Prevalence and risk factors for transactional sex among Swedish-born and foreign-born MSM in Sweden
- 2022
-
In: BMC Public Health. - : BioMed Central (BMC). - 1471-2458. ; 22
-
Journal article (peer-reviewed)abstract
- Background: Little is known about transactional sex (TS) (selling and buying sex) among men who have sex with men (MSM) in Sweden, especially among foreign-born MSM. This study aims to assess the prevalence and risk factors of TS (ever and in the previous five years) among MSM living in Sweden and to determine if there is a difference between Swedish-born MSM and foreign-born MSM.Methods: Swedish data from a multicountry online banner survey (EMIS-2017) was used (n = 4443). Multivariable regression analysis was applied to analyse the data.Results: The prevalence of ever-selling sex among all MSM participants was 13.2% and 5.9% in the previous five years. Selling sex ever and in the previous five years was higher among foreign-born MSM (16% and 8.4%, respectively) than Swedish-born MSM (12.7% and 5.4%, respectively). Among all participants, younger age (aOR:3.19, 95% CI:1.57-6.45) and really struggling to live on current income (aOR:3.37, 95% CI:2.29-4.96) increased the odds of selling sex. Being foreign-born MSM (aOR:1.33, 95% CI:1.02-1.73) and having had sex with a woman in the previous 12 months increased the odds of selling sex (aOR:1.44, 95% CI:1.00-2.07). The prevalence of ever buying sex among MSM participants in Sweden was 10.8% and 6.7% in the previous five years, with the same trend among foreign-born MSM (11.6% and 6.9%, respectively) and Swedish-born MSM (10.7% and 6.6%, respectively). Higher education and not having a current partner increased the odds of buying sex. Younger age was protective for buying sex (aOR:0.05, 95% CI:0.02-0.14). Among the foreign-born MSM, the length of stay in Sweden decreased the odds of buying sex (aOR: 0.98, 95% CI: 0.96-0.99).Conclusions: The comparatively high prevalence of TS among MSM participants in Sweden, where buying sex is illegal, with a higher prevalence among foreign-born MSM participants, calls for sexual and reproductive health and rights interventions in this population. Increased attention, including HIV prevention programming and education, should be aimed at younger MSM, MSM struggling with their current income, and foreign-born MSM, as they are more likely to report selling sex.

Route optimization as an instrument to improve animal welfare and economics in pre-slaughter logistics
- 2018

Journal article (peer-reviewed)abstract
- Each year, more than three million animals are transported from farms to abattoirs in Sweden. Animal transport is related to economic and environmental costs and a negative impact on animal welfare. Time and the number of pick-up stops between farms and abattoirs are two key parameters for animal welfare. Both are highly dependent on efficient and qualitative transportation planning, which may be difficult if done manually. We have examined the benefits of using route optimization in cattle transportation planning. To simulate the effects of various planning time windows and transportation time regulations and number of pick-up stops along each route, we have used data that represent one year of cattle transport. Our optimization model is a development of a model used in forestry transport that solves a general pick-up and delivery vehicle routing problem. The objective is to minimize transportation costs. We have shown that the length of the planning time window has a significant impact on the animal transport time, the total driving time and the total distance driven; these parameters that will not only affect animal welfare but also affect the economy and environment in the pre-slaughter logistic chain. In addition, we have shown that changes in animal transportation regulations, such as minimizing the number of allowed pick-up stops on each route or minimizing animal transportation time, will have positive effects on animal welfare measured in transportation hours and number of pick-up stops. However, this leads to an increase in working time and driven distances, leading to higher transportation costs for the transport and negative environmental impact.

Corrigendum to “Cost of disorders of the brain in Europe 2010” [Eur. Neuropsychopharmacol. 21 (2011) 718–779]
- 2012
-
In: European Neuropsychopharmacology. - : Elsevier BV. - 0924-977X .- 1873-7862. ; 22:3, s. 237-238
-
Journal article (peer-reviewed)abstract
- The spectrum of disorders of the brain is large, covering hundreds of disorders that are listed in either the mental or neurological disorder chapters of the established international diagnostic classification systems. These disorders have a high prevalence as well as short- and long-term impairments and disabilities. Therefore they are an emotional, financial and social burden to the patients, their families and their social network. In a 2005 landmark study, we estimated for the first time the annual cost of 12 major groups of disorders of the brain in Europe and gave a conservative estimate of €386 billion for the year 2004. This estimate was limited in scope and conservative due to the lack of sufficiently comprehensive epidemiological and/or economic data on several important diagnostic groups. We are now in a position to substantially improve and revise the 2004 estimates. In the present report we cover 19 major groups of disorders, 7 more than previously, of an increased range of age groups and more cost items. We therefore present much improved cost estimates. Our revised estimates also now include the new EU member states, and hence a population of 514 million people.

Automation as an enabler: Passengers’ experience of travelling with a full-length automated bus and their expectations of a future public transport system
- 2023
-
In: Transportation Research Procedia. - 2352-1465 .- 2352-1457. ; 72, s. 957-964
-
Conference paper (peer-reviewed)abstract
- Twenty-two frequent public transport users experienced travelling with a fully automated, full-length bus on a test course that included nine simulated everyday traffic situations. Most participants experienced the journey as very positive and their trust in the automated system was high. In general, they were positive about using automated buses in the future but believed that this would not improve their travelling experience or change their travel behaviour without additional modifications to the system, such as dedicated public transport lanes etc. Many believed that the introduction of automated buses could create conditions for increased access to transport in rural areas and that the automated technology might enable new services that would have a great impact on public transport development, contributing a more individual, efficient and flexible public transport system.

In: Brain. - : Oxford University Press. - 0006-8950 .- 1460-2156. ; 129:Pt 2, s. 451-644

Journal article (peer-reviewed)abstract
- Mutant forms of superoxide dismutase-1 (SOD1) cause amyotrophic lateral sclerosis (ALS) by an unknown noxious mechanism. Using an antibody against a novel epitope in the G127insTGGG mutation, mutant SOD1 was studied for the first time in spinal cord and brain of an ALS patient. The level was below 0.5% of the SOD1 level in controls. In corresponding transgenic mice the content of mutant SOD1 was also low, although it was enriched in spinal cord and brain compared with other tissues. In the mice the misfolded mutant SOD1 aggregated rapidly and 20% occurred in steady state as detergent-soluble protoaggregates. The misfolded SOD1 and the protoaggregates form, from birth until death, a potentially noxious burden that may induce the motor neuron injury. Detergent-resistant aggregates, as well as inclusions of mutant SOD1 in motor neurons and astrocytes, accumulated in spinal cord ventral horns of the patient and mice with terminal disease. The inclusions and aggregates may serve as terminal markers of long-term assault by misfolded SOD1 and protoaggregates.

Journal article (peer-reviewed)abstract
- BACKGROUND: PZA resistance in multidrug-resistant tuberculosis (MDR-TB) is common and it is not clear how it affects interim and treatment outcomes. Although rarely performed, phenotypic drug susceptibility testing (pDST) is used to define PZA resistance but genotypic DST (gDST) and minimum inhibitory concentration (MIC) could be beneficial. We aimed to assess the impact of PZA gDST and MIC on time to sputum culture conversion (SCC) and treatment outcome in patients with MDR-TB.METHODS: Clinical, microbiological and treatment data was collected in this cohort study for all patients diagnosed with MDR-TB in Sweden 1992-2014. MIC, pDST and whole genome sequencing of the pncA, rpsA and panD genes were used to define PZA resistance. A Cox regression model was used for statistical analyses.RESULTS: Of 157 patients with MDR-TB, 56.1% (n=88) had PZA resistant strains and 49.7% (n=78) were treated with PZA. In crude and adjusted analyses, PZA gDST resistance was associated with a 29-day longer time to SCC (hazard ratio [HR] 0.57, 95% confidence interval [CI] 0.36-0.89, p=0.013 and HR 0.49, 95% CI 0.29-0.82, p=0.007, respectively). A two-fold decrease in dilutions of PZA MIC for PZA susceptible strains showed no association with SCC in crude or adjusted analyses (HR 0.98, 95% CI 0.73-1.31, p=0.89). Genotypic DST and MIC for PZA were not associated with treatment outcome.CONCLUSION: In patients with MDR-TB, gDST PZA resistance was associated with a longer time to SCC. Rapid PZA gDST is important to identify patients who may benefit from PZA treatment.
