In conclusion, FGF2 positively regulates osteoclastogenesis via stimulating the ERK-CREB pathway. These findings establish the importance of FGF2 in bone homeostasis, hinting the potential use of FGF2/ERK/CREB specific inhibitors to fight against bone-related disorders, such as osteoporosis.
To establish a reference nomogram for end-tidal CO corrected for ambient CO (ETCOc) levels in term and late-preterm Chinese newborns and then assess its efficacy to identify hemolytic hyperbilirubinemia.

We conducted a prospective study by measuring concurrent ETCOc and total serum bilirubin (TSB) or transcutaneous bilirubin (TcB) levels collected postnatally at 12, 24, 48, 72, 96, and 120hours of age. ETCOc at the 25th, 50th, 75th, and 95th percentiles at each epoch were used to construct the reference nomogram. We then explored the ability of predischarge ETCOc and TSB/TcB metrics to predict the development of hyperbilirubinemia requiring phototherapy in early postnatal period and jaundice readmission in late postnatal period.

Our nomogram, based on 990 measurements from 455 infants who were not nonhemolytic, displayed a steady line within 3 postnatal days, followed by a subsequent decline. From a cohort of infants with a serial ETCOc measurements (n=130) and those readmitted (n=21), we found that ETCOc and TSB/TcB ≥75th percentile can identify most hemolytic hyperbilirubinemia between 12 and 72hours after birth with an area under the curve (AUC) of 0.741. An ETCOc ≥1.7ppm alone between 96 and 120hours after birth can identify most hemolytic hyperbilirubinemia with an AUC of 0.816. In addition, 90.5% of readmitted infants had an ETCOc ≥75th percentile.

An ETCOc reference nomogram during the first 5 postnatal days in nonhemolytic term and late-preterm newborns can be used to identify hemolytic hyperbilirubinemia requiring phototherapy in the early postnatal period and readmission in the late postnatal period.

To investigate the prevalence of hemophagocytic lymphohistiocytosis (HLH) syndrome in pediatric acute liver failure (PALF) of infancy and assess the diagnostic role of rapid immunologic tests, genotype/phenotype correlations, and clinical outcomes.

We retrospectively analyzed 78 children with PALF aged <24months referred over almost 2 decades. The studied patients with a phenotype of HLH syndrome had a comprehensive immunologic workup, including additional genetic analysis for primary immunologic causes.

Thirty of the 78 children had the HLH phenotype and underwent genetic assessment, which demonstrated positive findings in 19 (63.3%), including 9 (30%) with biallelic primary HLH mutations and 10 (33.3%) with heterozygous mutations and/or polymorphisms. The most common form of primary HLH was familial hemophagocytic lymphohistiocytosis (FHL)-2, diagnosed in 6 children, 4 of whom had a c.50delT (p.Leu17ArgfsTer34) mutation in the PRF1 gene. Three patients with primary HLH received genetic diagnoses ofn approximately one-third of infants with indeterminate PALF (iPALF) who meet the clinical criteria for HLH, often leading to their death. The most common HLH type in iPALF is FHL-2, caused by biallelic mutations in PRF-1. signaling pathway The clinical relevance of observed heterozygous mutations and variants of uncertain significance requires further investigation. Prompt hematopoietic stem cell transplantation could be life-saving in infants who survive the liver injury.
To describe the epidemiology of pericardial effusion in hospitalized children and evaluate risk factors associated with the drainage of pericardial effusion and hospital mortality.

A retrospective study of a national pediatric discharge database.

We analyzed hospitalized pediatric patients from the neonatal age through 20years in the Kids' Inpatient Database 2016, extracting the cases of pericardial effusion. Of the 6 266 285 discharged patients recorded, 6417 (0.1%) were diagnosed with pericardial effusion, with the highest prevalence of 2153 patients in teens (13-20years of age). Pericardial effusion was drained in 792 (12.3%), and the adjusted risk of pericardial drainage was statistically low with rheumatologic diagnosis (OR, 0.485; 95% CI, 0.358-0.657, P<.001). The overall mortality in children with pericardial effusion was 6.8% and 10.9% of those who required pericardial effusion drainage (P<.001). The adjusted risk of mortality was statistically high with solid organ tumor (OR, 1.538; 95% CI, 1.056-2.239, P=.025) and pericardial drainage (OR, 1.430; 95% CI, 1.067-1.915, P=.017) and low in all other age groups compared with neonates, those with cardiac structural diagnosis (OR, 0.322; 95% CI, 0.212-0.489, P<.001), and those with rheumatologic diagnosis (OR, 0.531; 95% CI, 0.334-0.846, P=.008).

The risk of mortality in hospitalized children with pericardial effusion was higher in younger children with solid organ tumors and those who required pericardial effusion drainage. In contrast, it was lower in older children with cardiac or rheumatologic diagnoses.

To investigate the prevalence and characteristics of children with nonalcoholic fatty liver disease (NAFLD) who reduce their body mass index (BMI) z-score (BMIz) by >.25, a goal in obesity medicine, and to determine the BMIz decrease needed for serum aminotransferase normalization.

This retrospective, single-center study included patients aged <18years followed for NAFLD. Patients who had undergone weight loss surgery or had other reasons for weight loss/gain were excluded. Logistic regression was used to determine the odds of achieving a BMIz change of >-.25, as well as predictors of this outcome.

Of the 784 children who met the study criteria (median age, 13years; 66% male; 24% Hispanic), 541 had a lowest BMIz at >90days following the baseline clinic visit. Of these children, 168 (31%) had a BMIz change of >-.25 from baseline over a median of 367days (IQR, 201-678days). Decreases in serum aminotransferase and lipid levels were seen in both groups (with and without a BMIz change of >-.25); however, these decreases were more pronounced in children who achieved a BMIz drop of >.25. Hemoglobin A1c concentration did not change in either group. Young age (OR, .861; 95% CI, .81-.92; P<.01) and non-Hispanic ethnicity (OR of non-Hispanic vs Hispanic, .61; 95% CI, .38-.97; P<.04) were predictors of a BMIz change>-.25. The BMIz decrease associated with normalization of serum alanine aminotransferase was .27.

A BMIz reduction of >.25 is associated with significant changes in serum aminotransferase levels. These findings can further guide the clinical management of children with NAFLD.

This persistent inflammation is often called "inflammageing" and likely contributes to frailty progression. Preclinical models such as ageing and/or genetically modified mice offer a unique opportunity to mechanistically study how these inflammatory mediators affect frailty. In this review, we summarize and contrast evidence relating cytokines/chemokines to frailty in humans and in mouse models of frailty. In humans and mice, higher levels of the pro-inflammatory cytokine interleukin-6 regularly increased in proportion to the degree of frailty. Evidence linking other cytokines/chemokines to frailty in humans and mice is less certain. The chemokines CXCL-10 and monocyte chemoattractant protein-1 related to frailty across both species, but evidence is limited and inconsistent. Several other cytokines/chemokines, including tumour necrosis factor-α relate to frailty in humans or in mice, but evidence to date is species- and tissue-dependent. It is important for future studies to validate common mechanistic inflammatory biomarkers of frailty between humans and mice. Achieving this goal will accelerate the search for drugs to treat frailty.The soil-dwelling bacterium Pseudomonas putida S16 can survive on nicotine as its sole carbon and nitrogen source. The enzymes nicotine oxidoreductase (NicA2) and pseudooxynicotine amine oxidase (Pnao), both members of the flavin-containing amine oxidase family, catalyze the first two steps in the nicotine catabolism pathway. Our laboratory has previously shown that, contrary to other members of its enzyme family, NicA2 is actually a dehydrogenase that uses a cytochrome c protein (CycN) as its electron acceptor. The natural electron acceptor for Pnao is unknown; however, within the P. putida S16 genome, pnao forms an operon with cycN and nicA2, leading us to hypothesize that Pnao may also be a dehydrogenase that uses CycN as its electron acceptor. Here we characterized the kinetic properties of Pnao and show that Pnao is poorly oxidized by O2, but can be rapidly oxidized by CycN, indicating that Pnao indeed acts as a dehydrogenase that uses CycN as its oxidant. Comparing steady-state kinetics with transient kinetic experiments revealed that product release primarily limits turnover by Pnao. We also resolved the crystal structure of Pnao at 2.60 Å, which shows that Pnao has a similar structural fold as NicA2. Furthermore, rigid-body docking of the structure of CycN with Pnao and NicA2 identified a potential conserved binding site for CycN on these two enzymes. Taken together, our results demonstrate that although Pnao and NicA2 show a high degree of similarity to flavin containing amine oxidases that use dioxygen directly, both enzymes are actually dehydrogenases.Faithful translation of the genetic code is critical for the viability of all living organisms. The trans-editing enzyme ProXp-ala prevents Pro to Ala mutations during translation by hydrolyzing misacylated Ala-tRNAPro that has been synthesized by prolyl-tRNA synthetase. Plant ProXp-ala sequences contain a conserved C-terminal domain (CTD) that is absent in other organisms; the origin, structure, and function of this extra domain are unknown. To characterize the plant-specific CTD, we performed bioinformatics and computational analyses that provided a model consistent with a conserved α-helical structure. We also expressed and purified wildtype Arabidopsis thaliana (At) ProXp-ala in Escherichia coli, as well as variants lacking the CTD or containing only the CTD. Circular dichroism spectroscopy confirmed a loss of α-helical signal intensity upon CTD truncation. Size-exclusion chromatography with multiangle laser-light scattering revealed that wildtype At ProXp-ala was primarily dimeric and CTD truncation abolished dimerization in vitro. Furthermore, bimolecular fluorescence complementation assays in At protoplasts support a role for the CTD in homodimerization in vivo. The deacylation rate of Ala-tRNAPro by At ProXp-ala was also significantly reduced in the absence of the CTD, and kinetic assays indicated that the reduction in activity is primarily due to a tRNA binding defect. Overall, these results broaden our understanding of eukaryotic translational fidelity in the plant kingdom. Our study reveals that the plant-specific CTD plays a significant role in substrate binding and canonical editing function. Through its ability to facilitate protein-protein interactions, we propose the CTD may also provide expanded functional potential for trans-editing enzymes in plants.
