Factors Associated with Health-Related Quality of Life in Late-Stage Parkinson's Disease

Background: There is limited knowledge on health-related quality of life (HRQoL) in late-stage Parkinson's disease (PD). Objective: To assess factors associated with HRQoL in patients with late-stage PD, with a focus on health care provision. Methods: The Care of Late Stage Parkinsonism (CLaSP) project is the largest study on late-stage PD to date. The current study analyzed data of 401 patients f

Cross-sectional and longitudinal medial temporal lobe subregional atrophy patterns in semantic variant primary progressive aphasia

T1-magnetic resonance imaging (MRI) studies report early atrophy in the left anterior temporal lobe, especially the perirhinal cortex, in semantic variant primary progressive aphasia (svPPA). Improved segmentation protocols using high-resolution T2-MRI have enabled fine-grained medial temporal lobe (MTL) subregional measurements, which may provide novel information on the atrophy pattern and disea

Preheart failure comorbidities and impact on prognosis in heart failure patients : a nationwide study

Background: Data regarding the impact of preheart failure (HF) comorbidities on the prognosis of HF are scarce, especially in the younger HF patients. Objectives: To investigate pre-existing comorbidities in HF patients versus matched controls and to assess their impact on mortality. Methods: We included all first-time in-hospital and outpatient diagnoses of HF from 1995 to 2017, and comorbidities

Compass cue integration and its relation to the visual ecology of three tribes of ball-rolling dung beetles

To guide their characteristic straight-line orientation away from the dung pile, ball-rolling dung beetles steer according to directional information provided by celestial cues, which, among the most relevant are the sun and polarised skylight. Most studies regarding the use of celestial cues and their influence on the orientation system of the diurnal ball-rolling beetle have been performed on be

A highly-detailed anatomical study of normal pericardial structures as revealed by in-vivo computed tomography and magnetic resonance images and ex-vivo novel 3D reconstructions from Visible Human Server

The pericardial cavity, sinuses, and recesses are frequently depicted on Computed Tomography (CT) and Magnetic Resonance (MR). We here review the normal human pericardial structures as provided by MR imaging of young, healthy subject and CT scans acquired after iatrogenic coronary dissection. We compared such radiological information with cadaveric axial and sagittal sections of the human body pro

Response of the peatland carbon dioxide sink function to future climate change scenarios and water level management

Stress factors such as climate change and drought may switch the role of temperate peatlands from carbon dioxide (CO2) sinks to sources, leading to positive feedback to global climate change. Water level management has been regarded as an important climate change mitigation strategy as it can sustain the natural net CO2 sink function of a peatland. Little is known about how resilient peatlands are

Heterogeneous Returns to Medical Innovations

This paper sets up a quasi-experiment to estimate both total and heterogeneous impacts of medical innovations on the individual’s economic outcomes for a comprehensive set of around 90 health conditions. The rich administrative panel data for Sweden covering more than 1 million individuals combined with disease-specific data on new molecular entities and patents granted in healthcare have allowed

Treatment of ARS deficiencies with specific amino acids

Purpose: Recessive cytosolic aminoacyl-tRNA synthetase (ARS) deficiencies are severe multiorgan diseases, with limited treatment options. By loading transfer RNAs (tRNAs) with their cognate amino acids, ARS are essential for protein translation. However, it remains unknown why ARS deficiencies lead to specific symptoms, especially early life and during infections. We set out to increase pathophysi

Coronary heart disease in mothers and fathers of adult children with alcohol use disorders

Background and aim: Having a family member with an alcohol use disorder (AUD) may negatively affect a person's health. Our aim was to study the long-term risk of coronary heart disease (CHD) in parents who have an offspring with AUD. Design: Cohort study with Cox regression models and co-sibling analyses. Setting: Sweden. Participants: From population registers, we selected all parent-offspring pa
