Polycystic ovary syndrome (PCOS) is a common metabolic problem in women of reproductive age. Evidence suggests pregnant women with PCOS may have a higher risk of the development of adverse pregnancy outcomes; however, the relationship between pre-pregnancy overweight/obesity and pregnancy outcomes in women with PCOS remains uncertain. We try to clarify the relationship between pre-pregnancy overweight/obesity and subsequent pregnancy outcomes. Therefore, we conducted this systematic review and meta-analysis. We used the databases obtained from the PubMed, Embase, Web of Science, and Cochrane databases, plus hand-searching, to examine the association between pre-pregnancy overweightness/obesity and pregnancy outcomes in women with PCOS from inception to 4 February 2022. A total of 16 cohort studies, including 14 retrospective cohort studies (n = 10,496) and another two prospective cohort studies (n = 818), contributed to a total of 11,314 women for analysis. The meta-analysis showed significantly increased odds of miscarriage rate in PCOS women whose pre-pregnancy body mass index (BMI) is above overweight (OR 1.71 [95% CI 1.38–2.11]) or obese (OR 2.00 [95% CI 1.38–2.90]) under a random effect model. The tests for subgroup difference indicated the increased risk was consistent, regardless which body mass index cut-off for overweight (24 or 25 kg/m2) or obesity (28 and 30 kg/m2) was used. With the same strategies, we found that pregnant women in the control group significantly increased live birth rate compared with those pregnant women with PCOS as well as pre-pregnancy overweight/obesity (OR 0.79 [95% CI 0.71–0.89], OR 0.78 [95% CI 0.67–0.91]). By contrast, we did not find any association between PCOS women with pre-pregnancy overweight/obesity and preterm birth. Based on the aforementioned findings, the main critical factor contributing to a worse pregnancy outcome may be an early fetal loss in these PCOS women with pre-pregnancy overweight/obesity. Since PCOS women with pre-pregnancy overweightness/obesity were associated with worse pregnancy outcomes, we supposed that weight reduction before attempting pregnancy in the PCOS women with pre-pregnancy overweightness/obesity may improve the subsequent pregnancy outcomes.
Preterm birth represents a great burden to the healthcare system, resulting in the consideration for the use of tocolytic therapy to provide a “better time” for delivery in order to buy time to accelerate fetal lung maturity, thereby minimizing prematurity-related morbidity and mortality. However, the benefits and potential side effects and risks of tocolytic treatment for preterm birth should be carefully balanced. Although many countries and societies provide guidelines or consensuses for the management for preterm birth, there is no standardized national guideline or consensus in Taiwan. As such, great heterogeneity is suspected in preterm labor management, contributing to the uncertainty of attitudes and practice patterns of obstetric specialists in Taiwan. This study attempts to understand the attitudes and practice patterns regarding tocolytic therapy in Taiwan. A paper-based survey was conducted at the 2020 Taiwan Society of Perinatology Conference on 8 December 2020, exploring how obstetric specialists would use tocolytics under nine different clinical scenarios, such as a short cervix, preterm labor, maintenance tocolysis, preterm premature rupture of membranes, etc. Three hundred ten specialists attended the conference, and 77 responded to the survey with a response rate of 24.8%. According to the survey, many of these specialists would prescribe tocolytics for less evidence-based indications, including 22% for abdominal tightness, 46% for a short cervix, 60% for maintenance tocolysis, and 89% for repeat tocolysis, with the preferred first line medication being ritodrine and nifedipine. We concluded that tocolysis is widely accepted and practiced in Taiwan. More research is needed to include Taiwan-specific economic and cultural factors as well as associated adverse effects and patients’ outcomes.
The incidence of lymph node (LN) involvement and its prognostic value based on radiological imaging in stage IIB cervical cancer (CC) remains unclear, and evidence regarding oncological outcomes of patients with stage IIB CC with LN metastases is limited. In this study we retrospectively reviewed the incidence and prognostic significance of pretreatment radiologic LN status in 72 patients with clinical stage IIB CC (FIGO 2009), with or without radiologic evidence of LN enlargement. An enlarged LN was defined as a diameter > 10 mm on CT/MRI. Progression-free survival (PFS) and overall survival (OS) were assessed. Radiologic LN enlargement of >10 mm was observed in 45.8% of patients with stage IIB CC. PFS (p = 0.0088) and OS rates (p = 0.0032) were significantly poorer in the LN group (n = 33) than in the non-LN group (n = 39). Univariate Cox analysis revealed that LN > 10 mm contributed to a higher rate of recurrence and mortality. In conclusion, nearly half of the patients with clinical stage IIB CC had enlarged LNs (>10 mm) identified during pretreatment radiologic evaluation, which negatively impacted prognosis. Our findings highlight the need to incorporate CT- or MRI-based LN assessment before treatment for stage IIB CC.
