Introduction: Statins have several pleiotropic effects that have the potential to be beneficial during pregnancy. This study evaluates the available evidence for the teratogenicity of statins, and their utility in treating preeclampsia and dyslipidemia in pregnancy, as good alternatives in these domains are currently lacking.
Areas covered: The possible teratogenicity of statins is a primary focus of this paper. We also evaluated for some possible non-teratogenic effects, such as changes in birth weight and rates of spontaneous abortion, among mothers exposed to statins during pregnancy. Regarding potential uses, this study mainly discusses statin utility in preventing and treating preeclampsia and treating dyslipidemia in pregnancy. Within the latter, we explore the relationship between dyslipidemia and preeclampsia, the potential consequences of delaying statin therapy where indicated, and the impact of supra-physiological levels of cholesterol in utero on offspring. The literature search was conducted using Embase, Web of Science, PubMed, and Scopus.
Expert opinion: Based on current evidence, statins are likely not teratogenic. Limited, but promising evidence exists for their efficacy in treating and preventing preeclampsia. In utero exposure to high cholesterol may negatively impact offspring, and should be thoroughly investigated. 相似文献
Although it is accepted that an important correlation exists between the physical exercise and the oxidative stress status, the data regarding the levels of the main oxidative stress markers after physical training have been difficult to interpret and a subject of many controversies. There are also very few studies regarding the effects of short-time exercise on the oxidative stress status modifications. Thus, in the present report we were interested in studying the modifications of some oxidative stress markers (two antioxidant enzymes-superoxide dismutase and glutathione peroxidase, a lipid peroxidation parameter — malondyaldehide, the total antioxidant status and protein carbonyl levels), from the serum of rats that were subject to one bout of five minutes exercise on a treadmill, when compared to a control sedentary group. In this way, we observed a decrease of superoxide dismutase specific activity in the rats which performed the exercises. Still, no modifications of glutathione peroxidase specific activity were found between groups. In addition, increased levels of malondyaldehide and protein carbonyls were observed in the rats subjected to exercises. In conclusion, our data provides new evidence regarding the increase of the oxidative stress status, as a result of a 5-minutes bout of treadmill exercising in rats, expressed through a decrease in the SOD specific activity and the total antioxidant status and also an increase of the lipid peroxidation and protein oxidation processes. 相似文献
Introduction: A residual risk of morbidity and mortality from cardiovascular (CV) disease remains despite statin therapy. This situation has generated an interest in finding novel approaches of combining statins with other lipid-lowering agents, or finding new lipid and non-lipid targets, such as triglycerides, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, proprotein convertase subtilisin/kexin type 9 (PCSK9) gene, cholesterol ester transfer protein (CETP), lipoprotein (a), fibrinogen or C-reactive protein. Areas covered: The recent results from the IMProved Reduction of Outcomes: Vytorin Efficacy International Trial (IMPROVE-IT) demonstrated an incremental clinical benefit when ezetimibe, a non-statin agent, was added to simvastatin therapy. Expert opinion: The results from IMPROVE-IT revalidated the concept that low-density lipoprotein cholesterol (LDL-C) levels are a clinically relevant treatment goal. This trial also suggested that further decrease of LDL-C levels (53 vs. 70 mg/dl; 1.4 vs. 1.8 mmol/l) was more beneficial in lowering CV events. This “even lower is even better” evidence for LDL-C levels may influence future guidelines and the use of new drugs. Furthermore, these findings make ezetimibe a more realistic option to treat patients with statin intolerance or those who cannot achieve LDL-C targets with statin monotherapy. 相似文献
A number of 513 consecutive patients (494-haemophilia A and 19-haemophilia B) from eight haemophilia treatment centers have been investigated with Bethesda assay for the presence of factor VIII or IX inhibitors. The overall prevalence of inhibitors was 15.20%, 18.48% in severe, 5.60% in moderate and 12.24% in mild forms. The prevalence was higher than reported in most of the western countries. The age at start of substitution (p = 0.9775), the frequent switching of factor concentrates (p = 0.8931) were not relevant factors for the development of inhibitors. It is worth to be mentioned the unexpectedly occurrence of inhibitors in prior inhibitor negative (6/72) patients (during surgical interventions) probably due to their previous scarce substitution, occurrence which seems not being connected with the continuous infusion modality of factor VIII administration (p = 0.8341). In controversial situations, in the field of low titer (≤ 1 BU/ml) inhibitors for a reliable interpretation of the results the performance of recovery index and half-life time assessment of FVIII/IX was undertaken. 相似文献
We present the case of a 58-year old male patient admitted in the surgery section of the University Emergency Hospital of Bucharest and diagnosed with acute abdomen. The minimal clinical-paraclinical investigation (i.e., thorax-pulmonary Xray, biological probes) raises questions as to the differentiated diagnosis and other associated diseases, also suggesting the existence of voluminous diaphragmatic hernia. The CT thorax-abdomen examination confirms the diaphragmatic hernia suspicion, with intra-thorax ascent of the colon up to the anterior C4 level, but does not explain the abdominal suffering; thus we suspected a biliary ileus or acute appendicitis. Medial laparotomy was imperative. Intrasurgically peritonitis was noticed located by gangrenous acute apendicitis, perforated, with coprolite, for which apendictomy and lavage-drainage pf the peritoneal cavity was performed. Post-surgical status: favourable to recovery. 相似文献
BACKGROUND AND AIMS:: Pediatric ulcerative colitis (UC) shares many features with adult-onset disease but there are some unique considerations; therefore, therapeutic approaches have to be adapted to these particular needs. We aimed to formulate guidelines for managing UC in children based on a systematic review (SR) of the literature and a robust consensus process. The present article is a product of a joint effort of the European Crohn's and Colitis Organization (ECCO) and the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN). METHODS:: A group of 27 experts in pediatric IBD participated in an iterative consensus process including 2 face-to-face meetings, following an open call to ESPGHAN and ECCO members. A list of 23 predefined questions were addressed by working subgroups based on a SR of the literature. RESULTS:: A total of 40 formal recommendations and 68 practice points were endorsed with a consensus rate of at least 89% regarding initial evaluation, how to monitor disease activity, the role of endoscopic evaluation, medical and surgical therapy, timing and choice of each medication, the role of combined therapy, and when to stop medications. A management flowchart, based on the Pediatric Ulcerative Colitis Activity Index (PUCAI), is presented. CONCLUSIONS:: These guidelines provide clinically useful points to guide the management of UC in children. Taken together, the recommendations offer a standardized protocol that allows effective, timely management and monitoring of the disease course, while acknowledging that each patient is unique. 相似文献
