Introduction : Cardiovascular events (CE) due to atherosclerosis are preventable. Identification of high-risk patients helps to focus resources on those most likely to benefit from expensive therapy. Atherosclerosis is not considered for patient risk categorization, even though a fraction of CE...

Ibuprofen (IBU-H), a widely used anti-inflammatory, also shows a marked antimicrobial effect against several bacterial species, including those involved in cystic fibrosis such as Pseudomona aeruginosa, methicillin resistant Staphylococcus aureus and Burkholderia cepacia complex. Additionally, our results show significant synergy between water soluble Na-ibuprofen (IBU-Na) and ionic strength. Salt concentrations above 0.5 M modify the zeta potential promoting the action of Na-IBU; thus, with 1 M sodium chloride, IBU-Na is ten times more efficient than in the absence of ionic strength, and the minimum effective contact time is reduced from hours to minutes. In short time periods, where neither IBU-Na nor controls with 1 M NaCl show activity, the combination of both leads to a reduction in the bacterial load. We also analyzed whether the changes caused by salt on the bacterial membrane also promoted the activity of other microbicide compounds used in cystic fibrosis like gentamicin, tobramycin and phosphomycin. The results show that the presence of ionic strength only enhanced the bactericidal activity of the amphipathic molecule of IBU-Na. In this respect, the effect of saline concentration was also reflected in the surface properties of IBU-Na, where, in addition to the clear differences observed between 145 mM and 1 M, singular behaviors were also found, different in each condition. The combination of anti-inflammatory activity and this improved bactericidal effect of Na-IBU in hypertonic solution provides a new alternative for the treatment of respiratory infections of fibrotic patients based on known and widely used compounds.

Purpose The aims of this study were (1) to estimate the prevalence of cardiovascular disease risk factors among premenopausal and menopausal Argentinean women with and without type 2 diabetes mellitus and (2) to assess the contribution of total plaque area (TPA) to risk stratification when added to Framingham risk scores. Methods A descriptive cross-sectional study in primary prevention in 1257 women (ages 19-84 years) from Argentina. TPA was measured by ultrasonography. Framingham sex-specific risk equations were used to predict the risk of developing cardiovascular disease, coronary heart disease, and stroke during the next 10 years. Patients were divided into diabetic (n = 293) and control groups (n = 964), and then each group was divided according to age (>40, 40–49, 50–59, and ≥60 years). Findings No difference was observed between diabetic and control groups in the incidence of smoking or the presence of early family cardiovascular event. Overall, diabetic patients had higher body mass index, blood pressure, and TPA versus the control group. The Framingham risk score was higher in the diabetic group in all age groups. The mean (SD) coronary heart disease scores for the diabetic group at <40, 40 to 49, 50 to 59, and ≥60 were 6% (1.7%), 19% (2.5%), 38% (2.0%), and 60% (1.5%), respectively, whereas the scores in the control group 3% (0.8%), 7% (0.9%), 17% (0.9%), and 40% (0.9%), respectively. The stroke score was also enhanced in diabetic women, independent of their age. These data indicate that diabetic women in the premenopausal age or the early years of menopause age (40-50 years) are at intermediate or higher risk of developing a cardiovascular event. Implications Premenopausal diabetic women should be considered at possibly high risk of cardiovascular events compared with nondiabetic women. Direct assessment of atherosclerotic burden, such as TPA, should be used early in this population instead of relying on traditional risk scores.
