White, PhD, Philip M. Farrell, MD, PhD, Bruce C. Marshall, MD, and Frank J. Accurso, MD Newborn screening for cystic fibrosis (CF) offers the opportunity for early medical and nutritional intervention that can lead to improved outcomes. Management of the asymptomatic infant diagnosed with CF through newborn screening, prenatal diagnosis, or sibling screening is different from treatment of the symptomatically diagnosed in- dividual. The focus of management is on maintaining health by preventing nutritional and respiratory complications. The CF Foundation convened a committee to develop recommendations based on a systematic review of the ev- idence and expert opinion. These guidelines encompass monitoring and treatment recommendations for infants diagnosed with CF and are intended to help guide families, primary care providers, and specialty care centers in the care of infants with CF. (J Pediatr 2009;155:S73-93). ymptomatic diagnosis of cystic fibrosis (CF) is associated with short- and long-term complications including failure to thrive, stunting, wasting, vitamin and mineral deficiencies, recurrent pulmonary infections associated with decreased Slung function, and recurrent hospitalizations. Early identification of CF by newborn screening (NBS), prenatal diagnosis, or family history offers the opportunity to delay and potentially prevent many of these complications through early treatment. Although many treatment issues are the same for individuals with CF regardless of when they are diagnosed, some are unique to the population of newborn infants who may not have overt symptoms of the disease before referral to the CF care center. The CF Foundation convened a committee of experts to develop guidelines for care based on currently available evidence for this distinct population of newly diagnosed infants. Methods The CF Foundation convened a group of experts to identify issues in the care of infants with CF and commissioned an evidence review from Johns Hopkins University. Details of this evidence review, including methods and results, are provided in the ac- companying article.1 Committee members assessed this evidence in developing recommendation statements and, where pos- sible, made evidence-based recommendations. Recommendations were graded using the United States Preventive Health Services Task Force (USPSTF) grading system.2 Recommendations from published guidelines were used if available and appro- priate. The committee made consensus recommendations for topics not included in the evidence review, for topics where prior guidelines were available, and for topics for which there was limited or no evidence but the potential net benefit was assessed as at least moderate (Table I). A draft of the guidelines was posted on a secure web site for comment from CF Center care teams (physicians and ancillary care providers) and was revised as appropriate. As per the CF Foundation guidelines process, these guidelines will be assessed within 3 years to determine if revisions are necessary.

  • Vitamin E Deficiency and Associated Factors Among Brazilian School Children Deficiência De Vitamina E E Fatores Associados Entre Crianças Escolares Brasileiras
    Artigo Original Vitamin E deficiency and associated factors among Brazilian school children Deficiência de vitamina E e fatores associados entre crianças escolares brasileiras Viviane Imaculada do Carmo Custódio1 , Carlos Alberto Nogueira-de-Almeida2 , Luiz Antonio Del Ciampo3 , Fábio da Veiga Ued4 , Ane Cristina Fayão Almeida5 , Rodrigo José Custódio6 , Alceu Afonso Jordão Júnior7 , Júlio César Daneluzzi8 , Ivan Savioli Ferraz9 ABSTRACT Objective: Brazilian national data show a significant deficiency in pediatric vitamin E consumption, but there are very few studies evaluating laboratory-proven nutritional deficiency. The present study aimed to settle the prevalence of vitamin E deficiency (VED) and factors associated among school-aged children attended at a primary health unit in Ribeirão Preto (SP). Methods: A cross-sectional study that included 94 children between 6 and 11 years old. All sub- jects were submitted to vitamin E status analysis. To investigate the presence of factors associated with VED, socio- economic and anthropometric evaluation, determination of serum hemoglobin and zinc levels, and parasitological stool exam were performed. The associations were performed using Fisher’s exact test. Results: VED (α-tocopherol concentrations <7 μmol/L) was observed in seven subjects (7.4%). None of them had zinc deficiency. Of the total of children, three (3.2%) were malnourished, 12 (12.7%) were anemic, and 11 (13.5%) presented some pathogenic intestinal parasite. These possible risk factors, in addition to maternal-work, maternal educational level, and monthly income, were not associated with VED. Conclusions: The prevalence of VED among school-aged children attended at a primary health unit was low. Zinc deficiency, malnutrition, anemia, pathogenic intestinal parasite, maternal-work, maternal educational level, and monthly income were not a risk factor for VED.

The objective was to evaluate the impact of home fortification with powdered micronutrients on α-tocopherol concentrations, growth, and inflammation in Brazilian children aged 6–15 months. This is a pragmatic, controlled clinical trial, in which the intervention group received micronutrient powder sachets for up to 3 months. Vitamin E deficiency was considered when α-tocopherol was less than 11.6 µmol/L. The Poisson regression model was used to estimate adjusted values for prevalence ratios (PR) for the outcome variable. A total of 224 children participated in the study. The intervention group had a higher median α-tocopherol level (17.2 versus 3.6 µmol/L; p < 0.001) and an 82.0% reduction in the prevalence of vitamin deficiency (PR = 0.18; 95% CI 0.11–0.30) when compared with the control group.

Since prothrombin time is a surrogate marker, it may underestimate the actual prevalence of vitamin K deficiency in this population. This study investigates the frequency of vitamin K deficiency among a convenience sample of children and adults with cholestatic liver disease by determining plasma levels of protein induced in vitamin K absence II (PIVKA-II), and assesses the relationship between PIVKA-II levels and markers of cholestasis, measured prothrombin time, and vitamin A, E and 25-hydroxyvitamin D levels. Methods: Subjects with cholestatic liver disease were recruited from the Cincinnati referral area. Subjects with decompensated cirrhosis, malignancy, concurrent disease that results in fat malabsorption and AIDS were excluded. All subjects had blood collected for liver function tests, prothrombin time (PT), INR, bile acids, 25-hydroxyvitamin D, vitamin A, vitamin E and PIVKA-II levels.

Miller1 & Gabriela Trifan1 & Fernando D. Testai1 # Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract Purpose of Review The goal of this chapter is to educate clinicians on the neurologic manifestations of certain nutritional deficiencies in order to promptly identify and appropriately treat these patients. Recent Findings Many vitamin and nutritional deficiencies have been described dating back to the early days of neurology and medicine. Some are very rare and thus, there are no randomized controlled studies to assess supplementation or dosage; however, there are reviews of case reports that can assist clinicians in choosing treatments. Summary While endemic vitamin and nutritional deficiencies may be rarely encountered in many countries, vulnerable popu- lations continue to be at risk for developing neurologic complications. These populations include those with diseases causing malabsorption, the elderly, chronic alcohol users, as well as pregnant mothers with hyperemesis gravidarum to name a few. It is important to recognize syndromes associated with these nutritional deficiencies, as prompt identification and treatment may prevent permanent neurologic damage. Keywords Vitamin deficiency .

Singhi** Departments of Neurology* and Peadiatric Medicine**, Post Graduate Institute of Medical Education and Research, Chandigarh-160012 ABSTRACT Prevalence of malnutrition is a global phenomenon but the greatest contribution towards it is from the developing countries. Malnutrition impairs physical growth, cognitive functions of brain, physiological functions, immune response changes. Twenty Seven percent of children under 5 years are malnourished in the developing countries. India contributes to approximately 5.6 million child deaths annually with almost one billion children dying worldwide from the consequences of malnutrition. Malnutrition produces lasting effect on developing brain during the “Brain growth spurt’’ phase which corresponds to the period from 30 weeks of gestation to two-year of post natal age. In the peripheral nervous system the growth of axons, migration of Schwann cells and onset of myelination starts at 14 to 20 weeks of gestation. Malnutrition causes muscle wasting, hypotonia and impaired deep tendon reflexes from 30-40% of malnourished children. Deficiency of micronutrients in malnourished can cause myelopathy, peripheral neuropathy, dementia, infantile seizures, infantile tremor syndrome, night blindness, optic neuropathy and spinocerebellar degeneration.

This review first discussed some reduction potential-based biochemical activities of vitamin C such as assisting the post-translational collagen modification as well as acting as an antioxidant and pro-oxidant. These known activities of vitamin C were then used to address recent outcomes of vitamin C clinical trials on the prevention and treatment of non-scurvy diseases such as cardiovascular diseases and cancer. The pro-oxidant activity may contribute to the adverse effect of high-level vitamin C supplementation in clinical trials.
