Even though platelet volume has been supposed to be indicator of platelet activation, contrasting results have been reported on its relationship with the extent of coronary artery disease (CAD). No data have been so far reported on Platelet-Large Cell Ratio (P-LCR). Thus, the aim of the current study was to investigate whether P-LCR is associated with CAD. We measured P-LCR in 1882 consecutive patients undergoing coronary angiography. Significant CAD was defined as stenosis >50% in at least 1 coronary vessel. We additionally measured Carotid Intima-Media Thickness (IMT) in 359 patients. The relationship between P-LCR and platelet aggregation was evaluated by PFA-100 and Multiplate. Patients with higher P-LCR were older (P = 0.038), with larger prevalence of diabetes (P < 0.0001), dilated cardiomyopathy or valvular heart disease (P = 0.004) and less often family history of CAD (P = 0.045), more often on statins (P = 0.002), and diuretics (P = 0.016). P-LCR was significantly associated with baseline glycaemia (P = 0.001) and RBC count (P < 0.001), but inversely related to platelet count (P < 0.0001). P-LCR was not associated with the prevalence of CAD (adjusted P = 0.3) or its severity. In addition, P-LCR was not related to Carotid IMT or platelet aggregation in patients with or without aspirin therapy. This study showed that P-LCR is not related to platelet aggregation, aspirin resistance, the extent of CAD and carotid IMT. Thus, P-LCR can not be considered as a marker of platelet reactivity or a risk factor for CAD. 相似文献

Background
Natural killer cell-type lymphoproliferative disease of granular lymphocytes is a disorder characterized by chronic proliferation of CD3−CD16+ granular lymphocytes. By flow cytometry analysis, we previously demonstrated a dysregulation in killer immunoglobulin-like receptor (KIR) expression in natural killer cells from patients with this lymphoproliferative disease, the activating KIR receptors being mostly expressed. We also found that patients with natural killer cell-type lymphoproliferative disease of granular lymphocytes usually had KIR genotypes characterized by multiple activating KIR genes.Design and Methods
We investigated the mRNA levels of the KIR3DL1 inhibitory and the related KIR3DS1 activating receptors in 15 patients with natural killer cell-type lymphoproliferative disease of granular lymphocytes and in ten controls. These genes are usually expressed when present in the genome of the Caucasian population.Results
We demonstrated the complete lack of KIR3DL1 expression in most of the patients analyzed, with the receptor being expressed in 13% of patients compared to in 90% of controls (P<0.01). Interestingly, studies of the methylation patterns of KIR3DL1 promoter showed a significantly higher methylation status (0.76 ± 0.12 SD) in patients than in healthy subjects (0.49±0.10 SD, P<0.01). The levels of expression of DNA methyl transferases, which are the enzymes responsible for DNA methylation, did not differ between patients and controls.Conclusions
In this study we showed, for the first time, a consistent down-regulation of the inhibitory KIR3DL1 signal due to marked methylation of its promoter, thus suggesting that together with the increased expression of activating receptors, the lack of the inhibitory signal could also play a role in the pathogenesis of natural killer cell-type lymphoproliferative disease of granular lymphocytes. 相似文献93.

Abstract
Interpretation of prevertebral soft tissue swelling is generally thought to be invalid in the presence of an endotracheal
tube (ETT). There is however little scientific data to support this.
We evaluate the prevertebral soft tissue swelling of 43 traumatized patients that have had an endotracheal tube (ETT) placed
in the acute setting. A control group of 92 patients were also evaluated which had been subjected to acute trauma and no ETT.
There was a significant increase in soft tissue swelling (p < 0.0001) found in the ETT group at the C2 level compared to the
non-tube group. There was no significant difference between the two groups at the C4 and C6 levels.
We feel that interpretation of prevertebral swelling in the traumatized patient at the C2 level is invalid in the presence
of an ETT, and indeed is significantly increased after intubation despite no injury at this level. However, the interpretation
of soft tissue swelling at and below C4 remains a useful tool in the evaluation of an occult cervical injury. 相似文献

The role of plasma biomarkers in acute heart failure. Serial changes and independent prognostic value of NT-proBNP and cardiac troponin-T 总被引:1,自引:0,他引:1
Metra M Nodari S Parrinello G Specchia C Brentana L Rocca P Fracassi F Bordonali T Milani P Danesi R Verzura G Chiari E Dei Cas L 《European journal of heart failure》2007,9(8):776-786
AIMS: Brain natriuretic peptide (BNP), NT-proBNP and troponins are useful for the assessment of patients with heart failure. Few data exist about their serial changes and their prognostic value in patients with acute heart failure (AHF). METHODS AND RESULTS: NT-proBNP and troponin-T plasma levels were measured at baseline, after 6, 12, 24, 48 h and at discharge in 116 consecutive patients with AHF and no evidence of acute coronary syndrome. NT-proBNP levels were 4421 pg/mL at baseline, declined after 24 h and reached their nadir at 48 h (2703 pg/mL). Troponin-T was detectable in 48% of patients. During a median follow-up of 184 days, 52 patients died or had a non-fatal cardiovascular hospitalisation. At a multivariable analysis including clinical and echo-Doppler variables, NT-proBNP plasma levels at discharge, detectable troponin-T plasma levels, and NYHA class at discharge were the only independent prognostic factors. CONCLUSION: In patients with AHF, NT-proBNP levels decline 24 h after the initiation of intravenous therapy and troponin-T is detectable in 48% of cases. NT-proBNP levels at discharge, detectable troponin-T levels, NYHA class and serum sodium have independent prognostic value. 相似文献

We report an unusual case of primary amyloidosis of the stomach in a patient complaining of dyspeptic symptoms. The diagnosis was confirmed histologically and other gastrointestinal site or systemic involvement was ruled out, Uncharacteristic dyspeptic symptoms may hide this rare metabolic disease. 相似文献

BACKGROUND: This study estimated the healthcare resource utilisation and costs of chronic obstructive pulmonary disease (COPD) patients, staged by severity, in the Italian pneumology departments (PDs). METHODS: The project was a multi-centre observational study conducted in 11 Italian PDs throughout the country. A total of 268 patients were recruited and followed prospectively for 1 year. For the purpose of analysis, patients were divided into four groups according to the severity at onset: mild COPD (stage I)-postbronchodilator FEV1/FVC <70% and FEV1 >or=80% of predicted; moderate COPD (stage II)-postbronchodilator FEV1/FVC <70% and 50% 相似文献

We used a CAPSIT-based questionnaire to estimate the percentage of parkinsonian patients suitable for subthalamic nucleus (STN) deep brain stimulation (DBS) in a movement disorders clinic. We found that out of 641 consecutive PD patients only 1.6% fulfilled strict STN-DBS criteria. When we applied more flexible criteria, the percentage of eligibility increased to 4.5%. Most patients (60%) were ineligible because they did not satisfy multiple questionnaire items. Items related to disease severity were responsible for the largest number of exclusions. This knowledge will help make decisions on resource allocation in centres wishing to start DBS surgery. 相似文献
