Abstract Background Osteonecrosis (ON) is defined by the in situ death of bone cells, osteocytes, hematopoietic and fatty marrow precursor cells. Events and risk factors known to be associated with ON are femoral neck fracture, hip dislocation, slipped capital femoral epiphysis in children, humeral head fracture and insufficiency fractures in load-bearing joints. The etiology of non-traumatic ON

Background: In the nineties, the patients with inguinal hernias were exposed to several newly developed repair techniques using alloplastic mesh prosthesis. Although the scientific knowledge was limited, the new techniques were rapidly introduced due to surgical enthusiasm, but also by an eagerness to reduce the recurrence rate and to shorten the time to recovery. When the first study of this thes

This thesis addresses the application of hollow fiber liquid phase microextraction as a simple, efficient and environmentally friendly tool to study the fate of four common anti-inflammatory drugs (ketoprofen, naproxen, diclofenac and ibuprofen) during wastewater treatment. Initial experiments verified that this technique is applicable on aqueous as well as suspensions of solid samples, thus great

AbstractThe cycling of carbon in its gaseous, solid and dissolved forms is of central importance to ecosystem science, particularly, when the natural carbon cycle has been perturbed by human activity. Mathematical models are commonly used to asses and predict global and regional patterns of terrestrial carbon exchange. At the same time, processes operating on smaller (sub-grid) scales are usually

Energy use in buildings accounts for a significant proportion of the total energy use in many countries. While past and current buildings have solely been energy consumers, future buildings will, besides using less energy, also need to produce (part of ) the required energy on site with renewables. Solar energy is generally very suitable for producing this on-site renewable energy. Although solar

Case-control studies comprising telephone interviews for 333 cases of acute myeloid leukemia (AML), 226 cases of Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML), 330 cases of myelodysplastic syndromes (MDS), and matched controls were conducted. Information had to be obtained from next-of-kin much more often for cases (85%) than for controls (18%). Tobacco smoking was associated

Security in organizations is no longer just a matter of having locks and alarms; it is more like a question of different dimensions of rules, perceptions and actions. The focus must return to more interpersonal relationships in security issues instead of technically advanced equipment. In facing today’s challenges, the focus must be on more interpersonal relationships in security issues than on te

The number of vertebral fractures has increased during the last few decades.The increase could at least partly be explained by the increasing proportion of elderly in society since these fractures are more commonly found in elderly than in young individuals. Low bone mass and osteoporosis which are also partly related to aging are risk factors for fracture but both age and low bone mass are indepe

Helicobacter pylori is one of the most common infections in man. The infection is often acquired during childhood and usually results in a chronic life-long inflammation in the gastric mucosa. The aim of our studies was to investigate the association between H. pylori seropositivity and the development of gastric and oesophageal carcinomas. Nested case-control studies were performed in the Malmö P

The effects of increasing temperatures, in light of climate change, have been a well-studied topic during the past decades. However, aquatic ecosystems are also faced with additional challenges such as increasing water colour, known as “brownification”. Although we know that temperature and water colour will increase simultaneously this has been given little attention in ecological research. In th

The aim was to study some aspects of patients´ well-being, related to nutrition, activities of daily living and health related quality of life, when undergoing major gastrointestinal cancer surgery. Chart documentations (N=45) of patients undergoing subtotal pancreatectomy were studied, and showed the patients' well-being to be affected, although it was not possible to fully evaluate the results o

Tumour deposits are a prognostic factor for overall survival and distant metastasis in lymph node-negative colorectal cancer. However, the current TNM staging system does not account for the presence of tumour deposits in lymph node-positive colorectal cancer, or for the presence of multiple deposits. This study aimed to investigate the prognostic effect of tumour deposit count in patients with coBackgroundTumour deposits are a prognostic factor for overall survival and distant metastasis in lymph node-negative colorectal cancer.

Landslide risk assessments and environmental risk assessments are routinely carried out in many countries exposed to landslide hazards and/or contaminated soil hazards, but separately from each other. By combining results from different types of risk assessments and superimposing the results, possible multi-hazards may be revealed, which is not the case when the results are only displayed independ

Abstract The new role of built cultural heritage, as an economic asset for development strategies and the widened definition of built heritage as a concept-, explains today’s affluence of sites. These can only be guaranteed with sufficient heritage funding. Financers’ inducement to fund cultural heritage depends on that heritage’s current value estimation and only highly revered sites qualify fo
