RESUMEN
This study was to translate the Pieper-Zulkowski pressure ulcer knowledge test (PZ-PUKT) into Traditional Chinese and evaluate its psychometric properties as well as identify the predictors of knowledge on pressure injury. The PZ-PUKT was translated into Traditional Chinese (TC-PZ-PUKT), and its content validity was evaluated. A total of 296 nurses participated in this study and completed the 72-item TC-PZ-PUKT online. The reliability of the TC-PZ-PUKT was analysed by evaluating its internal consistency and test-retest reliability. Hierarchical regression was used to determine factors associated with TC-PZ-PUKT scores. Content validity was achieved with a score of 0.986. Internal consistency was observed to be reliable, with a Cronbach's alpha of 0.858. The mean knowledge score on the TC-PZ-PUKT was 72.5%, with a 1-week test-retest reliability of r = 0.849. Education level, certification as a wound specialist and self-learning through reading articles, books or guidelines on pressure injury were significantly associated with TC-PZ-PUKT scores. The TC-PZ-PUKT is a valid and reliable tool. Education level, certification as a wound specialist and self-learning regarding pressure injury are related to knowledge of pressure injury.

This study demonstrates cellulose acetate (CA)-coated screen-printed carbon electrodes (SPCEs) for soil microbial activity detection. A capacitive sensor design utilizes a coated CA layer for effective insulation in electrolytes, eliminating the need for additional signal protection. Optimization involved comparing spin and dip coating methods, with a one-layer 10-second dip coating identified as the best balance between quality and yield. These CA/SPCEs exhibited remarkable stability over a month, suggesting their potential for long-term use in monitoring agricultural soils. Analysis of CA/SPCE profile and thickness provided insights into surface characteristics and the impact of the CA coating on electrode roughness. ATR-FTIR analysis, along with capacitive sensing, demonstrated superior sensitivity and precision for monitoring CA film degradation compared to mechanical gauges. Chemical degradation studies suggest CA's potential immunity in near-neutral environments, while enzymatic degradation investigations revealed dominance by enzymes, particularly in the initial stages. The CA/SPCE sensor responds to both enzymatic and chemical degradation, potentially serving as an indicator of total soil microbial activity. Soil experiments explored CA/SPCE with Cap-S for microbial activity sensing. Significant differences in the long-term degradation rate were observed in mycorrhizal fungi-enriched soil compared to controls, highlighting microbial influences. This study underscores the adaptability and versatility of this technology, particularly for assessing C-cycle microbial activity in agricultural fields.

BACKGROUND: Circumcision-a common pediatric procedure-can cause significant pain and anxiety. Virtual reality has been proposed as a nonpharmacological intervention to alleviate these negative experiences. OBJECTIVE: This systematic review and meta-analysis was conducted to evaluate the effects of virtual reality interventions on pain and anxiety in children undergoing circumcision. METHODS: This study comprehensively searched PubMed, Embase, and Cochrane Library for articles published from database inception to October 2, 2023. Randomized controlled trials that investigated the effects of virtual reality interventions on pain and anxiety during circumcision in children were included. The Cochrane risk-of-bias tool was used to appraise the included studies. The primary outcomes were pain and anxiety scores. RESULTS: Three randomized controlled trials and four data sets involving a total of 224 children were included in our meta-analysis. Virtual reality interventions significantly reduced children's pain and anxiety scores. CONCLUSIONS: Virtual reality interventions are promising nonpharmacological strategies for alleviating children's pain and anxiety during circumcision. Pediatric healthcare professionals use virtual reality interventions to create a child-friendly and healthy healthcare environment.
RESUMEN
BACKGROUND: Pancreatic cancer (PanCa), ranked as the 4th leading cause of cancer-related death worldwide, exhibits an dismal 5-year survival rate of less than 5â¯%. Chronic pancreatitis (CP) is a known major risk factor for PanCa. Brusatol (BRT) possesses a wide range of biological functions, including the inhibition of PanCa proliferation. However, its efficacy in halting the progression from CP to pancreatic carcinogenesis remains unexplored. METHODS: We assess the effects of BRT against pancreatic carcinogenesis from CP using an experimentally induced CP model with cerulein, and further evaluate the therapeutic efficacy of BRT on PanCa by employing Krastm4TyjTrp53tm1BrnTg (Pdx1-cre/Esr1*) #Dam/J (KPC) mouse model. RESULTS: Our finding demonstrated that BRT mitigated the severity of cerulein-induced pancreatitis, reduced pancreatic fibrosis and decreased the expression of α-smooth muscle actin (α-SMA), which is a biomarker for pancreatic fibrosis. In addition, BRT exerted effects against cerulein-induced pancreatitis via inactivation of NLRP3 inflammasome. Moreover, BRT significantly inhibited tumor growth and impeded cancer progression. CONCLUSIONS: The observed effect of BRT on impeding pancreatic carcinogenesis through targeting NLRP3 inflammasome suggests its good potential as a potential agent for treatment of PanCa.

AIM: To assess the efficacy of artificial natural light in preventing incident myopia in primary school-age children. METHODS: This is a prospective, randomized control, intervention study. A total of 1840 students from 39 classes in 4 primary schools in Foshan participated in this study. The whole randomization method was adopted to include classes as a group according to 1:1 randomized control. Classrooms in the control group were illuminated by usual light, and classrooms in the intervention group were illuminated by artificial natural light. All students received uncorrected visual acuity and best-corrected visual acuity measurement, non-cycloplegic autorefraction, ocular biometric examination, slit lamp and strabismus examination. Three-year follow-up, the students underwent same procedures. Myopia was defined as spherical equivalent refraction ≤ -0.50 D and uncorrected visual acuity <20/20. RESULTS: There were 894 students in the control group and 946 students in the intervention group with a mean±SD age of 7.50±0.53y. The three-year cumulative incidence rate of myopia was 26.4% (207 incident cases among 784 eligible participants at baseline) in the control group and 21.2% (164 incident cases among 774 eligible participants at baseline) in the intervention group [difference of 5.2% (95%CI, 3.7% to 10.1%); P=0.035]. There was also a significant difference in the three-year change in spherical equivalent refraction for the control group (-0.81 D) compared with the intervention group [-0.63 D; difference of 0.18 D (95%CI, 0.08 to 0.28 D); P<0.001]. Elongation of axial length was significantly different between in the control group (0.77 mm) and the intervention group [0.72 mm; difference of 0.05 mm (95%CI, 0.01 to 0.09 mm); P=0.003]. CONCLUSION: Artificial natural light in the classroom of primary schools can result in reducing incidence rate of myopia during a period of three years.
RESUMEN
BACKGROUND: Previous studies show that using 12-lead electrocardiogram (ECG) or 24-h ECG monitor for the detection of cardiac arrhythmia events in patients with stroke or syncope is ineffective. HYPOTHESIS: The 14-day continuous ECG patch has higher detection rates of arrhythmias compared with conventional 24-h ECG monitoring in patients with ischemic stroke or syncope. METHODS: This cross-sectional study of patients with newly diagnosed ischemic stroke or syncope received a 24-h ECG monitoring and 14-day continuous cardiac monitoring patch and the arrhythmia events were measured. RESULTS: This study enrolled 83 patients with ischemic stroke or syncope. The detection rate of composite cardiac arrhythmias was significantly higher for the 14-day ECG patch than 24-h Holter monitor (69.9% vs. 21.7%, p = .006). In patients with ischemic stroke, the detection rates of cardiac arrhythmias were 63.4% for supraventricular tachycardia (SVT), 7% for ventricular tachycardia (VT), 5.6% for atrial fibrillation (AF), 4.2% for atrioventricular block (AVB), and 1.4% for pause by 14-day ECG patch, respectively. The significant difference in arrhythmic detection rates were found for SVT (45.8%), AF (6%), pause (1.2%), AVB (2.4%), and VT (9.6%) by 14-day ECG patch but not by 24-h Holter monitor in patients with ischemic stroke or syncope. CONCLUSIONS: A 14-day ECG patch can be used on patients with ischemic stroke or syncope for the early detection of AF or other cardiac arrhythmia events. The patch can be helpful for physicians in planning medical or mechanical interventions of patients with ischemic stroke and occult AF.

Background: Double inferior vena cava (DIVC) is a rare vascular malformation. With advances in radiological techniques and diagnosis, more and more types of DIVC were identified and diagnosed. Recognition of the variety of DIVC seen on imaging is essential for subsequent venous interventions. Case presentation: A 77-year-old man presented with low back pain with left lower limb pain for 1 month. Scattered petechiae above the skin surface on the left lower leg, especially on the extensor surface, with flaking and mild tingling of the skin, were noted 3 weeks ago. Ultrasound revealed deep vein thrombosis (DVT) in the left lower limb. Computed tomography pulmonary angiography (CTPA) suggested no significant thrombus in the pulmonary artery. Computed tomography venography (CTV) of bilateral lower limbs showed that iliac vein compression syndrome with formation of deep and superficial venous traffic branches in bilateral lower limbs, predominantly on the left side. CTV of the inferior vena cava (IVC) suggested that the left common iliac vein crossed the common iliac artery bifurcation from dorsal to ventral and continued to travel cranially as a ventral vessel, and connected with the ventral IVC anterior to the right common iliac artery. The right common iliac vein extended cephalad as a dorsal vessel, which was narrowed at the level of 4th lumbar vertebra by compression of the hyperplastic bone and the osteophyte. The patient was discharged after right and left common iliac vein angiography and balloon dilation of bilateral common iliac vein. Conclusion: The formation of both ventrally and dorsally aligned DIVC is rarer. It should be clarified the effects of DIVC on DVT formation, and the importance of imaging for preoperative planning.
RESUMEN
With the busy pace of modern life, an increasing number of people are afflicted by lifestyle diseases. Going directly to the hospital for medical checks is not only time-consuming but also costly. Fortunately, the emergence of rapid tests has alleviated this burden. Accurately interpreting test results is extremely important; misinterpreting the results of rapid tests could lead to delayed medical treatment. Given that URS-10 serve as a rapid test capable of detecting 10 distinct parameters in urine samples, the results of assessing these parameters can offer insights into the subject's physiological condition. These parameters encompass aspects such as metabolism, renal function, diabetes, urinary tract disorders, hemolytic diseases, and acid-base balance, among others. Although the operational procedure is straightforward, the variegated color changes exhibited in the outcomes of individual parameters render it challenging for lay users to deduce causal factors solely from color variations. Moreover, potential misinterpretations could arise due to visual discrepancies. In this study, we successfully developed a cloud-based health checkup system that can be used in an indoor environment. The system is used by placing a URS-10 test strip on a colorimetric board developed for this study, then using a smartphone application to take images which are uploaded to a server for cloud computing. Finally, the interpretation results are stored in the cloud and sent back to the smartphone to be checked by the user. Furthermore, to confirm whether the color calibration technology can eliminate color differences between different cameras, and also whether the colorimetric board and the urine test strips can perform color comparisons correctly in different light intensity environments, indoor environments that could simulate a specific light intensity were established for testing purposes. When comparing the experimental results to real test strips, only two groups failed to reach an identification success rate of 100%, and in both of these cases the success rate reached 95%. The experimental results confirmed that the system developed in this study was able to eliminate color differences between camera devices and could be used without special technical requirements or training.
RESUMEN
BACKGROUND: Paroxetine therapy has been used for treatment of patients with depression and Parkinson's disease (dPD) in many clinical studies, but, the effects of paroxetine in dPD patients are not completely understood. The aim of this study was to systematically evaluate the effects of paroxetine therapy on depressive symptom and motor function in the treatment of dPD, in order to confer a reference for clinical practice. METHODS: Randomized controlled trials (RCTs) of paroxetine for dPD published up to October, 2022 were retrieved. Standardised mean difference (SMD), odds ratio (OR), and 95% confidence interval (CI) were calculated and heterogeneity was measured with the I2 test. The outcomes of interest were as follows: the efficacy, Hamilton depression rating scale score, unified Parkinson's disease rating scale score, Hamilton anxiety rating scale score or adverse events. RESULTS: Thirty-four RCTs with 2819 participants were included. Compared with control group, the pooled effects of paroxetine therapy on depression were (22 trials; OR 3.62, 95% CI 2.63 to 4.98, Pâ <â .00001) for antidepressant response (25 trials; SMD -2.14, 95% CI -2.73 to -1.56, Pâ <â .00001) for Hamilton depression rating scale score, the pooled effects of paroxetine therapy on motor function were (10 trials; OR 4.63, 95% CI 3.15 to 6.79, Pâ <â .00001) for anti-PD efficacy (18 trials; SMD -2.02, 95% CI -2.48 to -1.55, Pâ <â .00001) for total unified Parkinson's disease rating scale score. The Hamilton anxiety rating scale score showed significant decrease in the paroxetine treatment group compared to control group (10 trials; SMD -1.93, 95% CI -2.65 to -1.22, Pâ <â .00001). In addition, paroxetine therapy reduced the number of any adverse events obviously in dPD patients (twenty trials; OR 0.42, 95% CI 0.31 to 0.57, Pâ <â .00001). CONCLUSIONS: Paroxetine therapy has clinical benefits for improvement of depressive symptom and motor function in dPD patients, moreover, it is of high drug safety. Further well-designed, multi-center RCTs needed to identify these findings.

PURPOSE: Bone health and body composition share several common mechanisms like oxidative stress and inflammation. Anthocyanins have antioxidant and anti-inflammatory properties. We have reported that anthocyanins are associated with better body composition in children, but the associations with bone health have not been elucidated. We aimed to explore the association of anthocyanins with bone mineral content (BMC) and bone mineral density (BMD) at multiple sites in children. METHODS: In this cross-sectional study, 452 Chinese children aged 6-9 years were recruited. A validated 79-item food frequency questionnaire was used to collect dietary information. BMC and BMD at multiple sites (whole body; whole body excluding head, WBEH; limbs; arms; legs) were measured by dual-energy X-ray. RESULTS: Higher dietary intake of total anthocyanidins (per one standard deviation increase) was associated with a 1.28-13.6 g (1.31-1.60%, compared to median) higher BMC at all sites and a 3.61-6.96 mg (0.65-0.90%) higher BMD at the whole body, WBEH, and arm sites after controlling for a number of possible covariates. The results were similar and more pronounced for cyanidin, but not for delphinidin and peonidin. Higher dietary intake of cyanidin (per one standard deviation increase) was associated with a 1.33-15.4 g (1.48-1.68%) higher BMC at all sites and a 4.15-7.77 mg (0.66-1.00%) higher BMD at all sites except the legs. No statistically significant associations with BMC or BMD were found for dietary intake of delphinidin and peonidin. CONCLUSIONS: Higher dietary intake of total anthocyanidins and cyanidins were associated with higher BMC and BMD in Chinese children.

Objectives: International guidelines for managing pressure injury (PI) and ulcers recommend that family members and caregivers should be involved in making decisions for appropriate wound care. However, the effect of shared decision-making (SDM) in the context of PI remains unknown. This study investigated the efficacy of nurse-led medical SDM for PI treatment. Materials and Methods: We constructed a patient decision aid (PDA) for PI treatment on the basis of nursing evidence. Subsequently, we conducted a pilot randomized controlled trial to evaluate the efficacy of SDM compared with that of usual care (control group, [CG]) for PI treatment. Participants with stage 3, stage 4, or unstageable PI were included and randomized into two groups. In the SDM group (SDMG), 10 participants received the SDM intervention for PI before treatment. All participants were followed up for 4 weeks. Primary outcomes were measured using the nine-item SDM Questionnaire (SDM-Q-9) and Decisional Conflict Scale (DCS). Secondary outcomes included wound size and cost of wound management. Results: The expert validity (medical professors and general population) of the PDA designed for PI was measured, and the content validity index was 0.96-0.97. A total of 20 participants were enrolled (10 received SDM and 10 received usual care). The mean age of the participants was 55.7 ± 8.8 years. No significant difference in baseline characteristics (sex, age, staging, or wound area) was observed between the two groups. The SDMG had higher SDM-Q-9 (P < 0.001) and DCS (P < 0.01) scores than did the CG. For the secondary outcomes, the SDMG had a decreased change of wound size and lower wound management costs than did the CG; nevertheless, the differences were not statistically significant. Conclusion: We constructed a PDA for PI treatment, which can be applied in clinical care. The pilot test results revealed that the participants had a lower cost related wound treatment and decreasing wound size in SDMG than CG after the intervention of SDM-PI for 4 weeks. In the future, clinical studies should conduct large-scale randomized trials based on the results of this pilot study.
RESUMEN
Triple negative breast cancer (TNBC) is an aggressive cancer with very poor prognosis. Combination therapy has proven to be a promising strategy for enhancing TNBC treatment efficacy. Toosendanin (TSN), a plant-derived triterpenoid, has shown pleiotropic effects against a variety of tumors. Herein, it is evaluated whether TSN can enhance the efficacy of paclitaxel (PTX), a common chemotherapeutic agent, against TNBC. It is found that TSN and PTX synergistically suppress the proliferation of TNBC cell lines such as MDA-MB-231 and BT-549, and the combined treatment also inhibits the colony formation and induces cell apoptosis. Furthermore, this combination shows more marked migratory inhibition when compared to PTX alone. Mechanistic study shows that the ADORA2A pathway in TNBC is down-regulated by the combination treatment via mediating epithelial-to-mesenchymal transition (EMT) process. In addition, the combined treatment of TSN and PTX significantly attenuates the tumor growth when compared to PTX monotherapy in a mouse model bearing 4T1 tumor. The results suggest that combination of TSN and PTX is superior to PTX alone, suggesting that it may be a promising alternative adjuvant chemotherapy strategy for patients with TNBC, especially those with metastatic TNBC.

Self-efficacy strongly predicts clinical performance and competence. In Taiwan, there is no reliable method for assessing self-efficacy in the management of pressure injury. This study aims to establish psychometric properties of the Pressure Ulcer Management Self-Efficacy Scale (PUM-SES) translated for Taiwan and determine the validity and reliability of the Taiwanese version of the PUM-SES. Materials and methods: The PUM-SES was translated for use in Taiwan using Brislin's method. The translation's content validity, concurrent validity, predictive validity, internal consistency, and test−retest reliability were evaluated. The Pressure Ulcer Management Self-Efficacy Scale, Taiwanese version (PUM-SES-T), the Attitude toward Pressure Injury Prevention Scale (APIPS) and the Practice toward Pressure Injury Prevention Scale (PPIPS) of preventing pressure injury, and the General Self-Efficacy Scale (GSES) were tested using Pearson's correlation. A cross-sectional survey with 330 RNs in Taiwan was conducted. The PUM-SES-T was used to predict the PPIPS, and a predictive regression model was constructed considering nursing demographic variables. Results: Seven experts evaluated the PUM-SES-T with a CVI value of 0.995. An internal consistency, using Cronbach's α, of 0.762 and a test−retest reliability of 0.997 were obtained. The PUM-SES-T was positively correlated with the GSES (p < 0.001). Multiple regression revealed that the PUM-SES-T predicted practice with a strong predictive validity (F = 8.077, p < 0.001), had an adjusted R2 of 0.455, but collinearity was insignificant. In this study, PUM-SES-T is a valid instrument for intervention-related educational programs to measure self-efficacy with good reliability and validity. It can be employed when intervening in related education strategies or promoting policies.
RESUMEN
BACKGROUND: Stomal-related complications (SRCs) increase the health care burden and impair quality of life. PURPOSE: To determine the incidence rates and predictors of stomal and peristomal complications (SCs and PCs, respectively). METHODS: This was a prospective cohort study. In total, 215 patients who had undergone ostomy were enrolled and followed-up at 3, 30, 90, 180, and 360 days after surgery. During the follow-up period, SRCs were assessed by 1 colorectal surgeon and 2 wound, ostomy, and continence nurses. The SRCs were classified into SCs and PCs. RESULTS: SRCs were observed in 105 patients (48.8%). The 105 patients had 145 SRCs (66 [45.5%] SCs and 79 [54.5%] PCs). A logistic regression analysis revealed that emergency surgery (odds ratio [OR]: 2.78; P = .041), laparoscopic surgery (OR: 2.91; P = .023), and inappropriate stomal location (OR: 19.23; P < .001) were significant predictors of SCs. Inappropriate stomal location also was significantly associated with PCs (OR: 7.70; P < .001). The cumulative incidence rate of SRCs was 73% in patients who underwent stomal surgery and were followed for 360 days. CONCLUSIONS: Stomas created through emergency or laparoscopic surgery and those created at inappropriate sites were associated with a higher risk of SCs. Inappropriate stomal site was found to be a significant predictor for SCs and PCs.

Auditory verbal hallucinations (AVHs)-or hearing voices-occur in clinical and non-clinical populations, but their mechanisms remain unclear. Predictive processing models of psychosis have proposed that hallucinations arise from an over-weighting of prior expectations in perception. It is unknown, however, whether this reflects (i) a sensitivity to explicit modulation of prior knowledge or (ii) a pre-existing tendency to spontaneously use such knowledge in ambiguous contexts. Four experiments were conducted to examine this question in healthy participants listening to ambiguous speech stimuli. In experiments 1a (n = 60) and 1b (n = 60), participants discriminated intelligible and unintelligible sine-wave speech before and after exposure to the original language templates (i.e. a modulation of expectation). No relationship was observed between top-down modulation and two common measures of hallucination-proneness. Experiment 2 (n = 99) confirmed this pattern with a different stimulus-sine-vocoded speech (SVS)-that was designed to minimize ceiling effects in discrimination and more closely model previous top-down effects reported in psychosis. In Experiment 3 (n = 134), participants were exposed to SVS without prior knowledge that it contained speech (i.e. naïve listening). AVH-proneness significantly predicted both pre-exposure identification of speech and successful recall for words hidden in SVS, indicating that participants could actually decode the hidden signal spontaneously. Altogether, these findings support a pre-existing tendency to spontaneously draw upon prior knowledge in healthy people prone to AVH, rather than a sensitivity to temporary modulations of expectation. We propose a model of clinical and non-clinical hallucinations, across auditory and visual modalities, with testable predictions for future research.
RESUMEN
Wild tomatoes (Solanum peruvianum) are important genomic resources for tomato research and breeding. Development of a foreign DNA-free clustered regularly interspaced short palindromic repeat (CRISPR)-Cas delivery system has potential to mitigate public concern about genetically modified organisms. Here, we established a DNA-free CRISPR-Cas9 genome editing system based on an optimized protoplast regeneration protocol of S. peruvianum, an important resource for tomato introgression breeding. We generated mutants for genes involved in small interfering RNAs biogenesis, RNA-DEPENDENT RNA POLYMERASE 6 (SpRDR6), and SUPPRESSOR OF GENE SILENCING 3 (SpSGS3); pathogen-related peptide precursors, PATHOGENESIS-RELATED PROTEIN-1 (SpPR-1) and PROSYSTEMIN (SpProSys); and fungal resistance (MILDEW RESISTANT LOCUS O, SpMlo1) using diploid or tetraploid protoplasts derived from in vitro-grown shoots. The ploidy level of these regenerants was not affected by PEG-Ca2+-mediated transfection, CRISPR reagents, or the target genes. By karyotyping and whole genome sequencing analysis, we confirmed that CRISPR-Cas9 editing did not introduce chromosomal changes or unintended genome editing sites. All mutated genes in both diploid and tetraploid regenerants were heritable in the next generation. spsgs3 null T0 regenerants and sprdr6 null T1 progeny had wiry, sterile phenotypes in both diploid and tetraploid lines. The sterility of the spsgs3 null mutant was partially rescued, and fruits were obtained by grafting to wild-type (WT) stock and pollination with WT pollen. The resulting seeds contained the mutated alleles. Tomato yellow leaf curl virus proliferated at higher levels in spsgs3 and sprdr6 mutants than in the WT. Therefore, this protoplast regeneration technique should greatly facilitate tomato polyploidization and enable the use of CRISPR-Cas for S. peruvianum domestication and tomato breeding.

The clinical prospect of sonodynamic therapy (SDT) has not been fully realized due to the scarcity of efficient sonosensitizers. Herein, we designed phthalocyanine-artesunate conjugates (e.g. ZnPcT4 A), which could generate up to ca. 10-fold more reactive oxygen species (ROS) than the known sonosensitizer protoporphyrinâ IX. Meanwhile, an interesting and significant finding of aggregation-enhanced sonodynamic activity (AESA) was observed for the first time. ZnPcT4 A showed about 60-fold higher sonodynamic ROS generation in the aggregated form than in the disaggregated form in aqueous solutions. That could be attributed to the boosted ultrasonic cavitation of nanostructures. The level of the AESA effect depended on the aggregation ability of sonosensitizer molecules and the particle size of their aggregates. Moreover, biological studies demonstrated that ZnPcT4 A had high anticancer activities and biosafety. This study thus opens up a new avenue the development of efficient organic sonosensitizers.

Objective: The Advance Care Planning Engagement Survey (ACP-ES) has proven effective in evaluating individuals' engagement in advance care planning (ACP). However, a Traditional Chinese version of ACP-ES (ACPES-TC) has not yet been developed. Therefore, this study aimed to translate and preliminarily validate the ACPES-TC in the Taiwanese context. Material and Methods: A forward and backward translation process was conducted. The translated questionnaire was confirmed by clinical and academic experts. The ACPES-TC was then evaluated for its reliability and validity with participants in the community and from an outpatient clinic in a medical center in Northern Taiwan. The participants comprised healthy people aged 20 to 30 years and patients ≥55 years old, recruited from September 17 to October 28, 2019. Results: Seventy people were recruited, including 20 people aged 20 to 30 years in the community and 50 patients ≥ 55 years old from clinics. The ACPES-TC scores are significantly higher among those of older age, having financial independence, and under long-term medication (p < .05). The patients' preference for health-related decision-making is significantly correlated with the ACPES-TC score; the point-biserial correlation coefficient is 0.46 (p < .001). The discriminant and criterion-related validities are verified. The ACPES-TC demonstrated a good internal consistency (Cronbach's α .97), acceptable one-week test-retest reliability (overall intraclass correlation coefficient 0.86), and low practice effect between the test and retest (Cohen's d .43). Conclusion: The overall reliability and validity of the ACPES-TC are fair, which could be used to evaluate the patients' engagement in ACP in Taiwan. However, further studies with a full-scale psychometric evaluation are needed.

RESUMEN
Sonneratia apetala Buch-Ham., an exotic mangrove species with antidiabetic, antibacterial, and antioxidant capacities, mainly distributes in the southeast coastal areas in China. The present work investigated the protective effects of Sonneratia apetala leaves and branches extraction (SAL) on hyperuricemia (HUA) in mice. Potassium oxonate (PO) and hypoxanthine (HX) were used to establish the HUA model by challenge for consecutive 7 days. Results revealed that SAL inhibited the increases in kidney weight and index compared to the vehicle group. Meanwhile, SAL significantly decreased the levels of uric acid (UA), creatinine (CRE), and blood urea nitrogen (BUN) in serum. Additionally, SAL inhibited the activity of xanthine oxidase (XOD) in the liver. SAL ameliorated PO- and HX-induced histopathological changes. Moreover, it regulated oxidative stress markers including malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD) activity, and glutathione (GSH) content. Also, SAL inhibited the increases in renal levels of interleukin-6 (IL-6), interleukin-18 (IL-18), interleukin-1ß (IL-1ß), tumor necrosis factor (TNF-α), monocyte chemotactic protein 1 (MCP-1), and transforming growth factor-ß (TGF-ß). SAL remarkably reduced suppressor of cytokine signaling 3 (SOCS3), Janus kinase 2 (JAK2), and subsequent phosphorylation of signal transducer and activator of transcription 3 (STAT3) expression. In addition, SAL inhibited the activation of nuclear factor kappa-B (NF-κB) in the kidney. Furthermore, SAL protected against HUA by regulating renal UA transporters of organic anion transporter (OAT1), urate reabsorption transporter 1 (URAT1), and glucose transporter 9 (GLUT9). These findings suggested that SAL ameliorated HUA by inhibiting the production of uric acid and enhancing renal urate excretion, which are related to oxidative stress and inflammation, and the possible molecular mechanisms include its ability to inhibit the JAK/STAT signaling pathway. Thus, SAL might be developed into a promising agent for HUA treatments.
