The present study aimed to evaluate the effect of albumin administration on mortality in patients with severe burns. We retrospectively analyzed data from the Diagnosis Procedure Combination Database, a nationwide inpatient database in Japan. We identified patients in the database aged ≥ 15 years who were admitted with severe burns (burn index ≥15) from April 2014 to March 2021. We included patients who received albumin within 2 days of admission in the albumin group and those who did not in the control group. The outcome was the 28-day mortality. Eligible patients (n = 2492) were categorized into an albumin group (n = 1128) or a control group (n = 1364). One-to-one propensity score matching generated 530 pairs of patients with and without albumin administration. The 28-day mortality did not differ significantly between the two groups (albumin vs. control, 21.7 % vs. 22.8 %; risk difference, −1.1 %; 95 % confidence interval, −6.1 % to +3.9 %). These results suggest that albumin administration within 2 days of admission in patients with severe burns may not be associated with mortality during the acute phase.
本研究旨在评估白蛋白用药对严重烧伤患者死亡率的影响。我们回顾性分析了日本全国住院患者数据库--诊断程序组合数据库中的数据。我们在数据库中识别了 2014 年 4 月至 2021 年 3 月期间因重度烧伤(烧伤指数≥15)入院的年龄≥15 岁的患者。我们将入院 2 天内接受白蛋白治疗的患者纳入白蛋白组,将未接受白蛋白治疗的患者纳入对照组。研究结果为 28 天死亡率。符合条件的患者(n = 2492)被分为白蛋白组(n = 1128)或对照组(n = 1364)。一对一倾向评分匹配产生了 530 对服用白蛋白和未服用白蛋白的患者。两组患者的 28 天死亡率差异不大(白蛋白组与对照组相比,21.7% 对 22.8%;风险差异为-1.1%;95% 置信区间为-6.1% 到 +3.9%)。这些结果表明,严重烧伤患者在入院 2 天内服用白蛋白可能与急性期的死亡率无关。

Dressings play a crucial role in the management of burn wound. In this study, the cotton bandage was modified with the Poly (N-isopropylacrylamide) / graphite oxide/nano silver (PNIPAM/GO-Ag) hydrogel to obtain a novel dressing (PNIPAM/GO-Ag/COT). The healing effect of the PNIPAM/GO-Ag/COT dressing on deep second-degree burn wounds in rats and the changes of related inflammatory factors were explored and analyzed systematically. The deep second-degree burn model was established by the steam scald method in Sprague–Dawley (SD) rats. The granulation tissue, collagen deposition, the expressions of tumor necrosis factor-α (TNF-α), and basic fibroblast growth factor (bFGF) of the wound were evaluated by means of the HE staining, Masson staining, ELISA, and immunohistochemistry methods. The results showed that, compared with the blank group (rats without the dressing treatment), the PNIPAM/GO-Ag/COT dressing reduced the expression of TNF-α by approximately 18 % and promoted the bFGF expression in wound tissue. Compared to the control group (rats with the gauze treatment), the wound healing rate in the PNIPAM/GO-Ag/COT dressing group was 58 % on the 14th day, with an increase of 30 %. These results demonstrated that the PNIPAM/GO-Ag/COT dressing primarily promoted burn wound healing by reducing inflammatory reactions, promoting collagen deposition, and enhancing the expression of bFGF.
敷料在烧伤创面的处理中起着至关重要的作用。本研究用聚(N-异丙基丙烯酰胺)/氧化石墨/纳米银(PNIPAM/GO-Ag)水凝胶对棉绷带进行改性,得到了一种新型敷料(PNIPAM/GO-Ag/COT)。系统地探讨和分析了 PNIPAM/GO-Ag/COT 敷料对大鼠深二度烧伤创面的愈合效果以及相关炎症因子的变化。采用蒸汽烫伤法建立 Sprague-Dawley (SD) 大鼠深二度烧伤模型。通过 HE 染色法、Masson 染色法、ELISA 法和免疫组化法对创面的肉芽组织、胶原沉积、肿瘤坏死因子-α(TNF-α)和碱性成纤维细胞生长因子(bFGF)的表达进行了评价。结果表明,与空白组(未使用敷料的大鼠)相比,PNIPAM/GO-Ag/COT敷料降低了伤口组织中TNF-α的表达约18%,并促进了bFGF的表达。与对照组(使用纱布处理的大鼠)相比,PNIPAM/GO-Ag/COT 敷料组在第 14 天的伤口愈合率为 58%,提高了 30%。这些结果表明,PNIPAM/GO-Ag/COT 敷料主要通过减少炎症反应、促进胶原蛋白沉积和增强 bFGF 的表达来促进烧伤创面的愈合。

Clinically, the condition of skeletal muscle injury is the key to the process of high voltage electrical burn (HVEB) wound repair. The aim of this study was to identify the potential mechanisms and intervention targets of skeletal muscle injury after HVEB. A skeletal muscle injury model in SD rats with HVEB was made. Pathological examination and transcriptome sequencing of injured skeletal muscles were performed, and the expression levels of key proteins and genes in related signaling pathways were verified. Skeletal muscle injury was progressively aggravated within 48 h, then the injury was gradually repaired with scar formation occurring within 1 week. The mechanism of skeletal muscle injury is complex and varied, and ferroptosis is one of the mechanisms. The ferrous iron content in the injured skeletal muscle tissue of model rats increased significantly at 24 h after injury. After 24 h, damage to injured skeletal muscle tissue could be alleviated by increasing iron storage and blocking lysosomal phagocytosis of autophagy. Skeletal muscle injury caused by HVEB is characterized by progressive progression after injury. Ferroptosis is involved in the mechanism of HVEB, and iron metabolism-related proteins may be potential targets for preventing progressive skeletal muscle injury.
在临床上,骨骼肌损伤状况是高压电烧伤(HVEB)创面修复过程的关键。本研究旨在确定高压电烧伤后骨骼肌损伤的潜在机制和干预目标。本研究制作了一个高压电烧伤 SD 大鼠骨骼肌损伤模型。对损伤骨骼肌进行了病理学检查和转录组测序,并验证了相关信号通路中关键蛋白和基因的表达水平。骨骼肌损伤在 48 h 内逐渐加重,然后在 1 周内逐渐修复并形成瘢痕。骨骼肌损伤的机制复杂多样,而铁变态反应是其中的一种机制。损伤后 24 小时,模型大鼠骨骼肌损伤组织中的亚铁含量明显增加。24 小时后,通过增加铁储存和阻断溶酶体吞噬自噬,可减轻损伤骨骼肌组织的损伤。由 HVEB 引起的骨骼肌损伤的特点是损伤后进行性进展。铁代谢参与了 HVEB 的机理,铁代谢相关蛋白可能是预防骨骼肌进行性损伤的潜在靶点。

目的:本研究旨在建立一种在严重烧伤急性期有效对抗氧化应激的实验治疗模型,并分析大面积创面缺损的愈合机制:方法:以5只大鼠(2雌3雄)为供体,从腹股沟脂肪垫获取脂肪源性干细胞(ADSC)。干细胞用绿色荧光蛋白标记。研究包括四组,每组17只大鼠,每只大鼠体表30%的面积被3级烫伤;对照组10只大鼠,雌雄数量相等。早期切除后,106个ADSC衍生干细胞被注射到烧伤创面的皮下,并自体移植到干细胞组(n = 17)。早期切除组(n = 17)接受早期切除和自体移植,并在烧伤创缘皮下注射2毫升生理盐水。聚乳酸膜组(n = 17)在烧伤后使用聚乳酸膜敷料。烧伤组(n = 17)不做任何处理。烧伤后第 4 天,各组中的 10 只大鼠被处死,以进行氧化应激评估。对照组(n = 10)在第 4 天牺牲。牺牲后收集血液和组织样本。烧伤后第 4 天,对血液中的氧化应激和炎症以及皮肤、肝脏、肾脏和肺部的细胞损伤进行组织病理学和生物化学研究。烧伤后第 70 天,对伤口愈合进行宏观和组织病理学检查:结果:第4天,氧化应激结果显示,干细胞组(7.4 [6-8.8])、对照组(6.7 [5.9-7.6])和早期切除组(7.5 [6.6-8.5])血液中的总氧化能力(TOC)水平最低,三组之间无显著差异。烧伤组(14.7 [12.5-16.9])的总有机碳含量最高。PLM 组(9.7 [8.6-10.7])的 TOC 含量低于烧伤组,但高于其他组。第 4 天的组织病理学检查显示,在烧伤组中,干细胞组和早期切除组的肝脏 Caspase-3 免疫反应度较低。Caspase-3免疫反应水平如下:干细胞组(20 [10-30])、早期切除组(25 [15-50])、PLM组(70 [50-100])、对照组(0)和烧伤组(80 [60-120])。其他氧化应激和内脏损伤结果与上述结果一致。干细胞组所有大鼠的烧伤伤口都在第70天完全愈合。用免疫荧光显微镜检查干细胞组大鼠的皮肤及其附属器官,发现其呈绿色,表明干细胞的加入:结论:干细胞可能具有形成新皮肤及其附属物的潜力,为大面积皮肤缺损提供更好的愈合效果。大面积深度烧伤后,通过早期切除治疗,去除局部坏死组织,可防止因全身氧化应激和炎症引起的内脏损伤。我们还相信,当这两种治疗方法同时使用时,可以达到最佳效果。

Background

Early retrospective data identify that dysphagia is common in older persons with burn injury, suggesting a rate of 47 %, and that it is associated with medical, burn, and nutritional outcomes.

Aims

To prospectively (1) explore the incidence, (2) describe associations, and (3) evaluate risk factors for dysphagia in patients ≥ 75 years old hospitalised with burn injury.

Methods

All patients > 75 years old admitted to Concord-Repatriation-General-Hospital with burn injury over 4 years (2019–2023) were assessed for dysphagia on presentation and were continually monitored throughout their admission. Burn injury, demographic, and nutritional data were prospectively captured and analysed for association with dysphagia.

Results

Sixty-two patients (33 male) aged 75–95 years (median=83 years) were recruited. Dysphagia was identified in 50 %. Dysphagia was associated with burn size (p = 0.002), pre-existing cognitive impairment (p = 0.000), hospital length of stay (p = 0.001), in-hospital complications (p = 0.000), feeding dependence (p = 0.002), nutritional status (p = 0.013) and enteral feeding duration (p = 0.030). Cognitive impairment was the most sensitive predictor for dysphagia at 100 % (specificity=29 %, NPV=100 %, PPV=59 %). Development of secondary comorbidities was less sensitive at 52 % (NPV 65 %), but was associated with high specificity (90 %) and PPV (84 %).

Conclusions

One in every two patients ≥ 75 years admitted with burn injury will demonstrate dysphagia during their hospital admission. Those with pre-existing cognitive impairment are most at risk.
背景:早期回顾性数据显示,吞咽困难在烧伤老年人中很常见,比例高达 47%,并且与医疗、烧伤和营养结果相关。目的:前瞻性地(1)探讨烧伤住院患者(≥ 75 岁)的发病率,(2)描述相关性,(3)评估吞咽困难的风险因素:在4年(2019-2023年)内,协和-遣返总医院收治的所有年龄大于75岁的烧伤患者在入院时均接受了吞咽困难评估,并在整个入院期间接受持续监测。前瞻性地采集了烧伤、人口统计学和营养学数据,并分析了这些数据与吞咽困难的关系:共招募了 62 名患者(33 名男性),年龄在 75-95 岁之间(中位数=83 岁)。50%的患者被确认为吞咽困难。吞咽困难与烧伤面积(p = 0.002)、原有认知障碍(p = 0.000)、住院时间(p = 0.001)、院内并发症(p = 0.000)、喂养依赖(p = 0.002)、营养状况(p = 0.013)和肠道喂养持续时间(p = 0.030)有关。认知障碍是最敏感的吞咽困难预测指标,其敏感度为 100%(特异性=29%,NPV=100%,PPV=59%)。继发性合并症的敏感性较低,仅为 52%(NPV 65%),但特异性(90%)和 PPV(84%)都很高:结论:每两名年龄≥75 岁的烧伤患者中就有一人会在入院期间出现吞咽困难。已有认知障碍的患者风险最大。

Background

Sepsis is one of the major causes of morbidity and mortality in burn patients. However, the optimal timing of admission which can minimize the probability of sepsis is still unclear. This study aims to determine the optimal time period of admission for severely burned patients and find out the possible reasons for it.

Method

185 victims to the Kunshan factory aluminum dust explosion accident, which happened on August 2nd, 2014, were studied. The optimal cutpoint for continuous variables in survival models was determined by means of the maximally selected rank statistic. Univariate and multivariate analyses were further conducted to verify that admission time was not a risk factor for sepsis. Subgroup analyses were performed to find out possible contributing factors for the result.

Result

The cutoff point for admission time was determined as seven hours, which was supported by the survival curve (p < 0.001). Multivariate analysis showed that, in our study population, delayed admission time was not a risk factor for sepsis (HR = 0.610, 95 %CI = 0.415 - 0.896, p = 0.012). Subgroup analyses showed that “Tracheotomy before admission” (p = 0.002), “Whole blood transfusion” (p < 0.001), “Hemodynamic instability before admission” (p = 0.02), “Has a burn department in the hospital” (p = 0.009), “Has a burn ICU in the hospital” (p < 0.001), “Acute heart failure (AHF)” (p = 0.05), “acute respiratory distress syndrome (ARDS)” (p = 0.05) and “GI bleeding” (p = 0.04) were all statistically significant.

Conclusion

In our study population, we found that delayed admission time was not a risk factor associated with a reduced incidence of sepsis among severely burned patients. This might be attributed to variations in prehospital treatments (whole blood transfusion and tracheotomy), whether the hospital had a burn department/ICU, and certain complications (AHF, ARDS and GI bleeding). It can be inferred that early prehospital care plays a crucial role in reducing sepsis risk among severe burn patients.
败血症是烧伤患者发病和死亡的主要原因之一。然而,能够最大限度降低败血症发生概率的最佳入院时间仍不明确。本研究旨在确定严重烧伤患者的最佳入院时间段,并找出可能的原因。研究收集了2014年8月2日昆山工厂铝粉尘爆炸事故的185名受害者。生存模型中连续变量的最佳切点是通过最大选择秩统计量确定的。进一步进行了单变量和多变量分析,以验证入院时间不是败血症的风险因素。为了找出导致这一结果的可能因素,还进行了分组分析。入院时间的临界点被确定为 7 小时,这得到了生存曲线的支持(P < 0.001)。多变量分析表明,在我们的研究人群中,入院时间延迟并不是脓毒症的风险因素(HR = 0.610, 95 %CI = 0.415 - 0.896, = 0.012)。亚组分析显示,"入院前气管切开术"( = 0.002)、"全血输注"( < 0.001)、"入院前血流动力学不稳定"( = 0.02)、"医院设有烧伤科"( = 0.009)、"医院设有烧伤重症监护室"(< 0.001)、"急性心力衰竭(AHF)"(= 0.05)、"急性呼吸窘迫综合征(ARDS)"(= 0.05)和 "消化道出血"(= 0.04)均有统计学意义。在我们的研究人群中,我们发现入院时间延迟并不是降低严重烧伤患者败血症发病率的风险因素。这可能与院前治疗(全血回输和气管切开术)、医院是否设有烧伤科/重症监护室以及某些并发症(AHF、ARDS 和消化道出血)有关。由此可以推断,早期院前护理在降低严重烧伤患者的败血症风险方面起着至关重要的作用。

Objective

Pain and anxiety are common complications in burn patients, significantly impacting treatment effectiveness and overall patient well-being. Peer counseling, a form of patient education provided by individuals with shared experiences, may hold potential to alleviate this pain and anxiety. This study seeks to investigate the effectiveness of patient-centered education through peer counseling on background pain and state anxiety levels in these patients.

Methods

A two-arm, parallel, randomized, controlled trial design was employed. A total of 86 participants were randomly allocated to one of two groups: control and intervention groups. State anxiety and background pain levels were assessed using the Spielberger State Anxiety Inventory (STAI) and Visual Analogue Scale (VAS), respectively, before and after intervention. Statistical analyses, including Chi-square test, Fisher's exact test, independent t-test, and paired t-test, were employed to analyze the data.

Results

The intervention significantly reduced pain and anxiety in the intervention group compared to baseline (p < .001). There was no significant difference between the control and intervention groups in baseline levels, but there was a significant difference after the intervention (p < .001).

Conclusion

This study demonstrates the efficacy of patient-centered education through peer counseling in reducing background pain and state anxiety levels in burn patients. Compared to standard education, peer counseling led to a more pronounced reduction in both pain and anxiety, suggesting its potential as a valuable nonpharmaceutical intervention to improve patient well-being during burn recovery.

Practice implications

Based on our findings, we recommend that healthcare providers consider implementing peer-based education programs in burn care settings.

Chronic wounds can develop as a result of prolonged inflammation during the healing process, which can happen due to bacterial infection. Therefore, preventing infection and controlling inflammation can accelerate wound healing. Antimicrobial peptides have different protective properties in addition to antimicrobial activity. Some of these activities include the stimulation of cytokine or chemokine synthesis, the facilitation of chemotaxis and cell proliferation, the acceleration of cell proliferation, the induction of anti-inflammatory responses, and the promotion of wound repair. This study aimed to assess the wound healing potential of a novel in silico-designed antimicrobial peptide. Then, its anti-inflammatory activity was investigated by measuring the level of tumor necrosis factor-α (TNF-α) and transforming growth factor beta (TGF-β) as indicators of the wound healing process. In addition, the influence of the peptide on cell migration was evaluated by a scratch test on human dermal fibroblasts (HDF) and HaCaT cells as a human epidermal keratinocyte cell line. The results showed that our new peptide could act well in inhibiting TNF-α over-secretion while increasing the expression of TGF-β as an anti-inflammatory factor. This peptide showed a significant potential to stimulate HDF and HaCaT cell migration and proliferation. Therefore, using this peptide as an anti-inflammatory component of wound dressings may be promising.
在伤口愈合过程中,细菌感染可能导致伤口长期发炎,从而形成慢性伤口。因此,预防感染和控制炎症可以加速伤口愈合。抗菌肽除了具有抗菌活性外,还具有不同的保护特性。其中一些活性包括刺激细胞因子或趋化因子的合成、促进趋化和细胞增殖、加速细胞增殖、诱导抗炎反应以及促进伤口修复。本研究旨在评估一种新型硅设计抗菌肽的伤口愈合潜力。首先,通过测量肿瘤坏死因子-α(TNF-α)和转化生长因子β(TGF-β)的水平来评估该抗菌肽的伤口愈合潜力;然后,通过测量作为伤口愈合过程指标的肿瘤坏死因子-α(TNF-α)和转化生长因子β(TGF-β)的水平来研究该抗菌肽的抗炎活性。此外,还通过对人真皮成纤维细胞(HDF)和人表皮角质细胞系 HaCaT 细胞进行划痕试验,评估了多肽对细胞迁移的影响。结果表明,我们的新肽能很好地抑制 TNF-α 的过度分泌,同时增加作为抗炎因子的 TGF-β 的表达。该肽具有刺激 HDF 和 HaCaT 细胞迁移和增殖的显著潜力。因此,使用这种肽作为伤口敷料的抗炎成分可能很有前景。

Background

The ”one-day-per-percent” rule states that for burn patients, one day of hospital stay can be expected for each percentage of burned body surface. This study aimed to test the rule's predictive value.

Methods

The study is a register-based observational study on all burns treated in the Norwegian National Burn Center 2000–22. All children and adults admitted and actively treated in this period were included (2269 patients). Patients receiving palliative care were not included (55). Age when injured, sex, year of admittance, LOS (length of stay), %TBSA (total body surface area), discharged alive/dead, and palliative care: yes/no were extracted from the registry. Quantile regression was used to estimate the quantiles of LOS/%TBSA as a function of %TBSA.

Results

For injuries < 15 %TBSA, the median LOS/%TBSA values were above 1.0, and the ratio increased as the injury size decreased. The median LOS/%TBSA values were close to 1.0 for patients with injuries ≥ 15 %TBSA (Table 2, Figure 2). The quantile regression analysis revealed a considerable spread in estimated values for both adults and children. Children had a lower median LOS/%TBSA than adults and a value below 1.0 for injuries 15–30 %TBSA. When survivors and non-survivors were compared, a higher median LOS/%TBSA was found for survivors with injuries > 60 %TBSA.

Discussion

The ”one-day-per-percent” rule does not seem applicable for injuries < 15 %TBSA. Even for more extensive injuries, the large spread in estimated values in different quantiles renders it poor at predicting length of hospital stay. There also seem to be many caveats when it is used to measure an institution's efficacy or when comparing different institutions.

Conclusion

The predictive value of the “one-day-per-percent” rule is deficient when considering individual patients. It does not fit for injuries < 15 %TBSA, and the significant variation for patients with injuries of a similar extent renders it not viable as a forecasting tool.

Introduction

Outcome monitoring can identify fluctuations in healthcare. Cumulative sum (CUSUM) analysis can detect when mortality deviates from expected, allowing early intervention through targeted audit. We present a 10-year experience of the prospective use of CUSUM methodology in a regional burn centre.

Method

Prospective outcome monitoring was conducted for all admissions to the intensive care unit between 2012 and 2022. The revised Baux score was used for mortality risk prediction. Risk-adjusted CUSUM charts tracked mortality against that predicted by the revised Baux score. Deviations from expected outcomes triggered detailed structured analysis. Learning outcomes were identified from internal and external governance groups.

Results

CUSUM analysis was triggered on eight occasions: one paediatric (excess deaths), six adult (four excess survivors, two excess deaths) and one elderly (excess survivors). Detailed analysis identified areas for continuous improvement and positive themes from excess survivors.

Conclusion

The use of CUSUM as an early warning trigger stimulates assessment of practice and critical appraisal of factors contributing to unexpected mortality or survival. The revised Baux score at its foundation needs to be carefully considered but remains a valid model. One benefit is positive reinforcement of team cohesion and morale during periods of care excellence leading to excess survivors.
介绍:结果监测可以发现医疗保健中的波动。累积总和(CUSUM)分析可以检测死亡率是否偏离预期,从而通过有针对性的审计进行早期干预。我们介绍了一家地区烧伤中心使用 CUSUM 方法进行前瞻性监测的 10 年经验:方法:我们对 2012 年至 2022 年期间重症监护室的所有入院患者进行了前瞻性结果监测。修订后的Baux评分用于预测死亡风险。风险调整后的 CUSUM 图表根据修订后的 Baux 评分预测结果跟踪死亡率。与预期结果的偏差引发了详细的结构化分析。内部和外部治理小组确定了学习成果:八次触发 CUSUM 分析:一次儿科(超额死亡)、六次成人(四次超额存活、两次超额死亡)和一次老年人(超额存活)。详细分析确定了需要持续改进的领域和超额幸存者的积极主题:结论:使用 CUSUM 作为预警触发器可促进对实践进行评估,并对导致意外死亡或存活的因素进行批判性评价。修订后的 Baux 评分是其基础,需要仔细考虑,但仍然是一个有效的模型。这样做的一个好处是,在卓越护理期间,团队的凝聚力和士气会得到积极加强,从而导致幸存者人数增加。
