Study design:Observational study.Objectives:Thoraco-abdominal endovascular aortic aneurysm repair (TAEVAR) can be used to treat patients with extensive and complex aortic disease, however, at the risk of spinal cord ischemia (SCI). The aim of this follow-up study was to evaluate the life satisfaction in patients with SCI after TAEVAR.Setting:Among 83 patients undergoing TAEVAR between 2009 and 201
Objective: We sought to examine changes in regional and sex disparities in stunting, thinness, and overweight among Chinese school-aged children from 1985 to 2014. Methods: We analyzed data on 1,489,953 children aged 7–18 years in the Chinese National Survey on Students’ Constitution and Health. Stunting, thinness, and overweight were defined according to WHO anthropomorphic definitions. After adj
Background: Measuring the patients’ experience of care at an outpatient clinic can provide feedback about the quality of health care and if needed, can be support for quality improvements. To date, there is no patient reported experience measurement (PREM) developed targeting patients at the pulmonary arterial hypertension (PAH) outpatient clinics. Therefore, the aim was to develop and evaluate th
Benthic macroinvertebrates are part of a complex network of interactions. The spatial and temporal scales of the processes that form the basis for these interactions have traditionally restricted their empirical investigation. The first chapter of the manuscript attempts a review of the modelling tools that have been employed for the study of the marine benthos.The implementation of a mechanistic
Background: Comorbidity impacts overall survival amongst patients with diffuse large B-cell lymphoma (DLBCL). However, associations of comorbidity with lymphoma characteristics, treatment selection and lymphoma-specific mortality are less well known. Objective: To examine the impact of comorbidity on DLBCL characteristics, treatment intent and cause of death. Methods: We identified 3905 adult pati
Using optimality perspectives is now regarded as an essential way of analysing and understanding adaptations and behavioural strategies in bird migration. Optimization analyses in bird migration research have diversified greatly during the two recent decades with respect to methods used as well as to topics addressed. Methods range from simple analytical and geometric models to more complex modeli
Objective Neuropsychiatric events occur unpredictably in systemic lupus erythematosus (SLE) and most biomarker associations remain to be prospectively validated. This study examined a disease inception cohort of 1047 SLE patients to determine which autoantibodies at enrolment predicted subsequent neuropsychiatric events. Methods Patients with a recent SLE diagnosis were assessed prospectively for
Background and purpose Adequate depth of cement penetration and cement mantle thickness is important for the durability of cemented cups. A flanged cup, as opposed to unflanged, has been suggested to give a more uniform cement mantle and superior cement pressurization, thus improving the depth of cement penetration. This hypothesis was tested experimentally. Materials and methods The same cup desi
The purpose of this research was to investigate the potentiality of the Chinese market for olive oil and to assess how accessible China is for in particular small & medium sized companies in order to take the initiative on the market. The research departs from the CAP subsidy reforming European olive oil sector with 2,5 million producers on their way to a less trade distorted and more export m
The legal controversy on ''patents on life'' is not new but in the last two decades, we have seen the debate be intensified. Although patents on biological material have been allowed in the United States since the emergence of Diamond v. Chakrabarty in 1980, it was not until scientists at the National Institute of Health tried to patent thousands of gene fragments in the early nine
Detta examensarbete var en del i ett forskningsprojekt som utfördes vid avdelningen för maskinkonstruktion vid Lunds tekniska högskola och gick ut på att studera hur metodiken kring produktutveckling används hos ett antal företag i praktiken och jämföra detta med metodiken från litteraturen och det som lärs ut vid Lunds tekniska högskola, för att identifiera brister i modellerna och fungera som etThis Master´s Thesis is part of a larger research project carried out at the Division of Machine Design, Department of Design Science, LTH, and is about studying the product development methodologies applied in the industry and compare these to the methodologies described in the literature and taught at LTH. The first part of the assignment consisted in studying the existing methodologies about pr
Background: Software ecosystems emerged as means for several actors to jointly provide more value to the market than any of them can do on its own. Recently, software ecosystems are more often used to support the development of hardware-dependent solutions. Objectives: This work aims at studying barriers and bridges to participation in an ecosystem with substantial hardware dependencies. Method: W
Assessment of the long-term safety and efficacy of liquid inhaled insulin via AERx((R)) insulin Diabetes Management System (iDMS) in a basal/bolus treatment regimen of adults with Type 1 diabetes. Patients were randomized 2 : 1 to prandial inhaled (n = 205) or subcutaneous (s.c.) (n = 99) insulin, plus one/two daily injections of neutral protamine Hagedorn (NPH) insulin for 12 months. The primary
Beamforming is an important feature of 60 GHz communications. We present an analysis of the influence of beamforming in indoor ultrawideband radio channels measured in the mm-wave 60 GHz band. The performance of narrowband and wideband direction-based beamformers is investigated in terms of improving channel metrics such as the delay spread, excess delay, and the signal-to-noise ratio (SNR). The p
The aim of this study was to describe the types and extent of eating difficulties, the need for assistance when eating, the nutritional status and pressure ulcers in consecutive patients (n = 162) admitted for stroke rehabilitation over a period of 1 year. Structured observations and assessments of eating, nutritional status (subjective global assessment of nutritional status), pressure ulcers and
Digital image correlation (DIC) can measure full-field surface strains during mechanical testing of hard and soft tissues. When compared to traditional methods, such as strain gauges, DIC offers larger validation data (similar to 50,000 points) for, e.g., finite element models. Our main aim was to evaluate the repeatability of surface strain measurements with DIC during compressive testing of comp
Survival after childhood cancer has improved substantially over recent decades. Although cancer in childhood is rare increasingly effective treatments have led to a growing number of long-term survivors. It is estimated that there are between 300,000 and 500,000 childhood cancer survivors in Europe. Such good survival prospects raise important questions relating to late effects of treatment for ca
