Key Anesthesiology Insights:
- Preoperative albumin levels and length of hospital stay in non-cardiac surgery patients with pulmonary hypertension: A secondary retrospective analysis of 195 patients with pulmonary hypertension (PHTN) undergoing non-cardiac, non-obstetric surgery found that low levels of preoperative albumin were associated with an increased risk of prolonged hospital stay. This suggests that optimizing preoperative nutrition could potentially reduce the length of hospital stay in these patients. PMID: 38847677
- Resistin as a biomarker for disease severity and survival in patients with pulmonary arterial hypertension: A study involving 1121 adults with pulmonary arterial hypertension (PAH) found that high resistin levels were associated with older age, shorter 6-min walk distance, reduced cardiac performance, and an increased risk of death. The study suggests that resistin plays an important role in the pathobiology of human PAH and represents a novel biomarker for prognostication. PMID: 38844967
- Post-cardiac surgery transcriptomes of monocytes differ even at three months compared to baselines: A study of 13 patients admitted for elective cardiac surgery found that monocytes and T cells had distinct transcriptomes, with statistically significant differential expression of 558 T cell related genes. The authors concluded that the post-cardiac surgery transcriptomes of monocytes differ even at three months compared to baselines, which may reflect latent inflammation and persistent progression of tissue degenerative processes. PMID: 38851465
In-Depth Analysis:
In a study investigating the use of a novel non-invasive echocardiographic parameter, Pressure-Strain Product (PSP), as a potential surrogate for catheter-based left ventricular stroke work index (LVSWI) in an ovine model of brain stem death (BSD) donors, researchers found that PSP(circ) had the best correlation with LVSWI among other echocardiographic parameters. The study suggests that PSP(circ) could be used as a surrogate for catheter-based LVSWI, reflecting mitochondrial function. This finding could have significant implications for the assessment of cardiac function in BSD donors. PMID: 38845111
Another study aimed to assess whether the choice of anesthesia (locoregional anesthesia or general anesthesia) influences the rates of perioperative complications in patients with congestive heart failure (CHF) undergoing carotid endarterectomy (CEA). The study found that locoregional anesthesia was independently associated with lower rates of MI, acute HF, major cardiac complications, hemodynamic instability, cranial nerve injury, shunt use, and neuromonitoring device use compared to general anesthesia in symptomatic CHF patients. This suggests that CEA can be safely performed in patients with CHF, and utilizing locoregional anesthesia is associated with a decreased incidence of perioperative cardiac complications in patients with symptomatic heart failure undergoing CEA. PMID: 38851468
In a study investigating the pathological mechanisms of depression, researchers induced depression-like behavior in a rat model and conducted various behavioral tests to assess depressive-like behavior. The study identified five differentially expressed phosphorylated proteins (DEPPs) – Gys1, Nmt2, Lrp1, Bin1, and Atp1a1. These proteins were found to activate the synaptogenesis signaling pathway, induce mitochondrial dysfunction, and activate the phosphoinositide biosynthesis and degradation pathways. The study also confirmed the proteomic findings for Gys1, Nmt2, Lrp1, and Atp1a1 using qRT-PCR. Notably, inhibiting Nmt2 was found to alleviate depression-like behavior and neuronal apoptosis in the hippocampus of rats with chronic unpredictable mild stress (CUMS). The article concludes that these findings provide new insights into the molecular mechanisms of depression and suggest NMT2 as a potential target for depression treatment or diagnosis. PMID: 38852542
