Cuff inflation during ambulatory blood pressure monitoring and heart rate
Mia Skov-Madsen, My Svensson, Jeppe Hagstrup Christensen
Integrated Blood Pressure Control , 2008, DOI: http://dx.doi.org/10.2147/IBPC.S4072
Abstract: ff inflation during ambulatory blood pressure monitoring and heart rate Original Research (5574) Total Article Views Authors: Mia Skov-Madsen, My Svensson, Jeppe Hagstrup Christensen Published Date November 2008 Volume 2008:1 Pages 15 - 19 DOI: http://dx.doi.org/10.2147/IBPC.S4072 Mia Skov-Madsen, My Svensson, Jeppe Hagstrup Christensen Department of Nephrology, Aarhus University Hospital, Aalborg, Denmark Introduction: Twenty four-hour ambulatory blood pressure monitoring is a clinically validated procedure in evaluation of blood pressure (BP). We hypothesised that the discomfort during cuff inflation would increase the heart rate (HR) measured with 24-h ambulatory BP monitoring compared to a following HR measurement with a 24-h Holter monitor. Methods: The study population (n = 56) were recruited from the outpatient’s clinic at the Department of Nephrology, Aalborg Hospital, Aarhus University Hospital at Aalborg, Denmark. All the patients had chronic kidney disease (CKD). We compared HR measured with a 24-h Holter monitor with a following HR measured by a 24-h ambulatory BP monitoring. Results: We found a highly significant correlation between the HR measured with the Holter monitor and HR measured with 24-h ambulatory blood pressure monitoring (r = 0.77, p < 0.001). Using the Bland-Altman plot, the mean difference in HR was only 0.5 beat/min during 24 hours with acceptable limits of agreement for both high and low HR levels. Dividing the patients into groups according to betablocker treatment, body mass index, age, sex, angiotensin-converting enzyme inhibitor treatment, statins treatment, diuretic treatment, or calcium channel blocker treatment revealed similar results as described above. Conclusion: The results indicate that the discomfort induced by cuff inflation during 24-h ambulatory BP monitoring does not increase HR. Thus, 24-h ambulatory BP monitoring may be a reliable measurement of the BP among people with CKD.

Haptoglobin Genotype and Risk Markers of Cardiovascular Disease in Patients with Chronic Kidney Disease
Charlotte Strandhave,My Svensson,Henrik Krarup,Jeppe Hagstrup Christensen
International Journal of Nephrology , 2013, DOI: 10.1155/2013/650847
Abstract: Sudden cardiac death and atherosclerosis have a major impact on cardiovascular mortality in chronic kidney disease (CKD). Inflammation with elevated high-sensitive C-reactive protein (hs-CRP) is involved in both sudden cardiac death and atherosclerosis, and decreased heart rate variability (HRV) is a predictor of both sudden cardiac death and atherosclerosis. Haptoglobin (Hp) is characterised by three genotypes (1-1, 2-1, and 2-2) with different antioxidant abilities. The aim was to examine whether HRV and hs-CRP were associated with Hp genotype in CKD patients. Fifty-six patients with CKD stage 2–5 were included. Hp genotype was determined by high-performance liquid chromatography. HRV was analysed from the 24 h Holter recordings. Hs-CRP was measured using an immunoturbidimetric assay. The results show that the HRV indices SDNN and SDANN were significantly lower in the Hp 2-2 patients ( and 0.04, resp.). In an adjusted linear regression model, Hp 2-2 was associated with both SDNN ( ) and SDANN ( ). Hs-CRP was higher in the Hp 2-2 patients ( ). In an adjusted linear regression model, the association between Hp 2-2 and hs-CRP remained significant ( ). In conclusion, a negative association was observed between Hp 2-2 and HRV, and Hp 2-2 was positively associated with hs-CRP in CKD patients. 1. Introduction Cardiovascular disease (CVD) including sudden cardiac death (SCD) [1] is a major cause of mortality in chronic kidney disease (CKD) [2]. Apart from left ventricular dysfunction [1], unique factors such as autonomic imbalance and inflammation contribute to the high incidence of SCD in CKD [3]. Traditional risk factors for atherosclerosis [4], such as hypertension and dyslipidaemia, can to some extent explain the increased risk of atherosclerosis in CKD [5]. However, nontraditional risk factors like oxidative stress and inflammation may also be of importance [6]. Heart rate variability (HRV) is a reliable, noninvasive measurement of autonomic tone of the heart [7]. A reduction in HRV reflects an autonomic imbalance towards decreased vagal tone and subsequent sympathetic overactivity [3]. Decreased HRV is a predictor of SCD in patients with CKD [8]. Furthermore, attenuated HRV is associated with atherosclerosis in CKD [9]. Chronic, low-grade inflammation is involved in the development of both SCD [10] and atherosclerosis [11]. The most extensively examined marker of inflammation is high-sensitive C-reactive protein (hs-CRP), which is a predictor of cardiovascular mortality in different populations [12, 13] including patients with CKD [14]. Hs-CRP may even
The Concept of Oncoplastic Breast Surgery Applied in Surgery for a Giant Fibroadenoma  [PDF]
Michael Rose, Henry Svensson
Case Reports in Clinical Medicine (CRCM) , 2014, DOI: 10.4236/crcm.2014.34048
Abstract:

The treatment of a 40-year-old woman with a giant fibroadenoma in her left breast is presented. The fibroadenoma measured 14 × 5 × 3 cm and weighed 170 g. We demonstrate that the surgical strategy and the reconstructive techniques in oncoplastic breast cancer surgery successfully can be applied to the treatment of these rare benign tumours improving the cosmetic and functional outcome.

DarcyTools: A Computer Code for Hydrogeological Analysis of Nuclear Waste Repositories in Fractured Rock  [PDF]
Urban Svensson, Michel Ferry
Journal of Applied Mathematics and Physics (JAMP) , 2014, DOI: 10.4236/jamp.2014.26044
Abstract:

A computer code for simulation of groundwater flow and transport is described. Both porous and fractured media are handled by the code. The main intended application is the analysis of a deep repository for nuclear waste and for this reason flow and transport in a sparsely fractured rock is in focus. The mathematical and numerical models are described in some detail. In short, one may say that the code is based on the traditional conservation and state laws, but also embodies a number of submodels (subgrid processes, permafrost, etc). An unstructured Cartesian grid and a finite volume approach are the key elements in the discretization of the basic equations. A multigrid solver is part of the code as well as a parallelization option based on the SPMD (Single-Program Multiple-Data) method. The main application areas are summarized and an application to a deep repository is discussed in some more detail.

Analytical and Numerical Investigations of Probabilistic Monochromatic Problem  [PDF]
Stefan Schmuck, Jakob Svensson
Journal of Applied Mathematics and Physics (JAMP) , 2019, DOI: 10.4236/jamp.2019.74054
Abstract: A probabilistic formalism, relying on Bayes’ theorem and linear Gaussian inversion, is adapted, so that a monochromatic problem can be investigated. The formalism enables an objective test in probabilistic terms of the quantities and model concepts involved in the problem at hand. With this formalism, an amplitude (linear parameter), a frequency (non-linear parameter) and a hyperparameter of the Gaussian amplitude prior are inferred jointly given simulated data sets with Gaussian noise contributions. For the amplitude, an analytical normal posterior follows which is conditional on the frequency and the hyperparameter. The remaining posterior estimates the frequency with an uncertainty of MHz, while the convolution of a standard approach would achieve an uncertainty of some GHz. This improvement in the estimation is investigated analytically and numerically, revealing for instance the positive effect of a high signal-to-noise ratio and/or a large number of data points. As a fixed choice of the hyperparameter imposes certain results on the amplitude and frequency, this parameter is estimated and, thus, tested for plausibility as well. From abstract point of view, the model posterior is investigated as well.

In the course of research services protocol, a convenient and practical evaluation system will undoubtedly bring great help for the protocol, the paper design of mobile service evaluation system using a graphical way to display a variety of mobile services in the overhead data, system design a lightweight service protocol, and the protocol by the system for evaluation compared with a standard Web.
CONCIENCIA MORAL Y LIBERTAD DE CONCIENCIA EN LOCKE
Svensson,Manfred;
Ideas y Valores , 2011,
Abstract: locke is known for his place in the history of the liberty of conscience, but he is not known for any significant theory of moral conscience. this article aims at clarifying his views regarding both problems, and argues for the need to discuss both of these questions simultaneously, in order to avoid the trivialization of liberty of conscience.
Indiferencia, ambivalencia y tipos de consentimiento: Agustín en el Scito te Ipsum de Abelardo
Svensson, Manfred;
Kriterion: Revista de Filosofia , 2012, DOI: 10.1590/S0100-512X2012000100006
Abstract: augustine and abelard are frequently portrayed as representing mutually exclusive models of ethical theory: one centered in absolute moral norms, the other in intention. the present article stresses rather their agreement in these issues, while pointing to other differences between them: the kind of interior act each of them considers decisive, and the description of the external act as indifferent or ambivalent.
