A set of 334 commercial virgin olive oil (VOO) samples were evaluated by six sensory panels during the H2020 OLEUM project. Sensory data were elaborated with two main objectives: (i) to classify and characterize samples in order to use them for possible correlations with physical–chemical data and (ii) to monitor and improve the performance of panels. After revision of the IOC guidelines in 2018, this work represents the first published attempt to verify some of the recommended quality control tools to increase harmonization among panels. Specifically, a new “decision tree” scheme was developed, and some IOC quality control procedures were applied. The adoption of these tools allowed for reliable classification of 289 of 334 VOOs; for the remaining 45, misalignments between panels of first (on the category, 21 cases) or second type (on the main perceived defect, 24 cases) occurred. In these cases, a “formative reassessment” was necessary. At the end, 329 of 334 VOOs (98.5%) were classified, thus confirming the effectiveness of this approach to achieve a better proficiency. The panels showed good performance, but the need to adopt new reference materials that are stable and reproducible to improve the panel’s skills and agreement also emerged.

Abstract Abstract 1446 Background: After many years of use, the French-American-British (FAB) system for classification of AML has been replaced by that of the World Health Organization (WHO), as revised in 2008 (Blood 2009;114: 937–51). While unlike FAB, WHO uses genetic and clinical information to specify AML subtypes, the FAB system remains embedded in the WHO category of “AML not otherwise specified” (NOS). Here we ask whether the subdivision by FAB of AML NOS is of prognostic significance. Methods: FAB data were available on 970 newly-diagnosed patients treated on various SWOG protocols from 1986 to 2009. The protocols generally called for 3+7 type induction therapy. Exclusion of patients with recurrent genetic abnormalities, therapy-related AML (T-AML), or AML with myelodysplasia related changes (MDS-AML), as stipulated in WHO 2008 (NPM1 and CEBPA mutation status was unavailable), left 447 with AML NOS whose FAB type was recorded. We used multivariate analyses adjusting for age, sex, cytogenetic risk (SWOG criteria), pretreatment performance status, blood counts, and marrow blasts, to assess whether FAB was independently associated with outcome in these 447 patients and used areas under the receiver operator characteristic curve (AUC) to quantify the predictive ability of FAB, with AUC of 1.0 indicating perfect prediction and an AUC of 0.5 equivalent to a coin flip. Results: The 447 patients had median age of 58 years, CR rate 56% and median survival 17.2 months. Given the association between T-AML or MDS-AML and FAB types M6 or M7 (p=0.02 in this dataset), only 2% of the 447 patients were M6 or M7; 8% were M0, 27% M1, 26% M2, 25% M4, and 12% M5 (we excluded patients with M3). CR rates were 47% M0, 56% M1, 53% M2, 54% M4, 72% M5, and 45% M6 or M7. Survival probability was longest with M6/M7 followed by M5. The multivariate analyses showed the following for the effect of FAB (considered as M0, M1, M2, M4, M6/M7): Results were similar regardless of whether we considered FAB as above or grouped as M0, M1/M2, M4/M5, M6/M7. In particular, FAB was not associated with any outcome and its removal from more complete adjusted models had little effect on the models' predictive ability. Conclusion: These results question the utility of the FAB system as embedded in WHO 2008. Disclosures: No relevant conflicts of interest to declare.

Multivariate analyses of males of 25 species of the Old World army ant genus Dorylus were used to investigate taxonomic structure inherent in the morphological data gathered. Results were compared both with the current subgeneric classification of this genus and with results from a similar study on the major workers. Males are phenetically more divergent than major workers. The subgenera Rhogmus, Alaopone, and Typhlopone appear deserving of continued individual status, but species of Anomma and Dorylus (s.s.) form one diverse taxon. Although the single species of Dichthadia is relatively distinctive in this study, a conservative classification would place it with species of Dorylus (s.s.).

The study aimed at classifying an equine skull stored in Museu da Ciência da Universidade de Coimbra, Coimbra (Portugal) on the basis of its morphology using multivariate analyses. A visual appraisal had revealed that it was not from a horse. Nineteen cephalic measurements were obtained and compared with available data of horses of different groups (poneys, trait and saddle), equine hybrids, Przewalski’s horse (Equus przewalskii), wild and domestic asses, and quaggas (Equus quagga). Multivariate analysis plus head profile allowed us to assign the skull to a mare hinny -the hybrid between a jenny (female donkey) and a stallion (male horse). The research highlights the possibilities of categorization of equid skulls according to morphometry but with a need to consider qualitative traits, as head profiles. But more such studies are needed to be conducted to establish clearly differences between mules and hinnies, especially among sympatric populations.

A total of 275 successive referrals to a university child psychiatry unit out-patient department were examined using the Child Depression Inventory. Of these, 95 children were examined further by a structured clinical interview, and the relationship between different instruments for the assessment of depression in childhood was investigated. Just over one-third of the children (35%) had significant depression, and it was found that depression may be missed unless children with other psychiatric diagnoses are examined closely. Multivariate analyses of the clinical data provided factorial validation of diagnoses when employing different clinical diagnostic schemas.
