Background: Cholecystectomy (CCE) can affect the enterohepatic circulation of bile acids and result in gut microbiome changes. This systematic review aimed to clarify the effect of CCE on gut microbiome composition and its clinical impact.
Method: A systematic search was conducted in PubMed, Web of Science, and Scopus, combining keywords such as "cholecystectomy" or "post-cholecystectomy" with "gut microbiome," "stool microbiome," or "gut dysbiosis.
Vascular fibrosis and extracellular matrix remodelling in post-COVID 19 conditions.
Infect Med (Beijing)
December 2024
Causal associations between viral infections and acute myocardial injury are not fully understood, with mechanisms potentially involving direct cardiovascular involvement or systemic inflammation. This review explores plausible mechanisms of vascular fibrosis in patients with post-COVID-19 syndrome, focusing on extracellular matrix remodelling. Despite global attention, significant mechanistic or translational breakthroughs in the management of post-viral syndromes remain limited.

- The study investigates the link between atherosclerosis (plaque buildup in arteries) and types of myocardial ischemia (insufficient blood flow to the heart) in patients without significant coronary artery blockage (INOCA).
- It employs advanced invasive tests to assess coronary microvascular function and quantifies plaque burden using the Gensini score, which takes into account the severity of artery blockage.
- Findings reveal that higher Gensini scores correlate with poorer microvascular function, and different INOCA endotypes (like microvascular angina and vasospastic angina) show variations in plaque scores, indicating the complexity of heart conditions in patients without obvious artery blockage.
Background: Superior Mesenteric Artery Syndrome (SMAS) is a very rare disease that causes starvation and malnutrition secondary to a mechanical obstruction of the 3 portion of the duodenum between the superior mesenteric artery and aorta. Long-term outcomes following surgery for SMAS by current methods have a high failure rate of 21%-67%. We report the 3-year outcomes of a novel operation for SMAS described as the duodenoduodenostomy (DD).
