Stimulator of interferon genes (STING): Key therapeutic targets in ischemia/reperfusion injury
Biomed Pharmacother. 2023 Sep 10;167:115458. doi: 10.1016/j.biopha.2023.115458. Online ahead of print.ABSTRACTThe Stimulator of Interferon Genes (STING) is predominantly expressed in immune cells, including macrophages, natural killer cells, dendritic cells, and T cells, functioning as a pattern recognition receptor. STING activation upon detecting cytosolic DNA released from damaged cells initiates downstream pathways, leading to the production of inflammatory cytokines such as IFNs, IL-6, and TNF-α. Dysregulated STING activation has been implicated in inflammatory and metabolic diseases. Ischemia/reperfusion injury (I/R...

News at a glance: A win for obesity drugs, NIH unionization roadblocks, and Mexican fireflies under threat
CONSERVATION Researchers raise alarm over threat to Mexican fireflies Scientists from the International Union for Conservation of Nature (IUCN) last week delivered a letter to the Mexican government requesting it regulate tourism centered on the threatened firefly species Photinus palaciosi . Endemic to Mexico’s Tlaxcala forests, P. palaciosi is one of the few species that glow in synchrony, offering an annual spectacle that attracts thousands of visitors during summer mating season. The letter describes how littering, artificial light, and noise interfere with the insects’ courtship and eg...

Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers for adults with early (stage 1 to 3) non-diabetic chronic kidney disease
CONCLUSIONS: There is currently insufficient evidence to determine the effectiveness of ACEi or ARB in patients with stage 1 to 3 CKD who do not have DM. The available evidence is overall of very low certainty and high risk of bias. We have identified an area of large uncertainty for a group of patients who account for most of those diagnosed as having CKD.PMID:37466151 | DOI:10.1002/14651858.CD007751.pub3

Preoperative higher right ventricular stroke work index increases the risk of de novo aortic insufficiency after continuous-flow left ventricular assist device implantation
This study investigated the influence of preoperative hemodynamic parameters on de novo AI in CF-LVAD recipients. We reviewed 125 patients who underwent CF-LVAD implantation without concomitant AV surgery between 2005 and 2018. De novo AI was defined as moderate or severe AI in those with none or trivial preoperative AI. During mean 30  ± 16 months of CF-LVAD support, de novo AI-free rate was 86% and 67% at 1 and 2 years, respectively. Multivariable analysis showed that higher right ventricular stroke work index (RVSWI) (hazard ratio, 1.12 /g/m2/beat; 95% confidence interval, 1.00 –1.20;p = 0.047) and trivial ...

Outcomes of Combined Heart-Kidney Transplantation in Older Recipients
CONCLUSION: Combined HKT is increasing in older recipients, and advanced age ≥65 should not preclude HKT.PMID:37396466 | PMC:PMC10314816 | DOI:10.1155/2023/4528828
