question:
Question: Are perioperative nonselective non-steroidal anti-inflammatory drugs associated with anastomotic leakage after colorectal surgery?
Answer: There does not appear to be a significant association between perioperative ketorolac use and anastomotic leakage after colorectal surgery. However, further prospective studies are needed to confirm our findings before definitive guidelines on NSAID use perioperatively can be recommended.
answer:
no

question:
Question: Is neutrophil-lymphocyte ratio a reliable predictive marker for early-stage diabetic nephropathy?
Answer: Increased NLR was significantly associated with DN, and high NLR values may be a reliable predictive marker of early-stage DN.
answer:
yes

question:
Question: Does hyperinsulinaemia during exercise suppress hepatic glycogen concentrations in patients with type 1 diabetes : a magnetic resonance spectroscopy study?
Answer: In patients with type 1 diabetes, hyperinsulinaemic and hyperglycaemic conditions during moderate exercise did not suppress hepatic glycogen concentrations. These findings do not support the hypothesis that exercise-induced hypoglycaemia in patients with type 1 diabetes is due to suppression of hepatic glycogen mobilisation.
answer:
no
