    Abstract Nicotinamide phosphoribosyltransferase (NAMPT) is crucial for nicotinamide adenine dinucleotide (NAD(+)) biosynthesis in mammalian cells. NAMPT inhibitors represent multifunctional anticancer agents that act on NAD(+) metabolism to shut down glycolysis, nucleotide biosynthesis, and ATP generation and act indirectly as PARP and sirtuin inhibitors. The selectivity of NAMPT inhibitors preys on the increased metabolic requirements to replenish NAD(+) in cancer cells. Although initial clinical studies with NAMPT inhibitors did not achieve single-agent therapeutic levels before dose-limiting toxicities were reached, a new understanding of alternative rescue pathways and a biomarker that can be used to select patients provides new opportunities to widen the therapeutic window and achieve efficacious doses in the clinic. Recent work has also illustrated the potential for drug combination strategies to further enhance the therapeutic opportunities. This review summarizes recent discoveries in NAD(+)/NAMPT inhibitor biology in the context of exploiting this new knowledge to optimize the clinical outcomes for this promising new class of agents.

    Abstract Purpose: Low-grade intermediate-risk nonmuscle-invasive bladder cancer is a chronic illness commonly treated by repetitive transurethral resection of bladder tumor. We compared the efficacy and safety of intravesical chemoablation with UGN-102 (a reverse thermal gel containing mitomycin), with or without subsequent transurethral resection of bladder tumor, to transurethral resection of bladder tumor alone in patients with low-grade intermediate-risk nonmuscle-invasive bladder cancer.
    Materials and methods: This prospective, randomized, phase 3 trial recruited patients with new or recurrent low-grade intermediate-risk nonmuscle-invasive bladder cancer to receive initial treatment with either UGN-102 once weekly for 6 weeks or transurethral resection of bladder tumor. Patients were followed quarterly by endoscopy, cytology, and for-cause biopsy. The primary end point was disease-free survival. All patients were followed for adverse events.
    Results: Trial enrollment was halted by the sponsor to pursue an alternative development strategy after 282 of a planned 632 patients were randomized to UGN-102 ± subsequent transurethral resection of bladder tumor (n=142) or transurethral resection of bladder tumor monotherapy (n=140), rendering the trial underpowered to perform hypothesis testing. Patients were predominantly male and ≥65 years of age. Tumor-free complete response 3 months after initial treatment was achieved by 92 patients (65%) who received UGN-102 and 89 patients (64%) treated by transurethral resection of bladder tumor. The estimated probability of disease-free survival 15 months after randomization was 72% for UGN-102 ± transurethral resection of bladder tumor and 50% for transurethral resection of bladder tumor (hazard ratio 0.45). The most common adverse events (incidence ≥10%) in the UGN-102 group were dysuria, micturition urgency, nocturia, and pollakiuria.
    Conclusions: Primary, nonsurgical chemoablation with UGN-102 for the management of low-grade intermediate-risk nonmuscle-invasive bladder cancer offers a potential therapeutic alternative to immediate transurethral resection of bladder tumor monotherapy and warrants further investigation.

    Abstract Cancer cells undergo extensive genetic and epigenetic rewiring to support the malignant phenotype, and yet cell survival and proliferation often remain dependent on one or a limited number of driver mutations. This is the concept of oncogene addiction, the elucidation of which has led to substantial progress in therapeutic interventions. However, because resistance mechanisms often emerge, explicating the pathways that connect therapeutic oncogene inactivation to the cell death machinery is critical to exploiting additional synthetic lethal opportunities.

    Abstract Objective: To describe prostate-specific antigen (PSA) response and treatment adherence, overall and stratified by race, for patients with non-metastatic castration-resistant prostate cancer (nmCRPC) treated with apalutamide.
    Methods: Electronic medical records representing 63 urology practices from the United States were used to conduct this study. Patients with ≥2 apalutamide prescription fills and ≥12 months of prior prostate cancer management were identified. Patients were followed from apalutamide initiation until a switch to another antineoplastic treatment, death, or end of data availability (October 4, 2019). PSA response (≥50% decline from baseline PSA) and apalutamide adherence rates are described for the overall nmCRPC population treated and also stratified by race (Black and non-Black cohorts).
    Results: Overall, 193 patients with nmCRPC were initiated on apalutamide. Thirty-three patients were Black (17.1%), 138 were non-Black (71.5%), and the remaining had an unknown racial background. The mean baseline PSA level for the overall, Black, and non-Black cohorts, was 7.0 ng/mL, 10.5 ng/mL, and 5.6 ng/mL, respectively. At 12 months of follow-up, PSA response was 86.0%, 93.1%, and 85.9% for the overall, Black, and non-Black cohorts, respectively. During a mean follow-up period of 333 days, 352 days, and 326 days, adherence was 93.6%, 90.1%, and 94.5% for the overall, Black and non-Black cohorts, respectively.
    Conclusion: This real-world study of patients with nmCRPC initiated on apalutamide showed that PSA response was robust and consistent with clinical trial data. Moreover, both Black and non-Black patients demonstrated high treatment adherence.

    Abstract Objective: Recording in the operating room is an important tool to help surgical teams improve their performance. This is becoming more feasible using the Operating Room Black Box, a comprehensive data capture platform. Operating room (OR) staff, however, may voice reasonable concerns as recording initiatives are implemented. The objective of this study was to assess pre-implementation attitudes of OR staff toward operative recording and explore the relationship of these attitudes to the themes of (1) safety culture, (2) impostor syndrome, and (3) privacy concerns.
    Methods: This cross-sectional survey study measured staff members' beliefs and opinions of operative recording and used three previously validated tools (safety attitudes questionnaire, clance impostor phenomenon scale, and dispositional privacy concern) to assess personal and professional factors. Concepts were correlated using Pearson's correlation coefficient.
    Results: Forty-three staff members participated in this study, with a response rate of 45% (n = 43/96, 20/22 nurses, 9/11 gynecologists, 14/63 anesthesiologists). Opinions of operative data capture were generally positive (5-point Likert scale, mean = 3.81, SD = 0.91). Nurses tended to have more favorable opinions of the OR Black Box as compared to gynecologists and anesthesiologists, though this did not reach statistical significance (4.15 vs. 3.67 vs 3.43, p = 0.06). Impostor syndrome characteristics correlated with concerns about litigation related to recording (r =  - 0.32, p = 0.04).
    Conclusion: There are personal and professional attributes of the OR team that impact perceptions of the OR Black Box and implications around privacy and litigation. Addressing these concerns may facilitate successful implementation of the OR Black Box and improve team communication and patient safety in the OR.

    Abstract CISD2, an ER BCL2-associated autophagy regulator also known as NAF-1, is responsible for the human degenerative disorder Wolfram Syndrome 2. In order to interrogate the physiological role of CISD2 we generated and characterized the Cisd2 gene deletion in mice. Cisd2 null mice manifest significant degeneration in skeletal muscle tissues, which is accompanied with augmented autophagy, dysregulated Ca ( 2+) homeostasis and elongated mitochondria. Our findings describe a novel role for BCL2-CISD2 in the homeostatic maintenance of skeletal muscle. It remains to be elucidated how and if the antagonism of the BECN1 autophagy-initiating complex and modulation of ER Ca ( 2+) homeostasis by BCL2-CISD2 are interconnected.

    Abstract Accumulating evidence suggests that Mcl-1 plays a critical pro-survival role in the development and maintenance of both normal and malignant tissues. Regulation of Mcl-1 expression occurs at multiple levels, allowing for either the rapid induction or elimination of the protein in response to different cellular events. This suggests that Mcl-1 can play an early role in response to signals directing either cell survival or cell death. Deregulation of pathways regulating Mcl-1 that result in its over-expression likely contribute to a cell's inability to properly respond to death signals possibly leading to cell immortalization and tumorigenic conversion. Correspondingly, Mcl-1 has been shown to be up-regulated in numerous hematological and solid tumor malignancies. Moreover, this up-regulation appears to be a factor in the resistance of some cancer types to conventional cancer therapies. Mechanisms that abrogate the pro-survival function of Mcl-1 either by diminishing its levels or inactivating its functional BH3 groove have shown promise for the combinational treatment with existing cancer therapies and as single agents in certain malignancies. Here we review the various pathways that regulate Mcl-1 expression and describe agents that are currently under development to modulate Mcl-1 activity for therapeutic benefit in oncology.
