Objective : The aim of this study is to implement a critical pathway (CP) for patients undergoing lumbar laminectomy or microdiscectomy and describe the results before and after the CP in terms of length of hospital stay and cost. Methods : From March 2008 to February 2009, 61 patients underwent lumbar laminectomy or microdiscectomy due to stenosis or one- or two-level disc herniation in our department and were included in the prepathway group. After development and implementation of the CP in March 2009, 58 patients were applicable for the CP, and these were classified as the postpathway group. Results : The CP, which established a 6-day hospital stay (5 bed-days), was fulfilled by 42 patients (72.4%) in the postpathway group. The mean length of stay was 5.4 days in the postpathway group compared to 6.9 days in the prepathway group, demonstrating a 20% reduction, which was a statistically significant difference ($p{\leq}0.000$). There was a statistically significant reduction in charges for bed and nursing care (p=0.002). Conclusion : Implementation of a CP for lumbar laminectomy or microdiscectomy produced significant decreases in length of hospitalization and charges for bed and nursing care. We believe that this CP reduces the unnecessary use of hospital resources without increasing risk of adverse events.

Background: A clinical pathway (CP) can standardize and improve perioperative care for a number of interventions. In hepatic surgery, however, pertinent evidence is very limited. This study was conducted to implement a CP for hepatocellular carcinoma (HCC) patients undergoing hepatectomy, and to evaluate its effects on hospital costs, length of hospital stay (LOHS) and early clinical outcomes. Materials and Methods: Medical records for HCC patients undergoing hepatectomy were retrospectively reviewed before implementation of a CP (the non-CP group) from March 2012 to August 2012. This information was compared with the data collected prospectively from patients after implementation of the CP (the CP group) between September 2012 and April 2013. Hospital costs, LOHS and early clinical outcomes were evaluated and compared between groups. Results: There were no significant differences in terms of patient clinical characteristics between the two groups. For clinical outcome measures, no significant differences were found in postoperative complications, mortality and readmission rate. The hospital costs were significantly reduced from 24,844 RMB in the non-CP group to 19,761 RMB in the CP group (p<0.01). In addition, patients of the CP group also had shorter LOHS compared with the non-CP group (8.3 versus 12.3 days, p<0.001). Conclusions: The CP proved to be an effective approach to minimize hospital costs and LOHS with hepatectomy for HCC without compromising patient care.

$I{\kappa}B$, a cytoplasmic inhibitor of nuclear factor-${\kappa}B$ ($NF-{\kappa}B$), is reportedly degraded via the proteasome. However, we recently found that long-term incubation with proteasome inhibitors (PIs) such as PS-341 or MG132 induces $I{\kappa}B{\alpha}$ degradation via an alternative pathway, lysosome, which results in $NF-{\kappa}B$ activation and confers resistance to PI-induced lung cancer cell death. To enhance the anti-cancer efficacy of PIs, elucidation of the regulatory mechanism of PI-induced $I{\kappa}B{\alpha}$ degradation is necessary. Here, we demonstrated that PI up-regulates nuclear factor (erythroid-derived 2)-like 2 (Nrf2) via both de novo protein synthesis and Kelch-like ECH-associated protein 1 (KEAP1) degradation, which is responsible for $I{\kappa}B{\alpha}$ degradation via macroautophagy activation. PIs increased the protein level of light chain 3B (LC3B, macroautophagy marker), but not lysosome-associated membrane protein 2a (Lamp2a, the receptor for chaperone-mediated autophagy) in NCI-H157 and A549 lung cancer cells. Pretreatment with macroautophagy inhibitor or knock-down of LC3B blocked PI-induced $I{\kappa}B{\alpha}$ degradation. PIs up-regulated Nrf2 by increasing its transcription and mediating degradation of KEAP1 (cytoplasmic inhibitor of Nrf2). Overexpression of dominant-negative Nrf2, which lacks an N-terminal transactivating domain, or knock-down of Nrf2 suppressed PI-induced LC3B protein expression and subsequent $I{\kappa}B{\alpha}$ degradation. Thus, blocking of the Nrf2 pathway enhanced PI-induced cell death. These findings suggest that Nrf2-driven induction of LC3B plays an essential role in PI-induced activation of the $I{\kappa}B$/$NF-{\kappa}B$ pathway, which attenuates the anti-tumor efficacy of PIs.

Objectives: This study aimed to establish a linkage model involving regional responsible medical institutions after analyzing the existing conditions and deriving problems through qualitative analysis within the community care system. Methods: A total of 14 participants of this study were selected through the snowball sampling method, including 7 community care service providers and 7 service users. As for the research data, primary data were collected through interviews, and as a result of analyzing according to Aday&Anderson' model, a total of 5 catergories, 8 topics, and 22 sub theme were derived. Results: The problem derived from the interview is that division services are provided for each institution due to the absence of a key central institution of community care system, and users' commercial institutions is unclear. The second is the inconsistency between the needs and supply for community care, resulting in a possibility of delay in returning to the community after discharge. Based on these problems, it is necessary to unify it as an community care window of the Dong-community center. In addition, there is a need for public health centers to play an active role, and to establish a public-private joint system with the Health and Living Support Center to establish a model that can play a certain role. Conclusions: Therefore, based on the results of this study, it can be used as basic data when constructing community care model and applying it as an expanded model in the future.

연구배경 : Cyclosporin A(CsA)와 tacrolimus(FK506)은 현재 임상에서 널리 쓰이는 면역억제제이다. CsA와 FK506이 $I{\kappa}B/NF-{\kappa}B$ 경로에 미치는 영향에는 세포에 따라 다양한 효과가 알려져 있다. 그러나 CsA와 FK506이 기관지 상피세포에서 $I{\kappa}B/NF-{\kappa}B$ 경로에 미치는 효과에 관해서는 알려져 있지 않고, 각종 염증 세포에서의 차이에 관해서도 보고가 미미한 실정이다. 본 연구에서는 비염증세포인 기관지상피세포와, 폐의 염증에 중요한 역할을 하는 염증 세포(폐포대식세포, 단핵구, 림프구)에서 CsA와 FK506이 $I{\kappa}B{\alpha}$의 분해에 미치는 영향과 그 기전을 평가하였다. 방 법 : 비염증세포로는 BEAS-2B와 A549 세포주를 이용하였다. FK506 또는 CsA 전처치 후 TNF-${\alpha}$로 자극하고 anti-$I{\kappa}B{\alpha}$ 항체를 이용한 Western blot으로 $I{\kappa}B{\alpha}$의 분해 여부를 관찰하였다. 염증세포로는 폐포대식세포, 말초혈액 단핵구 및 림프구를 이용하였고, 역시 FK506 또는 CsA 전처치 후 TNF-${\alpha}$, IL-$1{\beta}$, LPS로 자극하고 anti-$I{\kappa}B{\alpha}$ 항체를 이용한 Western blot으로 $I{\kappa}B{\alpha}$의 분해 여부를 관찰하였다. IKK의 활성도는 GST-$I{\kappa}B{\alpha}$를 기질로 이용한 in vitro immune complex kinase assay로 평가하였다. 결 과 : 사용된 모든 세포에서 CsA와 FK506은 $I{\kappa}B{\alpha}$의 발현에 영향을 미치지 않았다. 기관지 상피세포에서 TNF-${\alpha}$ 자극에 의한 $I{\kappa}B{\alpha}$의 분해는 CsA의 전처치로 억제되었으나, FK506의 전처치로는 억제되지 않았다. 단핵구, 림프구 및 폐포대식세포에서 외부자극에 의한 $I{\kappa}B{\alpha}$의 분해는 CsA 또는 FK506의 전처치로 억제되었으나 IKK활성은 억제되지 않았다. 결 론 : CsA와 FK506은 각각 기관지 상피세포와 단핵구, 림프구, 폐포대식세포에서 외부 자극에 의한 $I{\kappa}B{\alpha}$의 분해를 억제하는데, 이는 IKK 활성화의 억제가 아닌 다른 경로를 통하는 것으로 생각된다.

Fetal growth restriction (FGR) is a prevalent obstetric condition. This study aimed to investigate the role of Toll-like receptor 9 (TLR9) in regulating the inflammatory response and gut microbiota structure in FGR. An FGR animal model was established in rats, and ODN1668 and hydroxychloroquine (HCQ) were administered. Changes in gut microbiota structure were assessed using 16S rRNA sequencing, and fecal microbiota transplantation (FMT) was conducted. HTR-8/Svneo cells were treated with ODN1668 and HCQ to evaluate cell growth. Histopathological analysis was performed, and relative factor levels were measured. The results showed that FGR rats exhibited elevated levels of TLR9 and myeloid differentiating primary response gene 88 (MyD88). In vitro experiments demonstrated that TLR9 inhibited trophoblast cell proliferation and invasion. TLR9 upregulated lipopolysaccharide (LPS), LPS-binding protein (LBP), interleukin (IL)-1β and tumor necrosis factor (TNF)-α while downregulating IL-10. TLR9 activated the TARF3-TBK1-IRF3 signaling pathway. In vivo experiments showed HCQ reduced inflammation in FGR rats, and the relative cytokine expression followed a similar trend to that observed in vitro. TLR9 stimulated neutrophil activation. HCQ in FGR rats resulted in changes in the abundance of Eubacterium_coprostanoligenes_group at the family level and the abundance of Eubacterium_coprostanoligenes_group and Bacteroides at the genus level. TLR9 and associated inflammatory factors were correlated with Bacteroides, Prevotella, Streptococcus, and Prevotellaceae_Ga6A1_group. FMT from FGR rats interfered with the therapeutic effects of HCQ. In conclusion, our findings suggest that TLR9 regulates the inflammatory response and gut microbiota structure in FGR, providing new insights into the pathogenesis of FGR and suggesting potential therapeutic interventions.

Purpose: Nursing informatics competency is used to manage and improve the delivery of safe, high-quality, and efficient healthcare services in accordance with best practices and professional and regulatory standards. This study examined the relationship between nursing informatics competency (NIC), nursing care left undone, and nurse reported quality of care (NQoC) and nursing productivity. A path model for their effects on nursing productivity among clinical nurses was also established. Methods: Data were collected using structured questionnaires answered by 192 nurses working in a tertiary hospital located in J city, Korea, and analyzed using SPSS/WIN 23.0 and AMOS 21.0 program. Results: The fit indices of the alternative path model satisfied recommended levels χ² = .11 (p = .741), normed χ² (χ² /df) = .11, SRMR = .01, RMSEA = .00, GFI = 1.00, NFI = 1.00, AIC = 18.11. Among the variables, NIC (β = .44, p < .001), NQoC (β = .35, p < .001) had a direct effect on nursing productivity. Due to the mediating effect of NQoC on the relationship between NIC and nursing productivity, the effect size was .14 (95% CI .08~.24). Meanwhile, nursing care left undone through NQoC in the relationship between NIC and nursing productivity, has a significant mediation effect (estimate .01, 95% CI .00~.03). The explanatory power of variables was 44.0%. Conclusion: Education and training for enhancing NIC should be provided to improve nursing productivity, quality of care and to reduce missed nursing care. Furthermore, monitoring the quality of nursing care and using it as a productivity index is essential.
