Intermediate-Term Outcome After Distal Radius Fracture in Patients With Poor Outcome at 1 Year : A Register Study With a 2- to 12-Year Follow-Up

Purpose: Most patients recover well from a distal radius fracture (DRF). However, approximately one-fifth have severe disability after 1 year when evaluated using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. In the present study, we evaluated this subgroup of patients in our register with an inferior outcome. We hypothesized that the patient-reported outcome would improve

The impact of governance on teaching excellence in academic microcultures

Torgny Roxå and Katarina Mårtensson note that the achievement of teaching excellence is intrinsically linked with organizational structures that recognize and reward excellence. They suggest that understanding organizational structures is important in the extent to which they have the potential to either promote or jeopardize excellence. Using the three principles for governance – collegial, manag

Heritopia : World Heritage and modernity

Heritopia explores the multiple meanings of the past in the present, using the famous temples of Abu Simbel and other World Heritage sites as points of departure. It employs three perspectives in its attempt to understand and explain both past and present: the truth of knowledge, the beauties of narrative, and ethical demands. Crisis theories are rejected as nostalgic expressions of contemporary s

En tid utan sammanhang

Ett antal rapporter under senare år har uppmärksammat oss på hur farlig ensamhet är för hälsan. Enligt vissa studier är den till och med farligare än rökning. Särskilt utsatta är äldre. Larmrapporterna har lett till flera debattinlägg, där man menar att politikerna måste ta ett större ansvar. Vissa pekar på Storbritannien, där man har inrättat en särskild ensamhetsminister. Men är ensamheten verkl

Agriculture and animal production have a great environmental impact, which is steadily growing. In a previous article, we highlighted how biodiversity is vital for agricultural production, emphasizing the role of animal pollinators. Here, we discuss the different dimensions of food security and the key role of our food choices in the cities to drive land use in rural areas and minimize the environ

Detailed Fluctuation Relation for Arbitrary Measurement and Feedback Schemes

Fluctuation relations are powerful equalities that hold far from equilibrium. However, the standard approach to include measurement and feedback schemes may become inapplicable in certain situations, including continuous measurements, precise measurements of continuous variables, and feedback induced irreversibility. Here we overcome these shortcomings by providing a recipe for producing detailed

Large variations in iron input to an oligotrophic Baltic Sea estuary : Impact on sedimentary phosphorus burial

Estuarine sediments are key sites for removal of phosphorus (P) from rivers and the open sea. Vivianite, an Fe(II)-P mineral, can act as a major sink for P in Fe-rich coastal sediments. In this study, we investigate the burial of P in the Öre Estuary in the northern Baltic Sea. We find much higher rates of P burial at our five study sites (up to ĝ1/4 0.145 molĝ€†mĝ'2ĝ€†yrĝ'1) when compa

Postpregnancy BMI in the Progression From Hypertensive Disorders of Pregnancy to Type 2 Diabetes

OBJECTIVE: To study the extent to which BMI after pregnancy adds to the elevated risk of postpregnancy type 2 diabetes in women with a history of hypertensive disorders of pregnancy (HDP) (preeclampsia or gestational hypertension).RESEARCH DESIGN AND METHODS: We used data from the Nurses' Health Study II, a prospective cohort study. In women aged 45-54 years without prior gestational diabetes mell

Heme induces endoplasmic reticulum stress (Hier stress) in human aortic smooth muscle cells

Accumulation of damaged or misfolded proteins resulted from oxidative protein modification induces endoplasmic reticulum (ER) stress by activating the pathways of unfolded protein response. In pathologic hemolytic conditions, extracellular free hemoglobin is submitted to rapid oxidation causing heme release. Resident cells of atherosclerotic lesions, after intraplaque hemorrhage, are exposed to he

Connecting the Greenland ice-core and U/Th timescales via cosmogenic radionuclides : Testing the synchroneity of Dansgaard-Oeschger events

During the last glacial period Northern Hemisphere climate was characterized by extreme and abrupt climate changes, so-called Dansgaard-Oeschger (DO) events. Most clearly observed as temperature changes in Greenland ice-core records, their climatic imprint was geographically widespread. However, the temporal relation between DO events in Greenland and other regions is uncertain due to the chronolo

α1-microglobulin protects against bleeding-induced oxidative damage in knee arthropathies

Knee injury increases the risk of developing knee osteoarthritis (OA). Recent evidence suggests involvement of oxidative stress induced by inflammation and bleeding in the joint. This study investigates the role in this process of α1-microglobulin (A1M), a plasma and tissue antioxidant protein with reducing function, and heme- and radical-binding properties. We studied matched knee synovial fluid

Lumped-parameter grey-box modelling of traction machines for low-speed operation

This paper presents a procedure to derive a thermal lumped-parameter grey-box model of an electric machine built for traction. The procedure includes experimental data logged under overload conditions for accurate temperature prediction at high currents, and features a relatively simple loss estimation approach. Validation of the model shows a good fit between measured and simulated results. Possi

Direct Conductor Cooling in Concentrated Windings

This paper presents and assesses the cooling integration of electrical machines with concentrated windings. A conventional coil in a concentrated winding with forced cooling applied on the exterior coil surfaces is replaced by an alternative solution where the coil is opened up in a laminar structure with the intention of the coolant fluid penetrating the coil and removing the interior heat. This

Cycling environmental perception in Beijing – A study of residents’ attitudes towards future cycling and car purchasing

This study focuses on three groups: cyclists, non-cyclists, and non-car owners and examines the significance of the perceived cycling environment, current travel behavior, urban form and socio-demographic variables for the respondents’ attitudes towards future cycling and car purchasing. The paper uses survey data (N = 1427) collected in eight Beijing neighborhoods. The analysis is carried out by
