BACKGROUND: The World Health Organization refers to stroke, the second most frequent cause of death in the world, in terms of pandemic. Present treatments are only effective within precise time windows. Only 10% of thrombolysis patients are eligible. Late assessment of the patient resulting from admission and lack of knowledge of the symptoms is the main explanation of lack of eligibility. METHODS: The aim is the measurement of the time of access to treatment facilities for stroke victims, using ambulances (firemen ambulances or EMS ambulances) and private car...

Background: The 1918 Spanish H1N1 influenza pandemic was the most severe recorded influenza pandemic with an estimated 20-50 million deaths worldwide. Even though it is known that influenza viruses can cause extra-respiratory tract complications-which are often severe or even fatal- the potential contribution of extra-respiratory tissues to the pathogenesis of 1918 H1N1 virus infection has not been studied comprehensively. Methods: Here, we performed a time course study in ferrets inoculated intranasally with 1918 H1N1 virus, with special emphasis on the involvement of extra-respiratory tissues...

West Africa occupies the third position with respect to the burden of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) globally, after Southern and East Africa. About 5 million adults and children are infected with the disease in the subregion, while HIV prevalence in the general population hovers around 2% and 5%. This paper attempts to investigate the impact of HIV/AIDS epidemic on human capital development in 11 West African countries over the period 1990 to 2011. The study used a dynamic panel data modeling approach, using first difference, difference generalized methods of moment, and system generalized methods of moment estimating techniques...

Bovine viral diarrhea virus (BVDV) infection is still a plague that causes important livestock pandemics. Despite the availability of vaccines against BVDV, and the implementation of massive eradication or control programs, this virus still constitutes a serious agronomic burden. Therefore, the alternative approach to combat Pestivirus infections, based on the development of antiviral agents that specifically inhibit the replication of these viruses, is of preeminent actuality and importance. Capitalizing from a long-standing experience in antiviral drug design and development, in this work we present and characterize a series of small molecules based on the 9-aminoacridine scaffold that exhibit potent anti-BVDV activity coupled with low cytotoxicity...

The factors that determine the pattern and rate of spread of influenza virus at a continental-scale are uncertain. Although recent work suggests that influenza epidemics in the United States exhibit a strong geographical correlation, the spatiotemporal dynamics of influenza in Australia, a country and continent of approximately similar size and climate complexity but with a far smaller population, are not known. Using a unique combination of large-scale laboratory-confirmed influenza surveillance comprising >450,000 entries and genomic sequence data we determined the local-level spatial diffusion of this important human pathogen nationwide in Australia...

Equine influenza, caused by the H3N8 subtype, is a highly contagious respiratory disease affecting equid populations worldwide and has led to serious epidemics and transboundary pandemics. This study describes the phylogenetic characterization and replication kinetics of recently-isolated H3N8 virus from a nasal swab obtained from a sporadic case of natural infection in an unvaccinated horse from Montana, USA. The nasal swab tested positive for equine influenza by Real-Time Quantitative Reverse Transcription Polymerase Chain Reaction (RT-PCR)...

The HIV-1-encoded accessory protein Vpu exerts several immunomodulatory functions, including counteraction of the host restriction factor tetherin, downmodulation of CD4, and inhibition of NF-κB activity to facilitate HIV-1 infection. However, the relative contribution of individual Vpu functions to HIV-1 infection in vivo remained unclear. Here, we used a humanized mouse model and HIV-1 strains with selective mutations in vpu to demonstrate that the anti-tetherin activity of Vpu is a prerequisite for efficient viral spread during the early phase of infection...

Inhalation of the toxic smoke produced by combusting tobacco products, primarily cigarettes, is the overwhelming cause of tobacco-related disease and death in the United States and globally. A diverse class of alternative nicotine delivery systems (ANDS) has recently been developed that do not combust tobacco and are substantially less harmful than cigarettes. ANDS have the potential to disrupt the 120-year dominance of the cigarette and challenge the field on how the tobacco pandemic could be reversed if nicotine is decoupled from lethal inhaled smoke...

Influenza A viruses (IAVs) are zoonotic pathogens that cause yearly outbreaks with high rates of morbidity and fatality. The virus continuously acquires point mutations while circulating in several hosts, ranging from aquatic birds to mammals, including humans. The wide range of hosts provides influenza A viruses greater chances of genetic re-assortment, leading to the emergence of zoonotic strains and occasional pandemics that have a severe impact on human life. Four major influenza pandemics have been reported to date, and health authorities worldwide have shown tremendous progress in efforts to control epidemics and pandemics...

Monitoring changes in influenza A virus genomes is crucial to understand its rapid evolution and adaptation to changing conditions e.g. establishment within novel host species. Selective sweeps represent a rapid mode of adaptation and are typically observed in human influenza A viruses. We describe Sweep Dynamics (SD) plots, a computational method combining phylogenetic algorithms with statistical techniques to characterize the molecular adaptation of rapidly evolving viruses from longitudinal sequence data...

Data from previous seasonal epidemics and pandemics have confirmed that pregnant women are at increased risk for severe influenza virus infection. Complications including fetal loss, higher rates of hospitalization and maternal death are most notable during the late gestational period. Antiviral therapy and influenza vaccination are recommended in pregnant women as both are effective and safe. This review discusses the epidemiology, pathophysiology, treatment and prevention of influenza virus infection in pregnancy, with a focus on recent developments...

Background: For the world can get rid of the HIV/AIDS pandemic by 2030, there is need for more to be done especially in the case of countries in Africa. In Nigeria, such efforts have included Faith-Based Organizations (FBOs) recognized as partners in the National Response Framework. However, the extent to which these FBOs contribute to efforts to control the pandemic will depend on their capacity. Therefore, this study aimed to ascertain the technical and managerial capacity of these FBOs to respond to the pandemic in Nigeria...

Vibrio cholerae O1 El Tor, the pathogen responsible for the current cholera pandemic became pathogenic by acquiring virulent factors including Vibrio seventh pandemic islands (VSP)-I and -II. Diversity of VSP-II are well recognized, however, studies addressing attachment sequence left (attL) sequences of VSP-II are few. In this report, a wide variety of V. cholerae strains were analyzed for the structure and distribution of VSP-II in relation to their attachment sequences. Of 188 V. cholerae strains analyzed, 81% (153/188) strains carried VSP-II, of those, typical VSP-II, and a short variant was found in 36% (55/153), and 63% (96/153), respectively...

Vibrio cholerae is a gram-negative motile bacterium capable of causing fatal pandemic disease in humans via oral ingestion of contaminated water or food. Within the human intestine the motile vibrios must evade the innate host defense mechanisms, penetrate the mucus layer covering the small intestine, adhere to and multiply on the surface of the microvilli and cause disease via the action of cholera toxin. The explosive diarrhea associated with V. cholerae intestinal colonization leads to dissemination of the vibrios back into the environment to complete this phase of the life cycle...

Zika virus (ZIKV) has recently caused a pandemic disease, and many cases of ZIKV infection in pregnant women resulted in abortion, stillbirth, deaths and congenital defects including microcephaly, which now has been proposed as ZIKV congenital syndrome. This study aimed to investigate the in situ immune response profile and mechanisms of neuronal cell damage in fatal Zika microcephaly cases. Brain tissue samples were collected from 15 cases, including 10 microcephalic ZIKV-positive neonates with fatal outcome and five neonatal control flavivirus-negative neonates that died due to other causes, but with preserved central nervous system (CNS) architecture...

Influenza and bacterial coinfection is a significant cause of hospitalization and death in humans during influenza epidemics and pandemics. However, the fundamental protective and pathogenic mechanisms involved in this complex virus-host-bacterium interaction remain incompletely understood. In this study, we have developed mild to lethal influenza and Streptococcus pneumoniae coinfection models for comparative analyses of disease pathogenesis. Specifically, wild-type and IL-1R type 1-deficient (Il1r1-/- ) mice were infected with influenza virus and then superchallenged with noninvasive S...

The B-lymphotropic Epstein-Barr virus (EBV), pandemic in humans, is rapidly controlled on initial infection by T cell surveillance; thereafter, the virus establishes a lifelong latent infection in the host. If surveillance fails, fatal lymphoproliferation and lymphomagenesis ensue. The initial T cell response consists of predominantly CD8+ cytotoxic T cells and a smaller expansion of CD4+ cells. A major approach to treating EBV-associated lymphomas is adoptive transfer of autologous or allogeneic T cells that are stimulated/expanded on EBV-transformed B cells...

Mycobacterium tuberculosis infection is responsible for a global pandemic. New drugs are needed that lack cross-resistance with the existing front-line therapeutics. A triazine antitubercular hit led to the design of a related pyrimidine family. The synthesis of a focused series of these analogs facilitated exploration of their in vitro activity, in vitro cytotoxicity, physiochemical, and Absorption-Distribution-Metabolism-Excretion properties. Select pyrimidines were then evaluated for their mouse pharmacokinetic profiles...
