High frequency of non classical steroid 21-hydroxylase deficiency

AB - Increased mobilization of circulating endothelial progenitor cells may represent a new biological hallmark of myeloproliferative neoplasms. We measured circulating endothelial colony forming cells (ECFCs) in 106 patients with primary myelofibrosis, fibrotic stage, 49 with prefibrotic myelofibrosis, 59 with essential thrombocythemia or polycythemia vera, and 43 normal controls. Levels of ECFC frequency for patient's characteristics were estimated by using logistic regression in univariate and multivariate setting. The sensitivity, specificity, likelihood ratios, and positive predictive value of increased ECFC frequency were calculated for the significantly associated characteristics. Increased frequency of ECFCs resulted independently associated with history of splanchnic vein thrombosis (adjusted odds ratio = , 95% CI = - ), and a summary measure of non-active disease, . hemoglobin of g/dL or lower, white blood cells count of 9/L or lower, and platelet count of 400x10 9/L or lower (adjusted odds ratio = , 95% CI = -) Thirteen patients with splanchnic vein thrombosis non associated with myeloproliferative neoplasms were recruited as controls. We excluded a causal role of splanchnic vein thrombosis in ECFCs increase, since no control had elevated ECFCs. We concluded that increased frequency of ECFCs represents the biological hallmark of a non-active myeloproliferative neoplasm with high risk of splanchnic vein thrombosis. The recognition of this disease category copes with the phenotypic mimicry of myeloproliferative neoplasms. Due to inherent performance limitations of ECFCs assay, there is an urgent need to arrive to an acceptable standardization of ECFC assessment.

Lung cancer is the leading cause of cancer death in men and women worldwide. Brain metastasis (BMs) of non-small cell lung cancer (NSCLC) is the most important cause of death. This study aimed to explore the association of epidermal growth factor receptor (EGFR) mutations and BMs in NSCLC. We analyzed 50 NSCLC patients with BMs and 50 match-paired NSCLC patients with no brain metastases (NBMs). The EGFR mutation status of primary lesions was detected using the amplification refractory mutation system polymerase chain reaction. The BMs patients had a higher frequency of EGFR mutations than the NBMs patients ( vs. % respectively, P < ), in both adenocarcinoma ( vs. %, P = ) and squamous carcinoma ( vs. 0%, P = ). The incidence of BMs in patients with EGFR mutations was higher than in patients with wild-type EGFR ( vs. %, P = 002). NSCLC patients with BMs had a higher incidence of EGFR mutations and those with mutant EGFR had a higher frequency of BMs. EGFR mutations may promote brain metastasis growth of NSCLC.

High frequency trading became common place in the markets following the introduction of incentives offered by exchanges for institutions to add liquidity to the markets. By offering small incentives to these market makers , exchanges gain added liquidity, and the institutions which provide the liquidity also see increased profits on every trade they make, on top of their favorable spreads. Although the spreads and incentives amount to a fraction of 1 cent per transaction, multiplying that by a large number of trades per day amounts to sizable profits for high frequency traders.
