Experience of fathers with babies admitted to neonatal care units: A review of the literature

There is a growing understanding of the role and place of men in maternity care generally and for fathers of babies in neonatal care in particular. This review offers a systematic narrative review on issues affecting fathers, whose babies are admitted to neonatal units. Twenty-seven papers in the review highlighted four key themes: stress & anxiety; information; gender roles and emotions

"His tummy's only tiny" - Scientific feeding advice versus women's knowledge. Women's experiences of feeding their late preterm babies.

OBJECTIVE: This paper reports on one element of a study exploring the experiences of women who are caring for late preterm baby/babies (LPBs) and focuses on their experiences of breastfeeding. DESIGN: As this study aimed to privilege women's experiences, a feminist approach was utilised, with individual qualitative interviews in two phases conducted with a purposefully selected sample of women who were caring for a late preterm baby or babies. Template Analysis linked to Birth Territory Theory (BTT) was used to identify key issues and experiences of women. SETTING AND PARTICIPANTS: Women (N = 24 to N = 14) were recruited from an NHS Trust Hospital in the South West region of England. FINDINGS: Infant feeding was planned with alarm clock precision. Babies, whether breast or formula fed, were subject to strict feeding guidelines/supplementation/volumes dictated by doctors and enforced by nurses and midwives and greatly impacted on women's experiences of caring. Women were powerless at times to influence feeding and regimes did not facilitate instinctive mother-care or enable babies to demonstrate innate feeding behaviours (such as rooting and early feeding cues). KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The current approach to caring for women and their late PTBs tends to result in feeding becoming a source of stress and anxiety for women, rather than a positive experience. To resolve this, staff caring for women who have LPBs should focus on supporting women to trust their instincts, and to guide them in developing confidence in their ability to read their babies' cues, rather than in focusing on strict regimes of feeding. This should include individualised consideration of whether supplementation is required in the early days

Powerless responsibility: A feminist study of women's experiences of caring for their late preterm babies.

PROBLEM: There is minimal research exploring women's experiences of caring for a late preterm baby. The emphasis in the literature is mostly baby centric. BACKGROUND: The number of babies born late preterm is rising and women's views are largely unknown. AIM: What are the experiences of women who are caring for a late preterm baby? METHODS: A feminist lens was the key philosophical underpinning. Semi-structured interviews were undertaken with 14 women. FINDINGS: Women who become mothers' of late preterm babies have a complex journey. It begins with separation, with babies being cared for in unfamiliar and highly technical environments where the perceived experts are healthcare professionals. Women's needs are side-lined, and they are required to care for their babies within parameters determined by others. Institutional and professional barriers to mothering/caring are numerous. DISCUSSION: Some of the women who were separated from their babies immediately after birth had difficulties conceiving themselves as mothers, and others faced restrictions when trying to access their babies. Women described care that was centred on their babies. They were allowed and expected to care for their babies, but only with 'powerless responsibility'. Many women appeared to be excluded from decisions and were not always provided with full information about their babies. CONCLUSION: Women whose babies are born late preterm would benefit from greater consideration in relation to their needs, rather than the focus being almost exclusively on their babies

Association studies of up to 1.2 million individuals yield new insights into the genetic etiology of tobacco and alcohol use

Tobacco and alcohol use are leading causes of mortality that influence risk for many complex diseases and disorders 1 . They are heritable 2,3 and etiologically related 4,5 behaviors that have been resistant to gene discovery efforts 6–11 . In sample sizes up to 1.2 million individuals, we discovered 566 genetic variants in 406 loci associated with multiple stages of tobacco use (initiation, cessation, and heaviness) as well as alcohol use, with 150 loci evidencing pleiotropic association. Smoking phenotypes were positively genetically correlated with many health conditions, whereas alcohol use was negatively correlated with these conditions, such that increased genetic risk for alcohol use is associated with lower disease risk. We report evidence for the involvement of many systems in tobacco and alcohol use, including genes involved in nicotinic, dopaminergic, and glutamatergic neurotransmission. The results provide a solid starting point to evaluate the effects of these loci in model organisms and more precise substance use measures

Genetic diversity fuels gene discovery for tobacco and alcohol use

Tobacco and alcohol use are heritable behaviours associated with 15% and 5.3% of worldwide deaths, respectively, due largely to broad increased risk for disease and injury(1-4). These substances are used across the globe, yet genome-wide association studies have focused largely on individuals of European ancestries(5). Here we leveraged global genetic diversity across 3.4 million individuals from four major clines of global ancestry (approximately 21% non-European) to power the discovery and fine-mapping of genomic loci associated with tobacco and alcohol use, to inform function of these loci via ancestry-aware transcriptome-wide association studies, and to evaluate the genetic architecture and predictive power of polygenic risk within and across populations. We found that increases in sample size and genetic diversity improved locus identification and fine-mapping resolution, and that a large majority of the 3,823 associated variants (from 2,143 loci) showed consistent effect sizes across ancestry dimensions. However, polygenic risk scores developed in one ancestry performed poorly in others, highlighting the continued need to increase sample sizes of diverse ancestries to realize any potential benefit of polygenic prediction.Peer reviewe

Genetic mechanisms of critical illness in COVID-19.

Host-mediated lung inflammation is present1, and drives mortality2, in the critical illness caused by coronavirus disease 2019 (COVID-19). Host genetic variants associated with critical illness may identify mechanistic targets for therapeutic development3. Here we report the results of the GenOMICC (Genetics Of Mortality In Critical Care) genome-wide association study in 2,244 critically ill patients with COVID-19 from 208 UK intensive care units. We have identified and replicated the following new genome-wide significant associations: on chromosome 12q24.13 (rs10735079, P = 1.65 × 10-8) in a gene cluster that encodes antiviral restriction enzyme activators (OAS1, OAS2 and OAS3); on chromosome 19p13.2 (rs74956615, P = 2.3 × 10-8) near the gene that encodes tyrosine kinase 2 (TYK2); on chromosome 19p13.3 (rs2109069, P = 3.98 ×  10-12) within the gene that encodes dipeptidyl peptidase 9 (DPP9); and on chromosome 21q22.1 (rs2236757, P = 4.99 × 10-8) in the interferon receptor gene IFNAR2. We identified potential targets for repurposing of licensed medications: using Mendelian randomization, we found evidence that low expression of IFNAR2, or high expression of TYK2, are associated with life-threatening disease; and transcriptome-wide association in lung tissue revealed that high expression of the monocyte-macrophage chemotactic receptor CCR2 is associated with severe COVID-19. Our results identify robust genetic signals relating to key host antiviral defence mechanisms and mediators of inflammatory organ damage in COVID-19. Both mechanisms may be amenable to targeted treatment with existing drugs. However, large-scale randomized clinical trials will be essential before any change to clinical practice
