BACKGROUND: Several studies have suggested that the association between aspirin and improved cancer survival is mediated through the mechanism of aspirin as thrombocyte aggregation inhibitors (TAI). The aim of this study was to provide epidemiological evidence for this mechanism assessing the association between overall survival and the use of aspirin and non-aspirin TAI in patients with colorectal cancer. METHODS: In this observational study, data from the Netherlands Comprehensive Cancer Organisation were linked to PHARMO Database Network...

Phylodynamic models are widely used in infectious disease epidemiology to infer the dynamics and structure of pathogen populations. However, these models generally assume that individual hosts contact one another at random, ignoring the fact that many pathogens spread through highly structured contact networks. We present a new framework for phylodynamics on local contact networks based on pairwise epidemiological models that track the status of pairs of nodes in the network rather than just individuals. Shifting our focus from individuals to pairs leads naturally to coalescent models that describe how lineages move through networks and the rate at which lineages coalesce...

From epidemiological studies and studies done evaluating microbiomes in infants, there is a strong signal that the infants born by elective cesarean section (C-section) develop microbiota that differs from those babies born by vaginal delivery. Epidemiological studies show increased odds ratios for the development of immunological disorders such as type 1 diabetes, celiac disease, asthma, allergic diseases as well as metabolic diseases such as obesity in babies born by C-section. These are interesting associations, and if supported by additional studies that rigorously control for confounding factors, they will have major public health implications...

Molecular epidemiology can help clarify the properties and dynamics of HIV-1 transmission networks in both global and regional scales. We studied 143 HIV-1-infected individuals recruited from four medical centers of three cities in South Korea between April 2013 and May 2014. HIV-1 env V3 sequence data were generated (337-793 bp) and analyzed using a pairwise distance-based clustering approach to infer putative transmission networks. Participants whose viruses were ≤2.0% divergent according to Tamura-Nei 93 genetic distance were defined as clustering...

Hepatitis B virus (HBV) and hepatitis C virus (HCV) are the major cause of the global burden of hepatitis. One of the main routes of transmission for both viruses is through exposure to infected blood, which includes sharing blood-contaminated syringes and needles. Human immunodeficiency virus (HIV) attacks the immune system and results in acquired immune deficiency syndrome and opportunistic infections. The objective of this study was to assess the epidemiology of HBV and HCV infections among HIV-infected people who inject drugs (PWID)...

The current Zika virus (ZIKV) outbreak became a global health threat of complex epidemiology and devastating neurological impacts, therefore requiring urgent efforts towards the development of novel efficacious and safe antiviral drugs. Due to its central role in RNA viral replication, the non-structural protein 5 (NS5) RNA-dependent RNA-polymerase (RdRp) is a prime target for drug discovery. Here we describe the crystal structure of the recombinant ZIKV NS5 RdRp domain at 1.9 Å resolution as a platform for structure-based drug design strategy...
