Department of Surgery Gibbon Society Historical Profiles

Women phsycians in the United States were virtually nonexistent in the early to mid-1800s. Traditional medical schools still did not accept women, and few secretarian or eclectic medical schools were beginning to open their doors to female students. In 1849 at Geneva College, Elizabeth Blackwell became the first woman to achieve a medical degree in the United States.1 At the time of the Civil War, the few women who had managed to obtain medical degrees mainly served as nurses in the war, because society was not yet ready to accept the female physician.2 Dr. Mary Edwards Walker would help change …

Discrimination Of Mild Cognitive Impairment And Alzheimer's Disease Using Transfer Entropy Measures Of Scalp Eeg, Joseph Mcbride, Xiaopeng Zhao, Nancy Munro, Gregory Jicha, Charles Smith, Yang Jiang

Sanders-Brown Center on Aging Faculty Publications

Mild cognitive impairment (MCI) is a neurological condition related to early stages of dementia including Alzheimer's disease (AD). This study investigates the potential of measures of transfer entropy in scalp EEG for effectively discriminating between normal aging, MCI, and AD participants. Resting EEG records from 48 age-matched participants (mean age 75.7 years)-15 normal controls, 16 MCI, and 17 early AD-are examined. The mean temporal delays corresponding to peaks in inter-regional transfer entropy are computed and used as features to discriminate between the three groups of participants. Three-way classification schemes based on binary support vector machine models demonstrate overall discrimination accuracies …

Combining Resources, Combining Forces: Regionalizing Hospital Library Services In A Large Statewide Health System., Heather J Martin, Basia Delawska-Elliott

Articles, Abstracts, and Reports

After a reduction in full-time equivalents, 2 libraries in large teaching hospitals and 2 libraries in small community hospitals in a western US statewide health system saw opportunity for expansion through a regional reorganization. Despite a loss of 2/3 of the professional staff and a budgetary decrease of 27% over the previous 3 years, the libraries were able to grow business, usage, awareness, and collections through organizational innovation and improved efficiency. This paper describes the experience--including process, challenges, and lessons learned--of an organizational shift to regionalized services, collections, and staffing. Insights from this process may help similar organizations going through …

Smallpox Vaccination Of Laboratory Workers At Us Variola Testing Sites, Sharon J. Medcalf, Laura Bilek, Teresa L. Hartman, Peter C. Iwen, Patricia Leuschen, Hannah Miller, Anne O'Keefe, Harlan Sayles, Philip W. Smith

Journal Articles: Epidemiology

To evaluate the need to revaccinate laboratory workers against smallpox, we assessed regular revaccination at the US Laboratory Response Network's variola testing sites by examining barriers to revaccination and the potential for persistence of immunity. Our data do not provide evidence to suggest prolonging the recommended interval for revaccination.

Sca-1+ Cells From Fetal Heart With High Aldehyde Dehydrogenase Activity Exhibit Enhanced Gene Expression For Self-Renewal, Proliferation, And Survival, Devaveena Dey, Guodong Pan, Nadimpalli R. S. Varma, Suresh S. Palaniyandi

Hypertension and Vascular Research Articles

Stem/progenitor cells from multiple tissues have been isolated based on enhanced activity of cytosolic aldehyde dehydrogenase (ALDH) enzyme. ALDH activity has emerged as a reliable marker for stem/progenitor cells, such that ALDH(bright/high) cells from multiple tissues have been shown to possess enhanced stemness properties (self-renewal and multipotency). So far though, not much is known about ALDH activity in specific fetal organs. In this study, we sought to analyze the presence and activity of the ALDH enzyme in the stem cell antigen-1-positive (Sca-1+) cells of fetal human heart. Biochemical assays showed that a subpopulation of Sca-1+ cells (15%) possess significantly high …

Dna Methylation In Humans And Dogs: Evaluating The Impact Of Nutritional And Particulate Exposures, Luke Benjamin Montrose

Graduate Student Theses, Dissertations, & Professional Papers

Asthma is among the most common chronic diseases in children, among the leading causes of hospitalization for children, and one of the leading causes of school absenteeism. Discovery of preventable factors and the underlying mechanisms that exacerbate asthma among prevalent cases is important for mitigating the health burden of this childhood disease. Environmental factors such as exposure to particulate matter (PM) or nutritional deficiencies can lead to poor respiratory health among susceptible children. Recent animal studies suggest that PM exposures and dietary nutrients may influence asthma pathways through epigenetic mechanisms. Epigenetic modifications are heritable changes that can regulate gene activity …

Hippocampal sclerosis of aging (HS-Aging) is a common high-morbidity neurodegenerative condition in elderly persons. To understand the risk factors for HS-Aging, we analyzed data from the Alzheimer’s Disease Genetics Consortium and correlated the data with clinical and pathologic information from the National Alzheimer’s Coordinating Center database. Overall, 268 research volunteers with HS-Aging and 2,957 controls were included; detailed neuropathologic data were available for all. The study focused on single-nucleotide polymorphisms previously associated with HS-Aging risk: rs5848 ( GRN ), rs1990622 ( TMEM106B ), and rs704180 ( ABCC9 ). Analyses of a subsample that was not previously evaluated (51 HS-Aging cases …

Stratification Of The Impact Of Inappropriate Empirical Antimicrobial Therapy For Gram-Negative Bloodstream Infections By Predicted Prognosis, Sarah E. Cain, Joseph Kohn, P. Brandon Bookstaver, Helmut Albrecht, Majdi N. Al-Hasan

Faculty Publications

The bloodstream infection mortality risk score (BSIMRS) predicts the outcome of patients with Gram-negative bloodstream infections (BSI) with high discrimination. This retrospective cohort study examined the impact of inappropriate antimicrobial therapy on mortality in adult patients with Gram-negative BSI admitted to Palmetto Health Hospitals in Columbia, SC, USA, from 1 January 2011 to 31 December 2012 after stratification by predicted prognosis at initial presentation using BSIMRS. A multivariate Cox regression model was used to identify independent risk factors for 28-day mortality overall and within each predefined BSIMRS category (<5, 5 to 9, and ≥10). Relative risk reduction (RRR), absolute risk reduction (ARR), and number needed to treat (NNT) were calculated from a predictive logistic regression model of mortality. Overall, 390 unique patients with first episodes of Gram-negative BSI were identified. The median age was 66 years, and 229 (59%) were women. There was significant association between inappropriate antimicrobial therapy and mortality in patients with BSIMRS of 5 to 9 (adjusted hazard ratio [aHR], 3.55; 95% confidence intervals [CI], 1.22 to 8.31; P = 0.02) and BSIMRS of ≥10 (aHR, 4.99; 95% CI, 1.09 to 22.87; P = 0.04) but not in those with BSIMRS of <5 (aHR, 3.34; 95% CI, 0.17 to 22.77; P = 0.34). RRR, ARR, and NNT were 0.25, 0.02, and 63 for BSIMRS of <5; 0.56, 0.32, and 3 for BSIMRS of 5 to 9; and 0.39, 0.39, and 3 for BSIMRS of ≥10, respectively. There is a significant benefit from appropriate antimicrobial therapy in patients with Gram-negative BSI with guarded (BSIMRS of 5 to 9) and poor (BSIMRS of ≥10) predicted prognosis. Survival difference remains unclear among those with good predicted prognosis (BSIMRS of <5) at initial presentation.

A Coding Variant In Tmc8 (Ever2) Is Associated With High Risk Hpv Infection And Head And Neck Cancer Risk, Caihua Liang, Karl T. Kelsey, Michael D. Mcclean, Brock C. Christensen, Carmen J. Marsit

Dartmouth Scholarship

HPV infection is a causal agent in many epithelial cancers, yet our understanding of genetic susceptibility to HPV infection and resultant cancer risk is limited. Epidermodysplasia Verruciformis is a rare condition of extreme susceptibility to cutaneous HPV infection primarily attributable to mutations in TMC6 and TMC8. Genetic variation in the TMC6/TMC8 region has been linked to beta-type HPV infection and squamous cell carcinoma of the skin, cervical cancer, HPV persistence and progression to cervical cancer. Here, we have tested the hypothesis that the common TMC8 SNP rs7208422 is associated with high-risk HPV infection and risk of head and neck …

Anti-Cancer Activity Of Withaferin A In B-Cell Lymphoma., M K Mckenna, B W Gachuki, S S Alhakeem, K N Oben, V M Rangnekar, R C Gupta, Subbarao Bondada

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Withaferin A (WA), a withanolide from the plant, Ashwagandha (Withania somnifera) used in Ayurvedic medicine, has been found to be valuable in the treatment of several medical ailments. WA has been found to have anticancer activity against various solid tumors, but its effects on hematological malignancies have not been studied in detail. WA strongly inhibited the survival of several human and murine B cell lymphoma cell lines. Additionally, in vivo studies with syngeneic-graft lymphoma cells suggest that WA inhibits the growth of tumor but does not affect other proliferative tissues. We demonstrate that WA inhibits the efficiency of NF-κB nuclear …

Fret Detection Of Lymphocyte Function-Associated Antigen-1 Conformational Extension, Alexandre Chigaev, Yelena Smagley, Mark K. Haynes, Oleg Ursu, Cristian G. Bologa, Liliana Halip, Tudor Oprea, Anna Waller, Mark B. Carter, Yinan Zhang, Wei Wang, Tione Buranda, Larry A. Sklar

Pharmaceutical Sciences Faculty Publications

Lymphocyte function-associated antigen 1 (LFA-1, CD11a/CD18, αLβ2-integrin) and its ligands are essential for adhesion between T-cells and antigen-presenting cells, formation of the immunological synapse, and other immune cell interactions. LFA-1 function is regulated through conformational changes that include the modulation of ligand binding affinity and molecular extension. However, the relationship between molecular conformation and function is unclear. Here fluorescence resonance energy transfer (FRET) with new LFA-1-specific fluorescent probes showed that triggering of the pathway used for T-cell activation induced rapid unquenching of the FRET signal consistent with extension of the molecule. Analysis of the FRET quenching at rest revealed an …

Background:

Acute kidney injury (AKI) occurs frequently after cardiac catheterization and percutaneous coronary intervention. Although a clinical risk model exists for percutaneous coronary intervention, no models exist for both procedures, nor do existing models account for risk factors prior to the index admission. We aimed to develop such a model for use in prospective automated surveillance programs in the Veterans Health Administration.

Methods and Results:

We collected data on all patients undergoing cardiac catheterization or percutaneous coronary intervention in the Veterans Health Administration from January 01, 2009 to September 30, 2013, excluding patients with chronic dialysis, end‐stage renal disease, renal …

Genome-Wide Scan For Methylation Profiles In Keloids, Lamont R. Jones, William Young, George W. Divine, Indrani Datta, Kang-Mei Chen, David M. Ozog, Maria Worsham

Otolaryngology Articles

Keloids are benign fibroproliferative tumors of the skin which commonly occur after injury mainly in darker skinned patients. Medical treatment is fraught with high recurrence rates mainly because of an incomplete understanding of the biological mechanisms that lead to keloids. The purpose of this project was to examine keloid pathogenesis from the epigenome perspective of DNA methylation. Genome-wide profiling used the Infinium HumanMethylation450 BeadChip to interrogate DNA from 6 fresh keloid and 6 normal skin samples from 12 anonymous donors. A 3-tiered approach was used to call out genes most differentially methylated between keloid and normal. When compared to normal, …

Endgame For Polio Eradication? Options For Overcoming Social And Political Factors In The Progress To Eradicating Polio., Pavan Ganapathiraju, Christiaan B Morssink, James D. Plumb

College of Population Health Faculty Papers

In 1988, the Global Polio Eradication Initiative (GPEI) was launched with the goal of eradicating polio by the year 2000. After 25 years, several dynamics still challenge this large public health campaign with new cases of polio being reported annually. We examine the roots of this initiative to eradicate polio, its scope, the successes and setbacks during the last 25 years and reflect on the current state of affairs. We examine the social and political factors that are barriers to polio eradication. Options are discussed for solving the current impasse of polio eradication: using force, respecting individual freedoms and gaining …

METHODS: Participants (N = 1,686) were 77% white, 62% female, aged 18-24 years (mean ± SD, 19.1 ± 1.1 years), and enrolled at 8 US universities. Body mass index (BMI) was calculated for self-report (via online survey); trained researchers measured height and weight and categorized them as normal (18.5 to < 25), overweight (25 to < 30), obese (30 to < 35), and morbidly obese (≥ 35).

RESULTS: Concordance of self-report vs objectively measured BMI groups using chi-square revealed that 93% were accurate, 4% were underestimated, and 2.7% were overestimated. Pearson correlations and adjusted linear regression revealed significant associations between self-report and measured …

Joint Impact Of Clinical And Behavioral Variables On The Risk Of Unplanned Readmission And Death After A Heart Failure Hospitalization, Badri Padhukasahasram, Chandan K. Reddy, Yan Li, David Lanfear

Cardiology Articles

Most current methods for modeling rehospitalization events in heart failure patients make use of only clinical and medications data that is available in the electronic health records. However, information about patient-reported functional limitations, behavioral variables and socio-economic background of patients may also play an important role in predicting the risk of readmission in heart failure patients. We developed methods for predicting the risk of rehospitalization in heart failure patients using models that integrate clinical characteristics with patient-reported functional limitations, behavioral and socio-economic characteristics. Our goal was to estimate the predictive accuracy of the joint model and compare it with models …

Mcl1 Enhances The Survival Of Cd8+ Memory T Cells After Viral Infection, Jingang Gui, Zhuting Hu, Ching-Yi Tsai, Tian Ma, Yan Song, Amanda Morales, Li-Hao Huang, Ethan Dmitrovsky, Ruth Craig, Edward Usherwood

Dartmouth Scholarship

Viral infection results in the generation of massive numbers of activated effector CD8+ T cells that recognize viral components. Most of these are short-lived effector T cells (SLECs) that die after clearance of the virus. However, a small proportion of this population survives and forms antigen-specific memory precursor effector cells (MPECs), which ultimately develop into memory cells. These can participate in a recall response upon reexposure to antigen even at protracted times postinfection. Here, antiapoptotic myeloid cell leukemia 1 (MCL1) was found to prolong survival upon T cell stimulation, and mice expressing human MCL1 as a transgene exhibited a skewing …

Public Health Sciences Articles

Height has an extremely polygenic pattern of inheritance. Genome-wide association studies (GWAS) have revealed hundreds of common variants that are associated with human height at genome-wide levels of significance. However, only a small fraction of phenotypic variation can be explained by the aggregate of these common variants. In a large study of African-American men and women (n = 14,419), we genotyped and analyzed 966,578 autosomal SNPs across the entire genome using a linear mixed model variance components approach implemented in the program GCTA (Yang et al Nat Genet 2010), and estimated an additive heritability of 44.7% (se: 3.7%) for this …

A Therapeutic Approach For Senile Dementias: Neuroangiogenesis, Charles T. Ambrose

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Alzheimer's disease (AD) and related senile dementias (SDs) represent a growing medical and economic crisis in this country. Apart from cautioning persons about risk factors, no practical, effective therapy is currently available. Much of the recent research in AD has been based on the amyloid cascade theory. Another approach assumes a vascular basis for SDs. This paper presents evidence from a score of studies that cerebral capillary density (CCD) declines during old age in animals and people as well as in AD. Neuroangiogenic (NAG) factors initiate and maintain capillaries in the brain. Thus a waning level of these factors and …

Journal Articles: Epidemiology

As the outbreak of Ebola virus disease (EVD) in West Africa continues, clinical preparedness is needed in countries at risk for EVD (e.g., United States) and more fully equipped and supported clinical teams in those countries with epidemic spread of EVD in Africa. Clinical staff must approach the patient with a very deliberate focus on providing effective care while assuring personal safety. To do this, both individual health care providers and health systems must improve EVD care. Although formal guidance toward these goals exists from the World Health Organization, Medecin Sans Frontières, the Centers for Disease Control and Prevention, and …

Neurosurgery

BACKGROUND: Genetic profiling represents the future of neuro-oncology but suffers from inadequate biopsies in heterogeneous tumors like Glioblastoma (GBM). Contrast-enhanced MRI (CE-MRI) targets enhancing core (ENH) but yields adequate tumor in only ~60% of cases. Further, CE-MRI poorly localizes infiltrative tumor within surrounding non-enhancing parenchyma, or brain-around-tumor (BAT), despite the importance of characterizing this tumor segment, which universally recurs. In this study, we use multiple texture analysis and machine learning (ML) algorithms to analyze multi-parametric MRI, and produce new images indicating tumor-rich targets in GBM.

METHODS: We recruited primary GBM patients undergoing image-guided biopsies and acquired pre-operative MRI: CE-MRI, Dynamic-Susceptibility-weighted-Contrast-enhanced-MRI, …
