Pathogens often follow more than one transmission route during outbreaks-from needle sharing plus sexual transmission of HIV to small droplet aerosol plus fomite transmission of influenza. Thus, controlling an infectious disease outbreak often requires characterizing the risk associated with multiple mechanisms of transmission. For example, during the Ebola virus outbreak in West Africa, weighing the relative importance of funeral versus health care worker transmission was essential to stopping disease spread...

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging epidemic infectious disease caused by the SFTS bunyavirus (SFTSV) with an estimated high case-fatality rate of 12.7% to 32.6%. Currently, the disease has been reported in mainland China, Japan, Korea, and the United States. At present, there is no specific antiviral therapy for SFTSV infection. Considering the higher mortality rate and rapid clinical progress of SFTS, supporting the appropriate treatment in time to SFTS patients is critical. Therefore, it is very important for clinicians to predict these SFTS cases who are more likely to have a poor prognosis or even more likely to decease...

In response to Rhode Island's overdose epidemic, we developed a collaborative, statewide online "dashboard" to provide the public with timely overdose surveillance data. The Web site- www.PreventOverdoseRI.org (PORI)-offers user-friendly data visualizations, plain language education, and interactive resource maps. Development of the site has improved overdose data sharing and transparency in Rhode Island. Preliminary results suggest a successful site launch. Future research will evaluate the effectiveness of PORI in terms of informing strategic initiatives to reduce overdoses in affected communities...

After two years of discussions and delays surrounding his eventual departure, Alan Gregg, the 37-year-old associate director of the Rockefeller Foundation's Division of Medical Education (DME), set out from his Paris, France, office in late November 1927, destined for a 17-day trip to Moscow and Leningrad in the Soviet Union. His mission-the first time a Rockefeller officer had ever set foot on Soviet soil(1)-was to gather first-hand knowledge about the state of public health and medical education in Russia, as a precursor for offering training fellowships to Russian physicians...

The 2013-2016 Ebola epidemic in West Africa challenged traditional international mechanisms for public health team mobilisation to control outbreaks. Consequently, in February 2016, the European Union (EU) launched the European Medical Corps (EMC), a mechanism developed in collaboration with the World Health Organization (WHO) to rapidly deploy teams and equipment in response to public health emergencies inside and outside the EU. Public Health Teams (PHTs), a component of the EMC, consist of experts in communicable disease prevention and control from participating countries and the European Centre for Disease Prevention and Control (ECDC), to support affected countries and WHO in risk assessment and outbreak response...

The 'epidemic' diffusion of chronic kidney disease (CKD) needs the development of new therapeutic approaches to slow down the progression to end-stage renal disease. Endothelial Progenitor Cells (EPCs) are promising tools for the treatment of many human diseases as they promote the repair of damaged tissues. They were also suggested as therapy to repair renal tissue after an injury. Strategies using EPCs to induce a reparative process with functional restoring of a diseased kidney or to delay CKD are of two types: direct stem cells infusion or stimulating endogenous release of EPCs...

Influenza viruses cause severe upper respiratory illness in young children and the elderly during seasonal epidemics. Influenza viruses also have the potential to cause pandemics with significant loss of life in all age groups. Although vaccination is one of the most effective methods to protect against seasonal epidemics, seasonal vaccines afford lowered protection against emerging variant strains and no protection against novel strains. Moreover, the efficacy of influenza virus vaccines is considerably lower in the elderly population...

Viral hepatitis A (VHA) is the disease which has an ancient history. Reports of epidemic jaundice were described by Hippocrates in Greece during the 5th century B.C. Incidence of VHA in developed countries is dropping in last decades. What was once common disease is now very rare, usually emerging in local epidemies. With decreasing incidence of hepatitis A clinicians losing practical experiences with disease. Authors present possible diagnostic and therapeutic problems based on their experience with large epidemic of hepatitis A, which occurred in 2016-2017 in Brno area...

It is widely accepted that high calorie diets and a sedentary lifestyle sturdily influence the incidence and outcome of type 2 diabetes and obesity, which can occur simultaneously, a situation called diabesity. Tightly linked with metabolic and energy regulation, a close association between diabetes and Alzheimer's disease (AD) has been proposed. Among the common pathogenic mechanisms that underpin both conditions, insulin resistance, brain glucose hypometabolism, and metabolic dyshomeostasis appear to have a pivotal role...

BACKGROUND: Infection with Porcine Epidemic Diarrhea Virus (PEDV) causes vomiting, diarrhea, and dehydration in young pigs. The virus made its first appearance in the U.S. in 2013, where it caused substantial neonatal mortality and economic losses in the U.S. pork industry. Based on outbreak investigations, it is hypothesized that the virus could be transmitted through contaminated feed or contaminated feed surfaces. This potential risk created a demand for research on the inactivation kinetics of PEDV in different environments...

Despite having a relatively low prevalence in the Iranian general population, the burden of hepatitis C virus (HCV) infection is on the rise, and hepatitis C is predicted to be the most important leading cause of viral hepatitis-related mortality in the near future in Iran. The recent population-based epidemiological studies have revealed the predominant role of injecting drug use in increasing prevalence of HCV infection. Undoubtedly, new management paradigm is required to drive down the rising wave of hepatitis C in Iran...

We extend a technique of approximation of the long-term behavior of a supercritical stochastic epidemic model, using the WKB approximation and a Hamiltonian phase space, to the subcritical case. The limiting behavior of the model and approximation are qualitatively different in the subcritical case, requiring a novel analysis of the limiting behavior of the Hamiltonian system away from its deterministic subsystem. This yields a novel, general technique of approximation of the quasistationary distribution of stochastic epidemic and birth-death models and may lead to techniques for analysis of these models beyond the quasistationary distribution...

Cultivar resistance is an essential part of disease control programmes in many agricultural systems. The use of resistant cultivars applies a selection pressure on pathogen populations for the evolution of virulence, resulting in loss of disease control. Various techniques for the deployment of host resistance genes have been proposed to reduce the selection for virulence, but these are often difficult to apply in practice. We present a general technique to maintain the effectiveness of cultivar resistance...

OBJECTIVE: Recently several industrialized countries reported a stabilization or even a decrease in childhood overweight and obesity prevalence rates. In Germany, this trend started in 2004. The present study therefore aimed to evaluate whether this trend has continued or even leads in a clear direction. Design/Setting/Subjects BMI (>90th percentile (overweight), >97th percentile (obesity)) from the CrescNet database was analysed in 326 834 children and adolescents according to three age groups (4-7·99, 8-11·99 and 12-16 years), gender and between time points (2005-2015)...

Aedes aegypti is one of the species most favored by changes in the environment caused by urbanization. Its abundance increases rapidly in the face of such changes, increasing the risk of disease transmission. Previous studies have shown that mosquito species that have adapted to anthropogenic environmental changes benefit from urbanization and undergo population expansion. In light of this, we used microsatellite markers to explore how urbanization processes may be modulating Ae. aegypti populations collected from three areas with different levels of urbanization in the city of São Paulo, Brazil...

The interaction of neurotransmitters and genes that control the release of dopamine is the Brain Reward Cascade (BRC). Variations within the BRC, whether genetic or epigenetic, may predispose individuals to addictive behaviors and altered pain tolerance. This discussion authored by a group of concerned scientists and clinicians examines the Genetic Addiction Risk Score (GARS), the first test to accurately predict vulnerability to pain, addiction, and other compulsive behaviors, defined as Reward Deficiency Syndrome (RDS)...

In the history of human civilization, influenza is the second most catastrophic killer disease for mankind with plague ranking first in the medieval times. The 1918-1919 'Spanish flu' killed 20-50 million people worldwide. According to a report from WHO, there have been four pandemics, several epidemics and recurrent seasonal outbreaks of influenza in different parts of the world. The virus is a potential bioterrorism threat with biological 'Chernobyl-like disaster' that occurred in Soviet Russia in 1977. Here, the author reviews the biology of the surface exposed hemagglutinin of the influenza virus, a gene under constant positive selection pressure to evade host immunity and vaccination...

BACKGROUND: In response to the opioid epidemic and new guidelines, many patients on high-dose long term opioid therapy (LTOT) for chronic pain are getting tapered off opioids. As a result, a unique clinical challenge is emerging: while many on LTOT have poor pain control, functional decline, psychiatric instability, aberrancies and misuse, these issues may often worsen with opioid tapering. Currently, a clear explanation and practical guidance on how to manage this perplexing clinical scenario is lacking...
