Abstract: To evaluate the sensitivity and specificity of the usage of the FMF On-Line Risk Calculator with first-trimester ultrasound, in screening assessment for preeclampsia (PE), without serum markers. To define the best risk cut-off values for early, intermediate and late preeclampsia. Diagnostic accuracy study of pregnant women who had first-trimester ultrasounds between 11 and 13 weeks. The index test was the first-trimester ultrasound scan plus the FMF On-Line Risk Calculator to assess the risk for PE. The reference standard was the confirmation of actual development of early, intermediate or late PE. For calculations of sensitivity and specificity to determine the best cut-off values for early, intermediate and late PE, all the information was processed into ROC curves. The assessment of preeclampsia risk in the first trimester using an ultrasound plus the FMF On-Line Risk Calculator demonstrated a significant (p < 0.05) area under the ROC curve for early, intermediate and late preeclampsia. The best risk cut-off values were defined as 2.1% for early, 2.5% for intermediate and 3.5% for late preeclampsia. The first trimester US plus the FMF On-Line Risk Calculator tool was useful and applicable when assessing the risk for preeclampsia in a specific pregnant Brazilian population.

Abstract: Background: In recent years, so-called “non-ablative rejuvenation” has been carried out with the use of lasers or intense pulsed light (IPL) to stimulate collagen production by dermal fibroblasts. Intradermal infusion of CO2 stimulates fibroblasts and the synthesis of collagen and elastin, contributing to the retraction of the skin and tissue rejuvenation. Objectives: To evaluate the effects of IPL and the intradermal infusion of CO2 on fibroblast proliferation and collagen in the skin of female rats. Methods: Sixteen adult female Wistar rats were divided into two groups of eight animals. Group 1 underwent IPL and group 2 underwent intradermal CO2 infusion. There was a total of 8 weeks of treatment. We conducted a punch in each animal before any procedure (T0), another punch in the middle of treatment at 4 weeks post-procedure (T1) and a punch at the end of treatment at 8 weeks post-procedure (T2). The cells involved in inflammation, fibrosis and vascularization of the injured tissue by histopathology were analyzed. Results: There was statistically significant fibroblast proliferation and collagen proliferation noted when analyzing all 16 animals together and also when considering the two study groups separately. In both groups, the greatest proliferation of fibroblasts coincided with periods of increased collagen production. Conclusion: Both IPL and intradermal CO2 infusion stimulated fibroblast and collagen proliferation in the skin of the rats studied.

Abstract: this study aims to test the existence of near unit roots and local persistence in several important variables of economic models (product market, ccapm and black-scholes' formula). it is argued that the rejection of the unit root hypothesis will not necessarily imply in accepting a stationary and ergodic behavior for the time series. in order to do that, the near unit root model developed by phillips, moon and xiao (2001) was selected and an estimation strategy was used. such strategy is described as follows: a) the df-gls test, suggested by elliott, rothenberg and stock (1996); b) optimal selection of lags used by ng and perron (2001); c) the non parametric correction for terms of perturbation non i.i.d., from the kernel smoothing. the empirical results show, for some series, a characterization of the dgp from the local persistence.

Abstract: profound modifications in the profile of patients are currently being observed within the epidemic context of aids, especially with respect to pauperization and feminization of the disease. the population most frequently affected is in the reproductive age, and among adults aged 18 to 24 years, the ratio is 1 man to 1 woman, a phenomenon occurring uniformly all over the world. one of the main challenges for hiv-1-infected pregnant women and their doctors is the effect of the interaction between hiv infection and pregnancy. the present article is a review of the literature; and its objective is to assess the influence of hiv-1 infection seen from the maternal perspective, with a discussion of immunologic function, maternal prognosis, and the hiv-abortion interface. at present, we cannot conclude that pregnancy has a short-term effect on the evolution of hiv infection, but the concomitance of hiv and pregnancy may adversely affect the prognosis of gestation, especially in view of its frequent association with increased abortion and puerperal morbidity rates.
