The last years many people have been forcibly displaced due to circumstances such as conflicts in the world, and many people have come to Sweden for shelter. It has been challenging for Swedish society to receive and guide newcomers through the resettlement process, and many organizations in civil society, such as sports clubs, have been invited to support the resettlement. However, a limited numbers of studies has drawn the attention to sports clubs experiences. Therefore the aim of the paper was enhance understanding of sports clubs’ prerequesites and experiences of integration efforts with immigrant children and youth. Ten Swedish clubs with experience of working with newcomers participated. Semi-structured interviews were conducted, and analyzed with qualitative content analysis. Two categories were identified: Struggling with sporting values and organization and Seeing integration in everyday activities. The clubs experienced that integration occurs in everyday activities, but current ideas focusing competition and rigid organization of sports constrained possibilities for integrating newcomers with no or limited former experience of club sports. The clubs experienced potential to contribute to personal development, social connectedness and enjoyment in a new society and building bridges between cultures. In conclusion, clubs cannot solve the challenges of resettlement in society but have potential to be part of larger societal networks of integration.

In Sweden, the formal soccer coach education programs are divided into different levels and are also divided into youth coaching and senior coaching. This paper focuses on youth soccer coaches and their reflections on coach education programs. In the background section the Swedish context is described, as well as current research on coaches’ education and learning. The aim of the paper was to investigate youth soccer coaches’ reflections on coach education programs and to analyse their reflections by using a cultural approach to learning. The empirical material of the paper derives from a web-based questionnaire, posing questions about competence, learning and stress. The coaches were also invited to reflect on the question “how do you believe that soccer associations can educate good coaches?” There were 369 responses, and these were analysed using qualitative content analysis. Results indicated reflections about Flexibility in time, place and content, Mentorship supporting informal learning, Demanding mandatory education and emolument, Education focusing on wholeness and Education being based in practice. The conclusion was that decentralization of education and development of coaches’ contexts, abilities and motivation to critically analyse aims and contents of coach education programs are improvement areas for learning and coaching practices.

The Objectives: The European Commission has highlighted the use of sports as an important venue for engaging citizens in health-enhancing activities, physical activity, volunteerism and active citizenship. Coaching is a central component of sports for children and youth, but there is little research on the promotion of sports coaches’ health. In the light of this gap, the aim of this paper was to elucidate youth soccer coaches’ visions and thoughts regarding leadership support from clubs and soccer associations.

We report a case of a woman with a spontaneous dissection of the left main stem leading to a large aneurysm compressing the left coronary artery. The lesion was initially treated with a conventional multicellular stent. However, persistence of the aneurysm required that two polytetrafluoroethylene-covered stents be implanted. Follow-up angiographic and clinical results were excellent. [ABSTRACT FROM AUTHOR]

Purpose: Vessel recoil is a common phenomenon occurring in the tibial vessels following balloon angioplasty. This study examined the occurrence and short-term impact of acute vessel recoil in a subset of patients treated with retrievable scaffold therapy (RST) via the Spur Peripheral Retrievable Scaffold System (Spur)., Methods: Patients with tibial disease underwent angiography immediately following RST, and then 15 minutes post-treatment. Vessel recoil was defined as a ≥10% decrease in lumen diameter after 15 minutes. Recoil was further analyzed by late lumen loss method, subsegmental late lumen loss method, and smallest segment to same segment method. Patient and vessel characteristics were evaluated. Functional recoil (acute vessel spasm), defined as no significant change in minimal lumen diameter (MLD) at baseline compared with 15 minutes post-treatment, was also evaluated., Results: Of the 38 patients (40 lesions; 33 men [87%]; mean [SD] age 75.3 [8.2] years; 26 (68.4%) with diabetes mellitus); recoil was noted in 42.5% of vessels. Prior to treatment, 13 lesions (32.5%) were total occlusions, the mean lesion length was 64.7±30.4 mm, and 27.5% (11/40) were moderate or severely calcified. Mean treated lesion length was 97.8±39.6 mm. For lesions evaluable by duplex ultrasound, 86.7% of vessels (26/30) were patent at 6 months. There was no significant difference in patency between lesions with recoil and lesions without recoil (81.8% vs 89.5%); there was a trend toward patency in the non-recoil group. Two lesions had functional recoil (acute vessel spasm) and were patent at 6 months. There was no statistically significant correlation of recoil to comorbidities or lesion characteristics, including calcification, for which there was also no correlation to patency., Conclusion: Vessel recoil was noted in 42.5% of vessels treated with RST, whereas previous published rates with balloon angioplasty demonstrated vessel recoil up to 97%, suggesting that RST may impact vessel recoil. This exploratory study did not demonstrate a correlation between vessel recoil and patency at 6 months., Clinical Impact: Retrievable scaffold therapy may replace scoring devices and cutting devices for vessel preparation before definite (drug) therapy. Retrievable scaffold therapy supplements already established vessel preparation strategies in order to follow the concept of leaving nothing behaind. A temporary retrievable scaffold for changing vessel compliance and potentially releasing antiproliferative drugs represents a new interventional concept., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: No conflicts of interest related to this study.

Purpose: This study focuses on higher education as a pathway to establishment in a new society for female immigrants and its role in well-being. Building on previous research that highlights social capital and empowerment as significant factors for successful establishment in a new society, and experiencing well-being, this study aims to explore if higher education can promote female immigrants' establishment in Swedish society., Methods: Interviews were used to explore female immigrants' experiences of higher education and establishment in Swedish society. Thematic analysis was used to analyse the empirical material, generating a nuanced understanding of the studied topic., Results: Higher education was found to promote establishment in Swedish society, ultimately leading to an experience of well-being. Pursuing higher education was perceived as a means of achieving personal fulfilment and success while fostering new social connections. Important factors in pursuing higher education included favourable living conditions, personal motivation, and a positive educational attitude., Conclusion: The study provides insights into female immigrants' higher education experiences in a context that promotes establishment in Swedish society and well-being. However, more research is needed to fully investigate the driving factors for female immigrants pursuing higher education, considering their migrant background and living conditions.

Objective: There is a need for improved outcomes in the endovascular treatment of patients suffering from chronic limb threatening ischaemia (CLTI), highly calcified lesions, and chronic total occlusions (CTOs). The helical centreline self expanding BioMimics 3D stent might be particularly useful in these high risk subsets, combining flexibility and fracture resistance with radial strength. Herein, the performance of the BioMimics 3D stent was assessed in these high risk subsets., Methods: MIMICS-3D is a prospective, multicentre, European real world registry. This was a post hoc analysis, comparing patients with CLTI vs. intermittent claudication (IC), lesions with bilateral calcification vs. those without (peripheral arterial calcium scoring system [PACSS] 3,4 vs. PACSS 0 - 2), and CTO vs. no CTO. Propensity score matching was performed to reduce the impact of baseline variables. The 36 month endpoints were clinically driven target lesion revascularisation (CD-TLR), death, major target limb amputation, and stent patency., Results: A total of 507 patients were enrolled. At 36 months, patients with CLTI had lower freedom from major amputation than patients with IC (92.6% vs. 100%, p < .001). In terms of primary patency, patients with CTO had lower patency rates than those without (63.9% vs. 77.8%, p = .003), but the difference reduced after propensity score matching (70.5% vs. 76.8%, p = .43). Primary patency was not impaired for patients with PACSS 3,4 or patients with CLTI. Freedom from CD-TLR was not significantly different among the groups and was 73.8% for CLTI vs. 78.9% for IC (p = .15), 77.6% for PACSS 3,4 vs. 78.7% for PACSS 0 - 2 (p = .55), and 75.6% for CTO vs. 81.0% for no CTO (p = .11)., Conclusions: The outcome of the MIMICS-3D registry suggests that the BioMimics 3D stent is effective in the endovascular treatment of complex femoropopliteal lesions and in CLTI. Future randomised controlled trials should confirm its non-inferiority or superiority compared with existing alternatives., (Copyright © 2024 The Authors. Published by Elsevier B.V.

Introduction: The preference for using transradial access (TRA) over transfemoral access (TFA) in patients requiring percutaneous coronary intervention (PCI) is based on evidence suggesting that TRA is associated with less bleeding and fewer vascular complications, shorter hospital stays, improved quality of life, and a potential beneficial effect on mortality. We have limited study data comparing the two access routes in a patient population with atrial fibrillation (AF) undergoing PCI, who have a particular increased risk of bleeding, while AF itself is associated with an increased risk of thromboembolism., Methods: Using data from the RIVA-PCI registry, which includes patients with AF undergoing PCI, we analyzed a high-bleeding-risk (HBR) cohort. These patients were predominantly on oral anticoagulants (OAC) for AF, and the PCI was performed via radial or femoral access. Endpoints examined were in-hospital bleeding (BARC 2-5), cerebral events (TIA, hemorrhagic or ischemic stroke) and coronary events (stent thrombosis and myocardial infarction)., Results: Out of 1636 patients, 854 (52.2%) underwent TFA, while 782 (47.8%) underwent the procedure via TRA, including nine patients with brachial artery puncture. The mean age was 75.5 years. Groups were similar in terms of age, sex distribution, AF type, cardiovascular history, risk factors, and comorbidities, except for a higher incidence of previous bypass surgeries, heart failure, hyperlipidemia, and chronic kidney disease (CKD) with a glomerular filtration rate (GFR) < 60 ml/min in the TFA group. No clinically relevant differences in antithrombotic therapy and combinations were present at the time of PCI. However, upon discharge, transradial PCI patients had a higher rate of triple therapy, while dual therapy was preferred after transfemoral procedures. Radial access was more frequently chosen for non-ST-segment elevation myocardial infarction (NSTEMI) and unstable angina pectoris (UAP) cases (NSTEMI 26.6% vs. 17.0%, p < 0.0001; UAP 21.5% vs. 14.5%, p < 0.001), while femoral access was more common for elective PCI (60.3% vs. 44.1%, p < 0.0001). No differences were observed for ST-segment elevation myocardial infarction (STEMI). Both groups had similar rates of cerebral events (TFA 0.2% vs. TRA 0.3%, p = 0.93), but the TFA group had a higher incidence of bleeding (BARC 2-5) (4.2% vs. 1.5%, p < 0.01), mainly driven by BARC 3 bleeding (1.5% vs. 0.4%, p < 0.05). No significant differences were found for stent thrombosis and myocardial infarction (TFA 0.2% vs. TRA 0.3%, p = 0.93; TFA 0.4% vs. TRA 0.1%, p = 0.36)., Conclusions: In HBR patients with AF undergoing PCI for acute or chronic coronary syndrome, the use of TRA might be associated with a decrease in in-hospital bleeding, while not increasing the risk of embolic or ischemic events compared to femoral access. Further studies are required to confirm these preliminary findings., (© 2023. The Author(s).)

Background: Through its helical centreline geometry, the BioMimics 3D vascular stent system is designed for the mobile femoropopliteal region, aiming to improve long-term patency and the risk of stent fractures., Methods: MIMICS 3D is a prospective, European, multi-centre, observational registry to evaluate the BioMimics 3D stent in a real-world population through 3 years. A propensity-matched comparison was performed to investigate the effect of the additional use of drug-coated balloons (DCB)., Results: The MIMICS 3D registry enrolled 507 patients (518 lesion, length 125.9 ± 91.0 mm). At 3 years, the overall survival was 85.2%, freedom from major amputation 98.5%, freedom from clinically driven target lesion revascularisation 78.0%, and primary patency 70.2%. The propensity-matched cohort included 195 patients in each cohort. At 3-year follow-up, there was no statistically significant difference in clinical outcomes, such as overall survival (87.9% in the DCB vs. 85.1% in the no DCB group), freedom from major amputation (99.4% vs. 97.2%), clinically driven TLR (76.4% vs. 80.3%), and primary patency (68.5% vs. 74.4%)., Conclusion: The MIMICS 3D registry showed good 3-year outcomes of the BioMimics 3D stent in femoropopliteal lesions, demonstrating the safety and performance of this device under real-world conditions, whether used alone or in combination with a DCB.

Background: Little is known about current patterns of antithrombotic therapy in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) in clinical practice in Germany., Methods: The RIVA-PCI is a prospective, non-interventional, multicenter study with follow-up until hospital discharge including consecutive patients with AF undergoing PCI., Results: Between January 2018 and March 2020, 1636 patients (elective in 52.6%, non-ST elevation acute coronary syndrome [NSTE-ACS] in 39.3%, ST-elevation myocardial infarction in 8.2%) from 51 German hospitals were enrolled in the study. After PCI a dual antithrombotic therapy (DAT) consisting of OAC and a P2Y12 inhibitor was given to 66.0%, triple antithrombotic therapy (TAT) to 26.0%, dual antiplatelet therapy to 5.5%, and a mono-therapy to 2.5% of the patients. Non-vitamin K antagonist oral anticoagulants (NOACs) were given to 82.4% and vitamin K antagonists to 11.5% of the patients. In-hospital events included death in 12 cases (0.7%), myocardial infarction, stent thrombosis, and ischemic stroke in four (0.2%) patients each, while 2.8% of patients had bleeding complications. The recommended durations for DAT or TAT at discharge were 1 month (1.5%), 3 months (2.1%), 6 months (43.1%), and 12 months (45.6%), with a 6-month course of DAT (47.7%) most often recommended after elective PCI and a 12-month course of DAT (40.1%) after ACS., Conclusion: The preferred therapy after PCI in patients with AF is DAT with a NOAC and clopidogrel. In-hospital ischemic and bleeding events were rare. The recommended durations for combination therapy vary considerably., (© 2022.

Little is known about the efficacy and safety of rivaroxaban in patients with atrial fibrillation (AF) who underwent percutaneous coronary intervention (PCI) in clinical practice. We therefore conducted a prospective observational study to determine the rate of ischemic, embolic, and bleeding events in patients with AF and PCI treated with rivaroxaban in a real-world experience. The RIVA-PCI ("rivaroxaban in patients with AF who underwent PCI") (clinicaltrials.gov NCT03315650) is a prospective, noninterventional, multicenter study with a follow-up until 14 months, including patients with AF who underwent PCI discharged with rivaroxaban. Between January 2018 and March 2020, 700 patients with PCI treated with rivaroxaban (elective in 50.1%, non-ST-elevation acute coronary syndrome 43.0%, ST-elevation myocardial infarction in 6.9%) were enrolled at 51 German hospitals. After PCI, a dual antithrombotic therapy consisting of rivaroxaban and a P2Y12 inhibitor was administered in 70.7% and triple antithrombotic therapy in 27.9%, respectively. Follow-up information could be obtained in 695 patients (99.3%). Rivaroxaban has been stopped prematurely in 21.6% of patients. Clinical events under rivaroxaban during the 14-month follow-up compared with those observed in the PIONEER-AF PCI trial included cardiovascular death (2.0% % vs 2.0%), myocardial infarction (0.9% vs 3.0%), stent thrombosis (0.2% vs 0.8%), stroke (1.3% vs 1.3%), International Society on Thrombosis and Haemostasis major (4.2% vs 3.9%), and International Society on Thrombosis and Haemostasis nonmajor clinically relevant bleeding (15.3% vs 12.9%). Therefore, in this real-world experience, rivaroxaban in patients with AF who underwent PCI is associated with ischemic and bleeding event rates comparable with those observed in the randomized PIONEER-AF PCI trial., Competing Interests: Disclosures Dr. Zeymer: speakers honoraria from AstraZeneca, Bayer, Bristol-Myers Squibb, Boehringer Ingelheim; Daichi Sankyo, Pfizer, Sanofi; Dr. Hennersdorf: speakers honoraria from AstraZeneca, Bayer, Berlin Chemie, Daiichi Sankyo.

This paper explores the lived experiences of LGBTQ migrants participating in a civil society group in Sweden during the migration process and their reflections on the future. Eleven migrants who self-identified as LGBTQ (seven male/gay, one female/lesbian, one female/bi-sexual, and two transgender/gay persons) from three local support groups for LGBTQ migrants agreed to be interviewed. Participants came from Guinea, Iraq, Kurdistan, North Macedonia, Nigeria, Nicaragua, Pakistan, the Russian Federation, Syria, Uganda and Ukraine. Interpretative-phenomenological analysis resulted in three themes: Past: from daily stress to the fear of being killed; Present: safety, belonging and resources to support the transition to a new life; and Future: making a positive difference or being afraid of what's ahead. Participants' health-related journeys and reflections about the future were complex in terms of favourable and unfavourable lived experiences, which become resources and risks for personal development. Study findings offers an enhanced awareness of the complex landscape of, and interaction between, vulnerability and potentiality. Based on the findings, we suggest the adoption of a health promoting approach focusing on the LGBTQ migrants' strengths and personal resources.

(1) Background: The aim was to explore the impact of adaptive responses (resilience factors) on student-athletes' behaviors during a stressful period of life during the SARS-CoV-2-pandemic of 2020 and 2021. (2) Methods: A constructivist-based grounded theory (CGT) was used guided by a biopsychosocial approach. Based on purposeful sampling, 22 male and female student-athletes were divided into four focus group interviews (FGI) seven months after the outbreak of the SARS-CoV-2-pandemic (October 2020) and 18 of these were followed up by FGI seven months later (May 2021). The mean age was 17.65 and they represented golf and handball. (3) Results: The CGT contained four main categories seven months after the SARS-CoV-2-pandemic outbreak: Social support, Self-discipline, Physical practice and recovery and Management of everyday life. Fourteen months after the SARS-CoV-2-pandemic outbreak, four additional main categories emerged: More extensive social support, Belief in the future, Self-awareness and Responsibility and problem-solving. (4) Conclusions: The CTG suggests that student-athletes' favorable adaptations to the stressful SARS-CoV-2-pandemic period 2020-2021 are based on a gradually developed ability to take responsibility for one's own actions, insight into the importance of deepened social interaction, belief in a positive post-COVID future and increased awareness of physical activity and its relation to perceived health.

Purpose: The purpose was to evaluate the safety and efficacy of the Serranator percutaneous transluminal angioplasty serration balloon catheter in patients with infrapopliteal peripheral artery disease., Materials and Methods: A prospective, multicenter, single-arm feasibility study in 46 patients with claudication or chronic limb-threatening ischemia, Rutherford Clinical Category (RCC) 3 to 5, that required treatment of the infrapopliteal arteries above the tibiotalar joint. The primary efficacy outcome was device success-successful insertion, balloon inflation and deflation, and removal of the device(s) with a final diameter stenosis of <50%. The primary safety endpoint was a composite of major adverse limb events (MALE) and perioperative death (POD) through 30 day postprocedure. Other outcomes were change in RCC and ankle-brachial index, wound healing, and clinically-driven target lesion revascularization (CD-TLR). A subset of 9 patients were further evaluated by optical coherence tomography (OCT) or intravascular ultrasound (IVUS) for the presence of serrations in treated lesions. Patient follow-up occurred at 30 days and 6 months., Results: Forty-six patients received treatment with the Serranator device and 55 lesions were treated. Fifty-three lesions were deemed analyzable by the core lab with data and reported hereafter. Device success was 91.7% and freedom from MALE + POD through 30 days was 95.7%. Pretreatment stenosis of 82% was reduced to 21.8% and only 1 lesion (1.9%) required a bailout stent for a grade D dissection. The average maximum balloon inflation pressure was 6 atmospheres. Serrations were present in all treated lesions (n=10) in 9 patients imaged with OCT/IVUS as reviewed by the core laboratory. The RCC score improved by 1 or more level in 70% of patients at 6 months with 42% having a score of 0. The 6 month freedom from CD-TLR was 97.7%., Conclusion: Serranator treatment of infrapopliteal lesions showed excellent lumen gain with minimal evidence of arterial injury and low 6 month CD-TLR. Imaging by IVUS and OCT showed serrations without significant dissection, supporting the device's proposed mechanism of action.

Sweden has an extensive culture of community club sports for children and youths, based on voluntary leadership. Being a voluntary coach can be stressful and can affect coaches' well-being. Since voluntary coaching is closely connected to and conditioned by family life and civil occupation, coaches need support for practical issues as well as for developing their coaching assignment in relation to the constantly changing conditions within sports for children and youths. The aim of this paper was to conceptualize and problematize the supportive structures in everyday activities, in order to promote learning and well-being and to prevent mental health issues. This paper is conceptual and based on a paradigm case. The starting point is communities of practice (CoP) and how CoPs can contribute to the development of supportive structures for coaches in youth sports. In conclusion, a CoP is dependent on negotiation within the coaching team as well as on facilitating factors that can add knowledge, perspectives, and experiences to the CoP. The facilitating factors mean that a CoP has the potential to be health-promoting for both coaches and players. Hence, it is important to create conditions, structures, and support-such as policies, practice-based education, mentorship, and facilitators.

Background: When large numbers of asylum seekers immigrate to a country, civil society is encouraged to contribute to their integration. A subgroup of asylum seekers comprising lesbian, gay, bisexual, transgender, or queer (LGBTQ) refugees are specifically deemed vulnerable to developing health and integration problems due to the double stigma of being a sexual/gender minority and a refugee. The Swedish Federation for LGBTQ Rights (RFSL) is a civil societal organization that has established the support group "RFSL Newcomers," a health-related integration intervention that targets such refugees. The aim of the present study is reconstructing the subjective understanding of health of LGBTQ refugees., Methods: Eleven participants in Newcomers and eight organizers were interviewed about LGBTQ refugees' experiences of migrating and participating in RFSL Newcomers. Qualitative content analysis was used to reconstruct subjective understandings of health that were constructed in these narratives. As the data did not originally concentrate on exploring understandings of health, a broad theoretical approach was used as a heuristic for the analysis, which focused on the common everyday approach of conceptualizing health as wellbeing., Results: The narratives revealed three interconnected, interdependent categories of understanding health in which tensions occur between wellbeing and ill-being: belonging versus alienation, security and safety versus insecurity, and recognition versus denial. The categories contribute to an overarching theme of health as framed freedom - i.e., freedom framed by conditions of society., Conclusions: For our participants, belonging, recognition, and security/safety are conceptual elements of understanding health, not its social determinants. Thus, these understandings emphasize relational and existential meanings of health (theoretical implication). As for practical implications, the understandings of health were connected to being either inside or outside the Newcomers group and a new society, depending on whether LGBTQ refugees comply with social requirements. As a significant actor that is representative of the cultural majority and a facilitator of LGBTQ refugees' resettlement process, RFSL provides LGBTQ refugees with crucial orientations for becoming a "good migrant" and a "good LGBTQ person," yet a "bad bio-citizen." Generally, organizers of interventions may enhance the effectiveness of their interventions when relational, existential, and biomedical understandings of health are all incorporated., (© 2022.

Purpose : Migrants are a vulnerable group concerning health and integration. Civil society organizations are deemed important for the integration and health of migrants and have been encouraged to help. This study explored health and acculturation, as expressed in research into health-related integration interventions for migrant groups provided by civil society organizations. Methods : Databases, journal websites and reference lists were searched in an integrative review. Thirteen articles were found and analysed using concepts of health strategies/perspectives and of acculturation with regard to general and health culture. Results : Studies were divided between two primary spectrums: 1) assimilation-integration and 2) integration-separation spectrum. Spectrum 1 interventions tend to promote assimilation into the present host culture and into a Western view of health. They are mostly driven by representatives of the host culture. Spectrum 2 interventions are characterized by a greater openness concerning the home-culture understandings of health, alongside an appreciation of the home culture in general. They are mostly migrant-driven. Conclusions : The different acculturating approaches in migrant and native-driven civil society organizations call for an awareness of their guiding health and acculturation assumptions and their applied perspectives and strategies. This awareness is considered crucial in order to achieve desired health and acculturation outcomes.

Purpose : This is a study on a sport-based intervention, with a focus on physical activity, social relations, and learning, to promote health and well-being in the workplace lived space. Lived space is situated and associated with social and cultural conventions which affect the quality of the perceived space at work. The aim of the paper is to elucidate the participant's experiences of the intervention and how health and well-being were affected. Methods : The intervention was conducted with employees from the warehouse of a company within the retail sector. The design consisted of one initial workshop as a baseline, a sport-based intervention, three group interviews, and a final workshop. A hermeneutic phenomenological analysis focused on experiences of the intervention and the meaning of the workplace as the lived space. Results : Three themes emerged in the analysis; Expressing positive individual effects, Expressing improved work environment and The meaning of the workplace as lived space . The themes are discussed in relation to three basic health foci: physical activity, social relations and learning. Conclusion : The workplace as a lived space offers a valuable opportunity for sport-based interventions that improve health and well-being through physical activity, social relations, and learning.

Background: The work of a coach can be stressful, and little is known about how volunteer coaches in child and youth soccer perceive stress. Therefore, the overall aim of this study was to explore perceptions of stress among Swedish volunteer youth soccer coaches., Methods: An online questionnaire was distributed to 1514 soccer coaches of which 688 (78% men and 22% women; 4% < 30 years, 34% 31-40 years; 57% 41-50 years and 5% > 51 years) with non-profit positions responded., Results: Findings indicate that participants in general do not feel excessively stressed by being a volunteer youth soccer coach (M = 2.20; SD = 0.93; Min = 1; Max = 5), and no significant differences in perceived stress level were found based on gender, age, ethnicity, educational level or occupation. Multiple regression analysis showed that demands from employment (β = 0.24, p < 0.001), difficulty catching up with the family (β = 0.22, p < 0.001), not having enough time to plan activities (β = 0.13, p < 0.001), feeling pressured when selecting the team (β = 0.09, p = 0.013) and own demands to achieve good results (β = 0.07, p = 0.045), significantly contributed to perceptions of stress among the investigated youth sport coaches., Conclusions: The results shed light on the important aim that sport clubs develop holistic strategies when recruiting and retaining coaches and for other functions concerning child and youth soccer teams.

Purpose: To report the 12-month safety and efficacy outcomes of the investigational device exemption trial evaluating an implantable below-the-knee (BTK) dissection repair device. Materials and Methods: The prospective, multicenter, single-arm Tack-Optimized Balloon Angioplasty (TOBA) II BTK study ( ClinicalTrials.gov identifier NCT02942966) evaluated the Tack Endovascular System in the BTK arteries vs objective performance goals derived from a systematic review of BTK angioplasty literature. Patients presenting with Rutherford category 3-5 ischemia were eligible and were enrolled during the procedure if angioplasty resulted in dissection(s) of the BTK arteries. Between February 2017 and December 2018, the study enrolled 233 patients (mean age 74.4±10.0 years; 157 men). Most lesions (93.8%) were de novo; almost half (118/248, 47.6%) were total occlusions. Mean target lesion length was 80±49 mm. Moderate to severe calcium was present in 89 (35.8%) lesions. The 30-day primary safety endpoint was a composite of major adverse limb events (MALE) and all-cause perioperative death (POD). The primary efficacy endpoint was a composite of MALE at 6 months and 30-day POD. These safety and efficacy endpoints were assessed at 12 months as observational endpoints along with amputation-free survival (AFS), freedom from clinically-driven target lesion revascularization (CD-TLR), vessel patency, and changes from baseline in clinical and quality of life measures. Results: All patients had post-PTA dissection and received at least 1 Tack implant (range 1 to 16). The angiographic core laboratory noted successful resolution of 100% of the 341 treated dissections. At 12 months, 93.4% (170/182) of patients remained free of the composite endpoint of MALE + POD. Tacked segment patency was 81.3% and limb salvage was 96.8% at 12 months; freedom from CD-TLR and AFS were 83.1% and 89.3%, respectively. Sustained Rutherford category improvement was reported in 82.4% of evaluated patients, with 62.4% improving ≥3 categories (p<0.001). Ninety of 124 index wounds (72.5%) healed or improved. Conclusion: The Tack Endovascular System is safe and effective in the treatment of post-angioplasty BTK dissections. Twelve-month outcome data from the TOBA II BTK study demonstrate high rates of patency, limb salvage, and wound healing.

The aim of this study was to elucidate Finnish, Norwegian, Russian and Swedish students' reflections and ideas on how interactive technology can be used to promote health in school. The data were collected in the northern part of these four countries, and 630 students aged 13-15 filled out the World Health Organization's 'Health Behavior in School-Aged Children' self-completion questionnaire with one additional open question, which is analyzed in this article (n = 419). The phenomenological analysis resulted in four themes: A sense of control, Balancing enjoyable options, Sharing with others and Learning made easier. The students point out that interactive technology promotes empowerment and independence, reduces stress and makes learning easier. They argue for a healthy balance of Internet use for it to be health promoting. According to the students, good relationships increase well-being; and interactive technology can offer a way to socialize, provide a tool for meeting and making new friends, help when not feeling well and give support when encouraging classmates. We argue, based on the findings of the present study and previous research, that students need a combination of freedom and meaningful relationships with adults who have an empowered child perspective, to fully take advantage of the empowering effects of interactive technology. We suggest, as implications for practice, that teachers, school leaders and health care professionals find ways to act as partners using an appreciative process, asking questions on what works well, to make interactive technology an enabling technology to increase health literacy, thus improving health and well-being in students., (© The Author 2015.

The use of closure devices after transbrachial arterial puncture is still controversial. Here we report on a case where the MYNXGRIP (AccessClosure Inc., Santa Clara, CA, USA) could be used successfully in a patient, who underwent percutaneous peripheral arterial intervention twice via transbrachial access.

Purpose: To investigate the effect of renal denervation (RDN) on blood pressure and renal function in refractory hypertension after renal artery recanalization and optimal medical therapy., Methods: Ten patients (6 women; mean age 70.0±5.1 years) with an office systolic blood pressure >160 mmHg despite taking ≥3 antihypertensive drugs and uni- or bilateral renal artery stenting were treated with RDN. Radiofrequency (RF) energy was delivered to the native segment of the artery keeping a 5-mm safe distance from the stented segments. Standardized office (OBP) and ambulatory (ABP) blood pressure measurements, medication, and renal assessment, including renal duplex ultrasound and renal function, were determined at baseline and on follow-up to 12 months., Results: OBP (systolic/diastolic) at baseline was 190.0±20.4 / 84.2±10.1 mmHg. It decreased to 171.1±28.7* / 82.2±8.7, 165.5±28.4(†) / 76.1±7.4, and 158.3±14.2(†) / 75.5±9.5(†) mmHg (*p<0.001; (†)p<0.01) at 3, 6, and 12 months after RDN, respectively. Average ABP (systolic/diastolic) after 6 and 12 months decreased by -7.6(‡) / -3.1 and -11.3(‡) / -5.1(‡) mmHg ((‡)p<0.05). There was no renal artery (re)stenosis, dissection, or aneurysm within 12 months. Creatinine, cystatin C, and glomerular filtration rate remained unchanged. Urine albumin excretion decreased in 4/10 patients. Renal resistive indices improved in native, but not in stented renal arteries within the follow-up period., Conclusion: This proof-of-concept study demonstrates that RF-based RDN can be safely and effectively delivered in patients with resistant hypertension and previous renal artery stenting.

Purpose: To evaluate the efficacy and safety of endovascular brachytherapy with liquid beta-emitting rhenium-188 (Re-188) in patients with long-segment in-stent stenosis in the femoropopliteal segment., Methods: From July 2009 to April 2011, 90 consecutive patients (59 men; mean age 68.3±10.3 years, range 43-86) with symptomatic in-stent stenosis/occlusion (24.6-cm mean lesion length) of the femoropopliteal segment underwent angioplasty and subsequent endovascular brachytherapy. The liquid beta-emitting Re-188 was applied to the target lesion within an angioplasty balloon using a dose of 13 Gy at a depth of 2 mm into the vessel wall. Clinical and angiographic follow-up data were collected up to 2 years. The main study endpoints were the 6- and 12-month primary patency rates defined as <50% in-stent stenosis as detected by duplex ultrasound. Clinical endpoints were the cumulative rates of death, amputation, and bypass surgery, as well as improvement in the Rutherford category and the ankle-brachial index. Results were correlated with patient and lesion characteristics., Results: Primary technical success was achieved in all patients, with 1 early stent thrombosis, but no other complications related to the irradiation. Eighty-eight patients reached the 6-month and 82 the 12-month examinations; the primary patency was 95.2% and 79.8%, respectively. In-stent stenosis occurred in 9 patients, while 10 patients had reocclusion of the treated segment. During follow-up, there were 2 late acute thrombotic occlusions, both after discontinuation of clopidogrel. The clinical status improved in 67.0% and 62.2% of the patients after 6 and 12 months, respectively. No patient, lesion, or procedure variables were predictive of restenosis after EVBT., Conclusion: EVBT with liquid beta-emitting Re-188 was safe and effective in preventing restenosis in long-segment femoropopliteal ISS.

Background: The Niobe Stereotaxis system consists of two 0.8 Tesla magnets and a navigation software allowing to move specially designed coronary wires., Aim: The aim of this observational multicenter study was to systematically evaluate the capability of the Stereotaxis Niobe Magnetic Navigation system to facilitate wire navigation during percutaneous coronary intervention (PCI), to determine the success rate of magnetically guided PCIs in a real-world setting, and to analyze procedure-related variables influencing the outcome data., Methods: One hundred and fifty seven patients underwent magnetically guided PCI in three German centers. Demographic variables of the patients, lesion quality determined by quantitative coronary angiography, success rate of the procedure as well as radiation time were analyzed. A subanalysis was performed for two periods (06/04-10/06 and 10/06-10/07) owing to a second generation of wires which was introduced at the beginning of the second period and procured-related learning curves of the operators., Results: Mean age of the patients was 65 +/- 0.4 years (82% male, 18% female). 25% of the patients were diabetics. The lesions were characterized by high complexity (11% AHA type A, 25% type B1, 38% type B2, 25% type C). Mean percent lesion stenosis was 83.7 +/- 11.9%. The total fluoroscopy time was 13.2 +/- 0.3 min and the fluoroscopy time to cross lesion was 90.4 +/- 62.2 s. The overall success rate of the magnetically guided approach was 89%. All failures occurred within the first period were. In these cases, 80% of the failures could be successfully treated after switching to the conventional wires. On the other hand, between 10/06 and 10/07 three conventional PCI failures could be successfully treated using the Stereotaxis system., Conclusions: Magnetically guided PCI represents a promising tool for the treatment of dedicated lesions. There is a marked difference in the success rates of the method between the two different time periods which were analyzed, reflecting advances in the wire development and learning curves of the respective operators. Randomized controlled trials are required to determine the method's overall value and to identify subgroups that may particularly benefit.

Objective: To elucidate the influence of drug-eluting stents (DESs) on interventional therapy of de novo unprotected left main stem (LMS) lesions in a hospital with on-site cardiac surgery., Methods and Results: A retrospective study of all patients with unprotected LMS angioplasty from 1999 to 2005 was conducted with regard to clinical and procedural data, and follow-up data. Fifty-four patients with unprotected LMS stenosis were treated inter-ventionally. Of these patients, 16 were treated with DESs. Seven patients presented with cardiogenic shock. During their hospital stay, four patients died (all treated with bare metal stents [BMSs], three initially presenting with cardiogenic shock). Follow-up data for 53 patients (98%) were obtained. Median follow-up time was 24 months (25th percentile, 12 months; 75th percentile, 35 months). Survival after nine months was 87% (81% from the BMS-treated group, and 100% from the DES-treated group). Control angiography had been performed in 36 patients (67%). Patients with unprotected LMS with an angiographic follow-up had a higher nine-month survival rate than patients without (36 of 36 patients [100%] versus 10 of 17 patients [59%], respectively; P<0.0001). Target lesion revascularization rate was 19% in both the BMS and the DES groups. Methods of revascularization did not vary significantly between the groups., Conclusions: In the present study of selected patients with LMS stenosis, the use of DESs showed a low mortality rate but did not have a clear effect on target lesion revascularization rate compared with BMSs. A close follow-up appears to be mandatory to achieve acceptable results.

Unlabelled: Tako-Tsubo cardiomyopathy (TTC) is described as left ventricular (LV) dysfunction with the phenomenon of "apical ballooning", rapidly resolving, without coronary artery stenoses., Methods: Fifteen patients with TTC and transthoracic echocardiography (TTE) at their admission, were reviewed (2001 to 2006). Follow-up (F/U) TTE was performed in varying intervals. To compare diameters of posterior wall (PW), interventricular septum (IVS), left atrium (LA), LV in end-diastole (LVED) and LV in end-systole (LVES) and valve insufficiencies, patients with comparable F/U are selected., Results: Fourteen patients were female (mean age 69.6 years). Angiography demonstrated LV systolic dysfunction with mean ejection fraction (EF) of 31.3%. In the acute-phase (day 0 to day 3), TTE showed a mean EF of 35.7%, not significantly different from EF obtained in angiography. Short-term F/U was performed in 9 patients after median time-interval of 20 days with an increase to a mean EF of 58.8%. F/U in 2006 has been performed in 10 patients (median time-interval 18.7 months) and showed normal EF. No significant difference in diameters of LA, LVED and LVES could be obtained comparing baseline and long-term data (p=0.493, p=0.790 and p=0.275). PW and IVS were significantly thicker at baseline compared to TTE > or = day 62 of F/U (p=0.003 and p=0.026). At baseline mitral valve insufficiency (MI) was mild in 50.0% and moderate in 12.5%, mild and moderate tricuspid valve insufficiency (TI) was recognized in 50% (25% respectively). MI and TI were regredient in F/U. In three patients an intraventricular systolic flow acceleration could be detected in the acute phase., Conclusions: Characteristics of TTC, besides transient LV apical ballooning are also a significant change in LV wall thickness and reversible valve insufficiencies.

A 44-year-old female presented with acute inferior myocardial infarction. Emergency coronary angiography showed an aneurysm of the proximal right coronary artery and an occlusion of the vessel downstream due to a huge organized thrombus. Mechanical fragmentation, glycoprotein IIb/IIIa antagonist, and intracoronary thrombolysis were all tested without success. Finally, the aneurysm was covered with a standard bare metal stent in order to trap the thrombus between the stent and the vessel wall and at least partially in the aneurysm. The strategy was successful, and after 1 week, the blood flow in the right coronary artery was normal; however, the aneurysm remained. After 6 months, there was significant in-stent restenosis of the proximal and mid segments of the right coronary artery but no evidence of the aneurysm. The restenosis was treated with two drug-eluting stents, leading to an excellent result after a further 6 months. The patient was free of symptoms and the left ventricular ejection fraction was within the normal range.

Introduction: Tako-tsubo cardiomyopathy represents an intermittent left ventricular dysfunction with a ballooning of the left ventricular apical myocardium without significant coronary artery disease. Precise epidemiological data are not yet available., Methods and Results: We retrospectively reviewed 16,989 cases with diagnostic angiographies in our catheter laboratory from January 2001 until December 2004 for intermittent left ventricular apical ballooning. Thirty-two (0.2%) patients were included (50% of all cases presented in 2004, 50% of all cases during the summer months). Twenty-nine (91%) were female, median age was 67.5 years. Fourteen patients (44%) were known to have chronic obstructive pulmonary disease or asthma. Thirteen patients (41%) reported an acute stressful event prior to onset of symptoms. Twenty-five (78%) of the patients presented with clinical signs of an acute coronary syndrome with positive troponin T in 20 (63%) patients. Median left ventricular ejection fraction was 42.5%. Follow-up data of 30 patients (94%) could be obtained; median follow-up time is 6 months. Two patients died during follow-up (malignancy; unknown cause). Echocardiography was performed in 26 (81%) patients; median ejection fraction was 70%., Conclusion: Tako-tsubo-like cardiomyopathy might be considered a differential diagnosis for acute coronary syndrome especially in elderly women. Chronic pulmonary diseases may be associated with a higher risk. The reason for the increasing number of cases during the last year is not clear; however, the tendency for early angiography in acute coronary syndrome may have contributed. The reason for the accumulation of cases during the summer months is also not yet understood.

Background: Apart from its well-known stimulation of erythropoiesis, erythropoietin (EPO) exhibits angiogenic and anti-apoptotic effects. These cellular protective effects have also been described in experimental acute myocardial infarction models. We investigated the effects of EPO in a porcine model of chronic progressive myocardial ischaemia., Methods: At weeks 2 and 6 after implantation of a circumflex ameroid constrictor, endocardial electromechanical NOGA system (Biosense Webster, Inc., California, USA) mapping of the left ventricle, coronary and ventricular angiography, as well as echocardiography were performed. Two weeks after ameroid placement, 13 pigs were randomized with 7 pigs receiving 10.000 U EPO and 6 pigs receiving placebo into the ischaemic region using a NOGA guided percutaneous transendocardial injection catheter, MYOSTAR. After 6 weeks, histology (Masson's Trichrome) was analyzed., Results: Endocardial electromechanical mapping showed an increase of mean unipolar voltage (UV) amplitude in the ischaemic myocardial segments in the EPO-treated animals (8.5 mV pre and 10.6 mV post treatment) and a significantly reduced ischaemic surface area compared to the control group (19% vs. 41%) suggesting a decline in ischaemic injury. Echocardiography revealed 2,2 hypokinetic segments of the lateral wall in the EPO group vs. 3,3 in the control groups. The mean ejection fraction was 64% in the EPO group and 55% in the placebo group. Quantitative histological analysis of the ischaemic regions revealed a reduction of myocardial fibrosis (8% vs. 28%) in the EPO group., Conclusion: Endocardial EPO injection may induce cardioprotective effects in hibernating myocardium and may attenuate the progression of ischaemic tissue damage.

Background: Dobutamine stress echocardiography (DSE) is an established method for the detection of viable myocardium, but evaluation of this method is subjective. Tissue velocity Imaging (TVI) allows quantitative analysis of regional myocardial wall motion by assessment of systolic myocardial velocities. The aim of this study was to evaluate the diagnostic value of DSE and TVI for detection of viable myocardium., Methods: In 56 patients (58+/-12 years) with previous myocardial infarction (130+/-42 days, mean ejection fraction 42+/-15%) low-dose DSE was combined with analysis of peak systolic myocardial velocities (Vpeak) by TVI for assessment of myocardial viability. As reference served a follow-up echocardiography after successful revascularization (mean 91+/-3 days)., Results: Of a total of 896 segments 200 showed abnormal wall motion (31 mildly hypokinetic, 50 severely hypokinetic, 115 akinetic, 4 dyskinetic). In 125 of these 200 segments regional improvement of regional wall motion was observed (62.5% viable). An increase of Vpeak>1 cm/s during dobutamine stimulation allowed the identification of viable myocardium with a sensitivity of 82% and a specificity 82% (DSE: 77% and 80%). By receiver operating characteristic (ROC) curve analysis, a cut-off value of 1.0 cm/s was the best parameter to differ viable from nonviable myocardium (area under the curve 0.85; p<0.01; 95% CI 0.79 to 0.90). Improvement of global ejection fraction after revascularization (47+/-13%, p=0.11) corresponded with three TVI viable segments with a sensitivity of 92% and a specificity of 89% (p=0.012)., Conclusions: TVI allows the identification of viable myocardium during dobutamine stimulation and enables a quantitative interpretation of DSE.

Introduction: In interventional cardiology an increasing demand to treat complex coronary lesions (i.e. distal lesions, tortuous vessels, chronic occlusions) has developed within the last years. New devices to fulfill this demand are therefore needed., Methods and Results: The magnetic navigation system (Niobe System; Stereotaxis Inc.) represents a novel system which allows 3-dimensional control of the guide wire tip using magnetic fields. Two computer controlled permanent magnets on each side of the patient create a uniform magnetic field which can freely be directed. A small magnet at the guide wire tip will align according to the vector of the magnetic field. Advancing and retracting of the wire is to be done manually. The remaining steps of angioplasty (i.e. balloon angioplasty and stent implantation) are performed conventionally, after magnetically guided crossing of the target lesion.The study was performed to proof the feasibility of the technique in the treatment of coronary lesions. Seventy seven patients with 82 coronary lesions underwent magnetic guided coronary interventions. Sixty three lesions (77%) could be crossed successfully using magnetic guidance, 13 more by switching to conventional guide wires. Successful angioplasty (with or without stent implantation) was achieved in 74 lesions (90%). Mean fluoroscopy time was 13,9+/-8 min., Conclusions: The use of magnetic guidance in coronary interventions is a promising tool to treat complex coronary lesions. With more experience and improved devices (i.e. coated wires, steerable microcatheters) the safety and efficacy of the procedures should be improved.

Background: Catheters are typically stiff and incorporate a pull-wire mechanism to allow tip deflection. While standing at the patient's side, the operator manually navigates the catheter in the heart using fluoroscopic guidance., Methods and Results: A total of 42 patients (32 female; mean age, 55+/-15 years) underwent ablation of common-type (slow/fast) or uncommon-type (slow/slow) atrioventricular nodal reentrant tachycardia (AVNRT) with the use of the magnetic navigation system Niobe (Stereotaxis, Inc). It consists of 2 computer-controlled permanent magnets located on opposite sides of the patient, which create a steerable external magnetic field (0.08 T). A small magnet embedded in the catheter tip causes the catheter to align and to be steered by the external magnetic field. A motor drive advances or retracts the catheter, enabling complete remote navigation. Radiofrequency current was applied with the use of a remote-controlled 4-mm, solid-tip, magnetic navigation-enabled catheter (55 degrees C, maximum 40 W, 60 seconds) in all patients. The investigators, who were situated in the control room, performed the ablation using a mean of 7.2+/-4.7 radiofrequency current applications (mean fluoroscopy time, 8.9+/-6.2 minutes; procedure duration, 145+/-43 minutes). Slow pathway ablation was achieved in 15 patients, whereas slow pathway modulation was the end point in the remaining patients. There were no complications., Conclusions: The Niobe magnetic navigation system is a new platform technology allowing remote-controlled navigation of an ablation catheter. In conjunction with a motor drive unit, this system was used successfully to perform completely remote-controlled mapping and ablation in patients with AVNRT.

Aims: This is the first report of a young female with typical AVNRT in the presence of a persistent left superior caval vein that underwent catheter ablation using the novel magnetic navigation system (MNS) Niobe (Stereotaxis Inc.)., Methods: The MNS consists of two outer permanent magnets (about 0.1 T) that align a third small magnet integrated in the tip of a mapping and ablation catheter along its magnetic field lines. By changing the orientation of the outer magnets, the orientation of the magnetic field lines also change, thereby allowing navigation of the ablation catheter. In combination with an automated advancer system, this novel technique allows for the first time complete remote catheter ablation., Results: Successful slow pathway modulation was performed using a total of seven radiofrequency current applications via the magnetic ablation catheter. No complication occurred., Conclusions: The novel magnetic navigation system proved to be a safe and feasible tool for remote catheter ablation of common type AVNRT in the presence of a persistent left superior caval vein.

Objective: The purpose of this study was to validate electromechanical viability parameters with combined myocardial perfusion and metabolic imaging and echocardiography., Background: The NOGA System is a catheter-based, non-fluoroscopic, three-dimensional endocardial mapping system. This unique technique allows accurate simultaneous assessment of both local electrical activity and regional contractility., Methods: The results of NOGA, myocardial single-photon emission computed tomography (SPECT), positron emission tomography, and echocardiography in 51 patients with coronary artery disease and a pathologic SPECT study were transcribed in a nine-segment bull's-eye projection and compared. The local shortening of normally contracting segments, as shown by echocardiography, was 9.2 +/- 5.1%, which decreased to 6.6 +/- 5.0% and 4.1 +/- 5.2% in hypokinetic and akinetic segments. The highest unipolar voltage (11.2 +/- 5.0 mV) and local shortening (8.2 +/- 5.0%) characterized normally perfused segments. Fixed perfusion defects with normal or limited 18-fluoro-2-deoxy-D-glucose uptake indicating viability had a significantly higher unipolar voltage than did scar tissue (7.25 +/- 2.7 vs. 5.0 +/- 3.1 mV, p = 0.029)., Conclusion: Electromechanical parameters sufficiently defined the viability state of the myocardium and showed good concordance with the findings by nuclear perfusion and metabolism imaging and echocardiography. The NOGA technique provides all the relevant information immediately after coronary angiography and enables the physician to proceed with therapy in the same setting.

Percutaneous myocardial laser therapy is a new strategy for myocardial revascularization in patients with end-stage coronary artery disease. The laser impulse which is applied via a catheter creates small channels into ischemic myocardium from the endocardial surface. Different mechanisms such as angiogenesis, improved blood flow via open channels or neural stunning are discussed as the underlying mechanism. Precise identification and maneuvering of the laser catheter to the target zone is of crucial importance. By using a novel catheter-based, non-fluoroscopic, three-dimensional endocardial mapping system (NOGA, Biosense-Webster Co.) accurate simultaneous assessment of both local electrical activity and regional contractility can be obtained. The analysis of uni- or bipolar voltage and linear local shortening allows an exact differentiation of scar tissue from viable myocardium. In addition, due to the high spatial resolution of the NOGA system the application of laser channels at the same site can be avoided, which increases the safety of the procedure. To assess the efficacy of the NOGA based myocardial lasing procedure a multicenter randomized study (Euro-direct) is presently underway.
