[EX Q]: Context: i ne prognostic relevance of hematological parameters in cardiovascular diseases has been well demonstrated. The purpose of the present study is to investigate the association between the hematological parameters, particularly neutrophil to lymphocyte ratio (NLR), and outcomes of aortic dissection (AD).', 'Two hundred patients diagnosed with AD were retrospectively recruited and compared with 76 subjects with ascending aortic dilatation (AAD) and 92 subjects with normal aortic diameters. The independent relation between hematological parameters and in-hospital mortality was analyzed by regression analysis.', 'The NLR was significantly higher in the AD group compared to the AAD and control groups (median 8.83 [8.13] vs. median 1.95 [1.10] vs. median 1.71 [0.77], respectively; p = 0.01). The NLR was higher in the deceased (n = 57) compared to the surviving patients (n = 143) (median 10.37 [10.86] vs. median 7.84 [8.17]; p = 0.01). Receiver operating curve (ROC) analysis revealed that a NLR measurement higher than > 8.78 predicted in-hospital mortality for patients with acute aortic dissection with a sensitivity of 67.4% and a specificity of 57.2% (AUC: 0.672; p = 0.01). In multivariate logistic regression analysis, increased aortic diameter, acute dissection, and increased levels of NLR remained as the independent markers of in-hospital mortality within the study population.
Answer: In patients with AD, NLR levels were increased compared to patients with AAD and controls and were independently associated with in-hospital mortality. This finding implicates that admission hematological parameters may have clinical importance in evaluating the mortality risk in patients with AD.

[EX Q]: Context: Increased progesterone level during follicular phase seemed to be associated with decreased pregnancy rate.', 'A prospective cohort study, 1.1.2012 - 31.8.13. The Progesterone (P) and Progesterone/Estrogen (P/E2) level on ovulation induction day were compared between the protocols and the different gonadotropins used. Roc analysis was calculated to determine the cutoff of P/E2 to predict delivery rates. P/E2 ratio was calculated as PX1000/e2 level.', 'One hundred thirty-nine patients were enrolled to the study. No difference in the P level at hCG stimulation day between different protocols, however, E2 and P/E2 ratio were significantly lower in the long protocol compare with antagonist protocol 1757.7923.2 vs. 1342.91223; P=0.003 and 0.480.31 vs. 0.830.87; P=0.038). The endometrium was significantly thicker in the long group compare with short and antagonist. Significantly more top-quality embryos (TOP) were achieved in the antagonist group. Comparable results between the types of gonadotropins used in regards with cycle characteristics and pregnancy and delivery rates. The P/E2 ratio which can predict live birth rate was found to be 0.45, AUC=0.632, p=0.02 and 95% CI 0.525-0.738 and a significantly higher pregnancy and delivery rates at a P/E2 bellow 0.45.
Answer: Endometrial receptivity is determined by the complex interactions of E2 and P.

[EX Q]: Context: To test the hypothesis that core and suggestive features in possible dementia with Lewy bodies (DLB) would vary in their ability to predict an abnormal dopamine transporter scan and therefore a follow-up diagnosis of probable DLB. A further objective was to assess the evolution of core and suggestive features in patients with possible DLB over time depending on the (123)I-FP-CIT SPECT scan result.', 'A total of 187 patients with possible DLB (dementia plus one core or one suggestive feature) were randomized to have dopamine transporter imaging or to follow-up without scan. DLB features were compared at baseline and at 6-month follow-up according to imaging results and follow-up diagnosis.', "For the whole cohort, the baseline frequency of parkinsonism was 30%, fluctuations 29%, visual hallucinations 24%, and REM sleep behavior disorder 17%. Clinician-rated presence of parkinsonism at baseline was significantly (p = 0.001) more frequent and Unified Parkinson's Disease Rating Scale (UPDRS) score at baseline was significantly higher (p = 0.02) in patients with abnormal imaging. There was a significant increase in UPDRS score in the abnormal scan group over time (p < 0.01). There was relatively little evolution of the rest of the DLB features regardless of the imaging result.
Answer: In patients with possible DLB, apart from UPDRS score, there was no difference in the evolution of DLB clinical features over 6 months between cases with normal and abnormal imaging. Only parkinsonism and dopamine transporter imaging helped to differentiate DLB from non-DLB dementia.
