Purpose: The prevalence of psychological distress is frequently observed among old adults with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, current researches are insufficient to clarify the correlation among these relevant factors. This study examined the effects of symptom burden, psychological resilience, coping styles, and social support on psychological distress. Methods: Two hundred fifty five elderly patients with AECOPD were conveniently selected in Taian, Shandong Province. The General Information Questionnaire, Distress Thermometer, The Revised Memorial Symptom Assessment Scale, Connor-Davidson Resilience Scale, Simplified Coping Style Questionnaire, Perceived Social Support Scale were used to investigate. The relationship among factors was estimated by using a structural equation model. Results: Psychological distress score of elderly patients with AECOPD was (5.25 ± 1.01); coping styles, psychological resilience, symptom burden, and social support directly affected psychological distress (thedirect effects were À.93, .17, .17, and À.09); coping styles had the largest total effect on psychological distress (the total effect was À.93); psychological resilience indirectly affected psychological distress through coping styles (the indirect effect was À.74); symptom burden indirectly affected psychologicaldistress through psychological resilience (the indirect effect was .25); social support indirectly affected psychological distress through symptom burden, psychological resilience, and coping styles (the indirecteffect was À.80). Conclusion The psychological distress of elderly patients with AECOPD is at a moderate level; coping styles, psychological resilience, and social support have positive effects on alleviating the psychological distress of elderly patients with AECOPD; symptom burden is negatively correlated with psychological distress.Healthcare professionals should pay more attention to elderly patients with AECOPD who are particularly prone to experience higher levels of psychological distress, especially in the presence of low coping style, limited psychological resilience, inadequate levels of social support, and high symptom burden.

Objective:To analyze the risk factors for central lymph node metastasis (CLNM) in patients with papillary thyroid cancer (PTC) aged 55 years and above, and to construct a predictive model with columnar graph.Methods:This retrospective study included 406 PTC patients aged 55 and above, treated at the First Affiliated Hospital of Zhengzhou University from Nov. 2019 to Feb. 2022. Data on demographic characteristics, disease features, and laboratory test results were collected. Univariate and multivariate logistic regression analyses were used to identify risk factors for CLNM and develop a clinical prediction model and nomogram.Results:The study involved 406 patients, divided into a modeling group (285 patients) and a validation group (121 patients). The predictive model identified independent risk factors for CLNM. In the modeling group, the model demonstrated a ROC AUC of 0.769, with 82.6% sensitivity, 63.0% specificity, and 67.7% accuracy. The validation group showed 66.7% sensitivity, 74.5% specificity, and 72.7% accuracy, with an AUC of 0.760. Hosmer-Lemeshow tests indicated good fit in both groups. Decision curve analysis confirmed the model's clinical decision-making value, showing better performance than traditional strategies and good generalizability and reliability.Conclusions:Sex, maximum tumor diameter, bilateral involvement of thyroid lobes, clinically evident cervical lymph nodes, and local invasion are independent predictive factors for CLNM in patients over 55 with papillary thyroid carcinoma (PTC). A clinical risk stratification nomogram model based on these risk factors demonstrates good predictive performance.

Objective To analyze the clinical characteristics of C-TI-RADS 3 thyroid nodules with a diameter greater than 2 cm and explore their correlation with gender,nodule ingredient,contralateral cancer presence,diffuse echo changes,TPOAB and TGAB.Methods A retrospective analysis was made on the clinical and pathological information of 94 patients with thyroid nodules who were admitted to our department from September 2022 to March 2023.All the patients underwent cytological and/or histopathological examinations.The proportions of TBS I category,benign tumors,low-risk tumors,and malignant tumors were calculated.The proportion of TBS type Ⅰ,benign tumors,low-risk tumors,and malignant tumors was quantified.Subsequently,a comparative analysis was conducted among the benign,low-risk,and malignant groups in terms of clinical characteristics including gender distribution,nodule composition,contralateral cancer occurrence,diffuse echo changes presence,as well as TPOAB and TGAB levels.Results Seven cases in TBS I category were excluded.Among the remaining 87 cases with confirmed pathology results for nodules,there were 72 benign cases(38 cytology cases and 34 histology cases),5 low-risk thyroid tumors(2 cytology cases and 3 histology cases),10 malignant cases(8 PTC cases,1 FTC case,and 1 MTC case).There was a significant difference in nodule ingredient(cystic/solid)between different pathological types(x2=10.369,P=0.006).However,no statistical significance was found in terms of gender,diffuse echo changes,contralateral cancer presence,TPOAB or TGAB(P＞0.05).Further analysis showed that the proportion of solid component was higher in low-risk tumors than in benign nodules(x2=9.571,P=0.002).No statistical significance was found between malignant nodules and low-risk nodules(x2=2.143,P=0.143),or between malignant nodules and benign nodules(x2=2.165,P=0.141).Conclusion Although TI-RADS 3 nodules are generally considered as potentially benign according to various versions of thyroid imaging reporting and data system,malignant nodules still account for a certain proportion.Attention should be paid to thyroid nodules with a typical ultrasonic signs,such as cystic nodules,thyroid follicular tumors and medullary thyroid carcinoma.Ultrasound guided fine needle aspiration cytopathology is necessary for evaluating benign and malignant nodules.It is necessary to pay attention to unsatisfactory or undiagnosable specimens to improve the accuracy of diagnosis.

Objective To analyze three-dimensional imaging characteristics and advantages for severe portal vein stenosis after liver transplantation, and to evaluate clinical efficacy of portal vein stent implantation. Methods Clinical data of 10 patients who received portal vein stent implantation for severe portal vein stenosis after liver transplantation were retrospectively analyzed. Imaging characteristics of severe portal vein stenosis, and advantages of three-dimensional reconstruction imaging and interventional treatment efficacy for severe portal vein stenosis were analyzed. Results Among 10 patients, 3 cases were diagnosed with centripetal stenosis, tortuosity angulation-induced stenosis in 2 cases, compression-induced stenosis in 2 cases, long-segment stenosis and/or vascular occlusion in 3 cases. Three-dimensional reconstruction images possessed advantages in accurate identification of stenosis, identification of stenosis types and measurement of stenosis length. All patients were successfully implanted with portal vein stents. After stent implantation, the diameter of the minimum diameter of portal vein was increased [(6.2±0.9) mm vs. (2.6±1.7) mm, P<0.05], the flow velocity at anastomotic site was decreased [(57±19) cm/s vs. (128±27) cm/s, P<0.05], and the flow velocity at the portal vein adjacent to the liver was increased [(41±6) cm/s vs. (18±6) cm/s, P<0.05]. One patient suffered from intrahepatic hematoma caused by interventional puncture, which was mitigated after conservative observation and treatment. The remaining patients did not experience relevant complications. Conclusions Three-dimensional visualization technique may visually display the location, characteristics and severity of stenosis, which is beneficial for clinicians to make treatment decisions and assist interventional procedures. Timely implantation of portal vein stent may effectively reverse pathological process and improve portal vein blood flow.

Objective:This study aimed to explore the status of radiological Kashin-Beck disease (KBD) among school-aged children in Chamdo City, Tibet, through a 3-year monitoring survey, providing epidemiological evidence for prevention and control strategies.Methods:The target areas for this study were Luolong, Bianba, and Basu counties in Chamdo City, Tibet Autonomous Region, identified as having the most severe historical cases of KBD. Children aged 7-12 years attending school were enrolled as study subjects. Anteroposterior X-ray films of the right-hand were taken, and radiological diagnoses were made based on the "Diagnosis of Kashin-Beck Disease" criteria (WS/T 207-2010). Two experienced researchers independently reviewed the X-rays, and intra- and inter-group consistency were assessed using weighted Kappa values and percentage agreement. Cross-sectional surveys were conducted in 2017 and 2020 to describe the X-ray detection rates of KBD, and logistic regression analysis was employed to construct a predictive model of risk factors for radiological KBD cases.Results:In 2017, a total of 5,711 children aged 7-12 years in Chamdo City, Tibet, participated in the baseline cross-sectional survey (average age 9.2 years, 48.0% female), with 28 cases of radiological KBD. The age- and gender-standardized prevalence rate was 0.527%. In 2020, 6,771 participants (average age 9.3 years, 49.5% female) underwent a second cross-sectional survey, with 9 cases of radiological KBD and a standardized prevalence rate of 0.134%. Logistic regression analysis indicated that older age [ OR=2.439, 95% CI(1.299, 4.580), P=0.006] and female gender [ OR=8.157, 95% CI(1.016, 65.528), P=0.048] were independent risk factors for radiological KBD cases. Conversely, higher residential altitude, under the premise of Tibet's high altitude, was a protective factor [ OR=0.995, 95% CI(0.990, 0.999), P=0.032). Conclusion:The radiographically positive detection rate of KBD among school-aged children in Chamdo City, Tibet Autonomous Region, is at an extremely low level and showing a declining trend, reaching the historical standard in 2020. Considering the absence of positive signs in affected children, it suggests that local KBD has been effectively eliminated.

Operation time, intraoperative blood loss and fusion stage were recorded. Intraoperative O-arm scanning and postoperative CT scanning were performed to evaluate the accuracy of nail placement. The cervicothoracic scoliosis Cobb angle, compensatory scoliosis Cobb angle, local kyphosis Cobb angle, torticollis angle, T 1 tilt angle and clavicular angle were measured before operation, model design, 1 week after operation and at the last follow-up to evaluate the effect of surgical design, intraoperative orthosis and the correction loss at follow-up. The Society for Scoliosis Research-22 (SRS-22) questionnaire was used to evaluate the functional and treatment effect. At the last follow-up, the osteotomy fusion was evaluated by Eck criterion. Results:All patients successfully completed the operation, the operation time was 228.5±41.8 min, the intraoperative blood loss was 355.6±46.7 ml, and the number of fusion segments was 5.5±0.8. Follow-up duration was 35.5±13.2 months. A total of 140 pedicle screws were inserted, with an accuracy of 97.1% (136/140). The Cobb angle of cervicothoracic scoliosis was 53.9°±17.9° preoperatively, 11.3°±4.4° in the model design, 10.8°±2.6° one week postoperatively, and 14.5°±3.5° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 78.6%±6.7%. The Cobb angle of compensatory scoliosis was 33.1°±12.1° before surgery, 11.9°±2.4° for model design, 10.5°±3.4° for one week after surgery, and 14.1°±2.5° for the last follow-up, with statistically significant differences ( P<0.001). The postoperative correction rate was 65.2%±16.2%. The Cobb angle of local kyphosis was 27.8°±9.8° preoperatively, 10.1°±2.1° in the model design, 9.8°±1.9° one week postoperatively, and 12.7°±1.6° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 59.2%±18.9%. The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 78.6%±6.7%. The neck tilt angle was 20.6°±6.7° preoperatively, 6.2°±1.9° in the model design, 5.9°±2.1° one week postoperatively, and 7.1°±1.4° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 70.0%±11.1%. The T 1 inclination angle was 20.2°±5.8° preoperatively, 11.5°±3.1° in the model design, 10.2°±2.3° one week postoperatively, and 9.5°±3.0° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 53.2%±10.4%. There was no significant difference between preoperative design and actual measurement one week after surgery ( P>0.05). At the last follow-up, the scores of self-image (4.6±0.7), mental health (4.7±0.6) and treatment satisfaction (4.6±0.6)in SRS-22 scale were significantly improved compared with those before operation ( P<0.05). The symptoms of hemivertebra ipilateral C 8 nerve root injury occurred in 1 patient, who was treated conservatively with dehydration, hormones and nutraceutical drugs, and recovered to normal at 3 months follow-up. At the last follow-up, the appearance of the head, neck and shoulders of the patients was improved compared with that before surgery, the bone grafts have achieved osseous fusion in all patients. All fusion were grade I by Eck criterion. No complications such as serious neurological or vascular injury occurred during perioperative period. No pseudoarthrosis formation, internal fixation loosening or fracture occurred during follow-up.
