Rationale: Thyroglossal duct carcinoma, a rare clinical condition characterized by ectopic thyroid adenocarcinoma within thyroglossal duct cysts (TGDCs), typically confirmed through intraoperative rapid pathology, this condition generally has a favorable prognosis. Nevertheless, comprehensive treatment guidelines across all disease stages are lacking, the purpose of this study is to report 1 case of the disease and propose the treatment plan for each stage of the disease. Patient concerns: A patient presented with thyroid swelling, classified as C-TIRADS 4A following a physical examination. Preoperative thyroid puncture identified papillary thyroid carcinoma, and genetic testing revealed a BRAF gene exon 15-point mutation. Ancillary tests showed a slightly decreased thyroid stimulating hormone (TSH) level (0.172) with no other significant abnormalities. Diagnoses: Preoperative fine-needle aspiration cytology (FNAC) confirmed right-side thyroid cancer. Intraoperative exploration uncovered a TGDC and intraoperative rapid pathology confirmed thyroglossal duct carcinoma. Interventions: A Sistrunk operation and ipsilateral thyroidectomy were performed. Outcomes: Postoperative recovery was satisfactory. Lessons: Thyroglossal duct carcinoma is a rare disease affecting the neck. Due to limited clinical cases and the favorable prognosis associated with this condition, there is currently no established set of diagnostic and treatment guidelines. According to tumor size, lymph node metastasis, thyroid status and other factors, the corresponding treatment methods were established for each stage of thyroglossal duct cancer, which laid the foundation for the subsequent treatment development of this disease.

The skin’s integrity is vulnerable to external elements that can induce injuries, leading to wound formation. It’s crucial to comprehend wound healing processes to protect the body when this protective barrier is compromised. Over the last 2 decades, there has been considerable progress in understanding delayed wound healing, with a focus on the mechanisms and microenvironmental factors involved. The connection between oxidative stress and wound healing has recently gained attention, emphasizing the need for in-depth analysis to propel further advancements and interventions in this area. Despite these advancements, there remains a noticeable void in the literature concerning the application of scientometric methods to systematically examine the progression of wound healing research. Additionally, a comprehensive assessment of the research output and effectiveness of various researchers and institutions in this field is lacking. To address these gaps, we analyzed data from the Web of Science Core Collection from January 1, 2000, to December 31, 2023, utilizing relevant keywords. Using CiteSpace, we created visual maps that depict the evolution and structure of keyword clusters, and both CiteSpace and VOSviewer were used to evaluate the performance of research networks across different countries, institutions, and authors. This data was methodically analyzed. The leading institution in this field is the Chinese Academy of Medical Sciences. The key researchers are Bekeschus, Sander; Li, Yang; Bi, Yang; Fan, Daidi; and Zhang, Yu. Our software analysis reviewed 3025 studies, revealing 19 co-citation clusters that highlight current trends in research on oxidative stress and wound healing. Prominent journals, leading institutions, and key researchers were identified. Key emerging research directions include studying the mechanisms linking oxidative stress to wound healing, exploring the use of antioxidant substances in wound dressings, and investigating how nanomaterials in dressings can influence oxidative stress. These focal points emphasize the significance of understanding oxidative stress’s impact on wound healing and investigating new methods to enhance therapeutic efficacy. This comprehensive approach not only fills a gap in the current literature but also sets the stage for future research endeavors in this crucial area of health science.

Purpose: To assess the diagnostic performance of various imaging modalities in detecting and monitoring prostate cancer across different disease stages using diagnostic test accuracy (DTA) and network meta-analysis (NMA). Methods: A systematic literature review was conducted to identify studies evaluating mpMRI, PSMA PET/CT, MRE, MRSI, BS, CT, PET, and other tracers for prostate cancer detection. Data on sensitivity, specificity, PPV, NPV, and detection rate were extracted and analyzed using NMA. Result: Across 123 studies involving 9,371 patients, 68Ga-P16-093 PET/CT and 68Ga-PSMA-617 PET/CT showed high diagnostic accuracy in early-phase prostate cancer. For lymph node metastasis, 68Ga-PSMA-11 PET/MRI was the most sensitive. 18F-DCFPyL PET/CT had the highest specificity and PPV, while 18F-PSMA-1007 PET/CT had the highest NPV. In bone metastasis, 18F-PSMA-1007 PET/MRI excelled in sensitivity and NPV, while 18F-Fluciclovine PET/CT had the highest specificity and PPV. For biochemical recurrence, 18F-PSMA-1007 PET/CT had the highest lesion detection rate, and for different radiotracers, 18F-PSMA-1007 had the highest detection rate. Conclusion: This network meta-analysis comprehensively evaluated the diagnostic efficacy of various imaging modalities for prostate cancer across different stages. Our findings underscore the strengths and limitations of each imaging technique in detecting and staging prostate cancer.

The change of plasma lipid species has close contacts with gastric cancer (GC). However, the specific mechanism still needs to be explored further. We aim to utilize plasma proteins to decipher the association between lipid species and GC, and seek possible drug targets for GC. We performed a two-step Mendelian randomization (MR) analysis to investigate causal relationships among 179 lipid species, 4907 plasma proteins, and GC. Using summary-data-based MR and colocalization, we first examined protein–GC associations in discovery (N = 35,559) and validation (N = 54,219) cohorts. Subsequent MR analyses assessed lipid–GC and lipid–protein relationships, followed by mediation analysis using error propagation methods. Finally, macromolecular docking of prioritized proteins identified potential therapeutic ligands. Our MR analysis revealed causal relationships between 12 lipid species and GC, as well as 3 plasma proteins and GC. Importantly, mediation analysis demonstrated that CCDC80 protein mediates 2.90% (95% CI: 0.30–5.5%) of the protective effect of diacylglycerol (16:1_18:1) against GC. Based on these findings, we identified valproic acid as a promising therapeutic candidate targeting CCDC80 for GC treatment. Our study demonstrates that reduced CCDC80 expression mediates the tumor-promoting effects of diacylglycerol (16:1_18:1) in GC pathogenesis. Molecular docking confirms valproic acid binds stably to CCDC80, suggesting its therapeutic potential. These findings advance GC etiology understanding and provide a new drug development direction.

Introduction: The aim of the study was to explore potential factors affecting the emergence of sleep disorders in patients with renal failure.Material and methods: A cross-sectional study approach was employed in order to evaluate the relationship between renal failure and sleep disorders, and to validate the findings through Mendelian randomization (MR) analysis. Furthermore, we utilized a two-stage MR methodology to quantify the specific contribution of creatinine, mediated by sleep apnea syndrome, to the development of renal failure.Results: In the multivariate adjusted logistic regression analysis, compared to non-renal failure patients, time to fall asleep in minutes (OR = 0.01, 95% CI: 0.00–0.40, p = 0.022) was significantly reduced, while waking up during the night (OR = 0.73, 95% CI: 0.62–0.86, p = 0.003), feeling unrested during the day (OR = 0.65, 95% CI: 0.48–0.89, p = 0.015), and feeling overly sleepy during the day (OR = 0.67, 95% CI: 0.50–0.89, p = 0.014) were also decreased. In the study of sleep-related factors and renal failure, it was found that sleep apnea syndrome could serve as a mediating factor in mediating creatinine levels for the occurrence of chronic kidney failure (proportion mediated: 2.6%; 95% CI = 0.5–4.7%) and renal failure (proportion mediated: 4.3%; 95% CI = 0.2–8.3%).Conclusions: Compared to non-renal failure patients, patients with renal failure exhibit significantly reduced sleep onset time and sleep stability. Sleep apnea syndrome may act as a mediator, promoting creatinine-induced damage to the kidneys.
