Outcomes of a 3-Year Quality Improvement Study to Improve Advance Care Planning in Patients With Decompensated Cirrhosis.

INTRODUCTION: To report outcomes of a 3-year quality improvement pilot study to improve advance directive (AD) completion. METHODS: The pilot consisted of champions, education, electronic health record templates, and workflow changes. We assessed changes, predictors, and effects of AD completion. RESULTS: The pilot led to greater (8.3%-36%) and earlier AD completion, particularly among those divorced, with alcohol-associated liver disease, and with higher Model of End-Stage Liver Disease-Sodium score. Decedents whose AD specified nonaggressive goals experienced lower hospital lengths of stay. DISCUSSION: Advance care planning initiatives are feasible and may reduce health care utilization among decedents requesting less aggressive care.

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.

Feasibility of a Palliative Care Intervention within Routine Care of Hepatocellular Carcinoma: A Pilot Randomized Controlled Trial.

Background: Patients with hepatocellular cancer (HCC) are at risk for poor quality of life (QoL) and high symptom burden, coupled with limited treatment options. Palliative care (PC) can play an important role in reducing the suffering of this population, but remains underutilized. Aim: To demonstrate feasibility of an outpatient PC intervention within HCC care. Methods: This is a pilot randomized controlled trial conducted at an academic center. All stages of HCC patients (except Barcelona Clinic Liver Cancer stage D) with a scheduled hepatology appointment were eligible. Patients were randomized to receive PC intervention or usual care (control arm). In the PC arm, patients received PC from a PC provider at enrollment and at three months from the baseline visit, in addition to continued standard of care. Control arm received only standard care. All patients completed FACT-Hep (Functional Assessment of Cancer Therapy-Hepatobiliary Cancer) and modified Edmonton Symptom Assessment Scale at baseline and at three-month visit. Descriptive statistics were utilized to summarize questionnaires, and change in QoL and symptoms from baseline to three months were compared between the two study groups. Results: Of the 109 approached, 57 patients (52.3%) consented to enroll, and 52 (91%) completed the study. QoL and symptom burden assessments demonstrated impaired QoL and high symptom burden in both arms of the study. At least 50% of enrolled patients in each arm had some degree of fatigue, pain, sleep disturbance, and appetite loss, at baseline. Post-intervention, symptom burden and QoL improved in the intervention arm and remained same or worsened in the control group. All FACT-Hep scores decreased numerically among controls and increased numerically among patients in the PC intervention group. Conclusion: Outpatient PC intervention within routine HCC care is feasible, and can potentially improve QoL and symptoms.

Opioid Prescription Is Associated With Increased Survival in Older Adult Patients With Pancreatic Cancer in the United States: A Propensity Score Analysis.

PURPOSE: Few studies have assessed the interaction between pain treatment and mortality in pancreatic cancer. The aim of this study was to investigate the association between receipt of opioid prescriptions and survival in adults with pancreatic cancer. METHODS: The SEER-Medicare linked database was used to identify patients diagnosed with late-stage pancreatic cancer between 2007 and 2015. Kaplan-Meier models were used to assess the association between opioid prescriptions in the year after cancer diagnosis and survival. Cox proportional hazard models were used to determine the association between opioid receipt and survival, adjusting for propensity score and other relevant confounders including cancer-directed therapies and palliative care referral. RESULTS: A total of 5,770 older adults with pancreatic cancer were identified; 1,678 (29.1%) were prescribed opioids for at least 60 days. Median survival was increased in those with opioid prescriptions (6.0 months) compared with those without (4.0 months, P < .0001). After adjustment for confounders, opioid prescriptions were still associated with improved survival (hazard ratio 0.80; 95% CI, 0.75 to 0.86). On multivariable analysis, opioid prescriptions were associated with older age, female sex, residing in nonmetro areas, and treatment with celiac plexus neurolysis, chemotherapy, and radiation. CONCLUSION: Receipt of opioid prescriptions is associated with longer survival in patients with pancreatic cancer. This may be due to the impact of cancer-related pain, although further studies are needed to better understand the interaction between pain management, cancer-directed therapies, and systemic factors, such as palliative care, availability of opioids, and clinical practice culture.

Developing Priorities for Palliative Care Research in Advanced Liver Disease: A Multidisciplinary Approach.

Individuals with advanced liver disease (AdvLD), such as decompensated cirrhosis (DC) and hepatocellular carcinoma (HCC), have significant palliative needs. However, little research is available to guide health care providers on how to improve key domains related to palliative care (PC). We sought to identify priority areas for future research in PC by performing a comprehensive literature review and conducting iterative expert panel discussions. We conducted a literature review using search terms related to AdvLD and key PC domains. Individual reviews of these domains were performed, followed by iterative discussions by a panel consisting of experts from multiple disciplines, including hepatology, specialty PC, and nursing. Based on these discussions, priority areas for research were identified. We identified critical gaps in the available research related to PC and AdvLD. We developed and shared five key priority questions incorporating domains related to PC. Conclusion: Future research endeavors focused on improving PC in AdvLD should consider addressing the five key priorities areas identified from literature reviews and expert panel discussions.

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.

Primary Care-Based Hepatitis C Treatment Outcomes With First-Generation Direct-Acting Agents.

OBJECTIVES: Vulnerable, urban populations with a history of substance use disorders have a high prevalence of hepatitis C virus (HCV). Primary care-based treatment has been proposed to improve access to care. In this study, we present outcomes from our urban, primary care-based HCV treatment program in patients treated with telaprevir or boceprevir in combination with pegylated-interferon and ribavirin ("triple therapy"). METHODS: We collected data from 126 consecutive patients with genotype 1 HCV monoinfection seen in our treatment program (2011-2013). Among the 40 who initiated treatment, we analyzed factors associated with achieving a sustained viral response (SVR). RESULTS: During the study period, 40 patients initiated triple therapy (32%), 80% with recent or past substance use disorders. Patients initiating treatment were younger than untreated patients (P = 0.002), but otherwise did not differ demographically, or in the severity of their liver fibrosis (P > 0.05). An SVR was achieved in 18 patients (45%) and was less likely in patients with recent or past substance use disorders or psychiatric illness (both P < 0.01). CONCLUSIONS: Nearly one third of patients initiated triple therapy with SVR rates comparable to other HCV treatment settings, despite a significant burden of mental illness and substance dependence. Our experience demonstrates that a primary care-based practice can successfully deliver HCV care to a vulnerable population. Additional interventions may be needed to improve outcomes in patients with recent or past substance use disorders or psychiatric illness.

Reduced hepatic stellate cell expression of Kruppel-like factor 6 tumor suppressor isoforms amplifies fibrosis during acute and chronic rodent liver injury.

UNLABELLED: Kruppel-like factor 6 (KLF6), a zinc finger transcription factor and tumor suppressor, is induced as an immediate-early gene during hepatic stellate cell (HSC) activation. The paradoxical induction of a tumor suppressor in HSCs during proliferation led us to explore the biology of wildtype KLF6 (KLF6(WT) ) and its antagonistic, alternatively spliced isoform KLF6(SV1) in cultured HSCs and animal models. The animal models generated include a global heterozygous KLF6 mouse (Klf6+/-), and transgenic mice expressing either hKLF6(WT) or hKLF6(SV1) under the control of the Collagen α2 (I) promoter to drive HSC-specific gene expression following injury. The rat Klf6 transcript has multiple splice forms that are homologous to those of the human KLF6 gene. Following a transient increase, all rat Klf6 isoforms decreased in response to acute carbon tetrachloride (CCl(4)) liver injury and culture-induced activation. After acute CCl(4), Klf6+/- mice developed significantly increased fibrosis and enhanced fibrogenic messenger RNA (mRNA) and protein expression. In contrast, HSC-specific transgenic mice overexpressing KLF6(WT) or KLF6(SV1) developed significantly diminished fibrosis with reduced expression of fibrogenic genes. Chromatin IP and quantitative reverse-transcription polymerase chain reaction in mouse HSCs overexpressing KLF6(WT) demonstrated KLF6(WT) binding to GC boxes in promoters of Colα1 (I), Colα2 (I), and beta-platelet-derived growth factor receptor (ß-Pdgfr) with reduced gene expression, consistent with transcriptional repression by KLF6. Stellate cells overexpressing either KLF6(WT) or KLF6(SV1) were more susceptible to apoptotic stress based on poly (ADP-ribose) polymerase (PARP) cleavage. CONCLUSION: KLF6 reduces fibrogenic activity of HSCs by way of two distinct mechanisms, direct transcriptional repression of target fibrogenic genes and increased apoptosis of activated HSCs. These results suggest that following its initial induction, sustained down-regulation of KLF6 in liver injury may allow de-repression of fibrogenic genes and decreased stellate cell clearance by inhibiting apoptosis.

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.

A basic/hydrophobic cleft of the T4 activator MotA interacts with the C-terminus of E.coli sigma70 to activate middle gene transcription.

Transcriptional activation often employs a direct interaction between an activator and RNA polymerase. For activation of its middle genes, bacteriophage T4 appropriates Escherichia coli RNA polymerase through the action of two phage-encoded proteins, MotA and AsiA. Alone, AsiA inhibits transcription from a large class of host promoters by structurally remodelling region 4 of sigma(70), the primary specificity subunit of E. coli RNA polymerase. MotA interacts both with sigma(70) region 4 and with a DNA element present in T4 middle promoters. AsiA-induced remodelling is proposed to make the far C-terminus of sigma(70) region 4 accessible for MotA binding. Here, NMR chemical shift analysis indicates that MotA uses a 'basic/hydrophobic' cleft to interact with the C-terminus of AsiA-remodelled sigma(70), but MotA does not interact with AsiA itself. Mutations within this cleft, at residues K3, K28 and Q76, both impair the interaction of MotA with sigma(70) region 4 and MotA-dependent activation. Furthermore, mutations at these residues greatly decrease phage viability. Most previously described activators that target sigma(70) directly use acidic residues to engage a basic surface of region 4. Our work supports accumulated evidence indicating that 'sigma appropriation' by MotA and AsiA uses a fundamentally different mechanism to activate transcription.

A TAF4-homology domain from the corepressor ETO is a docking platform for positive and negative regulators of transcription.

The eight twenty-one protein, ETO, is implicated in 12%-15% of acute human leukemias as part of a gene fusion with RUNX1 (also called AML1). Of the four ETO domains related to Drosophila melanogaster Nervy, only two are required to induce spontaneous myeloid leukemia upon transplantation into the mouse. One of these domains is related in sequence to TAF4, a component of TFIID. The structure of this domain, ETO-TAFH, is similar to yeast Rpb4 and to Escherichia coli sigma(70); it is the first TAF-related protein with structural similarity to the multisubunit RNA polymerases. Overlapping surfaces of ETO-TAFH interact with an autonomous repression domain of the nuclear receptor corepressor N-CoR and with a conserved activation domain from the E-box family of transcription factors. Thus, ETO-TAFH acts as a structural platform that can interchange negative and positive coregulatory proteins to control transcription.

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.
