- BACKGROUND: Parental socioeconomic status (SES) is an important determinant in child health, influencing beneficial factors such as breastfeeding. A better understanding of the influence of neighbourhood-level SES measures, relating to spatial determinants, might lead to targeted actions to promote breastfeeding during infancy.METHODS: A cross-sectional study analysis the association between breastfeeding at four months of age and neighbourhood purchasing power, taking account of individual-level variables including maternal age, smoking and parental level of education. Data were obtained from a prospective population- based cohort study recruited from birth in 2007-2008 in the Halland region, southwestern Sweden. Questionnaire data on the individual-level variables and the outcome variable of breastfeeding at four months (yes/no) were used (n=2,407). Each mother was geo-coded with respect to her residential parish (there are 61 parishes in the region) and then stratified by parish-level household purchasing power. It emerged that four neighbourhood characteristics were reasonable to use, viz. <10%, 10-19%, 20-29% and ≥ 30% of the resident families with low purchasing power.RESULTS: The proportion of mothers not breastfeeding at four months of age showed a highly significant trend across the neighbourhood strata (p=0.00004): from 16.3% (< 10% with low purchasing power) to 29.4% (≥ 30% with low purchasing power), yielding an OR of 2.24 (95% confidence interval: 1.45-3.16). After adjusting for the individual-level variables, the corresponding OR=1.63 (1.07-2.56) was significant and the trend across the strata was still evident (p=0.05). A multi-level analysis estimated that, in the neighbourhoods with ≥ 30% of the families with low purchasing power, 20% more mothers than expected, taking account of the individual-level factors, reported no breastfeeding at four months of age (≥ 95% posterior probability of an elevated observed-to-expected ratio).CONCLUSION: The neighbourhood purchasing power provided a spatial determinant of low numbers of mothers breastfeeding at four months of age, which could be relevant to consider for targeted actions. The elevated observed-to-expected ratio in the neighbourhoods with the lowest purchasing power points toward a possible contextual influence. © 2013 Almquist-Tangen et al.; licensee BioMed Central Ltd.

Evaluation of a metal artifact reduction algorithm in CT studies used for proton radiotherapy treatment planning

- Metal objects in the body such as hip prostheses cause artifacts in CT images. When CT images degraded by artifacts are used for treatment planning of radiotherapy, the artifacts can yield inaccurate dose calculations and, for particle beams, erroneous penetration depths. A metal artifact reduction software (O-MAR) installed on a Philips Brilliance Big Bore CT has been tested for applications in treatment planning of proton radiotherapy. Hip prostheses mounted in a water phantom were used as test objects. Images without metal objects were acquired and used as reference data for the analysis of artifact-affected regions outside of the metal objects in both the O-MAR corrected and the uncorrected images. Water equivalent thicknesses (WET) based on proton stopping power data were calculated to quantify differences in the calculated proton beam penetration for the different image sets. The WET to a selected point of interest between the hip prostheses was calculated for several beam directions of clinical relevance. The results show that the calculated differences in WET relative to the reference case were decreased when the O-MAR algorithm was applied. WET differences up to 2.0 cm were seen in the uncorrected case while, for the O-MAR corrected case, the maximum difference was decreased to 0.4 cm. The O-MAR algorithm can significantly improve the accuracy in proton range calculations. However, there are some residual effects, and the use of proton beam directions along artifact streaks should only be used with caution and appropriate margins.

Doctors’ and Nurses’ Perceptions of Military Pre-hospital Emergency Care
- 2014

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this study was to identify physicians’ and nurses’ perceptions of military prehospital emergency care before and after an international mission. A qualitative empirical study with a phenomenographic approach was used. The aim is to identify the area of knowledge, pre-hospital care in a military environment, in terms of expressions from doctors and nurses focussing on the variation in how learning of pre-hospital care is perceived. The result of the study is a set of descriptive categories on a collective level, showing the variation in how doctors and nurses perceived the phenomenon of military pre-hospital emergency care. The results after predeployment training can be categorized as (1) to learn military medicine, (2) to take care of the casualty and (3) to have safety awareness. The results after an international mission can be categorized as (1) to collaborate with others, (2) to deliver general health care, and (3) to improve competence in military medicine. Possible implications of the results from the present study are the following; (I) better conditions for doctors and nurses to provide appropriate military medical care by clarification and better understanding of professions in the mission area (doctors, nurses, officers), since they may have different goals for their actions, (II) to pay attention to all aspects of military health care during predeployment training, including general health care in the mission area, (III) to implement new knowledge in military medicine in the predeployment training, and (IV) to train for the reality all doctors and nurses are about to meet. These results indicate that the training should be developed in order to optimize the prepare physicians and nurses for international assignments. This may result in increased safety for the provider of care, while at the same time minimizing suffering and enhancing the possibility of survival of the injured.

- The objective of this study is to examine how medics within the Swedish Armed Forces perceive their learning outcome following military prehospital training. A qualitative study with a phenomenographic approach was used to investigate how learning is perceived among military medics. At meta level, the results can be viewed as an interaction, i.e., being able to collaborate in the medical platoon, including the ability to interact within the group and being able to lead; an action, i.e., being able to assess and treat casualties, including the ability to communicate with the casualty, to prioritize, and to be able to act; and a reflection, i.e., having confidence in one's own ability in first aid, including being prepared and feeling confident. interaction during the period of education is important for learning. action, being able to act in the field, is based on a drill in which the subject progresses from simple to complex procedures. reflection, learning to help others, is important for confidence, which in turn creates preparedness, thereby making the knowledge meaningful.
