BACKGROUND: Recent trials in acute myocardial infarction indicate that intensive and early statin therapy that lowers low-density lipoprotein cholesterol (LDL-C) to < or = 70 mg dL(-1) is beneficial. The combination of statins with ezetimibe, a newly developed cholesterol-absorption inhibitor, can lead to a further reduction in LDL-C of up to 26%. In this study, we examined the rapidity and intensity of the lipid-lowering effect of ezetimibe co-administered with simvastatin immediately after myocardial infarction. MATERIALS AND METHODS: Sixty patients admitted for acute myocardial infarction were randomized to receive either simvastatin 40 mg (SIMVA), a combination of simvastatin 40 mg and ezetimibe 10 mg (EZE/SIMVA), or no lipid-lowering drugs (NLLD) and had their lipid levels assessed 2, 4 and 7 days later. RESULTS: At baseline, cardiovascular risk factors were similar in all three groups [mean (SD) LDL-C of 141 (36) mg dL(-1)]. At days 2 , 4 and 7 there was no significant change in mean LDL-C levels in the NLLD group (-10%, -6%, and -9%, all P > 0.09), while there were significant reductions with SIMVA (-15%, -27%, and -25%, respectively, all P < 0.001 vs. day 0) and even greater reductions with co-administration of EZE/SIMVA (-27%, -41%, and -51%, respectively, all P < 0.001 vs. day 0). The percentages of patients achieving LDL-C below 70 mg dL(-1) at days 4 and 7 were substantially greater with EZE/SIMVA (45% and 55%, respectively) than with SIMVA (5% and 10%, respectively), while no NLLD patient reached this goal. Triglyceride levels showed a progressive increase in the NLLD group (+45% at day 7, P < 0.05 vs. day 0), no change in the SIMVA group, but a decrease in the EZE/SIMVA group (-17% at day 7, P < 0.05 vs. day 0). No significant difference in HDL-C levels, tolerability, or clinical events was observed between the three groups. CONCLUSIONS: The co-administration of ezetimibe 10 mg with simvastatin 40 mg, by inhibiting cholesterol absorption and production, allowed more patients with acute myocardial infarction to reach LDL-C < or = 70 mg dL(-1) as early as the fourth day of treatment. The effects of such rapid and intense reduction in LDL-C on cardiovascular morbidity and mortality need to be evaluated in future clinical endpoint studies.  相似文献

Investigative studies of white matter (WM) brain structures using diffusion MRI (dMRI) tractography frequently require manual WM bundle segmentation, often called “virtual dissection.” Human errors and personal decisions make these manual segmentations hard to reproduce, which have not yet been quantified by the dMRI community. It is our opinion that if the field of dMRI tractography wants to be taken seriously as a widespread clinical tool, it is imperative to harmonize WM bundle segmentations and develop protocols aimed to be used in clinical settings. The EADC‐ADNI Harmonized Hippocampal Protocol achieved such standardization through a series of steps that must be reproduced for every WM bundle. This article is an observation of the problematic. A specific bundle segmentation protocol was used in order to provide a real‐life example, but the contribution of this article is to discuss the need for reproducibility and standardized protocol, as for any measurement tool. This study required the participation of 11 experts and 13 nonexperts in neuroanatomy and “virtual dissection” across various laboratories and hospitals. Intra‐rater agreement (Dice score) was approximately 0.77, while inter‐rater was approximately 0.65. The protocol provided to participants was not necessarily optimal, but its design mimics, in essence, what will be required in future protocols. Reporting tractometry results such as average fractional anisotropy, volume or streamline count of a particular bundle without a sufficient reproducibility score could make the analysis and interpretations more difficult. Coordinated efforts by the diffusion MRI tractography community are needed to quantify and account for reproducibility of WM bundle extraction protocols in this era of open and collaborative science.  相似文献

Background  

Acupuncture is a frequently used but controversial adjunct to the treatment of chronic low back pain (LBP). Acupuncture is now considered to be effective for chronic LBP and health care systems are pressured to make a decision whether or not acupuncture should be covered. It has been suggested that providing such services might reduce the use of other health care services. Therefore, we explored factors associated with acupuncture treatment for LBP and the relation of acupuncture with other health care services.  相似文献

Effective from spring 2004, new regulations for undergraduate medical education in Germany require a two-week practical training in general practice. Similar to other forms of medical education, this practical training should be regularly evaluated by students. With regard to special conditions of the training, we preferred a web based evaluation. Since adequate models were not available, we designed, implemented and tested an electronic way of evaluation. The following aspects turned out to be of special importance: teamwork, time, data protection and cost. Meanwhile, the evaluation is established and still accessible as demo-version for visitors of the home page. This electronic evaluation of medical training in general practice is highly appropriate for a timely evaluation allowing us to obtain a comparison between students' expectations and actual experience as well as a continuous supervision and to provide feedback to the participating practices. This is an important step for quality assurance of medical education in practices inside and outside the university.  相似文献

Objective: To assess the long-term survival, the incidence of cardiac complications and the factors that predict outcome in asymptomatic patients with severe degenerative mitral regurgitation (MR) undergoing mitral valve repair. Methods: Up to 143 asymptomatic patients (mean age 63 ± 12 years) with severe degenerative MR who underwent mitral valve repair between 1990 and 2001 were subsequently followed up for a median of 8 years. The study population was subdivided into three subgroups: patients with left ventricular (LV) dysfunction and/or dilatation (n = 18), patients with atrial fibrillation and/or pulmonary hypertension (n = 44) and patients without MR-related complications (n = 81). Results: For the patients, 10-year overall and cardiovascular survival was 82 ± 4% and 90 ± 3%. At 10 years, patients without preoperative MR-related complications had significantly better overall survival than patients with preoperative LV dysfunction and/or dilatation (89 ± 4% vs 57 ± 13%, log rank p = 0.001). Patients without preoperative MR-related complications also tended to have a better 10-year overall and cardiovascular survival than patients with atrial fibrillation and/or pulmonary hypertension (overall survival of 79 ± 8%), although this did not reach statistical significance (log rank p = 0.17). Cox regression analysis identified the baseline left ventricular ejection fraction and age as the sole independent predictors of outcome. Conclusion: Our data indicate that in asymptomatic patients with severe degenerative MR, mitral valve repair is associated with an excellent long-term prognosis. Nonetheless, the presence of preoperative MR-related complications, in particular LV dysfunction and/or dilatation, greatly attenuates the benefits of surgery. This suggests that mitral valve repair should be performed early, before any MR-related complications ensue.  相似文献

Oral administration is often difficult for tablets or capsules when patients have nausea, vomiting, dysphagia, deglutition disorder??Howewer, specifics dosages forms are avaible. This multidisciplinary approach has allowed to build a free practical guide for optimizing medical management for upper affected gastrointestinal system. We screened Vidal Hoptimal 2010 database to collect drugs with dosages forms adapted and build a booklet and an iPhone app for best supportive care in ambulatory care. Drugs are classified by pharmaceutical, dosage form, INN, trade mark.  相似文献

Background

Little is known about the amount of end of life care provided by general practitioners (GPs) in Germany. Therefore the aim of the HAVEL study is to describe the involvement of GPs in end of life care in more detail.

Methods

Data from all patients who died from natural causes within a period of 12 months (n?=?452) were collected from 30 general practices with a self-developed questionnaire and compared to data from patients who died in hospice or palliative care units.

Results

Contact rates with GPs increased at the end of life and approximately half of the patients (48?%) were seen within 48 h prior to death. A different spectrum of diseases and symptoms were observed compared to hospice and palliative care units with predominantly chronic diseases (e.g. cardiovascular and mental diseases).

Discussion and conclusions

General practitioners are highly involved in palliative health care, even for patients who eventually die in hospitals. Differences in patient characteristics and circumstances compared to specialized palliative care should be reflected in curricula for training in palliative care and the definition of a palliative situation.  相似文献
