Atrial fibrillation (AF) is the most common arrhythmia among the elderly, and more frequently occur in those with chronic kidney disease (CKD). Left atrial appendage occlusion (LAAO) is used as a mechanical alternative approach for prevention of AF-related thromboembolisms. This meta-analysis was conducted to provide suggestions for the clinical application of LAAO in AF patients with CKD. The incidence of perioperative adverse events and other clinical effects after operation was by a single rate meta-analysis. Results showed that incidence of adverse events in the perioperative period after LAAO was generally low, with only pericardial effusion / tamponade (1.90%) and mortality rate (1.10%). During the follow-up period, the incidence of stroke/transient ischemic attack (TIA) and bleeding were 2.17% and 4.53%, respectively. A low incidence rate of adverse events was found in the perioperative period following LAAO. These results indicate that LAAO more effectively prevents the occurrence of stroke/TIA and minimizes bleeding events than oral anticoagulants.
Supramolecular hydrogels involved macrocycles have been explored widely in recent years, but it remains challenging to develop hydrogel based on solitary macrocycle with super gelation capability. Here, the construction of lantern[33]arene‐based hydrogel with low critical gelation concentration (0.05 wt%), which can be used for efficient oil–water separation, is reported. The lantern[33]arenes self‐assemble into hydrogen‐bonded organic nanoribbons, which intertwine into entangled fibers to form hydrogel. This hydrogel which exhibits reversible pH‐responsiveness characteristics can be coated on stainless‐steel mesh by in situ sol‐gel transformation. The resultant mesh exhibits excellent oil–water separation efficiency (>99%) and flux (>6 × 104 L m−2 h−1). This lantern[33]arene‐based hydrogel not only sheds additional light on the gelation mechanisms for supramolecular hydrogels, but also extends the application of macrocycle‐based hydrogels as functional interfacial materials.
In this paper, the relationship between meteorological conditions and diseases is investigated. The relative fitting errors for nine kinds of diseases are within the limit of 0.048‐0.228. These results are the bases of researches of mechanism and a component of the numerical model which has been used in the prediction of diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
