Amaç: İn vitro fertilizasyon (İVF) ve embriyonik manipülasyonlar yoluyla gebe kalan kadınlarda hormon kullanımı, pulmoner hipertansiyon olasılığı da dahil olmak üzere yenidoğanların sağlığıyla ilgili endişeleri artırmıştır. Bu nedenle bu çalışma, term İVF yenidoğanlarında pulmoner arter basıncını değerlendirmeyi amaçlamıştır. Gereç ve Yöntemler: Bu prospektif kesitsel çalışma Mart 2013 ile Ekim 2017 arasında gerçekleştirilmiştir ve 160 İVF yenidoğanı (grup 1) 160 doğal yolla olan yenidoğanla (grup 2) karşılaştırmaktadır. Her iki gruptaki yenidoğanlar, gebelik ve yenidoğan yaşı açısından eşleştirilmiş sezaryen ile doğan yenidoğanlardı. Yenidoğanlar üç-yedi günlük idi, 37-39 hafta ve 6 günlük tam dönem gebelik yaşına sahipti ve yenidoğanların doğum ağırlığı normal sınırlarda (2500-4000 g) idi. Sistolik pulmoner arter basıncı (SPAB), triküspit yetersizlik jetinin pik akış hızını temel alan gerçek zamanlı ekokardiyografi kullanılarak tahmin edildi. Bulgular: İki grup arasındaki ortalama SPAB açısından anlamlı bir fark gözlendi (p<0,001). Her ne kadar gestasyonel yaşın SPAB'yi düşürücü etkisi grup 1'de daha fazla ve istatistiksel olarak anlamlı olsa da, doğumdan sonra PAB'de kademeli azalma bu grupta daha yavaş gözlenmiştir. Ayrıca, her iki grupta da gebelik yaşının SPAB'yi düşürücü etkisi yenidoğan yaşına göre daha belirgindi. Ayrıca, her iki grupta da SPAB ile yenidoğan ağırlığı arasında anlamlı bir ters korelasyon gözlendi; ancak bu korelasyonun grup 1'de daha kuvvetli olduğu görüldü. Sonuç: Çalışmamız, İVF'yi yenidoğanlarda pulmoner hipertansiyon insidansında artış ile ilişkili bulmuştur. Bu nedenle, İVF yenidoğanlarında pulmoner

IntroductionDespite a growing body of research on the risks of SARS-CoV-2 infection during pregnancy, there is continued controversy given heterogeneity in the quality and design of published studies.MethodsWe screened ongoing studies in our sequential, prospective meta-analysis. We pooled individual participant data to estimate the absolute and relative risk (RR) of adverse outcomes among pregnant women with SARS-CoV-2 infection, compared with confirmed negative pregnancies. We evaluated the risk of bias using a modified Newcastle-Ottawa Scale.ResultsWe screened 137 studies and included 12 studies in 12 countries involving 13 136 pregnant women.Pregnant women with SARS-CoV-2 infection—as compared with uninfected pregnant women—were at significantly increased risk of maternal mortality (10 studies; n=1490; RR 7.68, 95% CI 1.70 to 34.61); admission to intensive care unit (8 studies; n=6660; RR 3.81, 95% CI 2.03 to 7.17); receiving mechanical ventilation (7 studies; n=4887; RR 15.23, 95% CI 4.32 to 53.71); receiving any critical care (7 studies; n=4735; RR 5.48, 95% CI 2.57 to 11.72); and being diagnosed with pneumonia (6 studies; n=4573; RR 23.46, 95% CI 3.03 to 181.39) and thromboembolic disease (8 studies; n=5146; RR 5.50, 95% CI 1.12 to 27.12).Neonates born to women with SARS-CoV-2 infection were more likely to be admitted to a neonatal care unit after birth (7 studies; n=7637; RR 1.86, 95% CI 1.12 to 3.08); be born preterm (7 studies; n=6233; RR 1.71, 95% CI 1.28 to 2.29) or moderately preterm (7 studies; n=6071; RR 2.92, 95% CI 1.88 to 4.54); and to be born low birth weight (12 studies; n=11 930; RR 1.19, 95% CI 1.02 to 1.40). Infection was not linked to stillbirth. Studies were generally at low or moderate risk of bias.ConclusionsThis analysis indicates that SARS-CoV-2 infection at any time during pregnancy increases the risk of maternal death, severe maternal morbidities and neonatal morbidity, but not stillbirth or intrauterine growth restriction. As more data become available, we will update these findings per the published protocol.

ObjectiveWe aimed to investigate whether the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) could be utilized to screen for gestational diabetes mellitus (GDM).Subjects and methodsNLR and PLR were assessed by retrospective analysis of 762 healthy and pregnant women with GDM. The patients were stratified into four groups, as follows: GDM (n=144), impaired glucose tolerance (n=76), only screen positive (n=238), and control (n=304).ResultsThe leukocyte, neutrophil, and lymphocyte counts were significantly higher in the study groups compared with the control group (P=0.001; P<0.01). There were no statistically significant differences between the groups with respect to the NLR and PLR (P>0.05).ConclusionWe do not recommend that blood NLR and PLR can be used to screen for GDM. However, increase in the leukocyte count is an important marker for GDM as it provides evidence of subclinical inflammation.

Lung ultrasound (LUS) is an effective tool to detect and monitor patients infected with 2019 coronavirus disease (COVID-19). The use of LUS on pregnant women is an emerging trend, considering its effectiveness during the outbreak. Eight pregnant women with a diagnosis of COVID-19 confirmed by nasal/throat real-time reverse transcription polymerase chain reaction testing who underwent point-of-care LUS examinations after routine obstetric ultrasound are described. A routinely performed LUS examination revealed serious lung involvement in 7 cases: 2 were initially asymptomatic; 3 have chest computed tomography; 1 had initial negative real-time reverse transcription polymerase chain reaction results; and 1 had initial negative computed tomographic findings. Treatment for COVID-19 was either commenced or changed in 87.5% of the patients (n = 7 of 8) on LUS findings. Among patients with abnormal LUS findings, treatment was commenced in 5 patients (71.5%) and changed in 2 patients (28.5%). One normal and 7 abnormal LUS cases indicate the impact of routine LUS on the clinical outcome and treatment of pregnant women.
