Role of Uncertainty in Illness and Coping Strategies in Advance Directive Completion in Patients With End-stage Liver Disease.

OBJECTIVE: We examined the associations among advance directives (ADs) completion, coping, uncertainty in illness, and optimism and pessimism in patients with end-stage liver disease (ESLD). BACKGROUND: Although associations among ADs, coping, and uncertainty have been studied in patients with other life-limiting illnesses, these concepts have not been studied together in patients with ESLD. PATIENTS AND METHODS: Patients were recruited at 2 health care institutions as part of a larger prospective study. They were enrolled if they had a diagnosis of nonhepatocellular carcinoma ESLD, Sodium Model for End-Stage Liver Disease ≥15, and no prior history of liver transplantation. Uncertainty, coping, optimism, and pessimism were assessed using the Uncertainty in Illness Scale for Adults, Revised Ways of Coping Checklist, and Life Orientation Test-revised. AD documentation at the time of study enrollment was retrospectively extracted from patient medical records. RESULTS: In the sample [N = 181; median age = 57 y, 115 (64%) males], male sex [odds ratio (OR) = 4.66; 95% CI: 1.53, 14.17], being listed or under evaluation for liver transplantation (OR = 3.09; 95% CI: 1.10, 8.67), greater Sodium Model for End-Stage Liver Disease scores (OR = 1.10; 95% CI: 1.01, 1.20), and greater uncertainty (OR = 1.04; 95% CI: 1.01, 1.07) were positively associated with AD documentation. Higher coping avoidance was negatively associated with AD documentation (OR = 0.915; 95% CI: 0.840, 0.997). CONCLUSIONS: Clinicians should consider the role of uncertainty and coping measures to improve patient-specific advance care planning conversations and expand opportunities for all patients with ESLD to file an AD, especially women and patients not listed or under evaluation for transplantation.

Preliminary effects of a yoga intervention for lung cancer dyads: benefits for care partners.

PURPOSE: Lung cancer is a disease with high mortality and morbidity, impacting both the patient and their closest contact, referred to in this paper as their care partner. There is limited evidence on how to support mental health and quality of life (QOL) for patient-care partner dyads during cancer treatment. This pilot study examines yoga as an intervention to improve well-being for the dyad. METHODS: A single-group, 12-week pilot trial of yoga for patients and their care partners recruited from two hospitals during cancer treatment (N = 23 patient-partner dyads or 46 individuals). Most care partners were spouses (70%), with the remainder being adult children (22%), a sibling (4%), or a friend (4%). Descriptive statistics, Cohen's d effect sizes, and paired t-tests for validated psychosocial measures were calculated at baseline and 12 weeks. RESULTS: Sixty-five percent of dyads (N = 13) completed the study, with withdrawals mostly due to disease progression. Among care partners, there was a decrease in depression symptomology on the PHQ-8 (p = 0.015, Cohen's d = 0.96) and improvement in QOL on the Caregiver QOL-Cancer scale (p = 0.001, Cohen's d = 0.61). Fifty percent of dyads experienced concordant improvement in depressive symptoms and 77% in QOL. CONCLUSION: Patient-partner yoga is a promising intervention for improving mental health and QOL for patient-partner dyads among lung cancer survivors. This study demonstrates yoga to be acceptable, feasible, and with high concordance within patient-partner dyads for improvements in QOL. Yoga shows promise for patients and care partners to alleviate the negative psychosocial impacts of lung cancer, though more research is needed to confirm effects.

Maternal depression, parenting, and child psychological outcomes in the context of maternal pain.

Parental chronic pain is associated with adverse outcomes in children, but the mechanisms of transmission are largely untested. Mothers with chronic pain (N = 400, Mage = 40.3 years, 90.5% White) and their children (Mage = 10.33 years, 83.3% White, 50.2% female) were recruited in 2016-2018 to test longitudinal pathways of risk transmission from maternal chronic pain to children's psychological symptoms, examining roles of parenting, maternal depression, and child distress tolerance. Maternal pain was associated with positive (ß = .28) and pain-specific (ß = .10) parenting behaviors. Maternal depression was associated with lower child distress tolerance (ß = -.03), which was associated with greater child psychological symptoms (ß = -.62). Parenting and maternal pain were not prospectively associated with child outcomes. When considering the dual-generational impacts of chronic pain, physical and psychological functioning should be examined.

Assessment of Mobility Trajectories Using Wearable Inertial Sensors During Autologous Hematopoietic Cell Transplant.

OBJECTIVE: This study aimed to characterize mobility patterns using wearable inertial sensors and serial assessment across autologous hematopoietic cell transplant (autoHCT) and investigate the relation between mobility and perceived function in patients with hematologic cancer. DESIGN: Prospective longitudinal study. SETTING: Hospital adult transplant clinic followed by discharge. PARTICIPANTS: 78 patients with hematological cancer receiving autoHCT. MAIN OUTCOME MEASURES: Mobility was measured across 3 clinical phases (pretransplant, pre-engraftment, and post-engraftment) in using inertial sensors worn during prescribed performance tests in the hospital. Perceived function was assessed using validated provider-reported (Eastern Cooperative Oncology Group [ECOG] Performance Status Scale) and patient-reported [European Organization for Research and Treatment of Cancer Quality of Life Questionnaire [EORTC QLQ-C30]) measures. Trajectories of 5 selected mobility characteristics (turn duration, gait speed, stride time variability, double support time, and heel strike angle) across the clinical phases were also evaluated using piecewise linear mixed-effects models. RESULTS: Using Principal Components Analysis, 4 mobility patterns were identified pretransplant: Gait Limitation, Sagittal Sway, Coronal Sway, and Balance Control. Gait Limitation measured pretransplant was significantly inversely associated with perceived function reported by the provider- (ß = -0.11; 95% CI: -0.19, -0.02) and patient- (ß = -4.85; 95% CI: -7.72, -1.99) post-engraftment in age-adjusted linear regression models. Mobility characteristics demonstrated immediate declines early pre-engraftment with stabilization by late pre-engraftment. CONCLUSION: Patients with hematological cancer experiencing gait limitations pretransplant are likely to have worse perceived function post-engraftment. Mobility declines in early phases post-transplant and may not fully recover, indicating an opportunity for timely rehabilitation referrals. Wearable inertial sensors can be used to identify early mobility problems and patients who may be at risk for future functional decline who may be candidates for early physical rehabilitation.

Informal Family Care Partner Well-Being Is Diminished in End-Stage Liver Disease.

BACKGROUND: Chronic liver disease is a significant global neglected public health problem. End-stage liver disease is associated with substantial symptom complexity, disability, and care needs that require assistance from informal family care partners. Research on these care partners' caregiver burden or strain, symptoms, and quality of life is sparse and has not focused on these variables as co-occurring or in the context of the quality of the relationship care partners have with the patients. OBJECTIVES: The purpose of this study was to provide a collective presentation of patterns and determinants of well-being as measured by caregiver strain, depression, sleep, and quality of life in a cohort of informal family care partners for adult outpatients with end-stage liver disease. METHODS: Care partners (aged >18 years) were recruited from two liver clinics within two tertiary healthcare systems and invited to complete a cross-sectional survey. They completed the Multidimensional Caregiver Strain Index, Patient Health Questionnaire, Pittsburgh Sleep Quality Index, Short Form Health Survey, and Mutuality Scale. Descriptive statistics and latent class mixture modeling were used to analyze these data. RESULTS: The sample was predominantly female and White. The well-being of care partners was diminished. Three distinct classes of well-being were identified: mildly diminished (53.2%), moderately diminished (39.0%), and severely diminished (7.8%). Those at a greater risk of worse well-being were younger and spouses and had poorer relationship quality with the patients. DISCUSSION: To improve the well-being of care partners in moderately and severely diminished classes, assessing and addressing caregiver strain and co-occurring symptoms is essential. Addressing the strain and symptoms has the potential to maintain or optimize care partners' ability to provide care to patients. Future researchers should include longitudinal and dyadic studies to examine how patients' disease progression and symptoms may affect family care partners' well-being and vice versa.

Assessing the Readiness of Rural Public Librarians to Implement Public Health Programs.

Although health promotion is not the primary function of public libraries, it is well documented that many libraries engage in health promotion activities, even when resources are constrained. Less understood is the readiness of the public library workforce, particularly in rural communities, to implement evidence-based health promotion programs. This study uses a modified version of the Competency Assessment for Tier 2 Public Health Professionals to assess the readiness of a small sample (n = 21) of Oregon rural library managers to implement evidence-based health initiatives. Results show that outside of communication skills, most rural library workers do not consider themselves to have proficiency in core health promotion competencies. Although some slight differences were found among librarians based on socio-demographic factors, those differences were not statistically significant. Implications include the need for strengthened support to build the capacity for rural public library workers who are interested in delivering evidence-based health promotion programs.

Characterizing public perceptions of social and cultural impacts in policy decisions.

Social scientists and community advocates have expressed concerns that many social and cultural impacts important to citizens are given insufficient weight by decision makers in public policy decision-making. In two large cross-sectional surveys, we examined public perceptions of a range of social, cultural, health, economic, and environmental impacts. Findings suggest that valued impacts are perceived through an initial lens that highlights both tangibility (how difficult it is to understand, observe, and make changes to an impact) and scope (how broadly an impact applies). Valued impacts thought to be less tangible and narrower in scope were perceived to have less support by both decision makers and the public. Nearly every valued impact was perceived to have more support from the public than from decision makers, with the exception of three economic considerations (revenues, profits, and costs). The results also demonstrate that many valued impacts do not fit neatly into the single-category distinctions typically used as part of impact assessments and cost-benefit analyses. We provide recommendations for practitioners and suggest ways that these results can foster improvements to the quality and defensibility of risk and impact assessments.

How people decide who is correct when groups of scientists disagree.

Uncertainty that arises from disputes among scientists seems to foster public skepticism or noncompliance. Communication of potential cues to the relative performance of contending scientists might affect judgments of which position is likely more valid. We used actual scientific disputes-the nature of dark matter, sea level rise under climate change, and benefits and risks of marijuana-to assess Americans' responses (n = 3150). Seven cues-replication, information quality, the majority position, degree source, experience, reference group support, and employer-were presented three cues at a time in a planned-missingness design. The most influential cues were majority vote, replication, information quality, and experience. Several potential moderators-topical engagement, prior attitudes, knowledge of science, and attitudes toward science-lacked even small effects on choice, but cues had the strongest effects for dark matter and weakest effects for marijuana, and general mistrust of scientists moderately attenuated top cues' effects. Risk communicators can take these influential cues into account in understanding how laypeople respond to scientific disputes, and improving communication about such disputes.

Association Between Adverse Childhood Experiences and Sleep Duration in US Children: Analysis of 2020-2021 National Survey of Children's Health.

BACKGROUND: Adverse childhood experiences (ACEs) and suboptimal sleep both negatively associate with cardiovascular health. Although an association between ACEs and suboptimal sleep in youth has been reported, there has been no investigation for differential effects among ACE subdomains. OBJECTIVE: We examined associations between total and subdomain ACEs and sleep duration, and age as a moderator. METHODS: Using the 2020-2021 National Survey of Children's Health and the American Heart Association Life's Essential 8 scoring algorithm, we created 3 sleep subgroups: (1) optimal, (2) suboptimal (≥1 to <2 hours below or ≥1 hour above optimal), and (3) very suboptimal (≥2 hours below optimal). We assessed association between ACEs (total and subdomains) and sleep duration using multinomial logistic regression, controlling for sex, age, race/ethnicity, caregiver's education, household income, habitual bedtime, and physical activity. We tested the interactions between ACEs and child's age. RESULTS: In children aged 6 to 17 years (N = 58 964), mean sleep duration score was 77.2 (95% confidence interval, 76.6-77.9). The mean number of ACEs was 0.89 (95% confidence interval, 0.87-0.91). Adjusting for covariates, each additional ACE increased the likelihood of falling into the suboptimal subgroup by 8% and the very suboptimal subgroup by 26%. There was an association between each subdomain of ACE and suboptimal sleep duration, with no significant interaction with age. CONCLUSIONS: Our findings show a dose-response relationship between ACEs and suboptimal sleep duration-a new cardiovascular health indicator in Life's Essential 8. Healthcare providers should screen for ACEs and suboptimal sleep in children to reduce future cardiovascular disease risk.

Identifying trajectories and predictors of chemotherapy-induced peripheral neuropathy symptoms, physical functioning, and falls across treatment and recovery in adults treated with neurotoxic chemotherapy: the PATTERN observational study protocol (NCT05790538).

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating and dose-limiting side effect of systemic cancer therapy. In many cancer survivors, CIPN persists after treatment ends and is associated with functional impairments, abnormal gait patterns, falls, and diminished quality of life. However, little is known regarding which patients are most likely to develop CIPN symptoms that impair mobility and increase fall risk, when this risk develops, or the optimal timing of early intervention efforts to mitigate the impact of CIPN on functioning and fall risk. This study will address these knowledge gaps by (1) characterizing trajectories of symptoms, functioning, and falls before, during, and after treatment in adults prescribed neurotoxic chemotherapy for cancer; and (2) determining the simplest set of predictors for identifying individuals at risk for CIPN-related functional decline and falls. METHODS: We will enroll 200 participants into a prospective, observational study before initiating chemotherapy and up to 1 year after completing chemotherapy. Eligible participants are aged 40-85 years, diagnosed with stage I-III cancer, and scheduled to receive neurotoxic chemotherapy. We perform objective assessments of vibratory and touch sensation (biothesiometry, tuning fork, monofilament tests), standing and dynamic balance (quiet stance, Timed-Up-and-Go tests), and upper and lower extremity strength (handgrip dynamometry, 5-time repeated chair stand test) in the clinic at baseline, every 4-6 weeks during chemotherapy, and quarterly for 1 year post-chemotherapy. Participants wear devices that passively and continuously measure daily gait quality and physical activity for 1 week after each objective assessment and self-report symptoms (CIPN, insomnia, fatigue, dizziness, pain, cognition, anxiety, and depressive symptoms) and falls via weekly electronic surveys. We will use structural equation modeling, including growth mixture modeling, to examine patterns in trajectories of changes in symptoms, functioning, and falls associated with neurotoxic chemotherapy and then search for distinct risk profiles for CIPN. DISCUSSION: Identifying simple, early predictors of functional decline and fall risk in adults with cancer receiving neurotoxic chemotherapy will help identify individuals who would benefit from early and targeted interventions to prevent CIPN-related falls and disability. TRIAL REGISTRATION: This study was retrospectively registered with ClinicalTrials.gov (NCT05790538) on 3/30/2023.

Rural libraries implementing walking groups or walking groups plus civic engagement for walkability in rural communities: a comparative effectiveness trial study protocol.

BACKGROUND: Rural residents generally lack adequate physical activity to benefit health and reduce disparities in chronic diseases, such as cardiovascular disease and certain cancers. The Socioecological Model describes physical activity as involving a dynamic and reciprocal interaction between individual, social, and community factors. Community group-based walking programs and civic engagement interventions aimed at enhancing physical activity have been successful in rural communities but have not targeted all three socioecological levels. Public libraries can act as innovative public health partners in rural communities. However, challenges remain because rural libraries often lack the capacity to implement evidence-based health promotion programming. The goals of this study are (1) build the capacity for rural libraries to implement evidence-based health promotion programs, (2) compare changes in physical activity between a group-based walking program and a combined group-based walking and civic engagement program with rural residents, and (3) conduct an implementation evaluation. METHODS: We will conduct a comparative effectiveness study of a group-based walking (standard approach) versus a group-based walking plus civic engagement program (combined approach) aimed at enhancing walkability to increase physical activity among rural adults. Key mediators between the program effects and change in outcomes will also be identified. Finally, we will evaluate program implementation, conduct a cost effectiveness evaluation, and use a positive deviance analysis to understand experiences of high and low changers on key outcomes. Twenty towns will be matched and randomized to one of the two conditions and our aim is to enroll a total of 350-400 rural residents (15-20 per town). Study outcomes will be assessed at baseline, and 6, 12, and 24 months. DISCUSSION: This study will build the capacity of rural libraries to implement evidence-based walking programs as well as other health promotion programs in their communities. The study results will answer questions regarding the relative effectiveness and cost effectiveness of two multilevel physical activity interventions targeting rural communities. We will learn what works and how these multilevel interventions can be implemented in rural populations. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05677906.

Are Physical and Depressive Symptoms Different Between Women and Men With Heart Failure?: An Exploration Using Two Analytic Techniques.

BACKGROUND: Adults with heart failure (HF) experience a constellation of symptoms; however, understanding of gender differences in HF symptoms remain elusive. The aim of this study was to determine whether there are gender differences in physical and depressive symptoms and symptom patterns in HF using 2 different analytic techniques. METHODS: We performed a secondary analysis of combined data from 6 studies of adults with HF. Physical symptoms were measured with the HF Somatic Perception Scale, and depressive symptoms were measured with the Patient Health Questionnaire-9. First, we performed propensity matching with the nearest neighbor to examine the average treatment effect for HF Somatic Perception Scale and Patient Health Questionnaire-9 in the matched sample of women and men. Next, we used the entire data set in a latent class mixture model to determine patterns of symptoms. Finally, we calculated predictors of class membership with multinomial logistic regression. RESULTS: The sample (n = 524, 86.5% systolic HF) was 37% women with a mean age of 58.3 ± 13.9 years and mean number of years with HF of 6.9 ± 6.9. Three hundred sixty-six participants were matched on propensity scores; there were no significant gender differences in symptom scores between matched women (n = 183) and men (n = 183). Among all 524 participants, 4 distinct latent classes of symptom patterns indicate that many patients with HF are fatigued, some have more depressive symptoms, and others have significantly more edema or cough. Gender did not predict membership to any symptom pattern. CONCLUSIONS: There were significant gender differences in sociodemographics, health behaviors, and clinical characteristics, but not HF symptoms or symptom patterns, using either analytic technique.

Symptom Classes in Decompensated Liver Disease.

BACKGROUND & AIMS: Patients with decompensated liver disease have been categorized by disease severity. This analysis sought to classify patients with end-stage liver disease based on symptoms rather than disease state and to identify distinct severity classes of physical and psychological symptoms. METHODS: Patients with a model for end-stage liver disease-sodium score of 15 or higher were recruited from liver clinics in 2 health care organizations. They completed the Condensed Memorial Symptom Assessment Scale, Revised Ways of Coping Checklist, Patient Health Questionnaire, Life Orientation Test-Revised, and the Short-Form Health Survey. Cross-sectional data were analyzed using latent class mixture modeling. RESULTS: The sample (N = 191; age, 56.6 ± 11.1 y; 33.5% ETOH; 28.3% nonalcoholic fatty liver disease; 13.1% autoimmune/primary biliary cholangitis/primary sclerosing cholangitis) was predominantly male (64.2%), Child-Turcotte-Pugh class C (49.5%), with an average model for end-stage liver disease-sodium score of 18.7 ± 4.9. Three distinct classes of symptoms were identified, as follows: mild (26.7%), moderate (41.4%), or severe (31.9%) symptoms. Symptom classes were independent of disease severity and demographic characteristics, except age. All Condensed Memorial Symptom Assessment Scale symptoms and Patient Health Questionnaire scores were significantly different across the 3 classes (P < .05). The symptom classes also differed significantly in physical and mental quality of life, optimism, and avoidance coping behaviors (all P < .001). CONCLUSIONS: Patient-reported symptom severity occurred independent of disease severity, contrary to common assumptions. Focusing on the moderate and severe symptom classes as well as patient history of end-stage liver disease complications may enhance providers' ability to improve symptom management for this population.

Symptom Frequency and Distress Underestimated in Decompensated Cirrhosis.

BACKGROUND: Studies assessing multiple symptoms and the distress of these symptoms in decompensated cirrhosis are lacking. AIMS: The aims of this study were to assess symptom prevalence and distress among patients with decompensated cirrhosis and to describe medical management of the most prevalent symptoms. METHODS: Patients were recruited from hepatology clinics within two health-care systems. Eligibility criteria included a model for end-stage liver disease (MELD-Na) score ≥15. Patients completed the Condensed Memorial Symptom Assessment Scale and Patient Health Questionnaire. Comparative statistics were used to analyze the cross-sectional survey data. RESULTS: Of the sample (n = 146), most patients were Child-Turcotte-Pugh (CTP) class B (49.7%) and C (46.2%). Mean age was 56.5 years, 65.1% were male, and 88.4% were white. Average MELD-Na score was 19.1 ± 4.5. The most prevalent symptoms were lack of energy and feeling drowsy while the most distressing were lack of energy and difficulty sleeping. Only 24 patients (16.4%) were treated for their difficulty sleeping with sleep medication. Importantly, those prescribed sleep medications had similar distress (3.9 ± 1.2 vs. 3.5 ± 1.2, p = 0.229) compared with patients not prescribed sleep medications. Opioids were prescribed to 57 (39.0%) patients; antidepressants to 34 (23.3%). Forty patients (27.4%) who reported moderate or greater depression were not prescribed an antidepressant. CONCLUSIONS: The study highlights the multiple symptoms and distress experienced by patients with decompensated cirrhosis, and the need for improved medical management by health-care providers through enhanced awareness and attention to these complex symptoms. Future research should focus on improvements in symptom management.

Trajectories and biopsychosocial predictors of daily acute pain in adolescents receiving treatment for pain: a daily diary study.

Research regarding daily acute pain and its correlates has primarily been conducted with adolescents who have had major surgery or musculoskeletal pain, restraining efforts towards adapting interventions for adolescents with other sources of acute pain. We explored the trajectories and correlates of pain intensity. Adolescents with an opioid prescription to treat acute pain (N = 157) completed demographic questions, and the PROMIS pediatric depression and anxiety subscales. A 10-day daily diary assessed pain intensity, pain interference, sleep quality, and opioid use. Three trajectories of pain intensity emerged: (1) slow decreases in pain, (2) rapid decreases in pain, and (3) stable or slight increases in pain. Teens with stable pain demonstrated the greatest anxiety levels. Higher sleep quality predicted lower next day pain intensity and pain interference, when controlling for opioid use. Future research should employ intensive longitudinal methodology to further guide intervention development and prevent the transition to chronic pain.

Dissertation Topics in Nursing.

BACKGROUND: Few quantitative studies have documented the types of research topics most commonly employed by nursing PhD students and whether they differ by program delivery (in-person vs. online/hybrid programs). OBJECTIVES: We examined a large set of publicly available PhD dissertation abstracts to (a) describe the relative prevalence of different research topics and methods and (b) test whether the primary topics and methods used differed between online or hybrid and in-person PhD programs. A secondary goal was to introduce the reader to modern text-mining approaches to generate insights from a document corpus. METHODS: Our database consisted of 2,027 dissertation abstracts published between 2015 and 2019. We used a structural topic modeling text-mining approach to explore PhD students' research topics and methods in United States-based doctoral nursing programs. RESULTS: We identified 24 different research topics representing a wide range of research activities. Most of the research topics identified did not differ in prevalence between online/hybrid and in-person programs. However, online/hybrid programs were more likely to engage students in research focused on nursing education, professional development, work environment, simulation, and qualitative analysis. Pediatrics, sleep science, older adults and aging, and chronic disease management were more prevalent topics in in-person-only programs. DISCUSSION: The range of topics identified highlights the breadth of research nursing PhD students' conduct. Both in-person and online/hybrid programs offer a range of research opportunities, although we did observe some differences in topic prevalence. These differences could be due to the nature of some types of research (e.g., research that requires an in-person presence) or differences in research intensity between programs (e.g., amount of grant funding or proximity to a medical center). Future research should explore why research topic prevalence may vary by program delivery. We hope that this text-mining application serves as an illustrative example for researchers considering how to draw inferences from large sets of text documents. We are particularly interested in seeing future work that might combine traditional qualitative approaches and large-scale text mining to leverage the advantages of each.

Chronic Pain Clinical and Prescriptive Practices in the Cannabis Era.

BACKGROUND: To explore how health care providers in the United States are adapting clinical recommendations and prescriptive practices in response to patient use of medical cannabis (MC) for chronic pain symptoms. DESIGN: Literature searches queried MeSH/Subject terms "chronic pain," "clinician," "cannabis," and Boolean text words "practice" and "analgesics" in EBSCOHost, EMBASE, PubMed, and Scopus, published 2010-2021 in the United States. Twenty-one primary, peer-reviewed studies met criteria. METHODS: Studies are synthesized under major headings: recommending MC for chronic pain; MC and prescription opioids; and harm reduction of MC. RESULTS: MC is increasingly utilized by patients for chronic pain symptoms. Clinical recommendations for or against MC are influenced by scopes of practice, state or federal laws, institutional policies, education, potential patient harm (or indirect harm of others), and perceived confidence. Epidemiologic and cohort studies show downward trajectories of opioid prescribing and consumption in states with legal cannabis. However, clinicians' recommendations and prescription practices are nonuniform. Impacts of cannabis laws are clear between nongovernmental and governmental institutions. Strategies addressing MC and opioid use include frequent visits, and, to reduce harm, suggesting alternative therapies and treating substance use disorders. CONCLUSIONS: MC use for chronic pain is increasing with cannabis legalization. Provider practices are heterogenous, demonstrating a balance of treating chronic pain using available evidence, while being aware of potential harms associated with MC and opioids.

Physical and Mental Quality of Life in Patients With End-Stage Liver Disease and Their Informal Caregivers.

BACKGROUND & AIMS: Management of end-stage liver disease (ESLD) has implications for not only patients' quality of life (QOL), but also their caregivers'. We aimed to identify characteristics of patients with ESLD and their caregivers that are associated with QOL. METHODS: We obtained cross-sectional baseline data from patients and their caregivers (132 dyads; 62% were married or partners), recruited from outpatient hepatology clinics within 2 healthcare centers. Patients were included if their model for end-stage liver disease score was 15 or more; caregivers were identified by the patient as the primary informal caregiver. QOL was measured by the SF-36 and relationship quality using the mutuality scale. We measured uncertainty using the uncertainty in illness scales for patients and caregivers. Multilevel modeling was used to analyze the data. RESULTS: Refractory ascites was associated with worse physical QOL for patients (unstandardized beta [B], -9.19; standard error [SE], 2.28) and caregivers (B, -5.41; SE, 2.33); history of hepatic encephalopathy was associated with worse patient physical QOL (B, -3.86; SE, 1.65). High levels of uncertainty were associated with worse physical and mental QOL for both members of the dyads; relationship quality was significantly associated with patient mental QOL (B, 2.73; SE, 1.19). CONCLUSIONS: Clinicians and researchers should consider the effects of ESLD on caregivers as well as their patients to optimize the QOL for both.

Feasibility and potential benefits of partner-supported yoga on psychosocial and physical function among lung cancer patients.

OBJECTIVE: Patients with lung cancer experience significant declines in psychosocial and physical function during and after treatment that impact quality of life (QOL) and survival. Yoga is a potential strategy to mitigate functional decline among patients with lung cancer. METHODS: A single group 12-week pilot trial of low-moderate intensity yoga among patients with stage I-IV lung cancer and their partners (n = 46; 23 patient-partner dyads) during cancer treatment from two hospital systems. Feasibility, acceptability, descriptive statistics, and Cohen d effect sizes were calculated at 6 and 12-weeks for psychosocial and physical outcomes using validated questionnaires and assessments. RESULTS: At 6 and 12-weeks, retention was 65% and withdrawals were mainly due to disease progression. Among study completers (n = 26; 13 dyads) adherence was 80%. Comparing baseline to 12-week measurements, fatigue, depression symptoms, and sleep disturbance improved in 54% of participants for all three measures (Cohen's d = 0.40-0.53). QOL improved in 77% of participants (Cohen's d = 0.34). Upper and lower body flexibility, and lower body strength improved in 92%, 85% and 77% of participants, respectively (Cohen's d = 0.39-1.08). Six-minute walk test improved in 62% of participants an average of 32 meters (SD = 11.3; Cohen's d = 0.17). No serious adverse events were reported. CONCLUSIONS: Among patients with stage I-IV lung cancer including active treatment, a 12-week partner-supported yoga program is feasible, acceptable, and improved psychosocial and physical function. Low-intensity yoga may be a complimentary approach to reduce the effects of cancer treatment, however, more research is needed to determine the efficacy of partner-supported yoga to mitigate functional decline.

Communicating Scientific Uncertainty About the COVID-19 Pandemic: Online Experimental Study of an Uncertainty-Normalizing Strategy.

BACKGROUND: Communicating scientific uncertainty about public health threats such as COVID-19 is an ethically desirable task endorsed by expert guidelines on crisis communication. However, the communication of scientific uncertainty is challenging because of its potential to promote ambiguity aversion-a well-described syndrome of negative psychological responses consisting of heightened risk perceptions, emotional distress, and decision avoidance. Communication strategies that can inform the public about scientific uncertainty while mitigating ambiguity aversion are a critical unmet need. OBJECTIVE: This study aimed to evaluate whether an "uncertainty-normalizing" communication strategy-aimed at reinforcing the expected nature of scientific uncertainty about the COVID-19 pandemic-can reduce ambiguity aversion, and to compare its effectiveness to conventional public communication strategies aimed at promoting hope and prosocial values. METHODS: In an online factorial experiment conducted from May to June 2020, a national sample of 1497 US adults read one of five versions of an informational message describing the nature, transmission, prevention, and treatment of COVID-19; the versions varied in level of expressed scientific uncertainty and supplemental focus (ie, uncertainty-normalizing, hope-promoting, and prosocial). Participants then completed measures of cognitive, emotional, and behavioral manifestations of ambiguity aversion (ie, perceived likelihood of getting COVID-19, COVID-19 worry, and intentions for COVID-19 risk-reducing behaviors and vaccination). Analyses assessed (1) the extent to which communicating uncertainty produced ambiguity-averse psychological responses; (2) the comparative effectiveness of uncertainty-normalizing, hope-promoting, and prosocial communication strategies in reducing ambiguity-averse responses; and (3) potential moderators of the effects of alternative uncertainty communication strategies. RESULTS: The communication of scientific uncertainty about the COVID-19 pandemic increased perceived likelihood of getting COVID-19 and worry about COVID-19, consistent with ambiguity aversion. However, it did not affect intentions for risk-reducing behaviors or vaccination. The uncertainty-normalizing strategy reduced these aversive effects of communicating scientific uncertainty, resulting in levels of both perceived likelihood of getting COVID-19 and worry about COVID-19 that did not differ from the control message that did not communicate uncertainty. In contrast, the hope-promoting and prosocial strategies did not decrease ambiguity-averse responses to scientific uncertainty. Age and political affiliation, respectively, moderated the effects of uncertainty communication strategies on intentions for COVID-19 risk-reducing behaviors and worry about COVID-19. CONCLUSIONS: Communicating scientific uncertainty about the COVID-19 pandemic produces ambiguity-averse cognitive and emotional, but not behavioral, responses among the general public, and an uncertainty-normalizing communication strategy reduces these responses. Normalizing uncertainty may be an effective strategy for mitigating ambiguity aversion in crisis communication efforts. More research is needed to test uncertainty-normalizing communication strategies and to elucidate the factors that moderate their effectiveness.
