Randomized Controlled Trial Multicenter Study
Association of migraine with asthma risk: A retrospective population-based cohort study.
Both migraine and asthma are common health problems in the general population. However, the association between these two disorders is yet to be fully explored. ⋯ Adult patients with migraine are at a higher future risk of asthma development.

Review Case Reports
Organizing pneumonia related to electronic cigarette use: A case report and review of literature.
Electronic cigarettes (e cigarettes) are battery operated devices that produce aerosol by heating a solution typically made up of nicotine, propylene glycol, glycerin and flavouring agents. The use of e cigarettes has risen dramatically in recent years especially among adolescents and young adults. These devices have been marketed as safer alternatives to tobacco smoking by their manufactures despite lack of adequate safety data. ⋯ As the current data on health effects of e cigarettes is limited, case reports can serve important piece of information in this regard. The use of e cigarettes has increased exponentially in recent years and continue to rise; therefore, physicians should be aware of adverse effects and toxicity related to its use.

Randomized Controlled Trial
One minute sit-to-stand test is an alternative to 6MWT to measure functional exercise performance in COPD patients.
Chronic obstructive pulmonary disease (COPD) is frequently associated with a reduced functional exercise performance. Even if this parameter is routinely evaluated using 6-minute walking test (6MWT), new field tests are regularly investigated as alternative tests. The aim of this study was to compare functional exercise performance evaluation by sit-to-stand test (STST) and 6MWT and to evaluate reliability and repeatability of the STST in COPD patients. ⋯ The one minute sit-to-stand test is a valuable alternative to 6MWT to estimate functional exercise performance in COPD patients. The cardiorespiratory demand is different between both tests although the variation of dypsnea is similar. No learning effect was observed for STST.

Transthoracic echocardiography (TTE) and computerized axial tomography (CT) are complementary imaging techniques. It is possible that a combination of the two may offer a better way of identifying pulmonary hypertension (PH) than either one alone. ⋯ The combination of TTE and chest CT is better than either imaging technique alone in identifying patients with PH in a heterogeneous population and may exclude PH.

To explore the diagnostic value of joint detection of soluble B7-H4 (sB7-H4) and carcinoembryonic antigen (CEA) in identifying malignant pleural effusion (MPE) from benign pleural effusion (BPE). ⋯ sB7-H4 was a potentially valuable tumor marker in the differentiation between BPE and MPE. The combined detection of sB7-H4 and CEA could improve the diagnostic sensitivity and specificity for MPE.
