Inclusive Approaches for Measuring Demographics of Underrepresented Populations in STEM and Biomedical Research Training Programs.

As federal strategic plans prioritize increasing diversity within the biomedical workforce, and STEM training and outreach programs seek to recruit and retain students from historically underrepresented populations, there is a need for interrogation of traditional demographic descriptors and careful consideration of best practices for obtaining demographic data. To accelerate this work, equity-focused researchers and leaders from STEM programs convened to examine approaches for measuring demographic variables. Gender, race/ethnicity, disability, and disadvantaged background were prioritized given their focus by federal funding agencies.

Novel recruitment approaches and operational results for a statewide population Cohort for cancer research: The Healthy Oregon Project.

Background: Cancer health research relies on large-scale cohorts to derive generalizable results for different populations. While traditional epidemiological cohorts often use costly random sampling or self-motivated, preselected groups, a shift toward health system-based cohorts has emerged. However, such cohorts depend on participants remaining within a single system.

Population screening shows risk of inherited cancer and familial hypercholesterolemia in Oregon.

The Healthy Oregon Project (HOP) is a statewide effort that aims to build a large research repository and influence the health of Oregonians through providing no-cost genetic screening to participants for a next-generation sequencing 32-gene panel comprising genes related to inherited cancers and familial hypercholesterolemia. This type of unbiased population screening can detect at-risk individuals who may otherwise be missed by conventional medical approaches. However, challenges exist for this type of high-throughput testing in an academic setting, including developing a low-cost high-efficiency test and scaling up the clinical laboratory for processing large numbers of samples.

Interprofessional Near-Peer Mentoring Teams Enhance Cancer Research Training: Sustainable Approaches for Biomedical Workforce Development of Historically Underrepresented Students.

A cancer research training program explored different approaches for staffing their in-person and virtual programs for high school students. The inclusion of undergraduate near-peer mentors had a universal benefit when implemented across in-person and virtual training programs of one- and ten-week durations. Benefits are described for four stakeholder groups: the high school trainees, program staff, scientist partners, and peer mentors themselves.

Knight Scholars Program: A Tiered Three-Year Mentored Training Program for Urban and Rural High School High School Students Increases Interest and Self-Efficacy in Interprofessional Cancer Research.

Cancer research training programs build our future biomedical workforce. Training is often centered for students residing close to research institutions, making access more challenging for rural students. A cancer research training program was developed for high school students residing in five geographical regions across Oregon.

A Non-Randomized Trial Investigating the Impact of Brown Rice Consumption on Gut Microbiota, Attention, and Short-Term Working Memory in Thai School-Aged Children.

While dietary fiber has been shown to influence the composition of gut microbiota and cognitive function in adults, much less is known about the fiber-microbiome-cognition association in children. We profiled gut microbiota using quantitative PCR (qPCR) and evaluated cognitive function using the Corsi block-tapping test (CBT) and the psychomotor vigilance test (PVT) before, during, and after the dietary intervention of 127 school-aged children in northern Thailand. While we found that Sinlek rice (SLR) consumption did not significantly alter the abundance of gut microbiota or the cognitive performance of school-aged children, we did find age to be associated with variations in both the gut microbiota profiles and cognitive outcomes.

Approaches for Measuring Inclusive Demographics Across Youth Enjoy Science Cancer Research Training Programs.

The National Cancer Institute's (NCI) Youth Enjoy Science Program (YES) funds initiatives to support the cancer research training and career ambitions of middle school through undergraduate students from populations underrepresented in the biomedical sciences. The program has funded 16 institutions nationally as of January 2022. Given the program's focus on increasing diversity within the cancer research workforce, demographic characteristics of YES trainees provide essential information about the populations being served and program effectiveness.

A low-cost, open-source centrifuge adaptor for separating large volume clinical blood samples.

Blood plasma separation is a prerequisite in numerous biomedical assays involving low abundance plasma-borne biomarkers and thus is the fundamental step before many bioanalytical steps. High-capacity refrigerated centrifuges, which have the advantage of handling large volumes of blood samples, are widely utilized, but they are bulky, non-transportable, and prohibitively expensive for low-resource settings, with prices starting at $1,500. On the other hand, there are low-cost commercial and open-source micro-centrifuges available, but they are incapable of handling typical clinical amounts of blood samples (2-10mL).

The fecal microbiota of Thai school-aged children associated with demographic factors and diet.

Background: Birth delivery method and breastfeeding practices contribute to microbiota colonization. Other factors including diet and demographic factors structure the gut microbiome assembly and diversity through childhood development. The exploration of these factors, especially in Southeast Asian children, remains limited.

Increased Chance of Live Birth Following Use of Connected Ovulation Test System: Outcome Results from a Randomized Controlled Trial.

Natural conception requires intercourse to occur during the fertile window of a woman's menstrual cycle. This follow-up study of a randomized controlled trial aimed to determine whether the use of a urine ovulation test system, which tracks elevations in both luteinizing hormone and an estradiol metabolite, increases the likelihood of live births in women trying to conceive. In the home-based trial, 844 women aged 18-40 years who were attempting to conceive were randomized 1:1 into the test or control arms.

Period tracker applications: What menstrual cycle information are they giving women?

Background: Period tracking applications (apps) allow women to track their menstrual cycles and receive a prediction for their period dates. The majority of apps also provide predictions of ovulation day and the fertile window. Research indicates apps are basing predictions on assuming women undergo a textbook 28-day cycle with ovulation occurring on day 14 and a fertile window between days 10 and 16.

Supporting Biomedical Research Training for Historically Underrepresented Undergraduates Using Interprofessional, Nonformal Education Structures.

Research experience provides critical training for new biomedical research scientists. Students from underrepresented populations studying science, technology, engineering, and mathematics (STEM) are increasingly recruited into research pathways to diversify STEM fields. However, support structures outside of research settings designed to help these students navigate biomedical research pathways are not always available; nor are program support components outside the context of laboratory technical skills training and formal mentorship well understood.

Public perception of predictive cancer genetic testing and research in Oregon.

The potential for using widespread genetic testing to inform health care has become a viable option, particularly for heritable cancers. Yet, little is known about how to effectively communicate the benefits and risks of both personal genetic testing and participation in biorepositories that aid scientific advancements. Nationwide efforts are engaging communities in large genetic studies to better estimate the population-wide prevalence of heritable cancers but have been met with hesitance or declination to participate in some communities.

Jointly modelling longitudinally measured urinary human chorionic gonadotrophin and early pregnancy outcomes.

Human chorionic gonadotrophin (hCG) is largely used to confirm pregnancy. Yet evidence shows that longitudinal hCG profiles are distinguishable between healthy and failing pregnancies. We retrospectively fitted a joint longitudinal-survival model to data from 127 (85 healthy and 42 failing pregnancies) US women, aged 18-45, who were attempting to conceive, to quantify the association between longitudinally measured urinary hCG and early miscarriage.

Peri-implantation urinary hormone monitoring distinguishes between types of first-trimester spontaneous pregnancy loss.

Background: Lutenising hormone (LH) and human chorionic gonadotropin (hCG) hormone are useful biochemical markers to indicate ovulation and embryonic implantation, respectively. We explored "point-of-care" LH and hCG testing using a digital home-testing device in a cohort trying to conceive.

Objective: To determine conception and spontaneous pregnancy loss rates, and to assess whether trends in LH-hCG interval which are known to be associated with pregnancy viability could be identified with point-of-care testing.

Opposing effects of impulsivity and mindset on sources of science self-efficacy and STEM interest in adolescents.

Impulsivity has been linked to academic performance in the context of Attention Deficit Hyperactivity Disorder, though its influence on a wider spectrum of students remains largely unexplored, particularly in the context of STEM learning (i.e. science, technology, engineering, and math).

Thai adaptation and reliability of three versions of the Barratt Impulsiveness Scale (BIS 11, BIS-15, and BIS-Brief).

Long, short, and brief versions of the Barratt Impulsiveness scale (BIS-11, BIS-15, and BIS-Brief) were tested in an adult Thai population. The BIS-11T and BIS-15T were translated, back-translated, and administered to a non-clinical population (n = 305) of native Thai speakers who returned 2 weeks later for re-test. BIS-Brief-T psychometrics were calculated post-hoc.

Can apps and calendar methods predict ovulation with accuracy?

Objective: The accuracy of prediction of ovulation by cycle apps and published calendar methods was determined by comparing to true probability of ovulation.

Methods: A total of 949 volunteers collected urine samples for one entire menstrual cycle. Luteinizing hormone was measured to assign surge day, enabling probability of ovulation to be determined across different cycle lengths.

Analysis of urinary human chorionic gonadotrophin concentrations in normal and failing pregnancies using longitudinal, Cox proportional hazards and two-stage modelling.

Background Human chorionic gonadotrophin is a marker of early pregnancy. This study sought to determine the possibility of being able to distinguish between healthy and failing pregnancies by utilizing patient-associated risk factors and daily urinary human chorionic gonadotrophin concentrations. Methods Data were from a study that collected daily early morning urine samples from women trying to conceive (n = 1505); 250 of whom became pregnant.

Experiential Learning Through Participatory Action Research in Public Health Supports Community-Based Training of Future Health Professionals.

Engaging community members in research can help cultivate effective partnerships while providing experiential training and continuing education opportunities. Several studies have involved communities in this way, though many have been small in the scale of community involvement or have included little detail of the institutional review board process by which community members became approved researchers in the study. This article presents findings on an evaluation of the training procedures and experiences of 703 first-time community-based volunteer researchers who were recruited in their communities and trained on-site to enroll research participants, collect data, and provide individualized consultation of results at travelling health education and research fairs.

Epigenetics: A new science for middle school - and why you should teach it.

Epigenetics is a new field of science that underscores why your students' choices matter. Epigenetics describes how the environment and your experiences can control the rate at which your DNA works. Instead of changing the bases of the DNA, which would be a mutation, the environment that you experience can make chemical tags that are placed on your DNA.
