AIM To determine if end-stage renal disease (ESRD) is a risk factor for post endoscopic retrograde cholangio-pancreatography (ERCP) adverse events (AEs). METHODS We performed a retrospective cohort study using the Nationwide Inpatient Sample (NIS) 2011-2013. We identified adult patients who underwent ERCP using the International Classification of Diseases 9^(th) Revision (ICD-9-CM). Included patients were divided into three groups: ESRD, chronic kidney disease (CKD), and control. The primary outcome was post-ERCP AEs including pancreatitis, bleeding, and perforation determined based on specific ICD-9-CM codes. Secondary outcomes were length of hospital stay, in-hospital mortality, and admission cost. AEs and mortality were compared using multivariate logistic regression *** There were 492175 discharges that underwent ERCP during the 3 years. The ESRD and CKD groups contained 7347 and 39403 hospitalizations respectively, whereas the control group had 445424 hospitalizations. Post-ERCP pancreatitis (PEP) was significantly higher in the ESRD group (8.3%) compared to the control group (4.6%) with adjusted odd ratio (aOR) = 1.7 (95% CI: 1.4-2.1, ~aP gnificantly higher ERCP-related bleeding (5.1%) compared to the control group 1.5% (aOR = 1.86, 95%CI: 1.4-2.4, ~aP ger hospital stay with adjusted mean difference (aMD) = 5.9 d (95% CI: 5.0-6.7 d, ~aP gher hospitalization charges aMD = $+82064 (95%CI: $68221-$95906, ~aP gher hospital mortality. Careful selection and close monitoring is warranted to improve outcomes.

Cerebral Palsy and Stroke—Early and Late Brain Lesion Present Differences in Systemic Biomarkers and gene Expression Related to Muscle Contractures

g>Background:g> CNS lesions that are acquired early in life e.g. cerebral palsy (CP) disturb muscle development and growth, while CNS injuries acquired later in life e.g. stroke, affect fully matured muscles and cause paresis and atrophy. These differences may result in different contracture phenotypes. Aim: The purpose of this study was to compare systemic biomarkers and gene expression levels in muscle of individuals with CNS lesions acquired early and later in life. Methods: Blood samples and muscle biopsies were analyzed using Enzyme-linked immunosorbent assay and Real-time PCR from n = 24 control participants, n = 14 individuals with cerebral palsy, and n = 12 stroke survivors. Results: Systemic markers: Myostatin was significantly decreased in both the cerebral palsy (p = 0.0051), and the stroke group (p = 0.036). Creatine Kinase-MB and C-Reactive Protein were significantly elevated in stroke patients only (p 0.034 respectively). gene expressions: The expression of myostatin (MSTN) was significantly lower in both the ST and the CP group when compared to Ctrl (p = 0.02). In addition, collagen type 4A1 (COL4A1) was significantly lower in the CP group compared to the other groups (p = 0.015). Finally, the troponin 1 slow skeletal muscle type was significantly increased in the ST group when compared to both CP and Ctrl (p = 0.03). Conclusion: The downregulation of myostatin in individuals with both early and late CNS injury is likely a compensatory reaction to muscle weakness, reduced muscle mass and/or muscle atrophy. Changes in gene expression may reflect a specific alteration depending on when in life the CNS lesions were acquired.

趋磁细菌依靠其体内生物合成的磁小体颗粒沿地球磁场定向排列和游动,称为趋磁性。沿磁场的定向排列被认为可以使磁菌更有效地到达最佳生存环境,即趋磁性对磁菌的优势所在。目前对趋磁性优势的研究大多数集中在水环境或培养液环境下,而对于自然沉积物中趋磁性优势的理解还停留在假说阶段。越来越多的研究显示,磁菌在沉积物中的行为方式与水环境中所观测到的现象差别很大,因此,对趋磁性优势的研究也需要在沉积物环境中进行。本文我们通过对比在地磁场、近零磁场和反转磁场条件下两种磁菌:球菌和杆菌(Candidatus Magnetobacterium bavaricum)的时空变化,揭示在沉积物中趋磁性对趋磁细菌的作用。结果显示趋磁性对两种磁菌存在不同的作用,***在近零磁场条件下数量明显下降而在地磁场下又重新恢复,说明趋磁性优势对***的积极作用,然而球菌在近零磁磁场条件下的数量和分布与地磁场条件下相似,可能说明球菌在利用趋化性和行为方式上与***有很大不同。***在反转磁场条件下数量减少,而球菌则接近消失,说明球菌受极向趋磁性的影响比***大。两种磁菌因受沉积物环境和自身趋化性的影响在趋磁性上表现不同,可能***存在不同的趋磁性特点。本文实验结果说明对趋磁性的理解需要立足于复杂的沉积物环境。

欧洲已经计划在其沿岸大规模发展海上风力发电场。这就提出了有关对海洋环境的可能影响的重大问题。如果能够注意避开包含有稀有生境或物种的区域，那么施工期间的影响可能最大限度地减少到可忽略不计的程度。据我们现在所知，风力发动机运转期间，噪声、振动以及电磁场所造成的扰动，可认为对海洋环境的影响不大。礁体效应（即：增加一个硬底质）据信会对海洋环境造成不同尺度上的最大影响：小尺度影响，涉及材料、结构以及基底物质的不均匀性；中尺度影响：涉及护岸工程和防冲刷设施；大尺度影响：包括整个风力发电场的范围。本文联系从天然生境、人工礁以及海上其他人造构筑物所获得的研究结果探讨了这些不同尺度的影响。

Lifestyle after Cardiac Rehabilitation: Did the Message Come across, and Was It Feasible? An Analysis of Patients’ Narratives

引用

Health 2014年第19期6卷 2641-2650页

作者： Marie Veje Knudsen Sussie Laustsen Annemette Krintel petersen Sanne Angel Department of Physiotherapy and Occupational Therapy Aarhus University Hospital Aarhus Denmark Centre of Research in Rehabilitation (CORIR) Department of Clinical Medicine Aarhus University Hospital and Aarhus University Aarhus Denmark Department of Cardiothoracic and Vascular Surgery Aarhus University Hospital Aarhus Denmark Section of Nursing Department of Public Health Aarhus University Aarhus Denmark

Lifestyle following heart disease is considered important to prevent and reduce cardiovascular risk factors. Thus, cardiac rehabilitation is focused on potential lifestyle changes. Further insight into patients’ perspective on lifestyle after cardiac rehabilitation is needed as changing habits following heart disease is a complex matter. The objective of this study was to explore the characteristics of lifestyle after cardiac rehabilitation. A phenomenological-hermeneutic approach with qualitative interviews was performed in 20 patients six months after completing a hospital-based cardiac rehabilitation programme in 2012 at Aarhus University Hospital, Denmark. The patients were diagnosed with ischemic heart disease, heart failure or left heart valve disease. The interviews were analysed using the interpretation theory by Ricoeur. The variation in reactions to cardiac rehabilitation were: 1) considering prior lifestyle to be appropriate, maybe with minor adjustments;2) acknowledging the need for incorporating lifestyle changes;and 3) reconciling or feeling guilt when being unable to manage changes. Participation in the cardiac rehabilitation programme was a positive experience, but it had minor influence on long-term adherence to recommended lifestyle. The important thing in establishing new routines was whether they aroused interest, and whether the experience of changes was perceived as necessary and manageable. In future cardiac rehabilitation, focusing on patients’ interests and supporting them in incorporating recommendations into their everyday life might be essential following heart disease, also after ending cardiac rehabilitation.

随着各地污水厂出水水质对氮、磷要求的日益提高,强化脱氮除磷成为必然要求,但是我国多数污水厂由于多种原因导致进水碳源不足,尤其是进水SCOD、VFAs的匮乏,直接影响了生物脱氮除磷的效率,甚至不得已采用人工投加外碳源脱氮或者化学除磷方式以满足严格的出水氮、磷要求,但这无疑大大提高了污水厂的产泥率及运行成本。充分挖掘污水厂的"内碳源",利用污泥水解产生VFAs,不仅能有效提高除磷脱氮效率,而且可以降低污水厂的污泥产量,是可持续的资源化技术。比较了初沉污泥和活性污泥的水解特性差异,介绍了污泥水解工艺的常用构型及参数选择,以及国内外一些成功的实施案例。

Changes in Barents Sea ice Edge Positions in the Last 440 years: A Review of Possible Driving Forces

引用

International Journal of Astronomy and Astrophysics 2020年第2期10卷 97-164页

作者： Nils-Axel Mö rner Jan-Erik Solheim Ole Humlum Stig Falk-petersen Paleogeophysics & geodynamics Stockholm Sweden Department of Physics and Technology UiT The Arctic University of Norway Troms&oslash Norway The University Centre on Svalbard (UNIS) Longyearbyen Svalbard Norway The Fram Centre Akvaplan-niva Troms&oslash Norway

This is the first report of the Barents Sea Ice Edge (BIE) project. The BIE position has varied between latitude 76°N and above 82°N during the last 440 years. During the period 10,000 to 6000 years ago, Arctic climate was significantly warmer than today. We review various oceanic and atmospheric factors that may have an effect on the BIE position. The gulf Stream beat with respect to alternations in flow intensity and N-S distribution plays a central role for the changes in climate and BIE position during the last millennium. This occurred in combination with external forcing from total solar irradiation, Earth’s shielding strength, Earth’s geomagnetic field intensity, Earth’s rotation, jet stream changes;all factors of which are ultimately driven by the planetary beat on the Sun, the Earth and the Earth-Moon system. During the last 20 years, we see signs of changes and shifts that may signal the end of the late 20th century warm period. The BIE position is likely to start advancing southward in next decade.
