Fuel cells, redox flow batteries and some water desalination technologies such as reverse osmosis and electrodialysis require efficient ion exchange membranes to perform in an optimum way. Thus, by enhancing the properties of these membranes there is a possibility to improve this type of applications and technologies. Depending on the specific application, anion or proton exchange membranes with g
INTRODUCTION: Previous studies have shown an increased risk of obstetric complications in pregnancies after oocyte donation (OD). The present study includes all singletons born after OD during 10 years in Sweden.MATERIAL AND METHODS: A retrospective cohort study that included data from all Swedish in vitro fertilization (IVF) clinics between 2003 and 2012 was performed. Data were cross-linked with
This licentiate thesis in industrial design concerns the challenge and opportunity to meet the demographic changes and the future senior market. The aim is to explore how various user-centered design methods can be combined, modified and practiced to create conditions for the design of totally new or improved products. Design is understood as a process to develop solutions with the starting point
Industrial biotechnology has been defined as the use and application of biotechnology for the sustainable processing and production of chemicals, materials and fuels. It makes use of biocatalysts such as microbial communities, whole-cell microorganisms or purified enzymes. Although biocatalysts are considered advantageous, since they operate under mild conditions regarding temperature and pH and e
Background: Lewy body Dementia (LBD) is a well-known neurocognitive disorder in the elderly. The hallmarks of LBD are Parkinsonism without tremor, recurrent and persistent visual hallucinations often with insight, fluctuating cognition and alertness, rapid eye movement (REM) sleep behavior disorder with vivid dreams and violent movements, but relatively preserved memory functions. Nevertheless, LB
Little is known about risk factors for central nervous system (CNS) relapse in mature T-cell and natural killer cell neoplasms (MTNKNs). We aimed to describe the clinical epidemiology of CNS relapse in patients with MTNKN and developed the CNS relapse In T-cell lymphoma Index (CITI) to predict patients at the highest risk of CNS relapse. We reviewed data from 135 patients with MTNKN and CNS relaps
BACKGROUND: In Bangladesh, diarrhoea in children under-five is a major public health problem with cost implications. Although under-five diarrhoea mortality and morbidity have declined from 2007 to 2018, change in the economic burden is unknown. This study determined the change in the societal economic burden of under-five diarrhoea in Bangladesh comparing 2007 to 2018.METHODS: A prevalence-based,
The aim of the creation of this cohort was to investigate patterns of health and health care utilisation before and during the COVID-19 pandemic, overall and in relation to specific diagnoses, among people with intellectual disabilities (ID) compared to the general population. People living in Skåne, the southernmost region of Sweden, on 1st of January 2014 with at least one diagnosis of ID (ICD-1
PURPOSE: Cisplatin-based combination chemotherapy (CHT) is standard of care in metastatic urothelial cancer (mUC); however, no predictive molecular biomarkers are available for clinical use. The aim of this study was to investigate the impact of molecular subtypes in relation to treatment response and survival in patients with mUC treated with first-line CHT.PATIENTS AND METHODS: Molecular subtype
Background. Survivors of sepsis may experience long-term risk of increased morbidity and mortality, but estimations of cause-specific effects beyond 1 year after a sepsis episode are lacking. Method. This nationwide population-based cohort study linked data from national registers to compare patients aged ≥18 years in Sweden admitted to an intensive care unit from 2008 to 2019 with severe communit
AIMS/HYPOTHESIS: The aim of this work was to explore molecular amino acids (AAs) and related structures of HLA-DQA1-DQB1 that underlie its contribution to the progression from stages 1 or 2 to stage 3 type 1 diabetes.METHODS: Using high-resolution DQA1 and DQB1 genotypes from 1216 participants in the Diabetes Prevention Trial-Type 1 and the Diabetes Prevention Trial, we applied hierarchically orga
BACKGROUND: European guidelines recommend the use of a 0h/1h hs-cTn (high-sensitivity cardiac troponin) protocol in patients with acute chest pain. We aimed to determine the performance of this protocol in routine care when supplemented with patient history and ECG and a recommendation to refrain from noninvasive testing in low-risk patients.METHODS AND RESULTS: This was a pre- and postimplementat
Background: High-resolution computed tomography (HRCT) is dependent on detailed morphology in diagnostic assessment of interstitial lung diseases. Photon-counting CT (PCCT) enables improved resolution while reducing radiation. Purpose: To compare if the image quality, detailed morphology, and radiation dose in HRCT of the lung improves with PCCT compared to energy-integrated CT (EICT). Material an
Background: Sex and gender influence many aspects of chronic obstructive pulmonary disease (COPD). Limited data are available on this topic in alpha-1 antitrypsin deficiency (AATD). We therefore aimed to investigate sex issues in the EARCO registry, a prospective, international, observational cohort study. Methods: Baseline data from PiZZ individuals, enrolled in the registry with complete data on
Objective To estimate the prevalence of the curable sexually transmitted infections (STIs) Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis and Treponema pallidum, to identify associated risk factors and to assess ciprofloxacin resistance in N. gonorrhoeae-positive specimens among female sex workers (FSWs) in Guinea-Bissau. Methods For this cross-sectional
Wheat straw (WS) constitutes a considerable biomass resource and can be used to produce the energy carrier methane through anaerobic digestion. Due to the low contents of several nutrient elements and water in harvested WS, the use of sewage sludge (SS), consisting of primary sludge and waste-activated sludge, as a nutrient source in co-digestion with steam-pretreated wheat straw (PWS) was investi
Background: The diagnosis and treatment of childhood acute lymphoblastic leukemia (ALL) may impact mental health. We investigated the long-term risk of psychiatric disorders among survivors of ALL in a population-based cohort study. Methods: We identified patients diagnosed with ALL in Denmark and Sweden before age 20 during 1982–2008. Survivors of ALL (n = 2026), their siblings (n = 3027), and po
Aim: Assess effects on waist circumference from diet with or without cereal grains and with or without long-term physical exercise. Background: Elevated waist circumference is an indicator of increased abdominal fat storage and is accordingly associated with increased cardiovascular mortality. This is likely due to the association between lifestyle-induced changes in waist circumference and cardio
A novel pretreatment approach was developed in the present study to simultaneously reduce the content of inorganic troubling elements (TEs) and improve biomass energy density, i.e., combined leaching and steam explosion (SE) pretreatment with mechanical pressing. Three different high-ash-containing biomass feedstocks were studied – wheat straw (WS), spruce bark (SB), and empty fruit bunches of oil
RATIONALE: Preterm infants diagnosed with bronchopulmonary dysplasia (BPD) are thought to have fewer and larger alveoli than their term peers, but it is unclear to what degree this persists later in life.OBJECTIVES: To investigate to what degree the distal airspaces are enlarged in adolescents born preterm and to evaluate the new Airspace Dimension Assessment (AiDA) method in investigating this gr
