A comparison of the risk of bovine spongiform encephalopathy infectivity in beef from cattle younger than 21 months in Japan with that in beef from the United States as assessed by the carcass Maturity Score.
Journal of food protection, 2008Co-Authors: Katsuaki Sugiura, Gary C. SmithAbstract:After the detection of the first case of bovine spongiform encephalopathy (BSE) in the United States in December 2003, the Japanese government halted all imports of U.S. beef. The BSE risk in beef is partly dependent on the slaughter age of the cattle from which it is derived. In Japan, all cattle 21 months old and older are screened using a rapid diagnostic test, while in the United States, routine BSE testing is not done at any age of slaughter cattle. In the United States, there is no nationally mandated cattle identification system that enables cattle younger than 21 months to be identified. Therefore, all beef potentially produced for export to Japan must be from cattle that are age verified as younger than 21 months old or be classified by the U.S. Department of Agriculture using a carcass Maturity Score, which in turn is related to the age of the animal from which the beef is derived. After consulting the Food Safety Commission, the Japanese government decided on 12 December 2005 to allow importati...

The impact of premature birth on dental maturation in the permanent dentition.
Clinical oral investigations, 2018Co-Authors: Liselotte Paulsson, Sara Arvini, Niclas Bergström, Gunilla Klingberg, Christina LindhAbstract:Objectives To evaluate tooth development and calculate dental Maturity Score in prematurely born children and to compare the findings with full-term born children. Material and methods Nine-year-old preterm children were selected from the Swedish Medical Birth Register. One group consisted of 36 extremely preterm children (born before week 29), and the other included 38 very preterm children (born during weeks 29 to 32). Panoramic radiography was performed on each child and the preterm children were compared with 42 full-term born children. Five observers independently assessed the tooth development stages for all teeth in the left mandible (31-37) on the panoramic radiographs according to the method described by Demirjian et al. (Hum Biol 45:211-227, 1973). Data from tooth development stages were compiled and converted into a dental Maturity Score for each group. Kappa values were calculated for intra- and inter-observer agreement. Results When the different development stages for each individual tooth were compared, all observers presented a significant delay in the Maturity of tooth 37 for the extremely preterm group (p ≤ 0.002). The extremely preterm group had a significantly lower dental Maturity Score than the full-term group, as assessed by each observer (p ≤ 0.006). Kappa values for inter-observer agreement varied between 0.31 and 0.71 depending on tooth and intra-observer agreement was between 0.16 and 1.0. Conclusions At age 9, the extremely preterm children had a general delay in tooth development. Clinical relevance The increased survival rate of extremely preterm babies adds a new group of children to society. Dental clinicians should be aware that the delay in tooth development could impact the timing of orthodontic diagnostics and potential treatment.

Implication of Flow Cytometry-Based Maturity Score in Risk Stratification of Acute Myeloid Leukemia in Adult Egyptians
QJM: An International Journal of Medicine, 2020Co-Authors: E A M Eldebaky, H M E Afifi, S A Pessar, A M S AhmedAbstract:Abstract Background Already for decades, controversy exists as to whether immunophenotyping has a prognostic significance in acute myeloid leukemia (AML). However, the impact of the immunophenotypic assessment of blast Maturity is largely unknown. Objectives Studying the influence of the degree of immunophenotypic Maturity, via the application of the flow-cytometric based Maturity Score, on the clinical outcome as well as the laboratory and clinical parameters of patients with AML. Methods This study was conducted on 40 newly diagnosed AML patients with the quantifications of the variable expressions of three early myeloid progenitor markers namely CD34, CD117 and TdT. After that, the estimation of the blast Maturity was based on a previous Score proposed in a study by Schneider et al. (2015). Results Out of forty patients enrolled, 8 patients (20%) were assigned to the mature group whereas 32 patients were assigned to the immature group. There was no statistically significant difference between both groups in terms of demographics, clinical and laboratory data, cytogenetic risk groups as well as treatment outcome determined by mortality and response to chemotherapy on day 28 and at 6 months. Mature group showed slightly higher median survival in comparison to the immature group. Conclusion There is no evident relationship between Maturity Score of the blast population of a patient and the clinical outcome despite mild prolongation of median survival of the mature group. Higher sample size is needed to confirm this observation.
