[Reducing False Alarms and Absent Treatments by Nurses During Resuscitation in the Emergency Department].

BACKGROUND & PROBLEMS: Medical management protocols prioritize the safety of patients during emergency resuscitation situations. According to a medical center in Taiwan statistics gathered in 2017, the unnecessary activation of resuscitation teams by new nurses because of their improper assessment of patient conditions was a significant cause of anxiety in patient relatives and source of complaints directed at the medical center. In June 2018, 18.7% of the emergency resuscitation calls in the emergency department (ED) were false alarms or absent treatment incidents. After investigation, lack of clearly stated resuscitation team member responsibilities and insufficient practical training for new nurses were primary factors associated with the high rate of false alarm/absent treatment incidents in the ED. PURPOSE: To decrease the rate of absent treatment by nurses during resuscitation from 18.7% to 0% in the ED. RESOLUTION: The assignments of emergency team members were revised, a new "Emergency app" was introduced, the assignment schedule of the emergency resuscitation team was distributed, SIM realistic education training was held, stronger team work was promoted, and a standard assignment review schedule was established and regularly monitored. RESULTS: After the introduction of the resolution measures, the false alarm / absent treatment incidents in the ED caused by ED nurses dropped from 18.7% to 0%. CONCLUSIONS: Resuscitation workflow is closely related to patient safety, and teamwork among colleagues critical to successful resuscitation. The project revised resuscitation teamwork assignments and organized resuscitation education training, including simulation courses, to enhance the understanding of team members. The strategy outlined in this paper may be used to raise awareness using posters and resuscitation record checklists to track and manage the team`s progress. This project was designed to enhance teamwork to decrease the rate of absent treatment and to provide safe and quality resuscitation care in order to improve resource management by the team to increase productivity.

Mechanism of IL-6 induced secretion of IL-10 in nasopharyngeal carcinoma CNE-2 cells / 局解手术学杂志

Objective To study the mechanism of IL-6 stimulated the secretion of IL-10 in nasopharyngeal carcinoma CNE-2 cells.Methods Nasopharyngeal carcinoma CNE-2 cells were cultured with recombination cytokine IL-6 in vitro,or anti-IL-6 receptor antibody and signal pathway inhibitor were pre-incubated for 1 hour,and then IL-6 were added,the mRNA and protein level of IL-10 were separately detected by RT-PCR and enzyme-linked immunosorbent assay.Results Compared with the control group,the expression and secretion of IL-10 in IL-6 stimulated group were significantly increased,which was in a dose and time dependent way,the difference was significant(P ＜ 0.01).Additionally,IL-6 stimulated the expression and secretion of IL-10 by CNE-2 cells were significantly decreased in following pre-incubated with anti-IL-6 receptor antibody or NF-κB inhibitor,the difference was significant(P ＜ 0.01),but such effect was not detected when CNE-2 cells were pre-incubated with the PI3K inhibitor,p38/MAPK inhibitor,JNK inhibitor,MEK1/2 inhibitor and STAT3 inhibitor.Conclusion IL-6 can induce the expression and secretion of IL-10 in nasopharyngeal carcinoma CNE-2 cells via IL-6R/NF-κB signal pathway,and blocking IL-6 signal may be useful for the immunotherapy of nasopharyngeal carcinoma.

Systematic review and meta-analysis comparing zoledronic acid administered at 12-week and 4-week intervals in patients with bone metastasis.

Zoledronic acid is used to treat patients with bone metastasis, but the optimal dosing interval remains controversial. We therefore performed a systematic review and meta-analysis to compare the efficacy and safety of a 12-week interval of zoledronic acid with the standard 4-week interval. Three randomized controlled trials comprising 2650 patients were analyzed. Using a random-effects model, pooled risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. No differences in the occurrence of skeletal-related events (SREs: RR = 0.98; 95% CI = 0.86-1.12; P = 0.80) or grade 3/4 adverse events (RR = 0.91; 95% CI = 0.69-1.20; P = 0.52) were observed between the 12-week and 4-week groups. The 12-week group tended to have lower incidences of osteonecrosis of the jaw [13 (0.98%) vs. 23 (1.73%)] and kidney dysfunction [21 (1.68%) vs. 31 (2.45%)] than the 4-week group, though the difference did not reach statistical significance (RR = 0.58, 95% CI: 0.30-1.12; P = 0.11); (RR = 0.67, 95% CI: 0.39-1.15, P = 0.15). These data show that zoledronic acid administered at 12-week intervals instead of 4-week intervals does not increase the risk of SREs, and may reduce the incidence of osteonecrosis of the jaw and kidney dysfunction. This suggests the 12-week interval with zoledronic acid may be an acceptable treatment option.

Both TALENs and CRISPR/Cas9 directly target the HBB IVS2-654 (C > T) mutation in ß-thalassemia-derived iPSCs.

ß-Thalassemia is one of the most common genetic blood diseases and is caused by either point mutations or deletions in the ß-globin (HBB) gene. The generation of patient-specific induced pluripotent stem cells (iPSCs) and subsequent correction of the disease-causing mutations may be a potential therapeutic strategy for this disease. Due to the low efficiency of typical homologous recombination, endonucleases, including TALENs and CRISPR/Cas9, have been widely used to enhance the gene correction efficiency in patient-derived iPSCs. Here, we designed TALENs and CRISPR/Cas9 to directly target the intron2 mutation site IVS2-654 in the globin gene. We observed different frequencies of double-strand breaks (DSBs) at IVS2-654 loci using TALENs and CRISPR/Cas9, and TALENs mediated a higher homologous gene targeting efficiency compared to CRISPR/Cas9 when combined with the piggyBac transposon donor. In addition, more obvious off-target events were observed for CRISPR/Cas9 compared to TALENs. Finally, TALENs-corrected iPSC clones were selected for erythroblast differentiation using the OP9 co-culture system and detected relatively higher transcription of HBB than the uncorrected cells. This comparison of using TALENs or CRISPR/Cas9 to correct specific HBB mutations in patient-derived iPSCs will guide future applications of TALENs- or CRISPR/Cas9-based gene therapies in monogenic diseases.
