ABSTRACT
Objective To explore optimal initial the best screening time for newborns with different delivery methods using AABR.Methods A total of 550 newborns who were born from August 1, 2016 to October 31, 2016 at our hospital participated in the study.AABR was used to accomplish the initial hearing screening.The newborns were divided into 2 groups according to the delivery methods.There were each 100 neonates born in vaginal during 0.05).There were 250 newborns in cesarean section, the pass rate of 24~48 h after birth group was significantly higher than that in 24 h group (83.00% vs 68.00%,x2=4.437, P=0.04<0.05), and significantly lower than that of 48~72 h group (94.00% vs 83.00%,x2=5.944, P=0.02<0.05).Conclusion Taking into account of hospitalization time, the screening time for the vaginal delivery newborn hearing screening can be advanced to 24~48 h after birth with the application of AABR, but not for the cesarean section group.
ABSTRACT
Objective To explore the prevalence of physical activity time ＜1 hour and related factors in students aged 9-22 years in China.Methods A total of 220 159 students (110 039 boys and 110 120 girls) aged 9-22 years who completed the questionnaire of physical activity and lifestyle behaviors were selected from "2014 National Physical Fitness and Health Surveillance" for the current study.All the participants were divided into 2 groups,i.e.physical activity time ＜ 1 hour and physical activity time ≥ 1 hour according the suggestion of Central Government,stratified by age and gender.x2 tests were used to compare the difference in the prevalence of physical activity time ＜ 1 hour between boys and girls in every age groups.Univariate and multivariate log-binomial regression models were used to explore the factors that influenced the prevalence of physical activity time ＜ 1 hour.Results The boy's prevalence of physical activity time ＜1 hour was 73.3％,with the lowest (57.0％) in 9-years-old group,and highest (82.5％) in 18 years old group.The girl's prevalence of physical activity time ＜ 1 hour was 79.1％,with the lowest (60.1％) in 9-years-old group,and highest (89.8％) in 21 years old group.Overall,The prevalence of physical activity time ＜ 1 hour was significantly higher in girls than in boys (P＜0.001),and the prevalence were significantly higher in girls than in boys in all the age groups (P＜0.001),and it was observed that the prevalence of physical activity ＜ 1 hour increased with age in both boys and girls (P＜0.001).Multivariate log-binomial regression model found that being girl (PR=1.05,95％CI:1.05-1.06),parents' disliking children to participate physical activity (PR=1.08,95％CI:1.07-1.09),heavy homework (PR=1.13,95％CI:1.12-1.14),long homework time (PR=1.08,95％CI:1.07-1.08),long time spending on electronic screen watching (PR=1.01,95％CI:1.00-1.01) and disliking physical class (PR=1.11,95％CI:1.10-1.12) could be the risk factors for physical activity time ＜ 1 hour,however,living in rural area (PR=0.99,95％CI:0.98-0.99) and no supporting from parents for children to participate physical activity (PR=0.99,95％CI:1.98-1.00) could be the protective factors,but no consistent association with the time of TV watching was observed (P=0.226).Conclusions The prevalence of physical activity time ＜ 1 hour was high in students aged 9-22 years in China.Female,parents;disliking children to participate physical activity,heavy homework,long homework time,long electronic screen watching time and disliking physical class might be the risk factors.

ABSTRACT
Objective To explore the best time period of pulse oximetry in congenital heart disease (CHD) screening. Methods Totally 5433 newborns delivered or treated in Ningbo Women and Children’s hospital were enrolled in the study. Cardiac color ultrasound was used to arrive diagnosis and every screening time period (0?~?24 h、24 h?~?48 h、48 h?~?72 h) was analysed. Results Among the three time periods: the sensibility was in the range of 54.72%?~?67.92%, specificity was 99.11%?~?99.61%, false negative rate was 32.08%?~?43.40%, false positive rate was 0.39%?~?0.89%, Youden index was 0.54?~?0.68, coincidence rate was 98.67?~?99.30, and kappa was 0.44?~?0.65. Conclusion The best screening time is the period between 48h and 72 h after birth.
ABSTRACT
The aims of this study are (1) to determine the scattered radiation dose levels in routine fluoroscopy procedures and (2) to compare them with the equivalent chest x-rays and also (3) to monitor common techniques and radiation safety measures taken by the medical officers. The study covered a sample of 105 fluoroscopic procedures performed by 18 medical officers. Each officer wore a personal pocket dosimeter inside the lead gown during each procedure. A digital dosimeter was placed near the detector of the fluoroscopy unit while a survey meter was positioned at the control panel area to record the dose levels. There were 14 types of examination included in this study. The total number of images captured was found to be the highest in barium swallow examination with 115 images, almost five times higher compared to the common practices. The longest screening time was observed in barium enema examination which is 9.15 seconds. The median of the scattered dose level was the highest in barium meal examination (165.50 μSv) which is equivalent to 8.28 times of average dose impart by chest x-ray examinations. The number of images and the length of screening time depend on the competency levels of the medical officers. They capture as many images as possible to avoid missing any abnormalities, therefore it will always be better if the fluoroscopist is consulted during each case. They should also consistently practice essential protection by minimizing exposure time, maximizing distance from the source tube and utilizing the radiation shielding.
