2 questions to help in identifying alcoholics 

A new study has claimed that two easy questions could help determine potential or real drinking problem in people. The research alleged that a general practitioner could inquire these two questions “How often do the person have six or more drinks on one occasion?” and “As a result of a person’s drinking or drug use, did anything happened in the last year that they wish didn’t happen?” to detect hidden alcohol abuse, the Independent reported. 

Scientists from the University of Leicester, led by consultant in psycho-oncology Alex Mitchell found that the “optimal approach appeared to be two questions” followed by a possible four more and if that was completed then it “achieved an overall accuracy of 90.9 per cent and required only 3.3 questions per attendee.” If the two questions were used alone it correctly identified alcohol abuse in 87.2 per cent of cases as well as correctly identifying those who do not suffer with alcohol problems in 79.8 per cent of cases. Too large a questionnaire could be a long and drawn-out task to administer to each patient. 
Simple blood test to predict Alzheimer 

Researchers have reached a step closer to Alzheimer’s treatment by coming up with a new blood test which can predict the commencement of the disease in people.  Scientists from King’s College London and UK proteomics company, Proteome Sciences plc, analysed over 1,000 individuals, and have identified a set of 10 proteins in the blood which can foresee the start of disease, marking a significant step towards developing a blood test for the disease. The researchers used data from three international studies. Blood samples from a total of 1,148 individuals (476 with Alzheimer’s disease; 220 with ‘Mild Cognitive Impairment’ (MCI) and 452 elderly controls without dementia) were analysed for 26 proteins previously shown to be associated with Alzheimer’s disease. Lead author of the study Dr Abdul Hye, said that the proteins could predict whether someone with early symptoms of memory loss, or mild cognitive impairment, would develop Alzheimer’s disease within a year, with a high level of accuracy. Professor Simon Lovestone, senior author of the study added that Alzheimer’s begins to affect the brain many years before patients are diagnosed with it and most of the drug trials fail because by the time patients were given the drugs, the brain had already been too severely affected. A simple blood test could help in identifying patients at a much earlier stage to take part in new trials and hopefully develop treatments which could prevent the progression of the disease.
Sedentary behaviour detrimental for heart

A new study has revealed that sedentary behaviours may lower cardiorespiratory fitness levels.

According to the study by cardiologists at UT Southwestern Medical Center, two hours of sedentary behaviour can be just as harmful as 20 minutes of exercise is beneficial.The researchers said that sedentary behaviour may be an important determinant of cardiorespiratory fitness, independent of exercise and the negative effect of six hours of sedentary time on fitness levels was similar in magnitude to the benefit of one hour of exercise. Jarett Berry, Assistant Professor of Internal Medicine and Clinical Science and senior author of the study, said that previous studies have reported that sedentary behaviour was associated with an increased risk for cardiovascular outcomes; however, the mechanisms through which this occurs are not completely understood. Berry added that their data suggest that sedentary behaviour may increase risk through an impact on lower fitness levels, and that avoiding sedentary behaviour throughout the day may represent an important companion strategy to improve fitness and health, outside of regular exercise activity.

The study also found that when sitting for prolonged periods of time, any movement is good movement, and was also associated with better fitness and if one is stuck at your desk for a while, then they should shift positions frequently, get up and stretch in the middle of a thought, pace while on a phone call, or even fidget.
