Transplanting vaginal fluids from one woman to another could help tackle severe cases of a common bacterial condition, a study has suggested.
Bacterial vaginosis (BV) is thought to affect up to a third of women of reproductive age. It is caused when the balance of microbes in the vagina – known as the vaginal microbiome – becomes disturbed, with a drop in lactobacilli while other bacteria take over.
The condition is not generally serious, but it can increase the risk of contracting sexually transmitted infections, and of complications for pregnant women. It can also affect self-esteem; some women develop symptoms such as fishy-smelling discharge.
While BV can often be treated with antibiotics, in some women it recurs just weeks or months later meaning a steady dose of antibiotics might be necessary.
Now a small study has suggested severe BV could be treated by transplanting vaginal fluids from women containing a “healthy” collection of microbes.
The Royal College of Physicians explicitly tells doctors to promote e-cigarettes “as widely as possible” to people trying to quit. Public Health England’s advice is that vaping carries a small fraction of the risk of smoking.
… The U.S. reaction is “complete madness,” said Dr. John Britton, director of the U.K. Center for Tobacco and Alcohol Studies at the University of Nottingham. “The reality with smoking is, if you tell people to stop vaping, they will go back to tobacco and tobacco kills.”
.. In Britain, a review by Public Health England, an agency similar to the CDC, concluded that vaping is about 95% less dangerous than smoking. A leading British anti-tobacco charity, Ash, even called for e-cigarettes to be licensed as medicines and provided free to smokers trying to quit by Britain’s government-funded health system.
Vapour from e-cigarettes can kill off cells which line human airways, new research has suggested.
A study by scientists at the University of Adelaide in Australia found fumes from three types of apple-flavoured vaping liquid could destroy bronchial epithelial cells.
These line the respiratory system and are important for keeping the lungs and airways clean.
The researchers also discovered the vapour could interfere with the immune system, in particular by disrupting macrophages: white blood cells which digest and store unhealthy cells and foreign debris.
Shocking scan images show the damaged lungs of a 19-year-old boy whose vaping habit almost left him dead.
Anthony Mayo, 19, of Erie, Pennsylvania, became seriously ill last week, struggling to breathe, looking pale and feeling sick.
Doctors found his lungs had become severely congested with solidified vape oil, likened to cooking grease that hardens after being cooled.
It had caused Anthony, who had been vaping for around two years, to have ‘the lungs of a 60-year-old, two-pack-a-day, smoker’, his father, Keith Mayo, was told.
He revealed Anthony liked to try different flavours, and has previously vaped blue raspberry, Swedish fish, cotton candy and cinnamon toast crunch.
Anthony also vaped THC on occasion, which is the psychoactive ingredient in marijuana.
PROVIDENCE, Rhode Island– A 25-year-old woman walked into an emergency department in Providence, Rhode Island, complaining of generalized weakness, fatigue, shortness of breath… and an unusual symptom you don’t see every day.
She was turning blue. Literally.
Physicians Otis Warren and Benjamin Blackwood wrote about the case in a study published in the New England Journal of Medicine on Thursday.
They attributed her blueness to a numbing agent the woman was using, which deadens nerve endings in the skin.
What have we have found so far?
- Puff flow rate alters the nature of the aerosol, so users can control the strength of each puff simply by altering the way they puff.
- E-cigarette users change their puffing flow rate when they switch flavors or nicotine levels and are altering their exposure to harmful or potentially harmful constituents.
- For a given e-cigarette brand and flavor, there is a wide range of use behaviors, such as puff flow rates and puff durations.
- Machine replays of vapor behaviors show exposure varies over a wide range for any given product.
- Some e-cigarette users puff all day long, whereas others puff in more discrete time intervals, similar to smoking.
- Even if there is less nicotine per puff in some cases for e-cigarettes compared to cigarettes, e-cigarette users can indeed consume the same amount or more nicotine in a day compared to smoking.
