Freezing of gait in Parkinson’s disease patients treated with bilateral subthalamic nucleus deep brain stimulation: A long-term overview

Bilateral subthalamic nucleus deep brain stimulation (STN-DBS) is an effective treatment in advanced Parkinson’s Disease (PD). However, the effects of STN-DBS on freezing of gait (FOG) are still debated, particularly in the long-term follow-up (>/=5-years). The main aim of the current study is to evaluate the long-term effects of STN-DBS on FOG. Twenty STN-DBS treated PD patients were included. Each patient was assessed before surgery through a detailed neurological evaluation, including FOG score, and reevaluated in the long-term (median follow-up: 5-years) in different stimulation and drug conditions. In the long term follow-up, FOG score significantly worsened in the off-stimulation/off-medication condition compared with the preoperative off-medication assessment (z = -1.930; p = 0.05) but not in the on-stimulation/off-medication (z = -0.357; p = 0.721). There was also a significant improvement of FOG at long-term assessment by comparing on-stimulation/off-medication and off-stimulation/off-medication conditions (z = -2.944; p = 0.003). These results highlight the possible beneficial long-term effects of STN-DBS on FOG

Freezing of Gait in Parkinson's Disease Patients Treated with Bilateral Subthalamic Nucleus Deep Brain Stimulation: A Long-Term Overview

Bilateral subthalamic nucleus deep brain stimulation (STN-DBS) is an effective treatment in advanced Parkinson's Disease (PD). However, the effects of STN-DBS on freezing of gait (FOG) are still debated, particularly in the long-term follow-up (≥5-years). The main aim of the current study is to evaluate the long-term effects of STN-DBS on FOG. Twenty STN-DBS treated PD patients were included. Each patient was assessed before surgery through a detailed neurological evaluation, including FOG score, and revaluated in the long-term (median follow-up: 5-years) in different stimulation and drug conditions. In the long term follow-up, FOG score significantly worsened in the off-stimulation/off-medication condition compared with the pre-operative off-medication assessment (z = -1.930; p = 0.05) but not in the on-stimulation/off-medication (z = -0.357; p = 0.721). There was also a significant improvement of FOG at long-term assessment by comparing on-stimulation/off-medication and off-stimulation/off-medication conditions (z = -2.944; p = 0.003). These results highlight the possible beneficial long-term effects of STN-DBS on FOG

SUSTAINABLE SOCIAL HOUSING

In Italy and abroad one of the main drivers of innovation in the building sector is actually the energy sustainability; its application in residential projects is more and more crucial to the quality of the project and its effectiveness in terms of performance. This paper focuses on all the aspects of the social and environmental sustainability of the project, and it describes the sustainable technologies utilized to build it. In particular, the paper focuses on the social housing intervention called "Cenni di Cambiamento" in Milan (Italy), which is placed in the research frame of the achievement of sustainability, declined in its broadest sense by the growth strategy of Europe 2020. ???Cenni di Cambiamento??? is known in Europe as the most advanced social housing project from the technological point of view, because it utilizes an experimental building system made by bearing wooden panel, cross-layered, whose potential allows to build multilevel buildings with high eco-green performance. Completed in 14 months, the towers in Via Cenni, with their 9 floors above ground, offer innovative housing solutions based on the culture of sustainable and cooperative housing. The choice to use an innovative construction technology was dictated by the necessity to build the towers in a short time, without compromising the quality of the building, but even raising the building performance designed to contain and control the consumption of energy and resources

The social manager as the guarantor of sustainability in Social Housing interventions

The boost in social housing interventions is the answer to the growing demand for new housing caused by higher social vulnerability in the wake of the economic and financial crisis in Europe. It meets the goal of inclusive growth, as defined in Europe 2020’s growth strategy. This paper deals with this issue starting from an analysis of the social events that are worsening the housing problem in Europe, and which are exasperated by the anti-crisis measures implemented by the Governments of the most financially stricken countries. This paper then highlights the key role played by social managers as the element that guarantees intervention sustainability. The case-study of the Fondazione Housing Sociale demonstrates how the social manager is a key element in social housing interventions

Association between radiological findings and severity of community-acquired pneumonia in children

Background: There are few published data concerning radiological findings and their relationship with community-acquired pneumonia (CAP) severity. The aim if this study was to assess radiographic findings in children with CAP of different severity in order to evaluate whether some parameters are associated with severe CAP. Methods. We analysed the characteristics of parenchymal densities in 335 chest radiographs of otherwise healthy children (173 males; mean age \ub1 standard deviation, 7.5 \ub1 4.5 years) admitted to our Emergency Room for CAP. Upon admission, chest radiographs were obtained in the two standard projections, and the children with severe or mild/moderate CAP were compared in order to identify any correlations between CAP severity and the radiological findings. Results: Seventy-six of the 335 enrolled children (22.7%) fulfilled the criteria for severe CAP. In comparison with the children with mild/moderate CAP, in severe CAP there was a significantly greater frequency of a bilateral multifocal distribution (p = 0.01), the simultaneous involvement of 653 sites (p = 0.007), and the involvement of the right hilum (p = 0.02). The same results were confirmed in the multiple logistic regression model. Conclusions: This study shows that radiological findings such as a multifocal bilateral distribution, the simultaneous involvement of at least three sites, and right hilar consolidation are associated with severe CAP in otherwise healthy children, and could be considered markers of disease severity in children with CAP

Khorana score and thromboembolic risk in stage II-III colorectal cancer patients: a post hoc analysis from the adjuvant TOSCA trial

The risk of venous thromboembolic events (VTE) during adjuvant chemotherapy for colorectal cancer (CRC) is unknown. We aim to evaluate if the Khorana score (KS) can predict this risk, and if it represents a prognostic factor for overall survival (OS) through a post hoc analysis of the phase III TOSCA trial of different durations (3- versus 6-months) of adjuvant chemotherapy

Long-term effects of bilateral subthalamic nucleus deep brain stimulation on gait disorders in Parkinson's disease: a clinical-instrumental study

Objective: To assess the long-term effects of bilateral subthalamic nucleus deep brain stimulation (STN-DBS) on gait in a cohort of advanced Parkinson's Disease (PD) patients. Methods: This observational study included consecutive PD patients treated with bilateral STN-DBS. Different stimulation and drug treatment conditions were assessed: on-stimulation/off-medication, off-stimulation/off-medication, and on-stimulation/on-medication. Each patient performed the instrumented Timed Up and Go test (iTUG). The instrumental evaluation of walking ability was carried out with a wearable inertial sensor containing a three-dimensional (3D) accelerometer, gyroscope, and magnetometer. This device could provide 3D linear acceleration, angular velocity, and magnetic field vector. Disease motor severity was evaluated with the total score and subscores of the Unified Parkinson Disease Rating Scale part III. Results: Twenty-five PD patients with a 5-years median follow-up after surgery (range 3-7) were included (18 men; mean disease duration at surgery 10.44 ± 4.62 years; mean age at surgery 58.40 ± 5.73 years). Both stimulation and medication reduced the total duration of the iTUG and most of its different phases, suggesting a long-term beneficial effect on gait after surgery. However, comparing the two treatments, dopaminergic therapy had a more marked effect in all test phases. STN-DBS alone reduced total iTUG duration, sit-to-stand, and second turn phases duration, while it had a lower effect on stand-to-sit, first turn, forward walking, and walking backward phases duration. Conclusions: This study highlighted that in the long-term after surgery, STN-DBS may contribute to gait and postural control improvement when used together with dopamine replacement therapy, which still shows a substantial beneficial effect

Interplay between speech and gait variables in PD patients treated with STN-DBS: a long-term instrumental assessment

Objective: To evaluate correlations between speech and gait parameters in the long-term and under different medication and subthalamic nucleus deep brain stimulation (STN-DBS) conditions in a cohort of advanced Parkinson's Disease (PD) patients. Methods: This observational study included consecutive PD patients treated with bilateral STN-DBS. Axial symptoms were evaluated using a standardized clinical-instrumental approach. Speech and gait were assessed by perceptual and acoustic analyses and by the instrumented timed up and go test (iTUG) respectively. Disease motor severity was evaluated with the total score and subscores of the UPDRS part III. Different stimulation and drug treatment conditions were assessed: on-stimulation/off-medication, off-stimulation/off-medication, and on-stimulation/on-medication. Results: Twenty-five PD patients with a five-year median follow-up after surgery (range 3-7) were included (18 M; disease duration at surgery:10.44 [sd:4.62] years; age at surgery:58.40 [sd:5.73] years). In the off-stimulation/off-medication and on-stimulation/on-medication conditions, patients who spoke louder had also the greater acceleration of the trunk during gait whereas, in the on-stimulation/on-medication condition only, patients with the poorer voice quality were also the worse to perform sit to stand and gait phases of the iTUG. On the contrary, patients with the higher speech rate performed well the turning and walking phases of the iTUG. Conclusions: This study underlines the presence of different correlations between treatment effects of speech and gait parameters in PD patients treated with bilateral STN-DBS. This may allow us to better understand the common pathophysiological basis of these alterations and to develop a more specific and tailored rehabilitation approach for axial signs after surgery
