Gómez-RosAbstractThis paper reports on the thermoluminescence (TL) emission (from 250 to 500 nm) of a 10 Gy irradiated natural Na-rich aluminosilicate from Minas Gerais (Brazil), previously characterized by Raman spectroscopy and differential thermal analysis techniques. 3D-TL spectrum of the analyzed sample displays a complex glow curves with five different emissions bands peaked at 290, 380, 420, 460 and 500 nm that could be associated with structural and point defects. The UV-blue emission bands have the following characteristics: (i) the 290 nm waveband could be due to defects-sites by the presence of Na ions; (ii) the 380 nm band, caused by intrinsic defects in the lattice (i.e. Non-Bridging Oxygen Hole Centers (NBOHCs), [AlO4]o centres, alkali planar defects and Oxygen Defect Centers (ODCs), among others); (iii) the 420 nm waveband, linked to the recombination on a centre formed from a hole-oxygen atom adjacent to two aluminum atoms (Al-O-Al) and Al-O-Si complexes; (iv) the 460 nm band, associated with the presence of Ti4+ in the plagiclase crystal lattice. The green waveband could be linked to de-excitation of Mn2+ ions. The estimation of the activation energy (Ea) from the 10 Gy-induced TL glow curves analyzed by means of the initial rise method display linear regressions with acceptable r coefficients...
Conclusions: Although persons with AD are often collectively considered as expensive patient group, there is large temporal and inter-individual variation in belonging to the highest decile of hospitalization and/or medication costs. It would be important to assess whether hospitalization rate could be decreased by, e.g., comprehensive outpatient care with more efficient management of comorbidities. In addition, other interventions that could decrease hospitalization rate in persons with dementia should be studied further in this context. Key messages Persons with AD had large individual fluctuation in hospital care costs ...
Conclusion and Significance: Understanding the participants' lived experiences raised consciousness of the injustices that exist before and during rehabilitation which uncovered pointers to improve local substance addiction rehabilitation programs: use of occupation-based social participation interventions, limitation of occupational therapy services due to lack of human resources reinforcing interprofessional collaboration, a participatory approach is essential in discussing and addressing injustices, and deliberate use of political activities of daily living.

ConclusionDespite the use of AEDs in the majority of patients, only one-third were seizure-free. Other challenges included polypharmacy, the use of valproate in women, and variable adherence. This points to a need for closer follow-up in patients with JME.Graphical abstract
