RESUMEN
INTRODUCTION: The gain/amplification (amp) of 1q21 is one of the most common high-risk chromosome abnormality (HRCA) in multiple myeloma (MM). The prognostic value of 1q21+ remains to be controversial on the status of gain or amp and the combination of other HRCAs. METHODS: In this retrospective study, we included 318 newly diagnosed MM (NDMM) patients who had fluorescence in situ hybridization (FISH) data and treated with novel agents in our department. RESULTS: Our study noted MM patients with amp 1q21 were more likely accompanied with t(4;14), t(14;16), and t(14;20). Patients with amp 1q21 presented with elder age, advanced Revised International Staging System (R-ISS) stages, anemia, and more plasma cells in bone marrow compared to patients with gain 1q21 alone and no 1q21+. Moreover, amp 1q21 alone correlated with shorter progression-free survival (PFS) (22.8m vs. 40.5m vs. 39.6m) and overall survival (OS) (45.2m vs. NA vs. 83.5m) compared with gain 1q21 alone and no FISH abnormalities. Although the high ratio of proteasome inhibitor and immunomodulatory drugs used in patients with amp 1q21, the overall response (ORR) was the lowest compared with no 1q21+ and gain 1q21. Multivariate analysis defined amp 1q21 as an independent prognostic marker for NDMM patients, rather than gain 1q21. CONCLUSION: The amp 1q21 predict inferior treatment response and survival, especially coexisted with high-risk IgH translocation.

AIMS: To evaluate the effectiveness of the hospital-family holistic care model based on the theory of 'Timing It Right' in caregivers of patients with permanent enterostomy. DESIGN: A prospective randomized controlled trial. METHODS: One hundred and twenty-five caregivers of patients with permanent enterostomy were recruited from 1 May 2017-31 August 2019. They were randomized into either intervention group (N = 62) or control group (N = 63). The control group received routine care and follow-up, while the intervention group received routine care, follow-up, and hospital-family holistic care intervention based on 'Timing It Right'. The care ability, psychological distress, and life quality of the caregivers were evaluated between the groups before the intervention, at discharge, and 3 and 6 months after discharge. RESULTS: One hundred and eleven caregivers completed the study (88.8%). At 3 and 6 months after discharge, the care ability and life quality in the intervention group were significantly better than those in the control group (t = 8.506/9.783, t = 22.652/26.179, p < 0.05) based on the t tests, and the psychological distress was lower than that in the control group. The ostomy adaptability of the control group was significantly lower than that in the intervention group (p < 0.001) based on the t tests, and the χ2 test showed that ostomy complication was more than that in the intervention group (23.81% vs. 12.90% and 34.92% vs. 19.35%; p < 0.05) at 3 and 6 months after discharge. The interaction between time and group showed that the effect of time factor varied with the group and the four evaluation indexes in the intervention group gradually improved with the extension of the observation time and were better than those in the control group based on generalized estimating equation model. CONCLUSION: The hospital-family holistic care model based on 'Timing It Right' can effectively improve the care ability of caregivers of patients with permanent enterostomy, reduce psychological distress, and improve the quality of life. IMPACT: The caregivers of patients with permanent enterostomy showed dynamic changes in their care experience and needs at different stages of the disease. The hospital-family holistic care intervention strategy based on 'Timing It Right' can effectively improve the caregiver's care ability, alleviate psychological distress, and improve the quality of life. Additionally, improving the patients' stoma adaptability and reducing the incidence of complications related to ostomy.

AIMS: To systemically review the efficacy and safety of auricular point therapy in patients with cancer-related fatigue. DESIGN: A systematic review and meta-analysis of randomized controlled trials. DATA SOURCES: Eight electronic databases (PubMed, CENTRAL, Embase, CINAHL, Web of Science, China Biology Medicine, China National Knowledge Infrastructure and WanFang Data Knowledge Service Platform) were explored for randomized controlled trials from their inception to 1 December 2018. REVIEW METHODS: The risk of bias assessment tool was adopted in accordance with Cochrane Handbook 5.3.0. All included studies reported the effects on cancer-related fatigue as the primary outcome. Effect size was estimated using relative risk, standardized mean difference or mean difference with a corresponding 95% confidence interval. Review Manager 5.3 was used for meta-analysis. RESULTS: Six studies comprising 394 patients were included. The results of meta-analysis showed that auricular point therapy plus standard care produced more positive effects on cancer-related fatigue and quality of life than standard care alone. It could significantly improve the role, emotional, cognitive, and social functions of patients with cancer-related fatigue. CONCLUSIONS: Auricular point therapy may be a safe therapy to relieve cancer-related fatigue and enhance the quality of life of patients with cancer. However, the evidence was inconclusive due to limitations on the quantity and quality of included studies. Rigorously designed randomized controlled trials should be conducted to verify the results. IMPACT: Auricular point therapy is a simple and safe therapeutic approach that may alleviate cancer-related fatigue of common complications in patients with cancer and it is worth promoting in the community, family, and hospital. Moreover, the research findings can provide suggestions and inspiration for nurses and researchers to implement the proposal, which is conducive to design more rigorous and high-quality randomized controlled trials.
RESUMEN
AIMS AND OBJECTIVES: To explore the effects of hospital-family holistic care model based on 'Timing It Right' on the health outcome of patients with permanent colostomy. BACKGROUND: Colorectal cancer is a common malignant tumour of digestive system, which seriously threatens human life and health. Colostomy is one of the main treatments for colorectal cancer, which effectively improves the 5-year survival rate of patients. However, the postoperative psychological and physiological rehabilitation nursing is still faced with great challenges due to the change of body image and defecation pathway caused by colostomy. METHODS: A randomised controlled trial was conducted, and 119 patients with permanent enterostomy were randomly divided into two groups, with 60 cases in the intervention group and 59 cases in the control group. The intervention group received routine care follow-up and hospital-family holistic care intervention based on 'Timing It Right', while the control group received routine care and follow-up. The resilience, self-care ability, complications and life quality of patients with permanent enterostomy were compared between two groups before intervention, at discharge, 3 months and 6 months after discharge. CONSORT checklist was applied as the reporting guideline for this study (see Appendix S1). RESULTS: A total of 108 patients with permanent enterostomy completed the study (90.76%). At 3 months and 6 months after discharge, the resilience and quality of life in the intervention group were significantly better than those in the control group (t = 4.158 vs. 7.406, t = 4.933 vs. 8.611, p < .05), while the complications in the intervention group were significantly lower than that in the control group (25.5% vs. 41.51%, 14.45% vs. 30.19%; p < .05). The self-care ability of the intervention group was significantly better than that in the control group (t = 1.543 vs. 3.656 vs. 6.273, p < .05) at discharge, 3 months and 6 months after discharge. The interaction between time and grouping showed that the effect of time factor varied with the grouping. After intervention, there were significant differences in psychological resilience, self-care ability, complications and quality of life between the two groups at different observation points (p < .01). The three evaluation indices of intervention group increased with the migration of observation time points and were significantly better than those of control group, especially the quality of life (84.35 ± 4.25 vs. 60.45 ± 8.42, p < .01). CONCLUSIONS: The hospital-family holistic care model based on 'Timing It Right' can effectively improve the psychological resilience, self-care ability and quality of life; reduce complications; and improve the health outcomes of patients with permanent enterostomy. RELEVANCE TO CLINICAL PRACTICE: Patients with permanent enterostomy have different needs for nursing care at different stages of the disease, and they are dynamically changing. The hospital-family holistic care model based on 'Timing It Right' can effectively improve the health outcomes of patients with permanent enterostomy, which is worthy of clinical application.

OBJECTIVE: In this study, we aimed to investigate Bregs, their regulatory effects on Th17/Treg cell balance, and the release of downstream inflammatory factors in a mouse model of low-density lipoprotein receptor (LDLr)-/- + Pristane. METHODS: After the establishment of the mouse model of systemic lupus erythematosus (SLE) complicated with atherosclerosis (AS), 8-week-old LDLr-/- + Pristane mice (n = 10) were included in the SLE + AS group. Furthermore, 8-week-old MRL/lpr and C57 mice were used as the SLE and normal control groups, respectively (n = 10 per group). After feeding the mice a high-fat diet for 14 weeks, peripheral blood and spleen of mice were collected, and Bregs, Th17, and Treg cells and related inflammatory factors were detected by flow cytometry, enzyme-linked immunosorbent assay, and reverse-transcription polymerase chain reaction. RESULTS: The number of Bregs and Tregs in spleen lymphocytes of SLE + AS mice significantly decreased compared with the C57 group (p < .05), whereas the number of Th17 cells significantly increased (p = .000). Furthermore, the proportion of Bregs showed a negative correlation with the Th17/Treg ratio (p = .03). Mice in the SLE + AS group showed higher serum interleukin (IL)-10, IL-17, and tumor necrosis factor-α levels than those in the SLE and C57 groups (p < .05). Furthermore, IL-35 and transforming growth factor (TGF)-ß expression was reduced in the SLE + AS group compared with the C57 group (p < .05). CONCLUSIONS: The proportion of Breg decreases was negatively associated with increased Th17/Treg which was increased in SLE + AS mice, indicating that Bregs may regulate Th17/Treg cell homeostasis and cytokine release via IL-35 and TGF-ß production.

This study aimed to use the internal design of 3D food printing (3DFP) technology to obtain freeze-dried pumpkin with controllable crispness and higher shape fidelity. Two internal structural variables, namely filling pattern (honeycomb, rectilinear, grid, and triangular) and filling rate (25, 50, 75, and 100%), were studied to assess the impact on the shape fidelity and crispness characteristic of the product. As the filling rate decreased, the printing accuracy of the samples increased. Regardless of the filling patterns, the 75% filled samples exhibited the greatest deformation. The crispness of the samples was closely related to the filling pattern and filling rate. In the case of the high filling rate, the internal structure of the samples was dense. It was less likely to be broken under the action of force and the crispness was reduced. In addition, the internal structure of the sample influenced its physical properties, and the crispness customization of the product can be achieved by designing the porosity. Morphological differences between printed and cast samples suggested that 3DFP was beneficial for the processing and preparation of highly viscoelastic materials. The crispness of cast sample was obviously less than that of the 100% filled printed samples. The results opened an interesting perspective to create crisp foods with high shape fidelity that meet specific texture requirements and provide new sensory perceptions.

Objective: To use machine learning methods to explore overall survival (OS)-related prognostic factors in elderly multiple myeloma (MM) patients. Methods: Data were cleaned and imputed using simple imputation methods. Two data resampling methods were implemented to facilitate model building and cross validation. Four algorithms including the cox proportional hazards model (CPH); DeepSurv; DeepHit; and the random survival forest (RSF) were applied to incorporate 30 parameters, such as baseline data, genetic abnormalities and treatment options, to construct a prognostic model for OS prediction in 338 elderly MM patients (>65 years old) from four hospitals in Beijing. The C-index and the integrated Brier score (IBwere used to evaluate model performances. Results: The 30 variables incorporated in the models comprised MM baseline data, induction treatment data and maintenance therapy data. The variable importance test showed that the OS predictions were largely affected by the maintenance schema variable. Visualizing the survival curves by maintenance schema, we realized that the immunomodulator group had the best survival rate. C-indexes of 0.769, 0.780, 0.785, 0.798 and IBS score of 0.142, 0.112, 0.108, 0.099 were obtained from the CPH model, DeepSurv, DeepHit, and the RSF model respectively. The RSF model yield best scores from the fivefold cross-validation, and the results showed that different data resampling methods did affect our model results. Conclusion: We established an OS model for elderly MM patients without genomic data based on 30 characteristics and treatment data by machine learning.
RESUMEN
Currently, the most widely used screening methods for hyperuricemia (HUA) involves invasive laboratory tests, which are lacking in many rural hospitals in China. This study explored the use of non-invasive physical examinations to construct a simple prediction model for HUA, in order to reduce the economic burden and invasive operations such as blood sampling, and provide some help for the health management of people in poor areas with backward medical resources. Data of 9252 adults from April to June 2017 in the Affiliated Hospital of Guilin Medical College were collected and divided randomly into a training set (n = 6364) and a validation set (n = 2888) at a ratio of 7:3. In the training set, non-invasive physical examination indicators of age, gender, body mass index (BMI) and prevalence of hypertension were included for logistic regression analysis, and a nomogram model was established. The classification and regression tree (CART) algorithm of the decision tree model was used to build a classification tree model. Receiver operating characteristic (ROC) curve, calibration curve and decision curve analyses (DCA) were used to test the distinction, accuracy and clinical applicability of the two models. The results showed age, gender, BMI and prevalence of hypertension were all related to the occurrence of HUA. The area under the ROC curve (AUC) of the nomogram model was 0.806 and 0.791 in training set and validation set, respectively. The AUC of the classification tree model was 0.802 and 0.794 in the two sets, respectively, but were not statistically different. The calibration curves and DCAs of the two models performed well on accuracy and clinical practicality, which suggested these models may be suitable to predict HUA for rural setting.

Objectives: To evaluate the relationship between systemic lupus erythematosus (SLE) and the risk of retinal vasculitis (RV) using a population-based database. Methods: Using the 1997-2013 Taiwanese National Health Insurance Database, we identified newly diagnosed SLE patients between 2001 and 2012 as the SLE group. We matched the SLE group with non-SLE individuals selected from a representative one million sample of the population in a 1:20 ratio for age, sex, and the year of the index date. After adjusting for potential confounders, including urbanization of the patient's residence, the level of the payroll-related insured amount, and selected comorbidities, we examined the association between SLE and the risk of RV using the Cox proportional hazard model shown as hazard ratios (HRs) with 95% confidence intervals (CIs). Sensitivity analyses were conducted using various definitions of RV. Results: We included 11,586 patients with SLE and 231,720 matched non-SLE individuals. The mean age of the study participants was 36.7 ± 16.9 years, and the female-to-male ratio was 6.8:1. The incidence rates of RV were 56.39 cases per 100,000 person-years and 2.45 cases per 100,000 person-years, respectively. After adjusting for potential confounders, the incidence rate of RV in the SLE cohort was 22.99 times higher than that in the non-SLE cohort (56.39 vs. 2.45 per 100,000 person-years). The adjusted HR for RV in the SLE group was 23.61 (95% CI, 14.94-37.32). The results remained robust in the sensitivity analysis. Conclusion: This nationwide population-based study revealed that SLE patients had a significantly higher risk of RV than non-SLE individuals.
RESUMEN
BACKGROUND: Inflammatory response mediated by microglia plays a key role in cerebral ischemia-reperfusion injury. This study intends to probe the role of lncRNA SNHG4 in regulating the inflammatory response of the microglia during cerebral ischemia reperfusion. MATERIALS AND METHODS: Blood samples and cerebrospinal fluid samples were collected from acute cerebral infarction (ACI) patients and healthy controls. The middle cerebral artery occlusion (MCAO) models were constructed with rats. LPS induction and oxygen-glucose deprivation methods were respectively applied to simulate the activation of microglia in vitro. qRT-PCR was employed to determine the expressions of SNHG4, miR-449c-5p and related inflammatory factors in vivo and in vitro. The inflammatory responses of the microglia subject to the varied expressions of SNHG4 and miR-449c-5p were detected. Luciferase assays were conducted to verify the crosstalk involving SNHG4, miR-449c-5p and STAT6. RESULTS: Compared with the control group, the expression of SNHG4 derived from the samples of ACI patients and the microglia of MCAO group were remarkably down-regulated, but the expression of miR-449c-5p was dramatically up-regulated. Overexpression of SNHG4 and knock-down of miR-449c-5p could inhibit the expression of pro-inflammatory cytokine in the microglia and promote the expression of anti-inflammatory factors. Meanwhile, the phospho-STAT6 was up-regulated, whereas the knock-down of SNHG4 and over-expression of miR-449c-5p in microglia had the opposite effects. Luciferase assay confirmed that SNHG4 could target miR-449c-5p, while miR-449c-5p could target STAT6. CONCLUSION: SNHG4 can regulate STAT6 and repress inflammation by adsorbing miR-449c-5p in microglia during cerebral ischemia-reperfusion injury.

We aim to investigate whether a popular hand exercise could be used to improve the action of eating in patients with Alzheimer's disease (AD). A 6-month intervention was conducted in 60 patients with AD who live in a nursing home. They were divided into hand exercise and control groups. Patients of the control group maintained their daily routine. The improvement of Edinburgh Feeding Evaluation in Dementia scale in hand exercise group was significantly greater than in the control group ( P = .003). Significant differences in time of autonomous eating and time of simulated eating between patients in the hand exercise and control groups ( P < .05) were noted. The improvements in accuracy of eating action and coordination of eating action from baseline were significant in hand exercise group compared to the control group ( P = .020 and .014, respectively). Hand exercise is a safe and effective intervention to improve the feeding and eating of people with AD.

OBJECTIVE: To investigate the correlation between pro-B-type natriuretic peptide (NT-proBNP) and heart rate variability (HRV) in patients with diabetes. METHODS: HRV and NT-proBNP levels were assessed in 58 patients with diabetes.The time domain and frequency domain indices and the level of NT-proBNP were compared between patients with normal and abnormal HRV, and the correlation of HRV index and NT-proBNP was analyzed. RESULTS: The NT-proBNP level was significantly higher in patients with abnormal HRV than in those with normal HRV (320.2±88.3 vs 80.4±25.2 pg/ml, P<0.01).The level of NT-proBNP was negatively correlated with SDNN (r=-0.55, P<0.05), triangle index (r=-0.52, P<0.05), LF (r=-0.62, P<0.01), and VLF (r=-0.56, P<0.05). CONCLUSION: NT-proBNP level is correlated with HRV, and an increased NT-proBNP indicates cardiac autonomic neuropathy in diabetic patients.

INTRODUCTION: Curdione, one of the major sesquiterpene compounds from Rhizoma Curcumae, has been shown to exhibit multiple bioactive properties. In this study, we investigated the anti-platelet aggregation and antithrombotic activities of curdione with different methods both in vitro and in vivo. The purpose of the study was to explore an inhibitor of platelet aggregation, which promised to be a preventive or therapeutic agent for various vascular diseases. MATERIALS AND METHODS: Curdione was isolated from the essential oil of Curcuma wenyujin using the silica gel column chromatography method. The effects of curdione on human platelet aggregation induced by thrombin (0.3 U/ml), platelet-activating factor (PAF, 0.375 µg/ml), adenosine diphosphate (ADP, 10 µM) and arachidonic acid (AA, 0.1mg/ml) were tested in vitro, and the potential mechanisms underlying such activities were investigated. We also tested the antithrombotic effect of curdione in a tail thrombosis model. RESULTS AND CONCLUSIONS: Curdione preferentially inhibited PAF- and thrombin- induced platelet aggregation in a concentration-dependent manner (IC(50): 60-80 µM), whereas much higher concentrations of curdione were required to inhibit platelet aggregation induced by ADP and AA. Curdione also inhibited P-selectin expression in PAF-activated platelets. Moreover, curdione caused an increase in cAMP levels and attenuated intracellular Ca(2+) mobilization in PAF-activated platelets. In vivo, we also found that curdione showed significant antithrombotic activity. Therefore, we conclude that the inhibitory mechanism of curdione on platelet aggregation may increase cAMP levels and subsequently inhibit intracellular Ca(2+) mobilization. Furthermore, the effect observed in the tail thrombosis model might be explained completely by increased vasodilation. These results indicate that curdione may be one of the main bioactive constituents in Rhizoma Curcumae that removes blood stasis.
