RESUMO

Background It has been reported that a high intake of dairy products might be associated with an increased risk of Parkinson's disease (PD) in foreign studies, but no such study has yet been conducted on prodromal Parkinson's disease (pPD) and the Chinese population. Objective To investigate the prospective relationship between the intake of dairy products and pPD among people aged 55 and above in four provinces of China. Methods The research data were obtained from the baseline 2018 and follow-up 2020 surveys of Community-based Cohort Study on Nervous System Disease. A total of 9984 residents were selected who participated in both waves of surveys and had complete data on demographics, dietary products intake, and risk factors for PD. We evaluated the risk level and the numbers of related risk/prodromal markers of pPD in the participants based on a criteria recommended by the International Parkinson and Movement Disorder Society (MDS). Food Frequency Questionnaire was used to obtain food consumption data in the past 12 months, and the intake of dairy products was calculated and divided into non-consumption and tertiles of consumption (T1, T2, and T3 from low to high). Multiple linear regression was used to analyze the association between baseline dairy intake and risk level of follow-up pPD. Poisson regression and multinomial logit regression models were used to analyze the relationship of baseline dairy products and the number of risk/prodromal markers of follow-up pPD in the population, and multiple logistic regression was used to analyze each risk/prodromal marker of follow-up pPD according to baseline levels of dairy products intake. Results The percentage of residents without dairy products consumption was 58.02% in 2018, and the dairy products intakes were relatively high among residents being female, aged 55 to 74 years, with an education level of middle school and above, with a per capita monthly household income ≥ 1000 yuan, living in urban areas, and without active employment (P<0.05). The median risk level of pPD was 0.74% in 2020, and the proportion of residents with 3 to 5 markers was 66.74%. The multiple linear regression analysis results suggested no association between baseline dairy intake and follow-up risk level of pPD. The Poisson regression model showed that the high dairy products intake group at baseline (T3, median=250.00 g·d−1) was found to be 1.159 (95%CI: 1.065~1.261, Ptrend<0.001) times more likely to have the risk/prodromal markers of pPD at follow-up than non-consumers. When the number of markers was grouped, no statistically significant association was found by multiple logistic regression analysis. Conclusion Although high dairy products intake levels might be associated with pPD risk/prodromal markers among people aged 55 and above in four provinces of China, no direct association is found between dairy products intake and pPD risk levels in this study.

RESUMO

Background Gastrointestinal microbiota plays an important role in the development of Parkinson's disease (PD), and dietary factors have a great impact on intestinal micro ecology. At present, few studies focus on red meat and PD, especially prodromal PD (pPD). Objective To understand the relationships of the intake of red meat and processed meat products with pPD and the number of risk/prodromal markers, and to explore the association of dietary factors with pPD. Methods Based on the data of Community-based Cohort Study on Nervous System Disease in 2018 and 2020, adults aged 55 years and older with complete demographic information, dietary survey information, and information on risk factors related to PD were selected from four provinces of China. After excluding those reporting abnormal total energy intake or those reporting alcohol drinking or abused drugs for a long period of time, and confirmed mental diseases with prescribed drugs, a total of 10003 subjects were included. Food frequency questionnaire was used to calculate the intake of red meat and processed meat products. The pPD-related risk/prodromal markers were selected following the International Parkinson and Movement Disorder Society criteria for pPD, and the risk level and the number of markers of pPD were then calculated. The relationship between the intake of red meat and processed meat and the risk level of pPD was analyzed by multiple linear regression. The relationship between the intake of red meat and processed meat and the pPD marker number groups was analyzed by multinomial logit regression model. Results In 2018, the intake of red meat and processed meat was 28.57 g·d−1 in the target population. In 2020, the median of the number of risk/prodromal markers was 3, and the median M (P25, P75) of the posterior probability of pPD was 0.74% (0.42%, 1.49%). The multiple linear regression analysis showed that the higher the intake of red meat and processed meat, the higher the risk level of pPD in follow-up (b=0.021, P<0.05). The multiple logit regression model showed that compared with the lowest quartile (Q1), the highest quartile (Q4) group of red meat and processed meat intake were more likely reporting 3−5 risk/prodromal markers than ≤ 2 risk/prodromal markers (OR=1.185, 95%CI: 1.015−1.382). Conclusion The intake level of red meat and processed meat is related to the risk level of pPD, and a higher intake of red meat and processed meat may be a potential risk factor of pPD.

RESUMO

Background China is witnessing an accelerated aging process and an increasingly serious situation of Parkinson's disease. Research on the pre-disease stage and its related influencing factors has gained more and more attention. Objective To analyze the current situation of prodromal Parkinson's disease (pPD) of people aged 55 years and above in four provinces of China, and to explore its influencing demographic and socio-economic characteristics. Methods Using the data of Community-based Cohort Study on Nervous System Disease in 2020, a total of 10724 participants with complete data on demographic and socio-economic factors and risk factors on Parkinson's disease were selected. Based on the criteria recommended by the International Parkinson and Movement Disorder Society (MDS), we evaluated risk level (i.e., post-test probability) of pPd, prevalence of possible or probable pPD, and number of pPD-related risk/prodromal markers in the participants. Multiple linear regression and multiple logistic regression models were used to analyze the influencing socio-demographic factors of risk level of pPd and prevalence of possible or probable pPD, and Poisson regression and multinomial logit regression models were used to analyze the influencing socio-demographic factors of the number of pPD-related risk/prodromal markers in the total sample, men, and women, respectively. Results The median (P25, P75) of post-test probability of pPD in 2020 was 0.78% (0.42%, 1.66%), the prevalence rate of possible or probable pPD was 0.34%, and 69.03% of the participants reported 3-5 pPD-related risk/prodromal markers. The post-test probabilities of men, those with older age, lower education level, per capita monthly household income < 1000 yuan, urban residency, or without active employment were higher (P<0.05). Men and being aged ≥ 75 years had a higher prevalence of possible or probable pPD (P<0.05). The OR of possible or probable pPD was 8.404 (95%CI: 2.839−24.879) in subjects aged ≥ 75 years versus those aged 55−64 years. Males, those without active employment, being less educated, with older age, and urban residents were more likely to report pPD-related risk/prodromal markers than those of the opposite groups (P<0.05). Conclusion Men, subjects aged ≥75 years, those with lower education level, urban residents, and those without active employment have higher risk levels of pPD and are more likely to report pPD-related risk/prodromal markers among people aged 55 years and above in the four provinces of China, poor economic situation is also associated with higher risk levels of pPD.

RESUMO

There are numerous particles, enzymes, and mechanisms in the lipid metabolism that are involved in the genesis of cardiovascular disease (CVD). Given its prevalence in populations and its impact on mortality, it is relevant to review the lipid metabolism as it may potentially provide subsidies to better prediction. This article reviews the importance of traditional cardiovascular risk factors and comments on the potential of novel lipid biomarkers involved in the physiopathology of CVD. The Framingham cohorts proved the role of traditional risk factors (physical inactivity, smoking, blood pressure, total cholesterol, LDL-C, HDL-C, plasma glucose) in the prediction of cardiovascular events. However, a significant number of individuals that suffer from a cardiovascular event has few or none of these factors. Such finding indicates the need for new biomarkers able to identify plaques that are more susceptible to rupture. Some of bloodstream biomarkers related to lipid metabolism are modified LDL particles, apolipoprotein AI (apo AI), apolipoprotein B, lipoprotein (a) [Lp (a)], cholesteryl ester transfer protein (CETP), subtypes of LDL and HDL particles, and lipoprotein-associated phospholipase A2 (Lp-PLA2). These factors participate in the atherosclerotic process, and are abnormal in individuals at high risk, or in those who suffered from a cardiovascular event. Lp (a) determination is already employed in clinical practice and should be included as a reference parameter for CVD monitoring. Furthermore, there are expectations for wider use of apo B, non-HDL cholesterol and total cholesterol / HDL-C determination to improve cardiovascular risk assessment.

RESUMO

OBJECTIVE: To estimate the prevalence of high blood pressure (BP) in school children, as well as the reported frequency of previous measurements of BP in these children, and to identify high BP risk markers in the sample. METHODS: This was a cross-sectional study involving 794 children aged 6 to 13 years, enrolled in public elementary schools. A questionnaire was given to parents/guardians, consisting of perinatal, socioeconomic data, and information on previous measurements of BP in these children. Anthropometric measurements included weight, height, waist, hip, and arm and neck circumference, in addition to the three BP measurements. Classification of BP levels was carried out according to current international recommendations, established in 2004. RESULTS: The prevalence of high BP (hypertension or prehypertension) was 7%. Only 21.7% of children had previously undergone BP measurements. The odds ratio of high BP among children with and without overweight was 2.9 (95% CI = 1.7 to 5.0, p < 0.001). None of the anthropometric measurements was superior to the Z-score of BMI as a predictor of high BP. History of hypertension during pregnancy (p < 0.001), prematurity (p = 0.006), maternal hypertension (p = 0.01), and paternal hypertension (p = 0.008) were also correlated with the presence of high BP in children. CONCLUSIONS: Overweight and family history constitute the main risk markers of high BP in children. The low frequency of BP measurement in children observed in this municipality contributes to the underdiagnosis of the disease, with irreversible consequences for these individuals. .


OBJETIVO: Estimar a prevalência de pressão arterial (PA) elevada em escolares, assim como a frequência relatada de aferição prévia da PA nessas crianças. Identificar marcadores de risco de PA elevada na amostra. MÉTODOS: Estudo transversal envolvendo 794 crianças de 6 a 13 anos, matriculadas no ensino público fundamental. Questionário entregue aos pais, com informações perinatais, sócio-econômicas e sobre aferição prévia da PA nas crianças. Avaliação antropométrica: peso, altura, circunferências abdominal, de quadril, braquial e cervical, além das três aferições da pressão arterial. Classificação dos níveis pressóricos conforme as recomendações internacionais atuais, estabelecidas em 2004. RESULTADOS: A prevalência de PA elevada (hipertensão ou pré-hipertensão) foi de 7%. Apenas 21,7% das crianças haviam sido previamente submetidas a aferições de PA. A razão de chances de PA elevada entre crianças com e sem excesso de peso foi de 2,9 (IC 95% = 1,7 a 5,0, p < 0,001). Nenhuma das medidas antropométricas foi superior ao Z de IMC como preditor de PA elevada. Histórico de hipertensão na gestação (p < 0,001), de prematuridade (p = 0,006), hipertensão materna (p = 0,01) e hipertensão paterna (p = 0,008) também se correlacionaram à presença de PA elevada nas crianças. CONCLUSÕES: Excesso de peso e história familiar configuram como principais marcadores de risco de PA elevada em crianças. A baixa frequencia de aferição da PA observada em crianças deste município contribui para o subdiagnóstico da doença, com consequências futuras irreversíveis para esses indivíduos. .

RESUMO

Homocysteine has emerged as a significant marker for occlusive vascular disease, but there has been some debate as to whether it is just an association (risk marker) or actually a causative factor (risk factor). To elucidate this, a retrospective statistical analysis was done of data generated in the course of our study on homocysteine and vascular disease. Homocysteine, lipid profile components and lipoprotein(a) were estimated in fasting blood samples drawn from 252 controls and 536 patients of occlusive vascular disease. The data were analyzed by SPSS version 17. Mean homocysteine levels were significantly higher (p<0.001) in all patients categories, as compared to controls. In fact, homocysteine level was the most significant biochemical risk factor for vascular disease. The odds ratios due to hyperhomocysteinemia varied from 3.170-4.153. When the cut-off was increased by 5 µmol/L, the odds ratio became almost three-fold. The prevalence of hyperhomocysteinemia increased by @20%, when the cut-off was reduced by 5 µmol/L. Statistical analysis of our data revealed that homocysteine conformed to Hill’s criteria of causation. Moreover, hyperhomocysteinemia was treatable by the administration of B-vitamins, even if the cause was genetic. Hence morbidity due to vascular disease could be reduced by identification and treatment of hyperhomocysteinemia.

Conclusiones: La presión del pulso puede ser instrumento muy útil en la observación, tratamiento y control de pacientes con riesgo de IMA, tanto e...


Introduction: The pulse pressure is an important marker and/or predictor of atherosclerotic cardiovascular accidents risks. Objective: To determine what relation there is between the pulse pressure and the myocardial acute infarction (MAI) in hypertensives and non-hypertensives, to establish observational criteria and the control of this component of blood pressure. Methods: A case-control, analytical and retrospective study was designed including a study group of 200 patients diagnosed with myocardial acute infarction, admitted in the Coronary Ward of the "Enrique Cabrera" Hospital during 2006-2007 and other control study in 200 patients admitted in Medicine Wards without cardiovascular disease excluding the diabetic a those aged under 30 according to a random selection. Study variables included: age, sex, smoking, systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), pulse pressure (PP) high blood pressure (HBP) and presence or not of myocardial infarction. Groups of pulse pressure = 50 mmHg and < 50 mmHg were created in hypertensive and non-hypertensive patients. Results: La myocardial infarction frequency in patients aged 30-39 was of 2 percent and in the group aged over 60 or more, it was of 68,5 percent; the 54 percent was of male sex, the HBP frequency was of 85,5 percent and that of smokers of 51,5 percent and with a PP = 50 mmHg, 76,0 percent. The relation among SAP, DAP, MAP and HBP with the increase of pulse pressure (p = 0,000). The association of pulse pressure with MAI in hypertensive patients was significant with a OR 6,46 CI 95 percent (3,72, 11,21) and in those non-hypertensive also it was significant with a OR 8,9 CI 95 percent (3,51, 22,56). Conclusions: The pulse pressure may be a very useful tool in the observation, treatment and control of patients with MAI risk, both, in hypertensives and non-hypertensives
