Development and pilot testing of a clinic implementation program delivering physical activity electronic referrals to cancer survivors.

Provider physical activity referrals are recommended for cancer survivors, though barriers exist to clinical system integration. To develop and test ActivityChoice, an electronic referral (eReferral) clinic implementation program referring cancer survivors to physical activity programs of their choice. In Phase 1, we conducted semi-structured interviews with Cancer Center clinicians (n = 4) and cancer-focused physical activity program leaders (n = 3) assessing adaptations needed to implement an eReferral previously designed for another context. In Phase 2, we pilot-tested clinician-delivered referrals to survivors in two 12-week Plan, Do, Study, Act (PDSA) cycles. We examined feasibility using descriptive statistics (clinicians' adoption and engagement, patient referrals, and physical activity program enrollment) and acceptability through semi-structured interviews with enrolled clinicians (n = 4) and referred patients (n = 9). ActivityChoice included a secure referral webform, text message/email referral confirmations, clinician training/booster sessions, visual reminders, and referrals to in-person or virtual group physical activity programs. Results for each PDSA cycle respectively included: 41% (n = 7) and 53% (n = 8) of clinicians adopted ActivityChoice; 18 and 36 patients were referred; 39% (n = 7) and 33% (n = 12) of patients enrolled in programs, and 30% (n = 4) and 14% (n = 5) of patients deferred enrollment. Patients and clinicians appreciated the referrals and choices. A printed handout describing both programs was added to the clinic workflow for Cycle 2, which yielded more referrals, but lower program enrollment rates. Clinic-based eReferrals to choices of physical activity programs were feasible and acceptable by clinicians and patients. Added clinic workflow support may facilitate referrals.

Physical activity can improve the health, quality of life, and longevity among cancer survivors. Patients want to receive physical activity referrals and guidance from their cancer care team, but clinicians lack the knowledge, resources, time, and methods to counsel and refer their patients to community-based physical activity programs. One solution is to create a comprehensive electronic referral (eReferral) system giving cancer care clinicians the tools to support and refer their patients. We developed a simple eReferral that allows clinicians to refer patients to existing, evidence-based physical activity programs led by qualified exercise professions, LIVESTRONG at the YMCA (in-person) and Fit Cancer (virtual). We pilot tested the system with clinicians in two 12-week cycles. Clinicians were excited about the program and like the options they had to offer patients while providing suggestions on how we could better integrate it into their work environment. Patients appreciated the referral from their trusted cancer care clinician and appreciated choices of an in-person and virtual program to accommodate their preferences. To improve patient referrals and enrollment in physical activity programs, a more detailed printed handout that explains the benefits of physical activity in survivorship and describes each of the programs in detail may be helpful.

Benign Hand Tumors (Part I): Cartilaginous and Bone Tumors.

Background: Benign tumors of the hand present in a wide array of histological subtypes and compose most of the bony tissue tumors in the hand. This study evaluates the characteristics and treatment of benign bone tumors in light of one institution's experience. Methods: Histologically confirmed benign tumors of the hand were retrospectively identified using International Classification of Diseases codes from 1992 to 2015. A medical chart review was conducted to collect patient characteristics and tumor epidemiology and treatment. Results: A total of 155 benign bone tumors were identified. The median age of patients at the time of surgery was 39.9 ± 12.8 years. All bone tumors were located in the digits, and most were treated by intralesional curettage (n = 118, 76%). Pathologic fractures occurred in 79 bone tumors (51%). Conclusion: Enchondromas (n = 118, 76%) were the most common bone tumor in this series, whereas giant cell tumors were the most destructive and also had the highest recurrence rate (40%). Awareness of tumor features may help physicians with diagnosis, and awareness of recurrence rates is important when counseling patients.

Benign Hand Tumors (Part II): Soft Tissue Tumors.

Background: Benign soft-tissue tumors of the hand are more common than both their benign bone and malignant soft-tissue counterparts. This study evaluates the characteristics and treatment of benign soft tissue tumors in light of 1 institution's experience. Methods: Histologically confirmed benign soft-tissue tumors of the hand were retrospectively identified using International Classification of Disease codes from 1992 to 2015. A medical chart review was conducted to collect patient demographics, tumor epidemiology, and treatment. Results: A total of 199 soft-tissue tumors were identified. The median patient age at time of treatment was 47.4 ± 14.7 years in age. The majority of tumors were located in the digits (n = 168, 84%) and treated by excision (n = 191, 96%). Localized type tenosynovial giant cell tumors (n = 71, 36%) were the most common and had the highest rates of recurrence (8.5%) in this series. Other frequent histologies included hemangioma, schwannoma, and glomus tumors. Conclusion: Awareness and understanding of tumor characteristics may help physicians with diagnosis and treatment. There is an extensive variety of tumors, but the principles of clinical and imaging diagnosis are common to all of them. Marginal excision for the treatment pain, improvement of function, and cosmetic correction applies to all these tumors independent of the histology.

Wearable device use and technology preferences in cancer survivors with or at risk for atrial fibrillation.

Background: Cancer survivors face increased risk of heart disease, including atrial fibrillation (AF). Certain types of technology, such as consumer wearable devices, can be useful to monitor for AF, but little is known about wearables and AF monitoring in cancer survivor populations. Objective: The purpose of this study was to understand technology usage and preferences in cancer survivors with or at risk for AF, and to describe demographic factors associated with wearable device ownership in this population. Methods: Eligible patients completed a remote survey assessment regarding use of commercial wearable devices. The survey contained questions designed to assess commercial wearable device use, electronic health communications, and perceptions regarding the participant's cardiac health. Results: A total of 424 cancer survivors (mean age 74.2 years; 53.1% female; 98.8% white) were studied. Although most participants owned a smartphone (85.9%), only 31.8% owned a wearable device. Over half (53.5%) of cancer survivors were worried about their heart health. Overall, patients believed arrhythmias (79.7%) were the most important heart condition for a wearable to detect. Survivors reported being most willing to share blood pressure (95.6%) and heart rate (95.3%) data with their providers and were least willing to share information about their diet, weight, and physical activity using these devices. Conclusion: Understanding factors such as device ownership, usage, and heart health concerns in cancer survivors can play an important role in improving cardiovascular monitoring and its accessibility. Long-term patient outcomes may be improved by incorporating wearable devices into routine care of cancer survivors.

Soft-tissue Sarcoma of the Hand: Patient Characteristics, Treatment, and Oncologic Outcomes.

INTRODUCTION: The aim of this study was to describe patient characteristics, treatment, and oncologic outcomes of soft-tissue sarcomas (STSs) of the hand. METHODS: Sixty-nine STSs of the hand in adult patients treated at a tertiary referral center were retrospectively included. We describe patient and tumor characteristics along with oncologic outcomes. RESULTS: Epithelioid sarcoma (23%) was the most common histologic subtype, followed by synovial sarcoma (15%). Of all tumors, 17 (25%) were grade I, 22 (32%) were grade II, and 30 (44%) were grade III. The 5-year disease-free survival for epithelioid sarcomas was 75% with a disease survival of 100%, along with a metastatic rate of 15%. Of the patients with a synovial sarcoma, 40% developed metastases, and the 5-year disease-free survival was 68% and the 5-year disease survival was 73%. CONCLUSION: Hand STSs are aggressive tumors with a high metastatic potential. Even with adequate oncologic treatment, long-term clinical follow-up (10 years) in these tumors is advised. The treating surgical oncologist should not be deceived by their smaller size.

Trophic upgrading and mobilization of wax esters in microzooplankton.

Heterotrophic protists play pivotal roles in aquatic ecosystems by transferring matter and energy, including lipids, from primary producers to higher trophic predators. Using Oxyrrhis marina as a model organism, changes to the non-saponifiable protist lipids were investigated under satiation and starvation conditions. During active feeding on the alga Cryptomonas sp., the O. marina hexane soluble non-saponifiable fraction lipid profile reflected its food source with the observed presence of long chain mono-unsaturated fatty alcohols up to C25:1. Evidence of trophic upgrading in O. marina was observed with long chain mono-unsaturated fatty alcohol accumulation of up to C35:1. To the best of our knowledge, this is the first evidence that heterotrophic dinoflagellates are capable of producing ester derived alcohols and that dinoflagellates like O. marina are capable of synthesizing fatty alcohols up to C35. Additionally, we show evidence of trophic upgrading of lipids. During a 20-day resource deprivation, the lipid profile remained constant. During starvation, the mobilization of wax esters as energy stores was observed with long chain fatty alcohols mobilized first. Changes in lipid class profile and utilization of wax esters in O. marina provides insight into the types of lipids available for energy demand, the transfer of lipids through the base of marine food webs, and the catabolic response induced by resource deprivation.

Soft tissue sarcoma of the hand: Is unplanned excision a problem?

BACKGROUND: Soft tissue sarcoma (STS) of the hand are prone to unplanned excisions, altering oncologic outcomes. The aim of this study is to compare STS of the hand with initial treatment at an oncology center versus those initially treated at a non-oncology center. Additionally, we evaluated what factors were associated with oncologic outcomes. METHODS: We retrospectively identified patients with a STS of the hand using ICD-9 codes along with an institutional oncologic database. We included all adult patients with a non-metastatic STS of the hand (n = 64) with a median follow up of 4.0 years (IQR:1.7-10.0). RESULTS: Eight-three percent (n = 53) of tumors had an unplanned excision, of which one was treated at the oncology center. Patients treated primarily at an oncology center were older (57.6 vs. 43.6 years), had fewer operations and tended to have a larger tumors (median 4.7 cm vs. 3.0 cm) compared to those initially treated at a non-oncology center. The 5-year survival for patients treated at an oncology center was 60% compared to 89% in those initially treated at a non-oncology center. Worse disease-free survival was associated with positive final margins and subfascial tumors. CONCLUSION: Tumors with primary treatment at an oncology center were larger and presented in older patients, having worse overall survival compared to those initially treated at a non-oncology center. Initial treatment at a non-oncology center did not influence the oncologic outcomes, but lead to more re-excisions and amputations. Final tumor margins and tumor depth determined oncologic outcomes.
