Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term poor airflow. The main symptoms include shortness of breath and cough with sputum production. COPD typically worsens over time.1 Eventually walking up stairs or carrying things will be difficult.2 Chronic bronchitis and emphysema are older terms used for different types of COPD.23 The term "chronic bronchitis" is still used to define a productive cough that is present for at least three months each year for two years.4
Tobacco smoking is the most common cause of COPD, with a number of other factors such as air pollution and genetics playing a smaller role.5 In the developing world, one of the common sources of air pollution is poorly vented heating and cooking fires.2 Long-term exposure to these irritants causes an inflammatory response in the lungs resulting in narrowing of the small airways and breakdown of lung tissue.6 The diagnosis is based on poor airflow as measured by lung function tests.7 In contrast to asthma, the airflow reduction does not improve much with the use of a bronchodilator.2
Most cases of COPD can be prevented by reducing exposure to risk factors.8 This includes decreasing rates of smoking and improving indoor and outdoor air quality. While treatment can slow worsening, there is no cure.2 COPD treatments include stopping smoking, vaccinations, respiratory rehabilitation, and often inhaled bronchodilators and steroids.

A basketball term where a team simply misses a ton of shots. This can be because the team is actually bad at shooting or because they are in a random shooting slump. PSD is not usually a terminal. Symptoms will start to wane and the team will eventually be healed. Their shooting averages will revert to normal. If the team is just bad at shooting basketballs, they will die a slow and painful death in the form of lost games due to PSD.

Baller 1: Man, how do we keep losing these games? These teams are terrible.
Baller 2: I don't know man, I think it's a bad case of Poor Shooting Disease (PSD).

when a White man who is part of a larger group which includes minorities and/or women, feels that he must share “his” (often unsolicited, typically incorrect) knowledge and/or experience as it pertains to a discussion not involving him.
Bill is married to a Karen, he suffers from White Man In The Room Disease. He feels that he should be the authority on a particular subject in the group, simply because he’s White.

Any virus or bug that infects your computer due to having too many friends on your social networking site that don't run the proper security software on either their site or their computer.
I caught a nasty SND (Social Networking Disease) on Facebook the other day and had to reconfigure my entire system.
