Vaping Can Lead to Chronic Disease in Lungs known as “Popcorn Injury”

In yet another serious health alert on e-cigarette use, researchers have documented first-ever case of a new form of damage from Vaping products in a youth which is similar to “popcorn lung,” a condition seen in workers exposed to food flavouring fumes in microwave popcorn factories.

If inhaled, the chemical called diacetyl causes bronchiolitis, which is characterized by the small airways of the lungs becoming inflamed and obstructed.

The 17-year-old patient who narrowly avoided the need for a double lung transplant suffered with this new type of vaping-related injury.

A team from Lawson Health Research Institute in London, Ontario, and University Health Network (UHN) in Toronto described the life-threatening bronchiolitis in a previously healthy 17-year-old male who initially presented for care after a week of persistent and intractable cough and was eventually hospitalized and put on life support.

After ruling out other causes, the team suspected flavoured e-liquids as the cause. The youth’s family reported that he vaped daily using a variety of flavoured cartridges and used tetrahydrocannabinol (THC) regularly. THC is the chemical responsible for most of marijuana’s psychological effects.

“This novel disease pattern of airway injury associated with vaping leading to chronic obstruction appears to be distinct from the alveolar injury characterizing the EVALI (e-cigarette or vaping product use-associated lung injury) have been described cases recently reported in the US, and the seven confirmed or probable cases in Canada, highlighting the need for further research and regulation of e-cigarettes,” elaborated lead author Dr Karen Bosma, Associate Scientist at Lawson.

The case study, published in CMAJ (Canadian Medical Association Journal), provides detailed medical information on the extent and type of injury as well as treatment.

“This case of life-threatening acute bronchiolitis posed a diagnostic and therapeutic challenge,” the authors wrote.

“Given the patient’s intense vaping exposure to flavoured e-liquid and negative workup for other causes of bronchiolitis, we suspected that bronchiolitis obliterans might have been developing in this patient as in microwave popcorn factory workers exposed to occupational inhalation of diacetyl.”

The youth narrowly avoided the need for a double lung transplant, but now has evidence of chronic damage to his airways.

He is still recovering from his lengthy stay in the intensive care unit, and is abstaining from e-cigarettes, marijuana and tobacco.

“This case may represent the first direct evidence of the lung disease most expected to result from e-cigarette use,” said Dr Matthew Stanbrook, Deputy Editor, CMAJ. (IANS)

Global Warming Can Make You Fall ill More Often: Study

The study said that increased heat may cause illness through undernourishment in a number of ways: reducing appetites, provoking more alcohol consumption, reducing motivation or ability to shop and cook and exacerbate any undernutrition

Global Warming is likely to increase illnesses caused by undernutrition, due to the effects of heat exposure, researchers have warned.

For the study published in the journal PLOS Medicine, the researhers analysed daily hospitalisation data covering almost 80 per cent of Brazil between 2000 and 2015.

They studied the link between daily mean temperatures and hospitalisation for undernourishment according to the International Classification of Diseases.

“The association between increased heat and hospitalisation for undernutrition was greatest for individuals aged over 80, and those 5 to 19 years,” said the researchers from Monash University, Australia.

The researchers found that for every 1 degree Celsius increase in daily mean temperature during the hot season, there was a 2.5 per cent increase in the number of hospitalisations for undernutrition.

“We estimated that 15.6 per cent of undernutrition hospitalisations could be attributed to heat exposure during the study period,” said study’s lead author Yuming Guo.

The study said that increased heat may cause illness through undernourishment in a number of ways: reducing appetites, provoking more alcohol consumption, reducing motivation or ability to shop and cook and exacerbate any undernutrition, resulting in hospitalisation.

“Climate change is one of the biggest threats to the reduction of hunger and undernutrition, especially in low and middle-income countries. It has been estimated that climate change will reduce global food availability by 3.2 per cent and thus cause about 30,000 underweight-related deaths by 2050,” the report said.

“It is plausible to speculate that climate changes could not only increase the rate of undernutrition in the most affected areas of the globe, but at the same time, impair individuals’ capacity to adapt to projected rises in temperature,” said the researchers. (IANS)
