REVIEW
Deepti Sharma, Garima Singh
Thrombocytosis has been suggested to be a poor prognostic indicator in malignancies. Studies have shown that thrombocytosis is associated with a poor prognosis in various gynecological malignancies such as carcinoma ovary, cervical cancer, and endometrial cancer. The aim of this study is to analyze the impact of thrombocytosis on the prognosis of gynecological cancer. All the relevant data were retrieved by PubMed, MEDLINE, and Web of Science, and then studies were chosen in this analysis of association between thrombocytosis and gynecological malignancy...

BACKGROUND: The death toll associated with inhaled ambient particulate matter (PM) is attributed mainly to cardio-vascular rather than pulmonary effects. However, it is unclear whether the key event for cardiovascular impairment is particle translocation from lung to circulation (direct effect) or indirect effects due to pulmonary particle-cell interactions. In this work, we addressed this issue by exposing healthy mice via inhalation and intra-arterial infusion (IAI) to carbon nanoparticles (CNP) as surrogate for soot, a major constituent of (ultrafine) urban PM...

The mortality caused by sepsis is high following thermal injury. Diagnosis is difficult due to the ongoing systemic inflammatory response. Previous studies suggest that cellular parameters may show promise as diagnostic markers of sepsis. The aim of this study was to evaluate the effect of thermal injury on novel haematological parameters and to study their association with clinical outcomes. Haematological analysis was performed using a Sysmex XN-1000 analyser on blood samples acquired on the day of the thermal injury to 12 months post-injury in 39 patients (15-95% TBSA)...

The purpose of the present retrospective study was to investigate whether a score reflecting systemic inflammatory processes [the Glasgow Prognostic Score (GPS)] provides relevant information for radiation oncologists. GPS is a three-tiered score [0: normal C-reactive protein (CRP) and albumin; 1: one abnormal result; 2: increased CRP and low albumin]. Correlations between disease type and extent, resource utilization, survival and GPS were analyzed in 703 patients. In the subgroup with GPS 2, significantly higher rates of lung, adrenal gland and liver metastases were observed...

Previous studies have linked the presence of thrombocytosis with the progression and development of cancer; however, this trend requires further investigation. The present study aimed to derive an estimation of the degree of association between thrombocytosis and the 5-year overall survival rate of patients with cancer, as well as common clinicopathological features, by performing a meta-analysis of 20 (n=12,778) published studies. The PubMed and Embase databases were searched systematically for all relevant articles published in English...

BACKGROUND: Currently, stratification of patients with bladder cancer (BC) mainly relies on histopathologic and clinical staging. Furthermore, inflammation plays an important role in the pathogenesis of BC. With the preoperative platelet-to-leukocyte ratio (PLR), we introduce a novel prognostic marker based on routine hematologic values in patients undergoing radical cystectomy (RC). PATIENTS AND METHODS: In our cohort of 665 patients undergoing RC (2004-2015) for urothelial carcinoma of the bladder (UCB), we analyzed a variety of preoperative hematologic parameters...

Essential thrombocythemia (ET) is a myeloproliferative neoplasm that occurs mostly in patients above the age of 50 years. Its incidence in children is very rare, with around 100 cases reported in the literature. High-risk patients are defined by previous life threatening major thrombotic or severe hemorrhagic complication or age > 60. Those patients probably benefit from cytoreductive therapy. On the other hand, antiplatelet drugs are recommended for patients with low risk group. Although rare, ET should be considered in the differential diagnosis of persistent thrombocytosis in children, even at a very young age...

PURPOSE OF REVIEW: This article reviews the spectrum of neurologic complications associated with lymphoma, leukemia, and paraproteinemic disorders. While leptomeningeal metastasis is the most common complication of lymphoma and leukemia and peripheral neuropathy is the most common complication of paraproteinemic disorders, clinicians need to be familiar with the diverse neurologic complications of these disorders. RECENT FINDINGS: Lymphomatous nervous system involvement can be difficult to diagnose, especially when it is the presenting symptom...

AIM: To determine the true prevalence of thrombocytosis in children less than 2 years of age with bronchiolitis, its association with risk factors, disease severity and thromboembolic complications. METHODS: A retrospective observational medical chart review of 305 infants aged two years or less hospitalized for bronchiolitis. Clinical outcomes included disease severity, duration of hospital stay, admission to pediatric intensive care unit, or death. They also included complications of thrombocytosis, including thromboembolic complications such as cerebrovascular accident, acute coronary syndrome, deep venous thrombosis, pulmonary embolus, mesenteric thrombosis and arterial thrombosis and also hemorrhagic complications such as bleeding (spontaneous hemorrhage in the skin, mucous membranes, gastrointestinal, respiratory, or genitourinary tracts)...

Essential thrombocytosis (ET) is a rare disease with known thrombotic and bleeding complications. We encountered a patient with a diagnosis of longstanding Janus kinase-2 gene-negative ET on aspirin therapy presenting for labor epidural. Evaluation of platelet function with pointof-care analysis using Plateletworks in a community hospital setting allowed confirmation of adequate numbers of functional platelets to support safe epidural placement. The relevant issues of ET for anesthesia management with labor epidurals are discussed...

Diabetes mellitus is associated with an increased risk for cardiovascular disease, but the link between hyperglycemia and atherothrombotic disease is not completely understood. Patients with diabetes often show hyporesponsiveness to antiplatelet therapies, and it has been suggested that hyperreactive reticulated platelets underlie this altered therapeutic response. In this issue of the JCI, Kraakman et al. uncover a previously unknown link between hyperglycemia and enhanced platelet production and reactivity...

Platelets play a critical role in atherogenesis and thrombosis-mediated myocardial ischemia, processes that are accelerated in diabetes. Whether hyperglycemia promotes platelet production and whether enhanced platelet production contributes to enhanced atherothrombosis remains unknown. Here we found that in response to hyperglycemia, neutrophil-derived S100 calcium-binding proteins A8/A9 (S100A8/A9) interact with the receptor for advanced glycation end products (RAGE) on hepatic Kupffer cells, resulting in increased production of IL-6, a pleiotropic cytokine that is implicated in inflammatory thrombocytosis...

Essential thrombocythemia (ET) is a chronic myeloproliferative neoplasm that is associated with diminished quality of life, thrombohemorrhagic complications, and transformation to myelofibrosis (MF) and acute leukemia (AML). The important recent discoveries of driver mutations, including the calreticulin gene in addition to JAK2 and MPL, have led to a greater understanding of disease pathogenesis and set the stage for the advent of more sophisticated prognostic, diagnostic, and therapeutic strategies. In this paper we summarize recent studies describing the molecular basis of ET...

REVIEW
Akihide Yoshimi, Omar Abdel-Wahab
Spliceosomal mutations, especially mutations in SF3B1, are frequently (>80%) identified in patients with refractory anemia with ringed sideroblasts (RARS) and myelodysplastic/myeloproliferative neoplasms with ringed sideroblasts and thrombocytosis (MDS/MPN-RS-T; previously known as RARS-T), and SF3B1 mutations have a high positive predictive value for disease phenotype with ringed sideroblasts. These observations suggest that SF3B1 mutations play important roles in the pathogenesis of these disorders and formation of ringed sideroblasts...

The thrombopoietin (TPO) gene expression in human ovary and cancer cells from patients with ovarian carcinomatosis, as well as several cancer cell lines including MDA-MB231 (breast cancer), K562 and HL60 (Leukemic cells), OVCAR-3NIH and SKOV-3 (ovarian cancer), was performed using RT PCR, real-time PCR, and gene sequencing. Human liver tissues are used as controls. The presence of TPO in the cells and its regulation by activated protein C were explored by flow cytometry. TPO content of cell extract as well as plasma of a patient with ovarian cancer was evaluated by ELISA...
