Oxytocin discontinuation after the active phase of labor is established

Despite the widespread usage of oxytocin, there is still no consensus on its mode of administration. The scope of the present meta-analysis was to assess the effect of oxytocin discontinuation after the active phase of labor is established on maternal fetal and neonatal outcomes. We searched Medline, Scopus, Popline, ClinicalTrials.gov and Google Scholar databases. Eight studies were finally retrieved, which involved 1232 parturient. We observed significantly decreased rates of cesarean sections among parturient that discontinued oxytocin (OR 0.51, 95% CI 0.35, 0.74) as well as decreased rates of uterine hyperstimulation (OR 0.33, 95% CI 0.19, 0.58). Similarly, cases of non-reassuring fetal heart rates were fewer among women that did not receive oxytocin after the establishment of the active phase of labor (OR 0.63, 95% CI 0.41, 0.97). Keeping in mind the aforementioned maternal and neonatal adverse effects that seem to result from infusion of oxytocin until delivery, future practice should aim towards its discontinuation after the establishment of the active phase of labor, as it does not seem to influence the total duration of labor. Future studies should aim towards specific populations of parturient in order to clarify whether different approaches are needed.     

Endothelial progenitor cell capture by stents coated with antibody against CD34: the HEALING-FIM (Healthy Endothelial Accelerated Lining Inhibits Neointimal Growth-First In Man) Registry

OBJECTIVES: This study was designed to evaluate whether rapid endothelialization of stainless steel stents with a functional endothelium prevents stent thrombosis and reduces the restenotic process. BACKGROUND: A "pro-healing" approach for prevention of post-stenting restenosis is theoretically favored over the use of cytotoxic or cytostatic local pharmacologic therapies. It is believed that the central role of the vascular endothelium is to maintain quiescence of the underlying media and adventitia. METHODS: Sixteen patients with de novo coronary artery disease were successfully treated with implantation of endothelial progenitor cell (EPC) capture stents. RESULTS: Complete procedural and angiographic success was achieved in all 16 patients. The nine-month composite major adverse cardiac and cerebrovascular events (MACCE) rate was 6.3% as a result of a symptom-driven target vessel revascularization in a single patient. There were no other MACCE despite only one month of clopidogrel treatment. At six-month follow-up, mean angiographic late luminal loss was 0.63 +/- 0.52 mm, and percent stent volume obstruction by intravascular ultrasound analysis was 27.2 +/- 20.9%. CONCLUSIONS: This first human clinical investigation of this technology demonstrates that the EPC capture coronary stent is safe and feasible for the treatment of de novo coronary artery disease. Further developments in this technology are warranted to evaluate the efficacy of this device for the treatment of coronary artery disease.     

Monoclonal Antibody Biosimilars in Oncology: Critical Appraisal of Available Data on Switching

Purpose

With the introduction of biosimilars of anticancer monoclonal antibodies (mAbs) in oncology, physicians are potentially confronted with the question whether it is clinically adequate to switch patients who are clinically stable on treatment with the reference product to a newly available biosimilar (or vice versa/from 1 biosimilar to another). For a proper impact assessment of switching, robust, product-specific, and clinically relevant evidence should be required, ideally including data from appropriately designed switching studies. In this article, we assess the current body of switching data available for approved or proposed biosimilars of anticancer mAbs.

Immune-mediated mechanisms of endothelial damage in atherosclerosis

The endothelium of the vessel wall as a barrier between blood and the subendothelial matrix proteins is essential for preventing thrombus formation and subsequent atherosclerosis development. Atherosclerosis is an inflammatory disease in which immune and autoimmune mechanisms are involved. Recently, it was demonstrated that endothelial cells in the vessel wall can be damaged not only by classic risk factors, such as hyperlipidemia, smoking and disturbed blood flow, but also (auto)immune reactions to autoantigens present in the cell surface, among which heat shock protein 60 (HSP60) was mostly studied. HSP60 normally located in mitochondria can be translocated into the cell member in response to stress stimuli. Meanwhile, autoantibodies against HSP60 are present in most subjects, especially patients with heart attack and stroke. These autoantibodies may bind to HSP60 expressed in endothelial cells resulting in the cell damage, subsequently initiating the formation of atherosclerotic lesions. Based on the recent progress in the research field, the present review will update the mechanisms of immune response to endothelial cells by which cell damage can initiate the development of atherosclerosis.
