Now breath test can detect lung cancer

A new breath test will now help in identifying and differentiating between the types of lung cancer in humans with high accuracy, a new study has suggested.
Metabolomx, a diagnostic company focused on the detection of the metabolomics signature of cancer from exhaled breath.

This seminal study, conducted at the Cleveland Clinic and led by Dr. Peter Mazzone, used Metabolomx’ first-generation colorimetric sensor array, and reported accuracy exceeding 80 percent in lung cancer detection, comparable to computerized tomography (CT) scan.
 Further, the study found that Metabolomx’ first-generation colorimetric sensor array could identify the subtype of lung cancer (small cell versus adenocarcinoma versus squamous cell) with accuracy approaching 90 percent.

“Our research shows that breath testing may help identify patients with lung cancer, as well as provide us with information that can help with treatment decisions, such as the type of lung cancer, its stage, and prognosis,” Dr Mazzone said.

“The accuracy of these non-invasive tests can be further augmented when combined with existing clinical predictors, such as health status and age,” he stated.

According to Paul Rhodes, founder and CEO of Metabolomx, the results demonstrate the broad potential for use of breath analysis in the early detection of lung cancer.
“These results show that the first generation of our breath test technology compares well with CT scans,” Rhodes noted.

Heavy lunch can make one sleepy while driving

A study has claimed that drivers who eat a big meal risk falling asleep while they are driving.

The study suggests that a big lunch, even without the effect of alcohol, can make it harder to concentrate on the road, leading to potentially dangerous mistakes.
Young men who did a test drive in a simulator after a fatty and sugary meal were more likely to drift into another lane than those who had a lighter lunch.  

While the effect of alcohol on motoring skills has been much researched, this study is one of the first to look at the impact of a full stomach.

 Twelve healthy young men attended Loughborough University’s sleep research centre
for a lunch of beef lasagne and a toffee yoghurt.
Half were given diet versions, totalling 305 calories, while the others ate the normal versions, which were much fattier and full of carbs, and had a calorie count of 922.  
All normally slept well but had only slept for five hours the previous night, something the researchers say would not be unusual.

 After lunch, they were put in a driving simulator and tasked with a two-hour-long, dull, monotonous “drive” along a dual carriageway with long straight sections and gradual bends.  

Young men were chosen because males under 30 are particularly likely to fall asleep at the wheel. Those who had the heavy lunch were more likely to drift into the other lane.
They started off not too badly, making just as many mistakes as the light lunchers for the first half hour but after that there was no doubt that they were sleepier. Worryingly, the men did not seem to realise that they were becoming weary.

Researcher Louise Reyner as said: “The mechanisms underlying why a heavy lunch enhanced aspects of sleepiness must remain a matter for speculation.  “However, high fat intake does elevate blood levels of the hormone cholecystokinin, which does increase lassitude,” she said.

Mothers who work part-time may be happier, healthier

A new study announced reveals that mothers who work part time may enjoy better overall health and fewer signs of depression compared to stay-at-home mothers or those who work full-time.

While previous research has examined a mom's happiness with full-time work vs. staying home, WebMD cites that there has “been little study of part-time work in particular, and its effect on motherhood, family life, and parenting in general.”

Researchers examined data from more than 1,300 mothers across the US, with information being collected from seven different interviews with the mothers over a 10-year period. In the study, part-time work constituted anything from one to 32 hours of work a week.

The results found mothers who worked part-time were “just as involved in their child's school as stay-at-home moms,” and more involved than moms who worked full time. "In addition, mothers working part time appeared more sensitive with their pre-school children and they provided more learning opportunities for toddlers than stay-at-home moms and moms working full time," according to the researchers.
