Abstract
Immunoglobulin E (IgE)-mediated food allergy is a rapidly growing public health problem. The interaction between allergens and IgE is at the core of the allergic response. One of the best ways to understand this interaction is through structural characterization. This review focuses on animal-derived food allergens, overviews allergen structures determined by X-ray crystallography, presents an update on IgE conformational epitopes, and explores the structural features of these epitopes. The structural determinants of allergenicity and cross-reactivity are also discussed. Animal-derived food allergens are classified into limited protein families according to structural features, with the calcium-binding protein and actin-binding protein families dominating. Progress in epitope characterization has provided useful information on the structural properties of the IgE recognition region. The data reveals that epitopes are located in relatively protruding areas with negative surface electrostatic potential. Ligand binding and disulfide bonds are two intrinsic characteristics that influence protein structure and impact allergenicity. Shared structures, local motifs, and shared epitopes are factors that lead to cross-reactivity. The structural properties of epitope regions and structural determinants of allergenicity and cross-reactivity may provide directions for the prevention, diagnosis, and treatment of food allergies. Experimentally determined structure, especially that of antigen-antibody complexes, remains limited, and the identification of epitopes continues to be a bottleneck in the study of animal-derived food allergens. A combination of traditional immunological techniques and emerging bioinformatics technology will revolutionize how protein interactions are characterized.

Abstract
With increasing life expectancy, the quest for skin rejuvenation has gained prominence among individuals of diverse age groups. The popularity of nutricosmetics, notably dietary supplements, has garnered significant attention in recent years. Many scientific investigations have amassed compelling evidence highlighting the positive impact of hydrolyzed collagen supplementation in mitigating the visible signs of skin aging. This study aims to know the powerful effect of hydrolyzed collagen on the skin. This research method is to conduct a systematic review followed by a meta-analysis of the clinical trial focusing on randomized, double-blind, and controlled trials that examined the oral consumption of hydrolyzed collagen and reported outcomes related to skin aging, wrinkles, moisture levels, elasticity, and firmness. The selected articles from CENTRAL, PubMed, Google Scholar, and ScienceDirect databases were published from 2017 to 2023. The subsequent meta-analysis, comprising 14 distinct studies and a collective cohort of 967 participants, revealed encouraging findings favoring hydrolyzed collagen supplementation. It consistently demonstrated substantial enhancements in skin moisture levels and elasticity compared to the placebo group, a trend robustly corroborated by subgroup analysis. These compelling findings underscore the effectiveness of a 12-week regimen of hydrolyzed collagen supplementation in revitalizing the skin by augmenting its hydration and elasticity.

Abstract
Fish collagen is one of the major allergens involved in fish allergies; however, it has not been well-established whether fish collagen can cause anaphylaxis among individuals with fish allergies, especially children. A 9-year-old girl experienced anaphylaxis after consuming 2 fruit-flavored gummy tablets. Contacting the manufacturing company revealed that fish-derived collagen was used in the gummy tablets, and an oral fish collagen challenge test confirmed that the anaphylaxis was induced by fish collagen. Immunoblot analysis showed a 120-kDa band in a sample of the fish collagen in the gummy tablets, and no reactive band of the pork gelatin was observed. Additionally, salmon collagen and other fish samples that provoked symptoms were detected as a 120-kDa band in the immunoblot analysis. The 120-kDa band was identified as fish collagen by mass spectrometry confirming that it was the causative antigen of our patient's allergy. This case study confirms that fish collagen can cause anaphylaxis in children with fish allergies. Physicians and allergic individuals need to be aware that processed foods may contain fish collagen to avoid allergic reactions.

Abstract
Skin, hair, and nail supplements, sometimes referred to as "beauty supplements" or "ingestible skin care," are a large and growing industry. These products may contain vitamins and minerals, sometimes in very high doses. They may also contain herbs, hormones, microbes, or animal derivatives such as fish oils and collagen powders. Dietary supplements are regulated as foods, not as drugs, by the US Food and Drug Administration (FDA). Therefore, manufacturers do not need to provide any proof of safety, efficacy, or quality prior to sale. This is of serious concern, as many adverse effects due to supplement components have been reported. The potential risks cover multiple categories. These include acute toxicities, such as choking, as well as chronic toxicities, such as increased risk of diabetes. Teratogenicity and interactions with drugs and laboratory testing have been documented in research studies. Other risks include potentially increased risk of cancer with long-term use, allergic reactions, and others. It is vital that physicians educate their patients on these risks. As no post-marketing surveillance programs are required for supplements, our understanding of supplement risks is incomplete. Physicians should be wary of these risks and encourage further research and regulation.

Abstract
Background: Dietary supplements promoted for “skin, hair, and nail” health are becoming increasingly popular, although there is a lack of regulatory oversight. As no centralized database or repository for these supplements is available, the aim of this study was to provide an overview of supplements in a sample of retail stores, with a focus on safety concerns. Methods: Dermatology supplements were defined as those that featured the words “skin”, “hair”, “nails”, “beauty”, or “glow” in the product name or tagline. Seven stores including drug, grocery, department, and cosmetics stores were surveyed within a three-mile radius. Data were extracted from the Supplement Facts label of each product. Results: A total of 176 separate supplements were identified, containing a total of 255 distinct ingredients. These included vitamins, minerals, food extracts, botanicals, animal products (collagen, fish oils), amino acids, a hormone, and distinct microbial strains. Conclusion: This survey of “dermatology” supplements available in local retailers raised several safety concerns, including potential interactions, teratogenicity risks, a lack of independent third-party testing, lack of warning labels, and nutrient “overdosing”. Given limited regulation of dietary supplements, it is imperative that physicians educate patients on the potential risks. These include risks related to supplement ingredients and dosages, as well as risks related to the lack of regulatory oversight. Patients must also be educated about the multiple gaps in our knowledge of dietary supplements, especially in terms of efficacy and long-term safety.

Abstract
OBJECTIVE To assess the iatrogenic risks of gelatin allergy and identify resources for patient management. DATA SOURCES A literature review was performed using PubMed and public databases provided by the National Library of Medicine. STUDY SELECTIONS Reports of iatrogenic gelatin allergy associated with vaccines, hemostatic agents, intravenous colloids, medicinal capsules, and intraoperative surgical supplies. RESULTS Gelatin ingredients may not be identified by electronic medical record safeguards, and an exhaustive listing of potential iatrogenic exposures is elusive. The National Library of Medicine AccessGUDID (https://accessgudid.nlm.nih.gov/) can be a useful resource in evaluating medical devices for gelatin content. Unexpected sources of iatrogenic gelatin exposure include hemostatic agents, vascular grafts, intravascular cannulas, bone replacement implants, and emergency resuscitation fluids. CONCLUSION Vigilance is important within medical systems to avoid inadvertent gelatin exposure when caring for patients with gelatin allergy. Additional safeguards are needed to remove latent health care system errors that fail to prevent gelatin administration in this at-risk population.

Abstract
The current adverse event reporting system for dietary supplements lacks the ability to collect and analyze ongoing case reports in sufficient numbers to detect health issues. We conducted an online survey to collect data on skin manifestations due to supplement use in consumers and to identify the suspected products and ingredients. An online survey was conducted among 63,737 dietary supplement users in 2016. Those who self-reported experiences of skin anthema or itching caused by supplement use and recognized a causal relationship as almost certain (0.8%) were invited to provide further details of symptoms and products. Most of the users experienced mild symptoms with "itching and/or rash of body part." After the onset of skin manifestations, 69.3% ceased supplement use, while 26.6% continued supplement use, including those who reduced the amount or frequency of use. Respondents who visited the hospital in response to symptoms accounted for 26.0%, while 53.3% did not seek treatment. The products used were identified in 155 of 300 eligible respondents. Although those products were composed of multiple ingredients, the accumulated data suggested that cutaneous symptoms were related to the following constituents: "Peptides or animal by-products" (31.0%), "Herbal/Botanical" (23.2%) and "Fats and lipid" (13.5%). Conducting an online survey to elicit information directly from consumers identified components of supplements that are involved in skin manifestations that could lead to serious damage, and may fill a void in the current adverse event reporting system.
