5心率恢复在心力衰竭患者中的预后预测价值显示文摘Background: The rate in which heart rate recovers from exercise has recently been shown to be a strong predictor of mortality in patients suspected of having coronary disease, but its prognostic value in patients with heart failure(HF) has not been explored. We sought to assess the prognostic utility of heart rate recovery(HRR) in patients with HF. Methods: Eighty-seven subjects diagnosed with compensated HF underwent cardiopulmonary exercise testing(CPX). Mean age and ejection fraction were 50.0(±13.9) years and 28.1%(±13.6%), respectively. Heart rate at 1-minute post-CPX was subtracted from maximal heart rate during the exercise test to produce a measure of HRR1 in beats per minute. Subjects were followed for a combined death/hospitalization end point for 1-year after CPX. Results: The mean peak respiratory exchange ratio, peak oxygen consumption(Vo2), minute ventilation/carbon dioxide production(VE/Vco2) slope, and HRR1 were 1.06(±0.11), 14.8(±4.7)mL·kg-1·min-1, 36.6(±8.6), and 11.0(±10.4) beat/min, respectively. Although all three variables were significant univariate predictors of the composite end point(P< .001), multivariate Cox regression analysis only retained the VE/Vco2 slope(χ2=33.5, P< .001) and HRR1(residual χArena R.

6Proto-Adamastor ocean crust(920 Ma)described in Brasiliano Orogen from coetaneous zircon and tourmaline显示文摘Proto-Adamastor ocean bathed Rodinia and successor continental fragments from 1.0-0.9 Ga up to0.75 Ga,and evolved into world Adamastor Ocean at 0.75-0.60 Ga.Mesoproterozoic oceanic crust is poorly preserved on continents,only indirect evidence registered in Brasiliano Orogen.We report first evidence of ophiolite originated in proto-Adamastor.We use multi-technique U-Pb-Hf zircon andδ^11B tourmaline isotopic and elemental compositions.The host tourmalinite is enclosed in metaserpentinite,both belonging to the Bossoroca ophiolite.Zircon is 920 Ma-old,εHf(920 Ma)=+12,HfTDM=1.0 Ga and has’oceanic’composition(e.g.,U/Yb<0.1).Tourmaline is dravite withδ^11B=+1.8‰(Tur 1),0‰(Tur 2),-8.5‰(Tur 3).These characteristics are a novel contribution to Rodinia and associated world ocean,because a fragment of proto-Adamastor oceanic crust and mantle evolved at the beginning of the Brasiliano Orogen.Léo A.Hartmann Mariana Werle Cassiana R.L.

8阿片制剂在胆囊切除术后发生疑似奥狄氏括约肌功能障碍中的作用被低估显示文摘Aims-Pain recurrence after cholecystectomy is often attributed to sphincter of Oddi dysfunction, whose diagnostic criteria and treatments remain uncertain. We performed a retrospective study to assess the possible precipitating role of opiate ingestion in this setting. Methods-The retrospective study of the files of 147 consecutive patients investigated for post-cholecystectomy syndrome by endoscopic ultrasonography and/or endoscopic retrograde cholangiography yielded 37 cases of suspected biliary-type sphincter of Oddi dysfunction. Results-Thirteen patients (30%) with suspected sphincter of Oddi dysfunction had taken opiate-containing drugs 15 minutes to two hours (median 1 hr) before the onset of pain (“Opiate group“). When compared with the 23 patients having not taken opiates (“Non Opiate Group“), they were significantly younger (47 vs. 60 yrs), had a narrower common bile duct (5.0 vs. 7.7 mm), but had similar biochemical abnormalities and belonged to the same Milwaukee’s classes, mainly class II. None of the patients in the “Opiate group“ were submitted to retrograde cholangiography or endoscopic sphincterotomy vs. 52%and 39%, respectively of the patients of the “Non-Opiate Group“. After a mean follow-up of 3.5 years, there were three recurrences of biliary-type pain (1 choledochal stone, and 2 suspected sphincter of Oddi dysfunction) in the “Opiate Group“, and 2 (1 choledochal stone, 1 after codeine intake) in the “Non-Opiate Group“. Conclusions-Opiate intake is a frequent cause of suspicion of sphincter of Oddi dysfunction after cholecystectomy, especially in young patients with a narrow common bile duct. A careful history taking is essential to avoid unnecessary and potentially harmful procedures.Druart-Blazy A. Pariente A. Berthelemy P. Arotarena R. 王晓君 2006世界核心医学期刊文摘(胃肠病学分册)2006,2,6:0
