Impact of signal-to-noise ratio and contrast definition on the sensitivity assessment and benchmarking of fluorescence molecular imaging systems.

Significance: Standardization of fluorescence molecular imaging (FMI) is critical for ensuring quality control in guiding surgical procedures. To accurately evaluate system performance, two metrics, the signal-to-noise ratio (SNR) and contrast, are widely employed. However, there is currently no consensus on how these metrics can be computed. Aim: We aim to examine the impact of SNR and contrast definitions on the performance assessment of FMI systems. Approach: We quantified the SNR and contrast of six near-infrared FMI systems by imaging a multi-parametric phantom. Based on approaches commonly used in the literature, we quantified seven SNRs and four contrast values considering different background regions and/or formulas. Then, we calculated benchmarking (BM) scores and respective rank values for each system. Results: We show that the performance assessment of an FMI system changes depending on the background locations and the applied quantification method. For a single system, the different metrics can vary up to ∼ 35 dB (SNR), ∼ 8.65 a . u . (contrast), and ∼ 0.67 a . u . (BM score). Conclusions: The definition of precise guidelines for FMI performance assessment is imperative to ensure successful clinical translation of the technology. Such guidelines can also enable quality control for the already clinically approved indocyanine green-based fluorescence image-guided surgery.

Pediatric reference values of NT-proBNP and Galectin-3 based on a French cohort.

BACKGROUND: In pediatric cardiology, the fact that some new biomarkers have assay-specific normal values has to be considered for correct clinical decisions. The current study aimed to provide age-adjusted normative values for NT-proBNP and Galectin-3 using the Abbott immunoassay system from a prospective French pediatric cohort sera collection and to validate our data for NT-proBNP on a second retrospective cohort. METHODS: We analyzed 283 consecutive samples for NT-proBNP and 140 samples for Galectin-3 collected from apparently healthy children (0-18 years) with outpatient treatment at our institution (Hôpital Necker-Enfants malades, Paris, France) during 24 months. RESULTS: For NT-proBNP and Galectin-3, we establish four age partitions, respectively two (<2 years / >2 years) and establish upper reference values and their 90 % CI for each biomarker (Galectin-3 (ng/mL): 56 [44-70] / 26 [23-29]). We evaluated the diagnostic performance of our upper reference values of NT-proBNP on a retrospective cohort (n = 428) with positive predictive value of 0.92. CONCLUSIONS: Using Abbott immunoassay system, we report age-specific reference values for NT-proBNP and for the first time for Galectin-3 in a healthy French pediatric cohort. These data call for larger cohort studies to define more robustly percentiles and diagnostic performance for NT-proBNP.

A Comprehensive Guide to Quality Assessment and Data Submission for Genomic Surveillance of Enteric Pathogens.

This document outlines the steps necessary to assemble and submit the standard data package required for contributing to the global genomic surveillance of enteric pathogens. Although targeted to GenomeTrakr laboratories and collaborators, these protocols are broadly applicable for enteric pathogens collected for different purposes. There are five protocols included in this chapter: (1) quality control (QC) assessment for the genome sequence data, (2) validation for the contextual data, (3) data submission for the standard pathogen package or Pathogen Data Object Model (DOM) to the public repository, (4) viewing and querying data at NCBI, and (5) data curation for maintaining relevance of public data. The data are available through one of the International Nucleotide Sequence Database Consortium (INSDC) members, with the National Center for Biotechnology Information (NCBI) being the primary focus of this document. NCBI Pathogen Detection is a custom dashboard at NCBI that provides easy access to pathogen data plus results for a standard suite of automated cluster and genotyping analyses important for informing public health and regulatory decision-making.

Quality control for serological testing.

OBJECTIVES: The quality control of serological assays remains controversial. The aim of this project was to describe the problems associated with a working model for controlling these assays and solutions, including using a source of well-defined targets and acceptable limits, a process to identify lot-to-lot reagent variation and an interpretation of the result that accounted for the clinical situation. False-negative results are problematic but can be reduced by identifying and comparing reagent lot variation with previous results. METHODS: The components of the Quality Assurance strategy are the following: Lot-to-lot reagent and calibrator variation assessment; dynamic, big-data approach to determine accurate targets and acceptable limits for manufacturer-provided QC material; negative QC monitoring process; use of commutable EQA with a sufficient method subgroup size to assess bias; clinical assessment of any statistically flagged error; and provision of support to the clinician for the interpretation of results. RESULTS: The model described has been used for twelve months, and acceptable variation has been maintained. CONCLUSIONS: The paper presents a solution that emphasizes the early detection of reagent lot variation and patient risk rather than instrument control. Reducing the risk of a false result to patients requires optimal assay quality control and an effective mechanism to support the clinician's use of these results in diagnosis and monitoring. The problems of serological assays are well-known, but there remain few integrated solutions in the literature.

[Cross-cultural adaptation and reliability of the Argentine version of the trunk control test in subjects with sequelae of spinal cord injury] / Adaptación transcultural y fiabilidad del trunk control test versión argentina en sujetos con secuela de lesión medular espinal.

Background: spinal cord injury leaves as a sequel in the acute and chronic period, deficiencies in the stability of joint functions and in the function of voluntary movement control. Those with good trunk control have a greater probability of carrying out activities of daily living by themselves; up to now, we do not have reliable tools in Argentina that evaluate trunk control in these subjects. Objectives: to cross-culturally adapt the trunk control test to Argentinean Spanish in subjects with sequelae of spinal cord injury and to establish interobserver and intraobserver reliability. Methodology: the subjects were admitted using a non-probabilistic convenience sampling. Subjects who were between 15 and 75 years old and had a diagnosis of spinal cord injury were included. Subjects who had: another neurological diagnosis, alteration in sensory organs, conditions that prevent the performance of the test, and psychiatric illness were excluded. Results: 30 subjects were included for cross-cultural adaptation and 55 for reliability. Semantic modifications were made to all items and response options. The intraobserver and interobserver reliability of the scale or subdomains did not achieve a sufficient score. Conclusion: the trunk control test was adapted cross-culturally to Argentine Spanish and interobserver and intraobserver reliability was established. The adaptation was achieved through semantic changes and the reliability was not sufficient. In the future, studies should be carried out to improve the reliability and study the validity of the tool.

Introducción: la lesión de la médula espinal deja como secuela en el período agudo y crónico, deficiencias en la estabilidad de las funciones articulares y de la función del control de los movimientos voluntarios. Aquellos con buen control de tronco poseen una mayor probabilidad de realizar por sí mismos  actividades de la vida diaria, hasta el momento, no contamos en Argentina con herramientas fiables  que evalúen el control de tronco en estos sujetos. Objetivos: adaptar transculturalmente al castellano argentino el trunk control test  en sujetos con secuela de lesión medular espinal y establecer la fiabilidad interobservador, intraobservador. Metodología: los sujetos fueron ingresados mediante un muestreo no probabilístico  por conveniencia. Se incluyeron sujetos que: posean entre 15 años a 75 años y tengan diagnóstico de lesión medular espinal, se excluyeron sujetos que posean: otro diagnóstico neurológico, alteración en los órganos sensoriales, condiciones que impidan la realización de la prueba y enfermedad psiquiátrica. Resultados: 30 sujetos fueron incluidos para la adaptación transcultural y 55 para la fiabilidad. Se realizaron modificaciones semánticas en todos los ítems y opciones de respuesta.

Conclusión:  se adaptó transculturalmente al castellano argentino el trunk control test y se estableció la fiabilidad interobservador, intraobservador. La adaptación se logró a través de cambios semánticos y la fiabilidad no fue suficiente. A futuro se deberán realizar estudios para mejorar la fiabilidad y estudiar la validez de la herramienta.

Critical soft skill competencies that clinical nurse educators consider important to evaluate in nurses.

AIM: Guided by Benner's framework, From Novice to Expert, this study aimed to identify (1) critical soft skills to be evaluated in nurses and (2) levels of nursing behaviour indicating achievement of soft skills to provide a framework for developing a soft skills rubric. BACKGROUND/INTRODUCTION: Nurse shortages are often attributable to high turnover rates among nurses. To improve this situation, healthcare facilities implement transition programmes and continuing education with a primary focus on developing and maintaining nurses' knowledge and performance (hard skills). However, balancing hard and soft skills (beliefs, values and attitudes) is key to nurses' quality of care and ultimately to their retention. Despite the importance of soft skills, their intangible nature creates problems in evaluating nurses' attainment of these skills and in providing constructive feedback to help them set concrete goals for improving their practice. METHODS: This qualitative descriptive study described critical soft skills in the nursing context. A purposeful sampling strategy was used to enrol 13 clinical nurse educators from multiple hospital units; each had more than 2 years of clinical nurse educator experience and had completed preceptor training. One-to-one interviews with these individuals were audio recorded, transcribed and subjected to direct content analysis using NVivo 12. The study follows the Consolidated criteria for reporting qualitative research (COREQ) guidelines for qualitative studies. FINDINGS: Five main competencies, comprising 20 subcompetencies, were identified: personal growth, effective interactions, professionalism, teamwork and the caring role. For each subcompetency, four skill levels were delineated using clinical indicators. CONCLUSION: This study's findings can enhance understanding of clinical nurse educators' perceptions regarding soft skills required of nurses. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The soft skills identified can be incorporated into a rubric to be used by clinical nurse educators to evaluate and guide nurses' professional development and contribute to improving quality of care. No patient or public contribution is required for this study.

Patient Engagement in a Mobile App-Based Rehabilitation Program for Total Hip or Knee Arthroplasty: Secondary Data Analysis of a Randomized Controlled Trial.

BACKGROUND: Health care professionals use mobile apps to support patients' rehabilitation after total hip or knee arthroplasty. Understanding patient engagement in such mobile health interventions can help tailor these interventions to better support patients. OBJECTIVE: This study aimed to investigate patient engagement in a mobile app-based arthroplasty rehabilitation program and to investigate the association between patient engagement and their characteristics. METHODS: Data were extracted from a pool of 42 participants in the experimental arm of a randomized controlled trial that used a mobile app (WeChat [Tencent Holdings Limited])-based program to support patients' rehabilitation after total hip or knee arthroplasty. The primary outcomes were the number of days the participants accessed the program and completed recommended rehabilitation tasks. Secondary outcomes included data on the participants' posts on a discussion forum, messages sent by the participants, access to the program components, and reading and sharing the program content. Generalized linear models were used to analyze the association between patient engagement and personal characteristics. RESULTS: The participants reported in a rehabilitation diary accessing the program on a mean of 5.2 (SD 2) days per week and completing recommended rehabilitation tasks on a mean of 6.5 (SD 0.8) days per week. The majority (31/42, 74%) posted on the discussion forum, with a mean of 18.1 (SD 21.2) posts. Most participants (37/42, 88%) sent messages to health care professionals, with a mean of 14 (SD 15.9) messages. The program components were visited for a total of 525 times. The program content was read 898 times and shared 82 times in total. Generalized linear models showed that both primary outcomes, the number of days the participants accessed the program (B=6.46, 95% CI 1.98-15.35; χ21=11.1, P=.001) and the number of days they completed rehabilitation tasks (B=2.65, 95% CI 0.45-5.48; χ21=5.7, P=.02), were positively associated with having a high school education or above. In addition, the number of posts on the discussion forum was positively associated with living with family, having a high school education or above, undergoing total knee arthroplasty, having comorbidities, and the score of self-efficacy but was negatively associated with age. The number of messages sent by the participants was positively associated with having a high school education or above, having comorbidities, and the score of self-efficacy. CONCLUSIONS: Patient engagement in mobile arthroplasty rehabilitation is associated with their education level, cohabitation status, age, type of surgery, presence of comorbidities, and sense of self-efficacy. Program developers can consider these characteristics and use strategies, such as family involvement, in the design of mobile arthroplasty rehabilitation programs to enhance patient engagement in such interventions.

Exploring the Utility of a Novel Approach of Evaluating Application of a Validated Violence Risk Assessment Instrument.

Mental health nurses are often responsible for assessment/management of inpatient aggression. Validated instruments such as the Dynamic Appraisal of Situational Aggression (DASA), can aid risk assessment. However, limited attention has been paid to evaluating nurses' ability to administer risk assessment instruments. An entrustable professional activity may offer way of evaluating risk assessment clinical activities. DASA trainers' perceptions of the value and utility of an EPA were explored via collection of data through focus groups, with 17 participants from six countries. Thematic analysis was conducted to analyze the data. Three themes were interpreted: (1) DASA trainers-a way of knowing and being (2) An EPA-something you did not know you need until you see it; (3) The DASA-EPA supports the need for training and importance of integrity in assessment. Trainers engaged in innovative ways to ensure training is suitable and responsive to needs of nurses and their setting. Participants understood how an EPA could be used to evaluate DASA administration, monitor DASA use, provide feedback, and highlight the importance of training to ensure best practice.

Respectful Maternity Care during labour and postpartum in a tertiary hospital: A Descriptive Cross-sectional Study.

INTRODUCTION: Respectful maternity care (RMC) is a fundamental human right for women globally. Providing respectful care during labor and postpartum is crucial for the health and well-being of both mothers and newborns. The interactions between healthcare providers and women play a significant role in shaping their future healthcare decisions. Therefore, this research aims to evaluate the prevalence of RMC during labor and postpartum from the patient's perspective at a tertiary care center. METHODS: We conducted a descriptive cross-sectional study at a tertiary center from February 20, 2023, to September 30, 2023. Ethical approval was obtained from the Institutional Review Committee of the same institution. A total of 217 patients were included using consecutive sampling techniques. Data were collected through interviews using a structured questionnaire on respectful maternity care. The point estimate was calculated with a 95% Confidence Interval. RESULTS: The prevalence of overall respectful maternity care (RMC) score was 81%. The score for right to confidentiality and privacy during labor was 91.7%, treated with dignity and respect was 90.87%, received equitable care free of discrimination was 86.41%, protection from physical harm and ill treatment was 84.02%, while protection of right to information/informed consent and choice'preference was 72.55%. CONCLUSIONS: This study demonstrated a high prevalence of respectful maternity care, with most patients experiencing protection of confidentiality, dignity, equitable treatment, safety, and informed consent, indicating effective implementation of RMC practices at our tertiary care center.\ Keywords: labour; maternity care; postpartum; prevalence; tertiary hospital.

Cross-cultural adaptation of the eHealth Literacy Scale for Brazilian adolescents.

The aim of this study was to undertake a cross-cultural adaptation of the eHealth Literacy Scale (eHEALS) instrument to measure digital health literacy of Brazilian adolescents. eHEALS is a scale consisting of 8 items that measure self-perception related to the consumption of electronic health information. This is a methodological study of cross-cultural adaptation, conducted out from February 2022 to June 2022. The following steps were carried out: a) assessment and adequacy of cultural equivalence by a committee of experts; b) back-translation; c) synthesis of back-translations; d) cognitive testing with 42 Brazilian adolescents, using cognitive interviews with probing questions. All items that were difficult to understand were adapted to the (language) context of Brazilian adolescents. Cronbach's alpha coefficient for eHEALS-BrA was 0.81 and, if one of the items were excluded from the instrument, it ranged from 0.75-0.81. This version of the eHEALS proved to be culturally well-adapted to the context of Brazilian adolescents, and has the potential to measure digital health literacy in this population after having its validation confirmed through psychometric analyses.

Feasibility and Engagement of a Mobile App Preparation Program (Kwit) for Smoking Cessation in an Ecological Context: Quantitative Study.

BACKGROUND: Mobile health apps can facilitate access to effective treatment and therapeutic information services. However, the real-world effectiveness of mobile apps for smoking cessation and their potential impact in everyday settings remain unclear. OBJECTIVE: In an ecological context, this study aimed to estimate the engagement rate of a mobile app-based smoking cessation preparation program and its potential impact on users' willingness, ability, and readiness to quit smoking. METHODS: A total of 2331 "organic users" (ie, users who discover and install a mobile app on their own, without any prompts) chose 1 of 2 program versions of the mobile app (Kwit): the basic version or the premium version. Both versions were identical in design, with 4 more evidence-based content items and strategies in the premium version. Outcomes were analyzed based on automated data registered in the app (engagement rate, motivation to quit, motivation type, motivation levels, and satisfaction level). Mann-Whitney and χ2 tests were used to compare the results of both groups. RESULTS: As expected, in the ecological context, a high dropout rate was observed at different moments. A significant difference was observed between the 2 versions (n=2331; χ21=5.4; P=.02), with a proportionally higher engagement rate in the premium version (premium=4.7% vs basic=2%). Likewise, differences were also observed between the 2 groups in terms of reasons to quit (n=2331; χ24=19; P≤.001; V=0.08), motivation type (n=2331; χ27=14.7; P=.04), and motivation level. Users of the app's premium version more frequently reported "well-being" (23.3% vs 17.9%) and "planning a pregnancy" (7.4% vs 4.4%) as their primary reasons for quitting smoking compared to those with the basic version. Moreover, they reported being more likely to be driven in the smoking cessation process by intrinsic motivation (premium=28% vs basic=20.4%), as well as feeling significantly more willing (z score=156,055; P≤.001; Cohen d=0.15), able (z score=172,905; P=.04; Cohen d=0.09), and ready (z score=166,390; P=.005; Cohen d=0.12) to stop smoking than users who had the basic version before completion of the preparation program. Among participants who finished each version of the program (premium: 9/189, 4.8%; basic: 47/2142, 2.19%), significant improvements in motivation levels were observed in both groups, although in different areas for each group (willingness levels for the premium group and ability for the basic group). CONCLUSIONS: These results suggest that even in ecological contexts where engagement rates are meager, the Kwit preparation program can address ambivalence by increasing willingness to change, self-confidence, and readiness to quit among its users, especially those who feel less able to do so. Further development and evaluations are needed to better understand determinants for regular mobile health apps.
