- Background: Due to advances in hip arthroscopy, the number of surgical procedures has increased dramatically. The diagnostic challenge in patients with longstanding hip and groin pain, as well as the increasing number of hip arthroscopies, may lead to a higher number of patients referred to tertiary care for consideration for surgery. Therefore, the aims were: 1) to describe the prevalence of hip-related groin pain in patients referred to tertiary care due to longstanding hip and groin pain; and 2) to compare patient characteristics and patient-reported outcomes for patients categorized as having hip-related groin pain and those with non-hip-related groin pain. Methods: Eighty-one patients referred to the Department of Orthopedics at Skåne University Hospital for longstanding hip and groin pain were consecutively included and categorized into hip-related groin pain or non-hip-related groin pain using diagnostic criteria based on current best evidence (clinical examination, radiological examination and intra-articular block injection). Patient characteristics (gender (%), age (years), BMI (kg/m2)), results from the Hip Sports Activity Scale (HSAS), the SF-36, the Copenhagen Hip and Groin Outcome Score (HAGOS), and pain distribution (pain manikin) were collected. Parametric and non-parametric statistics were used as appropriate for between-group analysis. Results: Thirty-three (47%) patients, (30% women, 70% men, p < 0.01), were categorized as having hip-related groin pain. The hip-related groin pain group had a higher activity level during adolescence (p = 0.013), and a higher pre-injury activity level (p = 0.034), compared to the non-hip-related groin pain group. No differences (mean difference (95% CI)) between hip-related groin pain and non-hip-related groin pain were observed for age (0 (- 4; 4)), BMI (- 1.75 (- 3.61; 0.12)), any HAGOS subscales (p ≥ 0.318), any SF-36 subscales (p ≥ 0.142) or pain distribution (p ≥ 0.201). Conclusions: Only half of the patients referred to tertiary care for long-standing hip and groin pain, who were predominantly men with a high activity level, had hip-related groin pain. Self-reported pain localization and distribution did not differ between patients with hip-related groin pain and those with non-hip-related groin pain, and both patient groups had poor perceived general health, and hip-related symptoms and function.

- Objectives: To compare physical impairments between patients with hip-related pain and those with non-hip-related groin pain, and to compare both patient groups with healthy controls. Design: Cross-sectional. Participants: Eighty-one hip and groin pain patients were consecutively included and categorized into having hip-related pain or non-hip-related groin pain. Twenty-eight healthy controls were recruited. Settings: Tertiary care. Main outcome measures: All participants performed physical impairment testing including hip ROM, muscle function, and functional tasks. An analysis of covariates was used for analysis between patients groups and controls. Results: Patients with hip-related pain showed reduced hip ROM in internal rotation compared to patients with non-hip-related groin pain and controls (p ≤ 0.026, d −0.65; −0.97). No differences in muscle function or performance in functional tasks were observed between patients with hip-related pain and those with non-hip-related groin pain (p ≥ 0.136, d 0.00; 0.68). Both patient groups had worse muscle function and worse performance in functional tasks compared to controls (p ≤ 0.048, d −0.67; −1.83). Conclusions: Both patients with and without hip-related pain had worse muscle function and worse performance in functional tasks compared to matched controls but no differences were observed between the patient groups. Only patients with hip-related pain had reduced ROM in internal rotation.

- Laboratory measurements in flotation pulps with different electrodes in parallel under conditions of varying pulp chemistry are reported for copper-lead separation. The redox potential as measured with a glassy-carbon electrode correlates better with the response of an oxygen probe, than the traditional Pt-foil redox electrode. The glassy-carbon electrode also behaves in a way that averages the responses of mineral electrodes of pyrite, galena, and to some extent chalcopyrite.

- Laboratory measurements with different electrodes in parallel under conditions of varying chemistry of the flotation pulp are reported for the case of Cu--Pb separation. It is found that the redox potential as measured with a glassy-carbon electrode correlates better with the response of an oxygen probe, than the traditional platinum-foil redox electrode. The glassy-C electrode also behaves in a way which averages the responses of mineral electrodes of pyrite, galena and, to some extent, chalcopyrite

Fast isolation of proteins from bioreactors using affinity chromatography techniques
- 2000

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purification of proteins from raw materials like fermentation broth and other biological sources usually involves several purification steps and is rather time consuming and expensive. This is a major concern in the production of many important protein products e.g. pharmaceuticals such as insulin and blood coagulation factors. One way to speed up the isolation of protein from particle-containing liquids is by the use of expanded bed adsorption. By a selective adsorption of the desired protein, it can be clarified from particles, concentrated and purified from many molecular impurities in one step. A new improved support material for the use in expanded bed adsorption was developed and is described in this thesis. It was shown to have excellent adsorption efficiency at flow rates higher than normally used today. The new, pelicular, matrix was used to capture antibodies from cell-containing fermentation broth. When particle-free samples are to be purified, a packed bed can be used. In an industrially relevant application, the isolation of factor VIII from clarified fermentation broth, the recently developed matrix material “superporous agarose” was employed. Compared to traditional agarose supports it showed considerably higher efficiency at increased flow rates. This was ascribed to the presence of superpores that allow intraparticle flow, which reduces the diffusion distances. In analyses of cell-containing samples small columns permeable to cells and cell debris are valuable tools. A miniaturised expanded bed column and a small superporous monolithic column were designed and used in experimental set-ups in which cell containing samples were analysed for e.g. IgG and glucose. When new support materials are developed it is important to be able to compare their performance with existing supports. The methods used in determining the efficiency of expanded beds were critically examined and found unsuitable when comparing beds of different degrees of expansion. Quantities specially modified for expanded bed evaluation were therefore developed.

- A superporous agarose matrix was compared with a corresponding homogenous matrix in the isolation of recombinant factor VIII SQ (r-VIII SQ) by immunoaffinity chromatography. As a reference, the commercially available Sepharose FastFlow, used for a similar purification in the industry, was also evaluated. Breakthrough curves are described for flows between 50 and 400 cm/h with pre-purified r-VIII SQ and with cell culture broth. The superporous gel gave the best performance and a 1000-fold purification was obtained in a one-step procedure. The superporous matrix made it possible to increase the throughput about four-fold, presumably due to its better mass transfer properties. The importance of the ligand distribution profile is discussed based upon immunofluorescence microscopy data.
