WEDNESDAY, April 21, 2021 (American Heart Association News) -- Some types of cancer may alter the appearance and function of the heart, according to new research that analyzed people's hearts before cancer treatment.An estimated 1.9 million people in the United States are expected to be diagnosed with cancer this year, according to the National Cancer Institute. Having a history of cancer is linked to a greater risk of cardiovascular problems: Older breast cancer survivors, for example, are most likely to die from cardiovascular disease, not breast cancer. Cancer and heart disease also share several risk factors, including obesity and tobacco use.But researchers are still trying to understand how much of the risk comes from the cancer itself versus common treatments that can be toxic...

WEDNESDAY, April 21, 2021 (HealthDay News) -- Outspoken pandemic denier Ted Nugent announced this week that he's tested positive for COVID-19, after 10 days of symptoms so severe that at times he "literally could hardly crawl out of bed."But despite his illness, the Republican rocker from Michigan remains skeptical about COVID vaccines."I haven't taken the vaccine, because nobody knows what's in it," Nugent said in a Facebook Live post announcing his diagnosis. "Actually, some people do know what's in it, and if you can't even honestly answer our questions of exactly what's in it, then why are you testing it on human beings and forcing it upon people in such a short time?"About half of Republican men agree with Nugent. In polls, as many as 49% say they won't get the shot.Americans need...

WEDNESDAY, April 21, 2021 (HealthDay News) -- As if the headaches and stuffy nose aren't bad enough, chronic sinus trouble often leaves patients foggy-headed and depressed. Now, new research suggests one possible reason why: Sinusitis may trigger changes in brain activity."Chronic sinusitis is incredibly common," said study lead author Dr. Aria Jafari. Upwards of 11% of all Americans are affected, added Jafari, an assistant professor with the University of Washington Sinus and Skull Base Center, in Seattle. The condition occurs when sinus tissue becomes swollen or inflamed because of an infection or perhaps an allergic reaction. Over time, the inflamed tissue thickens, much like calloused skin, the study authors explained. Those who develop problems with concentration and thinking may...

WEDNESDAY, April 21, 2021 (HealthDay News) -- A deadly chemical in paint strippers continues to kill workers despite its known dangers, a new study finds.The chemical methylene chloride, also known as dichloromethane (DCM), is a solvent found in paint strippers, cleaners, degreasers, adhesives and sealants. When inhaled, it produces large quantities of carbon monoxide that can cut off oxygen to the heart. At high doses, it switches off the brain's breathing center. Death can occur within minutes."It can make you feel dizzy, nauseous and eventually, you can become unconscious and die, because what it does is deprive your body of oxygen," said senior researcher Veena Singla, a senior scientist at the Natural Resources Defense Council in San Francisco."In a small, enclosed space like a...
