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.

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.

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.

Desirable clinical settings in general dentistry: moving towards the improvement of the educational program.

BACKGROUND: The main task of dental schools is to prepare professional dentists with a high social responsibility. This study provided some practical suggestions from experts regarding desirable clinical settings, in order to establish an infrastructure for practical studies in Endodontics, Periodontics, Oral and Maxillofacial Surgery, Restorative Dentistry, Pediatric Dentistry, Oral and Maxillofacial Medicine, Prosthodontics, Oral Health, and Social Dentistry. METHODS: This research was conducted using a modified Delphi technique in two rounds. The first round involved qualitative content analysis. Participants in interviews were selected purposeful and maximum diversity across the country. To determine the validity and reliability of the data, the four axes proposed by Lichon and Guba were utilized. The second round involved a researcher-made questionnaire, which consisted of 55 questions. This questionnaire was distributed to all dental schools across the country. The validity of the questionnaire were evaluated and by experts and then reviewed. The reliability of the tool was determined to be 0.96 using the alpha coefficient method. RESULTS: The final codes from the interviews of the first round were divided into two categories: settings and educational programs. The final results of research were placed into 2 section: educational settings and instructors, and educational infrastructures. 70% participants agreed to use the college's clinical morning sessions. More than 80% agreed to start up a main clinic with the proposed structure and professors. The use of the hospitalization area also had an agreement of more than 80%. Additionally, community areas such as health service centers, welfare centers, special patient centers, factories, schools, etc. obtained an agreement of over 70%. CONCLUSIONS: The results of this study are presented in the form of suggestions for improving the general dentistry program in relation to educational setting, educators, and educational infrastructures. The common agreement among participants regarding educational settings and their diversity, educational programs, and desired instructors reviewed in the research shows the necessity of reviewing and changing their educational programs in Endodontics, Periodontics, Oral and Maxillofacial Surgery, Restorative Dentistry, Pediatric Dentistry, Oral and Maxillofacial Medicine, Prosthodontics, Oral Health, and Social Dentistry.

Comparison of professional competency and anxiety of nursing students trained based on two internship models: a comparative study.

BACKGROUND: Improving the professional competency of nursing students during the internship is critical. This study aimed to compare the professional competency and anxiety of nursing students trained based on two internship models. METHODS: This is a two-group posttest-only quasi-experimental design study. One hundred nursing students who passed internship models A (a previous internship model) and B (an intervention with more educator support and a more planned and programmed process) were randomly enrolled in this study. Internship model groups A and B were conducted for the students in semesters 7 and 8. The outcomes assessed in both groups were "The Competency Inventory for Registered Nurses" and Spielberger "State-Trait Anxiety Inventory". T-test and MANOVA were used to analyze the data. RESULTS: The mean scores of competency were 134.56 (SD = 43.23) and 160.19 (SD = 35.81) for the nursing students in the internship model groups A and B, respectively. The mean scores of nursing students' anxiety were 92.14 (SD = 15.36) and 80.44 (SD = 18.16) in the internship model groups A and B, respectively. MANOVA test showed a significant difference between the groups regarding professional competency (F = 10.34, p = 0.002) and anxiety (F = 11.31, p = 0.001). CONCLUSIONS: The internship model group B could improve the professional competency of nursing students to a great extent and they experienced mild anxiety; it is suggested that this intervention should be done for nursing students. Conducting more studies to evaluate the effect of this model on the nursing students' competency and anxiety after graduation and as a novice nurse is suggested.

The effects of a quality improvement project to reduce caesarean sections in selected private hospitals in Brazil.

BACKGROUND: Brazil is one of the countries with the highest rates of caesarean sections (CS), reaching almost 90% of births in the private sector. A quality improvement project called "Adequate Childbirth Project (PPA)" was conceived to reduce CS in the private sector. This project consisted of four primary components: "Governance", "Participation of Women", "Reorganization of Care" and "Monitoring". This paper aims to evaluate: (1) which specific activities of the PPA had the largest effect on the probability of a woman having a vaginal delivery; (2) which primary component of the PPA had the largest effect on the probability of vaginal delivery and (3) which scenarios combining the implementation of different activities planned in the PPA had a higher effect on the probability of vaginal delivery. METHODS: A sample of 12 private hospitals participating in the PPA was evaluated. We used a Bayesian Network (BN) to capture both non-linearities and complex cause-effect relations. The BN integrated knowledge from experts and data from women to estimate 26 model parameters. The PPA was evaluated in 2473 women belonging to groups 1-4 of the Robson classification, who were divided into two groups: those participating or not participating in the PPA. RESULTS: The probability of a woman having a vaginal delivery was 37.7% higher in women participating in the PPA. The most important component of the project that led to an increase in the probability of vaginal delivery was "Reorganization of Care", leading to a 73% probability of vaginal delivery among women in labor. The activity that had the greatest effect on the type of delivery was access to best practices during labor, with a 72% probability of vaginal delivery. Considering the 12 scenarios combining the different activities of the PPA, the best scenarios included: a non-scheduled delivery, access to information about best practices, access to at least 4 best practices during labor and respect of the birth plan, with an 80% probability of vaginal delivery in the best combinations. CONCLUSION: PPA has been shown to be an effective quality improvement program, increasing the likelihood of vaginal delivery in private Brazilian hospitals.

INTRODUCTION: Brazil boasts one of the highest rates of caesarean sections (CS) globally, with nearly 90% of births in private facilities being delivered via CS. In response, the 'Adequate Childbirth Project ­ PPA' was launched as a quality improvement initiative aimed at curbing CS rates in private healthcare. Its goal is to improve the quality of childbirth and reduce the number of CS in private healthcare. The project has four main parts: 'Governance', 'Participation of Women', 'Reorganization of Care', and 'Monitoring'. METHOD: an evaluative study was conducted across 12 private hospitals involved in the PPA, involving 2473 women who were categorized into PPA participants and non-participants. They used a method called a cause-effect network to see which parts of the PPA helped more women have vaginal deliveries. RESULTS: They found that women in the PPA were 37.7% more likely to have a vaginal delivery. Giving women access to good practices during labor and birth was really important. Also, 'Reorganization of Care' was the most important part of the project. It led to a 73% chance of vaginal delivery for women in labor. CONCLUSION: The PPA is effective in helping more women in private hospitals have vaginal deliveries. This means it's a good program for improving childbirth in Brazil's private hospitals.

Assessment of Albumin Usage Patterns and Appropriateness in a Comprehensive Cancer Centre: A retrospective study in Jordan.

Objectives: Albumin is commonly used for various indications; however, there is conflicting data regarding its appropriate use in different clinical cases. This study aimed to determine the pattern and appropriateness of albumin use among cancer patients at the King Hussein Cancer Center in Jordan. Methods: A retrospective analysis was conducted on adult cancer patients who were prescribed albumin between January 2019 and July 2020 in both outpatient and inpatient settings. Data collected included demographics, prescribing services, indications and dosing regimens. A literature review was performed using PubMed to assess the appropriateness of albumin indications and dosing regimens against current guidelines, drug information resources and the package insert. Results: Albumin was prescribed to 1,361 patients during the study period. Each patient received an average of 74.4 ± 89 g of albumin for an average of 2.6 ± 1.8 days. Albumin use was deemed appropriate in 69% of the patients. The critical care service accounted for the highest albumin consumption, with 37% of prescriptions for septic shock. Inappropriate use of albumin was most prevalent in the medical solid tumour services (40.8% of prescriptions), primarily for edema (28%). Conclusion: To the best of the author's knowledge, this study is the first to evaluate albumin use in a large cohort of oncology patients. Approximately one-third of the albumin prescriptions were considered inappropriate. Continuous education on appropriate usage and regular evaluations of guideline adherence are essential to ensure proper utilisation of albumin in cancer care.

Re-evaluating the Morse Fall Scale in obstetrics and gynecology wards and determining optimal cut-off scores for enhanced risk assessment: A retrospective survey.

OBJECTIVE: This study aims to examine the validity of the MFS by analyzing the electronic medical records on fall risk in obstetrics and gynecology wards and determine the optimal cut-off score of the Morse Fall Scale. DESIGN: A retrospective survey. METHODS: The research was conducted in an Obstetrics and Gynecology Hospital and a general hospital. The sample included 136 fall inpatients and 120 no-fall inpatients recruited from January 1st, 2020, to July 10th, 2022. The Morse Fall Scale was analyzed using the gold standard of patients who fell while hospitalized, assessing the area under the Receiver Operating Characteristic curve, sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and Kappa. RESULTS: At cut-off scores of 40, 45,50, and 55, the area under the Receiver Operating Characteristic curve was 0.772, 0.761, 0.749, and 0.763, respectively. The Youden index was 0.543, 0.521, 0.498, and 0.525, while Kappa values were 0.540, 0.518, 0.490, and 0.515. Sensitivity was 0.735, 0.713, 0.640, and 0.625; specificity was 0.808, 0.808, 0.858, and 0.900. The positive predictive values were 0.813, 0.808, 0.837, and 0.876, and the negative predictive values were 0.729, 0.713, 0.678, and 0.679. Accuracy were 0.770, 0.758, 0.742, and 0.754. CONCLUSIONS: The Morse Fall Scale demonstrates good predictive performance for assessing fall risk in gynecology and obstetrics wards. The optimal cut-off score is 40.

Hypoperfusion of periaqueductal gray as an imaging biomarker in chronic migraine beyond diagnosis: A 3D pseudocontinuous arterial spin labeling MR imaging.

BACKGROUND: The periaqueductal gray (PAG) is at the center of a powerful descending antinociceptive neuronal network, and is a key node in the descending pain regulatory system of pain. However, less is known about the altered perfusion of PAG in chronic migraine (CM). AIM: To measure the perfusion of PAG matter, an important structure in pain modulation, in CM with magnetic resonance (MR) perfusion without contrast administration. METHODS: Three-dimensional pseudocontinuous arterial spin labeling (3D-PCASL) and brain structure imaging were performed in 13 patients with CM and 15 normal subjects. The inverse deformation field generated by brain structure image segmentation was applied to the midbrain PAG template to generate individualized PAG. Then the perfusion value of the PAG area of the midbrain was extracted based on the individual PAG mask. RESULTS: Cerebral blood flow (CBF) value of PAG in CM patients (47.98 ± 8.38 mL/100 mg min) was significantly lower than that of the control group (59.87 ± 14.24 mL/100 mg min). Receiver operating characteristic (ROC) curve analysis showed that the area under the curve was 0.77 (95% confidence interval [CI], 0.60, 0.94), and the cutoff value for the diagnosis of CM was 54.83 mL/100 mg min with a sensitivity 84.60% and a specificity 60%. CONCLUSION: Imaging evidence of the impaired pain conduction pathway in CM may be related with the decreased perfusion in the PAG, which could be considered as an imaging biomarker for the diagnosis and therapy evaluation.

Pressure ulcers: a clinical audit to determine compliance against the aSSKINg framework in an adult community nursing setting.

Assessment of pressure ulcer (PU) risk remains a challenge in clinical practice. The first part of this article (Martin and Holloway, 2024) discussed the evidence base underpinning the development of clinical guidelines for PUs alongside the creation of the bundle approach regarding PU prevention. This article, part two, presents the results of a clinical audit that explores compliance against a PU prevention bundle (the aSSKINg framework) in an adult community nursing setting in the south-east of England. The clinical audit was conducted between July-December 2021 and included records of 150 patients. Overall, compliance against the aSSKINg framework was poor, with only two criterion being met: equipment provision for chair and referral to the tissue viability team. Short-term recommendations are that mandatory PU training for staff in the management of PUs should be implemented, and the tissue viability nurse network should be increased. The long-term recommendation was the introduction of the aSSKINg framework as a template into the electronic patient record.

"Sorry, no results found": evaluating LGBTQIA + inclusivity of U.S. cancer centers' websites.

PURPOSE: Cancer care for lesbian, gay, bisexual, transgender, queer, intersex, asexual, and other sexuality and gender diverse (LGBTQIA +) individuals is marked by disparities stemming from a history of discrimination, stigma, and systemic inequities. For LGBTQIA + individuals seeking cancer care, cancer center websites may be a first point of contact with healthcare. Two complementary studies sought to evaluate the LGBTQIA + inclusivity of cancer centers' websites. METHODS: The authors conducted two studies in 2022-2023, reviewing the websites of National Cancer Institute (NCI)-designated cancer centers and Children's Oncology Group (COG)-designated health systems and cancer centers. Reviewers manually searched websites and coded several Yes/No criteria for LGBTQIA + inclusivity. RESULTS: Among the 65 NCI cancer centers' websites in 2023, 66% included a nondiscrimination statement, 71% mentioned LGBTQIA + health disparities, 65% included LGBTQIA + tailored resources, and 66% had articles about LGBTQIA + health. There was a trend of increased inclusivity across categories from 2022 to 2023. Among the 204 COG-designated health system websites in 2023, there were 60 pediatric care websites and 144 lifespan care websites. A total of 79.9% of COG health system websites referenced LGBTQIA + patients (80.0% of pediatric and 79.9% of lifespan sites), 16.7% of COG cancer center websites referenced LGBTQIA + patients in the context of cancer care (6.7% of pediatric and 20.8% of lifespan sites), and 82.4% yielded results when search terms were input (83.3% of pediatric and 81.9% of lifespan sites). CONCLUSIONS: Adult and pediatric cancer centers' websites have varying levels of LGBTQIA + inclusivity based on nondiscrimination statements, articles, and the availability of LGBTQIA + resources. While there have been some improvements in inclusivity on the NCI-designated cancer centers' websites between 2022 and 2023, there is a need for further improvement.
