Summary Aim of this study was a characterization of radioiodine therapy (RIT) failures in Graves’ disease without simultaneous Carbimazole. Method: 226 patients with a confirmed diagnosis of Graves’ disease received 686.8 ± 376.4 MBq of iodine-131 orally for thyroid ablation. Target dose was 250 Gy. All patients were followed up for 6 months. Therapy failures were compared with successes regarding possible influencing variables initial thyroid volume, thyroid function, immune activity (TRAb), 1-131 uptake, effective half-life, absorbed energy dose, age and gender. Results: 212 of 226 patients (93.8%) were treated successfully, 14 (6.2%) showed a hyperthyroidism relapse within 6 months which required a second radioiodine therapy. A success rate of 92.5% (62/67) could also be achieved with 67 patients who were hyperthyroid at the time of RIT. Compared to the therapy successes, the 14 failures achieved significantly lower absorbed doses (223.8 ±76.6 Gyvs. 285.2 ±82.1 Gy, ρ <0.005), but with no significant differences regarding age, thyroid volume, function or TRAb (all ρ >0.2). Of the 14 failures, η = 8 reached an absorbed dose <200 Gy and η = 1 a dose <250 Gy, although 5 of the failures reached an absorbed dose of >250 Gy. Stepwise logistic regression revealed only absorbed energy dose as a variable significantly influencing therapy success (p <0.005), but no influence of initial thyroid volume, function, TRAb value, age (all ρ >0.2) or gender (p = 0.13). Two-tailed Fisher’s exact test showed no significant influence of gender on success rates (failures/successes: male 1 /36, female 13/176, ρ = 0.48). Conclusions: Except for the absorbed energy dose, no other significant variable influencing the outcome of radioiodine therapy in Graves’ disease without simultaneous Carbimazole could be found. It should be noted, though, that 5 therapy failures (2.2%) reached an absorbed energy dose of >250 Gy.

Review Protocol

Anorexia Nervosa (AN) is a serious mental health condition, which commonly follows a chronic course, termed severe-enduring AN (SE-AN). Recent evidence suggests SE-AN may be underpinned by an interaction between genetic risk factors, the endocrinological, immune and metabolic systems and deficiencies in neural structures. One structure found to be implicated over the course of AN is the hippocampus, which similarly has shown to be affected in other psychiatric disorders. The hippocampus is involved in processes such as memory and learning, as well as in the regulation of food intake. The literature on the hippocampus and AN is relatively heterogeneous and no reviews of hippocampal integrity in AN have been conducted. We will conduct a systematic scoping review of hippocampal volume, function and connectivity, as well as molecular components associated with hippocampal neurogenesis, to assess the variability in the literature and the current consensus on the hippocampus in AN.We will use methods based on the Joanna Briggs Institute scoping review methods manual. Studies of any design in populations of AN with outcomes pertaining to our inclusion criteria will be located using an electronic database search of MEDLINE (PubMed), Web Of Science and PsychINFO. Two reviewers will independently screen titles, abstracts and full-texts and chart data of eligible studies. Study characteristics will be summarised during data analysis. Reported outcomes will include main study findings and methodology.

This study aims to describe the mathematical needs that support competency in the Technical and Business of Motorcycle. This study involved the participation of teachers of Technical and Motorcycle Business and automotive engineering academics. Participants were vocational teachers and lecturers in the Ciamis and Tasikmalaya areas who were accessed by researchers. Data on mathematical needs in technical and motorcycle business are obtained from views of participants and vocational document searches. Participants identify the mathematical needs of the basic competencies in subjects of expertise competency (C3). The results of the study were obtained: (1) measurement, numbers, geometry, algebra, and statistics is the scope of mathematics that supports the competency in the Technical and Business of Motorcycle with an emphasis on the concept of comparison, area, volume, function, and conversion; (2) mathematical relational understanding is needed to solve problems. These results indicate that mathematics with mathematical understanding is needed in the Technical and Motorcycle Business Competencies.

ABSTRACT We study the Voronoi volume function (VVF) – the distribution of cell volumes (or inverse local number density) in the Voronoi tessellation of any set of cosmological tracers (galaxies/haloes). We show that the shape of the VVF of biased tracers responds sensitively to physical properties such as halo mass, large-scale environment, substructure, and redshift-space effects, making this a hitherto unexplored probe of both primordial cosmology and galaxy evolution. Using convenient summary statistics – the width, median, and a low percentile of the VVF as functions of average tracer number density – we explore these effects for tracer populations in a suite of N-body simulations of a range of dark matter models. Our summary statistics sensitively probe primordial features such as small-scale oscillations in the initial matter power spectrum (as arise in models involving collisional effects in the dark sector), while being largely insensitive to a truncation of initial power (as in warm dark matter models). For vanilla cold dark matter (CDM) cosmologies, the summary statistics display strong evolution and redshift-space effects, and are also sensitive to cosmological parameter values for realistic tracer samples. Comparing the VVF of galaxies in the Galaxies & Mass Assembly (GAMA) survey with that of abundance-matched CDM (sub)haloes tentatively reveals environmental effects in GAMA beyond halo mass (modulo unmodelled satellite properties). Our exploratory analysis thus paves the way for using the VVF as a new probe of galaxy evolution physics as well as the nature of dark matter and dark energy.

Boxplots are a useful enhancement to the traditional summary statistics such as the mean and variance. Based on the median and other percentiles of the data distribution, they provide more information in a graphic format which is convenient for interpreting the nature of one or several data sets Use of boxplots is illustrated with three common types of forestry data: 1) tree diameter distributions, 2) tree volume function residuals, and 3) forest inventory summaries.
