  • Rotator Cuff Tears Short- and long-term aspects on treatment outcome
  • 2020
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Rotator cuff tear is a common disorder and there is a lack of knowledge of appropriate treatment and consequences of different treatment modalities. The overall aim of this thesis was to examine short- and long-term results of rotator cuff tear treatment.In Paper I we did a retrospective 21 to 25-year follow-up of a consecutive series of patients with partial and full-thickness rotator cuff tears, treated with acromioplasty without cuff repair. The cuff status had been documented in a specific perioperative protocol in all patients at the index operation. We did x-ray, ultrasonography and clinical scores with Constant score and Western Ontario Rotator Cuff index (WORC) at follow-up. We identified 111 patients with either a partial or a full-thickness tear, but at follow-up 21 were deceased and 11 were too ill from medical conditions unrelated to their shoulder. Out of the remaining 78 eligible patients, 69 were examined (follow-up rate 88 %) and they had a mean age at the index operation of 49 years (range 19-69 years). Forty-five had a partial tear and 24 a full-thickness tear at the index operation. At follow-up, 74% of patients with full-thickness tear had cuff tear arthropathy grade 2 or more according to the arthropathy classification of Hamada (grade 1 to 5) and 87% had developed tear progression (i.e. a larger tear). Corresponding numbers in those with a partial tear was 7 % arthropathy and 42 % tear progression, and the differences between the full-thickness group and the partial tear group was significant for both outcome measures (P<0.001 for both analyses). In those with arthropathy, the mean Constant score was 47 (standard deviation [SD], 23), the mean age and gender-adjusted Constant score 62 (SD, 27) and the mean WORC 58 % (SD, 26). Patients with a partial tear at follow-up had mean Constant score and WORC within the normal range. In multivariable analysis with logistic regression, having a full-thickness tear at the index operation was a risk factor for arthropathy (odds ratio [OR] 37.8; 95% confidence interval [CI], 8.2-175.0) and for tear progression (OR 6.09; 95% CI, 1.41-26.29).In Paper II we examined the contralateral shoulder in the same patients as in paper I and with the same methodology. Sixty-one patients were examined and 38 had had a partial tear at the index operation 21-25 years ago and 23 a full-thickness tear. The overall rate of contralateral full-thickness tears was 50.8 %, which is higher than the 16-35 % rate found in previous studies of newly diagnosed cuff patients. The rate of contralateral full-thickness tear ranged from 13.6 % in patients with a partial tear in the index shoulder at follow-up, to 90 % in patients with a full-thickness tear and arthropathy in the index shoulder. There was a significant correlation regarding conditions between shoulders in the same patient, with a Spearman coefficient of 0.72 for the number of ten-dons with a full-thickness tear, 0.31 for Hamada grade of arthropathy and 0.65 for Constant score. The number of tendons with a full-thickness tear in the index shoulder at follow-up was a risk factor for a contralateral full-thickness tear (OR 3.28; 95% CI, 1.67-6.44) in a multi-variable logistic regression model. We also found that cuff tear arthropathy was significantly more common in patients who had undergone an acromioplasty (P<0.001), a finding which is not confirmatory but may generate a hypothesis.Paper III addressed 17 to 20-year results after operation with a synthetic interposition graft for irreparable cuff tears. We used X-ray, ultrasonography and clinical scores at follow-up. We identified a consecutive series of 13 patients, one of whom was deceased at follow-up. Ten of the remaining 12 participated in a complete follow-up and 2 did only x-ray examination. Nine out of 12 (75 %; 95% CI, 43-95 %) had cuff tear arthropathy Hamada grade 2 or more in the index shoulder at follow-up. The mean Constant score was 46 (SD, 26) and the mean WORC 59 % (SD, 20). Seven out of 12 had contralateral cuff tear arthropathy, and the difference in frequency of arthropathy between shoulders was not statistically significant (P=0.667).In Paper IV we tested whether early repair of small cuff tears, involving mainly supraspinatus, would give a superior clinical result com-pared to physiotherapy without repair in a prospective randomised trial with 12 months follow-up. We used Constant score as the primary out-come, and WORC, EQ-VAS and Numerical Rating Scale for pain (NRS) as secondary outcomes. We also aimed at assessing the rate of tear progression in unrepaired shoulders and the healing rate in repaired shoulders by Magnetic Resonance Imaging (MRI) performed at 12 months. With a high grade of follow-up (100 % for 12 months Constant score and 95 % for 12 months MRI), the repair group had a 12 months median Constant score of 83 (Quartile range [QR], 25) and the conservative group 78 (QR, 22). This between-group difference in medians of 4.5 (95% CI,-5 to 9; P=0.68) was not statistically significant and we did not detect any significant differences in the secondary outcomes at 12 months. The retear rate was 6.5 % in repaired patients and 29 % of unrepaired patients had a tear enlargement >5 mm.The results in this thesis indicate that patients with small, traumatic, full-thickness tears of mainly supraspinatus have no clinical benefit of early surgical repair compared to physiotherapy alone, but in the long-term, patients with full-thickness tears have an increased risk of tear progression, cuff tear arthropathy and low clinical scores. These results are especially important in the treatment decision of repair or not in younger patients. Having a full-thickness tear is also a risk factor for having a contralateral cuff tear, a phenomenon that underlines the importance of endogenous factors in the development of rotator cuff tears. If a cuff tear is not repairable to bone, the addition of a synthetic inter-position graft does not seem to prevent cuff tear arthropathy.

  • Enlarged Training Dataset by Pairwise GANs for Molecular-Based Brain Tumor Classification
  • 2020
  • Ingår i: IEEE Access. - 2169-3536. ; 8:1, s. 22560-22570
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper addresses issues of brain tumor subtype classification using Magnetic Resonance Images (MRIs) from different scanner modalities like T1 weighted, T1 weighted with contrast-enhanced, T2 weighted and FLAIR images. Currently most available glioma datasets are relatively moderate in size, and often accompanied with incomplete MRIs in different modalities. To tackle the commonly encountered problems of insufficiently large brain tumor datasets and incomplete modality of image for deep learning, we propose to add augmented brain MR images to enlarge the training dataset by employing a pairwise Generative Adversarial Network (GAN) model. The pairwise GAN is able to generate synthetic MRIs across different modalities. To achieve the patient-level diagnostic result, we propose a post-processing strategy to combine the slice-level glioma subtype classification results by majority voting. A two-stage course-to-fine training strategy is proposed to learn the glioma feature using GAN-augmented MRIs followed by real MRIs. To evaluate the effectiveness of the proposed scheme, experiments have been conducted on a brain tumor dataset for classifying glioma molecular subtypes: isocitrate dehydrogenase 1 (IDH1) mutation and IDH1 wild-type. Our results on the dataset have shown good performance (with test accuracy 88.82%). Comparisons with several state-of-the-art methods are also included.

  • EVAR of AAA: Long term outcomes, disease progression and risk stratification
  • 2020
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • BackgroundEndovasvular aortic repair (EVAR) is the most commonly utilised technique for the treatment of abdominal aorticaneurysms (AAA) in tertiary referral centers. Detailed long-term outcomes of this technique are relatively scarce,especially for patients presenting symptomatically with AAA. Intra-operatively, proximal type Ia endoleak, involvingblood circulating into the AAA – due to poor proximal seal of the endograft to the aortic neck region – is a fearedcomplication which is usually promptly treated, given its association with post-operative AAA expansion andrupture. Aneurysmatic disease is usually considered a progressive pathology with potential for progression toareas of the aorta beyond the known aneurysmatic segment. Arterial calcifications are established as a marker foratherosclerosis, yet the association of ilio-femoral calcification with post-operative mortality after EVAR is notknown.Aims1. Evaluate the long-term results of EVAR of AAA using a single endograft2. Compare the early and late results of EVAR of symptomatically presenting patients to those treated asymptomatically3. Study the long-term results of intra-operative treatment of type Ia endoleak using large, balloon expandable stents4. Study the progression of aortic disease for patients treated with endovascular means in the postoperative period5. Assess the novel ilio-femoral calcium score as a potential predictor for overall and cardiac-specific mortality after EVARResultsEVAR of AAA yields sustainable results in the long-term, for both symptomatic and asymptomatic patients. Thereis ≈ x4 elevated early mortality in symptomatic patients as compared to asymptomatic ones. Intra-operativetreatment of type Ia endoleaks using large, balloon-expandable stents should be reserved to patients treatedacutely with EVAR. Aortic expansion beyond the sealing zone is relatively uncommon, and seems related to theforce exerted on the aortic wall by the endograft. Ilio-femoral calcium score may predict long-term overall andcardiac mortality after EVAR, albeit the relation is weak. Therefore, further studies are needed to establish thisassociation.

  • Myocardial infarction and peripheral arterial disease: : Treatment patterns and long-term outcome in men and women results from a Swedish nationwide study
  • 2020
  • Ingår i: European Journal of Preventive Cardiology. - SAGE PUBLICATIONS LTD. - 2047-4873.
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Differences in comorbidity, pharmacotherapy, cardiovascular (CV) outcome, and mortality between myocardial infarction (MI) patients and peripheral arterial disease (PAD) patients are not well documented. Aim The aim of this study was to compare comorbidity, treatment patterns, CV outcome, and mortality in MI and PAD patients, focusing on sex differences. Methods This observational, population-based study used data retrieved from mandatory Swedish national registries. The risks of MI and death were assessed by Kaplan-Meier analysis. Secondary preventive drug use was characterized. Cox proportional risk hazard modelling was used to determine the risk of specific events. Results Overall, 91,808 incident MI patients and 52,408 PAD patients were included. CV mortality for MI patients at 12, 24, and 36 months after index was 12.3%, 19.3%, and 25.4%, and for PAD patients it was 15.5%, 23.4%, and 31.0%. At index, 89% of MI patients and 65% of PAD patients used aspirin and 74% and 53%, respectively, used statins. Unlike MI women, women with PAD had a lower rate of other CV-related comorbidities and a lower risk of CV events (age-adjusted hazard ratio 0.81, 95% confidence interval 0.79-0.84), CV death (0.78, 0.75-0.82), and all-cause death (0.78, 0.76-0.80) than their PAD male counterparts. Conclusion PAD patients were less intensively treated and had a higher CV mortality than MI patients. Women with PAD were less likely than men to present with established polyvascular disease, whereas the opposite was true of women with MI. This result indicates that the lower-limb vasculature may more often be the index site for atherosclerosis in women.

  • Item-based analysis of the effects of duloxetine in depression: a patient-level post hoc study.

    • Oft-cited trial-level meta-analyses casting doubt on the usefulness of antidepressants have been based on re-analyses of to what extent the active drug has outperformed placebo in reducing the sum score of the Hamilton Depression Rating Scale (HDRS-17-sum) in clinical trials. Recent studies, however, suggest patient-level analyses of individual HDRS items to be more informative when assessing the efficacy of an antidepressant. To shed further light on both symptom-reducing and symptom-aggravating effects of a serotonin and noradrenaline reuptake inhibitor, duloxetine, when used for major depression in adults, we hence applied this approach to re-analyse data from 13 placebo-controlled trials. In addition, using patient-level data from 28 placebo-controlled trials of selective serotonin reuptake inhibitors (SSRIs), the response profile of duloxetine was compared to that of these drugs. Duloxetine induced a robust reduction in depressed mood that was not dependent on baseline severity and not caused by side-effects breaking the blind. A beneficial effect on depressed mood was at hand already after one week; when outcome was assessed using HDRS-17-sum as effect parameter, this early response was however masked by a concomitant deterioration with respect to adverse event-related items. No support for a suicide-provoking effect of duloxetine was obtained. The response profile of duloxetine was strikingly similar to that of the SSRIs. We conclude that the use of HDRS-17-sum as effect parameter underestimates the true efficacy and masks an early effect of duloxetine on core symptoms of depression. No support for major differences between duloxetine and SSRIs in clinical profile were obtained.

  • Body Mass Index and Association With Caries in School-Aged Children With Orofacial Cleft : A Case-Control Study.
  • 2020
  • Ingår i: The Cleft Palate-Craniofacial Journal. - Sage Publications. - 1055-6656. ; 57:2, s. 169-176
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: Data on the association between body mass index (BMI) and dental caries in children with orofacial clefts are sparse. Therefore, studies on the impact of BMI on caries frequency in children with cleft lip and/or palate (CL/P) are of importance. The aim of the current study was to investigate the association between BMI and frequency of dental caries in children with and without CL/P. Height, weight, and BMI in children with CL/P were also compared to controls.DESIGN: This study used a cross-sectional case-control design.PARTICIPANTS: One hundred and thirty-nine 5- and 10-year-old children with CL/P and 299 age-matched controls.MAIN OUTCOME MEASURES: Caries was recorded according to the International Caries Detection and Assessment System. Height and weight were recorded, and BMI was calculated as weight/height2.RESULTS: There was no correlation between BMI and caries frequency. Weight, height, and BMI were significantly lower in all children with CL/P compared to controls. After adjustment for international adoption, only BMI was significantly lower in CL/P children compared to controls. Non-adopted children with CL/P were significantly heavier and longer than adopted children with CL/P.CONCLUSIONS: Five- and 10-year-old children with corrected CL/P seemed to have a lower BMI than controls, but there was no association between BMI and caries frequency. Internationally adopted children with CL/P were lighter and shorter than non-adopted CL/P children and controls.

  • Endostatin predicts mortality in patients with acute dyspnea – A cohort study of patients seeking care in emergency departments
  • 2020
  • Ingår i: Clinical Biochemistry. - Elsevier. - 0009-9120. ; 75, s. 35-39
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Increased levels of circulating endostatin predicts cardiovascular morbidity and impaired kidney function in the general population. The utility of endostatin as a risk marker for mortality in the emergency department (ED) has not been reported. Aim: Our main aim was to study the association between plasma endostatin and 90-day mortality in an unselected cohort of patients admitted to the ED for acute dyspnea. Design Circulating endostatin was analyzed in plasma from 1710 adults and related to 90-day mortality in Cox proportional hazard models adjusted for age, sex, body mass index, oxygen saturation, respiratory rate, body temperature, C-reactive protein, lactate, creatinine and medical priority according to the Medical Emergency Triage and Treatment System–Adult score (METTS-A). The predictive value of endostatin for mortality was evaluated with receiver operating characteristic (ROC) analysis and compared with the clinical triage scoring system and age. Results: Each one standard deviation increment of endostatin was associated with a HR of 2.12 (95% CI 1.31–3.44 p < 0.01) for 90-day mortality after full adjustment. Levels of endostatin were significantly increased in the group of patients with highest METTS-A (p < 0.001). When tested for the outcome 90-day mortality, the area under the ROC curve (AUC) was 0.616 for METTS-A, 0.701 for endostatin, 0.708 for METTS -A and age and 0.738 for METTS-A, age and levels of endostatin. Conclusions: In an unselected cohort of patients admitted to the ED with acute dyspnea, endostatin had a string association to 90-day mortality and improved prediction of 90-day mortality in the ED beyond the clinical triage scoring system and age with 3%.

    • Exposure to household air pollution has been linked to chronic obstructive pulmonary disease, respiratory symptoms and reduced lung function. This study aims to assess respiratory symptoms and lung function among Ethiopian women in relation to exposure to HAP. We conducted a cross-sectional study among non-smoking women responsible for household cooking. Data was collected on socio-demographic characteristics, respiratory symptoms and risk factors using a validated questionnaire. Spirometry with reversibility testing was performed according to American Thoracic Society/European Respiratory Society guidelines. We used independent t-test and multivariable logistic regression to compare the means and measure association respectively. A total of 545 women participated in the study out of which 231 (42.3%) performed spirometry with at least three acceptable manoeuvres. Everyone in the rural group and 43% of the urban group were exposed to HAP from solid fuels during cooking.

We also found significantly lower forced expiratory volume in the first second (FEV1) (L) among solid fuels users compared with cleaner energy users. Given the larger population settlement in the rural areas and the use of solid fuel as the only energy source, there is a higher risk of developing chronic respiratory health problems for those women in Ethiopia.

  • Community-Based Study of Celiac Disease Autoimmunity Progression in Adults
  • 2020
  • Ingår i: Gastroenterology. - 1528-0012 .- 0016-5085. ; 158:1, s. 151-159
  • Tidskriftsartikel (refereegranskat)abstract
    • Background &amp; Aims: Celiac disease can develop at any age, but outcomes of adults with positive results from serologic tests for tissue transglutaminase antibodies (tTGA) without endoscopic determination of celiac disease (called celiac autoimmunity) have not been thoroughly evaluated. We investigated the proportion of adults with celiac autoimmunity at a community medical center and their progression to celiac disease. Methods: We analyzed waste blood samples from a community clinic from 15,551 adults for tTGA and, if titer results were above 2 U/mL, for endomysial antibody. The blood samples had been collected at 2 time points (median interval, 8.8 years) from 2006 through 2017. We collected data from the clinic on diagnoses of celiac disease based on duodenal biopsy analysis. Results: Of the serum samples collected at the first time point, 15,398 had negative results for tTGA, and 153 had positive results for tTGA (&gt;4 U/mL). Based on medical records, 6 individuals received a diagnosis of celiac disease, for a cumulative incidence of celiac disease diagnosis of 0.06% (95% confidence interval, 0.01–0.11). Forty-nine (0.32%) individuals with a negative result from the first serologic test for tTGA had a positive result from the second test. Among the 153 adults who were tTGA positive at the first time point, 31 (20%) had a subsequent diagnosis of celiac disease, 81 (53%) remained positive for tTGA without a clinical diagnosis of celiac disease, and 41 (27%) had negative test results for tTGA at the second time point. Higher initial tTGA titers, female sex, and a history of hypothyroidism and autoimmune disease were associated with increased risks of subsequent diagnosis of celiac disease. Interestingly, adults whose first blood sample had a positive test result but second blood sample had a negative result for tTGA were older, had lower-than-average initial tTGA titer results, and had a higher mean body mass index than adults whose blood samples were positive for tTGA at both time points and adults later diagnosed with celiac disease. Conclusions: In an analysis of serum samples collected from a community clinic an average of 8.8 years apart, we found that fewer than 1% of adults with negative results from an initial test for tTGA have a positive result on a second test. Of adults with positive results from the test for tTGA, only 20% are later diagnosed with celiac disease; the remaining individuals maintain persistent increases in tTGA without diagnoses of celiac disease or have negative results from second tests.
