Abstract Background We aimed to investigate the development of synovial fibrosis in vitro and how the fibrosis can be halted. Synovial fibrosis causes joint stiffness in arthritic diseases. The pathway of the fibrotic growth factor, transforming growth factor-beta (TGF-β), has been associated with joint pain in osteoarthritis (OA) and with the fibroid phenotype of rheumatoid arthritis (RA). This suggests that synovial fibrosis, thus accumulation of extracellular matrix (ECM) proteins, plays a role in the clinical manifestations of the diseases. Improving our understanding of fibrotic development may aid in selecting appropriate treatments and development of drugs that can target synovial fibrosis. Methods We isolated primary fibroblast-like synoviocytes (FLS) from the synovial membrane of patients undergoing total knee replacement surgery. To investigate the development of synovial fibrosis, the FLS were cultured in a crowded in vitro model mimicking the ECM. TGF-β1 was used as the fibrotic initiator, the activin receptor-like kinase 5 inhibitor (ALK5i), the anti-fibrotic drug nintedanib, and the anti-inflammatory drug tofacitinib were used as fibrotic inhibitors. The ECM protein formation was quantified in the conditioned media using specific biomarkers of type I, III, and VI collagen formation and fibronectin turnover. Results The TGF-β stimulation inducted fibrogenesis by increasing the biomarkers of fibronectin turnover, type I, III, and VI collagen formation. ALK5i and nintedanib inhibited the TGF-β response across all biomarkers. Tofacitinib trended towards inhibiting TGF-β response with up to 78% inhibition. All the treatments preserved cell viability. Conclusion We have established an in vitro model for assessing fibrogenesis in primary FLS, which can be used to assess the anti-fibrotic effect of multiple drug types. Our study implies that synovial fibrosis can be induced by TGF-β, which additionally can be halted by both direct and indirect inhibition with anti-fibrotic substances. The anti-inflammatory drug tofacitinib also halted the fibrogenesis to some extent; thus, it may exert an anti-fibrotic effect.

Background and purpose: Several studies from the United States report an increased risk of prolonged opioid use after shoulder replacement. We aimed to determine the incidence and risk factors of prolonged opioid use after elective shoulder replacement in a nationwide Danish population. Methods: All primary elective shoulder arthroplasties reported to the Danish Shoulder Arthroplasty Registry (DSR) from 2004 to 2020 were screened for eligibility. Data on potential risk factors was retrieved from the DSR and the National Danish Patient Registry while data on medication was retrieved from the Danish National Health Service Prescription Database. Prolonged opioid use was defined as 1 or more dispensed prescriptions on and 90 days after date of surgery (Q1) and subsequently 1 or more dispensed prescriptions 91–180 days after surgery (Q2). Preoperative opioid use was defined as 1 or more dispensed prescriptions 90 days before surgery. Logistic regression models were used to estimate risk factors for prolonged opioid use. Results: We included 5,660 patients. Postoperatively 1,584 (28%) patients were dispensed 1 or more prescriptions in Q1 and Q2 and were classified as prolonged opioid users. Among the 2,037 preoperative opioid users and the 3,623 non-opioid users, 1,201 (59%) and 383 (11%) respectively were classified as prolonged users. Preoperative opioid use, female sex, alcohol abuse, previous surgery, high Charlson Comorbidity index, and preoperative use of either antidepressants, antipsychotics, or benzodiazepines were associated with increased risk of prolonged opioid use. Conclusion: The incidence of prolonged opioid use was 28%. Preoperative use of opioids was the strongest risk factor for prolonged opioid use, but several other risk factors were identified for prolonged opioid use.

Abstract Taxing sugar-sweetened beverages (SSB) is seen as a win–win situation for governments. It is argued that SSB taxes are relatively easy to implement from a practical perspective compared to for example other nutrition policies. However, the implementation of SSB taxation laws does not happen by itself. Therefore, this work examines implementation processes for SSB taxation in terms of (1) pre-implementation context, (2) taxation instruments used and (3) interactions in the implementation process. Ten databases and grey literature were systematically searched for studies reporting on SSB taxation implementation processes up to February 2020. All studies (N = 1248) were screened independently by two reviewers according to predefined criteria. The selection of variables to be extracted was based on the policy cycle heuristic and informed by intervention implementation research. Information on the process of implementing SSB taxation is limited. Only six cases based on three publications were identified, indicating a gap in this research area. SSB taxation implementation was accomplished by hiring a subcontractor for the implementation or using pre-existing tax collection structures. Political and public support within the implementation process seems to be supportive for the city of Berkeley and for Portugal but was not reported for the Pacific Islands. However, the existing data are very limited, and further research on SSB taxation implementation processes is needed to determine whether the aim of the policy and the envisaged outcome are linked in practice. Registration The protocol was registered with the Open Science Framework (OSF) (osf.io/7w84q/)

Short telomeres might lead to increased risk of Alzheimer’s disease, but observational analyses have been inconclusive and potentially confounded by the strong association of both telomere length and risk of Alzheimer’s disease with age and adverse lifestyle. To circumvent this, analyses including single nucleotide polymorphisms associated with telomere length used in an instrumental variable analysis produces risk estimates likely free of distortions from reverse causation and of most confounding. We tested the hypothesis that short telomeres are associated with increased risk of Alzheimer’s disease, observationally and causal, genetically. Telomere length was measured in 66,567 individuals, and genotyped for rs2487999 in OBFC1, rs7726159 in TERT, and rs1317082 in TERC causing lifelong telomere shortening in 98,146 individuals from two Copenhagen studies. Genetic data on 54,162 individuals from the International Genomics of Alzheimer’s Project were also included. Observationally, multifactorially adjusted hazard ratio for Alzheimer’s disease was 1.02 (95% CI 1.00–1.03) per 200 base pair shorter telomeres. Telomere length was 335 base pairs shorter in individuals with 6 versus 0–1 alleles (p = 5 × 10−105). Genetically, odds ratio for Alzheimer’s disease was 1.08 (1.01–1.16) per 200 base pairs shorter telomeres. Similar results were found in strata of age and comorbidities. In comparative analyses, genetically predicted shorter telomeres were associated with increased risk of myocardial infarction, and with decreased risks of lung cancer and melanoma as previously reported. Short telomeres were associated observationally and causal, genetically with increased risk of Alzheimer’s disease. Telomere biology is therefore a potential pathway involved in the development of Alzheimer’s disease.

The aim of the study is to show whether there are any changes in quality or incidence of complications in total knee arthroplasty (TKA) after establishing a centre for endoprothesis (EPZ).We conducted a retrospective study comparing 100 TKAs one year before establishing an EPZ (Group I) with 100 TKAs one year after establishing an EPZ (group II). Data were collected by analysing our electronic documentation system, and the report of the rehabilitation hospital. The following parameters were documented which are necessary to establish an EPZ: existence of X-rays before and after operation. Existence of full length weight bearing X-ray before operation or using a navigation device. Existence of preoperative planning, duration of TKA below 100 minutes. The following complications were documented: Periprosthetic infections, occurrence of periprosthetic fissures/fractures, thrombembolism, neurologic complications, patients' satisfaction rate with the hospital stay and mortality rate. Additionally femorotibial angle, femoral angle, tibial angle and tibial slope were measured. Statistical analysis was performed with SPSS 22.0. using the Kolmogorov-Smirnov test, the Qui-Square test and the Mann-Whitney U test.There were no statistical differences in local or systemic complications. The mean duration of operation was 82.9 min in group I (min.: 55, max.: 141) und 81.5 min in group II (min.: 57, max.: 129; p 0.05). In group I, there were 20/100 cases (20%) with operation time longer than 100 minutes, in group II 13/100 cases (13%; p 0.001). Analysis of anatomical femorotibial angle, femur angle, tibial angle and tibial slope showed no significant differences. The rate of documented survey of patients' satisfaction rate improved from 62% in group I to 98% in group II (p 0.001).By establishing an EPZ, we achieved a significant improvement in the parameters operation time 100 minutes and documented survey of patients' satisfaction rate, but not in complication rate.Ziel dieser Arbeit ist es, Veränderungen der Qualität bzw.

BACKGROUND Short telomeres are associated with aging and have been associated with a high risk of ischemic heart disease in observational studies; however, the latter association could be due to residual confounding and/or reverse causation. We wanted to test the hypothesis that short telomeres are associated with high risk of ischemic heart disease using a Mendelian randomization approach free of reverse causation and of most confounding. METHODS We genotyped 3 genetic variants in OBFC1 (oligonucleotide/oligosaccharide binding fold containing 1), TERT (telomerase reverse transcriptase), and TERC (telomerase RNA component), which code for proteins and RNA involved in telomere maintenance. We studied 105 055 individuals from Copenhagen; 17 235 of these individuals were diagnosed with ischemic heart disease between 1977 and 2013, and 66 618 had telomere length measured. For genetic studies, we further included the Coronary ARtery DIsease Genome wide Replication and Meta-analysis (CARDIoGRAM) consortium dataset, which included up to 184 967 participants and 60 837 cases of ischemic heart disease. We conducted multivariable adjusted Cox proportional hazard models for observational estimates, using logistic and instrumental variable analysis for genetic estimates. RESULTS Observationally, a 200-bp–shorter telomere length was associated with a multivariable adjusted hazard ratio for ischemic heart disease of 1.02 (95% CI, 1.01–1.03). Per allele, telomeres were shorter by 67 bp (73–60). In meta-analyses of all 4 studies combined, odds ratios for ischemic heart disease were 1.05 (1.03–1.08) for OBCF1, 1.04 (1.02–1.06) for TERT, and 1.01 (0.99–1.03) for TERC. A genetically determined 200-bp–shorter telomere length was associated with an odds ratio for ischemic heart disease of 1.10 (1.06–1.14). CONCLUSIONS Shorter telomeres were associated with a higher risk of ischemic heart disease, both observationally and genetically.

The management of de Quervain’s disease (DD) is nonoperative in the first instance, but surgery should be considered if conservative measures fail. We present the long-term results of operative treatment of DD. From July 1988 to July 1998, 94 consecutive patients with DD were treated operatively by a single surgeon. There were 80 women and 14 men. Average age at the time of operation was 47.4 years (range 22–76). The right wrist was involved in 43 cases, the left in 51 cases. All operations were done under tourniquet control with local infiltration anaesthesia using a longitudinal incision and partial resection of the extensor ligament. There were six perioperative complications, including one superficial wound infection, one delayed wound healing, and four transient lesions of the radial nerve. A successful outcome was achieved in all cases with negative Finkelstein’s test. Simple decompression of both tendons and partial resection of the extensor ligament with a maximum of 3 mm can be recommended in operative treatment of DD with excellent long-term results.

- Abstract
Background and Purpose: Several studies from the United States report an increased risk of prolonged opioid use after shoulder replacement. We aimed to determine the incidence and risk factors of prolonged opioid use after elective shoulder replacement in a nationwide Danish population., Methods: All primary elective shoulder arthroplasties reported to the Danish Shoulder Arthroplasty Registry (DSR) from 2004 to 2020 were screened for eligibility. Data on potential risk factors was retrieved from the DSR and the National Danish Patient Registry while data on medication was retrieved from the Danish National Health Service Prescription Database. Prolonged opioid use was defined as 1 or more dispensed prescriptions on and 90 days after date of surgery (Q1) and subsequently 1 or more dispensed prescriptions 91-180 days after surgery (Q2). Preoperative opioid use was defined as 1 or more dispensed prescriptions 90 days before surgery. Logistic regression models were used to estimate risk factors for prolonged opioid use., Results: We included 5,660 patients. Postoperatively 1,584 (28%) patients were dispensed 1 or more prescriptions in Q1 and Q2 and were classified as prolonged opioid users. Among the 2,037 preoperative opioid users and the 3,623 non-opioid users, 1,201 (59%) and 383 (11%) respectively were classified as prolonged users. Preoperative opioid use, female sex, alcohol abuse, previous surgery, high Charlson Comorbidity index, and preoperative use of either antidepressants, antipsychotics, or benzodiazepines were associated with increased risk of prolonged opioid use., Conclusion: The incidence of prolonged opioid use was 28%. Preoperative use of opioids was the strongest risk factor for prolonged opioid use, but several other risk factors were identified for prolonged opioid use.
