Preoperative gastric retention in endoscopic retrograde cholangiopancreatography patients: Assessing risks and optimizing outcomes.

This article is a comment on the article by Jia , aiming at establishing a predictive model to predict the occurrence of preoperative gastric retention in endoscopic retrograde cholangiopancreatography preparation. We share our perspectives on this predictive model. First, further differentiation in predicting the severity of gastric retention could enhance clinical outcomes.

Pathological-microenvironment responsive injectable GelMA hydrogel with visualized biodegradation for pressure-assisted treatment of hypertrophic scars.

Intralesional injection of 5-fluorouracil for the clinical treatment of hypertrophic scars (HS) remains challenging due to its short half-life, as well as the absence of evidence-based dosage and frequency injection guidelines. Herein, we developed a matrix metalloproteinases (MMPs)/reactive oxygen species (ROS)-responsive injectable prodrug hydrogel (GFP) that exhibits sustained drug release and fluorescence imaging capability, aiming to facilitate the optimization of injection dosage and frequency in HS treatment. The GFP hydrogel comprises gelatin methacryloyl and pendant methacryloyl-decorated tetrapeptide (PPPK) with 5-fluorouracil acetic acid/rhodamine B at the N-terminus.

Refining the targeted population and achieving better for colorectal cancer screening.

This editorial comments on the article entitled "Stage at diagnosis of colorectal cancer through diagnostic route: Who should be screened?" by Agatsuma , who conducted a retrospective study aiming at clarifying the stage at colorectal cancer (CRC) diagnosis based on different diagnostic routes. We share our opinion about CRC screening programs. The current situation suggests the need for a more specific and targeted population for CRC screening.

Identification and validation of CCR5 linking keloid with atopic dermatitis through comprehensive bioinformatics analysis and machine learning.

There is sufficient evidence indicating that keloid is strongly associated with atopic dermatitis (AD) across ethnic groups. However, the molecular mechanism underlying the association is not fully understood. The aim of this study is to discover the underlying mechanism of the association between keloid and AD by integrating comprehensive bioinformatics techniques and machine learning methods.

Endogenous stimuli-responsive separating microneedles to inhibit hypertrophic scar through remodeling the pathological microenvironment.

Hypertrophic scar (HS) considerably affects the appearance and causes tissue dysfunction in patients. The low bioavailability of 5-fluorouracil poses a challenge for HS treatment. Here we show a separating microneedle (MN) consisting of photo-crosslinked GelMA and 5-FuA-Pep-MA prodrug in response to high reactive oxygen species (ROS) levels and overexpression of matrix metalloproteinases (MMPs) in the HS pathological microenvironment.

Peeling from a liquid.

We establish the existence of a cusp in the curvature of a solid sheet at its contact with a liquid subphase. We study two configurations in floating sheets where the solid-vapor-liquid contact line is a straight line and a circle, respectively. In the former case, a rectangular sheet is lifted at its one edge, whereas in the latter a gas bubble is injected beneath a floating sheet.

Risk factors of long-term alopecia after pulsed-dye laser treatment for infantile scalp hemangiomas: A retrospective study.

Pulsed-dye laser (PDL), as an effective and frequently-used treatment modality for infantile hemangiomas (IH), could render patients at risk of developing long-term alopecia. Data on alopecia caused by PDL treatment remain scant and the contributing factors are not clear. Our objective was to identify the risk factors associated with long-term alopecia resulting from PDL treatment for scalp IH.

Comparing the Accuracy of ABCD-10 and SCORTEN in Predicting the In-Hospital Mortality of Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis: A Multi-Institutional Study from Central China.

Background: The newly described ABCD-10 (age, bicarbonate, cancer, dialysis, 10% body surface area [BSA]) is a 5-item mortality prediction model for patients with Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). It was developed in the United States, has at present been externally tested only in the United States, Spain, and Singapore, and remains to be validated in resource-restricted settings. We sought to compare the accuracy of ABCD-10 and Score of Toxic Epidermal Necrolysis (SCORTEN) in predicting in-hospital mortality in a cohort from central China.

Transparent photothermal hydrogels for wound visualization and accelerated healing.

Utilizing photothermal hydrogels as a wound dressing is a promising strategy to accelerate wound healing. Usually, a photothermal hydrogel has a strong light-absorbing capability, and hence its transparency can be largely sacrificed, which is unbeneficial for the visual monitoring of wound states. It remains challenging to balance the trade-off between the photothermal conversion and wound visualization for the photothermal hydrogel dressing.

Injectable and pH-Sensitive Hyaluronic Acid-Based Hydrogels with On-Demand Release of Antimicrobial Peptides for Infected Wound Healing.

Antibiotics' abuse in bacteria-infected wounds has threatened patients' lives and burdened medical systems. Hence, antibiotic-free hydrogel-based biomaterials, which exhibit biostability, on-demand release of antibacterial agents, and long-lasting antimicrobial activity, are highly desired for the treatment of chronic bacteria-infected wounds. Herein, we developed a hyaluronic acid ()-based composite hydrogel, with an antimicrobial peptide [, KK(SLKL)KK] as a cross-linking agent through Schiff's base formation, which exhibited an acidity-triggered release of (pathological environment in bacteria-infected wounds, pH ∼ 5.

Apoptotic cell-mimicking gold nanocages loaded with LXR agonist for attenuating the progression of murine systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) constitutes an autoimmune disease characterized by the breakdown of tolerance to self-antigens, sustained production of pathogenic autoantibodies, and damage to multiple organs and tissues. Nanoparticle (NP)-based therapeutics have demonstrated efficacy in attenuating the progression of SLE. However, investigations of nano-drugs that address the crucial initiating factor in the pathogenesis of SLE; e.

The Unknown Aspect of BAFF: Inducing IL-35 Production by a CD5CD1dFcγRIIb Regulatory B-Cell Subset in Lupus.

IL-35 is a critical immunosuppressive cytokine that plays an important role in various autoimmune diseases. The purpose of this study was to determine whether BAFF, a key pathogenic factor in systemic lupus erythematosus, also a dichotomous regulator for B-cell immune responses, has an effect on IL-35-producing regulatory B cells and their underlying mechanisms in lupus. We found that exogenous BAFF could induce IL-35 production by splenic B cells from MRL-Fas mice.
