PHD finger protein 19 (PHF19) is an epigenetic regulator known to be associated with the prognosis of patients in various tumours, while its impact on the prognosis of diffuse large B-cell lymphoma (DLBCL) remains unexplored. This study aimed to investigate the expression and prognostic significance of PHF19 in DLBCL. PHF19 expression was assessed in 192 DLBCL cases using immunohistochemistry. Correlations between PHF19 expression and clinicopathological parameters were analysed. Survival analysis was performed in patients receiving an anthracycline-based regimen with rituximab. The intensity of PHF19 protein expression in DLBCLs was significantly higher than that in normal lymph nodes. PHF19 expression was observed in 175 of 192 (91.1%) DLBCL cases, and 78 cases (78/192, 40.6%) were classified as PHF19 high expression. A high PHF19 expression correlated positively with Ann Arbor stages III–IV. In the cohort receiving an anthracycline-based regimen with rituximab, the 10-year overall survival (OS) rate and progression-free survival (PFS) rate were 86.0% and 58.0%, respectively. Compared with the PHF19 low-expression group, patients in the PHF19 high-expression group demonstrated significantly inferior OS and PFS. The multivariate analysis confirmed that a high level of PHF19 expression was an independent risk factor for inferior PFS, irrespective of Ann Arbor stage, B symptoms, Eastern Cooperative Oncology Group (ECOG) scores, International Prognostic Index (IPI) scores, and germinal centre B-cell (GCB) subtype. In conclusion, PHF19 was frequently expressed in DLBCL and high levels of PHF19 expression predicted an adverse outcome in DLBCL. Furthermore, the internal mechanisms of PHF19 involving proliferation and interactions with other genes need exploration in future studies.
PHD指蛋白19 (PHF19)是一种表观遗传调控因子,已知与多种肿瘤患者的预后相关,但其对弥漫性大b细胞淋巴瘤(DLBCL)预后的影响尚不清楚。本研究旨在探讨PHF19在DLBCL中的表达及其预后意义。应用免疫组化技术检测192例DLBCL患者中PHF19的表达。分析PHF19表达与临床病理参数的相关性。对接受以蒽环类药物为基础的利妥昔单抗方案的患者进行生存分析。PHF19蛋白在dlbcl中的表达强度明显高于正常淋巴结。192例DLBCL中有175例(91.1%)表达PHF19,其中78例(78/192,40.6%)为PHF19高表达。PHF19高表达与Ann Arbor III-IV期呈正相关。在接受蒽环类药物联合利妥昔单抗方案的队列中,10年总生存率(OS)和无进展生存率(PFS)分别为86.0%和58.0%。与PHF19低表达组相比,PHF19高表达组患者的OS和PFS明显低于低表达组。多因素分析证实,高水平的PHF19表达是不良PFS的独立危险因素,与Ann Arbor分期、B症状、东部肿瘤合作组(ECOG)评分、国际预后指数(IPI)评分和生发中心B细胞(GCB)亚型无关。总之,PHF19在DLBCL中频繁表达,高水平的PHF19表达预示着DLBCL的不良结局。此外,PHF19的增殖及与其他基因相互作用的内部机制还有待进一步研究。

CD47 is an important immune checkpoint in haematopoietic and solid malignancies. However, panreactivity of anti-CD47 agents leads to interference during pretransfusion compatibility testing binding to red blood cells. To address this issue, we created immunomagnetic beads (IMBs) to adsorb anti-CD47 monoclonal antibodies (mAbs): IMB-OVCAR3, coated with lysed protein from the OVCAR3 cell line, which was screened using flow cytometry and immunofluorescence staining, and IMB-CD47, coated with a recombinant CD47 protein. Plasma adsorbed by IMBs was collected for gel column agglutination testing and flow cytometry to verify elimination of anti-CD47 mAb interference. The effects of IMBs on irregular antibody screening and adsorption ability of IMBs over preservation time were also analysed. Following successful preparation, IMBs were shown to adsorb anti-CD47 mAb in plasma and reduce anti-CD47 mAb interference of simulated and clinical samples in 30 ​s. Moreover, IMBs did not adsorb irregular antibodies. Both IMBs retained their anti-CD47 mAb adsorption capacity for 3 weeks in a preservation solution. IMB-OVCAR3 and IMB-CD47 can serve as novel tools for the efficient removal of CD47 interference during transfusion compatibility testing in transfusion laboratories.
CD47是造血和实体恶性肿瘤的重要免疫检查点。然而,抗cd47药物的全反应性导致输血前与红细胞结合的相容性测试受到干扰。为了解决这个问题,我们创建了免疫磁珠(IMBs)来吸附抗CD47单克隆抗体(mab): IMB-OVCAR3包被来自OVCAR3细胞系的裂解蛋白,通过流式细胞术和免疫荧光染色进行筛选,IMB-CD47包被重组CD47蛋白。收集经IMBs吸附的血浆进行凝胶柱凝集试验和流式细胞术验证抗cd47 mAb干扰的消除。分析了IMBs对不规则抗体筛选的影响以及IMBs在保存时间内的吸附能力。成功制备后,IMBs可在30 s内吸附血浆中的抗cd47单抗,并减少模拟样品和临床样品的抗cd47单抗干扰。此外,imb不吸附不规则抗体。两种IMBs在保存液中均保持其抗cd47 mAb吸附能力3周。IMB-OVCAR3和IMB-CD47可作为输血实验室输血相容性检测中有效去除CD47干扰的新工具。

Primary aldosteronism (PA) is the most common cause of endocrine hypertension. Current screening uses the plasma aldosterone-to-renin ratio (ARR) followed by confirmatory testing with one of several tests. The saline suppression test (SST) is widely used but contraindicated in patients with renal insufficiency or congestive heart failure. The captopril challenge test (CCT) offers a safe, inexpensive and convenient alternative to the SST, but diagnostic thresholds and reported accuracy vary between centres. Furthermore, none of the previous comparative studies have been carried out in low- and middle-income countries, where the affordability of the CCT may offer distinct advantages. This study aimed to evaluate the diagnostic accuracy of the CCT compared to the SST in a Bangladeshi population. In this prospective study, consecutive hypertensive patients with an ARR >50 ​pmol/mIU underwent both the SST and CCT. Using the SST as the reference standard, where plasma aldosterone concentration (PAC) post SST ≥170 ​pmol/L is considered diagnostic of PA, the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and negative and positive predictive values of different diagnostic criteria for the CCT were calculated. A total of 103 patients completed both confirmatory tests. The diagnostic accuracy of the post-captopril PAC at both 1 ​h and 2 ​h outperformed post-captopril ARR or the percentage suppression of PAC (AUC 0.77, 0.70 and 0.56, respectively; p<0.001). PACs >333 ​pmol/L at 1 ​h and 2 ​h post administration of captopril demonstrated sensitivities of 54.5% and 44.4%, with specificities of 91.5% and 93.6%, respectively. A post-captopril PAC <151 ​pmol/L effectively ruled out PA with 96.4% sensitivity, while a PAC >380 ​pmol/L ruled in the diagnosis of PA with 95.7% specificity. Overall, our findings indicate that the CCT, based on post-captopril PAC, achieves comparable diagnostic accuracy to the seated SST. The diagnostic performance was similar at either 1 ​h or 2 ​h post administration of captopril, suggesting that 1 ​h may be preferred in a CCT protocol for efficiency. The CCT represents a safe and convenient confirmatory test to guide decisions on PA subtyping or medical treatment, especially in resource-limited settings.
原发性醛固酮增多症(PA)是内分泌性高血压最常见的病因。目前的筛查方法是血浆醛固酮与肾素比值(ARR),然后采用几种测试中的一种进行确认性测试。生理盐水抑制试验(SST)广泛应用于肾功能不全或充血性心力衰竭的患者,但禁用。卡托普利激发试验(CCT)为SST提供了一种安全、廉价和方便的替代方法,但各中心的诊断阈值和报告的准确性各不相同。此外,以前的比较研究都没有在低收入和中等收入国家进行,在这些国家,有条件现金转移支付的可负担性可能提供明显的优势。本研究旨在评估CCT与SST在孟加拉国人群中的诊断准确性。在这项前瞻性研究中,ARR为50 pmol/mIU的连续高血压患者同时接受SST和CCT。以SST为参考标准,以SST后血浆醛固酮浓度(PAC)≥170 pmol/L为PA诊断标准,计算CCT不同诊断标准的受试者工作特征曲线下面积(AUC)、敏感性、特异性和阴性、阳性预测值。共有103名患者完成了两项确认性检测。卡托普利治疗后1 h和2 h PAC的诊断准确性优于卡托普利治疗后ARR或PAC抑制百分比(AUC分别为0.77、0.70和0.56);卡托普利给药后1 h和2 h对p333 pmol/L的敏感性分别为54.5%和44.4%,特异性分别为91.5%和93.6%。卡托普利后pac380 pmol/L诊断PA的特异性为95.7%。总的来说,我们的研究结果表明,基于卡托普利后PAC的CCT与坐式SST的诊断准确性相当。卡托普利给药后1小时或2小时的诊断表现相似,表明在CCT方案中,1小时可能更有效。CCT是一种安全、方便的确证试验,可指导对PA亚型或医疗的决策,特别是在资源有限的情况下。

Infective endocarditis (IE) can be difficult to diagnose due to non-specific symptoms and the imperfect sensitivity of blood cultures and echocardiography. The interval between blood culture collection and the first detection of bacterial growth is known as time-to-positivity (TTP) and is considered a proxy for bacterial load. Several studies have demonstrated a shorter TTP in staphylococcal IE compared to staphylococcal bacteraemia of other sources; however, evidence in enterococcal IE is limited. We characterise the relationship between blood culture TTP and a diagnosis of Enterococcus faecalis IE, along with the impact of demographic and patient-specific factors. Retrospective analysis was performed for patients with blood cultures growing E. faecalis at a single centre from 2017 to 2021. Exclusion criteria included polymicrobial growth, repeat/relapsed episodes of enterococcal bacteraemia and receipt of pre-blood culture antibiotics. TTP was compared between participants with and without a definite diagnosis of IE per the 2023 Duke-International Society for Cardiovascular Infectious Diseases criteria. Comparison was also made between participants with and without a clinical diagnosis of IE. After exclusions, 114 episodes of E. faecalis bacteraemia were identified. Twenty-seven (24%) had a definite diagnosis of IE. Nineteen of the 27 (70%) IE cases were left-sided, and three (11%) were device-related. One case of prosthetic valve endocarditis was included. Other infective sources included the urinary tract ​(37/114, 32%) or an unidentified source (34/114, 30%). Median TTP was shorter in bacteraemia of other sources than in Duke definite IE (10.6 vs 11.3 h), but was not statistically significant (p=0.07). The area under the receiver-operator characteristic curve for the ability of TTP to diagnose IE was 0.62. Median TTP was shorter in the clinical IE group than bacteraemia of other sources (10.0 vs 11.4 h); however, this difference was not significant (p=0.34). E. faecalis IE was not associated with a shorter TTP than bacteraemia of other sources in this study. Higher-quality evidence is required to inform the utility of TTP in this condition.
感染性心内膜炎(IE)可能难以诊断,由于非特异性症状和不完善的敏感性血培养和超声心动图。血培养收集和首次检测细菌生长之间的时间间隔称为阳性时间(TTP),被认为是细菌负荷的代表。一些研究表明,与其他来源的葡萄球菌性菌血症相比,葡萄球菌性IE的TTP较短;然而,肠球菌性IE的证据有限。我们描述了血培养TTP与粪肠球菌IE诊断之间的关系,以及人口统计学和患者特异性因素的影响。回顾性分析了2017年至2021年在单一中心进行血培养的粪肠球菌患者。排除标准包括多微生物生长、肠球菌菌血症重复/复发发作和接受血前培养抗生素。根据2023年杜克-国际心血管传染病学会的标准,比较有和没有明确诊断为IE的参与者之间的TTP。还对有和没有临床诊断为IE的参与者进行了比较。排除后,确定了114例粪肠杆菌菌血症。27例(24%)确诊为IE。27例IE中有19例(70%)为左侧,3例(11%)与设备相关。报告人工瓣膜心内膜炎1例。其他感染源包括尿路(37/ 114,32%)或不明来源(34/ 114,30%)。其他来源菌血症的中位TTP短于Duke明确IE (10.6 h vs 11.3 h),但无统计学意义(p=0.07)。TTP诊断IE的能力的受-操作者特征曲线下面积为0.62。临床IE组的中位TTP短于其他来源的菌血症(10.0 h vs 11.4 h);然而,这种差异不显著(p=0.34)。在本研究中,粪肠杆菌IE与其他来源的菌血症相比,与较短的TTP无关。在这种情况下,需要更高质量的证据来说明TTP的效用。

Exclusion criteria included polymicrobial growth, repeat/relapsed episodes of enterococcal bacteraemia and receipt of pre-blood culture antibiotics. TTP was compared between participants with and without a definite diagnosis of IE per the 2023 Duke-International Society for Cardiovascular Infectious Diseases criteria. Comparison was also made between participants with and without a clinical diagnosis of IE. After exclusions, 114 episodes of <em>E. faecalis</em><span><span> bacteraemia were identified. Twenty-seven (24%) had a definite diagnosis of IE. Nineteen of the 27 (70%) IE cases were left-sided, and three (11%) were device-related. One case of prosthetic valve endocarditis was included. Other infective sources included the </span>urinary tract ​(37/114, 32%) or an unidentified source (34/114, 30%). Median TTP was shorter in bacteraemia of other sources than in Duke definite IE (10.6 vs 11.3 h), but was not statistically significant (</span><em>p</em>=0.07). The area under the receiver-operator characteristic curve for the ability of TTP to diagnose IE was 0.62. Median TTP was shorter in the clinical IE group than bacteraemia of other sources (10.0 vs 11.4 h); however, this difference was not significant (<em>p</em>=0.34). <em>E. faecalis</em> IE was not associated with a shorter TTP than bacteraemia of other sources in this study. Higher-quality evidence is required to inform the utility of TTP in this condition.</div></div>","PeriodicalId":19915,"journal":{"name":"Pathology","volume":"57 7","pages":"Pages 932-935"},"PeriodicalIF":3.0,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144541829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to investigate the prognostic value of high-grade patterns (HGPs) in lymph node metastasis in lung adenocarcinoma (LUAD). We retrospectively analysed patients (n=345; 2016–2018) with pathological stage IIB–IIIB LUAD who underwent lobectomy. We evaluated the overall survival (OS) and recurrence-free survival (RFS) of patients with and without a micropapillary/solid pattern in the primary tumour and lymph node metastases. Among the patients, the median age was 61.0 years, 54.2% (n=187) were female and 36.5% (n=126) had a history of smoking. Among the involved lymph nodes, 70.4% (n=243) were in pN2 stage and 29.6% (n=102) were in pN1 stage. Of the patients, 32.8% (n=113) had only one lymph node metastasis at the N2 station, whereas 37.7% (n=130) had multiple lymph node metastases at the N2 station. Patients with vascular invasion (p=0.003), pN2 stage (p<0.001), and a predominantly solid histological pattern in the primary tumour (p<0.001) were more likely to have metastatic lymph nodes of the solid subtype. Using a cut-off value of 10% rather than 20%, HGPs were more significant in evaluating RFS (p<0.001 vs p=0.22) and OS (p=0.009 vs p=0.46). Compared to patients without HGPs in lymph node metastases, the presence of a solid component [hazard ratio (HR) 2.07, 95% confidence interval (CI) 1.27–3.38; p=0.004], micropapillary component (HR 3.20, 95% CI 1.81–5.68; p<0.001), and both solid and micropapillary components (HR 2.60, 95% CI 1.54–4.40; p<0.001) in lymph node metastasis were all significantly associated with poorer OS. Patients with only micropapillary components (HR 1.96, 95% CI 1.19–3.22; p=0.008) or both micropapillary and solid components (HR 1.75, 95% CI 1.12–2.71; p=0.013) in lymph node metastasis had significantly poorer RFS. For surgically resected LUAD patients with lymph node metastasis, those with high-grade histological patterns in metastatic lymph nodes had a poorer prognosis, and the histological patterns of metastatic lymph nodes can be used to stratify such patients.
我们的目的是探讨肺腺癌(LUAD)淋巴结转移的高级别模式(HGPs)的预后价值。我们回顾性分析了患者(n=345;2016-2018),病理分期为IIB-IIIB期LUAD,行肺叶切除术。我们评估了原发肿瘤和淋巴结转移患者中有无微乳头状/实体型的总生存期(OS)和无复发生存期(RFS)。患者中位年龄为61.0岁,女性占54.2% (n=187),有吸烟史的占36.5% (n=126)。受累淋巴结中,70.4% (n=243)为pN2期,29.6% (n=102)为pN1期。32.8% (n=113)的患者N2站仅有一个淋巴结转移,而37.7% (n=130)的患者N2站有多个淋巴结转移。血管侵犯(p=0.003), pN2期(p=0.003)

Previous studies have reported a global increasing trend in the incidence of Hodgkin lymphoma (HL), especially among individuals who are female, of younger age and from Asian nations. However, detailed long-term trend analyses on individual countries and investigation of reasons for these temporal trends, including Epstein–Barr virus (EBV) association, are limited. We compared nationwide registration data from Taiwan and the USA during the interval 2001 through 2020 and used an age-period-cohort model to analyse individual effects of time period and birth cohort on the incidence trends. The incidence of HL in Taiwanese people was much lower than that in White Americans (7.39 vs 28.43 per million inhabitants). However, in contrast to a slightly decreased incidence rate in White Americans, HL in Taiwanese people showed a steadily increasing incidence rate during the 20-year interval (overall annual percentage change +2.82%), especially for women with nodular sclerosis subtype and aged 25–30 years, during the period 2011–2020. The prominent increase in relative risks was revealed by the time period and birth-cohort effects in Taiwanese people compared with White Americans. Interestingly, the linear trend test demonstrated a significant decrease in EBV association in Taiwanese HL over the 20-year period, from ∼60% to ∼20% (p=0.025), with a bimodal EBV-positive pattern in childhood (<10 years, 50%) and in older adults (>70 years, 93%). These findings suggest environmental influences and Westernisation of lifestyle in HL aetiology and that improvement of public health may influence the incidence and biological features of HL.
先前的研究报告了霍奇金淋巴瘤(HL)的全球发病率呈上升趋势,特别是在女性、年轻人和来自亚洲国家的个体中。然而,对个别国家的详细长期趋势分析和对这些暂时趋势的原因的调查,包括eb病毒(EBV)关联,是有限的。我们比较了2001年至2020年台湾和美国的全国登记数据,并使用年龄-时期-队列模型来分析时间和出生队列对发病率趋势的个体影响。台湾人的HL发病率远低于美国白人(7.39 vs 28.43 /百万)。然而,与美国白人的发病率略有下降相比,台湾人群的HL发病率在2011-2020年期间稳步上升(总体年百分比变化+2.82%),特别是25-30岁的结节硬化亚型女性。与美国白人相比,台湾人的相对风险显著增加是由时间和出生队列效应所揭示的。有趣的是,线性趋势检验显示,台湾HL患者EBV相关性在20年间显著下降,从60%降至20% (p=0.025),儿童期EBV呈双峰型阳性模式(70岁,93%)。这些发现表明,环境影响和生活方式西方化与HL病因学有关,公共卫生的改善可能影响HL的发病率和生物学特征。

Trichorhinophalangeal syndrome type 1; transcriptional repressor GATA binding 1 (TRPS1), a member of the GATA transcription factor family, functions primarily as a transcriptional repressor. TRPS1 is frequently utilised as a diagnostic marker for breast carcinoma, although its specificity is lower than previously believed. Moreover, TRPS1 is expressed in various solid tumours originating from the skin, salivary glands, soft tissues, prostate, urothelium, and female genital tract. The current study evaluated the diagnostic and prognostic significance of TRPS1 in 451 primary tubo-ovarian tumours. The cohort included 94 high-grade serous carcinomas (HGSCs), 81 low-grade serous carcinomas (LGSCs), 31 micropapillary serous borderline tumours (mSBTs), 92 clear cell carcinomas (CCCs), 52 endometrioid carcinomas (ECs), 31 mucinous carcinomas (MCs), and 70 mucinous borderline tumours (MBTs). Immunohistochemical analysis was performed using tissue microarrays following standardised protocols. Clinical data were analysed to determine the prognostic relevance of TRPS1 expression. TRPS1 expression was detected in 47% of HGSCs, 44% of ECs, 35% of CCCs, 19% of LGSCs, and 29% of mSBTs with complete negativity in MC/MBT. TRPS1-negative HGSC cases had higher recurrence rates than those with positive staining. Furthermore, TRPS1 expression significantly correlated with improved metastasis-free survival in HGSC cases. These findings suggest that TRPS1 may serve as an independent prognostic marker for HGSC. Despite varying expression rates across primary tubo-ovarian carcinomas, the routine use of TRPS1 in the differential diagnosis seems to be limited, ​as other robust immunohistochemical markers are available for distinguishing the individual subgroups. Further research is needed to clarify the specific functions and clinical implications of TRPS1 in tubo-ovarian cancer.
1型鼻棘毛综合征;转录抑制因子GATA结合1 (TRPS1)是GATA转录因子家族的成员,主要作为转录抑制因子发挥作用。TRPS1经常被用作乳腺癌的诊断标志物,尽管它的特异性比以前认为的要低。此外,TRPS1在来自皮肤、唾液腺、软组织、前列腺、尿路上皮和女性生殖道的各种实体肿瘤中表达。目前的研究评估了TRPS1在451例原发性输卵管卵巢肿瘤中的诊断和预后意义。该队列包括94例高级别浆液性癌(HGSCs)、81例低级别浆液性癌(LGSCs)、31例微乳头状浆液性交界性肿瘤(msbt)、92例透明细胞癌(CCCs)、52例子宫内膜样癌(ECs)、31例粘液性癌(MCs)和70例粘液性交界性肿瘤(mbt)。免疫组织化学分析采用组织微阵列按照标准化方案进行。分析临床数据以确定TRPS1表达与预后的相关性。TRPS1在47%的HGSCs、44%的ECs、35%的CCCs、19%的LGSCs和29%的MC/MBT完全阴性的msbt中检测到表达。trps1阴性HGSC病例的复发率高于阳性染色者。此外,TRPS1的表达与HGSC病例中无转移生存的改善显著相关。这些发现提示TRPS1可能作为HGSC的独立预后标志物。尽管原发性输卵管性卵巢癌的表达率不同,但常规使用TRPS1进行鉴别诊断似乎是有限的,因为其他强大的免疫组织化学标志物可用于区分单个亚群。TRPS1在输卵管性卵巢癌中的具体功能和临床意义有待进一步研究。
