Objective: To investigate the optic disc changes (ODC) in Chinese patients with -associated autoinflammatory disease (-AID).

Methods: Patients who were diagnosed with -AID at the Department of Rheumatology, Peking Union Medical College Hospital between April 2015 and December 2022 were retrospectively reviewed and analyzed.

Results: A total of 20 patients were enrolled in this retrospective study. All 20 patients had a moderate MWS -AID phenotype. Thirteen patients (65%) had ocular involvements. The interval between symptoms onset and diagnosis was significantly longer in patients with ocular involvement than in patients without ( = 0.044). The incidence of hearing loss was significantly higher in patients with ocular involvement ( = 0.017), while the incidence of abdominal pain was significantly lower when compared to patients without ocular involvement ( = 0.007). Optic disc swelling (ODS) (50%) was the most common ODC. All of the four T348M mutation carriers within our cohort exhibited ODS with visual-field defects. There was a significant difference between patients with/without ODS regarding the number of patients carrying T348M mutation ( = 0.014). The occurrence of hearing loss and CNS involvement was significantly higher in the group with ODS compared to the group without ( = 0.0014,  = 0.0198). Of the eight patients who underwent lumbar puncture, five presented with intracranial hypertension (IH). ODS was observed in all patients with IH. The serum inflammatory markers were significantly higher in patients with ODS than in those without. Two patients receiving regular subcutaneous IL-1 inhibitor treatment showed improvements in ODC.

Conclusions: ODC is common among Chinese patients with NLRP3-AID, with ODS being the most common manifestation. Hearing loss and CNS involvement often accompany the occurrence of ODS. The serum inflammatory markers are associated with ODS. The T348M mutation is more likely to lead to ODC with visual-field defects.

Introduction: Antibody-drug conjugates (ADCs) trastuzumab-deruxtecan (T-DXd) and sacituzumab-govitecan (SG) provided significant progression-free survival (PFS) and overall survival (OS) improvements over chemotherapy (CT) in pretreated hormone receptor-positive (HR+) and triple-negative (TN)/HER2-low metastatic breast cancer (MBC). However, no direct comparison between the two exists, nor with the more recent datopotamab-deruxtecan (Dato-DXd).

Methods: We conducted a network meta-analysis (NMA) to compare efficacy and safety of T-DXd and SG in CT-pretreated HR+ and TN/HER2-low MBC and assess their benefit over standard CT, exploring also a comparison with Dato-DXd.

Background: Primary pulmonary lymphoepithelioma-like carcinoma (PLELC) is a rare subtype of non-small-cell lung cancer. This study aims to compare the efficacy and safety of perioperative PD-1/PD-L1 inhibitor plus chemotherapy versus chemotherapy alone in stage II-IIIB PLELC patients.

Patients And Methods: This retrospective study included stage II-IIIB PLELC patients.

Background: The upfront treatment of non-oncogene-addicted NSCLC relies on immunotherapy alone (ICI) or in combination with chemotherapy (CT-ICI). Genomic aberrations such as KRAS, TP53, KEAP1, SMARCA4, or STK11 may impact survival outcomes.

Methods: We performed an observational study of 145 patients treated with first-line IO or CT-ICI for advanced non-squamous (nsq) NSCLC at our institution tested with an extensive lab-developed NGS panel.

Association of trimethylamine N-oxide and metabolites with kidney function decline in patients with chronic kidney disease.

Clin Nutr

Background: Trimethylamine N-oxide (TMAO) is a gut microbial metabolite derived from dietary l-carnitine and choline. High plasma TMAO levels are associated with cardiovascular disease and overall mortality, but little is known about the associations of TMAO and related metabolites with the risk of kidney function decline among patients with chronic kidney disease (CKD).

Methods: We prospectively followed 152 nondialysis patients with CKD stages 3-5 and measured plasma TMAO and related metabolites (trimethylamine [TMA], choline, carnitine, and γ-butyrobetaine) via liquid chromatography‒mass spectrometry.
