Effects of Aromatherapy on Anxiety and Blood Pressure in Patients with Acute Coronary Syndrome: A Meta-Analysis of Randomized Controlled Trials.

Introduction: Patients with acute coronary syndrome (ACS) often experience high levels of anxiety, which can significantly impact their prognosis. However, evidence regarding anxiety reduction by aromatherapy in patients with ACS is lacking. This study aimed to investigate the effects of aromatherapy on anxiety in patients with ACS. Methods: The literature search was conducted using PubMed, CINAHL, Embase, Web of Science, Cochrane Library, and PsycINFO from their inception until February 21, 2024. Based on inclusion criteria, randomized controlled trials (RCTs) on aromatherapy in patients with ACS aged ≥ 18 years were included. The risk of bias in the included studies was assessed using the revised Cochrane risk-of-bias tool for RCTs. Results: A total of 14 studies were included in the final analysis. Aromatherapy significantly reduced anxiety among patients with ACS, with a large effect size (standardized mean difference [SMD] = -1.66, 95% confidence interval [CI]: -2.47 to -0.85). The effect on systolic blood pressure (SBP) was -0.65 (95% CI: -1.15 to -0.15), indicating a moderate effect size, whereas there was no significant effect on diastolic blood pressure. Inhalation therapy demonstrated a large effect size (SMD = -1.70, 95% CI: -2.33 to -1.08), whereas massage therapy did not show a significant effect on reducing anxiety. Discussion/Conclusions: The findings show that aromatherapy can effectively reduce anxiety and SBP in patients with ACS. In particular, inhalation therapy showed a significant effect on reducing anxiety levels. Applying aromatherapy in clinical settings to reduce anxiety among patients with ACS should be considered. However, the limited number of studies analyzed hinders a comprehensive evaluation of the effectiveness of massage therapy. Hence, further research is necessary to elucidate its potential role in reducing anxiety among patients with ACS.

Effects of aromatherapy on nausea and vomiting in patients with cancer: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: and purpose: Aromatherapy offers a low-risk solution for effectively managing common nausea and vomiting in cancer patients. This systematic review and meta-analysis aimed to assess its impact on these symptoms to facilitate practical guidelines establishment. METHODS: PubMed, Web of Science, Cochrane Library, MEDLINE, CINAHL, and Embase were searched for articles published until April 30, 2023. Inclusion criteria were randomized controlled trials (RCTs) on the effect of aromatherapy on nausea and vomiting in patients with cancer (age ≥18 years). The effect size was calculated using standardized mean differences (SMDs) with a random effects model. Subgroup analyses, meta-analysis of variance, and meta-regression were performed using the "meta" package in R version 4.0.2. Heterogeneity was assessed using I2 statistics. Sensitivity and publication bias analyses were performed; two reviewers independently assessed risk of bias using Cochrane's risk-of-bias tool 2.0. RESULTS: Twenty-five RCTs across 10 articles revealed that aromatherapy reduced overall nausea and vomiting in patients with cancer with significant efficacy (SMD = -0.81, 95 % confidence interval [CI]: -1.11 to -0.52). Furthermore, aromatherapy reduced nausea (SMD = -0.85, 95 % CI: -1.23 to -0.46) and combined nausea and vomiting (SMD = -1.08, 95 % CI: -1.68 to -0.47), but not vomiting alone (SMD = -0.24, 95 % CI: -1.03 to 0.55). Inhalation and massage yielded positive results, especially in chemotherapy-induced cases; peppermint oil was particularly successful. CONCLUSION: Our findings underscore aromatherapy's value in managing cancer treatment-associated nausea and vomiting. Conclusive evidence on aromatherapy-led nausea reduction is lacking due to limited RCTs; research is warranted for robust conclusions.

Real-World Risk of Gastrointestinal Bleeding for Direct Oral Anticoagulants and Warfarin Users: A Distributed Network Analysis Using a Common Data Model.

Background/Aims: : Early studies on direct oral anticoagulants (DOACs) reported a higher risk of gastrointestinal bleeding (GIB) compared with warfarin; however, recent studies have reported a reduced risk. Therefore, this study was designed to evaluate the risk of GIB in users of DOAC and warfarin. Methods: : Using a common data model, we investigated the comparative risk of GIB in subjects from eight hospitals who were newly prescribed DOACs or warfarin. We excluded subjects who had a prior history of GIB or had been prescribed both medications. After propensity score matching, we analyzed 3,347 matched pairs of new DOAC and new warfarin users. Results: : The risk of GIB in new DOAC users was comparable to that in new warfarin users (hazard ratio [HR], 0.95; 95% confidence interval [CI], 0.65 to 1.40; p=0.808). New DOAC users had a similar risk of GIB to new warfarin users among older patients >65 years (HR, 1.00; 95% CI, 0.69 to 1.52; p=0.997) and in older patients >75 years (HR, 1.21; 95% CI, 0.68 to 2.10; p=0.509). In addition, the risk of GIB was not significantly different between two groups according to sex. We also found that the risk of GIB in DOAC users was 26% lower in edoxaban or apixaban subgroups compared to rivaroxaban or dabigatran subgroups (HR, 0.74; 95% CI, 0.69 to 1.00; p=0.049). Conclusions: : In real-world practice, the risk of GIB in new DOAC users is comparable to that in new warfarin users. In DOAC users, the risk of GIB was lower in edoxaban or apixaban subgroups than rivaroxaban or dabigatran subgroups.

Nursing students' experiences regarding physical restraint use in long-term care facilities: A qualitative descriptive study.

BACKGROUND: Despite many harmful effects, physical restraints are still used in long-term care facilities. Most existing studies have focused on staff. Nursing students observe staff's use of restraints during gerontological nursing practicums, but there are few studies on nursing students' experiences regarding restraint use in long-term care settings. OBJECTIVE: This study aimed to explore nursing students' experiences with physical restraint use in order to enhance nursing education and improve care quality in long-term care facilities. METHODS: Using convenience sampling method, three nursing schools from three provinces were recruited. Twenty-six senior undergraduate nursing students who had taken a gerontological nursing practicum course participated in this study. A qualitative descriptive method was utilized to provide a clear account of the students' experiences. In-depth interviews were conducted using a semi-structured interview guide. Thematic analysis was used for data analysis. RESULTS: Four themes were identified, which included overuse of restraints, ambivalent response to restraints, becoming accustomed to restraints, and lack of education regarding restraints. Students frequently observed the use of various restraints, which elicited both negative and positive responses, ultimately leading to their desensitization to the overuse of restraints. They expressed a lack of knowledge and educational needs regarding restraint reduction. CONCLUSION: Nursing students encountered the overuse of various restraints, exhibited ambivalent responses, and became desensitized to this practice in long-term care facilities. They perceived a lack of education and educational needs regarding restraint reduction. This study adds important new knowledge to existing literature and provides important insights into restraint use in long-term care facilities. Future studies need to develop and evaluate educational programs for restraint-free and person-centered care targeting nursing students. Long-term care facilities should offer organizational support and implement continuous mandatory training to promote restraint-free care.

Oral chemotherapeutic agents in metastatic hormone-sensitive prostate cancer: A network meta-analysis of randomized controlled trials.

Background: Multiple oral chemotherapeutic agents for metastatic hormone-sensitive prostate cancer (mHSPC) have been developed for conjugated use with conventional androgen deprivation therapy (ADT). Several randomized controlled trials (RCTs) report significant benefits in mHSPC patients. Therefore, we compared overall survival (OS) and progression-free survival (PFS) benefits among considerable mHSPC oral chemotherapeutic agents. Materials and methods: We investigated mHSPC treatment efficacy through a systematic RCT-trial literature review (PubMed, Embase, Web of Science, the Cochrane Library, and Scopus). Two reviewers independently screened, extracted data, and assessed bias risk in duplicate. Results: We identified 18 RCTs (n = 13,509). Concerning OS, ADT + abiraterone, ADT + abiraterone + docetaxel, ADT + apalutamide, ADT + bicalutamide, ADT + darolutamide + docetaxel, ADT + enzalutamide, ADT + orteronel, and ADT + rezvilutamide were more effective than the standard of care (SOC). Comparing PFS, most treatments were more effective than SOC, excluding ADT + bicalutamide, nilutamide, flutamide, ADT + bicalutamide + palbociclib, and ADT + nilutamide. ADT + docetaxel with androgen receptor targeted agent (ARTA) triplet therapy was not among the top three treatments determined through ranking analysis. Conclusions: Novel oral chemotherapeutic agent combination therapies must replace current ADT monotherapy and ADT + docetaxel SOC. Even so, ADT + docetaxel with ARTA triplet therapy still is not the best mHSPC treatment and requires further study.

Effects of aromatherapy on depression: A meta-analysis of randomized controlled trials.

OBJECTIVE: Non-pharmacological interventions, such as aromatherapy, have been utilized for treating depression. This systematic review and meta-analysis aimed to investigate the effects of aromatherapy on depressive symptoms. METHOD: The databases of PubMed, MEDLINE, CINAHL, EMBASE, Web of Science, and the Cochrane Library were searched from May 5, 2023, to May 20, 2023. Only randomized controlled trials that implemented aromatherapy in adults aged ≥18 years were included. The standardized mean difference (SMD) was calculated, and subgroup analysis, meta-ANOVA, and meta-regression were performed for the moderator variables. RESULTS: Thirty-two clinical trials (27 studies) were included in the final analysis. Aromatherapy demonstrated a moderate effect size for reducing depressive symptoms (SMD = -0.56, 95% CI: -0.69 to -0.43). Inhalation was the most effective method of delivery and blended essential oils were more effective than lavender or other single essential oils. Aromatherapy demonstrated a moderate effect size for reducing depressive symptoms among menopausal women, patients with heart disease (coronary artery disease or acute coronary syndrome), and psychological illnesses. However, it demonstrated no effect on postpartum or pregnant women. Mean age was a significant moderator variable. CONCLUSIONS: Reliable evidence is present for the application of aromatherapy to reduce depressive symptoms, and it can be utilized effectively to decrease depressive symptoms.

Privacy-Preserving Federated Model Predicting Bipolar Transition in Patients With Depression: Prediction Model Development Study.

BACKGROUND: Mood disorder has emerged as a serious concern for public health; in particular, bipolar disorder has a less favorable prognosis than depression. Although prompt recognition of depression conversion to bipolar disorder is needed, early prediction is challenging due to overlapping symptoms. Recently, there have been attempts to develop a prediction model by using federated learning. Federated learning in medical fields is a method for training multi-institutional machine learning models without patient-level data sharing. OBJECTIVE: This study aims to develop and validate a federated, differentially private multi-institutional bipolar transition prediction model. METHODS: This retrospective study enrolled patients diagnosed with the first depressive episode at 5 tertiary hospitals in South Korea. We developed models for predicting bipolar transition by using data from 17,631 patients in 4 institutions. Further, we used data from 4541 patients for external validation from 1 institution. We created standardized pipelines to extract large-scale clinical features from the 4 institutions without any code modification. Moreover, we performed feature selection in a federated environment for computational efficiency and applied differential privacy to gradient updates. Finally, we compared the federated and the 4 local models developed with each hospital's data on internal and external validation data sets. RESULTS: In the internal data set, 279 out of 17,631 patients showed bipolar disorder transition. In the external data set, 39 out of 4541 patients showed bipolar disorder transition. The average performance of the federated model in the internal test (area under the curve [AUC] 0.726) and external validation (AUC 0.719) data sets was higher than that of the other locally developed models (AUC 0.642-0.707 and AUC 0.642-0.699, respectively). In the federated model, classifications were driven by several predictors such as the Charlson index (low scores were associated with bipolar transition, which may be due to younger age), severe depression, anxiolytics, young age, and visiting months (the bipolar transition was associated with seasonality, especially during the spring and summer months). CONCLUSIONS: We developed and validated a differentially private federated model by using distributed multi-institutional psychiatric data with standardized pipelines in a real-world environment. The federated model performed better than models using local data only.

Gemcitabine-cisplatin versus MVAC chemotherapy for urothelial carcinoma: a nationwide cohort study.

This study assessed the trends in methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) and gemcitabine-cisplatin (GC) regimens in Korean patients with metastatic urothelial carcinoma (UC) and compared the side effects and overall survival (OS) rates of the two regimens using nationwide population-based data. The data of patients diagnosed with UC between 2004 and 2016 were collected using the National Health Insurance Service database. The overall treatment trends were assessed according to the chemotherapy regimens. The MVAC and GC groups were matched by propensity scores. Cox proportional hazard analysis and Kaplan-Meier analysis were performed to assess survival. Of 3108 patients with UC, 2,880 patients were treated with GC and 228 (7.3%) were treated with MVAC. The transfusion rate and volume were similar in both the groups, but the granulocyte colony-stimulating factor (G-CSF) usage rate and number were higher in the MVAC group than in the GC group. Both groups had similar OS. Multivariate analysis revealed that the chemotherapy regimen was not a significant factor for OS. Subgroup analysis revealed that a period of ≥ 3 months from diagnosis to systemic therapy enhanced the prognostic effects of the GC regimen. The GC regimen was widely used as the first-line chemotherapy in more than 90% of our study population with metastatic UC. The MVAC regimen showed similar OS to the GC regimen but needed greater use of G-CSF. The GC regimen could be a suitable treatment option for metastatic UC after ≥ 3 months from diagnosis.

Incidence of Retinal Artery Occlusion and Related Mortality in Korea, 2005 to 2018.

Importance: It remains unclear whether comorbidities in patients with retinal artery occlusion (RAO), a rare retinal vascular disorder, differ by subtype and whether mortality is higher. Objective: To examine the nationwide incidence of clinically diagnosed, nonarteritic RAO, causes of death, and mortality rate in patients with RAO compared with that in the general population in Korea. Design, Setting, and Participants: This retrospective, population-based cohort study examined National Health Insurance Service claims data from 2002 to 2018. The population of South Korea was 49 705 663, according to the 2015 census. Data were analyzed from February 9, 2021, to July 30, 2022. Main Outcomes and Measures: The nationwide incidence of any RAO, including central RAO (CRAO; International Statistical Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10] code, H34.1) and noncentral RAO (other RAO; ICD-10 code, H34.2) was estimated using National Health Insurance Service claims data from 2002 to 2018, with 2002 to 2004 as the washout period. Furthermore, the causes of death were evaluated and the standardized mortality ratio was estimated. The primary outcomes were the incidence of RAO per 100 000 person-years and the standardized mortality ratio (SMR). Results: A total of 51 326 patients with RAO were identified (28 857 [56.2%] men; mean [SD] age at index date: 63.6 [14.1] years). The nationwide incidence of any RAO was 7.38 (95% CI, 7.32-7.44) per 100 000 person-years. The incidence rate of noncentral RAO was 5.12 (95% CI, 5.07-5.18), more than twice that of CRAO (2.25 [95% CI, 2.22-2.29]). Mortality was higher in patients with any RAO than in the general population (SMR, 7.33 [95% CI, 7.15-7.50]). The SMR for CRAO (9.95 [95% CI, 9.61-10.29]) and for noncentral RAO (5.97 [95% CI, 5.78-6.16]) showed a tendency toward a gradual decrease with increasing age. The top 3 causes of death in patients with RAO were diseases of the circulatory system (28.8%), neoplasms (25.1%), and diseases of the respiratory system (10.2%). Conclusions and Relevance: This cohort study found that the incidence rate of noncentral RAO was higher than that of CRAO, whereas SMR was higher for CRAO than noncentral RAO. Patients with RAO show higher mortality than the general population, with circulatory system disease as the leading cause of death. These findings suggest that it is necessary to investigate the risk of cardiovascular or cerebrovascular disease in patients newly diagnosed with RAO.

Effects of aerobic exercise on global cognitive function and sleep in older adults with mild cognitive impairment: A systematic review and meta-analysis.

We conducted a systematic review and meta-analysis to determine the integrated effect of aerobic exercise on cognitive function and sleep in older adults with mild cognitive impairment (MCI) and to optimize exercise methods for improving cognitive function. We searched multiple databases from January 1, 2011, to August 31, 2022, and analyzed 11 studies. Global cognitive function in older adults with MCI undergoing aerobic exercise training was significantly improved (standardized mean difference [SMD]=0.76, 95% confidence interval [CI]:0.37, 1.14), while sleep improvement was not significant (SMD= -2.07 [95% CI: -6.76, 2.62]). In the moderator analysis, aerobic exercise types with cognitive factors, exercise time of 30-50 min per session, and exercise frequency of 5-7 times per week had statistically significant effects on cognitive function improvement. However, meta-regression identified only exercise frequency as a significant moderator of the mean effect size of cognitive function.

Effects of a Comprehensive Person-Centered Care Education Program for Nursing Students.

Background and Objectives: The aim of this study is to develop and implement a comprehensive person-centered care (PCC) education program for nursing students and assess its effects on individualized care, empathy, communication competence, and clinical practice stress. Materials and Methods: A non-equivalent control group non-synchronized design was used. Participants were 60 third-year nursing students undergoing clinical practicum in a nursing school. They were assigned either to the control group (29 students) or experimental group (31 students). The experimental group participated in a comprehensive PCC education program, while the control group did not. Four 65-min sessions were conducted over two weeks; each session comprised 5 min of introduction, 50 min of education, and 10 min of sharing of thoughts and training. Individualized care, empathy, communication competence, and clinical practice stress were measured. Data were collected immediately before the education program and two weeks after program completion. Results: After the education program, the experimental group showed significant improvements in individualized care, empathy, and communication competence and significantly reduced clinical practice stress compared to the control group. Conclusions: The comprehensive PCC education program is a potentially beneficial intervention for nursing students to help them practice person-centered care with confidence. Longitudinal randomized controlled trials are needed to substantiate these findings.

Association between impaired glucose metabolism and long-term prognosis at the time of diagnosis of depression: Impaired glucose metabolism as a promising biomarker proposed through a machine-learning approach.

BACKGROUND: Predicting the course of depression is necessary for personalized treatment. Impaired glucose metabolism (IGM) was introduced as a promising depression biomarker, but no consensus was made. This study aimed to predict IGM at the time of depression diagnosis and examine the relationship between long-term prognosis and predicted results. METHODS: Clinical data were extracted from four electronic health records in South Korea. The study population included patients with depression, and the outcome was IGM within 1 year. One database was used to develop the model using three algorithms. External validation was performed using the best algorithm across the three databases. The area under the curve (AUC) was calculated to determine the model's performance. Kaplan-Meier and Cox survival analyses of the risk of hospitalization for depression as the long-term outcome were performed. A meta-analysis of the long-term outcome was performed across the four databases. RESULTS: A prediction model was developed using the data of 3,668 people, with an AUC of 0.781 with least absolute shrinkage and selection operator (LASSO) logistic regression. In the external validation, the AUCs were 0.643, 0.610, and 0.515. Through the predicted results, survival analysis and meta-analysis were performed; the hazard ratios of risk of hospitalization for depression in patients predicted to have IGM was 1.20 (95% confidence interval [CI] 1.02-1.41, p = 0.027) at a 3-year follow-up. CONCLUSIONS: We developed prediction models for IGM occurrence within a year. The predicted results were related to the long-term prognosis of depression, presenting as a promising IGM biomarker related to the prognosis of depression.

Effects of Exercise on Positive Symptoms, Negative Symptoms, and Depression in Patients with Schizophrenia: A Systematic Review and Meta-Analysis.

This study was performed to evaluate the effects of exercise on positive and negative symptoms and depression in patients with schizophrenia through a systematic review and meta-analysis focusing on randomized controlled trials (RCTs). PubMed, Embase, CINAHL, MEDLINE, Cochrane Library, PsycINFO, and Web of Science were searched from their inception to 31 October 2022. We also conducted a manual search using Google Scholar. This meta-analysis was conducted according to the PRISMA guidelines. The methodological quality of the studies was assessed using the Cochrane risk-of-bias tool for randomized trials. To identify the cause of heterogeneity, subgroup analysis, meta-ANOVA, and meta-regression analyses were performed as moderator analyses. Fifteen studies were included. The meta-analysis (random-effects model) for overall exercise showed a medium significant effect (standardized mean difference [SMD] = -0.51, 95% confidence interval [CI]: -0.72 to -0.31) on negative symptoms, a small significant effect (SMD = -0.24, 95% CI: -0.43 to -0.04) on positive symptoms, and a nonsignificant effect (SMD = -0.87, 95% CI: -1.84 to 0.10) on depression. Our findings demonstrate that exercise can relieve the negative and positive symptoms of schizophrenia. However, the quality of some included studies was low, limiting our results for clear recommendations.

Nursing students' experiences and perceptions of barriers to the implementation of person-centred care in clinical settings: A qualitative study.

AIM: This study aimed to explore the barriers to implementing person-centred care based on nursing students' experiences during clinical practice. DESIGN: This is a descriptive, qualitative study. METHODS: Seventeen nursing students were recruited through purposeful sampling from two universities in South Korea. The semi-structured interviews consisting of open-ended questions were conducted. The collected data were analysed using an inductive content analysis method. RESULTS: Five main categories were identified from nursing students' experiences: busyness, educational challenges, lack of awareness, lack of relationship building and lack of a policy approach.

Effects of exercise therapy on global cognitive function and, depression in older adults with mild cognitive impairment: A systematic review and meta-analysis.

BACKGROUND: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to identify the integrated effects of exercise therapy on global cognitive function and, depression in older adults with mild cognitive function (MCI) and to determine the optimal exercise methods. METHODS: We searched international, and domestic databases from January 1, 2010, to May 31, 2022, and included 22 articles in the meta-analysis (global cognitive function 21 articles; depression 7articles). Meta-analysis of variance and meta-regression were performed with moderator analysis to explore the causes of heterogeneity RESULTS: The mean effects (standardized mean differences) were 0.65 (95% confidence interval [CI]: 0.39-0.91) for global cognitive function and -0.38 (95% CI: -0.63 to -0.12) for depression in older adults with MCI who received exercise therapy, and the effect was statistically significant. CONCLUSION: Aerobic and resistance exercises were effective in improving global cognitive function, Whereas multicomponent and neuromotor exercises were not. Aerobic exercise was the most effective at improving cognitive function. Thus, exercise therapy is effective in reducing depression in older adults with MCI. The mean effect of global cognitive function increased with higher exercise frequency.

Effects of Aromatherapy on Cancer Patients' Sleep and Fatigue: A Systematic Review and Meta-Analysis.

Objective: This study aims at investigating the effectiveness of aromatherapy in enhancing sleep quality and reducing fatigue among cancer patients based on randomized controlled trials (RCTs) with a high level of evidence. Design: A systematic review and meta-analysis. Methods: Two reviewers screened and reviewed the full texts of search results obtained from six English databases and four Korean databases, and they extracted data from the selected studies independently. Risk of bias (RoB) was assessed using the revised Cochrane RoB tool for randomized trials. The review protocol was registered with the International Prospective Register of Systematic Reviews (CRD42021277515). Results: Eleven RCTs were included in this study. Aromatherapy significantly improved sleep quality among cancer patients compared with those in the control groups (routine care, no intervention, and placebo) (standardized mean difference [SMD] = -0.92, 95% confidence interval [CI]: -1.39 to -0.46; p < 0.001, I2 = 89%). However, aromatherapy did not significantly reduce fatigue among such patients (SMD = -0.40, 95% CI: -0.81 to 0.01). The results of the meta-regression confirmed that increased intervention sessions resulted in the enhanced effectiveness of aromatherapy in improving sleep quality among cancer patients (Z = -3.86, p < 0.001). Conclusion: This study showed that aromatherapy significantly improves sleep quality among cancer patients. However, aromatherapy does not significantly reduce fatigue among cancer patients. It is possible that the statistical power of the meta-analysis was weak due to the small number of included studies. Therefore, in future studies, the effects of aromatherapy on fatigue among cancer patients should be assessed further using a larger number of included studies. Further, the effects of aromatherapy should be evaluated with a focus on specific subsets of patients, such as specific cancer diagnoses and specific modalities for cancer treatment.

Neoadjuvant versus adjuvant chemotherapy in upper tract urothelial carcinoma: A nationwide cohort study.

PURPOSE: This study aimed to evaluate the trend of adjuvant chemotherapy (AC) and neoadjuvant chemotherapy (NAC) in patients who underwent radical nephroureterectomy with bladder cuff excision (NUx) for upper tract urothelial carcinoma (UTUC) to compare the perioperative outcomes and overall survival (OS) between AC and NAC using nationwide population-based data. MATERIALS AND METHODS: We collected data on patients diagnosed with UTUC and treated with NUx between 2004 and 2016 using the National Health Insurance Service database, and evaluated the overall treatment trends. The AC and NAC groups were propensity score-matched. Cox proportional hazard and Kaplan-Meier analyses were used to assess survival. RESULTS: Of the 8,705 enrolled patients, 6,627 underwent NUx only, 94 underwent NAC, and 1,984 underwent AC. The rate of NUx without perioperative chemotherapy increased from 70.8 to 78.2% (R2 = 0.632; p < 0.001). The rates of dialysis (p = 0.398), TUR-BT (p = 1.000), and radiotherapy (p = 0.497) after NUx were similar. In the Kaplan-Meier curve, the NAC and AC groups showed no significant difference (p = 0.480). In multivariate analysis, treatment with AC or NAC was not associated with OS (hazard ratio 0.83, 95% confidence interval 0.49-1.40, p = 0.477). CONCLUSION: The use of NUx without perioperative chemotherapy has tended to increase in South Korea. Dialysis, TUR-BT, and radiotherapy rates after NUx were similar between the NAC and AC groups. There was no significant difference in OS between the NAC and AC groups. Proper perioperative chemotherapy according to patient and tumor conditions should be determined by obtaining more evidence of UTUC.

The Factors Associated with Person-Centered Care Competence among Nursing Students.

To improve person-centered care (PCC) competence among nursing students, various associated factors must be considered. This study aimed to identify the factors influencing PCC competence among South Korean nursing students, using a descriptive, cross-sectional design. Participants were recruited from three nursing colleges in South Korea using convenience sampling. Data were collected from 1 December 2020 to 31 January 2021, using structured self-report questionnaires. Demographic information, positive psychological capital, ego-resiliency, and depression of the participants were assessed. Descriptive statistics, independent t-tests, one-way analyses of variance, and hierarchical multiple regression analysis were used in statistical analysis. Participants with highly positive psychological capital (r = 0.509, p < 0.001) and high ego-resiliency (r = 0.480, p < 0.001) had very good PCC competence. The multiple regression analysis revealed that 30.1% of the variance in PCC competence is attributable to positive psychological capital and ego-resiliency (F = 34.59, p < 0.001, adjusted R2 = 0.301). These results highlighted the need for strategies to enhance psychological factors, such as positive psychological capital and ego-resiliency, that could boost PCC competence in nursing students.

Neoadjuvant versus adjuvant chemotherapy in bladder cancer: a nationwide cohort study.

PURPOSE: Radical cystectomy is the standard of care for muscle-invasive bladder cancer. However, the 5-year survival rate is only about 50%. Therefore, additional treatments are needed. We compared the perioperative outcomes, overall survival, and treatment trends in patients with bladder cancer who underwent radical cystectomy and either neoadjuvant or adjuvant chemotherapy using nationwide population-based data. MATERIALS AND METHODS: We collected the data of patients diagnosed with bladder cancer treated with radical cystectomy between 2004 and 2016 using the National Health Insurance Service database. We evaluated overall treatment trends. The neoadjuvant chemotherapy and adjuvant chemotherapy groups were matched by propensity score. Cox proportional hazard analysis and Kaplan-Meier analysis were used to assess survival. RESULTS: Of 6134 patients, 1379 underwent adjuvant chemotherapy and 389 underwent neoadjuvant chemotherapy. The utilization rate of neoadjuvant chemotherapy increased from 6.4 to 12.2% from 2004 to 2016 (p = 0.018). The administration rate and number of granulocyte colony-stimulating factor cycles were lower in the neoadjuvant chemotherapy group than in the adjuvant chemotherapy group (p < 0.001 and p = 0.027, respectively). After propensity score matching, the neoadjuvant chemotherapy group had significantly better overall survival than the adjuvant chemotherapy group (p = 0.004). In multivariate analysis, neoadjuvant chemotherapy was associated with better overall survival (hazard ratio 0.77, 95% confidence interval 0.65-0.92, p = 0.003). CONCLUSIONS: Neoadjuvant chemotherapy was associated with lower granulocyte colony-stimulating factor administration and better overall survival than adjuvant chemotherapy. Neoadjuvant chemotherapy should be considered for patients with bladder cancer who undergo radical cystectomy.
