    • Objective To determine patient perceptions of generic medicines 2 and 6 months after percutaneous coronary intervention (PCI), and to determine whether these perceptions moderate medication adherence. Design Prospective multicentre cohort study with repeated measures of perceptions of generic medicines and medication adherence. Setting The CONCARD(PCI) study conducted at seven large referral PCI centres in Norway and Denmark between June 2017 and May 2020. Participants A total of 3417 adults (78% men), using both generic and brand name medicines, with a mean age of 66 years (SD 11) who underwent PCI were followed up 2 and 6 months after discharge from hospital. Main outcome measures Perceptions of generic medicines were the main outcome. The secondary outcome was medication adherence. Results Perceptions of generic medicines were significantly more negative at 2 than at 6 months (1.10, 95% CI 0.41 to 1.79, p=0.002). Female sex (-4.21, 95% CI -6.75 to -1.71, p=0.001), older age (-0.12, 95% CI -0.23 to -0.02, p=0.020), lower education level (overall p<0.001), ethnicity (overall p=0.002), Norwegian nationality (10.27, 95% CI 8.19 to 12.40, p<0.001) and reduced self-reported health status (0.19, 95% CI 0.09 to 0.41, p=0.003) were significantly associated with negative perceptions of generic medicines. There was no evidence to suggest that perceptions of generic medicines moderate the association between sociodemographic and clinical variables and medication adherence (p >= 0.077 for all covariates). Moreover, self-reported medication adherence was high, with 99% scoring at or above the Medication Adherence Report Scale midpoint at both time points. There were no substantial correlations between negative perceptions of generic medicines and medication non-adherence at 2 months (r=0.041, 95% CI 0.002 to 0.081, p=0.037) or 6 months (r=0.038, 95% CI -0.005 to 0.081, p=0.057). Conclusions Mistrust and uncertainty about the safety and efficacy of generic medicines remains in a sizeable proportion of patients after PCI. This applies especially to those of lower socioeconomic status, older age, female sex, immigrants and those with poorer mental health. However, this study demonstrated a shift towards more positive perceptions of generic medicines in the longer term.

  • Lower treatment intensity and poorer survival in metastatic colorectal cancer patients who live alone
  • 2012
  • Ingår i: British Journal of Cancer. - : Springer Science and Business Media LLC. - 0007-0920 .- 1532-1827. ; 107:1, s. 189-194
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Socioeconomic status (SES) and social support influences cancer survival. If SES and social support affects cancer treatment has not been thoroughly explored. METHODS: A cohort consisting of all patients who were initially diagnosed with or who developed metastatic colorectal cancer (mCRC, n = 781) in three Scandinavian university hospitals from October 2003 to August 2006 was set up. Clinical and socioeconomic data were registered prospectively. RESULTS: Patients living alone more often had synchronous metastases at presentation and were less often treated with combination chemotherapy than those cohabitating (HR 0.19, 95% CI 0.04-0.85, P = 0.03). Surgical removal of metastases was less common in patients living alone (HR 0.29, 95% CI 0.10-0.86, P = 0.02) but more common among university-educated patients (HR 2.22, 95% CI 1.10-4.49, P = 0.02). Smoking, being married and having children did not influence treatment or survival. Median survival was 7.7 months in patients living alone and 11.7 months in patients living with someone (P < 0.001). Living alone remained a prognostic factor for survival after correction for age and comorbidity. CONCLUSION: Patients living alone received less combination chemotherapy and less secondary surgery. Living alone is a strong independent risk factor for poor survival in mCRC.

  • Capillary leakage in post-cardiac arrest survivors during therapeutic hypothermia : A prospective, randomised study
  • 2010
  • Ingår i: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine. - : Springer Science and Business Media LLC. - 1757-7241. ; 18, s. 29-
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Fluids are often given liberally after the return of spontaneous circulation. However, the optimal fluid regimen in survivors of cardiac arrest is unknown. Recent studies indicate an increased fluid requirement in post-cardiac arrest patients. During hypothermia, animal studies report extravasation in several organs, including the brain. We investigated two fluid strategies to determine whether the choice of fluid would influence fluid requirements, capillary leakage and oedema formation. Methods: 19 survivors with witnessed cardiac arrest of primary cardiac origin were allocated to either 7.2% hypertonic saline with 6% poly (O-2-hydroxyethyl) starch solution (HH) or standard fluid therapy (Ringer's Acetate and saline 9 mg/ml) (control). The patients were treated with the randomised fluid immediately after admission and continued for 24 hours of therapeutic hypothermia. Results: During the first 24 hours, the HH patients required significantly less i.v. fluid than the control patients (4750 ml versus 8010 ml, p = 0.019) with comparable use of vasopressors. Systemic vascular resistance was significantly reduced from 0 to 24 hours (p = 0.014), with no difference between the groups. Colloid osmotic pressure (COP) in serum and interstitial fluid (p < 0.001 and p = 0.014 respectively) decreased as a function of time in both groups, with a more pronounced reduction in interstitial COP in the crystalloid group. Magnetic resonance imaging of the brain did not reveal vasogenic oedema. Conclusions: Post-cardiac arrest patients have high fluid requirements during therapeutic hypothermia, probably due to increased extravasation. The use of HH reduced the fluid requirement significantly. However, the lack of brain oedema in both groups suggests no superior fluid regimen. Cardiac index was significantly improved in the group treated with crystalloids. Although we do not associate HH with the renal failures that developed, caution should be taken when using hypertonic starch solutions in these patients.

  • Repeated magnetic resonance imaging and cerebral performance after cardiac arrest : a pilot study
  • 2011
  • Ingår i: Resuscitation. - : Elsevier BV. - 0300-9572 .- 1873-1570. ; 82:5, s. 549-555
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM OF THE STUDY: Prognostication may be difficult in comatose cardiac arrest survivors. Magnetic resonance imaging (MRI) is potentially useful in the prediction of neurological outcome, and it may detect acute ischemia at an early stage. In a pilot setting we determined the prevalence and development of cerebral ischemia using serial MRI examinations and neurological assessment. METHODS: Ten witnessed out-of-hospital cardiac arrest patients were included. MRI was carried out approximately 2h after admission to the hospital, repeated after 24h of therapeutic hypothermia and 96 h after the arrest. The images were assessed for development of acute ischemic lesions. Neurophysiological and cognitive tests as well as a self-reported quality-of-life questionnaire, Short Form-36 (SF-36), were administered minimum 12 months after discharge. RESULTS: None of the patients had acute cerebral ischemia on MRI at admission. Three patients developed ischemic lesions after therapeutic hypothermia. There was a change in the apparent diffusion coefficient, which significantly correlated with the temperature (p < 0.001). The neurophysiological tests appeared normal. The patients scored significantly better on SF 36 than the controls as regards both bodily pain (p = 0.023) and mental health (p = 0.016). CONCLUSIONS: MRI performed in an early phase after cardiac arrest has limitations, as MRI performed after 24 and 96 h revealed ischemic lesions not detectable on admission. ADC was related to the core temperature, and not to the volume distributed intravenously. Follow-up neurophysiologic tests and self-reported quality of life were good.

  • Young maternal age at delivery is associated with asthma in adult offspring
  • 2007
  • Ingår i: Respiratory Medicine. - : Elsevier BV. - 0954-6111 .- 1532-3064. ; 101:7, s. 1431-1438
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Some studies have shown an association between lower maternal age at delivery and increased asthma in children and young adults. It is unclear whether this represents an effect of maternal ageing or a protective effect of siblings. In a North-European population based study, we investigated whether mother's age at delivery was associated with risk for asthma and hay fever in adult offspring, taking into account relevant confounders. Methods: A total of 16,190 subjects (74%) aged 23-54yr answered a postal questionnaire in a follow-up of the European Community Respiratory Health Survey (ECRHS I). Results: The associations of maternal age at delivery with hay fever, respiratory symptoms and diagnosed asthma were analysed using logistic regression, adjusting for household size, dwelling, parental education, centre, gender, adult hay fever, smoking, age and body mass index (BMI). The adjusted odds ratios (95% CI) for wheeze with breathlessness, wheeze without a cold and asthma in the offspring were 0.94 (0.90-0.99), 0.89 (0.86-0.94) and 0.92 (0.88-0.97), respectively, per 5yr increase in maternal age. No heterogeneity between centres was found (p = 0.84). The estimates remained similar in sub-sample analyses when adjusting for siblings, maternal smoking (n = 3109) and for birth weight (n = 1686). Hay fever was more common among those with the youngest and oldest mothers. Conclusions: In this large North-European multi-centre study, asthma was less common with increasing maternal age. This effect was consistent between centres and persisted with adjustment for several potential confounders, suggesting that the association may possibly be explained by biological changes related to maternal ageing.

  • Precursors of social emotional functioning among full-term and preterm infants at 12 months: Early infant withdrawal behavior and symptoms of maternal depression
  • 2016
  • Ingår i: Infant Behavior and Development. - : ELSEVIER SCIENCE INC. - 0163-6383 .- 1879-0453. ; 44, s. 159-168
  • Tidskriftsartikel (refereegranskat)abstract
    • This study forms part of a longitudinal investigation of early infant social withdrawal, maternal symptoms of depression and later child social emotional functioning. The sample consisted of a group of full-term infants (N = 238) and their mothers, and a group of moderately premature infants (N = 64) and their mothers. At 3 months, the infants were observed with the Alarm Distress Baby Scale (ADBB) and the mothers completed the Edinburgh Postnatal Depression Scale (EPDS). At 12 months, the mothers filled out questionnaires about the infants social emotional functioning (Infant Toddler Social Emotional Assessment and the Ages and Stages Questionnaire-Social Emotional). At 3 months, as we have previously shown, the premature infants had exhibited more withdrawal behavior and their mothers reported elevated maternal depressive symptoms as compared with the full-born group. At 12 months the mothers of the premature infants reported more child internalizing behavior. These data suggest that infant withdrawal behavior as well as maternal depressive mood may serve as sensitive indices of early risk status. Further, the results suggest that early maternal depressive symptoms are a salient predictor of later child social emotional functioning. However, neither early infant withdrawal behavior, nor gestational age, did significantly predict social emotional outcome at 12 months. It should be noted that the differences in strength of the relations between ADBB and EPDS, respectively, to the outcome at 12 months was modest. An implication of the study is that clinicians should be aware of the complex interplay between early infant withdrawal and signs of maternal postpartum depression in planning ports of entry for early intervention.

  • Sense of coherence—a determinant of quality of life over time in older female acute myocardial infarction survivors
  • 2010
  • Ingår i: Journal of Clinical Nursing. - : John Wiley & Sons. - 0962-1067 .- 1365-2702. ; 19:5-6, s. 820-831
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To determine the relationships between different sense of coherence levels and quality of life, and in older female myocardial infarction survivors; to investigate how socio-demographic, clinical characteristics, sense of coherence self-reported symptoms and function affect quality of life; and to determine whether sense of coherence and quality of life are stable during a six-month follow-up.Background: Myocardinal infraction confers new physical and mental challenges. However, research on sense of coherence and other factors involved in maintaining physical, psychosocial and environmental aspects of quality of life in older female myocardinal infraction survivors is scant.Design: Survey.Methods: A postal survey was conducted of 145 women, aged 62-80 years, three months to five years after myocardial infarction (T1), with a follow-up after six months (T2). Self-reported socio-demographic and clinical data and hospital medical records data were collected. The sense of coherence scale (SOC-29) and the World Health Organization Quality of Life Instrument Abbreviated (WHOQOL-BREF) were used.Results: We found a significant difference in quality of life between weak, moderate, and strong sense of coherence groups (p < 0 center dot 001). Sense of coherence contributed to the level of all quality of life domains (p < 0 center dot 001). Several clinical characteristics contributed to quality of life: (1) physical domain: comorbidities (p < 0 center dot 001), previous myocardial infarction (p = 0 center dot 013), ejection fraction (p < 0 center dot 011), length of hospital stay (p = 0 center dot 005) symptoms and function (p < 0 center dot 001); (2) psychological domain: previous myocardial infarction (p = 0 center dot 031) and symptoms and function (p < 0 center dot 001); and (3) environmental domain: education (p = 0 center dot 033) and symptoms and function (p = 0 center dot 003). On group level, both sense of coherence and quality of life were stable. Experiencing specific health changes (p < 0 center dot 001), not major life events, influenced quality of life during the six-month follow-up.Conclusion: Sense of coherence was an important stable determinant of quality of life domains in female myocardial infarction survivors. Although other factors were identified, further research is needed to elucidate additional determinants of quality of life.Relevance to clinical practice: These specific factors could guide clinicians in making treatment decisions that optimize the quality of life of their patients. Applying a salutogenic perspective through patient education may be important.

  • Clinical trial enrollment, patient characteristics, and survival differences in prospectively registered metastatic colorectal cancer patients
  • 2009
  • Ingår i: Cancer. - : Wiley. - 0008-543X .- 1097-0142. ; 115:20, s. 4679-87
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Trial accrual patterns were examined to determine whether metastatic colorectal cancer (mCRC) patients enrolled in trials are representative of a general cancer population concerning patient characteristics and survival. METHODS: A total of 760 mCRC patients referred for their first oncological consideration at 3 hospitals in Scandinavia covering defined populations were registered consecutively during 2003 to 2006. Clinical trial enrollment, patient characteristics, and treatment were recorded prospectively, and the follow-up was complete. RESULTS: Palliative chemotherapy was initiated in 61% of the patients. Approximately one-third (36%) of patients receiving chemotherapy were included in a trial. The main reason for nonparticipation was failed eligibility criteria (69%). The median survival after chemotherapy was 15.8 months for all patients, and 18 months after combination chemotherapy. Trial patients had better prognostic characteristics and significantly longer survival than nontrial patients: 21.3 months versus 15.2 months when receiving combination chemotherapy. Poor performance status was the main reason for giving best supportive care only, and the median survival was then only 2.1 months. The median survival for all 760 nonresectable mCRC patients was 10.7 months. CONCLUSIONS: mCRC patients enrolled into clinical trials differ in characteristics from patients receiving chemotherapy outside protocol and have better survival, even when given the same treatment. Although trial patients have a median survival close to 2 years, survival is lower for all patients receiving chemotherapy and much lower for all patients diagnosed with mCRC. Studies that better accept the heterogeneity of the population with mCRC are needed.

  • Secondary treatment and predictive factors for second-line chemotherapy after first-line oxaliplatin-based therapy in metastatic colorectal cancer
  • 2007
  • Ingår i: Acta Oncologica. - : Informa UK Limited. - 0284-186X .- 1651-226X. ; 46:7, s. 982-988
  • Tidskriftsartikel (refereegranskat)abstract
    • Two consecutive studies have evaluated the efficacy of oxaliplatin combined with the Nordic bolus schedule of 5-fluorouracil and folinic acid as first-line treatment in metastatic non-resectable colorectal cancer. One hundred and twelve patients were followed after end of first-line treatment and any secondary therapy registered. Fifty-three patients (47%) did not receive second-line irinotecan-based chemotherapy. The main reason was too poor performance status (59%). These patients had a median survival of only 1.7 months after progression of first-line therapy. The best predictive factors at start of first-line chemotherapy for receiving later second-line chemotherapy were performance status and alkaline phosphatase level. Fifty-nine patients (53%) received irinotecan-based second-line therapy. Four (7%) patients had a partial response, and 28 (52%) had stable disease. Median progression-free survival after second-line chemotherapy was 4.1 months and median survival 9.5 months. Median survival after first-line chemotherapy and secondary liver surgery was 34 months and five-year disease-free survival 8%. Survival among patients receiving both first- and second-line chemotherapy was 20.8 months, but only 8.9 months in patients not receiving second-line irinotecan-based chemotherapy. Poor performance status or elevated alkaline phosphatase level at start of first-line chemotherapy predicts whether second-line chemotherapy will be given or not.
