| ABSTRACT The objective of this study was to conduct an investigation of Mycoplasma bovigenitalium and Ureaplasma diversum infections in cattle in the microregion of the Ipanema Valley, state of Pernambuco, Brazil. Vaginal swabs were collected from 355 breeding cows in reproductive age and were analyzed by multiplex PCR (mPCR) and culture. An epidemiological investigation of risk factors was performed for Mollicutes. mPCR analysis showed that, 9.29% (33/355) of the cows were positive for M. bovigenitalium and 21.69% (77/355) for U. diversum; coinfection was observed in 2.81% (10/355) of the cows. The microbiological isolation showed, 81.81% (27/33) of Mycoplasma spp. and 24.67% (19/77) of Ureaplasma spp.. The risk factors related to Mollicutes infection... |

| Many factors appear to influence the chance of acquiring Clostridium difficile (C. difficile) infection, and an accurate identification of risk factors could be beneficial in many ways. Thus, in the present study, clinical risk factors for C. difficile-associated disease (CDAD) in Korea were identified. A total of 93 patients who met the inclusion criteria and 186 age/gender/ward/admission period-matched control patients were included in this study. Statistically significant associations were found with presence of chronic lung diseases (odds ratio [OR], 3.41; 95% confidence interval [CI], 1.25-9.32; p = 0.017), presence of ileus (OR, 10.05; 95% CI, 2.42-41.80; p = 0.001), presence of intensive care unit (ICU) stay (OR, 9.79; 95% CI, 3.03-31.68; p <... |

| Invasive infections caused by Candida spp. are an important problem in immunocompromised patients. There is scarce data on the epidemiology of blood stream candidiasis in Salvador, Brazil. This study evaluates the risk factors associated with candidemia, among patients admitted to three tertiary, private hospitals, in Salvador, Brazil. We conducted a case-control, retrospective study to compare patients with diagnosis of candidemia in three different tertiary hospitals in Salvador, Brazil. Patients were matched for nosocomial, acquired infections, according to the causal agent: cases were defined by positive blood cultures for Candida species. Controls were those patients who had a diagnosis of systemic bacterial infection, with a positive blood culture to... |

| Although most recent publications focus on Ventilator-associated Pneumonia, Non-Ventilator-associated Hospital-acquired pneumonia (NVHAP) is still worrisome. We studied risk factors for NVHAP among patients admitted to a small teaching hospital. Sixty-six NVHAP case patients and 66 controls admitted to the hospital from November 2005 through November 2006 were enrolled in a case-control study. Variables under investigation included: demographic characteristics, comorbidities, procedures, invasive devices and use of medications (Sedatives, Antacids, Steroids and Antimicrobials). Univariate and multivariable analysis (hierarchical models of logistic regression) were performed. The incidence of NVHAP in our hospital was 0.68% (1.02 per 1,000 patients-day).... |

| ABSTRACT Background: Effective antiretroviral therapy (ART) has increased life expectancy for HIV patients to levels close to that observed for general population. Comorbidities are also increasing, due to ageing of such population. Erectile dysfunction (ED) has been a frequent finding in men living with HIV. Objectives: The goals of the present study were to define the prevalence of ED and associated factors in HIV-infected men, in a referral center of Salvador city, Brazil. Methods: HIV-infected men ≥18 years of age, receiving care at the AIDS Clinics of Complexo Hospitalar Professor Edgard Santos (C-HUPES), Universidade Federal da Bahia were consecutively included in the study until the estimated sample size (N = 134) was reached. Patients filled a... |

| Objectives: Evaluate risk factors and clinical outcomes of infections caused by Enterobacteriaceae resistant to third-generation cephalosporins present in samples collected upon hospital admission.Methods: Risk factors were evaluated using a 1:2 ratio case-control study. Influence of resistance on the appropriateness of antibiotic therapy, length of stay, and hospital mortality were prospectively evaluated. Characteristics independently associated with the presence of resistant enterobacteria were assessed by logistic regression.Results: Enterobacteria resistant to third-generation cephalosporins were quite common (26.0%). Male gender (OR: 2.66; 95% CI, 1.17-5.06; p= 0.019), invasive prosthesis (OR: 3.79; 95% CI, 1.29-11.08; p= 0.015), previous use of... |

| We examined prevention of surgical site infection (SSI) in a tertiary teaching hospital in northeast Brazil, from January 1994 to December 2003. The survey included 5,742 patients subjected to thoracic, urologic, vascular and general surgery. The criteria for diagnosing SSI were those of the Centers for Disease Control, USA, and the variables of the National Nosocomial Infection Surveillance risk index were used. Data analysis revealed that anesthetic risk scores, wound class and duration of surgery were significantly associated with SSI. A total of 296 SSIs were detected among the 5,742 patients (5.1%). The overall incidence of SSI was 8.8% in 1994; it decreased to 3.3% in 2003. In conclusion, the use of educational strategies, based on guidelines for SSI... |

| The elderly population will grow rapidly over the next 25 years, however there is little information about hospital infections in this group of patients in Brazil. We examined the prevalence of nosocomial and community infections in elderly (>65 years) patients and their relationship with intrinsic and extrinsic risk factors in a Brazilian University Hospital. A total of 155 hospitalized elderly patients were evaluated, and clinical and demographic information about each patient was obtained from hospital records. The rates of nosocomial and community infections were 16.1% and 25.6%, respectively. When the elderly group with and without nosocomial infections was analyzed, practically all the risk factors considered (use of antibiotics, invasive devices,... |

| The aim of this paper was to study some epidemiological aspects of the infection by Brucella abortus in risk occupational groups in the microregion of Araguaína, Tocantins. For antibody research, 645 serum samples were analyzed by the complement fixation test (CF). A 4.0% frequency was found (26/645) in patients' serum and among those 4.1% (23/551) were slaughterhouses employees and 8.1% (3/37) rural workers. Of the total positive samples, three (2.0%) were women and 23 (4.7%) men; ten (2.9%) were between the ages of 18 and 30, six (3.4%) between 31 and 40, and nine (8.0%) were above 41 years of age. Risk factors for brucellosis in the study groups were age, background (OR = 2.45; CI 95% = 0.98 to 6.10) and previous work conducted with production animals... |
