Zinc Lozenges May Triple Rate Of Recovery From Common Cold, Meta-Analysis Suggests
Amanda Macmillan reporting for TIME stated, “Zinc lozenges may triple the rate of recovery from the common cold, according to a new meta-analysis of three studies” published in Open Forum Infectious Diseases. There is a “caveat,” however. Researchers “looked at doses much higher than are commonly recommended by doctors, and the authors say that not all zinc lozenges on the market are effective.”
Comment: I use these all the time when I feel a cold coming on.
An early sign of osteoarthritis in the knees… next
Noisy Knees Could Signal Onset Osteoarthritis Research Finds.
Diane King writing in the Edinburgh News reported noisy knees may be an early sign of osteoarthritis, new research suggests. People who hear grating, cracking or popping sounds in and around their knee joints are more likely to develop the condition, say scientists. Researchers conducted a multi-centre observational study that included almost 3,500 participants at high risk of knee osteoarthritis. The chances of them developing pain symptoms over a period of up to four years increased with greater frequency of knee noise. It doubled when the noises were heard “often” and trebled for patients who said they “always” experienced them. The findings, published in the journal Arthritis Care & Research, may lead to new ways of diagnosing and treating osteoarthritis earlier, said the researchers. US lead author Dr Grace Lo, from Baylor College of Medicine in Houston, Texas, said: “Many people who have signs of osteoarthritis on X-rays do not necessarily complain of pain, and there are no known strategies for preventing the development of pain in this group of people. “This study suggests that if these people have noisy knees, they are at higher risk for developing pain within the next year compared with the people who do not have noisy knees.
Comment: Noisy knees are pretty common and so is osteoarthritis of the knees.
Bystander CPR, Defibrillation May Reduce Long-Term Likelihood Of Brain Damage, Death In Cardiac Arrest Patients, Study Suggests
Gene Emery writing for Reuters reported that research suggests that “when a bystander gives CPR or applies an automatic defibrillator to someone who has collapsed from cardiac arrest, the benefits persist for at least a year.” The study “concluded that the two techniques lower the long-term risk of death from any cause, brain damage or nursing home admission by one third in people who are still alive 30 days after their cardiac arrest.” The findings were published in the New England Journal of Medicine.
Comment: You should learn basic CPR. It might save the life of a loved one.
