Long non-coding RNAs (lncRNAs) functioning as competing endogenous RNAs (ceRNAs) play critical roles in tumour progression. However, prognosis-related ceRNA networks in lung adenocarcinoma (LUAD) have not been well characterised. ⋯ This ceRNA network contributes to understanding the pathogenesis of LUAD. Furthermore, the molecules in the network are valuable predictive factors for LUAD prognosis as well as potential therapeutic biomarkers.

Aortic stenosis (AS) is considered severe when the aortic valve area (AVA) is < 1.0 cm2 and the mean aortic valve gradient (mAVG) exceeds 40 mm Hg. Since many patients with AVA < 1.0 cm2 do not manifest an mAVG > 40 mm Hg, we sought to determine the AVA at which mAVG tends to exceed 40 mm Hg in a sample of subjects with varied transvalvular flow rates. ⋯ Subjects with AVA of 0.8 and 0.9 cm2 rarely had mAVG > 40 mm Hg, even when the transvalvular flow rate was normal. Using current guidelines, it is not clear if such cases should be classified as severe.

The objective of this study was to estimate the safety profile of pulmonary hypertension-specific therapies using placebo-controlled and active comparator trials. ⋯ About half of the main categories and subcategories of adverse reactions according to MedRA were associated with a relatively high frequency and hazard ratio. Their risk can be increased when combination regimens are used, especially.

Our goal was to systematically review the current evidence comparing the relative effectiveness of two maxillary sinus floor elevation (MSFE) approaches (internal and external) without bone grafts with that of conventional/grafted MSFE in patients undergoing implantation in the posterior maxilla. ⋯ This systematic review revealed that both non-graft and grafted MSFE had high implant survival rates. Owing to the moderate strength of the evidence and short-term follow-up, the results should be interpreted with caution.

Association of the MMP-3, MMP-9 and MMP-12 gene polymorphisms with COPD risk: a meta-analysis.
Given the evidence that the matrix metalloproteinases (MMPs) play an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD), a number of case-control studies have attempted to assess the relationship between genetic polymorphisms in MMP genes and COPD risk. However, reliable measures of these results are lacking. ⋯ The findings of this meta-analysis suggest that there is a risk of COPD associated with the MMP-9 rs3918242 and MMP-12 rs2276109 polymorphisms in certain ethnic groups.
