Platelet-associated biomarkers in nonalcoholic steatohepatitis: Insights from a female cohort with obesity. Eur J Clin Invest 2024; 54:e14123. [PMID: 37929908 DOI: 10.1111/eci.14123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 10/20/2023] [Accepted: 10/21/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND There is a lack of noninvasive diagnostic methods for nonalcoholic steatohepatitis (NASH), the severe condition of metabolic dysfunction-associated steatotic liver disease (MASLD). Platelet activation, evaluated through certain related parameters, is associated with liver disease and inflammation, but previous results are inconclusive. AIM To investigate the potential utility of platelet-related indices as noninvasive diagnostic markers for the detection and prediction of MASLD, focusing on NASH. RESULTS We found that mean platelet volume (MPV), plateletcrit (PCT) and platelet distribution width (PDW) were increased in the severe and morbidly obese (SMO) group compared to the normal weight (NW) group. We found decreased levels of MPV in steatosis and NASH patients. MPV and PCT values were decreased in the presence of mild liver inflammation. Platelet count (PLA) and PCT values were lower in the presence of ballooning. We obtained an area under the ROC curve of 0.84 using MPV and three other variables to predict MASLD. CONCLUSIONS Some platelet-related indices vary depending on liver condition. Here, we reported decreased MPV in MASLD presence. Moreover, we presented for the first time a predictive model using MPV, ALT levels and the presence of diabetes mellitus and metabolic syndrome to predict MASLD in obese women. Also, MPV is closely related to early liver inflammation in NASH, and PLA and PCT are related to hepatic ballooning. These indices could be widely used for the early detection of NASH since they are usually determined in routine laboratory tests.

Diabetes Metab Res Rev 2023; 39:e3641. [PMID: 37009687 DOI: 10.1002/dmrr.3641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 02/17/2023] [Accepted: 03/09/2023] [Indexed: 04/04/2023]
Abstract
AIMS Emerging evidence suggests that platelet count predicts the development of type 2 diabetes; however, there is conflicting evidence concerning the relationship in men and women. This study aimed to assess the longitudinal association between platelet count and the incidence risk of type 2 diabetes. MATERIALS AND METHODS Among 10,030 participants, 7325 participants (3439 men and 3886 women) without diabetes were selected from the Korean Genome and Epidemiology Study. Platelet count quartiles were divided as follows: Q1 ≤219, Q2, 220-254, Q3, 255-296 and Q4 ≥297 (x103 /ml) for men and ≤232, 233-266, 267-305 and ≥306 (x103 /μL) for women. The hazard ratios (HRs) with 95% confidential intervals (CIs) for incident type 2 diabetes were calculated using multiple Cox proportional hazards regression models according to sex-specific platelet count quartiles. RESULTS During the biennial follow-up period from 2001 to 2002 to 2013-2014, 750 male participants (21.8%, 750/3439) and 730 female participants (18.8%, 730/3886) had newly developed type 2 diabetes. For women, compared to the reference first quartile, the HRs for incident type 2 diabetes in the second, third, and fourth platelet count quartiles were 1.20 (0.96-1.50), 1.21(0.97-1.51), and 1.47 (1.18-1.82) after adjusting for age, body mass index, smoking status, alcohol intake, physical activity, mean arterial blood pressure, family history of diabetes, and HOMA-IR. However, these positive relationships were not observed in men after adjusting for the same co-variables. CONCLUSIONS Platelet count was independently associated with an increased risk of incident type 2 diabetes only in women.

Abstract
BACKGROUND Metabolic Syndrome (MetS) is a cluster of interconnected metabolic diseases. Hematological abnormalities are common but neglected complications of MetS. Thus, this study aimed to determine the magnitude of hematological abnormalities and their associated factors among MetS patients at the University of Gondar comprehensive specialized hospital, Northwest Ethiopia. METHOD A hospital-based cross-sectional study was conducted at the University of Gondar comprehensive specialized hospital from March to May 2022. A total of 384 MetS patients were selected using a systematic random sampling technique. Data were collected using pre-tested structured questionnaires and checklists. Anthropometric and blood pressure measurements were taken, and blood sample was collected for complete blood count determination. Stool and blood film examinations were performed to detect intestinal and malaria parasites, respectively. Data were entered into EpiData 3.1 and analyzed by Stata 14.0 software. Bivariate and multivariate logistic regression models were fitted to identify factors associated with hematological abnormalities. A p-value of < 0.05 was considered statistically significant. RESULTS The magnitude of anemia, leukopenia, leukocytosis, thrombocytopenia, and thrombocytosis was found to be 13.3%, 0.5%, 2.9%, 1.6%, and 2.3%, respectively. Being male (AOR = 2.65, 95% CI: 1.14, 6.20), rural residency (AOR = 5.79, 95% CI: 1.72, 19.51), taking antihypertensive medications (AOR = 3.85, 95% CI: 1.16, 12.78), having elevated triglyceride level (AOR = 2.21, 95% CI: 1.03, 4.75), and being overweight or obese (AOR = 0.32, 95% CI: 0.16, 0.64) were significantly associated with anemia. CONCLUSIONS Anemia was the most prevalent hematological abnormality identified in the present study, followed by leukocytosis and thrombocytosis. Anemia was a mild public health problem among MetS patients in the study area. Routine anemia screening for all MetS patients, especially for those with significant associated factors, may help in the early detection and effective management of anemia, which subsequently improves the patients' quality of life.

Abstract
BACKGROUND Hypertriglyceridemia is an independent risk factor for major adverse cardiovascular events, though the mechanisms linking triglycerides and platelet function with thrombosis, remain elusive. The aim of this study was to assess the association between platelet function and triglyceride levels. METHODS We included participants from the Framingham Heart Study Third Generation cohort, OMNI, and New Offspring Spouse cohort who attended the third examination cycle (2016-2019). Eligible participants were categorized into four triglyceride subgroups. RESULTS The study comprised a total of 1897 (55.53 %) participants with normal TG levels; 883 (25.85 %) participants with high-normal TGs; 378 (11.07 %) with borderline high TGs; and 258 (7.55 %) participants with hypertriglyceridemia. After adjusting for age, sex, alcohol consumption, aspirin, statin and P2Y12 inhibitors, the levels of ADP-induced platelet aggregation were inversely associated with total cholesterol levels (P < 0.0001). Platelet disaggregation was associated with low-density lipoprotein and high-density lipoprotein cholesterol levels (P < 0.0001). Lastly, in a shear-stress chamber assay mimicking arterial flow velocities, TG levels in the normal-high group were associated with increased levels of collagen-dependent thrombogenicity (β = 24.16, SE = 6.65, P < 0.0001). CONCLUSION Triglyceride levels are associated with altered platelet activation and aggregation. Furthermore, increased platelet-driven thrombogenicity is directly associated with triglyceride levels after adjusting for medications and other covariates.

Abstract
BACKGROUND Metabolic syndrome (MetS) is a global public health concern. Chronic inflammation plays a role in MetS; haematological inflammatory parameters can be used as MetS predicting factors. OBJECTIVE Hereditary and environmental factors play an important role in the development of MetS. This study aimed to determine the relationship between haematological parameters and MetS in the adult population of southeastern Iran, Kerman. METHODS This cross-sectional study was a sub-analysis of 1033 subjects who participated in the second phase of the Kerman Coronary Artery Disease Risk Factor Study (KERCADRS). Metabolic syndrome was diagnosed according to Adult Treatment Panel III (ATP III) definition. Pearson correlation coefficient was used to investigate the relationship between haematological parameters with age and components of metabolic syndrome. The role of WBC, neutrophil, lymphocyte and monocyte in predicting metabolic syndrome was evaluated using the receiver operating characteristic (ROC) curve. RESULTS White blood cell (WBC) and its subcomponent cells count, red cell distribution width (RDW), monocyte to HDL ratio (MHR) and Neutrophil to HDL ratio (NHR) had a significant positive correlation with the severity of MetS. The cut-off value of WBC was 6.1 (×103 /μL), the sensitivity was 70%, the specificity was 52.9% for females, the cut-off value of WBC was 6.3 (×103 /μL), the sensitivity was 68.2% and the specificity was 46.7%, for males. CONCLUSION WBC and its subcomponent count, RDW, MHR and NHR parameters are valuable biomarkers for further risk appraisal of MetS in adults. These markers are helpful in early diagnoses of individuals with MetS.

Abstract
Complete blood count (CBC) is one of the most common blood tests requested by clinicians and evaluates the total numbers and characteristics of cell components in the blood. Recently, many investigations have suggested that the risk of cancer, cardiovascular disease (CVD), arteriosclerosis, type 2 diabetes (T2DM), and metabolic syndrome can be predicted using CBC components. This review introduces that white blood cell (WBC), neutrophil-to-lymphocyte ratio (NLR), hemoglobin (Hb), mean corpuscular volume (MCV), red cell distribution width (RDW), platelet count, mean platelet volume (MPV), and platelet-to-lymphocyte ratio (PLR) are useful markers to predict CVD and metabolic diseases. Furthermore, we would like to support various uses of CBC by organizing pathophysiology that can explain the relationship between CBC components and diseases.

Abstract
Abstract
Background
Although mean platelet volume (MPV) has been reported to be associated with poor prognosis of various critical illness, the relationship between MPV and in-hospital mortality among patients undergoing invasive mechanical ventilation (IMV) is unclear.
Methods
A retrospective observational study including patients receiving IMV was conducted from January, 2014 to January, 2019. The patients were divided into two groups by MPV cutoff value. The receiver operating characteristics curve was used to evaluate the predictive ability of MPV for in-hospital mortality. Univariate and multivariate Cox regression analysis were conducted to analyze the value of MPV for predicting in-hospital mortality. Kaplan–Meier cumulative incidence curve was employed to observe the incidence of in-hospital mortality.
Results
A total of 274 patients were enrolled in the study, and 42 patients (15.3%) died in hospital. MPV > 11.4 fl was a valuable predictor for in-hospital mortality (AUC0.848; 95%CI, 0.800–0.889) with sensitivity 66.7%, and specificity = 86.21%. MPV > 11.4 fl was an independent risk factor for in-hospital mortality (adjusted HR 2.640, 95%CI, 1.208–5.767, P = 0.015). Compared to the group of MPV ≤ 11.4 fl, patients with MPV > 11.4 fl had increased mortality (log-rank test = 40.35, HR = 8.723, P < 0.0001). The relationship between MPV and in-hospital mortality was stronger in female patients than in male patients.
Conclusion
MPV > 11.4 fl is a more useful marker for predicting in-hospital mortality among critically ill patients receiving IMV, especially in female patients. Attention to the MPV marker is simple and profitable with immediate applicability in daily clinical practice.

Abstract
We investigated the platelet count (PLT), mean platelet volume (MPV), and plateletcrit (PCT) in dogs with type 1 diabetes mellitus (DM) compared to healthy controls, and their association with the major fraction of glycated hemoglobin (HbA1c). Blood samples from 33 clinically healthy dogs and 14 newly diagnosed diabetic dogs were included. CBCs were performed with the Advia 120; HbA1c was determined using a validated assay (Capillarys 2 flex-piercing; Sebia). Median [range] PLT and PCT were significantly higher (p = 0.040 and p = 0.010, respectively) in diabetic dogs (434 [176-987] × 109/L and 0.60 [0.26-1.22]%, respectively) compared to healthy dogs (297 [223-671] × 109/L and 0.35 [0.24-0.87]%, respectively]. Thrombocytosis was observed in 6 of 14 (43%) diabetic dogs. The median MPV was not significantly different (p = 0.114) between the diabetic (13.6 fL, 10.1-22.6 fL) and healthy dogs (11.9 fL, 8.6-19.1 fL). A significant, albeit weak, correlation was detected between HbA1c and PLT (rho = 0.298, p = 0.042) and PCT (rho = 0.340, p = 0.019), but no significant correlation was found with MPV (rho = 0.199, p = 0.180). Canine DM was associated with increased PLT and PCT, which was correlated with glycemic status. Our findings suggest dysregulated megakaryopoiesis in diabetic dogs, but this should be confirmed by large-scale studies, and the clinical implications should be investigated.

The mean platelet volume and atherosclerotic cardiovascular-risk factors in adults with obesity: a systematic review and meta-analysis of observational studies. BMC Nutr 2022; 8:47.

Abstract
BACKGROUND Obesity is a major risk factor for atherosclerotic cardiovascular disease (ASCVD) and is associated with altered platelet function. The mean platelet volume (MPV) is a rapid measure of platelet activation and a prognostic marker in patients with cardiovascular disease. However, no meta-analysis on the association between MPV and obesity has been conducted, and the value of monitoring the MPV in patients with obesity remains unclear. OBJECTIVE To provide cumulative evidence on whether the mean platelet volume (MPV) is increased in individuals with obesity and to describe associations between the ASCVD-risk factors and the MPV in individuals with obesity. METHODS This meta-analysis was prepared following the Meta-analysis Of Observational Studies (MOOSE) guidelines. We searched the PubMed and Embase database from inception until the 31st of March 2021. Studies were included when they reported the mean platelet volume in individuals with obesity and provided a suitable non-obese comparator group. The risk of bias was independently assessed by two reviewers using the Newcastle-Ottawa scale. The primary outcome of the meta-analysis was the MPV, while we considered the atherosclerotic risk profiles as a secondary outcome. RESULTS We identified 178 citations through the PUBMED and 255 citations through EMBASE database search. In all, 13 studies met the inclusion criteria. Firstly, we report an increased mean platelet volume in individuals with obesity compared to non-obese individuals (MD 0.79; [95%CI: 0.42 to 1.16], I2 = 93.4%). Moreover, the reported increase in the MPV was inversely associated with the body mass index (Coefficient: -0.57, standard error (SE): 0.18, p < 0.001) and directly related to changes in triglyceride levels (Coefficient: 4.99, standard error (SE): 1.14, p < 0.001). CONCLUSION This meta-analysis and meta-regression showed an increased MPV in nondiabetic individuals living with obesity. Moreover, the MPV was associated with hypertriglyceridemia, an independent predictor of atherosclerotic cardiovascular disease. Overall, the findings suggest that MPV may be a valuable rapid marker for the monitoring and risk-stratification of individuals with obesity who may be at risk of developing cardiovascular disease.

[PMID: 32886844 DOI: 10.1002/dmrr.3403] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 08/24/2020] [Accepted: 08/28/2020] [Indexed: 01/06/2023]
Abstract
AIMS The metabolic syndrome (MetS) is a major global problem, and inflammation and insulin resistance appear to be key underpinnings in this cardio-metabolic cluster. MetS predisposes to an increased risk of diabetes and atherosclerotic cardiovascular disease (ASCVD). It has a procoagulant diathesis which included increased platelet activity and impaired fibrinolysis. High density lipoprotein (HDL) appears to be anti-thrombotic. Accordingly, we examined the ratios between platelets to HDL-cholesterol(C) and adiponectin (Adipo) in patients with nascent MetS without the confounding of diabetes, ASCVD and smoking to determine their validity as biomarkers of MetS. METHODS Patients with nascent MetS (n = 58) and matched controls (n = 44) were recruited. Fasting blood samples were obtained for complete blood counts, basic metabolic panel, lipids, insulin, and Adipo. Ratios of platelets to HDL-C and Adipo were calculated. RESULTS Following adjustment for adiposity, only the platelet: HDL ratio was significantly increased in MetS and increased with severity of MetS. Receiver operating characteristic curve analysis showed that the platelet: HDL-C area under the curve (AUC) significantly added to both platelets and platelet lymphocyte ratio AUCs. Also the platelet: HDL-C ratio correlated with all cardio-metabolic features of MetS, high sensitivity C-reactive protein, insulin resistance chemerin, and leptin. CONCLUSIONS The ratio of platelets: HDL-C is significantly increased in patients with nascent MetS and appear to be a valid biomarker of MetS. It could also emerge as a biomarker for athero-thrombotic risk. However, these preliminary findings need confirmation in large prospective studies.

Abstract
This study aimed to investigate the association between mean platelet volume (MPV) and metabolic syndrome (MetS) in patients with type 2 diabetes mellitus (T2DM). Data for 1240 patients with T2DM admitted to the Department of Endocrinology at the First Affiliated Hospital of Guangxi Medical University between January 1, 2017 and June 1, 2020 were collected retrospectively via electronic medical records, including demographic information, complete blood count, lipid profile, and glucose metabolism indexes. MetS was defined according to the Chinese Diabetes Society. Among the 1240 patients enrolled, 873 (70.40%) had MetS. MPV was significantly higher in patients with MetS (P < .001). For individual MetS components, MPV was significantly higher in the presence of abdominal obesity (P = .013) and hypertriglyceridemia (P = .026), but did not differ in the presence of elevated blood pressure (P = .330) or low high-density lipoprotein cholesterol (P = .790). Moreover, MPV was independently associated with MetS after adjustment for sex, smoking, alcohol drinking, white blood cell count, fasting C-peptide, and body mass index (odds ratio 1.174, 95% confidence interval 1.059-1.302). The odds ratio for MetS in the highest tertile, compared with the lowest MPV tertile, was 1.724 (95% confidence interval 1.199-2.479, P for trend = .003) after multiple adjustment. In stratified analyses, the positive correlation of MPV with MetS was significant only in patients who were older, male, or overweight, or who had poor glycemic control. In conclusion, high MPV was positively associated with the presence of MetS in patients with T2DM, particularly older, male, or overweight patients, or those with poor glycemic control.

[PMID: 32645536 DOI: 10.1016/j.cyto.2020.155184] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 05/29/2020] [Accepted: 06/22/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND AND OBJECTIVE Patients with non-alcoholic fatty liver disease (NAFLD) have insulin resistance and are at an increased risk of diabetes. Recent evidence suggests that asprosin-a novel hormone secreted by white adipose tissue-may play a role in the pathogenesis of insulin resistance. However, the role of asprosin in NAFLD remains unclear. This study aimed to determine whether serum asprosin level could be used as a biochemical marker for NAFLD diagnosis. METHODS Forty-three untreated NAFLD patients and 50 sex- and age-matched healthy controls were included. Circulating serum asprosin and adiponectin (another adipokine) levels were detected by ELISA. Other metabolic parameters related to NAFLD were also determined. RESULTS Increased circulating serum asprosin and decreased serum adiponectin levels were found in NAFLD patients unlike in healthy controls. A positive correlation was observed between asprosin and platelet counts (PLT) (r = 0.3653, p = 0.015), fasting blood glucose (FBG) (r = 0.3592, p = 0.017), triglyceride (TG) levels (r = 0.3383, p = 0.025), serum albumin (ALB) levels (r = 0.3273, p = 0.030), and insulin resistance (HOMA-IR) (r = 0.4799, p = 0.001), whereas a negative correlation existed between adiponectin and TG levels in the NAFLD group. Multivariate linear regression showed that FBG and HOMA-IR were independently related to asprosin levels. Receiver operating characteristic (ROC) curves showed that asprosinAUC and adiponectinAUC were 0.735 (95%CI 0.633-0.836, P < 0.0001) and 0.702 (95%CI 0.597-0.807, p = 0.0007) respectively. Moreover, the combination of both biomarkers showed good sensitivity and specificity with AUC of 0.827, which was better than the single detection of asprosin or adiponectin. CONCLUSION High serum asprosin and low adiponectin level might be associated with the presence of insulin resistance in NAFLD, and the combination of asprosin and adiponectin could be a novel biomarker for diagnosing NAFLD. These data needed to be confirmed and extended in further large-population, well-designed clinical studies.

Abstract
PURPOSE We aimed to examine the associations of platelet parameters with the presence of metabolic syndrome in community-dwelling older Chinese adults. METHODS Study sample was from the Weitang Geriatric Diseases Study, which included 4338 individuals aged 60 years or above. The mean age of the participants was 68 years. Metabolic syndrome was defined based on the Adult Treatment Panel III criteria. Platelet parameters were assessed using an automated hematology analyzer. Multiple logistic regression models were fitted to examine relationships between the platelet parameters and the presence of metabolic syndrome after adjusting for potential confounders. RESULTS The adjusted odds ratio (95% CI) of metabolic syndrome for the highest quartile of platelet parameters (platelet count, mean platelet volume, plateletcrit, platelet distribution width, platelet larger cell ratio) when compared to the lowest quartile were 1.32 (1.06, 1.64), 1.00 (0.81, 1.24), 1.37 (1.10, 1.71), 1.45 (1.14, 1.83), 1.11 (0.89, 1.39), respectively. Hypertension and diabetes modified the relationship between platelet distribution width and metabolic syndrome with the associations being significant in hypertensive and non-diabetic groups. The levels of platelet distribution width increased with the risk of metabolic syndrome in men but not in women. CONCLUSION The levels of platelet count, plateletcrit and platelet distribution width increased in older adults with metabolic syndrome, suggesting that these parameters may be useful biomarkers for further risk appraisal of metabolic syndrome in aged population.

High Mean Platelet Volume Associates with In-Hospital Mortality in Severe Pneumonia Patients. Mediators Inflamm 2020; 2020:8720535. [PMID: 32587473 PMCID: PMC7298326 DOI: 10.1155/2020/8720535] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Revised: 05/01/2020] [Accepted: 05/13/2020] [Indexed: 01/20/2023] Open
Abstract
Background Although mean platelet volume (MPV) appears to be associated with poor outcome of pneumonia, the relationship between MPV and in-hospital mortality is unclear in severe pneumonia (SP) patients. Methods In this retrospective cohort study, 115 SP patients from June 1st, 2016, to September 29th, 2019, were included and divided into two groups. The primary outcome was in-hospital mortality. The receiver operating characteristic (ROC) curve was performed to assess the predictive ability for in-hospital mortality. Kaplan-Meier cumulative incidence curves were applied to observe the incidence of mortality. Multivariable Cox regression analyses were used to evaluate the hazard ratios (HRs). Besides, a formal test for interaction was investigated to analyze the relationship between MPV and sex. Results During the course of hospitalization, 63 cases of mortality were recorded. ROC analysis suggested that MPV had a modest power for predicting in-hospital mortality (AUC = 0.723, 95% CI: 0.628-0.818, P < 0.001). Yet the cutoff value of MPV was 10.5 (sensitivity = 73.02%; specificity = 73.08%). Compared to the low-MPV group, the high-MPV group had significantly increased in-hospital mortality (log-rank test = 13.501, P < 0.001), while the adjusted Cox model indicated that the high-MPV group was associated with an elevated risk of in-hospital mortality (HR: 2.267, 95% CI: 1.166-4.406, P = 0.016). Moreover, analyses of in-hospital mortality suggested a significant interaction between optimal MPV level and sex (P = 0.011). In a multivariate Cox model which included females only, a high MPV level was associated with increased risk of in-hospital mortality (HR: 11.387, 95% CI: 1.767-73.380, P = 0.011). Conclusion High MPV level is an independent risk factor for in-hospital mortality in patients with SP.

Abstract
Cardiovascular diseases (CVD) represent one of the biggest causes of death globally, and their prevalence, aetiology, and outcome are related to genetic, metabolic, and environmental factors, among which sex- and age-dependent differences may play a key role. Among CVD risk factors, platelet hyperactivity deserves particular mention, as it is involved in the pathophysiology of main cardiovascular events (including stroke, myocardial infarction, and peripheral vascular injury) and is closely related to sex/age differences. Several determinants (e.g., hormonal status and traditional cardiovascular risk factors), together with platelet-related factors (e.g., plasma membrane composition, receptor signaling, and platelet-derived microparticles) can elucidate sex-related disparity in platelet functionality and CVD onset and outcome, especially in relation to efficacy of current primary and secondary interventional strategies. Here, we examined the state of the art concerning sex differences in platelet biology and their relationship with specific cardiovascular events and responses to common antiplatelet therapies. Moreover, as healthy nutrition is widely recognized to play a key role in CVD, we also focused our attention on specific dietary components (especially polyunsaturated fatty acids and flavonoids) and patterns (such as Mediterranean diet), which also emerged to impact platelet functions in a sex-dependent manner. These results highlight that full understanding of gender-related differences will be useful for designing personalized strategies, in order to prevent and/or treat platelet-mediated vascular damage.

Abstract
BACKGROUND Metabolic syndrome (MetS) has been suggested to be a risk factor for many cancers, including breast cancer. However, it remains unclear whether MetS predicts poor prognosis in women with breast cancer. A meta-analysis was performed to summarize the association between MetS and clinical outcome in women with breast cancer. METHODS Cohort studies were identified by search of PubMed and Embase databases. A random-effect model incorporating the potential heterogeneity was applied to pool the results. Subgroup analyses according to the ethnicity and study design were performed. RESULTS Nine cohort studies with 17,892 women with breast cancer were included. Pooled results showed that MetS was significantly associated with an increased risk of breast cancer recurrence (adjusted risk ratio [RR] = 1.52, 95%, p = 0.02). Subgroup analyses showed that MetS was independently associated with increased recurrence of breast cancer in Caucasians (adjusted RR = 1.75, p = 0.02), but not in Asians (adjusted RR = 1.07, p = 0.81), and MetS was associated with a trend of increased risk of breast cancer recurrence in both the prospective and retrospective studies. Although we failed to show a significant association between MetS and breast cancer related deaths (adjusted RR = 1.24, p = 0.41), MetS was associated with increased risk of all-cause deaths in these patients (adjusted RR = 1.80, p < 0.001). CONCLUSIONS MetS may predict the risk of cancer recurrence and mortality in women with breast cancer, particularly in Caucasians.

Abstract
Platelet size has been demonstrated to reflect platelet activity and seems to be a useful predictive and prognostic biomarker of cardiovascular events. It is associated with a variety of prothrombotic and proinflammatory diseases. The aim is a review of literature reports concerning changes in the mean platelet volume (MPV) and its possible role as a biomarker in inflammatory processes and neoplastic diseases. PubMed database was searched for sources using the following keywords: platelet activation, platelet count, mean platelet volume and: inflammation, cancer/tumor, cardiovascular diseases, myocardial infarction, diabetes, lupus disease, rheumatoid arthritis, tuberculosis, ulcerative colitis, renal disease, pulmonary disease, influencing factors, age, gender, genetic factors, oral contraceptives, smoking, lifestyle, methods, standardization, and hematological analyzer. Preference was given to the sources which were published within the past 20 years. Increased MPV was observed in cardiovascular diseases, cerebral stroke, respiratory diseases, chronic renal failure, intestine diseases, rheumatoid diseases, diabetes, and various cancers. Decreased MPV was noted in tuberculosis during disease exacerbation, ulcerative colitis, SLE in adult, and different neoplastic diseases. The study of MPV can provide important information on the course and prognosis in many inflammatory conditions. Therefore, from the clinical point of view, it would be interesting to establish an MPV cut-off value indicating the intensity of inflammatory process, presence of the disease, increased risk of disease development, increased risk of thrombotic complications, increased risk of death, and patient's response on applied treatment. Nevertheless, this aspect of MPV evaluation allowing its use in clinical practice is limited and requires further studies.

Abstract
Introduction The role of whole blood count parameters in the diagnosis of diseases in which inflammatory processes play a role is one of the more frequently mentioned topics in the literature in recent years. Studies of acute appendicitis have also been carried out in this regard, but studies focused on platelet parameters are few and contradictory. We aimed to investigate the role of mean platelet volume (MPV) and platelet distribution width (PDW) in the diagnosis of acute appendicitis. Materials and methods We retrospectively screened the medical records of patients older than 15 years who had an appendectomy from January 2012 to January 2015 at a training hospital in Kocaeli, Turkey. Patients were divided into three groups according to their pathology results: non-appendicitis (Group 1), uncomplicated appendicitis (Group 2), and complicated appendicitis (Group 3). We calculated the sensitivity, specificity, positive and negative predictive values, the likelihood ratios in the diagnosis of appendicitis for white blood cell (WBC), neutrophil count, c-reactive protein (CRP), MPV, and PDW values were calculated. Results There were no significant differences in the MPV between Group 1 (n = 39; 7.89 ± 1.32 fL), Group 2 (n = 119; 7.80 ± 1.19 fL), and Group 3 (n = 89; 7.70 ± 0.80 fL; p = 0.141). Also, we found no significant differences in PDW between Group 1 (117.38% ± 1.17), Group 2 (17.17% ± 1.04), and Group 3 (17.12% ± 0.64; p = 0.228). Conclusions Only nine of the 208 patients whose pathology reports confirmed appendicitis had healthy values for both CRP and WBC. Many factors affect MPV and PDW. Therefore, platelet indices are not useful markers in diagnosing acute appendicitis.

Abstract
AIMS The current study aimed to explore the correlation between leukocytes and platelets indices with adipocytokines (leptin and adiponectin) and MetS components. METHODS A total of 100 healthy subjects and 200 patients diagnosed with different MetS components were enrolled in the study. Eligible patients were allocated into four groups (50 patients). Group1 include patients with 2 criteria of MetS components, group 2 with 3 criteria, group 3 with 4 criteria and group 4 had patients with 5 criteria. RESULTS Regarding white blood cell indices, data showed that total leukocyte and neutrophil count as well as neutrophil/lymphocyte (N/L) ratio were significantly increased in all groups of MetS patients when compared to the healthy group. Additionally, platelets count, platelet distribution width (PDW), and main platelet volume (MPV) levels and platelets/lymphocyte (P/L) ratio were significantly higher in all patients with MetS as compared to the healthy subjects. Serum leptin concentration and leptin-to-adiponectin ratio (LAR) were elevated significantly, while adiponectin level was significantly diminished in all MetS groups when compared to the control. CONCLUSION leukocytes and platelets indices were associated with hyperleptinemia and hypoadiponectinemia as well as MetS components. The study also suggested the necessary role of leukocytes, platelet indices, and LAR as markers in early diagnoses of individuals with MetS components.

Abstract
Mean platelet volume (MPV) is a determinant of activation and variability of platelets (PLT). The focus of this study was to to investigate MPV values in patients with and without metabolic syndrome (MS). It also evaluates the association between them. There are close connections among MPV, MS, and cardiometabolic risk. We compiled age, body mass index, blood cell counts, MPV, and other data of 59976 self-reported healthy volunteers (28428 male, 31548 female), 24.65% of who have MS. The mean age of the group was 48.21 years old. The data was grouped by sex and values of data between men and women groups were analyzed by independent sample’s t-test. The relationship between sex and MS was evaluated by chi-square tests. Crude odd ratios of MS between MPV quartiles and 95% confidence intervals were analyzed by binary logistic regression in this study. We found women had higher levels of MPV (10.09 vs. 9.98, P < 0.01) and PLT (228.68 vs. 212.11, P < 0.01) than men. In females, the prevalence of MS was higher in low MPV group than in high MPV groups. The odds of having MS were significantly lower in higher MPV quartiles compared with MPV Quartile 1 in women (Adjusted OR < 1, P < 0.01). This study indicated that MS was inversely associated with MPV in females only.

Abstract
AIMS Some studies have demonstrated that metabolic syndrome is associated with hematological parameters. The present study explores the relationship between hematological parameters and numbers of metabolic syndrome conditions in Iranian men. METHODS This cross-sectional study included 11,114 participants who were professional drivers of commercial motor vehicles, and were enrolled in the Iranian Health Surveys between 2014 and 2016. Diagnosis of metabolic syndrome was made according to International Diabetes Federation criteria. Clinical data, including anthropometric measurements and serum parameters, were collected. Odds ratios for hematological parameters and metabolic syndrome were calculated using binary logistic regression models. RESULTS We found that hemoglobin; platelet, and white blood cell counts increased with increasing numbers of metabolic syndrome components (p<0.05 for all). The odds ratio of metabolic syndrome significantly increased across successive quartiles of platelet (1.00, 1.25, 1.29, and 1.51) and white blood cell counts (1.00, 1.51, 1.79, and 2.11) with the lowest quartile as the referent group. Similar associations for hemoglobin and hematocrit in the top quartile were also observed. We did not observe any significant difference in the mean of neutrophil count, mean platelet volume (MPV), red cell distribution width, or platelet distribution width among participants with or without metabolic syndrome. CONCLUSIONS Our findings indicate that high levels of major hematological parameters such as hemoglobin, hematocrit, as well as platelet and white blood cell counts could be novel indicators for the development of metabolic syndrome.

Platelet mass index is increased in psoriasis. A possible link between psoriasis and atherosclerosis. ARCHIVES OF MEDICAL SCIENCES. ATHEROSCLEROTIC DISEASES 2017; 1:e145-e149. [PMID: 28905037 PMCID: PMC5421536 DOI: 10.5114/amsad.2016.64444] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/03/2016] [Accepted: 11/28/2016] [Indexed: 11/17/2022]
Abstract
INTRODUCTION Psoriasis, whose relation with atherosclerosis etc. has long been known, is a chronic inflammatory disease. Besides providing hemostasis, platelets play important roles in inflammatory reactions and immune responses and contribute to endothelial damage, thus leading to atherosclerotic plaque formation. Mean platelet volume (MPV) has been previously reported as a platelet activation marker. Platelet mass index (PMI) is also related to platelet functionality and is thought to be a useful parameter for plaque formation capacity of platelets. MATERIAL AND METHODS Sex, age, age of onset, disease duration, family history, psoriasis area severity index, nail and joint involvement, platelet count, mean platelet volume, platelet mass index, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) of 320 patients with psoriasis and 200 healthy persons were evaluated. RESULTS Mean platelet counts were 277.7 ±73.374 and 265.06 ±59.682 (p = 0.032); MPV values were 8.248 ±1.150 and 7.442 ±1.626 (p < 0.001); and PMI values were 2259 ±545.617 and 1964 ±622.762 (p < 0.001) respectively in the psoriasis and control group. The MPV showed a significant but inverse correlation with hs-CRP (p = 0.047, r = -0.149), and no correlation with ESR (p > 0.05). Platelet count and PMI had a significant and positive correlation with ESR (p < 0.001, r = 0.404 and p < 0.001, r = 0.371), but had no correlation with hs-CRP (p > 0.05). CONCLUSIONS Higher PMI and MPV values, which mean higher plaque formation capacity and more active platelets, in psoriasis may make psoriasis patients more sensitive to atherosclerotic plaque formation and complications. On the other hand, because of the positive PMI correlation with ESR (MPV had no correlation with ESR and had a negative correlation with CRP), PMI may be a better predictor of inflammation than MPV in psoriasis.

Abstract
Leukocyte, erythrocyte or platelet and metabolic syndrome (MS) are closely correlated, and there exist gender differences. We aimed to explore the associations between the hematological parameters and MS in different genders of Chinese. This cross-sectional study included 32,900 participants (20,733 males, 12,167 females) who were enrolled in a health examination. Clinical data including anthropometric measurements and serum parameters were collected. The associations between hematological parameters and MS of both genders were analyzed separately. Odds ratio (OR) of MS was calculated by binary logistic regression models. All hematological parameters were related to MS. With leukocyte and erythrocyte counts rising, the risks of developing MS increased in both genders, which was more obvious in women. For instance, in model 3, the ORs of MS in leukocyte quartiles in females were from 1.333 to 2.045 (P < 0.01), while in males, from 1.238 to 1.675 (P < 0.01). Platelet seemed as a protective factor in males. Model 1 and model 3 in quartile 2 demonstrated ORs of 0.922 (P < 0.05) and 0.912 (P < 0.05). However, platelet acted as risk factor in female. For instance, the ORs were 1.253 (P < 0.01), 1.461 (P < 0.01), and 1.322 (P < 0.01) in platelet quartile 4 of all 3 models in female. Gender has influences on the associations between leukocyte, erythrocyte or platelet, and MS. In both genders, higher levels of leukocyte and erythrocyte increased risks of MS. For men, platelet was a protective factor, but for women, platelet seemed as a risk factor.

Abstract
Mean platelet volume (MPV) and platelet distribution width (PDW) are morphometric indices of size distribution and variability of platelet. We aimed to explore the associations between MPV or PDW and thyroid function in a large Chinese cohort.This was a cross-sectional study with a recruitment of 13,622 self-reported healthy Chinese (8424 males, 5198 females). Clinical data of the participants comprised of anthropometric measurements, hepatic function, renal function, serum levels of lipid, glucose, C-reactive protein, erythrocyte sedimentation rate, platelet, MPV, PDW, and thyroid hormones. Database was sorted by sex, and the associations between MPV or PDW and thyroid function were analyzed by quartiles of MPV or PDW. Levels of MPV and PDW were compared in different thyroid function subgroups by 1-way analysis of variance and independent sample's t test. Receiver-operating characteristic (ROC) curve was adopted to determine diagnostic values of MPV and PDW for thyroid dysfunction. Crude and adjusted odds ratios of MPV and PDW for thyroid dysfunction with 95% confidence intervals were analyzed by binary logistic regression models.MPV, PDW, and thyroid stimulation hormone were significantly higher in females than in males. Females showed significantly higher incidence of hypothyroidism and hyperthyroidism than males. However, there were no significant differences of MPV and PDW among different thyroid function subgroups in both sexes, and no obvious correlations were revealed between MPV or PDW and thyroid function. From ROC analysis, we demonstrated no diagnostic values of MPV and PDW for thyroid dysfunction. From binary logistic regression models, no risks of different MPV and PDW quartiles were identified for thyroid dysfunction in both sexes.We could not show any association between MPV or PDW and thyroid function. Prospective studies with better defined risk groups should be performed in the future for further verification and validation.

Abstract
[Purpose] Osteoporosis is an inflammatory disease, and platelets play a critical role in bone remodeling. Mean platelet volume has been shown to be influenced by inflammation. Our aim was to evaluate the relationship between mean platelet volume and bone mineral density in postmenopausal women. [Subjects and Methods] The records of female patients who had been referred to a tertiary hospital for bone mineral density analysis were retrospectively reviewed. [Results] A total of 175 patients (mean age: 61.3 ± 9.0 years) were enrolled. Overall, 72% (126/175) of patients met the criteria for osteoporosis. Mean platelet volume was found to be inversely correlated with body mass index. There was a significant positive correlation between mean platelet volume and femoral neck bone mineral density in our normal weight osteoporotic group, whereas there was a significant negative correlation in our overweight-obese osteoporotic group. The negative correlation between mean platelet volume and femoral neck bone mineral density in the overweight-obese osteoporotic group persisted after adjustment for confounding factors. Multivariate analyses revealed that mean platelet volume was significantly associated with femoral neck bone mineral density in osteoporotic patients in both our normal weight and overweight-obese groups. [Conclusion] Regardless of mechanisms, mean platelet volume might be used as a biomarker for osteoporosis in clinical settings.

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
Hypoxia is a prominent characteristic of inflammatory tissue lesions. It can affect platelet function. While mean platelet volume (MPV) and platelet distribution width (PDW) are sample platelet indices, they may reflect subcinical platelet activation. To investigated associations between adiposity indices and platelet indices, 17327 eligible individuals (7677 males and 9650 females) from the Dongfeng-Tongji Cohort Study (DFTJ-Cohort Study, n=27009) were included in this study, except for 9682 individuals with missing data on demographical, lifestyle, physical indicators and diseases relative to PDW and MPV. Associations between adiposity indices including waist circumstance (WC), waist-to-height ratio (WHtR), body mass index (BMI), and MPV or PDW in the participants were analyzed using multiple logistic regressions. There were significantly negative associations between abnormal PDW and WC or WHtR for both sexes (ptrend<0.001 for all), as well as abnormal MPV and WC or WHtR among female participants (ptrend<0.05 for all). In the highest BMI groups, only females with low MPV or PDW were at greater risk for having low MPV (OR=1.33, 95% CI=1.10, 1.62 ptrend<0.001) or PDW (OR=1.34, 95% CI=1.14, 1.58, ptrend<0.001) than those who had low MPV or PDW in the corresponding lowest BMI group. The change of PDW seems more sensitive than MPV to oxidative stress and hypoxia. Associations between reduced PDW and MPV values and WC, WHtR and BMI values in Chinese female adults may help us to further investigate early changes in human body.

Abstract
PURPOSE The heterogeneity of serious emotional disturbance has been thoroughly documented among adolescents with nationally representative data derived from structured interviews, although use of these interviews may not be feasible within the context of brief and self-administered school surveys. This study seeks to identify distinct subtypes of serious emotional disturbance in a large school-based sample. METHODS A total of 108,736 students fully completed the K6 scale that was included on the 2012 Kentucky Incentives for Prevention Survey. Latent class analysis was used to derive subtypes of serious emotional disturbance among students receiving a positive screen (n = 15,147). To determine significant predictors of class membership, adjusted rate ratios and 95 % confidence intervals were calculated using multinomial logistic regression. RESULTS A four-class model was the most parsimonious, with four distinct subtypes emerging that varied by both symptom type and severity: comorbid moderate severity, comorbid high severity, anxious moderate severity, and depressed high severity. Age, gender, race/ethnicity, family structure, substance use, antisocial behavior, role impairments, and peer victimization were significant predictors of class membership, although the magnitude of these effects was stronger for the two high severity groups. CONCLUSIONS Our results suggest heterogeneity of serious emotional disturbance by both symptom type and severity. Prevention programs may benefit by shifting focus from specific disorders to the core features of serious emotional disturbance, including psychological distress, high comorbidity, and role impairments.

Abstract
Obstructive sleep apnea syndrome (OSAS) is a common disorder that can lead to significant cardiovascular complications. Several studies have reported increased platelet activation and aggregation in patients with OSAS. In this study we aimed to show a correlation between mean platelet volume (MPV) and severity of OSAS in patients with OSAS without any overt cardiac disease or diabetes. The polysomnography recordings of 556 consecutive patients admitted to the sleep laboratory between January 2012 and July 2012 were retrospectively evaluated. The relationship between polysomnographic parameters and biochemical parameters was assessed. Polysomnographic results of 200 patients (154 males [77%]; mean age, 44.5 ± 11.4 years) were included. No correlation was observed between MPV and the average oxygen saturation index, the minimum desaturation index, or the oxygen desaturation index in the study population as well as in severe OSAS group (AHI > 30). The only correlation was found between MPV and AHI in the severe OSAS group (P = 0.010). MPV was not correlated with OSAS severity in patients without any overt cardiac disease or diabetes. These findings raise doubts about the suggestion that MPV might be a marker for OSAS severity, as recommended in earlier studies. Thus, further prospective data are needed.

Abstract
AIM Recent studies have shown that platelet indices are linked to metabolic and cardiovascular diseases, in addition to being markers of hemostasis. These studies suggested that they could be modified by various biomolecules, including lipids. Proprotein convertase subtilisin/kexin type 9 (PCSK9), a newly-identified member, plays a key role in lipid metabolism and atherosclerosis. Therefore, we evaluated the relationship between the plasma PCSK9 level and platelet indices. METHODS In this cross-sectional study, a total of 330 consecutive, stable coronary artery disease (CAD) patients were enrolled at our center between October 2012 and April 2014. The baseline clinical characteristics were collected, and the plasma PCSK9 levels were determined using an ELISA. The associations between PCSK9 and the platelet indices were investigated. RESULTS The plasma PCSK9 levels were positively correlated with the platelet (PLT) count and plateletcrit (PCT) (r = 0.218, p < 0.001; r = 0.250, p < 0.001; respectively), while no correlation of PCSK9 with either the mean platelet volume (MPV) or platelet distribution width (PDW) was found. The association of PCSK9 with the PLT and PCT remained after adjusting for cardiometabolic risk factors (β=0.300, p < 0.001; β = 0.269, p < 0.01; respectively), but the latter disappeared when further adjusted for inflammatory markers (β = 0.212, p < 0.05; β = 0.151, p = NS). Additionally, a correlation analysis performed according to the number of diseased vessels showed that PCSK9 was related to the PLT and PCT in patients with single-, two- or multi-vessel disease, with a particularly strong correlation with two-vessel disease. CONCLUSIONS The plasma PCSK9 levels are positively associated with the PLT count in CAD patients, suggesting a potential link between PCSK9 and platelets that may be involved in atherosclerosis and metabolic disorders.

Abstract
The purposes of the study were to estimate the incidence of metabolic syndrome (MetS) and to systematically evaluate the relationship between hematological parameters and MetS in a 5-year follow-up of Beijing adult population. The longitudinal study included 3,180 adults, aged 20-65 years, who attended health check-ups in Beijing Tongren Hospital in 2007 and 2012. Multivariate logistic regression was conducted to explore the associations between hematological parameters and MetS. The 5-year cumulative incidence of MetS in this sample was 10.82 % (14.22 % for males and 7.59 % for females). Among all the hematological parameters, white blood cell count (WBC) was positively associated with MetS for 20-35-year-old (male OR 1.482, 95 % CI 1.169-2.974; female OR 1.398, 95 % CI 1.145-3.011), and 36-50-year-old (male OR 2.012, 95 % CI 1.290-4.010; female OR 3.400, 95 % CI 1.818-4.528) male and female subjects. Alanine aminotransferase (ALT) was significantly associated with the incidence of MetS for males (20-35-year-old OR 2.080, 95 % CI 1.371-3.159; 36-50-year-old OR 2.421, 95 % CI 1.335-3.412; 51-65-year-old OR 4.267, 95 % CI 1.161-6.781). Low-density lipoprotein cholesterol (LDL-C) was positively associated with MetS for 51-65-year-old (male OR 3.078, 95 % CI 2.468-5.131; female OR 2.140, 95 % CI 1.524-4.359) for male and female subjects. WBC is positively associated with MetS for young adults, while LDL-C is positively associated with MetS for elderly people. ALT is positively associated with MetS for males. Our findings provide further evidence in support of using hematological markers for early detection of individuals at risk for MetS.

Abstract
Platelet count (PC) has been found to be related to the metabolic syndrome (MetS). However, the role of PC on MetS remained unclear. In order to evaluate the relationship between PC and MetS components cross-sectionally and determine the optimal cutoff PCs for predicting the subsequent risk of MetS development with sex specificity, two stages included cross-sectional (stage 1) and prospective (stage 2) cohort study were conducted. Stage 1 involved 10 579 subjects aged ≥60 years, of which 7718 subjects advanced to stage 2 with a mean 3.8 year follow-up were enrolled. The MetS components and PC were determined. The PC cutoffs for higher chances of developing MetS in stage 1 were calculated using receiver operating characteristic (ROC) curve analyses. In stage 2, non-MetS subjects were classified into high-PC (HPC) and low-PC (LPC) groups according to the cutoff values from stage 1. We examined the difference of future MetS incidence and calculated the odds ratio (OR) between these two groups. In stage 1, multiple regression showed that age and triglyceride (both sexes) and waist circumstance and high-density lipoprotein cholesterol (only women) were independently correlated with PC. There was significant difference in the area under the ROC curve (AUC) only of HPC women, which exceeded the standard curve (AUC = 0.542, p < 0.001), with a cutoff PC of 223 × 10(3)/μl. HPC women had an OR of 1.287 (95% confidence interval: 1.135-1.461) of developing MetS after 3.8 years. The Kaplan-Meier curve demonstrated a higher incidence of MetS development in HPC women. In conclusion, our results suggest that PC was associated with MetS with sex effects. Most of the MetS components were independent factors for increasing PC, and the risk for subsequent development of MetS was noted when PC >223 × 10(3)/μl in elderly women.

Abstract
Objectives: Alteration in platelet morphology and functions are associated with pathological processes and increased risk of vascular complications in patients with diabetes. The purpose of the study was to find the correlation between platelet indices with fasting blood glucose, HbA1c and hs-CRP level in pathogenesis of vascular complications in type 2 diabetic patients. Methodology: The study has been carried out on 51 Type 2 Diabetics and 55 age and sex matched healthy control subjects. Fasting blood glucose (FBG), Glycosylated hemoglobin (HbA1c), high sensitivity C- reactive protein (hs-CRP) level and platelet indices including Platelet count (PLT), Plateletcrit (PCT), Mean platelet volume (MPV), Platelet distribution width (PDW) were estimated and compared with normal subjects. The results were evaluated statistically. Results: The study demonstrated that FBG, HbA1c, MPV, PDW and hs-CRP were statistically higher in diabetics in comparison with control subjects (P is less than 0.05). Positive correlation of FBG with HbA1c (r is equal to 0.993, P is equal to 0.0001), PLT with PCT (r is equal to 0.922, P is equal to 0.0001) and MPV with PDW (r is equal to 0.332, P is equal to 0.024) was found in diabetics. Conclusion: The poor glycemic control is positively correlated with high HbA1c level. The increased values of MPV, PDW and elevated hs-CRP level may also serve as confirmatory test in finding risk of developing complications.

Abstract
Atherothrombotic complications are important causes of morbidity and mortality in diabetic patients. Diabetes has been considered to be a prothrombotic status. Several factors contribute to the prothrombotic condition, such as increasing coagulation, impaired fibrinolysis, endothelial dysfunction, and platelet hyperreactivity. Among the factors that contribute to the prothrombotic status in diabetes, altered platelet function plays a crucial role. Although understanding platelet function abnormalities in diabetes still remains as a challenge, more attention should be focused on platelet function for effective management and the prediction of atherothrombotic events in diabetic patients. This review will provide an overview on the current status of knowledge of platelet function abnormalities and clinical marker of platelet hyperreactivity in patients with diabetes.

Abstract
Interest in childhood metabolic syndrome (MetS) has increased substantially due to the increasing prevalence of childhood obesity on a global scale. Early recognition of MetS is critical in order to delay the development of cardiovascular disease (CVD). In this study, we evaluated the relationship between complete blood count (CBC) parameters and MetS among pre-pubertal children which may provide evidence in support of using low cost, readily available clinical haematological parameters for the detection of MetS. A retrospective analysis was carried out on 330 (125 lean vs. 205 overweight) Turkish pre-pubertal children who attend to a paediatric outpatient clinic. Age, gender, puberty, body mass index, CBC parameters, cardiometabolic risk factors including lipid profiles, high sensitive serum reactive protein (hsCRP) and insulin resistance index calculated by homeostasis model assessment (HOMA-IR) were evaluated and compared among lean, overweight children and children with MetS. The mean age of the study population was 7.4 ± 1.9 years. In both gender, the mean values of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were significantly lower and red blood cell (RBC), platelet (PLT) counts were significantly higher in overweight children. Overall, 8.4% (n = 28) of patients met the criteria of MetS. Children with MetS had higher levels of PLT and lower levels of mean platelet volume (MPV). Of all the haematological parameters analysed, PLT was positively, whereas MPV was negatively correlated with MetS in girls. In addition, MPV was inversely correlated with fasting blood glucose, HOMA-IR, low density lipoprotein-cholesterol (LDL-C) and low density lipoprotein-cholesterol/high density lipoprotein-cholesterol (LDL-C/HDL-C) ratio in girls after adjusting for confounding factors. The risk analyses of MetS in terms of MPV quartiles showed that the adjusted OR (95% CI) for the lowest vs. the highest quartile was 7.71 (1.45-40.89) in girls. These data might suggest that MPV could be another feature of MetS in pre-pubertal girls and might be used as a surrogate marker for MetS in clinical settings.

Abstract
The protective effect of increased levels of indirect bilirubin on atherosclerotic heart disease in patients of Gilbert's syndrome is well known. The aim of the study was to investigate the effects of increased levels of bilirubin on the mean platelet volume (MPV) and other hematological parameters. Thirty-two men and 36 women (a total of 68 Gilbert's syndrome patients) and a similar age group of 68 healthy individuals (32 men and 36 women) were included in the study. Hematologic tests, C-reactive protein (CRP) and biochemical values of the two groups were checked. MPV level of Gilbert's syndrome group was 7.8±1.0fl and CRP 0.2±0.27mg/dl. In the control group MPV was 8.6±1.0fl and CRP 0.3±0.38mg/dl. MPV of patients group (P<0.001) and CRP (P=0.037) were significantly lower than the control group. When dividing Gilbert's syndrome and control groups according to sex into subgroups the level of indirect bilirubin in men with Gilbert's syndrome (1.8±0.8mg/dl) was found to be higher than other groups. Healthy men had higher levels of MPV (8.8±0.9fl) whereas Gilbert's syndrome male patients had lower levels (7.7±1.1fl), (P<0.001). The elevated levels of bilirubin and decreasing levels of MPV and CRP in Gilbert's syndrome patients may have an effect on the slowing down of the atherosclerotic process.

Abstract
Cardiovascular disease is the foremost cause of morbidity and mortality in the Western world. Atherosclerosis followed by thrombosis (atherothrombosis) is the pathological process underlying most myocardial, cerebral, and peripheral vascular events. Atherothrombosis is a complex and heterogeneous inflammatory process that involves interactions between many cell types (including vascular smooth muscle cells, endothelial cells, macrophages, and platelets) and processes (including migration, proliferation, and activation). Despite a wealth of knowledge from many recent studies using knockout mouse and human genetic studies (GWAS and candidate approach) identifying genes and proteins directly involved in these processes, traditional cardiovascular risk factors (hyperlipidemia, hypertension, smoking, diabetes mellitus, sex, and age) remain the most useful predictor of disease. Eicosanoids (20 carbon polyunsaturated fatty acid derivatives of arachidonic acid and other essential fatty acids) are emerging as important regulators of cardiovascular disease processes. Drugs indirectly modulating these signals, including COX-1/COX-2 inhibitors, have proven to play major roles in the atherothrombotic process. However, the complexity of their roles and regulation by opposing eicosanoid signaling, have contributed to the lack of therapies directed at the eicosanoid receptors themselves. This is likely to change, as our understanding of the structure, signaling, and function of the eicosanoid receptors improves. Indeed, a major advance is emerging from the characterization of dysfunctional naturally occurring mutations of the eicosanoid receptors. In light of the proven and continuing importance of risk factors, we have elected to focus on the relationship between eicosanoids and cardiovascular risk factors.
