Active surveillance

Nicole P Lindsey, J Erin Staples, Marc Fischer
Eastern equine encephalitis virus (EEEV) is a mosquito-borne alphavirus found in the eastern United States. Eastern equine encephalitis virus disease in humans is rare but can result in severe, often fatal, illness. This report summarizes the national EEEV surveillance data for 2003 through 2016, including human disease cases and nonhuman infections. Over the 14-year period, 633 counties from 33 states reported EEEV activity; 88% of those counties reported EEEV activity only in nonhuman species. A total of 121 human cases of EEEV disease were reported, with a median of eight cases reported annually...

Influenza A viruses (IAVs) are contagious pathogens responsible for severe respiratory infection in humans and animals worldwide. Upon detection of IAV infection, host immune system aims to defend against and clear the viral infection. Innate immune system is comprised of physical barriers (mucus and collectins), various phagocytic cells, group of cytokines, interferons (IFNs), and IFN-stimulated genes, which provide first line of defense against IAV infection. The adaptive immunity is mediated by B cells and T cells, characterized with antigen-specific memory cells, capturing and neutralizing the pathogen...

Since the approval of anti-CTLA4 therapy (ipilimumab) for late-stage melanoma in 2011, the development of anticancer immunotherapy agents has thrived. The success of many immune-checkpoint inhibitors has drastically changed the landscape of cancer treatment. For some types of cancer, monotherapy for targeting immune checkpoint pathways has proven more effective than traditional therapies, and combining immunotherapy with current treatment strategies may yield even better outcomes. Numerous preclinical studies have suggested that combining immunotherapy with radiotherapy could be a promising strategy for synergistic enhancement of treatment efficacy...

Introduction: Prediabetes is a condition in which individuals have blood glucose levels higher than normal but not high enough to be classified as diabetes mellitus. Inadequate moderate-intensity physical activity, amidst other risk factors, is a well-documented risk factor for prediabetes. Hospital administrative staff can be particularly vulnerable to prediabetes because of the greater number of hours spent in a sitting or sedentary position during administrative duties. The aim of this study was to find the prevalence of prediabetes and to determine its predictors among administrative staff of a tertiary health centre in southwestern Nigeria...

Human Tousled-like kinases (TLKs) are highly conserved serine/threonine protein kinases responsible for cell proliferation, DNA repair, and genome surveillance. Their possible involvement in cancer via efficient DNA repair mechanisms have made them clinically relevant molecular targets for anticancer therapy. Innovative approaches in chemical biology have played a key role in validating the importance of kinases as molecular targets. However, the detailed understanding of the protein structure and the mechanisms of protein-drug interaction through biochemical and biophysical techniques demands a method for the production of an active protein of exceptional stability and purity on a large scale...

Rezafungin (CD101) is a novel echinocandin antifungal agent with activity against Aspergillus and Candida species, including azole- and echinocandin-resistant isolates. The objective of these analyses was to conduct pharmacokinetic-pharmacodynamic (PK-PD) target attainment analyses to evaluate single and once-weekly rezafungin dosing to provide dose selection support for future clinical studies. Using a previously developed rezafungin population PK model, Monte Carlo simulations were conducted utilizing the following three IV rezafungin dosing regimens: (i) single 400-mg dose, (ii) 400 mg for Week 1 followed by 200 mg weekly for 5 weeks, and (iii) 400 mg weekly for 6 weeks...

This viewpoint paper argues that policy interventions can benefit from the continued use of social media analytics, which can serve as an important complement to traditional social science data collection and analysis. Efforts to improve well-being should provide an opportunity to explore these areas more deeply, and encourage the efforts of those conducting national and local data collection on health to incorporate more of these emerging data sources. Social media remains a relatively untapped source of information to catalyze policy action and social change...

BACKGROUND: Long-term survival with durable response remains possible in the area of targeted therapies. Discontinuation of sunitinib could improve quality of life and reduce treatment costs in metastatic renal cell carcinoma with long-term disease stabilization. We discuss a case of successful interruption of antiangiogenic therapy in a patient with persisting evidence of metastases. The discontinuation of antiangiogenic therapy seems to be an option, even in indolent oligo-metastatic renal cell carcinoma with long disease stabilization before sunitinib...

Drug reaction with eosinophilia and systemic symptoms (DRESS) is an infrequent, but severe, adverse drug-induced reaction which occurs due to massive T-cell stimulation resulting in cytotoxicity and eosinophil activation and recruitment. The incidence is 0.4 cases per 100, 0000 in the general population; the mortality rate is up to 10%. Therefore, we believe that recognizing this syndrome is of particular importance. The problem we notice is that DRESS is often seen and described in patients receiving rheumatologic or anticonvulsant drugs, but very rarely in psychiatric hospitals, where Clozapine is frequently used, and that is the importance of this paper...

BACKGROUND: Ductal carcinoma in situ (DCIS) can be a precursor to invasive breast cancer. Since the advent of screening mammography in the 1980's, the incidence of DCIS has increased dramatically. The value of screen detection and treatment of DCIS, however, is a matter of controversy, as it is unclear the extent to which detection and treatment of DCIS prevents invasive disease and reduces breast cancer mortality. The aim of this paper is to provide an overview of existing Cancer Intervention and Surveillance Modelling Network (CISNET) modeling approaches for the natural history of DCIS, and to compare these to other modeling approaches reported in the literature...

Expression from the HIV-1 LTR can be repressed in a small population of cells, which contributes to the latent reservoir. The factors mediating this repression have not been clearly elucidated. We have identified a network of nuclear RNA surveillance factors that act as effectors of HIV-1 silencing. RRP6, MTR4, ZCCHC8 and ZFC3H1 physically associate with the HIV-1 TAR region and repress transcriptional output and recruitment of RNAPII to the LTR. Knock-down of these factors in J-Lat cells increased the number of GFP-positive cells, with a concomitant increase in histone marks associated with transcriptional activation...

INTRODUCTION: Contemporary state-specific estimates of mortality caused by cigarette smoking are important for tobacco control advocacy and healthcare planning in the U.S., but are currently lacking. METHODS: The population-attributable fraction (i.e., proportion of deaths in the population caused by smoking), number of deaths, and number of years of potential life lost because of active cigarette smoking were estimated for each state based on state-specific smoking prevalence data from the 2014 Behavioral Risk Factor Surveillance System, recently updated relative risks of smoking, and numbers of deaths from smoking-attributable diseases...
