RESUMEN
BACKGROUND: An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors. METHODS: This is a cross-sectional study carried out with individuals with atherosclerosis (coronary artery disease, cerebrovascular disease or peripheral arterial disease) recruited from 35 reference centres for the treatment of cardiovascular disease in Brazil. Diet quality was assessed according to the Modified Alternative Healthy Eating Index (mAHEI) and stratified into tertiles. For comparing two groups, the Mann-Whitney or Pearson's chi-squared tests were used. However, for comparing three or more groups, analysis of variance or Kruskal-Wallis was used. For the confounding analysis, a multinomial regression model was used. p < 0.05 was considered statistically significant. RESULTS: In total, 2360 individuals were evaluated: 58.5% male and 64.2% elderly. The median (interquartile range [IQR]) of the mAHEI was 24.0 (20.0-30.0), ranging from 0.4 to 56.0 points. When comparing the odds ratios (ORs) for the low (first tertile) and medium (second tertile) diet quality groups with the high-quality group (third tertile), it was observed that there was an association between diet quality with a family income of 1.885 (95% confidence intervals [CI] = 1.302-2.729) and 1.566 (95% CI = 1.097-2.235), as well as physical activity of 1.391 (95% CI = 1.107-1.749) and 1.346 (95% CI = 1.086-1.667), respectively. In addition, associations were observed between diet quality and region of residence. CONCLUSIONS: A low-quality diet was associated with family income, sedentarism and geographical area. These data are extremely relevant to assist in coping with cardiovascular disease because they enable an assessment of the distribution of these factors in different regions of the country.

This study compares clinical practice and objections to controversial ethical issues among 836 Brazilian resident physicians according to levels of religiousness/spirituality. Residents with low religiousness/spirituality (s/r) believed less in the influence of spirituality on clinical practice, were less comfortable addressing this issue, tended to listen less carefully and try to change the subject more than other groups. Residents with high spirituality and low religiousness (S/r) inquired more about religious/spiritual issues, while those with high religiousness/spirituality (S/R) were more supportive and reported fewer barriers to addressing these issues. Concerning ethical issues (e.g., physician-assisted suicide, withdrawal of life support, abortion), S/R had more objections than others.
RESUMEN
BACKGROUND: This study assessed the effects of a Japanese leaflet-based health guide for older Japanese-Brazilian adults living in Brazil, on health literacy, self-efficacy, and satisfaction with the health guide and participants' subjective health status. METHODS: The study followed a one-group pretest-posttest design and was set in the Japanese-Brazilian community in South Brazil. The 21 participants were Japanese-Brazilian individuals aged over 65 years, living in Brazil, and able to converse in Japanese. During the annual health checkup of 2016, we provided about 20 min of health guidance in Japanese using our leaflet, which included information about lifestyle-related diseases, recommended salt and sugar intake levels, and graphical charts. Participants' health literacy (HL) was the primary outcome; self-efficacy and satisfaction with the leaflet-based health guide and participants' subjective health status were secondary outcomes. We assessed the effect after completion of the health checkups in 2016 and 2017. Data were analyzed using repeated measures of ANOVA and the Bonferroni multiple comparison test as required. RESULTS: There were no statistical significant differences in HL (functional HL: p-value = 0.22; communicative HL: p-value = 0.17; critical HL: p-value = 0.40; total HL score: p-value = 0.12) and self-efficacy (p-value = 0.28) across the three assessment points. We detected a statistical significant difference in satisfaction with the health guide, post-intervention in 2016 and 2017 (baseline score: 86.7±20.4; post-intervention score in 2016: 92.5±12.2; post-intervention score in 2017: 76.2±21.9; p-value of repeated ANOVA < 0.01, ηp2 = 0.28; p-value of the multiple comparison in 2016 and 2017 = 0.01, 95% CI 4.09-28.51). However, the Bonferroni multiple comparison test did not show pairwise difference during multiple comparisons of participants' satisfaction with their subjective health status (scores: baseline, 69.6±24.2; post-intervention in 2016, 78.5±21.1; post-intervention in 2017, 58.0±31.1; p-value of repeated ANOVA = 0.02, ηp2 = 0.21; p-values of the multiple comparisons> 0.05). Scores of all outcomes, except self-efficacy, increased from baseline to post-intervention in 2016, but declined at post-intervention in 2017. CONCLUSIONS: The leaflet-based intervention appeared to have short-term effects. The findings suggest that direct intervention in older adults' native language may improve their satisfaction when living in non-native countries.

OBJECTIVE: This study aimed to investigate the correlation between apolipoprotein E (APOE) ε4 and the mini-mental state examination (MMSE) dimension in an elderly population, using baseline data from the Bambui (Brazil) Cohort Study of Aging. DESIGN: We conducted a community-based cross-sectional study. SETTING: The study took place at Bambui city, Minas Gerais State, Southeast Brazil. PARTICIPANTS: A total of 1408 (87.7%) cohort participants had complete information on the MMSE and health measures. MEASUREMENTS: The association between each of five dimensions (concentration, language/praxis, orientation, attention, and memory) underlying the MMSE and APOE ε4 allele was assessed using multivariate linear regression models. Potential confounding variables included sociodemographic factors and selected biomarkers. RESULTS: The main finding is a strong negative association between the presence of APOE ε4 allele and memory dimension in the MMSE (fully adjusted ß coefficient = -0.14; 95% confidence interval: -0.27 to -0.04; p = 0.016). No other cognitive dimensions showed significant associations with the APOE ε4 allele. CONCLUSION: This study is the first to investigate the association between dimensions of the MMSE, obtained from principal component analysis and APOE ε4 carrier status in community-dwelling older adults taking into account a range of potential confounding factors. We found a strong negative association between the presence of APOE ε4 allele and scores on memory dimension of the MMSE, but no effect on other dimensions. Our results reinforce previous data on the literature that APOE ε4 allele has a significant effect on cognitive performance that can be detected even in screening tests, such as the MMSE.

Elevated serum levels of C-reactive protein (CRP) have been associated with leukoaraiosis in elderly brain. However, several studies indicate that leukoaraiosis is associated with an increased risk of cognitive impairment. It is unknown how the effect of CRP on cognition is mediated by leukoaraiosis. The purpose of this study is to assess the relationship between serum levels of CRP, the presence of leukoaraiosis, and cognitive impairment in a population of coronary patients over 50 years old. CRP levels explained 7.18% (P: 0.002) of the variance of the MMSE. The adjustment for the presence of leukoaraiosis little changed this variance (5.98%, P: 0.005), indicating that only a small portion of the CRP influence on cognition was mediated via leukoaraiosis. Patients with CRP levels ≥ 5.0 had 2.9 (95% CI: 1.26-6.44) times more chance to present cognitive impairment (P: 0.012). We found that elevated serum levels of CRP were associated with increased risk of cognitive impairment in elderly and it was not mediated by presence of leukoaraiosis.

Given the aging global population, identifying heart failure (HF) phenotypes has become crucial, as distinct disease characteristics can influence treatment and prognosis in older adults. This study aimed to analyze the association between clustering of cardiovascular risk factors and HF in older adults. A cross-sectional epidemiological study was conducted with 1322 older adults (55% women, mean age 70.4) seen in primary health care. Diagnosis of HF was performed by a cardiologist based on diagnostic tests and medical history. Cardiovascular risk factors included hypertension, diabetes, hypercholesterolemia, and smoking. Using logistic regression, potential associations were tested. Individual risk factor analysis showed that older adults with hypertension, diabetes, or hypercholesterolemia had up to 7.6 times higher odds to have HF. The cluster where older adults had only one risk factor instead of none increased the odds of HF by 53.0%. Additionally, the odds of older patients having HF ranged from 3.59 times for the two-risk factor cluster to 20.61 times for the simultaneous presence of all four factors. The analysis of clusters substantially increasing HF risk in older adults revealed the importance of individualizing subgroups with distinct HF pathophysiologies. The clinical significance of these clusters can be beneficial in guiding a more personalized therapeutic approach.
RESUMEN
BACKGROUND: Adhering to a diet adequate in macronutrients is crucial for the secondary prevention of cardiovascular diseases. OBJECTIVE: To assess the prevalence of adherence to recommendations for the consumption of dietary fatty acids for the prevention and treatment of cardiovascular diseases and to estimate whether the presence of certain cardiovascular risk factors would be associated with adherence. METHODS: Cross-sectional study using baseline data from 2,358 participants included in the "Brazilian Cardioprotective Nutritional Program Trial". Dietary intake and cardiovascular risk factors were assessed. Adequate intake of polyunsaturated fatty acids (PUFA) was considered as ≥10% of total daily energy intake; for monounsaturated fatty acids (MUFA), 20%; and for saturated fatty acids (SFA), <7% according to the Brazilian Society of Cardiology. A significance level of 5% was considered in the statistical analysis. RESULTS: No participant adhered to all recommendations simultaneously, and more than half (1,482 [62.9%]) did not adhere to any recommendation. Adherence exclusively to the SFA recommendation was the most prevalent, fulfilled by 659 (28%) participants, followed by adherence exclusively to the PUFA (178 [7.6%]) and MUFA (5 [0.2%]) recommendations. There was no association between the number of comorbidities and adherence to nutritional recommendations (p = 0.269). Participants from the Brazilian Northeast region showed a higher proportion of adherence to SFA consumption recommendations (38.42%) and lower adherence to PUFA intake (3.52%) (p <0.001) compared to other regions. CONCLUSIONS: Among the evaluated sample, there was low adherence to nutritional recommendations for dietary fatty acid consumption.
FUNDAMENTO: A adesão à uma alimentação adequada em macronutrientes é fundamental para a prevenção secundária de doenças cardiovasculares. OBJETIVO: Avaliar a prevalência de adesão às recomendações de consumo de ácidos graxos para prevenção e tratamento de doenças cardiovasculares, e estimar se a presença de determinados fatores de risco cardiovascular estaria associada à adesão. MÉTODOS: Estudo transversal com os dados de linha de base de 2358 participantes do estudo "Brazilian Cardioprotective Nutritional Program Trial". Dados de consumo alimentar, e fatores de risco cardiovascular foram avaliados. Foi considerada, de acordo com a Sociedade Brasileira de Cardiologia, uma ingestão adequada de ácidos graxos poli-insaturados (AGPI) ≥10% do consumo total de energia diária, para ácidos graxos monoinsaturados (AGM), 20% e para ácidos graxos saturados (AGS), <7%. Na análise estatística foi considerando nível de significância de 5%. RESULTADOS: Nenhum participante aderiu a todas as recomendações de forma simultânea e mais da metade (1482 [62,9%]) não aderiu a nenhuma recomendação. A adesão exclusivamente à recomendação de AGS foi a mais prevalente, sendo cumprida por 659 (28%) dos participantes, seguida da adesão exclusivamente à recomendação de AGP (178 [7,6%]) e de AGM (5 [0,2%]). Não houve associação entre o número de comorbidades e a adesão às recomendações nutricionais (p =0,269). Os participantes da região Nordeste do país apresentaram maior proporção de adesão às recomendações para consumo de AGS (38,42%), e menor para ingestão de AGPI (3,52%) (p <0,001) em comparação às demais. CONCLUSÕES: Na amostra avaliada, evidenciou-se baixa adesão às recomendações nutricionais para consumo de ácidos graxos.

BACKGROUND: Identifying asymptomatic individuals at risk of developing cardiovascular disease is one of the main goals of preventive cardiology. The coronary calcium score (CCS) makes it possible to estimate vascular age, which has shown to be more reliable than chronological age for determining cardiovascular risk. OBJECTIVES: To reclassify cardiovascular risk based on arterial age and evaluate CCS progression during follow-up. METHODS: We included 150 asymptomatic men who underwent clinical and CCS evaluation in 2 evaluations with an interval of 7.6 years. We classified patients by traditional risk scores and arterial age. We evaluated which variables were associated with greater CCS progression during the period, considering a statistical significance level of 5% (p < 0.05). RESULTS: The use of arterial age in the stratification of cardiovascular risk in comparison with the Framingham risk score (FRS) reclassified 29% of individuals to a higher risk category and 37% to a lower risk category. Regarding the American Heart Association and American College of Cardiology score (ASCVD), 31% were reclassified as higher risk and 36% as lower risk. The initial classification by arterial age was directly related to the progression of CCS throughout follow-up (p < 0.001). This was not observed for the FRS (p = 0.862) or ASCVD (p = 0.153). The individual variables most associated with CCS progression were high systolic blood pressure and low HDL. CONCLUSION: Cardiovascular risk stratification using arterial age showed a better association than the FRS and ASCVD in identifying individuals with higher risk of atherosclerosis progression.
FUNDAMENTO: Identificar os indivíduos assintomáticos sob risco de desenvolver doenças cardiovasculares é um dos principais objetivos da cardiologia preventiva. O escore de cálcio coronariano (ECC) permite estimar a idade vascular, que se mostrou mais fidedigna que a idade cronológica na determinação do risco cardiovascular. OBJETIVOS: Reclassificar o risco cardiovascular com base na idade arterial e avaliar a progressão do escore de cálcio durante o seguimento. MÉTODOS: 150 homens assintomáticos foram submetidos a avaliação clínica e do ECC em 2 avaliações com intervalo de 7,6 anos. Classificamos os pacientes pelos escores de risco tradicionais e pela idade arterial. Avaliamos quais variáveis se associaram a maior progressão do ECC durante o período. O nível de significância estatística considerado foi de 5% (p < 0,05). RESULTADOS: A utilização da idade arterial na estratificação do risco cardiovascular em comparação ao escore de risco de Framingham (ERF) reclassificou 29% dos indivíduos para uma categoria de risco superior e 37% para uma categoria inferior. Em relação ao escore da AHA e ACC (ASCVD), 31% passaram para um risco maior e 36% para um risco menor. A classificação inicial pela idade arterial teve relação direta com a progressão do ECC ao longo do seguimento (p < 0,001), fato que não foi observado para o ERF (p = 0,862) e ASCVD (p = 0,153). As variáveis individuais que mais se associaram à progressão do ECC foram a pressão arterial sistólica e o HDL baixo. CONCLUSÃO: A estratificação de risco cardiovascular utilizando a idade arterial apresentou melhor associação que o ERF e ASCVD na identificação de indivíduos com maior risco de progressão da aterosclerose.

BACKGROUND: Bed rest during hospitalization can negatively impact functional independence and clinical status of older individuals. Strategies focused on maintaining and improving muscle function may help reverse these losses. This study investigated the effects of a short-term multicomponent exercise intervention on maximal strength and muscle power in hospitalized older patients. METHODS: This secondary analysis of a randomized clinical trial was conducted in an acute care unit in a tertiary public hospital. Ninety (39 women) older patients (mean age 87.7 ± 4.8 years) undergoing acute-care hospitalization [median (IQR) duration 8 (1.75) and 8 (3) days for intervention and control groups, respectively]) were randomly assigned to an exercise intervention group (n = 44) or a control group (n = 46). The control group received standard care hospital including physical rehabilitation as needed. The multicomponent exercise intervention was performed for 3 consecutive days during the hospitalization, consisting of individualized power training, balance, and walking exercises. Outcomes assessed at baseline and discharge were maximal strength through 1 repetition maximum test (1RM) in the leg press and bench press exercises, and muscle power output at different loads (≤30% of 1RM and between 45% and 55% of 1RM) in the leg press exercise. Mean peak power during 10 repetitions was assessed at loads between 45% and 55% of 1RM. RESULTS: At discharge, intervention group increased 19.2 kg (Mean Δ% = 40.4%) in leg press 1RM [95% confidence interval (CI): 12.1, 26.2 kg; P < 0.001] and 2.9 kg (Mean Δ% = 19.7%) in bench press 1RM (95% CI: 0.6, 5.2 kg; P < 0.001). The intervention group also increased peak power by 18.8 W (Mean Δ% = 69.2%) (95% CI: 8.4, 29.1 W; P < 0.001) and mean propulsive power by 9.3 (Mean Δ% = 26.8%) W (95% CI: 2.5, 16.1 W; P = 0.002) at loads ≤30% of 1RM. The intervention group also increased peak power by 39.1 W (Mean Δ% = 60.0%) (95% CI: 19.2, 59.0 W; P < 0.001) and mean propulsive power by 22.9 W (Mean Δ% = 64.1%) (95% CI: 11.7, 34.1 W; P < 0.001) at loads between 45% and 55% of 1RM. Mean peak power during the 10 repetitions improved by 20.8 W (Mean Δ% = 36.4%) (95% CI: 3.0, 38.6 W; P = 0.011). No significant changes were observed in the control group for any endpoint. CONCLUSIONS: An individualized multicomponent exercise program including progressive power training performed over 3 days markedly improved muscle strength and power in acutely hospitalized older patients.

INTRODUCTION: Coffee is one of the most consumed foodstuffs worldwide. Studies of coffee intake in healthy subjects have shown controversial effects on vascular function. However, little is known of coffee intake effects on the endothelium of overweight and obese individuals. OBJECTIVE: To investigate the acute effects of caffeinated and decaffeinated coffee intake on the endothelial function and arterial stiffness in overweight and obese individuals. METHODS: A randomized, double-blind, crossover clinical trial was designed to investigate the effects of regular caffeinated coffee and decaffeinated coffee on the endothelium. Each subject had both caffeinated coffee and decaffeinated coffee, separated by a washout period of seven days. The endothelial function was measured by flow-mediated dilation (FMD) assessed by ultrasound. Arterial stiffness was measured by an automatic oscillometric device. Blood samples were collected to assess the lipid and nitric oxide profiles. RESULTS: There were 18 subjects included in the study, aged 37.4 ± 10.0 years, with an average BMI of 28.96 ± 2.42, with the majority being female (61.1%). The caffeinated coffee increased central systolic blood pressure (P < 0.001), central diastolic blood pressure (P < 0.001) and pulse wave velocity (P < 0.001), but the decaffeinated coffee did not affect these variables. However, there was a better effect on FMD in the caffeinated coffee intake group (P = 0.014). CONCLUSION: In overweight and obese individuals, caffeinated coffee increased central blood pressure and pulse wave velocity but not the decaffeinated coffee. While caffeinated coffee showed an improvement on hyperemia-induced endothelial function.

INTRODUCTION: Parkinsonism is one of the most common neurological disorders affecting the elderly. Several population-based studies have determined the epidemiology of parkinsonism, mainly Parkinson's disease (PD), but there is still little evidence in the Brazilian population. This protocol study aims to assess the prevalence and incidence of cases of PD and other parkinsonian syndromes in a 5-year cohort in a population-based study in the southern region of Brazil. METHODS AND ANALYSIS: A prospective population-based longitudinal study, with a cohort of development of cases of parkinsonism, divided into two phases: in phase I, two questionnaires to screen for parkinsonism (Tanner's questionnaire), Rapid Eyes Movement (REM) sleep behaviour disorder (REM Sleep Behavior Disorder Single-Question Screen) and a short interview will be conducted with all elderly residents of Veranópolis (the first longevity Brazilian county located in the Rio Grande do Sul, Brazil) aged 60 or over. The positive screened cases will be examined independently by at least two movement disorder-trained physicians and prevalence will be determined. A comprehensive evaluation of prodromic symptoms, risk factors and clinical characteristics will be carried out. Subjects with subtle parkinsonism and a sample of healthy subjects will be followed for 5 years in a developmental cohort of parkinsonism cases. For crude incidence, all individuals admitted at the beginning of the study will be re-evaluated. ETHICS AND DISSEMINATION: The study was approved by the research ethics committee of the Hospital de Clínicas de Porto Alegre (protocol n° 4.095.609). All participants provide their informed consent before evaluations. Findings from this survey will be disseminated through peer-reviewed publications and will be presented at conferences.

BACKGROUND: Knowledge of environmental and genetic factors for healthy aging in elderly people is controversial. In addition to this evidence, few studies have been designed for this population. OBJECTIVES: To investigate the relationship between the most frequent apolipoprotein E (APOE) genotypes and mortality in very elderly individuals living in a community and to evaluate survival according to cardiovascular risk factors. METHODS: A sample of 74 elderly individuals aged ≥ 80 years, from the Veranópolis Project cohort, was selected for APOE genotyping. At baseline, anthropometric variables, glucose and lipid levels, blood pressure, and lifestyle variables (smoking, alcohol consumption, and physical activity) were collected. The Bayer Activities of Daily Living Scale was applied to their caregivers. Total study follow-up was 21 years. Two-sided p < 0.05 was considered statistically significant. RESULTS: There was no association between APOE genotypes and mortality. However, the risk of death in elderly smokers was 2.30 times higher (hazard ratio [HR], 95% CI 1.01 to 5.24); in individuals with diabetes, it was 3.95 times higher (HR, 95% CI 1.27 to 12.30) than in individuals without diabetes. Subjects who practiced vigorous physical activity had a 51% reduction in risk of death (HR = 0.49, 95% CI 0.27 to 0.88). For an increase of 1 mmHg in systolic blood pressure, there was a 2% reduction (HR = 0.98, 95% CI 0.97 to 0.99) in risk of death. CONCLUSION: In this sample population, APOE genotypes were not associated with mortality. However, classic cardiovascular risk factors may be important for overall mortality in the very elderly.
FUNDAMENTO: O conhecimento dos fatores ambientais e genéticos para um envelhecimento bem-sucedido em idosos longevos é controverso. Acrescenta-se a esta evidência, o fato de serem poucos os estudos delineados com essa população. OBJETIVO: Investigar a relação entre os genótipos mais frequentes da apolipoproteína E (APOE) e a mortalidade em idosos longevos que vivem em comunidade e sua sobrevida de acordo com os fatores de risco cardiovascular. MÉTODOS: Uma amostra de 74 idosos com 80 anos ou mais da coorte do Projeto Veranópolis foi selecionada para genotipagem da APOE. Na linha de base, foram coletadas variáveis antropométricas, dosagens sanguíneas de glicose e lipídeos, pressão arterial e variáveis de estilo de vida (tabagismo, consumo de álcool e atividade física). A escala Bayer de Atividades da Vida Diária foi aplicada aos cuidadores dos idosos. O tempo de seguimento total do estudo foi 21 anos. Um p<0,05 bicaudal foi considerado estatisticamente significativo. RESULTADOS: Não encontramos associação entre os genótipos da APOE e mortalidade. Entretanto, o risco de morte em idosos fumantes foi 2,30 vezes (hazard ratio [HR]; intervalo de confiança de 95% [IC 95%] 1,01 a 5,24); em diabéticos, 3,95 vezes (HR; IC 95% 1,27 a 12,30) do risco dos não diabéticos. Indivíduos que praticavam atividade física vigorosa tiveram uma redução no risco de óbito em 51% (HR = 0,49; IC 95% 0,27 a 0,88). Para o aumento de 1 mmHg na pressão arterial sistólica houve uma redução de 2% (HR = 0,98; IC 95% 0,97 a 0,99) no risco de morte. CONCLUSÃO: Nesta amostra de longevos, não houve associação entre os genótipos da APOE e mortalidade. Entretanto, os fatores de risco cardiovasculares clássicos podem ser importantes para a mortalidade geral em pessoas muito idosas.

Coronary artery disease (CAD) is one of the leading causes of mortality. High circulating levels of low-density lipoprotein (LDL) in the blood are associated with cardiovascular mortality, whether through an etiological role or through its association with the progression of CAD per se. Randomized clinical trials have shown that, when LDL levels are reduced, cardiovascular risk is also reduced, which reinforces this association. The first major trial involving a hypolipidemic agent of the statin family, the Scandinavian Simvastatin Survival Study (4S), was published in 1994 and found a significant reduction in mortality in patients at high cardiovascular risk. However, even in subsequent studies with different statins, a residual risk persisted, and this seems not to have changed over time; it is speculated that this risk may be due to statin intolerance. In this scenario, the potential exists for novel hypolipidemic agents to drive a true revolution in the therapy of dyslipidemia. The recent discovery of PCSK9 inhibitors (PCSK9i), a class of hypolipidemic monoclonal antibodies, is extremely promising. PCSK9 inhibition is capable of promoting a mean LDL reduction of up to 60%, with potential for very significant clinical repercussions, as every 38 mg/dL reduction in LDL appears to be associated with a 22% reduction in cardiovascular risk. This review addresses a brief history of PCSK9i, major trials of these drugs, cardiovascular outcomes, and aspects related to their efficacy and safety. Finally, the molecular mechanisms and possible pleiotropic effects of PCSK9i are also discussed.

INTRODUCTION: Sarcopenia is a prevalent condition in the elderly population, imposing a significant impact over their functional ability as well as their quality of life. Furthermore, it is associated with greater incidence of major geriatric outcomes, as reduced mobility, falls, loss of independence, cognitive impairment, and all-cause mortality. Physical Exercise Programs directed to improve muscle mass and its function may be key to reduce sarcopenia consequences. However, a significant heterogeneity is found in clinical trials, especially as a consequence of different exercise protocols applied to research subjects. OBJECTIVES: To access the effects of physical exercise programs compared to no exercise interventions to improve sarcopenia components and its determinants in sarcopenic elder individuals. METHODS: A systematic review was conducted in the Pubmed database to identify randomized clinical trials (RCTs) which tested the effects of physical exercise programs to manage sarcopenia components in sarcopenic elder individuals. Two independent reviewers assessed the studies' eligibility according to specified inclusion criteria in a four-step strategy. Data regarding population characteristics, muscle mass, muscle quality, muscle strength, and muscle function were extracted from each one of the included studies. Assessment of quality and individual studies risk of bias were assessed through Cochrane Risk of Bias Tool®. Assuming theoretical expected heterogeneity among studies, especially regarding different physical exercise programs and different outcome measurements, authors decided to be conservative and present study results in descriptive tables. RESULTS: Search strategy retrieved 298 papers on PubMed database. Three more were identified through manual search, being 301 studies revised for inclusion. 278 were excluded during title/abstract review. After further evaluation of 23 full-texts, 5 RCTs were included. All 5 trials tested the efficacy of isolated exercise programs to improve sarcopenia components in the elderly compared to no physical intervention. Resistance training was the main intervention component in all included trials compared to inactive control groups (health education mainly). Physical training improved muscle strength, muscle quality, and muscle function compared to inactive control groups. Considering muscle mass, no differences were demonstrated. Data meta-analysis was not possible to be performed due to high heterogeneity among trials and small number of studies for each outcome comparison. CONCLUSION: Heterogeneity among trials and small number of RCTs limited robust conclusions and data meta-analysis. However, resistance training protocols can improve muscle strength and physical performance in elders previously diagnosed with sarcopenia, although its effect size and clinical impact are barely relevant.
RESUMEN
Resumo Objetivo Estimar a prevalência de insuficiência cardíaca (IC) e explorar sua possível associação com o consumo de alimentos ultraprocessados (AUP) em idosos. Método Este estudo transversal utilizou prontuários médicos de 1.322 idosos (55% mulheres; idade média de 70,4 anos) tratados na atenção primária à saúde no estado de Roraima, Brasil. Um cardiologista diagnosticou a IC com base em testes diagnósticos como ecocardiografia, avaliação clínica e análise do histórico médico. Nutricionistas avaliaram o consumo de AUP utilizando um formulário nacional comumente utilizado nas unidades de saúde primária brasileiras. Resultados Os achados revelaram que 15,4% dos idosos tinham IC. Observaram-se associações significativas entre grupos de AUP e IC, com a probabilidade de IC variando de OR=1,97 (IC 95% =1,36-2,84) para o consumo de hambúrgueres e/ou salsichas a OR=2,59 (IC 95% =1,73-3,74) para o consumo de biscoitos, doces e guloseimas. Conclusão O consumo de AUP foi associado a uma alta prevalência de IC nessa amostra de idosos brasileiros. Formuladores de políticas e profissionais de saúde diretamente envolvidos com essa população devem colaborar em ações direcionadas e orientações para reduzir o consumo de AUP e aumentar a ingestão de alimentos não processados.
Abstract Objective To estimate the prevalence of heart failure (HF) and explore its potential association with the consumption of ultra-processed foods (UPF) in older adults. Method This cross-sectional study utilized medical records of 1,322 older adults (55% women; mean age of 70.4 years) treated in primary health care facilities in the state of Roraima, Brazil. A cardiologist diagnosed HF based on diagnostic tests such as echocardiography, clinical evaluation, and analysis of medical history. Nutritionists assessed UPF consumption using a nationally standardized form commonly employed in Brazilian primary health care units. Results The findings revealed that 15.4% of older adults had HF. Significant associations were observed between UPF groups and HF, with the probability of HF ranging from OR=1.97 (95% CI=1.36-2.84) for the consumption of hamburgers and/or sausages to OR=2.59 (95% CI=1.73-3.74) for the consumption of filled biscuits, sweets, and treats. Conclusion The consumption of UPF was associated with a high prevalence of HF in this sample of Brazilian older adults. Policymakers and healthcare professionals directly involved with this population should collaborate on targeted interventions and guidelines to reduce UPF consumption and increase the intake of unprocessed foods.
RESUMEN
FUNDAMENTO: A adesão à uma alimentação adequada em macronutrientes é fundamental para a prevenção secundária de doenças cardiovasculares. OBJETIVO: Avaliar a prevalência de adesão às recomendações de consumo de ácidos graxos para prevenção e tratamento de doenças cardiovasculares, e estimar se a presença de determinados fatores de risco cardiovascular estaria associada à adesão. MÉTODOS: Estudo transversal com os dados de linha de base de 2358 participantes do estudo "Brazilian Cardioprotective Nutritional Program Trial". Dados de consumo alimentar, e fatores de risco cardiovascular foram avaliados. Foi considerada, de acordo com a Sociedade Brasileira de Cardiologia, uma ingestão adequada de ácidos graxos poli-insaturados (AGPI) ≥10% do consumo total de energia diária, para ácidos graxos monoinsaturados (AGM), 20% e para ácidos graxos saturados (AGS), <7%. Na análise estatística foi considerando nível de significância de 5%. RESULTADOS: Nenhum participante aderiu a todas as recomendações de forma simultânea e mais da metade (1482 [62,9%]) não aderiu a nenhuma recomendação. A adesão exclusivamente à recomendação de AGS foi a mais prevalente, sendo cumprida por 659 (28%) dos participantes, seguida da adesão exclusivamente à recomendação de AGP (178 [7,6%]) e de AGM (5 [0,2%]). Não houve associação entre o número de comorbidades e a adesão às recomendações nutricionais (p =0,269). Os participantes da região Nordeste do país apresentaram maior proporção de adesão às recomendações para consumo de AGS (38,42%), e menor para ingestão de AGPI (3,52%) (p <0,001) em comparação às demais. CONCLUSÕES: Na amostra avaliada, evidenciou-se baixa adesão às recomendações nutricionais para consumo de ácidos graxos.
RESUMEN
Resumo Fundamento Identificar os indivíduos assintomáticos sob risco de desenvolver doenças cardiovasculares é um dos principais objetivos da cardiologia preventiva. O escore de cálcio coronariano (ECC) permite estimar a idade vascular, que se mostrou mais fidedigna que a idade cronológica na determinação do risco cardiovascular. Objetivos Reclassificar o risco cardiovascular com base na idade arterial e avaliar a progressão do escore de cálcio durante o seguimento. Métodos 150 homens assintomáticos foram submetidos a avaliação clínica e do ECC em 2 avaliações com intervalo de 7,6 anos. Classificamos os pacientes pelos escores de risco tradicionais e pela idade arterial. Avaliamos quais variáveis se associaram a maior progressão do ECC durante o período. O nível de significância estatística considerado foi de 5% (p < 0,05). Resultados A utilização da idade arterial na estratificação do risco cardiovascular em comparação ao escore de risco de Framingham (ERF) reclassificou 29% dos indivíduos para uma categoria de risco superior e 37% para uma categoria inferior. Em relação ao escore da AHA e ACC (ASCVD), 31% passaram para um risco maior e 36% para um risco menor. A classificação inicial pela idade arterial teve relação direta com a progressão do ECC ao longo do seguimento (p < 0,001), fato que não foi observado para o ERF (p = 0,862) e ASCVD (p = 0,153). As variáveis individuais que mais se associaram à progressão do ECC foram a pressão arterial sistólica e o HDL baixo. Conclusão A estratificação de risco cardiovascular utilizando a idade arterial apresentou melhor associação que o ERF e ASCVD na identificação de indivíduos com maior risco de progressão da aterosclerose.
Abstract Background Identifying asymptomatic individuals at risk of developing cardiovascular disease is one of the main goals of preventive cardiology. The coronary calcium score (CCS) makes it possible to estimate vascular age, which has shown to be more reliable than chronological age for determining cardiovascular risk. Objectives To reclassify cardiovascular risk based on arterial age and evaluate CCS progression during follow-up. Methods We included 150 asymptomatic men who underwent clinical and CCS evaluation in 2 evaluations with an interval of 7.6 years. We classified patients by traditional risk scores and arterial age. We evaluated which variables were associated with greater CCS progression during the period, considering a statistical significance level of 5% (p < 0.05). Results The use of arterial age in the stratification of cardiovascular risk in comparison with the Framingham risk score (FRS) reclassified 29% of individuals to a higher risk category and 37% to a lower risk category. Regarding the American Heart Association and American College of Cardiology score (ASCVD), 31% were reclassified as higher risk and 36% as lower risk. The initial classification by arterial age was directly related to the progression of CCS throughout follow-up (p < 0.001). This was not observed for the FRS (p = 0.862) or ASCVD (p = 0.153). The individual variables most associated with CCS progression were high systolic blood pressure and low HDL. Conclusion Cardiovascular risk stratification using arterial age showed a better association than the FRS and ASCVD in identifying individuals with higher risk of atherosclerosis progression.
RESUMEN
OBJECTIVE: To evaluate the capacity of total anterior thigh thickness, quadriceps muscle thickness, and quadriceps contractile index, all measured by bedside ultrasound, to predict rehospitalization, functional decline, and death in elderly patients 3 months after hospital discharge. To evaluate intra and interobserver reproducibility of the dominant thigh evaluation method by point of care ultrasound. METHODS: Cohort study of patients aged 65 years or more admitted to a medium complexity unit in a teaching hospital in southern Brazil. Comprehensive geriatric assessment and ultrasound evaluation of the dominant thigh of each participant were performed. After 3 months of hospital discharge, telephone contact was made to evaluate the outcomes of rehospitalization or death and functional decline-assessed by the 100 points Barthel scale and defined as a decrease of five or more points. RESULTS: 100 participants were included. There was no statistically significant difference between intraobserver measurements in the GEE method analysis (p > 0.05), and the mean bias obtained in Bland-Altman plots was close to zero in all four analyses performed, suggesting good intra and interobserver agreement. There was a significant correlation between the echographic measurements (quadriceps thickness and contractile index) and gait speed, timed up and go, and handgrip tests. There was a significant association between contractile index (quadriceps thickness over total anterior thigh thickness multiplied by 100) lower than 60% and functional decline (relative risk 1.35; CI 95% 1.10-1.65; p = 0.003) as well as between the thickness of the quadriceps and rehospitalization or death, in both individuals with preserved walking capacity and in bedridden elders (relative risk 1.34; CI 95% 1.02-1.75; p = 0.04). CONCLUSION: The ultrasonographic method to evaluate thigh thickness was easily applicable and reproducible. The thickness of the quadriceps could predict rehospitalization or death, even in those patients without walking capacity-unable to perform gait speed and timed up and go tests. Additionally, the contractile index was associated with functional decline after 3 months of hospital discharge. This is a promising result, which highlights the bedside ultrasound of the quadriceps as a potential tool for the prognosis evaluation of bedridden hospitalized elderly patients.
RESUMEN
Resumo: Introdução: Os universitários apresentam maior risco de adotar o comportamento sedentário em virtude da própria rotina, a qual requer muito tempo dedicado às aulas e a utilização frequente do computador para os estudos. Essa situação tem se tornado preocupante porque o comportamento sedentário tem sido associado a desfechos adversos em saúde, como mortalidade e doenças crônicas não transmissíveis. Objetivo: Este estudo teve como objetivo analisar o tempo despendido com o uso do computador como discriminador da obesidade, do sedentarismo e de fatores de risco cardiovascular em universitários. Método: Trata-se de estudo transversal realizado com 2.275 acadêmicos de cursos da área da saúde de uma fundação pública do estado de Goiás. Os dados foram obtidos por meio da aplicação de um questionário composto por variáveis sociodemográficas, relativas ao curso e a aspectos comportamentais e de saúde. A variável de desfecho foi o tempo utilizando o computador (TC). Identificaram-se o poder discriminatório e os pontos de corte do TC para os desfechos de interesse por meio das curvas Receiver Operating Characteristic (ROC) com IC95%. Resultado: O tempo médio usando o computador para estudos, trabalho ou lazer foi de 3,90 horas/dia para mulheres e 3,82 horas/dia para homens. A área sob a curva ROC entre o TC e o sedentarismo foi de 0,54 (IC95% 0,51-0,58) para mulheres e 0,56 (IC95% 0,50-0,63) para homens. Já para a hipertensão arterial sistêmica (HAS), foi de 0,57 (IC95% 0,50-0,64) para mulheres. Os melhores pontos de corte relacionados a essas condições foram 3,5 e 4,5 horas, respectivamente. Conclusão: O TC apresentou boa capacidade preditiva para discriminar o sedentarismo e a HAS entre universitários. Sugere-se que a diminuição do TC e sua substituição por atividades ativas possam contribuir para a melhoria do perfil de saúde e a qualidade de vida dos acadêmicos.
Abstract: Introduction: University students are at greater risk of adopting a sedentary behavior due to their routine, with a large amount of time being dedicated to classes and studying in front of a computer. This situation has become a matter of concern, because sedentary behavior has been associated with adverse health outcomes such as mortality and chronic non-communicable diseases. Objective: To analyze the time spent using the computer as a discriminator of obesity, sedentary lifestyle and cardiovascular risk factors in University students. Method: This was a cross-sectional study with 2,275 students from courses in the health area of a public institution in Goiás. Data were obtained by applying a questionnaire consisting of sociodemographic, course-related, behavioral and health variables. The outcome variable was time using the computer (TC). The discriminatory power and the cutoff points of time using the computer for the outcomes of interest were identified using the Receiver Operating Characteristic (ROC) curves with 95%CI. Result: The mean time spent using the computer for studying, working, or leisure was 3.90 hours/day for women and 3.82 hours/day for men. The area under the ROC curve between TC and sedentary lifestyle was 0.54 (95%CI 0.51-0.58) for women and 0.56 (95%CI 0.50 - 0.63) for men. As for systemic arterial hypertension (SAH) it was 0.57 (95%CI 0.50 - 0.64) for women. The best cutoff points related to these conditions were 3.5 and 4.5 hours, respectively. Conclusion: The TC showed good predictive capacity to discriminate a sedentary lifestyle and SAH among University students. It is suggested that the reduction of TC and its replacement by active activities can contribute to improving the health profile and quality of life of students.
RESUMEN
INTRODUCTION: Active aging is the process of optimizing opportunities for health, participation and security, aiming to improve quality of life as people age. A series of studies had demonstrated that a lower prevalence of depression is found among more active elderly. OBJECTIVE: To evaluate the association between indicators of active aging and depressive symptoms among the elderly (aged 60 years or more). METHOD: A population-based cross-sectional study was conducted with 1,006 elderly people (aged 60 years or over) from a small-sized Brazilian municipality. Depressive symptoms were assessed using the Geriatric Depression Scale - 15, with cutoff point ≥ 6 symptoms. Active aging was evaluated using indicators such as: active occupational situation, manual work, reading and physical activities. Data analyses used modified Poisson regression to obtain crude and adjusted prevalence ratios (PR). RESULTS: Most of the elderly people were: white, women and aged between 60 and 74 years. All the indicators of active aging were associated with the outcome. After controlling for socioeconomic, demographic and health variables, elderly people who worked, participated in groups, did manual work and maintained interests such as reading and talking to friends had lower prevalence of depressive symptoms compared to those not doing these activities. CONCLUSIONS: Active aging approaches may serve as a valuable mental health promotion strategy aimed at the elderly.
