Background
The level of platelet reactivity (PR) inhibition obtained after P2Y12-ADP receptor antagonist loading dose (LD) is associated with the ischemic and bleeding risk following percutaneous coronary intervention (PCI) in acute coronary syndromes (ACS).Objective
We aimed to evaluate the level of PR inhibition achieved by a 180 mg LD of ticagrelor and the rate of high on-treatment platelet reactivity (HTPR) in ACS patients undergoing PCI.Methods
We performed a multicentre prospective observational study enrolling ACS patients undergoing PCI. Patients were included if they were admitted for ST-elevation myocardial infarction or non ST-elevation ACS. To assess PR, a VASP index was measured at least 6 and within 24 hours following a 180 mg LD of ticagrelor. HTPR was defined as a VASP index ≥ 50%.Results
One hundred and fifteen patients were included: 31.3% of STEMI, 49.6% of NSTEMI and 19.1% of unstable angina. Following ticagrelor LD the mean VASP index was 17 ± 14%. However the response to ticagrelor was not uniform with a small inter-individual variability: inter quartile range: 7.6–22.8% and a rate of HTPR of 3.5%. A high number of patients, 65.6%, had a VASP index < 16%. None of the baseline characteristics of the study population was associated with PR. In addition, PR was similar in STEMI, NSTEMI and unstable angina (p = 0.9).Conclusion
In ACS patients the level of PR inhibition achieved by a 180 mg loading dose of ticagrelor is not uniform and the rate of HTPR is 3.5%. A high proportion of patients exhibited a VASP index < 16%. 相似文献123.

Background
Assessment of pre-test probability of pulmonary embolism (PE) and prognostic stratification are two widely recommended steps in the management of patients with suspected PE. Some items of the Geneva prediction rule may have a prognostic value.We analyzed whether the initial probability assessed by the Geneva rule was associated with the outcome of patients with PE.Methods
In a post-hoc analysis of a multicenter trial including 1,693 patients with suspected PE, the all-cause death or readmission rates during the 3-month follow-up of patients with confirmed PE were analyzed. PE probability group was prospectively assessed by the revised Geneva score (RGS). Similar analyses were made with the a posteriori-calculated simplified Geneva score (SGS).Results
PE was confirmed in 357 patients and 21 (5.9%) died during the 3-month follow-up. The mortality rate differed significantly with the initial RGS group, as with the SGS group. For the RGS, the mortality increased from 0% (95% Confidence Interval: [0–5.4%]) in the low-probability group to 14.3% (95% CI: [6.3-28.2%]) in the high-probability group, and for the SGS, from 0% (95% CI: [0–5.4%] to 17.9% (95% CI: [7.4-36%]). Readmission occurred in 58 out of the 352 patients with complete information on readmission (16.5%). No significant change of readmission rate was found among the RGS or SGS groups.Conclusions
Returning to the initial PE probability evaluation may help clinicians predict 3-month mortality in patients with confirmed PE.(ClinicalTrials.gov: NCT00117169) 相似文献124.

Stem cells discovery and their potential have led to the emergence of new forms of therapy with the development of bio-engineering cell and tissue methods underlying future medicine. The availability of stem cells and their preservation thus become an issue for everyone's health. Among the different sources of stem cells, those in the dental pulp have the advantage of being pluripotent, they can be cryopreserved and stored for long periods without losing their multiplication and differentiation capacities and finally they are easily accessible. The wisdom or natal teeth extracted for medical reasons are an opportunity for everyone to preserve stem cells for an autologous use. Biobanks authorized and specialized in the preparation and storage of pulp stem cells provide access to autologous regenerative medicine of tomorrow. 相似文献

The presence of autoantibodies specific for nucleic acid-associated antigens is the hallmark of systemic lupus erythematosus (SLE). We have recently developed a specific inhibitor of TLR7 and TLR9, called immunoregulatory sequence (IRS) 954, and showed that it inhibits the induction of IFN-alpha by human plasmacytoid dendritic cells in response to DNA and RNA viruses and isolated immune complexes from lupus patients. In this study, we show that IRS 954 can prevent progression of disease when injected in the lupus prone (NZBxNZW)F1 mice. Following treatment, we observed a significant reduction of serum levels of nucleic acid-specific autoantibodies as well as decreased proteinuria, reduced glomerulonephritis, end-organ damage and increased survival. These data demonstrate that in addition to its ability to block IFN-alpha, IRS 954 can reduce symptoms in a lupus model and thus represents a promising therapeutic agent for the treatment of SLE. 相似文献

Background
Online resources are a source of information for parents of premature babies when their baby is discharged from hospital.Objectives
To explore what topics parents deemed important after returning home from hospital with their premature baby and to evaluate the quality of existing websites that provide information for parents post‐discharge.Methods
In stage 1, 23 parents living in Northern Ireland participated in three focus groups and shared their information and support needs following the discharge of their infant(s). In stage 2, a World Wide Web (WWW) search was conducted using Google, Yahoo and Bing search engines. Websites meeting pre‐specified inclusion criteria were reviewed using two website assessment tools and by calculating a readability score. Website content was compared to the topics identified by parents in the focus groups.Results
Five overarching topics were identified across the three focus groups: life at home after neonatal care, taking care of our family, taking care of our premature baby, baby's growth and development and help with getting support and advice. Twenty‐nine sites were identified that met the systematic web search inclusion criteria. Fifteen (52%) covered all five topics identified by parents to some extent and 9 (31%) provided current, accurate and relevant information based on the assessment criteria.Conclusion
Parents reported the need for information and support post‐discharge from hospital. This was not always available to them, and relevant online resources were of varying quality. Listening to parents needs and preferences can facilitate the development of high‐quality, evidence‐based, parent‐centred resources. 相似文献129.

Objective
To evaluate content and face validity of a collaboration readiness assessment tool developed to facilitate collaborative efforts to implement policy, systems, and environment changes in Supplemental Nutrition Assistance Program–Education (SNAP-Ed).Methods
Evaluation of the validity of the tool involved 2 steps. Step 1 was conducted with 4 subject matter experts to evaluate content validity. Step 2 used an iterative cognitive testing process with 4 rounds and 16 SNAP-Ed staff and community partners to evaluate face validity.Results
Subject matter experts found that survey items appropriately matched the content area indicated and adequately covered collective efficacy, change efficacy, and readiness. Cognitive testing with SNAP-Ed staff and partners informed modifications and resulted in adequate face validity.Conclusions and Implications
The ability to measure collaboration readiness will allow agencies and community partners that implement SNAP-Ed to target areas that facilitate collaboration efforts needed for policy, systems, and environment change and collective efficacy. Further cognitive testing of the tool with other populations is needed to ensure its applicability and usefulness. Evaluation of the reliability of the tool with a broad range of SNAP-Ed programs and community agencies is also recommended. 相似文献130.

Polyphenols may play a chemopreventive role in colorectal cancer (CRC); however, epidemiological evidence supporting a role for intake of individual polyphenol classes, other than flavonoids is insufficient. We evaluated the association between dietary intakes of total and individual classes and subclasses of polyphenols and CRC risk and its main subsites, colon and rectum, within the European Prospective Investigation into Cancer and Nutrition (EPIC) study. The cohort included 476,160 men and women from 10 European countries. During a mean follow-up of 14 years, there were 5991 incident CRC cases, of which 3897 were in the colon and 2094 were in the rectum. Polyphenol intake was estimated using validated centre/country specific dietary questionnaires and the Phenol-Explorer database. In multivariable-adjusted Cox regression models, a doubling in total dietary polyphenol intake was not associated with CRC risk in women (HRlog2?=?1.06, 95% CI 0.99–1.14) or in men (HRlog2?=?0.97, 95% CI 0.90–1.05), respectively. Phenolic acid intake, highly correlated with coffee consumption, was inversely associated with colon cancer in men (HRlog2?=?0.91, 95% CI 0.85–0.97) and positively associated with rectal cancer in women (HRlog2?=?1.10, 95% CI 1.02–1.19); although associations did not exceed the Bonferroni threshold for significance. Intake of other polyphenol classes was not related to colorectal, colon or rectal cancer risks. Our study suggests a possible inverse association between phenolic acid intake and colon cancer risk in men and positive with rectal cancer risk in women. 相似文献
