  • Long-term pattern of opioid prescriptions after femoral shaft fractures
  • 2016
  • Ingår i: Acta Anaesthesiologica Scandinavica. - Hoboken, USA : Wiley-Blackwell. - 0001-5172 .- 1399-6576. ; 60:5, s. 634-641
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The use of opioids in non-cancer-related pain following skeletal trauma is controversial due to the presumed risk of dose escalation and dependence. We therefore examined the pattern of opioid prescriptions, that is, those actually dispensed, in patients with femoral shaft fractures.Methods: We analysed data from the Swedish National Hospital Discharge Register and the Swedish Prescribed Drug Register between 2005 and 2008.Results: We identified 1471 patients with isolated femoral shaft fractures. The median age was 75 (16-102) years and 56% were female. In this cohort, 891 patients (61%) received dispensed opioid prescriptions during a median follow-up of 20 months (interquartile range 11-32). In the age- and sex-matched comparison cohort (7339 individuals) without fracture, 25% had opioid prescriptions dispensed during the same period. The proportions of patients receiving opioid analgesics at 6 and 12 months after the fracture were 45% (95% CI 42-49) and 36% (32-39), respectively. The median daily morphine equivalent dose (MED) was between 15 and 17 mg 1-12 months post-fracture. After 3 months, less than 5% used prescription doses higher than 20 mg MED per day. Older age (≥ 70 compared with < 70 years) was a significant predictor of earlier discontinuation of opioid use (Hazard ratio [HR] 1.9).Conclusion: A notable proportion of patients continued to receive dispensed prescriptions for opioids for over 6 months (45%) and more than a third of them (36%) continued treatment for at least 12 months. However, the risk of dose escalation seems to be small in opioid-naïve patients.

  • No signs of dose escalations of potent opioids prescribed after tibial shaft fractures : a study of Swedish National Registries
  • 2014
  • Ingår i: BMC Anesthesiology. - London : BioMed Central. - 1471-2253 .- 1471-2253. ; 14, s. 4-
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The pattern of opioid use after skeletal trauma is a neglected topic in pain medicine. The purpose of this study was to analyse the long-term prescriptions of potent opioids among patients with tibial shaft fractures.Methods: Data were extracted from the Swedish National Hospital Discharge Register, the National Pharmacy Register, and the Total Population Register, and analysed accordingly. The study period was 2005-2008.Results: We identified 2,571 patients with isolated tibial shaft fractures. Of these, 639 (25%) collected a prescription for opioids after the fracture. The median follow-up time was 17 (interquartile range [IQR] 7-27) months. Most patients with opioid prescriptions after fracture were male (61%) and the median age was 45 (16-97) years. The leading mechanism of injury was fall on the same level (41%). At 6 and 12 months after fracture, 21% (95% CI 17-24) and 14% (11-17) were still being treated with opioids. Multiple Cox regression-analysis (adjusted for age, sex, type of treatment, and mechanism of injury) revealed that older patients (age >50 years) were more likely to end opioid prescriptions (Hazard ratio 1.5 [95% CI 1.3-1.9]). During follow-up, the frequency of patients on moderate and high doses declined. Comparison of the daily morphine equivalent dose among individuals who both had prescriptions during the first 3 months and the 6th month indicated that the majority of these patients (11/14) did not have dose escalations.Conclusions: We did not see any signs in registry-data of major dose escalations over time in patients on potent opioids after tibial shaft fractures.

  • Global cross-sectional survey on neonatal pharmacologic sedation and analgesia practices and pain assessment tools : impact of the sociodemographic index (SDI)
  • 2024
  • Ingår i: Pediatric Research. - 0031-3998 .- 1530-0447.
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: There is variability in the use of sedatives and analgesics in neonatal intensive care units (NICUs). We aimed to investigate the use of analgesics and sedatives and the management of neonatal pain and distress.Methods: This was a global, prospective, cross-sectional study. A survey was distributed May–November 2022. The primary outcome of this research was to compare results between countries depending on their socio-sanitary level using the sociodemographic index (SDI). We organized results based on geographical location.Results: The survey collected 1304 responses, but we analyzed 924 responses after database cleaning. Responses from 98 different countries were analyzed. More than 60% of NICUs reported having an analgosedation guideline, and one-third of respondents used neonatal pain scales in more than 80% of neonates. We found differences in the management of sedation and analgesia between NICUs on different continents, but especially between countries with different SDIs. Countries with a higher SDI had greater availability of and adherence to analgosedation guidelines, as well as higher rates of analgosedation for painful or distressing procedures. Countries with different SDIs reported differences in analgosedation for neonatal intubation, invasive ventilation, and therapeutic hypothermia, among others.Conclusions: Socio-economic status of countries impacts on neonatal analgosedation management.

  • Diagnostic spirometry in COPD is increasing, a comparison of two Swedish cohorts
  • 2023
  • Ingår i: npj Primary Care Respiratory Medicine. - : Nature Publishing Group. - 2055-1010. ; 33:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Spirometry should be used to confirm a diagnosis of chronic obstructive pulmonary disease (COPD). This test is not always performed, leading to possible misdiagnosis. We investigated whether the proportion of patients with diagnostic spirometry has increased over time as well as factors associated with omitted or incorrectly interpreted spirometry. Data from medical reviews and a questionnaire from primary and secondary care patients with a doctors' diagnosis of COPD between 2004 and 2010 were collected. Data were compared with a COPD cohort diagnosed between 2000 and 2003. Among 703 patients with a first diagnosis of COPD between 2004 and 2010, 88% had a diagnostic spirometry, compared with 59% (p < 0.001) in the previous cohort. Factors associated with not having diagnostic spirometry were current smoking (OR 2.21; 95% CI 1.36-3.60), low educational level (OR 1.81; 1.09-3.02) and management in primary care (OR 2.28; 1.02-5.14). The correct interpretation of spirometry results increased (75% vs 82%; p = 0.010). Among patients with a repeated spirometry, 94% had a persistent FEV1/FVC or FEV1/VC ratio <0.70.

  • Prediction of Mortality Using Different COPD Risk Assessments : A 12-Year Follow-Up
  • 2021
  • Ingår i: The International Journal of Chronic Obstructive Pulmonary Disease. - : Dove Medical Press Ltd.. - 1176-9106 .- 1178-2005. ; 16, s. 665-675
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: A multidimensional approach in the risk assessment of chronic obstructive pulmonary disease (COPD) is preferable. The aim of this study is to compare the prognostic ability for mortality by different COPD assessment systems; spirometric staging, classification by GOLD 2011, GOLD 2017, the age, dyspnea, obstruction (ADO) and the dyspnea, obstruction, smoking, exacerbation (DOSE) indices.Patients and Methods: A total of 490 patients diagnosed with COPD were recruited from primary and secondary care in central Sweden in 2005. The cohort was followed until 2017. Data for categorization using the different assessment systems were obtained through questionnaire data from 2005 and medical record reviews between 2000 and 2003. Kaplan-Meier survival analyses and Cox proportional hazard models were used to assess mortality risk. Receiver operating characteristic curves estimated areas under the curve (AUC) to evaluate each assessment systems´ ability to predict mortality.Results: By the end of follow-up, 49% of the patients were deceased. The mortality rate was higher for patients categorized as stage 3-4, GOLD D in both GOLD classifications and those with a DOSE score above 4 and ADO score above 8. The ADO index was most accurate for predicting mortality, AUC 0.79 (95% CI 0.75-0.83) for all-cause mortality and 0.80 (95% CI 0.75-0.85) for respiratory mortality. The AUC values for stages 1-4, GOLD 2011, GOLD 2017 and DOSE index were 0.73, 0.66, 0.63 and 0.69, respectively, for all-cause mortality.Conclusion: All of the risk assessment systems predict mortality. The ADO index was in this study the best predictor and could be a helpful tool in COPD risk assessment.

  • Hepatitis C virus infection and the temporal trends in the risk of liver cancer : a national register-based cohort study in Sweden
  • 2020
  • Ingår i: Cancer Epidemiology, Biomarkers and Prevention. - : American Association for Cancer Research. - 1055-9965 .- 1538-7755. ; 29:1, s. 63-70
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: In many countries, including Sweden, the birth cohorts with the highest prevalence of hepatitis C virus (HCV) infection have now reached the ages with high risk of primary liver cancer (PLC). The aims were to investigate the temporal trends in PLC incidence and the relative risks of PLC among people diagnosed with HCV-infection between 1990 and 2015.METHODS: The HCV-cohort (n: 52,853) was compared with a matched non-HCV comparison-cohort (n: 523,649). Both the Cancer (CR) and Death registers (DR) were used for follow-up. The crude and age-standardised PLC incidence rates were calculated. The relative risk was estimated as standardized incidence ratios (SIR) and as hazard ratios (HR) using stratified Cox hazards regression.RESULTS: There were 1,609 with PLC-diagnosis in the HCV-cohort, the annual number increased continuously with the crude incidence rate reaching 4.56 per 1,000 person-years in 2013, while remaining low and stable in the comparison-cohort. In the HCV-cohort, the age-standardised PLC incidence rates per 1,000 person-years remained relatively constant at 2.64 (95% CI: 1.54, 3.75) in 2000 and 3.31 (2.51, 4.12) in 2014. The highest SIR was 73 (65.9, 79.5) among those infected for 35-40 years; and the highest HR was 65.9 (55.9, 77.6) for men and 62.2 (31.9, 121.1) for women.CONCLUSIONS: There was a considerable increase in PLC-incidence over time and an extremely high relative risk in the population with HCV-infection for more than 35 years.IMPACT: The national HCV-associated PLC-incidence should be monitored in future studies to evaluate the effect of DAA-treatment.

  • Bi-directional relationships between body mass index and height from three to seven years of age : an analysis of children in the United Kingdom Millennium Cohort Study
  • 2016
  • Ingår i: Longitudinal and Life Course Studies. - London, England : Society for Longitudinal and Life Course Studies. - 1757-9597. ; 7:1, s. 41-52
  • Tidskriftsartikel (refereegranskat)abstract
    • Adiposity and height are known to correlate in childhood but it is less clear whether height and weight gain occur in synergy. We investigate the bidirectional relationships between measures of height and body mass index (BMI) - an indicator of adiposity - and their rates of change. The sample comprises singleton children in the Millennium Cohort Study (N = 11,357). Child anthropometrics measured by trained interviewers at ages three, five and seven years (2003-2009) were transformed to standardised scores based on 1990 British Growth Reference data from which piecewise linear models for height and BMI were jointly fitted. At three years of age, zHeight was positively related to subsequent zBMI velocities, whereas zBMI at three years was positively related to zHeight velocity to age five but inversely related to zHeight velocity from five to seven years of age. Age three zBMI predicted zHeight velocity from three to five years more strongly than age three zHeight predicted zBMI velocity over the same period. The rate of change in zHeight was positively correlated with subsequent zBMI velocity and vice versa. This new evidence on the bidirectional relationships between height and BMI velocities sheds light on the early childhood origins of obesity in adulthood and the need to monitor growth as well as weight gain.

  • Study protocol for a randomized controlled trial with rituximab for psychotic disorder in adults (RCT-Rits)
  • 2023
  • Ingår i: BMC Psychiatry. - : BioMed Central (BMC). - 1471-244X. ; 23:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The role of inflammation in the aetiology of schizophrenia has gained wide attention and research on the association shows an exponential growth in the last 15 years. Autoimmune diseases and severe infections are risk factors for the later development of schizophrenia, elevated inflammatory markers in childhood or adolescence are associated with a greater risk of schizophrenia in adulthood, individuals with schizophrenia have increased levels of pro-inflammatory cytokines compared to healthy controls, and autoimmune diseases are overrepresented in schizophrenia. However, treatments with anti-inflammatory agents are so far of doubtful clinical relevance. The primary objective of this study is to test whether the monoclonal antibody rituximab, directed against the B-cell antigen CD20 ameliorates psychotic symptoms in adults with schizophrenia or schizoaffective disorder and to examine potential mechanisms. A secondary objective is to examine characteristics of inflammation-associated psychosis and to identify pre-treatment biochemical characteristics of rituximab responders. A third objective is to interview a subset of patients and informants on their experiences of the trial to obtain insights that rating scales may not capture.METHODS: A proof-of-concept study employing a randomised, parallel-group, double-blind, placebo-controlled design testing the effect of B-cell depletion in patients with psychosis. 120 participants with a diagnosis of schizophrenia spectrum disorders (SSD) (ICD-10 codes F20, F25) will receive either one intravenous infusion of rituximab (1000 mg) or saline. Psychiatric measures and blood samples will be collected at baseline, week 12, and week 24 post-infusion. Brief assessments will also be made in weeks 2 and 7. Neuroimaging and lumbar puncture, both optional, will be performed at baseline and endpoints. Approximately 40 of the patients and their informants will be interviewed for qualitative analyses on the perceived changes in well-being and emotional qualities, in addition to their views on the research.DISCUSSION: This is the first RCT investigating add-on treatment with rituximab in unselected SSD patients. If the treatment is helpful, it may transform the treatment of patients with psychotic disorders. It may also heighten the awareness of immune-psychiatric disorders and reduce stigma.TRIAL REGISTRATION: NCT05622201, EudraCT-nr 2022-000220-37 version 2.1. registered 14th of October 2022.

  • Determinants in adolescence of stroke-related hospital stay duration in men : a national cohort study
  • 2016
  • Ingår i: Stroke. - Philadelphia, USA : Lippincott Williams & Wilkins. - 0039-2499 .- 1524-4628. ; 47:9, s. 2416-2418
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and purpose: Physical and psychological characteristics in adolescence are associated with subsequent stroke risk. Our aim is to investigate their relevance to length of hospital stay and risk of second stroke.Methods: Swedish men born between 1952 and 1956 (n=237 879) were followed from 1987 to 2010 using information from population-based national registers. Stress resilience, body mass index, cognitive function, physical fitness, and blood pressure were measured at compulsory military conscription examinations in late adolescence. Joint Cox proportional hazards models estimated the associations of these characteristics with long compared with short duration of stroke-related hospital stay and with second stroke compared with first.Results: Some 3000 men were diagnosed with nonfatal stroke between ages 31 and 58 years. Low stress resilience, underweight, and higher systolic blood pressure (per 1-mm Hg increase) during adolescence were associated with longer hospital stay (compared with shorter) in ischemic stroke, with adjusted relative hazard ratios (and 95% confidence intervals) of 1.46 (1.08-1.89), 1.41 (1.04-1.91), and 1.01 (1.00-1.02), respectively. Elevated systolic and diastolic blood pressures during adolescence were associated with longer hospital stay in men with intracerebral hemorrhage: 1.01 (1.00-1.03) and 1.02 (1.00-1.04), respectively. Among both stroke types, obesity in adolescence conferred an increased risk of second stroke: 2.06 (1.21-3.45).Conclusions: Some characteristics relevant to length of stroke-related hospital stay and risk of second stroke are already present in adolescence. Early lifestyle influences are of importance not only to stroke risk by middle age but also to recurrence and use of healthcare resources among stroke survivors.

  • Non-psychotic mental disorders in adolescent men and risk of myocardial infarction : A national cohort study
  • 2020
  • Ingår i: European Heart Journal. - : Oxford University Press. - 0195-668X .- 1522-9645. ; 41:Suppl. 2, s. 2812-2812
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Background/Purpose: Recent studies show that early life stress is associated with later risk of cardiovascular disease (CVD) and stress may also increase the risk of psychiatric disease. We investigated the association between non-psychotic mental disorders in adolescence and subsequent myocardial infarction, and the role of stress resilience and physical fitness in this association.Method: This is a register-based cohort study with 238 013 males born between 1952 and 1956 followed from 1987 to 2010 using information from Swedish registers. Stress resilience was measured at a compulsory military conscription examination using a semi-structured interview with a psychologist. Physical fitness was measured at conscription examination with a cycle ergometer test. A total of 34 503 men were diagnosed with a non-psychotic mental disorder at conscription. Using Cox regression, we estimated the association of mental disorders with myocardial infarction after adjustment for other established CVD risk factors in adolescence. Stress resilience and physical fitness were included in the adjusted model in a second set of analyses.Results: A total of 5891 diagnoses of first myocardial infarction were identified. Non-psychotic mental disorders were associated with an increased risk of myocardial infarction, with a hazard ratio (HR) and confidence interval (CI) of 1.51 (1.41–1.62). The association remained statistically significant after adjustment for other important potential confounders in adolescence such as systolic and diastolic blood pressure, body mass index, inflammation, cognitive function, parental socioeconomic index and a summary disease score (HR 1.24 (CI 1.13–1.35)). The association was further explained by stress resilience and lifestyle factors assessed with a cardiovascular fitness test in adolescence, as the association attenuated but remained statistically significant when further adjusting for stress resilience and physical fitness (HR 1.18 (CI 1.08–1.29)).Conclusion: A non-psychotic mental disorder in adolescences may increase the risk of developing myocardial infarction later in life. This association was partly but not completely explained by poorer stress resilience and physical fitness. Effective prevention might focus on behaviour/lifestyle and psychosocial stress in early life.
