ABSTRACT
A literature study on the association between travel and venous thromboembolism (VTE) is conducted. Studies examining the risk of travel-associated VTE, predisposing factors and prophylactic measures are presented. It is concluded that the absolute risk of travel-associated VTE is low and holds a 2-4 fold increase after travel. The risk increases with duration, presence of other risk factors for VTE and extremes of height. Stockings reduces the risk of asymptomatic VTE. Heparin is presumed to constitute protection whereas there is no evidence of a prophylactic effect of acetylsalicylic acid.

New gene sequencing-based techniques and the large worldwide sequencing capacity have introduced a new era within the field of gut microbiota. Animal and human studies have shown that obesity and type 2 diabetes are associated with changes in the composition of the gut microbiota and that prebiotics, antibiotics or faecal transplantation can alter glucose and lipid metabolism. This paper summarizes the latest research regarding the association between gut microbiota, diabetes and obesity and some of the mechanisms by which gut bacteria may influence host metabolism.
