The Ebola virus disease outbreak that began in Western Africa in December 2013 was unprecedented in both scope and spread, and the global response was slower and less coherent than was optimal given the scale and pace of the epidemic. Past experience with limited localized outbreaks, lack of licensed medical countermeasures, reluctance by first responders to direct scarce resources to clinical research, community resistance to outside interventions, and lack of local infrastructure were among the factors delaying clinical research during the outbreak...

Porcine epidemic diarrhea virus (PEDV) causes significant loss to the swine industry. The emergence of novel PEDV strains in recent years has decreased the effectiveness of PEDV vaccines. We have developed a live recombinant vaccine, a swinepox virus vector that expresses a truncated S protein (rSPV-St) from a recent PEDV strain, SQ2014, and evaluated its immunogenicity and effectiveness in a swine model. Vaccination of swine with rSPV-St elicited a robust antibody response specific for the homologous PEDV SQ2014...

We aimed to explore the temporal and spatial variations in mesothelioma incidence in Slovenia for the last 50 years and, among these, to evaluate the consequences of asbestos usage. The incidence data from the population-based Cancer Registry of Republic of Slovenia for the period 1961-2014 were analysed. The data of asbestos imported to Slovenia were used as a proxy for asbestos exposure in manufacturing areas. Log-linear joinpoint regression and age-period-cohort Poisson models were used in the time-trend analysis...

In specific forms of congenital heart defects and pulmonary hypertension, the right ventricle (RV) is exposed to systemic levels of pressure overload. The RV is prone to failure in these patients because of its vulnerability to chronic pressure overload. As patients with a systemic RV reach adulthood, an emerging epidemic of RV failure has become evident. Medical therapies proven for LV failure are ineffective in treating RV failure. Areas covered: In this review, the pathophysiology of the failing RV under pressure overload is discussed, with specific emphasis on the pivotal roles of angiogenesis and oxidative stress...

PURPOSE: Seasonal variations in asthma exacerbation (AE) are associated with respiratory virus outbreaks and the return of children to school after vacation. This study aims to elucidate the period, phase, and amplitude of seasonal cycles of AE in 5 different age groups with regard to rhino- and influenza virus epidemics in Korea. METHODS: The number of daily emergency department (ED) visits for AE in all age groups of Korea and the nationwide weekly incidence of rhino- and influenza virus, were obtained for 2008-2012...

The recent epidemic of Zika virus (ZIKV) in the Americas and its association with fetal and neurological complications has shown the need to develop a treatment. Repurposing of drugs that are already FDA approved or in clinical development may shorten drug development timelines in case of emerging viral diseases like ZIKV. Initial studies have shown conflicting results when testing sofosbuvir developed for treatment of infections with another Flaviviridae virus, hepatitis C virus. We hypothesized that the conflicting results could be explained by differences in intracellular processing of the compound...

People with chronic kidney disease (CKD) are at risk of severe outcomes, such as end-stage renal disease or cardiovascular disease, and CKD is a globally increasing health burden with a high personal and economic cost. Despite major progresses in prevention and therapeutics in last decades, research is still needed to reverse this epidemic trend. The regulation of water balance and the state of activation of the vasopressin system have emerged as factors tightly associated with kidney health, in the general population but also in specific conditions; among them, various stages of CKD, diabetes and autosomal dominant polycystic kidney disease (ADPKD)...

A novel GII.17 norovirus variant caused major gastroenteritis epidemics in China in 2014 -2016. To explore the host immune factors in selection of the emergence of this new variant, we characterized its antigenic relatedness with the GII.4 noroviruses that have dominated in China for decades. Through ELISA and histo-blood group antigen (HBGA) blocking assays using sera from GII.4 and the GII.17 variant-infected patients, respectively, we observed limited cross immune reactivity by the ELISA but little reactivity by the HBGA blocking assay between GII...

The first upsurge of enterovirus D68 (EV-D68), a causative agent of acute respiratory infections (ARIs), in Japan was reported in Osaka City in 2010. In this study, which began in 2010, we surveyed EV-D68 in children with ARIs and analyzed sequences of EV-D68 strains detected. Real-time PCR of 19 respiratory viruses or subtypes of viruses, including enterovirus, was performed on 2,215 specimens from ARI patients (<10 years of age) collected between November 2010 and December 2015 in Osaka City, Japan. EV-D68 was identified in 18 enterovirus-positive specimens (n = 4 in 2013, n = 1 in 2014, and n = 13 in 2015) by analysis of viral protein 1 (VP1) or VP4 sequences, followed by a BLAST search for similar sequences...

Due to the progressive aging of the population, Alzheimer's disease (AD) is becoming a healthcare burden of epidemic proportions for which there is currently no cure. Disappointing results from clinical trials performed in mild-moderate AD dementia combined with clear epidemiological evidence on AD risk factors are contributing to the development of primary prevention initiatives. In addition, the characterization of the long asymptomatic stage of AD is allowing the development of intervention studies and secondary prevention programmes on asymptomatic at-risk individuals, before substantial irreversible neuronal dysfunction and loss have occurred, an approach that emerges as highly relevant...

Successive global health crises - from HIV and AIDS to SARS and H5N1 to Ebola - highlight one of the most pressing challenges to global health security: the GAP - the governance accountability problem. Introduced in 2014 in the book entitled, HIV/AIDS and the South African state: The responsibility to respond, this article takes up Alan Whiteside's challenges, in a book review in these pages, to offer a more comprehensive analysis of the GAP. The GAP [Šehović, A. B. (2014). HIV/AIDS and the South African state: The responsibility to respond...

To date, a major attention was justly given to the global lineages of Mycobacterium tuberculosis. Here, we demonstrated an importance of the minor ones, on an example of intriguing and underestimated NEW-1 family that belongs to Euro-American lineage (lineage 4). Analysis of the global WGS/NGS datasets (5715 strains) identified 2235 strains of Lineage 4 and 66 strains of sublineage L4.5. This latter is marked with RD122 genomic deletion and includes NEW-1 family. Phylogenomic analysis confirmed a separate position of the NEW-1 family that we tentatively designate L4...

Hand, foot and mouth disease (HFMD) and herpangina (HA) are common childhood diseases mostly associated with human enteroviruses (EV). Although usually benign illnesses, neurological complications may be observed during large epidemics when enterovirus A71 (EV-A71) is involved, as observed in the Asia Pacific Region and in China since the late 1990s. The occurrence of these complications warrants reinforcing the surveillance of the emergence of EV-A71 infections in France and Europe. Monitoring EV infections associated with HFMD can be considered as an effective tool to detect an upsurge of EV-A71 infections in a timely manner...

Recent high-profile activations of the US Centers for Disease Control and Prevention (CDC) Emergency Operations Center (EOC) include responses to the West African Ebola and Zika virus epidemics. Within the EOC, emergency responses are organized according to the Incident Management System, which provides a standardized structure and chain of command, regardless of whether the EOC activation occurs in response to an outbreak, natural disaster, or other type of public health emergency. By embedding key scientific roles, such as the associate director for science, and functions within a Scientific Response Section, the current CDC emergency response structure ensures that both urgent and important science issues receive needed attention...

Measles is a highly contagious viral disease. Transmission occurs from person to person through direct contact or by aerosolization of pharyngeal secretions. In the area of Verviers (Belgium), we were confronted to a group of patients with measles, a public health event with local concentration. In our hospital institution, our case index dates back to the beginning of February 2017 and the follow-up of the cases indicates an upward trajectory. Sorting measures and isolations of potential patients, extensive screening and vaccinations were undertaken and coordinated from an internal management unit...

While medical ethics has a long history, and research ethics guidance emerged more formally in the 1960s and 1970s, frameworks for public health ethics began to appear in the 1990s. The author's thinking about public health ethics evolved from consideration of some of the ethics and policy questions surfacing regularly in the HIV/AIDS epidemic. This essay discusses some of the shared commitments of public health and ethics, as well as how one might apply an ethics lens to public health programs, both generally and in the contexts of public health preparedness and obesity prevention...

Latex allergy emerged as an epidemic of anaphylaxis, occupational asthma, and clinical dilemmas in the 1980s. A systematic recognition, investigation, discovery, epidemiology, and prevention strategy followed. International attention and collaborations of investigators, government agencies, manufacturing, and health policy resulted in near elimination of a global epidemic. This article summarizes nearly 4 decades of work in control of this epidemic and focuses attention on future problems that still require resolution...

The Zika virus has emerged as a global public health concern. Its rapid geographic expansion is attributed to the success of Aedes mosquito vectors, but local epidemiological drivers are still poorly understood. Feira de Santana played a pivotal role in the Chikungunya epidemic in Brazil and was one of the first urban centres to report Zika infections. Using a climate-driven transmission model and notified Zika case data, we show that a low observation rate and high vectorial capacity translated into a significant attack rate during the 2015 outbreak, with a subsequent decline in 2016 and fade-out in 2017 due to herd-immunity...

BACKGROUND: Although the United States is in the midst of a narcotic epidemic, risk factors for use and the impact of perioperative narcotic use on total knee arthroplasty (TKA) outcomes is ill-defined. METHODS: A national database was queried for patients who underwent primary TKA from 2007 to 2015. Patients taking narcotics in the preoperative, and for a prolonged period of time postoperatively, were identified. The risk factors for prolonged narcotic use were analyzed with a regression analysis, in addition to evaluating preoperative and prolonged postoperative use as independent risk factors for short-term and long-term complications...
