The American College of Phlebology Guidelines Committee performed a systematic review of the literature regarding the clinical impact and treatment of incompetent accessory saphenous veins. Using an accepted process for guideline developments, we developed a consensus opinion that patients with symptomatic incompetence of the accessory great saphenous veins (anterior and posterior accessory saphenous veins) be treated with endovenous thermal ablation (laser or radiofrequency) or ultrasound-guided foam sclerotherapy to eliminate symptomatology (Recommendation Grade 1C).

Abstract Single crystals of (I): EuBeGd2O5, (II): Ca0,4Sr0,6BeSm2O5, (III): Ba0,25Ca0,75BeNd2O5 and (IV): Ba0.36Sr0.64BeNd2O5 were prepared by (I): plasma torch and (II)-(IV ): CO2-LASER technique. X-Rayo investigations lead to (I) monoclinic (space group C52h-P21/c, a = 7.126, b = 6.457, c = 9.394 Å , β = 90.40°) and (II)-(IV) orthorhombic symmetry (D162h-Pnma). (II: a = 9.454, b = 7.142, c = 6.490 Å; III: a = 9.508, b = 7.188, c = 6.531 Å; IV: a = 9.642, b = 7.295, c = 6.614 Å). In contrary to the phases M1-xM′xBeLn2O5, EuBeGd2O5 is characterized by an ordered distribution of Eu2+ and Gd3+ inside of the Kagomé network.

Laser processing ceramic materials is a new application of laser technique. This paper presents the study of laser processing parameters of glaze cladding. It found out that the parameters of laser processing affected the morphology of glaze cladding significantly. Within the experimental conditions, rise of output power or drop of processing speed can increase the depth of melted zone and the width of glaze cladding, vice versa.

Research Hotspots

BACKGROUND With the increase in the number of biomedical scientific publications, it is of great value to characterize the research status of subtopics in this field, especially in the specific field of diseases. However, there has not been a fully automated pipeline for mining and analysing research hotspots in this field. OBJECTIVE We propose a completely automatic method based on natural language processing technology to analyize scientific innovations in a specific disease area. METHODS The whole pipeline consists of three steps, i.e. keyphrase extraction, clustering and cluster naming. The pipeline expands the existing literature analysis methods (including keyphrase extraction, document clustering, and paper ranking), adds advanced semantic mining technology (contextualized embeddings from pre-trained language models), and designs a document cluster naming strategy based on core document mining and topic-related phrase mining. With this pipeline, a full picture of the field of a specific disease is established. Distinct document clusters are generated to describe various subfields in disease-related research. Core documents and topic-related phrases are used to name clusters to interpret the concerns that researchers care about. Besides, the relations between clusters are analysed. Finally, several important clusters are analysed, whose core citation paths illustrate the research roadmap for a certain subfield and whose phrases directly describe the hotspots in each subfield. RESULTS We applied the method in the field of cataracts. From the 35117 cataract publications, the proposed method has extracted phrases with a high frequency like cataract extraction, cataract formation, intraocular pressure, etc. The method also found the most important documents in this field, which reveal the flow of research hotspots over time. 23 communities are generated and the top 10 topic-related phrases and core documents are extracted to name the communities. The cluster with the most paper is mainly about cataract formation. The cluster with the most high-impact papers focuses on common cataract diseases related to cataract epidemiology surveys. The cluster with the highest novelty and the highest progressiveness is related to the femtosecond laser technique. CONCLUSIONS This fully automated method can achieve the full picture of the research status of the field of a specific disease, without expert annotation.
