Fibrates are a class of lipid-lowering medication primarily used as second-line agents behind statins. Acting via the peroxisome proliferators-activated receptor-alpha, their main lipoprotein effects are to lower serum triglyceride levels and to raise high-density lipoprotein-cholesterol, with modest effects on low-density lipoprotein-cholesterol. However, many clinical trials indicate that fibrates may have benefits beyond simply altering one's lipid profile. Several angiographic studies show retardation in the progression of atherosclerotic lesions in coronary vessels. Although clinical trials have failed to show a reduction in mortality with fibrates, several post hoc analyses indicate that there may be a mortality benefit in patients with features of the metabolic syndrome. Given that fibrates are often used as second-line agents, it is essential they are safe to be given in combination with other agents, particularly statins and ezetimibe. Although the side-effect profile of fibrates includes gastrointestinal symptoms, increased liver function tests, a reversible rise in creatinine and myositis, in general, fibrates seem to be safe to use in combination with other lipid lowering medications. Thus far, fibrates have not shown a mortality benefit in randomized clinical trials; as a result, they cannot be considered first-line medication for the primary or secondary prevention of coronary artery disease.
Background and Objectives:Symptomatic uterine fibroids are a societal and healthcare burden with no clear consensus among medical professionals as to which procedural treatment is most appropriate for each symptomatic patient. Our purpose was to determine whether recommendations can be made regarding best practice based on review and analysis of the literature since 2006.Database:A systematic search of journal articles relevant to the treatment of symptomatic uterine fibroids was performed within PubMed, clinical society websites, and medical device manufacturers' websites. All clinical trials published in English, representing original research, and reporting clinical outcomes associated with interventions for the management of symptomatic uterine fibroids were considered. Each article was screened and selected based on study type, content, relevance, American College of Obstetricians and Gynecologists score, and internal/external validity. Outcomes of interest were patient baseline characteristics, fibroid characteristics, procedural details, complications, and long-term follow-up. Random-effects meta-analyses were used to test the quantitative data. Assessment of 143 full-length articles through January 2016 produced 45 articles for the quantitative analysis. The weighted combined results from hysterectomy trials were compared with those from uterine-preserving fibroid studies (myomectomy, uterine artery embolization, laparoscopic radiofrequency ablation, and magnetic resonance-guided focused ultrasound).Conclusion:We explored trends that might guide clinicians when counseling patients who need treatment of symptomatic fibroids. We found that fibroid therapy is trending toward uterine-conserving treatments and outcomes are comparable across those treatments. Since minimally invasive options are increasing, it is important for the clinician to provide the patient with evidence-based therapeutic strategies.
Natural FET in ovulatory women after IVF-PGS is associated with increased implantation and live birth rates compared to programmed FET in anovulatory women. Further investigation is needed to determine whether these findings hold true in other patient cohorts.
Aim:To investigate whether anti-Müllerian hormone (AMH) is associated with IVF cycle outcomes in young patients with diminished ovarian reserve. Materials & methods: Retrospective study of patients <35 years of age undergoing fresh IVF who had at least two 8-cell, day-3 embryos transferred with grades 1, 1.5 or 2. Patients were subgrouped, a priori, based on serum AMH levels: <1 or >1 ng/ml and <0.5 or >0.5 ng/ml. Results: In total, 1005 patients were included. Patients in the >1 ng/ml group required lesser gonadotropins compared with the <1 ng/ml and the <0.5 ng/ml group. More oocytes were retrieved from the same group compared with the latter two (p < 0.001). Despite these differences, the overall rates of clinical pregnancy, spontaneous abortion and live birth were comparable between the two groups. Conclusion: In patients with diminished ovarian reserve who have good quality embryos, AMH is not associated with clinical pregnancy, spontaneous miscarriage or live birth rates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
