RESUMEN
The production of saffron spice results in numerous byproducts, as only 15 g of spice can be produced from 1 kg of flowers, indicating that over 90% of the saffron flower material is eventually discarded as waste. In view of this, the paper reviews current knowledge on the natural active components in saffron byproducts and their biological activities, aiming to lay a theoretical and scientific foundation for the further utilization. Saffron byproducts contain a variety of phytochemical components, such as flavonoids, anthocyanins, carotenoids, phenolic acids, monoterpenoids, alkaloids, glycosides, and saponins. The activities of saffron byproducts and their mechanisms are also discussed in detail here.

Objective: The aims of this study were to examine the symptom severity and interference among patients with lung cancer treated with PD-1 immunotherapy, explore whether those symptoms were clustered together, and identify factors associated with symptom clusters. Methods: A cross-sectional study was conducted. Data were collected by demographic and clinical characteristic questionnaires and the M.D. Anderson Symptom Inventory Lung Cancer Module. Symptom clusters were identified using exploratory factor analysis, and stepwise linear regression was applied to analyze the factors affecting the symptom clusters. Results: A total of 148 patients with lung cancer treated with PD-1 immunotherapy participated in this study. The overall symptom burdens of these patients were mainly at a mild level. The patient symptom clusters identified in this study were a general cluster, a treatment-related cluster, a pulmonary cluster, a gastrointestinal cluster, and a neural cluster. The patients' Karnofsky performance status (KPS) score (ß â= â-2.758, P â< â0.001) and having a history of chemotherapy (ß â= â4.384, P â= â0.001) were significant predictors of the general cluster. Their KPS scores (ß â= â-1.202, P â< â0.001) and having a history of chemotherapy (ß â= â-1.957, P â= â0.001) were significant predictors of the pulmonary cluster. Their monthly income (ß â= â-0.316, P â= â0.030) and KPS scores (ß â= â-0.357, P â= â0.045) were significant predictors of the gastrointestinal cluster. Having a history of chemotherapy (ß â= â1.868, P â< â0.001) was the predictor of the neural cluster. Conclusions: The symptom burdens of patients with lung cancer and treated with PD-1 immunotherapy were at a mild level and appeared to be clustered. In addition, because the symptoms that comprise a cluster are interrelated, the diagnosis and management of each symptom in a cluster should not be performed in isolation, and each symptom in a cluster should be treated either simultaneously or in an orderly manner.
RESUMEN
Evaluating the resolution of parents of ill children can help in taking measures to alleviate their distress in a timely manner and promote children's rehabilitation. This study aims to develop and validate a nomogram for predicting the unresolved risk of parents of adolescents with psychiatric diagnoses. The data for 130 parents (modeling dataset = 90; validation dataset = 40) were collected. A nomogram was first developed to predict the unresolved risk for parents based on the logistic regression analysis in the modeling dataset. The internal and external validation then were conducted through quantifying the performance of the nomogram with respect to discrimination and calibration, respectively, in the modeling and validation datasets. Finally, the clinical use was evaluated through decision curve analyses (DCA) in the overall dataset. In the results, the nomogram consisted of six risk factors and provided a good discrimination with areas under the curve of 0.920 (95% CI, 0.862-0.978) in internal validation and 0.886 (95% CI, 0.786-0.986) in external validation. The calibration with good consistency between the observed probability and predicted probability was also found in both internal and external validation. DCA showed that the nomogram had a good clinical utility. In conclusion, the proposed nomogram exhibited a favorable performance with regard to its predictive accuracy, discrimination capability, and clinical utility, and, thus, can be used as a convenient and reliable tool for predicting the unresolved risk of parents of children with psychiatric diagnoses.
RESUMEN
AIM: To comprehensively assess the current level and identify associated factors of intention to response and emergency preparedness of clinical nurses during COVID-19 outbreak. DESIGN: A cross-sectional study was designed. METHODS: Demographic and characteristic questionnaire, intention to response scale, emergency preparedness scale and a self-designed questionnaire related to effects of events and intention to leave were used in this study. RESULTS: The mean scores of intention to response and emergency preparedness were 82.00 (SD = 18.17) and 64.99 (SD = 12.94), respectively. Moral consideration, engaged in COVID-19 protection training, had working experience in SARS, and the other eight factors were explained 34.6% of the total model variance in intention to response model (F = 80.05, p < .001). While, the level of IR, whether the pace of work was affected and above three same factors were explained 21.5% of the total model variance (F = 91.05, p < .001). Pathway analysis revealed that moral consideration, intention to leave and impacts on work and life mediate the relationship between EP and IR.

BACKGROUND: Lower work readiness is tied to anxiety, high turnover and nurse transition failure. An assessment of work readiness is necessary. To date, no relative scale exists in China. Thus, a work readiness related scale is urgently needed. OBJECTIVES: To assess the psychometric properties of the scale, and look into the status of Chinese graduate nurse work readiness and factors associated with work readiness. DESIGN, SETTINGS, AND PARTICIPANTS: Both psychometric assessment and associated factors are designed with cross-sectional studies. 832 and 435 graduate nurses were recruited in the above two studies, respectively. METHODS: Brislin's transition model was utilized for the transition process, and a six-expert panel and preliminary survey were conducted for face validity and testing the transition version respectively. Exploratory factor analysis, confirmatory factor analysis, internal consistency reliability and test-retest reliability were applied for reliability and validity testing. Additionally, a linear regression method was carried out for analyzing influencing factors of work readiness of graduate nurses across China. RESULTS: A 37-item Chinese version scale was proven to have great psychometric qualities. Five factors were extracted by exploratory factor analysis, which can explain 68.637% of the total variance. Furthermore, the confirmatory factor analysis demonstrates the fit indices of a five factors mode: X2/df = 1.769, RMSEA = 0.067, NFI = 0.859, RFI = 0.839, IFI = 0.934, CFI = 0.933, TLI = 0.923. Intra-class correlation coefficient, Cronbach's α and Guttman Split-half were 0.805, 0.960 and 0.903, respectively. Interpersonal relationships, leadership experience, scholarship, work experience and willingness to be nurses were associated with the potential to achieve higher work readiness. CONCLUSION: The Chinese version of WRS-GN with good validity and reliability can be utilized for assessment of work readiness. Besides, improving work readiness of graduate nurses based on above five associated factors, educators and hospital managers could help graduate nurses having a smooth transition for a stable nursing workforce.

BACKGROUND: Education for asthmatic children in the outpatient department is insufficient. AIM: To evaluate the efficacy of a nurse-led education pathway, a standard education programme, on children with asthma. METHODS: One hundred and eighty participants enrolled and were randomly assigned to either the control group or the intervention group. The intervention group received predetermined step-by-step education sessions based on the self-designed education pathway, while the control group received usual care. Asthma control, health-related quality of life, and health-care utilization measures were taken at baseline and at follow-up visits between February 2016 and May 2018. RESULTS: Significantly higher scores for health-related quality of life and inhaler technique at the third-month visit and asthma control test at the sixth-month visit were seen in the intervention group. The numbers of unscheduled physician visits and school absences were lower in the intervention group than in the control group within 6 months. However, no significant differences were observed in emergency department visits and hospitalizations. CONCLUSION: The nurse-led education pathway could be considered effective for children with asthma visiting the outpatient department.

OBJECTIVE: This study explored a community nursing service mode in which respiratory nurse specialists cared for patients with chronic obstructive pulmonary disease (COPD) in a 12-week period after hospital discharge, with the aim of better preventing acute exacerbations, improving health-related quality of life (HRQOL) and reducing medical expenses in these patients. METHODS: We carried out a prospective randomized controlled study in which 68 COPD patients discharged were recruited from a general hospital in Guangzhou, China, were randomized divided into two groups. The control group underwent conventional nursing care, and the intervention group received community continuing care by respiratory nurse specialists. The observation period was 12 weeks. The results of intervention were evaluated using the Seattle Obstructive Lung Disease Questionnaire (SOLDQ) and the COPD Self-Efficacy Scale (CSES). In addition, the frequency of acute exacerbations, emergency treatments or hospitalizations, and medical expenses were recorded in the 12-week observation period. RESULTS: After six weeks, the total and subscale scores (P < 0.05) of SOLDQ and CSES significantly improved compared to the baseline ones in the intervention group. The control group had significantly higher scores in the treatment satisfaction (TS) of SOLDQ, the total score, and the weather/environment and behavioral risk factors of CSES. After 12 weeks, the total and subscale scores of SOLDQ and CSES showed a sustained and significant growth in the intervention group (P < 0.05). The control group had significantly higher scores only in the weather/environment risk factor of CSES. During the 12-week observation, the intervention group had significantly fewer acute exacerbations, emergency treatments or re-hospitalizations and significantly lower average medical expenses than the control group (P < 0.05). CONCLUSIONS: Community continuing care by respiratory nurse specialists may improve HRQOL, increase self-efficacy, reduce incidence of acute exacerbation, and lower medical expenses in patients with COPD after hospital discharge.
RESUMEN
PURPOSE: To investigate the quality of life and influence factors in patients awaiting lung transplantation. METHODS: Fifty five participants who waited for lung transplantation were enrolled and received multiple surveys including Short Form 36 Health Survey Questionnaires (SF-36), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) and Perceiving Social Support Scale (PSSS). RESULTS: The subjects awaiting lung transplant scored ranging from (23.18±37.53) to (74.57±26.02) regarding SF-36, significantly lower than norms (p<0.01); they scored (48.09±9.06) and ( 52.18±9.98) in SAS and SDS respectively, which were significant higher compared with norms (p<0.01), the patients scored (5.56±1.04) regarding social total support factor in PSSS questionnaire, and the scores of family support factor was significantly higher than that of outside family support factor (p<0.05). Single factor analysis revealed that the factors affecting quality of life included monthly family per capita income, medical cost source, dyspnea, BMI, anxiety, depression, and social support (p<0.05). Multiple factor analysis screened dyspnea (p<0.001) and depression (p<0.05) as influence factors of quality of life in patients awaiting lung transplantation. CONCLUSION: Affected by various factors, the quality of life in patients awaiting lung transplant surgery is relatively poor, among which dyspnea and depression are dominant influence factors. Therefore, clinicians should take psychological and physiological measures to effectively enhance the quality of life in patients awaiting lung transplantation.
