Background

According to the Medical Research Council (MRC) framework, the theorisation of how multilevel, multicomponent interventions work and the understanding of their interaction with their implementation context are necessary to be able to evaluate them beyond their complexity. More research is needed to provide good examples following this approach in order to produce evidence-based information on implementation practices.

Objectives

This article reports on the results of the process evaluation of a complex mental health intervention in small and medium enterprises (SMEs) tested through a pilot study. The overarching aim is to contribute to the evidence base related to the recruitment, engagement and implementation strategies of applied mental health interventions in the workplace.

Method

The Mental Health Promotion and Intervention in Occupational Settings (MENTUPP) intervention was pilot tested in 25 SMEs in three work sectors and nine countries. The evaluation strategy of the pilot test relied on a mixed-methods approach combining qualitative and quantitative research methods. The process evaluation was inspired by the RE-AIM framework and the taxonomy of implementation outcomes suggested by Proctor and colleagues and focused on seven dimensions: reach, adoption, implementation, acceptability, appropriateness, feasibility and maintenance.

Results

Factors facilitating implementation included the variety of the provided materials, the support provided by the research officers (ROs) and the existence of a structured plan for implementation, among others. Main barriers to implementation were the difficulty of talking about mental health, familiarisation with technology, difficulty in fitting the intervention into the daily routine and restrictions caused by COVID-19.

Conclusions

The results will be used to optimise the MENTUPP intervention and the theoretical framework that we developed to evaluate the causal mechanisms underlying MENTUPP. Conducting this systematic and comprehensive process evaluation contributes to the enhancement of the evidence base related to mental health interventions in the workplace and it can be used as a guide to overcome their contextual complexity.

Intervention of muscle-building and antifrailty exercise combined with Baduanjin for frailty of different functional levels: study protocol for a randomised controlled trial

Por: Xu · S. · Gong · Z. · Wang · F. · Cao · M. · Liu · J. · Chen · C. · Zhang · N. · Kang · J. · Xu · C. · Peng · N.
Introduction

Frailty has been currently considered as a multidimensional concept, including physical, cognitive and social frailty. Frailty has also been associated with a range of adverse events, which might increase the risks of disability, falls, fractures, delirium and death. Increasing evidence has shown that multicomponent exercise training can improve physical and cognitive function, delay or reverse frailty. However, there is still a lack of exercise intervention programmes for the frail older adults in China. This trial aims to investigate the effects of the muscle-building and antifrailty exercise combined with Baduanjin on the physical function of frail older adults, as well as the effectiveness and safety of the intervention.

Methods and analysis

This study is a prospective randomised controlled trial. A total of 192 patients, aged 70 years or older, who are diagnosed as prefrailty or frailty based on the Fried criteria will be included. Prior written and informed consent will be obtained from every subject. These subjects will be randomly assigned to the exercise intervention group (n=96) and the control group (n=96). The exercise intervention group will undergo different exercise programmes for different levels of physical function. They will perform the muscle-building and antifrailty exercise three times per week for 30–60 min for 24 weeks. The control group will implement health education on frailty and maintain the old lifestyle without any intervention.

The primary outcomes include the change in frailty and functional capacity, assessed according to the Fried Scale and the Short Physical Performance Battery. Secondary outcomes include the changes in body composition, Activities of daily living, Mini-Mental State Examination, The Geriatric Depression Scale-15 and the haematological indicators.

Ethics statement

The study has been approved by the Medical Ethics Committee of the PLA General Hospital (approval no.: S2022-600-02).

The Oxford Needle Experience (ONE) scale: a UK-based and US-based online mixed-methods psychometric development and validation study of an instrument to assess needle fear, attitudes and expectations in the general public

Por: Kantor · J. · Vanderslott · S. · Morrison · M. · Pollard · A. J. · Carlisle · R. C.
Objectives

To develop and validate the Oxford Needle Experience (ONE) scale, an instrument to assess needle fear, attitudes and expectations in the general population.

Design

Cross-sectional validation study.

Setting

Internet-based with participants in the UK and USA.

Participants

UK and US representative samples stratified by age, sex, and ethnicity using the Prolific Academic platform.

Main outcome measures

Exploratory factor analysis with categorical variables and a polychoric correlation matrix followed by promax oblique rotation on the UK sample for the ONE scale. Confirmatory factor analysis (CFA) with a Satorra-Bentler scaled test statistic evaluating the root mean squared error of approximation (RMSEA), standardised root mean squared residual (SRMR) and comparative fit index (CFI) on the US sample. Reliability as internal consistency using McDonald’s omega. Convergent validity using the Pearson correlation coefficient. Predictive and discriminant validity using logistic regression ORs of association (OR).

Results

The population included 1000 respondents, 500 in the UK and 500 in the USA. Minimum average partial correlation and a scree plot suggested four factors should be retained: injection hesitancy, blood-related hesitancy, recalled negative experiences and perceived benefits, yielding a 19-question scale. On CFA, the RMSEA was 0.070 (90% CI, 0.064 to 0.077), SRMR 0.053 and CFI 0.925. McDonald’s omega was 0.92 and 0.93 in the UK and US samples, respectively. Convergent validity with the four-item Oxford Coronavirus Explanations, Attitudes and Narratives Survey (OCEANS) needle fear scale demonstrated a strong correlation (r=0.83). Predictive validity with a single-question COVID-19 vaccination status question demonstrated a strong association, OR (95% CI) 0.97 (0.96 to 0.98), p

Conclusions

The ONE scale is a reliable and valid multidimensional scale that may be useful in predicting vaccine hesitancy, designing public health interventions to improve vaccine uptake and exploring alternatives to needles for medical procedures.

Influence of horizontal resistance loads on spatiotemporal and ground reaction force variables during maximal sprint acceleration

by Norihide Sugisaki, Kai Kobayashi, Takaya Yoshimoto, Naotoshi Mitsukawa, Hiroyasu Tsuchie, Yohei Takai, Hiroaki Kanehisa

This study aimed to elucidate the influence of horizontal resistance loads on the spatiotemporal and ground reaction force (GRF) variables during maximal sprint acceleration. Nine male sprinters (20.2 ± 1.2 years; 175.3 ± 4.5 cm, 69.7 ± 6.1 kg) performed sprint-running with six loading conditions of one unresisted and five resisted loads of 4, 6, 8, 10, and 12 kg using a resistance training device with intelligent drag technology. During the trials, the GRFs for all steps were determined using a 50-m force plate system. The spatiotemporal and GRF variables at running velocity of every 0.5 m/s were obtained and compared across the loading conditions. The maximal running velocity under 0, 4, 6, 8, 10, and 12 kg loading conditions were 9.84 ± 0.41, 8.55 ± 0.41, 8.09 ± 0.33, 7.62 ± 0.34, 7.11 ± 0.31, and 6.71 ± 0.29 m/s, respectively. ANOVA revealed significant main effects of load on the measured variables (η2 = 0.236–0.715, p

Interventions to support nurses as second victims of patient safety incidents: A qualitative study of nurse managers' perceptions

Abstract

Aims

To describe nurse managers' perceptions of interventions to support nurses as second victims of patient safety incidents and to describe the management of interventions and ways to improve them.

Design

A qualitative study using interviews.

Methods

A purposive sample of nurse managers (n = 16) recruited from three hospital districts in Finland was interviewed in 2021. The data were analysed using elements of inductive and deductive content analysis.

Results

The study identified three main categories: (1) Management of second victim support, which contained three sub-categories related to the nurse manager's role, support received by the nurse manager and challenges of support management; (2) interventions to support second victims included existing interventions and operating models; and (3) improving second victim support, based on the sub-categories developing practices and developing an open and non-blaming patient safety culture.

Conclusion

Nurse managers play a crucial role in supporting nurses as second victims of patient safety incidents and coordinating additional support. Operating models for managing interventions could facilitate nurse managers' work and ensure adequate support for second victims. The support could be improved by increasing the awareness of the second victim phenomenon.

Implications for the Profession and Patient Care

Mitigating the harmful effects of patient safety incidents can improve nurses' well-being, reduce burden and attrition risks and positively impact patient safety.

Impact

Increasing awareness of the second victim phenomenon and coherent operation models would provide equal support for the nurses and facilitate nurse managers' work.

Reporting Method

COREQ checklist was used.

What does this paper contribute to the wider global clinical community? Nurse managers' role is significant in supporting the second victims and coordinating additional support. Awareness of the second victim phenomenon and coherent operating models can secure adequate support for the nurses and facilitate nurse managers' work.

Por: Rousham · E. · Pareja · R. G. · Creed-Kanashiro · H. M. · Bartolini · R. · Pradeilles · R. · Ortega-Roman · D. · Holdsworth · M. · Griffiths · P. · Verdezoto · N.
Introduction

Nutrition during the complementary feeding period (6–23 months) is critical to ensure optimal growth and reduce the risk of diet-related disease across the life course. Strategies to reduce multiple forms of malnutrition (stunting, overweight/obesity and anaemia) in infants and young children (IYC) are a key priority in low-income and middle-income countries, including Peru. This study aims to co-design and develop prototypes for interventions to address the multiple forms of malnutrition in IYC in urban Peru, using a participatory design approach.

Methods and analysis

The study will be based within peri-urban communities in two areas of Peru (Lima and Huánuco city). Following the identification of key nutritional challenges for IYC aged 6–23 months through formative research (phase I), we will conduct a series of workshops bringing together healthcare professionals from government health centres and caregivers of IYC aged 6–23 months. Workshops (on idea generation; creating future scenarios; storyboarding and early implementation and feedback) will take place in parallel in the two study areas. Through these workshops, we will engage with community participants to explore, experiment, co-design and iteratively validate new design ideas to address the challenges around IYC complementary feeding from phase I. Workshop outputs and transcripts will be analysed qualitatively using affinity diagramming and thematic analyses. The intervention prototypes will be evaluated qualitatively and piloted with the participating communities.

Ethics and dissemination

Ethical approval for this study was obtained from the Ethical Review Committee of the Instituto de Investigación Nutricional (IIN) Peru (388-2019/CIEI-IIN), Loughborough University (C19-87) and confirmed by Cardiff University. Findings of the participatory design process will be disseminated through a deliberative workshop in Lima, Peru with national and regional government stakeholders, as well as participants and researchers involved in the design process. Further dissemination will take place through policy briefs, conferences and academic publications.

Non-infectious diseases in infectious disease consultation: A descriptive study in a tertiary care teaching hospital

by Yoshiro Hadano, Takanori Matsumoto

In this retrospective study, we aimed to investigate the frequency, trend, and nature of non-infectious diseases (non-IDs) as the final diagnosis for patients during an infectious disease (ID) consultation in an acute care hospital in Japan. This study included adult inpatients who underwent ID consultations between October 2016 and March 2018. The demographic data, clinical manifestations, and final non-ID diagnoses of cases were explored. Among the 502 patients who underwent ID consultations, 45 (9.0%) were diagnosed with non-IDs. The most common diagnoses were tumors (22.2%, n = 10), connective tissue and collagen vascular diseases (13.3%, n = 6), other inflammatory diseases (8.9%, n = 4), and drug-induced fever (8.9%, n = 4). Multiple logistic regression analysis showed that the presence of consultations for diagnosis (odds ratio [OR], 22.0; 95% confidence interval [CI], 10.1–48.2; p

Measuring patients' experiences of continuity of care in a primary care context—Development and evaluation of a patient‐reported experience measure

Abstract

Background

Continuity of care is viewed as a hallmark of high-quality care in the primary care context. Measures to evaluate the quality of provider performance are scarce, and it is unclear how the assessments correlate with patients' experiences of care as coherent and interconnected over time, consistent with their preferences and care needs.

Aim

To develop and evaluate a patient-reported experience measure of continuity of care in primary care for patients with complex care needs.

Method

The study was conducted in two stages: (1) development of the instrument based on theory and empirical studies and reviewed for content validity (16 patients with complex care needs and 8 experts) and (2) psychometric evaluation regarding factor structure, test–retest reliability, internal consistency reliability, and convergent validity. In all, 324 patients participated in the psychometric evaluation.

Results

The Patient Experienced Continuity of care Questionnaire (PECQ) contains 20 items clustered in four dimensions of continuity of care measuring Information (four items), Relation (six items), Management (five items), and Knowledge (five items). Overall, the hypothesized factor structure was indicated. The PECQ also showed satisfactory convergent validity, internal consistency, and stability.

Conclusion/Implications

The PECQ is a multidimensional patient experience instrument that can provide information on various dimensions useful for driving quality improvement strategies in the primary care context for patients with complex care needs.

Patient or Public Contribution

Patients have participated in the content validation of the items.

What are best practices for involving family caregivers in interventions aimed at responsive behaviour stemming from unmet needs of people with dementia in nursing homes: a scoping review

Objectives

This study aimed to determine best practices for involving family caregivers in interventions aimed at preventing and reducing responsive behaviour stemming from unmet needs, including pain.

Design

Scoping review, reported according to the Preferred Reporting Items for Systematic Reviews, Meta-Analyses extension for Scoping Reviews reporting guideline.

Data sources

PubMed, Embase, Emcare, Web of Science, COCHRANE Library, PsycINFO, Academic Search Premier and Cinahl searched up to 23 July 2023.

Eligibility criteria

Studies reporting on family involvement in interventions for nursing home residents with dementia were included.

Data extraction and synthesis

Two researchers independently extracted the data, followed by a content analysis.

Results

Of the 1486 records screened, 20 studies were included. Family caregivers were involved in interventions aimed at planning care, life review (eg, documentation of life experiences of their relative), and selecting activities for their relative. Family caregivers preferred an active role in developing optimal care for their relative. Drivers of success and barriers to family involvement centred around three themes: (1) communication between all involved; (2) prerequisites (organisational and other conditions) and (3) personal circumstances (family’s coping and skills).

Conclusion

Best practices for involving family caregivers in interventions aimed at addressing responsive behaviour in residents with dementia concerned those interventions in which family caregivers were given an important role in managing responsive behaviour. This means that, in order to achieve an active role of family caregivers in the whole care process, their needs must be taken into account.

Automated, high-throughput quantification of EGFP-expressing neutrophils in zebrafish by machine learning and a highly-parallelized microscope

by John Efromson, Giuliano Ferrero, Aurélien Bègue, Thomas Jedidiah Jenks Doman, Clay Dugo, Andi Barker, Veton Saliu, Paul Reamey, Kanghyun Kim, Mark Harfouche, Jeffrey A. Yoder

Normal development of the immune system is essential for overall health and disease resistance. Bony fish, such as the zebrafish (Danio rerio), possess all the major immune cell lineages as mammals and can be employed to model human host response to immune challenge. Zebrafish neutrophils, for example, are present in the transparent larvae as early as 48 hours post fertilization and have been examined in numerous infection and immunotoxicology reports. One significant advantage of the zebrafish model is the ability to affordably generate high numbers of individual larvae that can be arrayed in multi-well plates for high throughput genetic and chemical exposure screens. However, traditional workflows for imaging individual larvae have been limited to low-throughput studies using traditional microscopes and manual analyses. Using a newly developed, parallelized microscope, the Multi-Camera Array Microscope (MCAM™), we have optimized a rapid, high-resolution algorithmic method to count fluorescently labeled cells in zebrafish larvae in vivo. Using transgenic zebrafish larvae, in which neutrophils express EGFP, we captured 18 gigapixels of images across a full 96-well plate, in 75 seconds, and processed the resulting datastream, counting individual fluorescent neutrophils in all individual larvae in 5 minutes. This automation is facilitated by a machine learning segmentation algorithm that defines the most in-focus view of each larva in each well after which pixel intensity thresholding and blob detection are employed to locate and count fluorescent cells. We validated this method by comparing algorithmic neutrophil counts to manual counts in larvae subjected to changes in neutrophil numbers, demonstrating the utility of this approach for high-throughput genetic and chemical screens where a change in neutrophil number is an endpoint metric. Using the MCAM™ we have been able to, within minutes, acquire both enough data to create an automated algorithm and execute a biological experiment with statistical significance. Finally, we present this open-source software package which allows the user to train and evaluate a custom machine learning segmentation model and use it to localize zebrafish and analyze cell counts within the segmented region of interest. This software can be modified as needed for studies involving other zebrafish cell lineages using different transgenic reporter lines and can also be adapted for studies using other amenable model species.

Cardiac response to water activities in children with Long QT syndrome type 1

by Anna Lundström, Urban Wiklund, Annika Winbo, Håkan Eliasson, Marcus Karlsson, Annika Rydberg

Background

Swimming is a genotype-specific trigger in long QT syndrome type 1 (LQT1).

Objective

To examine the autonomic response to water activities in children and adolescents with LQT1.

Methods

In this cross-sectional study, LQT1 patients were age and sex matched to one healthy control subject. Electrocardiograms (ECGs) were recorded during face immersion (FI), swimming, diving, and whole-body submersion (WBS). Heart rate (HR) and heart rate variability (HRV) was measured. The high frequency (HF) component of HRV was interpreted to reflect parasympathetic activity, while the low frequency (LF) component was interpreted as reflecting the combined influence of sympathetic and parasympathetic activity on autonomic nervous modulation of the heart.

Results

Fifteen LQT1 patients (aged 7–19 years, all on beta-blocker therapy) and fifteen age and sex matched non-medicated controls were included. No significant ventricular arrhythmias were observed in the LQT1 population during the water activities. Out of these 15 matched pairs, 12 pairs managed to complete FI and WBS for more than 10 seconds and were subsequently included in HR and HRV analyses. In response to FI, the LQT1 group experienced a drop in HR of 48 bpm, compared to 67 bpm in the control group (p = 0.006). In response to WBS, HR decreased by 48 bpm in the LQT1 group and 70 bpm in the control group (p = 0.007). A significantly lower PTOT (p Conclusion

A significantly lower HR decrease in response to water activities was observed in LQT1 subjects on beta-blocker therapy, compared to matched non-medicated controls. The data suggests an impaired parasympathetic response in LQT1 children and adolescents. An aberrant autonomic nervous system (ANS) response may cause an autonomic imbalance in this patient group.

Radiographers’ perceptions on the quality of managing general radiographic paediatric examinations through the use of a reflective tool

by Kate Caruana, Chris Hayre, Chandra Makanjee

Introduction

Paediatric patients are a vulnerable population that require additional care by healthcare professionals. Quality managing these examinations ensures that effective and quality care is provided to individual patients, whilst encouraging consistency within the medical imaging department. This study explored radiographers’ perspectives on quality management strategies of general radiographic paediatric examinations using a paediatric imaging reflective checklist.

Methods

A quantitative descriptive research design with qualitative questions was used through a purposive sampling method from both public and private Australian diagnostic imaging qualified radiographers who had experience in paediatric imaging examinations. The paediatric imaging service reflective tool consisted of 65 items in total. Data analysis entailed Microsoft Excel version 16.16.6 and Jamovi version 2.3.21 for the closed-ended questions and for the open-ended responses a thematic analysis.

Results

The participation rate was 13.2% and the most significant findings were: lead shielding was still being used at their organisation, despite recent recommendations to suspend its use; access to paediatric patient related information resources is limited; there was no involvement of families and communities regarding policy development or quality improvement measures as advocated in literature; and there was a need for enhanced specialised paediatric education, training and protocols.

Conclusion

Using the paediatric patient-centred imaging reflective checklist, radiographers had an opportunity to identify quality improvement indicators as well as issues that could further enhance best practice principles. Further studies could inform on the validity of this reflective tool.

The association between cardiopulmonary exercise testing and postoperative outcomes in patients with lung cancer undergoing lung resection surgery: A systematic review and meta-analysis

by Nabeela Arbee-Kalidas, Hlamatsi Jacob Moutlana, Yoshan Moodley, Moses Mogakolodi Kebalepile, Palesa Motshabi Chakane

Background

Exercise capacity should be determined in all patients undergoing lung resection for lung cancer surgery and cardiopulmonary exercise testing (CPET) remains the gold standard. The purpose of this study was to investigate associations between preoperative CPET and postoperative outcomes in patients undergoing lung resection surgery for lung cancer through a review of the existing literature.

Methods

A search was conducted on PubMed, Scopus, Cochrane Library and CINAHL from inception until December 2022. Studies investigating associations between preoperative CPET and postoperative outcomes were included. Risk of bias was assessed using the QUIPS tool. A random effect model meta-analysis was performed. I2 > 40% indicated a high level of heterogeneity.

Results

Thirty-seven studies were included with 6450 patients. Twenty-eight studies had low risk of bias. V˙O2 peak is the oxygen consumption at peak exercise and serves as a marker of cardiopulmonary fitness. Higher estimates of V˙O2 peak, measured and as a percentagege of predicted, showed significant associations with a lower risk of mortality [MD: 3.66, 95% CI: 0.88; 6.43 and MD: 16.49, 95% CI: 6.92; 26.07] and fewer complications [MD: 2.06, 95% CI: 1.12; 3.00 and MD: 9.82, 95% CI: 5.88; 13.76]. Using a previously defined cutoff value of > 15mL/kg/min for V˙O2 peak, showed evidence of decreased odds of mortality [OR: 0.55, 95% CI: 0.28–0.81] and but not decreased odds of postoperative morbidity [OR: 0.82, 95% CI: 0.64–1.00]. There was no relationship between V˙E/V˙CO2 slope, which depicts ventilatory efficiency, with mortality [MD: -9.60, 95% CI: -27.74; 8.54] however, patients without postoperative complications had a lower preoperative V˙E/V˙CO2 [MD: -2.36, 95% CI: -3.01; -1.71]. Exercise load and anaerobic threshold did not correlate with morbidity or mortality. There was significant heterogeneity between studies.

Conclusions

Estimates of cardiopulmonary fitness as evidenced by higher V˙O2 peak, measured and as a percentage of predicted, were associated with decreased morbidity and mortality. A cutoff value of V˙O2 peak > 15mL/kg/min was consistent with improved survival but not with fewer complications. Ventilatory efficiency was associated with decreased postoperative morbidity but not with improved survival. The heterogeneity in literature could be remedied with large scale, prospective, blinded, standardised research to improve preoperative risk stratification in patients with lung cancer scheduled for lung resection surgery.

Introduction

Relative to outdoor air pollution, there is little evidence examining the composition and concentrations of indoor air pollution and its associated health impacts. The INGENIOUS project aims to provide the comprehensive understanding of indoor air pollution in UK homes.

Methods and analysis

‘Real Home Assessment’ is a cross-sectional, multimethod study within INGENIOUS. This study monitors indoor air pollutants over 2 weeks using low-cost sensors placed in three rooms in 300 Born in Bradford (BiB) households. Building audits are completed by researchers, and participants are asked to complete a home survey and a health and behaviour questionnaire, in addition to recording household activities and health symptoms on at least 1 weekday and 1 weekend day. A subsample of 150 households will receive more intensive measurements of volatile organic compound and particulate matter for 3 days. Qualitative interviews conducted with 30 participants will identify key barriers and enablers of effective ventilation practices. Outdoor air pollution is measured in 14 locations across Bradford to explore relationships between indoor and outdoor air quality. Data will be analysed to explore total concentrations of indoor air pollutants, how these vary with building characteristics, and whether they are related to health symptoms. Interviews will be analysed through content and thematic analysis.

Ethics and dissemination

Ethical approval has been obtained from the NHS Health Research Authority Yorkshire and the Humber (Bradford Leeds) Research Ethics Committee (22/YH/0288). We will disseminate findings using our websites, social media, publications and conferences. Data will be open access through the BiB, the Open Science Framework and the UK Data Service.

Application of Skyline software for detecting prohibited substances in doping control analysis

by Hyeon-Jeong Lee, Mijin Jeon, Yoondam Seo, Inseon Kang, Wooyeon Jeong, Junghyun Son, Eugene C. Yi, Hophil Min

As the number of prohibited drugs has been progressively increasing and analytical methods for detecting such substances are renewed continuously for doping control, the need for more sensitive and accurate doping analysis has increased. To address the urgent need for high throughput and accurate analysis, liquid chromatography with tandem mass spectrometry is actively utilized in case of most of the newly designated prohibited substances. However, because all mass spectrometer vendors provide data processing software that is incapable of handling other instrumental data, it is difficult to cover all doping analysis procedures, from method development to result reporting, on one platform. Skyline is an open-source and vendor-neutral software program invented for the method development and data processing of targeted proteomics. Recently, the utilization of Skyline has been expanding for the quantitative analysis of small molecules and lipids. Herein, we demonstrated Skyline as a simple platform for unifying overall doping control, including the optimization of analytical methods, monitoring of data quality, discovery of suspected doping samples, and validation of analytical methods for detecting newly prohibited substances. For method optimization, we selected the optimal collision energies for 339 prohibited substances. Notably, 195 substances exhibited a signal intensity increase of >110% compared with the signal intensity of the original collision energy. All data related to method validation and quantitative analysis were efficiently visualized, extracted, or calculated using Skyline. Moreover, a comparison of the time consumed and the number of suspicious samples screened in the initial test procedure highlighted the advantages of using Skyline over the commercially available software TraceFinder in doping control.

The effect of a brinzolamide/brimonidine fixed combination on optic nerve head blood flow in rabbits

by Nana Takahashi, Kota Sato, Naoki Kiyota, Mai Yamazaki, Eriko Kunikane, Toru Nakazawa

Purpose

The purpose of this study was to investigate the effect of a 1% brinzolamide and 0.1% brimonidine fixed combination (BBFC) on ONH blood flow (BF) in rabbits.

Methods

A crossover study was conducted on pigmented rabbits; a physiological saline solution, brinzolamide, or BBFC was administered for eight days. ONH BF, intraocular pressure (IOP) and systemic parameters were measured before the eighth day’s first dose and at 6, 9, 12, and 14 hours after the dose. ONH BF was assessed using laser speckle flowgraphy, and mean blur rate (MBR) values were calculated. The percentage against baseline of each parameter was calculated, and intergroup comparisons were performed at each time point.

Results

There were no significant differences in the percentage change in systemic parameters. At 6 hours after administration, the BBFC group showed a significantly higher percentage change in large vessel area-MBR (%MV) compared to the control group (98.6±16.8%MV vs. 81.3±7.9%MV, P = 0.03). On the other hand, the brinzolamide group did not show a significant difference. Both the brinzolamide and BBFC groups had significantly lower percentage change in IOP (%IOP) compared to the control group (90.6±5.0%IOP, 93.3±2.9%IOP, and 99.2±1.7%IOP, respectively, P Conclusion

BBFC effectively reduces IOP and mitigates diurnal fluctuation-induced decreases in ONH BF.

A Semantic Segment Encoder (SSE): Improving human face inversion quality through minimized learning space

by Byungseok Kang, Youngjae Jo

Recently, Generative Adversarial Networks (GAN) has been greatly developed and widely used in image synthesis. A Style-Based Generator Architecture for Generative Adversarial Networks (StyleGAN) which is the foremost, continues to develop human face inversion domain. StyleGAN uses insufficient vector space to express more than one million pixels. It is difficult to apply in real business due to distortion-edit tradeoff problem in latent space. To overcome this, we propose a novel semantic segment encoder (SSE) with improved face inversion quality by narrowing the size of restoration latent space. Encoder’s learning area is minimized to logical semantic-segment units that can be recognized by humans. The proposed encoder does not affect other segments because only one segment is edited at a time. To verify the face inversion quality, we compared with the latest encoders both Pixel2style2Pixel and RestyleEncoder. Experimental result shows that the proposed encoder improved distortion quality around 20% while maintain editing performance.

Researcher‐initiated role play, stimulated recall interview, storycrafting, painting and drawing as research methods to reach children's perspectives in health sciences

Abstract

Aim

To describe the application of selected creative and participatory research methods in nursing science.

Design

Research methodology paper.

Methods

Researcher-initiated role play, stimulated recall interviews, the Storycrafting method, painting and drawing. Altogether, 11 children (5–7 years old) and 12 parents participated in the research.

Results

Each small group (n = 3) acted differently during the data collection. Not every child wanted to play, draw or tell stories, but they all expressed their views through some method. Although the same themes emerged from children's narratives, they could not have been verified by just one method.

Conclusions

Using creative and participatory methods and the principles of studies of child perspectives are applicable ways of conducting research in nursing science. Children must be treated as individuals during the research process, and they must have opportunities to use several communication methods to express their views.

Implications for the profession and patient care

Understanding different ways to interact with children and hear children's views will help nurses to encounter children.

Impact

In this article, we present a valid way of conducting research with children. By following our protocol, nursing research from a child perspective can be implemented.

Reporting Method

Consolidated criteria for reporting qualitative research (COREQ).

Patient Contribution

The child participants were involved in choosing physical places for data collection and the usage and order of the selected methods. Both the children and the adult participants took part in interpreting the research data.

Abstract

Aim

To identify evidence on frontline nurse leaders' competences in evidence-based healthcare (EBHC) and the instruments measuring these competences.

Design

A scoping review.

Data Sources

The search was conducted in June 2021 and complemented in June 2022. The CINAHL, ProQuest, Medline (Ovid), Scopus, Web of Science databases and MedNar along with the Finnish database Medic were searched.

Review Method

The scoping review was conducted in accordance with the Joanna Briggs institute methodology for scoping reviews. Titles, abstracts and full-text versions were screened independently by two reviewers according to the inclusion criteria. Deductive-inductive content analysis was used to synthesize data.

Results

A total of 3211 articles published between 1997 and 2022 were screened, which resulted in the inclusion of 16 articles. Although frontline nurse leaders had a positive attitude towards EBHC, they had a lack of implementing EBHC competence into practice. Part of the instruments were used in the studies, and only one focused especially on leaders. None of instruments systematically covered all segments of EBHC.

Conclusion

There is a limited understanding of frontline nurse leaders' competence in EBHC. It is important to understand the importance of EBHC in healthcare and invest in the development of its competence at all levels of leaders. Frontline nurse leaders' support is essential for direct care nurses to use EBHC to ensure the quality of care and benefits to patients. Leaders must enhance their own EBHC competence to become role models for direct care nurses. It is also essential to develop valid and reliable instruments to measure leaders' competence covering all EBHC segments. The results can be utilized in the assessment and development of frontline nurse leaders' EBHC competence by planning and producing education and other competence development methods.

Understanding medication-related burden from patient perspectives: a qualitative study testing the applicability of the conceptual model among chronically ill outpatients in Finland

Objectives

Disease self-management and medication therapy can cause burden to patients that can influence adherence. The conceptual model ‘patients’ lived experience with medicine’ (PLEM) brings new insights into medication-related burden (MRB) from patient perspective. This study aimed to test the applicability of the PLEM model by interviewing chronically ill patients in Finland and to investigate the MRB experienced by the Finnish patients.

Design

Focus group discussion study conducted online via Zoom. Directed qualitative content analysis guided by the PLEM model.

Setting

Outpatient primary care in Finland.

Participants

Chronically ill outpatients (n=14) divided into five focus groups according to their chronic condition: asthma (n=3), heart disease (n=3), diabetes (n=6), intestinal disease (n=2).

Results

Our findings were mainly in line with the PLEM model although some new contributing factors to MRB emerged. In general, the participants were satisfied with their medication, and that it enabled them to live normal lives. The most common causes of MRB were medication routines and the healthcare system. The participants introduced two new aspects contributing to MRB: medication-related environmental anxiety associated with the waste resulting from medicine use, and the effect of medication use on their working life. Our findings are consistent with previous findings that a higher level of MRB may lead to independently modifying the medication regimen or not taking the medicine.

Conclusions

Our findings provide further evidence that the PLEM model is an applicable tool also in the Finnish context for gaining better understanding of MRB in chronically ill patients self-managing their long-term medications. The model provides a promising tool to understand the connection between MRB and the rationale for not always taking medicines as prescribed. Further research is needed to explore the potential of the model in extending patient perspectives in chronic disease management.
