Peripheral arterial disease (PAD) is one clinical manifestation of systemic atherosclerosis and is very common. Despite its prevalence, PAD remains underdiagnosed, undertreated, and understudied. The most common symptom in patients with PAD is intermittent claudication (IC), or pain in the lower extremities with walking or exertion, which is relieved after a short period of rest.

Pregnancy-associated breast cancer is challenging to treat. Treatment with chemotherapeutic agents such as anthracyclines poses a risk of cardiotoxicity, despite being considered safe after the second trimester of pregnancy. Management requires multidisciplinary comanagement with cardio-obstetrics, cardiology-oncology, maternal-fetal medicine, and oncology.

Article Synopsis
  • Researchers analyzed cardiovascular event patterns in patients with type 2 diabetes using data from the TECOS trial, focusing on a composite of major adverse cardiovascular events (MACE-4).
  • They found that event rates for both fatal and nonfatal outcomes remained relatively constant over the trial period, suggesting traditional prediction models can be reliably used for estimating event accrual.
  • The study highlighted the importance of monitoring the adjudication gap, which is the time between when events occur and when they are officially recognized, as it improves over the course of the trial.

Article Synopsis
  • - The study examined the link between low cognitive scores, measured by the MoCA and DSST, and the risk of cardiovascular events among participants in the REWIND trial, focusing on those with significant cognitive impairment (SCI).
  • - Out of 8,772 participants, 905 (10.3%) with SCI experienced a higher incidence of major adverse cardiovascular events (MACE) and a greater risk of stroke or death compared to those without (89.7%).
  • - Stronger associations were observed for a composite measure (SCI-GM), which remained significant even after adjusting for various risk factors, indicating that standardized cognitive impairment is a strong predictor of cardiovascular risks in individuals with type 2 diabetes.

Indigenous communities are often on the front-lines of climate change, and for tribes such as the Pointe-au-Chien Indian Tribe (PACIT) that make their homes and livelihoods in the dynamic landscapes of Coastal Louisiana (USA), sea-level rise, subsidence, and land loss are very real reminders of why they must continue to hone their adaptive capacity that has evolved over many generations and continues to evolve as the pace of change quickens. PACIT members have an inherited wisdom about their surrounding environment and continue to build on that body of observational knowledge that is passed from generation to generation to sustain themselves in this dynamic landscape. This knowledge is woven through their culture and is sometimes referred to as traditional ecological knowledge (TEK).

Article Synopsis
  • The study aimed to assess the effectiveness and safety of higher doses of dulaglutide (3.0 and 4.5 mg) compared to the standard dose (1.5 mg) in patients with diabetes who are also taking metformin, specifically examining groups based on age (under 65 and 65 or older).
  • A total of 1,842 patients were analyzed, revealing that both age groups experienced greater reductions in blood sugar levels (HbA1c) and body weight with the higher doses of dulaglutide, with no significant differences based on age.
  • The research found that the higher doses resulted in meaningful improvement in diabetes management without increased safety risks, as the safety profiles were comparable across all age

Article Synopsis
  • Long-term glucose control can lower retinopathy risk, but treatment intensification sometimes worsens it; GLP-1RA's long-term effects on retinopathy need more assessment despite cardiovascular trials providing valuable data.
  • Six placebo-controlled GLP-1RA cardiovascular trials were reviewed for retinopathy outcomes, revealing no direct link between GLP-1RA treatment and retinopathy, but an association with HbA reductions was found.
  • Findings indicate that while reductions in HbA are linked to a higher risk of retinopathy, the studies lacked robust power and had varying methods, limiting clear conclusions on GLP-1RA's impact over longer periods.

Background: EXSCEL (Exenatide Study of Cardiovascular Event Lowering) assessed the impact of once-weekly exenatide 2 mg versus placebo in patients with type 2 diabetes mellitus, while aiming for glycemic equipoise. Consequently, greater drop-in of open-label glucose-lowering medications occurred in the placebo group. Accordingly, we explored the potential effects of their unbalanced use on major adverse cardiovascular events (MACE), defined as cardiovascular death, nonfatal myocardial infarction or nonfatal stroke, and all-cause mortality (ACM), given that some of these agents are cardioprotective.

Aim: To assess whether the previously developed multivariable risk prediction framework (PRE score) could predict the renal effects observed in the EXSCEL cardiovascular outcomes trial using short-term changes in cardio-renal risk markers.

Materials And Methods: Changes from baseline to 6 months in HbA1c, systolic blood pressure (SBP), body mass index (BMI), haemoglobin, total cholesterol, and new micro- or macroalbuminuria were evaluated. The renal outcomes were defined as a composite of a sustained 30% or 40% decline in estimated glomerular filtration rate (eGFR) or end-stage renal disease (ESRD).

Background: Alpha-glucosidase inhibitors (AGIs) have been shown to reduce incident type 2 diabetes but their impact on cardiovascular (CV) disease remains controversial. We sought to identify the overall impact of AGIs with respect to incident type 2 diabetes in individuals with impaired glucose tolerance (IGT), and CV outcomes in those with IGT or type 2 diabetes.

Methods: We used PubMed and SCOPUS to identify randomized controlled trials reporting the incidence of type 2 diabetes and/or CV outcomes that had compared AGIs with placebo in populations with IGT or type 2 diabetes, with or without established CV disease.
