Objective This study investigated the relationship between umbilical vein diameter and cord length and fetal outcome in low-risk pregnancies (fetuses appropriate for gestational age [AGA]). Methods A prospective cohort study of 39 singleton pregnant women aged 19–44 years at between 38+0 and 41+6 weeks of gestation was conducted. Case demographics, umbilical vein diameter measured by prenatal ultrasound, postnatal birth weight, gender, 1- and 5-minute Apgar scores, blood gas analysis, and umbilical cord length were recorded. Fetuses with a fetal weight in the 10–90th percentile according to week of gestation were accepted as AGA. Results The mean age of the pregnant women was 27.5±5.3 years. 33% (13/39) of the pregnant women were nulliparous. There was no statistically significant correlation between umbilical vein diameter and other variables in correlation analysis (p>0.050). Umbilical cord length and umbilical vein lactate level were found to have a statistically negative and significant correlation (r=-0.418; p=0.015); however, no other pregnancy outcomes were found to have a significant correlation. There was no statistically significant difference between the median values of umbilical vein diameter and cord length by gender (p=0.076 and 0.181, respectively). Conclusion In conclusion, this study found no relationship between umbilical vein diameter and cord length and fetal weight and pregnancy outcome in low-risk 38.0–41.6-week pregnancies (AGA fetuses). However, the obtained results still need to be confirmed by larger series.

Cervical cancer has a significant place worldwide in terms of cancer-related deaths in women. In the development of cervical cancer and its precursor, cervical intraepithelial neoplasia (CIN), the most important reason is high-risk human papillomavirus (HR-HPV) persistence. 1 Factors such as smoking, high-parity, long-term use of oral contraceptives, other sexually transmitted infectious agents and coinfestation are thought to affect the progression to cervical cancer in HPV infected women. 2,3 The genital mycoplasmas are a class of pathogenic, the smallest free living bacteria in the ciliated epithelial cells of the urinary and genital tract of humans. 4 The genital mycoplasmas colonized in the genital system consist of six types, including Ureaplasma urealyticum, Ureaplasma parvum, Mycoplasma hominis, Mycoplasma genitalium, Mycoplasma primatum and Mycoplasma spermatophilum. 5 Some studies have shown that the rate of infection of U. urealyticum is high in HPV positive women. 6 Similarly, there are
