Household Wealth And Neurocognitive Development Disparities Among School-Aged Children In Nepal., Shivani A Patel, Laura E Murray-Kolb, Steven C Leclerq, Subarna K Khatry, James M. Tielsch, Joanne Katz, Parul Christian

Global Health Faculty Publications

BACKGROUND: Wealth disparities in child developmental outcomes are well documented in developed countries. We sought to (1) describe the extent of wealth-based neurocognitive development disparities and (2) examine potential mediating factors of disparities among a population-based cohort of children in rural Nepal.

METHODS: We investigated household wealth-based differences in intellectual, executive and motor function of n = 1692 children aged between 7 and 9 years in Nepal. Using linear mixed models, wealth-based differences were estimated before and after controlling for child and household demographic characteristics. We further examined wealth-based differences adjusted for three sets of mediators: child nutritional status, home …

Clinical Phenotypes And Abcc6 Gene Mutations In Brazilian Families With Pseudoxanthoma Elasticum., Caroline Silvério Faria, Qiaoli Li, Haitao Guo, Jouni Uitto, Sylvia Satomi Takeno, Marilia De Arruda Cardoso Smith, Dertia Villalba Freire-Maia

Department of Dermatology and Cutaneous Biology Faculty Papers

Pseudoxanthoma elasticum (PXE; OMIM 264800) manifests with characteristic skin lesions of yellowish papules which coalesce into plaques of inelastic and leathery skin on the predilection sites (1). The ocular findings consist of angioid streaks, choroidal neovascularization and subretinal hemorrhages resulting in loss of visual acuity and occasional blindness. Cardiovascular problems include hypertension, intermittent claudication, and occasional myocardial infarcts and stroke. The prevalence of PXE is estimated to be in the range of 1:50,000-70,000 and to be more frequent in females than in males. The diagnosis can be challenging to clinicians due to late-onset of clinical manifestations and considerable heterogeneity. PXE …

Department of Medical Oncology Faculty Papers

Over the past decades, some scientific progress has been made in understanding and treating cancer-related fatigue (CRF). However, three major problems have limited further progress: lack of agreement about measurement, inadequate understanding of the underlying biology, and problems in the conduct of clinical trials for CRF. This commentary reports the recommendations of a National Cancer Institute Clinical Trials Planning Meeting and an ongoing National Cancer Institute working group to address these problems so that high-priority research and clinical trials can be conducted to advance the science of CRF and its treatment. Recommendations to address measurement issues included revising the current …

Randomized Clinical Trial Examining Duration Of Voucher-Based Reinforcement Therapy For Cocaine Abstinence., Kimberly C Kirby, Carolyn M Carpenedo, Karen L Dugosh, Beth J Rosenwasser, Lois A Benishek, Alicia Janik, Rachel Keashen, Elena Bresani, Kenneth Silverman

College of Science & Mathematics Departmental Research

BACKGROUND: This is the first study to systematically manipulate duration of voucher-based reinforcement therapy (VBRT) to see if extending the duration increases abstinence during and following VBRT.

METHODS: We randomized cocaine-dependent methadone-maintained adults to Standard (12 weeks; n=62) or Extended (36 weeks; n=68) VBRT and provided escalating voucher amounts contingent upon urinalysis verification of cocaine abstinence. Urinalysis was scheduled at least every 2 weeks during the 48-week study and more frequently during VBRT (3/week) and 12 weeks of Aftercare (2/week).

RESULTS: Extended VBRT produced longer durations of continuous cocaine abstinence during weeks 1-24 (5.7 vs 2.7 weeks; p=0.003) and proportionally …

Increased Abundance Of Frost Mrna During Recovery From Cold Stress Is Not Essential For Cold Tolerance In Adult Drosophila Melanogaster., H Udaka, A Percival-Smith, B J Sinclair

Biology Publications

Frost (Fst) is a candidate gene associated with the response to cold in Drosophila melanogaster because Fst mRNA accumulation increases during recovery from low temperature exposure. We investigated the contribution of Fst expression to chill-coma recovery time, acute cold tolerance and rapid cold hardening (RCH) in adult D. melanogaster by knocking down Fst mRNA expression using GAL4/UAS-mediated RNA interference. In this experiment, four UAS-Fst and one tubulin-GAL4 lines were used. We predicted that if Fst is essential for cold tolerance phenotypes, flies with low Fst mRNA levels should be less cold tolerant than flies with normal levels of cold-induced Fst …

A Population-Based Case–Control Study Of Urinary Arsenic Species And Squamous Cell Carcinoma In New Hampshire, Usa, Diane Gilbert-Diamond, Zhigang Li, Ann E. Perry, Steven K. Spencer, A Jay Gandolfi, Margaret R. Karagas

Dartmouth Scholarship

Background: Chronic high arsenic exposure is associated with squamous cell carcinoma (SCC) of the skin, and inorganic arsenic (iAs) metabolites may play an important role in this association. However, little is known about the carcinogenicity of arsenic at levels commonly observed in the United States.

Objective: We estimated associations between total urinary arsenic and arsenic species and SCC in a U.S. population.

Methods: We conducted a population-based case–control SCC study (470 cases, 447 controls) in a U.S. region with moderate arsenic exposure through private well water and diet. We measured urinary iAs, monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA), and …

Impact Of Treatment Response Metrics On Photodynamic Therapy Planning And Outcomes In A Three-Dimensional Model Of Ovarian Cancer, Sriram Anbil, Imran Rizvi, Jonathan P. Celli, Nermina Alagic, Brian W. Pogue, Tayyaba Hasan

Dartmouth Scholarship

Common methods to characterize treatment efficacy based on morphological imaging may misrepresent outcomes and exclude effective therapies. Using a three-dimensional model of ovarian cancer, two functional treatment response metrics are used to evaluate photodynamic therapy (PDT) efficacy: total volume, calculated from viable and nonviable cells, and live volume, calculated from viable cells. The utility of these volume-based metrics is corroborated using independent reporters of photodynamic activity: viability, a common fluorescence-based ratiometric analysis, and photosensitizer photobleaching, which is characterized by a loss of fluorescence due in part to the production of reactive species during PDT. Live volume correlated with both photobleaching …

Ultrasonic Incisions Produce Less Inflammatory Mediator Response During Early Healing Than Electrosurgical Incisions., Bindu Nanduri, Ken Pendarvis, Leslie A. Shack, Ranjit Kumar, Jeffrey W. Clymer, Donna L. Korvick, Shane C. Burgess

CVM Publications

As the use of laparoscopic surgery has become more widespread in recent years, the need has increased for minimally-invasive surgical devices that effectively cut and coagulate tissue with reduced tissue trauma. Although electrosurgery (ES) has been used for many generations, newly-developed ultrasonic devices (HARMONIC? Blade, HB) have been shown at a macroscopic level to offer better coagulation with less thermally-induced tissue damage. We sought to understand the differences between ES and HB at a microscopic level by comparing mRNA transcript and protein responses at the 3-day timepoint to incisions made by the devices in subcutaneous fat tissue in a porcine …

The Flexible Fairness: Equality, Earned Entitlement, And Self-Interest, Chunliang Feng, Yi Luo, Ruolei Gu, Lucas S. Broster, Xueyi Shen, Tengxiang Tian, Yue-Jia Luo, Frank Krueger

Behavioral Science Faculty Publications

The current study explored whether earned entitlement modulated the perception of fairness in three experiments. A preliminary resource earning task was added before players decided how to allocate the resource they jointly earned. Participants' decision in allocation, their responses to equal or unequal offers, whether advantageous or disadvantageous, and subjective ratings of fairness were all assessed in the current study. Behavioral results revealed that participants proposed more generous offers and showed enhanced tolerance to disadvantageous unequal offers from others when they performed worse than their presumed "partners," while the reverse was true in the better-performance condition. The subjective ratings also …

Aspirin And Low-Molecular Weight Heparin Combination Therapy Effectively Prevents Recurrent Miscarriage In Hyperhomocysteinemic Women., Pratip Chakraborty, Sayani Banerjee, Piyali Saha, Shyam Sundar Nandi, Sunita Sharma, Sourendra K. Goswami, Baidyanath Chakravarty, Syed N. Kabir

Journal Articles: Cellular & Integrative Physiology

The management of recurrent pregnancy loss (RPL) still remains a great challenge, and women with polycystic ovarian syndrome (PCOS) are at a greater risk for spontaneous abortion. Treatment with low-molecular-weight heparin (LMWH) has become an accepted treatment option for women with RPL; however, the subgroup of women, who are likely to respond to LMWH, has not been precisely identified. The present study evaluated the efficacy of LMWH with reference to PCOS and associated metabolic phenotypes including hyperhomocysteinemia (HHcy), insulin resistance (IR) and obesity. This prospective observational study was conducted at Institute of Reproductive Medicine, Kolkata, India. A total of 967 …

Patterning In Placental 11-B Hydroxysteroid Dehydrogenase Methylation According To Prenatal Socioeconomic Adversity, Allison A. Appleton, David A. Armstrong, Corina Lesseur, Joyce Lee, James F. Padbury, Barry M. Lester

Dartmouth Scholarship

Background:

Prenatal socioeconomic adversity as an intrauterine exposure is associated with a range of perinatal outcomes although the explanatory mechanisms are not well understood. The development of the fetus can be shaped by the intrauterine environment through alterations in the function of the placenta. In the placenta, the HSD11B2 gene encodes the 11-beta hydroxysteroid dehydrogenase enzyme, which is responsible for the inactivation of maternal cortisol thereby protecting the developing fetus from this exposure. This gene is regulated by DNA methylation, and this methylation and the expression it controls has been shown to be susceptible to a variety of stressors from …

The Perceived Role Of Biological Father Contact In The Self-Estem Development Of Young African American Women : An Exploratory Study, Kendra R. Archer

Theses, Dissertations, and Projects

This qualitative study was designed to explore how young self-identified women of African American and African descent describe the connection between their father-daughter relationships and their self-esteem development. This exploratory study presents findings and narratives from the perspectives of 14 self-identified women of African American and African descent between the ages of 22- 30 who had face-to face contact with their biological fathers for at least five years throughout their lives. It was expected that the African American women in this study would speak to their experiences of paternal love or rejection in ways, which were tied positively or negatively …

Cyclin D1 Determines Estrogen Signaling In The Mammary Gland In Vivo., Mathew C Casimiro, Chenguang Wang, Z Li, Gabriele Disante, Nicole E Willmart, Sankar Addya, Lei Chen, Yang Liu, Michael P. Lisanti, Richard Pestell

Department of Cancer Biology Faculty Papers

The CCND1 gene, which is frequently overexpressed in cancers, encodes the regulatory subunit of a holoenzyme that phosphorylates the retinoblastoma protein. Although it is known that cyclin D1 regulates estrogen receptor (ER)α transactivation using heterologous reporter systems, the in vivo biological significance of cyclin D1 to estrogen-dependent signaling, and the molecular mechanisms by which cyclin D1 is involved, are yet to be elucidated. Herein, genome-wide expression profiling conducted of 17β-estradiol-treated castrated virgin mice deleted of the Ccnd1 gene demonstrated that cyclin D1 determines estrogen-dependent gene expression for 88% of estrogen-responsive genes in vivo. In addition, expression profiling of 17β-estradiol-stimulated cyclin …

Stress-Inducible Phosphoprotein 1 Has Unique Cochaperone Activity During Development And Regulates Cellular Response To Ischemia Via The Prion Protein., Flavio H Beraldo, Iaci N Soares, Daniela F Goncalves, Jue Fan, Anu A Thomas, Tiago G Santos, Amro H Mohammad, Martin Roffé, Michele D Calder, Simona Nikolova, Glaucia N Hajj, Andre L Guimaraes, Andre R Massensini, Ian Welch, Dean H Betts, Robert Gros, Maria Drangova, Andrew J Watson, Robert Bartha, Vania F Prado, Vilma R Martins, Marco A M Prado

Obstetrics & Gynaecology Publications

Stress-inducible phosphoprotein 1 (STI1) is part of the chaperone machinery, but it also functions as an extracellular ligand for the prion protein. However, the physiological relevance of these STI1 activities in vivo is unknown. Here, we show that in the absence of embryonic STI1, several Hsp90 client proteins are decreased by 50%, although Hsp90 levels are unaffected. Mutant STI1 mice showed increased caspase-3 activation and 50% impairment in cellular proliferation. Moreover, placental disruption and lack of cellular viability were linked to embryonic death by E10.5 in STI1-mutant mice. Rescue of embryonic lethality in these mutants, by transgenic expression of the …

The Effect Of Malnutrition On Patients Undergoing Elective Joint Arthroplasty., Ronald Huang, Md, Max Greenky, Bs, Glenn J. Kerr, Md, Mathew S. Austin, Md, Javad Parvizi, Md, Frcs

Rothman Institute Papers

Malnutrition has been linked to serious complications in patients undergoing elective total joint arthroplasty (TJA). This study prospectively evaluated 2,161 patients undergoing elective TJA for malnutrition as defined by either an abnormal serum albumin or transferrin. The overall incidence of malnutrition was 8.5% (184 of 2,161) and the rate of overall complications in the malnourished group was 12% as compared to 2.9% in patients with normal parameters (P55years-old undergoing TJA and is associated with a significant increase in post-operative complications.

Equivalence Of Students' Scores On Timed And Untimed Anatomy Practical Examinations., Guiyan Zhang, Bruce Fenderson, Richard R Schmidt, J J. Veloski

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Untimed examinations are popular with students because there is a perception that first impressions may be incorrect, and that difficult questions require more time for reflection. In this report, we tested the hypothesis that timed anatomy practical examinations are inherently more difficult than untimed examinations. Students in the Doctor of Physical Therapy program at Thomas Jefferson University were assessed on their understanding of anatomic relationships using multiple-choice questions. For the class of 2012 (n = 46), students were allowed to circulate freely among 40 testing stations during the 40-minute testing session. For the class of 2013 (n = 46), students …

Self-Regulatory Depletion Increases Emotional Reactivity In The Amygdala, Dylan D. Wagner, Todd F. Heatherton

Dartmouth Scholarship

The ability to self-regulate can become impaired when people are required to engage in successive acts of effortful self-control, even when self-control occurs in different domains. Here, we used functional neuroimaging to test whether engaging in effortful inhibition in the cognitive domain would lead to putative dysfunction in the emotional domain. Forty-eight participants viewed images of emotional scenes during functional magnetic resonance imaging in two sessions that were separated by a challenging attention control task that required effortful inhibition (depletion group) or not (control group). Compared to the control group, depleted participants showed increased activity in the left amygdala to …

Tricellulin Deficiency Affects Tight Junction Architecture And Cochlear Hair Cells, Gowri Nayak, Sue I. Lee, Rizwan Yousaf, Stephanie E. Edelmann, Claire Trincot, Christina M. Van Itallie, Ghanshyam P. Sinha, Maria Rafeeq, Sherri M. Jones, Inna A. Belyantseva, James M. Anderson, Andrew Forge, Gregory I. Frolenkov, Saima Riazuddin

Physiology Faculty Publications

The two compositionally distinct extracellular cochlear fluids, endolymph and perilymph, are separated by tight junctions that outline the scala media and reticular lamina. Mutations in TRIC (also known as MARVELD2), which encodes a tricellular tight junction protein known as tricellulin, lead to nonsyndromic hearing loss (DFNB49). We generated a knockin mouse that carries a mutation orthologous to the TRIC coding mutation linked to DFNB49 hearing loss in humans. Tricellulin was absent from the tricellular junctions in the inner ear epithelia of the mutant animals, which developed rapidly progressing hearing loss accompanied by loss of mechanosensory cochlear hair cells, while …

Differential Dna Methylation In Umbilical Cord Blood Of Infants Exposed To Low Levels Of Arsenic In Utero, Devin C. Koestler, Michele Avissar-Whiting, E. Andres Houseman, Margaret R. Karagas, Carmen J. Marsit

Dartmouth Scholarship

Background: There is increasing epidemiologic evidence that arsenic exposure in utero, even at low levels found throughout much of the world, is associated with adverse reproductive outcomes and may contribute to long-term health effects. Animal models, in vitro studies, and human cancer data suggest that arsenic may induce epigenetic alterations, specifically by altering patterns of DNA methylation.

Objectives: In this study we aimed to identify differences in DNA methylation in cord blood samples of infants with in utero, low-level arsenic exposure.

Methods: DNA methylation of cord-blood derived DNA from 134 infants involved in a prospective birth cohort in …

Estradiol Regulation Of Nucleotidases In Female Reproductive Tract Epithelial Cells And Fibroblasts, Zheng Shen, John V. Fahey, Jack E. Bodwell, Marta Rodriguez-Garcia, Richard M. Rossoll, Sarah G. Crist, Mickey V. Patel, Charles R. Wira

Dartmouth Scholarship

The use of topical and oral adenosine derivatives in HIV prevention that need to be maintained in tissues and cells at effective levels to prevent transmission prompted us to ask whether estradiol could influence the regulation of catabolic nucleotidase enzymes in epithelial cells and fibroblasts from the upper and lower female reproductive tract (FRT) as these might affect cellular TFV-DP levels. Epithelial cells and fibroblasts were isolated from endometrium (EM), endocervix (CX) and ectocervix (ECX) tissues from hysterectomy patients, grown to confluence and treated with or without estradiol prior to RNA isolation. The expression of nucleotidase (NT) genes was measurable …

Sepsis is a common cause of death, but outcomes in individual patients are difficult to predict. Elucidating the molecular processes that differ between sepsis patients who survive and those who die may permit more appropriate treatments to be deployed. We examined the clinical features and the plasma metabolome and proteome of patients with and without community-acquired sepsis, upon their arrival at hospital emergency departments and 24 hours later. The metabolomes and proteomes of patients at hospital admittance who would ultimately die differed markedly from those of patients who would survive. The different profiles of proteins and metabolites clustered into the …

Population Cancer Risks Associated With Coal Mining: A Systematic Review, Wiley D. Jenkins, W. Jay Christian, Georgia Mueller, K. Thomas Robbins

Epidemiology and Environmental Health Faculty Publications

BACKGROUND: Coal is produced across 25 states and provides 42% of US energy. With production expected to increase 7.6% by 2035, proximate populations remain at risk of exposure to carcinogenic coal products such as silica dust and organic compounds. It is unclear if population exposure is associated with increased risk, or even which cancers have been studied in this regard.

METHODS: We performed a systematic review of English-language manuscripts published since 1980 to determine if coal mining exposure was associated with increased cancer risk (incidence and mortality).

RESULTS: Of 34 studies identified, 27 studied coal mining as an occupational exposure …

Dartmouth Scholarship

Epithelial ovarian cancer (EOC) has a heritable component that remains to be fully characterized. Most identified common susceptibility variants lie in non-protein-coding sequences. We hypothesized that variants in the 3 ′ untranslated region at putative microRNA (miRNA) binding sites represent functional targets that influence EOC susceptibility. Here, we evaluate the association between 767 miRNA binding site single nucleotide polymorphisms (miRSNPs) and EOC risk in 18,174 EOC cases and 26,134 controls from 43 studies genotyped through the Collaborative Oncological Gene-environment Study. We identify several miRSNPs associated with invasive serous EOC risk (OR=1.12, P =10⁻⁸ ) mapping to an inversion polymorphism …

Dartmouth Scholarship

Background: Aberrant DNA methylation is a prominent feature of many cancers, and may be especially relevant in germ cell tumors (GCTs) due to the extensive epigenetic reprogramming that occurs in the germ line during normal development. Methods: We used the Illumina GoldenGate Cancer Methylation Panel to compare DNA methylation in the three main histologic subtypes of pediatric GCTs (germinoma, teratoma and yolk sac tumor (YST); N = 51) and used recursively partitioned mixture models (RPMM) to test associations between methylation pattern and tumor and demographic characteristics. We identified genes and pathways that were differentially methylated using generalized linear models and …

Population and Public Health Sciences Faculty Publications

Objective:To systematically examine infant size and growth, according to the 2006 WHO infant growth standards, as risk factors for overweight status in young adulthood in a historical cohort. Specifically, to assess: Whether accounting for length (weight-for-length) provides a different picture of risk than weight-for-age, intervals of rapid growth in both weight-for-age and weight-for-length metrics, and what particular target ages for infant size and intervals of rapid growth associate most strongly with overweight as a young adult.Patients/Methods:Data analysis of 422 appropriate for gestational age white singleton infants enrolled in the Fels Longitudinal Study. Odds ratios (OR) for overweight and obesity in …

B Cell Response And Hemagglutinin Stalk-Reactive Antibody Production In Different Age Cohorts Following 2009 H1n1 Influenza Virus Vaccination, Mark Y. Sangster, Jane Baer, Felix W. Santiago, Theresa T. Fitzgerald, Natalia A. Ilyushina

Dartmouth Scholarship

The 2009 pandemic H1N1 (pH1N1) influenza virus carried a swine-origin hemagglutinin (HA) that was closely related to the HAs of pre-1947 H1N1 viruses but highly divergent from the HAs of recently circulating H1N1 strains. Consequently, prior ex- posure to pH1N1-like viruses was mostly limited to individuals over the age of about 60 years. We related age and associated dif- ferences in immune history to the B cell response to an inactivated monovalent pH1N1 vaccine given intramuscularly to subjects in three age cohorts: 18 to 32 years, 60 to 69 years, and >70 years. The day 0 pH1N1-specific hemagglutination inhibition (HAI) …

Significant Sequelae After Bacterial Meningitis In Niger: A Cohort Study, Jean-François Jusot, Zilahatou Tohon, Abdoul Aziz Yazi, Jean-Marc Collard

Epidemiology and Environmental Health Faculty Publications

BACKGROUND: Beside high mortality, acute bacterial meningitis may lead to a high frequency of neuropsychological sequelae. The Sahelian countries belonging to the meningitis belt experience approximately 50% of the meningitis cases occurring in the world. Studies in Africa have shown that N. meningitidis could cause hearing loss in up to 30% of the cases, exceeding sometimes measles. The situation is similar in Niger which experiences yearly meningitis epidemics and where rehabilitation wards are rare and hearing aids remain unaffordable. The aim of this study was to estimate the frequency of neuropsychological sequelae after acute bacterial meningitis in four of the …
