RESUMO
Background and Objectives@#Malnutrition is a serious public health problem in developing countries, including Indonesia. Based on RISKESDAS 2018, the prevalence of stunting aged 13-15 years in Takalar Regency is 24.83%. This study aimed to assess the prevalence of stunting and the determinants of stunting in adolescent girls aged 13-15 years in the South Galesong District, Takalar Regency.@*Methods@#This is a cross-sectional study using purposive sampling method that included 247 adolescent girls in selected junior high schools. Data collection used questionnaires and anthropometric measurements. An anthropometric measurement was converted to the indices of nutritional status using World Health Organization Anthro Plus software.@*Results@#The prevalence of stunting was 25.1%. Bivariate analysis showed determinant factors related significantly to stunting were energy intake (p<0.001), protein intake (p<0.001), iron intake (p<0.005), and zinc intake (p<0.001). Multivariate analysis showed determinant factors related significantly to stunting were zinc intake (p<0.001, OR=7.993), protein intake (p<0.05, OR=2.248), and knowledge level (p<0.05, OR=2.032).@*Conclusion@#The occurrence of stunting is related to the quality and quantity of food and the level of adolescent knowledge about balanced nutrition. It is necessary to hold educational programs and interventions on improving nutrition initiated by stakeholders and the department of health, in this case, the health center is needed to reduce stunting rates, especially among adolescents.

Objective: To compare the application of China growth standard for children under 7 years of age (China standards) and World Health Organization child growth standards (WHO standards) in evaluating the prevalence of malnutrition in children aged 0-<6 years in China. Methods: The research data came from the national special program for science & technology basic resources investigation of China, named "2019-2021 survey and application of China's nutrition and health system for children aged 0-18 years". Multi-stage stratified random sampling was used to recruit 28 districts (regions) in 14 provinces, autonomous regions or municipalities across the country. Children (n=38 848) were physically measured and questionnaires were conducted in the guardians of the children. The indicators of stunting, underweight, wasting, overweight and obesity were evaluated by China standards and WHO standards respectively. Chi-square test was used to comparing the prevalence of each nutritional status between the two standards, as well as the comparison between the two standards by gender and age. Results: Among the 38 848 children, 19 650 were boys (50.6%) and 19 198 were girls (49.4%), 19 480 urban children (50.1%) and 19 368 rural children (49.9%). The stunting, underweight and wasting cases in the study population were 2 090 children (5.4%), 1 354 children (3.5%) and 1 276 children (3.3%) according to the China standards, and 1 474 children (3.8%), 701 children (1.8%) and 824 children (2.1%) according to the WHO standards, respectively; the above rates according to the China standards were slightly higher than those to the WHO standards (χ2=111.59, 213.14, and 99.99, all P<0.001). The overweight and obesity cases in the study population were 2 186 children (5.6%) and 1 153 children (3.0%) according to the China standards, and 2 210 children (5.7%) and 1 186 children (3.1%) according to the WHO standards, with no statistically significant differences (χ2=0.14 and 0.48, P=0.709 and 0.488, respectively). Compared to the results based on WHO standards, the China standards showed a lower prevalence of overweight and obesity in boys (χ2=14.95 and 5.85, P<0.001 and =0.016, respectively), and higher prevalence of overweight in girls (χ2=12.60, P<0.001); but there was no statistically significant differences in girls' obesity prevalence between the two standards (χ2=2.62, P=0.106). Conclusions: In general, the prevalence of malnutrition among children aged 0-<6 years based on China standards is slightly higher than that on WHO standards. To evaluate the nutritional status of children, it is advisable to select appropriate child growth standards based on work requirements, norms or research objectives.

OBJECTIVES@#To investigate the nutritional status and its influencing factors in children with newly diagnosed inflammatory bowel disease (IBD).@*METHODS@#A retrospective analysis was conducted on the clinical data of children who were diagnosed with IBD for the first time in Hunan Children's Hospital from January 2015 to December 2021. Diagnostic delay was defined as the time from the symptom onset to IBD diagnosis being in the upper quartile (P76-P100) of all IBD children in the study. Multivariate logistic regression analysis was used to explore the risk factors for emaciation and growth retardation.@*RESULTS@#A total of 125 children with newly diagnosed IBD were included, with Crohn's disease being the main type (91.2%). The rates of emaciation and growth retardation were 42.4% (53 cases) and 7.2% (9 cases), respectively, and the rate of anemia was 77.6% (97 cases). Diagnostic delay was noted in 31 children (24.8%), with the time from the symptom onset to IBD diagnosis of 366 to 7 211 days. Multivariate logistic regression analysis showed that diagnostic delay was a risk factor for emaciation and growth retardation (OR=2.73 and OR=4.42, respectively; P<0.05) and that age was positively associated with emaciation (OR=1.30, P<0.05).@*CONCLUSIONS@#Children with newly diagnosed IBD have poor nutritional status, and the rates of anemia, emaciation, and growth retardation are high. Diagnostic delay is associated with malnutrition in children with IBD.

INTRODUCTION@#In the face of unchanging high rates of stunting among 12-23 months old Filipino babies, sustaining exclusive breastfeeding up to 6 months old remains a challenge. This study determined the effect of a breastfeeding reminder system on breastfeeding.@*METHODS@#This is a quasi-experimental study. Mothers were regularly given breastfeeding reminders by SMS and phone call. The weight, body length, episodes of upper respiratory tract infection and diarrhea were compared between the babies who were given exclusive breastfeeding and those whose exclusive breastfeeding was not sustained. Pearson Chi – square test and t-test at p=0.05 determined significance of differences of variables.@*RESULTS@#From March- October 2020, there were 450 babies included in the study. Of these babies, 44.8% were given exclusive breastfeeding up to 6 months. Timely initiation of breastfeeding was practiced by 91.95% of the mothers in the study. Babies who did not receive exclusive breastfeeding were shorter than those who received exclusive breastfeeding at 1 year old (70.11cm +2.78 vs.75.47cm +1.41, p<0.001) and at 2 years old (80.89 cm +2.30 vs. 87.29cm +1.47, p<0.001). At 2 years old, babies who received exclusive breastfeeding had no episodes of diarrhea and minimal (2%, p<0.001) episodes of acute respiratory infections.@*CONCLUSION@#Due to the implementation of the reminder system, the percentage of babies exclusively breastfed up to 6 months of age increased to 44%. This is a significant improvement compared to a previous study where only 29% of the babies were exclusively breastfed.At one and two years old, babies who were not exclusively breastfed had stunting, weighed less and had more infections (diarrhea and URTI).

This study aims to analyze the clinical characteristics and genetic variations of two cases with developmental delay and lactic acidosis in a family, and to explore the relationship between genetic variations and clinical features. A retrospective analysis was conducted on the clinical characteristics of two siblings with developmental delay and lactic acidosis who were treated at the Neonatal Department of Children's Hospital of Chongqing Medical University in May 2019 and December 2021, respectively. Whole-exome sequencing was used to detect genetic variations in the affected children. Homology modeling of the BCS1L protein was performed to analyze the structural and functional changes of the protein. The correlation between genetic variations and clinical phenotypes was analyzed. The results showed that the main clinical features of the two affected children in this family were manifestations of mitochondrial respiratory chain complex Ⅲ deficiency, including prematurity, developmental delay, respiratory failure, lactic acidosis, cholestasis, liver dysfunction, renal tubular lesions, coagulation dysfunction, anemia, hypoglycemia, hypotonia, and early death. Whole-exome sequencing revealed a novel deletion mutation c.486_488delGGA (p.E163del) and a novel missense mutation c.992C>T (p.T331I) in the BCS1L gene. Structural analysis of the homology modeling showed that the compound heterozygous mutation had a significant impact on protein function. In conclusion, the novel mutation site c.992C>T (p.T331I) in the BCS1L gene is a "likely pathogenic" mutation, and the compound heterozygous mutation is closely related to the phenotype of mitochondrial respiratory chain complex Ⅲ deficiency.

OBJECTIVE@#To analyze the genetic characteristics of a child with Meier-Gorlin syndrome (MGS) due to a homozygous variant of the ORC6 gene.@*METHODS@#A child who was admitted to the Children's Hospital Affiliated to Soochow University on March 25, 2019 due to growth retardation was selected as the study subject. Clinical data of the child was collected. Whole exome sequencing was carried out for the child. Candidate variant was validated by Sanger sequencing and bioinformatic analysis.@*RESULTS@#The child, a 8-year-and-3-month-old male, has featured short stature, small ears, bilateral cryptorchidism and patellar dysplasia. His parents were of first cousins. The child was found to harbor a homozygous c.712A>T (p.K238*) missense variant of the ORC6 gene, which may lead to premature termination of protein translation. Sanger sequencing confirmed that both of his parents were heterozygous carriers. Based on the guidelines from the American College of Medical Genetics and Genomics, the variant was classified as pathogenic (PVS1_Moderate+PM2_Supporting+PM3+PP3+PP4).@*CONCLUSION@#The homozygous c.712A>T (p.K238*) variant probably underlay the MGS in this child.

OBJECTIVE@#To explore the clinical and genetic characteristics of a boy with isolated maternal uniparental disomy of chromosome 20 [UPD(20)mat].@*METHODS@#A child who was admitted to the Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology on April 8,2021. was selected as the study subject. Phenotypic and endocrinological findings of the child were retrospectively analyzed. Whole exome sequencing (WES) and methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) were carried out for detecting the UPD sequences and copy number variations. Both of his parents were verified by Sanger sequencing. Relevant literature was systematically reviewed.@*RESULTS@#The child, a 3-year-and-8-month-old boy born to a 41-year-old mother by Cesarean delivery at 36+2 gestational weeks due to oligohydramia, had a birth weight of 2 300 g and length of 46 cm. He was admitted to the NICU for feeding difficulties which had persisted despite of clinical management. At the age of 3.75, he had a height of 92.5 cm (< 3rd percentile; 25th ~ 50th percentile at 2.5 years) and a weight of 10.8 kg (< 3rd percentile; 50th percentile at 15 months). He had also presented with growth retardation, short stature, attention deficit and hyperactivity disorder (ADHD), mild mental retardation, and speech and language development disorders. He had simian creases in both hands but no additional dysmorphic signs, and his motor development was normal. Serum insulin, thyroid-stimulating hormone, and insulin growth factor binding protein 3 levels were within the normal ranges, though insulin growth factor-1 (IGF-1) was slightly decreased. Since that time he had continuously used atomoxetine hydrochloride capsules to control his ADHD. WES and MS-MLPA revealed the existence of UPD (20)mat.@*CONCLUSION@#The UPD(20)mat syndrome is characterized by feeding difficulties, growth retardation and short stature. The child in our case has been accompanied by ADHD and speech and language development disorders, which required long-term treatment. For women with advanced maternal age and suggestive phenotypes, genetic testing and counseling should be conducted.

Short stature is a common physical developmental abnormality in children. Without timely and accurate diagnosis, as well as early intervention, it can impose a heavy burden on the children and their families. There are numerous causes for short stature, and the diagnostic process essentially involves identifying its underlying causes. Based on a thorough understanding of the regular patterns of child physical development and the characteristics of individuals at high risk of short stature, a scientific definition of short stature needs to be established, along with standardized diagnostic and treatment protocols, to achieve early diagnosis or referral for short stature. Furthermore, it is necessary to enhance scientific awareness of short stature among parents and primary care pediatricians, in order to avoid over-treatment, missed diagnoses, and misdiagnoses arising from "misconceptions", and to improve the scientific assessment of short stature.

OBJECTIVES@#To investigate the changes in the serum levels of Klotho, fibroblast growth factor 23 (FGF23), and insulin-like growth factor-1 (IGF-1) in children with idiopathic short stature (ISS) before and after recombinant human growth hormone (rhGH) treatment, as well as the correlation of Klotho and FGF23 with the growth hormone (GH)/IGF-1 growth axis in these children.@*METHODS@#A prospective study was conducted on 33 children who were diagnosed with ISS in the Department of Pediatrics, Hebei Provincial People's Hospital, from March 10, 2021 to December 1, 2022 (ISS group). Twenty-nine healthy children, matched for age and sex, who attended the Department of Child Healthcare during the same period, were enrolled as the healthy control group. The children in the ISS group were treated with rhGH, and the serum levels of Klotho, FGF23, and IGF-1 were measured before treatment and after 3, 6, and 9 months of treatment. A correlation analysis was conducted on these indexes.@*RESULTS@#There were no significant differences in the serum levels of IGF-1, Klotho, and FGF23 between the ISS and healthy control groups (P>0.05). The serum levels of Klotho, FGF23, and IGF-1 increased significantly in the ISS group after 3, 6, and 9 months of rhGH treatment (P<0.05). In the ISS group, Klotho and FGF23 levels were positively correlated with the phosphate level before treatment (P<0.05). Before treatment and after 3, 6, and 9 months of rhGH treatment, the Klotho level was positively correlated with the IGF-1 level (P<0.05), the FGF23 level was positively correlated with the IGF-1 level (P<0.05), and the Klotho level was positively correlated with the FGF23 level (P<0.05), while Klotho and FGF23 levels were not correlated with the height standard deviation of point (P>0.05).@*CONCLUSIONS@#The rhGH treatment can upregulate the levels of Klotho, FGF23, and IGF-1 and realize the catch-up growth in children with ISS. Klotho and FGF23 may not directly promote the linear growth of children with ISS, but may have indirect effects through the pathways such as IGF-1 and phosphate metabolism. The consistent changes in Klotho, FGF23 and IGF-1 levels show that there is a synergistic relationship among them in regulating the linear growth of ISS children.

Objective: To analyze the clinical characteristics of patients with Mucopolysaccharidosis ⅣA (MPS ⅣA). Methods: A retrospective study was conducted on 111 patients with MPS ⅣA in Xinhua Hospital of Shanghai Jiao Tong University School of Medcine from December 2008 to August 2020, confirmed by enzyme activity and genetic testing. General situation, clinical manifestations and enzyme activity test results were analyzed. According to the clinical manifestations, it can be divided into severe, intermediate and mild group. The independent sample t test was used to compare the birth body length and weight of children with that of normal boys and girls, and group comparisons of enzyme activities were evaluated by median test. Results: One hundred and eleven unrelated patients, 69 males and 42 females, were classified into 3 subtypes: severe (n=85), intermediate (n=14), and mild (n=12). The age at symptom onset were 1.6 (1.0, 3.0) years, and at diagnosis were 4.3 (2.8, 7.8) years. Skeletal manifestations were observed in all patients and consisted mainly of pectus carinatum (96/111, 86.5%), motor dysfunction (78/111, 70.3%), spinal deformity (71/111, 64.0%), growth retardation (64/111, 57.7%), joint laxity (63/111, 56.8%) and genu valgum (62/111, 55.9%). Eighty-eight patients (88/111, 79.3%) with MPS ⅣA were also along with non-skeletal manifestations, mainly including snoring (38/111, 34.2%), coarse faces (34/111, 30.6%), and visual impairment (26/111, 23.4%). The most common skeletal manifestation was pectus carinatum (79 cases), and non-skeletal manifestation was snoring (30 cases) and coarse faces (30 cases) in severe patients, pectus carinatum (13 cases) and snoring (5 cases) in intermediate type, motor dysfunction (11 cases) and snoring (3 cases) and visual impairment (3 cases) in mild patients. The height and weight of severe patients began to fall below -2 s at 2-<5 years and 5-<7 years, respectively. At the age of 10-<15 years, the standard deviation score of the height of severe patients reached (-6.2±1.6) s in males and (-6.4±1.2) s in females, and the score of weight got (-3.0±1.1) s in males and (-3.5±0.5) s in females. The height of intermediate patients began to fall below -2 s at the age of 7-<10 years, and the standard deviation score of height were -4.6 s and -3.6 s in 2 males, and -4.6 s and -3.8 s in 2 females at the age of 10-<15 years. The weight remained within -2 s in 72.0% (18/25) of intermediate patients compared to age-matched healthy children. In the mild patients with MPS ⅣA, the mean standard deviation score of height and weight was within -2 s. The enzyme activities of mild patients (2.02 (1.05, 8.20) nmol/(17 h·mg)) were both significantly higher than that of intermediate (0.57 (0.47, 0.94) nmol/(17 h·mg)) and severe (0.22 (0, 0.59) nmol/(17 h·mg)) patients (Z=9.91, 13.98, P=0.005, 0.001), and the enzyme activity of intermediate patients was significantly higher than that of severe patients (Z=8.56, P=0.010). Conclusions: The clinical manifestations of MPS ⅣA are charactered by pectus carinatum, motor function impairment, spinal deformity and growth retardation. The clinical characteristics, growth rate and enzyme activity differ among the 3 subtypes of MPS ⅣA.

OBJECTIVE@#To explore the clinical phenotypes and genetic diagnosis of 2 sporadic cases for cleidocranial dysplasia.@*METHODS@#The clinical data of two cases of CCD admitted to the Third Affiliated Hospital of Zhengzhou University on December 16, 2021 and December 9, 2021 were analyzed retrospectively, and the whole exome sequencing (WES), chromosome microarray analysis and copy number variation sequencing were performed.@*RESULTS@#The main ultrasonographic findings of the fetus had included poorly calcified skull bones, budging of parieto-occipital area, compression and deformation of skull, and loss of nasal bone. The infant's clinical phenotypes included delayed closure of anterior fontanelle, recurrent respiratory tract infection, growth retardation, and clavicular hypoplasia. By WES analysis, the fetus was found to harbor a heterozygous c.911_914delinsTTT variant of the RUNX2 gene, whilst the infant was found to harbor a heterozygous c.1008delT variant of the RUNX2 gene. Both variants were verified by Sanger sequencing to have occurred de novo.@*CONCLUSION@#For sporadic cases featuring cleidocranial dysplasia, prenatal ultrasonography is particularly important. Hypoplastic clavicle, skull calcification and nasal bone absence are the main features. Diagnosis should also be suspected for infants featuring growth retardation, recurrent respiratory tract infections and clavicular dysplasia. The identification of the c.911_914delinsTTT and c.1008delT variants of the RUNX2 gene has facilitated genetic counseling and prenatal diagnosis, and also expanded the mutational spectrum of the RUNX2 gene.

染色质许可和DNA复制因子1(Cdt1)是复制起始许可的主要调控因子,也是组成复制前复合物的核心成员。细胞通过依赖Cdt1的波动水平,且在每个周期中通过调节其总量以确保DNA仅复制一次。Cdt1功能缺陷会造成DNA过度复制,最终导致基因组不稳定。虽然酵母中cdt1和人类Meier-Gorlin综合征(MGS)患者中的CDT1已被广泛研究,但缺乏脊椎动物模型。我们发现在硬骨鱼类分支的几个鲤形目物种(包括斑马鱼)中,Cdt1蛋白在其N末端插入一段其他脊椎动物中没有的独特无序序列。通过分析在cdt1基因中携带移码缺失的遗传性斑马鱼突变体(命名为cdt1zju1 ),我们发现突变胚胎虽然几乎无任何早期胚胎表型异常,但成年突变斑马鱼却表现出侏儒症、生存能力降低的症状,以及性腺发育不全且不育。此外,我们同样发现除转录本cdt1-201外,斑马鱼还存在第二个cdt1转录本——cdt1-202,它是通过跳过外显子2产生,这在其他生物中暂无报道。有意思的是cdt1-202在cdt1-201纯合突变体中显著上调。上述研究结果表明,cdt1-202转录本可能可以补偿cdt1-201在早期发育过程中的功能损失,但不能补偿后期生长,这可支持斑马鱼作为研究人类MGS的遗传模型。

The anterior disc displacement (ADD) leads to temporomandibular joint osteoarthritis (TMJOA) and mandibular growth retardation in adolescents. To investigate the potential functional role of fibrocartilage stem cells (FCSCs) during the process, a surgical ADD-TMJOA mouse model was established. From 1 week after model generation, ADD mice exhibited aggravated mandibular growth retardation with osteoarthritis (OA)-like joint cartilage degeneration, manifesting with impaired chondrogenic differentiation and loss of subchondral bone homeostasis. Lineage tracing using Gli1-CreER+; Tmfl/-mice and Sox9-CreER+;Tmfl/-mice showed that ADD interfered with the chondrogenic capacity of Gli1+ FCSCs as well as osteogenic differentiation of Sox9+ lineage, mainly in the middle zone of TMJ cartilage. Then, a surgically induced disc reposition (DR) mouse model was generated. The inhibited FCSCs capacity was significantly alleviated by DR treatment in ADD mice. And both the ADD mice and adolescent ADD patients had significantly relieved OA phenotype and improved condylar growth after DR treatment. In conclusion, ADD-TMJOA leads to impaired chondrogenic progenitor capacity and osteogenesis differentiation of FCSCs lineage, resulting in cartilage degeneration and loss of subchondral bone homeostasis, finally causing TMJ growth retardation. DR at an early stage could significantly alleviate cartilage degeneration and restore TMJ cartilage growth potential.

Stunting is a significant public health problem in low- and middle-income countries. This study assessed the prevalence of stunting and associated risk factors of stunting among preschool and school-going children in flood-affected areas of Pakistan. A cross-sectional study was conducted by visiting 656 households through multi-stage sampling. Respondent's anthropometric measurements, socio-demographic information and sanitation facilities were explored. A logistic regression model was used to determine determinants of stunting, controlling for all possible confounders. The overall prevalence of stunting in children was 40.5%, among children 36.1% boys and 46.3% of girls were stunted. The prevalence of stunting in under-five children was 50.7%. Female children (OR=1.35, 95% CI:0.94-2.0), children aged 13-24 months (OR=6.5, 95% CI: 3.0-13.9), mothers aged 15-24 years (OR=4.4, 95% CI: 2.6-7.2), joint family (OR=2.1, 95% CI: 1.4-3.0) did not have access to improved drinking water (OR=3.3, 95% CI: 1.9-5.9), and the toilet facility (OR=2.8, 95% CI, 1.9-4.3), while the children from district Nowshera (OR=1.7, 95% CI: 0.9-3.2) were significantly (P<0.05) associated in univariate analysis. The regression model revealed that child age, maternal age, family type, quality of water, and toilet facility, were the significant (P<0.05) factors contributing to child stunting in the flood-hit areas. Identification of key factors might be helpful for policymakers in designing comprehensive community-based programs for the reduction of stunting in flood-affected areas. In disasters such as flood, the detrimental consequences of the stunting problem could be even more on children. Evidence-based education and care must be provided to the families in the flood-affected regions to reduce the stunting problem. The determinants of stunting should be targeted by making comprehensive policies regarding proper nutrition, livelihood, clean water, and sanitation facilities in flood-hit regions.
A baixa estatura é um problema significativo de saúde pública em países de baixa e média renda. Este estudo avaliou a prevalência de nanismo e os fatores de risco associados de nanismo entre crianças em idade pré-escolar e em idade escolar em áreas afetadas por inundações do Paquistão. Foi realizado um estudo transversal visitando 656 domicílios por meio de amostragem em múltiplos estágios. As medidas antropométricas do entrevistado, informações sociodemográficas e instalações de saneamento foram exploradas. Um modelo de regressão logística foi usado para determinar os determinantes do nanismo, controlando todos os possíveis fatores de confusão. A prevalência geral de baixa estatura em crianças foi de 40,5%, entre as crianças 36,1% dos meninos e 46,3% das meninas com baixa estatura. A prevalência de baixa estatura em crianças menores de 5 anos foi de 50,7%. Crianças do sexo feminino (OR = 1,35, IC de 95%: 0,94-2,0), crianças de 13-24 meses (OR = 6,5, IC de 95%: 3,0-13,9), mães de 15-24 anos (OR = 4,4, IC de 95%: 2,6-7,2), família conjunta (OR = 2,1, IC 95%: 1,4-3,0) não tiveram acesso a água potável de qualidade (OR = 3,3, IC 95%: 1,9-5,9) e a banheiro (OR = 2,8, IC de 95%, 1,9-4,3), enquanto as crianças do distrito de Nowshera (OR = 1,7, IC de 95%: 0,9-3,2) foram significativamente (P < 0,05) associadas na análise univariada. O modelo de regressão revelou que a idade da criança, idade materna, tipo de família, qualidade da água e banheiro foram os fatores significativos (P < 0,05) que contribuíram para a baixa estatura infantil nas áreas afetadas pelas enchentes. A identificação de fatores-chave pode ser útil para os formuladores de políticas no planejamento de programas comunitários abrangentes para a redução da baixa estatura em áreas afetadas pelas enchentes. Em desastres como enchentes, as consequências prejudiciais do problema de baixa estatura podem ser ainda maiores para as crianças. Educação baseada em evidências e cuidados deve ser fornecida às famílias nas regiões afetadas pelas enchentes para reduzir o problema de nanismo. Os determinantes do retardo de crescimento devem ser almejados pela formulação de políticas abrangentes sobre nutrição adequada, meios de subsistência, água potável e instalações de saneamento nas regiões afetadas pelas enchentes.

Pergunta: A somatropina é eficaz e segura para promover aumento da curva de crescimento em crianças nascidas PIG? Métodos: Levantamento bibliográfico foi realizado na base de dados PUBMED, seguindo estratégias de buscas predefinidas. Foi feita avaliação da qualidade metodológica das revisões sistemáticas com a ferramenta AMSTAR-2 (A MeaSurement Tool to Assess systematic Reviews version 2). Resultados: Foi selecionada uma revisão sistemática que atendeu aos critérios de inclusão. Conclusão: evidências de moderada certeza indicam que somatropina é eficaz e segura para tratamento de crianças nascidas PIG, pois promove recuperação do crescimento e não há relatos de eventos adversos graves na literatura científica
Technology: Somatropin. Indication: Growth disorder in children born small for gestational age (SGA). Question: Is somatropin effective, safe and cost effective for promoting height gain in children born SGA? Methods: A bibliographic search was done in PUBMED database, following predefined search strategies. The methodological quality of systematic reviews was evaluated using the AMSTAR-2 tool (A MeaSurement Tool to Assess systematic Reviews version 2). Results: Only a systematic review met the inclusion criteria and was selected. Conclusion: Evidence of moderate certainty indicates that somatropin is effective and safe for the treatment of children born SGA, because the treatment improve the growth and there are no reports of serious adverse events in the scientific literature

Objective: To understand the growth retardation among primary and secondary school students in areas covered by the Nutrition Improvement Program for Rural Compulsory Education Students and its influencing factors to provide evidence for improving the nutrition status of rural students in China. Methods: The multi-stage cluster random sampling method selected 1 550 969 primary and secondary school students aged 6-15 years from China's central and western regions. The ratio of male and female students was balanced. The height was measured, and the growth retardation of students was determined according to the Screening Criteria for School-age Children and Adolescents malnutrition (WS/T 456-2014), from the school and county questionnaire survey related factors. The number of cases and percentages described the growth retardation of students, and the χ2 test was used for comparison between groups. Binary logistic regression was used to analyze students' growth retardation factors. Results: In 2019, the growth retardation rate of primary and secondary school students in areas covered by the Nutrition Improvement Program for Rural Compulsory Education Students was 5.7% (88 631/1 550 969), the growth retardation rate in the western part (7.1%, 66 167/927 954) was higher than that in the central part (3.7%,19 511/533 973) with difference statistically significant (P<0.001). The growth retardation rate of the boys (6.3%,50 665/803 851) were higher than that of girls (5.1%, 37 966/747 118), the difference was statistically significant (P<0.001). The growth retardation rate of primary school students in central China was 3.9%(14 914/380 598), higher than that of junior middle school students (3.0%,4 597/153 375, P<0.001). In contrast, the growth retardation rate of the western junior high school students (7.2%, 21 494/297 217) were higher than that of elementary school students (7.1%, 44 673/630 737), with a difference statistically significant (all P=0.009). Multi-factor logistic regression results showed that, in high income area (OR=0.829, 95%CI: 0.816-0.842, P<0.001), parents providing part of the meal cost (OR=0.948, 95%CI: 0.931-0.965, P<0.001), enterprises providing meals (OR=0.845, 95%CI: 0.805-0.887, P<0.001), schools providing milk (OR=0.780, 95%CI: 0.767-0.793, P<0.001), health education courses (OR=0.702, 95%CI: 0.682-0.723, P<0.001) and other local nutrition improvement efforts (OR=0.739, 95%CI: 0.720-0.758, P<0.001) were negatively correlated with the occurrence of growth retardation, The growth retardation rate of the students was lower. Conclusions: There appeared significant regional, gender, and age differences in the growth retardation rate of primary and middle school students in areas covered by the Nutrition Improvement Program for Rural Compulsory Education Students. Appropriate food supply in schools, health education courses, and parental participation in nutritional improvement was related to children's lower growth retardation rate.

Objective: To summarize and analyze the clinical characteristics and gene mutations of 6 patients with Wiedemann-Steiner syndrome (WDSTS). Methods: To review and analyze the clinical data, including general conditions, clinical manifestations, growth hormone, cranial or pituitary gland magnetic resonance imaging (MRI),gene results and other data, 6 cases with WDSTS admitted to the Department of Endocrinology, Genetics and Metabolism of Jiangxi Provincial Children's Hospital and the Department of Child Care of Pingxiang Maternity and Child Care from April 2017 to February 2021 were recruited. Results: Of the 6 patients, 2 were male and 4 were female. The age of the first visit ranged from 1.0 to 11.2 years. All the 6 children presented with growth retardation and mental retardation and they all had typical facial dysmorphism and hypertrichosis (mainly on the back and limbs). Among them, case 5 had a growth hormone deficiency, and case 2 and 4 had abnormalities revealed by cranial MRI. Variations in KMT2A gene were identified in these 6 patients: c.10900+2T>C,c.10837C>T(p.Gln3613*), c.4332G>A(p.E1444E), c.2508dupC(p.W838Lfs*9), c.11695_11696delinsT(p.T3899Sfs*73), c.9915dupA (p.P3306Tfs*22).Among these variations, c.4332G>A, c.11695_11696delinsT and c.9915dupA were novel mutations. Therefore, the final diagnosis of these patients was WDSTS. Conclusions: Patients presented with short stature and mental retardation, typical facial dysmorphism and hypertrichosis should be considered WDSTS. Whole-exome sequencing plays an important role in disease diagnosis and genetic counseling.
