We’ve shown that a simple ‘breath check’ can spot the patterns of molecules which are found in head-and-neck individuals in a small, early study. We now have to test these outcomes in larger research to discover if this could lead to a potential screening method for the condition. Dr Lesley Walker, Cancers Research UK’s director of cancer information, said: Cancer Research UK is certainly leading initiatives to boost early diagnosis of malignancy; it’s incredibly important to spot the disease as quickly as possible when it is better to treat effectively. These interesting initial results show promise for the development of a breath test to detect head-and-neck cancers which are generally diagnosed at an advanced stage.Related StoriesAustralian experts define key characteristics of metabolically healthy obeseNew research finds insufficient proof for usage of Omega 3 supplements in treating main depressive disorderComputerised cognitive behavioural therapy apt to be ineffective in depression treatment’We discovered bidirectional associations between unhappiness and obesity: obese individuals had a 55 % elevated risk of developing depression over time, whereas depressed persons had a 58 % elevated risk of becoming overweight,’ the authors compose. ‘The association between melancholy and obesity was more powerful than the association between depressive disorder and overweight, which displays a dose-response gradient.’ Sub-analyses demonstrated that the association between weight problems and later depression was even more pronounced among Americans than among Europeans, and more powerful for diagnosed depressive disorder weighed against depressive symptoms.
