Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

ObjectiveTo systematically review the intervention effect of cognitively engaging physical activity (CEPA) on executive function of children and adolescents. MethodsLiteratures in Chinese and English were retrieved from databases of Web of Science, PubMed, Medline, EBSCO and CNKI, from the establishment to November 30th, 2023. According to the inclusion and exclusion criteria, the literatures that met the requirements were screened, and their quality was evaluated and systematically reviewed. ResultsA total of 15 literatures were included, published between 2014 and 2023, from eight countries, involving 1 806 subjects aged four to 16 years. The average score of PEDro scale was 6.6. The intensity of the CEPA intervention ranged from 64% to 93% HR_max, the duration of a single session ranged from ten to 60 minutes, and the frequency of the intervention was two to five sessions a week, for four to 24 weeks. Specific forms of CEPA included football, basketball and floorball combined with cognitive tasks; running, jumping, squatting, sitting, spinning and balancing combined with cognitive tasks; and exergaming combined with cognitive tasks. Eleven researches showed positive effects of CEPA intervention on at least one component of executive function. However, six of the seven researches involving working memory failed to verify the positive effects. Twelve researches compared the intervention effects of CEPA and rutine exercise or regular physical education classes, and nine researches found that CEPA was more effective on executive function. ConclusionThe CEPA is effective on the executive function of children and adolescents, specifically on cognitive flexibility; it shows inconsistent effects on inhibitory control, and its effect on working memory has not been verified. The intervention types of CEPA are divided into ball games combined with cognitive tasks, basic motor skills training combined with cognitive tasks, and exergaming combined with cognitive tasks.

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.

The association among plasma trimethylamine-N-oxide (TMAO), FMO3 polymorphisms, and chronic heart failure (CHF) remains to be elucidated. TMAO is a microbiota-dependent metabolite from dietary choline and carnitine. A prospective study was performed including 955 consecutively diagnosed CHF patients with reduced ejection fraction, with the longest follow-up of 7 years. The concentrations of plasma TMAO and its precursors, namely, choline and carnitine, were determined by liquid chromatography-mass spectrometry, and the FMO3 E158K polymorphisms (rs2266782) were genotyped. The top tertile of plasma TMAO was associated with a significant increment in hazard ratio (HR) for the composite outcome of cardiovascular death or heart transplantation (HR = 1.47, 95% CI = 1.13-1.91, P = 0.004) compared with the lowest tertile. After adjustments of the potential confounders, higher TMAO could still be used to predict the risk of the primary endpoint (adjusted HR = 1.33, 95% CI = 1.01-1.74, P = 0.039). This result was also obtained after further adjustment for carnitine (adjusted HR = 1.33, 95% CI = 1.01-1.74, P = 0.039). The FMO3 rs2266782 polymorphism was associated with the plasma TMAO concentrations in our cohort, and lower TMAO levels were found in the AA-genotype. Thus, higher plasma TMAO levels indicated increased risk of the composite outcome of cardiovascular death or heart transplantation independent of potential confounders, and the FMO3 AA-genotype in rs2266782 was related to lower plasma TMAO levels.

Objective:To explore the clinical efficacy of disease-modifying drug nusinersen on children with spinal muscular atrophy.Methods:The baseline and longitudinal clinical data of 15 children who were treated with nusinersen in the Children′s Hospital, Zhejiang University School of Medicine from October 2019 to October 2021 were retrospectively collected. The general data (gender, age, genotype, and clinical classification, etc.), motor function, nutritional status, scoliosis and respiratory function were analyzed. Wilcoxon rank-sum test was used for comparing multi-system conditions before and after treatment.Results:The age of 15 cases (7 males, 8 females) was 6.8 (2.8, 8.3) years, with 2 cases of type 1, 6 cases of type 2, and 7 cases of type 3 respectively, and the course of disease was 55.0 (21.0, 69.0) months. After 9.0 (9.0, 24.0) months of treatment, the motor function scale evaluations of the Hammersmith neurological examination section 2 (13.0 (7.0, 23.0) vs. 18.0 (10.0, 25.0) scores, Z=-2.67, P=0.018) of 15 children, the Hammersmith functional motor scale expanded (38.0 (18.5, 45.5) vs. 42.0 (23.0, 51.0) scores, Z=-2.38, P=0.018), and the revised upper limb module (27.0 (19.5, 32.0) vs. 33.0 (22.5, 35.5) scores, Z=-2.52, P=0.012) of children with type 2 and 3 had significantly improved. Thirteen patients achieved clinically significant motor function improvement, and 2 of them had kept stable scale scores. Subjective reports also indicated that the muscle strength and daily exercise ability of these children improved after treatment, and no serious adverse reactions were reported. Supplemented by the multi-disciplinary team management, the levels of some indicators such as Cobbs angle of scoliosis and forced vital capacity all had significantly improved (all P<0.05). Conclusions:Nusinersen can improve the motor function of patients with 5q spinal muscular atrophy, which is also proved safe to be used in children. The drug treatment supplemented by the multi-disciplinary team management is helpful to improve the multi-system function of the children with spinal muscular atrophy.

Retinopathy of prematurity (ROP) is a proliferative vascular retinal disease. Cryotherapy, laser photocoagulation, intravitreal injection of anti-vascular endothelial growth factor, scleral buckling surgery and vitrectomy are the main treatments. Treated with cryotherapy or laser photocoagulation or intravitreal injection of anti-vascular endothelial growth factor, patients with a history of ROP have thicker foveas, and the morphology of the fovea and the development of the retinal vessels in the macular area are affected, resulting in abnormal vision development. However, the specific mechanisms by which different treatments of ROP affecting the development of the macula are not yet clear. It still need further study with large samples to verify and explore, whether changes in the levels of intraocular vascular endothelial growth factor changing the process of normal macular development and how the abnormal development of the macula affects visual function.

Objective:To explore the mediating effect of self-efficacy of family caregivers of dementia patients between patient-related impairment and caregivers' health-related quality of life.Methods:This study was a aross-sectional study. Using the convenient sampling method, family caregivers of dementia patients who accompanied patients in two ClassⅢ Grade A hospitals in Shanghai from December 2015 to September 2019 were selected as the research objects. Self-Efficacy Questionnaire for Chinese Family Caregivers (SEQCFC) , the MOS 36-item Short Form Health Survey (SF-36) and the Chinese Version of the Relevant Outcome Scale for Alzheimer's disease (CROSA) were used to conduct the questionnaire survey. SPSS 22.0 and AMOS 22.0 software were used for statistical analysis, Pearson correlation was used to calculate the correlation between variables and structural equation model was established to test the relationship between variables.Results:A total of 291 caregivers who met the inclusion criteria completed the questionnaire assessment, and the completion rate of the questionnaire was 100%. The impairment score of dementia patients was (87.13±23.88) , the total score of self-efficacy of care givers was (57.49±16.42) , the overall physical health score of health-related quality of life was (41.33±9.71) and the total score of mental health was (48.85±7.69) . The results of Pearson correlation analysis showed that in addition to the self-efficacy of the support dimension, the total score of the patients' dementia-related impairment was positively correlated with the total score of the caregivers' self-efficacy and the self-efficacy of the care giving behavior dimensions ( P< 0.05) . The total score of dementia-related impairment of patients was positively correlated with the total score of physical health and the total score of mental health of caregivers ( P<0.01) . The total score of caregivers' self-efficacy and the self-efficacy of each dimension of caregiving behavior were positively correlated with the total score of physical health and mental health of caregiver ( P<0.01) . Caregivers' self-efficacy was a partial mediator between dementia-related impairment and physical and mental health related quality of life of caregivers, and the mediation effect accounted for 29.79% and 43.67% of the total effect, respectively. Conclusions:The dementia-related damage of patients can directly affect the caregivers' health-related quality of life and it can also indirectly affect the caregivers' health-related quality of life through the caregivers' sense of self-efficacy. Therefore, it can reduce effects of dementia-related impairment on health-related quality of life of caregivers by improving caregivers' sense of self-efficacy.

Objective:The current systematic review aims to evaluate the effectiveness and quality of interventions on depressive symptoms of informal caregivers of people with dementia in China and to provide evidences regarding protocols for the most effective interventions.Methods:A systematic literature search of Chinese and English databases was performed, covering randomized controlled trails published up to March 2019. The papers for final review were selected based on the inclusion and exclusion criteria. Data were extracted and analyzed with RevMan 5.3, after a quality appraisal of the included studies.Results:A total of 17 papers were identified as eligible for descriptive analysis and 14 of the papers provided estimates for meta-analysis, with 991 participants. An overall mean reduction in depression was identified among the participants of intervention group, compared to those in the control group ( SMD value was -0.75, 95% CI -0.88 - -0.62, P<0.01). Psychotherapeutic ( SMD value was -0.59, 95% CI -0.78 - -0.40, P<0.01) and psychoeducational interventions ( SMD value was -0.84, 95% CI -1.02 - -0.67, P<0.01) showed significant reductions of depressive symptoms among the caregivers. In addition, Evidence exists for the effectiveness across from the short-term ( SMD value was -0.54, 95% CI -0.82 - -0.26, P<0.01), medium-term ( SMD value was -0.68, 95% CI -0.83 - -0.52, P<0.01) to the long-term interventions ( SMD value was -0.80, 95% CI -1.08 - -0.53, P<0.01). Conclusion:Interventions targeting to reduce depressive symptoms are effective among informal caregivers of persons with dementia in China. However, insufficient evidences are found regarding the most effective protocols and more high-quality studies are needed for the target population.

Objective To establish an animal model of annulus fibrosus (AF) partial defect for the repairing of interver?tebral disc (IVD) defect. Methods Image J 1.46r software was used to measure the T12/L1-L6/S1 intervertebral height in ovine lumbar spine X-ray films. AF thickness was measured by axial split disc. A 11 blade was used to make a trapezoid de?fect of upper bottom 3 mm, lower bottom 5 mm, height 5 mm and thickness 3 mm, whose lower bottom toward the nucleus pulposus (NP) in the left front of ovine lumbar IVD in vitro. The minimally invasive lateral approach was used to make the same type of trapezoid defect in the left front of the ovine lumbar IVD in vivo. The trapezoidal defect length of the axial divid?ing disc was measured, AF and a small amount of NP from trapezoidal defect in IVD were weighed, and the production of trapezoidal defect in IVD was evaluated. Results The lumbar intervertebral space height of ovine was (4.45 ± 0.28) mm. There were significant differences in the thickness of AF (4.08±0.50) mm , thickness (3 mm) and height (5 mm) of trapezoidal defect (P<0.05), respectively. There were no significant differences in trapezoidal defects in ovine lumbar IVD in vitro on the upper bottom (3.03 ± 0.09)mm, the lower bottom (5.03 ± 0.09) mm, the height (4.97 ± 0.10) mm, the thickness(3.02 ± 0.06) mm and the trapezoidal defect predetermined value on the upper bottom 3 mm, the lower bottom 5 mm, the height 5 mm and the thickness 3 mm (P>0. 05). The weights of the AF and NP taken out from ovine lumbar IVD in vitro and in vivo were (0.162 ± 0.011) g and (0.166 ± 0.014) g, and there was no significant difference between them (P > 0.05). Conclusion Through the operation of minimally invasive lateral approach, the method of making a trapezoidal defect in the experiments can establish animal model of AF partial defect, which meets the requirements for the repairing of IVD defect, and is simple, safe and reliable.
