National estimates of mental health service use and unmet needs among adult cancer survivors.

BACKGROUND: Cancer survivors are at elevated risk for developing mental health (MH) disorders. This study assessed MH service use and unmet service needs among a nationally representative sample of cancer survivors. METHODS: Respondents aged 18 to 64 years were identified from the 2015-2018 National Survey of Drug Use and Health data. Outcomes assessed past-year MH service use and self-reported unmet MH needs. Outcomes were compared between respondents who reported a cancer history (survivors) and those who did not (controls), descriptively and in adjusted analyses controlling for sociodemographic factors and health status. Analyses were stratified by age groups (18-34, 35-49, and 50-64 years). RESULTS: Comparing 3540 survivors with 149,843 controls, within each age group, a higher proportion of survivors than controls received any MH service (P values < .05); this difference persisted among those aged 35 to 49 years (P = .004) in fully adjusted models. Moreover, a higher proportion of survivors than controls reported an unmet need for MH care; this difference was larger among young adults aged 18 to 34 years (20.8% vs 9.0%; P < .001) than those aged 35 to 49 years (9.4% vs 5.3%; P < .001) and 50 to 64 years (4.8% vs 3.4%; P = .029). In fully adjusted models, the survivor-control difference in self-reported unmet MH needs persisted among young adults (24% relative increase; P = .023). Among cancer survivors, young adult survivors had the highest likelihood of reporting unmet MH needs. CONCLUSIONS: This nationally representative study found an increased perception of unmet needs for MH care among cancer survivors, particularly among young adult survivors, compared with the general population without cancer.

Concerns of Patients With Cancer on Accessing Cannabis Products in a State With Restrictive Medical Marijuana Laws: A Survey Study.

PURPOSE: Several states, particularly in the Southeast, have restrictive medical marijuana laws that permit qualified patients to use specific cannabis products. The majority of these states, however, do not provide avenues for accessing cannabis products such as in-state dispensaries. METHODS: We conducted a survey of patients registered for medical marijuana (low tetrahydrocannabinol [THC] oil cards) in an ambulatory palliative care practice in Georgia (one of the states with restrictive medical marijuana laws). RESULTS: We had a total of 101 responses. Among our sample of patients who use cannabis as part of a state-approved low THC oil program, 56% were male and 64% were older than age 50 years. Advanced cancer was the most common reason (76%) for granting the patients access to a low THC oil card. Although patients reported cannabis products as being extremely helpful for reducing pain, they expressed considerable concerns about the legality issues (64%) and ability to obtain THC (68%). Several respondents were using unapproved formulations of cannabis products. For 48% of the patients, their physician was the source of information regarding marijuana-related products. Furthermore, they believed that their health care providers and family members were supportive of their use of cannabis (62% and 79%, respectively). CONCLUSION: Patients on Georgia's medical marijuana program are most concerned about the legality of the product and their ability to obtain marijuana-related products. Therefore, we recommend that states with medical marijuana laws should provide safe and reliable access to cannabis products for qualifying patients.

Hypoxia-induced suppression of c-Myc by HIF-2α in human pulmonary endothelial cells attenuates TFAM expression.

The adaptive response to hypoxia is mediated in large part by stabilization of the hypoxia-inducible factors, HIF-1α and HIF-2α. A hallmark of this response is the metabolic shift to decreased oxidative phosphorylation and increased glycolysis. We hypothesized that hypoxic responses would include a suppression of mitochondrial gene expression. We determined the effects of hypoxia on TFAM, a key mitochondrial transcription factor, in normal pulmonary artery endothelial cells. Hypoxia decreased gene expression of TFAM and that of its upstream regulator, the transcriptional co-activator PGC1ß. Although HIF-1α and HIF-2α pathways both contributed to hypoxia-mediated PGC1ß suppression, TFAM suppression was regulated solely by HIF-2α-dependent mechanisms. We found that HIF-2α suppresses TFAM by decreasing c-Myc expression. In addition, we show a role for c-Jun in this pathway, linking HIF-2α with attenuation of c-Jun activation. Taken together, these findings establish a new link between HIF-2α and MAPK-signaling that mediates the adaptive regulation of mitochondrial gene expression under low oxygen tension.
