Osteoporosis in Parkinson's disease and the role of lean body mass: a cross-sectional study in a Brazilian tertiary center.

Background: Parkinson's disease (PD) is the second most common neurodegenerative illness and has the highest increase rate in recent years. There is growing evidence to suggest that PD is linked to higher osteoporosis rates and risk of fractures. Objective: This study aims to estimate the prevalence and factors associated with osteoporosis as defined by the National Osteoporosis Foundation (NOF) and World Health Organization in patients with mild to moderate PD. Methods: We performed a cross-sectional study at a tertiary public hospital in Fortaleza, Brazil, dating from May 2021 until April 2022. The study sample was comprised of patients with mild to moderate PD who were at least 40 years old and who had the ability to walk and stand unassisted. Bone Mineral Density (BMD) of both the hip (neck of the femur) and the lumbar spine were obtained via properly calibrated Dual Energy X-ray Absorptiometry (DXA) scanning. The FRAX (Fracture Risk Assessment Tool) score was used to determine a person's 10-year risk of major osteoporotic fracture. The Revised European Working Group on Sarcopenia in Older People (EWGSOP 2) was used as a basis to confirm a sarcopenia diagnosis with the following parameters: low muscle strength gauged by handgrip strength and low muscle quantity by DXA. Physical performance was carefully evaluated by using the Short Physical Performance Battery test. Osteoporosis and osteopenia were diagnosed following the NOF guidelines and WHO recommendations. Results: We evaluated 107 patients in total, of whom 45 (42%) were women. The group's mean age was 68 ± 9 years, and the mean disease time span was 9.9 ± 6.0 years and mean motor UPDRS was 43 ± 15. We found that 42.1% and 34.6% of the sample had osteopenia and osteoporosis following NOF criteria, respectively, and 43% and 33.6% following the WHO recommendations. Lower lean appendicular mass was associated to osteopenia and osteoporosis in multinomial logistic regression analysis in both diagnostic criteria. Conclusion: Our findings provide additional evidence for the protective role of lean mass against osteoporosis in patients with PD.

Screening Tools for Sarcopenia in Mild to Moderate Parkinson's Disease: Assessing the Accuracy of SARC-F and Calf Circumference.

BACKGROUND: Parkinson's disease (PD) and sarcopenia share similar pathophysiological mechanisms. OBJECTIVE: Estimate the prevalence of sarcopenia in PD patients and describe clinical and demographic features associated with sarcopenia. METHODS: A cross-sectional study was carried out at a tertiary public hospital in Brazil. A modified HY scale of stage 1 to 3, being at least 40 years old and having the ability to stand and walk unassisted were required for eligibility. We evaluated physical performance and muscle mass using DEXA. RESULTS: The study population comprised 124 patients, of which 53 (42.7%) were women. The mean age and mean disease duration were 65.8±10.5 and 10.1±5.8 years, respectively. The mean handgrip strength of 20.4±6.9 in woman and 34.6±8.4 kg in men. Moreover, 50.8% patients had positive SARC-F, 20% patients had probable sarcopenia, 9.6% confirmed sarcopenia, and 16.8% patients showed low muscle mass quantity measured by DEXA. Lower Levodopa Equivalent Dosage (LED) and calf circumference (CC) were independently associated with confirmed sarcopenia. LLED, higher MDS-UPDRS Part III, and lower MMSE scores were independently associated with probable sarcopenia. The CC demonstrated accuracy to identify PD patients with confirmed sarcopenia with a cut-off of <31 cm in women and <34 cm in men. CONCLUSION: We found low prevalence of confirmed sarcopenia among PD patients. We propose that healthcare providers introduce measuring CC, which is a quick and inexpensive method to assess for sarcopenia in PD patients.

Prevalence of characteristics associated with sarcopenia in elders: a cross-sectional study.

OBJECTIVES: to identify the prevalence and characteristics associated with sarcopenia in elders in Primary Health Care Units. METHODS: cross-sectional study with 384 elders. To evaluate sarcopenia, we measured: strength and muscle mass, and physical performance. The elderly were classified as having: probable sarcopenia; sarcopenia; or severe sarcopenia. The chi-squared test and the multinomial logistic regression method were used. RESULTS: the prevalence of probable sarcopenia was 25.52%; of sarcopenia, 11.98%; and of severe sarcopenia, 9.90%. Probable sarcopenia is 1.75 times more prevalent in men; osteoporosis is 2.16 times more prevalent in people with severe sarcopenia; polypharmacy is 1.57 times more likely in individuals with probable sarcopenia; and calf circumference below 31 cm is 2.24 times more likely in patients with sarcopenia and 2.19 times more likely in patients with severe sarcopenia. CONCLUSIONS: the highest prevalence was of probable sarcopenia, and the characteristics associated with sarcopenia were sex, osteoporosis, polypharmacy, overweight, obesity, and calf circumference.

Cognitive Dysfunction Biomarkers in Patients With Rheumatoid Arthritis: A Systematic Review.

BACKGROUND/OBJECTIVES: During the last years, a growing number of studies have investigated the link between cognitive dysfunction and rheumatoid arthritis (RA), highlighting the potential pathogenic role of several clinical, psychological, and biological factors. We aimed to investigate serological and cerebrospinal fluid biomarkers in humans and its association with cognitive dysfunction in patients with RA. METHODS: We performed a systematic review using PRISMA (Preferred Reported Items for Systematic Reviews and Meta-analysis) protocol. A systematic search was conducted in the PubMed/MEDLINE, EMBASE, LILACS, Scopus, and Google Scholar databases from inception up to November 2021. The inclusion criteria for studies were defined based on the participants involved, type of exposure, type of comparison group, outcome of interest, and study design. RESULTS: Five original studies were included, which provided data from 428 participants. Among plasma proteins, SHH was increased and TTR was reduced in patients with mild cognitive impairment; anti-myelin basic protein and anti-myelin oligodendrocyte glycoprotein negatively correlated with memory, executive function, and attention. S100ß negatively correlated with memory and executive functions; some lymphocyte subpopulations positively correlated with attention, memory, and executive functions. Interleukin 2 [IL-2], IL-4, IL-6, and tumor necrosis factor α negatively correlated with memory and positively correlated with executive functions. Interleukin 1ß negatively correlated with global cognitive dysfunction and positively correlated with logical thinking. Interleukin 10 and brain-derived neurotrophic factor negatively correlated with memory. CONCLUSION: Despite the relative scarcity of studies on this subject and the heterogeneity of results, we identified possible biomarkers for cognitive deficits in the RA population. Further longitudinal studies are warranted to clarify these associations and the establishment of possible biomarkers for cognitive deficits in RA.

Educational disparities in Brazil may interfere with the cognitive performance of Parkinson's disease patients / As disparidades educacionais brasileiras podem interferir na performance cognitiva de pacientes com doença de Parkinson

ABSTRACT. The prevalence of cognitive impairment in Parkinson's disease (PD) is about 20% to 60%. The Mini-Mental Status Examination (MMSE) is the most used cognitive screening test. Objective: To evaluate the influence of clinical and demographic characteristics, specifically the education level, on the MMSE score in PD patients of a northeast Brazilian sample. Methods: We performed a cross-sectional study of 198 PD patients at a Movement Disorders outpatient clinic in Fortaleza, CE, Brazil. Participants were assessed by detailed clinical history, modified Hoehn and Yahr staging (HY), geriatric depression scale (GDS) and MMSE. Results: We found that 68% of patients had MMSE scores below the Brazilian thresholds, which were based in Brucki et al. study (2003). There was a statistically significant difference in the bivariate analysis between educational level and cut-off classification for MMSE. More years of formal schooling were associated with more patients scoring below threshold. We found that 75%, 68.8%, and 79.7% of individuals with more than 11, 9 to 11, and 4 to 8 years of formal schooling, respectively, were below the suggested Brazilian Brucki's threshold. GDS and age were negatively correlated with total MMSE and all its domains. There was no correlation between disease duration and MMSE. Subjects with hallucinations had lower scores. Conclusion: Most of the sample had lower performance according to Brazilian thresholds, but there was no control group and no neuropsychological test in this study. Further studies in northeast Brazil are needed to review MMSE cut-off values.

RESUMO. A prevalência de comprometimento cognitivo na doença de Parkinson (DP) é de cerca de 20 a 60%. O Miniexame do Estado Mental (MEEM) é o teste de rastreio cognitivo mais utilizado. Objetivo: Avaliar a influência de características clínicas e demográficas, especificamente a escolaridade, no escore do MEEM em pacientes com DP de uma amostra do nordeste brasileiro. Métodos: Realizamos um estudo transversal com 198 pacientes com DP em um ambulatório de Distúrbios do Movimento em Fortaleza. Os participantes foram avaliados por história clínica detalhada, estadiamento modificado de Hoehn e Yahr (HY), escala de depressão geriátrica (EDG) e MEEM. Resultados: Encontramos 68% dos pacientes com escores do MEEM abaixo dos limiares brasileiros baseados em estudo de Brucki et al. (2003). Houve diferença estatisticamente significativa na análise bivariada entre a escolaridade e a classificação de corte para o MEEM. Mais anos de escolaridade foram associados a mais pacientes com pontuação abaixo do limiar. Constatamos que 75, 68,8 e 79,7% dos indivíduos com mais de 11, nove a 11 e quatro a oito anos de escolaridade, respectivamente, estavam abaixo dos limiares sugeridos pelo estudo brasileiro de Brucki et al. (2003). A EDG e a idade correlacionaram-se negativamente com o MEEM total e todos os seus domínios. Não houve correlação entre a duração da doença e o MEEM. Indivíduos com alucinações tiveram pontuações mais baixas. Conclusão: A maioria da amostra apresentou desempenho inferior aos limiares, mas não houve grupo controle e nem teste neuropsicológico neste estudo. Mais estudos no nordeste do Brasil são necessários para revisar os valores de corte do MEEM.

Telehealth for Parkinson disease patients during the COVID-19 pandemic: the TeleParkinson study.

BACKGROUND: Telemedicine allows Parkinson disease (PD) patients to overcome physical barriers to access health care services and increases accessibility for people with mobility impairments. OBJECTIVE: To investigate the feasibility indicators of a telehealth intervention for PD patients, including patient recruitment, attendance, technical issues, satisfaction, and benefits on levels of physical activity and sleep. METHODS: We conducted a single-center, single-arm study of telehealth video consultations using WhatsApp (Meta Platforms, Inc., Menlo Park, CA, USA). Also, we collected the feasibility indicators as the primary endpoints. All the patients in the study were previously evaluated in person by the same team. RESULTS: Patient recruitment, attendance, and technical issues rates were 61.3%, 90.5%, and 13.3%, respectively, with good scores of patient acceptance and satisfaction with the study intervention. The telehealth intervention improved physical activity, including the number of walks for at least 10 continuous minutes (p = 0.009) and the number of moderate-intensity activities lasting at least 10 continuous minutes (p = 0.001). The Pittsburgh sleep quality index (PSQI) scores also improved for one of its components: perceived sleep duration (p < 0.001) and for total Pittsburgh score (p < 0,001). The average travel time saving was 289.6 minutes, and money-saving was R$106.67 (around USD 18; almost 10% of the current minimum wage in Brazil). CONCLUSIONS: Direct-to-patient telehealth video consultations proved to be feasible and effective and had a positive impact on physical activity levels and sleep in PD patients.

ANTECEDENTES: A telemedicina permite que pacientes com doença de Parkinson (DP) superem barreiras físicas para acessar serviços de saúde e aumenta a acessibilidade para pessoas com mobilidade reduzida. OBJETIVO: Investigar indicadores de viabilidade de uma intervenção em telessaúde para pacientes com DP, incluindo recrutamento, atendimento, aderência, problemas técnicos, satisfação e benefícios nos níveis de atividade física e sono. MéTODOS: Foi conduzido um estudo de centro e braço únicos baseado em consultas por telessaúde com utilização do WhatsApp (Meta Platforms, Inc., Menlo Park, CA, EUA). Foram calculados indicadores de viabilidade como desfechos primários. RESULTADOS: As taxas de recrutamento, atendimento e problemas técnicos foram 61,3%, 90,5% e 13,3%, respectivamente, com bons escores de aceitação e satisfação com a intervenção. A intervenção melhorou os níveis de atividade física, incluindo o número de passos por pelo menos 10 minutos contínuos (p = 0,009) e o número de atividades intensas e moderadas com duração de pelo menos 10 minutos contínuos (p = 0,001). O Índice de Qualidade do Sono de Pittsburgh melhorou nos seguintes componentes: duração percebida do sono (p < 0,001) e escore total (p < 0,001). A média do tempo de viagem médio poupado foi de 289,6 minutos, e a economia financeira foi de R$ 106,67 reais (por volta de USD 18; quase 10% do salário mínimo atual do Brasil). CONCLUSõES: As consultas por vídeo provaram ser viáveis e efetivas, com impacto positivo nos níveis de atividade física e sono de pacientes com DP.

Falls in Parkinson's disease: the impact of disease progression, treatment, and motor complications.

The prevalence of Parkinson's disease (PD) tends to increase worldwide in the coming decades. Thus, the incidence of falls is likely to increase, with a relevant burden on the health care system. Objective: The objective of this study was to evaluate clinical factors and drug use associated with falls in PD patients. Methods: We conducted a cross-sectional study at the Movement Disorders outpatient clinic of a tertiary hospital in Northeast Brazil. We performed structured interviews to collect sociodemographic and clinical data. Functional capacity was assessed using the Schwab and England Activities of Daily Living Scale and the modified Hoehn and Yahr Staging Scale. We divided the study sample into non-fallers (no falls) and fallers (≥1 fall), and non-recurrent (≤1 fall) and recurrent fallers (>1 fall). Results: The study population comprised 327 PD patients (48% women), with a mean age of 70 years. The mean disease duration was 9.9±6.9 years. The most prevalent comorbidities were depression (47.2%), hypertension (44.0%), and type 2 diabetes mellitus (21.5%). The logistic regression analysis revealed that hallucinations, amantadine, and catechol-O-methyltransferase inhibitors (entacapone) were independently associated with falls in PD patients. Also, hallucinations, dyskinesia, and the use of amantadine were independently associated with recurrent falls. Conclusions: Health care providers play an essential role in fall prevention in PD patients, particularly by identifying older adults experiencing dyskinesia and visual hallucinations. Prospective studies should investigate the use of amantadine as a risk factor for falls in PD patients.

Estima-se aumento na prevalência da doença de Parkinson (DP) em todo o mundo nas próximas décadas. Dessa forma, espera-se também aumento na incidência de quedas e seu impacto no sistema de saúde. Objetivo: O objetivo deste estudo foi avaliar fatores clínicos e medicamentos associados a quedas em pacientes com DP. Métodos: Trata-se de um estudo observacional transversal, realizado no ambulatório de Distúrbios do Movimento de hospital terciário no Brasil. Os dados sociodemográficos e clínicos foram coletados por meio de entrevista estruturada. A capacidade funcional foi avaliada pela Escala de Atividades de Vida Diária de Schwab e England e o estadiamento por Hoehn e Yahr modificado. A amostra foi dividida em não caidores (0 quedas) e caidores (≥1 queda) e não caidores recorrentes (≤1 queda) e caidores recorrentes (>1 queda). A informação sobre o número de quedas nos últimos seis meses foi confirmada com familiares e cuidadores. Resultados: A população do estudo foi de 327 pacientes (48% mulheres), com idade média de 70 anos e duração média da doença de 9,9±6,9 anos. As comorbidades mais prevalentes foram depressão (47,2%), hipertensão (44%) e diabetes mellitus tipo 2 (21,5%). A análise de regressão logística revelou que alucinações visuais, uso de amantadina e uso de entacapona foram independentemente associadas a quedas. Alucinações visuais, discinesia e uso de amantadina foram independentemente associados a quedas recorrentes neste estudo. Conclusões: Os profissionais de saúde desempenham um papel importante na prevenção de quedas em pacientes com DP, principalmente idosos que apresentam discinesia e alucinações visuais. Estudos prospectivos da amantadina devem ser realizados para investigar sua associação com quedas em pacientes com DP.

Feasibility indicators of telemedicine for patients with dementia in a public hospital in Northeast Brazil during the COVID-19 pandemic.

BACKGROUND: The use of telemedicine has become a fundamental tool in healthcare in recent years, especially at times of Covid-19 pandemic. Currently, there are several telemedicine tools that are simple, inexpensive, and effective means of communication. This article aims to describe indicators of feasibility including patient recruitment, attendance, discomfort (internet connection issues and/or noncompliant patient behavior), satisfaction, and travel time and cost savings of virtual telemedicine consultations for patients with dementia. METHODS: The study was conducted at the Geriatrics Department of Hospital Universitário Walter Cantídio (HUWC) in Fortaleza, Brazil, between May 1st and December 31, 2020. The eligibility criteria included previous diagnosis of dementia syndrome and receiving care at the hospital's dementia outpatient clinic in face-to-face consultations in the preceding 12 months. Patients were excluded if they did not feel comfortable with virtual consultations, did not have the required communication technology available or their caregiver was not available to attend the remote consultation. The patients were recruited from the outpatient dementia clinic's medical appointment scheduling list. The intervention was designed as a one-time consultation and it included treatment approaches and health promotion recommendations. RESULTS: Patient recruitment, attendance and discomfort rates were 85.5%, 97.7% and 9.4%, respectively. To attend face-to-face visits, they reported an average travel time (including the consultation) of 233.21 minutes and average total cost of 60.61 reais (around USD 11). The study intervention was well accepted among the patients and their caregivers with 97.6% being satisfied. Many were happy to avoid long waits in crowded medical waiting rooms and the risk of covid-19 contagion. CONCLUSIONS: We found good recruitment, attendance, and acceptance rates of remote care for the follow-up of dementia patients as well as low discomfort rates. TRIAL REGISTRATION: Brazilian Trial Registry (REBEC) RBR-9xs978.

Clinical correlates of sarcopenia and falls in Parkinson's disease.

BACKGROUND: Sarcopenia is a complex and multifactorial geriatric condition seen in several chronic degenerative diseases. This study aimed to screen for sarcopenia and fall risk in a sample of Parkinson's disease (PD) patients and to investigate demographic and clinical factors associated. METHODS: This is a cross-sectional study. We evaluated 218 PD patients at the Movement Disorders Clinic in Fortaleza, Brazil, and collected clinical data including experiencing falls in the six months prior to their medical visit. Probable sarcopenia diagnosis was confirmed by using a sarcopenia screening tool (SARC-F questionnaire) and the presence of low muscle strength. RESULTS: One hundred and twenty-one patients (55.5%) were screened positive for sarcopenia using the SARC-F and 103 (47.4%) met the criteria for probable sarcopenia. Disease duration, modified Hoehn and Yahr stage, Schwab and England Activities of Daily Living Scale score, levodopa equivalent dose, probable sarcopenia and positive SARC-F screening were all associated with experiencing falls. Disease duration, lower quality of life and female gender were independently associated with sarcopenia. Experiencing falls was significantly more frequent among patients screened positive in the SARC-F compared to those screened negative. CONCLUSIONS: Sarcopenia and PD share common pathways and may affect each other's prognosis and patients' quality of life. Since sarcopenia is associated with lower quality of life and increased risk of falls, active case finding, diagnosis and proper management of sarcopenia in PD patients is essential.

Prevalence of functional cognitive impairment and associated factors in Brazilian community-dwelling older adults.

The identification of the prevalence of cognitive impairment and associated factors among older adults is important in countries facing rapid demographic transition, given the significant implications for public policy and health planning. OBJECTIVE: To determine the prevalence of functional cognitive impairment (FCI) and associated factors in Brazilian community-dwelling older adults. METHODS: A cross-sectional study involving 461 elderly subjects residing in Fortaleza city, Ceará was conducted. Cognitive assessment was performed using three tests: the MMSE (Mini-Mental State Examination), VF (Verbal Fluency) and CT (Clock Test). The functional capacity evaluation was based on a survey of 21 basic and instrumental activities of daily living (ADLs). Cognitive impairment was defined by MMSE cut-off points adjusted for literacy. Functional impairment was defined as dependency to carry out more than four ADLs. RESULTS: The prevalence of FCI was 13.64% (95% CI: 10.33 to 16.64%). FCI was proportionally associated with age with OR=2.24 (95% CI: 1.04 to 4.79) for individuals aged 70 to 79 years and OR=8.27 (95 % CI: 4.27 to 16.4) for those aged 80 to 100 years. FCI was associated with self-reported diseases including hypertension OR=2.06 (95% CI: 1.17 to 3.65), stroke OR=2.88 (95% CI: 1.66 to 5.00) and acute myocardial infarction OR=2.94 (95% CI: 1.59 to 5.42). The occurrence of FCI was proportionally correlated with the number of drugs used. CONCLUSION: Functional cognitive impairment is a prevalent condition in Brazilian community-dwelling older adults and its occurrence is associated with age, number of drugs used, and vascular morbidities.

A identificação da prevalência de déficit cognitivo, e fatores associados, é importante, dadas as implicações significativas para as políticas públicas e planejamento em saúde. OBJETIVO: Determinar a prevalência de CCF e fatores associados em idosos de uma área urbana brasileira. MÉTODOS: Estudo transversal envolvendo 461 idosos residentes em uma área urbana de Fortaleza, Ceará. Foi aplicado um questionário socioeconômico e de saúde e realizou-se avaliação cognitiva através de três testes de rastreio: Miniexame do Estado Mental (MEEM), FV (Fluência Verbal) e TR (Teste do Relógio). A avaliação da capacidade funcional foi feita por um questionário de 21 atividades da vida diária. Comprometimento cognitivo foi definido pelo comprometimento no MEEM ajustado para escolaridade. Comprometimento funcional foi definido pela incapacidade para mais de 4 AVDs. RESULTADOS: A prevalência de CCF foi de 13,64% (IC 95%: 10,33-16,64%). CCF foi proporcionalmente associado à idade: razão de chances (RC) 2,24 (IC95%: 1,04-4,79) para 70 a 79 anos e RC 8,27 (IC 95%: 4,27-16,4) para 80 a 100 anos. CCF apresentou associação significante com doenças autorreferidas: hipertensão arterial sistêmica apresentou RC 2,06 (IC 95%: 1,17-3,65), acidente vascular cerebral de 2,88 (IC 95%: 1,66-5,00) e infarto agudo do miocárdio de 2,94(IC 95%: 1,59-5,42). A ocorrência de CCF correlacionou-se com maior número de medicamentos usados. CONCLUSÃO: O CCF é condição comum entre os idosos no Brasil e sua ocorrência está associada à idade, ao número de fármacos utilizados e às morbidades vasculares.
