Short-term outcomes of oropharyngeal administration of colostrum in preterm neonates: a double-blind placebo-controlled randomized trial.

The oropharyngeal administration of colostrum (OAC) in neonates has several benefits. To investigate the short-term outcomes of OAC in preterm neonates. We performed this two-arm, double-blind, placebo-controlled randomized trial at a tertiary neonatal center in Iran in 2021-2023. The intervention and control arms received 0.2 mL of their mother's colostrum or distilled water via oropharyngeal administration every 6 h for 3 days starting from birth until 72 h of age. The main study outcomes were neonatal death, the incidence of necrotizing enterocolitis (NEC), sepsis, retinopathy of prematurity (ROP), length of hospital stay, and period to full enteral feeding. A regression analysis was used to adjust for possible confounders. A total of 126 neonates (mean gestational age, 30.05 weeks) were randomized to the intervention and placebo groups (n=63 each) and had a mean ± SD weight of 1247 ± 193 vs 1156 ± 215 g (P=0.013) and 1- and 5-min Apgar scores of 6.35 vs 5.38 (P=0.003) and 7.84 vs 7.13 (P=0.001), respectively. The mortality rate was 12.7% in the intervention group versus 14.3% in the placebo group (P=0.794). The NEC rate was significantly lower in the intervention versus placebo arm (11.1% vs. 28.6%, respectively; P=0.010), as was the clinically suspected sepsis rate (15.9% vs. 39.7%, respectively; P=0.004). The ROP and bronchopulmonary dysplasia rates did not differ significantly between groups after the adjustment for confounders. The mean length of hospital stay was shorter in the intervention group (26.1 vs. 37.32; P=0.023). Moreover, the mean duration of antibiotic therapy and period to full feeding were significantly shorter in the intervention group. OAC could effectively decrease the incidence of complications in preterm infants and facilitate earlier patient discharge.

Metagenomics reveals the characteristics and potential spread of microbiomes and virulence factor genes in the dairy cattle production system

Virulence factor genes (VFGs) pose a potential threat to ecological security and animal health, and have attracted increasing attention in the livestock industry. As one of the primary livestock types, dairy cattle may be an important source of VFG transmission. However, the distribution, transmission, and evolution of VFGs in the gastrointestinal tract and surrounding environment of dairy cattle remain unclear. In the present study, a total of 263 samples were collected from cows, calves, colostrum, farm wastewater, and soil. Metagenomics was conducted to analyze changes in the microbiome and VFGs characteristics in these ecological niches. The VFGs of the cows showed distinct differences between the rumen and feces, and were influenced by the region. The dominant VFG hosts was regulated by their microbial structure. Colostrum administration of cows increased VFG abundance in their newborn calf feces sharply and Enterobacteriaceae became the primary host. While diet was the primary driving force for the temporal variation in calf VFGs. For samples of the surrounding environment, water and soil had higher VFG concentrations and were more structurally stable. Moreover, extensive interactions between the mobile genetic elements and VFGs and gene mobile analysis map based on metagenomic binning both displayed the potential horizontal transfer ability of VFGs in the cows and environment. Our study revealed the prevalence, diffusion, and regulatory factors of VFGs in dairy cattle production systems, providing novel insights into reducing livestock VFGs and limiting their spread.

The Impact of Oral Maternal Colostrum Administration on the Immune System of Premature Babies

In children under five years of age, premature complications are now the second leading cause of death. Colostrum has important benefits in promoting the maturity of premature infants' organ functions and preventing infections. Preterm infants are recommended to be given colostrum orally and pharyngeally as early as possible after birth to provide immune protective effects for their bodies. However, the sucking and swallowing functions of preterm infants are often not optimal, partly due to comorbidities, which poses a significant challenge. As a result, the immune system of preterm infants is often low. This literature review aimed to evaluate the effect of oropharyngeal colostrum feeding through subgroup analysis based on complications. Descriptive research was conducted in April-June 2024 using the literature review method with PRISMA guidelines for RCTs. Literature sources were obtained from Pubmed (MEDLINE), Science Direct, Google Scholar, and Cochrane with a publication limit of the last ten years (2014-2023). Of the 1,657 results, 13 articles met the criteria. A total of 1,451 preterm infants were included in the 13 RCT studies. Results showed a lower incidence of late-onset sepsis and Necrotizing Enterocolitis (NEC) in the group that received oropharyngeal colostrum. The administration of oropharyngeal colostrum was shown to have a positive impact on the development and defense of the immune system of preterm infants, reduce health problems such as sepsis and NEC, accelerate the recovery of birth weight, and reduce the incidence of mortality.

The Effect of Swaddling and Oropharyngeal Colostrum During Endotracheal Suctioning on Procedural Pain and Comfort in Premature Neonates: A Randomized Controlled Trial.

Endotracheal suctioning (ES) is a painful procedure frequently performed in the neonatal intensive care unit. This procedure negatively affects the comfort level of premature neonates. To determine the effect of 2 nonpharmacologic methods, swaddling and the administration of oropharyngeal colostrum, on the pain and comfort levels of preterm neonates during ES. This randomized controlled experimental study comprised 48 intubated premature neonates (swaddling group n =16; oropharyngeal colostrum group n =16; and control group n =16) at 26 to 37weeks of gestation. The neonates were swaddled with a white soft cotton cloth or administered 0.4 mL of oropharyngeal colostrum 2minutes before ES, according to the group in which they were included. Two observers evaluated the pain levels (Premature Infant Pain Profile-Revize [PIPP-R]) and comfort (Newborn Comfort Behavior Scale [COMFORTneo]) of the infants by observing video recordings of before, during, and after the procedure. A significantly lower mean PIPP-R score was found in the swaddling group during ES compared with the control group ( P =.002). The mean COMFORTneo scores of the swaddling and oropharyngeal colostrum groups during ES ( P <.01, P =.002) and the mean PIPP-R and COMFORTneo scores immediately after ES and 5, 10, and 15minutes later were significantly lower than the control group ( P <.005). Swaddling was effective both during and after the procedure, while oropharyngeal colostrum was effective only after the procedure in reducing ES-related pain in premature neonates. Swaddling and oropharyngeal colostrum were effective in increasing comfort both during and after the procedure.

Assessing the impact of colostrum feeding delay on serum immunoglobulin G and total protein in dairy goat kids

This experiment was motivated by the need to understand the impacts of delaying the first colostrum feeding on the prevalence of failed transfer of passive immunity (FTPI). A cohort of 216 kids was stratified into groups based on the colostrum feeding delay postbirth: 0–4 h, 4–8 h, 8–12 h, and 12–16 h. All kids received a single colostrum meal of 300 mL, and blood samples were collected approximately 36 h after feeding. Serum immunoglobulin G (SIgG) was measured using ELISA, and serum total protein (STP) was assessed using the Bradford method and refractometry (STPb and STPr). Statistical methods like Pearson correlations, Bland-Altman plots, and Lin’s concordance coefficient were employed to assess associations and agreements between SIgG, STPb and STPr. Receiver operator characteristic analysis was employed to determine optimal STPb and STPr thresholds for predicting FTPI (SIgG < 12 g/L). Subsequently, areas under the curve, sensitivity, and specificity were examined to assess the accuracy of these thresholds. Our results showed that for each hour’s delay from birth to colostrum intake (up to 16 h), IgG apparent efficiency of absorption (AEA) decreases at an approximate rate of 2.0% per hour, and SIgG decreases at an approximate rate of 1.0 g/L per hour. However, this decline is not constant over time but intensifies progressively with increased feeding delay. Specifically, reductions in IgG AEA were 1.3, 2.9, and 5.9% per hour, and decreases in SIgG were 0.2, 0.3, and 0.7 g per hour for SIgG across the time intervals of 0–4 to 4–8 h, 4–8 to 8–12 h, and 8–12 to 12–16 h, respectively. Additionally, there was an increase in SIgG of 1.2 g/dL but a decrease in IgG AEA of 1.9% for each gram per kg of BW increase in IgG intake. The correlations between SIgG and STPr and STPb were 0.62, and 0.36, respectively. Optimal STPr and STPb thresholds predicting FTPI were determined to be 4.6 and 6.2 g/dL. The prevalence of FTPI, according to SIgG, STPr, and STPb thresholds were 63, 62, and 45%. Overall, STPr showed higher values for key performance metrics (i.e., sensitivity, likelihood ratio of positive tests, overall accuracy, and Youden’s index), indicating better prediction ability than STPb. Our findings corroborate the critical importance of swift colostrum administration, ideally occurring no later than 12 h postbirth. Moreover, our research validates the effectiveness of Brix refractometry as a practical, on-farm method for assessing FTPI in goat kids.

Association of oropharyngeal colostrum administration with decreased inflammatory indices in premature newborns weighing less than 1500 g.

The administration of colostrum through its absorption at the oropharyngeal level stimulates the mucosa-associated lymphoid tissue, providing a local immunological protection barrier. The study aimed to investigate the association of oropharyngeal colostrum administration with the reduction of inflammatory indices. This was an observational, ambispective, analytical study of newborns < 32 weeks of gestation at risk of sepsis. Oropharyngeal colostrum was administered at 0.2 mL every 4 h for 5 days. Inflammatory indices were analyzed. Statistical analysis included frequencies, percentages, mean and Standard deviation, contingency coefficient, and Kolmogorov-Smirnov test for the distribution curve of the numerical data. There were 50 patients, 33 (66%) female and 17 (34%) male, with a median gestational age of 30-31 weeks (95% confidence interval [CI]). Nineteen patients had sepsis. A lower positivity rate in C-reactive protein was found, with a median of 0.5-0.6 (95% CI) at 5 days of colostrum administration versus 0.5-1.1 (95% CI) as the initial C-reactive protein. Analysis with χ2 yielded a p = 0.13, and the contingency coefficient showed a p = 0.196, indicating an association. Oropharyngeal colostrum administration was associated with a lower C-reactive protein positivity rate and clinical improvement in premature newborns at risk of sepsis.

Support breastfeeding in premature infants in the neonatal intensive care unit

The multiple benefits of human milk in newborns are known, especially in preterm newborns by reducing the rates of neonatal sepsis, necrotizing enterocolitis, retinopathy of prematurity and better results in neurodevelopment. However, rates of exclusive breast milk use remain low. To achieve higher percentages of successful breastfeeding, strategies must be applied from the NICU, such as expressed within the first 6 hours of life, skin-to-skin contact and administration of colostrum in the cheeks, all well, in order to have sufficient volume of breast milk since this is the main barrier they face, not having enough milk. There are very few studies that evaluate when to initiate suctions directly to the maternal breast, using the empty breast as non-nutritive suction could improve the performance of VLBW to the maternal breast.

Short-Term Outcomes of Early Oral Colostrum Administration in VLBW Neonates: An Open-Label Randomized Controlled Trial.

Oropharyngeal colostrum priming (OCP) has been proposed as a potential nutritional option for very low birth weight (VLBW) newborns. This study aimed to determine short-term outcomes of early oral colostrum administration in VLBW neonates. This open-label randomized controlled trial was conducted on VLBW neonates admitted to Mahdieh Hospital, Tehran, Iran, between February and December 2022. According to the protocol, all eligible neonates were randomized evenly to the intervention group, which received oral colostrum (OC), and the control group, which received no OC. Finally, short-term outcomes of early OC administration were compared between groups using the independent-samples t test, chi-square, and Fisher exact tests. Of 80 randomized neonates, 37 and 39 from the intervention and control groups entered the final analysis, respectively. Neonates in the intervention and control groups did not significantly differ in terms of peripherally inserted central catheter (PICC) infection (P = 0.728), sepsis (P = 0.904), necrotizing enterocolitis (NEC) (P > 0.999), intraventricular hemorrhage (IVH) (P = 0.141), retinopathy of prematurity (ROP) (P = 0.923), and bronchopulmonary dysplasia (BPD) (P = 0.633). Furthermore, there was no significant difference between groups considering the time to reach 120 cc/kg feeds (P = 0.557), time to reach birth weight (P = 0.157), length of hospitalization (P = 0.532), and mortality rate (P = 0.628). The results of our study revealed that despite safety, early OC administration did not improve any of the short-term outcomes in VLBW neonates.

Effect of Dietary Supplementation of Chestnut and Quebracho Tannin Supplementation on Neonatal Diarrhoea in Preweaning Calves.

Neonatal calf diarrhoea (NCD) poses a significant health challenge in cattle herds, resulting in considerable economic losses and antimicrobial use. In response to the escalating threat of antimicrobial resistance, viable alternatives are imperative, aligning with European policies. This study evaluated the in-milk supplementation of the chestnut and quebracho tannin extract in preweaning calves on performance, diarrhoea occurrence, Cryptosporidium spp. shedding, protein digestibility, and intestinal health. Twenty newborn calves were divided, after colostrum administration, into two experimental groups for 30 days as follows: the control (CTRL) was fed with whole milk and solid feed, and tannins (TAN) were fed whole milk supplemented with 6/g day of tannin extract and solid feed. Faecal samples were collected on days 0, 3, 7, 14, and 30 for the evaluation of Cryptosporidium oocyst shedding and protein digestibility. Faecal consistency was evaluated during the sampling using the faecal score scale (0-3 scale, considering diarrhoea > 1). The results showed a significant reduction in diarrhoea frequency in the TAN compared to the CTRL group (p < 0.05) over 30 days of the trial. The prevalence of Cryptosporidium spp. was generally low (12%), considering all analysed samples. Protein digestibility revealed comparable values for the TAN and CTRL groups, suggesting that tannins did not negatively affect milk protein availability. In conclusion, the in-milk supplementation of 6/g day of the chestnut and quebracho tannin extract could be considered a valuable functional feed additive to decrease NCD occurrence, thus supporting animal health and decreasing antibiotic use in livestock.

DUKUNGAN KELUARGA TERHADAP PEMBERIAN KOLOSTRUM PADA IBU POSTPARTUM SECTIO CAESAREA

Background: The number of post sectio cesarea patients at PKU Aisyiyah Jepara Hospital in June 2021 – April 2022 was 458 patients, data on infants who were breastfed colustrum in postpartum mothers with cesarean sectio were 102 babies. It can be said that the coverage of colustrum breastfeeding at PKU Aisyiyah Jepara Hospital tends to be less than babies who are not given colustrum breastfeeding. While mothers who did not give colustrum breast milk as much as 22.2%. Objective: Knowing the relationship between family support for colostrum administration to postpartum SC mothers at PKU Aisyiyah Jepara Hospital. Method: A type of correlational analytic research with a cross sectional time approach. Large sample of 41 respondents with total sampling technique. The instrument used questionnaire. Analysis of statistical test data of Spearman Rho. Research Results: The majority of respondents' family support was sufficient, namely as many as 27 people (65.9%) and mothers gave colostrum as many as 32 people (78%). Conclusion: There is a relationship between family support for colostrum administration to postpartum SC mothers at PKU Aisyiyah Jepara Hospital with p value 0.001 α 0.05 and r value = 0.487.

The Feeding Habbits On Incidence Of Stunting

Stunting emerges as a consequential nutritional challenge among toddlers, resulting from prolonged exposure to malnutrition. Rooted in familial caregiving practices, particularly feeding habits, this study delves into the nexus between feeding behaviors and the prevalence of stunting among impoverished families in Palembang. Employing a quantitative approach through a Cross Sectional Study, the research encompasses 110 mothers with children aged 24-59 months from economically disadvantaged backgrounds in Palembang. The findings underscore a noteworthy correlation between feeding habits and the incidence of toddler stunting, yielding a significant p-value of 0.000 and an Odds Ratio of 14.389. Noteworthy feeding practices influencing stunting include the administration of colostrum at birth (p-value = 0.020), diversified feeding (p-value = 0.000), nutritionally balanced meals (p-value = 0.003), maternal food preparation (p-value = 0.005), consistent snack provision (p-value = 0.002), age-appropriate portion adjustments (p-value = 0.042), offering food choices during boredom (p-value = 0.001), active feeding assistance (p-value = 0.001), maternal efforts to encourage eating (p-value = 0.000), and fostering an interest in eating (p-value = 0.007). Comparatively, non-stunted toddlers exhibit superior feeding habits when juxtaposed with their stunted counterparts within similar economic circumstances. This research illuminates the pivotal role of feeding practices in mitigating or exacerbating toddler stunting, thereby advocating for targeted interventions to enhance nutritional well-being in vulnerable populations.

Oropharyngeal administration of colostrum targeting gut microbiota and metabolites in very preterm infants: protocol for a multicenter randomized controlled trial

BackgroundOropharyngeal administration of colostrum (OAC) has an immune-stimulating effect on oropharyngeal-associated lymphoid tissue, and can promote the maturation of the gastrointestinal tract. However, how OAC promotes intestinal maturation in preterm infants by altering gut microbiota remains unclear. We aim to assess changes in gut microbiota and metabolites after OAC in very preterm infants.MethodsA multicenter, double-blind, randomized controlled trial will be conducted in three large neonatal intensive care units in Shenzhen, China, with preterm infants with gestational age less than 32 weeks at birth and birth weight less than 1500 g. It is estimated that 320 preterm infants will be enrolled in this study within one year. The intervention group will receive oropharyngeal administration of 0.2 ml colostrum every 3 h, starting between the first 48 to 72 h and continued for 5 consecutive days. Following a similar administration scheme, the control group will receive oropharyngeal administration of sterile water. Stool samples will be collected at the first defecation, as well as on the 7th, 14th, 21st and 28th days after birth for analysis of effect of OAC on gut microbiota and metabolites through 16sRNA gene sequencing and liquid chromatography-mass spectrometry.DiscussionThis proposal advocates for the promotion of OAC as a safe and relatively beneficial protocol in neonatal intensive care units, which may contribute to the establishment of a dominant intestinal flora. Findings of this study may help improve the health outcomes of preterm infants by establishment of targeted gut microbiota in future studies.Trial registrationNCT05481866 (registered July 30, 2022 on ClinicalTrials.gov).

The effect of maternal supply of rumen-protected protein to Holstein Friesian cows during the dry period on the transfer of passive immunity and colostral microbial composition

The objective of this study was to analyze if maternal supply of rumen-protected protein during the dry period can affect the IgG concentration and microbial composition of colostrum and the IgG absorption and fecal microbial composition in the calf. Seventy-four multiparous Holstein Friesian (HF) dairy cows were stratified per parity and randomly assigned to one of 2 different dry period diets, a diet with a low crude protein (CP) level (LP) and a diet with a high CP level (HP) by addition of rumen-undegraded protein (RUP; formaldehyde-treated soybean meal, Mervobest, Nuscience, Drongen, Belgium). Colostrum was collected within 1 h after calving and IgG concentration was quantified by radial immunodiffusion analysis. Forty-nine calves (23 female and 26 male) were enrolled in the trial with a 2 × 2 factorial design, with prenatal and postnatal treatment as the 2 independent variables. This led to 4 experimental groups: LPLP, LPHP, HPLP, and HPHP, in which the first 2 letters refer to the prenatal treatment (diet of the dam) and the last 2 refer to the postnatal treatment (diet of the colostrum-producing cow). Calves received 3× 2 L of colostrum within 2, 6, and 24 h after birth. Meconium and feces were collected solely from female calves (n = 18) by digital palpation of the rectum, immediately after birth and before colostrum administration and at d 3 of age. Microbial DNA was extracted from meconium (n = 9), feces (n = 15), and colostrum (n = 49). Amplicon sequencing of the bacterial V3-V4 region of the 16S rRNA gene was performed for characterization of the bacterial communities. Colostrum IgG concentration was higher in cows that were supplemented with RUP, especially in cows entering their second lactation (LSM ± SEM 61.3 ± 2.3 vs. 55.2 ± 2.8 g of IgG/L). Calves born out of LP cows that received colostrum from HP cows (LPHP) had a lower serum IgG level compared with HPHP and LPLP calves (LSM ± SEM 14.2 ± 1.3 vs. 18.8 ± 1.2 and 20.9 ± 1.3 g of IgG/L in HPHP and LPLP, respectively). The most abundant phyla in colostrum were Proteobacteria (48.2%), Firmicutes (24.8%), Bacteroidetes (9.5%), and Actinobacteria (5.0%). The most abundant phyla in calf meconium and feces were Firmicutes (42.5 and 47.5%), Proteobacteria (21.7% and 33.7%), Bacteroidetes (16.8% and 15.7%), and Actinobacteria (2.9% and 3.1%). There was no difference in the overall microbial communities between colostrum from HP and LP cows. However, 2 genera (both members of the family Lachnospiraceae) were more abundant in colostrum from HP cows compared with LP cows. The microbial composition of meconium, feces and colostrum differed from each other. Fecal samples were more similar to each other and are characterized by a lower intersample diversity compared with colostrum and meconium samples. To conclude, increasing the CP level by addition of RUP in the dry period diet affected the colostrum IgG concentration and the transfer of passive immunity, but did not change the overall microbial composition of colostrum nor of meconium and feces in the calf.

Clinical adaptation and the state of innate and humoral im- munity of premature infants with extremely low body weight who received oropharyngeal administration of colostrum

Breast milk is the optimal food for premature infants. However, the serious condition of premature newborns requires a complex of primary resuscitation care in the maternity unit, which makes it impossible to carry out early attachment to the breast and start breastfeeding. Currently, the neonatal community is actively discussing the immune effects of an alternative method of oropharyngeal administration of colostrum on the child’s adaptation to extrauterine existence. Purpose. To assess the clinical outcomes, the state of the monocytic immunity, the production of sIgA in coprofiltrates in premature infants with extremely low body weight who received colostrum in the first hours of life. Material and methods. 39 premature infants with extremely low body weight who received oropharyngeal administration of colostrum were examined. The expression of CD14+CD282+, CD14+CD284+, CD14+HLA-DR, CD14+CD64+, CD14+CD11b+, CD14+CD11c+ monocytes and the phagocytic ability of mononuclear cells in blood serum were determined by laser flow cytometry. The secretory IgA concentration was assessed in coprofiltrates. Results. In premature infants who did not receive oropharyngeal colostrum, there was an increase in leukocyte phagocytosis, the level of monocyte expression, which was due to an increased infectious morbidity. Mucosal immunity of children who received colostrum was characterized by an increased concentration of secretory IgA. Conclusion. It was found that children who received oropharyngeal administration of colostrum have a faster correction of transient hypoglycemia after birth, a shorter duration of parenteral nutrition, greater body weight at the time of discharge, and a decrease in the incidence of infectious pathology.

Investigation of bovine serum albumin‐specific IgE expression in horses

SummaryBackgroundNeonatal foals are born essentially agammaglobulinaemic and therefore must ingest colostrum or receive immunoglobulins to maintain health. Failure of passive transfer treatment involves administration of equine colostrum, plasma or commercial powdered colostrum (CPC). Anecdotal reports suggest the risk of anaphylaxis associated with plasma transfusion in neonates receiving CPC prior to gut closure. Bovine serum albumin (BSA) in CPC may serve as a target for BSA‐specific immunoglobulin E (IgE) in donor equine plasma.ObjectivesTo determine the presence of BSA‐specific IgE in samples of commercial equine plasma, samples were collected following routine vaccination in healthy horses and horses experiencing adverse vaccine reactions.Study designProspective observational.MethodsSerum was collected from: 65 healthy horses at days 0, 14, 28, 90, 180, 270 and 365 post‐vaccination; 26 horses after vaccine reaction at days 1, 180 or 270 post‐vaccination; 4 horses not vaccinated; and 9 horses from a commercial plasma donor herd. BSA‐specific IgE was determined using enzyme‐linked immunosorbent assay.ResultsBovine serum albumin‐specific IgE was not detected in non‐vaccinated horses and was identified in all vaccinated horses. Younger horses demonstrated a trend for higher fold changes in post‐vaccination BSA‐specific IgE expression compared to older horses. No significant difference in BSA‐specific IgE levels between commercial plasma donors and healthy horses was identified. No significant difference in post‐vaccination BSA‐specific IgE levels between the reactor and healthy horses at days 180 and 270 post‐vaccination were identified.Main limitationsSmall number of reactor horses at day 180 and 270 post‐vaccination with most samples being collected 24 h. There were no healthy horse samples for 24 h post‐vaccination; therefore, it was not possible to compare the groups at this timepoint.ConclusionsHorses may express BSA‐specific IgE following vaccination. There may be a risk of hypersensitivity type reaction when veterinarians administer commercial plasma to neonatal foals consuming CPC prior to gut closure.

Colostrum and Preterm Babies: A Systematic Review.

Colostrum from mothers is rich in immunomodulating bio-factors such as immunoglobulins (IgA), lactoferrin, and oligosaccharides and supports gut microbial and inflammatory processes. The support in these processes may provide some relief for infants who are born pre-term. Pre-term infants are more likely to develop necrotizing enterocolitis (NEC), late-onset sepsis (LOS), and ventilator-acquired/associated pneumonia (VAP). Due to the components of colostrum, there may be incentives towards early administration for preterm infants. An extensive literature review was done using ProQuest, ScienceDirect, and PubMed. Only meta-analyses and experimental studies were used. The search included the keywords 'colostrum and preterm' and 'colostrum and necrotizing enterocolitis'. The initial search generated 13,543 articles and was narrowed to 25 articles through comprehensive inclusion and exclusion criteria. There were significantly higher levels of Lactobacillus and Bifidobacterium in pre-term infants given colostrum and a decrease in Moraxellaceae and Staphylococcaceae. Salivary secretory IgA increased following oral colostrum administration in pre-term infants along with downregulation of interleukin (IL)-1b and IL-8. It was also observed that tumor necrosis factor (TNF)-a, and interferon-gamma (IFN-g) were significantly higher in the control group. There was no significant difference in the incidence of LOS, NEC, or VAP between pre-term infants receiving colostrum and those who did not. Secondary outcomes such as time to full enteral feeding were improved in pre-term infants receiving oral colostrum in addition to reduced hospital stays. Lastly, there was no difference in mortality between pre-term infants that received colostrum compared to those who did not.

Learning for Pregnant Women About Giving Colostrum to Newborns at the Cimone Health Center, Tangerang City

The purpose of this study was to determine the factors associated with the administration of colostrum to newborns at the Cimone Health Center, Tangerang City, Banten Province. This study uses a type of observational analytic research. The research method used is cross sectional. The population used in this study were women giving birth normally at the Cimone Health Center, totaling 56 people in October 2020. This research used an accidental sampling technique. The results of a statistical study using chi-square showed that the variables of knowledge and family support were related to the administration of colostrum to newborns with a p-value of (0.001 &lt; α (0.05) and (0.004 &lt; α (0.05), so it can be concluded that mothers with good knowledge have a greater chance of giving colostrum than mothers with less knowledge, and mothers with family support have a greater chance of giving colostrum than mothers with unsupportive family support

Administration colostrum in preventing mortality and morbidity in preterm infants

Background: Oropharyngeal administration of colostrum has found to play a role in preventing the Necrotizing Enterocolitis (NEC), thus reducing mortality and morbidity in preterm infants. We aimed to determine whether early oropharyngeal administration of mother’s own colostrum can reduce the rates of NEC and/or mortality in preterm infants. Methods: We conducted a randomized, placebo controlled, intervention study in Department of Neonatology, Bangabandhu Sheikh Mujib Medical University, Dhaka from 2019 to 2021. Total 92 infants were enrolled, 52 were randomized to oropharyngeal administration of colostrum group and 40 to placebo group. Oropharyngeal administration of colostrum group received maternal colostrum (0.2 ml), after 24 hours of postnatal life and were given every 3 hour for the next 3 days. Serum IgA was measured at 24 hrs and 7th day of postnatal age. Clinical data during hospitalization were collected. SPSS version 21 was used for statistical analysis. Results: Baseline characteristics were comparable and almost similar between the two groups. There was significant reduction in the incidence of NEC stage 2, 16 (30.7%) vs. 26, (65%); p = 0.001). There was significant reduction of age of achieving full enteral feeding (12.1±4.5 vs 19.5±7.5; p = 0.001), disseminated intravascular coagulation (DIC) 12 (23%) vs. 22 (55%); p=0.002, use of mechanical ventilators, 11 (21.1%) vs. 22 (55%); p = 0.001 and number of inotropes (1.2±0.3 vs. 1.61±0.4975; p = 0.002), duration of inotropes (19.7±14.2 vs. 36.5±17.5; p=0.002) in OAC group. However, there was no significant difference in probable sepsis, culture proven sepsis, survival rate and serum IgA level at 1st and 7th day in OAC group, compared to placebo. Conclusions: There was a positive effect in decreasing the incidence of NEC, but no significant effect was observed on survival rate. This intervention facilitates faster achievement of full enteral feeding, reducing the risk of DIC in preterm infants.

Nutritional Factors Affecting Stunting Among Toddlers

Background: Stunting is one of Indonesia's most serious nutritional issues. Malang Regency has a 12 percent prevalence of stunting in 2020, with Gondanglegi sub-district having 942 stunted children. One effort to improve toddler nutrition is the administration of colostrum, exclusive breastfeeding, and complementary feeding. Inappropriate colostrum administration, exclusive breastfeeding, and complementary feeding can all increase the risk of stunting in toddlers. Aims: this study aimed to identify the factors that cause stunting in toddlers based on their behavior in meeting their nutritional needs in Gondanglegi sub-district, Malang Regency. Methods: A total of 136 children aged 6 to 59 months were divided into two equal groups for the case-control study. The research was carried out at Ketawang and Gondanglegi Primary Health Centers in Indonesia's Gondanglegi sub-district. Weight and height measurements, a questionnaire-based interview, and a 24-hour food recall were all collected. With a significance level of 0,05, Chi-square was used to determine the factors influencing stunting. To perform multivariate analysis, logistic regression was used. Results: Colostrum administration, exclusive breastfeeding, and complementary feeding were all linked to stunting in bivariate analysis (p&lt; 0.05). According to a multivariate analysis, exclusive breastfeeding (OR=4,8) is strongly associated with stunting among toddlers in Gondanglegi sub-district, Malang Regency, Indonesia. Conclusion: Breast milk contains many nutrients and antibodies that can protect babies from infection by reducing the duration and severity of illness that can lead to chronic malnutrition and stunting.

A meta-analysis of the effects of colostrum heat treatment on colostral viscosity, immunoglobulin G concentration, and the transfer of passive immunity in newborn dairy calves

Newborn ruminants depend on colostrum intake immediately after birth to obtain immunoglobulins for effective transfer of passive immunity (TPI). As colostrum may also be a vehicle of infectious agents, heat treatment of raw colostrum is a practice aimed at eliminating or reducing its pathogen load. Despite the usefulness of heat treatment in preventing the transmission of infectious colostrum-borne diseases, heat treatment of colostrum may have some side effects. A systematic review and meta-analysis were conducted to summarize the effects of colostrum heat treatment on colostral viscosity and IgG concentration, and serum IgG concentration as a proxy for TPI in newborn calves fed raw versus heat-treated colostrum. Moderators were studied to identify sources of heterogeneity. Literature databases were searched for peer-reviewed articles published between 1946 and 2022. A Master of Science thesis was also included. Five, 21, and 19 original publications were quantitatively evaluated in 3 separate meta-analyses, based on predefined selection criteria. Two-level and 3-level random-effects meta-analysis revealed a significant overall effect of heat treatment on colostral viscosity and IgG concentration, and serum IgG concentration in newborns. Heat-treated colostrum had significantly higher viscosity (21.0 cP, 95% CI: 3.8 to 38.2) and lower IgG concentration (-7.4 g/L, 95% CI: -11.1 to -3.7) compared with raw colostrum. Overall, newborn calves fed heat-treated colostrum had higher serum IgG concentrations (2.8 g/L, 95% CI: 1.4 to 4.0) 24-48 h after birth than those fed with raw colostrum. Particularly, this positive effect on the serum IgG concentrations was seen when colostrum was heat-treated at ≤60°C (2.9 g/L, 95% CI: 0.9 to 4.2) and when the standard low-temperature low-time (LTLT) method was used for heat treatment (2.6 g/L, 95% CI: 0.1 to 5.1). Colostrum treated at >60-63.5°C tended to have higher viscosity (275.6 cP, 95% CI: -37.9 to 589.3) and had lower IgG concentration (-21.7 g/L, 95% CI: -27.3 to -16.1). Calves fed colostrum treated at this temperature range had significantly lower serum IgG (-4.2 g/L, 95% CI: -7.9 to -0.4) compared with those fed raw colostrum. Heat treatment of colostrum at 72-76°C was not associated with a significant increase in colostral viscosity (6.3 cP, 95% CI: -324.3 to 336.9) nor a reduction in IgG colostral concentration (-13.1 g/L, 95% CI: -26.5 to 0.2), but calves fed colostrum treated at this temperature range had a significant reduction in serum IgG (-11.3 g/L, 95% CI: -17.1 to -5.4). Feeding newborn calves with colostrum heat-treated at ≤60°C by the standard LTLT method, particularly within 2 h after birth, resulted in increased serum IgG concentration at 24-48 h of age. Importantly, delaying feeding of heat-treated colostrum to newborns beyond 2 h of age resulted in no significant difference in IgG serum levels compared with feeding raw colostrum, highlighting the importance of early administration of heat-treated colostrum to favor TPI. On-farm colostrum heat treating should achieve an equilibrium between pathogen elimination and the preservation of colostral immunoglobulins while minimizing undesired increases in viscosity. The beneficial effects of colostrum heat treatment on TPI can be negligible if colostrum feeding is not performed within 2 h after birth.
