Earlier this year, NIH Director Francis S. Collins, M.D., Ph.D., met with research and development leaders from the world’s leading biopharmaceutical companies to discuss the opioid crisis. The meeting highlighted new ways for government and private industry to work together to address the opioid crisis and find better ways to manage pain.

Fall 2017 medlineplus.gov/magazine 17 Breathtaking Managing a COPD Diagnosis

Chronic obstructive pulmonary disease (COPD) is a serious lung disease that makes it hard to breathe. It’s also known as emphysema or chronic bronchitis.

In people who have COPD, the airways—tubes that carry air in and out of your lungs—are partially blocked. This makes it hard for air to get in and out. COPD causes symptoms such as coughing, mucus, wheezing, shortness of breath, and chest tightness. These symptoms tend to worsen over time. Severe COPD may prevent you from doing even basic activities like walking, cooking, or taking care of yourself. Cigarette smoking is the leading cause of COPD. However, up to 25 percent of people with COPD never smoked. Exposure to other lung irritants— such as air pollution, chemical fumes, or dust—may contribute to COPD. A rare genetic condition called alpha-1 antitrypsin deficiency can also cause the disease—but it is rare. Most of the time, COPD affects middle-aged or older adults. Some COPD patients wait to seek help as symptoms such as increased shortness of breath may seem like a natural part of aging. If you are or a loved one suspects that you have COPD symptoms, make sure to see a health care provider. There is no cure and doctors do not know how to reverse the damage to the lungs. But treatments and lifestyle changes can help patients feel better, stay active, and slow the progression of the disease.

What is pulmonary rehabilitation and why is it important for COPD patients? Pulmonary rehabilitation is a treatment for patients with chronic lung diseases like COPD. It provides patients with exercise, education, and support. The primary goal is to help patients achieve their maximum level of independence and functioning. It benefits exercise tolerance, symptoms, and quality of life, with a reduction in the use of health care resources. Pulmonary rehabilitation involves a long-term commitment from the patient and a team of health care providers. The team may include respiratory therapists, physical and occupational therapists, dietitians or nutritionists, and psychologists or social workers.

Predicting Autism in High-Risk Infants AN NIH-SUPPORTED STUDY has found a tool that may be able to predict which high-risk, 6-month-old infants will develop autism spectrum disorder by age 2. Such a tool would be significant because it could lead to earlier treatment of the condition. Researchers looked at how regions of the brain work together during different tasks and during rest. The study used scanning technology called Study researchers looked at how regions of the brain work together. functional magnetic resonance imaging (functional MRI or fMRI). It measures “Although the findings are early- Another study analysis that tested brain activity by looking at changes in stage, the study suggests that in the how well the results could apply to blood flow. future, neuroimaging may be a useful other cases had an accuracy rate of The study is funded by NIH’s Eunice tool to diagnose autism or help health 93 percent.
