Severe conditions and lack of cure for many amyloid diseases make it highly desired to understand the underlying principles of formation of fibrillar aggregates (amyloid). Here, amyloid formation from peptides was studied using Monte Carlo simulations. Systems of 20, 50, 100, 200 or 500 hexapeptides were simulated. Association kinetics were modeled equal for fibrillar and other (inter- and intra-p
Background: Rare variants of the triggering receptor expressed on myeloid cell 2 (TREM2) gene are strong risk factors for Alzheimer’s disease (AD), and drugs targeting the TREM2 protein are being developed. However, it is unknown what the effect of TREM2 variants is on the AD phenotype. Methods: Here we studied a full range of clinical and biomarker measures in a large cohort of TREM2 variant carr
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
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
IntroductionData regarding the impact of adenomyosis on the outcomes after in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment are conflicting. Standardized diagnostic criteria are prerequisites for studying a potential association between adenomyosis and IVF/ICSI treatment outcomes. This study aims to examine the cumulative live birth rate (CLBR) after the first IVF/
Background: Hearing loss is estimated to affect more than 20% of the global population. Hearing aid fitting is a common intervention in audiological rehabilitation; however, there are still those who struggle with remaining communication difficulties that require additional intervention. The group rehabilitation program Active Communication Education (ACE) has been shown to be an effective alterna
Given the current societal and political developments in Germany, the visibility and integration of-marginalized is essential to ensure their inclusion in mainstream society. One way of encouraging-contact between majority and marginalized groups is through building social networks, of which-informal and nonformal educational activities play an important part. This thesis examines the-experience o
Mäns våld mot kvinnor och våld i nära relation utgör ett allvarligt samhälls- och jämställdhetsproblem. För att synliggöra våldet infördes år 1998 brottet grov kvinnofridskränkning i brottsbalkens 4 kap. 4 a § 2 st. Brottet var avsett att fånga upprepade kränkningar inom ramen för en nära relation som begås av en man mot en kvinna. Uppsatsen syftar till att redogöra för gällande rätt, samt undersöMen’s violence against women and violence in intimate relationships consti-tute a serious social and gender equality issue. To raise awareness of this violence, the crime of gross violation of a woman’s integrity was introduced in 1998 under Chapter 4, Section 4a, Paragraph 2 of the Penal Code. The crime was intended to address repeated violations within the context of an intimate relationship com
Childhood cancer aetiology is poorly understood and is considered to originate in utero and early postnatal life. In this study, we investigated perinatal characteristics as potential risk factors by performing a population-based case-control study, including 1340 cancer cases diagnosed < 19y and born between 1989–2021 in southern Sweden, and 13400 controls matched by sex, year, and municipality o
Biodiversity hotspots are biogeographic regions exceptionally rich in endemic species showing high rates of habitat loss, making them the priority of global conservation efforts. As part of the biodiversity hotspot with the highest density of endemic species, the West Usambara Mountains in Tanzania require an efficient and resourceful monitoring solution. This thesis aimed to model the tree specie
AIMS: Metformin has hitherto not been proven superior to other type 2 diabetes (T2D) medications for the prevention of organ complications. The aim of this study is to report baseline data and blinded interim analyses in the register-based randomised clinical trial (RRCT) SMARTEST, which compares metformin and the SGLT2 inhibitor dapagliflozin in early T2D. We also present learnings from the novel
Background: Various plasma phosphorylated tau species have been shown to be associated with amyloid-β (Aβ) PET and Tau PET in Alzheimer’s disease (AD), but whether APOE ε4 affects the interaction between glial fibrillary acidic protein (GFAP) and phosphorylated tau (pTau), and whether a three-way interaction exists among APOE ε4, GFAP, and pTau that influences AD progression remain unclear. Method
BACKGROUND: Differences in cardiac sarcoidosis between racial groups remain understudied. Therefore, this study aims to explore race differences in patients with cardiac sarcoidosis. METHODS: We analyzed data from the Cardiac Sarcoidosis Consortium, an international registry including over 25 centers. The primary clinical outcome was a composite end point of all-cause mortality, left ventricular a
Cervical cancer is a leading cause of morbidity and mortality in women worldwide. The availability of prophylactic vaccines for high-risk types of human papillomavirus (HPV) infection represents an important advancement in the prevention of cervical cancer. In Jordan, the availability of the HPV vaccination is restricted to individuals who are willing to pay. The aim of the current study was to ev
Background: Accurately quantifying the risk of osteoporotic fracture is important for directing appropriate clinical interventions. While skeletal measures such as heel quantitative speed of sound (SOS) and dual-energy X-ray absorptiometry bone mineral density are able to predict the risk of osteoporotic fracture, the utility of such measurements is subject to the availability of equipment and hum
Background: A novel data-driven classification of type 2 diabetes has been proposed to personalise anti-diabetic treatment according to phenotype. One subgroup, severe insulin-resistant diabetes (SIRD), is characterised by mild hyperglycaemia but marked hyperinsulinaemia, and presents an increased risk of diabetic nephropathy. We hypothesised that patients with SIRD could particularly benefit from
Background: Substance use among older persons occurs with medical and psychiatric comorbidities. This study examined the associations of substance use disorder (SUD), psychiatric, and dual diagnoses with 12-month cumulative hospitalized days, hospital admission rate and number of days to first hospitalization.Methods: The cohort of 3,624 individuals (28.2% women) aged 50 years or older was assesse
Background: Alzheimer’s disease is a progressive, irreversible, and fatal disease for which accumulation of amyloid beta is thought to play a key role in pathogenesis. Aducanumab is a human monoclonal antibody directed against aggregated soluble and insoluble forms of amyloid beta. Objectives: We evaluated the efficacy and safety of aducanumab in early Alzheimer’s disease. Design: EMERGE and ENGAG
BACKGROUND: Individuals are exposed to air pollution and ionizing radiation from natural sources through inhalation of particles. This study investigates the association between cardiac arrhythmias and short-term exposures to fine particulate matter (particulate matter ≤2.5 µm aerodynamic diameter; PM2.5) and particle radioactivity.METHODS: Ventricular arrhythmic events were identified among 176 p
Background: Knee pain is studied mostly in older age groups, although in young adults it may be an indicator of future impaired musculoskeletal health. Therefore, the aim of this study was to examine the longitudinal association between knee pain and thigh muscle strength in young adult women and to explore the associations between muscle strength, body composition, physical activity and knee pain
