AI Article Synopsis

  • There is a growing interest in non-invasive methods to detect subclinical atherosclerosis in order to identify patients at high risk for cardiovascular events, particularly in those with diabetes mellitus (DM) and peripheral arterial disease (PAD) during acute coronary syndrome (ACS).
  • A study involving 1,410 ACS patients found that the prevalence of PAD was significantly higher in those with DM (41.5%) compared to those without (30.6%), and patients with both conditions faced more in-hospital cardiac complications and a potential increase in mortality.
  • The combination of DM and PAD serves as a marker for identifying patients at greater risk, while in patients without PAD, DM was linked to three-vessel coronary disease, but this association did not hold in patients

Article Abstract

Background: There is an increasing interest in the use of non-invasive methods for the detection of subclinical atherosclerosis to better identify patients with high risk of cardiovascular events The presence of diabetes mellitus (DM) and peripheral arterial disease (PAD) is associated with increased risk of events but their value in the acute coronary syndrome (ACS) patient has not been ascertained.

Methods: We performed a subanalysis of the PAMISCA study, designed to investigate the prevalence of PAD in patients admitted to Spanish hospitals with a diagnosis of an ACS.

Results: A total of 1410 patients were analysed (71.4% men, age 66 +/- 11.9 years, 35% DM). The prevalence of PAD was higher in DM vs. no-DM (41.5% vs. 30.6% respectively, p < 0.001). Patients with PAD and DM had more in-hospital cardiac complications such as atrial fibrillation/flutter, recurrent myocardial ischaemia and heart failure and a trend towards higher in-hospital mortality (p = 0.08). Non-DM patients with PAD and DM without PAD shared similar cardiac complications and the group without neither PAD nor DM had the best prognosis. In patients without PAD, DM was an independent predictor of three-vessel coronary disease (OR 1.6; 95% CI: 1.1-2.5, p < 0.05) after adjustment by age, sex, low density lipoproteins (LDL), smoking and the previous myocardial infarction. However, in PAD patients, DM failed to be an independent risk factor in the multivariate analysis (OR 1.0; 95% CI 0.6-1.6, p < 0.05).

Conclusions: The concurrence of DM and PAD helps identify patients with an adverse risk profile.

Background: Despite constant improvements, incontinence is one of the most relevant and quality-of-life-reducing side effects of radical prostatectomy (RP) and, in addition to patient-specific factors such as age, the experience of the surgeon/center and the surgical technique used play an important role.

Aims: To present current real-world data on short-term incontinence after RP from one of the largest German rehabilitation centers in 2022 and to compare it to the results from the same institution in 2016.

Methods And Results: Retrospective, unicentric, univariate analysis of data from 1394 men after RP in 2022 on admission and discharge from the rehabilitation clinic.

Intravascular ultrasound (IVUS) has become a standard procedure for performing coronary intervention, but its impact on peripheral endovascular therapy (EVT) remains unclear. To assess the usefulness of IVUS during EVT, this study analyzed over 2000 consecutive patients from the TOkyo-taMA peripheral vascular intervention research COmraDE (TOMA-CODE) registry with peripheral arterial disease (PAD) in Japan. The primary outcome was chronic limb events (a composite of clinically driven target lesion revascularization (cTLR) and major amputation) during a two-year follow-up period.

Background: The most common cause of death in patients with peripheral artery disease (PAD) are major adverse cardiovascular events (MACEs), including myocardial infarction (MI) and stroke. However, data on biomarkers that could be used to help predict MACEs in patients with PAD to guide clinical decision making is limited. Angiogenesis-related proteins have been demonstrated to play an important role in systemic atherosclerosis and may act as prognostic biomarkers for MACEs in patients with PAD.

Detecting and tracking the preclinical stages of Alzheimer's disease (AD) is now of particular interest due to the aging of the world's population. AD is the most common cause of dementia, affecting the daily lives of those afflicted. Approaches in development can accelerate the evaluation of the preclinical stages of AD and facilitate early treatment and the prevention of symptom progression.

Background: Loss or displacement of a fat pad on the foot increases plantar pressure, leading to pain and plantar ulcers. These ulcers, especially in patients with diabetic neuropathy, have high recurrence rates, often resulting in amputations. Standard of care focuses on reducing plantar pressure with shoe padding or orthotic devices, leaving the restoration of the fat pad as an unmet medical need.
