The 2014/15 influenza epidemic caused a work overload for healthcare facilities in France. The French national public health agency announced the start of the epidemic - based on indicators aggregated at the national level - too late for many hospitals to prepare. It was therefore decided to improve the influenza alert procedure through (i) the introduction of a pre-epidemic alert level to better anticipate future outbreaks, (ii) the regionalisation of surveillance so that healthcare structures can be informed of the arrival of epidemics in their region, (iii) the standardised use of data sources and statistical methods across regions...

Responsible for nearly 1.5 million deaths every year, the infectious disease tuberculosis remains one of the most serious challenges to global health. The emergence of multidrug-resistant tuberculosis and, more recently, extensively drug-resistant tuberculosis poses a significant threat in our effort to control this epidemic. New drugs are urgently needed to combat the growing threat of antimicrobial resistance. To achieve this goal, we screened approximately 500 species of medicinal plant methanol extracts and their solvent partitioned fractions for potential inhibitors of Mycobacterium tuberculosis growth...

Vibrio vulnificus is an environmental organism that causes septic human infections characterized by high morbidity and mortality. The annual incidence and global distribution of this pathogen are increasing as ocean waters warm. Clinical strains exhibit variations in the primary virulence toxin, suggesting a potential for the emergence of new strains with altered virulence properties. A clonal outbreak of tilapia-associated wound infections in Israel serves as a natural experiment for the sudden emergence of a new V...

Rational characterization of virulence and host-adaptive markers in the multifunctional influenza A virus NS1 protein is hindered by a lack of comprehensive knowledge about NS1-host protein-protein interfaces. Here, we surveyed the impact of amino-acid variation in NS1 at its structurally-defined binding site for host p85β, a regulator of phosphoinositide-3 kinase (PI3K) signaling. Structure-guided alanine-scanning of all viral residues at this interface defined 10 positions contributing to the interaction, with residues 89, 95, 98, 133, 145 and 162 being most important...

Zika virus (ZIKV) has caused significant outbreaks and epidemics in the Americas recently, raising global concern due to its ability to cause microcephaly and other neurological complications. A stable and efficient infectious clone of ZIKV is urgently needed. However, the instability and toxicity of flavivirus cDNA clones in E. coli hosts has hindered the development of ZIKV infectious clones. Herein, using a novel self-splicing ribozyme-based strategy, we have generated a stable infectious cDNA clone of a contemporary ZIKV strain imported from Venezuela to China in 2016...

Hepatitis E virus (HEV) causes an acute, self limiting hepatitis in normal individuals and leads to chronic disease in immunocompromised individuals. HEV infection in pregnant women results in a more severe outcome, with the mortality rate going upto 30%. Though the virus usually causes sporadic infection, epidemics have been reported in developing and resource starved countries. No specific anti-viral exists against HEV. A combination of interferon and ribavirin therapy has been used to control the disease with some success...

Antiretroviral therapy (ART) could curtail the HIV epidemic, but its impact is diminished by low uptake. We developed a peer navigation program to enhance engagement in HIV care, ART adherence, and behavioral prevention. In preparation for a randomized controlled trial, the program was piloted over four months at two primary health clinics in South Africa's North West Province. Newly diagnosed, HIV-positive clients met regularly with navigators to address barriers to care, adherence, and prevention. To assess program acceptability and feasibility and characterize the mechanisms of action, we surveyed 25 clients who completed navigation services and conducted interviews with 10 clients, four navigators, and five clinic providers...

A compelling body of evidence suggests that the worldwide obesity epidemic is underpinned by excessive sugar consumption, typified by the modern western diet. Furthermore, evidence is beginning to emerge of maladaptive changes in the mesolimbic reward pathway of the brain in relation to excess sugar consumption that highlights the importance of examining this neural circuitry in an attempt to understand and subsequently mitigate the associated morbidities with obesity. While the basolateral amygdala (BLA) has been shown to mediate the reinforcing properties of drugs of abuse, it has also been shown to play an important role in affective and motivated behaviours and has been shown to undergo maladaptive changes in response to drugs of abuse and stress...

BACKGROUND: The epidemiology of infective endocarditis (IE) depends on a number of host factors whose prevalence can vary globally. The usual patient population affected by IE is sicker and older, often with many comorbid conditions. The risk is growing in younger populations due to the emerging epidemic of intravenous (IV) drug use. We have performed a temporal trend analysis of various factors of IE in the rural counties covering a major part of central Upstate New York. METHODS: We performed a retrospective analysis of electronic medical records of patients who were admitted in a tertiary care hospital in rural Upstate New York and diagnosed with IE from January 1, 2011 to December 31, 2016...

The 2015 Brazilian Zika virus outbreak sparked a rapid response to control the spread of the virus. What was first understood to be a mild self-resolving infection is now linked to significant neurological defects in both neonates, and adults. The WHO declared the 2016 Zika epidemic a public health emergency and issued an unprecedented recommendation to women in affected regions to delay pregnancy until the risks surrounding Zika virus could be understood, or the epidemic contained. Since that time, considerable effort has been dedicated to understanding Zika transmission and pathogenesis to aid the development of drugs and vaccines...

OBJECTIVES: The US opioid medication epidemic has resulted in serious health consequences for patients. Formulary management tools adopted by payers, specifically prior authorization (PA) policies, may lower the rates of opioid medication abuse and overdose. We compared rates of opioid abuse and overdose among enrollees in plans that varied in their use of PA from "High PA" (ie, required PA for 17 to 74 opioids), with "Low PA" (ie, required PA for 1 opioid), and "No PA" policies for opioid medications...

BACKGROUND: Adolescents living with HIV are an emerging group in the global HIV/AIDS epidemic. Mental health in this population affects HIV care, treatment, consequential morbidity and secondary transmission. There is a paucity of research regarding these youth in South Africa (SA), partly because section 71 of the National Health Act of 2003 (NHA) requires parental or guardian's consent. OBJECTIVE: To explore legal and ethical issues related to conducting adolescent mental health research in SA...

Fatty liver diseases, which are commonly associated with high-fat/calorie diet, heavy alcohol consumption and/or other metabolic disorder causes, lead to serious medical concerns worldwide in recent years. It has been demonstrated that metabolic homeostasis disruption is most likely to be responsible for this global epidemic. Sirtuins are a group of conserved nicotinamide adenine dinucleotide (NAD(+)) dependent histone and/or protein deacetylases belonging to the silent information regulator 2 (Sir2) family...

The 2014-2016 epidemic of Ebola virus disease occurred in a region with a recent history of civil war, unstable health systems, and widespread poverty. Despite these contextual challenges, the national Ebola response in Liberia controlled transmission under strong leadership that was able to rapidly coordinate activities, to manage local and international players, and to adapt upon recognizing missteps. Such leadership has persisted to improve public health capacity in post-Ebola Liberia. This article highlights the progress made toward developing a resilient health security system with capacity to prevent, detect, and respond to disease threats before they reach epidemic level...
