Abstract
Peloidotherapy and aromatherapy have been used for years in the treatment of numerous inflammatory conditions, including rheumatoid arthritis (RA). The exact mechanism of their action in RA is unclear. The goal of our research is to determine the effect of peloidotherapy and aromatherapy on inflammation parameters in RA patients. Our study included 20 patients of both sexes, with confirmed diagnosis of RA, older than 18 years. Patients were treated during 28 days with combination of peloidotherapy and aromatherapy. Serum samples for detection of levels of inflammation parameters were taken at two intervals: before the start of therapy and at the end of treatment. The results of our study show that there were no significant changes in the parameters of the complete blood count. Nevertheless, a statistically significant decrease in the serum concentration of two markers of inflammation-interleukin-6 (IL-6) and nitrogen-oxide (NO)-was detected. Correlation analyses results say that there is a synchronized drop in the serum concentrations of CRP and the sedimentation rate, and the serum concentrations of fibrinogen and IL-6 are in the same relationship as well as serum levels of IL-6 and NO. Bearing in mind the importance of IL-6 and NO in the pathogenesis of inflammation in RA, we conclude that the application of our therapeutic protocol can be a significant add-on treatment to classic immunomodulators. Due to the small number of study participants, the lack of a control group, and the short follow-up time of patients, additional research is needed.

Abstract
BACKGROUND Chronic spontaneous urticaria (CSU) is an inflammatory skin disease with intricate mechanisms. This study comprehensively assessed markers from diverse metabolic pathways, including novel inflammatory indicators, to evaluate their potential for diagnosing and monitoring CSU. MATERIALS AND METHODS In the study involving 90 CSU patients and 90 healthy controls, the levels of albumin, high-density lipoprotein (HDL), fibrinogen, uric acid, D-dimer, C-reactive protein (CRP), and white blood cells (WBC) values were analyzed. The D-dimer/albumin ratio (DAR), fibrinogen/albumin ratio (FAR), and uric acid/HDL ratio (UHR), considered novel inflammatory markers, were calculated. The Urticaria Activity Score 7 (UAS7) was also calculated. Pearson chi-squared test, Mann-Whitney U test, Spearman correlation coefficient, and univariate logistic regression analysis were employed for data analysis. RESULTS In the patient group, significant elevations were observed in DAR, FAR, fibrinogen, CRP, D-dimer, and UHR values. Additionally, albumin, HDL, and uric acid values exhibited significant decreases. HDL and albumin provided the most accurate results in the univariate logistic regression analysis. CRP had less accuracy, FAR exhibited greater accuracy than fibrinogen, and DAR demonstrated higher accuracy than D-dimer. There was no statistically significant correlation between the UAS7 and parameters. The considerable correlation of CRP with other parameters, except D-dimer, was also remarkable. CONCLUSIONS Indicators from diverse metabolic pathways, including albumin, HDL, uric acid, fibrinogen, D-dimer, and CRP, can be valuable in assessing CSU. In particular, FAR and DAR are emerging as potential markers to consider in the assessment of CSU.

Abstract
BACKGROUND AND AIM Growing body of evidence consistently link obesity and inflammation, Although the direction of the association is still unclear. We aimed to investigate longitudinal associations of body anthropometric, composition and fat distribution parameters with inflammatory markers and vice versa. METHOD AND RESULTS We used data from 2464 individuals of the SHIP-TREND cohort with a median follow-up of 7 years. Linear regression models adjusted for confounders were used to analyze associations of standardized body composition markers derived from classic anthropometry, bioelectrical impedance analysis (BIA) and magnetic resonance imaging (MRI) at baseline with changes in inflammatory markers (C-reactive protein (CRP), white blood cell (WBC), fibrinogen) and vice versa. Higher level of anthropometric markers at baseline were associated with an increase in the change of inflammatory markers. A 13.5 cm higher waist circumference (WC), 16.0 kg body weight and 7.76 % relative fat mass (FM) at baseline was associated with a change in CRP of 0.52 mg/L (95 % confidence interval [CI]: 0.29 to 0.74), 0.51 mg/L (95 % CI: 0.29; 0.74) and 0.58 mg/L (95 % CI: 0.34; 0.82) respectively. Absolute FM showed the strongest association with changes in serum fibrinogen levels (β for 8.69 kg higher FM: 0.07 g/L; 95 % CI: 0.05; 0.09). Baseline inflammatory markers were only associated with changes in hip circumference. CONCLUSION Our study indicates the importance of anthropometric, body composition and fat distribution markers as a risk factor for the development of inflammation. To prevent inflammatory-related complications, important is to take measures against the development of obesity.

Abstract
Respiratory syncytial virus (RSV) is a common cause of respiratory infections. It is responsible for more than half of lower respiratory tract infections in infants requiring hospitalization. This study aimed to investigate the correlation between the fibrinogen-albumin ratio (FAR) and the severity of RSV infection and to compare its effectiveness with the neutrophil-lymphocyte ratio (NLR). This was a retrospective cohort study with patients aged from 29 days to two years who had been admitted to the pediatric clinic of our hospital. Patients were divided into four groups: group 1 (mild disease), group 2 (moderate disease), group 3 (severe disease), and group 4 (control). FAR and NLR were measured in all groups. FAR was significantly higher in group 3 than in the other groups, in group 2 than in groups 1 and 4, and in group 1 than in group 4 (p<0.001 for all). NLR was significantly higher in group 4 than in the other groups and in group 3 than in groups 1 and 2 (p<0.001 for all). FAR totaled 0.078 ± 0.013 in patients with bronchiolitis; 0.099 ± 0.028, in patients with bronchopneumonia; and 0.126 ± 0.036, in patients with lobar pneumonia, all with statistically significant differences (p<0.001). NLR showed no significant statistical differences. This study found a statistically significant increase in FAR in the group receiving invasive support when compared to that receiving non-invasive support (0.189 ± 0.046 vs. 0.112 ± 0.030; p=0.003). Mechanical ventilation groups showed no differences for NLR. FAR was used to identify severe RSV-positive patients, with a sensitivity of 84.4%, a specificity of 82.2%, and a cutoff value of >0.068. This study determined a cutoff value of ≤1.49 for NLR, with a sensitivity of 62.2% and a specificity of 62.2% to find severe RSV-positive patients. Also, statistically significant associations were found between FAR and hospitalization and treatment length and time up to clinical improvement (p<0.001 for all). NLR and hospitalization and treatment length showed a weak association (p<0.001). In children with RSV infection, FAR could serve to determine disease severity and prognosis and average lengths of hospitalization, treatment, and clinical improvement. Additionally, FAR predicted disease severity more efficiently than NLR.

Abstract
PURPOSE This study aimed to examine the association of fibrinogen/fibrin degradation product (FDP) values in comparison with D-dimer and fibrinogen (Fib) values and the need for massive fresh frozen plasma (FFP) transfusion in patients with blunt trauma. METHODS This retrospective study included patients with blunt trauma aged ≥ 18 years who were transported directly to the tertiary care hospital between April, 2012, and March, 2021. Massive FFP transfusion was defined as a composite outcome of at least 10 units of FFP or death for any cause except for cerebral herniation, within 24 h after hospital arrival. We evaluated the diagnostic accuracy of predicting the need for massive FFP transfusions using FDP, D-dimer, and Fib levels at the time of hospital arrival. RESULTS A total of 2160 patients were eligible for the analysis, of which 167 fulfilled the criteria for the composite outcome. The area under the curve and 95% confidence interval for FDP, D-dimer, and Fib levels were 0.886 (0.865-0.906), 0.885 (0.865-0.906), and 0.771 (0.731-0.810), respectively. When the cutoff values of FDP and D-dimer were set at 90 μg/mL and 45 μg/mL, the sensitivity values were 77% and 78%, the positive predictive values were 28% and 27%, and the negative predictive values were both 98%, respectively. In contrast, the sensitivity of Fib was low regardless of the cutoff value. CONCLUSION FDP and D-dimer levels at the time of hospital arrival showed a higher predictive accuracy for the need for massive FFP transfusion than Fib.

Abstract
BACKGROUND Tigecycline-associated hypofibrinogenemia has been reported as an important adverse effect in recent years, but controlled studies minimizing confounding factors are needed. The objective of our study was to assess changes in fibrinogen levels in patients for hospitalization, comparing two antibiotic episodes (tigecycline and other) within the same patients. METHODS The retrospective, self-controlled case series study was conducted at our University Hospitals. The study compared the change in fibrinogen levels during the patient's hospitalization for tigecycline (TigePer) and another antibiotic period (OtherPer). In addition, bleeding events, bleeding risk (determined by the IMPROVE bleeding risk score), as well as 15- and 30-day mortality rates between TigePer and OtherPer were compared. RESULTS The study enrolled 50 patients with 100 episodes of antibiotic treatment. The median age (interquartile range) of the patients was 68.5 (21.5) years, and 38 % were female. As compared to OtherPer, TigePer had a statistically significant reduction in fibrinogen levels (p < 0.001), with a hypofibrinogenemia rate of 40 % in TigePer as compared to 2 % in OtherPer (p < 0.001). TigePer demonstrated a significantly higher 15-day mortality rate (p = 0.006). No significant differences were observed between the two periods in terms of bleeding risk, rate of bleeding events, and 30-day mortality rate (p > 0.05). CONCLUSION Hypofibrinogenemia and other coagulopathies, without associated bleeding events, are more frequently observed in patients receiving tigecycline. Therefore, it is crucial for clinicians to monitor fibrinogen levels during tigecycline use.

Abstract
OBJECTIVE To analyze the prognostic nutritional index (PNI), controlling nutritional status (CONUT) and fibrinogen/albumin ratio (FAR) levels in elderly patients with multiple myeloma (MM) and their prognostic impact. METHODS The clinical data of 74 elderly MM patients diagnosed in Gansu Provincial Hospital from January 2020 to July 2022 were retrospectively analyzed. The optimal cut-off values for PNI, CONUT score and FAR were obtained by receiver operating characteristic (ROC) curve, which were used for grouping patients. The correlation of above three indexes with clinical parameters such as sex, serum calcium (Ca), β2-microglobulin (β2-MG), serum creatinine (Cr) in elderly MM patients were analyzed. The survival rates of patients with different levels of each index were compared. Univariate and multivariate analysis of the impact of clinical indicators on the prognosis of patients were performed. RESULTS The optimal cut-off values for PNI, CONUT score and FAR were 39.775, 3.5 and 0.175, respectively, according to which the patients were divided into high and low group. Statistical analysis showed that there were significant differences in albumin level among different groups (all P < 0.05). In addition, there was a significant difference in hemoglobin between high-PNI group and low-PNI group (P < 0.05), while in sex distribution between high-FAR and low-FAR group (P < 0.05). The survival rate of elderly MM patients with increased PNI, decreased CONUT score and FAR was higher (all P < 0.05). Univariate and multivariate analysis showed that β2-MG, Cr, PNI, CONUT score and FAR were independent prognostic factors for elderly MM patients. CONCLUSION PNI, CONUT score and FAR are related to some clinical indicators of elderly MM patients, and have an impact on the prognosis.

Abstract
BACKGROUND Hormone replacement therapy is associated with an increased thromboembolic risk. The effects of testosterone (T) on coagulation markers in people assigned female at birth (AFAB) under gender affirming hormone therapy (GAHT) are not well described. METHODS Systematic review and meta-analysis on English-language articles retrieved from PubMed, Scopus and Cochrane Library up to April 2023 investigating T therapy in AFAB people. Coagulation parameters included international normalized ratio (INR), fibrinogen, activated partial thromboplastin clotting time (aPTT), plasminogen activator inhibitor-1 (PAI-1); hematological variables included hemoglobin (Hb) and hematocrit (HCT). We also reported the rate of thromboembolic events. Data were combined as mean differences (MD) with a 95 % confidence interval (CI) of pre- vs post-follow-up values, using random-effects models. RESULTS We included 7 studies (6 prospective and 1 retrospective) providing information on 312 subjects (mean age: 23 to 30 years) who underwent GAHT with variable T preparation. T therapy was associated with a significant increase in INR values [MD: 0.02, 95 % confidence interval (CI): 0.01-0.03; p = 0.0001], with negligible heterogeneity (I2 = 4 %). T therapy was associated with increased Hb (MD: 1.48 g/dL, 95%CI: 1.17 to 1.78; I2 = 9 %) and HCT (4.39 %, 95%CI: 3.52 to 5.26; I2 = 23 %) values. No effect on fibrinogen, aPTT and PAI-1 was found. None of the study reported thromboembolic events during the follow-up. CONCLUSION Therapy with T increased blood viscosity in AFAB men. A slight increase in INR values was also found, but the clinical relevance and mechanism(s) of this finding needs to be clarified.

Abstract
BACKGROUND Thrombolytic recombinant tissue plasminogen activator (r-tPA) treatment is the only pharmacologic intervention available in the ischemic stroke acute phase. This treatment is associated with an increased risk of intracerebral hemorrhages, known as hemorrhagic transformations (HTs), which worsen the patient's prognosis. OBJECTIVES To investigate the association between genetically determined natural hemostatic factors' levels and increased risk of HT after r-tPA treatment. METHODS Using data from genome-wide association studies on the risk of HT after r-tPA treatment and data on 7 hemostatic factors (factor [F]VII, FVIII, von Willebrand factor [VWF], FXI, fibrinogen, plasminogen activator inhibitor-1, and tissue plasminogen activator), we performed local and global genetic correlation estimation multitrait analyses and colocalization and 2-sample Mendelian randomization analyses between hemostatic factors and HT. RESULTS Local correlations identified a genomic region on chromosome 16 with shared covariance: fibrinogen-HT, P = 2.45 × 10-11. Multitrait analysis between fibrinogen-HT revealed 3 loci that simultaneously regulate circulating levels of fibrinogen and risk of HT: rs56026866 (PLXND1), P = 8.80 × 10-10; rs1421067 (CHD9), P = 1.81 × 10-14; and rs34780449, near ROBO1 gene, P = 1.64 × 10-8. Multitrait analysis between VWF-HT showed a novel common association regulating VWF and risk of HT after r-tPA at rs10942300 (ZNF366), P = 1.81 × 10-14. Mendelian randomization analysis did not find significant causal associations, although a nominal association was observed for FXI-HT (inverse-variance weighted estimate [SE], 0.07 [-0.29 to 0.00]; odds ratio, 0.87; 95% CI, 0.75-1.00; raw P = .05). CONCLUSION We identified 4 shared loci between hemostatic factors and HT after r-tPA treatment, suggesting common regulatory mechanisms between fibrinogen and VWF levels and HT. Further research to determine a possible mediating effect of fibrinogen on HT risk is needed.

Abstract
Hypertension is a common chronic disease in elderly people over 80 years old. Clinically, H-type hypertension occurs when hypertension coexists with hyperhomocysteinemia level of ≥ 10 umol/L. Effective identification of risk factors for H-type hypertension in the elderly can greatly improve patient prognosis.Consecutively, 494 patients with hypertension admitted to the Fourth Affiliated Hospital of Harbin Medical University from January 2019 to December 2021 were selected as the study population. They were divided into H-type hypertension (n = 197) and non-H-type hypertension groups (n = 297). Patient data were collected, including basic information, history, and clinical data. The random forest model and LASSO analysis were used to screen the influencing factors for H-type hypertension. Multiple stepwise regression analysis was used to analyze the selected variables.A total of 197 elderly people over 80 years old suffered from H-type hypertension, with an incidence rate of 39.88%. The random forest model and LASSO analysis results showed that the top 8 independent variables in importance ranking were ejection fraction (EF), fibrinogen, glycated hemoglobin (HbA1c), B-type natriuretic peptide, creatinine, fasting blood glucose, uric acid, and serum triiodothyronine levels. The results of multivariate analysis showed that EF was the protective factor, while fibrinogen, HbA1c, and creatinine were the risk factors for H-type hypertension in elderly people over 80 years old (P < 0.05).Healthcare professionals can indirectly assess the prevalence of H-type hypertension by focusing on EF, fibrinogen, creatinine, and HbA1c in elderly hypertensive patients. This provided proactive intervention and medical services to improve prognosis outcomes.

Abstract
RBC aggregation and deformability characteristics are altered by inflammatory, microcirculatory, and hemorheologic disease. These changes can be indirectly evaluated using the erythrocyte sedimentation rate (ESR). Newer point-of-care devices employ syllectometry to evaluate RBC rheology, which can give information beyond the ESR. We evaluated 2 point-of-care rheometers (iSED and MIZAR; Alcor Scientific) in 52 dogs presented to a university teaching hospital. Whole blood samples were analyzed for correlation between the ESR using the Westergren (ESRw) method (measured at 1 h and 24 h) and the predicted ESR using iSED. Plasma fibrinogen and cell-free DNA concentrations were also measured as probable markers of inflammation. The iSED-predicted ESR was positively correlated to the ESRw method at 1 h (r = 0.74; p < 0.001) and 24 h (r = 0.62; p < 0.001). Comparing dogs with or without inflammation (defined as plasma fibrinogen concentration >3.5 g/L [350 mg/dL]), significant differences were seen in the MIZAR parameters of base point, amplitude, integral, and half-time. Median cell-free DNA concentrations were higher in the group of dogs with inflammation (117 [range: 51-266] ng/mL vs. 82.7 [range: 19-206] ng/mL; p = 0.024). The iSED-predicted ESR is a good predictor of the ESRw and was obtained more rapidly. Rheometric parameters measured by MIZAR may be useful in detecting inflammation and monitoring secondary morphologic and functional changes in canine RBCs.

Abstract
INTRODUCTION Markers of hemostasis such as procoagulant factors and peak thrombin generation are associated with cardiovascular outcomes, but their associations with dementia risk are unclear. We aimed to evaluate prospective associations of selected procoagulant factors and peak thrombin generation with dementia risk. METHODS We measured levels of 7 hemostatic factors (fibrinogen, factor VII coagulant activity [FVIIc], activated factor VII [FVIIa], factor VIIa-antithrombin [FVIIa-AT], factor XI antigen [FXI], peak thrombin generation, and platelet count) among participants in the Cardiovascular Health Study, a cohort of older adults free of dementia in 1992/1993 (n = 3185). Dementia was adjudicated and classified by DSM-IV criteria through 1998/1999. Cox proportional hazards models estimated hazard ratios (HRs) for any dementia associated with 1-standard deviation (SD) differences, adjusting for sociodemographic and clinical factors and APOE genotype. Secondary analyses separately evaluated the risk of vascular dementia, Alzheimer's disease, and mixed dementia. RESULTS At baseline, participants had a median age of 73 years. Over 5.4 years of follow-up, we identified 448 dementia cases. There was no evidence of linear associations between levels of these hemostatic factors with any dementia risk (HRs per 1-SD difference ranged from 1.0 to 1.1; 95 % confidence intervals included 1.0). Results of secondary analyses by dementia subtype were similar. CONCLUSIONS In this prospective study, there was no strong evidence of linear associations between levels of fibrinogen, FVIIc, FVIIa, FVIIa-AT, FXI, peak thrombin generation, or platelet count with dementia risk. Despite their associations with cardiovascular disease, higher levels of these biomarkers measured among older adults may not reflect dementia risk.

Abstract
BACKGROUND Previous studies have shown that systemic inflammation and suboptimal nutritional status are associated with poor cancer prognosis. This study aims to investigate the prognostic value of preoperative Glasgow prognostic score (GPS) and fibrinogen-to-prealbumin ratio (FPR) in patients with CRC (colorectal cancer) after laparoscopic surgery. MATERIAL AND METHODS In this study, the clinical data of 112 patients with CRC who underwent laparoscopic surgery were retrospectively analyzed, and the 3-year and 5-year survival rates of these patients were evaluated. In addition, the prognostic role of preoperative FPR and GPS in CRC patients was assessed using X-tile software, Kaplan-Meier analysis, and Cox regression analysis. Receiver operating characteristic (ROC) curves were generated to assess the predictive value of FPR, GPS, and FPR-GPS for the survival of these patients. RESULTS The results revealed a significant negative correlation between high FPR, elevated GPS, and overall survival (OS) in patients with CRC. Univariate and multivariate Cox regression analyses identified GPS (HR=3.207, 95% CI: 1.746~6.126), FPR (HR=2.669, 95% CI: 1.052~6.772), and lymph node metastasis (HR=2.222, 95% CI: 1.199~4.115) as independent prognostic indicators for overall survival. The ROC analysis demonstrated that the prediction based on FPR and GPS outperformed a single indicator in accurately predicting the prognosis of CRC patients. CONCLUSIONS Combining the preoperative FPR with the GPS contributes to accurate prognosis assessment for CRC patients after laparoscopic surgery. Patients exhibiting high FPR and GPS values are associated with a worse prognosis.

Abstract
Ascorbic acid (AA) may contribute to restoring hemostatic balance after mental stress (MS) in overweight/obese adults. We aimed to determine the effects of AA administration on hemostatic responses to MS in overweight/obese men. Fourteen overweight/obesity men (27 ± 7 years; BMI: 29.7 ± 2.6 kg m-2) performed the Stroop color-word stress task for 5 min after non-simultaneous infusion of placebo (PL, 0.9% NaCl) and AA (3 g). Blood was collected at baseline, during MS, and 60 min after MS to measure: activated partial thromboplastin time, prothrombin time, and fibrinogen concentration, by coagulometer; platelet-derived microvesicles (PMV, mv/μL), by flow cytometry; nitrite (μM), by chemiluminescence. In PL session, MS led to decreases in PTs (stress, p = 0.03; 60 min, p < 0.001), PT-INR (stress, p < 0.001; 60 min, p < 0.01), aPTTs (60 min, p = 0.03), aPTT ratio (60 min, p = 0.04) and fibrinogen (60 min, p = 0.04), while increased PT activity (60 min, p = 0.01) when compared to baseline. Furthermore, AA increased PTs (60 min, p < 0.001), PT-INR (60 min, p = 0.03) and decreased PT activity (60 min, p < 0.001) and fibrinogen (stress, p = 0.04) when compared to PL. Nitrite was increased in response to stress during AA session (p < 0.001 vs PL). There was no difference in PMV. Ascorbic acid prevented the impaired hemostatic profile and improved nitrite response to stress in the overweight and obese adults.

Abstract
The prognostic value of preoperative white blood cell to hemoglobin ratio (WHR) and fibrinogen to albumin ratio (FAR) in colorectal cancer (CRC) is unknown. The purpose of this study was to analyze the correlation between preoperative WHR and FAR and the prognosis of CRC patients. The retrospective study analyzed the medical records of 207 patients with colorectal cancer who were admitted to Linyi People's Hospital between June 1, 2017 and June 1, 2021. The receiver operator curve was used to determine the cutoff value of 4.604 for WHR and 0.086 for FAR, and the patients were divided into high and low groups for comparative analysis of clinical data. Cox proportional hazards regression models were used to assess independent risk factors for disease-free survival (DFS) and overall survival (OS) in univariate and multifactorial analyses. Kaplan-Meier methods were used for survival analysis and logrank tests were used to assess survival differences. Multifactorial Cox analysis showed that tumor pathological stage (HR = 6.224, 95% CI:3.063-12.647, P < .001), and WHR (HR = 3.681, 95% CI:1.768-7.401, P < .001) were the independent risk factors for DFS in CRC patients. Tumor pathological stage (HR = 4.080, 95% CI:1.992-8.360, P < .001), and WHR (HR = 3.397, 95% CI:1.662-6.940, P = .001) were independent risk factors for OS. High levels of WHR and high levels of FAR were associated with lower DFS (P < .001) and OS (P < .001).CRC patients with both higher WHR and FAR had significantly lower DFS (P < .001) and OS (P < .001). DFS and OS may be shorter in CRC patients with high WHR and high FAR, perhaps associated with poor prognosis in CRC patients, and WHR and FAR may be potential CRC prognostic markers.

METHODOLOGY Between May 2010 and February 2014, 805 patients with a first myocardial infarction and 805 controls, matched for sex, age, and postal code area, were recruited to the multicentre case-control study PAROKRANK (periodontitis and its relation to coronary artery disease). All participants underwent a physical and oral examination, as well as blood sampling. Using panoramic radiography, root filled teeth, primary apical periodontitis, and secondary apical periodontitis were assessed by three independent observers. Blood samples were analysed with enzyme-linked immunosorbent assay method for the following inflammatory markers: interleukin-1β (IL-1β), IL-2, IL-6, IL-8, IL-12p70, tumour necrosis factor-α, and high-sensitivity C-reactive protein (hsCRP). Additionally, white blood cell count and plasma-fibrinogen were analysed. Associations between endodontic variables and the levels of inflammatory markers were statistically analysed with Mann-Whitney U-test and Spearman correlation, adjusted for confounding effects of baseline factors (sex, age, myocardial infarction, current smoking, diabetes, family history of cardiovascular disease, education, marital status, and periodontal disease). RESULTS Mean age of the cohort was 62 years, and 81% were males. Root fillings were present in 8.4% of the 39 978 examined teeth and were associated with higher levels of hsCRP, fibrinogen, and leukocyte count, but lower levels of IL-2 and IL-12p70. After adjusting for confounders, root filled teeth remained associated with higher levels of fibrinogen, but lower levels of IL-1β, IL-2, IL-6, and IL-12p70. Primary apical periodontitis was found in 1.2% of non-root filled teeth and associated with higher levels of IL-8 (correlation 0.06, p = .025). Secondary apical periodontitis was found in 29.6% of root filled teeth but did not relate to the levels of any of the inflammatory markers. CONCLUSIONS This study supports the notion that inflammation at the periapex is more than a local process and that systemic influences cannot be disregarded. Whether the observed alterations in plasma levels of inflammatory markers have any dismal effects on systemic health is presently unknown but, considering the present results, in demand of further investigation.

Abstract
BACKGROUND Viscoelastic testing has been used in adult hematologic malignancies in conjunction with conventional coagulation tests (CCTs) to predict coagulopathies and tailor blood product replacement. However, there is a paucity of similar pediatric studies. OBJECTIVES Analyze and correlate leukemia-associated coagulopathy in newly diagnosed pediatric leukemia patients using CCT's and Rotational Thromboelastometry (ROTEM). METHODS Pediatric patients with newly diagnosed acute leukemia underwent testing with ROTEM and CCTs on days 0, 15 and 29 of induction chemotherapy. RESULTS Sixty-two patients were enrolled. At presentation, 54.8 % of patients had platelets <50 K/μL, 73 % had prolonged PT, 1.6 % had fibrinogen <150 mg/dL. Fifteen patients (24.2 %) had WHO grade 1 bleeding and two patients (3 %) had WHO grade 4 bleeding. EXTEM/INTEM values at presentation (day 0) reflected hypocoagulability, however FIBTEM revealed hypercoagulability. Patients showed a progressive hypocoagulability in all ROTEM assays by day 15 (day 0 vs day 15, p < 0.001), with improvement by day 29 (day 15 vs day 29, p < 0.001). Day 0 ROTEM parameters were comparable to day 29. Fibrinogen strongly correlated with ROTEM at all three time points (p < 0.0001), along with platelet count with moderate correlations (p < 0.001). CONCLUSION Fibrinogen and platelets appear to be the drivers of leukemia associated coagulopathy in the pediatric population, suggesting the utility of using CCTs and ROTEM in this population to better evaluate hemostatic function and guide blood product replacement.

Abstract
BACKGROUND/AIM Pretreatment fibrinogen levels are a promising prognostic marker for some malignancies. The aim of the present study was to evaluate the clinical impact of fibrinogen levels before treatment in patients with esophageal cancer who underwent curative resection. PATIENTS AND METHODS This study included 123 patients who underwent curative treatment for esophageal cancer between 2005 and 2020. The prognosis and clinicopathological parameters in the high fibrinogen and low fibrinogen groups were analyzed. RESULTS Overall survival (OS) stratified by individual clinical factors was compared using the log-rank test, and a significant difference was observed when a pretreatment fibrinogen level of 400 g/dl was used as a cutoff value. The comparison of the patient background factors between the high fibrinogen (400 g/dl) and low fibrinogen (<400 g/dl) groups revealed significant differences in pathological T status and lymph node metastasis. In the low fibrinogen group, the OS rates at 3 and 5 years after surgery (71.4% and 58.1%, respectively) were significantly higher than those in the high fibrinogen group (38.3% and 32.4%, respectively). Univariate and multivariate analyses for OS showed that the fibrinogen level prior to treatment was a significant prognostic factor. Similar results were observed for recurrence-free survival. In addition, when the first recurrence site was compared, there were marginally significant differences in hematologic recurrence. CONCLUSION Pretreatment fibrinogen levels are a significant risk factor in patients with esophageal cancer. Therefore, pretreatment fibrinogen levels are a promising prognostic factor for patients with esophageal cancer.

Abstract
BACKGROUND Pigmented purpuric dermatosis (PPD) is characterized by grouped petechiae, purpuric macules, and pigmentation in the bilateral lower extremities. It runs a chronic and relapsing course. Pathophysiology is poorly understood, but it has been proposed to be an immune-complex disease or capillaritis. This study aimed to determine the incidence and patterns of positive direct immunofluorescence (DIF) findings in patients with clinically and histopathologically confirmed PPD. The association between DIF deposition type and clinical profile was also analyzed. METHODS Patients with a clinical and histopathologic PPD diagnosis who had undergone DIF studies at a tertiary medical center with attached dermatopathology and immunofluorescence diagnostic centers between January 2002 and December 2021 were included in this study. Data on age, sex, disease duration, comorbidities, and drug intake were collected from medical records. RESULTS There were 65 patients who satisfied the inclusion criteria. Among them, 58 (89%) had at least one positive finding and 53 (82%) were vascular deposition of immunoglobulin (Ig), complement, or fibrinogen. The most common vascular deposition was fibrinogen (71%) followed by C3 (62%), IgM (18%), IgA (6%), and IgG (3%). Fibrinogen deposition was associated with hypertension (p < 0.03). There was no association between vascular DIF deposition of IgG, IgA, and C3, with age, sex, comorbidities, disease duration, and drug history. CONCLUSION The most common DIF findings in PPD were vascular deposition of fibrinogen and C3, with or without Ig presence. DIF findings supported a vascular origin in PPD but not an immune complex-mediated disease. Hypertension was associated with fibrinogen deposition and may play a role in its pathophysiology.

Abstract
BACKGROUND Fibrinogen to pre-albumin ratio (FPR) is a promising predictor of mortality in various cancers. The aim of this study was to explore the prognostic value of FPR to predict mortality in peritoneal dialysis (PD) patients. METHODS We retrospectively analyzed 324 incident PD patients form January 2011 to December 2020. Patients were stratified based on the optimal thresholds for FPR at baseline to predict overall and cardiovascular mortality during follow-up. The association of FPR and all-cause and cardiovascular mortality was evaluated by Kaplan-Meier curve and Cox regression analysis. RESULTS All patients were divided into three groups based on the optimal cutoff value of FPR. Higher FPR levels were strongly correlated with worse overall and cardiovascular mortality in PD patients. Compared with patients in the lowest FPR tertile (<14.3), those in the highest terile (≥18.8) had multivariable-adjusted hazard ratios (95% CI confidence interval) of 3.37 (1.76-6.49) and 2.86 (1.31-6.23) for all-cause and cardiovascular mortality, respectively. Significant differences in overall survival were observed across nearly all subgroups after stratification. CONCLUSIONS Patients with a high FPR had increased all-cause and cardiovascular mortality. FPR is a potential prognostic indicator in PD patients.

Abstract
Most coagulation tests are photo-optical turbidimetric assays that require the removal of cellular components from whole blood for optical clearing. If the resulting blood plasma samples are hemolyzed, they may become unsuitable for turbidimetric analysis. To resolve this issue, whole-blood analogs to plasma turbidimetric assays need to be developed. Using samples collected from non-smokers (normal group), smokers (thrombotic group), and hemophilia A (bleeding group) patients, we demonstrate that the reaction time assessed from whole blood viscosity data of the drop-of-blood acoustic tweezing spectroscopy (ATS) technique strongly correlates (Rp ≥ 0.95) with PT/aPTT values obtained from plasma turbidimetric data. Linear correlation (Rp ≥ 0.88) was also obtained between the viscous and elastic outputs of the ATS technique and the fibrinogen concentration. The integration of ATS data enabled the assessment of the functional level of fibrin cross-linkers such as factor XIII. Overall, ATS allows comprehensive sample-sparing analysis of whole blood coagulation for reliable and safe diagnosis of bleeding/thrombosis risks.

Abstract
Background The study aims to explore diagnostic value of albumin/fibrinogen ratio (AFR) and C-reactive protein (CRP)/albumin (ALB)/globulin (GLO) ratio (CAGR) for periprosthetic joint infection (PJI). Methods A retrospective analysis was conducted on clinical data collected from 190 patients who had joint replacement surgery in Qilu Hospital of Shandong University (Qingdao), from January 2017 to December 2022. Based on the occurrence of PJI after surgery, patients were divided as an infection group (10 cases) and non-infection group (180 cases). Diagnostic indicators were analyzed, univariate and multivariate logistic regression analyses were further performed to identify factors related to PJI. Sensitivity and specificity of AFR and CAGR, both individually and in combination, were calculated using ROC curves, and their diagnostic performance was compared based on the area under the curve (AUC). Results Levels of CRP, ESR, FIB, GLO, and CAGR were significantly higher in the infection group than in non-infection group (P < 0.05). Levels of ALB and AFR were significantly lower in infection group (P < 0.05). Multivariate logistic regression analysis reviewed that CRP (OR = 3.324), ESR (OR = 2.118), FIB (OR = 3.142), ALB (OR = 0.449), GLO (OR = 1.985), AFR (OR = 0.587), and CAGR (OR = 2.469) were factors influencing PJI (P < 0.05). The AUC for AFR and CAGR in diagnosing PJI were 0.739 and 0.780, while AUC for their combined detection was 0.858. Conclusion Abnormal levels of AFR and CAGR are associated with PJI, and their combined use has certain diagnostic value for PJI.

Abstract
BACKGROUND At present, much evidence shows that many cancers have a high risk of thrombosis. Several studies have shown the prognostic value of platelet-related parameters and coagulation indexes in prostate cancer (PCa). However, the association between platelet-related parameters, coagulation indexes and bone metastasis of Pca is unclear. METHODS A total of 234 pathologically diagnosed patients with Pca were consecutively collected and stratified into the bone metastasis group and non-bone metastasis group according to the results of the bone scan. ROC curve analysis was used to explore the auxiliary predictive value of single and combined parameters for bone metastasis in Pca patients. Univariate and multivariate Logistic regression analyses were used to determine the relationship between platelet-related parameters, coagulation indexes, and bone metastasis of Pca. RESULTS Platelet count (PLT), fibrinogen (Fib), prostate-specific antigen (PSA), and D-dimer (DD) levels of the bone metastasis group were significantly higher than the non-bone metastasis group (P = 0.010, P < 0.001, P < 0.001, and P < 0.001, respectively). This study confirmed that PLT, PSA, DD and Fib have auxiliary predictive value for prostate cancer bone metastasis. After the combination of PLT, PSA, DD and Fib, the area under the curve, sensitivity and specificity increased significantly. The univariate logistic analysis demonstrated that PLT (OR: 1.008, P = 0.011), DD (OR: 2.690, P < 0.001), PSA (OR: 1.073, P < 0.001), Gleason score (OR: 7.060, P < 0.001), and Fib (OR: 2.082, P < 0.001) were significantly positively correlated with bone metastasis of Pca. Multivariate analysis showed that PSA (OR: 1.075, P < 0.001), DD (OR: 2.152, P < 0.001), Gleason score (OR: 2.904, P < 0.001), and Fib (OR: 1.706, P < 0.001) were independent risk factors for bone metastasis of Pca after adjusting for Age, BMI and other confounding factors. CONCLUSIONS Higher platelet, D-dimer, prostate-specific antigen, Gleason score, and fibrinogen levels may predict a worse prognosis in patients with Pca. PLT, DD, and Fib, as readily available and relatively inexpensive indicators, help predict bone metastasis of Pca. It is suggested that PLT, DD and Fib may be helpful in the risk stratification of Pca.

Abstract
Objective: To investigate whether hypersensitive C-reactive protein (Hs-CRP), homocysteine, fibrinogen, and omentin-1 could predict gestational diabetes mellitus (GDM) risk. Methods: Case-control study was conducted at Hengshui People's Hospital. The GDM group included data about 150 patients aged between 22 and 35 years in 24-28 weeks. An equivalent comparative control group without GDM was composed of the same pool of patients. Body mass index (BMI), total cholesterol (TC), triglyceride, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), oral glucose tolerance test (OGTT) 0-2h, hs-CRP, homocysteine, fibrinogen, and omentin-1 levels were studied in the serum samples of research groups. Univariate logistic regression analysis was used to explore the risk factors of GDM. The area under the curve (AUC) was calculated by the receiver operating characteristic curve (ROC) to analyze the predictive values. Results: Hs-CRP, homocysteine, and fibrinogen in GDM group were significantly higher than those in non-GDM group. Omentin-1 were significantly lower than those in non-GDM group. Logistic regression showed that hs-CRP, homocysteine, fibrinogen, and omentin-1 were risk factors for GDM. The AUC of the established GDM risk prediction model was 0.977, and the sensitivity and specificity were 92.10% and 98.70%, respectively; which were greater than that of hs-CRP, homocysteine, fibrinogen, and omentin-1 alone. Conclusions: Hs-CRP, homocysteine, fibrinogen, and omentin-1 in pregnancy have important clinical value for the prediction of GDM. We used these laboratory indications to establish a GDM risk prediction model that allows for early detection and treatment of GDM, lowering the morbidity of maternal and infant complications.

Abstract
Limited studies have investigated the differences between the levels of plasma coagulants and tumor markers in ovarian cancer. Therefore, we conducted this study to determine and compare the level of coagulation, fibrinolysis and tumor markers in patients with benign and malignant ovarian tumors. This cross-sectional study was conducted between January 2022 and February 2023 in Imam Hossein Hospital on patients with ovarian mass. Laboratory tests included platelet count, PT, INR, PTT, fibrinogen and D-dimer were sent to the pathology laboratory to be examined by a pathologist. Based on histopathology, patients were divided into benign, borderline and malignant groups. Logistic regression was used for determine predictors of malignancy. Receiver operating characteristics (ROC) curves and their corresponding 95% CI were determined for the predictor value of the full model. From 141 investigated patients, tumor type in 124 (87.94%) patients were benign, in 12 (8.51%) was malignant and in 5 (3.55%) was borderline. D-dimer, Ca-125 and HE4 were significantly higher in the patients with malignant tumor type (P<0.001), whereas AFP was significantly higher in patients with borderline tumor type (P<0.001). With one-unit increase in D-dimer odds of borderline/malignant tumor 0.3% increases (OR=1.003, 95% CI: 1.001, 1.006) and with one-unit increase in Ca-125 odds of borderline/malignant tumor 1% increases (OR=1.01, 95% CI: 1.003, 1.02). We found that plasma fibrinogen, D-dimer and Ca-125 levels are independently associated with malignant ovarian tumors and combined use of these markers has the high discriminant power for distinction of benign and malignant ovarian masses. .

Abstract
OBJECTIVE We aimed to investigate the relationship between gestational diabetes mellitus (GDM) and maternal serum hepassocin concentrations. MATERIALS AND METHODS This cross-sectional study was conducted with 88 pregnant women who applied to the Ümraniye Training and Research Hospital Gynecology and Obstetrics Clinic between April 2022 and November 2022. The GDM group consisted of 44 pregnant women who had a 75-g OGTT between the 24th and 28th week of pregnancy and were diagnosed with GDM. The control group consisted of 44 healthy pregnant women who were matched with the GDM group in terms of age and body mass index (BMI) and had a normal 75-g OGTT result. Demographic characteristics, laboratory findings, and perinatal outcomes were noted. Two groups were compared in terms of maternal serum hepassocin concentrations. RESULTS Both groups were similar in terms of age, BMI, weight gain, gravida, parity, polycystic ovary syndrome history, history of diabetes mellitus in the family, and the gestational week at blood sampling for hepassocin (p>0.05 for each). The median maternal serum hepassocin concentration was found to be 18.21 ng/ml in the GDM group, while it was determined as 13.05 ng/ml in the non-GDM group (p=0.012). The GDM group was divided into two groups: the group that only dieted until birth and the group that used insulin until birth for blood glucose regulation. The median hepassocin concentration was found to be 17.99 ng/ml in the diet-only GDM group and 32.15 ng/ml in the insulin-using GDM group. ROC analysis was performed to determine the value of maternal serum hepassocin concentration in predicting GDM. AUC analysis of maternal serum hepassocin for estimation of GDM was 0.656 (p=0.012, 95% CI=0.53-0.77). The optimal threshold value for maternal serum hepassocin concentration was determined as 14.13 ng/ml with 61.4% sensitivity and 61.4% specificity. CONCLUSION Serum hepassocin concentration evaluated between 24 and 28 weeks of gestation was found to be higher in pregnant women with GDM than in the non-GDM group. The highest serum hepassocin concentration was found in the GDM group using insulin for blood glucose regulation. Hepassocin seems to be a promising molecule that can be used in GDM screening in pregnant women who do not want to have an OGTT in the future.

Abstract
There is mounting evidence that malnutrition and systemic inflammation status are involved in the prognosis of various cancers. In this study, we aimed to evaluate the prognostic value of the pretreatment fibrinogen-albumin ratio index (FARI) in nasopharyngeal carcinoma (NPC) patients receiving definite radiotherapy. NPC patients who received definite radiotherapy between January 2013 and December 2019 were included. A receiver operating characteristic (ROC) curve was used to determine the optimal cutoff value. The clinicopathological characteristics of the patients were compared via the Chi-square test. Survival curves were analyzed by the Kaplan‒Meier method. The prognostic factors were evaluated by univariate and multivariate analyses via Cox hazards regression analysis. A total of 225 patients were enrolled, and the median follow-up time was 48.5 months. High FARI was correlated with worse ECOG score (p = 0.003), higher EBV-DNA titer (p = 0.047), and more advanced clinical stage (p < 0.001). In the multivariable analysis, FARI independently predicted OS (HR 2.399, 95% CI 1.294-4.450, P < 0.001), PFS (HR 2.085, 95% CI 1.200-3.625, P = 0.009), and DMFS (HR 2.527, 95% CI 1.288-4.958, P < 0.001). The current findings suggest that a high pretreatment FARI is an independent predictor of OS, PFS and DMFS in NPC patients undergoing definite radiotherapy.

Abstract
BACKGROUND Albumin to fibrinogen ratio (AFR), a new inflammatory marker, has emerged as a useful indicator to predict adverse outcomes for several diseases. However, whether AFR could be a new useful indicator to predict mortality in HCM patients remains to be evaluated. The study explored the predictive value of AFR for HCM-related death in adult HCM patients. METHODS A total of 404 HCM patients were eventually enrolled in the study according to the inclusion criteria. Patients were divided into two groups based on the median of baseline AFR. The association between AFR and HCM-related death was analyzed. RESULTS During a median follow-up of 4.75 years, HCM-related death was observed in 45 patients (11.1%). The incidence of HCM-related death was significantly higher in the low AFR group (log-rank p < 0.001). With the high AFR group as reference, the unadjusted hazard ratio (HR) for HCM-related death was 2.97 (95% confidence interval [CI]: 1.53-5.75, p = 0.001) in the low AFR group, and after adjusting for potentially confounding variables, the adjusted HR for low AFR group was 3.15 (95% CI: 1.56-6.37, p = 0.001). No significant interactions between AFR and other variables were observed in subgroup analysis. Sensitivity analyses in patients with normal albumin and fibrinogen showed similar results. CONCLUSION AFR is an independent prognostic factor for HCM-related death, adult HCM patients with a lower AFR have a higher risk of HCM-related death.

Abstract
Low-grade chronic inflammation linked to obesity can lead to alterations in biomarkers of iron status. The aim of this study was to investigate the primary determinant of serum iron levels among anthropometric measurements, body fat, and serum biomarkers of low-grade chronic inflammation in a group of adult individuals with severe obesity. We enrolled 114 individuals (84 females; 30 males) aged 40.96 ± 12.54 years. Weight and body mass index (BMI) were 121.20 ± 22.33 kg and 44.94 ± 7.29 kg/m2, respectively. Some 30% of individuals had class-II obesity (BMI ≥ 35 ≤ 39.9 kg/m2) and 70% had class-III obesity (BMI ≥ 40 kg/m2). A weak, albeit significant, inverse correlation was found between serum iron levels and c-reactive protein (CRP) (r = -0.259, p = 0.008), fibrinogen (r = -0.261, p = 0.006), BMI (r = -0.186, p = 0.04), waist circumference (WC) (r = -0.265, p = 0.004), and fat mass % (r = -0.285, p = 0.003). With multiple linear regression analysis including CRP, fibrinogen, BMI, WC, and fat mass % as independent variables and serum iron levels as dependent variable, WC was entered in the first step (p = 0.001), which was followed by fat mass % (p = 0.047) and CRP (p = 0.047). Grouping the individuals according to the interquartile range of BMI, WC, and fat mass % (Q1-Q4), the lowest serum iron levels were found in Q4 groups of WC and fat mass % (p = 0.02), while no significant differences were found between groups in BMI quartiles. In conclusion, in our study, population serum iron levels were inversely associated with BMI, visceral obesity, fat mass %, CRP, and fibrinogen, but WC was the major negative predictor of serum iron level. These results supported the fact that visceral distribution of body fat, more than obesity per se, was associated with low serum iron levels in adult individuals with severe obesity.

Abstract
BACKGROUND Thomboelastography (TEG) is a point of care viscoelastic test that provides an assessment of clot formation and kinetics. Antiplatelet agents are commonly used but there is limited literature evaluating their possible effects on overall clot kinetics. We aimed to evaluate the relationship between antiplatelet agents and clot kinetics as defined by TEG. METHODS This is a retrospective study of adult patients who underwent TEG from February 2018 to July 2020. Patients who received anticoagulants or blood transfusions within 72 hours, had an incomplete TEG, were diagnosed with COVID-19, or had liver failure were excluded. Patients were stratified based on antiplatelet status. RESULTS Of 1060 patients, 119 were included (50 controls, 69 antiplatelet agents-37 aspirin monotherapy, 26 dual antiplatelet therapy). Between the control and antiplatelet therapy groups, there was no significant difference in clot time, maximal clot strength, or fibrinogen level. When compared to control patients, patients on dual antiplatelets had significantly higher fibrinogen levels (408.1 mg/dL vs 481.5 mg/dL, P = .013) but no significant differences in clot time or maximal clot strength. In our subgroup analysis, patients on dual antiplatelets had increased maximal clot strength (58.8° vs 63°, P = .005) and fibrinogen levels (384.1 mg/dL vs 481.5 mg/dL, P = .005) compared to those on aspirin alone. DISCUSSION Compared to control patients and those on aspirin alone, patients on dual antiplatelets have increased maximal clot strength and increased fibrinogen levels. These results can help physicians better target product resuscitation in patients who are on antiplatelet agents.

Abstract
Nutritional markers for adverse clinical outcomes following total joint arthroplasty (TJA) remain controversial. This study attempted to explore the validity of the albumin-to-fibrinogen ratio (AFR) in nutritional assessment and assess its predictive value for adverse postoperative outcomes in patients receiving TJA. 2137 patients who underwent primary TJA between January 2016 and June 2021 were screened. We performed receiver operating characteristic curves and area under the curve (AUC) to assess predictive value and establish optimal thresholds. Multivariate regression models were then used to assess potential associations between AFR and adverse postoperative outcomes. AFR might predict postoperative deep surgical site infections (AUC = 0.699, P = .023). The optimal threshold for wound complications, determined by the Youden index, was 12.96. Compared with patients with reduced AFR, patients with high AFR exhibited an enhanced risk of adverse postoperative outcomes (adjusted OR: 4.010-8.832, all P < .05). Using multivariate Cox regression analysis, we further confirmed a higher risk of adverse postoperative outcomes in patients with low AFR (adjusted HR: 3.733-7.335, all P < .05). Reduced preoperative AFR markedly enhanced adverse postoperative outcomes. Hence, AFR may serve as a potential biomarker for nutritional assessment, and may predict postoperative wound complications following primary TJA.

Abstract
BACKGROUND Correct TIMI frame count (CTFC), myocardial blush grade (MBG), and ST-segment resolution (STR) are parameters used to evaluate reperfusion at the microvascular level in patients that have undergone primary percutaneous coronary intervention (pPCI). Fibrinogen-to-albumin ratio (FAR) has been associated with thrombotic events in patients with ST-elevation myocardial infarction (STEMI) and chronic venous insufficiency. OBJECTIVES To investigate the relationship of FAR with CTFC, MBG, and STR. Methods: The study included 167 consecutive patients who underwent successful pPCI for STEMI and achieved TIMI-3 flow. The cases were divided into two groups, high (>0.0765) and low FAR (≤0.0765), according to the cut-off value of this parameter in the receiver operator characteristic analysis (ROC). STR, CTFC, and MBG were used to evaluate myocardial reperfusion. P values<0.05 were considered statistically significant. RESULTS CTFC value, SYNTAX score, neutrophil/lymphocyte ratio, low-density lipoprotein, glucose, and peak cTnT were significantly higher, whereas STR, MBG, and LVEF were lower in the high FAR group. Spearman's correlation analysis revealed a significant relationship between the FAR and STR (r=-0.666, p<0.001), MBG (-0.523, p<0.001), and CTFC (r=0.731, p≤0.001). According to the logistic regression analysis, FAR, glucose, peak cTnT, and pain to balloon time were the most important independent predictors of MBG 0/1, CTFC>28, and STR<50%).ROC analysis revealed that the cut-off value of FAR≥0.0765 was a predictor of incomplete STR with a sensitivity of 71.9 % and a specificity of 69.8 %, MBG0/1 with a sensitivity of 72.6 % and a specificity of 68.6 %, and CTFC >28 with a sensitivity of 76 % and a specificity of 65.8 %. CONCLUSIONS FAR is an important independent predictor of microvascular perfusion in patients undergoing pPCI for STEMI.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a significant global health burden, with postoperative hospital length of stay (LOS) impacting patient outcomes and healthcare costs. Existing nutritional, inflammatory, and coagulation indices can predict LOS, with particular interest in albumin, fibrinogen, and D-dimer. This study investigates the predictive value of preoperative albumin-to-fibrinogen ratio (AFR) and albumin-to-D-dimer ratio (ADR) for postoperative LOS in HCC patients. METHODS This retrospective study involved 462 adult HCC patients who underwent partial hepatic lesion excision between February 2016 and August 2022. We analyzed demographic and clinical data, including preoperative blood samples, surgical approach, and LOS. The primary outcome measure was LOS, calculated from the date of surgery to the date of hospital discharge. Preoperative AFR and ADR were calculated. The ROC curves determined optimal cutoff points. The Cox proportional hazards model, Kaplan-Meier method, and the log-rank test were used for statistical analysis. RESULTS The study established an optimal AFR cutoff value of 15.474, with a higher AUC value than ADR, indicating superior predictive potential for postoperative LOS. Participants with high-AFR (AFR > 15.474) had a shorter median LOS (13 vs. 15 days, p < 0.001) compared to those with low-AFR (AFR ≤15.474). Multivariate analysis revealed high-AFR (HR: 1.99; p < 0.001) as a positive influence on LOS reduction, whereas Child-Pugh rated as B (HR: 0.49; p < 0.001), laparotomy (HR: 0.37; p < 0.001) and total bilirubin >20.5 μmol/L (HR: 0.58; p < 0.001) negatively impacted LOS reduction. Subgroup analysis confirmed AFR's predictive ability for patients experiencing reduced or prolonged LOS due to Child-Pugh score, surgical methods, and total bilirubin concentrations. Even within normal albumin and fibrinogen levels, patients with high-AFR exhibited a shorter LOS (all p < 0.001). CONCLUSIONS Our findings underscore the value of the AFR as a reliable predictor of LOS in HCC patients. An AFR greater than 15.474 consistently correlated with a shorter LOS, suggesting its potential clinical utility in guiding perioperative management and resource allocation in HCC patients.

Abstract
BACKGROUND Previous studies have reported lipoprotein(a) was related to increased risk of ischemic stroke. However, the role of fibrinogen in their associations was not fully elucidated. AIM We aimed to investigate the mediating role of fibrinogen in the association between lipoprotein(a) and risk of ischemic stroke. METHODS A total of 516 patients with ischemic stroke were matched 1:1 to patients without ischemic stroke for age and gender. Serum lipoprotein(a) and plasma fibrinogen levels were collected on the basis of the results of biochemical tests. Multivariate conditional logistic regression analyses were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for lipoprotein(a) levels and ischemic stroke risk. Mediation analysis were further conducted to evaluate the potential mediating role of fibrinogen in the association between lipoprotein(a) and ischemic stroke risk. RESULTS The lipoprotein(a) level of subjects with ischemic stroke was significantly higher than that of subjects without ischemic stroke (P < 0.001). Each SD increment of lipoprotein(a) was associated with 27% higher odds (OR 1.27, 95%CI: 1.11, 1.45) increment in ORs of ischemic stroke. Furthermore, mediation analyses indicated that fibrinogen mediated 10.15% of the associations between lipoprotein(a) and ischemic stroke. CONCLUSIONS Higher level of lipoprotein(a) was independently associated with increased risk of ischemic stroke and fibrinogen partially mediated the associations of lipoprotein(a) and ischemic stroke risk.

Abstract
A recent ex vivo study found that post-cardiopulmonary bypass platelet defects can be restored with supplemental fibrinogen, but the clinical significance of this finding will require further study. We propose that the best management strategy for achieving haemostasis in bleeding surgical patients is to identify individualised coagulation defects and then use a targeted therapeutic approach that addresses each identified defect systematically.

Abstract
OBJECTIVE To determine whether peripheral blood parameters have any predictive value for all-frequency Sudden Sensorineural Hearing Loss (SSNHL). METHODS We chose 78 individuals with all-frequency SSNHL who had been admitted to our department. They were divided into two groups: the effective group and the ineffective group. In patients with all-frequency SSNHL, the prognostic variables, including peripheral blood tests and clinical traits, were examined by a logistic regression analysis. In addition, the predictive value was carried out. RESULTS The effective rate of all-frequency SSNHL was 61.5%. Pre-treatment hearing level and the proportion of patients with diabetes were both significantly lower in the effective group than in the ineffective group (p = 0.024 and 0.000, respectively). The levels of fibrinogen and C-reactive protein were also significantly different between the two groups (p = 0.001 and 0.025, respectively). Pre-treatment hearing level and fibrinogen level both significantly impacted the prognosis of all-frequency SSNHL (p = 0.032 and 0.002, respectively), according to a logistic regression analysis. Furthermore, the prognosis was significantly predicted by both fibrinogen level and pre-treatment hearing level (p = 0.001 and 0.0002, respectively). The receiver operating characteristic curve showed that the fibrinogen level had a sensitivity of 85.4% and a specificity of 60.0% for predicting the prognosis of all-frequency SSNHL. CONCLUSION For the prognosis of all-frequency SSNHL, the fibrinogen level can be regarded as a useful predictor. The level of C-reactive protein, however, does not have a significant prognostic effect on predicting all-frequency SSNHL. Therefore, more attention should be devoted to the level of fibrinogen in the acute period of all-frequency SSNHL. LEVEL OF EVIDENCE: 4

Abstract
OBJECTIVE Sudden sensorineural hearing loss is considered idiopathic in up to 90 per cent of cases. This study explored the role of blood tests as biomarkers for the diagnosis and prognosis of sudden sensorineural hearing loss. METHOD Two researchers filtered 34 papers into the final review. This review was pre-registered on the Prospero database and conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. RESULTS Raised inflammatory markers are almost universal in sudden sensorineural hearing loss, suggesting an inflammatory or autoimmune process. The most useful biomarkers are neutrophil-lymphocyte ratio, platelet-lymphocyte ratio and fibrinogen level. Focused investigations should be deployed on a case-by-case basis to identify underlying metabolic, infective and autoimmune conditions. CONCLUSION A full blood count and coagulation screen (fibrinogen) is recommended in all cases of sudden sensorineural hearing loss. These are inexpensive, accessible and offer as much diagnostic and prognostic information as any other biomarker. There is emerging evidence regarding specific biomarkers for sudden sensorineural hearing loss prognosis, with heat shock protein-70, anti-endothelial cell antibody and prestin demonstrating potential; investigation of their validity through prospective, controlled research is recommended.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a frequent endocrinopathy in young women with significantly increased cardiometabolic risk. Siblings of women with this disorder are at increased risk of insulin resistance and androgen excess. The current study was aimed at investigating cardiometabolic effects of atorvastatin in sisters of women with PCOS. METHODS This prospective observational study compared two age-, body mass index-, blood pressure-, and plasma lipid-matched groups of women with hypercholesterolemia: sisters of PCOS probands (group A) and unrelated control subjects (group B), receiving atorvastatin (40 mg daily). Plasma lipids, glucose homeostasis markers, concentrations of sex hormones, high-sensitivity C-reactive protein (hsCRP), homocysteine, fibrinogen and uric acid, and the urinary albumin-to-creatinine ratio (UACR) were measured before entering the study and 6 months later. RESULTS Both groups differed in the degree of insulin resistance, testosterone, free androgen index (FAI), circulating levels of hsCRP and homocysteine, and UACR. There were no between-group differences in the impact of atorvastatin on plasma lipids. Despite reducing hsCRP and homocysteine in both groups of women, the effect on these biomarkers was stronger in group B than in group A. Only in group B, atorvastatin did reduce fibrinogen, uric acid, and UACR. Only in group A, atorvastatin did worsen insulin sensitivity and tended to reduce testosterone and FAI. The impact of atorvastatin on hsCRP, homocysteine, fibrinogen, uric acid, and UACR inversely correlated with testosterone and FAI. CONCLUSION The obtained results suggest that sisters of women with PCOS may benefit to a lesser degree from atorvastatin treatment than other women.

Abstract
BACKGROUND The aim of the study was to conduct a comprehensive performance evaluation of the Mindray CX-9000 fully automated coagulation analyzer for the detection of the seven coagulation items. METHODS The performance of activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB), thrombin time (TT), D-dimer (D-D), fibrinogen degradation product (FDP), and antithrombin Ⅲ (AT) was validated for precision, linear range, carryover contamination rate, reference interval validation, inter-method agreement, and anti-interference ability. RESULTS The intra- and inter-precision (coefficient of variation, CV%) of all seven items was less than the target CV%; the carryover contamination rates for different concentrations and between items were < 10%. The slope of the linear regression equation for the theoretical and measured values of the linear range was within 1 ± 0.05 and R ≥ 0.975. The reference interval quoted from the manufacturer's reference interval passed ≥ 95%. The CX-9000 was compared with the results of the reference instrument STAGO R MAX (STA-R MAX) and the p-values for all items ranged from 0.822 to 0.987. Within the concentration range claimed by the manufacturer, the interference errors produced by all items met the manufacturer's claimed criteria, except for triglycerides which produced interference errors > 10% for the FIB, D-D, FDP, and bilirubin which produced interference errors for the FIB and D-D assays. CONCLUSIONS The CX-9000 automatic coagulation analyzer has good stability and repeatability, a wide linear range of detection, low carryover contamination rate, and high resistance to interference, making it suitable for the testing of clinical specimens.

Abstract
BACKGROUND The Clinical and Laboratory Standards Institute recommends rejecting hemolyzed samples for coagulation tests. Sysmex CS5100 analyzer using an optical method is commonly used in laboratories. The influence of hemolysis on coagulation test has rarely been studied when tested on Sysmex CS5100. Determining this influence is necessary. METHODS Freshly collected samples were artificially hemolyzed to simulate the hemolysis processes. Coagulation tests were conducted on a Sysmex CS5100 coagulation analyzer. Detection values before and after hemolysis were compared. RESULTS The results showed that after hemolysis detection, the prothrombin time (PT) statistically decreased, while the partial thromboplastin time (APTT) statistically increased. There were no significant differences in fibrinogen (Fg), thrombin time (TT), D-dimer (DD) or fibrinogen degradation products (FDPs). Antithrombin activity was elevated in hemolyzed samples. CONCLUSIONS Although differences in PT and APTT were statistically significant, there was no need for rejection of hemolyzed samples due to insufficient clinical effects when tested on Sysmex CS5100 analyzer. Falsely elevated AT result may lead to misdiagnosis in patients with severe diseases, which should be carefully considered.

Abstract
PURPOSE OF REVIEW Fibrin polymerization is essential for stable clot formation in trauma, and hypofibrinogenemia reduces hemostasis in trauma. This review considers fibrinogen biology, the changes that fibrinogen undergoes after major trauma, and current evidence for lab testing and treatment. RECENT FINDINGS Fibrinogen is a polypeptide that is converted to fibrin by the action of thrombin. During trauma, fibrinogen levels are consumed and reduce within the first few hours because of consumption, dilution, and fibrinolysis. Fibrinogen levels usually rebound within 48 hours of injury and can contribute to thrombotic events. The Clauss fibrinogen assay is the gold standard test for fibrinogen levels, although viscoelastic hemostatic assays are often used when a lab delay is anticipated. An evidence-based threshold for fibrinogen replacement is not well established in the literature, but expert opinion recommends maintaining a level above 150 mg/dl. SUMMARY Hypofibrinogenemia is an important cause of nonanatomic bleeding in trauma. Despite multiple pathologic causes, the cornerstone of treatment remains fibrinogen replacement with cryoprecipitate or fibrinogen concentrates.

Abstract
Preeclampsia (PE) is a disorder that affects approximately 5% to 10% of pregnant women. Timely and accurate identification of PE and assessment of its severity are crucial. Therefore, it is necessary to develop predictive indicators which are easily measured in routine antenatal examinations to enable the early detection of PE and assess its severity. We designed a single-center retrospective study in our daily work to assess whether the serum levels of fibrinogen to albumin ratio (FAR), fibrinogen (Fib), albumin (ALB), prothrombin time, calcium (Ca), activated partial thrombin time, creatinine (Cr), D-dimer(D-D), platelet, white blood cell, neutrophil, and lymphocyte counts could help in assessing PE and evaluating its severity. Our findings showed that the serum levels of FAR, Cr, Fib, and D-D were significantly higher in the severe preeclampsia group (sPE) compared with the control and mild preeclampsia groups, whereas the levels of ALB and Ca were significantly lower in sPE patients. In addition, no differences were found between the control and PE groups in terms of prothrombin time, activated partial thrombin time, platelet, white blood cell, neutrophils, and lymphocytes counts. Furthermore, FAR is a novel and better indicator for evaluating the severity of PE, which has not been reported before. And it is an independent risk factor for the development of sPE. In conclusion, the serum levels of FAR, Cr, D-D and Fib were positively correlated with PE, whereas ALB and Ca were negatively correlated with PE severity, which might be valuable in evaluating the severity of PE. FAR proved to be a feasible diagnostic marker for sPE with sensitivity and specificity comparable to those of ALB and Fib.

Abstract
Although molecular biology has made great progress in recent years, the detection rate of mycobacterium tuberculosis (MTB) is still not ideal. This study aimed to evaluate the role of prognostic inflammatory index (PII) and systemic inflammatory response index (SIRI) in the auxiliary diagnosis of bacteria-negative pulmonary tuberculosis (TB). Sixty patients diagnosed with bacteria-negative pulmonary TB at the Affiliated Hospital of Qinghai University between October 2019 and September 2022 were randomly selected as the case group, and seventy patients with nontuberculous pulmonary infection in the same department of the same hospital during the same period were randomly selected as the control group. Baseline data and values of erythrocyte sedimentation rate (ESR), lymphocyte count (LY), neutrophil count (NE), monocyte count (MO), albumin (ALB), prealbumin (PA), C-reactive protein (CRP), fibrinogen (FIB), neutrophil-to-lymphocyte ratio (NLR), PII, and SIRI were compared between the 2 groups. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic efficacy of PII and SIRI in the diagnosis of bacteria-negative pulmonary TB. No significant differences were found between the 2 groups in terms of sex and age (P > .05); however significant differences were observed in relation to body mass index (BMI), ESR, LY, NE, MO, ALB, PA, CRP, FIB, NLR, PII, and SIRI (P < .05). ROC curve analysis showed that area under curve (AUC) value {0.84 [95% CI (0.77, 0.90)]} and specificity {82.86% [95% CI (72.0, 90.8)]} of PII were the highest, while the sensitivity {86.67 [95% CI (75.4, 94.1)]} of NLR + PII was the highest. Pairwise comparison of the 7 indicators of ROC curve was performed, and only the diagnostic efficiency of NLR and NLR + PII was statistically significant (Z = 2.36, P = .02 < .05). NLR, PII, SIRI, pairwise combinations, and NLR + PII + SIRI showed auxiliary diagnostic values for bacteria-negative pulmonary TB, among which PII had the highest diagnostic value and specificity, while NLR + PII had the highest sensitivity.

Abstract
PURPOSE Previous work has focused on the role of diabetes in peripheral neuropathy (PN), but PN often occurs before, and independently from, diabetes. This study measures the association of cardiometabolic and inflammatory factor with PN, independent of diabetes. METHODS Study of Women's Health Across the Nation participants (n = 1910), ages 60 to 73 (mean 65.6) were assessed for PN by symptom questionnaire and monofilament testing at the 15th follow-up visit (V15). Anthropometric measures and biomarkers were measured at study baseline approximately 20 years prior, and C-reactive protein (CRP) and fibrinogen were measured longitudinally. Log-binomial regression was used to model the association between metabolic syndrome (MetS), obesity (≥35 body mass index), CRP, and fibrinogen with PN, adjusting for sociodemographic and health behavior measures. RESULTS Baseline MetS [prevalence ratio (PR) 1.79, 95% CI (1.45, 2.20)], obesity [PR 2.08 (1.65, 2.61)], median CRP [PR 1.32 per log(mg/dL), (1.20, 1.45)], and mean fibrinogen (PR 1.28 per 100 mg/dL, (1.09, 1.50)] were associated with PN symptoms at V15. After excluding participants with baseline diabetes or obesity, MetS [PR 1.59 (1.17, 2.14)] and CRP [PR 1.19 per log(mg/dL), (1.06, 1.35)] remained statistically significantly associated with PN. There was a negative interaction between MetS and obesity, and the association between these conditions and PN was mediated by CRP. CONCLUSIONS Cardiometabolic factors and inflammation are significantly associated with PN, independent of diabetes and obesity. CRP mediates the relationship of both obesity and MetS with PN, suggesting an etiological role of inflammation in PN in this sample.

Abstract
BACKGROUND Liver transplantation is a high-risk surgery associated with important perioperative bleeding and transfusion needs. Uncertainties remain on the association between preoperative fibrinogen level and bleeding in this population. METHODS We conducted a cohort study that included all consecutive adult patients undergoing a liver transplantation for end-stage liver disease in 1 center. We analyzed the association between the preoperative fibrinogen level and bleeding-related outcomes. Our primary outcome was intraoperative blood loss, and our secondary outcomes were estimated perioperative blood loss, intraoperative and perioperative red blood cell transfusions, reinterventions for bleeding and 1-y graft and patient survival. We estimated linear regression models and marginal risk models adjusted for all important potential confounders. We used restricted cubic splines to explore potential nonlinear associations and reported dose-response curves. RESULTS We included 613 patients. We observed that a lower fibrinogen level was associated with a higher intraoperative blood loss, a higher estimated perioperative blood loss and a higher risk of intraoperative and perioperative red blood cell transfusions (nonlinear effects). Based on an exploratory analysis of the dose-response curves, these effects were observed below a threshold value of 3 g/L for these outcomes. We did not observe any association between preoperative fibrinogen level and reinterventions, 1-y graft survival or 1-y patient survival. CONCLUSIONS This study suggests that a lower fibrinogen level is associated with bleeding in liver transplantation. The present results may help improving the selection of patients for further studies on preoperative fibrinogen administration in liver transplant recipients with end-stage liver disease.

Abstract
The Sysmex CN-6000 is a novel automated multiparameter coagulometer that performs clotting, chromogenic and immunological assays, and platelet aggregation tests in a single system. Here we evaluated its performance of routine coagulation assays. The precision, linearity, carryover and establishment of reference ranges of the CN-6000, as well as correlations between it and the currently used Diagnostica Stago STA-R Max were determined according to Clinical and Laboratory Standards Institute guidelines. The evaluated parameters included prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FBG), antithrombin (AT), d-dimers (DDi), and fibrin and FBG degradation products (FDP). The intra-run and inter-run precisions of the six tests were determined using normal and pathological control materials; all coefficients of variation were acceptable and within the allowable ranges. The CN-6000 showed excellent linearity for FBG, AT, DDi, and FDP (R = 0.999-1.00). Passing-Bablok regression (R2 > 0.95) demonstrated good agreement between the analyzers. In the carryover study, APTT, PT, FBG, AT, DDi, and FDP values were all acceptable. The establishing reference intervals revealed that each manufacturer's range was acceptable. Significant differences were observed in the APTT reference range because of using different detection systems and reagents. The CN-6000 analyzer showed reliable performance and good correlation with the currently used STA-R Max automated hemostatic analyzer. As CN-6000 uses an optical clot-detection method, its reference ranges for PT and APTT are lower than those of the STA-R Max; thus, the difference should be considered before its use.

Abstract
RATIONALE Discrimination is a risk factor and potential pathway through which social determinants such as race and sex contribute to chronic inflammation in Black Americans in middle and later adulthood. Questions remain regarding which forms of discrimination are most salient for inflammatory dysregulation, and whether there are sex-based differences in these pathways. OBJECTIVE This exploratory study investigates sex differences in the relationships between four forms of discrimination and inflammatory dysregulation among middle aged and older Black Americans. METHODS Using cross-sectionally linked data from participants in the Midlife in the United States (MIDUS II) Survey (2004-2006) and Biomarker Project (2004-2009) (N = 225, ages 37-84, 67% female), this study conducted a series of multivariable regression analyses. Inflammatory burden was measured using a composite indicator comprised of five biomarkers: C-reactive protein (CRP), interleukin-6 (IL-6), fibrinogen, E-selectin, and intercellular adhesion molecule (ICAM). Discrimination measures were lifetime, daily, and chronic job discrimination and perceived inequality at work. RESULTS Black men generally reported higher levels of discrimination than Black women (3 out of 4 forms), though only sex differences in job discrimination achieved statistical significance (p < .001). In contrast, Black women exhibited more overall inflammatory burden than Black men (2.09 vs. 1.66, p = .024), particularly elevated levels of fibrinogen (p = .003). Lifetime discrimination and inequality at work were associated with higher levels of inflammatory burden, after adjusting for demographic and health factors (p = .057 and p = .029, respectively). The discrimination-inflammation relationships further varied by sex, such that more lifetime and job discrimination predicted greater inflammatory burden in Black women, but not in Black men. CONCLUSION These findings highlight the potentially detrimental impact of discrimination and emphasize the importance of sex-specific research on biological mechanisms of health and health disparities in Black Americans.
