Objective:To summarize the clinical characteristics of SAPHO syndrome in elderly patients with organizing pneumonia.Methods:We reported a case of SAPHO syndrome in an elderly patient with organizing pneumonia.Relevant reports on SAPHO syndrome with organizing pneumonia at home and abroad were retrieved, and the literature was summarized an analyzed.Results:The patient was a 63-year-od female who was admitted to the hospital due to "intermittent fever and cough for more than two months". Before admission, she was previously diagnosed with pneumonia in another hospital with poor response to anti-infective treatment.Chest CT showed multiple bilateral patchy consolidations in both lungs, with migratory changes and reversed halo signs.Her medical history included bone and joint pain(e.g., sternoclavicular joints)and palmoplantar pustulosis.Lung biopsy pathology confirmed organizing pneumonia. 99mTc-MDP bone scintigraphy revealed abnormal bone salt metabolism in multiple bone and joint areas.The final diagnosis was SAPHO syndrome with organizing pneumonia.Both symptoms and imaging significantly improved after prednisone treatment.Two related cases were retrieved from the literature.One was a 57-year-old female reported in the UK, who had been diagnosed with SAPHO syndrome before and was found to have lung consolidations due to respiratory symptoms.Lung biopsy confirmed organizing pneumonia, and she improved after glucocorticoid treatment.The other was a 59-year-old Chinese female who visited hospital due to pain in the lumbosacral part and left lower limb.After being diagnosed with SAPHO syndrome, a chest CT scan was performed and lung consolidations were found.The pathology confirmed organizing pneumonia.The patient improved after treatment with Tripterygium wilfordii. Conclusion:SAPHO syndrome complicated with organizing pneumonia is rare, with diverse clinical manifestations, and responds well to glucocorticoid therapy.

Objective:To explore the effect of different salt intake levels on clinical outcomes after the first embryo transfer in women undergoing assisted reproductive technology.Methods:This was a retrospective cohort study. A total of 163 patients with the first in vitro fertilization/intracytoplasmic sperm injection and embryo transfer from January 2021 to July 2021 in Reproductive Medical Center, Henan Provincial People's Hospital were recruited. The spot urine method was used to estimate the 24 h salt intake of patients, and all patients were divided into three groups based on their 25th and 75th percentiles: low-salt group (≤9.21 g, n=41), medium-salt group (9.22-13.31 g, n=81), and high-salt group (≥13.32 g, n=41). Baseline data and clinical outcomes were analyzed and compared among the three groups. Results:The rate of MII oocyte [72.7% (410/564)], and the rate of high-quality embryos [42.1% (109/259)] in the high-salt group were lower than those in the low-salt group [82.5% (461/559), P<0.05; 52.4% (154/294), P<0.05], the differences among the three groups were statistically significant ( P<0.001, P=0.048). The rate of normal cleavage [99.1% (568/573)] in the medium-salt group was higher than that in the low-salt group [96.1% (294/306), P<0.05], and the difference among the three groups was statistically significant ( P=0.003). After adjusting for potential confounding factors by using multivariate logistic regression, the clinical pregnancy rate ( OR=0.520, 95% CI: 0.221-1.221, P=0.133), the early miscarriage rate ( OR=1.226, 95% CI: 0.219-6.851, P=0.817), and the live birth rate ( OR=0.730, 95% CI: 0.323-1.647, P=0.448) in the medium-salt group, the clinical pregnancy rate ( OR=0.659, 95% CI: 0.246-1.762, P=0.406), the early miscarriage rate ( OR=1.080, 95% CI: 0.162-7.180, P=0.937), and the live birth rate ( OR=1.012, 95% CI: 0.396-2.588, P=0.980) in the high-salt group were comparable with the low-salt group (all P>0.05). Conclusion:High level of salt intake does not affect the clinical pregnancy outcomes of infertile women in their first transplantation cycle. However, it has an adverse effect on oocyte maturation, normal cleavage, and high-quality embryo formation.

Objective To assess the value of cardiac magnetic resonance(CMR)imaging for predicting adverse left ventricular remodeling in patients with ST-segment elevation myocardial infarction(STEMI).Methods We retrospectively analyzed the clinical data and serial CMR(cine and LGE sequences)images of 86 STEMI patients within 1 week and 5 months after percutaneous coronary intervention(PCI),including 25 patients with adverse LV remodeling and 61 without adverse LV remodeling,defined as an increase of left ventricular end-systolic volume(LVESV)over 15%at the second CMR compared to the initial CMR.The CMR images were analyzed for LV volume,infarct characteristics,and global and infarct zone myocardial function.The independent predictors of adverse LV remodeling following STEMI were analyzed using univariate and multivariate Logistic regression methods.Results The initial CMR showed no significant differences in LV volume or LV ejection fraction(LVEF)between the two groups,but the infarct mass and microvascular obstructive(MVO)mass were significantly greater in adverse LV remodeling group(P<0.05).Myocardial injury and cardiac function of the patients recovered over time in both groups.At the second CMR,the patients with adverse LV remodeling showed a significantly lower LVEF,a larger left ventricular end-systolic volume index(LVESVI)and a greater extent of infarct mass(P<0.001)with lower global peak strains and strain rates in the radial,circumferential,and longitudinal directions(P<0.05),infarct zone peak strains in the 3 directions,and infarct zone peak radial and circumferential strain rates(P<0.05).The independent predictors for adverse LV remodeling following STEMI included the extent of infarct mass(AUC=0.793,95%CI:0.693-0.873;cut-off value:30.67%),radial diastolic peak strain rate(AUC=0.645,95%CI:0.534-0.745;cut-off value:0.58%),and RAAS inhibitor(AUC= 0.699,95%CI:0.590-0.793).Conclusion The extent of infarct mass,peak radial diastolic strain rate,and RAAS inhibitor are independent predictors of adverse LV remodeling following STEMI.

Objective To investigate the application efficiency and potential of CT radiomics in differentiating malignant and benign sub-centimeter solid pulmonary nodules. Methods A retrospective study was performed on the sub-centimeter ( ≤ 10 mm) solid pulmonary nodules detected by enhanced CT in our hospital from March 2020 to January 2023. Malignancy was confirmed by surgical pathology, and benignity was confirmed by surgical pathology or follow-up. Lesions were manually segmented and radiomic features were extracted. The feature dimension was reduced via feature correlation analysis and least absolute shrinkage and selection operator (LASSO). The 5-fold cross validation was used to validate the model. Support vector machine, logistic regression, linear classification support vector machine, gradient boosting, and random forest models were established for CT radiomics. Receiver operating characteristic curves were drawn. Delong test was used to compare the diagnostic performance of the five classifiers. The optimal model was selected and compared to radiologists with medium and high seniority. Results A total of 303 nodules, 136 of which were malignant, were examined. Radiomics models were established after feature extraction and selection. On test set, the areas under the receiver operating characteristic curves of support vector machine, logistic regression, linear classification support vector machine, random forest, and gradient boosting models were 0.922 (95%CI: 0.893, 0.950), 0.910 (95%CI: 0.878, 0.942), 0.905 (95%CI: 0.872, 0.938), 0.899 (95%CI: 0.865, 0.933), and 0.896 (95%CI: 0.862, 0.930), respectively. Delong test indicated no significant differences in the performance of the five radiomics models, and the support vector machine model showed the highest accuracy and F1 score. The support vector machine model showed significantly higher diagnostic accuracy as compared to radiologists (83.8% vs. 55.4%, P < 0.001). Conclusion The radiomics models achieved high diagnostic efficiency and may help to reduce the uncertainty in diagnosis of malignant and benign sub-centimeter solid nodules by radiologists.

OBJECTIVE: To quantitatively assess cardiac functions in patients with cardiac amyloidosis (CA) and hypertrophic cardiomyopathy (HCM) using cardiac magnetic resonance-feature tracking (CMR-FT) technique and evaluate the prognostic value of CMR-FT in patients with CA. METHODS: We retrospectively collected the data from 31 CA patients with systemic amyloidosis confirmed by Congo red staining and serum immunohistochemistry after extracardiac tissue biopsy undergoing CMR at our hospital from March, 2013 to June, 2021.Thirty-one age and gender matched patients with asymmetric left ventricular wall hypertrophy and 31 healthy individuals without organic or functional heart disease served as the controls.Radial, circumferential and longitudinal strains and strain rates of the left ventricle at the global level and in each myocardial segment (basal, middle and apical) were obtained with CMR-FT technique and compared among the 3 groups.The predictive value of myocardial strains and strain rates for all-cause mortality in CA patients was analyzed using a stepwise COX regression model. RESULTS: The left ventricular volume, myocardial mass, ejection fraction and cardiac output differed significantly among the groups (P < 0.05).Except for apical longitudinal strain, the global and segmental strains were all significantly lower in CA group than in HCM group (P < 0.05).The global and segmental strains were all significantly lower in CA group than in the healthy individuals (P < 0.05).The basal strain rates in the 3 directions were significantly lower in CA group than in the healthy individuals (P < 0.05), but the difference in apical strain rates was not statistically significant between the two groups.Multivariate stepwise COX analysis showed that troponin T (HR=1.05, 95%CI: 1.01-1.10, P=0.017) and middle peak diastolic circumferential strain rate (HR=6.87, 95%CI: 1.52-31.06, P=0.012) were strong predictors of death in CA patients. CONCLUSION Strain and strain rate parameters derived from CMR-FT based on cine sequences are new noninvasive imaging markers for assessing cardiac impairment in CA and cardiac function changes in HCM, and provide independent predictive information for all-cause mortality in CA patients.
