Abstract

Background: The anatomic layers of the skin are well-defined, and a functional model of the skin barrier has recently been described. Barrier disruption plays a key role in several skin conditions, and moisturization is recommended as an initial treatment in conditions such as atopic dermatitis. This review aimed to analyze the skin barrier in the context of the function model, with a focus on the mechanisms by which moisturizers support each of the functional layers of the skin barrier to promote homeostasis and repair. Summary: The skin barrier is comprised of four interdependent layers – physical, chemical, microbiologic, and immunologic – which maintain barrier structure and function. Moisturizers target disruption affecting each of these four layers through several mechanisms and were shown to improve transepidermal water loss in several studies. Occlusives, humectants, and emollients occlude the surface of the stratum corneum (SC), draw water from the dermis into the epidermis, and assimilate into the SC, re- spectively, in order to strengthen the physical skin barrier. Acidic moisturizers bolster the chemical skin barrier by sup-porting optimal enzymatic function, increasing ceramide production, and facilitating ideal conditions for commensal microorganisms. Regular moisturization may strengthen the immunologic skin barrier by reducing permeability and subsequent allergen penetration and sensitization. Key Messages: The physical, chemical, microbiologic, and im-munologic layers of the skin barrier are each uniquely impacted in states of skin barrier disruption. Moisturizers target each of the layers of the skin barrier to maintain homeostasis and facilitate repair.

Abstract

Background Despite advances in therapeutic strategies a significant proportion of acute coronary syndrome (ACS) patients experience early coronary artery disease (CAD) progression, particularly those with diabetes.

Aim To evaluate CAD progression in diabetic patients treated with glucagon-like peptide 1 receptor agonists (GLP-1Ra) over 1 year after an ACS.

Methods Patients presenting with non–ST-elevation ACS between 2019 and 2022 were enrolled in a prospective registry and underwent serial coronary computed tomography angiography (CCTA) at baseline (after revascularization, during the index hospitalization) and at 1-year follow-up. The primary endpoint was the absolute change (1 year – baseline) in non-culprit lesion plaque burden (ΔPB) on CCTA, with the absolute change in patient percent atheroma volume (ΔPAV) as a key secondary endpoint. A comprehensive lipidomic, metabolomic, and proteomic plasma assessment was also performed in all GLP-1Ra–treated patients and four randomly selected controls.

Results Of 28 diabetic patients, 7 (25%) with 22 coronary plaques were treated with GLP-1Ra, and 21 (75%) with 65 plaques received other antidiabetic agents. In the 1-year observation frame, both ΔPB (-5.8±12.8% vs. -1.1±13.6%, p=0.041) and ΔPAV (-6.1% [-7.3, -1.8] vs. -0.7% [-2.4, 9.8], p=0.039) were significantly lower in GLP-1Ra-treated patients. Total atheroma volume also showed a numerically greater reduction in the GLP-1Ra cohort (0.7 mm³ [-2.5-8.7] vs. 25.0 mm³ [4.8–39.7]), primarily due to a decrease in plaque fibrofatty volume percentage (-2.9±10.1% vs. 1.0±6.8%, p=0.042). Lipi-domic, metabolomic, and proteomic analyses identified reductions in monoacylglycerols and triacylglycerols, increases in diacylglycerols and phosphatidylethanolamine, a shift from carbohydrate metabolism toward lipid metabolism and hormone regulation, and differential expression of proteins involved in complement activation, endothelial function, and cytoskeletal organization in GLP-1Ra–treated patients compared with controls.

Conclusions In diabetic patients with ACS, GLP-1Ra therapy was associated with a significant regression in coronary plaque burden at 1 year, supported by favorable lipidomic, metabolomic, and proteomic changes. These findings suggest a potential role for GLP-1Ra in modifying atherosclerosis progression beyond glycemic control.

Abstract

Aims Neonatal diabetes mellitus (NDM) occurs before 6–12 months of age and is commonly caused by activating mutations in KCNJ11 (KCNJ11-NDM) or ABCC8. Because of brain expression of these mutant ATP-dependent potassium channels, a spectrum of divergent neurodevelopmental difficulties have been described, including developmental delay, epilepsy, and neonatal diabetes (DEND). However, information on anxiety, social responsiveness, and grit is limited.

Methods Individuals with KCNJ11-NDM (N= 12) and their unaffected siblings (N=12) were recruited through the Uni-versity of Chicago Monogenic Diabetes Registry and participants or their parent/caregiver completedthe Screen for Adult/ Child Anxiety Related Disorder (SCAARED/SCARED), the Social Responsiveness Scale, Second Edition (SRS-2), and the Grit Scale.

Results Mean SRS-2 scores were significantly different between KCNJ11-NDM and sibling controls (P= <0.001 ), with 7/10 affected participants, and 0 /11 siblings, having scores suggestive of autism spectrum disorder (ASD). Differences in anxiety (P=0.69) and grit (P=0.46) were not significant when compared to sibling controls; however, 58% (7/12) of KCNJ11-NDM participants and 40% (4/10) of sibling controls had scores indicating an anxiety disorder by either self- or parent-report.

Conclusions Our results agree with previous studies suggesting significant difficulties with social functioning in KCNJ11- NDM, with 7/10 participants having scores suggestive of ASD, strongly reinforcing the need for early neurodevelopmental screening to allow for prompt support. Our report adds to the knowledge of this population in finding robust grit scores but with a high level of anxiety in both KCNJ11-NDM and unaffected siblings. Although families affected by KCNJ11-NDM may have a high risk of anxiety disorders, it is encouraging that affected and unaffected children exhibit robust self-resiliency that will help support functioning through the challenges of life. Study of additional individuals will help to clarify specific challenges, long-term outcomes, and best approaches for monitoring and support.
