Splenectomy has been linked to overwhelming sepsis and more recently to thromboembolic events (TEE) [<span>2-5</span>]. Danish national registry studies documented the increased occurrence of TEE postsplenectomy; however, earlier studies were restricted to males and later ones, including two Danish studies, did not discriminate TEE in women from those in men [<span>2-4</span>]. TEE risk differs between men and women in several ways [<span>5</span>], so sex-specific assessments are critical. Premenopausal women have a predisposition to TEE for several reasons including hormonal and autoimmune ones; however, TEE risk remains unclear in postmenopausal women. We therefore conducted a prospective cohort study within the Nurses' Health Study (NHS) using biennial questionnaires with medical record confirmation of thromboses to robustly assess association between splenectomy and TEE in postmenopausal women.</p><p>The NHS was established in 1976 and enrolled 121 700 female registered nurses between 30 and 55 years old. Splenectomy history was included on the 2004 questionnaire and 90 853 postmenopausal women (at that time between ages of 58 and 83 years) were included in the current analysis. The biennial questionnaires asked participants whether they had stroke, myocardial infarction (MI), deep vein thrombosis (DVT), or pulmonary emboli (PE) since cohort inception. Participants self-reporting TEE received letters requesting confirmatory medical records. Through 2012, questions about DVT and PE were distinct; subsequently, 2012–2016, participants were asked about both as a single outcome.</p><p>The primary outcomes included DVT, PE, stroke and MI, self-reported on biennial questionnaires. Follow-up for this nested cohort study started in 2004 after all splenectomies. End of follow-up was through the 2016 questionnaire, date of death, or diagnosis of outcome, whichever came first. Loss to follow-up in NHS is < 5% every 2-year cycle. Date and cause of death were obtained through linkage with the National Death Index. We conducted a prospective analyses (start from 2004) with Cox Proportional Hazard models to generate hazard ratios and 95% confidence intervals (CIs). We included the following covariates as potential confounders in multivariate models: (a) continuous variables: age, BMI, hypertension, and cholesterol level; and (b) yes/no variables: smoking status, physical activity, diabetes, and menopausal hormone therapy.</p><p>Biennial questionnaires did not include a specific question about reason for splenectomy. Participants had the option to report these diagnoses under “other illnesses.” They were then mapped to ICD-9 and ICD-10 disease codes including categorizing these conditions into definite ITP (codes = 287.31), and possible ITP (codes = 287.30).

Although clinical criteria are available for subtyping, diagnostically challenging cases with overlapping histopathological features highlight the need for an improved classification system integrating clinical and histopathological findings. We aimed to develop an objective histopathological subtyping system for iMCD that closely correlates with the clinical subtypes. Excisional lymph node specimens from 94 Japanese iMCD patients (54 IPL, 28 TAFRO, 12 NOS) were analyzed for five key histopathological parameters: germinal center (GC) status, plasmacytosis, vascularity, hemosiderin deposition, and “whirlpool” vessel formation in GC. Using hierarchical clustering, we visualized subgroups and developed a machine learning‐based decision tree to differentiate the clinical subtypes and validated it in an external cohort of 12 patients with iMCD. Hierarchical cluster analysis separated the IPL and TAFRO cases into mutually exclusive clusters, whereas the NOS cases were interspersed between them. Decision tree modeling identified plasmacytosis, vascularity, and whirlpool vessel formation as key features distinguishing IPL from TAFRO, achieving 91% and 92% accuracy in the training and test sets, respectively. External validation correctly classified all IPL and TAFRO cases, confirming the reproducibility of the system. Our histopathological classification system closely aligns with the clinical subtypes, offering a more precise approach to iMCD subtyping. It may enhance diagnostic accuracy, guide clinical decision‐making for predicting treatment response in challenging cases, and improve patient selection for future research. Further validation of its versatility and clinical utility is required.","PeriodicalId":7724,"journal":{"name":"American Journal of Hematology","volume":"45 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144334846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients undergoing allo‐HSCT were randomized on Day 3 Post‐Infusion into low‐dose (2.5 mg/day), high‐dose (5 mg/day) hetrombopag groups, or a control group receiving thrombopoietin (300 U/kg/day).

People ≥ 80 years old often have comorbidities and unfavorable disease characteristics (like unmutated IGHV and 17p deletion) associated with lower survival [&lt;span&gt;2&lt;/span&gt;]. Despite efforts to include advanced age in the eligibility criteria, landmark CLL clinical trials that led to the approval of ibrutinib and venetoclax primarily included participants &lt; 75 years old, making it challenging to apply their findings to older patients. To help close this knowledge gap, we conducted a multi-center retrospective cohort study with data spanning nearly three decades to describe treatment outcomes for patients treated for CLL in the frontline setting at ages ≥ 80 years.&lt;/p&gt;\u0000&lt;p&gt;Using the Mayo Clinic CLL Database and the Danish Lymphoid-lineage Cancer Research (DALY-CARE) data (Danish Cohort), we conducted a retrospective cohort study of patients who were ≥ 80 years old at the time of first CLL treatment between January 1995 and November 2022 (Mayo Clinic) and January 2008 and March 2022 (Denmark). The Mayo Clinic CLL Database contains records of consenting patients diagnosed with CLL who were seen at Mayo Clinic in Rochester, MN. The Danish Cohort includes all Danish citizens diagnosed with CLL, with data available from time of birth or immigration, enabled by linkage of personal-level data across national administrative and clinical quality registers using a unique personal identification number. We extracted information about clinical characteristics, patient demographics, and all lines of treatment (Table S1). We calculated overall survival (OS) from the date of first treatment to the date of death or date last known to be alive. OS was displayed using the Kaplan–Meier method. Time to next treatment (TTNT) was calculated from the date of first treatment to earliest date of (a) date of second treatment, (b) date of death, or (c) date last known to be alive. TTNT was visualized using the cumulative incidence method with competing risk of death. Univariable Cox proportional hazards models were used to analyze the association between type of treatment and time to events (i.e., OS or TTNT); results were reported as hazard ratios (HR) and 95% confidence intervals (CI). Analyses were conducted using statistical software SAS 9.4 (SAS Institute Inc., Cary, NC, USA) and R statistical software versions 4.2.0 and 4.3.2.
