Niemann–Pick type C1 (NPC1) disease is a rare genetic condition in which the function of the lysosomal cholesterol transporter NPC1 protein is impaired. Consequently, sphingolipids and cholesterol accumulate in lysosomes of all tissues, triggering a cascade of pathological events that culminate in severe systemic and neurological symptoms. Lysosomal cholesterol accumulation is also a key-factor in the development of atherosclerosis and non-alcoholic steatohepatitis (NASH). In these two metabolic diseases, the administration of plant stanol esters has been shown to ameliorate cellular cholesterol accumulation and inflammation. Given the overlap of pathological mechanisms among atherosclerosis, NASH and NPC1 disease, we sought to investigate whether dietary supplementation with plant stanol esters improves the peripheral features of NPC1 disease. To this end, we used an NPC1 murine model featuring an Npc1 null allele (Npc1^nih), creating a dysfunctional NPC1 protein. Npc1^nih mice were fed a two or six percent plant stanol esters–enriched diet over the course of 5 weeks. During this period, hepatic and blood lipid and inflammatory profiles were assessed. Npc1^nih mice fed the plant stanol–enriched diet exhibited lower hepatic cholesterol accumulation, damage and inflammation than regular chow–fed Npc1^nih mice. Moreover, plant stanol consumption shifted circulating T-cells and monocytes in particular towards an anti-inflammatory profile. Overall, these effects were stronger following dietary supplementation with 6% stanols, suggesting a dose-dependent effect. The findings of our study highlight the potential use of plant stanols as an affordable complementary means to ameliorate disorders in hepatic and blood lipid metabolism and reduce inflammation in NPC1 disease.

Docosahexaenoic acid is important for fetal brain development and visual acuity in infants. Infants born prematurely are at particular risk for docosahexaenoic acid insufficiency because they may not have benefited from a full trimester of the mother's lipid stores.

This is the first study in which the administration of fish-oil lipid emulsion in very low birth weight infants from the first day of life is described. The influence of fish-oil lipid emulsion on the regression of retinopathy seems to be worthy of further investigation. (Read the full article)

Bronchiolitis is the most common cause for hospital admission in patients aged <1 year. Hypoxia is a common reason for admission. Despite a multitude of studies looking at various treatment strategies, no clear benefit has been found.

With oxygen therapy being the main therapeutic option, home oxygen offers a novel way to manage bronchiolitis. This study shows that home oxygen is a safe and effective way to decrease hospital admissions in a select group of patients. (Read the full article)

Impaired fetal growth is an independent risk factor for cardiovascular diseases in adulthood and is associated with arterial wall thickening, a noninvasive measure of subclinical atherosclerosis, in early childhood. No preventive strategy has been identified.

Dietary omega-3 fatty acid supplementation in early childhood prevented the association of impaired fetal growth with arterial wall thickening, suggesting that this early-life intervention may mitigate the risk of cardiovascular disease in those with impaired fetal growth. (Read the full article)

Postpartum vitamin A supplementation is a strategy to combat vitamin A deficiency and seems to reduce maternal/infant morbidity and mortality. However, controversies exist regarding which dose has a greater efficacy, 200 000 IU (WHO protocol) or 400 000 IU (IVACG protocol).

In this study, postpartum maternal supplementation with 400 000 IU of vitamin A did not provide any additional beneficial effect in reducing infant morbidity compared with the standard dose of 200 000 IU. (Read the full article)

During prenatal counseling for prematurity, information is provided to expectant parents to empower them to participate in the medical-care decision-making regarding their child. However, numerous studies have shown that providing information effectively during preterm labor is challenging.

The current study provides evidence that effectiveness of counseling can be improved by providing written information to parents before the face-to-face verbal counseling. Appropriately presented, detailed information improves knowledge and decreases maternal anxiety. (Read the full article)

Cholestasis predisposes to the development of fat-soluble vitamin (FSV) deficiency. D-α tocopheryl polyethylene glycol-1000 succinate and coadministered FSVs are absorbed in spite of cholestasis.

Infants with biliary atresia with total bilirubin >2 mg/dL are at risk for fat-soluble vitamin (FSV) deficiency. A multivitamin preparation containing d-α tocopheryl polyethylene glycol-1000 succinate alone is not effective in treating biochemical FSV insufficiency in cholestatic infants.

Micronutrients are essential for brain development during gestation and infancy. Few randomized trials of maternal multiple micronutrient supplementation during pregnancy and postpartum have examined child outcomes beyond the neonatal period or tested which cognitive domains show long-term effects.

Children of undernourished mothers given multiple micronutrients performed as well as children of well-nourished mothers in motor and visual attention/spatial ability at age 42 months; children of undernourished mothers given iron/folic acid showed 4- to 5-month delays in these abilities.

A growing number of epidemiologic studies suggest that individuals with lower vitamin D levels are at higher risk of acute respiratory tract infection. Randomized controlled trials are needed to determine if vitamin D supplementation would decrease this risk.

In a randomized controlled trial of 247 Mongolian children with vitamin D deficiency in winter, with double-blinding and 99% follow-up, vitamin D supplementation significantly reduced the risk of acute respiratory tract infections. (Read the full article)

Declining dietary omega 3 polyunsaturated fatty acids has been associated with rising allergy prevalence and fish oil is therefore of interest in allergy prevention. Supplementation during pregnancy, but not after the age of 6 months, has achieved some allergy reductions.

We assessed the effect of fish oil supplementation from birth to 6 months, which has not been investigated previously. Our results, together with previous findings, will likely help define a "window of opportunity" for allergy intervention using fish oil supplements. (Read the full article)

Despite numerous preventive strategies including prophylaxis with 400 IU/day of vitamin D in recent years, the deficiency of vitamin D in infants is still a global health problem.

This study reveals that the risk of vitamin D deficiency is high in exclusively breastfed infants, especially in winter, despite vitamin D supplementation. Therefore, it is suggested that an adjustment of vitamin D dosage for seasonal variation might be necessary. (Read the full article)

Low birth weight (LBW) infants (<2500 g) are at risk for cognitive and behavioral problems later in life. During infancy, they are also at risk for iron deficiency, which has been associated with impaired neurodevelopment in other high-risk groups.

Iron supplementation during the first 6 months of life to LBW infants reduces the risk of behavioral problems at 3.5 years. Mild iron deficiency in infancy may be an important, preventable contributor to behavioral problems in children born with LBW. (Read the full article)

The American Academy of Pediatrics recommends that infants <1500 g birth weight receive an iron intake of 4 mg/kg per day. There are no randomized trials to support this recommendation.

This trial compared the effect of iron supplementation of 2 mg/kg per day on the hematocrit at 36 weeks' postmenstrual age. This study concluded that iron supplementation does not affect the 36-week hematocrit or the number of transfusions in infants <1500 g. (Read the full article)

Randomized controlled trials have shown that zinc supplementation during diarrhea substantially reduces the incidence and severity. However, the effect of short-course prophylactic zinc supplementation has been observed only in children >12 months of age.

The current study was able to show that short-course prophylactic zinc supplementation significantly reduced diarrhea morbidity in apparently healthy infants of 6 to 11 months even after 5 months of follow-up. (Read the full article)

Hypovitaminosis D is common among children. Although there is prolific biochemical literature linking vitamin D to enteric immunologic function, there is a paucity of prospective data exploring the role of supplementation in prevention of diarrheal illnesses.

In a high-risk population, quarterly supplementation with 100 000 IU of vitamin D₃ did not reduce the risk for first or recurrent diarrheal illnesses in a population of children aged 1 to 29 months in a low-income inner city setting. (Read the full article)

Despite widespread prevalence of vitamin D deficiency, there is a paucity of evidence on the appropriate supplemental dose in preterm infants. Various professional organizations empirically recommend different doses of vitamin D, ranging from 400 to 1000 IU per day.

Daily vitamin D supplementation at a dose of 800 IU compared with 400 IU significantly reduces the prevalence of vitamin D deficiency in preterm infants. The clinical significance of achieving vitamin D sufficiency needs to be studied in larger trials. (Read the full article)

Prenatal lipid-based nutrient supplementation has been demonstrated to increase birth length. However, the impact of this intervention on infant growth and morbidity is unknown.

Infants from mothers who were given prenatal lipid-based nutrient supplements showed decelerated linear growth. The gain in length at birth related to prenatal lipid-based nutrient supplementation was not sustained during infancy. (Read the full article)

Recent studies have shown that participating in the Supplemental Nutrition Assistance Program (SNAP) is associated with improved household food security. With the exception of 1 descriptive analysis, studies have not examined how SNAP affects children’s food security.

This article estimates the association between SNAP and children’s food security using the largest, most rigorous national study of food security to date. Given current proposals to reduce program size, this study underscores SNAP’s importance in affecting children’s well-being. (Read the full article)

The vitamin D concentration in breast milk of women taking 400 IU vitamin D per day is relatively low, leading to vitamin D deficiency in breastfeeding infants. As a result, the American Academy of Pediatrics recommends breastfeeding infant vitamin D supplementation within days after birth.

Maternal vitamin D supplementation alone with 6400 IU/day safely supplies breast milk with adequate vitamin D to satisfy the requirement of her nursing infant and offers an alternate strategy to direct infant supplementation. (Read the full article)

BACKGROUND:

Mexican-origin women breastfeed at similar rates as white women in the United States, yet they usually breastfeed for less time. In our study, we seek to identify differences in Mexican-origin women’s breastfeeding intentions, initiation, continuation, and supplementation across nativity and country-of-education groups.

In iron-depleted women without anemia, oral iron supplements induce an increase in serum hepcidin (SHep) that persists for 24 hours, decreasing iron absorption from supplements given later on the same or next day. Consequently, iron absorption from supplements is highest if iron is given on alternate days. Whether this dosing schedule is also beneficial in women with iron-deficiency anemia (IDA) given high-dose iron supplements is uncertain. The primary objective of this study was to assess whether, in women with IDA, alternate-day administration of 100 and 200 mg iron increases iron absorption compared to consecutive-day iron administration. Secondary objectives were to correlate iron absorption with SHep and iron status parameters. We performed a cross-over iron absorption study in women with IDA (n=19; median hemoglobin 11.5 mg/dL; mean serum ferritin 10 mg/L) who received either 100 or 200 mg iron as ferrous sulfate given at 8 AM on days 2, 3 and 5 labeled with stable iron isotopes 57Fe, 58Fe and 54Fe; after a 16-day incorporation period, the other labeled dose was given at 8 AM on days 23, 24 and 26 (days 2, 3 and 5 of the second period). Iron absorption on days 2 and 3 (consecutive) and day 5 (alternate) was assessed by measuring erythrocyte isotope incorporation. For both doses, SHep was higher on day 3 than on day 2 (P<0.001) or day 5 (P<0.01) with no significant difference between days 2 and 5. Similarly, for both doses, fractional iron absorption (FIA) on days 2 and 5 was 40-50% higher than on day 3 (P<0.001), while absorption on day 2 did not differ significantly from day 5. There was no significant difference in the incidence of gastrointestinal side effects comparing the two iron doses (P=0.105). Alternate day dosing of oral iron supplements in anemic women may be preferable because it sharply increases FIA. If needed, to provide the same total amount of iron with alternate day dosing, twice the daily target dose should be given on alternate days, as total iron absorption from a single dose of 200 mg given on alternate days was approximately twice that from 100 mg given on consecutive days (P<0.001). In IDA, even if hepatic hepcidin expression is strongly suppressed by iron deficiency and erythropoietic drive, the intake of oral iron supplements leads to an acute hepcidin increase for 24 hours. The study was funded by ETH Zürich, Switzerland. This study has been registered at www.clinicaltrials.gov as #NCT03623997.

Tobacco smoking is the primary risk factor for lung cancer, driven by the addictive nature of nicotine and the indisputable carcinogenicity of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) as well as other compounds. The integration of lung cancer chemoprevention with smoking cessation is one potential approach to reduce this risk and mitigate lung cancer mortality. Experimental data from our group suggest that kava, commonly consumed in the South Pacific Islands as a beverage to promote relaxation, may reduce lung cancer risk by enhancing NNK detoxification and reducing NNK-derived DNA damage. Building upon these observations, we conducted a pilot clinical trial to evaluate the effects of a 7-day course of kava on NNK metabolism in active smokers. The primary objective was to compare urinary total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL plus its glucuronides, major metabolites of NNK) before and after kava administration as an indicator of NNK detoxification. Secondary objectives included determining kava's safety, its effects on DNA damage, tobacco use, and cortisol (a biomarker of stress). Kava increased urinary excretion of total NNAL and reduced urinary 3-methyladenine in participants, suggestive of its ability to reduce the carcinogenicity of NNK. Kava also reduced urinary total nicotine equivalents, indicative of its potential to facilitate tobacco cessation. Plasma cortisol and urinary total cortisol equivalents were reduced upon kava use, which may contribute to reductions in tobacco use. These results demonstrate the potential of kava intake to reduce lung cancer risk among smokers.
