- The aim of this study was to compare the frequency of human leukocyte antigen (HLA) genotypes in 1-18-year-old patients with type 1 diabetes newly diagnosed in 1986-1987 (n = 430), 1996-2000 (n = 342) and in 2003-2005 (n = 171). We tested the hypothesis that the HLA DQ genotype distribution changes over time. Swedish type 1 diabetes patients and controls were typed for HLA using polymerase chain reaction amplification and allele specific probes for DQ A1* and B1* alleles. The most common type 1 diabetes HLA DQA1*-B1*genotype 0501-0201/0301-0302 was 36% (153/430) in 1986-1987 and 37% (127/342) in 1996-2000, but decreased to 19% (33/171) in 2003-2005 (P \ 0.0001). The 0501-0201/0501-0201 genotype increased from 1% in 1986-1987 to 7% in 1996-2000 (P = 0.0047) and to 5% in 2003-2005 (P > 0.05). This study in 1-18-year-old Swedish type 1 diabetes patients supports the notion that there is a temporal change in HLA risk.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Uncomplicated acute type B aortic dissection (AD) treated conservatively has a 10% 30-day mortality and up to 25% need intervention within 4 years. In complicated AD, stent grafts have been encouraging. The aim of the present prospective randomised trial was to compare best medical treatment (BMT) with BMT and Gore TAG stent graft in patients with uncomplicated AD. The primary endpoint was a combination of incomplete/no false lumen thrombosis, aortic dilatation, or aortic rupture at 1 year. Methods: The AD history had to be less than 14 days, and exclusion criteria were rupture, impending rupture, malperfusion. Of the 61 patients randomised, 80% were DeBakey type IIIB. Results: Thirty-one patients were randomised to the BMT group and 30 to the BMT+TAG group. Mean age was 63 years for both groups. The left subclavian artery was completely covered in 47% and in part in 17% of the cases. During the first 30 days, no deaths occurred in either group, but there were three crossovers from the BMT to the BMT TAG group, all due to progression of disease within 1 week. There were two withdrawals from the BMT+TAG group. At the 1-year follow up there had been another two failures in the BMT group: one malperfusion and one aneurysm formation (p = .056 for all). One death occurred in the BMT TAG group. For the overall endpoint BMT+TAG was significantly different from BMT only (p < .001). Incomplete false lumen thrombosis, was found in 13 (43%) of the TAG+BMT group and 30 (97%) of the BMT group (p < .001). The false lumen reduced in size in the BMT+TAG group (p < .001) whereas in the BMT group it increased. The true lumen increased in the BMT TAG (p < .001) whereas in the BMT group it remained unchanged. The overall transverse diameter was the same at the beginning and after 1 year in the BMT group (42.1 mm), but in the BMT+TAG it decreased (38.8 mm; p = .062). Conclusions: Uncomplicated AD can be safely treated with the Gore TAG device. Remodelling with thrombosis of the false lumen and reduction of its diameter is induced by the stent graft, but long term results are needed. (C) 2014 European Society for Vascular Surgery.

Tidskriftsartikel (refereegranskat)abstract
- The rapid administration of optimal antimicrobial treatment is paramount for the treatment of bloodstream infections (BSIs), and rapid antimicrobial susceptibility testing (AST) results are essential. Q-linea has developed the ASTar system, a rapid phenotypic AST device. Here, we report the performance of the ASTar BC G- (Gram-negative) kit when assessed according to the ISO 20776-2:2007 standard for performance evaluation of in vitro diagnostic AST devices. The evaluated ASTar BC G- kit uses a broad panel of 23 antimicrobials for the treatment of BSIs caused by Gram-negative fastidious and nonfastidious bacteria across a range of 6 to 14 2-fold dilutions, including cefoxitin as a screening agent for AmpC-producing Enterobacterales. The ASTar system processes blood culture samples to generate data on MICs and susceptible, intermediate, or resistant (SIR) category. The automated protocol includes concentration determination and concentration adjustment to enable a controlled inoculum, followed by broth microdilution (BMD) and microscopy performed continuously to generate MIC values within approximately 6 h once the test is run on the ASTar system. The performance of the ASTar system was assessed against the ISO 20776-2:2007 standard BMD reference method. Testing was performed across three sites, with results from 412 contrived blood cultures and 74 fresh clinical blood cultures. The ASTar system was also tested for reproducibility, with triplicate testing of 11 strains. The accuracy study comprised 8,650 data points of bacterium-antimicrobial tests. The ASTar system demonstrated an overall essential agreement (EA) of 95.8% (8,283/8,650) and a categorical agreement (CA) of 97.6% (8,433/8,639) compared to the reference BMD method. The overall rate of major discrepancies (MDs) was 0.9% (62/6,845), and that of very major discrepancies (VMDs) was 2.4% (30/1,239). This study shows that the ASTar system delivers reproducible results with overall EA and CA of >95%.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: Neoadjuvant treatment with Trastuzumab-emtansine was associated with similar rates of pathological complete remission (pCR) as standard therapy withd ocetaxel, trastuzumab and pertuzumab in the PREDIX HER2 trial. Here, results of event-free survival (EFS), and pCR rates in key clinical-pathological subgroups and biomarkers including the abundance of stromal tumor infiltrating lymphocytes (TILs) are presented.Methods: PREDIX HER2 is a randomized, multicenter, open-label, phase 2 study involving 9 Swedish sites. Patients with HER2 positive breast cancer, verified by ISH, T>20 mm and/or verified lymph node metastases were randomized to six three-weekly courses of either docetaxel, trastuzumab SC and pertuzumab (group A), or trastuzumab emtansine (T-DM1, group B). Switch of treatment to the opposite arm was allowed in case of lack of response or severe toxicity. Radiological evaluation included 18F-FDG PET/CT. Patients in both groups received adjuvant chemotherapy with epirubicin and cyclophosphamide. TILs were evaluated using standard methodology, median 10%.Results: In total 197 pts. were evaluable, 99 in group A, and 98 in group B. pCR (ypT0/is ypN0) was achieved in 90 pts, 45.7%, with no significant difference between the two treatment groups. pCR rates were lower in the group of patients with hormone receptor (HR)epositive compared with HR-negative tumors but similar in both treatment groups. pCR rates did not differ between the two treatments in subgroups defined by age, menopausal status, tumor grade, T size, node status, HR-status, HER2 status and Ki67. Progressive disease was observed in 3 pts. (3%) during treatment with T-DM1, none in group A. After a median follow-up of 2.4 years 13 EFS events occurred, with no significant differences between the treatment groups. The presence of 10% TILs predicted pCR significantly (p¼0.009), similar in both treatment groups. We also found that a decrease of SUVmax by more than 80% was highly predictive of pCR. HRQoL was significantly better in pts. receiving T-DM1.Conclusions: Our data suggest that neoadjuvant T-DM1 may be as effective as standard neoadjuvant treatment in all clinical subgroups evaluated. Both TILs and PET/CT showed potential to predict pCR.Clinical trial identification: NCT02568839.

- Associations between signs and symptoms from the masticatory system and tinnitus have been reported. The aim of the study was to evaluate the effect of intraoral splint therapy and acupuncture on jaw-muscle tenderness and tinnitus. The study comprised 45 patients (24 men, 21 women; mean age 48 ±12 years) with long standing tinnitus (duration 6.5 ±5.9 years), referred from the audiology department at the University hospital in Örebro, Sweden. A complete audiological survey was performed before referral. Jaw muscles were palpated and the subjective tinnitus evaluated on a 100 mm scale (VAS) at baseline and after one year. All patients received stabilization (Michigan type) splints at start of treatment. After 6 months, non-responders (n=25) were subjected to acupuncture (6 sessions with duration of 30 minutes). Standard statistical methods were used. All patients had tender jaw muscles at palpation. Patients reported a significant decrease of the intensity of tinnitus during the observation period (from 78±20 mm to 52±24 mm after one year; P < 0.001). Only 6 (13 %) of the 45 patients did not report any improvement of their tinnitus. The number of jaw muscles tender to palpation also decreased significantly from 7.9±5.9 to 4.6±5.3; (P < 0.001). In conclusion, all 45 patients with tinnitus had tender jaw muscles. Intraoral splint therapy and acupuncture had a favorable effect on tinnitus and the jaw muscle symptoms. One year after the start of treatment, all but 6 of the 45 patients reported improvement of their tinnitus. Based on the results it is suggested that many tinnitus patients with jaw muscle tenderness can benefit from a treatment including intraoral splint and acupuncture.

Forskningsöversikt (refereegranskat)abstract
- Objective: To assess the diagnostic accuracy of imaging technologies for detecting prostate cancer in patients with elevated PSA-values or suspected findings on clinical examination.Methods: The databases Medline, EMBASE, Cochrane, CRD HTA/DARE/NHS EED and EconLit were searched until June 2013. Pre-determined inclusion criteria were used to select full text articles. Risk of bias in individual studies was rated according to QUADAS or AMSTAR. Abstracts and full text articles were assessed independently by two reviewers. The performance of diagnostic imaging was compared with systematic biopsies (reference standard) and sensitivity and specificity were calculated.Results: The literature search yielded 5141 abstracts, which were reviewed by two independent reviewers. Of these 4852 were excluded since they did not meet the inclusion criteria. 288 articles were reviewed in full text for quality assessment. Six studies, three using MRI and three using transrectal ultrasound were included. All were rated as high risk of bias. Relevant studies on PET/CT were not identified.Conclusion: Despite clinical use, there is insufficient evidence regarding the accuracy of imaging technologies for detecting cancer in patients with suspected prostate cancer using TRUS guided systematic biopsies as reference standard.

Tidskriftsartikel (refereegranskat)abstract
- Background: A systematic repeat biopsy is recommended for men starting on active surveillance for prostate cancer, but the optimal number and distribution of cores are unknown. Objective: To evaluate an extensive repeat transrectal biopsy with anterior sampling in men starting on active surveillance. Design, setting, and participants: Randomised multicentre trial. From 2012 to 2016, 340 Swedish men, aged 40-75 yr, with recently diagnosed low-volume Gleason grade group 1 prostate cancer were included. Intervention: Either an extensive transrectal biopsy with anterior sampling (median 19 cores) or a standard transrectal biopsy (median 12 cores). Outcome measurements and statistical analysis: Primary outcome measure: Gleason grade group >= 2 cancer. Secondary outcomes: Cancer in anteriorly directed biopsy cores and postbiopsy infection. Nonparametric statistical tests were applied. Results and limitations: Gleason grade group >= 2 cancer was detected in 16% of 156 men who had an extensive biopsy and in 10% of 164 men who had a standard biopsy, a 5.7% difference (95% confidence interval [CI]-0.2% to 13%, p = 0.09). There was a strong linear association between prostate-specific antigen (PSA) density and cancer in the anteriorly directed biopsy cores. The odds ratios for cancer in the anteriorly directed cores were for any cancer 2.2 (95% CI 1.3-3.9, p = 0.004) and for Gleason grade group >= 2 cancer 2.3 (95% CI 1.2-4.4, p = 0.015) per 0.1-ng/ml/cm(3) increments. Postbiopsy infections were equally common in the two groups. A limitation is that magnetic resonance imaging was not used. Conclusions: The trial did not support general use of the extensive transrectal repeat biopsy template, but cancer in the anteriorly directed cores was common, particularly in men with high PSA density. The higher the PSA density, the stronger the reason to include anterior sampling at a systematic repeat biopsy. Patient summary: This trial compared two different templates for transrectal prostate biopsy in men starting on active surveillance for low-risk prostate cancer. Cancer was often found in the front part of the prostate, which is not sampled on a standard prostate biopsy. (C) 2019 European Association of Urology. Published by Elsevier B.V. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- IMPORTANCE: Bariatric surgery is a life-changing treatment for patients with severe obesity, but little is known about its association with interpersonal relationships.OBJECTIVES: To investigate if relationship status is altered after bariatric surgery.DESIGN, SETTING, AND PARTICIPANTS: Changes in relationship status after bariatric surgery were examined in 2 cohorts: (1) the prospective Swedish Obese Subjects (SOS) study, which recruited patients undergoing bariatric surgery from September 1, 1987, to January 31, 2001, and compared their care with usual nonsurgical care in matched obese control participants; and (2) participants from the Scandinavian Obesity Surgery Registry (SOReg), a prospective, electronically captured register that recruited patients from January 2007 through December 2012 and selected comparator participants from the general population matched on age, sex, and place of residence. Data was collected in surgical departments and primary health care centers in Sweden. The current analysis includes data collected up until July 2015 (SOS) and December 2012 (SOReg). Data analysis was completed from June 2016 to December 2017.MAIN OUTCOMES AND MEASURES: In the SOS study, information on relationship status was obtained from questionnaires. In the SOReg and general population cohort, information on marriage and divorce was obtained from the Swedish Total Population Registry.RESULTS: The SOS study included 1958 patients who had bariatric surgery (of whom 1389 [70.9%] were female) and 1912 matched obese controls (of whom 1354 [70.8%] were female) and had a median (range) follow-up of 10 (0.5-20) years. The SOReg cohort included 29 234 patients who had gastric bypass surgery (of whom 22 131 [75.6%] were female) and 283 748 comparators from the general population (of whom 214 342 [75.5%] were female), and had a median (range) follow-up of 2.9 (0.003-7.0) years. In the SOS study, the surgical patients received gastric banding (n = 368; 18.8%), vertical banded gastroplasty (n = 1331; 68.0%), or gastric bypass (n = 259; 13.2%); controls received usual obesity care. In SOReg, all 29 234 surgical participants received gastric bypass surgery. In the SOS study, bariatric surgery was associated with increased incidence of divorce/separation compared with controls for those in a relationship (adjusted hazard ratio [aHR] = 1.28; 95% CI, 1.03-1.60; P =.03) and increased incidence of marriage or new relationship (aHR = 2.03; 95% CI, 1.52-2.71; P <.001) in those who were unmarried or single at baseline. In the SOReg and general population cohort, gastric bypass was associated with increased incidence of divorce compared with married control participants (aHR = 1.41; 95% CI, 1.33-1.49; P <.001) and increased incidence of marriage in those who were unmarried at baseline (aHR = 1.35; 95% CI, 1.28-1.42; P <.001). Within the surgery groups, changes in relationship status were more common in those with larger weight loss.CONCLUSIONS AND RELEVANCE: In addition to its association with obesity comorbidities, bariatric surgery-induced weight loss is also associated with changes in relationship status.

Tidskriftsartikel (refereegranskat)abstract
- Background: Attitudes towards the importance of general appearance has varied much not only over time but also among groups of individuals of different age and other characteristics. Whether the situation is similar regarding dental appearance does not seem to have been studied. Purpose: The aim was to study differences in attitudes towards dental appearance between two large samples of 50- and 60-year-old subjects. Materials and Methods: Identical questionnaires were sent to all subjects born in 1942 and 1952 living in two Swedish counties in 2002 (n=17444; n50=8881; n60=8563). The final response rate was 72.2% (n=12599). In this study, responses to four statements on the importance of dental appearance have been analyzed with respect to gender and age. Results: Many of the responses to the four statements differed with gender and age. To the first statement (“To have beautiful and perfect teeth is very important for how you are treated by other people”), 73 % agreed at age 60 compared to 64 % at age 50 (P < 0.001). Approximately 90 % of the subjects agreed to the second statement (“Minor aesthetic imperfections of the teeth have no importance, only they function well”). Logistic regression indicated that several variables were significantly associated with the statements. Besides age and gender, education and self-assessed dental problems were most important. Conclusion: Attitudes towards the importance of dental appearance differed both between genders and age groups. CLINICAL SIGNIFICANCE The varying attitudes towards dental appearance in the population must be acknowledged in treatment decisions.

- Objective: Older adults have not been studied as much as younger ones regarding prevalence of TMD-related symptoms. The aim was to assess the prevalence of TMD-related symptoms in two population samples, 70 and 80 years old.Materials and methods: Identical questionnaires were in 2012 sent to all subjects born in 1932 and 1942 living in two Swedish counties. The response rate was 70.1%, resulting in samples of 5697 70-and 2922 80-year-old subjects. The questionnaire comprised 53 questions. Answers to questions on problems regarding TMD-related symptoms and awareness of bruxism were analysed.Results: Twelve per cent of the women and 7% of the men in the 70-year-old group reported some, rather great or severe problems regarding TMD pain. In the 80-year-olds the prevalence was 8% and 7%, respectively. Subjects who had problems with TMJ sounds reported difficulty to open the jaw wide 6-times and TMJ pain 10-13-times more frequently than subjects without such problems. Changes of taste and awareness of bruxism were the only variables significantly associated with TMD symptoms in both age groups. Number of teeth was not significantly associated with any of the TMD-related symptoms.Conclusions: Most of the elderly subjects had no severe problems with TMD-related symptoms, but 12% of the 70-year-old women reported some, rather great or severe problems. The marked gender difference at age 70 had disappeared in the 80-year-old group. The prevalence was lower among the 80-compared with the 70-year-old subjects of both sexes. The results support the comorbidity between TMD-related symptoms and general health problems.
