Community Perception Of The Hiv Vaccine In Western Kenya: Acceptability, Potential Behavior Changes, And Views On Compulsory Vaccination, Deborah Keen

Independent Study Project (ISP) Collection

Human Immunodeficiency Virus (HIV) suppresses the immune system by attacking T cells, leading to the development of acquired immunodeficiency syndrome (AIDS). HIV affects over 30 million people around the world and 1.6 million people in Kenya. On August 18, 1987, the FDA sanctioned the first human testing of a candidate vaccine for HIV. Currently, multiple HIV vaccines—projected to be on the market in five to ten years—are being tested for efficacy and safety. The goal of this study was to explore opinions related to the HIV vaccine so that there is a guide for future policy development in Western Kenya. …

Characterization Of Different Molecular Markers For Identification Of Salmonella Enterica Serovar Typhi In Pakistani Population, Faizan Muttiullah, Fida Muhammad Khan, Fakhar-I- Abbas, Sabiha Shamim

Journal of Bioresource Management

Typhoid is caused by Salmonella enterica serovar Typhi that is usually diagnosed by using serologic and immuno-chromatographic techniques in developing counties including Pakistan, which is thought to be an unreliable diagnostic method. For accurate diagnosis we used molecular techniques to amplify 204 bp StyR-36 and 498 bp flagellin gene for the identification of Salmonella enterica serovar Typhi. This study was done on 58 individuals diagnosed positive of typhoid via serologic tests and 50 healthy individuals as a control group. Success rate of amplification for flagellin gene was 77.58% while that for StyR-36 gene was 68.97% showing that flagellin gene primer …

Introduction: Central line-associated bloodstream infections (CLABSI) are the most important cause of morbidity and mortality in critically ill patients. Evidence-based interventions when used in form of a bundle have proven to decrease CLABSI. Our unit has a high CLABSI rate (9/1000 central line days). Therefore, we intend to introduce evidence-based CLABSI prevention package in our practice to improve CLABSI rates in our NICU within limited resources.
Methods and Analysis: The study will be conducted using preanalysis and postanalysis design from January 2016 to December 2017. It is going to be conducted in three phases with phase I being the preimplimentation …

Prevalence Of Kaposi’S Sarcoma-Associated Herpesvirus In Uygur And Han Populations From The Urumqi And Kashgar Regions Of Xinjiang, China, Jun Zheng, Yang Yang, Meng Cui, Zhan-Jun Shu, Li-Li Han, Zhen-Qiu Liu, Charles Wood, Tiejun Zhang, Yan Zeng

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the infectious etiologic agent associated with Kaposi’s sarcoma (KS), primary effusion lymphoma, and multicentric Castleman disease. It has been shown that high KSHV prevalence and high incidence of both classic KS and AIDSassociated KS are found mostly among people of Uygur ethnicity in Xinjiang, while people of Han ethnicity in Xinjiang have a higher KSHV seroprevalence than those of other Han populations in mainland China. However, it is still unclear why there is such geographical and population variation in KSHV distribution in China. In this work, we focused on the populations in the Kashgar region …

Neurosyphilis Increases Human Immunodeficiency Virus (Hiv)-Associated Central Nervous System Inflammation But Does Not Explain Cognitive Impairment In Hiv-Infected Individuals With Syphilis., Emily L Ho, Clare L Maxwell, Shelia B Dunaway, Sharon K Sahi, Lauren C Tantalo, Sheila A Lukehart, Christina M Marra

Articles, Abstracts, and Reports

Background: Individuals infected with human immunodeficiency virus (HIV) who have previously had syphilis may have cognitive impairment. We tested the hypothesis that neurosyphilis causes cognitive impairment in HIV by amplifying HIV-related central nervous system (CNS) inflammation.

Methods: HIV-infected participants enrolled in a study of cerebrospinal fluid (CSF) abnormalities in syphilis underwent the mental alternation test (MAT), venipuncture, and lumbar puncture. CSF concentrations of chemokine (C-X-C motif) ligand 10 (CXCL10), chemokine (C-C motif) ligand 2 (CCL2), and neurofilament light (NFL) were determined by commercial assays. The proportion of peripheral blood mononuclear cells (PBMCs) and of CSF white blood cells (WBCs) that …

Data-independent acquisition mass spectrometry promises higher performance in terms of quantification and reproducibility compared to data-dependent acquisition mass spectrometry methods. To enable high-accuracy quantification of Staphylococcus aureus proteins, we have developed a global ion library for data-independent acquisition approaches employing high-resolution time of flight or Orbitrap instruments for this human pathogen. We applied this ion library resource to investigate the time-resolved adaptation of S. aureus to the intracellular niche in human bronchial epithelial cells and in a murine pneumonia model. In epithelial cells, abundance changes for more than 400 S. aureus proteins were quantified, revealing, e.g., the precise temporal regulation …

Persistence Of Macrocytosis After Discontinuation Of Zidovudine In Hiv-Infected Patients, Inski Yu, Richard N. Greenberg, Timothy N. Crawford, Alice C. Thornton, Thein Myint

Internal Medicine Faculty Publications

The duration of macrocytosis after stopping zidovudine (ZDV) is unknown. Among 104 HIV-infected patients treated with ZDV for more than 1 year, 84 patients had macrocytosis at ZDV discontinuation. The median mean corpuscular volume (MCV) was 114.6 fL (range 100-128 fL). Patients were divided into 2 groups: those who did (resolved macrocytosis, n = 36) and did not (persistent macrocytosis, n = 48) normalize MCV at 3 to 6 months after ZDV discontinuation. Alcohol use (P = .02), smoking (P = .03), and lower (but within normal range) folic acid levels (P = .05) were related to …

Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Due to the vast geographical distribution and significant economic losses generated, porcine reproductive and respiratory syndrome virus (PRRSV) can be considered the most important swine pathogen of contemporary times. Current control and eradication strategies against PRRSV have difficulty succeeding because of their complex nature and the absence of an effective vaccine. A major obstacle for PRRSV vaccine development is the broad heterogeneity of the virus, both at the genetic and antigenic level, its rapid evolution, and an incomplete knowledge of the immune responses responsible for clearing the virus from the host. Specifically, how known correlates of protection against PRRSV—neutralizing antibodies …

The information regarding HPV vaccination was gathered from the parents of 9- to 17-year-old daughters (choosing only 1 per household) in randomly selected households in the sample area.

Results: The highest prevalence of vaccine initiation and completion were detected in 2010 (20.9% and 9.7%, respectively). Over the study period, HPV vaccine initiation statistically significantly increased (2008, 14.9%; 2009, 20.7%; …

Relative Contribution Of Porcine Reproductive And Respiratory Syndrome Virus Open Reading Frames 2–4 To The Induction Of Protective Immunity, Katherine Kimpston-Burkgren, Ignacio Correas, Fernando A. Osorio, David Steffen, Asit K. Pattnaik, Ying Fang, Hiep L. X. Vu

Nebraska Center for Virology: Faculty Publications

The minor glycoproteins (GPs) of PRRSV, GP2, GP3, and GP4, form a heterotrimer that is required for viral infectivity, presumably due to its interaction with the key cellular receptor CD163. These 3 GPs are encoded by open reading frames (ORFs) 2a, 3, and 4 (herein referred to as ORFs 2–4), respectively. The goal of this study was to investigate the immunogenicity of the PRRSV-2 minor GPs. Through the use of reverse genetics, a chimeric virus (designated SDFL24) was constructed by replacing ORFs 2–4 of the PRRSV-1 strain SD01-08 with the corresponding genes of the PRRSV-2 strain FL12. While the parental …

Effects Of Acute Sepsis On Renal Structure And Sympathetic Innervation In Mice, Tuqa Alkhateeb

Electronic Theses and Dissertations

Sympathetic nerves are important for renal physiology and sepsis pathophysiology. A recent study showed sprouting of sympathetic nerves in spleen of septic mice. This study was done to test if renal sprouting of sympathetic nerves also happens and to investigate renal morphology in septic mice. Cecal ligation and puncture (CLP) was used to induce sepsis and kidneys were removed for evaluation. Bowman’s space was diminished with cortical bubble cells present suggestive of acute renal pathology, however, renal function was unchanged. Acute sepsis did not affect either renal sympathetic innervation or non-neuronal cholinergic cells. Mouse kidneys had more epinephrine (EPI) than …

One combined measles-mumps-rubella (MMR) vaccine without Human Serum Albumin (HSA) is currently licensed in the USA (M-M-R II; Merck, USA) and another has been developed (Priorix™ [MMR-RIT, GSK, Belgium]). In this follow-up study, children from USA or Puerto Rico, who had received one dose of M-M-R II or MMR-RIT at 12-15 months of age in the primary study (NCT00861744), were followed-up for 2 y post-vaccination. Anti-measles and anti-rubella antibodies were measured using Enzyme-Linked Immunosorbent Assay (ELISA), and anti-mumps antibodies using ELISA and plaque reduction neutralization (PRN) assays. Serious adverse events (SAEs) were recorded during the entire follow-up. The according-to-protocol (ATP) …

Mortality In Patients With Respiratory And Nonrespiratory Carbapenem Resistant-Multidrug Resistant Acinetobacter Infections, Nosheen Nasir, S Mahmood

Department of Medicine

Background: Mortality from carbapenem-multi-drug resistant Acinetobacter infections may vary according to site of infection. The objective of this study was to compare mortality in respiratory vs. non-respiratory infection with Carbapenem-Multi-drug Resistant Acinetobacter (C-MRAB).

Methods: We conducted a prospective cohort study to compare mortality rate in patients with respiratory vs. nonrespiratory infection (n=30 each).

Results: Results showed that mortality was 40% in the respiratory group compared to 23% in non-respiratory group; the difference was not statistically significant (p=0.165, RR=1.71, CI=0.73-3.75). There was a significantly higher prior admission rate in patients with respiratory infection (p=0.028). Logistic regression did not reveal any modifier …
