Real-world use of Safinamide in motor fluctuating Parkinson's disease patients in Italy.

INTRODUCTION: Safinamide is a recent antiparkinsonian drug that modulates both dopaminergic and glutamatergic systems with positive effects on motor and nonmotor symptoms of Parkinson's disease (PD). Here, we aimed to describe the efficacy and safety of safinamide in the Italian PD patients in real-life conditions. METHODS: We performed a sub-analysis of the Italian cohort of the SYNAPSES study, a multi-country, multi-center, retrospective-prospective cohort observational study, designed to investigate the use of safinamide in routine clinical practice. Patients received for the first time a treatment with safinamide and were followed up for 12 months. The analysis was conducted on the overall population and in subgroups of interest: i) patients > 75 years, ii) patients with relevant comorbidities and iii) patients affected by psychiatric symptoms. RESULTS: Italy enrolled 616/1610 patients in 52 centers, accounting for 38% of the entire SYNAPSES cohort. Of the patients enrolled, 86.0% were evaluable at 12 months, with 23.3% being > 75 years, 42.4% with psychiatric conditions and 67.7% with relevant comorbidities. Safinamide was effective on motor symptoms and fluctuations as measured through the Unified PD rating scale III and IV scores, and on the total score, without safety issues in none of the subgroups considered. CONCLUSION: The SYNAPSES data related to Italian patients confirms the good safety profile of safinamide even in special groups of patients. Motor fluctuations and motor impairment improved at the follow-up suggesting the significant role of safinamide in managing motor symptoms in PD patients.

Transcranial magnetic resonance-guided focused ultrasound thalamotomy as a safe treatment option in multiple sclerosis patients with essential tremor.

Transcranial magnetic resonance-guided focused ultrasound is a recently introduced incisionless treating option for essential tremor and tremor-dominant idiopathic Parkinson disease. There is preliminary evidence that it may result in a promising effective treatment option for other movement disorders too. Here, we report on two patients with multiple sclerosis with medication refractory debilitating essential tremor comorbidity who successfully underwent unilateral Vim tcMRgFUS thalamotomy for tremor control. Patients' clinical condition and expanded disability status scale scores showed no changes during the 1-year follow-up period with no evidence of multiple sclerosis activity or progression.

Analysis of the LRP10 gene in patients with Parkinson's disease and dementia with Lewy bodies from Southern Italy.

Recently, the LRP10 gene has been associated with Parkinson's disease (PD), Parkinson's disease with dementia (PDD), and dementia with Lewy bodies (DLB). The aim of the present study was to evaluate the presence of mutations of the LRP10 gene in patients with PD or DLB from Southern Italy. Sequencing analysis revealed only 2 missense and 3 synonymous variants in patients and control subjects and a rare variant p.L622F in a PD case. These results suggest that LRP10 mutations are not a frequent cause of PD and DLB in Southern Italy.

Stroke incidence and case fatality: a 9-year prospective population-based study in an elderly population of Bagheria, Italy.

BACKGROUND: The incidence of stroke in high-income countries has been on the decline; however, few epidemiological surveys have been conducted in recent years to specifically estimate the incidence along with outcome of stroke, in Italy. This study aimed to examine the incidence and case fatality rates of stroke in an elderly Italian population. METHODS: A cohort of 2200 people > 65 years was randomly stratified from the total elderly population of Bagheria, Italy. A 9-year prospective population-based study was performed (19,800 person/years). RESULTS: We identified 112 first-ever strokes, 53 females and 59 males: 82 (73.1%) ischemic, 13(11.6%) intracerebral haemorrhages, 6 (5.35%) subarachnoid haemorrhages, while 11(9.8%) were classified as undetermined strokes. The crude overall annual incidence was 5.65 per 1000 (95%CI: 4.61 to 6.70) for first-ever stroke. The overall crude incidence rates were 4.74 per 1000 (5.08 for males and 4.46 for females) for ischemic stroke, 0.65 (0.99 for males and 0.37 for females) for intracerebral haemorrhage, and 0.03 for subarachnoid haemorrhage. The incidence rate for first-ever stroke was 5.4 per 1000 (95% CI: 5.36 to 5.45) after adjustment for the 2015 World population and 5.56 (95% CI: 5.52 to 5.61), compared to the 2015 European population. Overall case fatality rates for first-ever stroke was 8.19% at 28 days and 24.1% at 1 year. CONCLUSION: Our study shows that in the elderly population investigated, stroke incidence and case fatality rates resulted being lower, compared to those from Italian and most European populations. Similar to previous studies, these rates increased linearly with age and were higher in males.

Intraoperative imaging findings in transcranial MR imaging-guided focused ultrasound treatment at 1.5T may accurately detect typical lesional findings correlated with sonication parameters.

OBJECTIVES: To assess the intraoperative neuroimaging findings in patients treated with transcranial MR-guided focused ultrasound (tcMRgFUS) thalamotomy using 1.5T equipment in comparison with the 48-h follow-up. METHODS: Fifty prospectively enrolled patients undergoing unilateral tcMRgFUS thalamotomy for either medication-refractory essential tremor (n = 39) or Parkinson tremor (n = 11) were included. Two radiologists evaluated the presence and size of concentric lesional zones (zone I, zone II, and zone III) on 2D T2-weighted sequences acquired intraoperatively after the last high-energy sonication and at 48 h. Sonication parameters including number of sonications, delivered energy, and treatment temperatures were also recorded. Differences in lesion pattern and size were assessed using the McNemar test and paired t test, respectively. RESULTS: Zones I, II, and III were visualized in 34 (68%), 50 (100%), and 44 (88%) patients, and 31 (62%), 50 (100%), and 45 (90%) patients after the last high-energy sonication for R1 and R2, respectively. All three concentric zones were visualized intraoperatively in 56-58% of cases. Zone I was significantly more commonly visualized at 48 h (p < 0.001). Diameter of zones I and II and the thickness of zone III significantly increased at 48 h (p < 0.001). Diameters of zones I and II measured intraoperatively demonstrated significant correlation with thermal map temperatures (p ≤ 0.001). Maximum temperature significantly correlated with zone III thickness at 48 h. A threshold of 60.5° had a sensitivity of 56.5-66.7% and a specificity of 70.5-75.5% for thickness > 6 mm at 48 h. CONCLUSIONS: Intraoperative imaging may accurately detect typical lesional findings, before completing the treatment. These imaging characteristics significantly correlate with sonication parameters and 48-h follow-up. KEY POINTS: • Intraoperative T2-weighted images allow the visualization of the zone I (coagulation necrosis) in most of the treated patients, while zone II (cytotoxic edema) is always detected. • Lesion size depicted with intraoperative transcranial MRgFUS imaging correlates well with procedure parameters. • Intraoperative transcranial MRgFUS imaging may have a significant added value for treating physicians.

Effects of transcranial random noise stimulation combined with Graded Repetitive Arm Supplementary Program (GRASP) on motor rehabilitation of the upper limb in sub-acute ischemic stroke patients: a randomized pilot study.

We evaluated the combined use of transcranial random noise stimulation (tRNS) with the Graded Repetitive Arm Supplementary Program (GRASP) in sub-acute ischemic stroke patients suffering from arm impairment. Eighteen ischemic stroke patients with upper limb disability were randomly assigned to either the GRASP + tRNS or GRASP + Sham stimulation group. Fugl-Meyer Assessment-Upper extremity (FMA-UE) was performed to evaluate upper limb impairment before treatment (T0), after the last stimulation (T1) and after 30 days (T2). At T1 and T2, beneficial effects in the tRNS group correlated with better FMA-UE score than sham stimulation group (p < 0.001) and these results did not correlate to stroke severity, because no associations were observed between National Institute of Health Stroke Scale and FMA UE T1 and T2. This study displayed a good feasibility and was the first to evaluate the use of tRNS in association with Grasp in sub-acute stroke survivors having arm impairment to improve arm motor recovery.

Urological dysfunctions in patients with Parkinson's disease: clues from clinical and non-invasive urological assessment.

BACKGROUND: Autonomic nervous system dysfunction, common in patients with Parkinson's disease (PD), causes significant morbidity and it is correlated with poor quality of life. To assess frequency of urinary symptoms in patients with PD, without conditions known to interfere with urinary function. METHODS: Non-demented PD patients were consecutively enrolled from the outpatients clinic of our department. Scales investigating motor and non-motor symptoms were carried out. Evaluation of urinary dysfunctions was carried out using the AUTonomic Scale for Outcomes in Parkinson's disease (SCOPA-AUT) questionnaire. Patients underwent noninvasive urological studies (nUS), including uroflowmetry and ultrasound of the urinary tract. RESULTS: Forty-eight (20 women, 42%) out of 187 PD patients met the inclusion criteria and were enrolled in the study. Mean SCOPA-AUT score was 14.1 ± 6.9 (urinary symptoms subscore 5.2 ± 3.8). Among those evaluated by the SCOPA-AUT scale, the urinary symptoms were among the most common complaints (93.8%). At nUS mean maximum flow rate (Qmax) was 17.9 ± 9.1 ml/s, and mean postvoid residual (PVR) urine volume was 24.4 ± 44.1 ml. Ultrasound investigation documented prostate hypertrophy in 12 male patients (42.8%). Urinary items of the SCOPA-AUT (SCOPA-U subscore) correlated with measures of disease severity only in female patients. CONCLUSION: Urinary symptoms and abnormal findings in nUS are common in PD. Though nigrostriatal degeneration might be responsible for urinary symptoms also in the early-intermediate stage of the disease, when urinary dysfunction occurs other medical conditions need to be excluded.

Preliminary experience with a transcranial magnetic resonance-guided focused ultrasound surgery system integrated with a 1.5-T MRI unit in a series of patients with essential tremor and Parkinson's disease.

OBJECTIVE Transcranial magnetic resonance-guided focused ultrasound surgery (tcMRgFUS) is one of the emerging noninvasive technologies for the treatment of neurological disorders such as essential tremor (ET), idiopathic asymmetrical tremor-dominant Parkinson's disease (PD), and neuropathic pain. In this clinical series the authors present the preliminary results achieved with the world's first tcMRgFUS system integrated with a 1.5-T MRI unit. METHODS The authors describe the results of tcMRgFUS in a sample of patients with ET and with PD who underwent the procedure during the period from January 2015 to September 2017. A monolateral ventralis intermedius nucleus (VIM) thalamic ablation was performed in both ET and PD patients. In all the tcMRgFUS treatments, a 1.5-T MRI scanner was used for both planning and monitoring the procedure. RESULTS During the study period, a total of 26 patients underwent tcMRgFUS thalamic ablation for different movement disorders. Among these patients, 18 were diagnosed with ET and 4 were affected by PD. All patients with PD were treated using tcMRgFUS thalamic ablation and all completed the procedure. Among the 18 patients with ET, 13 successfully underwent tcMRgFUS, 4 aborted the procedure during ultrasound delivery, and 1 did not undergo the tcMRgFUS procedure after stereotactic frame placement. Two patients with ET were not included in the results because of the short follow-up duration at the time of this study. A monolateral VIM thalamic ablation in both ET and PD patients was performed. All the enrolled patients were evaluated before the treatment and 2 days after, with a clinical control of the treatment effectiveness using the graphic items of the Fahn-Tolosa-Marin tremor rating scale. A global reevaluation was performed 3 months (17/22 patients) and 6 months (11/22 patients) after the treatment; the reevaluation consisted of clinical questionnaires, neurological tests, and video recordings of the tests. All the ET and PD treated patients who completed the procedure showed an immediate amelioration of tremor severity, with no intra- or posttreatment severe permanent side effects. CONCLUSIONS Although this study reports on a small number of patients with a short follow-up duration, the tcMRgFUS procedure using a 1.5-T MRI unit resulted in a safe and effective treatment option for motor symptoms in patients with ET and PD. To the best of the authors' knowledge, this is the first clinical series in which thalamotomy was performed using tcMRgFUS integrated with a 1.5-T magnet.

Association between multiple sclerosis, cancer risk, and immunosuppressant treatment: a cohort study.

BACKGROUND: The association between multiple sclerosis (MS) and cancer has long been investigated with conflicting results. Several reports suggest an increased cancer risk among MS patients treated with immunosuppressant (IS) drugs. METHODS: We performed a cohort study including MS patients recruited at the Neurological Department of the University of Palermo. Mean follow-up period was ten years for the whole cohort. We calculated cancer incidence among patients treated with IS. Incidence rates were compared in the cohort by calculating the relative risk according to length and dose of exposure to IS. Cancer incidence among MS patients was compared to cancer incidence in the general population of Sicily in similar age groups. RESULTS: On an overall cohort of 531 MS patients (346 women and 185 men) exposed to IS, we estimated a crude incidence rate for cancer of 2.26% (2.02% in women, 2.7% in men). Cancer risk was higher compared to rates observed among an equal number of patients not exposed to IS, and to the risk in the general population in Sicily at similar age groups (adjusted HR: 11.05; CI 1.67-73.3; p = 0.013). CONCLUSION: The present study showed a higher cancer risk in MS patients associated only to previous IS exposure. Studies on long-term outcomes are essential to evaluate the possibility that treatment options that need to be considered for a long time-period may modify risk for life threatening diseases.

Juvenile migraine and allodynia: results of a retrospective study.

BACKGROUND: There are only 2 small sample studies investigating allodynia in the pediatric population. The aim of this study was to evaluate the frequency of allodynia during cephalalgic attacks in a juvenile population with primary headaches and its association with other symptoms of migraine. METHODS: We reviewed all medical records of patients with primary headache consecutively seen during a 2-year period. Frequency of allodynia was evaluated, by means of a questionnaire, consisting of 6 questions (for example: Do you avoid touching your head when you have a migraine attack?). RESULTS: Two hundred thirty children suffering from primary headache were seen during the study period. Two hundred two children were affected by migraine, 28 (12.2%) by other primary headaches. Migraineurs significantly more frequently complained of allodynia compared to other primary headaches (37% vs 0%). At multivariate analysis, allodynia was significantly associated with pain aggravated by physical activity (adjusted odds ratio [ORa ] 2.0, 95% confidence interval [CI] 1.0, 3.8), phonophobia (ORa 2.3, 95% CI 1.0, 5.1), and nausea (ORa 1.9, 95% CI 1.0, 3.7). CONCLUSION: According to our data, allodynia is common during pediatric migraine attacks. The association between allodynia and physical activity, nausea and phonophobia are supported by studies on adult population and suggests specific physiopathological mechanisms.

Migraine in a pediatric population: a clinical study in children younger than 7 years of age.

AIM: Migraines in children younger than 7 years of age have received limited attention in the published literature. The aim of this study is to describe the characteristics of migraine phenotypes in children younger than 7 years, and to compare them with migraines in children older than 7 years of age. METHOD: We reviewed all standard clinical files, collected over 4 years, related to children with a diagnosis of primary headache. We included all children younger than 7 years diagnosed with migraine in our study. RESULTS: A total of 374 children (188 males, 186 females) were affected by migraine with/without aura: 40 of these patients (10.7%; 20 males, 20 females; mean age 5y 7mo, SD 1y 2mo) where younger than 7 years old. The frequencies of the main migraine features in the younger age group were similar to those of children older than 7 years, with the exception of a shorter duration of migraine and reduced frequency of attacks. INTERPRETATION: In children younger than 7 years of age, the clinical phenotype of migraine is similar to that seen in older children. We propose that there is a general genetic migraine susceptibility that, in the presence of activating environmental factors, may induce typical attacks of migraine in individuals already predisposed to migraine attacks. Therefore, different modules induce different clinical features within the different age groups, but there is no difference in the frequencies of clinical phenotypes between the two age groups.

In patient's with Parkinson disease, autonomic symptoms are frequent and associated with other non-motor symptoms.

BACKGROUND: Autonomic symptoms and sleep disorders are common non-motor symptoms of Parkinson disease (PD), which are correlated with poor quality of life for patients. PURPOSE: To assess the frequency of autonomic symptoms in a consecutive series of PD patients and to correlate them with other motor and non-motor symptoms. METHODS: All consecutive non-demented PD patients who underwent an extensive evaluation including Hoehn and Yahr staging, Unified Parkinson's Disease Rating Scale, Beck's Depression Inventory, Neuropsychiatric Inventory, PDQ-39 Scale, the Parkinson's diseases Sleep Scale, the Epworth Sleepiness Scale and SCOPA-AUT scale were enrolled. Comorbidity has been also considered. Supine to standing position blood pressure and cardiac frequency changes were also measured. RESULTS: 135 PD patients were included (mean age at interview 67.7; mean disease duration: 5.3 years). Patients were stratified according to mean SCOPA-AUT scale score (13.1). Those with higher SCOPA-AUT scale score were significantly older, had longer disease duration, worse disease stage, worse quality of sleep, were more severely affected, and were also taking a higher dosage of levodopa. At multivariate analysis, older age, longer disease duration, and worse quality of sleep were independently associated with higher SCOPA-AUT scale scores. CONCLUSIONS: Our results remark the role of autonomic symptoms in PD. In our patient population, characterized by mild to moderate disease severity, most of the patients complained of autonomic nervous system involvement (84%). A significant association between autonomic symptoms and sleep disorders was also observed.

Transcranial direct current stimulation for treatment of freezing of gait: a cross-over study.

BACKGROUND AND OBJECTIVE: Progression of Parkinson's disease (PD) is frequently characterized by the occurrence of freezing of gait (FOG) representing a disabling motor complication. We aim to investigate safety and efficacy of transcranial direct current stimulation of the primary motor cortex of PD patients with FOG. METHODS: In this cross-over, double-blind, sham-controlled study, 10 PD patients with FOG persisting in "on" state underwent anodal and sham direct current stimulation for 5 consecutive days. Clinical assessment over a 1-month period was performed. RESULTS: A significant improvement of gait, as assessed by the Stand Walk Sit test, with reduction in number and duration of FOG episodes, along with a significant reduction in the Unified Parkinson's Disease Rating Scale score, were observed after anodal stimulation. Beneficial effects were more evident after the entire 5-day stimulation session, and persisted until the end of the observation period. CONCLUSIONS: Anodal transcranial direct current stimulation of the motor cortex is safe and has therapeutic potential in PD patients with FOG.

Neurofunctional correlates of attention rehabilitation in Parkinson's disease: an explorative study.

The effectiveness of cognitive rehabilitation (CR) in Parkinson's disease (PD) is in its relative infancy, and nowadays there is insufficient information to support evidence-based clinical protocols. This study is aimed at testing a validated therapeutic strategy characterized by intensive computer-based attention-training program tailored to attention deficits. We further investigated the presence of synaptic plasticity by means of functional magnetic resonance imaging (fMRI). Using a randomized controlled study, we enrolled eight PD patients who underwent a CR program (Experimental group) and seven clinically/demographically-matched PD patients who underwent a placebo intervention (Control group). Brain activity was assessed using an 8-min resting state (RS) fMRI acquisition. Independent component analysis and statistical parametric mapping were used to assess the effect of CR on brain function. Significant effects were detected both at a phenotypic and at an intermediate phenotypic level. After CR, the Experimental group, in comparison with the Control group, showed a specific enhanced performance in cognitive performance as assessed by the SDMT and digit span forward. RS fMRI analysis for all networks revealed two significant groups (Experimental vs Control) × time (T0 vs T1) interaction effects on the analysis of the attention (superior parietal cortex) and central executive neural networks (dorsolateral prefrontal cortex). We demonstrated that intensive CR tailored for the impaired abilities impacts neural plasticity and improves some aspects of cognitive deficits of PD patients. The reported neurophysiological and behavioural effects corroborate the benefits of our therapeutic approach, which might have a reliable application in clinical management of cognitive deficits.

Early and late mortality of spontaneous hemorrhagic transformation of ischemic stroke.

BACKGROUND: Hemorrhagic transformation (HT), a complication of ischemic stroke (IS), might influence patient's prognosis. Our aim is to evaluate, in a hospital-based series of patients not treated with thrombolysis, the relationship between HT and mortality. METHODS: We compared mortality of individuals with spontaneous HT with that of individuals without. Medical records of patients diagnosed with anterior IS were retrospectively reviewed. Outcome measures were 30- and 90-day survival after IS onset. Kaplan-Meier estimates were used to construct survival curves. Cox proportional hazards model was used to estimate hazard ratio (HR) for the main outcome measure (death). HT was stratified in hemorrhagic infarction and parenchymal hematoma (PH). We also evaluated the relationship between HT and the main mortality risk factors (gender, age, premorbid status, severity of stroke, and radiological features). RESULTS: Thirty days from stroke onset, 8.1% (19 of 233) of patients died. At multivariate analysis, PH (HR: 7.7, 95% confidence interval [CI]: 2.1, 27.8) and low level of consciousness at admission (HR: 5.0, 95% CI: 1.3, 18.6) were significantly associated with death. At 3-month follow-up, mortality rate was 12.1% (28 of 232). At multivariate analysis, large infarct size (HR: 2.7, 95% CI: 1.2, 6.0) and HT (HR: 2.3, 95% CI: 1.0, 5.4) were independent risk factors for mortality. Parenchymal hematoma was, however, the strongest predictor of late mortality (HR: 7.9, 95% CI: 2.9, 21.4). CONCLUSIONS: Neurological status and infarct size play a significant role, respectively, in early and late mortality after IS. Parenchymal hematoma independently predicts both early and late mortality.

Efficacy and Safety of Rescue Treatment with Plasma Exchange in Patients with Acute Inflammatory Neurological Disorders: A Single Center Experience.

BACKGROUND: Therapeutic plasma exchange (TPE) is a highly effective rescue treatment for patients with acute exacerbation of neuroimmunological disease that removes circulating autoantibodies and inflammatory components from the bloodstream. The aims of this study are to explore the safety and the effectiveness of TPE in patients with autoimmune neurological disorders. METHODS: We retrospectively evaluated the frequency of adverse events (AEs) and the effectiveness of TPE using the modified Ranking Scale (mRS) in patients with acute neurological flares who underwent TPE at the University Hospital of Palermo. RESULTS: Of 59 patients, the majority underwent TPE due to multiple sclerosis (MS) relapse. In 23.7% of cases, TPE was performed before obtaining a definite diagnosis due to the severity of the clinical presentation. After TPE, the mRS score was globally reduced (p < 0.0001), and this effect was marked in patients with MS, Guillain-Barré syndrome, and myasthenia gravis crisis but not in those with paraneoplastic syndromes. Circulating pathogenetic antibodies, younger age, and the early use of TPE were factors strongly associated with TPE effectiveness. The overall safety profile of TPE was satisfactory with an AE frequency of 15%. CONCLUSIONS: These results highlight the early use of TPE in patients with circulating pathogenetic antibodies as well as its favorable safety profile.

Health and economic impact of dapagliflozin for type 2 diabetes patients who had or were at risk for atherosclerotic cardiovascular disease in the Italian general practitioners setting: a budget impact analysis.

AIM: In 2022, in Italy, general practitioners (GPs) have been allowed to prescribe SGLT2i in Type 2 Diabetes (T2D) under National Health Service (NHS) reimbursement. In the pivotal clinical trial named DECLARE-TIMI 58, dapagliflozin reduced the risk of hospitalization for heart failure, CV death and kidney disease progression compared to placebo in a population of T2D patients. This study evaluated the health and economic impact of dapagliflozin for T2D patients who had or were at risk for atherosclerotic cardiovascular disease in the Italian GPs setting. METHODS: A budget impact model was developed to assess the health and economic impact of introducing dapagliflozin in GPs setting. The analysis was conducted by adopting the Italian NHS perspective and a 3-year time horizon. The model estimated and compared the health outcomes and direct medical costs associated with a scenario with dapagliflozin and other antidiabetic therapies available for GPs prescription (scenario B) and a scenario where only other antidiabetic therapies are available (scenario A). Rates of occurrence of cardiovascular and renal complications as well as adverse events were captured from DECLARE-TIMI 58 trial and the literature, while cost data were retrieved from the Italian tariff and the literature. One-way sensitivity analyses were conducted to test the impact of model parameters on the budget impact. RESULTS: The model estimated around 442.000 patients eligible for the treatment with dapagliflozin in the GPs setting for each simulated year. The scenario B compared to scenario A was associated with a reduction in the occurrence of cardiovascular and renal complication (-1.83%) over the 3 years simulated. Furthermore, the scenario A allowed for an overall cost saving of 102,692,305€: 14,521,464€ in the first year, 33,007,064€ in the second and 55,163,777€ in the third. The cost of cost of drug acquisition, the probability of cardiovascular events and the percentage of patients potentially eligible to the treatment were the factor with largest impact on the results. CONCLUSIONS: The use of dapagliflozin in GPs setting reduce the number of CVD events, kidney disease progression and healthcare costs in Italy. These data should be considered to optimize the value produced for the T2D patients who had or were at risk for atherosclerotic cardiovascular disease.

ANXA1 mutation analysis in Italian patients with early onset PD.

Recently, a novel pathogenic variant in Annexin A1 protein (c.4G > A, p.Ala2Thr) has been identified in an Iranian consanguineous family with autosomal recessive parkinsonism. The deficiencies of ANXA1 could lead to extracellular SNCA accumulation, defects in intracellular signaling pathways and synaptic plasticity causing parkinsonism. The aim of this study was to identify rare ANXA1 variants in 95 early-onset PD patients from South Italy. Sequencing analysis of ANXA1 gene revealed only 2 synonymous variants in PD patients (rs1050305, rs149033255). Therefore, we conclude that the recently published ANXA1 mutation is not a common cause of EOPD in Southern Italy.

Exergaming in the treatment of gait, balance, and quality of life in Parkinson's disease: Overview of systematic reviews.

INTRODUCTION: Postural instability and gait impairments are common in people with PD, both of which have a negative effect on their quality of life. Systematic reviews have demonstrated benefits of using exergaming in enhancing these outcomes. However, there is no consensus over whether exergaming therapy is better than conventional physical therapy for enhancing gait, balance, and quality of life. OBJECTIVES: The aim of this overview is to systematically synthesize and evaluate the available evidence found in published systematic reviews and meta-analyses, on the effects of exergaming therapy on balance, gait, and quality of life, compared to conventional physical therapy or no intervention. METHODS: This overview was reported in accordance with the statement of Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). A comprehensive search was carried out in nine databases. Two reviewers independently extracted data using a standardized forms and the search strategy included terms related to intervention, population, and study type. The methodological quality of the included systematic reviews/meta-analysis (SRs/Mas) was evaluated using the "A Measurement Tool to Assess Systematic Reviews 2" (AMSTAR-2). The "Grading of Recommendations Assessment, Development and Evaluation" (GRADE) was used to assess the quality of the evidence. The risk of bias assessment was performed using the "Risk Of Bias In Systematic Reviews" (ROBIS). PROSPERO registration number: CRD42021238131. RESULTS: 112 SRs/MAs were found and nine of them were selected. Six reviews were rated as very low methodological quality and three reviews as low methodological quality. Five reviews were classified with low risk of bias and four reviews with high risk of bias. Most of the SR/MAs demonstrated significant effects on balance favoring exergaming therapy over conventional therapy, however those studies had been rated as very low quality of evidence. Inconclusive results were found for the quality of life and gait outcomes. CONCLUSION: Exergaming therapy shows promise for the rehabilitation of PD. However, this overview was unable to conclude with certainty that exergaming therapy is superior to conventional physical therapy in improving gait, balance, or quality of life in people with PD. The effectiveness of exergaming therapy in the treatment of people with PD still need to be verified by high-quality studies.
