- Abstract
Background: Rupture of extensor pollicis longus tendon (EPL) is a known complication following a distal radius fracture (DRF). Although the precise mechanisms behind these ruptures remain unclear, vascular impairment is thought to play a significant role. Additionally, the impact of an EPL rupture on microstructure of the tendon and muscle is not well understood, but such information could be important in guiding treatment strategies. This study aims to explore the histopathological changes in the EPL tendon and muscle in patients who have experienced an EPL rupture following a DRF., Methods: Consecutive patients with an EPL rupture following a DRF were included and treated with an Extensor Indicis Proprius to EPL tendon transfer. Samples were taken from the distal part of EPL muscle and the proximal tendon from the musculotendinous junction to the rupture site as well as from the tendon distal to the rupture. The tendon specimens were analysed by standard histopathological techniques including immunohistochemistry. In cases of sufficient amount of muscle, fresh frozen specimens were analysed by enzyme- and immuno-histochemistry on cryostat sections., Results: Thirteen patients (12 females, 1 male; median age 61, range 18-72 years) were included in the study. The EPL muscle in all participants showed extensive inflammatory changes, muscle fiber necrosis and regeneration, structural changes in the muscle fibers and slight interstitial fibrosis. The EPL tendon showed profound degenerative changes mainly in the central part of the tendon whereas there were regenerative changes in the periphery of the tendon. The pathological changes were present in all samples regardless of time between the DRF and the EPL rupture or the time between the diagnosis of the rupture and surgery., Conclusions: The extensive inflammatory changes in the EPL muscle indicate that immune mediated mechanisms are involved in muscle degeneration following tendon rupture. The EPL tendon showed characteristic degenerative changes at the myotendinous junction, as well as proximally and distally to the rupture site. The reversibility and the clinical significance of the severe pathological changes seen in the EPL muscle alongside the healing potential of the tendon need further investigation., Trial Registration: Retrospectively registered the 2024-03-15 at Clinicaltrials.gov, ID: NCT06313489., Competing Interests: Declarations. Ethics approval and consent to participate: The study was approved by the Swedish Ethical Review Authority. Diary number: 2022–06845-01.

- Abstract
Purpose: The aim was to longitudinally explore changes in fatigue- and cognition-related symptoms during the first year after hospital treatment for COVID-19., Method: Patients hospitalized for COVID-19 in Gothenburg, Sweden, were consecutively included from 01-07-2020 to 28-02-2021. Patients were assessed at the hospital (acute) and at 3 and 12 months after hospital discharge. Cognition was assessed with the Montreal Cognitive Assessment (MoCA), the Trail Making Test B (TMTB), and the Cognitive Failure Questionnaire (CFQ). Fatigue was assessed using the Multidimensional Fatigue Inventory-20 (MFI-20) and the Mental Fatigue Scale (MFS). Data was analyzed with demographics and changes over time calculated with univariable mixed-effects models., Result: In total, 122 participants were included. Analyzes of Z-scores for MoCA indicated improvement over the year, however the results were 1 SD below norm at all assessments. Alertness (TMTB scores) improved significantly from the acute assessment to the 12- month follow-up (p = <0.001, 95% CI 34.67-69.67). CFQ scores indicated cognitive impairment, and the sum scores for MFI reflected a relatively high degree of fatigue at follow-up., Conclusion: In the first year after hospitalization for COVID-19, most patients experienced fatigue and cognitive impairment. Alertness improved, but improvements in other domains were limited., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Andreasson et al.

- Abstract
Background: Dance classes for people with Parkinson's Disease (PD) are offered worldwide; however, further studies are needed to explore patients' experiences of how dance affects well-being., Purpose: To explore how Dance for Parkinson (Dance for PD) is experienced, and how it contributes to the well-being and health of participants in Sweden., Methods: This qualitative study collected data from four focus groups. Participants were asked how dance classes impacted their well-being, and their ability to perform activities of daily life. The focus groups were recorded and transcribed. Data were analysed using content analysis, meaning units were coded, and codes were coalesced into categories from which themes were abstracted., Results: Dance for PD provided a multifaceted experience related to social relationships, aesthetic context, feelings of wellbeing and the physical experience of dancing. The main theme contained four sub-themes: Connectedness, Pleasure and glamour, Well-being in mind and body and Customized movements., Conclusion: The present study highlights that health and well-being are improved by Dance for PD. It is an enjoyable activity that meets the specific needs of persons living with the consequences of PD and should therefore be promoted by occupational therapists.

- Abstract
The aim of this study was to explore the everyday life experiences of people one year after corrective osteotomy following a symptomatic, malunited, distal radius fracture.Semi-structured interviews were conducted with twenty respondents, median age 65 (22-81) years. The respondents were recruited consecutively. The interviews were subjected to qualitative content analysis. Three authors took part in the analysis.The result is presented as one theme, 'Daily life works again' with five categories: Relief of inconveniences and symptoms, Managing new symptoms and complications, Regaining abilities, Normalised social relationships, Increased wellbeing. The symptoms had declined in severity, some participants regarded themselves as fully restored and used their hand again without hesitation. Others were still bothered by their wrist occasionally and a few had to manage complications. The participants had regained the ability to perform many everyday life activities and reported increased independence and less irritation between spouses, as well as increased wellbeing.One year after a corrective osteotomy following malunion of a distal radius fracture, the patients' experiences represent a continuum. Some are still restricted by their wrist occasionally, the majority experience an increased ease in their performance of activities of daily life and some regard themselves as fully restored. The recovery has a positive impact on social relationships and the patients' wellbeing.

- Abstract
Background: One of the groups that is most vulnerable to the COVID-19 pandemic is pregnant women. They cannot choose to refrain from care; they and their children are at risk of severe complications related to the virus; and they lose comfort and support as clinics prohibit their partners and as societal restrictions demand isolation from friends and relatives. It is urgent to study how this group is faring during the pandemic and we focus here on their health-related worries., Methods: A longitudinal survey at a Swedish hospital starting 6 months before (16 September 2019) and continuing during the COVID-19 outbreak (until 25 August 2020). A total of 6941 pregnant women and partners of diverse social backgrounds were recruited. Ninety-six percent of birth-giving women in the city take early ultrasounds where recruitment took place. Sixty-two percent of the women with an appointment and fifty-one percent of all partners gave consent to participate., Results: Pregnant women experienced dramatically increased worries for their own health, as well as for their partner's and their child's health in the beginning of the pandemic. The worries remained at higher than usual levels throughout the pandemic. Similar, but less dramatic changes were seen among partners., Conclusions: There is a need for heightened awareness of pregnant women's and partners' health-related worries as a consequence of the COVID-19 pandemic. Related feelings, such as anxiety, have been linked to adverse pregnancy outcome and might have long-term effects. The healthcare system needs to prepare for follow-up visits with these families., (© The Author(s) 2020. Published by Oxford University Press on behalf of the European Public Health Association.)

- Abstract
Purpose: The aim of this study was to explore the everyday life experiences of people suffering from a symptomatic, malunited, distal radius fracture. Method: Qualitative interviews were conducted with twenty respondents, median age 59 [16-85] years. The interviews were subjected to qualitative content analysis. Results: The result, presented as one main theme with categories and subcategories, describes the impact of the injury. Everyday life was affected in all participants, very much in a few highly valued activities such as sports and work, whenever the hand was used, or even at rest. This study indicates that the injury has an impact on the ability to move around, other parts of the body, sleep, emotions, self-perception and relationships. It also shows that the patients used several strategies to manage the situation. Conclusion: The malunion of a distal radius fracture has a negative impact on a wide range of daily activities, as well as other aspects of daily life. There is a need for information between caregivers and patients, and clear routines, once a malunion has occurred.Implications for rehabilitationThe symptomatic malunion of a distal radius fracture should be acknowledged as a complex condition requiring comprehensive interventionsTechnical equipment, braces and new solutions on practical problems was necessary to manage everyday life and should be a focus of intervention for this patient groupThe consequences of the injury was not only restricted activity performance but also affected social relationships and emotionsInformation about fracture healing and how a malunion can occur, as well as information on how much the wrist can be loaded at different time points, is important to reduce anxiety.

- Abstract
Purpose: The purpose of this randomised, controlled, double-blind trial was to evaluate functional outcome during the first year after corrective osteotomy for malunited distal radius fractures, with or without filling the osteotomy void., Method: Patients were randomised to receive a HydroSet bone substitute or no graft. Cortical contact was maintained and stabilisation of the osteotomy was carried out with a DiPhos R- or RM Plate. To evaluate subjective functional outcome, the Patient-Rated Wrist Evaluation (PRWE), the Quick Disabilities of the Arm, Shoulder and Hand Questionnaire (Q-DASH), the Canadian Occupational Performance Measure (COPM) and the RAND-36 were used. Moreover, range of motion and grip strength were measured by blinded evaluators. Evaluations were made pre-operatively and three, six and 12 months post-operatively., Results: There were no significant differences between the groups at any time point post-operatively with respect to any of the PROMs that were used or range of motion or grip strength (p > 0.05). In both groups, there was a significant improvement at the 12-month follow-up compared with pre-operatively for the PRWE, the Q-DASH and the COPM satisfaction scores. The RAND-36 revealed no significant differences except for two domains, in which there was an improvement in the treatment group (p < 0.05). For grip strength and for range of motion in all movement directions, except dorsal extension, there was a significant improvement in both groups (p < 0.05)., Conclusion: There is no significant difference in functional outcome during the first year after corrective open-wedge distal radius osteotomy, where cortical contact is maintained, regardless of whether or not bone substitute to fill the void is used.

- Abstract
The aim was to investigate the long-term outcome after corrective osteotomy for malunion of distal radius fractures. Radiological findings, function, activity performance, pain, health-related quality of life and self-efficacy were studied. Evaluation of 37 patients 3-10 years after osteotomy fixated with a volar plate. Conventional radiographs were taken. Grip strength and range of motion were evaluated. Scores from the Patient Rated Wrist Evaluation (PRWE) were compared with normative values. The RAND-36 was used for evaluation of health-related quality of life and the General Self-Efficacy scale (S-GSE) for self-efficacy. Radial height, volar tilt, and ulnar variance improved postoperatively. In the long term, the corrections were maintained. Radiographs showed significantly more advanced osteoarthritis. Mean grip strength was 31 kg (SD 13) 89%, and range of motion varied between 80% and 95% compared to the uninjured side. The median PRWE was 12 points (0-99). The study group experienced higher levels of pain than reference values. There was a moderate correlation between the PRWE and volar tilt (rs = 0.453, p = .006) and grip strength (rs = 0.40, p = .014). At long-term follow-up functional outcome after a corrective osteotomy is generally good, but patients may experience some degree of pain. Corrective osteotomy might be considered for patients with a poor functional outcome after a distal radius fracture.

- Abstract
Objective: To explore patients' and health professionals' views of outpatient rehabilitation services for patients with rheumatoid arthritis in 3 different rheumatology sites across Europe., Methods: A qualitative multi-method study was conducted with patients and health professionals in Vienna (Austria), Gothenburg (Sweden) and Leeds (UK). Data collection was carried out during focus groups with patients and health professionals. Patients' hospital records were integrated into the analysis. Data were analysed for site and findings were compared across sites., Results: A total of 20 patients and 20 health professionals participated in 12 focus groups. Although the 3 sites were all publicly funded university clinics, there were differences between sites regarding the structure and content of rehabilitation services. The themes that emerged in the focus groups were: referrals; continuity in rehabilitation; information provided to patients; patients' organizations; documentation and communication amongst health professionals; interface between primary and specialist care; and prescription practices. Most themes were addressed at all 3 sites, but there were variations in the specifics within themes., Conclusion: Integration of patients' and health professionals' views on how rehabilitation services are coordinated and how (parts of) processes are set up elsewhere provide valuable information for the further optimization of rehabilitation services.

- Abstract
To investigate the potential herd immunity effect of MenAfriVac, a new conjugate vaccine against serogroup A Neisseria meningitidis, a multiple cross-sectional carriage study was conducted in three districts in Burkina Faso in 2009, yielding a total of 20 326 oropharyngeal samples. A major challenge was the harmonisation of operational procedures and ensuring the reliability of results. Here we describe the laboratory quality control (QC) system that was implemented. Laboratory analysis performed by three local laboratories included colony morphology assessment, oxidase test, Gram stain, β-galactosidase activity using o-nitrophenyl-β-galactopyranoside (ONPG), γ-glutamyl transferase (GGT) activity and slide agglutination serogrouping. Internal QC was performed on media, reagents, laboratory equipment and field conditions. Confirmation of results and molecular characterisation was performed at the Norwegian Institute of Public Health (Oslo, Norway). External QC was performed on 3% of specimens where no colonies morphologically resembling N. meningitidis had been identified and on 10% of non-ONPG-/GGT+ isolates. The QC system was a critical element: it identified logistical and operational problems in real time and ensured accuracy of the final data. The overall N. meningitidis carriage prevalence (3.98%) was probably slightly underestimated and the calculated true prevalence was 4.48%. The components of the presented QC system can easily be implemented in any other laboratory study., (Copyright © 2012 Royal Society of Tropical Medicine and Hygiene. All rights reserved.)

- Abstract
Purpose: The aim of this Phase II study was to assess the efficacy and safety of vandetanib in combination with docetaxel in patients with pretreated advanced breast cancer., Methods: The primary study objective was to compare the number of progression events in patients receiving once-daily oral vandetanib (100 mg) in combination with docetaxel (100 mg/m(2) iv every 21 days) versus placebo plus docetaxel. Sixty-four patients were randomized to receive study treatment (n = 35, vandetanib; n = 29, placebo)., Results: A slightly greater number of patients had experienced a progression event by the data cut-off in the vandetanib group (24 [69%]) compared with the placebo group (18 [62%]); HR = 1.19, two-sided 80% CI: 0.79-1.81; two-sided P = 0.59), suggesting that the addition of vandetanib to docetaxel did not affect the risk of disease progression compared with placebo plus docetaxel. The safety and tolerability profile of the combination therapy reflected those of both drugs as monotherapy agents., Conclusions: In patients with advanced breast cancer, vandetanib plus docetaxel was generally well tolerated. Clinical benefit was not different to that observed with placebo plus docetaxel. However, due to the small patient number it was not possible to yield robust results, further research is required to identify predictive factors for patient selection.
