Breastfeeding and risk of epilepsy in childhood: a birth cohort study

Human milk and breastfeeding during ketogenic diet therapy in infants with epilepsy: Clinical practice guideline

Ketogenic diet therapy (KDT) is a safe and effective treatment for epilepsy and glucose transporter type 1 (GLUT1) deficiency syndrome in infancy. Complete weaning from breastfeeding is not required to implement KDT; however, breastfeeding remains uncommon. Barriers include feasibility concerns and lack of referrals to expert centres. Therefore, practical strategies are needed to help mothers and professionals overcome these barriers and facilitate the inclusion of breastfeeding and human milk during KDT. A multidisciplinary expert panel met online to address clinical concerns, systematically reviewed the literature, and conducted two international surveys to develop an expert consensus of practical recommendations for including human milk and breastfeeding in KDT. The need to educate about the nutritional benefits of human milk and to increase breastfeeding rates is emphasized. Prospective real-world registries could help to collect data on the implementation of breastfeeding and the use of human milk in KDT, while systematically including non-seizure-related outcomes, such as quality of life, and social and emotional well-being, which could improve outcomes for infants and mothers.

Mother and newborn skin-to-skin contact and timely initiation of breastfeeding in sub-Saharan Africa

BACKGROUND

Mother and newborn skin-to-skin contact (SSC) plays a key role in breastfeeding practices of mothers. In this study, we examined the association between mother and newborn SSC and timely initiation of breastfeeding in sub-Saharan Africa (SSA).

METHODS

This cross-sectional study utilized nationally representative data from the Demographic and Health Surveys of 17 countries in SSA from 2015 to 2020. Multilevel binary logistic regression analysis was performed to examine the association between mother and newborn SSC and timely initiation of breastfeeding. The results are presented using adjusted odds ratios (aOR), with 95% confidence interval (CI).

RESULTS

The pooled prevalences of mother and newborn SSC and timely initiation of breastfeeding were 45.68% (95% CI = 34.12-57.23) and 62.89% (95% CI = 55.67-70.11), respectively. Mothers who practiced newborn SSC were more likely to practice timely initiation of breastfeeding compared to those who did not practice SSC [aOR = 1.68, 95% CI = 1.58, 1.78] and this persisted after controlling for all the covariates [aOR = 1.38, 95% CI = 1.29, 1.47]. At the country level, mother and newborn SSC increased the odds of timely initiation of breastfeeding in Angola [aOR = 1.99, 95% CI = 1.44, 2.76], Cameroon [aOR = 1.43, 95% CI = 1.02, 1.99], Ethiopia [aOR = 1.62, 95% CI = 1.16, 2.28], Guinea [aOR = 1.69, 95% CI = 1.10, 2.60], Liberia [aOR = 2.03, 95% CI = 1.33, 3.12], Malawi [aOR = 1.47, 95% CI = 1.02, 2.12], Mali [aOR = 1.42, 95% CI = 1.10, 1.84], Sierra Leone [aOR = 1.87, 95% CI = 1.23, 2.83], South Africa [aOR = 2.59, 95% CI = 1.41, 4.76], Tanzania [aOR = 1.60, 95% CI = 1.27, 2.01], Uganda [aOR = 1.43, 95% CI = 1.02, 1.99], Zambia [aOR = 1.86, 95% CI = 1.50, 2.30], and Zimbabwe [aOR = 1.65, 95% CI = 1.24, 2.21].

CONCLUSION

The prevalence of SCC was relatively low but timely initiation of breastfeeding was high. Mother and newborn SSC is a strong predictor of timely initiation of breastfeeding in SSA. To enhance timely initiation of breastfeeding after birth, this study recommends that more child and maternal healthcare interventions focused on improving mother and newborn SSC should be implemented.

The effect of hospital phototherapy on early breastmilk feeding

BACKGROUND

The effect of phototherapy on breastmilk feeding is unclear.

OBJECTIVE

To estimate the effect of inpatient phototherapy on breastmilk feeding at 2-month well-child visits.

METHODS

We performed a retrospective cohort study using electronic health record data. From births at 16 Kaiser Permanente Northern California hospitals (2013-2017), we identified a cohort of infants ≥ 35 weeks' gestation with total serum bilirubin levels close to the American Academy of Pediatrics 2004 phototherapy threshold during their birth hospitalisation. We compared self-reported breastmilk feeding at 2-month well-child visits among those who had and had not received birth hospitalisation phototherapy, adjusting for bilirubin levels and other confounding variables. We used multiple imputation (K = 200) to address missing data.

RESULTS

Approximately a quarter of infants in the cohort (24.5%) received phototherapy during their birth hospitalisation. At the 2-month visit, exclusive breastmilk feeding was less common (RR 0.91, 95% interval [CI] 0.88, 0.95) among those who received phototherapy (41.3%) than those who did not (45.2%). However, no association remained after adjusting for potential confounders (RR 0.99, 95% CI 0.95, 1.04; average treatment effect on the treated [ATET] -0.2%, 95% CI -2.0%, 1.5%). In contrast, any breastmilk feeding was similar between infants who did (76.8%) and did not get phototherapy (77.9%). After adjusting for confounders, phototherapy had a slightly positive association with any breastmilk feeding at 2 months (RR 1.02, 95% CI 1.00, 1.04). Among infants who received phototherapy, the proportion being fed any breastmilk at the 2-month visit was an estimated 1.6 percentage points higher than it would have been if they had not received phototherapy (ATET 1.6%, 95% CI 0.1%, 3.1%). Multiple imputation results were similar.

CONCLUSIONS

Birth hospitalisation phototherapy can be delivered in a way that does not adversely affect breastmilk feeding at 2 months.

Breastfeeding technique and associated factors among lactating mothers visiting Gondar town health facilities, Northwest Ethiopia: observational method

BACKGROUND

The breastfeeding technique is explained positioning, attachment, and suckling during breastfeeding. Ineffective breast feeding technique is one of the factors leading to premature discontinuation of breastfeeding and malnutrition. There is a limited study on the assessments of BFT and associated factors among lactating mothers in the study area. Therefore, the study aimed to assess breastfeeding technique and the associated factors among lactating mothers visiting Gondar town health facilities, Northwest Ethiopia.

METHODS

An institution-based cross-sectional study was conducted from February 20 to March 20, 2020. An observational checklist and structured interviewer-administered questionnaire were applied to collect the data. The data were entered into Epi-Data 4.6 version and transferred to analyzed using SPSS version 20. Bi-variable and multivariable logistic regressions were performed to identify the association. The strength of association was identified using odds ratio with a 95% confidence interval (), and a p-value of 0.05 was declare as statistically significant.

RESULTS

The proportion of effective BFT was 48% (95%, CI: 43.0-53.0%). The likelihood of applying proper BFT among age group of 18-20 years was 70% lower than (AOR = 0.3; 95% CI: 0.11-0.83) age group > 30 years. The odds of effective BFT in primipara mothers were 49% (AOR = 0.51; 95% CI: 0.32-0.82) lower compared to multiparous mothers. Likewise, the provability of effective BFT was 55% (AOR = 0.45; 95% CI: 0.29-0.70) times lower in women who had no counseling immediately after delivery compared to their counterparts. Moreover, effective breast feeding technique mothers who have breast problem was 78% lower than (AOR = 0.22; 95% CI: 0.07-0.68) mothers who have no breast problem. And mothers who had counselling of BFT during ANC follow up was 55% (AOR = 0.45; 95% CI: 0.29, 0.70) lower than mothers who had no counseling.

CONCLUSION

Just under half of the women in the study area applied proper breast feeding technique Younger and primipara mothers poorly performed to effective BFT. But women having counseling during antenatal care follow-up and immediately after delivery and not having breast problems applied BFT effectively. Hence, special emphasis have to give for younger and primipara mothers. Besides, educate the mother for preventing breast problems and working on enhancing counseling at postnatal clinic.

Breastmilk Feeding during the First 4 to 6 Months of Age and Childhood Disease Burden until 10 Years of Age

BACKGROUND

Breastfeeding is recommended due to its beneficial effects on human health. However, the effect of breastfeeding on health differs, resulting in various childhood diseases.

OBJECTIVE

Our purpose was to investigate the association between breastfeeding at least in the first 4 months and the subsequent development of 15 certainly defined childhood diseases until 10 years of age, the all-cause hospitalization rate and growth at 6-7 years of age.

METHODS

Participants included propensity-score matched 188,052 children born between January 2008 and December 2009, who were followed up till 10 years of age. Data were taken from the National Investigation of birth Cohort in Korea study 2008 database. Risk ratios were obtained using a modified Poisson regression and weighted risk differences using binomial regression.

RESULTS

Compared to formula feeding, breastfeeding was associated with decreased risks of febrile convulsion, attention deficit hyperactivity disorder and autism spectrum disorder, pneumonia, acute bronchiolitis, hypertrophic pyloric stenosis, asthma, all-cause hospitalization, overweight/obesity and short stature. Exclusive breastfeeding at 4 to 6 months of age had similar results to exclusive breastfeeding over 6 months of age.

CONCLUSIONS

Breastfeeding in early infancy reduces the risk for various childhood diseases, all-cause hospitalization rate, obesity, and short stature during childhood.

Epigenome-Wide Association Study Reveals Duration of Breastfeeding Is Associated with Epigenetic Differences in Children

Several small studies have shown associations between breastfeeding and genome-wide DNA methylation (DNAm). We performed a comprehensive Epigenome-Wide Association Study (EWAS) to identify associations between breastfeeding and DNAm patterns in childhood. We analysed DNAm data from the Isle of Wight Birth Cohort at birth, 10, 18 and 26 years. The feeding method was categorized as breastfeeding duration >3 months and >6 months, and exclusive breastfeeding duration >3 months. EWASs using robust linear regression were performed to identify differentially methylated positions (DMPs) in breastfed and non-breastfed children at age 10 (false discovery rate of 5%). Differentially methylated regions (DMRs) were identified using comb-p. The persistence of significant associations was evaluated in neonates and individuals at 18 and 26 years. Two DMPs, in genes SNX25 and LINC00840, were significantly associated with breastfeeding duration >6 months at 10 years and was replicated for >3 months of exclusive breastfeeding. Additionally, a significant DMR spanning the gene FDFT1 was identified in 10-year-old children who were exposed to a breastfeeding duration >3 months. None of these signals persisted to 18 or 26 years. This study lends further support for a suggestive role of DNAm in the known benefits of breastfeeding on a child's future health.

The ketogenic diet for infants: How long can you go?

PURPOSE

Ketogenic diets (KD) are high-fat, low-carbohydrate therapies, established in the treatment for drug-resistant epilepsy in childhood since the 1920ies. This review focuses on the use of ketogenic diet therapies in young childhood with an emphasis on the most recent advances.

FINDINGS

The KD has been used effectively and safely in childhood, and has increasingly been offered in infancy during the last decade. The introduction of a KD is recommended with a fixed fat/ non-fat ratio of 3:1, modified if necessary. In infants the KD is initiated without fasting and fluid restriction and with a shorter treatment duration than in older children. Twenty studies that also included infants below 1 year of age are available. When the KD is used early and in an approach based on syndromes and etiology, seizure freedom is achieved and maintained more often than when used as last ressort. In infants with genetic causes already recognized in early infancy, the KD has shown to be even more effective. Most frequent adverse effects in infancy include emesis, hypoglycemia, food/ liquid refusal and constipation which are mostly transient and resolvable by dietary adjustments. Promising data on the inclusion of expressed breast milk to the KD and maintaining actual breastfeeding while on the KD have shown that complete weaning from breast-feeding is not necessary and inclusion of breast milk as well as breastfeeding should be encouraged.

SUMMARY

The ketogenic diet is a versatile therapy, and effective and safe in its use in infancy. There is growing evidence and guidelines that specify indications where the KD should be used early.

The Ketogenic Diet Including Breast Milk for Treatment of Infants with Severe Childhood Epilepsy: Feasibility, Safety, and Effectiveness

Objective: The ketogenic diet (KD) is a high-fat and restricted carbohydrate diet for treating severe childhood epilepsy. In infants, breast milk is usually fully replaced by a ketogenic formula. At our center, mothers are encouraged to include breastfeeding into the KD if still breastfeeding. This retrospective study describes achievement and maintenance of ketosis with or without inclusion of breast milk. Methods: Data were retrieved from a prospective longitudinal database of children treated with KD for epilepsy analyzing infants <1 year of age. The time to achieve clinically relevant ketosis (≥2 mmol/L beta-hydroxybutyrate) was compared with and without inclusion of breast milk into standard KD. Ketosis, nutritional intakes, effectiveness, adverse effects, and successful continuation of breastfeeding were evaluated. Results: A total of 79 infants were eligible for analysis. In 20% (16), breast milk was included. Infants with breast milk included into the KD achieved relevant ketosis in 47 hours (interquartile range [IQR] 24-95) compared with 41 hours (IQR 22-70; p = 0.779) in infants with standard KD. Beta-hydroxybutyrate at day 2 was 3.1 mmol/L (IQR 0.5-4.9) and 3.8 mmol/L (IQR 2.2-4.9). Infants with breast milk included received higher amounts of carbohydrates at baseline and calories at 3 months. Seizure freedom and adverse effects showed no relevant differences. No infections occurred in infants receiving breast milk. In two infants, KD was initiated with breast-feds after bottle-feeding KD formula. In 31%, breastfeeding was continued after the KD, and in 25%, inclusion of breast milk and breastfeeding was maintained until complete weaning. Before discharge from hospital, the amount of breast milk included was median 90 mL/day (IQR 53-203) equivalent to median 9% (IQR 6-15). Conclusions: Appropriate ketosis was achieved in most infants and maintained within 48 hours. Incorporation of breast milk into KD is feasible, safe, and effective.

Childhood Seizures After Phototherapy

: media-1vid110.1542/5804915133001PEDS-VA_2018-0648Video Abstract BACKGROUND AND OBJECTIVES: In a recent Danish study, researchers found an increased risk of childhood epilepsy after phototherapy but only in boys. We investigated this association in a Kaiser Permanente Northern California cohort.

METHODS

From 499 642 infants born at ≥35 weeks' gestation in 1995-2011 followed for ≥60 days, we excluded 1773 that exceeded exchange transfusion thresholds and 1237 with seizure diagnoses at <60 days. We ascertained phototherapy, covariates, and outcomes from electronic records and existing databases. Our primary outcome was ≥1 encounter with a seizure diagnosis plus ≥1 prescription for an antiepileptic drug. We used Cox and Poisson models to adjust for bilirubin levels and other confounding variables.

RESULTS

A total of 37 683 (7.6%) infants received any phototherapy. The mean (SD) follow-up time was 8.1 (5.2) years. The crude incidence rate per 1000 person-years of the primary outcome was 1.24 among phototherapy-exposed children and 0.76 among those unexposed (rate ratio: 1.63; 95% confidence interval [CI]: 1.44 to 1.85). The adjusted hazard ratio (aHR) was 1.22 (95% CI: 1.05 to 1.42; P = .009). Boys were at higher risk of seizures overall (aHR = 1.18; 95% CI: 1.10 to 1.27) and had a higher aHR for phototherapy (1.33; 95% CI: 1.10 to 1.61) than girls (1.07; 95% CI: 0.84 to 1.37), although effect modification by sex was not statistically significant (P = .17). The adjusted 10-year excess risks per 1000 were 2.4 (95% CI: 0.6 to 4.1) overall, 3.7 (95% CI: 1.2 to 6.1) in boys, and 0.8 (95% CI: -1.7 to 3.2) in girls.

CONCLUSIONS

Phototherapy in newborns is associated with a small increased risk of childhood seizures, even after adjusting for bilirubin values, and the risk is more significant in boys.

An acidosis-sparing ketogenic (ASK) diet to improve efficacy and reduce adverse effects in the treatment of refractory epilepsy

Diets that increase production of ketone bodies to provide alternative fuel for the brain are evolving from the classic ketogenic diet for epilepsy devised nearly a century ago. The classic ketogenic diet and its more recent variants all appear to have similar efficacy with approximately 50% of users showing a greater than 50% seizure reduction. They all require significant medical and dietetic support, and there are tolerability issues. A review suggests that low-grade chronic metabolic acidosis associated with ketosis is likely to be an important contributor to the short term and long term adverse effects of ketogenic diets. Recent studies, particularly with the characterization of the acid sensing ion channels, suggest that chronic metabolic acidosis may increase the propensity for seizures. It is also known that low-grade chronic metabolic acidosis has a broad range of negative health effects and an increased risk of early mortality in the general population. The modified ketogenic dietary treatment we propose is formulated to limit acidosis by measures that include monitoring protein intake and maximizing consumption of alkaline mineral-rich, low carbohydrate green vegetables. We hypothesize that this acidosis-sparing ketogenic diet is expected to be associated with less adverse effects and improved efficacy. A case history of life-long intractable epilepsy shows this diet to be a successful long-term strategy but, clearly, clinical studies are needed.

The costs of inadequate breastfeeding of infants in Mexico

BACKGROUND

Breastfeeding is vital for child survival, health, and development. Mexico has very low rates of breastfeeding and experienced a severe decrease in the prevalence of exclusive breastfeeding from 21% in 2006 to 14% in 2012.

OBJECTIVE

The objective of the article was to estimate the pediatric costs of inadequate breastfeeding in Mexico associated with the following acute health conditions: respiratory infections, otitis media, gastroenteritis, necrotizing enterocolitis (NEC), and sudden infant death syndrome (SIDS).

DESIGN

The authors estimated the economic costs of inadequate breastfeeding as follows: the sum of direct health care costs for diseases whose risk increases when infants are non-exclusively breastfed <6 mo or are not breastfed from ages 6 to <11 mo, lost future earnings due to premature infant death, and the costs of purchasing infant formula. Incidence cases were retrieved from national surveillance systems, except for NEC and SIDS, which were estimated from the literature. A sensitivity analysis was carried out to provide a range of costs based on different assumptions of the number of incident cases of all infant health outcomes examined. The model applied to the cohort of 1-y-old children born in 2012.

RESULTS

The total annual costs of inadequate breastfeeding in Mexico for the studied cohort ranged from $745.6 million to $2416.5 million, where the costs of infant formula accounted for 11-38% of total costs. A range of 1.1-3.8 million reported cases of disease and from 933 to 5796 infant deaths per year for the diseases under study are attributed to inadequate infant breastfeeding practices; altogether these represent nearly 27% of the absolute number of episodes of such diseases.

CONCLUSIONS

This study provides costs of inadequate breastfeeding that had not been quantified in Mexico. The costs presented in this article provide the minimum amount that the country should invest to achieve better breastfeeding practices.
