- Paracetamol, otherwise known as acetaminophen, is the active ingredient in over 600 prescription and nonprescription analgesic and antipyretic medications. Worldwide and in the United States, more than 50% and 65% of pregnant women use acetaminophen, respectively. Currently, acetaminophen is considered to be of minimal risk and appropriate for use during pregnancy by the US Food and Drug Administration and European Medicines Agency. Despite this, there exists concern that environmental exposure to pharmaceuticals including acetaminophen during fetal life may contribute to the increased rates of neurological, urogenital, and reproductive disorders.This consensus statement aimed to provide an evidence-based summary of the literature relating to neurological, urogenital, and reproductive outcomes that have been associated with maternal and perinatal use of acetaminophen. This consensus statement was created by an international multidisciplinary group consisting of experts in neurology, obstetrics/gynecologists, pediatrics, epidemiology, toxicology, endocrinology, reproductive medicine, and neurodevelopment. A literature review was conducted for studies published between 1995 and 2020, including only those with acetaminophen as an independent exposure. There is a limitation in the existing epidemiological literature addressing these questions, and future efforts are required.This consensus statement and systematic review finds evidence of significant neurodevelopmental and reproductive adverse effects of acetaminophen prenatal exposure, particularly with long-term use. It is recommended by this document that acetaminophen be used by pregnant women cautiously at the lowest effective dose for the shortest possible time and longer or higher-dose use be discussed with a health professional. It is also advised that packaging display warning labels related to the evidence discussed here.

Tidskriftsartikel (refereegranskat)abstract
- A subtotal hysterectomy implies retaining the cervix. Women who undergo this procedure are more likely to present with persistent vaginal bleeding (PVB) after surgery. To prevent subsequent vaginal bleeding, intraoperative cervical treatment (electrosurgical cauterization or resection) has been recommended. However, there is insufficient evidence demonstrating the efficacy of this treatment. The aims of this retrospective register study were to (1) establish the prevalence of PVB 1 year after subtotal hysterectomy, (2) analyze the effect of intraoperative cervical treatment during the subtotal hysterectomy on the occurrence of PVB, and (3) assess the impact of PVB on the patients self-reported assessment of her medical condition and satisfaction with the hysterectomy 1 year after surgery. Data were obtained fromthe SwedishNational Register for Gynecological Surgery for a cohort of women who underwent subtotal hysterectomy for benign conditions between January 2004 and June 2016. Preoperative and perioperative forms were collected to obtain demographic and clinical data. The 1-year inquiry form was used to collect data on occurrence of PVB, rating of medical condition, and satisfaction with surgical results. Multivariate logistic regression analyses were used to assess outcome measures. The prevalence of PVB following subtotal hysterectomy was 18.6%. Intraoperative treatment of the cervix at the time of the subtotal hysterectomy did not affect the frequency of PVB; the adjusted odds ratio (aOR) was 1.48, with a 95% confidence interval (CI) of 0.93 to 2.37. Althoughmore than 90% of women were satisfied or very satisfied with the surgical results, those experiencing bleeding episodes 1 year after the subtotal hysterectomy were significantly less content with the result of the surgery (aOR, 0.42; 95% CI, 0.26-0.67). There was no difference in self-perception of the medical condition 1 year after the surgery between women with and without PVB; the aOR was 1.16 with a 95% CI of 0.33 to 4.12. These data show that nearly 2 in 10 women may expect PVB following subtotal hysterectomy and that intraoperative cervical treatment does not affect the prevalence of bleeding. Although more than 90% of patients are satisfied with the results of surgery, women with PVB are less content. When choosing hysterectomy technique, information on the risk of PVB may be important. Subtotal hysterectomy may not be an option for women not willing to accept this risk.

- The age at natural menopause (ANM) in the Western world ranges from 40 to 60 years, with an average onset of 51 years. The exact mechanisms underlying the timing of ANM are not completely understood. Both genetic and environmental factors are involved. The best-established environmental factor affecting ANM is smoking; menopause occurs 1 to 2 years earlier in smokers. In addition to genetic and environmental factors, chronic metabolic diseases may influence ANM. Some evidence suggests that diabetes may accelerate menopausal onset. With more women of childbearing age receiving a diagnosis of diabetes, it is important to examine the impact of diabetes on reproductive health. This study was designed to determine whether ANM occurs at an earlier age among women who have diabetes before menopause than in women without diabetes. Data were obtained from the European Prospective Investigation into Cancer and Nutrition (EPIC) study, a large multicenter prospective cohort study investigating the relationship between diet, lifestyle, and genetic factors and the incidence of cancer and other chronic diseases. A cohort of 519,978 men and women, mostly aged 27 to 70 years, were recruited primarily from the general population between 1992 and 2000. A total of 367,331 women participated in the EPIC study. After exclusions, 258,898 of these women met study inclusion criteria. Diabetes status at baseline and menopausal age were based on self-report and were obtained through questionnaires. Participants were asked if they had ever been diagnosed with diabetes and if so at what age. Associations of diabetes and age at diabetes diagnosis with ANM were estimated using time-dependent Cox regression analyses, with stratification by center and adjustments for age, smoking, reproductive, and known diabetes risk factors including smoking and with age from birth to menopause or censoring as the underlying time scale. Overall, there was no statistically significant lower risk of becoming menopausal among women with diabetes than women with no diabetes; the hazard ratio (HR) was 0.94, with a 95% confidence interval (CI) of 0.89 to 1.01. However, compared with women with no diabetes, women with diabetes before the age of 20 years had an earlier menopause (10-20 years [HR, 1.43; 95% CI, 1.02-2.01] and <10 years [HR, 1.59; 95% CI, 1.03-2.43]), whereas women with diabetes at age 50 years or older had a later menopause (HR, 0.81; 95% CI, 0.70-0.95). No association with ANM was found for diabetes onset between the ages 20 and 50 years. Strengths of the study include its large sample size and the measurement of a broad set of potential confounders. However, there were several limitations. First, results may have been underestimated because of survival bias. Second, the sequence of menopause and diabetes in women with a late age at diabetes is uncertain, as both events occur in a short period, and both diabetes and menopause status were based on self-report, not verified by medical records. Third, no distinction was made between types 1 and 2 diabetes. Although there is no overall association between diabetes and age at menopause, the data suggest that early-onset diabetes may accelerate menopause. The delaying effect of late-onset diabetes on ANM is not in agreement with other studies suggesting the opposite association.

- The rate of spontaneous pregnancies in women with Turner syndrome (TS) is low (2% to 5%). Oocyte donation is an option for these women and enables many to become pregnant. Some investigators question the use of pregnancy induction in TS because of the high risk for aortic dissection or other serious cardiac events. A cardiac evaluation is recommended before pregnancy is planned in TS. Among patients with TS who use their own oocytes to become pregnant, 45% suffered a miscarriage. The aim of this study was to assess pregnancy rate and outcome in a population of Swedish women with spontaneous pregnancies or who were induced using donated oocytes. Cytogenetic karyotype also was examined; mosaicism was defined as the presence of more than 5% 46, XX cells. The study subjects were 482 women with TS who had participated in a voluntary screening program conducted at Swedish Turner Centers. Among the 482 women with TS, 57 (12%) had pregnancies, including spontaneous pregnancies. The live-born rate was 67 of 124 (54%). The patient's own oocytes were used in 27 (47%) of the pregnancies and oocyte donation in 30 (53%) of pregnancies. Spontaneous pregnancies occurred in 23 of 57 women (40%) with TS. Most pregnancies using the patient's own oocytes occurred in those with 45, X/46, XX mosaic karyotype. The miscarriage rate was 26% after oocyte donation and 45% with the use of the patient's own oocytes. Five liveborns (7%) had birth defects or a serious illness; 4 of these were born after spontaneous pregnancies. Only 1 live-born had coarctation of the aorta.

- Preterm birth is associated with increased rates of neonatal and infant mortality. It has been hypothesized that gestational age at birth may also be associated with increased mortality rates in adulthood, but to date, no studies have demonstrated this relationship. This national cohort study investigated the association between gestational age at birth and mortality in young adulthood. Data obtained from the Swedish Birth Registry identified 678,528 individuals who were born as singletons between 1973 and 1979 and survived to age 1 year. Among this cohort, 674,820 were included in the final analysis. Of these, 27,979 (4.1%) born preterm (<37 weeks) were followed to age 29 to 36 years (up to 2008). The primary study outcome measures were all-cause and cause-specific mortality. Cox proportional hazards regression was used to estimate the association between gestational age at birth and mortality for 4 age categories: early childhood (age, 1-5 years), late childhood (age, 6-12 years), adolescence (age, 13-17 years), and young adulthood (age, 18-36 years). There were 7095 deaths reported in 20.8 million person-years of follow-up. A strong inverse association was found between gestational age at birth for 2 of the age categories and mortality among individuals still alive at the beginning of each age range. The adjusted hazard ratio [aHR] for each additional week of gestation in early childhood was 0.92 (95% confidence interval [CI], 0.89-0.94; P < 0.001). This inverse association disappeared in late childhood (aHR, 0.99; 95% CI, 0.95-1.03; P = 0.61) and adolescence (aHR, 0.99; 95% CI, 0.95-1.03; P = 0.64), and reappeared in young adulthood (aHR, 0.96; 95% CI, 0.94-0.97; P < 0.001). In young adulthood, the gestational age at birth was associated with mortality rates (per 1000 person-years) as follows: the aHR was 0.94 for 22 to 27 weeks, 0.86 for 28 to 33 weeks, 0.65 for 34 to 36 weeks, 0.46 for 37 to 42 weeks (full-term), and 0.54 for 43 or more weeks (P < 0.001 for all). Relative to individuals born full-term, preterm birth was associated with increased mortality in young adulthood even among individuals born late preterm (34-36 weeks); the aHR was 1.31, with a 95% CI of 1.13-1.50; P < 0.001). Moreover, gestational age at birth in young adulthood had the strongest inverse association with mortality from congenital anomalies, as well as respiratory, endocrine, and cardiovascular disorders, and it had no association with mortality from neurological disorders, cancer, or injury.

Tidskriftsartikel (refereegranskat)abstract
- In many high-income countries, severe perinatal trauma (SPT), affecting the anal sphincter muscle complex, has been on the rise over the last decade. However, effective strategies to prevent SPT are scarce. In randomized controlled trials, only perineal warm compresses and massage have shown benefit. Other cohort studies have shown that prevention models involving several components can decrease the occurrence of SPT, including a stepped-wedge design that reduced SPT from 3.3% to 3.0%. In Scandinavia, a preventive strategy called collegial assistance has been used to help prevent SPT. This strategy involves 2 mid-wives who assist the woman in the second stage of labor, with the second midwife primarily focused on preventing SPT. The aim of this study was to compare the rate of SPT in pregnancies managed by collegial assistance versus a single midwife. This Oneplus study was a randomized, controlled, unmasked trial, conducted at 5 obstetric units in Sweden between December 10, 2018, and March 21, 2020. Included were adult women with uncomplicated singleton pregnancies at >37 weeks of gestation, who were carrying their first child or having their first vaginal birth after cesarean delivery. Excluded were women who had multiple pregnancies, had intrauterine fetal demise, were undergoing a planned cesarean section, or were at <37 weeks' gestation. Women were randomly assigned to either the intervention group with 2 midwives in attendance during active second stage labor or standard care with 1 midwife. All midwives were asked to document the preventive methods used in case report forms. A total of 3750 women were included in the final analysis-with 1879 women receiving collegial assistance and 1871 women receiving standard care. Of the women who gave birth spontaneously, 1546 were in the intervention group and 1513 in the standard care group. Severe perinatal trauma occurred less frequently in the intervention group than the standard care group (3.9% vs 5.7%; odds ratio, 0.68; 95% confidence interval, 0.49-0.97; P = 0.025). In the intervention group, 0.2% had fourth-degree tears compared with 0.5% in the standard care group. The median time for collegial assistance was 15 minutes (interquartile range, 10-20 minutes). The use of perineal warm compresses was similar in the intervention group and standard care group (86.4% vs 85.7%, respectively). No differences were observed in birth positions, manual perineal protection, neonatal outcomes, or secondary maternal outcomes. In conclusion, the attendance of a second midwife dedicated to preventing SPT during the second stage of labor significantly reduced the risk of injury.

Obstetric Outcomes in Women With Turner Karyotype EDITORIAL COMMENT

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- There is concern over the high risk of cardiovascular complications, hypertensive disorders, and other adverse obstetric outcomes among pregnant women with Turner syndrome (TS). A diagnosis of TS is made in some women late in life or not at all. Spontaneous pregnancies are rare in women with TS and are associated with a high rate of complications, especially miscarriage. The use of assisted reproductive techniques is an option for these women; pregnancy and implantation rates after oocyte donation in women with TS seem to be comparable with those without TS who need this treatment. Few data are available on obstetric outcome in pregnant women with TS. The aim of this retrospective population-based cohort study was to compare maternal and neonatal outcomes among singleton pregnancies of women with and without TS. Data on births occurring between 1973 and 2007 from the Swedish Genetic Turner Register and the Swedish Medical Birth Register were cross-linked. Obstetric outcome in infants born to women with TS was compared with a reference group of 56,000 women from the general population. Mean gestational age and birth weight were adjusted for maternal age. Outcome in TS women with twins was described separately. A total of 115 women with TS gave birth to 208 children (202 singletons and 3 sets of twins) during the study period. The TS diagnosis was unknown in 52% of the women before the first delivery. Women in the TS group were older at the first delivery than women in the reference group; median age was 30 years and 26 years, respectively (P < 0.0001). There was a trend toward more women with TS having preeclampsia during their first pregnancy (6.3 vs. 3.0%; P = 0.07). One woman suffered from an aortic dissection during her second spontaneous pregnancy. Compared with the reference group, the median gestational age was shorter in children in the TS group (-6.4 days, P = 0.0067), and median birth weight was lower (-208 g, P = 0.001); however, no significant difference was found in median standard deviation scores for weight and length at birth. The rate of cesarean delivery was higher in the TS group than in the reference group (35.6% vs. 11.8%, respectively, P < 0.0001). There was no significant difference in birth defects between groups. These findings show that women with a TS karyotype have mostly favorable obstetric outcomes. Singletons of women with TS have a shorter gestational age but a similar size at birth. The data also show no difference in birth defects between women with and without TS.

Mechanisms and prevention of alloimmunization in pregnancy.

- Transfusion only occasionally gives rise to antibody production, because blood cells per se are not markedly immunogenic. However, the immunological changes that occur during pregnancy increase the risk of alloimmunization against red blood cells, platelets, and/or leukocytes. Fetal-maternal bleeding during pregnancy or in relation to delivery is the antigenic stimuli for immunization against red blood cells, whereas other mechanisms, such as trophoblast-derived microparticles, may also play a role in the production of antibodies against platelets. Antibody-mediated immune suppression has for 4 decades successfully been used for prevention of RhD immunization. Result from a mouse model of fetal and neonatal alloimmune thrombocytopenia (FNAIT) suggests that the same principle may be applied for the prevention of FNAIT. A European Union-funded consortium is presently in the process of developing a hyperimmune anti-human platelet antigen 1a (HPA-1a) immunoglobulin G. The idea is to prevent HPA-1a immunization by administering the drug to nonimmunized HPA-1a-negative women after delivery of an HPA-1a-positive child. The anti-HPA-1a will be purified from plasma collected from women who previously have given birth to a child with FNAIT caused by anti-HPA-1a. If the results of the planned phase III trial are favorable, it is possible that a product for prevention of FNAIT will be available within this decade.

- Statins effectively reduce levels of serum cholesterol and lower the risk of cardiovascular disease, but have limited effectiveness if stringent goals for serum low-density lipoprotein (LDL) cholesterol levels are not met or adverse effects develop, requiring a dose reduction or drug discontinuation. Previous studies have shown that thyroid hormone and some of its metabolites reduce levels of serum LDL cholesterol and have potentially favorable actions on other lipoproteins. The studies were discontinued because of reports of adverse effects on heart and bone, and possible deaths. In a recent report, eprotirome, a thyromimetic compound with minimal uptake in nonhepatic-tissues, was shown to reduce levels of serum total and LDL cholesterol and apolipoprotein B without apparent side effects in patients not receiving statin therapy. This randomized, placebo-controlled, double-blind, multicenter trial investigated the safety and efficacy of eprotirome in lowering the level of serum LDL cholesterol in patients with hypercholesterolemia who already were receiving simvastatin or atorvastatin. The aim of the study was to determine whether adding eprotirome to statin therapy would provide additional lipid-lowering actions without producing adverse extrahepatic thyromimetic effects. Patients were randomly assigned to receive daily oral doses of 25, 50, or 100 mcg of eprotirome or a placebo for 12 weeks. The primary study outcome was changes in serum LDL cholesterol. The potential adverse thyromimetic effects on the heart, bone, and pituitary were examined. Treatment of patients for 12 weeks already receiving statins with either placebo or eprotirome at a dose of 25, 50, or 100 mu g reduced the mean level of serum LDL cholesterol from 141 mg per deciliter (3.6 mmol per liter) at baseline to 127, 113, 99, and 94 mg per deciliter (3.3, 2.9, 2.6, and 2.4 mmol per liter), respectively; this represented a mean reduction from baseline of 7%, 22%, 28%, and 32%, respectively. Similar reductions were found in the secondary study outcomes, which included serum levels of apolipoprotein B, triglycerides, and Lp(a) lipoprotein. No evidence of adverse effects of eprotirome on the heart, bone, or pituitary was noted. Although reductions in serum levels of thyroxine occurred in some patients who received eprotirome, there were no changes in levels of thyrotropin or triiodothyronine. These findings demonstrate that the addition of eprotirome to statin therapy produces substantial further reductions in serum LDL cholesterol, non-high-density lipoprotein cholesterol, and apolipoprotein B. The drug appears to have an excellent safety profile.
