Swallowing function and its related factors in elderly people in welfare homes of Wenzhou City / 上海预防医学

Objective:To understand the swallowing function of the elderly in welfare homes of Wenzhou City，Zhejiang Province and to analyze the related factors of swallowing dysfunction. Methods:A total of 507 elderly people aged 60 years and over were surveyed by questionnaires in three welfare homes of Wenzhou City from January 2018 to January 2020.Hinds time-limited water drinking test was used to screen dysphagia. Multivariate unconditional logistic regression analysis was used to analyze the related factors of swallowing dysfunction. Results:The incidence of swallowing dysfunction was 26.04% （132 out of 507）. Univariate analysis showed that there were significant differences in the incidence of swallowing dysfunction among the elderly in terms of age， spouse condition， self-care ability， health status， taking sleeping pills， cerebrovascular disease， nervous system disease and depression （P<0.05）. Multivariate logistic regression analysis showed that the following factors were related to swallowing dysfunction among the elderly： age ≥80 years old， taking sleeping pills， cerebrovascular diseases， nervous system diseases and depression. Conclusion:The incidence of swallowing dysfunction in elderly people in welfare homes of Wenzhou City is high， especially those aged ≥80 years who need more attention. In addition， taking sleeping pills， cerebrovascular diseases， nervous system diseases and depression all increase the risk of swallowing dysfunction. Corresponding preventive and intervention measures should be formulated.

Prenatal diagnosis of sirenomelia by two-dimensional and three-dimensional skeletal imaging ultrasound / 华中科技大学学报（医学）（英德文版）

This study sought to evaluate the contribution of two-dimensional ultrasound (2D-US) and three-dimensional skeletal imaging ultrasound (3D-SUIS) in the prenatal diagnosis of sirenomelia. Between September 2010 and April 2014, a prospective study was conducted in a single referral center using 3D-SUIS performed after 2D-US in 10 cases of sirenomelia. Diagnostic accuracy and detailed findings were compared with postnatal three-dimensional helical computed tomography (3D-HCT), radiological findings and autopsy. Pregnancy was terminated in all 10 sirenomelia cases, including 9 singletons and 1 conjoined twin pregnancy, for a total of 5 males and 5 females. These cases of sirenomelia were determined by autopsy and/or chromosomal examination. Initial 2D-US showed that there were 10 cases of oligohydramnios, bilateral renal agenesis, bladder agenesis, single umbilical artery, fusion of the lower limbs and spinal abnormalities; 8 cases of dipus or monopus; 2 cases of apus; and 8 cases of cardiac abnormalities. Subsequent 3D-SUIS showed that there were 9 cases of scoliosis, 10 cases of sacrococcygeal vertebra dysplasia, 3 cases of hemivertebra, 1 case of vertebral fusion, 3 cases of spina bifida, and 5 cases of rib abnormalities. 3D-SUIS identified significantly more skeletal abnormalities than did 2D-US, and its accuracy was 79.5% (70/88) compared with 3D-HCT and radiography. 3D-SUIS seems to be a useful complementary method to 2D-US and may improve the accuracy of identifying prenatal skeletal abnormalities related to sirenomelia.
