17. Voices of the Students: Adolescent Well-Being and Social Interactions during the Emergent Shift to Online Learning Environments

Author

Cockerham, Deborah, Lin, Lin, Ndolo, Sharon, and Schwartz, Marc

Abstract

Health and safety concerns during the COVID-19 pandemic required many face-to-face United States schools to suddenly shut their doors, moving classes to virtual learning environments. Amidst concerns of technology overuse, adolescents across the country saw dramatic increases in both personal screen time use and social isolation as they learned to navigate online schooling. Understanding the impact of the pandemic-related shutdowns upon adolescent well-being, learning, and social life is critical for designing effective online learning experiences, but research provides few insights from the adolescent perspective. This mixed methods study works to fill this gap by investigating adolescent needs and perceptions during the pandemic. The main questions asked are: (1) To what extent does adolescent well-being during the pandemic differ from pre-pandemic well-being?; (2) What factors do adolescents view as influences upon their learning during the imposed shift to online schooling?; and (3) What social changes and concerns do adolescents report during the pandemic? Twenty-one adolescents completed Likert scale surveys and participated in semi-structured one-to-one interviews. Results showed a significant decrease in positive affect and a significant increase in negative affect during the pandemic, suggesting a decline in well-being. The majority of participants reported high distractibility and noted the lure of entertaining technology, but also described their smartphones as "connecting" and "necessary". Social interactions were a priority for all participants, but participants agreed that opportunities for social connectedness in online education were limited. The challenges of online learning, the importance of identifying and responding to student needs, and suggested strategies for online education are discussed.

21. Predicting relapse in acute lymphoblastic leukemia.

Author

Schwartz, Marc S. and Muffly, Lori S.

Abstract

AbstractOutcomes in adult and pediatric patients with acute lymphoblastic leukemia (ALL) have improved over successive generations due to rigorously conducted clinical trials and incorporation of novel therapeutic agents. Despite these advances, approximately 20% of high-risk pediatric patients and 50% of adults with ALL will fail to achieve long-term remission with frontline chemotherapy protocols, mostly due to relapse. The ability to predict which patients with ALL are more likely to relapse allows for early intensification of therapy and/or incorporation of novel immunotherapies with the goal of relapse prevention. In this review, we outline the most robust clinical predictors of relapse in ALL with a focus on measurable residual disease (MRD) and genomics. We also discuss application of these prognostic tools in different clinical settings including frontline treatment, pre-/post-allogeneic stem cell transplant, and pre-/post-Chimeric Antigen Receptor T-cell therapy.

27. White blood cell count nadir to zero following intensive chemotherapy as a predictive factor for patients with acute myeloid leukemia.

Author

Abstract

Predictors for response to intensive therapy in AML have focused on baseline factors: percent leukemic blasts in marrow, cytogenetic/molecular genetic abnormalities, and presence of secondary AML. Non-baseline dynamic factors, occurring after induction but before response, may be useful for decisions related to salvage chemotherapy. We hypothesized white blood cell (WBC) count nadir after induction may be a real time indicator of treatment efficacy. We also examined whether time to stem cell transplant (SCT) or baseline molecular genetic abnormalities are associated with a low nadir. Data showed WBC nadir = 0 was a negative predictor for response to intensive induction and was correlated with reduced overall survival and progression free survival. Patients with WBC nadir = 0 did not have a significantly longer time to SCT, and none of the mutations increased the likelihood of reaching WBC nadir = 0. WBC nadir may be a useful real-time monitor in AML patients receiving intensive induction chemotherapy. [ABSTRACT FROM AUTHOR]

Al'Khafaji, Aziz M., Smith, Jonathan T., Garimella, Kiran V., Babadi, Mehrtash, Popic, Victoria, Sade-Feldman, Moshe, Gatzen, Michael, Sarkizova, Siranush, Schwartz, Marc A., Blaum, Emily M., Day, Allyson, Costello, Maura, Bowers, Tera, Gabriel, Stacey, Banks, Eric, Philippakis, Anthony A., Boland, Genevieve M., Blainey, Paul C., and Hacohen, Nir

Abstract

Full-length RNA-sequencing methods using long-read technologies can capture complete transcript isoforms, but their throughput is limited. We introduce multiplexed arrays isoform sequencing (MAS-ISO-seq), a technique for programmably concatenating complementary DNAs (cDNAs) into molecules optimal for long-read sequencing, increasing the throughput >15-fold to nearly 40 million cDNA reads per run on the Sequel IIe sequencer. When applied to single-cell RNA sequencing of tumor-infiltrating T cells, MAS-ISO-seq demonstrated a 12- to 32-fold increase in the discovery of differentially spliced genes. Programmable concatenation of cDNA molecules increases the throughput of PacBio sequencing about 15-fold. [ABSTRACT FROM AUTHOR]

31. Confronting the Need for Conceptual Change in Pre-Service Science Education

Author

Schwartz, Marc S., Shapiro, Irwin I., and Gregory, Bruce

Abstract

During a five-year period the authors taught over 100 students in a graduate course (The Nature of Science) counting toward teacher certification at the Harvard Graduate School of Education. Despite the fact that students had undergraduate degrees in the sciences, most of them found the application of models in science challenging and the epistemological consequences unsettling. Moreover, students found it especially difficult to use a model to correctly generate predictions, which was starkly illustrated with the application of Archimedes' principle during our unit on floating and sinking. We examine the deceptive belief that student success with algorithms and word problems leads to conceptual understanding as well as the conceptual change necessary to understand the relationship between evidence and inference as explored in the nature of science. Considering the apparently strong science backgrounds of our students, we doubt that typical pre-college students can achieve the goals described in the National Science Education Standards in the short time typically allotted for their science studies. We explore the issues students face in "understanding" science as well as the impact of science education on students and teachers, and implications for policy makers and pre-service programs.

37. Divergent Views: Teacher and Professor Perceptions about Pre-College Factors that Influence College Science Success

Author

Schwartz, Marc S., Hazari, Zahra, and Sadler, Philip M.

Abstract

Interview data from secondary and postsecondary science instructors explored their in-depth views on preparing students for college science. Professors expressed a high level of consensus concerning two factors: general student skills and mathematics preparation. Teachers, who expressed lower levels of consensus, did agree on the importance of mathematics, but also highlighted a variety of factors that promote active pedagogy in the classroom as well as the importance of technology, textbooks, other materials, and assessments. Given this divergence, the authors explored the research supporting the value of these factors as well as highlighted possible strategies for narrowing the gap. (Contains 5 figures and 3 tables.)

Abstract

Purpose: Telegenetics has become the predominant mode of cancer genetic counseling during the COVID-19 pandemic. We sought to identify potential patient-level contraindicators for telegenetic genetic counseling. Methods: We analyzed post-counseling (pre-result disclosure) follow-up data from a randomized noninferiority trial of a telephone genetic counseling versus usual care genetic counseling. Among 669 randomized participants, 600 completed pre-test counseling and 568 completed a 2-week follow-up assessment before receiving test results. In this analysis, we focused on genetic counseling outcomes (knowledge, decisional conflict, and distress). In multivariate models controlling for bivariate predictors of these outcomes, we tested our a priori hypotheses that pre-counseling numeracy, perceived stress, and race/ethnicity would moderate the outcomes of telephone genetic counseling versus usual care. Results: Only numeracy significantly moderated associations between mode of genetic counseling and outcomes. Higher numeracy was associated with higher post-counseling knowledge following telephone genetic counseling (p < 0.001), but not usual care (p = 0.450). Higher numeracy was also associated with lower distress following telephone genetic counseling (p = 0.009) but not usual care (p = 0.16). Neither perceived stress nor race/ethnicity exhibited differential impacts on telephone genetic counseling versus usual care (p s > 0.20). Conclusion: Although high numeracy was associated with higher levels of knowledge following telegenetic counseling, we did not identify any clinically significant patient-level contraindicators for telegenetic counseling. These results lend further confidence to the broad use of telegenetics. [ABSTRACT FROM AUTHOR]

Abstract

Background: Recently recognized as a distinct entity, a myxoid glioneuronal tumor (MGNT) is a rare, low-grade central nervous system tumor. MGNTs are commonly located at the septumpellucidum or in the third ventricle, increasing the likelihood of tumor or treatment-related damage to adjacent structures critical formemory, such as the fornix. Though there have been a handful of case reports of neurosurgical and oncological outcomes of MGNTs, memory outcomes following resection of MGNTs adjacent to the fornix have not been previously reported. Methods: We present a case of a high functioning female for whom an MRI revealed an incidental finding of an intraventricular tumor adjacent to the fornix bilaterally. The patient underwent resection of the tumor followed by MRI surveillance without additional oncologic intervention. Due to reported cognitive problems, the patient was referred for serial neuropsychological evaluations. Results: Post-operative MRI following resection revealed cytotoxic edema followed by selective, progressive atrophy of the bilateral anterior fornices. Post-surgically, the patient developed an isolated verbal memory impairment, which persisted one-year post resection with minimal improvement. The memory impairment impacted the patient's everyday functioning, including the ability to work in a cognitively demanding job. Conclusion: This unique case demonstrates the critical role of the bilateral fornix in verbal memory and underscores the importance of a careful risk/benefit analysis when considering neurosurgical intervention to MGNTs and other intracranial lesions adjacent to this structure during neurosurgical planning.
