Coronary artery disease (CAD) is the most important cause of mortality and morbidity in patients who have undergone carotid artery endovascular or surgical intervention. Metabolic syndrome (MetS) and hyperhomocysteinemia (HHCY) have been reported to be associated with CAD. However, no study has investigated the association between MetS or HHCY and the severity of CAD in patients with carotid stenosis. ⋯ MetS and HHCY can predict the presence of CAD in patients with carotid stenosis. Furthermore, the MetS score and total plasma homocysteine level are significantly associated with the extent of coronary atherosclerosis.

Paraquat poisoning can be lethal, and aggressive treatments might have little or no effect on severely poisoned patients. Accordingly, a convenient prognostic test is necessary to guide therapy for acute paraquat poisoning. Sodium dithionite reduces paraquat to a blue radical form in alkaline plasma with a paraquat detection sensitivity of 2.0 mg/L, which is a 100% lethal concentration at 10 to 12 hours postingestion. The prognostic utility of this simple reaction was examined prospectively. ⋯ In this single-center study, a positive plasma dithionite test was associated with 100% mortality, despite aggressive treatment. In contrast, negative or equivocal tests were associated with a 68% survival rate. It is believed that after further verification, this test can be used to guide therapy and predict the outcomes of patients suffering acute paraquat poisoning.

Acute respiratory distress syndrome (ARDS) associated with pulmonary lipiodol embolism is a rare complication of transcatheter arterial chemoembolization (TACE). We performed a survey of ARDS associated with pulmonary lipiodol embolism after TACE. ⋯ Pulmonary lipiodol embolism after TACE can occur within a short time frame. Whether or not there is intrahepatic arteriovenous shunting detected by multidetector CT and angiography, clinicians should avoid high doses of iodized oil and carcinostatic agents. We suggest that CT should be used for the diagnosis of pulmonary lipiodol embolism.

Although past research has elucidated the principal risk factors and efficacy of preventive interventions for contrast-induced acute kidney injury (CIAKI), provider awareness of this empiric evidence base is largely unknown. We sought to assess provider knowledge of the risk factors and preventive interventions for CIAKI. ⋯ There is wide variability in providers' knowledge of CIAKI. Providers with more training on CIAKI and trainees had greater knowledge of the risk factors and preventive interventions for CIAKI. These findings underscore the need to standardize and intensify provider education of this costly and preventable iatrogenic condition.
