Abstract
Background: Human milk diet, preferably mother's own milk (MOM) over donor milk (DM), is recommended for preterm infants. Expression of MOM in proximity to preterm infants, especially during or immediately after skin-to-skin contact (SSC), is associated with greater milk production. However, the correlation between SSC and MOM production during hospital admission in preterm infants has not yet been studied. Our study investigated the relationship between SSC and MOM production and consumption in preterm infants during the first postnatal month of life. Materials and Methods: This was a prospective cohort study. Mothers and their preterm infants born at <35 weeks by gestational age (GA) and eligible for SSC within the first 5 postnatal days were eligible for the study. Mothers were given a binder to document pumped breast milk volumes and SSC sessions. Pumped breast milk volumes, enteral feeding type and volume, and SSC duration and frequency were collected daily over the first 28 days of life, along with demographic, perinatal, and feeding data from electronic medical records (EMR). Results: Mean birth GA and weight were 30 ± 3 weeks and 1,443 ± 576 g, respectively. SSC duration was inversely correlated with GA and weight. The SSC duration was positively correlated with ingested MOM volume after correcting for birth GA. The SSC duration was predictive of increased volumes of pumped MOM. Conclusion: Our findings suggest that SSC duration is associated with improved MOM production and consumption. SSC can be a useful tool to increase MOM exposure and improve long-term health outcomes in preterm infants.

Adverse pregnancy outcomes in Toxoplasma gondii seropositive Hispanic women. J Obstet Gynaecol Res 2023; 49:893-903. [PMID: 36495217 PMCID: PMC9991953 DOI: 10.1111/jog.15511] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 10/24/2022] [Accepted: 11/13/2022] [Indexed: 12/14/2022]
Abstract
AIMS Chronic Toxoplasma gondii infection is not thought to affect pregnancy or birth outcomes, but there are few prospective studies. The study aims were T. gondii immunoglobulin G measurement and relationship of chronic T. gondii infection with gestational age at birth and adverse pregnancy outcomes in 690 Hispanic women in Tampa, Florida. METHODS Hispanic women, born either in the United States or in Latin America or the Caribbean had a venous blood sample drawn to measure T. gondii IgG and T. gondii serotype at the first prenatal visit, along with collection of demographic and health-related measures. Seropositive and seronegative women were followed throughout their pregnancy. Gestational age, infant weights, and adverse pregnancy outcomes (miscarriages, preterm births) were compared in the two groups. RESULTS There were 740 women of self-reported Hispanic ethnicity screened and enrolled in Tampa, Florida, with 690 having birth data extracted from the electronic health record (538 T. gondii negative and 152 T. gondii seropositive). T. gondii seropositivity was 22.4% and the majority (83%) had high avidity titers, indicating chronic infection. Compared to T. gondii seronegative Hispanic women, seroseropositive women had more smaller for gestational age infants and higher prevalences of miscarriages and preterm birth. CONCLUSION This is one of the largest longitudinal cohort studies of women with chronic T. gondii infection followed through pregnancy. There was a higher percentages of adverse pregnancy outcomes in this group compared to T. gondii seronegative controls. The mechanism for this is unknown and warrants reexamination of the dogma that chronic T. gondii infection in pregnant women has no significant clinical consequences.

Perinatal Health Outcomes Across Rural and Nonrural Counties Within a Single Health System Catchment. WOMEN'S HEALTH REPORTS (NEW ROCHELLE, N.Y.) 2023; 4:169-181. [PMID: 37096122 PMCID: PMC10122232 DOI: 10.1089/whr.2022.0061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Accepted: 12/13/2022] [Indexed: 04/26/2023]
Abstract
Background Perinatal health outcomes are influenced by a variety of socioeconomic, behavioral, and economic factors that reduce access to health services. Despite these observations, rural communities continue to face barriers, including a lack of resources and the fragmentation of health services. Objective To evaluate patterns in health outcomes, health behaviors, socioeconomic vulnerability, and sociodemographic characteristics across rural and nonrural counties within a single health system catchment area. Methods Socioeconomic vulnerability metrics, health care access as determined by licensed provider metrics, and behavioral data were obtained from FlHealthCHARTS.gov and the County Health Rankings. County-level birth and health data were obtained from the Florida Department of Health. The University of Florida Health Perinatal Catchment Area (UFHPCA) was defined as all Florida counties where ≥5% of all infants were delivered at Shands Hospital between June 2011 and April 2017. Results The UFHPCA included 3 nonrural and 10 rural counties that represented more than 64,000 deliveries. Nearly 1 in 3 infants resided in a rural county, and 7 out of 13 counties did not have a licensed obstetrician gynecologist. Maternal smoking rates (range 6.8%-24.8%) were above the statewide rate (6.2%). Except for Alachua County, breastfeeding initiation rates (range 54.9%-81.4%) and access to household computing devices (range 72.8%-86.4%) were below the statewide rate (82.9% and 87.9%, respectively). Finally, we found that childhood poverty rates (range 16.3%-36.9%) were above the statewide rate (18.5%). Furthermore, risk ratios suggested negative health outcomes for residents of counties within the UFHPCA for each measure, except for infant mortality and maternal deaths, which lacked sample sizes to adequately test. Conclusions The health burden of the UFHPCA is characterized by rural counties with increased maternal death, neonatal death, and preterm birth, as well as adverse health behaviors that included increased smoking during pregnancy and lower levels of breastfeeding relative to nonrural counties. Understanding perinatal health outcomes across a single health system has potential to not only estimate community needs but also facilitate planning of health care initiatives and interventions in rural and low-resource communities.

Abstract
Although sexual and reproductive health inequities acutely and disproportionately affect Black women in the USA, there are few studies that consider the sociocultural context in which Black women transition to adulthood and develop their sexuality. The objective of this study was to describe the lived realities of young Black women to elucidate how the sociocultural context informs their current perceptions of sexual and reproductive health. We conducted phenomenological interviews with 22 Black women aged 18-29 years to elicit their life stories. The main categories identified in the findings include how the sociocultural environment informs the self-concept; how the sociocultural environment informs early learning about sexual health; and how together these experiences inform women's development of a sexual self-concept. Three main groupings of experiences were identified relative to women's sexual self-concept: fear-based disease and pregnancy prevention; a deeper understanding of bodies and sexuality beyond disease and pregnancy prevention; and sexual pleasure and fulfilment as a priority. To address ongoing sexual and reproductive health inequities that particularly disadvantage young Black women, health systems and interventions should address the sociocultural contexts in which young Black women develop and manage their sexual health.

Abstract
A central goal of the Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient. The Academy of Breastfeeding Medicine recognizes that not all lactating individuals identify as women. Using genderinclusive language, however, is not possible in all languages and all countries and for all readers. The position of the Academy of Breastfeeding Medicine (https://doi.org/10.1089/bfm.2021.29188.abm) is to interpret clinical protocols within the framework of inclusivity of all breastfeeding, chestfeeding, and human milk-feeding individuals.

Detection of SARS-CoV-2 specific antibodies in breastfeeding infant stool following mother’s COVID-19 vaccination. THE JOURNAL OF IMMUNOLOGY 2022.

Abstract
Abstract
In December 2020, efficacious COVID-19 vaccines were approved for use and since, millions have been immunized against SARS-CoV-2, the virus responsible for COVID-19. It is known that administration of the COVID-19 vaccine leads to increased SARS-CoV-2 specific antibodies in plasma and human milk. While this increase has been studied, the durability, longevity, and efficacy of these antibodies remains unknown. Historically, human milk serves a vital role in providing protection and nutrients to infants, and with COVID-19 vaccines not approved for children under five, immunity and protection from vaccinated mothers is likely a crucial barrier for infant safety. This study aimed at determining how long these antibodies remain in plasma and milk after COVID-19 vaccination, how effective these antibodies are at neutralizing SARS-CoV-2, and if antibodies are detectable in breastfeeding infant stool after mother has been vaccinated. This study found that concentrations of SARS-CoV-2 specific IgA and IgG decrease over 6 months post vaccine, but remain higher than pre-vaccination levels in plasma and milk. Although post-neutralization efficacy decreased over a 6-month period in plasma, using a pseudo-type vaccine neutralization assay, neutralization efficacy in human milk became more robust over the same period. Notably, we found elevated levels of SARS-CoV-2 specific IgA and IgG and neutralization within the stool of breastfeeding infants, post COVID vaccination compared to pre-COVID stool. Although further studies will be needed to determine the full extent of this passive immunity, these studies implicate the maternal/infant transfer of neutralizing SARS-CoV-2 specific antibodies through human milk subsequent to vaccination.

Abstract
Cauda equina syndrome (CES) is a rare condition that occurs from multiple nerve root compression. It is considered a surgical emergency because it can lead to permanent neurological damage. There is limited literature regarding management and prognosis of CES for pregnant patients, leaving providers with many questions when encountering patients with this condition. We describe the case of a patient who developed CES during pregnancy. She presented at 30 weeks gestation and successfully underwent surgical decompression in prone position. She later delivered via elective caesarean at term. This case highlights management considerations for pregnant patients with CES, including positioning during surgery and use of regional anaesthesia.

Abstract
Idiopathic granulomatous mastitis (IGM) is a rare benign breast condition with a course that is often rapidly progressive and slow to resolve. There is no consensus on management, especially during pregnancy and lactation. A 30-year-old at 33 weeks presented with mastalgia, induration and galactorrhoea in the left breast. There was no improvement with antibiotics. Initial workup was negative, and a core needle biopsy showed findings consistent with the diagnosis of IGM. She was treated with steroids antepartum. She was co-managed by rheumatology and her obstetrician/breastfeeding medicine specialist postpartum. She was treated with azathioprine, breastfed exclusively for 6 months and continued breastfeeding through the first year. A multidisciplinary team approach is crucial in diagnosing, treating, and facilitating successful breastfeeding in patients with IGM.

Abstract
Rectal laceration in the absence of concurrent anal sphincter injury at the time of parturition is not a frequently reported finding. This rarely encountered injury is also referred to as a buttonhole injury. It is a disruption of the vaginal and rectal tissue with resultant disruption of the anal epithelium in the setting of an intact external anal sphincter. A 30-year-old gravida 1 para 0 at 39 weeks presented for induction of labour due to chronic hypertension. During her labour course, she developed with superimposed preeclampsia with severe features and magnesium sulfate was initiated. She underwent a spontaneous vaginal delivery of an infant weighing 3840 g. Following delivery, stool was visualised in the vagina. A rectal examination revealed a rectovaginal defect separate from the second-degree perineal laceration, which extended proximally to the cervix. The anal sphincter was noted to be intact with good tone. Both defects were repaired, and she had an uncomplicated recovery.

Abstract
While family planning care (FPC) visits may serve as opportunities to address gaps in knowledge and access to limited resources, young Black women may also face structural barriers (i.e., racism, discrimination, bias) to engaging in care due to the intersections of racial identity, age, and socioeconomic status. Findings from interviews with 22 Black women, ages 18 to 29 years, about the lived experience of FPC highlighted dynamic patient-provider encounters. Women's narratives uncovered the following essences: silence around sex impedes engagement in care, patient-provider racial concordance as protection from harm, providers as a source of discouragement and misinformation, frustration as a normative experience, decision making excludes discussion and deliberation, medical mistrust is pervasive and a part of Black consciousness, and meaningful and empathic patient-provider encounters are elusive. Health systems should prioritize developing and enhancing young Black women's relationship with FPC providers to help mitigate persistent inequities that perpetuate disadvantage among this population.

Abstract
BACKGROUND Electronic health records (EHRs) hold great potential for longitudinal mother-baby studies, ranging from assessing study feasibility to facilitating patient recruitment to streamlining study visits and data collection. Existing studies on the perspectives of pregnant and breastfeeding women on EHR use have been limited to the use of EHRs to engage in health care rather than to participate in research. OBJECTIVE The aim of this study is to explore the perspectives of pregnant and breastfeeding women on releasing their own and their infants' EHR data for longitudinal research to identify factors affecting their willingness to participate in research. METHODS We conducted semistructured interviews with pregnant or breastfeeding women from Alachua County, Florida. Participants were asked about their familiarity with EHRs and EHR patient portals, their comfort with releasing maternal and infant EHR data to researchers, the length of time of the data release, and whether individual research test results should be included in the EHR. The interviews were transcribed verbatim. Transcripts were organized and coded using the NVivo 12 software (QSR International), and coded data were thematically analyzed using constant comparison. RESULTS Participants included 29 pregnant or breastfeeding women aged between 22 and 39 years. More than half of the sample had at least an associate degree or higher. Nearly all participants (27/29, 93%) were familiar with EHRs and had experience accessing an EHR patient portal. Less than half of the participants (12/29, 41%) were willing to make EHR data available to researchers for the duration of a study or longer. Participants' concerns about sharing EHRs for research purposes emerged in 3 thematic domains: privacy and confidentiality, transparency by the research team, and surrogate decision-making on behalf of infants. The potential release of sensitive or stigmatizing information, such as mental or sexual health history, was considered in the decisions to release EHRs. Some participants viewed the simultaneous use of their EHRs for both health care and research as potentially beneficial, whereas others expressed concerns about mixing their health care with research. CONCLUSIONS This exploratory study indicates that pregnant and breastfeeding women may be willing to release EHR data to researchers if researchers adequately address their concerns regarding the study design, communication, and data management. Pregnant and breastfeeding women should be included in EHR-based research as long as researchers are prepared to address their concerns.

Abstract
BACKGROUND The human milk microbiome is an emerging scientific area. Careful, accurate collection and measurement for microbial sequencing is imperative. There is controversy about a core microbiome, and little is known about factors that influence composition. Even less known are ways that the milk microbiome might seed the infant gut and affect health. RESEARCH AIM The aim of this paper is to provide a critical appraisal of milk microbiome research. The four areas of critical appraisal were collection and measurement, composition, effects on composition, and potential health effects for infants related to the milk microbiome. METHODS Using a PRISMA-ScR scoping review, we reviewed sources of evidence extracted from PubMed, Web of Science, CINAHL, Academic Search Complete, and PSYCHINFO data sets using the following criteria: English language, published in past 6 years, primary data, and sequencing using Next Generation Sequencing. Charting of sources of evidence included authors, title, journal year, sample, design, and results. The research questions posed were: How is human milk collected and how are the microbes identified? What is the composition and what factors affect the human milk microbiome? What is the relationship of the human milk microbiome to infant biology and health? RESULTS The reviewed studies were quantitative, cross sectional, or longitudinal. A core microbiome may be present. The microbiome may seed the early infant gut and promote physiological functions and thus influence human health. CONCLUSIONS We have suggested concerns about collection and measurement that lead to gaps in knowledge generation, and mechanistic studies are lacking.

Abstract
OBJECTIVES We sought to investigate the feasibility of a behavioral sleep intervention for insomnia, delivered through group prenatal care and the relationship of this intervention to improvements in insomnia symptoms and sleep quality. PARTICIPANTS Women receiving prenatal care and reporting a pre-pregnancy BMI of ≥25 kg/m2 and sleep duration of <6.5 h per night. METHODS Participants were randomized to group prenatal care or group prenatal care with a behavioral sleep intervention, adapted from cognitive behavioral therapy for insomnia (CBT-I) online program Go! to Sleep®. In the second trimester (T1), late third trimester (T2) and 6-8 weeks postpartum (T3) study assessments were completed including the Insomnia Severity Index, Pittsburgh Sleep Quality Index, fasting glucose and insulin and weight and height. Data were analyzed using independent samples t-tests, chi-square tests, correlations, and two-way repeated measures ANOVA where appropriate. P < .05 was set as the level of significance. RESULTS From May 2014 to April 2015, 311 women were evaluated for inclusion and 53 women were randomized to participate (27 intervention; 26 control), 15% were lost to follow up. The intervention group had lower third trimester and postpartum levels of moderate to severe insomnia (T2 50.0% vs 85.0% (p = .018) and T3 13.6% vs 52.4% (p-.008)) and mean insomnia severity scores (T2 (14.7 (±6.6) vs 19.3 (± 6.0) p = .02) and T3 (9.7 (±5.4) vs 15.1(±7.2) p = .01)) when compared to the control group. CONCLUSION A randomized controlled trial of a behavioral sleep intervention for insomnia delivered through group prenatal care led to improvements in insomnia symptoms.

Abstract
BACKGROUND The postpartum period can be a vulnerable time during which many women are prone to mood disturbances. Since telomere length (TL) is known to be associated with dysphoric moods, inflammation, and stress in many populations, this study's objective was to assess the relationships among TL, dysphoric moods, stress, and inflammation during the postpartum period. METHOD This cross-sectional pilot study is a secondary analysis of data collected in a larger parent study of anti-thyroid peroxidase (TPO) enzyme antibody positive versus negative women. The parent study followed selected mothers every month for 6 postpartum months. From this parent study, a random sample of preserved peripheral blood mononuclear cells from 97 participants collected at 2-4 months postpartum were measured for TL. Data were available on the production of interleukin-6 (IL-6), an inflammatory cytokine, in stimulated ex vivo cultures for 59 of these women. Dysphoric moods and stress were measured. Pearson correlations and linear regressions were performed, controlling for postpartum thyroiditis status and age. RESULTS There were no statistically significant relationships between TL and demographic factors, stress, depression, or TPO status. There were significant negative correlations between TL and anxiety and a trend for a relationship between TL and IL-6 levels. IL-6 levels were significantly, positively associated with negative moods. CONCLUSIONS Higher anxiety scores and inflammation were associated with shorter TL. Inflammation was related to anxiety and other dysphoric moods and was marginally associated with shorter TLs.

Abstract
PURPOSE The Heart and Pregnancy Program (HPP) was created to evaluate and manage pregnant women with cardiac conditions simultaneously by cardiology and maternal-fetal medicine (MFM). The objective of our study was to describe the experience at this multidisciplinary program. METHODS This is a retrospective review of women managed at HPP for over 4.5 years. Subjects were compared based on indication for referral. RESULTS One hundred and seventy-three women were seen during the time period. Referral indications included cardiac complaints without history of cardiac disease (n = 49, 28.3%), known cardiac disease (n = 96, 55.5%), and other high-risk conditions (n = 28, 16.2%). Those with a known history of cardiac disease were significantly more likely to be nulliparous, and those referred for other high-risk conditions were significantly more likely to be obese. Most women underwent echocardiography (n = 137, 79.2%). For the 140 women who delivered at our hospital, the average gestational age at delivery was 38.8 weeks and the Cesarean rate was 41.4% (n = 58). No significant adverse perinatal outcomes were noted. CONCLUSIONS In our collaborative cardiology/MFM practice, most pregnant women had known cardiac disease. No significant adverse outcomes were noted. Our experience provides support for creating a joint model of care for pregnant women with cardiac disease.

Abstract
A large urban hospital in Florida implemented changes to achieve the Baby-Friendly Hospital Initiative (BFHI) designation in 2015 resulting in an increase of exclusive breastfeeding rates at hospital discharge; however, African American women continue to have the lowest rates overall. Qualitative interviews were conducted with 20 African American women who received prenatal care at a low-income women's clinic and gave birth at an affiliated BFHI hospital. Using a medical anthropology analytical framework to examine predisposing, enabling, and service-related factors that affect breastfeeding, this study investigated interpersonal, sociocultural, and institutional barriers to breastfeeding. Common challenges experienced by participants included lack of maternity leave from work, lack of access to electric pumps, social pressures to initiate formula supplementation, fears that breastfeeding renders infants overly dependent on their mother's care, and a lack of breastfeeding role models and/or support networks to normalize longer-term breastfeeding. We conclude that efforts to increase breastfeeding rates for African American women and promote culturally sensitive interventions must address underlying socioeconomic and structural barriers, women's perceptions of breastfeeding benefits and difficulties, and the need for improvements in postnatal lactation and doula support to foster a more inclusive culture of breastfeeding.

Abstract
Purpose: To assess the role of cardiac magnetic resonance imaging (CMR) for the evaluation and management of women with cardiac disorders in pregnancy and postpartum.Methods: Retrospective record review of women at a university-affiliated, single institution referred for CMR without contrast due to known or suspected cardiac disorders between January 2010 and December 2015. Medical records, echocardiogram and CMR reports were reviewed. Instances where clinical management was changed based on CMR findings were identified.Results: There were 17 peripartum CMR studies performed without contrast in 17 pregnancies from 16 women. Indications for CMR included congenital heart disease (N = 8, 47.1%), Marfan syndrome or strong family history of Marfan syndrome (N = 5, 29.4%), cardiomyopathy (N = 1, 5.9%), cardiac mass (N = 1, 5.9%), persistent dyspnea with a normal echocardiogram (N = 1, 5.9%), and hypertension with suspected aortic root dilation (N = 1, 5.9%). CMR confirmed the echocardiogram diagnosis in eight (47.1%) and improved the diagnosis in five (29.4%). Availability of CMR findings changed the delivery management in 2/17 (11.8%) women. CMR was especially helpful in assessing the size of the aortic root in women at risk for dilation.Conclusions: Although echocardiogram imaging of the heart is considered the first-line method for assessing the maternal cardiac status, CMR can provide information about cardiac anatomy and function in pregnant women with complex cardiac disease or suspected aortic pathology. Management may be changed based on results.

Abstract
OBJECTIVE To evaluate relationships among obesity in pregnancy and plasma levels of tryptophan (TRP) and kynurenine (KYN), inflammatory markers, and depressed mood. METHODS Pregnant women ( N = 374) were enrolled, and data were collected at a mean gestation of 20 weeks in this cross-sectional study. Plasma was analyzed for TRP, KYN, neopterin, and nitrite levels. Women completed demographic and mood scales. RESULTS There was a statistically significant inverse correlation between body mass index (BMI) and TRP and positive correlations between BMI and KYN and the kynurenine/tryptophan (KYN/TRP) ratio. Neopterin was correlated with KYN/TRP, suggesting that the indoleamine 2,3-dioxygenase-1 (IDO-1) enzyme was activated. The correlations of neopterin and nitrite with BMI were too small to be clinically meaningful but may provide mechanistic insight. There was a correlation between depressed mood and nitrite levels. Depressed mood was also associated with lower TRP levels. When the sample was divided into pregnant women with or without obesity, TRP was significantly lower and the KYN/TRP ratio was significantly higher in the women with obesity. CONCLUSION The pro-inflammatory state of obesity in pregnancy may drive activation of IDO-1, resulting in diversion of TRP away from serotonin and melatonin production and toward KYN metabolites. This alteration could contribute to depression, impaired sleep, increased production of excitotoxic neurotransmitters, and reinforcement of a pro-inflammatory state in pregnancy.

Abstract
Marked racial and ethnic disparities exist in infant feeding in the United States. Based on a review of recent literature, this article examines current discrepancies between the 2020 Healthy People breastfeeding goals and current breastfeeding rates among women from different ethnic groups in the United States. We discuss maternal and child health outcomes associated with breastfeeding, and we review potential causes of racial and ethnic disparities in breastfeeding outcomes in the United States, especially among non-Hispanic Black, American Indian/Alaska Native, and Hispanic/Latina populations. We conclude with an overview of best practices in interventions aimed to increase U.S. breastfeeding rates, such as adoption of the baby friendly hospital initiative (BHFI) and programs that utilize peer counseling strategies to increase breastfeeding promotion and support.

Abstract
Objective Elevated homocysteine (HC) levels and/or shortened telomere length (TL) are associated with adverse medical conditions. Our objective is to investigate the relationship between HC and TL in cord blood leukocytes of newborns. Study Design This is a nested study from a prospective cohort from 2011 to 2012 in pregnant women admitted for delivery at a university-affiliated hospital. Cord blood was collected at delivery and genomic DNA was analyzed using quantitative PCR. The telomere-to-single copy gene ratio method was employed to quantify TL. Newborn HC levels were measured. generalized linear regression modeling (GLM) and bootstrap statistical analyses were performed. Results Seventy-seven maternal-fetal dyads with a mean gestational age of 39 weeks were included. The distribution of the coefficient of homocysteine showed most values greater than zero demonstrating that homocysteine had a positive relationship with TL. In 915 of 10,000 (9.15%) iterations, the p-value was < 0.05 demonstrating a positive effect. Conclusion Increasing newborn concentrations of HC are not associated with decreasing TL. Larger, prospective studies are needed to confirm these findings and long-term implications.

Abstract
OBJECTIVE To describe longitudinal effects of feeding volume and type of milk on fecal calprotectin (f-CP) in very low-birth weight (VLBW) infants. STUDY DESIGN Prospective data were collected across Neonatal Intensive Care Unit (NICU) admission for 6 weeks or until discharge in 75 VLBW neonates. The mean gestational age on entry into the study was 29 weeks. RESULTS Seventy-four (99%) mothers provided expressed milk in varying amounts. Twenty-three mothers (31%) provided exclusive mother's own milk (MOM) throughout. Preterm infant formula (PIF) and pasteurized donor milk were added to feedings of remaining infants. Pooled MOM was analyzed weekly for levels of a panel of cytokines, chemokines, and growth factors, and secretory Immunoglobulin A (sIgA) so that the exact amount of exposure to the gut of these milk bioactives could be estimated. f-CP levels ranged from 160 to 350 μg/g stool. Total feeding volume was positively associated with f-CP, controlling for infant weight, and f-CP levels rose across time. Exclusive MOM feedings for the entire measurement period were associated with rising levels of f-CP, but mixed feedings (MOM with added PIF or pasteurized donor milk (PDM) did not show this increase over time. CONCLUSION The presence of f-CP may represent a response to milk volumes and MOM, which represents normal development rather than always implicating pathological inflammation in the VLBW infant.

Abstract
This review describes current understandings about the nature of the very low birth weight infant (VLBW) gut microbiome. VLBW infants often experience disruptive pregnancies and births, and prenatal factors can influence the maturity of the gut and immune system, and disturb microbial balance and succession. Many VLBWs experience rapid vaginal or Caesarean births. After birth these infants often have delays in enteral feeding, and many receive little or no mother's own milk. Furthermore the stressors of neonatal life in the hospital environment, common use of antibiotics, invasive procedures and maternal separation can contribute to dysbiosis. These infants experience gastrointestinal dysfunction, sepsis, transfusions, necrotizing enterocolitis, oxygen toxicity, and other pathophysiological conditions that affect the normal microbiota. The skin is susceptible to dysbiosis, due to its fragility and contact with NICU organisms. Dysbiosis in early life may resolve but little is known about the timing of the development of the signature gut microbiome in VLBWs. Dysbiosis has been associated with a number of physical and behavioral problems, including autism spectrum disorders, allergy and asthma, gastrointestinal disease, obesity, depression, and anxiety. Dysbiosis may be prevented or ameliorated in part by prenatal care, breast milk feeding, skin to skin contact, use of antibiotics only when necessary, and vigilance during infancy and early childhood.
