Should adult kids get a COVID-19 test before a visit home?
Ask the doctor
Q. Should I make my kids get tested for COVID-19 before they come to visit me?
A. As we go to press, in most communities in the United States and Europe, the virus still is widespread — particularly among young adults. Many young adults who become infected do not develop symptoms, and therefore may not suspect they are infected. Worse, they may be shedding the virus and able to infect others. Older people are more vulnerable to becoming severely ill from the virus than young adults (although some young adults and even children can become very ill). So if my kids had symptoms that might indicate they had COVID-19, I'd ask them not to come. If they had no symptoms but were living in a "hot spot," I'd ask them to get tested before they traveled — and not to visit if they tested positive. I would hate not to see the kids, but it's a sacrifice we have to make until we control the virus.
Atrial fibrillation: Shifting strategies for early treatment?
For people recently diagnosed, taming the heart's rhythm rather than slowing it down may be a better approach.
The heart rhythm disorder known as atrial fibrillation (afib) occurs when the heart's electrical system goes awry. Instead of the heart's natural pacemaker creating a steady beat, the heart's upper chambers (atria) pulsate rapidly — up to hundreds of times per minute. Most of the electrical impulses telling the lower chambers (ventricles) to contract don't get through but many do, triggering a racing, irregular heartbeat that can leave people dizzy, breathless, or fatigued.
Therapies to tackle this common arrhythmia have improved over the years. Now, new findings suggest it may be time to rethink the treatment for people newly diagnosed with afib (see "Afib: Rhythm vs. rate control").
A different type of heart attack
Spontaneous coronary artery dissection is an underrecognized but important cause of heart attack, especially in younger women.
Most heart attacks happen when a blood clot blocks an artery feeding the heart. But a small percentage result from a tear in the inner wall of one of the heart's arteries. The resulting flap or swelling inside the artery wall obstructs normal blood flow. Known as a spontaneous coronary artery dissection, or SCAD, the condition strikes both sexes but is more common in women.
In women who are under 50, SCAD is the most common reason for acute coronary syndrome. This medical emergency refers to inadequate blood flow to the heart; it includes both heart attacks and unstable angina (sudden chest pain that occurs at rest).
Predicting low-risk prostate cancer
New calculators can estimate the chance your cancer might — or might not — become more aggressive.
Active surveillance is a popular option for men with low-risk prostate cancer, defined as a tumor that is confined to the prostate gland and unlikely to grow or spread. It involves monitoring prostate-specific antigen (PSA) levels in the blood for changes and having regular digital rectal exams to look for abnormal areas on your prostate.
During active surveillance, you have a PSA test and a digital rectal exam every six months and prostate biopsies approximately every other year. If your PSA level rises, your doctor will likely recommend a prostate MRI or an immediate prostate biopsy to see if the cancer has become more aggressive. If so, you and your doctor can decide whether to continue with active surveillance and have another biopsy six months or a year later, or move ahead to treatment, such as radiation, hormonal therapy, or surgery.
Certain foods and drugs may lower risk of colon cancer
In the journals
Colon cancer prevention involves following a healthy lifestyle — for instance, exercising and not smoking — and periodically getting a screening test such as a colonoscopy. But what impact do diet and medications have? A recent review of 80 statistical analyses published over the last 40 years explored this question. The review was published online Oct. 1, 2020, by the journal Gut.
Over all, the results were disappointing in that no specific drug, food, or supplement stood out in the body of evidence. Yet some of the reviewed studies did show a link between a lower risk of colon cancer and use of nonsteroidal anti-inflammatory drugs (NSAIDs) — such as aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve) —and a higher intake of fruits, vegetables, and fiber. But other studies did not.
Radiation after prostate cancer surgery may not be necessary
In the journals
Many men with prostate cancer who have a radical prostatectomy (prostate removal) receive radiation therapy afterward to wipe out any residual cancer cells. Alternatively, men can choose to delay radiotherapy and be monitored for evidence of prostate cancer activity, such as a rising blood level of prostate-specific antigen (PSA). If PSA testing or an imaging test like an MRI shows cancer, these men can then consider radiation therapy.
According to the findings of an analysis published online Sept. 28, 2020, by The Lancet, there is no clear benefit of immediate radiation over monitoring with later radiation therapy as necessary. Since some men will never need radiotherapy, this means that by forgoing immediate treatment, they can avoid potential side effects like incontinence and bowel problems.
Why do my legs swell at the end of the day?
On call
Q. I would occasionally get some swelling in my legs. But now I notice it by late afternoon every day. I otherwise feel fine. Should I be worried?
A. It sounds like you have edema, swelling in your legs due to fluid in the soft tissues beneath your skin. This usually occurs when pressure from the fluid inside your veins is high, which forces water out of the blood vessels and into the surrounding tissues.
Unlocking the mystery of chronic pelvic pain syndrome
The condition is an all-too-real problem for men, and one of the more difficult to treat.
After age 50, men often have periods of discomfort "down there." It could be a cramping, aching, or throbbing pain in and around your pelvis and genitals. You also may have issues in the bedroom and bathroom. While the problems are real, the cause is often difficult to pinpoint.
It's called chronic pelvic pain syndrome (CPPS) — also known as chronic prostatitis — and it's one of the most puzzling and difficult-to-manage conditions for older men.
The best way to beat colon cancer
When do you need to get screened, and how often?
One of the deadliest cancers can be prevented or detected at a curable stage if you follow recommended screening guidelines.
Colon cancer is the second most common cause of cancer deaths in the United States, according to the American Cancer Society (ACS). The good news is that the death rate has steadily dropped over the past several decades among older adults. (However, among people under 55, death rates from colon cancer have grown slowly, but steadily, since 2008.)
Blood test could find Alzheimer’s disease before symptoms appear
In the journals
Researchers are close to finding early cancer with a blood test. They may soon do the same with Alzheimer's disease. A new blood test called p-tau217 has shown great promise in diagnosing people with the disease, according to findings published online July 28, 2020, by JAMA.
The test looks for a specific type of tau protein in the blood. In people with Alzheimer's, tau protein in the brain forms tangles. Accumulation of tau protein tangles along with beta-amyloid deposits is thought to play a key role in how the disease develops.
