Natural killer (NK) cells are important early responders against viral infections. Changes in metabolism are crucial to fuel NK cell responses, and altered metabolism is linked to NK cell dysfunction in obesity and cancer. However, very little is known about the metabolic requirements of NK cells during acute retroviral infection and their importance for antiviral immunity. Here, using the Friend retrovirus mouse model, we show that following infection NK cells increase nutrient uptake, including amino acids and iron, and reprogram their metabolic machinery by increasing glycolysis and mitochondrial metabolism. Specific deletion of the amino acid transporter Slc7a5 has only discrete effects on NK cells, but iron deficiency profoundly impaires NK cell antiviral functions, leading to increased viral loads. Our study thus shows the requirement of nutrients and metabolism for the antiviral activity of NK cells, and has important implications for viral infections associated with altered iron levels such as HIV and SARS-CoV-2.

Introduction: The authors compared the availability of integrative medicine therapies in National Cancer Institute-Designated Comprehensive Cancer Centers and community hospitals. Methods: The authors reviewed 51 Comprehensive Cancer Center and 100 community hospital websites and collected race and median household income data for community hospital populations. Results: Availability of acupuncture (56% vs. 76.5%, p = 0.01), meditation (63% vs. 82.4%, p = 0.02), and music therapy (55% vs. 74.5%, p = 0.02) was significantly lower at community hospitals compared with Comprehensive Cancer Centers. Integrative medicine availability was also significantly lower in community hospitals serving lower-income populations. Conclusion: Equitable access to evidence-based integrative medicine in community hospitals is needed.

Background: Patients with cancer are particularly vulnerable to stress and anxiety during the COVID-19 pandemic. Social distancing is critical for patients with cancer; however, it can also reduce their access to psychosocial coping resources. Objective: The aim of this study was to explore patient experiences to generate a model of how virtual mind-body programs can support the psychosocial well-being of patients with cancer. Methods: We conducted a qualitative study among patients (aged ≥18 years) who participated in a virtual mind-body program offered by a National Cancer Institute–designated Comprehensive Cancer Center during the COVID-19 pandemic. The program consisted of mind-body group therapy sessions of fitness, yoga, tai chi, dance therapy, music therapy, and meditation. Live integrative medicine clinicians held each session via Zoom videoconferencing for 30-45 minutes. In semistructured phone interviews (n=30), patients were asked about their overall impressions and perceptions of the benefits of the sessions, including impacts on stress and anxiety. Interviews were analyzed using grounded theory. Results: Among the 30 participants (average age 64.5 years, SD 9.36, range 40-80, 29 female), three major themes were identified relating to experiences in the virtual mind-body program: (1) the sessions helped the patients maintain structured routines and motivated them to adhere to healthy behaviors; (2) the sessions enhanced coping with COVID-19-related-stressors, allowing patients to “refocus” and “re-energize”; and (3) the sessions allowed patients to connect, fostering social relationships during a time of isolation. These themes informed the constructs of a novel behavioral-psychological-social coping model for patients with cancer. Conclusions: Virtual mind-body programming supported patients with cancer during the COVID-19 pandemic through a behavioral-psychological-social coping model by enhancing psychological coping for external stressors, supporting adherence to motivation and health behaviors, and increasing social connection and camaraderie. These programs have potential to address the behavioral, psychological, and social challenges faced by patients with cancer during and beyond the COVID-19 pandemic. The constructs of the conceptual model proposed in this study can inform future interventions to support isolated patients with cancer. Further clinical trials are needed to confirm the specific benefits of virtual mind-body programming for the psychosocial well-being and healthy behaviors of patients with cancer.

Pain and insomnia often co-occur and impair the quality of life in cancer survivors. This study evaluated the effect of acupuncture versus cognitive behavioral therapy for insomnia (CBT-I) on pain severity among cancer survivors with comorbid pain and insomnia. Using data from the CHOICE trial that compared acupuncture versus CBT-I for insomnia among cancer survivors, we analyzed the effect of interventions on pain outcomes in 70 patients with moderate to severe baseline pain. Interventions were delivered over eight weeks. We assessed average pain severity (primary outcome) and pain interference at baseline, week 8, and week 20. We further defined insomnia and pain responders as patients who achieved clinically meaningful improvement in insomnia and pain outcomes, respectively, at week 8. We found that compared with baseline, the between-group difference (-1.0, 95% CI -1.8 to -0.2) was statistically significant favoring acupuncture for reduced pain severity at week 8 (-1.4, 95% CI -2.0 to -0.8) relative to CBT-I (-0.4, 95% CI-1.0 to 0.2). Responder analysis showed that 1) with acupuncture, insomnia responders reported significantly greater pain reduction from baseline to week 4, compared with insomnia non-responders (-1.5, 95% CI -2.7 to -0.3); 2) with CBT-I, pain responders reported significantly greater insomnia reduction at week 8, compared with pain non-responders (-4.7, 95% CI -8.7 to -1.0). These findings suggest that among cancer survivors with comorbid pain and insomnia, acupuncture led to rapid pain reductions, which contributed to a decrease in insomnia, whereas CBT-I had a delayed effect on pain, possibly achieved by insomnia improvement.

Objective: In response to the national opioid crisis, governmental and medical organizations have called for broader insurance coverage of acupuncture to improve access to nonpharmacologic pain therapies, especially in cancer populations, where undertreatment of pain is prevalent. We evaluated whether cancer patients would be willing to use insurance-covered acupuncture for pain. Design and Setting: We conducted a cross-sectional survey of cancer patients with pain at one academic center and 11 community hospitals. Methods: We used logistic regression models to examine factors associated with willingness to use insurance-covered acupuncture for pain. Results: Among 634 cancer patients, 304 (47.9%) reported willingness to use insurance-covered acupuncture for pain. In univariate analyses, patients were more likely to report willingness if they had severe pain (odds ratio [OR] = 1.59, 95% confidence interval [CI] = 1.03–2.45) but were less likely if they were nonwhite (OR = 0.59, 95% CI = 0.39–0.90) or had only received high school education or less (OR = 0.46, 95% CI = 0.32–0.65). After adjusting for attitudes and beliefs in multivariable analyses, willingness was no longer significantly associated with education (adjusted OR [aOR] = 0.78, 95% CI = 0.50–1.21) and was more negatively associated with nonwhite race (aOR = 0.49, 95% CI = 0.29–0.84). Conclusions: Approximately one in two cancer patients was willing to use insurance-covered acupuncture for pain. Willingness was influenced by patients’ attitudes and beliefs, which are potentially modifiable through counseling and education. Further research on racial disparities is needed to close the gap in utilization as acupuncture is integrated into insurance plans in response to the opioid crisis.
