In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[Q]: Context: To determine the role of factor V Leiden and prothrombin gene mutation in the pathogenesis of unexplained second and third trimester nonrecurrent fetal loss.', 'One hundred and fourteen women with unexplained nonrecurrent late fetal loss made up the study group, and 106 normal pregnant women with a history of delivery of at least one healthy fetus and no history of late fetal loss made up the control group. The study group was further divided into two subgroups: second (n = 36) and third (n = 78) trimester fetal loss. All women were tested for factor V Leiden and G20210A prothrombin gene mutations.', 'Twenty-one (18.4%) of the women in the study group and seven (6.6%) of the women in the control group were heterozygous carriers of factor V Leiden mutation (OR = 3.19). Eleven (9.6%) of the women in the study group and three (2.8%) of the women in the control group were heterozygous carriers of prothrombin gene mutation (OR = 3.66). In assessing with regard to trimesters, 18 (23%) factor V Leiden and 10 (12.8%) prothrombin gene mutations were present in the group of third trimester fetal loss (OR = 4.24 and OR = 5.04, respectively). Three (8.3%) factor V Leiden and one (2.7%) prothrombin gene mutation were detected in women with second trimester fetal loss (OR = 1.28 and OR = 0.40, respectively).\Question: Is third trimester nonrecurrent fetal loss associated with factor V Leiden and prothrombin gene mutations?
[A]: Factor V Leiden and prothrombin gene mutations were associated with third trimester nonrecurrent fetal loss. These mutations should be screened in women with third trimester but not second trimester unexplained nonrecurrent late fetal loss.


[Q]: Context: Monitoring renal function is crucial in children undergoing chemotherapy. To date, a combination of routine serum creatinine (SCR) monitoring with occasional determination of creatinine clearance ratio (CCR) is widely used as clinical standard for this purpose. Both methods have their limitations regarding diagnostic value (SCR) or practicability (CCR), especially in young children. Diagnostic alternatives, such as glomerular filtration rate (GFR) estimation formulas have not been proved to be superior. The aim of the study was to evaluate whether serum cystatin C (CysC) may have a diagnostic impact on pediatric patients.', 'CysC, SCR, several GFR estimation formulas (Counahan-Barratt, Ghazali-Barratt, Schwartz, Shull, Traub), and CCR were studied in 80 pediatric cancer patients (age range: 0.17-17.9 years) during their chemotherapy. Special attention was given to children under the age of 3 in whom accurate urine collection for CCR is difficult.', 'All parameters correlated similarly well with CCR. Total accuracy was 66% and 67% for CysC and SCR, respectively. In very young children (<3 years), correlation with CCR was for CysC r = -0.74 with an area under the curve (AUC) of 0.646, and for SCR r = -0.27 with AUC = 0.594. Total accuracy was 60% for CysC, 50% for SCR.\Question: Is serum cystatin C a suitable marker for routine monitoring of renal function in pediatric cancer patients , especially of very young age?
[A]: CysC represents a suitable marker for monitoring renal function in pediatric cancer patients. In young children (<3 years), CysC may have a better diagnostic value than SCR. Future studies should show if CysC can improve renal monitoring by replacing SCR, especially in very young children.


[Q]: Context: Erythromycin has been found to be a gastrointestinal prokinetic agent of hypertonic liquids, while acute hyperglycemia has been associated with delayed gastric emptying in diabetic patients.', 'To investigate whether hyperglycemia, per se, reduces gastric motility during erythromycin-induced acceleration on gastric emptying of hypertonic liquids in diabetic patients.', 'In 12 type-I diabetic patients following a hypertonic radiolabeled liquid meal, gastric emptying was measured scintigraphically during normoglycemia (5-8.9 mmol/l glucose) or hyperglycemia induced by intravenous (16-19 mmol/l) glucose infusion. The tests were performed on 4 separate days in random order after administering either placebo or 200 mg i.v. erythromycin.', 'In the hyperglycemic state compared to normoglycemia, the gastric emptying of the hypertonic liquid was reduced after placebo or erythromycin administration. The lag-phase duration (17.8+/-5.5 and 7.8+/-4.5 vs. 10.8+/-3.4 and 3.7+/-2.5 min, respectively, p<0.001), the overall gastric emptying time of the half meal (52.8+/-13 and 24.9+/-5.5 vs. 42.5+/-10.5 min and 16.6+/-6 min, respectively, p<0.001) and the retained percentage of liquid meal in the stomach at 60 and 100 min postprandially (p<0.001) were significantly increased.\Question: Does induced-hyperglycemia attenuate erythromycin-induced acceleration of hypertonic liquid-phase gastric emptying in type-I diabetic patients?
[A]:
The erythromycin-induced acceleration on gastric emptying of hypertonic liquids in diabetic patients is related to the plasma glucose level. The induced hyperglycemia reduces the erythromycin-induced acceleration of liquid-phase gastric emptying, decreasing the overall gastric emptying rate. In spite of the inhibitory effect of induced hyperglycemia on the gastric emptying of hypertonic liquids, erythromycin is still able to accelerate the emptying rate and could prove to be a useful prokinetic agent under hyperglycemic conditions.
