Comparative StudyComparison of Operator Workloads Associated with the Single-unit Anyfusion® Pump and the Changeover from a Syringe Pump to an Infusion Pump.
A changeover from a syringe pump to an infusion pump may transiently interrupt drug administration and result in medication errors. A newly developed infusion device (Anyfusion®) that combines the functions of an infusion pump and a syringe pump in a single unit was recently commercialized. This study compared the operator workloads associated with the Anyfusion® pump and with the conventional method using two infusion devices (a syringe pump and an infusion pump). ⋯ The introduction of Anyfusion® lessened the workload of practitioners required by the changeover process, which might reduce the risk of medication errors and subsequent patient harm.

Amplification of Stem Genes: New Potential Metastatic Makers in Patients with an Early Form of Breast Cancer.
According to our previous studies, the presence of amplifications of stem genes can lead to their ectopic expression and this is associated with an increased activity of tumor stem cells in these patients. This leads to a high aggressiveness of the tumor and the development of metastatic disease. The aim was to evaluate the prognostic significance of the presence of amplifications of stem genes and their expression in patients with early breast cancer (BC). ⋯ Our studies have shown that the presence of clones with two or more amplifications of stem gene in patients with BC T₁NxM₀ has a significant prognostic value and determines an unfavorable prognosis for distant metastasis.

Molecular Epidemiology of Staphylococcus aureus in Skin and Soft Tissue Infections and Bone and Joint Infections in Korean Children.
Community acquired-methicillin resistant Staphylococcus aureus (MRSA) clones, including ST1, ST8, and ST30 are reported worldwide. However, data among Korean children are limited. Thus, we investigated the molecular characteristics of S. aureus among children in Korea. ⋯ Molecular epidemiology of S. aureus in Korean children with SSTI and bone and joint infection showed that ST30 was predominant and mostly MSSA. Among MRSA, ST72-SCCmec type IV was the most common strain.

Anxiety, Depression and Sleep Disturbance among Customer-Facing Workers.
Mental health problems are a growing issue among customer-facing workers. This study aimed to investigate the workers' symptoms of anxiety, depression, and sleep disturbance caused by customer complaints and the suppression of one's emotions at work. ⋯ The emotional labor demanded from customer-facing workers, incurred by facing customer complaints and suppressing one's emotions at work, was found to be significantly associated with the development of depression, anxiety, and sleep disturbance symptoms among the Korean working population.

The effects on particulate matter (PM) and ozone on health are being reported by a number of studies. The effects of these air pollutants are likely to be stronger in the elderly population, but studies in this regard are scarce. The purpose of this study was to study the effects of PM ≤ 2.5 μ and ozone on chronic health effects of the elderly population. ⋯ In our study, an increase in the number of deaths in the elderly population in accordance with the increase in the PM2.5 and ozone was found. The association found in our study could also influence socioeconomic burden. Future studies need to be performed in regards to younger population, as well as other air pollutants.
