The work confirms that more detailed quantitative assessments of the spatial pattern of PET imaging data of tumor masses, beyond the maximum FDG uptake (SUV(max)) and previously considered measures of heterogeneity, provide improved prognostic information for potential input
to treatment decisions for future patients.”
“Objectives: Lumping and Epoxomicin Proteases inhibitor splitting refer to the scope of a systematic review question, where lumped reviews are broad and split are narrow. The objective was to determine the frequency of lumping and splitting in systematic reviews of reminder interventions, assess how review authors justified their decisions about the scope of their reviews, and explore how review authors cited other systematic reviews in the field.
Study Design and Setting: A descriptive approach involving a content analysis and citation bibliometric study of an overview of 31 systematic reviews of reminder interventions.
Results: Twenty-four of 31 reminder reviews were split, most frequently across one category (population, intervention, study design, outcome). Review authors poorly justified their decisions about the scope of their reviews and tended not to cite other similar reviews.
Conclusion: This study demonstrates that for systematic reviews of reminder interventions, splitting is more common than
lumping, with most reviews split by condition or targeted behavior. Review authors poorly justify the need for Dinaciclib their review and do not cite relevant literature to put their reviews in the context of the available evidence. These factors may
have contributed to a proliferation of systematic reviews of reminders and an overall disorganization of the literature. (C) 2012 Elsevier Inc. All rights reserved.”
“Objective: The aim of this study was to investigate the developmental relationship between adenoid tissue volume and mastoid air cell volume, VS-6063 using a 3D reconstruction technique. Study design: Cross-sectional retrospective study.
Subjects and methods: Multislice computed tomography (MSCT) images were obtained using three-dimensional (3D) reconstruction and volume-rendering techniques (VRT). The subjects were 63 boys and 37 girls, 3-16 years of age. The volumes of bilateral mastoid air cells and adenoids marked in axial-coronal-sagittal planes were calculated. The patients were grouped into three categories according to adenoid tissue volume, total mastoid volume (TMV), and age.
Results: No significant difference was noted between the right mastoid volume (RMV) and the left mastoid volume (LMV) or between age and sex (p = 0.368; p = 0.549; p = 0.454). The incremental increase in adenoid tissue volume did not correlate with TMV (r = -0.161, r = -0.279, r = 0.015). The incremental increase in TMV did not correlate with the volume of adenoid tissue (r = 0.024, r = 0.148, r = 0.017).
