Discussions focused on how the agenda can support better alignment of priorities, reinforce capacity, and enhance the systematic use of evidence in policy decisions.

What’s the Bottom Line? What do we know about the effectiveness of complementary health approaches for low-back pain? • Research of low- to moderate-quality suggests that several mind and body practices—including acupuncture, electromyography (EMG) biofeedback, low-level laser therapy, mindfulness-based stress reduction, progressive muscle relaxation, spinal manipulation, tai chi, and yoga—may provide benefit for people with chronic low-back pain. • For acute low-back pain, low-quality evidence

When Something Moves Out of Position Your body is designed so that every organ and tissue stays securely in place. Layers of muscle and connective tissue act as support walls, holding everything where it belongs. However, if these supportive structures become weak or damaged, they may no longer be able to do their job effectively. When that happens, part of an organ or tissue can push through an opening or weak spot in the surrounding muscle. This condition is known as a hernia. Hernias most

Scientists at the University of Gothenburg have analyzed carbon dioxide and oxygen concentrations in 23 mangrove regions around the globe. Their findings warn that these ecosystems are facing growing pressure as ocean temperatures continue to climb. Water conditions in mangroves shift continuously

How Microorganisms in Your Mouth Influence Your Health Your mouth is more than just teeth, gums, and a tongue. It is also home to billions of microscopic organisms that can only be seen under a microscope. These include bacteria, fungi, and viruses. Collectively, the community of microorganisms living in your mouth is called the oral microbiome. Researchers believe the oral microbiome may play a role in diseases that affect not only the mouth but also other parts of the body. Studying these
