Objective:To assess the risk of venous thromboembolism (VTE) and anticoagulation-related bleeding of acute critical emergency patients staying in the emergency department at least 72 h, so as to improve the ability of emergency physicians to identify risk factors of VTE and their awareness of safety prevention in these patients.Methods:Multicenter emergency internal medicine patients meeting the inclusion criteria at the same time were collected. Padua and Caprini scores were used to evaluate the risk of VTE and the HAS-BLED score was used to assess the risk of anticoagulation-related bleeding.Results:A total of 930 emergency patients from 7 medical centers were enrolled in our study from January 15, 2021 to March 15, 2021. The proportion of high-risk population with VTE was 50.22% with Padua score and 78.49% with Caprini score, respectively. The proportion of high-risk bleeding (HAS-BLED score) was 40.43%.Conclusions:More than half of the acute critical ill patients who stay in emergency department for more than 72 h are at high risk of VTE. This group of patients have a relatively low risk of anticoagulation-related bleeding.

Objective: To investigate vitamin D levels among primary and middle school students in Xicheng District, Beijing Municipality, and to examine the association of vitamin D levels with hemoglobin (Hb) and serum ferritin (SF) levels, so as to provide insights into the prevention of anemia among primary and middle school students. Methods: The first, third and fifth grade primary school students and the first grade junior high school students were sampled from Xicheng District in 2019, using the multistage stratified cluster sampling method, and students' gender, age, height, weight and Hb levels were collected. The 25-hydroxyvitamin D [25-( OH )D] was measured using electrochemiluminescence assay, and SF was detected using immunoturbidimetry. The vitamin D deficiency was determined according to the American College of Endocrinology guidelines. The associations of 25-( OH) D levels with Hb and SF levels were examined using Pearson correlation analysis and Spearman rank correlation analysis. Results: Totally 403 primary and junior high school students were investigated, including 196 boys ( 48.64% ) and 207 girls ( 51.36% ). There were 179, 114 and 110 students at ages of 6 to 8 years ( 44.41% ), 9 to 11 years ( 28.29% ) and 12 to 13 years ( 27.30% ), respectively. The mean 25-( OH )D level was ( 14.80±5.96 ) ng/mL among the study students, and there were 90 students ( 22.33% ) with severe vitamin D deficiency, 243 students ( 60.30% ) with vitamin D deficiency, 63 students ( 15.63% ) with vitamin D inadequacy and 7 students ( 1.74% ) with vitamin D sufficiency. The mean Hb level was ( 136.28±8.33 ) g/L and the median SF level (interquartile range) was 56.80 (14.36) ng/mL among the study students, respectively. The 25-( OH )D level positively correlated with Hb ( r=0.364, P<0.001 ) and SF levels ( rs=0.374, P<0.001 ), and after adjustment for age and body mass index, the 25-( OH )D still correlated positively with Hb ( r=0.157, P=0.048 ) and SF levels ( rs=0.174, P=0.022 ) . Conclusions Vitamin D deficiency is prevalent among primary and middle school students in Xicheng District, and the 25-(OH)-D levels correlate positively with Hb and SF levels. 25-( OH )-D deficiency may contribute to the development of anemia.

OBJECTIVE: To explore the genetic basis for a child with 46,XY disorders of sex development (DSD) and explore its genotype-phenotype correlation. METHODS: The child was subjected to whole exome sequencing (WES), and exons 1 to 7 of NR5A1 were subjected to multiplex ligation-dependent probe amplification (MLPA) analysis. RESULTS: The patient presented with rudimentary vulva of a female with Tanner stage 1. B-mode ultrasonography has detected ovary and uterus. The child was found to have a chromosome karyotype of 46,XY. WES revealed that the patient has harbored heterozygous deletion of exon 5 of the NR5A1 gene, which was a novel pathogenic variant inherited from the mother. No abnormality was found in the father. CONCLUSION The main symptoms of 46,XY DSD children are insufficient external genitalia masculinization, for which variants of the NR5A1 gene are an important cause. WES has improved the detection rate of genetic variants and provided a solid basis for genetic counseling of the affected families.
