As a first approach of the Nutritional problematic of the area, the study shows the most referred foods in the interviews, which are non industrialized basic foods, source of energy and of lower cost

Nutritional conditions indicators in Polonoroeste Area: I. Methodological aspects and social-economic characteristics

O trabalho apresenta os princípios metodológicos que nortearam a organização da Pesquisa Inquérito Nutricional no Polonoroeste. Foram incluídas, também as informações sobre as características sócio-econômicas e sanitárias das famílias estudadas em 1985 na zona urbana de Cáceres-MT. Destas 74% eram radicadas em Cáceres e 13,5% provinham de outros estados ou de outros países, sendo que 76,2% residiam em zona urbana. Quanto a categoria social e renda 52% eram urbanos e 51,0% recebia menos de 2 salários mínimos. O inquérito não atingia os 2 setores mais pobres e populosos da cidade onde as condições são piores e onde vive a maioria da população que migrou mais recentemente para Caceres.The work presents the methodological principles which lead Nutritional inquires Survey of Polonoroeste/MT organization. Were, also, included the informations about the social-economic and sanitary characteristics, of families studied in 1985, in the Cáceres/MT urban zone

Indicadores das condições nutricionais na região do polonoroeste: II. Estudo antropométrico - 1983

Realizou-se o estudo do estado nutricional através da antropometria com o objetivo de descrever a prevalência e a forma da Desnutrição Protéico-Energética em seis cidades da região do Polonoroeste. O exame antropométrico foi aplicado em um grupo de 573 crianças de 3 a 72 meses de idade, de ambos os sexos. Para o tratamento dos dados coletados utilizou-se as classificações propostas por GOMEZ e por WATERLOW, sendo ainda realizada a distribuição do peso e a altura por faixas de percentis. A prevalência de desnutrição encontrada, segundo a classificação de GOMEZ, foi de 51,0%, sendo que o maior percentual foi constatado na cidade de Jauru (79,2%) e o menor na cidade de Araputanga (31,3%). Quanto à forma de desnutrição a de maior prevalência foi a desnutrição pregressa, mostrando com isso um comprometimento acentuado da estatura, confirmado através da distribuição por percentis.A study of the nutritional state through anthropometry was made in order to describe the prevalence and the protein-energetic undernutrition form within six cities of Polonoroeste/MT area. The anthropometric test was done over a group of 573 children from 3 to 72 months old, of both sex. For the manipulation of the collected data, the classification proposed by GOMEZ and WATERLOW was used, being still done the distribution of weight and height in percentage ranges. Following GOMEZ classification the undernutrition prevalence met was of 51%, being that the highest percentage found was in the city of Jauru (79.2%) and the lowest in Araputanga city (31.3%). As for the undernutrition form, the highest prevalence was the past undernutrition showing an accentuated compromise of the height confirmed through the percentage distribution

Nutritional status indicators in Polonoroeste Area: III - clinical nutritional study

This work is part of the clinical nutritional evaluation of the "Health Diagnostic in the Polonoroeste Survey, 1983". With the objective of evaluating the nutritional status of the population in the area of Polonoroeste a Nutritional Inquiry was done in 7 cities of the State of Mato Grosso. The inquiry included a study of alimentary habits, anthropometric studies and a clinical evaluation of the nutritional status of children between 3 and 72 months of age. We examined 585 children selected as proposed by the SANCHES & CARVALHEIRO sampling method modified by MEIRELLES and SANCHES and the clinical-nutritional evaluation was made according to JELLIEFE. Clinical evidence of proteic-energetic malnutrition was registered in 6.6% of the children, anemia in 9.7% and goiter in 2.7%. There was correlation of the anemia with intestinal parasitoses observed in the same sample by another team of the same project.O estudo do exame clínico-nutricional é parte do Inquérito Nutricional, realizado no "Diagnóstico em Saúde do Polonoroeste-MT em 1983". No intuito de reconhecer a situação nutricional da população da região em estudo, o grupo do Inquérito Nutricional procedeu ao estudo do Consumo Alimentar das famílias, ao estudo dos dados antropométricos e de sinais clínico-nutricionais de crianças na faixa etária de 3 a 72 meses. Foram examinadas 585 crianças da amostra como proposta por SANCHES & CARVALHEIRO7 adaptado por MEIRELLES e SANCHES. O exame clínico-nutricional foi realizado segundo a metodologia recomendada por JELLIFFE4. Foram encontrados sinais clínicos sugestivos de carência nutricional em 6,6% das crianças; sinais de anemia em 9,7% e de bócio em 2,7%. Não foi possível definir com precisão outros quadros carenciais

Two truncating variants in FANCC and breast cancer risk

Fanconi anemia (FA) is a genetically heterogeneous disorder with 22 disease-causing genes reported to date. In some FA genes, monoallelic mutations have been found to be associated with breast cancer risk, while the risk associations of others remain unknown. The gene for FA type C, FANCC, has been proposed as a breast cancer susceptibility gene based on epidemiological and sequencing studies. We used the Oncoarray project to genotype two truncating FANCC variants (p.R185X and p.R548X) in 64,760 breast cancer cases and 49,793 controls of European descent. FANCC mutations were observed in 25 cases (14 with p.R185X, 11 with p.R548X) and 26 controls (18 with p.R185X, 8 with p.R548X). There was no evidence of an association with the risk of breast cancer, neither overall (odds ratio 0.77, 95% CI 0.44-1.33, p = 0.4) nor by histology, hormone receptor status, age or family history. We conclude that the breast cancer risk association of these two FANCC variants, if any, is much smaller than for BRCA1, BRCA2 or PALB2 mutations. If this applies to all truncating variants in FANCC it would suggest there are differences between FA genes in their roles on breast cancer risk and demonstrates the merit of large consortia for clarifying risk associations of rare variants.Peer reviewe

Associations of obesity and circulating insulin and glucose with breast cancer risk: a Mendelian randomization analysis.

BACKGROUND: In addition to the established association between general obesity and breast cancer risk, central obesity and circulating fasting insulin and glucose have been linked to the development of this common malignancy. Findings from previous studies, however, have been inconsistent, and the nature of the associations is unclear. METHODS: We conducted Mendelian randomization analyses to evaluate the association of breast cancer risk, using genetic instruments, with fasting insulin, fasting glucose, 2-h glucose, body mass index (BMI) and BMI-adjusted waist-hip-ratio (WHRadj BMI). We first confirmed the association of these instruments with type 2 diabetes risk in a large diabetes genome-wide association study consortium. We then investigated their associations with breast cancer risk using individual-level data obtained from 98 842 cases and 83 464 controls of European descent in the Breast Cancer Association Consortium. RESULTS: All sets of instruments were associated with risk of type 2 diabetes. Associations with breast cancer risk were found for genetically predicted fasting insulin [odds ratio (OR) = 1.71 per standard deviation (SD) increase, 95% confidence interval (CI) = 1.26-2.31, p  =  5.09  ×  10-4], 2-h glucose (OR = 1.80 per SD increase, 95% CI = 1.3 0-2.49, p  =  4.02  ×  10-4), BMI (OR = 0.70 per 5-unit increase, 95% CI = 0.65-0.76, p  =  5.05  ×  10-19) and WHRadj BMI (OR = 0.85, 95% CI = 0.79-0.91, p  =  9.22  ×  10-6). Stratified analyses showed that genetically predicted fasting insulin was more closely related to risk of estrogen-receptor [ER]-positive cancer, whereas the associations with instruments of 2-h glucose, BMI and WHRadj BMI were consistent regardless of age, menopausal status, estrogen receptor status and family history of breast cancer. CONCLUSIONS: We confirmed the previously reported inverse association of genetically predicted BMI with breast cancer risk, and showed a positive association of genetically predicted fasting insulin and 2-h glucose and an inverse association of WHRadj BMI with breast cancer risk. Our study suggests that genetically determined obesity and glucose/insulin-related traits have an important role in the aetiology of breast cancer

A case-only study to identify genetic modifiers of breast cancer risk for BRCA1/BRCA2 mutation carriers

Breast cancer (BC) risk for BRCA1 and BRCA2 mutation carriers varies by genetic and familial factors. About 50 common variants have been shown to modify BC risk for mutation carriers. All but three, were identified in general population studies. Other mutation carrier-specific susceptibility variants may exist but studies of mutation carriers have so far been underpowered. We conduct a novel case-only genome-wide association study comparing genotype frequencies between 60,212 general population BC cases and 13,007 cases with BRCA1 or BRCA2 mutations. We identify robust novel associations for 2 variants with BC for BRCA1 and 3 for BRCA2 mutation carriers, P < 10−8, at 5 loci, which are not associated with risk in the general population. They include rs60882887 at 11p11.2 where MADD, SP11 and EIF1, genes previously implicated in BC biology, are predicted as potential targets. These findings will contribute towards customising BC polygenic risk scores for BRCA1 and BRCA2 mutation carriers
