NYMC Faculty Publications

Using the Center for International Blood and Marrow Transplant Research (CIBMTR) registry, we analyzed 1404 umbilical cord bloodtransplantation (UCBT) patients (single (<18 years)=810, double (⩾18 years)=594) with acute leukemia to define the incidence of acuteGvHD (aGvHD) and chronic GvHD (cGvHD), analyze clinical risk factors and investigate outcomes. After single UCBT, 100-day incidence of grade II-IV aGvHD was 39% (95% confidence interval (CI), 36-43%), grade III-IV aGvHD was 18% (95% CI, 15-20%) and 1-year cGvHD was 27% (95% CI, 24-30%). After double UCBT, 100-day incidence of grade II-IV aGvHD was 45% (95% CI, 41-49%), grade III-IV aGvHD was 22% (95% CI, 19-26%) and …

Joint Spatial Time Series Epidemiological Analysis Of Malaria And Cutaneous Leishmaniasis Infection, O. A. Adegboye, M. Al-Saghir, Denis H. Y. Leung

Research Collection School Of Economics

Malaria and leishmaniasis are among the two most important health problems of many developing countries especially in the Middle East and North Africa. It is common for vector-borne infectious diseases to have similar hotspots which may be attributed to the overlapping ecological distribution of the vector. Hotspot analyses were conducted to simultaneously detect the location of local hotspots and test their statistical significance. Spatial scan statistics were used to detect and test hotspots of malaria and cutaneous leishmaniasis (CL) in Afghanistan in 2009. A multivariate negative binomial model was used to simultaneously assess the effects of environmental variables on malaria …

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Antibiotic stewardship programs (ASP) improve appropriate antibiotic use. Data are limited on the clinical benefit of ASPs in children's hospitals. This study's objective was to determine the impact of an ASP on length of stay (LOS) and readmission rate among patients admitted to children's hospitals.

METHODS: Data from a prospective-audit-with-feedback ASP were used to examine the ASP review characteristics, including antibiotic(s) prescribed, clinical indication, recommendations made by the ASP, and agreement with recommendations. Propensity score analysis was utilized to determine the impact of the ASP on LOS and 30-day readmission based on whether the patient received an ASP recommendation …

Parvovirus B19 Ns1 Protein Induces Cell Cycle Arrest At G2-Phase By Activating The Atr-Cdc25c-Cdk1 Pathway., Peng Xu, Zhe Zhou, Min Xiong, Wei Zou, Xuefeng Deng, Safder S. Ganaie, Steve Kleiboeker, Jianxin Peng, Kaiyu Liu, Shengqi Wang, Shui Qing Ye, Jianming Qiu

Manuscripts, Articles, Book Chapters and Other Papers

Human parvovirus B19 (B19V) infection of primary human erythroid progenitor cells (EPCs) arrests infected cells at both late S-phase and G2-phase, which contain 4N DNA. B19V infection induces a DNA damage response (DDR) that facilitates viral DNA replication but is dispensable for cell cycle arrest at G2-phase; however, a putative C-terminal transactivation domain (TAD2) within NS1 is responsible for G2-phase arrest. To fully understand the mechanism underlying B19V NS1-induced G2-phase arrest, we established two doxycycline-inducible B19V-permissive UT7/Epo-S1 cell lines that express NS1 or NS1mTAD2, and examined the function of the TAD2 domain during G2-phase arrest. The results confirm that the …

Manuscripts, Articles, Book Chapters and Other Papers

Background: Outpatient parenteral antimicrobial therapy (OPAT) is overused in cases where highly bioavailable oral alternatives would be equally effective. However, the scope of OPAT use for children nationwide is poorly understood. Our objective was to characterize OPAT use and clinical outcomes for a large population of pediatric Medicaid enrollees treated with OPAT.

Methods: We analyzed the Truven MarketScan Medicaid claims database between 2009 and 2012. An OPAT episode was identified by capturing children with claims data indicating home infusion therapy for an intravenous antimicrobial. We characterized OPAT use by describing patient demographics, diagnoses, and antimicrobials prescribed. We categorized an antimicrobial …

Sequential Displacement Of Type Vi Secretion System Effector Genes Leads To Evolution Of Diverse Immunity Gene Arrays In Vibrio Cholerae, Paul C. Kirchberger, Daniel Unterweger, Daniele Provenzano, Stefan Pukatzki, Yan Boucher

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Type VI secretion systems (T6SS) enable bacteria to engage neighboring cells in contact-dependent competition. In Vibrio cholerae, three chromosomal clusters each encode a pair of effector and immunity genes downstream of those encoding the T6SS structural machinery for effector delivery. Different combinations of effector-immunity proteins lead to competition between strains of V. cholerae, which are thought to be protected only from the toxicity of their own effectors. Screening of all publically available V. cholerae genomes showed that numerous strains possess long arrays of orphan immunity genes encoded in the 3' region of their T6SS clusters. Phylogenetic analysis reveals that these …

“Looking Over The Backyard Fence”: Householders And Mosquito Control, Samir Mainali, Ram Sharan Lamichhane, Kim Clark, Shelley Beatty, Maria Fatouros, Peter Neville, Jacques Oosthuizen

Research outputs 2014 to 2021

Background:

Vector-borne diseases are a significant public health problem in Western Australia. Mosquitoes are responsible for the transmission of a number of pathogens and may pose a serious nuisance problem. Prevention efforts in the State are multi-faceted and include physical, chemical, and cultural control methods for restricting mosquito breeding. This is less complex where breeding areas are located within public open spaces. In Australia’s developed urban areas, breeding sites are, however, frequently located within private residential landholdings, where the scope of public health officials to act is constrained by law and practicality. Consequently, mosquito prevention in these locations is …

Effects Of Delayed Nsaid Administration After Experimental Eccentric Contraction Injury – A Cellular And Proteomics Study, Laura Bond

Biology Faculty Publications and Presentations

Background

Acute muscle injuries are exceedingly common and non-steroidal anti-inflammatory drugs (NSAIDs) are widely consumed to reduce the associated inflammation, swelling and pain that peak 1–2 days post-injury. While prophylactic use or early administration of NSAIDs has been shown to delay muscle regeneration and contribute to loss of muscle strength after healing, little is known about the effects of delayed NSAID use. Further, NSAID use following non-penetrating injury has been associated with increased risk and severity of infection, including that due to group A streptococcus, though the mechanisms remain to be elucidated. The present study investigated the effects of delayed …

The Role Of Quorum Sensing In Biofilm Formation Of Foodborne Micro-Organism, Zhang Guoli, Ao Xiaolin, Liu Shuliang

Food and Machinery

The biofilm is a multicellular group structure formed by numerous gathered microorganism which adheres on the surfaces. This phenomenon is widespread in a variety of foodborne micro-organism, and it is important for food processing and security. Quorum sensing (QS) has been proven to be an important factor in the formation of biofilm. In this review, the regulation function of QS in the biofilm formation of several kinds of foodborne bacteria and fungi was discussed, and this would provide reference to biofilm control and utilization in food processing.

Data-Driven Identification Of Potential Zika Virus Vectors, Michelle V. Evans, Tad A. Dallas, Barbara A. Han, Courtney C. Murdock, John M. Drake

Faculty Publications

© Evans et al. Zika is an emerging virus whose rapid spread is of great public health concern. Knowledge about transmission remains incomplete, especially concerning potential transmission in geographic areas in which it has not yet been introduced. To identify unknown vectors of Zika, we developed a data-driven model linking vector species and the Zika virus via vector-virus trait combinations that confer a propensity toward associations in an ecological network connecting flaviviruses and their mosquito vectors. Our model predicts that thirty-five species may be able to transmit the virus, seven of which are found in the continental United States, including …

College of Science & Mathematics Departmental Research

Antiviral defenses are inappropriately activated in systemic lupus erythematosus (SLE) and association between SLE and the antiviral helicase gene, IFIH1, is well established. We sought to extend the previously reported association of pathogenic soluble mediators and autoantibodies with mouse Mda5 to its human ortholog, IFIH1. To better understand the role this gene plays in human lupus, we assessed association of IFIH1 variants with soluble mediators and autoantibodies in 357 European-American SLE patients, first-degree relatives, and unrelated, unaffected healthy controls. Association between each of 135 genotyped SNPs in IFIH1 and four lupus-associated plasma mediators, IL-6, TNF-α, IFN-β, and IP-10, …

Boosting Of Hiv Envelope Cd4 Binding Site Antibodies With Long Variable Heavy Third Complementarity Determining Region In The Randomized Double Blind Rv305 Hiv-1 Vaccine Trial, David Easterhoff, M. Anthony Moody, Daniela Fera, Hao Cheng, Margaret Ackerman

Dartmouth Scholarship

The canary pox vector and gp120 vaccine (ALVAC-HIV and AIDSVAX B/E gp120) in the RV144 HIV-1 vaccine trial conferred an estimated 31% vaccine efficacy. Although the vaccine Env AE.A244 gp120 is antigenic for the unmutated common ancestor of V1V2 broadly neutralizing antibody (bnAbs), no plasma bnAb activity was induced. The RV305 (NCT01435135) HIV-1 clinical trial was a placebo-controlled randomized double-blinded study that assessed the safety and efficacy of vaccine boosting on B cell repertoires. HIV-1- uninfected RV144 vaccine recipients were reimmunized 6–8 years later with AIDSVAX B/E gp120 alone, ALVAC-HIV alone, or a combination of ALVAC-HIV and AIDSVAX B/E gp120 …
