With the advancement of cardiorespiratory interventions, the survival rate among patients with Duchenne muscular dystrophy (DMD) has increased. Subsequently, pneumothorax has become a significant problem in patients with prolonged ventilatory support. ⋯ On pneumothorax occurrence in patients with DMD, recurrences and severe lung damage are common; moreover, these patients show higher mortality rates than patients without pneumothorax. Chest CT scans should be performed to identify risk factors, and treatment should be initiated accordingly. In addition, physicians should consider chest CT scanning in the case of suspected pneumothorax, even if no radiographic abnormality is found.

Aberrations in the coagulation system have been implicated in the pathogenesis of interstitial lung disease (ILD). Anticoagulants have been proposed as a potential therapy in ILD; however, a randomized controlled trial examining warfarin as a treatment for IPF was terminated early due to increased death rates. This has led some to speculate that warfarin specifically may be harmful in ILD, and use of direct oral anticoagulants (DOACs) could result in superior outcomes. ⋯ The need for anticoagulation is associated with an increased risk for death or transplant in patients with ILD, in both the IPF and non-IPF population. Further research is required to determine if warfarin and DOACs present varying safety profiles in patients with ILD.

In the United States, COPD is a leading cause of mortality, with a substantial societal health and economic burden. With anticipated population growth, it is important for various stakeholders to have an estimate for the projected burden of disease. ⋯ This study projects the substantial burden of COPD that the American society is expected to incur with current patterns for treatments and smoking rates. Mitigating such burden requires targeted budget appropriations and cost-effective interventions.

The impact of ECG presentations of acute myocardial infarction (AMI) in cardiogenic shock is unknown. ⋯ In patients with cardiogenic shock, NSTEMI and LBBBMI presentations reflect higher-risk profiles than STEMI presentations, but are not independent risk factors of mortality. ECG presentations did not modify the treatment effect, supporting culprit-lesion-only percutaneous coronary intervention as the preferred strategy across the AMI spectrum.

A 51-year-old woman with a history of diabetes mellitus and anemia sought treatment at the emergency room for a 2-month history of dry cough and shortness of breath and a 1-week history of substernal chest tightness. One month before her presentation, she was seen at a separate hospital for dyspnea and was found to be anemic. She underwent chest radiography and CT scanning of the chest that was unrevealing to the cause of dyspnea. ⋯ Medications included an oral diabetic medication. She had no significant family history. She never smoked and had no history of illicit drug or alcohol use.
