Objective The Parkinson Anxiety Scale (PAS) was developed to measure the severity of anxiety symptoms in patients with Parkinson’s disease (PD), and it has not yet been adapted and validated in Portuguese. Thus, this study evaluated the reliability and validity of a translated and adapted version of the PAS for the Brazilian population of PD patients. Methods The Parkinson Anxiety Scale – Brazilian Version (PAS-BV) was completed by 55 patients with PD. The reliability (test-retest reliability, interrater reliability and internal consistency) and construct validity of the PAS-BV were assessed by comparing it with the Beck Anxiety Inventory (BAI), the Parkinson’s Disease Fatigue Scale (PFS) and the Unified Parkinson Disease Rating Scale (UPDRS) part III. Results Patients with PD had an average age of 64.51 ± 9.20 years and had PD for an average of 6.98 ± 5.02 years. The reliability of the PAS-BV was 0.83, and the intraclass correlation coefficient (ICC) (retest-test) was 0.88. The scale presented good convergent validity with the BAI (rs = 0.82, p < 0.05). It also presented good divergent validity with the PFS (rs = 0.24, p > 0.05) and the UPDRS part II (rs = -0.10, p > 0.05), part III (rs = -0.21, p > 0.05), and part IV (rs = 0.03, p > 0.05), as indicated by the absence of significant correlations. However, there was a significant correlation between the PAS-BV and part I of the UPDRS (rs = 0.67, p < 0.05). Conclusion The PAS-BV presents substantial reliability and validity for patients with PD without dementia.

The aim of this meta-analysis was to investigate the effects of high levels of physical activity (in elite athletes) and sedentary lifestyle on telomere length. Our meta-analysis was carried out using the following electronic databases: PubMed, Cochrane Library, LILACS, Science Direct and EBSCO. After study selection, nine articles were included in our meta-analysis. All of the included subjects were elite athletes (with experience in national or international competitions) or sedentary subjects, which served as the control group. The analysis showed that elite athletes (n = 306) had longer telomeres (P = 0.001) compared with the control group (n = 322). The difference in the standardized means was 0.91 (95% CI = 0.43–1.33; I2 83.4% P value for heterogeneity = 0.001), favoring the athlete group. The analysis of the funnel plot did not detect any risk of publication bias in the studies that reported differences in means. Our results suggest that high level chronic physical training may provide protective effects on telomere length.

The purpose of this study was to evaluate the effects of resistance training alone on the systolic and diastolic blood pressure in prehypertensive and hypertensive individuals. Our meta-analysis, followed the guidelines of PRISMA. The search for articles was realized by November 2016 using the following electronic databases: BIREME, PubMed, Cochrane Library, LILACS and SciELO and a search strategy that included the combination of titles of medical affairs and terms of free text to the key concepts: 'hypertension' 'hypertensive', 'prehypertensive', 'resistance training', 'strength training', and 'weight-lifting'. These terms were combined with a search strategy to identify randomized controlled trials (RCTs) and identified a total of 1608 articles: 644 articles BIREME, 53 SciELO, 722 PubMed, 122 Cochrane Library and 67 LILACS. Of these, five RCTs met the inclusion criteria and provided data on 201 individuals. The results showed significant reductions for systolic blood pressure (-8.2 mm Hg CI -10.9 to -5.5;I2: 22.5% P valor for heterogeneity=0.271 and effect size=-0.97) and diastolic blood pressure (-4.1 mm Hg CI -6.3 to -1.9; I2: 46.5% P valor for heterogeneity=0.113 and effect size=-0.60) when compared to group control. In conclusion, resistance training alone reduces systolic and diastolic blood pressure in prehypertensive and hypertensive subjects. The RCTs studies that investigated the effects of resistance training alone in prehypertensive and hypertensive patients support the recommendation of resistance training as a tool for management of systemic hypertension.

Background The progression of Parkinson disease can lead to respiratory muscle weakness, reduced peak expiratory flow and quality of life (QoL). The aim was to evaluate the effects of strength training on levels of respiratory muscle strength, peak expiratory flow and QoL of elderly with Parkinson disease. Methods A total of 28 patients were randomized into one of two groups: the control group (CG) comprised 16 participants, and the strength training group (STG) comprised 12 participants. All subjects maintained the standard pharmacological treatment for Parkinson disease, and the intervention group participated in a 16-week strength training program. The primary outcome was the measurement of respiratory muscle strength. Results The STG showed improved values of maximum inspiratory pressures (36.11±11.82 to 52.94±24.17; P=0.01), maximum expiratory pressures (56.67±22.08 to 71.04±33.71; P=0.03) and QoL (41.75±20.33 to 34±20.92; P=0.0054); there was no significant difference in the peak expiratory flow (336.11±198.04 to 380±229.57; P=0.09). The CG showed significantly decreased values of peak expiratory flow (336.88±183.40 to 279.37±125.12, P=0.02) and non-significant changes in the other variables. Conclusions Sixteen weeks of strength training improves the inspiratory and expiratory muscle strength and QoL of elderly with Parkinson disease. These findings suggest that strength training could be considered an adjunct therapeutic intervention for elderly with Parkinson disease.

BACKGROUND Depression affects up to 40% of individuals with Parkinson's disease (PD). PURPOSE To assess resistance training effects on the depressive symptoms of elderly PD patients. STUDY DESIGN A randomized control study. METHODS Thirty-three patients (aged ≥ 60 years) were randomly divided into two groups: (a) control group: n = 16 and (b) resistance training group (RTG): n = 17. All patients with Parkinson's disease (stage 1-3 on the Hoehn and Yahr scale). The RTG, in addition to maintaining their pharmacological treatments, performed 20 weeks of resistance training. The control group maintained their pharmacological treatments. Depressive symptoms, quality of life, unified Parkinson's Disease scale, and functional capacity were evaluated in both groups. RESULTS The RTG presented a significant reduction (P

Mutações no gene GBA têm sido reportadas em pacientes com doença de Parkinson (DP) em diferentes países, incluindo o Brasil. Com o objetivo de confirmar esse padrão em uma amostra de pacientes com DP provenientes do Norte brasileiro, foi conduzindo esse estudo caso-controle investigando a frequência das duas mutações mais comuns do gene GBA (c.1226A>G; p.N370S e c.1448T>C; p.L444P) em um grupo de 81 pacientes com DP e 81 controles, usando PCR-RFLP e confirmado pelo sequenciamento direto de produtos de PCR. No grupo experimental, três pacientes (3,7%) foram heterozigotos para a mutação c.1226A>G; p.N370S e três (3,7%), para a mutação c.1448T>C; p.L444P Nenhuma das duas mutações foi detectada no grupo controle (p =0,0284). Pacientes com a mutação c.1448T>C; p.L444P demonstraram uma tendência a apresentar os sintomas mais precocemente, porém um número amostrai maior é necessário para confirmar essa observação. Nossos resultados sugerem uma associação entre essas duas mutações no gene GBA e o desenvolvimento de DP na população de pacientes do norte Brasileiro. Mutations of the GBA gene have been reported in patients with Parkinson's disease (PD) from a number of different countries, including Brazil. In order to confirm this pattern in a sample of PD patients from northern Brazil, we conducted a case-control study of the occurrence of the two most common mutations of the GBA gene (c.1226A>G; p.N370S and c.1448T>C; p.L444P) in a group of 81 PD patients and 81 control individuals, using PCR-RFLP, confirmed by the direct sequencing of the PCR products. In the patient group, three patients (3.7%) were heterozygous for the GBA c.1226A>G; p.N370S mutation, and three (3.7%) for GBA c.1448T>C; p.L444P Neither mutation was detected in the control group (p =0.0284). Patients with the c.1448T>C; p.L444P mutation showed a tendency to have an earlier disease onset, but a larger sample number is required to confirm this observation. Our results suggest an association between the GBA c.1226A>G; p.N370S and c.1448T>C; p.L444P mutations and the development of PD in the population of patients from the Northern Brazil.

ResumoA osteoporose é considerada uma doença osteometabólica comum e sua prevalência está aumentando mundialmente. Nesse contexto, a atividade física tem sido usada como ferramenta não farmacológica para prevenir e auxiliar no tratamento dessa doença. O objetivo desta revisão sistemática foi avaliar os efeitos da prática do ciclismo e da natação na densidade mineral óssea (DMO). Esta pesquisa foi feita de acordo com as recomendações do Preferred Reporting Items for Systematic Reviews and Meta‐Analyses. Os estudos foram consultados entre 2004 e 2014, por meio de importantes bases de dados eletrônicas: PubMed®, SciELO® e Lilacs®. Dez pesquisas avaliaram os efeitos do ciclismo sobre a DMO, os resultados demonstraram que nove estudos associaram a prática do ciclismo profissional com baixos níveis de DMO. Outros 18 estudos relataram que a natação não tem efeitos positivos sobre a massa óssea. Conclui‐se que o ciclismo e a natação não causam efeitos positivos na DMO. Assim, não são os exercícios mais indicados para a prevenção e o tratamento da osteoporose.AbstractOsteoporosis is considered a common metabolic bone disease and its prevalence is increasing worldwide. In this context, physical activity has been used as a non‐pharmacological tool for prevention and auxiliary treatment of this disease. The aim of this systematic review was to evaluate the effects of cycling and swimming practice on bone mineral density (BMD). This research was conducted in accordance with the recommendations outlined by the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses. The studies were consulted in the period from 2004 to 2014, through major electronic databases: PubMed®, SciELO® and LILACS®. Ten studies evaluated the effects of cycling on BMD, and the results showed that nine studies have linked the practice of professional cycling with low levels of BMD. Another 18 studies have reported that swimming has no positive effects on bone mass. We conclude that cycling and swimming do not cause positive effects on BMD; thus, these are not the most suitable exercises for prevention and treatment of osteoporosis.

Objective: To assess the effects of resistance training on the anxiety symptoms and quality of life in patients with Parkinson's disease. Methods: Thirty-five elderly patients were randomly divided into two groups: 17 patients in the control group and 18 in the intervention group. All patients maintained standard pharmacological treatment for Parkinson's disease, but the intervention group participated in a 24-week resistance training program. The anxiety symptoms were assessed through the Beck's Anxiety Inventory, and quality of life by the Parkinson's Disease Questionnaire–39. Results: There was a significant reduction in anxiety level and increase in quality of life after 24 weeks of resistance training. Conclusion: The results of the present study indicate that resistance training is an effective intervention in the reduction of anxiety symptoms and improves the quality of life in elderly people with Parkinson's disease.

Background. Recent data have suggested that polymorphisms in the length of the polyalanine tract (polyA) of FOXE1 gene may act as a susceptibility factor for thyroid dysgenesis. The main purpose of this study was to investigate the influence of polyA of FOXE1 gene on the risk of thyroid dysgenesis. Method. A case-control study was conducted in a sample of 90 Brazilian patients with thyroid dysgenesis and 131 controls without family history of thyroid disease. Genomic DNA was isolated from peripheral blood samples and the genotype of each individual was determined by automated sequencing. Results. More than 90% of genotypes found in the group of patients with thyroid dysgenesis and in controls subjects were represented by sizes 14 and 16 polymorphisms in the following combinations: 14/14, 14/16, and 16/16. Genotypes 14/16 and 16/16 were more frequent in the control group, while genotype 14/14 was more frequent in the group of patients with thyroid dysgenesis. There was no difference between agenesis group and control group. Genotype 14/14 when compared to genotypes 14/16 and 16/16A showed an association with thyroid dysgenesis. Conclusion. PolyA of FOXE1 gene alters the risk of thyroid dysgenesis, which may explain in part the etiology of this disease.
