Healthy Gums May Lead to Healthy Lungs (Dental Tribune)
Maintaining periodontal health may contribute to a healthy respiratory system, according to research published in the Journal of Periodontology. A new study suggests that periodontal disease may increase the risk for respiratory infections, such as chronic obstructive pulmonary disease (COPD) and pneumonia. These infections can be severely debilitating and are one of the leading causes of death.
The infections are caused when bacteria from the upper throat are inhaled into the lower respiratory tract…More…
The main trigger for a heart attack is not vigorous exercise or stress — it’s air pollution, according to a study published in The Lancet this month.
Researchers found spending time in traffic, whether as a driver or pedestrian, tops the list of ‘last straw’ risk factors that bring on a heart attack.
Polluted air contains particles of dust and soot less than ten microns wide (one micron is a millionth of a metre) which get into the lungs and cause inflammation…More…
The sweet smell of candles or air fresheners make many American homes smell nice, but do you know all the chemicals that can be found in the fragrances? According to indoor air quality experts at the Oregon Environmental Council, some of those chemicals could have a wide-range of health effects.

“Sometimes it can just be a matter of a little bit of a cough and itchy eyes and you don’t know why,” [OEC’s Jen] Coleman said. “That can be an air quality problem”…More…
The musical instruments kids play in school bands and orchestras are traveling denizens of bacteria and fungi, say the authors of a new study. Music education is great for kids, they note, but please, please wash the instruments!
Researchers at Oklahoma State University bravely examined 13 instruments that belonged to a high school band. Six of the instruments had been played the previous week and seven hadn’t been played in a month. Swabs were taken of 117 different sites on the instruments, including the mouthpieces, internal chambers and even the carrying cases.
The researchers found 442 different bacteria, 58 types of mold and 19 types of yeast. Many of the bacteria were species of Staphylococcus, which can cause staph infection. Most of the bacteria can cause illness, the authors noted. Mold spores can contribute to the development of asthma. Even the instruments that had not been played recently harbored germs galore…More…
Eating Cheese Can Help Your Teeth (Guardian)
It might sound unlikely, but one of the best and easiest ways to combat acid erosion in your teeth is to eat a piece of cheese after every meal. Cheese contains alkali, which neutralises the acid left by the food you’ve consumed; drinks such as Coca-Cola, and sweet foods such as cakes and biscuits, are particularly acidic, so eating cheese after these will be effective.
Cheddar is best, because it contains the highest levels of alkali – soft cheese like brie or feta won’t have much of an effect. It doesn’t need to be a big chunk – just eating a small piece after your meal is a good way to improve the health of your teeth quickly and easily, without having to leave the dinner table.
Of course eating cheese is no substitute for good brushing but as an aid it can help to bring immediate results…More…
The Transportation Security Administration (TSA) recently posted test results regarding radiation emitted from some passenger and luggage screening equipment. The reports included calculation errors, missing data, and anomalies, prompting the TSA to announce it will retest all radiation-emitting full-body scanners and other baggage screening equipment that had inaccurate reports.
Hidden financial conflicts-of-interest are sneaking into published drug research through the back door, warns an international team of investigators, led by researchers from the Jewish General Hospital’s Lady Davis Institute for Medical Research and McGill University in Montreal.
More and more, policy decisions and what medications doctors prescribe for their patients are being driven by large “studies of studies,” called meta-analyses, which statistically combine results from many individual drug trials.
Led by Dr. Brett Thombs and McGill graduate student Michelle Roseman, the team found that important declarations of financial conflicts-of-interest in individual drug trials disappeared when those studies were combined in meta-analyses. Their results will be published in the March 9 issue of the Journal of the American Medical Association (JAMA)…More…
