The successful management of a Bronchoesophageal fistula after lung transplantation: a case report 下载免费PDF全文
Stefania Camagni Alessandro Lucianetti Paolo Ravelli Giovanni B. Di Dedda Ezio Bonanomi Vittorio Corno Alessandro Aluffi Domenico Pinelli Marco F. Zambelli Michela Guizzetti Piercarlo Parigi Michele Colledan 《Transplant international》2015,28(7):884-887
We describe an unprecedented, disastrous complication after bilateral lung transplantation (BLT), a bilateral bronchial dehiscence with a right bronchoesophageal fistula leading to life‐threatening septic shock. We also report the successful endoscopic management of this complication by double stenting and stress the efficacy of the multidisciplinary approach to this critical case. 相似文献

This study explored the effect of lateralized left–right resting brain activity on prefrontal cortical responsiveness to emotional cues and on the explicit appraisal (stimulus evaluation) of emotions based on their valence. Indeed subjective responses to different emotional stimuli should be predicted by brain resting activity and should be lateralized and valence-related (positive vs negative valence). A hemodynamic measure was considered (functional near-infrared spectroscopy). Indeed hemodynamic resting activity and brain response to emotional cues were registered when subjects (N = 19) viewed emotional positive vs negative stimuli (IAPS). Lateralized index response during resting state, LI (lateralized index) during emotional processing and self-assessment manikin rating were considered. Regression analysis showed the significant predictive effect of resting activity (more left or right lateralized) on both brain response and appraisal of emotional cues based on stimuli valence. Moreover, significant effects were found as a function of valence (more right response to negative stimuli; more left response to positive stimuli) during emotion processing. Therefore, resting state may be considered a predictive marker of the successive cortical responsiveness to emotions. The significance of resting condition for emotional behavior was discussed. 相似文献

Starfish can regenerate entire arms following their loss by both autotomic and traumatic amputation. Although the overall regenerative process has been studied several times in different asteroid species, there is still a considerable gap of knowledge as far as the detailed aspects of the repair phase at tissue and cellular level are concerned, particularly in post‐traumatic regeneration. The present work is focused on the arm regeneration model in the Mediterranean red starfish Echinaster sepositus; to describe the early cellular mechanisms of arm regeneration following traumatic amputation, different microscopy techniques were employed. In E. sepositus, the repair phase was characterized by prompt wound healing by a syncytial network of phagocytes and re‐epithelialisation followed by a localized subepidermal oedematous area formation. Scattered and apparently undifferentiated cells, intermixed with numerous phagocytes, were frequently found in the wound area during these first stages of regeneration and extensive dedifferentiation phenomena were seen at the level of the stump, particularly in the muscle bundles. A true localized blastema did not form. Our results confirm that regeneration in asteroids mainly relies on morphallactic processes, consisting in extensive rearrangement of the existing tissues which contribute to the new tissues through cell dedifferentiation, redifferentiation, and/or migration. 相似文献

Background
Pathological Q waves (QWs) in the first ECG recorded at hospital admission has been found to correlate with myocardial damage and mortality in STEMI patients. We investigated the association between new QWs recorded in the pre-hospital setting and adverse outcome during the hospital stay.Methods
A pre-hospital ECG was recorded in 248 patients with STEMI who underwent primary PCI. Patients were divided into two groups based on the presence (n?=?44, QWs) or absence (n?=?204, non-QWs) of new QWs.Results
Patients with new QWs had a higher prevalence of anterior infarct, cardiogenic shock and a lower LV ejection fraction. In-hospital mortality was higher in patients with new QWs. The percentage of patients with new QWs increased progressively with increasing pain to ECG time.Conclusions
New QWs provide rapid prognostic information in the pre-hospital phase of STEMI by identifying patients at risk of adverse outcome during the hospital stay. 相似文献79.

XLP1 inhibitory effect by 2B4 does not affect DNAM‐1 and NKG2D activating pathways in NK cells 下载免费PDF全文
Raffaella Meazza Claudia Tuberosa Valentina Cetica Michela Falco Fabrizio Loiacono Silvia Parolini Concetta Micalizzi Alessandro Moretta Maria C. Mingari Lorenzo Moretta Cristina Bottino Maurizio Aricò Daniela Pende 《European journal of immunology》2014,44(5):1526-1534
X‐linked lymphoproliferative disease 1 (XLP1) is a rare congenital immunodeficiency caused by SH2D1A (Xq25) mutations resulting in lack or dysfunction of SLAM‐associated protein adaptor molecule. In XLP1 patients, upon ligand (CD48) engagement, 2B4 delivers inhibitory signals that impair the cytolytic activity of NK (and T) cells. This causes the selective inability to control EBV infections and the occurrence of B‐cell lymphomas. Here, we show that in the absence of SLAM‐associated protein, co‐engagement of 2B4 with different activating receptors, either by antibodies or specific ligands on target cells, inhibits different ITAM‐dependent signaling pathways including activating killer Ig‐like receptors. In XLP1 NK cells, 2B4 affected both the cytolytic and IFN‐γ production capabilities, functions that were restored upon disruption of the 2B4/CD48 interactions. Notably, we provide evidence that 2B4 dysfunction does not affect the activity of DNAM‐1 and NKG2D triggering receptors. Thus, while CD48+ B‐EBV and lymphoma B cells devoid of NKG2D and DNAM‐1 ligands were resistant to lysis, the preferential usage of these receptors allowed XLP1 NK cells to kill lymphomas that expressed sufficient amounts of the specific ligands. The study sheds new light on the XLP1 immunological defect and on the cross‐talk of inhibitory 2B4 with triggering NK (and T) receptors. 相似文献
