Comparison of labour and birth outcomes between nulliparous women who used epidural analgesia in labour and those who did not: A prospective cohort study

ObjectiveTo compare labour and birth outcomes between nulliparous women who used versus did not use intrapartum epidural analgesia.DesignProspective cohort study.SettingTwo maternity hospitals in Ireland.PopulationA total of 1221 nulliparous women who gave birth vaginally or by emergency caesarean section.MethodsMultinomial logistic regression was used to analyse categorical outcomes, with results presented as ratios of relative risks (RRR). For dichotomous outcomes we used logistic regression, with results presented as odds ratios (OR).Main outcome measuresMode of birth, IV syntocinon use, pyrexia (≥38 °C), antibiotic treatment, first stage labour ≥10 h, second stage labour ≥2 h, blood loss (≥500 mls, ≥1000 mls), perineal trauma. Neonatal outcomes included Apgar score ≥7 at 1 min and 5 min, admission to neonatal intensive care unit, and infant feeding method.ResultsWomen using EA were more likely to require a vacuum-assisted birth (RRR 3.35, p < 0.01) or forceps-assisted birth (RRR 11.69, p < 0.01). Exposure to EA was associated with significantly greater risk of ≥10 h first (OR 6.72, p = 0.01) and ≥2 h second (OR 2.25, p < 0.01) stage labour, increased likelihood of receiving IV syntocinon (OR 9.38, p < 0.01), antibiotics (OR 2.97, p < 0.01) and a greater probability of pyrexia (OR 10.26, p < 0.01). Women who used EA were half as likely to be breastfeeding at three months postpartum (OR 0.53, p < 0.01). No differences were observed between groups in neonatal outcomes.ConclusionsOur data shows significant associations between EA use and several intrapartum outcomes.     

Evaluation of an intervention supporting breastfeeding among late-preterm infants during in-hospital stay

BackgroundLate-preterm infants show lower breastfeeding rates when compared with term infants. Current practice is to keep them in low-risk wards where clinical guidelines to support breastfeeding are well established for term infants but can be insufficient for late-preterm.ObjectiveThe aim of this study was to evaluate an intervention supporting breastfeeding among late-preterm infants in a maternity service in the Basque Country, Spain.MethodsThe intervention was designed to promote parents’ education and involvement, provide a multidisciplinary approach and decision-making, and avoid separation of the mother-infant dyad. A quasi-experimental study was conducted with a control (n = 212) and an intervention group (n = 161). Data was collected from clinical records from November 2012 to January 2015. Feeding rate at discharge, breast-pump use, incidence of morbidities, infant weight loss and hospital stay length were compared between the two groups.ResultsInfants in the control group were 50.7% exclusive breastfeeding, 37.8% breastfeeding, and, 11.5% formula feeding at discharge, whereas in the intervention group, frequencies were 68.4%, 25.9%, and 5.7%, respectively (p = 0.002). Mothers in the intervention group were 2.66 times more likely to use the breast-pump after almost all or all feeds and 2.09 times more likely to exclusively breastfeed at discharge. There were no significant differences in morbidities and infant weight loss between groups. Hospital stay was longer for infants who required phototherapy in the intervention group (p = 0.009).ConclusionThe intervention resulted in a higher breastfeeding rate at discharge. Interventions aimed to provide specific support among late-pretem infants in maternity services are effective.

Healthy Barbs: Activism Confronts Mortality

Barbara Brenner, JD, was the Executive Director of Breast Cancer Action (BCA) from 1995–2010. Before that, she was a longtime activist in the anti-war movement and an attorney who, for most of her career, practiced public policy law. After she was diagnosed with breast cancer in 1993 at the age of 41, she took the helm of BCA. Under her leadership, the organization moved into a position of national advocacy—demanding research on the causes and prevention of breast cancer, including the role of industrial pollutants. Barbara started the “Think Before You Pink” campaign, encouraging people to question whether companies that display pink ribbons actually produce products that harm women's health or generate any funds to fight breast cancer. Her blog, “Healthy Barbs,” challenged readers to critique routine healthcare practices and policies. Barbara received numerous awards, including a Jefferson Award for Public Service in 2007, the Smith College Medal in 2012, and the ACLU-Northern California's Lola Hanzel Courageous Advocacy Award in 2012. Barbara had a recurrence of breast cancer in 1996. She died of complications associated with amyotrophic lateral sclerosis, ALS, on May 10, 2013.     

Effect of immediate and continuous mother–infant skin-to-skin contact on breastfeeding self-efficacy of primiparous women: A randomised control trial

ObjectiveTo evaluate the effect of mother–infant immediate skin-to-skin contact on primiparous mother's breastfeeding self-efficacy.Study designA randomised control trial.SettingsThe study was conducted in Omolbanin obstetrics hospital (large tertiary hospital), Mashhad, Iran.Participants114 18–35 year-old primiparous, Iranian, healthy and full term mothers who anticipated normal vaginal delivery and intended to breastfeed their babies.InterventionSkin-to-skin contact immediately after birth and then controlling breastfeeding self-efficacy at 28 days postpartum.Main outcome measureMaternal breastfeeding self-efficacy at 28 days postpartum and success in first breastfeeding and mean time of first breastfeeding initiation.ResultsA total of 92 mother–infant dyads (47 dyads in skin-to-skin care skin-to-skin contact group and 45 dyads in routine care group) were monitored and analysed. In skin-to-skin contact group, breastfeeding self-efficacy was 53.42 ± 8.57 SD as compared to 49.85 ± 5.50 SD in routine care group which is significantly higher in skin-to-skin contact group (p = 0.0003).Successful breastfeeding initiation rate was 56.6% in skin-to-skin contact group as compared to 35.6% in routine care group (p = 0.02).Time to initiate first feed was 21.98 ± 9.10 SD min in SSC group vs. 66.55 ± 20.76 min in routine care group (p < 0.001).ConclusionMother–infant immediate skin-to-skin contact is an easy and available method of enhancing maternal breastfeeding self-efficacy. High breastfeeding self-efficacy increases exclusive breastfeeding duration.     

Navigating infant feeding supports after migration: Perspectives of Arabic and Chinese mothers and health professionals in Australia

Optimal feeding practices can establish lifelong, transgenerational and global health benefits. Migration and cultural factors impact infant feeding practices and the support mothers receive for optimal infant feeding. This qualitative study explored support for infant feeding among Arabic and Chinese speaking migrant mothers in Australia.Semi-structured focus groups were conducted in language with 24 Arabic and 22 Chinese-Mandarin speaking migrant mothers with children under five years of age. Individual interviews were conducted in English with 20 health professionals working with Arabic or Chinese speaking migrant families. Data were thematically analysed using the framework method.Traditional family networks and trusted bi-cultural doctors were influential infant feeding supports for mothers. Health professionals perceived maternal and child health services to be poorly understood, and some mothers who accessed services felt they were not always culturally sensitive. Mothers sought additional information and support through online sources and peers. Both mothers and health professionals recognised the challenges of managing conflicting infant feeding advice and seeking best-practice support.The findings of this study highlight opportunities for health professionals to better support migrant mothers’ infant feeding practices, for example through engaging families and working with doctors. There is a need for greater cultural sensitivity within maternal and child health services and culturally relevant programs to support healthy infant feeding practices among migrant communities.
