Novices cannot fill the examiners’ shoes: Evidence of footwear examiners’ expertise in shoe comparisons

The value of a footwear examiner’s opinion centres on their ability to determine whether a particular shoe made an impression with greater accuracy than a novice. However, there has been limited research on the expertise of footwear examiners and the accuracy and reproducibility of their decisions. In the current study, we measured the accuracy and consensus of 31 footwear examiners versus a comparison group of 29 novices. Participants completed 20 ground truth known mock shoe comparisons. Results demonstrated that footwear examiners were more accurate than novices, regardless of comparison difficulty. Overall, on trials where probative decisions were given, examiners made false identifications and false exclusions on a total of 3% and 2% of trials, while novices made false identifications and false exclusions on a total of 19% and 17% of trials. Examiners also demonstrated better consensus in their opinions than novices, although both groups demonstrated low levels of agreement in their responses and variability in their interpretation of the conclusion scale. In summary, these findings support the proposition that footwear examiners show expert-level performance in matching known and unknown footwear impressions. These performance estimates may help the criminal justice system to appropriately value footwear examination evidence.

Agreement on Interpretation of Point-of-Care Ultrasonography for Cardiac Tamponade Among Emergency Physicians.

Cardiac tamponade is an impending calamitous disorder that emergency physicians need to consider and diagnose rapidly. A pericardial effusion with right atrial systolic collapse (earliest sign) or right ventricular diastolic collapse (most specific sign) and a plethoric inferior vena cava are indicators of cardiac tamponade physiology and may be identified with point-of-care ultrasonography (POCUS). The goal of this study is to assess the agreement among emergency physicians with varying levels of sonographic training and expertise in interpreting echocardiographic signs of cardiac tamponade in adult patients. Methods: Emergency physicians at different levels of training as sonographers were surveyed at didactic conferences at three major academic medical centers in northern New Jersey. Two cardiologists were also included in the study for comparison. Survey respondents were shown 15, 20-second video clips of patients who had presented to the emergency department (ED) with or without significant pericardial effusions and were asked to rate whether tamponade physiology was present or not. Data were collected anonymously on Google Forms (Google LLC, Mountain View, CA)and included self-reported levels of POCUS expertise and level of training. Data were analyzed using Fleiss' kappa (k). All patients had an echocardiogram performed by the department of cardiology within 24 hours of the POCUS, and the results are presented in the paper. Results: There were 97 participant raters, including attendings, fellows, and resident physicians specializing in adult emergency medicine and two cardiologists. There was a fair degree of inter-rater agreement among all participants in interpreting whether tamponade physiology was present or not. This low level of agreement persisted across self-reported training levels and self-reported POCUS expertise, even at the expert level in both emergency medicine and cardiology specialties. According to the results of our study, there appears to be a low level of agreement in the interpretation of cardiac tamponade in adult patients. The lack of agreement persisted across specialties, self-reported training levels, and self-reported ultrasonographic expertise. This low level of agreement seen amongboth specialists indicates that emergency physicians are not limited in their ability to determine cardiac tamponade on POCUS. This highlights the technical nature of POCUS clips and strengthens the importance of physical exam findings when diagnosing cardiac tamponade in emergency department patients. Further research utilizing POCUS for the diagnosis of tamponade is warranted.

Comparing the Fried frailty phenotype versus the Veterans Affairs frailty index among dialysis dependent patients.

Frailty in dialysis patients is a modifiable disease state which can increase mortality if left untreated but remains underdiagnosed as frailty evaluations can be arduous or time consuming. We evaluate the agreement between a clinical frailty construct (Fried frailty phenotype, FFP) against and an electronic health record-based Veterans Affairs Frailty Index (VAFI) and their association with mortality. A retrospective cohort analysis of 764 participants from the ACTIVE/ADIPOSE study was performed. Frailty as measured by VAFI and FFP was obtained and Kappa statistic estimating concordance between the two scores were calculated. Differences in mortality risk were analyzed according to presence or absence of frailty. When assessing agreement between the VAFI and FFP, the kappa statistic was 0.09 (95% confidence interval [CI] 0.02-0.16) suggesting a low level of agreement. Frailty was independently associated with higher mortality risk (hazards ratio [HR] 1.40-1.42 in fully adjusted models depending upon frailty construct). Discordantly frail patients by construct had a higher risk of mortality though this was not statistically significant after adjustment. However, concordantly frail patients had much higher mortality risk compared to concordantly nonfrail (adjusted HR 2.08, 95% CI 1.44-3.01). Poor agreement between constructs is likely reflective of the multifactorial definition of frailty. While further longitudinal studies are needed to determine if the VAFI would be beneficial in the reassessment of frailty, it may be beneficial as a cue for further frailty testing (e.g., with FFP) with the combination of multiple frail constructs providing improved prognostic information.

Experiments on real-life emotions challenge Ekman's model

Ekman's emotions (1992) are defined as universal basic emotions. Over the years, alternative models have emerged (e.g. Greene and Haidt 2002; Barrett 2017) describing emotions as social and linguistic constructions. The variety of models existing today raises the question of whether the abstraction provided by such models is sufficient as a descriptive/predictive tool for representing real-life emotional situations. Our study presents a social inquiry to test whether traditional models are sufficient to capture the complexity of daily life emotions, reported in a textual context. The intent of the study is to establish the human-subject agreement rate in an annotated corpus based on Ekman's theory (Entity-Level Tweets Emotional Analysis) and the human-subject agreement rate when using Ekman's emotions to annotate sentences that don’t respect the Ekman’s model (The Dictionary of Obscure Sorrows). Furthermore, we investigated how much alexithymia can influence the human ability to detect and categorise emotions. On a total sample of 114 subjects, our results show low within subjects agreement rates for both datasets, particularly for subjects with low levels of alexithymia; low levels of agreement with the original annotations; frequent use of emotions based on Ekman model, particularly negative one, in people with high levels of alexithymia.

Agreement of body adiposity index (BAI), bioimpedance analysis and ultrasound scanning in determining body fat

BACKGROUND: The steadily increasing number of people with obesity requires the development of simple and accurate methodological approaches to assess the absolute and relative amount of body fat mass. The body adiposity index (BAI) is one of the indices proposed to assess the body fat percentage. However, the comparison analysis of common methods, i.e., of bio-electrical impedance analysis and ultrasound scanning, and BAI was not performed for the Russian population.AIM: Comparison analysis of the body fat percentage estimates by bio-electrical impedance analysis, ultrasound scanning, and body adiposity index in the group of adult male and females.MATERIALS AND METHODS: An examination of healthy males and females from Moscow was conducted. Height, weight, waist and hip circumferences were measured. The body fat percentage was obtained by bio-electrical impedance analysis — BIA (ABC-02 Medas), ultrasound scanning — US (BodyMetrixTM, IntelaMetrix), and body adiposity index.RESULTS: 263 females and 134 males aged 18 to 73 years participated in the study. Correlation coefficients between BAI values and the body fat percentage obtained by BIA and US were 0.749 and 0.763 (p<0.000), respectively. Comparison of body fat percentage measurements obtained by BAI, BIA and US showed the low agreement (ССС<0.90) between BAI and other methods in pooled sample as well as in the female and male groups. Comparison of the US and BAI methods revealed higher level of agreement (ССС=0.84 [0.80–0.86]) and no systematic bias. Lower level of agreement was obtained in the group of males.CONCLUSION: Conducted study allows to conclude that, at the individual level, BAI is not an appropriate method for estimating the body fat percentage relatively to other indirect methods. However, all three methods can be used in the group of pooled males and females when testing at the population level.

103 Analysis of Arterial Blood Pressure Waveform Features in a Porcine Model of Burn and Resuscitation

Abstract Introduction Functional arterial blood pressure waveform (ABW) features are incompletely understood in the context of burn injury and resuscitation. In this work, we analyzed the variability of pulse pressure (PPV), systolic pressure (SPV), stroke volume (SVV), and five measures of heart rate variability (HRV) in time and frequency domains as potential indicators of burn resuscitation adequacy in a large total body surface area (TBSA) porcine model with varying degrees of intravenous fluids. Methods Data were collected from 21 anesthetized and mechanically-ventilated pigs (32±4 kg weight, 40% TBSA), which were instrumented for continuous hemodynamic monitoring for 24 hours. Urinary output (UO), hematocrit (HCT) and cardiac output (CO) were also measured at various time points. The animals were divided into Paradigm 1 (P1): no resuscitation (N=7); Paradigm 2 (P2): fluid titration to UO (N=8); and Paradigm 3 (P3): deliberate over-resuscitation with consistent high fluid rates (N=6). We calculated PPV, SPV, SVV, and five widely used HRV measures: normalized low-frequency power (NLF), high-frequency power (NHF), very-low-frequency power (VLF), low-frequency-high-frequency (LFHF) ratio, and the root-mean-squared of the duration difference in consecutive beats (RR-RMS). All features were averaged on an hourly basis and their potential in tracking reference CO and SV was investigated via linear regression and correlation analysis after calibrating the data to SV and CO on an individual basis. Results PPV, SPV, SVV, and RR-RMSE showed statistically distinguishable trends for different paradigms, as depicted in Figure 1, along with averaged trends for lab measurement. PPV, SPV, and SVV tracked the CO the best and were comparable to UO, however, SVV was far superior in tracking SV. A regression analysis between these four features and UO showed a very low level of agreement despite comparable tracking of SV and CO. HRV measures did not distinguish resuscitation paradigms and were inferior in tracking CO and similar in tracking SV to aforesaid features. Conclusions PPV, SPV, SVV, and RR-RMSE may potentially complement UO in the hemodynamic assessment of the burn patients and outperform other HRV measures in general. Future work will optimize the extraction of strategic informative features of ABW analysis in the various fluid status states post-burn injury. Applicability of Research to Practice Titrating burn resuscitation rates to have protocols including PPV, SPV, SVV, and RR-RMSE alongside other standard metrics may offer precision medicine strategies to fine-tune IV fluid rates.

Oxygen Uptake and Bilaterally Measured Vastus Lateralis Muscle Oxygen Desaturation Kinetics in Well-Trained Endurance Cyclists.

The aim of the present study was to compare and analyse the relationships between pulmonary oxygen uptake and vastus lateralis (VL) muscle oxygen desaturation kinetics measured bilaterally with Moxy NIRS sensors in trained endurance athletes. To this end, 18 trained athletes (age: 42.4 ± 7.2 years, height: 1.837 ± 0.053 m, body mass: 82.4 ± 5.7 kg) visited the laboratory on two consecutive days. On the first day, an incremental test was performed to determine the power values for the gas exchange threshold, the ventilatory threshold (VT), and V̇O2max levels from pulmonary ventilation. On the second day, the athletes performed a constant work rate (CWR) test at the power corresponding to the VT. During the CWR test, the pulmonary ventilation characteristics, left and right VL muscle O2 desaturation (DeSmO2), and pedalling power were continuously recorded, and the average signal of both legs' DeSmO2 was computed. Statistical significance was set at p ≤ 0.05. The relative response amplitudes of the primary and slow components of VL desaturation and pulmonary oxygen uptake kinetics did not differ, and the primary amplitude of muscle desaturation kinetics was strongly associated with the initial response rate of oxygen uptake. Compared with pulmonary O2 kinetics, the primary response time of the muscle desaturation kinetics was shorter, and the slow component started earlier. There was good agreement between the time delays of the slow components describing global and local metabolic processes. Nevertheless, there was a low level of agreement between contralateral desaturation kinetic variables. The averaged DeSmO2 signal of the two sides of the body represented the oxygen kinetics more precisely than the right- or left-leg signals separately.

Perception of threat and intent to harm from vocal and facial cues.

What constitutes a "threatening tone of voice"? There is currently little research exploring how listeners infer threat, or the intention to cause harm, from speakers' voices. Here, we investigated the influence of key linguistic variables on these evaluations (Study 1). Results showed a trend for voices perceived to be lower in pitch, particularly those of male speakers, to be evaluated as sounding more threatening and conveying greater intent to harm. We next investigated the evaluation of multimodal stimuli comprising voices and faces varying in perceived dominance (Study 2). Visual information about the speaker's face had a significant effect on threat and intent ratings. In both experiments, we observed a relatively low level of agreement among individual listeners' evaluations, emphasising idiosyncrasy in the ways in which threat and intent-to-harm are perceived. This research provides a basis for the perceptual experience of a "threatening tone of voice," along with an exploration of vocal and facial cue integration in social evaluation.

Reticular Pseudodrusen: Interreader Agreement of Evaluation on OCT Imaging in Age-Related Macular Degeneration

PurposeTo determine the interreader agreement for reticular pseudodrusen (RPD) assessment on combined infrared reflectance (IR) and OCT imaging in the early stages of age-related macular degeneration across a range of different criteria to define their presence.DesignInterreader agreement study.ParticipantsTwelve readers from 6 reading centers.MethodsAll readers evaluated 100 eyes from individuals with bilateral large drusen for the following: (1) the presence of RPD across a range of different criteria and (2) the number of Stage 2 or 3 RPD lesions (from 0 to ≥ 5 lesions) on an entire OCT volume scan and on a selected OCT B-scan. Supportive information was available from the corresponding IR image.Main Outcome MeasuresInterreader agreement, as assessed by Gwet’s first-order agreement coefficient (AC1).ResultsWhen evaluating an entire OCT volume scan, there was substantial interreader agreement for the presence of any RPD, any or ≥ 5 Stage 2 or 3 lesions, and ≥ 5 definite lesions on en face IR images corresponding to Stage 2 or 3 lesions (AC1 = 0.60–0.72). On selected OCT B-scans, there was also moderate-to-substantial agreement for the presence of any RPD, any or ≥ 5 Stage 2 or 3 lesions (AC1 = 0.58–0.65) and increasing levels of agreement with increasing RPD stage (AC1 = 0.08, 0.56, 0.78, and 0.99 for the presence of any Stage 1, 2, 3, and 4 lesions, respectively). There was substantial agreement regarding the number of Stage 2 or 3 lesions on an entire OCT volume scan (AC1 = 0.68), but only fair agreement for this evaluation on selected B-scans (AC1 = 0.30).ConclusionsThere was generally substantial or near-substantial—but not near-perfect—agreement for assessing the presence of RPD on entire OCT volume scans or selected B-scans across a range of differing RPD criteria. These findings underscore how interreader variability would likely contribute to the variability of findings related to the clinical associations of RPD. The low levels of agreement for assessing RPD number on OCT B-scans underscore the likely challenges of quantifying RPD extent with manual grading.Financial Disclosure(s)Proprietary or commercial disclosure may be found after the references.

The low levels of agreement for assessing RPD number on OCT B-scans underscore the likely challenges of quantifying RPD extent with manual grading.

Researching the level of agreement among experts on terms used to describe wounds: An international study.

Establishing a common language that allows univocal and objective communication in describing wounds and their healing is of utmost importance in defining the diagnostic hypothesis and proper wound management. To measure the level of agreement on the description of wounds, an international study was performed among experts of different professional backgrounds on several common terms used to describe ulcerative lesions. A panel of 27 wound care experts anonymously completed a multiple-choice questionnaire on 100 images of 50 ulcerative lesions. The participants were asked to describe each image using a set of pre-defined terms. An expert data analyst interpreted the questionnaires to map the level of agreement on the used terminology. Our findings show a very low level of agreement among experts in using the proposed terminology to describe the wound bed, the wound edge, and the surrounding skin conditions. Efforts should be planned to find a consensus on the correct use of terminology for wound description. To this aim, partnership, consensus, and agreement with educators in medicine and nursing are necessary.

The effect of post-COVID-19 on gustatory and olfactory function: A preliminary case-controlled study.

The aim of the study was to analyze objective and subjective olfactory/gustatory function in post-COVID-19 infection (PCI). Patients with past PCR-confirmed COVID-19 infection and persistent olfactory/gustatory complaints were investigated. Olfactory threshold and identification, gustatory detection, identification, and magnitude scaling were tested. A total of 42 PCI subjects were compared to 41 age- and gender-matched controls with no COVID-19 history. All PCI tested had mild COVID-19 disease. Mean interval between COVID-19 confirmations to testing was 7.4 ± 3.1 months. PCI subjects complained of combined dysfunction in 85.7%, isolated olfactory or gustatory dysfunction in 7.1% each. Combined complaints were significantly higher in PCI (p < 0.001). Objective testing showed significantly higher prevalence of dysfunction in PCI versus controls for hyposmia (73.8%, 12.2%), anosmia (11.9%, 0%), odor identification (68.5%, 83.0%), hypogeusia (23% and 2.4%, respectively), and impaired magnitude scaling, (p < 0.05). All PCI subjects with hypogeusia had abnormal gustatory magnitude scaling. While most PCI subjects complained of combined gustatory and olfactory dysfunction, objective testing showed in the majority an isolated single sense dysfunction, with a low level of agreement between subjective and objective findings. Abnormal objective results for all olfactory and gustatory functions tested may suggest a central rather than peripheral mechanism, although concomitant mechanisms cannot be excluded.

Attitudes and Knowledge Regarding the Therapeutic Use of Cannabinoids among Community Pharmacists: A Pilot Cross-Sectional Study in Amman, Jordan

There is an increasing interest in the therapeutic use of cannabis worldwide, with a number of cannabinoid-derived drugs currently approved by the Food and Drug Administration (FDA) for certain indications. This study was conducted via a printed questionnaire and aimed to explore the attitudes and knowledge regarding the therapeutic use of cannabis and cannabinoids among community pharmacists residing in Amman, Jordan. The results revealed a neutral to low agreement level regarding the medical usefulness of cannabis; however, a higher agreement level was observed for FDA-approved cannabinoid-derived drugs. The majority of the participants reported that they did not learn enough regarding cannabinoids, do not adequately remember what they have learned, and do not actively look for information after graduation. The average percentages of correct identification of cannabis/cannabinoid FDA-approved drug indications, common adverse effects, interacting drugs, and cautions/contraindications were 40.6%, 53%, 49.4%, and 57.3%, respectively, with an overall correct identification rate of 51.1% of the participants. In conclusion, the results indicate an inadequate level of knowledge with a significant room for improvement regarding the various aspects of cannabinoid pharmacology.

Front-of-Pack Nutrition Labels: Comparing the Nordic Keyhole and Nutri-Score in a Swedish Context

The extent to which different front-of-pack nutrition labels (FOPNLs) agree or contradict each other has been insufficiently investigated. Considering the 2020 proposal from the European Commission to create a harmonized FOPNL, the aim of this study was to assess agreements and disagreements between two FOPNL schemes-the Keyhole and the Nutri-Score-in a Swedish context. The current Keyhole criteria and the updated Nutri-Score 2022 algorithm were applied to 984 food items and their nutrient compositions, obtained from the food database of the Swedish Food Agency. Agreements (Keyhole-eligible and Nutri-Score A or B; or not Keyhole-eligible and Nutri-Score C, D, or E) and disagreements (Keyhole-eligible and Nutri-Score C, D, or E, or not Keyhole-eligible and Nutri-Score A or B) were calculated as percentages for all items and by food group. An agreement was found for 81% of included items. The lowest level of agreement was found for the groups of flour, grains, and rice (62% agreement) and for plant-based meat and fish analogues (33% agreement). There is generally a good level of agreement between the Keyhole and the Nutri-Score for food items on the Swedish market. Large disagreements found for plant-based meat and fish analogues, and products based on cereals/grains, highlight important considerations for the development of a harmonized FOPNL within Europe.

Explainable synthetic image generation to improve risk assessment of rare pediatric heart transplant rejection

Expert microscopic analysis of cells obtained from frequent heart biopsies is vital for early detection of pediatric heart transplant rejection to prevent heart failure. Detection of this rare condition is prone to low levels of expert agreement due to the difficulty of identifying subtle rejection signs within biopsy samples. The rarity of pediatric heart transplant rejection also means that very few gold-standard images are available for developing machine learning models. To solve this urgent clinical challenge, we developed a deep learning model to automatically quantify rejection risk within digital images of biopsied tissue using an explainable synthetic data augmentation approach. We developed this explainable AI framework to illustrate how our progressive and inspirational generative adversarial network models distinguish between normal tissue images and those containing cellular rejection signs. To quantify biopsy-level rejection risk, we first detect local rejection features using a binary image classifier trained with expert-annotated and synthetic examples. We converted these local predictions into a biopsy-wide rejection score via an interpretable histogram-based approach. Our model significantly improves upon prior works with the same dataset with an area under the receiver operating curve (AUROC) of 98.84% for the local rejection detection task and 95.56% for the biopsy-rejection prediction task. A biopsy-level sensitivity of 83.33% makes our approach suitable for early screening of biopsies to prioritize expert analysis. Our framework provides a solution to rare medical imaging challenges currently limited by small datasets.

The Yield of Routine Tissue Sampling in Pediatric Gastrointestinal Endoscopy.

Societies' guidelines suggest routine tissue sampling in all children undergoing esophagogastroduodenoscopy and ileocolonoscopy, even in the absence of visible endoscopy abnormalities. We aimed to determine the agreement between endoscopic and histopathological findings in pediatric endoscopy and to assess the yield of routine biopsies from all sites. Since January 2019, our endoscopy institute protocol has included routine biopsies sampling from the esophagus, stomach, duodenum, ileum, and colon in all diagnostic procedures. Agreement between tests was done using the kappa coefficient ( κ ). The study included all endoscopies performed during 2019. In total, 541 diagnostic endoscopies were done during the study period with 434 (80%) esophagogastroduodenoscopy and 107 (20%) were ileocolonoscopy. Compared to histology, endoscopic findings performance were: esophagus-sensitivity 33%, specificity 98%; stomach-sensitivity 60%, specificity 89%; duodenum-sensitivity 50%, specificity 97%; duodenal bulb-sensitivity 47%, specificity 89%; terminal ileum-sensitivity 82%, specificity 100%; colon-sensitivity 84%, specificity 96%. Assessment of concordance between endoscopic and histopathologic findings reveals an overall low level of agreement in esophagogastroduodenoscopy ( κ of 0.39, 0.51, 0.53, and 0.24 for the esophagus, stomach, duodenal second part, and bulb, respectively), and good agreement in ileocolonoscopy ( κ of 0.88 and 0.81 for the ileum and colon, respectively). Endoscopy findings are highly specific for histologic pathology, whereas the absence of findings correlates poorly with histologic findings. Ileocolonoscopy shows better agreement than esophagogastroduodenoscopy. Our data support routine tissue sampling in pediatric endoscopy.

Comparison of Horizontal White-to-white Diameter Measured Using Four Devices

Purpose: To compare the horizontal white-to-white (WTW) diameter measured using four devices.Methods: We measured the horizontal WTW diameter of 52 eyes of 52 patients using the IOL Master 500, ANTERION, OA-2000, and Pentacam HR devices. Repeated-measures analysis of variance was used to compare the measurements. Correlations between the measurements were evaluated using the Pearson correlation test. Agreement between measurements obtained using different instruments was confirmed using a Bland-Altman plot.Results: The mean horizontal WTW diameters obtained using IOL Master 500, ANTERION, OA-2000, and Pentacam HR were 11.65 ± 0.39, 11.52 ± 0.44, 11.51 ± 0.52, and 11.28 ± 0.41 mm, respectively. The horizontal WTW diameters obtained using IOL Master 500 and Pentacam HR were the largest and smallest, respectively. There was a statistically significant difference in mean diameter between IOL Master 500 and ANTERION (&lt;i&gt;p&lt;/i&gt; = 0.03), as well as between Pentacam HR and the remaining three devices (all &lt;i&gt;p&lt;/i&gt; &lt; 0.001). There were positive correlations between the measurements obtained using the different devices (all r &gt; 0.6, &lt;i&gt;p&lt;/i&gt; &lt; 0.001). The 95% limits of agreement between the measurements were 0.808-1.619 mm.Conclusions: There were statistically significant differences in horizontal WTW diameter between IOL Master 500 and ANTERION, and between IOL Master 500 and Pentacam HR, but not between IOL Master 500 and OA-2000. Measurements obtained using IOL Master 500 and the remaining three devices are not interchangeable because of their low level of agreement.

(Dis)Agreement with Dysthanasia, Religiosity and Spiritual Experience as Factors Related to Nurses' Workload during End-of-Life Care.

This study intended to investigate whether the workload of nurses in the course of providing end-of-life care correlated with their religiousness, spiritual experience and level of agreement with dysthanasia procedures. The respondents included 279 nurses from four Croatian hospitals. A structured and validated instrument was applied. Almost 90% of respondents are religious, and almost 45% of them have daily spiritual experiences. Respondents, especially those with high levels of religiousness and spiritual experience, express a low level of agreement with dysthanasia (mean = 58.21; score = 25-125). Moreover, nurses self-rated (on a scale of 1-5) their workload as quite high, especially when performing contradictory tasks imposed on them by their superiors (mean = 3.05) and during direct contact with dying patients and their family members (mean = 2.56). This significantly highest level of workload was experienced by the youngest nurses (p = 0.01) and nurses with little work experience (p &lt; 0.01). This study also indicated that nurses who agree with dysthanasia experienced a higher level of workload when providing end-of-life care (r = 0.178; p &lt; 0.01), while more frequent spiritual experiences reduced the level of workload (r = -0.205; p &lt; 0.01). A deeper understanding of nurses' attitudes toward dysthanasia, as well as of their religiousness and spiritual experiences, may ensure the collection of data beneficial to the timely identification of potential risks caused by workload.

Perceptions of Primary Caregivers on Children's Weight Status Versus Actual Weight Status in Children Aged 6-15 Years - China, 2021.

Childhood obesity has been linked to adverse health outcomes during both childhood and adulthood. An accurate understanding of children's weight status by primary caregivers is essential for effective weight management strategies. The data utilized in this study were obtained from the 2021 Nutrition Improvement Program for Rural Compulsory Education Students in China. It was found that over one-third of primary caregivers underestimated their children's weight status, and more than half of the primary caregivers of overweight or obese children underreported the weight status of those children. A low level of agreement was observed between primary caregivers' perceptions of their children's weight status and the actual weight status. There is a relatively higher underestimation of children's weight in China, which necessitates more effective strategies to enhance the primary caregivers' perception of their children's weight status, especially in primary caregivers of males, younger children and children in urban areas.

A Scoping Review of Pediatric Mass-Casualty Incident Triage Algorithms.

For the pediatric population, there is no consensus on which triage system to use for mass-casualty incidents (MCI). A scoping review was conducted to identify the most accurate triage system for pediatric patients in MCIs. MEDLINE (NLM, Bethesda, MA, USA), Embase (Elsevier Inc., Amsterdam, Netherlands), CINAHL (EBSCO Information Services, Ipswitch, MA, USA), and The Cochrane CENTRAL Register of Controlled Trials (John Wiley & Sons, Hoboken, NJ, USA), as well as Scopus (Elsevier Inc., Amsterdam, Netherlands), Global Health (Centre for Agriculture and Bioscience International, Wallingford, UK), Global Health Archive (Centre for Agriculture and Bioscience International, Wallingford, UK), and Global Index Medicus (World Health Organization, Geneva, Switzerland) were searched for relevant studies that were divided into 3 categories: accuracy of a single system, comparison of 2 or more primary triage system and comparison of secondary triage systems. Grey literature was also searched. 996 studies were identified from which 18 studies were included. Systems studied were found to have poor inter-rater reliability, had a low level of agreement between providers, had missed critically ill patients or were not externally validated. 11 studies compared pediatric MCI triage algorithms using different strategies and the most accurate algorithm was not identified. A recently developed secondary triage system, specifically for pediatric patients, was found to perform better than the comparison triage system. Although some algorithms performed better than others, no primary triage algorithm was accurate enough for the pediatric population. However, only 1 secondary triage algorithm was found to be superior to the others.

Agreement between ultrasonic bubble grades using a handheld self-positioning Doppler product and 2D cardiac ultrasound.

Intravascular bubble load after decompression can be detected and scored using ultrasound techniques that measure venous gas emboli (VGE). The aim of this study was to analyse the agreement between ultrasonic bubble grades from a handheld self-positioning product, the O'Dive™, and cardiac 2D ultrasound after decompression. VGE were graded with both bilateral subclavian vein Doppler ultrasound (modified Spencer scale) and 2D cardiac images (Eftedal Brubakk scale). Agreement was analysed using weighted kappa (Kw). Analysis with Kw was made for all paired grades, including measurements with and without zero grades, and for each method's highest grades after each dive. A total of 152 dives yielded 1,113 paired measurements. The Kw agreement between ultrasound VGE grades produced by cardiac 2D images and those from the O'Dive was 'fair'; when zero grades were excluded the agreement was 'poor'. The O'Dive was found to have a lower sensitivity to detect VGE compared to 2D cardiac image scoring. Compared to 2D cardiac image ultrasound, the O'Dive yielded generally lower VGE grades, which resulted in a low level of agreement (fair to poor) with Kw.
