Travel time to care does not affect survival for patients with colorectal cancer in northern Sweden : A data linkage study from the Risk North database

INTRODUCTION: Numerous prior studies, even from countries with free access to care, have associated long travel time to care with poor survival in patients with colorectal cancer. METHODS: This is a data-linkage study of all 3718 patients with colorectal cancer, diagnosed between 2007 and 2013 in Northern Sweden, one of the most sparsely populated areas in Europe. Travel time to nearest hospital w

Association of acute myocardial infarction with influenza : A nationwide observational study

INTRODUCTION: Influenza may precipitate cardiovascular disease, but influenza typically peaks in winter, coinciding with other triggers of myocardial infarction (MI) such as low air temperature, high wind velocity, low atmospheric pressure, and short sunshine duration. OBJECTIVE: We aimed to determine the relationship of week-to-week variation in influenza cases and acute MI, controlling for meteo

Comparisons of Risk Factors for Abdominal Aortic Aneurysm and Coronary Heart Disease : A Prospective Cohort Study

Even though abdominal aortic aneurysm (AAA) and coronary heart disease (CHD) are both related to atherosclerosis, there could be important differences in risk factors. Based on Malmö Diet and Cancer Cohort, the incidence of AAA and CHD was followed prospectively. Cox regression was used to calculate the association of each factor with AAA and CHD and hazards ratio were compared using a modified Lu

Suppurative otitis media in Angola : clinical and demographic features

Objective: To describe the demographics and clinical findings in patients with otorrhoea in Angola. Methods: A total of 411 patients with otorrhoea presenting in the ear, nose and throat clinic in Luanda and healthcare centres in other Angolan provinces underwent interview and clinical examination. We describe the demographics and clinical characteristics of the patients. Results: The majority (64

Comparison of the evolution of orchids with that of bats

The evolution of orchids and bats is an example of DNA’s own evolution which has resulted in structures and functions which are not necessarily related to any obvious advantage to the organism. The flowers of orchids resemble: humans, apes, lizards, frogs and even shoes. The faces of bats resemble plant leaves but also horseshoes. These similarities are not accidental because they emerge repeatedl

Comparing progression biomarkers in clinical trials of early Alzheimer’s disease

Objective: To investigate the statistical power of plasma, imaging, and cognition biomarkers as Alzheimer’s disease (AD) clinical trial outcome measures. Methods: Plasma neurofilament light, structural magnetic resonance imaging, and cognition were measured longitudinally in the Alzheimer’s Disease Neuroimaging Initiative (ADNI) in control (amyloid PET or CSF Aβ42 negative [Aβ-] with Clinical Deme

Realizing the 2030 Agenda for sustainable development–engaging national parliaments?

This article examines the role of national parliaments in policy processes related to the realization of the 2030 Agenda for sustainable development, adopted in the UN General Assembly in 2015. We outline three main roles of parliaments in the case of national policy-making based on intergovernmental agreements: legislative and policy approval, citizen representation, and accountability. The cases

Credit expansion and socio-economic heterogeneity of debtors in foreclosure : the case of Sweden 2000–2014

Credit expansion is the trend of households gaining access to more credit. It is correlated with increasing socio-economic heterogeneity of indebted homeowners. Increasing heterogeneity implies that a more diverse span of homeowners is put at risk of foreclosure. This empirical study explores socio-economic heterogeneity in the case of Swedish debtors in foreclosure between 2000 and 2014. Employin

H-infinity Optimal Control for Systems with a Bottleneck Frequency

We characterize a class of systems for which the H-infinity optimal control problem can be simplified in a way that enables sparse solutions and efficient computation. For a subclass of the systems, an optimal controller can be explicitly expressed in terms of the matrices of the system's state-space representation. In many applications, the controller given by this formula, which is st

Individual Driving Behaviour in Wildfire Smoke

This work presents the results of a virtual reality (VR) experiment aiming at investigating how individual driving behaviour is affected by the presence of wildfire smoke. The experiment included a driving simulation task to study the chosen driving speed at different smoke densities and the lateral position of the driven car on the road cross section. During the VR experiment, participants were p

The making of green steel in the EU : a policy evaluation for the early commercialization phase

In the attempt to reduce greenhouse gas emissions from steel production, several large industry decarbonization projects have emerged in Europe. The commercialization of low-emission steel technology, however, faces systemic barriers such as a lack of infrastructure and unclear demand for greener steel. As part of its new commitment to climate-neutrality, the European Commission has announced plan

Direct and indirect selection on mate choice during pollen competition : Effects of male and female sexual traits on offspring performance following two-donor crosses

Mate choice in plants is poorly understood, in particular its indirect genetic benefits, but also the direct benefits of avoiding harmful matings. In the herb Collinsia heterophylla, delayed stigma receptivity has been suggested to enhance pollen competition, potentially functioning as a female mate choice trait. Previous studies show that this trait can mitigate the cost of early fertilization ca

Discriminative Accuracy of Plasma Phospho-tau217 for Alzheimer Disease vs Other Neurodegenerative Disorders

Importance: There are limitations in current diagnostic testing approaches for Alzheimer disease (AD). Objective: To examine plasma tau phosphorylated at threonine 217 (P-tau217) as a diagnostic biomarker for AD. Design, Setting, and Participants: Three cross-sectional cohorts: an Arizona-based neuropathology cohort (cohort 1), including 34 participants with AD and 47 without AD (dates of enrollme

A Brief Breathing Space : Experiences of Brief Admission by Self-Referral for Self-Harming and Suicidal Individuals with a History of Extensive Psychiatric Inpatient Care

Individuals with severe self-harm and experiences of lengthy psychiatric admissions often have complex mental health conditions and are at risk of suicide. In this qualitative study, self-harming individuals with >180 days of psychiatric admission over 12 months shared their experiences of Brief Admission (BA), a standardized crisis-management intervention encouraging self-admission and autonomy.

What to share, when, and where : balancing the objectives and complexities of open source software contributions

Context:: Software-intensive organizations’ rationale for sharing Open Source Software (OSS) may be driven by both idealistic, strategic and commercial objectives, and include both monetary as well as non-monetary benefits. To gain the potential benefits, an organization may need to consider what they share and how, while taking into account risks, costs and other complexities. Objective:: This st

Tinted, Detached, and Lazy CNF-XOR Solving and Its Applications to Counting and Sampling

Given a Boolean formula, the problem of counting seeks to estimate the number of solutions of F while the problem of uniform sampling seeks to sample solutions uniformly at random. Counting and uniform sampling are fundamental problems in computer science with a wide range of applications ranging from constrained random simulation, probabilistic inference to network reliability and beyond. The pas

The effect of hydration status on plasma FGF21 concentrations in humans: A subanalysis of a randomised crossover trial

AIM: Fibroblast growth factor 21 (FGF21) has recently been implicated in thirst in rodent models. The mechanisms for this are currently uncertain, and it is unclear whether hydration status can alter FGF21 concentrations, potentially providing an additional mechanism by which hypohydration induces thirst. The aim of this study is therefore to understand whether hydration status can alter circulati

Paradoxes in supply chains : a conceptual framework for packed products

Purpose: Grounded in paradox theory, and with the objective of structuring and extending existing knowledge of conflicts of interest (e.g. trade-offs) in packaging logistics, the purpose of this paper is to identify categories of paradoxical tensions in packaging systems used in supply chains, and to develop a conceptual framework that describes these categories.
