RESUMO

BACKGROUND: The patient self-management (PSM) is an effective approach for controlling the international normalized ratio, INR, within the therapeutic range. Nevertheless, most of the literature derives from randomized clinical trials, and no from routine clinical practice. The main objective of the present study was to evaluate long-term effectiveness and safety of PSM of oral anticoagulants (OACs) in real-world settings. METHODS: This prospective cohort study involved 808 patients who were trained for PSM between July 2009 and March 2012, and followed-up for a maximum observational period of 5 years. The follow-up consisted of a visit to the physician every 6 months. All patients used the same type of portable coagulometer, able to store digitally up to 100 INR measurements. Effectiveness outcomes included the percentage of patients within the therapeutic range, the time within therapeutic range (TTR), and the evolution of the TTR over 365 days of follow-up. Long-term safety profile of PSM included the incidence of all-cause deaths and complications (thromboembolic or hemorrhagic) reported between July 2009 and June 2014, and the time to event. RESULTS: The median follow-up was 3.3 years. The percentage of patients within therapeutic INR target range was 67.5%. The median TTR was 71.5%. The TTR increased over the follow-up period, either overall and regarding target INR. All-cause mortality was 2.4 per 100 patient-years (59 cases). The thromboembolic event rate was 0.9 per 100 patient-years (24 cases). The rate of major hemorrhages was 0.45 per 100 patient-years. Patients who drop out the PSM to perform the conventional management had greater rates of complications: 2.4, 1.8, and 3.4 per 100 patient-years for thromboembolic complications, major hemorrhagic events, and mortality, respectively. CONCLUSIONS: The PSM of OACs is effective for maintaining patients within the INR therapeutic range for a long period of time in routine clinical practice. Results of the present study suggest that its effectiveness is at least comparable to the conventional management. Moreover, it seems safe in real-world settings, by preventing all-cause mortality, and thromboembolic and major hemorrhagic complications. TRIAL REGISTRATION: This study was not a trial, thus registration was not required.

RESUMO

The clinical use of pulsed electromagnetic fields (PEMF) in osteoarticular pathology is widely extended, although the mechanisms involved are unknown. The aim of this study was to evaluate the action of a new protocol of treatment with PEMF on liquid medium cultures of fibroblast-like cells derivates of mononuclear peripheral blood cells. Fibroblast-like cells growth was obtained in liquid medium culture from mononuclear cells (MNC) of human peripheral blood. The PEMF irradiation protocol included an intensity of 2.25 mT, a frequency of 50 Hz and an application time of 15 min on days 7, 8 and 9 of cell culture. Immunophenotype was performed with specific heterologous monoclonal antibodies for each cell receptor (Vimentin, Cytokeratin, CD34, CD41, CD61 and CD68). The cytokines' production was determined in the supernatant of the culture medium by means of the Luminex technology. The immunophenotype did not show any statistical difference on comparing treated against non-treated cell cultures on any of the days. In the treatment cell population, the proinflammatory cytokines, IL-1ß and TNF-α showed a significant decrease on days 14 and 21 of the culture, whilst IL-10 increased significantly on day 21. It is concluded that PEMF irradiation does not alter the cell immunophenotype of the fibroblast-like cell population, but does provoke a decrease in the production of inflammatory-type cytokines (IL-1ß, TNF-α) and an increase in cytokines of lymphocytic origin (IL-10). These facts coincide with the chronology of the clinical effect undergone by patients with osteoarticular pathology after PEMF irradiation.

RESUMO

Nonclassical major histocompatibility complex (MHC) class I human leukocyte antigen E (HLA-E) and HLA-G molecules differ from classical ones by specific patterns of transcription, protein expression, and immunotolerant functions. The HLA-G molecule can be expressed as four membrane-bound (HLA-G1 to -G4) and three soluble (HLA-G5 to -G7) proteins upon alternative splicing of its primary transcript. In this study, we describe a new set of monoclonal antibodies (mAbs) called MEM-G/01, -G/04, -G/09, -G/13, MEM-E/02, and -E/06 recognizing HLA-G or HLA-E. The pattern of reactivity of these mAbs were analyzed on transfected cells by flow cytometry, Western blotting, and immunochemistry. MEM-G/09 and -G/13 mAbs react exclusively with native HLA-G1 molecules, as the 87G mAb. MEM-G/01 recognizes (similar to the 4H84 mAb) the denatured HLA-G heavy chain of all isoforms, whereas MEM-G/04 recognizes selectively denatured HLA-G1, -G2, and -G5 isoforms. MEM-E/02 and -E/06 mAbs bind the denatured and cell surface HLA-E molecules, respectively. These mAbs were then used to analyze the expression of HLA-G and HLA-E on freshly isolated cytotrophoblast cells, on the JEG-3 placental tumor cell line, and on cryopreserved and paraffin-embedded serial sections of trophoblast tissue. These new mAbs represent valuable tools to study the expression of HLA-G and HLA-E molecules in cells and tissues under normal and pathologic conditions.

RESUMO

OBJECTIVE: Atherosclerosis is a complex process characterized by an increase in vascular wall thickness owing to the accumulation of cells and extracellular matrix between the endothelium and the smooth muscle cell wall. There is evidence that females are at lower risk of developing cardiovascular disease (CVD) as compared to males. This has led to an interest in examining the contribution of genetic background and sex hormones to the development of CVD. The objective of this review is to provide an overview of factors, including those related to gender, that influence CVD. METHODS: Evidence analysis from PubMed and individual searches concerning biochemical and endocrine influences and gender differences, which affect the origin and development of CVD. RESULTS: Although still controversial, evidence suggests that hormones including estradiol and androgens are responsible for subtle cardiovascular changes long before the development of overt atherosclerosis. CONCLUSION: Exposure to sex hormones throughout an individual's lifespan modulates many endocrine factors involved in atherosclerosis.
