Impact of Intraoperative Factors on the Development of Postpartum Septic Complications.

Background and Objectives: Triclosan-coated sutures (antibacterial sutures) can reduce the risk of postoperative surgical site infection. This study aimed to investigate the effect of intraoperative factors, including antibacterial sutures, on the risk of postpartum septic complications. Materials and Methods: The prospective study included patients who underwent caesarean section. The exclusion criterion was chorioamnionitis. The investigation group patient's (n = 67) uterus and fascial sheath of the abdominal wall were sutured with triclosan-coated polyglactin 910 sutures during surgery. The control group consisted of 98 patients using uncoated polyglactin 910 sutures only. The patients were contacted by phone after the 30th postoperative day. Results: No significant difference was found between the investigation group and the control group in the development of postpartum endometritis (11.7% in the investigation group vs. 8.4% in the control group, p = 0.401), wound infection (6.3% vs. 3.6%, p = 0.444) or patients experienced any septic complication (15.9% vs. 12%, p = 0.506). Postpartum endometritis was more common in patients who underwent instrumental uterine examination during the surgery (23.8% vs. 18%, p = 0.043). A moderately strong correlation was found for haemoglobin level on the third-fourth postoperative day with the development of postpartum septic complications, p < 0.001, Pearson coefficient -0.319. Post-caesarean delivery septic complications were not statistically more common in patients with blood loss greater than 1 L. The incidence of post-caesarean endometritis was 13.4%, and wound infection was 4.8% in this study's hospital, having five to six thousand deliveries per year. Conclusions: Using antibacterial sutures during caesarean section does not affect the incidence of postpartum septic complications. Instrumental uterine examination during caesarean section increases the risk of post-caesarean endometritis and is, therefore, not recommended. Haemoglobin level on the 3rd-4th postoperative day, rather than the estimated blood loss during surgery, affects the development of postpartum septic complications.

Management of Pregnancy with Cervical Shortening: Real-Life Clinical Challenges.

Background and Objectives: Preterm birth is the leading cause of neonatal mortality worldwide and may be responsible for lifelong morbidities in the survivors. Cervical shortening is one of the common pathways to preterm birth associated with its own diagnostic and management challenges. The preventive modalities that have been tested include progesterone supplementation and cervical cerclage and pessaries. The study aimed to assess the management strategies and outcomes in a group of patients with a short cervix during pregnancy or cervical insufficiency. Materials and Methods: Seventy patients from the Riga Maternity Hospital in Riga, Latvia, were included in the prospective longitudinal cohort study between 2017 and 2021. Patients were treated with progesterone, cerclage, and/or pessaries. The signs of intra-amniotic infection/inflammation were assessed, and antibacterial therapy was given when the signs were positive. Results: The rates of PTB were 43.6% (n = 17), 45.5% (n = 5), 61.1% (n = 11), and 50.0% (n = 1) in progesterone only, cerclage, pessary, and cerclage plus pesssary groups, respectively. The progesterone therapy was associated with a reduced preterm birth risk (x2(1) = 6.937, p = 0.008)), whereas positive signs of intra-amniotic infection/inflammation significantly predicted the risk of preterm birth (p = 0.005, OR = 3.82, 95% [CI 1.31-11.11]). Conclusions: A short cervix and bulging membranes, both indicators of intra-amniotic infection/inflammation, are the key risk factors in preterm birth risk predictions. Progesterone supplementation should remain at the forefront of preterm birth prevention. Among patients with a short cervix and especially complex anamnesis, the preterm rates remain high. The successful management of patients with cervical shortening lies between the consensus-based approach for screening, follow-up, and treatment on the one side and personalising medical therapy on the other.

Iron Status in Pregnant Women in Latvia: An Epidemiological, Cross-Sectional, Multicenter Study According to WHO and UK Criteria.

Background and Objectives: During pregnancy, iron deficiency anaemia is a common problem associated with health risks for both the mother and her foetus/infant. This study aimed to investigate the prevalence of iron deficiency, iron deficiency anaemia, and related dietary patterns in pregnant women in Latvia. Materials and Methods: This cross-sectional, multicentre study included pregnancy data from 974 women. The sample selection was based on the stratification principle (population of women of childbearing age in regions of Latvia). Maternal demographic details, anthropometric measurements, iron status, dietary patterns, and supplementation information were obtained from maternal files and during interviews held in eight outpatient departments of medical institutions and maternity departments. The prevalence was assessed. Chi-square tests and logistic regression were used to identify associations between iron deficiency and sociodemographic characteristics, dietary patterns, and iron supplement intake during pregnancy. The criterion used for the diagnosis of iron deficiency anaemia is a Hb level <110 g/L in the 1st and 3rd trimesters and <105 g/L during the 2nd trimester as recommended by the WHO. However, the UK guideline was used for borderline iron deficiency, which is an SF level <30 µg/L in all trimesters. Results: The observed prevalence of anaemia was 2.8% in the first trimester, 7.9% in the second trimester, and 27.0% in the third trimester. The prevalence of iron deficiency was 46.7% in the first trimester, 78.1% in the second trimester, and 91.7% in the third trimester. No associations with dietary patterns were found. Single women had 1.85 times the odds (95% CI 1.07 to 3.18) of being anaemic than married women. Conclusions: Iron deficiency affects a large proportion of pregnant women in Latvia in all trimesters, with iron deficiency anaemia affecting pregnant women in the third trimester. Monitoring and intervention should be performed in a timely and more targeted manner.

Sphincter muscle activity before and after delivery: Does it depend on the type of birth?

AIM: There are ongoing discussions whether cesarean section is the safest mode of childbirth to prevent pelvic floor disorders. Pelvic floor electromyography (EMG) allows the analysis of external anal sphincter (EAS) function during voluntary contractions. The primary objective of this study was the evaluation of EMG amplitude of external anal sphincter in women who had vaginal delivery, compared to women who had cesarean section. The secondary objective was to evaluate the anal incontinence score changes before and after delivery between the groups, and to look for any relationship between the clinical and EMG findings. METHODS: Multichannel surface EMG was detected during maximal contractions in three sessions: (i) during pregnancy, (ii) 6 weeks after delivery and (iii) 1 year after delivery. Women were divided into two groups: cesarean section and vaginal delivery. RESULTS: External anal sphincter EMG amplitude decreases 6 weeks after vaginal deliveries from 10.1 to 8.6 µV with effect size of 0.4, but returns to baseline after 1 year. No differences were observed between groups in all other variables. CONCLUSION: No differences were observed after 1 year in EMG activity between the two groups; however, a slight decrease of sphincter muscle amplitude was noted 6 weeks after vaginal delivery. The delivery mode does not have effect on the EAS amplitude 1 year after delivery. Incontinence score slightly increased in both groups after delivery, with no significant differences between the two groups. No association was observed between the increase of incontinence score and the decrease of EMG signal amplitude.

Post-reproductive aged women: a lost generation in the cervical cancer screening programme.

OBJECTIVES: The aims of the study were to find out why some post-reproductive aged women did not participate in the organised cervical cancer screening programme in Latvia and to clarify factors that would motivate them to take part. METHODS: A cross-sectional study was carried out between January and July 2017 among female patients in three general practitioner (GP) practices. GP practice nurses used the Latvian national health service database to identify women aged 25-70 who had not participated in the organised programme for the last 3 years. Participants were asked to complete a specially developed questionnaire. The results were then compared between three age groups: 25-34, 35-49 and 50-70 years. RESULTS: Included in the study were 523 out of 992 women who had not attended screening; 41% were in the age group 50-70 years. Post-reproductive aged women statistically significantly more often did not take part in the programme because of lack of time (26.4%), too great a distance to the gynaecology screening clinic (10.4%), lengthy appointment waiting time (8.5%) and a belief that a smear test was unnecessary for them (8.5%); 32.1% of women in this age group indicated that if the cervical screen could be carried out by their GP it would facilitate their participation in the programme. CONCLUSION: Post-reproductive aged women in Latvia often do not attend cervical cancer screening. Analysis of personal and organisational barriers confirmed that the involvement of GPs would encourage older women to participate in the organised screening programme.

Assessment of Iodine and Selenium Nutritional Status in Women of Reproductive Age in Latvia.

Background and Objectives: Adequate dietary intake of iodine and selenium is essential during pregnancy. While iodine is vital for maternal thyroid function and fetal development, selenium contributes to the regulation of thyroid function and thyroid autoimmunity. This study aimed to assess the consumption of iodine- and selenium-containing products by women of reproductive age and the iodine and selenium nutritional status of pregnant women in Latvia. Materials and Methods: Population health survey (2010-2018) data were used to characterize dietary habits in women of reproductive age. Additionally, 129 pregnant women in the first trimester were recruited; they completed a questionnaire and were tested for thyroid function, urinary iodine concentration (UIC), and serum selenium and selenoprotein P levels. Results: The use of some dietary sources of iodine (e.g., milk and dairy products) and selenium (e.g., bread) has decreased in recent years. Less than 10% of respondents reported the use of iodized salt. The use of supplements has become more common (reported by almost 50% of respondents in 2018). Dietary habits were similar in pregnant women, but the use of supplements was even higher (almost 70%). Nevertheless, most supplements used in pregnancy had insufficient contents of iodine and selenium. Thyroid function was euthyreotic in all women, but 13.9% of participants had a thyroid peroxidase antibodies (TPO-ab) level above 60 IU/mL. The median UIC (IQR) was 147.2 (90.0-248.1) µg/gCr, and 52.8% of pregnant women had a UIC below 150 µg/gCr. The mean selenium (SD) level was 101.5 (35.6) µg/L; 30.1% of women had a selenium level below 80 µg/L. The median selenoprotein P level was 6.9 (3.1-9.0) mg/L. Conclusions: Iodine nutrition in Latvian population of pregnant women was near the lower limit of adequate and a third of the population had a selenium deficiency. Supplements were frequently used, but most did not contain the recommended amounts of iodine and selenium.

Could the correct side of mediolateral episiotomy be determined according to anal sphincter EMG?

INTRODUCTION AND HYPOTHESIS: Mediolateral episiotomy is one of the most frequent surgical interventions performed in obstetrics. There is conflicting evidence as to whether mediolateral episiotomy reduces the risk of obstetric anal sphincter injuries (OASI). Recent studies suggest that functional asymmetry of pelvic floor innervation exists in healthy women and is strongly associated with postpartum incontinence when the trauma occurs on the dominant side of innervation. Mediolateral episiotomy is the most common cause of perineal trauma during delivery, and the surgical incision is usually performed on the mediolateral right side. Surface electromyography (EMG) has been recently applied in obstetrics for detecting electrical activity of the external anal sphincter (EAS). METHODS: Two hundred and forty-five pregnant nulliparous women at their second and third trimester of pregnancy were recruited, and EMG signals were detected using a multichannel cylindric anal probe. Measurements were repeated and compared 6-8 weeks after delivery on a subgroup of 167 women who were divided in two groups according to EMG amplitude asymmetry before delivery and two subgroups according to type of delivery: (1A) asymmetric left, episiotomy right; (1B) asymmetric left, other types of deliveries; (2A) asymmetric right, episiotomy right; (2B) asymmetric right, other type of deliveries. RESULTS: The reduction of EMG amplitude after right episiotomy was larger in women with right asymmetric sphincter compared with women with left asymmetry and women with other types of delivery. CONCLUSIONS: Prenatal EMG may be used to predict the impact of right-sided mediolateral episiotomy on EAS and perhaps also function following delivery.

The prevalence of genital warts in the Baltic countries: findings from national cross-sectional surveys in Estonia, Latvia and Lithuania.

OBJECTIVES: To assess the prevalence and correlates of self-reported genital warts (GWs) among women and men aged 18-45 years in the Baltic countries. METHODS: In 2011-2013 we performed a cross-sectional survey using a self-administered questionnaire to collect information on the history of clinically diagnosed GWs, sociodemographic characteristics and sexual behaviour. Probability sampling methods were used to invite 16,959 individuals representing the general population, of whom 7760 (45.8%) participated (Estonia: 1967 women, 1221 men; Latvia: 1525 women, 1525 men; Lithuania: 1522 women). RESULTS: The estimated lifetime prevalence of clinically diagnosed GWs in women was 4.6% (95% CI 3.8 to 5.5) in Estonia, 2.9% (95% CI 2.0 to 3.6) in Latvia and 1.5% (95% CI 1.2 to 2.0) in Lithuania. Among men, the corresponding values were 2.8% (95% CI 1.9 to 4.0) in Estonia and 1.9% (95% CI 1.3 to 2.6) in Latvia. The mean age at first episode of clinically diagnosed GW was 24.6 years (95% CI 23.6 to 25.5) for women and 24.5 years (95% CI 22.9 to 26.0) for men. A lifetime history of clinically diagnosed GW was associated with a history of sexually transmitted infections other than GW (adjusted OR (AOR) 3.0, 95% CI 2.1 to 4.3 for women; AOR 5.3, 95% CI 3.0 to 9.2 for men), and a higher number (5+) of lifetime sexual partners (AOR 2.9, 95% CI 1.9 to 4.2 for women; AOR 2.1, 95% CI 1.2 to 3.9 for men). Men living comfortably within their household income had higher odds for GW (AOR 1.9, 95% CI 1.1 to 3.2). CONCLUSIONS: Our estimated prevalence of clinically diagnosed GWs was lower than estimates from the general population of other European countries.

Iodine deficiency during pregnancy: a national cross-sectional survey in Latvia.

OBJECTIVE: Low iodine intake during pregnancy may cause thyroid dysfunction, which results in inadequate fetal brain development. In the absence of a universal salt iodization programme, we conducted a nationwide survey of iodine deficiency in pregnant women in Latvia. DESIGN: A countrywide twenty-cluster survey, with at least twenty women per cluster. Participants completed a questionnaire on dietary habits concerning iodine intake (n 739). Thyroid function (thyroid-stimulating hormone, free thyroxine and thyroperoxidase antibodies) was measured (n 550). Urinary iodine was measured using the ammonium persulfate method (n 696). SETTING: The survey was performed in all regions of Latvia during the spring and autumn seasons in 2013. SUBJECTS: Pregnant women (n 829). RESULTS: The median creatinine (Cr)-standardized urinary iodine concentration (UIC) was 80·8 (interquartile range (IQR) 46·1-130·6) µg/g Cr or 69·4 (IQR 53·9-92·6) µg/l during pregnancy, and 81% of pregnant women had UIC levels below the WHO recommended range of 150-250 µg/g Cr. The UIC was lowest during the first trimester of pregnancy, 56·0 (IQR 36·4-100·6) µg/g Cr, reaching higher concentrations of 87·5 (IQR 46·4-141·7) µg/g Cr and 86·9 (IQR 53·8-140·6) µg/g Cr in the second and third trimesters, respectively. Women taking supplements containing ≥150 µg iodine (6·8% of respondents) had non-significantly higher UIC than did women without supplementation (96·2 v. 80·3 µg/g Cr, respectively, P=NS). Thyroperoxidase antibody concentration did not correlate significantly with UIC: Spearman's ρ=-0·012, P=0·78. CONCLUSIONS: The median UIC indicates iodine deficiency in pregnant women in Latvia. Iodine supplementation (150 µg daily) and regular UIC monitoring should be suggested to overcome iodine deficiency and to reach the recommended levels without inducing autoimmune processes.

Human Leucocyte Antigen Class II Risk and Protective Alleles in Women with Cervical Intraepithelial Neoplasia.

Background: Persistent human papillomavirus (HPV) infection is a necessary cause for development of cervical precancerous lesions and cervical cancer, however, only a small percentage of women progress to cervical cancer. The local immune response, determined, among other factors, by Human Leucocyte Antigen (HLA) genes, is thought to be significant. Still the results of genome studies are inconsistent and differ between ethnical populations. The aim of the study was to assess an association between HLA-DQA1*; DQB1*; DRB1* allele's genetic variants between women with cervical precancerous lesions and healthy controls in Latvia. Materials and methods: From January until April 2017 we enrolled 84 consecutive patients referred for colposcopy to Riga East University Hospital (Latvia) due to abnormal cervical cytology results. 57 women who came for a regular check-up and had normal cytology smears were included in the control group. Material from the cervix was taken for subsequent HLA genotyping of 13 DRB1*, 8 DQA1*, and 12 DQB1* alleles. Colposcopy was performed on all participants. In case of visual suspicion for CIN cervical biopsy was done. Results: There were 57 "no CIN" patients, 23 histologically proven CIN 1 and 61 CIN2+ cases in the study population. CIN2+ was more often associated with DQA1*0401 (OR 6.68, 95% CI 1.47-30.29, p=0.014), DRB*15 (OR 2.99, 95% CI 1.22-7.39, p=0.017), DQB1*0401 (OR 2.91, 95%CI 1.11-7.68, p=0.03), DQA1*0103 (OR 2.72, 95% CI 1.02-7.21, p=0.045), DRB1*11 (OR 2.42, 95% CI 1.10-5.33, p=0.029) and DQB1*0301 (OR 1.94, 95% CI 1.12-3.38, p=0.018). Women with "no CIN" more often had DQB1*0501 (OR 0.17, 95% CI 0.04-0.81, p=0.026), DRB1*16 (OR 0.21, 95% CI 0.06-0.78, p=0.019), DQA1*0301 (OR 0.35, 95% CI 0.14-0.87, p=0.024) and DRB1*14 (OR 0.59, 95% CI 0.01-0.46, p=0.007). Conclusions: In the current study we have demonstrated a strong association with risk and protective HLA class II alleles that are determined by the HLA-DRB1*; DQA1*; DQB1*.

Impact of vaginal ascorbic acid on abnormal vaginal microflora.

PURPOSE: To evaluate the impact of vaginal ascorbic acid (vitamin C) as a treatment/maintenance regimen on increased vaginal pH and abnormal microflora on wet mounts in premenopausal women. METHODS: A randomized study of 140 asymptomatic, low-risk pregnant and non-pregnant premenopausal women with vaginal pH ≥ 4.5 and a variety of partly/completely disrupted Lactobacillus microflora patterns on wet mounts in five outpatient clinics was carried out. Participants were randomized to the intervention group [250 mg vitamin C tablets vaginally at bedtime once a day for 6 days (treatment phase), followed by a one tablet per week, for 12 weeks (maintenance phase)] or the control group (no treatment). Outcomes were evaluated 4 months after randomizing, i.e., 2-3 weeks after the last vitamin C tablet insertion. RESULTS: Normalization to normal flora was observed in 51.4 % of all ascorbic acid and in 24.3 % of control group patients (difference 27.1 %, 95 % CI 11.7-42.6, p < 0.05, ITT population). In the per protocol population, normalization was confirmed in 53.5 % of the intervention and 22.4 % of the control group (difference 31 %, 95 % CI 14.3-47.8, p < 0.05). Results of pregnant subgroup analysis showed better outcomes for the subgroup: difference of normalization rate between ascorbic acid and control group was 41.2 % (95 % CI 21.8-60.1, p < 0.05). Itching occurred in 19 %; 23 % of women reported irritation and 10 % stopped the treatment because of side effects. CONCLUSIONS: Vaginal ascorbic acid improves abnormal vaginal pH and microflora, especially in pregnant women, but is not well tolerated by all women.

In-Depth Analysis of Caesarean Section Rate in the Largest Secondary Care-Level Maternity Hospital in Latvia.

There is no surgical intervention without risk. A high rate of caesarean sections (CSs) impacts on maternal and newborn mortality and morbidity. For optimisation of the CS rate, regular monitoring is necessary. In 2015, the World Health Organization recommended the Robson classification as a global standard for assessing, monitoring, and comparing CS rates. We analysed all births in 2019 in the Riga Maternity Hospital-a secondary-level monodisciplinary perinatal care hospital in Latvia-according to the Robson classification, seeking to identify which groups make the biggest contribution to the overall CS rate. In total, 5835 women were included. The overall CS rate was 21.5%. In our study, the largest contributors to the overall CS rate were as follows: Group 5 (33.3%); Group 2 (20.8%); and Group 1 (15.6%). The results of our deeper analysis of individual groups (Group 1 and 5) from our study may help to develop targeted interventions for specific subgroups of the obstetric population, effectively reducing both the overall rate of CS and the number of unnecessary CSs performed. The CS rate reduction strategy should be based on decreasing CSs in Group 1 and encouraging VBAC, thus decreasing the number of women undergoing two or more CSs in future.

Adaptive changes in the splenic artery and left portal vein in fetal growth restriction.

OBJECTIVES: The purpose of this study was to determine whether a low splenic artery pulsatility index (PI) and reduced flow through the left portal vein are involved in redistribution of fetal growth restriction. METHODS: Forty-two women with prenatally diagnosed intrauterine growth restriction of singleton fetuses were included. The next pregnant woman with an appropriately growing fetus, matched for gestational age, was selected as a control. Blood flow velocities were measured in the splenic artery and left portal vein. Obstetric and perinatal information was obtained from standardized medical records. RESULTS: The blood flow through the left portal vein was significantly reduced compared with the controls (P < .0001). Placental impairment in fetal growth restriction was clearly linked to a decreased splenic artery PI (P = .0004). In growth-restricted fetuses with reduced left portal vein flow and a splenic artery PI below the 5th percentile, perinatal mortality, a low 5-minute Apgar score, and neonatal metabolic acidosis were observed significantly more often (P = .04, .01, and .004; P = .03, .03, and .006, respectively). CONCLUSIONS: Reduced blood flow through the left portal vein and low resistance in the splenic artery can be found in growth-restricted fetuses with adverse neonatal outcomes.

Ultrasound Simulation for Training Trainees when the Luxury Becomes Essential: Opinion and Evidence Obtained during the Latvian Research Council Project Implementation.

Background: Simulation as a proxy tool for conditional clinical training became a powerful technique for introducing trainees to the ultrasound imaging world, allowing them to become a trained sonographer taking into consideration different rates of progress in completing a specific task against the time and ensuring the long-lasting maintenance of the obtained practical skills. Adding a costly, but effective high-fidelity simulator to the residency program justified the expense, demonstrating efficiency of training for improving the clinical performance and confidence of trainees. Materials and methods: A pilot study in Riga Maternity Hospital within the framework of the study "Role of metabolome, biomarkers and ultrasound parameters in successful labor induction" (Fundamental and Applied Research Programme lzp-2021/1-0300) was performed between March 1st 2022 and 31st April 2022. A virtual-reality simulator (ScanTrainer, MedaphorTM, Cardiff, UK) was used with the teaching module for assessment of the uterine cervix. Five trainees in obstetrics and two young specialists included in the study. None of them had Fetal Medicine Foundation certificate of competence in the assessment of the uterine cervical lenght before. The time used on the simulator, the number of simulations and a mean confidence in cervical length assessment before and after simulation were recorded. Results: The study on assesment of uterine cervical lenght demonstrated statistically significant increase in confidence (p=0.008) and statistically significant decrease in time needed to complete correctly the same tasks for the trainees (p=0.008) that shows a positive learning curve over the time of training on ScanTrainer, Medaphor. Conclusions: The simple task allows to become a certified specialist in uterine cervical assessment in the short period of time. That support the productiveness of the simulation-based education. The training program should be updated taking into consideration simulation curriculum.

Women's perspectives on the quality of maternal and newborn care in childbirth during the COVID-19 pandemic in Latvia: Results from the IMAgiNE EURO study on 40 WHO standards-based quality measures.

OBJECTIVE: To investigate women's perspectives on the quality of maternal and newborn care (QMNC) around the time of childbirth during the COVID-19 pandemic in Latvia, comparing the years 2020 and 2021, among women who went into labor or had a prelabor cesarean. METHODS: Women giving birth in healthcare facilities in Latvia from March 1, 2020, to October 28, 2021, answered an online questionnaire including 40 WHO standards-based quality measures. Descriptive and multivariate quantile regression analyses were performed to compare QMNC in 2020 and 2021. RESULTS: 2079 women were included in the analysis: 1860 women who went into labor (group 1) and 219 with prelabor cesarean (group 2). Among group 1, 66.4% (n = 99/149) of women received fundal pressure in an instrumental vaginal birth, 43.5% (n = 810) lacked involvement in choices, 17.4% (n = 317) reported suffering abuse, 32.7% (n = 609) reported inadequate breastfeeding support while 5.2% (n = 96) lack of early breastfeeding. A significant reduction in QMNC due to the COVID-19 pandemic was reported by 29.5% (n = 219) and 25.0% (n = 270) of respondents in 2020 and 2021, respectively (P = 0.045). Multivariate analyses highlighted a significantly lower QMNC index for 2020 compared with 2021 (P < 0.001). CONCLUSION: This first study investigating QMNC in Latvia showed significant gaps in QMNC perceived by respondents, with slightly better results in 2021. Appropriate healthcare strategies to improve health care for women and newborns in Latvia are required. CLINICALTRIALS: gov Identifier:NCT04847336.

Individual and country-level variables associated with the medicalization of birth: Multilevel analyses of IMAgiNE EURO data from 15 countries in the WHO European region.

OBJECTIVE: To investigate potential associations between individual and country-level factors and medicalization of birth in 15 European countries during the COVID-19 pandemic. METHODS: Online anonymous survey of women who gave birth in 2020-2021. Multivariable multilevel logistic regression models estimating associations between indicators of medicalization (cesarean, instrumental vaginal birth [IVB], episiotomy, fundal pressure) and proxy variables related to care culture and contextual factors at the individual and country level. RESULTS: Among 27 173 women, 24.4% (n = 6650) had a cesarean and 8.8% (n = 2380) an IVB. Among women with IVB, 41.9% (n = 998) reported receiving fundal pressure. Among women with spontaneous vaginal births, 22.3% (n = 4048) had an episiotomy. Less respectful care, as perceived by the women, was associated with higher levels of medicalization. For example, women who reported having a cesarean, IVB, or episiotomy reported not feeling treated with dignity more frequently than women who did not have those interventions (odds ratio [OR] 1.37; OR 1.61; OR 1.51, respectively; all: P < 0.001). Country-level variables contributed to explaining some of the variance between countries. CONCLUSION: We recommend a greater emphasis in health policies on promotion of respectful and patient-centered care approaches to birth to enhance women's experiences of care, and the development of a European-level indicator to monitor medicalization of reproductive care.

Factors related to elevated vaginal pH in the first trimester of pregnancy.

OBJECTIVE: To assess different bacterial and epidemiological factors associations with increased vaginal pH in the pregnant women population during the first trimester. DESIGN: A cross-sectional, observational study. SETTING: Three outpatient clinics in Riga. POPULATION: From July 2009 until January 2010, 139 unselected consecutive pregnant women at the first prenatal visit. METHODS: Pregnant women were submitted to an interview, vaginal examination and vaginal specimen collection for pH measurement and native microscopy. MAIN OUTCOME MEASURES: Vaginal pH ≥4.5 was considered as elevated. Abnormal bacterial microflora was classified according to Donders. RESULTS: Elevated vaginal pH was significantly associated with bacterial vaginosis (p < 0.001), aerobic vaginitis (p < 0.001) and mixed aerobic vaginitis and bacterial vaginosis flora (p < 0.001) and presence of sperm cells in the smears (p= 0.024). Most cases with sperm were associated with abnormal vaginal flora. Normal lactobacillary morphotypes were more often found in the pH ≤4.4 group (p < 0.001), while leptosomic and short types were found more frequently with increased pH. CONCLUSIONS: Elevated vaginal pH is associated with different types of abnormal vaginal flora and the presence of sperm cells.

Microscopic lesions of placenta and Doppler velocimetry related to fetal growth restriction.

PURPOSE: The purpose of the study was to find an association between the uterine and umbilical arteries blood flow patterns in growth-restricted (FGR) and normal fetuses and placental microscopic lesions. METHODS: Fifty women with prenatally suspected and post-delivery confirmed FGR of singleton fetuses were enrolled in a case-controlled follow-up study from May 2007 to December 2008. Unselected patients with appropriately growing fetuses, matched for gestational age, served as controls. Uterine and umbilical Doppler waveforms were recorded before delivery. RESULTS: Compared with control group with normal Doppler, FGR women with abnormal Doppler velocimetry of uterine and umbilical arteries had more intervillous thrombi (p = 0.01 and p < 0.0001, respectively) and villous infarctions (p = 0.02 and p = 0.0003, respectively). Thickening of the basal membrane and villitis was clearly linked to the FGR (p = 0.006 and p = 0.01). Vasculitis, on the other hand, is linked to normal growth, without affecting Doppler velocities. CONCLUSIONS: Abnormal Doppler may predict hemorrhagic and ischemic placental lesions in FGR pregnancies and may lead to future improvement of the management of current and subsequent pregnancies.

Aerobic Vaginitis-Underestimated Risk Factor for Cervical Intraepithelial Neoplasia.

The aim of this study is to analyse the association between vaginal microbiota and the histological finding of CIN. From July 2016 until June 2017, we included 110 consecutive patients with abnormal cervical cytology results referred for colposcopy to Riga East Clinical University Hospital Outpatient department in the study group. 118 women without cervical pathology were chosen as controls. Certified colposcopists performed interviews, gynaecological examinations and colposcopies for all participants. Material from the upper vaginal fornix was taken for pH measurement and wet-mount microscopy. Cervical biopsy samples were taken from all subjects in the study group and in case of a visual suspicion for CIN in the control group. Cervical pathology was more often associated with smoking (34.6% vs. 11.0%, p < 0.0001), low education level (47.2% vs. 25.5%, p = 0.001), increased vaginal pH (48.2% vs. 25.4%, p < 0.0001), abnormal vaginal microbiota (50% vs. 31.4%, p = 0.004) and moderate to severe aerobic vaginitis (msAV) (13.6% vs. 5.9%, p = 0.049) compared to controls. The most important independent risk factors associated with CIN2+ were smoking (OR 3.04 (95% CI 1.37-6.76), p = 0.006) and msAV (OR 3.18 (95% CI 1.13-8.93), p = 0.028). Bacterial vaginosis (BV) was found more often in CIN1 patients (8/31, 25.8%, p = 0.009) compared with healthy controls (8/118, 6.8%), or CIN2+ cases (8/79, 10.1%). In the current study msAV and smoking were the most significant factors in the development of CIN in HPV-infected women, especially high grade CIN. We suggest that AV changes are probably more important than the presence of BV in the pathogenesis of CIN and progression to cervix cancer and should not be ignored during the evaluation of the vaginal microbiota.

Preventable maternal risk factors and association of genital infection with fetal growth restriction.

INTRODUCTION: Maternal risk factors may interfere with mechanisms regulating fetal growth. The aim of the present study was to determine which sociodemographic and reproductive risk factors may be related to fetal growth restriction (FGR), with a special focus on determinants possible for preventive intervention. MATERIALS AND METHODS: The study period is from May 2007 until December 2009. Data about lifestyle habits were collected by use of a detailed questionnaire in 65 women who attended Riga Maternity Hospital with the confirmed diagnosis of intrauterine FGR of a singleton fetus, and in 65 matched controls with normal pregnancies. RESULTS: Being unmarried (p = 0.04), having pregnancy-related blood pressure rise (p = 0.02), current (p = 0.01) and pre-pregnancy smoking (p = 0.01) and history of more than 3 pregnancy failures (p = 0.04) were more frequent in women with FGR than controls. Surprisingly, the finding of genital infection (STI) during pregnancy (p = 0.006) was also strongly associated with FGR. CONCLUSIONS: Obviously, several maternal risk factors play an important role in FGR. Besides refraining from smoking, screening and treating for STI may not only prevent preterm birth, but also FGR. Identifying such anticipating factors would likely have the potential impact if detected before conception, or as early as possible in gestation.
