The Swedish Sea Rescue Society’s (SSRS) maritime Search and Rescue (SAR) op- erations can be enhanced through the use of fixed-wing unmanned aerial vehicles (UAVs), which offer extended range and rapid area coverage. However, recovering such aircraft aboard small, moving rescue vessels remains a significant challenge due to continuous wave-induced motion (pitch, roll, and yaw) and the absence of c
Background: This meta-analysis investigated the effects of enhanced recovery after surgery (ERAS) protocols compared to conventional care on postoperative outcomes in patients aged 70 years or older undergoing pancreatoduodenectomy (PD). Methods: Five databases were systematically searched. Comparative studies with available individual patient data (IPD) were included. The main outcomes were posto
Aim: How the ability of plants to move towards newly favourable habitats (dispersal limitation) impacts the change of biome distribution and transition under fast climate warming is still debated. Analysing vegetation change in the past may help to clarify the relative importance of underlying ecological processes such as climate, biotic interactions, and dispersal. In this study, we investigated
Experience of out-of-home care (OHC) is associated with life-long vulnerability, and research indicates that parents with experiences of OHC are at higher risk of having their own children placed in out-of-home care. However, research on these parents is limited and lacks a resilience perspective. Here, we focused on parents with OHC experience as children but with custody of their own children (N
IMPORTANCE: The outcomes of newborn infants of women testing positive for SARS-CoV-2 in pregnancy is unclear.OBJECTIVE: To evaluate neonatal outcomes in relation to maternal SARS-CoV-2 test positivity in pregnancy.DESIGN, SETTING, AND PARTICIPANTS: Nationwide, prospective cohort study based on linkage of the Swedish Pregnancy Register, the Neonatal Quality Register, and the Register for Communicab
Importance: Clonal hematopoiesis of indeterminate potential (CHIP) may contribute to the risk of atrial fibrillation (AF) through its association with inflammation and cardiac remodeling. Objective: To determine whether CHIP was associated with AF, inflammatory and cardiac biomarkers, and cardiac structural changes. Design, Setting, and Participants: This was a population-based, prospective cohort
Popular Abstract in Swedish Allt liv på jorden har utvecklats i en vattenbaserad miljö. Proteiner och andra biomolekyler har därigenom anpassats i sin struktur och funktion till vattnets speciella egenskaper. För att kunna förstå biologiska processer måste vi studera hur biomolekyler växelverkar med det omgivande vattnet under fysiologiska betingelser. Detta är särkilt viktigt eftersom det flesta The results presented in this thesis demonstrate that the magnetic relaxation dispersion (MRD) technique can provide information of relevance to protein biophysics, magnetic resonance imaging and cell biology. By immobilizing proteins with covalent cross-links, intermittent protein dynamics on the previously inaccessible ns-µs time scale could be probed with MRD via the exchange of water molecule
The aim of this thesis was to evaluate long-term outcomes in a regional cohort of adolescents born extremely preterm (before the 29th gestational week) and compare them to full-term born controls. Fifty-two prematurely and 54 full-term born individuals were recruited from a follow-up study at 10 years of age. The participant rate was 85 % from the prematurely born group and 89 % from the full-term
Most stars form in a clustered environment. Both single and binary stars will sometimes encounter planetary systems in such crowded environments. Encounter rates for binaries may be larger than for single stars, even for binary fractions as low as 10-20 per cent. In this work, we investigate scatterings between a Sun-Jupiter pair and both binary and single stars as in young clusters.We first perfo
Background: ICU prognostication is difficult because of patients’ prior comorbidities and their varied reasons for admission. The model used for ICU prognostication in Sweden is the Simplified Acute Physiology Score 3 (SAPS 3), which uses information gathered within one hour of ICU admission to predict 30-day mortality. Since the SAPS 3 model was introduced, no biomarkers have been added to it to
Global climate change is driving species' distributions towards the poles and mountain tops during both non-breeding and breeding seasons, leading to changes in the composition of natural communities. However, the degree of season differences in climate-driven community shifts has not been thoroughly investigated at large spatial scales. We compared the rates of change in the community composition
Young birds in cold environments face a range of age-specific thermal challenges. Studying the thermal biology of young birds throughout ontogeny may further our understanding of how such challenges are met. We investigated how age and environmental parameters influenced surface temperature gradients across various body regions of wandering albatross (Diomedea exulans) chicks on Bird Island, South
Alternative reproductive tactics (ARTs) have provided valuable insights into how sexual selection and life history trade-offs can lead to variation within a sex. However, the possibility that tactics may constrain evolution through intralocus tactical conflict (IATC) is rarely considered. In addition, when IATC has been considered, the focus has often been on the genetic correlations between the A
OBJECTIVES: Pain is a major symptom in patients with rheumatoid arthritis (RA). In early RA, pain is usually due to synovitis, but can also persist despite effective anti-inflammatory treatment. The objective of this study was to investigate the pain course over time and predictors of unacceptable pain and unacceptable pain with low inflammation, in patients with early RA.METHODS: An inception coh
Background: Chronic pain in children can significantly impact daily functioning. While interdisciplinary pain rehabilitation is the recommended treatment, it is resource-intensive and limited in availability. Therefore, children with more complex symptoms, classified as High Impact Chronic Pain (HICP), need to be prioritized for interdisciplinary pain rehabilitation. However, HICP in children has
Carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKp) represents a growing clinical threat due to convergence of resistance and virulence determinants. We conducted a multicenter genomic epidemiology study analysing CR-hvKp isolates collected from 19 tertiary-care hospitals across Türkiye between 2018 and 2023. CR-hvKp isolates were subjected to whole-genome sequencing to investigate
We investigate the ecological and evolutionary variables that best explain spatial diversity patterns of anuran amphibians in three of South America's most diverse and geographically widespread biomes: the Cerrado, Amazonia, and Atlantic Rainforest. We used Conditional Autoregressive Models to assess the potential influence of present-day climate (temperature and precipitation), historical climate
Wildfires are a natural disturbance shaping boreal forests, but their effects on soil microbial communities and biogeochemical cycling remain unclear, particularly in Fennoscandia. We investigated the impact of fire severity and post-fire management on the soil microbial community two years after a boreal wildfire in Sweden. We quantified growth rates of bacteria, saprotrophic fungi (SF), ectomyco
The invention of the laser in 1960 gave us the ruby laser, which generally produced chaotic pulses of light. Six years later, in 1966, a concept called passive mode-locking applied to neodymium-glass lasers produced reasonably well-behaving picosecond pulses. This triggered an intense activity, with respect to developing improved laser pulse sources, measurement techniques, and application to chem
Background: The Nordic Nutrition Recommendations (NNR) are developed to promote public health and to prevent food-related diseases such as obesity and cardiovascular diseases. Objective: To investigate the nutrient intake and adherence to the NNR in a Swedish cohort with abdominal obesity. Design: Dietary intake data were collected using 3-day food diaries and anthropometry and clinical chemistry
