Despite accumulating evidence about its adverse health effects, water-pipe tobacco smoking has become very popular among youth. The aim of this study was to compare smoke exposure and the kinetics of exhaled carbon monoxide (eCO) between water-pipe and cigarette smokers under different conditions. ⋯ Our results suggest that water-pipe smoking is associated with significantly higher toxicant exposure than cigarette smoking even in outdoor environments. Furthermore, even passive, indoor water-pipe smoke exposure may have significant health hazards compared with those of active cigarette smoking.

Observational Study
Non-Malignant Pleural Effusions (NMPE): a prospective study of 356 consecutive unselected patients.
Pleural effusion secondary to a nonmalignant cause can represent significant morbidity and mortality. Nonmalignant pleural effusion (NMPE) is common, with congestive heart failure representing the leading cause. Despite this, there are limited data on mortality risk and associated prognostic factors. ⋯ This is the largest prospectively collected series in patients with NMPE, demonstrating that cases secondary to organ dysfunction have extremely high 1-year mortality. In addition, the presence of bilateral and transudative effusions is an indicator of increased mortality. Clinicians should be aware of these poor prognostic features and guide management accordingly.

Resident loved ones of patients with COPD can play an important role in helping these patients engage in physical activity. We aimed to compare activity levels and exercise motivation between patients with COPD and their resident loved ones; to compare the same outcome measures in patients after stratification for the physical activity level of the loved ones; and to predict the likelihood of being physically active in patients with a physically active resident loved one. ⋯ Patients with COPD are more physically inactive and sedentary than their loved ones, despite relatively similar exercise motivation. Nevertheless, patients with an active loved one are more active themselves and have a higher likelihood of being active.

Case Reports
A Woman in Her 30s With a History of Cervical Cancer Presents With Shortness of Breath and Pleuritic Chest Pain.
A woman in her 30s presented to the ED with a 3-month history of shortness of breath on exertion, dry cough, and pleuritic chest pain. A month ago, the patient was seen at an internal medicine clinic and was found to have a right pleural effusion. A thoracentesis revealed straw-colored fluid, a total nucleated cell count of 1,260 × 106/L, and a differential with neutrophils of 0.15, lymphocytes of 0.55, macrophages/monocytes of 0.19, and eosinophils of 0.10. ⋯ A CT scan of the chest, abdomen, and pelvis was negative for distant metastases. The patient completed treatment with external beam radiation therapy and cisplatin chemotherapy 6 months ago. Three weeks prior to presentation to the ED, a repeat MRI pelvis showed no evidence of tumor progression and features consistent with posttreatment fibrotic changes.
