An Analysis of the Current Situation and Influence Factors of Narrative Competence Among Nurses in VIP Ward.

Objective: This study aimed to explore the proficiency level in medical narrative ability among nurses in VIP wards and identify the influencing factors. The objective was to provide valuable insights for enhancing the training and development of medical narrative skills among nurses in VIP wards, with the ultimate goal of promoting narrative nursing in clinical practice. Methods: A survey was conducted of 94 nurses working in VIP wards at a grade-A tertiary hospital in Zhongshan City, using the Narrative Competence Scale. Results: The findings revealed that nurses' overall medical narrative ability in VIP wards was relatively low, with a total score of (135.31±16.50). The primary factors identified as influential were professional titles and familiarity with narrative medicine or narrative nursing, which played significant roles. Specifically, nurses with higher professional titles demonstrated greater proficiency in medical storytelling. Moreover, nurses more familiar with narrative medicine or narrative nursing tended to exhibit higher levels of medical narrative ability. Conclusion: The results of this study highlight the significant opportunity for enhancing the medical narrative ability of nurses in VIP wards. To address this issue, it is recommended that training programs incorporate knowledge and skills related to narrative medicine and narrative nursing into the core competency development of VIP nurses. Additionally, there is a need to introduce narrative nursing practices gradually into clinical care. These measures will empower nurses to enhance their narrative abilities, providing superior nursing services to patients. Ultimately, such efforts will strengthen nurses' sense of professional value and increase the social benefits of nursing care.

Evaluating perioperative stresses in children by noninvasive modalities using salivary cortisol and autonomic reactivity.

PURPOSE: Salivary cortisol (SalC) and low to high pulse ratio (LHR) were used for evaluating perioperative stresses in children. METHODS: Children aged 6 months-16 years having elective general (thoracic/abdominal) or minor (open/minimally invasive: MI) procedures underwent pulse monitoring during AM (08:00-12:00) and PM (17:00-21:00) saliva collections from the day before surgery (S-1) to 3 days after surgery (S + 3). SalC/LHR were correlated with age, sex, caregiver attendance, operative time, and surgical site/approach using mixed model analysis and face/numeric pain rating scales (FRS/NRS). RESULTS: Mean ages (years): minor-open (n = 31) 4.7 ± 2.0, thoracic-open (n = 2) 8.7 ± 4.9, thoracic-MI (n = 6) 9.6 ± 6.1, abdominal-open (n = 14) 4.3 ± 4.1, and abdominal-MI (n = 32) 8.0 ± 5.0. Postoperative SalC increased rapidly and decreased to preoperative levels by S + 3 (p < 0.001). LHR increased slightly without decreasing (p = 0.038). SalC correlated positively with operative time (p = 0.036) and open surgery (p = 0.0057), and negatively with age (p < 0.0001) and caregiver attendance (p < 0.001). SalC correlated positively with FRS (n = 51) at S + 2(PM) (p = 0.023), S + 3(AM) (p < 0.001), S + 3(PM) (p = 0.012) and NRS (n = 34) at S + 1(AM) (p = 0.031), S + 3(AM) (p < 0.044). LHR positively correlated with age (p = 0.0072), female sex (p = 0.0047), and caregiver attendance (p = 0.0026). Postoperative SalC after robotic-assisted MI was significantly lower than after open surgery at S + 2(AM) (p = 0.020). CONCLUSIONS: SalC correlated with pain. Caregiver attendance effectively alleviated stress.

The Impact of 5-Aminolevulinic Acid Supplementation on Redox Balance and Aerobic Capacity.

We examined the impact of 5-aminolevulinic acid (5-ALA) and sodium-ferrous-citrate supplementation on aerobic capacity and redox balance through a placebo-controlled, double-blind trial. Fourteen healthy volunteers were randomly assigned to Pla + ALA (4-week placebo followed by 4-week 5-ALA supplementation) or ALA + Pla (4-week 5-ALA supplement followed by a 4-week placebo) group and administered 5-ALA (25 mg/day) or placebo once daily. The participants underwent submaximal incremental cycling tests at weeks 0, 2, 4, 6, and 8. In the cycling test at week 0, individual load-intensity stages required for blood lactate levels >2 mmol/L (lactate threshold, LT) and 4 mmol/L (onset of blood lactate accumulation, OBLA) were determined. The heart rate (HR), blood lactate (La), and oxidative stress markers (diacron reactive oxygen metabolite, d-ROMs; biological antioxidant potential, BAP) were measured at resting, LT, and OBLA states in each cycling test. Marker values were not significantly different between the groups. HR, La, and d-ROMs at resting, LT, and OBLA states were not significantly different among the conditions. BAP and BAP/d-ROMs ratios were significantly different in the OBLA state at week 4 of the 5-ALA group compared with that of the placebo group (p < 0.05). In conclusion, 5-ALA supplementation might improve redox balance during high-intensity aerobic exercise.

Estimating the tuberculosis incidence using a SARIMAX-NNARX hybrid model by integrating meteorological factors in Qinghai Province, China.

Tuberculosis (TB) is recognized as being a major public health concern owing to its increase in Qinghai, China. In this study, we aimed to estimate the long-term effects of meteorological variables on TB incidence and construct an advanced hybrid model with seasonal autoregressive integrated moving average (SARIMA) and a neural network nonlinear autoregression (SARIMAX-NNARX) by integrating meteorological factors and evaluating the model fitting and prediction effect. During 2005-2017, TB experienced an upward trend with obvious periodic and seasonal characteristics, peaking in spring and winter. The results showed that TB incidence was positively correlated with average relative humidity (ARH) with a 2-month lag (ß = 1.889, p = 0.003), but negatively correlated with average atmospheric pressure (AAP) with a 1-month lag (ß = - 1.633, p = 0.012), average temperature (AT) with a 2-month lag (ß = - 0.093, p = 0.027), and average wind speed (AWS) with a 0-month lag (ß = - 13.221, p = 0.033), respectively. The SARIMA (3,1,0)(1,1,1)12, SARIMAX(3,1,0)(1,1,1)12, and SARIMAX(3,1,0)(1,1,1)12-NNARX(15,3) were considered preferred models based on the evaluation criteria. Of them, the SARIMAX-NNARX technique had smaller error values than the SARIMA and SARIMAX models in both fitting and forecasting aspects. The sensitivity analysis also revealed the robustness of the mixture forecasting model. Therefore, the SARIMAX-NNARX model by integrating meteorological variables can be used as an accurate method for forecasting the epidemic trends which would be great importance for TB prevention and control in the coming periods in Qinghai.

Angiotensin Receptor Blockers vs. Beta-Blocker Therapy for Marfan Syndrome: A Systematic Review and Meta-Analysis.

OBJECTIVE: Several RCTs have been conducted to assess the efficacy and safety of angiotensin receptor blocker (ARB) and beta-blocker (BB) therapy for Marfan syndrome (MFS), but the existing evidence is limited and conflicting. This study aimed to compare the efficacy and safety of different therapies. METHODS: The PubMed, Embase, Web of Science, and Cochrane Library databases were electronically searched up to March 2021 to retrieve randomized controlled trials regarding the efficacy and safety of ARB-related (including ARB-only and ARB+BB treatment) and BB-only treatment for treating patients with MFS. The revised risk-of-bias tool was used for quality assessment. The odds ratio (OR) and standard mean difference (SMD) with 95% confidence interval (CI) were used to estimate the pooled effect size. RESULTS: Fourteen reports of 9 trials involving 1,449 patients were included in the meta-analysis. Regarding aortic root dilation, the ARB-related regimen has efficacy comparable with that of the BB-only regimen in patients with MFS (pooled SMD = -0.16, 95% CI [-0.33; 0.01]; P = 0.06), while in the ARB+BB vs. BB-only subgroup, a significant difference was observed (pooled SMD = -0.26; 95% CI [-0.40; -0.11]; P < 0.01). In addition, there were no significant differences in other aortic dilation-related measures (aortic root Z scores, ascending aorta, pulmonary artery, aortic annulus, sinotubular junction, aortic arch, thoracic aorta, and abdominal aorta diameter change) or cardiovascular events (aortic dissection, aortic surgery, and death) between the 2 regimens. CONCLUSION: Our results showed that the clinical efficacy of ARB-only therapy is not inferior to that of BB-only therapy. Moreover, ARB+BB therapy showed superior therapeutic effects without significant adverse effects.

Risk factors of medical device-related pressure injury in intensive care units.

OBJECTIVES: Intensive care unit (ICU) patients are at high risk of medical device related pressure injury (MDRPI). This study aims to ascertain the MDRPI prevalence in ICU patients and analyse the risk factors of MDRPI. BACKGROUND: The occurrence of MDRPI not only increases hospitalisation time with pain and economic burden, but also causes medical disputes. A better understanding of this condition will increase knowledge and facilitate the ability to recognise and prevent MDRPI for clinical nursing staff. However, there are few multicentre studies of MDRPI prevalence in ICU patients in China. DESIGN: A cross-sectional study design was employed. METHODS: Data from 694 patients in 66 adult ICU at 30 hospitals in China were included between October 2018 and March 2019. The stage of each MDRPI was determined according to the definitions of National Pressure Ulcer Advisory Panel. The study methods were followed by the STORBE guidelines. RESULTS: The overall prevalence rate of MDRPI was 13.1% (91/694), with 98 anatomic locations in total. The most common stages of MDRPI were stage 1 (54.1%, 53/98), stage 2 (15.3%, 15/98) and mucosal membrane pressure injury (15.3%, 15/98). MDRPI mainly occurred in the finger (32.7%, 32/98), followed by nose (18.4%, 18/98). The prevalence rate of MDRPI caused by CPAP or BiPAP masks (25%) was highest. Lower Braden scores and having skin oedema were risk factors for MDRPI in adult ICU patients. CONCLUSION: The prevalence of MDRPI in this study was still high. Nurses should take these related factors into consideration when taking care of ICU patients, and appropriate prevention measures should be adopted to decrease the prevalence of MDRPI. RELEVANCE TO CLINICAL PRACTICE: The study can help to improve the PI prevention efforts in ICU patients specific to medical device related PI.

Quality of Life and Its Influencing Factors in Chinese Patients with Chronic Wounds.

OBJECTIVE: To explore the factors influencing quality of life in patients with chronic wounds. METHODS: A total of 138 patients with chronic wounds were included and completed the Chinese version of the Cardiff Wound Impact Schedule, the Hospital Anxiety and Depression Scale, and the Medical Coping Modes Questionnaire after researchers assessed their wound severity. RESULTS: The mean scores of physical symptoms and everyday living, social life, and well-being on the Chinese version of the Cardiff Wound Impact Schedule were 55.65 ± 15.82, 52.69 ± 16.46, and 40.75 ± 13.82, respectively. Multiple regression analysis revealed that depression, coping style, and education level were the primary factors, explaining 51.7% of the variance in physical symptoms and everyday living. Depression and coping style explained 49.6% of the variance in social life. Anxiety and primary disease explained 36.2% of the variance in well-being. CONCLUSIONS: The factors influencing quality of life for these Chinese patients with chronic wounds included education level, primary disease, anxiety, depression, and coping style. Speaking with patients about living with a chronic wound and their potential for healing, understanding their fears about significant changes to their life, and encouraging them to accept such changes can be important for patients and their recovery.

Correlates of stigma for patients with cancer: a systematic review and meta-analysis.

OBJECTIVE: The systematic review and meta-analysis was performed to summarize the available evidence and identify the correlates of cancer stigma. METHODS: PubMed, EMBASE, Web of Science, the Cochrane Library, and PsycINFO were electronically searched to identify eligible studies about correlates of stigma for patients with cancer. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of included studies. A meta-analysis was performed using the statistical program R. RESULTS: Thirty-one studies involving a total of 7114 patients were included in the systematic review and meta-analysis. The results of the meta-analysis showed that cancer stigma shared positive associations with male gender, symptoms, depression, anxiety, body image loss, self-blame, social constraint, intrusive thoughts, and ambivalence over emotional expression, and negative associations with income, NK cell subsets, QOL, self-esteem, self-efficacy, cancer screening attendance, doctor's empathy, and medical satisfaction. The results of the descriptive analysis indicated that cancer stigma was positively associated with self-perception of aging, anger, internal attributions, stressful life events, self-perceived burden, and sleep dysfunction, while negatively associated with patient-provider communication and sleep quality. CONCLUSION: Healthcare staff should pay attention to the identified correlates of cancer stigma. The results of our research can inform the design of interventions to reduce stigma and to improve clinical outcomes in people with cancer.

Ascorbate Oxidase Mimetic Activity of Copper(II) Oxide Nanoparticles.

Although oxidase mimetic nanozymes have been widely investigated, specific biological molecules have rarely been explored as substrates, particularly in the case of ascorbate oxidase (AAO) mimetic nanozymes. Herein, we demonstrate for the first time that copper(II) oxide nanoparticles (CuO NPs) catalyze the oxidation of ascorbic acid (AA) by dissolved O2 (as a green oxidant) to form dehydroascorbic acid (DHAA), thus functioning as a new kind of AAO mimic. Under neutral conditions, the Michaelis-Menten constant of CuO NPs (0.1302 mm) is similar to that of AAO (0.0840 mm). Furthermore, the robustness of CuO NPs is greater than that of AAO, thus making them suitable for applications under various conditions. As a demonstration, a fluorescence AA sensor based on the AAO mimetic activity of CuO NPs was developed. To obtain a fluorescent product, o-phenylenediamine (OPDA) was used to react with the DHAA produced by the oxidation of AA catalyzed by CuO NPs. The developed sensor was cost-effective and easy to fabricate and exhibited high selectivity/sensitivity with a wide linear range (1.25×10-6 to 1.125×10-4 m) and a low detection limit (3.2×10-8 m). The results are expected to aid in expanding the applicability of oxidase mimetic nanozymes in a variety of fields such as biology, medicine, and detection science.

Efficacy of telemedicine for urinary incontinence in women: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: The systematic review and meta-analysis were performed to summarize the available evidence and assess the efficacy of telemedicine for urinary incontinence in women. METHODS: PUBMED, EMBASE, Web of Science, The Cochrane Library, CBM, CNKI, WanFang, and VIP databases were electronically searched to identify eligible studies updated to February 2020 to collect RCTs regarding the efficacy of telemedicine for urinary incontinence in women. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of included studies with the Cochrane Handbook for Systematic Reviews of Interventions. A meta-analysis was performed using RevMan 5.3. RESULTS: Seven studies involving a total of 836 patients were included in the systematic review and meta-analysis. The results of the meta-analysis showed that compared with usual care, telemedicine intervention significantly reduced the UI severity (SMD = -0.90, 95% CI, -1.73 - -0.07, P = 0.003) and improved QOL (SMD = 0.71, 95% CI, 0.21-1.20, P = 0.005). The results of the descriptive analysis indicated that telemedicine intervention can also reduce the patients' anxiety and depression, improving patients' self-efficacy and their impression of improvement. CONCLUSION: The systematic review and meta-analysis demonstrate that telemedicine can reduce the UI severity and anxiety and depression, improving QOL, self-efficacy, and impression of improvement for women with urinary incontinence. Due to the limited quality and quantity of the included studies, rigorous studies with adequate sample sizes are required to conclude with more confidence.

Prevalence of verbal and physical workplace violence against nurses in psychiatric hospitals in China.

OBJECTIVE: Workplace violence (WPV) is common in mental health services in China, but its multi-center prevalence measured using standardized rating scales has rarely been reported. This study aimed to explore the prevalence of verbal and physical violence against nurses working in psychiatric hospitals and examine its independent socio-demographic correlates in China. METHODS: This was a cross-sectional study conducted in 11 major psychiatric hospitals in China using a 9-item self-reported workplace violence scale. RESULTS: A total of 1906 psychiatric nurses were recruited to participate in this study. The one-year prevalence of verbal and/or physical workplace violence (WPV) was 84.2% (95% CI: 82.4-85.8). The prevalence rates of verbal abuse, threats and physical violence were 79.3% (95% CI: 77.4-81.1), 70.9% (95% CI: 68.8-73.0) and 57.9% (95% CI: 55.7-60.2), respectively. Multiple logistic regression analysis revealed that working in department of psychiatry (OR = 3.42, P < 0.001), having moderate (OR = 2.05, P = 0.009), severe (OR = 2.04, P = 0.015) or extremely severe (OR = 3.21, P < 0.001) anxiety level of WPV and working in hospitals with a WPV reporting system (OR = 1.88, P < 0.001) were significantly associated with WPV. CONCLUSION: WPV against nurses is a serious occupational and public health concern in Chinese psychiatric hospitals. Appropriate preventive measures should be undertaken to reduce the risk of WPV in healthcare settings.

Risk factors for the recurrence of diabetic foot ulcers among diabetic patients: a meta-analysis.

This study aimed to systematically review and identify the risk factors for the recurrence of diabetic foot ulcers (DFUs) among diabetic patients. PUBMED, EMBASE, Web of Science, Cochrane Library, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), WanFang, and VIP databases were electronically searched to identify eligible studies updated to January 2019 to collect case-control studies or cohort studies on the risk factors for the recurrence of DFUs. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of included studies using the Newcastle-Ottawa Scale. A meta-analysis was performed using RevMan 5.3. Nine retrospective cohort studies were included, in which 1426 patients were enrolled, 542 in the DFU recurrence group and 884 in the non-recurrent DFU group. Risk factors for the recurrence of DFUs included male gender (odds ratio [OR] = 1.38, 95% confidence interval [CI], 1.07-1.78, P < .05), smoking (OR = 1.66, 95% CI, 1.26-2.20, P = .0004), duration of diabetes (WMD = 4.43, 95% CI, 1.96­6.90, P = .0004), duration of past DFUs (OR = 1.02, 95% CI, 1.00-1.03, P = .006), plantar ulcers (OR = 5.31, 95% CI, 4.93-5.72, P <.00001), peripheral artery disease (OR = 1.65, 95% CI, 1.20-2.28, P = .002), and diabetic peripheral neuropathy (OR = 2.15, 95% CI, 1.40-3.30, P = .0005). No significant differences were found in age, body mass index, total cholesterol, diabetic nephropathy, diabetic retinopathy, or hypertension. Health care staff should pay attention to the identified risk factors for the recurrence of DFUs. Because of the limited quality and quantity of the included studies, rigorous studies with adequate sample sizes are needed to verify the conclusion.

The prevalence and specific characteristics of hospitalised pressure ulcer patients: A multicentre cross-sectional study.

OBJECTIVE: To ascertain the pressure ulcer prevalence in secondary and tertiary general hospitals in different areas of Guangdong Province in China and explore the possible risk factors that are related to pressure ulcers. BACKGROUND: Few multicentre studies have been conducted on pressure ulcer prevalence in Chinese hospitals. DESIGN: A cross-sectional study design was used. METHODS: Data from a total of 25,264 patients were included in the analysis at 25 hospitals in China. The investigators were divided into two groups. The investigators in group 1 examined the patients' skin. When a pressure ulcer was found, a pressure ulcer assessment form was completed. The investigators in group 2 provided guidance to the nurses, who assessed all patients and completed another questionnaire. A multivariate logistic regression analysis was used to analyse the relationship between the possible risk factors and pressure ulcer. RESULTS: The overall prevalence rate of pressure ulcers in the 25 hospitals ranged from 0%-3.49%, with a mean of 1.26%. The most common stage of the pressure ulcers was stage II (41.4%); most common anatomical locations were sacrum (39.5%) and the feet (16.4%). Braden score (p < .001), expected length of stay (p < .001), incontinence (p < .001), care group (p = .011), hospital location (p < .001), type of hospitals (p = .004), ages of patients (p < .001) were associations of pressure ulcers from the multivariate logistic regression analysis. CONCLUSIONS: The overall prevalence rate of pressure ulcers in Chinese hospitals was lower than that reported in previous investigations. Specific characteristics of pressure ulcer patients were as follows: low Braden score, longer expected length of stay, double incontinence, an ICU and a medical ward, hospital location in the Pearl River Delta, a university hospital and an older patient. RELEVANCE TO CLINICAL PRACTICE: The survey could make managers know their prevalence level of pressure ulcers and provide priorities for clinical nurses.

Validation of the nonmotor symptoms questionnaire for Parkinson's disease: results from a Chinese pilot study.

We performed a cross-sectional study of 82 Chinese patients with Parkinson's disease (PD) enrolled during an 18-month period. We used a clinical interview to evaluate a Chinese version of the nonmotor symptoms questionnaire (NMSQuest) as an instrument for measuring the nonmotor symptoms (NMS) in Chinese patients with PD. The patients' cognitive deficit, depression/sleep, disease severity and motor status were assessed based on the mini-mental state examination (MMSE), the Hamilton depression scale (HAMD)/Parkinson's disease sleep scale (PDSS), the modified Hoehn and Yahr staging scale (H&Y) and the unified Parkinson's disease rating scale part III (UPDRS III), respectively. Thirty items distributed in nine different domains of the NMSQuest were evaluated, and the association between the NMSQuest and MMSE, H&Y, UPDRS, HAMD and PDSS was identified. Significant correlations were observed between the NMSQuest and disease duration (rs = 0.272, p = 0.013), UPDRS total score (rs = 0.444, p < 0.001), UPDRS II (rs = 0.415, p < 0.001) and UPDRS III (rs = 0.228, p = 0.039). Furthermore, the sleep disorder and mood (depression/anxiety) domain of the NMSQuest were significantly correlated with the PDSS (rs = -0.471, p < 0.001) and HAMD (rs = 0.687, p < 0.001), respectively. Our results indicate that the Chinese version of the NMSQuest, a useful screening tool, can be considered as a comprehensive, practical measure for NMS evaluation in Chinese PD patients. The NMSQuest highlights the prevalence of the wide range of NMS and indicated good responsiveness and interpretability. We strongly recommend routine use of the simplified Chinese version of NMSQuest in this country.

Dressings for Preventing Pressure Ulcers: A Meta-analysis.

The purpose of this analysis is to determine the effectiveness of dressing material in the prevention of pressure ulcers. Results showed that hydrocolloid, foam, and film were more effective than a standard care protocol in patients at risk for pressure ulcers.

Factors influencing adjustment to a colostomy in Chinese patients: a cross-sectional study.

PURPOSE: We evaluated persons living with a colostomy in order to characterize and describe relationships among adjustment, self-care ability, and social support. SUBJECTS AND SETTING: One hundred twenty-nine colostomy patients from 5 hospitals in Guangzhou, capital city of the Guangdong province, were recruited by convenience sampling. INSTRUMENTS: Cross-sectional data were collected from a survey that included demographic and pertinent clinical data related to their ostomy. The survey also incorporated Chinese language versions of the Ostomy Adjustment Scale, Exercise of Self-Care Agency Scale, and Perceived Social Support Scale. These scales were used to measure the levels and degrees of adjustment, self-care ability, and social support of colostomy patients. METHODS: Respondents completed the survey during outpatient clinics visit after creation of a colostomy. RESULTS: Scores from the Ostomy Adjustment Scale revealed that 96.9% of colostomy patients reported low to moderate adjustment (128.6 ± 19.38) to their stoma. Self-care ability and social support of patients were positively correlated with the adjustment level (R = 0.33, R = 0.21). Several factors, including being a housewife, paying medical expense by oneself, inability to manage the ostomy without assistance, and not participating in an ostomy support group, were associated with a lower level of adjustment (P < .05). Worries about odor and antipathy toward the ostomy significantly contributed to lower levels of adjustment to the stoma (P < .01). CONCLUSION: Overall adjustment to a colostomy was moderate. Self-care ability and social support associated with having a colostomy positively influenced adjustment. Adjustment was also influenced by occupation, health insurance provider, and ability to care for the stoma without requiring assistance.

Stigma and self-esteem in facial burn patients: A correlation study.

BACKGROUND: A considerable number of burn patients have greater psychological stress due to the special trauma site. In clinical practice, it is found that medical staff pay more attention to the rehabilitation of physical function, while the mental health status of patients is greatly neglected. In contact with patients, we found that attention should be paid to the levels of stigma and self-esteem. However, there are few studies on stigma and self-esteem in patients with facial burns. Therefore, this study aimed to describe the stigma and self-esteem levels of facial burns, investigate the relationship between these two variables, and explore the influencing factors of stigma in patients with facial burns, in order to provide evidence for follow-up interventions to improve this population. METHODS: From August 2020 to June 2021, we recruited patients with facial burns who met the inclusion criteria in one burn specialist clinic and three burn units of a tertiary A hospital in Guangzhou, China. The survey tools of this study include sociodemographic and disease-related information questionnaires, the Chinese version of the Social Impact Scale, and the self-esteem scale (these scales were validated). SPSS 25.0 software was used for data analysis through t test, analysis of variance, correlation analysis, multiple linear regression method for data statistics. RESULTS: The total stigma score of facial burn patients was (58.01 ± 7.57), which was at a medium level; the self-esteem score was (19.72 ± 2.43), which was at a low level. Correlation analysis showed that there was a positive correlation between the self-esteem score and the total score of stigma (r = 0.286, P < 0.01). The family per capita monthly income, education level, way of medical expenses expenditure, and self-esteem of facial burn patients were the influencing factors of their stigma, and these factors explained 33.7% of the variation in stigma (F=8.659, P＜0.01). CONCLUSIONS: Patients with facial burns have low levels of stigma and self-esteem, which requires our efforts. In particular, there is a positive correlation between stigma and self-esteem, and self-esteem is an independent risk factor affecting stigma. Our findings suggest that interventions aimed at enhancing self-esteem have the potential to positively impact the reduction of stigma in this patient population.

Suppressive effect of Yokukansan on glutamate released from canine keratinocytes.

Background: Canine atopic dermatitis (CAD) is caused by skin barrier dysfunction due to allergen exposure. Excessive glutamate release in the skin is associated with delayed skin barrier function recovery and epidermal thickening and lichenification. Treatment with Yokukansan (YKS), a traditional Japanese medicine, reduces dermatitis severity and scratching behavior in NC/Nga mice by decreasing epidermal glutamate levels. However, the association between canine keratinocytes and glutamate and the mechanism by which YKS inhibits glutamate release from keratinocytes remains unknown. Aim: We aimed to investigate glutamate release from canine progenitor epidermal keratinocytes (CPEKs) and the inhibitory effect of YKS on this release. We also explored the underlying mechanism of YKS to enable its application in CAD treatment. Methods: Glutamate produced from CPEKs in the medium at 24 hours was measured. The measurement conditions varied in terms of cell density and YKS concentration. CPEKs were treated with a glutamate receptor antagonist (MK-801), a glutamate transporter antagonist (THA), and a glutamate dehydrogenase inhibitor (epigallocatechin gallate; EGCG), and the inhibitory effect of YKS, YKS + THA, MK-801, and EGCG on this release was determined. MK-801 and glutamate dehydrogenase inhibitor were tested alone, and THA was tested in combination with YKS. Finally, glutamine incorporated into CPEKs at 24 hours was measured using radioisotope labeling. Results: CPEKs released glutamate in a cell density-dependent manner, inhibited by YKS in a concentration-dependent manner. Moreover, YKS reduced the intracellular uptake of radioisotope-labeled glutamine in a concentration-dependent manner. No involvement of glutamate receptor antagonism or activation of glutamate transporters was found, as suggested by previous studies. In addition, EGCG could inhibit glutamate release from CPEKs. Conclusion: Our findings indicated that glutamate release from CPEKs could be effectively inhibited by YKS, suggesting the utility of YKS in maintaining skin barrier function during CAD. In addition, CPEKs are appropriate for analyzing the mechanism of YKS. However, we found that the mechanism of action of YKS differs from that reported in previous studies, suggesting that it may have had a similar effect to EGCG in this study. Further research is warranted to understand the exact mechanism and clinical efficacy in treating CAD.

Does tomato juice consumption have a positive effect on the physical and psychological states of individuals in the Coronavirus era?

OBJECTIVES: This preliminary study aims to examine the effects of tomato juice, which can be easily consumed regularly, on the physical and psychological states of healthy adults in the Coronavirus era. DESIGN: Prospective observational study. MATERIALS AND METHODS: Ten healthy adults (mean age, 39.7±4.2 years) who consumed 180 mL of tomato juice twice daily for 4 weeks were enrolled. Measurements were taken before and after 4 weeks of consumption for the items below. Five salivary stress biomarkers (cortisol, α-amylase, secretory immunoglobulin A, chromogranin A, and oxytocin) were measured using approximately 1ml of passively pooled saliva samples, which were stored at -20°C until measurement. Autonomic nervous system (ANS) activity was evaluated using an acceleration pulse wave meter. Skin moisture content and transepidermal water loss (TEWL) were measured using Multi Display devices® MDD4 with specific probes. Subjective psychological states were assessed using Profile of Mood Status (POMS2®) and a survey on skin condition was conducted. RESULTS: As for salivary stress biomarkers, tomato juice intake reduced cortisol and significantly increased oxytocin levels (p = 0.0427). No significant changes were observed in ANS activity.
