RESUMO

The Ala Wai Canal is an artificial waterway in the tourist district of Waikiki in Honolulu, HI. Originally built to collect runoff from industrial, residential, and green spaces dedicated to recreation, the Ala Wai Canal has since experienced potent levels of toxicity due to this runoff entering the watershed and making it hazardous for both marine life and humans at current concentration, including Danio rerio (zebrafish). A community of learners at educations levels from high school to postbaccalaureate from Oahu, HI was connected through the Consortium for Increasing Research and Collaborative Learning Experiences (CIRCLE) distance research program. This team conducted research with an Investigator and team from Mayo Clinic in Rochester, MN, with the Ala Wai Canal as its primary subject. Through CIRCLE, research trainees sent two 32 oz bottles of Ala Wai- acquired water to a partnered laboratory at the Mayo Clinic in which zebrafish embryos were observed at differing concentrations of the sampled water against a variety of developmental and behavioral assays. Research trainees also created atlases of developmental outcomes in zebrafish following exposure to environmental toxins and tables of potential pesticide contaminants to enable the identification of the substances linked to structural defects and enhanced stress during Ala Wai water exposure experiments.

RESUMO

Microscopes are essential for research and education in science. Unlike computers and online learning tools, however, microscopes are not currently a fixed element in K-12 classrooms, due to steep cost, needless complexity, and often requiring a prohibitive level of staff training to effectively deploy. In a collaboration with Area 10 Labs, Integrated Science Education Outreach (InSciEd Out) developed a state-of-the-art alternative microscope, the InSciEdRS View, to reduce the financial barrier, prohibitive per-student cost, unnecessary complexity, and extensive staff training. Utilizing a 1080p camera and a lunchbox-style case, this Wi-Fi- and USB-connectable microscope comes with all necessary components for visualization of microscopic specimens (10 × -50 × magnification). While built to handle the rigors of classroom use, its imaging capability and battery-operation can make it flexible for a laboratory or fieldwork as well. We further highlight here K-12 curricula that we have developed using larval zebrafish to enable teachers, science outreach leaders, and parents to support active hands-on science observations. The InSciEdRS View microscope and the InSciEd Out curricula are readily scalable, translatable, and accessible for traditional and neurodiverse students and integrating these in various settings can be an efficient way to achieve better outcomes in science education.

RESUMO

Gestational Diabetes Mellitus (GDM) has been on the rise for the last two decades along with the growing incidence of obesity. The ubiquitous use of Endocrine-Disrupting Chemicals (EDCs) worldwide has been associated with this increase in GDM incidence. Epigenetic modifications such as DNA methylation, histone acetylation, and methylation have been associated with prenatal exposure to EDCs. EDC exposure can also drive a sustained disruption of the hypothalamus-pituitary-thyroid axis and various other signaling pathways such as thyroid signaling, PPARγ signaling, PI3K-AKT signaling. This disruption leads to impaired glucose metabolism, insulin resistance as well as ß-cell dysfunction, which culminate into GDM. Persistent EDC exposure in pregnant women also increases adipogenesis, which results in gestational weight gain. Importantly, pregnant mothers transfer these EDCs to the fetus via the placenta, thus leading to other pregnancy-associated complications such as intrauterine growth restriction (IUGR), and large for gestational age neonates. Furthermore, this early EDC exposure of the fetus increases the susceptibility of the infant to metabolic diseases in early life. The transgenerational impact of EDCs is also associated with higher vascular tone, cognitive aberrations, and enhanced susceptibility to lifestyle disorders including reproductive health anomalies. The review focuses on the impact of environmental toxins in inducing epigenetic alterations and increasing the susceptibility to metabolic diseases during pregnancy needs to be extensively studied such that interventions can be developed to break this vicious cycle. Furthermore, the use of EDC-associated ExomiRs from the serum of patients can help in the early diagnosis of GDM, thereby leading to triaging of patients based on increasing risk factor of the clinicopathological condition.

RESUMO

Breast cancer is one of the top two reproductive cancers responsible for high rates of morbidity and mortality among women globally. Despite the advancements in the treatment of breast cancer, its early diagnosis remains a challenge. Recent evidence indicates that despite the adroit use of numerous strategies to facilitate rapid and precision-oriented screening of breast cancer at the community level through the use of mammograms, Fine-needle aspiration cytology (FNAC) and biomarker tracking, no strategy has been unequivocally accepted as a gold standard for facilitating rapid screening for disease. This necessitates the need to identify novel strategies for the detection and triage of breast cancer lesions at higher rates of specificity, and sensitivity, whilst taking into account the epidemiologic and social-demographic features of the patients. Recent shreds of evidence indicate that exosomes could be a robust source of biomaterial for the rapid screening of breast cancer due to their high stability and their presence in body fluids. Increasing evidence indicates that the Exosomal microRNAs- play a significant role in modifying the tumour microenvironment of breast cancers, thereby potentially aiding in the proliferation, invasion and metastasis of breast cancer. In this review, we summarize the role of ExomiRs in the tumour microenvironment in breast cancer. These ExomiRs can also be used as candidate biomarkers for facilitating rapid screening and triaging of breast cancer patients for clinical intervention.

RESUMO

BACKGROUND: Mental health care is a top clinical concern for modern Puerto Rico, especially given a dramatically changing economic landscape paired with recurrent natural disasters. Youth are particularly at-risk due to long-term impacts of toxic stress and adverse childhood experiences on health and development. OBJECTIVES: Here we present a novel clinician-community-educator-scientist partnership to address Puerto Rican youth mental well-being and wellness. We deployed pilot health workshops within the Boys & Girls Clubs of Puerto Rico to build youth mental health conceptual understanding and competencies in stress recognition and management. The work in progress herein evaluates acceptability and feasibility of our curricular model. METHODS: Dialogue with community stakeholders guided curricular design of workshops for youth ages 6 to 13 and older. Prior to implementation, educators and volunteers attended a 1-day training on educational strategies. Workshop success was evaluated using qualitative approaches (i.e., narrative feedback, educator and volunteer reflections, youth Talking Drawings) to assess youth engagement, youth conceptual health understanding, and educator/volunteer impressions of feasibility and impact. RESULTS: Initial findings indicate high acceptability and feasibility of our curricular model. Youth engagement and enthusiasm were noted in educator feedback and continue to be sustained post-workshop. Preliminary analysis shows accompanying increases in youth conceptual mental health understanding, particularly for 6- to 12-year-olds in recognition of stress and healthy coping mechanisms. Reciprocal gains were observed for volunteers. CONCLUSIONS: Activities have evolved into a formal partnership called Semilla, which features expanded analysis of mental well-being and wellness outcomes. Our collaborative model continues to engage Puerto Rican youth in the science of their well-being.

RESUMO

COVID-19 continues to alter daily life around the globe. Education is particularly affected by shifts to distance learning. This change has poignant effects on all aspects of academic life, including the consequence of increased mental stress reported specifically for students. COVID-19 cancellations of many summer fellowships and internships for undergraduates across the country increased students' uncertainty about their educational opportunities and careers. When the pandemic necessitated elimination of on-campus programming at Mayo Clinic, a new program was developed for remote delivery. Summer Foundations in Research (SFIR) was drafted around 4 aims: 1) support the academic trajectory gap in research science created by COVID-19; 2) build sustainable scientific relationships with mentors, peers, and the community; 3) create opportunities for participants to share and address concerns with their own experiences in the pandemic; and 4) provide support for individual wellbeing. SFIR included research training, but also training in communication through generative Dialogue and resilience through Amit Sood's SMART program. 170 participants were followed for outcomes in these spaces. Knowledge of and interest in careers involving biomedical research rose significantly following SFIR. Participants' mean confidence levels in 12 Key areas of research rose between 0.08 to 1.32 points on a 7-point scale. The strongest gains in mean confidence levels were seen in designing a study and collaborating with others. SFIR participants demonstrated gains in perceived happiness, and measured resilience and a reduction in stress. Participants' qualitative responses indicated exceptionally positive mentor relationships and specific benefit of both the SMART program and Dialogue.

RESUMO

When COVID-19 caused worldwide cancellations of summer research immersion programs in 2020, Mayo Clinic rallied to create an alternate virtual experience called Summer Foundations in Research (SFIR). SFIR was designed not only to ensure the continuance of science pathways training for undergraduate scientists but also to support undergraduate mental wellbeing, given the known pandemic stressors. A total of 170 participants took part in the program and were surveyed pre-post for outcomes in biomedical research career knowledge, biomedical research career interest, research skills confidence, and three dimensions of mental wellbeing. Knowledge of and interest in careers involving biomedical research rose significantly following participation in SFIR. The participants' mean research skills confidence also rose between 0.08 and 1.32 points on a 7-point scale across 12 items from the Clinical Research Appraisal Inventory. Success in science pathways support was accompanied by positive shifts in participant mental wellbeing. Measurable decreases in stress (Perceived Stress Scale, p < 0.0001) accompanied gains in resilience (Brief Resilience Scale, p < 0.0001) and life satisfaction (Satisfaction with Life Scale, p = 0.0005). Collectively, the data suggest that core objectives of traditional in-person summer research programming can be accomplished virtually and that these programs can simultaneously impact student wellbeing. This theoretical framework is particularly salient during COVID-19, but the increased accessibility of virtual programs such as SFIR can continue to bolster science education pathways long after the pandemic is gone.

RESUMO

To adapt to the increasingly technology-driven environment of modern K-12 education Integrated Science Education Outreach (InSciEd Out) digitized an extensive professional development curriculum library that forms the core experience for teachers joining the program. In previous years the curriculum had been delivered solely in print form. The goals of this conversion were to better employ technology in the teacher training experience that mirrored best practice in their K-12 classrooms and to provide a more scalable product for InSciEd Out. The digitized professional development curriculum was delivered using Google Classroom accessed by teachers with Chromebooks. The digitization measurably improved flexibility for engagement in scientific experimentation and granted immediate access to course feedback for the program. Teachers who participated rated the course positively in general and specifically reported increased self-efficacy in technology use both in the internship and in the classroom.

RESUMO

As the population of K-12 English language learners (ELLs) grows, teachers are challenged to employ strategies that efficiently promote content-learning and language-learning. This paper reports an action research project investigating the effects of three consecutive instructional interventions on student language production at a suburban elementary school. Teachers identified a problem of practice, consulted scholarship for intervention design, and conducted collaborative action research in science, mathematics, and social studies classes. Participants included grades 2-4 ELL and non-ELL students. Data was collected using a modified version of Soto's ELL Shadowing Protocol Form (2012), monitoring frequency of student-speaking, teacher-speaking, student-listening, and on- and off-task behavior. Quantitative analyses found that utilization of message abundancy, 'tasks that require talk,' and stretched language positively impacted student language production and on-task behavior. Statistically significant differences were found in mathematics language production for both ELL (Intervention 1 to 2 p=0.0028; Overall p=0.0023) and non-ELL students (Intervention 1 to 2 p<0.0001) and in task-oriented behavior in science and social studies for non-ELL students (Baseline to Intervention 1 and Overall p<0.0001). Differences between ELL and non-ELL students for both language production and on-task behavior narrowed with time, suggesting that the interventions employed equalized student behaviors.

RESUMO

Influenza is a global problem infecting 5-10% of adults and 20-30% of children annually. Non-pharmaceutical interventions (NPIs) are attractive approaches to complement vaccination in the prevention and reduction of influenza. Strong cyclical reduction of absolute humidity has been associated with influenza outbreaks in temperate climates. This study tested the hypothesis that raising absolute humidity above seasonal lows would impact influenza virus survival and transmission in a key source of influenza virus distribution, a community school. Air samples and objects handled by students (e.g. blocks and markers) were collected from preschool classrooms. All samples were processed and PCR used to determine the presence of influenza virus and its amount. Additionally samples were tested for their ability to infect cells in cultures. We observed a significant reduction (p < 0.05) in the total number of influenza A virus positive samples (air and fomite) and viral genome copies upon humidification as compared to control rooms. This suggests the future potential of artificial humidification as a possible strategy to control influenza outbreaks in temperate climates. There were 2.3 times as many ILI cases in the control rooms compared to the humidified rooms, and whether there is a causal relationship, and its direction between the number of cases and levels of influenza virus in the rooms is not known. Additional research is required, but this is the first prospective study suggesting that exogenous humidification could serve as a scalable NPI for influenza or other viral outbreaks.

RESUMO

BACKGROUND: Mental illness contributes substantially to global disease burden, particularly when illness onset occurs during youth and help-seeking is delayed and/or limited. Yet, few mental health promotion interventions target youth, particularly those with or at high risk of developing mental illness ("at-risk" youth). Community-based translational research has the capacity to identify and intervene upon barriers to positive health outcomes. This is especially important for integrated care in at-risk youth populations. METHODS: Here the Integrated Science Education Outreach (InSciEd Out) program delivered a novel school-based anti-stigma intervention in mental health to a cohort of seventh and eighth grade at-risk students. These students were assessed for changes in mental health knowledge, stigmatization, and help-seeking intentions via a classroom activity, surveys, and teacher interviews. Descriptive statistics and Cohen's d effect sizes were employed to assess pre-post changes. Inferential statistical analyses were also conducted on pilot results to provide a benchmark to inform future studies. RESULTS: Elimination of mental health misconceptions (substance weakness p = 0.00; recovery p = 0.05; prevention p = 0.05; violent p = 0.05) was accompanied by slight gains in mental health literacy (d = 0.18) and small to medium improvements in help-seeking intentions (anxiety d = 0.24; depression d = 0.48; substance d = 0.43; psychosis d = 0.53). Within this particular cohort of students, stigma was exceptionally low at baseline and remained largely unchanged. Teacher narratives revealed positive teacher views of programming, increased student openness to talk about mental illness, and higher peer and self-acceptance of mental health diagnoses and help-seeking. CONCLUSIONS: Curricular-based efforts focused on mental illness in an alternative school setting are feasible and integrated well into general curricula under the InSciEd Out framework. Preliminary data suggest the existence of unique help-seeking barriers in at-risk youth. Increased focus upon community-based programming has potential to bridge gaps in translation, bringing this critical population to clinical care in pursuit of improved mental health for all.

RESUMO

Interest among the zebrafish community in education and science accessibility for all ages has increased. At the 8th Annual Zebrafish Disease Models Conference (ZDM8), a specifically designed session enabled professional scientists, educators, and students to have a venue to present their science, discuss ideas in education, and partner to navigate a scientific meeting as an educational experience. This meeting report describes the format of the Platform Session as well as challenges and future plans to leverage impact of conferences on the local communities.

RESUMO

The primary and secondary learning years shape development of scientific interest and skills required for science literacy, presenting a critical timeline target for science education intervention. Although many initiatives exist to target this timeframe, the modern classroom belies easy scientific investigation. Numerous initiatives often run simultaneously in a given classroom, creating limited capacity for variable control. Consequently, there is a dearth of high-quality and meaningful data in education sciences that exacerbates the general segregation of education research from practice. Many science reform programmes go unmeasured. The limited number that is researched often report strictly qualitative results or stop short of statistically significant quantitative investigation. Lack of high-resolution data restricts the ability to make informed policy changes and precludes attainment of "evidence-based education". Here, we demonstrate 5-year efficacy of a novel, inquiry-based primary and secondary science reform programme Integrated Science Education Outreach (InSciEd Out). Five years of data over three cohorts of matched students from US grades 5-8 show maintained gains in science fair and honours biology election, as well as improved performance on Minnesota state standardized science testing. Detailed value-added analyses further reveal InSciEd Out-correlated gains in partnership-focused areas of life sciences, and history and nature of science. These analyses provide evidence that scientifically rigorous evaluation demonstrating relevant programme efficacy is indeed achievable in education science. Our results support the premise that the InSciEd Out programme is a scalable intervention capable of primary and secondary science education reform. The programme substantively builds upon prior efforts in the field. Although InSciEd Out deploys novel approaches and tools, the broad lessons learned from this programme are readily translatable to other contemporary efforts cultivating science literacy for all.

RESUMO

Despite the fact infectious diseases can spread readily in grade schools, few studies have explored prevention in this setting. Additionally, we lack valid tools for students to self-report knowledge, attitudes, and behaviors. As part of an ongoing study of a curriculum intervention to promote healthy behaviors, we developed and evaluated age-appropriate surveys to determine students' understanding of influenza prevention. Surveys were adapted from adolescent and adult influenza surveys and administered to students in grades 2-5 (ages 7-11) at two Rochester public schools. We assessed student understanding by analyzing percent repeatability of 20 survey questions and compared percent "don't know" (DK) responses across grades, gender, and race. Questions thought to be ambiguous after early survey administration were investigated in student focus groups, modified as appropriate, and reassessed. The response rate across all surveys was >87%. Survey questions were well understood; 16 of 20 questions demonstrated strong pre/post repeatability (>70%). Only 1 question showed an increase in DK response for higher grades (p < .0001). Statistical analysis and qualitative feedback led to modification of 3 survey questions and improved measures of understanding in the final survey administration. Grade-school students' knowledge, attitudes and behavior toward influenza prevention can be assessed using surveys. Quantitative and qualitative analysis may be used to assess participant understanding and refine survey development for pediatric survey instruments. These methods may be used to assess the repeatability and validity of surveys to assess the impact of health education interventions in young children.

RESUMO

BACKGROUND: Low absolute humidity (AH) has been associated with increased influenza virus survival and transmissibility and the onset of seasonal influenza outbreaks. Humidification of indoor environments may mitigate viral transmission and may be an important control strategy, particularly in schools where viral transmission is common and contributes to the spread of influenza in communities. However, the variability and predictors of AH in the indoor school environment and the feasibility of classroom humidification to levels that could decrease viral survival have not been studied. METHODS: Automated sensors were used to measure temperature, humidity and CO2 levels in two Minnesota grade schools without central humidification during two successive winters. Outdoor AH measurements were derived from the North American Land Data Assimilation System. Variability in indoor AH within classrooms, between classrooms in the same school, and between schools was assessed using concordance correlation coefficients (CCC). Predictors of indoor AH were examined using time-series Auto-Regressive Conditional Heteroskedasticity models. Classroom humidifiers were used when school was not in session to assess the feasibility of increasing indoor AH to levels associated with decreased influenza virus survival, as projected from previously published animal experiments. RESULTS: AH varied little within classrooms (CCC >0.90) but was more variable between classrooms in the same school (CCC 0.81 for School 1, 0.88 for School 2) and between schools (CCC 0.81). Indoor AH varied widely during the winter (range 2.60 to 10.34 millibars [mb]) and was strongly associated with changes in outdoor AH (p < 0.001). Changes in indoor AH on school weekdays were strongly associated with CO2 levels (p < 0.001). Over 4 hours, classroom humidifiers increased indoor AH by 4 mb, an increase sufficient to decrease projected 1-hour virus survival by an absolute value of 30% during winter months. CONCLUSIONS: During winter, indoor AH in non-humidified grade schools varies substantially and often to levels that are very low. Indoor results are predicted by outdoor AH over a season and CO2 levels (which likely reflects human activity) during individual school days. Classroom humidification may be a feasible approach to increase indoor AH to levels that may decrease influenza virus survival and transmission.

RESUMO

Integrated Science Education Outreach (InSciEd Out) is a collaboration formed between Mayo Clinic, Winona State University, and Rochester Public Schools (MN) with the shared vision of achieving excellence in science education. InSciEd Out employs an equitable partnership model between scientists, teachers, education researchers, and the community. Teams of teachers from all disciplines within a single school experience cutting-edge science using the zebrafish model system, as well as current pedagogical methods, during a summer internship at the Mayo Clinic. Within the internship, the teachers produce new curriculum that directly addresses opportunities for science education improvement at their own school. Zebrafish are introduced within the new curriculum to support a living model of the practice of science. Following partnership with the InSciEd Out program and 2 years of implementation in the classroom, teacher-interns from a K-8 public school reported access to local scientific technology and expertise they had not previously recognized. Teachers also reported improved integration of other disciplines into the scientific curriculum and a flow of concepts vertically from K through 8. Students more than doubled selection of an Honors science track in high school to nearly 90%. 98% of students who took the Minnesota Comprehensive Assessments in their 5(th) and 8(th) grade year (a span that includes 2 years of InSciEd Out) showed medium or high growth in science proficiency. These metrics indicate that cooperation between educators and scientists can result in positive change in student science proficiency and demonstrate that a higher expectation in science education can be achieved in US public schools.

RESUMO

Many assays are used in animal model systems to measure specific human disease-related behaviors. The use of both adult and larval zebrafish as a behavioral model is gaining popularity. As this work progresses and potentially translates into new treatments, we must do our best to improve the sensitivity of these assays by reducing confounding factors. Scientists who use the mouse model system have demonstrated that sex and age can influence a number of behaviors. As a community, they have moved to report the age and sex of all animals used in their studies. Zebrafish work does not yet carry the same mandate. In this study, we evaluated sex and age differences in locomotion behavior. We found that age was a significant factor in locomotion, as was sex within a given age group. In short, as zebrafish age, they appear to show less base level locomotion. With regard to sex, younger (10 months) zebrafish showed more locomotion in males, while older zebrafish (22 months) showed more movement in females. These findings have led us to suggest that those using the zebrafish for behavioral studies control for age and sex within their experimental design and report these descriptors in their methods.
