Abstract
PURPOSE Conversation treatment for people with aphasia (PwA) can lead to significant changes in language impairment and quality of life. The COVID-19 pandemic has resulted in the greater use of telepractice treatment delivery. However, there is little evidence regarding the efficacy of telepractice conversation groups. This study investigated the effects of telepractice group conversation treatment on standardized measures of language function and socially oriented/patient-reported outcomes compared to in-person and no-treatment control data. METHOD This study used a mixed within- and between-groups design (repeated measure/pre-post treatment), with a single-subject delayed treatment design (Shadish & Rindskopf, 2007) to establish baseline, pretreatment, and posttreatment periods for the telepractice group. Telepractice results pre- and posttreatment were compared with historical in-person and no-treatment control data obtained from a larger randomized control trial (RCT) from DeDe et al. (2019). The historical comparison data were a subset of RCT participants from the same location and included six in-person participants and seven no-treatment control group participants. RESULTS Results of standardized testing conducted at baseline, pretreatment, and posttreatment intervals revealed significant improvement from pre- to posttreatment on repetition and picture description tasks for the telepractice group, and significant improvement from pre- to posttreatment on the Aphasia Communication Outcome Measure, total number of relevant utterances, and percentage of complete utterances for the in-person conversation group. No significant differences were observed in the no-treatment groups. CONCLUSIONS In contrast to the no-treatment condition, both the in-person and telepractice conditions showed the benefits of conversation group treatment. The in-person treatment condition showed improvements in a wider number of outcome measures than the telepractice condition. Overall, the results prompt further research regarding telepractice group conversation treatment for PwA.

Abstract
BACKGROUND Aphasia book clubs were developed to support connecting with literature and reading for pleasure within an aphasia-friendly environment. Bibliotherapy is an evidence-based therapeutic approach, in which a book is selected to address the challenges facing the reader. Its aim is to facilitate a deeper understanding of a lived experience in order to promote healing, strategy development, and adjustment. Aphasia book clubs provide an opportunity to discuss books about the challenges associated with aphasia. A recent book, Identity theft: Rediscovering ourselves after stroke recounts the stroke recovery story of Dr. Debra Meyerson and 22 other stroke survivors. Identity Theft focuses on the need to reconstruct positive identities despite remaining disabilities to facilitate rebuilding rewarding lives. The purpose of this study is to understand the impact of reading Identity Theft in an aphasia book club for people with aphasia (PwA). METHOD 27 PwA read the book Identity Theft in one of four online aphasia book clubs offered by two universities. Weekly discussions were facilitated by graduate SLP students under the supervision of experienced clinicians. At the end of the 10 week program, semi-structured qualitative interviews were conducted with participants to understand the lived experience. Interviews were analyzed using reflexive thematic analysis. RESULTS Analysis of the interview data generated four main themes and 13 subthemes. The main themes included: Mechanism for Reflection, Power of Community, Engaged Learning, and Therapeutic Environment. Interview extracts illustrate the way these themes support increasing self-efficacy and rebuilding a positive identity. CONCLUSION The themes align positively with outcomes associated with the bibliotherapy process. Themes also integrate into a self-management model that promotes self-efficacy through education, support, awareness, problem solving and goal setting. Caveats included determining participant readiness to examine recovery issues and facilitator preparation. Aphasia book clubs surrounding psychosocial texts may help PwA reconstruct a positive post-stroke identity.

Abstract
PURPOSE Evidence has shown that group conversation treatment may improve communication and reduce social isolation for people with aphasia. However, little is known about the impact of conversation group treatment on measures of discourse. This project explored the impact of conversation treatment on measures of monologic discourse. METHOD In this randomized controlled trial, 48 participants with chronic aphasia were randomly assigned to dyadic, large group, or control conditions. Conversation group treatment was provided for 1 hr, twice per week, for 10 weeks. Discourse samples were collected and coded at pretreatment, posttreatment, and 6-week maintenance. There were three narrative tasks: (a) Comprehensive Aphasia Test (CAT) picture description, (b) Cat Rescue Picture, and (c) Cinderella retell. All narratives were coded using the percent correct information units (percent CIUs), the CAT standardized narrative analysis method, and the complete utterance (CU) method. RESULTS No significant changes were observed on percent CIU, which was the primary outcome measure. The treated groups demonstrated improvement on aspects of the CU method following treatment, whereas the control group did not. Significant changes were observed for other CIU measures and the CAT standardized narrative analysis in both the treated and control groups. CONCLUSIONS The results suggest that the CU measures were more sensitive to the effects of conversation treatment in monologic discourse compared to CIU and CAT measures. Changes were more common in absolute rather than relative values, suggesting that conversation treatment impacts the overall amount of language produced rather than efficiency of production.

Abstract
Coronavirus disease-19 (COVID-19) vaccine response data for patients with hematologic malignancy, who carry high risk for severe COVID-19 illness, are incomplete. In a study of 551 hematologic malignancy patients with leukemia, lymphoma, and multiple myeloma, anti-SARS-CoV-2 spike IgG titers and neutralizing activity were measured at 1 and 3 months from initial vaccination. Compared with healthy controls, patients with hematologic malignancy had attenuated antibody titers at 1 and 3 months. Furthermore, patients with hematologic malignancy had markedly diminished neutralizing capacity of 26.3% at 1 month and 43.6% at 3 months, despite positive seroconversion rates of 51.5% and 68.9% at the respective time points. Healthy controls had 93.2% and 100% neutralizing capacity at 1 and 3 months, respectively. Patients with leukemia, lymphoma, and multiple myeloma on observation had uniformly blunted responses. Treatment with Bruton tyrosine kinase inhibitors, venetoclax, phosphoinositide 3-kinase inhibitors, anti-CD19/CD20-directed therapies, and anti-CD38/B-cell maturation antigen-directed therapies substantially hindered responses, but single-agent immunomodulatory agents did not. Significance Patients with hematologic malignancy have compromised COVID-19 vaccine responses at baseline that are further suppressed by active therapy, with many patients having insufficient neutralizing capacity despite positive antibody titers. Refining vaccine response parameters is critical to guiding clinical care, including the indication for booster vaccines, for this vulnerable population.See related article by Tamari et al., p. 577.

Abstract
Abstract
BACKGROUND: Pharmacological targeting of driver alterations in cancer has resulted in many clinical successes but is limited by concurrent or novel genomic alterations. One potential explanation for this heterogeneity is the presence of additional genomic alterations which modify the degree of dependence on the targeted driver mutation. Metastatic prostate cancer (mPCa) serves as a relevant example, where the molecular target is the androgen receptor (AR) which functions as a lineage survival factor of luminal prostate epithelial cells. Next generation AR targeted therapies such as abiraterone, enzalutamide and apalutamide have significantly improved the survival of men with mPCa and achieved exciting clinical success. However, resistance to these therapies with disease progression is unfortunately inevitable, with intrinsic resistance noted in around 30% patients and acquired resistance in most patients. Therefore, there is an unmet need to understand the mechanism of therapy resistance to AR targeted therapies and identify novel therapeutic approach to prevent or reverse resistance. Previously, we have revealed that the deactivation of two genes, TP53 and RB1, confers AR targeted therapy resistance through a novel mechanism by which tumor cells acquire lineage plasticity and transit to a multi-lineage, progenitor-like state no longer dependent on AR. This lineage plasticity and resistance is enabled by the activation of SOX2 and is completely reversible by knocking down SOX2. This observation not only adds clarity to the mechanism of resistance, but also suggests that appropriate clinical interventions of lineage plasticity may be a potential avenue to overcome resistance. However, there is only 10% mPCa patients carrying homozygous deletions in both TP53 and RB1 loci, thus additional genomic alterations may be responsible for the resistance in other patients.
METHODS: To gain functional insight into the genes impacted by the copy number alterations in mPCa, we screened 4234 short hairpin RNAs (shRNAs) targeting 730 genes often deleted in human prostate cancer (annotated from a survey of six prostate cancer genomic datasets) for hairpins that confer in vivo resistance to the antiandrogen enzalutamide, in a well credentialed enzalutamide-sensitive xenograft model LNCaP/AR. More than 350 resistant tumors emerged by 16 weeks of xenografting and the genomic DNA of these tumors were extracted and sequenced to determine the enrichment of specific shRNAs compared to the starting material. A classic probabilistic model RIGER-E was used to determine the significance of enrichment of each hairpins/genes.
RESULTS: The chromodomain helicase DNA-binding protein 1 (CHD1) emerged as a top candidate, a finding supported by patient data showing that CHD1 expression is inversely correlated with clinical benefit from AR targeted therapy enzalutamide. CRISPR based depletion of CHD1 confers significant resistance to enzalutamide both in vitro and in vivo, supported by similar results from multiple human prostate cancer cell line models. To our surprise, we observed sustained inhibition of the canonical AR target genes, indicating that CHD1 loss might activate transcriptional programs that relieve prostate tumor cells from their dependence on AR by reprogramming away from their luminal lineage, as we have observed in the setting of combined loss of RB1 and TP53. Indeed, CHD1 loss led to global changes in open and closed chromatin, indicative of an altered chromatin state, with associated changes in gene expression. Integrative analysis of ATAC-seq and RNA-seq changes identified 22 transcription factors as candidate drivers of enzalutamide resistance. CRISPR deletion of four of these (NR3C1, BRN2, NR2F1, TBX2) restored in vitro enzalutamide sensitivity in CHD1 deleted cells. Independently derived, enzalutamide-resistant, CHD1-deleted subclones expressed elevated levels of 1 or more of these 4 transcription factors. This pattern suggests a state of chromatin plasticity and enhanced heterogeneity, initiated by CHD1 loss, which enables upregulation of distinct sets of genes in response to selective pressure. This concept is further supported by RNA-seq data from a mCRPC patients cohort, in which we examined the co-association of CHD1 levels with each of these four TFs across 212 tumors. Unsupervised clustering analysis of just these five genes identified five distinct clusters, four of which display relatively higher expression of either CHD1 or one or two of these four resistance TFs. Interestingly, we observed altered expression of many canonical lineage specific genes in the same panel of CHD1-deleted, enzalutamide resistant xenografts that displayed heterogenous upregulation of the four TFs, including consistent downregulation of luminal genes and upregulation of genes specify epithelial to mesenchymal transition (EMT). Furthermore, these upregulation of 4 resistance TFs, as well as the observed lineage switchs, are both rapid and reversible, suggesting a status of plasticity. Collectively, these results indicate that CHD1 loss establishes an altered chromatin landscape which, in the face of stresses such as antiandrogen therapy, enables resistant subclones to emerge through activation of alternative, non-luminal lineage programs that reduce dependence on AR.
CONCLUSIONS: We demonstrated that loss of the chromodomain gene CHD1, a commonly deleted prostate cancer gene (in 15~20% patients), through global effects on chromatin, establishes a state of plasticity that accelerates the development of AR targeted therapy resistance through heterogeneous activation of downstream effectors, which mediated the transition away from luminal lineage identity and AR dependency. This model provides the first demonstration that early genomic lesions of critical epigenetic modulator promotes prostate cancer heterogeneity and lineage plasticity, consequently leading to the resistance to AR targeted therapy. Therefore, appropriate clinical intervention of these heterogenous resistance driver TFs, as well as the chromatin dysregulation, may be potential therapeutic avenues to prevent or reverse AR targeted resistance.

Metastatic prostate cancer is characterized by recurrent genomic copy number alterations that are presumed to contribute to resistance to hormone therapy. We identified CHD1 loss as a cause of antiandrogen resistance in an in vivo small hairpin RNA (shRNA) screen of 730 genes deleted in prostate cancer. ATAC-seq and RNA-seq analyses showed that CHD1 loss resulted in global changes in open and closed chromatin with associated transcriptomic changes. Integrative analysis of this data, together with CRISPR-based functional screening, identified four transcription factors (NR3C1, POU3F2, NR2F1, and TBX2) that contribute to antiandrogen resistance, with associated activation of non-luminal lineage programs. Thus, CHD1 loss results in chromatin dysregulation, thereby establishing a state of transcriptional plasticity that enables the emergence of antiandrogen resistance through heterogeneous mechanisms.

Abstract
An estimated 390,000 to 520,000 individuals with severe aphasia (IWSA) currently live in the United States. IWSA experience profound social isolation, which is associated with a wide range of negative health outcomes, including mortality. Treatments for severe aphasia frequently focus on compensatory communication approaches or a discrete communication act rather than on participation-based treatment. The purpose of this study was to determine whether IWSA demonstrated improved performance on standardized language measures, patient-reported outcome measures, and connected speech samples as a result of client-centered conversation group treatment. Results of assessments conducted at pretreatment, posttreatment, and maintenance intervals were variable across participants. All participants demonstrated improvement in at least one of the outcome measures considered. Importantly, none of these measures fully captured how IWSA were able to convey their thoughts in supported conversation. The results lend support for the use of conversation treatment for, and for further study in, this subpopulation of individuals with aphasia.

Abstract
Purpose Group conversation treatment has the potential to improve communication and reduce social isolation for people with aphasia. This project examined how 2 conflicting hypotheses-treatment dosage and group dynamics-affect treatment outcomes. Method Forty-eight participants with chronic aphasia were randomly assigned to either a dyad, a large group, or a delayed control group. Conversation group treatment was provided for an hour, twice per week, for 10 weeks. Individual goals were developed by each participant and addressed in the context of thematically oriented conversation treatment. Standardized testing across language domains was completed pretreatment (Time 1), posttreatment (Time 2), at a 6-week maintenance point (Time 3), and at 11-month follow-up for the experimental groups. Results Treatment groups showed greater changes on standardized measures than the control group posttreatment. Dyads showed the most changes on measures of language impairment, whereas changes on the self-reported functional communication measure (Aphasia Communication Outcome Measure) and connected speech task only showed significant changes in the large group. Conclusions This randomized controlled trial on conversation treatment indicated that both treatment groups-but not the delayed control group-showed significant changes on standardized tests. Hence, conversation treatment is associated with changes in measures of language impairment and quality of life. Dyads showed the most changes on measures of language impairment, whereas changes on the functional communication measure (Aphasia Communication Outcome Measure) and discourse production only showed significant changes in the large group. Thus, group size may be associated with effects on different types of outcome measures.

Abstract
BACKGROUND Traditional ecological knowledge (TEK) is a conceptual framework that highlights Indigenous knowledge (IK) systems. Although scientific literature has noted the relevance of TEK for environmental research since the 1980s, little attention has been given to how Native American (NA) scholars engage with it to shape tribal-based research on health, nor how non-Native scholars can coordinate their approaches with TEK. This coordination is of particular importance for environmental health sciences (EHS) research exploring interdisciplinary approaches and the integration of environmental and human health. OBJECTIVE Our perspective on TEK arose from a series of Health and Culture Research Group (HCRG) workshops that identified gaps in existing EHS methodologies that are based on a reliance on Euro-American concepts for assessing environmental exposures in tribal communities. These prior methods neither take into account cultural behavior nor community responses to these. Our objective is to consider NA perspectives on TEK when analyzing relationships between health and the environment and to look at how these may be applied to address this gap. DISCUSSION The authors—the majority of whom are NA scholars—highlight two research areas that consider health from a TEK perspective: food systems and knowledge of medicinal plants. This research has yielded data, methods, and knowledge that have helped Indigenous communities better define and reduce health risks and protect local natural food resources, and this TEK approach may prove of value to EHS research. CONCLUSION NA perspectives on TEK resulting from the HCRG workshops provide an opportunity for developing more accurate Indigenous health indicators (IHI) reflecting the conceptualizations of health maintained in these communities. This approach has the potential to bridge the scientific study of exposure with methods addressing a tribal perspective on the sociocultural determinants of health, identifying potential new areas of inquiry in EHS that afford nuanced evaluations of exposures and outcomes in tribal communities. https://doi.org/10.1289/EHP1944.

Abstract
Some cancers evade targeted therapies through a mechanism known as lineage plasticity, whereby tumor cells acquire phenotypic characteristics of a cell lineage whose survival no longer depends on the drug target. We use in vitro and in vivo human prostate cancer models to show that these tumors can develop resistance to the antiandrogen drug enzalutamide by a phenotypic shift from androgen receptor (AR)-dependent luminal epithelial cells to AR-independent basal-like cells. This lineage plasticity is enabled by the loss of TP53 and RB1 function, is mediated by increased expression of the reprogramming transcription factor SOX2, and can be reversed by restoring TP53 and RB1 function or by inhibiting SOX2 expression. Thus, mutations in tumor suppressor genes can create a state of increased cellular plasticity that, when challenged with antiandrogen therapy, promotes resistance through lineage switching.

Abstract
We conducted a phase II trial investigating the impact of fractionated hematopoietic cell infusions on engraftment kinetics and symptom burden in patients with plasma cell myeloma (PCM) undergoing autologous hematopoietic cell transplant (AHCT). We hypothesized that multiple hematopoietic cell infusions would reduce duration of neutropenia and enhance immune recovery resulting in a better tolerated procedure. Twenty-six patients received high-dose melphalan followed by multiple cell infusions (Days 0, +2, +4, +6) and were compared to PCM patients (N = 77) who received high-dose melphalan and a single infusion (Day 0) (concurrent control group). The primary endpoint was number of days with ANC <500K/mcL. Symptom burden was assessed using the MSK-modified MD Anderson Symptom Inventory. Median duration of neutropenia was similar in study (4 days, range 3-5) and control patients (4 days, range 3-9) (p = 0.654). There was no significant difference in the number of red cell or platelet transfusions, days of fever, diarrhea, antibiotics, number of documented infections, or length of admission. Symptom burden surveys showed that AHCT was well-tolerated in both study and control patients. We conclude that fractionated stem cell infusions following high-dose melphalan do not enhance engraftment kinetics or significantly alter patients' clinical course following AHCT in PCM.

Abstract
BACKGROUND Social science research has been central in documenting and analyzing community discovery of environmental exposure and consequential processes. Collaboration with environmental health science through team projects has advanced and improved our understanding of environmental health and justice. OBJECTIVE We sought to identify diverse methods and topics in which social scientists have expanded environmental health understandings at multiple levels, to examine how transdisciplinary environmental health research fosters better science, and to learn how these partnerships have been able to flourish because of the support from National Institute of Environmental Health Sciences (NIEHS). METHODS We analyzed various types of social science research to investigate how social science contributes to environmental health. We also examined NIEHS programs that foster social science. In addition, we developed a case study of a community-based participation research project in Akwesasne in order to demonstrate how social science has enhanced environmental health science. RESULTS Social science has informed environmental health science through ethnographic studies of contaminated communities, analysis of spatial distribution of environmental injustice, psychological experience of contamination, social construction of risk and risk perception, and social impacts of disasters. Social science-environmental health team science has altered the way scientists traditionally explore exposure by pressing for cumulative exposure approaches and providing research data for policy applications. CONCLUSIONS A transdisciplinary approach for environmental health practice has emerged that engages the social sciences to paint a full picture of the consequences of contamination so that policy makers, regulators, public health officials, and other stakeholders can better ameliorate impacts and prevent future exposure.

Abstract
Abstract
Castration-resistant prostate cancer (CRPC) is one of the most difficult cancers to treat with conventional methods and is responsible for nearly all prostate cancer deaths in the US. The Sawyers laboratory first showed that the primary mechanism of resistance to antiandrogen therapy is elevated androgen receptor (AR) expression. Research based on this finding has led to the development of next-generation antiandrogen: enzalutamide. Despite the exciting clinical success of enzalutamide, about 60% of patients exhibit various degrees of resistance to this agent. Highly variable responses to enzalutamide limit the clinical benefit of this novel antiandrogen, underscoring the importance of understanding the mechanisms of enzalutamide resistance. Most recently, an unbiased SU2C-Prostate Cancer Dream Team metastatic CRPC sequencing project led by Dr. Sawyers and Dr. Chinnaiyan revealed that mutations in the TP53 locus are the most significantly enriched alteration in CRPC tumors when compared to primary prostate cancers. Moreover, deletions and decreased expressions of the TP53 and RB1 loci (co-occurrence and individual occurrence) are more commonly associated with CRPC than with primary tumors. These results established that alteration of the TP53 and RB1 pathways are associated with the development of antiandrogen resistance.
By knockdowning TP53 or/and RB1 in the castration resistant LNCaP/AR model, we demonstrate that the disruption of either TP53 or RB1 alone confers significant resistance to enzalutamide both in vitro and in vivo. Strikingly, the co-inactivation of these pathways confers the most dramatic resistance. Since up-regulation of either AR or AR target genes is not observed in the resistant tumors, loss of TP53 and RB1 function confers enzalutamide resistance likely through an AR independent mechanism. In the clinic, resistance to enzalutamide is increasingly being associated with a transition to a poorly differentiated or neuroendocrine-like histology. Interestingly, we observed significant up-regulations of the basal cell marker Ck5 and the neuroendocrine-like cell marker Synaptophysin in the TP53 and RB1 inactivated cells, as well as down-regulation of the luminal cell marker Ck8. The differences between these markers became even greater after enzalutamide treatment. By using the p53-stabilizing drug Nutlin, level of p53 is rescued and consequently the the decrease of AR protein caused by RB1 and TP53 knockdown is reversed. These results strongly suggest that interference of TP53 and RB1 pathways confers antiandrogen resistance by “priming” prostate cancer cells to reprogramming or transdifferentiation, likely neuroendocrine-like differentiation, in response to treatment. Futher experiments will be performed to assess the molecular mechanism of TP53/RB1 alterations in mediating cell programming and conferring antiandrogen resistance.

Abstract
We demonstrate, for the first time, OCT imaging capabilities of a novel, akinetic (without any form of movement in the tuning mechanism), all-semiconductor, all-electronic tunable, compact and flexible swept source laser technology at 1550 nm and 1310 nm. To investigate its OCT performance, 2D and 3D ex vivo and in vivo OCT imaging was performed at different sweep rates, from 20 kHz up to 200 kHz, with different axial resolutions, about 10 µm to 20 µm, and at different coherence gate displacements, from zero delay to >17 cm. Laser source phase linearity and phase repeatability standard deviation of <2 mrad (<160 pm) were observed without external phase referencing, indicating that the laser operated close to the shot noise limit (~2 × factor); constant percentile wavelengths variations of sliding RIN and ortho RIN <0.2% could be demonstrated, ~5 times better as compared to other swept laser technologies.

Abstract
INTRODUCTION Fish advisories are issued in an effort to protect human health from exposure to contaminants, but Native American communities may suffer unintended health, social, and cultural consequences as a result of warnings against eating local fish. This paper focuses on the Mohawk community of Akwesasne, which lies downstream from a Superfund site, and explores how fish advisories have impacted fish consumption and health. METHODS 65 Akwesasne community members were interviewed between March 2008 and April 2009. Interviews were semi-structured, lasted from 30-90 minutes and consisted of open-ended questions about the impacts of environmental contamination on the community. Detailed field notes were also maintained during extensive visits between 2007-2011. Interviews were transcribed, and these transcripts as well as the field notes were analyzed in NVivo 8.0. This research received approval from the Akwesasne Task Force on the Environment Research Advisory Committee, as well as the Brown University Institutional Review Board. RESULTS Three-quarters of the 50 Akwesasne Mohawks interviewed have ceased or significantly curtailed their local fish consumption due to the issuance of fish advisories or witnessing or hearing about deformities on fish. Many of these respondents have turned to outside sources of fish, from other communities or from grocery stores. This change in fish consumption concerns many residents because cultural and social connections developed around fishing are being lost and because fish has been replaced with high-fat high-carb processed foods, which has led to other health complications. One-quarter of the 50 interviewees still eat local fish, but these are generally middle-aged or older residents; fish consumption no longer occurs in the multi-generational social context it once did. CONCLUSIONS Human health in Native American communities such as Akwesasne is intimately tied to the health of the environment. Fish advisories should not be used as an institutional control to protect humans from exposure to contaminants; if Akwesasne are to achieve optimal health, the contaminated environment has to be remediated to a level that supports clean, edible fish.

Abstract
BACKGROUND Indigenous American communities face disproportionate health burdens and environmental health risks compared with the average North American population. These health impacts are issues of both environmental and reproductive justice. OBJECTIVES In this commentary, we review five indigenous communities in various stages of environmental health research and discuss the intersection of environmental health and reproductive justice issues in these communities as well as the limitations of legal recourse. DISCUSSION The health disparities impacting life expectancy and reproductive capabilities in indigenous communities are due to a combination of social, economic, and environmental factors. The system of federal environmental and Indian law is insufficient to protect indigenous communities from environmental contamination. Many communities are interested in developing appropriate research partnerships in order to discern the full impact of environmental contamination and prevent further damage. CONCLUSIONS Continued research involving collaborative partnerships among scientific researchers, community members, and health care providers is needed to determine the impacts of this contamination and to develop approaches for remediation and policy interventions.

Abstract
PURPOSE Prior studies of discourse comprehension have concluded that the deficits of persons with aphasia (PWA) in syntactically based comprehension of sentences in isolation are not predictive of deficits in comprehension of sentences in discourse (Brookshire & Nicholas, 1984; Caplan & Evans, 1990). However, these studies used semantically constrained sentences in discourse, which do not require syntactic analysis to be understood. A discourse task was developed to assess the effect of syntactic complexity, among other factors, on discourse comprehension in PWA. METHOD Thirty-eight PWA and 30 neurologically healthy control participants were presented with passages that contained 2-3 semantically reversible sentences that were either syntactically simple or syntactically complex. The passages were presented auditorily, and comprehension was assessed with the auditory and written presentation of 4 multiple-choice questions immediately following each passage. RESULTS Passages with syntactically simple sentences were better understood than passages with syntactically complex sentences. Moreover, semantically constrained sentences were more likely to be accurately interpreted than semantically reversible sentences. Comprehension accuracy on our test correlated positively with comprehension accuracy on an existing test. CONCLUSION The presence of semantically reversible, syntactically complex sentences in a passage affects comprehension of the passage in both PWA and neurologically healthy individuals.

Abstract
8533 Background: In a high risk population of pts with newly diagnosed or primary refractory MM, we prospectively studied FDG PET imaging to determine the value of PET/CT in assessing therapeutic response. Methods: Forty pts with high-risk MM defined as ISS II, ISS III or presence of extramedullary plasmacytoma have been enrolled on study and treated using a combination of bortezomib, pegylated liposomal doxorubicin hydrochloride (Doxil), and dexamethasone (BDD) for 3 cycles followed by 2 cycles of thalidomide and dexamethasone for patients achieving at least PR. Pts were assessed using serial FDG PET imaging: at baseline (BL), after 3 cycles of BDD and at end of study (EOS). FDG PET response was determined using European Organization for research and treatment of cancer (EORTC) recommendations. MM disease response was assessed according to the International Myeloma Working Group (IMWG) criteria. Results: Median age of pts enrolled was 59 yrs (range 41–80), 62% male, 38% ISS II, 47% ISS III, and 15% ISS I with soft-tissue disease. Thirty-five percent (14/40) had soft-tissue involvement with MM. At completion of protocol therapy, the ORR was 79%, with 44% of pts achieving CR/nCR and 59% ≥ VGPR. Ninety FDG PET scans were performed in 40 pts; 25 pts were evaluable for FDG PET response. The other pts are as follows: 2 had negative FDG PET at BL, 6 were taken off study (5 for toxicity and 1 with CR), 1 FDG PET was unable to be compared due to technical differences and 6 pts have not completed treatment. Seventeen of the 25 pts had PR by FDG PET, 5 had SD and 3 PD; none of the pts had CR. There was little agreement between MM disease response and FDG PET responses (Kappa statistic, 0.05). Three pts with PD by FDG PET, had PR (n=2) or CR (n=1) by IMWG criteria. One had granulomatous disease rather than MM at biopsy. In 1 pt with progression of disease with a progressive skull-based plasmacytoma, FDG PET was scored as PR by EORTC criteria. Conclusions: There was poor agreement between FDG PET response and MM disease response by IMWG criteria. Serial FDG PET did not provide additional information for therapeutic response assessment in pts with newly diagnosed or primary refractory MM. [Table: see text]

Abstract
One way to ensure that social and ethical implications (SEI) of nanotechnology research are taken into consideration early in research projects is to incorporate ethical concepts into university science education. In this paper, we describe an interdisciplinary nanotechnology university science course and the ways in which the opinions of students regarding the ethical implications of nanotechnology research were influenced by the course. From an SEI perspective, there is value in scientists being aware of the need to make explicit the uncertainties that always exist in scientific and technological research and development. By the end of the class, a majority of the students felt that risks and ethical issues are not well understood by scientists working in nanomaterials, and ethical training was recommended for these scientists. Findings from this study speak to the importance of this type of interdisciplinary class in preparing students for collaborative research and making them aware of issues important to the general public who someday will become consumers of products derived from nanotechnology research.

Abstract
The NIEHS funds several basic and applied research programs, many of which also require research translation or outreach. This paper reports on a project by the Brown University Superfund Basic Research Program (SBRP), in which outreach and research translation teams collaborated with state regulatory agency personnel and community activists on a legislative initiative to mitigate the financial impacts of living in a contaminated community. The Environmentally Compromised Home Ownership (ECHO) program makes home equity loans of up to $25,000 available to qualified applicants. This collaboration provides a case study in community engagement and demonstrates how research translation and outreach activities that are clearly differentiated yet well-integrated can improve a suite of basic and applied research. Although engaging diverse constituencies can be difficult community-engaged translation and outreach have the potential to make research findings more useful to communities, address some of the social impacts of contamination, and empower stakeholders to pursue their individual and collectively held goals for remediation. The NIEHS has recently renewed its commitment to community-engaged research and advocacy, making this an optimal time to reflect on how basic research programs that engage stakeholders through research translation and outreach can add value to the overall research enterprise.

Abstract
BACKGROUND Regulatory requirements for resident working hours were designed to improve patient care. Compliance challenges a training program to meet procedural and clinical requirements. This is a retrospective study of a 5-year experience in addressing the challenges and studying the impact of compliance on resident caseload and board performance. METHODS Our surgical program adopted strict start/stop working hours for clinical contact. Program leadership modified the program to establish procedural and performance criteria. Procedures were prioritized and assignments were changed to maximize clinical and procedural experience while reducing redundancy of experience. Procedural activity was monitored frequently. Compliance with working hour regulations was monitored and behavior modified where necessary. A web based computer program was developed to improve measurement of compliance and provide feedback. Outcome measures included both the number of procedures as reported by the ACGME and performance on the American Board of Surgery, Qualifying Examination. RESULTS Working hour compliance is greater than 95%. First time pass rate on the Qualifying examination is 90% (45/50). There is no significant difference in the procedural activity. CONCLUSION Complying with working hour regulations improves the quality of a resident's life and can be achieved while maintaining procedural experience and guaranteeing academic development.

Abstract
To evaluate the utility of the oral examination in a surgical clerkship, we designed a prospective and randomized study to relate the subjective impressions of experienced examiners with an objective measure of cognitive knowledge. The examiners were asked to score the student's performance as honors, high satisfactory, satisfactory, or unsatisfactory, according to their subjective impression of the student's ability. Student performance was grouped according to oral examination performance. The cognitive performance in the honors group was significantly better than that of the other groups (Student's t-test, p = 0.05). There was a significant difference in cognitive performance for oral examination groups throughout the rotations (analysis of variance, p = 0.000; Kruskal Wallis, p = 0.05). The oral examination is useful to identify a high level of cognitive achievement but cannot discriminate between groups of median to low competence. It should be used for educational feedback, career counseling, residency recommendations, and professional development.

Abstract
BACKGROUND This is a prospective study that compares operative experience with performance on the American Board of Surgery Inservice Training Examination (ABSITE) to establish the primacy of procedural experience in the graduate training environment. METHODS Operative experience was determined from a computerized log of surgical procedures. The Report D of the 1991 ABSITE was used to assign each test item to specific operative procedures and to determine the frequency of the correct response (Fcr) for each item. The fraction of operative procedures (Fs) was determined for each category of surgical procedures (Fs = Number of procedures as surgeon/Total number of procedures). The Fcr was compared to the Fs by use of the Pearson correlation coefficient with significance at 95% confidence. RESULTS Forty-two residents reported doing 8357 surgical procedures as surgeon in 12 months. Report D contained 209 test items. Of these, 162 items could be assigned to 26 categories of surgical procedures. The Fcr correlated directly with the Fs (p = 0.002, r = 0.605). CONCLUSIONS A significant correlation exists between the experience of surgical residents as surgeon and their performance on the ABSITE:

Abstract
This is a case report of a 41-year-old woman who required surgical removal of a Greenfield filter 7 months after placement. The filter developed several complications. Two struts were noted to be completely separated from the filter and lodged in the infrarenal vena cava. The filter had migrated to a resting position in the right renal, vein with two struts perforating the renal vein and inferior vena caval junction. The perforating struts were intraperitoneal and were found to impinge on the right ureter with seromuscular involvement of the second portion of the duodenum. No free perforation was noted at the time of exploration.

Abstract
Proliferative pancreatic cysts are subdivided into microcystic and mucinous cystadenomas. These rare, slow-growing, multilocular lesions usually remain localized for long periods of time, therefore frequently becoming rather sizeable before becoming symptomatic. Patients present with intermittent abdominal or back pain, nausea and vomiting, early satiety, and a palpable mass without a history of trauma or alcoholism. Computed tomographic scanning is the most useful laboratory test. The lesions are more often found in women, with the microcystic adenomas usually located in the head of the pancreas and the mucinous lesions in the pancreatic body or tail. At surgery, if it is at all possible, the lesions should be completely removed, even if it means performance of a Whipple procedure. This is particularly important for mucinous cysts because of their potential for malignant degeneration. Internal drainage or marsupialization procedures should not be done in these patients. The long-term results are excellent if the entire lesion is removed.

Abstract
Experimental and clinical evidence show that endogenous opiates (endorphins) contribute to the pathophysiology of circulatory shock. The authors evaluated the effectiveness and safety of continuous infusion of naloxone in five septic patients with prolonged hypotension unresponsive to volume replacement and dopamine infusion. Naloxone (2 mg bolus) was intravenously administered and continued at 0.25 mg/hr for 24 to 48 hours. All five patients had significant increase in mean arterial pressure of between 20 and 30 mmHg (P less than 0.0012). Cardiac index, systemic vascular resistance, and pulmonary arterial pressure were not significantly altered; however, there was a significant difference in pulmonary capillary wedge pressure (P less than 0.034) and urinary output (P less than 0.0273). Subjects did not experience side effects with naloxone. We conclude that continuous infusion of naloxone can reverse endorphin-mediated hypotension in septic shock patients.

Abstract
Internal carotid injuries in zone III near the base of the skull are technically the most challenging of the carotid injuries. Diagnostic angiography is important to evaluate the exact site and extent of injury and the presence or absence of prograde flow in the injured segment. Vascular repair in this area is highly dependent on the adequacy of surgical exposure. Previous approaches have emphasized displacement of the mandible either by subluxation or mandibulotomy. Problems related to mandibulotomy, such as intraoral contamination, infection, and nonunion, are potential complications of this approach to the high carotid artery. In addition, it does not give adequate exposure of the internal carotid artery at the critical area, near the base of the skull. Experience gained from the extended radical neck dissection exposing the internal carotid artery up to the skull base has demonstrated that a posterolateral anatomic approach can provide superior exposure of the high carotid artery with lower morbidity and shortened operative time. This surgical approach involves cutting the sternomastoid muscle close to the mastoid and dissecting all the tissues away from the surface of the mastoid. Dividing the posterior belly of the digastric and styloid group of muscles assists in exposure of the internal carotid artery. Rarely, dissection of the facial nerve and removal of the tail of parotid add additional access to this area. This article describes the stepwise anatomic approach to the internal carotid artery near the base of the skull.

Abstract
The multicentric occurrence of tumors of the upper aerodigestive tract has been well described, with an incidence ranging from 5 to 16 percent. Detection of a synchronous primary tumor at the time of initial work-up is crucial both for management and final outcome. However, there is a diversity of opinions regarding the extent of the work-up to search for a second primary tumor. Some investigators consider routine panendoscopy to be essential for every patient with a head and neck primary tumor. Routine esophagoscopy and bronchoscopy with bronchial washings in the absence of specific symptoms appear to have minimal benefit and high cost. In our study of 140 consecutive patients with primary squamous cell carcinoma of the head and neck seen over a period of 3 years, detailed history, thorough head and neck examination, routine chest radiograph, and barium swallow when indicated were sufficient to identify 18 patients (13 percent) with a second primary tumor in the upper aerodigestive tract. The synchronous tumors of eight patients were in the head and neck area, seven patients had carcinoma of the lung, and three patients had a second primary in the esophagus. Two patients had three synchronous primaries. Follow-up of these patients ranged from 1 to 4 years. Panendoscopy with cytologic washings was performed routinely. We questioned the cost-effectiveness of routine triscopy in every patient with head and neck cancer.
