A new study carried out in Canada indicates that we hear speech also through our skin. The study says that our skin assists with hearing speech, and detects puffs of air produced by the speaker with certain sounds made. This is the first study of its kind to exhibit that our ears do not do all the work in hearing what another person says.

The study was carried out by Professor Bryan Gick from the Department of Linguistics, University of British Columbia, in Vancouver, Canada and PhD student Donald Derrick and was published in the November issue of Nature.

During the study, Gick and Derrick found that by directing puffs of air at skin, the hearer’s discernment of spoken syllables could be biased.
Gick, also a member of Haskins Laboratories, an affiliate of Yale University in the US, said the findings reveal: “We are much better at using tactile information than was previously thought. We are already aware of using our eyes to help us interpret speech, such as when we lip-read or observe facial features and gestures. Our study shows we can do the same with our skin, ‘hearing’ a puff of air, regardless of whether it got to our brains through our ears or our skin.”

English is one of the few languages that rely on some syllables being aspirated. This means that the speaker uses varied bursts of breath to certain sounds. The sounds ‘pa’ and ‘ta’ are possible only due to these puffs of air, whereas for sounds like ‘ba’ and ‘da’ aspiration is not used.

A new study estimates that Americans suffering with diabetes could increase dramatically over the next quarter of the century. This would lead to the cost of healthcare increasing to a whopping $336 billion, triple the current levels.

Dr. Elbert S. Huang from the Department of Medicine at the University of Chicago, Illinois, did the study together with colleagues. A writeup on the study is featured in the Diabetes Care magazine December issue.

The research team developed a ‘Markov model’. The model of diabetes costs took into consideration a few trends left out by models developed previously. These include natural history of the condition, risk factors, and the effects of the treatments.

Changes in the diabetes population over time, baby boomer effect, recent surges in the US obesity rates, and the development of complications that affect the eyes, kidneys, circulation, and nervous system were also considered while carrying out this study.

Markov modeling is increasingly integrated into tools that attempt to forecast complex systems’ behavior in the future. These range from the study of diseases to reliability engineering.

The researchers said, “”We built this model to improve the budgetary and health outcome information available to federal policymakers. The model provides a rigorous assessment of the future burden of diabetes that accounts for the natural history of the disease and recent advances in treatment.”

The results showed:

Diagnosed and undiagnosed diabetes will rise from 23.7 to 44.1 million Americans between 2009 and 2034.

65% of people would be obese, with the distribution of obesity in the population remaining the same.

Annual spending on healthcare for diabetes will increase $113 billion to $336 billion between 2009 and 2034.

Drug rehab for prisoners in the United Kingdom has been “undermined” by government in-fighting, said the former British drugs tzar. Mike Trace, who oversaw the government’s drug policies during the administration of Tony Blair, told the BBC News during an interview that the Department of Health was relying too heavy on methadone treatments instead of other, non-medicinal ways to curb the drug addiction of the nation’s prison population.

"When they (inmates) see the healthcare professionals they are offered,” Trace said, “sometimes the only choice they are offered, is a prescription of some type, which means their motivation to try to remain drug-free can be undermined. We see that regularly on a week-by-week basis."

Trace is now part of a charity that advocates against the use of methadone and other drug-related treatments and for bringing the types of treatment typically found in a drug rehab center to prisoners in the UK.

There are many reasons for people who are unhappy with their smile to turn to cosmetic dentistry for a solution. Some people have discolored teeth from years of smoking, while others have chips or cracks. In some cases, it’s simply a matter of people having misaligned teeth that gives them a “crooked” smile. Not having great teeth can make anyone feel unhappy with their looks and self-conscious about their appearance.

One of the most popular options for fixing these types of dental issues is porcelain veneers. These are very thin layers of porcelain that are bonded to the front side of a person’s row of teeth. Porcelain veneers can smooth over cracks, misalignments and other flaws in a person’s gum line along with making even the most heavily-stained teeth look white again. Veneers are easy to apply and affordable, making them a great choice for people who want to have a better smile.

Nera Agabiti of Italy’s Department of Epidemiology led a team of researchers to determine if there were any significant patterns on the fact that poor people go to hospital more than the rich people. Agabiti used the data collected from hospital discharges from four major cities in Italy for the year 2000 focusing on several high-risk diseases such as COPD and asthma. Their study proved statistically that poor people were admitted into a hospital more so than rich people, with COPD being associated with the most admissions.

The team analyzed 9,384 hospitalizations and found that the majority were men from Rome, with an average age of 54. Males also tended to be more vulnerable than females to hospitalization for all studied conditions except for asthma. This finding was surprising as asthma is more prevalent in males. Yet, this study confirmed earlier ones that asthma care is greater for men than it is for women. In general, the hospitalization rate was greater in the poorest people with COPD-compromised patients having the highest rate.

Highlights of the study showed that poor people need more hospital care, yet it encouraged future studies to focus on economic, structural, and cultural factors that may affect an impoverished person’s access to medical care. Additional studies also confirmed causation between preventative health care which would lower the risk for otherwise avoidable hospitalizations. In Italy, this widening chasm between the income levels obviously affects health care. Based on these facts, there is an apparent need for providing and improving primary health care to lessen the unnecessary high amount of hospital admissions within the lower income bracket.
