Published: October 2024

Abstract
Background
Given the characteristics of the rehabilitation therapy specialty and the drawback of the traditional didactic teaching approach, we developed the innovative teaching approach from the students’ perspective using the person–environment–occupation (PEO) model. The new model was developed from the original PEO model to be applied in pedagogical contexts and tailored to the characteristics of an application-oriented specialty, such as rehabilitation therapy. The present study aimed to examine the perceived effectiveness of the PEO innovative teaching model applied to rehabilitation therapy students.

Methods
A pre–post descriptive study was conducted to compare the perceived effectiveness of the PEO innovative teaching model for two consecutive student cohorts. A purposive sampling method was used to recruit students from two cohorts of junior medical students majoring in rehabilitation therapy in the spring semesters of 2020 and 2021. A questionnaire was developed to evaluate the perceived effectiveness of the PEO innovative teaching model. SPSS version 26.0 was used to perform data analysis.

Results
A total of 112 students were included in the study and completed both pre- and post-tests. Of 112 received questionnaires, 101 were considered as valid questionnaires after the quality check (effective rate 90.18%). In the 2020 and 2021 cohorts, students rated the PEO innovative teaching model significantly higher than the didactic teaching approach in the following aspects: the teaching content is highly professional and valuable; the course is extensively expounded; the clinical reasoning is strengthened; problem-solving ability is developed; communication skills are improved; and teamwork skills are developed.

Conclusion
The PEO innovative teaching model was perceived to be an effective teaching strategy to enhance students’ academic performance. In addition, three core skills including clinical reasoning, problem-solving ability, and communication skills were improved by the PEO innovative teaching model.

Abstract
Background
Leadership in nursing is crucial for delivering high-quality healthcare and ensuring positive outcomes for patients, staff, and institutions. Many nurses in leadership positions lack formal training, which can compromise their effectiveness. This study aims to evaluate the effect of a leadership development program utilizing 360-degree feedback on head nurses’ leadership practices.

Methods
A true-experimental design was employed in three healthcare institutions. The study involved 80 head nurses (40 intervention, 40 control), 240 staff nurses, and 29 supervisors. The intervention group participated in a six-week leadership development program using 360-degree feedback. Data were collected pre- and post-intervention using the Leadership Development and 360-Degree Feedback Knowledge Questionnaire and the Leadership Practices Inventory (LPI).

Results
The intervention group showed significant improvements in leadership knowledge and practices across all dimensions. Knowledge scores increased from 25.1 ± 8.8 to 93.0 ± 5.1 post-intervention, maintaining at 83.2 ± 7.1 at follow-up. Self-assessed leadership scores improved from 88.1 ± 6.0 to 97.5 ± 2.7, and 98.5 ± 2.0 at follow-up. Supervisor and staff assessments also showed substantial increases. Multiple linear regression analyses confirmed the strong positive impact of the intervention on leadership outcomes.

Conclusion
The leadership development program using 360-degree feedback significantly enhanced head nurses’ leadership knowledge and practices. The results suggest that such programs can improve leadership capabilities in healthcare settings, leading to better patient care and organizational performance. Future research should address group homogeneity and explore long-term impacts on patient outcomes.

Abstract
Background
Regular physical activity (PA) has been proven to help prevent non-communicable diseases and is beneficial for disease management in chronically ill populations. Physical inactivity and recreational screen-based media (SBM) use are related to poor health outcomes and common among youth. This study aimed to (1) investigate PA levels and recreational SBM use of adolescents with JIA over time and (2) compare these behaviours with those of their peers.

Methods
Data from JIA patients and their peers enrolled in the inception cohort study ICON at 11 German centers were analyzed. Individuals aged 13 and over were followed prospectively with questionnaires concerning PA level, recreational SBM use, and health-related quality of life (HRQoL) at a two-year interval. Group by time interactions were analyzed using linear mixed models.

Results
Data of 214 patients (mean age at first documentation 14.4 ± 0.9 years, female 63%) and 141 peers could be considered. At first documentation, patients were less physically active compared to their peers (p < 0.001). In contrast to their peers, patients’ PA levels increased over time (OR 3.69; 95% CI: 1.01–13.50, p = 0.048). Mean screen time did not differ significantly between patients and peers (first documentation: 3.5 h vs. 3.0 h, p = 0.556; follow-up: 3.6 h vs. 3.3 h, p = 0. 969). During the observation period, male patients reported higher PA levels than female patients, but also higher screen time levels. While low socioeconomic status (SES) (OR 14.40; 95%-CI: 2.84–73.15) and higher cJADAS-10 score (OR 1.31; 95%-CI: 1.03–1.66) increased the likelihood for high SBM use (≥ 4.5 h/d), higher PedsQL psychosocial health score (OR 0.93; 95%-CI: 0.88–0.99) was associated with a decreased likelihood.

Conclusions
Adolescents with JIA become more physically active over the disease course and achieve comparable levels of PA and recreational screen time to their peers. However, the vast majority appear to be insufficiently physically active. Future interventions to promote healthy lifestyles should include gender and SES as important determinants to reach most vulnerable groups.

Published: October 2024

Abstract
Background
Previous research has indicated that extracellular vesicles (EVs) potentially play significant roles in multiple ageing phenotypes. This study uses a factorial experimental design to explore the interactions between circulating EVs and bone marrow-derived macrophages (BMDMs) isolated from young (7–12 weeks) and aged (70–90 weeks) mice.

Results
In this study, plasma EVs from young (Y_EV) and aged (O_EV) mice were isolated and compared based on abundance, size, and miRNA cargo. Compared to some previous studies, we found relatively few differences in EV miRNA cargo between Y_EVs and O_EVs. Young and old EVs were then used to stimulate naïve BMDMs isolated from young (Y_BMDM) and aged (O_BMDM) mice. A panel of five “M1” and six “M2” macrophage markers were used to assess the degree of polarisation. Our results revealed differences in the immunomodulatory effects of Y_EVs and O_EVs in Y_BMDMs and O_BMDMs. Y_EVs induced less pro-inflammatory gene expression, while O_EVs exhibited a more varied impact, promoting both pro- and anti-inflammatory markers. However, neither EV population induced a clearly defined ‘M1’ or ‘M2’ macrophage phenotype. We also report that EVs elicited responses that differed markedly from those induced by whole plasma. Plasma from old mice had strong pro-inflammatory effects on Y_BMDMs, increasing Il1b, Nlrp3 and Tnfa. However, O_EVs did not have these effects, supporting current evidence that EVs are a separate component of circulating factors during ageing. More research is needed to elucidate specific factors involved in inflammageing processes.

Conclusions
Our findings reveal age-related differences in EV cargo and function, with young EVs tending to suppress inflammatory markers more effectively than aged EVs. However, this is not straightforward, and EVs often promoted both M1 and M2 markers. These results suggest that EVs are a distinct component of circulating factors and hold potential for therapeutic strategies aimed at mitigating age-related inflammation and immune dysregulation.

AbstractBrain microvascular dysfunction is an important feature of Alzheimer’s disease (AD). To better understand the brain microvascular molecular signatures of AD, we processed and analyzed isolated human brain microvessels by data-independent acquisition liquid chromatography with tandem mass spectrometry (DIA LC–MS/MS) to generate a quantitative dataset at the peptide and protein level. Brain microvessels were isolated from parietal cortex grey matter using protocols that preserve viability for downstream functional studies. Our cohort included 23 subjects with clinical and neuropathologic concordance for Alzheimer’s disease, and 21 age-matched controls. In our analysis, we identified 168 proteins whose abundance was significantly increased, and no proteins that were significantly decreased in AD. The most highly increased proteins included amyloid beta, tau, midkine, SPARC related modular calcium binding 1 (SMOC1), and fatty acid binding protein 7 (FABP7). Additionally, Gene Ontology (GO) enrichment analysis identified the enrichment of increased proteins involved in cellular detoxification and antioxidative responses. A systematic evaluation of protein functions using the UniProt database identified groupings into common functional themes including the regulation of cellular proliferation, cellular differentiation and survival, inflammation, extracellular matrix, cell stress responses, metabolism, coagulation and heme breakdown, protein degradation, cytoskeleton, subcellular trafficking, cell motility, and cell signaling. This suggests that AD brain microvessels exist in a stressed state of increased energy demand, and mount a compensatory response to ongoing oxidative and cellular damage that is associated with AD. We also used public RNAseq databases to identify cell-type enriched genes that were detected at the protein level and found no changes in abundance of these proteins between control and AD groups, indicating that changes in cellular composition of the isolated microvessels were minimal between AD and no-AD groups. Using public data, we additionally found that under half of the proteins that were significantly increased in AD microvessels had concordant changes in brain microvascular mRNA, implying substantial discordance between gene and protein levels. Together, our results offer novel insights into the molecular underpinnings of brain microvascular dysfunction in AD.

Abstract
Background
MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate gene expression. Perturbations in plasma miRNA levels are known to impact disease risk and have potential as disease biomarkers. Exploring the genetic regulation of miRNAs may yield new insights into their important role in governing gene expression and disease mechanisms.

Results
We present genome-wide association studies of 2083 plasma circulating miRNAs in 2178 participants of the Rotterdam Study to identify miRNA-expression quantitative trait loci (miR-eQTLs). We identify 3292 associations between 1289 SNPs and 63 miRNAs, of which 65% are replicated in two independent cohorts. We demonstrate that plasma miR-eQTLs co-localise with gene expression, protein, and metabolite-QTLs, which help in identifying miRNA-regulated pathways. We investigate consequences of alteration in circulating miRNA levels on a wide range of clinical conditions in phenome-wide association studies and Mendelian randomisation using the UK Biobank data (N = 423,419), revealing the pleiotropic and causal effects of several miRNAs on various clinical conditions. In the Mendelian randomisation analysis, we find a protective causal effect of miR-1908-5p on the risk of benign colon neoplasm and show that this effect is independent of its host gene (FADS1).

Conclusions
This study enriches our understanding of the genetic architecture of plasma miRNAs and explores the signatures of miRNAs across a wide range of clinical conditions. The integration of population-based genomics, other omics layers, and clinical data presents opportunities to unravel potential clinical significance of miRNAs and provides tools for novel miRNA-based therapeutic target discovery.

Abstract

Background
Post-traumatic headache is a disabling secondary headache disorder often attributed to traumatic brain injury and affects millions of individuals worldwide. Few studies have been done on the treatment needs of these patients in emergency departments. The purpose was to compare the effectiveness of ketorolac intravenous versus acetaminophen intravenous in reducing headaches in patients following head trauma.

Methods
This was a semi-experimental study in which the participants were assigned two groups. In the acetaminophen intravenous group, 1 g acetaminophen and in the ketorolac intravenous group, 60 mg of this drug was injected. Statistical analysis was done with IBM SPSS statistical software version 21, and a P-value less than 0.05 was considered statistically significant.

Results
Among samples after 6 h from the injection, the pain score in the ketorolac intravenous group was less than the acetaminophen intravenous group (P = 0.006). Also, the pain reduction rate in the ketorolac intravenous group was more than the acetaminophen intravenous group from before the injection until 2 h after it (P = 0.01) and before injection until 6 h after it (P = 0.001). The frequency of drowsiness in 2 and 6 h after drug administration in the ketorolac intravenous group was lower than the acetaminophen intravenous group, which is significant in 2 h after drug administration (P = 0.038). The verbal analog scale score comparison for two groups 2 h before medicine administration with pain control score (P = 0.03) and 6 h with pethidine use control (P = 0.003) is significant.

Conclusions
According to this study, ketorolac’s intravenous effect on pain control is better than that of acetaminophen intravenous. With more samples, we can express the survey results more decisively in the future.

Published: October 2024

AbstractInformal STEM settings offer valuable opportunities for students, including neurodiverse students, to engage and participate in STEM activities. However, there is a limited information on how to best engage and include neurodiverse students in informal STEM programming. This systematic review aimed to identify the programmatic elements that facilitated the inclusion of K-12 neurodiverse STEM learners in informal STEM programs. In this systematic review, an academic and grey literature search was conducted, where the search resulted in 2632 records and 18 records were included in the systematic review. Records that met inclusion criteria were independently reviewed and assessed for quality by two reviewers using the Mixed Methods Appraisal Tool (MMAT) or a project-based MMAT. This paper describes how informal STEM programs were designed and implemented to foster the participation of neurodiverse K-12 STEM learners. A qualitative synthesis approach was used to identify the programmatic elements that fostered neurodiverse learner participation. Most of the informal STEM programming for neurodiverse youth occurred in after-school settings and with students with autism. Programmatic elements that facilitated the participation of this population in informal STEM were grouped into three categories: (1) environment/learning structure, (2) learning supports, and (3) instructional strategies and tools. Future informal STEM programming and research should expand to include the neurodiverse population in already established informal STEM programs.

Authors: Altaher Ali Mohamad , Foad Amera Morad , Youssef Wael , Ahmed Ahmed Elsharawy 
Published: October 2024

Abstract
Background
Premature myocardial infarction (PMI) is one of the most pressing global issues in modern cardiology. Recently, the incidence of PMI has gradually increased. Researches found that genetics is a major contributor in its development. SIRT1, an extremely conserved class III NAD-dependent deacetylase, has been linked to numerous cardiovascular disorders and engaged in a number of cellular functions. This work investigated the association between SIRT1 SNP rs7069102 in Egyptian patients ≤ 40 years old with premature ST-elevation Myocardial infarction (STEMI).

Methods
This cross sectional, single-center study included patients younger than 40 with STEMI (PMI group, n = 140) and a control group (n = 140) of healthy subjects of comparable age. In addition to clinical examination and standard tests, all participants underwent echocardiography, coronary angiography, SIRT1 (rs7069102) genotyping, and nitric oxide assay.

Results
The risk for PMI was increased in CG or CC genotype carriers of SIRT1 gene rs7069102 (OR: 3.93, 95% Cl: 2.25–6.86), as did carriers of the C allele (OR: 2.26, 95% Cl: 1.65–3.86). In the PMI group, endothelial nitric oxide synthase (eNOS) was significantly decreased; whereas, neuronal nitric oxide synthase (nNOS) was significantly increased.

Conclusions
SIRT1 single-nucleotide polymorphism (rs7069102) may confer an increased risk for PMI in young Egyptian patients with affecting endothelial nitric oxide synthase protein expressions. Traditional cardiovascular risk factors are prevalent in patients with PMI, with dietary behaviors, obesity, diabetes and dyslipidemia serving as independent risk factors for PMI.

Estimation of weighted computed tomography dose index (CTDIw) in megavoltage computed tomography (MVCT)
Authors: Devi Rama , Singh Balbir , Basandrai Deepak , Passi Kamlesh , Singh Vikram 
Published: October 2024

Abstract
Introduction
Advanced technologies in radiation treatment deliveries require high accuracy and precision in setup before treatment to get accurate dose delivery for planned target volumes. During imaging procedures, patients are getting extra doses from kilovoltage computed tomography (KVCT) and megavoltage computed tomography (MVCT). Computed tomography dose index is an important dosimetric parameter to know the degree of radiation-induced side effects.

Aim
The main aim of this study is to quantify the dose received by patients during MVCT imaging procedures, weighted computed tomography dose index (CTDIw), volume computed tomography dose index (CTDIvol) and dose length product (DLP).

Methods and materials
This study has been performed on Radixact X9 LINAC machine with 6MV flattening filter-free (FFF) photon beam for treatment and imaging with 3.5 MeV average photon energy. CTDIw and dose length product (DLP) have been calculated for different scanning lengths 18 cm, 10 cm and 0.7 cm with fine, normal and coarse modes with standard imaging A1SL1 ion chamber, cheese phantom and tomoelectrometer.

Results
CTDIw, CTDIvol, and DLP have been calculated with cheese phantom using A1SL1 ion chamber. CTDIw for 0.7 cm is 2.16 cGy, 1.14 cGy and 0.77 cGy for fine normal and coarse modes, respectively.

Conclusion
CTDIw is a dosimetric index to know the dose levels at center and periphery of patient according to scan length. It gives an idea about how much additional dose is received by the patient during the imaging procedures. High pitch gives the lesser absorbed dose. DLP gives the knowledge about stochastic effects from radiation to patients after MVCT.
