RESUMO
Objective:To assess the characteristics and correlation of motor development in preterm infants of different gestational weeks by using the Test of Infant Motor Performance (TIMP) method, and to develop better individualized early interventions based on TIMP test results.Methods:A prospective study involving 43 full-term healthy infants and 77 preterm followed up in 3201 Hospital from June 2019 to July 2021 was conducted.Preterm infants were divided into the early preterm group (39 cases) and late preterm group (38 cases) according to their gestational age at birth.TIMP assessment was performed at the gestational age of 40 weeks and the corrected age of 16 weeks after birth.Similarly, the full-term healthy infants were assessed by TIMP at the postnatal age of 16 weeks.The differences between groups were investigated using ANOVA or Mann- Whitney rank sum test.Correlations were analyzed by the Pearson correlation method. Results:There were no significant difference in TIMP scores between early and late preterm infants at the gestational age of 40 weeks [(65.74±6.52) scores vs.(66.96±8.51) scores] and the corrected age of 16 weeks [(101±10) scores vs.(104±8) scores] (all P>0.05). TIMP scores in the full-term healthy group at the corrected age of 16 weeks [(108±10) scores] differed significantly from those of early and late preterm infants ( P<0.05). Compared with full-term infants, early and late preterm infants had lower TIMP scores in observation, supine position, and supine turning (all P<0.05), but a higher TIMP score in standing position ( P<0.05). For both early and late preterm infants, TIMP scores at the gestational age of 40 weeks were significantly positively correlated with those at the corrected age of 16 weeks ( r=0.565, 0.302, all P<0.01). Conclusions:There were significant differences in motor development between preterm infants of different gestational ages and term infants, which had guiding significance for early intervention.English version TIMP could play a positive role in promoting individualized follow-up and early intervention of preterm infants in China.
RESUMO
Medical workplace violence (WPV) has become an alarming phenomenon in China. Few studies exist concerning how this is represented in the news. This study investigated the prevalence, characteristics, and causes of WPV from major news portals and medical websites in China, to provide a direction on the prevention and control of this issue. Quantitative content analysis was used to examine Chinese news portals and medical websites from 2013 to 2017. 235 valid reported cases were found. The number of incidents peaked in 2015, during the summer. Most cases occurred in the mid-eastern region of mainland China, in tertiary hospitals, and in the emergency department. The perpetrators were mainly individual males from the young adult or middle-aged groups. The major cause of medical WPV was dissatisfaction with treatment and referral. In conclusion, the development of prevention and control strategies is crucial and should be in accordance with the evidence from the research conducted.
RESUMO
<p><b>OBJECTIVE</b>To evaluate the clinical application of multi-planar reformation (MPR) for the diagnosis of superior semicircular canal dehiscence syndrome.</p><p><b>METHODS</b>A retrospective study was conducted on 9 patients who were diagnosed with SSCD syndrome in the Otology and Skull Base Surgery group of Fudan University. Three radiologists analyzed all the patients' 0.75 mm-collimated axial and coronal images and 0.75 mm-collimated MPR images, and they came up with the same results.</p><p><b>RESULTS</b>There were 18 superior semicircular canal in the 9 patients, of whom 9 were intact and 9 were defective. All the defective superior semicircular displayed a definite dehiscence in all the MPR images, which indicated the sensitivity was 100%; however, 7 of the 9 defective superior semicircular canal were diagnosed as dehiscence in axial images, while 8 of the 9 were diagnosed in coronal images, but the sensitivities were 77.8% and 88.9% respectively. The results of the other 9 with intact superior semicircular canal displayed in the MPR, axial, and coronal images were also different. In the MPR images, they all displayed definite intact roof over the superior semicircular canal. There were 2 dehiscence in all axial and coronal images, and the specificities were 77.8%.</p><p><b>CONCLUSION</b>The MPR image is more useful in diagnosis of superior semicircular canal dehiscence syndrome than that of the routine axial and coronal images.</p>
