Question: Question: Are enemas , suppositories and rectal stimulation effective in accelerating enteral feeding or meconium evacuation in low-birthweight infants : a systematic review?
Answer: Suppositories were ineffective in shortening the time to reach full enteral feeding, and the evidence on enemas was contradictory. Enemas and rectal stimulation did not shorten the time until complete meconium evacuation was reached. Further research into safe, effective interventions to accelerate meconium excretion is needed.

Answer: no


Question: Question: Is vitamin D deficiency in septic patients at ICU admission a mortality predictor?
Answer: In our cohort, septic patients showed a significantly lower vitamin D level than trauma patients in comparison to age cohort patients with the same demographic/clinical characteristics, but no clear relationship between vitamin D level and outcome was found. Further studies with larger samples are needed to clarify the prognostic role of vitamin D and nutraceutical interventions in critically ill patients.

Answer: no


Question: Question: Does repeated apnea-induced contraction of the spleen in cyclists enhance performance in a subsequent time-trial?
Answer: Our present findings reveal that four apneas by cyclists prior to a 4-km time trial led to splenic contraction, but no change in mean power output, the level of hemoglobin, hematocrit, oxygen saturation of the m. vastus lateralis or oxygen uptake.

Answer:
no
