Abstract
AIM To explore possible inter-relationships of various biomarkers of inflammation and lifestyle and other cardiovascular risk factors (age, gender, smoking history, hypertension, Type 2 diabetes, dyslipidemia, alteration of circadian rhythms, body mass index, calf circumference, thigh circumference, abdominal circumference) in the Mugello study oldest old. METHODS In 399 noninstitutionalized nonagenarians (291 women), whole blood cells, mean platelet volume, C-reactive protein, uric acid, gamma-glutamyl transferase were assessed. RESULTS Aging resulted as the only independent determinant for uric acid (<0.05), and abdominal circumference for C-reactive protein. Female gender (<0.01), and thigh circumference (<0.05) remained as determinants for mean platelet volume, age (<0.01), and male gender (<0.01) for gamma-glutamyl transferase, and Type 2 diabetes (≤0.01) and alteration of circadian rhythms (<0.05) for whole blood cells. CONCLUSION Several inflammatory parameters remain associated with adverse lifestyle and cardiovascular risk factors even among nonagenarians.

Risk Analysis of Prostate Cancer Treatments in Promoting Metabolic Syndrome Development and the Influence of Increased Metabolic Syndrome on Prostate Cancer Therapeutic Outcome. Discov Oncol 2018; 9:278-287.

Abstract
In clinical practice, few prostate cancer (PCa) patients are associated with metabolic syndrome (MetS), while few others acquire MetS during treatment. Whether the treatment of PCa increases the occurrence of MetS remains to be confirmed. This study reviewed the changes in MetS patients before and after PCa treatment to evaluate the effects of various treatment methods on MetS. We analyzed data of 1162 PCa patients, whether or not diagnosed with MetS, and changes in MetS patients after PCa treatment. Data of lower urinary tract symptoms, C-reactive protein (CRP), platelet distribution width (PDW), prostate-specific antigen (PSA), Gleason score, clinical stage, treatment methods, and progressive incidents were evaluated using logistic regression according to MetS diagnosis. The results showed significant differences in the prevalence of MetS before (17.38%) and after (23.67%) PCa treatment (P < 0.001). Bad diet, living habits, and prostate cancer treatment were considered as risk factors for MetS (OR = 1.731, 95%CI 1.367-2.193, P < 0.001). Radical prostatectomy (RP), androgen deprivation therapy including surgical castration and medical castration, iodine-125 seed brachytherapy (125I limited), and chemotherapy were independent risk factors of MetS. The MetS incidence rates after treatment in ADT+125I limited+chemotherapy compared to RP+TURP+EBRT were statistically significant at the corresponding risk grade (all P < 0.001). After treatment, the occurrence rates of progressive incidences were higher in MetS-PCa patients compared to non-MetS-PCa patients (all P < 0.001). So, the findings suggested that among PCa patients, multiple factors contribute to the occurrence of MetS, and PCa treatment is one among them. ADT+125I limited+chemotherapy may be the most influential treatment for MetS.

Abstract
BACKGROUND Most of prior studies to demonstrate the association between mean platelet volume (MPV) and type 2 diabetes mellitus (T2DM) risk were cross-sectional design with inconsistent results. In the present prospective cohort study, we aimed to explore the relationship between MPV and incident T2DM risk among a middle-aged and older Chinese population. METHODS This prospective study included 14,009 individuals derived from the Dongfeng-Tongji cohort which was launched in 2008. A total of 997 incident T2DM patients were diagnosed during the mean 4.51 years of follow-up period. MPV levels were divided into quartiles. The adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) of incident T2DM was estimated by Cox proportional hazard models. RESULTS Compared with study participants with MPV < 7.49 fL, the HRs of T2DM incidence were 1.39 (95% CI 1.11-1.75), 1.14 (0.90-1.44), and 1.39 (95% CI 1.07-1.81) in study participants with 7.49 ≤ MPV < 8.43 fL, 8.43 fL ≤ MPV < 9.69 fL and MPV ≥ 9.69 fL, respectively. This positive association was more pronounced after exclusion of the newly diagnosed incident cases during the first 2 years follow-up. Further adjustment for baseline fasting blood glucose level (FBG) did not materially alter the positive association. The positive association was particularly evident among females, non-current smokers and study participants with FBG level less than 5.6 mmol/L at baseline. CONCLUSION Higher levels of MPV were independently associated with increased incident risk of T2DM in a middle-aged and older Chinese population.

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.

Abstract
BACKGROUND AND AIMS The relationship between platelet indices and glucose control may differ in type 1 (T1DM) and type 2 (T2DM) diabetes. We aimed to investigate differences in mean platelet volume (MPV), platelet count, and platelet mass between patients with T1DM, T2DM, and healthy controls and to explore associations between these platelet indices and glucose control. METHODS AND RESULTS A total of 691 T1DM and 459 T2DM patients and 943 control subjects (blood donors) were included. HbA1c was measured in all subjects with diabetes and 36 T1DM patients further underwent 24 h-continuous glucose monitoring to estimate short-term glucose control (glucose mean and standard deviation). Adjusting for age and sex, platelet count was higher and MPV lower in both T1DM and T2DM patients vs control subjects, while platelet mass (MPV × platelet count) resulted higher only in T2DM. Upon further adjustment for HbA1c, differences in platelet count and mass were respectively 19.5 × 109/L (95%CI: 9.8-29.3; p < 0.001) and 101 fL/nL (12-191; p = 0.027) comparing T2DM vs T1DM patients. MPV and platelet count were significantly and differently related in T2DM patients vs both T1DM and control subjects; this difference was maintained also accounting for HbA1c, age, and sex. Platelet mass and the volume-count relationship were significantly related to HbA1c only in T1DM patients. No associations were found between platelet indices and short-term glucose control. CONCLUSION By accounting for confounders and glucose control, our data evidenced higher platelet mass and different volume-count kinetics in subjects with T2DM vs T1DM. Long-term glucose control seemed to influence platelet mass and the volume-count relationship only in T1DM subjects. These findings suggest different mechanisms behind platelet formation in T1DM and T2DM patients with long-term glycaemic control being more relevant in T1DM than T2DM.

Abstract
Few reports have analyzed the effect of pentraxin 3 (PTX3) on platelets and their activation. We explored the association between plasma PTX3 and platelet indices. Forty-nine patients with stable coronary artery disease (CAD) were enrolled. Based on median PTX3, the study population was divided into group 1 (n = 25; PTX3 ≤ 0.98 ng/mL) and group 2 (n = 24; PTX3 > 0.98 ng/mL). Platelet indices investigated included mean platelet volume (MPV), platelet distribution width (PDW), platelets and large cell ratio (P-LCR), MPV to platelet count ratio (MPV/PC), platelet to lymphocyte ratio (PLR), and MPV to lymphocyte ratio (MPVLR). Patients with lower PTX3 had a higher lymphocyte count. Platelet count was similar in both groups. Notwithstanding, patients with higher PTX3 concentrations had elevated MPV (8.3 vs 10.0 fL; P < .001) and PDW (9.4 vs 12.4 fL; P < .001). However, the MPV/PC ratio was similar in both groups. Thromboinflammatory biomarkers (PLR, MPVLR) were also elevated in group 2. Pentraxin 3showed a strong, positive correlation with MPV ( r = .75, P < .01) and PDW ( r = .80, P < .01), and weak to moderate correlation with MPVLR. In conclusion, PTX3 is associated with larger platelet size as assessed by platelet volume indices. There is a strong correlation between plasma PTX3 level and MPV and PDW.

Abstract
BACKGROUND Serum annexin A5 (anxA5) level is significantly increased in patients with acute coronary syndrome. Hematological indices are significantly increased in patients with ischemic heart disease. This study aimed to demonstrate the changes in the distribution of blood cells and the levels of anxA5 in patients presented with significant low ejection fraction ST-elevation acute myocardial infarction (STEMI) in comparison with corresponding patients with ischemic heart disease. METHODS Patients with low ejection fraction presenting at Hospital of Diyala University of Iraq were enrolled. Electrocardiograph (ECG), echocardiograph, hematological indices, serum annexin V (anxV) levels and the determinants of the cardio-metabolic risk factors were performed. Based on clinical examination, ECG findings and laboratory tests, patients were divided into healthy subjects (n=20); patients with acute MI (n=40) and with chronic MI (n=12). RESULTS Acute MI has significant high levels of serum triglyceride, uric acid and high mean value of red cell distribution width (RDW) compared with healthy subjects and chronic MI. Platelet distribution width (PDW) is significantly reduced in patients of acute MI and chronic MI compared with healthy subjects, whereas the plateletcrit (PCT) is significantly higher in acute MI compared with healthy subjects. There is an insignificant difference between the means of serum anxA5 levels of acute MI (35.6±7.2ng/ml) and chronic MI (32.4±8.9ng/ml), but significantly higher than the cutoff level of the healthy subjects (5ng/ml). CONCLUSIONS Measurement of serum annexin level is a useful diagnostic marker of acute or chronic MI with low ejection fraction.

Abstract
INTRODUCTION Platelets are tiny, disc-shaped, non-nucleated structures derived from megakaryocytes. The morphological differences in measuring Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW) of platelets have important implications for assessing the functional expressions of platelets. Electron microscopy reveals the presence of glycogen as prominent masses in platelets. MPV values have been generally reported to be very high in individuals with uncontrolled diabetes mellitus (DM). AIM This study aimed to determine and compare the MPV values in uncontrolled and controlled group of Type-2 Diabetics along with healthy non-diabetic people and to correlate MPV values with age, sex and glycosylated haemoglobin (HbA1c) levels in diabetic groups. This study also aimed to determine the prevalence of retinopathy in uncontrolled and controlled group of diabetic patients. MATERIALS AND METHODS This case control study was carried out in our institution for 1 year. The patients were grouped as uncontrolled group of diabetic patients and controlled group of diabetic patients based on their HbA1c levels. 106 uncontrolled diabetic patients and 100 controlled diabetic patients were included, with 100 non-diabetic subjects as controls. Patient's profile which included all demographic particulars and medical history was obtained. Fundus examination and other ophthalmic findings of 50 uncontrolled and 50 controlled diabetic cases were recorded. The findings were analysed statistically using IBM SPSS software. RESULTS In uncontrolled group of 106 diabetic patients, 54 patients were males and 52 patients were females and the mean age was 51.63±11.04, mean HbA1c was 9.86±1.91% and mean MPV was 8.93±0.90fl. In controlled group of 100 diabetic patients, 49 patients were males and 51 patients were females and the mean age was 47.88±15.17, mean HbA1c was 6.08±0.49% and mean MPV was 8.106 ± 0.72fl. In 100 non-diabetic controls 77 patients were males and 23 patients were females and the mean age was 37.97±9.69 and mean MPV was 8.02±0.86fl. Among 50 cases of uncontrolled DM, 14 uncontrolled DM patients had diabetic retinopathy with an average MPV of about 9.2±0.61fl and mean HbA1c of 10.6±1.98% whereas, 30 uncontrolled patients with no evidence of retinopathy with an average MPV of about 8.39±0.676 fl and mean HbA1C of 9.18±1.91%. CONCLUSION MPV values are higher in uncontrolled DM patients when compared with controlled DM patients and a higher percentage of them develop microvascular complications like Diabetic Retinopathy suggesting that mean platelet volume could indicate and play a more important role in the detection of vascular complications of Diabetes.

Abstract
BACKGROUND AND OBJECTIVES Leukocyte and platelet have been found to be associated with metabolic syndrome (MetS). We aimed to determine the usefulness of a novel marker named white blood cell count to mean platelet volume ratio (WMR) for predicting outcomes of non-ST elevation acute coronary syndrome (NSTE-ACS) with or without MetS. SUBJECTS AND METHODS A total of 331 NSTE-ACS individuals (60±12.5 years, 57.4% male) were enrolled and followed for a median of 24 months. MetS was identified using the National Cholesterol Education Program Adult Treatment Panel III criteria. RESULTS Patients were divided into two groups: high WMR (WMR≥720) and low WMR (WMR<720). Major adverse cardiovascular events (MACE) and MetS rates were significantly greater in the higher WMR group compared to those in the low WMR group (MACE: 14.3% vs. 25%, p=0.014; MetS: 50.9% vs. 75%, p<0.001). MetS was diagnosed in 62.2% of patients. MACE incidence in patients with or without MetS was comparable (p=0.737). Among MetS individuals, patients in the high WMR group had more MACE than the low WMR group (11.2% vs. 26.5%, p=0.007). However, MACE was comparable among non-MetS individuals (p=0.681). In multivariable Cox regression analysis, hazard ratios (HR) of MACE incidence for high-WMR in MetS individuals was 2.616 (95% confidence interval: 1.282-5.339, p=0.008). However, HR of MACE incidence for high WMR in non-MetS individuals was not significant. CONCLUSION Among NSTE-ACS patients without revascularization therapy, elevated admission WMR was associated with an increased risk of developing composite MACE in MetS individuals but not in non-MetS patients.

Abstract
Gestational diabetes is the most encountered metabolic disease in pregnancy and affects both the mother and fetus adversely. Low-grade subchronic inflammation is associated with gestational diabetes development. Platelets (PLT) play role in blood coagulation and inflammatory process. We aimed to compare the various platelet indices in patients with GDM and healthy pregnant controls and to determine whether PLT indices are useful in Gestational diabetes diagnosis. The present study was performed at the Zonguldak Bulent Ecevit University, School of Medicine, Department of Obstetrics and Gynecology. Statistically significant relationships with plateletcrit, mean platelet volume, and platelet distribution width and patients with GDM were found (p < 0.001). Plateletcrit had higher sensitivity and specificity than other platelet indices. Although plateletcrit is a largely unknown or an underestimated parameter in complete blood count, it gives more precise information than platelet count and mean platelet volume. Platelet-related indices and their determination are inexpensive and routinely ordered markers, the significance of which is often ignored. They may be useful in screening for gestational diabetes as an adjunct to oral glucose tolerance test.

Abstract
AbstractBackground:Platelet volume indices (PVI), an easy and inexpensive surrogate measure of platelet function, have been associated with cardiovascular diseases (CVD) and their risk factors. However, results are conflicting because of the lack of standardized procedures. The purpose of this study is to investigate the relationship of PVI with the Framingham risk score (FRS).Methods:Baseline data (2008–2010) of 3115 participants enrolled in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) were used. PVI measurements were strictly controlled. The cohort was distributed according to risk factors and the general FRS was estimated. Multiple linear regression analysis was used to estimate the association between PVI and FRS.Results:Mean platelet volume (MPV), platelet distribution width (PDW) and platelet large cell ratio (P-LCR) independently correlated (p≤0.01) with FRS after adjustment for confounding variables. One unit increase in MPV, PDW, or P-LCR increased the FRS by 0.59%, 0.40%, and 0.08%, respectively. Diabetics had higher (p≤0.004) MPV, PDW, and P-LCR, and hypertensive individuals had higher (p≤0.045) PDW and P-LCR.Conclusions:Increased PVI was independently correlated with higher CVD risk based on the FRS, diabetes, and systolic hypertension. Prospective follow up of this cohort is warranted to confirm that PVI is associated with the development of CVD.

Abstract
Diabetes imparts a substantial increased risk for cardiovascular disease-related mortality and morbidity. Because of this, current medical guidelines recommend prophylactic treatment with once-daily, low-dose aspirin (acetylsalicylic acid) for primary and secondary prevention of cardiovascular (CV) events in high-risk patients. However, only modest reductions in CV events and mortality have been observed with once-daily aspirin treatment in patients with diabetes, including patients with a previous CV event, perhaps because of disparity between aspirin pharmacokinetics and diabetes-related platelet abnormalities. Once-daily aspirin irreversibly inactivates platelets for only a short duration (acetylsalicylic acid half-life, approximately 15-20 minutes), after which time newly generated, active platelets enter the circulation and weaken aspirin's effect. Platelets from patients with diabetes are more reactive and are turned over more rapidly than platelets from normal individuals; the short inhibitory window provided by once-daily aspirin may therefore be insufficient to provide 24-h protection against CV events. Alternative conventional aspirin regimens (e.g. higher daily dose, twice-daily dosing, combination with clopidogrel) and newer formulations (e.g. 24-h, extended-release) have been proposed to overcome the apparent limited efficacy of conventional aspirin in patients with diabetes; however, tolerability concerns and limited clinical efficacy data need to be taken into account when considering the use of such regimens.

Abstract
Current treatment guidelines recommend once-daily, low-dose acetylsalicylic acid (ASA; aspirin) for secondary prevention of cardiovascular events. However, the anti-thrombotic benefits of traditional ASA formulations may not extend over a 24-h period, especially in patients at high risk for a recurrent cardiovascular event. A next-generation, extended-release ASA formulation (ER-ASA) has been developed to provide 24-h anti-thrombotic coverage with once-daily dosing. The pharmacokinetics of ER-ASA indicates slower absorption and prolonged ASA release versus immediate-release ASA, with a favorable safety profile. ER-ASA minimizes systemic ASA absorption and provides sustained antiplatelet effects over a 24-h period.
