[PMID: 27567176 DOI: 10.1016/j.jjcc.2016.05.009] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2016] [Revised: 05/04/2016] [Accepted: 05/20/2016] [Indexed: 11/16/2022]
Abstract
BACKGROUND Although the effect of overweight or obesity on clinical outcomes in patients with acute myocardial infarction (MI) has been reported, the effect of undernutrition is not as well understood. Therefore, we investigated whether acute MI patients frequently present with undernutrition, and whether this influences poor clinical outcomes. METHODS AND RESULTS Using the Korea Acute Myocardial Infarction Registry database, we screened initial data on acute MI patients admitted within 48h of symptom onset to a tertiary university hospital between November 1, 2011 and May 31, 2015. We then assessed nutritional status at admission, using the Geriatric Nutritional Risk Index (GNRI). Of a total of 2251 patients, there were 1585 (70.4%) men, and mean age was 65.0±12.8 years. Based on GNRI score, undernutrition at admission was present in 409 (18.2%) patients. Multiple logistic regression analysis found undernutrition to be an independent factor influencing post-MI complications [odds ratio (OR), 2.13; 95% confidence interval (CI), 1.61-2.84; p<0.001], after adjusting for age, sex, hypertension, diabetes, hyperlipidemia, previous stroke, smoking, diagnosis, number of involved vessel lesions, Killip class, atrial fibrillation, baseline blood pressure, hemoglobin, creatine kinase-MB, creatinine, performance of percutaneous coronary intervention, reperfusion time, recanalization, and use of antithrombotics. Undernutrition was also an important factor influencing in-hospital death (OR, 2.48; 95% CI, 1.55-3.95; p<0.001), after adjusting for all potential factors by univariate analysis. CONCLUSIONS Nutritional status is a significant prognostic factor in clinical outcomes after MI during hospitalization. Therefore, nutritional assessment and intervention, especially for undernourished MI patients, should be considered.

Undernutrition and associated factors among adults living with Human Immune Deficiency Virus in Dembia District, northwest Ethiopia: an institution based cross-sectional study. ACTA ACUST UNITED AC 2016; 74:33. [PMID: 27468351 PMCID: PMC4962389 DOI: 10.1186/s13690-016-0143-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2016] [Accepted: 05/20/2016] [Indexed: 11/25/2022]
Abstract
Background Appropriate dietary intake determines the disease progression and success of Anti-Retroviral Therapy (ART). Undernutrition unacceptably increases the risk of mortality among adults living with Human Immune Deficiency Virus (HIV). However in resource limited settings including Ethiopia, many of HIV positive clients lack access to sufficient quantities of nutritious food. There is limited evidences showing the magnitude of undernutrition in this segment of the community, particularly in the rural residents. Therefore, this study aimed to assess undernutrition and associated factors among HIV positive adults attending ART clinic in Dembia District. Methods An institution based cross-sectional study was conducted in Dembia District from October 1 to 30, 2015. Systematic random sampling technique was used to recruit the study subjects. The anthropometric measurement, Body Mass Index, was computed to determine the nutritional status of the study participants. In order to identify factors associated with undernutrition a multivariable logistic regression analysis was employed. The Adjusted Odds Ratio (AOR) with 95 % Confidence Interval (CI) was calculated to show the strength of association. In multivariable analysis, variables with a P-value of <0.05 were considered as statistically significant. Results Of the study participants, about 23.2 % [95 % CI: 19.2, 27.2 %] were undernourished in Dembia District. The result of adjusted analysis revealed that, the odds of undernutrition was higher among adults whose age ranged between 18-29 years [AOR = 2.50, 95 % CI: 1.10, 5.69], who had a Cluster of Differentiation (CD)4 count less than 200 cells/mm3 [AOR = 6.21, 95 % CI: 2.97, 12.98), were widowed [AOR = 2.18, 95 % CI: 1.08,4.40), and anemic [AOR = 3.17, 95 % CI: 1.70, 5.92]. Conclusions The prevalence of undernutrition among HIV positive adults was higher in the study area. Furthermore, being in the age range of 18-29 years, widowed, anemic, and having a CD4 count of less than 200 cells/mm3 were positively associated with undernutrition. Therefore, efforts should be strengthened to mitigate the higher burden of undernutrition by considering the identified determinants.

Abstract
BACKGROUND Worldwide we are facing a serious demographic challenge due to the dramatic growth of the population over 60 years. It is expected that the proportion of this population will nearly double from 12 to 22 %, between 2015 and 2050. This demographic shift comes with major health and socio-economic concerns. Nutrition is a fundamental determinant of both health and disease and its role in extending a healthy lifespan is the object of considerable research. Notably, malnutrition is one of the main threats to health and quality of life among the elderly. Therefore, knowledge about nutritional status among the elderly is essential for the promotion and maintenance of healthy ageing and to support the development of health protection policies and equity in elderly health care. METHODS This is a nationwide nutrition survey of the Portuguese population over 65 years old, with data collection through face-to-face interviews. A representative and random sample of community dwelling elderly and nursing homes residents will be obtained by multistage sampling stratified per main Portuguese regions, sex and age groups. Minimum sample size was estimated to be 2077 elderly (979 in the community and 1098 in nursing homes). Data will be collected on food habits and eating patterns, nutritional status, food insecurity, lifestyle, self-rated general health status and self-reported diseases, functionality, loneliness, cognitive function, emotional status and demographic and socio-economic characterization. DISCUSSION This is the first national survey to evaluate the prevalence of nutritional risk and malnutrition of the Portuguese population above 65 years old, including those living in nursing homes. It will allow the identification of population subgroups of elderly with increased odds of malnutrition and nutritional risk. In addition, this survey will contribute to the identification of psychosocial and clinical predictors of malnutrition among elderly, which is an important risk factor for other devastating medical conditions.

Abstract
Background Undernutrition remains the major public health concern in Ethiopia and continues as the underlying cause of child mortality. However, there is a scarcity of information on the magnitude and determinant factors of undernutrition. Therefore, this study aimed to assess the prevalence of undernutrition and associated factors among children aged 6–59 months in East Belesa District, northwest Ethiopia. Methods A community-based cross-sectional study was conducted from April to May, 2014. A multistage stratified sampling technique was used to select 633 study participants. A structured interviewer-administered questionnaire was used to collect data. In order to identify factors associated with undernutrition (stunting and wasting) a multivariate logistic regression analysis was employed. The Adjusted Odds Ratio (AOR) with a 95 % Confidence Interval (CI) was computed to show the strength of the association. In the multivariate analysis, variables with a p-value of <0.05 were considered as statistically significant. Results In this study, about 57.7 and 16 % of the children were stunted and wasted, respectively. The odds of stunting were higher in children born to mothers who gave their first birth before 15 years of age (AOR = 2.4; 95 % CI: 1.19, 5.09) and gave prelacteal feeding to their child (AOR = 1.83; 95 % CI: 1.28, 2.61). However, lower odds of stunting were observed among children aged 36–47 months (AOR = 0.41; 95 % CI: 0.22, 0.78) and had higher family monthly income, Et. Br. 750–1000, (AOR = 0.61; 95 % CI: 0.39, 0.92). Moreover, the odds of wasting were higher among children who received butter as prelacteal food (AOR = 2.32; 95 % CI:1.82, 5.31). Conclusion Child undernutrition is a critical public health problem in the study area. Advanced age of children (36–47 months) and higher family monthly income were inversely associated with stunting. However, higher odds of stunting were observed among children whose mothers delivered their first child before 15 years of age, and gave their children prelacteal feeding. Thus, delaying the first pregnancy and reducing prelacteal feeding is of a paramount significance in reducing the burden of undernutrition.

Abstract
Screening for undernutrition is highly important and may reduce morbidity and mortality. The Minimal Eating Observation and Nutrition Form Version II (MEONF-II) is a nutritional screening tool specifically developed for use by nurses. The authors describe the translation, performance and appropriateness of MEONF-II for the UK. Following translation from Swedish to British English, the user-friendliness and appropriateness of the British MEONF-II was tested by 29 registered nurses and final-year student nurses on 266 hospital inpatients. The new British MEONF-II was perceived as highly user-friendly and appropriate. Assessors found MEONF-II to compare favourably with other similar tools in terms of preference, usefulness and helpfulness in providing good nutritional care. Dependency in activities and poorer subjective health were associated with a higher risk of undernutrition. These findings support the appropriateness of the British MEONF-II version and suggest it may act as a user-friendly facilitator for good nutritional nursing care.

Abstract
BACKGROUND Brain development in early childhood is a key determinant of later cognition, social achievement and educational success. Head circumference (HC) measurements are a simple method to assess brain growth, yet reports of these measurements are uncommon in nutritional surveys of undernourished children. OBJECTIVE To evaluate HC measurements in a population of rural Nepali children and relate these measurements to demographics, health and diet. METHODS An observational study of head growth was nested within a longitudinal evaluation of a livestock-based agricultural intervention in rural Nepal. Between 538 and 689 children (aged 6 months to 8 years) were measured (height, weight, HC) at each of six survey visits. A total of 3652 HC measurements were obtained. Results were converted to Z-scores (WHO Anthro). RESULTS Mean head circumference Z-scores (HCZ) diminished progressively over the first 4 years of life; a decline of 30% occurred between 3 and 4 years of age (-1.73 to -2.45, P < 0.0001). Overall, 56% of HCZ were <-2. Gender-adjusted HCZ (but not other measurements) were significantly lower for girls than boys [mean (SD) -2.31 (1.0) vs -1.99 (0.094), P < 0.0001]; girls more often had microcephaly (61% vs 50%, P < 0.0001). For children <3 years of age, HCZ were better in those who had eaten two or more animal-source foods (ASFs) within the previous 24 h [-1.69 (.05) vs -2.08 (0.10), P = 0.001] than in those who had eaten none or only one; HCZ correlated with the number of ASFs consumed (P < 0.001). Regression analyses demonstrated that the main determinants of HCZ were age, weight-for-age Z-scores (WAZ) and gender; 43% of the variance in HCZ in younger children was explained by WAZ and ASF consumption. CONCLUSION HCs reflect brain size in young children; brain size is linked to cognitive function. Poor head growth represents another facet of the 'silent emergency' of child undernutrition. Routine HCZ assessments may contribute to better understanding of the links between poverty and cognitive development.

Abstract
Mitochondrial bioenergetics dysfunction has been postulated as an important mechanism associated to a number of cardiovascular diseases in adulthood. One of the hypotheses is that this is caused by the metabolic challenge generated by the mismatch between prenatal predicted and postnatal reality. Perinatal low-protein diet produces several effects that are manifested in the adult animal, including altered sympathetic tone, increased arterial blood pressure and oxidative stress in the brainstem. The majority of the studies related to nutritional programming postulates that the increased risk levels for non-communicable diseases are associated with the incompatibility between prenatal and postnatal environment. However, little is known about the immediate effects of maternal protein restriction on the offspring's brainstem. The present study aimed to test the hypothesis that a maternal low-protein diet causes tissue damage immediately after exposure to the nutritional insult that can be assessed in the brainstem of weaned offspring. In this regard, a series of assays was conducted to measure the mitochondrial bioenergetics and oxidative stress biomarkers in the brainstem, which is the brain structure responsible for the autonomic cardiovascular control. Pregnant Wistar rats were fed ad libitum with normoprotein (NP; 17% casein) or low-protein (LP; 8% casein) diet throughout pregnancy and lactation periods. At weaning, the male offsprings were euthanized and the brainstem was quickly removed to assess the mitochondria function, reactive oxygen species (ROS) production, mitochondrial membrane electric potential (ΔΨm), oxidative biomarkers, antioxidant defense and redox status. Our data demonstrated that perinatal LP diet induces an immediate mitochondrial dysfunction. Furthermore, the protein restriction induced a marked increase in ROS production, with a decrease in antioxidant defense and redox status. Altogether, our findings suggest that LP-fed animals may be at a higher risk for oxidative metabolism impairment throughout life than NP-fed rats, due to the immediate disruption of the mitochondrial bioenergetics and oxidative status caused by the LP diet.

Abstract
OBJECTIVE The present study aimed to identify the role of mother's education in the nutritional status of children aged 2-5 years in Serbia. DESIGN Nationally representative population-based study. Age- and gender-specific BMI percentiles of children were analysed. In accordance with the WHO growth reference, children with BMI less than the 5th percentile were considered undernourished. Logistic regression was used to calculate the association between mother's education and other socio-economic determinants as possible confounders. SETTING UNICEF's fourth Multiple Indicator Cluster Survey, conducted in both Roma and non-Roma settlements in Serbia. SUBJECTS Children (n 2603) aged 2-5 years (mean age 3·05 years). RESULTS Less than 5 % of children aged 2-5 years were undernourished. There were significantly more undernourished children among the Roma population, in the capital of Serbia and among those whose mothers were less educated. There were statistically significant differences according to mother's education in all socio-economic characteristics (ethnicity, area, region of living and wealth index). Mother's level of education proved to be the most important factor for child's nutritional status; place of living (region) was also associated. CONCLUSIONS Mother's education is the most significant predictor of children's undernutrition. It confirms that investment in females' education will bring benefits and progress not only for women and their children, but also for society as a whole.

Abstract
Disease Related Malnutrition (DRM) is highly prevalent in Spanish hospitals. WHO estimates that 20-40% of health-associated expenses are lost due to inefficiency. Demonstration that DRM is a component of inefficiency and hiring a specialist physician for its detection and treatment is cost-effective. MATERIAL AND METHODS Comparison between nutritional diagnosis and procedures detected and encoded at discharge using McNemar test. Recoding of 162 discharge reports including nutritional diagnoses and procedures. Determine changes on Case-Mix Index (IC), cost of procedure and cost procedure/DRG index. Comparison using T-student paired test. RESULTS Only 10 of 162 diagnoses of malnutrition were coded in delivery statements (p < 0.001). After right codification, IC increased in 103,3 DRG points (p < 0.001). Consequently, procedure cost/DRG index was reduced in 978.81 € (p < 0.001). CONCLUSIONS DRM is underdiagnosed in our hospital. DRM and nutritional procedures detection by a doctor specialist in clinical nutrition led to a reduction in cost procedure/DRG index of 16.8% of officially established by the Health System. Loss of 16.8% of health expenses, estimated in 424.785,15 € was described. Proper codification would have justified 343.291,2 € reimbursement just for nutritional diagnoses and processes. Both expenses were lost due to system's inefficiency. Those amounts are much higher than cost associated of hiring a specialist in clinical nutrition.

Abstract
BACKGROUND/AIM Undernutrition affects about 40% of patients in hospitals. Ordinary food is recommended as the first choice to prevent and correct undernutrition. Meanwhile, sufficient intake, especially regarding protein, is difficult to reach, in patients at nutritional risk. The aim of this study was to improve protein intake at breakfast to at least 20% of total daily requirement or at least 20 g. METHODS A protein rich breakfast including 20 g of protein was served in the departments of heart and lung surgery and vascular surgery for three months. Nutrition intake was registered before and after intervention. RESULTS Food intake records were collected from 32 and 30 patients respectively, mean age 69 (SD 8) years. At breakfast, protein intake was improved from 14% of individual requirements to 22% (p<0.001) and energy intake was improved from 18% to 25% (p=0.01). Total amount of protein intake for breakfast was increased from 14 g to 20 g (p<0.002). Total daily protein intake increased from 64% to 77% (p=0.05) and total energy intake from 76% to 99% (p<0.01) of requirements. CONCLUSION Protein and energy intake for surgical patients at breakfast as well as total daily intake was significantly increased to meet recommended average level for minimum individually measured requirements.

Abstract
OBJECTIVE The present analysis aimed to observe nutritional impacts among children <5 years of age by mother's engagement in paid employment. DESIGN Between 1996 and 2012, 21 443 children <5 years of age with diarrhoea attended the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), Dhaka Hospital. They were enrolled in the hospital-based Diarrhoeal Disease Surveillance System and their relevant information was extracted from the electronic database. SETTING The icddr,b, Bangladesh. SUBJECTS The analytic sample was 19 597 children aged <5 years who had a mother aged ≤35 years with or without engagement in paid employment. RESULTS Eleven per cent of the mothers (n 2051) were currently engaged in paid employment on behalf of the family. Univariate analysis showed that children with mothers engaged in paid employment had a 1·14 times higher risk of being undernourished, a 1·20 times of higher risk of being stunted, a 1·21 times higher risk of being wasted and a 1·31 times higher risk of being underweight (risk ratios) than were children with mothers not likewise engaged. Multivariate analysis showed that such associations remained significant for stunting (1·08; 95 % CI 1·00, 1·16), wasting (1·15; 95 % CI 1·06, 1·25) and underweight (1·09; 95 % CI 1·02, 1·17) after controlling for covariates. CONCLUSIONS Mothers' engagement in income-generating employment was associated with undernutrition in children <5 years of age in urban Bangladesh.

Abstract
Both undernutrition and hypoxia exert a negative influence on both growth pattern and bone mechanical properties in developing rats. The present study explored the effects of chronic food restriction on both variables in growing rats exposed to simulated high-altitude hypoxia. Male rats (n 80) aged 28 d were divided into normoxic (Nx) and hypoxic (Hx) groups. Hx rats were exposed to hypobaric air (380 mmHg) in decompression chambers. At T0, Nx and Hx rats were subdivided into four equal subgroups: normoxic control and hypoxic controls, and normoxic growth-restricted and hypoxic growth-restricted received 80 % of the amount of food consumed freely by their respective controls for a 4-week period. Half of these animals were studied at the end of this period (T4). The remaining rats in each group continued under the same environmental conditions, but food was offered ad libitum to explore the type of catch-up growth during 8 weeks. Structural bone properties (strength and stiffness) were evaluated in the right femur midshaft by the mechanical three-point bending test; geometric properties (length, cross-sectional area, cortical mass, bending cross-sectional moment of inertia) and intrinsic properties of the bone tissue (elastic modulus) were measured or derived from appropriate equations. Bone mineralisation was assessed by ash measurement of the left femur. These data indicate that the growth-retarded effects of diminished food intake, induced either by food restriction or hypoxia-related inhibition of appetite, generated the formation of corresponding smaller bones in which subnormal structural and geometric properties were observed. However, they seemed to be appropriate to the body mass of the animals and suggest, therefore, that the bones were not osteopenic. When food restriction was imposed in Hx rats, the combined effects of both variables were additive, inducing a further reduction of bone mass and bone load-carrying capacity. In all cases, the mechanical properties of the mineralised tissue were unaffected. This and the capacity of the treated bones to undergone complete catch-up growth with full restoration of the biomechanical properties suggest that undernutrition, under either Nx or Hx conditions, does not affect bone behaviour because it remains appropriate to its mechanical functions.

Abstract
OBJECTIVE Humans and animals exposed to undernutrition (UN) during development often experience accelerated "catch-up" growth when food supplies are plentiful. Little is known about the mechanisms regulating early growth rates. We previously reported that actions of leptin and presynaptic inputs to orexigenic NPY/AgRP/GABA (NAG) neurons in the arcuate nucleus of the hypothalamus are almost exclusively excitatory during the lactation period, since neuronal and humoral inhibitory systems do not develop until after weaning. Moreover, we identified a critical step that regulates the maturation of electrophysiological responses of NAG neurons at weaning - the onset of genes encoding ATP-dependent potassium (KATP) channel subunits. We explored the possibility that UN promotes subsequent catch-up growth, in part, by delaying the maturation of negative feedback systems to neuronal circuits driving food intake. METHODS We used the large litter (LL) size model to study the impacts of postnatal UN followed by catch-up growth. We evaluated the maturation of presynaptic and postsynaptic inhibitory systems in NAG neurons using a combination of electrophysiological and molecular criteria, in conjunction with leptin's ability to suppress fasting-induced hyperphagia. RESULTS The onset of KATP channel subunit expression and function, the switch in leptin's effect on NAG neurons, the ingrowth of inhibitory inputs to NAG neurons, and the development of homeostatic feedback to feeding circuits were delayed in LL offspring relative to controls. The development of functional KATP channels and the establishment of leptin-mediated suppression of food intake in the peri-weaning period were tightly linked and were not initiated until growth and adiposity of LL offspring caught up to controls. CONCLUSIONS Our data support the idea that initiation of KATP channel subunit expression in NAG neurons serves as a molecular gatekeeper for the maturation of homeostatic feeding circuits.

Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013. BIOMEDICAL AND ENVIRONMENTAL SCIENCES : BES 2016; 29:165-176. [PMID: 27109127 DOI: 10.3967/bes2016.021] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 02/18/2016] [Accepted: 03/10/2016] [Indexed: 06/05/2023]
Abstract
OBJECTIVE To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013). METHODS The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census (2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. RESULTS The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. CONCLUSION The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups.

Is undernutrition prognostic of infection complications in children undergoing surgery? A systematic review. J Hosp Infect 2016; 93:12-21. [PMID: 26897556 DOI: 10.1016/j.jhin.2015.12.020] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2015] [Accepted: 12/30/2015] [Indexed: 11/22/2022]
Abstract
BACKGROUND Healthcare-associated infections are costly and are increasingly viewed as an indicator of the quality of care. Although strategies to reduce infections have become widespread, few studies have formally investigated the role of undernutrition on the development of infection-related complications in children after surgery. AIM To perform a systematic review of the literature to determine if undernutrition is prognostic of postoperative infection complications in children. METHODS Electronic bibliographic and research databases were searched from 1950 to 2014. Inclusion criteria were studies in children (age <18 years) evaluating pre-operative nutritional status and reporting postoperative infection complications. Quality assessment was performed independently by two reviewers, with disagreements resolved by a third reviewer. The quality of the evidence was judged to be low in the majority of studies. FINDINGS Ten cohort and two case-control studies met the inclusion criteria. Five studies reported an outcome combining infection-related complications, with the remainder reporting individual infection complications. Six studies reported surgical site infection (SSI) alone or in combination with other infection complications. Direct comparison between studies was difficult due to clinical and diagnostic heterogeneity. Unadjusted analyses (for patient or clinical variables) were suggestive of a relationship between undernutrition and infection complications. In studies controlling for other variables, the analyses did not remain significant for SSI. CONCLUSION There was low-quality evidence that undernutrition may be predictive of postoperative infection complications in children, with the exception of SSI. However, inconsistencies in nutritional and outcome assessments made it difficult to draw conclusions. Larger, high-quality studies are warranted to further investigate a potential prognostic relationship.

Nutritional status and dental fluorosis among schoolchildren in communities with different drinking water fluoride concentrations in a central region in Mexico. THE SCIENCE OF THE TOTAL ENVIRONMENT 2016; 541:512-519. [PMID: 26426374 DOI: 10.1016/j.scitotenv.2015.09.085] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/08/2015] [Revised: 09/16/2015] [Accepted: 09/16/2015] [Indexed: 06/05/2023]
Abstract
UNLABELLED Poor water quality and under nutrition are important factors affecting the health of many communities in developing countries. The aims of this study were: i) to describe the fluoride water concentration and the hydrogeological conditions in a region of a state located in the central in Mexico ii) to measure the association between undernutrition and dental fluorosis in children living in communities with different drinking water fluoride concentrations in a state located in the central region of Mexico. METHODS Field work was performed in the region to identify the prevailing groundwater flow characteristics and water wells were sampled to analyze water fluoride concentration. Children were selected from three communities that had different drinking water fluoride concentrations (i.e., 0.56, 0.70 and 1.60 mg/l). Fluoridated salt was available in these communities. The Thylstrup-Fejerskov Index (TFI) was used to assess dental fluorosis. Categories four or higher of this index involve changes in the entire tooth surface (ITF ≥ 4). The weight and height of the children were measured. The assessment of undernutrition was based on the World Health Organization criteria: children were classified as being at risk of low-height (Height-for-Age Z score < − 1.0 SD) and having low-height (Height-for-Age Z score < − 2.0 SD) for age and sex, the same cutoff points of the Z score were used to classify "risk of low-weight" and" low-weight children". RESULTS In the region the mineralization of the water captured by the wells is the result of a reaction with volcanic materials. The water fluoride concentration in the region ranged from 0.2 to 1.6 mg/l. A total of 734 schoolchildren participated in the study. The percentage of children in fluorosis categories (ITF ≥ 4) was 15.9%, 21.1% of the children were at risk of low height-for-age, and 8.0% had low height-for-age. The percentage of children with fluorosis (ITF ≥ 4) was 6.3%, 9.1% and 31.9% (p ˂ 0.001) and low high-for-age was 2.9%, 2.5% and 8.4% (p ˂ 0.001), for the communities with F concentrations of 0.56 mg/l, 0.70 mg/l and 1.6 mg/l, respectively. The logistic regression model showed an association between dental fluorosis (TFI ≥ 4) and low height-for-age (OR 2.09, p = 0.022) after adjusting for sex, number of teeth erupted, source of drinking water, use of fluoridated toothpaste and tap water fluoride concentration in the community. CONCLUSION Children with low height-for-age were more likely to have dental fluorosis in the TFI categories that affect the entire tooth surface. The results suggest that subpopulations with chronic undernutrition are more susceptible to dental fluorosis.

Abstract
Ongoing population ageing is one of the factors influencing the increase in the prevalence of undernutrition, as elderly people are a vulnerable group due to their biological, psychological and social characteristics. Despite its high prevalence, undernutrition is underdiagnosed in the geriatric sphere. For this reason, the aim of this consensus document is to devise a protocol for geriatric nutritional assessment. A multidisciplinary team has been set up within the Spanish Society of Geriatrics and Gerontology (in Spanish Sociedad Española de Geriatría y Gerontología [SEGG]) in order to address undernutrition and risk of undernutrition so that they can be diagnosed and treated in an effective manner. The MNA-SF is a practical tool amongst the many validated methods for nutritional screening. Following suspicion of undernutrition, or after establishing the presence of undernutrition, a full assessment will include a detailed nutritional history of the patient. The compilation of clinical-nutritional and dietetic histories is intended to help in identifying the possible risk factors at the root of a patient's undernutrition. Following this, an anthropometric assessment, combined with laboratory data, will describe the patient's physical and metabolic changes associated to undernutrition. Currently, the tendency is for further nutritional assessment through the use of non-invasive techniques to study body composition in association with functional status. The latter is an indirect index for nutritional status, which is very interesting from a geriatrician's point of view. To conclude, correct nutritional screening is the fundamental basis for an early undernutrition diagnosis and to assess the need for nutritional treatment. In order to achieve this, it is fundamental to foster research in the field of nutritional geriatrics, in order to expand our knowledge base and to increasingly practice evidence-based geriatrics.

Abstract
OBJECTIVE The present study aimed to evaluate the clustering of undernutrition indicators of children under the age of 5 years in relation to different scales. DESIGN A community-based cross-sectional study design was employed. We collected anthropometric data, geographic locations/elevations of households and other data from visited households. We used a retrospective purely spatial Poisson probability model to identify and locate clusters (high rates) of stunting and wasting using the software SaTScan™ version 9·1·1. We ran a logistic regression model to help evaluate the causes of clustering. Settings Six villages in the Meskane Mareko District (38·45763°E, 8·042144°N) of southern Ethiopia. SUBJECTS We surveyed 2371 children aged <5 years, who were found in 1744 households. RESULTS We found a micro-level variation in the risk of stunting and wasting within the studied district. We found the most likely significant clusters for wasting and severe wasting in two of the six villages. For stunting, a single large cluster size of 390 cases (304·19 expected) in 756 households was identified (relative risk=1·48, P<0·01). For severe stunting, a single cluster size of 106 cases (69·39 expected) in 364 households was identified (relative risk=1·69, P=0·035). CONCLUSIONS We conclude that the distribution of wasting and stunting was partly spatially structured. We identified distinct areas within and between villages that have a higher risk than the underlying at-risk population. Our analysis identified the spatial locations of high-risk areas for stunting that could be an input for geographically targeting and optimizing nutritional interventions.

DJ-1 protects against undernutrition-induced atrophy through inhibition of the MAPK-ubiquitin ligase pathway in myoblasts. Life Sci 2015; 143:50-7. [PMID: 26408915 DOI: 10.1016/j.lfs.2015.09.016] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2015] [Revised: 08/01/2015] [Accepted: 09/21/2015] [Indexed: 01/09/2023]
Abstract
AIMS The purpose of this study is to explore whether antioxidant DJ-1 protein affects the atrophy of skeletal muscle cell induced by undernutrition. MAIN METHODS To determine cell atrophic responses, L6 cell line and skeletal primary cells from mouse hind limbs were cultivated under condition of FBS-free and low glucose. Changes of protein expression were analyzed using Western blot. Overexpression and knockdown of DJ-1 was performed in cells to assess its influence on cell atrophic responses. KEY FINDINGS Undernutrition decreased cell size and increased the abundance of oxidized form and total form of DJ-1 protein in L6 myoblasts. The undernourished cells revealed an elevation in the expression of muscle-specific RING finger-1 (MuRF-1) and atrogin-1, and in the phosphorylations of p38 mitogen-activated protein kinase (MAPK) and stress-activated protein kinase/c-Jun N-terminal kinase compared with control groups. Moreover, DJ-1-knockout mice showed a decrease in cell size and an enhancement in the expression of MuRF-1 and atrogin-1, as well as in the phosphorylation of MAPKs in gastrocnemius muscles; these changes were also observed in L6 cells transfected with siRNA of DJ-1. On the other hand, L6 cells overexpressing full-length DJ-1 did not exhibit the alterations in cell size and ubiquitin ligases seen after undernourished states of control cells. Myotubes differentiated from L6 cells also showed elevated expression of MuRF-1 and atrogin-1 in response to undernutrition. SIGNIFICANCE These results suggest that DJ-1 protein may contribute to undernutrition-induced atrophy via MAPKs/ubiquitin ligase pathway in skeletal muscle cells.

Abstract
This paper examines how the profile of undernutrition among children in two African countries (Ethiopia and Nigeria) changed over the period of the 2007/08 food, fuel and financial crisis. Using the Composite Index of Anthropometric Failure (CIAF), an indicator which allows for a comprehensive assessment of undernutrition in young children, we examine what changes occurred in the composition of undernutrition, and how these changes were distributed amongst children in different socio-economic groups. This is important as certain combinations of anthropometric failure (AF), especially the experience of multiple failures (dual and triple combinations of AF) are associated with higher morbidity and mortality risks, and are also related to poverty. Our hypothesis is that increases in food prices during the crisis contributed to an increase in inequality, which may have resulted in concurrent increases in the prevalence of more damaging forms of undernutrition amongst poorer children. While both countries witnessed large increases in food prices, the effects were quite different. Ethiopia managed reduce the prevalence of multiple anthropometric failure between 2005 and 2011 across most groups and regions. By contrast, in Nigeria prevalence increased between 2008 and 2013, and particularly so in the poorer, northern states. The countries studied applied quite different policies in response to food price increases, with the results from Ethiopia demonstrating that protectionist public health and nutrition interventions can mitigate the impacts of price increases on poor children.

Abstract
Little is known about the effects of undernutrition on the specific muscles and neuronal circuits involved in mastication. The aim of this study was to document the effects of neonatal low-protein diet on masticatory efficiency. Newborn rats whose mothers were fed 17% (nourished (N), n 60) or 8% (undernourished (U), n 56) protein were compared. Their weight was monitored and their masticatory jaw movements were video-recorded. Whole-cell patch-clamp recordings were performed in brainstem slice preparations to investigate the intrinsic membrane properties and N-methyl-d-aspartate-induced bursting characteristics of the rhythmogenic neurons (N, n 43; U, n 39) within the trigeminal main sensory nucleus (NVsnpr). Morphometric analysis (N, n 4; U, n 5) were conducted on masseteric muscles serial cross-sections. Our results showed that undernourished animals had lower numbers of masticatory sequences (P=0·049) and cycles (P=0·045) and slower chewing frequencies (P=0·004) (N, n 32; U, n 28). Undernutrition reduced body weight but had little effect on many basic NVsnpr neuronal electrophysiological parameters. It did, however, affect sag potentials (P<0·001) and rebound firing (P=0·005) that influence firing pattern. Undernutrition delayed the appearance of bursting and reduced the propensity to burst (P=0·002), as well as the bursting frequency (P=0·032). Undernourished animals showed increased and reduced proportions of fibre type IIA (P<0·0001) and IIB (P<0·0001), respectively. In addition, their fibre areas (IIA, P<0·001; IIB, P<0·001) and perimeters (IIA, P<0·001; IIB, P<0·001) were smaller. The changes observed at the behavioural, neuronal and muscular levels suggest that undernutrition reduces chewing efficiency by slowing, weakening and delaying maturation of the masticatory muscles and the associated neuronal circuitry.

Abstract
Nearly 40% of the world's stunted children live in India and the prevalence of undernutrition has been persistently high in recent decades. Given numerous available interventions for reducing undernutrition in children, it is not clear of the relative importance of each within a multifactorial framework. We assess the simultaneous contribution of 15 known risk factors for child chronic undernutrition in India. Data are from the 3rd Indian National Family Health Survey (NFHS-3), a nationally representative cross-sectional survey undertaken in 2005-2006. The study population consisted of children aged 6-59 months [n = 26,842 (stunting/low height-for-age), n = 27,483 (underweight/low weight-for-age)]. Risk factors examined for their association with undernutrition were: vitamin A supplementation, vaccination, use of iodized salt, household air quality, improved sanitary facilities, safe disposal of stools, improved drinking water, prevalence of infectious disease, initiation of breastfeeding, dietary diversity, age at marriage, maternal BMI, height, education, and household wealth. Age/sex-adjusted and multivariable adjusted effect sizes (odds ratios) were calculated for risk factors along with Population Attributable Risks (PAR) and Fractions (PAF) using logistic regression. In the mutually adjusted models, the five most important predictors of childhood stunting/underweight were short maternal stature, mother having no education, households in lowest wealth quintile, poor dietary diversity, and maternal underweight. These five factors had a combined PAR of 67.2% (95% CI: 63.3-70.7) and 69.7% (95% CI: 66.3-72.8) for stunting and underweight, respectively. The remaining factors were associated with a combined PAR of 11.7% (95% CI: 6.0-17.4) and 15.1% (95% CI: 8.9-21.3) for stunting and underweight, respectively. Implementing strategies focused on broader progress on social circumstances and infrastructural domains as well as investments in nutrition specific programs to promote dietary adequacy and diversity are required to ensure a long term trajectory of optimal child growth and development in India.

Abstract
BACKGROUND Adolescence is last chance for curbing the consequences of malnutrition and breaking the intergenerational cycle of malnutrition and poor health. This study aimed to assess the prevalence and the factors associated with stunting and thinness among in-school adolescents in northern Ethiopia using the 2006 World Health Organization (WHO) standards. METHODS In-school adolescents (n = 348, 10-19 years old) were randomly selected to participate in this cross-sectional study. Anthropometric measurements were carried out to determine the proportion of adolescents who were stunted (height-for-age < -2 Standard Deviation (SD)) and thin (body-mass-index-for-age < -2 SD). T-test was employed to evaluate mean weight and height differences between groups. Pearson chi-square, chi-square trend and Fisher's exact tests were used to explore the crude association of categorical outcome variables and associated factors. Crude and adjusted associations between the outcome variables (stunting and thinness) and independent variables (socio-demographic, eating behavior and sanitation) were also determined using logistic regression. Stata version 11.1 was used to analyze the data. RESULTS The height of the adolescents was 147.6 ± 11.2 cm (mean ± SD) and weight was37.2 ± 9.5 kg. The mean Z-scores of height-for-age and body-mass-index (BMI)-for-age of adolescents were -1.49 and -1.29, respectively. The prevalence of stunting and thinness among adolescents was 28.5 % (boys = 37.7 %; girls = 21.2 %; P = 0.001) and 26.1 % (boys = 32.4; girls = 21.6 %; p = 0.017), respectively. Adolescents in 13-15 year old age group (Adjusted Odds ratio (AOR) = 2.23; 95 % CI: 1.22, 4.08), boys (AOR = 2.53; 95 % CI: 1.52, 4.21) and rural residents (AOR = 2.15; 95 % CI: 1.20, 3.86) had significantly higher odds of being stunted compared to their counterparts. Furthermore, boys had higher (AOR = 1.97; 95 % CI: 1.19, 3.25) odds of being thin compared to girls. Compared to those 10 to 12 years of age, adolescents in 16 to 19 years of age were 53 % (AOR = 0.47; 95 % CI: 0.23, 0.95) less likely to be thin. CONCLUSIONS Undernutrition is widely prevalent among adolescents in northern Ethiopia. Sex, age and area of residence significantly associated with adolescent undernutrition. The study underlines the need for nutrition interventions targeting rural and boy adolescents.

Abstract
Undernutrition during brain development causes long lasting alterations in different neurotransmitter systems that may alter responses to psychoactive drugs. Despite the recognized effects of early undernutrition on the cholinergic system, no evidence that demonstrates the influence of this insult on nicotine susceptibility has been reported. We investigated the effects of protein/calorie restriction during lactation on the susceptibility to nicotine in adolescent mice. Dams were randomly assigned to one of the following groups: Control (C, 20 litters)--free access to standard laboratory diet (23% protein); Protein Restricted (PR, 12 litters)--free access to a isoenergetic, 8% protein diet; Calorie Restricted (CR, 12 litters)--access to standard laboratory diet in restricted quantities (mean ingestion of PR: pair-fed group). Undernutrition extended from postnatal day 2 (PN2) to weaning (PN21). At PN30, animals either received an i.p. injection of nicotine (0.5mg/Kg) or saline and were immediately placed in open field (OF). After the OF, adrenal glands and serum were collected for the analyses of stress-related endocrine parameters and leptin concentration. PR and CR offspring showed less body mass gain and visceral fat mass. PR offspring presented reduced serum leptin concentration. In the OF, nicotine increased locomotor activity of C and PR, but not of CR. CR and PR offspring showed decreased adrenal catecholamine content, which was not dependent on nicotine exposure. Our results indicate that early undernutrition interferes with nicotine-elicited locomotor effects in adolescent mice and suggest that endocrine parameters alterations in malnourished animals do not influence the behavioral response to nicotine.

Abstract
Some progress has been achieved in reducing the prevalence of undernutrition among children under 5 years of age in Tanzania. In the Rukwa region (2010), the level of stunted and underweight children was 50·4 and 13·5 %, respectively. The aim of this study was to assess the nutritional status of children under 5 years of age, feeding practices and risk factors of undernutrition in a rural village in the Rukwa region, as well as to discuss the results in light of a similar study conducted in 1987/1988. This cross-sectional study was conducted in 152 households with children under 5 years of age. Data were obtained from the child's main caretaker and the household head, using a structured questionnaire and a 24 h dietary recall. Children's length/height and weight were measured. The prevalence of stunting and underweight was found to be 63·8 and 33·6 % (Z-score<-2 of WHO 2006 CGS), respectively. Sugar-water was given to 72·3 % of the children on the first day after birth. A thin gruel was introduced after a median of 2 months (25th-75th percentiles; 1-3). The time mothers spent farming was a significant risk factor for stunting (P=0·04). Illness, food shortage and dry-season cultivation were significant risk factors for underweight (P<0·01). Using the NCHS/WHO 1983 growth reference (<75 % of the median), the prevalence of underweight was 25·0 %, similar to that reported in 1987/1988 (26·4 %). In conclusion, the underweight prevalence was found to be at the same level in 2010 as was recorded in 1987/1988. Current child-feeding practices were not in line with WHO recommendations. Women working in farms, food shortage, dry-season cultivation and diseases partly explain the children's poor nutritional status.
