Photoaging, primarily caused by ultraviolet (UV) light, is the major factor in extrinsic skin aging. Existing anti-photoaging strategies mainly focus on early sun protection or repairing damaged skin, lacking a comprehensive treatment strategy. Therefore, this study developed dressing that actively shields against UV radiation and repairs photoaged offering double protection. This utilized exosome-like nanovesicles derived from

Background and Purpose: Deep tiny flow voids (DTFVs) are a specific type of collaterals surrounding chronic steno-occlusive middle cerebral artery (MCA), which can be identified on high-resolution magnetic resonance imaging (HR-MRI). This study aimed to investigate the presence DTFVs in patients with acute MCA occlusion their relevance clinical outcomes. Methods: Using data from two multicenter cohort studies, we examined analyzed characteristics. Univariable multivariable logistic linear...

To evaluate the association of GGN repeat polymorphism androgen receptor (AR) with ovarian reserve and response in controlled stimulation (COS). This genetic study was conducted among a total 361 women aged ≤40 years basal FSH≤12 U/L undergoing GnRH-agonist long protocol for COS university-affiliated IVF center. AR gene analyzed Sanger sequencing. The primary endpoint number antral follicle counts (AFCs), secondary endpoints were days, dose gonadotropin (Gn) used, retrieved oocytes,...

Abstract NK-large granular lymphocytic leukemia (NK-LGLL) is a rare chronic lymphoproliferative disorder and displays heterogeneity that remains insufficiently defined. CD56 plays pivotal role in NK-cell maturation linked to cytotoxicity. However, whether might be associated with distinctive characteristics NK-LGLL has not been determined. Hence, this study aims explore potential associations between clinical biological features 47 patients NK-LGLL. Above all, anemia (57.4%) was the most...

Abstract Context Immune checkpoint inhibitor (ICI)-related hypothyroidism is mostly irreversible and prompt thyroid hormone replacement therapy crucial, especially for patients undergoing neoadjuvant immunotherapy. Objective This study aimed to propose a novel titration strategy ICI-related hypothyroidism, evaluate levothyroxine (LT4) dose differences between patterns, develop predictive equation the optimal LT4 dose. Design Retrospective study. Setting Tertiary academic hospital. Patients...

Lung cancer, a malignant neoplasm that is globally prevalent and characterized by high incidence mortality rates, has seen the rise of immune checkpoint inhibitors (ICIs) as crucial systemic treatment. However, subset patients exhibits suboptimal responses to ICIs. Recently, studies revealed role vitamin D in inflammation modulation, cell differentiation, cancer prevention. Vitamin precisely modulates inflammatory states within tumor microenvironment (TME) targeting both innate adaptive...

Immune-related adverse events (irAEs) of immunotherapy would lead to the temporary or permanent discontinuation immune checkpoint inhibitors (ICIs). Among them, inhibitor pneumonitis (CIP) is a potentially life-threatening irAE. This study aimed identify differences between patients with low-grade CIPs (grades 1–2) and high-grade 3–5) explore prognostic factors. We retrospectively reviewed medical records 916 lung cancer who were treated ICIs. Patients identified after multidisciplinary...

Background and objectives: Atypical thymic carcinoids (ATCs) are rare mediastinal malignancies that lack established treatment guidelines. Capecitabine temozolomide (CapTem) has demonstrated significant efficacy in pancreatic neuroendocrine neoplasms (NENs), while its applicability effectiveness ATCs remain underexplored. This study seeks to investigate the efficacy, safety, prognostic factors associated with CapTem ATC patients. Design methods: Thirty-eight patients treated at our center...

e14683 Background: Checkpoint inhibitor pneumonitis (CIP) is a relatively uncommon but potentially life-threatening immune-related adverse event (irAE). Lung biopsies have not been commonly performed for CIP patients. Bronchoalveolar lavage fluid (BALF) analysis useful diagnostic approach interstitial lung disease. However, BALF features were inconsistent across different studies. Methods: We retrospectively reviewed the medical records of 154 patients with pathologically confirmed...
