    背景:本研究旨在阐明希瓦氏菌相关手术部位感染(SSIs)的临床特征,并通过建立预测模型来评估患者的死亡风险。患者和方法:通过电子病历(EMR)系统对过去十年中与Shewanella相关的SSI患者的病史和实验室数据进行了回顾性分析。采用血浆白细胞介素-6(IL-6)水平结合Howell-PIRO评分系统建立了希瓦氏菌相关性SSI患者死亡风险预测模型。结果:在过去的10年里,从胆汁等标本中分离出45株希瓦氏菌,引流液,消化道SSIs患者的全血。其中,45例(46.67%)患者中有21例接受了消化系统恶性肿瘤切除术,45例患者中有14例(31.11%)行内镜逆行胰胆管造影术(ERCP)胆总管探查或取石,45例患者中有7例(15.56%)为创伤修复伴骨折和腹部损伤患者。在45例与希瓦氏菌相关的SSI患者中,10人在感染后30天内死亡,六例涉及感染两种以上的其他细菌。联合使用IL-6和Howell-PIRO评分进行死亡风险评估产生了受试者工作特征(ROC)曲线,曲线下面积(AUC)为0.9350,阳性预测值为92.71%,阴性预测值为94.58%,诊断灵敏度为95.35%,诊断特异性为92.14%-均高于单独使用IL-6或Howell-PIRO评分的模型。结论:我们发现沿海地区的居民面临与Shewanella相关的SSI的风险增加。此外,与Shewanella相关的SSI同时发生的微生物感染数量越高,患者死亡率越高。血浆IL-6水平和Howell-PIRO评分系统的联合应用有利于评估患者死亡风险,指导及时积极的临床干预。
    Background: This study aims to elucidate the clinical characteristics of Shewanella-related surgical site infections (SSIs) and assess the risk of mortality in patients by establishing a predictive model. Patients and Methods: A retrospective analysis of medical history and laboratory data of Shewanella-related SSI patients over the past decade was conducted via the electronic medical record (EMR) system. A predictive model for mortality risk in Shewanella-related SSI patients was established using plasma interleukin-6 (IL-6) levels combined with the Howell-PIRO scoring system. Results: Over the past 10 years, 45 strains of Shewanella were isolated from specimens such as bile, drainage fluid, and whole blood in patients with digestive tract SSIs. Among them, 21 of 45 (46.67%) patients underwent malignant tumor resection of the digestive system, 14 of 45 (31.11%) underwent endoscopic retrograde cholangiopancreatography (ERCP) common bile duct exploration or the stone removal, and seven of 45 (15.56%) were trauma repair patients with fractures and abdominal injuries. Among the 45 Shewanella-related SSI patients, 10 died within 30 days of infection, six cases involved infections with more than two other types of bacteria. The combined use of IL-6 and Howell-PIRO scores for mortality risk assessment yielded an receiver operating characteristic (ROC) curve with an area under the curve (AUC) of 0.9350, a positive predictive value of 92.71%, a negative predictive value of 94.58%, a diagnostic sensitivity of 95.35%, and a diagnostic specificity of 92.14%-all higher than the model using IL-6 or Howell-PIRO scores alone. Conclusions: We found that residents in coastal areas faced an increased risk of Shewanella-related SSI. Moreover, the higher the number of concurrent microbial infections occurring alongside Shewanella-related SSI, the greater the mortality rate among patients. The combined application of plasma IL-6 levels and the Howell-PIRO scoring system is beneficial for assessing patient mortality risk and guiding timely and proactive clinical interventions.

    乳腺癌是全球女性中最常见的诊断癌症。这些患者的主要治疗方法是手术。然而,乳腺癌患者手术部位感染(SSI)发生率较高.这项研究的目的是确定有效的感染相关诊断标志物,以及时诊断和治疗SSI。
    这项回顾性研究包括2018年7月至2023年3月在山东省肿瘤医院和研究所接受治疗的263例乳腺癌患者。我们分析了SSI组和对照组之间的差异以及感染前和感染期间的差异。最后,我们测试了病原微生物的分布及其对抗生素的敏感性。
    与术前炎症指标相比,白细胞(WBC),中性粒细胞(NEU),绝对中性粒细胞计数与绝对淋巴细胞计数(NLR),D2聚合物(D-二聚体)和纤维蛋白原(FIB)显着增加,而淋巴细胞(LYM),SSI组白蛋白(ALB)和前白蛋白(PA)显著降低。与未感染患者相比,WBC,NEU,NLR和FIB显著增加,SSI患者ALB和PA显著降低,而LYM和D-二聚体没有显著差异。SSI患者感染细菌分布显示,金黄色葡萄球菌感染患者比例高达70.41%;其中,耐甲氧西林金黄色葡萄球菌(MRSA)感染占19.33%。WBC的受试者工作曲线(ROC)的曲线下面积(AUC),NEU,NLR,FIB,ALB和PA分别为0.807、0.811、0.730、0.705、0.663和0.796。其他炎症指标的AUC无统计学意义。与革兰氏阳性菌相比,金黄色葡萄球菌的抗生素耐药性没有显着差异。革兰阳性菌对头孢曲松(CRO)的耐药性,头孢西丁(福克斯),氯霉素(CHL),米诺环素(MNO)和四环素(TCY)低于革兰氏阴性菌,而对庆大霉素(GEN)的耐药性较高。
    这项研究表明,白细胞,NEU,NLR,FIB和PA对识别有SSI风险的患者具有良好的预测价值。炎症指标的截断值有助于SSI的预防和诊断。
    Breast cancer is the most commonly diagnostic cancer in women worldwide. The main treatment for these patients is surgery. However, there is a high incidence of surgical site infection (SSI) in breast cancer patients. The aim of this study was to identify effective infection-related diagnostic markers for timely diagnosis and treatment of SSI.
    This retrospective study included 263 breast cancer patients who were treated between July 2018 and March 2023 at the Shandong Cancer Hospital and Institute. We analyzed differences between the SSI group and control group and differences before and during infection in the SSI group. Finally, we tested the distribution of pathogenic microorganisms and their susceptibility to antibiotics.
    Compared with preoperative inflammatory indicators, white blood cells (WBC), neutrophils (NEU), absolute neutrophil count to the absolute lymphocyte count (NLR), D2 polymers (D-Dimer) and fibrinogen (FIB) were significantly increased, while lymphocytes (LYM), albumin (ALB) and prealbumin (PA) were significantly decreased in the SSI group. Compared with uninfected patients, WBC, NEU, NLR and FIB were significantly increased, ALB and PA were significantly decreased in SSI patients, while LYM and D-Dimer did not differ significantly. The distribution of infection bacteria in SSI patients showed that the proportion of patients with Staphylococcus aureus infection was as high as 70.41%; of those patients, 19.33% had methicillin-resistant Staphylococcus aureus (MRSA) infection. The area under the curves (AUCs) of the receiver operating curves (ROCs) for WBC, NEU, NLR, FIB, ALB and PA were 0.807, 0.811, 0.730, 0.705, 0.663 and 0.796, respectively. The AUCs for other inflammatory indicators were not statistically significant. There was no significant difference in antibiotic resistance for Staphylococcus aureus when compared to that of gram-positive bacteria. The resistance of gram-positive bacteria to ceftriaxone (CRO), cefoxitin (FOX), chloramphenicol (CHL), minocycline (MNO) and tetracycline (TCY) was lower than that of gram-negative bacteria, while the resistance to gentamicin (GEN) was higher.
    This study demonstrated that WBC, NEU, NLR, FIB and PA have good predictive value for identifying patients at risk of SSI. The cut-off values of inflammatory indicators can be helpful in the prevention and diagnosis of SSI.

  • 文章类型: Meta-Analysis
    背景:手术部位感染(SSI)是肠道手术的严重并发症。在这个荟萃分析中,我们旨在探讨术前不同口服抗生素制剂(OABP)与静脉抗生素制剂(IVAP)和/或机械肠道准备(MBP)的疗效和安全性.
    方法:进行了一项荟萃分析,包括成年患者在择期肠道手术的术前准备期间使用口服抗生素与其他方案。结果包括整体SSI,器官空间SSI,浅层SSI,深SSI,和死亡率。
    结果:共有35项随机对照试验(RCTs),由8,445名成年患者组成,纳入我们目前的分析。在29个RCTs中,OABP方案联合IVAP。总的来说,OABP组的整体SSI发生率低于单独IVAP组或IVAP+MBP组(RR0.56,95%CI0.46-0.69,P<0.00001,I2=47%).甲硝唑加喹诺酮类或氨基糖苷类在降低整体SSI方面表现出最佳效果。OABP联合术前和术后IVAP均与降低SSI显著相关。IVAP术前及术后24h内显示出最好的优势。无IVAP的OABP组与对照组在降低SSI方面无差异。OABP方案还显示器官空间SSI的发生率较低,浅层SSI,深SSI,和死亡率。
    结论:OABP联合术前IVAP和术后24h内可显著降低肠道手术中SSI的发生率。甲硝唑与喹诺酮类或氨基糖苷类可能是OABP方案的合适组合。
    Surgical site infection (SSI) is a serious complication of intestinal surgery. In this meta-analysis, we aimed to explore the efficacy and safety of different preoperative oral antibiotic preparation (OABP) compared with intravenous antibiotic preparation (IVAP) and/or mechanical bowel preparation (MBP).
    A meta-analysis consisting of adult patients adopting oral antibiotics versus other regimens during the preoperative preparation of elective intestinal surgery was performed. The outcome included overall SSI, organ space SSI, superficial SSI, deep SSI, and mortality rate.
    A total of 35 randomized controlled trials (RCTs) consisting of 8445 adult patients were included in our present analysis. OABP regimens were combined with IVAP in 29 RCTs. In general, the incidence of overall SSI in the OABP group was less compared with the IVAP alone or IVAP+MBP group (RR 0.56, 95% CI 0.46-0.69, P < .00001, I2 = 47%). Metronidazoles plus quinolones or aminoglycosides showed the best effect on reducing the overall SSI. OABP in combination with preoperative and postoperative IVAP was both significantly associated with reduced SSI. IVAP before and within 24 h after surgery showed the best advantage. No difference was found between the OABP without IVAP group and the control group in reducing SSI. OABP regimens also demonstrated a lower incidence rate of organ space SSI, superficial SSI, deep SSI, and mortality.
    OABP in combination with preoperative IVAP and within 24 h post-operation significantly reduced the incidence of SSI in intestinal surgery. Metronidazoles accompanied with quinolones or aminoglycosides might be the appropriate combinations for OABP regimens.

    Objective: To explore the efficacy and safety of enhanced recovery protocol (ERP) combined with laparoscopic appendectomy (LA) in the treatment of acute uncomplicated appendicitis (AUA) without antibiotics. Methods: In this study, a total of 160 patients with AUA who underwent LA between January 2018 and December 2021 were included and divided into the antibiotic group (n = 80) or the no-antibiotic group (n = 80). The patients in the antibiotic group received the ERP combined with antimicrobials during the perioperative period, while those in the no-antibiotic group only received the ERP during the perioperative period. The clinical data of these patients were collected to compare the inflammation level and stress state before and after surgery. In addition, the incidence of postoperative complications and the recovery speed of the patients were compared between groups. Results: There were no significant differences in the inflammation level and stress state before or after surgery, the incidence of postoperative complications or the recovery speed between the antibiotic group and the no-antibiotic group (P > .05). Conclusion: The use of ERP combined with LA as an antimicrobial-free treatment scheme in the perioperative period was found to be safe and effective for patients with AUA. Therefore, this approach is clinically valuable.

    通过间隙连接通道的细胞间通讯对于协调所有多细胞生物组织中细胞的功能非常重要。它允许离子和小分子(包括第二信使,如Ca2+,IP3,环核苷酸,和寡核苷酸)。在这项研究中,从Sebastesschlegerelii中鉴定出间隙连接(GJ)蛋白家族的48个成员。在S.schlegelii,GJ蛋白分为两种类型,连接蛋白,还有Pannexin,然后连接蛋白被分成五个亚家族。通过系统发育分析和同位分析验证了48个基因的命名。连接蛋白含有四个跨膜片段和两个胞外环,胞内环和C末端的长度完全不同,翻译后修饰后,C端区域高度可变。PPI分析表明,GJ与紧密连接相互作用,粘合接头,和细胞粘附形成复杂的网络,并参与细胞-细胞连接组织,ATP结合,离子通道,电压门控传导,Wnt信号通路,Fc-γ受体信号通路,和DNA复制。此外,S.schlegeliiGJ蛋白在肠组织中高表达,并在爱德华氏菌和链球菌感染后受到显着调节。LPS和poly(I:C)显著调控了施乐氏链球菌肠细胞GJs的表达,这与病原体刺激肠道组织的结果一致。总之,本研究为进一步研究SchlegeliiGJ蛋白的功能提供了有价值的信息。
    Cell-to-cell communication through gap junction channels is very important to coordinate the functions of cells in all multicellular biological tissues. It allows the direct exchange of ions and small molecules (including second messengers, such as Ca2+, IP3, cyclic nucleotides, and oligonucleotides). In this study, a total of 48 members of the gap junction (GJ) protein family were identified from Sebastes schlegelii. In S. schlegelii, GJ proteins were classified into two types, connexin, and pannexin, and then connexins were divided into five subfamilies. The naming of 48 genes was verified through phylogenetic analysis and syntenic analysis. The connexin proteins contained four transmembrane fragments and two extracellular loops, the lengths of the intracellular loop and C-terminal was quite different, and the C-terminal region was highly variable after post-translational modification. PPI analysis showed that GJs interacted with tight junctions, adhesive junctions, and cell adhesions to form a complex network and participated in cell-cell junction organization, ATP binding, ion channel, voltage-gated conduction, wnt signaling pathway, Fc-γ receptor signaling pathway, and DNA replication. In addition, the S. schlegelii GJ protein was highly expressed in intestinal tissues and remarkably regulated after Edwardsiella tarda and Streptococcus iniae infection. The expression of GJs in intestinal cells of S. schlegelii was significantly regulated by LPS and poly (I:C), which was consistent with the results of intestinal tissue stimulation by pathogens. In conclusion, this study can provide valuable information for further research on the function of S. schlegelii GJ proteins.

    目的:通过应力应变指数(SSI)图评估圆锥角膜(KC)进展的局部角膜生物力学恶化。方法:评估29例接受角膜交联(CXL)的进行性KC患者的术前检查。检查包括由PentacamHR和CorvisST(Oculus,Wetzlar,德国),分别。结果记录了两次,后者是在CXL手术前的最后一次访视.建立了患者特定的SSI图,使用每次检查的数据,基于有限元建模,并采用反分析来表示整个角膜的生物力学刚度的区域变化。结果:所有病例在前后曲率和最小厚度方面均表现出显着的形状进展(可重复性高于95%CI)。从第一次检查到最后一次检查,通过中心8mm直径区域内的SSI测量的总体角膜硬度略有但显着降低(-0.02±0.02,范围:-0.09至0,p<0.001)。在所有29个案例中,刚度的降低是局部的,并且集中在圆锥角膜内的区域。在最后一次检查中,锥体内部的SSI值显着降低(0.15±0.09,范围:-0.42至-0.01,p<0.001),而锥体外的SSI最小,无显著性差异(0±0.01,范围:-0.04至0.01,p=0.999)。结论:通过SSI图观察到,在病理区域内,僵硬的区域恶化是一致的,而在病理区域之外仅观察到轻度的非显著改变。
    Purpose: To evaluate the regional corneal biomechanical deterioration with keratoconus (KC) progression as measured by the Stress-Strain Index (SSI) maps. Methods: The preoperative examinations of 29 progressive KC cases that were submitted to corneal cross-linking (CXL) were evaluated. The examinations included the tomography and the SSI measured by the Pentacam HR and the Corvis ST (Oculus, Wetzlar, Germany), respectively. The results were recorded twice, the latter of which was at the last visit before the CXL procedure. The patient-specific SSI maps were built, using data at each examination, based on finite element modelling and employing inverse analysis to represent the regional variation of biomechanical stiffness across the cornea. Results: All cases presented significant shape progression (above the 95% CI of repeatability) in anterior and posterior curvatures and minimum thickness. The overall corneal stiffness as measured by the SSI within the central 8 mm-diameter area underwent slight but significant reductions from the first to the last examination (-0.02 ± 0.02, range: -0.09 to 0, p < 0.001). In all 29 cases, the reduction in stiffness was localised and concentred in the area inside the keratoconus cone. The SSI values inside the cone were significantly lower in the last examination (by 0.15 ± 0.09, range: -0.42 to -0.01, p < 0.001), while the SSI outside the cone presented minimal, non-significant variations (0 ± 0.01, range: -0.04 to 0.01, p = 0.999). Conclusion: It has been observed through the SSI maps that the regional deterioration in stiffness was concerted inside the area of pathology, while only mild non-significant alterations were observed outside the area of pathology.

    马歇尔·麦克卢汉曾提出“地球村”的概念,“相信在电子媒体的帮助下,地球已经变得与一个社区无法区分,人类只有一个地球,所有国家只有一个世界。今天,随着媒体技术的不断发展,人类命运共同体的概念也得到了世界各国人民的普遍共识。人类命运共同体的全球价值包含了相互依存的国际大国概念,共同利益的概念,可持续发展的概念,以及全球治理的概念。特别是,公众倡导可持续发展和全球治理的概念,这反过来又引起了公众对社会科学问题(SSI)的广泛讨论,其中SSI的教学逐渐被国际科学教育界视为科学教育的重要目标之一。SSI教学面临的当前问题和挑战以及沉浸式媒体技术如何促进SSI教学已成为公众感兴趣的重要问题。
    Marshall McLuhan once proposed the concept of \"global village,\" believing that with the help of electronic media, Earth has become indistinguishable from a community, and there is only one Earth for human beings and one world for all countries. Today, with the continuous development of media technology, the concept of a human destiny community has also gained the general consensus of people around the world. The global value of the human destiny community encompasses the interdependent concept of international power, the concept of common interests, the concept of sustainable development, and the concept of global governance. In particular, the concepts of sustainable development and global governance have been advocated by the public, which in turn has led to extensive public discussions on Socioscientific Issues (SSI), in which the teaching of SSI is gradually considered by the international science education community as one of the important goals of science education. The current issues and challenges facing SSI teaching and how immersive media technologies can facilitate SSI teaching have become important issues of keen public interest.

    评估体内圆锥角膜进展引起的生物力学恶化。
    对接受角膜交联的32例进展性KC患者的术前检查进行了评估。检查包括使用PentacamHR的角膜断层扫描和CorvisST评估的生物力学参数(Oculus,Wetzlar,德国)。在两个时间点记录结果,后者是在CXL手术前的最后一次访视.圆锥角膜进展的特征是ABCD系统的显着变化。
    在最后一次随访(41.4±40.9个月)时,ABCD分级系统的所有形态参数均显示出显着恶化(p<0.001)。比较分析显示,通过应力-应变指数的显着降低(SSI:-0.10±0.06,p<0.001),刚度参数A1(SP-A1:-6.1±12.0mmHg/mm,p=0.011),积分反向半径(IIR:0.95±1.04mm-1,p<0.001)和偏转幅度(DA)比(0.23±0.58,p=0.034)显着增加。DA的几乎没有显着增加也表明角膜僵硬度降低。(0.04±0.13mm,p=0.056)。SSI和IIR是两次检查之间重叠最小的指标。
    在体内已经证明,角膜生物力学恶化伴随圆锥角膜的发展而发生。与其余生物力学参数相比,在SSI和IIR中观察到的较大变化表明,这些参数可能适用于评估圆锥角膜自然进展中的角膜硬度降低。
    To assess the biomechanical deterioration arising from keratoconus progression in-vivo.
    The preoperative examinations of 32 progressive KC cases that were submitted to corneal cross-linking were evaluated. The examinations included the corneal tomography using the Pentacam HR and biomechanical parameters assessed by the Corvis ST (Oculus, Wetzlar, Germany). The results were recorded at two time points, the latter of which was at the last visit before the CXL procedure. Keratoconus progression was characterised by a significant change in the ABCD system.
    At the last follow-up visit (41.4 ± 40.9 months) all morphological parameters of the ABCD grading system showed significant deterioration (p < 0.001). The comparative analyses revealed a significant reduction in corneal stiffness expressed by a significant reduction in the stress-strain index (SSI: -0.10 ± 0.06, p < 0.001), the Stiffness parameter A1 (SP-A1: -6.1 ± 12.0 mmHg/mm, p = 0.011), by a significant increase in the integrated Inverse Radius (IIR: 0.95 ± 1.04 mm-1, p < 0.001) and in the deflection amplitude (DA) ratio (0.23 ± 0.58, p = 0.034). A barely significant increase in the DA also pointed towards corneal stiffness reduction. (0.04 ± 0.13 mm, p = 0.056). The SSI and the IIR were the indices with the smallest overlaps between the two examinations.
    It has been demonstrated in-vivo that corneal biomechanical deterioration occurs with keratoconus progression. The larger changes observed in the SSI and the IIR when compared to the remaining biomechanical parameters suggests that these parameters could be suitable to assess the corneal stiffness reduction in keratoconus natural progression.

    目的:评估预防性负压伤口治疗(pNPWT)预防手术部位感染(SSI)的疗效。腹侧疝修补术(VHR)后闭合性剖腹手术切口后疝复发和其他伤口并发症。
    方法:对PubMed,Cochrane中央受控试验登记册,Embase和ClinicalTrials.gov数据库从开始到2021年6月30日进行,以确定所有在线英文出版物,比较使用pNPWT和标准敷料在VHR后进行剖腹切开手术。
    结果:一项RCT和11项回顾性队列研究,涉及1355例患者,符合基本纳入标准。使用pNPWT降低了SSI(OR=0.39[95%CI:0.24-0.62]P<0.0001)和手术部位发生率(SSO)(OR=0.51[95%CI:0.27-0.98]P=0.04)。两组患者的疝复发率差异无统计学意义(OR=0.61[95%CI:0.30-1.26]P=0.18),血清肿(OR=0.70[95%CI:0.48-1.03]P=0.07),血肿(OR=0.77[95%CI:0.33-1.81]P=0.55)和伤口裂开(OR=0.68[95%CI:0.43-1.08]P=0.10)。
    结论:将pNPWT用于腹侧疝修补术后开腹手术切口可显著降低术后手术部位感染率(尤其是浅表SIS)和手术部位发生率。预防一次SSI发生所需治疗(NNT)的人数为9名患者。然而,需要进一步的研究和更高质量的研究来评估有效性并帮助阐明pNPWT在腹侧疝修补术后闭合性剖腹手术切口中的作用,优先在发生SSI的高危人群中。
    OBJECTIVE: To evaluate the efficacy of prophylactic negative pressure wound therapy (pNPWT) in preventing surgical site infection (SSI), hernia recurrence and other wound complications following closed laparotomy incisions following ventral hernia repair (VHR).
    METHODS: A comprehensive literature search of PubMed, the Cochrane Central Register of Controlled Trials, Embase and ClinicalTrials.gov databases was performed from inception until June 30, 2021, to identify all online English publications comparing the use of pNPWT with standard dressing for closed laparotomy incision following VHR.
    RESULTS: One RCT and eleven retrospective cohort studies involving 1355 patients satisfied the basic inclusion criteria. The use of pNPWT reduced SSI (OR = 0.39 [95% CI: 0.24-0.62] P < 0.0001) and surgical site occurrence (SSO) (OR = 0.51 [95% CI: 0.27-0.98] P = 0.04). No statistically significant difference was detected in the incidence of hernia recurrence (OR = 0.61 [95% CI: 0.30-1.26] P = 0.18), seroma (OR = 0.70 [95% CI: 0.48-1.03]P = 0.07), hematoma (OR = 0.77 [95% CI: 0.33-1.81]P = 0.55) and wound dehiscence (OR = 0.68 [95% CI: 0.43-1.08]P = 0.10).
    CONCLUSIONS: Use of pNPWT for closed laparotomy incisions following ventral hernia repair can significantly reduce the rate of postoperative surgical site infection (especially for superficial SIS) and surgical site occurrences. The number needed to treat (NNT) for preventing one occurrence of SSI is 9 patients. However, further research and more high quality studies are required to assess the effectiveness and assist in clarifying the role of pNPWT for closed laparotomy incisions following ventral hernia repair, preferentially in high-risk populations of developing SSI.
