Abstract
Licha black (LI) pig has the specific characteristics of larger body length and appropriate fat deposition among Chinese indigenous pigs. Body length is one of the external traits that affect production performance, and fat deposition influences meat quality. However, the genetic characteristics of LI pigs have not yet been systematically uncovered. Here, the genomic information from 891 individuals of LI pigs, commercial pigs, and other Chinese indigenous pigs was used to analyze the breed characteristics of the LI pig with runs of homozygosity, haplotype, and FST selection signatures. The results showed the growth traits-related genes (i.e., NR6A1 and PAPPA2) and the fatness traits-related gene (i.e., PIK3C2B) were the promising candidate genes that closely related to the characteristics of LI pigs. In addition, the protein–protein interaction network revealed the potential interactions between the promising candidate genes and the FASN gene. The RNA expression data from FarmGTEx indicated that the RNA expression levels of NR6A1, PAPPA2, PIK3C2B, and FASN were highly correlated in the ileum. This study provides valuable molecular insights into the mechanisms that affect pig body length and fat deposition, which can be used in the further breeding process to improve meat quality and commercial profitability.

Relationship Between Serum Brain-Type Natriuretic Peptide and Biomarkers of Growth in Infants With Shunt-Dependent Single Cardiac Ventricle. Am J Cardiol 2022; 171:146-150. [PMID: 35287945 DOI: 10.1016/j.amjcard.2022.01.052] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 01/20/2022] [Accepted: 01/25/2022] [Indexed: 11/24/2022]
Abstract
For infants with shunt-dependent or ductal-dependent single ventricle heart disease, poor growth is common and associated with morbidity and impaired neurodevelopmental outcomes. Although attention has focused on nutrition to promote weight gain, little is known about the relation between heart failure and growth factors. A prospective observational pilot study was performed to assess the relation between heart failure, assessed by brain natriuretic peptide (BNP), and growth factors (insulin-like growth factor 1 [IGF-1] and insulin-like growth factor-binding protein 3) at 3 visits: (1) before discharge from neonatal intervention with the establishment of stable pulmonary blood flow, (2) immediately before superior cavopulmonary connection, and (3) before discharge after superior cavopulmonary connection operation. The relation between BNP and growth factors was analyzed using Spearman pairwise correlations at each visit and modeled over time with a linear mixed-effects model. Correlations were considered worthy of further exploration using a p <0.10, given the exploratory nature of the study. The study included 38 infants (66% male, 68% hypoplastic left heart syndrome). Median BNP was elevated at visit 1 and decreased over time (287 pg/dl [interquartile range 147 to 794], 85 pg/dl [52 to 183], and 90 pg/dl [70 to 138]). Median IGF-1 Z score was <0 at each visit but increased over time (-0.9 [interquartile range -1.1 to 0.1], -0.7 [-1.2 to 0.1], and -0.5 [-1.2 to 0]). Inverse correlations were found between BNP and IGF-1 at visit 1 (r = -0.40, p = 0.097), BNP and IGF-1 and insulin-like growth factor-binding protein 3 at visit 2 (r = -0.33, p = 0.080 and r = -0.33, p = 0.085, respectively) and BNP and IGF-1 Z score at visit 3 (r = -0.42, p = 0.049). Significant relations were likewise found between the change in BNP and the change in IGF-1 between visits 1 and 3 (p = 0.046) and between visits 2 and 3 (p = 0.048). In conclusion, this pilot study demonstrates an inverse correlation between BNP and growth factors, suggesting that the heart failure state associated with this physiology may play a mechanistic role in impaired growth.

Mei H, Xie R, Li T, Chen Z, Liu Y, Sun C. Effect of Atomoxetine on Behavioral Difficulties and Growth Development of Primary School Children with Attention-Deficit/Hyperactivity Disorder: A Prospective Study. CHILDREN 2022; 9:children9020212. [PMID: 35204932 PMCID: PMC8870549 DOI: 10.3390/children9020212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 02/03/2022] [Accepted: 02/04/2022] [Indexed: 11/16/2022]
Abstract
(1) Objective: Atomoxetine is a selective norepinephrine reuptake inhibitor used to treat attention-deficit/hyperactivity disorder (ADHD) in children over six years old. Although it is common knowledge that primary school children with ADHD often present with difficulties in the morning prior to school and in the evening, these two periods, and the family interactions they involve, are often neglected in studies of ADHD. Questionnaire–Children with Difficulties (QCD) has been widely used in China to evaluate parents’ perceptions of ADHD and patients’ daily behaviors during different times. In the long term, the efficacy and safety of atomoxetine have been well established in previous studies. Still, the short-term effects of atomoxetine treatment on serum growth parameters, such as IGF-1, IGFBP-3, and thyroid function, are not well documented. Therefore, this study was the first one using the QCD to quantify the efficacy of atomoxetine treatment in the morning prior to school and in the evening, and has investigated the possible influence on the growth parameters of Chinese primary school children with ADHD. (2) Method: This prospective study was conducted at the Department of Pediatrics at the Affiliated Hospital of Jiangnan University from August 2019 to February 2021. Changes in the children’s behavior and core ADHD symptoms following treatment were assessed using three parent-reported questionnaires, including Children with Difficulties (QCD), the Swanson, Nolan, and Pelham IV scale (SNAP-IV), and the Conners’ parents rating scales (CPRS). The height, weight, and body mass index (BMI) were measured and corrected to reflect the standard deviations (SDS) in Chinese children based on age and gender. Serum growth parameters, such as insulin-like growth factor 1 (IGF-1), insulin-like growth factor-binding protein 3 (IGFBP-3), and thyroid function, were also measured to assess the children’s growth development. Any adverse drug reactions were assessed every three weeks. (3) Result: Finally, 149 children were enrolled in this study, and they completed 12 weeks of atomoxetine treatment. The QCD results indicated that the atomoxetine treatment could significantly alleviate behavioral difficulties in primary children with ADHD, especially in the morning prior to school (p < 0.001, r = 0.66) and in the evening (p < 0.001, r = 0.73). A statically significant decrease in weight SDS (p < 0.05) was noted during treatment, but the effect size was slight (r = 0.09). The atomoxetine treatment had no significant impact on height SDS, BMI SDS, and serum growth parameters, such as the levels of IGF-1, IGFBP-3, and thyroid function. The SNAP-IV results showed a significant improvement in the core symptoms of ADHD, while the CPRS results indicated a significant improvement in controlling ADHD symptoms across two different domains, learning problems (r = 0.81) and hyperactivity (r = 0.86). No severe adverse reactions were observed in the course of treatment, and the most common adverse reactions were gastrointestinal symptoms. (4) Conclusions: Atomoxetine is an effective and safe treatment for primary school children with ADHD. In China, it may be an excellent choice to alleviate parenting stress and improve the condition of primary school children with ADHD. Moreover, our study indicated that the serum levels of IGF-1 and IGFBP-3 were within the normal range in newly diagnosed ADHD children, and atomoxetine will not affect the serum concentration of growth parameters, such as IGF-1, IGFBP-3, and thyroid function, in the short term. However, the treatment may reduce appetite, resulting in a reduction in the Children’s weight for a short period. Further observational studies to monitor the long-term effects of atomoxetine on primary school children are recommended.

Longitudinal evaluation of breast tissue in healthy infants: Prevalence and relation to reproductive hormones and growth factors. Front Endocrinol (Lausanne) 2022; 13:1048660. [PMID: 36531497 PMCID: PMC9751745 DOI: 10.3389/fendo.2022.1048660] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Accepted: 11/18/2022] [Indexed: 12/02/2022] Open
Abstract
INTRODUCTION Breast tissue in infancy is a rather undescribed phenomenon. We aimed to describe the prevalence and progression of palpable breast tissue in healthy boys and girls aged 0-1 years and to evaluate clinical markers, individual serum hormone concentrations as well as combined hormone profiles as determinants of the persistence of breast tissue. METHODS In total, 233 term infants (119 boys, 114 girls) were included and followed from birth until 1 year of age in The COPENHAGEN Minipuberty Study (ClinicalTrials.gov #NTC02784184). Infants were followed up to six times with a clinical examination and serum sampling. Principal component analyses (PCAs) produced combined hormone profiles. RESULTS A total of 98% of all infants aged 0-1 year exhibited breast tissue at some point. 50% still had breast tissue present at 0.5-0.6 years in girls and 0.3-0.4 years in boys ('persistent'). At one year, more girls than boys had breast tissue present (p=0.010). Most clinical and hormonal markers did not differ in infants with/without persistent breast tissue. However, in those with persistent breast tissue, estradiol (first visit, girls, p=0.034), androstenedione, corticosterone, cortisol (first visit, boys, all p<0.050), length (first visit, boys, p=0.030), and testicular volume (0.3-0.4 years, p=0.040) were higher, while IGF-I (0.3-0.4, boys, p=0.033) was lower. In boys, a combined, PCA-derived hormone profile (first visit) was able to predict the persistence of breast tissue (area under the curve=83%) better than any single marker. DISCUSSION Palpable breast tissue in infancy is common in both sexes although it persists in significantly more girls than boys at one year of age. Data supports both the early origin of breast tissue (in utero- and early postnatal) as well as a role of endogenous hormone production in later development and maintenance.
