Abstract 17588: Total Atrial Conduction Time Evaluated With Tissue Doppler Imaging Predicts Cardioembolic Stroke in Patients With Acute Ischemic Stroke
Authors: Gensai Yamaura, Tetsu Watanabe, Masahiro Wanezaki, Satoshi Nishiyama, Shintaro Sasaki, Isao Kubota
Journal: Circulation (2014)

Introduction:  Cardioembolic stroke has been increased with increasing the prevalence of atrial fibrillation (AF). However, AF cannot be detected in some patients with cardioembolic stroke. Total atrial conduction time is a marker of atrial remodeling and reflects the extent of both electrical and structural remodeling of the atria in contrast to atrial size. Recently, a novel echocardiographic parameter based on tissue Doppler imaging (TDI) has been used to assess the total atrial conduction time. The total atrial conduction time was estimated by measuring the time delay between the onset of the P-wave of electrocardiogram and peak A’-wave on the TDI of the left atrial lateral wall (PA-TDI duration).   Hypothesis:  We hypothesized that increased PA-TDI duration is a sensitive predictor for cardioembolic stroke.   Methods:  Transthoracic and transesophageal echocardiography were performed at discharge in 59 patients with sinus rhythm (41 males, mean age 69 ± 11 years) who were hospitalized for acute ischemic stroke.   Results:  There were 8 patients with cardioembolic stroke. Patients with cardioembolic stroke had higher log BNP, larger left atrial volume index and longer PA-TDI duration (138 ms vs. 119 ms) than those without cardioemboli stroke. Multivariate logistic regression analysis showed that PA-TDI duration was an independent predictor for cardioembolic stroke (odds ratio 3.227 (per 1SD increase), 95% confidence interval 1.156 - 12.228, P   Conclusions:  PA-TDI duration is a feasible predictor for cardioembolic stroke in patients with sinus rhythm and acute ischemic stroke.

How to Survive in Anaesthesia, by P Neville Robinson, George M Hall
Authors: S. Scothern, M. Shelly
Journal: BMJ (1997)

P Neville Robinson, George M Hall, BMJ Publishing Group, £19.95, pp 172 ISBN 0 7279 1066 3

The first questions asked by trainees starting out in anaesthesia are “What do I do …?” “How do I do …?” and “What if …?” They therefore need a book that contains basic information simply presented or a trainer with enormous patience. This book substantially reduces the need for a patient trainer. However, it is designed to complement the clinical training that the novice anaesthetist will be receiving and help the trainer to explain some of the concepts of anaesthesia.

The book answers many of the “What?” and “How?” questions, highlighting important information in tables and boxes. …

Experimental ModelsSimulation of human disease in laboratory animals is difficult when it is necessary to induce an intestinal infection lasting for several days. Infection can be produced by feeding of very large numbers of organisms, but a relevant clinical syndrome may not result. Starvation, opiates and streptomycin pretreatment have been used singly and in combination to compensate for the natural resistance of animals such as guinea pigs, rats and mice to challenge with salmonellae,120 shigellae24 and other organisms. Opiates are considered to be effective by retarding peristaltic excretion of organisms, and streptomycin is believed to suppress normal flora that . . .

Role of CEA, PLUNC and CK19 mRNA expression in lymph nodes from resected stage I non-small cell lung cancer (NSCLC) patients (p) as markers of occult micrometastasis. A pilot study

Journal: Journal of Clinical Oncology (2005)

9654 Background: 5-year survival for p with surgically resected stage IA-IB (NSCLC) is 70 and 38%. Recurrence of the disease is probably due to undetected systemic occult micrometastases (OM) at the time of initial diagnosis in the histopathologic analysis.The detection of OM would require a more sensitive and specific technique and would be of the greatest interest to define a high risk population and select p for postoperative adjuvant treatments. Objective: to assess the role of CEA, PLUNK and CK19 mRNA expression in pathological negative lymph nodes (LN) from resected stage I NSCLC p as markers of OM and correlate the results with relapse. Methods: paired tumour and histological negative LN (n=84) from 10 p were analyzed for the presence of CEA, CK19 and PLUNC mRNA expression using quantitative real-time PCR Q-PCR. RNA was extracted; GADPH was used as an endogenous control.Samples were also analyzed by immunohistochemistry for LN staging. Results: 10 NSCLC p;7 males;age range:47–77;5 adenoca, 3 squamous cell ca and 2 undiff tumours. CK19 and PLUNC were found to be expressed in tumour tissue of all p.CEA did not express in one of the squamous cell ca. tissues. In the 84 pathological negative LN, 23, 8% (20/84) were positive for CEA, 20%(17/84) for PLUNC,100%(84/84) for CK19 mRNA expression. Most LN positive for CEA were positive for PLUNC as well. The expression pattern were very similar for both markers in all 10 p analyzed.6/10 p showed positive lymph nodes and 4/10 were negatives.1/10 p relapsed after 11 mo of surgery and died after 18 mo. P had detectable levels of CEA and PLUNC mRNA in LN assessed by Q-PCR. The 9 p that did not relapse, 4 had no detectable LN expression levels of these markers and 5 had detectable LN expression levels (median follow-up of 12,5 mo; range 4–18 mo). Conclusions: CK19 has shown to be non specific tumoral marker since it were found to be expressed in all LN tested. But CEA and PLUNC have shown to be specific markers of OM.This fact could be of prognostic relevance and maybe a tool for select high-risk patients considered for adjuvant therapies.50 p are being assessed to corroborate this finding. Final data will be presented. No significant financial relationships to disclose.

10603 Background: BC in young women is associated with poor prognosis, which has been attributed to the higher incidence of aggressive BC subtypes. Whether the performance of prognostic gene expression signatures (GS) varies by BC subtype across age groups is unknown. Methods: We used publically available datasets and normalized microarray data as published by the original studies. Eligible patients were those with known age who received no adjuvant systemic therapy. Patients were assigned to 3 molecular subtypes (ER+, HER2+, ER-/HER2-). For each data set, we evaluated the following published signatures: Proliferation GS (GGI, GENE70, GENE76), stroma GS (DCN, SDPP, PLAU) and immune GS (IRM). We examined their interaction with age and relapse free survival in a Cox regression model. Improvements in their prognostic value over Adjuvant online! (AOL) were assessed by the change in the likelihood ratio value across different age groups (≤40, 41-60, >60). Results: 1254 patients (373 events) from 12 datasets were eligible; of whom 194 (15%) were ≤ 40 years. 64%, 15% and 21% had ER+, HER2+ and ER-/HER2- BC respectively. Younger (≤40) had significantly higher incidence of ER-/HER2- (29% vs. 20% vs. 18%) and HER2+ subtypes (21% vs. 15% vs. 9%) (p<0.0001). In ER+ group, there was no interaction between age and the prognostic performance of GS except for SDPP (p=0.03), which was not prognostic in patients >60. Adding proliferation GS to AOL significantly improved prognostication (overall effect, GGI: HR 2.9 [95% CI 2.2-3.9]; GENE70: 3.2 [2.2-4.5]; GENE76: 2.6 [2.1-3.3], all p<0.0001). However, in ER-/HER2-, only DCN and PLAU showed significant interaction with age (p=0.007 and 0.004). High DCN and PLAU levels were associated with poor prognosis only in patients ≤ 40 and improved prognostication when added to AOL (HR: 3.3 [1.1-9.4] and 3.0 [1.1-8.0]; all p=0.03). In ER-/HER2-, other GS did not add prognostic value to AOL in all age groups. Conclusions: Proliferation GS add significant prognostic information in ER+ BC irrespective of age. However, in ER-/HER2-, stroma GS added prognostic value only in patients ≤40. This data underscores the importance of understanding the tumor-stroma interactions especially in young BC patients.
