Increasing the quality and quantity of geriatric medicine training for family practice residents is a particular challenge for community-based programs. These programs have an average of only seven full-time equivalent physician faculty. This report summarizes results of the Residency Assistance Program/Hartford Geriatric Initiative (RAP/HGI) geriatric medicine curriculum consultations for family practice (FP) residency programs conducted from 1996 to 2001. This project was developed as part of the RAP in family practice. Ten experienced FP educators were selected and trained as special consultants. Between 1996 and 2001, 39 FP residency programs participated in the 1- to 4-day RAP/HGI consultations. The programs were diverse in size and location. The consultations reached 308 family practice residency faculty members involved in training 807 residents. Program evaluations of the consultants were uniformly in the very good to excellent range, with a mean rating of 4.6 (5-point scale, with 5 indicating excellent). At the end of the initial consultation visit, the residency program faculty and the consultant developed short-term goals for geriatrics program development. Eighty-five percent (33/39) of the programs submitted their curriculum goals in writing. The mean number of goals per program was 4.8 (range = 3-11). Of the 33 programs with written goals, follow-up was documented for 29 programs. Seventy-nine percent of the programs' self-defined educational goals were met during the 6 to 12 months of follow-up (range 50-100%). Ten of the programs implemented all of their educational goals. The RAP/HGI project demonstrated that achievable geriatric medicine curriculum improvements could occur as part of an onsite consultation process. 相似文献

OBJECTIVES: We analyzed the effects of vascular brachytherapy (VBT) on ostial in-stent restenosis (ISR). BACKGROUND: In-stent restenosis has a high recurrence rate after percutaneous reintervention. The recurrence rate of ostial ISR lesions and the impact of VBT remain unknown. METHODS: We evaluated 133 patients with native coronary ostial ISR from a pooled database of 990 patients enrolled in randomized VBT trials. Independent quantitative angiography was performed at baseline and follow-up in 45 gamma, 27 beta, and 61 placebo patients. RESULTS: Binary restenosis was significantly higher in placebo than radiated patients (75.4% vs. 17.8% in gamma vs. 22.2% in beta, p < 0.0001). The treatment effect of both gamma (odds ratio [OR] 0.06; 95% confidence interval [CI] 0.02 to 0.17) and beta VBT (OR 0.10; 95% CI 0.03 to 0.31) was maintained after controlling for differences in baseline lesion length. Proximal and distal radiation edge restenosis rates were similar among the groups. Vascular brachytherapy of true aorto-ostial lesions (n = 34) was similarly beneficial: restenosis rates of placebo versus gamma or beta patients of 83.3% versus 6.7% versus 28.6%, p = 0.0002. CONCLUSIONS: Conventional treatment of ostial ISR is associated with a recurrence rate of over 75%. Vascular brachytherapy with either gamma or beta sources results in significant and similar reductions in restenosis compared with placebo. Similar benefits after VBT prevail in true aorto-ostial lesions. 相似文献

Although recent studies show that obesity, or elevated body mass index (BMI), is associated with lower levels of B-type natriuretic peptide (BNP), it is unknown whether BMI affects the prognostic value of BNP in heart failure (HF). This study confirms the relationship between high BMI and low BNP in patients with advanced systolic HF. Despite relatively lower levels of BNP in overweight and obesity, BNP predicts worse symptoms, impaired hemodynamics, and higher mortality in HF at all levels of BMI.OBJECTIVES: This study aimed to examine the influence of obesity on the predictive value of the B-type natriuretic peptide (BNP) assay in heart failure (HF). BACKGROUND: Recent studies show that obesity, or elevated body mass index (BMI), is associated with lower circulating levels of BNP both in the general population and in patients with HF. METHODS: We analyzed data from 316 systolic HF (left ventricular ejection fraction [LVEF] < or =40%) patients [age, 53 +/- 13 years; mean LVEF, 24 +/- 7%; 48% ischemic] followed up at a university HF center. Patients were divided into categories of BMI: lean (BMI <25 kg/m2), overweight (BMI = 25 to 29.9 kg/m2), and obese (BMI > or =30 kg/m2). RESULTS: The BNP levels were significantly lower in overweight and obese compared with lean patients (p = 0.0001); median BNP (interquartile range) for the lean (n = 131), overweight (n = 99), and obese (n = 86) groups was 747 (272 to 1,300), 380 (143 to 856), and 332 (118 to 617) pg/ml, respectively. In each BMI category, elevated BNP was significantly associated with worse symptoms and higher pulmonary capillary wedge pressure. Higher BNP was also a significant independent predictor of survival independent of BMI. Optimal BNP cutoff for prediction of death or urgent transplant in lean, overweight, and obese HF patients was 590, 471, and 342 pg/ml, respectively. CONCLUSIONS: Although BNP levels are relatively lower in overweight and obese HF patients, BNP predicts worse symptoms, impaired hemodynamics, and higher mortality at all levels of BMI. 相似文献

Background: Vertebrate body axis extension occurs in a head‐to‐tail direction from a caudal progenitor zone that responds to interacting signals. Wnt/β‐catenin signaling is critical for generation of paraxial mesoderm, somite formation, and maintenance of the axial stem cell pool. Body axis extension requires Wnt8a in lower vertebrates, but in mammals Wnt3a is required, although the anterior trunk develops in the absence of Wnt3a. Results: We examined mouse Wnt8a–/– and Wnt3a–/– single and double mutants to explore whether mammalian Wnt8a contributes to body axis extension and to determine whether a posterior growth function for Wnt8a is conserved throughout the vertebrate lineage. We find that caudal Wnt8a is expressed only during early somite stages and is required for normal development of the anterior trunk in the absence of Wnt3a. During this time, we show that Wnt8a and Wnt3a cooperate to maintain Fgf8 expression and prevent premature Sox2 up‐regulation in the axial stem cell niche, critical for posterior growth. Similar to Fgf8, Wnt8a requires retinoic acid (RA) signaling to restrict its caudal expression boundary and possesses an upstream RA response element that binds RA receptors. Conclusions: These findings provide new insight into interaction of caudal Wnt‐FGF‐RA signals required for body axis extension.

Each year over one million patients with acute heart failure (AHF) present to a United States emergency department (ED). The vast majority are hospitalized for further management. The length of stay and high postdischarge event rate in this cohort have changed little over the past decade. Therapeutic trials have failed to yield substantive improvement in postdischarge outcomes; subsequently, AHF care has changed little in the past 40 years. Prior research studies have been fragmented as either “inpatient” or “ED‐based.” Recognizing the challenges in identification and enrollment of ED patients with AHF, and the lack of robust evidence to guide management, an AHF clinical trials network was developed. This network has demonstrated, through organized collaboration between cardiology and emergency medicine, that many of the hurdles in AHF research can be overcome. The development of a network that supports the collaboration of acute care and HF researchers, combined with the availability of federally funded infrastructure, will facilitate more efficient conduct of both explanatory and pragmatic trials in AHF. Yet many important questions remain, and in this document our group of emergency medicine and cardiology investigators have identified four high‐priority research areas. 相似文献

In this study, 67 participants (95% female) with fibromyalgia (FM) were randomly assigned to an online acceptance and commitment therapy (online ACT)?and?treatment as usual (TAU; ACT + TAU) protocol or a TAU control condition. Online ACT?+?TAU participants were asked to complete 7 modules over an 8-week period. Assessments were completed at pre-treatment, post-treatment, and 3-month follow-up periods and included measures of FM impact (primary outcome), depression, pain, sleep, 6-minute walk, sit to stand, pain acceptance (primary process variable), mindfulness, cognitive fusion, valued living, kinesiophobia, and pain catastrophizing. The results indicated that online ACT?+?TAU participants significantly improved in FM impact, relative to TAU (P?<.001), with large between condition effect sizes at post-treatment (1.26) and follow-up (1.59). Increases in pain acceptance significantly mediated these improvements (P?=?.005). Significant improvements in favor of online ACT?+?TAU were also found on measures of depression (P?=?.02), pain (P?=?.01), and kinesiophobia (P?=?.001). Although preliminary, this study highlights the potential for online ACT to be an efficacious, accessible, and cost-effective treatment for people with FM and other chronic pain conditions.
Perspective
Online ACT reduced FM impact relative to a TAU control condition in this randomized controlled trial. Reductions in FM impact were mediated by improvements in pain acceptance. Online ACT appears to be a promising intervention for FM. 相似文献58.
