Obesity is frequently associated with a chronic low-grade inflammation in the adipose tissue (AT) and impaired glucose homeostasis. Adipose tissue macrophages (ATMs) have been shown to accumulate in the inflamed AT either by means of recruitment from the blood or local proliferation. ATM proliferation and activation can be stimulated by TH2 cytokines, such as IL-4 and IL-13, suggesting involvement of CD4-positive T cells in ATM proliferation and activation. Furthermore, several studies have associated T cells to alterations in glucose metabolism. Therefore, we sought to examine a direct impact of CD4-positive T cells on ATM activation, ATM proliferation and glucose homeostasis using an in vivo depletion model. Surprisingly, CD4 depletion did not affect ATM activation, ATM proliferation, or insulin sensitivity. However, CD4 depletion led to a significant improvement of glucose tolerance. In line with this, we found moderate disturbances in pancreatic endocrine function following CD4 depletion. Hence, our data suggest that the effect on glucose metabolism observed after CD4 depletion might be mediated by organs other than AT and independent of AT inflammation. 相似文献

Objectives
This study assessed the prognostic significance of remote zone native T1 alterations for the prediction of clinical events in a population with ST-segment elevation myocardial infarction (STEMI) who were treated by primary percutaneous coronary intervention (PPCI) and compared it with conventional markers of infarct severity.Background
The exact role and incremental prognostic relevance of remote myocardium native T1 mapping alterations assessed by cardiac magnetic resonance (CMR) after STEMI remains unclear.Methods
We included 255 consecutive patients with STEMI who were reperfused within 12 h after symptom onset. CMR core laboratory analysis was performed to assess left ventricular (LV) function, standard infarct characteristics, and native T1 values of the remote, noninfarcted myocardium. The primary endpoint was a composite of death, reinfarction, and new congestive heart failure within 6 months (major adverse cardiac events [MACE]).Results
Patients with increased remote zone native T1 values (>1,129 ms) had significantly larger infarcts (p = 0.012), less myocardial salvage (p = 0.002), and more pronounced LV dysfunction (p = 0.011). In multivariable analysis, remote zone native T1 was independently associated with MACE after adjusting for clinical risk factors (p = 0.001) or other CMR variables (p = 0.007). In C-statistics, native T1 of remote myocardium provided incremental prognostic information beyond clinical risk factors, LV ejection fraction, and other markers of infarct severity (all p < 0.05). The addition of remote zone native T1 to a model of prognostic CMR parameters (ejection fraction, infarct size, and myocardial salvage index) led to net reclassification improvement of 0.82 (95% confidence interval: 0.46 to 1.17; p < 0.001) and to an integrated discrimination improvement of 0.07 (95% confidence interval: 0.02 to 0.13; p = 0.01).Conclusions
In STEMI patients treated by PPCI, evaluation of remote zone alterations by quantitative noncontrast T1 mapping provided independent and incremental prognostic information in addition to clinical risk factors and traditional CMR outcome markers. Remote zone alterations may thus represent a novel therapeutic target and a useful parameter for optimized risk stratification.

Ingo Ludolph MD Raymund E. Horch MD Marina Harlander MD Andreas Arkudas MD Alexander D. Bach MD Ulrich Kneser MD Marweh Schmitz MD Christian D. Taeger MD Justus P. Beier MD 《The breast journal》2015,21(6):588-595
Autologous breast reconstruction with the deep inferior epigastric perforator (DIEP) or muscle‐sparing transverse rectus abdominis myocutaneous (ms‐TRAM) flap is a common method in the majority of patients after mastectomy. Because of an increased perioperative risk profile the benefit in older patients is questionable. To assess the postoperative quality of life and peri‐ and post‐operative complications of older compared to younger patients is the aim of this retrospective study. In a retrospective analysis 39 older (i.e. >60 years) and 140 younger patients (i.e. <60 years) with autologous breast reconstruction in the Department of Plastic Surgery at the University Hospital of Erlangen‐Nuernberg were surveyed at least 6 month postoperative using the BREAST‐Q questionnaire. Correlations were generated between comorbidities and complications. Significant differences were observed regarding hospitalization, pre‐existing diseases and the choice of DIEP versus ms‐TRAM flaps. Parameters such as major and minor complications, bulging or hernia and risk factors (e.g. smoking or obesity) showed no significant differences. The results of the questionnaire parameters showed no significant difference between both groups, revealing high satisfaction with the aesthetic result and an improvement in quality of life independent of age. Autologous breast reconstruction after mastectomy generates a gain in quality of life and shows a good to excellent overall satisfaction in older as well as younger patients. Despite a longer hospitalization and a different risk profile there were no significant differences regarding minor and major complications in the postoperative course. Hence autologous breast reconstruction for older patients is justified and should be taken into consideration. 相似文献

Direct and indirect biomarkers are widely applied for the determination of alcohol consumption. They help to assess past or present alcohol consumption. Depending on the window of detection and sensitivity of the investigated marker, punctual alcohol consumption may remain undetected. In this study, different sampling strategies for the intermediary long‐term marker phosphatidylethanol (PEth) are evaluated and compared to the determination of the short‐term markers ethyl glucuronide (EtG) and ethyl sulfate (EtS) in urine. Samples from 19 patients undergoing alcohol use disorder treatment were collected during the withdrawal treatment and successive rehabilitation (33 ± 26 days (range: 3–74 days)). With liquid chromatography–tandem mass spectrometry (LC–MS/MS) EtG and EtS in urine, PEth in blood, PEth in dried blood spot (DBS) from venous blood, and PEth in DBS from capillary blood were quantified and compared. The use of volumetric capillary DBS, prepared from 20 μL of blood, provided the same results as the use of venous DBS (95% ± 10%, R2 0.9899 for PEth 16:0/18:1). Capillary DBS sampling has the advantage that it can be performed without venipuncture. The use of PEth in DBS proved to prevent post‐sampling degradation, providing a longer detection in comparison to PEth in liquid blood, which only showed 67% ± 24% of the PEth DBS 16:0/18:1 concentration. When compared with EtG and EtS in urine, PEth monitoring proved to be advantageous for the detection of relapse situations, as the accumulation of PEth in blood prolongs the detectability. In conclusion, volumetric capillary DBS sampling for PEth is a simple and useful tool for compliance monitoring, and avoids hematocrit issues. 相似文献
