Trends over 50 years with liberal abortion laws in the Nordic countries.

BACKGROUND: During the 1970s the Nordic countries liberalized their abortion laws. OBJECTIVE: We assessed epidemiological trends for induced abortion on all Nordic countries, considered legal similarities and diversities, effects of new medical innovations and changes in practical and legal provisions during the subsequent years. METHODS: New legislation strengthened surveillance of induced abortion in all countries and mandated hospitals that performed abortions to report to national abortion registers. Published data from the Nordic abortion registers were considered and new comparative analyses done. The data cover complete national populations. RESULTS AND CONCLUSIONS: After an increase in abortion rates during the first years following liberalization, the general abortion rates stabilized and even decreased in all Nordic countries, especially for women under 25 years. From the mid-1980s higher awareness about pregnancy termination led women to present at an earlier gestational age, which was accelerated by the introduction of medical abortion some years later. Most terminations (80-86%) are now done before the 9th gestational week in all countries, primarily by medical rather than surgical means. Introduction of routine ultrasound screening in pregnancy during the late 1980s, increased the number of 2nd trimester abortions on fetal anomaly indications without an overall increase in the proportion of 2nd relative to 1st trimester abortions. Further refinement of ultrasound screening and non-invasive prenatal diagnostic methods led to a slight increase in the proportion of early 2nd trimester abortions after the year 2000. Country-specific differences in abortion rates have remained stable over the 50 years of liberalized abortion laws.

How have changes in accessibility and public funding influenced contraceptive use among Norwegian adolescents? A cohort study.

INTRODUCTION: The Norwegian Government introduced in 2002 a reimbursement scheme for hormonal contraceptives to adolescents at the same time as public health nurses and midwives received authorization to prescribe hormonal contraceptives. This study examines the impact of increased accessibility and public funding on hormonal contraceptive use among adolescents. MATERIAL AND METHODS: The Norwegian Prescription Database, Statistics Norway, and Norwegian Institute of Public Health served as data sources for this cohort study. The study population comprised 174 653 Norwegian women born 1989-1990, 1994-1995, and 1999-2000. We examined use of hormonal contraceptives through dispensed prescriptions from age 12 through age 19 with duration of first continuous use as primary outcome. The statistical analyses were done in SPSS using chi-squared test, survival analysis, and Joinpoint regression analysis with p-values < 0.05. RESULTS: By age 19, ~75% of the cohorts had used at least one hormonal method. The main providers of the first prescription were general practitioners and public health nurses. Starters of progestogen-only pills (POPs) have increased across the cohorts, while starters of combined oral contraceptives (COCs) have decreased. The use of long-acting reversible contraceptives (LARCs) has increased since its inclusion in the reimbursement scheme (2015). Most switchers shifted from COCs or POPs as a start method to implants after LARCs became part of the reimbursement scheme. There has been a significant increase across the cohorts in the number of women who continuously used hormonal contraceptives from start to the end of the calendar year they became 19 years with the same method and after switching methods. We could not correlate changes in decreasing trends for teenage births or induced abortions (Joinpoint analysis) to time for implementation or changes in the reimbursement of hormonal contraceptives from 2002. CONCLUSIONS: Primarily public health nurses and to a lesser extent midwives became soon after they received authorization to prescribe COCs important providers. The expansion of the reimbursement scheme to cover POPs, patches, vaginal ring, and depot medroxyprogesterone acetate in 2006 had minor impact on increasing the proportion of long-term first-time users. However, the inclusion of LARCs in 2015 significantly increased the proportion of long-term first-time hormonal contraceptive users.

Prevention of obstetric anal sphincter injuries with perineal support and lateral episiotomy: A historical cohort study.

INTRODUCTION: There are many risk factors for obstetric anal sphincter injury (OASIS) and the interaction between these risk factors is complex and understudied. The many observational studies that have shown a reduction of OASIS rates after implementation of perineal support have short follow-up time. We aimed to study the effect of integration of active perineal support and lateral episiotomy on OASIS rates over a 15-year period and to study interactions between risk factors known before delivery. MATERIAL AND METHODS: We performed a historical cohort study over the periods 1999-2006 and 2007-2021 at Stavanger University Hospital, Norway. The main outcome was OASIS rates. Women without a previous cesarean section and a live singleton fetus in cephalic presentation at term were eligible. The department implemented in 2007 the Finnish concept of active perineal protection, which includes support of perineum, control of fetal expulsion, good communication with the mother and observation of perineal stretching. The practice of mediolateral episiotomy was replaced with lateral episiotomy when indicated. We analyzed the OASIS rates in groups with and without episiotomy stratified for delivery mode, fetal position at delivery and for parity, and adjusted for possible confounders (maternal age, gestational age, oxytocin augmentation and epidural analgesia). RESULTS: We observed a long-lasting reduction in OASIS rates from 4.9% to 1.9% and an increase in episiotomy rates from 14.4% to 21.8%. Lateral episiotomy was associated with lower OASIS rates in nulliparous women with instrumental vaginal deliveries and occiput anterior (OA) position; 3.4% vs 10.1% (OR 0.31; 95% CI: 0.24-0.40) and 6.1 vs 13.9% (OR 0.40; 95% CI: 0.19-0.82) in women with occiput posterior (OP) position. Lateral episiotomy was also associated with lower OASIS rates in nulliparous women with spontaneous deliveries and OA position; 2.1% vs 3.2% (OR 0.62; 95% CI: 0.49-0.80). The possible confounders had little confounding effects on the risk of OASIS in groups with and without episiotomy. CONCLUSIONS: We observed a long-lasting reduction in OASIS rates after implementation of preventive procedures. Lateral episiotomy was associated with lower OASIS rates in nulliparous women with an instrumental delivery. Special attention should be paid to deliveries with persistent OP position.

Minor changes in the incidence of primary and secondary involuntary childlessness across birth cohorts 1916 to 1975, but major differences in treatment success.

There have been tremendous advances in assisted reproductive technologies (ARTs) over the past 50 years. The present study assessed infertility outcomes among women of reproductive age during this period. The seventh survey of the Tromsø Study (Tromsø7, 2015-16) recruited Tromsø residents aged 40-98 years. The questionnaire collected information on sociodemographics and infertility, as well as data from a wide range of validated health questionnaires. Primary involuntary childlessness was defined as reporting one or more of the following: the clinical definition of infertility (i.e., infertility period of >1 year), infertility examination, use of ART, and/or the birth of a child conceived during ART. Women with secondary involuntary childlessness were those who reported infertility experience and had least one naturally conceived child. Parous women without infertility experience were classified as fertile, and nulliparous women without infertility experience as voluntarily childless. The main exposure was birth cohort (1916-35, aged 80-98 years; 1936-45, aged 70-79 years; 1946-55, aged 60-69 years; 1956-65, aged 50-59 years; 1966-75, aged 40-49 years). The incidence of primary involuntary childlessness was significantly higher in the 1956-75 cohort (6.0%; 95% CI: 5.4-6.6) than the 1916-55 cohort (3.7%; 95% CI: 3.2-4.3). The incidence of secondary involuntary childlessness was higher than that of primary involuntary childlessness across all birth cohorts and was highest for the 1966-75 cohort (10%), with no differences observed across the other birth cohorts (6-7%). An increasing proportion of women from the oldest to the youngest birth cohorts reported infertility examination and ART. ART success increased substantially with time, reaching 58% for primary and 46% for secondary infertility in the 1966-75 cohort. Voluntarily childless women comprised 5-6% of the 1916-55 cohort and 9-10% of the 1956-75 cohort. There were minor differences in the incidence of primary and secondary involuntary childlessness across the 1916-75 cohorts. Advances in ART over the past 50 years comprised 2.0% and 3.3% of population growth in the 1956-65 and 1966-75 cohorts, respectively: a remarkable achievement.

Risk of Intraepithelial Neoplasia Grade 3 or Worse (CIN3+) among Women Examined by a 5-Type HPV mRNA Test during 2003 and 2004, Followed through 2015.

BACKGROUND: The study's purpose was to evaluate the performance of a five-type HPV mRNA test to predict cervical intraepithelial neoplasia grade 3 or worse (CIN3+) during up to 12 years of follow-up. METHODS: Overall, 19,153 women were recruited by gynecologists and general practitioners in different parts of Norway between 2003 and 2004. The study population comprised 9582 women of these women, aged 25-69 years with normal cytology and a valid five-type HPV mRNA test at baseline. Follow-up for CIN3+ through 2015 was conducted in the Norwegian Cervical Cancer Screening Programme. RESULTS: The cumulative incidence of CIN3+ by baseline status for HPV mRNA-positive and mRNA-negative women were 20.8% and 1.1%, respectively (p < 0.001). Age did not affect the long-term ability of the HPV mRNA test to predict CIN3+ during follow-up. CONCLUSION: The low long-term risk of CIN3+ among HPV mRNA-negative women and the high long-term risk among HPV mRNA-positive women strengthen the evidence that the five-type HPV mRNA test is an appropriate screening test for women of all ages. Our findings suggest that women with a negative result may extend the screening interval up to 10 years.

13-Type HPV DNA Test versus 5-Type HPV mRNA Test in Triage of Women Aged 25-33 Years with Minor Cytological Abnormalities-6 Years of Follow-Up.

BACKGROUND: A specific, cost-effective triage test for minor cytological abnormalities is essential for cervical cancer screening among younger women to reduce overmanagement and unnecessary healthcare utilization. We compared the triage performance of one 13-type human papillomavirus (HPV) DNA test and one 5-type HPV mRNA test. METHODS: We included 4115 women aged 25-33 years with a screening result of atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSIL) recorded in the Norwegian Cancer Registry during 2005-2010. According to Norwegian guidelines, these women went to triage (HPV testing and repeat cytology: 2556 were tested with the Hybrid Capture 2 HPV DNA test, which detects the HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68; and 1559 were tested with the PreTect HPV-Proofer HPV mRNA test, which detects HPV types 16, 18, 31, 33, and 45). Women were followed through December 2013. RESULTS: HPV positivity rates at triage were 52.8% and 23.3% among DNA- and mRNA-tested women (p < 0.001), respectively. Referral rates for colposcopy and biopsy and repeat testing (HPV + cytology) after triage were significantly higher among DNA-tested (24.9% and 27.9%) compared to mRNA-tested women (18.3% and 5.1%), as were cervical intraepithelial neoplasia grade 3 or worse (CIN3+) detection rates (13.1% vs. 8.3%; p < 0.001). Ten cancer cases were diagnosed during follow-up; eight were in DNA-tested women. CONCLUSION: We observed significantly higher referral rates and CIN3+ detection rates in young women with ASC-US/LSIL when the HPV DNA test was used at triage. The mRNA test was as functional in cancer prevention, with considerably less healthcare utilization.

May Women with a Negative Co-Test at First Follow-Up Visit Return to 3-Year Screening after Treatment for Cervical Intraepithelial Neoplasia?

BACKGROUND: The Norwegian Cervical Cancer Screening Programme recommends that women treated for cervical intraepithelial neoplasia (CIN) only be returned to 3-year screening after receiving two consecutive negative co-tests, 6 months apart. Here we evaluate adherence to these guidelines and assessed the residual disease, using CIN3+ as the outcome. METHODS: This cross-sectional study comprised 1397 women, treated for CIN between 2014 and 2017, who had their cytology, HPV, and histology samples analyzed by a single university department of pathology. Women who had their first and second follow-up at 4-8 and 9-18 months after treatment were considered adherent to the guidelines. The follow-up ended on 31 December 2021. We used survival analysis to assess the residual and recurrent CIN3 or worse among women with one and two negative co-tests, respectively. RESULTS: 71.8% (1003/1397) of women attended the first follow-up 4-8 months after treatment, and 38.3% were considered adherent at the second follow-up. Nearly 30% of the women had incomplete follow-up at the study end. None of the 808 women who returned to 3-year screening after two negative co-tests were diagnosed with CIN3+, whereas two such cases were diagnosed among the 887 women who had normal cytology/ASCUS/LSIL and a negative HPV test at first follow-up (5-year risk of CIN3+: 0.24, 95%, CI: 0.00-0.57 per 100 woman-years). CONCLUSIONS: The high proportion of women with incomplete follow-up at the end of the study period requires action. The risk of CIN3+ among women with normal cytology/ASCUS/LSIL and a negative HPV test at first follow-up is indicative of a return to 3-year screening.

Hormonal IUD is the major hormonal contraceptive method used among women aged 40-49 years: Data from the 2015-16 Tromsø Study, Norway.

OBJECTIVE: This study aims to investigate hormonal contraceptive (HC) use and user characteristics in women aged 40-49 years in Norway, as little is known on use of HCs in this age segment. MATERIAL AND METHODS: This prevalence study included 2296 women aged 40-49 years who participated in the 2015-16 Tromsø Study, which collected self-reported sociodemographic information and data from a wide range of validated health questionnaires. The participants had been sexually active the last 12 months prior enrollment, were not pregnant, not trying to conceive, and had no prior fertility problems. We categorized use of HC into three groups; no HC use, hormonal IUD use and other HC use. Explanatory variables included demographic, educational, economic and general health variables. All analyses were performed in SPSS with chi-square test and logistic regression at significance level p < 0.05. RESULTS: Nearly 50 % of the study sample reported HC use with hormonal IUD use as the major method (39.5 %/40-44 years; 43.4 %/45-49 years old women). There were no differences in HC use by partner status, educational level, or BMI. Though statistically significant, we found only minor differences in HC use by occupational status, gross household income, and general health status, with higher proportions of women with no paid work, the lowest income, and poor health status reporting no HC use. CONCLUSION: The high HC use and the minor differences found across demographic and socioeconomic parameters indicate that HC use, and hormonal IUD use in particular, is widely used among middle-aged women living in the city of Tromsø.

Changes in cesarean section rates after introduction of a punitive financial policy in Georgia: A population-based registry study 2017-2019.

BACKGROUND: There is little research on how financial incentives and penalties impact national cesarean section rates. In January 2018, Georgia introduced a national cesarean section reduction policy, which imposes a financial penalty on hospitals that do not meet their reduction targets. The aim of this study was to assess the impact of this policy on cesarean section rates, subgroups of women, and selected perinatal outcomes. METHODS: We included women who gave birth from 2017 to 2019 registered in the Georgian Birth Registry (n = 150 534, nearly 100% of all births in the country during this time). We then divided the time period into pre-policy (January 1, 2017, to December 31, 2017) and post-policy (January 1, 2018, to December 31, 2019). An interrupted time series analysis was used to compare the cesarean section rates (both overall and stratified by parity), neonatal intensive care unit transfer rates, and perinatal mortality rates in the two time periods. Descriptive statistics were used to assess differences in maternal socio-demographic characteristics. RESULTS: The mean cesarean section rate in Georgia decreased from 44.7% in the pre-policy period to 40.8% in the post-policy period, mainly among primiparous women. The largest decrease in cesarean section births was found among women <25 years of age and those with higher education. There were no significant differences in the neonatal intensive care unit transfer rate or the perinatal mortality rate between vaginal and cesarean section births in the post-policy period. CONCLUSION: The cesarean section rate in Georgia decreased during the 2-year post-policy period. The reduction mainly took place among primiparous women. The policy had no impact on the neonatal intensive care unit transfer rate or the perinatal mortality rate. The impact of the national cesarean section reduction policy on other outcomes is not known.

Reproductive changes among women in their 40s: A cross-sectional study.

INTRODUCTION: The aim was to describe and compare changes in the reproductive pattern of women in their 40s observed over a decade in Scandinavia. MATERIAL AND METHODS: Cross-sectional study using the total population of women aged 40-49 years between 2008-2018 in Denmark, Norway and Sweden (on average n = 1.5 million). Aggregated data concerning birth and induced abortion rate were collected and analyzed from national health registers. National data on redeemed prescriptions of hormonal contraceptives in the three countries were collected from prescription registers. Births after spontaneous and assisted conceptions were identified by using cross-linked data on deliveries from the Medical Birth Registers and National Registers of Assisted Reproduction in the three countries. RESULTS: Use of hormonal contraception increased among women aged 40-44 years in Denmark from 24% to 31%, in Sweden from 27% to 30%, and in Norway from 22% to 24%. The levonorgestrel-releasing intrauterine device was the most frequently used method in all countries. Birth rates among women 40-44 years increased continuously from 9.5 to 12/1000 women in Denmark and from 11.7 to 14.3/1000 in Sweden, but remained stable in Norway at ~11/1000 women. There was a doubling of assisted conceptions in Denmark from 0.71 to 1.71/1000 women, Sweden from 0.43 to 0.81/1000 and Norway from 0.25 to 0.53/1000 women 40-49 years of age. Sweden had the highest induced abortion rate (7.7 to 8.1/1000 women) in women aged 40-49 years during the study period. CONCLUSIONS: From 2008 to 2018, birth rates continuously increased among women aged 40-49 years in Denmark and Sweden and births resulting from assisted reproductive technology doubled in all three countries.

Changed definition of disease and broader screening criteria had little impact on prevalence of gestational diabetes mellitus.

INTRODUCTION: There are major controversies in screening for gestational diabetes mellitus (GDM). The present study evaluates the impact of the 2017 revised guidelines for GDM screening and a changed definition of GDM in Norway. MATERIAL AND METHODS: We used a case-series design and included women with no pre-pregnancy diabetes mellitus, who gave birth after gestational week 29 to a singleton fetus at the University Hospital of North Norway, Tromsø, or at a local maternity ward in Troms county, during the first 6 months of 2013 (before group, n = 676) and 2018 (after group, n = 673). Data were collected from antenatal records, maternal health information sheets, and electronic medical records (Partus). We assessed the screening criteria age, parity, pre-pregnancy BMI, and ethnicity. Primary outcomes were change in size of the population eligible for GDM screening, screening adherence, and prevalence of GDM, and follow up of GDM (treatment and obstetric risk assessment at gestational week 36). Statistical analyses were done using IBM SPSS with chi-squared test. A p value less than 0.05 was considered statistically significant. RESULTS: The proportion of women eligible for GDM screening increased from 46.4% in the before group to 67.6% in the after group (+45%) (p < 0.01). However, screening adherence among eligible women was only 28.3% and 49.2% in the before and after groups, respectively (p < 0.01). Among screened women, 16.9% (15/89) and 10.7% (24/224), respectively, were diagnosed with GDM, resulting in an overall estimated prevalence of 2.2% (15/676) and 3.6% (24/673). Among women diagnosed with GDM, 13.3% received no follow up in 2013 and this proportion was 20.8% in 2018. The remaining women underwent obstetric risk assessment at gestational week 36 as advised in the guidelines. CONCLUSIONS: The introduction of broader screening criteria and a more liberal case definition increased the population eligible for GDM screening by 45%. The higher proportion of women screened resulted in an insignificant higher prevalence of GDM. Screening adherence was poor in both study groups. Stakeholders for obstetric care need to consolidate quality measures and revisit the screening algorithm.

Changes in maternal risk factors and their association with changes in cesarean sections in Norway between 1999 and 2016: A descriptive population-based registry study.

BACKGROUND: Increases in the proportion of the population with increased likelihood of cesarean section (CS) have been postulated as a driving force behind the rise in CS rates worldwide. The aim of the study was to assess if changes in selected maternal risk factors for CS are associated with changes in CS births from 1999 to 2016 in Norway. METHODS AND FINDINGS: This national population-based registry study utilizes data from 1,055,006 births registered in the Norwegian Medical Birth Registry from 1999 to 2016. The following maternal risk factors for CS were included: nulliparous/≥35 years, multiparous/≥35 years, pregestational diabetes, gestational diabetes, hypertensive disorders, previous CS, assisted reproductive technology, and multiple births. The proportion of CS births in 1999 was used to predict the number of CS births in 2016. The observed and predicted numbers of CS births were compared to determine the number of excess CS births, before and after considering the selected risk factors, for all births, and for births stratified by 0, 1, or >1 of the selected risk factors. The proportion of CS births increased from 12.9% to 16.1% (+24.8%) during the study period. The proportion of births with 1 selected risk factor increased from 21.3% to 26.3% (+23.5%), while the proportion with >1 risk factor increased from 4.5% to 8.8% (+95.6%). Stratification by the presence of selected risk factors reduced the number of excess CS births observed in 2016 compared to 1999 by 67.9%. Study limitations include lack of access to other important maternal risk factors and only comparing the first and the last year of the study period. CONCLUSIONS: In this study, we observed that after an initial increase, proportions of CS births remained stable from 2005 to 2016. Instead, both the size of the risk population and the mean number of risk factors per birth continued to increase. We observed a possible association between the increase in size of risk population and the additional CS births observed in 2016 compared to 1999. The increase in size of risk population and the stable CS rate from 2005 and onward may indicate consistent adherence to obstetric evidence-based practice in Norway.

Trends in initiation of hormonal contraceptive methods among teenagers born between 1989 and 1997 in Norway and the United States.

OBJECTIVE: To assess initiation of hormonal contraception among women aged 15-19 in the US and Norway by birth cohort. STUDY DESIGN: We used population-based survey (US) and administrative (Norway) data to estimate the cumulative probability of age at first use of hormonal contraception for female residents born between 1989 and 1997 in 3-year birth cohorts. Differences between countries were assessed using confidence intervals, and differences between birth cohorts were assessed using survival analysis. RESULTS: At age 15, first use of any hormonal method was higher among US respondents (16%-17% US vs 10%-13% Norway), whereas for ages 16 to 19 use was higher among Norwegian women (by age 19, 60%-64% US vs 76%-78% Norway). Similar patterns were observed for pill use; however, depot medroxy-progesterone acetate (DMPA), implant, and intrauterine device (IUD) use tended to be higher among US women. In both countries, cumulative first use of the pill, patch, ring, and DMPA declined across birth cohorts while first use of implants and IUDs increased. CONCLUSION: Age at initiation and type of first hormonal method use differed between US and Norwegian teenagers. These differences may contribute to the lower teen birth rate in Norway. IMPLICATIONS: Age at initiation of hormonal contraception among teenagers is earlier in Norway than in the United States, and types of hormonal methods used vary. These differences may contribute to the lower teen birth rate in Norway.

The impact of antenatal care utilization on admissions to neonatal intensive care units and perinatal mortality in Georgia.

INTRODUCTION: Appropriate antenatal care (ANC) utilization has direct, significant effects on perinatal mortality (PM). Georgia has one of the highest PM rates (11.7 per 1000 births) in Europe and launched a more intensive ANC programme in 2018. AIM: To evaluate the associations between the Adequacy of Prenatal Care Utilization (APNCU) index and neonatal intensive care unit (NICU) admission and PM in Georgia. METHODS: The Georgian Birth Registry (GBR), with linkage to the Vital Registration System, was used as the main data source; 148,407 eligible mothers and singleton newborns were identified during the observation period (2017-2019). The main exposure was ANC utilization, measured by the APNCU index, and the hospitalization registry was used to validate NICU admissions. Logistic regression analysis was used to assess the associations between the exposure and outcomes while controlling for potential confounders. RESULTS: The overall PM rate was 11.6/1000 births, and the proportion of newborns with a NICU admission was 7.8%. 85% of women initiated ANC before gestational age week 12. According to the APNCU index, 16% of women received inadequate, 10% intermediate, 38% adequate, and 36% intensive care. Women who received intermediate care had the lowest odds of PM (adjusted odds ratio [AOR] = 0.56, 95% confidence interval [CI] 0.45-0.70), and newborns of women who received inadequate care had the highest odds of NICU admission (AOR = 1.16, 95% CI 1.09-1.23) and PM (AOR = 1.18, 95% CI 1.02-1.36). CONCLUSION: ANC utilization is significantly associated with newborn asmissions to NICU and PM in Georgia. Women received inadequate care experienced the highest odds of newborn admissions to NICU and PM.

Factors Associated with Cesarean Section among Primiparous Women in Georgia: A Registry-based Study.

Cesarean section rates remain high in Georgia. As a cesarean section in the first pregnancy generally lead to a cesarean section in subsequent pregnancies, primiparous women should be targeted for prevention strategies. The aim of the study was to assess factors associated with cesarean section among primiparous women. The study comprised 17,065 primiparous women with singleton, cephalic deliveries at 37-43 weeks of gestation registered in the Georgian Birth Registry in 2017. The main outcome was cesarean section. Descriptive statistics and logistic regression analysis were used to identify factors associated with cesarean section. The proportion of cesarean section was 37.1% with regional variations from 14.2% to 57.4%. Increased maternal age, obesity and having a baby weighing ≥4000 g were all associated with higher odds of cesarean section. Of serious concern for newborn well-being is the high proportion of cesarean section at 37-38 weeks of gestation. Further research should focus on organizational and economical aspects of maternity care to uncover the underlying causes of the high cesarean section rate in Georgia.

Station of the fetal head at complete cervical dilation impacts duration of second stage of labor.

OBJECTIVE: To examine the association between station of the fetal head at complete cervical dilation and duration of second stage of labor, as well as prolonged second stage of labor, without and with the use of analgesia (EA). STUDY DESIGN: We conducted a population-based retrospective cohort study of 3311 women with a singleton pregnancy, gestational age ≥ 370 weeks, and cephalic presentation. Station of the fetal head at complete cervical dilation was categorized as at the pelvic floor, beneath the ischial spines, but above the pelvic floor, and at or above the ischial spines. In logistic regression analysis, we defined prolonged second stage of labor as > 2 h without and > 3 h with EA in nulliparous women, and > 1 h and > 2 h, respectively, in parous women. RESULTS: Survival curves demonstrated longer durations of second stage of labor in nulliparous women and women with EA in each category of station of fetal head. The adjusted odds ratio of prolonged second stage of labor was 13.1 (95% confidence interval (CI): 8.5-20.1) times higher when the fetal head was beneath the ischial spines, but above the pelvic floor, and 32.9 (95% CI: 21.5-50.2) times higher when the fetal head was at or above the ischial spines compared to at the pelvic floor. CONCLUSION: Station of the fetal head at complete cervical dilation was significantly associated with duration of second stage of labor.

Unattended Pregnancies and Perinatal Mortality in Georgia.

INTRODUCTION: The majority of pregnant women in Georgia attend the free-of-charge, national antenatal care (ANC) programme, but over 5% of pregnancies in the country are unattended. Moreover, Georgia has one of the highest perinatal mortality (PM) rates in Europe (11.7/1000 births). PURPOSE: To assess the association between unattended pregnancies and the risk of PM. METHODS: Data were extracted from the Georgian Birth Registry (GBR) and the national vital registration system. All mothers who had singleton births and delivered in medical facilities in Georgia in 2017-2018 were included in the study and categorised into attended pregnancies (at least one ANC visit during pregnancy) and unattended pregnancies (no ANC visits during pregnancy). After exclusions, the study sample included 101,663 women and their newborns, of which 1186 were either stillborn or died within 7 days. Logistic regression analysis was used to assess the effect of unattended pregnancies on PM. RESULTS: During the study period, the PM rate was 12.9/1000 births. In total, 5.6% of women had unattended pregnancies. The odds of PM among women with unattended pregnancies were more than double those among women with attended pregnancies (odds ratio=2.21, [95% confidence interval: 1.81-2.70]). Multiparous women with higher education and who resided/delivered outside of Tbilisi were significantly less likely to experience PM. CONCLUSION: The risk of PM doubled among women with unattended pregnancies. Six percent of PM cases were attributable to unattended pregnancies. Targeting women with previous unattended pregnancies will likely reduce the PM rate in Georgia.

Recurrent disease after treatment for cervical intraepithelial neoplasia-The importance of a flawless definition of residual disease and length of follow-up.

OBJECTIVE: To evaluate adherence to national guidelines for follow-up, and assess residual and recurrent disease after treatment for cervical intraepithelial neoplasia grade 2 or worse (CIN2+). STUDY DESIGN: In a case-series design women aged 25-69 years treated for primary CIN2+ in 2006-2011 (n = 752) were followed through August 9, 2019 for residual or recurrent disease, i.e., CIN2+ diagnosed before or after, respectively, two consecutive, normal post-treatment cytology results. We used the Chi-Square test to assess predictive factors of adherence to post-treatment follow-up and residual disease, and survival analyses to assess the cumulative incidence of residual and recurrent disease. RESULTS: Strict adherence to post-treatment follow-up was low . However, 702 (95 %) women attended at least one post-treatment follow-up visit within the suggested time window. Forty-two women (5.6%) were diagnosed with residual disease, 38 (91 %) of whom were diagnosed within 2 years of treatment. Among the 637 (85 %) women with two consecutive, normal post-treatment cytology results, cumulative incidence of recurrent disease was 1.0 (95 % confidence interval [CI]: 0.2-1.8) and 2.5 (95 % CI: 1.2-3.8) per 100 women-years within 42 and 78 months of treatment, respectively. Three women with residual and two with recurrent disease were diagnosed with cervical cancer within 78 months of treatment. Women with not-free resection margins at treatment had a significantly increased risk of residual and recurrent disease. Using a 2-year definition for residual disease would misclassify 3 of 5 cancer cases as recurrent disease when they were true cases of residual disease. CONCLUSIONS: This study emphasizes the importance of properly distinguishing between residual and recurrent disease after treatment for CIN2 + . Many women with residual disease could benefit from an earlier colposcopy, cervical biopsy, or diagnostic conization during post-treatment follow-up in order to detect occult cervical cancer. The cumulative incidence of recurrent disease within 78 months of treatment was low.

Surgeon's experience and clinical outcome after retropubic tension-free vaginal tape-A case series.

INTRODUCTION: The retropubic tension-free vaginal tape procedure has been the preferred method for primary surgical treatment of stress and stress-dominant mixed urinary incontinence in women for more than 20 years. In this study, we assessed associations between surgeon's experience with the primary tension-free vaginal tape procedure and both perioperative complications and recurrence rates. MATERIAL AND METHODS: Using a consecutive case-series design, we assessed 596 patients treated with primary retropubic tension-free vaginal tape surgery performed by 18 surgeons from 1998 through 2012, with follow up through 2015 (maximum follow-up time: 10 years per patient). Data on perioperative complications and recurrence of stress urinary incontinence from medical records was transferred to a case report form. Surgeon's experience with the tension-free vaginal tape procedure was defined as number of such procedures performed as lead surgeon (1-19 ["beginners"], 20-49 and ≥50 procedures). All analyses were done with a 5% level of statistical significance. We applied the Chi-square test in the assessment of perioperative complications. The regression analyses of recurrence rate by number of tension-free vaginal tape procedures performed were restricted to the three surgeons who performed ≥50 procedures. RESULTS: We found a significantly higher rate of bladder perforations (P = .03) and a higher rate of urinary retentions among patients whose tension-free vaginal tape procedures were performed by "beginners" (P = .06). We observed a significant reduction in recurrence rates with increasing number of tension-free vaginal tape procedures for one surgeon (P = .03). CONCLUSIONS: Surgeon's experience with the tension-free vaginal tape procedure is associated with the risk of bladder perforation and urinary retention, and may be associated with the long-term effectiveness of the procedure.
