- To establish breastfeeding in preterm infants, test weighing before and after breastfeeding and gradual reduction of supplementation are both applicable regimens. Mothers can be encouraged to choose either of them, although test weighing may help infants attain exclusive breastfeeding at an earlier PMA.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of these studies was to increase knowledge about hospital feeding routines in high-risk neonates. A retrospective medical chart review procedure was used to study routines at the neonatal units of two Swedish hospitals. In Papers I and II, the sample (Uppsala n=21 and Umeå n=21) comprised of small for gestational age (SGA) infants, in Papers III (Uppsala n=64 and Umeå n=59) and IV (n=127), the samples comprised of appropriate for gestational age (AGA) infants. Paper I indicated large enteral/oral milk volumes rendered i.v. administration of glucose unnecessary, reduced weight loss and helped SGA infants regain birth weight earlier. More rapid postnatal growth did not remain up to 18 months with corrected age in any growth variable (Paper II). In Paper III, effects were compared whether the infants’ volume of breast milk intake in hospital was estimated by “clinical indices” or determined by test-weighing. Infants treated in hospitals where test-weighing was practised attained exclusive breastfeeding at an earlier postmenstrual age (PMA), and they were discharged at an earlier PMA. However, the two study units were similar regarding the proportion of infants attaining exclusive breastfeeding. Paper IV revealed preterm AGA infants with higher standard deviation scores (SDS) at birth had more negative changes from birth to discharge for all growth variables. Conclusions: Papers I and II indicated that early initiation of enteral/oral feeding with proactive increases in milk volume was beneficial short term. No evidence was found for a proactive nutrition regimen with initial large volumes of milk resulting in a different pattern of growth up to the corrected age of 18 months. Test-weighing before and after breastfeeding might help infants to attain exclusive breastfeeding at an earlier PMA (study III). Finally, preterm AGA infants with higher SDS at birth are at higher risk of inadequate growth during their hospital stay (study IV).

Tidskriftsartikel (refereegranskat)abstract
- Aim: The aim was to evaluate growth and breastfeeding up to 18 months corrected age (CA) among preterm appropriate for gestational age (AGA) infants whose mothers initiated breastfeeding during the infants' hospital stay. Methods: One hundred and twenty-seven preterm AGA infants with a median birth weight of 2320 (769-3250) g and gestational age 34.29 (25.00-35.86) weeks were evaluated up to a CA of 18 months. A retrospective, descriptive and comparative design was used. Data were obtained by chart review of hospital medical records and a questionnaire completed by the mothers. Results: The changes in standard deviation scores (SDS) during the infants' hospital stay were -0.9 for weight, -0.3 for length and -0.5 for head circumference (HC). Infants with higher SDS at birth showed more negative changes from birth to discharge. Median increments in SDS from discharge to a CA of 2 months were as high as, or higher than, the loss from birth to discharge. Conclusion: Preterm AGA infants with higher SDS for weight, length and HC at birth are at higher risk of inadequate growth during their hospital stay.

A High-Performance Tracking System based on Camera and IMU

Konferensbidrag (refereegranskat)abstract
- We consider an indoor tracking system consisting of an inertial measurement unit (IMU) and a camera that detects markers in the environment. There are many camera based tracking systems described in literature and available commercially, and a few of them also has support from IMU. These are based on the best-effort principle, where the performance varies depending on the situation. In contrast to this, we start with a specification of the system performance, and the design isbased on an information theoretic approach, where specific user scenarios are defined. Precise models for the camera and IMU are derived for a fusion filter, and the theoretical Cramér-Rao lower bound and the Kalman filter performance are evaluated. In this study, we focus on examining the camera quality versus the marker density needed to get at least a one mm and one degree accuracy in tracking performance.
