RESUMEN

Because equine tendinopathies are slow to heal and often recur, therapeutic strategies are being considered that aid tendon repair. Given the success of utilizing vitamin C to promote tenogenesis in other species, we hypothesized that vitamin C supplementation would produce dose-dependent improvements in the tenogenic properties of tendon proper (TP) and peritenon (PERI) cells of the equine superficial digital flexor tendon (SDFT). Equine TP- and PERI-progenitor-cell-seeded fibrin three-dimensional constructs were supplemented with four concentrations of vitamin C. The gene expression profiles of the constructs were assessed with 3'-Tag-Seq and real-time quantitative polymerase chain reaction (RT-qPCR); collagen content and fibril ultrastructure were also analyzed. Moreover, cells were challenged with dexamethasone to determine the levels of cytoprotection afforded by vitamin C. Expression profiling demonstrated that vitamin C had an anti-inflammatory effect on TP and PERI cell constructs. Moreover, vitamin C supplementation mitigated the degenerative pathways seen in tendinopathy and increased collagen content in tendon constructs. When challenged with dexamethasone in two-dimensional culture, vitamin C had a cytoprotective effect for TP cells but not necessarily for PERI cells. Future studies will explore the effects of vitamin C on these cells during inflammation and within the tendon niche in vivo.

RESUMEN

CONTEXT: The COVID-19 pandemic placed the issue of resource utilization front and center. Our comprehensive cancer center developed a Goals of Care Rapid Response Team (GOC RRT) to optimize resource utilization balanced with goal-concordant patient care. OBJECTIVES: Primary study objective was to evaluate feasibility of the GOC RRT by describing the frequency of consultations that occurred from those requested. Secondary objectives included adherence to consultation processes in terms of core team member participation and preliminary efficacy in limiting care escalation. METHODS: We conducted a retrospective chart review of patients referred to GOC RRT (3/23/2020-9/30/2020). Analysis was descriptive. Categorical variables were compared with Fisher's exact or Chi-Square tests and continuous variables with Mann-Whitney U tests. RESULTS: A total of 89 patients were referred. Eighty-five percent (76 of 89) underwent a total of 95 consultations. Median (range) patient age was 61 (49, 69) years, 54% (48 of 89) male, 19% (17 of 89) Hispanic, 48% (43/89) White, 73% (65 of 89) married/partnered and 66% (59 of 89) Christian. Hematologic malignancies and solid tumors were evenly balanced (53% [47/89] vs. 47% [42 of 89, P = 0.199]). Most patients (82%, 73 of 89) had metastatic disease or relapsed leukemia. Seven percent (6 of 89) had confirmed COVID-19. Sixty-nine percent (61 of 89) died during the index hospitalization. There was no statistically significant difference in demographic or clinical characteristics among groups (no consultation, 1 consultation, >1 consultation). Core team members were present at 64% (61 of 95) of consultations. Care limitation occurred in 74% (56 of 76) of patients. CONCLUSION: GOC RRT consultations were feasible and associated with care limitation. Adherence to core team participation was fair.

RESUMEN

CONTEXT: Current guidelines recommend early referral to palliative care for patients with advanced cancer; however, no studies have examined the optimal timing of referral from the patients' perspective. OBJECTIVES: To examine patients' perceptions of timeliness of referral and its association with survival among patients with advanced cancer referred to an outpatient supportive care (SC) clinic. METHODS: This cross-sectional prospective study in an SC clinic at a comprehensive cancer center included patients aged 18 years or older with locally advanced, recurrent, or metastatic cancer. Patients were asked to complete an anonymous survey regarding the timeliness and perceived usefulness of SC referral within four weeks of their first SC consultation. RESULTS: Of 253 eligible patients, 209 (83%) enrolled in the study and 200 completed the survey. Median survival was 10.3 months. Most patients (72%) perceived that referral occurred "just in time," whereas 21% felt it was "late," and 7% felt "early." A majority (83%) found the referral useful, and 88% would recommend it to other patients with cancer. The perception of being referred early was associated with lower reported levels of pain (P = 0.043), fatigue (P = 0.004), drowsiness (P = 0.005), appetite loss (P = 0.041), poor well-being (P = 0.041), and lower physical (P = 0.001) and overall symptom distress (P = 0.001). No other associations were found between perceived timeliness and usefulness and patients' baseline characteristics. CONCLUSION: Most patients with a median survival of 10 months perceived that SC referral was timely and useful. Patient care needs rather than the timing of advanced cancer diagnosis drove this perception of referral timing. Lower symptom burden was associated with the perception of being referred to early.

RESUMEN

CONTEXT: There is limited literature regarding outpatient palliative care and factors associated with unscheduled clinic visits. OBJECTIVES: To compare characteristics of patients with unscheduled vs. scheduled outpatient palliative care clinic visits. METHODS: Medical records of 183 unscheduled cancer new outpatients and 104 unscheduled follow-up (FU) patients were compared with random samples of 361 and 314 scheduled new patients and FU patients, respectively. We gathered data on demographics, symptoms, daily opioid usage, and performance status. RESULTS: Compared with scheduled new patients, unscheduled new patients had worse Edmonton Symptom Assessment Scale subscores for pain (P < 0.001), fatigue (P = 0.002), nausea (P = 0.016), depression (P = 0.003), anxiety (P = 0.038), drowsiness (P = 0.002), sleep (P < 0.001), and overall feeling of well-being (P = 0.001); had a higher morphine equivalent daily dose of opioids (median of 45 mg for unscheduled vs. 30 mg for scheduled; P < 0.001); and were more likely to be from outside the greater Houston area (P < 0.001). Most unscheduled and scheduled new and FU visits were for uncontrolled physical symptoms. Unscheduled FU patients, compared with scheduled FU patients, had worse Edmonton Symptom Assessment Scale subscores for pain (P < 0.001), fatigue (P < 0.001), depression (P = 0.002), anxiety (P = 0.004), drowsiness (P = 0.010), appetite (P = 0.023), sleep (P = 0.022), overall feeling of well-being (P < 0.001), and higher morphine equivalent daily dose of opioid (median of 58 mg for unscheduled FU visits vs. 40 mg for scheduled FU visits; P = 0.054). CONCLUSION: Unscheduled new FU patients have higher levels of physical and psychosocial distress and higher opioid intake. Outpatient palliative care centers should consider providing opportunities for walk-in visits for timely management and close monitoring of such patients.

RESUMEN

Background: Despite the high frequency, severity, and effects of cancer-related fatigue (CRF) on the quality of life (QoL) of patients with cancer, limited treatment options are available. The primary objective of this study was to compare the effects of oral Panax ginseng extract (PG) and placebo on CRF. Secondary objectives were to determine the effects of PG on QoL, mood, and function. Methods: In this randomized, double-blind, placebo-controlled study, patients with CRF ≥4/10 on the Edmonton Symptom Assessment System (ESAS) were eligible. Based on a pilot study, we randomized patients to receive either 400 mg of standardized PG twice daily or a matching placebo for 28 days. The primary end point was change in the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) subscale from baseline to day 29. Results: Of 127 patients, 112 (88.2%) were evaluable. The mean (SD) FACIT-F subscale scores at baseline, day 15, and day 29 were 22.4 (10.1), 29.9 (10.6), and 30.1 (11.6) for PG (P<.001), and 24.0 (9.4), 30.0 (10.1), and 30.4 (11.5) for placebo (P<.001). Mean (SD) improvement in the FACIT-F subscale at day 29 was not significantly different in the PG than in the placebo group (7.5 [12.7] vs 6.5 [9.9]; P=.67). QoL, anxiety, depression, symptoms, and functional scores were not significantly different between the PG and placebo groups. Improvement in the FACIT-F subscale correlated with baseline scores (P=.0005), Hospital Anxiety and Depression Scale results (P=.032), and sex (P=.023). There were fewer any-grade toxicities in the PG versus placebo group (28/63 vs 33/64; P=.024). Conclusions: Both PG and placebo result in significant improvement in CRF. PG was not significantly superior to placebo after 4 weeks of treatment. There is no justification to recommend the use of PG for CRF. Further studies are needed. Trial Registration: ClinicalTrials.gov identifier: NCT01375114.

RESUMEN

BACKGROUND: Integration of palliative care (PC) in oncology have been found to improve symptom distress, quality of life, and survival in patients with advanced cancer. Early integration is most appropriate in the outpatient setting. However, most PC services in the United States do not have an outpatient component. Our study aims to provide a snapshot of the type of patients and families who are referred to this novel setting for the delivery of early PC. CONCLUSION: Traditionally, PC has been delivered predominantly to patients with advanced disease and to aid in transition to end of life. In recent years, outpatient centers have dramatically changed the nature of PC work as in our snapshot, which shows that in addition to patients regarded as more traditional patients, such as those transitioning to end of life, there are now patients who come in very soon after arrival to a cancer center requiring specialized care to address a variety of symptom and educational needs, thus requiring adaptation of structure and processes to allow access for frequent follow-ups, counseling, and flexibility for walk-in visits. Our findings suggest that Supportive Care Clinic needs to practice in a very different way, which requires certain skills and assessment tools that are not conventionally present in traditional oncology clinic settings. More research is needed to identify the type of patients who would benefit most from a PC referral.

RESUMEN

PURPOSE: Palliative care (PC) training and integration with oncology care remain suboptimal. Current attitudes and beliefs of the oncology trainees regarding PC are not fully known. This study was undertaken in an attempt to address this issue. PARTICIPANTS AND METHODS: We conducted a survey to determine awareness of PC among graduate medical trainees at a comprehensive cancer center with an established PC program. One hundred seventy oncology trainees who completed$9 months of training in medical, surgical, gynecologic, and radiation oncology fellowships and residency programs during the 2013 academic year completed an online questionnaire. Descriptive, univariable, and multivariable analyses were performed. RESULTS: The response rate was 78% (132 of 170 trainees); 10 trainees without hands-on patient care were excluded. Medical (53 of 60 [88%]), gynecologic (six of six [100%]), and radiation oncology (20 of 20 [100%]) trainees reported more awareness of PC compared with surgical oncology (22 of 36 [61%]) trainees (P = .001). One hundred twelve of 122 (92%) perceived PC as beneficial to patients and families. One hundred eight of 122 (89%) perceived that PC can reduce health care costs, 78 (64%) believed that PC can increase survival, and 90 (74%) would consult PC for a patient with newly diagnosed cancer with symptoms. Eighty-two trainees (67%) believed a mandatory PC rotation is important. Trainees with previous exposure to PC rotations were more aware of the role of PC services than were trainees without PC rotation (96% [46 of 48] v 74% [55 of 74]; P = .005, respectively). CONCLUSION: Surgical trainees and trainees without previous PC rotation had significantly less awareness of PC. Overall, trainees perceived PC as beneficial to patients and capable of reducing costs while increasing survival; they also supported early PC referrals and endorsed a mandatory PC rotation.
