About 20.0% died at median age of 12.5 years and 9.5 years after the onset in early-onset group. About 2.0% of the late-onset patients died during the follow-up. A total of 176 mutations were identified. Patients carrying two null alleles in PANK2 showed significantly earlier age of disease onset and progressed more rapidly to loss of independent ambulance. CONCLUSIONS This study provided a comprehensive review on the natural history and genotype of 248 patients with PKAN. The results will serve as a historical control data for future clinical trial on PKAN. © 2020 The Authors. CNS Neuroscience & Therapeutics published by John Wiley & Sons Ltd.Catecholamines play important roles in biology but their structural similarity makes it challenging to construct synthetic receptors with selective binding. A combination of covalent and noncovalent binding groups in the hydrophobic core of water-soluble nanoparticles enabled them to recognize dopamine and epinephrine with an association constant (Ka ) of 3-4×104  M-1 in water, an order of magnitude higher than those of previously reported synthetic hosts. In addition, minute structural changes among analogues were detected including the addition or removal of a single hydroxyl or methyl group. © 2020 Wiley-VCH Verlag GmbH & Co.

This two-step 'how to guide' provides the reviewer with a recipe for effectively evaluating trauma radiographs for traumatic pathology and succinctly documenting the findings. Step 1 is a systematic search of the radiograph soft tissues, bones, alignment of joints and satisfaction of search (SBASS). Utilising SBASS increases reviewer confidence in identifying traumatic pathology of the appendicular and axial skeleton. Step 2 is a streamlined communication model for the documentation of pathological findings. The WWW acronym (What is it? Where is it? What is it doing?) can be adapted to describe simple or complex traumatic pathology. © 2020 The Authors.

The aim of this study was to investigate whether parotid glands should be treated as separate or combined structures when using knowledge-based planning (KBP) to create oropharyngeal plans, based on the dose they receive. METHOD Two separate RapidPlan (RP) models were created using the same 70 radical oropharyngeal patients. The 'separated model' divided the parotids into ipsilateral and contralateral structures. The 'combined model' did not separate the parotids. The models were independently validated using 20 patients not included in the models. The same dose constraints and priorities were applied to planning target volumes (PTVs) and organs at risk (OARs) for all plans. An auto-generated line objective and priority was applied in both models, with parotid mean dose and V50 doses evaluated and compared. RESULTS Plans optimised using the combined model resulted in lower ipsilateral mean doses and lower V50 doses in 80% and 75% of cases, respectively. Fifty-five per cent of plans produced lower mean doses for the contralateral parotid when optimised using the combined model, while lower V50 doses were evenly split between the models. CONCLUSION Combining the data for both parotids into one RP model resulted in better ipsilateral parotid sparing. Results also suggest that a combined parotid model will spare dose to the contralateral parotid; however, further investigation is required to confirm these results. © 2020 The Authors.

METHODS This prospective, longitudinal study comprised 28 eyes of 16 patients with open-angle glaucoma. Baseline data were obtained from oxygen inhalation testing, including laser speckle flowgraphy measurements of tissue-area mean blur rate (MT), which represents ONH tissue blood flow, and the mean percentage change in MT (MT-change). Follow-up data were collected for at least 2 years, including at least 5 reliable visual field tests. The average total deviation (TD) was calculated in each sector of the Garway-Heath map; in this study, superior, central and inferior TD corresponded to inferior, temporal and superior MT or MT-change, respectively. MT and MT-change in three sectors per eye were included as explanatory variables in a multivariable linear mixed-effects model, with TD slope set as the response variable. RESULTS At baseline, lower MT and higher diastolic blood pressure were associated with lower MT-change (p  less then  0.05). Additionally, MT-change significantly contributed to TD slope in the corresponding sectors (β = 0.41, p = 0.01). CONCLUSIONS Weaker ONH tissue vasoreactivity to systemic hyperoxia, assessed with laser speckle flowgraphy, was associated with lower baseline ONH tissue blood flow, higher diastolic blood pressure and rapid visual field defect progression. Laser speckle flowgraphy variables during oxygen provocation testing may represent potentially useful predictive biomarkers of glaucoma progression. © 2020 Acta Ophthalmologica Scandinavica Foundation.

METHOD Tear and aqueous humour samples were collected from 29 healthy controls and 27 POAG patients. Twenty-seven inflammatory cytokines were analysed interleukin (IL)-1β, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL9, IL-10, IL-12, IL-13, IL-15, IL-17, eotaxin, fibroblast growth factor (FGF) basic, granulocyte colony-stimulating factor, granulocyte-monocyte colony-stimulating factor, interferon (IFN)-γ, interferon gamma-induced protein, monocyte chemo-attractant protein-1, macrophage inflammatory protein (MIP)-1α, MIP-1β, platelet-derived growth factor, regulated on activation normal T cell expressed and secreted, tumour necrosis factor (TNF)-α and vascular endothelial growth factor (VEGF). RESULTS In tear samples of glaucoma patients, an increase in IL-4, IL-12, IL-15, FGF-basic and VEGF was observed, as well as a decrease in MIP-1a relative to the control group (p  less then  0.
