Other DVT risk factors
Cramped conditions on aircraft can increase the odds of developing potentially fatal blood clots but researchers said other factors may be at play too. Low pressure and low oxygen levels in aircraft may also contribute in some people to the risk of deep vein thrombosis (DVT).
Many people who suffer “non-ischemic” cardiac death – a cardiac death that is not related to restricted blood flow to the coronary arteries – appear to have structurally normal hearts, British researchers have found. In the “vast majority” of cases, sudden adult cardiac death is caused by ischemic heart disease – heart disease that is characterised by restricted blood flow to the arteries of the heart, Drs Mary N. Sheppard and A. Fabre of Royal Brompton and Harefield NHS Trust, London, note in a report in the medical journal Heart.
Linked to sleep
Research hints that not getting enough sleep each night, or getting too much sleep, may increase a person’s risk of developing non-insulin dependent (type 2) diabetes, independent of other factors. “Sleep duration may be a novel risk factor for the development of clinical diabetes,” conclude the researchers in the March issue of Diabetes Care.
Treating prostrate cancer
Men with prostate cancer may be put on hormone therapy, to block testosterone production in an effort to halt or slow tumour growth. While some health effects of so-called “androgen deprivation therapy” (ADT) for prostate cancer are clear-cut – for example sexual dysfunction – there is this whole set of less specific, more vague symptoms, like changes in mood, memory, feeling unwell and being tired.
A new study suggests that these symptoms are likely due to the fact that the patients are older, sicker and have more advanced disease. “Androgen deprivation is probably not playing a big role in causing these symptoms,” Dr Vahakn B. Shahinian of the University of Texas Medical Branch in Galveston said. – Source: Reuters
