Multi-Omics Data Integration Reveals Sex-Dependent Hippocampal Programming by Maternal High-Fat Diet during Lactation in Adult Mouse Offspring. Nutrients 2023; 15:4691.

Abstract
Early-life exposure to high-fat diets (HF) can program metabolic and cognitive alterations in adult offspring. Although the hippocampus plays a crucial role in memory and metabolic homeostasis, few studies have reported the impact of maternal HF on this structure. We assessed the effects of maternal HF during lactation on physiological, metabolic, and cognitive parameters in young adult offspring mice. To identify early-programming mechanisms in the hippocampus, we developed a multi-omics strategy in male and female offspring. Maternal HF induced a transient increased body weight at weaning, and a mild glucose intolerance only in 3-month-old male mice with no change in plasma metabolic parameters in adult male and female offspring. Behavioral alterations revealed by a Barnes maze test were observed both in 6-month-old male and female mice. The multi-omics strategy unveiled sex-specific transcriptomic and proteomic modifications in the hippocampus of adult offspring. These studies that were confirmed by regulon analysis show that, although genes whose expression was modified by maternal HF were different between sexes, the main pathways affected were similar with mitochondria and synapses as main hippocampal targets of maternal HF. The effects of maternal HF reported here may help to better characterize sex-dependent molecular pathways involved in cognitive disorders and neurodegenerative diseases.

DHA Supplementation of Obese Rats throughout Pregnancy and Lactation Modifies Milk Composition and Anxiety Behavior of Offspring. Nutrients 2021; 13:nu13124243.

Abstract
We investigated if supplementing obese mothers (MO) with docosahexaenoic acid (DHA) improves milk long-chain polyunsaturated fatty acid (LCPUFA) composition and offspring anxiety behavior. From weaning throughout pregnancy and lactation, female Wistar rats ate chow (C) or a high-fat diet (MO). One month before mating and through lactation, half the mothers received 400 mg DHA kg−1 d−1 orally (C+DHA or MO+DHA). Offspring ate C after weaning. Maternal weight, total body fat, milk hormones, and milk nutrient composition were determined. Pups’ milk nutrient intake was evaluated, and behavioral anxiety tests were conducted. MO exhibited increased weight and total fat, and higher milk corticosterone, leptin, linoleic, and arachidonic acid (AA) concentrations, and less DHA content. MO male and female offspring had higher ω-6/ ω-3 milk consumption ratios. In the elevated plus maze, female but not male MO offspring exhibited more anxiety. MO+DHA mothers exhibited lower weight, total fat, milk leptin, and AA concentrations, and enhanced milk DHA. MO+DHA offspring had a lower ω-6/ω-3 milk intake ratio and reduced anxiety vs. MO. DHA content was greater in C+DHA milk vs. C. Supplementing MO mothers with DHA improves milk composition, especially LCPUFA content and ω-6/ω-3 ratio reducing offspring anxiety in a sex-dependent manner.

Abstract
Brain development is a life-long process that encompasses several critical periods of transition, during which significant cognitive changes occur. Embryonic development, puberty, and reproductive senescence are all periods of transition that are hypersensitive to environmental factors. Rather than isolated episodes, each transition builds upon the last and is influenced by consequential changes that occur in the transition before it. Epigenetic marks, such as DNA methylation and histone modifications, provide mechanisms by which early events can influence development, cognition, and health outcomes. For example, parental environment influences imprinting patterns in gamete cells, which ultimately impacts gene expression in the embryo which may result in hypersensitivity to poor maternal nutrition during pregnancy, raising the risks for cognitive impairment later in life. This review explores how epigenetics induce and regulate critical periods, and also discusses how early environmental interactions prime a system towards a particular health outcome and influence susceptibility to disease or cognitive impairment throughout life.

Abstract
We previously reported that following long-term hypoxia (LTH), the ovine foetus exhibits enhanced expression of brown/beige adipose genes. This study was designed to determine if these changes are preserved after birth. Pregnant ewes were divided among three groups, 1) Control, sea level, 2) LTH, high altitude (3,820 m, LTH-HA) from ~ day 40 of gestation through ~14 days post-delivery and 3) LTH from ⁓ day 40 through day 137 of gestation then returned to the laboratory where atory reduced maternal PO2 was maintained by nitrogen infusion. Following delivery, lambs remained at sea level (LTH-SL). Perirenal adipose tissue was collected at ~day 14, and qRT-PCR was used to quantify mRNA. Uncoupling protein 1 (UCP-1), PPAR gamma coactivator 1 (PGC1α), and deiodinase-2 (DIO2) mRNA levels were significantly lower in both LTH groups while PR domain containing 16 (PRDM16) levels did not differ. Peroxisome proliferator-activated receptor (PPARγ) was maintained in the LTH-HA group and significantly increased in the LTH-SL group, compared to control. Unlike our previous LTH foetal studies, the brown/beige fat phenotype was rapidly lost by day 14 postpartum compared to control, while PPARγ was maintained. This loss of the brown fat phenotype may promote obesity due to decreased energy expenditure, favouring fat deposition.

Abstract
BACKGROUND/OBJECTIVES Nutritional status and food intake during pregnancy and lactation can affect fetal programming. In the current metabolic syndrome epidemic, high-fructose diets have been strongly implicated. This study investigated the effect of maternal high-fructose intake during pregnancy and lactation on the development of metabolic syndrome in adult offspring. SUBJECTS/METHODS Drinking water with or without 20% fructose was administered to female C57BL/6J mice over the course of their pregnancy and lactation periods. After weaning, pups ate regular chow. Accu-Chek Performa was used to measure glucose levels, and a tail-cuff method was used to examine systolic blood pressure. Animals were sacrificed at 7 months, their livers were excised, and sections were stained with Oil Red O and hematoxylin and eosin (H&E) staining. Kidneys were collected for gene expression analysis using quantitative real-time Polymerase chain reaction. RESULTS Adult offspring exposed to maternal high-fructose intake during pregnancy and lactation presented with heavier body weights, fattier livers, and broader areas under the curve in glucose tolerance test values than control offspring. Serum levels of alanine aminotransferase, aspartate aminotransferase, glucose, triglycerides, and total cholesterol and systolic blood pressure in the maternal high-fructose group were higher than that in controls. However, there were no significant differences in mRNA expressions of renin-angiotensin-aldosterone system genes and sodium transporter genes. CONCLUSIONS These results suggest that maternal high-fructose intake during pregnancy and lactation induces metabolic syndrome with hyperglycemia, hypertension, and dyslipidemia in adult offspring.

Abstract
Abstract
Lactation is a critical period during which maternal nutritional and environmental challenges affect milk composition and, therefore, organ differentiation, structure, and function in offspring during the early postnatal period. Evidence to date shows that lactation is a vulnerable time during which transient insults can have lasting effects, resulting in altered health outcomes in offspring in adult life. Despite the importance of the developmental programming that occurs during this plastic period of neonatal life, there are few comprehensive reviews of the multiple challenges—especially to the dam—during lactation. This review presents milk data from rodent studies involving maternal nutritional challenges and offspring outcome data from studies involving maternal manipulations during lactation. Among the topics addressed are maternal nutritional challenges and the effects of litter size and artificial rearing on offspring metabolism and neural and endocrine outcomes. The lactation period is an opportunity to correct certain functional deficits resulting from prenatal challenges to the fetus, but, if not personalized, can also lead to undesirable outcomes related to catch up-growth and overnutrition.

Abstract
Before weaning, breast milk is the physiological form of neonatal nutrition, providing pups with all nutrient requirements. Maternal low-protein diet (LPD) during pregnancy and lactation induces adverse changes in key maternal organs, which have negative effects on pup development. We studied the effects of maternal LPD on liver weight, mammary gland (MG) cell differentiation, milk composition and production and pup development throughout lactation. We fed rats with control (C) or LPD (R) during pregnancy and lactation. At 7 d early, 14 d mid and 21 d late lactation stages, maternal biochemical parameters, body, liver and MG weights were analysed. MG cell differentiation was analysed by haematoxylin and eosin staining; milk nutrient composition and production were studied; pup body, liver and brain weights, hippocampal arachidonic acid (AA) and DHA were quantified. Results showed lower body and liver weights, minor MG cell differentiation and lower serum insulin and TAG in R compared with C. R milk contained less protein and higher AA at early and mid stages compared with C. R pup milk and fat intake were lower at all stages. R protein intake at early and mid stages and DHA intake at mid and late stages were lower compared with C. In R pups, lower body, liver and brain weights were associated with decreased hippocampal AA and DHA. We conclude that maternal LPD impairs liver and MG function and induces significant changes in maternal milk composition, pup milk intake and organ development.

Abstract
Background Nutrition and healthy eating behaviors during pregnancy are vitally important for the health of a mother and her developing baby. However, some midwives have reported a lack of evidence-based nutrition knowledge for providing information about healthy eating to women during pregnancy. Objective In this study, the aim is to design and evaluate a healthy eating education program to enhance midwives’ knowledge, understanding, and confidence to support pregnant women in South Australia to make healthy eating choices. Methods This mixed-methods study consists of two phases. The first phase, Phase 1, consists of an education program for midwives, “Healthy Eating in Pregnancy,” to be delivered through a workshop or webinar. Each midwife will attend one workshop or webinar, which will be approximately two hours in length. This program will be evaluated through pre-, immediate-, and post-educational questionnaires utilizing a website specifically designed for this study. The participants will be midwives who are members of the Australian College of Midwives and the Australian Nursing and Midwives Federation, and users of social media (eg, Facebook and Twitter) residing and employed in South Australia. Phase 2 will consist of semistructured interviews with a purposive sample of midwives. These interviews will be undertaken to gain an in-depth understanding of midwives’ views and how confident they feel educating pregnant women after receiving the healthy eating education. Interviews will be face-to-face or conducted by telephone with midwives who have participated in the healthy eating educational program. Results A systematic review has previously been undertaken to inform this study protocol. This paper describes and discusses the protocol for this mixed-methods study, which will be completed in April 2019. Conclusions The results from the systematic review suggest that there is clear justification to undertake this mixed-methods study to investigate and explore midwives’ knowledge, understanding and confidence to support healthy eating in pregnant women. The results and conclusions from the systematic review provided some guidance for the design and development of this study protocol. This mixed-methods study will address a gap in the literature. The results from quantitative and qualitative data sources in this proposed study will help to draw conclusions to address the research topic. Registered Report Identifier RR1-10.2196/9861

Midwifery 2017; 46:37-44. [PMID: 28161688 DOI: 10.1016/j.midw.2017.01.012] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2016] [Revised: 12/30/2016] [Accepted: 01/19/2017] [Indexed: 01/08/2023]
Abstract
OBJECTIVE to explore the experiences, wishes and needs of pregnant women with respect to health education in primary care with midwives. DESIGN qualitative semi-structured interview study, using thematic analysis and constant comparison. SETTING AND PARTICIPANTS twenty-two pregnant women in midwife-led primary care, varying in socio-demographic characteristics, weeks of pregnancy and region of residence in the Netherlands, were interviewed between April and December 2013. FINDINGS women considered midwives to be the designated health caregivers for providing antenatal health education, and generally appreciated the information they had received from their midwives. Some women, however, believed the amount of verbal health information was insufficient; others that there was too much written information. Many women still had questions and expressed uncertainties regarding various health issues, such as weight gain, alcohol, and physical activity. They perceived their health education to be individualised according to their midwives' assessments of the extent of their knowledge, as well as by the questions they asked themselves. A few were concerned that midwives may make incorrect assumptions about the extent of their knowledge. Women also varied in how comfortable they felt about contacting their midwives for questions between antenatal visits. Women felt that important qualities for midwives underlying health education, were making them feel at ease and building a relationship of trust with them. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE health education was highly appreciated by women in general, suggesting that midwives should err on the side of providing too much verbal information, as opposed to too little. A more pro-active approach with information provision may be of value not only to those with a clear desire for more information, but also to those who are unsure of what information they may be missing. As midwives are the principal health care providers throughout pregnancy,they should ideally emphasise their availability for questions between antenatal visits.

Associations between noncommunicable disease risk factors, race, education, and health insurance status among women of reproductive age in Brazil - 2011. Prev Med Rep 2016; 3:333-7. [PMID: 27419033 PMCID: PMC4929178 DOI: 10.1016/j.pmedr.2016.03.015] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2015] [Revised: 03/25/2016] [Accepted: 03/28/2016] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Noncommunicable disease (NCD) risk factors increase the risk of adverse reproductive health outcomes and are becoming increasingly common in Brazil. METHODS We analyzed VIGITEL 2011 telephone survey data for 13,745 Brazilian women aged 18-44 years in a probabilistic sample from 26 Brazilian state capitals and the Federal District. We examined associations between NCD risk factors (fruit and vegetable intake, leisure time physical activity, alcohol consumption, smoking status, BMI and hypertension status) and race, education, and insurance using chi-square tests and multivariable logistic regression models, estimating the average marginal effects to produce adjusted relative risk ratios (aRRs). Analyses were conducted using SAS 9.3 survey procedures and weighted to reflect population estimates. RESULTS Women with less than a college education were more likely to report physical inactivity (adjusted relative risk (aRR) and 95% confidence interval = 1.1 (1.1-1.2)), smoking (aRR = 1.7 (1.3-2.2)), and self-reported diagnoses of hypertension (aRR = 2.0 (1.6-2.5)) compared to women with a college education or greater. Similarly, women without health insurance were more likely to report physical inactivity (aRR = 1.1 (1.1-1.2)), smoking (aRR = 1.4 (1.1-1.8)), and self-reported diagnoses of hypertension aRR = 1.4 (1.1-1.7)) compared to women with health insurance. Less variation was found by race and NCD risk factors. CONCLUSION Targeted public health strategies and policies are needed to increase healthcare access and decrease educational and racial disparities in NCD risk factors among women of reproductive age in Brazil.

Abstract
Noncommunicable diseases (NCDs) are responsible for 36 million deaths every year. Of this death toll, nearly 80% (29 million) occur in low- and median-income countries. More than 9 million deaths attributed to NCDs occur in people under 60 years of age. National economies are suffering considerable losses due to premature death or disability to work resulting from heart disease, stroke, and diabetes. The knowledge that in utero and in early childhood certain processes can affect the risk of developing NCDs provides an opportunity to enforce interventions during this critical time, when they may have the greatest effect. Using appropriate protocols, the health-care provider can educate mothers about the risks of certain nutritional and environmental exposures and integrate health promotion on the agenda, as part of the social and economic development. All this could motivate a substantial reduction in the risk of NCDs. Current and future health challenges demand new and changing competencies that should form the basis for education, training, and workforce planning. The International Federation of Gynaecology and Obstetrics (FIGO) is aware of that responsibility and has joined hands with other agencies and organizations that make a considerable effort in providing appropriate prenatal care programs to prevent and treat most of the common preconditioning factors, especially in low-income countries.

Abstract
Increasing evidence suggests that alterations in early nutrition programme physiological changes in adulthood. In the present study, we determined the effects of undernutrition during gestation and lactation on the programming of thyroid function in adult rat offspring. Perinatal undernutrition was achieved by a 40 % food restriction in female Wistar rats from the mating day to weaning. On postpartum day 21, the offspring of the control and food-restricted dams were weaned and given free access to a commercial diet until adulthood. The results showed that undernourished rats exhibited decreased 3,5,3′-triiodothyronine (T3) levels but had normal thyroxine (T4) and thyrotropin (TSH) levels at weaning; on day 90, these rats displayed a significant flip, exhibiting normalised T3(total and free) and total T4levels, but low free T4and persistently higher TSH levels, which were maintained even on postnatal day 140. This profile was accompanied by a scarce fat depot, a lower RMR and an exacerbated sympathetic brown adipose tissue (BAT) tone (deiodinase type 2 expression) in basal conditions. Moreover, when a functional challenge (cold exposure) was applied, the restricted group exhibited partial changes in TSH (29v.100 %) and T4(non-responsev.17 %) levels, a significant decrease in leptin levels (75v. 32 %) and the maintenance of a sympathetic BAT over-response (higher noradrenaline levels) in comparison with the control group. The findings of the present study suggest that undernutrition during the perinatal period produces permanent changes in the hypothalamus–pituitary–thyroid axis with consequent low body weight and decreased RMR and facultative thermogenesis. We hypothesise that these changes predispose individuals to exhibiting adult subclinical hypothyroidism.

Abstract
Metabolic syndrome (MS) has reached epidemic proportions worldwide among children. Early life "programming" is now thought to be important in the etiology of obesity, type 2 diabetes, cardiovascular disease and MS. Nutritional imbalance and exposures to endocrine disruptor chemicals during development can increase risk for MS later in life. Epigenetic marks may be reprogrammed in response to both stochastic and environmental stimuli, such as changes in diet and the in utero environment, therefore, determination of targets for early life effects on epigenetic gene regulation provides insight into the molecular mechanisms involved in the epigenetic transgenerational inheritance of a variety of adult onset disease phenotypes. The perinatal period is a crucial time of growth, development and physiological changes in mother and child, which provides a window of opportunity for early intervention that may induce beneficial physiological alternations.

Abstract
Adverse environments during the fetal and neonatal development period may permanently program physiology and metabolism, and lead to increased risk of diseases in later life. Programming of the hypothalamic-pituitary-adrenal (HPA) axis is one of the key mechanisms that contribute to altered metabolism and response to stress. Programming of the HPA axis often involves epigenetic modification of the glucocorticoid receptor (GR) gene promoter, which influences tissue-specific GR expression patterns and response to stimuli. This review summarizes the current state of research on the HPA axis and programming of health and disease in the adult, focusing on the epigenetic regulation of GR gene expression patterns in response to fetal and neonatal stress. Aberrant GR gene expression patterns in the developing brain may have a significant negative impact on protection of the immature brain against hypoxic-ischemic encephalopathy in the critical period of development during and immediately after birth.

Abstract
Adverse events during intrauterine life may program organ growth and favor disease later in life. This is the usually called 'Barker's hypothesis'. Increasing evidence suggests that conditions like vascular disease, hypertension, metabolic syndrome, and type 2 diabetes mellitus are programmed during the early stages of fetal development and become manifest in late stages of life, when there is an added impact of lifestyle and other conventional acquired environmental risk factors that interact with genetic factors. The aim of this review was to provide additional, updated evidence to support the association between intrauterine fetal health and increased prevalence of chronic non-communicable diseases in adulthood. Various potential cellular and molecular mechanisms proposed to be related to the above hypothesis are discussed, including endothelial function, oxidative stress, insulin resistance, and mitochondrial function.

Abstract
In mice, exposure to isoflavones (ISO), abundant in soy infant formula, during the first 5 d of life alters structural and functional development of reproductive organs. Effects of longer exposures are unknown. The study objective was to evaluate whether exposure to a combination of daidzein and genistein in the first 10 compared to 5 d of life results in greater adverse effects on ovarian and uterine structure in adult mice. Thirteen litters of 8-12 pups were cross-fostered and randomized to corn oil or ISO (2 mg daidzein + 5 mg genistein/kg body weight/d) for the first 5 or 10 d of life. The 10-d protocol mimicked the period when infants are fed soy protein formula (SPF) but avoids the time when suckling pups can consume mother's diet. Body and organ weights, and histology of ovaries and uteri were analyzed. There were no differences in the ovary or uterus weight, number of ovarian follicles, number of multiple oocyte follicles, or percent of ovarian cysts with 5 or 10 d ISO intervention compared to respective controls. The 10-d ISO group had higher body weights from 6 d to 4 mo of age and a higher percent of hyperplasia in the oviduct than the respective control. Lower number of ovarian corpus lutea and a higher incidence of abnormal changes were reported in the uteri of both ISO groups compared to their respective controls. Five and 10-d exposure to ISO had similar long-lasting adverse effects on the structure of ovaries and uterus in adult mice. Only the 10-d ISO exposure resulted in greater body weight gain at adulthood.
