Background

The purpose of the study was to evaluate the association between fetal echocardiographic measurements and the need for intervention (primary coarctation repair, staged coarctation repair, or catheter intervention) in prenatally diagnosed coarctation of the aorta.

Methods

A single-centre retrospective cohort study (2005-2015) of 107 fetuses diagnosed with suspected coarctation of the aorta in the setting of an apex-forming left ventricle and antegrade flow across the mitral and aortic valves.

Results

Median gestational age at diagnosis was 32 weeks (interquartile range, 23-35 weeks). Fifty-six (52%) did not require any neonatal intervention, 51 patients (48%) underwent a biventricular repair. In univariable analysis, an increase in ascending aorta (AAo) peak Doppler flow velocity (odds ratio [OR], 1.40 [95% confidence interval [CI], 1.05-1.91] per 20 cm/s; P = 0.03) was associated with intervention. No intervention was associated with larger isthmus size (OR, 0.23; P < 0.001), transverse arch diameter (OR, 0.23; P < 0.001), and aortic (OR, 0.72; P = 0.02), mitral (OR, 0.58; P = 0.001), and AAo (OR, 0.53; P < 0.001) z-scores. In multivariable analysis, higher peak AAo Doppler (OR, 2.51 [95% CI, 1.54-4.58] per 20 cm/s; P = 0.001) and younger gestational age at diagnosis (OR, 0.81 [95% CI, 0.70-0.93] per week; P = 0.005) were associated with intervention, whereas a higher AAo z-score (OR, 0.65 [95% CI, 0.43-0.94] per z; P = 0.029) and transverse arch dimension (OR, 0.44 [95% CI, 0.18-0.97]; P = 0.05) decreased the risk of intervention.

Conclusions

In prenatally suspected coarctation, the variables associated with intervention comprised smaller AAo and transverse arch size, earlier gestational age at diagnosis, and the additional finding of a higher peak AAo Doppler.  相似文献

Purpose

Motor skill screening tools are essential for the early detection of developmental coordination disorder (DCD). The present study aimed to examine any cultural and rater effects on these tools. This then enabled us to judge the validity of the original cut-off values for identifying diagnosable children.

Methods

A community sample survey was performed in Japan; 3852 children aged 6–9?years were recruited. Both parents and teachers evaluated the motor skills of their children using the Movement Assessment Battery for Children – Second Edition Checklist. The psychometric properties were evaluated and the scoring characteristics examined based on the type of rater and country of origin, as compared to data originally sampled in the UK.

Results

High reliability and validity of the Japanese samples were confirmed. The Japanese adults evaluated their children’s motor skills more rigorously than the Europeans. Additionally, there was a large disagreement between parent and teacher rating scores; the degree of agreement varied depending on the severity of motor deficits in the child.

Conclusion

The first findings from a Japanese sample suggest that the assessment of motor skills in children is significantly affected by culture and rater. These cultural characteristics and rater biases strongly suggest that new cut-off values, reflecting country and rater type, be introduced for identifying children at risk of DCD.  相似文献

Background and purpose

The vein of Galen aneurysmal malformation (VGAM) is a rare congenital vascular malformation with a higher morbidity and mortality, especially in neonates. Ultrasound, CT and MR are usually used in diagnosis and treatment monitoring of these disorders. In this current study, we aim to examine utility of SWI in evaluation of treatment response in infants with VGAM.

Materials and methods

We performed a retrospective chart analysis of children with VGAM in our institution between January 2008 and December 2016. Inclusion criteria included; confirmed VGAM on DSA; available SWI sequence at baseline and at follow up after at least a single embolization session; age at initial MR of 18?years or younger. Signal intensity and Angioarchitecture of VGAM and cerebral veins on SWI, as well as hydrocephalus and clinical outcome were evaluated.

Results

Of 11 patients identified with VGAM in our institution, 5 children (3 males and 2 females) satisfied the inclusion criteria. The average age at initial MR was 29?days (range 1–120). Fourteen MRI were available for review. All children had VGAM of mural type. Intramedullary veins were dilated and SWI-hypointense in all children, while subependymal and sulcal veins were dilated and SWI-hypointense in 4 patients on initial MRI. On the first available follow up MRI, cerebral veins have mostly normalized in 4 children and remained mostly dilated and SWI-hypointense in 1 child; even after complete treatment of the VGAM.

Conclusion

Our preliminary findings show that SWI seems to offer a beneficial non-invasive tool in evaluating passive venous congestion patterns in pediatric patients with VGAM. It remains to be determined in larger studies, the clinical significance of these SWI changes.  相似文献

Objective

To assess a 6-month nutritional and physical activity intervention program on the nutritional status of overweight or obese and not very active 8-14 years old children by means of a controlled pre-post design (ACTIVA’T program).

Method

Pre-post study in 8-14 years old overweight or obese and low active children from Vilafranca del Penedès (Barcelona, Spain) randomized in control group (n = 51, 47.1% girls, nutritional intervention and ≤3 h/wk physical activity) and ACTIVA’T group (n = 45, 37.8% girls, nutritional and physical activity ≥5 h/wk intervention). Body mass index, waist/height index, and diet quality by means of KIDMED test at the beginning and at the end of the program were assessed. During the intervention, each participant was accompanied by a relative (father or mother) who performed the same activities as the children.

Results

Dietary recommendations have positively changed the habits of both ACTIVA’T and control group. The reversion in the prevalence of overweight and obesity was 93.8% and 58.6%, respectively, in the ACTIVA’T group, compared to 25.0% and 35.8% in the control group. Abdominal obesity was decreased from 42.2% to 17.8% in the ACTIVA’T group and from 47.1% to 27.5% in the control group.

Conclusions

The program ACTIVA’T (nutritional education and physical activity promotion) improves the quality of diet and reverses the prevalence of overweight and obesity in the underactive child population.  相似文献

Background

Children have a statutory right to a smoke-free environment, and tobacco control advocates are now considering regulation of smoking behavior in the private sphere. The Norwegian Institute of Public Health has investigated the support for a ban on smoking in cars with children compared to other possible extensions of the tobacco act among the Norwegian public.

Material and methods

A nationwide representative survey (CAWI) of 5543 participants was conducted in 2014–2015. Respondents were asked to consider several possible new tobacco control measures, through selfreported ranking on 5-point scales for each measure. Multiple logistic regression models were applied to control for confounders (i.a. smoking behavior) for the tendency to state full support.

Results

A majority (78 % of all respondents, 61.8% of daily smokers) supported a proposal prohibiting smoking in cars when children are present. This proposal received substantially more support than bans on private balconies, in parks and at public transport stops and work entrances. Full support for the latter proposals varied between 39.9% and 58.1% (between 2.7% and 16.8% among smokers). Differences by smoking status were maintained after multiple controls.

Interpretation

The strong endorsement of the proposal (also provided by the majority of current smokers) suggests high legitimacy and compliance, which means that an implementation could be introduced without serious enforcement problems.  相似文献

目的分析学龄儿童单纯性肥胖症的MRI表现及MRS特点,确定其肝脏脂肪的MRI定量评估方法。方法将2015年1月—2016年12月期间临床诊断单纯性肥胖症的学龄儿童52例(男31例,女21例)作为病例组,平均年龄(10.1±1.1)岁。同年龄组[平均年龄(9.8±0.9)岁]的正常健康儿童40例(男22例,女18例)作为对照组。采用SIEMENS 1.5 T Avanto MR设备行MRI和~1H-MRS检查。观察肝实质于同相位、反相位影像上的信号变化;通过~1H-MRS获得肝脏兴趣区的水峰峰值(P_w)、水峰下面积(A_w)、脂峰峰值(P_l)及脂峰下面积(A_l)并计算出脂肪分数(FF)。采用独立样本t检验比较正常儿童和肥胖症患儿间P_w、A_w、P_l、A_l、FF差异;采用单因素方差分析比较轻、中、重度肥胖症患儿间各项指标的差异。并利用受试者操作特征(ROC)曲线评估MRS诊断脂肪肝的敏感度、特异度及准确度。结果肥胖症患儿组于T_1WI反相位影像上信号不同程度减低,而正常组T_1WI同反相位影像信号一致。MRS结果如下:(1)正常组和肥胖症组的P_w、A_w差异无统计学意义(P0.05)。(2)肥胖症患儿P_l、A_l、FF明显高于正常组(均P0.05);其中FF的诊断效能最高,敏感度为100%,特异度为82%,准确度为85%。(3)随着肥胖分级的增加,肥胖患儿的P_l、A_l均增高。结论 T_1WI双回波同反相位技术和MRS是目前定量测量肝脏脂肪含量的有效方法,在前者对脂肪肝做出初步诊断的基础上, MRS可进一步对脂肪肝进行量化分级。  相似文献
