Flap transplantation is widely used in reconstructive surgery; however, ischemic injury remains a critical barrier to flap survival, primarily due to oxidative stress, ferroptosis, and impaired angiogenesis. In this study, we employed a random-pattern skin flap model in Sprague–Dawley rats to evaluate the protective effects of curcumin (Cur). Cur administration significantly enhanced antioxidant capacity by increasing superoxide dismutase (SOD) activity and heme oxygenase-1 (HO-1) expression while decreasing malondialdehyde (MDA) and lipid peroxidation (LPO) levels. Ferroptosis analysis revealed that Cur upregulated SLC7A11, GPX4, and FTH1 while downregulating ACSL4, indicating ferroptosis inhibition. Mechanistically, Cur activated the FoXO1/NCOA4 signaling pathway, suppressing NCOA4-mediated ferritinophagy and limiting iron-driven oxidative damage. Moreover, Cur promoted angiogenesis by upregulating VEGF, MMP9, and CDH5 and enhanced human umbilical vein endothelial cell (HUVEC) proliferation while reducing intracellular reactive oxygen species (ROS). Collectively, these findings demonstrate that Cur mitigates ischemic injury through antioxidative, antiferroptotic, and proangiogenic effects, supporting its therapeutic potential for improving flap survival in reconstructive surgery.

皮瓣移植在重建外科中应用广泛;然而,缺血性损伤仍然是皮瓣存活的关键障碍,主要是由于氧化应激、铁下垂和血管生成受损。本研究采用Sprague-Dawley大鼠随机皮瓣模型来评价姜黄素(Cur)的保护作用。通过增加超氧化物歧化酶(SOD)活性和血红素加氧酶-1 (HO-1)表达,降低丙二醛(MDA)和脂质过氧化(LPO)水平,显著提高了抗氧化能力。铁下垂分析显示,Cur上调SLC7A11、GPX4和FTH1,下调ACSL4,表明铁下垂有抑制作用。在机制上,Cur激活了FoXO1/NCOA4信号通路,抑制了NCOA4介导的铁蛋白自噬,限制了铁驱动的氧化损伤。此外,Cur通过上调VEGF、MMP9和CDH5促进血管生成,增强人脐静脉内皮细胞(HUVEC)的增殖,同时减少细胞内活性氧(ROS)。总的来说,这些发现表明,Cur通过抗氧化、抗铁沉降和促血管生成的作用减轻了缺血性损伤,支持其在重建手术中提高皮瓣存活率的治疗潜力。

Background

The primary headache disorder, cluster headache (CH), is known as one of the most painful conditions a human can experience. This study aimed to explore the psychological experience of living with CH, both during acute headache attacks and between attacks.

Methods

Semistructured interviews were conducted with 13 adults with episodic or chronic CH. Interviews were carried out via Microsoft Teams or the telephone. Qualitative interview data were analysed using Reflective Thematic Analysis (RTA) through a critical realist lens. Participants also completed the Pain Self-Efficacy Questionnaire and Pain Catastrophising Scale.

Results

RTA resulted in five themes emerging related to the psychological experience of CH: “Darkness,” “Battling,” “Shifting,” “Control,” and “Despair.” Psychological experiences during the acute attack appeared distinct from experiences of the condition between attacks. The psychological experience was impacted by how long participants had lived with the condition and by whether they had the episodic or chronic form. Individuals living with the chronic form of CH reported increased despair and depression, due to lack of respite from the pain. In contrast, individuals living with episodic CH were less despairing due to pain-free periods but talked to increased uncertainty, with it being unclear when the painful bout would disrupt their life.

Conclusion

Living with CH is a complex and challenging psychological experience. Further research to identify how psychological processes may maintain distress and exacerbate pain could help establish a psychological model of CH. Such a model could, in turn, enable exploration of psychological techniques to support individuals during and between CH attacks. Authors also call for research to explore how to increase visibility of CH.

原发性头痛疾病丛集性头痛(CH)被认为是人类可能经历的最痛苦的疾病之一。本研究旨在探讨慢性头痛患者在急性头痛发作期间和发作之间的心理体验。方法 半结构式访谈进行了13个成年人情景或慢性CH。面试通过微软团队或电话进行。通过批判性现实主义视角,运用反思性主题分析(RTA)对定性访谈数据进行分析。参与者还完成了疼痛自我效能感问卷和疼痛灾变量表。RTA产生了与CH的心理体验相关的五个主题:“黑暗”、“战斗”、“转移”、“控制”和“绝望”。急性发作期间的心理体验与发作间状态的体验明显不同。参与者的心理体验受其患病时间长短以及他们是发作型还是慢性型的影响。个人生活在慢性的CH报道形式增加绝望和抑郁,由于缺乏从痛苦喘息的机会。相比之下,患有发作性CH的人由于无疼痛期而不那么绝望,但他们的不确定性增加了,不清楚痛苦的发作何时会扰乱他们的生活。结论与CH一起生活是一种复杂而富有挑战性的心理体验。进一步研究心理过程是如何维持痛苦和加剧疼痛的,可以帮助建立CH的心理模型。这样的模型反过来可以探索心理技术,在CH发作期间和发作之间为个体提供支持。作者还呼吁研究如何提高CH的知名度。

Background

To analyze the subsequent conversion situation and associated risk factors in patients with mild subclinical hypothyroidism.

Methods

A retrospective review was conducted using thyroid function data from health examinations at Zhongshan Hospital, Fudan University, from 2012 to 2022. A total of 12,394 patients with initial subclinical hypothyroidism (SCH) were included. Subsequent thyroid function results were categorized into four outcomes: progression to overt hypothyroidism (115), progression to severe-SCH (191), maintenance of mild-SCH (5658), and reversion to euthyroidism (6430). The correlation between baseline parameters and thyroid function levels with the conversion outcomes within 2 years was analyzed using multinomial logistic regression analysis.

Results

Lower baseline FT4 was strongly associated with overt hypothyroidism progression (OR = 0.366, p < 0.001), with the lowest FT4 quartile showing an 8-fold higher overt hypothyroidism incidence (3.02%) compared to other quartiles. In contrast, higher baseline TSH was the primary driver of severe-SCH progression (OR = 1.898, p < 0.001), with the highest TSH quartile having a 7-fold higher severe-SCH incidence (4.83%). Baseline TSH inversely correlated with euthyroidism reversion rates, with milder TSH elevations more likely to normalize.

Conclusions

FT4 and TSH exhibit distinct predictive roles in mild-SCH progression: low FT4 drives overt hypothyroidism conversion, while high TSH predicts severe-SCH. Combining both markers may improve risk stratification for tailored follow-up and intervention. Prospective studies with treatment records are needed to validate these findings.

背景分析轻度亚临床甲状腺功能减退患者的后续转化情况及相关危险因素。方法回顾性分析2012 - 2022年复旦大学中山医院甲状腺功能体检资料。本研究共纳入12394例首发亚临床甲状腺功能减退(SCH)患者。随后的甲状腺功能结果分为四种结果:进展到明显的甲状腺功能减退(115),进展到严重的甲状腺功能减退(191),维持轻度甲状腺功能减退(5658),恢复到甲状腺功能减退(6430)。采用多项logistic回归分析基线参数和甲状腺功能水平与2年内转换结果的相关性。结果基线FT4较低与明显甲状腺功能减退进展密切相关(OR = 0.366, p < 0.001), FT4最低的四分位数显示明显甲状腺功能减退发生率比其他四分位数高8倍(3.02%)。相比之下,较高的基线TSH是严重sch进展的主要驱动因素(OR = 1.898, p < 0.001),最高TSH四分位数的严重sch发生率高出7倍(4.83%)。基线TSH与甲亢逆转率呈负相关,轻度TSH升高更有可能恢复正常。结论FT4和TSH在轻度sch进展中具有明显的预测作用:低FT4驱动明显的甲状腺功能减退转化,而高TSH预测严重sch。结合这两种指标可以改善风险分层,以便进行针对性的随访和干预。需要有治疗记录的前瞻性研究来验证这些发现。

Background

Severe pneumonia remains a leading cause of high mortality globally. While numerous new detection markers for pneumonia of this type have been introduced in clinical practice, their application in primary healthcare settings remains limited. The neutrophil-to-lymphocyte-to-monocyte ratio (NLMR) is a simple and easily accessible parameter. The aim of this study was to explore its potential as an early warning indicator for the prognosis of pneumonia.

Methods

We conducted a retrospective analysis of the first pneumonia patients admitted to the intensive care unit (ICU) from January 2019 to June 2025. We compared the 24 h scores and laboratory data of the survival group and with those of the nonsurvival group, analyzed the prognostic factors for pneumonia via multivariate logistic regression, and assessed their predictive value via receiver operating characteristic (ROC) curves. The Kaplan–Meier (K–M) method was used to estimate survival outcomes on the basis of differing ICU admission NLMR levels.

Results

The study included a total of 181 patients, 39 of whom died within 30 days. Compared with the survival group, the nonsurvival group presented significantly higher NLMR values upon ICU admission. The multivariate binary logistic analysis revealed that the NLMR independently contributed to an increased risk of mortality (OR = 1.013, 95% CI 1.00–1.018; p < 0.05). The NLMR exhibited an ROC-AUC of 0.844 (95% CI, 0.768–0.921), and both the Hosmer–Lemeshow test and calibration plots indicated superior accuracy for the NLMR model. K–M analysis demonstrated that higher NLMR values at ICU admission were associated with significantly reduced 30-day survival.

Conclusion

Elevated NLMR at ICU admission was an independent risk factor for increased 30-day mortality in patients with pneumonia, especially when the NLMR was greater than 120.

背景:严重肺炎仍然是全球高死亡率的主要原因。虽然在临床实践中已经引入了许多这种类型的肺炎的新检测标记物,但它们在初级卫生保健机构中的应用仍然有限。中性粒细胞/淋巴细胞/单核细胞比值(NLMR)是一个简单且容易获得的参数。本研究的目的是探讨其作为肺炎预后早期预警指标的潜力。方法对2019年1月至2025年6月我院重症监护病房(ICU)收治的首批肺炎患者进行回顾性分析。我们比较存活组与非存活组的24小时评分和实验室数据,通过多因素logistic回归分析肺炎的预后因素,并通过受试者工作特征(ROC)曲线评估其预测价值。Kaplan-Meier (K-M)法用于根据不同的ICU入院NLMR水平估计生存结果。结果共纳入181例患者,其中39例在30天内死亡。与生存组相比,非生存组入院时NLMR值明显高于生存组。多变量二元logistic分析显示NLMR独立导致死亡风险增加(OR = 1.013, 95% CI 1.00-1.018; p < 0.05)。NLMR模型的ROC-AUC为0.844 (95% CI为0.768 ~ 0.921),Hosmer-Lemeshow检验和校正图均显示NLMR模型具有较高的准确性。K-M分析显示,ICU入院时NLMR值较高与30天生存率显著降低相关。结论入院时NLMR升高是肺炎患者30天死亡率升高的独立危险因素,特别是当NLMR大于120时。

Background

There is growing evidence that platelet-related parameters can influence a wide range of cardiovascular diseases. However, the effect of platelet-related parameters on cardiac hypertrophy is unknown. To verify this, the present study proposes to use Mendelian randomization (MR) to explore bidirectional causality between multiple platelet-related parameters and cardiac hypertrophy and to assess the potential mediating role of plasma metabolites.

Methods

Single-nucleotide polymorphisms (SNPs), the instrumental variable required for the study, were obtained through the public genome-wide association study (GWAS) database, and samples were obtained from European populations. We obtained summary statistics of cardiac hypertrophy (4113 cases, 839,403 controls) after GWAS meta-analysis of two independent datasets. In this study, we mainly used the inverse variance weighted (IVW) method to assess the causal effect; two-step MR analysis was used to assess the mediating effect.

Results

MR analysis showed a positive causal relationship between mean platelet volume (MPV) and the risk of cardiac hypertrophy (odds ratio, 1.72 for cardiac hypertrophy per one-standard-deviation increment in MPV; 95% confidence interval, 1.24 to 2.38; p = 0.001). Multivariate MR showed that the risk role of MPV in promoting cardiac hypertrophy persisted after adjustment for other platelet parameters. Mediation analysis via two-step MR showed that this effect was partially mediated by vanillic acid glycine levels, with a mediation ratio of 20.4% (95% confidence interval, 3.7% to 40.7%).

Conclusions

This study revealed a positive causal relationship between MPV and cardiac hypertrophy risk, partly mediated by plasma vanillic acid glycine levels.

越来越多的证据表明,血小板相关参数可以影响广泛的心血管疾病。然而,血小板相关参数对心肌肥厚的影响尚不清楚。为了验证这一点,本研究建议使用孟德尔随机化(Mendelian randomization, MR)来探索多个血小板相关参数与心脏肥厚之间的双向因果关系,并评估血浆代谢物的潜在介导作用。方法通过公共全基因组关联研究(GWAS)数据库获得研究所需的工具变量单核苷酸多态性(snp),样本来自欧洲人群。在对两个独立数据集进行GWAS meta分析后,我们获得了心脏肥厚的汇总统计数据(4113例,839403例对照)。在本研究中,我们主要采用逆方差加权(IVW)方法来评估因果关系;采用两步磁共振分析评估中介效应。结果MR分析显示,平均血小板体积(MPV)与心肌肥厚风险呈正相关(MPV每增加一个标准差,心肌肥厚的优势比为1.72;95%可信区间为1.24 ~ 2.38;p = 0.001)。多变量磁共振显示,在调整其他血小板参数后,MPV在促进心肌肥厚中的危险作用仍然存在。通过两步MR进行的中介分析表明,香草酸甘氨酸水平部分介导了这种效应,中介率为20.4%(95%置信区间为3.7% ~ 40.7%)。结论:本研究揭示了MPV与心肌肥厚风险之间的正因果关系,部分由血浆香草酸甘氨酸水平介导。

<div> <section> <h3> Introduction</h3> <p>Posttraumatic stress disorder (PTSD) is prevalent among military veterans around the world, with many remaining symptomatic despite standard therapies. We hypothesized that warm water immersion might have a positive therapeutic effect on veteran’s mood, anxiety, and pain.</p> </section> <section> <h3> Methods</h3> <p>This clinical trial used a mixed methods approach: a quantitative single case design with repeated measures followed by a qualitative descriptive semistructured interview of participant perceptions and experiences to examine the effects of warm water immersion on improving mood, anxiety, and pain. Veterans with PTSD symptoms and comorbid depression, anxiety, and pain were immersed to the chest in 33°C water for 45 min. Repeated measures of the Multidimensional Mood State Questionnaire and the visual analog scales for anxiety and pain were taken at dry baseline and at 15 and 45 min of immersion, followed by a semistructured interview.</p> </section> <section> <h3> Results</h3> <p>A mixed regression model (Holm–Bonferroni adjusted <i>p</i> values), controlling for veteran participants’ (<i>N</i> = 13; mean age = 31 years; male = 9, female = 4) PTSD symptoms, depression status, and combat score, revealed significant improvements compared to baseline. At 15 min, scores improved for good mood (<i>B</i> = 3.85, SE = 1.21, <i>t</i> = 3.18, <i>p</i> = 0.016), calmness (<i>B</i> = 8.15, SE = 1.57, <i>t</i> = 5.19, <i>p</i> < 0.001), and anxiety (<i>B</i> = −10.92, SE = 4.53, <i>t</i> = −2.41, <i>p</i> = 0.048). At 45 min, improvements were observed in good mood (<i>B</i> = 6.38, SE = 1.21, <i>t</i> = 5.27, <i>p</i> < 0.001), calmness (<i>B</i> = 11.38, SE = 1.57, <i>t</i> = 7.25, <i>p</i> < 0.001), and anxiety (<i>B</i> = −23.69, SE = 4.53, <i>t</i> = −5.23, <i>p</i> < 0.001). Pain scores also improved significantly at 45 min (<i>B</i> = −17.69, SE = 4.42, <i>t</i> = −4.00, <i>p</i> = 0.003). Veterans described the experience as relaxing, calming, pain-relieving, and promoting mental rest as they actively engaged with the properties of the water.</p> </section> <section> <h3> Conclusion</h3> <p>Warm water immersion provides an effective, fast-acting, low-risk, nonstigmatizing, accessible adjunct therapy for veterans experiencing PTSD symptoms and comorbid depression, anxiety, and pain.

创伤后应激障碍(PTSD)在世界各地的退伍军人中普遍存在,尽管有标准的治疗方法,但许多人仍然有症状。我们假设温水浸泡可能对退伍军人的情绪、焦虑和疼痛有积极的治疗作用。方法本临床试验采用混合方法:定量单例设计,重复测量,然后对参与者的感知和经历进行定性描述性半结构化访谈,以检验温水浸泡对改善情绪、焦虑和疼痛的影响。将有PTSD症状并伴有抑郁、焦虑和疼痛的退伍军人浸泡在33°C的水中45分钟。多维情绪状态问卷和焦虑和疼痛的视觉模拟量表在干基线和浸泡15和45分钟时进行重复测量,随后进行半结构化访谈。结果采用混合回归模型(Holm-Bonferroni调整p值),控制了退伍军人(N = 13,平均年龄= 31岁,男= 9,女= 4)PTSD症状、抑郁状态和战斗得分,与基线相比有显著改善。好心情在15分钟,分数提高(B = 3.85, = 1.21, t = 3.18, p = 0.016),冷静(B = 8.15, = 1.57, t = 5.19, p & lt; 0.001),和焦虑(B =−10.92,SE = 4.53, t =−2.41,p = 0.048)。在45分钟,观察改进好心情(B = 6.38, = 1.21, t = 5.27, p & lt; 0.001),冷静(B = 11.38, = 1.57, t = 7.25, p & lt; 0.001),和焦虑(B =−23.69,SE = 4.53, t =−5.23,p & lt; 0.001)。疼痛评分在45 min时也有显著改善(B = - 17.69, SE = 4.42, t = - 4.00, p = 0.003)。老兵们将这种体验描述为放松、平静、缓解疼痛,并在他们积极参与水的特性时促进精神休息。结论温水浸泡是一种有效、快速、低风险、无污名化、可及的辅助治疗方法,可用于治疗退伍军人PTSD症状及伴随的抑郁、焦虑和疼痛。同样的参与者对具有定性主题的心理社会工具的反应的比较也产生了类似的结果,为沉浸式的有效性提供了额外的证据。试验注册ClinicalTrials.gov标识符:NCT0530903

Objective

The 2020/2021 National Heart Failure Audit found prescribing rates of beta-blockers, angiotensin-converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARBs) and mineralocorticoid receptor antagonists (MRAs) were below target levels in individuals with heart failure with reduced ejection fraction (HFrEF). In Sheffield Teaching Hospitals (STH), prescribing rates of this triple therapy (TT) were below the national average. The aim of this study was to evaluate the impact of patients’ frailty and comorbidities on TT prescribing rates.

Methods

We analysed the clinical details of individuals with a diagnosis of moderate or severe HFrEF admitted to STH between May 2021 and December 2021. Patients’ electronic notes, investigations and heart failure specialist nurses’ assessments were reviewed.

Results

Electronic records of 310 patients were reviewed. About 45.5% were discharged on appropriate TT, compared to 52% nationally. Prescribing rates were 84.2% for beta-blockers and 61.3% for ACE-i/ARB/ARNIs, compared to national levels of 91% and 84%, respectively. The prescribing rate for MRA was 63.4%, which is higher than the national average (61%). About 92.6% of those not on TT had a documented clinical reason, with the commonest being ‘poor renal function’ (45.6%) and ‘low systolic blood pressure’ (25.5%). Those not on TT had a greater mean clinical frailty score (4.4 vs. 3.0, p < 0.001), were older (78.4 vs. 67.1, p < 0.001) and had worse 12-month readmission (p < 0.001) and mortality rates (p < 0.001).

Conclusions

Patients’ frailty and comorbidities play a significant role in HFrEF-prescribing patterns. Identifying and addressing the barriers to optimal HFrEF treatment may improve prescribing rates and patient outcomes.

2020/2021年国家心力衰竭审计发现,β受体阻滞剂、血管紧张素转换酶抑制剂(ACEi)、血管紧张素受体阻滞剂(ARBs)和矿皮质激素受体拮抗剂(MRAs)的处方率低于射血分数降低(HFrEF)心力衰竭患者的目标水平。在谢菲尔德教学医院(STH),这种三联疗法(TT)的开方率低于全国平均水平。本研究的目的是评估患者的虚弱和合并症对TT处方率的影响。方法我们分析了2021年5月至2021年12月期间入住STH的诊断为中度或重度HFrEF的个体的临床细节。回顾了患者的电子记录、调查和心力衰竭专科护士的评估。结果回顾了310例患者的电子病历。约45.5%的患者接受了适当的治疗出院,而全国的这一比例为52%。β受体阻滞剂处方率为84.2%,ACE-i/ARB/ aris处方率为61.3%,而全国水平分别为91%和84%。MRA处方率为63.4%,高于全国平均水平(61%)。约92.6%未接受TT治疗的患者有明确的临床原因,其中最常见的是“肾功能不佳”(45.6%)和“收缩压低”(25.5%)。未接受TT治疗的患者平均临床虚弱评分更高(4.4比3.0,p < 0.001),年龄更大(78.4比67.1,p < 0.001), 12个月再入院率更低(p < 0.001),死亡率更低(p < 0.001)。结论患者的虚弱和合并症是影响hfref处方模式的重要因素。识别和解决最佳HFrEF治疗的障碍可能会提高处方率和患者的预后。
