Objective: Quality improvement of health care requires robust measurable indicators to track performance. However identifying which indicators are supported by strong clinical evidence, typically from clinical trials, is often laborious. This study tests a novel method for automatically linking indicators to clinical trial registrations. Design: A set of 522 quality of care indicators for 22 common conditions drawn from the CareTrack study were automatically mapped to outcome measures reported in 13 971 trials from ClinicalTrials...

Endocrine disrupting contaminants, in combination with other environmental variables, are associated with altered reproductive health. Assisted reproductive technology (ART) procedures offer valuable opportunities to explore the connections between environmental contaminants in the ovarian microenvironment and measures of fertility, including impaired responsiveness to gonadotropins. Here, we investigate an emerging class of environmental contaminants, the perfluorinated alkyl acids (PFAAs), to determine whether ovarian contaminant levels are associated with measures of ovarian responsiveness and fertility outcomes in a South Carolina population of women undergoing ART...

Calcific aortic stenosis (AS) plays a critical role in the risk of cardiovascular disease. This preliminary study examined the relationship between the ex vivo valve thickness/calcification and in vivo clinical outcomes of Chinese patients with calcific AS. Six Chinese patients (3 patients with tricuspid aortic valves (TAV)) and 3 patients with. bicuspid aortic valves (BAV) with calcific AS undergoing heart valve replacement were initially chosen for this study. In vivo medical imaging of these calcific AS patients was evaluated using computed tomography and echocardiography...

Over the past decade we have seen significant changes in the biological characterization and strategies for treatment of mantle cell lymphoma (MCL). MCL is heterogeneous a disease, and so are the people that have it; although guidelines are appropriate, therapeutic approaches must be individualized based on a variety of factors. In this review, we summarize data on the range of therapeutic options, from observation in patients with slowly progressive low-tumor-burden MCL, to bendamustine-based regimens in typical MCL, to high-dose cytarabine-based regimens in young, fit patients...

PURPOSE: Although large-scale randomised clinical trials have established that radiotherapy (RT) - alone or combined with hormonal therapy (HT) - is effective in reducing the risk of ipsilateral breast tumour recurrence (IBTR), overall survival does not seem to be improved by adjuvant therapies. We sought to ascertain whether specific criteria can be adopted to avoid RT with an acceptable rate of IBTR after breast-conserving surgery (BCS) achieving tumour-free margins. PATIENTS AND METHODS: This non-randomised prospective study concerned the outcome of patients who underwent BCS for ductal carcinoma in situ (DCIS) and were prospectively assessed by means of an established scoring system based on width of free margins in association with age <40, presence of comedonecrosis, high grade, ER negativity and HER2 positivity, to orient the use of any adjuvant therapies...

In phase II platform trials, 'many-to-one' comparisons are performed when K experimental treatments are compared with a common control to identify the most promising treatment(s) to be selected for Phase III trials. However, when sample sizes are limited, such as when the disease of interest is rare, only a single Phase II/III trial addressing both treatment selection and confirmatory efficacy testing may be feasible. In this paper, we suggest a two-step safety selection and testing procedure for such seamless trials...

Bacteria of the Burkholderia cepacia complex (Bcc) can cause devastating pulmonary infections in cystic fibrosis (CF) patients, yet the precise mechanisms underlying inflammation, recurrent exacerbations and transition from chronic stages to acute infection and septicemia are not known. Bcc bacteria are generally believed to have a predominant extracellular biofilm life style in infected CF lungs, similar to Pseudomonas aeruginosa, but this has been challenged by clinical observations which show Bcc bacteria predominantly in alveolar macrophages...
