Selected Articles
1. Dose-dependent association of prenatal microplastic exposure with gestational diabetes Mellitus: A prospective cohort analysis.
Among 770 primiparous pregnant women, 289 developed gestational diabetes mellitus (GDM). High reported microplastic exposure was associated with increased GDM risk versus low exposure (OR 2.19, 95% CI 1.46–3.28; p<0.001), with particularly strong associations for makeup and personal-care products.
Impact: This study identifies a potentially modifiable environmental exposure associated with a common pregnancy complication and specifically implicates cosmetic and personal-care products. Its prospective design and validated exposure questionnaire provide a useful foundation for exposure-measurement and causal research.
Clinical Implications: Clinicians may consider discussing reduction of avoidable cosmetic and personal-care product exposures with pregnant patients, but the findings do not yet justify formal exposure restrictions because exposure was self-reported and causality was not established.
Key Findings
- The prospective cohort included 770 primiparous pregnant women, of whom 289 (37.5%) developed GDM.
- GDM prevalence was 55.9% in the high-exposure group versus 36.6% in the low-exposure group.
- High exposure was associated with GDM versus low exposure with OR 2.19 (95% CI 1.46–3.28; p<0.001), with the strongest product-level signals involving makeup and personal-care items.
Methodological Strengths
- Prospective cohort design with a relatively large sample for an exposure-questionnaire study.
- Questionnaire reliability and content validity were assessed; multivariable logistic regression quantified risk associations.
Limitations
- Microplastic exposure was assessed by questionnaire rather than by biomonitoring or direct chemical measurements.
- Residual confounding, recall bias, and the possibility of reverse or noncausal associations cannot be excluded.
Future Directions: Future studies should use longitudinal biomonitoring of specific polymers and additives, clarify dermal versus dietary exposure pathways, replicate findings in diverse populations, and test whether exposure reduction lowers GDM incidence.
BACKGROUND: This study aimed to elucidate the potential crosslink between microplastic exposure and the development of Gestational Diabetes Mellitus (GDM) in primiparous pregnant women. METHODS: Prospective cohort study, involved 770 pregnant women. Data on demographic factors and microplastic exposure assessed through a validated Microplastic Exposure Questionnaire (MEQ) were collected, focusing on exposure via cosmetics, toiletries, and food. Participants were categorized into low (≤ 113), moderate (114-142), and high (≥ 143) exposure groups based on quartile-derived thresholds (Q1 = 113, Q3 = 142). Content Validity index and Cronbach's alpha reliability test were performed to ensure the reliability and validity of the questionnaire. Primary outcome assessed for the incidence of GDM. RESULTS: The Cronbach's alpha value was 0.835, indicating good internal consistency.
2. Antimicrobial-impregnated Sutures Reduce Surgical Site Infections in Plastic Surgery: A Systematic Review and Meta-analysis.
This PRISMA 2020 systematic review and meta-analysis included seven comparative studies involving 1,553 patients. Antimicrobial-impregnated sutures were associated with a significant reduction in surgical-site infections (RR 0.68, 95% CI 0.51–0.90) and improved postoperative outcomes, including cosmetic results.
Impact: The study addresses a common, preventable complication in plastic surgery and provides a quantitative estimate of benefit across available comparative evidence. It is directly relevant to perioperative practice while appropriately identifying the need for randomized trials.
Clinical Implications: Antimicrobial-impregnated sutures may be considered as part of surgical-site infection prevention in selected plastic-surgery procedures, particularly where infection consequences are substantial; local antimicrobial stewardship, cost, resistance, and anatomical context should be considered.
Key Findings
- Seven comparative studies comprising 1,553 patients were included, with 807 receiving antimicrobial-impregnated sutures and 746 serving as controls.
- Antimicrobial-impregnated sutures were associated with lower SSI risk: RR 0.68 (95% CI 0.51–0.90).
- The review reported improved postoperative outcomes, including cosmetic results, but called for randomized controlled trials to establish definitive guidance.
Methodological Strengths
- Systematic-review methodology followed PRISMA 2020, with database searching and random-effects pooling.
- The analysis included a clinically meaningful pooled sample and reported effect estimates with 95% confidence intervals.
Limitations
- Only seven comparative studies were identified, and the available evidence may include nonrandomized designs and heterogeneity in procedures and anatomical sites.
- The abstract does not report detailed publication-bias, heterogeneity, or study-quality estimates, and causal certainty remains limited.
Future Directions: Future research should conduct adequately powered randomized controlled trials stratified by procedure and anatomical site, compare antimicrobial agents and suture materials, evaluate resistance and cost-effectiveness, and report patient-centered cosmetic outcomes consistently.
BACKGROUND: Surgical site infections (SSIs) are a common complication in plastic surgery, contributing to increased morbidity, prolonged recovery, and increased healthcare costs. Antimicrobial-impregnated sutures (AISs) have shown promise in reducing SSI rates across surgical disciplines. However, their efficacy in plastic surgery remains unclear. METHODS: This review followed PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-Analysis) 2020 guidelines. PubMed and Web of Science were searched for comparative studies assessing AIS use. Seven studies were identified. Data extracted included patient demographics, study variables, and postoperative outcomes. SSI rates were pooled using a random-effects model and reported as a risk ratio (RR) with 95% confidence intervals (CIs). Analyses of wound healing/outcomes were performed using Fisher exact tests. RESULTS: In a pool of 1553 patients (807 intervention, 746 control), AIS use was associated with a significant reduction in SSIs (RR 0.68, 95% CI [0.51-0.90],
3. Application of polydopamine coated silk fibroin methacryloyl hydrogel loaded with cell free fat extract in diabetic wound healing.
The investigators developed pSilMA@Ceffe, a polydopamine-coated, photocrosslinkable silk fibroin methacryloyl hydrogel designed to provide tissue adhesion and sustained release of cell-free fat extract. In vitro assays and full-thickness wounds in db/db mice showed enhanced cell proliferation, migration, angiogenesis, wound closure, and organized collagen deposition.
Impact: This study integrates sustained biologic delivery, wet-tissue adhesion, and three-dimensional printability into a single candidate therapy for chronic diabetic wounds. The combination is mechanistically coherent and translationally attractive, although clinical efficacy remains untested.
Clinical Implications: The platform could eventually support local treatment of refractory diabetic wounds by improving retention of regenerative factors and wound-bed interaction. Translation requires confirmation of safety, manufacturing reproducibility, dosing, degradation products, infection performance, and benefit in large-animal and human studies.
Key Findings
- pSilMA@Ceffe demonstrated stable tissue adhesion, three-dimensional printability, and constant long-term release of cell-free fat extract.
- In vitro, the hydrogel supported cell survival and enhanced proliferation, migration, and angiogenic activity.
- In db/db mice with full-thickness skin wounds, treatment accelerated wound healing and neovascularization and promoted more organized collagen deposition.
Methodological Strengths
- The study combined physicochemical characterization, release kinetics, cellular assays, and an in vivo diabetic wound model.
- Histological and immunofluorescence assessments evaluated vascularization, proliferation, epithelial markers, and type I collagen remodeling.
Limitations
- The evidence is preclinical and relies on in vitro assays and db/db mice; human safety and efficacy were not assessed.
- The abstract does not provide detailed sample sizes, quantitative effect estimates, long-term outcomes, or comparisons with established wound treatments.
Future Directions: Future work should define the active components and release kinetics of the fat extract, compare the platform with standard wound care and approved advanced therapies, assess infection and immunologic responses, establish scalable manufacturing, and conduct large-animal followed by early-phase clinical studies.
Diabetic foot ulcers (DFUs) are common and serious problems in diabetes patients. They also represent one of the leading causes of non-traumatic lower limb amputation worldwide. Despite improvements in clinical care, numerous standard therapies fail to completely close chronic diabetic wounds. Cell-free fat extract (Ceffe) aids tissue repair and angiogenesis but its clinical worth is greatly reduced by rapid diffusion and enzymatic degradation in the wound. Silk fibroin methacryloyl (SilMA) can be formulated into a photocrosslinked hydrogel capable of sustained delivery of bioactive factors, whereas polydopamine (pDA) provides durable wet-tissue adhesion. In this work, we developed a multifunctional composite hydrogel pSilMA@Ceffe (polydopamine-coated SilMA hydrogel loaded with Ceffe) that integrates the prolonged release properties of SilMA with the tissue-binding strength of pDA to enhance healing of refractory diabetic wounds.
