    Perceptions of family planning among low-income men in Western Kenya: Original Article2009Inngår i: International Nursing Review, ISSN 0020-8132, E-ISSN 1466-7657, Vol. 56, nr 3, s. 340-345Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Men have rarely been involved in either receiving or providing information on sexuality, reproductive health or birth spacing. They have also been ignored or excluded in one way or the other from participating in many family planning programmes as family planning is viewed as a womans affair.

    Aim: To describe the perceptions of family planning among low-income men in Western Kenya. Methods: A qualitative study using focus group interviews and content analysis was conducted, with 64 men aged 15-54 years participating actively.

    Findings: Perceptions of family planning were manifold. For example, some perceived it as meaning having the number of children one is able to provide for. Most men knew about traditional and modern methods of birth control, although their knowledge was poor and misconceived. Modern methods were thought to give side effects, discouraging family planning. Low instances of family planning were also because of the fact that culturally, children are considered wealth. A law advocating family size limitation was regarded as necessary for the future.

    Conclusion: Mens perceptions of family planning are manifold. Their knowledge about contraception is poor and sometimes misconceived. Preferences regarding a childs gender are strong, thus attitudes and cultural beliefs that might hinder family planning have to be considered. A policy on male contraception and contraceptive services is seen as necessary.

    Implementation of computerized alcohol screening and advice in an emergency department - a nursing staff perspective2007Inngår i: Accident and Emergency Nursing, ISSN 0965-2302, E-ISSN 1532-9267, Vol. 15, nr 1Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Changes in attitudes towards alcohol prevention among nursing staff are evaluated after implementing an opportunistic computerized alcohol screening and intervention (e-SBI) at an emergency department. After having assessed the patients in the triage room the nurses asked patients to perform the e-SBI on a touch screen computer. Before the start of the project more than 60% of the nurses expected the patients to react negatively when asked about their alcohol habits. After one year of screening only 10% reported experience of negative reactions from the patients. More than 50% of the nurses found it easy or very easy to ask the patients to perform the e-SBI and more than 75% of the nurses agreed that the e-SBI did not affect their workload. The proportion of nurses who considered alcohol prevention to be part of their duties at the emergency department did not change (40%) after implementing the e-SBI. During the two-year study period, 1982 patients completed the e-SBI which constituted 10-20% of all patients between 16 and 70 years of age attending the department for a sub critical condition. The e-SBI seems to have better potential than ordinary alcohol screening and intervention for implementation into routine emergency departments due to its simplicity and low time consumption. © 2006 Elsevier Ltd.

    Blood flow measurements at different depths using photoplethysmography and laser Doppler techniques2009Inngår i: Skin research and technology, ISSN 0909-752X, E-ISSN 1600-0846, Vol. 15, nr 2, s. 139-147Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background/purpose: This study has evaluated a multi-parametric system combining laser Doppler flowmetry and photoplethysmography in a single probe for the simultaneous measurement of blood flow at different depths in the tissue. This system will be used to facilitate the understanding of pressure ulcer formation and in the evaluation of pressure ulcer mattresses.

    Methods: The blood flow in the tissue over the sacrum was measured before, during and after loading with 37.5 mmHg, respectively, 50.0 mmHg. The evaluation of the system consisted of one clinical part, and the other part focusing on the technicalities of the probe prototype.

    Results: An increase in blood flow while loading was the most common response, but when the blood flow decreased during loading it was most affected at the skin surface and the blood flow responses may be different due to depths of measurement. Reactive hyperaemia may occur more frequently in the superficial layers of the tissue.

    Conclusion: The study showed that the new system is satisfactory for measuring tissue blood flow at different depths. The laser Doppler complements the photoplethysmography, and further development of the system into a thin flexible probe with the ability to measure a larger area is required.

    Treatment of anaemia in inflammatory bowel disease with iron sucrose2004Inngår i: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 39, nr 5, s. 454-458Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Inflammatory bowel disease (IBD)-associated anaemia usually responds to intravenous iron. If not, additive treatment with erythropoietin has been proposed. The objective of the present retrospective study was to evaluate the effectiveness of treatment with iron sucrose alone. Methods: Sixty-one patients with IBD and anaemia (average haemoglobin 97 g/L) were treated with iron sucrose (iron dose 1.4 ± 0.5 g). The indications for iron sucrose were poor response and/or intolerance to oral iron. Treatment response was defined as an increase in haemoglobin of ≥20 g/L or to normal haemoglobin levels (>120 g/L). Two independent investigators retrospectively assessed laboratory variables, clinical findings, and concomitant medication. Results: Two patients were transferred to other hospitals after treatment and therefore could not be evaluated. Fifty-four of the remaining 59 patients (91%) responded within 12 weeks. Sixty percent of the patients had responded within 8 weeks. Five patients had no or only a partial response to iron sucrose of which three had prolonged gastrointestinal blood losses. Eight patients with normal or elevated levels of ferritin could be considered to have anaemia of chronic disease, and all of them responded to iron sucrose. During a follow-up period of 117 ± 85 (4-291) (mean ± s (standard deviation) (range)) weeks 19 patients (32%) needed at least one second course of iron sucrose because of recurrent disease. Conclusions: Anaemia associated with IBD can be successfully treated with intravenously administered iron sucrose, provided that bowel inflammation is treated adequately and enough iron is given. Treatment with iron sucrose is safe. Follow-up of haemoglobin and iron parameters to avoid further iron deficiency anaemia is recommended.

    Is a dissection balloon beneficial in bilateral, totally extraperitoneal, endoscopic hernioplasty? A randomized, prospective, multicenter study2001Inngår i: Surgical Laparoscopy, Endoscopy and Percutaneous Techniques, ISSN 1051-7200, E-ISSN 2331-2254, Vol. 11, nr 5, s. 322-326Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Laparoscopic hernioplasty has been criticized because of its technical complexity and increased costs. Disposable dissection balloons can be used to gain the initial working space in totally extraperitoneal endoscopic (TEP) hernioplasty, but this increases its cost. Forty-four men with bilateral, primary or recurrent inguinal hernias were randomized to undergo TEP with or without dissection balloon, There were two conversions to transabdominal preperitoneal hernioplasty, or open herniorrhaphy, in the group with balloon and four in the group without balloon. There was no difference in the postoperative morbidity or operation time between the two groups, and there were no major complications in either group. The recurrence rate was 4.3% in the group with the balloon and 7.1% in the group without the balloon. There were no statistically significant differences between the groups, Although our study population is too small to detect small differences between the groups, it seems that the use of a dissection balloon is not beneficial in a bilateral TEP.

    Thrombin generation and D-dimer concentrations in a patient cohort investigated for venous thromboembolism. Relations to venous thrombosis, factor V Leiden and prothrombin G20210A. The LIST study.2009Inngår i: Thrombosis Research, ISSN 0049-3848, E-ISSN 1879-2472, Vol. 124, nr 2, s. 178-84Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION: The present study evaluated possible relations between various markers of thrombin generation, D-dimer and venous thromboembolism in outpatients with and without the FV Leiden and the protrombin mutations. PATIENTS AND METHODS: Our cohort consisted of 98 patients with the FV Leiden and 15 with the prothrombin mutation and an equal number of age- and gender-matched controls. All subjects were investigated due to suspicion of venous thromboembolism and the diagnosis was objectively confirmed or refuted. RESULTS: We compared the D-dimer values and the thrombin generation markers among different patient groups (with/without thromboembolism, with/without genetic factors, gender-linked). The only statistically significant difference noted was prolonged time both for the initiation and termination of thrombin generation in patients with thrombosis. This applied to controls and to patients heterozygous for the FV Leiden. Additionally, the D-dimer values were elevated in patients with the FV Leiden. No difference was found among the patients with prothrombin mutation and their controls. DISCUSSION: Multi-variant analysis indicated that the difference in D-dimer between FV Leiden patients and controls was due to the greater number of patients with confirmed thrombosis in the former group, a finding supported by an independent prospective study on postoperative thrombosis. Neither D-dimer concentration nor thrombin generation depend on FV Leiden. The total amount of thrombin generated was not related to diagnosis. The prolonged thrombin generation noted in controls and FV Leiden heterozygotes with thrombosis may point out different thrombin generation profiles in different patient populations and requires further studies.

    Human aortic smooth muscle cells are insulin resistant at the receptor level but sensitive to IGF1 and IGF22009Inngår i: Journal of Molecular Endocrinology, ISSN 0952-5041, E-ISSN 1479-6813, Vol. 43, nr 5-6, s. 231-239Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Whether insulin, in physiological concentrations, has direct effects on vascular smooth muscle cells (VSMC) remains controversial. Our aim was to characterize the mechanism for insulin resistance in VSMCs. For comparison, effects of insulin-like growth factor (IGF)-I and IGF-II were also studied. Cultured human aortic smooth muscle cells (HASMC) were used. Receptor mRNA was analysed by quantitative RT-PCR and receptor protein by ELISA and Western Blot. The biological effects were studied by thymidine incorporation and glucose accumulation.

    In HASMC both mRNA and protein expression of IGF-I receptors (IGF-IR) were 5 fold higher compared to insulin receptor (IR). IR isoform A mRNA was 13 times more expressed than IR isoform B. Immunoprecipitation and Western blot showed co precipitation of IR and IGF-IR indicating the presence of hybrid IR/IGF-IR.

    Phosphorylation of the IGF-IR β-subunit was obtained by IGF-I 10-9-10-8mol l-1 and IGF-II 10-8mol l-1. IR β-subunit was phosphorylated by IGF-I 10-8mol l-1 but not by insulin. IGF-I stimulated IRS-I at 10-8mol l-1, Akt and Erk 1/2 at 10-9-10-8mol l-1, respectively. IGF-II stimulated Akt at 10-8mol l-1 whereas insulin had no effect. IGF-I and IGF-II at a concentration of 10-8-10-7mol l-1 significantly stimulated 3H-thymidine incorporation, whereas insulin did not. 14C-Glucose accumulation was stimulated by IGF-I or IGF-II 10-8-10-7mol l-1, and also by insulin 10-7mol l-1.

    Our results suggest that IGF-IR and hybrid IR/IGF-IR are activated by physiological concentrations of IGF-I and IGF-II in HASMC and this causes downstream signaling and biological effects, while insulin has no effect on its receptor or downstream signaling probably due to a preponderance of IGF-IR and incorporation of IR into hybrid IR/IGF-IR.

    Expression and function of IGF-I and insulin receptors in human micro- and macrovascular cells2008Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Insulin-like growth factor and insulin are phylogenetically closely related polypeptides and have large structural and biological similarities. Low circulating insulin-like growth factor-I (IGF-I), diabetes as well as insulin resistance have been implicated in the pathogenesis of cardiovascular disease, but the mechanisms involved are still not clear. Furthermore, little is known about direct effects of insulin-like growth factor-I (IGF-I) and insulin on human micro- and macrovascular cells.

    In these studies we investigated the expression and function of insulin-like growth factor-I receptors (IGF-IR) and insulin receptors (IR) in human micro- and macrovascular endothelial cells and in human coronary artery smooth muscle cells.

    Our results showed expression of both IGF-IR and IR in human dermal microvascular (HMVEC), aortic (HAEC) umbilical vein (HUVEC) and coronary artery (HCAEC) endothelial cells as well as in human coronary artery smooth muscle cells (HASMC). The gene expression of IGF-IR was several times more abundant than that of IR. Ligand binding studies confirmed that the IGF-IR was severalfold more abundant than the IR. It also demonstrated that insulin and glargine interacted with the IGF-IR with thousand- and hundredfold, respectively, less potency than IGF-I itself. The presence of IGF-IR and IR proteins and activation of their β-subunits was revealed by immunoprecipitation and Western blot analysis in human macrovascular endothelial cells and in coronary artery smooth muscle cells. At physiological concentrations (≤10-9 M) IGF-I and insulin activated their cognate receptors. The presence of hybrid IR/IGF-IR was shown through detection of the β-subunit for IGF-IR and IR on the same membrane by Western blot after immunoprecipitation with specific antibodies against either IGF-IR or IR, implying coprecipitation of the IGF-IR β-subunit and the IR β-subunit. The inability of physiological concentrations of insulin to phosphorylate IR β-subunit immunoprecipitated with IGF-IR antibodies and that IGF-I at physiological concentration activates the IR β-subunit is another evidence for the presence of the hybrid IR/IGF-IR. At physiological concentrations (≤10-9 M) IGF-I stimulated DNA synthesis and glucose incorporation into human coronary artery smooth muscle cells (HCASMC) and DNA synthesis in microvascular endothelial cells (HMVEC), but not in human macrovascular endothelial cells (HCAEC or HUVEC). No effect of insulin was found. Although physiological concentrations of insulin (≤10-9 M) were able to activate IR, insulin had no biological effects on the vascular cells studied. A possible explanation is that the insulin receptor signalling is too attenuated due to the presence of hybrid IR/IGF-IR and low number of IR expressed in the cells studied. Regarding the safety in the use of glargine, we show that glargine has 10-fold higher affinity for IGF-IR than human insulin. However, the glargine concentrations obtained in vivo during diabetes treatment is too low to affect the IGF-IR.

    In conclusions our studies provide experimental evidence that human micro- and macrovascular endothelial and vascular smooth muscle cells express both IGF-IR and IR. Our in vitro data suggest that the cells studied are sensitive to IGF-I, but insensitive to insulin and this is due to the preponderance of IGF-IR and presence of hybrid IR/IGF-IR.

    Abstract [en]

    Micro- and macroangiopathy are major causes of morbidity and mortality in patients with diabetes. Our aim was to characterize IGF-I receptor (IGF-IR) and insulin receptor (IR) in human micro- and macrovascular endothelial cells. Cultured human dermal microvascular endothelial cells (HMVEC) and human aortic endothelial cells (HAEC) were used. Gene expression was measured by quantitative real-time RT-PCR and receptor protein by ligand-binding assay. Phosphorylation of IGF-IR ß-subunit was analyzed by immunoprecipitation and Western blot. Glucose metabolism and DNA synthesis was assessed using [3H]glucose and [3H]thymidine incorporation, respectively. We detected gene expression of IGF-IR and IR in HAEC and HMVEC. IGF-IR gene expression was severalfold higher than that of IR. The specific binding of 125I-IGF-I was higher than that of 125I-insulin in HAEC and HMVEC. Insulin and the new, long-acting insulin analog glargine interacted with the IGF-IR with thousand- and hundred-fold less potency than IGF-I itself. Phosphorylation of the IGF-IR ß-subunit was shown in HAEC for IGF-I (10-8 M) and insulin (10-6 M) and in HMVEC for IGF-I and glargine (10-8 M, 10-6 M). IGF-I 10-7 M stimulated incorporation of [3H]thymidine into DNA, and 10-9–10-7 M also the incorporation of [3H]glucose in HMVEC, whereas glargine and insulin had no significant effects at 10-9–10-7 M. Human micro- and macrovascular endothelial cells express more IGF-IR than IR. IGF-I and high concentrations of glargine and insulin  ctivates the IGF-IR. Glargine has a higher affinity than insulin for the IGF-IR but probably has no effect on DNA synthesis at concentrations reached in vivo.

    Abstract [en]

    Vascular complications are common in diabetes. IGF-I receptors (IGF-IR) and insulin receptors (IR) in endothelial cells might respond to altered levels of IGF-I and insulin, resulting in altered endothelial function in diabetes. We therefore studied IGF-IR and IR gene expression, ligand binding, receptor protein, and phosphorylation in human umbilical vein endothelial cells (HUVEC). IGF-IR mRNA was more abundant than IRmRNAin freshly isolatedHUVEC(IGF-IR/IR ratio 7.1±1.5) and in culturedHUVEC(ratio 3.5±0.51). Accordingly, specific binding of 125I-IGF-I (0.64±0.25%) was higher than that of 125I-insulin (0.25±0.09%). Protein was detected for both  eceptors and IGF-I/insulin hybrid receptors. IGF-IR phosphorylation was stimulated by 10−10 to 10−8M IGF-I. IR were activated by 10−9 to 10−8M insulin and IGF-I. We conclude that HUVEC express more IGF-IR than IR, and also express hybrid receptors. Both IGF-I and insulin phosphorylate their own receptors but only IGF-I seems to phosphorylate hybrid receptors.

    Abstract [en]

    Objective: Coronary artery disease is a prevalent cause of morbidity and mortality in diabetes. Little is known about insulin-like growth factor-I receptors (IGF-IR) and insulin receptors (IR) in human coronary endothelium. Our aim was to characterize IGF-IR and IR in human coronary artery endothelial cells (HCAEC).

    Design: Cultured human coronary artery endothelial cells were used. Gene expression was measured by quantitative real-time RTPCR analysis and receptor affinity by ligand binding. Receptor protein, phosphorylation of IGF-IR and IR b-subunit as well as the presence of hybrid insulin receptor/Insulin-like growth factor-I receptor (Hybrid IR/IGF-IR) was analyzed by immunoprecipitation and Western blot. Postreceptor effects of insulin and IGF-I were assed by 3H-thymidine incorporation.

    Results: The gene expression of IGF-IR was several folds higher than that of IR. and insulin receptor isoform A (IR-A) was 20-fold more expressed than insulin receptor isoform B (IR-B) in HCAEC. The specific binding of 125I-IGF-I was higher than that of 125Iinsulin. Insulin and the new long acting insulin analog, glargine, interacted with the IGF-IR with over thousand and 100-fold less potency than IGF-I itself, whereas IGF-II had 6 times lower potency than IGF-I. Phosphorylation of the IGF-IR b-subunit was obtained by concentrations of 10-10–10-8 M IGF-I, 10-6 M of insulin, inconsistently by 10-8 M insulin and not at all by 10-10–10-9 M insulin. The IR b-subunit was phosphorylated by insulin and IGF-I at concentrations of 10-9–10-8 M. When immunoprecipitating with specific monoclonal anti-IR or anti-IGF-IR a-subunit antibodies we found bands situated in slightly different positions suggesting the presence of Hybrid IR/IGF-IR. IGF-I, IGF-II and insulin (10-9–10-7 M) had no significant effect on 3H-thymidine incorporation into DNA.

    Conclusions: Human coronary endothelial cells express more IGF-IR than IR, mainly IR-A, and also Hybrid IR/IGF-IR. Both IGF-I and insulin phosphorylate their receptors, but only IGF-I seems to phosphorylate Hybrid IR/IGF-IR. Our study provides experimental evidence for a possible role of IGF-IR, IR and Hybrid IR/IGF-IR in human coronary artery endothelial cells.

    Abstract [en]

    Aims/hypothesis: Hyperinsulinaemia and insulin resistance, as well as low IGF-I, have been implicated in the pathogenesis of cardiovascular disease. Little is known about direct effects of IGF-I and insulin on human coronary artery smooth muscle cells (HCASMCs). Our aim was to characterise the expression and function of IGF-I receptor (IGF-IR) and insulin receptor (IR) in HCASMCs. Materials and methods: Cultured HCASMCs were used. mRNA expression was measured by quantitative real-time RT-PCR analysis. Receptor proteins, phosphorylation of β-subunits and the presence of hybrid IR/IGF-IR were analysed by immunoprecipitation and western blotting. DNA synthesis and glucose metabolism were assessed using [3H]thymidine incorporation and D-[U-14C]glucose accumulation respectively. Results: The mRNA expression of IGF-IR was approximately eight-fold higher than that of IR in HCASMCs. The presence of IGF-IR and IR could be demonstrated by immunoprecipitation and western blot analysis. Phosphorylation of the IGF-IR β-subunit was obtained by IGF-I at 10−10–10−8 mol/l and insulin at 10−8 mol/l. Insulin and IGF-I at 10−10–10−9 mol/l phosphorylated the IR β-subunit. When immunoprecipitated with monoclonal anti-IR α-subunit or IGF-IR α-subunit antibodies, we found bands in slightly different positions, suggesting the presence of hybrid IR/IGF-IR. IGF-I at 10−9–10−8 mol/l significantly stimulated [3H]thymidine incorporation and at a concentration of 10−9–10−7 mol/l also D-[U-14C]glucose accumulation in HCASMCs. Insulin at 10−9–10−7 mol/l had no effect on DNA synthesis, but increased glucose accumulation at 10−7 mol/l. Conclusions/interpretation: Our study provides experimental evidence that IGF-IR and possibly hybrid IR/IGF-IR play a role in HCASMCs.

    Differential lipid profile and hormonal response in type 2 diabetes by exogenous insulin aspart versus the insulin secretagogue repaglinide, at the same glycemic control2009Inngår i: Acta Diabetologica, ISSN 0940-5429, E-ISSN 1432-5233, Vol. 46, nr 1, s. 35-42Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Our aim was to study, at the same glycemic control, how treatment with either the insulin secretagogue repaglinide or exogenous insulin aspart affects endogenous insulin secretion, plasma insulin and IAPP (islet amyloid polypeptide) levels, GH-IGF (growth hormone-insulin-like growth factor) axis and plasma lipoprotein concentrations in patients with type 2 diabetes. Five patients, age 65.0 +/- A 4.1 years (mean +/- A SE), body weight 82.5 +/- A 5.0 kg, BMI (body mass index) 27.7 +/- A 1.5 kg/m(2) were treated for 10 weeks with repaglinide or insulin aspart in a randomized, cross-over study. At the end of each treatment a 24-h metabolic profile was performed. Blood glucose, C-peptide, free human insulin, free total (human and analogue) insulin, proinsulin, IAPP, IGF-I, IGFBP-1 (IGF binding protein-1), GHBP (growth hormone binding protein) and plasma lipoprotein concentrations were measured. Similar 24-h blood glucose profiles were obtained with repaglinide and insulin aspart treatment. During the repaglinide treatment, the meal related peaks of C-peptide and free human insulin were about twofold higher than during treatment with insulin aspart. Proinsulin, GHBP were higher and IAPP levels tended to be higher during repaglinide compared to insulin aspart. Postprandial plasma total cholesterol, triglycerides and apolipoprotein B concentrations were higher on repaglinide than on insulin aspart treatment. Our results show that, at the same glycemic control, treatment with exogenous insulin aspart in comparison with the insulin secretagogue repaglinide result in a lower endogenous insulin secretion, and a tendency towards a less atherogenic postprandial lipid profile.

    Morphological examination of the termination pattern of substance P-immunoreactive nerve fibers in human antral mucosa2002Inngår i: Regulatory Peptides, ISSN 0167-0115, E-ISSN 1873-1686, Vol. 107, nr 1-3, s. 79-86Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The termination pattern of substance P (SP)-containing axons in human antral mucosa was examined using immunohistochemical techniques at the light and electron microscopic level. SP-immunoreactive (IR) axons were found to extend towards the pit region of the glands, where intraepithelial axons were observed. Electron microscopy showed immunostained axon profiles in close contact with the basement membrane of surface mucous cells. Membrane-to-membrane contacts between labeled axons and myofibroblast-like cells were identified, and SP-IR axons that were apposed to the epithelium were also in contact with subjacent myofibroblast-like cells. The anatomical relationship between SP-IR axons and the cells of the muscularis mucosae was investigated by light microscopy. Immunoreactivity for a-smooth muscle actin (a-sma) was used to visualize the smooth muscle cells, and the a-sma-IR cells were found to create a network that surrounded the gastric glands. Immunostained varicose axons ran alongside and in close apposition to the labeled muscle strands. Ultrastructural examination showed close contacts between SP-IR axon profiles and smooth muscle-like cells. In conclusion, SP-containing neurons may be important for sensory and secretomotor functions in the human antral mucosa.

    Health-illness transition among persons using advanced medical technology at home2011Inngår i: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 25, nr 2, s. 253-261Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Scand J Caring Sci; 2010 Health-illness transition among persons using advanced medical technology at home. This study aimed to elucidate meanings of health-illness transition experiences among adult persons using advanced medical technology at home. As an increasing number of persons perform self-care while using different sorts of advanced medical technology at home, knowledge about health-illness transition experiences in this situation may be useful to caregivers in supporting these patients. A qualitative design was used. Five women and five men, all of whom performed self-care at home, either using long-term oxygen therapy from a ventilator or oxygen cylinder, or performing peritoneal or haemodialysis, were interviewed. Ethics committee approval was obtained. Informed consent was received from all participants, and ethical issues concerning their rights in research were raised. The interviews were analysed using a phenomenological hermeneutical methodology, including both an inductive and a deductive structural analysis. This method offers possibilities to obtain an increased understanding by uncovering a deeper meaning of lived experiences through interviews transcribed as texts. The health-illness transition for adult persons in this context was found to mean a learning process of accepting, managing, adjusting and improving daily life with technology, facilitated by realizing the gain from technology at home. Further, the meaning of the health-illness transition experience was interpreted as contentment with being part of the active and conscious process towards transcending into a new state of living, in which the individual and the technology were in tune. The healthy transition experience was characterized by human growth and becoming. This study elucidates one meaning of health-illness transition experiences in relation to the use of advanced medical technology on a more generic level, independent of the specific type of technology used. A positive attitude towards technology at home facilitates the transition.

    Living with an adult family member using advanced medical technology at home2011Inngår i: Nursing Inquiry, ISSN 1320-7881, E-ISSN 1440-1800, Vol. 18, nr 4, s. 336-347Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    An increased number of chronically ill adults perform self-care while using different sorts of advanced medical technology at home. This hermeneutical study aimed to gain a deeper understanding of the meaning of living with an adult family member using advanced medical technology at home. Eleven next of kin to adults performing self-care at home, either using long-term oxygen from a cylinder or ventilator, or performing peritoneal or haemodialysis, were interviewed. The qualitative interviews were analysed using a Gadamerian methodology. The main interpretation explained the meaning as rhythmical patterns of connectedness versus separation, and of sorrow versus reconciliation. Dependence on others was shown in the need for support from health-care professionals and significant others. In conclusion, next of kin took considerable responsibility for dependent-care. All next of kin were positive to the idea of bringing the technology home, even though their own needs were receded into the background, while focusing on the best for the patient. The results were discussed in relation to dependent-care and transition, which may have an influence on the self-care of next of kin and patients. The study revealed a need for further nursing attention to next of kin in this context.

    Self-Care Agency and Perceived Health Among Persons Using Advanced Medical Technology at Home2012Inngår i: Journal of Advanced Nursing, ISSN 0309-2402, E-ISSN 1365-2648, Vol. 68, nr 4, s. 806-815Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aim. This paper is a report of a study of self-care agency and perceived health in a group ofpersons using advanced medical technology at home.

    Background. An increasing number of persons are using medical technology for self-care. Few studies describe daily life in this context at an overriding level, irrespective of the specific sort of technology. A connection between self-care, perceived health and sense of coherence has previous been implied.

    Methods. A descriptive, comparative, cross-sectional quantitative design was used. Data were collected from a questionnaire in the winter 2009/2010. The questionnaire addressed perceiveed health and daily life with medical technology, and applied Swedish versions of the Appraisal of Self-care Agency scale and the 13-item version of Antonovsky’s sense of coherence scale.

    Results. The questionnaire was answered by 180 adults performing self-care at home involving long-term oxygen, a ventilator, peritoneal or blood dialysis. Health-related and technology-related variables in daily life were rated as satisfactory to a high extent. Perceived health was rated significantly lower among participants using long-term oxygen. Sufficient sense of coherence and knowledge of how to use technology, close contacts with other persons, and not feeling helpless contributed positively as factors for self-care agency. Positive factors for perceived health were being satisfied with life, having an active life, and not feeling helpless, while age was a negative factor.

    Conclusion. Daily life is manageable for persons using these types of technology. Long-term oxygen treatment and advanced age can be seen as risk factors for perceiving ill health.

    Sensitivity to heat in MS patients: a factor strongly influencing symptomology - an explorative survey2011Inngår i: BMC NEUROLOGY, ISSN 1471-2377, Vol. 11, nr 27Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Many individuals diagnosed with Multiple Sclerosis (MS) are sensitive to increased body temperature, which has been recognized as correlating with the symptom of fatigue. The need to explore this association has been highlighted. The aim of this study was to investigate the occurrence of heat sensitivity and its relations to disease course, disability, common MS-related symptoms and ongoing immunosuppressive treatments among individuals 65 years of age or younger diagnosed with MS. Methods: A cross-sectional designed survey was undertaken. A questionnaire was sent to MS-patients with an Expanded Disability Status Score (EDSS) in the interval of 0-6.5 and who were between 20 and 65 years of age, living in an eastern region of Sweden (n = 334). Besides occurrence of heat sensitivity (Yes/No) and corresponding questions, the Fatigue Severity Scale (FSS), the MS-related symptom checklist and the Perceived Deficit Questionnaire (PDQ) were included. Data were analysed in relation to data level using Chi-square, Mann Whitney U-test, and Students t-test. Pearsons and Spearmans correlations were calculated. In the logistic regression analyses (enter) dichotomized MS-symptoms were used as dependent variables, and EDSS, disease-course, time since onset, heat-sensitivity, age and sex (female/male) were independent variables. In the linear regression analyses, enter, mean FSS and summarized PDQ were entered as dependent variables and EDSS, disease-course, time since onset, heat sensitivity, age and sex (female/male) were independent variables. Results: Of the responding patients (n = 256), 58% reported heat sensitivity. The regression analyses revealed heat sensitivity as a significant factor relating not only to fatigue (p andlt; 0.001), but also to several other common MS symptoms such as pain (p andlt; 0.001), concentration difficulties (p andlt; 0.001), and urination urgency (p = 0.009). Conclusions: Heat sensitivity in MS patients is a key symptom that is highly correlated with disabling symptoms such as fatigue, pain, concentration difficulty and urination urgency.

    Nurses' reasoning process during care planning taking pressure ulcer prevention as an example. A think-aloud study2007Inngår i: International Journal of Nursing Studies, ISSN 0020-7489, E-ISSN 1873-491X, Vol. 44, nr 7, s. 1109-1119Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Nurses' clinical reasoning is of great importance for the delivery of safe and efficient care. Pressure ulcer prevention allows a variety of aspects within nursing to be viewed. Objective: The aim of this study was to describe both the process and the content of nurses' reasoning during care planning at different nursing homes, using pressure ulcer prevention as an example. Design: A qualitative research design was chosen. Settings: Seven different nursing homes within one community were included. Participants: Eleven registered nurses were interviewed. Method: The methods used were think-aloud technique, protocol analysis and qualitative content analysis. Client simulation illustrating transition was used. The case used for care planning was in three parts covering the transition from hospital until 3 weeks in the nursing home. Result: Most nurses in this study conducted direct and indirect reasoning in a wide range of areas in connection with pressure ulcer prevention. The reasoning focused different parts of the nursing process depending on part of the case. Complex assertations as well as strategies aiming to reduce cognitive strain were rare. Nurses involved in direct nursing care held a broader reasoning than consultant nurses. Both explanations and actions based on older ideas and traditions occurred. Conclusions: Reasoning concerning pressure ulcer prevention while care planning was dominated by routine thinking. Knowing the person over a period of time made a more complex reasoning possible. The nurses' experience, knowledge together with how close to the elderly the nurses work seem to be important factors that affect the content of reasoning. © 2006 Elsevier Ltd. All rights reserved.

    Assessing patient's care requirements: A comparison of instruments2007Inngår i: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 21, nr 3, s. 390-396Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The purpose of this study was to compare two patient classification instruments developed in different countries, Perroca's (Brazil) and the Beakta (Sweden) systems and to investigate if both instruments equally assess patients' care requirements. The survey sample comprised 85 patients from a university hospital in southeast Sweden. Statistical analysis used Spearman's correlation and Kappa. The Spearman's correlation coefficient for total scores and classifications were 0.83 and 0.80, respectively (P-value < 0.01). The level of agreement between the instruments related to the different care categories pointed to an overall kw of 0.60 (95% CI: 0.50-0.71). The findings indicate a high degree of association between the total scores and patient classification assessment using the Beakta and Perroca systems and also a moderate level of agreement between the two instruments in the different care categories. There are few surveys that compare classification instruments between countries making it difficult to know to what extent cultural differences influence measurement approaches. © 2007 Nordic College of Caring Science.

    Utilization of patient classification systems in Swedish hospitals and the degree of satisfaction among nursing staff2007Inngår i: Journal of Nursing Management, ISSN 0966-0429, E-ISSN 1365-2834, Vol. 15, nr 5, s. 472-480Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background Although patient classification tools have been used in Sweden since the 1980s, few studies have examined how they are utilized and monitored. Aim This paper investigates the patient classification systems implemented in hospitals in the country as well as the level of satisfaction of nurses with the implemented instrument. Method A postal survey method was used in which a total of 128 questionnaires were sent to nurse managers. Twenty-three hospitals were identified with patient classification systems currently in operation. Results and conclusion The Zebra and Beakta systems are the most commonly used instruments. Nurse managers appear to be satisfied with the patient classification systems in use on their wards as a whole except for their inability to measure the quality of care provided, the time spent to use the instruments and the fact that the administration do not estimate nursing staff requirements using the system.

    Attitudes of swedish general practitioners and nurses to working with lifestyle change, with special reference to alcohol consumption2005Inngår i: Alcohol and Alcoholism, ISSN 0735-0414, E-ISSN 1464-3502, Vol. 40, nr 5, s. 388-393Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aims: To explore the attitudes of Swedish general practitioners (GPs) a nd nurses to secondary alcohol prevention (early identification of, and intervention for, alcohol-related problems) and compare it to their attitudes to other important lifestyle behaviours such as smoking, stress, exercise, and overweight. Methods: An adjusted version of The WHO Collaborative Study Questionnaire for General Practitioners was posted to all GPs and nurses in the County of Skaraborg, Sweden, 68 GPs and 193 nurses responded. Results: The importance of drinking alcohol moderately, counselling skills on reducing alcohol consumption and perceived current effectiveness in helping patients change lifestyle behaviours ranked lower than working with all the other lifestyle behaviours. The nurses rated their potential effectiveness in helping patients change lifestyle higher than that of GPs for all the lifestyle behaviours. Nurses receiving more alcohol-related education had more positive attitudes than nurses with less education. For alcohol, the GPs assessed their role adequacy, role legitimacy and motivation higher than that of the nurses. The main obstacles for the GPs to carry out alcohol intervention were lack of training in counselling for reducing alcohol consumption, time constraints, and the fact that the doctors did not know how to identify problem drinkers who have no obvious symptoms of excess consumption. Conclusion: GPs and the nurses estimated their alcohol-related competence as lower than working with many other health-related lifestyles. These results can be explained by lack of practical skills, lack of training in suitable intervention techniques, and unsupportive working environments. All these elements must be considered when planning secondary alcohol prevention programs in primary health care. © The Author 2005.

    A technique based on laser Doppler flowmetry and photoplethysmography for simultaneously monitoring blood flow at different tissue depths2010Inngår i: Medical and Biological Engineering and Computing, ISSN 0140-0118, Vol. 48, nr 5, s. 415-422Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this study was to validate a non-invasive optical probe for simultaneous blood flow measurement at different vascular depths combining three photoplethysmography (PPG) channels and laser Doppler flowmeter (LDF). Wavelengths of the PPG were near-infrared 810 nm with source-to-detector separation of 10 and 25 mm, and green 560 nm with source-to-detector separation of 4 mm. The probe is intended for clinical studies of pressure ulcer aetiology. The probe was placed over the trapezius muscle, and depths from the skin to the trapezius muscle were measured using ultrasound and varied between 3.8 and 23 mm in the 11 subjects included. A provocation procedure inducing a local enhancement of blood flow in the trapezius muscle was used. Blood flows at rest and post-exercise were compared. It can be concluded that this probe is useful as a tool for discriminating between blood flows at different vascular tissue depths. The vascular depths reached for the different channels in this study were at least 23 mm for the near-infrared PPG channel (source-to-detector separation 25 mm), 10-15 mm for the near-infrared PPG channel (separation 10 mm), and shallower than 4 mm for both the green PPG channel (separation 4 mm) and LDF.

    Health-related quality of life after vertebral or hip fracture: a seven-year follow-up study2009Inngår i: BMC Musculoskeletal Disorders, ISSN 1471-2474, E-ISSN 1471-2474, Vol. 10, nr 135Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background

    The negative impact of vertebral and hip low-energy fractures on health-related quality-of-life (HRQOL) has been demonstrated previously, but few prospective long-term follow-up studies have been conducted. This study aims to (i) investigate the changes and long-term impact of vertebral or hip fracture and between fracture groups on HRQOL in postmenopausal women prospectively between two and seven years after the inclusion fracture, (ii) compare HRQOL results between fracture and reference groups and (iii) study the relationship between HRQOL and physical performance, spinal deformity index and bone mineral density at seven-year follow-up.

    Methods

    Ninety-one women examined two years after a low-energy vertebral or hip fracture were invited to a new examination seven years after the diagnosis. HRQOL was examined using the SF-36 questionnaire and was compared with an age and sex-matched reference group. Physical function was assessed using tests and questionnaires. Bone mineral density was measured. Radiographs of the spine were evaluated using the visual semiquantitative technique. A longitudinal and cross-sectional design was used in this study. Statistical analyses included descriptive statistics, Student’s t-tests, ANCOVA, and partial correlation.

    Results

    Sixty-seven women participated. In the 42 women (mean age 75.8, SD 4.7) with vertebral fracture as inclusion fracture, bodily pain had deteriorated between two and seven years and might be explained by new fracture. Remaining pronounced reduction of HRQOL was seen in all domains except general health and mental health at seven-year follow-up in women with vertebral fractures compared to the reference group (p<0.05). All 25 women (mean age 75.0, SD 4.7) with hip fracture as inclusion fracture had no significant changes in HRQOL between two and seven years and did not differ from the reference group regarding HRQOL after seven years. The vertebral group had significantly lower values for bodily pain, vitality, role-emotional function and mental health compared to the hip group. HRQOL showed a positive relationship between physical activity, static balance and handgrip strength.

    Conclusions

    The long-term reduction of HRQOL in women with vertebral fracture emerged clearly in this study. The relationships between HRQOL and physical performance in women with vertebral and hip fracture raise questions for more research.

    A striving for independence: a qualitative study of women living with vertebral fractureManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Background: Quantitative studies using generic and disease-specific health-related quality of life (HRQOL) questionnaires have shown that osteoporosis-related vertebral fractures have a significant negative effect on HRQOL, but there are only few studies that address what it means to live with vertebral fracture from a deeper experiential perspective. How HRQOL and daily life are affected several years after vertebral fracture and how women cope with this are more unclear. This study aimed to describe how HRQOL and daily life had been affected in women with vertebral fracture several years after diagnosis.

    Methods: The study design was qualitative. Semi-structured interviews were conducted with ten Swedish women during 2008. Data were analysed using qualitative inductive content analysis.

    Results: The findings of this study revealed three themes related to the influence on HRQOL and daily life: A threatened independence, i.e. back pain, anxiety, negative impact on self-image and consequences in daily life; Strategies for maintaining independence, i.e. coping, self-care and support; and The importance of maintaining independence, i.e. the ability to perform everyday activities, social interaction and having something meaningful to do. As a result of how their HRQOL and daily life have been affected by their vertebral fractures, the women in this study are striving for independence or maintaining their independence by trying to manage the different types of symptoms and consequences in different ways.

    Conclusion: HRQOL and daily life were strongly affected in a negative way by the impact of the vertebral fracture. One possible effective intervention for the future may be to support women in using self-management strategies so that they can be in charge of their situation and positively influence their HRQOL and daily life to achieve independence, but further evaluation is still needed. Information from this study may provide a foundation for guidelines for health care professionals to offer empathic and supportive care to women living with prevalent vertebral fracture.

    Characterisation and utility of thiopurine methyltransferase and thiopurine metabolite measurements in autoimmune hepatitis2010Inngår i: Journal of Hepatology, ISSN 0168-8278, E-ISSN 1600-0641, Vol. 52, nr 1, s. 106-111Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background and Aims: Corticosteroids alone or in conjunction with azathioprine (AZA) is the standard treatment in autoimmune hepatitis (AiH). Individual variations in thiopurine (TP) metabolism may affect both drug efficacy and toxicity. Our aim was to investigate the utility of thiopurine methyl transferase (TPMT) as well as thioguanine nucleotide (TGN) and methylthioinosine monophosphate (meTIMP) metabolite measurements with regard to clinical outcome. Methods: Two hundred thirty-eight patients with AM were included in this cross-sectional study. TPMT status was assessed in all patients, while TGN and meTIMP were measured in patients with ongoing TP medication. Clinical outcome was evaluated by liver tests and the ability to withdraw steroids. Results: TPMT genotyping (n = 229) revealed 207 (90.4%) wildtype and 22 heterozygous patients. One hundred forty-three patients had ongoing TP therapy with AZA (n = 134) or mercaptopurine (MP; n = 9): response was judged as complete response (CR) in 113 patients and partial response (PR) in 30 patients. Both TP dose (1.64 vs 1.19 mg/kg; p = 0.012) and TPMT activity (14.3 vs 13.5; p = 0.05) were higher in PR, resulting in similar TGN levels (PR: 121 pmol/8 x 10(8) red blood cells [RBC]; CR: 113 pmol/8 x 10(8) RBC; p = 0.33) but higher meTIMP levels in PR (1350 vs 400 pmol/8 x 10(8) RBC; p = 0.004). Patients able to withdraw steroids or who were using less than= 5 mg prednisolone daily were treated with lower TP doses than patients on higher steroid doses (1.15 vs 1.18 vs 1.82 mg/kg; p less than 0.001). Conclusions: TP metabolite measurements are of clinical value in AM patients who do not respond to standard TP treatment and for the identification of a shifted metabolism, which may demand an alternative treatment strategy.

    Disease knowledge and adherence to treatment in patients with familial hypercholesterolemia2006Inngår i: Journal of Cardiovascular Nursing, ISSN 0889-4655, E-ISSN 1550-5049, Vol. 21, nr 2, s. 103-108Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Familial hypercholesterolemia (FH) is one of the most common genetic metabolic disorders and is associated with a high risk of premature coronary heart disease. Primary prevention directed at lifestyle changes, combined with preventive medical treatment, is the most important way to reduce the risk of coronary heart disease in individuals with FH. Knowledge about the condition and adherence to drug treatment may facilitate reaching treatment goals. OBJECTIVE: The purpose of this study was to describe disease knowledge and adherence to treatment in patients with FH. SUBJECTS AND METHODS: Seventy-four patients, more than 18 years of age, with FH were asked to participate. A questionnaire on disease knowledge about FH and adherence to drug treatment was sent to the patients. Response rate was 92% (n = 68). Drug treatment, laboratory results, blood pressure, and smoking were also documented. RESULTS: Most patients knew about cholesterol, prevention, and the reason for drug treatment but were less informed about the risk of genetic transmission and family history. No significant correlation was found between knowledge and low-density lipoprotein cholesterol level. A significant, negative correlation between adherence and low-density lipoprotein cholesterol level was found (r = -.354, P < .01). CONCLUSIONS: Patients with FH had scant understanding about the risk of genetic transmission and family history. High adherence to drug prescription has significant correlation to low-density lipoprotein cholesterol level. © 2006 Lippincott Williams & Wilkins, Inc.

    Normal D-dimer concentration is a common finding in symptomatic outpatients with distal deep vein thrombosis2005Inngår i: Blood Coagulation and Fibrinolysis, ISSN 0957-5235, E-ISSN 1473-5733, Vol. 16, nr 7, s. 517-523Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The D-dimer analysis has been shown to have a high sensitivity and a high negative predictive value for the exclusion of deep vein thrombosis (DVT). However, most D-dimer studies, including recent clinical management studies, are performed without examination of the calf veins and/or performed on patient populations with a predominance of proximal DVT. The purpose of this study was to evaluate the diagnostic performance of the D-dimer test in a population with a suspected high incidence of distal DVT. In the present study, 393 outpatients with clinically suspected symptomatic DVT of the lower extremities were examined with whole-leg duplex ultrasonography. The D-dimer analysis was performed using an automated micro-latex assay (Tina-quant). A total of 137 of 393 patients had a proven DVT, with the majority presenting with distal DVT (59%). Twenty-eight out of 81 patients with distal DVT had a normal D-dimer, compared with two of 56 patients with proximal DVT. The sensitivity for distal DVT was only 65% compared with 96% for proximal DVT, the negative predictive values were 84 and 99%, respectively. In conclusion, the prevalence of distal DVT in a study population seems to have a great impact on the diagnostic performance of the D-dimer analysis. The study results also show that normal D-dimer levels do not exclude distal DVT in outpatients, instead, it can be hypothesized that normal D-dimer levels exclude DVT that require treatment, as indicated by the good outcome in recent management studies. © 2005 Lippincott Williams & Wilkins.

    Human microvascular endothelial cells are sensitive to IGF-I but resistant to insulin at the receptor level2008Inngår i: Molecular and Cellular Endocrinology, ISSN 0303-7207, E-ISSN 1872-8057, Vol. 296, nr 1-2, s. 58-63Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Human microvascular endothelial cells (HMVEC) are sensitive to IGF-I but insulin resistant and express several times more IGF-I receptors (IGF-IR) than insulin receptors (IR). Our aim was to investigate the mechanism of this insulin resistance in cultured HMVEC by studying receptor activation and signal propagation downstream.

    propagation downstream. The IGF-IR β-subunit and the IR β-subunitwere detected and found to co-precipitate. IRAwas themajor IR isoformexpressed in HMVEC. IGF-I 10−9 to 10−8M phosphorylated its cognate receptor β-subunit. IGF- I also phosphorylated the IR β-subunit at 10−9 M. Phosphorylation of insulin receptor substrate 1 was obtained by IGF-I 10−9 to 10−8 M. Akt was phosphorylated by IGF-I at 10−8 to 10−7M and by insulin 10−7M. IGF-I at 10−8 to 10−6M significantly increased DNA-synthesis. We conclude that microvascular endothelial cells are sensitive to IGF-I but resistant to insulin due to a preponderance of IGF-I receptors and sequestration of insulin receptors into insulin/IGF-I hybrid receptors.

    Malnutrition in a home-living older population: prevalence, incidence and risk factors. A prospective study2009Inngår i: JOURNAL OF CLINICAL NURSING, ISSN 0962-1067, Vol. 18, nr 9, s. 1354-1364Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To prospectively investigate and describe the prevalence and incidence of malnutrition among home-living older people, related to demographic and medical factors, self-perceived health and health-related quality of life. Another aim was to find predictors for developing risk of malnutrition.

    Risk factors for malnutrition have previously been identified as diseases, several medications, low functional status, symptoms of depression and inadequate nutrient intake. Most studies are cross-sectionally performed at hospitals or in nursing care settings.

    A prospective study with a sample of 579 home-living older people, randomly selected from a local national register. Examinations were performed at baseline and yearly follow-ups two to four times.

    Questionnaires validated and tested for reliability, to detect risk of malnutrition (Mini Nutritional Assessment), symptoms of depression (Geriatric Depression Scale-20), cognitive function (Mini Mental State Examination), health-related quality of life (Nottingham Health Profile), well-being (Philadelphia Geriatric Center Multilevel Assessment Instrument) self-perceived health, demographic factors, anthropometry and biochemical examinations. Predictors were searched for through multiple logistic regression analysis with the MNA as dependent factor.

    The prevalence of risk for malnutrition was 14.5%, according to the MNA. Two risk factors for malnutrition were lower handgrip strength and lower self-perceived health. The incidence of risk for malnutrition at follow-ups was between 7.6% and 16.2%. Predictors for developing malnutrition were higher age, lower self-perceived health and more symptoms of depression. Men with symptoms of depression had a higher risk of developing malnutrition.

    Lower self-perceived health had the highest power to predict risk for malnutrition, with increased number of depression symptoms and higher age as second and third predictors.

    A regular and combined assessment using the Mini Nutrition Assessment, Geriatric Depression Scale-20 and self-perceived health as a base for identifying people in need, is one way to prevent the development of malnutrition.

    Self-perceived health among older women living in their own residence2007Inngår i: International Journal of Older People Nursing, ISSN 1748-3735, E-ISSN 1748-3743, Vol. 2, nr 2, s. 111-118Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aim. The aim was to characterize women who perceived themselves as healthy and to compare them with women who perceived themselves as less healthy with regard to demographical, social, medical and functional factors. Another aim was to describe changes within the healthy group after one year.

    Background. Self-perceived health is influenced by several factors, of which diseases and illness are only a part.

    Method and participants. Two hundred and seventy-eight women, 75 and 80 years old, of which 50% (n ¼ 139) perceived themselves as healthy and less healthy, respectively. Data were collected by using the Nottingham Health Profile, Geriatric Depression Scale, Mini Nutritional Assessment, Mini Mental State Examination and Philadelphia Geriatric Center Multilevel Assessment Instrument, in two examinations at intervals of one year.

    Results. The women in the healthy group were characterized as having no or low depression symptoms (P ¼ 0.016), better physical mobility (P ¼ 0.029) and better physical health (P < 0.001). Furthermore no or less pain, fewer doctor visits, more energy and fewer negative emotional reactions were predictors for self-perceived health in the healthy group at the one-year follow-up.

    Conclusion. The most important predictors associated with perceiving oneself as healthy were no or few depression symptoms, physical mobility and good physical health.

    Relevance to clinical practice. Attention has to be paid to women’s mood, physical health, mobility, pain and energy to help them stay healthy.

    Expression of vanilloid receptor-1 in epithelial cells of human antral gastric mucosa2005Inngår i: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 40, nr 7, s. 775-782Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective. Capsaicin, which acts by binding to the vanilloid receptor-1 (VR1), has been shown to give protection against gastric mucosal injury and to enhance healing of gastric ulcers. Although VR1 has recently been reported to be present in non-neural tissues, it is primarily considered to be expressed in nociceptor sensory neurons of small diameter. The aim of the present study was to evaluate the distribution of VR1 immunoreactivity in the normal human gastric mucosa. Material and methods. Ten volunteers underwent gastroscopy and biopsies were obtained from the corpus and the antrum. The specimens were labelled immunohistochemically using polyclonal goat anti-VR1 and evaluated at the light- and electronmicroscopic level. Moreover, post-embedding immunogold labelling was performed and subsequently analysed at the electronmicroscopic level. Results. In the antrum, VR1 immunoreactivity was located in epithelial cells that fulfilled the criteria of endocrine cells of the "open type". These cells were located primarily in the neck region of the antral glands and the labelling was concentrated on the microvilli of these cells. At the ultrastructural level, round granulae with differences in electron density were identified in the basal compartment of the labelled cells. VR1 immunoreactivity was also identified in axon-like structures that were located in the lamina propria, often in close vicinity of vessels, in the corpus as well as in the antrum. Conclusions. VR1-immunoreactivity was evident in antral epithelial cells exhibiting characteristics of endocrine-like cells. This may indicate that the gastroprotective effects of capsaicin, which hitherto have been attributed to primary afferent neurons, at least partly may be explained by an action on specific epithelial cells in the antrum. © 2005 Taylor & Francis.

    Reliability of breath-alcohol analysis in individuals with gastroesophageal reflux disease1999Inngår i: Journal of Forensic Sciences, ISSN 0022-1198, E-ISSN 1556-4029, Vol. 44, nr 4, s. 814-818Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Gastroesophageal reflux disease (GERD) is widespread in the population among all age groups and in both sexes. The reliability of breath alcohol analysis in subjects suffering from GERD is unknown. We investigated the relationship between breath-alcohol concentration (BrAC) and blood-alcohol concentration (BAC) in 5 male and 5 female subjects all suffering from severe gastroesophageal reflux disease and scheduled for antireflux surgery. Each subject served in two experiments in random order about 1-2 weeks apart. Both times they drank the same dose of ethanol (~0.3 g/kg) as either beer, white wine, or vodka mixed with orange juice before venous blood and end-expired breath samples were obtained at 5-10 min intervals for 4 h. Ah attempt was made to provoke gastroesophageal reflux in one of the drinking experiments by applying an abdominal compression belt, Blood-ethanol concentration was determined by headspace gas chromatography and breath-ethanol was measured with an electrochemical instrument (Alcolmeter SD-400) of a quantitative infrared analyzer (Data-Master). During the absorption of alcohol, which occurred during the first 90 min after the start of drinking, BrAC (mg/210 L) tended to be the same of higher than venous BAC (mg/dL). In the post-peak phase, the BAC al ways exceeded BrAC. Four of the 10 subjects definitely experienced gastric reflux during the study although this did not result in widely deviant BrAC readings compared with BAC when sampling occurred at 5- min intervals. We conclude that the risk of alcohol erupting from the stomach into the mouth owing to gastric reflux and falsely increasing the result of an evidential breath-alcohol test is highly improbable.
