INTRODUCTION: Medical systems worldwide are facing the new threat of morbidity associated with the deliberate dispersal of microbiological agents by terrorists. Rapid diagnosis and containment of this type of unannounced attack is based on the knowledge and capabilities of medical staff. In 2004, the knowledge of emergency department physicians of anthrax was tested. The average test score was 58%. Consequently, a national project on bioterrorism preparedness was developed. The aim of this article is to present the project in which medical knowledge was enhanced regarding a variety of bioterrorist threats, including cutaneous and pulmonary anthrax, botulinum, and smallpox. METHODS: In 2005, military physicians and experts on bioterrorism conducted special seminars and lectures for the staff of the hospital emergency department and internal medicine wards. Later, emergency department senior physicians were drilled using one of the scenarios. RESULTS: Twenty-nine lectures and 29 drills were performed in 2005. The average drill score was 81.7%.The average score of physicians who attended the lecture was 86%, while those who did not attend the lectures averaged 78.3% (NS). CONCLUSIONS: Emergency department physicians were found to be highly knowledgeable in nearly all medical and logistical aspects of the response to different bioterrorist threats. Intensive and versatile preparedness modalities, such as lectures, drills, and posters, given to a carefully selected group of clinicians, can increase their knowledge, and hopefully improve their response to a bioterrorist attack. 相似文献

Since their establishment in 1981, RBL-2H3 cells have been widely used as a mast cell (MC) model. Their ability to be easily grown in culture in large amounts, their responsiveness to FcεRI-mediated triggers and the fact that they can be genetically manipulated, have provided advantages over primary MCs, in particular for molecular studies relying on genetic screening. Furthermore, the ability to generate clones that stably express proteins of interest, for example, a human receptor, have marked the RBL cells as an attractive MC model for drug screening. Indeed, 3 RBL reporter cell lines (RS-ATL8, NFAT-DsRed, and NPY-mRFP) have been generated providing useful models for drug and allergen screening. Similarly, RBL cells stably expressing the human MrgprX2 receptor provide a unique paradigm for analyzing ligand interactions and signaling pathways of the unique human receptor. Finally, transient co-transfections of RBL cells allow functional genomic analyses of MC secretion by combining library screening with simultaneous expression of a reporter for exocytosis. RBL cells thus comprise powerful tools for the study of intracellular membrane trafficking and exocytosis and the detection of allergens, vaccine safety studies and diagnosis of allergic sensitization. Their recent uses as an investigative tool are reviewed here. 相似文献

Limited studies have reported on outcomes for lymphoid malignancy patients receiving alternative donor allogeneic stem cell transplants. We have previously described combining CD34-selected haploidentical grafts with umbilical cord blood (haplo-cord) to accelerate neutrophil and platelet engraftment. Here, we examine the outcome of patients with lymphoid malignancies undergoing haplo-cord transplantation at the University of Chicago and Weill Cornell Medical College. We analyzed 42 lymphoma and chronic lymphoblastic leukemia (CLL) patients who underwent haplo-cord allogeneic stem cell transplantation. Patients underwent transplant for Hodgkin lymphoma (n?=?9, 21%), CLL (n?=?5, 12%) and non-Hodgkin lymphomas (n?=?28, 67%), including 13 T cell lymphomas. Twenty-four patients (52%) had 3 or more lines of therapies. Six (14%) and 1 (2%) patients had prior autologous and allogeneic stem cell transplant, respectively. At the time of transplant 12 patients (29%) were in complete remission, 18 had chemotherapy-sensitive disease, and 12 patients had chemotherapy-resistant disease. Seven (17%), 11 (26%), and 24 (57%) patients had low, intermediate, and high disease risk index before transplant. Comorbidity index was evenly distributed among 3 groups, with 13 (31%), 14 (33%), and 15 (36%) patients scoring 0, 1 to 2, and ≥3. Median age for the cohort was 49 years (range, 23 to 71). All patients received fludarabine/melphalan/antithymocyte globulin conditioning regimen and post-transplant graft-versus-host disease (GVHD) prophylaxis with tacrolimus and mycophenolate mofetil. The median time to neutrophil engraftment was 11 days (range, 9 to 60) and to platelet engraftment 19.5 days (range, 11 to 88). Cumulative incidence of nonrelapse mortality was 11.6% at 100 days and 19 % at one year. Cumulative incidence of relapse was 9.3% at 100 days and 19% at one year. With a median follow-up of survivors of 42 months, the 3-year rates of GVHD relapse free survival, progression-free survival, and overall survival were 53%, 62%, and 65%, respectively, for these patients. Only 8% of the survivors had chronic GVHD. In conclusion, haplo-cord transplantation offers a transplant alternative for patients with recurrent or refractory lymphoid malignancies who lack matching donors. Both neutrophil and platelet count recovery is rapid, nonrelapse mortality is limited, excellent disease control can be achieved, and the incidence of chronic GVHD is limited. Thus, haplo-cord achieves high rates of engraftment and encouraging results. 相似文献

There is currently no international consensus procedure for performing comprehensive periictal testing of patients in the epilepsy monitoring units (EMUs). Our primary goal was to develop a standardized procedure for managing and testing patients during and after seizures in EMUs. The secondary goal was to assess whether it could be implemented in clinical practice (feasibility). A taskforce was appointed by the International League Against Epilepsy (ILAE)—Commission on European Affairs and the European Epilepsy Monitoring Unit Association, to develop a standardized ictal testing battery (ITB) based on expert opinion and experience with various local testing protocols. ITB contains a comprehensive set of 10 items that evidence the clinically relevant semiologic features, and it is adaptive to the dynamics of the individual seizures. The feasibility of the ITB was prospectively evaluated on 250 seizures from 152 consecutive patients in 10 centers. ITB was successfully implemented in clinical practice in all 10 participating centers and was considered feasible in 93% of the tested seizures. ITB was not feasible for testing seizures of very short duration. 相似文献

Background
Few previous studies have assessed the safety of bariatric surgery in septuagenarians.Methods
A retrospective analysis of all patients 70 years or older who underwent laparoscopic sleeve gastrectomy at our institution between 2012 and 2017 was performed. This group was compared to a matched cohort of younger LSG patients (18–50 years) who were operated during the same time period.Results
Thirty septuagenarian LSG patients were compared to 60 younger patients. Gender distribution, preoperative weight, and preoperative body mass index (BMI) were comparable, although patients in the older age group suffered from more preoperative comorbidities (100 vs. 51.7%, p?<?0.001). Operative time was longer (77.2 vs. 57.3 min, p?=?0.005) and more hiatal hernias were repaired (46.7 vs. 8.3%, p?<?0.001) in the older age group. Intraoperative complications occurred more in the older age group (6.7 vs. 0%, p?=?0.04) but the overall complication rate (13.3 vs. 5.0%, p?=?0.17) and the postoperative complication rate (10.0 vs. 5.0%, p?=?0.38) were comparable. After a mean follow-up period of 31.3 and 33.5 months, the percentage of total body weight loss was 24.6 and 28.3% for the older and younger patients, respectively (p?=?0.11). Rates of improvement/remission of comorbidities were comparable between the groups.Conclusions
In a carefully selected group of severely obese patients ≥?70 years old, LSG may be safe, with acceptable postoperative complication rates, weight loss results, and improvement in comorbidities.117.

Mast cells are (in)famous for their role in allergic diseases, but the physiological and pathophysiological roles of this ingenious cell are still not fully understood. Mast cells are important for homeostasis and surveillance of the human system, recognizing both endogenous and exogenous agents, which induce release of a variety of mediators acting on both immune and non-immune cells, including nerve cells, fibroblasts, endothelial cells, smooth muscle cells, and epithelial cells. During recent years, clinical and experimental studies on human mast cells, as well as experiments using animal models, have resulted in many discoveries that help decipher the function of mast cells in health and disease. In this review, we focus particularly on new insights into mast cell biology, with a focus on mast cell development, recruitment, heterogeneity, and reactivity. We also highlight the development in our understanding of mast cell-driven diseases and discuss the development of novel strategies to treat such conditions. 相似文献

Carbapenems are considered the treatment of choice for Acinetobacter baumannii infections. Many facilities implement preventive measures toward only carbapenem-resistant A. baumannii (CRAB). However, the independent role of the carbapenem resistance determinant on patient outcomes remains controversial. In a 6-year analysis of adults with A. baumannii bloodstream infection (BSI), the outcomes of 149 CRAB isolates were compared to those of 91 patients with carbapenem-susceptible A. baumannii. In bivariable analyses, CRAB BSIs were significantly associated with worse outcomes and with a delay in the initiation of appropriate antimicrobial therapy (DAAT). However, in multivariable analyses, carbapenem resistance status was no longer associated with poor outcomes, while DAAT remained an independent predictor. The epidemiological significance of A. baumannii should not be determined by its resistance to carbapenems. 相似文献

β-Lactam-aminoglycoside combinations are commonly used despite lack of evidence of a clinical benefit. In this study, all randomised controlled trials (RCTs) assessing directly the clinical implications of synergism by comparing a β-lactam with the same β-lactam in combination with an aminoglycoside as empirical or definitive therapy for any type of infection and clinical scenario were compiled. A systematic search was undertaken to identify all trials regardless of language, date or publication status. The primary outcomes assessed were all-cause mortality and clinical failure regardless of antibiotic modifications. Risk of bias was evaluated and its effect was assessed through sensitivity analyses. Two reviewers applied inclusion criteria and extracted the data independently. A fixed-effect meta-analysis was performed. Fifty-two RCTs were identified assessing patients with febrile neutropenia, pneumonia, abdominal infections, bacteraemia, endocarditis or cystic fibrosis. Only five trials were double-blinded. All-cause mortality was similar with monotherapy versus combination therapy [risk ratio (RR)=0.96, 95% confidence interval (CI) 0.78-1.18, 28 trials, 3756 episodes]. Clinical failure regardless of antibiotic modifications was not significantly different (RR=0.88, 95% CI 0.74-1.05, 27 trials, 2500 episodes). Treatment failure including antibiotic addition/modification occurred more frequently with monotherapy (RR=1.20, 95% CI 1.12-1.28, 48 trials, 6643 episodes). There were no significant differences with regard to bacterial or fungal superinfections or development of antibiotic-resistant strains. Combination therapy resulted in a significantly higher incidence of adverse events, mainly nephrotoxicity. Overall, no clinical benefit was found for the use of a β-lactam with an aminoglycoside compared with a β-lactam alone. Treatment with β-lactams as monotherapy entailed more antibiotic regimen modifications in open trials. 相似文献
