1. Herbal medicine-derived carbon quantum dots in thermosensitive hydrogel: A multifunctional therapeutic strategy for UVB-induced photodamage.
The study synthesized MQEF-derived carbon quantum dots (MQEF-CQDs), incorporated them into a thermosensitive hydrogel, and showed antioxidant, anti-inflammatory, anti-apoptotic, antimicrobial, and collagen-protective effects in vitro and in vivo against UVB-induced skin damage; the hydrogel improved epidermal reconstruction and reduced collagen degradation with no significant HaCaT cytotoxicity reported.
Impact: Introduces a novel, plant-derived nanomaterial formulation with multifunctional actions that directly targets multiple pathways of UVB photodamage and demonstrates in vivo efficacy—advances translational potential for topical photoprotective therapeutics.
Clinical Implications: Preclinical evidence supports further development toward topical therapeutics for photodamage and skin aging; however, clinical trials are required to confirm safety, dosing, and efficacy in humans before adoption into practice or cosmetic products.
Key Findings
- MQEF-CQDs exhibit superior antioxidant capacity compared with traditional herbal extracts and show no significant toxicity to HaCaT cells.
- Incorporation of MQEF-CQDs into a thermosensitive hydrogel produces a dressing with skin-appropriate thermal, pH and rheological properties and dual antimicrobial and restorative functions.
- Both in vitro and in vivo models demonstrated mitigation of UVB-induced photodamage via antioxidant, anti-inflammatory, anti-apoptotic mechanisms and inhibition of collagen degradation, with improved epidermal structure and collagen fiber restoration.
Methodological Strengths
- Comprehensive preclinical evaluation including in vitro cytocompatibility and multiple in vivo endpoints (histology, collagen assessment).
- Physicochemical characterization of CQDs and hydrogel formulation with demonstration of skin-appropriate rheological, thermal and pH properties.
Limitations
- Preclinical study—no human data; translational safety and efficacy remain untested in clinical populations.
- Long-term stability, skin penetration kinetics in human skin, and potential immunogenicity were not assessed.
Future Directions: Advance to GLP toxicology and human Phase I trials to assess safety and topical pharmacodynamics; investigate formulation scale-up, stability, and penetration enhancers; compare against standard sunscreens/repair agents in controlled clinical studies.
Overexposure to ultraviolet B (UVB) radiation induces oxidative stress, inflammation, and apoptosis, which accelerates collagen degradation and skin aging. Current strategies for managing photodamage mainly focus on sun protection and skin repair; however, comprehensive therapeutic approaches are urgently needed. Herbal medicine-derived materials have shown great promise in combating photodamage. Modified Qing'e Formula (MQEF) has demonstrated the ability to treat photodamage by restoring redox homeostasis and is considered an effective anti-photodamage herbal remedy. However, the traditional oral decoction limits its application in topical treatments. In this study, we synthesized novel multifunctional carbon quantum dots (CQDs) using MQEF as a precursor (MQEF-CQDs). These CQDs exhibit superior antioxidant capacity compared to traditional herbal extracts and show no significant toxicity to HaCaT cells, indicating good biocompatibility and potential for skin drug delivery. Furthermore, MQEF-CQDs were incorporated into a thermosensitive hydrogel to form a MQEF-CQDs-hydrogel (MQEF-CQDs-gel) dressing, which is better suited for external use. This hydrogel displays temperature, pH, and rheological properties that align with the skin's physiological environment, along with dual functions of antimicrobial and restorative actions. Both in vitro and in vivo experiments demonstrate that MQEF-CQDs and MQEF-CQDs-gel mitigate UVB-induced photodamage through antioxidant, anti-inflammatory, anti-apoptotic, and collagen degradation-inhibition pathways. Additionally, MQEF-CQDs-gel significantly reduces skin damage, promotes the reconstruction of the epidermal structure, and restores damaged collagen fibers. These findings indicate that MQEF-CQDs represent a promising pathway for the green and sustainable production of herbal-based medicines, with broad industrial applications and as a potent candidate for photodamage treatment.
2. Ethno-cultural risk of ante-natal lead exposure among South Asian women in the UK.
This cross-sectional antenatal study measured blood lead levels (BLL) in 98 South Asian and 38 Caucasian pregnant women in Leeds, UK, finding significantly higher BLL in South Asian women (p=0.0005). Within South Asian women, higher BLLs were associated with living in pre-1970 housing, pesticide use in home countries, purchasing fish from ethnic shops, and certain cosmetics-related behaviours; authors recommend updating lead-free lifestyle guidance targeted to minority groups.
Impact: Identifies actionable, culturally specific exposure sources (including cosmetics and ethnic foods) linked to maternal lead burden in a minority population, informing targeted public health interventions and policy.
Clinical Implications: Clinicians and public health practitioners should consider cultural practices when screening for lead exposure in pregnancy; targeted education, screening, and housing remediation may reduce fetal lead exposure and improve outcomes in high-risk groups.
Key Findings
- Pregnant South Asian women (n=98) had significantly higher ante-natal BLLs than Caucasian women (n=38) in Leeds, UK (p=0.0005).
- Within South Asian participants, living in homes built before 1970, using pesticides in home countries, and purchasing fish (including dried 'shutki') from ethnic shops were associated with higher BLLs.
- Authors recommend updating 'lead-free lifestyle' guidance and targeted policy measures for minority and hard-to-reach groups.
Methodological Strengths
- Objective measurement of BLLs using Inductively Coupled Plasma Mass-Spectrometry (ICP-MS).
- Inclusion of an ethnically diverse sample with questionnaire-based assessment of culturally relevant exposures and linkage to fetal birth outcomes.
Limitations
- Modest sample size and single-site (Leeds) limit generalizability to other regions and South Asian subgroups.
- Cross-sectional antenatal design limits causal inference; potential recall bias in questionnaire responses.
Future Directions: Larger multi-site studies across different UK regions and South Asian subpopulations to confirm findings, longitudinal maternal–infant cohorts to assess outcomes, and intervention trials (education, product regulation, housing remediation) to reduce exposure.
BACKGROUND: Maternal lead exposure, shaped by environmental and cultural factors, can transfer to the foetus. Culturally embedded practices among South Asian women, including dietary habits and traditional cosmetics, may increase exposure compared with Caucasian women. This study measured ante-natal blood lead levels in South Asian mothers in Leeds, UK, and examined associated environmental, ethno-cultural, lifestyle, and foetal outcome factors.
METHODS: Pregnant SA and Caucasian women were recruited from Leeds, UK. Participants donated ante-natal blood sample, and completed a lifestyle questionnaire. BLLs were analysed using Inductively Coupled Plasma Mass-Spectrometry. Foetal birth outcomes were recorded after delivery.
FINDINGS: A significant difference in BLL was observed between pregnant South Asian (n = 98) and Caucasian (n = 38) women living in the UK (t = 4.00, df = 134, p = 0.0005). For South Asian women alone, factors associated with raised BLLs were: living in a home built before 1970 (t = 2.558, df = 97, p = 0.012); using pesticides for gardening in SA (t = 2.880, p=0.005), purchasing fish (fresh or dried (shutki)) from ethnic shops (t = 3.494, p = 0.001), shopping for cosmetics (PC1
3. Acrylate Allergic Contact Dermatitis Among Manicure Consumers and Professionals.
This clinical/occupational review highlights increasing acrylate allergic contact dermatitis among nail consumers and professionals. Key points include variable risk across products, role of repeated exposure or improper curing in causing onycholysis and dermatitis, and that management focuses on strict acrylate avoidance, alternative nail methods, and nurse-led education and advocacy for often-marginalized nail technicians.
Impact: Draws attention to an under-recognized occupational and consumer health risk linked to cosmetic practice and provides actionable recommendations for frontline nurses to reduce exposure and support affected workers.
Clinical Implications: Clinicians and occupational health services should screen for acrylate exposure in patients with nail or periungual dermatitis, counsel on strict avoidance, recommend safer alternatives, and advocate for workplace protections and training for nail professionals.
Key Findings
- Acrylate allergic contact dermatitis is increasingly reported among both manicure consumers and professionals, with symptoms including onycholysis that can be painful and slow to heal.
- Risk varies by product and by exposure pattern; repeated exposure and improper curing increase risk.
- Management emphasizes strict acrylate avoidance, selection of alternative nail beautification methods, and nurse-led education and advocacy for nail professionals.
Methodological Strengths
- Practical synthesis relevant to frontline nursing and occupational health with clear action points.
- Emphasis on both consumer and professional exposures and social determinants affecting nail technicians.
Limitations
- Review/educational article without new quantitative primary data or systematic review methodology.
- May lack comprehensive risk estimates and does not provide standardized diagnostic or management protocols.
Future Directions: Epidemiologic surveillance to quantify incidence among workers, standardized diagnostic criteria and patch-testing protocols, workplace intervention trials (ventilation, PPE, curing protocols), and outreach programs led by nurses for marginalized nail professionals.
Acrylate allergic contact dermatitis is a growing concern, particularly among women exposed to nail cosmetics as consumers or professionals. Not all nail products carry equal risk. Repeated exposure to acrylates or improper curing can lead to symptoms resembling other forms of allergic contact dermatitis. Onycholysis is one common symptom that can be painful and slow to heal. Treatment of acrylate allergic contact dermatitis centers on acrylate avoidance and selection of alternative nail beautification methods. Nurses are positioned to educate and advocate for nail professionals, who are often marginalized and at heightened risk due to prolonged exposure and limited access to workplace protections. Nurses can also provide education on strict product avoidance, coach on nail care strategies, and provide emotional support.
