Illness cognitions in head and neck squamous cell carcinoma: predicting quality of life outcome

Goals of work: This paper presents an observational study of the longitudinal effects of cancer treatment on quality of life (QoL) in patients treated for head and neck squamous cell carcinoma (HNSCC), and evaluated the contribution of patients' baseline illness cognitions to the prediction of QoL 2 years after diagnosis. Patients and methods: One hundred seventy-seven patients eligible for primary treatment for HNSCC completed the Illness Perception Questionnaire-Revised at baseline and the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire-30 at baseline, at 1-year and 2-year follow-ups. Main results Compared to baseline, patients reported better emotional functioning at both follow-ups (p<0.001), worse social functioning at 12 months (p<0.05), and better global health

Species differentiation and gene flow in the Blackbutts (Genus Eucalyptus subgenus Eucalyptus section Pseudophloius)

The significance of the taxonomic distinction of two species of Blackbutt was studied by analysing patterns of genetic (microsatellite markers; n = 13) and phenetic (capsule morphology) differentiation. Analysis of genetic structure using a Bayesian modelling approach on range-wide samples of both taxa (n = 457) showed the major division was within the more widely distributed species, Eucalyptus pilularis, and not aligned with taxonomy. Comparisons of intra- and inter-taxon genetic differentiation in paired-samples of taxa from each of four locations spanning the distribution of the more restricted E. pyrocarpa, showed that around twice as much variation was found among locations within taxa, than between taxa. Despite the lack of differentiation at effectively neutral microsatellite markers, significant phenetic differences (including capsule size) were evident between taxa at most sites. A landscape mosaic of taxa, coincident with changes in elevation, vegetation and soil types, suggested some phenetic differences were probably adaptive and spatial differentiation was stabilised by environmental factors. An absence of morphological intermediates and a lack of correlation in the rankings of locus inter-taxon differentiation (PhiBT) across locations, was consistent with parapatric origins for E. pyrocarpa. We conclude the taxa are at the lower end of the speciation spectrum and might best be viewed as ecotypes, divergent in evolutionary potential, but with genomes broadly permeable to inter-taxa gene flow. Gene exchange between plantings of E. pilularis and nearby E. pyrocarpa forest is likely as the two taxa appear to have few barriers to reproduction

Imitation Assessment and Its Utility to the Diagnosis of Autism: Evidence from Consecutive Clinical Preschool Referrals for Suspected Autism

The present study sought to examine imitation difficulties as a risk factor for autism. Imitation aptitude was examined in 86 preschoolers suspected of autism (1.9-4.5 years) using the Preschool Imitation and Praxis Scale (PIPS). Differences between imitation, language, motor age-equivalents and nonverbal mental age were used to predict the diagnosis of autism. Multidisciplinary team diagnoses and ADOS-G classifications were used to differentiate children with autism spectrum disorders and non-spectrum developmental disorders. Two factors were found to be significantly associated with autism using simple logistic regression analyses: procedural imitation delay and receptive language delay. In a multivariable setting, only procedural imitation delay remained a significant predictor of autism. Results are new to the literature and require replications
