Abstract
Objective: To investigate the difference of urinary protein components in pregnant women with pre-eclampsia (PE) with different degrees of proteinuria and the correlation between 24-hour urinary protein quantification and estimated glomerular filtration rate (eGFR). Methods: Clinical data of 101 PE pregnant women who were delivered in Renji Hospital, Shanghai Jiao Tong University School of Medicine from July 2018 to June 2022 were retrospectively analyzed. According to 24-hour urinary protein quantification, they were divided into 3 groups, including 40 cases of mild proteinuria group (24-hour urinary protein quantification ≤2.0 g), 21 cases of moderate proteinuria group (2.0 g<24-hour urinary protein quantification ≤5.0 g), 40 cases of severe proteinuria group (24-hour urinary protein quantification >5.0 g). The general clinical data, urinary protein index and renal function index of PE pregnant women in 3 groups were compared. The eGFR was calculated based on age, serum creatinine (sCr), blood urea nitrogen (BUN) and serum albumin (sAlb). Correlation analysis was conducted between 24-hour urinary protein quantification and each index of eGFR. Results: (1) General clinical data: the median PE onset week (31 weeks) and delivery gestational week [(36.4±3.6) weeks] of PE pregnant women in the mild proteinuria group were later than those in the moderate proteinuria group [median PE onset: 22 weeks, delivery: (32.2±4.2) weeks] and severe proteinuria group [median PE onset: 25 weeks, delivery: (29.6±3.4) weeks]; systolic blood pressure, diastolic blood pressure, alanine aminotransferase, aspartate aminotransferase levels and the incidence of fetal growth restriction were lower than those in the moderate and severe proteinuria groups; median newborn birth weight (3 150 g) was higher than those in the moderate proteinuria group (1 305 g) and the severe proteinuria group (1 042 g), respectively. The differences were statistically significant (all P<0.05). (2) Urinary protein index: the 24-hour urinary protein quantification, urinary microalbumin (mAlb) and urinary transferrin (TRF) levels of PE pregnant women in the mild proteinuria group, moderate proteinuria group and severe proteinuria group were increased successively, and the differences were statistically significant (all P<0.05). The median urinary α1-microglobulin (α1-MG) level of PE pregnant women in the severe proteinuria group (50 mg/L) was significantly higher than those in the mild proteinuria group (17 mg/L) and moderate proteinuria group (22 mg/L; all P<0.05), but there was no significant difference between the mild proteinuria group and the moderate proteinuria group (P>0.05). There was no significant difference in the median urinary β2-microglobulin (β2-MG) level among the 3 groups (P=0.632). (3) Renal function index: sAlb and eGFR of PE pregnant women in the mild proteinuria group, moderate proteinuria group and severe proteinuria group were successively decreased, and BUN was successively increased, respectively, and the differences were statistically significant (all P<0.05). The sCr level of PE pregnant women in the severe proteinuria group was significantly higher than those in the mild proteinuria group and the moderate proteinuria group (all P<0.05), but there was no significant difference between the mild proteinuria group and the moderate proteinuria group (P>0.05). (4) Correlation analysis: the 24-hour urinary protein quantification of PE pregnant women was significantly negatively correlated with eGFR (r=-0.645, P<0.001), and was correlated with the variables sAlb (r=-0.549, P<0.001), sCr (r=0.582, P<0.001) and BUN (r=-0.657, P<0.001) in the eGFR calculation formula. The 24-hour urinary protein quantification were significantly negatively correlated with the gestational weeks of PE onset, gestational weeks of termination of pregnancy and newborn birth weight (all P<0.05). Conclusions: The protein composition in the urine of PE pregnant women with different degrees of proteinuria is not different, but the protein level is significantly different. There is a significant negative correlation between the increase of 24-hour urinary protein quantification and the decrease of eGFR.

Abstract
Objective: To explore the influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.

Abstract
Cisplatin (DDP) is widely used in the chemotherapy of cervical cancer (CC), the fourth most common female malignancy worldwide. However, some patients progress to chemotherapy resistance, which leads to chemotherapy failure, tumor recurrence, and poor prognosis. Therefore, strategies to identify the regulatory mechanisms underlying CC development and increase tumor sensitivity to DDP will help improve patient survival. This research was designed to ascertain the mechanism of EBF1-dependent regulation of FBN1 which promotes chemosensitivity of CC cells. The expression of EBF1 and FBN1 was measured in CC tissues resistant or sensitive to chemotherapy and in DDP-sensitive or -resistant cells (SiHa and SiHa-DDP cells). SiHa-DDP cells were transduced with lentiviruses encoding EBF1 or FBN1 to evaluate the influence of these two proteins on cell viability, expression of MDR1 and MRP1, and cell aggressiveness. Moreover, the interaction between EBF1 and FBN1 was predicted and demonstrated. Finally, to further verify the EBF1/FB1-dependent mechanism of DDP sensitivity regulation in CC cells a xenograft mouse model of CC was established using SiHa-DDP cells transduced with lentiviruses carrying EBF1 gene and shRNA directed to FBN1 EBF1 and FBN1 showed decreased expression in CC tissues and cells, particularly in those resistant to chemotherapy. Transduction of SiHa-DDP cells with lentiviruses encoding EBF1 or FBN1 lead to decreased viability, IC50, proliferation capacity, colony formation ability, aggressiveness, and increased cell apoptosis. We have shown that EBF1 activates FBN1 transcription by binding to FBN1 promoter region. Additionally, it was revealed that FBN1 silencing reversed the promoting effect of EBF1 overexpression on chemosensitivity of CC cells in vivo. EBF1 facilitated chemosensitivity in CC cells by activating FBN1 transcription.

Abstract
Ruptured Sinus of Valsalva aneurysms during pregnancy is rare and presents a threat both to the mother and the fetus. We report a case of ruptured nonsinus of Valsalva aneurysms in a 26-year-old woman diagnosed at 32+4 weeks of gestation. A successful elective lower-segment cesarean section was conducted under general anesthesia. A successful surgical correction of the ruptured aneurysm under cardiopulmonary bypass (CPB) was performed with patch repair after 13 days. A multidisciplinary approach with respect to the pregnant patient's diagnosis, indications, and timing of surgery is necessary in ensuring the best possible outcomes for both the mother and the child.

Abstract
Objective: To explore the influencing factors of health-related quality of life (HRQoL) in patients with knee osteoarthritis, and to analyze the non-surgical treatment of knee osteoarthritis. Methods: Demographic variables, treatment modalities, imaging data, and 12-item short form health survey (SF-12) scores of patients with knee osteoarthritis in orthopedic outpatient departments of five hospitals in Beijing from December 2017 to November 2018 were collected to analyze influencing factors of HRQoL and non-surgical treatment. Results: A total of 2 034 patients were included. There were 530 males (26.1%) and 1 504 females (73.9%), with a mean age of (59.17±10.22) years. In terms of physical quality of life, female patients with knee osteoarthritis had lower physical components summary (PCS) compared with male patients (β=-0.521, P=0.036); patients aged ≥64 years had lower PCS than those aged<55 years (β=-0.636, P=0.026). Patients with an education of more than 12 years had higher PCS than those with less than 10 years (β=1.063, P<0.001). Compared to patients with mild clinical symptoms, the PCS of patients with moderate clinical symptoms was lower (β=-0.860, P=0.002), while the PCS of those with severe clinical symptoms was much lower (β=-1.126, P<0.001). Patients treated with combination therapy had higher PCS than untreated patients (β=0.731, P=0.005). In terms of mental quality of life, compared to patients engaged in sedentary work, the mental components summary (MCS) of patients engaged in mild manual labor jobs was lower (β=-0.712, P=0.015); Compared to patients with a Charson comorbidity index of 0, patients with a Charlson comorbidity index ≥ 2 had lower MCS (β=-1.183, P=0.007). In the past 12 months, 648 (31.9%), 143 (7.0%), 406 (20.0%), 680 (33.4%), 343 (16.9%), 681 (33.5%), 170 (8.4%) patients had used non-steroid anti-inflammatory drugs (NSAIDs), acetaminophen, glucosamine/chondroitin formulations, physical therapy, articular cavity puncture injection, traditional Chinese medicine treatment and exercise therapy, respectively. Total of 451 patients (22.2%) received monotherapy and 889 patients (43.7%) received combination therapy. Conclusions: The major non-surgical treatment methods for patients with knee osteoarthritis in Beijing are NSAIDs, physiotherapy and traditional Chinese medicine. Combination therapy is used more frequently than monotherapy. Physical quality of life is related to gender, age, education, severity of symptoms and treatment, while mental quality of life is related to occupational labor and comorbidities.

Abstract
Background: Epidural analgesia can be associated with high costs and postsurgical risks such as hypotension, despite its widespread use and value in providing opioid-sparing pain management. We tested the hypothesis that liposomal bupivacaine (LB) might be a reliable alternative to epidural analgesia in this real-world study. Objectives: To compare economic outcomes and hypotension incidence associated with use of LB and epidural analgesia for abdominal surgery. Methods: This retrospective analysis identified records of adults who underwent abdominal surgeries between January 2016 and September 2019 with either LB administration or traditional epidural analgesia using the Premier Healthcare Database. Economic outcomes included length of stay, hospital costs, rates of discharge to home, and 30-day hospital readmissions. Secondary outcomes included incidence of postsurgical hypotension and vasopressor use. Subgroup analyses were stratified by surgical procedure (colorectal, abdominal) and approach (endoscopic, open). A generalized linear model adjusted for patient and hospital characteristics was used for all comparisons. Results: A total of 5799 surgical records (LB, n=4820; epidural analgesia, n=979) were included. Compared with cases where LB was administered, cases of epidural analgesia use were associated with a 1.6-day increase in length of stay (adjusted rate ratio [95% confidence interval (CI), 1.2 [1.2-1.3]]; P<.0001) and $6304 greater hospital costs (adjusted rate ratio [95% CI], 1.2 [1.2-1.3]]; P<.0001). Cost differences were largely driven by room-and-board fees. Epidural analgesia was associated with reduced rates of discharge to home (P<.0001) and increased 30-day readmission rates (P=.0073) compared with LB. Epidural analgesia was also associated with increased rates of postsurgical hypotension (30% vs 11%; adjusted odds ratio [95% CI], 2.8 [2.3-3.4]; P<.0001) and vasopressor use (22% vs 7%; adjusted odds ratio [95% CI], 3.1 [2.5-4.0]; P<.0001) compared with LB. Subgroup analyses by surgical procedure and approach were generally consistent with overall comparisons. Discussion: Our results are consistent with previous studies that demonstrated epidural analgesia can be associated with higher utilization of healthcare resources and complications compared with LB. Conclusions: Compared with epidural analgesia, LB was associated with economic benefits and reduced incidence of postsurgical hypotension and vasopressor use.

Abstract
Objective: To screen the different expressed genes between osteosarcoma and normal osteoblasts, and find the key genes for the occurrence and development of osteosarcoma. Methods: The gene expression dataset GSE33382 of normal osteoblasts and osteosarcoma was obtained from Gene Expression Omnibus (GEO) database. The different expressed genes between normal osteoblasts and osteosarcoma were screened by limma package of R language, and the different expressed genes were analyzed by Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis. The protein interaction network was constructed by the String database, and the network modules in the interaction network were screened by the molecular complex detection (MCODE) plug-in of Cytoscape software. The different expressed genes contained in the first three main modules screened by MCODE were analyzed by gene ontology (GO) using the BiNGO module of Cytoscape software. The MCC algorithm was used to screen the top 10 key genes in the protein interaction network. The gene expression and survival dataset GSE39055 of osteosarcoma was obtained from GEO database, and the survival analysis was performed by Kaplan-Meier method. The data of 48 patients with osteosarcoma treated in the First Affiliated Hospital of Fujian Medical University from January 2005 to December 2015 were selected for verification. The expression of STC2 protein in osteosarcoma was detected by immunohistochemical method, and the survival analysis was carried out combined with the clinical data of the patients. Results: A total of 874 different expressed genes were identified from GSE33382 dataset, including 402 down-regulated genes and 472 up-regulated genes. KEGG enrichment analysis showed that different expressed genes were mainly related to p53 signal pathway, glutathione metabolism, extracellular matrix receptor interaction, cell adhesion molecules, folate tolerance, and cell senescence. The top 10 key genes in the interaction network were GAS6, IL6, RCN1, MXRA8, STC2, EVA1A, PNPLA2, CYR61, SPARCL1 and FSTL3. STC2 was related to the survival rate of patients with osteosarcoma (P<0.05). The results showed that the expression of STC2 protein was related to tumor size and Enneking stage in 48 cases of osteosarcoma. The median survival time of 25 cases with STC2 high expression was 21.4 months, and that of 23 cases with STC2 low expression was 65.4 months. The survival rate of patients with high expression of STC2 was lower than that of patients with low expression of STC2 (P<0.05). Conclusions: Bioinformatics analysis can effectively screen the different expressed genes between osteosarcoma and normal osteoblasts. STC2 is one of the important predictors for the prognosis of osteosarcoma.

The proportion of high-risk factors, different body mass index (BMI) and age stratification between early-onset group and late-onset group were compared. Results: (1) Univariate analysis of high-risk factors: the proportions of high-risk factors in early-onset group and late-onset group were compared, and the differences were statistically significant (all P<0.05). Among them, the proportions of primipara and multiple pregnancy in early-onset group were lower than those in late-onset group, while the proportions of pregnant women with advanced age, irregular antenatal examination, obesity, family history of hypertension, pre-eclampsia, diabetes, kidney diseases, immune system diseases and assisted reproductive technology were higher than those in late-onset group. (2) Hierarchical analysis of BMI: the proportion of pregnant women with BMI≥24 kg/m2 in early-onset group [48.2% (2 828/5 872) vs 45.5% (4 177/9 181), respectively; P=0.001] and the proportion of pregnant women with BMI ≥28 kg/m2 in early-onset group [19.5% (1 143/5 872) vs 18.0% (1 656/9 181), respectively; P=0.028] were significantly higher than those in late-onset group. (3) Age stratification analysis: the proportion of pregnant women aged 35-39 years in the early-onset group [21.8% (1 748/8 023) vs 17.5% (2 110/12 068), respectively; P<0.01], the proportion of pregnant women 40-44 years old [6.8% (544/8 023) vs 5.4% (648/12 068), respectively; P<0.01], and the proportion of pregnant women ≥45 years old [0.7% (58/8 023) vs 0.5% (57/12 068), respectively; P=0.021] were significantly higher than those in the late-onset group. (4) Multivariate analysis: advanced age (≥35 years old), multiple pregnancy, irregular antenatal examination or transfer from other hospitals, family history of hypertension (including paternal, maternal and parental lines), previous history of pre-eclampsia, kidney diseases, immune system diseases (systemic lupus erythematosus, antiphospholipid antibody syndrome) and assisted reproductive technology pregnancy were the risk factors affecting the severity of pre-eclampsia (all P<0.05). Conclusion: Pregnant women with high risk factors such as age ≥35 years old, BMI ≥24 kg/m2 before pregnancy, family history of hypertension, history of pre-eclampsia, chronic kidney diseases, immune diseases (mainly including systemic lupus erythematosus and antiphospholipid syndrome) and assisted reproductive technology are more likely to have early-onset pre-eclampsia.

Abstract
Background Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease during pregnancy. Studies of risk factors are of great significance to maternal and fetal outcomes in patients with TOF. Aims To identify predictive risk factors for maternal and perinatal complications in women with TOF. Subjects and Methods 78 patients with TOF who delivered at Shanghai Obstetrical Cardiology Intensive Care Center between January 1993 and December 2017 were retrospective reviewed. A logistic regression model was used to identify risk factors for maternal and perinatal complications. Results There was no maternal death, five patients developed cardiac failure, sustained arrhythmias requiring treatments were recorded among 2 patients. Factors identified for maternal complications included previous cardiac events and oxygen saturation <90%. Oxygen saturation <90% was found to be independent predictor of maternal cardiac complications (RR = 21.455, 95%CI 2.186-210.572, P = 0.009). The perinatal survival rate was 87.18%, there were 52 term deliveries (66.67%). Perinatal poor outcomes include 9 therapeutic abortions (11.54%), 1 neonatal death (1.28%), 16 premature births (20.51%), 18 small for gestational age children (23.08%), 3 neonatal asphyxia (3.85%), and 3 neonatal cardiac malformations (3.85%). Factors identified for perinatal complications included without cardiac surgery, higher hemoglobin values, higher hematocrit values, oxygen saturation <90%, right ventricular hypertrophy, pulmonary stenosis, ventricular septal defect, and pulmonary hypertension. Oxygen saturation <90% was found to be independent predictor of perinatal complications (RR = 8.270, 95%CI 1.374-49.790, P = 0.021). Conclusions Oxygen saturation <90% is associated with maternal and perinatal risks. Women with TOF whose oxygen saturation <90% are not recommended for pregnancy because of high maternal and perinatal complications.

Abstract
Objective: To investigate and analyze the energy metabolism characteristics and the correlation between energy metabolism and the risk of secondary bacterial infection in patients with hepatitis B virus-related chronic liver disease (HBV-CLD). Methods: Data of 183 cases admitted to the Mengchao Hepatobiliary Hospital of Fujian Medical University from November 2017 to November 2020 were retrospectively analyzed. 79 cases of chronic hepatitis B, 51 cases of hepatitis B-related liver cirrhosis, and 53 cases of hepatitis B-related liver failure were collected. Among them patients with liver failure and decompensated liver cirrhosis were defined as severe liver disease group. The Quark RMR indirect calorimetry (COSMED Corporation, Italy) was used to exam the patients' energy metabolism condition, and the incidences of secondary bacterial infection of the patients during hospitalization were recorded. Shapiro-Wilk test and normal QQ plot were used to analyze the normal distribution of continuous variable data, which was consistent with the normal distribution and was described by mean ± standard deviation. In addition, if it did not conform to the normal distribution, the median and interquartile distance were used to describe it. Levene's test was used to test the homogeneity of variance of the data, which was consistent with the normal distribution. The t-test was used to compare the means of the two groups of samples. One-way analysis of variance was used to compare the mean values of the three groups of samples, and then the Tukey's test was used to compare the two groups. If the variance was uneven or did not conform to the normal distribution, the Wilcoxon rank sum test was used to compare the differences between the two groups. Kruskal-Wallis test (H test) was used to compare the differences between the three groups of samples, and then the Dunnett's test (Z test) was used for comparison between the two groups. Categorical variable data were analyzed using chi-square test. Logistic regression analysis was used to screen independent risk factors, and the criteria for variable inclusion (P < 0.05). Results: The respiratory entropy (RQ) and non-protein respiratory entropy (npRQ) of the three groups had statistically significant difference (P < 0.05). Among them, the RQ and npRQ of the chronic hepatitis B group were higher than hepatitis B-related liver cirrhosis group and hepatitis B-related liver failure group. There were statistically significant differences in fat oxidation rate (FAT%) and carbohydrate oxidation rate (CHO%) between the three groups (P < 0.05). Compared with hepatitis B-related liver cirrhosis group and hepatitis B-related liver failure group, chronic hepatitis B group (P < 0.05) had lower FAT% and higher CHO%. There were no statistically significant differences in the measured and predicted resting energy expenditure and protein oxidation rate (PRO%) between the three groups. The incidence of secondary bacterial infection in patients with severe liver disease was 48.39% (45/93). Compared with the non-infected group, the RQ and npRQ values of the infected group were significantly decreased (P < 0.05), while FAT% was significantly increased (P < 0.05). Logistic regression analysis showed that glutamyltransferase, cholesterol, and npRQ were independent risk factors for secondary bacterial infections in patients with severe liver disease. Glutamyltransferase elevation, and cholesterol and npRQ depletion had suggested an increased risk of secondary bacterial infection. Subgroup analysis of patients with hepatitis B-related liver failure also showed that compared with non-infected group, RQ value and npRQ value of secondary bacterial infection group were significantly decreased (P < 0.05), while FAT% was significantly increased (P < 0.05). Conclusion: Patients with hepatitis B virus-related chronic liver disease generally have abnormal energy metabolism. Low RQ, npRQ, CHO% and high FAT% are related to the severity of the disease; while npRQ reduction is related to the risk of secondary bacterial infection in patients with severe liver disease, and thus can be used as a clinical prognostic indicator.

Abstract
Background/Objective: This study evaluated emergency department (ED) visit trends, subsequent inpatient admissions for patients with inflammatory bowel disease (IBD) diagnosis and IBD-related abdominal pain (AP), and hospital-level variation in inpatient admission rates in the USA (US). Methods: This population-based, cross-sectional study included data from Nationwide Emergency Department Sample (NEDS, 2006─2013) database. Patients ≥18 years of age with primary ED diagnosis of IBD/IBD-related AP were included. Variables included demographics, insurance information, household income, Quan-Charlson comorbidity score, ED discharge disposition, and length of hospital stay (2006, 2010, and 2013). Variation between hospitals using risk-adjusted admission ratio was estimated. Results: Annual ED visits for IBD/100,000 US population increased (30 in 2006 vs 42 in 2013, p = 0.09), subsequent admissions remained stable (20 in 2006 vs 23 in 2013, p = 0.52). ED visits for IBD-related AP increased by 71% (7 in 2006 vs 12 in 2013; p = 0.12), subsequent admissions were stable (0.50 in 2006 vs 0.58 in 2013; p = 0.88). Proportion of patients with subsequent hospitalization decreased (IBD: 65.7% to 55.7%; IBD-related AP: 6.9% to 4.9%). Variation in subsequent inpatient admissions was 1.42 (IBD) and 1.96 (IBD-related AP). Conclusions: An increase in annual ED visits was observed for patients with IBD and IBD-related AP; however, subsequent inpatient admission rate remained stable.

Abstract
Background: Approximately 60% of hospitalized children undergoing surgery experience at least 1 day of moderate-to-severe pain after surgery. Pain following spine surgery may affect opioid exposure, length of stay (LOS), and costs in hospitalized pediatric patients. This is a retrospective cohort analysis of pediatric patients undergoing inpatient primary spine surgery. Objectives: To examine the association of opioid-related and economic outcomes with postsurgical liposomal bupivacaine (LB) or non-LB analgesia in pediatric patients who received spine surgery. Methods: Premier Healthcare Database records (January 2015-September 2019) for patients aged 1-17 years undergoing inpatient primary spine surgery were retrospectively analyzed. Outcomes included in-hospital postsurgical opioid consumption (morphine milligram equivalents [MMEs]), opioid-related adverse events (ORAEs), LOS (days), and total hospital costs. A generalized linear model adjusting for baseline characteristics was used. Results: Among 10 189 pediatric patients, the LB cohort (n=373) consumed significantly fewer postsurgical opioids than the non-LB cohort (n=9816; adjusted MME ratio, 0.53 [95% confidence interval (CI), 0.45-0.61]; P<0.0001). LOS was significantly shorter in the LB versus non-LB cohort (adjusted rate ratio, 0.86 [95% CI, 0.80-0.94]; P=0.0003). Hospital costs were significantly lower in the LB versus non-LB cohort overall (adjusted rate ratio, 0.92 [95% CI, 0.86-0.99]; P=0.0227) mostly because of decreased LOS and central supply costs. ORAEs were not significantly different between groups (adjusted rate ratio, 0.84 [95% CI, 0.65-1.08]; P=0.1791). Discussion: LB analgesia was associated with shorter LOS and lower hospital costs compared with non-LB analgesia in pediatric patients undergoing spine surgery. The LB cohort had lower adjusted room and board and central supply costs than the non-LB cohort. These data suggest that treatment with LB might reduce hospital LOS and subsequently health-care costs, and additional cost savings outside the hospital room may factor into overall health-care cost savings. LB may reduce pain and the need for supplemental postsurgical opioids, thus reducing pain and opioid-associated expenses while improving patient satisfaction with postsurgical care. Conclusions: Pediatric patients undergoing spine surgery who received LB had significantly reduced in-hospital postsurgical opioid consumption, LOS, and hospital costs compared with those who did not.

Abstract
OBJECTIVE Effective postsurgical pain management is important for pediatric patients to improve outcomes while reducing resource use and waste. The authors examined opioid consumption and economic outcomes associated with liposomal bupivacaine (LB) or non-LB analgesia use in pediatric patients undergoing cardiothoracic surgery. DESIGN The authors retrospectively analyzed Premier Healthcare Database records. SETTING The data extracted from the database included patient records from hospitals across the United States in both rural and urban locations. PARTICIPANTS The records included data from patients aged 12-to-<18 years. INTERVENTIONS The records belonged to patients undergoing video-assisted thoracoscopic procedures (VATS) who received LB or non-LB analgesia after surgery. MEASUREMENTS AND MAIN RESULTS Outcomes included in-hospital postsurgical opioid consumption in morphine milligram equivalents (MMEs), hospital length of stay (LOS), and total hospital costs; the LB and non-LB cohorts were compared using a generalized linear model with inverse probability of treatment weighting to balance the cohorts. For VATS procedures, pediatric patients receiving LB had significant reductions in in-hospital opioid consumption (632 v 991 MMEs; p < 0.0001), shorter LOS (5.1 v 5.6 days; p = 0.0023), and lower total hospital costs ($18,084 v $21,962; p < 0.0001) compared with those receiving non-LB analgesia. CONCLUSIONS These results support use of LB in multimodal analgesia regimens for managing pain in pediatric patients after cardiothoracic surgery.

Abstract
Objective: To evaluate the effects of neuromuscular exercise therapy on joint stability of knee osteoarthritis (OA) patients. Methods: One hundred and ten patients with knee OA were enrolled in this ongoing prospective cohort study at Arthritis Clinic and Research Center, Peking University People's Hospital from September 2017 to October 2018. The treatment consisted of six-week neuromuscular exercise therapy. The participants were followed up at 6 weeks and 3 months after the therapy. The stability of the joint was evaluated by the index of knee joint stability (IKJS), which was extracted by a novel knee-aiming task combined with the multiscale entropy (MSE) analysis of the complexity of the light spot trajectories. The secondary outcomes were pain on the visual analogue scale (VAS, 0-100), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), quality of life on the Euro-quality of life-5 Dimensional (EQ-5D) VAS form, 30-second chair stand test and 40-meter walk test. One-way repeated measures ANOVA analysis was applied to compare the outcomes at baseline and 6 weeks and 3 months. Pearson partial analysis was used to investigate the correlation between the IKJS and the Kellgren-Lawrence (K/L) rate, pain and knee function. Results: Ninety-six participants ((65±8) years, 21 males, 75 females) completed 3-month follow-up. There was a significant improvement in IKJS at the 6-week visit compared with that at baseline (0.369, 95% confidence interval (CI) 0.241-0.496, P<0.001). The IKJS dropped at 3-month visit compared with 6-week visit, but was still better than that at baseline (0.178, 95%CI: 0.042-0.314, P=0.008). The correlation between IKJS and K/L rate, severity of pain, WOMAC or knee function was not significant (r=-0.131, -0.059, -0.231, 0.124, all P>0.05). There was improvement in pain VAS, WOMAC, EQ-5D-VAS, 30-second chair stand test and 40-meter walk test at 6 weeks and 3 months (all P<0.05). Conclusion: The neuromuscular exercise therapy is effective in improving the joint stability of the knee OA patients. However, the effect gradually diminished over time. In addition, neuromuscular exercise can help relieve pain, improve the function and quality of life in patients with knee OA.

Abstract
OBJECTIVES In a previous real-world study, rivaroxaban reduced the risk of stroke overall and severe stroke compared with warfarin in patients with nonvalvular atrial fibrillation (NVAF). The aim of this study was to assess the reproducibility in a different database of our previously observed results (Alberts M, et al. Stroke. 2020;51:549-555) on the risk of severe stroke among NVAF patients in a different population treated with rivaroxaban or warfarin. MATERIAL AND METHODS This retrospective cohort study included patients from the IBM® MarketScan® Commercial and Medicare databases (2011-2019) who initiated rivaroxaban or warfarin after a diagnosis of NVAF, had ≥6 months of continuous health plan enrollment, had a CHA2DS2-VASc score ≥2, and had no history of stroke or anticoagulant use. Patient data were assessed until the earliest occurrence of a primary inpatient diagnosis of stroke, death, end of health plan enrollment, or end of study. Stroke severity was defined by National Institutes of Health Stroke Scale (NIHSS) score, imputed by random forest model. Cox proportional hazard regression was used to compare risk of stroke between cohorts, balanced by inverse probability of treatment weighting. RESULTS The mean observation period from index date to either stroke, or end of eligibility or end of data was 28 months. Data from 13,599 rivaroxaban and 39,861 warfarin patients were included. Stroke occurred in 272 rivaroxaban-treated patients (0.97/100 person-years [PY]) and 1,303 warfarin-treated patients (1.32/100 PY). Rivaroxaban patients had lower risk for stroke overall (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.76-0.88) and for minor (NIHSS 1 to <5; HR, 0.83; 95% CI, 0.74-0.93), moderate (NIHSS 5 to <16; HR, 0.88; 95% CI, 0.78-0.99), and severe stroke (NIHSS 16 to 42; HR, 0.44; 95% CI, 0.22-0.91). CONCLUSIONS The results of this study in a larger population of NVAF patients align with previous real-world findings and the ROCKET-AF trial by showing improved stroke prevention with rivaroxaban versus warfarin across all stroke severities.

Abstract
OBJECTIVE To describe chronic lymphocytic leukemia (CLL) treatment patterns and patient outcomes in Latin America. METHODS This chart review study (NCT02559583; 2008-2015)evaluated time to progression (TTP) and overall survival (OS) outcomes among patients with CLL who initiate done (n = 261) to two (n = 96) lines of therapy (LOT) since diagnosis. Differences in TTP and OS were assessed by Kaplan-Meier analysis, with a log-rank test for statistical significance. Association between therapeutic regimen and risk for disease progression or death was estimated using Cox proportional hazard regression. RESULTS The most commonly prescribed therapies in both LOTs were chlorambucil-, followed by fludarabine- and cyclophosphamide (C)/CHOP-based therapies. Chlorambucil- and C/CHOP-based therapies were largely prescribed to elderly patients (≥65 years) while fludarabine-based therapy was predominantly used by younger patients (≤65 years). In LOT1, relative to chlorambucil-administered patients, those prescribed fludarabine-based therapies had lower risk of disease progression (hazard ratio [HR] and 95% confidence interval [CI] 0.32 [0.19-0.54]), whereas C/CHOP-prescribed patients had higher risk (HR 95%CI 1.88 [1.17-3.04]). Similar results were observed in LOT2. There was no difference in OS between treatments in both LOTs. DISCUSSION Novel therapies such as kinase inhibitors were rarely prescribed in LOT1 or LOT2in Latin America. The greater TTP observed forfludarabine-based therapies could be attributed to the fact that fludarabine-based therapies are predominantly administered to young and healthy patients. CONCLUSION Chlorambucil-based therapy, which has limited benefits, is frequently prescribed in Latin America. Prescribing novel agents for fludarabine-based therapy-ineligible patients with CLL is the need of the hour. Trial registration: ClinicalTrials.gov identifier: NCT02559583.

Abstract
AIMS Rivaroxaban reduces stroke compared with warfarin in patients with non-valvular atrial fibrillation (NVAF). This study compared healthcare costs before and after stroke in NVAF patients treated with rivaroxaban or warfarin. MATERIALS AND METHODS Using de-identified IBM MarketScan Commercial and Medicare databases, this retrospective cohort study (from 2011 to 2019) included patients with NVAF who initiated rivaroxaban or warfarin within 30 days after initial NVAF diagnosis. Patients who developed stroke were identified, and stroke severity was determined by the National Institutes of Health Stroke Scale (NIHSS) score, imputed by a random forest method. Total all-cause per-patient per-year (PPPY) costs of care were determined for patients: (1) who developed stroke during the pre- and post-stroke periods and (2) who remained stroke-free during the follow-up period. Treatment groups were balanced using inverse probability of treatment weighting. RESULTS A total of 13,599 patients initiated rivaroxaban and 39,861 initiated warfarin, of which 272 (2.0%) and 1,303 (3.3%), respectively, developed stroke during a mean follow-up of 28 months. Among patients who developed stroke, PPPY costs increased from the pre-stroke to post-stroke period, with greater increases in the warfarin cohort relative to the rivaroxaban cohort. Overall, the costs increased by 1.78-fold for rivaroxaban vs 3.07-fold for warfarin; for less severe strokes (NIHSS < 5), costs increased 0.88-fold and 1.05-fold, respectively. Cost increases for more severe strokes (NIHSS ≥ 5) among rivaroxaban patients were half those for warfarin patients (3.19-fold vs 6.37-fold, respectively). Among patients without stroke, costs were similar during the follow-up period between the two treatment groups. CONCLUSIONS Total all-cause costs of care increased in the post-stroke period, and particularly in the patients treated with warfarin relative to those treated with rivaroxaban. The lower rate of stroke in the rivaroxaban cohort suggests that greater pre- to post-stroke cost increases result from more strokes occurring in the warfarin cohort.

Abstract
Objective: To investigate and analyze disease status and risk factors of venous thromboembolism (VTE) during pregnancy and puerperium in our country. Methods: Clinical datas were collected from 575 patients diagnosed with VTE during pregnancy and puerperium and hospitalized in nine medical institutions in our country from January 1, 2015 to November 30, 2019, and retrospectively analyzed it's disease status and risk factors. Results: (1) The proportion of VTE in pregnancy and puerperium was 50.6% (291/575) and 49.4% (284/575), respectively. Four patients died, the mortality rate was 0.7% (4/575). The cause of death was pulmonary embolism. (2) The location of VTE during pregnancy and puerperium was mainly in the lower limb vascular (76.2%, 438/575), followed by pulmonary vessels (7.1%, 41/575). (3) In the risk factors of VTE, cesarean section accounted for 32.3% (186/575), maternal advance age accounted for 27.7% (159/575), braking or hospitalization during pregnancy accounted for 13.6% (78/575), other risk factors accounted for more than 5% were previous VTE, obesity, preterm birth, assistant reproductive technology conception and so on, pre-eclampsia and multiple pregnancy accounted for 4.9% (28/575) respectively. In addition, some patients with VTE did not have any of the above risk factors, and the incidence rate was as high as 23.1% (133/575). Conclusions: The occurrence of VTE during pregnancy and puerperium is related to multiple risk factors, and could lead to matemal death, It is very necessary to screen VTE risk factors for all pregnant women, to make corresponding prevention and control measures.

Abstract
Background and Purpose- Although exogenous hormone therapy (HT) use has been associated with increased risk of ischemic stroke in postmenopausal women, it remains unknown whether sex hormone levels contribute to ischemic stroke risk. We aimed to estimate associations between plasma sex hormone levels and ischemic stroke risk, by HT status, in a nested case-control study of postmenopausal women from the NHS (Nurses' Health Study). Methods- Women with confirmed incident ischemic stroke (n=419) were matched with controls (n=419) by age, HT use, and other factors. Plasma estradiol and testosterone levels were measured using liquid chromatography tandem mass spectrometry; SHBG (sex hormone-binding globulin) was assayed by electrochemiluminescence immunoassay. Associations of total and free estradiol and testosterone, the estradiol/testosterone ratio, and SHBG with ischemic stroke were estimated using conditional logistic regressions stratified by HT status with adjustment for matching and cardiovascular risk factors. Results- Current HT users had different hormone profiles from never/past users. No clear linear trends were observed between estradiol (total or free) levels or the estradiol/testosterone ratio and ischemic stroke risk among either current users (Ptrend>0.1) or never/past users (Ptrend>0.6). For both current and never/past users, the associations between some of the sex hormones and ischemic stroke differed by body mass index categories (Pinteraction≤0.04). For women with a body mass index <25 kg/m2, a higher estradiol/testosterone ratio was associated with significantly elevated ischemic stroke risk among current users (Ptrend=0.01), and higher levels of total and free estradiol were significantly associated with higher ischemic stroke risk among never/past users (Ptrend≤0.04). Testosterone and SHBG were not associated with ischemic stroke in either current or never/past users. Conclusions- Our findings do not support a role of sex hormone levels in mediating ischemic stroke risk among postmenopausal women. Replications in additional larger studies are required.

Abstract
Introduction:
Healthcare expenditures remain unclear in NVAF patients initiating anticoagulation therapy.
Objective:
To compare total healthcare cost in pre- and post-stroke periods between rivaroxaban- and warfarin-treated NVAF patients.
Methods:
This retrospective study using de-identified IBM MarketScan Commercial and Medicare databases (2011-2019) included patients initiating rivaroxaban or warfarin within 30 days after a 1
st
observed NVAF diagnosis who later developed ischemic or hemorrhage stroke. Patients had ≥6 months continuous health plan enrollment, CHA

-VASc score ≥2 and no history of stroke or anticoagulation therapy. Inpatient stroke diagnosis was identified by ICD-9/-10 code, and stroke severity status was defined by National Institutes of Health Stroke Scale (NIHSS) score, imputed by a random forest method. Total per-patient per-year (PPPY) cost of care was calculated pre- and post-stroke (from treatment initiation to time of stroke and from stroke until end of study enrollment, respectively). Cost increases pre-/post-stroke were compared within each treatment cohort.
Results:
During a mean follow up of 25 and 30 months for rivaroxaban and warfarin respectively, 272 (2.0%) and 1,303 (3.3%) patients, respectively, developed stroke. For the rivaroxaban cohort, the pre-/post-stroke cost increase was lower than that for warfarin (1.79-fold vs 3.08-fold, respectively); for more severe stroke (NIHSS ≥6), the cost increase for rivaroxaban was half that of warfarin (3.19-fold increase vs 6.37-fold increase, respectively).
Conclusions:
The study showed a substantial increase in total cost of care following stroke, especially among patients with severe strokes. Warfarin patients had a much higher increase in post-stroke costs relative to rivaroxaban patients, suggesting a benefit of rivaroxaban in preventing strokes with poor outcomes that are costly.

Abstract
Introduction:
The National Institutes of Health Stroke Scale (NIHSS) scores are often not readily available in structured claims databases. We have previously demonstrated that a machine learning model can be used to determine proxies for NIHSS scores. Our current work focuses on creating a model applicable across different databases to validate our approach and enable further outcome studies.
Methods:
We identified 1,415 eligible hospital-admitted patients in the Optum® de-identified Integrated Claims-EMR database who were diagnosed with ischemic or hemorrhagic stroke, or a transient ischemic attack and had NIHSS scores in medical notes. These patients were split into a training (N=1,192) set for model development and a hold-out test (N=223) set to evaluate model performance. Furthermore, model performance was externally validated using the 286 eligible stroke patients in IBM’s Claims-EMR database (CED). Potential predictors for stroke severity included relevant procedures, diagnoses, patient demographics, and information about the patient hospital stay.
Results:
The optimal model, a random forest model, achieved a coefficient of determination (R
2
) between the actual and predicted NIHSS scores in the hold-out Optum dataset of 0.48 and of 0.42 in the secondary CED dataset. The final model incorporated a total of 47 predictors. The strongest predictors included transient ischemic attack diagnosis, length of hospital stay, critical care procedures, patient age, and hemiplegia diagnosis.
Conclusion:
This study shows that machine learning can be used to determine proxies for NIHSS scores across different real-world databases. Ultimately, this will enable large claims-based outcome studies involving stroke severity to improve our understanding of how stroke severity affects healthcare utilization, total cost of care, and the financial impact on the larger community.

Abstract
Although previous studies have suggested a potential role of sex hormones in the etiology of colorectal cancer (CRC), no study has yet examined the associations between circulating sex hormones and survival among CRC patients. We prospectively assessed the associations of prediagnostic plasma concentrations of estrone, estradiol, free estradiol, testosterone, free testosterone and sex hormone-binding globulin (SHBG) with CRC-specific and overall mortality among 609 CRC patients (370 men and 239 postmenopausal women not taking hormone therapy at blood collection) from four U.S. cohorts. Multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazard regression. We identified 174 deaths (83 CRC-specific deaths) in men and 106 deaths (70 CRC-specific deaths) in women. In men, higher circulating level of free testosterone was associated with lower risk of overall (the highest vs. lowest tertiles, HR = 0.66, 95% CI, 0.45-0.99, ptrend = 0.04) and possibly CRC-specific mortality (HR = 0.73, 95% CI, 0.41-1.29, ptrend = 0.27). We generally observed nonsignificant inverse associations for other sex steroids, and a positive association for SHBG with CRC-specific mortality among male patients. In women, however, we found a suggestive positive association of estrone with overall (HR = 1.54, 95% CI, 0.92-2.60, ptrend = 0.11) and CRC-specific mortality (HR = 1.96, 95% CI, 1.01-3.84, ptrend = 0.06). Total estradiol, free estradiol and free testosterone were generally suggestively associated with higher risk of mortality among female patients, although not statistically significant. These findings implicated a potential role of endogenous sex hormones in CRC prognosis, which warrant further investigation.

Abstract
Background Stroke severity is an important predictor of patient outcomes and is commonly measured with the National Institutes of Health Stroke Scale (NIHSS) scores. Because these scores are often recorded as free text in physician reports, structured real-world evidence databases seldom include the severity. The aim of this study was to use machine learning models to impute NIHSS scores for all patients with newly diagnosed stroke from multi-institution electronic health record (EHR) data. Methods NIHSS scores available in the Optum© de-identified Integrated Claims-Clinical dataset were extracted from physician notes by applying natural language processing (NLP) methods. The cohort analyzed in the study consists of the 7149 patients with an inpatient or emergency room diagnosis of ischemic stroke, hemorrhagic stroke, or transient ischemic attack and a corresponding NLP-extracted NIHSS score. A subset of these patients (n = 1033, 14%) were held out for independent validation of model performance and the remaining patients (n = 6116, 86%) were used for training the model. Several machine learning models were evaluated, and parameters optimized using cross-validation on the training set. The model with optimal performance, a random forest model, was ultimately evaluated on the holdout set. Results Leveraging machine learning we identified the main factors in electronic health record data for assessing stroke severity, including death within the same month as stroke occurrence, length of hospital stay following stroke occurrence, aphagia/dysphagia diagnosis, hemiplegia diagnosis, and whether a patient was discharged to home or self-care. Comparing the imputed NIHSS scores to the NLP-extracted NIHSS scores on the holdout data set yielded an R2 (coefficient of determination) of 0.57, an R (Pearson correlation coefficient) of 0.76, and a root-mean-squared error of 4.5. Conclusions Machine learning models built on EHR data can be used to determine proxies for stroke severity. This enables severity to be incorporated in studies of stroke patient outcomes using administrative and EHR databases.

Abstract
Objective: To analyze risk factors, cardiovascular complications, time of death, gestational age of delivery and offspring outcomes in the maternal deaths with cardiovascular diseases (CVD). Methods: Totally 4 112 cases of pregnant women with CVD in Shanghai obstetric heart disease intensive care unit within 26 years (from January 1993 to December 2018) were collected, and 20 maternal deaths within these cases were analyzed retrospectively. Results: (1) Among the 20 deaths, structural heart diseases accounted for 90% (18/20), pregnancy induced heart diseases was 10% (2/20) while there was no dysfunctional heart disease. The mortality of pregnant women with CVD was 0.486% (20/4 112). (2) The following risk factors were common in these women, getting pregnant without counselling (95%, 19/20) , New York Heart Association classⅢ or Ⅳcardiac function (70%, 14/20), complicated with pulmonary hypertension (75%, 15/20) and prior heart events (60%, 12/20). And 85% (17/20) deaths occurred in puerperium, 15% (3/20) occurred before labor,while no death occurred during labor. And 65% (13/20) deaths died due to heart failure, 20% (4/20) deaths were due to pulmonary hypertension crisis, 5% (1/20) died on sudden cardiac arrest, rupture of aortic dissection and sudden death, respectively. Conclusions: Women with CVD should get pregnant after strict evaluation. Pulmonary hypertension is one of the most severe contraindications to pregnancy, especially in patients with moderate to severe pulmonary hypertension. The puerperium period is a critical period that threatens the safety of these patients. Since heart failure is the most common cause of death, it is necessary to prevent and treat heart failure and to monitor heart function dynamically, especially in those with structural abnormal heart diseases. Moreover, it is also of importance to standardize antenatal care and to identify the severity of heart diseases in time.

Abstract
Background and Purpose- Oral anticoagulation therapy is standard of care for patients with nonvalvular atrial fibrillation to prevent stroke. This study compared rivaroxaban and warfarin for stroke and all-cause mortality risk reduction in a real-world setting. Methods- This retrospective cohort study (2011-2017) included de-identified patients from the Optum Clinformatics Database who started treatment with rivaroxaban or warfarin within 30 days following initial diagnosis of nonvalvular atrial fibrillation. Before nonvalvular atrial fibrillation diagnosis, patients had 6 months of continuous health plan enrollment and CHA2DS2-VASc score ≥2. Stroke severity was determined by the National Institutes of Health Stroke Scale, imputed based on machine learning algorithms. Stroke and all-cause mortality risks were compared by treatment using Cox proportional hazard regression, with inverse probability of treatment weighting to balance cohorts for baseline risk factors. Stratified analysis by treatment duration was also performed. Results- During a mean follow-up of 27 months, 175 (1.33/100 patient-years [PY]) rivaroxaban-treated and 536 (1.66/100 PY) warfarin-treated patients developed stroke. The inverse probability of treatment weighting model showed that rivaroxaban reduced stroke risk by 19% (hazard ratio [HR], 0.81 [95% CI, 0.73-0.91]). Analysis by stroke severity revealed risk reductions by rivaroxaban of 48% for severe stroke (National Institutes of Health Stroke Scale score, 16-42; HR, 0.52 [95% CI, 0.33-0.82]) and 19% for minor stroke (National Institutes of Health Stroke Scale score, 1 to <5; HR, 0.81 [95% CI, 0.68-0.96]), but no difference for moderate stroke (National Institutes of Health Stroke Scale score, 5 to <16; HR, 0.93 [95% CI, 0.78-1.10]). A total of 41 (0.31/100 PY) rivaroxaban-treated and 147 (0.44/100 PY) warfarin-treated patients died poststroke, 12 (0.09/100 PY) and 67 (0.20/100 PY) of whom died within 30 days, representing mortality risk reductions by rivaroxaban of 24% (HR, 0.76 [95% CI, 0.61-0.95]) poststroke and 59% (HR, 0.41 [95% CI, 0.28-0.60]) within 30 days. Conclusions- After the initial diagnosis of atrial fibrillation, patients treated with rivaroxaban versus warfarin had significant risk reduction for stroke, especially severe stroke, and all-cause mortality after a stroke. Findings from this observational study may help inform anticoagulant choice for stroke prevention in patients with nonvalvular atrial fibrillation.

Abstract
Transition metal oxides show great potential as electrocatalysts, owing to the low cost and rich chemical states. However, the limited surface areas, low intrinsic activity and poor hydrogen evolution reaction (HER) activity greatly restrict the application for overall water splitting. Herein, we have constructed S doped NiCo2O4 nanosheet arrays by Ar plasma (Ar-NiCo2O4|S) to enhance active sites and boost catalytic kinetics. Consequently, the Ar-NiCo2O4|S shows the improved performances for HER and oxygen evolution reaction (OER). Further, as bifunctional electrocatalysts, Ar-NiCo2O4|S exhibit a voltage of 1.63 V at 10 mA cm-2, as well as good stability.

Abstract
Abstract
Noncoding RNAs account for 80% of human transcripts, but functional studies on noncoding RNAs are relatively few and limited. Long noncoding RNAs (lncRNAs) are known to have an important role in cardiac development, and lately, high-throughput RNA sequencing has been extensively utilized to profile and explore the transcriptome landscape of lncRNAs in failing hearts. These studies have revealed that lncRNAs are mostly dysregulated in failing hearts and their expression signature can discriminate failing hearts of different etiologies.
H19 is abundantly expressed in failing human hearts and its polymorphism was shown to possess a significant correlation with the risk of coronary artery diseases. In our study using murine hearts, we discovered that H19 was significantly up regulated in the heart after ischemic injury, with predominant expression in cardiac fibroblasts. This finding piqued our interest to further investigate the function of H19 in the heart.
We demonstrated that ectopic overexpression of H19 using the AAV approach led to severe cardiac fibrosis in mouse hearts following myocardial infarction. In light of this finding, we generated H19 knockout mice to further investigate the functionality of H19 and we found that cardiac fibrosis was attenuated in these mice. Altogether, these findings suggested that H19 is a fibrosis regulator during cardiac remodeling process after infarction. Due to the multiple regulatory roles of lncRNAs, we then took advantage of chromatin isolation by RNA purification (ChIRP) to identify the H19-interacting protein, YB-1. Surprisingly, mice with YB-1 knockdown displayed severe cardiac fibrosis even without injury. Furthermore, we demonstrated that YB-1 is a transcriptional suppressor of collagen 1A1. Knockout of H19 in YB-1 knockdown partially suppressed Col1a1 expression, which suggests a negative regulatory role of H19 on YB-1 towards the expression of Col1a1.
Taking into account all of these findings, we concluded that H19 mediates collagen expression in fibroblasts through the inhibition of YB-1 activity during cardiac remodeling.

Abstract
Objective: To investigate the microbiological test, antibiotic sensitivity and surgical treatment of periprosthetic joint infection(PJI) cases in post total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients. Methods: A retrospective cross-sectional survey was conducted on 318 patients who underwent THA or TKA in 9 clinical centers in Beijing from January 2014 to December 2016.The data of microbiology, antibiotic sensitivity and surgical treatment were collected.The average age of patients was (62.3±13.1) years old (range: 21-86 years old), including 145 males and 173 females.The body mass index was (25.6±3.8) kg/m (2) (range: 15.6-38.1 kg/m(2)). Results: In total, 318 patients had microorganisms detected by periprosthetic tissue culture or synovial fluid culture, 209 cases (65.7%) had Gram-positive bacteria, 29 cases (9.1%) had Gram-negative bacteria, 10 cases (3.1%) had fungi, 3 cases (0.9%) had non-tuberculous mycobacteria, 72 cases (22.6%) were negative, 69 cases (21.7%) had methicillin-resistant bacteria. The antibiotic sensitivity results showed that the overall resistance rate of penicillin, cefuroxime, amoxicillin+clavulanic acid was 79.9%, 69.9%, and 68.1%, respectively; meropenem, vancomycin, and linezolid resistance rate was 0. For the treatment methods of hip and knee PJI, two-stage revision surgery acounted for 72.9% (108/148) and 64.1% (109/170), respectively. One-stage revision surgery accounted for 21.6% (32/148) and 7.6% (13/170), and open debridement surgery accounted for 4.7%(7/148) and 26.4% (45/170). Conclusions: Gram-positive bacteria was still the main pathogen of PJI.The methicillin-resistant bacteria and rare bacteria should be payed attention to. The Majority of hip and knee PJI cases were treated by two-stage revision surgery.

Abstract
Limited data are available regarding contemporary multiple myeloma (MM) treatment practices in Latin America. In this retrospective cohort study, medical records were reviewed for a multinational cohort of 1103 Latin American MM patients (median age, 61 years) diagnosed in 2008–2015 who initiated first‐line therapy (LOT1). Of these patients, 33·9% underwent autologous stem cell transplantation (ASCT). During follow‐up, 501 (45·4%) and 129 (11·7%) patients initiated second‐ (LOT2) and third‐line therapy (LOT3), respectively. In the LOT1 setting, from 2008 to 2015, there was a decrease in the use of thalidomide‐based therapy, from 66·7% to 42·6%, and chemotherapy from, 20·2% to 5·9%, whereas use of bortezomib‐based therapy or bortezomib + thalidomide increased from 10·7% to 45·5%. Bortezomib‐based therapy and bortezomib + thalidomide were more commonly used in ASCT patients and in private clinics. In non‐ASCT and ASCT patients, median progression‐free survival (PFS) was 15·0 and 31·1 months following LOT1 and 10·9 and 9·5 months following LOT2, respectively. PFS was generally longer in patients treated with bortezomib‐based or thalidomide‐based therapy versus chemotherapy. These data shed light on recent trends in the management of MM in Latin America. Slower uptake of newer therapies in public clinics and poor PFS among patients with relapsed MM point to areas of unmet therapeutic need in Latin America.

Abstract
Objective:
To compare total cost of care in pre- and post-stroke periods between rivaroxaban- and warfarin-treated NVAF patients.
Methods:
De-identified Optum Clinformatics® Database (OptumInsight, 2011-17) was used in this study of patients initiating rivaroxaban or warfarin within 30 days after a 1
st
observed NVAF diagnosis. Patients had ≥6 months continuous health plan enrollment, CHA2DS2-VASc score ≥2 and no history of stroke or anticoagulation. Inpatient stroke diagnosis was identified by ICD-9/-10 code, and severity status was defined by National Institutes of Health Stroke Scale (NIHSS) score, imputed by a random forest method. For all patients who developed stroke, total per-patient per-month (PPPM) cost of care was estimated before (from treatment initiation to time of stroke) and after (from stroke until the earliest of either death or end of enrollment) stroke occurrence. Generalized linear models adjusted for confounders were used to compare PPPM cost between the 2 groups in the 2 periods, with gamma distribution, log link and weighted by follow up.
Results:
During a mean follow up of 27 months, 2.6% of rivaroxaban and 3.9% of warfarin patients developed stroke and were included in the analysis. During pre-stroke period, total cost of care was similar for both treatment groups (~$3400 PPPM), which increased 3-fold in the post-stroke period (Table 1). During post stroke period, total cost of care was 21% lower for rivaroxaban patients vs. warfarin. Of those with less severe stroke (NIHSS<16) total cost was 40% lower for rivaroxaban patients vs. warfarin.
Conclusions:
Total cost of care for stroke prevention was similar in rivaroxaban and warfarin treated patients, but post-stroke cost was lower in rivaroxaban patients. These findings suggest favorable long-term cost benefit with rivaroxaban, driven by significant savings in less severe stroke.

Abstract
At present, several clinical practice guidelines for osteoarthritis have been developed. Although contradictions about some recommendations are still in dispute, large number of clinical practice guidelines recommended core treatments, namely education, weight loss and exercise therapy. Thus, the diagnosis and treatment of primary osteoarthritis should focus on the above three treatments. However, we have to develop the clinical practice guidelines for osteoarthritis in primary hospital, based on the characteristics of osteoarthritis in China, the burden of disease, the health literacy of patients and the clinical decision-making of diagnosis and treatment of primary osteoarthritis in primary medical care.We suggest to formulate guidelines for the diagnosis and treatment of osteoarthritis in primary medical care to regulate primary interventions.

Abstract
89 Background: Although patients with CRPC frequently develop metastasis within 3 years following castration resistance, the impact of metastasis on HRU in these patients is not well understood. Methods: The Optum de-identified electronic health record database (1/1/2007 – 4/30/2016) was used in this single cohort observational study comparing HRU after metastasis with HRU before metastasis. The cohort included only non-metastatic CRPC (nmCRPC) patients who later developed metastasis. The pre-metastasis period spanned from nmCRPC identification to development of metastasis; the post-metastasis period spanned from metastasis until death or end of data availability. Per-patient per-month (PPPM) HRU was estimated during both pre- and post-metastasis periods by a generalized linear mixed model adjusted for log-transformed baseline PSA, age, testosterone levels, and Charlson Comorbidity Index. Results: With a mean time of 11 and 17 months of pre- and post-metastasis periods, respectively, 540 CRPC men were included, with a mean age at nmCRPC identification of 75 years. Higher HRU was seen across all service types during the post-metastasis period. There was a 2.5-fold increase in inpatient admissions and a 6.4-fold increase in inpatient length-of-stay in the post-metastasis period compared to the pre-metastasis period (p < 0.01). For emergency department (ED) visits, there was a 2.0-fold increase from the pre- to post-metastasis periods (p < 0.01). For observation unit visits, a 2.7-fold increase was seen in the post-metastasis period (p < 0.01). Finally, patients were 40% more likely to have an office visit after developing metastasis (p < 0.01). The PPPM use of intensive care unit, hospice or skilled nursing facility were too low for meaningful comparison between the pre- and post-metastasis periods. Conclusions: Shorter time to metastasis was observed in this cohort vs. other nmCRPC studies, likely due to delayed disease identification. CRPC patients incurred substantially higher HRU after developing metastasis, attributable to inpatient, ED, observation unit as well as office visits, suggesting that delaying metastasis may reduce or delay the increased HRU in patients with nmCRPC.

Abstract
Idiopathic thrombocytopenic purpura (ITP) is an acquired thrombocytopenia without other clear cause of thrombocytopenia. It is not common in a singleton pregnancy and less common in twin pregnancy. We report a 33-year-old ITP pluripara whose first pregnancy was uneventful. She carried twin pregnancy, complicated by recurrent very low platelets, and gave birth to preterm twins. This patient received multiple courses of intravenous immunoglobulin (IVIG) and showed a significant platelet count improvement with IVIG therapy.

Abstract
Objective: To observe and analyze the difference of serum immunoglobulin IgA, IgG, IgM, β2-microglobulin and transferrin in pre-eclampsia (PE) and pregnancies complicated with chronic kidney disease. Methods: Totally 46(40.0%) pregnancies with PE (PE group), 36(31.3%) pregnancies with chronic kidney disease (chronic kidney disease group) and 33(28.7%) normal pregnancies with normal blood pressure and proteinuria without any complication (control group) delivered in Renji Hospital were recruicted in this study from February 2017 to July 2017. Serum IgA, IgG, IgM, β2-microglobulin and transferrin levels were detected. Correlation tests were conducted between these indicators and blood pressure, 24 hours proteinuria value and delivery weeks. Results: (1) Comparison of general situation of pregnancies in the 3 groups: there were no significant difference in the age and child bearing history between the 3 groups (all P>0.05), while there was a significant difference in the blood pressure and deliver week (all P<0.01). There was no significant difference in 24 hours proteinuria values between PE group and chronic kidney disease group (Z=-0.187, P=0.852). (2) Comparison of serum immunoglobulin, β2-microglobulin and transferrin levels in pregnant women with three groups: serum IgA level in chronic kidney disease group was significantly higher than those in PE and control groups [(2.4±0.9) vs (1.8±0.9) vs (1.6±0.6) g/L; F=9.959, P<0.01]. The serum IgG and IgM values had no significant difference between the 3 groups (all P>0.05). Serum β2-microglobulin in chronic kidney disease group was significantly higher than those in PE and control groups [(4.0±2.6) vs (2.7±0.7) vs (2.0±0.5) mg/L; F=15.892, P<0.01]. Serum transferrin in chronic kidney disease group was significantly lower than those in PE and control groups [(3.0±0.8) vs (3.7±1.1) vs (3.6±0.6) g/L; F=6.284, P<0.01]. (3) The correlation between serum immunoglobulin, β2-microglobulin, transferrin and blood pressure, proteinuria value and delivery weeks in PE group: the blood pressure level was not correlated with serum IgA, β2-microglobulin and transferrin values in PE group (all P> 0.05). So, 24 hours proteinuria value was positively correlated with β2-microglobulin (r=0.557, P<0.01), which was negatively correlated with transferrin (r=-0.442, P<0.01) and was not correlated with IgA(r=0.089, P=0.556). There was a negative correlation between delivery weeks and β2-microglobulin (r=-0.328, P=0.026), and positive correlation with transferrin (r=0.315, P=0.035) and no correlation with IgA (r=-0.169, P=0.260). (4) The correlation between serum immunoglobulin, β2-microglobulin, transferrin and blood pressure, proteinuria value and delivery weeks in chronic kidney disease group: the blood pressure level was positively correlated with β2- microglobulin (systolic pressure: r=0.598, P<0.01; diastolic pressure:r=0.557, P<0.01), which was not correlated with IgA and transferrin in chronic kidney disease group (all P>0.05). So, 24 hours proteinuria value was positively correlated with β2-microglobulin and IgA (r=0.568, r=0.330, both P<0.05), and not correlated with transferrin (r=0.255, P=0.133). Delivery weeks had a negative correlation with β2-microglobulin (r=-0.574, P<0.01), while it had a positive correlation with transferrin (r=0.369, P=0.027). No correlation was found between delivery weeks and IgA values (r=-0.257, P=0.131). Conclusion: The serum levels of IgA, β2-microglobulin and transferrin in PE and pregnancies with chronic kidney disease are significantly different, which may provide clinical value for the diagnosis of PE and pregnancies with chronic kidney disease in future.

Abstract
27 Background: Currently there is insufficient guidance for the management of nmCRPC. This study assessed patient risk of developing metastases and death based on their PSA levels over time. Methods: This was a retrospective study using the Optum electronic health record database (1/1/2007 – 4/30/2016) in men ≥18 years. nmCRPC was defined as a PC diagnosis, 2 rising PSA levels ≥1 week apart, testosterone < 50 ng/dL (post-PC diagnosis), and no ICD-9/10 code or therapy indicating metastasis. Patients were required to have ≥1 PSA record per 3-month period for 9 months following nmCRPC diagnosis. Group Based Trajectory Modeling (GBTM) was used to group patients based on similar PSA trends over 9 months. The association of these PSA groups with metastasis/mortality risk was measured using multivariate Cox proportional hazard regression models. An overall trend for metastasis and mortality across the groups was also tested. Results: From a total of 729 patients included, 4 distinct groups were identified: Group 1 (49% of patients), 2 (32%), 3 (14%) and 4 (5%). Group 1 had the lowest PSA (7 ng/mL) at nmCRPC diagnosis and steady PSA during the 9-month follow-up. In contrast, Groups 2, 3 and 4 had higher PSA at nmCRPC diagnosis (17, 61, 513 ng/mL respectively) and rising PSA during follow-up. There was a trend of increasing metastasis and mortality risk (p < 0.001 for both trends) with the higher PSA groups. For metastasis, Hazard Ratios (HRs) and 95% confidence intervals (CIs) were 1.7 (1.3-2.2), 3.5 (2.5-5.0), 1.8 (0.7-4.7) in Groups 2, 3 and 4, respectively, vs. Group 1. For mortality, HRs (95% CIs) were 1.9 (1.4-2.5), 2.6 (1.8-3.7), 4.5 (2.4-8.4) in Groups 2, 3 and 4, respectively, vs. Group 1. Metastasis-free survival (MFS) independently predicted mortality risk. Patients developing metastasis within 1 year had 4.4-fold greater risk for mortality (95% CI = 2.2-8.8) than those who remained MFS at year 3. Conclusions: A large proportion of nmCRPC patients with PSA increases during the follow-up period had significantly increased risk for metastasis and mortality, with MFS predicting mortality risk. Periodic measurement of PSA may better inform management of nmCRPC.

Abstract
Background:
While several studies have evaluated healthcare costs of stroke, limited data are available on long-term costs by stroke severity.
Objective:
To assess healthcare costs in relation to stroke severity over 3 years following stroke diagnosis.
Methods:
Patients with newly diagnosed stroke were assessed using OPTUM de-identified Integrated Claims-Medical Record Database (2007-2016). The National Institutes of Health Stroke Scale (NIHSS) score, imputed by 100 clinically relevant predictors selected by a random forest method, was used to group patients by severity: no impairment (<1, NI), minor (1-5, Min), moderate (>5-16, Mod), moderately severe (>16-21, MS), severe (>21-42, S). All-cause medical and pharmacy costs were estimated in patients for up to 3 years following diagnosis. Mean cumulative costs were evaluated by partitioning the follow-up period into 2-week intervals. The average cost incurred in each interval was then weighted by the Kaplan-Meier survival probability at the beginning of each interval, after which costs were summed across all intervals.
Results:
We identified 8512 patients with a mean age of 69 years at first stroke diagnosis; 1396, 4783, 1927, 215 and 191 were in the NI, Min, Mod, MS, and S cohorts, respectively. Mortality was 3%, 13%, 33%, 88% and 100% at Year 3 following stroke diagnosis in the NI, Min, Mod, MS, and S cohorts, respectively. In year 1 following diagnosis, the cumulative total healthcare costs were the highest in the Mod cohort (mean ± SE; $67365±$1234) and lowest in the S cohort ($15945±$647). Healthcare costs increased in year 3 substantially compared to year 1, with the NI cohort showing the greatest increase in healthcare costs (116% increase), followed by the Min (86%), Mod (39%), MS (9%) and S (0%) cohorts. Hospitalization was the costliest healthcare service across all cohorts and ranged in Year 3 from $62100 in the Mod cohort to $13241 in the S cohort; outpatient services were the second most costly.
Conclusion:
Majority of patients with severe strokes (MS and S) incurred high healthcare costs within a month whereas patients with less severe strokes (Min and NI) accrued more costs over time due to better survival outcomes, underscoring short and long-term economic burden of various degrees of stroke severity.

Abstract
Background:
The National Institutes of Health Stroke Scale (NIHSS) score has been used to measure initial stroke severity. However, limited data are available on the utility of NIHSS in predicting all-cause mortality risk.
Objective:
To assess the association between stroke severity and mortality in stroke patients, using NIHSS stroke severity scoring.
Methods:
This retrospective cohort study followed patients after first inpatient diagnosis of stroke using OPTUM de-identified Integrated Claims-Medical Database (2007-2016). The NIHSS score was imputed using 100 clinically relevant predictors selected by a random forest method. Patients were classified by NIHSS score into 5 severity groups: no impairment (<1, NI), minor (1-5, Min), moderate (>5-16, Mod), moderately severe (>16-21, MS) or severe (>21-42, S). Patients were followed from stroke diagnosis to the earliest occurrence of either death, end of data or lost to follow-up. Time to death was assessed by Cox proportional hazard regression, comparing more severe stroke patients vs the NI patients (reference group), adjusting for age, gender, comorbidity index, and region.
Results:
A total of 16,554 stroke patients were studied; 17%, 57%, 22%, 2%, and 2% were in None, Min, Mod, MS and S groups, respectively. Mean age was 68 years at stroke diagnosis (ranging 64 to 79 years). Overall, 4.3% had a history of atrial fibrillation and 3.1% received anticoagulants for stroke prevention. Median follow-up was 23, 18, 10, 0.9 and 0.6 months for the None, Min, Mod, MS and S cohorts, respectively. Following stroke diagnosis, 74% of MS and 89% S patients died within 30 days of stroke onset, whereas the NI and Min patients remained alive within 30 days. When compared with the NI patients, more severe patients had significantly increased mortality risk; hazard ratios (95% confidence intervals) were 2.8 (2.2-3.6), 9.7 (7.4-12.6), 116 (86-154), and 364 (270-491) for the Min, Mod, MS and S patients, respectively.
Conclusions:
Mortality rates increased significantly with more severe strokes, as determined by the initial NIHSS score. Over 75% of the patients with moderately severe and severe strokes died within 1 month following stroke diagnosis.

Abstract
Objective: To explore the influence of different inner dressings in negative-pressure wound therapy (NPWT) on escharectomy wound of full-thickness burn rabbits. Methods: Eighteen Japanese white rabbits were inflicted with full-thickness burn on unilateral back. They were divided into polymer dressing group (PD), biological dressing group (BD), and silver biological dressing group (SBD), according to the random number table, with 6 rabbits in each group. On 3 days post burn, the wounds were performed with escharectomy, and then wounds of rabbits in group PD were covered with polyurethane foam. Wounds of rabbits in group BD were covered with porcine acellular dermal matrix (ADM) and wounds of rabbits in group SBD were covered with silver porcine ADM. Then continuous NPWT was performed on rabbits of the three groups for 7 days. Immediately after surgery and on post surgery day (PSD) 7, general observation of wound was conducted and tissue around the wound was harvested for determination of dry to wet weight ratio. The content of bacteria was counted and the content of tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and IL-6 in wound was determined by enzyme-linked immunosorbent assay. Fibroblasts in wound were counted after Masson staining and number of microvessels was counted after CD31 antibody immunohistochemical staining. Data were processed with analysis of variance for repeated measurement, LSD-t test, paired samples t test, and Bonferroni correction. Results: (1) Immediately after surgery, there was no granulation tissue in basal wound of rabbits in the three groups, with rich blood supply and obvious edema. On PSD 7, much granulation tissue was found in basal wound of rabbits in the three groups, with no or mild edema and no obvious redness and swelling in wound edge. (2) There were no significant differences in dry to wet weight ratios of tissue around the wound among and within the three groups immediately after surgery and on PSD 7 (with F values respectively 0.70 and 0.09, t values from 0.17 to 0.52, P values above 0.05). (3) Immediately after surgery, the content of bacteria in wounds of rabbits in groups PD, BD, and SBD was respectively (603.0±146.0) ×10(4,) (573.0±63.0) ×10(4,) and (590.0±100.0)×10(4) colony-forming unit (CFU)/g, with no significant difference among them (F=0.13, P>0.05). On PSD 7, the content of bacteria in wounds of rabbits in groups PD, BD, and SBD were respectively (5.4±0.8) ×10(4,) (4.6±0.9) ×10(4,) and (3.5±0.9)×10(4) CFU/g. Among them, the content of bacteria in wounds of rabbits in group SBD was lower than that in groups PD and BD, respectively (with t values respectively 3.78 and 2.29, P<0.05 or P<0.01). The content of bacteria in wounds of rabbits in the three groups on PSD 7 was decreased compared with that immediately after surgery (with t values from 10.05 to 21.81, P values below 0.01). (4) There was no significant difference in content of TNF-α, IL-1β, and IL-6 in wounds of rabbits in the three groups immediately after surgery and on PSD 7 (with F values from 0.10 to 1.89, P values above 0.05). The content of TNF-α in wounds of rabbits in the three groups on PSD 7 was significantly higher than that immediately after surgery (with t values from 2.93 to 5.01, P<0.05 or P<0.01). (5) There was no significant difference in amount of fibroblasts in wounds of rabbits in the three groups immediately after surgery and on PSD 7 (with F values respectively 0.01 and 0.81, P values above 0.05). The amount of fibroblasts in wounds of rabbits in the three groups on PSD 7 was larger than that immediately after surgery (with t values from 4.78 to 11.58, P values below 0.01). (6) There was no significant difference in number of microvessels in wounds of rabbits in the three groups immediately after surgery and on PSD 7 (with F values respectively 2.42 and 2.49, P values above 0.05). The number of microvessels in wounds of rabbits in the three groups on PSD 7 was larger than that immediately after surgery (with t values from 7.17 to 11.14, P values below 0.01). Conclusions: SBD is better at inhibiting the growth of bacteria. PD, BD, and SBD have almost the same effects on reducing tissue edema and inflammatory reaction, and on promoting the accumulation of collagen fibers and tissue vascularization.

Abstract
BACKGROUND The Women's Health Initiative (WHI) Dietary Modification (DM) trial did not show that reductions in dietary fat accompanied by increases in vegetable and fruit consumption decrease the incidence of colorectal cancer. Secondary analyses suggested that aspirin use may modify the intervention effects of DM on colorectal cancer development, although a recent reanalysis including the postintervention period confirmed no main effect of the intervention on reducing colorectal cancer incidence Methods: We analyzed data from 48,834 postmenopausal women who were randomized into the low-fat DM (N = 19,540) or comparison (N = 29,294) group for an average 8.1 years and followed for an additional 9.4 years through August 31, 2014. Exposure to specific class(es) or strength(s) of nonsteroidal anti-inflammatory drugs (NSAIDs) was modeled at baseline and as time-dependent use through the 9-year clinic visit. A Cox proportional hazard model was employed to assess the association of the DM, medication use, and their interaction with colorectal cancer events. RESULTS A total of 906 incident cases of colorectal cancer were identified during the intervention and postintervention periods. By both exposure models, we found that colorectal cancer incidence was not different in the DM from the comparison group among any type of NSAID users. None of the interactions with any category of NSAID use was statistically significant; however there was most modest evidence for an interaction (p = 0.07) with aspirin use at baseline (hazard ratio [HR] = 0.81, 95% confidence interval [CI], 0.60-1.11 for users; HR = 1.12, 95% CI, 0.97-1.30 for nonusers). Strength and duration of aspirin use at baseline did not alter the associations. CONCLUSION Extended follow-up of women in the WHI DM trial did not confirm combined protective effects of aspirin and low-fat diet on colorectal cancer risk among the postmenopausal women.

Abstract
Objective: To evaluate the efficacy and safety of oseltamivir in the treatment of suspected influenza in children. Method: A multicenter, randomized and open-label trial was conducted among 229 individuals with suspected influenza which were collected from the clinic of 5 hospitals in Guangdong province (Guangzhou Women and Children's Medical Center, Shenzhen Baoan District Maternity and Child Care Service Center, the Second Affiliated Hospital of Shantou University Medical College, Dongguan Maternity and Child Care Service Centre, Yuexiu District Children's Hospital of Guangzhou) from April to July 2015. They were randomized either to oseltamivir group (oseltamivir 30-75 mg, twice daily for 5 days) or control group who were given symptom relief medicines for 5 days. Result: No significant difference was found between two groups in influenza symptoms of the patients before the treatment(P>0.05). Altogether 229 individuals (114 in oseltamivir group, 115 in control group) were analyzed for efficacy, in which 73 individuals (42 oseltamivir, 31 control), 31.9%, were identified as influenza-infected through laboratory test. No significant difference was found between the two groups in the duration of fever although shortened. In the 229 individuals , the cumulative alleviation proportion between oseltamivir and control group was not significantly different (P>0.05): the median duration of illness was 69.9 hours (95% CI 65.3-91.5) in oseltamivir group and 75.4 hours (95%CI 63.9-91. 7) in control group; the median duration of fever was 40.4 hours (95%CI 31.5-53.4) in oseltamivir group and 44.0 hours (95%CI 33.2-50.0) in control group. In the 73 individuals, the cumulative alleviation proportion between oseltamivir and control group was significantly different (P<0.05). The median duration of illness was 61.2 hours (95%CI 48.0-121. 0) in oseltamivir group, being significantly shorter than that of 116.0 hours (95%CI 91.5-175.0) in control group. But it was not significantly different that the median duration of fever was 32.8 hours (95%CI 24.0-47.0 ) in oseltamivir group and 55.8 hours (95%CI 43.6-78.3 ) in control group (P>0.05). And the median duration of fever in 60 individuals (38 oseltamivir, 22 control) was significantly different between two groups(P<0.05), who had finished a course of taking oseltamivir in the 73 individuals, 34.8 hours (95%CI 24.0-48.5 ) in oseltamivir group being significantly shorter than that of 53.3 hours (95%CI 43.6-104.0 ) in control group. There was certain difference in side effects rate between the two groups (oseltamivir 10%, control 2%, P<0.05). The main side-effects were gastrointestinal symptoms (stomachache, diarrhea, poor appetite, vomiting). Conclusion: The duration of illness and fever in suspected influenza patients treated with oseltamivir was shorter than those in the patients treated with no oseltamivir, the difference was not statistically significant, when 31.9% was confirmed with positive result of virus test in suspected influenza in children. But in these patients with positive result of virus test, the duration of illness was significantly shortened with treatment with oseltamivir as compared with no treatment with oseltamivir, and it would be better if full oseltamivir course was completed for reducing the duration of fever. Oseltamivir treatment was safe with mild side effects.

Abstract
At present, several clinical practice guidelines for the treatment of osteoarthritis have been developed by institutes or societies. The ultimate purpose of developing clinical practice guidelines is to formulate the process in the treatment of osteoarthritis effectively. However, the methodologies used in developing clinical practice guidelines may place an influence on the transformation and application of that in treating osteoarthritis. The present study summarized the methodological features of individual clinical practice guideline and presented the tools for quality evaluation of clinical practice guideline. The limitations of current osteoarthritis guidelines of China are also indicated. The review article might help relevant institutions improve the quality in developing guide and clinical transformation.

Abstract
5027 Background: Interventions in nmCRPC are the last defense against metastasis, which drives health care cost and mortality. To assess the value of such interventions we must analyze risk factors for metastasis and death. Methods: This was a retrospective study of data (Optum electronic health record database, 2007 – 2016) from men with a prostate cancer diagnosis, 2 rising PSA levels ≥1 week apart, castrate level ( < 50 ng/dL) testosterone (T) and no ICD-9/10 code or therapy indicating metastasis. Gleason grade (G) and PSA data up to and including nmCRPC index date (ie, date of 2nd PSA rise) were used to assign NCCN risk groups: Low (G ≤6 and PSA < 10 ng/mL), Intermediate (IM) (G = 7 or 10 ≤ PSA ≤ 20 ng/mL) or High (G ≥ 8 or PSA > 20 ng/mL). The LP/NG group comprised men with PSA < 10 ng/mL (LP) and missing G (NG). A Cox proportional hazard model, adjusted for age, race, comorbidity index score, T level, therapy type and bone scans was used to compare LP/NG, IM and High with the Low risk group. Results: Among 1008 men with nmCRPC (mean age 76 years; 12% African American), 553 developed metastases and 430 died during follow-up. Mean time to metastasis was 28, 22, 15, 13 months in the Low, LP/NG, IM, and High groups, respectively. In the Low group, 9 of 29 (31%) men developed metastases, vs 131/285 (46%) in the LP/NG group (hazard ratio [HR] = 1.70, 95% confidence interval [CI]: 0.86-3.35), 175/320 (55%) in the IM group (HR = 2.52, 95% CI: 1.28-4.91) and 238/374 (64%) in the High group (HR = 3.63, 95% CI: 1.85-7.10). Mean time to death was 32, 30, 24, 21 months in the Low, LP/NG, IM, High groups, respectively. There were 8 deaths in the Low group (27.6%), vs 101 (35.4%) (HR = 1.35, 95% CI: 0.65-2.79) in the LP/NG group, 124 (38.8%) (HR = 1.79, 95% CI: 0.87-3.70) in the IM group and 197 (52.7%) (HR = 2.96, 95% CI: 1.45-6.05) in the High group. The High risk group was more likely to develop metastasis during the first year and die within the first 2 years. Conclusions: Metastasis and death occurred earlier and more frequently in the Intermediate and High groups relative to the Low risk group. These findings may further inform diagnostic and management strategies for combating disease progression.
