Objective Pregnancy-associated plasma protein-A2 (PAPP-A2) is a metalloproteinase that cleaves IGFBP-3 and IGFBP-5. Human mutations in PAPPA2 result in short stature with a low percentage of free IGF-I. Little is known about PAPP-A2 levels and the regulation of free IGF-I throughout childhood. We examined PAPP-A2 and intact IGFBP-3 levels in childhood and explored associations between PAPP-A2, free and total IGF-I, and total and intact IGFBP-3 and their relationship to the percentage of free to total IGF-I and anthropometric factors. Design Cross-sectional study at a single center. Methods PAPP-A2, free IGF-I, and intact IGFBP-3 levels were measured in childhood (3–18 years old) and an evaluation of the relationship between these proteins and anthropometric factors. Results In 838 children, PAPP-A2 consistently decreased throughout childhood. In contrast, free IGF-I increased. A pubertal peak in free IGF-I was present in females but was less evident in males. Intact and total IGFBP-3 increased throughout childhood; however, intact IGFBP-3 had a more marked rise than total IGFBP-3. Percent free IGF-I decreased with no distinct pubertal peak. PAPP-A2 levels positively correlated with the percent free IGF-I (Male, Female; r = 0.18, 0.38; P < 0.001) and negatively with intact IGFBP-3 (Male, Female; r = −0.58, −0.65; P < 0.0001). Conclusions This is the first study to describe serum PAPP-A2 and intact IGFBP-3 in children between 3 and 18 years of age. Our correlative findings suggest that PAPP-A2 is an important regulator of the percent free IGF-I which can be a marker of perturbations in the GH/IGF-I axis.

The objective of this study was to investigate the relationship between serum levels of OPG, TGF-β1, and TGF-β2 and BMD decrease rate (BDR) in native Chinese women. This cross-sectional study was performed on 465 healthy native Chinese women aged 35–80 years. Serum levels of OPG, TGF-β1, and TGF-β2 were determined. BDR was measured by DXA at the posteroanterior spine, hip, and distal forearm. At all skeletal sites tested, there was a negative correlation between BDR and serum levels of both OPG (r=−0.122to –0.230, allP= 0.007–0.000) and TGF-β2 (r=−0.100to –0.173, allP= 0.029–0.000) and a positive correlation between BDR and serum TGF-β1 (r=0.245−0.365, allP=0.000). After adjustment for age and BMI, there were no statistically significant correlations between serum levels of OPG or TGF-β2 and BDR. However, statistically significant correlations between serum TGF-β1 and BDR at the lumbar spine and ultradistal forearm remained. Multiple linear regression stepwise analysis showed that serum OPG could explain 1.4–3.7% of BDR variation. Serum TGF-β1 was a positive determinant of BDR and could explain 5.3–13.3% of BDR variation.

Abstract Introduction: Many studies have reported the role of vitamin D in rheumatoid arthritis (RA) which is related to several serum autoantibodies such as RF and Anti CCP. It also has been shown that vitamin D deficiency affect the DAS28 and VAS score inversely. Therefore, we aim to assess the relationship between vitamin D deficiency and RA-related autoantibodies including Anti CCP and RF levels and also evaluate the association between these parameters and the severity of disease.Methods: In this cross-sectional study, RA patients over 16 years of age were enrolled. The severity of diseases was assessed via the DAS28 scoring system. Serum levels of 25(OH) vitamin D were determined by the ELISA method, along with other rheumatoid related laboratory evaluations including Anti CCP, RF and CRPResults: A total of 100 patients with a mean age of 45.27± 14.14 were included and evaluated; of them, 75% were female and 77% lived in the city. Most of the patients (66%) had moderate DAS28 levels; however, no substantial relationship was observed between DAS28 and vitamin D levels. A significant positive relation between serum 25(OH)D level and disease duration, as well as the level of education, was observed. There was also no significant correlation between RA-related autoantibodies and inflammatory serum marker with 25(OH)D.Conclusion: Due to vitamin deficiency in the majority of cases (73%) and the relationship between serum 25(OH)D levels and the duration of disease, it can be concluded that vitamin D levels should be checked in those patients.

BACKGROUND: Although previous studies have separately revealed that parameters such as anxiety, depression, and secondary traumatic stress (STS) are associated with burnout, there is still a limited understanding of the relationship between anxiety, depression, and STS and burnout in intensive care unit (ICU) nurses. AIMS: To investigate the relationship between levels of burnout, anxiety, depression, and STS in ICU nurses. METHOD: A cross-sectional study was conducted with ICU nurses ( N = 164) from a university hospital in eastern Turkey. The participants completed the anxiety, depression, STS, and burnout scales along with the descriptive characteristics form. The data were analyzed using descriptive statistics, correlation, and logistic regression analysis. RESULTS: The mean scores for STS, anxiety, depression, and burnout were 40.60 ± 13.77, 17.14 ± 12.90, 13.28 ± 9.75 and 41.39 ± 14.87, respectively. The results showed that, in the ICU nurses, anxiety, depression, and STS components explained 61% of emotional exhaustion, 38% of depersonalization, and 13% of personal accomplishment. CONCLUSIONS: While the present findings supported the paradigm that burnout in ICU nurses is associated with STS, anxiety, and depression, they also revealed some details about the psychopathological factors associated with burnout. These details were as follows: (1) individuals who resorted to avoidance as a component of STS on a high level were more likely to experience emotional exhaustion and depersonalization, (2) individuals with severe depressive symptoms were more likely to experience a decrease in their personal accomplishment, and (3) individuals with anxiety symptoms were more likely to experience both emotional exhaustion and personal accomplishment.
