First-trimester serum biomarkers in twin pregnancies and adverse obstetric outcomes-a single center cohort study.

PURPOSE: This study aimed to determine the association of first-trimester maternal serum biomarkers with preterm birth (PTB), fetal growth restriction (FGR) and hypertensive disorders of pregnancy (HDP) in twin pregnancies. METHODS: This is a retrospective cohort study of twin pregnancies followed at Maternidade Dr. Alfredo da Costa, Lisbon, Portugal, between January 2010 and December 2022. We included women who completed first-trimester screening in our unit and had ongoing pregnancies with two live fetuses, and delivered after 24 weeks. Maternal characteristics, pregnancy-associated plasma protein-A (PAPP-A) and ß-human chorionic gonadotropin (ß-hCG) levels were analyzed for different outcomes: small for gestational age (SGA), gestational hypertension (GH), early and late-onset pre-eclampsia (PE), as well as the composite outcome of PTB associated with FGR and/or HDP. Univariable, multivariable logistic regression analyses and receiver-operating characteristic curve were used. RESULTS: 466 twin pregnancies met the inclusion criteria. Overall, 185 (39.7%) pregnancies were affected by SGA < 5th percentile and/or HDP. PAPP-A demonstrated a linear association with gestational age at birth and mean birth weight. PAPP-A proved to be an independent risk factor for SGA and PTB (< 34 and < 36 weeks) related to FGR and/or HDP. None of the women with PAPP-A MoM > 90th percentile developed early-onset PE or PTB < 34 weeks. CONCLUSION: A high serum PAPP-A (> 90th percentile) ruled out early-onset PE and PTB < 34 weeks. Unless other major risk factors for hypertensive disorders are present, these women should not be considered candidates for aspirin prophylaxis. Nevertheless, close monitoring of all TwP for adverse obstetric outcomes is still recommended.

User satisfaction with an intrauterine system containing 52 mg levonorgestrel: a Portuguese study.

OBJECTIVE: To characterise patient satisfaction 6 and 12 months after insertion of a 52 mg levonorgestrel-releasing intrauterine system (LNG-IUS) in Portuguese women. STUDY DESIGN: A non-interventional and prospective study was conducted in Portuguese women of reproductive age who had Levosert® inserted. Two questionnaires (administered 6 and 12 months after 52 mg LNG-IUS insertion) were used to collect information on the patients' menstrual pattern, discontinuation rate, and satisfaction rate with Levosert®. RESULTS: A total of 102 women were enrolled, of which only 94 (92.2%) completed the study. Seven participants discontinued the use of the 52 mg LNG-IUS. At 6 and 12 months, 90.7% and 90.4% of participants, respectively, were either satisfied or very satisfied with the 52 mg LNG-IUS. At 6 and 12 months, 73.2% and 72.3% of participants, respectively, indicated that they were very likely to recommend the 52 mg LNG-IUS to a friend or family member. Most women (92.2%) continued to use the 52 mg LNG-IUS for the first year. The percentage of women who were 'much more satisfied' with Levosert® than with their previous contraceptive methods was 55.9% and 57.8% at 6 and 12 months, respectively, per questionnaire assessment. Satisfaction was associated with age (p = 0.004), amenorrhoea (p < 0.003) and absence of dysmenorrhoea (p = 0.003), but not with parity (p = 0.922). CONCLUSIONS: These data suggest that the continuation and satisfaction rates with Levosert® were very high, and that this system is well accepted among Portuguese women. Patient satisfaction was driven by a favourable bleeding pattern and absence of dysmenorrhoea.

Satisfaction with the 52 mg levonorgestrel­releasing intrauterine system was high among Portuguese women. Patient satisfaction was mainly driven by a favourable bleeding pattern and absence of dysmenorrhoea.

Outcomes in Pregnant Women with Valvular Heart Disease from Portuguese-Speaking African Countries Treated in Portugal through an International Agreement of Health Cooperation.

Aims: We performed a clinical audit of maternal and fetal outcomes in pregnant women with valvular heart disease (VHD) from Portuguese-speaking African countries who were transferred for their care, during a twenty-year period, through a memorandum of agreement of international cooperation. Methods and results: A retrospective analysis of 81 pregnancies in 45 patients with VHD (median age 24, interquartile range 22-29 years) from 2000 to 2020 was performed. The main outcome measures were maternal cardiovascular and fetal outcomes. History of rheumatic heart disease was present in 60 (74.1%) pregnancies. Most were in New York Heart Association (NYHA) functional class I or II; at the first evaluation, 35 (43.2%) were on cardiac medication and 49 (60.5%) were anticoagulated. Forty-eight pregnancies had at least one valvular prosthesis, including 38 mechanical heart valves. During pregnancy, deterioration in NYHA functional class occurred in 35 (42.0%), and eight (9.9%) patients required initiation or intensified cardiac medication. Mechanical valve thrombosis complicated four (4.9%) pregnancies, all cases on heparin, and resulted in one maternal death. Haemorrhagic complications happened in 7 (8.6%) anticoagulated patients, in the immediate postpartum or puerperal period. The 81 pregnancies resulted in 56 (69.1%) live births, while miscarriage and fetal malformations occurred in 19 (23.5%) and 12 (14.8%) pregnancies, respectively. In multivariate analysis, vitamin K antagonist therapy was the only independent predictor of an unsuccessful pregnancy (p = 0.048). Conclusion: In a high-income country, successful pregnancy was possible with low rate of maternal events in women with VHD transferred from five low-middle income countries in Africa. The use of anticoagulation with a vitamin K antagonist was associated with an unsuccessful pregnancy.
