Nearly 25 million adults and children in the United States have been diagnosed with hay fever… and millions more probably have it without being diagnosed. But a study in the Journal of Allergy and Clinical Immunology shows that a hay fever vaccine developed for mice not only works… it works quickly. Human vaccines for some forms of human allergy already exist, including hay fever, but they take three to five years to be effective. Scientists hope the new vaccine in development may change how people approach allergy season.
Egg freezing has become almost common among upwardly mobile young women, but a new study finds that holding off kids for work doesn’t have much to do with it. Rather, the study presented to the European Society of Human Reproduction and Embryology shows that a much higher proportion of women are freezing their eggs because they haven’t found a man they want to have a family with.
And finally… here’s more evidence that there really may be such a thing as junk food addiction. A study in the journal Appetite shows that people who quit eating junk food suffer withdrawal symptoms that are remarkably like someone stopping drug use. Researchers say symptoms like sadness, irritability, and cravings peaked in the first two to five days after quitting junk food… and then tapered off.
This year’s flu season is barely over but a new analysis predicts that next fall’s flu vaccine is likely to be just as ineffective as this year’s. The study in the journal Clinical Infectious Diseases estimates that next fall’s flu vaccine will be only 20 percent effective against the dominant strain of influenza A. However, that’s better than nothing, so health officials are likely to say a flu shot is still worth it. Researchers say mass production of the vaccine produces mutations cutting its effectiveness by nearly 30 percent.
A lot of people take calcium supplements for bone health. But a new study finds that calcium may increase the risk of one kind of colon polyps that can later turn cancerous. The study in the journal Gut shows that calcium supplements raise the risk of sessile serrated polyps in the colon. Researchers say the increased risk is greatest in smokers and those with a previous history of polyps in the colon.
And finally, researchers say that the world’s supply of chocolate is in danger. It’s all because of a group of viruses in the six West African countries that produce 70 percent of the world’s cocoa. A study in the Virology Journal finds that the mysterious viruses can kill trees in less than a year. However, farmers are reluctant to take down diseased trees if they’re still bearing pods and that spreads the disease quickly. scientists hope to use gene editing to develop virus-resistant plants.
Synopsis: Human papilloma viruses are responsible for many cancers, especially cervical cancer and throat cancer. Vaccines exist for the major HPV’s that cause these cancers, yet relatively few eligible youths have gotten them. Experts discuss the toll of HPV and the reasons so many people avoid both vaccination and Pap tests that can detect cervical cancer early.
