Aims. This study assesses the impact of using an AP-system at home on fear of hypoglycaemia. In addition, satisfaction and acceptance of the new technology are evaluated. Methods. In a multicentre, multinational study of 75 patients using the MD-Logic AP during four consecutive nights in home setting 59 of them (aged 10–54 years, 54% male, HbA1c 7.89 ± 0.69% [62.72 ± 7.51 mmol/mol], diabetes duration 11.6 ± 8.4 yrs) answered standardized questionnaires (HFS, adapted TAM, and AP satisfaction) before and after using the AP. Results. After experiencing the AP in home setting worries of hypoglycaemia were significantly reduced (before 1.04 ± 0.53 versus after 0.90 ± 0.63; P = 0.017). Perceived ease of use as a measure of acceptance with the AP significantly increased after personal experience (before 4.64 ± 0.94 versus after 5.06 ± 1.09; P = 0.002). The overall satisfaction mean score after using the AP was 3.02 ± 0.54 (range 0–4), demonstrating a high level of satisfaction with this technology. Conclusions. The four-night home-based experience of using MD Logic AP was associated with reduced worries of hypoglycaemia, high level of satisfaction, and increased perceived ease of use of the new technology in children, adolescents, and adults.

Neuronal intranuclear inclusion disease (NIID) is a multisystem neurodegenerative disorder characterized by large intranuclear aggregates in neurons of the central and peripheral nervous system. These ubiquitinated intranuclear inclusions are morphologically similar to the intraneuronal aggregates that have been identified in the CAG/polyglutamine expansion diseases. As rare aggregates in NIID contain a polyglutamine epitope, we further investigated the relationship between this disease and the CAG/polyglutamine expansion diseases. Here, we show that ataxin 1 and ataxin 3 proteins are recruited into aggregates in NIID in the absence of a CAG expansion in the SCA1 and SCA3 genes. These data support an association of NIID with the polyglutamine disorders and provide evidence of in vivo recruitment of proteins with polyglutamine tracts into intraneuronal aggregates.
