Migraine associated with altitude : results from a population-based study in Nepal

Background and purpose: A 1988 pilot study in Peru suggested an association between migraine and chronic exposure to high altitude. This study provides epidemiological evidence corroborating this. Methods: In a cross-sectional nationwide population-based study, a representative sample of Nepali-speaking adults were recruited through stratified multistage cluster sampling. They were visited at home

Sensitivity of Sentinel-1 backscatter to characteristics of buildings

In this study, Sentinel-1 interferometric wide swath (IW) mode backscatter is analysed with respect to physical parameters of buildings in Tallinn, Estonia. Dependence on height, alignment, density, shape, and material is shown and discussed. Distribution of backscatter was estimated with respect to each of the parameters, and a correlation matrix of all physical parameters and backscatter values

Monomeric and fibrillar α-synuclein exert opposite effects on the catalytic cycle that promotes the proliferation of Aβ42 aggregates

The coaggregation of the amyloid-β peptide (Aβ) and α-synuclein is commonly observed in a range of neurodegenerative disorders, including Alzheimer’s and Parkinson’s diseases. The complex interplay between Aβ and α-synuclein has led to seemingly contradictory results on whether α-synuclein promotes or inhibits Aβ aggregation. Here, we show how these conflicts can be rationalized and resolved by de

Doctors Doing Gender at Eye Clinics—Gender Constructions in Relation to Waiting Times for Cataract Extractions in Sweden

Why do eye clinics differ in their waiting times for women’s and men’s access to cataract extraction (CE)/“grå starroperation”? Taking a doing-gender perspective as the starting point, this study explores how gender constructions embedded in Swedish eye clinics contribute to longer waiting times for women than for men. Focus group interviews were conducted with doctors at two Swedish eye clinics:

Slipped capital femoral epiphysis : A population-based study

Background: Slipped capital femoral epiphysis (SCFE) is the most common hip disorder in children 9-15 years old. This is a population-based study in Sweden presenting the epidemiology for SCFE. Methods: In a prospective cohort study, we analysed pre- and postoperative radiographs, medical records for all children treated for SCFE in Sweden 2007-2013, demographic data, severity of slip and surgical

Protein S100B in umbilical cord blood as a potential biomarker of hypoxic-ischemic encephalopathy in asphyxiated newborns

BACKGROUND: Neonatal hypoxic ischemic encephalopathy (HIE) is a devastating condition resulting from a sustained lack of oxygen during birth. The interest in identifying a relevant biomarker of HIE has thrown into limelight the role of protein S100B as a clinical diagnostic marker of hypoxic brain damage in neonates.AIMS: To evaluate the diagnostic value of protein S100B, measured in umbilical cor

Trends in treatment with antipsychotic medication in relation to national directives, in people with dementia - a review of the Swedish context

Background: The aim of this study was to explore trends in treatment with antipsychotic medication in Swedish dementia care in nursing homes as reported in the most recent empirical studies on the topic, and to relate these trends to directives from the national authorities. Methods: The study included two scoping review studies based on searches of electronic databases as well as the Swedish dire

Sustained versus standard inflations during neonatal resuscitation to prevent mortality and improve respiratory outcomes

Background: At birth, infants' lungs are fluid-filled. For newborns to have a successful transition, this fluid must be replaced by air to enable effective breathing. Some infants are judged to have inadequate breathing at birth and are resuscitated with positive pressure ventilation (PPV). Giving prolonged (sustained) inflations at the start of PPV may help clear lung fluid and establish gas volu

Solute transfer in on-line analytical flow-through dialyzers

Mass transfer in infinite parallel-plate dialyzers with co-flow between sample and detector streams is discussed for three different theoretical models. Analytical solutions with coupled diffusion and membrane transfer equations were obtained for plug flow in both channels. The finite-difference approximation method was used to obtain numerical solutions for a laminar-flow regime. Results obtained

Clonal Hematopoiesis and risk of atherosclerotic cardiovascular disease

BACKGROUND Clonal hematopoiesis of indeterminate potential (CHIP), which is defined as the presence of an expanded somatic blood-cell clone in persons without other hematologic abnormalities, is common among older persons and is associated with an increased risk of hematologic cancer. We previously found preliminary evidence for an association between CHIP and atherosclerotic cardiovascular diseas

Teachers’ Assessment and grading Practices in upper secondary Science Classrooms in Sweden : The Teachers’ and Students’ Perspectives

This dissertation acknowledges that accountability of educators for the grades they assign is a part of the foundation for a meritocratic society, based on fairness in judging merit and, therefore, in assigning grades. In this view, any grade obtained by any student must be both reliable and valid. This, in turn, implies that the process of assessment of students’ work on which the grade is based

Skydd för berättigade förväntningar i svensk förvaltningsrätt? – Negativ rättskraft, EU-rätt och styrning av förvaltningen

En grundläggande fråga i den allmänna förvaltningsrätten är var gränserna ska gå för möjligheten att ändra meddelade beslut. I svensk förvaltningsrätt har denna fråga traditionellt besvarats med hjälp av principer om (förvaltningsrättslig) negativ rättskraft. I EU-rätten har det däremot under inflytande av andra medlemsstaters rättstraditioner utvecklats en unionsrättslig princip om skydd för berä

High contrast sensitivity for visually guided flight control in bumblebees

Many insects rely on vision to find food, to return to their nest and to carefully control their flight between these two locations. The amount of information available to support these tasks is, in part, dictated by the spatial resolution and contrast sensitivity of their visual systems. Here, we investigate the absolute limits of these visual properties for visually guided position and speed con

En ny gudinna för en ny tid : Ovidius och Hersilias metamorfos

This article argues that the Roman poet Ovid in his Metamorphoses invented the apotheosis of Hersilia into the goddess Hora as a way to flatter the empress Livia. There are compelling parallels between the words used to describe Hersilia and Livia in Ovid’s poetry. Furthermore, Hersilia was, according to the legend, a Sabine woman who married Romulus, the founder of Rome. Livia was born into the C
