Genetic variation in the maternal vitamin D receptor FokI gene as a risk factor for recurrent pregnancy loss.

PURPOSE: Recurrent pregnancy loss (RPL) is a reproductive disorder defined as the loss of two or more pregnancies before 24 weeks of gestation. Despite the fact that several mechanisms have been previously described for the pathogenesis of RPL, the causes of ∼50% of cases remain unknown. However, recent studies indicate association of vitamin D deficiency with adverse pregnancy outcome, including RPL. The vitamin D receptor (VDR) is a crucial mediator of the pleiotropic cellular effects of vitamin D. Its function is influenced by several single nucleotide polymorphisms (SNPs). The main objective of this study is to assess whether maternal VDR SNPs are associated with the risk of RPL in Slovenian and Croatian women. METHODS: A case-control study including 320 women with RPL and control women is designed to examine the potential association of VDR polymorphisms (FokI rs222857, Cdx2 rs11568820, and Taq1 rs731236) with RPL. Genotyping is performed using polymerase chain reaction and restriction fragment length polymorphism methods. RESULTS: We find a statistically significant higher frequency of the rs222857 CC genotype (χ2 = 6.61, p = .036) and C allele (χ2 = 5.93, p = .015) in RPL women compared to controls. Subsequently, the odds for RPL for the rs222857 are increased under the recessive (CCvsCT + TT: OR = 1.78; 95% CI = 1.12-2.82; p = .015) and the codominant (CCvsTT: OR = 2.21; 95% CI = 1.08-4.53; p = .029; CCvsCT: OR = 1.68; 95% CI = 1.04-2.72; p = .036) genetic models. The other two analyzed polymorphisms did not show any statistical significant result. CONCLUSIONS: Our results suggest that variations in the maternal VDR FokI gene might be associated with RPL in Slovenian and Croatian women.

Obtaining the child testimony in the criminal proceedings.

Children fall under the special category of vulnerable witnesses. Children's vulnerability is the reason that we must approach obtaining the child's testimony in the criminal proceedings with special attention. It is important to take the child's testimony as soon as possible and to avoid the repetition of interrogation. The criminal proceedings law and the juvenile court law enable children interrogation through the professional person without the presence of other parties in the procedure and enable the recording of such interrogation by audio-video link which considerably diminish the secondary victimization. The professionals who obtain the testimony must be well acquainted with children's psychological development. Knowledge of psychological development is of major importance in order to make the quality arrangements for interrogation and to interrogate the child and to achieve positive social contact between the examiner and the examinee and it is also of great importance for the credibility evaluation of the child's testimony. The adequate way of children interrogation will enable the child to say the correct information and to recognize the perpetrator. The forensic interview is well elaborated and child adapted technique of interrogation. Respecting the rules of forensic interview will enable the child's testimony on court to be relevant evidence.
