Association of Breastfeeding Duration with Body Composition in Children Aged 3-5 Years / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to assess the relationship between the body composition of children aged 3-5 years and breastfeeding status and duration.@*METHODS@#The study was conducted using data from the National Nutrition and Health Systematic Survey for children 0-17 years of age in China (CNHSC), a nationwide cross-sectional study. Breastfeeding information and potential confounders were collected using standardized questionnaires administered through face-to-face interviews. The body composition of preschool children was measured using bioelectrical impedance analysis. A multivariate linear regression model was used to assess the relationship between breastfeeding duration and body composition after adjusting for potential confounders.@*RESULTS@#In total, 2,008 participants were included in the study. Of these, 89.2% were ever breastfed and the median duration of breastfeeding was 12 months (IQR 7-15 months). Among children aged 3 years, the height-for-age Z-score (HAZ) for the ever breastfed group was lower than that for never breastfed group (0.12 vs. 0.42, P = 0.043). In addition, the weight-for-age Z-score (WAZ) of the ever breastfed group was lower than that of the never breastfed group (0.31 vs. 0.65, P = 0.026), and the WAZ was lower in children aged 4 years who breastfed between 12 and 23 months than in those who never breastfed. Compared to the formula-fed children, the fat-free mass of breastfed infants was higher for children aged 3 years (12.84 kg vs. 12.52 kg, P = 0.015) and lower for those aged 4 years (14.31 kg vs. 14.64 kg, P = 0.048), but no difference was detected for children aged 5 years (16.40 kg vs. 16.42 kg, P = 0.910) after adjusting for potential confounders. No significant difference was detected in the weight-for-height Z-score (WHZ), body mass index (BMI)-for-age Z-score (BAZ), fat-free mass index, and body fat indicators in the ever breastfed and never breastfed groups and among various breastfeeding duration groups for children aged 3-5 years.@*CONCLUSION@#No obvious associations were detected between breastfeeding duration, BMI, and fat mass indicators. Future prospective studies should explore the relationship between breastfeeding status and fat-free mass.

Coverage and effectiveness of COVID-19 vaccines among people aged 60 years and above in Changning District of Shanghai / 上海预防医学

ObjectiveTo assess the coverage and effectiveness of COVID-19 vaccines in the elderly. MethodsThis study was conducted in Changning District of Shanghai， targeting people aged 60 years and above. Vaccination data between 21 December 2020 and 28 February 2022 was retrieved from the Shanghai Collective Immunization System. Information on confirmed cases of COVID-19 from March 2022 through May 2022 was collected from the National Notifiable Diseases Reporting System. Vaccine effectiveness was calculated using the screening method. ResultsAs of 28 February 2022， 69.89% of people aged ≥60 years had received ≥1-dose vaccine， 63.80% had received full primary vaccination and 31.91% had received a booster dose. Vaccination coverage declined over age， with the lowest coverage in the elderly aged ≥80 years. Moreover， COVID-19 vaccination provided the highest protection against severe/critical illness and death due to the Omicron variants in the elderly aged ≥60 years. Full primary vaccination showed 96.15%（95%CI：84.15‒99.06）of vaccine effectiveness and booster vaccination showed 100% of the effectiveness against severe/critical COVID-19 and death. ConclusionsFull primary and booster vaccination coverage in the elderly is low， especially in those aged 80 and above. Our study finds high protection against COVID-19 associated severe/critical illness and death from both full primary and booster vaccination of inactivated COVID-19 vaccines in the elderly aged ≥60 years.

Feasibility of left ventricular longitudinal strain measurement by speckle-tracking echocardiography in infants / 中华超声影像学杂志

Objective:To explore the clinical feasibility and application method of speckle-tracking echocardiography (STE) in assessing left ventricular longitudinal strain in infants.Methods:One hundred and ten infants within one week of birth were randomly selected in the Third Affiliated Hospital of Guangzhou Medical University from June 2019 to February 2020, and the basic data were collected. STE was performed by two physicians with more than 5 years′ experience.Images of the same infant were analyzed by physicians with 5 years′ experience and 2 years′ experience, respectively, and the difference and correlation of the results between the two doctors were analyzed. The images of the same infant were analyzed twice by the doctor with 5 years′ experience, and the differences and correlations between the results were analyzed. The infants were divided into different groups according to weight to compare the correlations between inter-physicians and intra-physician. STE analysis indicators included global left ventricular longitudinal peak strain (Glps-avg), four-chamber left ventricular longitudinal strain (Glps-A4C), three-chamber left ventricular longitudinal strain (Glps-A3C), two-chamber left ventricular longitudinal strain(Glps-A2C), left ventricular anterior wall longitudinal strain (Glps-a), anterior interventricular septum longitudinal strain(Glps-ais), posterior interventricular septum longitudinal strain (Glps-pis), inferior wall of left ventricle longitudinal strain (Glps-i), posterior wall of left ventricle longitudinal strain (Glps-p), lateral wall of left ventricle longitudinal strain (Glps-l), left ventricular basal section longitudinal strain (Glps-bs), left ventricular middle section longitudinal strain (Glps-ms) and left ventricular apex section longitudinal strain (Glps-as), a total of 13 indicators. The differences were analyzed by paired t test, and the correlations were determined by intra-group correlation coefficient (ICC). Results:According to the inclusion and exclusion criteria, 95 patients were included. For the 13 STE indicators, inter-physicians comparison: the differences between the two physicians were statistically significant (all P<0.05) except for Glps-pis, and the ICC were 0.38-0.72 (all P<0.01). Intra-physician comparison: the differences of these indicators between two measurements were not statistically significant (all P>0.05) except for Glps-ais and Glps-I, ICC were 0.31-0.76 (all P<0.05). Among them, inter-physicians and Intra-physician ICC of Glps-avg, Glps-bs, Glps-ms were 0.68/0.75, 0.72/0.66 and 0.65/0.76 respectively. The group comparison by infants′ weight showed that: In very low weight infants group, the ICC of inter-physicians and intra-physician ranged 0.82-0.93(all P<0.05) and 0.80-0.95(all P<0.05). In low weight infants group, the ICC of inter-physicians and intra-physician ranged 0.65-0.94 (all P<0.05) and 0.69-0.93 (all P<0.01). In the normal weight infants group, ICC of inter-physicians ranged 0.06-0.68, with statistical significance except for Glps-A3C (all P<0.05); ICC of intra-physician ranged 0.36-0.59 (all P<0.05). In overweight infants group, there was no statistical significance in ICC of inter-physicians (all P>0.05), the ICC of intra-physician, Glps-bs and Glps-ms groups were 0.63 and 0.77 (all P<0.05), with no statistical significance in other indicators (all P>0.05). Conclusions:Left ventricular longitudinal strain by STE in infants has better repeatability, and the consistency of intra-physician is higher than inter-physicians, among which the Glps-avg consistency is the best, followed by Glps-bs and Glps-ms. STE is more reproducible in low and very low weight infants than in normal and overweight infants.

Objective To investigate the current situation and annual trend of injuries among primary and middle school students in Changning District, Shanghai, and to provide scientific evidence for decision-making of prevention and control. Methods The monitoring data of various types of injuries was collected from the “cause of class absence” system during the 2010-2017 school years. The Joinpoint regression analysis was used to estimate the annual percent change and average annual percent change, and to perform the trend test. Results During the 2010-2017 school years in Changning District, a total of 2,286 cases of injuries occurred among primary and middle school students, with an injury rate of about 0.70%. The top three prevalent injury types were falls, traffic accidents, and burn-related injury. The results of Joinpoint trend analysis indicated that the incidence of total injuries in Changning District was generally decreasing, which was mainly due to the effective control of injuries caused by falls, traffic accidents, and burns, and to the decreasing injury incidence among primary school students. Conclusion The overall situation of injuries among primary and middle school students in Changning District has improved significantly, but falls and traffic accidents are still important health threats. More attentions should be paid to certain groups, such as vocational and special education students.

Phenotypic analysis and variant identification of a fetus with Joubert syndrome 17 / 中华医学遗传学杂志

OBJECTIVE@#To analyze the phenotype and genetic variant of a fetus with dysplasia of cerebellar vermis.@*METHODS@#Gestational status and family history of the gravida was taken in combination with the imaging results of the fetus. Following elected abortion, fetal tissue and peripheral blood samples of the couple were collected for the extraction of genome DNA. Whole exome sequencing was carried out to screen potential variant associated with the phenotype of the proband. Specific PCR primers were designed to verify the results by Sanger sequencing.@*RESULTS@#Prenatal ultrasound revealed that the fetal vermis cerebellum was poorly developed, which was similar to the previous pregnancy. Whole exome sequencing revealed that the fetus has carried compound heterozygous variants of the CPLANE1 gene, namely c.7978C>T and c.7169delT, which were respectively inherited from the husband and wife.@*CONCLUSION@#The c.7978C>T and c.7169delT compound heterozygous variants of the CPLANE1 gene probably underlay the dysplasia of cerebellar vermis in the fetus, which has provided a basis for genetic counseling and prenatal diagnosis.

National Nutrition and Health Systematic Survey for Children 0-17 Years of Age in China / 生物医学与环境科学（英文）

The main purpose of the National Nutrition and Health Systematic Survey for children 0-17 years of age in China (CNHSC) was to collect basic data on the nutrition, development, and health status for children in different regions across China using evidence-based, reliable, and cost-effective approaches. Children and their parents or guardians from seven regions (south, southwest, north, northwest, eastern, central, and northeast China) in China were recruited. A multi-stage stratified randomized sampling method was used. Two provinces were randomly sampled from each of the seven regions, from which one urban district and one rural country were also randomly sampled, resulting in a total of 28 survey counties/districts. Dietary surveys, health examinations, laboratory testing, and questionnaires were used to collect dietary intake, nutritional status, child development, and health status information. Nutrition, health, and lifestyle assessment of children and their parents was determined using the Knowledge Attitude Practice (KAP) survey. Greater than 100,000 children (38,000 children < 6 years of age and 66,000 children 6-17 years of age) completed the survey. The survey provided comprehensive data on child nutrition and health status for future studies and will serve as the basis for an integrated nutrition and health improvement strategies proposal for children in China.

Prenatal diagnosis for two fetuses carrying partial deletion of Y chromosome / 中华医学遗传学杂志

OBJECTIVE@#To perform prenatal diagosis for two fetuses carrying partial deletion of Y chromosome.@*METHODS@#Routine G- and C-banding were carried out to analyze the chromosomal karyotypes of the fetuses and their fathers. Fetal DNA was also subjected to low-coverage massively parallel copy number variation sequencing (CNV-seq), fluorescence in situ hybridization (FISH), SRY gene and AZF factor testing.@*RESULTS@#Both fetuses showed a 46, XN, del(Y) (q11.2) karyotype at 320-400 band level by the analysis of amniotic fluid chromosomes. FISH with Y chromosome centromere probe indicated that in both cases the number of Y chromosome was normal. Both fathers had an apparently normal karyotype at 320-400 band level. For fetus 1, CNV-seq test revealed a 12.88 Mb deletion at Yq11.221-q12, which encompassed the whole of AZFb+AZFc regions and may lead to male infertility, sperm deficiency and/or severe oligospermia. In fetus 2, CNV-seq also detected a 14.84 Mb deletion at Yq11.21-q12, which encompassed the whole of the AZF region and may lead to severe spermatogenesis disorder resulting in severe oligoasthenospermia and azoospermia. In both cases, testing of SRY gene was positive. No point mutation of the SRY gene was identified. Analysis of amniotic fluid DNA confirmed partial or total absence of AZF in the two fetuses, respectively.@*CONCLUSION@#Combined use of various technologies can enable accurate detection of structural abnormalities of the Y chromosome and facilitate genetic counseling. CNV-seq can help with rapid screening of Y chromosome microdeletions and may be used as a complementary test for chromosomal karyotyping.

Genetic diagnosis and noninvasive prenatal testing of a family with Williams-Beuren syndrome / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic basis of a fetus with ventricular septal defect (VSD) by using modified noninvasive prenatal testing (NIPT) for the detection of microdeletion syndromes.@*METHODS@#Chromosomal karyotypes of the fetus and its parents were analyzed by G-banding technique. Next generation sequencing (NGS) was used to detect genomic copy number variations (CNVs) in cell-free fetal DNA. The results were verified by fluorescence in situ hybridization (FISH).@*RESULTS@#The fetus and its parents all had a normal karyotype at 320-400 band level. NGS revealed a deletion of 1.30 Mb at 7q11.23 in the fetus, with a 93% overlap with that of Williams-Beuren syndrome (WBS). The father also had a deletion of 1.42 Mb at 7q11.23, with a 99% overlap with that of WBS. Modified NIPT also detected the 1.30 Mb deletion at 7q11.23 in the fetus. The result of FISH has confirmed the above results.@*CONCLUSION@#It is necessary to carry out genetic testing on fetuses with VSD. NGS can detect fetal microdeletion syndromes and help to trace their parental origin. The modified NIPT for fetal chromosomal microdeletions/microduplication syndromes is highly accurate.
