Objective:To explore the potential categories of return-to-work self-efficacy of postoperative patients with thyroid cancer and analyze the influencing factors, so as to provide theoretical basis for implementing precise interventions of occupational rehabilitation.Methods:This was a cross-sectional study. A convenient sampling method was used to select 257 postoperative patients with thyroid cancer in Zhujiang Hospital of Southern Medical University from May 2022 to July 2023. The General Information Questionnaire, Return-To-Work Self-Efficacy Questionnaire and Cancer Fatigue Scale were used for investigation. Latent profile analysis was used to explore the potential categories of return-to-work self-efficacy of postoperative patients with thyroid cancer. Logistic regression and decision tree were used to analyze the influencing factors of different potential categories.Results:Finally, 250 postoperative patients with thyroid cancer were included. There were 76 males and 174 females, aged (37.91 ± 8.04) years old. The return-to-work self-efficacy of postoperative patients with thyroid cancer was divided into 2 potential categories: low return-to-work self-efficacy group (72.0%, 180/250) and high return-to-work self-efficacy group (28.0%, 70/250). Logistic regression showed education, thyrotropin suppressive therapy, cancer-related fatigue and age were factors influencing the potential categories of return-to-work self-efficacy of postoperative patients with thyroid cancer ( OR values were 0.951 - 19.820, all P<0.05). Decision tree model showed education level and cancer-related fatigue were the most important factors ( χ2 = 31.40, 16.95, both P<0.05). Conclusions:There were two potential categories of return-to-work self-efficacy of postoperative patients with thyroid cancer. Most of them had low levels of return-to-work self-efficacy. Health care professionals should focus on patients who are less educated and having cancer-related fatigue, meanwhile, should not ignore patients who are substandard thyrotropin suppressive therapy, and older. Implement precise interventions of occupational rehabilitation to improve the return-to-work self-efficacy of postoperative patients with thyroid cancer so as to help them reintegrate into society.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To investigate the clinical efficacy and safety of ixazomib-containing regimens in the treatment of patients with multiple myeloma(MM).Methods:A retrospective analysis was performed on the clinical efficacy and adverse reactions of 32 MM patients treated with a combined regimen containing ixazomib in the Hematology Department of the First People's Hospital of Lianyungang from January 2020 to February 2022.Among the 32 patients,15 patients were relapsed and refractory multiple myeloma(R/RMM)(R/RMM group),17 patients who responded to bortezomib induction therapy but converted to ixazomib-containing regimen due to adverse events(AE)or other reasons(conversion treatment group).The treatment included IPD regimen(ixazomib+pomalidomide+dexamethasone),IRD regimen(ixazomib+lenalidomide+dexamethasone),ICD regimen(ixazomib+cyclophosphamide+dexamethasone),ID regimen(ixazomib+dexamethasone).Results:Of 15 R/RMM patients,overall response rate(ORR)was 53.3％(8/15),among them,1 achieved complete response(CR),2 achieved very good partial response(VGPR)and 5 achieved partial response(PR).The ORR of the IPD,IRD,ICD and ID regimen group were 100％(3/3),42.9％(3/7),33.3％(1/3),50％(1/2),respectively,there was no statistically significant difference in ORR between four groups(x2=3.375,P=0.452).The ORR of patients was 50％after first-line therapy,42.9％after second line therapy,60％after third line therapy or more,with no statistically significant difference among them(x2=2.164,P=0.730).In conversion treatment group,ORR was 88.2％(15/17),among them,6 patients achieved CR,5 patients achieved VGPR and 4 patients achieved PR.There was no statistically significant difference in ORR between the IPD(100％,3/3),IRD(100％,6/6),ICD(100％,3/3)and ID(60％,3/5)regimen groups(x2=3.737,P=0.184).The median progression-free survival(PFS)time of R/RMM patients was 9 months(95％CI:6.6-11.4 months),the median overall survival(OS)time was 18 months(95％CI:11.8-24.4 months).The median PFS time of conversion treatment group was 15 months(95％CI:7.3-22.7 months),the median OS time not reached.A total of 10 patients suffered grade 3-4 adverse event(AE).The common hematological toxicities were leukocytopenia,anemia,thrombocytopenia.The common non-hematological toxicities were gastrointestinal symptoms(diarrhea,nausea and vomit),peripheral neuropathy,fatigue and infections.Grade 1-2 peripheral neurotoxicity occurred in 7 patients.Conclusion:The ixazomib-based chemotherapy regimens are safe and effective in R/RMM therapy,particularly for conversion patients who are effective for bortezomib therapy.The AE was manageable and safe.

Objective To observe the correlations of two-dimensional speckle tracking imaging(2D-STI)parameters of healthy fetal heart and gestational age in middle and late pregnancy.Methods Fetal echocardiography was prospectively performed in 279 healthy singleton fetuses in middle and late pregnancy.The fetuses were divided into group A(20-23+6 weeks of pregnancy,n=49),B(24-27+6 weeks of pregnancy,n=112),C(28-31+6 weeks of pregnancy,n=63),D(32-35+6 weeks of pregnancy,n=30)and group E(≥36 weeks of pregnancy,n=25)according to gestational age.Fetal left ventricle(LV)ejection fraction,LV and right ventricle(RV)area change fraction,LV and RV global radial strain(GRS),LV and RV myocardium and endocardium global longitudinal strain(MyoGLS,EndoGLS),LV myocardium and endocardium global circumferential strain(MyoGCS,EndoGCS)were obtained with 2D-STI and compared among 5 groups,and the correlations with gestational age were analyzed.Results Significant differences of fetal LV EndoGLS was found among 5 groups(P=0.044).Fetal LV GRS and RV GRS were positively correlated with gestational age(r=0.165,0.122,both P＜0.05)in middle and late pregnancy,while the absolute value of LV EndoGLS was negatively correlated with gestational age(r=-0.133,P=0.026).Conclusion LV GRS and RV GRS were positively correlated with gestational age in healthy fetuses in middle and late pregnancy,while the absolute value of LV EndoGLS was negatively correlated with gestational age.

Objective:To evaluate the morphological characteristics of the fetal heart and the contractile function of the left and right ventricles in fetuses with pulmonary stenosis (PS) and pulmonary atresia (PA) using fetal heart quantitative analysis technology (fetal HQ), and to assess the impact of different degrees of right ventricular outflow tract obstruction (RVOTO) on the contractile function of the fetal left and right ventricles. To accumulate early data and explore parameters for constructing a predictive model and clinical decision-making tool for the progression of fetal PS and PA.Methods:A retrospective analysis was conducted on 42 cases of mild to moderate PS and 23 cases of severe PS or PA detected through fetal echocardiography in the Department of Ultrasound, Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University, from July 2020 to December 2021. A control group of 195 normal fetal cases matching gestational weeks was selected. The fetal HQ technique was employed to measure the global sphericity index (GSI), left ventricular ejection fraction (EF), left/right ventricular area change percentage (LVFAC, RVFAC), and left/right ventricular longitudinal strain (LVGLS, RVGLS). Additionally, 24-segment sphericity index (SI) and fractional shortening (FS) for both left and right ventricles were measured. Comparative analyses were performed between the case and control groups, as well as within the case group.Results:In comparison with the control group, the case group exhibited significantly decreased GSI, LVGLS, LVEF, LVFAC, RVGLS, and RVFAC.The differences were statistically significant in the mild to moderate PS group (all P<0.05) and highly significant in the severe PS/PA group (all P<0.01). In the mild to moderate PS group, the left ventricle′s 2nd segment, right ventricle′s 24th segment SI, and the left ventricle′s 1st-13th segments, right ventricle′s 1st-16th and 20th-24th segments FS showed statistically significant differences compared to the control group (all P<0.05). In the severe PS/PA group, the right ventricle′s 1st-22nd segment SI, and the left ventricle′s 6th-13th, 21st-24th segments, and the right ventricle′s 1st-14th segments FS were reduced, showing statistically significant differences compared to the control group (all P<0.05). The severe PS/PA group showed lower RVGLS, RVFAC, and SI for the right ventricle′s 1st to 17th segments when compared to the mild to moderate PS group, with statistically significant differences (all P<0.05). Conclusions:Quantitative indices derived by fetal HQ is capable of evaluating the cardiac morphology and function of fetuses with PS/PA, which may provide for reference information for comprehensive understanding of cardiac morphological and functional changes in such fetuses.

Objective To investigate the best evidence application of exercise prescription in patients with chronic heart failure in clinical practice and evaluate its effectiveness.Methods The best evidence of exercise prescription for patients with chronic heart failure was summarized,and the evidence-based practice plan was developed,and it was implemented in the cardiology department of a tertiary hospital in Zhejiang Province from August to October,2022.Nurses'exercise prescription knowledge-attitude-practice level,implementation rate of review indicators,the length of hospital stay,exercise endurance,daily living ability and grip strength of both groups before and after the intervention were compared.Results After the application of the best evidence,the score of knowledge dimension was(9.34±0.98)points;the score of attitude dimension was(63.29±1.37)points;the score of practice dimension was(25.49±1.51)points,which were statistically significant compared with the scores before the application of evidence(P<0.05).After the application of the best evidence,the implementation rate of 16 review indicators was higher than that before the application of evidence(P<0.001).The length of hospital stay in the evidence application group was shorter than that in the baseline examination group(Z=-2.610,P<0.001).After intervention,the exercise endurance,daily living ability and grip strength of patients in the evidence application group were improved compared with the baseline review group,and the difference was statistically significant(P<0.05).Conclusion After the application of the best evidence of exercise prescription in patients with chronic heart failure,it can improve the level of knowledge,attitude and practice of nurses on exercise prescription,standardize the compliance of nurses'exercise prescription,reduce the number of days in the hospital,and improve patients'exercise endurance,daily living ability and grip strength.

Objective:To analyze the correlation between left and right atrial diameters and fetal biological growth parameters of normal fetuses in middle and late trimester, and to establish normal reference and Z-score model for left and right atria.Methods:Three hundred and ninety-two fetuses in middle and late trimester were prospectively selected from July 2022 to October 2022 in Sir Run Run Shaw Hospital.Non-cardiac biometric parameters included biparietal diameter (BPD), femoral length (FL), and gestational age (GA) based on menstrual age were assessed.Left and right atrial widths (LAW, RAW) and atrial lengths (LAL, RAL) at end-systole, left and right atrial areas (LAA, RAA) at end-systole and the heart area (HA) at end-diastole were measured in standard apical four-chamber or basal four-chamber view. The ratio of RA and LA transverse diameters (RAW/LAW), the ratio of RA and LA length diameters (RAL/LAL), ratio of RA and LA area (RAA/LAA), spherical index of the ratio of RA and LA length to transverse diameter (RASI, LASI), ratio of LA and RA area to heart area (LAA/HA, RAA/HA) were calculated. The best regression equation was established using GA, BPD and FL as independent variables and LAL, LAW, LAA, RAL, RAW, RAA as dependent variable. The correlation between the standard deviation (SD) and the independent variables GA, BPD and FL was analyzed, and then the above statistics were used to calculate the corresponding Z-score for each variable of RA and LA using the regression equation.Results:①Significant positive correlations were found between LAW, RAW, LAL, RAL, LAA and RAA with the increase of GA, BPD and FL, and the highest degree of correlation between RAA, LAA and GA was denoted ( r=0.927, 0.920, all P<0.001). ②Taking GA as an example, there was no significant correlation between RAL/LAL, RAW/LAW and GA ( r=-0.064, 0.077; all P>0.05). RAA/LAA showed a very weak positive correlation with GA ( r=0.106, P=0.037), with normal reference values of 1.002±0.091, 1.091±0.093, 1.059±0.090, respectively. Interestingly RAL/LAL was found close to 1, while RAW/LAW and RAA/LAA were always >1. No significant correlations were found between LAA/HA, RAA/HA and GA ( r=0.003, 0.056; all P>0.05), with normal reference values of 0.155±0.026, 0.163±0.026, respectively, and RAA/HA was found larger than LAA/HA. LASI showed a very weak positive correlation with GA ( r=0.112, P=0.027), while there was no significant correlation between RASI and GA ( r=0.003, P>0.05), the normal reference values were 1.068±0.113, 0.980±0.105, respectively. ③The SD of LAL, LAW, etc.showed a simple linear relationship with the independent variables. Taking RAA and GA as examples, the linear regression equation for RAA was Y=-1.690+ 0.107 0GA ( r=0.927, P<0.001) and the linear regression equation for RAA-SD was Y=-0.107+ 0.010 4GA ( r=0.320, P<0.001). The Z-scores for LAL, LAW, LAA, RAL, RAW and RAA were relatively constant with the growth of GA, BPD and FL, with the corresponding Z-scores for GA were -1.817~3.631( r=0.000 3), -1.605~2.995( r<-0.000 1), -1.700~3.107( r<0.000 1), -1.617~3.466( r=0.000 1), -1.491~3.025( r<-0.000 1), -1.566~3.104( r=0.000 2), respectively. Conclusions:This study preliminarily establish the reference value ranges and Z-score of atrial diameters in normal fetuses during middle and late trimester, providing a reference basis for accurate quantitative evaluation of fetal atrial development and analysis of fetal congenital heart abnormalities, and contributing to the early detection of pathological conditions leading to abnormal atrial size.
