RESUMEN
OBJECTIVE: To receive stakeholders' feedback on the new structure of the Nutritional Disorders section of the International Classification of Diseases, 11th Revision (ICD-11). DESIGN: A twenty-five-item survey questionnaire on the ICD-11 Nutritional Disorders section was developed and sent out via email. The international online survey investigated participants' current use of the ICD and their opinion of the new structure being proposed for ICD-11. The LimeSurvey® software was used to conduct the survey. Summary statistical analyses were performed using the survey tool. SETTING: Worldwide. SUBJECTS: Individuals subscribed to the mailing list of the WHO Department of Nutrition for Health and Development. RESULTS: Seventy-two participants currently using the ICD, mainly nutritionists, public health professionals and medical doctors, completed the questionnaire (response rate 16 %). Most participants (n 69) reported the proposed new structure will be a useful improvement over ICD-10 and 78 % (n 56) considered that all nutritional disorders encountered in their work were represented. Overall, participants expressed satisfaction with the comprehensiveness, clarity and life cycle approach. Areas identified for improvement before ICD-11 is finalized included adding some missing disorders, more clarity on the transition to new terminology, links to other classifications and actions to address the disorders. CONCLUSIONS: The Nutritional Disorders section being proposed for ICD-11 offers significant improvements compared with ICD-10. The new taxonomy and inclusion of currently missing entities is expected to enhance the classification and health-care professionals' accurate coding of the full range of nutritional disorders throughout the life cycle.

OBJECTIVE: To determine the presence and to assess the adequacy of the nutritional and eating disorders descriptors in the English and Spanish Wikipedia. METHOD: The terms were obtained from the thesaurus: Medical Subject Headings (MeSH) and APA-Terms. The existence of the terms was confirmed accessing to the Spanish and English editions of Wikipedia via the Internet (http://es.wikipedia.org/). The last date for consultation and calculations was June 8, 2012. RESULTS: A total of 89 descriptors were identified, being 56 (62.92%) of them as terms in the Wikipedia: 42 (47.19%) in the Spanish edition and 56 (62.92%) in English. Significant differences between the two editions were assessed (chi-square = 9.41, df = 1, P <0.001). At the same time, differences between both editions according to the number of references in each term were observed (t-Student = -2,43; gl = 84,87; p = 0,017). However, there were not differences in the status of information being update/obsolete, neither in the number of queries. CONCLUSIONS: The entries related to nutritional and eating disorders terms have not yet reached an optimum level. Differences between english and spanish Wikipedia editions are more related to criteria of content principles (term existence) than adequacy of information. The English edition of Wikipedia has a more scientific endorsement, through the references cited, than the Spanish edition.

Las causas de mortalidad de origen nutricional (MON) no aparecen clasificadas en las sucesivas revisiones de la clasificación internacional de enfermedades (CIE) y no existe un acuerdo para la clasificación más adecuada. El objetivo de este estudio es elaborar, a partir de la última CIE, un listado de causas de MON que sirva como referencia para estudios posteriores. Se realizó un proceso de consenso de expertos en nutrición clínica mediante el método Delphi en dos oleadas para clasificar una lista de causas de MON en cuatro grupos; 1) grupo A: errores congénitos relacionados con la nutrición, 2) grupo B: causas asociadas a otras patologías, 3) grupo C: trastornos por exceso y por defecto, y 4) excluidas. Se sometieron al consenso de los expertos 86 causas, de las cuales se consensuaron 79 (91,9%) causas de MON. Se clasificaron 14(17,7%) causas en el grupo A, 5(6,3%) causas en el grupo B, 37(46,8%) causas en el grupo C y se excluyeron 23(29,1%) causas. Se trata de una primera aportación a la clasificación de las causas de mortalidad de origen nutricional, probablemente debido a la ambigüedad y la disparidad de opiniones entre expertos que presentan estas causas. Esta nueva clasificación será muy útil ya que ayudará a homogeneizar los estudios y así se podrán obtener resultados comparables, usándose como complemento clarificador de la CIE del momento.
The causes of mortality of nutritional origin (MNO) are not classified in the consecutive reviews of the international disease classification (IDC) and there is no agreement for their most proper classification. The objective of this study is to elaborate, using the last ICD as a guide, a list of causes of mortality of nutritional origin which will be used as a reference in future studies. A two round Delphi method was organized with an experts consenssus in clinical nutrition. The experts were asked to classify a list of causes of MNO in 4 groups; 1) group A: congenital errors related to nutrition, 2) group B: Causes associated with other pathologies, 3) group 3: Excess and defect nutrition disorders, and 4) excluded. In total, 86 causes of MNO were taken under the consensus of experts, and 79 (91,9%) came to an agreement. 14 (17,7%) causes were classified in group A, 5 (6,3%) causes in group B, 37(46,8%) causes in group C and 23 (29,1%) were excluded. This is a first approach to the classification of mortality causes of nutritional origin, probably due to the ambiguity and disparity of opinions between experts with respect to these causes. This new classification will be very useful due to the fact that it will enable homogenization of the studies and that way we will have comparable studies, using it as a clarifier annex for the ICD of the moment.

Several studies using animal models have suggested that the effects of nutritional insult on the developing brain are long-lasting and lead to permanent deficits in learning and behavior. Malnutrition can refer to the availability of all the nutrients but in insufficient quantities or it may imply that one or more of essential nutrients is either missing or is present, but in the wrong proportions in the diet. The hypothesis addressed in this study is that different domains of cognitive functioning can be affected by malnutrition and this can be related to the type of nutritional deficiency that the brain has been exposed to during development. To study the effect of nutritional deprivation during brain development, a paradigm of maternal malnutrition during the period of gestation and lactation was used and its effects were studied on the F1 offspring using Swiss albino mice. Three different types of malnutrition were used, that involve, caloric restriction, inadequate amount of protein in the diet and condition of low iron content. Our results show that the domain of spatial memory affected in the F1 generation depended on the kind of malnutrition that the mother was subjected to. Further our study shows that although hippocampal volume was reduced in all F1 pups, hippocampal subregions of the F1 animals were differentially vulnerable depending on type of malnutrition that the mother was subjected to. These results highlight the importance of qualifying the kind of malnutrition that is suffered by the mother during the period of gestation and lactation as it has consequences for the cognitive domain affected in the offspring. Awareness of this should inform prevention strategies in trying to reverse the effects of adverse maternal nutrition during critical periods in brain development.

BACKGROUND AND AIMS: In most hospitals in Vietnam, clinical assessment of nutritional status has yet to become part of the routine clinical history taking and physical examination. It is the aim of this study to apply subjective global assessment (SGA) of nutritional status in surgical patients in the Mekong Delta, Vietnam, to determine the incidence of malnutrition according to SGA and to know whether there was an association between SGA class and infectious complications. METHODS: A prospective, cross-sectional study design was used. SGA of nutritional status was applied. Patients were rated as well nourished (A), moderately malnourished (B) or severely malnourished (C). Infectious complications (wound infection, intra-abdominal abscesses, anastomotic leakage) were recorded. RESULTS: Of the 438 patients assessed, 194 (44.3%) were classified as A, 126 patients (28.8%) were classified as B and 118 patients (26.9%) were classified as C. Of the 274 patients who underwent major abdominal surgery assessed, 61 patients (22.3%) were classified as A, 97 patients (35.4%) were classified as B and 116 patients (42.3%) were classified as C. Weight loss and percent weight loss, muscle wasting, loss of subcutaneous fat, functional capacity and significant gastrointestinal symptoms correlate significantly with the severity of SGA class (P<0.001). The rate of postoperative infectious complications was higher in patients classified as SGA class C (33.6%) than as class A (6%) and B (11%). CONCLUSIONS: A high rate of malnutrition was found, applying SGA of nutritional state in surgical patients in Vietnam. Malnutrition was associated with an increase in infectious complications. Special attention should be paid to weight loss, muscle wasting, loss of subcutaneous fat, functional capacity and gastrointestinal symptoms.

BACKGROUND: Studies are needed to test the relevance of the anthropometric criteria for health and well-being, particularly in developing countries. OBJECTIVE: The objective of the study was to identify the relevance of anthropometric indexes as indicators of nutritional status. DESIGN: The sample consisted of 2316 subjects (n = 1094 males, 1222 females) aged 6-18 y from Mozambique. Anthropometric variables, maturity stage, physical fitness, physical activity, and metabolic fitness were measured. Samples of blood, urine, and feces were obtained. Subjects were classified in 5 nutritional groups labeled normal, low height-for-age (stunted), low weight-for-height (wasted), low height-for-age and low weight-for-height (stunted and wasted), and overweight, according to cutoffs set by a World Health Organization expert committee. Socioeconomic status was classified according to region of residence. RESULTS: Prevalence rates for males and females, respectively, in the nutritional groups were 3.0% and 2.3% (stunted group), 21.9% and 10.0% (wasted group), 3.0% and 0.8% (stunted and wasted group), and 4.8% and 7.7% (overweight group). With control for age, socioeconomic status, and maturity stage, the overweight group performed significantly worse than did the other groups on most of the fitness tests. Compared with the normal group, the 3 undernourished groups performed significantly worse in absolute strength tasks, better in endurance tasks, and equally in flexibility and agility. Very few differences were found in physical activity scores. The 3 undernourished groups had scores for the biochemical indicators that were similar to those of the normal group and had more favorable profiles for blood pressure and cholesterol. CONCLUSIONS: In this population, the cutoffs used to classify overweight status appear to appropriately identify potential health problems. No relevance to health was found for the lower cutoffs identifying undernourished children.

OBJECTIVE: To outline the difficulties and suggest potential solutions in anthropometric assessment of adolescents during humanitarian emergencies. DESIGN: Literature review. SETTING: Multiple settings in which the nutritional status of adolescents has been assessed using anthropometric measurements. SUBJECTS: Adolescents in multiple populations. INTERVENTIONS: None. RESULTS: The use of anthropometry may be more difficult in adolescents than in other age groups because anthropometric indices in normally nourished adolescents change with age and sexual development. Moreover, survey and reference populations may differ in the age at which certain pubertal landmarks are attained, requiring adjustment for differences between survey and reference populations. Adolescent populations may also differ by ethnicity in various body proportions that affect anthropometric indices. Adjustment may be required when the body proportions of adolescents in the reference population differ from those in the population assessed. CONCLUSIONS: Although no definitive recommendation can be made regarding which anthropometric indices are the most appropriate for adolescents, some revisions may improve current practices. Weight-for-height could be used for prepubertal adolescents and body mass index could be used for postpubertal adolescents. Because cut-off points are age-specific, age should be collected as accurately as possible for all adolescents measured during screening or survey activities. The WHO-recommended reference population of US adolescents is inappropriate in most populations of adolescents. Adolescents should never undergo nutritional assessment in isolation; other population subgroups should be included, and other health, nutrition and food data should be collected at the same time. SPONSORSHIP: The United Nations Administrative Committee on Coordination/Sub-Committee on Nutrition.

BACKGROUND: Novel classification nomenclature defining the type of malnutrition by the root cause of the hypoalbuminenia has been developing in the literature since 1999. As the classification of malnutrition became more definite in the literature, the need to assess the type of malnutrition, thereby the root cause(s) and initiate appropriate intervention(s), has become apparent. METHODS: In September 1999, San Diego Dialysis began a continuous quality improvement (CQI) project to assess the root causes of hypoalbuminemia for patients with serum albumin level <3.5 g/dL. An extensive review of the literature was conducted on the subject of malnutrition, inflammation, and the acute-phase reaction. FINDINGS: Two major groups of patients emerged: those consuming adequate protein and calories, yet presenting with hypoalbuminemia, and those suffering from a protein calorie deficit. Observation of the second group showed that although the monthly percentage of patients with hypoalbuminemia remained fairly constant, the names on the list changed from month to month. CONCLUSIONS: The CQI team developed a protocol and a unique nomenclature to classify the types of malnutrition, type I, type IIa, type IIb, or mixed, by adapting the definitions in the literature through clinical practice. Interventions were developed to address each classification of malnutrition.

Malnutrition inflammation complex syndrome (MICS) occurs commonly in maintenance hemodialysis (MHD) patients and may correlate with increased morbidity and mortality. An optimal, comprehensive, quantitative system that assesses MICS could be a useful measure of clinical status and may be a predictor of outcome in MHD patients. We therefore attempted to develop and validate such an instrument, comparing it with conventional measures of nutrition and inflammation, as well as prospective hospitalization and mortality. Using components of the conventional Subjective Global Assessment (SGA), a semiquantitative scale with three severity levels, the Dialysis Malnutrition Score (DMS), a fully quantitative scoring system consisting of 7 SGA components, with total score ranging between 7 (normal) and 35 (severely malnourished), was recently developed. To improve the DMS, we added three new elements to the 7 DMS components: body mass index, serum albumin level, and total iron-binding capacity to represent serum transferrin level. This new comprehensive Malnutrition-Inflammation Score (MIS) has 10 components, each with four levels of severity, from 0 (normal) to 3 (very severe). The sum of all 10 MIS components ranges from 0 to 30, denoting increasing degree of severity. These scores were compared with anthropometric measurements, near-infrared-measured body fat percentage, laboratory measures that included serum C-reactive protein (CRP), and 12-month prospective hospitalization and mortality rates. Eighty-three outpatients (44 men, 39 women; age, 59 +/- 15 years) on MHD therapy for at least 3 months (43 +/- 33 months) were evaluated at the beginning of this study and followed up for 1 year. The SGA, DMS, and MIS were assessed simultaneously on all patients by a trained physician. Case-mix-adjusted correlation coefficients for the MIS were significant for hospitalization days (r = 0.45; P < 0.001) and frequency of hospitalization (r = 0.46; P < 0.001). Compared with the SGA and DMS, most pertinent correlation coefficients were stronger with the MIS. The MIS, but not the SGA or DMS, correlated significantly with creatinine level, hematocrit, and CRP level. During the 12-month follow-up, 9 patients died and 6 patients left the cohort. The Cox proportional hazard-calculated relative risk for death for each 10-unit increase in the MIS was 10.43 (95% confidence interval, 2.28 to 47.64; P = 0.002). The MIS was superior to its components or different subversions for predicting mortality. The MIS appears to be a comprehensive scoring system with significant associations with prospective hospitalization and mortality, as well as measures of nutrition, inflammation, and anemia in MHD patients. The MIS may be superior to the conventional SGA and the DMS, as well as to individual laboratory values, as a predictor of dialysis outcome and an indicator of MICS.

Nutrition is a prime concern for the optimal health of older persons. Nutritional requirements for older persons must take into account the physiologic changes that occur with aging. The gastrointestinal tract is the site of key structural and functional changes that affect nutrient intake and assimilation. A working knowledge of nutritional screening, assessment, and interventions can assist the practitioner in providing quality care for the older patient.

Child Malnutrition has been defined or described in many ways. To summarize the common points, child malnutrition may be defined as a pathological state resulting from inadequate nutrition, including undernutrition (protein-energy malnutrition) due to insufficient intake of energy and other nutrients; overnutrition (overweight and obesity) due to excessive consumption of energy and other nutrients; deficiency diseases due to insufficient intake of one or more specific nutrients such as vitamins or minerals. In the assessment of child malnutrition, a large number of measures are available. Among these measuring methods, Z-score, growth charts, weight-for-length index (WLI), height standard weight, body mass index, skin fold thickness and clinical grading diagnosis standard for child malnutrition are selected for discussion. The same set of anthropometry data of a group of preschool children was analyzed by using different methods. The results showed that it was very difficult to determine the nutritional state of children using a single index. For a given group of children, Z-score method is recommended to observe their height, weight and weight for height at the same time in order to have a comprehensive understanding.

OBJECTIVE: The primary objective of this study was to assess the use of Subjective Global Assessment to identify nutrition-associated complications and death in a geriatric population. A secondary objective was to evaluate the ability of Subjective Global Assessment to identify geriatric residents of long-term care facilities who were undernourished or at risk for developing undernutrition. METHODS: Fifty-three consecutive residents who were > or = 65 years of age and had been residing in a long-term care facility for < 2 weeks were enrolled in the study. The Subjective Global Assessment Classification technique was performed according to the procedure outlined by Detsky and colleagues. Residents were classified as well-nourished (A), mild/moderately undernourished (B) or severely undernourished (C). In addition, a Subjective Global Assessment Composite Score was derived. Subjective Global Assessment measures were compared with two traditional objective measurements of nutritional status: serum albumin and serum total cholesterol. Outcome measurements of nutrition-associated complications were determined over a 3-month period by recording the incidence of major infections, decubitus ulcers, nutrition-related hospital readmissions, and mortality. RESULTS: Sixteen residents (30.2%) were categorized as Subjective Global Assessment class A, 28 residents (52.8%) were class B, and 9 residents (17%) were class C. A significant association was found between nutritional status as determined by Subjective Global Assessment Composite Score and nutrition-associated complications (p<0.05). Subjective Global Assessment Classification was related to death (p<0.05) with severely undernourished residents having the highest mortality rate. Hypoalbuminemia only demonstrated a significant relationship with nutrition-associated complications (p<0.05), whereas hypocholesterolemia was associated with death (p<0.05). CONCLUSIONS: Subjective Global Assessment of nutritional status appears to be a simple, noninvasive and cost-effective tool for assessing nutritional status of geriatric residents in long-term care facilities. This assessment tool is also beneficial for identifying patients with increased risk of nutrition-associated complications as well as death.

OBJECTIVE: To investigate the relationships between nutritional status measured by a comprehensive nutritional assessment including anthropometric measurements, nutritional biological markers, evaluation of dietary intake, and the Mini-Nutritional Assessment (MNA) nutrition screening tool. DESIGN: A prospective study. PARTICIPANTS: One hundred fifty-five older subjects (53 men and 102 women; mean age = 78 years; range = 56-97 years). These participants were hospitalized in a geriatric evaluation unit (n = 105) or free living in the community (n = 50). MEASUREMENT: Weight, height, knee height, midarm and calf circumferences, triceps and subscapular skinfolds, albumin, transthyretin (prealbumin), transferrin, ceruloplasmin, C-reactive protein, alpha1-acid glycoprotein, cholesterol, vitamins A, D, E, B1, B2, B6, B12, folate, copper, zinc, a 3 day food record combined with a food-frequency questionnaire; the MNA nutritional screening. RESULTS: The MNA scores have been found to be significantly correlated to nutritional intake (P < .05 for energy, carbohydrates, fiber, calcium, vitamin D, iron, vitamin B6, and vitamin C), anthropometric and biological nutritional parameters (P < .001 for albumin, transthyretin, transferrin, cholesterol, retinol, alpha-tocopherol, 25-OH cholecalciferol zinc). An MNA score between 17 and 23.5 can identify those persons with mild malnutrition in which nutrition intervention may be effective. CONCLUSIONS: The MNA is a practical, noninvasive, and cost-effective instrument allowing for rapid nutritional evaluation and effective intervention in frail older persons.

Malnutrition is an important predictor of morbidity and mortality. In the non-elderly, a subjective global assessment (SGA) has been developed. It has a high inter-rater agreement, correlates with other measures of nutritional status, and predicts subsequent morbidity. The purpose of this study was to determine the validity and reproducibility of the SGA in a group of patients older than 70 y of age. Consecutive patients from four geriatric/rehabilitation units were considered for the study. Each patient underwent independent nutritional assessments by a geriatrician and senior medical resident. At the completion of the assessment, skinfold caliper measurements were obtained and the patient reclassified according to the results, which were then compared with objective measures of nutritional status. Six-month follow-up was obtained on all patients. The agreement between the two clinicians was 0.48 +/- 0.17 (unweighted kappa), which represents moderate agreement and is less than the reported agreement in nonelderly subjects. Skin calipers improved the agreement between clinicians but did not improve the correlation with other nutritional markers or prediction of morbidity and mortality. There was a correlation between a patient's severely malnourished state and mortality. In addition, patients with a body mass index (BMI) of <75% or >150% age/sex standardized norms had an increased mortality. The SGA is a reproducible and valid tool for determining nutritional status in the elderly. The reproducibility is less than in the nonelderly, which may relate to changes in body composition or ability to obtain an accurate nutritional history.
