Objectives: Dance as a non-pharmacological therapy is commonly used in dementia care, although the evidence of its effects remains unclear. This study systematically reviewed the effects of dance interventions on neuropsychiatric symptoms (NPS) in people living with dementia. To systematically identify and evaluate dance interventions, a standardized terminology for Dance-Specific Activity (DSA) is proposed., Methods: Literature search was conducted on electronic databases until April 30 th 2021. Studies were included when they quantified the effects of DSA on NPS in people with clinical diagnosis of dementia. Included studies were analyzed in detail for NPS. Study quality was assessed by PEDro scale (German version)., Results: 4 studies were included. The studies differed in study design, intervention protocols, dance styles, or measurement tools, and were generally of low study quality. Two trials showed improvements in NPS and 2 trials showed no exacerbation of NPS after DSA., Conclusions: The results of the 4 available trials indicate a positive tendency towards the effects of DSA, but considering the limitations of the few available studies, a clear statement about the effects of DSA is not possible yet. Based on the included trials, the following implications for clinical research and routine care can be derived: (1) DSA seems to be a practical terminology for identifying dance interventions (2) DSA seems to be a safe intervention for people living with dementia. (3) Different dance styles can be used. (4) DSA approaches should be better structured by differentiating between the domains type, content, intention, and protocol of the intervention.

Purpose: To further investigate the safety and performance of the Passeo-18 Lux drug-coated balloon (DCB) for the treatment of atherosclerotic infrainguinal disease under real-world conditions. Materials and Methods: BIOLUX P-III is an international, prospective, observational registry ( ClinicalTrials.gov identifier NCT02276313) conducted at 41 centers in Europe, Asia, and Australia with follow-up visits at 6, 12, and 24 months. Of 700 patients (mean age 70.0±10.2 years; 439 men) with 863 lesions in the all-comers cohort, 330 (47.1%) patients had diabetes and 234 (37.7%) had chronic limb-threatening ischemia. The majority (79.3%) of lesions were in the femoropopliteal segment; of all lesions, 645 (74.9%) were calcified and 99 (11.5%) had in-stent restenosis (ISR). The mean lesion length was 84.7±73.3 mm. The primary clinical endpoint was major adverse events (MAEs) within 6 months, a composite of device- and procedure-related mortality through 30 days, major target limb amputation, and clinically-driven target lesion revascularization (TLR). The primary performance endpoint was clinically-driven TLR within 12 months. Results: At 6 and 12 months, freedom from MAEs was 94.0% and 89.5% in the all-comers cohort: 95.0% and 91.2% in the femoropopliteal group and 95.3% and 88.0% in the ISR subgroup, respectively. Freedom from clinically-driven TLR at 12 months was 93.1% in the all-comers cohort, 93.9% in the femoropopliteal lesions, and 89.4% for ISR lesions. All-cause mortality was 6.1% in the all-comers cohort: 5.9% in both the femoropopliteal and ISR subgroups. There were no device- or procedure-related deaths at up to 12 months. The Rutherford category improved in >80% of all subgroups at 12 months. Conclusion: In a real-world patient population, the safety and performance of the Passeo-18 Lux DCB for the treatment of atherosclerotic infrainguinal lesions are maintained, with good performance outcomes and low complication rates at 12 months.

Purpose: To investigate the efficacy and sustainability of drug-coated balloon (DCB) treatment of femoropopliteal in-stent restenosis (ISR). Materials and Methods: An investigator-initiated, prospective, multicenter, 1:1 randomized study enrolled 88 patients for treatment of ISR with DCB (n=47; mean age 68.3±9.6 years; 26 men) or uncoated balloon (n=41; mean age 67.6±10.2 years; 26 men) angioplasty ( ClinicalTrials.gov identifier NCT01594684). Additionally, the protocol provided for an observational arm composed of patients from either randomized arm who experienced recurrent ISR ≥30 days after the index treatment. Redo treatment consisted of 2 DCBs sequentially inflated at the same location (double dose therapy). The majority of patients (66, 78%) had Rutherford category 3 ischemia. The mean lesion length was 140 mm; a third (27, 31%) were total occlusions. The primary endpoint was angiographic late lumen loss (LLL) at 6 months evaluated by an independent core laboratory. Results: Twenty-two patients (7 DCB +15 uncoated) were treated for recurrence with fully overlapping double DCB angioplasty. Six-month LLL was lower after DCB (0.34±1.12 mm) treatment than after angioplasty with an uncoated balloon (1.58±1.10 mm, p<0.001). At the 12-month follow-up, target lesion revascularization (TLR) was performed in 18 (49%) of 37 patients in the uncoated group, 6 (14%) of 43 patients in the single-dose DCB group (p=0.001), and no patients from the recurrent ISR group. At ~2 years after treatment, a remarkable number (14/27, 52%) of TLRs were recorded in the single-dose DCB group. Conclusion: Treatment with DCBs resulted in significantly less 6-month LLL and fewer TLRs up to 24 months than treatment with uncoated balloons. The double dose for treating recurrent ISR did not cause recognizable adverse events or require TLR up to 24 months.
