Single Nucleotide Polymorphisms in Close Proximity to the Fibroblast Growth Factor 21 (FGF21) Gene Found to Be Associated with Sugar Intake in a Swedish Population

Hereditary mechanisms are partially responsible for individual differences in sensitivity to and the preference for sweet taste. The primary aim of this study was to examine the associations between 10 genetic variants and the intake of total sugar, added sugar, and sugars with sweet taste (i.e., monosaccharides and sucrose) in a middle-aged Swedish population. Two single nucleotide polymorphisms

Subcutaneous and submuscular transposition due to ulnar nerve entrapment at the elbow– Analyses of 43 primary and 44 revision cases

Objectives: Knowledge is scarce about the outcome of revision surgery for recurrent or persistent ulnar nerve entrapmentat the elbow (UNE). We studied the outcome of subcutaneous (SCT) and submuscular (SMT) ulnar nerve transpositionsdue to UNE, analyzing both primary and revision surgeries, aiming to identify predictors for revision surgery.Methods: All surgically treated UNE cases (2004-2008) at

alpha-synuclein: amyloid fibrils and interactions with lipid membranes

The second most common neurodegenerative disease, Parkinson’s disease, is linked with an amyloid forming protein, alpha-synuclein. Hallmarks of Parkinson’s disease are progressive loss of dopaminergic neurons and accumulation of intraneuronal inclusions termed Lewy bodies. Major components of Lewy bodies are amyloid fibrils formed by alpha-synuclein and various lipids and cell organelles. In this

Cerebrospinal Fluid Biomarker Levels as Markers for Nursing Home Placement and Survival Time in Alzheimer's Disease

BACKGROUND: Cerebrospinal fluid (CSF) biomarkers are associated with conversion from mild cognitive impairment to Alzheimer's disease (AD), but their predictive value for later end-points has been less evaluated with inconsistent results.OBJECTIVE: We investigated potential relationships between CSF amyloid-β1-42 (Aβ42), phosphorylated tau (P-tau), and total tau (T-tau) with time to nursing home p

Differences in Dementia Care Between Swedish-Born and Foreign-Born from Countries with Different Country Level Socioeconomic Position : A Nationwide Register-Based Study

BACKGROUND: With a growing elderly population worldwide, the prevalence of dementia is rapidly increasing. Studies from high income countries have shown that belonging to a minority ethnic group increases the risk of health disadvantages.OBJECTIVE: The aim of the present registry-based study was to identify potential differences in diagnostics, treatment, and care of individuals with dementia focu

The unhappy chaperone

Chaperones protect other proteins against misfolding and aggregation, a key requirement for maintaining biological function. Experimental observations of changes in solubility of amyloid proteins in the presence of certain chaperones are discussed here in terms of thermodynamic driving forces. We outline how chaperones can enhance amyloid solubility through the formation of heteromolecular aggrega

Drug use disorder and risk of incident and fatal prostate cancer among Swedish men : a nationwide epidemiological study

Purpose: Prostate cancer is the second most common cancer in men and a leading cause of cancer mortality worldwide. Men with drug use disorders (DUD) may potentially be at high risk for prostate cancer mortality because of delayed diagnosis and/or undertreatment. In this study, we aimed to investigate prostate cancer incidence, mortality, and stage at time of diagnosis among men with DUD compared

Stillbirth or neonatal death before 45 post-menstrual weeks in relation to gestational duration in pregnancies at 39 weeks of gestation or beyond : the impact of parity and body mass index. A national cohort study

Objective: To investigate the risk of stillbirth or neonatal death before 45 post-menstrual weeks in relation to gestational duration, stratified by body mass index (BMI) and parity. Design: Retrospective study. Setting: Data from the Swedish Medical Birth Register. Population: Singleton, cephalic births at between 39+0 and 42+2 weeks of gestation, 2005–2016 (n = 892 339). Methods: Relative risk r

Utilization of psychiatric services prior to suicide- a retrospective comparison of users with and without previous suicide attempts

INTRODUCTION: The aim was to investigate psychiatric health care utilization two years before death by suicide among individuals with previous suicide attempts (PSA) compared with those without (NSA).METHOD: A retrospective population-based cohort study was conducted including 484 individuals who died by suicide in Sweden in 2015 and were in contact with psychiatric services within the two years p

The heritability of doctor-diagnosed traumatic and degenerative meniscus tears

Objective: To estimate the genetic contribution to traumatic and degenerative meniscus tears for men and women across the lifespan. Methods: We linked the Swedish Twin Register with individual-level national healthcare data to form a 30-year, population-wide, longitudinal twin cohort. To study genetic contribution to meniscus tears, we estimated the heritability and familial risk using incident tr

Chiral Selectivity of Secondary Nucleation in Amyloid Fibril Propagation

Chirality is a fundamental feature of asymmetric molecules and of critical importance for intermolecular interactions. The growth of amyloid fibrils displays a strong enantioselectivity, which is manifested as elongation through the addition of monomers of the same, but not opposite, chirality as the parent aggregate. Here we ask whether also secondary nucleation on the surface of amyloid fibrils,

Type 2 diabetes burden among migrants in Europe : unravelling the causal pathways

European populations are ethnically and culturally diverse due to international migration. Evidence indicates large ethnic inequalities in the prevalence of type 2 diabetes. This review discusses the burden of type 2 diabetes and its related complications, and the potential explanatory mechanisms among migrants in Europe. The current available data suggest that the rate of type 2 diabetes is highe

Rapid and facile purification of apolipoprotein A-I from human plasma using thermoresponsive nanoparticles

Nanoparticles can be used to purify proteins from plasma. We report here the purification of apolipoprotein A-I (apoA-I) with high specificity from human plasma using copolymeric nanoparticles. We present an optimized protocol using 50:50 NiPAM:BAM copolymer nanoparticles with thermo-responsive properties as an affinity resin. Repeated pelleting and washing of nanoparticle-captured apoA-I is achie

Distinction of lymphoid and myeloid clonal hematopoiesis

Clonal hematopoiesis (CH) results from somatic genomic alterations that drive clonal expansion of blood cells. Somatic gene mutations associated with hematologic malignancies detected in hematopoietic cells of healthy individuals, referred to as CH of indeterminate potential (CHIP), have been associated with myeloid malignancies, while mosaic chromosomal alterations (mCAs) have been associated wit

Standardization of disaster risk management - Challenges and opportunities

This chapter discusses the question of whether increasing the level of standardization in a disaster risk management system will increase its effectiveness. Based on the results from several studies conducted in the context of the Swedish disaster risk management system, the authors argue that there are both positive and negative effects of increased standardization. More precisely, studies based

Should I Stay or Should I Go? Associations between Occupational Factors, Signs of Exhaustion, and the Intention to Change Workplace among Swedish Principals

A high turnover among principals may disrupt the continuity of leadership and negatively affect teachers and, by extension, the students. The aim was to investigate to what extent various work environment factors and signs of exhaustion were associated with reported intentions to change workplace among principals working in compulsory schools. A web-based questionnaire was administered twice, in 2
