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: Urinary dysfunction (UD) is common after rectal cancer treatment, but the contribution of each treatment component (surgery and radiotherapy) to its development remains unclear. This study aimed to evaluate UD during 5 years after total mesorectal excision (TME) and to investigate the influence of preoperative radiotherapy (PRT) and surgical factors.', 'Patients with operable rectal cancer were randomized to TME with or without PRT. Questionnaires concerning UD were completed by 785 patients before and at several time points after surgery. Possible risk factors, including PRT, demographics, tumour location, and type and extent of resection, were investigated by multivariable regression analysis.', 'Long-term incontinence was reported by 38.1 per cent of patients, of whom 72.0 per cent had normal preoperative function. Preoperative incontinence (relative risk (RR) 2.75, P = 0.001) and female sex (RR 2.77, P < 0.001) were independent risk factors. Long-term difficulty in bladder emptying was reported by 30.6 per cent of patients, of whom 65.0 per cent had normal preoperative function. Preoperative difficulty in bladder emptying (RR 2.94, P < 0.001), peroperative blood loss (RR 1.73, P = 0.028) and autonomic nerve damage (RR 2.82, P = 0.024) were independent risk factors. PRT was not associated with UD.\Question: Is urinary dysfunction after rectal cancer treatment mainly caused by surgery?
[A]: UD is a significant clinical problem after rectal cancer treatment and is not related to PRT, but rather to surgical nerve damage.


[Q]: Context: To evaluate the relevance of systematic screening for neonatal metabolic acidosis at birth as part of perinatal audit.', 'For every baby, born in Ziekenhuis Oost Limburg, Genk Belgium between 1/1/2010 and 31/12/2010, cord blood was analysed to diagnose metabolic acidosis, defined as arterial or venous pH ≤ 7.05 or 7.17 respectively, in association with base excess of ≤ -10\u2008mmol/L. Three observers identified indicators for suboptimal peripartal care with likely contribution to metabolic acidosis. In a multidisciplinary consensus meeting, these indicators were classified into 5 categories : (a) fetal monitoring error (b) labour management error, (c) instrumental vaginal delivery for fetal distress within 2\u2008h of second stage, (d) non-obstetric medical complications, (e) preterm births or accidental cases at term.', 'In a total of 2117 neonates, there were 11 intra-uterine, 1 intrapartum and 3 early neonatal deaths, bringing early perinatal mortality rate at 7.1‰. Metabolic acidosis was identified in 23 (1.1%) babies, of which 21 (91.3%) left hospital in good clinical condition. Two babies (0.9‰), born in category c, had chronic neurologic symptoms.\Question: Do identification of neonatal near miss by systematic screening for metabolic acidosis at birth?
[A]: Systematic screening for neonatal metabolic acidosis caused a 2.5-fold increase of case identifications eligible for perinatal audit and opened perspectives towards rationalised improvement of perinatal care, in addition to the information obtained from cases of perinatal mortality. Next to indicators of perinatal mortality, perinatal audit programs should include neonatal metabolic acidosis as an extra parameter for quality assessment of perinatal care.


[Q]: Context: Children with nephrotic syndrome (NS) are usually treated with long-term low dose alternate day prednisolone with or without glucocorticoid sparing therapy, such as levamisole or ciclosporin, to maintain remission. The degree of hypothalamic-pituitary-adrenal axis (HPA) suppression with such therapeutic strategies has not been studied systematically. HPA suppression could cause a relapse or adrenal crisis.', 'To study the risks of HPA suppression, a modified low dose synacthen test (0.5 mug) was administered to 32 patients (22 male,10 female) with a mean age of 9.7 years (range 3.8-17.6 years) with NS receiving long-term alternate day prednisolone for over 12 months. Twelve patients received alternate day prednisolone, 11 alternate prednisolone+levamisole and nine alternate prednisolone+ciclosporin. All patients were followed up for 3 years and the relapse rate noted.', '20/32 (62.5%) patients had a peak serum cortisol concentration of <500 nmol/l, which suggested suboptimal cortisol secretion and possible HPA suppression. 10/12 children in the prednisolone group and 8/11 in the levamisole group had a suboptimal cortisol response compared with 2/9 in the ciclosporin group. During follow-up, the 20 children who had a suboptimal cortisol response had significantly more relapses (95 relapses) compared to the 12 children with a normal cortisol response who had 24 relapses (p = 0.01).\Question: Does adrenocortical suppression increase the risk of relapse in nephrotic syndrome?
[A]:
Children with NS receiving long-term alternate day prednisolone therapy are at risk of developing HPA suppression and should be evaluated using the modified synacthen test. Children with evidence of HPA suppression are at a greater risk of relapse.
