Efficacy of a multidisciplinary treatment program on one-year outcomes of individuals with Parkinson's disease

Motor improvement after deep brain stimulation (DBS) in the subthalamic nucleus (STN) may vary substantially between Parkinson’s disease (PD) patients. Research into the relation between improvement and active contact location requires a correction for anatomical variation. We studied the relation between active contact location relative to the neurophysiological STN, estimated by the intraoperative microelectrode recordings (MER-based STN), and contralateral motor improvement after one year. A generic STN shape was transformed to fit onto the stereotactically defined MER sites. The location of 43 electrodes (26 patients), derived from MRI-fused CT images, was expressed relative to this patient-specific MER-based STN. Using regression analyses, the relation between contact location and motor improvement was studied. The regression model that predicts motor improvement based on levodopa effect alone was significantly improved by adding the one-year active contact coordinates (R2 change = 0.176, p = 0.014). In the combined prediction model (adjusted R2 = 0.389, p < 0.001), the largest contribution was made by the mediolateral location of the active contact (standardized beta = 0.490, p = 0.002). With the MER-based STN as a reference, we were able to find a significant relation between active contact location and motor improvement. MER-based STN modeling can be used to complement imaging-based STN models in the application of DBS.

Abstract Aim People experiencing homelessness are often excluded from treatment programs for alcohol use disorder (AUD). The goal of this study was to describe the impact of a multidisciplinary treatment program on alcohol consumption and social reintegration in individuals with AUD experiencing homelessness. Methods Thirty-one individuals with AUD experiencing homelessness were admitted to an inpatient unit for 5–6 days for clinical evaluation and to treat potential alcohol withdrawal syndrome. A group of volunteers, in collaboration with the Community of Sant’Egidio, provided social support aimed to reintegrate patients. After inpatient discharge, all patients were followed as outpatients. Alcohol intake (number drinks/day), craving and clinical evaluation were assessed at each outpatient visit. Biological markers of alcohol use were evaluated at enrollment (T0), at 6 months (T1) and 12 months (T2). Results Compared with T0, patients at T1 showed a significant reduction in alcohol consumption [10 (3–24) vs 2 (0–10); P = 0.015] and in γ-glutamyl-transpeptidase [187 (78–365) vs 98 (74–254); P = 0.0021]. The reduction in alcohol intake was more pronounced in patients with any housing condition [10 (3–20) vs 1 (0–8); P = 0.008]. Similarly, compared with T0, patients at T2 showed significant reduction in alcohol consumption [10 (3–24) vs 0 (0–15); P = 0.001], more pronounced in patients with any housing condition [10 (3–20) vs 0 (0–2); P = 0.006]. Moreover, at T2 patients showed a significant reduction in γ-glutamyl-transpeptidase [187 (78–365) vs 97 (74–189); P = 0.002] and in mean cell volume [100.2 (95–103.6) vs 98.3 (95–102); P = 0.042]. Conclusion Patients experiencing homelessness may benefit from a multidisciplinary treatment program for AUD. Strategies able to facilitate and support their social reintegration and housing can improve treatment outcomes.
