Differences in tumor size, clinical, demographic, and socioeconomic profiles of central nervous system tumors among a racially diverse cohort: A retrospective case-control study.

Background: One avenue to improve outcomes among brain tumor patients involves the mitigation of healthcare disparities. Investigating clinical differences among brain tumors across socioeconomic and demographic strata, such can aid in healthcare disparity identification and, by extension, outcome improvement.

Methods: Utilizing a racially diverse population from Hawaii, 323 cases of brain tumors (meningiomas, gliomas, schwannomas, pituitary adenomas, and metastases) were matched by age, sex, and race to 651 controls to investigate the associations between tumor type and various demographic, socioeconomic, and medical comorbidities.

Cancer-specific innate and adaptive immune rewiring drives resistance to PD-1 blockade in classic Hodgkin lymphoma.

Hodgkin Reed-Sternberg (HRS) cells of classic Hodgkin lymphoma (cHL), like many solid tumors, elicit ineffective immune responses. However, patients with cHL are highly responsive to PD-1 blockade, which largely depends on HRS cell-specific retention of MHC class II and implicates CD4 T cells and additional MHC class I-independent immune effectors. Here, we utilize single-cell RNA sequencing and spatial analysis to define shared circulating and microenvironmental features of the immune response to PD-1 blockade in cHL.

Key Components of Trauma-Informed Yoga Nidra.

Trauma exposure is universal to the human condition, with many affected individuals experiencing either posttraumatic stress disorder (PTSD) or subthreshold manifestations. Both scenarios can become functionally debilitating and collectively lay a heavy burden on individuals and society. Yoga nidra is one adjunctive treatment of growing interest, holding potential for its ability to alleviate symptoms of trauma, including hypervigilance, sleep disturbances, and disembodiment.

Diastereoselective Substitution Reactions of Acyclic Acetals Controlled by Remote Participation of an Acyloxy Group.

A remote carbonyl group up to six atoms away from the acetal group can induce 1,2-asymmetric induction in nucleophilic substitution reactions of acyclic acetals. Isolation of a cyclic carbonate under Lewis acidic conditions and computational studies suggested that the remote carbonyl group participated through the formation of a cyclic dioxocarbenium ion intermediate. The stereochemical outcomes depended on the size of the alkyl substituent and that of the nucleophile employed.

A Regional Analysis of Diversity, Equity, and Inclusion Initiatives in Plastic Surgery Residency Programs.

Background: Residents seek inclusive training environments that prioritize diversity. To evaluate programs that focus on these elements, websites have become essential for applicants but often lack in diversity, equity, and inclusion (DEI) content. Thus, this study aimed to assess current efforts and attention to DEI within plastic surgery residency programs and compare them by region.
