The logistic regression model based on clinical and laboratory characteristics was constructed to distinguish COVID-19 from H1N1. Scores were assigned to each of independent discrimination factors based on their odds ratios. The performance of the prediction model and scoring system was assessed. RESULTS: A total of 236 patients were recruited, including 20 COVID-19 patients and 216 H1N1 patients. Logistic regression revealed that age >34 years, temperature ≤37.5℃, no sputum or myalgia, lymphocyte ratio ≥20% and creatine kinase-myocardial band isoenzyme(CK-MB) >9.7 U/L were independent differentiating factors for COVID-19. The area under curves(AUCs) of the prediction model and scoring system in differentiating COVID-19 from H1N1 were 0.988 and 0.962, respectively. CONCLUSIONS: There are certain differences in clinical and laboratory features between patients with COVID-19 and H1N1. The simple scoring system may be a useful tool for the early identification of COVID-19 patients from H1N1 patients.展开更多

Our aim is to detect the risks of multilevel PPH in different cesarean section (CS) groups [including nulliparous CS with indications, nulliparous CS without indications, repeat cesarean (RC), vaginal birth after cesarean (VBAC), cesarean after vaginal birth (CAVB)]. We conducted a retrospective cohort study, and the data on 127 145 women collected from January 2014 to May 2016 and from 35 tertiary hospitals in Shanxi province, China, were reviewed. Based on the measuring results of PPH, an ordered logistic regression model was used to analyze the adjusted PPH risks for each of the CS groups, and comparisons were drawn between them. Finally, a total of 99 066 nulliparous (77.92%) and 28 079 multiparous (22.08%) women were observed. The number of CS cases was 61 117, and the rate for CS was 48.07%. A total of 10 029 women did not show indications for CS and accounted for 16.41% of the CS parturient, whereas 9103 women underwent a repeated cesarean, with a CS frequency of 14.89%. The number of VBAC cases was 989, whose rate was 9.88% in prior CS women. The number (proportions) of PPH was 3658 (2.88%) in L1 (PPH volume: ≥900 and 〈1500 mL), 520 (0.41%) in L2 (PPH volume: ≥1500 and〈2100 mL), and 201 (0.16%) in L3 (PPH volume: ≥2100 mL). The Ln (n= 1, 2, 3, etc.) represented the increasing order of PPH severity. In the adjusted results, compared with spontaneous vaginal delivery (SVD) as the reference group, in the adjusted result for nulliparous, there was a decreased PPH risk in CS with indications (OR: 2.32; CI: 2.04-2.62), which was lower than that of CS without indications (OR: 2.50; CI: 2.01-2.96). The highest PPH risk in all subgroups (i.e. nulliparous and multiparous groups) was observed in the RC (OR: 3.61; CI: 3.16-4.17), which was nearly twice higher than that of the VBAC (OR: 1.82; CI: 1.33-2.52). CAVB (OR: 1.03; CI: 0.65-1.62) showed no significant difference with the reference group. Thus, we deemed that CS should be avoided in nulliparous pregnancies unless indicated, to prevent or reduce the rates for the use of RC or VBAC which are high risks of severe PPH to the parturient women.展开更多

Previous studies showed that TACE combined with recombinant human adenovirus type 5(H101) may provide a clinical survival benefit. In the present study, we aimed to determine the survival benefit of TACE with or without H101 for patients with intermediate to advanced HCC and to develop an e ective nomogram for predicting individual survival outcomes of these patients.Methods: We retrospectively collected data from 590 patients with intermediate to advanced HCC who were treated at Sun Yat?sen University Cancer Center between January 2007 and July 2015. After propensity score matching, 238 patients who received TACE with H101(TACE with H101 group) and 238 patients who received TACE without H101(TACE group) were analyzed. Overall survival(OS) was evaluated using the Kaplan–Meier method; the nomogram was developed based on Cox regression analysis. Discrimination and calibration were measured using the concordance index(c?index) and calibration plots.Results: Clinical and radiologic features were similar between the two groups. OS rates were significantly lower in the TACE group than in the TACE with H101 group(1?year OS rate, 53.8% vs. 61.3%; 2?year OS rate, 33.4% vs. 44.2%; 3?year OS rate, 22.4% vs. 40.5%; all P < 0.05). Multivariate Cox regression analysis for the entire cohort showed that alpha?fetoprotein level, alkaline phosphatase level, tumor size, metastasis, vascular invasion, and TACE with or without H101 were independent factors for OS, all of which were included in the nomogram. Calibration curves showed good agreement between nomogram?predicted survival and observed survival. The c?index of the nomogram for predict?ing OS was 0.716(95% confidence interval 0.686–0.746).Conclusions: TACE plus H101 extends the survival of patients with intermediate to advanced HCC. Our proposed nomogram provides individual survival prediction and stratification for patients with intermediate to advanced HCC who receive TACE with or without H101.展开更多

文摘Postpartum hemorrhage (PPH) is one of the most adverse obstetric outcomes. Our aim is to detect the risks of multilevel PPH in different cesarean section (CS) groups [including nulliparous CS with indications, nulliparous CS without indications, repeat cesarean (RC), vaginal birth after cesarean (VBAC), cesarean after vaginal birth (CAVB)]. We conducted a retrospective cohort study, and the data on 127 145 women collected from January 2014 to May 2016 and from 35 tertiary hospitals in Shanxi province, China, were reviewed. Based on the measuring results of PPH, an ordered logistic regression model was used to analyze the adjusted PPH risks for each of the CS groups, and comparisons were drawn between them.

The highest PPH risk in all subgroups (i.e. nulliparous and multiparous groups) was observed in the RC (OR: 3.61; CI: 3.16-4.17), which was nearly twice higher than that of the VBAC (OR: 1.82; CI: 1.33-2.52). CAVB (OR: 1.03; CI: 0.65-1.62) showed no significant difference with the reference group. Thus, we deemed that CS should be avoided in nulliparous pregnancies unless indicated, to prevent or reduce the rates for the use of RC or VBAC which are high risks of severe PPH to the parturient women.

文摘Background:The optimal strategy for adjuvant therapy after curative resection for hepatocellular carcinoma(HCC)patients with solitary tumor and microvascular invasion(MVI)is controversial.This trial evaluated the efficacy and safety of adjuvant transcatheter arterial chemoembolization(TACE)after hepatectomy versus hepatectomy alone in HCC patients with a solitary tumor≥5 cm and MVI.Methods:In this randomized,open-labeled,phase III trial,HCC patients with a solitary tumor≥5 cm and MVI were randomly assigned(1:1)to receive either 1-2 cycles of adjuvant TACE after hepatectomy(Hepatectomy-TACE)or hepatectomy alone(Hepatectomy Alone).The primary endpoint was disease-free survival(DFS);the secondary end-points included overall survival(OS)and adverse events.Results:Between June 1,2009,and December 31,2012,250 patients were enrolled and randomly assigned to the Hepatectomy-TACE group(n=125)or the Hepatectomy Alone group(n=125).Clinicopathological characteristics were balanced between the two groups.The median follow-up time from randomization was 37.5 months[interquartile range 18.3-48.2 months].The median DFS was significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group[17.45 months(95%confidence interval[CI]11.99-29.14)vs.9.27 months(95%CI 6.05-13.70),hazard ratio[HR]=0.70(95%CI 0.52-0.95),P=0.020],respectively.The median OS was also significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group[44.29 months(95%CI 25.99-62.58)vs.22.37 months(95%CI 10.84-33.91),HR=0.68(95%CI 0.48-0.97),P=0.029].Treatment-related adverse events were more frequently observed in the Hepatectomy-TACE group,although these were generally mild and manageable.The most common grade 3 or 4 adverse events in both groups were neutropenia and liver dysfunction.Conclusion:Hepatectomy followed by adjuvant TACE is an appropriate option after radical resection in HCC patients with solitary tumor≥5 cm and MVI,with acceptable toxicity.
