Role of sVEGFR1 in the development of complications in pregnant women with antenatal fetal death anamnesis record
Bibliographic record
Abstract
Background sVEGFR1 is a hypoxia influenced growth factor, involved in the endothelial dysfunction characterizing the pregnancy disorder of preeclampsia. Objective Determine correlation between dynamic pattern of sVEGFR1 serum concentration and complications in pregnant women with antenatal fetal death history for timely diagnosis. Materials and Methods A total of 35 women in the second and third trimester of pregnancy were enrolled in the study group and 30 women in the control group. The study group was divided into 3 subgroups: subgroup #1: pregnant women, with no placental insufficiency (n=21), subgroup #2 - pregnant women with PI (n=8), subgroup #3 - pregnant women with PI resulting in preeclampsia(n=6). The control group comprised 30 pregnant women with uncomplicated childbirth. sVEGFR1 concentration was estimated in maternal serum by means of enzyme multiplied immune assay Quantikine (R and D systems, USA and Canada). Statistical data was assessed by SPSS statistics. Package was used to perform all the statistical analysis. The conventional p0,05 was used to assess statistical significance. Results Average age of women in the study group was 28,44,7 years, in the control group 27,74,7 years. A physiological sVEGFR1 serum concentration was observed in the subgroup #1. As well as that, this group demonstrated concordant to the healthy pregnant women fluctuations of sVEGRF1 serum concentration. However, sVEGRF1 level was 1,2 fold less than in the control group during 29-32, 33-36 weeks of pregnancy. It was statistically proven, that fluctuations in sVEGRF1 serum concentration in the subgroup #2 were similar to the ones in the control group. No statistically significant changes of sVEGRF1 serum concentration compared to the control group were detected in the subgroup #3 up to the 28th week of pregnancy. However, a 1,5 fold increase of sVEGFR1 concentration was observed in the subgroup #3 (p<0,005) in comparison with the control group (1586358 pg/ml, 2347519 pg/ml, 36951547 pg/ml during 29-32, 33-36, >37 weeks of pregnancy, respectively). Control group demonstrated physiological concentration of sVEGRF1 throughout the pregnancy. Conclusion Changes in sVEGFR1 serum concentration were statistically significant in the group of pregnant women with PI, resulting in preeclampsia. Moreover, they were detected 3-4 weeks prior to clinical symptoms, providing opportunity for timely diagnosis and prevention measures.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
