Iodine status and associations with feeding practices and psychomotor milestone development in six‐month‐old South African infants

Iodine is important for normal growth and psychomotor development. While infants below 6 months of age receive iodine from breast milk or fortified infant formula, the introduction of complementary foods poses a serious risk for deteriorating iodine status. This cross‐sectional analysis assessed the iodine status of six‐month‐old South African infants and explored its associations with feeding practices and psychomotor milestone development. Iodine concentrations were measured in infant (n = 386) and maternal (n = 371) urine (urinary iodine concentration [UIC]), and in breast milk (n = 257 [breast milk iodine concentrations]). Feeding practices and psychomotor milestone development were assessed in all infants. The median (25th–75th percentile) UIC in infants was 345 (213–596) μg/L and was significantly lower in stunted (302 [195–504] μg/L) than non‐stunted (366 [225–641] μg/L) infants. Only 6.7% of infants were deficient. Maternal UIC (128 [81–216] μg/L; r_s = 0.218, p < 0.001) and breast milk iodine concentrations (170 [110–270] μg/kg; r_s = 0.447, p < 0.0001) were associated with infant UIC. Most infants (72%) were breastfed and tended to have higher UIC than non‐breastfed infants (p = 0.074). Almost all infants (95%) consumed semi‐solid or solid foods, with commercial infant cereals (60%) and jarred infant foods (20%) being the most common solid foods first introduced. Infants who reported to consume commercial infant cereals ≥4 days weekly had significantly higher UIC (372 [225–637] μg/L) than those reported to consume commercial infant cereals seldom or never (308 [200–517] μg/L; p = 0.023). No associations between infant UIC and psychomotor developmental scores were observed. Our results suggest that iodine intake in the studied six‐month‐old infants was adequate. Iodine in breast milk and commercial infant cereals potentially contributed to this adequate intake.     

Energy intake from unhealthy snack food/beverage among 12‐23‐month‐old children in urban Nepal

Unhealthy snack food and beverage (USFB) consumption among young children has been noted in many low‐income and middle‐income countries (LMIC), however, there is a lack of information on the contribution of these foods to children's diets in these contexts. This study describes the nutrient profiles and costs of snacks consumed by young children in Kathmandu Valley, Nepal, and assesses the proportion of total energy intake from nonbreastmilk foods (%TEI‐NBF) contributed by USFB and factors associated with high USFB consumption. A cross‐sectional survey was conducted among 745 randomly sampled primary caregivers of children aged 12–23 months. Of 239 unique snack foods and beverages consumed, 180 (75.3%) were classified as unhealthy based on nutrient profiling, with 158 of these being commercially branded. Median cost/100 kcal of USFB was lower as compared with healthy snacks. Ninety‐one percent of children had consumed a USFB in the previous 24 hr, with these foods contributing a mean %TEI‐NBF of 24.5 ± 0.7 among all children. Biscuits (10.8%), candy/chocolate (3.5%), and savoury snacks (3.4%) provided the largest %TEI‐NBF. Children who were older, female, or from the poorest households had significantly higher odds of high USFB consumption, whereas children whose caregivers were of upper caste/ethnicity or had achieved tertiary education had lower odds of consumption than other children. To reduce USFB consumption, interventions should seek to further understand social/cultural drivers of feeding practices, target disadvantaged populations, and ensure caregivers are fully aware of the nutritional quality of food products they choose for their children.     

Serum 25 hydroxyvitamin D status in 6‐month‐old infants in Guangzhou,China: A paired longitudinal follow up study

To assess the vitamin D status in healthy 6‐month‐old infants, as well as vitamin D supplementation and feeding patterns in Guangzhou, China, serum 25‐hydroxyvitamin D (25OHD) concentrations of 202 infants were measured at birth (cord blood) and at 6 months of age in Guangzhou, China. Questionnaires acquiring demographic characteristics, maternal and infantile vitamin D supplementation during pregnancy and first 6 months after birth, and feeding patterns during the first 6 months were completed by participating mothers. Physical examinations and blood sampling were carried out among infants at 6 months of age. The majority of infants (93.6%) were supplemented with vitamin D during the first 6 months of life on a voluntary basis. The M ± SD of cord serum 25OHD concentration was 46.2 ± 16.4 nmol/L, whereas the M ± SD of 25OHD concentration at 6 months was 82.9 ± 24.9 nmol/L. Serum 25OHD concentrations <30 nmol/L were seen in 34 (16.8%) infants at birth but only one (0.5%) at 6 months. Only 11 (5.4%) infants had concentrations >75 nmol/L at birth, whereas the majority of infants (n = 131, 64.9%) had concentrations >75 nmol/L at 6 months. The main predictors of 25OHD levels at 6 months included season, vitamin D supplementation, parental education level, and feeding patterns. To conclude, serum 25OHD concentrations were low at birth in a southern Chinese population, and infantile supplementation is an effective way to improve 25OHD status. Exclusively breastfed infants might need greater vitamin D supplementation, and individualized vitamin D supplementation plans might be needed.     

Factors associated with breast milk intake among 9–10‐month‐old Malawian infants

Exclusive breastfeeding is recommended during the first 6 months of life; thereafter, continued breastfeeding along with nutritious complementary foods is recommended. Continued breastfeeding contributes a substantial proportion of nutrient needs and promotes healthy growth and development, but the quantity of breast milk consumed may be highly variable and little is known about the factors associated with breast milk intake after 6 months of age. The present study was conducted to assess factors associated with breast milk intake of Malawian infants at 9–10 months of age. Breast milk intake was measured using the dose‐to‐mother deuterium oxide dilution method in a subsample of 358 Malawian infants who were participating in a randomized controlled trial of lipid‐based nutrient supplements. Regression analysis was used to assess associations between breast milk intake and several maternal and infant variables. Mean (standard deviation) breast milk intake was 752 (244) g day^–1. In multiple regression, breast milk intake was positively associated with infant weight (+62 g per kg body weight, P < 0.01) and maternal height (P < 0.01) and negatively associated with maternal education and age (P < 0.01). There was a non‐significant (P = 0.063) inverse association between energy from non‐breast milk sources and breast milk intake. In this rural Malawian population, infant weight is the main predictor of breast milk intake, even after the first 6 months of life.     

Caregiver–infant's feeding behaviours are associated with energy intake of 9‐11 month‐old infants in rural Ethiopia

Inappropriate complementary feeding, both in quantity and quality, is a major determinant of undernutrition. However, little is known about how infant–caregiver's feeding behaviours affect infants' energy intake. Therefore, the objective of this study was to characterize infant–caregiver feeding behaviours and investigate their association with infants' energy intake. The study involved 106 mother–child pairs recruited from seven randomly selected kebeles of Mecha district, West Gojam, Ethiopia. The feeding styles were assessed through observations of 1‐day, in‐home, feeding episodes that were videotaped and coded into self‐feeding, responsive, active, distracting, and social feeding behaviours. Infants' haemoglobin and anthropometric measurements were taken. The association between feeding behaviour scores and energy intake per meal was investigated. The mean food intake of the infants was very low (11.4 ± 7.0 g/kg body weight per meal) compared to the minimum theoretical gastric capacity (30 g/kg body weight per meal). Infants' haemoglobin concentration was negatively associated with energy intake (ρ = 0.178, p = .03). Infants' responsive and active positive feeding styles were positively associated with energy intakes (ρ = 0.258 and 0.432, p = .004 and p < .001, respectively) as well as caregivers' responsive positive feeding styles (ρ = 0.237, p = .007). Both haemoglobin concentrations and feeding styles were associated with infant's energy intake. Anaemia prevention and control measures should be reinforced. Current nutrition education programmes should give emphasis on ways to effectively incorporate culturally adapted responsive feeding messages in this and similar settings.     

Collagenous sprue in a 3‐month‐old infant

Collagenous sprue (CS) is a severe malabsorption disorder, the etiology of which has not been well defined. Herein, we report the case of a 3‐month‐old infant with CS who responded to steroid and immunomodulator treatment and presented a thick subepithelial collagen band. A 3‐month‐old Japanese girl presented with severe watery diarrhea that lasted for 2 weeks. She was admitted to the referring hospital, but symptomatic improvement was not achieved with fasting and rehydration. Gastroduodenal endoscopy showed an edematous duodenal mucosal surface. Duodenal biopsy indicated severe villous atrophy with infiltration of mostly CD8‐positive T cells; and deposition of subepithelial collagen was confirmed. The subepithelial collagen deposits, however, had disappeared after treatment. Historically, child‐onset CS is extremely rare and this case is likely to be the youngest case of infantile CS. The present case suggests that CS should be considered as a differential diagnosis for intractable diarrhea, even in infants.     

Prechewing infant food,consumption of sweets and dairy and not breastfeeding are associated with increased diarrhoea risk of 10‐month‐old infants in the United States

Prechewing of food by caregivers is a common infant feeding practice both globally and in the United States, where the highest rates of the practice are found among African‐Americans and Alaska Natives. The objective of this study was to determine if prechewing of infant food is associated with increased diarrhoea prevalence of 10‐month‐old infants in the United States. The study used cross‐sectional data from the Infant Feeding Practices Study II to test for associations between prechewing and 2‐week‐period prevalence of infant diarrhoea. At 10 months of age, infants who received prechewed food (n = 203) had a diarrhoea prevalence of 16.1%, compared with 10.9% of children who did not receive prechewed food (n = 1567) [relative risk (RR) = 1.48, 95% confidence interval (CI) 1.03–2.11]. After adjusting for covariates, including breastfeeding and consuming sweets and dairy, prechewing was associated with a 58% higher risk (RR = 1.58, 95% CI 1.10–2.26) of 2‐week diarrhoea prevalence. Consumption of sweets (RR = 1.35, 95% CI 1.03–1.78) and dairy (RR = 1.41, 95% CI 1.03–1.93) was also associated with increased diarrhoea risk. Continued breastfeeding at 10 months of age was associated with a reduced risk of diarrhoea (RR = 0.68, 95% CI 0.50–0.91). Prechewing of infant food is associated with increased diarrhoea among 10‐month‐old infants. The high RR found in this study suggests that prechewing may be an important factor in public health efforts to reduce the burden of diarrhoeal disease. However, further research is needed to establish that prechewing causes increased diarrhoea risk and to explore potential benefits of prechewing.     

Associations of plasma total phospholipid fatty acid patterns with feeding practices,growth, and psychomotor development in 6‐month‐old South African infants

The objective of this study was to assess plasma fatty acid (FA) patterns of 6‐month‐old South African infants and to determine their association with feeding practices, growth, and psychomotor development. Plasma total phospholipid FA composition (% of total FAs) of 6‐month‐old infants (n = 353) from a peri‐urban township was analysed, and principal component and factor analysis were performed to identify plasma FA patterns. Feeding practices, anthropometric measurements, and psychomotor development scores were determined. Four major plasma phospholipid FA patterns were identified: A plant‐based C18 FA, a high n‐6 long‐chain polyunsaturated fatty acids (LCPUFA), a C16:1 and long‐chain saturated fatty acid (SFA), and a high n‐3 and low n‐6 LCPUFA pattern. Formula feeding was associated with higher, whereas breastfeeding was associated with lower scores for the plant‐based C18 FA and C16:1 and long‐chain SFA patterns. On the other hand, breastfeeding, the consumption of cow's milk, and the consumption of semisolid foods were associated with higher scores, whereas formula feeding was associated with lower scores for the high n‐6 LCPUFA pattern. Breastfeeding and the consumption of semisolids were also associated with higher high n‐3 and low n‐6 LCPUFA pattern scores. The C16:1 and long‐chain SFA and high n‐3 and low n‐6 LCPUFA patterns were positively associated with psychomotor development scores. In 6‐month‐old South African infants, we identified distinct plasma FA patterns that presumably represent the FA quality of their diet and that are associated with psychomotor development. Our results suggest that breast milk is an important source of n‐6 LCPUFAs and formula‐fed infants may be at risk of inadequate LCPUFA intake.     

Breastfeeding modifies the impact of diarrhoeal disease on relative weight: a longitudinal analysis of 2–12 month‐old Filipino infants

Undernutrition and diarrhoeal disease are major causes of infant mortality. We investigated the combined roles of breastfeeding and diarrhoea on infant size in 2940 infants from the Cebu Longitudinal Health and Nutrition Survey. The study aimed to assess whether breastfeeding status modified the deficits associated with diarrhoeal disease. The primary exposures were combinations of current breastfeeding status (yes/no), the presence of diarrhoeal disease in previous week (yes/no) and a categorical survey variable (six surveys taken at bimonthly intervals when infants were 2–12 months of age). Relative weight (weight‐for‐length z‐scores), calculated using the WHO growth standards, was estimated using sex‐stratified, fixed‐effects longitudinal models that also adjusted for energy from complementary foods. Post‐estimation Wald tests were conducted to identify subgroup differences in relative weight. Diarrhoea was associated with reduced relative weight in both breastfed and non‐breastfed infants of 6–12 months. Diarrhoea‐related deficits in relative weight were significantly exacerbated in non‐breastfed girls of 6 and 8 months. Importantly, in infants <6 months, being breastfed and having diarrhoea was still associated with greater relative weight compared with being non‐breastfed and diarrhoea‐free. Breastfeeding emerged as a strong contributor to relative weight in younger infants (<6 months) while diarrhoeal disease strongly contributed to deficits in relative weight in older infants (6–12 months). These findings underscore the importance of breastfeeding for promoting infant nutritional status in infants with or without diarrhoea from birth to 12 months.     

Correlation between unconjugated bilirubin and total cholesterol in the sera of 1‐month‐old infants

Aim: To investigate why breastfed infants are more likely to have prolonged jaundice than formula‐fed infants. Methods: Serum unconjugated bilirubin (UCB), total cholesterol (TC) and triglyceride (TG) were measured for 102 infants of 1 month. Enrolled infants were 42 breastfed, 40 mixed‐fed and 20 bottle‐fed infants. Statistic analyses for relationship among UCB, TC, TG, perinatal factors and post‐natal factors were performed for these infants. Results: In correlation analyses UCB was correlated with peak transcutaneous bilirubin value in neonatal period (TcBn) (r = 0.612, P < 0.0001) and with TC (r = 0.383, P < 0.0001). When analyses of covariance (ANCOVA) for UCB were performed using TcBn as the covariate, the results indicated that there was neither significant main nor interaction effect of feeding method on UCB, and that main and interaction effects of TC on UCB were significant when TC was categorised into two groups (≤150 mg/dL and >150 mg/dL). Conclusions: It is suggested that both neonatal hyperbilirubinemia and subsequent higher plasma TC are associated factors for prolonged jaundice.     

Closure of aortopulmonary window using Nit‐Occlud® PDA‐R device in a 3‐month‐old infant

Aortopulmonary window (APW) is a rare abnormality in which a pulmonary defect exists between the ascending aorta and the main pulmonary artery. Given that it may result in cardiac failure and pulmonary vascular disease in the early period, treatment needs to be performed without delay. In addition to surgical treatment, transcatheter closure may also be performed for selected patients. This study describes the case of an infant diagnosed with APW and who underwent successful transcatheter closure using a Nit‐Occlud_®PDA‐R device.     

SIDS outdoors and seasonality in Sweden 1975–1987

In order to link the reported increasing incidence of SIDS in Sweden to environmental or other risk factors, we compared birth records and circumstances of deaths in infants who died in 1975–1977 with those who died a decade later, 1985–1987. The number of live births differed by only 6850 in these two periods. Data were acquired from autopsy records of the deceased infants and matched with their respective birth certificates which were obtained from the National Board of Health and Welfare. The reported postperinatal incidence of SIDS increased from 0.51 per 1000 in 1975–1977 to 0.93 per 1000 in 1985–1987. No significant differences in boy/girl ratio, birth weight, gestational age or age at death were found in the two periods. While the number of infants who died at night indoors in their own bed remained almost unchanged, the number of infants who died outdoors in baby carriages during the cold season increased almost four-fold. The observed increase in incidence could, to a large extent, be related to the increase in outdoor deaths. We speculate that increased incidence of smoking among young women as well as other changes in lifestyle may have been contributing factors.     

Primary orbital neuroblastoma in a 1‐month‐old boy

Neuroblastoma is a malignant tumor predominantly occurring in children and usually arising from the adrenal gland or sympathetic ganglia. We describe a neuroblastoma in a 1‐month‐old boy arising from his left orbital cavity. This tumor was refractory to chemotherapy or radiotherapy, requiring enucleation of the left eye for complete removal of the intraorbital tumor. Thereafter, he received high‐dose chemotherapy followed by autologous peripheral blood stem cell transplantation, and has been in complete remission for 3 years. Unlike neuroblastomas arising from the adrenal gland or sympathetic ganglia, primary orbital neuroblastoma may be refractory even in early infancy.     

Hepatocellular carcinoma in a 10‐month‐old biliary atresia child

Abstract: We present a case of a 10‐month‐old boy with BA who developed HCC and was treated with liver transplantation. A four‐month‐old boy was referred to our institution because of persistent jaundice, hepatomegaly, and coagulopathy. He had been treated for the diagnosis of neonatal hepatitis at an outside hospital. He was evaluated and was accepted as a liver transplant candidate, and was subsequently transplanted with a deceased donor liver allograft at the age of 10 months. His native liver showed established cirrhosis because of BA with one focus of moderately differentiated HCC, measuring 0.7 cm in a diameter with microscopic vascular invasion in pathological study. The postoperative course was uneventful, and he is well without recurrence four months after liver transplantation. The occurrence of HCC in a child under one yr old is extremely rare, and only three cases are reported so far including our case.
