Evolution and Epidemic Spread of the Avian Infectious Bronchitis Virus (IBV) GI-23 in Brazil.

Infectious bronchitis virus (IBV) is a pathogen affecting poultry flocks worldwide. GI-23 is an IBV lineage with a rapid spread into different continents of the world, and it was reported for the first time in South American/Brazilian broiler farms last year. This study aimed to investigate the recent introduction and epidemic spread of IBV GI-23 in Brazil.

Evaluation of Meiofauna in the Hyporheic Zone of the Beberibe River, Pernambuco, Brazil.

  The hyporheic environment is composed of a rich meiofauna that depends on water flow, organic matter, and oxygen. The concentration of meiofauna varies spatially (horizontal and vertical) and temporally. Several processes occur at this interface (groundwater and surface water), including biogeochemical processes involving meiofauna.

Characterization of Oral Microbiota in Removable Dental Prosthesis Users: Influence of Arterial Hypertension.

Introduction: Studies have described the possible relation between oral infections and atherosclerotic events.

Objective: To characterize the oral microbiota of normotensive and hypertensive users of dental prostheses.

Methods: The sample consisted of 41 complete dental prosthesis users, divided into groups: 21 participants with systemic arterial hypertension and 20 normotensive participants.

Use of noninvasive procedures in the cardiovascular risk assessment of hypertensive and normotensive individuals.

Background: Arterial hypertension is associated with a high prevalence of vascular alterations. The use of noninvasive procedures to assess peripheral arterial diseases in the ranking of cardiovascular risks has been increasingly valued in clinical practice and should be adopted in nursing.

Objective: To identify the cardiovascular risk of hypertensive and normotensive individuals through the use of different noninvasive procedures to assess the vascular function and integrity: ankle-brachial index, pulse pressure, and delta brachial-brachial and delta ankle-brachial indexes.

Occurrence of Cryptosporidium spp., Giardia spp. and other pathogenic intestinal parasites in the Beberibe River in the State of Pernambuco, Brazil.

Introduction: Transmission of pathogenic protozoa and helminths by water is a serious public health problem. In this study, we analyzed the presence of these organisms in the Beberibe River in Pernambuco, Brazil.

Methods: Parasite analysis was performed using the Hoffman, Pons, & Janer method followed by centrifugation and preparation of slides by staining with acetic acid and Lugol's solution.

Comparative analysis of non-adherence to medication treatment for systemic arterial hypertension in urban and rural populations.

Objective: to evaluate the indexes and the main factors associated with non-adherence to medication treatment for systemic arterial hypertension between urban and rural areas.

Method: analytical study based on an epidemiological survey with a sample of 247 hypertensive residents of rural and urban areas, with application of a socio-demographic and economic questionnaire, and treatment adherence assessment. The Pearson's Chi-square test was used and the odds ratio (OD) was calculated to analyze the factors related to non-adherence.

Hypotensive response magnitude and duration in hypertensives: continuous and interval exercise.

Background: Although exercise training is known to promote post-exercise hypotension, there is currently no consistent argument about the effects of manipulating its various components (intensity, duration, rest periods, types of exercise, training methods) on the magnitude and duration of hypotensive response.

Objective: To compare the effect of continuous and interval exercises on hypotensive response magnitude and duration in hypertensive patients by using ambulatory blood pressure monitoring (ABPM).

Methods: The sample consisted of 20 elderly hypertensives.

Cardiovascular risk in white coat hypertension: an evaluation of the ankle brachial index.

The aim in this study was to identify the cardiovascular risk in patients suffering from white coat hypertension (WCH) by determining the ankle brachial index (ABI) with an automatic oscillometric sphygmomanometer. The study was undertaken in a Brazilian city between August 2010 and June 2011. The study variables were age, ethnic origin, marital status, education level, profession, weight, height, waist circumference, arm and ankle blood pressure (BP), and ABI.
