ABSTRACT

Background: The sulfonylurea receptor 1-transient receptor potential melastatin 4 (SUR1-TRPM4) channel is a target key mediator of brain edema. Sulfonylureas (SFUs) are blockers of the SUR1-TRPM4 channel. We made two assessments for the pretreatment of SFUs: (1) whether it associates with lower perihematomal edema (PHE) and (2) whether it associates with improved clinical outcomes in diabetic patients who have acute basal ganglia hemorrhage. Methods: This retrospective case-control study was conducted in diabetic adults receiving regular SFUs before the onset of intracerebral hemorrhage (ICH). All of the patients received the clinical diagnosis of spontaneous basal ganglia hemorrhage. The diagnosis was confirmed by a CT scan within 7 days after hemorrhage. For each case, we selected two matched controls with basal ganglia hemorrhage based on admission time (≤5 years) and age differences (≤5 years), with the same gender and similar hematoma volume. The primary outcome was PHE volume, and the secondary outcomes were relative PHE (rPHE), functional independence according to modified Rankin Scale score and Barthel Index at discharge, and death rate in the hospital. Results: A total of 27 patients (nine cases and 18 matched controls), admitted between January 1, 2009 and October 31, 2018, were included in our study. There was no significant association between SFU patients and non-SFU patients on PHE volumes [15.4 (7.4-50.2 ml) vs. 8.0 (3.1-22.1) ml, p = 0.100]. Compared to non-SFU patients, the SFU patients had significantly lower rPHE [0.8 (0.7-1.3) vs. 1.5 (1.2-1.9), p = 0.006]. After we adjusted the confounding factors, we found that sulfonylureas can significantly reduce both PHE volume (regression coefficient: -13.607, 95% CI: -26.185 to -1.029, p = 0.035) and rPHE (regression coefficient: -0.566, 95% CI: -0.971 to -0.161, p = 0.009). However, we found no significant improvement in clinical outcomes at discharge, in the event of pretreatment of SFUs before the onset of ICH, even after we adjusted the confounding factors. Conclusion: For diabetic patients with acute basal ganglia hemorrhage, pretreatment of sulfonylureas may associate with lower PHE and relative PHE on admission. No significant effect was found on the clinical outcomes when the patients were discharged. Future studies are needed to assess the potential clinical benefits using sulfonylureas for ICH patients.

ABSTRACT

Objective To investigate the energy intake and complications of continuous and intermittent pump feeding in acute stroke patients and provide a theoretical evidence to support for clinical treatment.Methods From April 2012 to June 2016,69 acute srtoke patients on the nasogastric tube feeding and admitted in the Department of Neurology intensive care unit in Xijing Hospital were enrolled and randomly assigned to have continuous or intermittent pump feeding.The primary endpoint was the efficacy in supplying the desired amount of nutrients by the fifth day and complications(hospital-acquired pneumonia,diarrhea,gastric retention,gastrointestinal bleeding)during the first week.The secondary endpoint was nutritional assessments(albumin,prealbumin,transferrin,hypersensitive c-reactive protein)in the first week.Results Both groups were comparable in acute physiology and chronic health evaluation Ⅱ(13.3±4.7 vs.12.9±4.5),Glasgow coma scale[10(7.2,14)vs.9.5(7.7,12)],National Institute of Health stroke scale[17(15,19)vs.16(13,20)],and Barthel scores[5(0,12.5)vs.10(5,15)](all P>0.05).It was no significantly different in the achievement percentage of the energy determined in the fifth day [93.9%(77.9%,99.8%)in continuous group and 84.8%(75.7%,93.9%)in intermittent group(U=0.144,P>0.05).Intermittent pump feeding significantly reduced the rate of hospital-acquired pneumonia in the first week when compared with continuous pump feeding(58.3%vs.33.3%,X2=4.327,P=0.038),and both groups displayed a moderate number of digestive complications without significant differences,including diarrhea(30.6%vs.27.3%,X2=0.09,P=0.764),gastric retention(2.78%vs.3.03%,X2=0.001,P=1.000),and gastrointestinal bleeding(5.56%vs.9.10%,X2=0.010,P=0.920).No difference could be demonstrated in serum protein markers between two groups in the first week,including prealbumin[0.17(0.13,0.20)g/L vs.0.18(0.15,0.24)g/L,P=0.195),transferrin[1.90(1.52,2.20)g/L vs.1.94(1.65,2.06)g/L,P=0.747),and hypersensitive C-reactive protein[22.5(8.3,50.1)mg/L vs.14.6(6.5,30.5)mg/L,P=0.205].Conclusions Both continuous and intermittent pump feeding can reach the target predictive nutrition(100%of calculated caloric requirements)without statistical differences in the incidences of gastrointestinal complications,and the rate of HAP is lower in intermittent group.Intermittent enteral nutrition can be used as an appropriate method of enteral nutrition support to improve the nutritional status in critically acute stroke patients.

ABSTRACT

Objective To explore the relationship between gastric juice pH and hospital-acquired pneumonia ( HAP) , the gastric bacterial colonization and etiology of HAP in neurologic intensive care unit patients by monitoring gastric juice pH value.Methods From October 2014 to May 2015, consecutive seventy-two tube feeding patients admitted in the Department of Neurology Intensive Care Unit in Xijing Hospital were enrolled in this research.The type and concentration of pathogens from gastric contents were collected, while samples from upper respiratory tract and pharynx were detected dynamically at the same time.Results (1)The group with new onset HAP was higher in gastric juice pH (6.4(5.4,6.4) vs 5.4 (2.5, 6.4), Z=-2.37, P=0.01); (2) The isolation rate of colonized bacteria in gastric cavity was associated with the pH of gastric juice , achieving 60.8% ( 42/69 ) in HAP group; ( 3 ) When the gastric juice pH was >4, the isolation rate of Gram-negative bacilli in gastric cavity obviously increased (63.6%(28/44) vs 35.7%(10/28),χ2 =5.323, P=0.021); (4)The same pathogens were found in stomach-pharynx-upper respiratory tract in 7 cases ( 17.5%) of the total 40 HAP patients.Conclusion Increased gastric juice pH was associated with gastric colonization , especially Gram-negative bacilli , and may lead to a higher incidence of new onset HAP in patients on enteral feeding.
