Aim: To identify maternal prenatal and postnatal smoking as risk factors for psychosocial behaviour problems in Swedish preschool children. Methods: This prospective, longitudinal population study compared mothers' self-reported smoking during pregnancy and when the child was 3 mo old with behaviour problems according to Achenbach's Child Behavior Checklist at 3 y ( 1428 children) and 5.5 y of age
There are several approaches to using nonstiff implicit linear multistep methods for solving certain classes of semi-explicit index 2 DAEs. Using β-blocked discretizations (Arevalo et al., 1996) Adams-Moulton methods up to order 4 and difference corrected BDF (Soderlind, 1989) methods up to order 7 can be stabilized. As no extra matrix computations are required, this approach is an alternative to
Early diagnosis of atherosclerosis is essential as many of the risk factors are life-style dependent. We suggest a new method to measure minute roughness of the size of micrometers of the arterial wall. The method was evaluated using three silicone phantoms sized 13 fun, 23 itm and 33 pm, respectively. The mean of the measured heights of the phantoms were 8.1 mu m (SD 0.0), 23.3 mu m (SD 0.2) and
A method for the in situ modification of hollow fiber membranes used as sampling units for microdialysis probes is presented. The method consists of adsorption-coating, high-molecular-weight poly(ethylene imine), PEI, onto membranes, already fitted on microdialysis probes. Modification of membranes was designed to specifically explore the so-called Andrade effects and thus enhance the interaction
Research findings suggest that in order to clarify the relationship between occupation and health, occupation needs to be framed in several different ways. One facet of occupation is satisfaction with daily occupations, assessed using the Satisfaction with Daily Occupations (SDO) instrument. The purpose was to investigate some of the SDO's psychometric properties when applied on people with persis
Neuroblastoma is a childhood tumor derived from precursor or immature cells of the sympathetic nervous system. Neuroblastomas show a tremendous clinical heterogeneity, encompassing truly benign as well as extremely aggressive forms. In vivo as well as in vitro data have shown that the degree of sympathetic neuronal tumor cell differentiation influences patient outcome. Unraveling mechanisms govern
This study addresses caring staff experiences of hindrances and help in the support of daily occupations among people with developmental disabilities. Data were collected by means of a questionnaire consisting of open-ended questions about the staff perceptions of their work experiences. The respondents (n = 81), corresponding to 94.1% of all care staff employed in a geographically defined care ar
Antibody response to Campylobacter jejuni/coli (CJC) was investigated, using an enzyme-linked immunosorbent assay, ELISA. With a mixture of lipopolysaccharide from two CJC strains as antigen in ELISA, all 24 tested rabbit anti-CJC sera showed high antibody levels. However, only 70% of sera from patients with Campylobacter enteritis demonstrated an antibody response against the combined LPS antigen
The clinical importance of asymptomatic proximal and distal deep vein thrombosis (DVT) remains uncertain and controversial. The aim of this retrospective, post-hoc analysis was to examine mortality and risk factors for development of proximal DVT in hospitalized patients with acute medical illness who were recruited into a randomized, prospective clinical trial of thromboprophylaxis with daltepari
Den övergripande målsättningen med projektet har varit att utifrån en prototyp av OE-staven ta fram ett fungerande mätsystem som håller jämförbar standard med dagens RF-mätningar. OE-metoden har visat sig uppfylla dessa krav och samtidigt vara ett kraftfullt verktyg för mätningar av RF-profiler i betongkonstruktioner. OE-metoden lämpar sig bäst att användas i svårbemästrade mätsituationer samt i s
A method for determining transition matrices for inhomogeneous dielectric shells is presented. The source can be either inside or outside the shell. The method is based upon expansions of the electric and magnetic fields in vector spherical harmonics. The expansion coefficients in the shell satisfy a system of linear ordinary differential equations in the radial direction. The expansion coefficien
Traditional 14C urea breath tests are normally not used for younger children because the radiation exposure is unknown. High sensitivity accelerator mass spectrometry and an ultra-low amount (440 Bq) of 14C urea were therefore used both to diagnose Helicobacter pylori (HP) infection in seven children, aged 3–6 years, and to make radiation dose estimates. The activity used was 125 times lower than
Animistic or 'relational' ontologies encountered in non-Western (i.e. premodern) settings pose a challenge to Western (i.e. modern) knowledge production, as they violate fundamentalassumptions of Cartesian science. Naturalscientists who have tried seriously to incorporate subject-subject relations into their intellectual practice (e.g. Uexküll, Bateson) have inexorably been relegated to the margin
