RESUMO
Medical-school applicants learn from many sources that they must stand out to fit in. Many construct self-presentations intended to appeal to medical-school admissions committees from the raw materials of work and volunteer experiences, in order to demonstrate that they will succeed in a demanding profession to which access is tightly controlled. Borrowing from the field of architecture the lens of construction ecology, which considers buildings in relation to the global effects of the resources required for their construction, we reframe medical-school admissions as a social phenomenon that has far-reaching harmful unintended consequences, not just for medicine but for the broader world. Illustrating with discussion of three common pathways to experiences that applicants widely believe will help them gain admission, we describe how the construction ecology of medical school admissions can recast privilege as merit, reinforce colonizing narratives, and lead to exploitation of people who are already disadvantaged.

OBJECTIVE: Video-electroencephalography (vEEG) is an important component of epilepsy diagnosis and management. Nevertheless, inpatient vEEG monitoring fails to capture seizures in up to one third of patients. We hypothesized that personalized seizure forecasts could be used to optimize the timing of vEEG. METHODS: We used a database of ambulatory vEEG studies to select a cohort with linked electronic seizure diaries of more than 20 reported seizures over at least 8 weeks. The total cohort included 48 participants. Diary seizure times were used to detect individuals' multiday seizure cycles and estimate times of high seizure risk. We compared whether estimated seizure risk was significantly different between conclusive and inconclusive vEEGs, and between vEEG with and without recorded epileptic activity. vEEGs were conducted prior to self-reported seizures; hence, the study aimed to provide a retrospective proof of concept that cycles of seizure risk were correlated with vEEG outcomes. RESULTS: Estimated seizure risk was significantly higher for conclusive vEEGs and vEEGs with epileptic activity. Across all cycle strengths, the average time in high risk during vEEG was 29.1% compared with 14% for the conclusive/inconclusive groups and 32% compared to 18% for the epileptic activity/no epileptic activity groups. On average, 62.5% of the cohort showed increased time in high risk during their previous vEEG when epileptic activity was recorded (compared to 28% of the cohort where epileptic activity was not recorded). For conclusive vEEGs, 50% of the cohort had increased time in high risk, compared to 21.5% for inconclusive vEEGs. SIGNIFICANCE: Although retrospective, this study provides a proof of principle that scheduling monitoring times based on personalized seizure risk forecasts can improve the yield of vEEG. Forecasts can be developed at low cost from mobile seizure diaries. A simple scheduling tool to improve diagnostic outcomes may reduce cost and risks associated with delayed or missed diagnosis in epilepsy.

Epilepsy diagnosis can be costly, time-consuming, and not uncommonly inaccurate. The reference standard diagnostic monitoring is continuous video-electroencephalography (EEG) monitoring, ideally capturing all events or concordant interictal discharges. Automating EEG data review would save time and resources, thus enabling more people to receive reference standard monitoring and also potentially heralding a more quantitative approach to therapeutic outcomes. There is substantial research into the automated detection of seizures and epileptic activity from EEG. However, automated detection software is not widely used in the clinic, and despite numerous published algorithms, few methods have regulatory approval for detecting epileptic activity from EEG. This study reports on a deep learning algorithm for computer-assisted EEG review. Deep convolutional neural networks were trained to detect epileptic discharges using a preexisting dataset of over 6000 labelled events in a cohort of 103 patients with idiopathic generalized epilepsy (IGE). Patients underwent 24-hour ambulatory outpatient EEG, and all data were curated and confirmed independently by two epilepsy specialists (Seneviratne et al., 2016). The resulting automated detection algorithm was then used to review diagnostic scalp EEG for seven patients (four with IGE and three with events mimicking seizures) to validate performance in a clinical setting. The automated detection algorithm showed state-of-the-art performance for detecting epileptic activity from clinical EEG, with mean sensitivity of >95% and corresponding mean false positive rate of 1 detection per minute. Importantly, diagnostic case studies showed that the automated detection algorithm reduced human review time by 80%-99%, without compromising event detection or diagnostic accuracy. The presented results demonstrate that computer-assisted review can increase the speed and accuracy of EEG assessment and has the potential to greatly improve therapeutic outcomes.

BACKGROUND: Patients with advanced kidney disease are less likely than many patients with other types of serious illness to enroll in hospice. Little is known about real-world clinical decision-making related to hospice for members of this population. METHODS: We used a text search tool to conduct a thematic analysis of documentation pertaining to hospice in the electronic medical record system of the Department of Veterans Affairs, for a national sample of 1000 patients with advanced kidney disease between 2004 and 2014 who were followed until October 8, 2019. RESULTS: Three dominant themes emerged from our qualitative analysis of the electronic medical records of 340 cohort members with notes containing hospice mentions: (1) hospice and usual care as antithetical care models: clinicians appeared to perceive a sharp demarcation between services that could be provided under hospice versus usual care and were often uncertain about hospice eligibility criteria. This could shape decision-making about hospice and dialysis and made it hard to individualize care; (2) hospice as a last resort: patients often were referred to hospice late in the course of illness and did not so much choose hospice as accept these services after all treatment options had been exhausted; and (3) care complexity: patients' complex care needs at the time of hospice referral could complicate transitions to hospice, stretch the limits of home hospice, and promote continued reliance on the acute care system. CONCLUSIONS: Our findings underscore the need to improve transitions to hospice for patients with advanced kidney disease as they approach the end of life.

RATIONALE & OBJECTIVE: It is relatively unusual for US patients with advanced chronic kidney disease (CKD) to forgo initiation of maintenance dialysis. Our objective was to describe practice approaches of US nephrologists who have provided conservative care for members of this population. STUDY DESIGN: Qualitative study using semi-structured interviews. SETTING & PARTICIPANTS: A national sample of 21 nephrologists experienced in caring for patients with advanced CKD who decided not to start dialysis. ANALYTICAL APPROACH: Grounded theory methods to identify dominant themes reflecting nephrologists' experiences with and approaches to conservative care for patients with advanced CKD. RESULTS: Nephrologists who participated in this study were primarily from academic practices (n=14) and urban areas (n=15). Two prominent themes emerged from qualitative analysis reflecting nephrologists' experiences with and approaches to conservative care: (1) person-centered practices, which described a holistic approach to care that included basing treatment decisions on what mattered most to individual patients, framing dialysis as an explicit choice, being mindful of sources of bias in medical decision making, and being flexible to the changing needs, values, and preferences of patients; and (2) improvising a care infrastructure, which described the challenges of managing patients conservatively within health systems that are not optimally configured to support their needs. Participating nephrologists described cobbling together resources, assuming a range of different health care roles, preparing patients to navigate health systems in which initiation of dialysis served as a powerful default, and championing the principles of conservative care among their colleagues. LIMITATIONS: The themes identified likely are not generalizable to most US nephrologists. CONCLUSIONS: Insights from a select group of US nephrologists who are early adopters of conservative care signal the need for a stronger cultural and health system commitment to building care models capable of supporting patients who choose to forgo dialysis.

BACKGROUND: A potential pitfall of policies intended to promote referral for kidney transplant is that greater numbers of patients may be evaluated for transplant without experiencing the intended benefit of receiving a kidney. Little is known about the potential implications of this experience for patients. METHODS: We performed a thematic analysis of clinician documentation in the electronic medical records of all adults at a single medical center with advanced kidney disease who were referred to the local transplant coordinator for evaluation between 2008 and 2018 but did not receive a kidney. RESULTS: 148 of 209 patients referred to the local kidney transplant coordinator at our center (71%) had not received a kidney by the end of follow-up. Three dominant themes emerged from qualitative analysis of documentation in the medical records of these patients: 1) Forward momentum: patients found themselves engaged in an iterative process of testing and treatment that tended to move forward unless an absolute contraindication to transplant was identified or patients disengaged; 2) Potential for transplant shapes other medical decisions: engagement in the transplant evaluation process could impact many other aspects of patients' care; and 3) Personal responsibility and psychological burden for patients and families: clinician documentation suggested that patients felt personally responsible for the course of their evaluation and that the process could take an emotional toll on them and their family members. CONCLUSIONS: Engagement in the kidney transplant evaluation process can be a significant undertaking for patients and families and may impact many other aspects of their care. Policies to promote referral for kidney transplant should be coupled with efforts to strengthen shared decision-making to ensure that the decision to undergo transplant evaluation is framed as an explicit choice with benefits, risks, and alternatives and patients have an opportunity to shape their involvement in this process.

The box-office as well as critical success of the 2014 major motion picture Still Alice, starring Julianne Moore in the title role and based on the bestselling novel of the same name by the Harvard-trained neuroscientist Lisa Genova (Still Alice. Simon & Schuster, New York, 2009), marked an important moment in public cultural representations of people with dementia. Still Alice tells the story of Alice Howland, an eminent scientist whose increasing memory lapses are eventually diagnosed as early-onset Alzheimer's, and chronicles the transformations in her family relationships as her husband and three children respond to her decline in different ways. Alice's husband, her son, and her older daughter all respond by turning toward science, while her younger daughter Lydia seeks to engage her mother as she is now, and turns toward art and relationships. Taking Still Alice and the figure of Lydia as an entry point, I discuss arts-focused efforts to improve the lives of people with dementia, and draw upon ongoing interview-based research on the topic of dementia and friendship, to offer an account of some of the ways that people I have spoken with are actively experimenting with art and with relationships in the face of dementia. I argue that these efforts can be understood as "moral experiements," in the sense articulated by Cheryl Mattingly (Moral Laboratories: Family Peril and the Struggle for a Good Life. University of California Press, Berkeley, 2014). Although Lydia is a fictional character, her response to Alice's dementia points toward the kinds of moral experimentation that are in fact possible, and quietly being practiced, by ordinary people every day.

Importance: The second year of the COVID-19 pandemic saw periods of dire health care resource limitations in the US, sometimes prompting official declarations of crisis, but little is known about how these conditions were experienced by frontline clinicians. Objective: To describe the experiences of US clinicians practicing under conditions of extreme resource limitation during the second year of the pandemic. Design, Setting, and Participants: This qualitative inductive thematic analysis was based on interviews with physicians and nurses providing direct patient care at US health care institutions during the COVID-19 pandemic. Interviews were conducted between December 28, 2020, and December 9, 2021. Exposure: Crisis conditions as reflected by official state declarations and/or media reports. Main Outcomes and Measures: Clinicians' experiences as obtained through interviews. Results: Interviews with 23 clinicians (21 physicians and 2 nurses) who were practicing in California, Idaho, Minnesota, or Texas were included. Of the 23 total participants, 21 responded to a background survey to assess participant demographics; among these individuals, the mean (SD) age was 49 (7.3) years, 12 (57.1%) were men, and 18 (85.7%) self-identified as White. Three themes emerged in qualitative analysis. The first theme describes isolation. Clinicians had a limited view on what was happening outside their immediate practice setting and perceived a disconnect between official messaging about crisis conditions and their own experience. In the absence of overarching system-level support, responsibility for making challenging decisions about how to adapt practices and allocate resources often fell to frontline clinicians. The second theme describes in-the-moment decision-making. Formal crisis declarations did little to guide how resources were allocated in clinical practice. Clinicians adapted practice by drawing on their clinical judgment but described feeling ill equipped to handle some of the operationally and ethically complex situations that fell to them. The third theme describes waning motivation. As the pandemic persisted, the strong sense of mission, duty, and purpose that had fueled extraordinary efforts earlier in the pandemic was eroded by unsatisfying clinical roles, misalignment between clinicians' own values and institutional goals, more distant relationships with patients, and moral distress. Conclusions and Relevance: The findings of this qualitative study suggest that institutional plans to protect frontline clinicians from the responsibility for allocating scarce resources may be unworkable, especially in a state of chronic crisis. Efforts are needed to directly integrate frontline clinicians into institutional emergency responses and support them in ways that reflect the complex and dynamic realities of health care resource limitation.

The oncogenic receptor HER2 is overexpressed in many cancers, including up to 20% of breast cancers. Despite the availability of HER2-targeted treatments, patients' disease often progresses during therapy, underscoring the need for novel treatment strategies. The addition of tucatinib, a reversible, highly selective HER2 tyrosine kinase inhibitor (TKI), to treatment with trastuzumab and capecitabine significantly improved survival outcomes of patients with HER2-positive metastatic breast cancer, including those with active brain metastases. We rationalized that combining tucatinib with other HER2-targeting agents with complementary mechanisms of action would further increase efficacy against tumors. We characterized the activity of tucatinib with the antibodydrug conjugate T-DM1 in preclinical models of breast cancer, including HER2-positive breast cancer cells and patient-derived xenograft (PDX) models. Mechanistic details on tucatinib activity were obtained in internalization and catabolism studies. In combination, tucatinib and T-DM1 showed an enhanced, often synergistic, cytotoxic response and demonstrated improved antitumor activity in vivo, including in PDX models refractory to T-DM1 single-agent activity. Mechanistically, tucatinib mediated an increase in inactive HER2 molecules at the cell surface through inhibition of HER2 ubiquitination, resulting in increased internalization and catabolism of T-DM1. The combination was correlated with enhanced HER2 pathway inhibition, decreased proliferation, and increased apoptosis. In a xenograft model of brain metastasis, tucatinib penetrated intracranial tumor tissues, inhibiting tumor growth and improving survival. These results suggest that tucatinib may be the optimal TKI partner for HER2-targeted therapies and support clinical studies of its combination with T-DM1, including in patients with brain metastases. SIGNIFICANCE: The preclinical findings in breast cancer models presented here demonstrate that combining tucatinib with T-DM1 enhances the antitumor activity of either agent alone, supporting clinical studies of the combination in HER2-positive breast cancer, including in patients with brain metastases, which remains an important unmet medical need.

Ethnographic research with cognitively impaired older adults can be challenging, in part because cognitive impairment raises questions about the ability to provide informed consent. Relying on proxy consent is a commonly used strategy, but often excludes people with dementia who lack close kin (de Medeiros, Girling, & Berlinger, 2022). In this paper, we describe how we have analyzed existing research data from a well-established and ongoing prospective cohort study, the Adult Changes in Thought Study, along with unstructured text from the medical records of participants who had no living spouse or adult children when they developed dementia, as a way of studying the circumstances, life trajectories, caregiving resources, and care needs of this vulnerable and difficult-to-research group. In this article, we detail this methodology, exploring what can and cannot be gleaned from it, what the ethical implications may be, and how and whether this type of research can be considered ethnographic. In conclusion, we argue that collaborative interdisciplinary research using existing, longitudinal research data and text from medical records deserves to be considered as a potentially useful addition to the ethnographic toolkit. We anticipate that this is a methodology that could be applied more broadly, and paired with more traditional ethnographic methods, might be one way to make research with this population more inclusive.

OBJECTIVES: To examine the circumstances and needs of older adults who were "kinless," defined as having no living spouse or children, when they developed dementia. METHODS: We conducted a secondary analysis of information from the Adult Changes in Thought study. Among 848 participants diagnosed with dementia between 1994 and 2016, we identified 64 who had no living spouse or child at dementia onset. We then conducted a qualitative analysis of administrative documents pertaining to these participants: handwritten comments recorded after each study visit, and medical history documents containing clinical chart notes from participants' medical records. RESULTS: In this community-dwelling cohort of older adults diagnosed with dementia, 8.4% were kinless at dementia onset. Participants in this sample had an average age of 87 years old, half lived alone, and one third lived with unrelated persons. Through inductive content analysis, we identified 4 themes that describe their circumstances and needs: (1) life trajectories, (2) caregiving resources, (3) care needs and gaps, and (4) turning points in caregiving arrangements. DISCUSSION: Our qualitative analysis reveals that the life trajectories that led members of the analytic cohort to be kinless at dementia onset were quite varied. This research highlights the importance of nonfamily caregivers and participants' own roles as caregivers. Our findings suggest that clinicians and health systems may need to work with other parties to directly provide dementia caregiving support rather than rely on family, and address factors such as neighborhood affordability that particularly affect older adults who have limited family support.

Importance: Since 2014, when Congress passed the Veterans Access Choice and Accountability (Choice) Act (replaced in 2018 with the more comprehensive Maintaining Internal Systems and Strengthening Integrated Outside Networks [MISSION] Act), the Department of Veterans Affairs (VA) has been paying for US veterans to receive increasing amounts of care in the private sector (non-VA care or VA community care). However, little is known about the implications of these legislative changes for the VA system. Objective: To describe the implications for the VA system of recent increases in VA-financed non-VA care. Design, Setting, and Participants: This qualitative study was a thematic analysis of documentation in the electronic health records (EHRs) of a random sample of US veterans with advanced kidney disease between June 6, 2019, and February 5, 2021. Exposures: Mentions of community care in participant EHRs. Main Outcomes and Measures: Dominant themes pertaining to VA-financed non-VA care. Results: Among 1000 study participants, the mean (SD) age was 73.8 (11.4) years, and 957 participants (95.7%) were male. Three interrelated themes pertaining to VA-financed non-VA care emerged from qualitative analysis of documentation in cohort member EHRs: (1) VA as mothership, which describes extensive care coordination by VA staff members and clinicians to facilitate care outside the VA and the tendency of veterans and their non-VA clinicians to rely on the VA to fill gaps in this care; (2) hidden work of veterans, which describes the efforts of veterans and their family members to navigate the referral process, and to serve as intermediaries between VA and non-VA clinicians; and (3) strain on the VA system, which describes a challenging referral process and the ways in which cross-system care has stretched the traditional roles of VA staff and clinicians and interfered with VA care processes. Conclusions and Relevance: The findings of this qualitative study describing VA-financed non-VA care for veterans with advanced kidney disease spotlight the substantial challenges of cross-system use and the strain placed on the VA system, VA staff and clinicians, and veterans and their families in recent years. These difficult-to-measure consequences of cross-system care should be considered when budgeting, evaluating, and planning the provision of VA-financed non-VA care in the private sector.

Importance: There is increasing recognition of the long-term health effects of SARS-CoV-2 infection (sometimes called long COVID). However, little is yet known about the clinical diagnosis and management of long COVID within health systems. Objective: To describe dominant themes pertaining to the clinical diagnosis and management of long COVID in the electronic health records (EHRs) of patients with a diagnostic code for this condition (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10] code U09.9). Design, Setting, and Participants: This qualitative analysis used data from EHRs of a national random sample of 200 patients receiving care in the Department of Veterans Affairs (VA) with documentation of a positive result on a polymerase chain reaction (PCR) test for SARS-CoV-2 between February 27, 2020, and December 31, 2021, and an ICD-10 diagnostic code for long COVID between October 1, 2021, when the code was implemented, and March 1, 2022. Data were analyzed from February 5 to May 31, 2022. Main Outcomes and Measures: A text word search and qualitative analysis of patients' VA-wide EHRs was performed to identify dominant themes pertaining to the clinical diagnosis and management of long COVID. Results: In this qualitative analysis of documentation in the VA-wide EHR, the mean (SD) age of the 200 sampled patients at the time of their first positive PCR test result for SARS-CoV-2 in VA records was 60 (14.5) years. The sample included 173 (86.5%) men; 45 individuals (22.5%) were identified as Black and 136 individuals (68.0%) were identified as White. In qualitative analysis of documentation pertaining to long COVID in patients' EHRs 2 dominant themes were identified: (1) clinical uncertainty, in that it was often unclear whether particular symptoms could be attributed to long COVID, given the medical complexity and functional limitations of many patients and absence of specific markers for this condition, which could lead to ongoing monitoring, diagnostic testing, and specialist referral; and (2) care fragmentation, describing how post-COVID-19 care processes were often siloed from and poorly coordinated with other aspects of care and could be burdensome to patients. Conclusions and Relevance: This qualitative study of documentation in the VA EHR highlights the complexity of diagnosing long COVID in clinical settings and the challenges of caring for patients who have or are suspected of having this condition.

Standardized patient (SP) performances are staged clinical encounters between health-professional students and people who specialize in role-playing the part of patients. Such performances have in recent years become increasingly central to the teaching and assessment of clinical skills in U.S. medical schools. SP performances are valued for being both "real" (in that they involve interaction with a real person, unlike written examinations) and "not real" (in that the SP does not actually suffer from the condition portrayed, unlike an actual patient). This article considers how people involved in creating SP performances reconcile a moral commitment to avoid suffering (to keep it "not real"), with an aesthetic commitment to realistically portray it (to keep it "real"). The term "moral aesthetic" is proposed, to indicate a sensibility that combines ideas about what is morally right with ideas about what is aesthetically compelling. Drawing on ethnographic research among SPs and SP program staff and medical faculty who work closely with them, this article argues that their work of creating "realism" in simulated clinical encounters encompasses multiple different (and sometimes conflicting) understandings and practices of realism, informed by three different moral aesthetics: (1) a moral aesthetic of induction, in which an accurate portrayal with a well-documented provenance serves to introduce experientially distant forms of suffering; (2) a moral aesthetic of inoculation, in which the authenticity and emotional impact of a performance are meant to inoculate students against the impact of future encounters with suffering; (3) a moral aesthetic of presence, generating forms of voice and care that are born out of the embodied presence of suffering individuals in a clinical space. All are premised on the assumption that risk and suffering can be banished from SP performances. This article suggests, however, that SP performances necessarily raise the same difficult, important, fundamentally ethical questions that are always involved in learning from and on human beings who are capable of suffering, and who need and deserve recognition and respect as well as care.

Importance: To be considered for a kidney transplant, patients with advanced kidney disease must participate in a formal evaluation and selection process. Little is known about how this process proceeds in real-world clinical settings. Objective: To characterize the transplant evaluation process among a representative national sample of US veterans with advanced kidney disease who were referred to a kidney transplant center. Design, Setting, and Participants: This qualitative study was a thematic analysis of clinician notes in the electronic health records of US veterans referred for kidney transplant evaluation. In a random sample of 4000 patients with advanced kidney disease between January 1, 2004, and December 31, 2014, cared for in the US Department of Veterans Affairs (VA) health care system, there were 211 patients who were referred to a transplant center during the follow-up period. This group was included in the qualitative analysis and was followed up until their date of death or the end of the follow-up period on October 8, 2019. Main Outcomes and Measures: Dominant themes pertaining to the kidney transplant evaluation and selection process identified through thematic analysis. Results: Among 211 study patients, the mean (SD) age was 57.9 (9.5) years, and 202 patients (95.7%) were male. The following 4 dominant themes regarding the transplant evaluation process emerged: (1) far-reaching and inflexible medical evaluation, in which patients were expected to complete an extensive evaluation that could have substantial physical and emotional consequences, made little accommodation for their personal values and needs, and impacted other aspects of their care; (2) psychosocial valuation, in which the psychosocial component of the transplant assessment could be subjective and intrusive and could place substantial demands on patients' family members; (3) surveillance over compliance, in which the patients' ability and willingness to follow medical recommendations was an important criterion for transplant candidacy and their adherence to a wide range of recommendations and treatments was closely monitored; and (4) disempowerment and lack of transparency, in which patients and their local clinicians were often unsure about what to expect during the evaluation process or about the rationale for selection decisions. For the evaluation process to proceed, local clinicians had to follow transplant center requirements even when they believed the requirements did not align with best practices or the patients' needs. Conclusions and Relevance: In this qualitative study of US veterans with advanced kidney disease evaluated for transplant, clinician documentation in the medical record indicated that, to be considered for a kidney transplant, patients were required to participate in a rigid, demanding, and opaque evaluation and selection process over which they and their local clinicians had little control. These findings highlight the need for a more evidence-based, individualized, and collaborative approach to kidney transplant evaluation.

BACKGROUND: United States hospice organizations aim to provide quality, patient-centered end-of-life care to patients in the last 6 months of life, yet some of these organizations observe that some hospice-eligible patients who are referred to hospice do not initially enroll. PRIMARY OBJECTIVE: To identify reasons that eligible patients do not enroll in hospice (phase 1). SECONDARY OBJECTIVE: To identify strategies used by hospice providers to address these reasons (phase 2). DESIGN: Semi-structured interviews analyzed using content analysis. PARTICIPANTS: In phase 1, we interviewed 30 patients and/or family members of patients who had a hospice admissions visit, but who did not enroll. In phase 2, we interviewed 19 hospice staff and national experts. APPROACH: In phase 1, we asked participants to describe the patient's illness, the hospice referral, and why they had not enrolled. We performed a content analysis to characterize their reasons for not enrolling in hospice. In phase 2, we enrolled hospice admissions staff and hospice experts. We asked them to describe how they would respond to each reason (from phase 1) during an admissions visit with a potential new hospice patient. We identified key phrases, and summarized their recommendations. RESULTS: Reasons that patients hadn't enrolled fell into three broad categories: patient/family perceptions (e.g., "not ready"), hospice specific issues (e.g., variable definitions of hospice-eligible patients), and systems issues (e.g., concerns about continuity of care). Hospice staff/experts had encountered each reason, and offered strategies at the individual and organizational level for responding. CONCLUSIONS: In hopes of increasing hospice enrollment among hospice-eligible patients, non-hospice and hospice clinicians may want to adopt some of the strategies used by hospice staff/experts for talking about hospice with patients/families and may want to familiarize themselves with the differences between hospice organizations in their area. Hospices may want to reconsider their admission policies and procedures in light of patients' and families' perceptions and concerns.

HER2 is a transmembrane tyrosine kinase receptor that mediates cell growth, differentiation, and survival. HER2 is overexpressed in approximately 20% of breast cancers and in subsets of gastric, colorectal, and esophageal cancers. Both antibody and small-molecule drugs that target HER2 and block its tyrosine kinase activity are effective in treating HER2-driven cancers. In this article, we describe the preclinical properties of tucatinib, an orally available, reversible HER2-targeted small-molecule tyrosine kinase inhibitor. In both biochemical and cell signaling experiments, tucatinib inhibits HER2 kinase activity with single-digit nanomolar potency and provides exceptional selectivity for HER2 compared with the related receptor tyrosine kinase EGFR, with a >1,000-fold enhancement in potency for HER2 in cell signaling assays. Tucatinib potently inhibits signal transduction downstream of HER2 and HER3 through the MAPK and PI3K/AKT pathways and is selectively cytotoxic in HER2-amplified breast cancer cell lines in vitro. In vivo, tucatinib is active in multiple HER2+ tumor models as a single agent and shows enhanced antitumor activity in combination with trastuzumab or docetaxel, resulting in improved rates of partial and complete tumor regression. These preclinical data, taken together with the phase-I tucatinib clinical trial results demonstrating preliminary safety and activity, establish the unique pharmacologic properties of tucatinib and underscore the rationale for investigating its utility in HER2+ cancers.

The present study compared parent ratings to self-report ratings of depression, anxiety, hyperactivity, attention problems, and atypical behaviors in youth with high-functioning autism spectrum disorder (HFASD) and typically developing (TD) controls. Measures included parent and self-report forms from the Behavioral Assessment System for Children-Second Edition (BASC-2), and self-report forms from the Children's Depression Inventory (CDI) and the Multidimensional Anxiety Scale for Children (MASC). Results across all five BASC-2 scales indicated parent ratings for the HFASD condition were significantly higher than HFASD self-ratings, and were significantly higher than parent and self-ratings from the TD condition. In addition, average self-report scores did not differ significantly between HFASD and TD conditions on any of the BASC-2 scales, the CDI, or the MASC.

Importance: Prognostic understanding can shape patients' treatment goals and preferences. Patients undergoing dialysis in the United States have limited life expectancy and may receive end-of-life care directed at life extension. Little is known about their prognostic expectations. Objective: To understand the prognostic expectations of patients undergoing dialysis and how these relate to care planning, goals, and preferences. Design, Setting, and Participants: Cross-sectional survey study of 996 eligible patients treated with regular dialysis at 31 nonprofit dialysis facilities in 2 metropolitan areas (Seattle, Washington, and Nashville, Tennessee) between April 2015 and October 2018. After a pilot phase, 1434 eligible patients were invited to participate (response rate, 69.5%). To provide a context for interpreting survey participants' prognostic estimates, United States Renal Data System standard analysis files were used to construct a comparison cohort of 307â¯602 patients undergoing in-center hemodialysis on January 1, 2006, and followed for death through July 31, 2017. Final analyses for this study were conducted between November 2018 and March 2019. Exposures: Responses to the question "How long would you guess people your age with similar health conditions usually live?" (<5 years, 5-10 years, >10 years, or not sure). Main Outcomes and Measures: Self-reported (1) documentation of a surrogate decision-maker, (2) documentation of treatment preferences, (3) values around life prolongation, (4) preferences for receipt of cardiopulmonary resuscitation and mechanical ventilation, and (5) desired place of death. Results: Of the 996 survey respondents, the mean (SD) age was 62.7 (13.9) years, and 438 (44.0%) were women. Overall, 112 (11.2%) survey respondents selected a prognosis of fewer than 5 years, 150 (15.1%) respondents selected 5 to 10 years, 330 (33.1%) respondents selected more than 10 years, and 404 (40.6%) were not sure. By comparison, 185â¯427 (60.3%) prevalent US in-center patients undergoing hemodialysis died within 5 years, 58â¯437 (19.0%) died within 5 to 10 years, and 63â¯738 (20.7%) lived more than 10 years. In analyses adjusted for participant characteristics, survey respondents with a prognostic expectation of more than 10 years (vs <5 years) were less likely to report documentation of a surrogate decision-maker (adjusted odds ratio [aOR], 0.6; 95% CI, 0.4-0.9) and treatment preferences (aOR, 0.4; 95% CI, 0.2-0.6) and to value comfort over life extension (aOR, 0.1; 95% CI, 0.04-0.3), and were more likely to want cardiopulmonary resuscitation (aOR, 5.3; 95% CI, 3.2-8.7) and mechanical ventilation (aOR, 2.2; 95% CI, 1.2-3.7). The respondents who reported that they were not sure about prognosis had similar associations. Conclusions and Relevance: Uncertain and overly optimistic prognostic expectations may limit the benefit of advance care planning and contribute to high-intensity end-of-life care in patients undergoing dialysis.
