Primary pulmonary colloid adenocarcinoma: A case report of a rare subtype.
Int J Surg Case Rep
October 2024
Article Synopsis
- Pulmonary colloid adenocarcinoma is a rare type of lung cancer, making its clinical features largely unknown; this report details a case of early-stage recurrence post-surgery.
- A 68-year-old man was found to have colloid adenocarcinoma after a shadow was detected on a chest X-ray, leading to surgery where the cancer was initially removed and staged as early as possible (IA2).
- Despite the belief that colloid adenocarcinoma has relatively slow progression, the case highlights that it can recur quickly, underscoring the need for following standard treatment guidelines for lung cancer.
Objectives: To determine cell-free mitochondrial DNA (mt-cfDNA) levels in tachycardia-induced cardiomyopathy (TIC) and non-TIC among atrial fibrillation (AF) cases.
Backgrounds: TIC is a reversible cardiomyopathy resulting from tachyarrhythmias, such as AF. The exact cause of TIC is not fully understood, but mitochondrial dysfunction has been reported in a variety of cardiomyopathies and may be involved in TIC as well.
Akkermansia muciniphila in the small intestine improves liver fibrosis in a murine liver cirrhosis model.
NPJ Biofilms Microbiomes

Article Synopsis
- * The antibiotic rifaximin (RFX) has been found to improve liver fibrosis and hyperammonemia in a murine model of LC, while also changing the composition of gut bacteria, particularly increasing levels of the beneficial genus Akkermansia.
- * The research presents the idea of a "small intestine-liver axis," proposing that administering the bacteria Akkermansia muciniphila could be a promising new treatment strategy for liver complications related to cirrhosis.
Background: TactiFlex is a next-generation catheter that is being used increasingly in ablation-treatment strategies. The purpose of this study was to investigate the differences in ablation lesions when the ablation power, time, and perfusion flow are varied with TactiFlex and TactiCath catheters.
Methods: The TactiFlex and TactiCath catheters were contacted perpendicularly/obliquely/parallel to the swine myocardium at varying powers (30, 40, and 50 W), time points (10, 15, 20, 25, 30, and 40 s), and forces (5, 10, 15, 20, and 30 g); the depth, width, and area of each lesion were measured, and the number of steam pops that occurred was counted.
