Atopic dermatitis (AD) is a prevalent inflammatory skin condition that, depending on its severity, can cause enormous morbidity. Corticosteroids and systemic immunosuppression, traditionally standard of care for difficult-to-treat disease, have many undesirable side effects. The desire for targeted treatments along with an improved understanding of the pathophysiology of AD has spurred the development of novel treatments. In this article, we review promising new treatments and discuss how their targets-IL-13, IL-31, OX40 (CD134), and the Janus kinase family of proteins-participate in the pathogenesis of AD. We review the published phase II and III data for dupilumab, tralokinumab, lebrikizumab, nemolizumab, anti-OX40 antibody, baricitinib, abrocitinib, and upadacitinib. The introduction of new agents may offer new options, but it remains to be seen how narrow-acting agents, like single interleukin inhibitors, will compare in safety and efficacy to broad-acting agents such as JAK inhibitors. Key Points Our better understanding of the pathophysiology of AD has resulted in an explosion of research into new immunotherapies for this patient population. Multiple new agents targeting IL-13, IL-31, OX40 (CD134), and Janus kinase proteins may be effective for AD.

ObjectiveWe aimed at evaluating the ability of individuals without ophthalmologic training to quickly capture high-quality images of the cornea by using a smartphone and low-cost anterior segment imaging adapter (the “EyeGo” prototype).MethodsSeven volunteers photographed 1,502 anterior segments from 751 high school students in Varni, India, by using an iPhone 5S with an attached EyeGo adapter. Primary outcome measures were median photograph quality of the cornea and anterior segment of the eye (validated Fundus Photography vs Ophthalmoscopy Trial Outcomes in the Emergency Department [FOTO-ED] study; 1–5 scale; 5, best) and the time required to take each photograph. Volunteers were surveyed on their familiarity with using a smartphone (1–5 scale; 5, very comfortable) and comfort in assessing problems with the eye (1–5 scale; 5, very comfortable). Binomial logistic regression was performed using image quality (low quality: <4; high quality: ≥4) as the dependent variable and age, comfort using a smartphone, and comfort in assessing problems with the eye as independent variables.ResultsSix of the seven volunteers captured high-quality (median ≥4/5) images with a median time of ≤25 seconds per eye for all the eyes screened. Four of the seven volunteers demonstrated significant reductions in time to acquire photographs (P1=0.01, P5=0.01, P6=0.01, and P7=0.01), and three of the seven volunteers demonstrated significant improvements in the quality of photographs between the first 100 and last 100 eyes screened (P1<0.001, P2<0.001, and P6<0.01). Self-reported comfort using a smartphone (odds ratio [OR] =1.25; 95% CI =1.13 to 1.39) and self-reported comfort diagnosing eye conditions (OR =1.17; 95% CI =1.07 to 1.29) were significantly associated with an ability to take a high-quality image (≥4/5). There was a nonsignificant association between younger age and ability to take a high-quality image.ConclusionIndividuals without ophthalmic training were able to quickly capture a high-quality magnified view of the anterior segment of the eye by using a smartphone with an attached imaging adapter.

The amygdala is one of the most widely connected structures in the primate brain and plays a key role in social and emotional behavior. Here, we present the first genome- wide association study (GWAS) of whole-brain resting-state amygdala networks to discern whether connectivity in these networks could serve as an endophenotype for social behavior. Leveraging published resting-state amygdala networks as a priori endophenotypes in a GWAS meta-analysis of two adolescent cohorts, we identified a common polymorphism on chr.8p23.2 (rs10105357 A/G, MAF (G)=0.35) associated with stronger connectivity in the medial amygdala network (beta=0.20, p=2.97x10-8). This network contains regions that support reward processes and affiliative behavior. People carrying two copies of the minor allele for rs10105357 participate in more prosocial behaviors (t=2.644, p=0.008) and have higher CSMD1 expression in the temporal cortex (t=3.281, p=0.002) than people with one or no copy of the allele. In post-mortem brains across the lifespan, we found that CSMD1 expression is relatively high in the amygdala (2.79 fold higher than white matter, p=1.80x10-29), particularly so for nuclei in the medial amygdala, reaching a maximum in later stages of development. Amygdala network endophenotyping has the potential to accelerate genetic discovery in disorders of social function, such as autism, in which CSMD1 may serve as a diagnostic and therapeutic target.

Background: Resident cosmetic clinics (RCCs) are the training modality of choice among both residents and faculty and are a mainstay at most residency programs. 1 – 4 Despite this, knowledge of RCCs among plastic surgery consumers remains untested. We hypothesize that the public would be aware of and receptive to RCCs. Methods: Participants with prior cosmetic procedures or interest in future cosmetic procedures were recruited using Amazon Mechanical Turk and asked to complete a survey in September 2020. First, prior awareness of RCCs was assessed. After a brief description of RCCs, perceptions of safety and preferences for care were assessed. Results: After screening for quality, 815 responses were included. Forty-five percent of consumers were aware of RCCs. Seventy-six percent of consumers believed that RCCs were just as safe as attending clinics and 65% were comfortable receiving care from fourth-year residents or higher. Belief in RCC safety was associated with 4.8 times higher odds of feeling comfortable receiving care at an RCC [95% confidence interval (3.3–7.1), P < 0.001]. When given a hypothetical choice between residents and attendings in two scenarios, 46% of consumers chose residents for abdominoplasty and 60% chose residents for Botox injections. Belief in RCC safety was associated with choosing a resident or being indifferent in both scenarios. Conclusions: Consumer preference regarding RCCs has largely been untested. This study shows that belief in RCC safety influences consumers’ perceived comfort with receiving care at an RCC. This knowledge can help guide RCC practice and maximize learning opportunities for surgeons-in-training.
