BACKGROUND: Postprandial lipemia (PPL) is a metabolic phenomenon that is correlated with atherogenesis. Although exercise lowers the triglycerides (TG) curve resulting from LLP, its acute effect has not yet been fully clarified.
OBJECTIVE: To discover whether Short Duration High Intensity Interval Training (SDHIIT) lowers the (TG) curve resulting from LLP among young people who exercise irregularly.
METHODS: A prospective analytical study analyzed 32 individuals (14 men) with an average age of 25±3.3 years and no metabolic alterations who underwent a cardiopulmonary exercise test and two PPL tests: Basal (PPLT-B) and Exercise (PPLT-E). Blood samples were collected for TG measurements at intervals of 0 minutes (fasting) and 30 minutes, and after ingestion of a lipid compound (50 g) at 90 minutes, 210 minutes and 270 minutes. After the fasting blood collection, an SDHIIT session was completed on a treadmill for the PPLT-E at 40% VO2max.
RESULTS: The PPLT-B and PPLT-E values for fasting, 30 minutes, 90 minutes, 210 minutes and 270 minutes were respectively: 69±34 mg/dL vs. 72±34 mg/dL (p= 0.4348); 68±34 mg/dL vs. 71±34 mg/dL (p=0.4771); 78±37 mg/dL vs. 77±34 mg/dL (p=0.8457); 124±57 mg/dL vs. 124±53 mg/dL (p=0.9525); and 120±64 mg/dL vs. 124±65 mg/dL (p=0.6636), finding no significant difference.
CONCLUSION: The results show that the lipid curve resulting from PPL among young people exercising irregularly is not modified by SDHIIT.

BACKGROUND: Recent studies show that women taking oral contraceptives (OC) have higher triglyceride and low-density lipoprotein levels than women not taking CO. Although the long-term clinical consequences of this increase are still unknown, studies suggest that higher levels of low-density lipoproteins contribute directly to vascular inflammation. One of the most effective ways of measuring vascular inflammation is through high sensitivity C-reactive protein (CRP).
OBJECTIVE: To examine whether the CRP levels of women taking OC are higher than those of women not taking OC.
METHODS: Study conducted at the Bahia Social Work College, Salvador, Bahia State - Brazil between July and December 2012, including apparently healthy women between 18 and 28 years old, eutrophic, classified as irregularly active and with fasting triglycerides below 150mg/dL. The sample was divided into two groups: an NOC group of women who not taking any type of hormone-based contraceptive and an OC group of women taking continuous low-dose OC for at least one year. After fasting for 12 hours, 5mL of blood were collected to measure their CRP levels.
RESULTS: 44 women were selected and divided equally between the groups, aged 24.0±2.9, BMI 21.0±3.2kg/m2. The median and interquartile CRP deviations in the NOC group and the OC group were respectively 0.5mg/L (0.0 to 0.9) and 2.1mg/L (0.9 to 3.2), with a statistically significant difference (p=0.002).
CONCLUSION: In this study, the CRP levels of women taking oral contraceptives were significantly higher than those of women not taking oral contraceptives.

BACKGROUND: Studies indicate that during postprandial lipemia (PPL), free radical formation occurs, stimulating the endothelium to secrete cytokines that mediate inflammatory responses. Excess adipose tissue, especially in the abdominal region, is positively correlated with C-reactive protein (CRP) values. However, little is known about CRP variations during the initial phase of PPL, especially among obese individuals.
OBJECTIVE: To determine if there are variations in CRP plasma concentrations among individuals with central obesity during the initial phase of PPL.
METHODS: This study assessed forty sedentary men and women with no alterations to fasting lipid profiles and waist circumferences above the normal cutoff point, measuring their CRP levels after fasting for twelve hours and three hours after ingesting 50g of fat.
RESULTS: The mean CRP values after fasting and three hours after lipids intake were 0.6 mg/L (0.2 to 1.8 mg/L) and 0.4 mg/L (0.2 to 1.8 mg/L) (p=1.000) respectively.
CONCLUSION: In this study, the initial phase of PPL did not present any variations in CRP concentrations among subjects with central obesity.

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: Recent studies have shown probable benefits of high intensity, predominantly anaerobic activities in fat oxidation capacity. However, the effect of predominantly anaerobic exercise in reducing obesity and inflammatory condition is still little known.
OBJECTIVES: To assess the effects of aerobic vs. anaerobic training on the levels of C-reactive protein (CRP) in women with central obesity, and the association of CRP levels with body composition.
METHODS: Randomized clinical trial with a population composed of adult, sedentary women with central obesity, enrolled at the Teaching-Care Outpatient Facility of Escola Bahiana de Medicina e Saúde Pública. A group of 19 women was randomly divided into two groups: Continuous training (CT - intensity at 20% of the ventilatory threshold - VT) or Interval Training (IT - 2-minute stimulus at 120% of VT and 2-minute recovery at 80% of VT) for 10 weeks, twice a week, 20-40-minute sessions. A medical and physical, laboratory and cardiopulmonary assessment was carried out before and after the intervention.
RESULTS: Median CRP levels were, respectively, before and after training: CT: 2.2 mg/L (0.6-4.1 mg/L) vs. 2.1 mg/L (0.8-5.5 mg/L) p=0.75; IT: 3.9 mg/L (0.7-8.6 mg/L) vs. 3.2 mg/L (1.2-5.7 mg/L) p=0.90. There was no significant difference when comparing the delta (Δ) CRP levels between groups, p=0.49. There was no association between CRP levels and other pre-intervention variables.
CONCLUSION: Low-volume exercise programs, regardless of their intensity, do not change CRP levels in women with central obesity.

In the last two decades, the understanding of adipose tissue biology underwent revolutionary changes, from a major energy storage site to an important endocrine organ responsible for the production and secretion of proteins, peptides and non-bioactive peptides. Among the proteins secreted by adipocytes, adiponectin (APN) is the most abundant, with important physiological actions in the cardiovascular and endocrine system, involving the sensitization of insulin action and regulation of body energy metabolism, including the heart. This review aims to describe the action of APN on the cardiovascular system. It includes original manuscripts with humans or animals. The databases PubMed and Medline, from years 1994 to 2013, were searched. Case reports, pilot studies or review studies have not been included. The health science descriptors and MeSH specific for Medline were used as keywords. The following cross searches were carried out: Adiponectin AND Obesity, Adiponectin AND Metabolism and Adiponectin AND Cardiovascular Disease. We found 303 manuscripts, excluded 204 and selected 31 manuscripts that were included this study. In the general context of this review, APN presents anti-inflammatory and ateroprotector effects in the vascular tissue and an insulin sensitizing action in tissues involved in glucose and lipid metabolism. It is thus considered an important biomarker for the development of cardiovascular diseases.

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.
