Study Shows That Bariatric Surgery Reduced COPD Exacerbations by More Than Half
I often tell my patients with COPD that quitting smoking can have a greater effect on their respiratory health than any inhaler that I could prescribe them. Should I now also extend that advice to include weight loss for obese patients with COPD? In this journal CHEST® study, researchers used registry data to look at COPD exacerbations for patients both before and after bariatric surgery. In the year before bariatric surgery, risk of COPD exacerbations was 31%. Looking at the rate of COPD exacerbations during the year after bariatric surgery, that rate dropped to 12%, an astounding change.
The accompanying editorial proposes mechanisms explaining why this might be so and postulates whether obesity could be a modifiable risk factor in COPD. While these results are certainly exciting, we look forward to future investigation into whether bariatric surgery, or other weight loss means, could further help reduce risk of COPD exacerbation.
Pneumonia: If You Can’t See It, Does It Still Exist?
The diagnosis of pneumonia requires the radiographic presence of infiltrates on imaging. However, with its greater resolution, CT scanning can often demonstrate infiltrates when none are seen on chest roentgenogram. Do we treat these the same as a regular pneumonia? This study sought to quantify differences between patients with pneumonia as seen on a chest radiograph vs CT scanning. The differences between the two groups appeared to be minor, with procalcitonin levels appearing to be lower in the CT group. Otherwise, it would appear that patients with pneumonia seen only on CT scanning should be managed like other groups.
I enjoy fielding questions from patients. Yes, I sense you’re rolling your eyes, but really, anything that I can answer that helps keep them out of the hospital is, I feel, time well spent. Recently though, I’ve been fielding a number of questions that have me concerned. These questions often have a leading tenor about them like, “are you using stem cells for COPD yet?” The questions imply that stem cells are the de rigeur treatment for COPD. Now I may not be at the leading edge of any fashion, but being unfashionable in my treatment regimens? Never!
I can’t blame anyone for wanting to seek out treatments for COPD. It is after all, a leading cause of death and illness in the U.S. And it’s widely regarded that the changes caused by COPD/emphysema in the lungs are permanent. While there are now several different treatment options for emphysema/COPD, very few can prolong life. So if I had a family member with emphysema, I might naturally seek out treatments for COPD that go beyond the usual treatments, and with all the hype surrounding stem cells, why not take a look?
What people find when they google “stem cells and COPD” is in a word, distressing. It’s a fantasy world full of promises of health, healing, and better breathing. Equally distressing are the things that people who visit these sites aren’t recognizing: the greed, lies, lack of ethics, illusions, and misleading claims.

Press Release: Annual Conference of the Universal College of Chest Physicians October 2085; New Chicago, Mars.
The annual conference enjoyed another record attendance today as attendees flocked to Dr. Ramachandran III’rds keynote address reviewing exploits of physicians in the early part of the century. Dr. Ramachandran highlighted some key decisions and their consequences, such as the ACGME’s decree in 2032 that all residents should be swaddled before their scheduled hourly nap times. This of course led to the now infamous Great Hospital Apocalypses of 2033, 2034, and 2035.
Perhaps nearly as intriguing was the plight of inhaled corticosteroids for the treatment of respiratory diseases like asthma and COPD in the beginning of the 21st century. The period began with greater awareness and concern regarding the use of long acting beta agonist (LABA) bronchodilators such salmeterol. That risk was highlighted by findings published in the SMART trial (access through Chest archives here). There was increased concern regarding the potential harm caused by LABA which culminated in the placement of warnings on medications which contained LABA bronchodilators. These medications, experts said, were to be prescribed with extreme caution because of the possible increase in harm, particularly among children.
Scholars of the early 21st century thus highly recommended that asthmatics, especially children, be started on steroid inhalers before having to resort to using inhaled LABAs. Many also theorized that inhaled steroids had a protective effect when combined with LABA’s, possibly ameliorating their potential danger. Thus many at the time recommended a strategy of not using LABA inhalers at all, unless also simultaneously prescribing an inhaled steroid.
However, problems with this approach started to appear late in the first decade of the century. The TORCH study, a trial using combined inhaled LABA/inhaled steroids in adults with COPD suggested that there was an increased incidence of pneumonia among those treated with inhaled steroids. Early in the second decade a pivotal study then demonstrated that asthmatic children treated with inhaled steroids ended up being about half an inch shorter than they might have otherwise been (interestingly, a later study in 2035 correlated the reduced height with a statistically significant decrease in NBA dunking).

Life can change in a heartbeat. Most of us believe that our lives, our loves and all the that things that make us who we are is a gift from a higher power. One that can be taken away as swiftly as it is given. But somewhere in the shuffle of taking kids to practice, catching up on emails, worrying about bills, and the search for the perfect barbecue, it’s all too easy to forget the truth of life. The one truth. The one single thing that life guarantees each and every one of us. From the moment we take our first breath, life makes to us but one promise. The promise that our life will someday end.
“Who do you think you are?”
For some of us, death comes after a lifetime of achievement, for others all too soon. For many it will be feared, for others it will be welcomed as their bodies wither away. But for more and more of us in our increasingly sterile and safe society, it is simply not to be thought of at all. An unwelcome stepchild locked tightly away in the attics of our consciousness. Like a demon in waiting, we reshape it, remake it, remold it, until it becomes an ever distant sunset that bookends a romantic dream of a life full of love, accomplishment, achievement.
“You have no right to say that!”
Until finally, that inevitable day approaches. A man or woman in a white coat tells you the terrible news that your loved one is passing away. That yes, they are alive and can be kept alive, but there is practically no chance that they could recover. They will never go back to the person they were before.
Health-care technology advocates have long been preaching about the potential of smartphones and other types of disruptive technology to improve health-care delivery. We in organized medicine have been slow to answer the call. Studies that showcase the ability of these tools in major medical journals are rare. However, in a recent issue of CHEST, we see a welcome addition to the medical literature.
In this study, researchers taught patients with COPD to create daily symptom diaries on smartphones (BlackBerry 8700s). The results were uploaded to a research server and the program alerted staff when certain predetermined criteria were met. Using the data, researchers were able to accurately and quickly identify patients who were having an exacerbation of their COPD. They were also able to collect data on both the timing and length of the exacerbation.
This has exciting implications. Perhaps this kind of patient centered data could be used to identify patients with severe symptoms and prevent hospitalizations, or to serve as a measure of response in clinical trials to various interterventions. The possible applications are numerous.
Though there is one aspect of this study that, as a tech geek, leaves me ambivalent. Should I be excited that even an obsolete smartphone could prove to be so useful? Or depressed that even an obsolete smartphone is so far ahead of current medical technology?
