Surgical treatments for vascular disease have progressed during the past century from autologous bypass conduits to synthetic materials, animal-derived tissues, cryopreserved grafts, and, finally, bioengineered conduits. In all cases, alternative vascular grafting materials have been developed with the goal of treating patients who have severe vascular disease requiring bypass but who have no suitable autologous conduit. Synthetic vascular grafts, animal-derived tissues, and cryopreserved grafts all have drawbacks in terms of availability and functionality that have limited their routine clinical adoption. Although bioengineered vascular graft technologies remain early and highly investigational, they have the potential to revolutionize the way in which severe vascular disease is treated. However, before they can have a clinical impact, bioengineered grafts must be available immediately and "off-the-shelf." 相似文献

In the USA, colorectal cancer is the third most common cancer and third leading cause of cancer death among both men and women. Declining rates of colon cancer in the past decade have been attributed in part to screening and removal of precancerous polyps via colonoscopy. Recent emphasis has been placed on measures to increase the quality and effectiveness of colonoscopy. These have been divided into pre-procedure quality metrics (bowel preparation), procedural quality metrics (cecal intubation, withdrawal time, and adenoma detection rate), post-procedure metrics (surveillance interval), and other quality metrics (patient satisfaction and willingness to repeat the procedure). The purpose of this article is to review the data and controversies surrounding each of these and identify ways to optimize the performance of colonoscopy. 相似文献

Background:
HBeAg negative hepatitis B infection exerts both inactive carrier state and chronic active hepatitis, which are sometimes difficult to differentiate. Serial hepatitis B virus (HBV) DNA quantification, alanine transaminase (ALT) measurement, and liver histology assessment can help to differentiate these forms of hepatitis B infection.Objectives:
We aimed to clarify the clinical and laboratory characteristics of HBeAg negative hepatitis B patients.Patients and Methods:
Patients with hepatitis B, referred to Tehran Blood Transfusion Hepatitis Clinic from 2011 to 2013, were included and followed for one year. Laboratory assessments including liver function tests, HBV DNA quantification, and liver biopsy (for some cases) were performed.Results:
Two hundred forty-three HBeAg negative hepatitis B patients were stratified into three groups based on to their HBV DNA level including group 1 (G1) with HBV DNA level < 2000 IU/mL, group 2 (G2) with HBV DNA level 2000-20000 IU/mL, and group 3 (G3) with HBV DNA level > 20000 IU/mL. The G2 had more similarity to G1 than G3 regarding their clinical characteristics.Conclusions:
It is concluded that most HBeAg negative hepatitis B patients with serum HBV DNA level of 2000-20000 IU/mL, persistent normal ALT concentration, and no or mild liver damage on biopsy can be clinically managed as HBV inactive carriers. 相似文献13.
Percutaneous Coronary Intervention for Bifurcation: How Can We Outperform the Provisional Strategy?

In the era of drug‐eluting stents, the provisional stenting strategy has been established as the default strategy in percutaneous coronary intervention for bifurcation lesions. However, emerging evidence shows that, in selected situations, the complex strategy of stenting both vessels regardless could reduce side‐branch restenosis without penalty. In particular, the double kissing crush technique has been proven to outperform the provisional strategy and other complex strategies in randomized trials. In this review, we present the evidence comparing the 2 strategies and individual stenting techniques and discuss the roles of other optimization techniques such as final kissing balloon inflation, proximal optimization technique, intravascular ultrasonography, and optical coherence tomography. Finally, we suggest a practical approach for choosing the optimal strategy for intervention with coronary bifurcation lesions. 相似文献

Heterozygous familial hypercholesterolemia (HeFH) is a genetic disorder that elevates low-density lipoprotein cholesterol and increases the risk of premature atherosclerotic cardiovascular disease (ASCVD). However, despite their atherogenic lipid profiles, the cardiovascular risk of HeFH varies in each individual. Their variety of phenotypic features suggests the need for better risk stratification to optimize their therapeutic management. The current review summarizes three potential approaches, including (1) definition of familial hypercholesterolemia (FH)-related risk scores, (2) genetic analysis, and (3) biomarkers. The International Atherosclerosis Society has recently proposed a definition of severe FH to identify very high-risk HeFH subjects according to their clinical characteristics. Furthermore, published studies have shown the association of FH-related genetic phenotypes with ASCVD, which indicates the genetic analysis’s potential to evaluate individual cardiovascular risks. Biomarkers reflecting disease activity have been considered to predict the formation of atherosclerosis and the occurrence of ASCVD in HeFH subjects. Incorporating these risk stratifications will be expected to allocate adequate intensity of lipid-lowering therapies in HeFH subjects, which ultimately improves cardiovascular outcomes. 相似文献

Purpose of Review
Gout management is currently suboptimal despite excellent available therapy. Gout patient education has been shown to enhance medication adherence and self-management, but needs improvement. We explored the literature on gout patient education including gaps in gout patient knowledge; use of written materials; in-person individual and group sessions; education via nurses, pharmacists, or multi-disciplinary groups; and use of phone, web-based, mobile health app, and text messaging educational efforts.Recent Findings
Nurse-led interventions have shown significant improvement in reaching urate goals. Pharmacist-led programs have likewise succeeded, but to a lesser degree. A multi-disciplinary approach has shown feasibility. Needs-assessments, patient questionnaires, and psychosocial evaluations can enhance targeted education.Summary
An interactive and patient-centered approach can enhance gout educational interventions. Optimal programs will assess for and address educational needs related to knowledge gaps, health literacy, race, gender, socio-economic status, and level of social support.20.
As a nation, we face a shortage of individuals to serve our aging population. Therefore, the recruitment of undergraduate students into gerontology programs is an important, although challenging task. The purpose of this study was to determine if students who do not choose to major in gerontology do so because they simply are unaware of the opportunities or because they are uninterested. College students who were not gerontology majors (N = 226) were surveyed to determine whether they were aware of a gerontology major at their university, whether they could define gerontology, and their reasons for not pursuing gerontology. Results suggest that a lack of awareness, rather than a lack of interest, may be responsible for the challenges of recruiting college students into the field of gerontology. This implies that the most efficient path to bolstering our gerontology workforce may be to make students aware of the diverse and rewarding career opportunities in the field of aging. 相似文献
