Caesarean Section Scar and Placental Location at the First Trimester of Pregnancy-A Prospective Longitudinal Study.

Background and Objectives: This study aims to report the location of the placenta in the first trimester of pregnancy in groups of women according to the number of previous caesarean deliveries and the visibility of the caesarean scar niche. Materials and Methods: The prospective observational research included adult women aged 18 to 41 years during pregnancy after one or more previous caesarean sections (CSs). Transvaginal (TVS) and transabdominal sonography (TAS) was used to examine the uterine scar and placental location during 11-14 weeks. The CS scar niche ("defect") was bordered in the sagittal plane as a notch at the previous CS scar's site with a depth of 2.0 mm or more. A comparative analysis of the placental location (high or low and anterior or posterior) was performed between groups of women according to the CS number and the CS scar niche. Results: A total of 122 participants were enrolled during the first-trimester screening. The CS scar defect ("niche") was visible in 40.2% of cases. In cases after one previous CS, the placenta was low in the uterine cavity (anterior or posterior) at 77.4%, and after two or more CSs, it was at 67.9%. Comparing the two groups according to the CS scar niche, the placenta was low in 75.5% of cases in the participant group with a CS scar niche and in 75% of cases without a CS scar niche (p = 0.949). Conclusions: The number of previous caesarean deliveries has no effect on the incidence rate of low-lying placentas in the first trimester. Moreover, the presence of the CS scar niche is not associated with anterior low-lying placentas.

Outcomes of low-risk birth care during the Covid-19 pandemic: A cohort study from a tertiary care center in Lithuania.

According to the World Health Organization, midwife-led care is the most appropriate and cost-effective type of perinatal care. As the Covid-19 pandemic with its drastic changes and challenges for the health systems and the medical staff made large adjustments to the healthcare delivery system, midwife-led care became an even more important supportive tool in maintaining unnecessary interventions. This retrospective cohort study aims to compare the outcomes of midwife-led care and team-led care in low-risk births between the Covid-19 pandemic and non-Covid-19 pandemic period. The total studied population was 1,185 singleton births and consisted of 727 births during the non-Covid-19 period and 458 births from the Covid-19 period. The study revealed the safety of low-risk birth care during the first wave of the Covid-19 pandemic in both groups. The maternal and perinatal outcomes remained stable without an increased rate of unsuccessful vaginal births and newborn asphyxia; moreover, birth care of low-risk women provided by midwives preserved autonomy, integrity, and resistance to responding to a disaster. The aforementioned results exhibit that high-quality, safe supervision by midwives in low-risk births can be provided even in high-stress circumstances.

Cesarean Scar Thickness Decreases during Pregnancy: A Prospective Longitudinal Study.

Background and Objectives: The aim of this study is to evaluate changes in uterine scar thickness after previous cesarean delivery longitudinally during pregnancy, and to correlate cesarean section (CS) scar myometrial thickness in the first trimester in two participants groups (CS scar with a niche and CS scar without a niche) with the low uterine segment (LUS) myometrial thickness changes between the second and third trimesters. Materials and Methods: In this prospective longitudinal study, pregnant women aged 18−41 years after at least one previous CS were included. Transvaginal sonography (TVS) was used to examine uterine scars after CS at 11−14 weeks. The CS scar niche ("defect") was defined as an indentation at the site of the CS scar with a depth of at least 2 mm in the sagittal plane. Scar myometrial thickness was measured, and scars were classified subjectively as a scar with a niche (niche group) or without a niche (non-niche group). In the CS scar niche group, RMT (distance from the serosal surface of the uterus to the apex of the niche) was measured and presented as CS scar myometrial thickness in the first trimester. The myometrial thickness at the internal cervical os was measured in the non-niche group. The full LUS and myometrial LUS thickness at 18−20 and 32−35 weeks of gestation were measured in the thinnest part of the scar area using TVS. Friedman's ANOVA test was used to analyse scar thickness during pregnancy and Mann−Whitney test to compare scar changes between CS scar niche and non-niche women groups. For a pairwise comparison in CS scar thickness measurements in the second and third trimesters, we used Wilcoxon Signed Ranks test. Results: A total of 122 eligible participants were recruited to the study during the first trimester of pregnancy. The scar niche was visible in 40.2% of cases. Uterine scar myometrial thickness decreases during pregnancy from 9.9 (IQR, 5.0−12.9) at the first trimester to 2.1 (IQR, 1.7−2.7) at the third trimester of pregnancy in the study population (p = 0.001). The myometrial CS scar thickness in the first trimester (over the niche) was thinner in the women's group with CS scar niche compared with the non-niche group (at internal cervical os) (p < 0.001). The median difference between measurements in the CS scar niche group and non-niche group between the second and third trimester was 2.4 (IQR, 0.8−3.4) and 1.1 (IQR, 0.2−2.6) (p = 0.019), respectively. Myometrial LUS thickness as percentage decreases significantly between the second and third trimester in the CS scar niche group compared to the non-niche group (U = 1225; z = −2.438; p = 0.015). Conclusions: CS scar myometrial thickness changes throughout pregnancy and the appearance of the CS scar niche was associated with a more significant decrease in LUS myometrial thickness between the second and third trimesters.

Lithuania's experience in reducing caesarean sections among nulliparas: the impact of the quality improvement course.

BACKGROUND: To evaluate the role of the quality improvement course (QIC) to reduce the caesarean section (CS) rate among nulliparas (Robson groups 1 and 2) and to find out which group of women have reduced the CS rate following attendance at the course. METHODS: The QIC was organized in 2015. For the evaluation of the CS rate after the OIC, deliveries from the selected hospitals in 2014 and 2016 were compared using MS EXCEL and SPSS 23.0. RESULTS: Nulliparas accounted for 44.6% (3585/8046) and 42.9% (3628/8460) of all the deliveries in 2014 and 2016 years, respectively. The CS rate among nulliparas decreased from 19.0% (665/3502) in 2014 to 16.8% (593/3526) in 2016 (p = 0.018). The greatest decrease in absolute contribution to the overall CS rate was recorded in group 1 (p = 0.08). Perinatal mortality was 3.1 in 2014 and 3.9 in 2016 per 1000 deliveries (p = 0.569). CONCLUSION: The QIC has helped to reduce the CS rate among nulliparas without a negative influence on perinatal mortality. The greatest decrease in the overall CS rate was recorded among nulliparous women who were treated with oxytocin and managed to reach a full cervical dilatation.

Lithuania's experience in reducing caesarean sections among nulliparas.

BACKGROUND: To evaluate the role of the TGCS to reduce the caesarean section (CS) rate among nulliparas (Robson groups 1 and 2) and to find out which group of women have reduced the CS rate by using this tool. METHODS: The Robson classification was introduced in Lithuanian hospitals prospectively classifying all the deliveries in 2012. The CS rate overall and in each Robson group was calculated and the results were discussed. The analysis was repeated in 2014 and the data from the selected hospitals were compared using MS EXCEL and SPSS 23.0. RESULTS: Nulliparas accounted for 43% (3746/8718) and 44.6% (3585/8046) of all the deliveries in 2012 and 2014 years, respectively. The CS rate among nulliparas decreased from 23.9% (866/3626) in 2012 to 19.0% (665/3502) in 2014 (p < 0.001).The greatest decrease in absolute contribution to the overall CS rate was recorded in groups 1 (p = 0.005) and 2B (p < 0.001). Perinatal mortality was 3.5 in 2012 and 3.1 in 2014 per 1000 deliveries (p = 0.764). CONCLUSION: The TGCS can work as an audit intervention that could help to reduce the CS rate without a negative impact on perinatal mortality.

Comparison of midwife-led and obstetrician-led care in Lithuania: A retrospective cohort study.

OBJECTIVE: To compare midwife-led and obstetrician-led care and their relation to caesarean section rates and obstetric and neonatal outcomes in low-risk births. DESIGN: Hospital registry based retrospective cohort study. SETTING: Tertiary-care women's hospital in Kaunas, Lithuania. PARTICIPANTS: A total of 1384 and 1283 low-risk delivering women in 2012 and 2014, respectively. METHODS: The women choose either a midwife as their lead carer (midwife-led group), or an obstetrician-gynaecologist (obstetrician-led group). MAIN OUTCOME MEASURES: The primary outcome was caesarean birth. Secondary outcomes included instrumental vaginal births, amniotomy, augmentation of labour, epidural analgesia, episiotomy, perineal trauma, labour duration, birthweight and Apgar score < 7 at 5 min. RESULTS: The proportion of caesarean births was 4.4% in the midwife-led and 10.7% in the obstetrician-led group (p < 0.001) in 2012, and 5.2% and 11.8% (p < 0.001) in 2014, respectively. Younger maternal age (≤34 years) and midwife-led care was associated with a significantly decreased odds for caesarean section and nulliparity with a significantly increased odds for caesarean birth. Women in the midwife-led group had fewer amniotomies and labour augmentations compared with the obstetrician-led group. Episiotomy, perineal trauma, duration of labour and neonatal outcomes did not differ between the groups. CONCLUSION: Midwife-led care for women with low-risk birth reduced the caesarean section and several medical interventions with no apparent increase in immediate adverse neonatal outcomes compared with obstetrician-led care. IMPLICATIONS FOR PRACTICE: Midwife-led care for low-risk women should be encouraged in countries with health care system where obstetrician-led care births dominates.

Implementation of the Robson classification in clinical practice:Lithuania's experience.

BACKGROUND: To determine the cesarean section (CS) rate in Lithuania, identify the groups of women that influence it using the Robson classification and to determine the impact of implementing the use of the Robson classification on the CS rate. METHODS: The Robson classification was introduced in Lithuanian hospitals prospectively classifying all the deliveries in 2012. The overall CS rate, sizes of the Robson groups of women, CS rate in each group and contribution to the overall CS rate from each group was calculated and the results were discussed. The analysis was repeated in 2014 and the data were compared using MS EXCEL and SPSS 23.0. RESULTS: Nineteen Lithuanian hospitals participated in the study. They represented 84.1% of the deliveries (23,742 out of 28,230) in 2012 and 88.5% of the deliveries (24,653 out of 27,872) in 2014. The CS rate decreased from 26.9% (6379/23,742) in 2012 to 22.7% (5605/24,653) in 2014 (p < 0.001). The greatest contributions to the overall CS rate were made by groups 1, 2 and 5. The greatest decrease in the CS rate was detected in group 2. The absolute contribution to the overall CS rate decreased from 4.9% to 3.8%. CONCLUSION: The Robson classification can work as an audit tool to identify the groups that have the greatest impact on the CS rate. It also helps to develop a strategy focussing on the reduction of the CS rate.

Perceived changes in knowledge and confidence of doctors and midwives after the completion of the Standardized Trainings in Obstetrical Emergencies.

BACKGROUND AND OBJECTIVES: There are only few training programs in obstetric emergencies currently in use and only some of them were evaluated with an adequate sample of participants. Therefore, we present the evaluation of the novel Standardized Trainings in Obstetrical Emergencies (STrObE), conducted in Lithuania. The aim of this study was to analyze whether participants' self-reported knowledge and confidence increased after the trainings, and whether the impact of the trainings was long-lasting. MATERIALS AND METHODS: Data was collected across the majority of hospitals providing secondary and tertiary obstetrical care in Lithuania in 2015. A total of 650 obstetricians-gynecologists and midwives attended the trainings; 388 (response rate 59.7%) of them filled in the initial questionnaire before the trainings, 252 (64.9%) immediately after, 160 (41.2%) 6 weeks after, and 160 (41.2%) 6 months after the trainings, which was the final sample for the analyses. Participants used a Likert-type scale to evaluate their knowledge and confidence about management of urgent obstetrical situations: vacuum-assisted vaginal delivery, shoulder dystocia, postpartum hemorrhage, preeclampsia/eclampsia, early preterm labor, and dystocia. We assessed how participants' self-reported knowledge and confidence changed after the trainings (compared to before the trainings) and how long the effect was retained for. RESULTS: The mean score of self-reported knowledge in obstetrical emergencies increased immediately after the trainings comparing to the scores before the trainings (P<0.001) and it did not differ further between the three time points after the trainings (i.e. immediately, 6 weeks, and 6 months; P>0.05). The same pattern was observed for self-reported confidence scores. The increase in self-reported knowledge and confidence after the trainings was stable. Moreover, the self-reported knowledge and confidence gains were greater for those participants with lower work experience, although benefit was seen across all experience levels. CONCLUSIONS: STrObE improved participants' self-reported knowledge and confidence and lasting positive effects were observed for at least 6 months after the initial trainings. Moreover, the trainings were more beneficial for those with lower work experience, although they benefited all the participants.

The impact of the implementation of the postpartum haemorrhage management guidelines at the first regional perinatal centre in Southern Kazakhstan.

BACKGROUND: Postpartum haemorrhage (PPH) remains one of the most common causes of maternal morbidity and mortality. Therefore, clearly written PPH management guidelines should be used in clinical practice. The aim of this study was to evaluate the effectiveness of the implementation of PPH management guidelines at the First Regional Perinatal Centre of Southern Kazakhstan (FRPC). METHODS: Between 2012 and 2013 an interventional study was performed whereby the PPH management guidelines were implemented at the FRPC. All of the deliveries that were complicated by PPH 8 months before and 8 months after the intervention were analysed. Prevalence and severity of PPH, and the change in prevention, diagnostics and management of PPH was evaluated and statistical analysis using the SPSS 22.0 was performed. RESULTS: There were in total 5404 and 5956 deliveries in the pre- and post-intervention periods, respectively. The rates of PPH and severe PPH decreased from 1.17 to 1.02 % (p = 0.94) and from 0.24 to 0.22 % (p = 0.94), respectively. Blood loss on average increased from 1055 to 1170 ml in the post-intervention period. The pharmacological treatment of postpartum haemorrhage with uterotonics was administered most frequently during both periods. After the implementation of the guidelines, the number of transfused units of packed red blood cells decreased from 4.76 to 2.48 units/case. In addition, the amount of transfused fresh frozen plasma decreased by 20 %. The number of conservative interventions and conservative operations increased from 7.9 to 52.7 % and from 3.9 to 48.6 %, respectively. The number of hysterectomies decreased from 23.7 % in pre-intervention to 8.1 % in the post-intervention period. CONCLUSIONS: The implementation of the PPH management guidelines had a positive effect on PPH prevention, diagnostics and management. It led to a more conservative aproach to the treatment of PPH. Therefore, clearly written PPH management guidelines, adapted for a particular hospital, should be developed and used in clinical practice.

The impact of postpartum haemorrhage management guidelines implemented in clinical practice: a systematic review of the literature.

Postpartum haemorrhage (PPH) is an urgent obstetric condition requiring an immediate response and a multidisciplinary approach. The aim of this study was to review PPH management guidelines implemented in clinical practice, to evaluate their impact regarding prevention, diagnosis and treatment, and to analyze how the numbers of PPH cases changed in the post-intervention period. A systematic search in the PubMed database was performed. The references of all included articles were examined. Studies evaluating the management of PPH and the impact on the numbers of cases of this pathology after the implementation of new or updated guidelines were involved in the analysis. Two reviewers independently examined the titles and abstracts of all identified citations, selected potentially eligible studies, and evaluated their full-text versions. Methodological quality was assessed using a checklist based on the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement. We analyzed seven articles that evaluated the impact of new or updated guidelines for PPH management implemented in clinical practice. In four trials, the numbers of PPH cases declined after the intervention. Guidelines for PPH management can have a positive impact on the reduction of the number of PPH cases.

Prevalence of human papillomavirus types 16, 18, and 45 in women with cervical intraepithelial changes: associations with colposcopic and histological findings.

The aim of the study was to determine the prevalence of human papillomavirus (HPV) types 16, 18, and 45 in women with cervical intraepithelial changes caused by high-risk HPV in relation to colposcopic and histological findings. MATERIAL AND METHODS. A prospective study of 393 women with cervical cytologic changes confirmed by the Papanicolaou test was undertaken from April 3, 2006, to April 3, 2007. The Hybrid Capture 2 assay was performed. HPV-positive women underwent genotyping for types 16, 18, and 45. Colposcopy and biopsy were performed in 317 (80.7%) and 249 women (63.4%), respectively. The results were analyzed by age groups. RESULTS. Of all the women with cervical intraepithelial changes, 59% were positive for HR HPV, and 62% were positive for HPV types 16, 18, and 45. HPV types 16, 18, and 45 were detected in 54.8% of women with ASC-US/AGUS/ASC-H, 50.0% of women with LSIL, and 75.6% of women with HSIL. After confirmation of any histological and colposcopic changes, HPV types 16, 18, and 45 were detected in 68.0% and 69.0% of women, respectively. Moreover, 84.2% of the women with HSIL and high-grade colposcopic changes, and 78.5% of the women with HSIL and CIN 2/CIN 2-3/CIN 3/carcinoma in situ were positive for HPV types 16, 18, and 45. The sensitivity of the Papanicolaou test together with the Hybrid Capture 2 test compared with the Papanicolaou test together with the HPV 16/18/45 test diagnosing CIN 2+ changes did not differ (96.7% vs. 97.1%), but the specificity was higher (40.3% vs. 8.0%). CONCLUSIONS. The majority of the cytologic, colposcopic, and histological changes were caused by HPV types 16, 18, and 45. Despite the high prevalence of HPV types 16, 18, and 45, testing for these genotypes together with the Papanicolaou test did not improve the diagnosis of high-grade cervical intraepithelial lesions.

Prevalence of maternal group B streptococcal colonisation in European countries.

BACKGROUND: Group B streptococcus (GBS) is a leading cause of neonatal sepsis in many industrialised countries. However, the burden of perinatal GBS disease varies between these countries. We undertook a systematic review to determine the prevalence of maternal group B streptococcal colonisation, one of the most important risk factor for early onset neonatal infection, and to examine the serotype distribution of the GBS strains isolated and their susceptibility to antibiotics in European countries. METHODS: We followed the standard methodology for systematic reviews. We prepared a protocol and a form for data extraction that identifies key characteristics on study and reporting quality. The search was conducted for the years 1996-2006 including electronic, hand searching and screening of reference lists. RESULTS: Twenty-one studies presented data on 24,093 women from 13 countries. Among all studies, GBS vaginal colonisation rates ranged from 6.5 to 36%, with one-third of studies reporting rates of 20% or greater. The regional carriage rates were as follows: Eastern Europe 19.7-29.3%, Western Europe 11-21%, Scandinavia 24.3-36%, and Southern Europe 6.5-32%. GBS serotypes III, II and Ia were the most frequently identified serotypes. None of the GBS isolates were resistant to penicillin or ampicillin, whereas 3.8-21.2% showed resistance to erythromycin and 2.7-20% showed resistance to clindamycin. CONCLUSION: Although there is variation in the proportion of women colonised with GBS, the range of colonisation, the serotype distribution and antimicrobial susceptibility reported from European countries appears to be similar to that identified in overseas countries.

Prevalence and risk factors of HPV infection among high-risk rural and urban Lithuanian women.

AIMS: To investigate the prevalence, persistence and risk factors of high oncogenic risk human papillomavirus (HPV) among urban and rural women of reproductive age coming to consult a gynaecologist. METHODS: A prospective cohort study in urban (Kaunas) and rural (Marijampole) regions of Lithuania. The data were collected in 8 healthcare institutions from women seeking consultation of gynaecologists using a questionnaire for finding out demographic, social, behavioural and biomedical factors. HPV DNA was determined by molecular hybridization method (hybrid capture version II) determining HPV of high oncogenic risk. RESULT: 1,120 women participated in the study. The prevalence of high-risk HPV among the studied women was 25.1%. It was higher among the urban women than among the rural women. The prevalence of high-risk HPV was increased if the subjects had 2 or more sexual partners during the last 12 months (OR 2.81; 95% CI 1.83-4.32), were 19 years of age or younger (OR 2.68; 95% CI 1.47-4.91), were smoking (OR 1.81; 95% CI 1.16-2.81), and had secondary or lower education level (OR 1.43; 95% CI 1.01-2.04). This infection was obviously associated with high- and low-grade squamous intraepithelial changes of the cervix (OR 1.66, 95% CI = 1.08-2.53). CONCLUSION: The incidence rate for cervical cancer in Lithuania is one of the highest in comparison with other European countries. HPV infection was also particularly common in the studied population. About one-fourth of the women were infected with high-risk HPV infection. Young and less educated women were found to be the group that was most exposed to HPV, and therefore public health interventions and education seem to be essential in programs aimed at reducing the incidence of cervical cancer.
