PURPOSE To predict clinically significant prostate cancer (cs-PCa) by combining the Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) score based on biparametric magnetic resonance imaging (bp-MRI) and clinical indicators in men with prostate-specific antigen (PSA) levels in the gray zone of 4-10 ng/mL. METHOD We retrospectively analyzed 364 patients with elevated PSA levels in the gray zone who had pathologically confirmed disease and had undergone MRI examinations from January 2015 to October 2019; a training group (n = 255) and validation group (n = 109) were randomly established. Multivariate logistic regression analysis of the training group was performed to identify the independent predictors for cs-PCa, thereby establishing a predictive model that was evaluated in the training and validation groups by analyzing the receiver operating characteristic (ROC) curve. RESULTS In the training group, the PI-RADS v2 score and prostate volume (PV) were independent predictors of cs-PCa (P  less then  0.05). The prediction model comprising the PI-RADS v2 score and PV had a larger AUC than the other predictors alone in the training group. The diagnostic sensitivity and specificity of the prediction model were 84.1 % and 83.4 %, respectively. The prediction model was indicated to have better predictive performance in the validation group. CONCLUSIONS The prediction model exhibits a satisfactory predictive value for cs-PCa in men with PSA levels in the gray zone. PI-RADS v2 is the strongest univariate predictor for the detection of cs-PCa in men with PSA in the gray zone, but combining this with the PV can provide superior predictive ability. RRx-001 in vivo Extracellular vesicles (EVs), which are small cell-derived compartments, take part in numerous different physiological processes. The contents of EVs reveal the cell of origin and indicates pathophysiological states in different diseases. In pregnancy disorders, changes have been reported in the composition, bioactivity and concentration of placental and non-placental EVs. The purpose of this study was to monitor the effects on EVs in patients receiving intravenous immunoglobulin (IVIG) or placebo (albumin) treatment due to recurrent pregnancy loss (RPL). In a placebo-controlled trial study of IVIG treatment, plasma collected from 39 women with RPL were investigated using the Extracellular Vesicle Array (EV Array). Plasma was sampled consecutively (from gestational week (GW) 5) and the protein phenotypes of the smaller EVs (sEVs) were analyzed for the presence of 34 markers. The levels of sEVs or changes in their levels in early pregnancy were correlated with treatment. There was statistically significant increased levels of sEVs in patients who received IVIG versus placebo. In conclusion, the treatment with high-doses of IVIG clearly boosted the production and release of sEVs to the circulation; however, the biological role of this boost remains to be clarified in further studies. BACKGROUND The role of decidual natural killer (dNK) cells in normal and complicated pregnancy and their relation with peripheral NK (pNK) cells remains unclear. The study aim was phenotypic analysis of pNK and dNK cells at time of miscarriage in recurrent spontaneous miscarriage (RSM) patients to assess whether measuring levels of pNK cell populations can reflect changes in dNK cells or not. METHODS This study included 40 middle aged pregnant women in the 1st trimester subjected to evacuation because of a current miscarriage. They had a history of previous ≥ two unexplained miscarriages. Frequencies of pNK and dNK cells, based on the expression of CD56, CD16, inhibitory (CD158b) and activating (CD161) Killer immunoglobulin-like receptors (KIRs), were detected by flow cytometry. RESULTS Percentages of CD56+ NK cells in peripheral blood and decidua were 17.5 % and 17.3 %, respectively. In both blood and decidua, CD56dim NK cells were exceeding CD56bright NK cells. The CD56dim CD16- NK cells were the predominating subset of NK cells, followed by CD56dim CD16dim. No substantial differences were detected in the levels of KIRs expression by the different NK subsets between blood and decidua. Abnormal up-regulation of both CD161 and CD158b on NK cells was observed in blood and decidua. CONCLUSION At the time of miscarriage, patients with RSM have an extremely active immune system and an increased number of toxic NK cells both in blood and decidua. The pNK cells reflect dNK cell changes during miscarriage and may be a useful non-invasive predicting tool in reproductive failure setting. BACKGROUND Ambient air pollution has recently been related to type 2 diabetes mellitus (T2DM), a disease that has caused an economic and health burden worldwide. Evidence of an association between air pollution and T2DM was reported in the United States and Europe. However, few studies have focused on the association with high levels of air pollutants in a developing country. OBJECTIVES We conducted a 12-year cohort study to assess the incidence and mortality of T2DM associated with long-term exposure to PM10, SO2, and NO2. METHODS A retrospective cohort with participants from four cities in northern China was conducted to assess mortality and incidence of T2DM from 1998 to 2009. Incidence of T2DM was self-reported, and incident intake of an antidiabetic drug or injection of insulin simultaneously and mortality of T2DM was obtained from a family member and double checked against death certificates provided from the local center for disease control and prevention. Individual pollution exposures were the mean concentrations of pollutants estimated from the local environmental monitoring centers over the survival years. Hazard ratios (HRs) were estimated using Cox regression models after adjusting for potential confounding factors. RESULTS A total of 39 054 participants were recruited into the mortality cohort, among which 59 subjects died from T2DM; 38 529 participants were analyzed in the incidence cohort, and 1213 developed new cases of T2DM. For each 10 μg/m3 increase in PM10, SO2, and NO2, the adjusted HRs and 95% confidence interval (CI) for diabetic incidence were 1.831 (1.778, 1.886), 1.287 (1.256, 1.318), and 1.472 (1.419, 1.528), respectively. Similar results can be observed in the analysis of diabetic mortality with HRs (95% CI) up to 2.260 (1.732, 2.950), 1.130 (1.042, 1.225), and 1.525 (1.280, 1.816), respectively. CONCLUSIONS Our results suggested that long-term exposure to high levels of PM10, SO2, and NO2 increase risk of incident and mortality of T2DM in China.
