Clinician Perspectives on Palliative Care for People with Hepatocellular Carcinoma: Facilitators of and Barriers to Referral.

(1) Background: Little is known about facilitators of and barriers to palliative care referral for people with hepatocellular carcinoma (HCC). The objective of this study is to identify facilitators and barriers of palliative care referral described by HCC-treating clinicians. (2) Methods: Semi-structured interviews (n = 16) were conducted with HCC-treating clinicians at two centers, focusing on referral patterns, palliative care needs, and disease course. A code book was created, axial coding was used to code all interviews, and selective coding was used to identify facilitators and barriers of palliative care referral. (3) Results: Facilitators included helpfulness at times of transition; help with management of certain symptoms; provision of psychosocial support; and positive experiences with referral. Barriers included feasibility concerns; lack of information about palliative care and who is appropriate; lack of symptoms requiring outside referral; and concerns that palliative care conveys loss of hope. (4) Conclusions: Participants noted the helpfulness of palliative care at specific points in the disease trajectory and cited barriers related to feasibility, lack of need, lack of awareness, and loss of hope. The results show actionable issues that can be addressed in future research to leverage the benefits of and overcome the barriers to palliative care for people with HCC.

Targets and study design for symptom-focused trials aimed at patients with cirrhosis: An expert consensus.

BACKGROUND: Symptom-focused trials are critically needed for patients with cirrhosis. However, this work would benefit from standard processes and validated measures. METHODS: A writing group was formed among hepatologists, nurses, palliative care providers, pharmacists, and clinical trial experts focused on symptom management in patients with cirrhosis to define the key (1) components of trial design, (2) symptom targets, (3) measurement, and (4) outcomes for each target. From July 2022 to January 2023, panelists participated in an iterative process of developing and arriving at a consensus for each component. The goal was to provide consensus definitions that can be operationalized in future clinical trials, including for patients with cirrhosis. RESULTS: The panel reached a consensus on key reporting features for clinical trials, along with considerations for study design. Nine key symptom targets (muscle cramps, pruritus, pain, fatigue, sexual dysfunction, sleep disorders, depression and anxiety, nausea/vomiting, and dyspnea/breathlessness) were identified. The panel selected instruments that can be considered for clinical trials based on psychometric validation and previous experience. The panel identified ongoing needs, including instrument validation, safety data, evidence about non-pharmacologic interventions, and comparative effectiveness studies. CONCLUSION: This expert panel identified key design, reporting, and measurement elements to standardize processes and measures in future symptom-focused clinical trials in the context of cirrhosis.

Top Ten Tips Palliative Care Clinicians Should Know About End-Stage Liver Disease.

End-stage liver disease (ESLD) is an increasingly prevalent condition with high morbidity and mortality, especially for those ineligible for liver transplantation. Patients with ESLD, along with their family caregivers, have significant needs related to their quality of life, and there is increasing attention being paid to integration of palliative care (PC) principles into routine care throughout the disease spectrum. To provide upstream care for these patients and their family caregivers, it is essential for PC providers to understand their complex psychosocial and physical needs and to be aware of the unique challenges around medical decision making and end-of-life care for this patient population. This article, written by a team of liver and PC experts, shares 10 high-yield tips to help PC clinicians provide better care for patients with advanced liver disease.

Inpatient Specialty-Level Palliative Care Is Delivered Late in the Course of Hepatocellular Carcinoma and Associated With Lower Hazard of Hospital Readmission.

CONTEXT: Little is known about receipt of specialty-level palliative care by people with hepatocellular carcinoma (HCC) or its impact on health care utilization. OBJECTIVES: Identify patient characteristics associated with receipt of specialty-level palliative care among hospitalized HCC patients and measure association with time to readmission. METHODS: We used logistic regression to examine relationships between receipt of inpatient palliative care consultation by HCC patients at an academic center (N = 811; 2012-2016) and clinical and demographic covariates at index hospitalization. We used a survival analysis model accounting for competing risk of mortality to compare time to readmission among individuals who did or did not receive palliative care during the admission and performed a sensitivity analysis using kernel weights to account for selection bias. RESULTS: Overall, 16% received inpatient palliative care consults. Those who received consults had worse laboratory values than those who did not. In a multivariable model, higher Model for End-Stage Liver Disease Sodium, receipt of sorafenib, and higher pain scores were significantly associated with increased odds of palliative care, whereas liver transplantation and admission to a surgical service were associated with lower odds. For time to readmission (2076 hospitalizations for 811 individuals with 175 palliative care visits), the subhazard ratio for readmission for patients who received consults was 0.26 (95% CI = 0.18-0.38) and 0.35 (95% CI = 0.24-0.52) with a kernel-weighted sample. CONCLUSION: Inpatient palliative care consultation was received by individuals with more advanced disease and associated with lower readmission hazard. These findings support further research and the development of HCC-specific programs that increase access to specialty-level palliative care.

Palliative Care for People With Hepatocellular Carcinoma, and Specific Benefits for Older Adults.

PURPOSE: Hepatocellular carcinoma (HCC), the most common type of primary liver cancer, has a rapidly rising prevalence in the United States and a very poor overall rate of survival. This epidemic is driven by the cohort of aging Baby Boomers with hepatitis C viral infection and the increasing prevalence of cirrhosis as a result of nonalcoholic steatohepatitis. Because curative options are limited, the disease course creates, in patients and their families, distressing uncertainty around prognosis and treatment decisions. Older adults are disproportionately affected by HCC and have more comorbidities, adding to the complexity of the disease. This population would benefit from increased access to palliative care services, which can potentially complement the treatments throughout the disease trajectory. The purpose of this review was to use existing evidence to propose a new model of palliative care integration in patients with HCC. Thus, we focus on the HCC stage and the treatment algorithm, the ways that palliative care can offer support in this population at each stage, as well as elements that can enhance patient and family support throughout the entire disease trajectory, with an emphasis on the care of older adults with HCC. METHODS: This is a narrative review in which we identify evidence-based ways that palliative care can help younger and older adults with HCC and their families, at each stage of HCC and throughout the disease trajectory. FINDINGS: We propose ways to integrate HCC and palliative care based on the existing evidence in both fields. Palliative care offers support in symptom management, advanced care planning, and decision making in ways that are specific to each stage of HCC. We also discuss the evidence that illustrates the palliative care needs of patients with HCC that span the entire course of illness, including coping with the stigmatization of liver disease, addressing informational needs at different stages, and discussing quality of life longitudinally. IMPLICATIONS: Integrating palliative care into the treatment of patients with HCC has the potential to improve outcomes, although more research is needed to build this evidence base.

Exogenous calreticulin improves diabetic wound healing.

A serious consequence of diabetes mellitus is impaired wound healing, which largely resists treatment. We previously reported that topical application of calreticulin (CRT), an endoplasmic reticulum chaperone protein, markedly enhanced the rate and quality of wound healing in an experimental porcine model of cutaneous repair. Consistent with these in vivo effects, in vitro CRT induced the migration and proliferation of normal human cells critical to the wound healing process. These functions are particularly deficient in poor healing diabetic wounds. Using a genetically engineered diabetic mouse (db/db) in a full-thickness excisional wound healing model, we now show that topical application of CRT induces a statistically significant decrease in the time to complete wound closure compared with untreated wounds by 5.6 days (17.6 vs. 23.2). Quantitative analysis of the wounds shows that CRT increases the rate of reepithelialization at days 7 and 10 and increases the amount of granulation tissue at day 7 persisting to day 14. Furthermore, CRT treatment induces the regrowth of pigmented hair follicles observed on day 28. In vitro, fibroblasts isolated from diabetic compared with wild-type mouse skin and human fibroblasts cultured under hyperglycemic compared with normal glucose conditions proliferate and strongly migrate in response to CRT compared with untreated controls. The in vitro effects of CRT on these functions are consistent with CRT's potent effects on wound healing in the diabetic mouse. These studies implicate CRT as a potential powerful topical therapeutic agent for the treatment of diabetic and other chronic wounds.

Calreticulin enhances porcine wound repair by diverse biological effects.

Extracellular functions of the endoplasmic reticulum chaperone protein calreticulin (CRT) are emerging. Here we show novel roles for exogenous CRT in both cutaneous wound healing and diverse processes associated with repair. Compared with platelet-derived growth factor-BB-treated controls, topical application of CRT to porcine excisional wounds enhanced the rate of wound re-epithelialization. In both normal and steroid-impaired pigs, CRT increased granulation tissue formation. Immunohistochemical analyses of the wounds 5 and 10 days after injury revealed marked up-regulation of transforming growth factor-beta3 (a key regulator of wound healing), a threefold increase in macrophage influx, and an increase in the cellular proliferation of basal keratinocytes of the new epidermis and of cells of the neodermis. In vitro studies confirmed that CRT induced a greater than twofold increase in the cellular proliferation of primary human keratinocytes, fibroblasts, and microvascular endothelial cells (with 100 pg/ml, 100 ng/ml, and 1.0 pg/ml, respectively). Moreover, using a scratch plate assay, CRT maximally induced the cellular migration of keratinocytes and fibroblasts (with 10 pg/ml and 1 ng/ml, respectively). In addition, CRT induced concentration-dependent migration of keratinocytes, fibroblasts macrophages, and monocytes in chamber assays. These in vitro bioactivities provide mechanistic support for the positive biological effects of CRT observed on both the epidermis and dermis of wounds in vivo, underscoring a significant role for CRT in the repair of cutaneous wounds.

Phototriggered delivery of hydrophobic carbonic anhydrase inhibitors.

We have developed a versatile tool for the delivery of inhibitors of carbonic anhydrase II, which allows modification of a hydrophobic drug with either a water-solubilizing, photolabile cage or a hydrophobic, photolabile cage. The former mask is useful for direct delivery of hydrophobic molecules in an aqueous prodrug form. The latter may find application if delivery from a surface is desirable. In our system, where the target enzyme is found in the eye, both approaches may be useful for the delivery of hydrophobic drugs having subnanomolar dissociation constants from the enzyme.
