Cancer In Youth Living With Hiv (Ylwhiv): A Narrative Review Of The Access To Oncological Services Among Ylwhiv And The Role Of Economic Strengthening In Child Health, Ruth G N Katumba, Ozge Sensoy Bahar, Kimberly J Johnson, Fred M Ssewamala

Open Access Publications

Youth Living with HIV/AIDS (YLWHIV) have a higher risk of developing immunodeficiency related illnesses including certain cancers than their general population counterparts of the same age. This narrative review of current available literature describes factors associated with pediatric access to oncological services, and the role economic strengthening could play in improving health outcomes for this vulnerable population. Findings suggest that both HIV-infected and -uninfected children living in low and middle-income countries struggle with access and adherence to cancer treatment and care. Cost of treatment is a major barrier to access and adherence. Asset-building savings programs may increase financial security and …

A Single-Nucleotide Polymorphism In A Plasmodium Berghei Apiap2 Transcription Factor Alters The Development Of Host Immunity, Munir Akkaya, Patrick W Sheehan, Et Al

Open Access Publications

The acquisition of malaria immunity is both remarkably slow and unpredictable. At present, we know little about the malaria parasite genes that influence the host's ability to mount a protective immune response. Here, we show that a single-nucleotide polymorphism (SNP) resulting in a single amino acid change (S to F) in an ApiAP2 transcription factor in the rodent malaria parasite

When Sting Meets Viruses: Sensing, Trafficking And Response, Zhaohe Li, Siqi Cai, Yutong Sun, Li Li, Siyuan Ding, Xin Wang

Open Access Publications

To effectively defend against microbial pathogens, the host cells mount antiviral innate immune responses by producing interferons (IFNs), and hundreds of IFN-stimulated genes (ISGs). Upon recognition of cytoplasmic viral or bacterial DNAs and abnormal endogenous DNAs, the DNA sensor cGAS synthesizes 2',3'-cGAMP that induces STING (stimulator of interferon genes) undergoing conformational changes, cellular trafficking, and the activation of downstream factors. Therefore, STING plays a pivotal role in preventing microbial pathogen infection by sensing DNAs during pathogen invasion. This review is dedicated to the recent advances in the dynamic regulations of STING activation, intracellular trafficking, and post-translational modifications (PTMs) by the …

Open Access Publications

IgE sensitization to cockroach allergens is associated with development of allergic diseases, such as asthma. To understand the relevance of different cockroach allergens for diagnosis and immunotherapy, a comprehensive analysis of IgE antibody levels and T cell reactivity to an expanded set of cockroach allergens and their relationship to disease was performed in a cohort of USA cockroach sensitized patients. IgE antibody levels to recombinant chitinase and hemocyanin were measured for 23 subjects by custom-made ImmunoCAPs and compared with IgE levels to eight cockroach allergens we previously reported for the same cohort.

Context Is Key: Delineating The Unique Functions Of Ifnα And Ifnβ In Disease, Lindsey E Fox, Marissa C Locke, Deborah J Lenschow

Open Access Publications

Type I interferons (IFNs) are critical effector cytokines of the immune system and were originally known for their important role in protecting against viral infections; however, they have more recently been shown to play protective or detrimental roles in many disease states. Type I IFNs consist of IFNα, IFNβ, IFNϵ, IFNκ, IFNω, and a few others, and they all signal through a shared receptor to exert a wide range of biological activities, including antiviral, antiproliferative, proapoptotic, and immunomodulatory effects. Though the individual type I IFN subtypes possess overlapping functions, there is growing appreciation that they also have unique properties. In …

The Complex Interactions Between Rotavirus And The Gut Microbiota, Andrew Hyoungjin Kim, Michael P Hogarty, Vanessa C Harris, Megan T Baldridge

Open Access Publications

Human rotavirus (HRV) is the leading worldwide cause of acute diarrhea-related death in children under the age of five. RV infects the small intestine, an important site of colonization by the microbiota, and studies over the past decade have begun to reveal a complex set of interactions between RV and the gut microbiota. RV infection can temporarily alter the composition of the gut microbiota and probiotic administration alleviates some symptoms of infection

Prevalence Of Cryptococcal Antigen And Outcomes In People With Human Immunodeficiency Virus In Honduras: A Cohort Study, Julio C. Zuniga-Moya, Jane A. O'Halloran, Andrej Spec, Et Al

Open Access Publications

Background: Cryptococcal meningitis is a major cause of death among people with human immunodeficiency virus (PWH). Cryptococcal antigen (CrAg) testing of asymptomatic patients is an important public health measure to reduce mortality in high-incidence areas. However, limited data exist on CrAg prevalence in Central America.

Methods: We conducted a prospective cohort study at the 2 largest human immunodeficiency virus (HIV) clinics and hospitals in Honduras. Cryptococcal antigen in serum and cerebrospinal fluid was performed in individuals with HIV who had CD4 ≤100 cells/mm

Results: A total of 220 PWH were tested for CrAg, 12.7% (n = 28) of which tested …

Monocyte Distribution Width Enhances Early Sepsis Detection In The Emergency Department Beyond Sirs And Qsofa, Elliott D Crouser, Joseph E Parrillo, Greg S Martin, David T Huang, Pierre Hausfater, Ilya Grigorov, Diana Careaga, Tiffany Osborn, Mohamad Hasan, Liliana Tejidor

Open Access Publications

BACKGROUND: The initial presentation of sepsis in the emergency department (ED) is difficult to distinguish from other acute illnesses based upon similar clinical presentations. A new blood parameter, a measurement of increased monocyte volume distribution width (MDW), may be used in combination with other clinical parameters to improve early sepsis detection. We sought to determine if MDW, when combined with other available clinical parameters at the time of ED presentation, improves the early detection of sepsis.

METHODS: A retrospective analysis of prospectively collected clinical data available during the initial ED encounter of 2158 adult patients who were enrolled from emergency …

2020-Current year OA Pubs

Background: Disease-modifying therapies (DMTs) for multiple sclerosis (MS) are approved for the treatment of disease activity and are effective in reducing relapses and new magnetic resonance imaging (MRI) lesions. However, disease activity generally subsides with time, and age-dependent changes in DMT efficacy are not well-established. We aimed to investigate whether age impacts the efficacy of DMTs in treating disease activity in patients with relapsing-remitting MS (RRMS).

Methods: DMT efficacy related to age was assessed through a meta-analysis of clinical trials that evaluated the efficacy of DMTs in RRMS patients as measured by reductions in the annualized relapse rate (ARR), new …

Roles Of Reconstituted High-Density Lipoprotein Nanoparticles In Cardiovascular Disease: A New Paradigm For Drug Discovery, Jiansheng Huang, Dongdong Wang, Li-Hao Huang, Hui Huang

Open Access Publications

Epidemiological results revealed that there is an inverse correlation between high-density lipoprotein (HDL) cholesterol levels and risks of atherosclerotic cardiovascular disease (ASCVD). Mounting evidence supports that HDLs are atheroprotective, therefore, many therapeutic approaches have been developed to increase HDL cholesterol (HDL-C) levels. Nevertheless, HDL-raising therapies, such as cholesteryl ester transfer protein (CETP) inhibitors, failed to ameliorate cardiovascular outcomes in clinical trials, thereby casting doubt on the treatment of cardiovascular disease (CVD) by increasing HDL-C levels. Therefore, HDL-targeted interventional studies were shifted to increasing the number of HDL particles capable of promoting ATP-binding cassette transporter A1 (ABCA1)-mediated cholesterol efflux. One such …

Genetic Loci Associated With Prevalent And Incident Myocardial Infarction And Coronary Heart Disease In The Cohorts For Heart And Aging Research In Genomic Epidemiology (Charge) Consortium, Julie Hahn, Mary F. Feitosa, Et Al.

Open Access Publications

BACKGROUND: Genome-wide association studies have identified multiple genomic loci associated with coronary artery disease, but most are common variants in non-coding regions that provide limited information on causal genes and etiology of the disease. To overcome the limited scope that common variants provide, we focused our investigation on low-frequency and rare sequence variations primarily residing in coding regions of the genome.

METHODS AND RESULTS: Using samples of individuals of European ancestry from ten cohorts within the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium, both cross-sectional and prospective analyses were conducted to examine associations between genetic variants …
