Maternal and infant health development in southern Sweden, 1905-2015: Understanding the role of institutions and medical innovations

Using data from southern Sweden, this work analyses the development of maternal and infant health in five rural parishes and the town of Landskrona in Scania, Sweden, in the last 110 years. First, we address the overall development of maternal, perinatal and infant health using a range of indicators, such as maternal mortality, neonatal mortality, and stillbirth rates. We also describe how institu

Enhanced Optical Biosensing by Aerotaxy Ga(As)P Nanowire Platforms Suitable for Scalable Production

Sensitive detection of low-abundance biomolecules is central for diagnostic applications. Semiconductor nanowires can be designed to enhance the fluorescence signal from surface-bound molecules, prospectively improving the limit of optical detection. However, to achieve the desired control of physical dimensions and material properties, one currently uses relatively expensive substrates and slow e

Per-and Polyfluoroalkyl Substances and Risk of Myocardial Infarction and Stroke : A Nested Case–Control Study in Sweden

BACKGROUND: Per-and polyfluoroalkyl substances (PFAS) are widespread and persistent pollutants that have been associated with elevated cholesterol levels. However, data on incident cardiovascular disease (CVD) is lacking. OBJECTIVES: We investigated the association of exposure to PFAS with risk of myocardial infarction and stroke and, subsidiary, with baseline blood lipids. METHODS: This populatio

Obstacles and Opportunities in Information Transfer Regarding Medications at Discharge - A Focus Group Study with Hospital Physicians

Purpose: This qualitative study aimed to investigate experiences and perceptions of hospital physicians regarding the discharging process, focusing on information transfer regarding medications.Methods: By purposive sampling three focus groups were formed. To facilitate discussions and maintain consistency, a semi-structured interview guide was used. Discussions were audio recorded and transcribed

Clinical implications of genetic testing in familial intermediate and late-onset colorectal cancer

The genetic background of familial, late-onset colorectal cancer (CRC) (i.e., onset > age 50 years) has not been studied as thoroughly as other subgroups of familial CRC, and the proportion of families with a germline genetic predisposition to CRC remains to be defined. To define the contribution of known or suggested CRC predisposition genes to familial late-onset CRC, we analyzed 32 well-establi

The influence of adhesion molecules on binding and protein organization in cell contacts

Interactions between immune cells such as T cells and antigen-presenting cells (APCs) are integral for mounting an adaptive immune response. The interaction between the T cell receptor (TCR) and the antigen-presenting major histocompatibility complex (pMHC) on a contacting T cell and APC, is widely accepted to be the key interaction. If the interaction is favourable, then T cell activation occurs.

Quantum Fokker-Planck Master Equation for Continuous Feedback Control

Measurement and feedback control are essential features of quantum science, with applications ranging from quantum technology protocols to information-to-work conversion in quantum thermodynamics. Theoretical descriptions of feedback control are typically given in terms of stochastic equations requiring numerical solutions, or are limited to linear feedback protocols. Here we present a formalism f

Excited state dynamics in low-dimensional perovskite nanocrystals

Two-dimensional (2D) perovskites have emerged as promising building blocks for optoelectronic applications. To fabricate high-performance devices, the relation between the material structures and their function in terms of excited state and charge carrier dynamics need to be well understood. In this thesis, we investigate photophysics of 2D lead halide perovskite with different compositions to rev

Effects of the COVID-19 pandemic on patients with inflammatory joint diseases in Sweden : From infection severity to impact on care provision

Objectives To compare risks for COVID-19-related outcomes in inflammatory joint diseases (IJDs) and across disease-modifying antirheumatic drugs (DMARDs) during the first two waves of the pandemic and to assess effects of the pandemic on rheumatology care provision. Methods Through nationwide multiregister linkages and cohort study design, we defined IJD and DMARD use annually in 2015-2020. We ass

Unraveling electronic band structure of narrow-bandgap p-n nanojunctions in heterostructured nanowires

The electronic band structure of complex nanostructured semiconductors has a considerable effect on the final electronic and optical properties of the material and, ultimately, on the functionality of the devices incorporating them. Valence electron energy-loss spectroscopy (VEELS) in the transmission electron microscope (TEM) provides the possibility of measuring this property of semiconductors w

Measuring the properties of semiconductor nanowires with transmission electron microscopy

The extremely small feature size and total sample volume of semiconductor nanowire materials has meant that advanced techniques have been required for even the most routine sample characterization since the structures were first reported. Electron microscopy has been the technique of choice for fast and reliable determination of nanowire morphology, structure, and composition since the earliest re

Phonon transport and thermoelectricity in defect-engineered InAs nanowires

There have been reports of improvements in the thermoelectric figure of merit through the use of nanostructured materials to suppress the lattice thermal conductivity. Here, we report on a fundamental study of the combined effects of defect planes and surface scattering on phonon transport and thermoelectric properties of defect-engineered InAs nanowires. A microfabricated device is employed to me

A Mixture of Endocrine Disrupting Chemicals Associated with Lower Birth Weight in Children Induces Adipogenesis and DNA Methylation Changes in Human Mesenchymal Stem Cells

Endocrine disrupting chemicals (EDCs) are man-made compounds that alter functions of the endocrine system. Environmental mixtures of EDCs might have adverse effects on human health, even though their individual concentrations are below regulatory levels of concerns. However, studies identifying and experimentally testing adverse effects of real-life mixtures are scarce. In this study, we aimed at

Impact of the COVID-19 pandemic on morbidity and mortality in patients with inflammatory joint diseases and in the general population : A nationwide Swedish cohort study

Objectives To estimate absolute and relative risks for all-cause mortality and for severe COVID-19 in inflammatory joint diseases (IJDs) and with antirheumatic therapies. Methods Through Swedish nationwide multiregister linkages, we selected all adult patients with rheumatoid arthritis (RA, n=53 455 in March 2020), other IJDs (here: spondyloarthropathies, psoriatic arthritis and juvenile idiopathi

Per- and polyfluoroalkyl substances (PFAS) and male reproductive function in young adulthood; a cross-sectional study

Background: Per- and polyfluoroalkyl substances (PFAS) are a large family of persistent industrial chemicals with endocrine disrupting properties. Objectives: To examine biomarkers of reproductive function in young adult males according to current environmental exposure to single and combined PFAS. Methods: The study population consisted of young men (n = 1041, age 18–21) from the Fetal Programmin
