Common mental disorders in patients undergoing lower limb amputation: a population-based sample.

BACKGROUND: Amputations result in a variety of limitations that have emotional consequences for patients. The aim of the present study was evaluate non-psychotic disorders and their associated factors in a sample of people with lower limb amputations. METHOD: A cross-sectional study was conducted that assessed the association of sociodemographic and clinical variables in relation to psychiatric disorders evaluated through the Self Reporting Questionnaire (SRQ-20) for patients undergoing lower limb amputation. The association between the outcome of the SRQ-20 and the other variables was assessed with the chi-square and Student's t test; to explore the magnitude of association adjusted for covariates, a logistic regression model was developed. RESULTS: One hundred-thirty eight (138) patients were interviewed, and a prevalence of 43% (60/138) was observed for patients with mental disorders assessed with the SRQ-20 questionnaire. We also observed that male patients (p = 0.017) and those who were married (p = 0.035) had a lower rate of psychological problems; those who were not considered independent (p = 0.036) and those with a greater number of morbid conditions (p = 0.036) showed a higher positivity in relation to psychological morbidity (p = 0.003). Logistic regression analysis showed that only the associated chronic diseases (p = 0.0328) and lack of independence (p = 0.0197) remained significant. CONCLUSIONS: Given the high prevalence of mental disorders related to the number of associated morbid conditions and to the situation of dependency among lower limb amputees, the psychological and social assessment of these people is recommended, in addition to encouraging their self-care and the return to their activities.

Fat and fiber consumption are associated with peripheral arterial disease in a cross-sectional study of a Japanese-Brazilian population.

BACKGROUND: The Western diet plays a role for the epidemics of obesity and related diseases. This study examined a possible association between peripheral arterial disease (PAD) and the dietary components of Japanese immigrants living in Brazil. METHODS AND RESULTS: In this cross-sectional study, 1,267 subjects (aged > or =30 years) with complete dietary, clinical and laboratory data were studied according to a standardized protocol. Ankle-to-brachial index was used to identify subjects with PAD. The overall prevalence of PAD was 14.6%. Subjects with PAD were older, had lower education and higher mean values of blood pressure, triglycerides, and fasting and 2-h plasma glucose levels compared with those without the disease. Among the subjects with PAD, the consumption of fiber from whole grains (3.0 vs 3.4 g, p=0.001) and linoleic acids (11.0 vs 11.7 g, p=0.017) were lower and intake of total (72.8 vs 69.1 g, p=0.016) and saturated fatty acids (17.4 vs 16.3 g, p=0.012) were higher than those without PAD. Results of multiple logistic regression analysis showed a significant association between PAD with high total fat intake, low intake of fiber from fruit and oleic acid, independently of other variables. CONCLUSIONS: Despite limitations in examining the cause - effect relationship, the data support the notion that diet could be important in reducing the occurrence of PAD.

Macrovascular disease in a Japanese-Brazilian population of high prevalence of metabolic syndrome: associations with classical and non-classical risk factors.

BACKGROUND: The Japanese-Brazilian Diabetes Study detected high prevalence of metabolic syndrome (MS) in a population of Japanese ancestry living in Brazil. We describe the prevalence of macrovascular disease (MVD) and its association with classical and non-classical cardiovascular risk factors in this population. METHODS: An overall of 1163 individuals were studied; diagnosis of MVD was based on a score obtained from medical history, ankle-brachial pressure index and electrocardiogram, defining three groups: no MVD, possible MVD and definite MVD. RESULTS: Prevalence of MVD was 14.3% (possible MVD: 11.2%; definite MVD: 3.1%). Individuals with MS had higher rates of MVD (16.9% versus 11.2%; p<0.05). Comparing to no MVD, age, 2 h plasma glucose, anti-LDL(+) and anti-LDL(-) levels, and urinary albumin-to-creatinine ratio were higher in both categories with MVD; waist-to-hip ratio, fasting plasma glucose, HbA1c, total-to-HDL cholesterol ratio and triglycerides were higher in that with definite MVD; systolic blood pressure and homocysteine were higher in that with possible MVD. Using logistic regression, systolic blood pressure, smoking habit and anti-LDL(+) were independently associated with MVD. CONCLUSION: MVD is highly prevalent in Japanese-Brazilians and its association with MS was confirmed. A novel marker of lipoprotein modifications--anti-LDL(+) antibody--could be useful in identifying individuals at higher risk.
