Purpose: To determine the concentration of group IIA phospholipase A2 (GIIAPLA(2)) in tears of patients with keratoconjunctivitis sicca (KCS) and to compare it with the GIIAPLA(2) content of tears in age-matched healthy controls.

Methods: The GIIAPLA(2)content of tears was measured with time-resolved fluoroimmunoassay in 20 patients with KCS (mean age 70.7+/-8.7 years) and in 20 normal subjects (mean age 70.2+/-9.9 years).

Results: The GIIAPLA(2)content of tears in patients with KCS was 75.8+/-54.2 microg/ml and in normal subjects it was 34.2+/-21.4 microg/ml. The difference was statistically significant. In patients with KCS the GIIAPLA(2) concentration slightly increased with decreasing Schirmer test values (Spearman's correlation =-0.20)

Conclusion: The results of this study indicate that in patients with KCS the relative concentration of GIIAPLA(2) of tears was increased due to decreased aqueous production in the lacrimal glands and better preservation of the acinar cells in the central parts of the lobules of the lacrimal glands producing GIIAPLA(2).

Background & Aims: Metabolic dysfunction-associated steatotic liver (MASLD) progression is driven by chronic inflammation and fibrosis, largely influenced by Kupffer cell (KC) dynamics, particularly replenishment of pro-inflammatory monocyte-derived KCs (MoKCs) due to increased death of embryo-derived KCs. Adenosine A3 receptor (A3AR) plays a key role in regulating metabolism and immune responses, making it a promising therapeutic target. This study aimed to investigate the impact of selective A3AR antagonism for regulation of replenished MoKCs, thereby improving MASLD.

Liver transplantation is currently recognized as the most effective treatment for severe liver diseases. Although survival rates after liver transplantation have improved, rejection of the transplanted liver remains a significant cause of morbidity and transplant failure in patients. Our team previously discovered a close association between high GBP1 expression and acute rejection reactions following liver transplantation.

Cutting-edge research has expanded our understanding of the macrophage activation programs in liver diseases making this immune cell type a therapeutic target. Clinical data on macrophage infiltration and polarization states have been used to help predict mortality or poor prognosis in patients with liver cirrhosis and/or HCC. The latest single-cell and spatial transcriptomics studies have dissected unforeseen aspects depicting the immense heterogeneity of macrophages and their multifaceted role in both promoting and resolving hepatic inflammation, injury, and fibrosis.

Validation of administrative health data for the identification of endometriosis diagnosis.

Study Question: How do endometriosis diagnoses and subtypes reported in administrative health data compare with surgically confirmed disease?

Summary Answer: For endometriosis diagnosis, we observed substantial agreement and high sensitivity and specificity between administrative health data-International Classification of Diseases (ICD) 9 codes-and surgically confirmed diagnoses among participants who underwent gynecologic laparoscopy or laparotomy.

What Is Known Already: Several studies have assessed the validity of self-reported endometriosis in comparison to medical record reporting, finding strong confirmation. We previously reported high inter- and intra-surgeon agreement for endometriosis diagnosis in the Endometriosis, Natural History, Diagnosis, and Outcomes (ENDO) Study.

Rationale And Objectives: We aimed to compare the capabilities of two leading large language models (LLMs), GPT-4 and Gemini, in analyzing serial radiology reports, to highlight oncological issues that require further clinical attention.

Materials And Methods: This study included 205 patients, each with two consecutive radiological reports. We designed a prompt comprising a three-step task to analyze report findings using LLMs.
