  • The dining experience: Do restaurants satisfy customer needs?
  • 2004
  • Ingår i: Food Service Technology. ; :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. - 0962-1067. ; 13:1, s. 90
  • 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: The 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.)

  • 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.

  • Preoperative oral carbohydrate treatment attenuates endogenous glucose release 3 days after surgery
  • 2004
  • Ingår i: Clin Nutr. - 0261-5614. ; 23:4, s. 733
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND & AIMS: Postoperative metabolism is characterised by insulin resistance and a negative whole-body nitrogen balance. Preoperative carbohydrate treatment reduces insulin resistance in the first day after surgery. We hypothesised that preoperative oral carbohydrate treatment attenuates insulin resistance and improves whole-body nitrogen balance 3 days after surgery.METHODS: Fourteen patients undergoing total hip replacement were double-blindly randomised to preoperative oral carbohydrate treatment (12.5%, 800 + 400 ml, n = 8) or placebo (n = 6). Glucose kinetics (6,6-D2-glucose), substrate utilisation (indirect calorimetry) and insulin sensitivity (hyperinsulinaemic-euglycaemic clamp) were measured preoperatively and on the third day after surgery. Nitrogen losses were monitored for 3 days after surgery. Values are mean (SEM). Analysis of variance (ANOVA) statistics were used.RESULTS: Endogenous glucose release during insulin infusion increased after surgery in the placebo group. Preoperative carbohydrate treatment, as compared to placebo, significantly attenuated postoperative endogenous glucose release (0.69 (0.07) vs. 1.21 (0.13)mg kg(-1) x min(-1), P < 0.01), while whole-body glucose disposal and nitrogen balance were similar between groups.CONCLUSIONS: While insulin resistance in the first day after surgery has previously been characterised by reduced glucose disposal, enhanced endogenous glucose release was the main component of postoperative insulin resistance on the third postoperative day. Preoperative carbohydrate treatment attenuated endogenous glucose release on the third postoperative day.

  • A comparative study of barrier membranes as graft protectors in the treatment of localized bone defects. An experimental study in a canine model.
  • 2004
  • Ingår i: Clinical oral implants research. - 0905-7161. ; 15:4, s. 435
  • Tidskriftsartikel (refereegranskat)abstract
    • Guided bone regeneration is a predictable and well-documented surgical approach for the treatment of deficient alveolar ridges prior to endosseous implant placement. The purpose of this study was to compare a new resorbable membrane (GORE RESOLUT ADAPT Regenerative Membrane, i.e. 67% glycolide (PGA) : 33% trimethyline carbonate (TMC)) with Bio-Gide®, a resorbable collagen membrane. Five canines were used in the study. Three saddle-type osseous defects were created bilaterally in edentulous areas of the mandible. The defects were filled with assayed, canine demineralized freeze-dried bone (DFDB) in a thermoplastic gelatin matrix. Using a randomized block design, four sites were covered with PGA : TMC membranes of four different porosities, one site was covered with a collagen membrane and one site consisted of DFDB alone (control). At 3 months, the animals were euthanized and the mandibles were removed en bloc for laboratory processing. A total of 30 sites were reviewed microradiographically and underwent histomorphometric analysis for bone regeneration, soft tissue presence and remaining graft material. All sites exhibited uneventful healing. A significantly higher percentage of bone regeneration was seen in the sites protected by the PGA : TMC membrane. A higher component of soft tissue was visible beneath the collagen membrane as compared with the PGA : TMC membrane. The control sites exhibited noticeable deformation of the regenerated bone secondary to collapse of the overlying periosteum. The authors conclude that the PGA : TMC membrane protected the DFDB-filled defect and allowed a greater amount of bone regeneration than the defect protected by the collagen membrane or the control.
