Abstract
Establishing enteral nutrition after the birth of preterm infants presents numerous challenges, particularly for those in special situations. Various disease factors and medical interventions impede the establishment of enteral feeding, leading to conflicts and controversies regarding feeding goals, feeding methods, and the challenges and solutions faced by these infants. A critical issue for clinical physicians is how to safely and promptly establish enteral nutrition to achieve full enteral feeding as quickly as possible. The consensus formulation working group, based on both domestic and overseas research, adopted the Grading of Recommendations Assessment, Development and Evaluation, and formed an expert consensus on enteral nutrition management for preterm infants in special situations. This consensus provides 14 recommendations for 9 common special situations, aiming to offer guidance on enteral nutrition management for preterm infants to improve their short and long-term outcomes.

Handling of human milk to prevent acquired cytomegalovirus infection in Japanese neonatal intensive care units: The first nationwide survey. Pediatr Int 2024; 66:e15728. [PMID: 38563290 DOI: 10.1111/ped.15728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 11/13/2023] [Accepted: 11/21/2023] [Indexed: 04/04/2024]
Abstract
BACKGROUND Human milk (HM) has been proven to provide immunological and nutritional advantages to neonates; however, acquired cytomegalovirus (CMV) infection can be associated with raw HM. In Japan, there are no standardized guidelines concerning HM handling. This cross-sectional survey was performed to reveal specific trends in HM handling in neonatal intensive care units (NICUs) in Japan. METHODS A questionnaire was sent to 255 NICUs participating in the Japanese Neonatologist Association in May 2020. It involved HM handling practices, such as maternal screening, pasteurization, storage, and the workforce. RESULTS Of 255 NICUs, 174 (67.8%) responded to the survey. Maternal CMV screening was carried out in 37 units (22.2%), and CMV inactivation in HM was performed in 44 units (26.5%). For CMV inactivation, a freeze-thawing method was employed in about 90% of units. In 70% of units providing CMV inactivation, CMV inactivation was conducted regardless of bodyweight and corrected gestational age of infants until the infants' discharge. Acquired CMV infection in preterm neonates was observed in 43 units (25.7%) in the survey period. CONCLUSION A wide range of HM handling practices are used in Japanese NICUs. A national guideline for handling HM in NICUs should be created to promote the infection control of CMV.

Abstract
Human milk (HM) is considered the best source of nutrition for infant growth and health. This nourishment is unique and changes constantly during lactation to adapt to the physiological needs of the developing infant. It is also recognized as a potential route of transmission of some viral pathogens although the presence of a virus in HM rarely leads to a disease in an infant. This intriguing paradox can be explained by considering the intrinsic antiviral properties of HM. In this comprehensive and schematically presented review, we have described what viruses have been detected in HM so far and what their potential transmission risk through breastfeeding is. We have provided a description of all the antiviral compounds of HM, along with an analysis of their demonstrated and hypothesized mechanisms of action. Finally, we have also analyzed the impact of HM pasteurization and storage methods on the detection and transmission of viruses, and on the antiviral compounds of HM. We have highlighted that there is currently a deep knowledge on the potential transmission of viral pathogens through breastfeeding and on the antiviral properties of HM. The current evidence suggests that, in most cases, it is unnecessarily to deprive an infant of this high-quality nourishment and that the continuation of breastfeeding is in the best interest of the infant and the mother.

Abstract
Postnatal human cytomegalovirus (HCMV) infection in newborns is well characterized for preterm infants but less so for term infants. We sought to analyze the rates and routes of HCMV transmission in full-term infants during the first year of life. A cohort of 120 HCMV seropositive mothers and their 122 newborns were tested after delivery for HCMV-DNA shedding in different bodily fluids. Postnatal HCMV infection was defined as the detection of >2.5 × 102 HCMV-DNA copies/mL in infants' saliva swabs. Maternal neutralizing antibody serum titer, HCMV-specific T-cell response, and HCMV glycoprotein B immunoglobulin G on breastmilk were analyzed. HCMV shedding was detected in 67 of 120 mothers (55.8%), and 20 of 122 infants (16.4%) developed HCMV infection within the first 3 months of life. Six additional infants were infected during the first year, for a postnatal infection rate of 21.3%. Viral shedding was more frequent in breastmilk than saliva, urine, and vaginal secretions, and the mothers of infected infants showed higher levels of HCMV-DNA in milk. No association was found between the antibody levels in serum or milk and maternal viral shedding, whereas a slightly lower frequency of HCMV-specific CD4+ T-cells with long-term memory phenotype was observed in women with HCM-DNA-positive milk. About one out of five infants develop HCMV infection within the first year of life. Breastmilk appears the major route of transmission of the infection, maternal saliva has a minor role whereas the role of vaginal secretions is negligible.

Abstract
INTRODUCTION Reports on the influence of postnatal cytomegalovirus (pCMV) infection in neonatal outcomes of preterm babies vary while guidance on management including screening is lacking. We aim to determine the association between symptomatic pCMV infection and chronic lung disease (CLD) and mortality in preterm infants born less than 32 weeks gestation. METHODS We used data from the Neonatal Intensive Care Units' (NICUS) population-based prospective data registry of infants in 10 neonatal units in New South Wales and the Australian Capital Territory, Australia. De-identified perinatal and neonatal outcome data for 40,933 infants were examined. We identified 172 infants <32 weeks gestation with symptomatic pCMV infection. Each was matched with one control infant. RESULTS Infants with symptomatic pCMV infection were 2.7 times more likely to develop CLD (OR 2.7, 95% CI: 1.7-4.5) and spend 25.2 days more in hospital (95% CI: 15.2-35.2). Seventy-five percent (129/172) of infants with symptomatic pCMV were extremely preterm (<28 weeks). The mean age of symptomatic pCMV diagnosis was 62.5 ± 20.5 days or 34.7 ± 3.6 weeks-corrected gestational age. Ganciclovir treatment did not decrease CLD and death. CLD was 5.5 times predictive of death in patients with symptomatic pCMV infection. Symptomatic pCMV infection did not influence mortality nor increase neurologic impairment. CONCLUSION Symptomatic pCMV is a modifiable factor affecting extreme preterm infants with significant impact on CLD. Prospective study on screening and treatment will help unveil potential benefits in our already at-risk preterm infants.

Abstract
Background Human milk banks (HMBs) are essential facilities for the selection, collection, testing, transportation,storage, and distribution of DHM for special medical needs. The aim of this analysis was to analyze the operation status and data over the last 8 years of operation of the first human milk bank (HMB) in East China. Methods Data related to the costs, donors, donation, pasteurization, and recipients were extracted from the web-based electronic monitoring system of the HMB for the period August 1, 2013 to July 31, 2021. Results Over the 8 years of operation, 1,555 qualified donors donated 7,396.5L of qualified milk at a cost of ¥1.94 million($306,051), with the average cost per liter of donor human milk being ¥262.3($41.4). The donors were between 25 and 30 years of age, and the majority (80.1%) were primipara. All the donated milk was pasteurized and subjected to bacteriological tests before and after pasteurization: 95.4% passed the pre-pasteurization tests, and 96.3% passed the post-pasteurization tests. A total of 9,207 newborns received 5,775.2L of pasteurized donor milk. The main reason for the prescription of donor human milk was preterm birth. As a result of continuous quality improvements, January 2016 witnessed a significant increase in the volume of qualified DHM and the number of qualified donors. However, in 2020, as a result of the restrictions related to the COVID-19 pandemic, the volume of qualified DHM and the number of qualified donors decreased. Conclusions Over its 8 years of operation, our HMB has made steady quality improvements in its screening and information processes. Continuous quality improvement is on ongoing need, along with recruiting more qualified donors and collecting donor human milk for vulnerable newborns.

Abstract
BACKGROUND To determine the characteristics and outcomes of postnatal cytomegalovirus (pCMV) infection in preterm infants in a neonatal intensive care unit (NICU). METHODS A retrospective, matched case-control study in a tertiary NICU. Infants born between January 2009 and December 2019, <32 weeks' gestational age (GA) and/or birth weight (BW) <1500 g with pCMV infection were matched 1:1 with cytomegalovirus-(CMV)-negative infants by year of admission, gender, GA and BW. Primary outcome was death ≤36 weeks' postmenstrual age or bronchopulmonary dysplasia (BPD). Secondary outcomes were length of ventilation (LOV), length of stay (LOS) and neurodevelopmental impairment (NDI) at corrected age 1 and 2 years. RESULTS Forty-eight pCMV-positive infants (median GA 25.3 weeks, BW 695 g, age 58 days) were identified from 1659 infants (incidence 2.9%). The most common symptoms of pCMV infection were abdominal distension (43.8%), sepsis-like syndrome (29.2%), thrombocytopenia (60.5%) and conjugated hyperbilirubinemia (60.9%). Compared with controls, there were no significant differences in the composite outcome of death or BPD (56.3% vs. 37.5%; P = 0.1) or NDI at 1 and 2 years (51.9% vs. 44%; P = 0.8; 71.4% vs. 50%; P = 0.4). pCMV-positive infants had a significantly longer median LOV (23.5 vs. 12 days)* and LOS (140 vs. 110.5 days)*. Eleven (22.9%) infants received antivirals. Ten improved and 1 died. Two untreated infants died (1 from pCMV infection). CONCLUSIONS Clinically identifiable pCMV infections are significant and associated with increased respiratory support and prolonged hospital stay in vulnerable infants. pCMV screening and preventive measures against transmission merit consideration.*P < 0.05.

Abstract
BACKGROUND Preterm infants are at greater risk of developing postnatal cytomegalovirus (CMV) infection with serious symptoms. Breast milk is the main route of CMV transmission in populations with a high seroprevalence. OBJECTIVES This study aimed to investigate the clinical presentation and transmission of postnatal CMV (pCMV) infection via breast milk in preterm infants under the specific setting of our neonatal intensive care unit (NICU). METHODS The medical records of 147 preterm infants were reviewed retrospectively, and their clinical characteristics and outcomes were analyzed. Breast milk and infant urine samples were collected every two weeks until discharge, and the kinetics of CMV loads were evaluated using a polymerase chain reaction assay. RESULTS Seventeen infants (11.6%) were diagnosed with pCMV infection during the study period. In comparison between the pCMV and control groups, the mean birth weight was significantly lower in the pCMV group than in the control group (1084.1 ± 404.8 g vs. 1362.5 ± 553.8 g, P = 0.047). Four (23.5%) patients had leukocytopenia, six (35.3%) had neutropenia, three (17.6%) had thrombocytopenia, and two (11.8%) had hyperbilirubinemia in the pCMV group. Five patients were treated with antiviral agents, and their CMV load in the urine decreased after treatment. CMV loads peaked at 3-5 weeks in breast milk, whereas they peaked at 8-12 weeks of postnatal age in infants' urine. A comparison between the median CMV load in breast milk from the pCMV and control groups revealed a significant difference (P = 0.043). CONCLUSION Most preterm infants with pCMV infection present a favorable clinical course and outcomes. A high CMV viral load in breast milk is associated with transmission. Further studies are warranted to prevent transmission and severe pCMV infections in preterm infants.

Abstract
Background This study aimed to investigate the transmission of cytomegalovirus (CMV) via breast milk in low birth weight (LBW) and premature infants and its effects. Methods PubMed, Medline, Cochrane Library, and Embase were searched for studies (without language and time restriction) published before March 27, 2020, that examined the effect of CMV transmitted by breast milk on LBW and premature infants. The rates of breast milk-acquired CMV infection, CMV-related symptoms, and CMV-related sepsis-like syndrome (CMV-SLS) in LBW and premature infants were pooled from each study. Results Eighteen studies with 1920 LBW and premature infants were included. The pooled CMV infection rate from breast milk for infants fed untreated breast milk was significantly higher than those fed frozen breast milk [19.3, 95% confidence interval (CI) = 11.8–29.9% vs. 13.5, 95% CI = 8.0–22.0%, P < 0.01). Similarly, the pooled CMV infection rate for infants fed untreated breast milk was significantly higher than those with mixed feeding (P < 0.0001). The mixed feeding group had a significantly lower rate of CMV-related symptoms than the other groups (2.4%, P < 0.01). Conclusions These findings suggested a higher CMV infection rate in LBW or premature infants fed untreated breast milk than other feeding groups. Studies on the long-term outcomes of CMV infection transmitted from breast milk are needed to address the optimal feeding practice.

Abstract
Abstract
Objective This study aimed to investigate characteristics of human cytomegalovirus (HCMV) glycoprotein H (gH) genotypes in urine, throat swab, and serum from children and breast milk from children's mothers.
Methods Fresh urine samples, throat swabs, or serum samples from children and breast milk samples from children's mothers were collected for HCMV DNA detection. The positive samples of HCMV DNA were further detected by fluorescent quantitative polymerase chain reaction (PCR) with gH typing.
Results Of 1,703 HCMV DNA-positive samples, the highest proportion (83.3%, 85/102) of children aged between 21 days and 3 months was detected positive in breast milk samples (p = 0.002), and the highest proportion (70.5%, 110/156) of children aged above 3 months was detected positive in throat swab samples (p = 0.002). HCMV in throat swab specimens is mainly high copy (p < 0.0001), and low-copy HCMV is prevalent in breast specimens (p < 0.0001). Among them, 1,059 samples were identified as gH1 genotype, 530 samples were gH2, and 114 samples were coinfection (gH1/2). There had the highest gH2 rates (32.3%) and lowest gH1 (61.0%) rates in urine samples (p = 0.041), whereas the highest gH1 rates (71.6%) and lowest gH2 rates (19.6%) were found in breast milk samples (p = 0.032). Concerning age groups, patients aged between 21 days and 3 months had the highest gH1 proportion (p = 0.017), while patients aged above 3 months had the highest gH1 and gH2 HCMV coinfection proportion (p = 0.002). Among 43 pairs of maternal and child samples corresponding to positive samples, gH genotype of 35 pairs of samples was consistent with a rate of 81.4%.
Conclusion gH1 is the predominant genotype of HCMV in each kind of sample in China. However, the distribution of the HCMV gH genotype is different among different samples.

Abstract
OBJECTIVE Very low birth weight preterm infants are at risk for life-threatening infections in the NICU. Breast milk protects against infections but carries the risk of infection by cytomegalovirus (CMV) shed in mother's milk. Lactoferrin is a breast milk and saliva protein with potent neutralizing activity against CMV. STUDY DESIGN VLBW, maternal breast milk fed infants in the NICU and their lactating mothers were enrolled and followed for 3 months/discharge. Breast milk and infant saliva samples were collected biweekly. Maternal CMV status was determined on breast milk. CMV was measured using quantitative polymerase chain reaction and lactoferrin by enzyme-linked immunosorbent assay. RESULTS In an in vitro neutralization assay, the IC90 of purified human lactoferrin against CMV was 2.08 ng/mL. Bovine lactoferrins were more potent, IC90s > 10-fold higher. Lactoferrin was detected in all breast milk (median: 3.3 × 106 ng/mL) and saliva (median: 84.4 ng/swab) samples. Median CMV load in breast milk was 893 copies/mL. There was no correlation between breast milk lactoferrin concentration and CMV load. Five infants acquired postnatal CMV. There was no difference in saliva or breast milk lactoferrin concentration for mother-infant pairs and postnatal CMV acquisition. CONCLUSION Lactoferrin neutralizes CMV in vitro, but concentrations in breast milk and saliva are likely too low for effective neutralization in vivo.

Abstract
Providing adequate amounts of all essential macro- and micronutrients to preterm infants during the period of extraordinarily rapid growth from 24 to 34 weeks' postmenstrual age to achieve growth as in utero is challenging yet important, since early growth restriction and suboptimal neonatal nutrition have been identified as risk factors for adverse long-term development. Along with now well-established early parenteral nutrition, this review emphasizes enteral nutrition, which should be started early and rapidly increased. To minimize the side effects of parenteral nutrition and improve outcomes, early full enteral nutrition based on expressed mothers' own milk is an important goal. Although neonatal nutrition has improved in recent decades, existing knowledge about, for example, the optimal composition and duration of parenteral nutrition, practical aspects of the transition to full enteral nutrition or the need for breast milk fortification is limited and intensively discussed. Therefore, further prospective studies on various aspects of preterm infant feeding are needed, especially with regard to the effects on long-term outcomes. This narrative review will summarize currently available and still missing evidence regarding optimal preterm infant nutrition, with emphasis on enteral nutrition and early postnatal growth, and deduce a practical approach.

Long-term Outcomes after Postnatal Cytomegalovirus Infection in Low Birthweight Preterm Infants: A Systematic Review. Pediatr Infect Dis J 2021; 40:571-581. [PMID: 33902071 DOI: 10.1097/inf.0000000000003072] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/26/2022]
Abstract
BACKGROUND Cytomegalovirus (CMV) is the most common viral infection seen in newborns. Although postnatally acquired CMV (pCMV) infection rarely results in serious manifestations in term infants, preterm infants can develop severe clinical illness. However, the long-term implications of pCMV infection of preterm infants are unknown. Few robust studies on long-term outcomes of pCMV infection have been performed, and those reported often present conflicting results. Our objective was to assess the long-term outcomes for low birthweight (LBW) preterm infants after pCMV infection. METHODS A systematic review of English and non-English articles using MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, and Web of Science was conducted. Search strategies included a mix of keywords and database-specific subject headings for CMV and LBW infants. Editorials, comments, reviews and animal-only studies were excluded. Case reports, observational, experimental and randomized controlled trials that examined pCMV in preterm or VLBW infants and long-term (>1 month) impact of pCMV were included. RESULTS pCMV infection in preterm infants is associated with increased risk for pulmonary and neurologic complications and increases length of stay. There is less evidence to suggest that pCMV is associated with necrotizing enterocolitis, ophthalmologic, audiologic and anthropomorphic complications in preterm infants. CONCLUSIONS Preterm infants with pCMV, especially those with symptomatic infection, may have long-term pulmonary and neurodevelopmental morbidity compared with their pCMV negative counterparts. Our results highlight the importance of pCMV detection and prevention in preterm infants in the neonatal intensive care unit. Large prospective studies are needed to fully define outcomes and determine if treatment improves outcomes.

Abstract
BACKGROUND We performed a systematic review and meta-analysis to evaluate the incidence of breast milk-acquired cytomegalovirus (CMV) infection in preterm infants born to CMV-seropositive mothers. METHODS PubMed, Embase, and Cochrane Library databases were searched using the terms: ("breast feeding" or "breast milk" or "human milk" or "breast") and ("HCMV" or "cytomegalovirus") and ("infant, extremely premature" or "premature birth" or "newborn" or "neonate" or "low birth weight" or "very low birth weight" or "premature" or "preterm infant"). Studies that had information on CMV status and breast feeding were included in the meta-analysis. RESULTS A total of 2,502 newborns from 19 studies were included in this meta-analysis. The rate of postnatally acquired CMV infection among breastfed infants with CMV-seropositive mothers was 16.5% (95% confidence interval [CI], 0.10-0.26; P < 0.001). The infection rate was 26% with fresh breast milk, 8% with a combined diet of fresh and freeze-thawed breast milk, and 11% with freeze-thawed breast milk. Among cases where the CMV status of breast milk was determined, CMV shedding into breast milk occurred in 80.5% (95% CI, 0.71-0.87; P < 0.001) of CMV seropositive mothers. The breast milk-acquired CMV infection rate among infants fed CMV-positive breast milk was 20.7% (95% CI, 0.14-0.30; P < 0.001). CONCLUSION This meta-analysis examined the rate of breast milk-acquired CMV infections in preterm infants with CMV-seropositive mothers; the CMV infection rate was higher in preterm infants fed fresh breast milk. Until further data are available, we cautiously suggest the use of freeze-thawed breast milk, rather than fresh breast milk, for preterm infants or very low birth weight infants.

Literature Review and an Italian Hospital Experience about Post-Natal CMV Infection Acquired by Breast-Feeding in Very Low and/or Extremely Low Birth Weight Infants. Nutrients 2021; 13:660.

Abstract
Breastfeeding is recommended for all neonates due to a known variety of beneficial effects, but infants can be infected by cell-associated bacteria and viruses from breast milk, such as cytomegalovirus (CMV). The majority of CMV-seropositive breastfeeding women have a viral, self-restricted reactivation, can shed the virus in the milk for about 12 weeks after delivery, and can transmit the infection to their offspring. Post-natal CMV-infected term infants are mainly asymptomatic, while very low birth weight (VLBW, <1500 g) and extremely low birth weight (ELBW, <1000 g) infants may present with severe disease, short-term sequelae ranging from abnormalities in laboratory indexes to sepsis-like syndrome, and long-term sequelae such as developmental problems. Thus, the use of thermally treated maternal milk for VLBW/ELBW infants may be indicated to prevent/reduce the risk of CMV transmission. Different techniques, with varying efficacy in eradicating CMV and maintaining the activity of biological compounds in milk are available: long/short pasteurization, freeze-thawing, the use of microwaves, and ultraviolet-C irradiation. In our NICU, the use of maternal raw milk is always strongly recommended for term/preterm infants, but to reduce risk of CMV transmission, freeze-thawing mother's own milk is used in neonates with GA ≤ 30 weeks or/and weight ≤ 1000 g, usually regardless of serological maternal condition, as CMV screening is not routinely offered to pregnant women and the milk of seroimmune mothers is not evaluated for CMV reactivation, as its rate is similar to seroprevalence. Over the last 4 years, we had 10 VLBW/ELBW newborns in our NICU with late-onset sepsis and negative cultures. In these cases, the research of CMV DNA in neonatal urine or saliva, for the diagnosis of post-natal symptomatic infection (once congenital transmission has been excluded) may be useful and not invasive. The take-home message we would like to share is that acquired CMV infection should be considered in VLBW/ELBW infants breastfed by seropositive mothers and presenting severe symptoms-particularly sepsis with negative cultures. This could allow pediatricians to make better-quality diagnoses, perform supportive therapy, provide antiviral treatment if needed, or establish a "pre-emptive" therapy for these high-risk neonates.

Abstract
To determine the status of human cytomegalovirus (HCMV) infection in human milk in China, a total of 510 human milk samples obtained from three provinces, including 211 donor human milk samples from human milk banks and 299 milk samples obtained from the mothers of premature infants, were tested to detect HCMV DNA. Overall, 46.4% of the donated milk samples and 59.2% of the samples obtained from mothers of premature infants were positive for HCMV DNA. The concentration of HCMV DNA was approximately 103 -104 copies/ml in the HCMV-DNA-positive human milk samples. Based on the nucleotide sequence of a 299- to 305-bp fragment of the glycoprotein B (gB) gene, three HCMV genotypes (gB1, gB2 and gB3) were identified in human milk samples. Mixed infection with genotypes gB1 and gB3 was also found in four milk samples from mothers. Genotype gB1 was the predominant genotype in the HCMV-DNA-positive human milk samples, and it could be subdivided into three lineages. There were also some characteristic nucleotides and amino acids in the three HCMV genotypes, which were helpful for distinguishing the genotypes. This is the first study to clarify the HCMV infection status and genetic characteristics of human milk obtained from banks in China, which will be helpful in preventing postnatal HCMV infections and ensuring the safety of human milk banks.

Abstract
Background Necrotizing enterocolitis (NEC) is the leading cause of death among preterm infants born at < 30 weeks’ gestation. The incidence of NEC is reduced when infants are fed human milk. However, in many neonatal intensive care units (NICUs), it is standard practice to freeze and/or pasteurize human milk, which deactivates bioactive components that may offer additional protective benefits. Indeed, our pilot study showed that one feed of fresh mother’s own milk per day was safe, feasible, and can reduce morbidity in preterm infants. To further evaluate the benefits of fresh human milk in the NICU, a randomized controlled trial is needed. Methods Our prospective multicenter, double-blinded, randomized, controlled trial will include infants born at < 30 weeks’ gestation and admitted to one of 29 tertiary NICUs in China. Infants in the intervention (fresh human milk) group (n = 1549) will receive at least two feeds of fresh human milk (i.e., within 4 h of expression) per day from the time of enrollment until 32 weeks’ corrected age or discharge to home. Infants in the control group (n = 1549) will receive previously frozen human milk following the current standard protocols. Following informed consent, enrolled infants will be randomly allocated to the control or fresh human milk groups. The primary outcome is the composite outcome mortality or NEC ≥ stage 2 at 32 weeks’ corrected age, and the secondary outcomes are mortality, NEC ≥ stage 2, NEC needing surgery, late-onset sepsis, retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), weight gain, change in weight, increase in length, increase in head circumference, time to full enteral feeds, and finally, the number and type of critical incident reports, including feeding errors. Discussion Our double-blinded, randomized, controlled trial aims to examine whether fresh human milk can improve infant outcomes. The results of this study will impact both Chinese and international medical practice and feeding policy for preterm infants. In addition, data from our study will inform changes in health policy in NICUs across China, such that mothers are encouraged to enter the NICU and express fresh milk for their infants.

Abstract
Breast Milk (BM) is the best source of nutrition for newborns, especially if premature. In fact, its beneficial impact on short- and the long-term neonatal outcome has was deeply described. Unfortunately, BM could not be always so safe, especially due to the possible presence of maternal viruses that can be shed and transferred to the breastfed neonate. Among these, Cytomegalovirus (CMV) can potentially lead to a serious and acute illness, mostly in case of low gestational age. Some studies also report the association of CMV-acquired infection to an increased risk of structural and functional brain modifications and neurological impairment. Due to these reasons, a strategy to remove CMV from BM with a minimal or absent impact on its beneficial components would be desirable. Up to now, pasteurization, freezing, ultraviolet- C or microwave irradiation are the available techniques; they show different levels of efficacy and variable effects on BM composition, even if many studies are still needed to fully clarify these implications. In this review, we provide an update of the current evidence about these topics. We focus on the factors promoting CMV shedding through BM; moreover, the possible occurrence of a severe disease in preterm neonates is also described. Finally, we investigate the potential effects showed on BM properties by the strategies that prevent or reduce viral transmission, therefore influencing newborns' health, and the new techniques which could show a relevant role in the next future, such as metabolomics.

Abstract
AIM There are no specific recommendations for using a mother's fresh milk for her preterm infant. We reviewed the available evidence on its collection, storage and administration. METHODS The working group of the French Neonatal Society on fresh human milk use in preterm infants searched the MEDLINE database and Cochrane Library up to June 2017 for papers published in English or French. They specifically analysed 282 papers providing information on prospective, retrospective and clinical studies and examined guidelines from various countries. RESULTS The review concluded that fresh mother's own milk should be favoured in accordance with the latest recommendations. However, it must be carried out under stringent conditions so that the expected benefits are not offset by risks related to different practices. The working group has summarised the best conditions for feeding preterm infants with human milk, balancing high nutritional and immunological quality with adequate virological and bacteriological safety. Professionals must provide parents with the necessary conditions to establish breastfeeding, together with specific and strong support. CONCLUSION Based on their review, the working group has made specific recommendations for using fresh mother's own milk under careful conditions, so that the expected benefits are not offset by risks related to practices.

Abstract
Breast milk is considered ideal food for premature infants, but it can also be the main source of cytomegalovirus (CMV) infection in premature infants. CMV infection may cause serious clinical symptoms, such as sepsis-like syndrome, thrombocytopenia, neutropenia, jaundice, hepatitis, and pneumonitis. This article reviews the research advances in symptoms, treatment strategies, prognosis and the prevention of breast milk-acquired CMV infection in premature infants.
