Birth-Related Perineal Trauma in Low- and Middle-Income Countries: A Systematic Review and Meta-analysis.

Introduction Birth-related perineal trauma (BPT) is a common consequence of vaginal births. When poorly managed, BPT can result in increased morbidity and mortality due to infections, haemorrhage, and incontinence. This review aims to collect data on rates of BPT in low- and middle-income countries (LMICs), through a systematic review and meta-analysis. Methods The following databases were searched: Medline, Embase, Latin American and Caribbean Health Sciences Literature (LILACs), and the World Health Organization (WHO) regional databases, from 2004 to 2016. Cross-sectional data on the proportion of vaginal births that resulted in episiotomy, second degree tears or obstetric anal sphincter injuries (OASI) were extracted from studies carried out in LMICs by two independent reviewers. Estimates were meta-analysed using a random effects model; results were presented by type of BPT, parity, and mode of birth. Results Of the 1182 citations reviewed, 74 studies providing data on 334,054 births in 41 countries were included. Five studies reported outcomes of births in the community. In LMICs, the overall rates of BPT were 46% (95% CI 36-55%), 24% (95% CI 17-32%), and 1.4% (95% CI 1.2-1.7%) for episiotomies, second degree tears, and OASI, respectively. Studies were highly heterogeneous with respect to study design and population. The overall reporting quality was inadequate. Discussion Compared to high-income settings, episiotomy rates are high in LMIC medical facilities. There is an urgent need to improve reporting of BPT in LMICs particularly with regards to births taking in community settings.

A mixed methods study to understand perinatal mental healthcare referral decisions among midwives and health visitors in the UK.

Background: In the UK approximately half of women requiring perinatal mental health (PNMH) care do not receive treatment despite having routine contact with midwives (MWs) and health visitors (HVs). Limited research has been undertaken regarding MWs'/HVs' decision-making around referring women for secondary PNMH care. In particular, the impact that the level of local secondary PNMH services may have on MWs'/HVs' referral decisions is unexplored. Aim: To understand MWs'/HVs' decision-making in relation to referring women with identified PNMH problems, to identify barriers and facilitators to effective and timely referrals including any impact of the local secondary PNMH service provision. Methods: Participants were recruited from four National Health Service (NHS) Trusts in England, located across two geographical areas, that provided different types of PNMH services. One area had PNMH services that met National Institute for Health and Care Excellence (NICE) guidelines; the other area had no secondary PNMH services. A sequential mixed methods design was used: In-depth semi-structured interviews with practising MWs/HVs (n = 24) to explore their approach to PNMH referral decision-making, analysed using thematic analysis; Questionnaire offered to all practising MWs/HVs in the two geographical areas to measure factors that may impact on PNMH referral decision-making allowing for statistical comparisons to be made between the professional groups/geographical areas. Findings: Three themes were identified from the interviews that impacted on MWs'/HVs' PNMH referral decision-making: identifying need; education, skills and experience; and referral pathways.Questionnaire response rate 13.1% (n = 99). The most reported facilitators to referral decision-making were a trusted relationship between MWs/HVs and women and routine enquiry about women's mental health; the most reported barriers were stigma associated with mental ill-health and women's perceived fear of child removal. Conclusion: Fundamental to MWs'/HVs' decision-making was their perceived relationship between themselves and women. Although PNMH service provision is important for women to ensure they receive appropriate PNMH care, service provision appeared less important to MWs'/HVs' referral decision-making than how maternity/health visiting services were delivered. Further important factors to MWs/HVs were to the ability to provide continuity of carer with women allowing MWs/HVs to identify women who would benefit from referral for secondary PNMH care.

Fluid-Phase Endocytosis and Lysosomal Degradation of Bovine Lactoferrin in Lung Cells.

The iron-binding protein lactoferrin and the cell-penetrating peptides derived from its sequence utilise endocytosis to enter different cell types. The full-length protein has been extensively investigated as a potential therapeutic against a range of pathogenic bacteria, fungi, and viruses, including SARS-CoV-2. As a respiratory antiviral agent, several activity mechanisms have been demonstrated for lactoferrin, at the extracellular and plasma membrane levels, but as a protein that enters cells it may also have intracellular antiviral activity. Characterisation of lactoferrin's binding, endocytic traffic to lysosomes, or recycling endosomes for exocytosis is lacking, especially in lung cell models. Here, we use confocal microscopy, flow cytometry, and degradation assays to evaluate binding, internalisation, endocytic trafficking, and the intracellular fate of bovine lactoferrin in human lung A549 cells. In comparative studies with endocytic probes transferrin and dextran, we show that lactoferrin binds to negative charges on the cell surface and actively enters cells via fluid-phase endocytosis, in a receptor-independent manner. Once inside the cell, we show that it is trafficked to lysosomes where it undergoes degradation within two hours. These findings provide opportunities for investigating both lactoferrin and derived cell-penetrating peptides activities of targeting intracellular pathogens.

Early Postnatal Discharge for Infants: A Meta-analysis.

CONTEXT: Postnatal length of hospital stay has reduced internationally but evidence-based policies to support earlier discharge are lacking. OBJECTIVE: To determine the effects of early postnatal discharge on infant outcomes. DATA SOURCES: CENTRAL (Cochrane Central Register of Controlled Trials), Medline, Embase, Cumulative Index to Nursing and Allied Health Literature , and SCI (Science Citation Index) were searched through to January 15, 2018. STUDY SELECTION: Studies reporting infant outcomes with early postnatal discharge versus standard discharge were included if they met Effective Practice and Organisation of Care study design criteria. DATA EXTRACTION: Two authors independently assessed eligibility and extracted data, resolving disagreements by consensus. Data from interrupted time series (ITS) studies were extracted and reanalyzed in meta-analyses. Meta-analyses of randomized controlled trials (RCTs) used random effects models. RESULTS: Of 9298 studies, 15 met the inclusion criteria. RCT meta-analyses revealed that infants discharged <48 hours after vaginal birth and <96 hours after cesarean birth were more likely to be readmitted to the hospital within 28 days compared to standard discharge (risk ratio: 1.70; 95% confidence interval [CI] 1.34 to 2.15). ITS meta-analyses revealed a reduction in the proportion of infants readmitted within 28 days after minimum postnatal stay policies and legislation were introduced (change in slope: -0.62; 95% CI -1.83 to 0.60), with increasing impact in the first and second years (effect estimate: -4.27 [95% CI -7.91 to -0.63] and -6.23 [95% CI -10.15 to -2.32]). LIMITATIONS: Withdrawals and crossover limited the value of RCTs in this context but not ITS evidence. CONCLUSIONS: Infants discharged early after birth were more likely to be admitted within 28 days. The introduction of postnatal minimum length of stay policies was associated with a long-term reduction in neonatal hospital readmission rates.

Synthetic social support: Theorizing lay health worker interventions.

Levels of social support are strongly associated with health outcomes and inequalities. The use of lay health workers (LHWs) has been suggested by policy makers across the world as an intervention to identify risks to health and to promote health, particularly in disadvantaged communities. However, there have been few attempts to theorize the work undertaken by LHWs to understand how interventions work. In this article, the authors present the concept of 'synthetic socialsupport' and distinguish it from the work of health professionals or the spontaneous social support received from friends and family. The authors provide new empirical data to illustrate the concept based on qualitative, observational research, using a novel shadowing method involving clinical and non-clinical researchers, on the everyday work of 'pregnancy outreach workers' (POWs) in Birmingham, UK. The service was being evaluated as part of a randomized controlled trial. These LHWs provided instrumental, informational, emotional and appraisal support to the women they worked with, which are all key components of social support. The social support was 'synthetic' because it was distinct from the support embedded in spontaneous social networks: it was non-reciprocal; it was offered on a strictly time-limited basis; the LHWs were accountable for the relationship, and the social networks produced were targeted rather than spontaneous. The latter two qualities of this synthetic form of social support may have benefits over spontaneous networks by improving the opportunities for the cultivation of new relationships (both strong and weak ties) outside the women's existing spontaneous networks that can have a positive impact on them and by offering a reliable source of health information and support in a chaotic environment. The concept of SSS can help inform policy makers about how deploying lay workers may enable them to achieve desired outcomes, specify their programme theories and evaluate accordingly.

Evaluation of a bespoke training to increase uptake by midwifery teams of NICE Guidance for membrane sweeping to reduce induction of labour: a stepped wedge cluster randomised design.

BACKGROUND: National guidance recommends pregnant women are offered membrane sweeping at term to reduce induction of labour. Local audit suggested this was not being undertaken routinely across two maternity units in the West Midlands, UK between March and November 2012. METHODS: Bespoke training session for midwifery teams (nine community and one antenatal clinic) was developed to address identified barriers to encourage offer of membrane sweeping, together with an information leaflet for women and appointment of a champion within each team. The timing of training session on membrane sweeping to ten midwifery teams was randomly allocated using a stepped wedge cluster randomised design. All women who gave birth in the Trusts after 39 + 3/40 weeks gestation within the study time period were eligible. Relevant anonymised data were extracted from maternity notes for three months before and after training. Data were analysed using a generalised linear mixed model, allowing for clustering and adjusting for temporal effects. Primary outcomes were number of women offered and accepting membrane sweeping and average number of sweeps per woman. Sub-group comparisons were undertaken for adherence to Trust guidance and potential influence of pre-specified maternal characteristics. Data included whether sweeping was offered but declined and no record of membrane sweeping. RESULTS: Training was given to all teams as planned. Analyses included data from 2787 of the 2864 (97%) eligible low-risk women over 39 + 4 weeks pregnant. Characteristics of the women were similar before and after training. No evidence of difference in proportion of women being offered and accepting membrane sweeping (44.4% before training versus 46.8% after training (adjusted relative risk [aRR] = 0.90, 95% confidence interval [CI] = 0.71-1.13), nor in average number of sweeps per woman (0.603 versus 0.627, aRR = 0.83, 95% CI = 0.67-1.01). No differences in any secondary outcomes nor influence of maternal characteristics were demonstrated. The midwives evaluated training positively. CONCLUSIONS: This stepped wedge cluster trial enabled randomised evaluation within a natural roll-out and demonstrates the importance of robust evaluation in circumstances in which it is rarely undertaken. While the midwives evaluated the training positively, it did not appear to change practice. TRIALS REGISTRATION: ISRCTN14300475 . Registered on 23 August 2016.

Lay support for pregnant women with social risk: a randomised controlled trial.

OBJECTIVES: We sought evidence of effectiveness of lay support to improve maternal and child outcomes in disadvantaged families. DESIGN: Prospective, pragmatic, individually randomised controlled trial. SETTING: 3 Maternity Trusts in West Midlands, UK. PARTICIPANTS: Following routine midwife systematic assessment of social risk factors, 1324 nulliparous women were assigned, using telephone randomisation, to standard maternity care, or addition of referral to a Pregnancy Outreach Worker (POW) service. Those under 16 years and teenagers recruited to the Family Nurse Partnership trial were excluded. INTERVENTIONS: POWs were trained to provide individual support and case management for the women including home visiting from randomisation to 6 weeks after birth. Standard maternity care (control) included provision for referring women with social risk factors to specialist midwifery services, available to both arms. MAIN OUTCOME MEASURES: Primary outcomes were antenatal visits attended and Edinburgh Postnatal Depression Scale (EPDS) 8-12 weeks postpartum. Prespecified, powered, subgroup comparison was among women with 2 or more social risks. Secondary outcomes included maternal and neonatal birth outcomes; maternal self-efficacy, and mother-to-infant bonding at 8-12 weeks; child development assessment at 6 weeks, breastfeeding at 6 weeks, and immunisation uptake at 4 months, all collected from routine child health systems. RESULTS: Antenatal attendances were high in the standard care control and did not increase further with addition of the POW intervention (10.1 vs 10.1 (mean difference; MD) -0.00, 95% CI (95% CI -0.37 to 0.37)). In the powered subgroup of women with 2 or more social risk factors, mean EPDS (MD -0.79 (95% CI -1.56 to -0.02) was significantly better, although for all women recruited, no significant differences were seen (MD -0.59 (95% CI -1.24 to 0.06). Mother-to-infant bonding was significantly better in the intervention group for all women (MD -0.30 (95% CI -0.61 to -0.00) p=0.05), and there were no differences in other secondary outcomes. CONCLUSIONS: This trial demonstrates differences in depressive symptomatology with addition of the POW service in the powered subgroup of women with 2 or more social risk factors. Addition to existing evidence indicates benefit from lay interventions in preventing postnatal depression. This finding is important for women and their families given the known effect of maternal depression on longer term childhood outcomes. TRIAL REGISTRATION NUMBER: ISRCTN35027323; Results.
