BACKGROUND: Although observational studies suggest that exercise has anti-inflammatory effects, this possibility has not been confirmed definitively through randomized clinical trials.
OBJECTIVE: To assess the effects of aerobic activities on systemic inflammatory processes among people at cardiovascular risk.
METHODS: A randomized clinical trial encompassing sedentary subjects with at least two risk factors for heart disease or established cardiovascular disease. These volunteers were assigned randomly to three months of supervised aerobic training (training group) or just counseling on healthy lifestyle habits (control group). C-reactive protein (CRP) was measured by a highly sensitive method before and after these interventions.
RESULTS: Assessing 68 subjects. The training and control groups had similar baseline characteristics. There was improvement in functional capacity among only the training group patients. After three months, an increase in the CRP was noted in the control group, whose median rose from 2.2mg/L (IQR=1.0 to 4.3mg/L) to 3.2mg/L (IQR=2.4 to 5.5mg/L) - p=0.006. This phenomenon was not found in the training group, which presented a baseline median of 1.7mg/L (IQR =0.97 to 4.8mg/L), statistically similar to the final value of 2.5mg/L (1.0 to 4.7mg/L) - p=0.46. When the percentage variation in the CRP was compared for these groups, there was a greater increase in the control group (+58%, IQR=11% to 151%), compared to the training group (+17%, IQR= -36% to 79%) - intergroup p=0.046.
CONCLUSION: An aerobic exercise program seems to lessen CRP elevation among people at cardiovascular risk.

BACKGROUND: Women taking oral contraceptives (OC) have higher fasting lipid profile, postprandial lipemia (PPL) and C-reactive protein (CRP) than women not taking OC. Exercise has shown good results in controlling lipid and inflammatory levels.
OBJECTIVE: To compare fasting lipid, PPL and CRP levels among regularly active and irregularly active women taking OC.
METHODS: The study evaluated forty-four women taking OC, from the city of Salvador, BA, stratified into two groups: active group (AG; n=22), composed of physically active women and irregularly active group (IAG; n=22) composed of irregularly active women. In both groups, after 12-hour fasting, fasting lipid profile and CRP were assessed. Then, the volunteers took a compound containing 25 g fat and triglycerides were measured to check PPL. Mann-Whitney's test was used to compare PPL and CRP.
RESULTS: The delta values of triglycerides representing PPL respectively for the AG and the IAG were: 93±38.4 mg/dL vs. 163±49.6 mg/dL and 89±50.9 mg/dL vs. 156±47.6 mg/dL (p<0.01). The CRP values respectively for the AG and the IAG were: 1.1 mg/L (0.4-2.1 mg/L) and 2.1 mg/L (0.8-3.4 mg/L) (p=0.04).
CONCLUSION: In this study, physically active women taking OC presented triglycerides and fasting LDL, PPL and CRP significantly lower than irregularly active women taking OC.

BACKGROUND: Studies have shown limitations in the knowledge of academics and health professionals on a variety of clinical conditions. However, there is little research in the field of cardiovascular sciences.
OBJECTIVE: To identify and describe the level of knowledge of Physiotherapy graduates on chronic venous insufficiency (CVI).
METHODS: Descriptive cross-sectional observational study with graduates in the last year of physiotherapy undergraduate studies randomly selected from six higher education institutions. Data were collected through a self-administered structured questionnaire addressing academic education, clinical aspects and physiotherapy interventions on CVI. The students were grouped into: FSDA - universities where Angiology is not taught; FPNE - universities where a non-specialist professor teaches Angiology; and FPE - universities where a specialist professor teaches Angiology.
RESULTS: The evaluation covered 101 graduates. Of these, only 4.9% were familiar with of all the techniques and methods to diagnose CVI and 44.0% did not mention clinical examination as diagnostic evaluation. Of the 35 FPNE students, 18 (51.0%) did not mention clinical examination and 31.0% mentioned incorrect CVI diagnosing methods. Of the 19 FSDA students, 74.0% did not choose elastic compression as a means of treatment.
CONCLUSION: It was concluded that the evaluated graduates presented little knowledge on the main physiotherapy treatments and diagnostic methods for chronic venous insufficiency.

Studies show an association between the use of combined oral contraceptive (COC) and the elevation of C-reactive protein (CRP). However, it is unclear whether this increase represents cardiovascular risk, and what are the mechanisms involved in this association. Thus, our study aimed to review works that investigated the CRP levels in COC users, as well as describe the factors involved in this elevation. We considered eligible the studies indexed in EBSCO, EUROPUBMED, LILACS, PubMed and MEDLINE databases that evaluated the CRP of low-dose COC users, published between 2004 and 2015. The electronic search consisted of crossing the descriptors: Contraceptives, Oral, Combined; C-Reactive Protein and Inflammation, which resulted in 136 studies, of which 11 were eligible. They showed elevated CRP, even after ten days of use of COC. The most common CRP values were between 1-3 mg / L and > 3 mg / L, and in some studies values were greater than 10 mg / L. This indicates increased risk of future cardiovascular and metabolic events in this population. On the other hand, the main factors and mechanisms involved in the increase of this protein were hormonal, and, mainly, estrogenic and androgenic, and changes in function and levels of estrogen receptor β, high levels of cortisol and insulin resistance were documented. Other findings also indicate elevation of TNF-α, DNA hypomethylation in macrophages and alterations in the hepatic production of CRP. Finally, the COC represents, as does obesity, 20% of the variation of CRP of women of reproductive age.
