When should we stop mammography screening for breast cancer in elderly women?

There is insufficient evidence to recommend for or against routine screening mammography beyond the age of 69 years. The best candidates to stop screening are elderly women who have significant comorbidities, poor functional status, low bone mineral density (BMD), little interest in preventive care, or an unwillingness to accept the potential harm of screening. (Grade of Recommendation: C, based on retrospective cohort studies.

Utilizing Surface Area to Volume ratios and Thermal Tolerance of Various Bee Species to Predict their Performance under Rising Global Temperatures

The purpose of this research project is to investigate how rising temperatures, for instance climate change, can affect bees of various body sizes given their essential role in the global food supply through pollination of agricultural crops. To achieve this I utilized 3D imaging and 3D modeling techniques to calculate surface area-to-volume (SA/V) ratios of the bees that otherwise cannot be obtained using conventional methods. SA/V ratios were calculated for 4 different families (Halictidae, Colletidae, Apidae, and Megachilidae) in the order Hymenoptera and were analyzed alongside the bee’s Critical Thermal Maximum (CT Max) data, the maximum heat a bee can withstand before losing mobility, to gain insight on the bee's ability to survive in extreme hot temperatures. It is evident from the data that larger bees, characterized by smaller SA/V ratios, presented a higher CT Max suggesting their greater chance of survival in higher temperatures than smaller bees due to less heat exchange relative to their body size. This data implies that with earth’s rising global temperatures larger bees will likely perform better than smaller bees.This poster was presented at the UCSB Center for Science and Engineering Partnerships (CSEP) summer colloquium in 2023

Contrasting Effects of Errorless Naming Treatment and Gestural Facilitation for Word Retrieval in Aphasia

Purpose- We compared the effects of two treatments for aphasic word retrieval impairments, errorless naming treatment (ENT) and gestural facilitation of naming (GES), within the same individuals, anticipating that the use of gesture would enhance the effect of treatment over errorless treatment alone. In addition to picture naming, we evaluated results for other outcome measures that were largely untested in earlier ENT studies. Methods- In a single participant crossover treatment design, we examined the effects of ENT and GES in eight individuals with stroke-induced aphasia and word retrieval impairments (three semantic anomia, five phonological anomia) in counterbalanced phases across participants. We evaluated effects of the two treatments for a daily picture naming/gesture production probe measure and in standardised aphasia tests and communication rating scales administered across phases of the experiment. Results- Both treatments led to improvements in naming of trained words (small-to-large effect sizes) in individuals with semantic and phonological anomia. Small generalised naming improvements were noted for three individuals with phonological anomia. GES improved use of corresponding gestures for trained words (large effect sizes). Results were largely maintained at one month post-treatment completion. Increases in scores on standardised aphasia testing also occurred for both ENT and GES training. Discussion- Both ENT and GES led to improvements in naming measures, with no clear difference between treatments. Increased use of gestures following GES provided a potential compensatory means of communication for those who did not improve verbal skills. Both treatments are considered to be effective methods to promote recovery of word retrieval and verbal production skills in individuals with aphasia

Appealing Features of Vocational Supports for Latino & non-Latino Transition Age Youth & Young Adult Consumers [English and Spanish versions]

A Spanish translation of this publication is available to download under Additional Files. Describes the Appealing Features of the Vocational Supports for Latino and Non-Latino Transition Aged Youth and Youth Adults (TAYYA) Consumers Study, which focuses on addressing employment disparities of young adults with a serious mental health condition (SMHC) by examining their lived experiences with established vocational support programs. The study pays particular attention to Latino TAYYA as they are a group at high risk for negative outcomes including high unemployment and low educational attainment compared to their white counterparts. They are also less likely to seek specialty mental health services and are the fastest growing racial ethnic group in the United States. Originally published as: Research in the Works, Issue 3, 2011.

How well do doctors know their patients? Evidence from a mandatory access prescription drug monitoring program

Many opioid control policies target the prescribing behavior of health care providers. In this paper, we study the first comprehensive state‐level policy requiring providers to access patients’ opioid history before making prescribing decisions. We compare prescribers in Kentucky, which implemented this policy in 2012, to those in a control state, Indiana. Our main difference‐in‐differences analysis uses the universe of prescriptions filled in the two states to assess how the information provided affected prescribing behavior. We find that a significant share of low‐volume providers stopped prescribing opioids altogether after the policy was implemented, though this change accounted for a small share of the reduction in total volume. The most important margin of response was to prescribe opioids to fewer patients. Although providers disproportionately discontinued treating patients whose opioid histories showed the use of multiple providers, there were also economically meaningful reductions for patients without multiple providers and single‐use acute patients.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/156491/3/hec4020_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/156491/2/hec4020.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/156491/1/hec4020-sup-0001-Supplementaary_data.pd

Embodied Discourses of Literacy in the Lives of Two Preservice Teachers

This study examines the emerging teacher literacy identities of Ian and A.J., two preservice teachers in a graduate teacher education program in the United States. Using a poststructural feminisms theoretical framework, the study illustrates the embodiment of literacy pedagogy discourses in relation to the literacy courses’ discourse of comprehensive literacy and the literacy biographical discourses of Ian and A.J. The results of this study indicate the need to deconstruct how the discourse of comprehensive literacy limits how we, as literacy teacher educators, position, hear and respond to our preservice teachers and suggests the need for differentiation in our teacher education literacy courses
