Effects of upper-body resistance exercise training on serum nesfatin-1 level,insulin resistance,and body composition in obese paraplegic men

Background

As a recently discovered adipokine, nesfatin-1 is conducive to insulin sensitivity, lipid profile, energy balance, and probably obesity.

Retracted: Icariin inhibits proliferation,migration, and invasion of medulloblastoma DAOY cells by regulation of SPARC

Icariin (ICA) is obtained from Epimedium brevicornu maxim and exploited to remedy miscellaneous cancers. But the role of ICA in medulloblastoma remains hazy. The research delved into the antitumor activity of ICA in medulloblastoma DAOY cells. ICA with diverse concentrations was utilized to stimulate DAOY cells, and the biological functions of ICA in medulloblastoma DAOY cells were examined. Then, the relative SPARC expression was determined in ICA‐managed DAOY cells, and the pc‐SPARC vector was transfected into DAOY cells to further probe the influence of SPARC and JAK1/STAT3 and PI3K/AKT pathways in ICA‐managed DAOY cells. A xenograft model was established to investigate the function of ICA in vivo. ICA restrained cell viability, expedited apoptosis, prohibited cell migration and invasion, and meanwhile affected the associative factors expression in DAOY cells. Additionally, SPARC expression was declined in ICA‐stimulated DAOY cells. Overexpressed SPARC reversed the functions of ICA in above‐involved cell behaviors of DAYO cells and the correlative protein levels. Besides, ICA notably frustrated JAK1/STAT3 and PI3K/AKT activations in DAOY cells. Beyond that, ICA prohibited tumor formation in vivo. The results concluded that ICA exhibited the antitumor activity in DAOY cells via decreasing SPARC and inactivating JAK1/STAT3 and PI3K/AKT pathways.

Association between first oral examination characteristics and dental treatment needs in privately insured children: A claims data analysis

BackgroundEarly childhood caries (ECC) remains the most common, preventable infectious disease among children in the United States. Screening is recommended after the eruption of the first tooth, but it is unclear how the age at first dental examination is associated with eventual restorative treatment needs. The authors of this study sought to determine how provider type and age at first dental examination are associated longitudinally with caries experience among children in the United States.MethodsDeidentified claims data were included for 706,636 privately insured children aged 0 through 6 years as part of the nationwide IBM Watson Health Market Scan (2012-2017). The authors used Kaplan-Meier survival analysis to describe the association between the age of first visit and restorative treatment needs.ResultsA total of 21% of this population required restorative treatment, and the average age at first dental examination was 3.6 years. A multivariable Cox proportional hazards model showed increased hazard for restorative treatment with age at first dental visit at 3 years (hazard ratio, 2.05; 95% CI, 1.97 to 2.13) and 4 years (hazard ratio, 3.99; 95% CI, 3.84 to 4.16).ConclusionThe high proportion of children requiring restorative treatment and late age at first dental screening show needed investments in educating general dentists, medical students, and pediatricians about oral health guidelines for pediatric patients.Practical ImplicationsCommunicating the importance of children establishing a dental home by age 1 year to parents and health care professionals may help reduce disease burden in children younger than 6 years.

A lethal and rare cause of arthrogryposis: Glyt1 encephalopathy

Glycine encephalopathy with normal serum glycine (MIM #617301), also known as GLYT1 encephalopathy, is an extremely rare disorder caused by biallelic variants in SLC6A9 and characterised by facial dysmorphic features, skeletal findings including contractures, knee hyperextension, and joint dislocations and seizures. To date, only ten patients from five families have been reported and only two of them could survive until childhood. In this study, we report on a consanguineous Turkish couple with a history of six pregnancies with three habitual abortions and three postpartum exitus. While in three pregnancies the babies were born prematurely at 32nd gestational week by emergency ceserean section due to hydrops and fetal distress, the other pregnancy was medically terminated at 16th gestational week due to absent fetal heart activity. The product of all these three pregnancies exhibited similar phenotype including short neck, thoracic kyphosis, hypertrichosis, joint contractures and dislocations, hypertonia, knee hyperextension and facial dysmorphic features. Trio exome sequencing was performed prenatally during the last pregnancy and a novel VUS variant in SLC6A9 and a likely pathogenic variant in MTOR gene were detected. DNA isolation was performed from frozen muscle and adrenal tissue of previously autopsied fetuses with similar clinical features, and the same variants were confirmed in both of them. Our data suggest that SLC6A9 and MTOR variants may be responsible for this extremely lethal phenotype in this family.
