Background/aim: To evaluate the prevalence of tetanus vaccination in pregnant women and determine the factors affecting the vaccination and barriers to vaccination. Materials and methods: An observational-descriptive study was conducted on 494 women who gave birth at the Etlik Zübeyde Hanım Women's Health Training and Research Hospital, Ankara, Turkey. Participants were divided into 2 groups, vaccinated and unvaccinated. Sociodemographic characteristics, obstetric history, and prenatal care status were compared between the 2 groups. Results: There were 242 (48.9%) and 252 (51.1%) women in the vaccinated and unvaccinated groups, respectively. The vaccination rate decreased as the number of pregnancies increased (P = 0.009). As the level of income increased, there was a statistically significant increase in the vaccination rate (P = 0.048). The status of education and having an occupation did not affect the vaccination rate (P > 0.05). The vaccination rate was higher in women with regular follow-ups when compared to those who did not get a regular follow-up (76.5% vs. 38.7%) (P = 0.001). The vaccination rate was significantly higher in women who had knowledge about tetanus vaccine during pregnancy (P < 0.005). Conclusions: All pregnant women should be encouraged to get regular antenatal care to increase vaccination rates. Health care providers should give all pregnant women detailed information about the safety, effectivity, and benefits of vaccines. [ABSTRACT FROM AUTHOR]

Objective: To evaluate perinatal outcomes in human immunodeficiency virus (HIV) infected pregnant women in Turkey. Material and Methods: Maternal characteristics, pregnancy complications, laboratory findings including HIV load, CD4 cell count, CD4/CD8 ratio, neonatal features and final HIV status of the baby were retrospectively analyzed. Results: The sample included 26 singleton pregnancies, from 25 HIV-infected women. The ethnicities were Turkish (n=18), East European (n=4), Asian (n=2) and African (n=2). The majority (76.9%) was aware of their HIV status before becoming pregnant. Four cases (15.3%) were diagnosed during pregnancy and two (7.8%) at the onset of labor. The results for median HIV viral load, CD4 count, and CD4/CD8 ratio at birth were 20 copies/mL (0-34 587), 577/mm³ (115-977), and 0.7 (0.1-1.9), respectively. The HIV viral load rate was 5.5% in eighteen women taking anti-retroviral treatment. The rates of gestational diabetes mellitus, gestational hypertension, intrauterine growth restriction, and preterm delivery were 3.8%, 3.8%, 7.6%, and 8% (numbers are 1;1;2;2), respectively. The mean gestational week at birth was 38 weeks and mean birthweight is 2972±329 g. Two babies were congenitally infected with HIV (infection rate of 8.3%). There was one needle-related accident during surgery. Conclusion: Timely diagnosis of HIV infection during pregnancy is important for preventing mother to child transmission. HIV infected women may give birth to HIV negative babies with the help of a multidisciplinary team, composed of perinatology, infectious diseases, and pediatrics specialists. [ABSTRACT FROM AUTHOR]

Objectives: To examine the costs and outcomes of different screening strategies for Down Syndrome (DS) in singleton pregnancies.Study Design: A decision-analytic model was developed to compare the costs and the outcomes of different prenatal screening strategies. Five strategies were compared for women under 35-year of age: 1A) triple test (TT), 2A); combined test (CT), 3A) Non-invasive Prenatal Screening Test by using cell free fetal DNA (NIPT), 4A) and 5A) NIPT as a second-step screening for high-risk patients detected by either TT, or CT respectively. For women ≥35-year of age, 1B) implementing invasive test (amniocentesis -AC) and 2B) NIPT for all women were compared. Data was analyzed to obtain the outcomes, total costs, the cost per women and the incremental cost-effectiveness ratios (ICERs) for screening strategies.Results: Among the current strategies for women under 35 years old, CT is clearly dominated to TT, as it is more effective and less costly. Although, the current routine practice (2A) is the least-costly strategy, implementing NIPT as a second step screening to high-risk women identified by CT (5A) would be more effective than 2A; leading to a 10.2% increase in the number of detected DS cases and a 96.3% reduction in procedural related losses (PRL). However, its cost to the Social Security Institution that is a public entity would be 17 times higher and increase screening costs by 1.5 times. Strategy 5A would result in an incremental cost effectiveness of 6,873,082 (PPP) US$ when compared to the current one (2A). Strategy 1B-for offering AC to all women ≥35-year of age is dominated over NIPT (2B), as it would detect more DS cases and would be less costly. On the other hand, there would be 206 PRL associated with AC, but NIPT provides clear clinical benefits as there would be no PRL with NIPT.Conclusions: NIPT leads to very high costs despite its high effectiveness in terms of detecting DS cases and avoiding PRL. The cost of NIPT should be decreased, otherwise, only individuals who can afford to pay from out-of-pocket could benefit. We believe that reliable cost-effective prenatal screening policies are essential in countries with low and smiddle income and high birth rates as well. [ABSTRACT FROM AUTHOR]

Objective: To evaluate second trimester fetal nasal length measurement results in healthy singleton pregnancies in Turkey. Material and Methods: We analyzed the nasal bone lengths within 19-24 weeks in 661 pregnancies in our hospital. All pregnant women with a single healthy fetus who applied to our perinatology outpatient clinic for detailed obstetric ultrasonography were included in the study. All measurements were performed by the same clinician during routine mid-trimester ultrasound scan. Only the patients who were considered healthy by the examining pediatrician were included in the study. The parents of all fetuses are of Turkish ethnicity. Pearson correlation, regression analysis and P value were calculated between gestational week and nasal bone length. Results: Mean nasal length measurement was 6,21 ± 0,08; 6,66 ± 0,05; 6,88 ±0,05; 7,13 ± 0,08; 7,77 ± 0,11 and 8,33 ± 0,25 mm from 19 to 24 week of pregnancy, respectively. A significant positive correlation was observed between gestational week and nasal bone length. Normal values of nasal bone length measuremens are identified for each gestational weeks acoording to our data and previous 5 studies. Conclusion: In this study, we presented the data of our own center and the results obtained from other studies conducted in our country show significant differences. We are of the opinion that studies conducted by different researchers in different regions remain insufficient to reflect the nomogram of Turkish ethnic origin. For this purpose, multicenter studies are needed to cover the whole society. [ABSTRACT FROM AUTHOR]
