ABSTRACT

BackgroundAnxiety is highly prevalent among pediatric oncology patients. Weighted blankets are a potential intervention to address anxiety for pediatric oncology patients. The goal of this work is to assess the effectiveness of weighted blankets in reducing anxiety for pediatric oncology patients. Method: A randomized 2 × 2 cross-over design was utilized. Newly diagnosed pediatric oncology patients between the age of 4 and 17 were included. All participants also needed to pass seriation screening to be able to eligible for the study. Participants were randomized to one of two arms: weighted blanket on first infusion visit after enrollment then usual care on second visit (WB:UC) or usual care on first infusion visit after enrollment then weighted blanket (UC:WB) on second visit. Anxiety via Children’s Anxiety Meter-State (CAM-S) was collected pre- and postinfusion visit. Descriptive statistics were conducted to describe the data. A linear mixed model with interaction effects was conducted to assess the treatment effect of the weighted blanket. Results: There were 26 participants who were enrolled in the study. Twenty-four with complete information were included in the analysis. Regression models revealed that CAM-S measure reduced by -0.71 (95% CI: [-1.25 to -0.19], p = .02). WB had more impact on the second visit (β = -0.51, -1.92 to 0.88, 0.97). Discussion: There was significant reduction in anxiety postinfusion. While further research is needed, this study highlights not only the impact of weighted blankets, but of nursing care on anxiety for pediatric oncology patients.

ABSTRACT

Biological motion perception plays a crucial role in understanding the actions of other animals, facilitating effective social interactions. Although traditionally viewed as a bottom-up driven process, recent research suggests that top-down mechanisms, including attention and expectation, significantly influence biological motion perception at all levels, particularly highlighted under complex or ambiguous conditions. In this study, we investigated the effect of expectation on biological motion perception using a cued individuation task with point-light display (PLD) stimuli. We conducted three experiments investigating how prior information regarding action, emotion, and gender of PLD stimuli modulates perceptual processing. We observed a statistically significant congruency effect when preceding cues informed about action of the upcoming biological motion stimulus; participants performed slower in incongruent trials compared to congruent trials. This effect seems to be mainly driven from the 75% congruency condition compared to the non-informative 50% (chance level) validity condition. The congruency effect that was observed in the action experiment was absent in the emotion and gender experiments. These findings highlight the nuanced role of prior information in biological motion perception, particularly emphasizing that action-related cues, when moderately reliable, can influence biological motion perception. Our results are in line with the predictive processing framework, suggesting that the integration of top-down and bottom-up processes is context-dependent and influenced by the nature of prior information. Our results also emphasize the need to develop more comprehensive frameworks that incorporate naturalistic, complex and dynamic, stimuli to build better models of biological motion perception.

ABSTRACT

AIM: Hearing loss occurs more frequently in preterm children. However, the influence of prematurity itself is unclear. We examined whether risk factors for hearing loss differ between preterm and term infants.

METHODS: We conducted a systematic search of three databases in March 2023 for studies comparing risk factors for hearing loss in preterm and term children. Studies on postnatal trauma, chemotherapy or infections after the age of 5 years were excluded. Risk of bias was assessed. Data were extracted and analyzed using logistic regression to yield odds ratios (95% confidence interval).

RESULTS: Of 10 300 studies screened, 16 met the inclusion criteria, including 9059 preterm and 10 048 term children. Only one study compared risk factors between preterm and term infants as primary outcomes. It identified an increased risk in the preterm but not term group with mechanical ventilation exceeding 5 days, sepsis, and ototoxic medication. No significant differences were found when both groups shared these risk factors, suggesting that prematurity may not be an independent risk factor. Other studies reported variable results.

CONCLUSION: Evidence of different effect sizes of risk factors in preterm and term children remains inconclusive. Preterm children acquire more risk factors in the neonatal period.

ABSTRACT

BACKGROUND: Regular blood sampling to monitor RBC mass in anemic cats can exacerbate anemia. Laboratory-based reporting can delay clinical decisions. A hand-held hemoglobinometer, HemoCue Hb 201⁺ (HC-201), requires only one drop of blood (10 μL) and provides results within 1 min.

OBJECTIVES: This preliminary study aimed to evaluate the utility of HC-201 in cats and investigate the impact of potential interferents on its performance.

METHODS: One hundred and fifty-four venous blood samples in EDTA from 93 cats were analyzed. Hemoglobin concentration was measured once using an ADVIA 2120 analyzer and compared to the mean of 2-3 replicate measurements from an HC-201. Agreement and systematic bias between HC-201 and ADVIA results, along with precision between HC-201 replicates, were assessed using Lin’s concordance correlation coefficient, non-parametric Bland-Altman, Passing-Bablok regression, and intraclass correlation coefficient. The performance of HC-201 in the presence of anemia, leukocytosis, azotemia, lipemia, icterus, hemolysis, and peripheral versus jugular venipunctures was assessed using Wilcoxon rank-sum tests.

RESULTS: Passing-Bablok analysis revealed a significant constant bias (intercept = -2.242, 95% CI: -4.042 to -0.667) but no significant proportional bias (slope = 1.015, 95% CI: 1.000-1.032). HC-201 demonstrated excellent agreement (ρ_c = 0.989) and precision (ICC = 0.997) with a median bias of -0.67 g/L (p = 0.001). The total observed error was 3.02%, within the allowable limits defined by international standards. Neither anemia, leukocytosis, azotemia, lipemia, nor venipuncture site influenced HC-201 measurements. Samples with icterus and hemolysis were insufficient in number for statistical comparison.

CONCLUSIONS: This preliminary study indicates that HC-201 offers reliable point-of-care monitoring for hemoglobin concentration in cats.

ABSTRACT

PURPOSES: Suppressing noise can effectively promote image quality and save radiation dose in clinical imaging with x-ray computed tomography (CT). To date, numerous statistical noise reduction approaches have ever been proposed in image domain, projection domain or both domains. Especially, a multiscale decomposition strategy can be exploited to enhance the performance of noise suppression while preserving image sharpness. Recognizing the inherent advantage of noise suppression in the projection domain, we have previously proposed a projection domain multiscale penalized weighted least squares (PWLS) method for fan-beam CT imaging, wherein the sampling intervals are explicitly taken into account for the possible variation of sampling rates. In this work, we extend our previous method into cone-beam (CB) CT imaging, which is more relevant to practical imaging applications.

METHODS: The projection domain multiscale PWLS method is derived for CBCT imaging by converting an isotropic diffusion partial differential equation (PDE) in the three-dimensional (3D) image domain into its counterpart in the CB projection domain. With adoption of the Markov random field (MRF) objective function, the CB projection domain multiscale PWLS method suppresses noise at each scale. The performance of the proposed method for statistical noise reduction in CBCT imaging is experimentally evaluated and verified using the projection data acquired by an actual micro-CT scanner.

RESULTS: The preliminary result shows that the proposed CB projection domain multiscale PWLS method outperforms the CB projection domain single-scale PWLS, the 3D image domain discriminative feature representation (DFR), and the 3D image domain multiscale nonlinear diffusion methods in noise reduction. Moreover, the proposed method can preserve image sharpness effectively while avoiding generation of novel artifacts.

CONCLUSIONS: Since the sampling intervals are explicitly taken into account in the projection domain multiscale decomposition, the proposed method would be beneficial to advanced applications where the CBCT imaging is employed and the sampling rates vary.

ABSTRACT

OBJECTIVE: Describe the characteristics and predictors of emergency department (ED) patients who ‘did not wait’ (DNW).

METHODS: Data linkage study using routinely collected public hospital data in New South Wales, Australia. Cases were included if an initial ED episode of care occurred between January 2021 and December 2022 with an ED mode of separation of DNW. The main outcome was representation to an ED within 7 days of the initial DNW episode of care, and the secondary outcome was 30-day mortality from the initial DNW date. Frequent presenters were those with ≥ 10 ED episodes of care within 365 days. Predictors for representation were determined using logistic regression, presented as odds ratio [95% confidence interval].

RESULTS: The 7-day representation rate after a DNW episode was 14.8% (n = 29,030). Of those, 23.1% presented to a different hospital. 30-day mortality was significantly higher in those who were represented within 7 days versus those who did not represent within 7 days (0.4% vs. 0.1%, p < 0.001). The main predictors of representation within 7 days were: frequent presenters (4.35 [4.13-4.58], p < 0.001), increasing age, with those aged > 85 years having the highest odds of representation (1.71 [1.58-1.86], p < 0.001) and initial presentation during the evening (6:00 PM-11:59 PM; 1.49 [1.44-1.53], p < 0.001).

CONCLUSION: 14.8% of patients who do not wait for care in an ED are represented within 7 days, approximately one quarter presenting to a different facility. Identifying predictors for those patients associated with DNW presentations provides evidence around patient safety and quality of care issues.

ABSTRACT

This study presents a systematic review of reviews published in Frontiers in Psychology (2010-2024) to examine methodological and conceptual advances in educational psychology. The objective is to synthesize research trends over 14 years and explore global challenges, such as the digitalization of education and the integration of emerging technologies. Following PRISMA guidelines, a comprehensive search was conducted in Frontiers in Psychology, Web of Science, and Scopus, identifying 392 reviews. The selection process involved duplicate removal, title and abstract screening, and full-text evaluation, applying predefined inclusion and exclusion criteria to ensure methodological rigor. Data extraction and classification were carried out using an Excel-based structured database, analyzing publication years, methodological design, data sources, statistical and qualitative analysis methods, validation approaches, theoretical frameworks, thematic areas, geographical distribution, study limitations, reported results, practical applications and study populations. The methodological analysis highlights the predominance of systematic reviews, the increasing adoption of qualitative and mixed-method approaches, and a growing emphasis on digital tools and artificial intelligence. The study also reveals significant regional disparities in research output, with some regions being notably underrepresented. Beyond identifying trends, this review of reviews illustrates how psychology adapts to contemporary educational challenges through interdisciplinary methodologies and evidence-based strategies. The findings provide valuable insights into the evolving challenges in educational psychology, reinforcing the role of Frontiers in Psychology in driving methodological innovation and scholarly discourse. Furthermore, they contribute to the advancement of inclusive and sustainable educational practices aligned with the Sustainable Development Goals (SDGs). Future research should focus on meta-analyses of emerging trends, longitudinal methodological studies, and strategies to address regional imbalances, fostering a more globally representative perspective.

ABSTRACT

PURPOSE: Previous studies have suggested housework might reduce self-stigma and psychiatric symptoms, but it had not been validated in severe mental illness (SMI) patients. Considering gender differences, we examined the relationship between housework, self-stigma, and psychiatric symptoms to link family, social, and disease factors, aiding rehabilitation from a “life-oriented” perspective, promoting patients from “passive treatment” to “active life reconstruction”.

PATIENTS AND METHODS: We collected 486 questionnaires from SMI patients in Shandong, China (210 men, 276 women, 124 in 0-40 age group, 244 in 41-64 age group, and 118 in 65 or older age group). Brief Psychiatric Rating Scale, Self-Stigma Scale for Chronic Illness 8-item version were used to measure psychiatric symptoms and self-stigma. Housework and demographic-variables were collected through a questionnaire complied by our research group. Linear regression explicit the relationship between the study variables, based on which a mediation analysis is established to verify the internal mechanism which controls confounding variables (age, religion, marriage, education, occupation, labor capacity, living alone, liability, chronic disease, disease status).

RESULTS: Most participants did housework for less than 1 hour, with men more likely than women (76.2% vs 56.2%). Housework reduced psychiatric symptoms in both genders (men: β = -5.563 (95% CI = -9.513, -1.613), P <0.01, and women: β = -4.088 (95% CI = -7.706, -0.469), P <0.01). However, housework only lowered self-stigma in women (β = -2.322 (95% CI = -3.922, -0.723), P <0.01). Self-stigma fully mediated the housework and psychiatric symptoms (indirect effect = -2.228, 95% CI = -4.046, -0.716).

CONCLUSION: Housework alleviated psychiatric symptoms in both genders, but only reduced the self-stigma of disease in women, suggesting its potential as a modifiable rehabilitation intervention.

LIMITATION: The cross-sectional design precludes causal inferences, self-reported data may introduce recall bias, the Shandong-based sample limits generalizability, unmeasured confounders (eg, medications, comorbidities) warrant further study, and the small sample size may reduce statistical power.

ABSTRACT

PURPOSE: To investigate the efficacy and safety of amphotericin B colloidal dispersion (ABCD) in treating invasive pulmonary fungal disease (IPFD) through nebulized inhalation combined with intravenous therapy.

METHODS: Patients diagnosed with IPFD who received ABCD from October 2023 to March 2024 were retrospectively enrolled. The treatment protocol for patient was determined by clinicians according to the patient’s condition and clinical practice. According to the treatment protocol, patients were divided into two groups: the ABCD nebulized inhalation combined with intravenous injection (combined therapy group) and the ABCD intravenous injection (intravenous therapy group). Clinical characteristics, ABCD administration (dose and duration), treatment outcomes (favorable response rate), and adverse events (AEs) were compared between the two groups.

RESULTS: Thirty-two patients were included, with 16 in each group. No significant differences were observed in the clinical characteristics between the two groups. In the combined therapy group, the numbers of proven, probable, and possible cases were 4 (25.00%), 7 (43.75%), and 5 (31.25%), respectively. In the intravenous injection treatment group, 1 (6.25%), 11 (68.75%), and 4 (25.00%) patients were proven, probable, and possible, respectively. The total dose of ABCD was slightly lower in the combined therapy group than in the intravenous therapy group (1675 vs 1800, P=0.611), although the difference was not statistically significant. The duration of combined therapy group was significantly shorter than that of the intravenous therapy group (8 vs 12, P=0.032), indicating that combination therapy can decrease the risk of hospital-acquired infections. The favorable response rate of the combined therapy group was significantly higher than that of the intravenous therapy group (93.75% vs 62.50%, P=0.033). Elevated urea levels emerged as the most common AE in the combined therapy group (68.75%) and intravenous therapy group (50.00%), no statistically significant difference was observed in the incidence of AEs between the two groups. All 32 patients (100%) completed the prescribed treatment regimen, and no patients withdrew from the study due to AEs.

CONCLUSION: The efficacy of ABCD nebulized inhalation combined with intravenous injection was superior to intravenous injection of ABCD alone in the treatment of IPFD, with comparable safety and shortened medication time.
