Background Prostaglandin E2 (PGE2) plays a major role both in maintaining patency of the fetal ductus arteriosus (DA) and in closure of the DA after birth. The rate- limiting step in PGE2 signal termination is PGE2 uptake by the transporter PGT. Methods and results To determine the role of PGT in DA closure, we used a gene-targeting strategy to produce mice in which PGT exon 1 was flanked by loxP sites. Successful targeting was obtained since neither mice hypomorphic at the PGT allele (PGT Neo/Neo) nor global PGT knockout mice (PGT −/−) exhibited PGT protein expression; moreover, embryonic fibroblasts isolated from targeted mice failed to exhibit carrier-mediated PGE2 uptake. Although born in a normal Mendelian ratio, no PGT −/− mice survived past post-natal day 1, and no PGT Neo/Neo mice survived past post-natal day 2. Necropsy revealed patent DA with normal intimal thickening but with dilated cardiac chambers. Both PGT Neo/Neo and PGT −/− mice could be rescued through the post-natal period by giving the mother indomethacin before birth. Rescued mice grew normally and had no abnormalities by gross and microscopic post-mortem analysis. In accord with PGT’s known role in metabolizing PGE2, rescued adult PGT −/− mice had lower plasma PGE2 metabolite levels, and higher urinary PGE2 excretion rates, than wild type mice. Conclusions PGT plays a critical role in closure of the DA after birth by ensuring a reduction in local and/or circulating PGE2 concentrations. PMID:20083684

Previous research has identified potential issues of establishing and maintaining breastfeeding among women who experience severe maternal morbidity associated with pregnancy and birth, but evidence in the UK maternity population was scarce. We explored the association between severe maternal morbidity and breastfeeding outcomes (uptake and prevalence of partial and exclusive breastfeeding) at 6 to 8 weeks post-partum in a UK sample. Data on breastfeeding outcomes were obtained from a large cohort study of women who gave birth in one maternity unit in England to assess the impact of women's experiences of severe maternal morbidity (defined as major obstetric haemorrhage, severe hypertensive disorder or high dependency unit/intensive care unit admission) on their post-natal health and other important outcomes including infant feeding. Results indicated that among women who responded (n = 1824, response rate = 53%), there were no statistically significant differences in breastfeeding outcomes between women who did or did not experience severe morbidity, except for women with severe hypertensive disorder who were less likely to breastfeed either partially or exclusively at 6 to 8 weeks post-partum. Rather, breastfeeding outcomes were related to multi-dimensional factors including sociodemographic (age, ethnicity, living arrangement), other pregnancy outcomes (neonatal intensive care unit admission, mode of birth, women's perceived control during birth) and post-natal psychological factors (depressive symptoms). Women who experience severe maternal morbidity can be reassured that establishing successful breastfeeding can be achieved. More studies are required to understand what support is best for women who have complex health/social needs to establish breastfeeding. © 2015 John Wiley & Sons Ltd.

Background Linkages between intrauterine exposures to cocaine and marijuana and adolescents’ problematic substance use have not been fully delineated. Methods Prospective longitudinal study with assessors unaware of intrauterine exposure history followed 157 urban participants from birth until late adolescence. Level of intrauterine exposures was identified by mother's report and infant’s meconium. Problematic substance use, identified by the Voice Diagnostic Interview Schedule for Children (V-DISC) or the Audio Computer Assisted Self-Interview (ACASI) and urine assay, was a composite encompassing DSM-IV indication of tolerance, abuse, and dependence on alcohol, marijuana, and tobacco and any use of cocaine, glue, or opiates. Results Twenty percent (32/157) of the sample experienced problematic substance use by age 18 years, of whom the majority (22/157) acknowledged abuse, tolerance or dependence on marijuana with or without other substances. Structural equation models examining direct and indirect pathways linking a Cox survival model for early substance initiation to a logistic regression models found effects of post-natal factors including childhood exposure to violence and household substance use, early youth substance initiation, and ongoing youth violence exposure contributing to adolescent problematic substance use. Conclusion We did not identify direct relationships between intrauterine cocaine or marijuana exposure and problematic substance use, but did find potentially modifiable post-natal risk factors also noted to be associated with problematic substance use in the general population including earlier substance initiation, exposure to violence and to household substance use.

The growing appreciation of the multi-faceted importance of optimal maternal nutrition to the health and development of the infant and young child is tempered by incompletely resolved strategies for combatting challenges. To review the importance of maternal nutrition and strategies being employed to optimize outcomes. Selected data from recent literature with special focus on rationale for and currently published results of maternal nutrition supplements, including lipid based nutrition supplements. 1) An impelling rationale for improving the maternal and in utero environment of low resource populations has emerged to achieve improved fetal and post-natal growth and development. 2) Based partly on population increases in adult height over one-two generations, much can be achieved by reducing poverty. 3) Maternal, newborn and infant characteristics associated with low resource environments include evidence of undernutrition, manifested by underweight and impaired linear growth. 4) Apart from broad public health and educational initiatives, to date, most specific efforts to improve fetal growth and development have included maternal nutrition interventions during gestation. 5) The relatively limited but real benefits of both iron/folic acid (IFA) and multiple micronutrient (MMN) maternal supplements during gestation have now been reasonably defined. 6) Recent investigations of a maternal lipid-based primarily micronutrient supplement (LNS) have not demonstrated a consistent benefit beyond MMN alone. 7) However, effects of both MMN and LNS appear to be enhanced by commencing early in gestation. Poor maternal nutritional status is one of a very few specific factors in the human that not only contributes to impaired fetal and early post-natal growth but for which maternal interventions have demonstrated improved in utero development, documented primarily by both improvements in low birth weights and by partial corrections of impaired birth length.

This systematic review and meta-analysis reports the efficacy of post-natal physical activity change interventions with content coding of behaviour change techniques (BCTs). Electronic databases (MEDLINE, CINAHL and PsychINFO) were searched for interventions published from January 1980 to July 2013. Inclusion criteria were: (i) interventions including ≥1 BCT designed to change physical activity behaviour, (ii) studies reporting ≥1 physical activity outcome, (iii) interventions commencing later than four weeks after childbirth and (iv) studies including participants who had given birth within the last year. Controlled trials were included in the meta-analysis. Interventions were coded using the 40-item Coventry, Aberdeen & London - Refined (CALO-RE) taxonomy of BCTs and study quality assessment was conducted using Cochrane criteria. Twenty studies were included in the review (meta-analysis: n = 14). Seven were interventions conducted with healthy inactive post-natal women. Nine were post-natal weight management studies. Two studies included women with post-natal depression. Two studies focused on improving general well-being. Studies in healthy populations but not for weight management successfully changed physical activity. Interventions increased frequency but not volume of physical activity or walking behaviour. Efficacious interventions always included the BCTs 'goal setting (behaviour)' and 'prompt self-monitoring of behaviour'.

The aim of this study was to examine infant feeding and the long-chain polyunsaturated fatty acid (LCPUFA) concentration of breast milk and formulas in relation to infant development. The prospective Pregnancy, Infection and Nutrition Study (n=358) collected data on breastfeeding, breast milk samples and the formulas fed through 4months post-partum. At 12months of age, infants' development was assessed (Mullen Scales of Early Learning). Linear regression was used to examine development in relation to breastfeeding, breast milk docosahexaenoic acid (DHA) and arachidonic acid (AA) concentration, and DHA and AA concentration from the combination of breast milk and formula. The median breast milk DHA concentration was 0.20% of total fatty acids [interquartile range (IQR)=0.14, 0.34]; median AA concentration was 0.52% (IQR=0.44, 0.63). Upon adjustment for preterm birth, sex, smoking, race and ethnicity and education, breastfeeding exclusivity was unrelated to development. Among infants exclusively breastfed, breast milk LCPUFA concentration was not associated with development (Mullen composite, DHA: adjusted β=-1.3, 95% confidence interval: -10.3, 7.7). Variables combining DHA and AA concentrations from breast milk and formula, weighted by their contribution to diet, were unassociated with development. We found no evidence of enhanced infant development related to the LCPUFA content of breast milk or formula consumed during the first four post-natal months. © 2011 Blackwell Publishing Ltd.

This study investigated the relationships between pre- and early post-natal maternal depression and their changes with frontal electroencephalogram (EEG) activity and functional connectivity in 6- and 18-month olds, as well as externalizing and internalizing behaviors in 24-month olds (n = 258). Neither prenatal nor postnatal maternal depressive symptoms independently predicted neither the frontal EEG activity nor functional connectivity in 6- and 18-month infants. However, increasing maternal depressive symptoms from the prenatal to postnatal period predicted greater right frontal activity and relative right frontal asymmetry amongst 6-month infants but these finding were not observed amongst 18-month infants after adjusted for post-conceptual age on the EEG visit day. Subsequently increasing maternal depressive symptoms from the prenatal to postnatal period predicted lower right frontal connectivity within 18-month infants but not among 6-month infants after controlling for post-conceptual age on the EEG visit day. These findings were observed in the full sample and the female sample but not in the male sample. Moreover, both prenatal and early postnatal maternal depressive symptoms independently predicted children’s externalizing and internalizing behaviors at 24 months of age. This suggests that the altered frontal functional connectivity in infants born to mothers whose depressive symptomatology increases in the early postnatal period compared to that during pregnancy may reflect a neural basis for the familial transmission of phenotypes associated with mood disorders, particularly in girls.

Head circumference was similar between the two groups at all ages. Longitudinal analyses showed that both post-natal weight (P = 0.005) and height (P = 0.031) differed between the groups throughout the first 2 years of life, while the growth velocity was not significantly different between the two groups. Factors that might influence post-natal growth were included in the analysis; however, it was not possible to include all such factors, for example childhood diseases or nutrition, as this information was not available. The effect of culture medium during the first few days after fertilization on prenatal growth and birthweight persists during the first 2 years of life. This suggests that the human embryo is sensitive to its very early environment, and that the culture medium used in IVF may have lasting consequences. Further monitoring of the long-term growth, development and health of IVF children is therefore warranted. W.V. was funded with an unrestricted research grant from the Stichting Fertility Foundation.

Lack of access to nutritious and balanced diets remains a major impediment to the health and well-being of people living in rural areas. The study utilizes a qualitative systematic approach to conduct an environmental scan and review of scientific literature of studies conducted in South Africa, specifically KwaZulu-Natal (KZN). Availability and access to nutritious, diverse and balanced diets were identified as key constraints for achieving food and nutrition security as well as for human health and well-being. This has led to both under- and over-nutrition, with the former, in particular stunting, affecting children under 5 years. A high incidence of over-nutrition, both overweight and obesity, was observed among black African females. In South Africa, poor people rely mostly on social grants and cannot afford a balanced diet. Under these circumstances, agriculture could be used to increase availability and access to diverse and nutritious foods for the attainment of a balanced diet. The wider use of traditional vegetable crops and pulses could improve availability and access to healthy and locally available alternatives. The promotion of household and community food gardens, and the use of nutrient dense crops with low levels of water use, i.e., high nutritional water productivity, offers prospects for addressing malnutrition in poor rural areas.

Melatonin administered during adulthood induces beneficial effects on cognition and neuroprotection in the Ts65Dn (TS) mouse model of Down syndrome. Here, we investigated the effects of pre- and post-natal melatonin treatment on behavioral and cognitive abnormalities and on several neuromorphological alterations (hypocellularity, neurogenesis impairment and increased oxidative stress) that appear during the early developmental stages in TS mice. Pregnant TS females were orally treated with melatonin or vehicle from the time of conception until the weaning of the offspring, and the pups continued to receive the treatment from weaning until the age of 5 months. Melatonin administered during the pre- and post-natal periods did not improve the cognitive impairment of TS mice as measured by the Morris Water maze or fear conditioning tests. Histological alterations, such as decreased proliferation (Ki67+ cells) and hippocampal hypocellularity (DAPI+ cells), which are typical in TS mice, were not prevented by melatonin. However, melatonin partially regulated brain oxidative stress by modulating the activity of the primary antioxidant enzymes (superoxide dismutase in the cortex and catalase in the cortex and hippocampus) and slightly decreasing the levels of lipid peroxidation in the hippocampus of TS mice. These results show the inability of melatonin to prevent cognitive impairment in TS mice when it is administered at pre- and post-natal stages. Additionally, our findings suggest that to induce pro-cognitive effects in TS mice during the early stages of development, in addition to attenuating oxidative stress, therapies should aim to improve other altered processes, such as hippocampal neurogenesis and/or hypocellularity.

Promoting equity through integrated early child development and nutrition interventions.

Black, Maureen M; Dewey, Kathryn G

2014-01-01

Sustainable development, a foundation of the post-2015 global agenda, depends on healthy and productive citizens. The origins of adult health begin early in life, stemming from genetic-environmental interactions that include adequate nutrition and opportunities for responsive learning. Inequities associated with inadequate nutrition and early learning opportunities can undermine children's health and development, thereby compromising their productivity and societal contributions. Transactional theory serves as a useful framework for examining the associations that link early child development and nutrition because it emphasizes the interplay that occurs between children and the environment, mediated through caregiver interactions. Although single interventions targeting early child development or nutrition can be effective, there is limited evidence on the development, implementation, evaluation, and scaling up of integrated interventions. This manuscript introduces a special edition of papers on six topics central to integrated child development/nutrition interventions: (1) review of integrated interventions; (2) methods and topics in designing integrated interventions; (3) economic considerations related to integrated interventions; (4) capacity-building considerations; (5) examples of integrated interventions; and (6) policy implications of integrated interventions. Ensuring the health and development of infants and young children through integrated child development/nutrition interventions promotes equity, a critical component of sustainable development. © 2014 New York Academy of Sciences.

Accurate nutrient composition data for composite dishes unique to a population is essential for the development of a nutrient database and the calculation of dietary intake. The present study aimed to provide the nutritional composition of composite dishes frequently consumed in rural KwaZulu-Natal, South Africa. Commonly consumed composite dishes were identified using 24-h recalls collected from 79 randomly selected community members. Multiple recipes were collected for each reported dish. The mean nutritional composition of each dish was calculated per 100 g using the nutribase clinical nutrition manager (Cybersoft Inc., Phoenix, AZ, USA). A total of 79 recipes were collected for 16 commonly consumed dishes (seven meat-based, five starch-based and four legume/vegetable-based). 'Fried chicken' contained the most energy [1469 kJ (351 kcal)], protein (29.7 g), fat (23.7 g), cholesterol (123 mg) and niacin (8.4 mg). 'Fried beef' contained the most potassium (495 mg) and zinc (6.4 mg), whereas 'fish stew' had the most vitamin D (4.2 μg) and calcium (215 mg). 'Fried cabbage' and 'fried spinach' contained the largest percent energies from fat, at 79% and 76%, respectively. A traditional sweet bread, 'jeqe', made with fortified flour contributed significantly to iron (4.6 mg), niacin (4.5 μg) and folate (129 μg). The sodium content of dishes ranged from 88 to 679 mg per 100 g. The nutritional composition data for commonly consumed dishes in rural KwaZulu-Natal is presented. Although the dishes are good sources of protein, vitamins and minerals, they also contain substantial amounts of fat. This culturally appropriate information will enable the calculation of dietary intake and can be used to encourage the consumption of recipes rich in key nutrients. © 2012 The Authors Journal of Human Nutrition and Dietetics © 2012 The British Dietetic Association Ltd.

A low glycaemic index (LGI) diet during pregnancy complicated by gestational diabetes mellitus (GDM) may offer benefits to the mother and infant pair beyond those during pregnancy. We aimed to investigate the effect of an LGI diet during pregnancy complicated with GDM on early post-natal outcomes. Fifty-eight women (age: 23-41 years; mean ± SD pre-pregnancy body mass index: 24.5 ± 5.6 kg m(-2) ) who had GDM and followed either an LGI diet (n = 33) or a conventional high-fibre diet (HF; n = 25) during pregnancy had a 75-g oral glucose tolerance test and blood lipid tests at 3 months post-partum. Anthropometric assessments were conducted for 55 mother-infant pairs. The glycaemic index of the antenatal diets differed modestly (mean ± SD: 46.8 ± 5.4 vs. 52.4 ± 4.4; P < 0.001), but there were no significant differences in any of the post-natal outcomes. In conclusion, an LGI diet during pregnancy complicated by GDM has outcomes similar to those of a conventional healthy diet. Adequately powered studies should explore the potential beneficial effects of LGI diet on risk factors for chronic disease. © 2013 John Wiley & Sons Ltd.

A range of important early-life predictors of later obesity have been identified. Children of lower socioeconomic position (SEP) have a steeper weight gain trajectory from birth with a strong socioeconomic gradient in child and adult obesity prevalence. An assessment of the association between SEP and the early-life predictors of obesity has been lacking. The review involved a two-stage process: Part 1, using previously published systematic reviews, we developed a list of the potentially modifiable determinants of obesity observable in the pre-natal, peri-natal or post-natal (pre-school) periods; and part 2, conducting a literature review of evidence for socioeconomic patterning in the determinants identified in part 1. Strong evidence was found for an inverse relationship between SEP and (1) pre-natal risk factors (pre-pregnancy maternal body mass index (BMI), diabetes and pre-pregnancy diet), (2) antenatal/peri natal risk factors (smoking during pregnancy and low birth weight) and (3) early-life nutrition (including breastfeeding initiation and duration, early introduction of solids, maternal and infant diet quality, and some aspects of the home food environment), and television viewing in young children. Less strong evidence (because of a lack of studies for some factors) was found for paternal BMI, maternal weight gain during pregnancy, child sleep duration, high birth weight and lack of physical activity in young children. A strong socioeconomic gradient exists for the majority of the early-life predictors of obesity suggesting that the die is cast very early in life (even pre-conception). Lifestyle interventions targeting disadvantaged women at or before child-bearing age may therefore be particularly important in reducing inequality. Given the likely challenges of reaching this target population, it may be that during pregnancy and their child's early years are more feasible windows for engagement.

Cyp1b1 deletion and gestational vitamin A deficiency (GVAD) redirect adult liver gene expression. A matched sufficient pre- and post-natal diet, which has high carbohydrate and normal iron content (LF12), increased inflammatory gene expression markers in adult livers that were suppressed by GVAD and Cyp1b1 deletion. At birth on the LF12 diet, Cyp1b1 deletion and GVAD each suppress liver expression of the iron suppressor, hepcidin (Hepc), while increasing stellate cell activation markers and suppressing post-natal increases in lipogenesis. Hepc was less suppressed in Cyp1b1−/− pups with a standard breeder diet, but was restored by iron supplementation of the LF12 diet. Conclusions The LF12 diet delivered low post-natal iron and attenuated Hepc. Hepc decreases in Cyp1b1−/− and GVAD mice resulted in stellate activation and lipogenesis suppression. Endothelial BMP6, a Hepc stimulant, is a potential coordinator and Cyp1b1 target. These neonatal changes in Cyp1b1−/− mice link to diminished adult obesity and liver inflammation. PMID:28583802

On account of many literature reports about the definite correlation between high animal protein intake and cardiovascular diseases, we have studied the effect of a hyperproteic purified diet (casein 40%, lactalbumin 20%) on fetal and post-natal (not further than 40th day) stage of the rat, when cell subdivision process is faster and therefore damage by nutritional imbalance is certainly more serious. Litters of rats were grouped according to mother's (either hyperproteic or common basic) and rat's (after lactation) diet. Brain DNA and histology of various organs were studied. Hyperproteic diet during fetal stage and lactation would inhibit brain cell subdivision since overall content of brain DNA would be decreased on autoptic finding. Structural changes were also shown in liver, heart, kidney and adrenal cortex, especially when hyperproteic diet was continued even after lactation.

Interleukin-6 Regulates Adult Neural Stem Cell Numbers during Normal and Abnormal Post-natal Development.

Circulating systemic factors can regulate adult neural stem cell (NSC) biology, but the identity of these circulating cues is still being defined. Here, we have focused on the cytokine interleukin-6 (IL-6), since increased circulating levels of IL-6 are associated with neural pathologies such as autism and bipolar disorder. We show that IL-6 promotes proliferation of post-natal murine forebrain NSCs and that, when the IL-6 receptor is inducibly knocked out in post-natal or adult neural precursors, this causes a long-term decrease in forebrain NSCs. Moreover, a transient circulating surge of IL-6 in perinatal or adult mice causes an acute increase in neural precursor proliferation followed by long-term depletion of adult NSC pools. Thus, IL-6 signaling is both necessary and sufficient for adult NSC self-renewal, and acute perturbations in circulating IL-6, as observed in many pathological situations, have long-lasting effects on the size of adult NSC pools.

Little is known about risk factors for Tourette syndrome (TS) and chronic tic disorders (CT) but maternal psychological morbidity in pregnancy may be associated with TS/CT. We examined whether pre- and post-natal parental anxiety and/or depression are associated with risk of TS/CT in the Avon Longitudinal Study of Parents and Children. We compared self-reported anxiety and depression measures collected prospectively at four time points (18 and 32 weeks prenatally, and 8 weeks and 8 months post-natally) among parents of children who subsequently met criteria for TS/CT at 13 years of age as compared to other children from the cohort. We adjusted for various socioeconomic measures and tested both for time period-specific exposure and chronic exposure using multivariable logistic regression models. 122 children had TS/CT (50 TS, 72 CT) and 5968 children had no tics. In crude analyses, both pre- and post-natal maternal anxiety and depression, but only post-natal paternal depression at 8 months, showed associations with TS/CT. In the final, adjusted multivariable models, chronic maternal anxiety (odds ratio 2.17, 95% CI 1.23, 3.84, p = 0.007) and pre-natal maternal depression (odds ratio 1.86, 95% CI 1.02, 3.39, p = 0.04) showed associations with TS/CT though the latter was consistent with chance (p = 0.07) after adjustment for past maternal depression. We find associations between maternal psychological morbidity pre- and post-natally and risk of future TS/CT in offspring. These associations may reflect either shared genetic susceptibility or a pre-natal exposure. Further work is required to see if these findings can be replicated in larger datasets.

Germline deletion of FAK-related non-kinase delays post-natal cardiomyocyte mitotic arrest

The cardiomyocyte phenotypic switch from a proliferative to terminally differentiated state impacts normal heart development and pathologic myocardial remodeling, yet the signaling mechanisms that regulate this vital process are incompletely understood. Studies from our lab and others indicate that focal adhesion kinase (FAK) is a critical regulator of cardiac growth and remodeling and we found that expression of the endogenous FAK inhibitor, FAK-related non kinase (FRNK) coincided with postnatal cardiomyocyte arrest. Mis-expression of FRNK in the embryonic heart led to pre-term lethality associated with reduced cardiomyocyte proliferation and led us to speculate that the postnatal FRNK surge might be required to promote quiescence in this growth promoting environment. Herein, we provide strong evidence that endogenous FRNK contributes to post-mitotic arrest. Depletion of FRNK promoted DNA synthesis in post-natal day (P) 10 hearts accompanied by a transient increase in DNA content and multi-nucleation by P14, indicative of DNA replication without cell division. Interestingly, a reduction in tri- and tetra-nucleated cardiomyocytes, concomitant with an increase in bi-nucleated cells by P21, indicated the possibility that FRNK-depleted cardiomyocytes underwent eventual cytokinesis. In support of this conclusion, Aurora B-labeled central spindles (a hallmark of cytokinesis) were observed in tetra-nucleated P20 FRNK−/− but not wt cardiomyocytes, while no evidence of apoptosis was observed. Moreover, hearts from FRNK null mice developed ventricular enlargement that persisted until young adulthood which resulted from myocyte expansion rather than myocyte hypertrophy or interstitial growth. These data indicate that endogenous FRNK serves an important role in limiting DNA synthesis and regulating the un-coupling between DNA synthesis and cytokinesis in the post-natal myocardium.

Diet guidelines provided for bariatric surgery patients generally focus on a progression through dietary stages, from the immediate post-surgical period to 6 months after surgery. However, long-term dietary guidelines for those surgically treated for obesity are not readily available. Therefore, there is a need for dietary recommendations for meal planning and nutritional supplementation for bariatric surgery patients beyond the short-term, post-operative period. The purpose of this paper is to construct an educational tool to provide long-term nutritional and behavioral advice for the post-bariatric patient. The manuscript summarizes the current knowledge on dietary strategies and behaviors associated with beneficial nutritional outcomes in the long term of post-bariatric surgery patients. Dietary and nutritional recommendations are presented in the form of a "bariatric food pyramid" designed to be easily disseminated to patients. The development of educational tools that are easy to understand and follow is essential for effective patient management during the surgery follow-up period. The pyramid can be used as a tool to help both therapists and patients to understand nutrition recommendations and thus promote a healthy long-term post-op dietary pattern based on high-quality protein, balanced with nutrient-dense complex carbohydrates and healthy sources of essential fatty acids.

Malnutrition and its associated complications are a considerable issue for surgical patients with upper gastrointestinal and colorectal cancer. The present study aimed to determine whether specific perioperative nutritional practices and protocols are associated with improved patient outcomes in this group. Patients admitted for elective upper gastrointestinal or colorectal cancer surgery (n = 95) over a 19-month period underwent a medical history audit assessing weight changes, nutritional intake, biochemistry, post-operative complications and length of stay. A subset of patients (n = 25) underwent nutritional assessment by subjective global assessment prior to surgery in addition to assessment of post-operative medical outcomes, nutritional intake and timing of dietetic intervention. Mean (SD) length of stay for patients was 14.0 (12.2) days, with complication rates at 35%. Length of stay was significantly longer in patients who experienced significant preoperative weight loss compared to those who did not [17.0 (15.8) days versus 10.0 (6.8) days, respectively; P < 0.05]. Low albumin and post-operative weight loss were also predictive of increased length of stay. Of patients who underwent nutritional assessment, 32% were classified as mild-moderately malnourished and 16% severely malnourished. Malnourished patients were hospitalised twice as long as well-nourished patients [15.8 (12.8) days versus 7.6 (3.5) days; P < 0.05]. Time taken [6.9 (3.6) days] to achieve adequate nutrition post surgery was a factor in post-operative outcomes, with a positive correlation with length of stay (r = 0.493; P < 0.01), a negative correlation with post-operative weight change (r = -0.417; P < 0.05) and a greater risk of complications (52% versus 13%; P < 0.01). Malnutrition is prevalent among surgical patients with gastrointestinal cancer. Poor nutritional status coupled with delayed and inadequate post-operative nutrition practices are associated with worse clinical outcomes.

In this study, fifteen wild boar piglets were intranasally inoculated <10 h after birth with the moderately virulent classical swine fever virus (CSFV) strain Catalonia 01. At 5 days post-inoculation, seven other animals within 48 h of birth were put in contact with them. Viral replication and innate and specific immune responses were evaluated. Of the inoculated animals, 46.67% remained post-natally persistently infected and were apparently healthy with neither humoral nor cellular immunological responses specific to CSFV and with high viral loads in their blood, organs and body secretions. Moreover, the present data extend the time period to 48 h after birth when a moderately virulent CSFV strain could lead to post-natal persistent infection given the generation of persistently infected wild boars in the contact group (33.33%). The innate immune response to the virus, as measured by type I IFN-α in serum, was mostly not impaired in the persistently infected wild boars. Interestingly, a decrease and lack of IFN-γ-producing cells against CSFV and PHA was observed. In endemic countries where wild swine species are increasing and low and moderate virulence CSFV strains are prevalent, the possible generation of this form of disease cannot be ruled out. © 2015 Blackwell Verlag GmbH.

To analyse the reasons underlying the failure of routine pre-natal ultrasonography to prevent the subsequent development of urinary tract infection (UTI) in children with predisposing urological abnormalities. This retrospective study comprised 39 children (22 females and 17 males) who had at least one documented UTI, the presence of an anatomical anomaly of the urinary tract recognized as predisposing to UTI and had undergone ultrasonography of the urinary tract undertaken in fetal life as part of routine maternal ante-natal ultrasonography. Four categories of patients were defined: Group A, those with normal findings on pre-natal ultrasonography and no urological abnormality detected; Group B, those with a urological abnormality detected but where there was a subsequent failure of communication among clinicians; Group C, those with a urological abnormality but who received inappropriate or sub-optimal post-natal management and; Group D, those with a urological abnormality but who had a UTI despite appropriate post-natal management. In each case, the most severe documented episode of UTI was categorized as: Grade I, asymptomatic bacteriuria; Grade II, mild/moderate symptomatic UTI and; Grade III, severe symptomatic UTI necessitating hospital admission. Group A comprised 22 (56%), Group B three (9%), Group C two (5%) and Group D 12 children (31%). Of the 22 children in Group A, nine experienced a UTI of sufficient severity to necessitate hospital admission. Of the 12 children in Group D only one required hospital admission. The failure of pre-natal ultrasonography to identify the underlying predisposing urological abnormality was the most important factor contributing to subsequent UTI in post-natal life. Failure of communication and inappropriate post-natal management were numerically unimportant. In some children, UTI occurred despite pre-natal detection of their underlying anomaly and appropriate post-natal management. However, in this group the UTI was less

In equids, placentation is diffuse and nutrient supply to the fetus is determined by uterine size. This correlates with maternal size and affects intra-uterine development and subsequent post-natal growth, as well as insulin sensitivity in the newborn. Long-term effects remain to be described. In this study, fetal growth was enhanced or restricted through ET using pony (P), saddlebred (S) and draft (D) horses. Control P-P (n = 21) and S-S (n = 28) pregnancies were obtained by AI. Enhanced and restricted pregnancies were obtained by transferring P or S embryos into D mares (P-D, n = 6 and S-D, n = 8) or S embryos into P mares (S-P, n = 6), respectively. Control and experimental foals were raised by their dams and recipient mothers, respectively. Weight gain, growth hormones and glucose homeostasis were investigated in the foals from birth to weaning. Fetal growth was enhanced in P-D and these foals remained consistently heavier, with reduced T3 concentrations until weaning compared to P-P. P-D had lower fasting glucose from days 30 to 200 and higher insulin secretion than P-P after IVGTT on day 3. Euglycemic clamps in the immediate post-weaning period revealed no difference in insulin sensitivity between P-D and P-P. Fetal growth was restricted in S-P and these foals remained consistently lighter until weaning compared to S-D, with elevated T3 concentrations in the newborn compared to S-S. S-P exhibited higher fasting glycemia than S-S and S-D from days 30 to 200. They had higher maximum increment in plasma glucose than S-D after IVGTT on day 3 and clamps on day 200 demonstrated higher insulin sensitivity compared to S-D. Neither the restricted nor the enhanced fetal environment affected IGF-1 concentrations. Thus, enhanced and restricted fetal and post-natal environments had combined effects that persisted until weaning. They induced different adaptive responses in post-natal glucose metabolism: an early insulin-resistance was induced in

The Proteoglycan 4 (Prg4) product lubricin plays essential roles in boundary lubrication and movement in limb synovial joints, but its roles in temporomandibular joint (TMJ) are unclear. Thus, we characterized the TMJ phenotype in wild-type and Prg4 –/– mouse littermates over age. As early as 2 weeks of age, mutant mice exhibited hyperplasia in the glenoid fossa articular cartilage, articular disc, and synovial membrane. By 1 month of age, there were fewer condylar superficial tenascin-C/Col1-positive cells and more numerous apoptotic condylar apical cells, while chondroprogenitors displayed higher mitotic activity, and Sox9-, Col2-, and ColX-expressing chondrocyte zones were significantly expanded. Mutant subchondral bone contained numerous Catepsin K- expressing osteoclasts at the chondro-osseous junction, increased invasive marrow cavities, and suboptimal subchondral bone. Mutant glenoid fossa, disc, synovial cells, and condyles displayed higher Hyaluronan synthase 2 expression. Mutant discs also lost their characteristic concave shape, exhibited ectopic chondrocyte differentiation, and occasionally adhered to condylar surfaces. A fibrinoid substance of unclear origin often covered the condylar surface. By 6 months of age, mutant condyles displayed osteoarthritic degradation with apical/mid-zone separation. In sum, lubricin exerts multiple essential direct and indirect roles to preserve TMJ structural and cellular integrity over post-natal life. PMID:24834922

Postnatal cytomegalovirus (CMV) infection in the newborn can occur from exposure to maternal cervical secretions during birth, ingestion of breast milk, transfusion of blood products or transmission by body fluids of infected people. Breast milk is the main source of infection, given the high rate of CMV-positive mothers excreting CMV in milk. Freezing reduces the risk of CMV transmission by breastfeeding, although it does not eliminate it completely. Pasteurisation prevents such transmission, but it can alter the immunological properties of breast milk. Postnatal CMV infection is usually asymptomatic, as it normally results from viral reactivation in the mother, and the neonate is born with protective antibodies. However, in the very low birth weight premature infant the amount of transferred antibodies is smaller and a symptomatic infection can occur. Symptomatic post-natal CMV infection in the newborn typically causes hepatitis, neutropenia, thrombocytopenia or sepsis-like syndrome. Pneumonitis and enteritis are less common, but very characteristic. Diagnosis is based on urine virus detection at the time of onset of symptoms. Postnatal CMV infection in the newborn generally resolves spontaneously without antiviral treatment. Ganciclovir should be reserved for severe cases. Unlike congenital CMV disease, post-natal CMV infection in the preterm infant does not seem to be associated with hearing loss or abnormal neuro-development in long term follow-up.

Brain-derived neurotrophic factor (BDNF) and its receptor TrkB play a significant role in the regulation of cell growth, survival and death during central nervous system development. The expression of BDNF and TrkB is affected by noxious insults. Two insults during the early post-natal period that are of interest to our laboratory are exposure to nicotine and to intermittent hypercapnic hypoxia (IHH). Piglet models were used to mimic the conditions associated with the risk factors for the sudden infant death syndrome (SIDS) including post-natal cigarette smoke exposure (nicotine model) and prone sleeping where the infant is subjected to re-breathing of expired gases (IHH model). We aimed to determine the effects of nicotine and IHH, alone or in combination, on pro- and rhBDNF and TrkB expression in the developing piglet brainstem. Four piglet groups were studied, with equal gender ratios in each: control (n=14), nicotine (n=14), IHH (n=10) and nic+IHH (n=14). Applying immunohistochemistry, and studying six nuclei of the caudal medulla, we found that compared to controls, TrkB was the only protein significantly decreased after nicotine and nic+IHH exposure regardless of gender. For pro-BDNF and rhBDNF however, observed changes were more evident in males than females exposed to nicotine and nic+IHH. The implications of these findings are that a prior nicotine exposure makes the developing brainstem susceptible to greater changes in the neurotrophic effects of BDNF and its receptor TrkB in the face of a hypoxic insult, and that the effects are greater in males than females.

Although women with rheumatoid arthritis (RA) face a number of challenges in negotiating the journey to parenthood, no studies have explored the information needs of women with RA in relation to their childbearing years. This study aimed to determine the need for (and preferred mode/s of delivery of) information regarding pregnancy, post-natal care and early parenting among women with RA. Interviews and focus groups were conducted with 27 women with RA who were pregnant in the last 5 years, currently pregnant or planning pregnancy. Verbatim transcripts were analysed using both inductive and deductive approaches. Two validated instruments were used to quantify information needs and preferences: the Educational Needs Assessment Tool (ENAT, range 0-156, higher scores indicate higher educational needs) and the Autonomy Preference Index (API, range 0-100, higher scores indicate stronger preferences). Lack of information about medication safety, access to physical/emotional support services and practical strategies for coping with daily challenges related to parenting were the most prominent of the six key themes identified. Rheumatologists were the primary source for information regarding treatment decisions while arthritis consumer organisations were perceived as critical 'resource hubs'. There was strong preference for information delivered electronically, especially among rural participants. Quantitative outcomes supported the qualitative findings; on average, participants reported high educational needs (mean ENAT score 97.2, SD 30.8) and API scores indicated that desire for information (mean 89.8, SD 5.6) was greater than the need for involvement in treatment decision-making (mean 68.4, SD 8.2). Many women with RA struggle to find adequate information on pregnancy planning, pregnancy and early parenting in relation to their chronic condition, and there is a clear need to develop accessible information that is consumer-focused and evidence-based.

Post-natal changes in MCT1 expression in the forestomach of calves.

The monocarboxylate transporter 1 (MCT1) has been demonstrated to be involved in the transfer of short-chain fatty acids (SCFA) and/or their intraepithelial metabolites from the rumen to the blood. As MCT1 plays a role in SCFA transfer, it is assumed that SCFA are the main substrates influencing its expression. However, there are hints that MCT1 may also be expressed during the early life of the animal when SCFA are not released in the forestomach. To figure out whether MCT1 expression in the forestomach is influenced independently of SCFA during that period, we studied post-natal MCT1 expression immunohistochemically in the epithelia of omasum, atrium ruminis, saccus dorsalis ruminis, saccus ventralis ruminis and reticulum of calves born preterm and at term. The calves were nourished by colostrum or by milk-based formula diet. MCT1 could be found in all the forestomach compartments tested, even in preterm calves. The protein was mainly oriented to the luminal side in the immature epithelium 24 h after birth. Orientation to the blood side of the cells developed during the first 4 days after birth. In the rumen epithelia (but not in the other forestomach compartments tested), orientation of MCT1 to the blood side of the cells was paralleled by an increase in the overall expression rate during the first 4 days after birth. As lactate levels were very high directly after birth, a lactate-dependent substrate induction may have been the underlying mechanism. However, non-specific changes due to general differential processes might also be the cause. Both early upregulation of MCT1 and high blood lactate levels may provide the epithelia with lactate as energy source. © 2013 Blackwell Verlag GmbH.

In South Africa few studies have examined the effects of the overlap of HIV and helminth infections on nutritional status. This cross-sectional study investigated the interaction between HIV and intestinal helminths coinfection with nutritional status among KwaZulu-Natal adults. Participants were recruited from a comprehensive primary health care clinic and stratified based on their HIV, stool parasitology, IgE, and IgG4 results into four groups: the uninfected, HIV infected, helminth infected, and HIV-helminth coinfected groups. The nutritional status was assessed using body mass index, 24-hour food recall, micro-, and macronutrient biochemical markers. Univariate and multivariate multinomial probit regression models were used to assess nutritional factors associated with singly and dually infected groups using the uninfected group as a reference category. Biochemically, the HIV-helminth coinfected group was associated with a significantly higher total protein, higher percentage of transferrin saturation, and significantly lower ferritin. There was no significant association between single or dual infections with HIV and helminths with micro- and macronutrient deficiency; however general obesity and low micronutrient intake patterns, which may indicate a general predisposition to micronutrient and protein-energy deficiency, were observed and may need further investigations.

Early nutritional support and physiotherapy improved long-term self-sufficiency in acutely ill older patients.

An acute disease is regularly associated with inflammation, decreased food intake, and low physical activity; the consequence is loss of muscle mass. However, the restoration of muscle tissue is problematic, especially in older patients. Loss of muscle mass leads to further decrease of physical activity which leads, together with recurring disease, to the progressive muscle mass loss accompanied by loss of self-sufficiency. Early nutrition support and physical activity could reverse this situation. Therefore, the aim of this study was to determine whether an active approach based on early nutritional therapy and exercise would influence the development of sarcopenia and impaired self-sufficiency during acute illness. Two hundred patients >78 y were admitted to a hospital internal medicine department and participated in a prospective, randomized controlled study. The patients were randomized to a control group receiving standard treatment (n = 100) or to an intervention group (n = 100). The intervention consisted of nutritional supplements (600 kcal, 20 g/d protein) added to a standard diet and a simultaneous intensive rehabilitation program. The tolerance of supplements and their influence on spontaneous food intake, self-sufficiency, muscle strength, and body composition were evaluated during the study period. The patients were then regularly monitored for 1 y post-discharge. The provision of nutritional supplements together with early rehabilitation led to increased total energy and protein intake while the intake of standard hospital food was not reduced. The loss of lean body mass and a decrease in self-sufficiency were apparent at discharge from the hospital and 3 mo thereafter in the control group. Nutritional supplementation and the rehabilitation program in the study group prevented these alterations. A positive effect of nutritional intervention and exercise during the hospital stay was apparent at 6 mo post-discharge. The early nutritional intervention

Quantification of healthy and atretic germ cells and follicles in the developing and post-natal ovary of the South American plains vizcacha, Lagostomus maximus: evidence of continuous rise of the germinal reserve.

The female germ line in mammals is subjected to massive cell death that eliminates 60-85% of the germinal reserve by birth and continues from birth to adulthood until the exhaustion of the germinal pool. Germ cell demise occurs mainly through apoptosis by means of a biased expression in favour of pro-apoptotic members of the BCL2 gene family. By contrast, the South American plains vizcacha, Lagostomus maximus, exhibits sustained expression of the anti-apoptotic BCL2 gene throughout gestation and a low incidence of germ cell apoptosis. This led to the proposal that, in the absence of death mechanisms other than apoptosis, the female germ line should increase continuously from foetal life until after birth. In this study, we quantified all healthy germ cells and follicles in the ovaries of L. maximus from early foetal life to day 60 after birth using unbiased stereological methods and detected apoptosis by labelling with TUNEL assay. The healthy germ cell population increased continuously from early-developing ovary reaching a 50 times higher population number by the end of gestation. TUNEL-positive germ cells were <0.5% of the germ cell number, except at mid-gestation (3.62%). Mitotic proliferation, entrance into prophase I stage and primordial follicle formation occurred as overlapping processes from early pregnancy to birth. Germ cell number remained constant in early post-natal life, but a remnant population of non-follicular VASA- and PCNA-positive germ cells still persisted at post-natal day 60. L. maximus is the first mammal so far described in which female germ line develops in the absence of constitutive massive germ cell elimination.

Large randomised controlled trials have shown that early supplemental parenteral nutrition in patients admitted to adult and paediatric intensive care units (PICUs) is harmful. Overdosing of energy with too little protein was suggested as a potential reason for this. This study analysed which macronutrient was associated with harm caused by early supplemental parenteral nutrition in the Paediatric Early versus Late Parenteral Nutrition In Critical Illness (PEPaNIC) randomised trial. Patients in the initial randomised controlled trial were randomly assigned to receive suppplemental parenteral nutrition (PN) within 24 h of PICU admission (early PN) or to receive such PN after 1 week (late PN) when enteral nutrition was insufficient. In this post-randomisation, observational study, doses of glucose, lipids, and aminoacids administered during the first 7 days of PICU stay were expressed as % of reference doses from published clinical guidelines for age and weight. Independent associations between average macronutrient doses up to each of the first 7 days and likelihood of acquiring an infection in the PICU, of earlier live weaning from mechanical ventilation, and of earlier live PICU discharge were investigated using multivariable Cox proportional hazard analyses. The three macronutrients were included in the analysis simultaneously and baseline risk factors were adjusted for. From June 18, 2012, to July 27, 2015, 7519 children aged between newborn and 17 years were assessed for eligibility. 6079 patients were excluded, and 1440 children were randomly assigned to receive either early PN (n=723) or late PN (n=717). With increasing doses of aminoacids, the likelihood of acquiring a new infection was higher (adjusted hazard ratios [HRs] per 10% increase between 1·043-1·134 for days 1-5, p≤0·029), while the likelihood of earlier live weaning from mechanical ventilation was lower (HRs 0·950-0·975 days 3-7, p≤0·045), and the likelihood of earlier live PICU

Recent trials have questioned the benefit of early parenteral nutrition in adults. The effect of early parenteral nutrition on clinical outcomes in critically ill children is unclear. We conducted a multicenter, randomized, controlled trial involving 1440 critically ill children to investigate whether withholding parenteral nutrition for 1 week (i.e., providing late parenteral nutrition) in the pediatric intensive care unit (ICU) is clinically superior to providing early parenteral nutrition. Fluid loading was similar in the two groups. The two primary end points were new infection acquired during the ICU stay and the adjusted duration of ICU dependency, as assessed by the number of days in the ICU and as time to discharge alive from ICU. For the 723 patients receiving early parenteral nutrition, parenteral nutrition was initiated within 24 hours after ICU admission, whereas for the 717 patients receiving late parenteral nutrition, parenteral nutrition was not provided until the morning of the 8th day in the ICU. In both groups, enteral nutrition was attempted early and intravenous micronutrients were provided. Although mortality was similar in the two groups, the percentage of patients with a new infection was 10.7% in the group receiving late parenteral nutrition, as compared with 18.5% in the group receiving early parenteral nutrition (adjusted odds ratio, 0.48; 95% confidence interval [CI], 0.35 to 0.66). The mean (±SE) duration of ICU stay was 6.5±0.4 days in the group receiving late parenteral nutrition, as compared with 9.2±0.8 days in the group receiving early parenteral nutrition; there was also a higher likelihood of an earlier live discharge from the ICU at any time in the late-parenteral-nutrition group (adjusted hazard ratio, 1.23; 95% CI, 1.11 to 1.37). Late parenteral nutrition was associated with a shorter duration of mechanical ventilatory support than was early parenteral nutrition (P=0.001), as well as a smaller proportion of patients

Calcium sources used by post-natal human myoblasts during initial differentiation.

Increases in cytoplasmic Ca(2+) are crucial for inducing the initial steps of myoblast differentiation that ultimately lead to fusion; yet the mechanisms that produce this elevated Ca(2+) have not been fully resolved. For example, it is still unclear whether the increase comes exclusively from membrane Ca(2+) influx or also from Ca(2+) release from internal stores. To address this, we investigated early differentiation of myoblast clones each derived from single post-natal human satellite cells. Initial differentiation was assayed by immunostaining myonuclei for the transcription factor MEF2. When Ca(2+) influx was eliminated by using low external Ca(2+) media, we found that approximately half the clones could still differentiate. Of the clones that required influx of external Ca(2+), most clones used T-type Ca(2+) channels, but others used store-operated channels as influx-generating mechanisms. On the other hand, clones that differentiated in low external Ca(2+) relied on Ca(2+) release from internal stores through IP(3) receptors. Interestingly, by following clones over time, we observed that some switched their preferred Ca(2+) source: clones that initially used calcium release from internal stores to differentiate later required Ca(2+) influx and inversely. In conclusion, we show that human myoblasts can use three alternative mechanisms to increase cytoplasmic Ca(2+) at the onset of the differentiation process: influx through T-types Ca(2+) channels, influx through store operated channels and release from internal stores through IP(3) receptors. In addition, we suggest that, probably because Ca(2+) elevation is essential during initial differentiation, myoblasts may be able to select between these alternate Ca(2+) pathways.

The aim of this longitudinal study was to investigate how the kinematic organization of upper limb movements changes from fetal to post-natal life. By means of off-line kinematical techniques we compared the kinematics of hand-to-mouth and hand-to-eye movements, in the same individuals, during prenatal life and early postnatal life, as well as the kinematics of hand-to-mouth and reaching-toward-object movements in the later age periods. Movements recorded at the 14(th), 18(th) and 22(nd) week of gestation were compared with similar movements recorded in an ecological context at 1, 2, 3, 4, 8, and 12 months after birth. The results indicate a similar kinematic organization depending on movement type (i.e., eye, mouth) for the infants at one month and for the fetuses at 22 weeks of gestation. At two and three months such differential motor planning depending on target is lost and no statistical differences emerge. Hand to eye movements were no longer observed after the fourth month of life, therefore we compared kinematics for hand to mouth with hand to object movements. Results of these analyses revealed differences in the performance of hand to mouth and reaching to object movements in the length of the deceleration phase of the movement, depending on target. Data are discussed in terms of how the passage from intrauterine to extra-uterine environments modifies motor planning. These results provide novel evidence of how different types of upper extremity movements, those directed towards one's own face and those directed to external objects, develop.

Programming by early nutrition: an experimental approach.

Lucas, A

1998-02-01

That events during critical or sensitive periods of development may "program" long-term or life-time structure or function of the organism is well recognized. Evidence for programming by nutrition is established in animals, in whom brief pre- or postnatal nutritional manipulations may program adult size, metabolism, blood lipids, diabetes, blood pressure, obesity, atherosclerosis, learning, behavior and life span. Human epidemiological data link potential markers of early nutrition (size at birth or in infancy) to cardiovascular disease and its risk factors in adulthood. However, these retrospective data cannot prove nutritional cause or underpin health policies. After 16 y, however, of ethical, randomized intervention studies of early nutrition in humans with long-term follow-up to test experimentally the nutritional programming hypothesis, we find that humans, like other species, have sensitive windows for nutrition in terms of later outcomes; for instance, perinatal diet influences neurodevelopment and bone mineralization into mid-childhood. Possible biological mechanisms for storing throughout life the "memory" of early nutritional experience and its expression in adulthood include adaptive changes in gene expression, preferential clonal selection of adapted cells in programmed tissues and programmed differential proliferation of tissue cell types. Animal and human evidence supporting nutritional programming has major potential biological and medical significance.

Obesity is considered a public health problem and has led to advancements in bariatric surgery. Laparoscopic sleeve gastrectomy (LSG) had become the most performed procedure worldwide; however, its consequences on nutritional status in the short and long term are of concern. A retrospective analysis of medical records and bariatric database of patients who underwent LSG from October 2008-September 2015 at Al-Amiri Hospital, Kuwait, was performed. Data regarding nutritional status along with demographic data were collected over a 5-year follow-up period. One thousand seven hundred ninety-three patients comprising of 74% females and 26% males were included. The greatest % total body weight loss (%TBWL) was at 18 months post-LSG (33%), corresponding to a % excess weight loss (%EWL) of 73.8%. With regard to nutritional status, vitamin B1 showed a significant drop at 3-5 years post-op in comparison to pre-op value, but stayed within the normal range throughout the study. Red blood cells count, hemoglobin, and hematocrit also showed a significant drop starting from 6 months post-op until the fifth year of follow-up. On the other hand, vitamins B6 and B12 showed a significant increase at 6 months post-op and decreased afterwards, but did not reach pre-op values. Vitamin D also showed a significant increase throughout the study period from deficient value at the pre-op time, but remained insufficient. Albumin, transferrin, folate, ferritin, iron, and vitamin B2 showed no significant changes at 5 years post-LSG compared to pre-op values. Little is known about the nutritional status and optimal nutritional care plan post-LSG, especially in the longer term. Nutritional deficiencies were prevalent prior and post-LSG. Some of the nutritional parameters improved and even reached the abnormal high level post-LSG. These observations highlight the importance of pre- and post-operative nutritional assessment and tailored supplementation to ensure optimal nutritional status.

The birth of a new family member causes many changes in the way a family functions. Annually some 10% of mothers giving birth suffer from post-natal depression. This depression affects the mother herself, the baby and the functioning of the entire family. The healthcare personnel are faced with an important task in supporting the family in the course of changes occasioned by the birth of a baby. According to earlier studies, families with small children are fairly satisfied with the service provided by the child health clinics. The purpose of the present study was to form a theory of interaction with the public health nurse in the child health clinic when the mother is suffering from post-natal depression from the viewpoint of family. The data for the study were gathered by interviewing nine families (nine mothers and five fathers) where the mother had displayed symptoms of post-natal depression. The data were analysed using continuous comparative analysis of grounded theory. The concepts of the theory emerged as a lack of continuing relationship, a need to be equal partners, a lack of individuality and a lack of family care. The relationships between categories were lack of discussing, lack of being confidential and lack of getting help enough. The core category emerging was lack of holistic cooperation with unique family. In spite of the emphasis placed on family centeredness in the operating principles of the work in child health clinics, its implementation in practical work cannot be taken for granted. Because of the limited resources available to the clinics, it is the experience of depressed mother in particular that they are not treated sufficiently as individuals and that they are subjected to adjudication in the clinics. The parents felt that the personality of the public health nurse was crucial to how they felt about the service they obtained from the clinic.

The effects of pre-natal-, early-life- and indirectly-initiated exposures to protracted maximum adversity on the course of schizophrenia are unknown. To compare the aforementioned Holocaust directly exposed subgroups with an indirectly exposed subgroup on the course of schizophrenia. The study population were: Israeli Jews in-uterus or born in Nazi-occupied or dominated European nations by the end of the persecution of the Jews, who were alive in 1950, and who had a last discharge diagnosis of schizophrenia in the Israel National Psychiatric Case Registry by 2013 (N=4933). The population was disaggregated into subgroups who (1) migrated after WWII and who had (1a) pre-natal (n=584, 11.8%) and (1b) early-life (n=3709, 75.2%) initiated exposures to the maximum adversities of the Holocaust, and (2) indirectly exposed individuals to the Holocaust who migrated before the Nazi-era persecution begun (n=640, 13%). Recurrent event survival analyses were computed to examine the psychiatric re-hospitalization risk of the study subgroups, unadjusted and adjusted for age of onset of the disorder and sex. The pre-natal initiated exposure subgroup had a significantly (p<0.05) greater risk of psychiatric re-hospitalizations for schizophrenia than the other subgroups (unadjusted: HR=3.39, 95% CI 2.95, 3.90; adjusted: HR=2.28, 2.00, 2.60). This result replicated in sensitivity analyses for: Poland-born individuals, the years 1922 and 1935; and followed at least 10 years and to the year 2000. Pre-natal initiated exposure to the maximal adversity of the holocaust constitutes a consistent risk factor for a worse course of schizophrenia, a possible byproduct of neurodevelopment disruptions induced by maternal stress and/or famine and/or infections.

Compare the nutritional vulnerability, risk of malnutrition, nutritional status and quality of life (QoL) between recipients and non-recipients of nutrition care and support (NCS) of HIV-positive adults. In 2009, a household-based cross-sectional study of HIV-positive adults, NCS recipients (n=97) and non-NCS recipients (n=203) from KwaZulu-Natal was conducted. Nutritional vulnerability (socio-economic status; food security; self-reported health status; nutritional knowledge and attitude), risk of malnutrition (nutrition assessment screening tool), anthropometry (body mass index; mid-upper arm circumference; waist-to-hip ratio) and QoL (general health; self-care; physical functioning) were compared between the two groups. Although the result suggests a modest impairment of QoL, NCS recipients were twice as likely to have severe impairment of general health; self-care functioning and QoL. Overweight and obesity were common despite indications of high prevalence of food insecurity, possible-risk of malnutrition and diets predominantly of cereals. NCS recipients were more frequently taking anti-retroviral drugs, receiving social grants, reporting good eating plans and owning kitchen gardens. Non-NCS recipients had been generally sick, reported fatigue, nausea, appetite loss and diarrhoea. NCS recipients were twice as likely to experience oral thrush. Contextual factors such as low dietary diversity and household food insecurity that exacerbates nutritional vulnerability and malnutrition should be considered when providing NCS to fully achieve nutritional recovery and QoL of HIV-positive adults.

Background The aim of this longitudinal study was to investigate how the kinematic organization of upper limb movements changes from fetal to post-natal life. By means of off-line kinematical techniques we compared the kinematics of hand-to-mouth and hand-to-eye movements, in the same individuals, during prenatal life and early postnatal life, as well as the kinematics of hand-to-mouth and reaching-toward-object movements in the later age periods. Methodology/Principal Findings Movements recorded at the 14th, 18th and 22nd week of gestation were compared with similar movements recorded in an ecological context at 1, 2, 3, 4, 8, and 12 months after birth. The results indicate a similar kinematic organization depending on movement type (i.e., eye, mouth) for the infants at one month and for the fetuses at 22 weeks of gestation. At two and three months such differential motor planning depending on target is lost and no statistical differences emerge. Hand to eye movements were no longer observed after the fourth month of life, therefore we compared kinematics for hand to mouth with hand to object movements. Results of these analyses revealed differences in the performance of hand to mouth and reaching to object movements in the length of the deceleration phase of the movement, depending on target. Conclusion/Significance Data are discussed in terms of how the passage from intrauterine to extra-uterine environments modifies motor planning. These results provide novel evidence of how different types of upper extremity movements, those directed towards one’s own face and those directed to external objects, develop. PMID:24324642

Reduced resistance to oxidative stress during reproduction as a cost of early-life stress.

PubMed

Zimmer, Cédric; Spencer, Karen A

2015-05-01

Stress exposure during early-life development can have long-term consequences for a variety of biological functions including oxidative stress. The link between early-life stress and oxidative balance is beginning to be explored and previous studies have focused on this link in adult non-breeding or immature individuals. However, as oxidative stress is considered as the main physiological mechanism underlying the trade-off between self-maintenance and investment in reproduction, it is necessary to look at the consequences of early-life stress on oxidative status during reproduction. Here, we investigated the effects of exposure to pre- and/or post-natal stress on oxidative balance during reproduction under benign or stressful environmental conditions in an avian model species, the Japanese quail. We determined total antioxidant status (TAS), total oxidant status (TOS) and resistance to a free-radical attack in individual exposed to pre-natal stress, post-natal stress or both and in control individuals exposed to none of the stressors. TAS levels decreased over time in all females that reproduced under stressful conditions. TOS decreased between the beginning and the end of reproductive period in pre-natal control females. In all females, resistance to a free-radical attack decreased over the reproductive event but this decrease was more pronounced in females from a pre-natal stress development. Our results suggest that pre-natal stress may be associated with a higher cost of reproduction in terms of oxidative stress. These results also confirm that early-life stress can be associated with both benefits and costs depending of the life-history stage or environmental context. Copyright © 2014 Elsevier Inc.

Recent observational research indicates that immune development may be programmed by nutritional exposures early in life. Such findings require replication from trials specifically designed to assess the impact of nutritional intervention during pregnancy on infant immune development. The current trial seeks to establish: (a) which combination of protein-energy (PE) and multiple-micronutrient (MMN) supplements would be most effective; and (b) the most critical periods for intervention in pregnancy and infancy, for optimal immune development in infancy. The ENID Trial is a 2 x 2 x 2 factorial randomized, partially blind trial to assess whether nutritional supplementation to pregnant women (from < 20 weeks gestation to term) and their infants (from 6 to 12 months of age) can enhance infant immune development. Eligible pregnant women from the West Kiang region of The Gambia (pregnancy dated by ultrasound examination) are randomized on entry to 4 intervention groups (Iron-folate (FeFol = standard care), multiple micronutrients (MMN), protein-energy (PE), PE + MMN). Women are visited at home weekly for supplement administration and morbidity assessment and seen at MRC Keneba at 20 and 30 weeks gestation for a detailed antenatal examination, including ultrasound. At delivery, cord blood and placental samples are collected, with detailed infant anthropometry collected within 72 hours. Infants are visited weekly thereafter for a morbidity questionnaire. From 6 to 12 months of age, infants are further randomized to a lipid-based nutritional supplement, with or without additional MMN. The primary outcome measures of this study are thymic development during infancy, and antibody response to vaccination. Measures of cellular markers of immunity will be made in a selected sub-cohort. Subsidiary studies to the main trial will additionally assess the impact of supplementation on infant growth and development to 24 months of age. The proposed trial is designed to test whether

Increasing evidence from the EU Project EARNEST and many other investigators demonstrates that early nutrition and lifestyle have long-term effects on later health and the risk of common non-communicable diseases (known as 'developmental programming'). Because of the increasing public health importance and the transgenerational nature of the problem, obesity and associated disorders are the focus of the new EU funded project 'EarlyNutrition'. Currently, three key hypotheses have been defined: the fuel mediated 'in utero' hypothesis suggests that intrauterine exposure to an excess of fuels, most notably glucose, causes permanent changes of the fetus that lead to obesity in postnatal life; the accelerated postnatal weight gain hypothesis proposes an association between rapid weight gain in infancy and an increased risk of later obesity and adverse outcomes; and the mismatch hypothesis suggests that experiencing a developmental 'mismatch' between a sub-optimal perinatal and an obesogenic childhood environment is related to a particular predisposition to obesity and corresponding co-morbidities. Using existing cohort studies, ongoing and novel intervention studies and a basic science programme to investigate those key hypotheses, project EarlyNutrition will provide the scientific foundations for evidence-based recommendations for optimal nutrition considering long-term health outcomes, with a focus on obesity and related disorders. Scientific and technical expertise in placental biology, epigenetics and metabolomics will provide understanding at the cellular and molecular level of the relationships between early life nutritional status and the risk of later adiposity. This will help refine strategies for intervention in early life to prevent obesity.

Telomere dynamics in blood cells have been linked to aging in a variety of organisms. However, whether blood telomeres are correlated with telomeres in other parts of the body is not well known, especially during early life when telomere loss is expected to be most rapid. We investigated this question in Franklin's gulls (Leucophaeus pipixcan) by measuring telomere lengths in blood and several other tissues including: heart, liver, and skeletal muscle at the end of embryonic (n=31) and post-natal development (n=20). In late-stage embryos, blood telomeres were significantly positively correlated with heart and skeletal muscle, but not liver telomeres. However, at the end of post-natal development, there were no significant correlations among blood telomeres and telomeres in any other tissues. In late-stage embryos, heart telomeres were significantly longer than blood, liver, and skeletal muscle telomeres, but at the end of post-natal development telomere lengths did not significantly differ among tissues. These results suggest that blood telomere length is not necessarily indicative of other tissues at all stages of development and highlights the importance of understanding any functional consequences of tissue specific telomere dynamics in early life.

Increasing evidence from lifetime experimental studies in animals and observational and experimental studies in human subjects suggests that pre- and postnatal nutrition programme long-term health. However, key unanswered questions remain on the extent of early-life programming in contemporary European populations, relevant nutritional exposures, critical time periods, mechanisms and the effectiveness of interventions to prevent or reverse programming effects. The EARly Nutrition programming - long-term Efficacy and Safety Trials and integrated epidemiological, genetic, animal, consumer and economic research (EARNEST) consortium brings together a multi-disciplinary team of scientists from European research institutions in an integrated programme of work that includes experimental studies in human subjects, modern prospective observational studies and mechanistic animal work including physiological studies, cell-culture models and molecular techniques. Theme 1 tests early nutritional programming of disease in human subjects, measuring disease markers in childhood and early adulthood in nineteen randomised controlled trials of nutritional interventions in pregnancy and infancy. Theme 2 examines associations between early nutrition and later outcomes in large modern European population-based prospective studies, with detailed measures of diet in pregnancy and early life. Theme 3 uses animal, cellular and molecular techniques to study lifetime effects of early nutrition. Biomedical studies are complemented by studies of the social and economic importance of programming (themes 4 and 5), and themes encouraging integration, communication, training and wealth creation. The project aims to: help formulate policies on the composition and testing of infant foods; improve the nutritional value of infant formulas; identify interventions to prevent and reverse adverse early nutritional programming. In addition, it has the potential to develop new products through industrial

Calcium channels in solitary retinal ganglion cells from post-natal rat.

PubMed Central

Karschin, A; Lipton, S A

1989-01-01

1. Calcium currents from identified, post-natal retinal ganglion cell neurones from rat were studied with whole-cell and single-channel patch-clamp techniques. Na+ and K+ currents were suppressed with pharmacological agents, allowing isolation of current carried by either 10 mM-Ca2+ or Ba2- during whole-cell recordings. For cell-attached patch recordings, the recording pipette contained 96-110 mM-BaCl2 while the bath solution consisted of isotonic potassium aspartate in order to zero the neuronal membrane potential. 2. A transient component, present in approximately one-third of the whole-cell recordings resembles closely the T-type calcium current observed previously in other tissues. This component activates at low voltages (-40 to -50 mV from holding potentials negative to -80 mV), inactivates with a time constant of 10-30 ms at 35 degrees C, and is carried equally well by Ba2+ or Ca2+. In single-channel recordings small (8 pS) channels are observed whose aggregate microscopic kinetics correspond well to the macroscopic current obtained during whole-cell measurements. 3. During whole-cell recordings, a more prolonged component activates in all retinal ganglion cells at -40 to -20 mV from a holding potential of -90 mV. This component is substantially larger when equimolar Ba2+ replaces Ca2+ as the charge carrier, and is sensitive to the dihydropyridine agonist Bay K8644 (5 microM) and antagonists nifedipine (1-10 microM) and nimodipine (1-10 microM). Thus, the dihydropyridine pharmacology of this prolonged component resembles that of the L-type calcium current found in dorsal root ganglion neurones and in heart cells. Also reminiscent of the L-current, the prolonged component in this preparation is less inactivated at depolarized holding potentials (-60 to -40 mV) than the transient component. In cell-attached recordings, large (20 pS) channels are observed with activation properties similar to those of the prolonged portion of the whole-cell current. 4. omega

Most of the evidence on early feeding of preterm infants was derived from high income settings, it is equally important to evaluate whether it can be successfully implemented into less resourced settings. This study aimed to compare growth and feeding of preterm infants before and after the introduction of a new aggressive feeding policy in Penang Hospital, a tertiary referral hospital in a middle income country. The new aggressive feeding policy was developed mainly from Cochrane review evidence, using early parenteral and enteral nutrition with standardized breastfeeding counselling aimed at empowering mothers to provide early expressed milk. A total of 80 preterm babies (34 weeks and below) discharged from NICU were included (40 pre- and 40 post-intervention). Pre and post-intervention data were compared. The primary outcome was growth at day 7, 14, 21 and at discharge and secondary outcomes were time to full oral feeding, breastfeeding rates, and adverse events. Complete data were available for all babies to discharge. One baby was discharged prior to day 14 and 10 babies before day 21, so growth data for these babies were unavailable. Baseline data were similar in the two groups. There was no significant weight difference at 7, 14, 21 days and at discharge. More post-intervention babies were breastfed at discharge than pre-intervention babies (21 vs. 8, P=0.005). Nosocomial infection (11 vs. 4, P=0.045), and blood transfusion were significantly lower in the postintervention babies than in the pre-intervention babies (31 vs. 13, P=0.01). The post-intervention babies were more likely to achieve shorter median days (interquartile range) to full oral feeding [11 (6) days vs. 13 (11) days, P=0.058] and with lower number affecting necrotising enterocolitis (0 vs. 5, P=0.055). Early aggressive parenteral nutrition and early provision of mother's milk did not result in improved growth as evidenced by weight gain at discharge. However we found more breastfeeding babies

Early-Life Nutritional Programming of Health and Disease in The Gambia.

Moore, Sophie E

2017-01-01

Exposures during early life are increasingly being recognised as factors that play an important role in the aetiology of chronic non-communicable diseases (NCDs). The "Developmental Origins of Health and Disease" (DOHaD) hypothesis asserts that adverse early-life exposures - most notably unbalanced nutrition - leads to an increased risk for a range of NCDs and that disease risk is highest when there is a "mismatch" between the early- and later-life environments. Thus, the DOHaD hypothesis would predict highest risk in settings undergoing a rapid nutrition transition. We investigated the link between early-life nutritional exposures and long-term health in rural Gambia, West Africa. Using demographic data dating back to the 1940s, the follow-up of randomised controlled trials of nutritional supplementation in pregnancy, and the "experiment of nature" that seasonality in this region provides, we investigated the DOHaD hypothesis in a population with high rates of maternal and infant under-nutrition, a high burden from infectious disease, and an emerging risk of NCDs. Key Messages: Our work in rural Gambia suggests that in populations with high rates of under-nutrition in early life, the immune system may be sensitive to nutritional deficiencies early in life, resulting in a greater susceptibility to infection-related morbidity and mortality. © 2017 S.

The National Early Care and Education Learning Collaboratives (ECELC) project aims to facilitate best practices in nutrition, physical activity, screen time, and breastfeeding support and infant feeding among early care and education (ECE) programs across multiple states. The project uses a train-the-trainer approach with 5, in-person learning-collaborative sessions, technical assistance, and action planning. We describe the longitudinal practice-based evaluation of the project and assess whether ECE programs evaluated (n = 104) sustained changes in policies and practices 1 year after completing the project. The number of best practices increased from pre-assessment to post-assessment (P < .01) but did not change significantly from post-assessment to follow-up assessment. ECELC shows promise as an approach to incorporate professional development and training focused on improving best practices for environment-level child nutrition and physical activity, which is one strategy among many that are warranted for obesity prevention in young children.

Reducing stunting by improving maternal, infant and young child nutrition in regions such as South Asia: evidence, challenges and opportunities

PubMed Central

2016-01-01

Abstract Meeting the high nutrient needs of pregnant and lactating women and their young children in regions such as South Asia is challenging because diets are dominated by staple foods with low nutrient density and poor mineral bioavailability. Gaps in nutritional adequacy in such populations probably date back to the agricultural revolution ~10 000 years ago. Options for improving diets during the first 1000 days include dietary diversification and increased intake of nutrient‐rich foods, improved complementary feeding practices, micronutrient supplements and fortified foods or products specifically designed for these target groups. Evidence from intervention trials indicates that several of these strategies, both prenatal and post‐natal, can have a positive impact on child growth, but results are mixed and a growth response is not always observed. Nutrition interventions, by themselves, may not result in the desired impact if the target population suffers from frequent infection, both clinical and subclinical. Further research is needed to understand the mechanisms underlying both prenatal and post‐natal growth restriction. In the meantime, implementation and rigorous evaluation of integrated interventions that address the multiple causes of stunting is a high priority. These intervention packages should ideally include improved nutrition during both pregnancy and the post‐natal period, prevention and control of prenatal and post‐natal infection and subclinical conditions that restrict growth, care for women and children and stimulation of early child development. In regions such as South Asia, such strategies hold great promise for reducing stunting and enhancing human capital formation. PMID:27187908

Natal location influences movement and survival of a spatially structured population of snail kites

2007-01-01

Despite the accepted importance of the need to better understand how natal location affects movement decisions and survival of animals, robust estimates of movement and survival in relation to the natal location are lacking. Our study focuses on movement and survival related to the natal location of snail kites in Florida and shows that kites, in addition to exhibiting a high level of site tenacity to breeding regions, also exhibit particular attraction to their natal region. More specifically, we found that estimates of movement from post-dispersal regions were greater toward natal regions than toward non-natal regions (differences were significant for three of four regions). We also found that estimates of natal philopatry were greater than estimates of philopatry to non-natal regions (differences were statistically significant for two of four regions). A previous study indicated an effect of natal region on juvenile survival; in this study, we show an effect of natal region on adult survival. Estimates of adult survival varied among kites that were hatched in different regions. Adults experienced mortality rates characteristic of the region occupied at the time when survival was measured, but because there is a greater probability that kites will return to their natal region than to any other regions, their survival was ultimately influenced by their natal region. In most years, kites hatched in southern regions had greater survival probabilities than did kites hatched in northern regions. However, during a multiregional drought, one of the northern regions served as a refuge from drought, and during this perturbation, survival was greater for birds hatched in the north. Our study shows that natal location may be important in influencing the ecological dynamics of kites but also highlights the importance of considering temporal variation in habitat conditions of spatially structured systems when attempting to evaluate the conservation value of habitats.

The consequences of early childbearing on the growth and nutritional status of women in India has not been quantified in previous studies. Our study aimed to fill this gap by analysing the association between early marriage and early childbearing on nutritional status of Indian women, with a focus on Bihar and Andhra Pradesh, the two states accounting for the highest proportion of women marrying and giving first birth before 18 years of age. Our findings revealed that a substantial number of women were married before 18 years and thereby exposed to early pregnancy. Furthermore, a significantly higher proportion of women in the 'thin' category were married before 18 years, both in the Indian sample (33 %, p < 0.001) and in the selected states, Andhra Pradesh (31 %, p < 0.001) and Bihar (43 %, p < 0.001), compared to those women married at higher ages. Similarly, across all our samples women whose first birth was before age 18 years also had a significantly higher probability of being in the 'thin' category across all our samples. This pattern was also observed for associations between early childbirth and anemia levels. We conclude that the net effect of the early age at marriage and age at first birth on nutritional status is significant. Our results underline the need for preventing early marriages and the consequent high adolescent pregnancies in India, particularly in high prevalence states. This will help to improve nutritional status and health care utilisation among women, thereby, prevent maternal and child mortality and thus, achieve the MDGs 4-5.

We evaluated the extent to which providing training and technical assistance to early childcare centre (ECC) directors, faculty and staff in the implementation of evidence-based nutrition strategies improved the nutrition contexts, policies and practices of ECC serving racially and ethnically diverse, low-income children in Broward County, Florida, USA. The nutrition strategies targeted snack and beverage policies and practices, consistent with Caring for Our Children National Standards. We used the nutrition observation and document review portions of the Environment and Policy Assessment and Observation (EPAO) instrument to observe ECC as part of a one-group pre-test/post-test evaluation design. ECC located within areas of high rates of poverty, diabetes, minority representation and unhealthy food index in Broward County, Florida, USA. Eighteen ECC enrolled, mean 112·9 (sd 53·4) children aged 2-5 years; 12·3 (sd 7·2) staff members; and 10·2 (sd 4·6) children per staff member at each centre. We found significant improvements in centres' overall nutrition contexts, as measured by total EPAO nutrition scores (P=0·01). ECC made specific significant gains within written nutrition policies (P=0·03) and nutrition training and education (P=0·01). Our findings support training ECC directors, faculty and staff in evidence-based nutrition strategies to improve the nutrition policies and practices of ECC serving racially and ethnically diverse children from low-income families. The intervention resulted in improvements in some nutrition policies and practices, but not others. There remains a need to further develop the evaluation base involving the effectiveness of policy and practice interventions within ECC serving children in high-need areas.

Zika virus (ZIKV) infection is closely associated in the fetus with microcephaly and in the adults with Guillain-Barré syndrome and even male infertility. It is an urgent international priority to develop a safe and effective vaccine that offers protection to both women of childbearing age and their children. In this study, female immunocompetent BALB/c mice were immunized with a DNA-based vaccine candidate, pVAX1-ZME, expressing the prM/E protein of ZIKV, and the immunogenicity for maternal mice and the post-natal protection for suckling mice were evaluated. It was found that administration with three doses of 50 μg pVAX1-ZME via in vivo electroporation induced robust ZIKV-specific cellular and long-term humoral immune responses with high and sustained neutralizing activity in adult mice. Moreover, using a maternal immunization protocol, neutralizing antibodies provided specific passive protection against ZIKV infection in neonatal mice and effectively inhibited the growth delay. This vaccine candidate is expected to be further evaluated in higher animals, and maternal vaccination shows great promise for protecting both women of childbearing age and their offspring against post-natal ZIKV infection. The vaccinated mothers and ZIKV-challenged pups provide key insight into Zika vaccine evaluation in an available fully immunocompetent animal model. Copyright © 2018 Elsevier Ltd.

The testis is especially sensitive to pollutants, including radionuclides. Following the Chernobyl nuclear power plant accident, several of these radionuclides were emitted and spread in the environment. Subsequently, children presented some disruptions of the endocrine system. To determine whether these disruptions were due to 137 cesium ((137)Cs) exposure, the effects of chronic contamination with low doses of (137)Cs in utero or from birth on testicular steroidogenesis in rats were studied. Contamination was continued for 9 months. No modification was observed in circulating level of hormones (17beta-estradiol, testosterone, follicle-stimulating hormone, luteinizing hormone) following in utero or post-natal contamination. Expression of several genes involved in testicular steroidogenesis was affected (cyp19a1, fxr, sf-1), without modification of protein expression or activity. Our results suggest that growing organisms may be affected at the molecular level by (137)Cs contamination at this post-accidental dose. Copyright 2010 Académie des sciences.

Nutritional status and dietary intake are increasingly recognized as essential areas in esophageal cancer management. Nutritional management of esophageal cancer is a continuously evolving field and comprises an interesting area for scientific research. Areas covered: This review encompasses the current literature on nutrition in the pre-operative, peri-operative, and post-operative phases of esophageal cancer. Both established interventions and potential novel targets for nutritional management are discussed. Expert commentary: To ensure an optimal pre-operative status and to reduce peri-operative complications, it is key to assess nutritional status in all pre-operative esophageal cancer patients and to apply nutritional interventions accordingly. Since esophagectomy results in a permanent anatomical change, a special focus on nutritional strategies is needed in the post-operative phase, including early initiation of enteral feeding, nutritional interventions for post-operative complications, and attention to long-term nutritional intake and status. Nutritional aspects of pre-optimization and peri-operative management should be incorporated in novel Enhanced Recovery After Surgery programs for esophageal cancer.

Update on Early Nutrition and Food Allergy in Children.

Lee, Sun Eun; Kim, Hyeyoung

2016-05-01

With growing evidence of an increase in the prevalence, food allergy has been emerged as a new public health problem. As treatment and management of food allergy remain challenging, more attention has been paid to the importance of prevention of food allergy. Although the exact mechanism of recent epidemic is not fully understood, it is suggested that nutritional exposure in early life may play an important role in food allergy development. The underlying hypothesis is that nutritional status or food exposure in the critical period of fetal development can affect the programming of immune system and modify the risk of immunologic reactions to foods in postnatal life. We review accumulating epidemiological studies to examine an association between nutritional exposure during pregnancy or early infancy and food allergy development in children. We also discuss recent advances in the studies of the genetic and epigenetic regulation of food allergy and evaluate the role of early nutrition in food allergy development to provide a new perspective on the prevention of food allergy.

On the 9 th October 2000, Dr Daksha Emson, a London based psychiatrist with bipolar affective disorder, tragically killed herself and her three-month-old baby daughter during a psychotic episode. An independent inquiry into Dr Emson's death concluded that mental health stigma in the National Health Service was a factor that contributed to her death. Despite the morbidity and mortality attributed to the stigma attached to post-natal mental health problems there are very few programmes that have been developed to challenge it. King's College London Undergraduate Psychiatry Society organized an event entitled, 'A Labour of Love': Perinatal Mental Health to address this issue. The event included a talk from an expert by experience, a mother who developed post-partum mental health problems. We conducted a single-arm, pre-post comparison study on participants who attended the KCL Psych Soc event. Validated stigma scales on knowledge (Mental Health Knowledge Schedule (MAKS)), attitudes (Community Attitudes towards the Mentally Ill (CAMI)) and behaviour (Reported and Intended Behaviour Scale (RIBS)) were administered before and immediately after exposure to the event. 27/27 (100%) of participants recruited responded. There was a statistically significant difference in the pre-MAKS score compared to the post-MAKS score (p=0.0003), the pre-RIBS score compared to the post-RIBS score (p=0.0068) and in the pre-CAMI score compared to the post-CAMI score (p=0.0042). There were statistically significant reductions in stigma in the domains of knowledge, attitude and behavior following exposure to the KCL Psych Soc event and no adverse effects were reported. Our study revealed that a brief intervention made a highly significant impact and maybe useful in challenging the stigma around post-natal mental illness. However, more research in this area is required to determine if the changes are sustained before we can consider rolling out and scaling up such an initiative nationally and

The impact of early enteral nutrition (EEN) on clinical outcomes of gastric cancer patients was investigated. Three hundred pa-tients undergoing gastric cancer surgery from July 2010 to May 2014 were randomly divided into experimental and control groups (n = 150/group). Experimental group patients received enteral nutrition in water during the early postoperative period. Control group patients received conventional perioperative treatment. Patients' clinical outcomes, post-operative immune function, and nutritional statuses were compared, which revealed that the postoperative fever duration (80.2 ± 6.0 vs 88.1 ± 8.1 h, P < 0.05), anal exhaust time (78.8 ± 9.3 vs 85.3 ± 8.4 h, P < 0.05), and length of hospitalization (7.73 ± 2.13 vs 9.77 ± 1.76 days, P < 0.01) differed significantly. Treatment costs in thousands of dol-lars were 31.24 ± 3.21 for the experimental group and 35.61 ± 2.32 for the control group; this difference was statistically significant (P < 0.01). The incidence of postoperative complications did not significantly differ between the experimental and control groups [14.0% (21/150) vs 17.3% (26/150), P > 0.05]. At postoperative days 3 and 7, the CD3(+), CD4(+), natural killer cell, albumin, and prealbumin levels and CD4(+)/CD8(+) ra-tio were significantly higher in the experimental group than the control group (all P < 0.05). CD8(+) cell counts were significantly lower in the experimental group than the control group (P < 0.05). Postsurgical oral EEN can improve nutritional status and immune function and promote early recovery of intestinal function in patients with gastric cancer.

Little is known about post-natal growth in IVF offspring and the effects of rates of early post-natal growth on blood pressure and body fat composition during childhood and adolescence. The follow-up study comprised 233 IVF children aged 8-18 years and 233 spontaneously conceived controls born to subfertile parents. Growth data from birth to 4 years of age, available for 392 children (n = 193 IVF, n = 199 control), were used to study early post-natal growth. Furthermore, early post-natal growth velocity (weight gain) was related to blood pressure and skinfold measurements at follow-up. We found significantly lower weight, height and BMI standard deviation scores (SDSs) at 3 months, and weight SDS at 6 months of age in IVF children compared with controls. Likewise, IVF children demonstrated a greater gain in weight SDS (P < 0.001), height SDS (P = 0.013) and BMI SDS (P = 0.029) during late infancy (3 months to 1 year) versus controls. Weight gain during early childhood (1-3 years) was related to blood pressure in IVF children (P = 0.014 systolic, 0.04 diastolic) but not in controls. Growth during late infancy was not related to skinfold thickness in IVF children, unlike controls (P = 0.002 peripheral sum, 0.003 total sum). Growth during early childhood was related to skinfold thickness in both IVF and controls (P = 0.005 and 0.01 peripheral sum and P = 0.003 and 0.005 total sum, respectively). Late infancy growth velocity of IVF children was significantly higher compared with controls. Nevertheless, early childhood growth instead of infancy growth seemed to predict cardiovascular risk factors in IVF children. Further research is needed to confirm these findings and to follow-up growth and development of IVF children into adulthood.

The benefits of early enteral feeding (EEN) have been demonstrated in gastrointestinal surgery. But, the impact of EEN has not been elucidated yet. We assessed the postoperative nutritional status of patients who had undergone pancreaticoduodenectomy (PD) according to the postoperative nutritional method and compared the clinical outcomes of two methods. A prospective randomized trial was undertaken following PD. Patients were randomly divided into two groups; the EEN group received the postoperative enteral feed and the control group received the postoperative total parenteral nutrition (TPN) management. Thirty-eight patients were included in our analyses. The first day of bowel movement and time to take a normal soft diet was significantly shorter in EEN group than in TPN group. Prealbumin and transferrin were significantly reduced on post-operative day (POD) 7 and were slowly recovered until POD 90 in the TPN group than in the EEN group. EEN group rapidly recovered weight after POD 21 whereas it was gradually decreased in TPN group until POD 90. EEN after PD is associated with preservation of weight compared with TPN and impact on recovery of digestive function after PD. PMID:22379336

To assess the difference between early enteral nutrition (EEN group) and total parenteral nutrition (TPN group) after total gastrectomy for gastric cancer. The nutrition index, liver function, patient generated subjective global assessment (PG-SGA) score, the post-operation complications, the hospital stay and hospitalization expense of the postoperative patient after total gastrectomy, admitted to our Department of Surgery from May 2011 to May 2013 were analyzed retrospectively. A total of 72 patients including 37 cases in the EEN group and 35 cases in the TPN group were recruited. Hypoalbuminemia gradually improved in the EEN group about 3-5 days, but it did not increase until average 21 days in the TPN group. The body weight decreased in the EEN group during the first 2 weeks and recovered gradually in 21 days; body weight in the TPN group was significantly lower than the EEN group at 21 days (p<0.05). There were significant differences in both the groups (p<0.05) in nutrition indicators. The incidence of complications in the EEN group and TPN group were 8.1% and 25.7% respectively, with no significant differences (p>0.05). The days of hospital stays in the EEN and in the TPN group were up to 12.2 ± 2.5 d vs 14.9 ± 2.9 d (p<0.05) and the hospitalization expenses were 36472 ± 4833 CNY vs 40140 ± 3927 CNY (p<0.05), respectively. Compared with TPN, EEN was safe and well tolerated and can shorten the hospital stay as well as reduce costs incurred with total gastrectomy for gastric cancer.

There are limited data regarding the associations of both maternal and paternal anthropometrics with longitudinally measured post-natal growth measures in early childhood. To assess the associations of maternal and paternal anthropometrics with growth characteristics and the risk of overweight in pre-school children. Population-based prospective cohort study from early foetal life onwards in the Netherlands. Maternal pre-pregnancy anthropometrics and gestational weight gain, and paternal anthropometrics were related to foetal and post-natal growth measures and the risk of overweight until the age of 4 years. Analyses were based on 5674 mothers, fathers and their children. Both pre-pregnancy maternal and paternal height, weight and body mass index were associated with corresponding foetal and post-natal anthropometric measures. Maternal body mass index had a significantly stronger effect on childhood body mass index than paternal body mass index. As compared to children from parents with normal body mass index, children from two obese parents had an increased risk of overweight at the age of 4 years (odds ratio 6.52 (95% confidence interval 3.44, 12.38). Maternal gestational weight gain was only among mothers with normal body mass index associated with body mass index and the risk of overweight in the children. Maternal and paternal anthropometrics affect early growth in pre-school children differently. Gestational weight gain in mothers without overweight and obesity is related to the risk of overweight in early childhood. © 2012 The Authors.

Food quality, determined by micronutrient content, is a stronger determinant of nutritional status than food quantity. Health concerns resulting from the co-existence of over-nutrition and under-nutrition in low income populations in South Africa have been fully recognized in the last two decades. This study aimed to further investigate dietary adequacy amongst adults in rural KwaZulu-Natal, by determining daily energy and nutrient intakes, and identifying the degree of satisfaction of dietary requirements. Cross-sectional study assessing dietary adequacy from 24-hour dietary recalls of randomly selected 136 adults in Empangeni, KwaZulu-Natal, South Africa. Results are presented for men (n = 52) and women (n = 84) 19-50 and >50 years old. Mean energy intake was greatest in women >50 years (2852 kcal/day) and exceeded Dietary Reference Intake's for both men and women, regardless of age. Mean daily energy intake from carbohydrates was 69% for men and 67% for women, above the Dietary Reference Intake range of 45-65%. Sodium was also consumed in excess, and the Dietary Reference Intakes of vitamins A, B12, C, D, and E, calcium, zinc and pantothenic acid were not met by the majority of the population. Despite mandatory fortification of staple South African foods, micronutrient inadequacies are evident among adults in rural South African communities. Given the excess caloric intake and the rising prevalence of obesity and other non-communicable diseases in South Africa, a focus on diet quality may be a more effective approach to influence micronutrient status than a focus on diet quantity.

Accompanying the beneficial improvement in litter size from genetic selection for high-prolificacy sows, within-litter variation in birth weight has increased with detrimental effects on post-natal growth and survival due to an increase in the proportion of piglets with low birth-weight. Causes of within-litter variation in birth weight include breed characteristics that affect uterine space, ovulation rate, degree of maturation of oocytes, duration of time required for ovulation, interval between ovulation and fertilization, uterine capacity for implantation and placentation, size and efficiency of placental transport of nutrients, communication between conceptus/fetus and maternal systems, as well as nutritional status and environmental influences during gestation. Because these factors contribute to within-litter variation in birth weight, nutritional status of the sow to improve fetal-placental development must focus on the following three important stages in the reproductive cycle: pre-mating or weaning to estrus, early gestation and late gestation. The goal is to increase the homogeneity of development of oocytes and conceptuses, decrease variations in conceptus development during implantation and placentation, and improve birth weights of newborn piglets. Though some progress has been made in nutritional regulation of within-litter variation in the birth weight of piglets, additional studies, with a focus on and insights into molecular mechanisms of reproductive physiology from the aspects of maternal growth and offspring development, as well as their regulation by nutrients provided to the sow, are urgently needed.

Persistent lingual ulceration (Riga-Fede disease) in an infant with Down syndrome and natal teeth: a case report.

Riga-Fede disease is a rare pediatric condition in which chronic lingual ulceration results from repetitive trauma. Neonatal teeth or underlying neuro-developmental disorders which include Down syndrome are described as causative factors, but to the best of our knowledge, this is the first case report of both Down syndrome and natal teeth coexisting. The need for early extraction in the presence of two risk factors is highlighted in this case report. An 18-month-old Sinhalese male presented with an ulcerating lingual mass on the ventral surface of the tongue. The lesion had progressed over the past six months. He also had clinically diagnosed Down syndrome.The ulcer was non-tender, indurated, and had elevated margins. It was not bleeding and two natal teeth in lower central dentition were seen in apposition with the lesion. There was no regional lymphadenopathy but the ulcer was causing concerns as it mimicked a malignant lesion. A clinical diagnosis of Riga-Fede disease caused by raking movements of the tongue against anterior natal teeth by a child who was developmentally delayed and prone to suck on his tongue was made. The mother was reassured and the natal teeth were extracted. Early extraction of natal teeth is recommended only if there is a risk of aspiration or interference with breast feeding. Although Down syndrome is among the neuro-developmental conditions that lead to this lesion, its occurrence is usually at an older age. The presence of natal teeth together with Down syndrome caused the lesion to occur in infancy. Awareness of the benign nature of this rare condition by pediatricians and dental practitioners is important as it will allay anxiety and avoid unnecessary biopsy. This case also highlights the impact of two risk factors and needs consideration as an added indication for the early extraction of natal teeth.

Very low birth weight (VLBW) preterm infants are vulnerable to growth restriction after discharge due to cumulative protein and energy deficits during their hospital stay and early post-discharge period. The current study evaluated the effectiveness of the preterm infant, post-discharge nutrition (PIN) program to reduce post-discharge growth restriction in Thai VLBW preterm infants. A prospective, non-randomized interventional cohort study was undertaken to assess the growth of 22 VLBW preterm infants who received the PIN program and compared them with 22 VLBW preterm infants who received conventional nutrition services. Infant's growth was recorded monthly until the infants reached six months' corrected age (6-moCA). Intervention infants had significantly greater body weights ( p = 0.013) and head circumferences ( p = 0.009). Also, a greater proportion of the intervention group recovered their weight to the standard weight at 4-moCA ( p = 0.027) and at 6-moCA ( p = 0.007) and their head circumference to the standard head circumference at 6-moCA ( p = 0.004) compared to their historical comparison counterparts. Enlistment in the PIN program thus resulted in significantly reduced post-discharge growth restriction in VLBW preterm infants. Further research on longer term effects of the program on infant's growth and development is warranted.

Different etiologies are related to tinnitus including metabolic disorders (blood glucose and lipids). The aim of this study was compare tinnitus severity by self-report measures pre and post nutritional intervention, using the Tinnitus Handicap Inventory. Participants of this study were twenty one male and female subjects, with ages ranging from 40 to 82 years. Inclusion criteria involved the presence of tinnitus and metabolic disorder diagnosed by laboratory exams. All subjects were submitted to a nutritional intervention program. Audiological evaluation and the Tinnitus Handicap Inventory were applied pre and post intervention. When comparing the presence of tinnitus pre and post intervention, data analysis indicates statistical difference concerning tinnitus sensation--71.5% of the individuals referred less impact of tinnitus in daily activities. An important difference was observed concerning tinnitus influence in subject's life by self-report measures. A direct relation between tinnitus and metabolic disorders in cases related with this symptom was verified.

The prevalence of metabolic syndrome and obesity has been increasing. Pre-natal environment has been suggested as a factor influencing the risk of metabolic syndrome in adulthood. Both observational and experimental studies showed that maternal diet is a major modifier of the development of regulatory systems in the offspring in utero and post-natally. Both protein content and source in maternal diet influence pre- and early post-natal development. High and low protein dams’ diets have detrimental effect on body weight, blood pressure191 and metabolic and intake regulatory systems in the offspring. Moreover, the role of the source of protein in a nutritionally adequate maternal diet in programming of food intake regulatory system, body weight, glucose metabolism and blood pressure in offspring is studied. However, underlying mechanisms are still elusive. The purpose of this review is to examine the current literature related to the role of proteins in maternal diets in development of characteristics of the metabolic syndrome in offspring.

Hypoplasia-associated Severe Early Childhood Caries – A Proposed Definition

PubMed Central

Caufield, P.W.; Li, Y.; Bromage, T.G.

2012-01-01

We propose a new classification of severe early childhood caries (S-ECC): hypoplasia-associated severe early childhood caries (HAS-ECC). This form of caries affects mostly young children living at or below poverty, characterized by structurally damaged primary teeth that are particularly vulnerable to dental caries. These predisposing developmental dental defects are mainly permutations of enamel hypoplasia (EHP). Anthropologists and dental researchers consider EHP an indicator for infant and maternal stresses including malnutrition, a variety of illnesses, and adverse birthing conditions. Differentiation of HAS-ECC from other forms of early childhood caries is warranted because of its distinct etiology, clinical presentation, and eventual management. Defining HAS-ECC has important clinical implications: Therapies that control or prevent other types of caries are likely to be less effective with HAS-ECC because the structural integrity of the teeth is compromised prior to their emergence into the oral cavity. By the time these children present to the dentist, the treatment options often become limited to surgical management under general anesthesia. To prevent HAS-ECC, dentists must partner with other health providers to develop interventions that begin with pregnant mothers, with the aim of eliminating or ameliorating the covariates accompanying poverty, including better pre- and post-natal care and nutrition.

Extensive neuromotor development occurs early in human life, and the timing of brain injury may affect the resulting motor impairment. In Part I of this series, it was demonstrated that the distribution of weakness in the upper extremity depended on the timing of brain injury in individuals with childhood-onset hemiparesis. The goal of this study was to characterize how timing of brain injury affects joint torque synergies, or losses of independent joint control. Twenty-four individuals with hemiparesis were divided into 3 groups based on the timing of their injury: before birth (PRE-natal, n = 8), around the time of birth (PERI-natal, n = 8), and after 6 months of age (POST-natal, n = 8). Individuals with hemiparesis and 8 typically developing peers participated in maximal isometric shoulder, elbow, wrist, and finger torque generation tasks while their efforts were recorded by a multiple degree-of-freedom load cell. Motor output in 4 joints of the upper extremity was concurrently measured during 8 primary torque generation tasks to quantify joint torque synergies. There were a number of significant coupling patterns identified in individuals with hemiparesis that differed from the typically developing group. POST-natal differences were most noted in the coupling of shoulder abductors with elbow, wrist, and finger flexors, while the PRE-natal group demonstrated significant distal joint coupling with elbow flexion. The torque synergies measured provide indirect evidence for the use of bulbospinal pathways in the POST-natal group, while those with earlier injury may use relatively preserved ipsilateral corticospinal motor pathways.

Differences in nutritional experiences during sensitive periods in early life, both before and after birth, can program a person's future development, metabolism, and health. A better scientific understanding of early nutrition programming holds enormous potential for implementing preventive strategies to enhance individuals' long-term health, well-being, and performance. This understanding could reduce costs of health care and social services and may enhance the wealth of societies. The Early Nutrition Programming Project (EARNEST) brought together a multidisciplinary team of international scientists and leaders in key areas of the early nutrition programming field from 40 major research centers across 16 European countries. The project had a total budget of 16.5 million Euros and was funded by the European Communities under the Sixth Framework Program for Research and Technical Development and coordinated by the Children's Hospital at Ludwig-Maximilians-University of Munich. The integrated program of work combined experimental studies in humans, prospective observational studies, and mechanistic animal work, including physiologic studies, cell culture models, and molecular biology techniques. The project lasted from April 2005 to October 2010. After the end of the project, the Early Nutrition Academy (http://www.early-nutrition.org) continues to serve as a platform for the exchange of information, scientific collaboration, and training activities in the area of programming. This article highlights some of the scientific results, achievements, and efforts of EARNEST.

Exposures during the early life (periconceptional, prenatal and early postnatal) period are increasingly recognized as playing an important role in the aetiology of chronic non-communicable diseases (NCD), including coronary heart disease, stroke, hypertension, Type 2 diabetes and osteoporosis. The 'Developmental Origins of Health and Disease' (DOHaD) hypothesis states that these disorders originate through unbalanced nutrition early in life and risk is highest when there is a 'mismatch' between the early- and later-life environments. Thus, the DOHaD hypothesis would predict highest risk in countries where an excess of infants are born with low birth weight and where there is a rapid transition to nutritional adequacy or excess in adulthood. Here, I will review data from work conducted in rural Gambia, West Africa. Using demographic data dating back to the 1940s, the follow-up of randomized controlled trials of nutritional supplementation in pregnancy and the 'experiment of nature' that seasonality in this region provides, we have investigated the DOHaD hypothesis in a population with high rates of maternal and infant under-nutrition, a high burden from infectious disease, and an emerging risk of NCDs.

Too Early Initiation of Enteral Nutrition is Not Nutritionally Advantageous for Comatose Acute Stroke Patients.

Comatose acute stroke patients are at high risk of malnutrition, especially hypoproteinemia. However, when to start and how to provide nutrition to these patients are unclear. The purpose of this study was to determine the optimum timing and methods of nutritional supplementation to comatose acute stroke patients. A total of 273 comatose acute stoke patients who were unable to eat were enrolled. They received peripheral intravenous low-calorie solutions for the first 4 days after admission (days 0-3), and serum protein concentrations were measured on days 2, 3, and 4. From day 4, 5 different nutritional regimens were administered (25 kcal/kg/day), (including enteral nutrition [EN], total parenteral nutrition [TPN], tube feeding of 20% glucose solution, and combinations of these nutritional supplementations),. Serum concentrations of total protein and albumin were measured on days 10, 14, and 21. The patients who had EN until day 21 from day 4 were defined as EN group, and who had TPN were as TPN group. Serum protein concentrations decreased slightly on day 2 and decreased significantly on days 3 and 4. From day 4 to 14, the recovery of serum protein was better in the TPN group than in the EN group. Conversely, after day 14, recovery from hypoproteinemia was better in the EN group than in the TPN group. However, when diarrhea was caused by EN, further hypoproteinemia occurred and caused patients to require TPN. The recovery from hypoproteinemia was earliest in patients receiving TPN with 20% glucose fed through a nasogastric tube from day 4 to 13 followed by EN after day 14. Hospitalization was statistically shorter for patients with a nutritionally early recovery than for patients with a delayed recovery, but clinical outcome did not differ significantly between the groups. It is nutritionally disadvantageous not to start nutritional support within 3 days after admission in comatose acute stroke patients. However, starting EN too early is not nutritionally

Gender dysphoria is a new entity introduced in the Diagnostic and Statistical Manual of Mental Disorder V to address the distress of the previously labeled gender identity disorder patients. It is less commonly seen in natal females, often starting in their childhood. Adults and adolescent natal females with early-onset gender dysphoria are almost always gynephilic. This case report is presented to discuss the interesting evolution of the symptoms in gender dysphoria case with difficulties in adjusting to the assigned sexual role, relationship problems, morbid jealousy, and severe depressive features with suicidal ideations.

The present study was conducted to investigate the clinical efficacy of early parenteral and enteral nutrition (PN + EN) support in neurosurgical coma patients. Eighty cases of neurosurgical coma patients were randomly divided into intervention group and control group. The intervention group received early PN + EN support, and the control group received only total enteral nutritional (TEN) support. The levels of hemoglobin (HGB), serum albumin (ALB), prealbumin (PA), and retinol-binding protein (RBP) in two groups on days 1, 10, and 20 were observed. The incidences of pneumonia, stress ulcer, abnormal liver function, abdominal distension, and diarrhea between two groups were also compared. Results found that, on day 10, compared with the control group, the levels of HGB, PA, and RBP in the intervention group were significantly increased (P < 0.05). On day 20, ALB in the intervention group significantly increased (P < 0.05), and the incidences of pneumonia, abdominal distension, and diarrhea in the intervention group were significantly lower than those in the control group (P < 0.05). Compared with only TEN support, early PN + EN support can obviously improve the nutritional status of neurosurgical coma patients and reduce the occurrence of complications.

Early-life nutritional effects on the female reproductive system.

There is now considerable epidemiological and experimental evidence indicating that early-life environmental conditions, including nutrition, affect subsequent development in later life. These conditions induce highly integrated responses in endocrine-related homeostasis, resulting in persistent changes in the developmental trajectory producing an altered adult phenotype. Early-life events trigger processes that prepare the individual for particular circumstances that are anticipated in the postnatal environment. However, where the intrauterine and postnatal environments differ markedly, such modifications to the developmental trajectory may prove maladaptive in later life. Reproductive maturation and function are similarly influenced by early-life events. This should not be surprising, because the primordial follicle pool is established early in life and is thus vulnerable to early-life events. Results of clinical and experimental studies have indicated that early-life adversity is associated with a decline in ovarian follicular reserve, changes in ovulation rates, and altered age at onset of puberty. However, the underlying mechanisms regulating the relationship between the early-life developmental environment and postnatal reproductive development and function are unclear. This review examines the evidence linking early-life nutrition and effects on the female reproductive system, bringing together clinical observations in humans and experimental data from targeted animal models. © 2015 Society for Endocrinology.

Early Nutrition and Physical Activity Interventions in Childhood Cancer Survivors

Purpose of review Childhood cancer survivors experience excessive weight gain early in treatment. Lifestyle interventions need to be initiated early in cancer care to prevent the early onset of obesity and cardiovascular disease (CVD). We reviewed the existing literature on early lifestyle interventions in childhood cancer survivors and consider implications for clinical care. Recent findings Few lifestyle interventions focus on improving nutrition in childhood cancer survivors. A consistent effect on reducing obesity and CVD risk factors is not evident from the limited number of studies with heterogeneous intervention characteristics, although interventions with a longer duration and follow-up show more promising trends. Summary Future lifestyle interventions should be of a longer duration and include a nutrition component. Interventions with a longer duration and follow-up are needed to assess the timing and sustainability of the intervention effect. Lifestyle interventions introduced early in cancer care are both safe and feasible. PMID:28455678

During development, the risk of developing mesial temporal lobe epilepsy (MTLE) increases when the developing brain is exposed to more than one insult in early life. Early life insults include abnormalities of cortical development, hypoxic-ischemic injury and prolonged febrile seizures. To study epileptogenesis, we have developed a two-hit model of MTLE characterized by two early-life insults: a freeze lesion-induced cortical malformation at post-natal day 1 (P1), and a prolonged hyperthermic seizure (HS) at P10. As early life stressors lead to sexual dimorphism in both acute response and long-term outcome, we hypothesized that our model could lead to gender-based differences in acute stress response and long-term risk of developing MTLE. Male and female pups underwent a freeze-lesion induced cortical microgyrus at P1 and were exposed to HS at P10. Animals were monitored by video-EEG from P90 to P120. Pre and post-procedure plasma corticosterone levels were used to measure stress response at P1 and P10. To confirm the role of sex steroids, androgenized female pups received daily testosterone injections to the mother pre-natally and post-natally for nine days while undergoing both insults. We demonstrated that after both insults females did not develop MTLE while all males did. This correlated with a rise in corticosterone levels at P1 following the lesion in males only. Interestingly, all androgenized females showed a similar rise in corticosterone at P1, and also developed MTLE. Moreover, we found that the cortical lesion significantly decreased the latency to generalized convulsion during hyperthermia at P10 in both genders. The cortical dysplasia volumes at adulthood were also similar between male and female individuals. Our data demonstrate sexual dimorphism in long-term vulnerability to develop epilepsy in the lesion + hyperthermia animal model of MTLE and suggest that the response to early-life stress at P1 contributes significantly to epileptogenesis in a

Juvenile raptors often travel thousands of kilometers from the time they leave their natal areas to the time they enter a breeding population. Documenting movements and identifying areas used by raptors before they enter a breeding population is important for understanding the factors that influence their survival. In North America, juvenile Gyrfalcons (Falco rusticolus) are routinely observed outside the species' breeding range during the nonbreeding season, but the natal origins of these birds are rarely known. We used satellite telemetry to track the movements of juvenile Gyrfalcons during their first months of independence. We instrumented nestlings with lightweight satellite transmitters within 10 d of estimated fledging dates on the Seward Peninsula in western Alaska and in Denali National Park (Denali) in interior Alaska. Gyrfalcons spent an average of 41.4 ± 6.1 d (range  =  30–50 d) in their natal areas after fledging. The mean departure date from natal areas was 27 August ± 6.4 d. We tracked 15 individuals for an average of 70.5 ± 28.1 d post-departure; Gyrfalcons moved from 105 to 4299 km during this period and tended to move greater distances earlier in the tracking period than later in the tracking period. Gyrfalcons did not establish temporary winter ranges within the tracking period. We identified several movement patterns among Gyrfalcons, including unidirectional long-distance movements, multidirectional long- and short-distance movements, and shorter movements within a local region. Gyrfalcons from the Seward Peninsula remained in western Alaska or flew to eastern Russia with no movements into interior Alaska. In contrast, Gyrfalcons from Denali remained in interior Alaska, flew to northern and western Alaska, or flew to northern Alberta. Gyrfalcons from both study areas tended to move to coastal, riparian, and wetland areas during autumn and early winter. Because juvenile Gyrfalcons dispersed over a large geographic area and across three

The complex processes involved with animal migration have long been a subject of biological interest, and broad-scale movement patterns of many marine turtle populations still remain unresolved. While it is widely accepted that once marine turtles reach sexual maturity they home to natal areas for nesting or reproduction, the role of philopatry to natal areas during other life stages has received less scrutiny, despite widespread evidence across the taxa. Here we report on genetic research that indicates that juvenile hawksbill turtles ( Eretmochelys imbricata ) in the eastern Pacific Ocean use foraging grounds in the region of their natal beaches, a pattern we term natal foraging philopatry. Our findings confirm that traditional views of natal homing solely for reproduction are incomplete and that many marine turtle species exhibit philopatry to natal areas to forage. Our results have important implications for life-history research and conservation of marine turtles and may extend to other wide-ranging marine vertebrates that demonstrate natal philopatry.

The effects of chemical exposures during pregnancy on children's health have been an increasing focus of environmental health research in recent years, leading to greater interest in biomonitoring of chemicals in women of childbearing age in the general population. Measurements of mercury in blood from the National Health and Nutrition Examination Survey are frequently reported for "women of childbearing age," defined to be of ages 16-49 years. The intent is to represent prenatal chemical exposure, but blood mercury levels increase with age. Furthermore, women of different ages have different probabilities of giving birth. We evaluated options to address potential bias in biomonitoring summary statistics for women of childbearing age by accounting for age-specific probabilities of giving birth. We calculated median and 95th percentile levels of mercury, PCBs, and cotinine using these approaches: option 1: women aged 16-49 years without natality adjustment; option 2: women aged 16-39 years without natality adjustment; option 3: women aged 16-49 years, adjusted for natality by age; option 4: women aged 16-49 years, adjusted for natality by age and race/ethnicity. Among the three chemicals examined, the choice of option has the greatest impact on estimated levels of serum PCBs, which are strongly associated with age. Serum cotinine levels among Black non-Hispanic women of childbearing age are understated when age-specific natality is not considered. For characterizing in utero exposures, adjustment using age-specific natality provides a substantial improvement in estimation of biomonitoring summary statistics. Copyright © 2010 Elsevier Inc.

Early-Life Nutrition and Neurodevelopment: Use of the Piglet as a Translational Model12

Mudd, Austin T

2017-01-01

Optimal nutrition early in life is critical to ensure proper structural and functional development of infant organ systems. Although pediatric nutrition historically has emphasized research on the relation between nutrition, growth rates, and gastrointestinal maturation, efforts increasingly have focused on how nutrition influences neurodevelopment. The provision of human milk is considered the gold standard in pediatric nutrition; thus, there is interest in understanding how functional nutrients and bioactive components in milk may modulate developmental processes. The piglet has emerged as an important translational model for studying neurodevelopmental outcomes influenced by pediatric nutrition. Given the comparable nutritional requirements and strikingly similar brain developmental patterns between young pigs and humans, the piglet is being used increasingly in developmental nutritional neuroscience studies. The piglet primarily has been used to assess the effects of dietary fatty acids and their accretion in the brain throughout neurodevelopment. However, recent research indicates that other dietary components, including choline, iron, cholesterol, gangliosides, and sialic acid, among other compounds, also affect neurodevelopment in the pig model. Moreover, novel analytical techniques, including but not limited to MRI, behavioral assessments, and molecular quantification, allow for a more holistic understanding of how nutrition affects neurodevelopmental patterns. By combining early-life nutritional interventions with innovative analytical approaches, opportunities abound to quantify factors affecting neurodevelopmental trajectories in the neonate. This review discusses research using the translational pig model with primary emphasis on early-life nutrition interventions assessing neurodevelopment outcomes, while also discussing nutritionally-sensitive methods to characterize brain maturation.

DNA methylation was reported as a possible stress-adaptation mechanism involved in the transcriptional regulation of stress responsive genes. Limited data are available on effects of psychological stress and early-life nutritional stress on DNA methylation regulators [DNMTs: DNA (cytosine-5)-methyltransferase 1 (DNMT1), DNMT1 associated protein (DMAP1), DNMT 3 alpha (DNMT3A) and beta (DNMT3B)] in avian species. The objectives of this study were to: (1) investigate changes in expression of DNMT1, DMAP1, DNMT3A, and DNMT3B following acute (AS) or chronic immobilization stress (CS); (2) test immediate effect of early-life nutritional stress [food deprivation (FD) for 12 h (12hFD) or 36 h (36hFD) at the post-hatching period] on expression of DNA methylation regulators and glucocorticoid receptor (GR), and the long-term effect of early-life nutritional stress at 6 weeks of age. Expression of DNMTs and plasma corticosterone (CORT) concentration decreased by CS compared to AS (p < 0.05), indicating differential roles of DNA methylation regulators in the stress response. Plasma CORT at 12hFD and 36hFD birds increased compared to control birds (12hF and 36hF), but there were no significant differences in plasma CORT of 12hFD and 36hFD birds at 6 weeks of age compared to 6 week controls. DNMT1, DMAP1, and DNMT3B expression in the anterior pituitary increased by 12hFD, but decreased at 36hFD compared to their controls (P < 0.05). In liver, DNMT1, DNMT3A, and DNMT3B expression decreased by 12hFD, however, no significant changes occurred at 36hFD. Expression of DMAP1, DNMT3A, and DNMT3B in anterior pituitary and DMAP1 and DNMT3A expression in liver at 6 weeks of age were higher in 36hFD stressed birds compared to controls as well as 12hFD stressed birds. Hepatic GR expression decreased by 12hFD and increased by 36hFD (p < 0.05). Expression patterns of GR in the liver of FD stress-induced birds persisted until 6 weeks of age, suggesting the possible lifelong involvement of liver

There is no branch of medicine in which nutritional considerations do not play some part. Overnutrition, undernutrition or unbalanced nutrition are the major causes of ill health in the world. Conversely, illness causes important nutritional and metabolic problems. The spectrum from lack to excess of nutrients is seamless as a clinical and scientific discipline, the two extremes being linked by the Barker effect by which intrauterine malnutrition and low birth weight predispose to obesity, diabetes and CVD in later life. However, the teaching of nutrition in medical and nursing schools remains sparse. Nutritional care cannot be practised satisfactorily in isolation from other aspects of management, since factors such as drugs, surgery and fluid and electrolyte balance affect nutritional status. Nutritional treatment may also have adverse or beneficial effects according to the composition, amount and mode of delivery of the diet and the clinical context in which it is given. Any benefits of nutritional support may also be negated by shortcomings in other aspects of treatment and must therefore be fully integrated into overall care. One example of this approach is the enhanced recovery after a surgery protocol incorporating immediate pre-operative carbohydrate and early post-operative oral intake with strict attention to zero fluid balance, epidural analgesia and early mobilisation. Other examples include the deleterious effect on surgical outcome of salt and water overload or hyperglycaemia, either of which may negate the benefits of nutritional support. There is a need, therefore, to integrate clinical nutrition more closely, not just into medical and surgical practice, but also into the organisation of health services in the hospital and the community, and into the training of doctors and nurses. Societies originally devoted to parenteral and enteral nutrition need to widen their scope to embrace wider aspects of clinical nutrition.

Sucrose exposure in early life alters adult motivation and weight gain.

The cause of the current increase in obesity in westernized nations is poorly understood but is frequently attributed to a 'thrifty genotype,' an evolutionary predisposition to store calories in times of plenty to protect against future scarcity. In modern, industrialized environments that provide a ready, uninterrupted supply of energy-rich foods at low cost, this genetic predisposition is hypothesized to lead to obesity. Children are also exposed to this 'obesogenic' environment; however, whether such early dietary experience has developmental effects and contributes to adult vulnerability to obesity is unknown. Using mice, we tested the hypothesis that dietary experience during childhood and adolescence affects adult obesity risk. We gave mice unlimited or no access to sucrose for a short period post-weaning and measured sucrose-seeking, food consumption, and weight gain in adulthood. Unlimited access to sucrose early in life reduced sucrose-seeking when work was required to obtain it. When high-sugar/high-fat dietary options were made freely-available, however, the sucrose-exposed mice gained more weight than mice without early sucrose exposure. These results suggest that early, unlimited exposure to sucrose reduces motivation to acquire sucrose but promotes weight gain in adulthood when the cost of acquiring palatable, energy dense foods is low. This study demonstrates that early post-weaning experience can modify the expression of a 'thrifty genotype' and alter an adult animal's response to its environment, a finding consistent with evidence of pre- and peri-natal programming of adult obesity risk by maternal nutritional status. Our findings suggest the window for developmental effects of diet may extend into childhood, an observation with potentially important implications for both research and public policy in addressing the rising incidence of obesity.

Skeletal growth by endochondral ossification involves tightly coordinated chondrocyte differentiation that creates reserve, proliferating, prehypertrophic, and hypertrophic cartilage zones in the growth plate. Many human skeletal disorders result from mutations in cartilage extracellular matrix (ECM) components that compromise both ECM architecture and chondrocyte function. Understanding normal cartilage development, composition, and structure is therefore vital to unravel these disease mechanisms. To study this intricate process in vivo by proteomics, we analyzed mouse femoral head cartilage at developmental stages enriched in either immature chondrocytes or maturing/hypertrophic chondrocytes (post-natal days 3 and 21, respectively). Using LTQ-Orbitrap tandem mass spectrometry, we identified 703 cartilage proteins. Differentially abundant proteins (q < 0.01) included prototypic markers for both early and late chondrocyte differentiation (epiphycan and collagen X, respectively) and novel ECM and cell adhesion proteins with no previously described roles in cartilage development (tenascin X, vitrin, Urb, emilin-1, and the sushi repeat-containing proteins SRPX and SRPX2). Meta-analysis of cartilage development in vivo and an in vitro chondrocyte culture model (Wilson, R., Diseberg, A. F., Gordon, L., Zivkovic, S., Tatarczuch, L., Mackie, E. J., Gorman, J.

Immunolocalization of Urb, vitrin, and CILP-2 indicated specific roles at different maturation stages. In addition to ECM-related changes, we provide the first biochemical evidence of changing endoplasmic reticulum function during

Cancer wasting and quality of life react to early individualized nutritional counselling!

To devise a meaningful nutritional therapy in cancer, a greater understanding of nutritional dimensions as well as patients' expectations and disease impact is essential. We have shown that nutritional deterioration in patients with gastrointestinal and head and neck cancer was multifactorial and mainly determined by the tumour burden and location. In a larger cohort, stage and location were yet again the major determinants of patients' quality of life (QoL), despite the fact that nutritional deterioration combined with intake deficits were functionally more relevant than cancer stage. Based on this framework, the potential role of integrated oral nutritional support on outcomes was investigated. In a pilot study using individualized nutritional counselling on a heterogeneous patient population, the achieved improvement of nutritional intake was proportional to a better QoL. The role of early nutritional support was further analysed in a prospective randomized controlled trial in head and neck cancer patients stratified by stage undergoing radiotherapy. Pre-defined outcomes were: nutritional status and intake, morbidity and QoL, at the end and 3 months after radiotherapy. Nutritional interventions, only given during radiotherapy, consisted of three randomization arms: (1) individualized nutritional counselling vs. (2) ad libitum diet+high protein supplements vs. (3) ad libitum diet. Nutritional interventions 1 and 2 positively influenced outcomes during radiotherapy; however, 3 months after its completion individualized nutritional counselling was the single method capable of sustaining a significant impact on patients' outcomes. The early provision of the appropriate mixture of foods and textures using regular foods may modulate outcomes in cancer patients.

Early gut wall integrity loss and local intestinal inflammation are associated with the development of inflammatory complications in surgical and trauma patients. Prevention of these intestinal events is a potential target for therapies aimed to control systemic inflammation. Previously, we demonstrated in a rodent shock model that lipid-rich enteral nutrition attenuated systemic inflammation and prevented organ damage through a cholecystokinin receptor-dependent vagal pathway. The influence of lipid-rich nutrition on very early intestinal compromise as seen after shock is investigated. Next, the involvement of cholecystokinin receptors on the nutritional modulation of immediate gut integrity loss and intestinal inflammation is studied. Randomized controlled in vivo study. University research unit. Male Sprague-Dawley rats. Liquid lipid-rich nutrition or control low-lipid feeding was administered per gavage before hemorrhagic shock. Cholecystokinin receptor antagonists were used to investigate involvement of the vagal antiinflammatory pathway. Gut permeability to horseradish peroxidase increased as soon as 30 mins postshock and was prevented by lipid-rich nutrition compared with low-lipid (p<.01) and fasted controls (p<.001). Furthermore, lipid-rich nutrition reduced plasma levels of enterocyte damage marker ileal lipid binding protein at 60 mins (p<.05). Early gut barrier dysfunction correlated with rat mast cell protease plasma concentrations at 30 mins (rs=0.67; p<.001) and intestinal myeloperoxidase levels at 60 mins (rs=0.58; p<.05). Lipid-rich nutrition significantly reduced plasma rat mast cell protease (p<.01) and myeloperoxidase (p<.05) before systemic inflammation was detectable. Protective effects of lipid-rich nutrition were abrogated by cholecystokinin receptor antagonists (horseradish peroxidase; p<.05 and rat mast cell protease; p<.05). Lipid-rich enteral nutrition prevents early gut barrier loss, enterocyte damage, and local intestinal inflammation

Ataxia-telangiectasia (A-T) is a rare genomic syndrome resulting in severe disability. Chronic childhood disorders can profoundly influence growth and development. Nutrition-related issues in A-T are not well described, and there are no nutritional guidelines. This study investigated the nutrition-related characteristics and behaviours of Australian A-T patients attending a national clinic. A cross-sectional analysis of 13 A-T patients (nine females; aged: 4-23 years): nutritional status was assessed by anthropometric and body cell mass (BCM) calculations. Parents reported their child's diet history and physical and behavioural factors that affect nutrition including fatigue and need for assistance. Ten (77%) had short stature (height for age z scores <-1), and seven (54%) were underweight for height (weight/height z scores <-1). Significant malnutrition (BCM z scores <-2) was detected in nine (69%) including the one adult who was severely malnourished. Malnutrition increased significantly with age (BCM for height z scores and age, r = -0.937, P < 0.001). Eight (62%) patients ate poorly compared with estimated energy requirement for weight. Poor diet quality was characterised by high fat and sugar choices. Parents reported significant nutritional barriers as chronic tiredness and the need for care giver assistance with meals. This study confirms profound malnutrition in Australian A-T patients. Poor intakes and diet quality suggest the need for early nutrition intervention. Ongoing support for families and early discussions on tube feeding are required to address changing needs in childhood and likely nutritional decline into adulthood. A prospective study is required to assess feasibility and effectiveness of nutrition interventions in young people with A-T. © 2015 The Authors.

Background Little is known about the association between malnutrition and the chances of returning home from post-acute facilities in older adult patients. This study aimed to understand whether malnutrition and malnutrition-related factors would be determinants for returning home and activities of daily living (ADL) at discharge after post-acute care. Methods Patients aged ≥65 years living at home before the onset of an acute disease and admitted to a post-acute ward were enrolled (n=207) in this prospective observational study. Malnutrition was defined based on the criteria of the European Society for Clinical Nutrition and Metabolism. Nutritional parameters included the nutritional intake at the time of admission and oral conditions evaluated by the Oral Health Assessment Tool (OHAT). The Barthel Index was used to assess daily activities. A Cox regression analysis of the length of stay was performed. Multivariable linear regression analyses to determine associations between malnutrition, returning home, and ADL at discharge were performed, after adjusting the variables of acute care setting. Results The mean patient age was 84.7±6.7 years; 38% were men. European Society for Clinical Nutrition and Metabolism-defined malnutrition was observed in 129 (62.3%) patients, and 118 (57.0%) of all patients returned home. Multivariable regression analyses showed that malnutrition was a negative predictor of returning home (hazard ratio: 0.517 [0.351–0.761], p=0.001), and an increase in the nutritional intake (kcal/kg/d) was a positive predictor of the Barthel Index at discharge (coefficient: 0.34±0.15, p=0.021). The OHAT was not associated with returning home and ADL. Conclusion Malnutrition and nutritional intake are associated with returning home and ADL at discharge, respectively, after post-acute care. Further studies investigating the effects of a nutritional intervention for post-acute patients would be necessary. PMID:29416323

Community family planning programmes in South Africa arose from the controversial apartheid history of controlling the African population while encouraging the growth of European migrant population. Post-apartheid population policies shifted away from population control to aligning policies to the global agenda that placed emphasis on the link between population and development. The focus on population and development polices in post-apartheid South Africa is on social equality, justice and peace rather than controlling sections of the population. Given the shift, this paper interrogates the conceptions of contraceptive use among rural communities in KwaZulu-Natal. Our primary objective is to understand the dynamics surrounding access to and use of family planning services in peri-urban and rural areas of KwaZulu-Natal. Using focus group data, the findings of the study suggest that different social categories interact with the family planning programmes differently. How teenagers and married women perceive the value of family planning differs. Gender differences regarding the use of condoms are also evident. The paper attempts to grapple with the non-use of condoms despite the knowledge that these prevent pregnancy and provide protection from sexually-transmitted diseases. The contribution of this paper lies in its identification of socio-cultural factors and the political economy underlying the different attitudes towards contraceptive use in rural KwaZulu-Natal.

Malnutrition is common in infants and children with congenital heart disease (CHD). Cardiac surgery has improved patient survival and nutritional status. To evaluate the impact of cardiac surgery on nutritional status of pediatric patients with CHD. A prospective cohort study was conducted in pediatric patients with CHD, admitted for cardiac surgery at Queen Sirikit National Institute of Child Health (QSNICH), Bangkok, from August 1st, 2002 to 2003. Demographic data, cardiac and related problems were obtained before operation. Anthropometry was performed at the presentation and post cardiac surgery. Nutritional status was assessed by Z-score of weight for age (ZWA), weight for height (ZWH) and height for age (ZHA). Malnutrition was defined as Z-score <- 2 and compared pre- and post-operation using Chi-square. Paired t-test was used to compare mean Z-score and p-value < 0.05 was statistically significant. All of 161 pediatric patients with CHD undergoing cardiac surgery were 41% males and 59% females. Patients' age ranged from 1 month to 15 years. The related problems included low birth weight (28%) and feeding problem (58%). The most common CHD was ventricular septal defect (29%). The nutritional status of the patients before surgery was defined as normal 57%, malnutrition 40% and over-nutrition 3%. Malnutrition included underweight 28%, wasting 22% and stunting 16%. Post cardiac surgery, the means of ZWA, ZWH and ZHA were significantly increased and the prevalence of underweight and wasting were decreased to 17% and 6% respectively, with statistically significant from the baseline (p < 0.05). Malnutrition was found in 40% of pediatric patients with CHD and cardiac surgery has a significant positive effect on weight gain and nutritional status.

Nutritional deficiency of post-bariatric surgery body contouring patients: what every plastic surgeon should know.

Bariatric surgery, particularly the Roux-en-Y gastric bypass, is currently the most effective method of sustainable weight loss for the morbidly obese patient population. Unfortunately, the nutritional adequacy of the postoperative diet has frequently been overlooked, and in the months to years that follow, many nutritional deficiencies have become apparent. Furthermore, once weight loss has reached a plateau, many patients become candidates for body contouring surgery and other aesthetic operations. The aim of this review was to highlight the nutritional deficiencies of post-bariatric surgery patients as related to planned body contouring surgery. This review was prepared by an extensive search of the bariatric surgery literature. The current data indicate that many post-bariatric surgery patients have protein-calorie malnutrition as well as various vitamins and mineral deficiencies that may limit optimal health and healing. It is essential that those plastic surgeons who treat post-bariatric surgery patients are aware of these nutritional deficiencies, which can be minimized by adhering to eating guidelines and supplemental prescriptions. Although there are many studies documenting relationships between malnutrition and poor wound healing, the optimal nutrient intake in the post-bariatric surgery state to promote wound healing is unknown. It is, however, clear that proteins, vitamin A, vitamin C, arginine, glutamine, zinc, and selenium have significant beneficial effects on wound healing and optimizing the immune system.

Hypoglycemia is increasingly recognized as a complication of bariatric surgery. Although medications are often required, medical nutrition therapy remains the key cornerstone for successful prevention of hypoglycemia in patients with post-bariatric hypoglycemia (PBH). We provide suggested approaches to the dietary management of PBH, incorporating data from both the medical literature and extensive clinical experience in an academic referral center for PBH. The overall goal of medical nutrition therapy for PBH is to reduce postprandial surges in glucose, which often trigger surges in insulin secretion and promote subsequent hypoglycemia. Thus, strategies focus on controlled portions of low glycemic index carbohydrates, avoidance of rapidly-absorbed carbohydrates, adjustment of timing of meals and snacks, and attention to personal and cultural barriers to implementation.

The impact of nutritional deficiencies early in life in determining life-history variation in organisms is well recognized. The negative effects of inbreeding on fitness are also well known. Contrary to studies on vertebrates, studies on invertebrates are not consistent with the observation that inbreeding compromises resistance to parasites and pathogens. In this study, we investigated the effect of early nutrition on the magnitude of inbreeding depression in development time, adult body size and adult resistance to the bacterium Serratia marcescens in Drosophila melanogaster. We found that early nutritional environment had no effect on the magnitude of inbreeding depression in development time or adult body size but may have played a small role in adult resistance to the bacterial infection. Estimates of heritabilities for development time under the poor nutritional environment were larger than those measured under the standard nutritional conditions. © 2010 The Authors.

At The Power of Programming 2014 Conference, researchers from multiple disciplines presented and discussed the effects of early nutrition and other environmental cues during the first thousand days of life and beyond on the lifelong risk of noncommunicable diseases. This paper aims to summarize the concepts and some of the first achievements of the EarlyNutrition research project that initiated the conference. The EarlyNutrition consortium is a multinational, multidisciplinary research collaboration of researchers from Europe, the USA, and Australia. A focus is placed on exploration of the developmental origins of obesity, adiposity, and related health outcomes. Here we report on the first findings of experimental approaches, cohort studies, randomized clinical trials, and systematic reviews of current information, as well as position papers, which have all been developed with the involvement of project partners. We conclude that the EarlyNutrition project has successfully established itself during the first 2 project years as a very strong platform for collaborative research on early programming effects. The first results, available already at this early stage of the project, point to great opportunities for health prevention strategies via the implementation of dietary and lifestyle modifications, with large effect sizes. Further results are expected which should support improved recommendations and related policies for optimized nutrition and lifestyle choices before and during pregnancy, in infancy, and in early childhood. © 2014 S.

The Power of Programming conference 2016 at Ludwig-Maximilians-Universität Munich brought together about 600 researchers and other stakeholders from around the world who reviewed the recent evidence on the lasting health impact of environment and nutrition during early life, from pre-pregnancy to early childhood. The conference was hosted by the Early Nutrition Project, a multidisciplinary research collaboration funded by the European Commission with collaborating researchers from 35 institutions in 15 countries in Europe, the United States and Australia. The project explores the early origins of obesity, adiposity and associated non-communicable diseases, underlying mechanisms and opportunities for prevention. The project also proactively supports translational application of research findings. In fact, some existing evidence has already been rapidly adopted into policy, regulatory standards and practice. Further, broad dissemination of findings is achieved through the established digital eLearning platform of the Early Nutrition eAcademy, video clip-based learning and graphically supported messaging to consumers. The project demonstrated powerful effects of early metabolic programming on later health. Compared to other common prevention strategies, modifying risk trajectories in early life can achieve a much larger risk reduction and be more cost-effective. While some effective prevention strategies have been promptly implemented in policy and guidelines, legislation and practice, in other areas, the uptake is limited by a paucity of quality human intervention trials and insufficient evaluation of the feasibility of implementation and econometric impact. This needs to be strengthened by future collaborative research work. © 2017 S. Karger AG, Basel.

The mechanisms by which early chronic lead (Pb) exposure alter brain development have not been identified. We examined neuroimmune system effects in C57BL/6J mice with Pb exposure, including levels that may be common among children in lower socioeconomic income environments. Pups were exposed via dams’ drinking water from birth to post-natal day 28 to low, high or no Pb conditions. We compared gene expression of neuroinflammatory markers (study 1); and microglial mean cell body volume and mean cell body number in dentate gyrus, and dentate gyrus volume (study 2). Blood Pb levels in exposed animals at sacrifice (post-natal day 28) ranged from 2.66 to 20.31 μg/dL. Only interleukin-6 (IL6) differed between groups and reductions were dose-dependent. Microglia cell body number also differed between groups and reductions were dose-dependent. As compared with controls, microglia cell body volume was greater but highly variable in only low-dose animals; dentate gyri volumes in low- and high-dose animals were reduced. The results did not support a model of increased neuroinflammation. Instead, early chronic exposure to Pb disrupted microglia via damage to, loss of, or lack of proliferation of microglia in the developing brains of Pb-exposed animals. PMID:23598043

Early childhood temperament is increasingly recognized as an important attribute that may impact screen time use, outdoor play and childhood obesity. The relationship between temperament and nutrition in preschool children is less clear. The objective of the study is to investigate if temperament dimensions (negative affectivity, effortful control and surgency) in early childhood are associated with nutritional risk factors. Six hundred seventy-eight children were followed (mean age at baseline visit 3.1 years; mean time to follow-up 16.5 months). Parents reported on child temperament and nutritional risk factors during regularly scheduled well-child clinic visits. A mixed effect model demonstrated a significant association between higher negative affectivity (1.03; 95% CI 0.69 to 1.37) and higher effortful control (-0.88; 95% CI -1.27 to -0.49) on concurrent nutritional risk, independent of covariates. Multivariate linear regression analysis identified that higher effortful control, and not negative affectivity, was significantly associated with a decrease in nutritional risk (-0.67; 95% CI -1.10 to -0.24) over time, independent of covariates. There was no relationship identified between surgency and nutritional risk. Three-year-old children with higher effortful control had reduced nutritional risk at 5 years of age. Future nutritional risk prevention strategies may benefit from interventions to increase effortful control in early childhood. © 2016 World Obesity Federation.

Current less invasive surgical techniques, the use of new analgesic and anesthetic drugs, and early mobilization ("multimodal surgical strategies") reduce the occurrence of post-surgery paralytic ileus and vomiting, making possible early nutrition by the digestive route. With these premises, a nutrition protocol was designed for its implementation in colorectal pathology susceptible of laparoscopy-assisted surgery. to assess the efficacy of this protocol that comprises 3 phases. Phase I: home preparation with 7 days duration; low-residues and insoluble fiber diet, supplemented with 400 mL of hyperproteic polymeric formula with no lactose or fiber, bowel cleansing 2 days prior to surgery and hydration with water, sugared infusions, and vegetable broth. Phase II: immediate post-surgical period with watery diet for 3 days with polymeric diet with no fiber. Phase III: semi-solid diet with no residues, nutritional formula and progressive reintroduction of food intake in four stages of varying duration according to surgery and digestive tolerance. prospective study performed at our hospital with patients from our influence area, from February 2003 to May 2004, including 25 patients, 19 men and 6 women, with mean age of 63.3 years (range = 33-79) and mean body mass index of 26.25 kg/m2 (range = 20.84-31.3), all of them suffering from colorectal pathology susceptible of laparoscopy-assisted surgery, and to which the study protocol was applied. Fourteen left hemicolectomies, 5 right hemicolectomies, 4 low anterior resections with protective colostomy, and subtotal colectomies and lateral ileostomy were done. Final diagnoses were: 3 diverticular diseases; 3 adenomas; 7 rectosigmoidal neoplasms; and 12 large bowel neoplasms in other locations.

Malnutrition substantially impacts the health outcomes of children. Globally, the childhood prevalence of overweight and obesity has increased, while underweight and stunting (though decreasing) continues to pose a major public health challenge. In low- to middle-income countries, a mixed pattern of over- and undernutrition (nutritional transition) can exist in communities. To describe the prevalence of malnutrition among female learners in the Nongoma and Ceza districts in Zululand, KwaZulu-Natal (KZN). We performed a secondary analysis of anthropometric data collected during the 2011 HPV Vaccination Demonstration Project. School health teams, comprising trained nurses, measured the height (in cm) and weight (in kg) of 963 female learners in 31 primary schools. Internationally accepted standardised measures were used as cut-offs for defining overweight, obesity, underweight and stunting. We found evidence of both under- and overnutrition. Overall, 9% of female learners were overweight, 3.8% obese, 4% underweight and 9.2% stunted (using WHO/NCHS criteria). The highest levels of stunting were in the 11 - 12-year age groups, of underweight in the 10-year age group, of overweight and obesity in the 9 - 10-year age groups. Moreover, a proportion of underweight (17.4%), overweight (11.1%) and obese (22.9%) learners were also stunted. Our study describes the prevalence of overweight and obesity, wasting and stunting of female learners in KZN and suggests the presence of a nutritional transition in these rural communities; however, further studies are needed. Our findings emphasise the need for health promotion and education programs in schools.

In model organisms both the nutrition of the mother and the young offspring could induce long-lasting transcriptional changes in tissues. In livestock, such changes could have important roles in determining nutrient use and meat quality. The main objective was to evaluate if plane of maternal nutrition during late-gestation and weaning age alter the offspring’s Longissimus muscle (LM) transcriptome, animal performance, and metabolic hormones. Whole-transcriptome microarray analysis was performed on LM samples of early (EW) and normal weaned (NW) Angus × Simmental calves born to grazing cows receiving no supplement [low plane of nutrition (LPN)] or 2.3 kg high-grain mix/day [medium plane of nutrition (MPN)] during the last 105 days of gestation. Biopsies of LM were harvested at 78 (EW), 187 (NW) and 354 (before slaughter) days of age. Despite greater feed intake in MPN offspring, blood insulin was greater in LPN offspring. Carcass intramuscular fat content was greater in EW offspring. Bioinformatics analysis of the transcriptome highlighted a modest overall response to maternal plane of nutrition, resulting in only 35 differentially expressed genes (DEG). However, weaning age and a high-grain diet (EW) strongly impacted the transcriptome (DEG = 167), especially causing a lipogenic program activation. In addition, between 78 and 187 days of age, EW steers had an activation of the innate immune system due presumably to macrophage infiltration of intramuscular fat. Between 187 and 354 days of age (the “finishing” phase), NW steers had an activation of the lipogenic transcriptome machinery, while EW steers had a clear inhibition through the epigenetic control of histone acetylases. Results underscored the need to conduct further studies to understand better the functional outcome of transcriptome changes induced in the offspring by pre- and post-natal nutrition. Additional knowledge on molecular and functional outcomes would help produce more efficient beef

Post-natal hypoxic activity of the central respiratory command is improved in transgenic mice overexpressing Epo in the brain.

PubMed

Caravagna, Céline; Kinkead, Richard; Soliz, Jorge

2014-08-15

Previous studies indicated that erythropoietin modulates central respiratory command in mice. Specifically, a one-hour incubation of the brainstems with erythropoietin attenuates hypoxia-induced central respiratory depression. Here, using transgenic mice constitutively overexpressing erythropoietin specifically in the brain (Tg21), we investigated the effect of chronic erythropoietin stimulation on central respiratory command activity during post-natal development. In vitro brainstem-spinal cord preparations from mice at 0 (P0) or 3 days of age (P3) were used to record the fictive inspiratory activity from the C4 ventral root. Our results show that erythropoietin already stimulates the hypoxic burst frequency at P0, and at P3, erythropoietin effectively stimulates the hypoxic burst frequency and amplitude. Because the maturation of the central respiratory command in mice is characterized by a decrease in the burst frequency with age, our results also suggest that erythropoietin accelerates the maturation of the newborn respiratory network and its response to hypoxia.

The early to middle childhood years are a critical period for child neurodevelopment. Nutritional deficiencies, infection and inflammation are major contributors to impaired child neurodevelopment in these years, particularly in low resource settings. This review identifies global research priorities relating to nutrition, infection, and inflammation in early to middle childhood neurodevelopment. Research priority areas identified include: 1) assessment of how nutrition, infection or inflammation in the pre-conception, prenatal and infancy periods (or interventions in these periods) affect function in early to middle childhood; 2) assessment of whether effects of nutritional interventions vary by poverty or inflammation; 3) determination of the feasibility of pre-school and school-based integrated nutritional interventions; 4) improved assessment of the epidemiology of infection- and inflammation-related neurodevelopmental impairment (NDI); 5) identification of mechanisms through which infection causes NDI; 6) identification of non-infectious causes of inflammation-related NDI and interventions for causes already identified (e.g, environmental factors); and 7) studies on the effects of interactions between nutritional, infectious and inflammatory factors on neurodevelopment in early to middle childhood. Areas of emerging importance which require further study include the effects of maternal Zika virus infection, childhood environmental enteropathy, and alterations in the child’s microbiome on neurodevelopment in early to middle childhood. Research in these key areas will be critical to the development of interventions to optimize the neurodevelopmental potential of children worldwide in the early to middle childhood years.

In an attempt to reduce the high extinction risk inherent to small island populations, we translocated wild Laysan teal Anas laysanensis to a portion of its presumed prehistoric range. Most avian translocations lack the strategic post-release monitoring needed to assess early population establishment or failure. Therefore, we monitored the survival and reproduction of all founders, and their first-generation offspring using radio telemetry for 2 years after the first release. Forty-two Laysan teal were sourced directly from the only extant population on Laysan Island and transported 2 days by ship to Midway Atoll. All birds survived the translocation with nutritional and veterinary support, and spent between 4 and 14 days in captivity. Post-release survival of 42 founders was 0.857 (95% CI 0.86-0.99) during 2004-2006 or annualized 0.92 (95% CI 0.83-0.98). Seventeen of 18 founding hens attempted nesting in the first two breeding seasons. Fledgling success was 0.57 (95% CI 0.55-0.60) in 2005 and 0.63 (95% CI 0.62-0.64) in 2006. The effective founding female population (Ne) was 13. We applied these initial demographic rates to model population growth. The nascent population size increased to >100 after only 2 years post-release (?? = 1.73). If this growth rate continues, the size of the Midway population could surpass the source population before 2010. ?? 2008 The Authors. Journal compilation ?? 2008 The Zoological Society of London.

Objective: To investigate the effects of early enteral nutrition (EEN) in the treatment of patients with severe burns. Methods: Medical records of 52 patients with severe burns hospitalized in the three affiliations of authors from August to September in 2014 were retrospectively analyzed and divided into EEN group ( n =28) and non-early enteral nutrition (NEEN) group ( n =24) according to the initiation time of enteral nutrition. On the basis of routine treatment, enteral nutrition was given to patients in group EEN within post injury day (POD) 3, while enteral nutrition was given to patients in group NEEN after POD 3. The following items were compared between patients of the two groups, such as the ratio of enteral nutrition intake to total energy intake, the ratio of parenteral nutrition intake to total energy intake, the ratio of total energy intake to energy target on POD 1, 2, 3, 4, 5, 6, 7, 14, 21, and 28, the levels of prealbumin, serum creatinine, blood urea nitrogen, total bilirubin, direct bilirubin, and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score on POD 1, 3, 7, 14, and 28, the first operation time, the number of operations, and the frequencies of abdominal distension, diarrhea, vomiting, aspiration, catheter blockage, and low blood sugar within POD 28. Data were processed with χ (2)test, t test, Wilcoxon rank sum test, and Bonferroni correction. Results: (1) The ratio of parenteral nutrition intake to total energy intake of patients in group EEN on POD 1 was obviously lower than that in group NEEN ( Z =2.078, P <0.05). The ratio of enteral nutrition intake to total energy intake and the ratio of total energy intake to energy target of patients in group EEN on POD 2 and 3 were obviously higher than those in group NEEN ( Z =5.766, 6.404, t =4.907, 6.378, P <0.01). The ratio of total energy intake to energy target of patients in group EEN was obviously lower than that in group NEEN on POD 4, 5, 6, and 7 ( t =4.635, 2.547, 3

However, perinatal women living with HIV in Tanzania have reported an even greater prevalence of depression (43-45%). The primary goal of this study was to examine the relationship between maternal depression and infant malnutrition among women living with HIV. The design was a retrospective cohort study within the context of a randomised controlled trial among women living with HIV and their infants. Within this trial, 699 mother-child pairs were analysed for the present study. Although antenatal depression was not associated with infant malnutrition and post-natal depression was negatively associated [relative risk (RR = 0.80, P = 0.04], cumulative depression demonstrated a positive association with infant wasting (RR = 1.08, P < 0.01) and underweight (RR = 1.03, P < 0.01) after controlling for confounding factors. Variation in the association between depression and infant nutritional status was observed for episodic vs. chronic depression. These findings suggest that providing evidence-based services for persistent depression among women living with HIV may have an effect on infant malnutrition. In addition, other positive outcomes may be related to infant cognitive development as well as HIV disease prognosis and survival among women. © 2014 John Wiley & Sons Ltd.

Early Child Development and Nutrition: A Review of the Benefits and Challenges of Implementing Integrated Interventions.

Poor nutrition (substandard diet quantity and/or quality resulting in under- or overnutrition) and the lack of early learning opportunities contribute to the loss of developmental potential and life-long health and economic disparities among millions of children aged <5 y. Single-sector interventions representing either early child development (ECD) or nutrition have been linked to positive child development and/or nutritional status, and recommendations currently advocate for the development and testing of integrated interventions. We reviewed the theoretical and practical benefits and challenges of implementing integrated nutrition and ECD interventions along with the evidence for best practice and benefit-cost and concluded that the strong theoretical rationale for integration is more nuanced than the questions that the published empirical evidence have addressed. For example, further research is needed to 1) answer questions related to how integrated messaging influences caregiver characteristics such as well-being, knowledge, and behavior and how these influence early child nutrition and development outcomes; 2) understand population and nutritional contexts in which integrated interventions are beneficial; and 3) explore how varying implementation processes influence the efficacy, uptake, and cost-benefit of integrated nutrition and ECD interventions. © 2016 American Society for Nutrition.

Nutritional Risk Screening-2002 (NRS-2002) and the Malnutrition Universal Screening Tool (MUST) are screening tools for nutritional risk that have also been used to predict post-operative complications and morbidity, though not all studies confirm the reliability of nutritional screening. Our study aims to evaluate the independent predictive value of nutritional risk screening in addition to currently documented medical, surgical and anesthesiological risk factors for post-operative complications, as well as length of hospital stay. This study is a prospective observational cohort study of 129 patients undergoing elective gastro-intestinal-surgery. Patients were screened for nutritional risk upon admission using both MUST and NRS-2002 screening tools. Univariate and multivariate analyses were performed to investigate the independent predictive value of nutritional risk for post-operative complications and length of hospital stay. MUST ≥2 (OR 2.87; 95% CI 1.05-7.87) and peri-operative transfusion (OR 2.78; 95% CI 1.05-7.40) were significant independent predictors for the occurrence of post-operative complications. Peri-operative transfusion (HR 2.40; 95% CI 1.45-4.00), age ≥70 (HR 1.50; 95% CI 1.05-2.16) and open surgery versus laparoscopic surgery (HR 1.39; 95% CI 0.94-2.05) were independent predictors for increased length of hospital stay, whereas American Society of Anesthesiology Score (ASA) and MUST were not. Nutritional risk screening (MUST ≥2) is an independent predictor for post-operative complications, but not for increased length of hospital stay.

Maturation of the mammalian growth axis is thought to be linked to the transition from fetal to post-natal life at birth. However, in an altricial marsupial, the tammar wallaby (Macropus eugenii), this process occurs many months after birth but at a time when the young is at a similar developmental stage to that of neonatal eutherian mammals. Here we manipulate growth rates and demonstrate in slow, normal and fast growing tammar young that nutrition and growth rate affect the time of maturation of the growth axis. Maturation of GH/IGF-I axis components occurred earlier in fast growing young, which had significantly increased hepatic GHR, IGF1 and IGFALS expression, plasma IGF-I concentrations, and significantly decreased plasma GH concentrations compared to age-matched normal young. These data support the hypothesis that the time of maturation of the growth axis depends on the growth rate and maturity of the young, which can be accelerated by changing their nutritional status.

Implantation failure and pregnancy loss are estimated to affect up to 75% of fertilized ova; however as of yet there is limited empirical evidence, particularly at the population level, for understanding the environmental determinants of these losses. The purpose of this review is to summarize the current knowledge on prepregnancy nutrition and early pregnancy outcomes with particular focus on the outcome of spontaneous abortion among pregnancies conceived naturally and early pregnancy end points among pregnancies conceived through in vitro fertilization. To date, there is limited evidence to support associations of prepregnancy vitamin D and caffeine intake with pregnancy loss. There is suggestive data supporting a link between a healthy diet and lower risk of pregnancy loss. High folate and minimal to no alcohol intake prior to conception have the most consistent evidence supporting an association with lower risk of pregnancy loss. PMID:26457232

Pre-term infants who develop bronchopulmonary dysplasia (BPD) are at risk of postnatal growth failure. It has been reported that energy expenditure is higher in infants with BPD than in those without BPD. The aim of the study was to evaluate whether increasing the enteral energy intake of pre-term infants with BPD can improve post-natal growth. This prospective, non-randomised interventional cohort study was designed to assess growth in 57 preterm infants with BPD (gestational age <32 weeks, birth weight <1500 g, and persistent oxygen dependency for up to 28 days of life) fed individually tailored fortified breast milk and/or preterm formula, and a historical control group of 73 pre-term infants with BPD fed breast milk fortified in accordance with the instructions of the manufacturer and/or pre-term formula. Between-group differences in the continuous variables were analysed using Student's t test or the Mann-Whitney test; the discrete variables were compared using the chi-squared test. Linear regression analysis was used to investigate the independent contribution of enteral energy intake to weight gain velocity. The duration of parenteral nutrition was similar in the historical and intervention groups (43.7 ± 30.9 vs 39.6 ± 17.4 days). After the withdrawal of parenteral nutrition, enteral energy intake was higher in the infants in the intervention group with mild or moderate BPD (131 ± 6.3 vs 111 ± 4.6 kcal/kg/day; p < 0.0001) and in those with severe BPD (126 ± 5.3 vs 105 ± 5.1 kcal/kg/day; p < 0.0001), whereas enteral protein intake was similar (3.2 ± 0.27 vs 3.1 ± 0.23 g/kg/day).Weight gain velocity was greater in the infants in the intervention group with mild or moderate BPD (14.7 ± 1.38 vs 11.5 ± 2 g/kg/day, p < 0.0001) and in those with severe BPD (11.9 ± 2.9 vs 8.9 ± 2.3 g/kg/day; p < 0.007).

The benefits and risks of nutritional therapies in the prevention and management of infectious diseases in the developed world are reviewed. There is strong evidence that early enteral feeding of patients prevents infections in a variety of traumatic and surgical illnesses. There is, however, little support for similar early feeding in medical illnesses. Parenteral nutrition increases the risk of infection when compared to enteral feeding or delayed nutrition. The use of gastric feedings appears to be as safe and effective as small bowel feedings. Dietary supplementation with glutamine appears to lower the risk of post-surgical infections and the ingestion of cranberry products has value in preventing urinary tract infections in women.

Polyunsaturated fatty acids (PUFAs) are essential fatty acids, which are critical for brain development and later life cognitive functions. The main brain PUFAs are docosahexaenoic acid (DHA) for the n-3 family and arachidonic acid (ARA) for the n-6 family, which are provided to the post-natal brain by breast milk or infant formula. Recently, the use of dairy lipids (DL) in replacement of vegetable lipids (VL) was revealed to potently promote the accretion of DHA in the developing brain. Brain DHA, in addition to be a key component of brain development, display potent anti-inflammatory activities, which protect the brain from adverse inflammatory events. In this work, we evaluated the protective effect of partial replacement of VL by DL, supplemented or not with DHA and ARA, on post-natal inflammation and its consequence on memory. Mice were fed with diets poor in vegetal n-3 PUFA (Def VL), balanced in vegetal n-3/n-6 PUFA (Bal VL), balanced in dairy lipids (Bal DL) or enriched in DHA and ARA (Supp VL; Supp DL) from the first day of gestation until adulthood. At post-natal day 14 (PND14), pups received a single administration of the endotoxin lipopolysaccharide (LPS) and brain cytokine expression, microglia phenotype and neurogenesis were measured. In a second set of experiments, memory and neurogenesis were measured at adulthood. Overall, our data showed that lipid quality of the diet modulates early life LPS effect on microglia phenotype, brain cytokine expression and neurogenesis at PND14 and memory at adulthood. In particular, Bal DL diet protects from the adverse effect of early life LPS exposure on PND14 neurogenesis and adult spatial memory. Copyright © 2016 Elsevier Ltd. All rights reserved.

We compare binary evolution models with different assumptions about black-hole natal kicks to the first gravitational-wave observations performed by the LIGO detectors. Our comparisons attempt to reconcile merger rate, masses, spins, and spin-orbit misalignments of all current observations with state-of-the-art formation scenarios of binary black holes formed in isolation. We estimate that black holes (BHs) should receive natal kicks at birth of the order of σ ≃200 (50 ) km /s if tidal processes do (not) realign stellar spins. Our estimate is driven by two simple factors. The natal kick dispersion σ is bounded from above because large kicks disrupt too many binaries (reducing the merger rate below the observed value). Conversely, the natal kick distribution is bounded from below because modest kicks are needed to produce a range of spin-orbit misalignments. A distribution of misalignments increases our models' compatibility with LIGO's observations, if all BHs are likely to have natal spins. Unlike related work which adopts a concrete BH natal spin prescription, we explore a range of possible BH natal spin distributions. Within the context of our models, for all of the choices of σ used here and within the context of one simple fiducial parameterized spin distribution, observations favor low BH natal spin.

Nearly all countries in the world today are burdened with malnutrition, manifesting as undernutrition, micronutrient deficiencies, and/or overweight and obesity. Despite some progress, efforts to alleviate malnutrition are hampered by a shortage in number, skills, and geographic coverage, of a workforce for nutrition. Here, we report the findings of the Castel Gandolfo workshop, a convening of experts from diverse fields in March 2014 to consider how to develop the capacity of a global cadre of nutrition professionals for the post-2015 development era. Workshop participants identified several requirements for developing a workforce for nutrition, including an ability to work as part of a multisectoral team; communication, advocacy, and leadership skills to engage decision makers; and a set of technical skills to address future challenges for nutrition. Other opportunities were highlighted that could immediately contribute to capacity development, including the creation of a consortium to link global North and South universities, online training modules for middle managers, and practical, hands-on experiences for frontline nutrition workers. Institutional and organizational support is needed to enable workshop recommendations on education and training to be effectively implemented and sustained. The findings from the Castel Gandolfo workshop can contribute to the delivery of successful nutrition-relevant actions in the face of mounting external pressures and informing and attaining the forthcoming Sustainable Development Goals. © 2015 American Society for Nutrition.

Early Activation of MAPK and Apoptosis in Nutritive Embryos of Calyptraeid Gastropods.

Investigation of alternative phenotypes, different morphologies produced by a single genome, has contributed novel insights into development and evolution. Yet, the mechanisms underlying developmental switch points between alternative phenotypes remain poorly understood. The calyptraeid snails Crepidula navicella and Calyptraea lichen produce two phenotypes: viable and nutritive embryos, where nutritive embryos arrest their development after gastrulation and are ingested by their viable siblings as a form of intracapsular nutrition. Here, we investigate the activity of mitogen-activated protein kinase (MAPK, ERK1/2) and apoptosis during early cleavage. MAPK and apoptosis, found in a previous transcriptomic study, are known to be involved in organization of other spiralian embryos and nutritive embryo development, respectively. In the model Crepidula fornicata, MAPK activation begins at the 16-cell stage. In contrast, we discovered in C. navicella and C. lichen that many embryos begin MAPK activation at the one-cell stage. A subset of embryos shows a similar pattern of MAPK activation to C. fornicata at later stages. In all stages where MAPK is detected, the activation pattern is highly variable, frequently occurring in all quadrants or in multiple tiers of cells. We also detected apoptosis in cleaving embryos, while C. fornicata and Crepidula lessoni, which do not produce nutritive embryos, show no signs of apoptosis during cleavage. Our results show that MAPK and apoptosis are expressed during early development in species with nutritive embryos, and raises the possibility that these processes may play a role and even interact with one another in producing the nutritive embryo phenotype. © 2017 Wiley Periodicals, Inc.

To present the evidence in relation to early life nutrition and foetal programming for adult disease. Epigenetics is a new and growing area of study investigating the impact of the intrauterine environment on the lifelong health of individuals. Discursive paper. Searches were conducted in a range of electronic health databases. Hand searches located additional articles for review. Maternal search terms included: pregnancy; nutrition; diet; obesity; over nutrition; under nutrition. Offspring related search terms included: macrosomia; intrauterine growth restriction; epigenetics; foetal programming; childhood obesity; adolescent obesity; adolescent type 2 diabetes. Results indicate that foetal programming for adult disease occurs in response to particular insults during vulnerable developmental periods. Four main areas of foetal exposure were identified in this review: (1) under nutrition; (2) over nutrition; (3) gestational diabetes mellitus; and (4) infant catch-up growth. Numerous studies also described the trans-generational nature of foetal programming. Overall, foetal exposure to excess or insufficient nutrition during vulnerable developmental periods appears to result in a lifelong predisposition to obesity and adult disease, such as type 2 diabetes and cardiac disease. For the infant who has been undernourished during early life, a predisposition to renal disease also occurs. Pregnancy is a time when women are engaged in health systems and are receptive to health messages. These factors suggest that pregnancy may be an optimal time for dietary education and intervention. There is a particular need for education on healthy diet and for interventions which aim to limit over consumption of calories. © 2015 John Wiley & Sons Ltd.

Cachexia is one of the most widely overlooked of the syndromes that are experienced by cancer patients. This syndrome is especially prevalent among patients with gastroenterology tract cancer. Although the National Comprehensive Cancer Network (NCCN) issued palliative-care practice guidelines for cachexia in 2015, guidelines have yet to be issued for the clinical setting. The authors reviewed the literature and applied their clinical experience to create an approach for identifying the degree of cachexia in a post-operative patient with periampullary cancer. This approach assesses the nutritional status, physical status, laboratory results, and gastrointestinal system functions of the patient using the Cachexia Assessment Scale (CAS) and NCCN Practice Guidelines for Cachexia. The patient improved under nursing care with an increase in nutritional intake and physical activity facilitating their process of post-surgical physical recovery. The authors hope that this experience using the combined CAS-NCCN Practice Guidelines will help clinical caregivers better understand how to apply the relevant guidelines in clinical settings. The developed approach may help nurses assess the comprehensive nutrition status of patients and related factors in order to provide interventions that will decrease the progression of cachexia effectively and promote quality of life.

The present systematic review and meta-analysis study evaluated the impact of early enteral nutrition (EN) on postoperative nutritional and immunological outcomes of gastric cancer (GC) patients. The databases of PubMed, Embase, Springer, and Cochrane library were searched till September 2016 to identify studies which evaluated the effects of EN compared with parenteral nutrition (PN) on postoperative immunological and nutritional status and hospitalization time in GC patients. Mean difference (MD) or standard mean difference (SMD) was calculated and I-square statistic test was used for heterogeneity analysis. The present systematic review and meta-analysis have consisted of seven trials, containing 835 GC patients. According to the result of meta-analysis, compared with PN, EN significantly resulted in more increase in the level of albumin [MD = 2.07 (0.49, 3.64)], prealbumin [MD = 9.41 (049, 33.55)], weight [MD = 1.52 (0.32, 2.72)], CD3+ [SMD = 1.96 (1.50, 2.43)], CD4+ [SMD = 2.45 (1.97, 2.93)], natural killers [MD = 5.80 (3.75, 7.85)], and also a decrease in the hospitalization time [MD=-2.39 (-2.74, -2.03)]. The results demonstrated that early administration of EN is more effective in improving postsurgical nutrition status and immune index in GC patients. So, based on these results, postoperative early administration of EN is recommended for GC patients where possible.

This cross-sectional study was aimed at determining whether certain pre-natal and natal conditions can predict specific dental anomalies. The conditions observed were: low birth-weight, preterm birth, pre-natal & natal complications. The dental anomalies observed were: enamel defects, total number of decayed, missing and filled teeth (total DMFT), disturbances in the tooth shape and disturbances in the number of teeth. Out of more than 2000 medical files of children aged 2-17 years old which were reviewed, 300 files met the selection criteria. Information recorded from the files included: age, gender, health status (the ASA physical status classification system by the American Society of Anesthesiologists), birth week, birth weight, total DMFT, hypomineralization, abnormal tooth shape, abnormal number of teeth and hypoplasia. Twenty one children out of 300 (7%) were born after a high-risk pregnancy, 25 children (8.3%) were born after high-risk birth, 20 children (6.7%) were born preterm - before week 37, and 29 children (9.7%) were born with a low birth weight (LBW) - 2500 grams or less. A relationship between a preterm birth and LBW to hypomineralization was found. And a relationship between a preterm birth and high-risk pregnancy to abnormal number of teeth was found. No relationship was found between birth (normal/high-risk) and the other parameters inspected. Preterm birth and LBW may predict hypomineralization in both primary and permanent dentitions. Furthermore, the study demonstrated that preterm birth and high-risk pregnancy may predict abnormal number of teeth in both dentitions.

Early oral nutrition (EON) has been shown to improve recovery of gastrointestinal function, length of stay and mortality after abdominal surgery; however, early oral nutrition often fails during the first week after surgery. Here, a multi-modal early oral nutrition program is introduced to promote recovery of gastrointestinal function and tolerance of oral nutrition. Consecutive patients scheduled for abdominal surgery were randomized to the multimodal EON group or a group receiving conventional care. The primary endpoint was the time of first defecation. The secondary endpoints were outcomes and the cost-effectiveness ratio in treating infectious complications. The rate of infectious-free patients was regarded as the index of effectiveness. One hundred seven patients were randomly assigned to groups. Baseline characteristics were similar for both groups. In intention-to-treat analysis, the success rate of oral nutrition during the first week after surgery in the multimodal EON group was 44 (83.0%) versus 31 (57.4%) in the conventional care group (P = 0.004). Time to first defecation, time to flatus, recovery time of bowel sounds, and prolonged postoperative ileus were all less in the multimodal EON group (P < 0.05). The median postoperative length of stay in the multimodal EON group was 8 days (6, 12) versus 10 days (7, 18) in the conventional care group (P < 0.001). The total cost of treatment and nutritional support were also less in the multi-modal early oral nutrition group (P < 0.001). The effectiveness was 84.9 and 79.9% in the multimodal EON and conventional care group, respectively (P = 0.475). However, the cost-effectiveness ratio was USD 537.6 (506.1, 589.3) and USD 637.8 (593.9, 710.3), respectively (P < 0.001). The multi-modal early oral nutrition program was an effective way to improve tolerance of oral nutrition during the first week after surgery, decrease the length of stay and improve cost-effectiveness after abdominal

Development rates vary among individuals, often as a result of direct competition for food. Survival of young might depend on their learning abilities, but it remains unclear whether learning abilities are affected by nutrition during development. The authors demonstrated that compared with controls, 1-year-old Western scrub jays (Aphelocoma californica) that experienced nutritional deficits during early posthatching development had smaller hippocampi with fewer neurons and performed worse in a cache recovery task and in a spatial version of an associative learning task. In contrast, performance of nutritionally deprived birds was similar to that of controls in 2 color versions of an associative learning task. These findings suggest that nutritional deficits during early development have long-term consequences for hippocampal structure and spatial memory, which, in turn, are likely to have a strong impact on animals' future fitness.

To evaluate energy and protein intake changes in early supplemental parenteral nutrition (PN) in trauma patients, and to assess its impact on clinical outcomes. Clinical results of patients receiving or not receiving additional PN during the first 7 days after injury were retrospectively analyzed, with a total of 195 patients classified into two groups: control group (n=105) and mixed nutrition group (n=90). The time of nutrition support, intakes of protein and energy within 14 days after trauma, and clinical outcomes were compared between two groups. The degree of injury was comparable between two groups with no significant differences in acute physiology and chronic health evaluation II score, injury severity score (ISS) and Glasgow coma score (GCS). Compared with the control group, the mixed nutrition group received parenteral nutritional support earlier (40.0±21.0 hours vs. 55.1±23.5 hours, P<0.01), with later beginning of enteral nutrition (EN, 75.2±54.5 hours vs. 55.1±23.5 hours, P<0.01) and lower rate of EN in 48 hours after admission [14.4% (13/90) vs. 43.8% (46/105), P<0.01]. The time of restoring oral diet was not different between the mixed nutrition group and control group (10.8±3.7 days vs. 11.4±3.6 days, P>0.05). The energy intake was significantly higher in the mixed nutrition group than in the control group in 3, 7, 14 days (3 days: 3981.6±2209.3 kJ vs. 2683.2±1414.9 kJ, 7 days: 5477.5±2008.4 kJ vs. 3619.1±1429.9 kJ, 14 days: 6250.2±2533.2 kJ vs. 5199.9±1972.7 kJ, P<0.05 or P<0.01). In both groups the protein intake was insufficient, and it was significantly lower in the mixed nutrition group than in the control group on day 3 (20.6±18.4 g vs. 26.5±13.8 g, P<0.05). The patients in the mixed nutrition group had longer hospital stay time (73.9±62.5 days vs. 50.9±33.3 days, P<0.01). The mortality rate of mixed nutrition group and control group was 4.4% (4/90) and 3.8% (4/105) respectively, the rate of infection and acute respiratory

Early Child Development and Nutrition: A Review of the Benefits and Challenges of Implementing Integrated Interventions1234

2016-01-01

Poor nutrition (substandard diet quantity and/or quality resulting in under- or overnutrition) and the lack of early learning opportunities contribute to the loss of developmental potential and life-long health and economic disparities among millions of children aged <5 y. Single-sector interventions representing either early child development (ECD) or nutrition have been linked to positive child development and/or nutritional status, and recommendations currently advocate for the development and testing of integrated interventions. We reviewed the theoretical and practical benefits and challenges of implementing integrated nutrition and ECD interventions along with the evidence for best practice and benefit-cost and concluded that the strong theoretical rationale for integration is more nuanced than the questions that the published empirical evidence have addressed. For example, further research is needed to 1) answer questions related to how integrated messaging influences caregiver characteristics such as well-being, knowledge, and behavior and how these influence early child nutrition and development outcomes; 2) understand population and nutritional contexts in which integrated interventions are beneficial; and 3) explore how varying implementation processes influence the efficacy, uptake, and cost-benefit of integrated nutrition and ECD interventions.

Evaluation of the Edinburgh Post Natal Depression Scale using Rasch analysis

Pallant, Julie F; Miller, Renée L; Tennant, Alan

2006-01-01

Background The Edinburgh Postnatal Depression Scale (EPDS) is a 10 item self-rating post-natal depression scale which has seen widespread use in epidemiological and clinical studies. Concern has been raised over the validity of the EPDS as a single summed scale, with suggestions that it measures two separate aspects, one of depressive feelings, the other of anxiety. Methods As part of a larger cross-sectional study conducted in Melbourne, Australia, a community sample (324 women, ranging in age from 18 to 44 years: mean = 32 yrs, SD = 4.6), was obtained by inviting primiparous women to participate voluntarily in this study. Data from the EPDS were fitted to the Rasch measurement model and tested for appropriate category ordering, for item bias through Differential Item Functioning (DIF) analysis, and for unidimensionality through tests of the assumption of local independence. Results Rasch analysis of the data from the ten item scale initially demonstrated a lack of fit to the model with a significant Item-Trait Interaction total chi-square (chi Square = 82.8, df = 40; p < .001). Removal of two items (items 7 and 8) resulted in a non-significant Item-Trait Interaction total chi-square with a residual mean value for items of -0.467 with a standard deviation of 0.850, showing fit to the model. No DIF existed in the final 8-item scale (EPDS-8) and all items showed fit to model expectations. Principal Components Analysis of the residuals supported the local independence assumption, and unidimensionality of the revised EPDS-8 scale. Revised cut points were identified for EPDS-8 to maintain the case identification of the original scale. Conclusion The results of this study suggest that EPDS, in its original 10 item form, is not a viable scale for the unidimensional measurement of depression. Rasch analysis suggests that a revised eight item version (EPDS-8) would provide a more psychometrically robust scale. The revised cut points of 7/8 and 9/10 for the EPDS-8 show high

Early nutrition and health: short- and long-term outcomes.

Maternal diet, nutritional status during pregnancy, and the early diet of the offspring play an important role in later health. The short- and long-term outcomes of early nutrition have been extensively studied in recent decades. One of the most commonly investigated nutritional interventions is breastfeeding, which is associated with a number of positive short- and long-term outcomes. A short-term effect of breastfeeding is reduced morbidity and mortality in children from poor living conditions and in preterm infants. Breastfeeding is associated with better cognitive development and also has a long-term protective effect on obesity risk, prevalence of type 2 diabetes, and a lowering effect on blood pressure. Selected nutrients have undergone extensive investigation to show their role in disease prevention or improved development, e.g. protein intake in infancy seems to be associated with a later risk of obesity or docosahexaenoic acid supplementation has a positive impact on cognitive function. Another consideration is the fast catch-up growth in small for gestational age infants as an important factor associated with adult risk of cardiovascular problems. On the other hand, high protein and energy intake seems to be positively associated with some indicators of cognitive development. Most of the evidence comes from observational studies that cannot exclude potential confounders. Animal studies demonstrate causality but should not be directly extrapolated to humans. The number of randomized controlled studies is increasing but long-term follow-ups are necessary to obtain convincing results. The majority of these trials compare different infant formula compositions and macro- or micronutrient supplementation. One of the major questions is to define a critical (or opportunity) window and a mechanism of nutritional influence on several health outcomes. Copyright © 2013 S. Karger AG, Basel.

Background Extensive neuromotor development occurs early in human life, but the time that a brain injury occurs during development has not been rigorously studied when quantifying motor impairments. Objective This study investigated the impact of timing of brain injury on magnitude and distribution of weakness in the paretic arm of individuals with childhood-onset hemiparesis. Methods Twenty-four individuals with hemiparesis were divided into time periods of injury before birth (PRE-natal, n=8), around the time of birth (PERI-natal, n=8) or after 6 months of age (POST-natal, n=8). They, along with 8 typically developing peers, participated in maximal isometric shoulder, elbow, wrist, and finger torque generation tasks using a multiple degree-of-freedom load cell to quantify torques in 10 directions. A mixed model ANOVA was used to determine the effect of group and task on a calculated relative weakness ratio between arms. Results There was a significant effect of both time of injury group (p<0.001) and joint torque direction (p<0.001) on the relative weakness of the paretic arm. Distal joints were more affected compared to proximal joints, especially in the POST-natal group. Conclusions The distribution of weakness provides evidence for the relative preservation of ipsilateral corticospinal motor pathways to the paretic limb in those individuals injured earlier, while those who sustained later injury may rely more on indirect ipsilateral cortico-bulbospinal projections during the generation of torques with the paretic arm.

This study investigated the impact of timing of brain injury on the magnitude and distribution of weakness in the paretic arm of individuals with childhood-onset hemiparesis. A total of 24 individuals with hemiparesis were divided into time periods of injury before birth (PRE-natal, n = 8), around the time of birth (PERI-natal, n = 8), or after 6 months of age (POST-natal, n = 8). They, along with 8 typically developing peers, participated in maximal isometric shoulder, elbow, wrist, and finger torque generation tasks using a multiple-degree-of-freedom load cell to quantify torques in 10 directions. A mixed-model ANOVA was used to determine the effect of group and task on a calculated relative weakness ratio between arms. There was a significant effect of both time of injury group (P < .001) and joint torque direction (P < .001) on the relative weakness of the paretic arm. Distal joints were more affected compared with proximal joints, especially in the POST-natal group. The distribution of weakness provides evidence for the relative preservation of ipsilateral corticospinal motor pathways to the paretic limb in those individuals injured earlier, whereas those who sustained later injury may rely more on indirect ipsilateral corticobulbospinal projections during the generation of torques with the paretic arm.

[Development of the pregnancy nutrition knowledge scale and its relationship with eating habits in pregnant women visiting community health center].

Kim, Hae Won

2009-02-01

This study was done to develop a pregnancy nutrition knowledge scale and to examine the relationships between pregnancy nutrition knowledge and eating habits in pregnant women. With convenient sampling, 189 pregnant women who used community health centers for their ante-natal care were recruited. Data were collected using a self administered questionnaire including items on pregnancy nutrition knowledge (18 items) developed by researcher and items on eating habits (14 items). Cronbach's alpha and exploratory factor analysis were examined to test reliability and construct validity of the scale. Pearson's correlation coefficients were used to identify the relationship between pregnancy nutrition knowledge and eating habits. Cronbach's alpha of 18 items was .80. In factor analysis using principal components, 6 factors explained 65% of the total variance. The level of pregnancy nutrition knowledge was not sufficient but correlations between pregnancy nutrition knowledge and some of eating habits were significant. Specifically, pregnancy nutrition knowledge was positively correlated with good eating habits and negatively with bad eating habits. The pregnancy nutrition knowledge scale developed in this study is acceptable for nutrition education led by nurses. Pregnancy nutrition knowledge and eating habits are considered as major variables for ante-natal nutrition education. In future studies, explorations are needed on dietary intake and physiological indices in pregnant women, comparison of women at risk with those not at risk, and development of nutritional education programs for pregnant women.

Little data are available on the relationship between indirect antibiotic exposure of the child in utero or during lactation and allergic diseases. On the other hand, several studies have been conducted on the association with direct post-natal antibiotic exposure, but the results are conflicting. The aim of this study was to investigate pre- and post-natal antibiotic exposure and the subsequent development of eczema, recurrent wheeze and atopic sensitization in children up to the age of 4 years. We conducted an aetiologic study in 773 children based on a prospective birth cohort project in which environmental and health information were collected using questionnaires. Antibiotic exposure was assessed as maternal antibiotic intake during pregnancy and during lactation and as medication intake of the child. The chronology of exposures and outcomes was taken into account during the data processing. At the age of 1 and 4 years, a blood sample was taken for the quantification of specific IgE. Prenatal antibiotic exposure was significantly positively associated with eczema, whereas no association was found with recurrent wheeze and atopic sensitization. We found a positive, although statistically not significant, association between antibiotic exposure through breastfeeding and recurrent wheeze. Neither eczema nor atopic sensitization was significantly associated with antibiotic exposure through breastfeeding. Finally, we observed a negative association between the use of antibiotics in the first year of life and eczema and atopic sensitization, and also between antibiotic use after the first year of life and recurrent wheeze, eczema and atopic sensitization. Indirect exposure to antibiotics (in utero and during lactation) increases the risk for allergic symptoms in children, while direct exposure to antibiotics appears to be protective. The biological mechanisms underlying these findings still need to be elucidated.

Nutritional status, lipid profile and HOMA-IR in post-liver transplant patients.

A high prevalence of overweight, obesity, diabetes and dyslipidemia has been reported following liver transplantation (LT). Although these conditions are known to induce an increased risk for cardiovascular events, which are among the major causes of death in post-LT patients, much debate remains in the literature regarding the applicability of different nutritional assessments methods to this population. To assess the nutritional status, lipid profile, homeostatic model assessment of insulin resistance (HOMA-IR) and dietary intake adequacy in the post-LT period. Cross-sectional study of patients after a maximum of 2 years post-LT, involving the assessment of body mass index (BMI), percent weight loss, arm (AC) and arm muscle circumference (AMC), triceps skinfold (TSF), neck (NC) and waist (WC) circumference, lipid profile, HOMA-IR and percent adequacy of dietary intake. In the group of 36 patients, 61.1% were male, mean age 53.2 years (± 10.6). Severe weight loss was noted in 66.7% of patients. Most individuals were eutrophic according to BMI, AC and AMC, while TSF showed malnutrition, NC demonstrated overweight and WC showed metabolic risk. Dyslipidemia was diagnosed in 87.5% of patients, and insulin resistance in 57% of the patients. Most patients had adequate dietary intake, although the time since transplant was positively correlated with AC (r = 0.353; p = 0.035) and negatively correlated with vitamin A intake (r = - 0.382; p = 0.022), with the caloric adequacy (r = -0.338; p = 0.044) and vitamin A adequacy (r = -0.382; p = 0.021). Although anthropometry provided somewhat variable nutritional diagnoses, when combined with biochemical tests, findings showed the prevalence of cardiovascular risk. As such, patients should be provided with transdisciplinary assistance, and strategies should be developed so as to reduce the risk factors recorded in this population.

Facial ontogeny in Neanderthals and modern humans

PubMed Central

Bastir, Markus; O'Higgins, Paul; Rosas, Antonio

2007-01-01

One hundred and fifty years after the discovery of Neanderthals, it is held that this morphologically and genetically distinct human species does not differ from modern Homo sapiens in its craniofacial ontogenetic trajectory after the early post-natal period. This is striking given the evident morphological differences between these species, since it implies that all of the major differences are established by the early post-natal period and carried into adulthood through identical trajectories, despite the extent to which mechanical and spatial factors are thought to influence craniofacial ontogeny. Here, we present statistical and morphological analyses demonstrating that the spatio-temporal processes responsible for craniofacial ontogenetic transformations differ. The findings emphasize that pre-natal as well as post-natal ontogeny are both important in establishing the cranial morphological differences between adult Neanderthals and modern humans.

Cerebrospinal fluid (CSF) hypovolemia is a common neurosurgical condition, which may be spontaneous or iatrogenic. At our institution, a substantial number of the reported cases of early post-operative CSF hypovolemia were identified to have unintentional or unrecognized post-operative continuous excessive CSF leakage. Cases who presented with post-operative CSF hypovolemia several days after uneventful intracranial surgeries without continuous CSF leakage were rarely reported. A retrospective review of the medical records of these patients was performed to identify those patients who developed early post-operative CSF hypovolemia without the presence of post-operative continuous CSF leakage. A total of 7 patients, 5 of which were males, were identified in this retrospective study. They experienced CSF hypovolemia between days 1 and 7 after emergency or scheduled intracranial surgeries. Ventricular collapse, cisternal effacement and midline shift are the most common radiological observations. With early diagnosis and management, 4 of the patients achieved a Glasgow Outcome Scale (GOS) score of 5, 1 achieved a GOS score of 4 and the remaining 2 had a GOS score of 3. No mortality was noted in this series. Although rare in incidence, early post-operative CSF hypovolemia may occur without the existence of post-operative continuous CSF leakage. When the diagnosis of CSF hypovolemia is reached, factors that may exacerbate CSF compensation should be promptly terminated. Trendelenburg position and sufficient intravenous hydration are practical and effective managements, and CSF hypovolemia may thereby be reversed in a substantial number of patients.

Post-operative fatigue - a real phenomenon attributable to the metabolic effects of surgery on body nutritional stores.

Stock, S E; Clague, M B; Johnston, I D

1991-10-01

Ambulatory monitoring of activity was undertaken in 97 patients before and at intervals following surgery employing a lightweight recorder and sensors to monitor posture and movement over 24h periods. A subjective assessment of fatigue, anthropometric measurements and clinical details were noted prior to each recording. Results were assessed using multiple regression analysis. Few patients exhibited any subjective feeling of fatigue. However, objective assessment did show a reduction in activity, several of the changes correlating with factors related to surgical stress and post-operative nutritional depletion. Reduction in time standing was related to both weight change at 2 weeks (p < 0.005) and duration of surgery (p < 0.05). Increase in time spent lying correlated with muscle loss at 2 weeks (p < 0.005). Number of steps walked was only influenced by weight change at 2 weeks (p < 0.05). Reduction in post-operative mobility may be related to the metabolic consequences of the surgery and its effects on depletion of nutritional stores. Manipulation of the response and aggressive nutritional support might well reduce post-operative fatigue.

Pregnant and post-partum women require increased nutrient intake and optimal cognition, which depends on adequate nutrition, to enable reasoning and learning for caregiving. We aimed to assess (a) differences in maternal cognition and caregiving between women in Malawi who received different nutritional supplements, (b) 14 effect modifiers, and (c) associations of cognition and caregiving with biomarkers of iron, Vitamin A, B-vitamin, and fatty acid status. In a randomized controlled trial (n = 869), pregnant women daily received either multiple micronutrients (MMN), 20 g/day lipid-based nutrient supplements (LNS), or a control iron/folic acid (IFA) tablet. After delivery, supplementation continued in the MMN and LNS arms, and the IFA control group received placebo until 6 months post-partum, when cognition (n = 712), caregiving behaviour (n = 669), and biomarkers of nutritional status (n = 283) were assessed. In the full group, only one difference was significant: the IFA arm scored 0.22 SD (95% CI [0.01, 0.39], p = .03) higher than the LNS arm in mental rotation. Among subgroups of women with baseline low hemoglobin, poor iron status, or malaria, those who received LNS scored 0.4 to 0.7 SD higher than the IFA arm in verbal fluency. Breastmilk docosahexaenoic acid and Vitamin B12 concentrations were positively associated with verbal fluency and digit span forward (adjusting for covariates ps < .05). In this population in Malawi, maternal supplementation with MMN or LNS did not positively affect maternal cognition or caregiving. Maternal docosahexaenoic acid and B12 status may be important for post-partum attention and executive function. © 2017 The Authors. Maternal and Child Nutrition Published by John Wiley & Sons, Ltd.

The role of early life nutrition in programming of reproductive function.

Chadio, S; Kotsampasi, B

2014-02-01

Accumulating evidence suggest that the concept of programming can also be applied to reproductive development and function, representing an ever expanding research area. Recently issues such as peri- or even preconceptional nutrition, transgenerational effects and underlying mechanisms have received considerable attention. The present chapter presents the existed evidence and reviews the available data from numerous animal and human studies on the effects of early life nutritional environment on adult reproductive function. Specific outcomes depend on the severity, duration and stage of development when nutritional perturbations are imposed, while sex-specific effects are also manifested. Apart from undernutrition, effects of relative overnutrition as well as the complex interactions between pre- and postnatal nutrition is of high importance, especially in the context of our days obesity epidemic. Mechanisms underlying reproductive programming are yet unclear, but may include a role for epigenetic modifications. Epigenetic modulation of critical genes involved in the control of reproductive function and potential intergenerational effects represent an exciting area of interdisciplinary research toward the development of new nutritional approaches during pre- and postnatal periods to ensure reproductive health in later life.

Early postoperative enteral nutrition (EN) after esophagectomy in esophageal cancer patient has been reported to be correlated with a better rehabilitation than parenteral nutrition (PN). However, a robust conclusion has not been achieved. Therefore, we performed a meta-analysis to compare the postoperative EN and PN in patients with esophageal cancer undergoing esophagectomy. Three electronic databases were searched for eligible studies to be included in the meta-analysis. The summary relative risk/weighted mean difference (RR/WMD) estimates and corresponding 95% confidence interval (CI) were calculated using fixed- and random-effects models. Ten studies met the inclusion criteria. The analysis demonstrated that the early postoperative EN could significantly decrease the pulmonary complications (RR = 0.37, 95% CI = 0.22-0.62, P = 0.00, test for heterogeneity: I(2) = 0.0%, P = 0.89) and anastomotic leakage (RR = 0.46, 95% CI = 0.22-0.96, P = 0.04, test for heterogeneity: I(2) = 0.0%, P = 0.66) compared with PN. On the eighth postoperative day, the EN group had a higher levels of albumin (WMD = 1.84, 95% CI = 0.47-3.21, P = 0.01, test for heterogeneity: I(2) = 84.5%, P = 0.00) and prealbumin (WMD = 12.96, 95% CI = 3.63-22.29, P = 0.01, test for heterogeneity: I(2) = 0.0%, P = 0.63) compared with the PN group. However, there was no difference in digestive complications between these two approaches (RR = 1.30, 95% CI = 0.79-2.13, P = 0.30, test for heterogeneity: I(2) = 0.0%, P = 0.97). For patients with esophageal cancer following esophagectomy, the early postoperative EN support could decrease the morbidity of severe complications, such as pulmonary complications and anastomotic leakage, and maintain patients at a better nutritional status than parenteral nutrion support. © 2015 International Society for Diseases of the Esophagus.

There is growing evidence of the effectiveness of early childhood interventions to improve the growth and development of children. Although, historically, nutrition and stimulation interventions may have been delivered separately, they are increasingly being tested as a package of early childhood interventions that synergistically improve outcomes over the life course. However, implementation at scale is seldom possible without first considering the relative cost and cost-effectiveness of these interventions. An evidence gap in this area may deter large-scale implementation, particularly in low- and middle-income countries. We conduct a literature review to establish what is known about the cost-effectiveness of early childhood nutrition and development interventions. A set of predefined search terms and exclusion criteria standardized the search across five databases. The search identified 15 relevant articles. Of these, nine were from studies set in high-income countries and six in low- and middle-income countries. The articles either calculated the cost-effectiveness of nutrition-specific interventions (n = 8) aimed at improving child growth, or parenting interventions (stimulation) to improve early childhood development (n = 7). No articles estimated the cost-effectiveness of combined interventions. Comparing results within nutrition or stimulation interventions, or between nutrition and stimulation interventions was largely prevented by the variety of outcome measures used in these analyses. This article highlights the need for further evidence relevant to low- and middle-income countries. To facilitate comparison of cost-effectiveness between studies, and between contexts where appropriate, a move towards a common outcome measure such as the cost per disability-adjusted life years averted is advocated. Finally, given the increasing number of combined nutrition and stimulation interventions being tested, there is a significant need for evidence of cost

In the present study, we evaluated the relationship between nutritional status, disease stage and quality of life (QoL) in 100 patients recently diagnosed with gastric carcinoma. The patients' nutritional status was investigated with anthropometric, biochemical, inflammatory and functional variables; and we also evaluated the nutritional risk with the Nutritional Risk Screening 2002. Oncological staging was standard. QoL was evaluated using the Functional Assessment of Anorexia/Cachexia Therapy questionnaire. The statistical correlation between nutritional risk score (NRS) and oncological characteristics or QoL was evaluated using both univariable and multivariable analyses. Weight loss and reduction of food intake were the most frequent pathological nutritional indicators, while biochemical, inflammatory and functional variables were in the normal range. According to NRS, thirty-six patients were malnourished or at risk for malnutrition. Patients with NRS ≥ 3 presented a significantly greater percentage of stage IV gastric cancer and pathological values of C-reactive protein, while no correlation was found with the site of tumour. NRS was negatively associated with QoL (P < 0·001) and this relation was independent from oncological and inflammatory variables as confirmed by multivariable analysis. In the present study, we found that in patients with gastric cancer malnutrition is frequent at diagnosis and this is likely due to reduction in food intake. Moreover, NRS is directly correlated with tumour stage and inversely correlated with QoL, which makes it a useful tool to identify patients in need of an early nutritional intervention during oncological treatments.

Early life mortality and height in Indian states

PubMed Central

Coffey, Diane

2014-01-01

Height is a marker for health, cognitive ability and economic productivity. Recent research on the determinants of height suggests that postneonatal mortality predicts height because it is a measure of the early life disease environment to which a cohort is exposed. This article advances the literature on the determinants of height by examining the role of early life mortality, including neonatal mortality, in India, a large developing country with a very short population. It uses state level variation in neonatal mortality, postneonatal mortality, and pre-adult mortality to predict the heights of adults born between 1970 and 1983, and neonatal and postneonatal mortality to predict the heights of children born between 1995 and 2005. In contrast to what is found in the literature on developed countries, I find that state level variation in neonatal mortality is a strong predictor of adult and child heights. This may be due to state level variation in, and overall poor levels of, pre-natal nutrition in India. PMID:25499239

The current knowledge about early-life nutrition and environmental factors that affect the interaction between the symbiotic microbiota and the host immune system has demonstrated novel regulatory target for treating allergic diseases, autoimmune disorders and metabolic syndrome. Various kinds of food nutrients (such as dietary fiber, starch, polyphenols and proteins) can provide energy resources for both intestinal microbiota and the host. The indigestible food components are fermented by the indigenous gut microbiota to produce diverse metabolites, including short-chain fatty acids, bile acids and trimethylamine-N-oxide, which can regulate the host metabolized physiology, immunity homeostasis and health state. Therefore it is commonly believed early-life perturbation of the microbial community structure and the dietary nutrition interference on the child mucosal immunity contribute to the whole life susceptibility to chronic diseases. In all, the combined interrelationship between food ingredients nutrition, intestinal microbiota configurations and host system immunity provides new therapeutic targets to treat various kinds of pathogenic inflammations and chronic diseases.

Previous analyses have shown that a post-discharge individualized nutritional intervention had positive effects on body weight, lean body mass, functional limitations and fall incidents in malnourished older patients. However, the impact of this intervention on survival has not yet been studied. The objective of this randomized controlled study was to examine the effect of a post-discharge individualized nutritional intervention on survival in malnourished older patients. Malnourished older patients, aged ≥ 60 years, were randomized during hospitalization to a three-months post-discharge nutritional intervention group (protein and energy enriched diet, oral nutritional supplements, vitamin D3/calcium supplement and telephone counseling by a dietitian) or to a usual care regimen (control group). Survival data were collected 4 years after enrollment. Survival analyses were performed using intention-to-treat analysis by Log-rank tests and Cox regression adjusted for confounders. The study population consisted of 94 men (45%) and 116 women with a mean age of 74.5 (SD 9.5) years. There were no statistically significant differences in baseline characteristics. Survival data was available in 208 out of 210 patients. After 1 and 4 years of follow-up, survival rates were respectively 66% and 29% in the intervention group (n=104) and 73% and 30% in the control group (n=104). There were no statistically significant differences in survival between the two groups 1 year (HR= 0.933, 95% CI=0.675-1.289) and 4 years after enrollment (HR=0.928, 95% CI=0.671-1.283). The current study failed to show an effect of a three-months post-discharge multi-component nutritional intervention in malnourished older patients on long-term survival, despite the positive effects on short-term outcome such as functional limitations and falls.

Nearly all countries in the world today are burdened with malnutrition, manifesting as undernutrition, micronutrient deficiencies, and/or overweight and obesity. Despite some progress, efforts to alleviate malnutrition are hampered by a shortage in number, skills, and geographic coverage, of a workforce for nutrition. Here, we report the findings of the Castel Gandolfo workshop, a convening of experts from diverse fields in March 2014 to consider how to develop the capacity of a global cadre of nutrition professionals for the post-2015 development era. Workshop participants identified several requirements for developing a workforce for nutrition, including an ability to work as part of a multisectoral team; communication, advocacy, and leadership skills to engage decision makers; and a set of technical skills to address future challenges for nutrition. Other opportunities were highlighted that could immediately contribute to capacity development, including the creation of a consortium to link global North and South universities, online training modules for middle managers, and practical, hands-on experiences for frontline nutrition workers. Institutional and organizational support is needed to enable workshop recommendations on education and training to be effectively implemented and sustained. The findings from the Castel Gandolfo workshop can contribute to the delivery of successful nutrition-relevant actions in the face of mounting external pressures and informing and attaining the forthcoming Sustainable Development Goals.

Natal Host Plants Can Alter Herbivore Competition.

2016-01-01

Interspecific competition between herbivores is widely recognized as an important determinant of community structure. Although researchers have identified a number of factors capable of altering competitive interactions, few studies have addressed the influence of neighboring plant species. If adaptation to/ epigenetic effects of an herbivore's natal host plant alter its performance on other host plants, then interspecific herbivore interactions may play out differently in heterogeneous and homogenous plant communities. We tested wether the natal host plant of a whitefly population affected interactions between the Middle-east Asia Minor 1 (MEAM1) and Mediterranean (MED) cryptic species of the whitefly Bemisia tabaci by rearing the offspring of a cabbage-derived MEAM1 population and a poinsettia-derived MED population together on three different host plants: cotton, poinsettia, and cabbage. We found that MED dominated on poinsettia and that MEAM1 dominated on cabbage, results consistent with previous research. MED also dominated when reared with MEAM1 on cotton, however, a result at odds with multiple otherwise-similar studies that reared both species on the same natal plant. Our work provides evidence that natal plants affect competitive interactions on another plant species, and highlights the potential importance of neighboring plant species on herbivore community composition in agricultral systems.

If adaptation to/ epigenetic effects of an herbivore’s natal host plant alter its performance on other host plants, then interspecific herbivore interactions may play out differently in heterogeneous and homogenous plant communities. We tested wether the natal host plant of a whitefly population affected interactions between the Middle-east Asia Minor 1 (MEAM1) and Mediterranean (MED) cryptic species of the whitefly Bemisia tabaci by rearing the offspring of a cabbage-derived MEAM1 population and a poinsettia-derived MED population together on three different host plants: cotton, poinsettia, and cabbage. We found that MED dominated on poinsettia and that MEAM1 dominated on cabbage, results consistent with previous research. MED also dominated when reared with MEAM1 on cotton, however, a result at odds with multiple otherwise-similar studies that reared both species on the same natal plant. Our work provides evidence that natal plants affect competitive interactions on another plant species, and highlights the potential importance of neighboring plant species on herbivore community composition in agricultral systems.

We estimated natal and breeding philopatry and dispersal probabilities for a metapopulation of Black Brant (Branta bernicla nigricans) based on observations of marked birds at six breeding colonies in Alaska, 1986–1994. Both adult females and males exhibited high (>0.90) probability of philopatry to breeding colonies. Probability of natal philopatry was significantly higher for females than males. Natal dispersal of males was recorded between every pair of colonies, whereas natal dispersal of females was observed between only half of the colony pairs. We suggest that female-biased philopatry was the result of timing of pair formation and characteristics of the mating system of brant, rather than factors related to inbreeding avoidance or optimal discrepancy. Probability of natal philopatry of females increased with age but declined with year of banding. Age-related increase in natal philopatry was positively related to higher breeding probability of older females. Declines in natal philopatry with year of banding corresponded negatively to a period of increasing population density; therefore, local population density may influence the probability of nonbreeding and gene flow among colonies.

Sun Compass Orientation Helps Coral Reef Fish Larvae Return to Their Natal Reef

Reef fish sustain populations on isolated reefs and show genetic diversity between nearby reefs even though larvae of many species are swept away from the natal site during pelagic dispersal. Retention or recruitment to natal reefs requires orientation capabilities that enable larvae to find their way. Although olfactory and acoustically based orientation has been implicated in homing when larvae are in the reef’s vicinity, it is still unclear how they cope with greater distances. Here we show evidence for a sun compass mechanism that can bring the larvae to the vicinity of their natal reef. In a circular arena, pre-settlement larvae and early settlers (<24 hours) of the cardinal fish, Ostorhinchus doederleini, showed a strong SSE directional swimming response, which most likely has evolved to compensate for the locally prevailing large scale NNW current drift. When fish were clock-shifted 6 hours, they changed their orientation by ca. 180° as predicted by the tropical sun curve at One Tree Island, i.e. they used a time-compensated sun compass. Furthermore, the fish oriented most consistently at times of the day when the sun azimuth is easy to determine. Microsatellite markers showed that the larvae that had just arrived at One Tree Island genetically belonged to either the local reef population or to Fitzroy Reef located 12 kilometers to the SSE. The use of a sun compass adds a missing long-distance link to the hierarchy of other sensory abilities that can direct larvae to the region of origin, including their natal reef. Predominant local recruitment, in turn, can contribute to genetic isolation and potential speciation. PMID:23840396

Post-natal Depression (PND) is a depressive disorder that causes significant distress or impairment on different levels in the individual's life and their families. There is already evidence of the efficacy of psychological treatments for PND. We conducted a narrative review and researched the literature for identifying systematic reviews and studies for the best psychological treatments of PND, and examined what parameters made those treatments successful. We searched 4 electronic databases. We included reviews and randomised controlled clinical trials for our research. We excluded other types of studies such as case studies and cohort studies. We followed a specific search strategy with specific terms and a selection process. We identified risk of bias in reviews and studies, and identified their limitations. We synthesized the data based on particular information, including: name of the authors, location, research type, target, population, delivery, outcome measures, participants, control groups, types of intervention, components of treatments, providers, experimental conditions amongst others. We found 6 reviews and 15 studies which met our inclusion criteria focusing on Cognitive Behavioural Therapy (CBT) for PND. Among the main findings we found that CBT can be delivered on an individual basis or within a group. It can be effective in the short-term, or up to six months post-intervention. CBT can be delivered by professionals or experts, but can also be practiced by non-experts. We found 7 components of CBT, including psychoeducation, cognitive restructuring, and goal setting. We also researched whether virtual reality (VR) has ever been used for the treatment of PND, and found that it has not. From our review, we have concluded that CBT is an effective treatment for PND. We have explored the utility of VR as a possible therapeutic modality for PND and have decided to run a pilot feasibility study as a next step, which will act as the foundational guide for a

Institutional deprivation is multifaceted and includes adverse psychosocial and nutrition-related components. In this study we partitioned these risks in relation to cognitive impairment and mental ill health, and explored the mediating role of reduced head/brain size. There were 138 participants (61 males, 77 females) in the study. Participants were Romanian adoptees who had experienced at least 2 weeks of early institutional deprivation. The sample was stratified on the basis of duration of deprivation (high risk >6 mo in institutions) and sub-nutrition (i.e. 1.5 SD below UK age-related norms for weight at UK entry). UK children adopted before 6 months of age and a group of non-institutionally deprived Romanian children constituted the comparison groups. Duration of deprivation was associated with smaller head circumference, lowered IQ, and increased mental heath problems, independently of effects found for sub-nutrition on head circumference and IQ. The mediating role of head circumference was limited to either sub-nourished (IQ) or non-sub-nourished (inattention/overactivity and disinhibited attachment) subgroups. Many negative effects of early deprivation, including stunted brain growth, occur without sub-nutrition: psychosocial deprivation plays a major role in neurodevelopmental effects of deprivation. Further studies of functional and structural neuroanatomy following institutional deprivation are required to delineate the role of brain development in its effects.

Adequate and timely provision of nutritional support is a crucial component of care of the critically ill burn patient. The goal of this study was to assess a single center's consistency with Society of Critical Care Medicine/American Society for Parenteral and Enteral Nutrition (SCCM/ASPEN) guidelines for nutritional support in critically ill patients. Acutely burned patients >45kg in weight admitted to a regional burn center during a two-year period and who required 5 or more days of full enteral nutritional support were eligible for inclusion in this retrospective review. Specific outcomes evaluated include time from admission to feeding tube placement and enteral feeding initiation and percent of nutritional goal received within the first week of hospital stay. Descriptive statistics were used for all analyses. IRB approval was obtained. Thirty-seven patients were included in this retrospective review. Median age of patients was 44.9 years (IQR: 24.2-55.1), and median burn injury size was 30% (IQR: 19-47). Median time to feeding tube placement was 31.1h post admission (IQR: 23.6-50.2h), while median time to initiation of EN was 47.9h post admission (IQR: 32.4-59.9h). The median time required for patients to reach 60% of caloric goal was 3 days post-admission (IQR: 3-4.5). The median time for initiation of enteral nutrition was within the SCCM/ASPEN guidelines for initial nutrition in the critically ill patient. This project identified a 16h time lag between placement of enteral access and initiation of enteral nutrition. Development of a protocol for feeding tube placement and enteral nutrition management may optimize early nutritional support in the acutely injured burn patient.

Ficussur (Moraceae) is an indigenous medicinal plant with a wide distribution in Africa. In this study, the nutritional potential fruit of this indigenous plant to meet domestic food demands and reduce food insecurity in KwaZulu-Natal. South Africa, was investigated. The proximate composition and concentrations of metals in the edible fruits collected from eight different sites in KwaZulu-Natal were determined to assess for nutritional value and the concentrations of metals in the growth soil was determined to evaluate the impact of soil quality on elemental uptake. The fruits contained high levels of moisture (88.8%) and carbohydrates (65.6%). The concentrations of elements in the fruits were found to be in decreasing order of Ca>Mg >Fe >Zn>Cu >Mn> Se with low levels of toxic metals (As, Cd, Co and Pb). This study shows that the consumption of the fruits of F. sur can contribute positively to the nutritional needs of rural communities in South Africa for most essential nutrients without posing the risk of adverse health effects.

To investigate direct postoperative outcome and plasma amino acid concentrations in a study comparing early enteral nutrition versus early parenteral nutrition after major rectal surgery. Previously, it was shown that a low plasma glutamine concentration represents poor prognosis in ICU patients. A preplanned substudy of a previous prospective, randomized, open-label, single-centre study, comparing early enteral nutrition versus early parenteral nutrition in patients at high risk of postoperative ileus after surgery for locally advanced or locally recurrent rectal cancer. Early enteral nutrition reduced postoperative ileus, anastomotic leakage, and hospital stay. Tertiary referral centre for locally advanced and recurrent rectal cancer. A total of 123 patients with locally advanced or recurrent rectal carcinoma requiring major rectal surgery. Patients were randomized (ALEA web-based external randomization) preoperatively into two groups: early enteral nutrition (early enteral nutrition, intervention) by nasojejunal tube (n = 61) or early parenteral nutrition (early parenteral nutrition, control) by jugular vein catheter (n = 62). Eight hours after the surgical procedure artificial nutrition was started in hemodynamically stable patients, stimulating oral intake in both groups. Blood samples were collected to measure plasma glutamine, citrulline, and arginine concentrations using a validated ultra performance liquid chromatography-tandem mass spectrometric method. Baseline concentrations were comparable for both groups. Directly after rectal surgery, a decrease in plasma amino acids was observed. Plasma glutamine concentrations were higher in the parenteral group than in the enteral group on postoperative day 1 (p = 0.027) and day 5 (p = 0.008). Arginine concentrations were also significantly increased in the parenteral group at day 1 (p < 0.001) and day 5 (p = 0.001). Lower plasma glutamine and arginine concentrations were measured in the enteral group, whereas a

This study aimed to determine the effects of feeding an increased volume of high-fat milk during the early post-natal life on metabolite concentrations in the blood, the expression of key genes regulating intermediary metabolism in the skeletal muscles, and the rate of growth of Japanese Black cattle. All calves were fed a high-fat milk replacer (crude protein, 26%; crude fat, 25.5%; total dissolved nitrogen, 116%). Control calves (n = 4) were nursed with 500 g milk replacer until 3 months of age, whereas calves in the experimental group (n = 4) were nursed with 1800 g milk replacer until 3 months, and then the volume was gradually reduced until 5 months. Body weight was significantly higher in the experimental group than in the control group at 7 months. Plasma glucose concentrations were significantly lower in the experimental group. Expression of glucose-transporter-4 messenger RNA (mRNA) was lower, whereas that of glucose transporter 1, cluster of differentiation 36, and carnitine palmitoyltransferase-1b mRNA was significantly higher in the Longissimus thoracis of the experimental group. Nutritional status during early post-natal life appears to strongly influence the growth rate and glucose and lipid metabolism in Japanese Black cattle. © 2015 Japanese Society of Animal Science.

There is growing evidence of the effectiveness of early childhood interventions to improve the growth and development of children. Although, historically, nutrition and stimulation interventions may have been delivered separately, they are increasingly being tested as a package of early childhood interventions that synergistically improve outcomes over the life course. However, implementation at scale is seldom possible without first considering the relative cost and cost-effectiveness of these interventions. An evidence gap in this area may deter large-scale implementation, particularly in low- and middle-income countries. We conduct a literature review to establish what is known about the cost-effectiveness of early childhood nutrition and development interventions. A set of predefined search terms and exclusion criteria standardized the search across five databases. The search identified 15 relevant articles. Of these, nine were from studies set in high-income countries and six in low- and middle-income countries. The articles either calculated the cost-effectiveness of nutrition-specific interventions (n = 8) aimed at improving child growth, or parenting interventions (stimulation) to improve early childhood development (n = 7). No articles estimated the cost-effectiveness of combined interventions. Comparing results within nutrition or stimulation interventions, or between nutrition and stimulation interventions was largely prevented by the variety of outcome measures used in these analyses. This article highlights the need for further evidence relevant to low- and middle-income countries. To facilitate comparison of cost-effectiveness between studies, and between contexts where appropriate, a move towards a common outcome measure such as the cost per disability-adjusted life years averted is advocated. Finally, given the increasing number of combined nutrition and stimulation interventions being tested, there is a significant need for evidence of cost

Growing concern over the relation between out-of-home eating and overweight has triggered the use of point-of-purchase (POP) nutrition information when eating out of the home. In canteens that offer various unhealthy choices, the posting of POP nutrition information has the potential to improve meal choices and dietary intakes. The objective of this study was to increase the proportion of consumed meals that comply with recommendations for energy, saturated fat, sodium, and vegetable content by 5%. A one-group pretest-posttest design was used. A total of 224 customers of 2 university canteens completed a questionnaire used for consumer profiling and 3-d food records to assess their meal choices and nutrient intakes. The 12 best meal combinations received star ratings and descriptors for nutrients or food groups that did not comply. Reported meal choices in canteens and nutrient intakes did not improve after the intervention (P > 0.05). The nutritional profile of the meal choice, obtained from a qualitative and quantitative nutritional assessment of meals, mirrored the nutritional profile of all meals offered (P > 0.05) and not that of the recommended meals offered (P < 0.001). Meal choices were not compensated for later in the day (P > 0.05). The healthiest choices were made by participants with greater objective nutrition knowledge, stronger health and weight-control motives, and a greater openness to change meal choices at baseline (P < 0.05). The posting of nutrition information in university canteens did not effectively change meal choices and nutrient intakes. Despite the intervention, meal choices were largely determined by meals offered. Therefore, nutrition-information interventions in canteens may be more effective with a healthier meal supply. This trial was registered at clinicaltrials.gov as NCT01249508.

Gender-specific effects of early nutritional restriction on adult obesity risk: evidence from quasi-experimental studies.

PubMed

Robinson, Whitney R

2012-12-01

In countries undergoing nutrition transition and historically poor minority groups in wealthy countries, obesity tends to be more common in women than men. A potential contributor to this female excess of obesity is a mismatch between perinatal nutritional restriction and a later calorie-rich environment. Several epidemiologic and quasi-experimental studies support a gender-differential effect of early nutritional deprivation on adult obesity. The quasi-experimental studies are of particular interest because results of quasi-experimental studies are typically less vulnerable to confounding bias than observational studies. Four quasi-experimental studies-exploiting 20th century famines that occurred in Europe, Africa, and Asia-provide evidence that perinatal nutritional restriction followed by relative caloric abundance may increase adult obesity risk to a greater extent in women than men. If the findings are accurate and generalizable to contemporary food environments, they suggest that the female offspring of poor, or otherwise nutritionally restricted, women in rapidly developing and wealthy countries may be at particularly high risk of adult obesity. Research into gender-specific effects of early life nutritional deprivation and its interactions with later environmental exposures may provide insight into global gender differences in obesity prevalence.

Assessment of nutritional status in laparoscopic gastrectomy for gastric cancer.

Malnutrition is very common in gastric cancer patients and can be detected in up to 85% of patients with gastric cancer. Malnutrition is associated with increased morbidity and mortality, prolonged hospital stay, poor treatment tolerance, and lower survival rate. Malnutrition also has an impact on quality of life. The early detection of nutritional risk with appropriate nutritional care can significantly reduce patient's postoperative morbidity and mortality. Because there is no gold standard tool, appropriate tools should be selected and applied depending on one's institutional conditions. And, it is recommended that nutritional assessment should be achieved for every patient at pre/post-operative period.

Transgenerational transmission of a stress-coping phenotype programmed by early-life stress in the Japanese quail

An interesting aspect of developmental programming is the existence of transgenerational effects that influence offspring characteristics and performance later in life. These transgenerational effects have been hypothesized to allow individuals to cope better with predictable environmental fluctuations and thus facilitate adaptation to changing environments. Here, we test for the first time how early-life stress drives developmental programming and transgenerational effects of maternal exposure to early-life stress on several phenotypic traits in their offspring in a functionally relevant context using a fully factorial design. We manipulated pre- and/or post-natal stress in both Japanese quail mothers and offspring and examined the consequences for several stress-related traits in the offspring generation. We show that pre-natal stress experienced by the mother did not simply affect offspring phenotype but resulted in the inheritance of the same stress-coping traits in the offspring across all phenotypic levels that we investigated, shaping neuroendocrine, physiological and behavioural traits. This may serve mothers to better prepare their offspring to cope with later environments where the same stressors are experienced. PMID:28387355

To determine if a model of home-based dietetic care improves dietary intake and weight status in a specific group of older adults post-hospitalisation. The Department of Veterans' Affairs clients aged 65 years and over were recruited from hospitals in a regional area of New South Wales, Australia (n = 32 men, n = 36 women). Nutritional status was assessed at home at baseline (within two weeks post-discharge) and three months post-discharge using a diet history, a food frequency checklist and Mini Nutritional Assessment (MNA). Personalised dietary advice was provided by a single dietitian according to participants' nutritional status. Mean body weight improved significantly (P = 0.048), as well as mean MNA score (21.9 ± 3.5 vs 25.2 ± 3.1) (P < 0.001). Mean energy, protein and micronutrient intakes were adequate at baseline and three months, except for vitamin D. At three months, the underweight group (body mass index (BMI) < 23 kg/m 2 ) had significantly higher mean protein intake per body weight (1.7 ± 0.4 g/kg) compared to those who were a desirable weight (BMI 23-27 kg/m 2 ) (1.4 ± 0.3 g/kg) or overweight (BMI>27 kg/m 2 ) (1.1 ± 0.3 g/kg) peers (P < 0.001). There was significant improvement in energy intake contributed from oral nutrition supplements (+95.5 ± 388.2 kJ/day) and milk (+259.6 ± 659.8 kJ/day). Dietetic intervention improved nutritional status 3 months after hospital discharge in older adults living in the community. © 2016 Dietitians Association of Australia.

Synthetic glucocorticoids are used to treat inflammatory conditions in horses. In other pregnant animals, glucocorticoids are given to stimulate fetal maturation with long-term metabolic consequences for the offspring if given preterm. However, their metabolic effects during equine pregnancy remain unknown. Thus, this study investigated the metabolic effects of dexamethasone administration on pregnant pony mares and their foals after birth. Experimental study. A total of 3 doses of dexamethasone (200 μg/kg bwt i.m.) were given to 6 pony mares at 48 h intervals beginning at ≈270 days of pregnancy. Control saline injections were given to 5 mares using the same protocol. After fasting overnight, pancreatic β cell responses to exogenous glucose were measured in the mares before, during and after treatment. After birth, pancreatic β cell responses to exogenous glucose and arginine were measured in the foals at 2 and 12 weeks. In mares during treatment, dexamethasone but not saline increased basal insulin concentrations and prolonged the insulin response to exogenous glucose. Basal insulin and glucose concentrations still differed significantly between the 2 groups 72 h post treatment. Dexamethasone treatment significantly reduced placental area but had little effect on foal biometry at birth or subsequently. Foal β cell function at 2 weeks was unaffected by maternal treatment. However, by 12 weeks, pancreatic β cell sensitivity to arginine, but not glucose, was less in foals delivered by dexamethasone- than saline-treated mares. Dexamethasone administration induced changes in maternal insulin-glucose dynamics, indicative of insulin resistance and had subtle longer term effects on post natal β cell function of the foals. The programming effects of dexamethasone in horses may be mediated partially by altered maternal metabolism and placental growth. © 2016 EVJ Ltd.

Prenatal iron supplementation may improve pregnancy outcomes and decrease the risk of child mortality. However, little is known about the importance of post-natal maternal iron status for child health and survival, particularly in the context of HIV infection. We examined the association of maternal anaemia and hypochromic microcytosis, an erythrocyte morphology consistent with iron deficiency, with child health and survival in the first two to five years of life. Repeated measures of maternal anaemia and hypochromic microcytosis from 840 HIV-positive women enrolled in a clinical trial of vitamin supplementation were prospectively related to child mortality, HIV infection and CD4 T-cell count. Median duration of follow-up for the endpoints of child mortality, HIV infection and CD4 cell count was 58, 17 and 23 months, respectively. Maternal anaemia and hypochromic microcytosis were associated with greater risk of child mortality [hazard ratio (HR) for severe anaemia = 2.58, 95% confidence interval (CI): 1.66-4.01, P trend < 0.0001; HR for severe hypochromic microcytosis = 2.36, 95% CI: 1.27-4.38, P trend = 0.001]. Maternal anaemia was not significantly associated with greater risk of child HIV infection (HR for severe anaemia = 1.46, 95% CI: 0.91, 2.33, P trend = 0.08) but predicted lower CD4 T-cell counts among HIV-uninfected children (difference in CD4 T-cell count/µL for severe anaemia: -93, 95% CI: -204-17, P trend = 0.02). The potential child health risks associated with maternal anaemia and iron deficiency may not be limited to the prenatal period. Efforts to reduce maternal anaemia and iron deficiency during pregnancy may need to be expanded to include the post-partum period. © 2012 Blackwell Publishing Ltd.

Our trial INTACT (Intensive Nutrition in Acute Lung Injury Trial) was designed to compare the impact of feeding from acute lung injury (ALI) diagnosis to hospital discharge, an interval that, to our knowledge, has not yet been explored. It was stopped early because participants who were randomly assigned to energy intakes at nationally recommended amounts via intensive medical nutrition therapy experienced significantly higher mortality hazards than did those assigned to standard nutrition support care that provided energy at 55% of recommended concentrations. We assessed the influence of dose and timing of feeding on hospital mortality. Participants (n = 78) were dichotomized as died or discharged alive. Associations between the energy and protein received overall, early (days 1-7), and late (days ≥8) and the hazards of hospital mortality were evaluated between groups with multivariable analysis methods. Higher overall energy intake predicted significantly higher mortality (OR: 1.14, 95% CI: 1.02, 1.27). Among participants enrolled for ≥8 d (n = 66), higher early energy intake significantly increased the HR for mortality (HR: 1.17, 95% CI: 1.07, 1.28), whereas higher late energy intake was significantly protective (HR: 0.91, 95% CI: 0.83, 1.0). Results were similar for early but not late protein (grams per kilogram) exposure (early-exposure HR: 8.9, 95% CI: 2.3, 34.3; late-exposure HR: 0.15, 95% CI: 0.02, 1.1). Threshold analyses indicated early mean intakes ≥18 kcal/kg significantly increased subsequent mortality. Providing kilocalories per kilogram or grams of protein per kilogram early post-ALI diagnosis at recommended levels was associated with significantly higher hazards for mortality, whereas higher late energy intakes reduced mortality hazards. This time-varying effect violated the Cox proportionality assumption, indicating that feeding trials in similar populations should extend beyond 7 d and use time-varying statistical methods.

Infants born small-for-gestational-age (SGA) who develop post-natal weight catch-up are at risk for insulin resistance, central adiposity and cardiovascular disease in later life, even in the absence of overweight. In young (age 3-6 years) non-obese SGA children, we assessed arterial health (as judged by intima-media thickness [IMT]) and abdominal fat distribution (subcutaneous, visceral, preperitoneal and hepatic components by magnetic resonance imaging [MRI] and/or ultrasound [US]) besides a selection of endocrine markers. Comparisons of measures in SGA (n = 27) vs. appropriate-for-GA (AGA) children (n = 19) of similar height, weight and body mass index. Longitudinal outcomes (age 3-6 years) were carotid IMT (cIMT); fasting glucose, circulating insulin, IGF-I and high-molecular-weight (HMW) adiponectin; abdominal fat partitioning by US. Cross-sectional outcomes (age 6 years) were aortic IMT (aIMT) and abdominal fat partitioning by MRI. At 3 and 6 years, cIMT and IGF-I results were higher and HMW adiponectin lower in SGA than AGA children; at 6 years, SGA subjects had also a thicker aIMT and more pre-peritoneal and hepatic fat, and were less insulin sensitive (all P values between <0.05 and <0.0001). cIMT correlated positively with pre-peritoneal fat, particularly at 6 years. Post-SGA status and weight gain in early childhood (between 3 and 6 years) were independent predictors of cIMT at 6 years, explaining 48 % of its variance. SGA children aged 3-6 years were found to have a thicker intima- media and more pre-peritoneal and hepatic fat than AGA children of comparable size. © 2015 World Obesity.

War rape, natality and genocide.

2011-01-01

Feminist philosophy can make an important contribution to the field of genocide studies, and issues relating to gender and war are gaining new attention. In this article I trace legal and philosophical analyses of sexual violence against women in war. I analyze the strengths and limitations of the concept of social death—introduced into this field by Claudia Card—for understanding the genocidal features of war rape, and draw on the work of Hannah Arendt to understand the central harm of genocide as an assault on natality. The threat to natality posed by the harms of rape, forced pregnancy and forced maternity lie in the potential expulsion from the public world of certain groups—including women who are victims, members of the 'enemy' group, and children born of forced birth.

The Mesoproterozoic Natal Metamorphic Province of Kwazulu-Natal in South Africa is an assemblage of several tectonic units, including accreted oceanic island arcs, obducted oceanic crust and deformed basin material. The highly deformed Mfongosi Group occurs at the leading edge of collision (the Natal thrust front), against and directly overlying the southern margin of the Kaapvaal Craton. Structures within the Mfongosi Group record "local" D1 and D2 events, the first of which was "oblique obduction", with predominantly N- to NNE-verging thrusting ( D1). This was followed by sinistral transpression combined with vertical constriction, forming SW-plunging kink folds and SW-plunging prolate pillow basalts ( D2). The third and final event ( D3) was E-W to ESE-WNW extension in a post-thrusting phase, defined by fibrous antitaxial quartz-calcite veining. The westernmost portion of the Mfongosi Group, the Ngubevu area, shows significantly higher finite strains (up to Rf = 12) compared to central Mfongosi and eastern Nkandlha areas ( Rf = 1.5 and less), suggesting highly oblique, largely NE-directed initial collision. Deformation of the NTF in the context of nappe emplacement is constrained by 40Ar/ 39Ar dating of post-cataclastic nematoblastic/porphyroblastic hornblende of the Manyane amphibolite close to the thrust between the Tugela nappe and the Mfongosi Group in the Mfongosi area. Hornblende overgrew the products of low-temperature deformation during the "local" D1 and D2. A minimum age of 1171 ± 16 Ma (95% conf., including J-error; weighted by √MSWD; MSWD = 4.3) is obtained for the tectonic juxtaposition of the Tugela nappe against the southern portions of the "Mfongosi Basin". This "local" D1 and D2 of the Mfongosi Group pre-dates the regional "oblique D1" and "left-lateral D2" previously determined for the central and southern terranes of the Natal Metamorphic Province by other researchers.

The role of zinc in the nervous system is receiving increased attention. At a time when dietary fortification and supplementation have increased the amount of zinc being consumed, little work has been done on the effects of enhanced zinc on behavior. Both zinc and copper are essential trace minerals that are acquired from the diet; under normal conditions the body protects against zinc overload, but at excessive dosages, copper deficiency has been seen. In order to examine the effect of enhanced metal administration on learning and memory, Sprague Dawley rats were given water supplemented with 10ppm Zn, 10ppm Zn+0.25ppm Cu, or normal lab water, during pre- and post-natal development. Fear conditioning tests at 4months showed significantly higher freezing rates during contextual retention and extinction and cued extinction for rats drinking water supplemented with zinc, suggesting increased anxiety compared to controls raised on lab water. During the MWM task at 9months, zinc-enhanced rats had significantly longer latencies to reach the platform compared to controls. The addition of copper to the zinc supplemented water brought freezing and latency levels closer to that of controls. These data demonstrate the importance of maintaining appropriate intake of both metals simultaneously, and show that long-term supplementation with zinc may cause alterations in memory.

Early childhood caries is a persistent worldwide problem. The etiologic contribution of feeding practices has been less frequently investigated in prospective studies of young children. The Porto Alegre Early Life Nutrition and Health Study has followed a birth cohort of 715 mother-child pairs, recruited from municipal health centers, originally involved in a cluster-randomized controlled trial of healthcare worker training. The birth cohort links prospectively collected socio-demographic, infant feeding, and general and oral health information. To date, oral health data, including caries status and oral health-related quality of life, have been collected for 458 children at the age of 2-3 years. Studies are underway to investigate possible determinants and consequences of oral health among these children.

Trophic or full nutritional support?

PubMed

Arabi, Yaseen M; Al-Dorzi, Hasan M

2018-06-04

Full nutritional support during the acute phase of critical illness has traditionally been recommended to reduce catabolism and prevent malnutrition. Approaches to achieve full nutrition include early initiation of nutritional support, targeting full nutritional requirement as soon as possible and initiation of supplemental parenteral nutrition when enteral nutrition does not reach the target. Existing evidence supports early enteral nutrition over delayed enteral nutrition or early parenteral nutrition. Recent randomized controlled trials have demonstrated that permissive underfeeding or trophic feeding is associated with similar outcomes compared with full feeding in the acute phase of critical illness. In patients with refeeding syndrome, patients with high nutritional risk and patients with shock, early enteral nutrition targeting full nutritional targets may be associated with worse outcomes compared with less aggressive enteral nutrition strategy. A two-phase approach for nutritional support may more appropriately account for the physiologic changes during critical illness than one-phase approach. Further evidence is awaited for the optimal protein amount during critical illness and for feeding patients at high nutritional risk or with acute gastrointestinal injury.

To investigate the effect of early enteral nutrition (EEN) combined with parenteral nutritional support in patients undergoing pancreaticoduodenectomy (PD). From January 2006, all patients were given EEN combined with parenteral nutrition (PN) (EEN/PN group, n = 107), while patients prior to this date were given total parenteral nutrition (TPN) (TPN group, n = 67). Venous blood samples were obtained for a nutrition-associated assessment and liver function tests on the day before surgery and 6 d after surgery. The assessment of clinical outcome was based on postoperative complications. Follow-up for infectious and noninfectious complications was carried out for 30 d after hospital discharge. Readmission within 30 d after discharge was also recorded. Compared with the TPN group, a significant decrease in prealbumin (PAB) (P = 0.023) was seen in the EEN/PN group. Total bilirubin (TB), direct bilirubin (DB) and lactate dehydrogenase (LDH) were significantly decreased on day 6 in the EEN/PN group (P = 0.006, 0.004 and 0.032, respectively). The rate of grade I complications, grade II complications and the length of postoperative hospital stay in the EEN/PN group were significantly decreased (P = 0.036, 0.028 and 0.021, respectively), and no hospital mortality was observed in our study. Compared with the TPN group (58.2%), the rate of infectious complications in the EEN/PN group (39.3%) was significantly decreased (P = 0.042). Eleven cases of delayed gastric emptying were noted in the TPN group, and 6 cases in the EEN/PN group. The rate of delayed gastric emptying and hyperglycemia was significantly reduced in the EEN/PN group (P = 0.031 and P = 0.040, respectively). Early enteral combined with PN can greatly improve liver function, reduce infectious complications and delayed gastric emptying, and shorten postoperative hospital stay in patients undergoing PD.

Perioperative nutritional assessment is critically important to reflect nutritional management because liver transplantation (LTx) often is undertaken in patients with poor nutritional status. The aim of this study was to evaluate nutritional status, including the non-protein respiratory quotient (npRQ), resting energy expenditure (REE), nitrogen balance, and blood biochemical parameters in patients before and after LTx. Fourteen patients undergoing LTx and 10 healthy controls were enrolled in this study. The npRQ and REE were measured using indirect calorimetry before LTx and at 2, 3, and 4 wk after the procedure. Blood biochemistry and nitrogen balance calculated by 24-h urine collection were performed concurrently with indirect calorimetric measurement; the results were compared between the two groups. Before LTx, npRQ was significantly lower and serum non-esterified fatty acid levels were significantly higher in the patients than in the controls. Furthermore, a negative nitrogen balance was observed in the patients. These, however, improved significantly at 4 wk after LTx. REE did not significantly increase compared with the preoperative values in recipients. Blood biochemistry showed gradually increasing levels of serum cholinesterase and albumin. These failed to reach to normal levels by 4 wk post-transplant. The findings revealed that improvement of nutritional metabolism after LTx may require 4 wk. Additional nutritional strategies, therefore, may be needed to minimize catabolic state during the early post-transplant period. Adequate, individualized nutritional guidance before and after LTx should be performed in these patients. Copyright © 2015 Elsevier Inc. All rights reserved.

Effects of early enteral nutrition (EEN) or total parenteral nutrition (TPN) support on nutritional status and blood glucose in patients with gastric cancer complicated with diabetes mellitus after radical gastrectomy were investigated. One hundred and twenty-nine patients with gastric cancer complicated with diabetes mellitus type 2 admitted to the First People's Hospital of Jinan (Jinan, China), from June 2012 to June 2016 were selected into the study. According to different nutrition support pathways, these patients were randomly divided into the EEN group and the TPN group. The improvement of nutritional indexes, postoperative complications, gastrointestinal function recovery and perioperative blood glucose fluctuation were compared between the two groups. On the 4th day after operation, the improvement levels of total bilirubin (TBL), alanine aminotransferase (ALT), aspartate transaminase (AST), total protein (TP), prealbumin (PAB), hemoglobin (HGB) and weight (Wt) in the EEN group were significantly higher than those in the conventional group (P<0.05). There were no significant differences between the two groups on the 8th day after operation (P>0.05). No patients had complications in the EEN group, while a total of 29 patients in the TPN group suffered adverse reactions, indicating that the incidence rate of complications in the EEN group was significantly lower than that in the TPN group (P<0.05). The postoperative evacuation time was earlier, hospitalization time was shorter and cost of postoperative hospitalization was less in the EEN group than those in the TPN group, and the differences were statistically significant (P<0.05). The blood glucose fluctuation values at fasting and 2 h after a meal in the TPN group were higher than those in the EEN group within 8 days after operation, and the differences were statistically significant (χ 2 =13.219, P=0.002; χ 2 =20.527, P<0.001).

Parenteral nutrition in the critically ill.

Feeding guidelines have recommended early, full nutritional support in critically ill patients to prevent hypercatabolism and muscle weakness. Early enteral nutrition was suggested to be superior to early parenteral nutrition. When enteral nutrition fails to meet nutritional target, it was recommended to administer supplemental parenteral nutrition, albeit with a varying starting point. Sufficient amounts of amino acids were recommended, with addition of glutamine in subgroups. Recently, several large randomized controlled trials (RCTs) have yielded important new insights. This review summarizes recent evidence with regard to the indication, timing, and dosing of parenteral nutrition in critically ill patients. One large RCT revealed no difference between early enteral nutrition and early parenteral nutrition. Two large multicenter RCTs showed harm by early supplementation of insufficient enteral nutrition with parenteral nutrition, which could be explained by feeding-induced suppression of autophagy. Several RCTs found either no benefit or harm with a higher amino acid or caloric intake, as well as harm by administration of glutamine. Although unanswered questions remain, current evidence supports accepting low macronutrient intake during the acute phase of critical illness and does not support use of early parenteral nutrition. The timing when parenteral nutrition can be initiated safely and effectively is unclear.

To describe the impact of the global economic crisis on the nutritional status of children in China during and after the crisis. Data from 1990 to 2010 were sourced from the National Food and Nutrition Surveillance System. Approximately 16 000 children under 5 years old were selected using a stratified random cluster method from 40 surveillance sites. Anthropometric and hemoglobin measurements for children under 5 were conducted. Nutritional status was determined according to WHO child growth standards. Prevalence of underweight and stunting in children under 5 had a downward trend. Underweight prevalence was close to normal (less than 5%), with prevalence of stunting 12.6% in 2009 and 12.1% in 2010 in rural areas. Prevalence of stunting in infants under 6 months and 6-12 months old in poorer rural areas increased from 5.7%-9.1% and 6.7%-12.5%, respectively, in 2008-2009. This trend also continued post-crisis in 2010. Prevalence of stunting in children left behind by mothers was 20%-30% higher than in children the same age in general and poorer rural areas. Prevalence of anemia in children did not change in rural areas, but prevalence of anemia in all age groups increased in poorer rural areas, especially in children under 24 months old. Level reached 30%-40% in 2009, and fluctuated in 2010. The nutritional status of children under 5 was comparatively stable during and after the global economic crisis, attributable to the Chinese government's policy response. The nutritional status in poorer rural areas fluctuated in response to the economic crisis and, thus, relevant action and intervention must be taken immediately to help the most vulnerable population in poorer rural areas. A proper national nutritional strategy for children under 2 years old, including nutrition supplementation for pregnant women and in-home fortification for complementary feeding, should be initiated.

The aim of this study was to investigate the changes of nutritional intake and nutritional status and analyze the association between them during hematopoietic stem cell transplantation. This was a retrospective cross sectional study on 36 patients (9 Autologous transplantation group and 27 Allogeneic transplantation group) undergoing hematopoietic stem cell transplantation at The Catholic University of Korea, Seoul St. Mary's Hospital from May to August 2010. To assess oral intake and parenteral nutrition intake, 24-hour recall method and patient's charts review was performed. Nutritional status was measured with the scored patient-generated subjective global assessment (PG-SGA). The subjects consisted of 6 (66.7%) males and 3 (33.3%) females in the autologous transplantation group (auto), 12 (44.4%) males and 15 (55.6%) females in the allogeneic transplantation group (allo). The mean age was 40.9 ± 13.6 years (auto) and 37.8 ± 11.0 years (allo). The average hospitalized period was 25.2 ± 3.5 days (auto) and 31.6 ± 6.6 days (allo), which were significant different (p < 0.05). Nutritional intake was lowest at Post+1wk in two groups. In addition, calorie intake by oral diet to recommended intake at Post+2wk was low (20.8% auto and 20.5% allo) but there were no significant differences in change of nutritional intake over time (Admission, Pre-1day, Post+1wk, Post+2wk) between auto group and allo group by repeated measures ANOVA test. The result of nutritional assessment through PG-SGA was significantly different at Pre-1day only (p < 0.01). There was a significant negative correlation between the nutritional status during Post+2wk and the oral calorie/protein intake to recommended amount measured during Post+1wk and Post+2wk (p < 0.01). These results could be used to establish evidence-based nutritional care guidelines for patients during hematopoietic stem cell transplantation. PMID:23430590

Early Nutrition as a Major Determinant of 'Immune Health': Implications for Allergy, Obesity and Other Noncommunicable Diseases.

Prescott, Susan L

2016-01-01

Early-life nutritional exposures are significant determinants of the development and future health of all organ systems. The dramatic rise in infant immune diseases, most notably allergy, indicates the specific vulnerability of the immune system to early environmental changes. Dietary changes are at the center of the emerging epigenetic paradigms that underpin the rise in many modern inflammatory and metabolic diseases. There is growing evidence that exposures in pregnancy and the early postnatal period can modify gene expression and disease susceptibility. Although modern dietary changes are complex and involve changing patterns of many nutrients, there is also interest in the developmental effects of specific nutrients. Oligosaccharides (soluble fiber), antioxidants, polyunsaturated fatty acids, folate and other vitamins have documented effects on immune function as well as metabolism. Some have also been implicated in modified risk of allergic diseases in observational studies. Intervention studies are largely limited to trials with polyunsaturated fatty acids and oligosaccharides, showing preliminary but yet unconfirmed benefits in allergy prevention. Understanding how environmental influences disrupt the finely balanced development of immune and metabolic programming is of critical importance. Diet-sensitive pathways are likely to be crucial in these processes. While an epigenetic mechanism provides a strong explanation of how nutritional exposures can affect fetal gene expression and subsequent disease risk, other diet-induced tissue compositional changes may also contribute directly to altered immune and metabolic function--including diet-induced changes in the microbiome. A better understanding of nutritional programming of immune health, nutritional epigenetics and the biological processes sensitive to nutritional exposures early in life may lead to dietary strategies that provide more tolerogenic conditions during early immune programming and reduce the

Multiple trauma is associated with altered metabolism, wasting of the lean body mass and compromised wound healing. Nutritional support is one way to improve the condition of these critically ill patients. We performed a prospective randomized study on the effect of early nutritional support in severely injured patients admitted to the Division of Traumatic Surgery, Siriraj Hospital between June 1992 and January 1994. Thirty-eight severe traumatic patients with ISS between 20-40 were randomly divided into control and study group. The 17 patients in the control group were treated in the conventional method with administration of hypo caloric intravenous regimen and supplement with oral diet as soon as the bowel function was returned. The 21 patients of the study group were fed either by enteral or parenteral feeding or both with an appropriate caloric and protein requirement as soon as hemodynamic status was stabilized. We found the study group had a lower mortality rate, a lower complication rate, a shorter period of ICU stay, and an earlier weaning from the ventilator than the control group. The study group also lost less weight than the control group. Nitrogen balance in the study group was significantly lower than the control group.

We retrospectively examined esophageal cancer patients who received enteral nutrition (EN) to clarify the validity of early EN compared with delayed EN. A total of 103 patients who underwent transthoracic esophagectomy with three-field lymphadenectomy for esophageal cancer were entered. Patients were divided into two groups; Group E received EN within postoperative day 3, and Group L received EN after postoperative day 3. The clinical factors such as days for first fecal passage, the dose of postoperative albumin infusion, differences of serum albumin value between pre- and postoperation, duration of systematic inflammatory response syndrome (SIRS), incidence of postoperative infectious complication, and use of total parenteral nutrition (TPN) were compared between the groups. The statistical analyses were performed using Mann-Whitney U test and Chi square test. The statistical significance was defined as p < 0.05. Group E showed fewer days for the first fecal passage (p < 0.01), lesser dose of postoperative albumin infusion (p < 0.01), less use of TPN (p < 0.01), and shorter duration of SIRS (p < 0.01). However, there was no significant difference in postoperative complications between the two groups. Early EN started within 3 days after esophagectomy. It is safe and valid for reduction of albumin infusion and TPN, for promoting early recovery of intestinal movement, and for early recovery from systemic inflammation. PMID:24067386

White-faced capuchin males disperse from their natal group at around 4.5 years of age, but there is much variation in dispersal timing: our youngest confirmed disperser was 19 months and the oldest 11 years old. In this study, we investigate possible factors influencing dispersal decisions in this species. Between 1983 and 2010, 64 males were born into three study groups in Santa Rosa National Park, Area de Conservación Guanacaste, and Costa Rica. As of August 2010, 21 died or were presumed dead (<14 months), 13 remained natal residents, and 30 were presumed dispersers. We used backward logistic regression to identify proximate factors that predict the occurrence of male natal dispersal. The occurrence of a takeover (significant positive association) and group size (nonsignificant negative association) were included in the model. Male age, number of maternal brothers, and number of adult males were not significant predictors of natal dispersal. The resultant model correctly classified 97% of dispersed and 89% of resident natal males, for an overall success rate of 95%. The occurrence of a group takeover was the strongest predictor of male dispersal, with natal males being 18.7 times more likely to disperse in the context of a group takeover than during peaceful times. A linear regression model showed that the tenure length of a male's probable father influences the age of natal dispersal, explaining 15% of the observed variation in age. However, when our oldest disperser was removed (an outlier) this effect disappeared. Collectively, these results indicate that group instability, as evidenced by the occurrence of a takeover, shorter tenure length of a natal male's father, and smaller group size, triggers natal dispersal in this species while the converse leads to a delay. These data add to our growing evidence of the enormous impact that takeovers have on the behavioral ecology of this species. © 2011 Wiley Periodicals, Inc.

Evidence linking long-term exposure to outdoor air pollution with allergic rhinitis (AR) in children is scare, and the role of components of air pollution and timing of exposure remains unclear. To assess the association of pre- and post-natal exposure to air pollution with life-time prevalence of AR in preschool children. We conducted a cohort study of 2598 children aged 3-6 years in Changsha, China. The lifetime prevalence of AR was assessed by a questionnaire administered by parents. Children's exposures to dioxide nitrogen (NO 2 ), sulfur dioxide (SO 2 ) and particulate matter with an aerodynamic diameter ≤ 10 μm (PM 10 ) during different pre- and post-natal timing windows were estimated using the measured concentrations at monitoring stations. The odds ratio (OR) and 95% confidence interval (CI) of childhood AR for exposure to different air pollutants during different timing windows were assessed by logistic regression model in terms of an interquartile range (IQR) increase in exposure level. Life-time prevalence of AR in preschool children (7.3%) was associated with both pre- and post-natal exposure to traffic-related air pollution (TRAP), but only significant during the third trimester of pregnancy with adjusted OR = 1.40 (95% CI: 1.08-1.82) for a 15 μg/m 3 increase in NO 2 and during the first-year of life with adjusted OR = 1.36 (95% CI: 1.03-1.78) and 1.54 (95% CI: 1.07-2.21) respectively for 11 and 12 μg/m 3 increase in NO 2 and PM 10 . The association of early life exposure to TRAP with childhood AR was robust by adjusting for other air pollutants and timing windows. Sensitivity analysis indicated that the association was higher in the children who are male, young, with genetic predisposition by parental atopy, and living in damp houses. Early life exposure to traffic-related air pollutant during pregnancy and first-year of life may contribute to childhood AR. Copyright © 2016 Elsevier Ltd. All rights reserved.

Early nutritional support is an essential component of burn care to prevent ileus, stress ulceration, and the effects of hypermetabolism. The American Burn Association practice guidelines state that enteral feedings should be initiated as soon as practical. The authors sought to evaluate compliance with early enteral nutrition (EN) guidelines, associated complications, and hospitalization outcomes in a prospective multicenter observational study. They conducted a retrospective review of mechanically ventilated burn patients enrolled in the prospective observational multicenter study “Inflammation and the Host Response to Injury.” Timing of initiation of tube feedings was recorded, with early EN defined as being started within 24 hours of admission. Univariate and multivariate analyses were performed to distinguish barriers to initiation of EN and the impact of early feeding on development of multiple organ dysfunction syndrome, infectious complications, days on mechanical ventilation, intensive care unit (ICU) length of stay, and survival. A total of 153 patients met study inclusion criteria. The cohort comprised 73% men, with a mean age of 41 ± 15 years and a mean %TBSA burn of 46 ± 18%. One hundred twenty-three patients (80%) began EN in the first 24 hours and 145 (95%) by 48 hours. Age, sex, inhalation injury, and full-thickness burn size were similar between those fed by 24 hours vs after 24 hours, except for higher mean Acute Physiology and Chronic Health Evaluation II scores (26 vs 23, P = .03) and smaller total burn size (44 vs 54% TBSA burn, P = .01) in those fed early. There was no significant difference in rates of hyperglycemia, abdominal compartment syndrome, or gastrointestinal bleeding between groups. Patients fed early had shorter ICU length of stay (adjusted hazard ratio 0.57, P = 0.03, 95% confidence interval 0.35–0.94) and reduced wound infection risk (adjusted odds ratio 0.28, P = 0.01, 95% confidence interval 0.10–0.76).

Comparative embryology expands our understanding of unique limb structures, such as that found in bats. Bat forelimb digits 2 to 5 are differentially elongated and joined by webbing, while the hindlimb digits are of similar length in many species. We compare limb development between the mouse and the Natal long-fingered bat, Miniopterus natalensis, to pinpoint the stage at which their limbs begin to differ. The bat forelimb differs from the mouse at Carollia stage (CS) 14 with the appearance of the wing membrane primordia. This difference is enhanced at CS 15 with the posterior expansion of the hand plate. The bat hindlimb begins to differ from the mouse between CS 15 and 16 when the foot plate undergoes a proximal expansion resulting in digit primordia of very similar length. Our findings support recent gene expression studies, which reveal a role for early patterning in the development of the bat limb. Copyright 2009 Wiley-Liss, Inc.

Surgical site infection is one of the most common complications for patients after sacrectomy, which often accompanied by poor wound healing, sinus formation and serious metabolic disturbance. We tried to avoid the surgical site infection caused by feces during early period after surgery through early fasting and total parenteral nutrition (TPN) support, then compared the clinical results of these patients with other patients that received enteral nutrition (EN) early after sacrectomy. Forty-eight patients after sacrectomy (the level of sacrectomy above S 2 ) were randomly divided into two groups: TPN group and EN group. The patients of two groups received different nutrition support from the first day to the seventh day after surgery, then the factors such as nutritional and metabolic status after surgery, incidence of complications as well as the time of incision healing and hospitalization were observed. The p-value of total serum protein, albumin, serum alanine aminotransferase, total bilirubin at seventh day after sacrectomy between TPN group and EN group is <0.0005. The p-value of hemoglobin at seventh day after sacrectomy between TPN group and EN group is 0.001. The p-value of total serum protein at fourteenth day after sacrectomy between TPN group and EN group is 0.003. The p-value of albumin and total bilirubin at fourteenth day after sacrectomy between TPN group and EN group is 0.001. The p-value of hemoglobin, serum alanine aminotransferase at fourteenth day after sacrectomy between TPN group and EN group is <0.0005. The incidence of gastrointestinal complication and delay of apparition of feces in EN group were lower than that in TPN group (p=0.041, p<0.0005). The incidence of surgical site infection, the time of incision healing and hospitalization in TPN group were lower than that in EN group (p=0.048, p=0.008, p<0.0005). The method of fasting and supported by TPN during the early period after sacrectomy contribute to the incision healing, meanwhile

The temporomandibular joint (TMJ) is a specialized synovial joint that is essential for the movement and function of the mammalian jaw. The TMJ develops from two mesenchymal condensations, and is composed of the glenoid fossa that originates from the otic capsule by intramembranous ossification, the mandibular condyle of the temporal bone and a fibrocartilagenous articular disc derived from a secondary cartilaginous joint by endochondral ossification. However, the development of the TMJ remains unclear. In the present study, the formation and development of the mouse TMJ was investigated between embryonic day 13.5 and post-natal day 180 in order to elucidate the morphological and molecular alterations that occur during this period. TMJ formation appeared to proceed in three stages: Initiation or blastema stage; growth and cavitation stage; and the maturation or completion stage. In order to investigate the activity of certain transcription factors on TMJ formation and development, the expression of extracellular matrix (ECM), sex determining region Y-box 9, runt-related transcription factor 2, Indian hedgehog homolog, Osterix, collagen I, collagen II, aggrecan, total matrix metalloproteinase (MMP), MMP-9 and MMP-13 were detected in the TMJ using in situ and/or immunohistochemistry. The results indicate that the transcription factors, ECM and MMP serve critical functions in the formation and development of the mouse TMJ. In summary, the development of the mouse TMJ was investigated, and the molecular regulation of mouse TMJ formation was partially characterized. The results of the present study may aid the systematic understanding of the physiological processes underlying TMJ formation and development in mice. PMID:26893634

Food insecurity and poor nutrition are key barriers to anti-retroviral therapy (ART) adherence. Culturally-appropriate and sustainable interventions that provide nutrition counseling for people on ART and of diverse nutritional statuses are needed, particularly given rising rates of overweight and obesity among people living with HIV (PLHIV). As part of scale-up of a nutritional counseling intervention, we recruited and trained 17 peer counselors from 14 government-run HIV clinics in Honduras to deliver nutritional counseling to ART patients using a highly interactive curriculum that was developed after extensive formative research on locally available foods and dietary patterns among PLHIV. All participants received the intervention; at baseline and 2 month follow-up, assessments included: 1) interviewer-administered, in-person surveys to collect data on household food insecurity (15-item scale), nutritional knowledge (13-item scale), dietary intake and diversity (number of meals and type and number of food groups consumed in past 24 hours); and 2) anthropometric measures (body mass index or BMI, mid-upper arm and waist circumferences). We used multivariable linear regression analysis to examine changes pre-post in food insecurity and the various nutritional outcomes while controlling for baseline characteristics and clinic-level clustering. Of 482 participants at baseline, we had complete follow-up data on 356 (74%), of which 62% were women, median age was 39, 34% reported having paid work, 52% had completed primary school, and 34% were overweight or obese. In multivariate analyses adjusting for gender, age, household size, work status, and education, we found that between baseline and follow-up, household food insecurity decreased significantly among all participants (β=-0.47, p<.05) and among those with children under 18 (β=-1.16, p<.01), while nutritional knowledge and dietary intake and diversity also significantly improved, (β=0.88, p<.001; β=0.30, p

Information on drivers of dispersal is critical for wildlife conservation but is rare for long-lived marine mammal species with large geographic ranges. We fit multi-state mark-recapture models to resighting data of 369 known-aged Steller sea lion (Eumetopias jubatus) females marked as pups on their natal rookeries in southeastern Alaska from 1994-2005 and monitored from 2001-15. We estimated probabilities of females being first observed parous at their natal site (natal philopatry), and of not moving breeding sites among years (breeding philopatry) at large (> 400 km, all five rookeries in southeastern Alaska) and small (< 4 km, all islands within the largest rookery, Forrester Island Complex, F) spatial scales. At the rookery scale, natal philopatry was moderately high (0.776-0.859) for most rookeries and breeding philopatry was nearly 1, with < 3% of females switching breeding rookeries between years. At more populous islands at F, natal philopatry was 0.500-0.684 versus 0.295-0.437 at less populous islands, and breeding philopatry was 0.919-0.926 versus 0.604-0.858. At both spatial scales, the probability of pupping at a non-natal site increased with population size of, and declined with distance from, the destination site. Natal philopatry of < 1 would increase gene flow, improve population resilience, and promote population recovery after decline in a heterogeneous environment. Very high breeding philopatry suggests that familiarity with neighboring females and knowledge of the breeding site (the topography of pupping sites and nearby foraging locations) may be a critical component to reproductive strategies of sea lions.

The prevalence of marijuana use during pregnancy ranges from 3- 30% , and most of this is for recreational purposes. Marijuana exposure during pregnancy has been linked with low birth weight babies and other adverse child health outcomes. Twitter is a popular news and social networking outlet, and is frequently used to access information about population health and behavior. The primary objective of this study was to investigate the types of messages disseminated on Twitter about marijuana use and infant and maternal health. The secondary objective was to describe the reported health outcomes associated with prenatal and postnatal marijuana use. Tweets were collected from the inception of Twitter (2006) until April 2017. If tweets included links, these links were examined to investigate the source of the message and to clarify the user's intent. In total, 550 tweets were captured, with most tweets (77.6%) having a neutral tweet tone, suggesting uncertainty about the health effects associated with pre- and post-natal marijuana exposure. The sources attached to the original tweets, however, were more likely to report on negative health outcomes. The most common health outcomes associated with prenatal marijuana exposure were: poor brain development (27.3%), inadequate development of the nervous system (23.6%), low birth weight (23.3%), poor behavioral outcomes (21.0%), and infant memory issues (19.3%). The inverse association between marijuana use and the quality and quantity of milk produced by the mother was the most commonly reported tweet for the lactation period.

Impact of body size, nutrition and socioeconomic position in early life on the epigenome: a systematic review protocol.

2017-07-05

Body size, nutrition and socioeconomic position (SEP) in early life have been associated with a range of later life health outcomes. Epigenetic regulation is one mechanism through which these early life factors may impact later life health. The aim of this review protocol is to outline procedures to document the influence of body size, nutrition and SEP in early life on the epigenome. MEDLINE, Embase and BIOSIS will be systematically searched using pre-defined keywords. Additional studies will be identified through manual searching of reference lists. Two independent researchers will assess the eligibility and quality of each study, with disagreements being resolved through discussion or a third reviewer. Studies will be included if they have epigenetic markers measured either at the same time as, or after, the early life exposure and, have a measure of body size, nutrition or SEP in early life (up to 12 years), are in the English language and are from a sample of community-dwelling participants. This protocol will be used to collate the evidence for the effect of early life factors on the epigenome. Findings will form a component of a wider research study examining epigenetic responses to exposures in early life and over the life course and its impact on healthy ageing using data from population-based cohort studies.

Sub-Saharan Africa is the last region to undergo a nutrition transition and can still avoid its adverse health outcomes. The article explores emerging responses to "bend the curve" in sub-Saharan Africa's nutrition transition to steer public health outcomes onto a healthier trajectory. Early responses in 3 countries at different stages of food system transformation are examined: South Africa-advanced, Ghana-intermediate, and Uganda-early. By comparing these with international experience, actions are proposed to influence nutrition and public health trajectories as Africa's food systems undergo rapid structural change. Arising from rapid urbanization and diet change, major public health problems associated with overweight are taking place, particularly in South Africa and among adult women. However, public health responses are generally tepid in sub-Saharan Africa. Only in South Africa have policy makers instituted extensive actions to combat overweight and associated noncommunicable diseases through regulation, education, and public health programs. Elsewhere, in countries in the early and middle stages of transition, public health systems continue to focus their limited resources primarily on undernutrition. Related pressures on the supply side of Africa's food systems are emerging that also need to be addressed. Three types of intervention appear most feasible: maternal and child health programs to simultaneously address short-term undernutrition problems while at the same time helping to reduce future tendencies toward overweigh; regulatory and fiscal actions to limit access to unhealthy foods; and modernization of Africa's agrifood food system through job skills training, marketing reforms, and food industry entrepreneurship. © The Author(s) 2016.

Epigenetic modifications are among the most important mechanisms by which environmental factors can influence early cellular differentiation and create new phenotypic traits during pregnancy and within the neonatal period without altering the deoxyribonucleic acid sequence. A number of antenatal and postnatal factors, such as maternal and neonatal nutrition, pollutant exposure, and the composition of microbiota, contribute to the establishment of epigenetic changes that can not only modulate the individual adaptation to the environment but also have an influence on lifelong health and disease by modifying inflammatory molecular pathways and the immune response. Postnatal intestinal colonization, in turn determined by maternal flora, mode of delivery, early skin-to-skin contact and neonatal diet, leads to specific epigenetic signatures that can affect the barrier properties of gut mucosa and their protective role against later insults, thus potentially predisposing to the development of late-onset inflammatory diseases. The aim of this review is to outline the epigenetic mechanisms of programming and development acting within early-life stages and to examine in detail the role of maternal and neonatal nutrition, microbiota composition, and other environmental factors in determining epigenetic changes and their short- and long-term effects.

Effects of resource variation during early life and adult social environment on contest outcomes in burying beetles: a context-dependent silver spoon strategy?

PubMed

Hopwood, Paul E; Moore, Allen J; Royle, Nick J

2014-06-22

Good early nutritional conditions may confer a lasting fitness advantage over individuals suffering poor early conditions (a 'silver spoon' effect). Alternatively, if early conditions predict the likely adult environment, adaptive plastic responses might maximize individual performance when developmental and adult conditions match (environmental-matching effect). Here, we test for silver spoon and environmental-matching effects by manipulating the early nutritional environment of Nicrophorus vespilloides burying beetles. We manipulated nutrition during two specific early developmental windows: the larval environment and the post-eclosion environment. We then tested contest success in relation to variation in adult social environmental quality experienced (defined according to whether contest opponents were smaller (good environment) or larger (poor environment) than the focal individual). Variation in the larval environment influenced adult body size but not contest success per se for a given adult social environment experienced (an 'indirect' silver spoon effect). Variation in post-eclosion environment affected contest success dependent on the quality of the adult environment experienced (a context-dependent 'direct' silver spoon effect). By contrast, there was no evidence for environmental-matching. The results demonstrate the importance of social environmental context in determining how variation in nutrition in early life affects success as an adult.

The incidence of early post-traumatic seizures after civilian traumatic brain injury ranges 4-25%. The control of early post-traumatic seizure is mandatory because these acute insults may add secondary damage to the already damaged brain with poor outcome. Prophylactic use of anti-epileptic drugs have been found to be have variable efficacy against early post-traumatic seizures. The objective of this study was to compare the efficacy of Phenytion and Levetiracetam in prevention of early post-traumatic seizures in moderate to severe traumatic brain injury. This randomized controlled trial was conducted in department of Neurosurgery, Ayub Medical College, Abbottabad from March, 2012 to March 2013. The patients with moderate to severe head injury were randomly allocated in two groups. Patients in group A were given phenytoin and patients in group B were given Levetiracetam. Patients were followed for one week to detect efficacy of drug in terms of early post traumatic seizures. The 154 patients included in the study were equally divided into two groups. Out of 154 patients 115 (74.7%) were male while 29 (25.3%) were females. Age of patients ranges from 7-48 (24.15±9.56) years. Ninety one (59.1%) patients had moderate head injury while 63 (40.9%) patients had severe head injury. Phenytoin was effective in preventing early post traumatic seizures in 73 (94.8%) patients whereas Levetiracetam effectively controlled seizures in 70 (90.95%) cases (p-value of .348). There is no statistically significant difference in the efficacy of Phenytoin and Levetiracetam in prophylaxis of early posttraumatic seizures in cases of moderate to severe traumatic brain injury.

Background Aprotinin was a commonly utilized pharmacological agent for homeostasis in cardiac surgery but was discontinued resulting in the extensive use of lysine analogues. This study tested the hypothesis that early post-operative adverse events and blood product utilization would affected in this post-aprotinin era. Methods/Results Adult patients (n=781) undergoing coronary artery bypass (CABG), valve replacement, or both from November 1, 2005-October 31, 2008 at a single institution were included. Multiple logistic regression modeling and propensity scoring were performed on 29 pre-operative and intra-operative variables in patients receiving aprotinin (n=325) or lysine analogues (n=456). The propensity adjusted relative risk (RR;95% confidence interval;CI) for the intra-operative use of packed red blood cells (RR:0.75;CI:0.57–0.99), fresh frozen plasma (RR:0.37;0.21–0.64), and cryoprecipitate (RR:0.06;CI:0.02–0.22) were lower in the aprotinin versus lysine analogue group (all p<0.05). The risk for mortality (RR:0.53;CI:0.16–1.79) and neurological events (RR:0.87;CI:0.35–2.18) remained similar between groups, whereas a trend for reduced risk for renal dysfunction was observed in the aprotinin group. Conclusions In the post-aprotinin era with the exclusive use of lysine analogues, the relative risk of early post-operative outcomes such as mortality and renal dysfunction have not improved, but the risk for the intra-operative use of blood products has increased. Thus, improvements in early post-operative outcomes have not been realized with the discontinued use of aprotinin, but rather increased blood product utilization has occurred with the attendant costs and risks inherent with this strategy.

Although effective health and nutrition interventions for reducing child mortality and morbidity exist, direct evidence of effects on cognitive, motor, and psychosocial development is lacking. To review existing evidence for health and nutrition interventions affecting direct measures of (and pathways to) early child development. Reviews and recent overviews of interventions across the continuum of care and component studies. We selected systematic reviews detailing the effectiveness of health or nutrition interventions that have plausible links to child development and/or contain direct measures of cognitive, motor, and psychosocial development. A team of reviewers independently extracted data and assessed their quality. Sixty systematic reviews contained the outcomes of interest. Various interventions reduced morbidity and improved child growth, but few had direct measures of child development. Of particular benefit were food and micronutrient supplementation for mothers to reduce the risk of small for gestational age and iodine deficiency, strategies to reduce iron deficiency anemia in infancy, and early neonatal care (appropriate resuscitation, delayed cord clamping, and Kangaroo Mother Care). Neuroprotective interventions for imminent preterm birth showed the largest effect sizes (antenatal corticosteroids for developmental delay: risk ratio 0.49, 95% confidence interval 0.24 to 1.00; magnesium sulfate for gross motor dysfunction: risk ratio 0.61, 95% confidence interval 0.44 to 0.85). Given the focus on high-quality studies captured in leading systematic reviews, only effects reported within studies included in systematic reviews were captured. These findings should guide the prioritization and scale-up of interventions within critical periods of early infancy and childhood, and encourage research into their implementation at scale.

To investigate the effects of early enteral nutrition (EEN) on intra-abdominal pressure (IAP) and disease severity in patients with severe acute pancreatitis (SAP). Enteral nutrition (EN) was started within 48 h after admission in the EEN group and from the 8th day in the delayed enteral nutrition (DEN) group. The IAP and intra-abdominal hypertension (IAH) incidence were recorded for 2 weeks. The caloric intake and feeding intolerance (FI) incidence were recorded daily after EN was started. The severity markers and clinical outcome variables were also recorded. Sixty patients were enrolled to this study. No difference about IAP was found. The IAH incidence of the EEN group was significantly lower than that of the DEN group from the 9th day (8/30 versus 18/30; P = 0.009) after admission. The FI incidence of the EEN group was higher than that of the DEN group during the initial 3 days of feeding (25/30 versus 12/30; P = 0.001; 22/30 versus 9/30; P = 0.001; 15/30 versus 4/30; P = 0.002). Patients with an IAP <15 mmHg had lower FI incidence than those with an IAP ≥15 mmHg on the 1st day (20/22 versus 17/38; P < 0.001), the 3rd day (11/13 versus 8/47; P < 0.001), and the 7th day (3/5 versus 3/55; P = 0.005) of feeding. The severity markers and clinical outcome variables of the EEN group were significantly improved. Early enteral nutrition did not increase IAP. In contrast, it might prevent the development of IAH. In addition, EEN might be not appropriate during the initial 3-4 days of SAP onset. Moreover, EN might be of benefit to patients with an IAP <15 mmHg. Early enteral nutrition could improve disease severity and clinical outcome, but did not decrease mortality of SAP.

Perinatal depression is a debilitating disorder experienced during pregnancy and/or the first year post-partum. Recently, maternal dietary intake during pregnancy has emerged as a possible area of intervention for the prevention of mental disorders in women and their offspring. However, the relationship between antenatal diet quality and perinatal depressive symptoms remains poorly understood. The current study explored the predictive role of antenatal diet quality for antenatal and post-natal depressive symptoms. Pregnant women (n = 167) were recruited between February 2010 and December 2011. Women completed the Edinburgh Postnatal Depression Scale at time 1 [T1, mean weeks gestation = 16.70, standard deviation (SD) = 0.91], time 2 (T2, mean weeks gestation = 32.89, SD = 0.89) and time 3 (T3, mean weeks post-partum = 13.51, SD = 1.97) and a food frequency questionnaire at T1 and T2. Diet quality was determined by extracting dietary patterns via principal components analysis. Two dietary patterns were identified: 'healthy' (including fruit, vegetables, fish and whole grains) and 'unhealthy' (including sweets, refined grains, high-energy drinks and fast foods). Associations between dietary patterns and depressive symptoms were investigated by path analyses. While both 'healthy' and 'unhealthy' path models showed good fit, only one significant association consistent with study hypotheses was found, an 'unhealthy' diet was associated with increased depressive symptoms at 32 weeks gestation. Given that this association was cross-sectional, it was not possible to make any firm conclusions about the predictive nature of either dietary patterns or depressive symptoms. Dietary intervention studies or larger prospective studies are therefore recommended. © 2015 John Wiley & Sons Ltd.

The Pró-Natal project is a collaborative initiative that aims to improve maternal and infant health in a deprived community in Natal, Northeast Brazil. To assess the perinatal and infant mortality in this population of 40,000, we have collected over a 2-year period a consecutive series of 39 autopsy examinations on deaths under 1 year of age. During this period there were 2212 live births in the study population. The 14 perinatal deaths are described using the Wrigglesworth classification, and the 25 infant deaths, using a clinicopathological system. The contribution of normally formed stillbirths was small (14%), which probably reflects the underreporting of stillbirths in this community. The most common cause of death in the live births was complications of prematurity (43%). Specific causes (22%) of perinatal deaths were predominantly infections, including one case of congenital syphilis. Perinatal asphyxia was diagnosed in 14%, and there was one case (7%) of a chromosome abnormality. Infant deaths were predominantly due to respiratory (45%) and gastrointestinal infections (28%), with chronic malnutrition as an underlying cause in 80% of cases. Prenatal care could theoretically have prevented three of the perinatal deaths, and a further six deaths could have been avoided by improved management of labor and the immediate neonatal period. Prevention of malnutrition and improved treatment of acute infections would contribute to a reduction in infant mortality in this population. The Pró-Natal project will use these data to design preventative interventions to reduce perinatal and infant mortality in this community.

Experiencing El Niño conditions during early life reduces recruiting probabilities but not adult survival.

In wild long-lived animals, analysis of impacts of stressful natal conditions on adult performance has rarely embraced the entire age span, and the possibility that costs are expressed late in life has seldom been examined. Using 26 years of data from 8541 fledglings and 1310 adults of the blue-footed booby ( Sula nebouxii ), a marine bird that can live up to 23 years, we tested whether experiencing the warm waters and food scarcity associated with El Niño in the natal year reduces recruitment or survival over the adult lifetime. Warm water in the natal year reduced the probability of recruiting; each additional degree (°C) of water temperature meant a reduction of roughly 50% in fledglings' probability of returning to the natal colony as breeders. Warm water in the current year impacted adult survival, with greater effect at the oldest ages than during early adulthood. However, warm water in the natal year did not affect survival at any age over the adult lifespan. A previous study showed that early recruitment and widely spaced breeding allow boobies that experience warm waters in the natal year to achieve normal fledgling production over the first 10 years; our results now show that this reproductive effort incurs no survival penalty, not even late in life. This pattern is additional evidence of buffering against stressful natal conditions via life-history adjustments.

Weight loss is frequently observed in patients with Alzheimer's disease (AD); however, the underlying mechanisms are not well understood. To clarify the associations between nutritional status and AD-related brain changes using Pittsburgh Compound-B (PiB)-PET, fluorodeoxyglucose (FDG)-PET, and structural MRI. The subjects were 34 amyloid-β (Aβ)-positive individuals with mild cognitive impairment or early AD (prodromal/early AD), and 55 Aβ-negative cognitively normal (CN) subjects who attended the Multimodal Neuroimaging for AD Diagnosis (MULNIAD) study. Nutritional status of the subjects was assessed by body mass index and waist to height ratio (waist circumference/height). The associations between nutritional status and brain changes were examined by multiple regression analysis using statistical parametric mapping. In the prodromal/early AD group, nutritional status was significantly positively correlated with regional cerebral glucose metabolism (rCGM) in the medial prefrontal cortices, while different topographical associations were seen in the CN group, suggesting these changes were AD-specific. Aβ deposition and gray matter volume were not significantly associated with nutritional status. Sub-analysis in the prodromal/early AD group demonstrated that fat mass index, but not fat-free mass index, was positively correlated with rCGM in the medial prefrontal areas. This present study provides preliminary results suggesting that hypometabolism in the medial prefrontal areas is specifically associated with AD-related weight loss, and decrease in fat mass may have a key role.

Nutrition in early life and the programming of adult disease: the first 1000 days

PubMed

Moreno Villares, José Manuel

2016-07-12

Development during fetal life and infancy is characterized by rapid growth as well as the maturation of organs and systems. Changes, both in quality and quality, in nutrients during these periods may permanently infl uence the way these organs mature and function. These effects are termed as “programming” and play an important role in the presence of non-transmissible diseases through the lifespan. Specially cardiovascular disease, metabolic disorders and carbohydrate intolerance. Nutritional deficits during pregnancy, leading to intrauterine growth restriction, are associated to a higher risk of type 2 diabetes, and coronary disease among the offspring. This infl uence does not stop with the delivery but early nutrition in infancy, type of lactation, and the way and time solid foods are introduced, does play a role in this programming. Nutritional and non-nutritional factors alter the expression of some genes, resulting in effective remodeling of tissue structure and functionality. These epigenetic modifications can be transmitted to further generations, adding evidence that hereditable epigenetic modifications play a critical role in nutritional programming. But, at the same time, it opens a window of opportunity to decrease the burden of non-transmissible disease by a clever advise on nutrition during pregnancy and across the first 2 years of life (the so-called 1000 days strategy).

Early life nutrition, epigenetics and programming of later life disease.

The global pandemic of obesity and type 2 diabetes is often causally linked to marked changes in diet and lifestyle; namely marked increases in dietary intakes of high energy diets and concomitant reductions in physical activity levels. However, less attention has been paid to the role of developmental plasticity and alterations in phenotypic outcomes resulting from altered environmental conditions during the early life period. Human and experimental animal studies have highlighted the link between alterations in the early life environment and increased risk of obesity and metabolic disorders in later life. This link is conceptualised as the developmental programming hypothesis whereby environmental influences during critical periods of developmental plasticity can elicit lifelong effects on the health and well-being of the offspring. In particular, the nutritional environment in which the fetus or infant develops influences the risk of metabolic disorders in offspring. The late onset of such diseases in response to earlier transient experiences has led to the suggestion that developmental programming may have an epigenetic component, as epigenetic marks such as DNA methylation or histone tail modifications could provide a persistent memory of earlier nutritional states. Moreover, evidence exists, at least from animal models, that such epigenetic programming should be viewed as a transgenerational phenomenon. However, the mechanisms by which early environmental insults can have long-term effects on offspring are relatively unclear. Thus far, these mechanisms include permanent structural changes to the organ caused by suboptimal levels of an important factor during a critical developmental period, changes in gene expression caused by epigenetic modifications (including DNA methylation, histone modification, and microRNA) and permanent changes in cellular ageing. A better understanding of the epigenetic basis of developmental programming and how these effects may be

Tailoring nutrition therapy to illness and recovery.

Without doubt, in medicine as in life, one size does not fit all. We do not administer the same drug or dose to every patient at all times, so why then would we live under the illusion that we should give the same nutrition at all times in the continuum of critical illness? We have long lived under the assumption that critical illness and trauma lead to a consistent early increase in metabolic/caloric need, the so-called "hypermetabolism" of critical illness. What if this is incorrect? Recent data indicate that early underfeeding of calories (trophic feeding) may have benefits and may require consideration in well-nourished patients. However, we must confront the reality that currently ICU nutrition delivery worldwide is actually leading to "starvation" of our patients and is likely a major contributor to poor long-term quality of life outcomes. To begin to ascertain the actual calorie and protein delivery required for optimal ICU recovery, an understanding of "starvation" and recovery from starvation and lean body mass (LBM) loss is needed. To begin to answer this question, we must look to the landmark Minnesota Starvation Study from 1945. This trial defines much of the world's knowledge about starvation, and most importantly what is required for recovery from starvation and massive LBM loss as occurs in the ICU. Recent and historic data indicate that critical illness is characterized by early massive catabolism, LBM loss, and escalating hypermetabolism that can persist for months or years. Early enteral nutrition during the acute phase should attempt to correct micronutrient/vitamin deficiencies, deliver adequate protein, and moderate nonprotein calories in well-nourished patients, as in the acute phase they are capable of generating significant endogenous energy. Post resuscitation, increasing protein (1.5-2.0 g/kg/day) and calories are needed to attenuate LBM loss and promote recovery. Malnutrition screening is essential and parenteral nutrition can be safely

If competitive ability depends on body size, then the optimal natal movement from areas of high local population density can also be predicted to be size-dependent. Specifically, small, competitively-inferior individuals would be expected to benefit most from moving to areas of lower local density. Here we evaluate whether individual variation in natal movement...

The efficacy of enteral nutrition in postoperative nutritional management is known, but the effects on gastrointestinal motility and nutrition have not yet been elucidated. The purpose of this study was to compare the effects of enteral and parenteral nutrition soon after open abdominal surgery on gastrointestinal motility and nutritional status. A partial resection of rectum models was prepared to compare two types of nutrient administration: enteral nutrition and total parenteral nutrition. The differences between the effects of nutrition types in terms of gastrointestinal motility and nutritional status were investigated. Enteral nutrition contributed to recovery of gastrointestinal motility and maintenance of nutritional status. Enteral nutrition should therefore be initiated soon after surgery if the gastrointestinal tract is available.

To determine whether the timing and route of nutritional support strategy affect length of hospitalization in dogs with naturally occurring septic peritonitis. Retrospective study encompassing cases from 2000 to 2009. University teaching hospital. Forty-five dogs that survived septic peritonitis. None. Nutritional strategy for each dog was categorized as either enteral nutrition (EN: free choice voluntary eating or assisted tube feeding) or central parenteral nutrition (CPN). Early nutritional support was defined as consistent caloric intake initiated within 24 hours postoperatively. Consistent caloric intake occurring after 24 hours was defined as delayed nutritional support. Data reflective of nutritional status included body condition score, serum albumin concentration, and duration of inappetence before and during hospitalization. Body weight change from the beginning to the end of hospitalization was calculated. A modified Survival Prediction Index 2 score was calculated for each dog at admission. Additional clinical data recorded for comparison of illness severity included indicators of severe inflammation (eg, presence of toxic changes in neutrophils and immature neutrophils), coagulopathy (eg, prolonged prothrombin time and activated partial thromboplastin time), the use of vasopressors and blood transfusions, and presence of concurrent illnesses. Nutrition-related complications were classified as mechanical, metabolic, or septic complications. Multivariate linear regression analyses were used to determine the relationship of nutritional strategy with hospitalization length, while considering the presence of nutrition-related complications, the nutritional status- and illness severity-related variables. While controlling for other variables, dogs that received early nutrition had significantly shorter hospitalization length (by 1.6 days). No statistically significant association was found between route of nutrition and hospitalization length. The presence

Performance of UNHCR nutrition programs in post-emergency refugee camps

PubMed Central

2011-01-01

Background The United Nations High Commissioner for Refugees (UNHCR) launched a health information system (HIS) in 2005 to enhance quality and consistency of routine health information available in post-emergency refugee camps. This paper reviews nutrition indicators and examines their application for monitoring and evaluating the performance of UNHCR nutrition programs in more than 90 refugee camps in 18 countries. Methods The HIS is a primary source of feeding program data which is collected using standardized case definitions and reporting formats across refugee camps in multiple settings. Data was aggregated across time periods and within and across countries for analysis. Basic descriptive statistics were then compared to UNHCR program performance standards. Results Camp populations covered by the HIS ranged from 192,000 to 219,000 between 2007 and mid-2009; 87% of under five children covered by the HIS were in Africa and 13% in Asia. Average moderate acute malnutrition (MAM) and severe acute malnutrition (SAM) rates reported in 74 of 81 camps for the 2007-2009 time periods were 7.0% and 1.6%, respectively. The supplementary feeding program (SFP) admission rate was 151/1000/yr with 93% of SFP admissions occurring in Africa. SFP performance consistently exceeded all UNHCR standards with the exception of length of enrollment. Average length of SFP enrollment was 12 weeks in Africa and 22 weeks in Asia as compared to the UNHCR standard of < 8 weeks. The therapeutic feeding program (TFP) admission was 22/1000/yr with 95% of TFP admissions in Africa. TFP performance met UNHCR standards with the exception of daily weight gain. Conclusions Inclusion of children identified as moderately and severely wasted in the HIS would allow UNHCR to better track and respond to changes in nutrition status. Improved growth monitoring coverage or active malnutrition surveillance would increase UNHCR's ability to identify and treat cases of acute malnutrition. Expansion of nutrition

To investigate the effects of early enteral immunonutrition on postoperative immune function and rehabilitation of gastric cancer patients with nutritional risk. New hospitalized patients with gastric cancer were evaluated the nutrient status based on NRS 2002. The patients who scored between 3 to 5 points were randomized into two groups(30 cases for each group), and those in experimental group were given 7-d early postoperative enteral immune nutrition, those in control group were given normal nutrition. The immune indexes (CD3 + , CD4 + , CD8 + and CD4 + /CD8 + ) and nutritional indexes(transferrin, pre-albumin, albumin) were measured before operation and at the 3 rd and 7 th day postoperatively. In addition, the first flatus time, gastrointestinal adverse reactions and complications, length of hospital stays were compared between the two groups. The level of CD4 + /CD8 + and transferrin, pre-albumin, albumin in experimental group were significantly higher than those in control group at the third and seventh day postoperatively ( P <0.05).Compared with the control group, the experimental group had shorter first flatus time after surgery, which were (63.5±7.3) h vs. (72.8±8.6 ) h respectively ( P <0.05).There were no statistically difference on pneumonia, anastomosis leakage, severe abdominal distension, inflammatory bowel obstruction and total postoperative hospitalization time between the two groups ( P >0.05). Early enteral immunonutrition can effectively promote the recovery of nutritional status and immune function in gastric cancer patients with nutrition risk.

Perinatal nutrition interventions and post-partum depressive symptoms.

Postpartum depression (PPD) is the most prevalent mood disorder associated with childbirth. No single cause of PPD has been identified, however the increased risk of nutritional deficiencies incurred through the high nutritional requirements of pregnancy may play a role in the pathology of depressive symptoms. Three nutritional interventions have drawn particular interest as possible non-invasive and cost-effective prevention and/or treatment strategies for PPD; omega-3 (n-3) long chain polyunsaturated fatty acids (LCPUFA), vitamin D and overall diet. We searched for meta-analyses of randomised controlled trials (RCT's) of nutritional interventions during the perinatal period with PPD as an outcome, and checked for any trials published subsequently to the meta-analyses. Fish oil: Eleven RCT's of prenatal fish oil supplementation RCT's show null and positive effects on PPD symptoms. Vitamin D: no relevant RCT's were identified, however seven observational studies of maternal vitamin D levels with PPD outcomes showed inconsistent associations. Diet: Two Australian RCT's with dietary advice interventions in pregnancy had a positive and null result on PPD. With the exception of fish oil, few RCT's with nutritional interventions during pregnancy assess PPD. Further research is needed to determine whether nutritional intervention strategies during pregnancy can protect against symptoms of PPD. Given the prevalence of PPD and ease of administering PPD measures, we recommend future prenatal nutritional RCT's include PPD as an outcome. Copyright © 2016 Elsevier B.V. All rights reserved.

Early Life Nutrition and Energy Balance Disorders in Offspring in Later Life

2015-01-01

The global pandemic of obesity and type 2 diabetes is often causally linked to changes in diet and lifestyle; namely increased intake of calorically dense foods and concomitant reductions in physical activity. Epidemiological studies in humans and controlled animal intervention studies have now shown that nutritional programming in early periods of life is a phenomenon that affects metabolic and physiological functions throughout life. This link is conceptualised as the developmental programming hypothesis whereby environmental influences during critical periods of developmental plasticity can elicit lifelong effects on the health and well-being of the offspring. The mechanisms by which early environmental insults can have long-term effects on offspring remain poorly defined. However there is evidence from intervention studies which indicate altered wiring of the hypothalamic circuits that regulate energy balance and epigenetic effects including altered DNA methylation of key adipokines including leptin. Studies that elucidate the mechanisms behind these associations will have a positive impact on the health of future populations and adopting a life course perspective will allow identification of phenotype and markers of risk earlier, with the possibility of nutritional and other lifestyle interventions that have obvious implications for prevention of non-communicable diseases.

The interplay of early-life stress, nutrition, and immune activation programs adult hippocampal structure and function

Hoeijmakers, Lianne; Lucassen, Paul J.; Korosi, Aniko

2015-01-01

Early-life adversity increases the vulnerability to develop psychopathologies and cognitive decline later in life. This association is supported by clinical and preclinical studies. Remarkably, experiences of stress during this sensitive period, in the form of abuse or neglect but also early malnutrition or an early immune challenge elicit very similar long-term effects on brain structure and function. During early-life, both exogenous factors like nutrition and maternal care, as well as endogenous modulators, including stress hormones and mediator of immunological activity affect brain development. The interplay of these key elements and their underlying molecular mechanisms are not fully understood. We discuss here the hypothesis that exposure to early-life adversity (specifically stress, under/malnutrition and infection) leads to life-long alterations in hippocampal-related cognitive functions, at least partly via changes in hippocampal neurogenesis. We further discuss how these different key elements of the early-life environment interact and affect one another and suggest that it is a synergistic action of these elements that shapes cognition throughout life. Finally, we consider different intervention studies aiming to prevent these early-life adversity induced consequences. The emerging evidence for the intriguing interplay of stress, nutrition, and immune activity in the early-life programming calls for a more in depth understanding of the interaction of these elements and the underlying mechanisms. This knowledge will help to develop intervention strategies that will converge on a more complete set of changes induced by early-life adversity. PMID:25620909

hospital malnutrition is a frequent worldwide problem and its potential issues related include increased complications, length of stay, mortality, and healthcare costs. the aim of this study was to establish the cost-effectiveness of early nutritional therapy for malnourished patients in a high complexity hospital. this analytical study with economic assessment included 227 adult hospitalised and malnourished according to the Subjective Global Assessment. The cohort prospective received Early Nutrition Therapy (ENT), whereas the cohort retrospective received Delayed Nutrition Therapy (DNT). The measures of cost-effectiveness included costs by: length of stay, complications and discharge condition. the cohorts were similar in demographic and clinical characteristics, except that the median age, for the ENT was 61 years (interquartile range [IQR]: 48-71) and for the DNT was 55 years (IQR: 44-67) (p = 0.024). The median length of stay was lower in the ENT (11 days, IQR: 7-17) than in the DNT (18 days, IQR: 10-28) (p < 0.001). The cost per patient discharged alive was US $ 10,261.55 in the ENT and US $ 15,553.11 in the DNT (p=0.043); the cost per patient with complications was US $ 13,663.90 in the ENT and US $ 17,860.32 in the DNT (p= 0.058). ENT increased the likelihood of being discharged alive, RR adjusted=0.31; 95% confidence interval (CI): 0.1; 0.6; (p<0.001) and decreased the likelihood of complications RR crude=0.8; 95% CI: 0.6; 0.9; (p=0.006). early nutritional therapy for malnourished adult patients appears to be cost-effective because it can reduce the length of stay, complications, mortality and associated costs.

The Interagency Committee on Human Nutrition Research (ICHNR) is charged with improving the planning, coordination, and communication among federal agencies engaged in nutrition research and with facilitating the development and updating of plans for federal research programs to meet current and future domestic and international needs for nutrition. The ICHNR is co-chaired by the USDA Under Secretary for Research, Education, and Economics and Chief Scientist and the US Department of Health and Human Services Assistant Secretary for Health and is made up of >10 departments and agencies. Once the ICHNR was reassembled after a 10-y hiatus, the ICHNR recognized a need for a written roadmap to identify critical human nutrition research gaps and opportunities. This commentary provides an overview of the process the ICHNR undertook to develop a first-of-its-kind National Nutrition Research Roadmap, which was publicly released on 4 March 2016. The primary audience for the Roadmap is federal science agency leaders, along with relevant program and policy staff who rely on federally supported human nutrition research, in addition to the broader scientific community. The Roadmap is framed around the following 3 questions: 1 ) How can we better understand and define eating patterns to improve and sustain health? 2 ) What can be done to help people choose healthy eating patterns? 3 ) How can we develop and engage innovative methods and systems to accelerate discoveries in human nutrition? Within these 3 questions, 11 topical areas were identified on the basis of the following criteria: population impact, feasibility given current technological capacities, and emerging scientific opportunities. This commentary highlights initial federal and some professional research society efforts to address the Roadmap's research and resource priorities. We conclude by noting examples of early collaborations and partnerships to move human nutrition research forward in the 21st century. © 2017

Emergent categorical representation of natural, complex sounds resulting from the early post-natal sound environment

Cortical sensory representations can be reorganized by sensory exposure in an epoch of early development. The adaptive role of this type of plasticity for natural sounds in sensory development is, however, unclear. We have reared rats in a naturalistic, complex acoustic environment and examined their auditory representations. We found that cortical neurons became more selective to spectrotemporal features in the experienced sounds. At the neuronal population level, more neurons were involved in representing the whole set of complex sounds, but fewer neurons actually responded to each individual sound, but with greater magnitudes. A comparison of population-temporal responses to the experienced complex sounds revealed that cortical responses to different renderings of the same song motif were more similar, indicating that the cortical neurons became less sensitive to natural acoustic variations associated with stimulus context and sound renderings. By contrast, cortical responses to sounds of different motifs became more distinctive, suggesting that cortical neurons were tuned to the defining features of the experienced sounds. These effects lead to emergent “categorical” representations of the experienced sounds, which presumably facilitate their recognition. PMID:23747304

There are few longitudinal data on nutritional status and body composition of patients undergoing allogeneic hematopoietic cell transplantation (alloHCT). We assessed nutritional status of 105 patients before alloHCT and its course during the early post-transplant period to day +30 and day +100 via weight history, body mass index (BMI) normalized for gender and age, Subjective Global Assessment, phase angle normalized for gender, age, and BMI, and fat-free and body fat masses. Furthermore, we present a multivariate regression model investigating the impact of factors on body weight. At admission, 23.8% reported significant weight losses (>5%) in the previous 6 months, and we noted 31.5% with abnormal age- and sex-adjusted BMI values (10th, 90th percentiles). BMI decreased significantly (P<0.0001) in both periods by 11% in total, meaning a weight loss of 8.6±5.7 kg. Simultaneously, the patients experienced significant losses (P<0.0001) of both fat-free and body fat masses. Multivariate regression model revealed clinically relevant acute GVHD (parameter estimate 1.43; P=0.02) and moderate/severe anorexia (parameter estimate 1.07; P=0.058) as independent factors influencing early weight loss. In conclusion, our results show a significant deterioration in nutritional status during the early post-transplant period. Predominant alloHCT-associated complications such as anorexia and acute GVHD became evident as significant factors influencing nutritional status.

The development of the immune system begins during embryogenesis, continues throughout fetal life, and completes its maturation during infancy. Exposure to immune-toxic compounds at levels producing limited/transient effects in adults, results in long-lasting or permanent immune deficits when it occurs during perinatal life. Potentially harmful radiofrequency (RF) exposure has been investigated mainly in adult animals or with cells from adult subjects, with most of the studies showing no effects. Is the developing immune system more susceptible to the effects of RF exposure? To address this question, newborn mice were exposed to WiFi signals at constant specific absorption rates (SAR) of 0.08 or 4 W/kg, 2h/day, 5 days/week, for 5 consecutive weeks, starting the day after birth. The experiments were performed with a blind procedure using sham-exposed groups as controls. No differences in body weight and development among the groups were found in mice of both sexes. For the immunological analyses, results on female and male newborn mice exposed during early post-natal life did not show any effects on all the investigated parameters with one exception: a reduced IFN-γ production in spleen cells from microwaves (MW)-exposed (SAR 4 W/kg) male (not in female) mice compared with sham-exposed mice. Altogether our findings do not support the hypothesis that early post-natal life exposure to WiFi signals induces detrimental effects on the developing immune system. Copyright © 2011 Elsevier Ltd.

Female green turtles exhibit strong nest-site fidelity as adults, but whether the nesting beach is the natal site is not known. Under the natal homing hypothesis, females return to their natal beach to nest, whereas under the social facilitation model, virgin females follow experienced breeders to nesting beaches and after a "favorable" nesting experience, fix on that site for future nestings. Differences shown in mitochondrial DNA genotype frequency among green turtle colonies in the Caribbean Sea and Atlantic Ocean are consistent with natal homing expectations and indicate that social facilitation to nonnatal sites is rare.

Increasing reproductive performance of post-partum lactating dairy cows is a multi-factorial challenge involving disciplines of production medicine, nutrition, physiology and herd management. Systems of programmed timed insemination have been fine-tuned to achieve pregnancy per artificial inseminations (AI) approximating 45%. Systems have optimized follicle development, integrated follicle development with timing of induced corpus luteum regression and fine-tuned sequential timing of induced ovulation and AI. Use of programmes for insemination have identified occurrence of anovulatory ovarian status, body condition, uterine health and seasonal summer stress as factors contributing to reduced herd fertility. Furthermore, programmes of timed insemination provide a platform to evaluate efficacy of nutritional and herd health systems targeted to the transition and post-partum periods. The homeorhetic periparturient period, as cows deal with decreases in dry matter intake, results in a negative energy balance and is associated with a period of immunosuppression. Cows that transition well will cycle earlier and have a greater risk of becoming pregnant earlier post-partum. The innate arms of the immune system (acute and adaptive) are suppressed during the periparturient period. Cows experiencing the sequential complex of disorders such as dystocia, puerperal metritis, metritis, endometritis and subclinical endometritis are subsequently less fertile. Targeted strategies of providing specific nutraceuticals that provide pro- and anti-inflammatory effects, such as polyunsaturated fatty acids (e.g., linoleic, eicosapentaenoic/docosahexaenoic, conjugated linoleic acid), sequential glycogenic and lipogenic enrichment of diets, and organic selenium appear to differentially regulate and improve the immune and reproductive systems to benefit an earlier restoration of ovarian activity and increased fertility. © 2010 Blackwell Verlag GmbH.

Purpose Retinitis Pigmentosa (RP) is a progressive neurodegenerative disease resulting in blindness for which there is no current treatment. While the members of the family of RP diseases differ in etiology, their outcomes are the same: apoptosis of rods followed by cones. Recently, the bile acid, tauroursodeoxycholic acid (TUDCA), has been shown to have anti-apoptotic properties in neurodegenerative diseases, including those of the retina. In this study we examine the efficacy of TUDCA on preserving rod and cone function and morphology at post-natal day 30 (P30) in the rd10 mouse, a model of RP. Methods Wild-type C57BL/6J and rd10 mice were systemically injected with TUDCA (500 mg/kg) every three days from P6-P30 and compared to vehicle (0.15M NaHCO3). At P30, retinal function was measured with electroretinography (ERG) and morphological preservation of the rods and cones assessed with immunohistochemistry. Results Dark-adapted ERG responses were two-fold greater in rd10 mice treated with TUDCA compared to vehicle, while light-adapted responses were two-fold larger in TUDCA-treated mice compared to controls, at the brightest ERG flash intensities. TUDCA-treated rd10 retinas had five-fold more photoreceptors than vehicle-treated. TUDCA treatments did not alter retinal function or morphology of wild-type mice when administered to age-matched mice. Conclusions TUDCA is efficacious and safe in preserving vision in the rd10 mouse model of RP when treated between P6 and P30. At P30, a developmental stage at which nearly all rods are absent in the rd10 mouse model of RP, TUDCA treatment preserved both rod and cone function and greatly preserved overall photoreceptor numbers.

To develop a comprehensive measure of Early Physical Functioning (EPF) post-stroke quantified through Rasch analysis and conceptualized using the International Classification of Functioning Disability and Health (ICF). An observational cohort study. A cohort of 262 subjects (mean age 71.6 (standard deviation 12.5) years) hospitalized post-acute stroke. Functional assessments were made within 3 days of stroke with items from valid and reliable indices commonly utilized to evaluate stroke survivors. Information on important variables was also collected. Principal component and Rasch analysis confirmed the factor structure, and dimensionality of the measure. Rasch analysis combined items across ICF components to develop the measure. Items were deleted iteratively, those retained fit the model and were related to the construct; reliability and validity were assessed. A 38-item unidimensional measure of the EPF met all Rasch model requirements. The item difficulty matched the person ability (mean person measure: -0.31; standard error 0.37 logits), reliability of the person-item-hierarchy was excellent at 0.97. Initial validity was adequate. The 38-item EPF measure was developed. It expands the range of assessment post acute stroke; it covers a broad spectrum of difficulty with good initial psychometric properties that, once revalidated, can assist in planning and evaluating early interventions.

The aim of this study was to explore the methods, processes and strategies used by early childhood education and care (ECEC) services when determining the nutritional adequacy of food provided to children in their care. Semi-structured interviews (n = 22) were conducted with directors, educators and cooks at long day care services (LDCS) (n = 12) regarding nutritional adequacy, the use of tools, guidelines and checklists, menu planning and identification and management of unhealthy foods. A qualitative thematic approach was used to identify anticipated and emergent themes. Case-by-case comparisons were then made, and tables and models were created to allow for comparative analysis. LDCS relied on personal knowledge, experience and 'common sense' when determining the nutritional adequacy of the food provided to children. LDCS demonstrated a lack of awareness and use of current regulatory requirements, nutrition guidelines and recommendations, although the services were confident in providing nutrition advice to parents/carers. LDCS staff use personal knowledge and experience over evidence-based nutrition guidelines and recommendations when determining if the food provided to children is nutritionally adequate. ECEC services are recognised as important settings for obesity prevention and the development of lifetime healthy eating habits. This study highlights the complexities and inconsistencies in providing food that is nutritious and appropriate to children in care while highlighting the need to improve the use and accessibility of nutrition guidelines. © 2016 Dietitians Association of Australia.

Since 1990, the lives of 48 million children under the age of 5 years have been saved because of increased investments in reducing child mortality. However, despite these unprecedented gains, 250 million children younger than 5 years in low- and middle-income countries (LMIC) cannot meet their developmental potential due to poverty, poor health and nutrition, and lack of necessary stimulation and care. Lesotho has high levels of poverty, HIV, and malnutrition, all of which affect child development outcomes. There is a unique opportunity to address these complex issues through the widespread network of informal preschools in rural villages in the country, which provide a setting for inclusive, integrated Early Childhood Care and Development (ECCD) and HIV and nutrition interventions. We are conducting a cluster randomised controlled trial in Mokhotlong district, Lesotho, to evaluate a newly developed community-based intervention program to integrate HIV-testing and treatment services, ECCD, and nutrition education for caregivers with children aged 1-5 years living in rural villages. Caregivers and their children are randomly assigned by village to intervention or control condition. We select, train, and supervise community health workers recruited to implement the intervention, which consists of nine group-based sessions with caregivers and children over 12 weeks (eight weekly sessions, and a ninth top-up session 1 month later), followed by a locally hosted community health outreach day event. Group-based sessions focus on using early dialogic book-sharing to promote cognitive development and caregiver-child interaction, health-related messages, including motivation for HIV-testing and treatment uptake for young children, and locally appropriate nutrition education. All children aged 1-5 years and their primary caregivers living in study villages are eligible for participation. Caregivers and their children will be interviewed and assessed at baseline, after

Retinopathy of prematurity(ROP) is the most common serious ophthalmic disease in preterm infants. Human milk may provide a protective effect for ROP; however, beneficial effects of human milk preclude randomized trials. Therefore, we conducted a retrospective analysis comparing early postnatal nutrition with ROP development. Evaluate relationship between early postnatal nutriture and ROP surgery. Nutrition data was collected for inborn AGA infants, BW 700-1000 g. ROP surgery was the primary outcome variable. A single pediatric ophthalmologist supervised examinations. All infants received triweekly IM vitamin A as chronic lung disease prophylaxis (Tyson: NEJM, 1999). BW and gestational age were 867+/-85 g and 26.3+/-1.2 weeks (n=77, mean+/-1SD). ROP surgery infants(n=11) received more parenteral nutrition, 1648 mL, and less human milk, 13.8 mL/kg-day, and vitamin E, 1.4 mg/kg-day, during the second postnatal week. Human milk was a negative predictor for ROP surgery, odds ratio=0.94. Both groups met vitamin A recommendations; however, 74% was administered via IM injections. Neither group met vitamin E recommendations. Human milk feeding, parenteral nutrition volume and vitamin E intake were predictors for ROP surgery. IM vitamin A injections provided the majority of vitamin A; vitamin E administration was insufficient. Improving human milk feeding rates and vitamin dosing options may affect ROP surgery rates.

Long-term consequences of nutrition and growth in early childhood and possible preventive interventions.

Adair, Linda S

2014-01-01

Maternal nutritional deficiencies and excesses during pregnancy, and faster infant weight gain in the first 2 years of life are associated with increased risk of noncommunicable diseases (NCDs) in adulthood. The first 1,000 days of life (from conception until the child reaches age 2 years) represent a vulnerable period for programming of NCD risk, and are an important target for prevention of adult disease. This paper takes a developmental perspective to identify periconception, pregnancy, and infancy nutritional stressors, and to discuss mechanisms through which they influence later disease risk with the goal of informing age-specific interventions. Low- and middle-income countries need to address the dual burden of under- and overnutrition by implementing interventions to promote growth and enhance survival and intellectual development without increasing chronic disease risk. In the absence of good evidence from long-term follow-up of early life interventions, current recommendations for early life prevention of adult disease presume that interventions designed to optimize pregnancy outcomes and promote healthy infant growth and development will also reduce chronic disease risk. These include an emphasis on optimizing maternal nutrition prior to pregnancy, micronutrient adequacy in the preconception period and during pregnancy, promotion of breastfeeding and high-quality complementary foods, and prevention of obesity in childhood and adolescence. © 2014 Nestec Ltd., Vevey/S.

We investigated the relationships among early childhood caries (ECC), mouth pain, and nutritional status in children aged 1 to 6 years in Southern and Central Vietnam. A total of 593 parent-child pairs were recruited from 5 kindergartens or preschools in Ho-Chi Minh City and Da Nang. Parents completed surveys about dietary habits, oral health practices, and children's mouth pain experience; children received anthropometric assessment and dental examinations. There was a high prevalence of dental caries (74.4%), mostly untreated, and mouth pain (47.1%). Moderate correlations were found between parents' and children's consumption of soda (ρ = 0.361; P < .001) and salty snacks (ρ = 0.292; P < .001). Severity of ECC was associated with decreased weight- and body mass index-for-age z-scores. Presence of pulp-involved caries was associated with strikingly lower height-for-age (mean difference = 0.66; P = .001), weight-for-age (mean difference = 1.17; P < .001), and body mass index-for-age (mean difference = 1.18; P < .001) z-scores. Mouth pain was associated with lower body mass index-for-age z-scores (mean difference = 0.29; P = .013). ECC might negatively affect children's nutritional status, which might be mediated by the depth of decay, chronic inflammation, and mouth pain. Family-based and prevention-oriented nutrition and oral health programs are needed and should start during pregnancy and infancy.

Growth factors play critical role in cell proliferation, regulate tissue differentiation and modulate organogenesis. Several growth factors have been identified in the testes of various mammalian species in last few years. In present investigation, the objective was to determine the expression of epidermal growth factor (EGF) and the epidermal growth factor receptor (EGFR) in yak testicular tissue by relative quantitative real time polymerase chain reaction (RT-PCR), Western blot (WB) and immunohistochemistry (IHC) from mRNA and protein levels. The testicular tissues were collected from male yak at 6 and 24 months old. Results of RT-PCR and WB showed that the expression quantity of EGF and EGFR at 24 months of age was higher than at 6 months, and the increase rate of EGFR on mRNA and protein levels was higher than the increase rate EGF during post-natal testes development. Positive staining for EGF and EGFR was very low and mainly localized to Leydig cells testes at 6 months of age with immunohistochemistry, and seminiferous tubules were not observed. At 24 month of age, both the EGF and EGFR could be detected in Leydig cells, peritubular myoid cells, sertoli cells and germ cells of the yak testes. However, EGF and EGFR were localized to preferential adluminal compartment and basal compartment in the seminiferous tubules, respectively. In conclusion, the findings in present studies suggest that EGF and EGFR as important paracrine and/or autocrine regulators in yak testes development and spermatogenesis. © 2014 Blackwell Verlag GmbH.

Disease related malnutrition (DRM) is highly prevalent in Spain, affecting 23% of in-hospital patients, and is associated with clinical complications. Specialized nutritional support (SNS) can reduce these complications. Prospective study carried out in standard clinical practice conditions to test if SNS during the first 5 days of hospitalization, or subsequently, was associated to a lower length of stay or reduced complications in patients with a NRS-2002 score≥3 points. In the group of patients who initiated early SNS, the length of stay was 8.83 days shorter than in the group with a later introduction (95% CI 3.55-14.10); nevertheless, the higher prevalence of male and oncological patients in this group could have impacted the results. A tendency towards a statistically significant lower mortality rate and a reduced amount of total complications was described. The early introduction of SNS (within the first 5 days of hospitalization) in patients with DRM was associated with a 32.4% reduction in the length of stay. Copyright © 2016 Elsevier España, S.L.U.

It is estimated that more than 90% of head and neck cancer (HNC) survivors who underwent chemoradiotherapy experience one or more nutrition impact symptoms (NIS) in the months or years thereafter. Despite the high prevalence, there is limited research addressing long-term impact of NIS on outcomes such as nutrition and quality of life in HNC survivors treated with chemoradiotherapy. To conduct a systematic review of the literature pertaining to the presence of nutrition impact symptoms and their associated outcomes in post-chemoradiotherapy head and neck cancer survivors. A systematic review was conducted across three databases according to PRISMA guidelines and used to identify current literature regarding NIS in HNC survivors. A keyword search was conducted in PubMed, Scopus, and Web of Science from 2007 to 2017. Studies that met all of the following criteria were included in the review: (1) studies must include human subjects with a HNC diagnosis; (2) study participants must have received chemoradiotherapy; (3) study participants must have been post-treatment for a minimum of 3 months at the time of data collection; (4) full-text articles must have appeared in peer-reviewed journals; (5) papers must have been published in English; (6) studies must be quantitative in nature; (7) studies must have reported at least one NIS; and (8) studies must address at least one of the following outcomes: nutrition, functional status, or quality of life. Two independent reviewers assessed study quality using a predefined set of criteria. A systematic search yielded 1119 papers, of which 15 met the inclusion criteria. The study reviewed existing evidence of NIS in a variety of HNC survivors ranging from 3 months to greater than 10 years post-chemoradiotherapy treatment. Eight hundred forty-nine study participants were included in the review. Of the 15 studies, 10 were designed as prospective cohort studies, 4 were cross-sectional studies, and 1 was a retrospective cohort

Early childbearing influences women's health. This study aims to examine the effects of socio-demographic factors on nutritional status of early childbearing mothers in Bangladesh based on Body Mass Index (BMI) as the indicator. Data was extracted from Bangladesh Demographic and Health Survey (BDHS)-2011. The survey was performed on 17,842 married women aged 15-49. We focused on early childbearing mothers (age ≤ 24, and who had delivered their first child ≤ 20). Mothers who were underweight (BMI ≤ 18.5 kg/m(2)) would be further classified into various grades of chronic energy deficiency (CED): mild (17.0 ≤ BMI < 18.5 kg/m(2)), moderate (16.0 ≤ BMI <17.0 kg/m(2)), and severe (BMI < 16.0 kg/m(2)). Multiple logistic regression model was used to examine the effect of socio-demographic factors on nutritional status. Mean age of the mothers was 20.49 ± 2.37 years (ranged 15-24 years). The prevalence of underweight among early childbearing mothers was 32.1 % (urban 25 % and rural 35.1 %). Most of the underweight mothers had mild (62.2 %) CED, while the remaining had either moderate (25.9 %) or severe (11.9 %) CED. Multiple logistic regression analysis demonstrated that young mothers from rural areas, poor families, and those who were illiterate or with low level of education, working, and married to unemployed husband were at higher risk for being underweight. Young mothers who had non-caesarean delivered, delivered at home, or married at early age and had more than two children were also at higher risk for being underweight. The prevalence of underweight among early childbearing mothers in Bangladesh is very high (32.1 %), associated with the still common practice of teenage marriage. Education level, wealth index, occupation, place of residence, age at first marriage and parity were important predictors for their nutritional status. The government and non-government organizations should take initiatives to reduce

Nutritional conditions in the pre-gestacional period and during pregnancy were evaluated in 372 pregnant women based on the body mass index and Rosso's Graph. Approximately half (51%) the pregnant women presented normal pre-gestacional weight; however, 17.7% were underweight and 31.3% overweight. In the third trimester, 18.8% were underweight and 28.2% overweight. The weight at birth increased as nutritional conditions during pregnancy improved. These results show the importance of appropriate anthropometric control in order to prevent a bad neonatal prognosis and reaffirms the importance of such activity during the whole routine of pre-natal control.

Combined enteral and parenteral nutrition.

To review and discuss the evidence and arguments to combine enteral nutrition and parenteral nutrition in the ICU, in particular with reference to the Early Parenteral Nutrition Completing Enteral Nutrition in Adult Critically Ill Patients (EPaNIC) study. The EPaNIC study shows an advantage in terms of discharges alive from the ICU when parenteral nutrition is delayed to day 8 as compared with combining enteral nutrition and parenteral nutrition from day 3 of ICU stay. The difference between the guidelines from the European Society of Enteral and Parenteral Nutrition in Europe and American Society for Parenteral and Enteral Nutrition/Society of Critical Care Medicine in North America concerning the combination of enteral nutrition and parenteral nutrition during the initial week of ICU stay was reviewed. The EPaNIC study clearly demonstrates that early parenteral nutrition in the ICU is not in the best interests of most patients. Exactly at what time point the combination of enteral nutrition and parenteral nutrition should be considered is still an open question.

Early recognition of and intervention for nutritional disorders may help prevent functional disability and mortality in elderly patients. Prevention of nutritional disorders in older adults is often multidimensional and may require multidisciplinary collaboration. Proactive education of the older adult, early recognition of nutritional deficiencies, and rectification of the nutritional disorders are the keys to achieving ideal nutritional status in elders and enabling them to achieve successful aging.

It has been recently shown that enriched environment led to a significant benefit in learning and retention of visual-spatial memory, being able to reverse the cognitive impairment generated by undernourishment and recurrent seizures. We investigated the hippocampal morphological effects of recurrent seizures and undernourishment early in life in Wistar rats and the possible benefits produced by the enriched environment in these conditions. The morphological parameters stereologically evaluated were hippocampal volume, thickness of pyramidal stratum of the CA1 subfield and neuronal and glial densities in the same subfield. Male Wistar rats were divided into eight groups including nourished, nourished+enriched environment, nourished+recurrent seizures, nourished+recurrent seizures+enriched environment, undernourished, undernourished+enriched environment, undernourished+recurrent seizures and undernourished+recurrent seizures+enriched environment. Undernourishment model consisted in nutritional deprivation regimen from post-natal day 2 (P2) to P15. From P8 to P10, recurrent seizures group were induced by flurothyl three times per day. Enriched environment groups were exposed between P21 and P51. Our main findings were: (1) animals submitted to the enriched environment showed an increased hippocampal volume; (2) enriched environment promotes increases in the thickness of the pyramidal layer in hippocampal CA1 subfield in animals nourished and undernourished with recurrent seizures; (3) undernourishment during early development decreased neuronal density in CA1 and CA3 subfields. Our findings show that these three conditions induces important changes in hippocampal morphology, the most deleterious changes are induced by undernourishment and recurrent seizures, while more beneficial morphological changes are produced by enriched environment.

Post-operative management in gastrointestinal (GI) surgery is becoming well established with 'Enhanced Recovery After Surgery' protocols starting 24 hours prior to surgery with carbohydrate loading and early oral or enteral feeding given to patients the first day following surgery. However, whether or not nutritional intervention should be initiated earlier in the preoperative period remains unclear. Poor pre-operative nutritional status has been linked consistently to an increase in post-operative complications and poorer surgical outcome. To review the literature on preoperative nutritional support in patients undergoing gastrointestinal surgery (GI). The searches were initially run in March 2011 and subsequently updated in February 2012. Databases including all EBM Reviews (Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA and NHSEED) MEDLINE, EMBASE, AMED, British Nursing Index Archive using OvidSP were included and a search was run on each database separately after which duplicates were excluded. The inclusion criteria were randomised controlled trials that evaluated pre-operative nutritional support in GI surgical participants using a nutritional formula delivered by a parenteral, enteral or oral route. The primary outcomes included post-operative complications and length of hospital stay. Two observers screened the abstracts for inclusion in the review and performed data extraction. Bias was assessed for each of the included studies using the bias assessment tables in the Cochrane Software Review Manager (version 5.1, Cochrane Collaboration). The trials were analysed using risk ratios with Mantel-Haenszel in fixed effects methods displayed with heterogeneity. Meta-analyses were undertaken on trials evaluating immune enhancing (IE) nutrition, standard oral supplements, enteral and parenteral nutrition (PN) which were administered pre-operatively.Study characteristics were summarised in tables.

This study investigated the effects of a sport nutrition education intervention (SNEI) on dietary intake, knowledge, body composition, and performance in NCAA Division I baseball players. Resistance trained NCAA Division I baseball players (82.4 ± 8.2 kg; 1.83 ± 0.06 m; 13.7 ± 5 % body fat) participated in the study during 12 weeks of off-season training. Fifteen players volunteered for SNEI while 15 players matched for position served as controls (C) for body composition and performance. The nutrition intervention group (NI) received a 90 min SNEI encompassing energy intake (Kcal), carbohydrate (CHO), protein (PRO), fat, food sources, and hydration. Sport nutrition knowledge questionnaires were administered to NI pre and post. Nutritional status was determined by three-day dietary logs administered to NI pre and post. Body composition and performance (5-10-5 shuttle test, vertical jump, broad jump, 1 RM squat) were measured pre and post for C and NI. Knowledge increased in NI. Pro and fat, but not CHO intake increased in NI. FM decreased pre to post in NI (11.5 ± 4.8 vs. 10.5 ± 5.4 kg) but not C (11.3 ± 4.7 vs. 11.9 ± 4.5 kg). FFM increased pre to post with no differences between groups. The 5-10-5 shuttle times decreased significantly more in NI (4.58 ± 0.15 vs. 4.43 ± 0.13 sec) compared to C (4.56 ± 0.18 vs. 4.50 ± 0.16 sec). Jump and squat performance increased pre to post with no differences between groups. Our findings indicate that an off season SNEI is effective at improving sport nutrition knowledge and some, but not all, nutrient intakes and performance measures in Division I baseball players. Key points Sport nutrition education intervention increased nutritional knowledge and nutritional status. Sport nutrition education intervention reduced body fat percentage, total fat mass, 5-10-5 shuttle times, and trended towards greater increases in lean mass compared to controls. Both groups increased strength and jump ability similarly. PMID:28344452

Early versus delayed post-operative bathing or showering to prevent wound complications.

Many people undergo surgical operations during their life-time, which result in surgical wounds. After an operation the incision is closed using stiches, staples, steri-strips or an adhesive glue. Usually, towards the end of the surgical procedure and before the patient leaves the operating theatre, the surgeon covers the closed surgical wound using gauze and adhesive tape or an adhesive tape containing a pad (a wound dressing) that covers the surgical wound. There is currently no guidance about when the wound can be made wet by post-operative bathing or showering. Early bathing may encourage early mobilisation of the patient, which is good after most types of operation. Avoiding post-operative bathing or showering for two to three days may result in accumulation of sweat and dirt on the body. Conversely, early washing of the surgical wound may have an adverse effect on healing, for example by irritating or macerating the wound, and disturbing the healing environment. To compare the benefits (such as potential improvements to quality of life) and harms (potentially increased wound-related morbidity) of early post-operative bathing or showering (i.e. within 48 hours after surgery, the period during which epithelialisation of the wound occurs) compared with delayed post-operative bathing or showering (i.e. no bathing or showering for over 48 hours after surgery) in patients with closed surgical wounds.

During the early post-natal phases the brain is experience-seeking and provided by a considerable plasticity which allows a fine tuning between the external environment and the developing organism. Since the early work of Seymour Levine, an impressive amount of research has clearly shown that stressful experiences exert powerful effects on the brain and body development. These effects can last throughout the entire life span influencing brain function and increasing the risk for depression and anxiety disorders. The mechanisms underlying the effects of early stress on the developing organism have been widely studied in rodents through experimental manipulations of the post-natal environment, such as handling, which have been shown to exert important effects on the emotional phenotype and the response to stress. In the present paper we review the relevant literature and present some original data indicating that, compared to handling, which imposes an external manipulation on the mother-infant relationship, social enrichment, in the form of communal rearing, in mice has very profound effects on animal's emotionality and the response to stress. These effects are also accompanied by important changes in central levels of brain-derived neurotrophic factor. The present data indicate that communal rearing has more pervasive effects than handling, strengthening previous data suggesting that it is a good animal model of reduced susceptibility to depression-like behavior. Overall, the availability of ever more sophisticated animal models represents a fundamental tool to translate basic research data into appropriate interventions for humans raised under traumatic or impoverished situations.

Glycolytic activity during the transition period from anaerobic to aerobic metabolism has been demonstrated to be critical for heart recovery in isolated reperfused hearts. The purpose of this work was to investigate the relevance of the glycolytic pathway in preserving the cardiac function of post-conditioned hearts. The activation of the glycolytic pathway in post-conditioned hearts was evaluated by measuring GLUT-4 insertion, glucose consumption and lactate production. Iodoacetic acid and 2-deoxy-D-glucose were administrated to the working hearts to evaluate the effect of glycolytic inhibition in the post-conditioning protective effect. Post-conditioning maneuvers applied to isolated rat hearts, after prolonged ischemia and before reperfusion, promoted recovery of cardiac mechanical function with sustained increase of GLUT-4 translocation and activation of the glycolytic pathway during ischemia and early reperfusion. Iodoacetate inhibited the protective effect of post-conditioning, without affecting the mitochondrial oxidative capacity. Glycolysis contribution to maintain mechanical function at early reperfusion was observed in post-conditioned hearts perfused with 2-deoxy-D-glucose and in hearts in which iodoacetate was administered only during reperfusion. It is concluded that in the post-conditioned heart, a functional compartmentation of anaerobic energy metabolism, at early reperfusion, plays a significant role in cardiac protection against reperfusion damage.

Benthic diatoms constitute the primary diet of abalone during their early stages of development. To evaluate the dietary preferences of early post-larval abalone, Haliotis diversicolor supertexta, we analyzed the gut contents of post-larvae that settled on diatom films. We compared the abundance and species diversity of diatom assemblages in the gut to those of the epiphytic diatom assemblages on the attachment films, and identified 40 benthic diatom species in the gut contents of post-larvae 12 to 24 d after settlement. The most abundant taxa in the gut contents were Navicula spp., Amphora copulate, and Amphora coffeaeformis. Navicula spp. accounted for 64.0% of the cell density. In the attachment films, we identified 110 diatom species belonging to 38 genera. Pennate diatoms were the dominant members including the species Amphiprora alata, Cocconeis placentula var. euglypta, Cylindrotheca closterium, Navicula sp. 2, and A. coffeaeformis. Nano-diatoms (<20 μm in length) accounted for a considerable proportion of the total species number and cell density of the diatom assemblages in the gut contents and on the films. This suggests that nano-diatoms are important to the efficient production of abalone seed. The difference of the composition and abundance of diatoms between in the guts and on the biofilms suggests that early post-larval grazing was selective. An early post-larval abalone preferred nano-diatoms and the genera Navicula and Amphora during the month after settlement.

Lifecourse studies suggest that the metabolic syndrome (MetS) may be rooted in the early life environment. This study aims to examine the pathways linking early nutritional and psychosocial exposures and the presence of MetS in midlife. Data are from the National Child Development Study including individuals born during 1 week in 1958 in Great Britain and followed-up until now. MetS was defined based on the National Cholesterol Education Program Adult Treatment Panel III classification. Mother's pre-pregnancy body mass index (BMI) was used as a proxy of the early nutritional environment and Adverse Childhood Experiences (ACE) as a proxy for early psychosocial stress. Socioeconomic characteristics, pregnancy and birth conditions were extracted as potential confounders. Adult health behaviors, BMI, socioeconomic environment and psychological state were considered as mediating variables. Multivariate models were performed by including variables sequentially taking a lifecourse approach. 37.5 % of men and 19.8 % of women had MetS. Participants with an obese/overweight mother presented a higher risk of MetS than those whose mother had a normal pre-pregnancy BMI. Men exposed to two ACE or more, and women exposed to one ACE, were more at risk of MetS compared to unexposed individuals. After including confounders and mediators, mother's pre-pregnancy BMI was still associated with MetS in midlife but the association was weakened after including participant's adult BMI. ACE was no longer associated with MetS after including confounders in models. The early nutritional environment, represented by mother's pre-pregnancy BMI, was associated with the risk of MetS in midlife. An important mechanism involves a mother-to-child BMI transmission, independent of birth or perinatal conditions, socioeconomic characteristics and health behaviors over the lifecourse. However this mechanism is not sufficient for explaining the influence of mother's pre-pregnancy BMI which implies the

Heart transplant is the golden standard in the management of end-stage heart failure. Recent studies have pointed out the role of nutritional issues in patients evaluated for heart transplant listing. In particular, extremes in body habitus, cachexia and obesity, have been characterized and identified as independent prognostic factors and clinically relevant target for therapeutic interventions. Effects of such conditions exert a prognostic implication well beyond waiting time up to early post transplant setting. Changes in posttransplant clinical conditions and nutritional status have been recently described in their pattern of presentation and implications on weight gain, reversal of preoperative cachexia and early and late morbidity and mortality. New onset diabetes mellitus and metabolic syndrome have been disclosed as relevant clinical conditions in this setting. Implications for tailoring of immunosuppressive therapy and dietary prescription emerged as main stem of long term recipient management. All this issues have been reviewed focusing on the clinical relevance of this growing body of knowledge and emphasizing the role of a multidisciplinary approach for selection and management of heart transplant recipients.

Even though it is widely recognized that early childhood development (ECD) is one of the most important predictors of future social capital and national productivity, the recently published ECD Lancet Series reports that about 250 million children under 5 years are at risk of not reaching their developmental potential, mainly as a result of poverty and social injustice. So why is this and what will it take to reverse this situation? The purpose of this special issue is to highlight important contributions from previously published articles in Maternal & Child Nutrition to the field of nutrition and ECD. The collection of papers presented in this special issue collectively indicates that although nutrition-specific interventions are essential for child development, they are not sufficient by themselves for children to reach their full developmental potential. This is because ECD is influenced by many other factors besides nutrition, including hand washing/sanitation, parenting skills, psychosocial stimulation, and social protection. Future research should focus on mixed-methods implementation science seeking to understand how best to translate evidence-based integrated ECD packages into effective intersectoral policies and programs on a large scale. In addition to health and nutrition, these programs need to consider and include responsive parenting (including responsive feeding), learning stimulation, education, and social protection. Future studies should also address if and how childhood obesity affects human physical, socioemotional, and cognitive development. © 2016 John Wiley & Sons Ltd.

A mechanism generating a natal-neutron-star kick and involving only standard neutrinos is discussed. In this mechanism, the neutrino effect on the plasma of the supernova-core envelope in a magnetorotational explosion accompanied by the generation of a strong toroidal magnetic field leads to a redistribution of the magnetic field B in the 'upper' and 'lower' hemispheres of the supernova-core envelope. The emerging asymmetry of the magnetic-field pressure may generate a natal-pulsar kick.

Adolescence is the period of development that begins at puberty and ends in early adulthood. Most commonly, adolescence is divided into three developmental periods: early adolescence (10-14 years of age), late adolescence (15-19 years of age), and young adulthood (20-24 years of age). Adolescence is marked by physical and sexual maturation, social and economic independence, development of identity, acquisition of skills needed to carry out adult relationships and roles, and the capacity for abstract reasoning. Adolescence is characterized by a rapid pace of growth that is second only to that of infancy. Nutrition and the adolescent transition are closely intertwined, since eating patterns and behaviors are influenced by many factors, including peer influences, parental modeling, food availability, food preferences, cost, convenience, personal and cultural beliefs, mass media, and body image. Here, we describe the physiology, metabolism, and nutritional requirements for adolescents and pregnant adolescents, as well as nutrition-related behavior and current trends in adolescent nutrition. We conclude with thoughts on the implications for nutrition interventions and priority areas that would require further investigation. © 2017 New York Academy of Sciences.

Receiving an education is essential for children living in poverty to fulfil their potential. Success in the early years of schooling is important as children who repeat grade one are particularly at risk for future dropout. We examined early life factors associated with grade repetition through logistic regression and explored reasons for repeating a grade through parent report. In 2012-2014 we re-enrolled children aged 7-11 years in rural KwaZulu-Natal who had been part of an early life intervention. Of the 894 children included, 43.1% had repeated a grade, of which 62.9% were boys. Higher maternal education (aOR 0.44; 95% CI 0.2-0.9) and being further along in the birth order (aOR 0.46; 95% CI 0.3-0.9) reduced the odds of grade repetition. In addition, maternal HIV status had the strongest effect on grade repetition for girls (aOR 2.17; 95% CI 1.3-3.8), whereas for boys, it was a fridge in the household (aOR 0.59; 95% CI 0.4-1.0). Issues with school readiness was the most common reason for repeating a grade according to parental report (126/385, 32.7%), while school disruptions was an important reason among HIV-exposed boys. Further research is needed to elucidate the pathways through which HIV affects girls' educational outcomes and potentially impacts on disrupted schooling for boys. Our results also highlight the importance of preparation for schooling in the early years of life; future research could focus on gaining a better understanding of mechanisms by which to improve early school success, including increased quality of reception year and investigating the protective effect of older siblings.

To assess the feasibility, findings and potential value of early post-interventional, contrast-enhanced ultrasonographic (CEUS) study of prostate artery embolization (PAE). Fourteen patients treated with PAE for symptomatic benign prostatic hyperplasia were prospectively included in the study. Sonographic evaluation of the prostate included: 1) baseline transabdominal and transrectal CEUS (ta-CEUS and tr-CEUS, respectively) 1-3 days prior to PAE; 2) early post PAE CEUS, with ta-CEUS immediately post PAE and tr-CEUS 3 days post PAE; and 3) follow-up with ta-CEUS and tr-CEUS 3 months post PAE. A brief unenhanced US study preceded each CEUS. Post-therapeutic changes in size, echogenicity and enhancement of the prostate were recorded and were correlated with clinical outcomes. PAE resulted in clinical success in 11/14 patients (78.5%). All sonographic studies were technically adequate, with the exception of ta-CEUS immediately post PAE in 2/14 (14.2%) patients. CEUS studies immediately post PAE and 3 days post PAE showed non-enhancing, welldefined infarctions of the prostate in 10/14 patients (71.4%). There was a strong correlation between ta-CEUS immediately post PAE and tr-CEUS 3 days post PAE regarding the measurements of prostatic infarctions (r =0.98, p< 0.01). The presence of infarctions on early post PAE CEUS was associated with clinical success (p=0.01) and their extent correlated with the degree of prostate shrinkage on 3-month follow-up (r=0.84, p<0.05). The 3 cases of failed PAE showed no infarctions and no prostate shrinkage. Early post-interventional CEUS of PAE is feasible and may have clinical and prognostic value.

Objective Controversy exists over the utility of early post-operative magnetic resonance imaging (MRI) after transsphenoidal pituitary surgery for macroadenomas. We investigate whether valuable information can be derived from current higher resolution scans. Methods Volumetric MRI scans were obtained in the early (<10 days) and late (>30 days) post-operative periods in a series of patients undergoing transsphenoidal pituitary surgery. The volume of the residual tumor, resection cavity, and corresponding visual field tests were recorded at each time point. Statistical analyses of changes in tumor volume and cavity size were calculated using the late MRI as the gold standard. Results 40 patients met the inclusion criteria. Pre-operative tumor volume averaged 8.8 cm3. Early postoperative assessment of average residual tumor volume (1.18 cm3) was quite accurate and did not differ statistically from late post-operative volume (1.23 cm3, p=.64), indicating the utility of early scans to measure residual tumor. Early scans were 100% sensitive and 91% specific for predicting ≥ 98% resection (p<.001, Fisher’s exact test). The average percent decrease in cavity volume from pre-operative MRI (tumor volume) to early post-operative imaging was 45% with decreases in all but 3 patients. There was no correlation between the size of the early cavity and the visual outcome. Conclusions Early high resolution volumetric MRI is valuable in determining the presence or absence of residual tumor. Cavity volume almost always decreases after surgery and a lack of decrease should alert the surgeon to possible persistent compression of the optic apparatus that may warrant re-operation.

To develop a practical, efficient and predictive algorithm to manage potential or actual post-operative hypocalcaemia after complete thyroidectomy, using a single post-operative parathyroid hormone assay. This paper reports a prospective study of 59 patients who underwent total or completion thyroidectomy over a period of 24 months. Parathyroid hormone levels were checked post-operatively on the day of surgery, and all patients were evaluated for hypocalcaemia both clinically and biochemically with serial corrected calcium measurements. No patient with an early post-operative parathyroid hormone level of 23 ng/l or more (i.e. approximately twice the lower limit of the normal range) developed hypocalcaemia. All the patients who initially had post-operative hypocalcaemia but had an early parathyroid hormone level of 8 ng/l or more (i.e. approximately two-thirds of the lower limit of the normal range) had complete resolution of their hypocalcaemia within three months. Early post-operative parathyroid hormone measurement can reliably predict patients at risk of post-thyroidectomy hypocalcaemia, and predict those patients expected to recover from temporary hypocalcaemia. A suggested post-operative management algorithm is presented.

Review: The effect of nutrition on timing of pubertal onset and subsequent fertility in the bull.

PubMed

Kenny, D A; Byrne, C J

2018-06-01

The advent of genomic selection has led to increased interest within the cattle breeding industry to market semen from young bulls as early as possible. However, both the quantity and quality of such semen is dictated by the age at which these animals reach puberty. Enhancing early life plane of nutrition of the bull stimulates a complex biochemical interplay involving metabolic and neuroendocrine signalling and culminating in enhanced testicular growth and development and earlier onset of sexual maturation. Recent evidence suggests that an enhanced plane of nutrition leads to an advancement of testicular development in bulls at 18 weeks of age. However, as of yet, much of the neuronal mechanisms regulating these developmental processes remain to be elucidated in the bull. While early life nutrition clearly affects the sexual maturation process in bulls, there is little evidence for latent effects on semen traits post-puberty. Equally the influence of prevailing nutritional status on the fertility of mature bulls is unclear though management practices that result in clinical or even subclinical metabolic disease can undoubtedly impact upon normal sexual function. Dietary supplements enriched with various polyunsaturated fatty acids or fortified with trace elements do not consistently affect reproductive function in the bull, certainly where animals are already adequately nourished. Further insight on how nutrition mediates the biochemical interaction between neuroendocrine and testicular processes will facilitate optimisation of nutritional regimens to optimise sexual maturation and subsequent semen production in bulls.

Effects of maternal anthropometrics on pregnancy outcomes in South Asian women: a systematic review.

2018-04-01

This systematic review investigates associations between maternal pre-pregnancy/early-pregnancy anthropometrics (e.g. weight and body fat), anthropometric change and pregnancy outcomes in South Asian and White women. Twelve electronic literature databases, reference lists and citations of all included studies were searched. Observational studies published in the English language were included. Descriptive synthesis was used to summarize the evidence base. Twenty-two studies met the inclusion criteria (403,609 births [351,856 White and 51,753 South Asian]). Nine were prospective cohort studies, nine were retrospective cohort studies and two were cross-sectional studies. Results suggested that in South Asian women, maternal pre-pregnancy/early-pregnancy anthropometrics were associated with anthropometric change, birthweight, mode of delivery and gestational diabetes mellitus (GDM). Gestational anthropometric change was found to be associated with GDM. There was limited evidence to suggest that there may be associations between maternal pre-anthropometrics/early anthropometrics and hypertensive disorders, stillbirth, congenital anomalies, post-natal weight retention and post-natal impaired glucose tolerance. The evidence suggested a combined effect of pre-pregnancy/early-pregnancy anthropometrics and gestational anthropometric change on both GDM and post-natal weight retention. The increased risk of adverse pregnancy outcomes in South Asian women should be considered in guidelines for weight management before and during pregnancy. © 2018 The Authors.

Affinity for natal environments by dispersers impacts reproduction and explains geographical structure of a highly mobile bird.

Understanding dispersal and habitat selection behaviours is central to many problems in ecology, evolution and conservation. One factor often hypothesized to influence habitat selection by dispersers is the natal environment experienced by juveniles. Nonetheless, evidence for the effect of natal environment on dispersing, wild vertebrates remains limited. Using 18 years of nesting and mark-resight data across an entire North American geographical range of an endangered bird, the snail kite (Rostrhamus sociabilis), we tested for natal effects on breeding-site selection by dispersers and its consequences for reproductive success and population structure. Dispersing snail kites were more likely to nest in wetlands of the same habitat type (lacustrine or palustrine) as their natal wetland, independent of dispersal distance, but this preference declined with age and if individuals were born during droughts. Importantly, dispersing kites that bred in natal-like habitats had lower nest success and productivity than kites that did not. These behaviours help explain recently described population connectivity and spatial structure across their geographical range and reveal that assortative breeding is occurring, where birds are more likely to breed with individuals born in the same wetland type as their natal habitat. Natal environments can thus have long-term and large-scale effects on populations in nature, even in highly mobile animals. © 2015 The Author(s).

Nutritional status and nutritional support before and after pancreatectomy for pancreatic cancer and chronic pancreatitis.

2012-12-01

Cachexia, malnutrition, significant weight loss, and reduction in food intake due to anorexia represent the most important pathophysiological consequences of pancreatic cancer. Pathophysiological consequences result also from pancreatectomy, the type and severity of which differ significantly and depend on the type of the operation performed. Nutritional intervention, either parenteral or enteral, needs to be seen as a method of support in pancreatic cancer patients aiming at the maintenance of the nutritional and functional status and the prevention or attenuation of cachexia. Oral nutrition could reduce complications while restoring quality of life. Enteral nutrition in the post-operative period could also reduce infective complications. The evidence for immune-enhanced feed in patients undergoing pancreaticoduodenectomy for pancreatic cancer is supported by the available clinical data. Nutritional support during the post-operative period on a cyclical basis is preferred because it is associated with low incidence of gastric stasis. Postoperative total parenteral nutrition is indicated only to those patients who are unable to be fed orally or enterally. Thus nutritional deficiency is a relatively widesoread and constant finding suggesting that we must optimise the nutritional status both before and after surgery.

The incidence of epilepsy in Ethiopia is high compared with industrialised countries, but in most cases the cause of epilepsy is unknown. Childhood malnutrition remains widespread. We performed a case-control study to determine whether epilepsy is associated with poverty and markers of early under-nutrition. Patients with epilepsy (n=112), aged 18-45years, were recruited from epilepsy clinics in and around two towns in Ethiopia. Controls with a similar age and gender distribution (n=149) were recruited from patients and relatives attending general outpatient clinics. We administered a questionnaire to define the medical and social history of cases and controls, and then performed a series of anthropometric measurements. Unconditional logistic regression was used to estimate multivariate adjusted odds ratios. Multiple linear regression was used to estimate adjusted case-control differences for continuously distributed outcomes. Epilepsy was associated with illiteracy/low levels of education, odds ratio=3.0 (95% confidence interval: 1.7-5.6), subsistence farming, odds ratio=2.6 (1.2-5.6) and markers of poverty including poorer access to sanitation (p=0.009), greater overcrowding (p=0.008) and fewer possessions (p<0.001). Epilepsy was also associated with the father's death during childhood, odds ratio=2.2 (1.0-4.6). Body mass index was similar in cases and controls, but patients with epilepsy were shorter and lighter with reduced sitting height (p<0.001), bitrochanteric diameter (p=0.029) and hip size (p=0.003). Patients with epilepsy also had lower mid-upper arm circumference (p=0.011) and lean body mass (p=0.037). Epilepsy in Ethiopia is strongly associated with poor education and markers of poverty. Patients with epilepsy also had evidence of stunting and disproportionate skeletal growth, raising the possibility of a link between early under-nutrition and epilepsy.

Obesity and overweight: Impact on maternal and milk microbiome and their role for infant health and nutrition.

PubMed

Garcia-Mantrana, Izaskun; Collado, Maria Carmen

2016-08-01

Obesity, particularly in infants, is becoming a significant public health problem that has reached "epidemic" status worldwide. Obese children have an increased risk of developing obesity-related diseases, such as metabolic syndromes and diabetes, as well as increased risk of mortality and adverse health outcomes later in life. Experimental data show that maternal obesity has negative effects on the offspring's health in the short and long term. Increasing evidence suggests a key role for microbiota in host metabolism and energy harvest, providing novel tools for obesity prevention and management. The maternal environment, including nutrition and microbes, influences the likelihood of developing childhood diseases, which may persist and be exacerbated in adulthood. Maternal obesity and weight gain also influence microbiota composition and activity during pregnancy and lactation. They affect microbial diversity in the gut and breast milk. Such microbial changes may be transferred to the offspring during delivery and also during lactation, affecting infant microbial colonisation and immune system maturation. Thus, an adequate nutritional and microbial environment during the peri-natal period may provide a window of opportunity to reduce the risk of obesity and overweight in our infants using targeted strategies aimed at modulating the microbiota during early life. © 2016 WILEY-VCH Verlag GmbH & Co.

Geomagnetic imprinting: A unifying hypothesis of long-distance natal homing in salmon and sea turtles.

PubMed

Lohmann, Kenneth J; Putman, Nathan F; Lohmann, Catherine M F

2008-12-09

Several marine animals, including salmon and sea turtles, disperse across vast expanses of ocean before returning as adults to their natal areas to reproduce. How animals accomplish such feats of natal homing has remained an enduring mystery. Salmon are known to use chemical cues to identify their home rivers at the end of spawning migrations. Such cues, however, do not extend far enough into the ocean to guide migratory movements that begin in open-sea locations hundreds or thousands of kilometers away. Similarly, how sea turtles reach their nesting areas from distant sites is unknown. However, both salmon and sea turtles detect the magnetic field of the Earth and use it as a directional cue. In addition, sea turtles derive positional information from two magnetic elements (inclination angle and intensity) that vary predictably across the globe and endow different geographic areas with unique magnetic signatures. Here we propose that salmon and sea turtles imprint on the magnetic field of their natal areas and later use this information to direct natal homing. This novel hypothesis provides the first plausible explanation for how marine animals can navigate to natal areas from distant oceanic locations. The hypothesis appears to be compatible with present and recent rates of field change (secular variation); one implication, however, is that unusually rapid changes in the Earth's field, as occasionally occur during geomagnetic polarity reversals, may affect ecological processes by disrupting natal homing, resulting in widespread colonization events and changes in population structure.

Nutrition in pregnancy and early childhood and associations with obesity in developing countries.

PubMed

Yang, Zhenyu; Huffman, Sandra L

2013-01-01

Concerns about the increasing rates of obesity in developing countries have led many policy makers to question the impacts of maternal and early child nutrition on risk of later obesity. The purposes of the review are to summarise the studies on the associations between nutrition during pregnancy and infant feeding practices with later obesity from childhood through adulthood and to identify potential ways for preventing obesity in developing countries. As few studies were identified in developing countries, key studies in developed countries were included in the review. Poor prenatal dietary intakes of energy, protein and micronutrients were shown to be associated with increased risk of adult obesity in offspring. Female offspring seem to be more vulnerable than male offspring when their mothers receive insufficient energy during pregnancy. By influencing birthweight, optimal prenatal nutrition might reduce the risk of obesity in adults. While normal birthweights (2500-3999 g) were associated with higher body mass index (BMI) as adults, they generally were associated with higher fat-free mass and lower fat mass compared with low birthweights (<2500 g). Low birthweight was associated with higher risk of metabolic syndrome and central obesity in adults. Breastfeeding and timely introduction of complementary foods were shown to protect against obesity later in life in observational studies. High-protein intake during early childhood however was associated with higher body fat mass and obesity in adulthood. In developed countries, increased weight gain during the first 2 years of life was associated with a higher BMI in adulthood. However, recent studies in developing countries showed that higher BMI was more related to greater lean body mass than fat mass. It appears that increased length at 2 years of age was positively associated with height, weight and fat-free mass, and was only weakly associated with fat mass.

Nutrition education of adolescent competitive swimmers is under-studied although their diet and nutrition knowledge are generally poor. This study aimed to assess the impact of nutrition education on nutrition knowledge and adherence to the Mediterranean Diet (MD) and explore the effect of parental education on the swimmers' MD adherence. A pre-post measurement interventional study was carried out. A half-day nutrition education session was delivered for the swimmers and a separate session for their parents. At baseline and 6-weeks post-workshop, a short nutrition knowledge assessment of food sources of nutrients and the MD composition as well as adherence to the MD using the KIDMED Index were undertaken. The swimmers' parents also completed the KIDMED Index to evaluate the swimmers' diet. Thirty-four competitive swimmers (age: 15.2±1.5 yr, 23 males) and 22 of their parents participated in the study. There was an improvement in MD adherence with 47% having good adherence post-intervention vs 21% at baseline (p<0.01) and an increase in the KIDMED Index score (median [interquartile range]: 5.0 [4.0-7.0] vs 7.0 [7.0-9.0]; p<0.01)). There was also an increase in the swimmers' nutrition knowledge assessment score (median [IQR]: 7.0 [5.0-8.0] vs 7.0 [6.0-8.0], p<0.05)), and a trend for a lower score post-intervention in swimmers whose parents did not participate compared to those whose parents participated (6.0 [6.0-7.8] vs 7.0 [7.0-8.0], p=0.063). The intervention improved adherence to the MD and increased nutrition knowledge. The findings support parental participation in nutrition education. Copyright © 2016 Sports Medicine Australia.

2016-01-01

Objective Children in foster care are at greater risk for poor health, physical, cognitive, behavioral, and developmental outcomes than are children in the general population. Considerable research links early nutrition to later cognitive and behavioral outcomes. The aim of this narrative review is to examine the prevalence of poor nutrition and its relation to subsequent health and development in foster children. Method Relevant studies for inclusion were identified from numerous sources (e.g., PubMed, Google Scholar, and reference sections). Inclusion criteria were studies published between 1990 and 2016 of (i) the nutritional status of children in foster care or (ii) the nutritional status of children exposed to early adversity (e.g., low-income and internationally adopted children) or (iii) the developmental effects of poor nutrition and micronutrient deficiencies. Results Two key findings that have adverse implications for cognitive development emerged: (i) the prevalence of anemia and iron-deficiency anemia is higher among foster children than among the general population of children in the U.S., and (ii) the developmental demands of catch-up growth post-placement may lead to micronutrient deficiencies even after children have begun sufficient dietary intake of these nutrients. Moreover, there is a paucity of recent studies on the nutritional status of children in foster care, despite the multiple factors that may place them at risk for malnutrition. Conclusion Attention to nutritional status among care providers and medical professionals may remove one of the possible negative influences on foster children's development and in turn significantly alter their trajectories and place them on a more positive path early in life. Recommendations for further research, policy, and practice are discussed. PMID:28626279

Attention to nutritional status among care providers and medical professionals may remove one of the possible negative influences on foster children's development and in turn significantly alter their trajectories and place them on a more positive path early in life. Recommendations for further research, policy, and practice are discussed.

Combined bilateral mastectomy and reconstruction is a common major surgical procedure in women with breast cancer and in those with a family history of breast cancer. As this large surgical procedure induces muscle protein loss, a preserved anabolic response to nutrition is warranted for optimal recovery. It is unclear whether the presence of early stage cancer negatively affects the protein metabolic response to major surgery as this would mandate perioperative nutritional support. In nine women with early stage (Stage II) breast malignancy and nine healthy women with a genetic predisposition to breast cancer undergoing the same large surgical procedure, we examined whether surgery influences the catabolic response to overnight fasting and the anabolic response to nutrition differently. Prior to and within 24 h after combined bilateral mastectomy and reconstruction surgery, whole body protein synthesis and breakdown rates were assessed after overnight fasting and after meal intake by stable isotope methodology to enable the calculation of net protein catabolism in the post-absorptive state and net protein anabolic response to a meal. Major surgery resulted in an up-regulation of post-absorptive protein synthesis and breakdown rates (P < 0.001) and lower net protein catabolism (P < 0.05) and was associated with insulin resistance and increased systemic inflammation (P < 0.01). Net anabolic response to the meal was reduced after surgery (P < 0.05) but higher in cancer (P < 0.05) indicative of a more preserved meal efficiency. The significant relationship between net protein anabolism and the amount of amino acids available in the circulation (R 2  = 0.85, P < 0.001) was independent of the presence of non-cachectic early stage breast cancer or surgery. The presence of early stage breast cancer does not enhance the normal catabolic response to major surgery or further attenuates the anabolic response to meal intake within 24 h after

Highly migratory organisms present major challenges to conservation efforts. This is especially true for exploited anadromous fish species, which exhibit long-range dispersals from natal sites, complex population structures, and extensive mixing of distinct populations during exploitation. By tracing the migratory histories of individual Chinook salmon caught in fisheries using strontium isotopes, we determined the relative production of natal habitats at fine spatial scales and different life histories. Although strontium isotopes have been widely used in provenance research, we present a new robust framework to simultaneously assess natal sources and migrations of individuals within fishery harvests through time. Our results pave the way for investigating how fine-scale habitat production and life histories of salmon respond to perturbations—providing crucial insights for conservation.

Eleven female participants from a NCAA Division I volleyball team were evaluated for adequate energy and macronutrient intake during two off-seasons. Total energy and macronutrient intake were assessed by food records and results were compared against estimated needs using the Nelson equation. Dietary intervention was employed regarding the individual dietary needs of each athlete as well as a pre- and post-sports nutrition knowledge survey. Post dietary intervention, total energy, and macronutrient intake improved, as well as a significant improvement in sports nutrition knowledge (p < 0.001). Nutrition education is useful in improving dietary intake and nutrition knowledge of female athletes. PMID:22822449

Early life stress has enduring effects on behavior and physiology. However, the effects on hormones and stress physiology remain poorly understood. In the present study, parents of zebra finches of both sexes were exposed to an increased foraging paradigm from 3 to 33days post hatching. Plasma and brains were collected from chicks at 3 developmental time points: post hatching days 25, 60 and adulthood. Plasma was assayed for testosterone (T), estradiol (E2), and corticosterone (CORT). The paraventricular nucleus of the hypothalamus was assessed for corticotrophin releasing factor (CRH) and glucocorticoid receptor (GR) expression. As expected, body mass was lower in nutritionally stressed animals compared to controls at multiple ages. Nutritionally stressed animals overall had higher levels of CORT than did control and this was particularly apparent in females at post hatching day 25. Nutritionally stressed animals also had a higher number of cells expressing CRH and GR in the paraventricular nucleus of the hypothalamus than did controls. There was an interaction, such that both measures were higher in control animals at PHD 25, but higher in NS animals by adulthood. Females, regardless of treatment, had higher circulating CORT and a higher number of cells expressing CRH than did males. Nutritionally stressed animals also had higher levels of T than did control animals, and this difference was greatest for males at post hatching day 60. There were no effects of nutritional stress on E2. These findings suggest that nutritional stress during development has long-lasting effects on testosterone and stress physiology.

Managing malnutrition before liver transplantation (LTx) while on the waiting list and, excessive weight gain/metabolic disturbances in post-surgery are still a challenge in LTx care. The aim of this review is to support an interdisciplinary nutrition approach of these patients. Cirrhotic patients are frequently malnourished before LTx and this is associated with a poor prognosis. Although the relation between nutritional status versus survival, successful operation and recovery after LTx is well established, prevalence of malnutrition before the operation is still very high. Emerging research has also demonstrated that sarcopenia pre and post-transplant is highly prevalent, despite the weight gain in the postoperative period. The diagnosis of the nutritional status is the first step to address the adequate nutritional therapy. Nutritional recommendations and therapy to manage the nutritional status of LTx patients are discussed in this review, regarding counseling on adequate diets and findings of the latest research on using certain immunonutrients in these patients (branched chain amino-acids, pre and probiotics). Nutrition associated complications observed after transplantation is also described. They are commonly related to the adverse effects of immunosuppressive drugs, leading to hyperkalemia, hyperglycemia and weight gain. Excessive weight gain and post-transplant metabolic disorders have long been described in post-LTx and should be addressed in order to reduce associated morbidity and mortality.

Nesting fidelity and molecular evidence for natal homing in the freshwater turtle, Graptemys kohnii

2005-01-01

Numerous studies of sea turtle nesting ecology have revealed that females exhibit natal homing, whereby they imprint on the nesting area from which they hatch and subsequently return there to nest as adults. Because freshwater turtles comprise the majority of reptiles known to display environmental sex determination (ESD), the study of natal homing in this group may shed light on recent evolutionary models of sex allocation that are predicated on natal homing in reptiles with ESD. We examined natal homing in Graptemys kohnii, a freshwater turtle with ESD, using mitochondrial sequencing, microsatellite genotyping and mark and recapture of 290 nesting females. Females showed high fidelity to nesting areas, even after being transplanted several kilometres away. A Mantel test revealed significant genetic isolation by distance with respect to nesting locations (r=0.147; p<0.05), suggesting that related females nest in close proximity to one another. The patterns of fidelity and genotype distributions are consistent with homing at a scale that may affect population sex ratios. PMID:16006324

To evaluate pain incidence and intensity in patients undergoing septorhinoplasty, and to assess analgesic treatment effectiveness, in the first 7 days after surgery. Prospective outcomes analysis using visual analogue scale assessment of pain intensity in the first 7 post-operative days. Fifty-seven patients were enrolled in the study, 29 women and 28 men, aged 18 to 51 years. All were treated for post-traumatic deformity of the external nose and/or nasal septum, with either septorhinoplasty or septoplasty. In the first 3 days after septorhinoplasty, patients' mean visual analogue scale pain score exceeded the range denoting 'analgesic success', and showed considerable exacerbation in the evening. Patients' pain decreased to a mean score of 15.4 one hour after administration of a nonsteroidal anti-inflammatory drug (metamizole). Analgesia is recommended for all patients in the first 3 days after septorhinoplasty, especially in the early evening.

Mice Deficient in NF-κB p50 and p52 or RANK Have Defective Growth Plate Formation and Post-natal Dwarfism.

NF-κBp50/p52 double knockout (dKO) and RANK KO mice have no osteoclasts and develop severe osteopetrosis associated with dwarfism. In contrast, Op/Op mice, which form few osteoclasts, and Src KO mice, which have osteoclasts with defective resorptive function, are osteopetrotic, but they are not dwarfed. Here, we compared the morphologic features of long bones from p50/p52 dKO, RANK KO, Op/Op and Src KO mice to attempt to explain the differences in their long bone lengths. We found that growth plates in p50/p52 dKO and RANK KO mice are significantly thicker than those in WT mice due to a 2-3-fold increase in the hypertrophic chondrocyte zone associated with normal a proliferative chondrocyte zone. This growth plate abnormality disappears when animals become older, but their dwarfism persists. Op/Op or Src KO mice have relatively normal growth plate morphology. In-situ hybridization study of long bones from p50/p52 dKO mice showed marked thickening of the growth plate region containing type 10 collagen-expressing chondrocytes. Treatment of micro-mass chondrocyte cultures with RANKL did not affect expression levels of type 2 collagen and Sox9, markers for proliferative chondrocytes, but RANKL reduced the number of type 10 collagen-expressing hypertrophic chondrocytes. Thus, RANK/NF-κB signaling plays a regulatory role in post-natal endochondral ossification that maintains hypertrophic conversion and prevents dwarfism in normal mice.

Nutrition in Patients with Gastric Cancer: An Update.

PubMed

2016-05-01

Nutritional management of patients with gastric cancer (GC) represents a challenge. This review provides an overview of the present evidence on nutritional support in patients with GC undergoing surgery as well as in those with advanced disease. For patients undergoing surgery, the preoperative nutritional condition directly affects postoperative prognosis, overall survival and disease-specific survival. Perioperative nutritional support enriched with immune-stimulating nutrients reduces overall complications and hospital stay but not mortality after major elective gastrointestinal surgery. Early enteral nutrition after surgery improves early and long-term postoperative nutritional status and reduces the length of hospitalization as well. Vitamin B12 and iron deficiency are common metabolic sequelae after gastrectomy and warrant appropriate replacement. In malnourished patients with advanced GC, short-term home complementary parenteral nutrition improves the quality of life, nutritional status and functional status. Total home parenteral nutrition represents the only modality of caloric intake for patients with advanced GC who are unable to take oral or enteral nutrition. Early evaluations of nutritional status and nutritional support represent key aspects in the management of GC patients with both operable and advanced disease.

Update on the nutrition situation.

PubMed

Mason, J; Garcia, M

1995-01-01

The Update on the Nutrition Situation, 1994 was published in early 1995 by the United Nations Subcommittee on Nutrition. Thus, data available at the country level about estimates of the nutritional situation now provide trends of prevalences of underweight children in 35 countries for the 1990s. In Sub-Saharan Africa recent deterioration has occurred as a result of the general worsening of nutrition in Africa. However, in the Near East, North Africa, and South America the generally improving trends of the 1980s seem to be continuing with the likelihood of reaching the prevalences of the developed countries by the year 2000. A surveillance system in Bangladesh indicates improvement from 1990 to 1993; however, India data for 1991/92 indicate deterioration in 3 states and no significant change in 4, possibly connected the economic slowdown in the early 1990s. In many countries of southeast Asia, China, Middle America and the Caribbean, South America, the Near East and North Africa the improvement of rates could result in halving the prevalences of underweight children. The gross domestic product (GDP) is an important indicator of nutritional performance. During 1985-92 in Sub-Saharan Africa GDP declined by 0.8% and consequently the nutritional situation also deteriorated. In other areas of the world the GDP growth rates improved after 1990 and the underweight trends in the early 1990s were generally similar to those of the late 1980s. The nutritional improvement outside Sub-Saharan Africa and possibly India continued in the early 1990s. Rapid economic growth was associated with improving nutrition in Thailand and Vietnam in the 1980s and also to a smaller extent for Indonesia and China. Faster than average improvement is plausible for Jamaica, Sri Lanka, and Zimbabwe. Deteriorating cases are Ethiopia, Madagascar, and Rwanda. Economic growth, health, education, and community-based nutrition programs all contribute to improving nutrition.

This study investigated the effects of a sport nutrition education intervention (SNEI) on dietary intake, knowledge, body composition, and performance in NCAA Division I baseball players. Resistance trained NCAA Division I baseball players (82.4 ± 8.2 kg; 1.83 ± 0.06 m; 13.7 ± 5 % body fat) participated in the study during 12 weeks of off-season training. Fifteen players volunteered for SNEI while 15 players matched for position served as controls (C) for body composition and performance. The nutrition intervention group (NI) received a 90 min SNEI encompassing energy intake (Kcal), carbohydrate (CHO), protein (PRO), fat, food sources, and hydration. Sport nutrition knowledge questionnaires were administered to NI pre and post. Nutritional status was determined by three-day dietary logs administered to NI pre and post. Body composition and performance (5-10-5 shuttle test, vertical jump, broad jump, 1 RM squat) were measured pre and post for C and NI. Knowledge increased in NI. Pro and fat, but not CHO intake increased in NI. FM decreased pre to post in NI (11.5 ± 4.8 vs. 10.5 ± 5.4 kg) but not C (11.3 ± 4.7 vs. 11.9 ± 4.5 kg). FFM increased pre to post with no differences between groups. The 5-10-5 shuttle times decreased significantly more in NI (4.58 ± 0.15 vs. 4.43 ± 0.13 sec) compared to C (4.56 ± 0.18 vs. 4.50 ± 0.16 sec). Jump and squat performance increased pre to post with no differences between groups. Our findings indicate that an off season SNEI is effective at improving sport nutrition knowledge and some, but not all, nutrient intakes and performance measures in Division I baseball players.

Eruption of tooth at about 6 months of age is a significant stage in child’s life and is an emotional event for parents. However, a tooth present in the oral cavity of newborn can lead to a lot of delusions. Natal and neonatal teeth are of utmost importance not only for a dentist but also for a paediatrician due to parent’s anxiety, folklore superstitions and numerous associated complications with it. This paper reports a rare case, wherein a natal tooth has led to the development of a reactive fibrous hyperplasia in an 8-week-old infant. PMID:26023656

Nutritional support is a cornerstone in acute pancreatitis (AP) treatment, which is a catabolic state that can result in patient's nutritional depletion. First step in the management of AP is to asses its severity. Despite mild AP cases usually do not require nutritional support severe cases benefit from its early initiation. Total enteral nutrition (TEN) decreases the frequency of complications and is the preferred nutrition modality in AP. Availability of nutrition specialists is often limited and usually the primary care physician decides when and how to start nutritional support in AP. To perform a systematic review about nutritional support in AP and create a TEN guide to aid the non nutrition specialist involved in the treatment of AP patients. The search for eligible studies was carried out using the Pub Med and the National Library of Medicine electronic data bases. Controlled clinical trials, treatment guidelines and systematic review articles were selected. It is recommended to initiate nutritional support in AP cases that will be without oral intake longer than a week and TEN is the election modality. We created a TEN guide explaining how to choose and initiate TEN in AP. Early TEN improves AP prognosis and is the nutritional modality of choice in every AP patients that will remain without oral intake longer than a week.

Nutrition Therapy in Sepsis.

PubMed

Wischmeyer, Paul E

2018-01-01

Sepsis is characterized by early massive catabolism, lean body mass (LBM) loss, and escalating hypermetabolism persisting for months to years. Early enteral nutrition should attempt to correct micronutrient/vitamin deficiencies, deliver adequate protein and moderated nonprotein calories, as well-nourished patients can generate reasonable endogenous energy. After resuscitation, increasing protein/calories are needed to attenuate LBM loss and promote recovery. Malnutrition screening is essential, and parenteral nutrition can be safely added when enteral nutrition is failing based on preillness malnutrition. Following discharge from intensive care unit, significantly increased protein/calorie delivery is required for months to years to facilitate functional and LBM recovery.

The purpose of this study was to examine whether the combination of high-intensity interval training (HIIT) and post-exercise protein supplementation would improve cardiovascular outcomes in individuals with T2D. In a double-blind controlled trial, fifty-three adults with T2D (free of CVD and not on exogenous insulin) were randomized to 12weeks of cardio and resistance-based HIIT (4-10×1min at 90% maximal heart rate) with post-exercise milk, milk-protein, or placebo supplementation, thrice weekly. Before and after, carotid and femoral artery intima media thickness (IMT) and femoral flow profiles were assessed using high-resolution ultrasound. Central and peripheral arterial stiffness were assessed by pulse wave velocity (PWV), and resting and maximal heart rate rates were measured. After 12weeks of HIIT femoral IMT (Pre: 0.84±0.21mm vs. Post: 0.81±0.16mm, p=0.03), carotid-femoral PWV (Pre: 10.1±3.2m/s vs. Post: 8.6±1.8m/s, p<0.01) and resting heart rate (Pre: 70.4±10.8bpm vs. Post: 67.8±8.6 bpm, p=0.01) were all significantly lower. There were no differences between nutrition groups (all significant main effects of time) for all outcomes. HIIT reduces femoral IMT, arterial stiffness and resting heart rate in individuals with T2D. The addition of post-exercise milk or protein to HIIT did not have additive effects for improving cardiovascular outcomes in the present study. Taken together, HIIT alone may be an effective means to reduce the burden of cardiovascular complications in T2D. Copyright © 2017 Elsevier Inc. All rights reserved.

Maternal nutritional status is a determinant of child health. This paper studies the association between a mother's body mass index (BMI) and her infant's nutritional status over a one year time frame after the 1998 flood crisis in Bangladesh. The paper uses secondary analysis of data collected from 757 households in seven rural areas of Bangladesh affected by the 1998 flood using multiple-stage probability sampling techniques (n = 143). Logistic regression models were employed to investigate the predictive impact of maternal BMI on infant's nutritional status after controlling for a range of child and maternal factors. An underweight mother was a significant factor with regard to the risk of infants suffering stunting (odds ratio (OR) = 4.45, 95 per cent confidence interval (CI) = 1.04-18.94) and being underweight (OR = 3.51, 95 per cent CI = 1.02-12.05) a year later, but not wasting (OR = 2.09, 95 per cent CI = 0.51-8.67). The findings suggest that there is a post-emergency link between maternal and infant nutritional health. © 2011 The Author(s). Disasters © Overseas Development Institute, 2011.

Early enteral feeding compared with parenteral nutrition after oesophageal or oesophagogastric resection and reconstruction.

After resective and reconstructive surgery in the gastrointestinal tract, oral feeding is traditionally avoided in order to minimize strain to the anastomoses and to reduce the inherent risks of the postoperatively impaired gastrointestinal motility. However, studies have given evidence that the small bowel recovers its ability to absorb nutrients almost immediately following surgery, even in the absence of peristalsis, and that early enteral feeding would preserve both the integrity of gut mucosa and its immunological function. The aim of this study was to investigate the impact of early enteral feeding on the postoperative course following oesophagectomy or oesophagogastrectomy, and reconstruction. Between May 1999 and November 2002, forty-four consecutive patients (thirty-eight males and six females; mean age 62, range 30-82) with oesophageal carcinoma (stages I-III), who had undergone radical resection and reconstruction, entered this study (early enteral feeding group; EEF). A historical group of forty-four patients (thirty-seven males and seven females; mean age 64, range 41-79; stages I-III) resected between January 1997 and March 1999 served as control (parenteral feeding group; PF). The duration of both postoperative stay in the Intensive Care Unit (ICU) and the total hospital stay, perioperative complications and the overall mortality were compared. Early enteral feeding was administered over the jejunal line of a Dobhoff tube. It started 6 h postoperatively at a rate of 10 ml/h for 6 h with stepwise increase until total enteral nutrition was achieved on day 6. In the controls oral enteral feeding was begun on day 7. If compared to the PF group, EEF patients recovered faster considering the duration of both stay in the ICU and in the hospital. There was a significant difference in the interval until the first bowel movements. No difference in overall 30 d mortality was identified. A poor nutritional status was a significant prognostic factor for an

The aim of this study was to investigate the association between maternal iron/zinc serum levels and their nutritional intake in early pregnancy with gestational diabetes. The maternal serum zinc/iron levels were measured in 1,033 healthy singleton pregnant women aged 20-35 between 14 and 20 weeks of gestation, within two groups: namely, normal and gestational diabetes, and participants were followed up to 24-28 weeks of gestation. Food frequency questionnaire was used to assess nutritional intakes of iron/zinc. The main outcome was gestational diabetes screened with the 50-g glucose challenge test and diagnosed with oral glucose tolerance test at 24-28 weeks of gestation. Gestational diabetes occurred in 72 (6.96 %) of 1,033 women in study. There was a statistical relationship between early pregnancy maternal serum iron and gestational diabetes, mean (SD), 143.8 (48.7) vs. 112.5 (83.5) μg/dl, P value of <0.0001. There was no statistical significant difference in zinc levels and iron/zinc nutritional intake between groups. The results remained unchanged after using regression model for adjustment of potential risk factors with an adjusted OR of 1.006 (95 % CI 1.002 to 1.009; P = 0.001) for early pregnancy maternal serum iron to cause gestational diabetes. The receiver-operator characteristic curve identified that a maternal serum iron above 100 μg/dl in early pregnancy is the optimum cutoff value for predicting gestational diabetes, which showed a sensitivity and specificity of 80.6 and 50.7 %, respectively. In conclusion, high maternal serum iron in early pregnancy could increase the risk of gestational diabetes. Also, it could be used as a sensitive and specific predictor for gestational diabetes.

Infection is a leading cause of death after liver transplantation (LT). Therefore, prevention of infection is crucial for improving outcomes after LT. We examined the impact of early enteral nutrition with an immunomodulating diet (IMD) enriched with hydrolyzed whey peptide (HWP) formulation on infection after living donor LT (LDLT), focusing on sarcopenia. This study enrolled 279 consecutive patients who underwent primary LDLT at our institute between January 2008 and April 2015. Early enteral nutrition with the IMD enriched with HWP formulation and a conventional elemental diet were started within the first 24 h after surgery for 164 (IMD-HWP) and 115 (conventional) patients. Sequential changes in nutritional parameters, and the incidences of acute cellular rejection (ACR) and bacteremia were compared between the IMD-HWP and control groups. The comparison was made between those members of each group that did or did not exhibit sarcopenia. Risk factors for post-transplant bacteremia were also assessed. Postoperative nutritional parameters and the incidence of ACR were comparable between the groups, except for the prealbumin level. The incidence of bacteremia was significantly lower in the IMD-HWP group, and among patients without sarcopenia in the IMD-HWP group compared with the conventional group (24.4 vs. 41.7%; P = 0.002 and 20.8 vs. 39.0%; P = 0.040, respectively). Independent risk factor for bacteremia comprised bleeding ≥10,000 mL (P = 0.025). In contrast, enteral nutrition without HWP formulation was not significantly associated with bacteremia. However, enteral nutrition without HWP formulation (P = 0.080), MELD scores (P = 0.097), and ABO incompatibility (P = 0.088) showed a trend toward increased incidence of bacteremia, although they did not reach statistical significance in the multivariate analysis. Postoperative immunonutrition with an IMD enriched with HWP formulation was closely involved with post-transplant bacteremia.

Social marketing is a promising planning approach for influencing voluntary lifestyle behaviours, but its application to nutrition and physical activity interventions in the early care and education setting remains unknown. PubMed, ISI Web of Science, PsycInfo and the Cumulative Index of Nursing and Allied Health were systematically searched to identify interventions targeting nutrition and/or physical activity behaviours of children enrolled in early care centres between 1994 and 2016. Content analysis methods were used to capture information reflecting eight social marketing benchmark criteria. The review included 135 articles representing 77 interventions. Two interventions incorporated all eight benchmark criteria, but the majority included fewer than four. Each intervention included behaviour and methods mix criteria, and more than half identified audience segments. Only one-third of interventions incorporated customer orientation, theory, exchange and insight. Only six interventions addressed competing behaviours. We did not find statistical significance for the effectiveness of interventions on child-level diet, physical activity or anthropometric outcomes based on the number of benchmark criteria used. This review highlights opportunities to apply social marketing to obesity prevention interventions in early care centres. Social marketing could be an important strategy for early childhood obesity prevention efforts, and future research investigations into its effects are warranted. © 2017 World Obesity Federation.

Natal teeth are those present in the oral cavity at the child's birth. These teeth can cause ulcers on the ventral surface of the tongue, lip, and the mother's breast characterizing the Riga-Fede Disease. The treatment depends on the tooth's mobility and the risk of aspiration or swallowing; whether it is supernumerary or regular primary teeth; whether it is causing interference in breastfeeding; breast and oral soft tissue injuries; and the general state of child's health. A 1-month-old female infant was diagnosed with two natal teeth and an ulcerated lesion on the ventral surface of the tongue, leading to the clinical diagnosis of Riga-Fede Disease. The treatment performed consisted of the maintenance of the natal tooth that showed no increased mobility, adding a small increment of glass ionomer cement to its incisal edge, and orientation for hygiene with saline solution. Due to the increased mobility of the other natal tooth, surgical removal was performed. There was regular monitoring of the patient and complete wound healing was observed after 15 days. The proposed treatment was successful and the patient is still in follow-up without recurrence of the lesion after one year.

Studying how the healthy human brain develops is important to understand early pathological mechanisms and to assess the influence of fetal or perinatal events on later life. Brain development relies on complex and intermingled mechanisms especially during gestation and first post-natal months, with intense interactions between genetic, epigenetic and environmental factors. Although the baby's brain is organized early on, it is not a miniature adult brain: regional brain changes are asynchronous and protracted, i.e. sensory-motor regions develop early and quickly, whereas associative regions develop later and slowly over decades. Concurrently, the infant/child gradually achieves new performances, but how brain maturation relates to changes in behavior is poorly understood, requiring non-invasive in vivo imaging studies such as magnetic resonance imaging (MRI). Two main processes of early white matter development are reviewed: (1) establishment of connections between brain regions within functional networks, leading to adult-like organization during the last trimester of gestation, (2) maturation (myelination) of these connections during infancy to provide efficient transfers of information. Current knowledge from post-mortem descriptions and in vivo MRI studies is summed up, focusing on T1- and T2-weighted imaging, diffusion tensor imaging, and quantitative mapping of T1/T2 relaxation times, myelin water fraction and magnetization transfer ratio.

Hinsull, S. M.; Bellamy, D.; Head, E. L.

1981-12-01

The effect of continuous positive and negative ionization on the growth of rats during the pre and post natal period, up to 10 weeks of age was investigated. It was found that continuous exposure to 1.0×104 pos. ions/ml had no detrimental effect on the animals at any stage of their development. In contrast, exposure to 1.0×104 neg. ions/ml, during gestation and the early post natal period, resulted in some adverse effects on growth and development. However, when exposure to this level of negative ions began at the time of weaning, no adverse effects were observed.

Early-Life Nutritional Programming of Type 2 Diabetes: Experimental and Quasi-Experimental Evidence.

Vaiserman, Alexander M

2017-03-05

Consistent evidence from both experimental and human studies suggest that inadequate nutrition in early life can contribute to risk of developing metabolic disorders including type 2 diabetes (T2D) in adult life. In human populations, most findings supporting a causative relationship between early-life malnutrition and subsequent risk of T2D were obtained from quasi-experimental studies ('natural experiments'). Prenatal and/or early postnatal exposures to famine were demonstrated to be associated with higher risk of T2D in many cohorts around the world. Recent studies have highlighted the importance of epigenetic regulation of gene expression as a possible major contributor to the link between the early-life famine exposure and T2D in adulthood. Findings from these studies suggest that prenatal exposure to the famine may result in induction of persistent epigenetic changes that have adaptive significance in postnatal development but can predispose to metabolic disorders including T2D at the late stages of life. In this review, quasi-experimental data on the developmental programming of T2D are summarized and recent research findings on changes in DNA methylation that mediate these effects are discussed.

Laparoscopic proximal gastrectomy (LPG) has recently been applied for early gastric cancer (EGC) in the upper stomach as a minimally invasive and function-preserving surgery. This study aimed to clarify the feasibility and nutritional benefits of LPG over laparoscopic total gastrectomy (LTG). This was a retrospective study of 77 patients with clinical stage I gastric cancer in the upper stomach. Of these patients, 25 underwent LPG, while 52 underwent LTG. Surgical outcomes and postoperative nutritional status such as changes in body weight and blood chemistries were compared between LPG and LTG. Intraoperative blood loss and C-reactive protein levels at 3 and 7 days after surgery were significantly lower in LPG than in LTG (p = 0.018, 0.036, and 0.042, respectively). No significant differences were observed in postoperative early or late complication rates between LPG and LTG. The incidence of Los Angeles Grade B or more severe reflux esophagitis after LPG was 9.1 %, which was similar to that after LTG (9.3 %). Postoperative changes in body weight at 6 months and 1 and 2 years after surgery were consistently less in LPG than in LTG (p = 0.001, 0.022, and 0.001, respectively). Moreover, postoperative levels of hemoglobin and serum albumin and total lymphocyte count were also higher in LPG than in LTG. LPG may be a better choice for EGC in the upper stomach than LTG because it has distinct advantages in terms of surgical invasiveness and postoperative nutritional status.

Current understanding of biologic processes indicates that women's nutritional status before and during early pregnancy may play an important role in determining early developmental processes and ensuring successful pregnancy outcomes. We conducted a systematic review of the evidence for the impact of maternal nutrition before and during early pregnancy (<12 weeks gestation) on maternal, neonatal and child health outcomes and included 45 articles (nine intervention trials and 32 observational studies) that were identified through PubMed and EMBASE database searches and examining review articles. Intervention trials and observational studies show that periconceptional (<12 weeks gestation) folic acid supplementation significantly reduced the risk of neural tube defects. Observational studies suggest that preconceptional and periconceptional intake of vitamin and mineral supplements is associated with a reduced risk of delivering offspring who are low birthweight and/or small-for-gestational age (SGA) and preterm deliveries (PTD). Some studies report that indicators of maternal prepregnancy size, low stature, underweight and overweight are associated with increased risks of PTD and SGA. The available data indicate the importance of women's nutrition prior to and during the first trimester of pregnancy, but there is a need for well-designed prospective studies and controlled trials in developing country settings that examine relationships with low birthweight, SGA, PTD, stillbirth and maternal and neonatal mortality. The knowledge gaps that need to be addressed include the evaluation of periconceptional interventions such as food supplements, multivitamin-mineral supplements and/or specific micronutrients (iron, zinc, iodine, vitamin B-6 and B-12) as well as the relationship between measures of prepregnancy body size and composition and maternal, neonatal and child health outcomes. © 2012 Blackwell Publishing Ltd.

Early-life microbial exposure is of particular importance to growth, immune system development and long-lasting health. Hence, early microbiota composition is a promising predictive biomarker for health and disease but still remains poorly characterized in regards to susceptibility to diarrhoea. In the present study, we aimed to assess if gut bacterial community diversity and composition during the suckling period were associated with differences in susceptibility of pigs to post-weaning diarrhoea. Twenty piglets from 5 sows (4 piglets / litter) were weaned in poor housing conditions to challenge their susceptibility to post-weaning diarrhoea. Two weeks after weaning, 13 pigs exhibited liquid faeces during 2 or 3 days and were defined as diarrhoeic (D) pigs. The other 7 pigs did not have diarrhea during the whole post-weaning experimental periodand were defined as healthy (H) pigs. Using a molecular characterisation of fecal microbiota with CE-SSCP fingerprint, Next Generation Sequencing and qPCR, we show that D and H pigs were mainly discriminated as early as postnatal day (PND) 7, i.e. 4 weeks before post-weaning diarrhoea occurence. At PND 7 H pigs displayed a lower evenness and a higher abundance of Prevotellaceae, Lachnospiraceae, Ruminocacaceae and Lactobacillaceae compared to D pigs. The sPLS regression method indicates that these bacterial families were strongly correlated to a higher Bacteroidetes abundance observed in PND 30 H pigs one week before diarrhoea. These results emphasize the potential of early microbiota diversity and composition as being an indicator of susceptibility to post-weaning diarrhoea. Furthermore, they support the health promoting strategies of pig herds through gut microbiota engineering. PMID:28072880

In this study, the nutritional and recovery habits of tennis players pre-, during, and post-match-play were investigated. Seventy tennis players completed a bespoke nutrition and recovery habits questionnaire, with questions related to the following areas: match preparation, intra-match nutritional habits, situation dependent variables, and post-match nutrition and recovery. On match day-1, the consumption of balanced meals consisting of carbohydrate (CHO), fat and protein, with some micronutrient considerations were reported by 51% of players. On match-days, CHOs were prioritised prior to match-play with CHO dominant meals consumed by the majority of players. During matches, all players adopted a nutritional strategy, with water (94%), banana(s) (86%) and sports drinks (50%) commonly used. Carbohydrate rich nutritional aids, including sports drinks (80%) and energy gels (26%) were utilised more readily during long matches (>2 h). The day after match-play, 39% of players reported the consumption of "nothing specific". Multiple post-match recovery strategies were adopted by 80% of players, with foam rolling (77%), ice baths (40%), protein shake intake (37%) and hot baths (26%) most used. Findings indicate highly variable eating and recovery habits in tennis players pre-, during and post-match-play, with scope for improved practices.

Objective: To evaluate the effects of early enteral nutrition on the gastrointestinal motility and intestinal mucosal barrier of patients with burn-induced invasive fungal infection. Methods: A total of 120 patients with burn-induced invasive fungal infection were randomly divided into an early enteral nutrition (EN) group and a parenteral nutrition (PN) group (n=60). The patients were given nutritional support intervention for 14 days, and the expression levels of serum transferrin, albumin, total protein, endotoxin, D-lactic acid and inflammatory cytokines were detected on the 1st, 7th and 14th days respectively. Results: As the treatment progressed, the levels of serum transferrin, albumin and total protein of the EN group were significantly higher than those of the PN group (P<0.05), while the levels of serum endotoxin and D-lactic acid of the form group were significantly lower (P<0.05). After treatment, the expression levels of IL-6 and TNF-α were decreased in the EN group, which were significantly different from those of the PN group (P<0.05). During treatment, the incidence rates of complications such as abdominal distension, diarrhea, sepsis, nausea, vomiting and gastric retention were similar. The mean healing time of wound surface was 9.34±0.78 days in the EN group and 12.46±2.19 days in the PN group, i.e. such time of the former was significantly shorter than that of the latter (P<0.05). Conclusion: Treating patients having burn-induced invasive fungal infection by early enteral nutrition support with arginine can safely alleviate malnutrition and stress reaction, strengthen cellular immune function and promote wound healing, thereby facilitating the recovery of gastrointestinal motility and the function of intestinal mucosal barrier.

A suboptimal early-life environment, due to poor nutrition or stress during pregnancy, can influence lifelong phenotypes in the progeny. Epigenetic factors are thought to be key mediators of these effects. We show that protein restriction in mice from conception until weaning induces a linear correlation between growth restriction and DNA methylation at ribosomal DNA (rDNA). This epigenetic response remains into adulthood and is restricted to rDNA copies associated with a specific genetic variant within the promoter. Related effects are also found in models of maternal high-fat or obesogenic diets. Our work identifies environmentally induced epigenetic dynamics that are dependent on underlying genetic variation and establishes rDNA as a genomic target of nutritional insults.

Studies have identified prenatal flavour exposure as a determinant of taste preferences in infants; however, these studies have focused on relatively small samples and limited flavours. As many parents struggle with getting children to accept a variety of nutritious foods, a study of the factors influencing food acceptance is warranted. The objective of this study was to determine whether exposure to a wider variety of fruit and vegetables and overall higher diet quality in utero results in acceptance of a greater variety of these foods and better diet quality for offspring during childhood. This study is a secondary data analysis of pregnant women (n = 52) and their resulting offspring recruited for the Women and Their Children's Health study in NSW, Australia. Dietary intake of mothers and children was measured using food frequency questionnaires. Diet quality and vegetable and fruit variety were calculated using the Australian Recommended Food Score and the Australian Child and Adolescent Recommended Food Score. Associations between maternal and child diet quality and variety were assessed using Pearson's correlations and the total effect of in utero maternal pregnancy diet on childhood diet was decomposed into direct and indirect effect using mediation analysis. Maternal pregnancy and post-natal diet were both correlated with child diet for overall diet quality and fruit and vegetable variety (P < 0.001). Mediation analyses showed that the indirect effect of maternal pregnancy diet on child diet was mediated through maternal post-natal diet, particularly for fruit (P = 0.045) and vegetables (P = 0.055). Nutrition intervention should therefore be aimed at improving diet quality and variety in mothers with young children, in order to subsequently improve eating habits of offspring. © 2014 John Wiley & Sons Ltd.

Injury severity after traumatic brain injury (TBI) is a well-established risk factor for the development of post-traumatic epilepsy (PTE). However, whether lesion location influences the susceptibility of seizures and development of PTE longitudinally has yet to be defined. We hypothesized that lesion location, specifically in the temporal lobe, would be associated with an increased incidence of both early seizures and PTE. As secondary analysis measures, we assessed the degree of brain atrophy and functional recovery, and performed a between-group analysis, comparing patients who developed PTE with those who did not develop PTE. We assessed early seizure incidence (n = 90) and longitudinal development of PTE (n = 46) in a prospective convenience sample of patients with moderate-severe TBI. Acutely, patients were monitored with prospective cEEG and a high-resolution Magnetic Resonance Imaging (MRI) scan for lesion location classification. Chronically, patients underwent a high-resolution MRI, clinical assessment, and were longitudinally monitored for development of epilepsy for a minimum of 2 years post-injury. Early seizures, occurring within the first week post-injury, occurred in 26.7% of the patients (n = 90). Within the cohort of subjects who had evidence of early seizures (n = 24), 75% had a hemorrhagic temporal lobe injury on admission. For longitudinal analyses (n = 46), 45.7% of patients developed PTE within a minimum of 2 years post-injury. Within the cohort of subjects who developed PTE (n = 21), 85.7% had a hemorrhagic temporal lobe injury on admission and 38.1% had early (convulsive or non-convulsive) seizures on cEEG monitoring during their acute ICU stay. In a between-group analysis, patients with PTE (n = 21) were more likely than patients who did not develop PTE (n = 25) to have a hemorrhagic temporal lobe injury (p < 0.001), worse functional recovery (p = 0.003), and greater temporal lobe atrophy (p�

Although the skeletal muscle in the region of the third lumbar vertebra (L3) is generally assessed in order to judge sarcopenia, not every patient with non-small cell lung cancer (NSCLC) undergoes computed tomography including the L3 region. We hypothesized that immuno-nutritional parameters could predict the existence of sarcopenia in patients with NSCLC. The aim of this study was to retrospectively investigate the correlation between preoperative sarcopenia and immuno-nutritional parameters in patients with early-stage NSCLC. We selected 147 of patients with pathological stage I NSCLC who underwent preoperative measurement of immuno-nutritional parameters and CT including the L3 region. Preoperative sarcopenia was significantly associated with female gender (p=0.0003) and poor prognosis (p=0.0322). In Kaplan-Meier analysis of overall survival (OS) by preoperative sarcopenia status, the sarcopenic group had significantly shorter OS than the non-sarcopenic group (5-year OS: 87.27% vs. 77.37%, p=0.0131, log-rank test). In multivariate analysis, the preoperative sarcopenia status (hazard ratio=5.138; 95% confidence interval=2.305-11.676; p<0.0001) was an independent prognostic factor. Preoperative sarcopenia status was significantly related to controlling nutritional status score (p=0.0071) and Geriatric Nutritional Risk Index (GNRI) (p<0.0001). Spearman's correlation test showed good significant correlation between preoperative sarcopenia status and GNRI (r=0.348, p<0.0001). The preoperative GNRI is a simple and useful predictor for existence of preoperative sarcopenia which was associated with poor outcome in patients with early-stage NSCLC.

Collagen cross-linking (CXL) for post-laser-assisted in situ keratomileusis (LASIK) ectasia (PLE) is traditionally performed either epi-on or epi-off on the corneal surface. This study describes a novel technique in treating early PLE with under-flap CXL (ufCXL) to the stromal bed and reports on 6-month outcomes. Case series of seven patients (eight eyes) with topography-diagnosed early PLE treated with ufCXL. Inclusion criteria were early, mild PLE defined as new-onset postoperative manifest refraction cylinder ≤1.50 D, with new topographic inferior steepening consistent with ectasia, uncorrected distance visual acuity (UDVA) of 20/40 or better, and corrected distance visual acuity (CDVA) of 20/25 or better. Existing LASIK flap was lifted, riboflavin was applied directly to the stromal bed, flap was repositioned, and 18 mW/cm 2 ultraviolet light was applied for 3 minutes to the corneal surface. Post-ufCXL manifest refraction, UDVA and CDVA, corneal cylinder, K max , and corneal irregularity index were compared with pre-ufCXL measurements. Patients had a pre-ufCXL sphere of 0.09±0.48 D and cylinder of -0.78±0.49 D. At 6 months, post-ufCXL sphere (0.06±0.8 D; P =0.89) and cylinder (-1.09±0.76 D, P =0.26) were unchanged. Cumulative post-ufCXL UDVA was unchanged, achieving 20/20, 20/30, and 20/40 in 25%, 88%, and 88%, respectively, compared with 13%, 63%, and 88% pre-ufCXL ( P =0.68). Post-ufCXL CDVA was unchanged ( P =0.93) with a gain of one line in two eyes, a loss of one line in one eye, and five eyes unchanged. The efficacy index ( P =0.76), safety index ( P =0.89), K max ( P =0.94), and corneal irregularity index ( P =0.73) were also unchanged. Preliminary results with ufCXL for early PLE are promising, demonstrating maintenance of visual accuracy, efficacy, safety, K max , and cylinder, with much quicker recovery times than surface CXL.

Nutrition considerations in traumatic brain injury.

PubMed

Cook, Aaron M; Peppard, Amy; Magnuson, Barbara

The provision of adequate nutrition support for patients with traumatic brain injury (TBI) has been a clinical challenge for decades. The primary and secondary injuries create unique metabolic derangements along with accompanying issues such as optimal timing and route of nutrition, appropriate fluid and electrolytes, drug administration, rehabilitation, and dysphagia. Enteral nutrition is clearly established as the preferential route of nutrition support for this population vs parenteral nutrition. There appears to be a consensus on early initiation of enteral nutrition, but less definitive are recommendations on advancement timing and formula components. Nutrition therapies should include exact fluid resuscitation goals specific for TBI and strict electrolyte monitoring to avoid extreme fluid, electrolyte, or glucose shifts that could be detrimental to the patient. While the critical care patient often tolerates small bowel feeding, the long-term rehabilitation patient should transition to and tolerate gastric feeding. Drug-nutrient and adverse drug reactions such as diarrhea should be routinely evaluated in patients receiving enteral nutrition. Monitoring for dysphagia is critical to avoid the costly negative aspects associated with aspiration and to capitalize on quality of life and appropriate oral nutrition. Emphasizing the priority of early nutrition support within a multi-disciplinary team may be the critical key for successful provision and tolerance of nutrition support in the TBI population.

Natal dispersal patterns are not associated with inbreeding avoidance in the Seychelles warbler.

In this study, we test whether patterns of territory inheritance, social mate choice and female-biased natal dispersal act as inbreeding avoidance mechanisms in the cooperatively breeding Seychelles warbler. Our results show that Seychelles warblers do not reduce the likelihood of inbreeding by avoiding related individuals as mates. The occurrence of natural and experimentally induced territory inheritance did not depend on whether the remaining breeder was a parent of the potential inheritor or an unrelated breeder. Furthermore, dispersing individuals were no less related to their eventual mates than expected given the pool of candidates they could mate with. The female bias in natal dispersal distance observed in the Seychelles warbler does not facilitate inbreeding avoidance because, contrary to our prediction, there was no sex difference in the clustering of related opposite sex breeders around the natal territories of dispersers. As a result, the chance of females mating with relatives was not reduced by their greater dispersal distance compared with that of males.

In surgery, indications for artificial nutrition comprise prevention and treatment of catabolism and malnutrition. Thus in general, food intake should not be interrupted postoperatively and the re-establishing of oral (e.g. after anastomosis of the colon and rectum, kidney transplantation) or enteral food intake (e.g. after an anastomosis in the upper gastrointestinal tract, liver transplantation) is recommended within 24 h post surgery. To avoid increased mortality an indication for an immediate postoperatively artificial nutrition (enteral or parenteral nutrition (PN)) also exists in patients with no signs of malnutrition, but who will not receive oral food intake for more than 7 days perioperatively or whose oral food intake does not meet their needs (e.g. less than 60–80%) for more than 14 days. In cases of absolute contraindication for enteral nutrition, there is an indication for total PN (TPN) such as in chronic intestinal obstruction with a relevant passage obstruction e.g. a peritoneal carcinoma. If energy and nutrient requirements cannot be met by oral and enteral intake alone, a combination of enteral and parenteral nutrition is indicated. Delaying surgery for a systematic nutrition therapy (enteral and parenteral) is only indicated if severe malnutrition is present. Preoperative nutrition therapy should preferably be conducted prior to hospital admission to lower the risk of nosocomial infections. The recommendations of early postoperative re-establishing oral feeding, generally apply also to paediatric patients. Standardised operative procedures should be established in order to guarantee an effective nutrition therapy. PMID:20049072

Evidence for geomagnetic imprinting and magnetic navigation in the natal homing of sea turtles.

Brothers, J Roger; Lohmann, Kenneth J

Natal homing is a pattern of behavior in which animals migrate away from their geographic area of origin and then return to reproduce in the same location where they began life [1-3]. Although diverse long-distance migrants accomplish natal homing [1-8], little is known about how they do so. The enigma is epitomized by loggerhead sea turtles (Caretta caretta), which leave their home beaches as hatchlings and migrate across entire ocean basins before returning to nest in the same coastal area where they originated [9, 10]. One hypothesis is that turtles imprint on the unique geomagnetic signature of their natal area and use this information to return [1]. Because Earth's field changes over time, geomagnetic imprinting should cause turtles to change their nesting locations as magnetic signatures drift slightly along coastlines. To investigate, we analyzed a 19-year database of loggerhead nesting sites in the largest sea turtle rookery in North America. Here we report a strong association between the spatial distribution of turtle nests and subtle changes in Earth's magnetic field. Nesting density increased significantly in coastal areas where magnetic signatures of adjacent beach locations converged over time, whereas nesting density decreased in places where magnetic signatures diverged. These findings confirm central predictions of the geomagnetic imprinting hypothesis and provide strong evidence that such imprinting plays an important role in natal homing in sea turtles. The results give credence to initial reports of geomagnetic imprinting in salmon [11, 12] and suggest that similar mechanisms might underlie long-distance natal homing in diverse animals.

To assess the impact of early introduction of enteral nutrition therapy in reducing morbidity and mortality in pediatric intensive care unit. Search in the literature of the last 10 years, in English and the target population of individuals aged 1 month to 18 years admitted to pediatric intensive care units in the databases PubMed, Lilacs and Embase using the keywords: Critical Care, Nutritional Support and Nutrition Disorders or Malnutrition. Despite advances in the quality of clinical care, the prevalence of malnutrition in hospitalized children remains unchanged in the last 20 years (15-30%) and has implications for the time of admission, course of illness and morbidity. Malnutrition is common and is often poorly recognized and therefore, untreated. Nutritional therapy is an essential part in the treatment of pediatric patients who have severely ill hypercatabolic state protein, which can be minimized with an effective nutritional treatment plan. In this study, we reviewed publications which have shown that there is still a paucity of randomized and controlled studies with good statistical treatment in relation to enteral nutritional therapy with outcomes related to morbidity and mortality. The current guidelines for nutritional therapy in these patients are largely based on expert opinion and data extrapolated from adult studies and studies in healthy children. The scientific evidence on the use of enteral nutrition therapy in improving the development of critically ill pediatric patients is still scarce and further studies are needed focusing on it, and better guidelines must be formulated.

Direct evidence for human exploitation of birds in the Middle Stone Age of South Africa: The example of Sibudu Cave, KwaZulu-Natal.

Val, Aurore; de la Peña, Paloma; Wadley, Lyn

2016-10-01

Here, we present direct taphonomic evidence for the exploitation of birds by hunter-gatherers in the Middle Stone Age of South Africa as far as ∼77 ka. The bird assemblage from Sibudu Cave, KwaZulu-Natal, was analysed for bone surface modifications. Cut-marks associated with skinning, defleshing, and disarticulation, perforations on distal humeri produced during disarticulation of the forewing, peeling, and human tooth marks were observed on bird bones (i.e., mostly pigeons, doves, Galliformes, waders, and raptors) recovered from pre-Still Bay, Still Bay, Howiesons Poort, and post-Howiesons Poort techno-complexes. We conducted experiments to butcher, disarticulate, cook, and consume pigeon and dove carcasses, in order to create a comparative collection of bone surface modifications associated with human consumption of these birds. Human/bird interactions can now be demonstrated outside of Europe and prior to 50 ka. The evidence sheds new light on Middle Stone Age subsistence strategies in South Africa and introduces a fresh argument to the debate regarding the early emergence of behaviours usually associated with Later Stone Age hunter-gatherers.

Stunting and poor child development are major public health concerns in Malawi. Integrated nutrition and early child development (ECD) interventions have shown potential to reduce stunting, but it is not known how these integrated approaches can be implemented in Malawi. In this paper, we aimed to evaluate the current jobs status of community health workers and their potential to implement integrated approaches. This was accomplished by a desk review of nutrition and ECD policy documents, as well as interviews with key informants, community health workers, and community members. We found that Malawi has comprehensive policies and well-outlined coordination structures for nutrition and ECD that advocate for integrated approaches. Strong multidisciplinary interaction exists at central levels but not at the community level. Integration of community health workers from different sectors is limited by workload, logistics, and a lack of synchronized work schedules. Favorable, sound policies and well-outlined coordination structures alone are not enough for the establishment of integrated nutrition and ECD activities. Balanced bureaucratic structures, improved task allocation, and synchronization of work schedules across all relevant sectors are needed for integrated intervention in Malawi. © 2014 New York Academy of Sciences.

The aim of this analysis was to determine the risk of malnutrition and the prognostic value of nutritional intervention in patients affected by pancreatic ductal adenocarcinoma (PDAC) undergoing chemotherapy. Clinical-pathological and nutritional data were correlated with overall survival (OS) using a Cox model. Nutritional status was determined by Malnutrition Universal Screening Tool (MUST), body mass index, weight loss in the past 6 months, presence of nutrition-related symptoms, and current energy intake. Nutritional intervention included appropriate individual dietary counseling. Data from 109 patients were gathered (median age 63 years). The majority of patients (64.2%) presented a MUST value of ≥ 2, corresponding to a high risk of malnutrition. At multivariate analysis for OS in locally advanced and metastatic PDAC patients, the time between the diagnosis and the nutritional intervention (HR 2.22, p = 0.017), the performance status (HR 1.38, p = 0.075), the surgery of the primary (HR 5.89, p = 0.005), and the response to the first line (HR 5.9, p = 0.03) were independent significant predictors of outcome. Furthermore, a weight gain > 2% from the baseline weight was correlated with the time between the diagnosis and the nutritional intervention (p = 0.021): in patients receiving a nutritional support within 3 months from diagnosis, a 2% weight gain was associated with a 2-year OS benefit (50.3% vs. 33.0%, p = 0.04). This analysis suggests that the early nutritional support may contribute to influence the prognosis of patients affected by advanced PDAC undergoing chemotherapy.

2015-04-01

Students may be receiving less than an average of 4 hours of nutrition instruction per year. Integrating nutrition with other subject areas such as science may increase exposure to nutrition education, while supporting existing academics. During the 2009-2010 school year, researchers implemented the Food, Math, and Science Teaching Enhancement Resource (FoodMASTER) Intermediate (FMI) curriculum in 18 fourth-grade classrooms, whereas 16 classrooms served as comparison. FMI is a hands-on, integrative curriculum for children in grades 3-5 that uses food as a tool to teach mathematics and science. Researchers developed a 28-item multiple-choice questionnaire to assess students' nutrition knowledge in 6 content areas. Students were evaluated at baseline and post-intervention. Data were analyzed using independent t tests. Analysis of covariance was employed to control for differences at baseline when assessing the effectiveness of the FMI curriculum to increase nutrition knowledge. A significant improvement was observed in total nutrition knowledge at post-intervention (adjusting for baseline) between groups (F [1] = 128.95; p < .01) and in all content areas post-intervention. Findings from this study suggest teachers were successfully able to integrate science and nutrition to meet multiple academic standards. More specifically, results showed implementation of the integrative FMI curriculum effectively improved fourth-graders' nutrition knowledge compared with students not exposed to FMI. © 2015, American School Health Association.

To assess the nutritional status and dietary practices among underprivileged pregnant women, identify the lacune, outline implement and assess the effect of nutritional counseling on their dietary intake, anthropometric status and anemia status. Hundred pregnant women belonging to low socio-economic status were interviewed. Based on lacune, nutrition education (NE) was given in the form of simple messages to 50 subjects (NE-group) over 10-16 weeks period, while the remaining 50 formed the comparison group (Non-NE group). Tools used were individual counseling, weekly home visits and group meetings. Anthropometric measurements taken were height and weight. Dietary data was collected using 24-hour recall and food frequency questionnaire. Hemoglobin estimation was done. Effect of intervention was assessed by monitoring changes in dietary practices, weight gain, and nutritional status of the subjects. Baseline findings--low mean maternal body weight (51.05 +/- 7.26 kg), 96.3% anemia prevalence and severely sub-optimal dietary intakes. Post-NE results revealed a significant increase in quality and quantity of the diets consumed. Mean hemoglobin levels significantly increased (Post-NE vs Non-NE = 9.65 +/- 0.97 vs 7.85 +/- 1.58, p < 0.001) and anemia prevalence reduced (Post-NE vs Non-NE = 78.7% vs 96%) in post-NE group. Individual counseling with weekly reinforcement can bring about improvement in nutritional status during pregnancy.

Calorie restriction and corticosterone elevation during lactation can each modulate adult male fear and anxiety-like behaviour.

2014-09-01

Early life events, such as calorie restriction (CR) and elevated glucocorticoids, can calibrate the lifelong behavioural and physiological profile of an individual. Stress reactivity in adulthood is particularly sensitive to early life events; however, the consequence to fear and anxiety-like behaviour is less clear. Consequently, the current study sought to examine the effects of post-natal CR and glucocorticoid elevation, long considered powerful programming stimuli, on the subsequent fear and anxiety behaviour of the adult offspring. Rat dams received either corticosterone (200 μg/ml) supplementation in drinking water (CORT) or a 25% CR from post-natal day (PND) 1 to 11. Responses to the elevated plus maze (EPM), open field and a predator odour (TMT; 2,5-dihydro-2,4,5-trimethylthiazoline) were characterised in the adult male offspring. Both treatment conditions resulted in enhanced fear responses to TMT, characterised by heightened risk assessment and increased avoidance of TMT. CORT nursed offspring further demonstrated an anxiogenic profile in the open field. Basal hypothalamic-pituitary-adrenal function was unchanged in CORT adult offspring, whilst corticosterone concentration was elevated by post-natal CR. CR and CORT treated dams both exhibited greater anxiety-like behaviour in the EPM. A modest and temporary enhancement of maternal care was observed in CR and CORT treated dams, with CR dams further exhibiting rapid pup retrieval latencies. The results indicate enhanced emotionality in the adult male progeny of dams exposed to CR and corticosterone supplementation during the post-natal period. The modest enhancement of maternal care observed by both treatments is unlikely to have influenced the behavioural profile of the offspring. Copyright © 2014. Published by Elsevier Inc.

Association of marital status and years of schooling with perinatal outcome: the influence of pre-natal care as an intermediate variable.

Faundes, A; Hardy, E; Diaz, J; Pinotti, J

1982-01-01

The association between mother's education and perinatal mortality, and between marital status and proportion of preterm deliveries was analyzed using data from 20,000 women and newborns delivered at the Hospital Barros Luco-Trudeau in Santiago, Chile. A highly significant correlation was found, but after being controlled by pre-natal care, that association disappeared for those mothers with good pre-natal care, remaining only as a part of the association for women who did not attend the pre-natal clinics or did not follow minimal standards of care. The definition used for "good pre-natal care" was much less demanding than WHO recommendation. We required a minimum of only 5 visits, starting before the 5th month of the pregnancy and with blood pressure and body weight registered at each visit. Pre-natal assistance was provided mostly by registered midwives, with occasional consultation by physicians. The efficiency of a low cost health activity, such as pre-natal care, in improving infant health is held in contrast with the inefficiency of high cost technology when applied to developing countries' health problems.

The Natal valley (South Mozambique margin) is a key area for the understanding of the SW Indian Ocean history since the Gondwana break-up, and widely, the structure of a margin system at the transition between divergent and strike-slip segments. As one part of the PAMELA project (PAssive Margins Exploration Laboratories), conducted by TOTAL, IFREMER, in collaboration with Université de Bretagne Occidentale, Université Rennes 1, Université Pierre and Marie Curie, CNRS et IFPEN, the Natal Valley and the East Limpopo margin have been explored during the MOZ3/5 cruise (2016), conducted onboard the R/V Pourquoi Pas?, through the acquisition of 7 wide-angle profiles and coincident marine multichannel (720 traces) seismic as well as potential field data. Simultaneously, land seismometers were deployed in the Mozambique coastal plains, extending six of those profiles on land for about 100 km in order to provide information on the onshore-offshore transition. Wide-angle seismic data are of major importance as they can provide constrains on the crustal structure of the margin and the position of the continent-ocean boundary in an area where the crustal nature is poorly known and largely controversial. The aim of this work is to present the first results on the crustal structure from P-waves velocity modeling along two perpendicular MZ1 & MZ7 wide-angle profiles crossing the Natal Valley in an E-W and NNW-SSE direction respectively, which reveal a crust up to 30 km thick below the Natal Valley and thus raises questions of a purely oceanic origin of the Valley. The post-doc of Angélique Leprêtre is co-funded by TOTAL and IFREMER as part of the PAMELA (Passive Margin Exploration Laboratories) scientific project.

Background : Post-earthquake studies from around the world have reported that survivors relying on emergency food for prolonged periods of time experienced several dietary related health problems. The present study aimed to quantify the potential nutrient production of urban agricultural vegetables and the resulting nutritional self-sufficiency throughout the year for mitigating post-disaster situations. Methods : We estimated the vegetable production of urban agriculture throughout the year. Two methods were developed to capture the production from professional and hobby farms: Method I utilized secondary governmental data on agricultural production from professional farms, and Method II was based on a supplementary spatial analysis to estimate the production from hobby farms. Next, the weight of produced vegetables [t] was converted into nutrients [kg]. Furthermore, the self-sufficiency by nutrient and time of year was estimated by incorporating the reference consumption of vegetables [kg], recommended dietary allowance of nutrients per capita [mg], and population statistics. The research was conducted in Nerima, the second most populous ward of Tokyo's 23 special wards. Self-sufficiency rates were calculated with the registered residents. Results : The estimated total vegetable production of 5660 tons was equivalent to a weight-based self-sufficiency rate of 6.18%. The average nutritional self-sufficiencies of Methods I and II were 2.48% and 0.38%, respectively, resulting in an aggregated average of 2.86%. Fluctuations throughout the year were observed according to the harvest seasons of the available crops. Vitamin K (6.15%) had the highest self-sufficiency of selected nutrients, while calcium had the lowest (0.96%). Conclusions : This study suggests that depending on the time of year, urban agriculture has the potential to contribute nutrients to diets during post-disaster situations as disaster preparedness food. Emergency responses should be targeted

Intestinal development during late embryogenesis and early post-hatch has a long-term influence on digestive and absorptive capacity in chickens. The objective of this research was to obtain a global view of intestinal solute carrier (SLC) gene family member expression from late embryogenesis until 2 weeks post-hatch with a focus on SLC genes involved in uptake of sugars and amino acids. Small intestine samples from male chicks were collected on embryonic days 18 (E18) and 20 (E20), day of hatch and days 1, 3, 7 and 14 post-hatch. The expression profiles of 162 SLC genes belonging to 41 SLC families were determined using Affymetrix chicken genome microarrays. The majority of SLC genes showed little or no difference in level of expression during E18-D14. A number of well-known intestinal transporters were upregulated between E18 and D14 including the amino acid transporters rBAT, y(+)LAT-2 and EAAT3, the peptide transporter PepT1 and the sugar transporters SGLT1, GLUT2 and GLUT5. The amino acid transporters CAT-1 and CAT-2 were downregulated. In addition, several glucose and amino acid transporters that are novel to our understanding of nutrient absorption in the chicken intestine were discovered through the arrays (SGLT6, SNAT1, SNAT2 and AST). These results represent a comprehensive characterization of the expression profiles of the SLC family of genes at different stages of development in the chicken intestine and lay the ground work for future nutritional studies.

Records of pan (floodplain wetland) sedimentation as an approach for post-hoc investigation of the hydrological impacts of dam impoundment: The Pongolo river, KwaZulu-Natal.

PubMed

Heath, S K; Plater, A J

2010-07-01

River impoundment by dams has far-reaching consequences for downstream floodplains in terms of hydrology, water quality, geomorphology, ecology and ecosystem services. With the imperative of economic development, there is the danger that potential environmental impacts are not assessed adequately or monitored appropriately. Here, an investigation of sediment composition of two pans (floodplain wetlands) in the Pongolo River floodplain, KwaZulu-Natal, downstream of the Pongolapoort dam constructed in 1974, is considered as a method for post-hoc assessment of the impacts on river hydrology, sediment supply and water quality. Bumbe and Sokhunti pans have contrasting hydrological regimes in terms of their connection to the main Pongolo channel - Bumbe is a shallow ephemeral pan and Sokhunti is a deep, perennial water body. The results of X-ray fluorescence (XRF) geochemical analysis of their sediment records over a depth of >1 m show that whilst the two pans exhibit similar sediment composition and variability in their lower part, Bumbe pan exhibits a shift toward increased fine-grained mineral supply and associated nutrient influx at a depth of c. 45 cm whilst Sokhunti pan is characterised by increased biogenic productivity at a depth of c. 26 cm due to enhanced nutrient status. The underlying cause is interpreted as a shift in hydrology to a 'post-dam' flow regime of reduced flood frequencies with more regular baseline flows which reduce the average flow velocity. In addition, Sokhunti shows a greater sensitivity to soil influx during flood events due to the nature of its 'background' of autochthonous biogenic sedimentation. The timing of the overall shift in sediment composition and the dates of the mineral inwash events are not well defined, but the potential for these wetlands as sensitive recorders of dam-induced changes in floodplain hydrology, especially those with a similar setting to Sokhunti pan, is clearly demonstrated.

2014-03-01

This study aims at providing an insight into early handling procedures on learning and memory performance in adult female rats. Early handling procedures were started on post-natal day 2 until 21, and consisted in 15 min, daily separations of the dams from their litters. Assessment of declarative memory was carried out in the novel-object recognition task; spatial learning, reference- and working memory were evaluated in the Morris water maze (MWM). Our results indicate that early handling induced an enhancement in: (1) declarative memory, in the object recognition task, both at 1h and 24h intervals; (2) reference memory in the probe test and working memory and behavioral flexibility in the "single-trial and four-trial place learning paradigm" of the MWM. Short-term separation by increasing maternal care causes a dampening in HPA axis response in the pups. A modulated activation of the stress response may help to protect brain structures, involved in cognitive function. In conclusion, this study shows the long-term effects of a brief maternal separation in enhancing object recognition-, spatial reference- and working memory in female rats, remarking the impact of early environmental experiences and the consequent maternal care on the behavioral adaptive mechanisms in adulthood.

Neutron Star Natal Kick and Jets in Core Collapse Supernovae

NASA Astrophysics Data System (ADS)

Bear, Ealeal; Soker, Noam

2018-03-01

We measure the angle between the neutron star (NS) natal kick direction and the inferred direction of jets according to the morphology of 12 core collapse supernova remnants (SNR), and find that the distribution is almost random, but missing small angles. The 12 SNRs are those for which we could both identify morphological features that we can attribute to jets and for which the direction of the NS natal kick is given in the literature. Unlike some claims for spin-kick alignment, here we rule out jet-kick alignment. We discuss the cumulative distribution function of the jet-kick angles under the assumption that dense clumps that are ejected by the explosion accelerate the NS by the gravitational attraction, and suggest that the jet feedback explosion mechanism might in principle account for the distribution of jet-kick angles.

Is a Nutrition Education Intervention Associated with a Higher Intake of Fruit and Vegetables and Improved Nutritional Knowledge among Housewives in Mauritius?

2016-11-29

The purpose of the study was to assess the determinants of nutrition behaviors and body mass index and determine the impact of a nutrition education intervention (NEI) among Mauritian housewives. A pretest-posttest design was used assessing Nutrition Knowledge (NK), Nutrition Attitudes, Fruit and Vegetable Intake (FVI), body mass index (BMI). Two hundred Mauritian housewives were recruited. The NEI was in the form of a lecture and lasted for twenty minutes. Statistical tests performed revealed that the mean NK score at baseline was 65.8 ± 6.92 and a significant increase of +17.1 at post-test and +16.1 at follow-up was observed. Determinants of NK were age, presence of elderly people, and BMI. Mean nutrition attitude score at baseline was 2.37 ± 0.22 with significant increase of +0.2 (post-test) and +0.17 at follow-up. Age, level of education, presence of elders, and NK were linked to a positive attitude. FVI was predicted by age, income, presence of elders, NK, and nutrition attitudes. Baseline FVI was 4.77 ± 1.11 which increased significantly ( p < 0.001) to 4.98 ± 1.13 at post-test and 5.03 ± 1.20 at follow up. NEI had a positive impact suggesting the benefits of such intervention in the promotion of healthy nutrition behaviors.

Early life programming of fear conditioning and extinction in adult male rats.

The early rearing environment programs corticolimbic function and neuroendocrine stress reactivity in adulthood. Although early environmental programming of innate fear has been previously examined, its impact on fear learning and memory later in life remains poorly understood. Here we examined the role of the early rearing environment in programming fear conditioning and extinction in adult male rats. Pups were subjected to maternal separation (MS; 360 min), brief handling (H; 15 min), or animal facility rearing (AFR) on post-natal days 2-14. As adults, animals were tested in a 3-day fear learning and memory paradigm which assessed the acquisition, expression and extinction of fear conditioning to an auditory cue; the recall of extinction was also assessed. In addition, contextual fear was assessed prior to cued extinction and its recall. We found that the acquisition of fear conditioning to the cue was modestly impaired by MS. However, no early rearing group differences were observed in cue-induced fear expression. In contrast, both the rate of extinction and extinction recall were attenuated by H. Finally, although contextual fear was reduced after extinction to the cue, no differences in context-induced fear were observed between the early rearing groups. These results add to a growing body of evidence supporting an important role for early environmental programming of fear conditioning and extinction. They also indicate that different early rearing conditions can program varying effects on distinct fear learning and memory processes in adulthood.

2017-01-01

Background: High-intensity interval training (HIIT) can improve several aspects of cardiometabolic health. Previous studies have suggested that adaptations to exercise training can be augmented with post-exercise milk or protein consumption, but whether this nutritional strategy can impact the cardiometabolic adaptations to HIIT in type 2 diabetes is unknown. Objective: To determine if the addition of a post-exercise milk or protein beverage to a high-intensity interval training (HIIT) intervention improves cardiometabolic health in individuals with type 2 diabetes. Design: In a proof-of-concept, double-blind clinical trial 53 adults with uncomplicated type 2 diabetes were randomized to one of three nutritional beverages (500 mL skim-milk, macronutrient control, or flavored water placebo) consumed after exercise (3 days/week) during a 12 week low-volume HIIT intervention. HIIT involved 10 X 1-min high-intensity intervals separated by 1-min low-intensity recovery periods. Two sessions per week were cardio-based (at ~90% of heart rate max) and one session involved resistance-based exercises (at RPE of 5-6; CR-10 scale) in the same interval pattern. Continuous glucose monitoring (CGM), glycosylated hemoglobin (HbA 1c ), body composition (dual-energy X-ray absorptiometry), cardiorespiratory fitness ([Formula: see text]), blood pressure, and endothelial function (%FMD) were measured before and after the intervention. Results: There were significant main effects of time (all p < 0.05) but no difference between groups (Interaction: all p > 0.71) for CGM 24-h mean glucose (-0.5 ± 1.1 mmol/L), HbA 1c (-0.2 ± 0.4%), percent body fat (-0.8 ± 1.6%), and lean mass (+1.1 ± 2.8 kg). Similarly, [Formula: see text] (+2.5 ± 1.6 mL/kg/min) and %FMD (+1.4 ± 1.9%) were increased, and mean arterial blood pressure reduced (-6 ± 7 mmHg), after 12 weeks of HIIT (all p < 0.01) with no difference between beverage groups (Interaction: all p > 0.11).

Evaluate neonatal management and outcome of neonates with either a prenatal or a post-natal diagnosis of EA type III. Population-based study using data from the French National Register for EA from 2008 to 2010. We compared children with prenatal versus post-natal diagnosis in regards to prenatal, maternal and neonatal characteristics. We define a composite variable of morbidity (anastomotic esophageal leaks, recurrent fistula, stenosis) and mortality at 1 year. Four hundred and eight live births with EA type III were recorded with a prenatal diagnosis rate of 18.1%. Transfer after birth was lower in prenatal subset (32.4% versus 81.5%, P<0.001). Delay between birth and first intervention was not significantly different. Defect size (2cm vs 1.4cm, P<0.001), gastrostomy (21.6% versus 8.7%, P<0.001) and length in neonatal unit care were higher in prenatal subset (47.9 days versus 33.6 days, P<0.001). The composite variables were higher in prenatal diagnosis subset (38.7% vs 26.1%, P=0.044). Despite the excellent survival rate of EA, cases with antenatal detection have a higher morbidity related to the EA type (longer gap). Even if it does not modify neonatal management and 1-year outcome, prenatal diagnosis allows antenatal parental counseling and avoids post-natal transfer. Copyright © 2014 Elsevier Masson SAS.

Early chronic lead exposure continues to pose serious health risks for children, particularly those living in lower socioeconomic environments. This study examined effects on developing glomeruli in young C57BL/6J mice exposed to low (30 ppm), higher (330 ppm) or no lead via dams’ drinking water from birth to sacrifice on post-natal day 28. Low-level lead exposed mice [BLL mean (SD); 3.19 (0.70) μg/dL] had an increase in glomerular volume but no change in podocyte number compared to control mice [0.03 (0.01) μg/dL]. Higher-level lead exposed mice [14.68 (2.74) μg/dL] had no change in either glomerular volume or podocyte number. The increase in glomerular volume was explained by increases in glomerular capillary and mesangial volumes with no change in podocyte volume. Early chronic lead exposure yielding very low blood lead levels alters glomerular development in pre-adolescent animals. PMID:24300173

Purpose Collagen cross-linking (CXL) for post-laser-assisted in situ keratomileusis (LASIK) ectasia (PLE) is traditionally performed either epi-on or epi-off on the corneal surface. This study describes a novel technique in treating early PLE with under-flap CXL (ufCXL) to the stromal bed and reports on 6-month outcomes. Patients and methods Case series of seven patients (eight eyes) with topography-diagnosed early PLE treated with ufCXL. Inclusion criteria were early, mild PLE defined as new-onset postoperative manifest refraction cylinder ≤1.50 D, with new topographic inferior steepening consistent with ectasia, uncorrected distance visual acuity (UDVA) of 20/40 or better, and corrected distance visual acuity (CDVA) of 20/25 or better. Existing LASIK flap was lifted, riboflavin was applied directly to the stromal bed, flap was repositioned, and 18 mW/cm2 ultraviolet light was applied for 3 minutes to the corneal surface. Post-ufCXL manifest refraction, UDVA and CDVA, corneal cylinder, Kmax, and corneal irregularity index were compared with pre-ufCXL measurements. Results Patients had a pre-ufCXL sphere of 0.09±0.48 D and cylinder of −0.78±0.49 D. At 6 months, post-ufCXL sphere (0.06±0.8 D; P=0.89) and cylinder (−1.09±0.76 D, P=0.26) were unchanged. Cumulative post-ufCXL UDVA was unchanged, achieving 20/20, 20/30, and 20/40 in 25%, 88%, and 88%, respectively, compared with 13%, 63%, and 88% pre-ufCXL (P=0.68). Post-ufCXL CDVA was unchanged (P=0.93) with a gain of one line in two eyes, a loss of one line in one eye, and five eyes unchanged. The efficacy index (P=0.76), safety index (P=0.89), Kmax (P=0.94), and corneal irregularity index (P=0.73) were also unchanged. Conclusion Preliminary results with ufCXL for early PLE are promising, demonstrating maintenance of visual accuracy, efficacy, safety, Kmax, and cylinder, with much quicker recovery times than surface CXL.

To ensure sustainability of aquaculture, plant-based ingredients are being used in feeds to replace marine-derived products. However, plants contain secondary metabolites which can affect food intake and nutrient utilisation of fish. The application of nutritional stimuli during early development can induce long-term changes in animal physiology. Recently, we successfully used this approach to improve the utilisation of plant-based diets in diploid and triploid Atlantic salmon. In the present study we explored the molecular mechanisms occurring in the liver of salmon when challenged with a plant-based diet in order to determine the metabolic processes affected, and the effect of ploidy. Microarray analysis revealed that nutritional history had a major impact on the expression of genes. Key pathways of intermediary metabolism were up-regulated, including oxidative phosphorylation, pyruvate metabolism, TCA cycle, glycolysis and fatty acid metabolism. Other differentially expressed pathways affected by diet included protein processing in endoplasmic reticulum, RNA transport, endocytosis and purine metabolism. The interaction between diet and ploidy also had an effect on the hepatic transcriptome of salmon. The biological pathways with the highest number of genes affected by this interaction were related to gene transcription and translation, and cell processes such as proliferation, differentiation, communication and membrane trafficking. The present study revealed that nutritional programming induced changes in a large number of metabolic processes in Atlantic salmon, which may be associated with the improved fish performance and nutrient utilisation demonstrated previously. In addition, differences between diploid and triploid salmon were found, supporting recent data that indicate nutritional requirements of triploid salmon may differ from those of their diploid counterparts.

In the human brain, the morphology of cortical gyri and sulci is complex and variable among individuals, and it may reflect pathological functioning with specific abnormalities observed in certain developmental and neuropsychiatric disorders. Since cortical folding occurs early during brain development, these structural abnormalities might be present long before the appearance of functional symptoms. So far, the precise mechanisms responsible for such alteration in the convolution pattern during intra-uterine or post-natal development are still poorly understood. Here we compared anatomical and functional brain development in vivo among 45 premature newborns who experienced different intra-uterine environments: 22 normal singletons, 12 twins and 11 newborns with intrauterine growth restriction (IUGR). Using magnetic resonance imaging (MRI) and dedicated post-processing tools, we investigated early disturbances in cortical formation at birth, over the developmental period critical for the emergence of convolutions (26-36 weeks of gestational age), and defined early 'endophenotypes' of sulcal development. We demonstrated that twins have a delayed but harmonious maturation, with reduced surface and sulcation index compared to singletons, whereas the gyrification of IUGR newborns is discordant to the normal developmental trajectory, with a more pronounced reduction of surface in relation to the sulcation index compared to normal newborns. Furthermore, we showed that these structural measurements of the brain at birth are predictors of infants' outcome at term equivalent age, for MRI-based cerebral volumes and neurobehavioural development evaluated with the assessment of preterm infant's behaviour (APIB).

Natal habitat imprinting counteracts the diversifying effects of phenotype-dependent dispersal in a spatially structured population.

Habitat selection may have profound evolutionary consequences, but they strongly depend on the underlying preference mechanism, including genetically-determined, natal habitat and phenotype-dependent preferences. It is known that different mechanisms may operate at the same time, yet their relative contribution to population differentiation remains largely unexplored empirically mainly because of the difficulty of finding suitable study systems. Here, we investigate the role of early experience and genetic background in determining the outcome of settlement by pied flycatchers (Ficedula hypoleuca) breeding in two habitat patches between which dispersal and subsequent reproductive performance is influenced by phenotype (body size). For this, we conducted a cross-fostering experiment in a two-patch system: an oakwood and a conifer plantation separated by only 1 km. Experimental birds mostly returned to breed in the forest patch where they were raised, whether it was that of their genetic or their foster parents, indicating that decisions on where to settle are determined by individuals' experience in their natal site, rather than by their genetic background. Nevertheless, nearly a third (27.6 %) moved away from the rearing habitat and, as previously observed in unmanipulated individuals, dispersal between habitats was phenotype-dependent. Pied flycatchers breeding in the oak and the pine forests are differentiated by body size, and analyses of genetic variation at microsatellite loci now provide evidence of subtle genetic differentiation between the two populations. This suggests that phenotype-dependent dispersal may contribute to population structure despite the short distance and widespread exchange of birds between the study plots. Taken together, the current and previous findings that pied flycatchers do not always settle in the habitat to which they are best suited suggest that their strong tendency to return to the natal patch regardless of their body size

Recent studies indicate that C57BL/6J (B6) and FVB inbred mouse strains differ in post-oral fructose conditioning. This was demonstrated by their differential flavor conditioning response to intragastric fructose and their preference for fructose versus a non-nutritive sweetener. The present study extended this analysis to SWR and BALB/c inbred strains which are of interest because they both show robust flavor conditioning responses to fructose. In the first experiment, ad-libitum fed mice were given a series of 2-day, two-bottle preference tests between 8% fructose and a more preferred, but non-nutritive 0.1% sucralose +0.1% saccharin (S+S) solution (tests 1 & 4), and fructose or S+S versus water (tests 2 and 3). In test 1, SWR mice preferred S+S to fructose, and in tests 2 and 3, they preferred both sweeteners to water. In test 4, SWR mice switched their preference and consumed more fructose than S+S. In contrast, ad-libitum fed BALB/c mice strongly preferred S+S to fructose in both tests 1 and 4, although they preferred both sweeteners to water in tests 2 and 3. Food-restricted BALB/c mice also preferred the non-nutritive S+S to fructose in tests 1 and 4. The experience-induced fructose preference reversal observed in SWR, but not BALB/c mice indicates that fructose has a post-oral reinforcing effect in SWR mice as in FVB mice. Because B6 and FVB mice prefer glucose to fructose based on the post-oral actions of the two sugars, the second experiment compared the preferences of SWR and BALB/c mice for 8% glucose and fructose solutions. Ad-libitum fed and food-restricted SWR mice strongly preferred glucose to fructose. In contrast, ad-libitum fed BALB/c mice were indifferent to the sugars, perhaps because of their overall low intakes. Food-restricted BALB/c mice, however, strongly preferred glucose. These findings indicate that SWR and BALB/c mice differ in their preference response to the post-oral actions of fructose. Copyright © 2015 Elsevier Inc. All rights

Studies using sheep models indicate that the fetal mammary gland is sensitive to maternal nutrition during gestation; however, results have been inconsistent and do not identify critical feeding periods. This study aimed to clarify previous findings by partitioning the period of maternal nutritional manipulation into 2 stages: early and mid-to-late pregnancy. Sixty-six twin-born, twin-bearing ewes, born to dams that were fed either submaintenance, maintenance, or ad libitum during early pregnancy (d 21 to 50 of pregnancy; SmP21-50, MP21-50, or AdP21-50, respectively) and then either maintenance or ad libitum during mid-to-late pregnancy (d 50 to 140 of pregnancy; MP50-140 or AdP50-140, respectively) were milked once a week, starting from d 7 ± 1 postpartum, for 7 subsequent weeks to enable estimation of daily milk yield and composition. Their lambs were weighed weekly. Ewes born to dams fed MP21-50 tended to have greater accumulated milk (P = 0.10), fat (P = 0.07), and NE (P = 0.06) yields over 50 d compared with ewes born to dams fed SmP21-50 and AdP21-50. In contrast, ewes born to dams fed AdP50-140 tended to have greater accumulated milk (P = 0.10) and lactose (P = 0.09) yields compared with ewes born to dams fed MP50-140. Grandoffspring birth weights were unaffected by granddam nutrition during pregnancy. Ewes born to dams fed AdP21-50 weaned lighter lambs (P = 0.05) than ewes born to dams fed AmP21-50 and tended to wean lighter lambs (P = 0.07) than ewes born to dams fed MP21-50 whereas there were no differences between the weaning weights of lambs (P = 0.43) from ewes born to dams fed AdP50-140 and MP50-140. Maintenance nutrition of dams during early pregnancy appears to be associated with an improved lactation performance of ewe offspring. Higher levels of nutrition during mid-to-late pregnancy also appears to improve the first-lactation performance of ewe offspring. Interestingly, although grandoffspring birth weights were unaffected, weaning weight

1. Natal dispersal has the potential to affect most ecological and evolutionary processes. However, despite its importance, this complex ecological process still represents a significant gap in our understanding of animal ecology due to both the lack of empirical data and the intrinsic complexity of dispersal dynamics. 2. By studying natal dispersal of 74 radiotagged juvenile eagle owls Bubo bubo (Linnaeus), in both the wandering and the settlement phases, we empirically addressed the complex interactions by which individual phenotypic traits and external cues jointly shape individual heterogeneity through the different phases of dispersal, both at nightly and weekly temporal scales. 3. Owls in poorer physical conditions travelled shorter total distances during the wandering phase, describing straighter paths and moving slower, especially when crossing heterogeneous habitats. In general, the owls in worse condition started dispersal later and took longer times to find further settlement areas. Net distances were also sex biased, with females settling at further distances. Dispersing individuals did not seem to explore wandering and settlement areas by using a search image of their natal surroundings. Eagle owls showed a heterogeneous pattern of patch occupancy, where few patches were highly visited by different owls whereas the majority were visited by just one individual. During dispersal, the routes followed by owls were an intermediate solution between optimized and randomized ones. Finally, dispersal direction had a marked directionality, largely influenced by dominant winds. These results suggest an asymmetric and anisotropic dispersal pattern, where not only the number of patches but also their functions can affect population viability. 4. The combination of the information coming from the relationships among a large set of factors acting and integrating at different spatial and temporal scales, under the perspective of heterogeneous life histories, are a

Cape fur seal (Arctocephalus pusillus) pups spend the first weeks of life exclusively or mainly ashore. They are exposed to intense solar radiation and high temperatures for long time periods, which results in temperatures up to at least 80°C on their black natal coat. To test the hypothesis that the natal coat has a crucial function in coping with these extreme conditions, we investigated the insulating properties of the natal coat in six captive newborn Cape fur seals during the first 50 days after birth. The natal fur differs from the adult fur not only in colour, but also in density, structure, and water repellence. We measured temperature on the fur surface and within the fur, as well as skin and rectal temperature under varying environmental conditions, comparable to the species' habitat. Experiments were designed to not influence the spontaneous behaviour of the pups. Rectal temperature was constant as long as the pups stayed dry, even during long-lasting intense solar radiation for up to 3 h. Skin temperature remained close to rectal temperature as long as the fur was dry, while with wet fur, skin temperature was significantly reduced as well. Our results show that the natal coat provides an effective insulation against overheating. The severely reduced insulation of wet natal fur against cold supports the assumption that the natal fur is an adaptation to the pups' terrestrial phase of life.

Post-retrieval extinction in adolescence prevents return of juvenile fear

Traumatic experiences early in life can contribute to the development of mood and anxiety disorders that manifest during adolescence and young adulthood. In young rats exposed to acute fear or stress, alterations in neural development can lead to enduring behavioral abnormalities. Here, we used a modified extinction intervention (retrieval+extinction) during late adolescence (post-natal day 45 [p45]), in rats, to target auditory Pavlovian fear associations acquired as juveniles (p17 and p25). The effects of adolescent intervention were examined by assessing freezing as adults during both fear reacquisition and social transmission of fear from a cagemate. Rats underwent testing or training at three time points across development: juvenile (p17 or p25), adolescent (p45), and adult (p100). Retrieval+extinction during late adolescence prevented social reinstatement and recovery over time of fears initially acquired as juveniles (p17 and p25, respectively). Adolescence was the only time point tested here where retrieval+extinction prevented fear recall of associations acquired 20+ days earlier. PMID:27634147

In 2011, the Health Emergency Management Bureau (HEMB) created the Surveillance for Post Extreme Emergencies and Disasters (SPEED), a real-time syndromic surveillance system that allows the early detection and monitoring of post-disaster disease trends. SPEED can assist health leaders in making informed decisions on health systems affected by disasters. There is a need for further validation of current concepts in post-disaster disease patterns in respect to actual field data. This study aims to evaluate the temporal post-disaster patterns of selected diseases after a flood, an earthquake, and a typhoon in the Philippines in 2013. We analyzed the 21 syndromes provided by SPEED both separately and grouped into injuries, communicable diseases, and non-communicable diseases (NCDs) by calculating daily post-disaster consultation rates for up to 150 days post-disaster. These were compared over time and juxtaposed according to the type of disaster. Communicable diseases were found to be the predominant syndrome group in all three disaster types. The top six syndromes found were: acute respiratory infections, open wounds, bruises and burns, high blood pressure, skin disease, fever, and acute watery diarrhea. Overall, the results aligned with the country's morbidity profile. Within 2 months, the clear gradation of increasing syndrome rates reflected the severity (floodnutrition, and common health services. Most post-disaster syndromes may be addressed by prevention, early diagnosis, and early treatment. Health needs differ in response and recovery phases.

Many women of reproductive age from developing countries have poor nutritional status, and the prevalence of depression during pregnancy is high. The objective of the present study was to assess the prevalence of antenatal depressive symptoms in early pregnancy, and to identify the demographic and nutritional factors associated with these symptoms in a sample of urban South Indian pregnant women. This cross-sectional study was the baseline assessment of a prospective randomized controlled trial of vitamin B12 supplementation in urban pregnant south Indian women between the ages of 18 and 40 years ( www.clinicaltrials.gov : NCT00641862). 365 women in their first trimester of pregnancy were screened for depressive symptoms at an urban clinic in Karnataka, South India, using the Kessler Psychological Distress Scale (K-10). Nutritional, clinical and biochemical factors were also assessed. Mean (SD) age of the cohort was 22.6 (3.7) years and mean (SD) BMI was 20.4 (3.3) kg/m(2). 121 (33 %) of the women in the 1st trimester had symptoms consistent with depression (K-10 score >6). In multivariate log binomial regression analysis, presence of antenatal depressive symptoms in the first trimester were positively associated with vomiting, prevalence ratio (PR) = 1.54 (95 % CI 1.10, 2.16) and negatively with anemia, PR = 0.67 (95 % CI 0.47, 0.96). Nutrient intakes, serum vitamin B12, methylmalonic acid, homocysteine and red cell folate levels were not associated with measures of depression. Antenatal depressive symptoms in early pregnancy are highly prevalent in urban Indian women and are more common in women with vomiting and without anemia. In this cross-sectional data, blood concentrations of vitamin B12 and folate were not associated with depressive symptoms. The relationship between nutritional status and depressive symptoms may require larger and longitudinal studies.

Better Living Health and Community Services developed a 12-week community-based nutrition information series (NIS) for people aged 55 or older. The purpose of this feasibility study was to describe briefly the process of developing and implementing the 12-week NIS and to identify the practicality and plausibility of the program in terms of its process and content attributes, using Thorncliffe Park community as the test site. A pre- and post-test design was used to identify changes in participants' perception of their nutritional and overall well-being. Twenty-four participants who completed at least four sessions participated in the post-evaluation follow-up. Only participants' perception of their eating habits demonstrated a significant, positive improvement (t24=2.1, P<0.05). The results suggest that the NIS has the potential to promote the health and well-being of community-living seniors. The development and implementation of the NIS provided considerations for program practicality. However, additional work is needed to examine the plausibility of the program in meeting its stated objective to promote awareness of nutrition as an important concept for healthy aging. Community-practising dietitians are instrumental in providing credible nutrition information to facilitate healthy eating in older Canadians.

Rocket salad (Diplotaxis tenuifolia; wild rocket) is an important component of ready to eat salads providing a distinct peppery flavour and containing nutritionally relevant compounds. Quality deteriorates during post-harvest, in relation to time and storage temperature amongst other factors. Volatile organic compounds (VOCs) are easily measurable from rocket leaves and may provide useful quality indicators for e.g. changes in isothiocyanates derived from nutritionally important glucosinolates. VOC profiles discriminated storage temperatures (0, 5 and 10°C) and times (over 14days). More specifically, concentrations of aldehydes and isothiocyanates decreased with time paralleling a fall in vitamin C and a reduction in sensorial quality at the two higher temperatures. Sulphur containing compounds rise at later time-points and at higher temperatures coincident with an increase in microbial titre, mirroring a further drop in sensorial quality thus indicating their contribution to off-odours.

Many patients leave hospital in poor nutritional states, yet little is known about the post-discharge nutrition care in which patients are engaged. This study describes the nutrition-care activities 30-days post-discharge reported by patients and what covariates are associated with these activities. Quasi-randomly selected patients recruited from 5 medical units across Canada (n = 513) consented to 30-days post-discharge data collection with 48.5% (n = 249) completing the telephone interview. Use of nutrition care post-discharge was reported and bivariate analysis completed with relevant covariates for the two most frequently reported activities, following recommendations post-discharge or use of oral nutritional supplements (ONS). A total of 42% (n = 110) received nutrition recommendations at hospital discharge, with 65% (n = 71/110) of these participants following those recommendations; 26.5% (n = 66) were taking ONS after hospitalization. Participants who followed recommendations were more likely to report following a special diet (p = 0.002), different from before their hospitalization (p = 0.008), compared to those who received recommendations, but reported not following them. Patients taking ONS were more likely to be at nutrition risk (p < 0.0001), malnourished (p = 0.0006), taking ONS in hospital (p = 0.01), had a lower HGS (p = 0.0013; males only), and less likely to believe they were eating enough to meet their body’s needs (p = 0.005). This analysis provides new insights on nutrition-care post-discharge. PMID:29361696

The lack of benefit from randomised controlled trials has resulted in significant controversy regarding the role of nutrition during critical illness in terms of long-term recovery and outcome. Although methodological caveats with a failure to adequately appreciate biological mechanisms may explain these disappointing results, it must be acknowledged that nutritional support during early critical illness, when considered alone, may have limited long-term functional impact.This narrative review focuses specifically on recent clinical trials and evaluates the impact of nutrition during critical illness on long-term physical and functional recovery.Specific focus on the trial design and methodological limitations has been considered in detail. Limitations include delivery of caloric and protein targets, patient heterogeneity, short duration of intervention, inappropriate clinical outcomes and a disregard for baseline nutritional status and nutritional intake in the post-ICU period.With survivorship at the forefront of critical care research, it is imperative that nutrition studies carefully consider biological mechanisms and trial design because these factors can strongly influence outcomes, in particular long-term physical and functional outcome. Failure to do so may lead to inconclusive clinical trials and consequent rejection of the potentially beneficial effects of nutrition interventions during critical illness.

Fetal and neo-natal maxillary ontogeny in extant humans and the utility of prenatal maxillary morphology in predicting ancestral affiliation

PubMed Central

Objectives The midface of extant H. sapiens is known to undergo shape changes through fetal and neo-natal ontogeny; however, little work has been done to quantify these shape changes. Further, while midfacial traits which vary in frequency between populations of extant humans are presumed to develop prenatally, patterns of population-specific variation maxillary shape across ontogeny are not well documented. Only one study of fetal ontogeny which included specific discussion of the midface has taken a 3D geometric morphometric approach, and that study was limited to one population (Japanese). The present research project seeks to augment our understanding of fetal maxillary growth patterns, most especially in terms of intraspecific variation. Materials and Methods Three-dimensional coordinate landmark data were collected on the right maxillae of 102 fetal and neo-natal individuals from three groups (Euro-American, African-American, “Mixed Ancestry”). Results Shape changes were seen mainly in the lateral wall of the piriform aperture, the anterior nasal spine, and the subnasal alveolar region. The greatest difference across age groups (2nd Trimester, 3rd Trimester, Neonates) was between the second and third trimester. Euro-Americans and African-Americans clustered by population and differences in midfacial morphology related to ancestry could be discerned as early as the second trimester (p=0.002), indicating that population variation in maxillary morphology appears very early in ontogeny. Discussion The midface is a critical region of the skull for assessing ancestry and these results indicate that maxillary morphology may be useful for estimating ancestry for prenatal individuals as young as the second trimester.

After renal transplantation recovery in nutritional status occurs during the first year. We assessed the changes in nutritional status after transplantation in 145 transplant recipients (94 males, 51 females). Patients were evaluated immediately after renal transplant (baseline data) and at 6 months' follow-up. Analysis included body mass index (BMI), body composition (skin fold and arm circumference), and estimated body composition (calculated percent of fat, arm circumference, arm muscle circumference, and arm muscle area). Other data obtained from medical records included renal function (MDRD) serum albumin and lipid profile. At baseline evaluation (21 ± 15 days posttransplant), mean BMI was 23.9 ± 3.9 kg/m(2), serum albumin was 3.7 ± 0.7 g/dL, and lipid profile showed (cholesterol 158.5 ± 52.7 mg% and triglycerides 135.9 ± 91.8 mg%. Body composition analysis showed better adaptation of muscle mass in females [AC (91 ± 10.2 × 98 ± 14.6; male × female, P < .05) arm muscle circumference (92.6 ± 1.4 × 102.3% ± 2.9%, male × female, P < .05) and arm muscle area (87.1 ± 22.3 × 105.5% ± 25.9%, male × female, P < .05)]. Body fat was above the recommended levels in 80% of patients, especially females. After 6 months we divided the groups according to BMI, observing better renal function in the normal weight group compared with obese subjects (60 ± 17.2 × 39.5 ± 19.8 mL/min MDRD, P < .05), despite comparable estimated glomerular filtration rate at baseline. The nutritional assessment of patients with end-stage renal disease early after renal transplantation, showed inadequate body composition, with increased fat and reduced lean body mass. The lower glomerular filtration rate after 6 months may be attributed to relatively inadequate renal mass or to obesity-induced hyperfiltration. Copyright © 2012 Elsevier Inc. All rights reserved.

The primary aim of this case study was to explore the behavioural changes of a paediatric patient in post-traumatic amnesia (PTA) during a music therapy session. A secondary objective was to measure the effect of the music therapy intervention on agitation. Video data from pre, during and post-music therapy sessions were collected and analysed using video micro-analysis and the Agitated Behaviour Scale. The participant displayed four discrete categories of behaviours: Neutral, Acceptance, Recruitment and Rejection. Further analysis revealed brief but consistent and repeated periods of awareness and responsiveness to the live singing of familiar songs, which were classified as Islands of Awareness. Song offered an Environment of Potential to maximise these periods of emerging consciousness. The quantitative data analysis yielded inconclusive results in determining if music therapy was effective in reducing agitation during and immediately post the music therapy sessions. The process of micro-analysis illuminated four discrete participant behaviours not apparent in the immediate clinical setting. The results of this case suggest that the use of familiar song as a music therapy intervention may harness early patient responsiveness to foster cognitive rehabilitation in the early acute phase post-TBI.

Nutritional support is critical for preterm infants in the neonatal intensive care unit (NICU). A multidisciplinary nutritional support team (NST) that focuses on providing optimal and individualized nutrition care could be helpful. We conducted a thorough evaluation of clinical and nutritional outcomes in a tertiary NICU following the implementation of an NST. This study used a retrospective approach with historical comparisons. Preterm neonates < 30 weeks gestational age or weighing < 1250 g were enrolled. Clinical and nutritional outcomes were compared before and after the establishment of the NST. Medical records were reviewed, and clinical and nutritional outcomes were compared between the two groups. In total, 107 patients from the pre-NST period and 122 patients from the post-NST period were included. The cumulative energy delivery during the first week of life improved during the post-NST period (350.17 vs. 408.62 kcal/kg, p < 0.001). The cumulative protein and lipid deliveries also significantly increased. The time required to reach full enteric feedings decreased during the post-NST period (6.4 ± 5.8 vs. 4.7 ± 5.1 days, p = 0.016). Changes of Z-score in weight from admission to discharge exhibited more favorable results in the post-NST period (-1.13 ± 0.99 vs.-0.91 ± 0.74, p = 0.055), and the length of ICU stay significantly decreased in the post-NST period (81.7 ± 36.6 vs. 72.2 ± 32.9 days, p = 0.040). NST intervention in the NICU resulted in significant improvements in the provision of nutrition to preterm infants in the first week of life. There were also favorable clinical outcomes, such as increased weight gain and reduced length of ICU stay. Evaluable data remain sparse in the NICU setting with premature neonatal populations; therefore, the successful outcomes identified in this study may provide support for NST practices.

Observational studies show consistent links between early-life nutritional exposures as important risk factors for the development of asthma, allergy, and obesity. Reliance on increasing use of dietary supplementation and fortification (eg, with folate) to compensate for increased consumption of processed foods is also influencing immune and metabolic outcomes. Epigenetics is providing substantial advances in understanding how early-life nutritional exposures can effect disease development. This article summarizes current evidence linking the influence of early-life nutritional exposures on epigenetic regulation with a focus on the disease outcomes of asthma, allergy, and obesity.

nutritional intake and status of soccer players has attracted not much research attention. Many soccer players follow an inadequate nutritional intake and have a poor nutritional status. This is relevant in youngsters soccer players, in order to improve performance and promote healthy dietary practices. analyze anthropometric characterizes, evaluate nutritional intake and status, dietary habits and pre- and post-exercise meals in elite teenagers soccer players. seventy-two young male soccer players (15-20 years) from four junior teams of a soccer Club from the Mexican National Soccer League were measured for height, seat height, weight, 6 skinfolds, 6 diameters and 7 circumferences, height-for-age and BMI-for-age values. Skin, adipose, muscle, bone and residual tissue masses were calculated with the Ross and Kerr equation. Resting energy expenditure and intake was also measured. Daily dietary intake was self-recorded for 4 consecutive days (excluding the match day) using a digital food-weighing scale and a food record questionnaire. Dietary analysis was performed using the NutriBase 7 Clinical software. Several biochemical values were determined. One-way analysis of variance (ANOVA) and post hoc testing was performed using t-tests with a Bonferroni correction. all soccer players were within the normal range values for anthropometric parameters studies, when compared with other adolescent elite soccer teams. Values of plasma glucose, urea, creatinine, uric acid, lipid profile and total proteins were within normal range for young adult population, although albumin levels were high. Moreover, 14% and 20% of soccer players presented hyperuricemia and elevated total cholesterol levels respectively. Energy expenditure and intake were within normal range for all teenager elite soccer players. However, two teams shower significant lower intakes than demands. All macronutrient intakes were within recommendations, except protein that was higher. Micronutrient intake exceeded

Purpose. Because of its role in cell cycle regulation and apoptosis, p53 may be involved in maintaining the post-mitotic state of the adult eye. To shed light on the role of p53 in retinal development and maintenance, this study investigated the pattern of expression of p53, its family members, and its regulators during the development of the mouse eye. Methods. Relative quantitative real-time PCR (qRT-PCR) was used to determine the steady-state levels of target transcripts in RNA extracted from wild-type mouse whole eyes or retinas between embryonic day (E) 15 and post-natal day (P) 30. Immunoblotting was used to compare the steady-state levels of the protein to that of the transcript. Results. Transcript and protein levels for p53 in the eye were highest at E17 and E18, respectively. However, both p53 transcript and protein levels dropped precipitously thereafter, and no protein was detected on immunoblots after P3. Expression patterns of p63, p73, Mdm2, Mdm4, and Yy1 did not follow that of p53. Immunohistochemistry analysis of the developing eye showed that both p53 and Mdm2 are abundantly expressed at E18 in all layers of the retinal neuroblast. Conclusions. Downregulation of p53 in the post-mitotic retina suggests that, although p53 may be involved in ocular and retinal development, it may play a minimal role in healthy adult retinal function.

Asymptomatic bacteriuria in pregnancy is associated with potential urinary and obstetric complications. However the prevalence aetiology and antimicrobial sensitivity patterns of asymptomatic bacteriurea among women attending ante-natal care in our Hospital is not known. To determine the prevalence and identify the aetiological agents associated with asymptomatic bacteriurea in antenatal mothers in Mulago Hospital. We also intended to determine the anti-microbial sensitivity patterns of the common uropathogen in this population We performed culture and anti-microbial sensitivity tests on urine samples from 218 consecutive ante-natal mothers in Mulago Hospital. All participants did not have any clinical symptoms attributable to urinary tract infection. Twenty nine (13.3%) of the samples had significant bacterial growth and E.coli was the commonest isolate (51.2%). There was a high level (20-62%) of anti-bacterial resistance to the commonly used antibiotics. Asymptomatic bacteriuria is common among ante-natal mothers in Mulago. E. Coli that is resistant to the most commonly used antibiotics is the commonest isolate."

Early post-fire succession in California chaparral: changes in diversity, density, cover, and biomass

Guo, Q.

2001-01-01

For four consecutive years, following the fires in November 1993, temporal variations in species richness, cover and biomass of component plant groups in early post-fire chaparral succession were monitored on different aspects at the Stunt Ranch Santa Monica Mountains Reserve, southern California. Plant groups were categorized based on growth form, life form, ability to fix nitrogen, geographic origin and regeneration strategies. North-facing slopes exhibited higher species richness, higher species turnover rate over time and faster vegetation recovery in terms of biomass accumulation and return to pre-fire species composition. This was probably due to higher species richness and biomass of nitrogen-fixing species found on north-facing slopes in comparison to south-facing slopes. On both north- and south-facing slopes, annuals had the highest species turnover rate, followed by herbaceous perennials and shrubs. In the first four post-fire years, annual species were the largest floristic group, but herbaceous perennials and shrubs were the major contributors to community biomass. Nitrogen-fixing species and exotics contributed significantly to early post-fire community structure. Although the general trends in post-fire succession are clear in terms of temporal changes in the relative proportions of different plant groups, environmental variation and the nature of plant life histories of component species, especially dominant species, could alter such trends significantly.
