    Supporting pupils with autism spectrum disorder (ASD) in mainstream schools is a challenging task. This paper proposes a professional development framework for EPs to consider when supporting the development of specialist ASD staff. The framework focuses on training content, educator characteristics and organisational elements. Nine mainstream schools developing additional provision to support children with ASD and Specific Language Impairment (SLI) participated in the research. Specialist staff were provided with training and took part in follow up interviews about their developing practice. A pre-post questionnaire of participants (N = 30) attending the specialist training is supplemented with longitudinal interview data from specialist staff (N = 20). A paired sample t-test of questionnaire data showed that staff self-efficacy significantly increased pre to post training with a large effect size(0.61) and thematic analysis of interviews provided evidence of sustained professional development over time underpinned by supportive organisational factors

    Assessing the life cycle environmental impacts of titania nanoparticle production by continuous flow solvo/hydrothermal synthesis

    Continuous-flow hydrothermal and solvothermal syntheses offer substantial advantages over conventional processes, producing high quality materials from a wide range of precursors. In this study, we evaluate the “cradle-to-gate” life cycle environmental impacts of alternative titanium dioxide (TiO₂) nanoparticle production parameters, considering a range of operational conditions, precursors, material properties and production capacities. A detailed characterisation of the nano-TiO₂ products allows us, for the first time, to link key nanoparticle characteristics to production parameters and environmental impacts, providing a useful foundation for future studies evaluating nano-TiO₂ applications. Five different titanium precursors are considered, ranging from simple inorganic precursors, like titanium oxysulphate (TiOS), to complex organic precursors such as titanium bis(ammonium-lactato)dihydroxide (TiBALD). Synthesis at the laboratory scale is used to determine the yield, size distribution, crystallinity and phase of the nanoparticles. The specifications and operating experience of a full scale plant (>1000 t per year) are used to estimate the mass and energy inputs of industrial scale production for the life cycle assessment. Overall, higher process temperatures are linked to larger, more crystalline nanoparticles and higher conversion rates. Precursor selection also influences nano-TiO₂ properties: production from TiOS results in the largest particle sizes, while TiBALD achieves the smallest particles and narrowest size distribution. Precursor selection is the main factor in determining cradle-to-gate environmental impacts (>80% in some cases), due to the production impact of complex organic precursors. Nano-TiO2 production from TiOS shows the lowest global warming potential (GWP) (<12 kg CO₂-eq. per kg TiO₂) and cumulative energy demand (CED) (<149 MJ kg¯¹ TiO₂) due to the low environmental impact of the precursor, the use of water as a solvent and its high yield even at lower temperatures. Conversely, the TiBALD precursor shows the highest impact (86 kg CO₂-eq. per kg TiO₂ and 1952 MJ kg¯¹ TiO₂) due to the need for additional post-synthesis steps and complexity of precursor manufacturing. The main purpose of this study is not a direct comparison of the environmental impacts of TiO₂ nanoparticles manufactured utilizing various precursors under different conditions, but to provide an essential foundation for future work evaluating potential applications of nano-TiO₂ and their life cycle environmental impacts

    Factors determining the clinical significance of dipeptidyl peptidase-4 inhibitors in the treatment of elderly patients with type 2 diabetes mellitus

    Elderly patients with diabetes type 2 represent complex and heterogeneous group with different diabetes complications and comorbidity, polypharmacy, functional and cognitive state. Each of those factors should be taken into account to choose the best glycemic targets as well as the most tailored treatment so that it is necessary for endocrinologist to perform geriatric assessment. The most favorable antidiabetic drugs for elderly are safe in terms of hypoglycemia and cardiovascular risks, can be used irrespective of kidney function, do not affect weight or bone mineral density, and are available in fixed combinations with other drugs. Dipeptidyl pepti-dase-4 (DPP-4) inhibitors meet all these requirements with low adverse events rate. Interdisciplinary approach, close interaction with patient and his relatives and considerations for both intensification and deprescribing are keys to successful treatment in this patient subgroup. Cardiovascular events are the most common cause of death and hypoglycemia is highly unfavorable in elderly because it can lead to falls, life-threatening arrhythmias, and cognitive impairment. So deprescribing in elderly with diabetes should be primarily aimed at minimizing of cardiovascular events and severe hypoglycemia risks. For this purpose, it is considered to the reject use of sulfonylureas, glinides, insulins in favor of safer ones (metformin, GLP-1 receptor agonists, SGLT-2 inhibitors, DPP-4 inhibitors)
