RESUMO

OBJECTIVE: Elderly patients with hip fractures are frequently under anticoagulant therapy. We aimed to assess if outcomes of hip fracture patients undergoing surgical intervention differ with prior use of direct oral anticoagulants (DOAC) or Vitamin K antagonists (VKA). MATERIALS AND METHODS: PubMed, Embase, and Google Scholar were searched for comparative studies published up to June 20, 2021. Dichotomous variables were summarized using odds ratio (OR) and continuous variables using mean difference (MD). RESULTS: Fourteen studies were included. There was no difference in the time to surgery between patients on DOAC or VKA (MD: 2.50 95% CI -2.10, 7.10 I2=76% p=0.29). Number of undergoing surgeries within 48 hours was not significantly different between the two groups (OR: 0.77 95% CI 0.56, 1.06 I2=10% p=0.10). Mortality rates (OR: 0.84 95% CI 0.62, 1.14 I2=12% p=0.27), blood transfusion requirement (OR: 1.08 95% CI 0.80, 1.47 I2=30% p=0.62) and length of hospital stay (MD: 0.26 95% CI -0.70, 1.21 I2=0% p=0.60) was also not significantly different between patients on DOAC or VKA. CONCLUSIONS: There is no difference in surgical delay, early mortality, blood transfusion rates and length of hospital stay between DOAC uses and VKA users undergoing hip fracture surgery.

RESUMO

Objective: To study the expression of programmed death ligand-1 (PD-L1) in tumor cells and CD8+T lymphocytes in tumor infiltrating lymphocytes, and to analyze the correlation of PD-L1 expression with infiltration of CD8+T lymphocytes and clinicopathologic features in salivary gland lymphoepithelial carcinoma (LEC). Methods: Forty-two cases of primary salivary LECs and 21 cases of secondary salivary LECs were enrolled at the Department of Oral Pathology, Shanghai Ninth People's Hospital, Shanghai Jiaotong University between 2015 and 2017. The expression of Epstein-Barr (EB) virus, PD-L1 and CD8 was examined using chromogenic in situ hybridization (CISH) and immunohistochemistry (IHC) staining. The data were analyzed using SPSS 23.0 software package. Results: EB virus was detected in 61 cases (61/63, 96.8%), including 42 (42/42, 100%) primary LECs and 19 (19/21, 90.5%) secondary LECs. The PD-L1 positive rate (score ≥1) was 97.6% (41/42), and its high-expression rate (score ≥20) was 78.6% (33/42) in primary LECs. The PD-L1 positive rate (score ≥1) was 71.4% (15/21), and its high-expression rate (≥20) was 38.1% (8/21) in secondary LECs. However, the PD-L1 positive rate (score ≥1, P=0.004) and high-expression rate (score ≥20, P=0.001) in primary LECs were higher than those in secondary LECs. There was no difference in the infiltration degree of CD8+T lymphocytes between primary and secondary LECs. There was a significant correlation between the expression of PD-L1 and CD8 in primary LECs (P=0.001) and in secondary LECs (P=0.048), respectively. Conclusions: There is PD-L1 expression in primary and secondary salivary LECs, while the expression rate is higher in primary LECs than secondary LECs. The combination of PD-L1 expression and CD8+T lymphocytes' presence suggest that most LEC patients might be responsive to immunotherapy, and primary LECs might be more significantly responsive than secondary LECs.

RESUMO

Objective: To evaluate the safety and efficacy of vemurafenib in the treatment of BRAF(V600E)-mutated Erdheim-Chester disease (ECD) . Methods: We retrospectively analyzed the clinical data, response rate, adverse events and survival of 12 patients with ECD treated with vemurafenib from March 2015 to October 2020 in Peking Union Medical College Hospital. Results: Of 12 patients [7 males and 5 females, median age = 51.5 (range, 32-66) years old], the median number of organs involved was 6 (range, 4-8) , and the median treatment duration of vemurafenib was 11 (3-60) months. All patients had improvement of clinical symptoms, of which 2 cases were completely relieved, and 10 cases were partially relieved. Seven patients evaluated by (18)F-FDG-positron emission tomography/computed tomography achieved a metabolic response, including 2 patients with a complete metabolic response and 5 patients with a partial metabolic response. The common adverse events in the overall cohort were grade 1 to 2 (Common Terminology Criteria for Adverse Events 5.0) , including skin rash (58.3%) , arthralgia (25.0%) , and digestive tract reactions (16.7%) . The median follow-up time was 13.5 (3-60) months. One patient with central nervous system involvement died due to a cerebrovascular event, and one patient relapsed 10 months after drug withdrawal. The estimated 2-year overall survival rate and 2-year progression free survival rate were 88.89% and 66.67%, respectively. Conclusions: Vemurafenib is safe and effective in the treatment of BRAF(V600E)-mutated ECD.

RESUMO

Solid-state fermentation has been used to improve the nutritive value of feed ingredients. In the present study, we investigated the effects of solid-state fermented wheat bran (FWB) on growth performance and apparent digestibility in broiler chickens. We measured the growth performance (ADFI, ADG, feed conversion, livability, and European performance efficiency factor) over 38 d in chicks fed a corn-soybean meal control diet (CON) or CON plus wet FWB (25 g/kg [T1]; 50 g/kg [T2]); or T1 plus 3 g/kg (T3); or T2 plus 6 g/kg (T4) soybean oil). The same diets were used to determine nutrient availability in chicks aged 20 d. Regression equations for AME and AMEn were obtained using 20-day-old chicks fed either the corn-soybean meal basal diet only or basal diet partially substituted with 50, 150, or 300 g/kg DM FWB. Diets containing 25 or 50 g/kg wet FBW did not affect the growth performance of broiler chickens, nor the apparent DM, energy, and nitrogen digestibility of the feeds, compared with the control diets (all P > 0.05). Further supplementation with oil did not improve the growth performance of broiler chickens compared with controls or chickens fed FBW. However, chickens fed diets containing soybean oil (T3 or T4) had lower (P = 0.005 and P = 0.040, respectively) apparent DM and energy digestibility than the control and FWB groups. The regression equations for AME and AMEn with the substitution of FWB produced values of 1,854.3 and 1,743.9 kcal/kg DM, respectively, and the equations were Y = 1854.3X + 52.7 (R2 = 0.971, n = 24, P < 0.001), and Y = 1743.9X + 44.6 (R2 = 0.978, n = 24, P < 0.001), respectively. Supplementation with wet FWB did not affect the growth performance of broiler chickens. Therefore, FWB is a suitable feed component for broilers.

RESUMO

Objective: To compare the prognostic value of four prognostic models in predicting time to first treatment (TTFT) in patients with Binet A Chinese chronic lymphocytic leukemia (CLL) . Methods: This retrospective analysis included one hundred and ten patients with Binet A CLL, initially diagnosed in the First Affiliated Hospital of Nanjing Medical University (Pukou CLL center) from June 2009 to January 2020. Risk stratification was conducted according to IPS-E, CLL-IPI, CLL1-PM, and Barcelona-Brno prognostic models. Results: Among 110 patients with Binet A CLL patients, the median age was 58 (25-84) years. The median follow-up time was 35 (4-189) months, and 57 (51.8%) patients met the indication for treatment due to symptomatic disease progression during follow-up. Log-rank analysis of nine variables was conducted involving age, Rai stage, absolute lymphocyte count (ALC) , lymph node size, lymphocyte doubling time (LDT) , ß(2)-Microglobulin, IGHV status, TP53, and Del (11q) . Additionally, Rai Ⅰ-Ⅲ, ALC>15×10(9)/L, palpable lymph node size ≥1cm, ß(2)-Microglobulin>3.5 mg/L, unmutated IGHV, TP53 mutation or deletion, and 11q deletion were independent risk factors of TTFT. Predictive value of each model was assessed by Harrel C-index and Akaike information criterion (AIC) with CLL1-PM (C-index=0.736, AIC=777) , followed by CLL-IPI (C-index=0.722, AIC=933) , IPS-E (C-index=0.683, AIC=1004) , and Barcelona-Brno prognostic model (C-index=0.663, AIC=986) . Conclusion: All four prognostic models effectively predicted TTFT. IPS-E might be an ideal model to guide clinical surveillance because of its easy accessibility and low expenses in routine clinical practice. Therefore, for patients receiving fluorescence in situ hybridization (FISH) and next-generation sequencing (NGS) examination at diagnosis, CLL-IPI or CLL1-PM could be applied to evaluate their prognosis more comprehensively.

RESUMO

Oscillatory magnetoresistance measurements on graphene have revealed a wealth of novel physics. These phenomena are typically studied at low currents. At high currents, electrons are driven far from equilibrium with the atomic lattice vibrations so that their kinetic energy can exceed the thermal energy of the phonons. Here, we report three non-equilibrium phenomena in monolayer graphene at high currents: (i) a "Doppler-like" shift and splitting of the frequencies of the transverse acoustic (TA) phonons emitted when the electrons undergo inter-Landau level (LL) transitions; (ii) an intra-LL Mach effect with the emission of TA phonons when the electrons approach supersonic speed, and (iii) the onset of elastic inter-LL transitions at a critical carrier drift velocity, analogous to the superfluid Landau velocity. All three quantum phenomena can be unified in a single resonance equation. They offer avenues for research on out-of-equilibrium phenomena in other two-dimensional fermion systems.

RESUMO

Objective: To compare the efficacy and safety of ticagrelor and clopidogrel in elderly Chinese patients with acute coronary syndrome (ACS) underwent percutaneous coronary intervention (PCI) in the real world. Methods: This study is a post-hoc analysis of a single center, retrospective cohort study. Between March 2016 and March 2018, elderly (age≥65) ACS patients who underwent PCI in the General Hospital of Northern Theater Command were included in the study. The patients were grouped according to P2Y12 receptor inhibitor. The primary endpoints of this study were ischemic events during the 2-year follow-up, which were defined as the composite of cardiac death, myocardial or stroke. The secondary efficiency endpoints included all-cause death and BARC 2, 3, 5 bleeding events. Results: A total of 4 022 elderly (mean age: (71.5±5.3) years) ACS patients were included in this study. Based on the choice of P2Y12 receptor inhibitor, patients were divided into clopidogrel (n=3 201) and ticagrelor (n=821) groups. Incidences of ischemic events (3.2% (26/821) vs. 5.6% (179/3 201), P=0.005) at 2 years were significantly lower in ticagrelor group compared to clopidogrel group. BARC 2, 3, 5 bleeding events (1.7% (14/821) vs. 1.6% (52/3 201), P=0.818) were comparable between the two groups. The incidence of all-cause death (1.5% (12/821) vs. 4.1% (132/3 201), P=0.005) were also lower in the ticagrelor group compared to the clopidogrel group. Clinical outcomes were consistent after adjusting for confounding factors, the incidence of ischemic events (HR= 0.637, 95%CI 0.409-0.991, P=0.046) and all-cause mortality (HR=0.402, 95%CI 0.213-0.758, P=0.005) was significantly lower in the ticagrelor group compared with the clopidogrel group. Risk of BARC 2, 3, 5 bleeding events were similar between the two groups (HR=0.957, 95%CI 0.496-1.848, P=0.897). Conclusion: In real-world clinical practice, for elderly patients with ACS undergoing PCI, ticagrelor use might reduce the incidence of long-term ischemic events and all-cause death without increasing the risk of bleeding.

RESUMO

Objective: To explore the relationship between self-rated health status and risk of stroke in Chinese adults. Methods: Data was collected from the Chronic Disease Risk Factor Surveillance in China (2010) as baseline. A total of 60 follow-up monitors (25 urban and 35 rural) in 11 provinces were selected. A total of 36 195 participants without prior cardiovascular diseases were followed and investigated 27 441 people in 2016 and 2017. Cox proportional hazard regression model was used to analyze the self-assessed health status and stroke onset hazard ratio (HR), further conducted several subgroup analyses by demographic characteristics such as age and gender, and sensitivity analysis was performed by excluding death and baseline diabetes. Results: A total of 26 699 study subjects were included according to the inclusion criteria. We identified 1 332 stroke cases (32 subarachnoid hemorrhage, 197 cerebral hemorrhage, and 1 149 cerebral infarction) during an average of 6.4 years (171 431.1 person-years) of follow-up, and the incidence density was 7.77/1 000 person-years. After adjusting the related factors, the risk of stroke in participants with poor self-related health increased by 68% (HR=1.68, 95%CI:1.22-2.32) and the risk of ischemic stroke increased by 47% (HR=1.47, 95%CI:1.05-2.05), with a reference of excellent ones. In subgroup analysis, only age and BMI had an effect-modifying effect on the association between self-rated health and risk of stroke. Only age and dyslipidemia had an effect-modifying effect on the association between self-rated health and ischemic stroke risk (interaction P<0.05). The results of the sensitivity analysis were consistent with the results of the total population. Conclusion: People with poor self-assessed health, especially for those who were overweight/obesity with poor self-assessed health or age less than 60 or dyslipidemia are at increased risk of stroke and ischemic stroke and should be targeted for intervention.

RESUMO

Antibiotic resistance (AR) is a severe and fast-growing public health challenge with rapid globalization, especially in China. Although some monitoring systems were established in different fields, fragmentation of information failed to show the overall trend and spread of AR. It is necessary to establish a national monitoring system to reveal the occurrence, development, and spread of AR. The new AR monitoring system needs an updated analysis indicators system. We intend to recommend a new analysis indicators system for AR was constructed and applied to AR data monitoring and analysis for humans, animals, the environment, and foods. After investigating and analyzing the 5 Chinese major AR monitoring systems and literature, we have formulated 15 AR monitoring analysis indicators and initially established an evaluation system for the country's new AR monitoring system.

RESUMO

Objective: To understand the influence and lag effect of meteorological factors on the incidence of hand, foot and mouth disease (HFMD) in Shijiazhuang. Methods: The daily incidence data of HFMD in Shijiazhuang during 2017-2019 were collected from Chinese Information System for Disease Control and Prevention. The hourly meteorological data were collected form meteorological stations of Shijiazhuang of Chinese meteorological data network. The distributed lag nonlinear model was built for statistical analysis by software R 3.6.2. Results: When the daily average temperature was 15-26 ℃, the risk of incidence of HFMD increased at lag 3-6 days. However, the risk was highest when the temperature was 25 ℃ at lag 3 days (RR=1.03,95%CI:1.00-1.06). When the daily average relative humidity was more than 80%, the risk of incidence of HFMD increased at lag 5-18 days. However, the risk was highest at lag 9 days (RR=1.04, 95%CI: 1.02-1.06).When the daily average air pressure ranged from 999 hPa to 1 007 hPa, the risk of incidence of HFMD increased at lag 5-8 days. However, the risk was highest at lag 6 days (RR=1.01, 95%CI: 1.00-1.02).When the daily average precipitation ranged from 15 to 32 mm, the risk of incidence of HFMD increased at lag 3-18 days. However, the risk was highest at lag 6 days (RR=1.11, 95%CI: 1.02-1.19). Conclusions: Meteorological factors increased the risk of incidence of HFMD such as higher daily average temperature (15-26 ℃), higher daily average humidity (>80%), lower daily average air pressure (999-1 007 hPa) and higher daily average precipitation (15-32 mm) in Shijiazhuang during 2017-2019. They were all correlated with the incidence of HFMD with certain lag days. It is suggested to use these meteorological indicators for the early warning of HFMD.

RESUMO

Objective: To understand the capacity building needs on social organizations providing HIV prevention and treatment services for female sex workers (FSW). Methods: Questionnaires and interview were conducted with the heads of social organizations participating in China AIDS Fund for Non-Governmental Organizations (CAFNGO) project 2017-2018. Data from the CAFNGO's information system were compiled and analyzed using Excel 2016 and SPSS 25.0 software. The distribution of social organizations, availability of funds, and social organizations' needs for capacity building were analyzed. Results: Nationwide, 184 social organizations were involved in project '2017-2018 CAFNGO's FSW field work'. Out of which, 156 answers were valid. Social organizations that participated in the implementation of fund projects were mainly concentrated in the western region, accounting for 44.0% (81/184), with Sichuan, Guangxi, and Yunnan being the majority. However, the eastern part received the most financial support. Social organizations expressed the highest demand for project data collection and analysis, accounting for 68.6% (107/156). Items on risk analysis, response, and quality control project ranked the second, accounting for 64.1% (100/156). Results showed that statistically significant differences were seen on capacity building needs among social organization leaders with different levels of training on management of planning and finance of the project (χ2=5.78,P=0.016;χ2=8.99,P=0.003). Conclusions: Currently, the number of social organizations and the related fund provision concerning HIV prevention and control among FSWs were not consistent in China. Thus, it is necessary to encourage, guide, and support the development of social organizations and satisfy social organizations' needs on capacity-building and planning.

RESUMO

One of the most common birth defects is cleft palate only (CPO) of which non-syndromic cleft palate only (NSCPO) accounts for 50%. NSCPO is a complex disease where multiple genes and environmental factors contribute to its risk. Unlike non-syndromic cleft lip with or without cleft palate (NSCL/P), previous genome-wide association studies only identified a few common genetic variations achieving genome-wide significance. This review summarizes the recent findings on genetic epidemiology of NSCPO. According to the current evidence, the candidate genes are divided into three categories: candidate genes with strong evidence, candidate genes with suggestive evidence, and candidate genes with inadequate evidence. The findings of epigenetic studies, the next generation sequencing studies, interaction analysis on NSCPO are also reviewed.

RESUMO

Objective: To systematically evaluate the methodological quality of screening guidelines for upper gastrointestinal cancer (including esophageal cancer and gastric cancer) both at home and abroad, and provide reference for the update of upper gastrointestinal cancer screening guidelines in China. Methods: Original articles and grey literature published as of 31th Aug 2020 were retrieved using Chinese databases (CNKI, Wanfang, China Biomedical Literature Database and China Guideline Clearinghouse), PubMed, The Cochrane Library and Embase, as well as those from International Agency for Research on Cancer and the International Guide Collaboration Network. The inclusion criteria were being independent guidelines/recommendation documents for upper gastrointestinal cancer screening and meeting the definition of the institute of Medicine, USA. The exclusion criteria were being guideline abstracts, interpretation and evaluation literature, duplicate publications, updated original guidelines, and clinical treatment or practice guidelines for esophageal or gastric cancer. Appraisal of Guidelines for Research and Evaluation (AGREE Ⅱ) and Reporting Items for Practice Guidelines in Healthcare (RIGHT) were used to compare and evaluate the quality and reporting standard of esophageal or gastric cancer screening guidelines. Results: A total of 6 esophageal cancer screening guidelines and 5 gastric cancer screening guidelines were included. The results of the AGREE Ⅱ quality evaluation showed that the overall quality of eleven guidelines varied, including two guidelines recommended for "A", one for "B", five for "C" and three for "D". The guidelines had higher scores in the areas of scope and purpose, and clarity. The esophageal cancer screening guidelines had different scores in the areas of rigor and independence. The gastric cancer screening guidelines generally had low scores in the areas of participants and application. The RIGHT evaluation results showed that the quality of eleven guidelines should be improved. The six items with poor report quality were background, evidence, recommendations, review and quality assurance, funding and conflict of interest statement and management and others. Conclusion: The quality of the included upper gastrointestinal cancer screening guidelines is general, and the standardization needs to be strengthened.

RESUMO

Objective: To explore the relationship between body mass index (BMI), waist circumference (WC) and the risk for ischemic stroke in adults in China. Methods: A total of 36 632 adults were selected from 60 surveillance areas (25 urban surveillance areas and 35 rural surveillance areas) in China Chronic Disease Surveillance Project in 2010 for a follow up study from 2016 to 2017 based on the baseline data in 2010. The follow up was completed for 27 762 adults. Cox proportional hazard regression model was used to analyze the association of body mass index and waist circumference with the risk for ischemic stroke in different populations. The death and hypercholesterolemia cases were excluded by sensitivity analysis. Results: A total of 26 907 adults were included in the analysis. During the follow up period, 1 128 ischemic stroke events were observed (491 in men and 637 in women). After adjusting the related confounding factors and taking normal BMI/normal WC group as the reference, the risk for ischemic stroke increased by 50% in normal BMI/abdominal obesity group (HR=1.50, 95%CI:1.07-2.08), 51% in overweight/abdominal obesity group (HR=1.51, 95%CI:1.20-1.91), 46% in obesity/abdominal obesity group (HR=1.46, 95%CI:1.09-1.96), and 63% in normal BMI/abdominal obesity group (HR=1.63, 95%CI:1.12-2.38), 56% in overweight/abdominal obesity group (HR=1.56, 95%CI: 1.20-2.03) and 45% in obesity/abdominal obesity group (HR=1.45, 95%CI: 1.05-2.01) respectively in men and in men with CVD risk factors. There was no increased risks in the overweight/normal WC group. The risk increased by 40% in overweight/abdominal obesity group (HR=1.40, 95%CI:1.15-1.72) and 46% in obesity/abdominal obesity group (HR=1.46, 95%CI:1.16-1.83), and 35% in overweight/abdominal obesity group (HR=1.35, 95%CI:1.08-1.69) and 30% in obesity/abdominal obesity group (HR=1.30, 95%CI:1.01-1.67) respectively in women and women with CVD risk factors. There were no risk increases in overweight/normal WC group and normal BMI/abdominal obesity group. Sensitivity analysis results showed no change. Conclusion: Overweight/obesity with abdominal obesity or abdominal obesity alone could increase the risk for stroke in men, and overweight/obesity with abdominal obesity could increase the risk for ischemic stroke in women; suggesting that BMI and WC should be used jointly to evaluate obesity in population for weight control to prevent ischemic stroke.

RESUMO

Objective: To analyze the mortality in HIV/AIDS cases aged ≥15 years under antiretroviral treatment (ART) in Henan province from 2002 to 2019, and provide evidence for reducing the mortality rate of HIV/AIDS and AIDS prevention and treatment. Methods: Data of HIV/AIDS cases aged ≥15 years who received ART in Henan from 2002 to 2019 were obtained from "Infectious Disease Surveillance System - Basic Information on AIDS Prevention and Control". In this retrospective study, Cox proportional risk model was used to analyze the influencing factors for HIV/AIDS related deaths. Software SPSS 23.0 was used for statistical analysis. Results: From 2002 to 2019, a total of 72 986 HIV/AIDS cases aged ≥15 years received ART, in whom, 16 634 died during this period. Most of the death cases were aged ≥40 years old (68.5%,11 393/16 634), males (62.6%,10 419/16 634), infected through blood-borne transmission (71.7%,11 927/16 634), and farmers or migrant workers (91.7%,15 249/16 634). Most of the deaths were due to AIDS related diseases (73.7%, 12 261/16 634), and the case fatality rate was 16.8% (12 261/72 986). A total of 34.6% (4 237/12 261) of HIV/AIDS cases died of AIDS-related diseases in the first year of ART, and the cumulative survival rates at 10 and 18 years of ART were 78.3% and 71.8%, respectively. The proportion of the HIV/AIDS cases with baseline CD4+T lymphocyte (CD4) counts <200 cells/µl at age 15 years when ART started was 45.5% (30 432/66 898). Cox proportional risk regression model showed that, compared with the cases with baseline CD4 counts ≥350 cells/µl, the risk of death was 1.78 times higher than in the cases with CD4 counts <200 cells/µl (95%CI: 1.64-1.94) and 1.24 times higher in the cases with CD4 counts ≥200 cells/µl (95%CI: 1.13-1.36), respectively. The risk of death in symptomatic cases at baseline survey was 1.25 times higher than that in asymptomatic cases (95%CI: 1.16-1.35). The cases with a latest viral load ≥1 000 copies/ml had 7.09 times higher risk of death than those with a last viral load<1 000 copies/ml (95%CI: 6.65-7.54). Conclusions: The majority of HIV/AIDS deaths occurred in the cases aged ≥15 years receiving ART in Henan province during 2002-2019, who were infected through blood-borne transmission and farmers/migrant workers, and AIDS-related diseases were the main causes of the deaths. With the gradual implementation of ART policy, the high survival rate in HIV/AIDS cases can be maintained for a long time in Henan. To reduce the case fatality rate and improve the quality of life of HIV/AIDS patients, CD4 counts test should be further strengthened and eligible HIV/AIDS patients should be covered by standard ART in a timely manner.

RESUMO

Objective: To explore the association of maternal anxiety with congenital heart disease (CHD) in offspring. Methods: A case-control study design was used in this study. The data were collected in Shaanxi province from January 2014 to December 2016. Neonatal information is provided through specialized hospitals or institutions. Logistic regression model with adjustment for confounding factors was established to analyze the association between maternal perinatal anxiety and CHD in offspring. Meanwhile, subgroup analysis was carried out to explore its stability. Results: Our study included 2 429 subjects, consisting of 773 cases and 1 656 controls. Women with anxiety during pregnancy accounted for 10.3% in the case group, while 7.8% in the control group. After adjusting for confounding factors, the level of maternal anxiety during pregnancy was positively correlated with CHD in the offspring (OR=1.04, 95%CI: 1.01-1.07). The risk of CHD in the offspring of mothers with anxiety during pregnancy was 1.43 times higher than that in those whose mothers had no anxiety (OR=1.43, 95%CI: 1.00-2.05). Conclusion: Maternal anxiety during pregnancy is probably a risk factor for congenital heart disease in offspring.

RESUMO

Avian influenza virus (AIV) is a kind of zoonotic virus which can cause acute respiratory infectious diseases. Since the report of the world's first human infection case of avian influenza A (H7N9) virus in China in 2013, close attention has been paid to the virus. AIV spreads widely around the world, and human infection with different types of AIV continues to occur, causing huge economic losses. At present, there are no specific treatment and drugs against the disease, and vaccination is considered as the most promising and effective method to control the human infection with AIV. So far, there are many kinds of veterinary and human vaccines for H7N9 AIV, among which four types of human H7N9 AIV vaccines have entered the clinical trial stage, including virus-like particles vaccine, attenuated live vaccine, inactivated vaccine and DNA vaccine, which have shown good safety and immunogenicity. However, the true efficacies of the AIV vaccines remain unknown because no human vaccines are currently available in the market. In addition, although the existing influenza vaccine has good safety and immunogenicity in the human population, there is no cross-antibody response to H7N9 AIV. This paper summarizes the research progress of AIV etiology and epidemiology, the occupational exposure population investigation, the infection prevention and control strategies, and H7N9 AIV vaccine and H7N9 AIV anthropogenic monoclonal antibody, and discuss the remained problems, challenges and future trends in the research of AVI to improve the understanding of the disease and the prevention and control of global spread of AIV.
