Abstract
BACKGROUND Incidence and treatment disparities for cutaneous melanomas have been documented among racial and sociodemographic minorities. However, the association between treatment types, race, and socioeconomic status remains unknown. OBJECTIVE To characterize treatment differences for head and neck melanoma in situ (MIS) and lentigo maligna (LM) based on race and sociodemographic variables. MATERIALS AND METHODS A population-based retrospective cohort study of the Surveillance Epidemiology and End Results database (1998-2016) was performed. Univariate and multivariate logistic regression modeling evaluated the association of race and US census-reported sociodemographic factors with Mohs micrographic surgery (MMS) utilization. RESULTS A total of 76,328 adult patients with head and neck MIS/LM were included. MMS accounted for 11.8% of total cases, with increased utilization observed since 1998-2002. Compared with areas with greater percentages of individuals completing high school (first quartile), patients living in the second (Odds ratio [OR] 0.71; 95% confidence interval [CI] 0.64-0.80; p < .001), third (OR 0.74; 95% CI 0.63-0.86; p < .001), and fourth quartiles (OR 0.44; 95% CI 0.35-0.55; p < .001) were less likely to undergo MMS for their MIS/LM. CONCLUSION Educational efforts and awareness can bridge the knowledge gaps of appropriate treatment in patients with head and neck MIS/LM.

Abstract
INTRODUCTION Cutaneous melanoma remains a leading cancer with sobering post-metastasis mortality rates. To date, the ligand-receptor interactome of melanomas remains weakly studied despite applicability to anti-cancer drug discovery. Here we leverage established crosstalk methodologies to characterize important ligand-receptor pairs in primary and metastatic cutaneous melanoma. METHODS Bulk transcriptomic data, representing 470 cutaneous melanoma samples, was retrieved from the Broad Genome Data Analysis Center Firehose portal. Tumor and stroma compartments were computationally derived as a function of tumor purity estimates. Identification of preferential ligand-receptor interactions was achieved by relative crosstalk scoring of 1380 previously established pairs. RESULTS Metastatic cutaneous melanoma uniquely enriched PTH2-PTH1R for tumor-to-stroma signaling. The Human R-spondin ligand family was involved in 4 of the 15 top-scoring stroma-to-tumor interactions. Receptor ACVR2B was involved in 3 of the 15 top-scoring tumor-to-tumor interactions. CONCLUSIONS Numerous gene-level differences in ligand-receptor crosstalk between primary and metastatic cutaneous melanomas. Further investigation of notable pairings is warranted.

Abstract
Description The COVID-19 pandemic magnified the existing inequities in the mental healthcare system that disproportionately affects communities of color, especially Latinx youth. This population faces disparities in the availability, accessibility, and quality of mental health services. This call to action to combat current mental health disparities entails ongoing collaborative efforts that address the plights of this community through community-based research studies. These studies inform efforts to mobilize health professionals, policymakers, and community partners across sectors to collaboratively dismantle systemic disparities and promote culturally-responsive initiatives.

Abstract
Histological evidence points to the presence of dopamine (DA) in the cephalic sensory organs of multiple gastropod molluscs, suggesting a possible sensory role for the neurotransmitter. We investigated the sensory function of DA in the nudipleuran Pleurobranchaea californica, in which the central neural correlates of sensation and foraging behavior have been well characterized. Tyrosine hydroxylase-like immunoreactivity (THli), a signature of the dopamine synthetic pathway, was similar to that found in two other opisthobranchs and two pulmonates previously studied: 1) relatively few (<100) THli neuronal somata were observed in the central ganglia, with those observed found in locations similar to those documented in the other snails but varying in number, and 2) the vast majority of THli somata were located in the peripheral nervous system, were associated with ciliated, putative primary sensory cells, and were highly concentrated in chemotactile sensory organs, giving rise to afferent axons projecting to the central nervous system. We extended these findings by observing that applying a selective D2/D3 receptor antagonist to the chemo- and mechanosensory oral veil-tentacle complex of behaving animals significantly delayed feeding behavior in response to an appetitive stimulus. A D1 blocker had no effect. Recordings of the two major cephalic sensory nerves, the tentacle and large oral veil nerves, in a deganglionated head preparation revealed a decrease of stimulus-evoked activity in the former nerve following application of the same D2/D3 antagonist. Broadly, our results implicate DA in sensation and engender speculation regarding the foraging-based decisions the neurotransmitter may serve in the nervous system of Pleurobranchaea and, by extension, other gastropods.

Abstract
WHAT IS KNOWN AND OBJECTIVE Pharmacogenomics holds promise in smoking cessation because of its potential to shed light on the complexity of drug metabolism and improve treatments using therapeutic agents. The cytochrome P450 2B6 gene (CYP2B6) encodes CYP2B6 enzyme that has been found to mediate the hydroxylation of bupropion, a smoking cessation aid. CYP2B6 exhibits a range of polymorphic variants that alter the pharmacokinetics and pharmacodynamics of bupropion. Genetic variations in CYP2B6 may influence the risk of adverse effects or efficacy of treatment with bupropion. The objective of this review was to investigate the influence of pharmacogenomics on smoking cessation therapy. METHODS A thorough literature search was conducted on PubMed, SCOPUS and EMBASE using keywords related to bupropion, smoking cessation, pharmacogenomics and CYP2B6. Research and review articles, case reports and clinical and preclinical studies pertinent to the research topic were identified, evaluated and summarized. Cited articles within the above-mentioned sources also provided pertinent information. RESULTS There is strong literature evidence to prove that CYP2B6 polymorphisms affect pharmacokinetic and pharmacodynamic properties of bupropion, thus affecting the therapeutic outcome of smoking cessation therapy. WHAT IS NEW AND CONCLUSIONS Complete understanding of pharmacogenetic variation of bupropion pharmacokinetics and pharmacodynamics will be beneficial for designing safer and more personalized smoking cessation therapy with improved outcomes.
