Impact of comorbidity indexes on non-relapse mortality.

Comorbidity indexes (CI) have been reported to predict non-relapse mortality (NRM) and overall survival after allogeneic hematopoietic stem cell transplantation (HSCT) (Charlson's comorbidity index (CCI), hematopoietic cell transplantation CI (HCT-CI) and the pre-transplantation assessment of mortality (PAM) score). Which of these indexes best predict survival is unknown yet. We retrospectively studied 286 patients who underwent allogeneic HSCT. HCT-CI and PAM scores required grading according to pre-transplant pulmonary function tests (PFTs), which were lacking for some patients. We thus designed a reduced HCT-CI and an adjusted PAM, without results of PFTs. Using CCI, 25% of patients had indexes of 1 or more; median reduced HCT-CI score was 1; median adjusted PAM score was 24. The discriminative properties of the three CIs were rather low in our population. Comparison of patients and transplant characteristics between our and Seattle group's cohorts, however, revealed significant differences in more children, in more cord blood HSCT and in HSCT for Fanconi anemia in St Louis. Finally, multivariate analysis of scoring items revealed that age, matched unrelated or mismatched donor and hepatic disease were associated with NRM in our cohort. Translating use for patient's counseling or decision to proceed to transplant of these CIs will need prospective studies in a large independent cohort

Bone marrow transplantation in severe aplastic anaemia: a survey of the European Group for Bone Marrow Transplantation (E.G.B.M.T.)

A survey of the results of bone marrow transplantation for severe aplastic anaemia in 13 European teams is reported. 159 questionnaires were analysed by univariate and multivariate analysis. The overall 1 year survival was 41.2%. The chance of survival was decreased by the presence of infection before grafting and by the use of female donors. The conditioning regimen did not influence survival. Graft rejection was influenced by the conditioning regimen and the sex of the donor. Graft-versus-host disease was influenced by the conditioning regimen, and the age and the sex of the recipient. This study defines prognostic indices which may be helpful in determining the likelihood of success after marrow transplantation for severe aplastic anaemia

The effect of lip-reading on primary stream segregation

International audienceLip-reading has been shown to improve the intelligibility of speech in multitalker situations, where auditory stream segregation naturally takes place. This study investigated whether the benefit of lip-reading is a result of a primary audiovisual interaction that enhances the obligatory streaming mechanism. Two behavioral experiments were conducted involving sequences of French vowels that alternated in fundamental frequency. In Experiment 1, subjects attempted to identify the order of items in a sequence. In Experiment 2, subjects attempted to detect a disruption to temporal isochrony across alternate items. Both tasks are disrupted by streaming, thus providing a measure of primary or obligatory streaming. Visual lip gestures articulating alternate vowels were synchronized with the auditory sequence. Overall, the results were consistent with the hypothesis that visual lip gestures enhance segregation by affecting primary auditory streaming. Moreover, increases in the naturalness of visual lip gestures and auditory vowels, and corresponding increases in audiovisual congruence may potentially lead to increases in the effect of visual lip gestures on streaming
