French Oncologist: Alternative Smoking Reduces Mortalities but Still Harmful

The World Health Organizations (WHO) estimates that there are around one billion smokers worldwide, a number that is not expected to decline in the foreseeable future and will likely remain steady until 2025.

An international expert in medical oncology said the concerned organizations should adopt a more realistic approach to banish smokers from cigarettes using an effective scientific methodology.

Dr. David Khayat, a renowned professor of oncology and medical oncologist in France, told Asharq Al-Awsat that “smoke-free alternatives could deliver a 10-fold reduction in smoking-attributable deaths; however, they are not harm free,” noting that “non-contagious diseases are the leading cause of death in the Middle East, accounting for 72 percent of mortalities.”

He also said “some common practices such as online shopping, regular dining in restaurants and humid weather encourage a lazy lifestyle.”

“The fundamental approach we adopted over the three past decades essentially relied on chemotherapy and hormone interventions. But the scientific research and innovation led us to advanced, more precise alternatives like the targeted therapy and immunotherapy,” he said. Khayat hailed “the discovery of another cancer-fighting treatment that targets the mutating proteins by killing the cells that contain them. These proteins are believed to be the reason behind the ability of endless division that some cancerous cells have.”

The French oncologist said “it’s important to know that cancer survives through mutations and single-cell DNA repair turnovers, which could be fought with targeted therapies,” adding that “other newly-discovered treatment methods, including stereotactic radiotherapy (or radiosurgery) help destroy tumors with high precision.”

The oncology professor said “in 2016, two researchers from Japan and the US discovered why cells sleep. Cancer is so malignant that it secretes somnifera - a sleeping pill - into the white blood cells, which causes them to go dormant. Then, scientists developed an innovative new approach: immunotherapy, a treatment method that contains antibiotic drugs to prevent lymphocytes from becoming inactive. This solution has changed the diagnosis of many cancers, including those found in the lungs, stomach and skin.”

“Nicotine, although addictive, is not the primary cause of smoking-related diseases such as cancer; smoking a cigarette means inhaling the smoke and the resulting burning ash, and this combustion process is the main reason behind many risks and toxins,” said Khayat.

Products that prevent combustion, such as electronic cigarettes, heated tobacco products and oral nicotine pouches, are “a less harmful alternative to conventional smoking.”

“While nicotine, the addictive substance, is still present in different levels in these alternatives, and thus does not make them completely risk-free, it is sufficient to shift smokers' interest away from inhaling cigarette smoke,” he concluded.



Should You Stretch before Exercise? After? Never? Here’s What to Know

For many people of a certain age, high school gym class began with reaching for their toes. Then, over the years, we were told it was better to stretch after exercise.

It turns out, both those things can be true, but the differing advice has created some confusion.

Stretching can help make you more flexible, improve range of motion in your joints — and feel good. David Behm, who researches human kinetics at Memorial University of Newfoundland in St. John’s, Canada, offers this advice on when to stretch and how to do it safely:

Warm up first

It’s almost always good to stretch, but it’s better if you warm up first, said Behm, author of "The Science and Physiology of Flexibility and Stretching." He recommends a light aerobic activity such as jogging, walking or cycling for five or 10 minutes.

Follow that with some static stretching, the traditional way of reaching and holding a position (think back to that gym class). You can then do activity-specific dynamic stretching, in which you warm up the muscles with repetitive movements like leg lifts.

Behm says one minute is "the magic number" for how long to do static stretching per muscle group without fatigue.

Expand your definition of 'stretching'

Should you always stretch before exercising? If it's traditional stretching, not necessarily.

The better question, Behm says, is, "Should people increase their range of motion? Should people have better flexibility? And that is yes, because it helps prevent injuries. It helps with health. But you don’t have to stretch to achieve that."

Resistance training, for instance, can be an effective form of stretching, he said. Doing a chest press increases range of motion in your deltoids and pecs, whether with barbells, dumbbells or machines, so there is no need to stretch beforehand. Just make sure to start with a small amount of weight to warm up and then add more to train.

"You probably don’t have to do extra stretching unless you’re a gymnast, a figure skater, or even a golfer who needs a great range of motion through that swing," Behm said.

Nor do you need to stretch first if you’re going for a leisurely run. Simply start with a slow jog to warm up and then increase the pace.

Don't do it if it hurts

After exercise, "light stretching is OK, as long as you don't reach a point where you're feeling pain," Behm said. Since your muscles will be warm by that point, overdoing it makes you more likely to injure yourself.

Foam rollers can help with muscle recovery and have been shown to increase range of motion as well as stretching.

Do some static stretching before sports

If you’re playing a sport, Behm said, static stretching beforehand helps reduce muscle and tendon injury.

"If you’re going to do an explosive movement, change of direction, agility, sprint, any of these explosive activities that involve your muscles and tendons," he said, "you’re going to be stronger if you do static stretching."

People can especially get in trouble when they go back to a sport they used to play, whether it's tennis, surfing or any sort of team activity.

Also, stretch both sides equally. Lacking flexibility on one side also can lead to injury.

Sounds simple. Why all the confusion? Different studies over the years have either encouraged or discouraged stretching before exercise. Behm says that partly because some studies didn't reflect real-life conditions, or were designed with elite athletes in mind, not regular people.

"If you’re Usain Bolt, it makes a difference," said Behm. Not so much for the rest of us.
