It remains uncertain whether the utilization of methylprednisolone during surgery effectively mitigates the occurrence of adverse outcomes. To examine the association between perioperative methylprednisolone administration and postoperative pleural effusion and pneumonia in older patients with non-small cell lung cancer. ⋯ Perioperative methylprednisolone was associated with reducing the occurrence of postoperative pleural effusions in older patients with non-small volume lung cancer, but it was not associated with pneumonia or long-term survival outcomes.

Anesthesia can lead to functional cognitive impairment, which can seriously affect postoperative recovery. To investigate the effect and mechanism of quercetin (Que) in anesthetized rats, the study provided a new therapeutic idea for the prevention of cognitive dysfunction caused by anesthesia. ⋯ Que may inhibit ISO-induced hippocampal neuroinflammation and ameliorate functional cognitive deficits in rats by modulating miR-138-5p/ LCN2.

Observational Study
Assessment of bacterial positivity rate changes in anesthesia machine internal circuits within recovery rooms and associated risk factors.
The objective of this study is to investigate bacterial proliferation within the internal circuits of anesthesia machines in post-anesthesia care units (PACUs) following the implementation of the new protocol, where 'a single dedicated external circuit is used for each individual patient.' This measure was introduced during the COVID-19 pandemic, in alignment with a novel prevention and control strategy. ⋯ Amid the COVID-19 pandemic, characterized by the adoption of new prevention and control protocols, the disinfection interval for internal circuits of anesthesia machines in PACUs may potentially be extended. However, the emphasis of disinfection should still be placed on those anesthesia machines that have been used for a longer cumulative surgical duration and by a higher number of elderly patients over 60 years old. This approach ensures that resources are allocated effectively.

High-frequency, high-intensity transcutaneous electrical nerve stimulation (HFHI TENS, i.e. 80 Hz and 40-60 mA) is an effective, fast-acting pain relief modality after elective surgery, offering pain relief within 5 min. Few studies have explored patients' perspectives on using TENS in the post-anesthesia care unit. This study investigates patients' experiences and perceptions of TENS as a complementary approach to traditional pharmacological pain management in postoperative care. ⋯ To our knowledge, this is the first study that describes patients' views on managing postoperative pain using TENS in the post-anesthesia care unit. This study indicates that patients desire alternatives to drugs for pain control in the postoperative setting. TENS has advantages, such as a rapid onset and offset and supporting patient autonomy, as well as drawbacks, such as being ineffective when pain is too severe. TENS could be included within the routine multimodal analgesia framework for person-centred postoperative pain management.

In a low-income country, the impact of preoperative anemia on postoperative mortality among noncardiac surgery patients is little understood. As a result, we aim to investigate the association between preoperative anemia and postoperative mortality in noncardiac surgery patients in Northwest Ethiopia. ⋯ The study found that patients undergoing noncardiac surgery in Northwest Ethiopia had a higher rate of preoperative anemia than those in high-income countries. Preoperative anemia had a significant association with 28-day mortality after surgery.
