Beyond the fractures: A comprehensive Comparative analysis of Affordable and Accessible laboratory parameters and their coefficients for prediction and Swift confirmation of pulmonary embolism in high-risk orthopedic patients. Pract Lab Med 2024; 40:e00397. [PMID: 38737854 PMCID: PMC11088337 DOI: 10.1016/j.plabm.2024.e00397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 04/25/2024] [Accepted: 04/26/2024] [Indexed: 05/14/2024] Open
Abstract
Background Pulmonary embolism (PE) poses a significant challenge in diagnosis and treatment, particularly in high-risk patient populations such as those hospitalized for orthopedic reasons. This study explores the predictive and diagnostic potential of laboratory parameters in identifying PE among orthopedic patients. Objectives The purpose of this study was to determine whether selected (inexpensive and readily available) laboratory parameters and their coefficients can be used to diagnose pulmonary embolism and whether they are applicable in predicting its occurrence. Material and methods Selected laboratory parameters were determined twice in 276 hospitalized orthopedic patients with suspected PE: PLT, MPV, NEU, LYM, D-dimer, troponin I, age-adjusted D-dimer and their coefficients. Depending on the angio-CT results, patients were divided into groups. Selected popular laboratory coefficients were calculated and statistically analyzed. Optimal cutoff points were determined for the above laboratory tests and ROC curves were plotted. Results D-dimer/troponin I [p = 0.008], D-dimer [p = 0.001], age-adjusted D-dimer [p = 0.007], NLR/D-dimer [p = 0.005] and PLR [p = 0.021] are statistically significant predictors of PE. D-dimer/troponin I [p < 0.001], troponin I [p = 0.005] and age-adjusted D-dimer [p = 0.001] correlated with the diagnosis of PE after the onset of clinical symptoms. Conclusions In the context of orthopedic patients, cost-effective laboratory parameters, particularly the D-dimer/troponin I ratio and age-adjusted D-dimer, exhibit considerable potential in predicting and diagnosing PE. These findings suggest that combining readily available laboratory tests with clinical observation can offer a viable and cost-effective diagnostic alternative, especially in resource-constrained settings. Further studies with larger and diverse patient populations are recommended to validate these results.

Abstract
BACKGROUND While mean platelet volume (MPV) is linked to severity and all-cause mortality in patients with sepsis, its association with all-cause mortality and cardiovascular mortality in patients treated with peritoneal dialysis (PD) remains unknown. OBJECTIVES The purpose of this study was to estimate the relationship between MPV and all-cause mortality and cardiovascular mortality among patients treated with PD. METHOD We retrospectively collected 1322 patients treated with PD from November 1, 2005 to August 31, 2019. All-cause mortality and cardiovascular mortality was identified as the primary outcome. MPV was classified into three categories by means of X-tile software. The correlation between MPV and all-cause mortality was assessed by Cox model. Survival curves were performed by Kaplan-Meier method. RESULTS The median follow-up period was 50 months (30-80 months), and a total of 360 deaths were recorded. With respect to all-cause mortality, patients in MVP ≥ 10.2 fL had considerably higher risk of all-cause mortality among three models (HR 0.68, 95%CI 0.56-0.84; HR 0.70, 95%CI 0.56-0.87; HR 0.73, 95%CI 0.59-0.91; respectively). Moreover, patients treated with PD, whose MVP ≥ 10.2 fL, also suffered from significantly higher risk of cardiovascular mortality in model 1, 2, and 3 (HR 0.63, 95%CI 0.46-0.85; HR 0.66, 95%CI 0.48-0.91; HR 0.69, 95%CI 0.50-0.95; respectively). CONCLUSIONS This study indicates that MPV is independently correlated with both all-cause mortality and cardiovascular mortality in PD.

Abstract
Ischemic stroke subtypes such as patients with large artery atherosclerosis, cardioembolism, and embolic stroke of undetermined source were investigated. This study was performed aimed to determine mean platelet volume (MPV) and mean platelet volume/platelet count (MPV/Plt) ratio in nonvalvular atrial fibrillation (AF) stroke and large artery atherosclerosis (LAA) stroke.We conducted a retrospective study of consecutive patients for treatment of acute ischemic stroke at Ruian People's Hospital from March 2017 to October 2018. The patients with ischemic stroke caused by AF and LAA were recruited to this study. Ischemic stroke was confirmed by magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), ischemic lesions on diffusion-weighted imaging were measured in terms of size, composition, and pattern. MPV and platelet count were examined and (MPV/Plt) ratio was calculated.Three hundred seventy one patients were enrolled composing of 177 (47.7%) nonvalvular AF and 194 (52.2%) with LAA. The MPV (11.3 ± 1.3 vs 10.8 ± 1.0, P < .001) and MPV/Plt ratio (0.066 ± 0.025 vs 0.055 ± 0.20, P < .001) were much higher in AF group than LAA group. Receiver-operating characteristic (ROC) analysis showed MPV (AUC: 0.624, confidence interval: 0.567-0.68, P < .001) and MPV/Plt (AUC: 0.657, confidence interval: 0.601-0.713, P < .001) predicted AF between the 2 groups. MPV/Plt ratio was negatively associated with lesion volume (r = -0.161, P = .033) in AF. The analyses of subtypes of composition of infarcts and infarct pattern showed that MPV/Plt ratio was almost higher in AF than LAA except for subcortical-only pattern. Multivariable regression analyses demonstrated National Institutes of Health Stroke Scale (NIHSS) score (r = 2.74; P < .001), LAD (r = -1.15; P = .025) and MPV/Plt ratio (r = -180.64; P = .021) were correlated with lesion volume.Our results indicated elevated MPV and MPV/Plt ratio for the identification of difference between AF and LAA in patients with ischemic stroke.

Abstract
Red blood cell distribution width (RDW) is a marker of variability in red blood cell size, and is routinely reported as part of a patient's complete blood count. RDW has been shown to be associated with the prediction, severity and prognosis of pulmonary embolism (PE) in recent studies. The underlying biomolecular mechanism of the relationship of RDW to PE is largely unknown, but is thought to be due to the relationship of RDW with acute inflammatory markers and variations in blood viscosity. This review substantiates that a high RDW level, defined using either an arbitrary number or according to receiver operator curve statistics, is associated with a higher risk of acute PE, increased severity (massive vs. submassive) of PE and increased mortality in patients with PE. Nevertheless, the comparison of current studies is limited due to the definition of high RDW (each study uses a different RDW cutoff level), the broad range of exclusion criteria and the inclusion of differing modalities used to diagnose a PE (computed tomography angiogram, ventilation-perfusion study, or clinical diagnosis). Despite the above limitations, these studies provide a promising future clinical use for RDW as a marker of PE.

Abstract
Introduction: Given the role of platelets in thrombus formation, markers of platelet activation may be able to predict outcomes in patients with acute pulmonary thromboembolism (PTE). Methods: In a prospective cohort study, 492 patients with acute PTE were enrolled. Patients were evaluated for platelet indices including mean platelet volume (MPV), platelet distribution width (PDW), and platelet-lymphocyte-ratio (PLR), as well as for the simplified Pulmonary Embolism Severity Index (PESI) risk score. The primary endpoint was in-hospital all-cause mortality. Major adverse cardiopulmonary events (MACPE, composite of mortality, thrombolysis, mechanical ventilation and surgical embolectomy during index hospitalization) and all-cause death during follow-up were secondary endpoints. Results: MPV, PDW and PLR were 9.9±1.0 fl, 13.5±6.1%, and 14.7±14.5, respectively, in the total cohort. Whilst MPV was higher in those with adverse events (10.1±1.0 vs 9.9±1.0 fl; P= 0.019), PDW and PLR were not different between two groups. MPV with a cut-off point of 9.85 fl had a sensitivity of 81% and a specificity of 50% in predicting in-hospital mortality, but it had lower performance in predicting MACPE (Area under the curve: AUC 0.58; 95%CI 0.52-0.63) or long-term mortality (AUC 0.54; 95% CI 0.47-0.61). The AUC for all these three markers were lower than the AUC calculated for the simplified PESI score (0.80; 0.71-0.88). Conclusion: Platelet indices had only fair-to-good predictive performance in predicting in-hospital all-cause death. Established PTE risk scoring models such as simplified PESI outperform these indices in predicting adverse outcomes.

Abstract
OBJECTIVES To investigate the prognostic values of preoperative platelet-to-lymphocyte ratio (PLR) and platelet-related indices in advanced hypopharyngeal squamous cell carcinoma (HPSCC). METHODS The data of 247 eligible advanced HPSCC patients were reviewed retrospectively. Pretreatment haematological parameters were categorised into two groups based on the result of X-tile, and several variates were assessed using chi-square test, Kaplan-Meier method, Cox univariate and multivariate analysis. RESULTS The optimal cut-off points of 171.4 for PLR, 260 × 109 /L for platelet, 10.4 fL for mean platelet volume (MPV) and 16.5% for platelet distribution width were defined. The haematological parameters PLR and MPV, postoperative metastasis and internal jugular vein invasion were statistically significant in OS and DFS analyses (P < .05). The high PLR (>171.4) or high MPV (>10.4 fL) was significantly associated with worse OS and DFS (P < .05). CONCLUSIONS The preoperative levels of PLR and MPV could be considered as independent prognostic predictors in patients with advanced HPSCC.

Abstract
Introduction Chronic obstructive pulmonary disease (COPD) is a complex inflammatory condition that can affect haemostasis. This study aimed to determine differences in platelet-related parameters between controls and COPD subjects. The hypothesis was that platelet indices are disturbed in COPD patients, and this would be accompanied by increased C-reactive protein (CRP), fibrinogen (Fbg) and white blood cells (WBC). Therefore, platelet count (Plt), platelet-related parameters - mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (Pct), their ratios (MPV/Plt, MPV/Pct, PDW/Plt, PDW/Pct), platelet to lymphocyte ratio (PLR), Plt index as well as CRP, Fbg and WBC were assessed. Materials and methods Study included 109 patients with stable COPD and 95 control subjects, recruited at Clinical Department for Lung Diseases Jordanovac, University Hospital Centre Zagreb (Zagreb, Croatia). Complete blood count was performed on Sysmex XN-1000, CRP on Cobas c501, and Fbg on BCS XP analyser. Data were analysed with MedCalc statistical software. Results Platelet (P = 0.007) and PLR (P = 0.006) were increased, while other platelet indices were decreased in COPD patients compared to controls. Combined model that included PLR, PDW and WBC showed great diagnostic performances, and correctly classified 75% of cases with an AUC of 0.845 (0.788 - 0.892), P < 0.001. Comorbidities (cardiovascular or metabolic diseases) had no effect on investigated parameters, while inhaled corticosteroids/long-acting β2-agonists (ICS/LABA) therapy increased MPV and PDW values in COPD patients. Conclusion Platelet indices were altered in COPD patients and they could be valuable as diagnostic markers of COPD development, especially if combined with already known inflammatory markers.

Abstract
Background and Objectives: The mean platelet volume (MPV) represents a possible marker of platelet activation. There is an association between the platelet count (PC) and inflammation and platelet reactivity. We assessed the association between the MPV/PC ratio and circadian alterations in blood pressure (BP). Material and Methods: One hundred and twenty subjects in total, 80 hypertensive subjects and 40 healthy subjects (controls), were enrolled in the study group. Twenty four hour ambulatory BP monitoring (ABPM) was applied to all subjects. According to ABPM results, the hypertensive subjects were separated into two groups, such as dippers (n = 40) and non-dippers (n = 40). In all subjects, the collection of venous peripheral blood samples was performed on admission for PC and MPV measurements. Results: The two groups exhibited similar clinical baseline characteristics. A significantly higher MPV/PC ratio was determined in non-dippers compared to that in dippers and normotensives. The higher MPV/PC ratio was observed in non-dippers in comparison with that in dippers and normotensives (0.046 ± 0.007 to 0.032 ± 0.004 fL/[109/L]; 0.046 ± 0.007 to 0.026 ± 0.004 fL/[109/L], p < 0.001, respectively). A receiver operating characteristic (ROC) curve analysis showed that the optimum cut-off value of the MPV/PC ratio for predicting non-dipping patterns in hypertensive patients was 0.036 (area under the curve [AUC]: 0.98, p < 0.001). According to the cut-off value, sensitivity and specificity were found to be 95% and 95%, respectively. Conclusions: The higher MPV/PC ratio was determined in non-dipper hypertensive subjects in comparison with that in dipper hypertensive subjects. An elevation of platelet activity and an increase in thrombus burden are reflected by an increase in the MPV/PC ratio. The MPV/PC ratio may underlie the increase in cardiovascular risk in non-dippers compared to that in dippers.

Abstract
Introduction: Rheumatic heart disease (RHD) is a relatively common cause of mortality among patients in the developing countries, and pure mitral valve failure is the most common form of RHD. An increase in the mean platelet volume (MPV) is considered as an independent risk factor for many cardiovascular diseases. This study aimed to evaluate the association of MPV with echocardiographic findings in patients with severe rheumatic mitral stenosis. Methods: In a descriptive, analytical study, 100 patients with severe rheumatic mitral stenosis referred to Shahid Madani hospital of Tabriz University of Medical Sciences and 100 age & sex-matched healthy individuals were included the study. MPV and echocardiographic findings including Wilkins score, left ventricular ejection fraction (LVEF), pulmonary artery systolic pressure, and left atrial spontaneous echo contrast (LASEC) were evaluated in both groups. Results: MPV in the case group was 10.45±0.98 and in the control group was 9.88±0.83. MPV in the patient's groups was significantly higher than the control group (P = 0.001). Also, MPV in patients with positive LASEC findings was 10.69 ± 1.01 and in patients with negative LASEC findings was 10.25 ± 0.91. The difference was found to be statistically significant (P = 0.028). Conclusion: Patients with rheumatic mitral stenosis has a higher MPV compared to the healthy individuals, and it is associated with LASEC sign seen in echocardiography.

Abstract
Introduction: Early diagnosis of pulmonary thromboembolism (PTE) is crucial in clinical medicine. Many para-clinical measurements are used to diagnose PTE. Objective: The present study was conducted to evaluate platelet indices in terms of diagnosing PTE. Methods: The present case-control study was conducted between May 2015 to July 2016 with 173 patients suspected of PTE in the emergency wards of Shahid Madani Hospital and Imam Reza Hospital affiliated to Tabriz University of Medical Sciences, Iran. The patients’ platelet indices were checked upon admission and they were evaluated in terms of diagnosing PTE. Platelet indices included mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PL-CR). PTE was diagnosed in 125 out of the 173 patients. Platelet indices were also compared between two groups. Results: No statistically significant differences were observed between the two groups in term of demographic variables (p>0.05). MPV was found to be 10.38±8.59 in the case group and 9.46±1.11 in the controls (p>0.05). PDW was also found to be 12.86±5.57 in the case group and 12.32±2.48 in the controls (p>0.05). Moreover, PL-CR was found to be 22.59±7.32 in the case group and 21.97±8.16 in the controls (p>0.05). Conclusion: According to the obtained results, platelet indices do not increase in PTE. They cannot be therefore used to diagnose PTE in suspected patients.

Abstract
BACKGROUND The aim of this study was to investigate the value of the mean platelet volume to platelet count (MPV/P) ratio for predicting in-hospital and long-term cardiac mortality in older non-ST elevation-acute coronary syndrome (NSTE-ACS) patients after primary percutaneous coronary intervention (PCI). METHODS We retrospectively reviewed 452 older NSTE-ACS patients who received primary PCI. The patients were divided into two groups based on MPV/P ratios: high MPV/P group (N.=150) defined as a value in the third tertile (>0.056628) and low MPV/P group (N.=302) in the lower two tertiles (≤0.056628). Clinical outcomes included non-fatal reinfarction, heart failure, and cardiac mortality. RESULTS Multivariate analyses showed that high MPV/P and MPV values were independent predictors of cardiac mortality. The in-hospital cardiac mortality of the high MPV/P group was higher than the low MPV/P group (1.3% vs. 14.7%, P<0.001). The rates of heart failure and cardiac mortality in one year were significantly higher in the high MPV/P group compared to the low MPV/P group (P<0.05). The cut-off value of MPV/P for predicting cardiac death was 0.067107, with a sensitivity of 0.707 and a specificity of 0.868. MPV/P was superior to MPV (z=9.235, P<0.001) for predicting cardiac mortality. CONCLUSIONS High MPV/P and MPV values are independent predictors of cardiac mortality in older patients with NSTE-ACS receive primary PCI. Moreover, MPV/P is better than MPV for predicting cardiac mortality.

Abstract
BACKGROUND Wells and Geneva scores are widely used in the assessment of pretest probability of pulmonary embolism (PE). OBJECTIVE The objective of this study was to examine the hypothesis that mean platelet volume (MPV) may better predict PE than the clinical prediction rules. METHODS A study was performed among patients with PE. Baseline characteristics and complete blood counts including MPV were prospectively recorded upon admission. To assess clinical probability in patients with PE risk, we used Wells and Geneva scores. RESULTS Data records of 136 patients (males: 44%) with median age of 66 years (interquartile range [IQR] 57.5-78.0) diagnosed with PE at the Intensive Cardiac Therapy Clinic in Lodz (Poland) were analyzed. Baseline characteristics indicate that patients suffered from arterial hypertension (65%), obesity (32%), and diabetes mellitus (24%). Furthermore, they reported active smoking (21%), prolonged immobilization (20%), major surgery (21%), pregnancy (4%), and oral contraceptives (9%). Patients presented with various symptoms. The MPV, plateletcrit, and D-dimer values on admission were respectively as follows: 10.71 (IQR 3.29-13.67), 0.2 (IQR 0.15-0.24), and 9.23 (IQR 8.5-9.85). The study revealed that Wells score correlated significantly with an elevated MPV value (P<0.05) per contra to Geneva score (P>0.05). According to our results, there is a lack of coherence between Wells and Geneva scores (P>0.05). Finally, we determined that the optimum MPV level cutoff point for PE on admission with reference to the original Wells score is 9.6 fL. CONCLUSION MPV may be considered useful as an adjunctive or independent predictive marker for PE used in lieu of clinical prediction rules.

Abstract
Background This study investigated the role of erythrocyte distribution width (RDW) and platelet distribution width (PDW) in evaluating the treatment efficacy for acute myocardial infarction (AMI). Material/Methods A total of 120 AMI patients receiving conventional myocardial infarction treatment were included. The patients were divided into an effective group and an ineffective group based on treatment efficacy. The RDW and PDW were measured before and after treatment. We used the independent samples t test, chi-square test, logistic regression, and ROC curves for analysis. Results The change and change rate of RDW and PDW were significantly improved (p<0.01) and the positive change rate of RDW, PDW, and RDW + PDW were significantly lower in the effective group compared with those in the ineffective group (p<0.01). The change and change rate of RDW and PDW are independent factors for treatment efficacy evaluation (p<0.05). ROC curve analysis showed that the changes and change rate of RDW and PDW were all significant in evaluating treatment efficacy (p<0.05). Conclusions The change and change rate of RDW and PDW or their combination can be used to evaluate treatment efficacy; however, the absolute value of RDW and PDW are not as significant.
