Sepsis is the immune system's overwhelming response to infection. It can lead to a dramatic drop in blood pressure that damages vital organs and causes death. Sepsis risk factors include older age, recent surgery, chronic illness, artificial joints, or a suppressed immune system.

A 2024 study found that two doses of the recombinant zoster vaccine to prevent shingles remains highly effective after four years.

A 2023 study confirms prior research showing that men with low testosterone levels who use testosterone replacement therapy for 14 months are not at a higher risk for prostate cancer over the following several years.

Two sexual issues that many men encounter with age are anorgasmia (trouble achieving an orgasm during sex) and delayed orgasm (in which it takes longer than 30 minutes to achieve an orgasm and ejaculate). While these conditions can be stressful, they don't have to interfere with a man's sex life, as there are many ways to manage them. Strategies include sex therapy, testosterone therapy, medication, changing sexual positions, using sex devices, and managing alcohol intake.

A 2023 study suggests that toothbrushing twice daily can lower rates of hospital-acquired pneumonia in seriously ill hospitalized patients.

With climate change, rising temperatures are making many regions dry within the US and beyond. The effects of droughts on the planet and our health are complex, and include water shortages, higher risk of disease, changes in habitability, and worse air quality.

The first over-the-counter daily birth control pill was approved by the FDA in 2023. How effective is it?

Here are answers to these and other questions about this new nonprescription contraceptive.

Minimally invasive surgery to remove the prostate gland is generally very well tolerated, but there can be complications, as in the case of Defense Secretary Lloyd Austin earlier this year. A Harvard-affiliated urologist answers questions about the possibility of such complications.

Uterine fibroids affect up to 80% of women by age 50. These noncancerous growths can shrink as menopause approaches and the body's estrogen level falls. But for some women, fibroids grow during and after the transition to menopause, worsening symptoms such as heavy bleeding, pelvic or lower back pain, bloating, frequent urination, or painful sex. Treatments for other health conditions may also influence older women's fibroid symptoms. To avert cancer concerns, doctors may remove fibroids that grow noticeably after menopause.

A 2023 study found that patients in intensive care units (ICUs) were less likely to die and spent less time on a ventilator during their stay when their teeth were brushed twice daily. Toothbrushing appears to protect patients from pneumonia, the most common ICU-acquired infection.
