CPAP machines can reduce heart risk in people with prediabetes and sleep apnea

People with prediabetes who use a continuous positive airway pressure (CPAP) machine for obstructive sleep apnea may have a lower risk of heart disease, according to a small study from Montreal, Canada.

The researchers looked at 39 people who had both obstructive sleep apnea and prediabetes. Prediabetes is the condition in which blood sugar (sugar) is higher than it should be, but not yet high enough to be considered diabetes. Patients either used a CPAP machine or took a drug that they were told would help them breathe while they slept. After 2 weeks, the researchers found that the rest time on the day of those using the machine was lower than that of the control group. "These results suggest that better identification and management of OSA may have important clinical implications for prevention of cardiovascular disease," the authors wrote.

No, masks do not create carbon dioxide

Social media is full of people arguing that wearing masks is not healthy. Some claim that it causes carbon monoxide (CO2) buildup, which does more damage than it is supposed to prevent. However, this is not true, and it was shown again in a study published in the Annals of the American Thoracic Society.

In this small study, researchers looked at 15 healthy doctors and 15 veterans with chronic obstructive pulmonary disease (COPD). Each participant took timed walks and their respiratory status was measured after each. The researchers found no significant differences in gas exchange between the two groups, even in those with COPD who already had breathing problems.

The researchers didn't deny that wearing a mask can be uncomfortable, especially during exertion, but being uncomfortable isn't the same as getting too much CO2 or too little oxygen.

Avoiding cow's milk-based formulas at birth can reduce the risk of asthma

Babies who are at risk of developing allergies, usually because they run through their families, can reduce their risk of asthma or recurring wheezing if cow's milk formulas are avoided for the first three or more days of life. This was the result of a study of over 300 infants published on JAMA Network Open.

The researchers tracked the babies on their second birthday to see if they had asthma or wheezing. They found that babies who were not given a cow's milk formula had a lower incidence of both diseases. The researchers also said more research is needed.

The first person to be cured of HIV infection died

People living with HIV and those who love them were hopeful when Timothy Ray Brown became the first person to be cured of HIV infection by a bone marrow and stem cell transplant in 2007. Mr. Brown died of cancer on September 29th. He was 54 years old. The leukemia that killed him was a recurrence of cancer. Mr Brown had the same type of leukemia when he underwent the transplant in 2007. While the HIV was gone, the leukemia did not go away, so he successfully underwent another transplant the following year. Cancer returned in 2019.
