- Using a fluid-filled wire with a pressure sensor outside the patient compared to a conventional pressure wire may avoid the systematic error introduced by the hydrostatic pressure within the coronary circulation.To assess the safety and effectiveness of the novel fluid-filled wire, Wirecath (Cavis Technologies, Uppsala, Sweden), as well as its ability to avoid the hydrostatic pressure error.The Wirecath pressure wire was used in 45 eligible patients who underwent invasive coronary angiography and had a clinical indication for invasive coronary pressure measurement at Sahlgrenska University Hospital, Gothenburg, Sweden. In 29 patients, a simultaneous measurement was performed with a conventional coronary pressure wire (PressureWire X, Abbott Medical, Plymouth, MN, USA), and in 19 patients, the vertical height difference between the tip of the guide catheter and the wire measure point was measured in a 90-degree lateral angiographic projection. No adverse events caused by the pressure wires were reported. The mean Pd/Pa and mean FFR using the fluid-filled wire and the sensor-tipped wire differed significantly; however, after correcting for the hydrostatic effect, the sensor-tipped wire pressure correlated well with the fluid-filled wire pressure (R=0.74 vs. R=0.89 at rest and R=0.89 vs. R=0.98 at hyperemia).Hydrostatic errors in physiologic measurements can be avoided by using the fluid-filled Wirecath wire, which was safe to use in the present study. This trial is registered with NCT04776577 and NCT04802681.

- The 20-item Toronto Alexithymia Scale (TAS) was completed at the age of 22 years by individuals who had previously suffered from anorexia nervosa (AN), and also by members of a comparison group. The AN and comparison groups had been recruited from community samples. Overall, the TAS scores did not clearly discriminate between the two groups. However, the AN group was significantly more often represented among subjects with the highest TAS scores. A subgroup with empathy disorder tended to have particularly high scores. It is concluded that alexithymia, as defined using the TAS-20, is found only in a subgroup of individuals with AN, and possibly more often in those who are also clinically diagnosed as suffering from empathy disorder. The TAS-20 is not suitable for screening of AN in the general population.

- Abnormal eating behaviors are overrepresented in the autism spectrum disorders, including food refusal, pica, rumination, and selective eating. Those disturbances can have detrimental complications and are often resistant to treatment. In autism spectrum disorders the background factors to eating disturbances are more complex than in the general child population, and sensory abnormalities, ritualistic behaviors, and social communication problems all seem to contribute. The eating problems in autism spectrum disorders may increase the risk for developing clinically significant eating disorders such as anorexia nervosa. Autistic traits must be considered in the treatment of the eating disorders and seem to be predictors for a poor psychosocial outcome after recovery from the eating disorder per se.

- Aim. To establish the prevalence of restrictive eating problems, the overlap and association with attention-deficit/hyperactivity disorder (ADHD), and autism spectrum disorders (ASD) and to estimate the heritability of eating problems in a general population sample of twins aged 9 and 12. Methods. Parents of all Swedish 9- and 12-year-old twin pairs born between 1993 and 1998 (n = 12,366) were interviewed regarding symptoms of ADHD, ASD, and eating problems (EAT-P). Intraclass correlations and structural equation modelling were used for evaluating the influence of genetic and environmental factors. Cross-twin, cross-trait correlations were used to indicate a possible overlap between conditions. Results. The prevalence of eating problems was 0.6% in the study population and was significantly higher in children with ADHD and/or ASD. Among children with eating problems, 40% were screened positive for ADHD and/or ASD. Social interaction problems were strongly associated with EAT-P in girls, and impulsivity and activity problems with EAT-P in boys. The cross-twin, cross-trait correlations suggested low correlations between EAT-P and ADHD or EAT-P and ASD. Genetic effects accounted for 44% of the variation in liability for eating problems. Conclusions. In the group with eating problems, there was a clear overrepresentation of individuals with ADHD and/or ASD symptoms.

Outcome of teenage-onset anorexia nervosa in a Swedish community-based sample

Tidskriftsartikel (refereegranskat)abstract
- In a prospective long-term outcome study of a representative sample of teenage-onset anorexia nervosa (AN), 51 individuals with AN, recruited after community screening, were contrasted with 51 matched comparison cases at a mean age of 24 years (10 years after AN onset). All 102 cases had been examined at age 16 and 21 years. At 24 years all probands were interviewed regarding mental and physical health, and overall outcome was assessed. Ten-year outcome of teenage-onset AN seemed to be relatively favourable in that half of all cases were free from eating disorder (ED) and other axis I disorder. There were no deaths. However, one in four in the AN group had a persisting ED, 3 of whom still had AN. Lifetime diagnoses of affective disorders and obsessive-compulsive disorder (OCD) were overrepresented in the AN group. Affective disorders coincided with the ED, and were not a problem after recovery from the ED. On the other hand, OCD, OCPD (obsessive-compulsive personality disorder), and/or autism spectrum disorder continued to characterise more than one-third of the AN cases. One in six of the AN group had persistent problems with social interaction and obsessive compulsive behaviours from childhood into early adult years. Half the AN group had a poor overall outcome. These were subjects with either persisting ED or lifelong problems with social interaction and obsessive compulsive behaviour.

Regional cerebral blood flow in weight-restored anorexia nervosa: a preliminary study.

Tidskriftsartikel (refereegranskat)abstract
- Twenty-one individuals (19 females, two males) with teenage-onset anorexia nervosa (AN), 19 of whom were weight restored, were assessed using single-photon emission computed tomography (SPECT) 7 years after onset of AN, at a mean age of 22 years. For comparison we recruited a younger group without neuropsychiatric disorder (mean age 9:8 years; five females, four males) who underwent SPECT at follow-up after an operation for coarctation of the aorta or because of lymphatic leukaemia. Ethical considerations precluded the study of regional cerebral blood flow (rCBF) in participants with completely normal development. The group with AN showed marked hypoperfusion of temporal, parietal, occipital, and orbitofrontal lobes compared to the contrast group. rCBF was not correlated to body mass index in any of the groups. Results suggest that, even long after re-feeding has occurred, AN may be associated with moderate to severe cerebral blood flow hypoperfusion in the temporoparietal (or temporoparietooccipital) region and in the orbitofrontal region. A limitation of the study is that the young contrast group in this study could be expected to have a higher global rCBF than the group with AN. However, this should not significantly affect the relative values used in this study.

Is It Possible to Foster Long-Term Construction-Site Safety Leadership Through Behavioural Training?
- 2023

- Despite the increasing popularity of organisational leadership training, context- specific longer-term training transfer remains under-researched. We examine how two safety-leadership behaviours - giving performance feedback and listening actively -were retained, applied, and transferred from the learning context to the construction- site workplace. Four to five months after the completion of a nine-week individualised behaviour-based safety-leadership training (IBST), carried out in Sweden, open-ended life-story, 90-minute interviews were carried out with seven site- manager participants and their respective seven foreman/woman. The findings suggest that long-term safety-leadership behaviours may be transferred to the workplace; however, contextual contingencies and exigencies, for example, participant characteristics and situated work-environment, proved of crucial importance for training transfer. To achieve effective safety-leadership training transfer that reinforces safe behaviour on construction sites, it would be wise to problematise the dynamics of participant motivations and situated construction- project factors.
