- ObjectiveTo evaluate microvascular function in women with previous hypertensive disorders of pregnancy (HDP).DesignRetrospective population-based cohort study.SettingLinkoping, Sweden.PopulationWomen aged 50-65 years, participating in the Swedish CArdioPulmonary bioImage Study (SCAPIS) at one site (Linkoping) 2016-18, who underwent microcirculatory assessment (N = 1222).MethodsForearm skin comprehensive microcirculatory assessment was performed with a PeriFlux PF6000 EPOS (Enhanced Perfusion and Oxygen Saturation) system measuring oxygen saturation and total speed resolved perfusion. Obstetric records were reviewed to identify women with previous HDP. Data on cardiovascular risk factors, comorbidities, medication, lifestyle, anthropometric data, and biochemical analyses were obtained from SCAPIS. The microcirculatory data were compared between women with and without previous HDP.Main outcome measuresSkin microcirculatory oxygen saturation and total speed resolved perfusion at baseline and post-ischaemic peak.ResultsWomen with previous pre-eclampsia displayed impaired post-ischaemic peak oxygen saturation compared with women with normotensive pregnancies (88%, interquartile range [IQR] 84-89% vs 91%, IQR 87-94%, p = 0.001) 6-30 years after pregnancy. The difference remained after multivariable adjustment (& beta; -2.69, 95% CI -4.93 to -0.45).ConclusionsThe findings reveal microvascular dysfunction at long-term follow up in women with previous pre-eclampsia and strengthen the possible role of endothelial dysfunction as a link to the increased risk of cardiovascular disease in women with HDP.

- BackgroundUniversal screening for postpartum depression is crucial for early detection, interventions and support. The aim of this study was to describe the proportion of, and explore risk factors for, women not being offered screening, as well as for declining an offer or not being screened due to any other unknown reason.MethodsSocioeconomic, obstetrical and neonatal data, extracted from the Swedish Pregnancy Registry, for 9,959 pregnancies recorded for the Östergötland county between 2016 and 2018 were linked to Edinburgh Postnatal Depression Scale (EPDS) screening results at 6–8 weeks postpartum, extracted from medical records. Risk factors were assessed using logistic regression models and with a nomogram for easy visualization.ResultsIn total, there were no recorded offers of EPDS screening in the medical records for 30.0% of women at the postpartum follow-up. Women born outside of Sweden and women reporting poor self-rated health were at increased risk of not being offered screening for postpartum depression.LimitationsThere is a possibility that women were offered screening or were screened, but this was incorrectly or never recorded in medical records.ConclusionsThe majority of women were offered screening for postpartum depression, but there is room for improvement in order to achieve universal screening. Awareness among healthcare providers of the risk factors for not screening might increase adherence to guidelines for universal screening. Overcoming barriers for screening and raising the topic of mental-health issues for postpartum women should be prioritized.

- To diagnose gestational diabetes mellitus (GDM), plasma glucose measurements during oral glucose tolerance test (OGTT) put high demands on the methods in terms of accuracy. The aim was to evaluate and compare diagnostic performance of a point-of-care test and a glucose hexokinase laboratory method. Using risk-based screening, 175 pregnant women were included. They underwent a 75 g OGTT in their 28th (median) week of gestation. Venous blood was collected in two different tubes. Plasma glucose was measured on Cobas c701 and in duplicates on AccuChek Inform II (both methods from Roche Diagnostics). Accuracy was assessed by participating in external control programs with reference method assigned values. The methods were compared for all samples (n = 512) by regression analysis; slope of 0.90 (95% CI: 0.89-0.92), intercept of 0.12 (95% CI: 0.011-0.22) and r(s) of 0.968. The average bias between AccuChek Inform II and Cobas c701 was -8%. The proportion of women diagnosed with GDM was 25% based on AccuChek Inform II versus 55% for Cobas c701. Results from the external control program showed a bias of approximately 5% for Cobas c701 and no significant bias for AccuChek Inform II. Cobas c701 showed a large bias both towards Accu-Chek Inform II and the reference method used in the external control program, clearly exceeding the desirable bias of <2.6%. The lack of accuracy has great implications on either over- or under-diagnosis of GDM.

- Introduction Identification of pregnant women suffering from depression or other mental disorders is a challenge for antenatal caregivers. The purpose of this case-control study was to describe mental disorders and the risk factors for mental disorders in women with depressive symptoms assessed with the Edinburgh Postnatal Depression Scale during the first trimester and to compare them with pregnant women without depressive symptoms. Material and methods In total, 2271 women answered the Edinburgh Postnatal Depression Scale at the first antenatal visit with a midwife. An Edinburgh Postnatal Depression Scale score of 13 or higher was considered to be screen-positive and these women were further assessed. Screen-negative pregnant women, matched for age and parity, were chosen as controls. Results In total, 149 (6.6%) women were found to be screen-positive. The majority (126, 85%) had at least one mental disorder or risk factor for mental disorder, such as depression (36.0%), anxiety (14.8%), or severe fear of childbirth (20.8%). The screen-positive women were more often smokers (16.1% vs 1.3%), unemployed (19.9% vs 1.3%), or on sick leave (25.3% vs 14.1%) during pregnancy and more often used selective serotonin reuptake inhibitor during pregnancy (14.2% vs 2.7%) compared with the screen-negative women (P<.001). Among the screen-negative women (n = 150) only three (2%) presented with symptoms of depression during pregnancy. Conclusions The Edinburgh Postnatal Depression Scale seems to be a valuable screening tool to detect depressive symptoms as well as other mental disorders during early pregnancy.

- Background Cervical cancer is a highly preventable disease. To not attend an organized cervical cancer screening program increases the risk for cervical dysplasia and cervical cancer. The aim was to investigate the participation rate in three different intervention groups for non- attendees in the Swedish national program for cervical screening. The participation in the recommended follow up, and the histology found were also examined. Method Population-based randomized control trial. It included10,614 women that had not participated in the cervical cancer screening programme during the last six years (ages 30-49) and the last eight years (ages 50-64) were randomised 1:1:1(telephone call from a midwife (offering the choice between a visit for a pap smear or an HPV self-sampling test); an HPV self-sampling test only; or the routine procedure with a yearly invitation). Results In the intention to treat analysis the participation rates were 25.5% (N = 803/3146) vs 34.1% (N = 1047/3068) and 7.0% (N = 250/3538) (p<0.001) for telephone, HPV self-test and control groups respectively. In the by protocol analysis including women that answered the phone call the participation rates were 31.7% (N = 565/1784) vs 26.1% (N = 788/3002) and 7.0% (N = 250/3538) (p<0.001) for telephone, HPV self-test and control groups. The corresponding results in the by protocol analysis including women that did not answer the phone call was 19.7% (N = 565/2870) vs 26.1% (N = 788/3002) and 7.0% (N = 250/3538) (p< 0.001). The majority of the women 63,4% (1131/1784) who answered the telephone wanted to participate either by booking a visit for pap smear (38,5%) or to be sent a HPV self- sampling test (24,9%) (p<0.001). Women who chose an HPV self-test were older and gave anxiety/ fear as a reason to decline participation, and they were also less likely to participate in the follow-up if found to be HPV-positive compared to the women who chose a Pap smear. The attendance to the recommended follow-up after abnormality was in total 87%. The non-attendees had a three or eight times higher risk of having a cytology result of HSIL or suspected SCC respectively, in the index sample compared to women screened as recommended (OR 3.3 CI 95% 1.9-5.2, OR 8.6 CI 1.6-30). A total of ten SCC and one adenocarcinoma were found in the histopathology results from the non-attendee group with a study intervention, while there was only one SCC in the non-attendee group without any study intervention (p = 0.02, OR 8.1 CI 95% 1.2-350). Conclusions Our study suggests, according to intention to treat analysis, that the best intervention to get as many non-attendees as possible to participate is to send an HPV self-sampling test together with an invitation letter. Almost 90% of women in the study with an abnormal index sample attended follow-up. This is high enough to indicate that interventions to increase the participation among non-attendees are meaningful.

- BackgroundStudent-led clinics (SLC) have been described, but not in gynecology. Gynecology is a subject typically covered in the last terms of medical training, however it includes few opportunities for students to tackle all phases of a consultation and a shortage of opportunities to perform gynecological examinations. Therefore, we started a student-led clinic for cervical cancer screening (SLC-CCS) in Linkoping, Sweden and aimed to evaluate students views on the progression of learning, the quality of the Papanicolaou (Pap) smear, and women s experiences of the visit, using mixed methodology.MethodsThe implementation of the SLC-CCS is described in detail. Students (n = 61) taking part in the SLC-CCS between January and May 2021 were invited to participate in a follow-up discussion (n = 24) focused around four themes: attitudes and expectations prior to participation, experiences of the patient encounter, organization of the placement, and reflections on and suggestions for further development of the placements. The group meetings were conducted in Swedish, recorded, transcribed verbatim and subjected to a qualitative, descriptive thematic analysis. Thematic analysis is considered an appropriate method of analysis for seeking to understand experiences, thoughts, or behaviors across a data set. The proportion of Pap smears lacking cells from the squamous epithelium during the study period was compared with data from the same clinic before the SLC-CCS started. A validated questionnaire on womens experience of the Pap smear visit was provided. Answers were compared between women who had the Pap smear taken by a student or a healthcare provider.ResultsThree different themes were generated: growing confidence in the clinical situation, embodied awareness of variation in anatomy, doubting accuracy of ones own performance. The percentage of Pap smears lacking cells from the squamous epithelium were equal (2%) during the study period compared to the period before the SLC-CCS started (p = 0.28). No difference was found in the satisfaction index between the women examined by a student, those examined by a healthcare provider, or women who did not know who the examiner was (p = 0.112).ConclusionsThe students expressed a growing confidence in the clinical situation and there was high satisfaction from the women. The quality of the Pap smears taken by the students was equal to the quality of those taken by the health care staff. All these findings indicate that high patient safety was maintained during this activity support the recommendation to include SLC-CCS as part of the medical training.

- Gestational diabetes mellitus (GDM) is a common complication with negative impacts on mother and child. The primary aim of this study was to examine whether plasma glucose cutoffs for GDM diagnosis based on venous sampling can be replaced by cutoffs based on capillary sampling. A prospective cross-sectional study was performed at an antenatal care clinic including 175 pregnant women undergoing an oral glucose tolerance test (OGTT). Duplicate samples were collected by capillary and venous puncture while fasting and 1 h and 2 h after an OGTT. Both samples were analyzed on Accu-Chek Inform II. The cutoffs for a GDM diagnosis using capillary samples were corrected from 5.1 to 5.3 mmol/L for the fasting sample, from 10.0 to 11.1 mmol/L for the 1 h sample, and from 8.5 to 9.4 mmol/L for the 2-h sample using half of the dataset. Applying these cutoffs to the remaining dataset resulted in a sensitivity, specificity, and accuracy of 85.0%, 95.0%, and 90.3%, respectively, with a positive predictive value (PPV) of 83%, an negative predictive value (NPV) of 96%, and a positive negative likelihood ratio (LHR) of 16.4 using capillary sampling for the GDM diagnosis at fasting and 2-h after. Corrected cutoffs and capillary samples can be used for the diagnosis of GDM with maintained diagnostic accuracy using Accu-Chek Inform II.

- IntroductionWomen with gestational diabetes mellitus (GDM) have higher rates of adverse perinatal outcomes compared with women without GDM, including an increased risk for having labor induced and for cesarean section. The findings from previous studies analyzing duration of labor in women with GDM are contradictory.The aim of the study was to evaluate the impact of GDM on time in spontaneous and induced active labor. Material and methodsThis was a population-based cohort study including 247 524 primiparous women who gave birth to a singleton fetus with cephalic presentation, >= 34(+0) (completed gestational weeks + additional days) between January 2014 and May 2020 in Sweden. Data was obtained from the Swedish Pregnancy Register. Time in active labor was compared between women with GDM and without GDM with a spontaneous labor onset or induction of labor using Kaplan Meier survival analysis and Cox regression analysis. ResultsWomen with GDM had significantly longer time in active labor, both with a spontaneous onset and induction of labor compared to women without GDM. Women with GDM had a decreased chance of vaginal delivery at a certain time-point compared to women without GDM, with adjusted hazard ratio of 0.92 (0.88-0.96) and 0.83 (0.76-0.90) for those with spontaneous onset and induction of labor, respectively. Women with GDM had increased risk for time in active labor >= 12 h both in spontaneous labor onset (adjusted odds ratio 1.14 [1.04-1.25]) and in induction of labor (adjusted odds ratio 1.55 [1.28-1.87]). ConclusionsWomen with GDM seem to spend a longer time in active labor, both in spontaneous and induced active labor compared to women without GDM. To be able to individualize care intrapartum, there is a need for more studies demonstrating the impact of hyperglycemia during pregnancy on outcomes during childbirth.

Hyperglycemia in pregnancy : diagnostics and duration of labor
- 2023

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Objectives: The overall aim of this thesis was to evaluate the impact of maternal hyperglycemia in pregnancy on the duration of active labor, to evaluate indications for cesarean section and further, to examine cut-offs for gestational diabetes mellitus diagnosis based on capillary sampling.Material and methods: Study I was a cross-sectional study on diagnostic accuracy performed at an antenatal care clinic at the University Hospital in Linköping, Sweden. The study included 175 women undergoing an oral glucose tolerance test (OGTT) and aimed to compare capillary and venous sampling in the diagnosis of gestational diabetes mellitus (GDM) using Accu-Chek Inform II.Studies II and III were population-based, nationwide, Swedish register studies using data from the Swedish Pregnancy Register (SPR). In these, 247 524 primiparous women who delivered a singleton fetus, ≥34+0 (completed gestational weeks + additional days) with a cephalic presentation between 1 January 2014 and 30 May 2020 and had their data available in the SPR were included. Time in active labor was compared between women with GDM and women without diabetes (study II) and between women with type 1 diabetes and women without diabetes (study III) using Kaplan- Meier survival analysis and Cox regression analysis.In study III, we also evaluated indications for elective and emergency cesarean section (CS) in women with type 1 diabetes and women without diabetes.Results: In study I, the cut-offs for a GDM diagnosis using capillary samples were corrected from 5.1 to 5.3 mmol/L for the fasting sample, from 10.0 to 11.1 mmol/L for the 1 h sample and from 8.5 to 9.4 mmol/L for the 2 h sample using half of the dataset. Applying these cut-offs to the remaining dataset resulted in a sensitivity, specificity and accuracy of 85.0%, 95.0% and 90.3% respectively, with a positive predictive value (PPV) of 83%, a negative predictive value (NPV) of 96% and a positive likelihood ratio (LHR) of 16.4 using capillary sampling for the GDM diagnosis at fasting and 2-h.In study II, women with GDM had a significantly longer time in active labor, both with a spontaneous onset and induction of labor compared to women without diabetes. Women with GDM also had a decreased chance of vaginal delivery at a certain time-point compared to women without diabetes, with an adjusted hazard ratio (aHR) of 0.92 (0.88- 0.96) and 0.83 (0.76-0.90) for those with spontaneous onset and induction of labor respectively. Women with GDM had an increased risk for time in active labor ≥12 h both in spontaneous labor onset (adjusted odds ratio (aOR) 1.14 (1.04-1.25)) and in induction of labor (aOR 1.55 (1.28-1.87)).Women with type 1 diabetes had a significantly longer time in active labor, both in spontaneous onset and induced labor compared to women without diabetes. They also had a decreased chance of vaginal delivery at a certain time-point compared to women without diabetes with an aHR of 0.65 (0.60-0.70). The total rate of CS was 34.6% in the group of women with type 1 diabetes and 9.5% in the group of women without diabetes (both elective and emergency CS). The most common indication for elective CS among women with type 1 diabetes was suspected macrosomia (50.4%) whereas the corresponding number was 8.7% among women without diabetes. For emergency CS, the most common indication was fetal distress in women with type 1 diabetes (31.9%) and the corresponding number in women without diabetes was 35.9%.Conclusions: Regarding the diagnosis of GDM, we propose that capillary fasting and 2-hour post-prandial glucose samples, analyzed using the Accu-Chek Inform II system, could be used for the diagnosis of GDM during pregnancy. This approach would involve the use of adjusted cut-off values and demonstrates an acceptable level of accuracy within an antenatal care setting. It is imperative to obtain duplicate samples in order to maintain adequate precision. Furthermore, it is advisable to continue with the OGTT when the fasting samples fall within the normal range, as this leads to a greater number of women receiving a GDM diagnosis.Regarding time in active labor, both women with GDM and type 1 diabetes seemed to spend a longer time in active labor and were less likely to have a vaginal delivery at any given time compared to their non-diabetic counterparts. In order to customize and individualize intrapartum care, it is imperative to conduct further investigations that illustrate the influence of hyperglycemia in pregnancy on the duration of active labor and on the outcomes during childbirth. In subsequent studies, it will be determined whether the observed difference in the duration of active labor, as indicated in the current studies, remains consistent when employing new definitions of active labor and labor progression.Suspected fetal macrosomia is the main reason for elective CS among women with type I diabetes and needs to be addressed further.

- Adverse pregnancy outcomes are recognized risk enhancers for cardiovascular disease, but the prevalence of subclinical coronary atherosclerosis after these conditions is unknown.To assess associations between history of adverse pregnancy outcomes and coronary artery disease assessed by coronary computed tomography angiography screening.Cross-sectional study of a population-based cohort of women in Sweden (n=10528) with 1 or more deliveries in 1973 or later, ascertained via the Swedish National Medical Birth Register, who subsequently participated in the Swedish Cardiopulmonary Bioimage Study at age 50 to 65 (median, 57.3) years in 2013-2018. Delivery data were prospectively collected.Adverse pregnancy outcomes, including preeclampsia, gestational hypertension, preterm delivery, small-for-gestational-age infant, and gestational diabetes. The reference category included women with no history of these exposures.Coronary computed tomography angiography indexes, including any coronary atherosclerosis, significant stenosis, noncalcified plaque, segment involvement score of 4 or greater, and coronary artery calcium score greater than 100.A median 29.6 (IQR, 25.0-34.9) years after first registered delivery, 18.9% of women had a history of adverse pregnancy outcomes, with specific pregnancy histories ranging from 1.4% (gestational diabetes) to 9.5% (preterm delivery). The prevalence of any coronary atherosclerosis in women with a history of any adverse pregnancy outcome was 32.1% (95% CI, 30.0%-34.2%), which was significantly higher (prevalence difference, 3.8% [95% CI, 1.6%-6.1%]; prevalence ratio, 1.14 [95% CI, 1.06-1.22]) compared with reference women. History of gestational hypertension and preeclampsia were both significantly associated with higher and similar prevalence of all outcome indexes. For preeclampsia, the highest prevalence difference was observed for any coronary atherosclerosis (prevalence difference, 8.0% [95% CI, 3.7%-12.3%]; prevalence ratio, 1.28 [95% CI, 1.14-1.45]), and the highest prevalence ratio was observed for significant stenosis (prevalence difference, 3.1% [95% CI, 1.1%-5.1%]; prevalence ratio, 2.46 [95% CI, 1.65-3.67]). In adjusted models, odds ratios for preeclampsia ranged from 1.31 (95% CI, 1.07-1.61) for any coronary atherosclerosis to 2.21 (95% CI, 1.42-3.44) for significant stenosis. Similar associations were observed for history of preeclampsia or gestational hypertension among women with low predicted cardiovascular risk.Among Swedish women undergoing coronary computed tomography angiography screening, there was a statistically significant association between history of adverse pregnancy outcomes and image-identified coronary artery disease, including among women estimated to be at low cardiovascular disease risk. Further research is needed to understand the clinical importance of these associations.
