How can you protect yourself from both viruses?

With flu season here and the COVID-19 pandemic ongoing, what can people expect when these two illnesses meet?

It's anyone's guess.

"While we're in the midst of the COVID pandemic, there's a lot of uncertainty about what will happen when this collides with our yearly flu epidemic," says Dr. Mary Watson Montgomery, an infectious disease expert at Harvard-affiliated Brigham and Women's Hospital.

People with prediabetes — a condition in which blood sugar is elevated but not high enough to be considered diabetes — often go undiagnosed. That may put them at higher risk of cardiovascular disease and even early death, according to an analysis of 129 studies published in the July 18, 2020, issue of The BMJ.

The analysis, which combined data on some 10 million people, found that prediabetes raised the risk of dying from cardiovascular disease by 15% and from any cause by 13% over a median follow-up period of about 10 years. The mortality risk was even higher in people with prediabetes who also had coronary artery disease: they had nearly a 40% increased risk of dying within a median follow-up period of just three years. The study authors suggest that finding and addressing more cases of prediabetes could lead to a lower risk of future cardiovascular disease.

A specialized fall prevention program managed by nurses wasn't able to significantly reduce the rate of serious falls among high-risk adults over age 70, according to a study published July 9, 2020, in The New England Journal of Medicine. The STRIDE program (the name stands for Strategies to Reduce Injuries and Develop Confidence in Elders) was tested by the Patient-Centered Outcomes Research Institute and National Institutes of Health as a means of reducing falls among high-risk seniors.

Falls are a leading cause of injury in people 65 and older, with some three million adults heading to the emergency room each year with a serious injury caused by a fall. Program staff worked with individuals at least 20 months to identify and modify such risk factors as problems with walking or balance, hazards in the home that made a fall more likely, a history of low blood pressure when standing, and low vitamin D levels.

Get an approved blood pressure device and follow these steps.

Monitoring your blood pressure at home has always made good sense. Blood pressure is one of the main indicators of cardiovascular health, and taking measurements is an important way to manage chronic conditions between doctor visits.

Now, with a pandemic under way and fewer people visiting their doctors, the case for monitoring blood pressure at home has never been stronger. Home monitoring yields valuable information for you and your physician, who'll be counting on you to provide accurate blood pressure measurements when you talk on the phone or in a video chat.

A modest uptick in the amount of fruit and vegetables you eat can help ward off type 2 diabetes, according to a study published online July 8, 2020, by The BMJ. From a much larger study involving some 340,000 people from eight European countries, scientists selected 9,754 participants who were newly diagnosed with diabetes over a decade. Researchers compared the fruit and vegetable intakes of these people to those of about 13,000 participants who remained diabetes-free during the study period. Researchers also measured blood levels of seven key plant-derived nutrients, including vitamin C and brightly colored antioxidant pigments called carotenoids. People with the highest intakes of fruit and vegetables and the highest blood levels of the plant-derived nutrients were 25% to 50% less likely to get diabetes during the study period, compared with those who ate the least of these food groups or had the lowest nutrient levels. Even better, it didn't take a whole lot of extra green, red, yellow, and orange on the plate to make a dent in diabetes risk. The equivalent of only two-thirds of a medium apple or just over one-third of a cup of mixed fruit each day offered protection.

Not only can regular leg stretching help reduce cramps and muscle strains, it also may be another way to protect against heart disease and stroke. A study published online July 1, 2020, by The Journal of Physiology found that performing simple leg stretches can help improve blood flow throughout the body.

Researchers split 39 healthy people into two groups. One group didn't do any stretching. The other group performed four types of leg stretches five times a week for 12 weeks. The stretches focused on the hip, knee, and ankle. Each stretch was done for 45 seconds with a 15-second recovery. Afterward, the researchers found that the arteries in the lower legs of the stretching group had better blood flow and less stiffness. The stretching group also had lower blood pressure at the end of the study compared with their initial readings.

Millions of Americans get coughs and colds during the winter, and many head to the drugstore to pick up one of the hundreds of common medicines available without a prescription. But those products often contain multiple active ingredients that are potentially unsafe if combined. Here's how to safely choose the right over-the-counter medication for your symptoms.

Home delivery is just a few clicks away.

Lots of things can keep you from picking up a prescription at your local pharmacy. You may be stuck at home because of disability, illness, social distancing, or a lack of transportation. But the longer you go without your medication, the more your health is at risk. That's why it's important to know how to use home delivery services that bring prescriptions right to your door.

Local pharmacy delivery

Just like in the old days, some local pharmacies still send their own staffers to deliver prescriptions to their customers. The pharmacies are usually small and independently owned. You might expect that kind of service from them.
