Comparison of Group-Level and Individualized Brain Regions for Measuring Change in Longitudinal Tau Positron Emission Tomography in Alzheimer Disease

Importance: Longitudinal tau positron emission tomography (PET) is a relevant outcome in clinical trials evaluating disease-modifying therapies in Alzheimer disease (AD). A key unanswered question is whether the use of participant-specific (individualized) regions of interest (ROIs) is superior to conventional approaches where the same ROI (group-level) is used for each participant. Objective: To

Coastal signals of environmental changes: foraminifera as benthic monitors

Climate changes, tightly linked to anthropogenic activities, are significantly altering environments and ecosystems globally, such as by increasing marine and coastal deoxygenation or occurrences of extreme weather events. The significance of paleoenvironmental and -climate reconstructions, as well as monitoring of current conditions, for unravelling baseline natural variation, today’s changes and

Do Dual-mobility Cups Reduce Revision Risk in Femoral Neck Fractures Compared With Conventional THA Designs? An International Meta-analysis of Arthroplasty Registries

Dual-mobility cups in THA were designed to reduce prosthesis instability and the subsequent risk of revision surgery in high-risk patients, such as those with hip fractures. However, there are limited data from clinical studies reporting a revision benefit of dual-mobility over conventional THA. Collaboration between anthroplasty registries provides an opportunity to describe international practic

Targeted proteomics identifies potential biomarkers of dysglycaemia, beta cell function and insulin sensitivity in Black African men and women

Aims/hypothesis: Using a targeted proteomics approach, we aimed to identify and validate circulating proteins associated with impaired glucose metabolism (IGM) and type 2 diabetes in a Black South African cohort. In addition, we assessed sex-specific associations between the validated proteins and pathophysiological pathways of type 2 diabetes. Methods: This cross-sectional study included Black So

Recovery from Breast Cancer : Investigating the role of resilience in breast cancer survivorship

Bröstcancer är vanligt förekommande bland kvinnor, en av tio kvinnor får en bröstcancerdiagnos under sin livstid. Upplevelsen av bröstcancer är en komplex process, som innebär ett flertal sammanlänkade stressfulla händelser. Det är därför tydligt att sättet personen reagerar på sådana stressorer kan ha en betydande påverkan på både fysisk och psykisk hälsa. Resiliens är ett konstrukt som innefattaBreast cancer is a common event among women, one in ten women receiving a breast cancer diagnosis in their lifetime. The experience of breast cancer is a complex process that entails a multitude of interlinked potentially highly stressful events. It is thus evident that the manner in which one reacts to such stressors can have a substantial impact on both physical and mental health. Resilience is

Rates of Progression in Patients with Alzheimer’s Disease Depending on Apolipoprotein E Genotype and Concomitant Medications.

Background: The apolipoprotein E (APOE) ε4 allele is associated with higher cholesterol levels, and an increased risk of developing Alzheimer’s disease (AD) and amyloid-related imaging abnormalities after initiation of amyloid-modifying therapies. A worse cognitive response to cholinesterase inhibitor (ChEI) treatment and longitudinal outcome in APOE ε4-carriers has been observed. Based on these c

Liv I kyrkan (Life in the church) : Final Repprt

Målet med detta projekt var att studera hur tre församlingar i tre kyrkliga miljöer – Odarslövskyrka (Torns församling), Ignaberga nya kyrka (Hässleholms församling), och Östra Nöbbelövs kyrka (Simrishamns församling) i Lunds stift – skulle kunna utveckla sina kyrkliga miljöer för egen del och i samverkan för att öka tillgängligheten till de kyrkliga miljöerna och utveckla dem till meningsfulla anThe objective of this project was to study how three congregations/parishes in three church environments – Odarslövs kyrka (Torn’s parish), Ignaberga nya kyrka (Hässleholm’s parish), and Östra Nöbbelövs kyrka (Simrishamn’s parish) in the Diocese of Lund – could develop the church environments under their auspices in order to increase their accessibility and forms of meaningful use for members of t

A Voice Beyond the Edge: Michael Edgerton's "Anaphora" : Nonlinear dynamics in the extra-normal voice

The recital is focused on my research involving contemporary voice. My approach to singing research is becoming more systematic as the result of beginning to work on concepts central to the extra-normal voice, term coined by Michael Edward Edgerton. This approach to voice is based on voice science, the aims of which are to investigate the boundaries and/or limits of vocal sound production. In this

Longer Interval Between First Colonoscopy With Negative Findings for Colorectal Cancer and Repeat Colonoscopy

IMPORTANCE: For individuals without a family history of colorectal cancer (CRC), colonoscopy screening every 10 years is recommended to reduce CRC incidence and mortality. However, debate exists about whether and for how long this 10-year interval could be safely expanded.OBJECTIVE: To assess how many years after a first colonoscopy with findings negative for CRC a second colonoscopy can be perfor

Emerging biomarkers in cardiometabolic disease

AbstractThe epidemiological association between diabetes and heart failure is well-established and the two entities areemerging as global threats, both individually and synergistically, to an aging population. The exploration of multipleproteins can shed light on pathophysiological pathways in both diabetes and cardiovascular disease. This canpossibly provide novel diagnostic, prognostic and hopef

Diatom-rich sediment formation in lakes

Unicellular photosynthetic golden algae called diatoms are one of the most abundant silicifying organisms. Diatoms take up silicon and build their frustules, in the form of biogenic silica (BSi), which have high preservation potential, and thus are found in sediments. Around 27 % of the annual dissolved silicon (DSi) delivery from the land to the ocean is retained in lakes and reservoirs in the fo

Surface guided radiotherapy

AbstractModern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment. The foremost technological approaches have been intensity modulated radiotherapy (IMRT) and intensity modulated proton therapy (IMPT) in combination with image guided radiotherapy (IGRT). IMRT and IMPT is characterized by a moModern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment.

Nanofiltration of kraft black liquor : Process development and techno-economic evaluation

Kraft black liquor (KBL) is a side-stream that is produced during the kraft pulping process, and mainly contains lignin, hemicelluloses, and cooking chemicals, namely sodium hydroxide and sodium sulphide. KBL is usually evaporated and burned in a recovery boiler in order to recover the cooking chemicals and generate energy. However, pulp mills are sometimes limited by the capacity of their recover

Convection-diffusion-reaction models of sedimentation : Numerical approximation, analysis of solutions and inverse problems

The core of this Doctoral thesis is mainly based in the studies of one-dimensional initial-boundary value problems, which are given by a single non-linear hyperbolic partial differential equation (PDE) with non-convex flux function, or by a system of strongly degenerate parabolic PDEs, for the simulation of sedimentation processes of solid particles immersed in a fluid. Particular attention is pai

Evolutionary dynamics of migration and breeding in wild birds: genetic architecture, sexual conflicts and evolutionary constraints

Our knowledge of the evolutionary potential of traits involved in different selective episodes, especially in natural populations, is still limited. This is true for questions such as the genetic basis and inheritance of traits, how natural and sexual selection acts on them, and how selective conflicts influence the evolutionary response to selection. In my thesis, I investigate these questions, u

Inguinal Hernia Surgery in Men - Chronic Pain and Sexual Dysfunction

Life time occurrence of inguinal hernia is 30% of men. Most are symptomatic and will require surgical treatment. Operation will commonly cure the hernia but remaining chronic pain or new pain is seen in 10–15%. Groin pain due to an inguinal hernia can cause impairment of sexual functions. This is sparsely studied. The aim was to analyse postoperative long term chronic pain and sexual impairment in

Modern roles for an ancient system. Intracellular Complement in the regulation of β cell function

Type 2 diabetes (T2D) is characterised by defective insulin exocytosis from the pancreatic β cells, accompanied by insulin resistance. Reduced β cells mass is often seen in T2D individuals, caused by enhanced β cells apoptosis. It is now understood that several components drive β cells dysfunction and apoptosis. These are glucose-and lipo-toxicity, ER stress, pro-inflammatory cytokines, dysfunctio
