Piloting HealthScore: Feasibility and acceptability of a clinically integrated health coaching program for people living with cancer.

BACKGROUND: Cancer supportive care interventions often have limited generalizability, goal misalignment, and high costs. We developed and piloted a health coaching intervention, UNC HealthScore, in patients undergoing cancer treatment (ClinicalTrials.gov identifier NCT04923997). We present feasibility, acceptability, and preliminary outcome data. METHODS: HealthScore is a six-month, theory-based, multicomponent intervention delivered through participant-driven coaching sessions. For the pilot study, participants were provided a Fitbit, responded to weekly symptom and physical function digital surveys, and met with a health coach weekly to develop and monitor goals. Coaching notes were discussed in weekly interdisciplinary team meetings and provided back to the treating oncology team. Symptom alerts were monitored and triaged through a study resource nurse to relevant supportive care services. Feasibility was determined based on intervention enrollment and completion. Acceptability was based on satisfaction with coaching and Fitbit-wearing and was informed by semistructured exit interviews. Outcomes evaluated for signs of improvement included several PROMIS (Patient-Reported Outcomes Measurement Information System) measures, including the primary intervention target, physical function. RESULTS: From May 2020 to March 2022, 50 participants completed the single-arm pilot. Feasibility was high: 66% enrolled and 71% completed the full intervention. Participants reported an average of 4.8 and 4.7 (out of 5) on the acceptability of coaching calls and using the Fitbit, respectively. Physical function scores rose 3.1 points (SE = 1.1) from baseline to 3 months, and 4.3 (SE = 1.0) from baseline to 6 months, above established minimal clinically important difference (MCID). Improvements above MCID were also evident in anxiety and depression, and smaller improvements were demonstrated for emotional support, social isolation, cognitive function, symptom burden, and self-efficacy. DISCUSSION: HealthScore shows feasibility, acceptability, and promising preliminary outcomes. Randomized studies are underway to determine the efficacy of preserving physical function in patients with advanced cancer.

Chemotherapy supply chain management, safe-handling and disposal in Ethiopia: the case of Tikur Anbessa specialized hospital.

Optimal chemotherapy management is substandard in low and middle-income countries. We aimed to identify major gaps to design interventional strategies for improved chemotherapy management at Tikur Anbessa Specialized Hospital (TASH), Ethiopia. This study was conducted using an observational checklist, open-ended questions, record review, and key informant interviews of department heads and focal persons at TASH. Findings were categorized into specific themes that developed. Chemotherapy represented 60.2% of the hospital medication budget. Drug utilization was quantified via monthly consumption documentation and forecasting. However, unreliable data resulted in frequent stockouts (unavailability of the item when it is needed) of chemotherapy with only 67.8% availability. Thirteen healthcare personnel (9 nurses, 2 pharmacists and 2 hospital cleaners) were interviewed: all clinical staff but neither of hospital cleaners believed that they were at risk of hazardous agents. Challenges identified included inadequate and frequent stockouts (unavailability of the item when it is needed) of personal protective equipment, lack of standardized guidelines for chemotherapy handling, admixture, and disposal, lack of designated preparation rooms, and lack of training. All nine nurses handled chemotherapy admixtures despite only two nurses previously receiving in-service training. Most of the participants had never witnessed the disposal of anticancer drugs. Prompted by the results of this study, a dialogue was initiated among members of TASH, the American Cancer Society and the University of North Carolina to implement action-oriented projects to address the gaps identified at TASH. These gaps directly and indirectly affect care and treatment outcomes of patients at a large cancer center. Collaborations with well-resourced centers are potential models for improving chemotherapy management.

Oral adherence in adults with acute myeloid leukemia (AML): results of a mixed methods study.

INTRODUCTION: The incidence of AML is increasing, in part due to an aging population. Since 2017, eight novel agents have been introduced, 6 of which are oral: midostaurin, enasidenib, ivosidenib, gilteritinib, glasdegib, and venetoclax. With an increase in oral medications (OMs), patients face associated side effects that accompany OMs, which often decreases adherence. We aimed to identify and summarize adherence to OMs in this population. METHODS: Our mixed method design used focus groups (FG) and patient surveys. After IRB approval, 11 patients and 4 caregivers participated in 4 FGs. Themes from the FGs were used to develop a 37-item OMs adherence needs assessment. Participants were recruited and consented at three cancer centers to complete surveys (online, at the clinic, hospital, or from home). RESULTS: A total of 100 patients completed OMs survey. The number of pills to be taken was the most frequent and troublesome challenge. The most frequently reported interventions that would improve patient adherence were smaller pills, easier packaging, and scheduling assistance. Nearly 33% of patients indicated they skip OMs dose altogether when they forget to take it. Younger patients (< 65 years) were more accepting of taking oral compared with intravenous medications (p = .03). CONCLUSION: This study represents the first assessment of OMs adherence in adults with AML. Findings provide the basis for further exploration of interventions to enhance and increase adherence to OMs regimens.

Understanding Barriers to Oral Therapy Adherence in Adults With Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a disease of older adults, with a median age at diagnosis of 68 years. The availability of oral anticancer medications has increased, although the standard treatment for AML remains in intravenous form. We aim to identify barriers to adherence to oral medications in patients with AML and proposed solutions for improvements. Following institutional review board approval, patients with AML and their caregivers were recruited to participate in focus groups. Sessions were digitally recorded, transcribed verbatim, and analyzed for thematic content using Dedoose qualitative software. 11 patients (five < 65 years; six ≥ 65 years) and 4 caregivers participated in these sessions. Three central themes emerged: 1) medication adherence challenges, 2) managing an oral adherence plan, and 3) strategies to improve oral adherence. Participants recommended written schedules, taking medications around meals, and using pillboxes and alarms. We believe that patients are an important source of insight into barriers and solutions to oral medication adherence.

Chalepin: A Compound from Ruta angustifolia L. Pers Exhibits Cell Cycle Arrest at S phase, Suppresses Nuclear Factor-Kappa B (NF-κB) Pathway, Signal Transducer and Activation of Transcription 3 (STAT3) Phosphorylation and Extrinsic Apoptotic Pathway in Non-small Cell Lung Cancer Carcinoma (A549).

BACKGROUND: Plants have been a major source of inspiration in developing novel drug compounds in the treatment of various diseases that afflict human beings worldwide. Ruta angustifolia L. Pers known locally as Garuda has been conventionally used for various medicinal purposes such as in the treatment of cancer. OBJECTIVE: A dihydrofuranocoumarin named chalepin, which was isolated from the chloroform extract of the plant, was tested on its ability to inhibit molecular pathways of human lung carcinoma (A549) cells. MATERIALS AND METHODS: Cell cycle analysis and caspase 8 activation were conducted using a flow cytometer, and protein expressions in molecular pathways were determined using Western blot technique. RESULTS: Cell cycle analysis showed that cell cycle was arrested at the S phase. Further studies using Western blotting technique showed that cell cycle-related proteins such as cyclins, cyclin-dependent kinases (CDKs), and inhibitors of CDKs correspond to a cell cycle arrest at the S phase. Chalepin also showed inhibition in the expression of inhibitors of apoptosis proteins. Nuclear factor-kappa B (NF-κB) pathway, signal transducer and activation of transcription 3 (STAT-3), cyclooxygenase-2, and c-myc were also downregulated upon treatment with chalepin. Chalepin was found to induce extrinsic apoptotic pathway. Death receptors 4 and 5 showed a dramatic upregulation at 24 h. Analysis of activation of caspase 8 with the flow cytometer showed an increase in activity in a dose- and time-dependent manner. Activation of caspase 8 induced cleavage of BH3-interacting domain death agonist, which initiated a mitochondrial-dependent or -independent apoptosis. CONCLUSION: Chalepin causes S phase cell cycle arrest, NF-κB pathway inhibition, and STAT-3 inhibition, induces extrinsic apoptotic pathway, and could be an excellent chemotherapeutic agent. SUMMARY: This study reports the capacity of an isolated bioactive compound known as chalepin to suppress the nuclear factor kappa-light-chain-enhancer of activated B cells pathway, signal transducer and activation of transcription 3, and extrinsic apoptotic pathway and also its ability to arrest cell cycle in S phase. This compound was from the leaves of Ruta angustifolia L. Pers. It provides new insight on the ability of this plant in suppressing certain cancers, especially the nonsmall cell lung carcinoma according to this study.

Chalepin: isolated from Ruta angustifolia L. Pers induces mitochondrial mediated apoptosis in lung carcinoma cells.

BACKGROUND: Cancer has been one of the leading causes of mortality in this era. Ruta angustifolia L. Pers has been traditionally used as an abortifacient, antihelmintic, emmenagogue and ophthalmic. In Malaysia and Singapore, the local Chinese community used it for the treatment of cancer. METHODS: In this study, the methanol and fractionated extracts (hexane, chloroform, ethyl acetate and water) of R. angustifolia were tested for its cytotoxicity using the sulforhodamide (SRB) cytotoxicity assay against HCT-116, A549, Ca Ski and MRC5 cell lines. Chemical isolation was carried out by using the high performance liquid chromatography (HPLC) and the isolated compounds were tested for its cytotoxicity against A549 cell line. Cellular and nuclear morphological changes were observed in the cells using phase contrast microscopy and Hoechst/PI fluorescent staining. The externalisation of phosphatidylserine was observed through FITC-labelling Annexin V/PI assay whilst DNA fragmentation was observed through the TUNEL assay. Other indication of apoptosis occuring through the mitochondrial pathway were the attenuation of mitochondrial membrane potential and increase in ROS production. Activation of caspase 9 and 3 were monitored. Western blot analysis was done to show the expression levels of apoptotic proteins. RESULTS: The chloroform extract (without chlorophyll) exhibited the highest cytotoxic activity with IC50 of 10.1 ± 0.15 µg/ml against A549 cell line. Further chemical investigation was thus directed to this fraction which led to the isolation of 12 compounds identified as graveoline, psoralen, kokusaginine, methoxysalen, bergapten, arborinine, moskachan B, chalepin, moskachan D, chalepensin, rutamarin and neophytadiene. Among these compounds, chalepin exhibited excellent cytotoxicity against A549 cell line with an IC50 value of 8.69 ± 2.43 µg/ml (27.64 µM). In western blot analysis, expression of p53, truncated Bid, Bax and Bak while the anti-apoptotic proteins Bcl-2, survivin, XIAP, Bcl-XL,cFLIP decreased in a time-dependent manner when A549 cells were treated with 36 µg/ml of chalepin. In addition, the level of PARP was found to decrease. CONCLUSION: Hence these findings indicated that chalepin-induced cell death might involve the intrinsic mitochodrial pathway resulting in the upregulation of pro-apoptotic proteins and downregulation of anti-apoptotic proteins. Thus, chalepin could be an excellent candidate for the development of an anticancer agent.

Antioxidant Capacity, Cytotoxicity, and Acute Oral Toxicity of Gynura bicolor.

Gynura bicolor (Compositae) which is widely used by the locals as natural remedies in folk medicine has limited scientific studies to ensure its efficacy and nontoxicity. The current study reports the total phenolic content, antioxidant capacity, cytotoxicity, and acute oral toxicity of crude methanol and its fractionated extracts (hexane, ethyl acetate, and water) of G. bicolor leaves. Five human colon cancer cell lines (HT-29, HCT-15, SW480, Caco-2, and HCT 116), one human breast adenocarcinoma cell line (MCF7), and one human normal colon cell line (CCD-18Co) were used to evaluate the cytotoxicity of G. bicolor. The present findings had clearly demonstrated that ethyl acetate extract of G. bicolor with the highest total phenolic content among the extracts showed the strongest antioxidant activity (DPPH radical scavenging assay and metal chelating assay), possessed cytotoxicity, and induced apoptotic and necrotic cell death, especially towards the HCT 116 and HCT-15 colon cancer cells. The acute oral toxicity study indicated that methanol extract of G. bicolor has negligible level of toxicity when administered orally and has been regarded as safe in experimental rats. The findings of the current study clearly established the chemoprevention potential of G. bicolor and thus provide scientific validation on the therapeutic claims of G. bicolor.

Phase I trial of a multi-epitope-pulsed dendritic cell vaccine for patients with newly diagnosed glioblastoma.

BACKGROUND: This study evaluated the safety and immune responses to an autologous dendritic cell vaccine pulsed with class I peptides from tumor-associated antigens (TAA) expressed on gliomas and overexpressed in their cancer stem cell population (ICT-107). METHODS: TAA epitopes included HER2, TRP-2, gp100, MAGE-1, IL13Rα2, and AIM-2. HLA-A1- and/or HLA-A2-positive patients with glioblastoma (GBM) were eligible. Mononuclear cells from leukapheresis were differentiated into dendritic cells, pulsed with TAA peptides, and administered intradermally three times at two-week intervals. RESULTS: Twenty-one patients were enrolled with 17 newly diagnosed (ND-GBM) and three recurrent GBM patients and one brainstem glioma. Immune response data on 15 newly diagnosed patients showed 33 % responders. TAA expression by qRT-PCR from fresh-frozen tumor samples showed all patient tumors expressed at least three TAA, with 75 % expressing all six. Correlations of increased PFS and OS with quantitative expression of MAGE1 and AIM-2 were observed, and a trend for longer survival was observed with gp100 and HER2 antigens. Target antigens gp100, HER1, and IL13Rα2 were downregulated in recurrent tumors from 4 HLA-A2+ patients. A decrease in or absence of CD133 expression was seen in five patients who underwent a second resection. At a median follow-up of 40.1 months, six of 16 ND-GBM patients showed no evidence of tumor recurrence. Median PFS in newly diagnosed patients was 16.9 months, and median OS was 38.4 months. CONCLUSIONS: Expression of four ICT-107 targeted antigens in the pre-vaccine tumors correlated with prolonged overall survival and PFS in ND-GBM patients. The goal of targeting tumor antigens highly expressed on glioblastoma cancer stem cells is supported by the observation of decreased or absent CD133 expression in the recurrent areas of gadolinium-enhanced tumors.
