The underlying mechanism of postoperative delirium (POD) in elderly people remains unclear. Perioperative hyperglycemia (POHG) is an independent risk indicator for POD, particularly in the elderly. Under cerebral desaturation (hypoxia) during general anesthesia, hypoxia-inducible factor (HIF) is neuroprotective during cerebral hypoxia via diverse pathways, like glucose metabolism and angiogenesis. ⋯ For surgical stress, hypothalamic-pituitary-adrenal activation and sympathoadrenal activation may increase endogenous glucose production via gluconeogenesis and glycogenolysis. Thus, under the setting of cerebral hypoxia during general anesthesia, we speculate that POHG prevents HIF-1α levels and function in the brain of aged patients, thus exacerbating the hypoxic response of HIF-1 and potentially contributing to POD. This paper sketches the underlying mechanisms of HIF in POD in elderly patients and offers novel insights into targets for preventing or treating POD in the same way as POHG.

Case Reports
Snare device retrieval of occluder embolized in patent foramen ovale closure: A case report.
Transcatheter interventional closure therapy is the main treatment method for patent foramen ovale (PFO). However, occluder abscission is a serious complication in PFO interventional therapy. Thus, timely and effective management of the occluder detachment is crucial for improving patient prognosis. ⋯ When the PFO occlusion device is detached, interventional treatment would lead to minimal trauma, fast postoperative recovery, and a definite therapeutic effect. Based on mastering the indications and standardizing the operational process, this is a safe and effective minimally invasive treatment method.

The effect of proprotein convertase subtilisin kexin type (PCSK9) inhibitors on blood lipids and major adverse cardiovascular events (MACEs) is still controversial for acute coronary syndrome (ACS) patients. This study aimed to evaluate the efficacy and safety of PCSK9 inhibitors for ACS patients. ⋯ Although this study demonstrates that PCSK9 inhibitors have higher drug-induced adverse events, they can not only reduce low-density lipoprotein cholesterol levels but also reduce the incidence of MACEs simultaneously. However, these findings needed to be further verified through large sample, multicenter, double-blind randomized controlled trials.

Observational Study
Investigating risk factors for medication errors during perioperative care: A retrospective cohort study.
Medication errors during perioperative care significantly compromise patient safety and the quality of outcomes. It is crucial to identify and understand the factors that contribute to these errors to develop effective, targeted interventions. This study aims to explore the risk factors associated with medication errors during perioperative care in a tertiary hospital setting, focusing on patient demographics, medication types, administration routes, and nursing care characteristics. ⋯ The presence of a dedicated anesthesia nurse significantly reduced the likelihood of errors. Patient age, medication type, administration route, nursing education level, and the involvement of specialized anesthesia nurses emerged as significant factors influencing the risk of medication errors in perioperative care. These findings underscore the need for targeted educational and procedural interventions to mitigate such errors, enhancing patient safety in surgical settings.

Observational Study
Effect of different concentrations of sufentanil combined with ropivacaine on epidural fever during labor: A single-center retrospective study.
Labor epidural analgesia (LEA) is associated with increased maternal body temperature; however, the responsible mechanism is unknown. Recent studies suggest that changes in EA affect the incidence of fever and that epidural sufentanil supplementation enhances analgesia and reduces the amount of local anesthetic. The aim of this study was to evaluate the effect of different concentrations of sufentanil combined with ropivacaine on intrapartum fever during delivery. ⋯ EA may increase the risk of intrapartum epidural-associated fever. Compared with the 0.4 µg/mL sufentanil group, the 0.2 µg/mL sufentanil group can provide better analgesia and improve maternal fever. These retrospective results highlighted the importance of prospective and mechanistic studies of maternal fever associated with intraspinal analgesia.
