INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18189570. [PMID: 34574495 PMCID: PMC8464975 DOI: 10.3390/ijerph18189570] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 09/05/2021] [Accepted: 09/07/2021] [Indexed: 12/29/2022]
Abstract
Decisions in the management and rescue of avalanche victims are complex and must be made in difficult, sometimes dangerous, environments. Our goal was to identify indicators for quality measurement in the management and rescue of avalanche victims. The International Commission for Mountain Emergency Medicine (ICAR MedCom) convened a group of internal and external experts. We used brainstorming and a five-round modified nominal group technique to identify the most relevant quality indicators (QIs) according to the National Quality Forum Measure Evaluation Criteria. Using a consensus process, we identified a set of 23 QIs to measure the quality of the management and rescue of avalanche victims. These QIs may be a valuable tool for continuous quality improvement. They allow objective feedback to rescuers regarding clinical performance and identify areas that should be the foci of further quality improvement efforts in avalanche rescue.

NUCLEIC ACIDS 2020; 22:846-861. [PMID: 33230480 PMCID: PMC7658493 DOI: 10.1016/j.omtn.2020.09.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Accepted: 09/11/2020] [Indexed: 11/25/2022]
Abstract
Recent studies have suggested that microRNA let-7i is a tumor suppressor in human cancers, including esophageal cancer, but its underlying mechanism is not yet fully understood. We investigated the role and mechanisms of let-7i in the progression of esophageal cancer. We first showed that let-7i was downregulated in esophageal cancer tissues and cells and then linked its low expression to cancer progression. Bioinformatic analysis predicted KDM5B as a target gene of let-7i, which was confirmed by a dual-luciferase reporter assay. Loss- and gain-of function approaches were adopted to examine the interactions of let-7i, KDM5B, SOX17, and GREB1 in vitro and in vivo. Overexpression of let-7i suppressed esophageal cancer cell proliferation and invasion and promoted apoptosis. Mechanistic investigation showed that let-7i targeted and inhibited KDM5B expression, whereas KDM5B enhanced H3K4me3 at the SOX17 promoter region. Overexpression of let-7i suppressed the expression of GREB1 in esophageal cancer cells by regulating the KDM5B/SOX17 axis in vivo and in vitro. Taken together, our findings reveal the tumor-suppressive properties of let-7i in esophageal cancer in association with an apparent KDM5B-dependent SOX17/GREB1 axis. This study offers a potential prognostic marker and therapeutic target for esophageal cancer.
