Circular RNAs (circRNAs) belong to a family of covalently closed single-stranded RNAs that have been implicated in cancer progression. Previous studies have reported that hsa_circ_0087784 was abnormally expressed in breast cancer. However, the role of hsa_circ_0087784 in non-small cell lung cancer (NSCLC) is unknown. ⋯ Our findings suggested that downregulation of hsa_circ_0087784 inhibited NSCLC metastasis and progression through the regulation of CDCA4 expression and miR-576-5psponging.

Although cystic fibrosis (CF) is widely considered a lung disease, the prevalence of CF-specific gastrointestinal symptoms and diseases has continued to rise. Peptic ulcer disease (PUD) has not been well-studied among people with CF (PwCF) and may be a common cause of abdominal symptoms. In PwCF, impaired bicarbonate secretion and unbuffered gastric acid production have been attributed to the development of ulcers, although ulcers remain uncommon. The objective of this study was to evaluate the prevalence of PUD in PwCF and assess for possible contributing factors. ⋯ Although cystic fibrosis has been historically known as a disease of childhood, advancements in therapy have led to prolonged life expectancy and higher prevalence for cystic fibrosis-related digestive diseases. This study revealed a low prevalence of PUD in PwCF. Hispanics and those with NASH are more likely to develop peptic ulcers.

Cisplatin-based chemoresistance is major obstacle for breast cancer (BC) including Triple-negative breast cancer (TNBC). SIRT7 is reportedly involved in the progression of BC, the underlining mechanism in Cisplatin-based chemoresistance in BC remains unclear. This work is to elucidate effects of SIRT7 on cisplatin resistance in breast cancer regulated by miR-152-3p. ⋯ Inhibition of SIRT7 by miR-152-3p may be a promising strategy against the resistance to cisplatin-based chemotherapy in BC containing TNBC.

Current guidelines lack clarity about the optimal duration of octreotide therapy for patients with esophageal variceal hemorrhage (EVH). To address this lack of evidence, we conducted a randomized clinical trial (RCT) of 24-hr versus 72-hr continuous infusion of octreotide for patients with EVH. ⋯ A 24-hr infusion is non-inferior to a 72-hr infusion of octreotide for prevention of re-bleeding in patients with EVH. We propose that shortened octreotide duration may help reduce hospital stay and related costs in these patients.

Interstitial lung disease (ILD) represents a heterogeneous group of disorders characterized by inflammation and fibrosis of the pulmonary interstitium. Risk factors for ILD include various environmental exposures and identifying specific exposures offers a point of intervention for preventing disease. ⋯ While this report does not attempt to establish causality, we hypothesize that exposure to the industrial solvent tetrachloroethylene may serve as a contributing factor given its links to epithelial injury, inflammation, redox imbalance and apoptosis. We hope that this report serves to not only inform readers of this possible connection between dry cleaning and ILD but also lay the foundation for additional studies examining the effects of tetrachloroethylene on the lung.
