Mice selected for a high acute inflammatory response (AIRmax) are resistant to chemically induced lung tumorigenesis, whereas the low responders (AIRmin) are susceptible. In urethane-treated mice, anti-inflammatory drugs increased the tumor incidence in AIRmax but not AIRmin mice, and an inverse correlation (P<.001) between the degree of acute inflammatory response (AIR) and lung tumorigenesis was found in an F2 (AIRmax x AIRmin) intercross population. The results provide evidence for the involvement of lung tumor modifier loci in AIR regulation and implicate AIR quantitative trait loci in the inherited predisposition to lung cancer.

Troponin is a highly specific biomarker for myocardial injury. It plays a critical role in the diagnosis of acute coronary syndrome (ACS). However, elevated troponin levels are not exclusively due to cardiac ischemia and may be observed in many non-cardiac conditions, including inflammatory myopathies.

Aims: We aim to explore the predictive value of admission blood glucose to serum albumin ratio (AAR) for futile recanalization after successful interventional recanalization of acute cerebral infarction.

Methods: We retrospectively collected the data of patients suffered from acute cerebral infarction due to anterior circulation large vessel occlusion and received successful interventional recanalization from January 2019 to November 2023. Statistical analysis of clinical data was conducted using SPSS 26.

Background: Ketamine is a promising drug for analgesia in emergency medicine, but a high rate of side effects is a barrier to whispered usage. We hypothesized that ketamine bolus followed by ketamine infusion would provide a more even and longer duration of analgesia and lower rates of side effects in comparison to bolus-only administration.

Methods: This was a double-blinded, clinical trial.

Background: Falls in hospitalized patients are a serious problem, resulting in physical injury, secondary complications, impaired activities of daily living, prolonged hospital stays, and increased medical costs. Establishing a fall prediction scoring system to identify patients most likely to fall can help prevent falls among hospitalized patients.

Objectives: This study aimed to identify predictive factors of falls in acute care hospital patients, develop a scoring system, and evaluate its validity.

Transcatheter aortic valve replacement (TAVR) has become a viable treatment option for patients with severe aortic stenosis among all risk subsets. As TAVR use becomes more prevalent and patients live longer with their transcatheter valve, an increasing number of these patients can be expected to present with ACS. Overall, there is a paucity of high-quality data detailing incidence, pathophysiology, and management of ACS in this subset.
