  • Patients' perspective on prostatic artery embolization : A qualitative study
  • 2021
  • Ingår i: SAGE Open Medicine. - : SAGE Open. - 2050-3121. ; 9, s. 1-6
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: The aim was to describe the patients' experience of undergoing prostatic artery embolization.Methods: A retrospective qualitative interview study was undertaken with 15 patients of mean age 73 years who had undergone prostatic artery embolization with a median duration of 210 min at two medium sized hospitals in Sweden. The reasons for conducting prostatic artery embolization were clean intermittent catheterization (n = 4), lower urinary tract symptoms (n = 10) or haematuria (n = 1). Data were collected through individual, semi-structured telephone interviews 1-12 months after treatment and analysed using qualitative content analysis.Results: Four categories with sub-categories were formulated to describe the results: a diverse experience; ability to control the situation; resumption of everyday activities and range of opinions regarding efficacy of outcomes. Overall, the patients described the procedure as painless, easy and interesting and reported that while the procedure can be stressful, a calm atmosphere contributed to achieving a good experience. Limitations on access to reliable information before, during and after the procedure were highlighted as a major issue. Practical ideas for improving patient comfort during the procedure were suggested. Improved communications between treatment staff and patients were also highlighted. Most patients could resume everyday activities, some felt tired and bruising caused unnecessary worry for a few. Regarding functional outcome, some patients described substantial improvement in urine flow while others were satisfied with regaining undisturbed night sleep. Those with less effect were considering transurethral resection of the prostate as a future option. Self-enrolment to the treatment and long median operation time may have influenced the results.Conclusions: From the patients' perspective, prostatic artery embolization is a well-tolerated method for treating benign prostate hyperplacia.

  • Acute physiological effects of supramaximal high-intensity interval training in people with or without COPD
  • 2023
  • Ingår i: Medicine & Science in Sports & Exercise. - : Wolters Kluwer. - 0195-9131 .- 1530-0315. ; 55, s. 549-549

    • High-intensity exercise is essential for optimal development of cardiorespiratory fitness and health. This is, however, challenging for most people with chronic obstructive pulmonary disease (COPD) due to ventilatory limitations, leading to exercise at lower intensities accompanied by suboptimal stress on the cardiovascular and muscular system.PURPOSE: To compare the acute effects of a novel concept of short-duration supramaximal high-intensity interval training (HIIT) vs. moderate-intensity continuous training (MICT) in people with COPD and matched healthy controls (HC).METHODS: Sixteen people with mild to severe COPD (75 ± 6 yr; 8 males; 73 ± 13 FEV1%pred; 119 ± 37 W max aerobic power [MAP]) and 14 HC (74 ± 5 yr; 8 males; 106 ± 14 FEV1%pred; 169 ± 38 W MAP) performed HIIT and MICT on a cycle ergometer in a randomized order. HIIT consisted of 10x6s sprints interspersed with 1-min recovery and was performed at two intensities: 60% of max mean power output for 6-sec (MPO6) and 80%MPO6, estimated from the Borg cycle strength test. MICT consisted of 20-min at 60% of MAP, derived from a cardiopulmonary exercise test. Cardiorespiratory parameters, blood lactate concentration, ratings of exertion/symptoms, and exercise modality preference were obtained.RESULTS: Exercise characteristics and physiological data collected at the end of exercise are shown in Table 1. All HIIT sessions were completed, while 1 in 3 people with COPD did not complete MICT. The HIIT modality was preferred by 13/16 (COPD) and 12/14 (HC).CONCLUSION: Short-duration supramaximal HIIT was feasible and enabled a 3.5-fold increase in exercise intensity vs. MICT in people with COPD and HC. Notably, despite the higher exercise intensities, the cardiorespiratory demand during HIIT was similar to MICT and clinically relevant reductions in symptoms were seen in favor of HIIT, in people with COPD. Also, >80% of participants preferred HIIT over MICT.

  • Innovative exercise for optimizing exercise intensity in COPD
  • 2022
  • Ingår i: European Respiratory Journal. - : European Respiratory Society. - 0903-1936 .- 1399-3003. ; 60:Suppl. 66

    • Background: High-intensity exercise is essential for optimal physiological exercise adaptations but challenging to perform for most people with COPD due to ventilatory limitations, leading to use of lower exercise intensities accompanied by suboptimal stress on the cardiovascular and muscular system. This study compared the acute effects of a novel concept of short-duration supramaximal high-intensity interval training (HIIT) vs. traditional moderate-intensity continuous training (MICT) in people with COPD.Methods: Thirteen people with COPD (75±6 yr; 8 males; 72±13 FEV1%pred; 124±37 Wpeak) performed short-duration supramaximal HIIT and MICT on a cycle ergometer in a randomized order. HIIT consisted of 10x6s sprints interspersed with 1-min recovery and was performed at two intensities (HIIT60% & HIIT80%). MICT consisted of 20-min at 60% of CPET Wpeak. Cardiorespiratory parameters, blood lactate concentration, ratings of exertion/symptoms, and exercise modality preference were obtained.Results: Exercise characteristics and physiological data are seen in Table 1. All patients completed HIIT, while 4 out of 13 stopped MICT prematurely. Notably, 85% preferred HIIT over MICT.Conclusion: The novel concept of short-duration supramaximal HIIT enabled a 3 to 4-fold increase in exercise intensity vs. MICT. Notably, the cardiorespiratory demand during HIIT was similar to MICT, and clinically relevant reductions in symptoms were even seen in favor of HIIT.

  • Rituximab in multiple sclerosis : a retrospective observational study on safety and efficacy
  • 2016
  • Ingår i: Neurology. - 0028-3878 .- 1526-632X. ; 87:20, s. 2074-2081
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To investigate the safety and efficacy of rituximab in multiple sclerosis (MS). Methods: In this retrospective uncontrolled observational multicenter study, off-label rituximab-treated patients with MS were identified through the Swedish MS register. Outcome data were collected from the MS register and medical charts. Adverse events (AEs) grades 2-5 according to the Common Terminology Criteria for Adverse Events were recorded. Results: A total of 822 rituximab-treated patients with MS were identified: 557 relapsing-remitting MS (RRMS), 198 secondary progressive MS (SPMS), and 67 primary progressive MS (PPMS). At baseline, 26.2% had contrast-enhancing lesions (CELs). Patients were treated with 500 or 1,000 mg rituximab IV every 6-12 months, during a mean 21.8 (SD 14.3) months. During treatment, the annualized relapse rates were 0.044 (RRMS), 0.038 (SPMS), and 0.015 (PPMS), and 4.6% of patients displayed CELs. Median Expanded Disability Status Scale remained unchanged in RRMS (p = 0.42) and increased by 0.5 and 1.0 in SPMS and PPMS, respectively (p = 0.10 and 0.25). Infusion-related AEs occurred during 7.8% of infusions and most were mild. A total of 89 AEs grades >= 2 (of which 76 infections) were recorded in 72 patients. No case of progressive multifocal leukoencephalopathy was detected. Conclusions: This is the largest cohort of patients with MS treated with rituximab reported so far. The safety, clinical, and MRI findings in this heterogeneous real-world cohort treated with different doses of rituximab were similar to those reported in previous randomized controlled trials on B-cell depletion therapy in MS. Classification of evidence: This study provides Class IV evidence that for patients with MS, rituximab is safe and effective.

  • Kynurenine pathway is altered in patients with SLE and associated with severe fatigue
  • 2018
  • Ingår i: Lupus Science and Medicine. - : BMJ Publishing Group Ltd. - 2053-8790. ; 5:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Fatigue has been reported as the most disturbing symptom in a majority of patients with SLE. Depression is common and often severe. Together these symptoms cause significant morbidity and affect patients with otherwise relatively mild disease. Tryptophan and its metabolites in the kynurenine pathway are known to be important in several psychiatric conditions, for example, depression, which are often also associated with fatigue. We therefore investigated the kynurenine pathway in patients with SLE and controls.Methods: In a cross-sectional design plasma samples from 132 well-characterised patients with SLE and 30 age-matched and gender-matched population-based controls were analysed by liquid chromatography tandem mass spectrometry to measure the levels of tryptophan and its metabolites kynurenine and quinolinic acid. Fatigue was measured with Fatigue Severity Scale and depression with Hospital Anxiety and Depression Scale. SLE disease activity was assessed with Systemic Lupus Erythematosus Disease Activity Index (SLEDAI).Results: The kynurenine/tryptophan ratio, as a measure of indoleamine 2,3-dioxygenase (IDO) activity, was increased in patients with SLE. Patients with active disease (SLEDAI >= 6) showed lower tryptophan levels compared with controls (54 mu M, SD=19 vs 62 mu M, SD=14, p=0.03), although patients with SLE overall did not differ compared with controls. Patients with SLE had higher levels of tryptophan metabolites kynurenine (966 nM, SD=530) and quinolinic acid (546 nM, SD=480) compared with controls (kynurenine: 712 nM, SD=230, p=0.0001; quinolinic acid: 380 nM, SD=150, p=0.001). Kynurenine, quinolinic acid and the kynurenine/tryptophan ratio correlated weakly with severe fatigue (r(s)=0.34, r(s)=0.28 and r(s)=0.24, respectively) but not with depression.Conclusions: Metabolites in the kynurenine pathway are altered in patients with SLE compared with controls. Interestingly, fatigue correlated weakly with measures of enhanced tryptophan metabolism, while depression did not. Drugs targeting enzymes in the kynurenine pathway, for example, IDO inhibitors or niacin (B12) supplementation, which suppresses IDO activity, merit further investigation as treatments in SLE.
