Cancer in pregnancy - The obstetrical management.

Cancer in pregnancy, defined as a cancer diagnosed during pregnancy, is a rare but severe condition presenting both clinical and ethical challenges. During the last two decades a paradigm shift has occurred towards recommending similar staging and treatment regimens of pregnant and non-pregnant cancer patients. This strategy is a result of an increasing number of reassuring reports on chemotherapy treatment in pregnancy after the first trimester. The management of cancer in pregnancy should be managed in a multidisciplinary team where staging, oncological treatment, social and mental care, timing of delivery, and follow-up of the infant should be planned. Due to the rarity, centralization is recommended to allow experience accumulation. Furthermore, national and international advisory boards are supportive when there is a lack of expertise.

Lack of an association between first-trimester concentration of mid-regional pro-atrial natriuretic peptide and risk of early-onset preeclampsia <34 weeks' gestation.

AIM: We examined the heart failure biomarker mid-regional pro-atrial natriuretic peptide during the first trimester of pregnancy in relation to early-onset preeclampsia <34 weeks. MATERIALS AND METHODS: This case-control study included 34 women with singleton pregnancies with a preeclampsia diagnosis and delivery before 34 weeks of gestation who had attended the routine first-trimester ultrasound scan at 11-13+6 weeks of gestation between August 2010 and October 2015 at the Copenhagen University Hospital Rigshospitalet, Denmark, and 91 uncomplicated singleton pregnancies matched by time of the routine first-trimester blood sampling at 8-13+6 weeks. Descriptive statistical analyses were performed for maternal characteristics and obstetric and medical history for the case versus the control group. Concentrations of mid-regional pro-atrial natriuretic peptide, placental growth factor, soluble fms-like tyrosine kinase-1, and pregnancy-associated plasma protein A between early-onset preeclampsia cases and the control group were compared using Students t-test and the Mann-Whitney U test. Biochemical marker concentrations were converted into multiples of the expected median values after adjustment for gestational age. RESULTS: Mid-regional pro-atrial natriuretic peptide levels were not significantly different between early-onset preeclampsia cases and the control group in the first trimester of pregnancy. As expected, both placental growth factor and pregnancy-associated plasma protein A levels were significantly lower in early-onset preeclampsia, whereas soluble fms-like tyrosine kinase-1 levels were not statistically significantly different. CONCLUSION: The maternal first-trimester concentration of mid-regional pro-atrial natriuretic peptide, a peptide with multiple biological functions including a relation to cardiovascular disease, was not significantly different in women with early-onset preeclampsia.

New expert advice on cancer in pregnancy.

Cancer in pregnancy is rare, and most physicians lack knowledge in handling pregnant cancer patients. This review summarises the present knowledge on this condition. In the Netherlands, an Advisory Board on Cancer in Pregnancy was established in 2012. The board supports Dutch physicians' decisions in the management of pregnant patients with cancer. In 2021 the International Advisory Board on Cancer in Pregnancy was established, and in continuation, the Danish Advisory Board on Cancer in Pregnancy (DABCIP) has now been founded. DABCIP consists of 22 members from 13 different medical disciplines.

Atypical severe intrauterine growth retardation and affected placental function after COVID-19 infection.

This case report describes an atypical progression of pregnancy in a woman who was infected with COVID-19 in her second trimester and initially presented with signs of absent foetal movements. The foetus was diagnosed with severe intrauterine growth restriction and abnormal foetal Doppler flows. The condition slowly improved over months, and the pregnancy was terminated with an acute caesarean section in gestational week 35. Placenta was tested negative for SARS-CoV-2-nucleocapsid. Four days old, the child was found COVID-19-positive, but remained asymptomatic. This case is a rare example considering the improvement of placental function over time.

Stable fetal hemodynamics measured by Doppler flow after initiation of anti-hypertensive treatment with methyldopa in pregnant women with diabetes.

AIM: To evaluate whether initiation of anti-hypertensive treatment with methyldopa affects fetal hemodynamics in women with pregestational diabetes. METHODS: Prospective study of unselected singleton pregnant women with diabetes (seven type 1 and two type 2 diabetes), normal blood pressure and kidney function at pregnancy booking. Methyldopa treatment was initiated at blood pressure >135/85 mmHg and/or urinary albumin excretion (UAE) >300 mg/g creatinine. Pulsatility indices (PI) of the uterine, umbilical, middle cerebral arteries before and 1 week after initiation of methyldopa treatment (250 mg three times daily) was performed and the cerebro-placental ratio (CPR) was calculated. RESULTS: Methyldopa treatment was initiated at median 249 (range 192-260) gestational days, mainly due to gestational hypertension (n = 7). Blood pressure declined from 142 (112-156)/92 (76-103) mmHg before to 129 (108-144)/82 (75-90) mmHg after initiation of methyldopa treatment (p = 0.11 and 0.04 for systolic and diastolic blood pressure, respectively). There were no significant changes in the umbilical artery PI (0.82 (0.72-1.40) versus 0.87 (0.64-0.95), p = 0.62) or CPR (1.94 (0.96-2.33) versus 1.78 (1.44-2.76), (p = 0.73). Gestational age was 265 (240-270) d. Apgar scores were normal. CONCLUSIONS: Stable Doppler flow velocity waveforms were documented after initiation of methyldopa treatment for pregnancy-induced hypertensive disorders in this cohort of pregnant women with pregestational diabetes.

[Cancer in pregnancy]. / Cancer under graviditeten.

Cancer in pregnancy occurs in about one in 1,000 pregnancies. Recent reports have shown that most treatment regimes in second and third trimester are safe for the mother and the child. This has led to a paradigm shift in treating pregnant women with cancer. The management of the pregnant woman should be in a multidisciplinary setting, and delivery should be postponed to avoid very preterm delivery and planned 2-3 weeks after the last chemotherapeutic treatment allowing both maternal and foetal bone marrow to recover.

[Chemotherapy in the second and third trimester of pregnancy is compatible with the delivery of a healthy infant]. / Kemoterapi i andet og tredje trimester er foreneligt medforløsning af et raskt barn

This case report describes the delay in diagnosis and treatment of a diffuse large B-cell lymphoma in pregnancy of a 27-year-old woman. Chemotherapy was initiated in week 21 of pregnancy - the tumour regressed and the foetus had linear growth. The patient had caesarean section in week 34, and after delivery she received high doses of methotrexate and obtained complete remission. The two-year-old infant had a normal development.

Clarifying the learning experiences of healthcare professionals with in situ and off-site simulation-based medical education: a qualitative study.

OBJECTIVE: To examine how the setting in in situ simulation (ISS) and off-site simulation (OSS) in simulation-based medical education affects the perceptions and learning experience of healthcare professionals. DESIGN: Qualitative study using focus groups and content analysis. PARTICIPANTS: Twenty-five healthcare professionals (obstetricians, midwives, auxiliary nurses, anaesthesiologists, a nurse anaesthetist and operating theatre nurse) participated in four focus groups and were recruited due to their exposure to either ISS or OSS in multidisciplinary obstetric emergencies in a randomised trial. SETTING: Departments of obstetrics and anaesthesia, Rigshospitalet, Copenhagen, Denmark. RESULTS: Initially participants preferred ISS, but this changed after the training when the simulation site became of less importance. There was a strong preference for simulation in authentic roles. These perceptions were independent of the ISS or OSS setting. Several positive and negative factors in simulation were identified, but these had no relation to the simulation setting. Participants from ISS and OSS generated a better understanding of and collaboration with the various health professionals. They also provided individual and team reflections on learning. ISS participants described more experiences that would involve organisational changes than the OSS participants did. CONCLUSIONS: Many psychological and sociological aspects related to the authenticity of the learning experience are important in simulation, but the physical setting of the simulation as an ISS and OSS is the least important. Based on these focus groups OSS can be used provided that all other authenticity elements are taken into consideration and respected. The only difference was that ISS had an organisational impact and ISS participants talked more about issues that would involve practical organisational changes. ISS and OSS participants did, however, go through similar individual and team learning experiences.

[Severe pre-eclampsia and fetal trisomy 13 in a multiparous woman]. / Svaer praeeklampsi og føtal trisomi 13 hos en flergangsfødende.

Preeclampsia (PE) is a common clinical syndrome often seen in nulliparae and a major cause of maternal and neonatal morbidity and mortality. Genetic predisposition and abnormal trophoblastic function may contribute to the pathophysiology of PE. The association between trisomy 13 and PE might be suggestive for a causative effect of some fetal genes encoded on chromosome 13, predisposing for the development of PE. We here report a case of severe PE in a multiparous woman carrying a trisomy 13 fetus.

Diabetic nephropathy and microalbuminuria in pregnant women with type 1 and type 2 diabetes: prevalence, antihypertensive strategy, and pregnancy outcome.

OBJECTIVE: To evaluate the prevalence of diabetic nephropathy and microalbuminuria in pregnant women with type 2 diabetes in comparison with type 1 diabetes and to describe pregnancy outcomes in these women following the same antihypertensive protocol. RESEARCH DESIGN AND METHODS: Among 220 women with type 2 diabetes and 445 women with type 1 diabetes giving birth from 2007-2012, 41 women had diabetic nephropathy (albumin-creatinine ratio ≥300 mg/g) or microalbuminuria (albumin-creatinine ratio 30-299 mg/g) in early pregnancy. Antihypertensive therapy was initiated if blood pressure ≥135/85 mmHg or albumin-creatinine ratio ≥300 mg/g. RESULTS: The prevalence of diabetic nephropathy was 2.3% (5 of 220) in women with type 2 diabetes and 2.5% (11 of 445) in women with type 1 diabetes (P = 1.00). The figures for microalbuminuria were 4.5 (10 of 220) vs. 3.4% (15 of 445) (P = 0.39). Baseline glycemic control was comparable between women with type 2 diabetes (n = 15) and type 1 diabetes (n = 26). Blood pressure at baseline was median 128 (range 100-164)/81 (68-91) vs. 132 (100-176)/80 (63-100) mmHg (not significant) and antihypertensive therapy in type 2 versus type 1 diabetes was used in 0 and 62%, respectively, at baseline, increasing to 33 and 96%, respectively, in late pregnancy. Pregnancy outcome was comparable regardless type of diabetes; gestational age at delivery: 259 days (221-276) vs. 257 (184-271) (P = 0.19); birth weight 3,304 g (1,278-3,914) vs. 2,850 (370-4,180) (P = 0.67). CONCLUSIONS: The prevalence of diabetic nephropathy and microalbuminuria in early pregnancy was similar in type 2 and type 1 diabetes. Antihypertensive therapy was used more frequently in type 1 diabetes. Pregnancy outcome was comparable regardless type of diabetes.
