This study investigates the relationship between immune cells and IPF using Mendelian randomization (MR) analysis.Methods: A two-sample MR analysis was performed using genome-wide association studies (GWAS) and immune cell databases by R software. We analyzed data from 1028 European individuals with IPF, focusing on 731 immune traits. The primary method of analysis was inverse variance weighting (IVW), supplemented with sensitivity analyses, including MR-Egger regression and MR-PRESSO, to detect and correct for pleiotropy.Results: The MR analysis identified six immune panels and 23 immune traits significantly associated with IPF, including five traits that increase and 18 traits that decrease IPF risk. Notable traits increasing IPF risk included switched memory B-cells (OR = 1.27, p = 0.0029) and IgD- CD38dim B-cells (OR = 1.08, p = 0.0449). Traits associated with a reduced IPF risk included central memory CD4+ T-cells (%CD4+, OR = 0.96, p = 0.0489), CD20 on naive-mature B-cells (OR = 0.94, p = 0.0499), and CD33br HLA-DR+ absolute count (AC) (OR = 0.93, p = 0.0489). There was no significant causal relationship between IPF disease and some immune traits (p > 0.05).Conclusion: This study suggests a potential causal link between specific immune cell traits and the development of IPF, providing new insights into the disease's immunological mechanisms. Future research should focus on validating these findings in larger, more diverse populations to inform drug development and therapeutic strategies.","PeriodicalId":15509,"journal":{"name":"Journal of Clinical Laboratory Analysis","volume":" ","pages":"e70026"},"PeriodicalIF":2.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143752947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the risk factors associated with DVT after traumatic lower limb fractures and to analyze their values in clinical practice.Methods: Patients were classified into DVT and Non-DVT groups based on the occurrence of DVT during the perioperative period. These data were statistically analyzed to screen for risk factors for DVT after traumatic lower limb fractures and to analyze thrombus regression 1 month after surgery.Results: DVT occurred in 39.29% (77/196) patients during the perioperative period. The incidence of DVT varied, with a high incidence of 46.67% for femoral neck/trochanteric fractures. Patients in the DVT group were characterized by older age, higher perioperative blood transfusion (both p < 0.001), higher fibrinogen (FIB) on admission (p < 0.001), significant postoperative Hb decline (p = 0.023) and higher D-D (p = 0.001).

Therefore, the purpose of our study is to evaluate the relationship between FT3 and HDL-C in patients with type 2 diabetes.Methods: From June 2022 to October 2023, 3011 patients with normal thyroid function and diagnosed with type 2 diabetes mellitus (T2DM) were collected continuously and non-selectively in a Chinese hospital. Then, we used a logistic regression model to explore the relationship between FT3 and HDL-C. Smooth curve fitting is used to identify the nonlinear relationship between FT3 and HDL-C.Results: After adjusting for the influence of relevant factors, FT3 and HDL-C were negatively correlated -0.02 (-0.04, -0.00; p = 0.0162). There is also a nonlinear relationship between FT3 and HDL-C, with an inflection point of 3.48 pmol/L for FT3 (P for log- likelihood ratio test = 0.044).Conclusion: This study shows that there is a negative correlation and nonlinear relationship between FT3 and HDL-C in the Chinese population with diabetes. When FT3 is between 2.76-3.48 pmol/L, HDL-C tends to a stable state; When FT3 is between 3.48-6.45 pmol/L, HDL-C decreases with the increase of FT3 concentration (According to the reference range used by our hospital, the normal value of serum FT3 is 2.76-6.45 pmol/L). These findings suggest that maintaining FT3 within the range of 2.76 to 3.48 pmol/L may be most beneficial for mitigating the progression of cardiovascular disease in patients with T2DM.","PeriodicalId":15509,"journal":{"name":"Journal of Clinical Laboratory Analysis","volume":" ","pages":"e70029"},"PeriodicalIF":2.6,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143730258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, microbiological diagnostic methods are available to accelerate microbiological diagnosis, thereby reducing the time needed to implement targeted antibiotic therapy. One method for rapid diagnosis is the amplified magnetic resonance imaging-T2 Biosystems, USA (T2Dx). This method enables the identification of pathogens directly from a blood sample (approximately 4 mL) within about 3.5 h. The use of the \"T2 Resistance\" panel additionally allows for the detection of the most common bacterial resistance mechanisms in about 4-5 h. The disadvantage of the T2Dx method is the limited number of microorganisms it can detect. The objective of the study was to evaluate the effectiveness of using selected inflammatory parameters to accurately qualify patients (positive result) for T2Dx testing.Methods: We have made a retrospective evaluation of selected inflammatory parameters in order to determine which parameters are the best indicators for good qualification of patients.Results and conclusion: A single analysis of parameters such as C-reactive protein (CRP), white blood cells (WBC), #neutr, #lymph, and neutrophil-to-lymphocyte ratio (NLR) is not a good indicator that could be used as an additional tool facilitating patient qualification for T2Dx testing. The most sensitive parameter distinguishing between patients with a positive T2Dx result and those with a negative result is the measurement of IL-6 and PCT. Proper patient qualification for T2Dx testing can significantly contribute to reducing the time to initiate targeted antibiotic therapy and may impact reducing mortality and improving long-term treatment outcomes.","PeriodicalId":15509,"journal":{"name":"Journal of Clinical Laboratory Analysis","volume":" ","pages":"e70021"},"PeriodicalIF":2.6,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143719454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genetic diagnostic centers (GDCs) play a critical role in this process but face numerous occupational health and safety (OHS) challenges. The classification of GDCs based solely on biosafety levels is insufficient for assessing their overall OHS conditions. This study aims to systematically evaluate OHS practices in GDCs and propose a new classification approach based on hazard dimensions.Methods: This cross-sectional study was conducted in 15 GDCs in Istanbul, including two public and 13 private facilities with 75 employees. Data were collected through a structured survey with 49 statements covering seven hazard dimensions. Regression and correlation analyses were used to assess the impacts and interrelationships of these dimensions on risk management. Principal Component Analysis (PCA) was applied for dimensionality reduction, and the k-Nearest Neighbours (k-NN) algorithm classified laboratories into safety levels.Results: Personal protective equipment had the highest impact on risk management (56.3%), while physical security had the lowest (34.8%). Among the 21 identified hazard relationships, 18 were very strong and three were strong. PCA reduced the data into three primary components, explaining 81.9% of the variance. The k-NN algorithm achieved a classification accuracy of 93.33%, consolidating six hazard dimensions into three and categorizing centers into three safety levels.Conclusion: The findings emphasize the need for an updated OHS classification for GDCs beyond biosafety levels. Integrating hazard dimensions into safety assessments can improve risk management and enhance laboratory safety standards.","PeriodicalId":15509,"journal":{"name":"Journal of Clinical Laboratory Analysis","volume":" ","pages":"e70015"},"PeriodicalIF":2.6,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143719389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
