- Europe represents true diversity, with cultural, linguistic and geopolitical variation spanning a large geographical area. Politics for many of its 750 million inhabitants revolves around the European Union (EU) and its 27 member states. The overarching goal of the EU is to promote peace and the values of the union (inclusion, tolerance, justice, solidarity and non-discrimination).1,2 EFORT was created to connect orthopaedic associations across Europe, fostering relationships between member countries that celebrated diversity and facilitated the exchange of knowledge. Whilst the global landscape changes and politics attempts to interfere in how we live our lives, it is important to remember that a strong organization is a diverse one that evolves over time. Various initiatives exist across the global landscape to support diversity in terms of culture; gender; black, Asian and minority ethnic (BAME) groups; disability groups; lesbian, gay, bisexual, transgender and queer (or questioning) and others (LGBTQ+); and the ‘ageing’ surgeon. This article explores the creation of some of these initiatives and how they have been supported by different orthopaedic organizations. Cite this article: EFORT Open Rev 2020;5:743-752.

- Purpose: Patients with myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, have a propensity to develop acute myeloid leukemia (AML) and myelodysplastic syndromes (MDSs). Using population-based data from Sweden, we assessed the role of MPN treatment and subsequent AML/MDS risk with special focus on the leukemogenic potential of hydroxyurea (HU). Methods: On the basis of a nationwide MPN cohort (N = 11,039), we conducted a nested case-control study, including 162 patients (153 and nine with subsequent AML and MDS diagnosis, respectively) and 242 matched controls. We obtained clinical and MPN treatment data for all patients. Using logistic regression, we calculated odds ratios (ORs) as measures of AML/MDS risk. Results: Forty-one (25%) of 162 patients with MPNs with AML/MDS development were never exposed to alkylating agents, radioactive phosphorous (P32), or HU. Compared with patients with who were not exposed to HU, the ORs for 1 to 499 g, 500 to 999 g, more than 1,000 g of HU were 1.5 (95% CI, 0.6 to 2.4), 1.4 (95% CI, 0.6 to 3.4), and 1.3 (95% CI, 0.5 to 3.3), respectively, for AML/MDS development (not significant). Patients with MPNs who received P32 greater than 1,000 MBq and alkylators greater than 1 g had a 4.6-fold (95% CI, 2.1 to 9.8; P = .002) and 3.4-fold (95% CI, 1.1 to 10.6; P = .015) increased risk of AML/MDS, respectively. Patients receiving two or more cytoreductive treatments had a 2.9-fold (95% CI, 1.4 to 5.9) increased risk of transformation. Conclusion: The risk of AML/MDS development after MPN diagnosis was significantly associated with high exposures of P32 and alkylators but not with HU treatment. Twenty-five percent of patients with MPNs who developed AML/MDS were not exposed to cytotoxic therapy, supporting a major role for nontreatment-related factors. © 2011 by American Society of Clinical Oncology.

- AIM: The aim was to describe the health history of patients after pulmonary oedema and investigate how they perceive their condition and treatment. METHODS: In part one of the study medical records of patients treated for acute pulmonary oedema (n=44) were reviewed regarding social status, health history, medication and cause of the pulmonary oedema. In part two, interviews were performed focusing on the patients' conceptions of the illness, current situation and effects of pulmonary oedema on daily life. RESULTS: One-year mortality was 65% and all but 3 patients had a previous heart diagnosis. Analyses of the interviews yielded five categories: A suffocating feeling; trust in care providers; medication - an annoyance but also a saviour; dealing with existential issues alone or with relatives; concurrent diseases affecting daily life. CONCLUSION: Patients' who experience a pulmonary oedema have several heart-related conditions and a very poor prognosis. Experiencing pulmonary oedema is an anxiety-provoking situation and patients should be regularly and carefully monitored.

- The halide-mediated peroxidase-catalyzed oxidation of ?-carotene was studied as a model system for lipid peroxidation. Of the halide ions tested, Br-, I-, and SCN- all caused some degree of ?-carotene oxidation at pH 7.0 and 4.4. No oxidation was observed with Cl-, however, which is consistent with Cl- not being a substrate for lactoperoxidase. The ?-carotene oxidation caused by the lactoperoxidase-I--H2O2 system was pH dependent, the rate of oxidation being 100-fold higher at pH 4.4 than at pH 7.0. When both I- and SCN- were present, the oxidation rate was reduced. At least partially, this interference between the two substrates was due to competition for the substrate-binding sites on the enzyme. © 1986 American Chemical Society.

- PURPOSE: To explore the associations of severe musculoskeletal injuries (joint and muscles) and surgeries with symptoms of common mental disorders (distress, anxiety/depression, sleeping disturbance, adverse alcohol behaviour , smoking, adverse nutrition behaviour) among male European professional footballers.METHODS: Cross-sectional analyses were conducted on electronic questionnaires completed by professional footballers recruited from the national players' unions of Finland, France, Norway, Spain or Sweden. The number of severe (time loss of more than 28 days) musculoskeletal injuries (total, joint, muscle) and surgeries during a professional football career was examined through four questions, while symptoms of common mental disorders were evaluated through validated scales.RESULTS: A total of 540 professional footballers (mean age of 27 years; 54 % playing in the highest leagues) participated in the study. Sixty-eight per cent of the participants had already incurred one or more severe joint injuries and 60 % one or more severe muscle injuries. Prevalence of symptoms of common mental disorders ranged from 3 % for smoking to 37 % for anxiety/depression and 58 % for adverse nutrition behaviour. The number of severe musculoskeletal injuries during a football career was positively correlated with distress, anxiety and sleeping disturbance, while the number of surgeries was correlated with adverse alcohol behaviour and smoking. Professional footballers who had sustained one or more severe musculoskeletal injuries during their career were two to nearly four times more likely to report symptoms of common mental disorders than professional footballers who had not suffered from severe musculoskeletal injuries.CONCLUSION: It can be concluded that the number of severe musculoskeletal injuries and surgeries during a career is positively correlated and associated with symptoms of common mental disorders among male European professional footballers. This study emphasises the importance of applying a multidisciplinary approach to the clinical care and support of professional footballers, especially when a player faces lengthy periods without training and competition as a consequence of recurrent severe joint or muscle injuries.LEVEL OF EVIDENCE: III.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundPost-traumatic wrist osteoarthritis (OA) can eventually lead to pain, muscular weakness, and stiffness of the wrist, which can affect the function of the entire upper limb and reduce the quality of life. Although there is strong evidence that all patients with OA should be offered adequate education and exercises as a first-line treatment, an effective self-management program, including structured education and therapeutic exercises, has not yet been introduced for individuals with wrist OA. This trial aims to evaluate the effectiveness of an exercise therapy program with joint protective strategies to improve neuromuscular control (intervention group) compared to a training program with range of motion exercises (control group).MethodsThis is a single-blinded randomized controlled trial (RCT) with two treatment arms in patients with symptomatic and radiographically confirmed wrist OA. The trial will be conducted at a hand surgery department. The participants will be randomly assigned either to a neuromuscular exercise therapy program or to a training program with range of motion exercises only. Participants in both groups will receive a wrist orthosis and structured education on wrist anatomy, pathophysiology, and joint protective self-management strategies. The programs consist of home exercises that will be performed twice a day for 12 weeks. The Patient-Rated Wrist Evaluation (PRWE) is the primary outcome measure of pain and function. Wrist range of motion (ROM), grip strength, the Numeric Pain Rating scale (NPRS), Disabilities of the Arm, Shoulder, and Hand (DASH), the General Self-Efficacy Scale (GSES), Global Rating of Change (GROC), and conversion to surgery are the secondary measures of outcome. Assessments will be performed at baseline and at 3, 6, and 12 months after baseline by a blinded assessor.DiscussionThe upcoming results from this trial may add new knowledge about the effectiveness of a self-managed exercise therapy program on pain and function for individuals with wrist OA. If the present self-management program proves to be effective, it can redefine current treatment strategies and may be implemented in wrist OA treatment protocols.Trial registrationClinicalTrials.gov, NCT05367817.

- BackgroundIndividuals with wrist osteoarthritis (OA) can suffer from pain, muscular weakness, and impaired motion of the wrist, which can reduce the quality of life. While there is strong evidence that all patients with OA should receive first-line treatment with education and exercises, this approach has not yet been proposed for individuals with wrist OA. Therefore, this trial aimed to evaluate the effectiveness of a first line neuromuscular joint-protective exercise therapy program compared to a training program with range of motion (ROM) exercises in patients with wrist OA.MethodsIn this randomized controlled trial (RCT), 48 patients with symptomatic and radiographically confirmed wrist OA were randomly allocated to a 12-week self-management program with either a neuromuscular joint-protective exercise therapy program (intervention group) or a training program with ROM exercises only (control group). Our primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) with secondary outcome measures of grip strength, range of wrist motion, the Numerical Pain Rating, Scale (NPRS), the Disabilities of the Arm, Shoulder, and Hand (DASH) and the Generalized Self-Efficacy Scale (GSES). The outcome measures were evaluated by a blinded assessor at baseline and 12 weeks. Between-groups differences were analyzed using the Mann-Whitney U test and within-group differences were analyzed with the Wilcoxon signed-rank test.ResultsA total of 41 participants were analyzed at 12 weeks. There were no significant differences in PRWE between the groups at 12 weeks (p = 0.27). However, DASH improved significantly in the intervention group compared to the control group (p = 0.02) and NPRS on load within the intervention group (p = 0.006). The difference in DASH should be interpreted with caution since it could be due to a non-significant increase (worsening) from baseline in the control group in combination with a non-significant decrease (improvement) in the intervention group.ConclusionsThis RCT showed that the novel neuromuscular joint-protective exercise therapy program was not superior in reducing pain and improving function compared to a training program with ROM exercises at 12 weeks. Future research is warranted to evaluate the effectiveness of forthcoming exercise therapy treatment programs for patients with wrist OA.

Tidskriftsartikel (refereegranskat)abstract
- Background Patient-reported outcome measures (PROMs) are frequently used to assess the effects of treatments in patients with wrist osteoarthritis (OA), but their psychometric properties have not been evaluated in this group of patients. Our aim was to evaluate the psychometric properties of the Numeric Rating Scale (NRS pain at rest, pain on motion without load, and pain on load), the Disabilities of the Arm, Shoulder and Hand (DASH) and the Patient Rated Wrist Evaluation (PRWE) questionnaires in patients with wrist OA regarding test-retest reliability and construct validity. Methods The NRS, DASH and PRWE were self-administered by 50 patients (40 men and 10 women, mean age 66 years) in a postal survey on two occasions, two weeks apart. Test-retest reliability was evaluated by Kappa statistics and the Spearman rank correlation coefficients (rho) were calculated to evaluate construct validity. Results The Kappa coefficients for DASH, PRWE and NRS pain on motion without load and NRS pain on load were > 0.90, 95% CI ranging from 0.84 to 0.98, while NRS pain at rest was 0.83, 95% CI 0.73-0.92. The construct validity of the PROMs was confirmed by three formulated hypotheses: a higher correlation between PRWE and NRS (rho 0.80-0.91, p < 0.001) was found, compared to DASH and NRS (rho 0.68-0.80, p < 0.001); the NRS pain on motion without load and NRS pain on load correlated more strongly to PRWE and DASH (rho 0.71-0.91, p < 0.001) compared to NRS pain at rest (rho 0.68-0.80) and a high correlation between PRWE and DASH was found (rho 0.86, p < 0.001). Conclusions The NRS, DASH and PRWE demonstrate excellent test-retest reliability and moderate to high construct validity in patients with wrist OA. These PROMs are highly related, but they also differ. Therefore, they complement each other in ensuring a comprehensive evaluation of perceived disability in wrist OA. As PRWE showed the highest test-retest reliability and the highest relation to the other PROMs, the sole use of the PRWE can be recommended in clinical practice.

Topical ophthalmic atropine in horses, pharmacokinetics and effect on intestinal motility
- 2021
-
Ingår i: BMC Veterinary Research. - : BioMed Central (BMC). - 1746-6148. ; 17:1

Tidskriftsartikel (refereegranskat)abstract
- Background Topical ophthalmic atropine sulfate is an important part of the treatment protocol in equine uveitis. Frequent administration of topical atropine may cause decreased intestinal motility and colic in horses due to systemic exposure. Atropine pharmacokinetics are unknown in horses and this knowledge gap could impede the use of atropine because of the presumed risk of unwanted effects. Additional information could therefore increase safety in atropine treatment.Results Atropine sulfate (1mg) was administered in two experiments: In part I, atropine sulfate was administered intravenously and topically (manually as eye drops and through a subpalpebral lavage system) to six horses to document atropine disposition. Blood-samples were collected regularly and plasma was analyzed for atropine using UHPLC-MS/MS. Atropine plasma concentration was below lower limit of quantification (0.05 mu g/L) within five hours, after both topical and IV administration. Atropine data were analyzed by means of population compartmental modeling and pharmacokinetic parameters estimated. The typical value was 1.7L/kg for the steady-state volume of distribution. Total plasma clearance was 1.9L/h?kg. The bioavailability after administration of an ophthalmic preparation as an eye drop or topical infusion were 69 and 68%, respectively. The terminal half-life was short (0.8h). In part II, topical ophthalmic atropine sulfate and control treatment was administered to four horses in two dosing regimens to assess the effect on gastro-intestinal motility. Borborygmi-frequency monitored by auscultation was used for estimation of gut motility. A statistically significant decrease in intestinal motility was observed after administration of 1mg topical ophthalmic atropine sulfate every three hours compared to control, but not after administration every six hours. Clinical signs of colic were not observed under any of the treatment protocols.Conclusions Taking the plasma exposure after topical administration into consideration, data and simulations indicate that eye drops administrated at a one and three hour interval will lead to atropine accumulation in plasma over 24h but that a six hour interval allows total washout of atropine between two topical administrations. If constant corneal and conjunctival atropine exposure is required, a topical constant rate infusion at 5 mu g/kg/24h offers a safe alternative.
