Background: Parkinson's disease is now one of the fastest-growing neurodegenerative disorders in the developed world, with an increasing prevalence and associated socioeconomic costs. Progression of the disease leads to a gradual deterioration in patients' quality of life, despite optimal treatment, and both medical and societal needs increase, often with the assistance of paid and/or unpaid caregivers.

Objective: We aimed to quantify the incremental economic burden of Parkinson's disease by disease severity in a real-world setting across differing geographic regions.

Introduction: Device-aided therapy may improve the quality of life (QoL) for people with advanced Parkinson's disease (PD) and poorly controlled symptoms with oral therapy. MANAGE-PD is a validated tool classifying patients based on symptom control and advanced treatment eligibility. This study focused on patient/caregiver reported outcomes and healthcare resource utilization among patients grouped by MANAGE-PD categories.

Background: While immediate benefits of levodopa-carbidopa intestinal gel (LCIG) are evident in patients with Parkinson's disease (PD), long-term LCIG effects require further study.

Objectives: We explored long-term LCIG on motor symptoms, nonmotor symptoms (NMS), and LCIG treatment settings in patients with advanced PD (APD).

Methods: Data were obtained (medical records and patient visit) from COSMOS, a multinational, retrospective, cross-sectional post-marketing observational study in patients with APD.

Background: Caring for a partner or family member with Parkinson's disease (PD) negatively affects the caregiver's own physical and emotional well-being, especially those caring for people with advanced PD (APD). This study was designed to examine the impact of APD on caregiver perceived burden, quality of life (QoL), and health status.

Methods: Dyads of people with PD and their primary caregivers were identified from the Adelphi Parkinson's Disease Specific Program (DSP™) using real-world data from the United States, Japan and five European countries.

Introduction: Research comparing levodopa/carbidopa intestinal gel (LCIG), deep brain stimulation (DBS), and continuous subcutaneous apomorphine infusion (CSAI) for advanced Parkinson's disease (PD) is lacking. This network meta-analysis (NMA) assessed the comparative effectiveness of LCIG, DBS, CSAI and best medical therapy (BMT) in reducing off-time and improving quality of life (QoL) in patients with advanced PD.

Methods: A systematic literature review was conducted for randomized controlled trials (RCTs), observational and interventional studies from January 2003 to September 2019.

Introduction: Patients with advanced Parkinson's disease (APD) commonly experience motor and nonmotor symptoms (NMS) associated with functional limitations and decreased quality of life. We compared motor and nonmotor outcomes in patients with APD receiving 24- versus 16-h levodopa-carbidopa intestinal gel (LCIG).

Methods: Data from COSMOS, a large, real-world, retrospective and cross-sectional, observational study on LCIG and comedication in APD were obtained from medical records and a single patient visit for patients receiving 24- and 16-h LCIG infusion.

Background: In advanced Parkinson's disease (PD), dyskinesias and non-motor symptoms such as sleep dysfunction can significantly impair quality of life, and high-quality management is an unmet need.

Objective: To analyze changes in dyskinesia and non-motor symptoms (including sleep) among studies with levodopa-carbidopa intestinal gel (LCIG) in patients with advanced PD.

Methods: A comprehensive literature review identified relevant studies examining LCIG efficacy.

Objectives: In the absence of widely accepted criteria, determining when a patient with Parkinson's disease (PD) may benefit from more advanced treatments such as device-aided therapy (DAT) so far remains a matter of physician judgment. This analysis investigates how classification of PD varies across countries relative to measures of disease severity.

Materials And Methods: The OBSERVational, cross-sEctional PD (OBSERVE-PD) study included consecutive patients with PD at centers that offer DATs in 18 countries.

Introduction: Standardized and validated criteria to define advanced Parkinson's disease (PD) or identify patient eligibility for device-aided therapy are needed. This study assessed the psychometric properties of clinical indicators of advanced PD and eligibility for device-aided therapy in a large population.

Methods: This retrospective analysis of the Adelphi Parkinson's Disease Specific Programme collected data from device-aided therapy-naïve people with PD in G7 countries.

The aim of the COmedication Study assessing Mono- and cOmbination therapy with levodopa-carbidopa inteStinal gel (COSMOS) was to assess the use of levodopa/carbidopa intestinal gel (LCIG) as monotherapy in patients with advanced Parkinson's disease (APD) in routine clinical practice. COSMOS was an international observational study with one cross-sectional visit and retrospective data collection. In Romania, 95 adult patients with APD on LCIG treatment for at least 12 months were enrolled and stratified according to their LCIG therapy after 12 months: monotherapy (without any add-on PD medication), monotherapy with night PD medication and LCIG + add-on medication.

Introduction: Making Informed Decisions to Aid Timely Management of Parkinson's Disease (MANAGE-PD) is a clinician-reported tool designed to facilitate timely identification and management of patients with advancing Parkinson's disease (PD) with suboptimal symptom control while on standard therapy. The objective of this study was to evaluate the validity and clinical value of the tool.

Methods: Driven by structured inputs from a steering committee and panel of PD experts, the tool was developed to classify patients into 3 categories.

Aim: To describe the safety and efficacy of patterned laser trabeculoplasty (PLT) as an adjunctive treatment in primary open angle glaucoma (POAG) and ocular hypertension (OHT) after 18-month follow-up in Hispanic population.

Methods: A single-center, retrospective study was conducted. All patients with OHT or POAG undergoing PLT from June 2016 to August 2016 were included in the study.

Background: Levodopa-carbidopa intestinal gel (LCIG) is administered directly to the small intestine of patients with advanced Parkinson's disease (APD) to help maintain stable plasma levodopa levels.

Objective: The objective of this study was to investigate the effect of LCIG in reducing polypharmacy for the treatment of APD.

Methods: The COmedication Study assessing Mono- and cOmbination therapy with levodopa-carbidopa inteStinal gel (COSMOS) is a large, real-world, multinational observational study investigating comedication use with LCIG.

Background: There are currently no standard diagnostic criteria for characterizing advanced Parkinson's disease (APD) in clinical practice, a critical component in determining ongoing clinical care and therapeutic strategies, including transitioning to device-aided treatment. The goal of this analysis was to determine the proportion of APD vs. non-advanced PD (non-APD) patients attending specialist PD clinics and to demonstrate the clinical burden of APD.

Introduction: Continuous delivery of levodopa-carbidopa intestinal gel (LCIG) by percutaneous endoscopic gastrojejunostomy (PEG-J) in advanced Parkinson's disease (PD) patients reduces variability in plasma levels, providing better control of motor fluctuations ("on" and "off" states). The MONOTREAT study assessed the effect of LCIG on activities of daily living, motor and non-motor symptoms, and quality of life in advanced PD patients.

Methods: This prospective, observational study included patients with advanced, levodopa-responsive PD with either 2-4 h of "off" time or 2 h of dyskinesia daily.
