Objective To evaluate the effect of releasable sutures on shallow anterior chamber, filtering bleb and long-term intraocular pressure (IOP). Methods We searched MEDLINE (1971 to 2007), OVID (1971 to 2007) and National Science and Technology Library (1971 to 2007). Randomized controlled trials (RCTs) of the effect of releasable sutures on trabeculectomy were collected. Study selection and assessment, data collection and analyses were undertaken and cross-checked by two reviewers. Meta-analyses were performed with The Cochrane Collaboration’s RevMan 4.2.10 software. Results Six RCTs involving 341 eyes were included. Significant differences were observed in the reduction of postoperative shallow anterior chamber (RD –0.23, 95%CI –0.31 to –0.14, Plt;0.000 01) and functional filtering blebs (RD –0.15, 95%CI –0.27 to –0.02, P=0.02). But, no differences were observed for the control of long-term IOP (SMD –0.13, 95%CI –0.37 to 0.10, P=0.27). Conclusion The evidence currently available showed that releasable sutures could reduce the incidence of shallow anterior chamber and has no beneficial effect in controlling long-term IOP. The current evidence is insufficient to define the efficacy of maintaining functional filtering blebs. Further large-scale, high-quality randomized controlled trials are needed.
In the intensive care units of Japan, nafamostat mesilate (NM) is the most used anticoagulant of continuous blood purification, with the rate of up to 85%. Its biggest characteristic is not to reduce the life of the filter in the group of patients with high risk of bleeding, and it can be safely used. However, there are not a few reports about severe anaphylaxis, when the symptoms of anaphylaxis is recognized after the start of continuous renal replacement therapy, it should be kept in mind that it is NM hypersensitivity. In addition, for an expensive drug, it may be required to be limited in the cases of risk of bleeding complications. NM has been developed for nearly 30 years, so it has high reliability in Japan. However, in the same case, regional citrate anticoagulation is recommended internationally. It may need a randomized controlled trial with regional citrate anticoagulation to prove the real effectiveness of NM.
This article reviews Chinese nomenclature of renal replacement therapy and extracorporeal blood purification currently utilized to manage acute kidney injury and other organ dysfunction syndromes in critically ill patients, based on the recent reports of a consensus expert conference of Nomenclature Standardization Initiative Alliance. We provide a detailed description of the performance characteristics of membranes, filters, transmembrane transport of solutes and fluid, flows, and methods of measurement of delivered treatment, common definitions, components, techniques, and operations of the machines and platforms as well as the renal replacement therapy techniques in detail with the relevant technologies, procedures, operations, and recent developments in other extracorporeal therapies, including therapeutic plasma exchange, multiple organ support therapy, liver support, lung support, and blood purification in sepsis. We believe this nomenclature review will serve future use of terminology in publications, research, clinical operations and therapy platforms to enable consistent data collection and comparison.
The non-invasive brain-computer interface (BCI) has gradually become a hot spot of current research, and it has been applied in many fields such as mental disorder detection and physiological monitoring. However, the electroencephalography (EEG) signals required by the non-invasive BCI can be easily contaminated by electrooculographic (EOG) artifacts, which seriously affects the analysis of EEG signals. Therefore, this paper proposed an improved independent component analysis method combined with a frequency filter, which automatically recognizes artifact components based on the correlation coefficient and kurtosis dual threshold. In this method, the frequency difference between EOG and EEG was used to remove the EOG information in the artifact component through frequency filter, so as to retain more EEG information. The experimental results on the public datasets and our laboratory data showed that the method in this paper could effectively improve the effect of EOG artifact removal and improve the loss of EEG information, which is helpful for the promotion of non-invasive BCI.
