AI Article Synopsis
- - The study analyzed risk factors for abdominal aortic aneurysm (AAA) development in adults over 50 with diabetes, highlighting that despite diabetes being linked to a lower AAA risk, some patients still develop it.
- - It followed over 1.9 million participants from 2009 to 2019 and found factors like age, male gender, smoking, and certain health issues (e.g., hypertension) increased AAA risk, while longer diabetes duration and specific oral medications decreased risk.
- - Notably, the research indicated that heavy alcohol consumption and obesity were linked to lower AAA risk, whereas insulin use marginally increased risk, showcasing a complex relationship between diabetes management and AAA development.
Article Abstract
Objective: Although diabetes has been shown to be negatively associated with development of abdominal aortic aneurysm (AAA), patients with diabetes may still develop aneurysms. In this study, we examined risk factors for the development of AAA in patients with diabetes.
Methods: Adults >50 years of age with diabetes who underwent health screening between 2009 and 2012 were followed for incident AAA until December 31, 2019. Cox proportional hazard regression models were used to calculate multivariate hazard ratios (HRs) and 95% confidence intervals (CIs) for risk factors associated with AAA.
Results: Among 1,913,066 participants (55.3% men), 6996 AAA cases were identified during a mean follow-up of 7.7 years. Increased AAA risk was observed for age ≥65 years (HR, 2.69; 95% CI, 2.55-2.83), men (HR, 1.81; 95% CI, 1.69-1.94), smoking (former smoker ≥20 pack-years [PY]; HR, 1.75; 95% CI, 1.61-1.89; current smoker <20 PY; HR, 1.76; 95% CI, 1.59-1.94; current smoker ≥20 PY; HR, 2.40; 95% CI, 2.23-2.59), abdominal obesity (HR, 1.30; 95% CI, 1.23-1.38), and comorbidities, including hypertension (HR, 1.63; 95% CI, 1.53-1.73), dyslipidemia (HR, 1.35; 95% CI, 1.29-1.42), chronic kidney disease (HR, 1.52; 95% CI, 1.44-1.61), and cardiovascular disease (HR, 1.71; 95% CI, 1.58-1.86). Heavy (HR, 0.67; 95% CI, 0.61-0.74) and mild alcohol consumption (HR, 0.78; 95% CI, 0.74-0.83), overweight (HR, 0.87; 95% CI, 0.81-0.93) and obesity (HR, 0.81; 95% CI, 0.75-0.87), longer diabetes duration (≥5 years: HR, 0.74; 95% CI, 0.70-0.78), and using three or more oral hypoglycemic agents (OHA) (HR, 0.84; 95% CI, 0.79-0.90) were associated with decreased AAA risk, whereas insulin use was associated with a marginally increased risk (HR, 1.09; 95% CI, 1.00-1.18). Among the OHAs, metformin (HR, 0.95; 95% CI, 0.90-1.00), thiazolidinediones (HR, 0.87; 95% CI, 0.79-0.97), and sulfonylureas (HR, 0.88; 95% CI, 0.83-0.93) were associated with a decreased risk of AAA.
Conclusions: Although diabetes is associated with decreased AAA risk, those with comorbid cardiometabolic diseases, abdominal obesity, and a smoking history should be aware of an increased AAA risk. Further studies are warranted to verify the potential use of OHAs for decreasing AAA risk.

Association of trimethylamine N-oxide and metabolites with kidney function decline in patients with chronic kidney disease.

Background: Trimethylamine N-oxide (TMAO) is a gut microbial metabolite derived from dietary l-carnitine and choline. High plasma TMAO levels are associated with cardiovascular disease and overall mortality, but little is known about the associations of TMAO and related metabolites with the risk of kidney function decline among patients with chronic kidney disease (CKD).
Methods: We prospectively followed 152 nondialysis patients with CKD stages 3-5 and measured plasma TMAO and related metabolites (trimethylamine [TMA], choline, carnitine, and γ-butyrobetaine) via liquid chromatography‒mass spectrometry.

Introduction: Alpha-1 adrenergic receptor antagonist (α1-ARA) are well established treatment for benign prostatic hyperplasia (BPH)-associated lower urinary tract symptoms (LUTS). Since BPH and erectile dysfunction (ED) are commonly concomitant conditions, the importance of addressing the potential role of α1-ARA in patients with ED is rising.
Methods: We systemically reviewed literature for studies that assessed erectile function (EF) indices in relation to α1-ARA use.

Introduction: Acute myocardial infarction (AMI) poses a significant global health burden, warranting meticulous management strategies, particularly in patients with concurrent anemia. Blood transfusion strategies play a pivotal role in optimizing oxygen delivery while minimizing transfusion-related risks. Two contrasting approaches, liberal and restrictive transfusion strategies, have emerged, yet their comparative effectiveness remains uncertain due to conflicting evidence.

The E6 and E7 proteins of the high risk human papillomaviruses (HR HPVs) play a key role in the oncogenesis associated with papillomavirus infection. Data on the variability of these proteins are limited, and the factors affecting their variability are still poorly understood. We analyzed the variability of the currently known sequences of the HPV type 16 (HPV16) E6 and E7 proteins, taking into account their geographic origin and year of sample collection, as well as the direction of their evolution in the major geographic regions of the world.

The gut microbiota is a crucial link between diet and cardiovascular disease (CVD). Using fecal metaproteomics, a method that concurrently captures human gut and microbiome proteins, we determined the crosstalk between gut microbiome, diet, gut health, and CVD. Traditional CVD risk factors (age, BMI, sex, blood pressure) explained < 10% of the proteome variance.
