Introduction: Hospital-acquired urinary tract infection (HAUTI) is an important cause of morbidity in the elderly population. Objective: Evaluate the occurrence of HAUTI and risk factors associated with it. Method: This is a prospective study of a sample of 332 elderly people, interned in a university hospital. Criteria for defining infection were established by the Center for Diseases and Prevention Control. Statistical analysis of data used calculation of frequencies, odds ratio and logistic regression. The rate of hospital infection was 23.6%. The prevalent topographies of infection were respiratory infections (27.6%), urinary tract infections (26.4%) and surgical wound infections (23.6%, with 21, 20 and 19 episodes, respectively. The HAUTI incidence density associated with urinary catheterization was 24.2 infections by 1,000 catheter-days. The length of hospital stay of patients without nosocomial infection was 6.9 days and with HAUTI was increased in 10.4 (p<0.05).The rate of mortality of patients with HAUTI was 20%. Pathogens were isolated in 75% of episodes of HAUTI and the prevalent were: Escherichia coli (33%) and Pseudomonas aeruginosa (20%). Risk factors found for HAUTI were urinary catheterization implementation (odds ratio (OR) = 43.1; 95% confidence interval (95 CI%) = 3.9 – 311.1), hospitalization with community infection (OR= 21.9; 95% CI = 4.9 – 97.9); vascular diseases (OR=14; 95% CI = 2 – 98); diabetes mellitus (OR= 5.5; 95% CI = 1.4 – 21) and urinary catheterization by more than three days (OR=3.7; 95% CI = 1 – 13.8). Conclusions: HAUTI presented elevated incidence and it increased the length of hospital stay.

The objective of this research was to estimate the productivity (PRODUT) in sc/ha of coffee conilon through the technique of cokriging, using as covariate the production of humid coffee (PROD) in kg and compare the results with estimates obtained by kriging ordinary. The study was conducted in a commercial area of conilon coffee, Coffea canephora Pierre var. conilon, located in São Mateus Municipality, Espirito Santo State. For the field work was sampled the humid coffee production in a sampling grid irregular of 18.5 ha, 87 sampling points in the total. We also determined the production of dry coffee beans and coffee benefited 12% moisture, to obtain the PRODUT variable. After exploratory data analysis, which showed the correlation between variables in the order of 0.899, was performed variogram analysis. Were adjusted theoretical variograms to PROD and PRODUT and cross variogram between two variables. Finally we estimated the value of productivity, both by ordinary kriging as per cokriging. The validation of the estimation by cokriging not shows, however, significant gains in relation to validation by ordinary kriging.

Variations in the phenotypic expression of heterozygous beta thalassemia reflect the formation of different populations. To better understand the profile of heterozygous beta-thalassemia of the Brazilian population, we aimed at establishing parameters to direct the diagnosis of carriers and calculate the frequency from information stored in an electronic database. Using a Data Mining tool, we evaluated information on 10,960 blood samples deposited in a relational database. Over the years, improved diagnostic technology has facilitated the elucidation of suspected beta thalassemia heterozygote cases with an average frequency of 3.5% of referred cases. We also found that the Brazilian beta thalassemia trait has classic increases of Hb A2 and Hb F (60%), mainly caused by mutations in beta zero thalassemia, especially in the southeast of the country.
