Analysis OF C677T polymorphism in methylene tetrahydrofolate reductase (MTHFR) gene as a risk factor for congenital talipes equino varus (CTEV)

Investigating the association between vitamin D dietary intake during pregnancy and incidence of clubfoot in neonates

AIMS

Talipes equinovarus (clubfoot) is a congenital lower foot deformity that results from a neuromuscular deficiency, but the precise etiology remains elusive. Vitamin D is important for fetal neuromuscular development. In this study, we investigated the association between dietary vitamin D intake during pregnancy and incidence of clubfoot in neonates, since such a question has thus far been overlooked.

METHODS

We conducted a secondary analysis of data collected in the United States, between 2007 and 2011 for a case-control study of children born with clubfoot. Participating mothers were interviewed by telephone about dietary and other health and life-style indicators. Exposure to vitamin D was recorded as the average daily intake of dietary vitamin D over a period of 6 months before pregnancy began. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression.

RESULTS

The dataset included 2667 study participants, of which 663 were cases. Logistic regression showed no significant association between dietary vitamin D or log10 (Vitamin D) intake during pregnancy and incidence of clubfoot in neonates (OR = 1.00, CI = 1.00-1.00, OR = 1.51, CI = 0.83-2.82, respectively). No interaction in the regression model was found between vitamin D and other predictor variables. Results were not confounded by supplement intake of vitamin D during pregnancy.

CONCLUSIONS

Results show no evidence of an association between dietary vitamin D intake and incidence of clubfoot in neonates. The lack of association is not confounded by consumption of vitamin D supplements during pregnancy.

Assessment of the COL9A1 Single Nucleotide Polymorphism with Severity of clubfoot in a paediatric population along with their biological mothers

Background

A frequent birth abnormality known as congenital talipes equinovarus (CTEV) results in severe abnormalities of one or both feet. The risk of CTEV has been shown to be significantly influenced by genetics. It is a typical congenital malformation. Diseases involving the articular cartilage and COL9A1 polymorphisms are linked.

Materials and method

This case parent dyad research was conducted in a premier care medical and educational facility by the Departments of Paediatric Orthopedics and Biochemistry. Children who had been diagnosed with clubfoot as well as their biological mothers took part in the study. 125 kids were able to join in the research when all the screening, inclusion, and exclusion criteria were met. Baseline demographic information was collected, including the child's age and sex, the kind of clubfoot, any family members who have the condition, and whether or not the mothers smoke or drink. Pirani score is used to clinically evaluate every case. Only one peripheral blood sample was taken from each patient, including their Biological Mothers.

Results

out of 125 children enrolled with biological mothers, Col9A1 SNP rs1135056 is substantially related.

Conclusion

Additionally, patients with the GG genotype for rs592121 have a higher chance of developing CTEV than those with other genotypes. In this investigation, we found possible associations between COL9A1 gene polymorphisms in the mother and offspring with the risk of CTEV. Our research may help us comprehend the genetic makeup of CTEV better and lay the groundwork for creative intervention strategies.

Retrospective Case Analysis of 104 Cases of Talipes Equinus

A retrospective study of 104 patients (81 male and 23 females, the age range from 2 to 288days) with talipes equinus was conducted to explore the case factors associated with it. We analyzed and discussed the correlation of plaster correction times, age of first visit, gender, and birthplace of patients in the department and understood their correlation and causality. The data were analyzed using frequency analysis, normality test, chi-square goodness-of-fit test, chi-square test, and PLS regression. The findings are set out below. All the distributions of the number of plaster casts in the samples did not have normality. Therefore, we used the nonparametric test and partial least squares regression (PLS regression) and found that the number of plaster casts was more closely related to the age at first visit, gender, and birthplace and had a strong positive correlation. There was a negative correlation between the times of plaster correction and the compliance of braces. The lower the compliance of patients with braces, the more times the plaster correction will be conducted.
