The trends of COPD mortality and prevalence over the past 2 decades across all provinces remain unknown in China. We used data from the Global Burden of Disease Study 2013 (GBD 2013) to estimate the mortality and prevalence of COPD during 1990 to 2013 at a provincial level. ⋯ COPD remains a huge health burden in many western provinces in China. The substantial increase in COPD cases represents an ongoing challenge given the rapidly aging Chinese population. A targeted control and prevention strategy should be developed at a provincial level to reduce the burden caused by COPD.

Although 28% to 49% of severe sepsis hospitalizations have been described as being "culture negative," there are very limited data on the epidemiology and outcomes of those with culture-negative severe sepsis (CNSS). The objectives of this study were to investigate the proportion and trends of CNSS and its association with mortality. ⋯ CNSS among hospitalized patients is common, and its proportion is on the rise. CNSS is associated with greater acute organ dysfunction and mortality. Having CNSS is an independent predictor of death.

The use of antipsychotic agents has been associated with increased pneumonia risk, but although people with dementia are particularly susceptible to pneumonia, only one small study has assessed the risk of pneumonia in relation to the use of antipsychotic agents among people with Alzheimer disease (AD). ⋯ Regardless of applied study design, treatment duration, or the choice of drug, the use of antipsychotic agents was associated with a higher risk of pneumonia. With observational data, we cannot fully rule out a shared causality between pneumonia and the use of antipsychotic agents, but the risk to benefit balance should be considered when antipsychotic agents are prescribed.

Case Reports
A Man in His 20s With Diffuse Lung Opacities and Acute Respiratory Failure After Hookah Smoking.
A man in his 20s with no medical history presented with 2 days of progressively worsening shortness of breath accompanied by subjective fevers, chills, body aches, decreased appetite, night sweats, and cough producing nonbloody sputum. He denied childhood lung diseases, allergies, or a family history of lung disease. ⋯ He denied travel outside of the northeastern United States. He did not take medications, use illicit drugs, or engage in high-risk behavior.

Although endobronchial coils for the treatment of severe emphysema are associated with an acceptable safety profile, adverse events such as pneumothorax and thoracic pain may occur. The coils are indicated as a permanent implant and are deemed very difficult to remove. We describe the first successful removal of two coils 10 months after placement in a patient who experienced persistent thoracic pain. This case report highlights that very distal (subpleural) coil placement may induce pneumothorax and subsequent thoracic pain and that nonsurgical removal of coils up to 10 months after implantation is feasible.
