Effects of Intracerebral Aminophylline Dosing on Catalepsy and Gait in an Animal Model of Parkinson's Disease.

Parkinson's disease (PD) is a progressive disorder characterized by the apoptosis of dopaminergic neurons in the basal ganglia. This study explored the potential effects of aminophylline, a non-selective adenosine A1 and A2A receptor antagonist, on catalepsy and gait in a haloperidol-induced PD model. Sixty adult male Swiss mice were surgically implanted with guide cannulas that targeted the basal ganglia. After seven days, the mice received intraperitoneal injections of either haloperidol (experimental group, PD-induced model) or saline solution (control group, non-PD-induced model), followed by intracerebral infusions of aminophylline. The assessments included catalepsy testing on the bar and gait analysis using the Open Field Maze. A two-way repeated-measures analysis of variance (ANOVA), followed by Tukey's post hoc tests, was employed to evaluate the impact of groups (experimental × control), aminophylline (60 nM × 120 nM × saline/placebo), and interactions. Significance was set at 5%. The results revealed that the systemic administration of haloperidol in the experimental group increased catalepsy and dysfunction of gait that paralleled the observations in PD. Co-treatment with aminophylline at 60 nM and 120 nM reversed catalepsy in the experimental group but did not restore the normal gait pattern of the animals. In the non-PD induced group, which did not present any signs of catalepsy or motor dysfunctions, the intracerebral dose of aminophylline did not exert any interference on reaction time for catalepsy but increased walking distance in the Open Field Maze. Considering the results, this study highlights important adenosine interactions in the basal ganglia of animals with and without signs comparable to those of PD. These findings offer valuable insights into the neurobiology of PD and emphasize the importance of exploring novel therapeutic strategies to improve patient's catalepsy and gait.

Impact of Social Isolation on the Physical and Mental Health of Older Adults: A Follow-Up Study at the Apex of the COVID-19 Pandemic in Brazil.

INTRODUCTION: The COVID-19 pandemic has affected people's lives and caused changes in habits. The World Health Organization recommends social isolation as a way of minimizing the risk of contagion of the disease. OBJECTIVE: The aim of the study was to assess the impact of social isolation due to COVID-19 pandemic on the physical and mental health of older adults and to investigate how anthropometric, functional, and clinical aspects are associated with this process. METHODS: Fifty healthy older adults were followed-up during 5 months. The subjects had their physical and mental health assessed during social isolation (pre-vaccine situation) and after the opening of stores and activities in the municipality (post-vaccine situation). Physical evaluation was performed using the 30-s sit and stand test. Participants' mental health was assessed with the Geriatric Depression Scale and the Loneliness Index. In this methodological design, muscle strength, depressive symptoms, and loneliness index were subject to pre-post analyses. In addition, these variables were included as outcomes in linear regression models. Participants' anthropometric, functional, and clinical factors were included as predictors of the statistical model. RESULTS: Participants' scores at baseline were consistent with mild depressive symptoms and low loneliness. The muscle strength of the subjects was appropriate to their ages. After 5 months of social isolation, all variables declined, but with statistical significance only for depressive symptoms (p = 0.017, effect size of 0.11). Anthropometric, functional, and clinical factors explained 42.8% of depressive symptoms, 22.3% of loneliness, and 30.2% of muscle strength in the elderly. DISCUSSION/CONCLUSION: Older adults presented baseline scores consistent with mild depressive symptoms and low loneliness. The muscular strength of the subjects was appropriate for their ages. After 5 months of social isolation, all variables declined. Anthropometric, functional, and clinical factors explained a substantial part of the depressive symptoms, loneliness, and muscular strength in the elderly. Health care professionals should be aware of performing a wide assessment in subjects' lives to ensure better health status.

Effects of Aquatic Physical Exercise on Motor Risk Factors for Falls in Older People During the COVID-19 Pandemic: A Randomized Controlled Trial.

OBJECTIVE: The aim of this study was to assess the effects of aquatic training on motor risk factors for falls in older people during the COVID-19 pandemic. METHODS: A randomized controlled trial was carried out with older people, divided into an aquatic training group (ATG) (n = 24) and a control group (CG) (n = 25). Muscle strength was assessed by the 5-Times Sit-to-Stand Test, mobility by the simple and dual-task Timed Up and Go Test, and postural stability through stabilometric data (force platform). The CG received monthly calls to monitor general health. The ATG carried out training lasting 16 weeks, with two 1-hour sessions per week. RESULTS: Both groups improved muscular strength and cognitive-motor tasks, and they performed a dual task with fewer errors in the secondary task after 16 weeks regardless of the pandemic and COVID-19 diagnosis. There was a significant decrease in the area of center of pressure displacement in the tandem posture with eyes closed in the CG. When analyzing participants who adhered at least 50% to the intervention, the ATG significantly reduced the number of steps on the Timed Up and Go Test performance. Both groups improved muscular strength and cognitive-motor tasks and increased the cognitive task cost. In the CG, there was a significant decrease in the mean amplitude of the anteroposterior center of pressure displacement in the feet together with eyes open. CONCLUSION: We found that aquatic physical exercise presented positive effects on some potentially modifiable motor risk factors for falls (mobility and muscle strength) regardless of the COVID-19 pandemic and COVID-19 diagnosis, especially among people who adhered to the intervention.

Impact of the COVID-19 Pandemic on the Scientific Production of Physical Education Researchers: A Five-Year Follow-Up Study.

The COVID-19 pandemic caused significant changes in society's dynamics, particularly affecting the landscape of education. Research in several areas may have been affected during periods of social restrictions. This study analyzed the curricula of 558 researchers across 27 graduate programs in physical education in Brazil to investigate the potential impact of the COVID-19 pandemic on scientific publications. Researchers' production from 2018 to 2022 underwent a comprehensive analysis, considering the total number of publications, Qualis rank, and journal impact factor. Data were analyzed using chi-squared and Kruskal-Wallis tests. Significance was set at 5%. Overall, the analyzed researchers published a total of 17,932 manuscripts from 2018 to 2022. During the COVID-19 pandemic, there was a decline of 16.4% in the number of articles published (p = 0.001). This decline was similar between men and women (p = 0.603) and was associated with a worsening in Qualis rank (p = 0.001). The number of studies published in journals with impact factors was also affected (p = 0.001). The findings suggest a potential impact of the COVID-19 pandemic on the scientific production of Brazilian researchers in the field of physical education. Funding agencies should consider the challenges associated with the COVID-19 pandemic before evaluating researchers and programs.

Benefits of a Dual-Task Training on Motor and Cognitive Functions in Community-Dwelling Older Adults: A Controlled Clinical Trial.

OBJECTIVE: The aim of the study is to verify the effects of a 3-mo dual-task training on motor and cognitive functions in community-dwelling older adults. DESIGN: In this prospective, single-blinded, controlled clinical trial, a total of 40 participants were allocated to either the experimental or the control (no-exercise) group. The intervention program consisted of a combination of motor and cognitive exercises conducted twice a week on nonconsecutive days. The main outcome measures were postural stability, mobility, fear of falling, and cognitive functions. Multiple analyses of variance were used to assess the impact of the dual-task training. Effect sizes (η 2 p) were reported. Significance was set at 5%. RESULTS: Compared with the control group, participants who underwent the dual-task training showed positive outcomes in terms of postural stability (η 2 p = 0.298, P = 0.020), mobility (η 2 p = 0.285, P = 0.003), and cognitive functions (η 2 p = 0.536, P = 0.001). No significant differences were observed between the groups in terms of the fear of falling ( P = 0.566). CONCLUSIONS: Three-month dual-task training was beneficial for postural control, mobility, and cognitive functions in community-dwelling older adults. Based on the present findings, healthcare professionals should consider incorporating dual-task training into clinical practice.

Effects of horseback riding therapy on quality of life in patients post stroke.

BACKGROUND: Persons with stroke commonly have serious sequelae requiring long-term medical treatment. They often experience distress, and thus improving quality of life (QOL) has been considered a therapeutic objective in addition to prolonging the patient's life. OBJECTIVE: The aim of this study was to analyze the impact of horseback riding therapy (HBRT) on the QOL of individuals with hemiparesis after stroke. METHODS: In this single-blind, randomized, controlled trial, 24 poststroke patients were assigned to the experimental (n = 12) and control (n = 12) groups. The control group participated in a conventional physiotherapy program, whereas the experimental group participated in physiotherapy plus HBRT sessions for 16 weeks. The patients were evaluated by means of the Medical Outcomes Study 36-item Short-Form health survey (SF-36). Data analysis was applied through the use of descriptive and inferential statistics, with a 5% level of significance. RESULTS: Significant improvement was observed in the total score of the SF-36 in the experimental group when compared with the control group. The combination of conventional physiotherapy and HBRT was associated with improvements in functional capacity (P = .02), physical aspects (P = .001), and mental health (P = .04) of the stroke patients. CONCLUSIONS: Supplementation of conventional physiotherapy with HBRT, applied in different contexts, may yield positive QOL outcomes for people with stroke. We recommend that further studies be carried out to clarify the benefits of HBRT applied singly.

Impact of lower urinary tract symptoms in women with multiple sclerosis: an observational cross-sectional study.

BACKGROUND: Lower urinary tract symptoms (LUTS) are common in women with multiple sclerosis. OBJECTIVE: To investigate the impact of LUTS on pelvic floor muscle contraction, sexual function, and quality of life in women with multiple sclerosis. METHODS: Thirty-nine women with relapsing-remitting multiple sclerosis were enrolled in this study. Participants were divided into the presence or not of LUTS. Assessments involved the Expanded Disability Status Scale score, the NEW PERFECT scheme, the Female Sexual Function Index, and the Qualiveen Questionnaire. Statistical procedures involved Student t-tests, chi-squared, and regression analyses (R2). RESULTS: Nineteen women (48.7%) presented LUTS. Women with LUTS were in a more advanced stage of multiple sclerosis (p = .029), presented weaker pelvic muscle contraction (p = .009), less sexual function satisfaction (p = .018), and more limitations in the quality of life (p = .001) than women without LUTS. Regression analyses pointed out that the quality of life and sexual function of women with multiple sclerosis are affected by intercourse pain (R2 = 12.9) and perineal contraction force (R2 = 19.2). CONCLUSION: LUTS affects pelvic floor muscle contraction, sexual function, and quality of life in women with multiple sclerosis. A multi-professional rehabilitation team should assist women with multiple sclerosis, taking special care of LUTS.

Impact of Using Smartphone While Walking or Standing: A Study Focused on Age and Cognition.

BACKGROUND: Using smartphones during a task that requires upright posture is suggested to be detrimental for the overall motor performance. The aim of this study was to determine the role of age and specific aspects of cognitive function on walking and standing tasks in the presence of smartphone use. METHODS: 51 older (36 women) and 50 young (35 women), mean age: 66.5 ± 6.3 and 22.3 ± 1.7 years, respectively, were enrolled in this study. The impact of using a smartphone was assessed during a dynamic (timed up and go, TUG) and a static balance test (performed on a force platform). Multivariate analyses of variance were applied to verify main effects of age, task, estimates of cognitive function and interactions. RESULTS: Compared to young, older individuals exhibited a poorer performance on the dynamic and on the static test (age effect: p = 0.001 for both variables). Dual-tasking with a smartphone had a negative impact on both groups (task effect: p = 0.001 for both variables). The negative impact, however, was greater in the older group (age × task effect: p = 0.001 for both variables). Executive function and verbal fluency partially explained results of the dynamic and static tests, respectively. CONCLUSIONS: The negative impact of using a smartphone while performing tasks similar to daily activities is higher in older compared to young people. Subclinical deficits in distinct aspects of cognitive function partially explain the decreased performance when dual-tasking.

Using the cell phone while standing or walking affects balance and mobility in people with Parkinson's disease.

BACKGROUND: Cell phones are part of peoples' lives. The literature indicates risks when cell phones are used during a secondary motor task. Studies addressing this topic in people with Parkinson's disease are still scarce. OBJECTIVE: To investigate the impact of daily dual tasks with cell phone on balance and mobility in people with Parkinson's disease, compared to healthy control peers. METHODS: Participants with Parkinson's disease and controls underwent three motor tasks: (1) Standing and walking without using a cell phone; (2) Standing and walking while talking on the phone; and (3) Standing and walking while texting messages on the phone. Assessments involved balance and mobility tests. Statistical analysis was performed with multivariate analysis of variance, comparing main effect for group (Parkinson's disease × control), task (using × not using cell phone) and interactions (group × task). Significance was set at 5%. Effect sizes are reported. RESULTS: Participants with Parkinson's disease showed worse balance (p = 0.001, effect size of 0.471) and mobility (p = 0.001, effect size of 0.472) than control peers. The use of cell phone while performing a secondary motor task affected both groups (p = 0.005, effect size of 0.673 for balance and p = 0.001, effect size of 0.549 for mobility). The dual task impact, however, was higher in the Parkinson's disease group (p = 0.009, effect size of 0.407 for mobility). CONCLUSION: Daily dual tasks with cell phones increase imbalance and mobility risks in Parkinson's disease. People should be careful when using their cell phone while standing or walking.

ANTECEDENTES: Aparelhos celulares fazem parte da vida das pessoas. A literatura aponta riscos quando o uso do celular está associado a uma tarefa motora. Estudos abordando esse tema na doença de Parkinson são escassos. OBJETIVO: Investigar o impacto de tarefas-duplas com o celular sobre equilíbrio e mobilidade de pessoas com doença de Parkinson, na comparação com controles saudáveis. MéTODOS: Participantes com e sem doença de Parkinson foram submetidos a três tarefas: (1) Ficar em pé e caminhar sem o celular; (2) Ficar em pé e caminhar enquanto conversa ao celular; e (3) Ficar em pé e caminhar enquanto digita mensagens. As avaliações envolveram testes de equilíbrio e mobilidade. Os procedimentos estatísticos envolveram testes de análise múltipla de variâncias, com análise de efeito principal para os fatores grupo (doença de Parkinson × controle), tarefa (com celular × sem celular) e interação (grupo × tarefa). Significância foi estipulada em 5%. Tamanhos de efeito foram reportados. RESULTADOS: Participantes com doença de Parkinson apresentaram pior equilíbrio (p = 0,001; tamanho do efeito: 0,471) e mobilidade (p = 0,001; tamanho do efeito: 0,472) que controles. O uso do celular afetou ambos os grupos (p = 0,005, tamanho do efeito de 0,673 para equilíbrio e p = 0,001, tamanho do efeito de 0,549 para mobilidade). O impacto da tarefa-dupla, contudo, foi maior no grupo Parkinson (p = 0,009; tamanho do efeito de 0,407 para mobilidade). CONCLUSãO: Tarefas simultâneas com o celular causam desequilíbrio e problemas de mobilidade na doença de Parkinson. As pessoas devem ter cuidado ao utilizar celulares durante atividades em pé e ao caminhar.

Efficacy of Transcranial Direct Current Stimulation (tDCS) on Cognition, Anxiety, and Mobility in Community-Dwelling Older Individuals: A Controlled Clinical Trial.

Transcranial direct current stimulation (tDCS) has gained popularity as a method of modulating cortical excitability in people with physical and mental disabilities. However, there is a lack of consensus on its effectiveness in older individuals. This study aimed to assess the efficacy of a 2-month tDCS program for improving physical and mental performance in community-dwelling older individuals. In this single-blinded, controlled clinical trial, forty-two participants were allocated to one of three groups: (1) the tDCS group, which received, twice a week, 20 min sessions of 2 mA electric current through electrodes placed on the dorsolateral prefrontal cortex; (2) the tDCS-placebo group, which underwent the same electrode placement as the tDCS group but without actual electric stimulation; and (3) the cognitive-control group, which completed crossword puzzles. Main outcome measures were cognition, mobility, and anxiety. Multivariate analyses of variance were employed. Significance was set at 5% (p < 0.05). Regarding the results, no significant benefits were observed in the tDCS group compared with the tDCS-placebo or cognitive-control groups for cognition (p = 0.557), mobility (p = 0.871), or anxiety (p = 0.356). Cognition exhibited positive oscillations during the assessments (main effect of time: p = 0.001). However, given that all groups showed similar variations in cognitive scores (main effect of group: p = 0.101; group × time effect: p = 0.557), it is more likely that the improvement reflects the learning response of the participants to the cognitive tests rather than the effect of tDCS. In conclusion, a 2-month tDCS program with two sessions per week appears to be ineffective in improving physical and mental performance in community-dwelling older individuals. Further studies are necessary to establish whether or not tDCS is effective in healthy older individuals.

Age, motor dysfunction and neuropsychiatric symptoms impact quality of life in multiple sclerosis.

OBJECTIVES: to investigate the impact of age, motor dysfunction and neuropsychiatric symptoms on the quality of life of people with multiple sclerosis in comparison to healthy peers. METHODS: a total of 141 participants were tested in a single session. The assessments were composed by general questionnaires applied in both groups and by specific instruments restricted to multiple sclerosis. Multiple regression models were applied to assess relationships between predictors and outcome. RESULTS: age, motor dysfunction and neuropsychiatric symptoms explained 56.6% of quality of life of the multiple sclerosis group. Age and neuropsychiatric symptoms explained 36.6% of quality of life in the control group. Age impacted more the multiple sclerosis group than the control group. Neuropsychiatric symptoms affected both groups similarly. Motor dysfunction impacted 21.9% of the quality of life in multiple sclerosis. CONCLUSIONS: the predictors explained considerable variance of quality of life in multiple sclerosis, which should guide public health policies.

Risks of Accidents Caused by the Use of Smartphone by Pedestrians Are Task- and Environment-Dependent.

Using smartphones during a task that requires an upright posture can be detrimental for the overall motor performance. The aim of this study was to determine the risks of accidents caused by the use of smartphones by pedestrians while walking in a controlled (laboratory) and a non-controlled (public street) environment. Two hundred and one participants, 100 men and 101 women, all young adults, were submitted to walking activities while texting messages and talking on the phone. The risk of accident was measured by the time and the number of steps necessary to walk a 20 ft distance. Assessments were performed with no external distractors (laboratory) and on a public street with vehicles, pedestrians, lights, and noises. Multivariate analysis of variance tests provided the main effect of task (using × not using smartphone), environment (laboratory × street), sex (men × women), and interactions. Significance was set at 5%. The results showed that using a smartphone while walking demanded a greater number of steps and time to perform the task (main effect of task: 0.84; p = 0.001). The risk of accident was higher on the streets where, due to traffic hazards, pedestrians performed the task faster and with a lower number of steps (the main effect of environment: 0.82; p = 0.001). There was no difference of risks between men and women (main effect of sex: 0.01; p = 0.225), whether in the laboratory or on the street (main effect of sex × environment: 0.01; p = 0.905). The task × environment interaction showed that using a smartphone on the street potentiates risks of accidents of pedestrians (main effect of task × environment: 0.41; p = 0.001). In conclusion, using a smartphone while walking can be risky for pedestrians, especially in a traffic environment. People should avoid using their smartphone while crossing streets.

Pulmonary function and medication effect in mild-stage subjects with Parkinson's disease.

BACKGROUND: Parkinson's disease (PD) causes a series of movement disorders, many of them starting in the early stage. OBJECTIVE: To analyze the pulmonary function of mild-stage subjects with PD and to investigate the effects of levodopa on it. METHODS: We included 21 patients with idiopathic PD and 20 healthy control subjects. The participants were submitted to spirometry and impulse oscillometry assessments. The PD patients were evaluated during the "off" and "on" phases of their anti-PD medication, which was was converted to levodopa in an equivalent daily dose. A statistical analysis was performed with cross-sectional (PD patients "off" medication versus controls) and paired (PD patients "off" medication versus PD patients "on" medication) tests. The effect of levodopa was calculated with partial Eta-squared (η2 ρ). Significance was set at 5%. RESULTS: The PD patients presented normal values in the impulse oscillometry. Regarding spirometry, the results indicated an incipient obstructive ventilatory disorder in the PD group - confirmed by patients' flow-volume curves. The PD patients received a daily dose of 354.7 ± 148.2 mg of levodopa. The paired analyses showed a small effect of anti-PD medication on pulmonary parameters (η2 ρ = 0.197 for spirometry and η2 ρ= 0.043 for impulse oscillometry). CONCLUSION: Patients with PD in the mild stage of the disease present pulmonary compliance and resistance compatible with normal parameters. The differences regarding the spirometric results indicate an incipient obstructive ventilatory disorder in patients with PD. Levodopa had small effect on pulmonary function in the mild stage of the disease.

ANTECEDENTES: A doença de Parkinson (DP) causa uma série de distúrbios do movimento, muitos deles se desenvolvendo na fase inicial. OBJETIVO: Analisar função pulmonar de pessoas com DP em estágio leve e investigar o efeito da levodopa nesse processo. MéTODOS: Vinte e um participantes com DP idiopática e vinte controles saudáveis foram incluídos na pesquisa. Todos os sujeitos foram submetidos a avaliações de espirometria e oscilometria de impulso. Participantes com DP foram avaliados nas fases 'on' e 'off' de medicação anti-parkinsoniana. A medicação dos pacientes foi convertida em dose diária de levodopa. A análise estatística foi realizada com testes transversais (Parkinson na fase 'off' da medicação vs controles) e pareados (Parkinson nas fases 'off' vs 'on' da medicação). O efeito da levodopa foi calculado pelo eta ao quadrado parcial (η2 ρ). Significância foi estipulada em 5%. RESULTADOS: Pacientes com DP apresentaram valores normais na oscilometria de impulso. Na espirometria, os resultados indicaram uma desordem ventilatória obstrutiva incipiente no grupo DP ­ confirmada pelas curvas fluxo-volume dos pacientes. Pacientes com DP receberam uma dose diária de 354,7 ± 148,2 miligramas de levodopa. Análises pareadas mostraram baixo impacto da medicação anti-parkinsoniana nos parâmetros pulmonares (η2 ρ = 0,197 na espirometria e η2 ρ = 0,043 na oscilometria de impulso). CONCLUSãO: Pacientes com DP na fase leve apresentam complacência e resistência pulmonares compatíveis com parâmetros normais. Diferenças espirométricas indicam distúrbio ventilatório obstrutivo incipiente em pacientes com DP. A administração de levodopa apresentou baixo efeito na função pulmonar na fase leve da doença.

Accuracy and Sensitivity of Clinical Parameters in Predicting Successful Extubation in Patients with Acute Brain Injury.

BACKGROUND: Brain injuries are frequent causes of intubation and mechanical ventilation. The aim of this study was to investigate the accuracy and sensitivity of clinical parameters in predicting successful extubation in patients with acute brain injury. METHODS: Six hundred and forty-four patients assisted at a high-complexity hospital were recruited. Patients were divided as for successful or failed extubation. The VISAGE score, maximum inspiratory and expiratory pressures, peak cough flow, and airway occlusion pressure at 0.1 s were used as predictors. Logistic regression analyses using ROC-curve identified values of accuracy and sensitivity. The Hosmer-Lemeshow test and the stepwise method calibrated the statistical model. RESULTS: VISAGE score (odds ratio of 1.975), maximum inspiratory pressure (odds ratio of 1.024), and peak cough flow (odds ratio of 0.981) are factors consistent in distinguishing success from failure extubation. The ROC curve presented an accuracy of 79.7% and a sensitivity of 95.8%. CONCLUSIONS: VISAGE score, maximum inspiratory pressure and peak cough flow showed good accuracy and sensitivity in predicting successful extubation in patients with acute brain injury. The greater impact of VISAGE score indicates that patients' neurological profile should be considered in association with ventilatory parameters in the decision of extubation.

Activity limitations in leprosy and their association to cognition and neuropsychiatric symptoms.

OBJECTIVES: to analyze activity limitations in patients with leprosy and their association to cognition and neuropsychiatric symptoms. METHODS: this cross-sectional design study included sixty patients with multibacillary leprosy assisted at a reference center. Participants were divided according to their physical disability and submitted to instruments assessing daily activities (basic and instrumental), cognitive functions, and neuropsychiatric symptoms. The order of the instruments was random to avoid any interference of test sequence on the results. RESULTS: fifty-five percent of the participants presented physical disabilities. All patients were independent in performing basic activities but sixty-six percent presented difficulties in performing instrumental activities. Cognitive decline and neuropsychiatric symptoms were seen in advanced stages of the disease, but they were more associated to patient age than to leprosy. CONCLUSIONS: leprosy patients presented physical disabilities and difficulties in performing instrumental daily activities. Cognitive decline and neuropsychiatric symptoms were more associated to aging than to leprosy itself.

Architectural and communications barriers to access to primary health care in Brazil: an analysis based on the first national census of primary health care centers, 2012. / Barreiras arquitetônicas e de comunicação no acesso à atenção básica em saúde no Brasil: uma análise a partir do primeiro Censo Nacional das Unidades Básicas de saúde, 2012.

OBJECTIVE: to analyze the results of the National Census of Primary Health Care Centers with regard to architectural and communication barriers in Primary Health Care throughout Brazil. METHODS: this was a cross-sectional study based on data from the first National Census of Primary Health Care Centers conducted between May and October 2012. RESULTS: the Northern region had the lowest rates of adequacy; although the Southeast region had the best rates when compared to the country's other regions, they were nevertheless unsatisfactory, since for many items adequacy was still below 50%; the items relating to accessibility by people with disabilities (5.7 to 34.2%) and/or the illiterate (0.1 to 27.4%) had very low scores. CONCLUSION: the majority of services evaluated had architectural and communication barriers, hindering access to health services by disabled, illiterate or elderly people; the importance of allocating resources to reduce iniquities and improve access is stressed.

Psychopathological features in patients with Parkinson's disease and related caregivers' burden.

BACKGROUND: Along with classical motor disorders in Parkinson's disease (PD), psychopathological features frequently co-occur, which may increase the caregiver's burden. AIMS: To identify the profile of psychopathological symptoms in patients with PD and the impact imposed by this condition on the caregiver's burden. SUBJECTS: Fifty patients with idiopathic PD seen consecutively at the Movement Disorder Outpatient Clinic at the Hospital of State University of Campinas, Brazil, and their 50 respective caregivers were studied. METHODS: The 50 patients with PD were divided into three groups according to the respective psychiatric diagnosis received (depression: N = 17, dementia: N = 13 and non-depressed and non-demented: N = 20). We divided the caregivers into three groups according to the mental condition of their patients. To assess the mental condition of patients and the caregiver's burden, and to correlate those psychopathological features found with clinical features of PD, we applied the Neuropsychiatric Inventory (NPI). RESULTS: Patients with dementia presented the highest NPI scores of psychopathological symptoms (26.4), followed by patients with depression (24.9). Non-depressed and non-demented patients revealed fewer symptoms (7.2). Caregivers' burden was found to be proportional to the degree of patients' symptomatology. CONCLUSION: Patients with dementia presented more severe motor impairment and lower functionality, followed by patients with depression and those non-demented, non-depressed. Psychotic symptoms, agitation, aberrant motor behaviours and sleep disturbances were higher in dementia group. Neuropsychiatric disturbances correlated with caregiver's burden, which was highest in patients with dementia.

A Controlled Clinical Trial on the Effects of Exercise on Cognition and Mobility in Adults With Multiple Sclerosis.

OBJECTIVE: The aim of the study was to investigate the effects of a 6-mo exercise program on cognition and mobility in participants with multiple sclerosis. DESIGN: This is a prospective, single-blind, controlled clinical trial. SETTING: A community rehabilitation program within a large metropolitan health service. PARTICIPANTS: Twenty-eight patients with multiple sclerosis were referred for outpatient rehabilitation. INTERVENTIONS: Participants were allocated to one of two groups and undertook a cognitive-motor exercise program or monitoring (control group). MAIN OUTCOME MEASURES: Cognition and mobility were the main outcome measures. Cognition was evaluated using the Mini-Mental State Examination and the Frontal Assessment Battery. Mobility was assessed with the Timed Get Up and Go test, applied with and without dual task distractors. RESULTS: The findings showed benefits provided by exercise on cognition and mobility. Differently, participants of the control group did not have significant changes in cognition scores after 6 mos of follow-up and had a worse performance in mobility tests. CONCLUSION: Six months of exercise provided benefits to cognition and mobility in adults with multiple sclerosis.

Differential Acute Effect of High-Intensity Interval or Continuous Moderate Exercise on Cognition in Individuals With Parkinson's Disease.

BACKGROUND: People with Parkinson's disease (PD) present cognitive impairments, which deteriorate their quality of life and increase disability. Acute aerobic exercise has demonstrated favorable effects on cognitive function in healthy neurologically individuals, but these effects have a dose-response relationship. Therefore, this study aimed to investigate the acute effects of high-intensity interval training (HIIT) versus continuous moderate-intensity training (MICT) on cognitive functions in people with PD. METHODS: A total of 14 individuals with PD performed cognitive tests, before and after 3 sessions-control session (CON), HIIT, and MICT. HIIT and MICT were performed on a stationary bicycle. HIIT consisted of a 25-minute exercise of high-intensity intervals (1 min) alternated with moderate-intensity intervals (2 min). MICT consisted of a 30-minute moderate-intensity exercise. CON was 30 minutes of seated resting. The cognitive parameters were compared by a mixed-model analysis for repeated measures. RESULTS: Acute effects of exercise were according to its type: MICT-improved immediate auditory memory (P < .01); HIIT-improved immediate auditory memory (P < .02), attention (P < .001), and sustained attention (P < .01); and CON-no effects on cognitive function. CONCLUSIONS: Acute aerobic exercise was able to promote better cognitive performance in people with PD. The effects on cognition were exercise intensity dependent.

Physiotherapy Versus Physiotherapy Plus Cognitive Training on Cognition and Quality of Life in Parkinson Disease: Randomized Clinical Trial.

OBJECTIVE: The aim of the study was to verify the effectiveness of physiotherapy associated with cognitive training to improve cognition and quality of life in individuals with Parkinson disease. DESIGN: This is a randomized clinical trial involving 58 individuals with mild to moderate Parkinson disease, randomly distributed into two groups: motor group and cognitive-motor group. Both groups were assessed for cognition and quality of life at the beginning of the study, at the end of the intervention protocols, and 3 mos after the end of the intervention. The following instruments were used to assess cognition and quality of life: Mini-Mental State Examination, Montreal Cognitive Assessment, Verbal fluency test, Rey Auditory Verbal Learning Test, Cognitive and perceptual assessment by pictures, Trail Making Test, Clock Drawing Executive Test, and Parkinson Disease Quality of Life Questionnaire. The motor group engaged in motor physiotherapy, whereas the cognitive-motor group underwent combined motor physiotherapy with cognitive training. RESULTS: The intragroup analysis revealed that both groups presented improved cognition (memory and visuospatial function domains) and quality of life after execution of the protocols, but without statistically significant intergroup differences. CONCLUSIONS: When comparing the intervention moments, the two treatment approaches used were effective for the outcomes: memory, visuospatial function, and quality of life in both groups.
