Question: Question: Does detection of molecular bacterascites in decompensated cirrhosis define a risk with decreased survival?
Answer: BactDNA quantification in ascitic fluid samples using culture-independent 16S rRNA gene-based methods seems to be an interesting approach to identify patients at risk of reduced survival. Our study warrants further evaluation of antibiotic treatment in patients with molecular bacterascites.

Answer: yes


Question: Question: Is prenatal anteroposterior pelvic diameter cutoffs for postnatal referral for isolated pyelectasis and hydronephrosis : more always better?
Answer: Using these thresholds, we could avoid a significant number of followup ultrasounds in the prenatal and postnatal periods, as well as invasive postnatal tests (ie voiding cystourethrography and mercaptoacetyltriglycine scintigraphy) without missing even a single case of obstructive nephropathy requiring surgery.

Answer: no


Question: Question: Is interleukin 6 gene promoter polymorphism associated with ankylosing spondylitis?
Answer: Our results suggest the -174 IL-6 polymorphism does not play an important role in susceptibility to AS. Larger studies are needed to provide more conclusive evidence on the role of -174 IL-6 polymorphism in AS.

Answer:
no
