The role of transforming growth factor β1 (TGF-β1) and tumor necrosis factor α (TNF-α) in asthma is unclear. The aim of this study was to assess the relationships among polymorphisms, clinical phenotypes, and the serum levels of TGF-β1 and TNF-α. ⋯ The genetic polymorphisms of TGF-β1 and TNF-α are associated with asthma. TGF-β1 modulates atopy. Both TGF-β1 and TNF-α modulate clinical severity and airway obstruction, in an additive manner.

Primary malignant fibrous histiocytoma (MFH) of the lung is a very rare neoplasm that usually presents as a parenchymal mass. Here we report an unusual case of primary MFH of the bronchus, showing relatively benign clinical features. ⋯ There is a possibility that endobronchial MFH has a more favorable prognosis than MFH of other origins. If this is true, interventional bronchoscopy can be a reasonable option for non-operable cases of MFH.

Meta Analysis
The comparison of CPAP and oral appliances in treatment of patients with OSA: a systematic review and meta-analysis.
A systematic review and meta-analysis was performed to compare the outcomes of oral appliances (OAs) with those of CPAP in treatment of patients with obstructive sleep apnea (OSA). ⋯ CPAP yielded better polysomnography outcomes, especially in reducing AHI, than OAs, indicating that OAs were less effective than CPAP in improving sleep-disordered breathing. However, similar results from OAs and CPAP in terms of clinical and other related outcomes were found, suggesting that it would appear proper to offer OAs to patients who are unable or unwilling to persist with CPAP.
