A new meteor shower from comet 46P/Wirtanen expected in December 2023

Context. Comet 46P/Wirtanen is a near-Earth object (NEO) for which no associated meteor shower has ever been reported. Aims. This study is aimed at improving our understanding of why there has been no observed shower activity for this NEO to date, as well as to consider whether any past activity could be uncovered from the post-prediction results. Methods. The usual dynamic tools for meteoroid streams were used to describe the behavior of the particles ejected by the comet. The resulting modeled meteoroid stream was thoroughly inspected for collisions between the stream and the Earth. Results. The results show a possible encounter forecast for December 12, 2023, between 8:00 and 12:30 UT. The slow entry velocity is typically known to cause dim meteors. The activity level of the shower is highly uncertain due to the absence of reported past showers. Conclusions. Overall, the most optimal observations on the forecasted day would be achieved from Eastern Australia, New Zealand, and Oceania. These observations will help constrain the size distribution of meteoroids from comet 46P/Wirtanen in the millimeter range.Comment: 5 pages, 5 figure

First-Year Medical Student Feedback Regarding the Addition of Online Learning Modules to the Curriculum

Introduction: The first year of the medical student curriculum at the John A. Burns School of Medicine consists of four blocks. The first block–MD1: Health and Illness–is a 9-week introduction to Problem-Based Learning (PBL) and foundational sciences. In response to the COVID-19 pandemic, MD1 introduced online modules (pre-recorded lectures assigned outside of scheduled lecture times) for fall 2020. While student ratings of MD1 were mostly favorable, students expressed specific concerns regarding online modules in MD1 mid-course evaluations. Comments included, “we feel overwhelmed by the length and content in addition to the scheduled lectures we already have” and “we were not huge fans of the online modules”. Additionally, “Q&A and review sessions” corresponding with each online module were scheduled in the second half of MD1 to provide dedicated time for students to meet with instructors. The formats of these sessions were left to the discretion of the instructor, resulting in high variability. Students were surveyed to elaborate their thoughts towards online modules and review sessions. Although this project was done in the context of MD1 online modules, we hope to extend the recommendations to all lectures in the pre-clerkship units. Objectives: The purpose of this study was to identify strengths, areas of improvement, and suggestions regarding online modules assigned in MD1. Methods: A quality improvement online survey was administered in October 2020 to 77 students in the JABSOM Class of 2024. Quantitative and qualitative questions were newly developed based on feedback from the MD1 mid-course evaluations and addressed areas including preferred presentation style, lecture reviews, effective characteristics, and overall sentiment of the online modules. Patterns among the qualitative responses were identified by the authors to recognize student preferences. Results: The survey was completed by 63 (81.8%) students. Of note, 100% of enrolled students earned passing scores on MD1 end-course exams. Students rated their overall feelings about the online modules 5.9±1.5 out of 10. The majority (55.6%) of students preferred practice questions provided and discussed in pre-recorded lectures. Student comments suggested the most effective review session formats were based on instructors’ practice questions or overviews of key lecture slides. Respondents also reported the most effective lectures had exam-like practice questions with explanations and direct connections to MD1 PBL cases. Additionally, respondents recommended scheduling in specific time blocks to watch pre-recorded lectures during school day hours, to more closely mimic live, in-person lectures. Discussion: The prevalence of online learning in medical school curricula has increased, perhaps due to the COVID-19 pandemic. We surveyed the JABSOM Class of 2024 about their MD1 online learning experience and consolidated feedback to the following recommendations. (1) Regarding content, we recommend lecturers (a) relate the material to PBL cases and (b) discuss clinical examples. (2) Regarding practice questions, we recommend lecturers prepare and discuss practice questions during their lectures. (3) Regarding review sessions, we recommend lecturers prepare a summary of both (a) testable, key concepts and (b) additional practice questions. We propose these changes and practices can lead to improved learner satisfaction while maintaining the high standard of learner performance outcomes that faculty and students share.

RHABDOCHONA (RHABDOCHONA) ACUMINATA (NEMATODA) IN FISHES (CHARACIFORMES, ACESTRORHYNCHIDAE) FROM THE TRÊS MARIAS RESERVOIR, UPPER SÃO FRANCISCO RIVER, BRAZIL

Rhabdochona (Rhabdochona) acuminata (Molin, 1860) (Rhabdochonidae) parasitizes the intestine of several species of fish and it has a broad geographical distribution. The present study is the first to report adult specimens of this helminth in Acestrorhynchus britskii Menezes, 1969 and Acestrorhynchus lacustris Lütken, 1875 (Acestrorhynchidae), collected in the Três Marias reservoir, upper São Francisco River, State of Minas Gerais, Brazil. At the same locality, Rhabdochona sp. larvae were found in sympatric populations of forage fishes, Tetragonopterus chalceus Spix & Agassiz, 1829 and Triportheus guentheri (Garman, 1890) which are potential prey to the piscivorous Acestrorhynchids and they are mentioned as possible intermediate or paratenic hosts of this parasite species. The parasite indices of R. acuminata were not influenced by either sex or total length of these piscivorous hosts.Rhabdochona (Rhabdochona) acuminata (Molin, 1860) (Rhabdochonidae) parasita o intestino de várias espécies de peixes e apresenta uma ampla distribuição geográfica. O presente estudo registra pela primeira vez a ocorrência de espécimes adultos deste helminto em Acestrorhynchus britskii Menezes, 1969 e Acestrorhynchus lacustris Lütken, 1875 (Acestrorhynchidae), coletados no Reservatório de Três Marias, Alto Rio São Francisco, Estado de Minas Gerais, Brasil. Nesta mesma localidade, larvas de Rhabdochona sp. foram encontradas em peixes forrageiros simpátricos, Tetragonopterus chalceus Spix & Agassiz, 1829 e Triportheus guentheri (Garman, 1890) potenciais presas dos acestrorhynchídeos piscívoros e relacionadas como possíveis hospedeiros intermediários ou paratênicos dessa espécie de parasito. Os índices parasitários de R. acuminata não foram influenciados pelo sexo e nem pelo comprimento total desses hospedeiros piscívoros

O teleatendimento de terapia ocupacional: um relato de experiência com paciente com comprometimento Pós-COVID-19

A mutação (SARS-CoV-2) produz uma doença infecciosa denominada COVID-19, caracterizada como uma doença respiratória, dessa maneira, ao longo do tempo foram surgindo inúmeros casos de sequelas a médio e a longo prazo por pacientes que tiveram COVID-19, sendo em sua maioria, comprometimentos relacionados ao cognitivo, mais especificamente relacionados à memória de curto prazo e déficits na atenção, afetando a capacidade de uma pessoa de realizar atividades de vida diária. Sendo assim, foi realizado um estudo de caso com uma paciente de uma universidade do Estado de São Paulo, que apresentou queixas de déficits cognitivos que comprometem no gerenciamento de suas atividades relacionadas ao seu trabalho e estudo, desta forma, foram realizadas algumas avaliações e, traçado um plano terapêutico com a realização de 10 atendimentos on-line com duração de 50 minutos semanais, estimulando a memória semântica, a memória de curto prazo, raciocínio, atenção sustentada e criação de um template para elaboração e organização da rotina diária. Obtendo como resultado aquisição de novos hábitos, como pratica de yoga, de hidroginástica, momentos de auto-cuidado, diminuição de comportamentos ansiosos e de frustração quando comparado à situação anterior, retorno à sua rotina diária anterior, demonstrando o impacto da intervenção da Terapia Ocupacional na reabilitação de pacientes pós COVID-19
