Too heavy, too late: investigating perinatal health outcomes in immigrants residing in Spain. A cross-sectional study (2009-2011).

Studies have shown that immigrants residing in Spain have lower risks of delivering low birthweight (LBW) and preterm babies despite their socioeconomic disadvantages (the healthy migrant paradox). However, less is known about other important perinatal outcomes derived from birth weight and gestational age such as macrosomia and post-term birth. This paper aims to compare the main indicators relat

A modified Lewis ECG lead system for ambulatory monitoring of atrial arrhythmias.

When using a reduced ECG lead system with three leads or less, the analysis of atrial activity during arrhythmias can become problematic due to low signal amplitude and noise. Long ago, Sir Thomas Lewis proposed a lead system for atrial activity enhancement in which two electrodes are placed directly on the chest, however, these leads are sensitive to arm movement artifacts. In this study, a modif

Topological effects on capsomer-polyion co-assembly

On the basis of a T = 1 icosahedral capsid model, the capsomer-polyion co-assembly process has been investigated by molecular dynamics simulations using capsomers with different net charge and charge distribution as well as linear, branched, and hyper-branched polyions. The assembly process was characterized in terms of the time-dependent cluster size probabilities, averaged cluster size, encapsul

Indirect Estimation of Semiparametric Binary Choice Models

One of the most cited studies within the field of binary choice models is that of Klein and Spady (1993), in which the authors propose a semiparametric estimator for use when the distribution of the error term is unknown. However, although theoretically appealing, the estimator has been found to be difficult to implement, and therefore not very attractive from an applied point of view. The current

Ions confined in spherical dielectric cavities modeled by a splitting field-theory.

The properties of ions confined within spherical dielectric cavities are examined by a splitting field-theory and Monte Carlo simulations. Three types of cavities are considered: one possessing a uniform surface charge density, one with a uniform volume charge density, and one containing mobile ions. In all cases, mobile counterions are present within the dielectric sphere. The splitting theory is

Mechanical compression during repeated sustained isometric muscle contractions and hyperemic recovery in healthy young males.

An elevated intramuscular pressure during a single forearm isometric muscle contraction may restrict muscle hyperemia. However, during repeated isometric exercise, it is unclear to what extent mechanical compression and muscle vasodilatation contribute to the magnitude and time course of beat-to-beat limb hemodynamics, due to alterations in leg vascular conductance (LVC).

Thermal Fluid-Structure-Interaction - Experimental and Numerical Analysis

In the present paper the thermal fluid-structure-interaction is experimentally and numerically investigated. Therefore, the interaction phenomena is modeled by the Reynolds-averaged Navier-Stokes equations and the nonlinear Fourier heat conduction equation are used for the fluid and the solid phase, respectively. The simulation is performed using a partitioned approach using the finite volume meth

How to image patients with spine pain.

Different radiological methods play an important role in the work-up of patients complaining of spine pain. Depending on the symptoms and the suspected underlying etiology different methods are selected. In the following presentation we briefly present the different radiological and magnetic resonance tomography methods that are at hand, give some guidance in which method to use, and present the t

Observations on extraction from V2 clauses in Scandinavian

Abstract in UndeterminedThis short communication presents a general overview of facts concerning wh-extraction from V2 clauses in the Scandinavian languages. While extraction from V2 clauses with a fronted non-subject is impossible in all of these languages, three classes can be distinguished with regard to extraction from subject-initial V2 clauses.

Perceptions of innovativeness among Iranian hotel managers

Despite the undisputed importance of organizational innovation and decades of academic research on the subject, there is surprisingly little agreement on what innovativeness is or how to achieve successful innovation in practice. Furthermore, the difference between the theory and practice is often interpreted in an ad hoc manner, which limits the potential for innovation to provide a competitive a

Inhibitors in haemophilia: what have we learned from registries? A systematic review.

Congenital haemophilia A and B are genetic disorders affecting factor VIII and factor IX production, respectively. Factor replacement is the only effective treatment for these deficiencies, but a patient's immune system can develop inhibitory antibodies which bind and interfere with the function of the replaced factor in a variety of ways. The main treatment goal for patients with inhibitors is to

Enhanced Insulin Sensitivity by Adipose Tissue Browning Alters Islet Morphology and Hormone Secretion in Response to Autonomic Nervous Activation in Female Mice.

Insulin resistance results in compensatory increase in insulin secretion to maintain normoglycemia. Conversely, high insulin sensitivity results in reduced insulin secretion to prevent hypoglycemia. The mechanisms for this inverse adaptation are not well understood. We utilized highly insulin sensitive mice, due to adipocyte specific overexpression of the FOXC2 transcription factor, to study mecha

Positron emission tomography in malignancies of the liver, pancreas and biliary tract - indications and potential pitfalls.

Abstract Malignancies of the hepato-pancreatico-biliary (HPB) system are relatively common and generally characterized by a dismal prognosis. Positron emission tomography (PET) is a functional imaging technique that has emerged as an important modality in oncological decision-making. The principal radiopharmaceutical in PET imaging is the glucose analog (18)F-fluorodeoxyglucose, which is able to d

Role of unphosphorylated transcription factor STAT3 in late cerebral ischemia after subarachnoid hemorrhage.

Molecular mechanisms behind increased cerebral vasospasm and local inflammation in late cerebral ischemia after subarachnoid hemorrhage (SAH) are poorly elucidated. Using system biology tools and experimental SAH models, we have identified signal transducer and activator of transcription 3 (STAT3) transcription factor as a possible major regulatory molecule. On the basis of the presence of transcr

Recovery after total intravenous general anaesthesia or spinal anaesthesia for total knee arthroplasty: a randomized trial.

BACKGROUND: /st>This study was undertaken to compare the effects of general anaesthesia (GA) and spinal anaesthesia (SA) on the need for postoperative hospitalization and early postoperative comfort in patients undergoing fast-track total knee arthroplasty (TKA). METHODS: /st>One hundred and twenty subjects were randomly allocated to receive either intrathecal bupivacaine (SA group) or GA with tar
