    The occurrence of perfluorinated compounds (PFCs) in human blood is known to be widespread; nevertheless, the sources of exposure to humans, including infants, are not well understood. In this study, breast milk collected from seven countries in Asia was analyzed (n=184) for nine PFCs, including perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA). In addition, five brands of infant formula (n=21) and 11 brands of dairy milk (n=12) collected from retail stores in the United States were analyzed, for comparison with PFC concentrations previously reported for breast milk from the U.S. PFOS was the predominant PFC detected in almost all Asian breast milk samples, followed by perfluorohexanesulfonate (PFHxS) and PFOA. Median concentrations of PFOS in breast milk from Asian countries varied significantly;the lowest concentration of 39.4 pg/mL was found in India, and the highest concentration of 196 pg/mL was found in Japan. The measured concentrations were similarto or less than the concentrations previously reported from Sweden, the United States, and Germany (median, 106-166 pg/mL). PFHxS was found in more than 70% of the samples analyzed from Japan, Malaysia, Philippines, and Vietnam, at mean concentrations ranging from 6.45 (Malaysia) to 15.8 (Philippines) pg/mL PFOA was found frequently only in samples from Japan; the mean concentration for that country was 77.7 pg/mL. None of the PFCs were detected in the infant-formula or dairy-milk samples from the U.S. except a few samples that contained concentrations close to the limit of detection. The estimated average daily intake of PFOS by infants from seven Asian countries, via breastfeeding, was 11.8 +/- 10.6 ng/kg bw/ day; this value is 7-12 times higher than the estimated adult dietary intakes previously reported from Germany, Canada, and Spain. The average daily intake of PFOA by Japanese infants was 9.6 +/- 4.9 ng/kg bw/day, a value 3-10 times greater than the estimated adult dietary intakes reported from Germany and Canada. The highest estimated daily intakes of PFOS and PFOA by infants from seven Asian countries studied were 1-2 orders of magnitude below the tolerable daily intake values recommended by the U.K. Food Standards Agency.

    OBJECTIVES: Guidance and evidence supporting routine use of partially hydrolyzed formula (pHF) versus intact cows' milk protein (CMP) formula are limited in non-exclusively breastfed infants. The aim of this review was to better clarify issues of routine use of pHF in non-exclusively breastfed infants who are not at risk for allergic disease by using a systematic review and Delphi Panel consensus.

    METHODS: A systematic review and Delphi consensus panel (consisting of eight8 international pediatric allergists and gastroenterologists) was conducted to evaluate evidence supporting growth, tolerability, and effectiveness of pHF in non-exclusively breastfed infants.

    RESULTS: None of the studies reviewed identified potential harm of pHF use compared with CMP in non-exclusively breastfed infants. There was an expert consensus that pHF use is likely as safe as intact CMP formula, given studies suggesting these have comparable nutritional parameters. No high-quality studies were identified evaluating the use of pHF to prevent allergic disease in non-exclusively breastfed infants who are not at risk for allergic disease (e.g., lacking a parental history of allergy). Limited data suggest that pHF use in non-exclusively breastfed infants may be associated with improved gastric emptying, decreased colic incidence, and other common functional gastrointestinal symptoms compared with CMP. However, because the data are of insufficient quality, the findings from these studies have to be taken with caution. No studies were identified that directly compared the different types of pHF, but there was an expert consensus that growth, allergenicity, tolerability, effectiveness, and clinical role among such pHF products may differ.

    CONCLUSIONS: Limited data exist evaluating routine use of pHFs in non-exclusively breastfed infants, with no contraindications identified in the systematic review. An expert consensus considers pHFs for which data were available to be as safe as CMP formula as growth is normal. The preventive effect on allergy of pHF in infants who are not at risk for allergic disease has been poorly studied. Cost of pHF versus starter formula with intact protein differs from country to country. However, further studies in larger populations are needed to clinically confirm the benefits of routine use of pHF in non-exclusively breastfed infants. These studies should also address potential consumer preference bias.

    The detection of 3- and 2-MCPD ester and glycidyl ester was transformed from selected ion monitoring (SIM) mode to multiple reaction monitoring (MRM) mode by gas chromatography triple quadrupole spectrometry. The derivatization process was adapted from AOCS method Cd 29a-13. The results showed that the coefficient of determination (R2) of all detected compounds obtained from both detection mode was comparable, which falls between 0.997 and 0.999. The limit of detection and quantification (LOD and LOQ) were improved in MRM mode as compared to SIM mode. In MRM mode, the LOD of 3- and 2-MCPD ester was achieved 0.01 mg/kg while the LOQ was 0.05 mg/kg. Besides, LOD and LOQ of glycidyl ester were 0.024 and 0.06 mg/kg respectively. A blank spiked with MCPD esters (0.03, 0.10 and 0.50 mg/kg) and GE (0.06, 0.24 and 1.20 mg/kg) were chosen for repeatability and recovery tests. MRM mode showed better repeatability in area ratio and recovery with relative standard deviation (RSD %) infant formula products showed certain level of MCPD esters and GE, and their detection was more precisely quantitated based on MRM mode. Besides, margarine products showed a higher level of contaminations due to the high fat content in these products. MRM mode detection was proven to provide precise data with low RSD % in different food matrices. MRM mode detection was robust and selective for MCPD esters and GE analyses, it should be applied to determine the concentration of MCPD esters and GE contaminations in food.

    The prevalence of food allergy has increased over the last 20-30 years, including cow milk allergy (CMA) which is one of the most common causes of infant food allergy. International allergy experts met in 2019 to discuss broad topics in allergy prevention and management of CMA including current challenges and future opportunities. The highlights of the meeting combined with recently published developments are presented here. Primary prevention of CMA should start from pre-pregnancy with a focus on a healthy lifestyle and food diversity to ensure adequate transfer of inhibitory IgG- allergen immune complexes across the placenta especially in mothers with a history of allergic diseases and planned c-section delivery. For non-breastfed infants, there is controversy about the preventive role of partially hydrolyzed formulae (pHF) despite some evidence of health economic benefits among those with a family history of allergy. Clinical management of CMA consists of secondary prevention with a focus on the development of early oral tolerance. The use of extensive Hydrolysate Formulae (eHF) is the nutrition of choice for the majority of non-breastfed infants with CMA; potentially with pre-, probiotics and LCPUFA to support early oral tolerance induction. Future opportunities are, among others, pre- and probiotics supplementation for mothers and high-risk infants for the primary prevention of CMA. A controlled prospective study implementing a step-down milk formulae ladder with various degrees of hydrolysate is proposed for food challenges and early development of oral tolerance. This provides a more precise gradation of milk protein exposure than those currently recommended.

    BACKGROUND: Atopic dermatitis (AD) is one of the most common skin conditions among infants. Proteins found in cow's milk formula (CMF) have been found to be attributable to heightened AD risk, particularly in infants with familial AD heredity. Previous studies have suggested that intervention with partially hydrolyzed formula in nonexclusively breastfed infants can have a protective effect against AD development.

    OBJECTIVE: The aim of the present study was to compare the estimates of the economic impact of reducing the AD incidence by feeding a partially hydrolyzed whey-based formula (PHF-W) instead of a standard CMF to high-risk nonexclusively breastfed urban infants for the first 17 weeks of life in the Philippines, Malaysia, and Singapore.

    METHODS: In each country, a mathematical model simulated AD incidence and burden from birth to 6 years of age of using PHF-W versus CMF in the target population using data from the German Infant Nutritional Intervention study. The models integrated literature, current cost and market data, and expert clinician opinion. Modeled outcomes included AD risk reduction, time spent after AD diagnosis, AD symptom-free days, quality-adjusted life years (QALYs), and costs (direct and indirect). Outcomes were discounted at 3% per year. Costs were expressed in USD.

    RESULTS: Feeding high-risk infants PHF-W instead of CMF resulted in an estimated absolute 14% (95% CI 1-24) AD risk reduction, a 0.69-year (95% CI 0.25-1.13) reduction in the time spent after AD diagnosis per child, reductions of 16-38 AD days, and gains in 0.02-0.04 QALYs, depending on the country. The per-child AD-related 6-year cost-saving estimates of feeding high-risk infants with PHF-W versus CMF were USD 739 in Singapore, USD 372 in Malaysia, and USD 237 in the Philippines.
