  • The dining experience : do restaurants satisfy customer needs?
  • 2004
  • Ingår i: Food Service Technology. - 1471-5732. ; 4:4, s. 171-177
  • Tidskriftsartikel (refereegranskat)abstract
    • This is an exploratory paper where the main idea is to develop an analysis of dining as a multidimensional experience. In order to assess the relative importance of various aspects of restaurant services, customers were asked to estimate their willingness to pay for six aspects of the dining experience: food, service, fine cuisine, restaurant interior, good company and other customers. Customers were asked to evaluate an ideal restaurant experience as well as their latest restaurant experience. Thus the actual evaluation could be compared with an ideal value to explore where restaurants have opportunities to enhance customers’ restaurant experiences. Results clearly indicate that social needs are important for customers at evening restaurants whereas physiological needs dominate for customers at lunch restaurants.

  • Older patients with chronic heart failure within Swedish community health care : a record review of nursing assessments and interventions
  • 2004
  • Ingår i: Journal of Clinical Nursing. - Oxon, United Kingdom : Blackwell Publishing. - 0962-1067. ; 13:1, s. 90-6
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Older patients with chronic heart failure constitute a large group within community home care that is at high risk for re-hospitalization. However, hospital readmission can be prevented if early signs of deterioration are recognized and proper interventions applied.Aims and objectives: The aim of the study was to audit nursing care for older chronic heart failure patients within the Swedish community health care system.Design: The study adopted a retrospective descriptive design.Methods: In a Swedish urban municipality nursing documentation from 161 records on patients diagnosed with chronic heart failure was collected retrospectively from community nursing home care units. Patient records were reviewed for characteristics of nursing care and assessed for comprehensiveness in recording.Results: The main results showed that medical care of patients with chronic heart failure was poorly recorded, making it possible only to follow fragments of the care process. The nursing notes showed poor adherence to current clinical guidelines. Only 12% of the records contained notes on patients' body weight and only 4% noted patients' knowledge about chronic heart failure. When interventions did occur, they largely consisted of drug administration.Conclusions: The findings revealed flaws in the recording of specific assessment and interventions as well as poor adherence to current international clinical guidelines.Relevance to clinical practice: Supportive guidelines available at the point of care are needed to enhance proper community-based home health care for older patients with chronic heart failure.

  • The phenomena of participation and non-participation in health care : experiences of patients attending a nurse-led clinic for chronic heart failure
  • 2004
  • Ingår i: European Journal of Cardiovascular Nursing. - 1474-5151. ; 3:3, s. 239-246
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Patient participation is stressed in the health care acts of many western countries yet a common definition of the concept is lacking. The understanding of experiences of patients with chronic heart failure (CHF) who attend nurse-led specialist clinics, a form of care suggested as beneficiary to this group, may promote a better understanding of participation. Aim: To investigate the meanings of participation and non-participation as experienced by patients living with CHF. Methods: Narrative interviews analysed in the phenomenological hermeneutic tradition inspired by Ricoeur where the interpretation is made in the hermeneutic circle, explaining and understanding the experienced phenomena. Findings: Participation was experienced as to “be confident”, “comprehend” and “seek and maintain a sense of control”. Non-participation was experienced as to “not understand”, “not be in control”, “lack a relationship” and “not be accountable”. The findings indicate that the experiences of participation and non-participation can change over time and phases of the disease and treatment. Conclusion: The study suggests an extended view on the concept of participation. Patients' experiences of participation in health care can vary and should therefore be an issue for dialogue between nurses and patients with CHF in nurse-led specialist clinics.

  • Improved retention and bone-tolmplant contact with fluoride-modified titanium implants.
  • 2004
  • Ingår i: International Journal of Oral & Maxillofacial Implants. - 0882-2786. ; 19:5, s. 659-66
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: The purpose of the present study was to investigate whether a fluoride modification of the titanium surface would have an effect on bone response after implantation. Materials and Methods: Titanium-oxide–blasted titanium implants with and without fluoride modification were investigated in a rabbit tibia model. Quantitative analysis of surface roughness, biomechanical interlocking, and in vivo tissue reactions in rabbit bone at 1 and 3 months after placement were compared. Results: The fluoride-modified test implants had a slightly smoother surface (Sa: 0.91 ± 0.14 µm) than the unmodified control implants (Sa: 1.12 ± 0.24 µm). Significantly higher removal torque values (85 ± 16 Ncm vs 54 ± 12 Ncm) and shear strength between bone and implants (23 ± 9 N/mm2 vs 15 ± 5 N/mm2) were measured for the fluoride-modified implants after 3 months. The histomorphometric evaluations demonstrated higher bone-to-implant contact for test implants at 1 month (35% ± 14% vs 26% ± 8%) and 3 months (39% ± 11% vs 31% ± 6%) after placement. Discussion: Implant surface modification with fluoride may result in morphologic and physiochemical phenomena that are of significance for the bone response. Another possible explanation for the findings in the present study is that a surface modification changes the surface chemical structures to be more suitable for bone bonding. Conclusion: Based on the biomechanical and histomorphometric data, the fluoride-modified titanium implants demonstrated a firmer bone anchorage than the unmodified titanium implants. These implants achieved greater bone integration than unmodified titanium implants after a shorter healing time. (More than 50 references.)

  • Saproxylic beetles in natural and man-made deciduous high stumps retained for conservation
  • 2004
  • Ingår i: Biological Conservation. ; 118:2, s. 163-173
  • Tidskriftsartikel (refereegranskat)abstract
    • Intensive forest management in Scandinavia has decreased the amount of dead wood required by saproxylic (wood-living) organisms. To reduce this problem, some dead wood is now retained during forest operations, often in the form of man-made high stumps (ca. 4 m high). Most often these stumps are cut with a harvester, although the stumps in this study were made with explosives. The aims of this study were to determine whether such stumps of aspen (Populus tremula) and birch (Betula spp.) could be used by red-listed saproxylic beetles (Coleoptera), and to examine how the fauna of man-made high stumps differs from that of natural stumps. We also studied how tree species, sun-exposure, stage of decay and trunk diameter influenced the fauna. In 169 samples of bark from high stumps 116 saproxylic species were found, of which 21 were red-listed. Many species, including red-listed ones, were more associated with man-made stumps than with natural stumps. However, in total, more species were found in the natural than in the man-made stumps. This is probably because man-made stumps provide a more homogeneous type of wood substrate than natural ones. Among the other variables the difference between aspen and birch was the most important. We conclude that man-made high stumps are valuable habitats for many saproxylic beetle species.

  • Dietary acrylamide and risk of renal cell cancer
  • 2004
  • Ingår i: International Journal of Cancer. - Hoboken, USA : John Wiley & Sons. - 0020-7136. - 0020-7136 (Print) 0020-7136 (Linking) ; 109:5, s. 774-776

    • The detection of acrylamide, classified as a probable human carcinogen, in commonly consumed foods created public health alarm. Thus far, only 2 epidemiologic studies have examined the effect of dietary acrylamide on cancer risk. Presently, we reanalyzed data from a large population-based Swedish case-control study of renal cell cancer. Food frequency data were linked with national food databases on acrylamide content, and daily acrylamide intake was estimated for participants. The risk of renal cell cancer was evaluated for intake of food items with elevated acrylamide levels and for total daily acrylamide dose. Adjusting for potential confounders, there was no evidence that food items with elevated acrylamide, including coffee (OR(highest vs. lowest quartile) = 0.7; 95% CI = 0.4-1.1), crisp breads (OR(highest vs. lowest quartile) = 1.0; 95% CI = 0.6-1.6) and fried potatoes (OR(highest vs. lowest quartile) = 1.1; 95% CI = 0.7-1.7), were associated with a higher risk of renal cell cancer risk. Furthermore, there was no association between estimated daily acrylamide intake through diet and cancer risk (OR(highest vs. lowest quartile) = 1.1; 95% CI = 0.7-1.8; p for trend = 0.8). The results of this study are in line with the 2 previous studies examining dietary acrylamide and suggest there is no association between dietary acrylamide and risk of renal cell cancer.

  • Hydroxyapatite and carbon coatings for fixation of unloaded titanium implants
  • 2004
  • Ingår i: Journal of Long-Term Effects of Medical Implants. - 1050-6934. ; 14:6, s. 443-454
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to investigate the interaction between bone and pure titanium, titanium coated with hydroxyapatite (HA), and titanium coated with carbon in a rat femur model.In 25 rats, the medullary cavity of both femurs was entered by an awl from the trochanteric area. With steel burrs it was successively reamed to a diameter of 2.0 mm. Nails with a diameter of 2.0 mm and with a length of 34 mm were inserted in a random manner; either a pure titanium nail, a titanium nail entirely plasma-sprayed with a 75−100—μm layer of HA or a titanium nail coated with 2−10-μm carbon. The surface roughness of the pure titanium was characterized by Ra 2.6 μm and Rt 22 μm. Ra of HA was 7.5 μm and Rt 52 μm, and of carbon Ra was 0.4 μm and Rt 4.0 μm. Twelve rats were randomized to a follow up of 8 weeks, and the remaining 13 rats were followed for 16 weeks. At sacrifice both femora were dissected free from soft tissues and then immersed in fixative. A specimen slice of about 5 mm thickness was prepared from the subtrochanteric region with a water-cooled band-saw. Sample preparation for un-decalcified tissue followed the internal guidelines at the laboratories of Biomaterials/Handicap Research. At 8 weeks the median bone bonding contact of the implants was 43% (range 0−74) in the titanium group, 39% (0−75) in the HA group, and 3% (0−59) in the carbon group. At 16 weeks the corresponding figures were 58% (0−78) in the titanium group, 51% (15−75) in the HA group, and 8% (0−79) in the carbon group. In conclusion, we found great variability in bone bonding contact. In general, carbon-coated nails had reduced bone bonding contact both at 8 and at 16 weeks as compared to pure titanium or titanium coated with hydroxyapatite.

  • Audiological findings in Usher syndrome types IIa and II (non-IIa).
  • 2004
  • Ingår i: International journal of audiology. - 1499-2027. ; 43:3, s. 136-43
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim was to define the natural history of hearing lossin Usher syndrome type IIa compared to non-IIa. Peoplewith Usher syndrome type II show moderate-to-severehearing loss, normal balance and retinitis pigmentosa.Several genes cause Usher syndrome type II. Our subjectsformed two genetic groups: (1) subjects with Usher syndrometype IIa with a mutation and/or linkage to theUsher IIa gene; (2) subjects with the Usher II phenotypewith no mutation and/or linkage to the Usher IIa gene.Four hundred and two audiograms of 80 Usher IIa subjectswere compared with 435 audiograms of 87 non-IIasubjects. Serial audiograms with intervals of ≥5 yearswere examined for progression in 109 individuals. Thosewith Usher syndrome type IIa had significantly worsehearing thresholds than those with non-IIa Usher syndromeafter the second decade. The hearing loss in Ushersyndrome type IIa was found to be more progressive, andthe progression started earlier than in non-IIa Usher syndrome.This suggests an auditory phenotype for Ushersyndrome type IIa that is different from that of other typesof Usher syndrome II. Thus, this is to our knowledgeone of the first studies showing a genotype-phenotypeauditory correlation.
