Background: Indications of dialysis treatment for patients with end-stage renal disease depend on various clinical and laboratory parameters. In this study, we aimed to determine whether standardized serum cystatin C (SCC) equation may be an applicability of marker for dialysis initiation and its relationship to other clearance values among patients with advanced chronic kidney disease.
Materials And Methods: A total of 84 patients (45 males, 39 females) aged 19-89 were evaluated in this study. Hemodialysis was indicated according to clinical and laboratory findings, and estimated glomerular filtration rate (eGFR) was according to four different formulas [MDRD, EpiCKD, Cockcroft Gault formula (CGF) and SCC equation].
Results: eGFR values of patients in the study were 7.23 ± 3.26, 7.86 ± 3.78, 15.09 ± 10.88 and 11.31 ± 4.54 according to MDRD, EpiCKD, SCC equation and CGF, respectively. There was a positive correlation between MDRD, EpiCKD and CGF, and between EpiCKD and CGF (p < 0.01). Also, statistically significant correlation was found between SCC equation and CGF (p < 0.05).
Conclusion: SCC equation was not seemed to be an appropriate marker for starting dialysis in patients with advanced CKD.

Direct and indirect effects of childhood adversity on psychopathology: Investigating parallel mediation via self-concept clarity, self-esteem and intolerance of uncertainty.
Br J Clin Psychol

School of Psychology, College of Health and Life Sciences, Aston University, Birmingham, UK.
Objectives: The aim was to extend previous work on the identity disruption model (IDM) of adult psychological distress. According to the IDM, aversive childhood experiences (ACEs) disrupt the development of identity, resulting in an unclear sense of self and a reliance on external sources of self-definition, leading to psychological distress in adulthood. In line with this model, self-concept clarity (SCC) in parallel with self-esteem (SE) and intolerance of uncertainty (IU) has been shown to mediate the relationship between childhood adversity and depression and anxiety.

The utilization of Self-compacting Concrete (SCC) has escalated worldwide due to its superior properties in comparison to normal concrete such as compaction without vibration, increased flowability and segregation resistance. Various other desirable properties like ductile behaviour, increased strain capacity and tensile strength etc. can be imparted to SCC by incorporation of fibres.

Background: Milk somatic cell count (SCC) is an international standard for identifying mastitis in dairy cows and measuring raw milk quality. Milk SCC can be predicted based on dielectric relaxation parameters (DRPs). We noted a high correlation between DRPs and the milk composition content (MCC), and so we hypothesized that combining DRPs with MCC could improve the prediction accuracy of milk SCC.

Considering the long-term memory and volatility clustering of the European Union (EU) Carbon Emission Allowances (EUA) futures returns, based on the economy-energy-environment system perspective and the assumption of investors' heterogeneity, this study proposes a joint modeling approach combining the fractionally integrated generalized autoregressive conditional heteroscedasticity model (FIGARCH) and the stochastic cusp catastrophe model (SCC) to examine the equilibrium bifurcations and extreme risks in the EU carbon futures market. The relevant results are threefold. (1) The SCC model has good fitting effect and interpretability, and is an effective method for investigating catastrophe reactions under time-varying volatility conditions.

The use of hybrid fibre-reinforced Self-compacting concrete (HFR-SCC) has escalated recently due to its significant advantages in contrast to normal concrete such as increased ductility, crack resistance, and eliminating the need for compaction etc. The process of determining residual strength properties of HFR-SCC after a fire event requires rigorous experimental work and extensive resources. Thus, this study presents a novel approach to develop equations for reliable prediction of compressive strength (cs) and flexural strength (fs) of HFR-SCC using gene expression programming (GEP) algorithm.
