AIM: To assess the prevalence of bowel dysfunction in hemiplegic patients, and its relationship with the site of neurological lesion, physical immobilization and pharmacotherapy. METHODS: Ninety consecutive hemiplegic patients and 81 consecutive orthopedic patients were investigated during physical motor rehabilitation in the same period, in the same center and on the same diet. All subjects were interviewed ≥ 3 mo after injury using a questionnaire inquiring about bowel habits before injury and at the time of the interview. Patients’ mobility was evaluated by the Adapted Patient Evaluation Conference System. Drugs considered for the analysis were nitrates, angiogenic converting enzyme (ACE) inhibitors, calcium antagonists, anticoagulants, antithrombotics, antidepressants, anti-epileptics. RESulTS: Mobility scores were similar in the two groups. De novo constipation (OR = 5.36) was a frequent outcome of the neurological accident. Hemiplegics showed an increased risk of straining at stool (OR: 4.33), reduced call to evacuate (OR: 4.13), sensation of incomplete evacuation (OR: 3.69), use of laxatives (OR: 3.75). logistic regression model showed that constipation was significantly and independently associated with hemiplegia. A positive association was found between constipation and use of nitrates and antithrombotics in both groups. Constipation was not related to the site of brain injury. CONCluSION: Chronic constipation is a possible outcome of cerebrovascular accidents occurring in 30% of neurologically stabilized hemiplegic patients. Its onset after a cerebrovascular accident appears to be independent from the injured brain hemisphere, and unrelated to physical inactivity. Pharmacological treatment with nitrates and antithrombotics may represent an independent risk factor for developing chronic constipation.

Risk of New-Onset Atrial Fibrillation in Elderly Patients with the Overlap Syndrome: A Retrospective Cohort Study

引用

Journal of Geriatric Cardiology 2013年第2期10卷 129-134页

作者： Harsha V. Ganga Sanjeev u. Nair Venkata K. Puppala Wayne l. Miller The Henry low Heart Center Hartford Hospital B-1010 80 Seymour Street Hartford CT 06102 USA St. Joseph's Hospital 45 W 10th St St. Paul MN 55102 USA Division of Cardiovascular Diseases Mayo Clinic Rochester MN 55905 USA

Background Co-existence of obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) is referred to as overlap syndrome. Overlap patients have greater degree of hypoxia and pulmonary hypertension than patients with OSA or COPD alone. Studies showed that elderly patients with OSA alone do not have increased risk of atrial fibrillation (AF) but it is not known if overlap patients have higher risk of AF. Objective To determine whether elderly patients with overlap syndrome have an increased risk of AF. Methods In this single center, community-based retrospective cohort analysis, data were collected on 2,873 patients > 65 years of age without AF, presenting in the year 2006. Patients were divided into OSA group (n = 60), COPD group (n = 416), overlap syndrome group (n = 28) and group with no OSA or COPD(n = 2369). The primary endpoint was incidence of new-onset AF over the following two years. logistic regression was performed to adjust for heart failure (HF), coronary artery disease, hypertension (HTN), cerebrovascular disease, cardiac valve disorders, diabetes mellitus, hyperlipidemia, chronic kidney disease (CKD) and obesity. Results The incidence of AF was 10% in COPD group, 6% in OSA group and 21% in overlap syndrome group (P usting for age, sex, HF, CKD, and HTN, patientswith overlap syndrome demonstrated a significant association with new-onset AF (OR = 3.66, P = 0.007). HF, CKD and HTNwere also significantly associated with new-onset AF (P lusion Among elderly patients, the presence of overlap syndrome is associatedwith a marked increase in risk of new-onset AF as compared to the presence of OSA or COPDalone.

利用背景噪声方法,对布设在华南块体及其周边区域数个流动地震台阵中共704个地震台站的连续数据进行分析,反演得到华南岩石圈的三维S波速度结构。结果表明,地表附近S波速度结构与华南块体的地表构造高度相关,低速异常区集中在四川盆地和江汉盆地等沉积层较厚的区域。江南造山带的中上地壳呈现明显的高速异常,该高速异常即为华夏块体与扬子块体的分界区域。华夏块体中地壳低速异常区与该区域广泛分布的中生代花岗岩对应较好。华南上地幔岩石圈的东部与西部存在显著的速度差异,西部呈现显著的高速异常,反映西部四川盆地底部稳固的克拉通结构;上地幔的低速异常揭示华南东部岩石圈因太平洋板块俯冲的影响而明显减薄(<70km)。推测华夏块体以琼州海峡为中心的上地幔显著低速区可能对应海南地幔柱的热物质上涌。

In this study,the authors focus on the cut-off low pressure systems（COls）lingering over East Asia in late spring and early summer and quantify the two-way stratosphere–troposphere exchange（STE）by 3D trajectory integrations,achieved using a revised version of the uK universities Global Atmospheric Modelling Programme Offline Trajectory Code（Version 3）.By selecting 10 typical COls and cal.ulating the cross-tropopause air mass fluxes,it is found that stratosphere-to-troposphere transport（STT）fluxes exist in the center of COls;and in the periphery of the COl center,troposphereto-stratosphere transport（TST）fluxes and STT fluxes are distributed *** transport fluxes in COls are from stratosphere to troposphere,and the magnitude is about 10-4 kg m-2 *** ratio between the area-averaged STT and TST fluxes increases with increasing strength of the *** adopting appropriate residence time,the spurious transports are effectively ***,the authors compare the results with previous studies,and find that the cross-tropopause fluxes（CTFs）induced by COls are about one to two orders of magnitude larger than global *** play a significant role in local,rapid air mass exchanges,although they may only be responsible for a fraction of the total STE.

地质勘探类型是科学地质调查和有效矿产资源评价的基础和前提。矿田是包含几个矿床的成矿空间,单个矿床的勘探类型不一定适用于矿田的地质勘探。文中遵循"成矿作用、地质工作程度和资源经济条件"的思路,探讨矿田勘探类型和分类问题。以地质勘查工作程度(地质调查或勘探报告所遵循的工作精度,即成果图件的比例尺为指标)和资源技术经济条件(各级资源储量的比例,并结合矿山生产规模为指标)为指标,作者建立"地质勘查程度资源经济条件"评价系统。经该系统的综合评价,研究预查矿田(Ⅲ)、普查矿田(Ⅱ)和详查矿田(Ⅰ)的基本地质勘探类型。矿田地质勘探类型的确定,为推动整装勘查区的找矿突破、制定勘查规划和勘探工作的投入提供了可参考的方法和思路。文中选择6个典型矿田,详细展示矿田勘探类型的评价过程和方法。
