Introduction: The discourse surrounding differences in cerebral hemodynamics and clinical outcomes among male and female patients treated with mechanical thrombectomy (MT) for acute ischemic stroke (AIS) remains unresolved. We aimed to elucidate these differences by employing computed tomography perfusion (CTP) imaging before MT and examining the influence of perfusion deficits on the 90-day functional outcome. Methods: This single-center retrospective analysis involved patients with anterior circulation AIS treated with MT at the Comprehensive Stroke Center, University Hospital, Krakow, from January 2019 to July 2023. We compared male and female patients in terms of baseline characteristics, CTP deficits, hypoperfusion intensity ratio (HIR, defined as T10max/T6max), and complications. The endpoints included the 90-day excellent functional outcome, defined as modified Rankin Score <2, and the 90-day mortality rate. Results: We included 794 patients, of whom 408 were female (51.4%). Female patients had a smaller early infarct volume (median [interquartile range]: 7 mL [0–24.8] vs. 10 mL [0–33], p = 0.004), smaller penumbra volume (77.5 mL [46–117] vs. 99.5 mL [59.8–140], p < 0.001), lower HIR (0.34 [0.16–0.5] vs. 0.37 [0.2–9.53], p = 0.043) and were less likely to achieve an excellent functional outcome (55.6% vs. 66.1%, p = 0.003). For every 10 mL increase in early infarct volume, the odds for achieving an excellent outcome were lower in females (odds ratio [OR]: 0.82 [95% confidence interval: 0.73–0.92]) compared to males (OR: 0.96 [0.88–1.04]), whereas the risk of death was higher for females (OR: 1.25 [1.13–1.39] than for males (OR: 1.05 [0.98–1.14]). Discussion: Despite more favorable cerebral hemodynamic profile, female AIS patients have worse outcomes than their male counterparts. This effect seems to be independently mediated by the more pronounced impact of early infarct volume on the prognosis in female patients. These findings underscore the possible explanatory power arising from sex-specific interpretation of early infarct volume in clinical practice.

Authors: Kirikkaleli Nurdan Ozrecberoglu , Serol Neşe
Published: April 2024

The fear of failure stops students from thinking logically and processing information in mathematics. Creating an appropriate classroom climate based on every student's ability is crucial to overcoming the prejudices associated with mathematics. In this regard, this study aims to create the best classroom climate approach that will increase interest in mathematics and ensure academic success. For this purpose, mathematicians' views on the classroom climate approach and how they create them were discussed by using qualitative techniques. It was considered that teachers participating in this research are working in 9th grade in state high schools affiliated with the Turkish Republic of North Cyprus Ministry of Education, accepting students through examination. The researchers collected teacher views through a semi-structured interview form and analyzed them using context analysis. The findings showed that teachers were in a hurry to teach and generally paid attention to creating a comfortable classroom climate in which students could express their thoughts and opinions. This situation also revealed a lack of adequate classroom climate approach skills among teachers. Therefore, the classroom climate approaches discussed in this study are expected to make a significant contribution to this field by offering solutions to teachers in creating a supportive classroom climate.

Published: April 2024

Mathematics education is looking for innovative methods to foster problem-solving skills in students. This research develops a problem-solving assessment using GeoGebra Classroom, a versatile interactive mathematics software, to revolutionize mathematics formative assessment and improve students' problem-solving skills. This study adopted the analysis, design, development, implementation, and evaluation (ADDIE) instructional design model stages. The design stage created a comprehensive assessment blueprint, incorporating GeoGebra Classroom functions to create interactive problem-solving tasks. Data analysis used both quantitative and qualitative approaches. Qualitative data consisted of feedback and suggestions from assessment experts, mathematicians, and GeoGebra specialists. Meanwhile, quantitative data included expert scores and cognitive tests that measured students' problem-solving abilities. A cognitive post-test was conducted to measure the progress of students' understanding while using the assessment product. The results of the content validity analysis, assessed using Aiken's V, ranged from 0.85 to 0.92, indicating a high level of validity for the problem-solving skills assessment in terms of content and construction. Some revisions were made to the design of the developed media to make it more interactive for students. These findings suggest that we can further use problem-solving questions integrated with GeoGebra Classroom to uncover the problem-solving skills of junior high school students.

Published: April 2024

Environmental risk perception has a long-time travel in the public participation in environmental fields. This perception involves individually socially constructed physical and mental experiences that involve many factors just for knowledge, attitudes, and the culture that develops in society. An individual's understanding of environmental risk provides an overview of an individual's preparedness for appropriate environmental risk strategies and measures. This cross-sectional survey study aims to collect data on the environmental risk perception of Indonesian students. The survey data instrument used in this study is the environmental risk perception scale (ERPS) questionnaire, transformed into Google Forms in the Indonesian language. The target respondents were 1,267 students from 1,300 undergraduate population size of educational study programs in the field of biology who came from various institutions in Indonesia. Sexual category, grade point average (GPA), and university status to explore the perception of the active student environment of prospective biology teachers with various parameters. The results showed several interesting findings: the female sex is more sensitive to environmental risks, academic abilities play a more logical role in environmental risk analysis, and respondents who have taken environmental courses have a higher sensitivity to environmental risk.
EFL teaching approaches in Saudi K–12 education: teacher-centered or student-centered
Authors: Alqahtani Razan Mohammed , Alhamami Munassir
Published: April 2024

This study explores the educational methodologies employed by Saudi English as a foreign language (EFL) teacher, with a specific emphasis on contrasting teacher-centered approachand student-centered approach. Additionally, the research examines the teachers' personal beliefs regarding the most effective approach for implementation in EFL classrooms. To gather data, an online questionnaire was administered to 42 EFL teachers across Saudi K–12 schools in the Southern part of Saudi Arabia. The questionnaire comprised two sections: a demographic information segment and an inquiry into teachers' perspectives and practices. The results of the study showed a dichotomy. While a majority of participants professed that both teacher-centered and student-centered methodologies carry equal importance, a more nuanced picture emerged when examining their claimed practices versus actual classroom behavior. The majority of EFL K–12 instructors in Saudi classrooms leaned towards adopting teacher-centered approaches. These findings hold significant implications for EFL teacher training and professional development courses. This may be due to teachers' lack of confidence in implementing student-centered approaches, the traditional educational culture in Saudi Arabia, or pressure to prepare students for high-stakes exams. The study suggests that teacher education programs should focus on developing teachers' understanding and confidence in using student-centered approaches, and that the Ministry of Education should create a more supportive environment for student-centered teaching approaches.

Learning loss pertains to the decline or regression in knowledge and abilities, as well as setbacks in academic advancement. This phenomenon typically arises from prolonged interruptions or gaps in the pupil’s educational journey. Learning loss can be observed in diverse manifestations due to many factors. One example that can be illustrated is the disruption of formal education due to the COVID-19 pandemic that struck the world in 2019. As a result, this phenomenon has impacted students’ academics, whether at the school level or higher education institutions, especially primary school students, thus causing learning poverty. This scoping review aims to identify the degree of reading literacy among primary school students and to investigate the factors that contribute to the learning losses of primary school students from the reading aspect. Four databases, including Scopus, education resources information center (ERIC), bielefeld academic search engine (BASE) and directory of open access journals (DOAJ), were used in this research, which found 40 articles for eligibility. Only 20 articles are eligible for analysis and reference after the exclusion and inclusion process for data collection. The findings show that learning losses have impacted the education sector, leading to poverty, especially among primary school children.

Published: April 2024

The study's goals were to find out how much culturally responsive leadership headmasters are employed and how many professional learning community (PLC) are set up in small schools. It also looked into the relationship between these two variables by using a questionnaire in a quantitative survey design, which was administered to 546 respondents out of 754 that had been distributed. Descriptive statistics were used to study the level of perception of all variables, and inferential statistics used Pearson’s correlation coefficient to study the relationship between the variables. The findings of the study showed that school headmasters practiced a culturally responsive leadership style, and teachers also participated a lot in PLC. Teacher participation in PLC had a significant relationship with culturally responsive leadership at the 0.05 significance level. The results of the study also showed that culturally responsive leadership accounts for 48.7% of the variance in teacher participation in PLC. This finding greatly suggests that culturally responsive leadership practices are important in contributing to teachers' practices in PLC, which in turn will improve student learning.

Published: April 2024

The role of entrepreneurship in addressing the issue of educated unemployment is well acknowledged, while its specific implications for health professions students remain inadequately explored. This study's main objective is to investigate entrepreneurship education's effect on entrepreneurial intention by considering entrepreneurial self-efficacy as a mediator in students majoring in medical laboratory technology. This quantitative research uses an exploratory approach involving 300 respondents determined through simple random sampling techniques and analyzed using partial least square structural equation model (PLS-SEM). The analysis revealed that entrepreneurship education directly impacts self-efficacy and entrepreneurial intention. Furthermore, entrepreneurial self-efficacy was identified to exert a positive mediating effect between these variables. However, the effect size between the relationships of the research variables is low. Nevertheless, higher education offering health majors can optimize entrepreneurship education by implementing practical learning and field experience to increase confidence and intention in entrepreneurial activities.

The aim of the present study was to compare the effect of different rest intervals between sets of the leg press exercise on total volume, time under tension and ratings of perceived exertion (RPE). Eighteen young women (23.9±3.8 years) performed two experimental sessions, at least 72 hours apart, in a balanced cross-over design. In each session, the participants performed three sets until voluntary exhaustion, with loads that corresponded to 10-12 maximum repetitions, using RI of the two-minute (RI-2) or four-minutes (RI-4). The session performed with RI-4 showed a total volume (∑ repetitions x load) and time under tension (∑ total time duration of the three sets) statistically higher when compared to the RI-2 session (P < 0.05). No statistically significant difference was observed in RPE between sets of both experimental sessions (P < 0.05). The session performed with RI-4 showed a training load (RPE assessed 30 minutes after experimental sessions x duration of the session) statistically higher compared to the session with RI-2 (P < 0.05). The findings of the present study suggest the use of different RI between sets appeared to influence muscle performance and ratings of perceived exertion.

The present study aimed to investigate the professional and academic profile of the faculties of the degree course in Physical Education at the Federal University of Rondônia and related it to their perceptions about the new National Curricular Guidelines - DCNs (2018) for the professional training in Physical Education. Ten of the 12 faculties from the effective staff participated in the study, who answered an online questionnaire prepared by the researchers, containing eight closed and 12 open questions, divided into 3 parts: 1) professional profile; 2) academic profile; and 3) facultie´s perception regarding the new DCNs. The results showed that there is heterogeneity regarding the understanding and acceptance of the differences between the two courses - bachelor and licentiate. In general terms, three characteristic groups emerged from the analysis of the answers to the questionnaire: the first, composed of a group of faculties who understand the difference between the courses, accept them and approve the deliberations of the new DCNs; the second, formed by faculties who have difficulties in distinguishing and accepting the training divided into two courses and therefore do not approve the deliberations of the new DCNs; the third, made up of faculties who show no interest in the subject and thus are unaware of the deliberations of the new DCNs. The results allow us to conclude that a generalist professional formation in the undergraduate course and in fields of knowledge other than Physical Education in the graduate course contributed to the lack of interest and disapproval in relation to the new DCNs. The perspectives to answer to the new delibetations are not opmistic.

Não se decepcionem os que ao compulsarem o presente trabalho, e os outros que por ventura Ihe venham a seguir a esteira, nada encontrem capaz de lembrar as grandes monografias que a intervalos vemos enriquecer a literatura ornitológica, abrindo às vezes perspectivas imprevistas ao estudo cientifico das Aves, ou trançando novos rumos ao progresso dos conhecimentos relacionados com o seu domínio. Verdade é que, inicialmente, prendeu-se ele a ideia, longo tempo acarinhada, de um tratado descritivo das Aves do Brasil, do qual o Catálogo por nos publicado anos atrás seria o arcabouço e alicerce. Mas, a vista da manifesta impossibilidade, criada pelas circunstancias, de levar avante a tentadora empresa, imaginamos imprimir aos nossos trabalhos orientação nova, apresentando em forma singela, e sem grandes compromissos com as praxes rigidamente seguidas pelos especialistas, o compendio da historia natural de alguns grupos, cingindo-nos a sua representação no solo pátrio e escolhendo-os entre os que a experiência. demonstra interessarem mais particularmente, por este ou aquele motivo, os amantes de nossa natureza e os poucos entre nos afeiçoados ao seu estudo. Neste sentido e este esboço da fauna brasileira de Columbidas a primeira tentativa; tentativa ainda assim algo frusta, porque entre os fatores a conspirar contra o seu melhor acabamento esteve sempre à hostilidade constante de estranhas preocupa?6es, e a escassez de tempo para uma aplicação continuada.

Authors: Deppen Juline N. , Ginn Sydney C. , Tang Erica O. , Wang Lanfang , Brockman Maegan L. , Levit Rebecca D.
Published: April 2024

Background

Cellular therapies have been investigated to improve blood flow and prevent amputation in peripheral artery disease with limited efficacy in clinical trials. Alginate‐encapsulated mesenchymal stromal cells (eMSCs) demonstrated improved retention and survival and promoted vascular generation in murine hind limb ischemia through their secretome, but large animal evaluation is necessary for human applicability. We sought to determine the efficacy of eMSCs for peripheral artery disease–induced limb ischemia through assessment in our durable swine hind limb ischemia model.

Methods and Results

Autologous bone marrow eMSCs or empty alginate capsules were intramuscularly injected 2 weeks post–hind limb ischemia establishment (N=4/group). Improvements were quantified for 4 weeks through walkway gait analysis, contrast angiography, blood pressures, fluorescent microsphere perfusion, and muscle morphology and histology. Capsules remained intact with mesenchymal stromal cells retained for 4 weeks. Adenosine‐induced perfusion deficits and muscle atrophy in ischemic limbs were significantly improved by eMSCs versus empty capsules (mean±SD, 1.07±0.19 versus 0.41±0.16,
P
=0.002 for perfusion ratios and 2.79±0.12 versus 1.90±0.62 g/kg,
P
=0.029 for ischemic muscle mass). Force‐ and temporal‐associated walkway parameters normalized (ratio, 0.63±0.35 at week 3 versus 1.02±0.19 preligation;
P
=0.17), and compensatory footfall patterning was diminished in eMSC‐administered swine (12.58±8.46% versus 34.85±15.26%;
P
=0.043). Delivery of eMSCs was associated with trending benefits in collateralization, local neovascularization, and muscle fibrosis. Hypoxia‐cultured porcine mesenchymal stromal cells secreted vascular endothelial growth factor and tissue inhibitor of metalloproteinase 2.

Conclusions

This study demonstrates the promise of the mesenchymal stromal cell secretome at improving peripheral artery disease outcomes and the potential for this novel swine model to serve as a component of the preclinical pipeline for advanced therapies.

Background

Although cardiovascular mortality continued declining from 2000 to 2019, the rate of this decrease decelerated. We aimed to assess the trends and disparities in risk factor control and treatment among US adults with atherosclerotic cardiovascular disease to find potential causes of the deceleration.

Methods and Results

A total of 55 ,021 participants, aged ≥20 years, from the 1999 to 2018 National Health and Nutrition Examination Survey were included, of which 5717 were with atherosclerotic cardiovascular disease. Risk factor control was defined as hemoglobin A1c <7%, blood pressure <140/90 mm Hg, and non–high‐density lipoprotein cholesterol <100 mg/dL. The prevalence of atherosclerotic cardiovascular disease oscillated between 7.3% and 8.9% from 1999 to 2018. A significant increasing trend was observed in the prevalence of diabetes, obesity, heavy alcohol consumption, and self‐reported hypertension within the population with atherosclerotic cardiovascular disease (
P
trend
≤0.001). Non–high‐density lipoprotein cholesterol <100 mg/dL increased from 7.1% in 1999 to 2002 to 15.7% in 2003 to 2006, before plateauing. Blood pressure control (<140/90 mm Hg) increased until 2011 to 2014, but declined to 70.1% in 2015 to 2018 (
P
trend
<0.001,
P
joinpoint
=0.14). Similarly, the proportion of participants achieving hemoglobin A1c control began to decrease after 2006 (
P
joinpoint
=0.05,
P
trend
=0.001). The percentage of participants achieving all 3 targets increased significantly from 4.5% to 18.6% across 1999 to 2018 (
P
trend
=0.02), but the increasing trend decelerated after 2005 to 2006 (
P
joinpoint
<0.001). Striking disparities in risk factor control and medication use persisted between sexes, and between different racial and ethnic populations.

Conclusions

Worsened control of glycemia, blood pressure, obesity, and alcohol consumption, leveled lipid control, and persistent socioeconomic disparities may be contributing factors to the observed deceleration in decreasing cardiovascular mortality trends.

Published: April 2024

Background

Iron deficiency (ID) is a frequent comorbidity in patients with acute (AHF) and chronic heart failure (CHF) associated with morbidity and death. We aimed to better characterize iron homeostasis in patients with heart failure applying different biomarkers and to evaluate the accuracy of current ID definition by the European Society of Cardiology/American College of Cardiology/American Heart Association to indicate tissue iron availability and demand.

Methods and Results

We performed a retrospective cohort study investigating 277 patients with AHF and 476 patients with CHF between February 2021 and May 2022. Patients with AHF had more advanced ID than patients with CHF, reflected by increased soluble transferrin receptor and soluble transferrin receptor–ferritin index, and lower ferritin, serum iron, transferrin saturation, hepcidin, and reticulocyte hemoglobin. Decreased iron availability or increased tissue iron demand, reflected by increased soluble transferrin receptor–ferritin index and decreased reticulocyte hemoglobin, was found in 84.1% (AHF) and 28.0% (CHF) with absolute ID and in 50.0% (AHF) and 10.5% (CHF) with combined ID according to the current European Society of Cardiology/American College of Cardiology/American Heart Association–based ID definition. Low hepcidin expression as an indicator of systemic ID was found in 91.1% (AHF) and 80.4% (CHF) of patients with absolute ID and in 32.3% (AHF) and 18.8% (CHF) of patients with combined ID. ID definitions with higher specificity reduce the need for iron supplementation by 25.5% in patients with AHF and by 65.6% in patients with CHF.

Conclusions

Our results suggest that the current European Society of Cardiology/American College of Cardiology/American Heart Association–based ID definition might overestimate true ID, particularly in CHF. More stringent thresholds for ID could more accurately identify patients with heart failure with reduced tissue iron availability who benefit from intravenous iron supplementation.
Retinal Ischemic Perivascular Lesion Reflects Cerebral Small Vessel Disease Burden in Single Subcortical Infarction
Authors: Kwapong William R. , Yan Yuying , Cao Le , Wang Hang , Ye Chen , Jiang Shuai , Tao Wendan , Wu Bo
Published: April 2024

Background

Retinal ischemic perivascular lesions (RIPLs) are an indicator of ischemia in the middle retina. We aimed to determine the relationship between RIPLs and single subcortical infarction (SSI). We also investigated the differences in cerebral small vessel disease imaging burden between groups with and without RIPLs in SSI.

Methods and Results

In this case–control study, we enrolled 82 patients with SSI and 72 nonstroke controls. All participants underwent magnetic resonance imaging and swept‐source optical coherence tomography/optical coherence tomography angiography. Small vessel disease markers such as lacunes, cerebral microbleeds, white matter hyperintensity, and perivascular spaces were rated on brain imaging. RIPLs were assessed via swept‐source optical coherence tomography. Optical coherence tomography angiography was used to measure the superficial vascular complex and deep vascular complex of the retina. After adjusting for risk factors, the presence of RIPLs was significantly associated with SSI (odds ratio [OR], 1.506 [95% CI, 1.365–1.662],
P
<0.001). Eyes with RIPLs showed lower deep vascular complex density (
P
=0.035) compared with eyes without RIPLs in patients with SSI. After adjusting for vascular risk factors, the presence of RIPLs in patients with SSI was associated with an increased periventricular white matter hyperintensity burden (β=0.414 [95% CI, 0.181–0.647],
P
<0.001) and perivascular spaces‐basal ganglia (β=0.296 [95% CI, 0.079–0.512],
P
=0.008).

Conclusions

RIPLs are associated with SSI independent of underlying risk factors. The relationship between the presence of RIPLs and small vessel disease markers provides evidence that RIPLs might be an additional indicator of cerebral ischemic changes.

Published: April 2024

Background

Despite its approval for acute ischemic stroke >25 years ago, intravenous thrombolysis (IVT) remains underused, with inequities by age, sex, race, ethnicity, and geography. Little is known about IVT rates by insurance status.

Methods and Results

We assessed temporal trends from 2002 to 2015 in IVT for acute ischemic stroke in the Nationwide Inpatient Sample using adjusted, survey
‐
weighted logistic regression. We calculated odds ratios for IVT for each category in 2002 to 2008 (period 1) and 2009 to 2015 (period 2). IVT use for acute ischemic stroke increased from 1.0% in 2002 to 6.8% in 2015 (adjusted annual relative ratio, 1.15). Individuals aged ≥85 years had the most pronounced increase during 2002 to 2015 (adjusted annual relative ratio, 1.18) but were less likely to receive IVT compared with 18‐ to 44‐year‐olds in period 1 (adjusted odds ratio [aOR], 0.23) and period 2 (aOR, 0.36). Women were less likely than men to receive IVT, but the disparity narrowed over time (period 1: aOR, 0.81; period 2: aOR, 0.94). Inequities in IVT resolved for Hispanic individuals in period 2 (aOR, 0.96) but not for Black individuals (period 2: aOR, 0.81). The disparity in IVT for Medicare patients, compared with privately insured patients, lessened over time (period 1: aOR, 0.59; period 2: aOR, 0.75). Patients treated in rural hospitals remained less likely to receive IVT than in urban hospitals; a more dramatic increase in urbanity widened the inequity (period 2, urban nonteaching versus rural: aOR, 2.58, period 2, urban teaching versus rural: aOR, 3.90).

Conclusions

IVT for acute ischemic stroke increased among adults. Despite some encouraging trends, the remaining disparities highlight the need for intensified efforts at addressing inequities.
