AIM:To evaluate the effects of meal size and three segmentations on intragastric distribution of the meal and gastric motility,by ***:Twelve healthy volunteers were randomly assessed,twice,by *** test meal consisted of 60 or 180 mL of yogurt labeled with 64 MBq 99m Tc-tin *** and posterior dynamic frames were simultaneously acquired for 18 min and all data were analyzed in *** proximal-distal segmentations using regions of interest were adopted for both ***:Intragastric distribution of the meal between the proximal and distal compartments was strongly influenced by the way in which the stomach was divided,showing greater proximal retention after the 180 *** important finding was that both dominant frequencies (1 and 3 cpm) were simultaneously recorded in the proximal and distal stomach;however,the power ratio of those dominant frequencies varied in agreement with the segmentation adopted and was independent of the meal ***:It was possible to simultaneously evaluate the static intragastric distribution and phasic contractility from the same recording using our scintigraphic approach.

Background:It is unknown whether lung-protective ventilation is applied in burn patients and whether they benefit from *** study aimed to determine ventilation practices in burn intensive care units(ICUs)and investigate the association between lung-protective ventilation and the number of ventilator-free days and alive at day 28(vFD-28).Methods:This is an international prospective observational cohort study including adult burn patients requiring mechanical *** tidal volume(v_(T))was defined as v_(T)≤8 mL/kg predicted body weight(PBW).Levels of positive end-expiratory pressure(PEEP)and maximum airway pressures were *** association between v_(T) and vFD-28 was analyzed using a competing risk *** settings were presented for all patients,focusing on the first day of *** also compared ventilation settings between patients with and without inhalation ***:A total of 160 patients from 28 ICUs in 16 countries were *** v_(T) was used in 74%of patients,median v_(T) size was 7.3[interquartile range(IQR)6.2–8.3]mL/kg PBW and did not differ between patients with and without inhalation trauma(p=0.58).Median vFD-28 was 17(IQR 0–26),without a difference between ventilation with low or high v_(T)(p=0.98).All patients were ventilated with PEEP levels≥5 cmH_(2)O;80%of patients had maximum airway pressuresve ventilation is used in the majority of burn patients,irrespective of the presence of inhalation *** of low v_(T) was not associated with a reduction in *** registration:*** *** of registration:9 December 2014.
