogenicity of the recombinant spores was evaluated in orally vaccinated mice. None of the immunized mice demonstrated signs of illness and were observed to be healthy throughout the study. Sera and the intestinal secretions from the recombinant spores-treated mice demonstrated mucosal and humoral antibody responses …

Predicting Chemotherapy Benefit Across Different Races In Early-Stage Breast Cancer Patients Using The Oncotype Dx Score, Vikram R Shaw, Christopher I Amos, Chao Cheng

Faculty, Staff and Students Publications

Background: Oncotype DX assay, a multigene molecular test, has been widely used to stratify relapse risk and guide chemotherapy treatment in breast cancer. However, the optimal threshold of the Oncotype DX score in predicting chemotherapy benefit and its racial variation has not been investigated.

Methods: In this study, we apply a random forest survival model to the SEER-Oncotype cohort data (Surveillance, Epidemiology, and End Results with Oncotype DX test information for breast cancer patients) and determine chemotherapy benefit thresholds in early-stage, estrogen-receptor-positive (ER+), and HER2-negative (HER2-) patients of different races.

Results: Our results indicate that early-stage ER+, HER2-, and LN-/LN+ …

Intranasal Carbetocin Reduces Hyperphagia, Anxiousness, And Distress In Prader-Willi Syndrome: Care-Pws Phase 3 Trial, Elizabeth Roof, Cheri L Deal, Shawn E Mccandless, Ronald L Cowan, Jennifer L Miller, Jill K Hamilton, Elizabeth R Roeder, Shana E Mccormack, Tamanna R Roshan Lal, Hussein D Abdul-Latif, Andrea M Haqq, Kathryn S Obrynba, Laura C Torchen, Alaina P Vidmar, David H Viskochil, Jean-Pierre Chanoine, Carol K L Lam, Melinda J Pierce, Laurel L Williams, Lynne M Bird, Merlin G Butler, Diane E Jensen, Susan E Myers, Oliver J Oatman, Charumathi Baskaran, Laura J Chalmers, Cary Fu, Nathalie Alos, Scott D Mclean, Ajay Shah, Barbara Y Whitman, Brent A Blumenstein, Sarah F Leonard, Jessica P Ernest, Joseph W Cormier, Sara P Cotter, Davis C Ryman

Targeting Energy Intake And Circadian Biology To Engage Mechanisms Of Aging In Older Adults With Obesity: Calorie Restriction And Time-Restricted Eating, Satchidananda Panda, Geraldine Maier, Dennis T Villareal

Faculty, Staff and Students Publications

With the rise in obesity across age groups, it has been a hindrance to engaging in physical activity and mobility in older adults. Daily calorie restriction (CR) up to 25% has been the cornerstone of obesity management even though the safety in older adults remains incompletely understood. Although some adults can follow CR with clinically significant weight loss and improved health metrics, CR faces 2 obstacles-many fail to adopt CR and even among those who can adopt it short term, long-term compliance can be difficult. Furthermore, there is a continuing debate about the net benefits of CR-induced weight loss in …

Novel Potential Targets For Function-Promoting Therapies: Orphan Nuclear Receptors, Anti-Inflammatory Drugs, Troponin Activators, Mas Receptor Agonists, And Urolithin A, Waly Dioh, Vihang Narkar, Anurag Singh, Fady Malik, Luigi Ferrucci, Cendrine Tourette, Jean Mariani, Rob Van Maanen, Roger A Fielding

Faculty, Staff and Student Publications

In recent years, several new classes of therapies have been investigated with their potential for restoring or improving physical functioning in older adults. These have included Mas receptor agonists, regulators of mitophagy, skeletal muscle troponin activators, anti-inflammatory compounds, and targets of orphan nuclear receptors. The present article summarizes recent developments of the function-promoting effects of these exciting new compounds and shares relevant preclinical and clinical data related to their safety and efficacy. The development of novel compounds in this area is expanding and likely will need the advent of a new treatment paradigm for age-associated mobility loss and disability.

Sound-Category Learning And Memory Skills In Neurotypical Adults And Adults With Language-Learning Disabilities, Allison Fulcher

University Honors Theses

This study evaluates the impact of memory skills (procedural, declarative, and working) and sound discrimination abilities, on the ability of adults with and without Language Learning Disability (LLD) to learn two sound-category structures, one designed to be learned implicitly and the other designed to be learned explicitly. This design tests a theorized etiology for LLD, the Procedural Deficit Hypothesis (PDH), which posits that LLD is caused by selective impairments to procedural memory and implicit learning. It also serves to evaluate factors and conditions that contribute to success in second-language learning for adults, who are less neurologically suited to the task …

Advanced gastric adenocarcinoma (GAC) often leads to peritoneal carcinomatosis (PC) and is associated with very poor outcome. Here we report the comprehensive proteogenomic study of ascites derived cells from a prospective GAC cohort (n = 26 patients with peritoneal carcinomatosis, PC). A total of 16,449 proteins were detected from whole cell extracts (TCEs). Unsupervised hierarchical clustering resulted in three distinct groups that reflected extent of enrichment in tumor cells. Integrated analysis revealed enriched biological pathways and notably, some druggable targets (cancer-testis antigens, kinases, and receptors) that could be exploited to develop effective therapies and/or tumor stratifications. Systematic comparison of expression …

The Evolution Of Leadership During The Covid-19 Pandemic: An Analysis Of The Research, Luca Patrick Thierry Gregston

University Honors Theses

This paper's research question, "How has the COVID-19 pandemic changed the concept and practice of leadership? In the end much of the empirical evidence for what COVID-19 did or didn't change in leadership practices is still relatively ambiguous. So it is too early to say that "business as usual" is gone for good. And COVID furthered and deepened long term trends, accelerating the great resignation and a dramatic revaluation of intangible assets like reputation, intellectual property and human capital. In response, there is a clear need for a new leadership mindset for the 21st century after the COVID pandemic.

Reconceptualizing The Interaction Between Adhd Symptoms And Environmental Context, Oliver G. Mcfadden

University Honors Theses

Difficult questions regarding etiology, prevalence, and individual treatment allude to the heterogenous and complex neurocognitive profile ADHD. Current understandings do not point to there being any yet-undiscovered, succinct set of features for the condition that will answer these questions. ADHD in fact has a heterogeneous etiology and neurocognitive profile, suffers from both overdiagnosis and underdiagnosis, and a variety of styles of treatment are conceivable to address this. Sociocultural factors have crucially guided the direction of ADHD pathology and medicalization and are woven into institutional environments. These extant problems have eluded ADHD research, and the debate over the construction and validity …

Tattoos And Trauma: Are Tattoos Healing For Trauma?, Krystal Bell

University Honors Theses

Prior research and literature reviews suggest that there is medicinal value in tattooing for the healing of trauma. However, tattooing is still a burgeoning topic in academic studies and still mostly taboo as a western societal practice, so there are gaps in qualitative and quantitative data that could further validate the healing benefits of tattoos for trauma. This literature review analyzed 30 peer reviewed articles that focus on "contemporary tattoo data," "indigenous traditions and practices," "tattoos and trauma," and other alternative healing such as "MDMA, psilocybin, EMDR" to establish a well-rounded investigation into tattoos as an alternative healing option. The …

Pharmacogenetic Testing For The Pediatric Gastroenterologist: Actionable Drug-Gene Pairs To Know., Tracy L. Sandritter, Rachel Chevalier, Rebecca Abt, Valentina Shakhnovich

Manuscripts, Articles, Book Chapters and Other Papers

Gastroenterologists represent some of the earlier adopters of precision medicine through pharmacogenetic testing by embracing upfront genotyping for thiopurine S-methyltransferase nucleotide diphosphatase (TPMT) before prescribing 6-mercaptopurine or azathioprine for the treatment of inflammatory bowel disease. Over the last two decades, pharmacogenetic testing has become more readily available for other genes relevant to drug dose individualization. Common medications prescribed by gastroenterologists for conditions other than inflammatory bowel disease now have actionable guidelines, which can improve medication efficacy and safety; however, a clear understanding of how to interpret the results remains a challenge for many clinicians, precluding wide implementation of …

An Analysis Of State Sex Education Policies To Explore The Inclusiveness Of School Based Sex Education, Amarah Scott

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to analyze state policies related to sex education proposed between 2018 and 2022 to determine the extent to which sex education needs of LGBTQ youth were being addressed. Previous research has shown that, on average, both abstinence-only and comprehensive sex education curricula do not include information that is relevant to LGBTQ youth. Much of the information included in sex education curricula such as pregnancy prevention and the benefits and disadvantages of condoms are most relevant to youth who identify as heterosexual. Not receiving relevant and accurate sex education puts LGBTQ youth at risk for …

Aging is characterized by a decline in tissue function, but the underlying changes at cellular resolution across the organism remain unclear. Here, we present the Aging Fly Cell Atlas, a single-nucleus transcriptomic map of the whole aging Drosophila. We characterize 163 distinct cell types and perform an in-depth analysis of changes in tissue cell composition, gene expression, and cell identities. We further develop aging clock models to predict the fly age and show that ribosomal gene expression is a conserved predictive factor for age. Combining all aging features, we find unique cell type-specific aging patterns. This atlas provides a …

Loss Of Ampkα2 Promotes Melanoma Tumor Growth And Brain Metastasis, Ping Yuan, Da Teng, Evelyn De Groot, Man Li, Sebastian Trousil, Che-Hung Shen, Jason Roszik, Michael A Davies, Y N Vashisht Gopal, Bin Zheng

Faculty, Staff and Student Publications

AMP-activated protein kinase (AMPK) is a critical cellular energy sensor at the interface of metabolism and cancer. However, the role of AMPK in carcinogenesis remains unclear. Here, through analysis of the TCGA melanoma dataset, we found that PRKAA2 gene that encodes the α2 subunit of AMPK is mutated in ∼9% of cutaneous melanomas, and these mutations tend to co-occur with NF1 mutations. Knockout of AMPKα2 promoted anchorage-independent growth of NF1-mutant melanoma cells, whereas ectopic expression of AMPKα2 inhibited their growth in soft agar assays. Moreover, loss of AMPKα2 accelerated tumor growth of NF1-mutant melanoma and enhanced their brain …

Faculty, Staff and Student Publications

BACKGROUND AND AIMS: Widespread dysregulation of long non-coding RNAs [lncRNAs] including a reduction in GATA6-AS1 was noted in inflammatory bowel disease [IBD]. We previously reported a prominent inhibition of epithelial mitochondrial functions in ulcerative colitis [UC]. However, the connection between reduction of GATA6-AS1 expression and attenuated epithelial mitochondrial functions was not defined.

METHODS: Mucosal transcriptomics was used to conform GATA6-AS1 reduction in several treatment-naïve independent human cohorts [n=673]. RNA pull-down followed by mass spectrometry was used to determine the GATA6-AS1 interactome. Metabolomics and mitochondrial respiration following GATA6-AS1 silencing in Caco-2 cells were used to elaborate on GATA6-AS1 functions.

RESULTS: GATA6-AS1 …

Medicare Modernization—The Urgent Need For Fiscal Solvency, Brian J. Miller, Lisa M. Grabert, Eric D. Hargan

College of Nursing Faculty Research and Publications

Launched in 1965 based on the design prevalent in employer-sponsored insurance markets, Medicare began as a fee-for-service (FFS) benefit for the “very elderly,” with eligibility at age 65 years when the average life expectancy in the US was approximately 70 years. Fast forward to 2023, more than 60 million Americans depend on Medicare for financing their health benefits. Today, the program faces questions of fiscal sustainability, with hospital insurance (Part A) trust fund insolvency projected for 2028. Leaders across administrations, including former US Department of Health and Human Services Secretaries Burwell and Leavitt and former Center for Medicare & Medicaid …
