Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

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.

Context: Rural primary health centers frequently treat patients with tick bites. This study compares everyday clinical practice at our primary healthcare center to practices recommended by current scientific evidence.', 'To describe the everyday management of tick bites by different healthcare professionals and to compare this management to evidence-based therapy guidelines.', 'Cross-sectional, descriptive observational study.', 'Data was collected through an anonymous self-completed questionnaire. The form was filled out by a consecutive sample of nurses, physicians and pediatricians of the clinical management unit of Medina-Sidonia (Cádiz).', 'Most nurses in the sample group use some type of product to facilitate the extraction of the tick (10 of the 11 surveyed nurses, 90.9%). The most frequently used products were chloroethyl and local anesthetic. In addition, nine nurses use gentle traction with tweezers (81.82%) to remove the tick. In the physician sample group, 3 out of 12 respondents (25%) prescribe antibiotics in all cases and nine stated that they knew which antibiotic should be used as first choice. In both cases, a high number of healthcare providers confirm giving post-extraction advice to patients: 11 in the medical community (91.66%) and nine nurses (81.82%).
Answer: We conclude that the performance of the healthcare providers that integrate this study does not closely follow general recommendations for extraction, treatment and follow-up care in patients with tick bites. Therefore, there is a need to improve the level of knowledge to ensure quality care in these instances.

Context: Corticotropin-releasing hormone receptor 1 (CRH-R1) in the amygdala and the stria terminalis plays an important role in the activation of central stress circuits. Genetic factors may contribute to the hyperresponsiveness of these circuits in irritable bowel syndrome (IBS).', 'To determine if CRH-R1 SNPs are associated with: (1) a diagnosis of IBS, (2) gastrointestinal (GI) symptoms, and (3) acoustic startle response (ASR) to threat, which is mediated by the amygdala via CRH.', 'Three CRH-R1 SNPS (rs110402, rs242924, and rs7209436) were genotyped using salivary DNA from IBS and healthy control subjects (HCs). Eye blink ASR was obtained during safe (no shock), anticipation (abdominal shock may soon occur) and threat (abdominal shock likely) conditions in a subset of subjects. Associations between each SNP with IBS status, clinical traits and ASR were measured.', '235 IBS patients (mean age 37.5 yrs, 74% F) and 264 HCs (mean age 32.1 yrs, 70% F) were studied. Of these, 57 IBS and 41 HCs underwent the ASR protocol. The presence of IBS was associated with the major allele for all three CRH-R1 SNPs (p=0.009-0.025). Within IBS, the major allele for all three SNPs (p=0.017-0.065) was associated with GI symptom anxiety scores. Within subjects with at least one copy of the major allele for the CRH-R1 SNPs, IBS had significantly lower ASR compared to HCs during threat conditions (p=0.001-0.002). Within IBS, CRH-R1 SNPs were associated with a graded increase in ASR to threat (p=0.007-0.008).
Answer: These findings support that CRH-R1 contributes to the dysregulated stress responsiveness in IBS.
