Background: Per- and polyflouralkyl substances (PFAS) are a group of persistent chemicals used extensively in industries and consumer products due to their water-repellent properties. Studies have linked PFAS exposure to adverse health effects, and human exposure to PFAS, especially during pregnancy, is of great concern. In this study, we report how serum PFAS concentrations during pregnancy corre

Objective: To highlight experiences from a personal data incident, which occurred during recruitment for a project focused on how housing choices and relocation are related to active and healthy ageing. Results: Based on established collaboration, the researchers and representatives of housing companies planned for recruitment. Invitations to participate was distributed to persons registered with

Background: Data in Ethiopia on the epidemiology of Respiratory Syncytial Virus (RSV) and subtypes among influenza-like illness (ILI) and severe acute respiratory infections (SARI) cases is limited. Here, we assessed the epidemiology of RSV and its subtypes among the pediatric and adult ILI /SARI cases in Ethiopia. Methods: We conducted prospective, multicenter facility-based study from May 2023 t

Using population reconstructions from linked civil certificates for the province of Zeeland, the Netherlands, for the period 1812–1913, I study the social gradient in maternal mortality. Maternal mortality is defined as deaths in the first 42 days after the birth of a child. Among the women — mother to at least one child and followed between age 20 and 45 — maternal mortality constitutes about one

Registry-based randomised controlled trials (R-RCTs) represent a paradigm shift in research, with the potential to accomplish pragmatic but large trials with high external validity. In this paper, we review our experiences from planning and performing the REgistry-based randomised controlled trial of treatment Duration and mortality in long-term OXygen therapy (REDOX) trial, the first R-RCT within

Background: Prostate cancer screening depends on a careful balance of benefits, in terms of reduced prostate cancer mortality, and harms, in terms of overdiagnosis and overtreatment. We aimed to estimate the effect on overdiagnosis of restricting prostate specific antigen (PSA) testing by age and baseline PSA. Methods: Estimates of the effects of age on overdiagnosis were based on population based

We report on the fabrication of a self-aligned regrown In0.53Ga0.47As metal-oxide-semiconductor field-effect transistor (MOSFET) and a resonant tunneling diode (RTD). The performance of these devices is demonstrated by integrating them in parallel with an inductive coplanar waveguide stub to form a highly energy-efficient 70-GHz wavelet generator. The fast switching and low on-resistance of the MO

In the Swedish crisis management system, the municipalities have a great responsibility. One part of this responsibility concerns preparing for crises by making risk and vulnerability analyses as well as plans for how to handle extraordinary events. Such preparedness planning involves municipal officials and consequently their conceptions of their organisations’ crisis management capabilities. Thi

Transitioning into retirement is an under-researched phenomenon in developing countries. Largely, this is linked to a predominance of contexts where –in particular –the rural population remains outside the coverage of any formal pension system. In 2008, China introduced the New Rural Social Pension (NRSP), a program which by now covers the majority of the Chinese rural elderly. This paper examines

Fighting infectious disease in the past, much like today, focused on isolating the disease and thereby stopping its spread. New insights into the modes of transmission and the causal agents in the mid-nineteenth century, together with fear of new epidemic outbreaks, motivated public investments aimed at reducing mortality from infectious disease. Combining longitudinal individual-level data on 17,

Background: COPD is defined as partly irreversible airflow obstruction. The response pattern of bronchodilators has not been followed in advanced lung function parameters. Purpose: The aim of this study was to investigate bronchodilator response pattern in advanced lung function parameters in a continuous fashion along forced expiratory volume in 1 second (FEV1) percent predicted (%p) in COPD pati

We report electrical characterization of quantum dots formed by introducing pairs of thin wurtzite (WZ) segments in zinc blende (ZB) InAs nanowires. Regular Coulomb oscillations are observed over a wide gate voltage span, indicating that WZ segments create significant barriers for electron transport. We find a direct correlation of transport properties with quantum dot length and corresponding gro

We report growth and characterization of a coupled quantum dot structure that utilizes nanowire templates for selective epitaxy of radial heterostructures. The starting point is a zinc blende InAs nanowire with thin segments of wurtzite structure. These segments have dual roles: they act as tunnel barriers for electron transport in the InAs core, and they also locally suppress growth of a GaSb she

Societal functions constitute of public and private organisations and companies that provide commodities and services that are vi-tal for the functioning of the modern society. The public are highly dependent on these vital societal services and commodities, such as power supply, health care and education. In this paper we present an application of a method for collecting and structuring data and
