Uptake of Active Surveillance for Very-Low-Risk Prostate Cancer in Sweden

Importance: Active surveillance is an important option to reduce prostate cancer overtreatment, but it remains underutilized in many countries. Models from the United States show that greater use of active surveillance is important for prostate cancer screening to be cost-effective.Objectives: To perform an up-to-date, nationwide, population-based study on use of active surveillance for localized

Myringoplasty Outcomes From the Swedish National Quality Registry

Objectives/Hypothesis: Data from patients registered for myringoplasty during 2002 to 2012 in the Swedish National Quality Registry for Myringoplasty. Study Design: Both conventional myringoplasty and fat-graft techniques were used aimed at healing the tympanic membrane in noninfected ears. Methods: Analysis was performed on data in a national database collected from 32 ear, nose, and throat clini

Identification of new susceptibility loci for type 2 diabetes and shared etiological pathways with coronary heart disease

To evaluate the shared genetic etiology of type 2 diabetes (T2D) and coronary heart disease (CHD), we conducted a genome-wide, multi-ancestry study of genetic variation for both diseases in up to 265,678 subjects for T2D and 260,365 subjects for CHD. We identify 16 previously unreported loci for T2D and 1 locus for CHD, including a new T2D association at a missense variant in HLADRB5 (odds ratio (

Directed Self-Assembly of Polarizable Ellipsoids in an External Electric Field

The interplay between shape anisotropy and directed long-range interactions enables the self-assembly of complex colloidal structures. As a recent highlight, ellipsoidal particles polarized in an external electric field were observed to associate into well-defined tubular structures. In this study, we systematically investigate such directed self-assembly using Monte Carlo simulations of a two-poi

Jamming and overpacking fuzzy microgels: Deformation, interpenetration, and compression

Tuning the solubility of fuzzy polymer microgels by external triggers, such as temperature or pH, provides a unique mechanism for controlling the porosity and size of colloidal particles on the nanoscale. As a consequence, these smart microgel particles are being considered for applications ranging from viscosity modifiers and sensing to drug delivery and as models for the glass and the jamming tr

Association between betel nut consumption and folate deficiency among pregnant women in rural Bangladesh

Background: Betel nut (BN) or areca nut (AN) chewing habits on its own or with other ingredients including chewing tobacco are highly prevalent in many South East Asian countries as well as among the migrants from these countries residing around the world. The major alkaloid arecoline in the BN has been found to carcinogenic and to be associated with a range of health risks, including negative eff

Effects of surgery and propofol-remifentanil total intravenous anesthesia on cerebrospinal fluid biomarkers of inflammation, Alzheimer's disease, and neuronal injury in humans : A cohort study

Background: Surgery and anesthesia have been linked to postoperative cognitive disturbance and increased risk of Alzheimer's disease. It is not clear by which mechanisms this increased risk for cognitive disease is mediated. Further, amyloid β production has been suggested to depend on the sleep-wake cycle and neuronal activity. The aim of the present study was to examine if cerebrospinal fluid (C

Function and flexibility of object exploration in kea and new caledonian crows

A range of non-human animals frequently manipulate and explore objects in their environment, which may enable them to learn about physical properties and potentially form more abstract concepts of properties such as weight and rigidity. Whether animals can apply the information learned during their exploration to solve novel problems, however, and whether they actually change their exploratory beh

Atrophy of the posterior subiculum is associated with memory impairment, Tau- and Aβ pathology in non-demented individuals

Alzheimer's disease (AD) is associated with atrophy of the cornu ammonis (CA) 1 and the subiculum subfield of the hippocampus (HC), and with deficits in episodic memory and spatial orientation. These deficits are mainly associated with the functionality of the posterior HC. We therefore hypothesized that key AD pathologies, i.e., β-amyloid and tau pathology would be particularly associated with th

Non-local Thermodynamic Equilibrium Stellar Spectroscopy with 1D and 〈3〉 Models. I. Methods and Application to Magnesium Abundances in Standard Stars

We determine Mg abundances in six Gaia benchmark stars using theoretical one-dimensional (1D) hydrostatic model atmospheres, as well as temporally and spatially averaged three-dimensional (〈3D〉) model atmospheres. The stars cover a range of Teff from 4700 to 6500 K, log g from 1.6 to 4.4 dex, and [Fe H] from -3.0 dex to solar. Spectrum synthesis calculations are performed in local thermodynamic eq

Non-local Thermodynamic Equilibrium Stellar Spectroscopy with 1D and 3D Models. II. Chemical Properties of the Galactic Metal-poor Disk and the Halo

From exploratory studies and theoretical expectations it is known that simplifying approximations in spectroscopic analysis (local thermodynamic equilibrium (LTE), 1D) lead to systematic biases of stellar parameters and abundances. These biases depend strongly on surface gravity, temperature and, in particular, for LTE versus non-LTE (NLTE), on metallicity of the stars. Here we analyze the [Mg/Fe]

Type 2 diabetes, adiposity and cancer morbidity and mortality risk taking into account competing risk of noncancer deaths in a prospective cohort setting

Type 2 diabetes (T2D) and adiposity associate with increased risk of several cancers, but the impact of competing risk of noncancer deaths on these associations is not known. We prospectively examined participants in the Malmö Diet and Cancer Study aged 44–73 years with no history of cancer at baseline (n = 26,953, 43% men). T2D was ascertained at baseline and during follow-up, and body mass index

Dissociative Experiences and Trauma Exposure Among Newly Arrived and Settled Young War Refugees

War-traumatized refugee adolescents are a vulnerable and understudied group. This study of two different groups of war-traumatized youth (N = 77) resettled in Sweden (newly arrived refugee adolescents, n = 42, 13–19 years, and settled students with childhood war experiences, n = 35, 11–18 years) evaluated their war experiences, refugee journey, general trauma exposure, posttraumatic stress symptom

All-seeing giants and blindfolded dwarfs: On information-asymmetries on data-driven markets

The objective of this chapter is to contribute to the understanding of the growth of this global data-driven market ecology, mainly in order to pinpoint important regulatory challenges, where individual choice and agency, as well as competition, seem undermined. Truly, this development holds many promises for new innovation, some more disruptive than others, but also poses challenges that in this

Solar-powered ventilation of African termite mounds

How termite mounds function to facilitate climate control is still only partially understood. Recent experimental evidence in the mounds of a single species, the south Asian termite Odontotermes obesus, suggests that the daily oscillations of radiant heating associated with diurnal insolation patterns drive convective flow within them. How general this mechanism is remains unknown. To probe this,

Administration of low-dose combination anti-CTLA4, anti-CD137, and anti-OX40 into murine tumor or proximal to the tumor draining lymph node induces systemic tumor regression

The delivery of immunomodulators directly into the tumor potentially harnesses the existing antigen, tumor-specific infiltrating lymphocytes, and antigen presenting cells. This can confer specificity and generate a potent systemic anti-tumor immune response with lower doses and less toxicity compared to systemic administration, in effect an in situ vaccine. Here, we test this concept using the nov

The cell wall composition of Norway spruce earlywood and latewood revisited

It is well known that the xylem of gymnosperm trees consists mainly of tracheids and that the dimensions of these cells change over the growth season in temperate regions. When looking at a micrograph of a cross section of a growth ring, it can be seen that early in the season tracheids have larger radial diameters and thin walls, while tracheids formed later in the growth season have smaller radi

Wood-water interactions in brown-rot decayed wood characterized by Low-Field Nuclear Magnetic Resonance (LFNMR)

It is a trivial fact that water is needed for decay of wood by brown rot fungi, but when this is looked at in more detail, there are several fundamental questions concerning water and decay that are not solved. The purpose of this study is to study how the wood-water interaction is changed during degradation of brown-rot fungi of Norway spruce (Picea abies (L) Karst.) grown at two different parts
