- lood pressure alterations during hemodialysis were related to changes in body fluid in 14 patients with chronic renal failure. Changes in plasma volume (PV) and extracellular volume (ECV) were calculated from determinations of fluid volumes before and after hemodialysis, using 125I-albumin and 51Cr EDTA respectively. Reduction in body water was estimated from body weight changes. Weight loss was 3.3 ± 0.3 kg (range 1.8-6.0 kg). The relative reduction of fluid was greater in the ECV, 21.6 ± 3.2%, compared to plasma volume, 6.9 ± 1.8%. The reduction in systolic blood pressure was related to both absolute (r = 0.66, p < 0.05) and relative PV reduction (r = 0.72, p < 0.02). There was no correlation between blood pressure reduction and weight loss or ECV changes. Only minor alterations were found in diastolic blood pressure. Plasma volume maintenance relates to blood pressure changes. Plasma volumemonitoring could be useful for improving intradialytic hemodynamic control.

Journal article (peer-reviewed)abstract
- Fluid volume changes during hemodialysis was monitored by continuous whole body impedance measurements. The fluid changes recorded using this method was compared to fluid volume changes measured in plasma water (PV) using125I-albumin, and extracellular volume (ECV) using51Cr-EDTA before and after treatment, and total body water (TBW) changes reflected by continuous bed scale monitoring. Changes in impedance correlated to TBW changes, r=0.80, p<0.001, while correlations to changes in ECV and PV were: r=0.57 and r=0.55, respectively, p<0.05. Alterations in body fluid volumes recorded with whole body impedance is best correlated to total body water changes. The use of continuous whole body impedance monitoring has been shown to offer a simple non-invasive method for recording total body water changes during hemodialysis.

Scripted knowledge packages : implicit and explicit constraints on comprehension and memory
- 1993
-
Doctoral thesis (other academic/artistic)abstract
- The aim of the present thesis was (a) to specify how the use of predictive inferences in comprehension is constrained by scripted knowledge packages, (b) to examine recall for scripted representations, and (c) to specify mechanisms underlying the interplay between script-based constraints on predictive inferences and memory for these generic knowledge representations. In fourteen experiments, lipreading represented a method to detect implicit and explicit constraints on predictive inferences imposed by typicality, abstraction, and temporal order. To compare comprehension and recall, repetition priming constituted an additional approach where implicit memory was assessed by the lipreading task, and explicit memory by a free recall task. Based on the collected data, an implicit-explicit principle is suggested which also summarizes the main core of the SPICER-framework. According to the SPICER, typical and basic scripted representations are supposed to constitute implicit representations with a semantic state of accessibility, strong in predictive power. In contrast, atypical and specific representations are assumed to constitute explicit representations with an episodic state of accessibility, weak in predictive power. In comprehension, an implicit route of script activation always guides predictive inferences at typical and basic levels of representation. In recall, an explicit search for target episodes is always constrained by atypical and specific levels of representation. SPICER also provides potential insights into the use of technical hearing aids and lipreading, memory distinctions and memory disorders, as well as into educational issues.
