Background and Objectives Structural brain MRI and blood-based phosphorylated tau (p-tau) measures are among the least invasive and least expensive Alzheimer's disease (AD) biomarkers to date. The extent to which these biomarkersmay outperformone another in predicting future Alzheimer dementia diagnosis is poorly understood, however. This study investigated 2 specific AD biomarkers, i.e., a cortic

Background: A juxtarenal abdominal aortic aneurysm is defined as a short (less than 4mm) or no-neck aneurysm, which is often treated with open or complex endovascular repair. The evidence to support the best treatment strategy is scarce. The aim of this study was to assess the short- and mid-term outcomes of elective open surgical repair or fenestrated endovascular aneurysm repair for juxtarenal a

BACKGROUND: Medical students navigate a complex landscape of digital tools with potential to enhance learning. The main objectives of the current study were to investigate which digital resources are being used, which background factors are associated with utilization, perceived advantages and disadvantages of different digital resources, and explore future directions.METHODS: Cross-sectional, nat

Objective: To analyze the outcomes of urgent/emergent endovascular aortic repair of patients with free/contained ruptured thoracoabdominal aortic aneurysms (rTAAA). Background: Endovascular repair of rTAAA has been scarcely described in emergent setting. Methods: An international multicenter retrospective observational study (ClinicalTrials.govID:NCT05956873) from January 2015 to January 2023 in 6

Background: MR-generated acoustic noise may be particularly concerning at 7-Tesla (T) systems. Noise levels can be reduced by altering gradient output using software optimization. However, such alterations might influence image quality or prolong scan times, and these optimizations have not been well characterized. Purpose: To evaluate image quality, sound pressure levels (SPLs), and perceived noi

Between 1992 and 2004, 1,140 children (1 to < 15 years) were diagnosed with B-cell precursor acute lymphoblastic leukemia (ALL) in the Nordic countries. Of these, 288 (25%) were positive for t(12; 21)(p 13;q22) [ETV6/RUNXI]. G-banding analyses were successful in 245 (85%); 43 (15%) were karyotypic failures. The modal chromosome numbers, incidence, types, and numbers of additional abnormalities, ge

Studies, mainly from the UK, show that many farmland birds have declined as a result of recent agricultural intensification. We tested this idea by analysing farmland bird population trends in Sweden, a country displaying less dramatic agricultural changes and less intensive agriculture. Specifically we investigated whether (i) farmland specialists have declined more than generalists, (ii) populat

Aims/hypothesis Genetic and epidemiological studies suggest an association between gestational diabetes mellitus and type 2 diabetes. Both are polygenic multifactorial disorders characterised by beta cell dysfunction and insulin resistance. Our aim was to investigate whether common genetic variants that have previously been associated with type 2 diabetes or related phenotypes would also confer ri

Popular Abstract in Swedish I Sverige analyseras omkring 40 000 DNA-prover från brottsplatser varje år. DNA-profilerna jämförs mot DNA-profiler från misstänkta personer och kan på så vis användas för att knyta en person till ett brott. Alla typer av kroppsvävnader kan analyseras, såsom blod, saliv och hudceller. Vanliga bevismaterial är cigarettfimpar, flaskor, burkar och kläder. De material som cDNA evidence, linking perpetrators to crime scenes, is central to many legal proceedings. However, crime scene samples often contain extraneous substances that may interfere with the PCR-based forensic analysis, resulting in partial or negative DNA profiles. Extensive DNA purification may remove inhibitors, but involves the risk of DNA loss. In this work, pre-PCR processing was applied to improve

Environmental concerns such as global warming, the surge of crude oil prices and more stringent emission regulations are demanding the development of internal combustion engines that are highly efficient and low polluting. With classical internal combustion engine concepts such as diesel compression ignition and gasoline spark ignition engines, a trade-off exists between local and global emissions

Background: Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) using magnitude inversion recovery (IR) or phase sensitive inversion recovery (PSIR) has become clinical standard for assessment of myocardial infarction (MI). However, there is no clinical standard for quantification of MI even though multiple methods have been proposed. Simple thresholds have yielded varying re

Background: The aim of this study was to examine in elderly men a relationship between depressive symptoms, peripheral vascular disease and cerebral blood flow (CBF). Methods: Population-based cohort study started with an examination of 809 men at age 55, followed by the first (age 68ys) and second follow up (age 82ys). 128 survivors were examined at age 82 with Tc-99m-HMPAO-SPECT to estimate CBF,

Intermittent Parathyroid Hormone (PTH)((1-34)) has an established place in osteoporosis treatment, but also shows promising results in models of bone repair. Previous studies have been dominated by closed fracture models, where union is certain. One of the major clinical needs for anabolic therapies is the treatment of open and high energy fractures at risk of non-union. In the present study we th

The study is based on monitoring data on the seasonal variation during four (1996-1999) vegetation periods, as well as long-term summer data on submerged vegetation, nutrients, light, phyto-plankton and zooplankton in Lake Krankesjon, a shallow, calcium-rich, moderately eutrophic take in southern Sweden. The lake has been in the clear water state with abundant submerged vegetation since the end of

Soft tissue sarcomas (STS) represent a group of rare and heterogenous tumors that optimally should be diagnosed and treated within multidisciplinary teams. This thesis has studied various aspects ? pathological, genetical, and clinical ? of STS. In study I, we demonstrated that 20% of the patients in a population-based series of 818 STS developed second primary malignancies. An increased risk of

BACKGROUND: Dietary factors are thought to have an important role in gastric and esophageal carcinogenesis, but evidence from cohort studies for such a role is lacking. We examined the risks of gastric cancer and esophageal adenocarcinoma associated with meat consumption within the European Prospective Investigation Into Cancer and Nutrition (EPIC) cohort. METHODS: A total of 521,457 men and women

This study investigates the toxic effect of E(2)nonenal (trans-2-nonenal, T2N) and its conjugate with horse muscle myoglobin (Mb) tested on murine cell line L929 and human cell line A549, as well as the genotoxic effect of these compounds assayed by measuring of micronuclei in human cells K562. It is an aldehyde, which is occurring as the substance responsible for an off flavour in aged beers, but

Background: The maintenance of postural control is fundamental for different types of physical activity. This can be measured by having subjects stand on one leg on a force plate. Many studies assessing standing balance have previously been carried out in patients with ankle ligament injuries but not in patients with ankle fractures. The aim of this study was to evaluate whether patients operated

Objective. Increasing survival of extremely low birth weight (ELBW; birth weight < 1000 g) infants raises a concern regarding the risks of adverse long-term outcome such as cognitive dysfunction. Few studies have reported long-term follow-up of representative regional cohorts. The objective of this study was to assess the 5-year outcome of a prospectively followed national ELBW infant cohort.
