PERSONALISED MEDICINE
What is personalised medicine? Personalized Medicine refers to the tailoring of medical treatment to the individual characteristics of each patient to classify individuals into subpopulations that differ in their susceptibility to a particular disease or their response to a specific treatment. Preventative or therapeutic interventions can then be concentrated on those who will benefit, sparing expense and side effects for those who will not. http://www.personalizedmedicinecoalition.org/about
What is personalised medicine? A personalized medicine approach to providing health services involves integrating genomics technologies and advances with clinical and family histories in order to more coherently tailor therapeutics to individual patients Issa AM (2007) Personalized medicine and the practice of medicine in the 21st century. Mcgill J Med. 10(1):53-7.

GENOMICS IN ACTION
Genetics and Flu Research involving University of Edinburgh researchers To test the role of IFITM3 in human influenza virus infection, we assessed the IFITM3 alleles of individuals hospitalized with seasonal or pandemic influenza H1N1/09 viruses. We find that a statistically significant number of hospitalized subjects show enrichment for a minor IFITM3 allele (SNP rs12252-c) these data reveal that the action of a single intrinsic immune effector, IFITM3, profoundly alters the course of influenza virus infection in mouse and humans Everitt AR et al (2012) IFITM3 restricts the morbidity and mortality associated with influenza. Nature. 484(7395):519-23.
Sequencing and MRSA Research led by University of Edinburgh Researchers We carried out a Bayesian phylogenetic reconstruction on the basis of the genome sequences of 87 S. collected from patients in three continents over a 53-year period phylogeographic analysis indicates that EMRSA-16 spread within the UK by transmission from hospitals in large population centers in London and Glasgow to regional health-care settings, implicating patient referrals as an important cause of nationwide transmission.
