Developing a low back pain guideline implementation programme in collaboration with physiotherapists and chiropractors using the Behaviour Change Wheel: a theory-driven design study

BACKGROUND

Low back pain is still the leading cause of disability and societal burden, with 619 million prevalent cases worldwide in 2020. Most countries produce clinical guidelines to support healthcare professionals in evidence-based care regarding low back pain. However, several studies have identified relatively poor uptake of guidelines. Tailored strategies to facilitate the implementation of guidelines have been argued to increase uptake. This study aimed to develop a contextually tailored implementation programme to enhance evidence-based low back pain care among Danish physiotherapists and chiropractors in primary care.

METHODS

A theory-driven implementation programme development study was conducted using the Behaviour Change Wheel, with high healthcare professional involvement. Data collection included four workshops with seven physiotherapists and six chiropractors from primary care clinics. The development process consisted of [1] establishing a theoretical frame, [2] involving participants, [3] understanding the behaviour, [4] designing the implementation programme, and [5] final implementation programme.

RESULTS

The target behaviours selected (guideline recommendations) for the implementation programme were (i) screening of psychosocial risk factors and (ii) offering patient education. The barriers and facilitators for the selected behaviours were described and linked to intervention functions and behavioural techniques. Finally, the implementation programme comprised five strategies: webinars, e-learning videos, communication exercises, peer learning, and group dialogue meetings. In addition, the programme consisted of implementation support: champions, a physical material folder, a weekly email reminder, a specially designed website and a visit from an implementation consultant. An essential element of the overall programme was that it was designed as a step-by-step implementation process consisting of 16 h of education and training distributed over 16 weeks.

CONCLUSIONS

A programme for implementing low back pain guideline recommendations was developed based on behaviour change theory and four co-design workshops involving healthcare professionals to overcome the contextually identified barriers. A theory-driven approach involving healthcare professionals was useful in identifying relevant target behaviours and tailoring the programme to consider contextual barriers and facilitators for implementation. The effectiveness of the final implementation programme will be evaluated in the project's next phase.

A Systematic Review of Telehealth-Based Pediatric Cancer Rehabilitation Interventions on Disability

Background: Telehealth is an emerging method which may overcome barriers to rehabilitation access for pediatric cancer survivors (aged ≤19 years). This systematic review aimed to examine telehealth-based rehabilitation interventions aimed at preventing, maintaining, or improving disability in pediatric cancer survivors. Methods: We performed systematic searches in Ovid MEDLINE, Ovid EMBASE, Cochrane Library, SCOPUS, Web of Science, and CINAHL Plus between 1994 and 2022. Eligible studies included telehealth-based interventions assessing disability outcomes in pediatric cancers. Results: Database searches identified 4,040 records. Nine unique interventions met the eligibility criteria. Telehealth delivery methods included telephone (n = 6), email (n = 3), mobile health applications (n = 3), social media (n = 3), videoconferencing (n = 2), text messaging (n = 2), active video gaming (n = 2), and websites (n = 2). Interventions focused on physical activity (n = 8) or self-management (n = 1). Outcomes assessing disability varied (n = 6). Three studies reported statistically and clinically significant results. Narrative synthesis of findings was constructed based on the Picker's principles for patient-centered care: (1) values, preferences, and needs; (2) involve family and friends; (3) coordination of care; (4) provide social support; (5) holistic well-being; and (6) information and communication. Conclusions: Telehealth-based rehabilitation interventions for pediatric cancer survivors is an emerging research area with potential to improve disability outcomes. Adequately powered trials with consistency in disability outcome measures are warranted. Additional research is needed to determine the effectiveness and best practices for telehealth-based pediatric cancer rehabilitation.

Peri-operative tobacco cessation interventions: a systematic review and meta-analysis

Tobacco smoking is associated with a substantially increased risk of postoperative complications. The peri-operative period offers a unique opportunity to support patients to stop tobacco smoking, avoid complications and improve long-term health. This systematic review provides an up-to-date summary of the evidence for tobacco cessation interventions in surgical patients. We conducted a systematic search of randomised controlled trials of tobacco cessation interventions in the peri-operative period. Quantitative synthesis of the abstinence outcomes data was by random-effects meta-analysis. The primary outcome of the meta-analysis was abstinence at the time of surgery, and the secondary outcome was abstinence at 12 months. Thirty-eight studies are included in the review (7310 randomised participants) and 26 studies are included in the meta-analysis (5969 randomised participants). Studies were pooled for subgroup analysis in two ways: by the timing of intervention delivery within the peri-operative period and by the intensity of the intervention protocol. We judged the quality of evidence as moderate, reflecting the degree of heterogeneity and the high risk of bias. Overall, peri-operative tobacco cessation interventions increased successful abstinence both at the time of surgery, risk ratio (95%CI) 1.48 (1.20-1.83), number needed to treat 7; and 12 months after surgery, risk ratio (95%CI) 1.62 (1.29-2.03), number needed to treat 9. More work is needed to inform the design and optimal delivery of interventions that are acceptable to patients and that can be incorporated into contemporary elective and urgent surgical pathways. Future trials should use standardised outcome measures.

Implementing smoking cessation in routine primary care-a qualitative study

Background

The use of digital tools has been proposed as a solution to some of the challenges of providing preventative services in primary care. Although there is a general acceptance among patients to use digital self-help tools to quit smoking, and healthcare organizations are increasingly urged to incorporate these tools in clinical practice, it is unclear how and for whom these innovations can be incorporated into clinical practice.

Objectives

To explore health care professionals' perceptions about smoking cessation practice in routine primary care and the use of digital tools in this work.

Methods

A qualitative study with nine in-depth telephone interviews with health care professionals working in primary care in Sweden. Convenience sampling and snowball technique was used as recruitment strategy. Informants included registered, district and auxiliary nurses as well as behavioral therapists. All informants were female, between 43 and 57 years old and experience of working with smoking cessation in primary care and possibility to recommend digital interventions to smokers.

Results

Informants described smoking cessation practice in primary care as (i) identifying smoking patients, (ii) pursuing standardized routines for smoking cessation practice and (iii) keeping smoking cessation practice on the agenda. Digital tools were described by informants to be used in different ways: (i) replicating practice, (ii) complementing practice and (iii) enabling access to health care practitioners. Finally, the analysis showed that patients' expectations and behaviors contributed to how and when smoking cessation practice was conducted, including the use of digital tools.

Conclusions

Implementing smoking cessation practice in primary care in Sweden encompass continuous work of reaching smoking patients, building buy-in among peers and keeping tobacco on the practice agenda. Digital interventions are used to replicate, complement and enabling access to care. The findings suggest that poor continuity of staff and negative attitudes towards preventative work may challenge smoking cessation practice. However, societal changes in the awareness of the health risks of tobacco use including shifting social norms regarding the acceptance of smoking may contribute to a normalization of speaking about smoking in primary care practice. Increased knowledge is needed on how, and for whom digital tools can be incorporated in clinical practice.

Mixed Methods, Implementation Science Evaluation of a Community Health Worker Strategy for HIV Service Engagement in Uganda

BACKGROUND

A trial found that a community health worker (CHW) strategy using "Health Scouts" improved HIV care uptake and ART coverage. To better understand outcomes and areas for improvement, we conducted an implementation science evaluation.

METHODS

Using the RE-AIM framework, quantitative methods included analyses of a community-wide survey (n = 1903), CHW log books, and phone application data. Qualitative methods included in-depth interviews (n = 72) with CHWs, clients, staff, and community leaders.

RESULTS

Thirteen Health Scouts logged 11,221 counseling sessions; 2532 unique clients were counseled. 95.7% (1789 of 1891) of residents reported awareness of the Health Scouts. Overall, reach (self-reported receipt of counseling) was 30.7% (580 of 1891). Unreached residents were more likely to be male and HIV seronegative ( P < 0.05). Qualitative themes included the following: (1) reach was promoted by perceived usefulness but deterred by busy client lifestyles and stigma, (2) effectiveness was enabled through good acceptability and consistency with the conceptual framework, (3) adoption was facilitated by positive impacts on HIV service engagement, and (4) implementation fidelity was initially promoted by the CHW phone application but deterred by mobility. Maintenance showed consistent counseling sessions over time. The findings suggested the strategy was fundamentally sound but had suboptimal reach. Future iterations could consider adaptations to improve reach to priority populations, testing the need for mobile health support, and additional community sensitization to reduce stigma.

CONCLUSIONS

A CHW strategy to promote HIV services was implemented with moderate success in an HIV hyperendemic setting and should be considered for adoption and scale-up in other communities as part of comprehensive HIV epidemic control efforts.

How health care professionals handle limited resources in primary care - an interview study

INTRODUCTION

Health care systems around the world are struggling with limited resources, in relation to the prevailing health care need. An accessible primary care is an important part of the solution for how to provide affordable care for the population and reduce pressure on the overall health care system such as unnecessary hospital stays and associated costs. As primary care constitutes an important first line of healthcare, the task of prioritising and deciding what to do and for whom lies in practice, primarily with the primary care professionals. Thus, the decisions and behaviour of primary care professionals have a central role in achieving good and equal health in the population. The aim of this study is to explore how primary health care professionals handle situations with limited resources and enhance our knowledge of priorities in practice.  METHODS: Semi-structured interviews with 14 health care professionals (7 nurses, 7 physicians) working in Swedish primary care were interviewed. Data were analysed inductively with content analysis.

FINDINGS

Three main categories were found: Influx of patients; Structural conditions; and Actions. Each category illustrates an important aspect for what primary care professionals do to achieve good and equal care. The influx of patients concerned what the professionals handled in terms of patients' healthcare needs and patient behaviour. Structural conditions consisted of policies and goals set for primary care, competence availability, technical systems, and organisational culture. To handle situations due to limited resources, professionals performed different actions: matching health care needs with professionals' competency, defining care needs to suit booking systems appointments, giving care at the inappropriate health care level, rearranging workhours, and passing on the decision making.

CONCLUSION

Priorities in primary care are not, "one fits all" solution. Our study shows that priorities in primary care comprise of ongoing daily processes that are adapted to the situation, context of patient influx, and structural conditions. Healthcare professional's actions for how influx of patients' is handled in relation to limited resources, are created, and shaped within this context which also sets the boundaries for their actions.

Relationship Between Educational Level and Attitudes Towards Alcohol Conversations in Healthcare: A Cross-Sectional Survey Conducted in Four European Countries

Objectives: To examine the association between educational level and attitudes towards alcohol conversations in healthcare using population-based surveys of adults in England, the Netherlands, Norway, and Sweden; and to compare attitudes towards alcohol conversations in healthcare between these four countries. Methods: Cross-sectional surveys were conducted amongst adults in the general population in England (n = 3,499), the Netherlands (n = 2,173), Norway (n = 1,208), and Sweden (n = 3,000). Logistic regression analysis was used to examine associations between attitudes towards alcohol conversations in healthcare and educational level, key demographic variables, alcohol consumption, and country of residence. Results: In all four countries, low educational level (p < 0.001) and male gender (p < 0.001) were associated with holding negative attitudes towards discussing alcohol in healthcare. Risky drinkers had more negative attitudes than low risky drinkers towards discussing alcohol in healthcare (p < 0.001) in all countries except England (p = 0.48), and also reported low levels of perceived honesty and confidence in healthcare (p < 0.001). Conclusion: These findings highlight the importance of considering patients' socio-economic status when developing and implementing alcohol prevention interventions in healthcare.

The importance of trusting conditions for organizations' readiness to implement mHealth to support healthy lifestyle behaviors: An interview study within Swedish child and school healthcare

Objective

To explore perceptions among nurses, managers, and policymakers regarding organizational readiness to implement mHealth for the promotion of healthy lifestyle behaviors in child and school healthcare.

Methods

Individual semi-structured interviews with nurses (n = 10), managers (n = 10), and policymakers (n = 8) within child and school healthcare in Sweden. Inductive content analysis was used for data analysis.

Results

Data showed that various trust-building aspects in health care organizations may contribute to readiness to implement mHealth. Several aspects were perceived to contribute trusting conditions: (a) how health-related data could be stored and managed; (b) how mHealth aligned with current organizational ways of working; (c) how implementation of mHealth was governed; and (d) camaraderie within a healthcare team to facilitate use of mHealth in practice. Poor capability to manage health-related data, as well as lack of governance of mHealth implementation were described as dealbreakers for readiness to implement mHealth in healthcare organizations.

Conclusions

Healthcare professionals and policymakers perceived that trusting conditions for mHealth implementation within organizations were central for readiness. Specifically, governance of mHealth implementation and the ability to manage health-data produced by mHealth were perceived critical for readiness.

Study protocol for an effectiveness-implementation hybrid trial to evaluate a health promotion intervention in parents and their 5-year-old child: Saga Stories in health talks in Swedish child healthcare

BACKGROUND

Unhealthy lifestyle behaviours such as a poor diet, inadequate physical activity, and excessive screen time have been shown to be established in childhood and track into adulthood, demonstrating the need for health promotion interventions in the pre-school years. The overall aim of this project is to: (i) evaluate the effectiveness of `Saga Stories in health talks´ within child healthcare (CHC) on parental self-efficacy to promote healthy diet, physical activity, and screen time behaviours in their child; children's intake of key dietary indicators and screen time and (ii) evaluate and explore the implementation of `Saga Stories in health talks´ with regards to acceptability, appropriateness, feasibility, fidelity, adoption, sustainability, satisfaction, and usage.

METHODS

A hybrid type I effectiveness-implementation trial will be conducted. A cluster randomized controlled trial will be used to assess the effectiveness of `Saga Stories in health talks´ in 42 CHC centers across six regions in Sweden. `Saga Stories in health talks´ consists of material for CHC nurses to use to facilitate the health talk with both the child and parent(s) and is complemented with take-home material. Parent and child dyads are recruited (n = 450) from participating CHC centers when they attend their 5-year routine visit. The intervention group receives the health talk using Saga Stories and take-home material, whereas the control group receives the standard health talk. The primary outcome is parental self-efficacy to promote healthy diet, physical activity, and screen time behaviours in their child and secondary outcomes include children's intake of key dietary indicators and screen time. All outcomes are assessed at baseline and 2-months post-intervention. The implementation outcomes that will be assessed are: acceptability, appropriateness, feasibility, satisfaction, usage, fidelity, adoption, and sustainability (assessed quantitatively and qualitatively).

DISCUSSION

The Swedish National Board of Health and Welfare have identified the need of more material, education, and working methods for promoting healthy lifestyle behaviours in CHC. Following this trial `Saga Stories in health talks´ has great potential to be implemented in CHC across Sweden to aid nurses to promote and support healthy lifestyle behaviours in pre-school children and their families.

Exploring the Black Box of an mHealth Intervention (LIFE4YOUth): A Qualitative Process and Outcome Evaluation of End-User Engagement

The effectiveness of mHealth interventions rely on whether the content successfully activate mechanisms necessary for behavior change. These mechanisms may be affected by end-users' experience of the intervention content. The aim of this study was to explore how the content of a novel mHealth intervention (LIFE4YOUth) was understood, interpreted, and applied by high school students, and the consequences of engaging with the content. Qualitative content analysis was used inductively and deductively to analyze interview data (n = 16) based on think-aloud techniques with Swedish high school students aged 16-19 years. Theoretical constructs from social cognitive theory framed the deductive analysis. The analysis resulted in four categories which describe central activities of intervention engagement among end-users: defining, considering, centralizing, and personalizing. End-users engaged in these activities to different degrees as illustrated by four typologies: Literal, Vague, Rigid, and Creative engagement. Most informants knew about the risks and benefits of health behaviors, but engagement with intervention content generally increased informants' awareness. In conclusion, this study provides in-depth knowledge on the cognitive process when engaging with mHealth content and suggests that deliberate and flexible engagement most likely deepens end-users' understanding of why and how health behavior change can be managed.

SARS-CoV-2 is associated withabnormal biomarkers of oxidative stress,and endothelial function linked with cardiovascular dysfunction four months after the infection

Introduction

COVID-19 infection has been associated with increase arterial stiffness, endothelialdysfunction, and impairment in coronary and cardiac performance. Inflammation and oxidative stress have beensuggested as possible pathophysiological mechanisms leading to vascular and endothelial deregulation afterCOVID-19 infection.

Purpose

The objective of our study is to evaluate premature alterations in arterial stiffness, endothelial,coronary, and myocardial function markers four months after SARS-CoV-2 infection.

Methods

In a case-control prospective study, we included 70 patients 4 months after COVID-19 infection, 70 age- and sex-matched untreated hypertensive patients (positive control) and 70 healthy individuals. We measured (i) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced endothelial glycocalyx thickness), (ii) flow-mediated dilatation (FMD), (iii) coronary flow reserve (CFR) by Doppler echocardiography, (iv) pulse wave velocity (PWV) and central systolic blood pressure (cSBP), (v) global left and right ventricular longitudinal strain (GLS), (vi) malondialdehyde (MDA), an oxidative stress marker, thrombomodulin and von Willebrand factor as endothelial biomarkers.

Results

COVID-19 patients had similar CFR and FMD with hypertensives (2.48±0.41 vs 2.58±0.88, p=0.562, 5.86±2.82% vs 5.80±2.07%, p=0.872 respectively) but lower values than controls (3.42±0.65, p=0.0135, 9.06±2.11%, p=0.002 respectively). Compared to controls, both COVID-19 and hypertensives had greater PBR5–25 (2.07±0.15μm and 2.07±0.26μm p=0.8 vs 1.89±0.17μm, p=0.001), higher PWV, (12.09±2.50 vs 11.92±2.94, p=0.7 vs 10.04±1.80m/sec, p=0.036) increased cSBP (128.43±17.39 vs 135.17±16.83 vs 117.89±18.85) and impaired LV and RV GLS (−19.50±2.56% vs −19.23±2.67%, p=0.864 vs −21.98±1.51%, p=0.020 and −16.99±3.17% vs −18.63±3.20%, p=0.002 vs −20.51±2.28%, p<0.001). MDA and thrombomodulin were higher in COVID-19 patients than both hypertensives and controls (10.67±2.75 vs 1.76±0.30, p=0.003 vs 1.01±0.50nmole/L, p=0.001 and 3716.63±188.36 vs 3114.46±179.18, p=0.017 vs 2590.02±156.51pg/ml, p<0.001). COVID-19 patients displayed similar vWF values with hypertensives but higher compared with healthy controls (4018.03±474.31 vs 3756.65±293.28 vs 2079.33±855.10 ng/ml, p=0.718 and p=0.016 respectively).

Conclusions

SARS-CoV-2 infection is associated with oxidative stress, endothelial and vascular dysfunction, which are linked to impaired longitudinal myocardial deformation 4 months after COVID-19 infection.

Impaired endothelial glycocalyx, vascular dysfunction and myocardial deformation four months after COVID-19 infection are partially improved at twelve months

Introduction

COVID-19 patients present impaired subclinical markers of cardiovascular and endothelial function. Subclinical myocardial and vascular dysfunction during COVID-19 disease have been associated with worse outcomes and higher mortality risk.

Purpose

We investigated the effect of COVID-19 infection on markers of endothelial, vascular and myocardial function at four and twelve months after the infection

Methods

We recruited 70 patients who were examined in a dedicated post-COVID-19 outpatient clinic during a scheduled follow-up visit at four and twelve months after a confirmed COVID-19 infection and 70 healthy individuals with similar clinical characteristics. At four and twelve months we measured (i) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced endothelial glycocalyx thickness), (ii) flow-mediated dilatation (FMD), (iii) coronary flow reserve (CFR) by Doppler echocardiography, (iv) pulse wave velocity (PWV) and central systolic blood pressure (cSBP), (v) global left and right ventricular longitudinal strain (GLS), (vi) myocardial global work index (GWI) global constructive work (GCW), global wasted work (GWW) and the myocardial global work efficiency (GWE) and v) malondialdehyde (MDA), an oxidative stress marker.

Results

At four months, COVID-19 patients displayed higher values of PBR5–25 compared to control group (p<0.001) which increased at twelve months (p<0.001). FMD, PWV and cSBP values were similar between 4 and 12 months (p>0.05 for all the comparisons) and higher than those in controls (p<0.001, p=0.057, p=0.003 respectively). At four months, COVID-19 patients presented impaired CFR and LVGLS values which were improved at twelve months (p=0.002, p=0.069 respectively), though remained impaired compared to controls (p=0.003 for all the comparisons). At four months, COVID-19 patients had impaired RVGLS values which were significantly improved at twelve months (p=0.001,) and showed no statistically significant difference compared to controls (p>0.05). COVID-19 patients at four months display higher myocardial wasted work and decreased myocardial efficiency compared to controls (p=0.01, p=0.006 respectively). There was a modest improvement in GWW and GWE at twelve months,(p=0.043, p=0.001, respectively); however, these markers remained impaired compared to controls (p>0.05). At four months, MDA was higher in COVID-19 patients compared to control group and significantly decreased at twelve months (p<0.001); however, these values remain higher than in controls (p=0.002) (Table 1).

Conclusions

SARS-CoV-2 causes endothelial and cardiovascular dysfunction which are partially restored at twelve months after the infection.

POS0832 MORTALITY TRENDS IN ANCA-ASSOCIATED VASCULITIDES (AAVs): DATA FROM A CONTEMPORARY, MULTICENTER ANCA REGISTRY

Background

AAVs are a group of rheumatic diseases with excess morbidity and mortality (~3-fold higher compared to the general population). Long-term studies looking at mortality trends in contemporary patient cohorts are limited.

Objectives

To investigate the overall long-term survival and all-cause mortality in a contemporary AAV patient cohort.

Methods

Multicenter cohort study of patients registered and prospectively followed in the Greek ANCA Registry.

Results

Data for 165 patients (989.38 patient-years of follow up) with a diagnosis of AAV (GPA n=95, 58%, MPA n=54, 33%, EGPA n=16, 9%) were analyzed (January 1, 1998 - January 10, 2022). 53% of patients were female, with a mean age of 65 (±16.4) years; the majority (97%) had generalized disease and were ANCA positive (76%). The mean follow-up since diagnosis was 5.9 (±5.1) years. At the end of follow-up, the overall mortality rate was 20% (33/165), whereas the cumulative mortality rates at 5 and 10 years were 24% and 26% respectively. Overall cumulative survival at 5 years was worse in patients with MPA (57%) compared to GPA (81%) and EGPA (92%), (p<0.001). There was no difference in long-term survival among those treated with different induction regimens including cyclophosphamide (CYC, n of deaths=24/83, 28.9%), rituximab (RTX, n=4/40, 10%) or the CYC+RTX combination (n=3/16, 18.7%). Furthermore, there was no difference in survival between relapsing (≥1 relapses) and non-relapsing (n=76) patients (Figure 1). Cumulative survival was worse in patients who initially presented with lung (66% vs. 90% at 5 years, p=0.007), kidney (56% vs. 96% at 5 years, p<0.001) and simultaneous lung and kidney (39% vs. 93% at 5 years, p<0.001) involvement. Among the 33 registered deaths, the most frequent causes were infections (52%), followed by cardiovascular events (24%), disease flares (14%) and malignancies (10%).

Figure 1.

Conclusion

In a contemporary multi-center AAV cohort, the cumulative mortality rates at 5 and 10 years were 24% and 26% respectively. Overall survival was worse in patients with MPA as well as those with combined lung and kidney involvement at baseline while there were no survival differences according to the initial induction regimen. Infection was the most common cause of death. These findings emphasize the unmet needs for better, less toxic therapies.

Endoscopic surveillance after bariatric surgery: Results from a large, single-institution cohort

Objective

Sleeve gastrectomy (SG) and Roux-en-Y-gastric bypass (RYGB) are associated with long- term abnormalities, including erosive esophagitis (EE), hiatal hernia (HH), gastritis, Barrett`s esophagus and ulcers. The aim of this study is to assess the prevalence of abnormal endoscopic and histologic findings after SG and RYGB in a large cohort.

Methods

This is a retrospective analysis of 720 consecutive patients who underwent esophagogastroduodenoscopy (EGD) after primary SG or RYGB. Patients were invited for a control EGD after two years of follow-up. EGD was also performed in order to evaluate postoperative symptoms, such as nausea, vomiting or reflux. If revisional surgery was planned, an EGD was included in the prerevisional work up.

Results

304 post-SG patients (64.1% female) and 416 post-RYGB patients (85% female) were included. The mean age at the time of operation was 43.9 years (95% confidence intervals (CI) 42.5–43.3 years) for the post-SG group and 40.5 years (95% CI 39.4–41.6 years) for the post-RYGB group (p&lt;0.001). The mean preoperative body mass index (BMI) was 44.2 kg/m2 (95%CI 43.4–44.9) and 41.1 kg/m2 (95%CI 40.7–41.5) for the post-SG and the post-RYGB group respectively (p&lt;0.001). EE, gastritis and HH were more prevalent after SG than RYGB (38.8% vs 8.9%, 62.5% vs 27.6% and 28% vs 2.6% respectively, p&lt;0.001). RYGB was associated with more postoperative ulcers than SG (14.4% vs 0.7%, p&lt;0.001). The incidence of anastomotic strictures requiring anastomotic dilatation after RYGB was 4.6%. No significant difference was found in the prevalence of Barrett`s esophagus (4.3% post SG vs. 4.1 post RYGB, p=1.000) and Helicobacter pylori (3.3% post SG vs. 1.2% post RYGB, p=0.065) between the two groups.

Conclusion

SG is associated with higher rates of EE, gastritis and HH, while the prevalence of ulcers is higher post RYGB. There is a low risk of anastomotic stricture post RYGB. The incidence of Barrett`s oesophagus is low after both procedures. Routine use of EGD after bariatric surgery should be evaluated.

AB0633 Health-Related Quality of Life in ANCA Vasculitides and Rheumatoid Arthritis patients: a cross-sectional comparative study

Background

ANCA associated vasculitides (AAVs) are rare, serious forms of vasculitides. There are limited data regarding the quality of life in patients with AAVs compared to other chronic inflammatory diseases.

Objectives

The purpose of this study was to compare the quality of life between patients with AAV and those with a chronic inflammatory arthritis such as rheumatoid arthritis (RA).

Methods

Multicenter, cross-sectional study of AAV and RA patients followed in three tertiary referral centers. Data from 1007 healthy controls served as historic controls.1 HRQoL was assessed with the Short Form 36 Health Survey (SF-36) which includes physical and mental component summary scores (PCS and MCS). Disease activity were assessed with the Birmingham Vasculitis Activity Score version 3 (BVAS 3, for AAVs) and the DAS28-ESR (for RA) respectively and organ damage/function with the Vasculitis Damage Index (VDI for AAVs) score and Health Assessment Questionnaire (HAQ for RA) scores, respectively.

Results

66 patients with AAVs (GPA 62%, MPA 29% and EGPA 9%, females 56%, mean age 63.4 years, generalized disease 74%, mean disease duration 6.2 years, remission 73%) and 71 with RA (females 56%, mean age 63.3 years, remission 72%) were included. Both AAV and RA patients had significantly lower PCS and MCS scores compared to healthy controls (p < 0.05) while RA patients had lower PCS and MCS scores compared to AAV patients (p < 0.05). According to disease activity status, there was no difference in the SF-36 scores between those with active (BVAS > 1) and inactive (BVAS < 1) AAV, except for the energy-fatigue component (55.0 ± 21.8 vs. 67.2 ± 20.7, p= 0.038) whereas patients with active RA (DAS28-ESR > 3.2) had lower scores for all SF36 components compared to those with low disease activity (DAS28-ESR < 3.2). Additionally, active RA patients had lower both PCS and MCS scores compared to active AAV patients (p < 0.05). AAV patients with increased damage scores (VDI > 3) had lower PCS score compared to those with less organ damage (VDI < 3), (33.9 ± 10.1 vs. 49.1 ± 10.2, p < 0.001) while RA patients with increased damage/poor functionality (HAQ ≥ 0.75) had lower both PCS and MCS scores compared to those with less damage (HAQ ≤ 0.63), (35.0 ± 7.2 vs. 48.4 ± 8.6, p < 0.001) and (40.5 ± 8.6 vs. 48.2 ± 7.6, p < 0.001 respectively). Compared to patients with AAV, RA patients with increased damage had lower score for the pain component compared to AAV patients (37.7 ± 28.6 vs. 61.2 ± 29.5, p= 0.024).

Conclusion

In general, patients with AAV and RA, demonstrate impaired quality of life compared to healthy controls. In the AAV group, quality of life correlated more with organ damage and less with disease activity whereas in RA patients, quality of life correlated both with disease activity and damage. These data emphasize the need for more efficacious therapies for AAV patients that could prevent chronic organ damage and improve quality of life.

Treatment outcomes of bladder stones in children with intact bladders in developing countries: A systematic review of >1000 cases on behalf of the European Association of Urology Bladder Stones Guideline panel

INTRODUCTION

Bladder stones (BS) are still endemic in children in developing nations and account for a high volume of paediatric urology workload in these areas. The aim of this systematic review is to comparatively assess the benefits and risks of minimally invasive and open surgical interventions for the treatment of bladder stones in children.

METHODS

This systematic review was conducted in accordance with Cochrane Guidance. Database searches (January 1970- March 2021) were screened, abstracted, and assessed for risk of bias for comparative randomised controlled trials (RCTs) and non-randomised studies (NRSs) with >10 patients per group. Open cystolithotomy (CL), transurethral cystolithotripsy (TUCL), percutaneous cystolithotripsy (PCCL), extracorporeal shock wave lithotripsy (ESWL) and laparoscopic cystolithotomy (LapCL) were evaluated.

RESULTS

In total, 3040 abstracts were screened, and 8 studies were included. There were 7 retrospective non-randomised studies (NRS's) and 1 quasi-RCT with 1034 eligible patients (CL: n=637, TUCL: n=196, PCCL: n=138, ESWL: n=63, LapCL n=0). Stone free rate (SFR) was given in 7 studies and measured 100%, 86.6%-100%, and 100% for CL, TUCL and PCCL respectively. CL was associated with a longer duration of inpatient stay than PCCL and TUCL (p<0.05). One NRS showed that SFR was significantly lower after 1 session with outpatient ESWL (47.6%) compared to TUCL (93.5%) and CL (100%) (p<0.01 and p<0.01 respectively). One RCT compared TUCL with laser versus TUCL with pneumatic lithotripsy and found that procedure duration was shorter with laser for stones <1.5cm (n=25, p=0.04).

CONCLUSION

In conclusion, CL, TUCL and PCCL have comparable SFRs but ESWL is less effective for treating stones in paediatric patients. CL has the longest duration of inpatient stay. Information gathered from this systematic review will enable paediatric urologists to comparatively assess the risks and benefits of all urological modalities when considering surgical intervention for bladder stones.

Public perceptions of how alcohol consumption is dealt with in Swedish and Norwegian health care

Aims:

The aims of this study were to evaluate and compare popular beliefs and attitudes regarding alcohol conversations in healthcare in Sweden and Norway; and to explore which factors were associated with different levels of support for alcohol-prevention work in the two countries.

Methods:

Population-based cross-sectional surveys were conducted in Sweden (n = 3000) and Norway (n = 1208). Logistic regression was used to identify the characteristics of participants who were supportive of routine alcohol screening and brief intervention delivery.

Results:

A higher proportion of Swedish respondents agreed to a large extent that healthcare professionals should routinely ask about alcohol consumption. In addition, a higher proportion of Swedish respondents compared to respondents from Norway agreed that healthcare providers should only ask about patient’s alcohol consumption if this was related to specific symptoms. There were similar correlates of being supportive of routine alcohol screening and brief intervention delivery in both countries. Support was lower in both countries amongst moderate and risky drinkers, and among single adults or those on parental leave, but higher amongst older individuals. Having had an alcohol conversation in healthcare increased the level of support for alcohol prevention in routine healthcare among risky drinkers.

Conclusions:

There is a high level of support for preventative alcohol conversations in routine healthcare in Norway and Sweden, although there was a lower proportion of respondents who were positive to alcohol prevention in routine healthcare in Norway compared to Sweden. Experiencing alcohol conversation may positively affect risky drinkers’ attitudes towards and support for alcohol prevention. Thus, more frequent alcohol conversations in routine healthcare may also result in increased level of support for alcohol prevention among risky drinkers.

Healthcare Professionals’ Perceptions of Promoting Healthy Lifestyle Behaviors in Pregnant Migrant Women and the Potential of a Digital Support Tool—A Qualitative Study

Eating healthily and being physically active during pregnancy are important for maternal and offspring health. Maternity healthcare is a key arena for health promotion; however, 20% of pregnant women in Sweden are foreign-born, which may reduce reach due to language and cultural barriers. The aims of this study were to explore healthcare professionals’ perceptions about (a) promoting health behaviors (i.e., healthy diet, physical activity, and weight gain) among Arabic- and Somali-speaking pregnant women and (b) how a translated version of the previously evaluated Swedish app (HealthyMoms) can be tailored and used as a tool in their clinical work. Healthcare professionals in Swedish maternity care (n = 14) were interviewed. Data were analyzed using inductive thematic analysis. Healthcare professionals expressed challenges in health promotion work, including cultural and educational aspects and low awareness of health behaviors among women themselves and their social environment. Further, a lack of resources within the clinical practice and a need for cultural awareness among healthcare professionals were highlighted. Finally, it was perceived that a translated app has potential to provide basic and culturally adjusted information, facilitate communication and thus has potential to become a helpful tool in maternity care to support healthy lifestyle behaviors in Arabic- and Somali-speaking pregnant women.

Association of COVID-19 with impaired endothelial glycocalyx, vascular function and myocardial efficiency four months after infection

Funding Acknowledgements

Type of funding sources: None.

Aims

SARS-CoV-2 infection may lead to endothelial and vascular dysfunction. We

investigated alterations of arterial stiffness, endothelial coronary and myocardial

function markers four months after COVID-19 infection.

Methods

In a case-control prospective study, we included 100 patients four months after COVID-19 infection, 50 age- and sex-matched healthy individuals. We measured a) pulse wave velocity (PWV), b) flow-mediated dilation (FMD) of brachial artery, c) coronary Flow Reserve (CFR) by Doppler echocardiography d) left ventricular (LV) global longitudinal strain (GLS), e) left ventricular myocardial work index, constructive work, wasted work and work efficiency and e) von-Willenbrand factor and thrombomodulin as endothelial biomarkers.

Results

COVID-19 patients had lower CFR and FMD values than controls (2.39 ± 0.39 vs 3.31 ± 0.59, p = 0.0122, 5.12 ± 2.95% vs 8.12 ± 2.23%, p = 0.006 respectively). Compared to controls, COVID-19 patients had higher PWV (PWVc-f 12.32 ± 2.44 vs 10.11 ± 1.85 m/sec, p = 0.033) and impaired LV GLS (-19.11 ± 2.14% vs -20.41 ± 1.61%, p = 0.001). Compared to controls, COVID-19 patients had higher myocardial work index, and wasted work (2067.7 ± 325.9 mmHg% vs 1929.4 ± 312.7 mmHg%, p = 0.026, 104.6 ± 58.9 mmHg% vs 75.1 ± 52.6 mmHg%, p = 0.008, respectively), while myocardial efficiency was lower (94.8 ± 2.5% vs 96.06 ± 2.3%, p = 0.008). and thrombomodulin were higher in COVID-19 patients than controls (3716.63 ± 188.36 vs 2590.02 ± 156.51pg/ml, p &lt; 0.001). MDA was higher in COVID-19 patients than controls (10.55 ± 2.45 vs 1.01 ± 0.50 nmole/L, p = 0.001). Residual cardiovascular symptoms at 4 months were associated with oxidative stress markers. Myocardial work efficiency was related with PWV (F=-0.309, p = 0.016) and vWillenbrand (F=-0.541, p = 0.037). Myocardial wasted work was related with PWV (F = 0.255, p = 0.047) and vWillenbrand (F = 0.610, p = 0.016).

Conclusions

SARS-CoV-2 may cause vascular dysfunction, followed by a waste of cardiac work, in order to compensate for increased arterial stiffness 4 months after infection.

A Self-help Tool to Facilitate Implementation of eHealth Initiatives in Health Care (E-Ready): Formative Evaluation

BACKGROUND

eHealth interventions have the potential to increase the efficiency and effectiveness of health care. However, research has shown that implementing eHealth in routine health care practice is difficult. Organizational readiness to change has been shown to be central to successful implementation. This paper describes the development and formative evaluation of a generic self-help tool, E-Ready, designed to be used by managers, project leaders, or others responsible for implementation in a broad range of health care settings.

OBJECTIVE

The aim of this study is to develop and evaluate a tool that could facilitate eHealth implementation in, for example, health care.

METHODS

A first version of the tool was generated based on implementation theory (E-Ready 1.0). A formative evaluation was undertaken through expert panels (n=15), cognitive interviews (n=17), and assessment of measurement properties on E-Ready items from 3 different workplaces (n=165) using Rasch analyses. E-Ready 1.0 was also field tested among the target population (n=29). Iterative revisions were conducted during the formative evaluation process, and E-Ready 2.0 was generated.

RESULTS

The E-Ready Tool consists of a readiness assessment survey and a hands-on manual. The survey measures perceived readiness for change (willingness and capability) at individual and collective levels: perceived conditions for change at the workplace, perceived individual conditions for change, perceived support and engagement among management, perceived readiness among colleagues, perceived consequences on status quo, and perceived workplace attitudes. The manual contains a brief introduction, instructions on how to use the tool, information on the themes of E-Ready, instructions on how to create an implementation plan, brief advice for success, and tips for further reading on implementation theory. Rasch analyses showed overall acceptable measurement properties in terms of fit validity. The subscale Individual conditions for change (3 items) had the lowest person reliability (0.56), whereas Perceived consequences on status quo (5 items) had the highest person reliability (0.87).

CONCLUSIONS

E-Ready 2.0 is a new self-help tool to guide implementation targeting health care provider readiness and engagement readiness ahead of eHealth initiatives in, for example, health care settings. E-Ready can be improved further to capture additional aspects of implementation; improvements can also be made by evaluating the tool in a larger sample.

Organizational readiness to implement a care model in primary care for frail older adults living at home in Sweden

Background

The demographic change of an aging population constitutes a challenge for primary care organizations worldwide. The systematic implementation of preventative and proactive care models is needed to cope with increased care demands.

Objective

To investigate the organizational readiness in primary care to implement a new care model to prevent hospitalization among frail older adults.

Method

Individual qualitative interviews with health care staff investigated organizational readiness at seven primary care units in Sweden. A semi-structured interview guide was used during the interviews and included broad questions on individual and collective readiness to change. Directed content analysis and organizational readiness to change theory were used in data analysis.

Results

Positive beliefs among staff such as perceived benefits and compatibility with existing values contributed to a strong commitment to implement the new care model. However, perceptions such as unclear task demands, limited resources and concerns about new collaborative structures challenged implementation.

Conclusions

The findings emphasize implementation as an inter-organizational phenomenon, especially for holistic practices that span across multiple health care providers and disciplines. Furthermore, implementing care models in healthcare may require a change of culture as much as a change of practice.

Mobile phone-based lifestyle support for families with young children in primary health care (MINISTOP 2.0): Exploring behavioral change determinants for implementation using the COM-B model

Background

Obesity in childhood is a public health concern worldwide and mobile phone-based interventions (mHealth) has shown to facilitate obesity prevention. However, more research is needed on the implementation of digital tools in routine primary care. This study explored behavior change determinants for implementing a health promotion mHealth intervention (MINISTOP 2.0 app) targeting parents of 4-year-olds.

Methods

Secondary data from telephone interviews (n = 15) with child health care nurses working within primary child healthcare in Sweden was analyzed using directed content analysis and the COM-B model.

Results

Barriers for implementation included: limited knowledge about using technology and reservations about how and to what extent parents would use mHealth. Potential facilitators included nurses' openness to learn and try new tools, confidence in their role and engagement in reaching parents as well as beliefs that the app could improve practice by prompting dialogue and being a shared platform. Nurses expressed a strong professional identity and shared understanding of their practice, mechanisms that could potentially inhibit or facilitate implementation.

Conclusions

Findings suggest cautious optimism regarding implementing mobile phone-based tools in child primary healthcare in terms of capability, opportunity and motivation among stakeholders. Implementation strategies such as educational outreach visits and making the intervention testable among stakeholders could further facilitate implementation in this clinical context. However, more research is needed on behavior change determinants in different stages of real-world implementation.

Evaluation of an online toolkit for carers of people with a life-limiting illness at the end-of-life: health professionals' perspectives

Carers of people with a life-limiting illness report unmet information, practical, and emotional support needs, and are often unaware of services available to help improve preparedness, wellbeing, and reduce strain. CarerHelp is the first e-health toolkit that focuses on the information and support needs of carers of people with a life-limiting illness at the end-of-life, using a pathway approach. This study investigated the usefulness of CarerHelp, from the perspective of health professionals who care for these people. Through a 10-min online survey, health professionals provided feedback about their user experience and perceived usefulness of the website. Their expert opinion was sought to ascertain whether CarerHelp could increase carers' preparedness and confidence to support the person for whom they are caring and thereby improve carers' own psychological wellbeing. Health professionals also evaluated whether CarerHelp adequately raised awareness of support services available. CarerHelp was perceived as a useful resource for increasing preparedness for the caring role, including physical tasks and emotional support. Health professionals reported that CarerHelp would increase carers' knowledge of services, confidence to care and ability for self-care. Health professionals endorsed CarerHelp as a useful information source, guide for support, and would promote CarerHelp to clients and their families.

Addressing Patients' Alcohol Consumption-A Population-Based Survey of Patient Experiences

Objectives: To identify the proportion of the population that had experienced that alcohol was addressed in health care the previous year, to explore experiences and perceived effects of addressing alcohol, and to investigate the proportion of risky drinkers in the population. Methods: Cross-sectional national web-based survey with 1,208 participants. Socio-demographic data, alcohol consumption (AUDIT-C), and experiences with alcohol conversations were investigated. Results: Approximately four in five respondents had visited health care the past 12 months, and one in six reported having experienced addressing alcohol. Women and older respondents were less likely to report having experienced alcohol conversations compared to other groups. Risky drinkers were not more likely to have experienced an alcohol conversation, but reported longer duration of alcohol conversations and more frequently perceived addressing alcohol as awkward or judgmental. Almost a third of respondents were classified as risky drinkers. Conclusion: The proportion experiencing addressing alcohol in routine health care is low, also among risky drinkers, and risky drinkers more frequently experienced the conversations as judgmental. More sensitive and relevant ways of addressing alcohol in health care is needed.

COVID-19 patients present impaired endothelial glycocalyx, vascular dysfunction and myocardial deformation resembling those observed in hypertensives four months after infection

Background/Introduction

COVID-19 infection has been associated with increase arterial stiffness, endothelial dysfunction, and impairment in coronary and cardiac performance. Inflammation and oxidative stress have been suggested as possible pathophysiological mechanisms leading to vascular and endothelial deregulation after COVID-19 infection.

Purpose

The objective of our study is to evaluate premature alterations in arterial stiffness, endothelial, coronary, and myocardial function markers four months after SARS-CoV-2 infection.

Methods

We conducted a case-control prospective study, including 70 patients four months after COVID-19 infection, 70 age- and sex-matched untreated hypertensive patients (positive control) and 70 healthy individuals. We measured a) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced endothelial glycocalyx thickness b) flow-mediated dilation (FMD), c) coronary Flow Reserve (CFR) by Doppler echocardiography d) pulse wave velocity (PWV) and central systolic (SBP) e) global LV longitudinal strain (GLS) by speckle tracking imaging and f) malondialdehyde (MDA) as oxidative stress marker.

Results

COVID-19 patients had similar CFR and FMD with hypertensives (2.48±0.41 vs 2.58±0.88, p=0.562, 5.86±2.82% vs 5.80±2.07%, p=0.872 respectively), but lower CFR and FMD than controls (3.42±0.65, p=0.0135 9.06±2.11%, p=0.002 respectively) Both COVID-19 and hypertensive group had greater PBR than controls (PBR5–25: 2.07±0.15 μm and 2.07±0.26 μm p=0.8 vs 1.89±0.17 μm, p=0.001). COVID-19 patients and hypertensives had higher PWV and central SBP than controls (PWVcf 12.09±2.50 and 11.92±2.94, p=0.7 vs 10.04±1.80 m/sec, p=0.036). COVID-19 patients and hypertensives had impaired values of GLS compared to controls (−19.50±2.56% and −19.23±2.67%, p=0.864 vs −21.98±1.51%, p=0.020). Increased PBR5–25 was associated with increased SBP central which in turn was related with impaired GLS (p<0.05). MDA was found increased in COVID-19 patients compared to both hypertensives and controls (10.67±2.75 vs 1.76±0.30, p=0.003 vs 1.01±0.50 nmole/L, p=0.001).

Conclusions

SARS-CoV-2 may cause impaired coronary microcirculatory, endothelial and vascular deregulation which remain four months after initial infection and are associated with reduced cardiac performance. The 10-fold increase of MDA compared to healthy individuals four months after COVID-19 infection indicate oxidative stress as possible pathophysiological mechanism.

733 Long-Term Outcomes of Outpatient Laser Ablation for Recurrent Non-Muscle Invasive Bladder Cancer: A Retrospective Cohort Study

Aim

Non-muscle-invasive bladder cancer (NMIBC) is the most prevalent form of bladder cancer, predominantly affecting the elderly population. The most common treatment for recurrent NMIBC is transurethral resection of the bladder tumour (TURBT), which carries a risk of perioperative morbidity and mortality in this often-co-morbid population. Outpatient laser ablation of low-grade NMIBC recurrences is a minimally invasive treatment option, but long-term efficacy is poorly reported.

Method

We retrospectively reviewed the case notes of all patients treated with Holmium:YAG laser ablation from 2008-2016. Data regarding patient demographics, original histology, dates of procedures, follow-up time, recurrence, progression, and complications were recorded.

Results

A total of 199 procedures were performed on 97 patients (mean age of 83.56), 73 (75.3%) of which originally had low-grade (G1 or G2) tumours. Overall, 55 (56.7%) patients developed tumour recurrence at long-term follow-up (mean 5.36 years), and only 9 (9.3%) patients had tumour progression to a higher stage or grade, but there was no progression to muscle-invasive disease. The median recurrence-free, progression-free and overall survival times were 1.69 years (95% CI 1.20-2.25), 5.70 years (95% CI 4.10-7.60) and 7.60 years (95% CI 4.90-8.70), respectively. No patients required emergency inpatient admission after laser ablation for any associated complications.

Conclusions

Office-based Holmium: YAG laser ablation is an oncologically-safe method of managing recurrent low-grade non-muscle-invasive bladder cancer in the long-term, with no patients progressing to muscle-invasive disease. Furthermore, the procedure is safe, and no significant complications were seen in this elderly and co-morbid population.

Mental health improvements after elective spine surgery: a Canadian Spine Outcome Research Network (CSORN) study

BACKGROUND CONTEXT

Spine patients have a higher rate of depression then the general population which may be caused in part by levels of pain and disability from their spinal disease.

PURPOSE

Determination whether improvements in health-related quality of life (HRQOL) resulting from successful spine surgery leads to improvements in mental health.

STUDY DESIGN/SETTING

The Canadian Spine Outcome Research Network prospective surgical outcome registry.

OUTCOME MEASURES

Change between preoperative and postoperative SF12 Mental Component Score (MCS). Secondary outcomes include European Quality of Life (EuroQoL) Healthstate, SF-12 Physical Component Score (PCS), Oswestry Disability Index (ODI), Patient Health Questionaire-9 (PHQ9), and pain scales.

METHODS

The Canadian Spine Outcome Research Network registry was queried for all patients receiving surgery for degenerative thoracolumbar spine disease. Exclusion criteria were trauma, tumor, infection, and previous spine surgery. SF12 Mental Component Scores (MCS) were compared between those with and without significant improvement in postoperative disability (ODI) and secondary measures. Multivariate analysis examined factors predictive of MCS improvement.

RESULTS

Eighteen hospitals contributed 3222 eligible patients. Worse ODI, EuroQoL, PCS, back pain and leg pain correlated with worse MCS at all time points. Overall, patients had an improvement in MCS that occurred within 3 months of surgery and was still present 24 months after surgery. Patients exceeding Minimally Clinically Important Differences in ODI had the greatest improvements in MCS. Major depression prevalence decreased up to 48% following surgery, depending on spine diagnosis.

CONCLUSIONS

Large scale, real world, registry data suggests that successful surgery for degenerative lumbar disease is associated with reduction in the prevalence of major depression regardless of the specific underlaying diagnosis. Worse baseline MCS was associated with worse baseline HRQOL and improved postoperatively with coincident improvement in disability, emphasizing that mental wellness is not a static state but may improve with well-planned spine surgery.

mHealth intervention for multiple lifestyle behaviour change among high school students in Sweden (LIFE4YOUth): protocol for a randomised controlled trial

Background

National surveys in Sweden demonstrate that the majority of young people do not engage in health promoting behaviours at levels recommended by the Public Health Agency of Sweden. The objective of this study is to estimate the effectiveness of a novel mHealth intervention named LIFE4YOUth, which targets multiple lifestyle behaviours (alcohol, diet, physical activity, and smoking) among high school students in Sweden.

Methods

A 2-arm parallel groups single blind randomised controlled trial (1:1) will be employed to estimate the effectiveness of the novel mHealth intervention. Students will be recruited at high schools throughout Sweden, and will be included if they fulfil one of six criteria relating to unhealthy behaviours with respect to alcohol, diet, physical activity and smoking. Eligible participants will be randomised to either receive the novel intervention immediately, or to be placed on a waiting list for 4 months. The intervention consists of a combination of recurring screening, text messages, and an interactive platform which is adaptable to individual preferences. Outcome measures with respect to alcohol, diet, physical activity and smoking will be assessed through questionnaires at 2 and 4 months post randomisation.

Discussion

The findings of this trial could be generalised to a diverse high-school student population as our recruitment encompass a large proportion of schools throughout Sweden with various educational profiles. Furthermore, if effective, the mHealth intervention has good potential to be able to be scaled up and disseminated at high schools nationally.

Depressive symptoms postpartum is associated with physical activity level the year prior to giving birth - A retrospective observational study

OBJECTIVES

To examine physical activity level prior to pregnancy, during pregnancy and postpartum and investigate the association with depressive symptoms postpartum among women in Sweden.

STUDY DESIGN

Retrospective observational study including 532 women on self-assessment of physical activity level before pregnancy, during pregnancy and postpartum, depressive symptoms postpartum as well as stressful life events in the past two years.

MAIN OUTCOME MEASURES

Level and change of physical activity before pregnancy, during pregnancy and postpartum and depressive symptoms postpartum.

RESULTS

Almost two-thirds of the women in the study reported that they were inactive or performed light physical activity (62.9%; n = 331) in the year prior to giving birth. Women with a sedentary lifestyle or performing light physical activity level reported depressive symptoms postpartum to a greater extent than active women.

CONCLUSIONS

A higher level of physical activity during pregnancy was associated with a lower level of depressive symptoms postpartum. Physical activity is a contributing factor to promote a healthier lifestyle and can contribute to improve mental health for pregnant women, newly become mothers and their children.

Adapting a Parental Support App to Promote Healthy Diet and Physical Activity Behaviors (MINISTOP) for a Multi-Ethnic Setting: A Qualitative Study on the Needs and Preferences of Parents and Nurses within Swedish Child Health Care

Early efforts for prevention of childhood overweight and obesity are needed. In order to adapt an app promoting healthy diet and physical activity behaviors in children (MINISTOP 1.0) for multi-ethnic communities, we explored: (1) needs and concerns among Somali-, Arabic-, and Swedish-speaking parents in terms of supporting healthy diet and activity behaviors in their children; (2) nurses’ perceptions of parental needs and concerns in relation to diet and physical activity behaviors; and (3) how the features and content of the MINISTOP 1.0 app could be refined to better support health behaviors in children, among both parents and nurses. Focus groups with Somali-, Arabic-, and Swedish-speaking parents (n = 15), and individual interviews with nurses (n = 15) were conducted. Parents expressed several challenges in supporting children’s health behaviors, the need for a tailored app, and alternative ways of accessing the content (audio/video). Nurses emphasized the need of supporting parents early, and the value of a shared platform in different languages, to facilitate communication. This study contributes valuable insights about parental needs and relevant adaptations to a parental support app, such as addition of audio/video files for increased accessibility. This adapted app version—MINISTOP 2.0, can be useful for childhood obesity prevention in multi-ethnic communities.

Randomised controlled trial of oxygen therapy and high-flow nasal therapy in African children with pneumonia

Purpose

The life-saving role of oxygen therapy in African children with severe pneumonia is not yet established.

Methods

The open-label fractional-factorial COAST trial randomised eligible Ugandan and Kenyan children aged > 28 days with severe pneumonia and severe hypoxaemia stratum (SpO₂ < 80%) to high-flow nasal therapy (HFNT) or low-flow oxygen (LFO: standard care) and hypoxaemia stratum (SpO₂ 80–91%) to HFNT or LFO (liberal strategies) or permissive hypoxaemia (ratio 1:1:2). Children with cyanotic heart disease, chronic lung disease or > 3 h receipt of oxygen were excluded. The primary endpoint was 48 h mortality; secondary endpoints included mortality or neurocognitive sequelae at 28 days.

Results

The trial was stopped early after enrolling 1852/4200 children, including 388 in the severe hypoxaemia stratum (median 7 months; median SpO₂ 75%) randomised to HFNT (n = 194) or LFO (n = 194) and 1454 in the hypoxaemia stratum (median 9 months; median SpO₂ 88%) randomised to HFNT (n = 363) vs LFO (n = 364) vs permissive hypoxaemia (n = 727). Per-protocol 15% of patients in the permissive hypoxaemia group received oxygen (when SpO₂ < 80%). In the severe hypoxaemia stratum, 48-h mortality was 9.3% for HFNT vs. 13.4% for LFO groups. In the hypoxaemia stratum, 48-h mortality was 1.1% for HFNT vs. 2.5% LFO and 1.4% for permissive hypoxaemia. In the hypoxaemia stratum, adjusted odds ratio for 48-h mortality in liberal vs permissive comparison was 1.16 (0.49–2.74; p = 0.73); HFNT vs LFO comparison was 0.60 (0.33–1.06; p = 0.08). Strata-specific 28 day mortality rates were, respectively: 18.6, 23.4 and 3.3, 4.1, 3.9%. Neurocognitive sequelae were rare.

Conclusions

Respiratory support with HFNT showing potential benefit should prompt further trials.

Laser therapy is a safe and effective treatment for unwanted hair in adults undergoing male to female sex reassignment

Reduction in unwanted facial and body hair is an important goal in the process of sex reassignment. Laser treatment is a popular, well-established safe and effective method of reducing unwanted hair growth. In the UK a limited number of laser treatment and electrolysis sessions are publically funded for people undergoing sex reassignment. To date, published evidence on efficacy and adverse effects (AEs) has focused on treatment of women and men not undergoing sex reassignment. In the current study, data were collected prospectively from 2015 to 2020 at a UK regional laser centre. Patients were included if they were transgender women aged > 16 years old and seeking laser treatment for unwanted hair at any body site. The study demonstrated significant reductions in hair growth and significant patient satisfaction, with no AEs. Laser treatment is a safe and effective method of managing unwanted hair growth in the transgender transfeminine population.

A neural network to predict the knee adduction moment in patients with osteoarthritis using anatomical landmarks obtainable from 2D video analysis

OBJECTIVE

The knee adduction moment (KAM) can inform treatment of medial knee osteoarthritis; however, measuring the KAM requires an expensive gait analysis laboratory. We evaluated the feasibility of predicting the peak KAM during natural and modified walking patterns using the positions of anatomical landmarks that could be identified from video analysis.

METHOD

Using inverse dynamics, we calculated the KAM for 86 individuals (64 with knee osteoarthritis, 22 without) walking naturally and with foot progression angle modifications. We trained a neural network to predict the peak KAM using the 3-dimensional positions of 13 anatomical landmarks measured with motion capture (3D neural network). We also trained models to predict the peak KAM using 2-dimensional subsets of the dataset to simulate 2-dimensional video analysis (frontal and sagittal plane neural networks). Model performance was evaluated on a held-out, 8-person test set that included steps from all trials.

RESULTS

The 3D neural network predicted the peak KAM for all test steps with r2( Murray et al., 2012) 2 = 0.78. This model predicted individuals' average peak KAM during natural walking with r2( Murray et al., 2012) 2 = 0.86 and classified which 15° foot progression angle modifications reduced the peak KAM with accuracy = 0.85. The frontal plane neural network predicted peak KAM with similar accuracy (r2( Murray et al., 2012) 2 = 0.85) to the 3D neural network, but the sagittal plane neural network did not (r2( Murray et al., 2012) 2 = 0.14).

CONCLUSION

Using the positions of anatomical landmarks from motion capture, a neural network accurately predicted the peak KAM during natural and modified walking. This study demonstrates the feasibility of measuring the peak KAM using positions obtainable from 2D video analysis.

CT diagnosis of ilioinguinal lymph node metastases in melanoma using radiological characteristics beyond size and asymmetry

Background

Diagnosis of lymph node (LN) metastasis in melanoma with non-invasive methods is challenging. The aim of this study was to evaluate the diagnostic accuracy of six LN characteristics on CT in detecting melanoma-positive ilioinguinal LN metastases, and to determine whether inguinal LN characteristics can predict pelvic LN involvement.

Methods

This was a single-centre retrospective study of patients with melanoma LN metastases at a tertiary cancer centre between 2008 and 2016. Patients who had preoperative contrast-enhanced CT assessment and ilioinguinal LN dissection were included. CT scans containing significant artefacts obscuring the pelvis were excluded. CT scans were reanalysed for six LN characteristics (extracapsular spread (ECS), minimum axis (MA), absence of fatty hilum (FH), asymmetrical cortical nodule (CAN), abnormal contrast enhancement (ACE) and rounded morphology (RM)) and compared with postoperative histopathological findings.

Results

A total of 90 patients were included. Median age was 58 (range 23–85) years. Eighty-eight patients (98 per cent) had pathology-positive inguinal disease and, of these, 45 (51 per cent) had concurrent pelvic disease. The most common CT characteristics found in pathology-positive inguinal LNs were MA greater than 10 mm (97 per cent), ACE (80 per cent), ECS (38 per cent) and absence of RM (38 per cent). In multivariable analysis, inguinal LN characteristics on CT indicative of pelvic disease were RM (odds ratio (OR) 3.3, 95 per cent c.i. 1.2 to 8.7) and ECS (OR 4.2, 1.6 to 11.3). Cloquet’s node is known to be a poor predictor of pelvic spread. Pelvic LN disease was present in 50 per cent patients, but only 7 per cent had a pathology-positive Cloquet’s node.

Conclusion

Additional CT radiological characteristics, especially ECS and RM, may improve diagnostic accuracy and aid clinical decisions regarding the need for inguinal or ilioinguinal dissection.

Genome-wide surveillance of transcription errors in response to genotoxic stress

Mutagenic compounds are a potent source of human disease. By inducing genetic instability, they can accelerate the evolution of human cancers or lead to the development of genetically inherited diseases. Here, we show that in addition to genetic mutations, mutagens are also a powerful source of transcription errors. These errors arise in dividing and nondividing cells alike, affect every class of transcripts inside cells, and, in certain cases, greatly exceed the number of mutations that arise in the genome. In addition, we reveal the kinetics of transcription errors in response to mutagen exposure and find that DNA repair is required to mitigate transcriptional mutagenesis after exposure. Together, these observations have far-reaching consequences for our understanding of mutagenesis in human aging and disease, and suggest that the impact of DNA damage on human physiology has been greatly underestimated.

Idiopathic systemic capillary leak syndrome (Clarkson's disease) presenting with recurrent hypovolemic shock

A 49-year old male with a past medical history of myocardial infarction and compartment syndromes requiring fasciotomies presented on five occasions with hypovolemic shock. We describe his admissions and presumptive diagnoses which required large volumes of intravenous fluids, admission to intensive care for vasopressors and renal replacement therapy. The presentations were always precipitated by a prodrome of fatigue and pre-syncopal episodes. On his last admission, a diagnosis of Idiopathic systemic capillary leak syndrome (ISCLS), also known as Clarkson's Disease, was reached. He is currently receiving high dose intravenous immunoglobulins on a monthly basis.

Novel community health worker strategy for HIV service engagement in a hyperendemic community in Rakai, Uganda: A pragmatic, cluster-randomized trial

BACKGROUND

Effective implementation strategies are needed to increase engagement in HIV services in hyperendemic settings. We conducted a pragmatic cluster-randomized trial in a high-risk, highly mobile fishing community (HIV prevalence: approximately 38%) in Rakai, Uganda, to assess the impact of a community health worker-delivered, theory-based (situated Information, Motivation, and Behavior Skills), motivational interviewing-informed, and mobile phone application-supported counseling strategy called "Health Scouts" to promote engagement in HIV treatment and prevention services.

METHODS AND FINDINGS

The study community was divided into 40 contiguous, randomly allocated clusters (20 intervention clusters, n = 1,054 participants at baseline; 20 control clusters, n = 1,094 participants at baseline). From September 2015 to December 2018, the Health Scouts were deployed in intervention clusters. Community-wide, cross-sectional surveys of consenting 15 to 49-year-old residents were conducted at approximately 15 months (mid-study) and at approximately 39 months (end-study) assessing the primary programmatic outcomes of self-reported linkage to HIV care, antiretroviral therapy (ART) use, and male circumcision, and the primary biologic outcome of HIV viral suppression (<400 copies/mL). Secondary outcomes included HIV testing coverage, HIV incidence, and consistent condom use. The primary intent-to-treat analysis used log-linear binomial regression with generalized estimating equation to estimate prevalence risk ratios (PRR) in the intervention versus control arm. A total of 2,533 (45% female, mean age: 31 years) and 1,903 (46% female; mean age 32 years) residents completed the mid-study and end-study surveys, respectively. At mid-study, there were no differences in outcomes between arms. At end-study, self-reported receipt of the Health Scouts intervention was 38% in the intervention arm and 23% in the control arm, suggesting moderate intervention uptake in the intervention arm and substantial contamination in the control arm. At end-study, intention-to-treat analysis found higher HIV care coverage (PRR: 1.06, 95% CI: 1.01 to 1.10, p = 0.011) and ART coverage (PRR: 1.05, 95% CI: 1.01 to 1.10, p = 0.028) among HIV-positive participants in the intervention compared with the control arm. Male circumcision coverage among all men (PRR: 1.05, 95% CI: 0.96 to 1.14, p = 0.31) and HIV viral suppression among HIV-positive participants (PRR: 1.04, 95% CI: 0.98 to 1.12, p = 0.20) were higher in the intervention arm, but differences were not statistically significant. No differences were seen in secondary outcomes. Study limitations include reliance on self-report for programmatic outcomes and substantial contamination which may have diluted estimates of effect.

CONCLUSIONS

A novel community health worker intervention improved HIV care and ART coverage in an HIV hyperendemic setting but did not clearly improve male circumcision coverage or HIV viral suppression. This community-based, implementation strategy may be a useful component in some settings for HIV epidemic control.

Effects of a Text Messaging Smoking Cessation Intervention Among Online Help Seekers and Primary Health Care Visitors in Sweden: Protocol for a Randomized Controlled Trial Using a Bayesian Group Sequential Design

BACKGROUND

A steady decline of the smoking prevalence in Sweden has been recorded over the past decade; however, people still start and continue to smoke. There is a need for effective smoking cessation interventions that can scale to a national level and that are designed to reach individuals requiring smoking cessation support in the general population.

OBJECTIVE

Previous randomized controlled trials of smoking cessation interventions among high school and university students in Sweden have found consistent evidence that text messaging interventions are effective in helping students quit smoking. However, there are no studies that investigate the effects of text messaging interventions in a more general population. The objective of this study is to estimate the effects of a text messaging intervention on individuals seeking help to quit online and individuals visiting primary health care units.

METHODS

A 2-arm, parallel-group (1:1), randomized controlled trial will be employed to address the study objectives. The trial will follow a Bayesian group sequential design. Recruitment will be conducted using online advertisement (Google, Bing, and Facebook) and through health care professionals at primary health care units. All participants will receive treatment as usual; however, participants who are allocated to the intervention arm will also be given access to a 12-week text message smoking cessation intervention. Primary outcomes are 8-week prolonged abstinence and 4-week point prevalence, measured 3 months and 6 months postrandomization. Mediator variables (self-efficacy, importance, and know-how) will be measured to estimate causal mediation models.

RESULTS

Recruitment commenced in September 2020 and will not exceed 24 months. This means that a complete dataset will be available at the latest towards the end of 2022. We expect to publish the findings from this trial by June 2023.

CONCLUSIONS

This trial will further our understanding of the effects of text messaging interventions among a more general population than has previously been studied. We also aim to learn about differential effects between those who seek support online and those who are given facilitated support at primary health care units. Trial recruitment is limited to the Swedish population; however, a strength of this study is the pragmatic way in which participants are recruited. Through online advertisements, individuals are recruited in reaction to their own interest in seeking help to quit. At primary health care units, individuals who were not necessarily looking for smoking cessation support are given information about the trial. This closely mimics the way the intervention would be disseminated in a real-world setting and may therefore strengthen the argument of generalizability of findings.

MINISTOP 2.0: a smartphone app integrated in primary child health care to promote healthy diet and physical activity behaviours and prevent obesity in preschool-aged children: protocol for a hybrid design effectiveness-implementation study

Background

Childhood obesity is still a major health problem in many countries, including Sweden. Childhood obesity and obesity-related behaviours in childhood, such as low physical activity and unhealthy eating habits, tend to track into adulthood, which highlights the need for early prevention. Our aims are to evaluate whether a parent-oriented mobile health app (the MINISTOP 2.0 app) integrated into primary child health care can improve diet and physical activity behaviours and reduce the prevalence of overweight and obesity in preschool-aged children as well as to evaluate the implementation among child health care nurses and parents.

Methods

This trial uses a hybrid type 1 effectiveness-implementation design. Families (n = 500) who attend a routine visit to one of 15–20 primary child health care centres throughout Sweden, when their child is 2.5 years, are offered participation in a randomised controlled trial (effectiveness evaluation). After acceptance, families will be randomised (1:1) to control or intervention groups. The intervention group receives a 6-month parent-oriented smartphone intervention aimed at improving the dietary and activity behaviours of their child (the MINISTOP 2.0 app) and the control group receives routine child health care. Dietary habits, physical activity and screen time (primary outcomes), body weight and height in children, and parental self-efficacy (secondary outcomes) are measured at baseline and at 6 months post randomisation. Implementation outcomes (i.e. perceived acceptability, appropriateness, and feasibility) of the intervention will be assessed among primary child health care nurses and parents in the trial through questionnaires and qualitative interviews.

Discussion

This trial will evaluate whether the MINISTOP 2.0 app can be used in primary child health care to improve diet and physical activity behaviours, and prevent overweight and obesity, in preschool-aged children. If effectiveness is proven, and the MINISTOP 2.0 app is considered acceptable, appropriate and feasible, it can be implemented nationally as part of the preventive strategies to combat childhood obesity provided by routine child health care.

Trial registration

The trial was registered at the Clinicaltrials.gov register platform (ID NCT04147039) on 31 October 2019.

Development of an Intervention Targeting Multiple Health Behaviors Among High School Students: Participatory Design Study Using Heuristic Evaluation and Usability Testing

Background

Mobile electronic platforms provide exciting possibilities for health behavior promotion. For instance, they can promote smoking cessation, moderate alcohol consumption, healthy eating, and physical activity. Young adults in Sweden are proficient in the use of technology, having been exposed to computers, smartphones, and the internet from an early age. However, with the high availability of mobile health (mHealth) interventions of varying quality, it is critical to optimize the usability of mHealth interventions to ensure long-term use of these health promotion interventions.

Objective

This study aims to investigate the usability of an mHealth intervention (LIFE4YOUth) targeting health behaviors among high school students through heuristic evaluation and usability testing.

Methods

A preliminary version of the LIFE4YOUth mHealth intervention, which was aimed at promoting healthy eating, physical activity, smoking cessation, and nonrisky drinking among high school students, was developed in early 2019. We completed a total of 15 heuristic evaluations and 5 usability tests to evaluate the usability of the mHealth intervention prototype to improve its functioning, content, and design.

Results

Heuristic evaluation from a total of 15 experts (10 employees and 5 university students, both women and men, aged 18-25 years) revealed that the major usability problems and the worst ratings, a total of 17 problems termed usability catastrophes, concerned shortcomings in displaying easy-to-understand information to the users or technical errors. The results of the usability testing including 5 high school students (both girls and boys, aged 15-18 years) showed that the design, quality, and quantity of content in the intervention may impact the users’ level of engagement. Poor functionality was considered a major barrier to usability. Of the 5 participants, one rated the LIFE4YOUth intervention as poor, 2 rated as average, and 2 assessed it as good, according to the System Usability Scale.

Conclusions

High school students have high expectations of digital products. If an mHealth intervention does not offer optimal functions, they may cease to use it. Optimizing the usability of mHealth interventions is a critical step in the development process. Heuristic evaluation and usability testing in this study provided valuable knowledge about the prototype from a user’s perspective. The findings may lead to the development of similar interventions targeting the high school population.

Implementing Facilitated Access to a Text Messaging, Smoking Cessation Intervention Among Swedish Patients Having Elective Surgery: Qualitative Study of Patients' and Health Care Professionals' Perspectives

Background

There is strong evidence that short-term smoking cessation before surgery can reduce postoperative morbidity. There are, however, several structural problems in health care systems concerning how to implement smoking cessation interventions in routine practice for preoperative patients.

Objective

This study aimed to analyze the implementation of a text messaging, smoking cessation intervention targeting patients having elective surgery. Implementation of facilitated access (ie, referral from practitioners) and the perceived usefulness among patients were investigated. Elective surgery is defined as scheduled, nonacute surgery.

Methods

A qualitative study was carried out at two medium-sized hospitals in the south of Sweden. The implementation of facilitated access was investigated during a 12-month period from April 2018 to April 2019. Facilitated access was conceptualized as specialists recommending the text messaging intervention to patients having elective surgery. Implementation was explored in terms of perceptions about the intervention and behaviors associated with implementation; that is, how patients used the intervention and how specialists behaved in facilitating usage among patients. Two focus groups with smoking cessation specialists and 10 individual interviews with patients were carried out. Qualitative content analysis was used to analyze the data.

Results

Two main categories were identified from the focus group data with smoking cessation specialists: implementation approach and perceptions about the intervention. The first category, implementation approach, referred to how specialists adapted their efforts to situational factors and to the needs and preferences of patients, and how building of trust with patients was prioritized. The second category, perceptions about the intervention, showed that specialists thought the content and structure of the text messaging intervention felt familiar and worked well as a complement to current practice. Two categories were identified from the patient interview data: incorporating new means of support from health care and determinants of use. The first category referred to how patients adopted and incorporated the intervention into their smoking cessation journey. Patients were receptive, shared the text messages with friends and family, humanized the text messages, and used the messages as a complement to other strategies to quit smoking. The second category, determinants of use, referred to aspects that influenced how and when patients used the intervention and included the following: timing of the intervention and text messages, motivation to change, and perceptions of the mobile phone medium.

Conclusions

Smoking cessation specialists adopted an active role in implementing the intervention by adapting their approach and fitting the intervention into existing routines. Patients showed strong motivation to change and openness to incorporate the intervention into their behavior change journey; however, the timing of the intervention and messages were important in optimizing the support. A text messaging, smoking cessation intervention can be a valuable and feasible way to reach smoking patients having elective surgery.
