Background & Aims. Patients with recurrent bleeding from gastrointestinal vascular malformations are a challenge to treat. We investigated the long-term efficacy and safety of thalidomide for refractory bleeding from gastrointestinal vascular malformations in an open-label, randomized study.
China is Worldâs Largest Energy Consumer. World consumption of energy has increased 5.6 percent in 2010, according to BPâs Statistical Review of World Energy. This is the largest increase since 1973, which happened to be a memorable year in energy history.
In 2012, the IEA estimated that the world energy consumption was 155,505 terawatt-hour (TWh), or 5.598 Ã 10 20 joules. This works out to 17.7 TW, or a bit less than the estimated 20 TW produced by radioactive decay on earth. From 2000â2012 coal was the source of energy with the largest growth.
