Abstract
Objective: To explore the risk factors for lateral neck recurrence of central lymph node metastasis (CLMN) in papillary thyroid cancer (PTC), and to construct a model to predict the recurrence. Methods: The records of 245 consecutive PTC patients with CLMN underwent surgical treatment from 1996 to 2009 in our department were retrospectively reviewed. The threshold value of CLNM number is determined by ROC curve. The risk factors for lateral neck recurrence were determined by using Cox regression model. The identified risk factors were incorporated into a nomogram model to predict the risk of lateral neck recurrence. Results: A total of 245 patients were enrolled in the study, among them, 32 cases occurred lateral neck lymph node recurrence and 4 cases were dead of thyroid carcinoma. Multivariate analysis revealed that primary tumor size, extrathyroidal extension, the number of metastatic CLNM >3 were independent risk factors of lateral neck recurrence (P<0.05), lateral neck recurrence was a risk factor of disease-free survival(P<0.05). The nomogram model of predicting the lateral neck recurrence was further established based on the above 3 independent risk factors, the area under the receiver operating characteristic (ROC) curve of which was 0.790. Conclusions: The nomogram model based on the independent risk factors of LN recurrence can be helpful to screen the papillary thyroid carcinoma patients with high risk of lateral neck recurrence, and provide more guidance for clinical treatment.

Abstract
OBJECTIVE To examine the effect of Medicaid managed care (MMC) versus Medicaid fee-for-service (FFS) on emergency department (ED) use and hospitalization during the first 6 and 12 months of life among low-birth-weight (LBW) infants. METHODS We used the New York City Office of Vital Statistics-Statewide Planning and Research Cooperative System (OVS-SPARCS) dataset to identify 9135 LBW infants born to female Medicaid beneficiaries in New York City from January 2008-March 2012. We applied a robust regression discontinuity framework using a New York State Medicaid policy in effect at that time. This policy automatically enrolled infants born to female Medicaid beneficiaries to Medicaid managed care (MMC) or Medicaid fee-for-service (FFS) based on their birth weight (less than 1200 g vs. 1200-2500 g) during the first 6 months of their lives. RESULTS LBW infants in MMC had an average 0.16% points higher probability of being hospitalized within the first year of their lives than those in Medicaid FFS (p-value = 0.04). CONCLUSIONS FOR PRACTICE More research is necessary to understand possible differences in healthcare utilization between MMC and FFS participants with high health risks.

Abstract
Objective: To explore the visual fixation patterns during facial emotion recognition and the association between fixation duration percentage (FDP) of eye region with social impairment among high-functioning autism spectrum disorders (HFASD). Methods: Children were recruited from the Child and Adolescent Behavior Research Center of Sun Yat-sen University, Guangzhou, between July and December 2019 for case control study. A total of 42 children with HFASD and 23 age-and gender-matched typical development (TD) children were enrolled. Based on their performance during the facial emotion recognition task, HFASD children were further divided into ASD-1 group (correctly recognized both happy and fear emotions) and ASD-2 group (recognized happy emotions only). During the free viewing task, an infrared eye tracker was used to record the gazing data of children in the three groups. The social responsiveness scales (SRS) was utilized to evaluate HFASD children's social impairment, with the cutoff score of 75 to differentiate those from mild and severe social impairment. The differences of FDP among the three groups were analyzed by the Analysis of Variance (ANOVA) model. Mixed linear regression model was conducted to evaluate the associations between social impairment and FDP of eye region among HFASD children. Results: The final sample consists of 25 ASD-1 (20 males, aged (7.9±1.0) years), 17 ASD-2(14 males, aged (7.2±1.2) years), and 23 TD (12 males, aged (7.7±1.3) years) children. There were no significant differences in age and gender among three groups (F=2.05, χ²=10.08, P=0.14 and 0.07, respectively). For the happy emotion, there are significant differences in eye FDP among the three groups (TD: 0.37±0.20, ASD-1: 0.35±0.20, ASD-2: 0.47±0.24, F=3.97, P=0.02). Mixed linear regression model revealed that, adjusting for emotion, gender, age and intelligence quotient, ASD children's eye FDP negatively associates with social impairment (OR=0.15, 95%CI: 0.06-0.35, P<0.01). Conclusions: Longer FDP is associated with milder social impairment among HFASD children. HFASD children with facial emotion recognition difficulties require longer fixation to recognize happy emotions.

Abstract
Objective: To predict and investigate the potential risk factors for the upper mediastinal metastasis of papillary thyroid carcinoma (PTC). Methods: This study was a prospective cohort study. The admission criteria were patients with untreated thyroid cancer diagnosed in Cancer Hospital, Chinese Academy of Medical Sciences from December 2013 to December 2015, and positive lymph node (cN1, including cN1a and cN1b) was diagnosed by ultrasound. All patients underwent neck to thorax enhanced Computed Tomography (CT) examination preoperatively. All patients with suspected upper mediastinal lymph node metastasis experienced suspicious regional dissection, and those who had not undergone surgery and whose postoperative pathology was non-papillary thyroid carcinoma were excluded. Kaplan-Meier method was selected for survival analysis and all the factors were analyzed by multivariate Logistic regression. Results: Of the 248 patients, 54 were prompted by postoperative pathology for upper mediastinal lymph node metastasis, 86 cases were phase T1, 94 cases were phase T2, 17 cases were phase T3 and 51 cases were phase T4, 21 cases were N1a phase and 227cases were N1b phase. There was a statistically significant difference in the T-phase and N-phase between the upper mediastinal lymph node metastasis group and no upper mediastinal lymph node metastasis group(P<0.05). Univariate analysis showed that among the preoperative relevant factors, ultrasound tumor length> 2 cm, ultrasound tumor bilaterally, CT double neck lymph node metastasis, increased thyroglobulin (Tg), and increased anti-thyroglobulin antibody (ATG) were all risk factors for upper mediastinal lymph node metastasis(all P<0.05). Among the postoperative factors, bilateral tumor, double neck lymph node metastasis, tumor invasion of the recurrent laryngeal nerve, trachea, esophagus or larynx, T3 staging, T4 staging, total number of metastatic lymph nodes>10, the number of metastatic lymph nodes in level Ⅵ>3 and >6, the proportion of metastatic lymph nodes in level Ⅵ>1/2, the number of metastatic lymph nodes in level Ⅳ> 5 and metastatic proportion >1/3 are risk factors for metastasis of upper mediastinal lymph node(all P<0.05). Multivariate analysis showed that CT indicated double neck lymph node metastasis, increased Tg, increased ATG, the proportion of metastatic lymph nodes in level Ⅵ >1/2, and in level Ⅳ>1/3 are independent risk factors for upper mediastinum lymph node metastasis(all P<0.05). The 5-year recurrence-free survival rates of the upper mediastinal lymph node metastasis group and the no upper mediastinal lymph node metastasis group were 92.3% and 94.8% respectively, and the difference was not statistically significant(P=0.307). Conclusions: For preoperative ultrasound considering the presence of lymph node metastases, enhanced neck to thorax CT should be performed routinely. When bilateral cervical lymph node metastasis is determined by CT, or endocrine tests suggest abnormally increased antibodies, attention should be paid to the upper mediastinal lymph nodes metastasis. In the course of neck dissection, if more lymph node metastases in level Ⅵ and level Ⅳ were detected, surgeons should be vigilant of the upper mediastinal metastasis. The prognosis of patients underwent complete mediastinal dissection is not significantly different from that of patients without mediastinal metastasis.

Abstract
Objective: To define the current status and analyze the medical quality of interventional therapy for patients with atrial fibrillation (AF) in China. Methods: This survey was performed in all seven large regions of China, one to three regional major medical centers were selected from each region. Medical records of patients underwent interventional therapy for AF in the year 2017 were randomly inspected. CHA2DS2-VASc score, prescribed anticoagulant after ablation, indication of left atrial appendage occlusion (LAAO), and complications in the medical records were analyzed. Results: A total of 10 800 AF catheter ablations and 447 LAAOs were performed in 17 regional medical centers in 2017. There were 10/17 centers performing AF catheter ablation<500 cases and 7/17 centers performing LAAO<20 cases. A total of 1 347 cases of catheter ablation and 160 cases of LAAO were selected for further analysis. Among all selected cases, 15.8% (238/1 505) non-valvar AF cases recorded CHA2DS2-VASc scores. The anticoagulation rate after AF catheter ablation was 98.6% (1 328/1 347), anticoagulation rate was higher than 90% in 16 out of 17 centers. The complication and severe complication rates of AF catheter ablation were 0.9% (12/1 347) and 0.4% (5/1 347), respectively. The differences of complication and severe complication rates in AF catheter ablation were similar between centers performing<500 cases and centers performing ≥500 cases (0.5% (2/413) vs. 1.1% (10/934), P>0.05; 0.5% (2/413) vs. 0.3% (3/934), P>0.05). The coincidence rate of LAAO indication was 81.3% (130/160), and the rate was higher in center performing ≥20 cases than in centers performing<20 cases (84.8% (106/125) vs. 68.6% (24/35), P<0.05). The complication and severe complication rates of LAAO were 3.1% (5/160) and 1.9% (3/160). The rate of complications in LAAO was higher in center performing<20 cases than in centers performing ≥20 cases (8.6% (3/35) vs. 1.6% (2/125), P<0.05), and there was no significant difference in severe complication rate (5.7% (2/35) vs. 0.8% (1/125), P>0.05). Conclusions: Interventional therapy for AF in China is generally standardized and safe. The overall incidence of complications post AF interventional ablation is low, the anticoagulation rate after AF catheter ablation is high, and the adherence rate of LAAO indication is fair. The indicators mentioned above vary widely among centers.

Abstract
Objective: To explore a modified CT scoring system, its feasibility for disease severity evaluation and its predictive value in coronavirus disease 2019 (COVID-19) patients. Methods: This study was a multi-center retrospective cohort study. Patients confirmed with COVID-19 were recruited in three medical centers located in Beijing, Wuhan and Nanchang from January 27, 2020 to March 8, 2020. Demographics, clinical data, and CT images were collected. CT were analyzed by two emergency physicians of more than ten years' work experience independently through a modified scoring system. Final score was determined by average score from the two reviewers if consensus was not reached. The lung was divided into 6 zones (upper, middle, and lower on both sides) by the level of trachea carina and the level of lower pulmonary veins. The target lesion types included ground-glass opacity (GGO), consolidation, overall lung involvement, and crazy-paving pattern. Bronchiectasis, cavity, pleural effusion, etc., were not included in CT reading and analysis because of low incidence. The reviewers evaluated the extent of the targeted patterns (GGO, consolidation) and overall affected lung parenchyma for each zone, using Likert scale, ranging from 0-4 (0=absent; 1=1%-25%; 2=26%-50%; 3=51%-75%; 4=76%-100%). Thus, GGO score, consolidation score, and overall lung involvement score were sum of 6 zones ranging from 0-24. For crazy-paving pattern, it was only coded as absent or present (0 or 1) for each zone and therefore ranging from 0-6. Results: A total of 197 patients from 3 medical centers and 522 CT scans entered final analysis. The median age of the patients was 64 years, and 54.8% were male. There were 76(38.8%) patients had hypertension and 30(15.3%) patients had diabetes mellitus. There were 75 of the patients classified as moderate cases, as well as 95 severe cases and 27 critical cases. As initial symptom, dry cough occurred in 170 patients, 134 patients had fever, and 125 patients had dyspnea. Reparatory rate, oxygen saturation, lymphocyte count and CURB 65 score on admission day varied among patients with different disease severity scale. There were 50 of the patients suffered from deterioration during hospital stay. The median time consumed for each CT by clinicians was 86.5 seconds. Cronbach's alpha for GGO, consolidation, crazy-paving pattern, and overall lung involvement between two clinicians were 0.809, 0.712, 0.678, and 0.906, respectively, showing good or excellent inter-rater correlation. There were 193 (98.0%) patients had GGO, 147 (74.6%) had consolidation, and 126(64.0%) had crazy-paving pattern throughout clinical course. Bilateral lung involvement was observed in 183(92.9%) patients. Median time of interval for CT scan in our study was 7 days so that the whole clinical course was divided into stages by week for further analysis. From the second week on, the CT scores of various types of lesions in severe or critically patients were higher than those of moderate cases. After the fifth week, the course of disease entered the recovery period. The CT score of the upper lung zones was lower than that of other zones in moderate and severe cases. Similar distribution was not observed in critical patients. For moderate cases, the ground glass opacity score at the second week had predictive value for the escalation of the severity classification during hospitalization. The area under the receiver operating characteristic curve was 0.849, the best cut-off value was 5 points, with sensitivity of 84.2% and specificity of 75.0%. Conclusions: It is feasible for clinicians to use the modified semi-quantitative CT scoring system to evaluate patients with COVID-19. Severe/critical patients had higher scores for ground glass opacity, consolidation, crazy-paving pattern, and overall lung involvement than moderate cases. The ground glass opacity score in the second week had an optimal predictive value for escalation of disease severity during hospitalization in moderate patients on admission. The frequency of CT scan should be reduced after entering the recovery stage.

Abstract
Our study examines the association between perceived discrimination due to race and unmet medical needs among a nationally representative sample of children in the United States. We used data from the 2016-2017 National Survey of Children's Health, a population-based cross-sectional survey of randomly selected parents or guardians in the United States. We compared results from the coarsened exact matching (CEM) method and survey-weighted logistic regression to assess the robustness of the results. Using self-reported measures from caregivers, we find that ∼2.7% of US children have experienced racial discrimination with prevalence varying significantly by race. While <1% of non-Hispanic whites have experienced some measure of racism, this increases to 8.8% among non-Hispanic blacks. Perceived discrimination was associated with significantly greater odds of unmet medical needs in the adjusted, survey-weighted multivariate-adjusted model (adjusted odds ratio [OR] = 2.4 and 95% confidence interval [CI] = 1.2, 4.9) as well as in the CEM-model estimate (OR = 2.8 and 95% CI = 1.8, 4.0). Children who have experienced perceived discrimination had higher odds of unmet medical needs. Awareness of discrimination among children may help inform future intervention development that addresses unmet medical needs during childhood.

Abstract
Liposomes are spherical vesicles with bilayer membrane structure spontaneously formed by phospholipids dispersed in an aqueous medium. Liposomes are excellent drug carrier with amphiphilic properties. Liposomes have good biocompatibility, biodegradability and no immunogenicity. Liposomes can achieve the delivery of the drug, enhance the solubility, improve the stability, reduce the toxic effect of the drug, and improve the therapeutic effect of the loaded drug. In recent years, liposome drug delivery systems have been widely used in dentistry. This article reviews the application of liposome drug delivery systems in caries, dental pulp diseases, periodontitis, implantation, oral anesthesia and oral candidiasis.

Abstract
Objective: To study clinical features of rheumatoid arthritis (RA) patients with peripheral neuropathy (PN). Methods: The clinical data of 46 RA patients with PN in the First Affiliated Hospital of Zhengzhou University from August 2012 to August 2019 were retrospectively analyzed, including clinical manifestations, laboratory and imaging results, previous treatment, treatment and clinical outcome. The other 92 RA patients without PN at the same period were selected as controls. Results: In RA patients with PN, the male to female ratio was 1∶2.1 with an average age (59.1±11.8) years. The course of RA and PN was 102.0 (19.0-156.0) months and 4.2 (0.7-5.5) months respectively. Numbness (84.8%, 39/46) and muscle weakness (21.7%, 10/46) were the most common symptoms. According to results of electromyography, polyneuropathy (60.0%, 27/46) was the predominant manifestation, followed by mononeuritis multiplex (31.1%, 14/46). Compared to RA patients, rheumatoid factor (RF) (P<0.001) and the percentage of cutaneous vasculitis (P=0.042) were higher in RA patients with PN. Logistic regression analysis revealed significant correlation between RF>178.4 IU/ml (OR=5.626, 95%CI 2.509-12.618, P<0.001) and development of PN. Paresthesia in 27 patients (58.7%, 27/46) were relieved after treatment of high dose glucocorticoid and immunoglobulins (IVIG). Twelve patients were followed up regularly and the mean duration of follow-up was 17.0(4.8-52.8)months. Paresthesia in 10 (10/12) patients were relieved compared to that at discharge, 1 (1/12) patient achieved complete remission. Conclusion: Numbness and muscle weakness are the common symptoms in RA patients with PN and polyneuropathy is the main type. RF>178.4 IU/ml is correlated with the development of PN in RA patients. Intensive treatment such as high dose glucocorticoid and IVIG are effective.

Abstract
The influence of hyperlipidemia on titanium implant osseointegration and the underlying mechanisms is not well understood. This study investigates the changes in osseointegration and explores the potential mechanisms in hyperlipidemia conditions. In vivo, specialized titanium implants were implanted in the femurs of diet-induced or genetic hyperlipidemia mice. In vitro, primary murine osteoblasts were cultured on the titanium surface in high-fat medium. Results showed that hyperlipidemia led to poor osseointegration in both types of mice in vivo, and high-fat medium impaired the osteogenic differentiation of primary osteoblasts on the titanium surface in vitro. In addition, high-fat medium caused significant overproduction of reactive oxygen species (ROS) and inhibition of the Wnt/β-catenin pathway in osteoblasts. Both N-acetyl-L-cysteine (NAC, an ROS antagonist) and Wnt3a (an activator of the Wnt/β-catenin pathway) attenuated the poor osteogenic ability of osteoblasts. In addition, NAC reactivated the Wnt/β-catenin pathway in osteoblasts under high-fat stimulation. These results demonstrate that hyperlipidemia impairs osseointegration via the ROS/Wnt/β-catenin pathway and provide support for the ROS or Wnt/β-catenin pathway as a promising therapeutic target for the development of novel drugs or implant materials to improve the osseointegration of implants in hyperlipidemic patients.

Abstract
1. Four experiments were conducted to determine the 4th limiting amino acid (AA) in maize-soybean meal-based diets. 2. Deletion assay methodology was used to quantify performance and carcase trait responses to potential deficiencies in essential and conditionally essential AA caused by reductions in dietary crude protein of maize-soybean meal-based diets from 202.9 to 186.5 g/kg. 3. The deletion of Val, Phe and Gly + Pro resulted in negative effects on live performance and carcase traits for male broilers, whereas AA deletion only affected wing weights for females with no response on live performance. 4. Further experimentation could not duplicate a response to Phe or Pro in male broilers. 5. Valine was identified as the potential 4th limiting AA in maize-soybean meal-based diets and was not found to be co-limiting with Ile.

Objective: To explore the value of "posterior approach, uncinate process priority, artery first" in laparoscopic pancreatoduodenectomy. Methods: The clinical data of 200 patients who underwent laparoscopic pancreatoduodenectomy from January 2018 to April 2019 in the Second Department of Hepatobiliary and Pancreatic Surgery, the First Hospital of Jilin University were analyzed retrospectively. Meanwhile, the advantages of "posterior approach, uncinate process priority, artery first" were analyzed. Results: Two hundred patients were treated with "posterior approach, uncinate process priority, artery first". The average total operation time was (260.2±50.1) min, sample cutting time was (86.6±18.7) min, intraoperative bleeding volume was 50 (50-100) ml, average number of lymph node dissection was (19.2±7.4), and average hospitalization time was (17.9±9.9) days. Conclusion: The "posterior approach, uncinate process first, artery first" approach not only protects the variant hepatic artery, but also allows early detection of SMA, clarifies the positional relationship between the tumor and SMA, realizes R0 resection, and reduces the amount of bleeding during operation and shortens the operation time, which is safe and feasible in clinical setting.

[PMID: 33028616 DOI: 10.1136/jech-2020-214089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 09/08/2020] [Accepted: 09/12/2020] [Indexed: 11/04/2022]
Abstract
BACKGROUND Law enforcement-related deaths of unarmed black Americans may lead black communities to distrust public institutions. Our study quantifies the impact of law enforcement-related deaths of black New York residents on the use of hospital emergency departments (ED) during 2013-2016. METHODS We used regression discontinuity models stratified by race and time period (2013-2015 and 2015-2016) to estimate the impact of law enforcement-related deaths on ED rates. Dates of deaths and media reports were from the Mapping Police Violence database. We calculated the daily overall and condition-specific ED visit rates from the New York's Statewide Planning and Research Cooperative System. RESULTS There were 14 law enforcement-related deaths of unarmed black New York residents from 2013 to 2016. In 2013-2014, the ED rate among black New Yorkers decreased by 7.7 visits per 100 000 black New Yorkers (5% less than the average ED rate) using the date of media report as the cut-off with a 2-week exposure window. No changes in ED rates were noted for black New Yorkers in 2015-2016 or for white New Yorkers in either time period. Models using the date of death followed a similar pattern. CONCLUSION The decrease in ED rates among black New Yorkers immediately following media reports of law enforcement-related deaths involving unarmed black New Yorkers during 2013-2014 may represent potentially harmful delays in healthcare. Reforms implemented during 2015-2016 might have modified the impact of these deaths. Further investigation into the population health impacts of law enforcement-related deaths is needed.

Abstract
Mental health hospitalization rates among U.S. children have been increasing locally and nationally in recent decades. Children in New York State (NYS) have also witnessed several collective traumatic events during the last two decades including the September 11, 2001, terrorist attacks (9/11), the Great Recession, and Hurricane Sandy (2012) and its aftermath. Decomposition of these rates into age, period, and cohort effects may help elucidate how large-scale collective traumatic events may be driving time trends. This study examined age-period-cohort effects in children and youth mental health hospitalizations in NYS from 1999-2013. Age effects followed a linear trend from age 5 years, B = -2.76, 95% CI [-3.48, -2.03)] up to age 15 years, B = 1.62, 95% CI [1.52, 1.73]. The largest period effects were noted in 2004, B = 0.36, 95% CI [0.28, 0.45], and in 2013, B = 0.31, 95% CI [0.15, 0.47], approximately 3 years after 9/11 and the Great Recession, respectively. The largest birth cohort effect was noted for children born in 1992-1995 (range: 0.29 for children born in 1992-0.27 for children born in 1995), suggesting that the birth cohorts who experienced the 9/11 attacks during middle childhood and the Great Recession during puberty are at increased risk of mental health hospitalizations compared to other birth cohorts.

Abstract
Background Previous research indicates that income inequality is associated with risk for mortality, self-rated health status, chronic conditions, and health behavior, such as physical activity. However, little is known about the relationship between income inequality and dietary intake, which is a major risk factor for common chronic diseases including heart disease, stroke, diabetes, and certain types of cancers. The objective of this study is to determine the association between US state income inequality and fruit and vegetable consumption among adults. Methods Cross-sectional data on 270,612 U.S. adults from the U.S. 2013 Behavioral Risk Factor Surveillance System was used. Fruit and vegetable consumption was assessed from the six-item fruit and vegetable frequency questionnaire, which is part of the Behavioral Risk Factor Surveillance System. Multilevel modeling was used to determine whether US state-level income inequality (measured by the z-transformation of the Gini coefficient) was associated with fruit and vegetable consumption adjusting for individual-level and state-level covariates. Results In comparison to men, women were more likely to consume fruits and vegetables ≥5 times daily, fruits ≥2 times daily, vegetables ≥3 times of daily, and less likely to consume fruit juice daily. Among both men and women, a standard deviation increase in Gini coefficient was associated with an increase in consuming fruit juice daily (OR = 1.07, 95% CI = 1.03, 1.11). However, among women, a standard deviation increase in Gini coefficient was associated with a decreased likelihood in meeting daily recommended levels of both fruits and vegetables (OR = 0.93; 0.87–0.99), fruits only (OR = 0.95; 95% CI, 0.92–0.99) and vegetables only (OR = 0.92; 95% CI, 0.89–0.96). Conclusions This study is one of the first to show the relationship between income inequality and fruit and vegetable consumption among U.S. adults empirically. Women’s health is more likely to be detrimentally affected when living in a state with higher income inequality.

Abstract
Objective: To investigate the rule of mediastinal lymph node metastasis of papillary thyroid carcinoma and the application of therapeutic mediastinal lymph node dissection through the sternotomy approach in the treatment of mediastinal lymph node metastasis of papillary thyroid carcinoma. Methods: All cases of papillary thyroid carcinoma with mediastinal lymph node metastasis treated through sternotomy cooperated by thoracic surgeons and head and neck surgeons from January 2006 to January 2017 in Cancer Hospital of Chinese Academy of Medical Sciences were included in this study. The distribution, metastasis rate, metastasis degree, surgical method, surgical complications and postoperative survival of patients with mediastinal lymph node metastasis were retrospectively analyzed. Results: A total of 31 patients (16 males and 15 females) with papillary thyroid cancer with mediastinal lymph node metastasis, with a median age of 46 (19-65) years, were enrolled in the group. Partial upper sternotomy was used in 28 cases, and total sternotomy was used in 3 cases. The mediastinal lymph nodes of papillary thyroid carcinoma metastasized farthest to the station 6, and the lymph node metastasis rate of each group from high to low was: 2R (61%), 1R (39%), 3A (39%), 1L (16%), 2L (10%), 4R (10%), 5 (3%) and 6 (3%). No metastasis was observed in station 3P, 4L and 7. In addition, the degree of lymph node metastasis at station 2R was the highest, reaching 35% (77/219). Extra-nodal invasion of mediastinal metastatic lymph nodes in thyroid papillary carcinoma is common (23%), easily fuses into masses (23%) and invades peripheral vascular nerves (26%). Up to 29% of blood transfusions are required during or after surgery due to oozing or bleeding (9/31). The 1-, 3-, 5-and 10-year survival rates of patients undergoing surgical treatment were 94%, 94%, 87% and 81%, respectively. Conclusion: Papillary thyroid carcinoma can metastasize to almost all mediastinal lymph nodes except station 3P, 4L and 7. Radical mediastinal lymph node dissection through sternotomy is an effective method for the treatment of mediastinal lymph node metastasis of thyroid papillary carcinoma.

Abstract
Objective: To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China. Methods: A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014. Results: Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade Ⅱ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively. Conclusions: The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.

Abstract
To investigate how Chinese rheumatologists treated patients with rheumatoid arthritis (RA). We performed a survey on the choices of first-line and second-line anti-RA therapies, prescription of methotrexate and glucocorticoids, assessment of disease activity and frequencies of follow-up at the Asia Pacific League of Associations for Rheumatology meeting 2016 in Shanghai. The majority (85.1%) of rheumatologists preferred methotrexate as first-line treatment. As alternative agents, 71.0% rheumatologists chose leflunomide or sulfasalazine. If methotrexate was not tolerable, only 8.6% rheumatologists would switch to parenteral administration. After failure of responding to methotrexate, 62.0% rheumatologists recommended to change or combine other conventional synthetic disease modifying anti-rheumatic drugs (DMARDs). Etanercept was the most popular biological option in 65.2% rheumatologists. Almost all (97.3%) rheumatologists prescribed methotrexate at an initial dose of 7.5 to 15 mg/week and 73.8% rheumatologists at a maximum of 10 to 15 mg/week. There were 49.3% rheumatologists prescribing oral glucocorticoids at first-line therapy. Surprisingly, 42.6% rheumatologists never or rarely assessed disease activity in daily work. For patients having achieved remission, 74.2% rheumatologists would follow up them every 1 to 3 months. This study suggests that most Chinese rheumatologists treat RA patients consistent with international guidelines, while the maximum dose of methotrexate, glucocorticoid as first-line treatment, assessment of disease activity and follow-up frequency are locally modified.

Abstract
Residential mobility is hypothesized to impact health through changes to the built environment and disruptions in social networks, and may vary by neighborhood deprivation exposure. However, there are few longitudinal investigations of residential mobility in relation to health outcomes. This study examined enrollees from the World Trade Center Health Registry, a longitudinal cohort of first responders and community members in lower Manhattan on September 11, 2001. Enrollees who completed ≥2 health surveys between 2004 and 2016 and did not have diabetes (N = 44,089) or hypertension (N = 35,065) at baseline (i.e., 2004) were included. Using geocoded annual home addresses, residential mobility was examined using two indicators: moving frequency and displacement. Moving frequency was defined as the number of times someone was recorded as living in a different neighborhood; displacement as any moving to a more disadvantaged neighborhood. We fit adjusted Cox proportional hazards models with time-dependent exposures (moving frequency and displacement) and covariates to evaluate associations with incident diabetes and hypertension. From 2004 to 2016, the majority of enrollees never moved (54.5%); 6.5% moved ≥3 times. Those who moved ≥3 times had a similar hazard of diabetes (hazard ratio (HR) = 0.78; 95% Confidence Interval (CI): 0.40, 1.53) and hypertension (HR = 0.99; 95% CI: 0.68, 1.43) compared with those who never moved. Similarly, displacement was not associated with diabetes or hypertension. Residential mobility was not associated with diabetes or hypertension among a cohort of primarily urban-dwelling adults.

Abstract
INTRODUCTION Population health surveys inform and demonstrate the impact of public health policies. However, the performance of such surveys in specific groups of interest (e.g., Hispanics/Latinos in a neighborhood of New York City) is rarely studied. METHOD We compared measures for obesity, hypertension, diabetes, and current smoking based on the New York City Community Health Survey (CHS, a telephone survey of New York City adults) with the Hispanic Community Health Survey/Study of Latinos (HCHS/SOL), an in-person survey of Hispanic/Latino adults in four communities in the United States (2008-2011), including the Bronx. CHS data were limited to Hispanic/Latinos living in the HCHS/SOL Bronx catchment area. RESULTS Compared with CHS, HCHS/SOL estimated higher prevalence of obesity (in HCHS/SOL, PHCHS/SOL = 45.0% vs. in CHS, PCHS = 30.6%, p < .01) and current smoking (PHCHS/SOL = 21.2% vs. PCHS = 16.2%, p < .01) but similar for hypertension (PHCHS/SOL = 33.1% vs. PCHS = 33.8%, p > .05) and diabetes (PHCHS/SOL = 15.2% vs. PCHS = 15.7%, p > .05). Stratified estimates (by age, sex, education, and Hispanic/Latino heritage) followed similar trends. CONCLUSION Our study emphasizes the importance of assessing potential bias in population-based surveys of Hispanics/Latinos and other populations of interest and highlights the complex nature of measuring health outcomes via population-based surveys.

Abstract
Objective: To summarize the clinical characteristics of cardiomyopathy complicated with ventricular thrombosis. Methods: The clinical data of inpatients suffered from cardiomyopathy complicated with ventricular thrombosis in Fuwai Hospital between January 2015 and May 2019 were analyzed retrospectively. Results: A total of 125 cases were reviewed, and 24.8% were female. Dilated cardiomyopathy was the most common disease (62.4%), followed by arrhythmogenic right ventricular cardiomyopathy (ARVC) (13.6%) and hypertrophic cardiomyopathy (11.2%). There were 74.4% thrombosis in left ventricle, 12.8% in right ventricle and 12.8% in biventricle. The proportions of right ventricle thrombosis were higher in ARVC than in other cardiomyopathies (52.9% vs 6.5%, P<0.01). The majority suffered from cardiac function New York Heart Association (NYHA) Class Ⅲ (45.6%) and class Ⅳ (39.2%). The ratio of NYHA Class Ⅳ was higher in female patients than in male ones (25.8% vs 10.6%, P<0.05). In lab detection, positive results of D-Dimer and N terminal-pro B type natriuretic peptide (NT-proBNP) accounted for 72.8% and 97.6%, respectively. There were 2.5% patients died in the hospital or discharged because of the worsening of illness, the chances were higher in female than male patients (9.7% vs 0, P<0.01). Among these patients, one succumbed to massive ischemic stroke caused by ventricular thrombus detachment under standard anticoagulation therapy. Conclusions: Dilated cardiomyopathy is the most common cardiomyopathy complicated with ventricular thrombosis. The most common location of thrombosis is left ventricle. Right ventricle thrombosis is more common in ARVC. The majority suffer from moderate or severe cardiac dysfunction. Higer proportion of female patients suffer from anemia, severe condition and poor prognosis.

Abstract
Objective: To explore the spatial-temporal distribution and epidemic characteristics of hemorrhagic fever with renal syndrome (HFRS) in Hebei province from 2005 to 2016. Methods: Records of HFRS cases reported from each county in Hebei during January 2005 to December 2016 were collected from National Notifiable Disease Surveillance System (NNDSS). Global and local spatial association statistics were used to measure the spatial autocorrelation and software GeoDa 1.2.0. Software SaTScan 9.4.1 was used to analyze spatiotemporal clusters. Software ArcGIS 10.2 was used to visualize the yearly scan results. Results: In Hebei province, a total of 8 437 human HFRS cases reported from 170 counties with an annual incidence rate of 0.99/100 000 population during 2005-2016. The peak incidence season was spring. Global spatial autocorrelation analysis on the incidence of HFRS at county-level showed that the value of Moran's I were all above 0 (P<0.05), indicating that the significant spatial cluster. The result of local indicators on spatial association (LISA) analysis revealed that identified hot spots were mainly in northeastern area, while cold spots were found in some counties of central and southern areas. Spatial-temporal scan detected that the primary cluster of HFRS incidence was mainly distributed in Qinhuangdao city and Tangshan city, including 11 counties (city/district): Beidaihe district, Haigang district, Funing district, Shanhaiguan district, Changli county, Lulong county and Qinglong Manchu autonomous county in Qinhuangdao city, and Qian'an city, Laoting county, Luanzhou city and Luannan county in Tangshan city (RR=39.64, P<0.001), during January-July in 2005. Conclusions: There were significant spatial-temporal cluster of HFRS in Hebei from 2005 to 2016. The cluster areas of HFRS were mainly in northeastern Hebei, it is necessary to strengthen the prevention and control programs of HFRS in these areas.

Abstract
Objective:The aim of this study is to systematically assess the postoperative outcomes of partial superficial parotidectomy(PSP) and superficial parotidectomy(SP) by systematic literature review and Meta-analysis, and to provide a theoretical basis for the selection of the appropriate surgical approach in clinical process. Method:Relevant studies that compared the outcomes of PSP and SP for the parotid benign tumors were searched in Pubmed, CNKI and Wanfangdata databases, and Meta-analysis was performed using software RevMan 5.0. Result:24 studies were selected for the Meta-analysis. A total of 2 795 participants were included in those studies, of whom 1 301 underwent PSP and 1 494 underwent SP. The recurrence rates for PSP and SP were 1.14%(10 of 874) and 0.6%(6 of 993), respectively. There were no statistically significant difference in recurrence rate between PSP and SP. The rates of transient facial nerve paresis for PSP and SP were 11.60%(122 of 1 052) and 27.37%(350 of 1 279), respectively. The rates of permanent facial nerve paralysis for PSP and SP were 1.04%(6 of 579) and 4.46%(31 of 695), respectively. The incidences of Frey's syndrome in PSP group and SP group were 9.20%(95 of 1 033) and 30.32%(409 of 1 349), respectively. The rate of salivary fistulafor PSP and SP were 5.38%(37 of 688) and 11.25%(65 of 578). PSP could reduce the risk for complications compared with SP. Conclusion:This systematic review with meta-analysis suggests that PSP has a similar recurrence rate as SP, but PSP can significantly reduce the postoperativecomplications.
