Implanted heart devices include pacemakers and implantable cardioverter defibrillators (ICDs), which monitor and correct abnormal heart rhythms. While very reliable, they are not perfect, and recalls of these devices affect thousands of people each year, according to a 2024 study. Testing the effectiveness and safety of cardiac devices is far more complicated than testing drugs. But efforts are under way to improve postmarket tracking of device complications by using electronic health records, Medicare databases, and registries developed in partnership with device manufacturers.

At some point, most older adults experience the occasional "senior moment" where they misplace an everyday object, lose their train of thought during a conversation, or forget why they walked into a room. Memory lapses like this are part of normal aging, but the problem can be exacerbated by issues like depression, stress, poor sleep, and medication side effects. If these episodes become so frequent or substantial that they interfere with a person's daily life or safety, it's time to see a doctor.

Treatments for severe carotid stenosis include a catheter-based procedure to insert a stent inside the carotid (carotid artery stenting) or surgery to remove the plaque inside the artery (carotid endarterectomy).

A small randomized trial in 2024 found that both self-adjustment and in-situ audiometry were effective strategies to match self-fitting hearing aids to personal hearing needs. However, self-adjustment devices had the best satisfaction rates and consistent use.

The FDA has approved three GLP-1 receptor agonist drugs for weight loss. The drugs not only lower blood sugar and weight, but also quiet inflammation, stimulate the production of antioxidants, help repair damaged DNA, and slow the aging of the body's cells. Evidence suggests that among people who use the drugs for diabetes and obesity, the drugs reduce the risks of kidney disease progression, heart attack, death from heart disease, death from COVID-19, and death from all causes by 15% to 35%.

Radiation therapy for prostate cancer used to involve weeks or months of treatment. Today, radiation delivery is moving toward higher doses given with fewer sessions over shorter durations. Results from a clinical trial show that the two types of therapy offer the same long-term benefits.

People with atrial fibrillation (afib) who own a smart watch capable of detecting the heart rhythm disorder may use it to track the frequency and duration of their bouts of afib. The information might help inform their physician's advice. However, afib notifications may cause people to become anxious and preoccupied with tracking their condition. For them, disabling the notifications may be a good idea.

There are three main treatment options for men whose prostate cancer has grown and become more likely to spread: surgical removal of the prostate, radiation to destroy the cancer cells, and hormone therapy to slow the cancer's growth. One aspect of treatment men should consider is the possibility of side effects. Understanding how common they are and their potential consequences can help men with their treatment choices.

Smart rings can do many of the same things a smart watch can, including heart rate monitoring, blood oxygen level measurement, and activity and sleep tracking.
