Regulation of adipogenesis by exosomal milk miRNA

Abbas MA, Al-Saigh NN, Saqallah FG

Rev Endocr Metab Disord, 2023 Apr;24(2):297-316.
PMID: 36692804 DOI: 10.1007/s11154-023-09788-3

Milk is a rich source of miRNA packaged in exosomes. Evidence for the systemic uptake and tissue distribution of milk exosomes was reported in newborn and adult humans and animals. Breastfeeding in infants was associated with a reduced risk of obesity. Numerous adipogenesis-related miRNAs have been detected in human milk exosomes. It has been demonstrated that ingested exosomal milk miRNAs may alter gene expression in offspring to regulate their metabolism and growth. In humans, consumption of other species' milk, such as cows and goats, is continued through adulthood. Since miRNAs are conserved, the concern of cross-species transfer of adipogenic miRNA has been raised in recent years, and the increase in obesity worldwide was attributed partially to dairy milk consumption by humans. However, evidence is still weak. Research emphasizes the need for an adequate number of exosomal milk's miRNAs to reach the target cell for biological action to be achieved. It was reported that obese women's milk had less miRNA-148a and miRNA-30b, which may affect the fat acquisition of their babies. Some exosomal milk miRNAs, such as miRNA-29, miRNA-148, miRNA-30b and miRNA-125b, may have epigenetic effects on milk recipients. Moreover, the ability of milk exosomes to cross the gastrointestinal barrier makes them a promising oral drug delivery tool. Yet, exosomes may also be tagged with specific ligands which target certain tissues. Thus, milk exosomes can be engineered and loaded with certain miRNAs responsible for adipocyte differentiation, conversion, or browning. Modifications in the miRNA cargo of exosomes can benefit human health and be an alternative to traditional drugs.

Fulltext Nutritional practices and growth of preterm infants in two neonatal units in the UK and Malaysia: a prospective exploratory study

Abdul Hamid H, Szatkowski L, Budge H, Cheah FC, Ojha S

BMJ Paediatr Open, 2021;5(1):e001153.
PMID: 34514178 DOI: 10.1136/bmjpo-2021-001153

Objective: To explore differences in nutritional practices and growth outcomes among preterm infants in neonatal units in Malaysia and the UK.
Design: Prospective exploratory study of infants born at <34 weeks gestational age (GA).
Setting: Two neonatal units, one in Malaysia and one in the UK (May 2019 to March 2020).
Methods: Data collected from birth until discharge and compared between units.
Results: From 100 infants included, median GA (IQR) was 31 (30-33) and mean±SD birth weight was 1549±444 g. There were more small-for-gestational age infants in Malaysian unit: 12/50 (24%) vs UK: 3/50 (6%), p=0.012 and more morbidities. More Malaysian infants received breast milk (Malaysia: 49 (98%) vs UK: 38 (76%), p=0.001), fortified breast milk (Malaysia: 43 (86%) vs UK: 13 (26%), p<0.001) and exclusive breast milk at discharge (Malaysia: 26 (52%) vs UK: 16 (32%), p=0.043). There was higher parenteral nutrition use among Malaysian infants (40/50 (80%)) vs UK (19/50 (38%)) (p<0.001) with higher protein intake (mean±SD Malaysia: 3.0±0.5 vs UK: 2.7±0.6 g/kg/d, p=0.004) in weeks 1-4 and smaller cumulative protein deficits (mean±SD Malaysia: 11.4±6.1 vs UK: 15.4±8.0 g/kg, p=0.006). There were no significant differences in short-term growth between units and more than half of the infants in both units had ≥1.28 changes in weight-for-age Z-score at discharge (p=0.841).
Conclusions: An exploratory comparison of practices showed differences in patient characteristics and nutritional practices which impacted growth. Future studies with larger sample sizes and detailed analysis of maternal characteristics and infants' outcomes are needed for improving care of preterm infants in all settings.

PMID: 37708192 DOI: 10.1371/journal.pone.0290311

Informal human milk exchange is the practice of donating and receiving expressed human milk based on mutual consent between the donor and receiver in the need of human milk for infants below 2 years old. Main concerns related to informal human milk exchange is related to milk siblings and safety handling of the expressed breastmilk. Even though there are countries which have policies and procedures related to human milk bank, informal milk exchange has not been given much attention. Compared to human milk bank, informal human milk exchange is not regulated. This study aims to identify the system focused on personalized breastfeeding tracking and monitoring, online discussion forum, web-based consultation, and breastfeeding station locator. Review of current applications in supporting breastfeeding practices was conducted based on the PRISMA-ScR framework. A literature search was conducted in Scopus and Google Scholar databases to identify articles published in English or Malay and containing systems/applications related to breastfeeding, milk sharing, milk exchange, milk siblings/kinship within the societal context. According to the scoping review, current scientific publications mostly focused on breast milk, breastfeeding, and milk banking concerns, with recurring themes including social reasons, lactation insufficiency, and unsolved nursing problems. These themes highlight the complexities and complexities of informal human milk exchange practices. Two reviewers screened the articles, and the data were extracted and narratively synthesized. During the primary database search, 360 articles were found based on the related titles, abstracts, and keywords. Seventy eight met the inclusion criteria and were finalized in this review. We found that most scholarly works focused on breast milk, breastfeeding and milk banking challenges and issues with recurrent themes i.e., societies, lactation inadequacy and unresolved nursing problems. Based on our literature search and to the best of our knowledge, there is no recent scoping reviews which focuses on technology-based approaches on informal human milk exchange. Findings from this scoping review is important for advancing research and practice in this field, as well as improving outcomes for individuals and families affected by informal human milk exchange.

MyJurnal

The knowledge, attitude and practice of breastfeeding among young mothers during pre-Baby Friendly Hospital Initiative implementation was conducted at seven private hospitals in Malaysia. A structured interviewer administered questionnaire was given to all mothers (n=Z52) visiting the antenatal/postnatal clinic of the hospitals. The main respondents were Malays (57.5%) and Chinese (35%) . For most mothers, breastfeeding was combined with supplementary feeds of formula milk, with only 30% breastfed exclusively. The majority of mothers knew that breast-milk contained antibodies and can prevent illness, however many were unaware of breastfeeding's contraceptive effect if practised exclusively. Most mothers did not relate breastfeeding as being environmental friendly. Generally, there was no knowledge gained from the experience of having more children with reference to breastfeeding. Most mothers were influenced by their own beliefs regarding choice of feeding method. Therefore, a mother was empowered with the knowledge of all practical aspects of breastfeeding, it would encourage her to breastfeed her baby.

Fulltext Qualitative dataset on UPLC-QTOF/MS tentative identification of phytochemicals from bioactive extract of Ipomoea mauritiana Jacq

Alam I, Forid MS, Roney M, Aluwi MFFM, Huq AM

Data Brief, 2021 Apr;35:106839.
PMID: 33659597 DOI: 10.1016/j.dib.2021.106839

The current data report describes the predictive identification of phytochemical constituents in the bioactive extract of Ipomoea mauritiana (IM) whole plant. For several formulations this plant was commonly used as 'Vidari' for Ayurvedic medicine. Traditionally, IM tubers are used to alleviate spinal cord pain, improve breast milk, as a tonic, increase sperm count and treating jaundice. The methanol extract can potentially scavenge free radicals and possess antibacterial activity that could be correlated with its chemical composition. So it is crucial to identify the major compounds of IM. An ultra-performance liquid chromatography coupled electrospray ionization quadrupole time-of-flight mass spectrometry (UPLC-ESI-QTOF/MS) method was adopted to detect the flavonoids, saponins, alkaloids, terpenoids in IM methanol extract. Data presented here is related to a published work Antioxidant and antibacterial activity of Ipomoea mauritiana Jacq.: A traditionally used medicinal plant in Bangladesh (Alam et al., 2020). Secondary metabolites were analyzed by the comparison of the mass fragmentation arrangements with Waters UNIFI library that enables for positive identification of the compounds based on the spectral match.

Electrolyte profile of Malaysian mothers' milk

Alaudeen S, Muslim N, Faridah K, Azman A, Arshat H

Malays J Reprod Health, 1988 Dec;6(2):102-7.
PMID: 12342169

PIP: The influence of socioeconomic status (ethnicity, income and parity) on electrolyte composition (sodium and potassium) in human milk is little known. We have thus quantitatively analyzed approximately 700 samples of milk (1-90 days postpartum) obtained from healthy Malaysian mothers' (Malay, Chinese and Indians) of full term infants. Results show that the mean concentration (mmol/l) of sodium is highest (48.2+or-1.7, Mean+or-SEM) in the Malaysian mothers' colostrum and this value decreased by 30% in their transitional milk and remained constant throughout subsequent days of lactation (mature milk). Ethnically, it is found that the level of sodium in colostrum of Malay and Chinese mothers were similar while the Indian mothers' colostrum showed apparently higher value (52.7+or-3.4 mmol/l) that is statistically insignificant. The transitional milk of all 3 ethnic groups studied exhibited similar levels of sodium. On subsequent days of lactation (mature milk) the Malay mothers exhibited lowest concentration (25.9+or-2.6 mmol/l) of sodium that is significantly (P0.05) different from that of Chinese and Indian mothers. Income and parity do not significantly affect the sodium level in Malaysian mothers' milk during all stages of lactation studied. The level of potassium, however did not change significantly with days of lactation. Like sodium, potassium too was not influenced by income and parity. (Author's).

Creating religiously compliant milk banks in the Muslim world: a commentary

Alnakshabandi K, Fiester A

Paediatr Int Child Health, 2016 Feb;36(1):4-6.
PMID: 26750779 DOI: 10.1080/20469047.2015.1110336

Human milk banks are vital for providing donor milk to infants for whom there are maternal or postnatal barriers to the mother's own milk. Although more than 35 countries have active milk banks, not one of those is a Muslim country.(1) Despite widespread support for breastfeeding across the Muslim world, religious constraints surrounding milk-sharing have created challenging barriers to the creation of milk banks. The religious objection centres around the Islamic tenet that consuming human milk builds a kinship bond between individuals who have consumed the same woman's milk which prohibits future marriage between the 'milk-brothers and sisters.' While a small-scale, experimental 'milk exchange' programme has been attempted in two Muslim countries (Kuwait and Malaysia), the only proposed milk bank in the Muslim world was a pilot programme in Turkey that was halted because of religious concerns. The problem with milk banking is the step in the process during which the milk from individual donors is pooled and de-identified, making it impossible to trace its origins and acknowledge the newly formed kinship relationship. To meet the need for Muslim children to be able to access human milk while remaining compliant with the prevalent understanding of Islamic doctrine on milk-sharing, we propose a new approach to milk banking that we term the Conditional Identified Milk Banking System (CIMBS). In this new system, both the donor's and recipient's identities are accessible to all parties through a voluntary registry, and the milk-pooling is limited to three milk donors. Based on recent survey data, we believe that there would be receptivity among practicing Muslims and religious leaders to this alternative approach.

Fatty liver in a two days old neonate

Arivalagan P, Husain MS, Subramaniam K, Kaslan MRM

Med J Malaysia, 2019 Oct;74(5):454-455.
PMID: 31649231

Neonatal death due to inborn error of metabolism (IEM) is rare in Malaysia. We report a sudden neonate death just a few hours after being discharged from the hospital. The deceased was a two-day-old baby boy and was asymptomatic until his demise. He was fed with expressed breast milk and formula milk. Autopsy revealed fatty changes of the liver and an enlarged heart. Laboratory investigation confirmed very long chain Acyl-CoA dehydrogenase deficiency which resulted in his death. Autopsy of sudden unexpected death in neonate should include investigation for inborn error of metabolism. Fatty liver and enlarged heart could give a clue for the diagnosis.

This is a cross-sectional study on 218 pregnant mothers in an urban government Hospital.The study aimed to assess knowledge, attitudes and sources of information on breastfeeding. The results could be utilised to promote breastfeeding. Almost all the respondents (96.8%) intended to breastfeed their newborns. Most of them (74.8%) were knowledgeable about breastfeeding i.e. colostrum and breast milk was the best food, good for resistance against disease and allergy, filling up stomach easily, helpful in teeth development and maternal recovery after birth, increased bonding, was easy and economical. The two main misconceptions were mothers would stop breastfeeding when infant or mother was sick, and giving clear fluid to the exclusively breastfed infants to prevent dehydration. Most mothers (83.9%) responded positively towards breastfeeding i.e. it was easier than infant formula, had no negative effect on marital relationship or family care, would commence breastfeeding straight after delivery, agreeable to the banning of bottles and teats in hospital and they would not stop breastfeeding even if husband discouraged them. Only 56.9% of the mothers believed they could breastfeed their babies with modesty anywhere. The main sources of information were attained from the mass media (34.9%), antenatal class (32.1%) and other mothers with breastfeeding experiences.

Fulltext Contaminated milk is a common cause of necrotising enterocolitis: A hypothesis

Boo NY

Malays J Pathol, 2016 Dec;38(3):223-227.
PMID: 28028291 MyJurnal

Necrotising enterocolitis (NEC) is the most commonly acquired gastrointestinal disease of neonates, particularly the very preterm (gestation <32 weeks) and/or very low birth weight (<1500g). It is associated with high morbidity and mortality. Despite improvement in neonatal care and increased use of expressed breast milk (EBM), the incidence remains high in many neonatal intensive care units (NICU), and even shows increasing trend in some countries. Numerous studies have pointed to the infective nature of NEC. Some investigators have reported an increase in the incidence of NEC in their NICU when the percentage of infants with pathogens isolated from their gut increased, and decreased when gut colonisation rate was low. Both bacteria and viruses have been reported to be associated with outbreaks of NEC. The majority (>90%) of the NEC cases occurred in neonates on enteral feeding. Studies have shown that milk (whether EBM or formula) fed to neonates was not sterile and were further contaminated during collection, transport, storage and/or feeding. Other investigators have reported a reduction in the incidence of NEC when they improved infection control measures and hygienic procedures in handling milk. It is, therefore, hypothesised that the most common cause of NEC is due to the feeding of neonates, particularly the vulnerable very preterm small neonates, with milk heavily contaminated during collection at source, transport, storage and/or feeding. Because of the immaturity of the immune system of the neonates, excessive inflammatory response to the pathogen load in the gut leads to the pathogenesis of NEC.

PMID: 11740876

The objective of this study was to compare the rates of bacterial contamination of expressed breast milk (EBM) obtained by manual expression and breast pumps in mothers of very low birthweight (VLBW) infants (<1501 g). This was a randomized, controlled study carried out on 28 mothers of such babies and 92 specimens of EBM were collected: 41 specimens from 13 mothers assigned to the manual group and 51 specimens from 15 mothers in the breast-pump group. EBM was cultured quantitatively by the Miles and Misra method. Breast milk expressed by breast pumps (86.3% or 44/51 specimens) had a significantly higher rate of bacterial contamination than milk expressed by the manual method (61.0% or 25/41 specimens) (P= 0.005). When breast milk was expressed in the hospital, there was no significant difference in contamination rates between the two methods. When breast milk was expressed at home, the rates of bacterial contamination by staphylococci (P= 0.003) and Gram-negative bacilli (P= 0.002) were significantly higher in the breast-pump group than the manual group. In conclusion, the rate of bacterial contamination of EBM of mothers of VLBW infants was high, especially when EBM was obtained by the breast pump or when expression was carried out at home.

Fulltext Challenges experienced by induced lactation women in Malaysia: An exploratory qualitative study

Che Abdul Rahim N, Sulaiman Z, Ismail TAT

PLoS One, 2024;19(1):e0291758.
PMID: 38277383 DOI: 10.1371/journal.pone.0291758

BACKGROUND: Induction of lactation occurs when breast milk is produced in a human (woman), without going through the process of pregnancy and delivery. Efforts to produce milk by women who had never been pregnant and give birth are not easy. According to the many who have attempted it, it is far more arduous a task than initiating postpartum lactation, but it is possible and worth the effort.
RESEARCH AIM: This study aimed to explore and understand the challenges for women during induced lactation in Malaysia.
METHODS: This qualitative study was done in 2017 and utilized in-depth interview among women who induced lactation in five states based on five regions in Malaysia [Central Region (Selangor), Northern Region (Penang), Southern Region (Johor), East Coast Region (Kelantan), Malaysia Borneo (Sabah)]. All interviews were consented, audio-recorded then transcribed verbatim, followed by identification of main themes.
RESULTS: Data saturation was achieved after interviewing a total of 23 induced lactation women. Data synthesized using thematic analysis revealed six themes describing the main challenges during the induction process were (1) health condition, (2) work commitment, (3) overexertion, (4) not eligible to take leave, (5) inability to follow the treatment plan, and (6) difficulty attaching the adopted baby to initiate breastfeeding during induced lactation process.
CONCLUSIONS: The challenges faced by women during the process of induced lactation were complex and the induced lactation process requires considerable dedication and determination. The findings of this research will help other women and their spouses/partners comprehend the challenges, obstacles, and support that are needed along the induced lactation process. The Government and other stakeholders have roles in more efforts and programs to help these mothers breastfeed their adoptive child and make them feel more accomplished as women and mothers.

A survey among healthcare professionals from seven countries reported diverse nutritional practices of late preterm infants

Cheang HK, Yeung CY, Cheah I, Tjipta GD, Lubis BM, Garza-Bulnes R, et al.

Acta Paediatr, 2022 Jul;111(7):1362-1371.
PMID: 35340076 DOI: 10.1111/apa.16344

AIM: To gain insight into nutritional practices and expected growth outcomes of infants born between 34 and 36 gestational weeks defined as late preterm infants (LPT).
METHODS: An anonymous online survey among paediatricians and neonatologists from Bangladesh, Indonesia, Mexico, Nigeria, Malaysia, Singapore and Taiwan was conducted from March until October 2020. The questionnaire consisted of 40 questions on the nutritional management and expected growth outcomes of LPT in and after-hospital care.
RESULTS: Healthcare professionals from low to high Human Development (HDI) countries (n = 322) and very high HDI countries (n = 169) participated in the survey. Human milk was the preferred feeding, resulting in an adequate growth of LPT (weight, length and occipitofrontal circumference), according to a majority of respondents (low to high HDI, 179/265, 68% vs. very high HDI, 73/143, 51%; p = 0.002). The expected growth outcome was higher after-hospital discharge. Less than half of healthcare professionals started enteral feeding during the 1st hour of life. Lactation difficulties, limited access to human milk fortifiers and donor human milk, especially among low to high HDI countries, were reported as major hurdles.
CONCLUSION: Human milk is the first feeding choice for LPT. The diverse opinions on nutritional practices and expected growth outcomes among healthcare professionals indicate the necessity to develop general nutritional guidelines for LPT.

Fulltext Skeletal Effects of Early-Life Exposure to Soy Isoflavones-A Review of Evidence From Rodent Models

Chin KY, Pang KL

Front Pediatr, 2020;8:563.
PMID: 33072660 DOI: 10.3389/fped.2020.00563

Isoflavones are dietary phytoestrogens commonly found in soy-based products. The widespread presence of isoflavones in soy infant formula and breast milk may have long-lasting effects on the development of sex hormone-sensitive organs like the skeleton. Animal early-life programming models are suitable for testing the skeletal effects of pre- and neonatal exposure of soy isoflavones. This review aims to collate the impacts of early-life exposure of soy isoflavones as evidenced in animal models. The isoflavones previously studied include daidzein, genistein, or a combination of both. They were administered to rodent pups during the first few days postnatal, but prolonged exposure had also been studied. The skeletal effects were observed when the animals reached sexual maturity or after castration to induce bone loss. In general, neonatal exposure to soy isoflavones exerted beneficial effects on the skeletal system of female rodents, but the effects on male rodents seem to depend on the time of exposure and require further examinations. It might also protect the animals against bone loss due to ovariectomy at adulthood but not upon orchidectomy. The potential benefits of isoflavones on the skeletal system should be interpreted together with its non-skeletal effects in the assessment of its safety and impacts.

The thiamine content of human milk in Malaya. II. The effect of the administration of supplementary thiamine on the thiamine level of human milk

Chow AY, Simpson IA

J Trop Pediatr (Lond), 1956 Sep;2(2):69-76.
PMID: 24544134

(1) The effect has been studied of the oral administration of supplementary thiamine on the thiamine content of milk from sixteen women, whose initial thiamine content was low ; and of the parenteral administration of thiamine to ten women, some of whom initially showed mild, clinical symptoms of beriberi.
(2) The response in the milk content of thiamine to supplementary thiamine, administered either orally or by injection, showed marked variation in different women. While comparatively small doses taken by mouth evoked a marked response in some women, fairly large doses administered by injection failed to produce much response in others.
(3) In some women, a marked increase in the thiamine content of their milk occurred soon after the administration of thiamine, either orally or parenterally. In others, the response was slow and meagre.
(4) The highest thiamine level obtained in a sample of milk was 38.9 ug./100 ml., after the injection, twice daily, of 20 mg. thiamine for six days — a total intake of 240 mg. of thiamine parenterally. The initial milk thiamine level in this case was 2.3 ug./100 ml., but had increased to 16.2ug./100 ml., by the supply of a good diet alone, before the course of injections was commenced.
(5) It would appear, that, in cases where the thiamine content of the milk is low, initial parenteral administration of thiamine must be supplemented by a continued intake of additional thiamine, if a satisfactory level of thiamine in the milk is to be maintained.

Fulltext The trans fatty acid content in human milk and its association with maternal diet among lactating mothers in Malaysia

Daud AZ, Mohd-Esa N, Azlan A, Chan YM

PMID: 23945414 DOI: 10.6133/apjcn.2013.22.3.09

Excessive intake of trans fatty acids (TFA) could reduce the fat density of human milk and impair the desaturation of essential fatty acids. Because the mammary glands are unable to synthesize TFA, it is likely that the TFA in human milk come from dietary intake. Thus, the aim of this study was to investigate the sources of TFA intake for lactating mothers in one of the urban areas in Selangor. In this cross-sectional study, anthropometric measurements, FFQ including 7 food groups and dietary consumption data were collected from 101 lactating mothers. Five major TFA isomers (palmitoelaidic acid (16:1t9), petroselaidic acid (18:1t6), elaidic acid (18:1t9), vaccenic acid (18:1t11) and linoelaidic acid (18:2t9,12) in human milk were measured by gas chromatography (GC). The relationship between food consumption and TFA levels was assessed using the non-parametric Spearman's rho test. The TFA content in human milk was 2.94±0.96 (SEM) % fatty acid; this is considered low, as it is lower than 4%. The most abundant TFA isomer was linoelaidic acid (1.44±0.60% fatty acid). A sub-experiment (analyzing 3 days of composite food consumption) was conducted with 18 lactating mothers, and the results showed that linoelaidic acid was the most common TFA consumed (0.07±0.01 g/100 g food). Only 10 food items had an effect on the total TFA level and the isomers found in human milk. No association was found between TFA consumption and the TFA level in human milk.

Inulin-based prebiotics are non-digestible polysaccharides that influence the composition of the gut microbiota in infants and children, notably eliciting a bifidogenic effect with high short chain fatty acid levels. Inulin, a generic term that comprises β-(2,1)-linked linear fructans, is typically isolated from the chicory plant root, and derivatives such as oligofructose and long chain inulin appear to have different physiological properties. The first 1000 days of a child's life are increasingly recognized as a critical timeframe for health also into adulthood, whereby nutrition plays a key role. There is an ever increasing association between nutrition and gut microbiota composition and development, with life health status of an individual. This review summarizes the latest knowledge in the infant gut microbiota from preterms to healthy newborns, as well as in malnourished children in developing countries. The impact of inulin or mixtures thereof on infants, toddlers and young children with respect to intestinal function and immunity in general, is reviewed. Possible benefits of prebiotics to support the gut microbiome of malnourished infants and children, especially those with infections in the developing world, are considered, as well as for the pregnant mothers health. Importantly, novel insights in metabolic programming are covered, which are being increasing recognized for remarkable impact on long term offspring health, and eventual potential beneficial role of prebiotic inulins. Overall increasing findings prompt the potential for gut microbiota-based therapy to support health or prevent the development of certain diseases from conception to adulthood where inulin prebiotics may play a role.
