Handshakes and Health

A new study in the British Medical journal Lancet suggests the strength of a person's hand-grip could predict the risk of heart attacks and strokes and is a stronger predictor of death than blood pressure checks. The international study, involving almost 140,000 adults in 17 countries during four years found weak grip strength is linked with shorter survival and a greater risk of having a heart attack or stroke. It also found that grip strength is a stronger predictor of death than systolic blood pressure. Grip strength was assessed using a handgrip dynamometer. Reduced muscular strength, which can be measured by grip strength, has been consistently linked with early death, disability, and illness.

Four Vaccine Myths Debunked

They cause autism: The origin of the myth was from a study by Dr. Andrew Wakefield. Most of Dr. Andrew Wakefield's co-authors withdrew their names from the study in 2004 after learning he had been paid by a law firm that intended to sue vaccine manufacturers. The same year, the Institute of Medicine reviewed evidence from the US, Denmark, Sweden, and the UK and found no connection between vaccines and autism. Around 2010, another British medical journal concluded Wakefield's study misrepresented or altered the medical histories of all 12 of the patients whose cases formed the basis of his study.

The Lancet retracted Wakefield's paper in 2010 and he lost his medical license.

They contain poison: The cause was from a preservative and Thimerosal is no longer used in vaccines. In 2001, the FDA stopped issuing licenses for children's vaccines containing it. The preservative has been used for decades and still is in adult vaccines. There have been many studies and none of them show a correlation with autism or other serious side effects, the FDA says.

Doctors and insurance companies promote vaccinations to drive profits: Some insurers pay the cost of vaccinations to prevent paying more later, when a patient gets sick. A 2009 study found that up to a third of doctors actually lose money when giving vaccines.

The diseases they help prevent are long gone: One example of this effect is before the measles vaccine was introduced in the 1960s, there were between 3 to 4 million cases a year, resulting in 400 to 500 US deaths. Measles vaccination in the US has reduced the rate of infection in the population by 99% when compared to times when no vaccine was available. Measles has been on an uptick this year, because so many children have not been vaccinated against it.

Joseph Lister

The idea of clean operating rooms did not exist until Joseph Lister began his practice of antisepsis in the 1860's. He introduced washing surgical instruments in carbolic acid, and keeping the operating area clean and sterile. He used it on the incision wound, dressings, and instruments. It was a revolutionary change for hospitals. Lister discovered that the infections in wounds which caused so many surgical deaths were not caused by the miasma in the air, but by something entirely different.

In his article in The Lancet of 21 September 1867 and his book 'Antiseptic Principle of the Practice of Surgery' he explained the cause was microorganisms that traveled from the surgeon’s hands onto the wound. Because of his miraculous results in operative and post-operative infection, Lister is considered to be one of the founders of modern surgery.

In 1893 Dr. J.C. Bloodgood (his real name) insisted on surgical glove use by his entire surgical team. This was followed by W. Steward Halstead's adoption of surgical gloves at Johns Hopkins that gained national exposure. Halstead is generally credited with the glove's discovery, which is not true.

Listerine was formulated by Dr. Joseph Lawrence and Jordan Wheat Lambert in St. Louis, Missouri, in 1879. Joseph Lister had nothing to do with it, other than it was named after him.
