 INTRODUCTION The aim of this study was to examine the hospital variation in neoadjuvant treatment of rectal cancer according to the different risk groups (low-, intermediate- and high-risk) and evaluate the influence on survival. MATERIALS AND METHODS Patients with non-metastasized rectal cancer diagnosed between 2009 and 2016 were selected from the Netherlands Cancer Registry. The observed and case-mix adjusted distribution of the different neoadjuvant treatment schemes (none, radiotherapy (RT), chemoradiotherapy (CRT)) by hospital of diagnosis were generated for each risk group in the cohorts before and after the national guideline update of 2014. RESULTS A total of 25,306 patients were included and after case-mix adjustment, hospital of diagnosis was found to have a significant impact on neoadjuvant treatment administration in each of the three risk groups (p  less then  0.001). Overall survival was however not influenced, except for the high-risk group where hospitals with highest rates of CRT were associated with a better 5-years overall survival (HR 0.79; p = 0.03). After guideline revision, the rate of patients in the low-risk group who did not undergo RT increased from a median of 30.8% to 90.5% (p  less then  0.001). CONCLUSION Although a significant change in treatment was observed after revision of the national guidelines, a wide range of hospital variation still exists in administered neoadjuvant treatment in rectal cancer patients. High-risk rectal cancer patients had a better survival when treated in hospitals with the highest rates of CRT provided. In order to minimize treatment differences, further research into the causes of this variation and implementation of regionalized MDTs may be warranted. PURPOSE Motion management is crucial in scanned proton therapy for mobile tumours. Current motion mitigation approaches rely on single 4DCTs before treatment, ignoring respiratory variability. We investigate the consequences of respiratory variations on internal target volumes (ITV) definition and motion mitigation efficacy, and propose a probabilistic ITV based on 4DMRI. MATERIALS AND METHODS Four 4DCT(MRI) datasets, each containing 40 variable cycles of synthetic 4DCTs, were generated by warping single-phase CTs of two lung patients with motion fields extracted from two 4DMRI datasets. Two-field proton treatment plans were optimised on ITVs based on different parts of the 4DCT(MRI)s. 4D dose distributions were calculated by considering variable respiratory patterns. Different probabilistic ITVs were created by incorporating the voxels covered by the CTV in at least 25%, 50%, or 75% (ITV25, ITV50, ITV75) of the cycles, and compared with the conservative ITV encompassing all possible CTV positions. RESULTS Depending on the selected planning 4DCT, ITV volumes vary up to 20%, resulting in significant variation in CTV coverage for 4D treatments. Target coverage and homogeneity improved with the conservative ITV, but was associated with significantly increased lung dose (~1%). ITV25 and ITV50 led to acceptable plan quality in most cases without lung dose increments. ITV75 best minimised lung dose, but was insufficient to ensure coverage under all motion scenarios. CONCLUSION Irregular respiration significantly affects CTV coverage when ITVs are only defined by single 4DCTs. A probabilistic ITV50 provides an adequate compromise between target coverage and lung dose for most motion and patient scenarios investigated. BACKGROUND Anhedonia, a symptom prevalent in schizophrenia patients, is thought to arise either within negative symptomatology or from secondary sources, such as depression. The common co-occurrence of these diseases complicates the assessment of anhedonia in schizophrenia. METHOD In a sample of 40 outpatients with chronic schizophrenia, we explored both the validity of the Snaith-Hamilton Pleasure Scale (SHAPS) self-report for anhedonia assessment and those factors influenced its scoring. We assessed negative symptoms using the Brief Negative Symptom Scale (BNSS), depression symptoms using the Calgary Depression Scale for Schizophrenia (CDSS) and cognitive impairment using the Brief Assessment of Cognition in Schizophrenia (BACS), before exploring associations between these scales. RESULTS The SHAPS was validated for use in schizophrenia. SHAPS scores were not associated with negative symptoms or cognitive impairment, but were linked to a single Depression symptom Hopelessness (r = 0.52, p  less then  0.001). CONCLUSIONS SHAPS scores, therefore, appear to only reflect anticipatory anhedonia arising from the affective domain. We advocate the development of multi-faceted self-report measures to more holistically assess anhedonia in schizophrenia. Puberty is the most important developmental milestone closely preceding a young adult's labor market decisions. Thus, we examine the variation in the timing of physical maturity during adolescence to isolate its association with employment and hourly wages for US young adults. Using the National Longitudinal Study of Adolescent to Adult Health data, we find an early maturity premium of about 6% for females and 8% for males, but no employment advantage, in excess of gains from height and physical attractiveness. Cognitive and personality factors significantly explain this premium for both genders, but job attributes are also important for males. INTRODUCTION Multiple acyl-coenzyme A dehydrogenase deficiency disorder (MADD) is a relatively rare disorders of lipid metabolism. This study aimed to investigate the demographic, clinical, and genetic features of MADD in Iran. METHODS Twenty-nine patients with a definite diagnosis of lipid storage myopathy were recruited. All patients were tested for mutation in the ETFDH gene, and 19 had a biallelic mutation in this gene.  https://www.selleckchem.com/ALK.html  RESULTS Of 19 patients with definite mutations, 11 (57.9%) were female, and the median age was 31 years. Twelve patients had c.1130 T > C (p.L377P) mutation in exon 10. Two patients had two novel heterozygote pathogenic variants (c.679C > T (p.P227S) in exon 6 and c.814G > A (p.G272R) in exon 7) and two patients had c.1699G > A (p.E567K) in exon 13. Before treatment, the median muscle power was 4.6 (IQR 4-4.7) that increased to 5 (IQR 5-5) after treatment (Z = -3.71, p = .000).  https://www.selleckchem.com/ALK.html  The median CK was 1848 U/l (IQR 1014-3473) before treatment, which declined to 188 U/l (IQR 117-397) after treatment (Z = -3.
