Background Application of the Stewart-Hamilton equation in the thermodilution technique requires flow to be constant. In patients in whom ventilation of the lungs is controlled, flow modulations may occur leading to large errors in the estimation of mean cardiac output. Methods To eliminate these errors, a modified equation was developed. The resulting flow-corrected equation needs an additional measure of the relative changes of blood flow during the period of the dilution curve. Relative flow was computed from the pulmonary artery pressure with use of the pulse contour method. Measurements were obtained in 16 patients undergoing elective coronary artery bypass surgery. In 11 patients (group A), pulmonary artery pressure was measured with a catheter tip transducer, in a partially overlapping group of 11 patients (group B), it was measured with a fluid-filled system. For reference cardiac output we used the proven method of four uncorrected thermodilution estimates equally spread over the ventilatory cycle. Results A total of 208 cardiac output estimates was obtained in group A, and 228 in group B. In group B, 48 estimates could not be corrected because of insufficient pulmonary artery pressure waveform quality from the fluid-filled system. Individual uncorrected Stewart-Hamilton estimates showed a large variability with respect to their mean. In group A, mean cardiac output was 5.01 l/min with a standard deviation of 0.53 l/min, or 10.6%. After flow correction, this scatter decreased to 5.0% (P < 0.0001). With no bias, the corresponding limits of agreement decreased from +/- 1.06 to +/- 0.5 l/min after flow correction. In group B, the scatter decreased similarly and the limits of agreement also became +/- 0.5 l/min after flow correction. Conclusion It was concluded that a single thermodilution cardiac output estimate using the flow-corrected equation is clinically feasible. This is obtained at the cost of a more complex computation and an extra pressure measurement, which often is already available. With this technique it is possible to reduce the fluid load to the patient considerably.

Abstract Objective To test the interrater reliability when using the codes of the 11th revision of the International Classification of Diseases (ICD)-11 beta draft as well as ICD-10 and to explore the usability of the ICD-11 beta draft and the applicability of ICD-11’s Supplementary section for functioning assessment in hand injuries and diseases. Design We conducted a validation study of the ICD-11 beta draft complemented by a single-centre study to collect clinical routine data on functioning. Setting German hand surgery clinics. Participants Twenty-three physicians coded real-life cases containing diagnostic information on hand injuries and diseases. Additionally, clinical information of 100 patients was coded by 6 physicians and a nurse using ICD-11’s Supplementary section for functioning assessment. Main Outcome Measures Physicians coded 210 cases using the ICD-11 beta draft and ICD-10. Krippendorff’s alpha was calculated. Clinical routine data was coded using 38 functioning categories. Results Interrater reliability (Krippendorff’s alpha) of 0.67 for ICD-11 coding and 0.71 for ICD-10 coding was obtained, indicating substantial agreement. However, physicians reported a high proportion of problems with ICD-11 coding and slightly fewer problems with ICD-10 coding. The collected data on functioning could be mapped to ICD-11’s Supplementary section for functioning assessment. For some data, however, only unspecific codes were available. Conclusions Interrater reliability of ICD-10 and ICD-11 was satisfactory. Training material for ICD-11 is needed to further improve reliability and usability. Future users of ICD-11 should be encouraged to use the Supplementary section for functioning assessment to shed light on the problems patients experience in everyday life.

The residual in equation 2 of Suchit Aurora's article in the September 2001 issue, “Health, Human Productivity, and Long-Term Economic Growth,” should have been shown as {\hat{\varepsilon}}_t to correspond to the notation used in equations 6 and 7. The corrected equation is \Delta\ln y_t = \mu + \xi\ln h_t + \sum\limits^{-m}_{i=m}\phi_i\Delta\ln h_{t+i}+\hat{\varepsilon}_t\qquad t=1,2,3,\ldots T

SUMMARY Distension of the vagina by an inflated balloon induces milk ejection in goats. This reflex (the Ferguson reflex) is based on a neurohormonal mechanism. In three goats the reflex was abolished after bilateral section of the complex pelvic nerves plus caudal rectal nerves. Bilateral section of the pelvic nerves only, caused a complete elimination of the reflex in 11 out of 13 goats; in the two remaining animals, the reflex was abolished after a supplementary section of the pudendal nerve plus caudal rectal nerves. The reflex remained intact in one goat in which first the caudal rectal nerves and subsequently the pudendal nerve were cut. Elimination of the Ferguson reflex was accompanied by a marked reduction of the intensity of straining movements which are normally induced by distension of the vagina. Bilateral section of the pelvic nerves provoked a severe but temporary paralysis of the large intestine with blocking of the defaecation reflex. It is suggested that in ruminants the afferent pelvic nerves are involved in the release of oxytocin and in the intense straining occurring during the phase of expulsion at parturition.

AbstractAir permeability was determined for concretes of variable porosity (w/c ratio of 0.33, 0.50, and 0.67). The reproducibility of the test and the ability to characterize the permeability of different concrete were evaluated. Results indicate that air permeability test gives suitable reproducibility with a margin of error of 10%, which tends to improve with increase in w/c ratio. The difference in air permeability of concretes with the w/c ratios investigated are distinguishable by this technique. Furthermore air permeability coefficients used were modified with equations derived in accordance to Darcy's law, and the resulting air permeabilities compared. Data calculated with an air permeability coefficient based on mean radius pore (corrected equation) appears to give a more realistic value with greater differentiation between the ranges. Values were determined on specimens after 28 days, maintained at room temperature (50% RH), then again after an additional 2 days at 60°C in a ventilated oven. Oven-dried specimens exhibit significantly greater air permeability.

ABSTRACTSummaryOne of the main goals of proteomics is to understand how point mutations impact on the protein structure. Visualization and clustering of point mutations on user-defined 3 dimensional space can allow researchers to have new insights and hypothesis about the mutation’s mechanism of action.Availability and ImplementationWe have developed an interactive I-PV add-on called INDORIL to visualize point mutations.
