The Maternal Age Cut-Off for an Increase in Composite Adverse Outcomes.

OBJECTIVE: To investigate whether there is a specific maternal age cut-off at which there is an increase in maternal and neonatal adverse outcomes. METHODS: A retrospective study comparing maternal and neonatal outcomes between nulliparous women of different ages. The receiver operating characteristic model with the Youden index was used to find the best age cut-off using cesarean delivery (CD) and composite adverse outcomes. A multivariable logistic regression analysis was calculated after adjusting for smoking, induction of labour, epidural use, hypertensive disorders, gestational diabetes, and birth weight. RESULTS: The study included 11 343 nulliparous women. Age 28 years was found to be the cut-off age at which we found a significant increase in adverse outcomes. Women older than age 28 years had a higher risk of CD than women younger than 28 years (35.7% vs. 21.3%, P < 0.0001). They were also more likely to deliver prematurely (11.9% vs. 7.9%; P < 0.0001) and had higher rates hypertensive disorders (2.3% vs. 1.1%; P < 0.0001) and gestational diabetes mellitus (0.4% vs. 0.1%; P = 0.001). Furthermore, their babies were more likely to be growth restricted (1.1% vs. 0.3%; P < 0.0001). There were no differences in the rates of induction of labour or macrosomia. After adjusting for confounders, we found that women older than 28 years had higher risks of CD and adverse outcomes than younger women (aOR 1.9 [95% CI 1.744-2.1] and aOR 1.6 [95% CI 1.6-1.77], respectively). CONCLUSION: Increasing maternal age is independently associated with adverse maternal and neonatal outcomes with an age cut-off of 28 years. Women older than age 28 years are at higher risk for composite adverse outcomes than younger women.

Are we preventing the primary cesarean delivery at the second stage of labor following ACOG-SMFM new guidelines? Retrospective cohort study.

OBJECTIVE: In 2014, the American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal Fetal Medicine (SMFM) published an Obstetric Care Consensus for safe prevention of primary cesarean delivery. We aimed to assess whether these guidelines decreased the primary CD rate during the second stage of labor, in our department. DESIGN, SETTING, AND POPULATION: A retrospective cohort study of all women reaching the second stage of labor, at term, in a single university-affiliated medical center between2010 and 2017. METHODS: We compared maternal and neonatal outcomes over three year's periods:-pre-guidelines (2010-2013) vs. 2nd period - post-guidelines (2014-2017). THE MAIN OUTCOME MEASURES: CD rate at 2ndstage of labor. RESULTS: The study included 11,464 women. The CD rate in the 2nd stage of labor has increased significantly from 4% to 5.9% in the post-guidelines period (OR 1.48, 95% CI 1.16-1.89, p = .001). After a sub-analysis of specific subgroups, and adjustment for confounders, the increase was solely observed in nulliparous women (aOR 1.418, 95% CI 1.067-1.885, p = .016). Furthermore, increased odds for vaginal operative delivery were observed in the multiparous women in the post-guidelines period (2.7% vs. 4.1%, p = .046). CONCLUSIONS: The implementation of the new ACOG and SMFM guidelines was not associated with a change in the CD rate performed at the 2nd stage of labor in the whole study population. However, there was a rise in the CD rate performed at the 2nd stage in nulliparous women. Furthermore, there was an increase in operative deliveries in the whole study population, especially in multiparous women, without an apparent increase in other immediate adverse neonatal or maternal outcomes.

The impact of nurses' and physicians' shift change on obstetrical outcomes.

PURPOSE: To evaluate the effect around nurses' shift change and on-call physicians' shift change on obstetrical outcomes. METHODS: A retrospective study of women who had an attempt of labor in a single-medical center, January 2006-December 2017. Obstetrical outcomes were compared between the time around nurses' shift change (6:00-8:00, 14:00-16:00, and 22:00-00:00) to the rest of the day, and between the time around on-call physicians' shift change (6:00-8:00, 14:00-16:00) to the rest of the day. RESULTS: 32,861 women were included, 7826 deliveries occurred during nurses' shift-change, and 25,035 deliveries occurred during the rest of the day. The groups had similar general and obstetrical characteristics, with no statistical difference in cesarean delivery rate (10% vs. 9.8%, P = 0.45) (Table 1). Nurses' shift change had no measurable effect on obstetrical outcomes, including induction of labor, preterm labor, 5-min-Apgar score and cord pH value, except PPH which was less likely to occur during nurses' shift change period (3.8% vs. 4.4%, P = 0.045) (Table 2). From 32,861 deliveries, 5155 deliveries occurred during on-call physicians' shift-change, and 27,706 deliveries occurred during the rest of the day. Induction\augmentation of labor and epidural analgesia were less likely to happen during on-call physicians' shift change (34.4% vs. 38%, P < 0.0001, 59.6% vs. 61.8%, P = 0.003, respectively) (Table 3). The two groups had similar obstetrical outcomes, without statistical difference in cesarean delivery rate (10% vs. 9.8%, P = 0.63) (Table 4).

Group G streptococcal endocarditis-associated hemophagocytic syndrome.

We report the case of a 28-year-old previously healthy male who presented with a 1-week history of fever, headache, vomiting, and jaundice. Blood cultures were positive for group G streptococci and transesophageal echocardiography demonstrated vegetations on the aortic valve, leading to a definitive diagnosis of infective endocarditis. The combination of fever, splenomegaly, anemia, thrombocytopenia, hypertriglyceridemia, elevated ferritin level, low natural killer (NK) cell activity, and hemophagocytosis in bone marrow aspirate confirmed the diagnosis of hemophagocytic syndrome (hemophagocytic lymphohistiocytosis). Antibiotic treatment and intravenous immunoglobulins were administered and the patient made a full recovery.
