Care and self-reported outcomes of care experienced by women with mental health problems in pregnancy: findings from a national survey

Background mental health problems in pregnancy and the postnatal period are relatively common and, in pregnancy, are associated with an increase in adverse outcome. It is recommended that all women are asked about their emotional and mental health and offered treatment if appropriate. Objectives to describe the care received by women self-identifying with mental health problems in pregnancy, and to describe the effects of support, advice and treatment on outcomes in the postnatal period. Design this study used cross-sectional survey data collected in 2014 which described women's experience of maternity care. Setting England Participants a random sample of women who had a live birth in January 2014. Measurements the questionnaire asked about sociodemographic characteristics, whether women were asked about emotional and mental health in pregnancy, support and treatment offered, about postnatal wellbeing, and questions relating to attachment to their baby. Descriptive statistics and logistic regression were used to examine the associations between mental health and outcomes taking account of sociodemographic characteristics. Findings the survey response rate was 47%. Women with antenatal mental health problems were significantly more worried at the prospect of labour and birth, had lower satisfaction with the experience of birth, worse postnatal mental health, and indications of poorer attachment to their baby. They received substantially more care than other women but they did not always view this positively. Support, advice and treatment for mental health problems had mixed effects. Conclusions this study describes the significant additional care provided to women self-identifying with mental health problems in pregnancy, the mixed effects of support, advice and treatment, and the poor perception of staff interaction among women with mental health problems. Implications for practice health care professionals may need additional training to effectively support women with mental health problems during the perinatal period

Psychosocial factors that mediate the association between mode of birth and maternal postnatal adjustment: findings from a population-based survey.

BACKGROUND: Mode of birth has been found to be associated with maternal postnatal adjustment with women who have Caesarean Sections (CS) thought to be at higher risk of emotional distress. However the relationship is complex and studies have demonstrated mixed findings. The aim of this study is to evaluate a model that explores the direct relationship between mode of birth and postnatal maternal adjustment at 3 months and indirect relationships through psychosocial variables. METHODS: A secondary analysis of a population-based survey conducted in England, UK in 2014. The analysis included primiparous women with singleton babies who provided information about mode of birth (n = 2139). RESULTS: Maternal postnatal adjustment, as measured by Maternal postnatal wellbeing and Satisfaction with care during labour and birth, varied by mode of birth. Women who had an unplanned CS had the poorest postnatal adjustment. Mode of birth was not associated with Maternal/infant sense of belonging. Four out of the five proposed mediation variables (Perceived control, Maternal expectation, Support in labour, How long until the mother held her baby), showed partial mediation of the relationship between mode of birth and both Maternal postnatal wellbeing and Satisfaction with care during labour and birth. The strongest mediator was Perceived control and the only variable not to show a significant mediation effect was Health of the infant at 3 months. CONCLUSIONS: Birth by unplanned, but not planned, caesarean section was associated with poorer maternal adjustment and instrumental birth was associated with lower maternal satisfaction with labour and birth. These relationships were found to be partially mediated by psychosocial variables. Psychosocial interventions in the perinatal period should be considered to optimise maternal postnatal adjustment

The Role of Cadmium and Nickel in Estrogen Receptor Signaling and Breast Cancer: Metalloestrogens or Not?

During the last half-century, incidences of breast cancer have increased globally. Various factors —genetic and environmental— have been implicated in the initiation and progression of this disease. One potential environmental risk factor that has not received a lot of attention is the exposure to heavy metals. While several mechanisms have been put forth describing how high concentrations of heavy metals play a role in carcinogenesis, it is unclear whether chronic, lowlevel exposure to certain heavy metals (i.e. cadmium and nickel), can directly result in the development and progression of cancer. Cadmium and nickel have been hypothesized to play a role in breast cancer development by acting as metalloestrogens— metals that bind to estrogen receptors and mimic the actions of estrogen. Since the lifetime exposure to estrogen is a wellestablished risk factor for breast cancer, anything that mimics its activity will likely contribute to the etiology of the disease. However, heavy metals, depending on their concentration, are capable of binding to a variety of proteins and may exert their toxicities by disrupting multiple cellular functions, complicating the analysis of whether heavy metal-induced carcinogenesis is mediated by the estrogen receptor. The purpose of this review is to discuss the various epidemiological, in vivo, and in vitro studies that show a link between the heavy metals, cadmium and nickel, and breast cancer development. We will particularly focus on the studies that test whether or not these two metals act as metalloestrogens in order to assess the strength of the data supporting this hypothesis

Mothers’ accounts of the impact on emotional wellbeing of organised peer support in pregnancy and early parenthood: a qualitative study

Background The transition to parenthood is a potentially vulnerable time for mothers’ mental health and approximately 9–21% of women experience depression and/or anxiety at this time. Many more experience sub-clinical symptoms of depression and anxiety, as well as stress, low self-esteem and a loss of confidence. Women’s emotional wellbeing is more at risk if they have little social support, a low income, are single parents or have a poor relationship with their partner. Peer support can comprise emotional, affirmational, informational and practical support; evidence of its impact on emotional wellbeing during pregnancy and afterwards is mixed. Methods This was a descriptive qualitative study, informed by phenomenological social psychology, exploring women’s experiences of the impact of organised peer support on their emotional wellbeing during pregnancy and in early parenthood. Semi-structured qualitative interviews were undertaken with women who had received peer support provided by ten projects in different parts of England, including both projects offering ‘mental health’ peer support and others offering more broadly-based peer support. The majority of participants were disadvantaged Black and ethnic minority women, including recent migrants. Interviews were audio-recorded and transcripts were analysed using inductive thematic analysis. Results 47 mothers were interviewed. Two key themes emerged: (1) ‘mothers’ self-identified emotional needs’, containing the subthemes ‘emotional distress’, ‘stressful circumstances’, ‘lack of social support’, and ‘unwilling to be open with professionals’; and (2) ‘how peer support affects mothers’, containing the subthemes ‘social connection’, ‘being heard’, ‘building confidence’, ‘empowerment’, ‘feeling valued’, ‘reducing stress through practical support’ and ‘the significance of “mental health” peer experiences’. Women described how peer support contributed to reducing their low mood and anxiety by overcoming feelings of isolation, disempowerment and stress, and increasing feelings of self-esteem, self-efficacy and parenting competence. Conclusion One-to-one peer support during pregnancy and after birth can have a number of interrelated positive impacts on the emotional wellbeing of mothers. Peer support is a promising and valued intervention, and may have particular salience for ethnic minority women, those who are recent migrants and women experiencing multiple disadvantages

Safety and Immunogenicity of an HIV Adenoviral Vector Boost after DNA Plasmid Vaccine Prime by Route of Administration: A Randomized Clinical Trial

In the development of HIV vaccines, improving immunogenicity while maintaining safety is critical. Route of administration can be an important factor.This multicenter, open-label, randomized trial, HVTN 069, compared routes of administration on safety and immunogenicity of a DNA vaccine prime given intramuscularly at 0, 1 and 2 months and a recombinant replication-defective adenovirus type 5 (rAd5) vaccine boost given at 6 months by intramuscular (IM), intradermal (ID), or subcutaneous (SC) route. Randomization was computer-generated by a central data management center; participants and staff were not blinded to group assignment. The outcomes were vaccine reactogenicity and humoral and cellular immunogenicity. Ninety healthy, HIV-1 uninfected adults in the US and Peru, aged 18-50 were enrolled and randomized. Due to the results of the Step Study, injections with rAd5 vaccine were halted; thus 61 received the booster dose of rAd5 vaccine (IM: 20; ID:21; SC:20). After the rAd5 boost, significant differences by study arm were found in severity of headache, pain and erythema/induration. Immune responses (binding and neutralizing antibodies, IFN-γ ELISpot HIV-specific responses and CD4+ and CD8+ T-cell responses by ICS) at four weeks after the rAd5 booster were not significantly different by administration route of the rAd5 vaccine boost (Binding antibody responses: IM: 66.7%; ID: 70.0%; SC: 77.8%; neutralizing antibody responses: IM: 11.1%; ID: 0.0%; SC 16.7%; ELISpot responses: IM: 46.7%; ID: 35.3%; SC: 44.4%; CD4+ T-cell responses: IM: 29.4%; ID: 20.0%; SC: 35.3%; CD8+ T-cell responses: IM: 29.4%; ID: 16.7%; SC: 50.0%.)This study was limited by the reduced sample size. The higher frequency of local reactions after ID and SC administration and the lack of sufficient evidence to show that there were any differences in immunogenicity by route of administration do not support changing route of administration for the rAd5 boost.ClinicalTrials.gov NCT00384787

'We knew it was a totally random thing': parents' experiences of being part of a trial

Background Studies exploring parents’ trial experiences generally relate to their understanding of the consent process and the development of researcher strategies to facilitate recruitment and retention. The aim was to better understand parents’ experience of being part of a trial at the time and their perceptions of trial participation in retrospect. Methods Data were collected in a number of ways: from recorded discussions between parents and clinicians about the MRI or ultrasound, in open-text responses to questionnaires and in qualitative interviews at 1 and 2 years after participation. Thematic analysis was undertaken using NVivo10. Results Key themes identified were ‘deciding to take part’, with subthemes associated with ‘benefitting self’, ‘benefitting others’ and ‘being prepared’; ‘the randomisation process’ with subthemes relating to ‘acceptance’ and ‘understanding’ and ‘actual engagement’ with subthemes of ‘practicalities’ and ‘care from responsive staff’. Conclusion Parents’ perspectives on the trial and the processes and information received reflect their understanding and experience of the trial and the value of parent-friendly information-giving about participation, randomisation and follow-up. The practical and logistical points raised confirm the key issues and parents’ need for sensitive care and support in the course of a trial. Looking back, almost all parents were positive about their experience and felt that the family had benefitted from participation in the trial and follow-up studies, even when the developmental outcomes were poor

Determinants of penetrance and variable expressivity in monogenic metabolic conditions across 77,184 exomes

Penetrance of variants in monogenic disease and clinical utility of common polygenic variation has not been well explored on a large-scale. Here, the authors use exome sequencing data from 77,184 individuals to generate penetrance estimates and assess the utility of polygenic variation in risk prediction of monogenic variants
