I was sent the 2 ECGs shown in Figure-1 — which were recorded from an elderly man whose heart beat "has been irregular for years". No clear history for recent chest pain — but the patient "has not been well" for the previous week. Regarding the 2 ECGs in Figure-1 : ECG #1 is the initial tracing obtained at the scene by the EMS ( E mergency M edical S ystems ) team — in association with an alert but markedly hypotensive patient.

Long-term organ transplant survival remains suboptimal, and life-long immunosuppression predisposes transplant recipients to an increased risk of infection, malignancy, and kidney toxicity. Promoting the regulatory arm of the immune system by expanding Tregs may allow immunosuppression minimization and improve long-term graft outcomes. While low-dose IL-2 treatment can expand Tregs, it has a short half-life and off-target expansion of NK and effector T cells, limiting its clinical applicability.

Transcatheter aortic valve replacement (TAVR) is the standard treatment for severe aortic stenosis, but post-TAVR leaflet thrombus, identified by hypoattenuated leaflet thickening (HALT), poses potential risks like cerebral thromboembolic events. Perivalvular thrombus has also been reported. The ADAPT-TAVR study compared edoxaban with dual antiplatelet therapy (DAPT) to prevent leaflet thrombus and associated risks post-TAVR.

Patients with chronic inflammatory disorders such as psoriasis have an increased risk of cardiovascular disease and elevated levels of LL37, a cathelicidin host defense peptide that has both antimicrobial and proinflammatory properties. To explore whether LL37 could contribute to the risk of heart disease, we examined its effects on lipoprotein metabolism and show that LL37 enhanced LDL uptake in macrophages through the LDL receptor (LDLR), scavenger receptor class B member 1 (SR-B1), and CD36.

Nuclear factor of activated T-cells 5 (NFAT5), an osmo-sensitive transcription factor, can be activated by isotonic stimuli, such as infection. It remains unclear, however, whether NFAT5 is required for damage-associated molecular pattern–triggered (DAMP-triggered) inflammation and immunity. Here, we found that several DAMPs increased NFAT5 expression in macrophages.

Most people only start to worry about cardiovascular risk later in life. This is a bad idea. Here’s why. When you look at the risk of having a heart attack, it is true that the older you are, the greater the odds of having a heart attack 1. So far, so good. But this graph is very misleading. While only 1-2% of those having a heart attack are less than 65 years of age, 1-2% of this very large number means a LOT of heart attacks.

However, the therapeutic strategies targeting opioid-responsive dopaminergic ensembles that contribute to the development of opioid withdrawal remain to be elucidated. Here, we used the neuronal activity-dependent Tet-Off system to label dopaminergic ensembles in response to initial morphine exposure (Mor-Ens) in the ventral tegmental area (VTA).

Two coding variants of apolipoprotein L1 (APOL1), called G1 and G2, explain much of the excess risk of kidney disease in African Americans. While various cytotoxic phenotypes have been reported in experimental models, the proximal mechanism by which G1 and G2 cause kidney disease is poorly understood. Here, we leveraged 3 experimental models and a recently reported small molecule blocker of APOL1 protein, VX-147, to identify the upstream mechanism of G1-induced cytotoxicity.

Pulmonary surfactant is a lipoprotein complex lining the alveolar surface to decrease the surface tension and facilitate inspiration. Surfactant deficiency is often seen in premature infants and in children and adults with respiratory distress syndrome. Mechanical stretch of alveolar type 2 epithelial (AT2) cells during lung expansion is the primary physiological factor that stimulates surfactant secretion; however, it is unclear whether there is a mechanosensor dedicated to this process.
