Show moreBACKGROUND: Women with a BRCA1/2 pathogenic variant are advised to undergo premenopausal risk-reducing salpingo-oophorectomy after completion of childbearing, to reduce their risk of ovarian cancer. Several studies reported less sexual pleasure 1 to 3 years after a pre-menopausal oophorectomy. However, the long-term effects of premeno-pausal oophorectomy on sexual functioning are unknown.OBJECTIVE: This study aimed to study long-term sexual functioning in women at increased familial risk of breast or ovarian cancer who under-went a risk-reducing salpingo-oophorectomy either before the age of 46 years (premenopausal group) or after the age of 54 years (postmenopausal group). Subgroup analyses were performed in the premenopausal group, comparing early (before the age of 41 years) and later (at ages 41-45 years) premenopausal risk-reducing salpingo-oophorectomy.STUDY DESIGN: Between 2018 and 2021, 817 women with a high familial risk of breast or ovarian cancer from an ongoing cohort study were invited to participate in our study. Because of a large difference in age in the study between the premenopausal and postmenopausal salpingo-oophorectomy groups, we restricted the comparison of sexual func-tioning between the groups to 368 women who were 60 to 70 years old at completion of the questionnaire (226 in the premenopausal group and 142 in the postmenopausal group). In 496 women with a premenopausal risk -reducing salpingo-oophorectomy, we compared the sexual functioning between women in the early premenopausal group (n=151) and women in the later premenopausal group (n=345). Differences between groups were analyzed using multiple regression analyses, adjusting for current age, breast cancer history, use of hormone replacement therapy, body mass index, chronic medication use (yes or no), and body image. RESULTS: Mean times since risk-reducing salpingo-oophorectomy were 20.6 years in the premenopausal group and 10.6 years in the postmenopausal group (P<.001). The mean age at questionnaire completion was 62.7 years in the premenopausal group, compared with 67.0 years in the postmenopausal group (P<.001). Compared with 48.9% of women in the postmenopausal group, 47.4% of women in the pre-menopausal group were still sexually active (P=.80). Current sexual pleasure scores were the same for women in the premenopausal group and women in the postmenopausal group (mean pleasure score, 8.6; P=.99). However, women in the premenopausal group more often re-ported substantial discomfort than women in the postmenopausal group (35.6% vs 20.9%; P=.04). After adjusting for confounders, premeno-pausal risk-reducing salpingo-oophorectomy was associated with sub-stantially more discomfort during sexual intercourse than postmenopausal risk-reducing salpingo-oophorectomy (odds ratio, 3.1; 95% confidence interval, 1.04-9.4). Moreover, after premenopausal risk-reducing sal-pingo-oophorectomy, more severe complaints of vaginal dryness were observed (odds ratio, 2.6; 95% confidence interval, 1.4-4.7). Women with a risk-reducing salpingo-oophorectomy before the age of 41 years reported similar pleasure and discomfort scores as women with a risk -reducing salpingo-oophorectomy between ages 41 and 45 years.CONCLUSION: More than 15 years after premenopausal risk-reducing salpingo-oophorectomy, the proportion of sexually active women was com-parable with the proportion of sexually active women with a postmenopausal risk-reducing salpingo-oophorectomy.However, after a premenopausal risk -reducing salpingo-oophorectomy, women experienced more vaginal dryness and more often had substantial sexual discomfort during sexual intercourse. This did not lead to less pleasure with sexual activity. Show less

Show moreBACKGROUND: In monochorionic twin pregnancies, the fetuses share a single placenta. When this placenta is unequally shared, a discordant antenatal growth pattern ensues resulting in high rates of perinatal morbidity and mortality. Understanding placental pathophysiology is paramount in devising feasible antenatal management strategies. Unequal placental sharing is not the sole determinant of birthweight discordance as there is no one-to-one relationship with placental share discordance. Placental angioarchitecture, especially the presence of large bidirectional anastomoses, is thought to affect this relationship by allowing for a compensatory intertwin blood flow. OBJECTIVE: This study aimed to assess whether placental angioarchitecture can affect birthweight discordance in live-born monochorionic twins, the aim of our study was 2-fold: (1) to assess the relationship between birthweight discordance and placental share discordance and (2) to examine to what extent large bidirectional anastomoses can compensate for the effect of unequal placental sharing on birthweight discordance, with a subgroup analysis for umbilical artery Doppler flow patterns in cases with a birthweight discordance of >= 20%. STUDY DESIGN: This was a retrospective cohort study that included monochorionic twin pregnancies observed in our center between March 2002 and June 2021, in which twins with a birthweight discordance of >= 20% were classified according to umbilical artery Doppler flow patterns of the smaller twin. We excluded cases with twin-twin transfusion syndrome and twin anemia polycythemia sequence. Monochorionic placentas of live-born twins were injected with dye, and images were saved for computer measurements of placental sharing and the diameter of anastomoses. Univariate linear regressions of the relationship between placental share discordance and birthweight discordance (both calculated as larger weight or share- smaller weight or share/larger weight or sharex 100%) and the relationship between arterioarterial and venovenous diameters and birthweight ratio/placental territory ratio were performed. RESULTS: A total of 449 placentas were included in the analysis. Placental share discordance was positively correlated with birthweight discordance (b coefficient, 0.325; 95% confidence interval, 0.254-0.397; P<.0001). The arterioarterial diameter was negatively correlated with birthweight ratio/placental territory ratio (b coefficient, -0.041; 95% confidence interval, -0.059 to -0.023; P<.0001), meaning that an increase in arterioarterial diameter leads to less birthweight discordance than expected for the amount of placental share discordance. There was no relationship between venovenous diameter and birthweight ratio/placental territory ratio (b coefficient, -0.007; 95% confidence interval, -0.027 to 0.012; P=.473). CONCLUSION: Birthweight discordance in monochorionic twins was strongly associated with placental share discordance. Large arterioarterial anastomoses can mitigate the effect of unequal placental sharing. Show less

Show moreBACKGROUND: Children with fetal and neonatal alloimmune throm-bocytopenia face increased risk of intracranial hemorrhage potentially leading to developmental impairment. To prevent intracranial hemorrhage, pregnant women with alloantibodies against fetal platelets are often treated with intravenous immunoglobulin. Intravenous immunoglobulin seems effective in vastly reducing the risk of fetal or neonatal bleeding complications. However, information on long-term neurodevelopment of these children is lacking. OBJECTIVE: This study aimed to evaluate long-term neurodevelopmental outcome in children with fetal and neonatal alloimmune thrombocytopenia who were treated with intravenous immunoglobulin antenatally. STUDY DESIGN: An observational cohort study was performed, including children of mothers treated with intravenous immunoglobulin during pregnancy because a previous child was diagnosed with fetal and neonatal alloimmune thrombocytopenia. Children were invited for a follow-up assessment including standardized cognitive and neurologic tests. The parents were asked to complete a behavioral questionnaire and school performance reports. The primary outcome was severe neurodevelopmental impairment, defined as severe cognitive impairment (intelligence quotient <70), cerebral palsy with Gross Motor Function Classification System Level >= 3, bilateral blindness, and/or bilateral deafness (requiring amplification). The secondary outcome was mild to moderate neurodevelopmental impairment, defined as either mild to moderate cognitive impairment (intelligence quotient <85), cerebral palsy with Gross Motor Function Classification System Level <= 2, minor neurologic dysfunction, vision loss, and/or hearing loss.RESULTS: Between 2003 and 2017, 51 children were live-born after antenatal intravenous immunoglobulin treatment. One family moved abroad and was therefore not eligible for inclusion. In total, 82% (41/50) of the eligible cases were included for neurodevelopmental assessment at a median age of 9 years and 8 months. Severe neurodevelopmental impairment was not detected. The incidence of mild to moderate neurodevelopmental impairment was 14% (6/41; 95% confidence interval, 6% -29%). The children's mean cognitive score, behavioral scores, and academic achievement were not different from those observed in the Dutch norm groups. Neuroimaging was performed in 90% (37/41) of cases. Severe intracranial hemorrhage was diagnosed in 2 cases (5%), one antenatally before the start of intravenous immunoglobulin and the other case 1 day after birth. Both cases had a normal neurodevelopmental outcome. CONCLUSION: The risk of neurodevelopmental impairment in children whose mothers were treated for fetal and neonatal alloimmune thrombocytopenia with antenatal intravenous immunoglobulin is comparable to that reported in the general population.

Show moreBACKGROUND: Vulvar Paget disease is an extremely rare skin disorder, which is most common in postmenopausal women. Most vulvar Paget disease cases are noninvasive; however, it may be invasive or associated with an underlying vulvar or distant adenocarcinoma. The current treatment of choice for noninvasive vulvar Paget disease is wide local excision, which is challenging because of extensive intraepithelial spread and may cause severe morbidity. Recurrence rates are high, ranging from 15% to 70%, which emphasizes the need for new treatment options. Imiquimod, a topical immune response modifier, has been shown to be effective in a few studies and case reports, and is a promising new treatment modality.OBJECTIVE: To prospectively investigate the efficacy, safety, and effect on quality of life of a standardized treatment schedule with 5% imiquimod cream in patients with noninvasive vulvar Paget disease.STUDY DESIGN: The Paget Trial is a multicenter prospective observational clinical study including 7 tertiary referral hospitals in the Netherlands. A total of 24 patients with noninvasive vulvar Paget disease were treated with topical 5% imiquimod cream 3 times a week for 16 weeks. The primary efficacy outcome was the reduction in lesion size at 12 weeks after the end of treatment. Secondary outcomes were safety, clinical response after 1 year, and quality of life. Safety was assessed by evaluation of adverse events and tolerability of treatment. Quality of life was investigated with 3 questionnaires taken before, during, and after treatment.RESULTS: Data were available for 23 patients, 82.6% of whom responded to therapy. A complete response was reported in 12 patients (52.2%), and 7 patients (30.4%) had a partial response. A histologic complete response was observed in 10 of the 12 patients with a complete response. Patients experienced side effects such as fatigue (66.7%-70.9%) and headaches (16.7%-45.8%), and almost 80% needed painkillers during treatment. Eight patients (34.8%) adjusted the treatment protocol to 2 applications a week, and 3 patients (13.0%) stopped treatment because of side effects after 4 to 11 weeks. Treatment improved quality of life, whereas a slight, temporary negative impact was observed during treatment. Two patients with a complete response developed a recurrence within 1 year after treatment. Follow-up showed 6 patients with a noninvasive recurrence after a median of 31 months (14-46 months) after the end of treatment.CONCLUSION: Topical 5% imiquimod cream can be an effective and safe treatment alternative for noninvasive vulvar Paget disease, particularly when compared with treatment with surgical excision.

Show moreBackgroundThe field of obstetrics and gynecology requires complex decision-making and skills because of unexpected high-risk situations. These skills are influenced by alertness, reaction time, and concentration. Night shifts result in sleep deprivation, which might impair these functions, although it is still unclear to what extent.ObjectiveThis study aimed to investigate whether a night shift routinely impairs the obstetrics and gynecology consultants’ and residents’ fitness to perform and whether this reaches a critical limit compared with relevant frames of reference.Study DesignResidents (n=33) and consultants (n=46) in obstetrics and gynecology conducted multiple measurements (n=415) at precall, postcall, and noncall moments with the fitness to perform self-test. The self-test consists of an adaptive pursuit tracking task that is able to objectively measure alertness, reaction time, concentration, and hand-eye coordination and Visual Analog Scale tests to subjectively score alertness. The test is validated with a sociolegal reference of a 0.06% ethanol blood concentration (the peak level after 2 units of alcohol, the legal driving limit). This equals −1.37% on the objective score and −8.17 points on subjective alertness. Linear mixed models were used to analyze the difference within subjects over a night shift, integrating repeated measures over time.ResultsThe overnight objective difference between postcall and precall measurements was −0.62 (P<.05) for residents and 0.28 (P=NS) for consultants, both not exceeding the sociolegal reference as a group. Objective impairment exceeded the reference for 31% of the residents and 28% of the consultants. Subjective alertness decreased in residents (−18.26; P<.001) and consultants (−10.85; P<.001), both exceeding the reference. No residents had to continue work postcall versus 7.8% of the consultants. None of the consultants that had to continue work were in an objective critically impaired state.ConclusionThis study provides insight and awareness of individual performance after night shifts with clear frames of reference. The performance of residents is negatively and significantly affected by night shifts; therefore, a scheduled day off after a night shift is justified. Consultants showed no overall impairment; however, a quarter did exceed the alcohol limit reference after their night shift. If not logistically feasible to schedule a protected day off after a night shift, our group recommends safe shift scheduling, including options to transfer care after a demanding night shift to prevent working in a compromised state.

Show moreBACKGROUND: Infants with severe hemolytic disease of the fetus and newborn often require 1 or multiple intrauterine transfusions to treat fetal anemia. Intrauterine transfusions may have an inhibiting effect on fetal and neonatal erythropoiesis.OBJECTIVE: To quantify the effect of 1 or multiple intrauterine transfusions on the fetal erythropoiesis by assessing the fetal reticulocyte counts in a population with severe hemolytic disease of the fetus and newborn.STUDY DESIGN: This was an observational cohort study in infants admitted to the Leiden University Medical Center who received 1 or multiple intrauterine transfusions for hemolytic disease of the fetus and newborn caused by (Rh)D or Kell antibodies and were born between January 2005 and December 2018.RESULTS: A total of 235 patients were included, of whom 189 were patients with D-mediated hemolytic disease of the fetus and newborn and 46 with Kell-mediated hemolytic disease of the fetus and newborn. Absolute fetal reticulocyte count in D-mediated hemolytic disease of the fetus and newborn declined exponentially over the course of consecutive intrauterine transfusions, with a 62% decline after 1 intrauterine transfusion (95% confidence interval, 56-67). A similar exponential decline was observed in Kell-mediated hemolytic disease of the fetus and newborn, with 32% (95% confidence interval, 19-45) decline after 1 intrauterine transfusion. This decline was not associated with the varying gestational age at the time of the first intrauterine transfusion or the total number of intrauterine transfusions. The number of red blood cell transfusions for postnatal anemia was greater for infants with D and Kell-mediated hemolytic disease of the fetus and newborn with >2 intrauterine transfusions (median of 3 [interquartile range, 2-3] vs 2 [interquartile range, 1-3], P=.035, in D-mediated disease and median of 2 [interquartile range, 1-2] vs 1 [interquartile range, 1-1], P<.001, in Kell-mediated disease). Infants born after >2 intrauterine transfusions less often required exchange transfusion in D-mediated hemolytic disease of the fetus and newborn (19/89 [21%] vs 31/100 [31%], P=.039), compared with infants with 1-2 intrauterine transfusions.CONCLUSION: Treatment with intrauterine transfusions causes an exponential decrease in fetal reticulocyte counts in both D- and Kell-mediated hemolytic disease of the fetus and newborn. Suppression of the compensatory erythropoiesis leads to prolonged postnatal anemia and an increased requirement of red blood cell transfusions after birth. Show less
