Aortic aneurysms represent a very common pathology that can affect any segment of the aorta. These types of aneurysms can be localized on the thoracic segment or on the abdominal portion, with the latter being more frequent. Though there are similarities between thoracic and abdominal aortic aneurysms, these pathologies are distinct entities. In this article, we undertook a review regarding the different mechanisms that can lead to the development of aortic aneurysm, and we tried to identify the different manners of treatment. For a long time, aortic wall aneurysms may evolve in an asymptomatic manner, but this progressive dilatation of the aneurysm can lead to a potentially fatal complication consisting in aortic rupture. Because there are limited therapies that may delay or prevent the development of acute aortic syndromes, surgical management remains the most common manner of treatment. Even though, surgical management has improved much in the last years, thus becoming less invasive and sophisticated, the morbi-mortality linked to these therapies remains increased. The identification of the cellular and molecular networks triggering the formation of aneurysm would permit the discovery of modern therapeutic targets. Molecular and cellular mechanisms are gaining a bigger importance in the complex pathogenesis of aortic aneurysms. Future studies must be developed to compare the findings seen in human tissue and animal models of aortic aneurysm, so that clinically relevant conclusions about the aortic aneurysm formation and the pharmacological possibility of pathogenic pathways blockage can be drawn.

Aging hemophiliacs face cardiovascular disease. Lots of evidence has been gathered that hemophiliacs have a more unfavorable cardiovascular profile than the general population does, especially due to the increased prevalence of hypertension (HTN). Among the existing scattered evidence, our study provides the most comprehensive and systematized analysis of the determinants of HTN in hemophiliacs. We discussed the contribution to the HTN substrate of hemophilia-specific factors, such as type, severity and the presence of inhibitors. The complex mechanism of kidney dysfunction in relation to hematuria and viral infections was meticulously addressed. Furthermore, we highlighted the new pathogenic concepts of endothelial dysfunction and the association between HTN and hemophilic arthropathy. The clustering of cardiovascular risk factors is common in hemophiliacs, and it enhances the negative vascular effect of HTN and aggravates HTN. It usually leads to an increased risk for coronary and cerebrovascular events. Our work provides reliable evidence to guide and improve the management of HTN in hemophiliacs.

Gallbladder carcinoma (GBC) is one of the most aggressive malignancies of the biliary tract, often originating from chronic inflammation associated with gallstones and cholecystitis. Persistent inflammation plays a pivotal role in the development of preneoplastic changes, such as metaplasia, which may progress to malignancy. Despite its relatively low incidence, GBC is characterized by a poor prognosis due to late-stage diagnosis, highlighting the urgent need for improved early detection strategies. This study aimed to assess the diagnostic and prognostic significance of CA 19-9 and CEA levels in patients with gallbladder lesions, while also evaluating systemic inflammation and hemostatic dysregulation. A retrospective analysis was conducted on patients diagnosed with gallbladder lesions, with histopathological confirmation of adenocarcinoma and metaplasia. Laboratory assessments included serum levels of tumour markers, inflammatory markers such as CRP, and key hemostatic parameters, including thrombocyte count, prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen levels. A predictive scoring model was developed using the cutoff values of CA 19-9 and CEA to assess their combined diagnostic potential. Among the patients studied, 48.9% had an initial diagnosis of chronic cholecystitis, while 32.2% presented with acute cholecystitis. Adenocarcinoma was identified in 6.7% of cases after histopathological examination, predominantly in females over 65 years old with acute cholecystitis. Metaplasia was detected in 7.8% of cases, primarily in elderly females with chronic cholecystitis. Laboratory findings revealed significantly elevated levels of CA 19-9, CEA, AFP, and CA-125 in patients with adenocarcinoma. Additionally, abnormalities in hemostatic parameters, including increased fibrinogen levels and alterations in thrombocyte count, were observed in patients with malignancy. A combined predictive score using CA 19-9 and CEA demonstrated strong potential for detecting adenocarcinoma and metaplasia, improving diagnostic accuracy. Our findings emphasize the clinical importance of integrating tumour markers, inflammatory biomarkers, and hemostatic parameters in the evaluation of gallbladder lesions associated with chronic inflammation. The combined assessment of these factors enhances early detection, facilitates malignancy risk stratification, and improves prognostic evaluation, particularly in patients with metabolic and cardiovascular comorbidities.

Since its discovery in 1898, the renin-angiotensin-aldosterone system (RAAS) has been intensely studied in the medical community, which led to important breakthroughs concerning the treatment of heart diseases. The main role of RAAS is to maintain the circulatory homeostasis, by maintaining the fluid volume. Angiotensin II (ANG II) can act on two receptors: angiotensin type 1 and angiotensin type 2 (AT1R and AT2R). The effect of AT1R consists in increased sodium retention, promotes vasoconstriction (mostly on the efferent arteriole), induces sympathetic nervous system activity, determines thirst and promotes the release of aldosterone. Abnormal activation of RAAS will determine hypertension and cardiac hypertrophy that may lead to heart failure. This is the reason why the pharmacological inhibition of this system has proven to induce such a beneficial effect in cardiovascular diseases such as hypertension and congestive heart failure. Later studies of patients with coronary artery disease revealed that angiotensin-converting enzyme (ACE) gene is also involved in the process of atherosclerosis and those mutations in its gene account for an increased susceptibility to severe acute coronary events. The most common ACE gene mutation is represented by deletions and insertions in the 16th intron (presence or absence of the 287-bp Alu repeat sequence), resulting in three possible genotypes, identified by the length of the fragments: II (490 bp), ID (490, 190 bp) and DD (190 bp). Scientific evidence suggests that the D allele plays a major role in the determination of coronary artery disease. The next step would be to develop new treatment strategies according to the genetic background of each patient.

Atherosclerosis is the main cause of myocardial infarction. This process involves a complex interplay between metabolic pathways governing lipid deposition, inflammatory and immune responses to oxidized lipids, and endothelial dysfunction. Myocardial infarction appears when these processes culminate with a thrombotic event. Markers of inflammation, such as C-reactive protein (CRP), myeloperoxidase (MPO) and leukocyte levels are strong predictors of cardiovascular death, myocardial infarction, and stroke. This process involves a complex interplay between metabolic pathways governing lipid deposition, inflammatory and immune responses to oxidized lipids, and endothelial dysfunction. Myocardial infarction appears when these processes culminate with a thrombotic event. Markers of inflammation, such as C-reactive protein (CRP), myeloperoxidase (MPO) and leukocyte levels are strong predictors of cardiovascular death, myocardial infarction, and stroke. This review will summarize the molecular and cellular links between inflammation and thrombosis in the context of myocardial infarction, which support the concept of a thrombo inflammatory state leading to the vessel obstruction and to the subsequent myocardial necrosis.
