Determinants of health-related quality of life in a multinational systemic sclerosis inception cohort

OBJECTIVES: To evaluate health-related quality of life (HRQoL) and its determinants in a systemic sclerosis (SSc) multinational inception cohort. We performed a meta-analysis of data from individual countries, and compared the meta-analysis to individual country results by pooling data from each of the countries.METHODS: SSc patients within 2 years of disease onset were recruited from 5 countries

Sustainable development of science and scientists: academic training in life science labs

Academic training, where senior scientists transfer their knowledge and skills to junior scientists through apprenticeship, plays a crucial role in the development of scientists. This study focuses on two aspects of academic training, autonomy and exploration, to investigate how different modes of training are incentivized and how they affect junior scientists’ performance and career prospects. Dr

Gender differences in early systemic sclerosis patients : a report from the EULAR scleroderma trials and research group (EUSTAR) database

METHODS: A cross-sectional analysis of the prospective EULAR Scleroderma Trial and Research database (EUSTAR) was performed. Patients fulfilling preliminary ACR 1980 classification criteria for SSc, with less than 3 years from the first non-Raynaud's symptom at first entry, were selected. A group of patients with less than 3 years from the first SSc symptom, including Raynaud's phenomenon, was als

Commemorating Humayun: Emperor Akbar, the Akbarnama and the tomb of Humayun (ca. 1570–1605)

This essay discusses the commemoration of the Mughal emperor Humayun (r. 1530–40, 1555–56) by his son Akbar (r. 1556–1605), focusing both on Akbar’s practice of visiting the tomb and the way in which these tomb-visits were dealt with by contemporaneous chroniclers. The article shows how Akbar’s chief ideologist, Abu’l Fazl, misrepresented Akbar’s history of visiting his father’s tomb, predating th

Safavid Cousins on the Verge of Extinction : Dynastic Centralization in Central Asia and the Bahrāmī Collateral Line (1517-1593)

The Bahrāmī Safavids, a relatively unknown collateral branch of the Safavid dynasty, active in Iran from 1517 to 1593, played a crucial role in dynastic developments in Safavid Iran. This essay examines the dynastic developments of the Safavid rulers and their contemporaries to argue that they embarked on a process of dynastic centralization, presenting themselves increasingly as the only holder

Being Nassau : Nassau family histories and Dutch national discourse from 1541 to 1616

William I of Nassau, Prince of Orange, and his sons Maurice and Frederick Henry were seen in their own time as the protectors of the new Dutch nation. As such, they play a significant role in the formation of a Dutch national identity. This essay addresses the question in what measure this sentiment was returned: did the Nassaus feel Dutch? An analysis of dynastic arguments used in the Apology (15

A constant power capacitor charging structure for flicker mitigation in high power long pulse klystron modulators

In order to generate high voltage high pulsed power, klystron modulators necessarily contain at least one capacitor bank charging structure supplying the energy to be released during the pulse. Conventional charging structures are based on AC/DC front-end units typically based on diode rectifiers combined with on/off controlled power charging structures as a second stage, producing prohibitive lev

Zero average flux tracking algorithm for high frequency transformers in long pulse applications

High voltage long pulse klystron modulators typically use pulse transformers, where the length of the pulse dictates the size of the transformer. Recent advancements in power electronics applied to modulator technology, in order to facilitate multi-millisecond long pulse generation, instead suggests use of high frequency transformers in a high frequency pulse modulation/demodulation scheme, elimin

Predicting undetected glaucoma according to age and IOP : a prediction model developed from a primarily European-derived population

Purpose: To model prediction of undetected glaucoma in a predominantly white population, based on intraocular pressure (IOP) and subject age. Methods: In 1992–1997, a population screening for glaucoma was performed at Malmö University Hospital where individuals between 55–79 years of age (n = 46 614) living in Malmö, were invited to a free eye health examination. Recently examined patients were no

Altered asparagine and glutamate homeostasis precede coronary artery disease and type 2 diabetes

Context: Type 2 diabetes mellitus (T2DM) is accompanied by an increased risk for coronary artery disease (CAD), but the overlapping metabolic disturbances preceding both diseases are insufficiently described. Objective:Wehypothesized that alterations in metabolism occur years before clinical manifestation of T2DM and CAD and that these alterations are reflected in the plasma metabolome. We thus ai

Post-discharge use of assistive devices following hemiarthroplasty : comparison of fracture patients with or without hip precautions

Purpose: To describe which types of assistive devices prescribed and actually used, either due to precautions or due to true functional reasons, after hip fracture-related hemiarthroplasty. Materials and methods: About 394 patients cluster-randomized 2010–2014 at a university hospital. Control group with standard postoperative precautions to reduce dislocations, mandatory assistive devices and kne

Catch Me if You Can : Streptococcus pyogenes Complement Evasion Strategies

The human host has evolved elaborate protection mechanisms to prevent infection from the billions of microorganisms to which it host is exposed and is home. One of these systems, complement, is an evolutionary ancient arm of innate immunity essential for combatting bacterial infection. Complement permits the efficient labelling of bacteria with opsonins, supports phagocytosis, and facilitates phag

Climate Science for Policy? The knowledge politics of the IPCC after Copenhagen

Klimatförändringarna kommer att påverka ekosystem och samhällen över hela världen. Det är ett problem som kräver drastiska och omedelbara förändringar av vårt sätt att leva och av våra samhällsstrukturer, och därmed politiskt engagemang av aldrig tidigare skådat slag. Under de senaste 30 åren, sedan bildandet av Förenta Nationernas ramkonvention om klimatförändringar (Klimatkonventionen; UNFCCC) åThe rise of climate change as an issue of global concern has rested on scientific representation and understanding of the causes and impacts of, and responses to climatic change. The Intergovernmental Panel on Climate Change (IPCC), in particular, has been central to how climate change has become known as a global political problem. This thesis aims to critically examine the production, negotiatio
