ABSTRACT

Objective:To investigate CT classification of diffuse idiopathic skeletal hyperostosis (DISH), and to analyze the correlation between the position of ossification in the anterolateral spine and the sagittal configuration of the spine.Methods:The medical records of 109 patients (70 male and 39 female) who underwent whole spine computerized tomography (CT) from October 2018 to October 2020 were retrospectively analyzed. The average age was 68.4±6.9 years old, ranging from 60 to 88 years old. High resolution CT volume rendering technique images were used to assess the degree of anterolateral spinal ossification in each vertebral space, and a CT grading system was established. Sagittal parameters such as thoracic kyphosis (TK), lumbar lordosis(LL), cervical lordosis (CL), sacral slope (SS), and thoracolumbar junction angle (TLJ) of the patients were measured. The sagittal morphology of the spine was divided into four types using the modified Abelin-Genevois (AG) sagittal classification. In AG type 1 patients, the kyphotic vertex was located in the middle of the thoracic spine (T 4-T 11). In AG type 2 patients, there was no significant kyphotic vertex. In AG type 3 patients, the kyphotic vertex was located in the thoracolumbar segment (T 12-L 2). In AG type 4 patients, the kyphotic vertex was located in the upper thoracic segment (T 1-T 3). Inter-observer and intra-observer reliability were calculated by intra-group correlation coefficient ( ICC). Statistical analysis was conducted to investigate the correlation between different AG types and ossification location and severity. Results:The new DISH grading system classifies the severity of anterolateral spinal ossification in each intervertebral space into grades 0 to 3 with an intra-observer ICC value of 0.871 and inter-observer ICC value of 0.874. Combined with Resnick's DISH diagnostic criteria, 97 patients (89.0%) in this study had four consecutive intervertebral spaces with ossification grade 1 or above. For these patients, in T 4-T 11, the standardized ossification grade of AG type 1 was 1.24±0.69, greater than that of AG type 2 (0.84±0.71) and AG type 3 (1.00±0.70), and the differences were statistically significant ( F=23.101, P<0.001). In T 12-L 2, the standardized ossification grade of AG type 3 was 1.44±0.87, which was higher than AG type 1 (1.06±0.84) and AG type 2 (0.72±0.63), the differences were statistically significant ( F=14.008, P<0.001). In this study, no patients with kyphosis apex in the cervicothoracic region (AG type4) were found. In T 1-T 3, there was no statistical difference between the three groups ( F=0.303, P=0.738); in the whole thoracic and lumbar spine (T 1-L 5), there was statistically significant difference in the total ossification grade ( F=14.374, P<0.001), there was no statistical difference between AG type 1 and AG type 3 ( P=0.254), both of which were higher than AG type 2 ( P<0.001). Conclusion:The new DISH ossification grading system proposed in this study has high credibility, which can be used in DISH's study. This study confirmed that the region where the apex of kyphosis is located is prone to anterolateral ossification of the spine.

ABSTRACT

Objective:To analyze the effectiveness and annual cost-effectiveness of extracorporeal cardiopulmonary resuscitation, ECPR) in adults.Methods:Totally 60 patients received ECPR from April 2015 to March 2020 in Emergency Medicine Department of the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. The patients were grouped by discharge survival/hospital death and shockable/unshockable initial rhythm. Age, gender, initial rhythm, survival rate, ECMO treatment time, time-to-death, length of stay and hospitalization costs were analyzed. All discharged survivors were followed up for 1 year, then cost-effectiveness analysis was performed using total cost of ECPR as the cost and 1-year survival rate as the effect.Results:Fifty-four adult patients with ECPR were enrolled, and 17 (31.5%) patients survived and discharged, of whom 15 (88.2%) patients had good neurological outcomes and survived at 1-year follow-up. The median ECMO time was 5 ( IQR 1-8) d, time-to-death was 4 ( IQR 1-9) d, length of stay was 10 ( IQR 3-18) d, total hospitalization cost was 209 122 ( IQR 121 431-303 822) RMB, and the daily cost was 23 587 ( IQR 13 439-38 217) RMB. The rate of shockable initial rhythm was significantly higher in the discharge survival group than the hospital death group. The survival rate of ECPR patients with shockable initial rhythm was significantly higher than that of patients with unshockable initial rhythm, and there was no difference in cost. Conclusions:ECPR is a resource-intensive treatment with a total cost of about 200 000 RMB. Moreover, the effectiveness and annual cost-effectiveness are superior for patients with shockable initial rhythm.

ABSTRACT

Objective:To summarize the clinical characteristics and influencing factors on clinical outcome of patients receiving extracorporeal cardiopulmonary resuscitation (ECPR).Methods:A total of 78 patients receiving ECPR admitted to the Department of Emergency Medicine of the First Affiliated Hospital of Nanjing Medical University (Jiangsu Provincial People’s Hospital) from March 2015 to December 2020 were retrospectively enrolled. Patients were divided into the survival group and death group according to clinical outcome. Their baseline data, CPR associated parameters, and pre-ECPR laboratory tests were compared between the two groups.Results:Of the 78 included patients, 51 patients were male and 27 female. Twenty-three patients finally survived, including 10 males and 13 females. There were no significant differences in age, body mass index and underlying diseases (hypertension, diabetes and coronary heart disease) between the two groups (all P > 0.05). The proportion of male patients in the survival group was lower than that in the death group ( P=0.017). Meanwhile Survival After Veno-Arterial ECMO (SAVE) score was significantly higher in the survival group than that in the death group[ (-1.57±4.15) vs. (-9.36±5.36), P<0.001]. The proportion of by-stander CPR in the survival group was higher than that in the death group ( P=0.014). The pre-ECPR serum AST, ALT, and Cr levels in the survival group were significantly lower than those in the death group (all P<0.05). Logistic regression analysis showed that by-stander CPR ( OR=0.114, 95% CI: 0.015~0.867, P=0.036) and SAVE score ( OR=0.625, 95% CI: 0.479~0.815, P=0.001) were independent risk factors predicting ICU death in patients receiving ECPR. Conclusions:ECPR is an efficient tool to improve clinical outcomes of patients with cardiac arrest. By-stander CPR and SAVE score are independent risk factors predicting ICU death in patients receiving ECPR.

ABSTRACT

Objective:To analyze the early volume characteristics of patients with severe cardiogenic shock treated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and the relationship between their early volume and the prognosis.Methods:This study reviewed patients of Emergency Medical University , treated with VA-ECMO and screened the patients with severe cardiogenic shock and VA-ECMO running more than 72 h for further study. The basic condition of the patients was recorded, and the fluid balance in the first 72 h was analyzed. The patients were grouped according to their fluid balance in the first 72 h. The gender, age, survival rate, continuous renal replacement therapy (CRRT) rate, intra-aortic balloon pump (IABP) rate, and invasive mechanical ventilation rate were compared between the two groups, and the relative risk to the prognosis was calculated. The prognosis was compared between the two groups. Results:Totally 77 patients with severe cardiogenic shock were enrolled. Forty-one cases survived, with an overall survival rate of 53.2%. The volume balance at 48-72 h and the total volume balance at the first 72 h were different between the survival and dead groups. Compared with the positive balance group, patients in the negative balance group were less likely to receive CRRT or invasive mechanical ventilation during the first 72 h. Patients in the negative balance group during the first 72 h had a better survival rate, and their relative risk of survival was 1.81 (95% confidence interval: 1.101, 2.985). However, there was no significant difference in survival rate according to every 24 h fluid balance.Conclusions:Patients with severe cardiogenic shock treated with VA-ECMO who had negative total volume balance during the first 72 h are more likely to survive and less likely to require CRRT or invasive mechanical ventilation.

ABSTRACT

Objective:To study the application of blood products in patients with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and evaluate its effect on the prognosis.Methods:A total of 83 adult patients treated with VA-ECMO in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University from January 2017 to January 2020 were grouped by survival to explore the risk factors of 28-day mortality using binary logistic regression, and the threshold was calculated by ROC curve.Results:Platelet transfusion ( OR=2.506, 95% CI: 1.142-5.499) and non-myocarditis disease ( OR=6.881, 95% CI: 1.615-29.316) were the risk factors of 28-day mortality in adult VA-ECMO patients. The threshold of platelet transfusion was 0.427 mL/(kg·d) (sensitivity 78.4%, specificity 69.6% , AUC 0.735). Conclusions:The increased platelet transfusion is related to the poor prognosis of adult patients with VA-ECMO. Refractory myocarditis patients are better treated with VA-ECMO.

ABSTRACT

Objective:To summarize the clinical experience of extracorporeal membrane oxygenation (ECMO) support in acute myocardial infarction (AMI) complicated by cardiogenic shock.Methods:Thirty-seven AMI patients received ECMO from March 2016 to October 2020 in Emergency Department of the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. Gensini score was used to evaluate the coronary lesion severity, vasoactive-inotropic score (VIS) was used to assess the usage of vasoactive-inotropic drugs, and cumulative fluid balance (CFB) was used to calculate the fluid balance status, respectively. According to the infarct-related artery, positive/negative fluid balance, and survival/death outcome, the patients were divided into the negative and positive fluid balance groups, and the survival and death groups, respectively. The relationship between Gensini score, 24-hVIS, CFB and patient outcome was analyzed.Results:Thirty AMI-ECMO patients were enrolled, 12 patients survived and 18 died with a mortality rate of 60.0%, and 80.0% of the infarct-related artery were left main and proximal left anterior descending artery. The Gensini score was 77 (52, 120), 24-h VIS 50.0 (31.1, 80.4), daily fluid volume 28.7 (26.6, 34.4) mL/(kg·d), and CBF -1.8 (-9.7, 8.0) mL/kg. The mortality and 24-h VIS of the negative fluid balance group were significantly lower than those of the positive fluid balance group, and the Gensini score, 24-h VIS and CBF of the survival group were significantly lower than those of the death group.Conclusions:LM and pLAD are the most common infarct-related arteries in AMI-ECMO patients, the Gensini score and 24-h VIS have a certain prognostic value, and early negative fluid balance may improve the survival rate.

ABSTRACT

OBJECTIVE: To analyze the active surveillance results of occupational pneumoconiosis(hereinafter referred to as “pneumoconiosis”) in Beijing in 2019. METHODS: A total of 2 634 dust exposed workers were recruited as the active surveillance subjects by judgment sampling method. The abnormalities and influencing factors of High kV or digital photography of posterior-anterior chest radiography(hereinafter referred to as “chest radiography”) and lung function were analyzed. RESULTS: The detection rate of abnormal chest radiograph and pulmonary dysfunction were 14.0%(368/2 634) and 6.6%(175/2 634), respectively. The multivariate logistic regression analysis showed that the risk of abnormal chest radiograph in dust-exposed workers increased with age(P<0.01). Mining and construction workers had higher risk of abnormal chest radiograph than manufacturers(all P<0.05). The risk of abnormal chest radiograph of dusk-exposed workers in state-owned and foreign enterprises was higher than that of workers in private enterprises(P<0.05). The risk of pulmonary dysfunction was increased with age and length of dust exposure(all P<0.05). Workers exposed to silica dust and aluminum dust had higher risks than those exposed to welding dust(all P<0.01). The risk of pulmonary dysfunction of workers in small and micro enterprises was higher than that of workers in large enterprises(all P<0.01). Mining workers had higher risks of pulmonary dysfunction than manufacturing workers(P<0.05). CONCLUSION: Age, length of dust exposure, dust type, industry type, enterprise scale and economic type were the influencing factors of lung injury of dust exposed workers. Therefore, the supervision of key population and industries should be strengthened to reduce the occurrence of pneumoconiosis.

ABSTRACT

BACKGROUND@#Asymptomatic or symptomatic infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be followed by reinfection. The protection conferred by prior infection among coronavirus disease 2019 (COVID-19) patients is unclear. We assessed the incidence of SARS-CoV-2 reinfection and the protection effect of previous infection against reinfection.@*METHODS@#We searched PubMed, EMBASE, Cochrane, Scopus, Web of Science, and ClinicalTrials.gov for publications up until the end date of May 1, 2021. The reinfection rate of recovered patients and the protection against reinfection were analyzed using meta-analysis.@*RESULTS@#Overall, 19 studies of 1096 reinfection patients were included. The pooled reinfection rate was 0.65% (95% confidence interval [CI] 0.39-0.98%). The symptomatic reinfection rate was a bit lower (0.37% [95% CI 0.11-0.78%], I2 = 99%). The reinfection rate was much higher in high-risk populations (1.59% [95% CI 0.30-3.88%], I2 = 90%). The protection against reinfection and symptomatic reinfection was similar (87.02% [95% CI 83.22-89.96%] and 87.17% [95% CI 83.09-90.26%], respectively).@*CONCLUSIONS@#The rate of reinfection with SARS-CoV-2 is relatively low. The protection against SARS-CoV-2 after natural infection is comparable to that estimated for vaccine efficacy. These data may help guide public health measures and vaccination strategies in response to the COVID-19 pandemic. High-quality clinical studies are needed to establish the relevant risk factors in recovered patients.

ABSTRACT

BACKGROUND@#Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease.@*OBJECTIVE@#This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m@*MAIN OUTCOME MEASURES@#The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment.@*RESULTS@#A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group.@*CONCLUSION@#SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone.@*TRIAL REGISTRATION NUMBER@#NCT02063100 on ClinicalTrials.gov.

ABSTRACT

BACKGROUND@#The global pandemic coronavirus disease 2019 (COVID-19) has become a major public health problem and presents an unprecedented challenge. However, no specific drugs were currently proven. This study aimed to evaluate the comparative efficacy and safety of pharmacological interventions in patients with COVID-19.@*METHODS@#Medline, Embase, the Cochrane Library, and clinicaltrials.gov were searched for randomized controlled trials (RCTs) in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)/SARS-CoV. Random-effects network meta-analysis within the Bayesian framework was performed, followed by the Grading of Recommendations Assessment, Development, and Evaluation system assessing the quality of evidence. The primary outcome of interest includes mortality, cure, viral negative conversion, and overall adverse events (OAEs). Odds ratio (OR) with 95% confidence interval (CI) was calculated as the measure of effect size.@*RESULTS@#Sixty-six RCTs with 19,095 patients were included, involving standard of care (SOC), eight different antiviral agents, six different antibiotics, high and low dose chloroquine (CQ_HD, CQ_LD), traditional Chinese medicine (TCM), corticosteroids (COR), and other treatments. Compared with SOC, a significant reduction of mortality was observed for TCM (OR = 0.34, 95% CI: 0.20-0.56, moderate quality) and COR (OR = 0.84, 95% CI: 0.75-0.96, low quality) with improved cure rate (OR = 2.16, 95% CI: 1.60-2.91, low quality for TCM; OR = 1.17, 95% CI: 1.05-1.30, low quality for COR). However, an increased risk of mortality was found for CQ_HD vs. SOC (OR = 3.20, 95% CI: 1.18-8.73, low quality). TCM was associated with decreased risk of OAE (OR = 0.52, 95% CI: 0.38-0.70, very low quality) but CQ_HD (OR = 2.51, 95% CI: 1.20-5.24) and interferons (IFN) (OR = 2.69, 95% CI: 1.02-7.08) vs. SOC with very low quality were associated with an increased risk.@*CONCLUSIONS@#COR and TCM may reduce mortality and increase cure rate with no increased risk of OAEs compared with standard care. CQ_HD might increase the risk of mortality. CQ, IFN, and other antiviral agents could increase the risk of OAEs. The current evidence is generally uncertain with low-quality and further high-quality trials are needed.

ABSTRACT

Objective: To investigate the hepatorenoprotective effects of Origanum vulgare L. against finasteride-induced oxidative injury in the liver and kidney of mice. Methods: Liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI/MS) analysis was utilized to yield a fingerprint of Origanum vulgare polyphenolic constituents. Thirty BALB/c mice received 0.5 mL/day distilled water, finasteride (25 mg/kg/day for 10 d), and 100, 200, or 400 mg/kg/day finasteride + Origanum vulgare extract with 6 mice per group for five weeks. On day 36, liver and kidney function as well as pro- and anti-inflammatory (IFN-γ, IL-12, IL-6, TNF-α, IL-1β, and IL-10) cytokines were measured. The total antioxidant status, nitric oxide (NO), and malondialdehyde levels as well as the activities of NO synthase and catalase were also evaluated. Histopathological study was conducted to assess the effect of Origanum vulgare extract on finasteride-induced renal and hepatic toxicities. Results: Twenty-five major polyphenolic compounds were identified in the Origanum vulgare extract by LC-ESI/MS. Origanum vulgare extract, especially at 200 and 400 mg/kg/day doses, significantly improved liver and kidney biochemical indices, decreased inflammatory cytokines, increased total antioxidant status and NO synthase and catalase activities, as well as decreased plasma NO and malondialdehyde levels in a dose-dependent manner as compared to the finasteride group. Histopathological results further confirmed the protective effect of Origanum vulgare extract. Conclusions: Origanum vulgare extract ameliorates finasteride-induced hepatic and renal biochemical and histopathological alterations, and restores antioxidant/oxidant balance.

ABSTRACT

Three cancer cell lines including gastric cancer SGC-7901, HGC-27, and MGC-803 cells were employed to evaluate the bioactivity of seven Dendrobium species. Simultaneously, these Dendrobium species were assessed with UPLC-Q-TOF-MS, and 504 common peaks were found. Based on the hypothesis that biological effects varied with differences in components, multivariate relevance analysis for chemical component-activity relationship of Dendrobium, including grey relation(GRA) and partial least squares(PLS) analysis were performed to evaluate the contribution of each identified component. The target peaks were identified by standards toge-ther with databases of Dendrobium, Nature Chemistry, MassBank, etc. Finally, four active components, including 3,5,9-trihydroxy-23-methylergosta-7,22-dien-6-one, diacylglycerol(14∶1/22∶6/0∶0), pipercitine, and 22-tricosenoic acid, might have negative effect on the growth of gastric cancer cells.

ABSTRACT

In this experiment, ultra high performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to analyze and identify chemical constituents of Ginseng-Douchi(GD) compound fermentation, and explore the conversion rules of ginsenosides and soybean isoflavones after compound fermentation. Waters Acquity UPLC BEH C_(18) column(2.1 mm×100 mm, 1.7 μm) was adopted, with 0.1% formic acid aqueous solution(A)-0.1% formic acid acetonitrile solution(B) as mobile phase for gradient elution; electrospray ion source(ESI) was used to collect data in positive and negative ion modes; according to the exact mass number, the secondary spectrum comparison of the database and the existing literature reports, Peakview 2.0/masterview 1.0 software was used to determine the common ion structure formula. Finally, a total of 133 chemical constituents were analyzed and identified from the GD. Ginseng saponins and isoflavone glycosides were significantly converted after fermentation. Among them, peak areas of prototype ginsenosides Rk_3, Rh_1, Rh_2, Rh_3, daidzin, glycitin and genistin decreased significantly; whereas peak areas of se-condary ginsenoside Rb_1, Rb_2, Rk_1, glycitein, genistein and daidzein increased significantly. In this experiment, liquid-mass spectrometry technique was used to investigate the conversion of active ingredients of GD compound fermented products after co-fermentation, so as to provide a scientific basis for elucidating pharmacodynamics material basis and quality control.

ABSTRACT

Background@#At the end of 2019, a novel coronavirus outbreak emerged in Wuhan, China, and its causative organism has been subsequently designated the 2019 novel coronavirus (2019-nCoV). The virus has since rapidly spread to all provinces and autonomous regions of China, and to countries outside of China. Patients who become infected with 2019-nCoV may initially develop mild upper respiratory tract symptoms. However, a significant fraction of these patients goes on to subsequently develop serious lower respiratory disease. The effectiveness of adjunctive glucocorticoid therapy uses in the management of 2019-nCoV infected patients with severe lower respiratory tract infections is not clear, and warrants further investigation.@*Methods@#The present study will be conducted as an open-labelled, randomised controlled trial. We will enrol 48 subjects from Chongqing Public Health Medical Center. Each eligible subject will be assigned to an intervention group (methylprednisolone via intravenous injection at a dose of 1-2mg/kg/day for 3 days) or a control group (no glucocorticoid use) randomly, at a 1:1 ratio. Subjects in both groups will be invited for 28 days of follow-up which will be scheduled at 4 consecutive visit points. We will use the clinical improvement rate as our primary endpoint. Secondary endpoints include the timing of clinical improvement after intervention, duration of mechanical ventilation, duration of hospitalization, overall incidence of adverse events, as well as rate of adverse events at each visit, and mortality at 2 and 4 weeks.@*Discussion@#The present coronavirus outbreak is the third serious global coronavirus outbreak in the past two decades. Oral and parenteral glucocorticoids have been used in the management of severe respiratory symptoms in coronavirus-infected patients in the past. However, there remains no definitive evidence in the literature for or against the utilization of systemic glucocorticoids in seriously ill patients with coronavirus-related severe respiratory disease, or indeed in other types of severe respiratory disease. In this study, we hope to discover evidence either supporting or opposing the systemic therapeutic administration of glucocorticoids in severe coronavirus disease 2019 (COVID-19) patients.@*Trial registration@#ClinicalTrials.gov, ChiCTR2000029386, http://www.chictr.org.cn/showproj.aspx?proj=48777.

ABSTRACT

Objective@#To evaluate the effects of incretin-based therapies on body weight as the primary outcome, as well as on body mass index (BMI) and waist circumference (WC) as secondary outcomes.@*Methods@#Databases including Medline, Embase, the Cochrane Library, and clinicaltrials.gov (www.clinicaltrials.gov) were searched for randomized controlled trials (RCTs). Standard pairwise meta-analysis and network meta-analysis (NMA) were both carried out. The risk of bias (ROB) tool recommended by the Cochrane handbook was used to assess the quality of studies. Subgroup analysis, sensitivity analysis, meta-regression, and quality evaluation based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) were also performed.@*Results@#A total of 292 trials were included in this study. Compared with placebo, dipeptidyl-peptidase IV inhibitors (DPP-4Is) increased weight slightly by 0.31 kg [95% confidence interval ( ): 0.05, 0.58] and had negligible effects on BMI and WC. Compared with placebo, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) lowered weight, BMI, and WC by -1.34 kg (95% : -1.60, -1.09), -1.10 kg/m (95% : -1.42, -0.78), and -1.28 cm (95% : -1.69, -0.86), respectively.@*Conclusion@#GLP-1 RAs were more effective than DPP-4Is in lowering the three indicators. Overall, the effects of GLP-1 RAs on weight, BMI, and WC were favorable.

ABSTRACT

Objective:To take a broad overview of the current allocation of diagnosis and treatment resources and management for patients with tuberculous meningitis (TBM) in 49 hospitals in China.Methods:A cross-sectional survey about TBM was carried out in 49 hospitals from 27 provinces across China, by means of electronic questionnaire.The electronic questionnaire was filled by doctors in charge of the departments where TBM patients were routinely admitted from September to December 2018. The availability of medical resources, diagnosis, evaluation, treatment and surveillance in these hospitals were analyzed from the questionnaire. The count data were expressed as percentage.Results:Among the 49 participating hospitals, 37(75.5%) hospitals had less than 50 admissions of suspected TBM per year. Less than 20 TBM patients were confirmed by etiological diagnosis per year in 42(85.7%) participating hospitals.The availability of conventional medical imaging including computed tomography (CT), magnetic resonance imaging (MRI), enhanced MRI, cerebral angiography and magnetic resonance angiography (MRA) were 100.00%(49/49), 95.92%(47/49), 91.84%(45/49), 61.22%(30/49) and 67.35%(33/49), respectively. The rate of access to classic etiological diagnostic methods including acid-fast bacilli smear, mycobacterial culture and T cell spot test of tuberculosis infection were 77.55%(38/49), 95.92%(47/49) and 83.67%(41/49), respectively. Rifampin (100.0%, 49/49), isoniazid (100.0%, 49/49), pyrazinamide (98.0%, 48/49) and ethambutol (95.9%, 47/49) were most commonly used in initial anti-tuberculosis treatment of non-severe patients with TBM. The course of anti-tuberculosis treatment was 18 months in 25(51.0%) hospitals, and 12 months in 17(34.7%) hospitals. Intrathecal glucocorticoid and isoniazid were used in 39(79.6%) hospitals. Dexamethasone was used as part of treatment in 24(49.0%) hospitals, and the duration of glucocorticoid was about two months in 28(57.1%) hospitals. As for hyponatremia, 32(65.3%) hospitals didn′t investigate the cause, and hypertonic saline (83.7%, 41/49) and oral rehydration salts (71.4%, 35/49) were considered as the most common treatment strategy. Lumbar puncture was most commonly used for intracranial pressure surveillance in 48(98.0%) hospitals.Conclusions:The TBM cases admitted to the investigation hospitals are characterized by scattered sources and few confirmed cases of etiology. There are obvious heterogeneities in the diagnosis and treatment of TBM and the management of complications.The standardized plan for diagnosis and treatment of TBM are needed to improve the management.

ABSTRACT

Objective:To explore the changing trend of cardiac troponin T (cTnT) in patients with cardiogenic shock (CS) receiving veno-arterial extracorporeal membrane oxygenation (V-A ECMO) and its predictive value.Methods:A retrospective study was conducted. The data of patients with CS receiving V-A ECMO admitted to the First Affiliated Hospital of Nanjing Medical University from March 2015 to May 2020 were enrolled. The baseline data, ECMO related parameters, serum cTnT levels at 1, 2, 3 days after ECMO and intensive care unit (ICU) prognosis were recorded. The parameters with clinical significance and significant difference in univariate analysis were analyzed by binary multivariate Logistic regression analysis. Meanwhile, receiver operating characteristic (ROC) curve was drawn, area under ROC curve (AUC) was analyzed, and the threshold, sensitivity and specificity of serum cTnT level and its reduction rate for predicting clinical outcome were evaluated.Results:A total of 72 patients were enrolled, of which 42 survived and 30 died at ICU discharge, and the ICU mortality was 41.7%. Univariate analysis results: compared with the survival group, the patients in the death group had higher acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score [32 (30, 34) vs. 29 (25, 30)], and the incidence of cardiac arrest before ECMO (70.0% vs. 31.0%), the ratios of invasive mechanical ventilation and continuous renal replacement therapy during ECMO were higher (96.7% vs. 66.7%, 83.3% vs. 42.9%), and the differences were statistically significant (all P < 0.05). Serum cTnT levels (ng/L) at 2 days and 3 days after ECMO in the death group were significantly higher than those in the survival group [2 days: 6 373.5 (898.3, 15 251.5) vs. 1 760.5 (933.0, 4 257.8), 3 day: 6 202.0 (758.9, 16 554.3) vs. 1 678.0 (623.3, 3 407.8), both P < 0.05], and the decrease rates of cTnT within 2 days and 3 days after ECMO were significantly lower than those in the survival group [2 days: 17.3% (-44.2%, 34.7%) vs. 36.8% (18.1%, 60.6%), 3 days: 32.4% (-30.0%, 55.5%) vs. 53.2% (38.3%, 72.3%), both P < 0.05]. Binary multivariate Logistic regression analysis showed that cardiac arrest before ECMO [odds ratio ( OR) = 4.564, 95% confidence interval (95% CI) was 1.212-17.193, P = 0.025] and the decrease rate of cTnT level within 2 days after ECMO ( OR = 1.617, 95% CI was 1.144-4.847, P = 0.026) were independent prognostic risk factors for the ICU death of CS patients receiving V-A ECMO. ROC curve analysis showed that the decline rate of cTnT within 2 days after ECMO transfer had a certain predictive value for the ICU death of CS patients receiving V-A ECMO. The AUC was 0.704 (95% CI was 0.584-0.824). The optimal diagnostic threshold was 40.0%, the sensitivity was 86.7%, the specificity was 52.4%, the positive predictive value was 66.9%, and the negative predictive value was 89.1%. Conclusions:The early decline rate of cTnT in CS patients who received V-A ECMO treatment in death group was lower than that of survival patients. The cTnT decline rate 2 days after ECMO was an independent risk factor for the death of such patients.

ABSTRACT

Objective:To investigate the status of regional citrate anticoagulation (RCA) in continuous renal replacement therapy (CRRT) in emergency department.Methods:Participants of a national emergency conference from August 1st to August 4th in 2019 from hospitals of different levels in different regions were interviewed by online questionnaire to collect data about the current status and limitations of the application of RCA in emergency CRRT by convenient sampling.Results:Totally 407 questionnaires were collected through internet, and the completeness of the answers was as high as 100%. Twenty-three responses with logic errors were excluded, and 384 questionnaires were finally retrieved, with an effective rate of 94.35%. Representatives from 29 provinces, autonomous regions and municipalities directly under the Central Government participated in the questionnaire survey, and the hospitals in which they worked were mainly class Ⅲ grade A [70.31% (270/384)]. The survey showed that 61.46% (236/384) of the emergency departments could carry out CRRT independently. There were less than 10 CRRT cases per month in most emergency departments [52.87% (166/314)]. In the emergency departments where CRRT were carried out, heparin was a widely used and well-applied anticoagulant [82.17% (258/314)], and 199 emergency departments (63.38%) were proficient in RCA. In clinical practice, heparin [49.68% (156/314)] was preferred to RCA [25.80% (81/314)] and low molecular weight heparin [23.56% (74/384)]. In the emergency departments where RCA could be used skillfully, 4% sodium citrate was the main regional anticoagulant [68.34% (136/199)]. Anticoagulation protocol came from different sources, most of which were from nephrology or dialysis center (29.65%). Most departments could adjust the ionized calcium before the filter to the target safety level [0.9-1.2 mmol/L, 88.94% (177/199)], and adjust the ionized calcium after the filter to the target ideal anticoagulation level [0.2-0.4 mmol/L, 93.47% (186/199)] within 4 hours. The common complications that emergency physicians concerned were accumulation of citrate [58.29% (116/199)], metabolic alkalosis [54.77% (109/199)] and metabolic acidosis [37.19% (74/199)]. In 281 emergency departments that could not use RCA, there were kinds of factors that limited the use of citrate, such as higher cost than heparin (31.67%), unskilled personnel (21.00%), limited source of citrate (17.08%), concerns of complications (11.74%). At present, the substitution fluids used in clinical practice were mainly the commercial products (45.54%). In most cases, emergency CRRT filters had a life span of 12-23 hours (39.49%).Conclusions:The use of RCA in domestic emergency CRRT is low. Compared with the international peers, we are still lacking of adequate understanding of RCA. Therefore, it is necessary to develop an anticoagulation protocol of RCA for emergency departments in China, and promote training of CRRT.

ABSTRACT

Objective:To promote emergency airway management from the perspective of training and to explore the training mode of emergency airway management based on clinical procedures.Methods:Airway management training courses were designed according to the clinical treatment principle centered on patient safety in combination with actual clinical procedures. The course took the CHANNEL process of airway management as the main line and focused on artificial ventilation, oxygen therapy and rapid induction of intubation techniques. During the teaching, we took the clinical handling process as the main line, and adopted methods of equipment display, video presentation and on-site explanation. Courses were freely registered or oriental enrollment. Online questionnaires were used to collect feedback from the students after class and were then analyzed.Results:A total of 15 training sessions were held in 13 cities across the country, with 566 participants, and 185 questionnaire responses were received. About the content of single course, participants thought that the first three parts were difficult to understand, including oxygen therapy (48, 25.9%), CHANNEL process explanation and practice (48, 25.9%) and rapid induction of intubation process (47, 25.4%). After class, 41 participants (22.2%) changed work procedures of emergency airway management, 140 (75.7%) partially changed work procedures of emergency airway management, and 4 (2.2%) still used the original work procedure.Conclusion:The course of emergency airway management based on clinical procedures meets the current clinical needs and can better improve the training of clinical competency.
