ABSTRACT
ObjectiveTo analyze the changing trend of cerebrovascular disease burden in Minhang District of Shanghai from 1996 to 2021， and to provide scientific evidence for government to formulate targeted cerebrovascular disease prevention and control strategies. MethodsMortality， years of life lost（YLL）， years of lived with disability（YLD） and disability⁃adjusted life years（DALY） were used to evaluate the burden of cerebrovascular diseases in Minhang District. Joinpoint linear regression was used to analyze the trend of disease burden. ResultsFrom 1996 to 2021， the YLL rate of cerebrovascular diseases in Minhang District showed a downward trend （whole population： APC=-1.69%， t=-6.9， P<0.05）， The YLD rate of cerebrovascular diseases showed a slow upward trend （whole population： APC=1.17%， t=3.5， P<0.05）， The DALY rate of cerebrovascular diseases showed a downward trend， and fluctuated since 2003 （whole population： APC= -1.43%， t=-5.6， P<0.05）. The YLL rate of cerebrovascular diseases in men was higher than that in women， and the YLD rate of cerebrovascular diseases in women was higher than that in men. After 2014， the DALY of cerebrovascular diseases in men was higher than that in women. With the increase of age， the burden of cerebrovascular diseases increased， and the burden of disease increased significantly in the age group above 70. ConclusionThe burden of cerebrovascular diseases in Minhang District is at a high level， and there are differences in age， gender and other aspects. Measures such as screening， intervention and rehabilitation need to be improved to reduce disability and premature death caused by cerebrovascular diseases and to reduce the burden of cerebrovascular diseases on individuals， families and society.
ABSTRACT
Objective@#To investigate the value of initial CT quantitative analysis of ground-glass opacity (GGO), consolidation, and total lesion volume and its relationship with clinical features for assessing the severity of coronavirus disease 2019 (COVID-19). @*Materials and Methods@#A total of 84 patients with COVID-19 were retrospectively reviewed from January 23, 2020 to February 19, 2020. Patients were divided into two groups: severe group (n = 23) and non-severe group (n = 61). Clinical symptoms, laboratory data, and CT findings on admission were analyzed. CT quantitative parameters, including GGO, consolidation, total lesion score, percentage GGO, and percentage consolidation (both relative to total lesion volume) were calculated. Relationships between the CT findings and laboratory data were estimated. Finally, a discrimination model was established to assess the severity of COVID-19. @*Results@#Patients in the severe group had higher baseline neutrophil percentage, increased high-sensitivity C-reactive protein (hs-CRP) and procalcitonin levels, and lower baseline lymphocyte count and lymphocyte percentage (p < 0.001). The severe group also had higher GGO score (p < 0.001), consolidation score (p < 0.001), total lesion score (p < 0.001), and percentage consolidation (p = 0.002), but had a lower percentage GGO (p = 0.008). These CT quantitative parameters were significantly correlated with laboratory inflammatory marker levels, including neutrophil percentage, lymphocyte count, lymphocyte percentage, hs-CRP level, and procalcitonin level (p < 0.05). The total lesion score demonstrated the best performance when the data cut-off was 8.2%. Furthermore, the area under the curve, sensitivity, and specificity were 93.8% (confidence interval [CI]: 86.8–100%), 91.3% (CI: 69.6–100%), and 91.8% (CI: 23.0–98.4%), respectively. @*Conclusion@#CT quantitative parameters showed strong correlations with laboratory inflammatory markers, suggesting that CT quantitative analysis might be an effective and important method for assessing the severity of COVID-19, and may provide additional guidance for planning clinical treatment strategies.
ABSTRACT
Objective@#To evaluate the differential diagnosis of idiopathic granulomatous mastitis (IGM) and invasive ductal carcinoma.@*Methods@#The ultrasonographic data of 37 IGM patients and 50 cases of IDC were analyzed retrospectively. The shape, growth direction, margin, internal echo, posterior echo, calcification, Adler blood flow classification, PSV(peak sestolic velocity), RI (resistance index)and elasticity scores were analyzed by χ2 test and independent sample t test. The optimal cutoff values of age, PSV and RI were calculated by receiver operating characteristic (ROC) curve. Logistic regression analysis was used to calculate the odds ratio (OR) of ultrasonic variates in the diagnosis of both diseases.@*Results@#There were no significant differences in the shape, margin, internal echo and blood flow grading between the two groups. The age, lesion growth direction, posterior echo, calcification, PSV, RI and elasticity were statistically different. The cut-of value of Age, PSV and RI were 38.5 years old, 13.20 cm/s, and 0.655. Logistic regression multi-variated analysis revealed that elastic score (OR=9.806) had the best value of the differential diagnosis, as well as calcification (OR=6.937), posterior echo decay (OR=4.613), RI (OR=3.257), lesion growth orientation (OR=3.198), and PSV (OR=1.202). Lesion shape, margin, internal echo, and Adler blood flow classification did not help in differential diagnosis.@*Conclusion@#Ultrasound multi-parameter analysis has high value in IGM and IDC differential diagnosis.
