Type 2 diabetes mellitus (DM2) predisposes to an increased production of free radicals and a probable reduction in plasma antioxidants, including vitamin E. This cross-sectional study investigated the relationship between plasma α-tocopherol concentration and vitamin E intake in 58 Brazilians with DM2. Plasma α-tocopherol was determined by high-performance liquid chromatography. The intake of vitamin E-rich foods was assessed by a food frequency questionnaire. Total cholesterol and fractions were measured by colorimetric enzymatic methods. Data on demographic and socioeconomic factors, life habits, and anthropometry were obtained by a questionnaire and physical examination. The association between plasma α-tocopherol and vitamin E intake was assessed by multiple linear regression analysis. The following variables were included in the regression model: α-tocopherol, vitamin E intake, total cholesterol and fractions, body mass index, waist circumference, gender, age, education, occupation, income, smoking, alcohol intake, and blood pressure. There was no association between α-tocopherol and vitamin E intake, but there were significant associations between α-tocopherol and total cholesterol (p < 0.001) and waist circumference (p = 0.003). There were 36.2 % diabetics with low α-tocopherol concentrations (< 12 μmol/L) and 32.7 % with a low α-tocopherol/total cholesterol ratio (< 2.2). Further large, epidemiological, longitudinal studies, including measurements of gamma-tocopherol in blood, should be conducted to confirm our results. © 2011 by Hans Huber Publishers, Hogrefe AG, Bern.

Objective To evaluate the concentration of PTX3 in amniotic fluid (AF) during the final weeks of normal pregnancies and in pregnancies complicated by preterm delivery (PTD). Study design A cross-sectional study was conducted with 95 pregnant women followed to term and 25 who presented with PTD. Samples of AF from all patients were obtained during cesarean section and the PTX3 concentration was determined by enzyme immunoassay (ELISA). Maternal characteristics were compared by ANOVA and the Kruskal-Wallis and Chi square tests. Comparison between PTX3 concentrations in the "PTD in labor" and "PTD not in labor" groups were performed using the Mann-Whitney test. A p value <0.05 was considered statistically significant. Results Regarding term pregnancies, PTX3 concentrations were not statistically different across the period studied (37 weeks to 40 weeks). Among preterm pregnancies, those in preterm labor (PTL) presented higher PTX3 levels than those not in labor (p = 0.001) and the risk of occurrence of PTL increased by 1% with a rise of 1 pg/mL in PTX3. Conclusion PTX3 is a physiological constituent of the AF, and its concentration is elevated in the presence of spontaneous PTL, reinforcing the theory that PTX3 plays a role in the innate immune response during gestational complications associated with infectious/inflammatory conditions. © 2014 Elsevier Ireland Ltd.

The stroma plays a fundamental role in the function of different glandular systems. In the prostate, the stroma is responsible for the development and maintenance of the differentiated state of the epithelium. Nicotine induces tobacco dependence and promotes morphological alterations in the epithelial compartment. However, its effects on the prostate stroma are unclear. The objective of this study was to evaluate the morphology of the stromal microenvironment in the ventral prostate lobe of rats submitted to chronic nicotine administration. Twenty rats (Rattus norvegicus) were divided into two groups: 10 animals received subcutaneous nicotine and 10 animals received physiological saline by the same route. After treatment, samples were collected from the ventral prostate lobe, processed and submitted to histology, histochemistry, and ultrastructural analysis by transmission and scanning electron microscopy. The level of circulating testosterone was also analyzed. The results showed a significant increase in the density of type I collagen (56.3% to 85.9%, P < 0.01) and a decrease in the density of type III collagen (43.7% to 14.1%, P < 0.01). In addition, there was a qualitative increase in elastic fibers and in the number of smooth muscle cells with a secretory phenotype. Circulating testosterone levels were significantly reduced (898.3 to 363.1 ng/mL, P < 0.01). The results showed that nicotine modifies different components of the prostate stroma, suggesting that this drug is a risk factor for morphofunctional alterations in the prostate gland. © 2011 Wiley Periodicals, Inc.

Background: Chronic uncomplicated musculoskeletal pain in the spine (cervical, thoracic or lumbar) is highly prevalent and may severely limit the daily activities of those affected by it. Objective: To evaluate the efficacy and safety of treatment with auriculopressure applied to patients with non-specific spinal pain. Methods: A multicentre randomised controlled trial with two parallel arms (true auriculopressure (TAP) and placebo auriculopressure (PAP)) was performed. The intervention phase lasted 8 weeks and outcomes were measured 1 week after the last intervention (T1) and 6 months after baseline (T2). The primary outcome measure was change in pain intensity according to a 100 mm visual analogue scale (pain VAS) at T1. Secondary outcome measures were the Lattinen index, the McGill Pain Questionnaire and the SF-12 health-related quality of life scale (Spanish version in every case). Results: There were 265 participants (TAP group, n=130; PAP group, n=135). Pain was most frequently located in the upper back (55.1%, n=146), followed by the lower back (25.3%, n=67) and the dorsal area (12.5%, n=33). Nineteen patients (7.2%) reported pain affecting the entire spine. There were statistically significant differences between TAP and PAP in the change in the pain VAS at T1 of 10 mm (95% CI 2.8 to 17.3, p=0.007) and in the change in the pain VAS at T2 of 7.2 mm (95% CI 0.02 to 14.3, p=0.049) in favour of TAP. We also observed a statistically significant difference of 3.4 points in the physical component of the SF-12 in favour of TAP at T2 (95% CI 0.45 to 6.3, p=0.024). No severe adverse effects were detected or reported during treatment. Conclusions: The application of auriculopressure in patients with non-specific spinal pain in primary healthcare is effective and safe, and therefore should be considered for inclusion in the portfolio of primary healthcare services.

One of the challenges in screening for dementia in developing countries is related to performance differences due to educational and cultural factors. This study evaluated the accuracy of single screening tests as well as combined protocols including the Mini-Mental State Examination (MMSE), Verbal Fluency animal category (VF), Clock Drawing test (CDT), and Pfeffer Functional Activities Questionnaire (PFAQ) to discriminate illiterate elderly with and without Alzheimer's disease (AD) in a clinical sample. Cross-sectional study with 66 illiterate outpatients diagnosed with mild and moderate AD and 40 illiterate normal controls. Diagnosis of AD was based on NINCDS-ADRDA. All patients were submitted to a diagnostic protocol including a clinical interview based on the CAMDEX sections. ROC curves area analyses were carried out to compare sensitivity and specificity for the cognitive tests to differentiate the two groups (each test separately and in two by two combinations). Scores for all cognitive (MMSE, CDT, VF) and functional assessments (PFAQ) were significantly different between the two groups (p < 0.001). The best screening instruments for this sample of illiterate elderly were the MMSE and the PFAQ. The cut-off scores for the MMSE, VF, CDT, and PFAQ were 17.5, 7.5, 2.5, and 11.5, respectively. The most sensitive combination came from the MMSE and PFAQ (94.1%), and the best specificity was observed with the combination of the MMSE and CDT (89%). Illiterate patients can be successfully screened for AD using well-known screening instruments, especially in combined protocols. © 2011-IOS Press and the authors. All rights reserved. Source
