Bipolar Disorder In Children (Including Gifted And 2e Children), Ed Malin

Graduate Student Independent Studies

Between the publication of the Diagnostic and Statistical Manual of Mental Disorders (DSM) in 1952 and the DSM-IV in 1993, 277 new disorders were created and made available for life-altering diagnoses. Should it be surprising that, since the late 1990s, psychiatrists in the United States have invented the diagnosis of Childhood-onset Bipolar Disorder? Common practice before that time (and still, in Europe) was that 18 was the earliest age of onset for Bipolar Disorder, based on extensive observation and family history. While lithium and anticonvulsants had been in use to treat adults with Bipolar Disorder, by the late 1990s children …

Autolysosomal Exocytosis Of Lipids Protect Neurons From Ferroptosis, Isha Ralhan, Jinlan Chang, Matthew J Moulton, Lindsey D Goodman, Nathanael Y J Lee, Greg Plummer, H Amalia Pasolli, Doreen Matthies, Hugo J Bellen, Maria S Ioannou

Faculty, Staff and Students Publications

During oxidative stress neurons release lipids that are internalized by glia. Defects in this coordinated process play an important role in several neurodegenerative diseases. Yet, the mechanisms of lipid release and its consequences on neuronal health are unclear. Here, we demonstrate that lipid-protein particle release by autolysosome exocytosis protects neurons from ferroptosis, a form of cell death driven by lipid peroxidation. We show that during oxidative stress, peroxidated lipids and iron are released from neurons by autolysosomal exocytosis which requires the exocytic machinery VAMP7 and syntaxin 4. We observe membrane-bound lipid-protein particles by TEM and demonstrate that these particles are …

Engaging Sleeplessness In Seattle At Clinical Site 1, Benjamin D. Masters, Luis Moreno Nunez, Ally Jo Veenhuizen, Kiana Rendorio

Nursing Leadership in Community Engagement Projects

Introduction

The National Library of Medicine notes an emerging area of research interest is the relationship between substance abuse and sleep (Mahfoud et al., 2009). According to the same 2007 National Survey on Drug Use and Health, “7.6 percent of Americans older than 12 years met the criteria for alcohol abuse or dependence” and goes on to highlight the mundanity of sleep disorder. Additionally, the 2008 National Sleep Foundation’s “Sleep in American” poll demonstrated “addicts in recovery are 5 to 10 times more likely to experience sleep disorders.” (Moufoud et al., 2009). Clinical Site 1 is an agency in Downtown …

Osteoporosis In The Setting Of Shoulder Arthroplasty: A Narrative Review, Mohammad Daher, Mohamad Fares, Peter Boufadel, Akshay Khanna, Ziad Zalaquett, Joseph A. Abboud

Rothman Institute Papers

Patients who undergo shoulder surgery are frequently affected by osteoporosis and osteopenia, and the prevalence of this association is expected to increase due to the growing number of elderly individuals undergoing these procedures. It may be advisable to conduct a preoperative DXA scan for orthopedic surgical candidates at high risk, to detect those who could benefit from early intervention and avoid any related adverse events. Some of these complications include periprosthetic fractures, infection, subsequent fragility fractures, and have an all-cause revision arthroplasty at 2 years post-op. Some studies analyzed the beneficence of antiresorptive medications pre-operatively but the latter did not …

The Arkansas Tuberculosis Sanatorium: Co-Memory And Intangible Cultural Heritage, Anita Ellyn Reddig

Student Theses and Dissertations

The Arkansas Tuberculosis Sanatorium opened in 1910 in rural Logan County, Arkansas in response to the devastating effects of tuberculosis. Designed exclusively for white Arkansans, the small group of wooden frame buildings grew into the largest tuberculosis sanatorium in our nation by the 1940s. The success of anti-tuberculosis medications and community outpatient treatment led to its closure in 1973. The Tangible Cultural Heritage (TCH) of the institution is evident in the remaining structures on the site of the former sanatorium. The Intangible Cultural Heritage (ICH) of the facility, however, is more difficult to commemorate because it is diverse and ubiquitous. …

Von Hippel-Lindau (VHL) disease is an autosomal dominant, inherited syndrome with variants in the VHL gene, causing predisposition to multi-organ neoplasms with vessel abnormality. Germline variants in VHL can be detected in 80-90% of patients clinically diagnosed with VHL disease. Here, we summarize the results of genetic tests for 206 Japanese VHL families, and elucidate the molecular mechanisms of VHL disease, especially in variant-negative unsolved cases. Of the 206 families, genetic diagnosis was positive in 175 families (85%), including 134 families (65%) diagnosed by exon sequencing (15 novel variants) and 41 (20%) diagnosed by multiplex ligation-dependent probe amplification (MLPA) (one …

Efficacy Of Externally Paced Training On Pain In Tendinopathy: A Systematic Review And Meta Analysis, Dylan Carmody, Alyssa Conanan, Daniel Moeller, Sarah Khoblall, Christopher Keating

Department of Physical Therapy Faculty Papers

Tendinopathy is a common condition with treatments focused on local tissue adaptations. Externally paced loading programs are designed to cue (visually, auditorily, or temporally) a person as to when to perform an exercise repetition during a set of repetitions. Externally paced loading programs propose central and peripheral changes with tendinopathy but conclusions regarding their efficacy on pain outcomes remain limited. Our review seeks to explore the efficacy of externally paced loading as a method to reduce self-reported pain in tendinopathic conditions. An electronic database search was conducted of PubMed, SPORTDiscus, Scopus, and CINAHL databases. A total of 2,104 studies were …

End-Of-Life Care In The Trauma Bay: Six Key Points, Louis Christie Dr

Journal of Geriatric Emergency Medicine

The dominant culture across North America, Europe and Australia has been characterized by workers in hospice and palliative care as ‘death denying’ or ‘death phobic’. The last two decades have seen a significant increase in the number of trauma patients with complex background co-morbidities due to advanced age. Effective end-of-life care in trauma requires physicians to begin careful, balanced and sensitive conversations encompassing goals of care and expectation-setting, in the trauma bay. These pointers will help the reader communicate the principles of these clinical decisions clearly to patients and their families.

Bk Channel Modulation By Positively Charged Peptides And Auxiliary Γ Subunits Mediated By The Ca2+-Bowl Site, Guanxing Chen, Qin Li, Timothy I Webb, Mark A Hollywood, Jiusheng Yan

Faculty, Staff and Student Publications

The large-conductance, Ca2+-, and voltage-activated K+ (BK) channel consists of the pore-forming α (BKα) subunit and regulatory β and γ subunits. The γ1-3 subunits facilitate BK channel activation by shifting the voltage-dependence of channel activation toward the hyperpolarization direction by about 50-150 mV in the absence of Ca2+. We previously found that the intracellular C-terminal positively charged regions of the γ subunits play important roles in BK channel modulation. In this study, we found that the intracellular C-terminal region of BKα is indispensable in BK channel modulation by the γ1 subunit. Notably, synthetic peptide mimics of the γ1-3 subunits' C-terminal …

This work aimed to discuss different approaches and produce guidance on evaluating RAS. Methods: A consensus conference research methodology was adopted. A panel of 14 experts was assembled …

Bronchopulmonary Dysplasia: Ongoing Challenges From Definitions To Clinical Care, Sushma Nuthakki, Kaashif Ahmad, Gloria Johnson, Milenka Cuevas Guaman

Faculty, Staff and Students Publications

Bronchopulmonary dysplasia (BPD) is the most common complication of extreme prematurity. Its etiology is multifactorial and is attributed to genetic susceptibility to prenatal and postnatal factors. As advancements in neonatology have led to the increased survival of premature infants, a parallel increase in the incidence of BPD has occurred. Over time, the definition and diagnostic criteria for BPD have evolved, as have management strategies. However, challenges continue to exist in the management of these infants, which is not surprising given the complexity of the disease. We summarize the key diagnostic criteria and provide insight into the challenges related to various …

DNA methylation acts as a major epigenetic modification in mammals, characterized by the transfer of a methyl group to a cytosine. DNA methylation plays a pivotal role in regulating normal development, and misregulation in cells leads to an abnormal phenotype as is seen in several cancers. Any mutations or expression anomalies of genes encoding regulators of DNA methylation may lead to abnormal expression of critical molecules. A comprehensive genomic study encompassing all the genes related to DNA methylation regulation in relation to breast cancer is lacking. We used genomic and transcriptomic datasets from the Cancer Genome Atlas (TGCA) Pan-Cancer Atlas, …

Tumor-associated macrophages (TAMs) are abundant in pancreatic ductal adenocarcinomas (PDACs). While TAMs are known to proliferate in cancer tissues, the impact of this on macrophage phenotype and disease progression is poorly understood. We showed that in PDAC, proliferation of TAMs could be driven by colony stimulating factor-1 (CSF1) produced by cancer-associated fibroblasts. CSF1 induced high levels of p21 in macrophages, which regulated both TAM proliferation and phenotype. TAMs in human and mouse PDACs with high levels of p21 had more inflammatory and immunosuppressive phenotypes. p21 expression in TAMs was induced by both stromal interaction and/or chemotherapy treatment. Finally, by modeling …

Using the structure of gliotoxin as a starting point, we have prepared two different chemotypes with selective affinity to the kappa opioid receptor (KOR). Using medicinal chemistry approaches and structure-activity relationship (SAR) studies, structural features required for the observed affinity were identified, and advanced molecules with favorable Multiparameter Optimization (MPO) and Ligand Lipophilicity (LLE) profiles were prepared. Using the Thermal Place Preference Test (TPPT), we have shown that compound2 blocks the antinociceptive effect of U50488, a known KOR agonist. Multiple reports suggest that modulation of KOR signaling is a promising therapeutic strategy in treating neuropathic pain (NP). As a …

Faculty, Staff and Student Publications

Background: Risk-reducing salpingectomy with delayed oophorectomy has gained interest for individuals at high risk for tubo-ovarian cancer as there is compelling evidence that especially high-grade serous carcinoma originates in the fallopian tubes. Two studies have demonstrated a positive effect of salpingectomy on menopause-related quality of life and sexual health compared with standard risk-reducing salpingo-oophorectomy.

Primary objective: To investigate whether salpingectomy with delayed oophorectomy is non-inferior to the current standard salpingo-oophorectomy for the prevention of tubo-ovarian cancer among individuals at high inherited risk.

Study hypothesis: We hypothesize that postponement of oophorectomy after salpingectomy, to the age of 40-45 (BRCA1) …

Mitotrace: A Computational Framework For Analyzing Mitochondrial Variation In Single-Cell Rna Sequencing Data, Mingqiang Wang, Wankun Deng, David C Samuels, Zhongming Zhao, Lukas M Simon

Faculty, Staff and Student Publications

Genetic variation in the mitochondrial genome is linked to important biological functions and various human diseases. Recent progress in single-cell genomics has established single-cell RNA sequencing (scRNAseq) as a popular and powerful technique to profile transcriptomics at the cellular level. While most studies focus on deciphering gene expression, polymorphisms including mitochondrial variants can also be readily inferred from scRNAseq. However, limited attention has been paid to investigate the single-cell landscape of mitochondrial variants, despite the rapid accumulation of scRNAseq data in the community. In addition, a diploid context is assumed for most variant calling tools, which is not appropriate for …

The Role Of Native Cysteine Residues In The Oligomerization Of Kcnq1 Channels, Alison Bates, Rebecca B Stowe, Elizabeth M Travis, Lauryn E Cook, Carole Dabney-Smith, Gary A Lorigan

Faculty, Staff and Student Publications

KCNQ1, the major component of the slow-delayed rectifier potassium channel, is responsible for repolarization of cardiac action potential. Mutations in this channel can lead to a variety of diseases, most notably long QT syndrome. It is currently unknown how many of these mutations change channel function and structure on a molecular level. Since tetramerization is key to proper function and structure of the channel, it is likely that mutations modify the stability of KCNQ1 oligomers. Presently, the C-terminal domain of KCNQ1 has been noted as the driving force for oligomer formation. However, truncated versions of this protein lacking the C-terminal …
