  • Lone threats : a register-based study of Swedish lone actors
  • 2024
  • Ingår i: International Journal of Comparative and Applied Criminal Justice. - : Routledge. - 0192-4036 .- 2157-6475. ; 48:1, s. 75-94
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigates 30 lone actors in Sweden with a register-based design using a group of male lone actors and two reference groups: same-sex siblings and other male violent extremists. We compare lone actors to the reference groups along social background, criminal background, and co-offending relations (1995 –2016), and mental health (1980–2016). Our results show that lone actors are primarily born in Sweden to two Swedish-born parents. They have a high degree of criminality and cooffending, indicating that they are not completely loners in their criminal behaviour. They have higher enrolment in secondary education than the reference groups, but lower enrolment in higher education than other male violent extremists. Additionally, they suffer considerably more from mental disorders compared to the reference groups. An analysis of criminality and in- and outpatient hospitalisation over the life course indicates that lone actors may have had problems in their transition into middle age.

  • Despite reductions in muscle mass and muscle strength in adults with CHD, the muscle strength per muscle mass relationship does not differ from controls
  • 2021
  • Ingår i: Cardiology in the Young. - : Cambridge University Press. - 1047-9511 .- 1467-1107. ; 31:5, s. 792-798
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Patients with CHD exhibit reduced isometric muscle strength and muscle mass; however, little is known how these parameters relate. Therefore, the aim was to investigate the relation between isometric limb muscle strength and muscle mass for patients in comparison to age- and sex-matched control subjects.METHODS: Seventy-four patients (35.6 ± 14.3 years, women n = 22) and 74 matched controls were included. Isometric muscle strength in elbow flexion, knee extension, and hand grip was assessed using dynamometers. Lean mass, reflecting skeletal muscle mass, in the arms and legs was assessed with dual-energy x-ray absorptiometry.RESULTS: Compared to controls, patients had lower muscle strength in elbow flexion, knee extension, and hand grip, and lower muscle mass in the arms (6.6 ± 1.8 kg versus 5.8 ± 1.7 kg, p < 0.001) and legs (18.4 ± 3.5 kg versus 15.9 ± 3.2 kg, p < 0.001). There was no difference in achieved muscle force per unit muscle mass in patients compared to controls (elbow flexion 0.03 ± 0.004 versus 0.03 ± 0.005 N/g, p = 0.5; grip strength 0.008 ± 0.001 versus 0.008 ± 0.001 N/g, p = 0.7; knee extension 0.027 ± 0.06 versus 0.028 ± 0.06 N/g, p = 0.5). For both groups, muscle mass in the arms correlated strongly with muscle strength in elbow flexion (patients r = 0.86, controls, r = 0.89), hand grip (patients, r = 0.84, controls, r = 0.81), and muscle mass in the leg to knee extension (patients r = 0.64, controls r = 0.68).CONCLUSION: The relationship between isometric muscle strength and limb muscle mass in adults with CHD indicates that the skeletal muscles have the same efficiency as in healthy controls.

  • Risk factors for surgically treated cervical spondylosis in male construction workers: a 20-year prospective study
  • 2023
  • Ingår i: The spine journal. - : Elsevier. - 1529-9430 .- 1878-1632. ; 23:1, s. 136-145
  • Tidskriftsartikel (refereegranskat)abstract
    • Background ContextDegenerative changes due to cervical spondylosis (CS) can detrimentally affect work ability and quality of life yet understanding of how physical exposure affects disease progression is limited.PurposeTo assess the associations between occupational physical exposures and occurrence of surgically treated cervical spondylosis (ST-CS) and early exit from the labour market via disability pension.Study Design/SettingProspective register study with 20 year follow-up period.Patient SampleSwedish construction workers participating in a national health surveillance project conducted between 1971-1993.Outcome MeasuresSurgically treated cervical spondylosis (ST-CS) and early labour market exit at a minimum rate of 25% time on disability pension.MethodsAssociations between occupational physical exposures (job exposure matrix) and subsequent ST-CS (National Hospital in-patient register) and early labour market exit via disability pension (Swedish Social Insurance Agency register) were assessed in a cohort of male construction workers (n=237,699).ResultsA total of 1381 ST-CS cases were present and a 20-year incidence rate of 35.1 cases per 100,000 person years (95% confidence interval (CI) 33.2-36.9). Increased relative risk (RR) for ST-CS was found for workers exposed to non-neutral (RR 1.40, 95% CI 1.15-1.69) and awkward neck postures (1.52, 1.19-1.95), working with the hands above shoulder height (1.30, 1.06-1.60), and high upper extremity loading (1.35, 1.15-1.59). Increased risk was also present for workers who reported frequent neck (3.06, 2.18-4.30) and upper back (3.84, 2.57-5.73) pain in the 12 months prior to survey. Among workers with elevated arm exposure, higher risk was seen in those who also had more frequent neck pain. ST-CS cases took early retirement more often (41.3%) and at a younger age (53 years) than the total study cohort (14.8% and 56 years of age, respectively).ConclusionsOccupational exposure to non-neutral neck postures, work with hands above shoulders and high loads born through the upper extremities increased the risk for ST-CS and early retirement due to disability. Decreasing postural and load exposure is salient for primary, secondary, and tertiary prevention of CS. Neck pain was shown to be a prognostic factor for ST-CS, which stresses the importance of acting early and taking preventative action to reduce workplace exposure, and the need for systematic medical check-ups within primary or occupational care to mitigate disease progression and early labour market exit due to disability.

  • Accelerometer-measured versus selfreported physical activity levels in women before and up to 48months after Roux-enY Gastric Bypass
  • 2020
  • Ingår i: BMC Surgery. - : BioMed Central. - 1471-2482. ; 20:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Roux-en-Y Gastric Bypass (RYGB) patients overestimate their time spent in moderate-to-vigorous physical activity (MVPA) to a greater extent post-surgery than pre-surgery. However, there is no data on discrepancy between self-reported and accelerometer-measured MVPA beyond nine months post-RYGB. The aim was to investigate how the duration of MVPA (main outcome) differs when comparing a self-administered questionnaire to accelerometer-data from pre-surgery and up to 48months post-RYGB.Methods: Twenty-six (38%) RYGB-treated women with complete data from the original cohort (N=69) were included. Participants were recruited from five Swedish hospitals. Mean pre-surgery BMI was 38.9 (standard deviation (SD)=3.4) kg/m2 and mean age 39.9 (SD=6.5) years. MVPA was subjectively measured by a selfadministered questionnaire and objectively measured by the ActiGraph GT3X+ accelerometer at 3months pre-RYGB and 9- and 48months post-RYGB. Means and SD were calculated at 3months pre- and 9- and 48months postRYGB. We calculated the P-values of the differences with Wilcoxon Signed-Rank test. For correlations between the self-administered questionnaire and the accelerometers, Spearman’s rank correlation was used.Results: Participants significantly overestimated (i.e. self-reported more time spent in MVPA compared to accelerometry) their MVPA in a higher degree post- compared to pre-RYGB surgery. Compared to pre-surgery, selfreported MVPA increased with 46.9 and 36.5% from pre- to 9- and 48months, respectively, whereas changes were a 6.1% increase and 3.5% decrease with accelerometers. Correlations between self-reported and accelerometermeasured MVPA-assessments were poor at all measurement points (r=0.21–0.42) and only significant at 48months post-RYGB (P=0.032).Conclusions: The discrepancy between self-reported and objectively assessed MVPA within the same individual is greater up to 48months post-RYGB compared to before surgery. To help bariatric patients understand and hopefully increase their physical activity behaviors post-surgery, objective measures of physical activity should be used.

  • Physical activity in women attending a dissonance-based intervention after Roux-en-Y Gastric Bypass : A 2-year follow-up of a randomized controlled trial
  • 2021
  • Ingår i: PLOS ONE. - : Public Library of Science (PLOS). - 1932-6203. ; 16:11
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The majority of Roux-en-Y gastric bypass (RYGB) patients are not sufficiently physically active post-surgery, yet little support from the Swedish healthcare system is offered. We investigated if a dissonance-based group intervention, aiming to increase health-related quality of life after surgery, had any effect on patients' physical activity two years post-RYGB.METHODS: Women undergoing RYGB surgery were recruited from five Swedish hospitals and randomized to intervention or control group (standard post-surgery care). The dissonance-based intervention was conducted three months post-RYGB and consisted of four group sessions, each with a specific topic, of which one addressed physical activity. ActiGraph GT3X+ accelerometers were used to measure physical activity at pre-RYGB, one- and two-years post-surgery.RESULTS: At pre-RYGB, 259 women were recruited and randomized (intervention n = 156 and control n = 103). Participants had a mean age of 44.7 years (SD 10.3) and pre-RYGB body mass index of 40.8 (SD 4.5) kg/m2. At two-years follow-up, 99 participants (63.5%) in intervention group and 68 (66.0%) in control group had valid accelerometer-measurements. Pre- to post-surgery increases were seen in all physical activity outcomes, but no statistically significant differences between the groups were observed at the two-years follow-up, and intervention effects were poor (d = 0.02-0.35).CONCLUSION: To our knowledge, this is the first dissonance-based intervention targeting women undergoing RYGB surgery. At two-years follow-up, we did not observe any differences in physical activity levels between the intervention group and control group.Trial registration number: ISRCTN16417174.

  • Meeting physical activity recommendations is associated with health-related quality of life in women before and after Roux-en-Y gastric bypass surgery
  • 2019
  • Ingår i: Quality of Life Research. - : Springer. - 0962-9343 .- 1573-2649. ; 28:6, s. 1497-1507
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: Meeting physical activity (PA) recommendations is positively associated with health-related quality of life (HRQoL), but it is still unclear whether PA (specifically objectively measured) is associated with HRQoL in bariatric surgery candidates, both before and after surgery. Thus, the aim of this study was to examine the cross-sectional association between meeting objectively measured PA recommendations and HRQoL before and after Roux-en-Y gastric bypass (RYGB) surgery.METHODS: Sixty-six women undergoing RYGB with pre-surgery and 62 women with post-surgery valid PA and HRQoL data were included from the control group of a RCT study aiming at improving HRQoL and PA post-RYGB surgery. Measures before and 12 months after RYGB included the Short Form Health Survey (SF-36) and objectively measured PA, sedentary time (ST), and step counts with GT3X+ accelerometers. Multiple linear regression models were used to analyze the associations between PA and HRQoL.RESULTS: Participants who engaged in more than 150 min of moderate to vigorous PA (MVPA)/week (PA recommendations) had considerably higher SF-36 scores (HRQoL) than those who did not, both pre and 12-month post-surgery, with greatest difference in the subscale bodily pain, 15.5 (p = 0.021) higher score (higher scores means less pain) pre-surgery and a 19.7 (p = 0.004) higher score post-surgery. Higher LPA and step counts and lower ST also showed positive associations in some of the subscales of SF-36.CONCLUSIONS: Meeting the PA recommendations and overall engaging in more PA was associated with higher HRQoL, pre-, and post-RYGB surgery, highlighting the importance of PA both pre- and post-surgery.

  • Calf Muscle Oxygenation is Impaired and May Decline with Age in Young Patients with Total Cavopulmonary Connection
  • 2022
  • Ingår i: Pediatric Cardiology. - : Springer. - 0172-0643 .- 1432-1971. ; 43:2, s. 449-456
  • Tidskriftsartikel (refereegranskat)abstract
    • Patients palliated with Total Cavopulmonary Connection have a lower muscle mass and a lower exercise capacity. We assessed calf muscle oxidative metabolism during and after heel raise exercise to exhaustion in young patients with TCPC compared to healthy peers. Near-infrared spectroscopy was used for measuring oxygen metabolism in the medial portion of the gastrocnemius muscle. Forty-three patients with TCPC, aged 6–18 years, were compared with 43 age and sex-matched healthy control subjects. Subgroups were formed to include children (6–12 years) and adolescents (13–18 years) to determine if these age groups influenced the results. During exercise, for the patients compared to controls there was a lower increase in deoxygenated hemoglobin (oxygen extraction) (5.13 ± 2.99au vs. 7.75 ± 4.15au, p = 0.001) and a slower rate of change in total hemoglobin (blood volume) (0.004 ± 0.015au vs 0.016 ± 0.01au, p = 0.001). Following exercise, patients exhibited a slower initial increase in tissue oxygenation saturation index (0.144 ± 0.11au vs 0.249 ± 0.226au, p = 0.007) and a longer half-time to maximum hyperemia (23.7 ± 11.4 s vs 16.8 ± 7.5 s, p = 0.001). On the subgroup level, the adolescents differed compared to healthy peers, whereas the children did not. Young patients with TCPC had impaired oxidative metabolism during exercise and required a longer time to recover. In that the differences were seen in the adolescent group and not in the children group may indicate a declining function with age.

  • Effect on energy and macronutrient intake with partial replacement of external food supply by in-house cooking at a nursing home for older people in Sweden
  • 2015
  • Ingår i: International Journal of Consumer Studies. - : Wiley. - 1470-6423 .- 1470-6431. ; 39:4, s. 369-379
  • Tidskriftsartikel (refereegranskat)abstract
    • An increased awareness of the importance of nutrition for older people's health and quality of life has underpinned projects and quality improvements for the meal situation in care establishments. The present study took place in a nursing home in a village outside an average-sized town situated in mid-Sweden. Care staff had initiated a change from external catered meals to purchase the food and cook the main meals themselves. The intention was to increase flexibility in accommodating the requests and needs of the elderly and, in doing so, to achieve increased professional pride and satisfaction. To ensure that no negative effects resulted for the residents in the nursing home, outcomes were evaluated through the present intervention study. The objective was to investigate whether and, if so, how their energy and nutrient intake and weight were affected. At the start, only one main hot meal was exchanged for home cooking to avoid work load problems as no increased costs were allowed and no extra staff were to be recruited. The study population consisted of 21 residents, aged 69-97 years. Weight, energy and nutrient intake were recorded before and during the intervention by 3-day food records validated by Goldberg's cutoff method. The same 3 days of the weekSunday to Tuesdayand the same menus were used for both measurement periods. At group level, the energy intake corresponded to the estimated energy requirements, both at baseline and at follow-up, although the intervention resulted in a significantly higher energy intake from the meals cooked in the ward kitchens. Two-thirds of the residents (n=13) slightly increased in weight from baseline to follow-up, while two participants (with body mass index 27.5 kg/m(2) and 33.5 kg/m(2), respectively) lost 5.0 kg and 6.9 kg, respectively. The total protein intake was insufficient both at baseline and follow-up and only met the participants' needs to 8122% and 83 +/- 26%, respectively. In conclusion, the intervention resulted in no adverse consequences for participants in terms of energy and nutrient intake. Most participants were weight stable or had small increases in weight, and the greatest weight gain was observed in the lighter clients. The low protein intake at both time points causes concern and suggests the need for further nutritional interventions to optimize older people's protein intake.

  • Effects of Task Demands on Olfactory, Auditory, and Visual Event-Related Potentials Suggest Similar Top-Down Modulation Across Senses
  • 2018
  • Ingår i: Chemical Senses. - : Oxford University Press (OUP). - 0379-864X .- 1464-3553. ; 43:2, s. 129-134
  • Tidskriftsartikel (refereegranskat)abstract
    • A widely held view is that top-down modulation of sensory information relies on an amodal control network that acts through the thalamus to regulate incoming signals. Olfaction lacks a direct thalamic projection, which suggests that it may differ from other modalities in this regard. We investigated the late positive complex (LPC) amplitudes of event-related potentials (ERP) from 28 participants, elicited by intensity-matched olfactory, auditory and visual stimuli, during a condition of focused attention, a neutral condition, and a condition in which stimuli were to be actively ignored. Amplitudes were largest during the attend condition, lowest during the ignore condition, with the neutral condition in between. A Bayesian analysis resulted in strong evidence for similar effects of task across sensory modalities. We conclude that olfaction, despite its unique neural projections, does not differ from audition and vision in terms of task-dependent neural modulation of the LPC.

  • Late stage pine litter decomposition : Relationship to litter N, Mn, and acid unhydrolyzable residue (AUR) concentrations and climatic factors
  • 2015
  • Ingår i: Forest Ecology and Management. - : Elsevier BV. - 0378-1127 .- 1872-7042. ; 358, s. 41-47
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this paper is to evaluate relationships between decomposition rates of Scots pine (Pinus sylvestris) and lodgepole pine (Pinus contorta var. contorta) needle litter in the late stage of decomposition (>30% accumulated mass loss), and the progressively changing concentrations of manganese (Mn), nitrogen (N), and acid unhydrolyzable residue (AUR), as well as mean annual temperature (MAT) and mean annual precipitation (MAP). Using available long-term decomposition studies on pine needle litter in a climate gradient in Sweden, we calculated annual mass loss and related to concentrations of Mn, N, and AUR at the start of each one-year period as well as to MAT and MAP. We investigated these relationships for (i) all data on annual mass loss combined and (ii) annual mass loss for five different decomposition categories as defined by accumulated mass loss. We found highly significant, negative, and dominant relationships between annual mass loss and N (R2=0.39) and AUR (R2=0.39), a slight but significant positive relationship to Mn (R2=0.08) and a significant negative relationship to MAT (R2=0.06). The relationships were dynamic, and changed with accumulated mass loss. The rate-dampening effect of N decreased to be a rate-enhancing effect at c. 60-80% accumulated mass loss. A similar trend was found for AUR, becoming rate-enhancing at 70-80% accumulated mass loss. For Scots pine needle litter the effect of MAT on mass loss decreased with increasing accumulated mass loss and changed to a rate-dampening effect at c. 50-70% accumulated mass loss. Mn showed a stimulating effect on mass loss rate in all categories whereas MAP showed no effect in this mainly boreal climatic gradient. The current approach indicates a method for detailed studies of rate-regulating factors for litter decomposition.
