To compare the risk of coronary artery lesions (CAL) in children with complete and incomplete Kawasaki disease (KD) before and after immunoglobulin therapy and explore the mediation mechanisms underlying this association. All patients with KD admitted to the Wenzhou Medical University affiliated Yuying Children's Hospital were divided into complete and incomplete KD groups. The independent effect of KD type on the risk of CAL and the intermediate effect of admission time on the association between KD type and CAL were assessed. ⋯ In conclusion, the risk of CAL among patients with incomplete KD was higher than that for complete KD, especially before therapy. In patients without CAL before treatment, the risk of CAL after treatment was equivalent for the two groups. Delayed admission may be one of the important mediating mechanisms for the higher risk of CAL in incomplete KD children.

This study describes the characteristics of opioid prescriptions for pediatric patients discharged from the emergency department (ED) with acute injuries, including type, formulation, quantity dispensed, and associations with patient age group and prescriber level of training. This retrospective cohort study enrolled all acutely injured patients receiving opioid prescriptions at discharge from an urban academic pediatric ED in a 1-year period. Electronic medical records were reviewed to abstract clinical and prescription data and prescriber level of training. ⋯ Post-graduate year 2 (PGY2) residents prescribed more doses than PGY1 or PGY3+ residents. Our data show wide variation in the number of opioid doses prescribed to acutely injured pediatric patients at ED discharge and frequent use of liquid formulation; both factors may place this population at risk for accidental ingestion. These findings also support the development of pediatric clinical guidelines to define appropriate quantities of opioids to prescribe, promote poisoning prevention strategies, and design post-graduate education for medical trainees about safe prescribing practices.

Secreted frizzled-related protein 5 (SFRP5) has been reported to be downregulated in prostate cancer. However, its biological role in this malignancy has not been clarified yet. In the present study, we performed SFRP5 overexpression experiments to determine its function in prostate cancer cell growth, invasion, tumorigenesis, and docetaxel sensitivity. ⋯ SFRP5-transfected xenograft tumors showed a reduction in the percentage of Ki-67-positive proliferating cells and an increase in terminal deoxynucleotidyl transferasebiotin-dUTP nick end labeling-positive cells. These data suggest that SFRP5 overexpression suppresses the aggressive phenotype of prostate cancer cells and overcomes docetaxel resistance through inactivation of β-catenin signaling. Therefore, delivery of SFRP5 may offer therapeutic benefits in the treatment of prostate cancer.

This study aims to investigate the association between pulmonary embolism (PE) and the risk of psychiatric disorders. A total of 21,916 patients aged ≥20 years with PE between January 1, 2000, and December 31, 2015, were selected from the National Health Insurance Research Database of Taiwan, along with 65,748 (1:3) controls matched for sex and age. Cox regression model revealed the crude HR was 1.539 (95% CI 1.481 to 1.599; p<0.001), and after adjusting all the covariates, the adjusted HR was 1.704 (95% CI 1.435 to 1.991, p<0.001), for the risk of psychiatric disorders in the PE cohort. ⋯ PE was associated with the overall psychiatric disorders, dementia, anxiety, and depression, after the exclusion of the psychiatric diagnoses in the first 5 years. The patients with PE were associated with psychiatric disorders. This finding could serve as a reminder to the physicians to be more watchful and aware in the long-term follow-up of patients with PE for their care and potential mental health problems.

Anemia is common in chronic kidney disease (CKD) and may be affected by trace element concentrations. While the concentrations of trace elements are known to be altered in CKD, the relationship between trace element and hemoglobin concentrations has not been systematically investigated in a large cohort. This study aims to examine associations between trace element concentrations and anemia in patients with CKD. ⋯ The serum iron concentration was found to correlate positively with zinc, cadmium, and selenium, but negatively with copper and manganese concentrations in the total study population (all p<0.05). The associations between serum concentrations of trace elements and hemoglobin differ between patients with and without CKD. Further investigations are warranted to determine whether patients with CKD have distinct trace element requirements.
