Current strategies for the assessment and treatment of recurrent pregnancy loss are discussed. This replaces the previous document, titled, "Evaluation and treatment of recurrent pregnancy loss: a committee opinion," last published in 2012.

Subchorionic hematoma (SCH) is a frequent cause of first-trimester bleeding, particularly in pregnancies conceived through assisted reproductive technologies (ART), and is associated with adverse pregnancy outcomes when persistent. Management is largely conservative, with limited targeted therapeutic options. This descriptive case series evaluated the effectiveness and safety of oral alpha-lipoic acid (ALA) as an adjunct therapy in three primigravida women with ART-conceived pregnancies complicated by persistent first-trimester SCH unresponsive to conventional management, including progesterone support and hemostatic agents. ALA was administered orally at a dose of 600 mg once daily, alongside continued standard therapy. Clinical symptoms and hematoma progression were monitored through serial transvaginal ultrasonography. All three patients experienced cessation of vaginal bleeding within four to seven days of initiating ALA therapy. Complete sonographic resolution of the hematoma was observed within two to four weeks in all cases. No maternal or fetal adverse effects were reported, and all pregnancies progressed uneventfully into the second trimester. These findings suggest that oral ALA may represent a safe and potentially effective adjunctive therapy for persistent first-trimester SCH in ART pregnancies, warranting further evaluation in larger prospective studies.

To identify preconception clinical and multi-omics factors associated with conception and early pregnancy loss in women with unexplained recurrent pregnancy loss (URPL). In this prospective cohort study, 149 women with URPL selected from 420 outpatients based on guideline-recommended criteria were enrolled between November 2024 and May 2025 and followed-up for 12 months. Preconception fasting plasma was analyzed for clinical biomarkers, untargeted metabolomics, and data-independent acquisition proteomics. Outcomes included conception, ongoing pregnancy beyond 12 weeks and early pregnancy loss before 12 weeks. Multivariable logistic regression was used to evaluate the associations of clinical and multi-omics factors with reproductive outcomes, adjusting for maternal age, body mass index, number of prior losses, and use of assisted reproductive technology. Of 149 women, 99 conceived (66.4%) during the follow-up. By 12 weeks of gestation, 67 (67.7%) had ongoing pregnancies and 32 (32.3%) experienced early pregnancy loss. Higher testosterone was associated with lower probability of conception (adjusted odds ratio [aOR] 0.50, 95% confidence interval [CI] 0.28-0.89, p = 0.019). Women who conceived showed higher levels of progesterone-related metabolites, including 17-hydroxyprogesterone (fold change, FC = 3.89), pregnanediol 3-O-glucuronide (FC = 2.37), and pregnanetriol 3α-O-β-D-glucuronide (FC = 2.39). Among women who conceived, higher prolactin was associated with higher odds of early pregnancy loss (aOR 1.09, 95% CI 1.01-1.18, p = 0.036), and anti-phosphatidylserine/prothrombin showed a borderline association (aOR 1.07, 95% CI 1.00-1.14, p = 0.052). Early pregnancy loss was characterized by lower bile acid-related metabolites and higher caffeine and methylxanthine metabolites. Proteomic analysis showed enrichment of bile acid biosynthetic process. After adjustment, higher 7α,12α-dihydroxy-3-oxocholest-4-en-27-oic acid was associated with lower odds of early pregnancy loss (aOR 0.64, 95% CI 0.44-0.95, p = 0.025). Higher testosterone was associated with lower odds of conception. Among women who conceived, early pregnancy loss was associated with higher prolactin, borderline higher anti-PS/PT, lower bile acid-related metabolites, and higher caffeine-related metabolites, with 7α,12α-dihydroxy-3-oxocholest-4-en-27-oic acid identified as an exploratory metabolomic candidate. These findings suggest that potential androgen-related biology, prolactin, non-criteria antiphospholipid antibodies, and bile acid metabolism may be associated with reproductive outcomes in URPL, warranting validation in independent cohorts.

This consensus aims to provide guidance for postpartum women and people, healthcare providers and exercise professionals on physical activity, sedentary behaviour and sleep throughout the first year postpartum. The development of this guideline followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology and the Appraisal of Guidelines for Research and Evaluation II instrument. The Guideline Consensus Panel consisted of representatives from key professional groups, researchers and methodological experts. Literature was retrieved through searches of 12 online databases, and articles on maternal physical activity, sedentary behaviour or sleep in the first year after childbirth were eligible for inclusion if they reported on any of 21 maternal or infant health outcomes, which were prioritised considering the preferences and values of postpartum individuals. There was no restriction on language, and all study designs were eligible except for case studies. The certainty of evidence was rated using GRADE. This evidence review produced seven systematic reviews, which informed this consensus statement. A Delphi process was conducted to identify relative contraindications to postpartum moderate-intensity to vigorous-intensity physical activity, which informed the development of the Get Active Questionnaire for Postpartum. Evidence to decision tables were developed, and feedback on the recommendations was solicited from end users (healthcare providers, exercise professionals, researchers, policy organisations and postpartum women and people). Adhering to these consensus recommendations for postpartum women and people is likely to result in large improvements in psychological well-being, as well as pelvic, musculoskeletal and cardiometabolic health, and reduced fatigue, while not experiencing adverse events (moderate certainty evidence). Most end users indicated that following these recommendations would be feasible, acceptable and equitable, and likely to require minimal resources from individual and health systems perspectives.
