For middle-class women laboring with the support of their male partner, the continuous presence of a doula during labor significantly decreased the likelihood of cesarean delivery and reduced the need for epidural analgesia. Women and their male partners were unequivocal in their positive opinions about laboring with the support of a doula.

Low Density Granulocytes (LDGs), which appear in the peripheral blood mononuclear cell layer of density-separated blood, are seen in cancer, sepsis, autoimmunity, and pregnancy. Their significance in ANCA vasculitis (AAV) is little understood. As these cells bear the autoantigens associated with this condition and have been found to undergo spontaneous NETosis in other diseases, we hypothesized that they were key drivers of vascular inflammation. We found that LDGs comprise a 3-fold higher fraction of total granulocytes in active vs. remission AAV and disease controls. They are heterogeneous, split between cells displaying mature (75%), and immature (25%) phenotypes. Surprisingly, LDGs (unlike normal density granulocytes) are hyporesponsive to anti-myeloperoxidase antibody stimulation, despite expressing myeloperoxidase on their surface. They are characterized by reduced CD16, CD88, and CD10 expression, higher LOX-1 expression and immature nuclear morphology. Reduced CD16 expression is like that observed in the LDG population in umbilical cord blood and in granulocytes of humanized mice treated with G-CSF. LDGs in AAV are thus a mixed population of mature and immature neutrophils. Their poor response to anti-MPO stimulation suggests that, rather than being a primary driver of AAV pathogenesis, LDGs display characteristics consistent with generic emergency granulopoiesis responders in the context of acute inflammation.

Background: Previous randomized controlled studies in several different settings demonstrated the positive effects of continuous labor support by an experienced woman (doula) for low-income women laboring without the support of family members. The objective of this randomized controlled trial was to examine the perinatal effects of doula support for nulliparous middle-income women accompanied by a male partner during labor and delivery. Methods: Nulliparous women in the third trimester of an uncomplicated pregnancy were enrolled at childbirth education classes in Cleveland, Ohio, from 1988 through 1992. Of the 686 prenatal women recruited, 420 met enrollment criteria and completed the intervention. For the 224 women randomly assigned to the experimental group, a doula arrived shortly after hospital admission and remained throughout labor and delivery. Doula support included close physical proximity, touch, and eye contact with the laboring woman, and teaching, reassurance, and encouragement of the woman and her male partner. Results: The doula group had a significantly lower cesarean delivery rate than the control group (13.4% vs 25.0%, p = 0.002), and fewer women in the doula group received epidural analgesia (64.7% vs 76.0%, p = 0.008). Among women with induced labor, those supported by a doula had a lower rate of cesarean delivery than those in the control group (12.5% vs 58.8%, p = 0.007). On questionnaires the day after delivery, 100 percent of couples with doula support rated their experience with the doula positively. Conclusions: For middle-class women laboring with the support of their male partner, the continuous presence of a doula during labor significantly decreased the likelihood of cesarean delivery and reduced the need for epidural analgesia. Women and their male partners were unequivocal in their positive opinions about laboring with the support of a doula.
