Previously selected articles that were thought important but had received little attention were summarized under our “News” section. However, the work of publication (review, DOAJ, doi, social media, etc.) has become too arduous to do justice to these publications. Therefore, we are beginning a new section titled “News from Other Journals” where selected articles are briefly summarized. Important articles that are published in journals commonly read by pulmonologists, intensivists or sleep physicians will not necessarily be reviewed but articles that are in general medicine journals or lower impact journals that might be of interest to the practicing physician are selected. As always, there will be links to the article via CrossRef and/or PubMed.

The Importance of Smoking Cessation on Surgical Outcome in Primary Lung Cancer

Fukui M, Suzuki K, Matsunaga T, Oh S, Takamochi K. Ann Thorac Surg. 2019 Jan 2. pii: S0003-4975(18)31871-X. [CrossRef] [PubMed] 

Smoking cessation is important in the management of patients who require pulmonary resection. However, the impact of short-term smoking cessation on the surgical outcome remains unclear. The authors conducted a retrospective study was conducted on patients with stage I-III primary lung cancer who underwent resection between 2012 and 2016. The rate of surgical mortality and morbidity were evaluated according to smoking status. The relationship between the preoperative interval of smoking cessation and pulmonary complications after surgery was also examined. The study included 666 patients, of which 256 (38.4%) were never smokers and 410 (61.6%) were smokers. There were significant differences between the smokers and never smokers regarding the 90-day mortality rate (2.0% vs 0%, p=0.025), and respiratory complications (22.3% vs 3.5%, p<0.001). A multivariate analysis indicated that smoking (OR 2.8, p = 0.017), FEV 1.0/ FVC < 0.7 (OR 2.6, p = 0.001), %DLCO < 40% (OR 4.2, p =<0.001), and clinical stage of lung cancer (OR 2.3, p = 0.005) were predictors of pulmonary complications after pulmonary resection. In comparison to never smokers, the odds ratios for pulmonary complications at each cessation interval (Current smoker/ cessation for -1month/ 1-3 months/ 3-6 months/ 6-12 months/ > 12 months) were 12.9 (p < 0.001)/ 10.3 (p < 0.001)/ 8.5 (p < 0.001)/ 6.3 (p=0.011)/ 6.0 (p = 0.003)/ 5.0 (p < 0.001). A longer period of cessation might be more effective for reducing the risk of pulmonary complications, however, even short-term smoking cessation is beneficial prior to thoracotomy for lung cancer.

FDA Warns About Increased Risk of Ruptures or Tears in the Aorta Blood Vessel With Fluoroquinolone Antibiotics in Certain Patients

US Food and Drug Administration. December 20, 2018. Available at: https://www.fda.gov/Drugs/DrugSafety/ucm628753.htm (accessed 12/22/18).

A U.S. Food and Drug Administration (FDA) review found that fluoroquinolones can increase the occurrence of aortic aneurysm dissection or rupture. Cases and four published observational studies showed an increased risk of aortic aneurysm or dissection associated with fluoroquinolone use. The FDA advises prescribing fluoroquinolone antibiotics to patients who have an aortic aneurysm or are at risk for an aortic aneurysm, such as patients with peripheral atherosclerotic vascular diseases, hypertension, certain genetic conditions such as Marfan syndrome and Ehlers-Danlos syndrome, and elderly patients unless no other alternatives are available. The reports are not surprising since fluoroquinolones have been associated tendon inflammation and even rupture. Azithromycin and doxycycline have also rarely been reported to cause tendonitis and rupture but it is unclear whether caution should be used with these antibiotics in patients at risk for aortic dissection or rupture.

Optimizing Home Oxygen Therapy. An Official American Thoracic Society Workshop Report

Jacobs SS, Lederer DJ, Garvey CM, et al. Ann Am Thorac Soc. 2018 Dec;15(12):1369-81. [CrossRef] [PubMed]

The system of delivering supplemental oxygen to the more than 1.5 million people in the U.S. who rely on it is broken concluded a convened at the ATS International Conference in 2017. The panel unanimously found that the implementation of competitive bidding for durable medical equipment, including home oxygen, nearly a decade ago by the Centers for Medicare and Medicaid Services (CMS) has led to the crisis. A 2017 survey of nearly 2,000 supplemental oxygen users, conducted by the ATS Nursing Assembly, addressed some specific issues related to home oxygen delivery. The survey found that half of all respondents reported problems with their oxygen, including equipment malfunction, and being too heavy to manage physically and lack of portability, especially when traveling. Also, 70% reported having no more than 4 hours of portable oxygen, while 81% said they required more than 5 hours' supply. Beginning Jan. 1, 2019, CMS will suspend the durable medical equipment competitive bidding program for 2 years to assess it, but it is not clear what this means for liquid oxygen and other supplemental oxygen availability.

FDA Approves First Treatment for Lambert-Eaton Myasthenic Syndrome, A Rare Autoimmune Disorder

FDA News Release. November 28, 2018. Available at: https://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm627093.htm (accessed 12/4/18).

The US Food and Drug Administration (FDA) has approved amifampridine (Firdapse) tablets as the first ever treatment of the rare autoimmune disorder Lambert-Eaton myasthenic syndrome (LEMS) in adults (1).

In LEMS, the immune system attacks the neuromuscular junction and disrupts the ability of nerve cells to send signals to muscle cells. LEMS may be associated with other autoimmune diseases, but more commonly occurs in patients with cancer such as small cell lung cancer, where its onset precedes or coincides with the diagnosis of cancer. The prevalence of LEMS is estimated to be three per million individuals worldwide.

The efficacy of amifampridine was studied in a pair of clinical trials involved 64 adult patients administered either amifampridine or placebo. Using the 13-item, physician-rated categorial Quantitative Myasthenia Gravis scale to assess for muscle weakness, as well as the seven-point, patient-rated Subject Global Impression, investigators assessed the therapy’s benefit for LEMS’ most prevalent symptoms. For both measures, patients treated with amifampridine reported greater benefits than those administered placebo.

In a statement included with the announced approval, Billy Dunn, MD, director of the Division of Neurology Products in the FDA’S Center for Drug Evaluation and Research, noted the burdens faced by the 3 million-patient population. “There has been a long-standing need for a treatment for this rare disorder,” Dunn said. “Patients with LEMS have significant weakness and fatigue that can often cause great difficulties with daily activities.”

The most common side effects experienced by patients in the clinical trials were burning or prickling sensation (paresthesia), upper respiratory tract infection, abdominal pain, nausea, diarrhea, headache, elevated liver enzymes, back pain, hypertension and muscle spasms. Seizures have been observed in patients without a history of seizures. Because it affects voltage-gated ion channels, it is contraindicated in people with long QT syndrome and in people taking a drug that might prolong QT like sultopride, disopyramide, cisapride, domperidone, rifampicin or ketoconazole. It is also contraindicated in people with epilepsy or badly controlled asthma.

Does Point-of-Care Ultrasonography Improve Clinical Outcomes in Emergency Department Patients with Undifferentiated Hypotension?

Atkinson PR, Milne J, Diegelmann L, et al. Ann Emerg Med. 2018 Oct;72(4):478-89. [CrossRef] [PubMed]

Point-of-care ultrasonography protocols are commonly used in the initial management of patients with undifferentiated hypotension in the emergency department (ED) or the intensive care unit (ICU). However, there is little published evidence for any mortality benefit. The authors compared a point-of-care ultrasonography protocol versus standard care without point-of-care ultrasonography for survival and clinical outcomes. Follow-up was completed for 270 of 273 patients. The most common diagnosis in more than half the patients was occult sepsis. No important differences between the two groups for 30-day survival. There were no important differences in rates of computed tomography (CT) scanning, inotrope or intravenous fluid use, and ICU or total length of stay. The authors conclude that addition of a point-of-care ultrasonography protocol to standard care may not translate into benefits in survival, length of stay, rates of CT scanning, inotrope use, or fluid administration.
