Objective To explore the prevalence and related risk factors of thyroid nodule in elderly patients(age ≥ 60 years old) with type 2 diabetes mellitus(T2DM)) in Xinjiang region.Methods Two hundreds and two elderly patients with T2DM were selected,including 91 cases of thyroid nodule(thyroid nodule group) and111 cases of non-thyroid nodule (control group).The disease history,body mass index(BMI),fasting blood-glucose (FBG),2-h postprandial blood glucose(2 h PBG),glycosylated hemoglobin(HbA1c),triglyceride(TG),cholesterol(TC),high-density lipoprotein(HDL-C) and low density lipoprotein(LDL-C) were collected for statistical analysis.Results The age,gender,BMI,TC and HbA1c had statistical difference between the two groups (P<0.05);the disease course,pulse pressure,systolic pressure,abdominal perimeter,smoking history,HDL,TG,FBG and 2 h PBG had no statistical differences netween the thyroid nodule group and non-thyroid nodule group (P>0.05).The multivariable Logistic regression analysis showed that the age,gender,TC,HbA1c and BMI were the risk factors of thyroid nodule occurrence.Conclusion Conducting the thyroid nodule related imaging examination has an important clinical significance for diabetic elderly women patients with obesity and cholesterol increase.

BACKGROUND:Ultrasonography as a noninvasive means has been widely recognized in the examination of the skeletal muscle system. OBJECTIVE: To investigate the clinical significance of ultrasonography for the elderly with degenerative knee cartilage. METHODS:Totaly 102 patients (204 knees) who were≥ 60 years old and successively admitted for knee disease were selected and according to clinical diagnostic criteria of degenerative knee disease, divided into two groups: osteoarthritis group (167 knees) and non-osteoarthritis group (37 knees). Al the knees were subjected to ultrasonography for observing the effusion depth of the suprapatelar bursa, medial bursa and lateral bursa, as wel as the synovium, pannus and cartilage. RESULTS AND CONCLUSION: Of the 204 knee joints, degenerative changes of the knee occurred in 167 knees, primary knee arthritis in 91 knees, secondary knee arthritis in 76 knees, and the degeneration rate was 82%. The volume of effusion in the suprapatelar bursa, medial bursa and lateral bursa was significantly higher in the osteoarthritis group than the non-osteoarthritis group. In the osteoarthritis group, synovial hyperplasia was in 59 knees, pannus formation in 23 knees, rough cartilage surface in 167 knees, and the knee cartilage thinning or loss in 117 knees. In the non-osteoarthritis group, synovial hyperplasia was in 5 knees, rough cartilage surface in 27 knees, and the knee cartilage thinning or loss in 4 knees. These findings indicate that ultrasonography is of certain clinical significance in evaluation of degenerative knee cartilage in the elderly.

Objective:To optimize the Manchester needs tool for injured children (MANTIC) scale , and evaluate its reliability and validity among injured children. Methods:The MANTIC scale was optimized through Delphi expert consultation and pre-tests. From March 2023 to June 2023 , a total of 317 injured children admitted in 7 level A tertiary hospitals in Zhejiang and Shandong provinces and their families were surveyed with general data, optimized MANTIC scale, and EuroQol 5-dimension health questionnaire for youth (EQ-5D-Y). Item analysis was conducted on the data of the 317 patients collected with optimized MANTIC scale through the test for homogeneity and value-based decision-making method and the content validity test of the scale was evaluated with item-level content validity index (I-CVI) and scale-level content validity index (S-CVI). It was evaluated with KMO test values and Bartlett′s test of sphericity to determine whether the scale was suitable for exploratory factors. The number of common factors was determined based on the K1 criterion and scree plot to further obtain the structural validity of the scale of the item load value. The correlation validity of the scale was evaluated with the correlation coefficient of the optimized MANTIC scale and EQ-5D-Y. The reliability of the scale was tested with Cronbach alpha coefficient and Guttman split-half reliability coefficient. Results:A total of 332 questionnaires were distributed, among which 317 valid ones were collected, with a response rate of 95.6%. The test of homogeneity in the item analysis showed that the correlation coefficient between each item and the total score of the scale was 0.40-0.80. The results of the value-based decision-making method showed that the critical ratio of high-and low-scored groups was 6.08-28.01. The quality of all the items met the retention requirements so that the reliability and validity tests could be continued. Validity test found that I-CVI was 0.83-1.00, consistent S-CVI was 0.83, and mean S-CVI was 0.95. In structural validity analysis, the KMO value was 0.96, and the Chi-square value of Bartlett′s test of sphericity was 10755.76 ( P<0.01). A total of 9 common factors were extracted with the K1 criterion (eigen value>1), and the scree plot indicated 9 common factors with a cumulative variance contribution rate of 73.46%. Factor extraction and rotation showed that the load value of each item of the scale ranged from 0.589 to 0.874. The correlation coefficient of the optimized MANTIC scale and EQ-5D-Y was r= 0.55 ( P<0.01).Reliability test showed that the Cronbach alpha coefficient of the total scale and all dimensions was 0.96 and 0.77-0.98, and the Guttman split-half reliability coefficient was 0.76 and 0.73-0.98. Conclusion:The optimized MANTIC scale can attain good reliability, validity, consistency and stability, and can reflect the concept to be expressed and the content to be evaluated, indicating that it can be used to evaluate the injury rehabilitation needs of injured children and their families throughout the entire treatment process.
