“Looking Over The Backyard Fence”: Householders And Mosquito Control, Samir Mainali, Ram Sharan Lamichhane, Kim Clark, Shelley Beatty, Maria Fatouros, Peter Neville, Jacques Oosthuizen Mar 2017

“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 …

INTRODUCTION:

Successful population-level antiretroviral therapy (ART) adherence will be necessary to realize both the clinical and prevention benefits of antiretroviral scale-up and, ultimately, the end of AIDS. Although many people living with HIV are adhering well, others struggle and most are likely to experience challenges in adherence that may threaten virologic suppression at some point during lifelong therapy. Despite the importance of ART adherence, supportive interventions have generally not been implemented at scale. The objective of this review is to summarize the recommendations of clinical, research, and public health experts for scalable ART adherence interventions in resource-limited settings.

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 Mar 2017

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 …

Outpatient Parenteral Antimicrobial Therapy In Pediatric Medicaid Enrollees., Jennifer Goldman, Troy Richardson, Jason G. Newland, Brian R. Lee, Jeffrey S. Gerber, Matt Hall, Matthew Kronman, Adam L. Hersh

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 …

All Peer-Reviewed Publications

Background: Rift Valley fever (RVF) is a mosquito-borne viral zoonosis of ruminants and humans that causes outbreaks in Africa and the Arabian Peninsula with significant public health and economic consequences. Humans become infected through mosquito bites and contact with infected livestock. The virus is maintained between outbreaks through vertically infected eggs of the primary vectors of Aedes species which emerge following rains with extensive flooding. Infected female mosquitoes initiate transmission among nearby animals, which amplifies virus, thereby infecting more mosquitoes and moving the virus beyond the initial point of emergence. With each successive outbreak, RVF has been found to expand …

All Peer-Reviewed Publications

Rift Valley fever (RVF) is a viral mosquito-borne disease with the potential for global expansion, causes hemorrhagic fever, and has a high case fatality rate in young animals and in humans. Using a cross-sectional community-based study design, we investigated the knowledge, attitudes and practices of people living in small village in Sudan with respect to RVF outbreaks. A special One Health questionnaire was developed to compile data from 235 heads of household concerning their knowledge, attitudes, and practices with regard to controlling RVF. Although the 2007 RVF outbreak in Sudan had negatively affected the participants’ food availability and livestock income, …

Recent reports suggest that Opisthorchis viverrini serves as a reservoir of Helicobacter and implicate Helicobacter in pathogenesis of opisthorchiasis-associated cholangiocarcinoma (CCA). Here, 553 age-sex matched cases and controls, 293 and 260 positive and negative for liver fluke O. viverrini eggs, of residents in Northeastern Thailand were investigated for associations among infection with liver fluke, Helicobacter and hepatobiliary fibrosis. The prevalence of H. pylori infection was higher in O. viverrini-infected than uninfected participants. H. pylori bacterial load correlated positively with intensity of O. viverrini infection, and participants with opisthorchiasis exhibited higher frequency of virulent cagA-positive H. pylori than those free of …

A new generation of vaccines for the neglected tropical diseases (NTDs) have now advanced into clinical development, with the Na-GST-1/Alhydrogel Hookworm Vaccine already being tested in Phase 1 studies in healthy adults. The current manuscript focuses on the often overlooked critical aspects of NTD vaccine product development, more specifically, vaccine stability testing programs. A key measure of vaccine stability testing is "relative potency" or the immunogenicity of the vaccine during storage. As with most NTD vaccines, the Na-GST-1/Alhydrogel Hookworm Vaccine was not developed by attenuation or inactivation of the pathogen (Necator americanus), so conventional methods for measuring relative potency are …


Potent Single-Domain Antibodies That Arrest Respiratory Syncytial Virus Fusion Protein In Its Prefusion State, Iebe Rossey, Morgan Gilman, Stephanie Kabeche, Koen Sedeyn, Daniel Wrapp Feb 2017

Potent Single-Domain Antibodies That Arrest Respiratory Syncytial Virus Fusion Protein In Its Prefusion State, Iebe Rossey, Morgan Gilman, Stephanie Kabeche, Koen Sedeyn, Daniel Wrapp

Dartmouth Scholarship

Human respiratory syncytial virus (RSV) is the main cause of lower respiratory tract infections in young children. The RSV fusion protein (F) is highly conserved and is the only viral membrane protein that is essential for infection. The prefusion conformation of RSV F is considered the most relevant target for antiviral strategies because it is the fusion-competent form of the protein and the primary target of neutralizing activity present in human serum. Here, we describe two llama-derived single-domain antibodies (VHHs) that have potent RSV-neutralizing activity and bind selectively to prefusion RSV F with picomolar affinity. Crystal structures of these VHHs …


The Battle Against Malaria: A Teachable Moment, Randy K. Schwartz Feb 2017

The Battle Against Malaria: A Teachable Moment, Randy K. Schwartz

Journal of Humanistic Mathematics

Malaria has been humanity’s worst public health problem throughout recorded history. Mathematical methods are needed to understand which factors are relevant to the disease and to develop counter-measures against it. This article and the accompanying exercises provide examples of those methods for use in lower- or upper-level courses dealing with probability, statistics, or population modeling. These can be used to illustrate such concepts as correlation, causation, conditional probability, and independence. The article explains how the apparent link between sickle cell trait and resistance to malaria was first verified in Uganda using the chi-squared probability distribution. It goes on to explain …

Cancer may be induced by many environmental and physiological conditions. Infections with viruses, bacteria and parasites have been recognized for years to be associated with human carcinogenicity. Here we review current concepts of carcinogenicity and its associations with parasitic infections. The helminth diseases schistosomiasis, opisthorchiasis, and clonorchiasis are highly carcinogenic while the protozoan Trypanosoma cruzi, the causing agent of Chagas disease, has a dual role in the development of cancer, including both carcinogenic and anticancer properties. Although malaria per se does not appear to be causative in carcinogenesis, it is strongly associated with the occurrence of endemic Burkitt lymphoma in …

Infection Control In Labor And Delivery Room, Learning From The Small Hospital Based Project, Savera Aziz Ali, Sumera Aziz Ali

School of Nursing & Midwifery

Background: It has been estimated that around 36% of the neonatal deaths occur due to infection in the lower and middle income countries. Infection control is a more substantial area of concern, particularly in Labor and delivery room. Multiple factors can cause infection in the labor room, therefore it is important to assess various factors of maternal and neonatal infection. Hence we explored multiple factors through this project and developed the action plan to address those factors effectively.
Methods: During our Leadership and Management course, we conducted a project in Labor room pertaining to a prevalent issue. The whole process …


Clinical Risk Factors For Infective Endocarditis In Staphylococcus Aureus Bacteremia, Vincent Bryan D Salvador, Bikash Chapagain, Astha Joshi, Debra J Brennessel Feb 2017

Clinical Risk Factors For Infective Endocarditis In Staphylococcus Aureus Bacteremia, Vincent Bryan D Salvador, Bikash Chapagain, Astha Joshi, Debra J Brennessel

The Texas Heart Institute Journal

Crucial to the management of staphylococcal bacteremia is an accurate evaluation of associated endocarditis, which has both therapeutic and prognostic implications. Because the clinical presentation of endocarditis can be nonspecific, the judicious use of echocardiography is important in distinguishing patients at high risk of developing endocarditis. In the presence of high-risk clinical features, an early transesophageal echocardiogram is warranted without prior transthoracic echocardiography.

The purpose of this study was to investigate the clinical risk factors for staphylococcal infective endocarditis that might warrant earlier transesophageal echocardiography and to describe the incidence of endocarditis in cases of methicillin-resistant and methicillin-sensitive Staphylococcus aureus …

Kelley, Rafael Fernandez-Botran, William A. Mattingly, Forest W. Arnold, Stephen P. Furmanek, Marcos I. Restrepo, James D. Chalmers, Paula Peyrani, Rodrigo Cavallazzi, Jose Bordon, Stefano Aliberti, Julio A. Ramirez

The University of Louisville Journal of Respiratory Infections

Purpose: Patients with severe community-acquired pneumonia (CAP) are believed to have an exaggerated inflammatory response to bacterial infection. Therapies aiming to modulate the inflammatory response have been largely unsuccessful, perhaps reflecting that CAP is a heterogeneous disorder that cannot be modulated by a single anti-inflammatory approach. We hypothesize that the host inflammatory response to pneumonia may be characterized by distinct cytokine patterns, which can be harnessed for personalized therapies.

Methods: Here, we use hierarchical cluster analysis of cytokines to examine if patterns of inflammatory response in 13 hospitalized patients with CAP can be defined. This was a secondary data analysis …

Herpes Simplex Virus Type Ii In A Patient Having Periodic Lateralized Epileptiform Discharges, Justin Chuang, Sona K. Shah

Marshall Journal of Medicine

Herpes Simplex Encephalitis has been found to be one of the most common causes of fatal viral encephalitis (1). The mortality rate in untreated patients has been found to be as high as 70%, thus, correct management and early diagnosis are important for good prognoses and crucial for predicting outcomes. (1,2) In patients with Herpes Simplex Virus (HSV), specific findings such as the Periodic lateralized epileptic form discharges (PLEDs) are considered a specific finding on electroencephalogram (EEG). PLEDs are usually seen in the context of destructive structural lesions involving the cortex. Other causes may include acute ischemic stroke and, less …

A Comparison Of The Quality Of Informed Consent For Clinical Trials Of An Experimental Hookworm Vaccine Conducted In Developed And Developing Countries., David J. Diemert, Lucas Lobato, Ashley Styczynski, Maria Zumer, Amanda Soares, Maria Flávia Gazzinelli

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Informed consent is one of the principal ethical requirements of conducting clinical research, regardless of the study setting. Breaches in the quality of the informed consent process are frequently described in reference to clinical trials conducted in developing countries, due to low levels of formal education, a lack of familiarity with biomedical research, and limited access to health services in these countries. However, few studies have directly compared the quality of the informed consent process in developed and developing countries using the same tool and in similar clinical trials. This study was conducted to compare the quality of the informed …

Microbiology, Immunology, and Tropical Medicine Faculty Publications

BACKGROUND: Despite important progress in the field of innate immunity, our understanding of host immune responses to parasitic nematode infections lags behind that of responses to microbes. A limiting factor has been the obligate requirement for a vertebrate host which has hindered investigation of the parasitic nematode infective process. The nematode parasite Heterorhabditis bacteriophora offers great potential as a model to genetically dissect the process of infection. With its mutualistic Photorhabdus luminescens bacteria, H. bacteriophora invades multiple species of insects, which it kills and exploits as a food source for the development of several nematode generations. The ability to culture …

Praziquantel (PZQ) is an effective chemotherapy for schistosomiasis mansoni and a mainstay for its control and potential elimination. However, it does not prevent against reinfection, which can occur rapidly in areas with active transmission. A guide to ranking the risk factors for Schistosoma mansoni reinfection would greatly contribute to prioritizing resources and focusing prevention and control measures to prevent rapid reinfection. The objective of the current study was to explore the relationship among the socioeconomic, demographic, and epidemiological factors that can influence reinfection by S. mansoni one year after successful treatment with PZQ in school-aged children in Northeastern Minas …

Ancylostoma Ceylanicum Infective Third-Stage Larvae Are Activated By Co-Culture With Ht-29-Mtx Intestinal Epithelial Cells, Caitlin Feather, John M. Hawdon, John March

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Human hookworm larvae arrest development until they enter an appropriate host. This makes it difficult to access the larvae for studying larval development or host-parasite interactions. While there are in vivo and in vitro animal models of human hookworm infection, there is currently no human, in vitro model. While animal models have provided much insight into hookworm biology, there are limitations to how closely this can replicate human infection. Therefore, we have developed a human, in vitro model of the initial phase of hookworm infection using intestinal epithelial cell culture.

Results

Co-culture of the human hookworm Ancylostoma ceylanicum with …

In many developing countries, concerted action against common childhood infectious diseases has resulted in remarkable reduction in infant and under-five mortality. As a result, pediatric cardiovascular diseases are emerging as a major contributor to childhood morbidity and mortality. Pediatric cardiac surgery and cardiac catheterization interventions are available in only a few of Sub-Saharan African countries. In Uganda, open heart surgeries (OHSs) and interventional procedures for pediatric cardiovascular disease are only possible at the Uganda Heart Institute (UHI), having been started with the help of expatriate teams from the years 2007 and 2012, respectively. Thereafter, independent OHS and cardiac catheterization have …

African Americans have higher rates of asthma prevalence, morbidity, and mortality in comparison with other racial groups. We sought to characterize endotypes of childhood asthma severity in African American patients in an inner-city pediatric asthma population.
