Abstraction to a single prototypical representation is a coreprinciple of Distributional Semantic Models (DSMs) thatlearn semantic representations for words by applyingdimension reduction to statistical redundancies in language.While the learning mechanisms for semantic abstraction varywidely across the many DSMs in the literature, they areessentially all prototype models in that they create a singleabstract representation for a word’s meaning. The prototypemethod stands in stark contrast to work in the field ofcategorization that has converged on the importance ofinstance models. In comparison to the prototype method,instance-based models assume only an episodic store and,rather than applying abstraction mechanisms at learning,argue that meaning emerges in the act of retrieval. We cashthis idea out by presenting and evaluating an instance theoryof distributional semantics, and by demonstrating that it canexplain diverging patterns of homonymous words that classic“abstraction-at-learning” models simply cannot as aconsequence of their architectural assumptions.

Young adults (YAs), defined as individuals between the ages of 18 and 39 years, experience unique challenges when diagnosed with advanced cancer. Using the social constructivist grounded theory approach, we aimed to develop a theoretical understanding of how YAs live day to day with their diagnosis. A sample of 25 YAs (aged 22–39 years) with advanced cancer from across Canada participated in semi-structured interviews. Findings illustrate that the YAs described day-to-day life as an oscillating experience swinging between two opposing disease outcomes: (1) hoping for a cure and (2) facing the possibility of premature death. Oscillating between these potential outcomes was characterized as living in a liminal space wherein participants were unsure how to live from one day to the next. The participants oscillated at various rates, with different factors influencing the rate of oscillation, including inconsistent and poor messaging from their oncologists or treatment team, progression or regression of their cancer, and changes in their physical functioning and mental health. These findings provide a theoretical framework for designing interventions to help YAs adapt to their circumstance. [ABSTRACT FROM AUTHOR]

Purpose: Caregivers of patients with cancer cope with socioemotional challenges, which can adversely affect their well-being. We developed an intervention, expressive writing and reading (EWR), to promote emotional processing and social connectedness among caregivers. In a single-arm pilot study, we assessed its feasibility and perceived usefulness. Methods: Caregivers participated in weekly 1.5-hour EWR workshops offered over 20 weeks. After 4 sessions, they completed semistructured interviews, which were analyzed using qualitative descriptive analysis. Findings: Of 65 caregivers approached, 25 were eligible, 18 consented, and 9 (50%) caregivers completed at least 4 workshops and the interview. Their responses revealed 3 themes: "inner processing," "interpersonal learning," and "enhanced processing and preparedness." Perceived benefits of EWR included emotional and cognitive processing (individual and collaborative), learning from the emotions and experiences of other caregivers, and preparing for upcoming challenges. Conclusions: Expressive writing and reading can be a safe and cost-effective supportive intervention for caregivers of patients with cancer. [ABSTRACT FROM AUTHOR]

In cancer care, gaps in support to help patients manage and live with the side-effects from cancer treatments have increased the emphasis on empowering patients to be more active and involved in managing their own health. However, empowerment in relation to promoting self-management behaviors is not well understood. Using the social constructivist grounded theory approach, our goal was to develop a theoretical understanding of this phenomenon in relation to the self-management behaviors of post-treatment cancer patients. Twenty-two post-treatment cancer patients participated in a semi-structured focused interview to co-construct with us how empowerment is defined, described, and experienced in relation to their capacity to self-manage. Through this co-construction, we defined empowerment as a process of personal growth, a display of fortitude and strength when participants confronted the impact of their illness that emerged in two dynamic and paradoxical ways: 1) establishing control over the impact of the illness as a means to maintain normalcy and to circumvent change over an eroding and changing sense of self and 2) relinquishing control over aspects of the illness deemed irrepressible and acknowledging and accepting change. When successful at establishing and/or relinquishing control, participants no longer viewed cancer as a threat, but re-interpreted their illness as also having a beneficial "empowering" experience and more capable of managing. Findings will guide the development of self-management interventions that use empowerment as a core construct. [ABSTRACT FROM AUTHOR]

Background: Age-related complex medical conditions have been commonly reported among adolescents and young adults with advanced life-limiting illness. There is increasing interest in exploring their palliative care needs and end-of-life experiences. Aim: This scoping review aimed to explore the available literature about providing palliative and end-of-life care to adolescents and young adults with advanced life-limiting illnesses. Design: Scoping review. This review was registered on Open Science Framework (https://doi.org/10.17605/OSF.IO/SPTD7). Data sources: Electronic databases (MEDLINEALL, Embase, Emcare, Cochrane Central Register of Controlled Trial CENTRAL, Scopus, PsycINFO, Cochrane Database of Systematic Reviews), Google Scholar and reference lists were searched up to October 2021. We included studies reporting on adolescents and/or young adults with advanced life-limiting illnesses. There were no limitations concerning location, type of illness or study design. Results: We identified 51 studies published between 2002 and 2021. Most studies were published in the United States (n = 34, 67%), and nine studies (18%) reported exclusively on patients with non-malignant illnesses. Two thirds of the identified studies were case reports and retrospective chart reviews (n = 33). Three main topics were identified: Physical symptom burden (n = 26, 51%), Psychological and social needs (n = 33, 65%), and end-of-life care (n = 30, 59%). Twenty-six studies (51%) were focused only on one topic, and the age range used to identify adolescents and young adults varied based on the study location. Conclusion: The findings of this review shed light on the different palliative care experiences and knowledge gaps related to adolescents and young adults as an underserved and vulnerable patient population. Further research needs to be dedicated toward palliative care programs tailored for adolescents and young adults. [ABSTRACT FROM AUTHOR]

Adolescents and young adult (AYA) oncology care has evolved to address their unique supportive care needs, yet deficiencies remain. We planned a multiphase sequential mixed methods study beginning with focus groups (FGs) with AYAs receiving care at the Princess Margaret Cancer Centre, to improve supportive care delivery. Herewith, we report on the preliminary findings from first phase of project and outline future expected goals. Our findings suggest four major themes identified from FG discussion with AYAs: (1) having peer-driven support, (2) incorporating hybrid approach to information delivery, (3) integrating general practitioners in AYAs care, and (4) providing AYAs-specific supportive care programs.

Background: Due to ongoing disparity in the specialized care available to adolescents and young adults (AYAs) with cancer, this study aimed to understand the gaps and barriers to accessing care and preferences on types of solutions at a national Canadian level. Methods: A mixed-methods study involving an online survey and focus groups (FGs) was conducted among AYAs residing in different regions of Canada. Results: There were a total of 174 survey respondents, of whom the majority were between 30–39 years of age (n = 125, 71.8%). Of the 174 respondents, 36 (20.7%) participated in one of seven FGs. Triangulation of the results illustrated that AYAs are not appropriately informed about the long-term health risks of being treated for cancer and where/how to seek support. These results culminated into three themes: (1) the need for AYA relevant and timely information about health risks; by (a) producing health risk-related content with the AYA life stage in mind; (b) providing a guided "map" to help AYAs anticipate what they may experience, and (c) providing checklists to help AYAs navigate their experience; (2) need for tailored and timely supportive care including (a) establishing ongoing check-ins and (b) receiving navigation support, and (3) need for enhanced connections by creating (a) a space to gather, connect and seek mentorship and (b) a hub to access information. Conclusion: AYAs continue to lack sufficient support both during and following cancer and mechanisms are required to ensure longitudinal support is provided across jurisdictions and in all stages of the cancer journey.

Colorectal cancer (CRC) can be demanding for primary caregivers; yet, there is insufficient evidence describing the caregiver-reported outcomes (CROs) that matter most to caregivers. CROs refer to caregivers’ assessments of their own health status as a result of supporting a patient. The study purpose was to describe the emotions that were most impactful to caregivers of patients with CRC, and how the importance caregivers attribute to these emotions changed from diagnosis throughout treatment. Guided by qualitative Interpretive Description, we analyzed 25 caregiver and 37 CRC patient interviews, either as individuals or as caregiver-patient dyads (six interviews), using inductive coding and constant comparative techniques. We found that the emotional aspect of caring for a patient with CRC was at the heart of caregiving. Caregiver experiences that engendered emotions of consequence included: (1) facing the patient’s life-changing diagnosis and an uncertain future, (2) needing to be with the patient throughout the never-ending nightmare of treatment, (3) bearing witness to patient suffering, (4) being worn down by unrelenting caregiver responsibilities, (5) navigating their relationship, and (6) enduring unwanted change. The broad range of emotions important to caregivers contributes to comprehensive foundational evidence for future conceptualization and the use of CROs. [ABSTRACT FROM AUTHOR]

Racial disparities in conviction and incarceration have been lamentable features of legal systems for a long time. Research has addressed the attitudes and decisions of police, prosecutors, jurors, and judges in contributing to these disparities, but very little attention has been paid to defendants' own team members—i.e., criminal defense attorneys. Researchers have specifically identified this as a "scholarly gap". To address this, we conducted an empirical study of criminal defense attorneys practicing in forty-three U.S. states (N = 327). The attorneys completed both an implicit measure designed to capture racial bias (a race Implicit Association Test) and an explicit measure designed to capture interpersonal regard for clients. The results provided support for longstanding, but previously speculative, assertions of bias in criminal defense. [ABSTRACT FROM AUTHOR]

Objectives: Despite calls for better supportive care, patients and families still commonly bear significant responsibility for managing the physical and mental health and social challenges of being diagnosed with and treated for cancer. As such, there is increased advocacy for integrated supportive care to ease the burden of this responsibility. The purpose of this study was to understand patient and caregiver experiences with supportive care to advance its delivery at a large provincial cancer care organization in Canada. Method: We used a qualitative descriptive approach to analyze focus groups with patients and caregivers from seven sites across the large provincial cancer care organization. Results: Focus group participants (n = 69) included cancer patients (n = 57) and caregivers (n = 12). Participants highlighted positive and negative aspects of their experience and strategies for improvement. These are depicted in three themes: (1) improving patient and provider awareness of services; (2) increasing access; (3) enhancing coordination and integration. Participants’ specific suggestions included centralizing relevant information about services, implementing a coach or navigator to help advocate for access, and delivering care virtually. Conclusions: Participants highlighted barriers to access and made suggestions for improving supportive care that they believed would reduce the burden associated with trying to manage their cancer journey.

Background: Medical Assistance in Dying comprises interventions that can be provided by medical practitioners to cause death of a person at their request if they meet predefined criteria. In June 2016, Medical Assistance in Dying became legal in Canada, sparking intense debate in the palliative care community. Aim: This study aims to explore the experience of frontline palliative care providers about the impact of Medical Assistance in Dying on palliative care practice. Design: Qualitative descriptive design using semi-structured interviews and thematic analysis Settings/participants: We interviewed palliative care physicians and nurses who practiced in settings where patients could access Medical Assistance in Dying for at least 6 months before and after its legalization. Purposeful sampling was used to recruit participants with diverse personal views and experiences with assisted death. Conceptual saturation was achieved after interviewing 23 palliative care providers (13 physicians and 10 nurses) in Southern Ontario. Results: Themes identified included a new dying experience with assisted death; challenges with symptom control; challenges with communication; impact on palliative care providers personally and on their relationships with patients; and consumption of palliative care resources to support assisted death. Conclusion: Medical Assistance in Dying has had a profound impact on palliative care providers and their practice. Communication training with access to resources for ethical decision-making and a review of legislation may help address new challenges. Further research is needed to understand palliative care provider distress around Medical Assistance in Dying, and additional resources are necessary to support palliative care delivery.

PURPOSE Young adults (YAs; defined as 18-39 years of age) with advanced cancer are a group for whom standardized age-appropriate palliative care has not been established. The purpose of this study was to explore the YA experience and perceptions of palliative care in an outpatient interdisciplinary palliative care clinic for this population. PATIENTS AND METHODS Using an interpretive descriptive design, semistructured interviews were conducted with 12 YAs with advanced cancer who were being seen jointly by a palliative care physician and psychiatrist in an ambulatory palliative care clinic. Interviews explored participants' understanding and experiences of receiving palliative care. Six family members were also interviewed to build on the YA experience. Data collection and analysis occurred concurrently, drawing on the constructivist grounded theory method to analyze the data. RESULTS Participants described being referred to and seen in the interdisciplinary palliative care clinic as a conflicting and at times difficult experience because of the feeling of being categorized as palliative as YAs. Even so, there were key aspects associated with the specific palliative care approach that allowed YAs to cope with this new label, leading to a beneficial experience, specifically: provided YAs with time and space to explore the experience of having cancer at a younger age, created repeat opportunities to talk openly with people who "got it," and highlighted the importance of including family support in the care of YAs. CONCLUSION YAs who were referred to the interdisciplinary palliative care clinic struggled with the category of palliative care but also found the care they received beneficial. Findings provide an approach to palliative care tailored to YAs with advanced cancer. [ABSTRACT FROM AUTHOR]

Background and Objectives: Addiction is increasingly considered a chronic, relapsing brain disease; however, many scholars still disagree with the brain disease model of addiction. We set out to provide evidence of attorneys' and physicians' beliefs regarding the model. First, we asked the following question: do attorneys and physicians affirm the full brain disease model, or its modified form, or do they believe that addiction is driven by deficits in self-control or moral weakness? Second, we evaluated the extent to which such beliefs correspond to attitudes toward individuals with substance use disorders (SUDs).Methods: A questionnaire was sent to resident physicians (N = 301) and criminal defense attorneys (N = 483) practicing in the United States. It was comprised of (i) an attitudes measure, (ii) a measure regarding conceptions of addiction, and (iii) demographic questions.Results: Attorneys were more likely to believe that individuals with SUDs had "practically no choice" about whether to seek and use, whereas physicians were more likely to believe that such individuals had "genuine choice." For both groups of participants, the rejection of the full brain disease model of addiction was associated with more negative attitudes toward individuals with SUDs.Conclusion and Scientific Significance: These results represent an important advance, as past research has neglected attorneys' attitudes and is inconclusive regarding the manner in which beliefs about the brain disease model of addiction are related to attitudes toward individuals with SUDs. Educating practitioners regarding this relationship would raise awareness regarding when and to what extent stigma is likely to be present, which may in turn provide a foundation from which to address stigma.

PURPOSE: Adolescents and young adults (AYAs; age 15-39 years) with advanced cancer are a population in whom quality of life is uniquely affected because of their stage of life. However, training focused on palliative care for AYAs is not routinely provided for health care providers (HCPs) in oncology. This study aims to explore the experiences of HCPs involved in introducing and providing palliative care caring for AYAs with advanced cancer and their families to understand the unique challenges HCPs experience. METHODS: Using a qualitative descriptive design, semistructured interviews were conducted with medical and radiation oncologists, palliative care physicians, psychiatrists, and advanced practice nurses involved in caring for AYAs diagnosed with advanced cancer (N = 19). Interviews were transcribed verbatim and analyzed using thematic analysis in combination with constant comparative analysis and theoretical sampling. RESULTS: There were 19 participants, 9 men and 10 women, with a median age of 45 years (range, 24-67 years). Six were palliative care physicians, 5 medical oncologists, 4 nurse practitioners, and 2 each radiation oncologists and psychiatrists. Overall, participants perceived the provision of palliative care for AYAs to be more difficult compared with older adults. Four themes emerged: (1) challenges helping AYAs/families to engage in and accept palliative care, (2) uncertainty regarding how to involve the family, (3) HCP sense of tragedy, and (4) HCP sense of emotional proximity. CONCLUSION: Findings from this study support the development of dedicated training for HCPs involved in palliative care for AYA. [ABSTRACT FROM AUTHOR]

This commentary refers to the article "Targeted Oral Naltrexone for Mild to Moderate Alcohol Use Disorder Among Sexual and Gender Minority Men: A Randomized Trial," by G-M. Santos, J. Ikeda, P. Coffin and colleagues, that was published within the issue. Topics discussed include efficacy and tolerability of topiramate and other medications for the treatment of alcohol use disorder (AUD), clinical practice guidelines for the pharmacological treatment of AUD, and side effects from naltrexone.

Background and Objectives: While a large percentage of criminal offenders suffer from substance use disorders (SUDs), virtually nothing is known about the attitudes criminal defense attorneys possess toward their clients who are facing substance-related charges. This is a serious concern, as the burden of steering individuals with SUDs into treatment often falls to criminal defense attorneys. The goal of this study was to examine the attitudes of criminal defense attorneys toward individuals who have been accused of drug crimes.Methods: A questionnaire was sent to criminal defense attorneys (N = 1,933) from all 50 U.S. states and the District of Columbia. It was comprised of (i) demographic information and (ii) a version of the 11-item Medical Condition Regard Scale (MCRS).Results: Criminal defense attorneys held generally positive attitudes toward clients with substance-related charges, but there was a significant divergence in attitudes between private and public attorneys, with the latter showing both greater familiarity with and better attitudes toward this same group of clients. These differences were impactful: worse attitudes toward clients strongly correlated with greater predictions that the clients would reoffend.Conclusion and Scientific Significance: Given the magnitude of the incarcerated population with SUDs and the centrality of defense attorneys in the treatment process, especially its initiation, the divergence in attitudes between private and public criminal defense attorneys is concerning. There is a clear need for increased collaboration between physicians and attorneys, with an aim of increasing the number of individuals with SUDs receiving proper treatment (Am J Addict 2018;XX:1-7).
