Objective To develop a multidisciplinary nursing program for Prader-Willi syndrome with spinal deformity and evaluate its effectiveness in clinical practice. Methods In July 2016, a multidisciplinary collaborative team was established before the treatment of children with Prader-Willi syndrome complicated with spinal deformity. For the nursing difficulties in the perioperative period, relevant literature was consulted, and a multidisciplinary collaborative nursing plan was formulated, which included nutrition management and blood glucose control, management of obstructive sleep apnea hypopnea syndrome, behavioral intervention related to mental change, and early identification and management of complications. The developed multidisciplinary collaborative nursing program was applied to three children with Prader-Willi syndrome complicated with spinal deformity in Peking Union Medical College Hospital from July 2016 to October 2018, and their postoperative recovery was evaluated. Results One child had inguinal skin ulceration when admitted to hospital, which was significantly improved after active treatment. The perioperative blood glucose level control of the three children was satisfactory, and there was no postoperative gastrointestinal dysfunction, deep wound infection, respiratory complications, internal fixation failure or other complications, and no asphyxia, fall, loss, or other adverse events. The follow-up compliance after discharge was 100%. Conclusions Multidisciplinary collaboration programs can escort patient’ safety and promote their recovery, improve the professional level of nursing staff, and reflect the nursing value. As a working mode, it can be further popularized and used for reference in the nursing of other difficult diseases.
Breast cancer is a malignant tumor with the highest incidence and mortality rate among women worldwide. Early screening and standardized diagnosis and treatment of breast cancer are conducive to improving the survival rate of patients. Breast magnetic resonance imaging (MRI) plays a crucial role in the screening of high-risk populations, diagnosis, staging, and treatment efficacy evaluation. To improve the writing efficiency and diagnostic accuracy of breast MRI reports and promote standardized diagnosis and treatment of breast cancer, there is an urgent need for standardized imaging structured reports. We present the imaging structured report protocol of MRI for breast diseases utilized at West China Hospital of Sichuan university, which aims to promote standardized documentation of breast MRI reports.
In this study, we propose an automatic contour outlining method to measure the spatial resolution of homemade automatic tube current modulation (ATCM) phantom by outlining the edge contour of the phantom image, selecting the region of interest (ROI), and measuring the spatial resolution characteristics of computer tomography (CT) phantom image. Specifically, the method obtains a binarized image of the phantom outlined by an automated fast region convolutional neural network (AFRCNN) model, measures the edge spread function (ESF) of the CT phantom with different tube currents and layer thicknesses, and differentiates the ESF to obtain the line spread function (LSF). Finally, the values passing through the zeros are normalized by the Fourier transform to obtain the CT spatial resolution index (RI) for the automatic measurement of the modulation transfer function (MTF). In this study, this algorithm is compared with the algorithm that uses polymethylmethacrylate (PMMA) to measure the MTF of the phantom edges to verify the feasibility of this method, and the results show that the AFRCNN model not only improves the efficiency and accuracy of the phantom contour outlining, but also is able to obtain a more accurate spatial resolution value through automated segmentation. In summary, the algorithm proposed in this study is accurate in spatial resolution measurement of phantom images and has the potential to be widely used in real clinical CT images.
Objective To systematically review the prevalence of osteoporosis (OP) in Chinese postmenopausal females. Methods The CNKI, VIP, CBM, WanFang Data, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect studies on the prevalence of OP in Chinese postmenopausal females from inception to March 17th, 2022. Two reviewers independently screened the literature, extracted data and evaluated the risk of bias of the included studies. Meta-analysis was then performed using Stata 14.0 software. Results A total of 54 studies involving 96 391 cases and 41 651 confirmed OP patients were included. The meta-analysis results showed that the prevalence of OP in Chinese postmenopausal females was 38.8% (95%CI 34.1% to 43.5%). Subgroup analysis showed that the prevalence of OP was 31.7% (95%CI 16.6% to 48.6%) in females who had been menopausal for less than 5 years, 47.4% (95%CI 32.2% to 62.5%) for 5-9 years, 52.7% (95%CI 37.1% to 68.3%) for 10-14 years, 77.5% (95%CI 69.5% to 85.4%) for 15-19 years, and 78.3% (95%CI 56.3% to 100.0%) for more than 20 years. The rate was 16.2% (95%CI 28.8% to 37.2%) in under 50 years age group, 28.8% (95%CI 34.4% to 47.9%) for 50- years group, 41.1% (95%CI 34.4% to 47.9%) for 60- years group, 55.3% (95%CI 45.8% to 64.8%) for 70- years group, 82.0% (95%CI 76.1% to 87.9%) for 80- years group. The prevalence in different regions was between 31.0% and 43.5%, which was lowest in the northeast (31.0%, 95%CI 26.3% to 51.4%) and highest in the northwest (43.5%, 95%CI 22.3% to 64.7%). According to the year of publication, the rate was 43.9% (95%CI 15.7% to 72.0%) from 1997 to 2009 and 38.2% (95%CI 33.8% to 42.5%) from 2010 to 2021. The prevalence of OP was 24.9% (95%CI 20.5% to 29.3%) in postmenopausal females with no birth or 1 birth, and 45.0% (95%CI 37.0% to 53.0%) in females with 2 or more births. Conclusion The prevalence of OP in Chinese postmenopausal females is relatively high. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective
To investigate the value of ice test in the diagnosis of ptosis of myasthenia
gravis(MG).
Methods
A total of 32 patients with myasthenic ptosis and 33 with nonmyasthenic ptosis
underwent ice and rest test which were performed alternately twice within 1 day
on each patient. Besides, neostigmine test was performed on the patients with
myasthenic ptosis after ice and rest test . Two observers who didnrsquo;t know the
clinical diagnosis were asked to evaluate the improvement of eyelid elevation by measuring the width between the midpoints of upper and lower eyelid with a
20mm steel rule (precision of 0.5 mm). The average of margin of palpebral fissure width after double ice or rest tests subtrac ted from the one before the tests in one patient was the standard of the improve ment of eyelid elevation.
Results
Ice and rest test improved myasthenic ptosis but not nonmyasthenic ptosis with
the specificity of 100% in both of the tests. In addition, ice test improved
myasthenic ptosis more effectively with a higher sensitivity of 78%, and it could
also improve the palpebral fissure width in pa i tents with complete myasthenic
ptosis apparently. Compared with the neostigmine test, ice test had lower
sensitivity, cost shorter time, didnt need injection which avoided the discomfort,
and had no side effects.
Conclusion
Ice test is a simple and safe means with high sensitivity and specificity to
diagnose myasthenic ptosis, which is valuable in clinical application.
