Tuning Viscoelasticity with Minor Changes in Speed of Sound in an Ultrasound Phantom Material

The acoustic properties of ultrasound phantom materials have always been important, but with new applications interrogating tissue mechanical properties, viscoelasticity has also become an interesting feature to consider. Along with Young's modulus, the viscous component of tissue is affected by certain diseases and can therefore be used as a biomarker. Furthermore, viscoelasticity varies between

Article 2: Definitions

Commentary on Article 2 of the UN Convention on the Rights of Persons with Disabilities

Psykiatrisk tvångsvård: tillåten (sär)behandling eller otillåten diskriminering?

Konventionen om rättigheter för personer med funktionsnedsättning (CRPD) innehåller en ny vision för den psykiatriska vården som bygger på principer om likabehandling och självbestämmande. Denna artikel analyserar innebörden av denna vision och dess implikationer för den svenska kontexten. Mitt syfte är att bidra till diskussionen om hur den psykiatriska tvångsvården bör regleras i Sverige. Fokus

Participation in Research and the CRPD

This article discusses the implications of the United Nations’ Convention on the Rights of Persons with Disabilities (“CRPD”) for domestic policies on research involving persons with disabilities, including those with limited decision-making abilities. It starts with an examination of the protection the Convention affords to persons with disabilities against being enrolled in research projects, an

Short-term reproducibility of parameters characterizing atrial fibrillatory waves

Objective: To study reproducibility of f-wave parameters in terms of inter- and intrapatient variation. Approach: Five parameters are investigated: dominant atrial frequency (DAF), f-wave amplitude, phase dispersion, spectral organization, and spatiotemporal variability. For each parameter, the variance ratio R, defined as the ratio between inter- and intrapatient variance, is computed; a larger R

ECG-Derived Respiratory Rate in Atrial Fibrillation

Objective: The present study addresses the problem of estimating the respiratory rate from the mor- phological ECG variations in the presence of atrial fibrilla- tory waves (f-waves). The significance of performing f-wave suppression before respiratory rate estimation is investi- gated. Methods: The performance of a novel approach to ECG-derived respiration, named “slope range” (SR) and de- signed

The Multi-Blade Boron-10-based neutron detector performance using a focusing reflectometer

The Multi-Blade is a Boron-10-based neutron detector designed for neutron reflectometers and developed for the two instruments (Estia and FREIA) planned for the European Spallation Source in Sweden. A demonstrator has been installed at the AMOR reflectometer at the Paul Scherrer Institut (PSI - Switzerland). AMOR exploits the Selene guide concept and can be considered a scaled-down demonstrator of

Evaluation of Very Integrated Program (VIP) : Health promotion for patients with alcohol and drug addiction - A Randomized Trial

BACKGROUND: Compared to the general population, patients with alcohol and drug addiction have an increased risk of additional hazardous lifestyles and suffer from more chronic diseases, adding to their already significantly higher morbidity and mortality. The objective of this study was to test the efficacy of the Very Integrated Program (VIP) on treatment and health outcomes for patients diagnose

Optimal Trade-Off between Economic Activity and Health during an Epidemic

This paper considers a simple model where a social planner can influence the spread-intensity of an infection wave, and, consequently, also the economic activity and population health, through a single parameter. Population health is assumed to only be negatively affected when the number of simultaneously infected exceeds health care capacity. The main finding is that if (i) the planner attaches a

Infections Related to the Use of Medical Devices and Changes in the Oropharyngeal Flora

Background: Humans exist in mutualistic balance with a large range of microbiota. Illness and hospitalization can disturb this balance and contribute to hospital-acquired infections (HAIs), which occur most often in critically ill patients. The use of medical devices such as central venous catheters (CVCs) and endotracheal tubes (ETTs) is essential in the care of critically ill patients. At the sa

Clonidine for pain in non-ventilated infants

BACKGROUND: Critically ill newborn infants undergo a variety of painful procedures or experience a variety of painful conditions during their early life in the neonatal unit. In the critically ill paediatric and neonatal population, clonidine is prescribed as an adjunct to opioids or benzodiazepines aiming to reduce the doses of these drugs that are required for analgesia or sedation, or to facili

Control of FtsZ-ring formation and cell division in Streptomyces venezuelae

Cell division is essential for all life forms. In bacteria, this fundamental process is precisely orchestrated by a protein, FtsZ, the ancestral homolog of eukaroytic tubulin. On the onset of division, at the division site, FtsZ assembles into a cytoskeleton structure - the Z ring - that recruits other division proteins and constricts the membrane together with cell wall synthesizing machinery, ev

Anfall av gåshud visade sig vara anti-LGI-1-encefalit

Anti-LGI-1 encephalitis is a type of autoimmune encephalopathy, where antibodies react against the cell surface protein leucine-rich glioma inactivated protein 1 (LGI-1). It presents with a subacute confusion, changes in behaviour, short-term memory deficits and seizures. A piloerectile semiology is common, which has been described as reflecting insular ictal activity. Patients may have temporal l

Cerebrospinal fluid p-tau217 performs better than p-tau181 as a biomarker of Alzheimer’s disease

Cerebrospinal fluid (CSF) p-tau181 (tau phosphorylated at threonine 181) is an established biomarker of Alzheimer’s disease (AD), reflecting abnormal tau metabolism in the brain. Here we investigate the performance of CSF p-tau217 as a biomarker of AD in comparison to p-tau181. In the Swedish BioFINDER cohort (n = 194), p-tau217 shows stronger correlations with the tau positron emission tomography

Poor academic performance in offspring of survivors with childhood or adolescent central nervous system tumor in Sweden

The number of children who were born after their parents were diagnosed with central nervous system (CNS) tumor is increasing, but it remains largely unknown regarding the academic performance of these children. We aimed to investigate whether children of survivors with childhood or adolescent CNS tumor were associated with poor academic performance. Children of survivors of CNS tumor were identif
