Introduction: The malnutrition in children under 5 years is a serious public health problem in the developing countries such as Mozambique. The stunting can affect cognitive and physical development and compromise the school performance. Method: A cross sectional study was carried out which used the secondary data from a survey conducted by National Health Institute of Mozambique, in districts of Angonia, Tsangano, Magoe and Changara in Tete Province, Mozambique. The polynomial regression model and the hierarchical approach were used to examine the association between social economic factors and malnutrition in children measured by stunting (low height for age) and underweight (low weight for age). Results: The prevalence of moderate and severe stunting was 39.8%, and prevalence of moderate and severe underweight was 19.6%. In the basic level, the households that had 1 durable goods possession were associated to 1.46 times greater than the mild underweight, OR = 1.46 (C.I. 95% 1.02 - 2.11). In the intermediate level, lack of latrine increased 2.01 times greater than the moderate and severe underweight in children, OR = 2.01 (C.I. 95% 1.09 - 3.70);In the immediate level, the child deworming had 1.91 times greater than the moderate and severe stunting, OR = 1.91 (C.I.95% 1.04 - 3.52) and children who did not breastfeed had 2.42 times greater than the moderate and severe stunting, OR = 2.42 (C.I. 1.49 - 3.43). Conclusion: In the countries where the weak health system and the inadequate children food are frequent, the prevalence of undernutrition in children remains very high.

Effects of the Orientation of the Mountainside, Altitude and Varieties on the Quality of the Coffee Beverage from the “Matas de Minas” Region, Brazilian Southeast

Based upon qualitative parameters experiments, this study aims to investigate how the elements of the environment, where the coffee is produced, contribute to the final quality of the product. For the analyses, it was used approximately one kilogram of coffee cherry samples collected in 14 municipalities previously chosen on the East side of the Minas Gerais State, Brazil. The coffee cherry samples were collected and analyzed for each of the two varieties in four levels of altitude for each exposure side of the mountain in relation to the Sun. The quality of the coffee was evaluated through the analysis of its physical characteristics and sensory analysis, popularly known as "Test of drink or Cupping" carried out by three tasters that belonging to the group of Q-Graders, according to the rules of national and international competitions of the Brazilian Association of Special Coffees (BSCA). Were performed analysis by means descriptive statistics, analysis of variance and multivariate analysis, all of them aiming to study the individual sensory characteristics of quality of the coffee beverage from the “Matas de Minas” region. Path coefficient analysis also was carried out for the partition of the phenotypic correlation coefficients into measures of direct and indirect effects, in order to determine the individual sensory characteristics that played a major role in the beverage final score. The results demonstrate that it is not possible to conclusively establish the differences among coffees evaluated with basis on varieties and environmental factors previously cited. It can be concluded that it is not recommended to associate the quality of coffee only to a specific factor whether from the environment or being it a specific of the culture of coffee. However, the cafes that were evaluated had intrinsic quality, which were derived from the specific characteristics of the “Matas de Minas” region where they were grown.

Aim: Hepatitis C virus (HCV) cirrhosis is an important cause of hepatocellular carcinoma (HCC). This study aimed to identify factors of HCC presence among HCV cirrhotic patients with and without small diameter HCC (≤ 3 cm). Methods: A case control transversal study between 1998 and 2003 including 93 patients: 31 with small diameter HCC and 62 without HCC. Groups were matched by age and gender. Multiple logistic regression analysis using Akaike Information Criteria to estimate the probability of HCC was performed. A model score was generated and bootstrap analysis was performed for internal validation. Results: Three significant laboratorial variables for HCC presence were found: alanine aminotransferase > 37 U/L [odds ratio (OR): 7.43 (1.61-34.19),P = 0.01], alpha-fetoprotein > 20 ng/mL [OR: 16.2 (4.17-63.01),P del score with an area under curve of 0.79 (95% CI: 0.7-0.89) was built based on these variables. The negative predictive value of those classified as at low risk of HCC was 99.1%. Conclusion: An easy and practical model score was generated. It may be an auxiliary tool for identification of HCV patients with low probability of small diameter HCC at initial evaluation composed of three serum examinations used in routine outpatient clinical practice.
