Validation the clinical value of good outcome following attempted resuscitation scores in Chinese populations in predicting the prognosis of in-hospital cardiac arrest / 中华危重病急救医学

Objective:To verify the clinical value of the good outcome following attempted resuscitation (GO-FAR) score in predicting the neurological status of patients with in-hospital cardiac arrest (IHCA) in the Chinese population.Methods:The clinical data of patients with IHCA who were admitted to the Zigong Fourth People's Hospital from January 1 to December 31, 2020 were retrospectively analyzed. Used Glasgow-Pittsburgh cerebral performance category (CPC) score 1 point as the end point, the subjects were divided into 4 groups according to the score: ≤ 0 group, 1-8 group, 9-20 group and ≥ 21 group. Taken the group which GO-FAR score ≤ 0 as the reference group, the odds ratio ( OR) of the other three groups compared with this group was calculated. The receiver operator characteristic curve (ROC curve) was performed to evaluate the predictive value of the GO-FAR score in favorable neurological outcome. A calibration curve was drawn for the Hosmer-Lemeshow test to analyze the degree of calibration of the GO-FAR score for predicting good neurological outcome. Results:A total of 230 IHCA patients were enrolled in the study, including 130 males, aged 74 (65, 81) years old, and 23 case (10.0%) had good neurological prognosis. There were statistically significant differences in GO-FAR-related variables, including age, a normal neurological function on admitted, acute stroke, metastatic cancer, septicemia, medical noncardiac admission, hepatic insufficiency, hypotension, renal insufficiency or dialysis, respiratory insufficiency, pneumonia, etc (all P < 0.05). Taken the GO-FAR score ≤ 0 group as the reference group, the OR values of good neurological prognosis in the GO-FAR score 1-8 group were 0.54 [95% confidence interval (95% CI) was 0.17-1.53, P = 0.250], 9-20 group were 0.17 (95% CI was 0.02-0.67, P = 0.009) and ≥ 21 group were 0.25 (95% CI was 0.05-0.85, P = 0.025). The area under the ROC curve (AUC) of the GO-FAR score for predicting favorable neurological outcome in IHCA patients was 0.653 (95% CI was 0.529-0.777, P = 0.015) and there was no significant difference in Hosmer-Lemeshow test ( P = 0.311). All these suggested that there was no significant difference between the predicted value and the actual value. Conclusions:GO-FAR score can be applied to predict neurological prognosis of IHCA patients in Chinese population. It can help clinicians to predict the prognosis of cardio-pulmonary resuscitation (CPR) and propose critical recommendations in treatment for these patients or their families.

Effectiveness of continuous positive airway pressure ventilation in improving genioglossus electromyography in patients with moderate to severe obstructive sleep apnea / 中华耳鼻咽喉头颈外科杂志

Objective@#To compare the changes of genioglossus electromyography (GGEMG) with and without continuous positive airway pressure (CPAP) ventilation in moderate to severe obstructive sleep apnea (OSA) patients.@*Methods@#Each of subjects, including male snorers and non-snorers, underwent polysomnography (PSG) with synchronous GGEMG recording with intra-oral bipolar silver ball electrodes at the Sleep Center of Beijing Tsinghua Changgung Hospital from August 2016 to Sepember 2017. Manual CPAP pressure titration and with GGEMG were performed in patients diagnosed moderate to severe OSA. T-test was used to compare the changes of GGEMG in OSA group (n=12, AHI (65.90+23.67) events/h) and control group (n=6, AHI(2.30+1.93) events/h) before and after CPAP treatment.@*Results@#Variables of GGEMG (including tonic, peak and phasic GGEMG) were higher in OSA group than in control group during both wakefulness and non rapid eye movement(NREM) sleep. However, with CPAP treatment, the GGEMG variables were significantly decreased in OSA group during NREM sleep(tonic GGEMG: 1.23%±0.73% vs. 2.54%±1.12%, t=4.024, P=0.002; peak GGEMG: 12.37%±13.19% vs. 26.98%±15.52%, t=2.795, P=0.017; phasic GGEMG: 3.81%±2.47% vs. 8.82%±3.84%, t=5.113, P<0.001).@*Conclusions@#CPAP treatment can eliminate respiratory events and maintain airway patency. It is helpful to normalize the excessive GGEMG response in OSA patients during sleep, which has therapeutic significance to alleviate and prevent genioglossal neuromuscular lesions.

Analysis of polysomnography results between pre- and post-operation in pediatric obstructive sleep apnea hypopnea syndrome patients / 中华耳鼻咽喉头颈外科杂志

Objective@#To determine the objective effects of adenotonsillectomy on pediatric obstructive sleep apnea hypopnea syndrome (OSAHS) through analyzing the polysomnography (PSG) results between pre and post-operation.@*Methods@#A total of 56 pediatric OSAHS patients were included who underwent adenoidectomy or/and tonsillectomy and completed PSG follow-up from January 1, 2017 to March 31, 2018. All the pediatric patients who underwent adenoidectomy or/and tonsillectomy during the research period were arranged to take a preoperative PSG study. Patients who were diagnosed OSAHS would be encouraged to complete a follow-up PSG study ranged from1 to 3 months after surgery. The parameters of respiration and sleep architecture of PSG were compared and analyzed. The paired student t test was used to compare preoperative and postoperative mean values. The unpaired student t test was used to compare quantitative variables among different groups. The rank sum test was used if the data were abnormal distribution.@*Results@#Totally 238 patients completed preoperative PSG study, 62 patients were diagnosed as pediatric OSAHS, 56 eligible patients finished post-operative PSG. Hypopnea was the majority in all type of respiratory events in 56.45% (35/62) subjects, while central apnea as the majority in 29.03% (18/62) subjects who can also get significant CAI decrease after surgery. However, obstructive apnea as the majority only exist in 14.52% (9/62) subjects. The short-term cure rate of pediatric OSAHS was 85.71% (48/56). The postoperative AHI, MAI, CAI, HI, ODI, LoSpO2, percentage of stage I sleep and arousal index were significantly decreased, however, the OAI was no statistical decrease. The percentage of stage Ⅱ and rapid eye movement (REM) sleep were significantly increased, while no significant change in percentage of slow wave sleep and sleep efficiency(t=2.32, P=0.017).@*Conclusions@#Pediatric OSAHS manifest different characteristics of respiratory events from that of adults. Adenotonsillectomy can significant decrease respiratory events and improve sleep architecture, however, there are still some patients who can′t be completely relieved with adenotonsillectomy.

Study on serum levels of adiponectin and its associated factors in type 2 diabetes with insulin treatment / 中国糖尿病杂志

Objective To explore the effect of adiponectin on the pathophysiology and treatment of type 2 diabetes. Methods 50 patients with newly diagnosed type 2 diabetes were given insulin intensive therapy.Body mass index(BMI), blood lipids, blood glucose, insulin and adiponectin were measured before and after the insulin treatment.36 healthy persons were selected to match for sex and age with diabetes patients. Results In type 2 diabetes patients, before insulin intensive treatment,the level of adiponcetin was 4.28(2.11-6.38)μg/L and arose to 12.26(8.22-16.00)μg/L after 12.6±2.1 day insulin treatment.In healthy persons, the level of adiponectin was 9.56(7.92-11.61)μg/L.There was significant difference among the three groups.Adiponectin was negatively correlated with BMI and triglyceride and positively correlated with insulin action index (IAI) and high density lipoprotein (HDL). Conclusions Adiponectin plays a major role in the pathophysiology and treatment of newly diagnosed type 2 diabetes.

Reasonable application of continuous subcutaneous insulin infusion in type 2 diabetic in-patients / 中华内分泌代谢杂志

Objective To study the regiments of continuous subcutaneous insulin infusion (CSII) in admitted type 2 diabetic patients, and to analyse the factors related to its effectiveness and insulin dosage. Methods A total of 1 276 type 2 diabetic patients were treated by CSII. The total efficacy of CSII was evaluted. The use of CSII was also analysed in the newly diagnosed patients, elderly patients, and patients with obese or infectious disease. Results The excellent control of blood glucose were achieved in (5.7±2.6)days in the dosage more early and quickly in the newly diagnosed group than that in the previously diagnosed group after the blood glucose levels achieved good control. The percentage of the patients reached the clinical relieve was also higher in the newly diagnosed group. The incidence of hypoglycemia was significantly higher in the elderly patients with lower basal insulin dosage at night. The bolus insulin dosage in the obese patients was higher than that in the non-obese patients. The patients with infectious disease usually have a higher basal insulin dosage than those without infectious disease. The days needed for achieving good control of blood glucose and the insulin dosage were related to infectious factors, the basal blood glucose and obesity. Conclusion The application of CSII among the patients is varied with different conditions. Blood glucose level, body mass index and infection factors are important to determine the initial insulin dosage.
