Summary: Abdominal aortic aneurysm (AAA) is a common focal dilation of the aorta in the elderly population, which can lead to aneurysmal rupture with a mortality rate of around 80%. Despite increased screening efforts, there is currently no cure to halt the expansion of AAA, partly due to incomplete understanding of its pathogenesis. Animal models provide valuable insights into AAA pathophysiology, but no single experimental model fully captures the complexity of the disease.

Summary: This study found that the use of electronic cigarettes with nicotine can increase the development of abdominal aortic aneurysms and induce inflammation and the production of reactive oxygen species in the body. Furthermore, the study identified a key factor, CHI3L1/Chil1, in the development of e-cigarette-induced aneurysms.

Summary: In this study, the researchers investigated the effect of low-dose nicotine on the progression of elastase-induced abdominal aortic aneurysms (AAAs). They found that nicotine promotes AAA progression and reduces the activity of pro-matrix metalloproteinase 2 and MMP9 in aneurysmal tissue. However, nicotine has no effect on inflammatory response and oxidative stress. Therefore, these results do not support the use of low-dose nicotine for preventing AAA progression.

Summary: Research has shown that overexpression of FcγR has been detected in abdominal aortic aneurysm lesions, and inhibiting FcγR signaling molecules can reduce AAA development, restore inflammatory responses and vascular wall injury, potentially serving as therapeutic targets for AAA disease.

Summary: This study investigated the effect of sildenafil on experimental abdominal aortic aneurysm (AAA). The results showed that sildenafil application aggravated aortic wall dilation and elastin degradation, potentially worsening the progression of AAA. The study also found that sildenafil dysregulated cGMP and contractile signaling in smooth muscle cells (SMCs) in AAA.

Summary: A systematic review examined the correlation of abdominal aortic aneurysm expansion rates with serum circulating biomarkers, identifying specific biomarkers potentially useful for individualized surveillance of patients with increased AAA growth rates. Various biomarkers, including D-dimers, LDL-C, HDL-C, and genetic factors, were found to be significantly associated with AAA growth rates, suggesting a potential role for serum biomarkers in patient monitoring.

Summary: A novel AAA model combining porcine pancreatic elastase (PPE) and balloon dilation (BD) was constructed to mimic human AAA in terms of histomorphology, inflammatory cell infiltration, and vascular stromal destruction. The optimal BD time for rabbits was found to be 5 min, resulting in a 100% model formation rate. This model provides an ideal animal model for studying the pathogenesis of AAA.

Summary: Abdominal aortic aneurysms (AAA) are common in older adults and can lead to serious morbidity and mortality if not treated promptly. The causes include trauma, infection, and inflammatory disorders, with risk factors such as smoking, advanced age, dyslipidemia, hypertension, and coronary artery disease. The pathophysiology involves arterial insult leading to inflammation and weakening of the arterial wall, requiring monitoring of size and growth rate to prevent rupture. Management options include controlling risk factors, surgical intervention based on risk assessment, and post-operative monitoring for complications. Advancements in technology have improved the diagnosis and treatment of AAA in recent years.

Summary: The purinergic receptor P2X7 plays a crucial role in abdominal aortic aneurysm (AAA) development by modulating macrophage pyroptosis and inflammation. P2X7 is highly expressed in human AAA specimens and experimental murine AAA lesions. Inhibition or deficiency of P2X7 attenuates aneurysm formation in experimental murine models, while its activation promotes AAA development. Mechanistically, macrophage P2X7 activates the NLRP3 inflammasome and its downstream caspase-1 to initiate the pyroptosis pathway.

Summary: This overview examines the effectiveness, stakeholder perceptions, and cost-effectiveness of remotely delivered healthcare for diabetes-related foot disease (DFD). The study found that remotely delivered healthcare for DFD is well received by patients and clinicians, but its effectiveness remains unclear. More high-quality trials are needed to evaluate the risks and benefits of remotely delivered DFD management.

Summary: This study investigates the association between fasting triglycerides and cardiovascular disease mortality. The results show that higher triglyceride levels are associated with an increased risk of CVD mortality in patients with diabetes, but not in those without diabetes. This suggests that future treatments targeting triglyceride reduction should focus on patients with diabetes.

Summary: This study aimed to systematically review the incidence and risk factors for 30-day readmission to hospital following an index admission to treat diabetes-related foot disease (DFD). Meta-analysis found that approximately one-fifth of DFD patients were readmitted to hospital within 30 days, of which about half were to treat DFD. Risk factors for readmission included female gender, peripheral neuropathy, lack of private health insurance, and coronary artery disease.

Summary: This study aimed to identify the rates and predictive factors for hospital re-admission among patients with diabetes related foot disease (DFD). The results showed that over 50% of patients were re-admitted within one year, and patients with absent pedal pulses and loss of protective sensation (LOPS) were twice as likely to be re-admitted.

Summary: This study aimed to investigate the effect of the sympatholytic drug moxonidine on atherosclerosis. The results showed that moxonidine increased the uptake of oxidised LDL by vascular smooth muscle cells (VSMCs), as well as the expression of LDL receptors and the lipid efflux transporter ABCG1. Moxonidine also inhibited inflammatory gene expression and increased VSMC migration. In vivo experiments on ApoE(-/-) mice showed that moxonidine administration reduced atherosclerosis formation and increased plasma lipid hydroperoxide levels.

Summary: Peripheral artery disease (PAD) is a significant social and economic burden with gender disparities. Women may have equal or higher prevalence of PAD and experience worse clinical outcomes. The underlying reasons for these gender inequalities in PAD are unclear. A scoping review using the World Health Organization model was conducted to explore the complex factors contributing to gender-related inequities in the diagnosis, treatment, and management of PAD. Gaps in knowledge were identified, and recommendations for addressing these inequalities were discussed.

Summary: The purpose of this study was to understand patients' perspectives on the impact and prevention of diabetes-related foot disease (DFD). A survey was conducted among patients with a history of DFD, and the results showed that foot ulcers were the most common complication, with a significant number of patients having been admitted to the hospital or undergone amputation due to DFD. The study also revealed varying perceptions on the effect of DFD on health, the importance of offloading footwear for prevention, and mixed views on telehealth.

These methodologies have the potential to enhance diagnostic outcomes and reduce observer variability by extracting valuable information from large datasets beyond human perceptual capabilities. However, challenges such as limited sample sizes, diverse data sources, and the absence of standardized protocols hinder the widespread adoption of these techniques.
