Between You and Me: Here are three bits of information for health and pocketbook

By Leah S. Dunaief

Here are a couple of tidbits from the news that I think are worth sharing with you. 

First, good news for those who dislike having to endure colonoscopies, which I guess is all of us. A relatively recent diagnostic, this test has proven highly effective against colorectal cancers, but it essentially takes away two days from our lives: the day to prep by cleaning out the colon with a mighty laxative, an unpleasant procedure on its own, and then the afternoon to recover from the anesthesia at the end.

The FDA has now approved a simple blood test for detecting colon cancer when it is in the early stages and most likely can be cured. This is even easier than the fecal sample test, which is in turn easier than a colonoscopy but is not the most aesthetically pleasing.

The blood test, however, also leaves something to be desired. It has a poor record of finding precancerous growths, which a colonoscopy detects. These can be removed before they become malignant, but they have to be discovered.

Colorectal cancer is the second most common cause of cancer death in the United States, with 53,000 deaths expected this year. My father was among those felled by this disease many years ago, and had he lived long enough to have the benefit of the various diagnostic tests, his life might not have ended as it did. 

The idea is to have as many people over 45 tested as possible, and the blood test, called Shield by Guardant, can discover 87 percent of cancers that are at an early stage. But it only found 13 percent of large polyps. There is a false positive rate of 10 percent. Nonetheless, this is an advance in detection and perhaps an encouragement to be checked. As many as 50 percent of those who should be are not. For more information on this, look up the New York Times story published on Tuesday, July 30 or the New England Journal of Medicine on March 13 of this year.

Another interesting bit of news is the popularity of portable solar panels that cost some $217 each and work by plugging in to an electrical socket to give the home energy. They can be hung over the railing of a balcony or installed in yards and they are taking over the landscape in some towns in Germany. Each panel only produces enough electricity to power a small refrigerator, a laptop or even a portable air-conditioner in a bedroom. More than 500,000 of the systems have been set up, adding 10 percent more solar energy capacity to the country. Two-thirds of those were installed on buildings,“like hanging wet laundry in Italy,” commented one owner.

Part of the incentive for Germany is to move away from their dependence on Russian natural gas. It is also a great satisfaction for the people employing these systems to be taking steps toward providing a better environment. Most of the solar panels are made in China, although some, of lesser grade, are manufactured in Europe. These plug-in systems send the direct current (DC) produced by the panels from the sun to an inverter, which changes it to an alternating current (AC). Then they can be plugged into a conventional wall socket and feed power to the home. There are videos online explaining how these panels work and how to use them. Complete sets, which can be bought in big box stores, include mountings, an inverter, and cables, double the price.

A helpful concurrent development has been the small scale batteries that allow the panel users to store some electricity that can then be used in the evenings or when the sun is not shining. My guess is that before long, we will see those panels appear here.

The last item that caught my eye was about corn. Now, I love corn, especially on the cob. I enjoyed a lot of it fresh from the fields when my family visited relatives in the Catskills in my early years. Turns out, it’s a pretty healthy vegetable, if starchy, that is loaded with fiber. And fiber is good for us. It can even lower colon cancer risk.
