Meta-analysis of the success rate of heartbeat recovery in patients with prehospital cardiac arrest in the past 40 years in China.

BACKGROUND: Systematic evaluation of the successful heartbeat recovery rate (HRR) in patients during the platinum ten minutes after cardiac arrest. METHODS: The databases of CNKI (January 1979-March 2019), Chongqing VIP (January 1989-March 2019), Wanfang (January 1990-March 2019) and Web of Science (1900-May 2020) were searched. To collect the clinical data of patients with cardiac arrest before hospitalization and analyze the cardiopulmonary resuscitation (CPR) at different times. Literature selection and data extraction were carried out by two researchers independently, and the meta package of R software (version 3. 61) was used for analysis. RESULTS: A total of 116 papers met the inclusion criteria, including 37,181 patients. Of these patients, 3367 had their heartbeats successfully restored. The results showed a high degree of heterogeneity (χ2 = 6999.21, P < 0.01, I2 = 97.6%). The meta-analysis was conducted using a random-effects model. The combined effect size was 0.199 (0.157-0.250). (1) According to the five CPR groups (International Cardiopulmonary Resuscitation Guide 2000, 2005, 2010, 2015 and other versions), the HRR of other versions [0.264 (0.176-0.375)] was higher than the International Cardiopulmonary Resuscitation 2005 edition [0.121 (0.092-0.158)]. (2) The rescue time was divided into the 0 to ≤5 min group, the 5 to ≤10 min group, the 10 to ≤15 min group, and the > 15 min group. The HRR were 0.417 (0.341-0.496), 0.143 (0.104-0.193), 0.049 (0.034-0.069), and 0.022 (0.009-0.051), respectively. The HRR was higher in the 0 to ≤5 min group than in the 5 to ≤10 min group, the 10 to ≤15 min group and the > 15 min group. There was no difference between the 10 to ≤15 min group and the > 15 min group. (3) When the groups were stratified with the cutoff of 10 min, the ≤10 min group HRR [0.250 (0.202-0.306)] was higher than the > 10 min group rate [0.041 (0.029-0.057)]. (4) The HRR of the telephone guidance group was [0.273 (0.227-0.325)] lower than that of the 0 to ≤5 min group [0.429 (0.347-0.516)] but higher than that of the 5 to ≤10 min group, the 10 to ≤15 min group, and the > 15 min group. (5) The HRR of the witness group [0.325 (0.216-0.458)] was not different from that of the 0 to ≤5 min group, but it was higher than those of the 5 to ≤10 min group, the 10 to ≤15 min group and the > 15 min group. (6) There was no significant difference HRR between the witnessed group, the telephone guidance group and the ≤10 min group. CONCLUSIONS: (1) The HRR is time-sensitive, and early rescue can improve it. (2) CPR performed within the platinum ten minutes must be executed by the public, and other forces are auxiliary. (3) The concept of peri-cardiac arrest period (PCAP) should be established and improved to guide CPR.

Influence of Marital Status on the Quality of Life of Chinese Adult Patients with Epilepsy.

BACKGROUND: Epilepsy is a chronic disorder characterized by recurrent seizures and has significant psychological and social consequence for everyday living. Epilepsy affects various aspects of ones' social life. The present study aimed to investigate the influence of marital status on the quality of life of adult Chinese patients with epilepsy. METHODS: This study surveyed 805 Chinese adults who have been clinically diagnosed with epilepsy for longer than 1 year in 11 hospitals in Beijing. In this survey, 532 (66.1%) participants were married. All of them completed the case report form with enquiries on demographic data, social factors, and illness. The marriage status of adult epileptic quality of life was the dependent variable, and demographic data and clinical data were independent variables, analyzed through the multiple linear regression analysis methods. The patients' quality of life was assessed using the Quality of Life in patients with Epilepsy-31 items (QOLIE-31) questionnaire, the Patient Health Questionnaire-9 items (PHQ-9), and the Generalized Anxiety Disorder-7 items (GAD-7). RESULTS: The PHQ-9 and GAD-7 scores in the unmarried group (PHQ-9 = 6.0 and GAD-7 = 5.0) were significantly higher than that of the married group (PHQ-9 = 4.0 and GAD-7 =3.0). The scores of married adult patients with epilepsy on QOLIE (61.8 ± 15.3) and social function (70.9 ± 22.7) were higher than the scores of the unmarried patients aged between 20 and 44 years. The scores of married adult epileptics on the QOLIE (58.4 ± 14.6) and the energy/fatigue (62.1 ± 20.4) were higher than the scores of the unmarried patients (QOLIE = 58.4 ± 14.6 and the energy/fatigue = 62.1 ± 20.4) aged between 45 and 59 years. For the adult epilepsy patients, depression, anxiety, seizures within the last year, disease course, medical expense category, and marriage* age are negatively correlated with the quality of life. Occupation, educational level, and average monthly income are closely related to the quality of life. CONCLUSIONS: Married adult epileptic patients have better quality of life than that of unmarried adult patients in young and middle-aged age groups. Unmarried adult patients with epilepsy are more anxious and depressed than married adult patients.

A meta-analysis of the success rates of heartbeat restoration within the platinum 10 min among outpatients suffering from sudden cardiac arrest in China.

BACKGROUND: The optimal time to save a person who has had a sudden cardiac arrest is within the first few minutes of the incident. Early compression and early defibrillation should be performed at this time. Timeliness is the key to successful CPR; as such, Prof. He proposed the "platinum 10 min" system to study early CPR issues. This paper systematically evaluates the success rates of heartbeat restoration within the "platinum 10 min" among patients suffering from sudden cardiac arrest. METHODS: The clinical data of outpatients suffering from a cardiac arrest were retrieved from the China Knowledge Network (January 1975-January 2015), the Chongqing VIP database (January 1989-January 2015), and the Wanfang database (January 1990-January 2015). The success of the cardiopulmonary resuscitation (CPR) performed at different times after the patients had cardiac arrests was analyzed. Two researchers screened the literature and extracted the data independently. A meta-analysis was conducted using Stata12.0. A total of 57 papers met the inclusion criteria, including 29,269 patients. Of these patients, 1776 had their heartbeats successfully restored. The results showed high heterogeneity (X (2) = 3428.85, P < 0.01, I(2) = 98.4 %). The meta-analysis was conducted using a random-effects model. The combined effect size was 0.171 (0.144-0.199). RESULTS: (1) The success rate of heartbeat restoration did not differ among the four emergency treatment methods that patients received: the methods described in the 2000 Guidelines for CPR and Emergency Cardiovascular Care, that described in the 2005 version, 2010 version, and another CPR method. (2) The patients were divided into five groups based on the time when CPR was performed: the ≤1 min group, the 1- ≤ 5 min group, the 5- ≤ 10 min group, the 10- ≤ 15 min group and the >15 min group. The CPR success rates of these five groups were 0.247 (0.15-0.344), 0.353 (0.250-0.456), 0.136 (0.109-0.163), 0.058 (0.041-0.075), and 0.011 (0.004-0.019), respectively. The CPR success rates did not differ between the patients in the ≤1 min group and the 1- ≤ 5 min group. This success rate was higher for the patients in the 1- ≤ 5 min group than those in the 10- ≤ 15 min group, those in the 10- ≤ 15 min group, and those in the >15 min group. The CPR success rate was higher for the patients in the 5-10 min group than those in the 10- ≤ 15 min group and those in the >15 min group. CONCLUSIONS: The CPR success rate was higher for the patients in the 10- ≤ 15 min group than those in the >15 min group. In addition, the patients were divided into two groups based on whether CPR was performed within the first 10 min after the cardiac arrest occurred: the ≤10 min group and the >10 min group. The CPR success rate was higher for the patients in the ≤10 min group (0.189 [0.161-0.218]) than those in the >10 min group (0.044 [0.032-0.056]). (3) Differences were not found between the CPR success rates among the patients in the telephone guidance group (0.167 [0.016-0.351]) and those in the ≤1 min, 1- ≤ 5 min, 5- ≤ 10 min, 10- ≤ 15 min, and >15 min groups. (4) The CPR success rates did not differ among in the patients in the witness + public group (0.329 [0.221-0.436]), those in the ≤1 min group, and those in the 1- ≤ 5 min group. However, this success rate was higher in the patients in the witness + public group than those in the 5- ≤ 10 min, 10- ≤ 15 min, and >15 min groups. CONCLUSIONS: The success rate of heartbeat restoration did not differ among patients receiving CPR based on different guidelines. The success rate of CPR lies in its timeliness. The participation of the general population is the cornerstone of improving CPR. Providing complete emergency treatment equipment and perfecting comprehensive measures can improve the success rate of CPR among patients within the platinum 10 min. CPR research in China must be improved.

Influence of Occupational Status on the Quality of Life of Chinese Adult Patients with Epilepsy.

BACKGROUND: Epilepsy is one of the most common serious neurological disorders. The present study aimed to investigate the influence of occupational status on the quality of life of Chinese adult patients with epilepsy. METHODS: This study surveyed 819 subjects clinically diagnosed with epilepsy for more than 1 year in 11 hospitals in Beijing; 586 were employed (71.55%). All subjects completed the case report form with inquiries on demographic data, social factors, and illness. The patients' quality of life was assessed using the quality of life in patients with epilepsy-31 items (QOLIE-31) questionnaire. RESULTS: The QOLIE-31 score in the employed group was significantly higher than that in the unemployed group. Furthermore, the scores in all the sections (overall quality of life, energy/fatigue, emotional well-being, seizure worry, cognition, social function, and medication effects) of the employed group were higher than those of the unemployed group. Both the employed and unemployed groups achieved the highest difference in social function. The QOLIE-31 score of students was higher than those of farmers and workers. Both the students and workers scored higher in the quality of life compared with the adult peasants living with epilepsy. The students and farmers showed significant differences in QOLIE-31 score, cognition, emotional well-being, overall quality of life, energy/fatigue, and social function. In contrast, no significant difference was noted in seizure worry and medication effects across the three different kinds of occupation. CONCLUSION: Occupational status might affect the quality of life of Chinese adult patients with epilepsy, and social function is the most important contributing factor.

Comparison of Positron Emission Tomography Using 2-[18F]-fluoro-2-deoxy-D-glucose and 3-deoxy-3-[18F]-fluorothymidine in Lung Cancer Imaging.

BACKGROUND: The detection of solitary pulmonary nodules (SPNs) that may potentially develop into a malignant lesion is essential for early clinical interventions. However, grading classification based on computed tomography (CT) imaging results remains a significant challenge. The 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography (PET)/CT imaging produces both false-positive and false-negative findings for the diagnosis of SPNs. In this study, we compared 18F-FDG and 3-deoxy-3-[18F]-fluorothymidine (18F-FLT) in lung cancer PET/CT imaging. METHODS: The binding ratios of the two tracers to A549 lung cancer cells were calculated. The mouse lung cancer model was established (n = 12), and micro-PET/CT analysis using the two tracers was performed. Images using the two tracers were collected from 55 lung cancer patients with SPNs. The correlation among the cell-tracer binding ratios, standardized uptake values (SUVs), and Ki-67 proliferation marker expression were investigated. RESULTS: The cell-tracer binding ratio for the A549 cells using the 18F-FDG was greater than the ratio using 18F-FLT (P < 0.05). The Ki-67 expression showed a significant positive correlation with the 18F-FLT binding ratio (r = 0.824, P< 0.01). The tumor-to-nontumor uptake ratio of 18F-FDG imaging in xenografts was higher than that of 18F-FLT imaging. The diagnostic sensitivity, specificity, and the accuracy of 18F-FDG for lung cancer were 89%, 67%, and 73%, respectively. Moreover, the diagnostic sensitivity, specificity, and the accuracy of 18F-FLT for lung cancer were 71%, 79%, and 76%, respectively. There was an obvious positive correlation between the lung cancer Ki-67 expression and the mean maximum SUV of 18F-FDG and 18F-FLT (r = 0.658, P< 0.05 and r = 0.724, P< 0.01, respectively). CONCLUSIONS: The 18F-FDG uptake ratio is higher than that of 18F-FLT in A549 cells at the cellular level. 18F-FLT imaging might be superior for the quantitative diagnosis of lung tumor tissue and could distinguish lung cancer nodules from other SPNs.
