RESUMEN

BACKGROUND: For cancer survivors, there is a paucity of fear of recurrence (FOR) interventions that integrate empirically supported mind-body and psychological skills for managing FOR and are delivered in scalable formats. OBJECTIVE: To adapt an evidence-based resiliency intervention to address FOR among cancer survivors. METHODS: A multidisciplinary team of researchers, clinicians, and patient stakeholders followed an iterative intervention adaptation process (ORBIT). In Step 1, we sought to define key FOR management skills through a literature review and feedback from stakeholders. In Step 2, we integrated findings into a treatment manual and refined procedures for in-person delivery to groups of cancer survivors, defined as adults who had completed primary cancer treatment for non-metastatic cancer. In Step 3, we conducted a single arm trial to assess initial acceptability and change in FOR severity with 23 cancer survivors (N=4 intervention groups). In Step 4, we conducted additional qualitative interviews with 28 cancer survivors (N=6 focus groups stratified by FOR severity, N=15 individual interviews) to define adaptive and maladaptive strategies for coping with FOR and to identify preferences for delivery. In Step 5, we refined the treatment manual and procedures for testing in a future pilot randomized feasibility trial. RESULTS: We identified critical feedback using a combination of qualitative and quantitative methods. The single arm trial suggested preliminary feasibility and sustained reductions in FOR severity, yet need for refinement (i.e., eligibility, delivery modality), prompting additional qualitative interviews for further targeting. The resulting intervention (IN FOCUS) is comprised of virtual, synchronous, group-delivered sessions that offer an integrated approach to FOR management by teaching cognitive-behavioral techniques, meditation, relaxation training, adaptive health behaviors, and positive psychology skills. Sessions are targeted by applying skills to FOR and associated healthcare engagement. CONCLUSIONS: IN FOCUS is a targeted intervention for teaching mind-body resiliency skills to groups of cancer survivors with elevated FOR. Next steps are testing feasibility in a pilot randomized trial.

RESUMEN

PURPOSE: Chronic obstructive pulmonary disease (COPD) is associated with multiple psychosocial and behavioral factors. Prior research suggests that mind-body interventions may support the development and maintenance of healthy behaviors and improve health-related quality-of-life in such patients. We sought to qualitatively explore cognitive, psychosocial, and behavioral changes in patients with COPD who participated in two different mind-body interventions compared to an education control. METHODS: We analyzed semi-structured qualitative exit interviews from a prospective, randomized pilot trial (N = 123) investigating 12-weeks of Tai Chi (TC) vs. mind-body breathing (MBB) vs. education (EDU) control in patients with moderate-severe COPD. TC involved traditional movements, that integrate meditative breathing, while MBB focused mainly on meditative breathing techniques alone. Interviews were audio-recorded and transcribed verbatim. Qualitative analysis of randomly selected transcripts was performed by two independent reviewers using an iterative process to identify emergent themes informed by grounded theory methods until thematic saturation was reached. RESULTS: A total of 66 transcripts were reviewed (N = 22 TC, N = 22 MBB, N = 22 EDU). Participants were mean age = 68.1 years, GOLD Stage = 2.3, baseline FEV11 percent predicted mean (SD): 58% (13.4), 42.4% female. We identified six frequently mentioned themes: 1) overall awareness and understanding, 2) self-care knowledge, skills and behaviors, 3) behavior-related neurocognitive concepts, 4) physical function, 5) psychological well-being, and 6) social support/social function. Compared to EDU, more participants in TC and MBB noted improvements in awareness of self and the mind-body connection (e.g., body and breath awareness), knowledge of breathing techniques and integration of self-care skills with daily activities, self-efficacy for symptom management (particularly managing anxiety and dyspnea), acceptance of disease, physical function improvements (e.g., endurance, dyspnea, fatigue), and psychological well-being (particularly relaxation, emotion regulation and decreased reactivity). Compared to MBB, those in TC shared more intention to continue with self-care behaviors, physical activity self-efficacy, and improved flexibility. All three groups, including EDU, noted increased social support and knowledge of disease. Those in EDU, however, had fewer mentions of processes related to behavior change, and less concrete changes in neurocognitive, psychological, and physical function domains. CONCLUSIONS: Mind-body interventions including meditative breathing may impact behavior-related neurocognitive and emotional factors that improve self-care management and support positive behavioral changes in patients with COPD. TRIAL REGISTRATION: This trial is registered in Clinical Trials.gov, ID number NCT01551953.

RESUMEN

OBJECTIVE: Interventions for fear of recurrence (FOR) of cancer have nominal effects, perhaps due to limited integration of empirically supported skills. This pilot trial tested the acceptability and feasibility of a multimodal, mind-body resiliency intervention targeting FOR among survivors of various cancers. METHODS: Early stage cancer survivors 3-30 months post-treatment were recruited to participate in an eight-session in-person mind-body resiliency group intervention that taught relaxation skills, cognitive-behavioral techniques, healthy lifestyle behaviors, mindfulness meditation, and positive psychology skills all targeted for FOR. Primary outcomes were feasibility (enrollment rate, session attendance, survey completion, skills practice) and acceptability (enjoyableness, convenience, helpfulness, relevance). Patient-reported outcomes (FOR, uncertainty intolerance, cancer-related uncertainty, perceived stress, resiliency, positive affect, and coping skills) were collected at baseline, post-intervention, +1 month, and +3 months. Exit interviews assessed survivors' reported benefits. RESULTS: Participants (N = 4 groups, 23 survivors, enrollment response rate = 58%) included survivors of seven common cancer types who were on average 12 months post-treatment. Attendance was high (M = 6.1 sessions), and 96% of survivors completed all surveys. Sustained increases in relaxation skills practice 3+ days/week were reported (baseline = 16%, post-intervention = 76%, +3 months = 71%). Most sessions (87%) were rated as highly or very highly acceptable. Moderate-to-large (d = 0.87) improvements in FOR severity were observed post-intervention (p < .01) and across assessments (p < .01), with similar changes observed in other patient-reported outcomes. Exit interviews revealed behavioral, cognitive, emotional, and existential benefits. CONCLUSIONS: The targeted mind-body resiliency intervention shows promising acceptability, feasibility, and favorable changes in FOR and coping skills practice. Further adaptation and testing in a randomized trial are warranted. ClinicalTrials.govRegistration Number: NCT03695406.

RESUMEN

In vitro exposure of neural progenitor cell (NPC) populations to reduced O(2) (e.g. 3% versus 20%) can increase their proliferation, survival and neuronal differentiation. Our objective was to determine if an acute (<1hr), in vivo exposure to intermittent hypoxia (AIH) alters expansion and/or differentiation of subsequent in vitro cultures of NPC from the subventricular zone (SVZ). Neonatal C57BL/6 mice (postnatal day 4) were exposed to an AIH paradigm (20×1 minute; alternating 21% and 10% O(2)). Immediately after AIH, SVZ tissue was isolated and NPC populations were cultured and assayed either as neurospheres (NS) or as adherent monolayer cells (MASC). AIH markedly increased the capacity for expansion of cultured NS and MASC, and this was accompanied by increases in a proliferation maker (Ki67), MTT activity and hypoxia-inducible factor-1α (HIF-1α) signaling in NS cultures. Peptide blockade experiments confirmed that proteins downstream of HIF-1α are important for both proliferation and morphological changes associated with terminal differentiation in NS cultures. Finally, immunocytochemistry and Western blotting experiments demonstrated that AIH increased expression of the neuronal fate determination transcription factor Pax6 in SVZ tissue, and this was associated with increased neuronal differentiation in cultured NS and MASC. We conclude that in vivo AIH exposure can enhance the viability of subsequent in vitro SVZ-derived NPC cultures. AIH protocols may therefore provide a means to "prime" NPC prior to transplantation into the injured central nervous system.
