The importance of religiousness in idiopathic Parkinson's disease (IPD) has been the subject of conflicting research. The impact of religiousness on quality of life and depressive symptoms has also been poorly studied in this population. This study investigated the correlation between religiousness and quality of life in patients with IPD. We evaluated 37 patients with IPD (according to the criteria of the Movement Disorders Society) who were from an outpatient clinic specializing in movement disorders in Brazil. We assessed the patients using the Duke University Religion Index and scales for motor impairment, cognition, quality of life, and depression. Spearman's test was used to check for possible correlations between the different dimensions of religiousness and the clinical variables analyzed. Patients with a worse quality of life and more depressive symptoms showed greater intrinsic religiousness., (© 2024.

The globally accelerating environmental crisis calls for radical changes in the governance of ocean resources towards a more sustainable and socially equitable world. Transdisciplinary sustainability research and networked knowledge-to-action approaches are critical parts of this change. The effective application of such approaches still puzzles social actors (individuals and networks) willing to act in more transformative ways. We conducted twelve participatory network mapping activities to assess the perception of high-level federal government institutional entrepreneurs on the structure and dynamics of an emerging socio-political arena for marine spatial planning (MSP) in Brazil. Our informants, mostly cognizant of their own intra-governmental structures, anticipate the MSP arena to remain self-enclosed, with changes only occurring within the federal government structures in the coming years. Their perceptions were largely conservative, narrow, and unambitious and therefore unfit to generate regime transformations. The limited awareness of response capacities beyond the federal government potentially leads to the endurement of the low performance already present in the MSP arena. Results from the participatory network mapping informed a five-step functional ocean governability analysis pointing to key potential contributions to support a critical turn in MSP: 1. envision situated interactional narratives to leverage regime shifts; 2. build a shared understanding of and anticipating transformative coevolutionary dynamics; 3. build awareness of the potential synergies among disparate but innovative area-based responses; 4. specify inter-network-based limitations and the necessary changes underpinning potential leaps in performance levels of ocean governance orders; 5. make power asymmetries explicit to stir structurally tailored strategic action by less influential groups. We discuss the potential role of inter-network strategies and actions and how they may confront the symptoms of depoliticized MSP pathways and the risks of it becoming an instrument of further marginalisation and power asymmetry in Brazil., Supplementary Information: The online version contains supplementary material available at 10.1007/s40152-021-00250-1., Competing Interests: Conflict of interestThe authors declare no competing interests., (© The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2021.)

Motor symptoms of Parkinson's disease (PD)-bradykinesia, akinesia, and tremor at rest-are consequences of the neurodegeneration of dopaminergic neurons in the substantia nigra pars compacta (SNc) and dopaminergic striatal deficit. Animal models have been widely used to simulate human pathology in the laboratory. Rodents are the most used animal models for PD due to their ease of handling and maintenance. Moreover, the anatomy and molecular, cellular, and pharmacological mechanisms of PD are similar in rodents and humans. The infusion of the neurotoxin, 6-hydroxydopamine (6-OHDA), into a medial forebrain bundle (MFB) of rats reproduces the severe destruction of dopaminergic neurons and simulates PD symptoms. This protocol demonstrates how to perform the unilateral microinjection of 6-OHDA in the MFB in a rat model of PD and shows the motor deficits induced by 6-OHDA and predicted dopaminergic lesions through the stepping test. The 6-OHDA causes significant impairment in the number of steps performed with the contralateral forelimb.

Background: Cerebral amyloid angiopathy (CAA) is a cerebrovascular disorder caused by progressive deposition of β-amyloid peptides in the walls of small and medium-sized cortical and leptomeningeal vessels. Until today, the prevalence of CAA is unknown in our region., Objective: This study aims to analyze the prevalence of this entity in a specific elderly population in a tertiary hospital in Northeastern Brazil., Methods: A cross-sectional, retrospective study with the enrollment of patients aged 65 or older followed in the neurological outpatient service of the Universidade Federal do Piauí, Brazil, who underwent brain magnetic resonance imaging (MRI) from July 2016 to June 2018., Results: One hundred and seventy-four patients were enrolled, of whom 100 were women (57.4%) and 74, men (42.6%), aged from 65 to 91 years old (median age 73.27). Nine patients were excluded from the study due to unavailability of MRI sequences needed for an appropriate analysis. Out of the 165 remaining patients, 12 (7.2%) had established the diagnosis of CAA, according to the modified Boston criteria., Conclusion: The prevalence of CAA in our study was like those of medical literature, with a progressive age-related increase.

Although motor symptoms in Parkinson's disease (PD) are well established, few studies have described the effects of exergaming on the clinical and functional outcomes of PD., Objectives: To analyze the effectiveness of exergaming in improving functional balance, fatigue, functional exercise capacity and quality of life in PD., Methods: The study population consisted of 20 patients (12 males and 8 females) aged 61 ± 9.11 years allocated into two groups: an exergaming group (EGG) (n = 10) and a conventional exercise, or control, group (CG) (n = 10). The following variables were evaluated: functional balance (Berg Scale), fatigue (Fatigue Severity Scale), functional exercise capacity (Six-Minute Walk Test) and quality of life (PDQ-39 Quality of Life Questionnaire)., Results: RM-ANOVA showed that balance and fatigue differed significantly between time points: balance [F(1.29, 23.33) = 4.16, p = 0.043] and fatigue [F(2,36) = 5.96, p = 0.006]. In both cases post hoc Bonferroni testing revealed an improvement after 12 weeks of exergaming (p = 0.033 and p = 0.000, respectively). However, this benefit was not sustained after 60 days of follow-up for either outcome. There were no differences in functional exercise capacity or quality of life between the two groups after 12 weeks of treatment., Conclusion: Exergaming was effective in enhancing balance and reducing fatigue in PD patients after 12 weeks of treatment, but this benefit was not sustained in the long-term., (Copyright © 2017 Elsevier Ltd.
