[PMID: 38745275 PMCID: PMC11092171 DOI: 10.1186/s12883-024-03649-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 04/22/2024] [Indexed: 05/16/2024] Open
Abstract
INTRODUCTION Postural balance impairment can affect the quality of life of patients with Parkinson's disease. Previous studies have described connections of the vestibular system with postural functions, suggesting a potential participation of the basal ganglia in receiving vestibular stimuli. This systematic review aims to summarize the evidence on the effectiveness of vestibular rehabilitation on postural balance in patients with Parkinson's disease. METHODS A systematic review was conducted using the electronic databases: PubMed, Embase, Scopus and PEDro. The study selection was independently conducted by two reviewers, and disagreements were evaluated by a third reviewer. The included studies had no restrictions on publication dates or languages and the last update occurred in July 2023. RESULTS From the 485 studies found in the searches, only 3 studies were deemed eligible for the systematic review involving a total of 130 participants. The Berg Balance Scale was described as the tool for evaluation of postural balance in all studies. The meta-analysis showed statistically significant results in favor of vestibular rehabilitation (MD = 5.35; 95% CI = 2.39, 8.31; P < 0.001), regardless of the stage of Parkinson's disease. Although the effect size was suggested as a useful functional gain, the analysis was done with caution, as it only included 3 randomized controlled trials. The risk of bias using the RoB-2 was considered as being of "some concern" in all studies. Furthermore, the quality of the evidence based on the Grading of Recommendations Assessment Development and Evaluation system, produced by pooling the included studies was considered very low. CONCLUSION Compared to other interventions, vestibular rehabilitation has potential to assist the postural balance of patients with Parkinson's disease. However, the very low quality of the evidence demonstrates uncertainty about the impact of this clinical practice. More robust studies are needed to confirm the benefits of this therapy in patients with Parkinson's disease. This study was prospectively registered in PROSPERO: CRD42020210185.

Effects of freezing of gait on balance in patients with Parkinson's disease. Neurol Res 2023; 45:407-414. [PMID: 36413435 DOI: 10.1080/01616412.2022.2149510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Accepted: 11/16/2022] [Indexed: 11/24/2022]
Abstract
OBJECTIVES The aim of the study was to evaluate the effects of freezing of gait (FOG) on static and dynamic balance. METHODS Twenty patients with Parkinson's disease with and without FOG [PD+FOG (68,6±6,39 years) and PD-FOG group (70,6±4,57 years)] and 10 healthy individuals (68,4±4,92 years) with similar demographic characteristics were included in the study. Balance was compared between the three groups. Balance was evaluated with clinical tests Limits of stability (LoS) and body sway were measured using the E-LINK FP3 Force Plate and the Korebalance Balance Evaluation System, which measure the balance in static and dynamic conditions. Center of pressure (COP) change and average sway velocity were evaluated with the Zebris RehaWalk system. RESULTS Total and subscale scores of the Unified Parkinson's Disease Rating Scale were significantly higher in the PD+FOG group (p<0.05). The balance test results for both groups were similar (p>0.05). The PD+FOG group performed worse on the computerized static balance tests, the COP analysis, and the dynamic balance total score than the other two groups (p<0.05). The PD+FOG group had significantly greater sustained weight deviation than the healthy controls (p<0.05). Patients with Parkinson's disease had a lower LoS in the posterior direction than healthy controls (p<0.05). DISCUSSION FOG affects the dynamic balance more negatively than the static balance. In addition, FOG reduces LoS in the posterior direction and increases body sway in the anterior-posterior direction, which can lead to falls.

Exploring the ability of strength and dexterity tests to detect hand function impairment in individuals with Parkinson's disease. Physiother Theory Pract 2023; 39:395-404. [PMID: 34895020 DOI: 10.1080/09593985.2021.2013371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/26/2023]
Abstract
BACKGROUND Parkinson's disease (PD) can affect hand function since the beginning of the motor symptoms. OBJECTIVE To compare the ability of different hand function tests to: 1) distinguish individuals with PD from healthy controls; 2) differentiate stages of the disease; and 3) indicate changes over time due to disease progression. METHODS Twenty-four individuals with PD (Hoehn and Yahr: I-III) and 24 age- and sex-matched controls performed the Jebsen-Taylor Hand Function Test (JTHFT), the Nine-Hole Peg Test (9HPT), and the maximum grip and the maximum pinch strength tests using their right and left hands. Eight individuals with PD (six females and two males) were reassessed after 18 months. The ROC analyses and Mann-Whitney U tests (for disease progression) using the average performance of the hands were done. RESULTS Individuals with PD presented worse test performances than controls, except for the writing subtest of the JTHFT and the grip strength test. The JTHFT without the writing subtest (JTHFTnoW) was the most accurate to discriminate PD from controls (AUC = 0.899; sensitivity 75% and specificity 95.8%). The 9HPT and the simulated feeding and moving large, light objects JTHFT subtests were sensitive to distinguish stages, while the 9HPT, the moving small, common objects JTHFT subtest, and the grip strength were sensitive to changes with disease progression. CONCLUSION The JTHFTnoW was highly discriminative of the hand function impairments in PD. TwoJTHFT subtests were the most sensitives to distinguish PD stages (i.e. simulated feeding JTHFT subtest) and disease progression (i.e. moving small, common objects JTHFT subtest).

Abstract
BACKGROUND Levodopa-carbidopa intestinal gel (LCIG) improves motor and non-motor symptoms in patients with advanced Parkinson's disease (aPD). OBJECTIVE To present the final 36-month efficacy and safety results from DUOGLOBE (DUOdopa/Duopa in Patients with Advanced Parkinson's Disease - a GLobal OBservational Study Evaluating Long-Term Effectiveness; NCT02611713). METHODS DUOGLOBE was an international, prospective, long-term, real-world, observational study of patients with aPD initiating LCIG in routine clinical care. The primary endpoint was change in patient-reported "Off" time to Month 36. Safety was assessed by monitoring serious adverse events (SAEs). RESULTS Significant improvements in "Off" time were maintained over 3 years (mean [SD]: -3.3 hours [3.7]; p < 0.001). There were significant improvements to Month 36 in total scores of the Unified Dyskinesia Rating Scale (-5.9 [23.7]; p = 0.044), Non-Motor Symptoms Scale (-14.3 [40.5]; p = 0.002), Parkinson's Disease Sleep Scale-2 (-5.8 [12.9]; p < 0.001), and Epworth Sleepiness Scale (-1.8 [6.0]; p = 0.008). Health-related quality of life and caregiver burden significantly improved through Months 24 and 30, respectively (Month 24, 8-item Parkinson's Disease Questionnaire Summary Index, -6.0 [22.5]; p = 0.006; Month 30, Modified Caregiver Strain Index, -2.3 [7.6]; p = 0.026). Safety was consistent with the well-established LCIG profile (SAEs: 54.9% of patients; discontinuations: 54.4%; discontinuations due to an adverse event: 27.2%). Of 106 study discontinuations, 32 patients (30.2%) continued LCIG outside the study. CONCLUSION DUOGLOBE demonstrates real-world, long-term, reductions in motor and non-motor symptoms in patients with aPD treated with LCIG.

Parkinson's Disease Symptoms Associated with Developing On-State Axial Symptoms Early after Subthalamic Deep Brain Stimulation. Diagnostics (Basel) 2022; 12:diagnostics12041001. [PMID: 35454049 PMCID: PMC9027591 DOI: 10.3390/diagnostics12041001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 04/11/2022] [Accepted: 04/13/2022] [Indexed: 11/17/2022] Open
Abstract
Background: The relationship between axial symptoms in Parkinson’s disease (PD) and subthalamic deep brain stimulation (STN-DBS) is still unclear. Purpose: We searched for particular clinical characteristics before STN-DBS linked to on-state axial problems after surgery. Methods: We retrospectively analyzed baseline motor, emotional and cognitive features from PD patients with early axial symptoms (within 4 years after STN-DBS) and late axial symptoms (after 4 years). We also considered a group of PD patients without axial symptoms for at least 4 years after surgery. Results: At baseline, early-axial PD patients (n = 28) had a higher on-state Unified Parkinson’s Disease Rating Scale III (15.0 ± 5.6 to 11.6 ± 6.2, p = 0.020), higher axial score (2.4 ± 1.8 to 0.7 ± 1.0, p < 0.001) and worse dopaminergic response (0.62 ± 0.12 to 0.70 ± 0.11, p = 0.005), than non-axial PD patients (n = 51). Early-axial PD patients had short-term recall impairment, not seen in non-axial PD (36.3 ± 7.6 to 40.3 ± 9.3, p = 0.041). These variables were similar between late-axial PD (n = 18) and non-axial PD, but late-axial PD showed worse frontal dysfunction. Conclusions: PD patients with early axial symptoms after DBS may have a significantly worse presurgical motor phenotype, poorer dopaminergic response and memory impairment. This may correspond to a more severe form of PD.

Antioxidative role of Traditional Chinese Medicine in Parkinson's disease. JOURNAL OF ETHNOPHARMACOLOGY 2022; 285:114821. [PMID: 34838943 DOI: 10.1016/j.jep.2021.114821] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 10/24/2021] [Accepted: 11/05/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Neuroprotective Traditional Chinese Medicine (TCM) has been practiced in alternative medicine from early days. TCM-derived neuroprotective compounds, such as Chrysin, Cannabidiol, Toonasinoids, and β-asaron, exert significant effectiveness's towards Parkinson's disease (PD). Further, these neuroprotective TCM showed antioxidative, anti-inflammatory, anti-tumor, anti-septic, analgesic properties. Recent research showed that the reduction in the reactive oxygen species (ROS) decreased the α-synuclein (α-syn) toxicity and enhanced the dopaminergic neuron regenerations, the main hallmarks of PD. Therefore, the neuroprotective effects of novel TCM due to its antiradical activities needed deep investigations. AIMS OF THE STUDY This review aims to enlighten the neuroprotective TCM and its components with their antioxidative properties to the scientific community for future research. METHOD The relevant information on the neuroprotective TCM was gathered from scientific databases (PubMed, Web of Science, Google Scholar, ScienceDirect, SciFinder, Wiley Online Library, ACS Publications, and CNKI). Information was also gained from MS and Ph.D. thesis, books, and online databases. The literature cited in this review dates from 2001 to June 2, 0201. RESULTS Novel therapies for PD are accessible, mostly rely on Rivastigmine and Donepezil, offers to slow down the progression of disease at an early stage but embraces lots of disadvantages. Researchers are trying to find a potential drug against PD, which is proficient at preventing or curing the disease progress, but still needed to be further identified. Oxidative insult and mitochondrial dysfunction are thought to be the main culprit of neurodegenerations. Reactive oxygen species (ROS) are the only causative agent in all interactions, leading to PD, from mitochondrial dysfunctions, α-syn aggregative toxicity, and DA neurons degenerations. It is evident from the redox balance, which seems an imperative therapeutic approach against PD and was necessary for the significant neuronal activities. CONCLUSION Our study is explaining the newly discovered TCM and their neuroprotective and antioxidative properties. But also bring up the possible treatment approaches against PD for future researchers.

Abstract
AIMS Previous studies have suggested that Helicobacter pylori (H. pylori) infections may be the cause of or worsen Parkinson's disease symptoms. In this meta-analysis, all relevant studies were reviewed to assess whether H. pylori treatment would benefit patients with Parkinson's disease. MAIN METHODS Systemically searches were carried out in MEDLINE and other popular databases. The software RevMan 5.2 was used for meta-analysis. The mean difference (MD) was used as the effect size to draw forest plots. KEY FINDINGS A total of 10 qualified studies were included. For bradykinesia, the pooled MD value of stride length was -75.76, 95% CI [-109.37, -42.15, P < 0.05]; for myotonia, the pooled MD value of torque to flex was 75.24, 95% CI [27.36, 123.13, P < 0.05]. The pooled MD value of Unified Parkinson's Disease Rating Scale (UPDRS)-III scores before and after treatment was 6.27, 95% CI [1.30, 11.24, P < 0.05], suggesting that UPDRS-III scores improved in response to H. pylori treatment. The pooled MD value of levodopa onset time (min) was 14.91, 95% CI [8.92, 20.90, P < 0.05]. SIGNIFICANCE H. pylori treatment may improve the stride length in the bradykinesia index and significantly improve UPDRS-III scores.

Abstract
OBJECTIVES To investigate the effect of aerobic exercise (AE) on functional capacity and quality of life in individuals with Parkinson's disease (PD) in the mild to moderate stages. DATA SOURCES Medline, Embase, Web of Science, The Cochrane Library, Lilacs and PEDro were searched from inception until January 2021 using the MeSH terms. STUDY SELECTION Studies conducted in individuals with PD involving AE compared to a control group were included. DATA EXTRACTION Characteristics of the studies were independently extracted by two reviewers. The PEDro scale was used to assess the methodological quality, and the level of evidence was analyzed and synthesized using the GRADE approach. DATA SYNTHESIS Of the ten studies, 411 individuals with PD were included. The level of synthesized evidence for cardiorespiratory function was low and without effect, and very low and without effect. For gait was very low and with effect for speed and stride length and without effect for cadence. For mobility was very low and with effect. For muscle strength was very low and with effect for the lower limbs as well as without effect for the upper limbs. For postural balance was very low and without effect. For quality of life was low and without effect. CONCLUSION Aerobic exercise was capable of promoting improvements in gait (walking speed and stride length), mobility, and lower limb muscle strength in individuals with PD in the mild to moderate stages. No significant improvement in quality of life was found due to the practice of AE.

Abstract
OBJECTIVE To investigate the effects of resistance exercise (RE) on body structure and function, activity, and participation in individuals with Parkinson Disease (PD) in the mild to moderate stages. DATA SOURCES Medline, Embase, Web of Science, The Cochrane Library, Lilacs, and PEDro were searched from inception until June 2020 using the terms "Parkinson Disease," "Exercise," "Resistance Training," "Muscle Strength," "Cardiorespiratory Fitness," "Postural Balance," "Gait," and "Quality of Life." STUDY SELECTION We included studies conducted in individuals with PD involving RE compared with a control group. Two independent reviewers performed the selection process based on titles, abstracts, and full-text reading. In total, 270 individuals with PD were included from 10 selected studies. DATA EXTRACTION Two reviewers independently extracted characteristics related to participants, intervention and control types, and results. The PEDro scale was used to assess the methodological quality, and the level of evidence was analyzed and synthesized using the Grading of Recommendation, Assessment, Development, and Evaluations approach. DATA SYNTHESIS The level of evidence for body structure and function was low and without effect for lower limb muscle strength; very low and with effect for upper limb muscle strength, cardiorespiratory fitness, and postural balance; and very low and without effect for flexibility after RE training. For activity, the evidence was very low and with effect for gait and very low and without effect for mobility. For participation (ie, quality of life) the evidence was very low and without effect. CONCLUSIONS Although the level of evidence was low to very low, RE was shown to promote improvements in body structure and function (upper limb muscle strength, cardiovascular function, postural balance) and activity (gait). In contrast, RE did not significantly improve participation (quality of life). However, based on the present findings, the practice of RE can be recommended for individuals with PD in the mild to moderate stages.

Characterizing Advanced Parkinson's Disease: Romanian Subanalysis from the OBSERVE-PD Study. PARKINSONS DISEASE 2021; 2021:6635618. [PMID: 33564391 PMCID: PMC7850828 DOI: 10.1155/2021/6635618] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 12/22/2020] [Accepted: 01/12/2021] [Indexed: 01/10/2023]
Abstract
OBSERVE-PD was a cross-sectional, multicountry, observational study conducted in 128 Movement Disorders Centers (MDCs) in 18 countries. Overall, the study enrolled 2615 patients. The aim was to determine the proportion of patients with advanced Parkinson's disease (APD) versus non-APD from MDCs and to uncover the clinical burden of APD, as well as a correlation between overall assessment of APD and several indicators of APD. The advanced stage of the disease and severity were assessed by investigators using their clinical judgement. Data were collected during a single visit between February 2015 and January 2016. Agreement on physician judgement of APD diagnosis and fulfillment of at least one previously established APD indicator was calculated. Motor and nonmotor symptoms (NMSs), activities of daily living, treatment complications, quality of life (QoL), conventional treatments, and device-aided therapy (DAT) eligibility were assessed. Here, country-specific results of 161 Romanian patients with PD are presented. In total, 59.0% of patients were diagnosed with APD and 78.8% met at least one APD indicator. There was only moderate agreement between clinical judgement of APD and overall fulfillment of APD indicators. All scores related to motor symptoms, NMSs, and treatment complications, as well as to QoL, showed a higher disease burden for patients with APD versus non-APD. Physicians considered 73.7% of patients with APD eligible for DAT. The majority of patients eligible for DAT (54.3%) did not receive such treatment. Our results highlight the importance of earlier recognition of APD, by combining clinical judgement with more standardized clinical tools, such as generally recognized APD criteria. However, timely diagnosis of APD alone is not enough to improve patient outcomes. Other critical factors include patient acceptance and access to appropriate treatment.

Abstract
Background Patients with advanced stage Parkinson's disease (PD) typically present with a myriad of motor and nonmotor symptoms in addition to comorbidities and, as a consequence, polypharmacy. Objective To analyze a series of cases of advanced PD in which a clinical or surgical emergency played a trigger role in the irreversible progression of landmarks of the course of the disease. Methods Data were collected during a 13-month observational period of a cohort of 230 PD patients, in 751 medical appointments. We included a total of 13 (5.65% of the total number) patients with advanced PD defined by Hoehn & Yahr (H&Y) stage ≥3 who presented with various clinical and surgical complications which, with the contribution of drug interventions, led to significant worsening of patients' overall clinical condition. Results Hip fractures and infections were the most common complications identified. As part of this scenario, most patients presented with delirium, often requiring treatment with dopamine receptor blocking agents and/or had dopaminergic treatment withdrawn. Upon reassessment after 3 months, all patients remained bed or wheel chair bound (H&Y 5) and presented significant worsening of their UPDRS part III score of at least 10 points (mean 51.5 ± 3.3; paired t-test two-tailed p < 0.0001 compared to baseline). The mean dose of levodopa at baseline was 907.7 ± 149.8 mg (600–1200) and significantly higher (paired t-test two-tailed p < 0.0001) on follow-up, 1061.5 ± 175.8 mg (700–1300). Conclusion Clinical and surgical emergencies are major determinants for a progression of PD to more advanced stages.

Abstract
Objective 5- (5 times oral levodopa tablet taken/day) 2- (2 hours of OFF time/day) 1- (1 hour/day of troublesome dyskinesia) criteria have been proposed by a Delphi expert consensus panel for diagnosing advanced Parkinson's disease (PD). The aim of the present study is to compare quality of life (QoL) in PD patients with "5-2-1 positive criteria" vs QoL in PD patients without "5-2-1 positive criteria" (defined as meeting ≥1 of the criteria). Methods This is a cross-sectional, observational, monocenter study. Three different instruments were used to assess QoL: the 39-Item Parkinson's Disease Quality of Life Questionnaire Summary Index Score (PDQ-39SI); a subjective rating of perceived QoL (PQ-10); and the EUROHIS-QOL 8-Item Index (EUROHIS-QOL8). Results From a cohort of 102 PD patients (65.4 ± 8.2 years old, 53.9% males; disease duration 4.7 ± 4.5 years), 20 (19.6%) presented positive 5-2-1 criteria: 6.9% for 5, 17.6% for 2, and 4.9% for 1. 37.5% (12/32) and 25% (5/20) of patients with motor complications and dyskinesia, respectively, presented 5-2-1 negative criteria. Both health-related (PDQ-39SI, 25.6 ± 14 vs 12.1 ± 9.2; p < 0.0001) and global QoL (PQ-10, 6.1 ± 2 vs 7.1 ± 1.3; p=0.007; EUROHIS-QOL8, 3.5 ± 0.5 vs 3.7 ± 0.4; p=0.034) were worse in patients with 5-2-1 positive criteria. Moreover, nonmotor symptoms burden (Non-Motor Symptoms Scale total score, 64.8 ± 44.8 vs 39.4 ± 35.1; p < 0.0001) and autonomy for activities of daily living (ADLS scale, 73.5 ± 13.1 vs 89.2 ± 9.3; p < 0.0001) were worse in patients with 5-2-1 positive criteria. Patient's principal caregiver's strain (Caregiver Stain Index, 4.3 ± 3 vs 1.5 ± 1.6; p < 0.0001), burden (Zarit Caregiver Burden Inventory, 28.4 ± 12.5 vs 10.9 ± 9.8; p < 0.0001), and mood (Beck Depression Inventory II, 12.2 ± 7.2 vs 6.2 ± 6.1; p < 0.0001) were worse in patients with 5-2-1 positive criteria as well. Conclusions QoL is worse in patients meeting ≥1 of the 5-2-1 criteria. This group of patients and their caregivers are more affected as a whole. These criteria could be useful for identifying patients in which it is necessary to optimize Parkinson's treatment.

Lipid-based nanodelivery approaches for dopamine-replacement therapies in Parkinson's disease: From preclinical to translational studies. Biomaterials 2019; 232:119704. [PMID: 31901690 DOI: 10.1016/j.biomaterials.2019.119704] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Revised: 12/09/2019] [Accepted: 12/18/2019] [Indexed: 12/26/2022]
Abstract
The incidence of Parkinson's disease (PD), the second most common neurodegenerative disorder, has increased exponentially as the global population continues to age. Although the etiological factors contributing to PD remain uncertain, its average incidence rate is reported to be 1% of the global population older than 60 years. PD is primarily characterized by the progressive loss of dopaminergic (DAergic) neurons and/or associated neuronal networks and the subsequent depletion of dopamine (DA) levels in the brain. Thus, DA or levodopa (l-dopa), a precursor of DA, represent cardinal targets for both idiopathic and symptomatic PD therapeutics. While several therapeutic strategies have been investigated over the past decade for their abilities to curb the progression of PD, an effective cure for PD is currently unavailable. Even DA replacement therapy, an effective PD therapeutic strategy that provides an exogenous supply of DA or l-dopa, has been hindered by severe challenges, such as a poor capacity to bypass the blood-brain barrier and inadequate bioavailability. Nevertheless, with recent advances in nanotechnology, several drug delivery systems have been developed to bypass the barriers associated with central nervous system therapeutics. In here, we sought to describe the adapted lipid-based nanodrug delivery systems used in the field of PD therapeutics and their recent advances, with a particular focus placed on DA replacement therapies. This work initially explores the background of PD; offers descriptions of the most recent molecular targets; currently available clinical medications/limitations; an overview of several lipid-based PD nanotherapeutics, functionalized nanoparticles, and technical aspects in brain delivery; and, finally, presents future perspectives to enhance the use of nanotherapeutics in PD treatment.

Abstract
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. Methods OBSERVE-PD, a cross-sectional, international, observational study, was conducted with 2615 PD patients at 128 movement disorder centers in 18 countries. Motor and non-motor symptoms, activities of daily living, and quality-of-life end points were assessed. The correlation between physician’s global assessment of advanced PD and the advanced PD criteria from a consensus of an international group of experts (Delphi criteria for APD) were evaluated. Results According to physician’s judgment, 51% of patients were considered to have APD. There was a moderate correlation between physician’s judgment and Delphi criteria for APD (K = 0.430; 95% CI 0.406–0.473). Activities of daily living, motor symptom severity, dyskinesia duration/disability, “Off” time duration, non-motor symptoms, and quality-of-life scores were worse among APD vs. non-APD patients (p < 0.0001 for all). APD patients (assessed by physicians) had higher disease burden by motor and non-motor symptoms compared with non-APD patients and a negative impact on activities of daily living and quality of life. Conclusions These findings aid in identifying standard APD classification parameters for use in practicing physicians. Improvements in identification of APD patients may be particularly relevant for optimizing treatment strategies including transitioning to device-aided treatment.

Abstract
AIMS To carry out a cost-utility analysis comparing the cost-effectiveness of levodopa carbidopa intestinal gel (LCIG) with standard of care (SOC) in patients with advanced Parkinson's Disease (aPD) unsuitable for apomorphine or deep brain stimulation (DBS). LCIG is the only treatment option in this small, but clinically important, population. METHODS A Markov model with 25 disease states based on disease stage and off-time status plus death. Patients enter the model with aPD spending >50% of their waking day in the off-state. Patients progress through the model in 6-monthly cycles for 20 years to approximate lifetime treatment and capture long-term costs and effects of therapy. Inputs are based on LCIG clinical trials for clinical outcomes and health state utilities, the literature for health state transitions and use UK-based input data wherever possible (drug costs, disease/adverse event management costs, discontinuation rates, mortality rates). LIMITATIONS Data collection can be challenging in this small, elderly population with advanced disease, therefore some model inputs were estimated, rather than collected directly. It was assumed that a reduction in off-time was the only benefit after the first year of treatment with LCIG; this is a conservative approach, since there may be additional clinical benefits. RESULTS There is a considerable incremental gain in quality adjusted life years (QALYs) for patients treated with LCIG of 1.26 QALY with an associated incremental cost-effectiveness ratio (ICER) of £52,110. If the impact on caregivers is included, the ICER reduces to £47,266. CONCLUSIONS In cases where there is an orphan population, with no alternative treatment options, HTA assessments have a broader decision-making framework and the ICER is interpreted in this context. In the setting of a very small population, with considerable unmet need, LCIG represents value for money, as reflected by funding approval across the UK.

Abstract
BACKGROUND Lack of a global consensus on the definition of advanced Parkinson's disease (APD) and considerations for timing of device-aided therapies may result in heterogeneity in care. OBJECTIVES To reach consensus among movement disorder specialists regarding key patient characteristics indicating transition to APD and guiding appropriate use of device-aided therapies in the management of PD symptoms. METHODS A Delphi-panel approach was utilized to synthesize opinions of movement disorder specialists and build consensus. RESULTS A panel was comprised of movement disorder specialists from 10 European countries with extensive experience of treating PD patients (mean =24.8 ± 7.2 years). Consensus on indicators of suspected APD and eligibility for device-aided therapies were based on motor symptoms, non-motor symptoms, and functional impairments. Key indicators of APD included: (i) motor-moderate troublesome motor fluctuations, ≥1 h of troublesome dyskinesia/day, ≥2 h "off" symptoms/day, and ≥5-times oral levodopa doses/day; (ii) non-motor-mild dementia, and non-transitory troublesome hallucinations; (iii) functional impairment-repeated falls despite optimal treatment, and difficulty with activities of daily living. Patients with good levodopa response, good cognition, and <70 years of age were deemed as good candidates for all three device-aided therapies. Patients with troublesome dyskinesia were considered good candidates for both levodopa-carbidopa intestinal gel and Deep Brain Stimulation (DBS). PD patients with levodopa-resistant tremor were considered good candidates for DBS. CONCLUSION Identifying patients progressing to APD and suitable for device-aided therapies will enable general neurologists to assess the need for referral to movement disorder specialists and improve the quality of care and patient outcomes.

Abstract
Background Deficits in executive functions (EFs) are frequently detected in patients with Parkinson’s disease (PD). The Frontal Assessment Battery (FAB) is a screening test for assessing EFs although it has not been so far adapted and validated in Spain. We evaluated the reliability and validity of the Spanish version of the FAB (FAB-E) in PD patients. Materials and methods Our study included 54 healthy subjects and 67 PD patients. Cognitive assessment of participants was conducted using the FAB-E, Mini-Mental State Examination (MMSE), Trail Making Test (TMT), Revised-Barcelona Test (RBT) and Executive Interview (EXIT-25). Internal consistency, intra- and test-retest reliabilities, concurrent and discriminant validity of the FAB-E were examined. To evaluate the influence of cognitive dysfunction in PD on the performance of the FAB-E, we also classified the PD patients into groups according to their cognitive status as measured by the MMSE using published criteria to identify cognitive deficits in PD. Results The FAB-E showed good internal consistency (α = 0.751). The intraclass correlation coefficients (ranging from 0.559 to 0.891) and Spearman correlations (from 0.494 to 0.864) of the FAB-E subtests indicated a good-strong reliability. The total and subtest scores generally showed a good concurrent validity, except for the prehension behaviour item of the FAB-E and the Interference and Go/no-go tasks of the EXIT-25 that presented low estimates. Excluding the prehension behaviour subtest, the performance of the FAB-E was higher in the control group than in PD patients. Cognitive dysfunction in PD patients also indicated significant poorer FAB-E scores excepting the motor and prehension behaviour subtests. Discriminant analysis determined a cut-off of 14.5 was optimal to differentiate healthy subjects from PD patients. Moreover, a cut-off <12.5 allocated satisfactorily those PD patients with cognitive impairment (MMSE<26) and scores <11.5 classified suitably those PD patients with dementia (MMSE<24). Conclusion The FAB-E is an accurate tool for evaluating EFs in patients with PD and can provide useful information for distinguishing PD patients with and without cognitive dysfunction at a bedside assessment.

Abstract
Parkinson’s disease (PD) is characterized by loss of dopamine (DA) neurons in the substantia nigra pars compacta (SNc) and a subsequent reduction in striatal DA levels. Recent studies have shown that systemic administration of subtoxic doses of epothilone B (EpoB), a microtubule stabilizing agent, enhances axonal regeneration. However, the underlying alterations in cellular mechanisms remain undetermined. In the present study, we investigated the neuroprotective effects of EpoB on DA neurons in mouse model of PD induced by 6-hydroxyDA (6-OHDA) and in vitro. The results indicated that EpoB improved behavioral deficits, protected the nigrostriatal dopaminergic projections and restored DA level in the striatum of mice exposed to 6-OHDA. Meanwhile, EpoB attenuated microglia activation in the SNc of PD mice. Furthermore, EpoB treatment ameliorated 6-OHDA induced cytotoxicity to MN9D dopaminergic cells in a co-culture transwell system of BV2/MN9D cells, and redistributed the cytoskeleton of microglial BV2 and caused the morphological transition, inhibited the polarization to the M1 phenotype by suppressing expression of pro-inflammatory factors including interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α. Overall, our study suggested that EpoB treatment protects nigral DA neurons and projections through limiting the cytotoxicity of activated microglia in 6-OHDA lesioned mice.

Abstract
Advanced Parkinson's disease (APD) is characterized by increased functional disability, caused by motor complications, the presence of axial symptoms, and emergent disease- and drug-related non-motor symptoms. One of the advanced therapies available is intrajejunal infusion of levodopa/carbidopa intestinal gel (LCIG); however, patient selection for this treatment is sometimes difficult, particularly because of overlapping indications with other alternatives. In recent years, strong evidence has supported the use of LCIG in treating motor fluctuations associated with APD, and several clinical studies provide emerging evidence for additional benefits of LCIG treatment in certain patients. This article provides an overview of the published literature on the benefits, limitations, and drawbacks of LCIG in relation to PD symptoms, the psychosocial impact of the disease, and the quality of life of patients, with the aim of determining candidates for whom treatment with LCIG would be beneficial. According to current evidence, patients with APD (defined as inability to achieve optimal control of the disease with conventional oral treatment), a relatively well-preserved cognitive-behavioral status, and good family/caregiver would count as suitable candidates for LCIG treatment. Contraindications in the opinion of the authors are severe dementia and active psychosis.

Abstract
To date, no consensus exists on the key factors for diagnosing advanced Parkinson disease (APD). To obtain consensus on the definition of APD, we performed a prospective, multicenter, Spanish nationwide, 3-round Delphi study (CEPA study). An ad hoc questionnaire was designed with 33 questions concerning the relevance of several clinical features for APD diagnosis. In the first-round, 240 neurologists of the Spanish Movement Disorders Group participated in the study. The results obtained were incorporated into the questionnaire and both, results and questionnaire, were sent out to and fulfilled by 26 experts in Movement Disorders. Review of results from the second-round led to a classification of symptoms as indicative of “definitive,” “probable,” and “possible” APD. This classification was confirmed by 149 previous participating neurologists in a third-round, where 92% completely or very much agreed with the classification. Definitive symptoms of APD included disability requiring help for the activities of daily living, presence of motor fluctuations with limitations to perform basic activities of daily living without help, severe dysphagia, recurrent falls, and dementia. These results will help neurologists to identify some key factors in APD diagnosis, thus allowing users to categorize the patients for a homogeneous recognition of this condition.

Abstract
Background Treatment of advanced-stage idiopathic Parkinson's disease (PD) is a demanding challenge, and in Germany, medication regimen adjustments are often made during inpatient stays. Admissions often follow an acute worsening of symptoms and functioning. In order to reduce long and expensive inpatient stays, and to provide more frequent consultations, a 24/7 live stream telemedicine home treatment service was established. Methods A pilot study was conducted in which laptops were distributed to 50 patients for 1 year to see whether such a service was feasible (in terms of patient participation and compliance) and whether this intervention affected the patient's condition, measured in UPDRS, Mini-Mental Status Examination (MMSE), 39-item Parkinson's Disease Questionnaire (PDQ39), and H & Y Scale. Results Seventy-two percent (36) of the patients were compliant and did not experience technical issues. Patients lived, on average, 198 ± 183 km away from the specialist clinic. In total, 264 video conversations took place with 6.9 ± 7.2 (0-29) calls per patient. We found a significant improvement in PDQ39 scores, but not in UPDRS, MMSE, or H & Y scores, at 1 year. Conclusions Our data shows that 24/7 live stream telemedicine is feasible and can help to improve quality of life. However, a detailed preliminary review of the patient's willingness to use such a service should be made to obtain the best results. Improvement of the technical setup and network coverage would facilitate an improved service and increase efficiency.

Objetivo Explorar los principales aspectos psicosociales que influyen en el afrontamiento de la enfermedad de los pacientes con enfermedad de Parkinson (EP) y sus familiares cuidadores. Diseño Estudio cualitativo exploratorio que constituye la segunda fase de un proyecto de metodología combinada. Emplazamiento Estudio multicéntrico realizado en la Comunidad Autónoma de Navarra en 2014 con la colaboración de Atención Primaria del Servicio Navarro de Salud-Osasunbidea, la Clínica Universidad de Navarra y la Asociación Navarra de Parkinson. Participantes Un total de 21 participantes: 9 personas con EP, 7 familiares cuidadores y 5 profesionales sociosanitarios. Método Los participantes fueron seleccionados mediante muestreo opinático. Se realizaron grupos focales hasta que se consideró adecuada la saturación de los datos. Las transcripciones fueron analizadas por 2 investigadores a través de un análisis de contenido. Resultados Se identificaron 3 aspectos que influían en cómo pacientes y familiares afrontaban la EP: funcionalidad de la atención sanitaria; entorno familiar, y aceptación de la enfermedad. Considerando estos resultados, se proponen estrategias que podrían promover estos aspectos desde atención primaria, para así mejorar la adaptación a esta enfermedad en pacientes y en sus familiares cuidadores. Conclusiones La atención sociosanitaria de las personas con EP debería adoptar un enfoque integral que aborde el control de los síntomas del paciente y que responda también a los aspectos psicosociales que influyen en el afrontamiento de la enfermedad, tanto en los pacientes como en sus familiares cuidadores.
