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.

Landmark Nepal Survey Estimates Nearly 400 Elusive Snow Leopards

Nepal's first nationwide survey of the threatened snow leopard estimated nearly 400 of the elusive big cats in the Himalayan nation, wildlife officials said Tuesday.

Habitat loss, climate change and poaching have greatly impacted snow leopard populations across Asia, listed as a "vulnerable" species by the International Union for Conservation of Nature (IUCN).

But the survey offers a rare shot of hope, confirming numbers lie at the upper end of the previous estimates.

With thick grey fur dotted with dark spots, and large paws that act as natural snow shoes, the species are difficult to spot and quick to hide, making field research challenging.

"This is a historic step in Nepal's snow leopard conservation journey," Haribhadra Acharya, senior ecologist at the Department of National Parks and Wildlife Conservation, told AFP.

"This is the first time we are getting authentic data with the great effort of researchers," he said.

An estimated total of 397 snow leopards were counted, determined through motion-sensor camera and genetic analysis in seven key areas.

It offers the most comprehensive national estimate of snow leopards -- also known as the "ghosts of mountains" -- previously estimated by the IUCN to be in the range of 301-400.

Snow leopards are the least studied of the big cats globally due to their low population density and remote mountain habitats they inhabit.

"Nepal has only two percent of the size of the snow leopard habitats globally, (yet) we host 10 percent of the total estimated population", Ghana S Gurung, country representative of WWF Nepal, told AFP.

"More importantly, we are the second smallest country in terms of snow leopard habitat size after Bhutan, (but) we hold the fourth largest population," he added.

The Snow Leopard Trust, a US-based conservation group, says the exact total number is not known but that "there may be as few as 3,920 and probably no more than 6,390" across 12 countries in Asia.

Although conservationists have welcomed the new population estimate, many remain concerned about the threats posed by climate change and infrastructure development.

"New road construction, installation of transmission lines, and increased human activity in search of herbs are disrupting snow leopards' habitats in the Himalayas," said Acharya, one of the lead researchers.

Experts say the increasing avalanches in the mountains -- where climate change is exacerbating extremes of weather patterns -- are another threat.

Nepal has been praised worldwide for its efforts to protect wildlife which have helped several species, including tigers and rhinos, to return from the brink of local extinction.

The country's conservation efforts have helped to triple its tiger population to 355 since 2010 and to increase one-horned rhinoceros from around 100 in the 1960s to 752 in 2021.
