Introduction Treatment adjustments in Parkinson's disease (PD) are in part dependent on motor assessments. The aim of this study was to evaluate the cost-effectiveness of home-based motor monitoring plus standard in-office visits versus in-office visits alone in patients with advanced PD. Methods The procedures consisted of a prospective, one-year follow-up, randomized, case-control study. A total of 40 patients with advanced PD were randomized into two groups: 20 patients underwent home-based motor monitoring by using wireless motion sensor technology, while the other 20 patients had in-office visits. Motor and non-motor symptom severities, quality of life, neuropsychiatric symptoms, and comorbidities were assessed every four months. Direct costs were assessed using a standardized questionnaire. Cost-effectiveness was assessed using the incremental cost-effectiveness ratio (ICER). Results Both groups of PD patients were largely comparable in their clinical and demographic variables at baseline; however, there were more participants using levodopa-carbidopa intestinal gel in the home-based motor monitoring group. There was a trend for lower Unified Parkinson's Disease Rating Scale functional status (UPDRS II) scores in the patients monitored at home compared to the standard clinical follow-up ( p = 0.06). However, UPDRS parts I, III, IV and quality-adjusted life-years scores were similar between both groups. Home-based motor monitoring was cost-effective in terms of improvement of functional status, motor severity, and motor complications (UPDRS II, III; IV subscales), with an ICER/UPDRS ranging from €126.72 to €701.31, respectively. Discussion Home-based motor monitoring is a tool which collects cost-effective clinical information and helps augment health care for patients with advanced PD.

Background: Little is known about the impact of nutrition status on Huntington's disease (HD) severity. Objective: To analyze the association of nutritional factors with HD severity. Methods: Observational, cross-sectional, national multicenter study. Participants were selected from a Spanish cohort of patients who participate in the European Huntington Disease Network (EHDN). The frequency of food consumption, caloric and nutrients intake in patients with HD were assessed using validated questionnaires for the Spanish population, and calculated using Alimentación and Salud, version 2.0, and the Spanish Dietary Recommended Intakes were used as the gold standard. Disease severity was assessed using the Unified HD Rating Scale (UHDRS) and Total Functional Capacity (TFC). Logistic regression models were performed using the TFC as the dependent variable, and the macro-micronutrients as the independent variables, adjusted for age, gender, education, physical activity, and intake of supplements. Results: Two hundred and twenty four patients with HD were included (59% women), mean age of 47.41 ± 14.26 years, median TFC 9 (3-13), median UHDRS motor score of 33.5 (3.75-56), 75.8% with normal-high caloric intake, 55.4% normal BMI, and 54.4% with medium-high adherence to the Mediterranean diet. Compared to patients with mild-moderate HD, patients with severe HD had higher caloric intake (p = 0.02), and similar BMI (p = 0.33). Advanced HD was associated with higher intake of water-soluble vitamins (OR = 2.08; 95% CI = 1.12-3.85, p = 0.02), and minerals (OR = 1.86; 95% CI = 1.09-3.19, p = 0.02). Conclusions and relevance: An adequate dietary intake prevents against weight loss in patients with advanced HD, but it is not associated with better functional state.
