Article Abstract

We investigated the relationship between the degree of alveolarization and ultrasound-assessed lung aeration in a validated preterm rabbit model of experimental bronchopulmonary dysplasia (BPD). Lung ultrasound findings were heterogeneously abnormal and consisted of zones with interstitial, interstitial-alveolar or consolidated patterns. The median radial alveolar count was 10.1 [8.4-11.5], 7.8 [6.1-9] and 7.3 [1.8-10.1] in rabbits with interstitial, interstitial-alveolar or consolidated ultrasound pattern, respectively (overall p = 0.036). Alveolar count and lung ultrasound score were significantly correlated (ρ = - 0.044 (95%CI: - 1; - 0.143), p = 0.009; τ = - 0.362 (95%CI: - 0.6; - 0.1), p = 0.017).

Purpose: Bronchiolar adenoma (BA) is a rare benign pulmonary neoplasm originating from the bronchial mucosal epithelium and mimics lung adenocarcinoma (LAC) both radiographically and microscopically. This study aimed to develop a nomogram for distinguishing BA from LAC by integrating clinical characteristics and artificial intelligence (AI)-derived histogram parameters across two medical centers.

Methods: This retrospective study included 215 patients with diagnoses confirmed by postoperative pathology from two medical centers.

Objectives: To evaluate the outcomes with lung changes of fetoscopic endoluminal tracheal occlusion (FETO) for congenital diaphragmatic hernia (CDH).

Methods: Between 2014 and 2023, we performed FETO for severe or moderate left-sided CDH with the Kitano Grade 3 stomach position. We analyzed the pre- and post-operative ultrasound findings, pregnancy outcomes, and survival rates at six months.

Background: Mucormycosis is a rare, rapidly progressive fungal infection with a high mortality rate. However, clinical data of mucormycosis patients, especially those related to adverse outcomes in China, remain limited.

Objective: To enhance understanding of the clinical characteristics of different infection site mucormycosis and identify the factors associated with adverse outcomes.

Baricitinib Combination Therapy Demonstrates Significant Improvement in Cardiac Conduction Defects in Rapidly Progressive Systemic Sclerosis: A Case Report.

Open Access Rheumatol

August 2025

Department of Rheumatology and Immunology, the First Affiliated Hospital, Jinan University, Guangzhou, 510632, People's Republic of China.

Objective: To evaluate the efficacy of baricitinib in combination therapy for managing refractory, rapidly progressive systemic sclerosis (SSc) with severe cardiac conduction defects and interstitial lung disease (ILD).

Methods: A 48-year-old male patient with SSc complicated by significant cardiac enlargement, third-degree atrioventricular block, heart failure, progressive ILD, and partial intestinal obstruction was included in the study. Prior treatments with mycophenolate mofetil (MMF), tacrolimus, and cyclophosphamide (CTX) had shown limited efficacy.
