- Objectives: Chronic painful insertional Achilles tendinopathy is known to be difficult to manage. The diagnosis is not always easy because multiple different tissues can be involved. The plantaris tendon has recently been described to frequently be involved in chronic painful mid-portion Achilles tendinopathy. This study aimed to evaluate possible plantaris tendon involvement in patients with chronic painful insertional Achilles tendinopathy.Methods: Ninety-nine consecutive patients (74 males, 25 females) with a mean age of 40 years (range 24-64) who were surgically treated for insertional Achilles tendinopathy, were included. Clinical examination, ultrasound (US)+Doppler examination, and surgical findings were used to evaluate plantaris tendon involvement.Results: In 48/99 patients, there were clinical symptoms of plantaris tendon involvement with pain and tenderness located medially at the Achilles tendon insertion. In all these cases, surgical findings showed a thick and wide plantaris tendon together with a richly vascularised fatty infiltration between the plantaris and Achilles tendon. US examination suspected plantaris involvement in 32/48 patients.Conclusion: Plantaris tendon involvement can potentially be part of the pathology in chronic painful insertional Achilles tendinopathy and should be considered for diagnosis and treatment when there is distinct and focal medial pain and tenderness.Level of evidence: IV case series.

- Objective To describe the injury epidemiology in professional football in South America and compare it with European professional football. Methods Data about football exposures and injury occurrences were registered in Six teams participating in Copa Libertadores in 2016. These teams exposure and injury data were compared with teams participating in the UEFA Elite Club Injury Study during the 2015/2016 and 2016/2017 seasons. Results A total of 271 injuries were reported in the South American cohort representing a training injury incidence of 3.2 (95% CI=2.7 to 3.7) injuries/1000 hours of training exposure and 20.9 (95% CI=17.3 to 25.1) injuries/1000 hours of match exposure. While no differences in muscle injury incidence were observed between South American and European teams, the ligament injury incidence in training among South American teams was significantly higher than European teams (0.6 vs 0.3, RR 1.87, 95% CI 1.21 to 2.87). In addition, a significantly higher proportion of all reported injuries among South American teams than European teams occurred in training. Conclusions A larger proportion of injuries occur in training in South American compared with European professional football. Specifically, ligament injuries in training were more frequent among South American teams.

Is there a role for physical activity interventions in the treatment pathway of bladder cancer? A scoping review of the literature
- 2021
-

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Physical activity (PA) interventions have been introduced in patients with cancer as they may contribute to better treatment outcomes and quality of life (QoL). However, little is known about the impact of PA on patients with bladder cancer (BC). This scoping review aimed to explore efficacy and feasibility of existing PA interventions in the BC care pathway.Methods and analysis: Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review guidelines and the Levac methodology framework were used; electronic databases were searched. Two independent reviewers screened all titles, abstracts and full-text publications for inclusion. The feasibility of integrating a PA intervention in the BC treatment pathway was discussed in a consultation phase with healthcare professionals and patient and public representatives.Results: A total of 675 records were identified through database searching of which 14 studies were included in our scoping review. An additional 17 clinical trials were identified of which 12 were included for which no results have been published yet. The included studies looked at the feasibility of a PA intervention programme, the associations between PA, obesity and BC, but also the determinants of PA engagement for BC patients and the assessment of QoL.Conclusion: This scoping review highlights that despite the general recognition on the role of PA in the BC treatment pathway, there is a gap regarding the understanding of the impact of PA interventions in BC care pathways as well as the limited understanding of factors underlying possible benefits of PA. No clear conclusions could be made regarding structure and processes of PA interventions that may lead to better outcomes. Further PA studies for patients with BC are needed to understand how to incorporate exercise guidelines recommendations.

Forskningsöversikt (refereegranskat)abstract
- To prevent sports injuries, researchers have aimed to understand injury aetiology from both the natural and social sciences and through applying different methodologies. This research has produced strong disciplinary knowledge and a number of injury prevention programmes. Yet, the injury rate continues to be high, especially in youth sport and youth football. A key reason for the continued high injury rate is the development of injury prevention programmes based on monodisciplinary knowledge that does not account for the complex nature of sport injury aetiology. The purpose of this paper is to consider and outline an interdisciplinary research process to research the complex nature of sport injury aetiology. To support our proposition, we first present a narrative review of existing youth football and youth sport injury research demonstrating an absence of paradigmatic integration across the research areas’ main disciplines of biomedicine, psychology and sociology. We then demonstrate how interdisciplinary research can address the complexity of youth sport injury aetiology. Finally, we introduce the interdisciplinary process we have recently followed in a youth football injury research project. While further research is necessary, particularly regarding the integration of qualitative and quantitative sport injury data, we propose that the pragmatic interdisciplinary research process can be useful for researchers who aim to work across disciplines and paradigms and aim to employ methodological pluralism in their research.

- Objectives: The risks associated with achieving a high peak systolic blood pressure (SBP) during clinical exercise testing remain controversial, although this issue has not been evaluated in relation to predicted SBP standards. This cohort study aimed to evaluate the long-term risk of all-cause mortality in males in relation to reference values of peak SBP and the increase in SBP during exercise from the Fitness Registry and the Importance of Exercise: A National Database (FRIEND).Methods: We followed 7164 males (mean age: 58.2±10.6 years) over 95 998 person-years of follow-up (mean 13.4±5.4 years), who performed a maximal treadmill exercise test at baseline. SBP was measured at rest and at peak exercise. Risk of all-cause mortality over 20 years (Cox regression) was determined in relation to reference percentiles of peak SBP and increase in SBP with exercise: <10th (low), 10th-90th, >90th (high) percentiles.Results: A high peak or a large increase in SBP with exercise was not associated with all-cause mortality. Subjects with a low peak SBP had a 20% higher unadjusted risk for all-cause death compared with those with a normal value (1.20 (1.11-1.31)), and a statistically non-significant 7% higher risk after adjustment for all baseline risk factors (1.07 (0.97-1.18)). The corresponding unadjusted and adjusted risks associated with a low increase in SBP were 1.24 (1.15-1.35) and 1.11 (1.02-1.21), respectively.Conclusions: A low-but not high-peak SBP is associated with increased unadjusted risk of all-cause mortality. The FRIEND percentiles of exercise SBP can aid clinicians in individualising risk assessment.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: There is limited research on sex differences in postural orientation (ie, alignment between body segments) in people with knee injury measured with a clinically applicable method. An understanding of the relationship between postural orientation and physical function may help guide decision making in rehabilitation. The aims were to evaluate (1) sex differences in visual assessment of Postural Orientation Errors (POEs) and (2) the association between POEs and objective and patient-reported physical function, in men and women with anterior cruciate ligament reconstruction (ACLR).Methods: Twenty-four women and 29 men (mean 26.7 (SD 6.5) years) with ACLR were included. Six POEs (lower extremity and trunk) were scored from a video of five tasks with varying difficulty to compute POE scores (total and subscores). Objective physical function was evaluated with the single-leg hop for distance and side hop. Patient-reported physical function was evaluated using patient-reported outcome measures (PROMs).Results: Women had significantly more POEs than men (median difference 5.5-25, p≤0.028). More POEs were associated with shorter hop distance and fewer side hops in women (r s = -0.425 to -0.518, p<0.038), but not in men (r s <0.301, p>0.05). No associations were found between POE scores and PROMs, in either sex (r s < -0.246, p>0.05).Conclusions: Women with ACLR seem to have more POEs compared with men, indicating worse postural orientation. More POEs were associated with worse hop performance, suggesting that POE scores may be used as criteria for rehabilitation progression. The lack of associations between POE scores and PROMs indicate that these measures complement each other.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The study aims to make use of individual data to estimate the impact on premature mortality due to both existing commuter bicycling and the potential impact due to increased physical activity through shifting transport mode from car commuting to bicycling.Methods: Using registry data on home and work addresses for the population of Stockholm County the shortest bicycling route on a network of bicycle paths and roads was retrieved. Travel survey data were used to establish current modes of commuting. The relation between duration of bicycling and distance bicycled within the general population in 2015 was established as a basis for identifying individuals that currently drive a car to work but were estimated to have the physical capacity to bicycle to work within 30 min. Within this mode-shift scenario from car-to-bike the duration of bicycling per week was estimated, both among current and potential bicycle commuters. The health impact assessment (HIA) on mortality due to bicycle commuting physical activity was estimated using the same relative risk as within the WHO Health Economic Assessment Tool.Results: The current number of bicycle commuters were 53 000, and the scenario estimated an additional 111 000. Their mean bicycle distances were 4.5 and 3.4 km, respectively. On average these respective amounts of physical activity reduced the yearly mortality by 16% and 12%, resulting in 11.3 and 16.2 fewer preterm deaths per year.Conclusion: The HIA of transferring commuting by car to bicycle estimated large health benefits due to increased physical activity.

- Objective: To investigate the prevalence of mental health problems and satisfaction with life among different groups of elite athletes during a selected period of the COVID-19 pandemic and examine how COVID-19 related consequences were associated with these variables.Design: Cross-sectional data collection during a selected period of the COVID-19 pandemic in Norway.Participants: 378 elite athletes, mean age 26.86 (range 18–59), 159 females and 219 males, divided into Olympic-level and Paralympic-level athletes (n=194) and elite and semielite athletes (n=184).Main outcome measures: Hopkins Symptoms Check List − 10; symptoms of anxiety and depression; Bergen Insomnia Scale; Eating Disorder Examination Questionnaire Short; Canadian Problem Gambling Index and Satisfaction with Life Scale. In addition, we included specific COVID-19 questions (eg, financial concern, keeping daily routines, perceived coping and motivation).Results: Symptoms of insomnia (38.3%) and depression (22.3%) were most prevalent within the sample. Symptoms of eating disorders more prevalent among female athletes (8.8% vs 1.4%) while symptoms of gambling problems were higher among male athletes (8.6% vs 1.3%). Olympic and Paralympic athletes reported lower levels of anxiety and depression symptoms than elite and semielite athletes. Financial concerns were associated with an increased risk of mental health problems, while daily routines and perception of coping were associated with less mental health problems and higher satisfaction with life.Conclusion: Symptoms of insomnia and depression were the two most common mental health problems reported during this selected phase of the COVID-19 pandemic. Elite and semielite athletes reported financial concerns as a risk factor for mental health problems at a larger degree than Olympic and Paralympic athletes. © Author(s) (or their employer(s)) 2021.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To evaluate and compare ratio and allometric scaling models of maximal oxygen consumption (VO2max) for different body size measurements in relation to cardiovascular disease (CVD) incidence and all-cause mortality.Methods: 316 116 individuals participating in occupational health screenings, initially free from CVD, were included. VO2max was estimated using submaximal cycle test. Height, body mass and waist circumference (WC) were assessed, and eight different scaling models (two evaluated in a restricted sample with WC data) were derived. Participants were followed in national registers for first-time CVD event or all-cause mortality from their health screening to first CVD event, death or 31 December 2015.Results: Increasing deciles of VO2max showed lower CVD risk and all-cause mortality for all six models in the full sample (p<0.001) as well as with increasing quintiles in the restricted sample (eight models) (p<0.001). For CVD risk and all-cause mortality, significantly weaker associations with increasing deciles for models 1 (L·min-1) and 5 (mL·min-1·height-2) were seen compared with model 2 (mL·min-1·kg-1), (CVD, p<0.00001; p<0.00001: all-cause mortality, p=0.008; p=0.001) and in some subgroups. For CVD, model 6 (mL·min-1·(kg1·height-1)-1) had a stronger association compared with model 2 (p<0.00001) and in some subgroups.In the restricted sample, trends for significantly stronger associations for models including WC compared with model 2 were seen in women for both CVD and all-cause mortality, and those under 50 for CVD.Conclusion: In association to CVD and all-cause mortality, only small differences were found between ratio scaling and allometric scaling models where body dimensions were added, with some stronger associations when adding WC in the models.
