RESUMEN

BACKGROUND: Although patients undergoing hematopoietic stem cell transplantation (HSCT) must cope with psychological distress and isolation during an extended transplant hospitalization, psychosocial interventions to address these unmet needs are lacking. Virtual reality offers an innovative modality to deliver a patient-centered psychosocial intervention to address psychosocial needs of patients undergoing HSCT. However, there are currently no supportive care interventions leveraging virtual reality in patients undergoing HSCT. OBJECTIVE: To describe the methods of a randomized clinical trial (RCT) to assess the feasibility and preliminary efficacy of a self-administered, virtual reality-delivered psychosocial intervention (BMT-VR) to improve psychological distress and quality of life (QOL) for patients hospitalized for HSCT. METHODS: This study entails a single-center RCT of BMT-VR compared to usual transplant care in 80 patients hospitalized for HSCT. Adult patients with hematologic malignancies hospitalized for autologous or allogeneic HSCT are eligible. BMT-VR includes psychoeducation about the HSCT process, psychosocial skill building to promote effective coping and acceptance, and self-care and positive psychology skills to promote post-HSCT recovery. The primary aim is to assess the feasibility defined a priori as ≥60% of eligible patients enrolling in the study, and of those enrolled and randomized to the BMT-VR, ≥ 60% completing 4/6 BMT-VR modules. Secondary objectives include assessing the preliminary effects on psychological distress and QOL. DISCUSSION: This is the first RCT of a virtual reality-delivered psychosocial intervention for the HSCT population. If deemed feasible, a future larger multi-site clinical trial can evaluate the efficacy of BMT-VR on outcomes for patients hospitalized for HSCT.

RESUMEN

Caregivers of patients undergoing chimeric antigen receptor T cell therapy (CAR-T) play a critical role during treatment, yet their experience remains largely unaddressed. We aimed to longitudinally describe quality of life (QoL) and psychological distress, as well as prognostic awareness, in caregivers and explore the association of prognosis awareness with baseline psychological distress. We conducted a longitudinal study of caregivers of patients undergoing CAR-T and examined QoL (CAReGiverOncology QoL questionnaire) and psychological distress (Hospital Anxiety and Depression Scale) prior to CAR-T (baseline) and at days 7, 30, 90, and 180 post-CAR-T. At baseline, caregivers and patients completed the Prognostic Awareness Impact Scale, which examines cognitive understanding of prognosis, emotional coping with prognosis, and adaptive response (ie, capacity to use prognostic awareness to inform life decisions). We enrolled 58% (69 of 120) of eligible caregivers. Caregivers reported QoL impairments that did not change over time (B = 0.09; P = .452). The rates of clinically significant depression and anxiety symptoms were 47.7% and 20.0%, respectively, at baseline, and 39.1% and 17.4% at 180 days. One-third (32%) of the caregivers and patients reported that their oncologist said the cancer is curable. Caregivers' greater emotional coping with prognosis was associated with fewer symptoms of anxiety (B = -.17; P < .001) and depression (B = -.02; P < .001). Cognitive understanding of prognosis and adaptive response were not associated with psychological distress. Caregivers reported QoL impairments throughout the study period. A substantial proportion of caregivers experienced psychological distress and reported misperceptions about the prognosis, highlighting the need for supportive care interventions.

RESUMEN

Potassium trifluoroborates have gained significant utility as coupling partners in organic synthesis, particularly in the Suzuki-Miyaura coupling reaction. Recently, they have also been used as radical precursors under oxidative conditions to generate carbon-centered radicals. These versatile reagents have found new applications in photoredox catalysis, including radical substitution, conjugate addition reactions, and transition metal dual catalysis. In addition, this photomediated redox neutral process has enabled radical-radical coupling with persistent radicals in the absence of a metal, and this process remains to be fully explored. In this study, we report the radical-radical coupling of benzylic potassium trifluoroborate salts with isolated acyl azolium triflates, which are persistent radical precursors. The reaction is catalyzed by an organic photocatalyst and forms isolable tertiary alcohol species. These compounds can be transformed into a range of substituted ketone products by simple treatment with a mild base.

RESUMEN

A mild photocatalyzed approach to achieve the α-alkylation of esters via formation of an α -radical is disclosed here. Cesium enolates of esters were generated in situ using Cs2CO3 as a base. A subsequent photocatalyzed oxidation at the α-carbon of these enolates produced an α-radical that was added into activated alkenes. This is the first example accessing the α-carbon radical of esters in photoredox catalyed transformations.

RESUMEN

The rapid synthesis of cyclic scaffolds is of high importance to the chemistry community. Strategies for the convergent synthesis of substituted carbocycles and heterocycles remain underexplored despite the plethora of applications that these cyclic motifs have in the pharmaceutical and materials industries. Reported herein is a tandem carbene and photoredox-catalyzed process for the convergent synthesis of substituted cycloalkanones via a formal [5 + 1] cycloaddition. Featuring two distinct photoredox cycles and a novel α-oxidation of benzylic ketones, this reaction offers a mild approach to construct two contiguous C-C bonds and eliminates the need for strong bases or expensive metal catalysts. The utility of this method is highlighted through various product diversification reactions that allow access to a range of important cyclic scaffolds.
