Effect of intradialytic change in blood pressure and ultrafiltration volume on the variation in access flow measured by ultrasound dilution

Hoon Suk Park, Seok Hui Kang, Byung Ha Chung, Bum Soon Choi, Cheol Whee Park, Chul Woo Yang, Yong-Soo Kim
2013 Kidney Research and Clinical Practice  
Methods: Access flow was measured 30 minutes, 120 minutes, and 240 minutes after the start of HD by ultrasound dilution in 30 patients during 89 HD sessions and evaluated for variation.  ...  Conclusion: We conclude that the variation in access flow during HD is relatively small. Decreased blood pressure is a risk factor for variation in access flow measured by ultrasound dilution.  ...  Based on our results, we would recommend that any significantly decreased measurement of access flow in a patient in whom MAP had decreased by Z5% should be rechecked at the next session.  ...

Antimicrobial dosing in prolonged intermittent renal replacement therapy: a systematic review

Matthew D. M. Rawlins, Jeanie Misko, Jason A. Roberts
2021 Journal of Pharmacy Practice and Research  
With the exception of vancomycin and meropenem, few antimicrobials had sufficient data available from which reasonable empiric dosing regimens can be recommended.  ...  PIRRT settings varied between institutions, including filter surface area, duration of PIRRT and type of dialyser used.  ...  Daptomycin should be dosed daily at the end of a PIRRT session at doses similar to that used in normal renal function. Ethambutol standard dosing of 15 mg/ kg/day should be supported by TDM.  ...

SBQ: A Simple Scheduler for Fair Bandwidth Sharing Between Unicast and Multicast Flows [chapter]

Fethi Filali, Walid Dabbous
2002 Lecture Notes in Computer Science  
To implement our approach, we propose to use a two classes CBQ/WRR-like scheduler [6]: one for the unicast flows and the other one for multicast flows.  ...  In this paper, we propose a simple scheduler called SBQ (Service-Based Queuing) to share the bandwidth fairly between unicast and multicast flows according to a new definition of fairness referred as the  ...  We plot in Figure 6 (b), the variation of the normalized average rate as a function of the number of congested links.  ...

Improving short utterance i-vector speaker verification using utterance variance modelling and compensation techniques

A. Kanagasundaram, D. Dean, S. Sridharan, J. Gonzalez-Dominguez, J. Gonzalez-Rodriguez, D. Ramos
2014 Speech Communication  
Well established methods such as linear discriminant analysis (LDA), source-normalized LDA (SN-LDA) and within-class covariance normalisation (WCCN) exist for compensating the session variation but we  ...  To compensate for utterance variations in short i-vector speaker verification systems using cosine similarity scoring (CSS), we have introduced a short utterance variance normalization (SUVN) technique  ...  There are two key recommendations arising from our research for i-vector based speaker verification with short utterances: (i) when a CSS i-vector approach is used, we recommend the use of SUVN [LDA]  ...
